PRELIMINARY AND SUBJECT TO CHANGE, DATED APRIL 29, 2019

Offer by

CAMBRIA ACQUISITION CORP.

a direct wholly-owned subsidiary of

TESLA, INC.

to Exchange Each Outstanding Share of Common Stock of

MAXWELL TECHNOLOGIES, INC.

for

$4.75 in Fair Market Value of Shares of Common Stock of Tesla

(subject to the minimum as described in this

prospectus/offer to exchange and the related letter of transmittal)

THE OFFER COMMENCED ON WEDNESDAY, FEBRUARY 20, 2019. THE OFFER AND THE WITHDRAWAL RIGHTS WILL EXPIRE AT 11:59 P.M., EASTERN TIME, AT THE END OF MAY 15, 2019, UNLESS EXTENDED OR TERMINATED.

Tesla, Inc. (“Tesla”), a Delaware corporation, through its direct wholly-owned subsidiary Cambria Acquisition Corp., a Delaware corporation (the “Offeror”), is offering, upon the terms and subject to the conditions set forth in this document and in the accompanying letter of transmittal, to exchange each outstanding share of common stock of Maxwell Technologies, Inc., a Delaware corporation (“Maxwell”), par value $0.10 per share (“Maxwell common stock” and such shares of Maxwell common stock, “Maxwell shares”), that has been validly tendered and not validly withdrawn in the offer for a fraction of a share of Tesla’s common stock, par value $0.001 per share (“Tesla common stock” and such shares of Tesla common stock, “Tesla shares”) equal to the quotient obtained by dividing $4.75 by the volume weighted average of the daily volume weighted average of the trading price of one (1) share of Tesla common stock as reported on the Nasdaq Global Select Market for the five (5) consecutive trading days immediately preceding the second trading day prior to the date of the expiration of the offer, subject to the minimum, plus cash in lieu of any fractional shares of Tesla common stock, without interest and less any applicable withholding taxes. In the event that the Tesla common stock price is equal to or less than $245.90, the minimum will apply and each share of Maxwell common stock validly tendered and not validly withdrawn in the offer will be exchanged for 0.0193 of a share of Tesla common stock. For the avoidance of doubt, if the offer were to expire at 11:59 p.m., Eastern time on a Tuesday, then the five (5) consecutive trading days would be the preceding Monday through Friday assuming each day prior to the Tuesday expiration date was a trading day (other than Saturday or Sunday).

We refer to this as the “offer consideration.”

The Offeror’s obligation to accept for exchange Maxwell shares validly tendered (and not validly withdrawn) pursuant to the offer is subject to the satisfaction or waiver by the Offeror of certain conditions, including the condition that, prior to the expiration of the offer, there have been validly tendered and not validly withdrawn a number of Maxwell shares that, upon the consummation of the offer, together with Maxwell shares then owned by Tesla and the Offeror (if any), would represent at least a majority of the aggregate voting power of the Maxwell shares outstanding immediately after the consummation of the offer (which we refer to as the “minimum tender condition”), as more fully described under the section entitled “The Offer—Conditions of the Offer.”

The offer is being made pursuant to an Agreement and Plan of Merger (which we refer to as the “merger agreement”), dated as of February 3, 2019, among Tesla, the Offeror and Maxwell. A copy of the merger agreement is attached to this document as Annex A.

The purpose of the offer is for Tesla to acquire control of, and ultimately the entire equity interest in, Maxwell. The offer is the first step in Tesla’s plan to acquire all of the outstanding Maxwell shares. If the offer is completed and as a second step in such plan, Tesla intends to promptly consummate a merger of the Offeror with and into Maxwell, with Maxwell surviving the merger (the “merger”), subject to the terms and conditions of the merger agreement. The purpose of the merger is for Tesla to acquire all Maxwell shares that it did not acquire in the offer. In the merger, each outstanding Maxwell share that was not acquired by Tesla or the Offeror will be converted into the right to receive the offer consideration. Upon the consummation of the merger, the Maxwell business will be held in a wholly-owned subsidiary of Tesla, and the former Maxwell stockholders will no longer have any direct ownership interest in the surviving corporation. If the offer is completed, the merger will be consummated pursuant to Section 251(h) of the General Corporation Law of the State of Delaware (the “DGCL”), and accordingly no stockholder vote will be required to complete the merger. The board of directors of Maxwell unanimously: (i) determined that the terms of the merger agreement and the transactions contemplated by the merger agreement, including the offer, the merger and the issuance of Tesla shares in connection therewith, are fair to, and in the best interests of, Maxwell and its stockholders; (ii) determined that it is in the best interests of Maxwell and its stockholders and declared it advisable to enter into the merger agreement; and (iii) approved the execution and delivery by Maxwell of the merger agreement, the performance by Maxwell of its covenants and agreements contained in the merger agreement and the consummation of the offer, the merger and the other transactions contemplated by the merger agreement upon the terms and subject to the conditions contained in the merger agreement. The board of directors of Maxwell has also resolved to recommend that the stockholders of Maxwell accept the offer and tender their shares of Maxwell common stock to the Offeror pursuant to the offer.

The Tesla board of directors also determined that the merger agreement and the transactions contemplated by the merger agreement, including the offer and the merger and the issuance of Tesla shares in the offer and merger, are advisable and fair to, and in the best interests of, Tesla and its stockholders, and approved the execution and delivery by Tesla of the merger agreement.

Tesla common stock is listed on the Nasdaq Global Select Market under the symbol “TSLA” and Maxwell common stock is listed on the Nasdaq Global Market under the symbol “MXWL”.

The offer and the merger, taken together, are intended to qualify as a reorganization for U.S. federal income tax purposes. Holders of Maxwell shares should read the section entitled “Material U.S. Federal Income Tax Consequences” for a more detailed discussion of certain U.S. federal income tax consequences of the offer and the merger to holders of Maxwell shares.

For a discussion of certain factors that Maxwell stockholders should consider in connection with the offer, please read the section of this document entitled “Risk Factors” beginning on page 24.

You are encouraged to read this entire document and the related letter of transmittal carefully, including the annexes and information referred to or incorporated by reference in this document.

Neither Tesla nor the Offeror has authorized any person to provide any information or to make any representation in connection with the offer other than the information contained or incorporated by reference in this document, and if any person provides any information or makes any representation of this kind, that information or representation must not be relied upon as having been authorized by Tesla or the Offeror.

Neither the U.S. Securities and Exchange Commission (the “SEC”) nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this document. Any representation to the contrary is a criminal offense.

The date of this preliminary prospectus/offer to exchange is April 29, 2019.

QUESTIONS AND ANSWERS ABOUT THE OFFER AND THE MERGER

Below are some of the questions that you as a holder of Maxwell shares may have regarding the offer and the merger and answers to those questions. You are urged to carefully read the remainder of this document and the related letter of transmittal and the other documents to which we have referred because the information contained in this section and in the “Summary” is not complete. Additional important information is contained in the remainder of this document and the related letter of transmittal. See the section entitled “Where to Obtain More Information.” As used in this document, unless otherwise indicated or the context requires, “Tesla” or “we” refers to Tesla, and its consolidated subsidiaries; the “Offeror” refers to Cambria Acquisition Corp., a direct wholly-owned subsidiary of Tesla; and “Maxwell” refers to Maxwell and its consolidated subsidiaries.

Who is offering to buy my Maxwell shares?

Tesla, through the Offeror, its direct wholly-owned subsidiary, is making this offer to exchange Tesla common stock for Maxwell shares. Tesla’s mission is to accelerate the world’s transition to sustainable energy. Tesla designs, develops, manufactures, leases and sells high-performance fully electric vehicles, solar energy generation systems and energy storage products. Tesla also offers maintenance, installation, operation and other services related to its products. Tesla’s production vehicle fleet includes its Model S premium sedan and its Model X sport utility vehicle, which are its highest-performance vehicles, and its Model 3, a lower priced sedan designed for the mass market. Tesla continues to enhance its vehicle offerings with enhanced Autopilot options, Internet connectivity and free over-the-air software updates to provide additional safety, convenience and performance features. In addition, Tesla also has several future electric vehicles in its product pipeline, including Model Y, Tesla Semi, a pickup truck and a new version of the Tesla Roadster. Tesla leases and sells retrofit solar energy systems and sells renewable energy and energy storage products to its customers, and is ramping its Solar Roof product that combines solar energy generation with attractive, integrated styling. Tesla’s energy storage products, which it manufactures at Gigafactory 1, consist of Powerwall, mostly for residential applications, and Powerpack, for commercial, industrial and utility-scale applications.

On February 3, 2019, Tesla, the Offeror and Maxwell entered into an Agreement and Plan of Merger (the “merger agreement”).

What are the classes and amounts of Maxwell securities that Tesla is offering to acquire?

Tesla is seeking to acquire all issued and outstanding shares of Maxwell common stock, par value $0.10 per share.

What will I receive for my Maxwell shares?

Tesla, through the Offeror, is offering to exchange each outstanding share of Maxwell common stock that has been validly tendered and not validly withdrawn in the offer for a fraction of a share of Tesla common stock, par value $0.001 per share, equal to the quotient obtained by dividing $4.75 by the volume weighted average of the daily volume weighted average of the trading price of one (1) share of Tesla common stock as reported on the Nasdaq Global Select Market for the five (5) consecutive trading days immediately preceding the second trading day prior to the date of the expiration of the offer (the “Tesla trading price”), subject to the minimum, plus cash in lieu of any fractional shares of Tesla common stock, without interest and less any applicable withholding taxes (referred to herein as the “offer consideration”). For the avoidance of doubt, if the offer were to expire at 11:59 p.m., Eastern time on a Tuesday, then the five (5) consecutive trading days would be the preceding Monday through Friday assuming each day prior to the Tuesday expiration date was a trading day (other than Saturday or Sunday). In the event that the Tesla common stock price is equal to or less than $245.90, the minimum will apply and each share of Maxwell common stock validly tendered and not validly withdrawn in the offer will be exchanged for 0.0193 of a share of Tesla common stock and may result in less than $4.75 in value. Accordingly, the actual number of shares and the value of Tesla common stock delivered to Maxwell will depend

2

on the Tesla stock price, and the value of the shares of Tesla common stock delivered for each such share of Maxwell common stock may be less than $4.75. If you do not tender your shares into the offer but the merger is completed (pursuant to Section 251(h) of the DGCL without a stockholder vote), you will also receive the offer consideration in exchange for your shares of Maxwell common stock.

What will happen to my Maxwell stock options?

Any option to purchase shares of Maxwell common stock granted under Maxwell’s 2005 Omnibus Equity Incentive Plan (the “2005 Plan”) or Maxwell’s 2013 Omnibus Equity Incentive Plan (the “2013 Plan”) that remains outstanding as of the effective time of the merger (the “effective time”) will be treated in accordance with the merger agreement.

Pursuant to the merger agreement, at the effective time, each Maxwell option that is outstanding, unexercised and unexpired as of immediately prior to the effective time (other than former service provider options (defined below)) shall be assumed by Tesla and converted into and become an option to acquire shares of Tesla common stock (each, an “adjusted option”), on the same terms and conditions as were applicable under the Maxwell option as of immediately prior to the effective time, except that: (x) the number of shares of Tesla common stock subject to the adjusted option as of the effective time will be determined by multiplying the number of shares of Maxwell common stock subject to the corresponding Maxwell option immediately prior to the effective time, by the offer consideration, with any fractional shares in the resulting product rounded down to the nearest whole share, and (y) the per share exercise price for each share of Tesla common stock that may be acquired upon exercise of the adjusted option as of the effective time will be determined by dividing the per share exercise price of the Maxwell option as in effect immediately prior to the effective time, by the offer consideration, with any fractional cent in the resulting quotient rounded up to the nearest whole cent. Each adjusted option otherwise shall be subject to the same terms and conditions applicable to the corresponding Maxwell option under the applicable Maxwell Equity Plan (defined below in the immediately following question and answer) and the agreements evidencing the Maxwell options thereunder, including vesting terms.

Each Maxwell option that (i) is outstanding, unexercised and unexpired as of immediately prior to the effective time, (ii) either is vested as of immediately prior to the effective time or by its terms accelerates vesting as a result of the merger and (iii) is held by a former service provider of Maxwell or any Maxwell subsidiary as of immediately prior to the effective time (each, a “former service provider option”) shall not be treated in the same manner. At the effective time, without any action on the part of Tesla, Maxwell or the holder of the former service provider option, each former service provider option shall be cancelled and converted into the right to receive a number of shares of Tesla common stock determined as: (i) (A) the number of shares of Maxwell common stock subject to the former service provider option immediately prior to the effective time, multiplied by (B) the offer consideration, minus (ii) (A) the aggregate exercise or purchase price for all shares of Maxwell common stock subject to such former service provider option divided by (B) the Tesla trading price, with any resulting fractional share rounded down to the nearest whole share.

See the section entitled “Merger Agreement—Treatment of Maxwell Equity Awards.”

What will happen to my Maxwell restricted stock units?

Any restricted stock unit award granted under the 2005 Plan and 2013 Plan (together, the “Maxwell Equity Plans”), whether vesting thereof is based on service, performance, stock performance or other conditions (each such restricted stock unit award and any Inducement RSUs, as defined further below, a “Maxwell RSU award”) that remains outstanding as of the effective time of the merger will be treated in accordance with the merger agreement.

At the effective time, each Maxwell RSU award (other than any former service provider RSUs (defined below)) that is outstanding immediately prior to the effective time, without any action on the part of Tesla, Maxwell or

3

the holder thereof, shall be assumed by Tesla and converted automatically into and become a restricted stock unit covering shares of Tesla common stock (each, an “adjusted RSU”), on the same terms and conditions as were applicable under the Maxwell RSU award as of immediately prior to the effective time, except that the number of shares of Tesla common stock subject to the adjusted RSU as of the effective time will be determined by multiplying the number of shares of Maxwell common stock subject to the corresponding Maxwell RSU award immediately prior to the effective time, by the offer consideration, with any fractional shares in the resulting product rounded down to the nearest whole share. Each adjusted RSU otherwise shall be subject to the same terms and conditions applicable to the corresponding Maxwell RSU award under the applicable Maxwell Equity Plan and any agreements evidencing the Maxwell RSU awards thereunder, including vesting terms.

Each Maxwell RSU award that (i) is outstanding, unexercised, and unexpired as of immediately prior to the effective time, (ii) either is vested as of immediately prior to the effective time or by its terms accelerates vesting as a result of the merger and (ii) is held by a former service provider of Maxwell or any Maxwell subsidiary as of immediately prior to the effective time (each, a “former service provider RSU, and together with a former service provider option, a “former service provider award”) shall not be treated in the same manner. At the effective time, without any action on the part of Tesla, Maxwell or the holder of the former service provider RSU, each former service provider RSU shall be cancelled and converted into the right to receive a number of shares of Tesla common stock determined as: (i) (A) the number of shares of Maxwell common stock subject to the former service provider RSU immediately prior to the effective time, multiplied by (B) the offer consideration, with any resulting fractional share rounded down to the nearest whole share.

See the section entitled “Merger Agreement—Treatment of Maxwell Equity Awards.”

What will happen to the Maxwell Employee Stock Purchase Plan?

Maxwell shall take all actions with respect to the Maxwell 2004 Employee Stock Purchase Plan (the “ESPP”) that are necessary to provide that: (i) with respect to any offering periods in effect as of February 3, 2019 (the “Current ESPP Offering Period”), no employee who is not a participant in the ESPP as of the date hereof may become a participant in the ESPP and no participant may increase his or her contributions or payroll deductions under the ESPP after the date hereof; (ii) subject to the consummation of the merger, the ESPP shall terminate effective immediately prior to the effective time; (iii) if the Current ESPP Offering Period terminates prior to the effective time, then the ESPP shall be suspended and no new offering period shall be commenced under the ESPP prior to the termination of the merger agreement; and (iv) if any Current ESPP Offering Period is still in effect at the effective time, then the last day of such Current ESPP Offering Period shall be accelerated to a date before the effective date as specified by the Maxwell board of directors or its designated committee.

See the section entitled “Merger Agreement—Treatment of Maxwell Equity Awards.”

Will I have to pay any fee or commission to exchange my shares of Maxwell common stock?

If you are the record owner of your shares of Maxwell common stock and you tender these shares in the offer, you will not have to pay any brokerage fees, commissions or similar expenses. If you own your shares of Maxwell common stock through a broker, dealer, commercial bank, trust company or other nominee and your broker, dealer, commercial bank, trust company or other nominee tenders your Maxwell shares on your behalf, your broker or such other nominee may charge a fee for doing so. You should consult your broker, dealer, commercial bank, trust company or other nominee to determine whether any charges will apply.

Why is Tesla making this offer?

The purpose of the offer is for Tesla to acquire control of, and ultimately the entire equity interest in, Maxwell. The offer is the first step in Tesla’s plan to acquire all of the outstanding Maxwell shares, and the merger is the second step in such plan.

4

In the offer, if a sufficient number of Maxwell shares are tendered into the offer prior to the expiration time of the offer such that Tesla and the Offeror will own at least a majority of the aggregate voting power of the Maxwell shares outstanding immediately after the consummation of the offer, subject to the satisfaction or waiver of the other conditions to the offer, Tesla and the Offeror will accept for exchange, and exchange, the shares tendered in the offer. Then, thereafter and as the second step in Tesla’s plan to acquire all of the outstanding Maxwell shares, Tesla intends to promptly consummate a merger of the Offeror with and into Maxwell, with Maxwell surviving the merger (the “merger”), subject to the terms and conditions of the merger agreement. The purpose of the merger is for Tesla to acquire all remaining Maxwell shares that it did not acquire in the offer. Upon consummation of the merger, the Maxwell business will be held in a wholly-owned subsidiary of Tesla, and the former stockholders of Maxwell will no longer have any direct ownership interest in the surviving corporation. If the offer is completed, the merger will be consummated pursuant to Section 251(h) of the DGCL, and accordingly no stockholder vote will be required to consummate the merger.

What does the Maxwell board of directors recommend?

The board of directors of Maxwell unanimously: (i) determined that the terms of the merger agreement and the transactions contemplated by the merger agreement, including the offer, the merger and the issuance of Tesla shares in connection therewith, are fair to, and in the best interests of, Maxwell and its stockholders; (ii) determined that it is in the best interests of Maxwell and its stockholders and declared it advisable to enter into the merger agreement; and (iii) approved the execution and delivery by Maxwell of the merger agreement, the performance by Maxwell of its covenants and agreements contained in the merger agreement and the consummation of the offer, the merger and the other transactions contemplated by the merger agreement upon the terms and subject to the conditions contained in the merger agreement. The board of directors of Maxwell has also resolved to recommend that the stockholders of Maxwell accept the offer and tender their shares of Maxwell common stock to the Offeror pursuant to the offer.

See the section entitled “The Offer—Maxwell’s Reasons for the Offer and the Merger; Recommendation of the Maxwell Board of Directors” for more information. A description of the reasons for this recommendation is also set forth in Maxwell’s Solicitation/Recommendation Statement on Schedule 14D-9 (the “Schedule 14D-9”), which has been filed with the U.S. Securities and Exchange Commission (the “SEC”) and is being mailed to you and other stockholders of Maxwell together with this document.

What are the most significant conditions of the offer?

The offer is conditioned upon, among other things, the following:

5

The offer is subject to certain other conditions set forth below in the section entitled “The Offer—Conditions of the Offer.” The conditions to the offer are for the sole benefit of Tesla and the Offeror and may be asserted by Tesla or the Offeror regardless of the circumstances giving rise to any such condition or may be waived by Tesla or the Offeror, by express and specific action to that effect, in whole or in part at any time and from time to time, in each case, prior to the expiration of the offer. However, certain specified conditions (including all the conditions noted above other than the conditions related to a material adverse effect of Maxwell, accuracy of Maxwell’s representations and Maxwell’s compliance with covenants) may not be waived by Tesla or the Offeror without the consent of Maxwell (which may be granted or withheld in its sole discretion). There is no financing condition to the offer.

How long will it take to complete the proposed transaction?

The transaction is expected to be completed in the second quarter of Tesla’s fiscal year 2019, ending June 30, 2019, subject to the satisfaction or waiver of the conditions described in the sections entitled “The Offer—Conditions of the Offer” and “Merger Agreement—Conditions of the Merger.”

How long do I have to decide whether to tender my Maxwell shares in the offer?

The offer is scheduled to expire at 11:59 p.m., Eastern time, at the end of May 15, 2019, unless extended or terminated in accordance with the merger agreement. Any extension, delay, termination, waiver or amendment of the offer will be followed as promptly as practicable by public announcement thereof to be made no later than 9:00 a.m., Eastern time, on the next business day after the previously scheduled expiration date. During any such extension, all Maxwell shares previously tendered and not validly withdrawn will remain subject to the offer, subject to the rights of a tendering stockholder to withdraw such stockholder’s shares. “Expiration date” means 11:59 p.m., Eastern time, at the end of May 15, 2019, unless and until the Offeror has extended the period during which the offer is open, subject to the terms and conditions of the merger agreement, in which event the term “expiration date” means the latest time and date at which the offer, as so extended by the Offeror, will expire.

Under the merger agreement, unless Maxwell consents otherwise (which may be granted or withheld in its sole discretion) or the merger agreement is terminated:

6

The Offeror is not required to extend the offer beyond July 3, 2019, which we refer to as the “outside date.”

Upon the terms and subject to the satisfaction or waiver of the conditions of the offer (including, if the offer is extended or amended, the terms and conditions of any extension or amendment), promptly after the expiration of the offer, the Offeror will accept for payment, and will pay for, all Maxwell shares validly tendered and not validly withdrawn prior to the expiration of the offer.

Any decision to extend the offer will be made public by an announcement regarding such extension as described under the section entitled “The Offer—Extension, Termination and Amendment of Offer.”

How do I tender my Maxwell shares?

To validly tender your Maxwell shares represented by physical certificates into the offer, stockholders must deliver the certificates representing such shares, together with a properly completed and duly executed letter of transmittal, along with any required signature guarantees and any other required documents for Maxwell shares, to Computershare Trust Company, N.A., the depositary and exchange agent (the “exchange agent”) for the offer and the merger, not later than the expiration date. The letter of transmittal is enclosed with this document.

To validly tender Maxwell shares in electronic book-entry form, Maxwell stockholders must deliver an agent’s message in connection with a book-entry transfer and any other required documents for tendered Maxwell shares to the exchange agent, not later than the expiration date.

If your shares of Maxwell common stock are held in “street name” (i.e., through a broker, dealer, commercial bank, trust company or other nominee), these shares of Maxwell common stock may be tendered by your nominee by book-entry transfer through The Depository Trust Company. To validly tender such shares held in street name, Maxwell stockholders should instruct such nominee to do so prior to the expiration of the offer.

We are not providing for guaranteed delivery procedures and therefore you must allow sufficient time for the necessary tender procedures to be completed during normal business hours of The Depository Trust Company

7

prior to the expiration date. Tenders received by the exchange agent after the expiration date will be disregarded and of no effect. In all cases, you will receive your consideration for your tendered Maxwell shares only after timely receipt by the exchange agent of certificates for such Maxwell shares (or of a confirmation of a book-entry transfer of such shares) and a properly completed and duly executed letter of transmittal, together with any other required documents.

For a complete discussion of the procedures for tendering your Maxwell shares, see the section entitled “The Offer—Procedure for Tendering.”

Until what time can I withdraw tendered Maxwell shares?

You may withdraw your previously tendered Maxwell shares at any time until the offer has expired and, if the Offeror has not accepted your Maxwell shares for payment by May 15, 2019, you may withdraw them at any time on or after that date until the Offeror accepts shares for payment. If you validly withdraw your previously tendered Maxwell shares, you will receive shares of the same class of Maxwell common stock that you tendered. Once the Offeror accepts your tendered Maxwell shares for payment upon or after expiration of the offer, however, you will no longer be able to withdraw them. For a complete discussion of the procedures for withdrawing your Maxwell shares, see the section entitled “The Offer—Withdrawal Rights.”

How do I withdraw previously tendered Maxwell shares?

To withdraw previously tendered Maxwell shares, you must deliver a written notice of withdrawal with the required information to the exchange agent at any time at which you have the right to withdraw shares. If you tendered Maxwell shares by giving instructions to a broker, dealer, commercial bank, trust company or other nominee, you must instruct such broker, dealer, commercial bank, trust company or other nominee to arrange for the withdrawal of your Maxwell shares and such broker, dealer, commercial bank, trust company or other nominee must effectively withdraw such Maxwell shares at any time at which you have the right to withdraw shares. If you validly withdraw your previously tendered Maxwell shares, you will receive shares of the same class of Maxwell common stock that you tendered. For a discussion of the procedures for withdrawing your Maxwell shares, including the applicable deadlines for effecting withdrawals, see the section entitled “The Offer—Withdrawal Rights.”

When and how will I receive the offer consideration in exchange for my tendered Maxwell shares?

The Offeror will exchange all validly tendered and not validly withdrawn Maxwell shares promptly after the expiration date of the offer, subject to the terms thereof and the satisfaction or waiver of the conditions to the offer, as set forth in the section entitled “The Offer—Conditions of the Offer.” The Offeror will deliver the consideration for your validly tendered and not validly withdrawn shares through the exchange agent, which will act as your agent for the purpose of receiving the offer consideration from the Offeror and transmitting such consideration to you. In all cases, you will receive your consideration for your tendered Maxwell shares only after timely receipt by the exchange agent of certificates for such Maxwell shares (or of a confirmation of a book-entry transfer of such shares) (as described in the section entitled “The Offer—Procedure for Tendering”) and a properly completed and duly executed letter of transmittal, together with any other required documents.

Why does the cover page to this document state that this offer is preliminary and subject to change, and that the registration statement filed with the SEC is not yet effective? Does this mean that the offer has not commenced?

No. Completion of this document and effectiveness of the registration statement are not necessary to commence this offer. The offer was commenced on the date of the initial filing of the registration statement on Form S-4 of which this document is a part. Tesla and the Offeror cannot, however, accept for exchange any Maxwell shares tendered in the offer or exchange any shares until the registration statement is declared effective by the SEC and the other conditions to the offer have been satisfied or waived (subject to the terms and conditions of the merger agreement).

What happens if I do not tender my Maxwell shares?

If, after consummation of the offer, Tesla and the Offeror own a majority of the aggregate voting power of the outstanding Maxwell shares, Tesla intends to promptly complete the merger after the consummation of the offer, subject to the terms and conditions of the merger agreement.

Upon consummation of the merger, each Maxwell share that has not been tendered and accepted for exchange in the offer will be converted in the merger into the right to receive the offer consideration. See the section entitled “Merger Agreement—Exchange of Maxwell Certificates or Book-Entry Shares for the Offer Consideration.”

Does Tesla have the financial resources to complete the offer and the merger?

Yes. The offer consideration will consist of Tesla shares. Tesla will pay cash for any fractional shares from cash on-hand and currently available to Tesla. The offer and the merger are not conditioned upon any financing arrangements or contingencies.

If the offer is completed, will Maxwell continue as a public company?

No. Tesla is required, on the terms and subject to the satisfaction or waiver of the conditions set forth in the merger agreement, to consummate the merger promptly following the acceptance of Maxwell shares in the offer. If the merger takes place, Maxwell will no longer be publicly traded. Even if for some reason the merger does not take place, if Tesla and the Offeror purchase all Maxwell shares validly tendered and not validly withdrawn, there may be so few remaining stockholders and publicly held shares that Maxwell shares will no longer be eligible to be traded through the Nasdaq Global Market or other securities exchanges, there may not be an active public trading market for Maxwell shares and Maxwell may no longer be required to make filings with the SEC or otherwise comply with the SEC rules relating to publicly held companies.

Will the offer be followed by a merger if all Maxwell shares are not tendered in the offer?

Yes, unless the conditions to the merger are not satisfied or waived in accordance with the merger agreement. If the Offeror accepts for payment all Maxwell shares validly tendered and not validly withdrawn pursuant to the offer, and the other conditions to the merger are satisfied or waived in accordance with the merger agreement, the merger will take place promptly thereafter. If the merger takes place, Tesla will own 100% of the equity of Maxwell, and all of the remaining Maxwell stockholders, will have the right to receive the offer consideration.

Since the merger will be governed by Section 251(h) of the DGCL, no stockholder vote will be required to consummate the merger in the event that the offer is consummated. Tesla is required, on the terms and subject to the satisfaction or waiver of the conditions set forth in the merger agreement, to consummate the merger as promptly as practicable following the consummation of the offer. As such, Tesla does not expect there to be a significant period of time between the consummation of the offer and the consummation of the merger.

Have any stockholders of Maxwell already agreed to tender their shares in the Offer?

Yes, concurrently with the execution of the merger agreement, on February 3, 2019, (i) Maxwell board members Richard Bergman, Steven Bilodeau, Jörg Buchheim, Franz Fink, Burkhard Göschel, Ilya Golubovich, John Mutch and I2BF Energy Limited and (ii) Maxwell officers Franz Fink, David Lyle and Emily Lough ((i)-(ii) collectively the “supporting stockholders”) entered into a tender and support agreements with Tesla and the Offeror (the “support agreement”). Subject to the terms and conditions of the support agreement, the supporting stockholders agreed, among other things, to:

9

The support agreement terminates upon certain events, including the termination of the merger agreement in accordance with its terms.

The shares of Maxwell common stock subject to the support agreement represent approximately 7.65% of the shares of Maxwell common stock outstanding as of February 3, 2019.

For more information regarding the support agreement, see the section entitled “Other Transaction Agreements—Support Agreement,” and the support agreement, which is filed as Exhibit 99.6 to this document.

Do the officers and directors of Maxwell have interests in the offer and the merger that are different from stockholders generally?

You should be aware that some of the officers and directors of Maxwell may be deemed to have interests in the offer and the merger that are different from, or in addition to, your interests as a Maxwell stockholder. These interests may include, among others, Maxwell option agreements and Maxwell RSU award agreements that certain officers and directors have entered into with Maxwell under the applicable Maxwell Equity Plan that provide for vesting acceleration in connection with the completion of the merger, agreements that certain officers have entered into with Maxwell that provide for the vesting acceleration of Maxwell options and Maxwell RSU awards in the event the executive officer experiences a qualifying termination of employment within a specified period in connection with a change in control of Maxwell, payments of severance benefits to certain officers under Maxwell’s Severance and Change in Control Plan or pursuant to employment agreements that certain officers have entered into with Maxwell, and certain indemnification obligations. See the sections entitled “The Offer—Interests of Certain Persons in the Offer and the Merger” and “Merger Agreement—Employee Matters” below for more information.

As of February 11, 2019, the directors and executive officers of Maxwell and their affiliates beneficially owned approximately 3,897,048 Maxwell shares, representing approximately 8.41% of the aggregate voting power of the Maxwell shares outstanding as of February 11, 2019.

Concurrently with the execution of the merger agreement, on February 3, 2019, (i) Maxwell board members Richard Bergman, Steven Bilodeau, Jörg Buchheim, Franz Fink, Burkhard Göschel, Ilya Golubovich, John Mutch and I2BF Energy Limited and (ii) Maxwell officers Franz Fink, David Lyle and Emily Lough, entered into a tender and support agreement with Tesla and the Offeror, solely in their capacities as stockholders of Maxwell. For more information regarding the support agreement, see the section entitled “Other Transaction Agreements—Support Agreement,” and such support agreement, which is filed as Exhibit 99.6 to this document.

See also the section entitled “Item 3—Past Contacts, Transactions, Negotiations and Agreements” in the Schedule 14D-9, which has been filed with the SEC and is being mailed to you and other stockholders of Maxwell together with this document.

What are the U.S. federal income tax consequences of receiving Tesla stock in exchange for my Maxwell shares in the offer or the merger?

Each of Tesla and Maxwell intends the offer and the merger, taken together, to qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”). However, completion of the offer and the merger is not conditioned upon receipt of an opinion from counsel that the offer and the merger qualify as a reorganization, and the offer and merger will occur even if they do not so qualify.

10

Assuming the offer and the merger, taken together, qualify as a reorganization, in general, the material U.S. federal income tax consequences to U.S. Holders (as defined herein) of Maxwell shares are expected to be as follows:

Tax matters are very complicated, and the tax consequences of the offer and merger to a particular Maxwell stockholder will depend on such stockholder’s circumstances. Accordingly, you should consult your tax advisor for a full understanding of the tax consequences of the offer and merger to you, including the applicability and effect of U.S. federal, state, local and non-U.S. income and other tax laws. For more information, please see the section entitled “Material U.S. Federal Income Tax Consequences” beginning on page 127.

RISK FACTORS

Maxwell stockholders should carefully read this document and the other documents referred to or incorporated by reference into this document, including in particular the following risk factors, in deciding whether to tender Maxwell shares pursuant to the offer.

Risk Factors Relating to the Offer and the Merger

The offer remains subject to conditions that Tesla cannot control.

The offer is subject to conditions, including the minimum tender condition, receipt of required regulatory approvals, lack of legal prohibitions, no material adverse effect (as described in the section entitled “Merger Agreement—Material Adverse Effect”) having occurred with respect to Maxwell since the date of the merger agreement that is continuing as of immediately prior to the expiration of the offer, the accuracy of Maxwell’s representations and warranties made in the merger agreement (subject to specified materiality standards), Maxwell being in compliance in all material respects with its covenants under the merger agreement, the listing of the Tesla shares to be issued in the offer and the merger being authorized for listing on the Nasdaq Global Select Market, subject to official notice of issuance, the registration statement on Form S-4 of which this document is a part becoming effective, and the merger agreement not having been terminated in accordance with its terms. There are no assurances that all of the conditions to the offer will be satisfied or that the conditions will be satisfied in the time frame expected. If the conditions to the offer are not met, then Tesla may, subject to the terms and conditions of the merger agreement, allow the offer to expire, or amend or extend the offer. See the section entitled “The Offer—Conditions of the Offer” for a discussion of the conditions to the offer.

The value of the Tesla common stock issuable in the offer and the merger is subject to change based on fluctuations in the value of Tesla common stock, and Maxwell’s stockholders may, in certain circumstances, receive stock consideration with a value that, is less than $4.75 per share of Maxwell common stock.

The market value of Tesla common stock will fluctuate during the offer period as well as thereafter. The consideration issuable in the offer and the merger is calculated by reference to the volume weighted average of the daily volume weighted average of the trading price of one (1) share of Tesla common stock as reported on the Nasdaq Global Select Market for the five (5) consecutive trading days immediately preceding the second trading day prior to the date of the expiration of the offer (as adjusted as appropriate to reflect any stock splits, stock dividends, combinations, reorganizations, reclassifications or similar events) and subject to a minimum as described below. For the avoidance of doubt, if the offer were to expire at 11:59 p.m., Eastern time on a Tuesday, then the five (5) consecutive trading days would be the preceding Monday through Friday assuming each day prior to the Tuesday expiration date was a trading day (other than Saturday or Sunday). If the Tesla common stock price is greater than $245.90, the exchange ratio will be equal to the quotient obtained by dividing (1) $4.75 by (2) the Tesla trading price as calculated above. However, if the Tesla common stock price is equal to or less than $245.90, the minimum will apply and the exchange ratio will be fixed at 0.0193 and may result in less than $4.75 in value. Accordingly, the actual number of shares and the value of Tesla common stock delivered to participating Maxwell stockholders will depend on the Tesla stock price, and the value of the shares of Tesla common stock delivered for each such share of Maxwell common stock may be less than $4.75.

It is impossible to accurately predict the market price of Tesla common stock at the completion of the merger or during the 5-trading day period over which the Tesla common stock price is calculated and, therefore, impossible to accurately predict the number or value of the shares of Tesla common stock that Maxwell stockholders will receive in the merger. The market price for Tesla common stock may fluctuate both prior to completion of the merger and thereafter for a variety of reasons, including, among others, general market and economic conditions, the demand for Tesla’s or Maxwell’s products and services, changes in laws and regulations, other changes in Tesla’s and Maxwell’s respective businesses, operations, prospects and financial results of operations, market assessments of the likelihood that the merger will be completed, and the expected timing of the merger. Many of these factors are beyond Tesla’s and Maxwell’s control.

24

If the transactions are completed, Maxwell stockholders will receive Tesla shares as part of the offer consideration and will accordingly become Tesla stockholders. Tesla common stock may be affected by different factors than Maxwell common stock, and Tesla stockholders will have different rights than Maxwell stockholders.

Upon consummation of the transactions, Maxwell stockholders will receive Tesla shares and will accordingly become Tesla stockholders. Tesla’s business differs from that of Maxwell, and Tesla’s results of operations and stock price may be adversely affected by factors different from those that would affect Maxwell’s results of operations and stock price.

In addition, holders of shares of Tesla common stock will have rights as Tesla stockholders that differ from the rights they had as Maxwell stockholders before the transactions. For a comparison of the rights of Tesla stockholders to the rights of Maxwell stockholders, see the section entitled “Comparison of Stockholders’ Rights.”

Maxwell stockholders who participate in the offer will be forfeiting all rights with respect to their Maxwell shares other than the right to receive the offer consideration, including the right to participate directly in any earnings or future growth of Maxwell.

If the offer and the merger are completed, Maxwell stockholders will cease to have any equity interest in Maxwell and will not participate in its earnings or any future growth, except indirectly through ownership of Tesla shares received in the offer and the merger.

Consummation of the offer may adversely affect the liquidity of the Maxwell shares not tendered in the offer.

If the offer is completed, you should expect the number of Maxwell stockholders and the number of publicly-traded Maxwell shares to be significantly reduced. As a result, the closing of the offer can be expected to adversely affect, in a material way, the liquidity of the remaining Maxwell shares held by the public pending the consummation of the merger. While Tesla currently expects the merger to occur on the day after the offer is completed, Tesla cannot assure you that all conditions to the merger will be satisfied at that time or at all.

Maxwell directors and officers potentially have interests in the transaction that differ from, or are in addition to the interests of the Maxwell stockholders generally.

You should be aware that some of the officers and directors of Maxwell may be deemed to have interests in the offer and the merger that are different from, or in addition to, your interests as a Maxwell stockholder. These interests may include, among others, agreements that certain officers have entered into with Maxwell that provide for the acceleration of stock options and restricted stock units in the event the officer experiences a qualifying termination of employment within 12 months following a change of control of Maxwell, payments of severance benefits under Maxwell’s broad-based severance plan to executive officers and certain indemnification obligations. See the sections entitled “The Offer—Interests of Certain Persons in the Offer and the Merger” and “Merger Agreement—Employee Matters” below for more information.

As of February 11, 2019, the directors and executive officers of Maxwell and their affiliates beneficially owned approximately 3,897,048 Maxwell shares, representing approximately 8.41% of the aggregate voting power of the Maxwell shares outstanding as of February 11, 2019.

Concurrently with the execution of the merger agreement, on February 3, 2019, (i) Maxwell board members Richard Bergman, Steven Bilodeau, Jörg Buchheim, Franz Fink, Burkhard Göschel, Ilya Golubovich, John Mutch and I2BF Energy Limited and (ii) Maxwell officers Franz Fink, David Lyle and Emily Lough, entered into a tender and support agreement with Tesla and the Offeror, solely in their capacities as stockholders of Maxwell. For more information regarding the support agreement, see the section entitled “Other Transaction Agreements—Support Agreement,” and such support agreement, which is filed as Exhibit 99.6 to this document.

25

Maxwell stockholders will have a reduced ownership and voting interest in Tesla as compared to their ownership and voting interest in Maxwell.

After consummation of the offer and merger, Maxwell stockholders will own approximately 0.51% of the outstanding Tesla shares, based upon the number of outstanding Maxwell shares as of April 26, 2019, disregarding stock options, restricted stock units and other rights to acquire shares that may be issued by Tesla or Maxwell pursuant to any employee stock plan. Consequently, former Maxwell stockholders will have less influence on the management and policies of the combined company than they currently exercise over Maxwell.

Sales of substantial amounts of Tesla shares in the open market by former Maxwell stockholders could depress its stock price.

Other than shares held by persons who will be affiliates of Tesla after the offer and the merger, Tesla shares that are issued to Maxwell stockholders, including those shares issued upon the exercise of outstanding stock options or restricted stock units, will be freely tradable without restrictions or further registration under the Securities Act. If the offer and the merger are completed and if former Maxwell stockholders and Maxwell employees sell substantial amounts of Tesla common stock in the public market following consummation of the offer and the merger, the market price of Tesla common stock may decrease.

Litigation relating to the offer or the merger could require Tesla to incur significant costs and suffer management distraction, as well as could delay and/or enjoin the merger.

In connection with the merger agreement and the transactions contemplated thereby, nine purported class action lawsuits have been filed. Five complaints, captioned Kip Leggett v. Maxwell Technologies, Inc., et al., Case No. 3:19-cv-00377 (filed February 26, 2019), Shiva Stein v. Maxwell Technologies, Inc., et al., Case No. 3:19-cv-00395 (filed February 26, 2019), Joel Rosenfeld IRA v. Maxwell Technologies, Inc., et al., Case No. 3:19-cv-00413 (filed March 1, 2019), Franck Prissert v. Maxwell Technologies, Inc., et al., Case No. 3:19-cv-00429 (filed March 4, 2019) and Jonathan Mantak v. Maxwell Technologies, Inc., et. al., Case No. 3:19-cv-00451 (filed March 7, 2019) were filed in the United States District Court for the Southern District of California. Two complaints, captioned John Solak v. Maxwell Technologies, Inc., et al., Case No. 1:19-cv-00448 (filed March 4, 2019) and Sabatini v. Maxwell Technologies, Inc., et al., Case No. 1:19-cv-00443 (filed March 1, 2019), were filed in the United States District Court District of Delaware. One complaint, captioned Davis Rodden v. Steven Bilodeau, et al., Case No. 2019-0176 (filed March 4, 2019), was filed in the Delaware Chancery Court and was voluntarily dismissed on April 3, 2019. One complaint, captioned Jack Phillipps v. Maxwell Technologies, Inc., et al., Case No. 1:19-cv-01927 (filed February 28, 2019), was filed in the United States District Court for the Southern District of New York.

In general, the complaints assert claims against Maxwell and the Maxwell board of directors, with Tesla and the Offeror as additional defendants in the Kip Leggett v. Maxwell Technologies, Inc., et al., Sabatini v. Maxwell Technologies, Inc. et al., and John Solak v. Maxwell Technologies, Inc., et al. complaints. The complaints allege, among other things, that the defendants failed to make adequate disclosures in the Schedule 14D-9 filed by Maxwell on February 20, 2019. The complaints seek, among other things, to enjoin the proposed transaction, rescission of the proposed transaction should it be completed, and other equitable relief. Tesla and Maxwell believe the respective allegations in these complaints lack merit, and Tesla and Maxwell intend to vigorously defend the actions.

Tesla and Maxwell could be subject to additional demands or litigation related to the offer and the merger. Such actions may create uncertainty relating to the offer and the merger, and responding to such demands and defending such actions may be costly and distracting to management.

If the offer and the merger do not qualify as a tax-free reorganization, the receipt of Tesla common stock pursuant to the offer or merger could be fully taxable to all Maxwell stockholders.

Each of Tesla and Maxwell intends the merger to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. However, completion of the offer and merger are not conditioned upon receipt of an

26

opinion from counsel dated as of the closing date that the offer and merger, taken together, qualify as a reorganization. The tax opinions received by Tesla and Maxwell as of the effective date of the registration statement are based on representation letters delivered as of such date by Tesla, the Offeror and Maxwell pertaining to factual matters and on certain factual assumptions. If any of these assumptions or representations proves incorrect, for example, if there is a change in applicable law, the offer and the merger could be fully taxable to all Maxwell stockholders. See the section entitled “Material U.S. Federal Income Tax Consequences” beginning on page 127. Maxwell stockholders should consult their tax advisors to determine the specific tax consequences to them of the transactions contemplated by the merger agreement, including any federal, state, local, foreign or other tax consequences, and any tax return filing or other reporting requirements.

Risk Factors Relating to Tesla and the Combined Company

Tesla may fail to realize all of the anticipated benefits of the offer and the merger or those benefits may take longer to realize than expected.

Tesla believes there are benefits that may be realized through leveraging the products and technology of Maxwell. However, the efforts to realize these benefits and synergies will be a complex process and may disrupt both companies’ existing operations if not implemented in a timely and efficient manner. The full benefits of the transaction may not be realized as expected or may not be achieved within the anticipated time frame, or at all. Failure to achieve the anticipated benefits of the transactions could adversely affect Tesla’s results of operations or cash flows, cause dilution to the earnings per share of Tesla, decrease or delay any accretive effect of the transactions and negatively impact the price of Tesla common stock.

In addition, Tesla and Maxwell will be required to devote attention and resources prior to closing to prepare for the post-closing integration and operation of the combined company, and Tesla will be required post-closing to devote attention and resources to successfully align the business practices and operations of Tesla and Maxwell. This process may disrupt the businesses and, if ineffective, would limit the anticipated benefits of the transactions.

Tesla and Maxwell will incur direct and indirect costs as a result of the offer and the merger.

Tesla and Maxwell will incur expenses in connection with and as a result of completing the offer and the merger and, following the completion of the merger, Tesla expects to incur additional expenses in connection with combining the businesses and operations of Tesla and Maxwell. Factors beyond Tesla’s control could affect the total amount or timing of these expenses, many of which, by their nature, are difficult to estimate accurately. Moreover, diversion of management focus and resources from the day-to-day operation of the business to matters relating to the transactions could adversely affect each company’s business, regardless of whether the offer and the merger are completed.

Risks Related to Tesla’s Business

You should read and consider the risk factors specific to Tesla’s business that will also affect the combined company after the offer and the merger. These risks are described in Tesla’s Quarterly Report on Form 10-Q for the three months ended March 31, 2019, which is incorporated by reference into this document, and in other documents that are incorporated by reference into this document. See the section entitled “Where to Obtain More Information” for the location of information incorporated by reference in this document.

Risks Related to Maxwell’s Business

You should read and consider the risk factors specific to Maxwell’s business that will also affect the combined company after the offer and the merger. These risks are described in Maxwell’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018, which is incorporated by reference into this document, and in other documents that are incorporated by reference into this document. See the section entitled “Where to Obtain More Information” for the location of information incorporated by reference in this document.

THE OFFER

General

Tesla, through the Offeror, which is a direct wholly-owned subsidiary of Tesla is offering, upon the terms and subject to the conditions set forth in this document and in the accompanying letter of transmittal, to exchange each outstanding share of Maxwell common stock that has been validly tendered and not validly withdrawn in the offer for a fraction of a share of Tesla common stock equal to the quotient obtained by dividing $4.75 by the volume weighted average of the daily volume weighted average of the trading price of one (1) share of Tesla common stock as reported on the Nasdaq Global Select Market for the five (5) consecutive trading days immediately preceding the second trading day prior to the date of the expiration of the offer (the “Tesla trading price”), subject to the minimum. For the avoidance of doubt, if the offer were to expire at 11:59 p.m., Eastern time on a Tuesday, then the five (5) consecutive trading days would be the preceding Monday through Friday assuming each day prior to the Tuesday expiration date was a trading day (other than Saturday or Sunday). In the event that the Tesla trading price is equal to or less than $245.90, the minimum will apply and the exchange ratio will be fixed at 0.0193. Such shares of Tesla common stock plus cash in lieu of any fractional shares of Tesla common stock is referred to herein as the “offer consideration,” and the offer consideration will be paid without interest and less any applicable withholding taxes.

Maxwell stockholders will not receive any fractional shares of Tesla common stock in the offer or the merger, and each Maxwell stockholder who otherwise would be entitled to receive a fraction of a share of Tesla common stock pursuant to the offer or the merger will be paid an amount in cash (without interest) equal to such fractional part of a share of Tesla common stock multiplied by the volume weighted average of the daily volume weighted average of the trading price of one (1) share of Tesla common stock as reported on the Nasdaq Global Select Market for the five (5) consecutive trading days ending on and including the second trading day immediately preceding the expiration of the offer. See the section entitled “Merger Agreement—Fractional Shares.”

The purpose of the offer is for Tesla to acquire control of, and ultimately the entire equity interest in, Maxwell. The offer is the first step in Tesla’s plan to acquire all of the outstanding Maxwell shares, and the merger is the second step in such plan. If the offer is completed, validly tendered (and not validly withdrawn) Maxwell shares will be exchanged for the offer consideration, and if the merger is completed, any remaining Maxwell shares that were not tendered into the offer will be converted into the right to receive the offer consideration. If the offer is completed, Tesla intends to promptly consummate the merger as the second step in such plan, subject to the terms and conditions of the merger agreement. The purpose of the merger is for Tesla to acquire all Maxwell shares that it did not acquire in the offer. Upon consummation of the merger, the Maxwell business will be held in a wholly-owned subsidiary of Tesla, and the former Maxwell stockholders will no longer have any direct ownership interest in the surviving corporation.

Background of the Offer and the Merger

The Schedule 14D-9 includes additional information on the background, deliberations and other activities involving Maxwell (see the section entitled “Background of the Offer and the Merger” in the Schedule 14 D-9, which has been filed with the SEC and is being mailed to you and other stockholders of Maxwell together with this document). You are encouraged to read that section in its entirety.

Over the past several years, Tesla and Maxwell have had periodic commercial related discussions in connection with potential opportunities between the two companies. In mid-2018, Tesla and Maxwell began a series of discussions in connection with a potential strategic commercial relationship. As part of their discussions regarding a potential strategic commercial relationship, Dr. Franz Fink, the President and Chief Executive Officer, and other representatives of Maxwell, on the one hand, and representatives of Tesla, on the other hand, have had discussions from time to time to better understand each other’s respective businesses, platforms and products, and to explore various ways in which they could collaborate in order to advance their shared business

30

objectives. These discussions were related to commercial transactions and, at this time, did not involve discussions related to a potential acquisition of Maxwell by Tesla. No commercial agreement was entered into between the parties, and Maxwell never received any revenue from Tesla related to any commercial arrangements.

On December 12, 2018, Brian Scelfo of Tesla contacted Dr. Fink to convey Tesla’s interest in a potential acquisition of Maxwell rather than pursuing a strategic commercial relationship. Prior to December 12, 2018, none of the discussions between representatives of Maxwell and Tesla involved the possibility of an acquisition of Maxwell. Mr. Scelfo explained to Dr. Fink Tesla’s strategic rationale for a potential acquisition of Maxwell. Dr. Fink informed Mr. Scelfo that while Maxwell was not actively looking to sell the company, he would inform the Maxwell board of directors of Tesla’s current interest in a potential acquisition of Maxwell.

On December 13, 2018, Dr. Fink received a call from Mr. Scelfo, who called Dr. Fink as a follow up to his December 12 call, to express Tesla’s interest in conducting due diligence for a potential transaction. Following the call, Mr. Scelfo sent a mutual nondisclosure agreement to Dr. Fink so the parties could begin discussions and for preliminary diligence in connection with a potential transaction. On December 14, 2018, Tesla and Maxwell entered into the mutual nondisclosure agreement related to a possible negotiated transaction between Tesla and Maxwell.

On December 14, 2018, Tesla delivered a non-binding letter of intent to Dr. Fink proposing to acquire 100% of the outstanding shares of capital stock of Maxwell for a per share purchase price of $2.35, which represented a premium of 15.2% from the closing price of Maxwell’s stock on December 14, 2018. The purchase price would be paid in shares of Tesla stock based on an exchange ratio to be fixed at the time of signing definitive transaction documents. In addition, Mr. Scelfo requested that Maxwell enter into an exclusivity agreement as it related to a proposed acquisition and delivered a draft to Dr. Fink. Dr. Fink then promptly informed the Maxwell board of directors of the letter of intent and interest from Tesla.

On December 16, 2018, Dr. Fink called Mr. Scelfo to inform him that the Maxwell board of directors would be holding a telephonic meeting on December 18, 2018, primarily for the purpose of approving a transaction unrelated to the Tesla non-binding letter of intent, and the Maxwell board of directors would also likely consider the Tesla offer at this meeting, but that based on Maxwell’s standalone plan and the moderate proposed premium to the Maxwell trading price represented by Tesla’s initial offer, the offer presented by Tesla would likely not be accepted by the Maxwell board of directors. Dr. Fink and Mr. Scelfo agreed that an in-person meeting between representatives of Tesla and Maxwell would be helpful for Tesla to further understand Maxwell’s products, technology and operations and the benefits of a potential acquisition transaction and allowing it to offer a higher valuation.

Between December 17 and December 19, 2018, Dr. Fink had numerous calls and email correspondence with Mr. Scelfo in order to prepare for an in-person meeting on December 20, 2018. Dr. Fink also informed Mr. Scelfo that the Maxwell board of directors declined Tesla’s offer, and that Tesla would need to increase its offer price to interest the Maxwell Board in a sale transaction.

On December 20, 2018, senior business development and engineering personnel and other members of Tesla management met with the CEO, CFO, senior operations personnel and other members of Maxwell management at Maxwell’s headquarters. Maxwell provided Tesla with further information regarding Maxwell’s products, technology and operations for the purpose of assisting Tesla with further analyzing the benefits of a potential acquisition transaction. Representatives of Tesla also provided information regarding Tesla’s programs and particular interest in Maxwell’s business, product lines and operations.

Following the meeting on December 20, 2018, Mr. Scelfo, on behalf of Tesla, delivered a revised non-binding letter of intent to Dr. Fink to acquire 100% of the outstanding shares of capital stock of Maxwell for a per share purchase price of $3.10, which represented a premium of 56% from the closing price of Maxwell’s stock on

31

December 20, 2018. Other terms of the offer remained the same as the initial letter of intent. Mr. Scelfo also indicated that a decision regarding a potential acquisition of Maxwell by Tesla would have to be reached quickly in order to not delay other important investment decisions at Tesla. Dr. Fink promptly provided the revised letter of intent to the Maxwell board of directors along with an update of his discussions with Mr. Scelfo.

After the December 22, 2018 Maxwell board of directors meeting, Dr. Fink informed Mr. Scelfo that Tesla’s revised offer was not accepted by the Maxwell board of directors and that the Maxwell board of directors would need a higher price in order to support a sale transaction with Tesla. Dr. Fink informed Mr. Scelfo, however, that he and his team were willing to work with Tesla through the holidays to help Tesla better understand the value that Tesla could realize through an acquisition of the company and further explain why the Maxwell board of directors was seeking a higher valuation.

Between December 23 and December 28, 2018, Dr. Fink had numerous email correspondences with Mr. Scelfo in order to conduct further diligence and discuss the benefits of a potential transaction. During this period, Mr. Scelfo also conveyed that Tesla was no longer interested in a potential strategic commercial arrangement with Maxwell and it would move in a different direction should Maxwell and Tesla be unable to reach an agreement regarding a potential acquisition of the entire capital stock of Maxwell.

After the December 28, 2018 Maxwell board of directors meeting, Dr. Fink contacted Mr. Scelfo via e-mail to discuss why the Maxwell board of directors felt a higher valuation was justified. Dr. Fink also provided Mr. Scelfo with a high-level summary of management’s net present value analysis, as reviewed by the Maxwell board of directors at the meeting earlier in the day. Dr. Fink also provided Mr. Scelfo with buy-in analysis of Maxwell’s larger institutional investors as previously previewed by the Maxwell board of directors. In addition, Dr. Fink reiterated that it was the view of the Maxwell board of directors that a higher value would likely be needed to gain the support of Maxwell’s largest institutional investors. At such time, Dr. Fink indicated to Mr. Scelfo that it was the Maxwell board of directors’ view that it would likely require at least $5.75—$6.00 per share to gain the support of Maxwell’s largest institutional investors.

Between January 3 and January 7, 2019, Dr. Fink had additional email and telephone correspondence with Mr. Scelfo.

On January 7, 2019, Mr. Scelfo, on behalf of Tesla, delivered a revised non-binding letter of intent to Dr. Fink to acquire 100% of the outstanding shares of capital stock of Maxwell for a per share purchase price of $4.35, which represented a premium of 75% from the closing price of Maxwell’s stock on January 7, 2019. The other terms of the offer remained the same as Tesla’s initial letter of intent. Dr. Fink shared the revised non-binding letter of intent with Maxwell’s Strategic Transaction Committee on the morning of January 8, 2019.

In connection with the revised offer, Dr. Fink and Mr. Scelfo agreed to arrange an additional in-person meeting pursuant to which Tesla could meet additional members of the Maxwell team and learn more about Maxwell’s operations, technology and products.

Dr. Fink and Mr. Scelfo continued to communicate via email in between January 7, 2019 and January 10, 2019, and Dr. Fink indicated that Tesla’s latest offer was unlikely to be accepted by the Maxwell board of directors.

On January 11, 2019, senior business development and engineering personnel and other members of Tesla management met with the CEO, CFO, senior operations personnel and other members of Maxwell management and personnel at Maxwell’s headquarters in San Diego. During the meetings, Tesla indicated that members of its management team would be having a technical and business review on the following Monday and an update on negotiations with Maxwell would be provided to Tesla’s Chief Executive Officer and Audit Committee. Tesla made it clear that their latest offer was at the high end of the range in which approval from its Audit Committee had been given. Moreover, Mr. Scelfo indicated that, while Tesla may consider any counter-proposal from Maxwell, any higher proposal from Maxwell may cause Tesla to discontinue discussions and explore any and all

32

alternative solutions available to Tesla, including alternatives that were simultaneously being considered or in development at Tesla.

On January 18, 2019, Mr. Scelfo, on behalf of Tesla, delivered a revised non-binding letter of intent to Dr. Fink. The offer continued to be an acquisition of 100% of the outstanding shares of capital stock of Maxwell. In the non-binding letter of intent, Tesla indicated a new per share purchase price of $4.75. While this was still lower than Maxwell’s initial request of $5.75—$6.00 per share that was discussed with Mr. Scelfo in December, it represented a premium of 66% from the closing price of Maxwell’s stock on January 17, 2019. Tesla indicated it would be amenable to discussing a fixed value construct, subject to a potential mutually agreed to price collar should Tesla share price move outside a certain percentage between signing and closing.

On January 20, 2019, Maxwell received a priority due diligence list from Tesla.

On January 23, 2019, Maxwell provided certain employees of Tesla with access to a virtual data room that contained materials regarding Maxwell’s business that were responsive to Tesla’s priority due diligence request list. Throughout the negotiation period, Maxwell continued to provide materials and Tesla continued to conduct due diligence on Maxwell.

From January 19 through January 22, 2019, Tesla and Maxwell continued to exchange revised drafts of the non-binding letter of intent and exclusivity agreement.

On January 23, 2019, Maxwell and Tesla entered into the non-binding letter of intent and an exclusivity and non-solicitation agreement with Tesla providing for exclusive negotiations through February 21, 2019. Later on January 23, 2019, Wilson Sonsini Goodrich and Rosati, Tesla’s outside legal advisors (“WSGR”), sent a draft of a proposed definitive merger agreement to representatives of DLA Piper LLP (US), Maxwell’s outside legal advisor (“DLA”). Neither the non-binding letter of intent nor the exclusivity and non-solicitation agreement included any standstill-related obligations on the part of Tesla relating to the potential acquisition or control of Maxwell.

Between January 23, 2019 and February 1, 2019, representatives of Maxwell held a number of lengthy management meetings in person and by conference call with various representatives of Tesla, during which in-depth financial, technological, legal and other due diligence was conducted, including meetings at Tesla’s offices on January 24 and 25, 2019, between members of Maxwell’s management and other employees of Tesla.

On January 24, 2019, representatives of DLA provided a revised draft of the definitive merger agreement to representatives of WSGR. Significant areas of negotiation included the scope and terms of the interim operating covenants, the timing of the closing and the outside date for the transaction, the structure of the transaction, the calculation of the Tesla trading price and collar terms, the terms upon which Maxwell could consider an alternative acquisition proposal and the process for dealing with any such proposal, and triggers for the possible payment of a termination fee and/or possible expense reimbursement.

On January 26, 2019, WSGR sent an initial draft of a form tender and support agreement in line with Tesla’s request to have certain Maxwell executive officers and all directors and their affiliated funds sign such an agreement. On January 27, 2019, representatives of DLA provided a revised draft of the form of tender and support agreement to representatives of WSGR, which was finalized over the course of the next several days.

On January 26, 2019, Tesla delivered a more extensive due diligence request list to Maxwell that supplemented the initial high priority due diligence request list. Maxwell continued to provide materials to Tesla in response to the due diligence request lists.

Between January 25 and February 2, 2019, representatives of DLA and representatives of WSGR exchanged drafts of the merger agreement and ancillary transaction documents and held telephonic discussions to progress negotiations between the parties on transaction terms.

33

On January 31, 2019, members of Maxwell management, along with representatives of DLA, held a conference call with members of Tesla management regarding reverse legal and financial due diligence by Maxwell of Tesla and Tesla Common Stock.

After the close of market trading on February 1, 2019, representatives of Tesla visited Maxwell’s facility in Peoria, Arizona, to view the commercial production facility. Members of Maxwell’s senior management and engineering personnel were also present.

On February 3, 2019, the Tesla board of directors held a special meeting and approved the terms of the merger agreement and the transactions contemplated thereby.

Following the meeting, on February 3, 2019, Maxwell and Tesla signed the definitive merger agreement and, before the open of markets on February 4, 2019, Maxwell issued a press release announcing the transaction.

Maxwell’s Reasons for the Offer and the Merger; Recommendation of the Maxwell Board of Directors

In evaluating the merger agreement and the transactions contemplated by the merger agreement, including the offer and the merger, the Maxwell board of directors consulted with Maxwell’s management, as well as Barclays, its external financial advisor, and DLA, its external legal counsel. In the course of reaching its determination that the offer and the merger are fair to, and in the best interests of Maxwell stockholders, and its recommendation that Maxwell stockholders accept the offer and tender their shares of Maxwell common stock in the offer, the Maxwell board of directors considered numerous reasons, including the following material reasons and benefits of the offer and merger, each of which the Maxwell board of directors believed supported its unanimous determination and recommendation:

34

35

In reaching its determinations and recommendations described above, the Maxwell board of directors also considered the following potentially negative reasons:

The foregoing discussion of the reasons considered by the Maxwell board of directors is intended to be a summary and is not intended to be exhaustive, but rather includes the material reasons considered by the

36

Maxwell board of directors. After considering these reasons, the Maxwell board of directors concluded that the positive reasons relating to the merger agreement and the transactions contemplated by the merger agreement, including the offer and the merger, substantially outweighed the potential negative reasons. The Maxwell board of directors collectively reached the unanimous conclusion to approve the merger agreement and the related transactions, including the offer and the merger, in light of the various reasons described above and other reasons that the members of the Maxwell board of directors believed were appropriate. In view of the wide variety of reasons considered by the Maxwell board of directors in connection with its evaluation of the merger agreement and the transactions contemplated by the merger agreement, including the offer and the merger, and the complexity of these matters, the Maxwell board of directors did not consider it practical, and did not attempt, to quantify, rank or otherwise assign relative weights to the specific reasons it considered in reaching its decision, and it did not undertake to make any specific determination as to whether any reasons, or any particular aspect of any reasons, supported or did not support its ultimate determination. Rather, the Maxwell board of directors made its recommendation based on the totality of information it received and the investigation it conducted. In considering the reasons discussed above, individual directors may have given different weights to different factors.

Tesla’s Reasons for the Offer and the Merger

In reaching its decision to approve the merger agreement, the offer, the merger and the other transactions contemplated by the merger agreement, Tesla’s board of directors consulted with Tesla’s management, as well as Tesla’s legal advisors, and considered a number of factors, including the following factors which it viewed as supporting its decision to approve the merger agreement, the offer, the merger and the other transactions contemplated by the merger agreement (not in any relative order of importance):

Tesla’s board of directors also considered a variety of uncertainties and risks and other potentially negative factors concerning the transactions, including the following (not in any relative order of importance):

37

Tesla’s board of directors concluded that the potential negative factors associated with the acquisition were outweighed by the potential benefits of completing the offer and the merger. Accordingly, Tesla’s board of directors approved the merger agreement, the offer, the merger and the other transactions contemplated by the merger agreement.

The foregoing discussion of the information and factors considered by the Tesla board of directors is not intended to be exhaustive, but includes the material positive and negative factors considered. The Tesla board of directors did not undertake to make any specific determination as to whether any factor, or any particular aspect of any factor, supported or did not support its ultimate determination. The Tesla board of directors based its determination on the totality of the information presented.

The financial projections prepared by Maxwell’s management referred to herein are set forth in “Item 4—The Solicitation or Recommendation” in the Schedule 14D-9.

Opinion of Maxwell’s Financial Advisor

Maxwell engaged Barclays Capital Inc. (“Barclays”) to act as its financial advisor with respect to pursuing strategic alternatives for Maxwell, including a possible sale of Maxwell, pursuant to an engagement letter dated January 24, 2017. On February 3, 2019, Barclays rendered its oral opinion (which was subsequently confirmed in writing) to Maxwell’s board of directors that, as of such date and based upon and subject to the qualifications, limitations and assumptions stated in its opinion, the consideration to be offered to the holders of Maxwell common stock (other than holders of cancelled shares and converted awards following the merger) pursuant to the merger agreement is fair, from a financial point of view, to such stockholders.

The full text of Barclays’ written opinion, dated as of February 3, 2019, is attached as Annex B. Barclays’ written opinion sets forth, among other things, the assumptions made, procedures followed, factors considered and qualifications and limitations upon the review undertaken by Barclays in rendering its opinion. You are encouraged to read the opinion carefully in its entirety. The following is a summary of Barclays’ opinion and the methodology that Barclays used to render its opinion. This summary is qualified in its entirety by reference to the full text of the opinion.

Barclays’ opinion, the issuance of which was approved by Barclays’ Valuation and Fairness Opinion Committee, is addressed to the board of directors of Maxwell, addresses only the fairness, from a financial point of view, of the consideration to be offered to the holders of Maxwell common stock (other than holders of converted awards

38

and cancelled shares following the merger) pursuant to the merger agreement and does not constitute a recommendation to any stockholder of Maxwell as to whether or not such stockholder should tender the shares of Maxwell common stock pursuant to the offer or how such stockholder should vote or act with respect to the proposed transaction or any other matter. The terms of the proposed transaction were determined through arm’s-length negotiations between Maxwell and Tesla and were unanimously approved by Maxwell’s board of directors. Barclays did not recommend any specific form of consideration to Maxwell or that any specific form of consideration constituted the only appropriate consideration for the proposed transaction. Barclays was not requested to address, and its opinion does not in any manner address, Maxwell’s underlying business decision to proceed with or effect the proposed transaction, the likelihood of the consummation of the proposed transaction, or the relative merits of the proposed transaction as compared to any other transaction in which Maxwell may engage. In addition, Barclays expressed no opinion on, and its opinion does not in any manner address, the fairness of the amount or the nature of any compensation to any officers, directors or employees of any parties to the proposed transaction, or any class of such persons, relative to the consideration to be offered to the stockholders of Maxwell in the proposed transaction. No limitations were imposed by Maxwell’s board of directors upon Barclays with respect to the investigations made or procedures followed by it in rendering its opinion.

In arriving at its opinion, Barclays, among other things:

In arriving at its opinion, Barclays assumed and relied upon the accuracy and completeness of the financial and other information used by Barclays without any independent verification of such information (and had not assumed responsibility or liability for any independent verification of such information). Barclays also relied upon the assurances of management of Maxwell that they were not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the financial projections of Maxwell, upon advice of Maxwell, Barclays assumed that such projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of Maxwell as to Maxwell’s future

39

financial performance and that Maxwell will perform substantially in accordance with such projections. In arriving at its opinion, Barclays assumed no responsibility for and expressed no view as to any such projections or estimates or the assumptions on which they were based. In arriving at its opinion, Barclays did not conduct a physical inspection of the properties and facilities of Maxwell and did not make or obtain any evaluations or appraisals of the assets or liabilities of Maxwell. Barclays’ opinion was necessarily based upon market, economic and other conditions as they existed on, and could be evaluated as of, February 3, 2019. Barclays assumed no responsibility for updating or revising its opinion based on events or circumstances that may have occurred after February 3, 2019. Barclays expressed no opinion as to the: (i) prices at which shares of Maxwell common stock would trade following the announcement or consummation of the proposed transaction or (ii) prices at which Tesla common stock would trade following the announcement or consummation of the proposed transaction, including whether the price of Tesla common stock will trade at a level at or below the floor price or any adjustment to the offer consideration resulting therefrom. Barclays’ opinion should not be viewed as providing any assurance that the market value of the shares of Tesla common stock to be held by the stockholders of Maxwell after the consummation of the proposed transaction will be in excess of the market value of Maxwell common stock owned by such stockholders at any time prior to the announcement or consummation of the proposed transaction.

Barclays assumed that the executed merger agreement would conform in all material respects to the last draft reviewed by Barclays. Additionally, Barclays assumed the accuracy of the representations and warranties contained in the merger agreement and all the agreements related thereto. Barclays also assumed, upon the advice of Maxwell, that all material governmental, regulatory and third party approvals, consents and releases for the proposed transaction would be obtained within the constraints contemplated by the merger agreement and that the proposed transaction will be consummated in accordance with the terms of the agreement without waiver, modification or amendment of any material term, condition or agreement thereof. Barclays did not express any opinion as to any tax or other consequences that might result from the proposed transaction, nor did Barclays’ opinion address any legal, tax, regulatory or accounting matters, as to which Barclays understood Maxwell had obtained such advice as it deemed necessary from qualified professionals.

In connection with rendering its opinion, Barclays performed certain financial, comparative and other analyses as summarized below. In arriving at its opinion, Barclays did not ascribe a specific range of values to the shares of Maxwell common stock but rather made its determination as to fairness, from a financial point of view, to the holders of Maxwell common stock (other than holders of cancelled shares and converted awards following the merger) of the consideration to be offered to such stockholders pursuant to the merger agreement on the basis of various financial and comparative analyses. The preparation of a fairness opinion is a complex process and involves various determinations as to the most appropriate and relevant methods of financial and comparative analyses and the application of those methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to summary description.

In arriving at its opinion, Barclays did not attribute any particular weight to any single analysis or factor considered by it but rather made qualitative judgments as to the significance and relevance of each analysis and factor relative to all other analyses and factors performed and considered by it and in the context of the circumstances of the particular transaction. Accordingly, Barclays believes that its analyses must be considered as a whole, as considering any portion of such analyses and factors, without considering all analyses and factors as a whole, could create a misleading or incomplete view of the process underlying its opinion.

Summary of Material Financial Analyses

The following is a summary of the material financial analyses used by Barclays in preparing its opinion to Maxwell’s board of directors. The summary of Barclays’ analyses and reviews provided below is not a complete description of the analyses and reviews underlying Barclays’ opinion. The preparation of a fairness opinion is a complex process involving various determinations as to the most appropriate and relevant methods of analysis and review and the application of those methods to particular circumstances, and, therefore, is not readily susceptible to summary description.

40

For the purposes of its analyses and reviews, Barclays made numerous assumptions with respect to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Maxwell or any other parties to the proposed transaction. No company, business or transaction considered in Barclays’ analyses and reviews is identical to Maxwell, Tesla, the Offeror or the proposed transaction, and an evaluation of the results of those analyses and reviews is not entirely mathematical. Rather, the analyses and reviews involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the acquisition, public trading or other values of the companies, businesses or transactions considered in Barclays’ analyses and reviews. None of Maxwell, Tesla, the Offeror, Barclays or any other person assumes responsibility if future results are materially different from those discussed. Any estimates contained in these analyses and reviews and the ranges of valuations resulting from any particular analysis or review are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than as set forth below. In addition, analyses relating to the value of companies, businesses or securities do not purport to be appraisals or reflect the prices at which the companies, businesses or securities may actually be sold. Accordingly, the estimates used in, and the results derived from, Barclays’ analyses and reviews are inherently subject to substantial uncertainty.

In connection with its analysis described below, per the instructions of Maxwell management, Barclays assumed (i) Maxwell total indebtedness of approximately $46 million, (ii) Maxwell total cash and investments of approximately $58 million, (iii) Maxwell shares of common stock of 46,008,549 outstanding on a fully diluted basis using the treasury stock method, (iv) Maxwell options of 356,117 outstanding with exercise prices ranging from $4.72 per share to $17.71 per share and (v) Maxwell restricted share units of 3,887,884.

The summary of the financial analyses and reviews summarized below include information presented in tabular format. In order to fully understand the financial analyses and reviews used by Barclays, the tables must be read together with the text of each summary, as the tables alone do not constitute a complete description of the financial analyses and reviews. Considering the data in the tables below without considering the full description of the analyses and reviews, including the methodologies and assumptions underlying the analyses and reviews, could create a misleading or incomplete view of Barclays’ analyses and reviews.

Selected Comparable Company Analysis

In order to assess how the public market values shares of similar publicly traded companies and to provide a range of relative implied equity values per share of Maxwell by reference to those companies, which could then be used to calculate implied equity value per share ranges, Barclays reviewed and compared specific financial and operating data relating to Maxwell with selected companies that Barclays, based on its experience in the energy storage and related industries, deemed comparable to Maxwell. The selected comparable companies were:

Barclays calculated and compared various financial multiples and ratios of Maxwell and the selected comparable companies. As part of its selected comparable company analysis, Barclays calculated and analyzed each company’s ratio of its enterprise value to its 2018, 2019 and 2020 estimated revenue. Revenue estimates were not

41

available for Highpower International, Inc. or Ultralife Corporation. The enterprise value (“EV”) of each company was calculated as (i) the sum of (a) the market value of its fully diluted equity value, using the treasury stock method, based on closing stock prices on February 1, 2019, (b) the amount of its short- and long-term debt, (c) the value of any preferred stock (at liquidation value), (d) the value of any pension liabilities and (e) the book value of any minority interest, less (ii) the value of its cash, cash equivalents and short and long-term liquid investments. All of these calculations for the comparable companies were performed, and, in the case of Maxwell were based on the financial and operating information and financial projections provided to Barclays by Maxwell management, and in the case of the selected comparable companies were based on publicly available financial data and closing prices, as of February 1, 2019, the last trading date prior to the delivery of Barclays’ opinion. The results of this selected comparable company analysis are summarized below:

Barclays selected the comparable companies listed above because of similarities in one or more business or operating characteristics with Maxwell. However, because of the inherent differences between the business, operations and prospects of Maxwell and those of the selected comparable companies, Barclays believed that it was inappropriate to, and therefore did not, rely solely on the quantitative results of the selected comparable company analysis. Accordingly, Barclays also made qualitative judgments concerning differences between the business, financial and operating characteristics and prospects of Maxwell and the selected comparable companies that could affect its public trading values in order to provide a context in which to consider the results of the quantitative analysis. These qualitative judgments related primarily to the differing sizes, growth prospects, profitability levels and degree of operational risk between Maxwell and the companies included in the selected company analysis. Based upon these judgments, Barclays selected a range of 1.25x to 1.75x to 2018 estimated EV / Revenue, 1.00x to 1.50x to 2019 estimated EV / Revenue, 1.00x to 1.50x to 2020 estimated EV / Revenue for Maxwell and applied such ranges to the management projections to calculate a range of implied equity values per share of Maxwell. The following summarizes the result of these calculations:

Barclays noted that on the basis of the selected comparable company analysis, the offer consideration of $4.75 per share, payable in Tesla common stock, based on the closing prices of Tesla and Maxwell common stock on February 1, 2019, was above the range of implied equity values per share calculated pursuant to the foregoing analysis.

42

Selected Precedent Transaction Analysis

Barclays reviewed and compared the purchase prices paid and implied financial multiples in selected other transactions that Barclays, based on its experience with merger and acquisition transactions in the energy storage and battery industry, deemed relevant. Barclays chose such transactions based on, among other things, the similarity of the applicable target companies in the transactions to Maxwell with respect to the size, mix, margins and other characteristics of their businesses. Using publicly available information, Barclays calculated and analyzed multiples of the EV to Revenue for the last twelve-months (“LTM Revenue”) implied by the prices paid in the selected precedent transactions.

The following table sets forth the transactions analyzed based on such characteristics and the results of such analysis ($ in millions):

Selected Precedent Transactions

The reasons for and the circumstances surrounding each of the selected precedent transactions analyzed were diverse and there are inherent differences in the business, operations, financial conditions and prospects of Maxwell and the companies included in the selected precedent transaction analysis. Accordingly, Barclays believed that a purely quantitative selected precedent transaction analysis would not be particularly meaningful in the context of considering the proposed transaction. Barclays therefore made qualitative judgments concerning differences between the characteristics of the selected precedent transactions and the proposed transaction which would affect the acquisition values of the selected target companies and Maxwell.

Based upon these judgments, Barclays selected a range of 1.25x to 2.00x to EV / LTM Revenue and applied such range to the LTM Revenue (for the 12-months period ending on December 31, 2018), per Maxwell management’s financial projections for Maxwell, to calculate a range of implied prices per share of Maxwell. Barclays’ selected precedent transactions analysis yielded a reference equity value range for Maxwell common stock of $2.51 to $3.87 per share.

Barclays noted that on the basis of the selected precedent transaction analysis, the offer consideration of $4.75 per share, payable in Tesla common stock, based on the closing prices of Tesla and Maxwell common

43

stock on February 1, 2019, was above the range of implied equity values per share calculated pursuant to the foregoing analysis.

Discounted Cash Flow Analysis

In order to estimate the present value of Maxwell common stock, Barclays performed a discounted cash flow analysis of Maxwell. A discounted cash flow analysis is a traditional valuation methodology used to derive a valuation of an asset by calculating the “present value” of estimated future cash flows of the asset. “Present value” refers to the current value of future cash flows or amounts and is obtained by discounting those future cash flows or amounts by a discount rate that takes into account macroeconomic assumptions and estimates of risk, the opportunity cost of capital, expected returns and other appropriate factors.

To calculate the estimated EV of Maxwell using the discounted cash flow method, Barclays assessed (i) Maxwell’s projected after-tax unlevered free cash flows for calendar years 2019 through 2025 based on management projections (see the section entitled “Item 4—The Solicitation or Recommendation” in the Schedule 14D-9) and (ii) the “terminal value” of Maxwell as of December 31, 2025, their present values assuming a mid-year convention for free cash flows for 2019—2025 and applying 6% tax rate (per Maxwell’s management) to the 2025 cash flow for the “terminal value” calculation purpose and using a range of selected discount rates and added such discounted amounts together. The after-tax unlevered free cash flows were calculated by taking the tax-effected EBIT (see the discussion in the section entitled “Item 4—The Solicitation or Recommendation” in the Schedule 14D-9), adding depreciation and subtracting capital expenditures and adjusting for changes in net working capital. The residual value of Maxwell at the end of the forecast period, or “terminal value,” was estimated by selecting a range of perpetuity growth rates of 3% to 5%, which was derived by Barclays utilizing its professional judgment and experience, taking into account Maxwell’s financial forecasts and market expectations and applying such range to Maxwell’s projections for the calendar year ending December 31, 2025.

Barclays analyzed the weighted average cost of capital for Maxwell, utilizing a risk-free rate of return based on the twenty year government bond yield as of February 1, 2019, a 5-year unadjusted beta for each of Maxwell and such selected comparable companies (outlined in the “Selected Comparable Companies Analysis”) per Bloomberg, normalized statutory tax rates, size premium for Maxwell based on the companies with $88 million - $166 million in equity value per Duff and Phelps, and historical long term equity risk premium per Duff and Phelps. This analysis indicated an approximately 18.41% weighted average cost of capital for Maxwell based on its current capital structure, a weighted average cost of capital for Maxwell of approximately 18.38% assuming Maxwell’s capital structure was comparable to the median of the comparable companies described above and a weighted average cost of capital of 15.33% for Maxwell based on the median of the unlevered beta and the median of the capital structure for such selected comparable companies. Based on the foregoing analysis, Barclays selected a range of discount rates of 14.0% to 18.0% was selected based on an analysis of the weighted average cost of capital of Maxwell and the selected comparable companies used in the “Selected Comparable Companies Analysis” described above. Barclays then calculated a range of implied prices per share of Maxwell by subtracting estimated net debt (including assumed make-whole payments under Maxwell’s convertible debt) as of December 31, 2018 from Maxwell’s estimated EV calculated using the discounted cash flow method and dividing such amount by the fully diluted number of shares of Maxwell, calculated using the treasury stock method, and using the number of Maxwell shares, options to purchase Maxwell shares and Maxwell restricted units outstanding as of January 31, 2019, per Maxwell management. The range of implied equity values per share of Maxwell common stock resulting from Barclays’ discounted cash flow analysis was $2.78—$5.74.

Barclays noted that on the basis of the discounted cash flow analysis, the offer consideration of $4.75 per share, payable in Tesla common stock, based on the closing prices of Tesla and Maxwell common stock on February 1, 2019, was within the range of implied equity values per share calculated pursuant to the foregoing analysis.

Other Factors

Barclays also reviewed and considered other factors, which were not considered part of its financial analyses in connection with rendering its advice, but were reviewed and provided for the Maxwell board of directors for informational purposes, including, among other things, the Historical Share Price Analysis and Transaction Premium Analysis described below.

Historical Share Price Analysis

In order to provide background information and perspective to the Maxwell board of directors with respect to, and to illustrate the trend in the historical trading prices of Maxwell common stock, Barclays considered historical data with regard to the trading prices of Maxwell common stock for the period from February 1, 2018 to February 1, 2019. Barclays noted that during the 52-week period preceding the date of Barclays’ fairness opinion, the closing price of Maxwell common stock ranged from $1.80 to $6.14.

Transaction Premium Analysis

In order to provide background information and perspective to the Maxwell board of directors with respect to, and to assess the implied premium offered to the holders of Maxwell common stock in the proposed transaction relative to the premiums offered to stockholders in other transactions, Barclays reviewed the 1-day and 30-day premiums paid in 280 global public technology M&A transactions greater than $25 million in value from February 1, 2016 to February 1, 2019 using publicly available information. The results of this transaction premium analysis are summarized below:

General

Barclays is an internationally recognized investment banking firm and, as part of its investment banking activities, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, investments for passive and control purposes, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. Maxwell’s board of directors selected Barclays because of its qualifications, reputation and experience in the valuation of businesses and securities in connection with mergers and acquisitions generally, as well as substantial experience in transactions comparable to the proposed transaction.

Barclays is acting as financial advisor to Maxwell in connection with the proposed transaction. As compensation for its services in connection with the proposed transaction, Maxwell has paid Barclays an opinion fee of $500,000 and has agreed to pay Barclays an additional transaction fee, currently estimated at approximately $4.37 million, which will be payable by Maxwell upon consummation of the transactions contemplated by the merger agreement. In addition, Maxwell has agreed to reimburse Barclays for its reasonable out-of-pocket expenses incurred in connection with the proposed transaction and to indemnify Barclays for certain liabilities that may arise out of its engagement by Maxwell and the rendering of Barclays’ opinion. Barclays has performed various investment banking and financial services for Maxwell, Tesla and their affiliates in the past, and expect to perform such services in the future, and have received, and expect to receive, customary fees for such services. During the past two years, Barclays has received fees for investment banking and financial services unrelated to the transaction contemplated by the merger agreement of approximately $4.9 million from Maxwell. In the past two years, Barclays has performed the following investment banking and financial services: (i) acted as bookrunner in connection with Tesla’s offering of $1.0 billion convertible notes in March 2017; (ii) acted as an

45

underwriter in connection with Tesla’s $402.5 million follow-on offering in March 2017; (iii) acted as financial advisor in connection with Maxwell’s Defense Advisory Settlement entered into in April 2017; (iv) acted as joint bookrunner in connection with Tesla’s inaugural high yield offering of $1.80 billion senior notes due 2025 in August 2017; (v) acted as an underwriter in connection with the Maxwell’s $46.0 million senior unsecured convertible notes offering in October 2017; (vi) acted as an underwriter in connection with the Maxwell’s $23.0 million follow-on offering in August 2018; and (vii) acted as financial advisor in connection with the Maxwell’s divestiture of its high voltage capacitors business in December 2018. In addition, (i) Barclays is currently engaged by the Maxwell to advise on certain corporate defensive advisory matters should they arise and we would receive customary fees in connection therewith; (ii) an affiliate of Barclays acts as a lender under Tesla’s $1.2 billion revolving credit facility which expires in June 2020; (iii) in addition to the lending relationship with Tesla specified in the preceding clause, an affiliate of Barclays also acts as a lender in connection with two other facilities with different entities affiliated with Tesla, both of which expire in August 2019; and (iv) Barclays remains in contact with Tesla concerning the possible future provision of investment banking and financial services.

Barclays, its subsidiaries and its affiliates engage in a wide range of businesses from investment and commercial banking, lending, asset management and other financial and non-financial services. In the ordinary course of its business, Barclays and affiliates may actively trade and effect transactions in the equity, debt and/or other securities (and any derivatives thereof) and financial instruments (including loans and other obligations) of Maxwell and Tesla and their respective affiliates for its own account and for the accounts of its customers and, accordingly, may at any time hold long or short positions and investments in such securities and financial instruments.

Distribution of Offering Materials

This document, the related letter of transmittal and other relevant materials will be delivered to record holders of Maxwell shares and to brokers, dealers, commercial banks, trust companies and similar persons whose names, or the names of whose nominees, appear on Maxwell’s stockholder list or, if applicable, who are listed as participants in a clearing agency’s security position listing, so that they can in turn send these materials to beneficial owners of Maxwell shares.

Expiration of the Offer

The offer commenced on February 20, 2019 and is scheduled to expire at 11:59 p.m., Eastern time, at the end of May 15, 2019, unless extended or terminated in accordance with the merger agreement. “Expiration date” means 11:59 p.m., Eastern time, at the end of May 15, 2019 unless and until the Offeror has extended the period during which the offer is open, subject to the terms and conditions of the merger agreement, in which event the term “expiration date” means the latest time and date at which the offer, as so extended by the Offeror, will expire.

Extension, Termination and Amendment of Offer

Subject to the provisions of the merger agreement and the applicable rules and regulations of the SEC, and unless Maxwell consents otherwise (which may be granted or withheld in its sole discretion) or the merger agreement is otherwise terminated:

46

No extension will impair, limit or otherwise restrict the right of the parties to terminate the merger agreement pursuant to its terms.

The Offeror may not terminate or withdraw the offer prior to the then-scheduled expiration of the offer unless the merger agreement is validly terminated in accordance with its terms, in which case the Offeror will terminate the offer promptly (but in no event more than one business day) after such termination. Among other circumstances, the merger agreement may be terminated by either Tesla or Maxwell if the offer shall have terminated or expired in accordance with its terms (subject to the rights and obligations of Tesla or the Offeror to extend the offer pursuant to the merger agreement) without the Offeror having accepted for payment any Maxwell shares pursuant to the offer, or if the acceptance for exchange of Maxwell shares tendered in the offer has not occurred on or before July 3, 2019, which we refer to as the “outside date.” See the section entitled “Merger Agreement—Termination of the Merger Agreement.”

The Offeror expressly reserves the right to waive any offer condition or modify the terms of the offer, except that the Offeror may not make certain changes to the offer or waive certain conditions to the offer without the prior written consent of Maxwell (which may be granted or withheld in its sole discretion). Changes to the offer that require the prior written consent of Maxwell include changes (i) that change the form of consideration to be paid in the offer, (ii) that decrease the consideration in the offer or the number of Maxwell shares sought in the offer, (iii) that extend the offer (other than in a manner required or permitted by the merger agreement), (iv) that impose conditions to the offer not included in the merger agreement, (v) that amend or modify any of the conditions to the offer or (vi) that amend or modify any other term of or condition to the offer in any manner that is adverse to the holders of Maxwell shares.

Conditions to the offer that the Offeror and Tesla may not amend, modify or waive without the prior written consent of Maxwell (which may be granted or withheld in its sole discretion) include (i) the minimum tender condition, (ii) the receipt of required regulatory approvals, (iii) lack of legal prohibitions, (iv) the effectiveness of the registration statement on Form S-4 of which this document is a part and (v) the approval for listing on the Nasdaq Global Select Market of the Tesla shares to be issued in the offer and the merger.

The Offeror will effect any extension, termination, amendment or delay of the offer by giving oral or written notice to the exchange agent and by making a public announcement as promptly as practicable thereafter. In the case of an extension, any such announcement will be issued no later than 9:00 a.m., Eastern time, on the next business day following the previously scheduled expiration date. Subject to applicable law (including Rules 14d-4(c) and 14d-6(d) under the Exchange Act, which require that any material change in the information published, sent or given to stockholders in connection with the offer be promptly disseminated to stockholders in a manner reasonably

47

designed to inform them of such change) and without limiting the manner in which the Offeror may choose to make any public announcement, the Offeror assumes no obligation to publish, advertise or otherwise communicate any such public announcement of this type other than by issuing a press release.

If the Offeror materially changes the terms of the offer or the information concerning the offer, or if the Offeror waives a material condition of the offer, in each case, subject to the terms and conditions of the merger agreement, the Offeror will extend the offer to the extent legally required under the Exchange Act.

For purposes of the offer, a “business day” means any day other than a Saturday, Sunday and any day which is a legal holiday under the laws of California or New York or is a day on which banking institutions located in such states are authorized or required by applicable law or other governmental action to close.

No subsequent offering period will be available following the expiration of the offer without the prior written consent of Maxwell, other than in accordance with the extension provisions set forth in the merger agreement.

Exchange of Shares; Delivery of Tesla Shares

Tesla has retained Computershare Trust Company, N.A. as the depositary and exchange agent for the offer and the merger (the “exchange agent”) to handle the exchange of Maxwell shares for the offer consideration in the offer and the merger.

Upon the terms and subject to the satisfaction or waiver of the conditions of the offer (including, if the offer is extended or amended in accordance with the merger agreement, the terms and conditions of any such extension or amendment), the Offeror will accept for exchange, and will exchange, Maxwell shares validly tendered and not validly withdrawn in the offer, promptly after the expiration of the offer. In all cases, a Maxwell stockholder will receive consideration for Maxwell shares tendered in the offer only after timely receipt by the exchange agent of certificates for those shares (or of a confirmation of a book-entry transfer of such shares into the exchange agent’s account at The Depository Trust Company (“DTC”)) (as described in “—Procedure for Tendering”) and a properly completed and duly executed letter of transmittal (or an agent’s message in connection with a book-entry transfer), together with any other required documents.

For purposes of the offer, the Offeror will be deemed to have accepted for exchange Maxwell shares validly tendered and not validly withdrawn if and when it notifies the exchange agent of its acceptance of those Maxwell shares pursuant to the offer. The exchange agent will deliver to the applicable Maxwell stockholders any Tesla shares issuable in exchange for Maxwell shares validly tendered and accepted pursuant to the offer promptly after receipt of such notice. The exchange agent will act as the agent for tendering Maxwell stockholders for the purpose of receiving Tesla shares from the Offeror and transmitting such Tesla shares to the tendering Maxwell stockholders.

If the Offeror does not accept any tendered Maxwell shares for exchange pursuant to the terms and conditions of the offer for any reason, or if certificates are submitted representing more shares than are tendered for, the Offeror will cause to be returned certificates for such unexchanged shares without expense to the tendering stockholder or, in the case of shares tendered by book-entry transfer into the exchange agent’s account at DTC pursuant to the procedures set forth below in “—Procedure for Tendering,” the Maxwell shares to be returned will be credited to an account maintained with DTC or otherwise credited to the tendering stockholder as soon as practicable following expiration or termination of the offer.

Withdrawal Rights

Maxwell stockholders can withdraw tendered Maxwell shares at any time until the expiration of the offer and, if the Offeror has not agreed to accept the shares for exchange on or prior to May 15, 2019, Maxwell stockholders can thereafter withdraw their shares from tender at any time after such date until the Offeror accepts shares for exchange. Any Maxwell stockholder that validly withdraws previously validly tendered Maxwell shares will receive shares of the same class of Maxwell common stock that were tendered.

48

For the withdrawal of Maxwell shares to be effective, the exchange agent must receive a written notice of withdrawal from the Maxwell stockholder at one of the addresses set forth elsewhere in this document prior to the expiration of the offer. The notice must include the Maxwell stockholder’s name, address, social security number (or tax identification number in the case of entities), the certificate number(s), if any, the number of shares to be withdrawn and the name of the registered holder, if it is different from that of the person who tendered those shares, and any other information required pursuant to the offer or the procedures of DTC, if applicable.

A financial institution must guarantee all signatures on the notice of withdrawal, unless the shares to be withdrawn were tendered for the account of an eligible institution. Most banks, savings and loan associations and brokerage houses are able to provide signature guarantees. An “eligible institution” is a financial institution that is a participant in the Securities Transfer Agents Medallion Program.

If shares have been tendered pursuant to the procedures for book-entry transfer discussed under the section entitled “—Procedure for Tendering,” any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn shares and must otherwise comply with DTC’s procedures. If certificates have been delivered or otherwise identified to the exchange agent, the name of the registered holder and the serial numbers of the particular certificates evidencing the shares withdrawn must also be furnished to the exchange agent, as stated above, prior to the physical release of such certificates.

The Offeror will decide all questions as to the form and validity (including time of receipt) of any notice of withdrawal in its sole discretion, and its decision will be final and binding, subject to any judgment of any court of competent jurisdiction. None of the Offeror, Tesla, Maxwell, the exchange agent, the information agent or any other person is under any duty to give notification of any defects or irregularities in any tender or notice of withdrawal or will incur any liability for failure to give any such notification. Any shares validly withdrawn will be deemed not to have been validly tendered for purposes of the offer. However, a Maxwell stockholder may re-tender withdrawn shares by following the applicable procedures discussed under the section “—Procedure for Tendering” at any time prior to the expiration of the offer.

Procedure for Tendering

To validly tender Maxwell shares held of record, Maxwell stockholders must:

If Maxwell shares of common stock are held in “street name” (i.e., through a broker, dealer, commercial bank, trust company or other nominee), those shares of common stock may be tendered by the nominee holding such shares by book-entry transfer through DTC. To validly tender such shares held in street name, Maxwell stockholders should instruct such nominee to do so prior to the expiration of the offer.

The exchange agent has established an account with respect to the Maxwell shares at DTC in connection with the offer, and any financial institution that is a participant in DTC may make book-entry delivery of Maxwell shares by causing DTC to transfer such shares prior to the expiration date into the exchange agent’s account in

49

accordance with DTC’s procedure for such transfer. However, although delivery of Maxwell shares may be effected through book-entry transfer at DTC, the letter of transmittal with any required signature guarantees, or an agent’s message, along with any other required documents, must, in any case, be received by the exchange agent at its address set forth elsewhere in this document prior to the expiration date. The term “agent’s message” means a message transmitted by DTC to, and received by, the exchange agent and forming a part of a book-entry confirmation, which states that DTC has received an express acknowledgment from the DTC participant tendering the shares that are the subject of such book-entry confirmation, that such participant has received and agrees to be bound by the terms of the letter of transmittal and that the Offeror may enforce that agreement against such participant.

The Offeror is not providing for guaranteed delivery procedures and therefore Maxwell stockholders who hold their shares through a DTC participant must allow sufficient time for the necessary tender procedures to be completed during normal business hours of DTC prior to the expiration date. Tenders received by the exchange agent after the expiration date will be disregarded and of no effect.

Signatures on all letters of transmittal must be guaranteed by an eligible institution, except in cases in which shares are tendered either by a registered holder of Maxwell shares who has not completed the box entitled “Special Issuance Instructions” or the box entitled “Special Delivery Instructions” on the letter of transmittal or for the account of an eligible institution.

If the Maxwell certificates for shares are registered in the name of a person other than the person who signs the letter of transmittal, or if payment is to be made or delivered to, or a share certificate not accepted for exchange or not tendered (including any certificate for unexchanged shares) is to be issued in the name of, a person other than the registered holder(s), the certificates must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name or names of the registered owner or owners appear on the certificates, with the signature or signatures on the stock powers guaranteed by an eligible institution.

The method of delivery of Maxwell certificates and all other required documents, including delivery through DTC, is at the option and risk of the tendering Maxwell stockholder, and delivery will be deemed made only when actually received by the exchange agent. If delivery is by mail, the Offeror recommends registered mail with return receipt requested and properly insured. In all cases, Maxwell stockholders should allow sufficient time to ensure timely delivery.

To prevent U.S. federal backup withholding, each Maxwell stockholder that is a U.S. person (as defined in the Code), other than a stockholder exempt from backup withholding as described elsewhere in this document, must provide the exchange agent with its correct taxpayer identification number and certify that it is not subject to U.S. federal backup withholding by timely completing the IRS Form W-9 included in the letter of transmittal. Certain stockholders (including, among others, certain foreign persons) are not subject to these backup withholding requirements. In order for a Maxwell stockholder that is a foreign person to qualify as an exempt recipient for purposes of U.S. federal backup withholding, the stockholder must timely submit an IRS Form W-8BEN, IRS Form W-8BEN-E or other applicable IRS Form W-8, signed under penalty of perjury, attesting to such person’s exempt status.

The acceptance for payment by the Offeror of Maxwell shares pursuant to any of the procedures described above will constitute a binding agreement between the Offeror and the tendering Maxwell stockholder upon the terms and subject to the conditions of the offer (including, if the offer is extended or amended in accordance with the merger agreement, the terms and conditions of any such extension or amendment).

No Guaranteed Delivery

The Offeror is not providing for guaranteed delivery procedures, and therefore Maxwell stockholders must allow sufficient time for the necessary tender procedures to be completed prior to the expiration

50

date. If Maxwell stockholders hold shares through a DTC participant, such stockholders must allow sufficient time for the necessary tender procedures to be completed during normal business hours of DTC prior to the expiration date. Maxwell stockholders must tender their Maxwell shares in accordance with the procedures set forth in this document. In all cases, the Offeror will exchange Maxwell shares tendered and accepted for exchange pursuant to the offer only after timely receipt by the exchange agent of certificates for shares (or timely confirmation of a book-entry transfer of such shares into the exchange agent’s account at DTC (as described in “—Procedure for Tendering”), a properly completed and duly executed letter of transmittal (or an agent’s message in connection with a book-entry transfer), together with any other required documents.

Grant of Proxy

By executing a letter of transmittal, subject to and effective upon acceptance for exchange of Maxwell shares tendered thereby, a Maxwell stockholder will irrevocably appoint the Offeror’s designees as such Maxwell stockholder’s attorneys-in-fact and proxies, each with full power of substitution, to exercise to the full extent such stockholder’s rights with respect to its Maxwell shares tendered and accepted for exchange by the Offeror and with respect to any and all other shares and other securities issued or issuable in respect of those Maxwell shares. That appointment is effective, and voting rights will be effected, when and only to the extent that the Offeror accepts tendered Maxwell shares for exchange pursuant to the offer and deposits with the exchange agent the offer consideration for such Maxwell shares. Furthermore, the letter of transmittal will not constitute a binding agreement between the signatory thereto and the Offeror until the Offeror accepts tendered Maxwell shares for exchange pursuant to the offer and deposits with the exchange agent the offer consideration for such Maxwell shares.

All such proxies, when effective, will be considered coupled with an interest in the tendered Maxwell shares and therefore will not be revocable. Upon the effectiveness of such appointment, all prior powers of attorney and proxies that the Maxwell stockholder has given will be revoked, and such stockholder may not give any subsequent powers of attorney or proxies (and, if given, they will not be deemed effective). The Offeror’s designees will, with respect to the Maxwell shares for which the appointment is effective, be empowered, among other things, to exercise all of such stockholder’s voting and other rights as they, in their sole discretion, deem proper at any annual, special or adjourned meeting of Maxwell’s stockholders or otherwise.

The Offeror reserves the right to require that, in order for Maxwell shares to be deemed validly tendered, immediately upon the Offeror’s acceptance of such shares for exchange, the Offeror must be able to exercise full voting rights with respect to such shares. However, prior to acceptance for exchange by the Offeror in accordance with terms of the offer, the appointment will not be effective, and the Offeror will have no voting rights as a result of the tender of Maxwell shares.

Fees and Commissions

Tendering registered Maxwell stockholders who tender Maxwell shares directly to the exchange agent will not be obligated to pay any charges or expenses of the exchange agent or any brokerage commissions. Tendering Maxwell stockholders who hold Maxwell shares through a broker, dealer, commercial bank, trust company or other nominee should consult that institution as to whether or not such institution will charge the Maxwell stockholder any service fees in connection with tendering Maxwell shares pursuant to the offer.

Matters Concerning Validity and Eligibility

The Offeror will determine questions as to the validity, form, eligibility (including time of receipt) and acceptance for exchange of any tender of Maxwell shares, in its sole discretion, and its determination will be final and binding to the fullest extent permitted by law, subject to any judgment of any court of competent jurisdiction. The Offeror reserves the absolute right to reject any and all tenders of Maxwell shares that it determines is not in the proper form or the acceptance of or exchange for which may be unlawful. The Offeror

51

also reserves the absolute right to waive any defect or irregularity in the tender of any Maxwell shares. No tender of Maxwell shares will be deemed to have been validly made until all defects and irregularities in tenders of such shares have been cured or waived. None of the Offeror, Tesla, Maxwell or any of their affiliates or assigns, the exchange agent, the information agent or any other person will be under any duty to give notification of any defects or irregularities in the tender of any Maxwell shares or will incur any liability for failure to give any such notification. The Offeror’s interpretation of the terms and conditions of the offer (including the letter of transmittal and instructions thereto) will be final and binding to the fullest extent permitted by law, subject to any judgment of any court of competent jurisdiction.

Maxwell stockholders who have any questions about the procedure for tendering Maxwell shares in the offer should contact the information agent at the address and telephone number set forth elsewhere in this document.

Announcement of Results of the Offer

The exchange ratio will be fixed at the close of business on the second trading day prior to the expiration date of the offer. Tesla will announce the number of shares of Tesla common stock to be exchanged for each Maxwell share by issuing a press release no later than 9:00 a.m., Eastern time, on the trading day prior to the final expiration date. If the offer is extended, Tesla will recalculate this information based on the later expected final expiration date and announce the new exchange ratio in a similar manner. Maxwell stockholders can call Georgeson LLC, the information agent, at (888) 643-8150 for answers to questions regarding the calculation of the exchange ratio.

Tesla will announce the final results of the offer, including whether all of the conditions to the offer have been satisfied or waived and whether the Offeror will accept the tendered Maxwell shares for exchange, as promptly as practicable following the expiration date. The announcement will be made by a press release in accordance with applicable securities laws and stock exchange requirements.

Purpose of the Offer and the Merger

The purpose of the offer is for Tesla to acquire control of, and ultimately the entire equity interest in, Maxwell. The offer, as the first step in the acquisition of Maxwell, is intended to facilitate the acquisition of Maxwell. Accordingly, if the offer is completed and as a second step in such plan, pursuant to the terms and subject to the conditions of the merger agreement, Tesla intends to promptly consummate a merger of the Offeror with and into Maxwell, with Maxwell surviving the merger, subject to the terms and conditions of the merger agreement. The purpose of the merger is for Tesla to acquire all Maxwell shares that it did not acquire in the offer. In the merger, each outstanding Maxwell share that was not acquired by Tesla or the Offeror in the offer will be converted into the right to receive the offer consideration. Upon consummation of the merger, the Maxwell business will be held in a wholly-owned subsidiary of Tesla, and the former stockholders of Maxwell will no longer have any direct ownership interest in the surviving corporation.

No Stockholder Approval

If the offer is consummated, Tesla is not required to and will not seek the approval of Maxwell’s remaining public stockholders before effecting the merger. Section 251(h) of the DGCL provides that following consummation of a successful tender offer for a public corporation, and subject to certain statutory provisions, if the acquiring corporation owns at least the amount of shares of each class of stock of the target corporation that would otherwise be required to approve a merger involving the target corporation, and the other stockholders receive the same consideration for their stock in the merger as was payable in the tender offer, the acquiring corporation can effect a merger without the action of the other stockholders of the target corporation. Accordingly, if the offer is completed, it will mean that the minimum tender condition has been satisfied, and if the minimum tender condition has been satisfied, it will mean that the merger will be subject to Section 251(h) of

52

the DGCL. Accordingly, if the offer is completed, Tesla intends to effect the closing of the merger without a vote of the Maxwell stockholders in accordance with Section 251(h) of the DGCL.

Non-Applicability of Rules Regarding “Going Private” Transactions

The SEC has adopted Rule 13e-3 under the Exchange Act, which is applicable to certain “going private” transactions, and which may under certain circumstances be applicable to the merger or another business combination following the acceptance of shares pursuant to the offer in which the Offeror seeks to acquire the remaining shares not held by it. The Offeror believes that Rule 13e-3 will not be applicable to the merger because it is anticipated that the merger will be effected within one year following the consummation of the offer and, in the merger, stockholders will receive the same consideration as that paid in the offer.

Plans for Maxwell

In connection with the offer, Tesla has reviewed and will continue to review various possible business strategies that it might consider in the event that the Offeror acquires control of Maxwell, whether pursuant to the offer, the merger or otherwise. Following a review of additional information regarding Maxwell, these changes could include, among other things, changes in Maxwell’s business, operations, personnel, employee benefit plans, corporate structure, capitalization and management. See also the section entitled “The Offer—Tesla’s Reasons for the Offer and the Merger.”

Delisting and Termination of Registration

Following consummation of the transactions, shares of Maxwell common stock will no longer be eligible for inclusion on the Nasdaq Global Market and will be withdrawn from listing. Assuming that Maxwell qualifies for termination of registration under the Exchange Act after the transactions are consummated, Tesla also intends to seek to terminate the registration of shares of Maxwell common stock under the Exchange Act. See “—Effect of the Offer on the Market for Maxwell Shares; Nasdaq Listing; Registration Under the Exchange Act; Margin Regulations.”

Board of Directors and Management; Organizational Documents

Upon consummation of the merger, the directors of the Offeror immediately prior to the consummation of the merger will be the directors of Maxwell, as the surviving corporation in the merger, and the officers of Maxwell immediately prior to the consummation of the merger will be the officers of Maxwell, as the surviving corporation in the merger. Upon consummation of the merger, the certificate of incorporation and bylaws of the Offeror as in effect immediately prior to the effective time of the merger will be the certificate of incorporation and bylaws of Maxwell, as the surviving corporation in the merger. Upon closing and after completion of Tesla’s review of Maxwell and its corporate structure, management and personnel, Tesla will determine what changes, if any, are desirable.

Ownership of Tesla Shares after the Offer and the Merger

Tesla estimates that former Maxwell stockholders would own, in the aggregate, approximately 0.51% of the outstanding Tesla shares immediately following consummation of the offer and the merger, assuming that:

53

Each Tesla share has one vote.

Effect of the Offer on the Market for Maxwell Shares; Nasdaq Listing; Registration under the Exchange Act; Margin Regulations

Effect of the Offer on the Market for Maxwell Shares

The purchase of shares of Maxwell common stock by the Offeror pursuant to the offer will reduce the number of holders of shares of Maxwell common stock and the number of shares of Maxwell common stock that might otherwise trade publicly and could adversely affect the liquidity and market value of the remaining shares of Maxwell common stock held by the public. The extent of the public market for shares of Maxwell common stock after consummation of the offer and the availability of quotations for such shares will depend upon a number of factors, including the number of stockholders holding shares of Maxwell common stock, the aggregate market value of the shares of Maxwell common stock held by the public at such time, the interest of maintaining a market in the shares of Maxwell common stock, analyst coverage of Maxwell on the part of any securities firms and other factors. However, under the merger agreement, the closing of the merger must occur promptly, and in any case no later than the second business day, after the acceptance of tendered Maxwell shares in the offer and the satisfaction of the other condition to the merger, unless the parties agree otherwise in writing (see the section entitled “Merger Agreement—Conditions to the Merger”). If the merger is completed, shares of Maxwell common stock will no longer qualify for inclusion on the Nasdaq Global Market and will be withdrawn from listing.

Nasdaq Listing

Shares of Maxwell common stock are currently listed on the Nasdaq Global Market. However, the rules of Nasdaq establish certain criteria that, if not met, could lead to the discontinuance of listing of shares of Maxwell common stock from Nasdaq. Among such criteria are the number of stockholders, the number of shares publicly held and the aggregate market value of the shares publicly held. If, as a result of the purchase of shares of Maxwell common stock pursuant to the offer or otherwise, shares of Maxwell common stock no longer meet the requirements of Nasdaq for continued listing and the shares of Maxwell common stock are delisted, the market for such shares would be adversely affected.

Following the consummation of the offer, if the merger is for some reason not consummated, it is possible that shares of Maxwell common stock could be traded on other securities exchanges (with trades published by such exchanges), the OTC Bulletin Board or in a local or regional over-the-counter market. The extent of the public market for such shares would, however, depend upon the number of Maxwell stockholders and the aggregate market value of shares of Maxwell common stock remaining at such time, the interest in maintaining a market in such shares on the part of securities firms, the possible termination of registration of shares of Maxwell common stock under the Exchange Act and other factors. If the merger is completed, shares of Maxwell common stock will no longer qualify for inclusion on Nasdaq and will be withdrawn from listing.

Registration under the Exchange Act

Shares of Maxwell common stock are currently registered under the Exchange Act. Such registration may be terminated upon application by Maxwell to the SEC if shares of Maxwell common stock are neither listed on a national securities exchange nor held by 300 or more holders of record. Termination of registration of shares of Maxwell common stock under the Exchange Act would substantially reduce the information required to be

54

furnished by Maxwell to its stockholders and to the SEC and would make certain provisions of the Exchange Act no longer applicable to Maxwell, such as the short-swing profit recovery provisions of Section 16(b) of the Exchange Act, the requirement of furnishing a proxy statement pursuant to Section 14(a) of the Exchange Act in connection with meetings of stockholders and the related requirement of furnishing an annual report to stockholders, and the requirements of Rule 13e-3 under the Exchange Act with respect to “going private” transactions. Furthermore, the ability of “affiliates” of Maxwell and persons holding “restricted securities” of Maxwell to dispose of such securities pursuant to Rule 144 promulgated under the Securities Act may be impaired. If registration of shares of Maxwell common stock under the Exchange Act were terminated, such shares would no longer be “margin securities” or be eligible for quotation on Nasdaq. After consummation of the offer, Tesla and the Offeror currently intend to cause Maxwell to terminate the registration of shares of Maxwell common stock under the Exchange Act as soon as the requirements for termination of registration are met.

Conditions of the Offer

Notwithstanding any other provisions of the offer and in addition to Tesla’s and the Offeror’s rights to extend, amend or terminate the offer in accordance with the terms and conditions of the merger agreement and applicable law, and in addition to the obligations of the Offeror to extend the offer pursuant to the terms and conditions of the merger agreement and applicable law, the Offeror and Tesla are not required to accept for exchange or, subject to any applicable rules and regulations of the SEC (including Rule 14e-1(c) under the Exchange Act), exchange the offer consideration for any Maxwell shares validly tendered in the offer and not validly withdrawn prior to the expiration of the offer, if at the expiration of the offer any of the following conditions have not been satisfied or waived in accordance with the merger agreement:

55

Except as expressly set forth in the merger agreement, the foregoing conditions to the offer are for the sole benefit of Tesla and the Offeror and may be asserted by Tesla or the Offeror regardless of the circumstances giving rise to any such conditions or may be waived by Tesla or the Offeror, by express and specific action to that effect, in whole or in part at any time and from time to time, in each case, prior to the expiration of the offer. However, certain specified conditions may only be waived by Tesla or the Offeror with the prior written consent of Maxwell (which may be granted or withheld in its sole discretion). These conditions are the minimum tender condition, the receipt of required regulatory approvals, lack of legal prohibitions, the Tesla shares to be issued in the offer and the merger having been approved for listing on the Nasdaq Global Select Market, subject to official notice of issuance, and the registration statement on Form S-4, of which this document is a part, having become effective. There is no financing condition to the offer.

Certain Legal Proceedings; Regulatory Approvals

General

Tesla is not aware of any governmental license or regulatory permit that appears to be material to Maxwell’s business that might be adversely affected by the acquisition of Maxwell shares pursuant to the offer or the merger or, except as described below, of any approval or other action by any government or governmental administrative or regulatory authority or agency, domestic or foreign, that would be required for the acquisition or ownership of Maxwell shares pursuant to the offer or the merger. Should any of these approvals or other actions be required, Tesla and the Offeror currently contemplate that these approvals or other actions will be sought. There can be no assurance that (a) any of these approvals or other actions, if needed, will be obtained (with or without substantial

56

conditions), (b) if these approvals were not obtained or these other actions were not taken, adverse consequences would not result to Maxwell’s business or (c) certain parts of Maxwell’s or any of its subsidiaries’ businesses would not have to be disposed of or held separate. The Offeror’s obligation under the offer to accept for exchange and pay for shares is subject to certain conditions. See the section entitled “The Offer—Conditions of the Offer.”

Subject to the terms and conditions of the merger agreement, Tesla and Maxwell have agreed to use their reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable law to consummate the offer and the merger as soon as practicable after the date of the merger agreement. Notwithstanding the foregoing, none of Tesla, the Offeror or any of their respective subsidiaries is required to, and Maxwell may not and may not permit any of its subsidiaries to, without the prior written consent of Tesla, become subject to, consent to or offer or agree to, or otherwise take any action with respect to, any requirement, condition, limitation, understanding, agreement or order to (a) sell, license, assign, transfer, divest, hold separate or otherwise dispose of any assets, business or portion of business of Maxwell, Tesla or their respective subsidiaries, (b) conduct, restrict, operate, invest or otherwise change the assets, the business or portion of the business of Maxwell, Tesla or their respective subsidiaries or (c) impose any restriction, requirement or limitation on the operation of the business or portion of the business of Maxwell, Tesla or their respective subsidiaries. However, if requested by Tesla, Maxwell or its subsidiaries will become subject to, consent to or offer or agree to, or otherwise take any action with respect to, any such requirement, condition, limitation, understanding, agreement or order so long as such requirement, condition, limitation, understanding, agreement or order is only binding on Maxwell or its subsidiaries in the event the merger is completed.

HSR Act

Under the HSR Act and the rules that have been promulgated thereunder, the offer may not be completed until Tesla files a Notification and Report Form with the Federal Trade Commission (“FTC”) and the Antitrust Division of the U.S. Department of Justice (the “DOJ”) under the HSR Act, and the applicable waiting period has expired or been terminated, which is also a condition to the consummation of the Offer. The HSR Act also requires Maxwell to file a Notification and Report Form with the FTC and DOJ.

Pursuant to the requirements of the HSR Act, Tesla and Maxwell each filed a Notification and Report Form with respect to the offer and the merger with the Antitrust Division of the DOJ and the FTC on February 4, 2019. The 30-day waiting period under the HSR Act would have expired at 11:59 p.m., Eastern time, on March 6, 2019, unless terminated early or extended by a request for additional information and documentary materials. On February 14, 2019, the FTC notified Tesla and Maxwell that early termination of the 30-day waiting period had been granted.

At any time before or after consummation of the transactions, notwithstanding the termination or expiration of the waiting period under the HSR Act, the FTC or the DOJ could take such action under the antitrust laws as it deems necessary under the applicable statutes, including seeking to enjoin the completion of the offer or the merger, seeking divestiture of substantial assets of the parties, or requiring the parties to license, or hold separate, assets or terminate existing relationships and contractual rights. At any time before or after the completion of the transactions, and notwithstanding the termination or expiration of the waiting period under the HSR Act, any state could take such action under the antitrust laws as it deems necessary. Such action could include seeking to enjoin the completion of the offer or the merger or seeking divestiture of substantial assets of the parties, or requiring the parties to license, or hold separate, assets or terminate existing relationships and contractual rights. Private parties may also seek to take legal action under the antitrust laws under certain circumstances.

There can be no assurance that a challenge to the transactions on antitrust grounds will not be made, or if such a challenge is made, what the result will be. See the section entitled “The Offer—Conditions of the Offer” for certain conditions to the offer, including conditions with respect to the HSR Act.

57

German ARC

The German Act Against Restraints of Competition of 1958 (the “German ARC”) imposes a pre-merger notification requirement on all transactions that qualify as concentrations and meet certain specified financial thresholds, which the merger meets. Accordingly, consummation of the merger is conditional upon the merger being cleared by the Bundeskartellamt. Clearance can be granted explicitly or is also considered granted if, after a transaction has been notified, the applicable waiting periods expire without any decision by the Bundeskartellamt. Tesla notified the Bundeskartellamt of the proposed transaction to on February 7, 2019, and the Bundeskartellamt notified Tesla and Maxwell that clearance of the offer had been approved on March 7, 2019.

Certain Legal Proceedings

In connection with the merger agreement and the transactions contemplated thereby, nine purported class action lawsuits have been filed. Five complaints, captioned Kip Leggett v. Maxwell Technologies, Inc., et al., Case No. 3:19-cv-00377 (filed February 26, 2019), Shiva Stein v. Maxwell Technologies, Inc., et al., Case No. 3:19-cv-00395 (filed February 26, 2019), Joel Rosenfeld IRA v. Maxwell Technologies, Inc., et al., Case No. 3:19-cv-00413 (filed March 1, 2019), Franck Prissert v. Maxwell Technologies, Inc., et al., Case No. 3:19-cv-00429 (filed March 4, 2019) and Jonathan Mantak v. Maxwell Technologies, Inc., et. al., Case No. 3:19-cv-00451 (filed March 7, 2019) were filed in the United States District Court for the Southern District of California. Two complaints, captioned John Solak v. Maxwell Technologies, Inc., et al., Case No. 1:19-cv-00448 (filed March 4, 2019) and Sabatini v. Maxwell Technologies, Inc., et al., Case No. 1:19-cv-00443 (filed March 1, 2019), were filed in the United States District Court District of Delaware. One complaint, captioned Davis Rodden v. Steven Bilodeau, et al., Case No. 2019-0176 (filed March 4, 2019), was filed in the Delaware Chancery Court and was voluntarily dismissed on April 3, 2019. One complaint, captioned Jack Phillipps v. Maxwell Technologies, Inc., et al., Case No. 1:19-cv-01927 (filed February 28, 2019), was filed in the United States District Court for the Southern District of New York.

In general, the complaints assert claims against Maxwell and the Maxwell board of directors, with Tesla and the Offeror as additional defendants in the Kip Leggett v. Maxwell Technologies, Inc., et al., Sabatini v. Maxwell Technologies, Inc., et al., and John Solak v. Maxwell Technologies, Inc., et al. complaints. The complaints allege, among other things, that the defendants failed to make adequate disclosures in the Schedule 14D-9 filed by Maxwell on February 20, 2019. The complaints seek, among other things, to enjoin the proposed transaction, rescission of the proposed transaction should it be completed, and other equitable relief.

Tesla and Maxwell believe the respective allegations in these complaints lack merit, and Tesla and Maxwell intend to vigorously defend the actions.

Interests of Certain Persons in the Offer and the Merger

Maxwell’s directors and executive officers may have interests in the offer, the merger, and the other transactions contemplated by the merger agreement that are different from, or in addition to, the interests of the Maxwell stockholders generally. These interests may create potential conflicts of interest. The Maxwell board of directors was aware of these interests and considered them, among other matters, in approving the merger agreement and the transactions contemplated by the merger agreement, as more fully discussed in the section entitled “The Offer—Maxwell’s Reasons for the Offer and Merger; Recommendation of the Maxwell Board of Directors.”

58

Current Executive Officers and Directors

Maxwell’s current directors and executive officers are:

Arrangements with Tesla

As of the date of this document, none of Maxwell’s executive officers has entered into any agreement with Tesla or any of its subsidiaries or affiliates regarding employment with Tesla or any of its subsidiaries or affiliates. Prior to and following the closing of the merger, however, certain of our executive officers may have discussions, and following the closing of the merger, may enter into agreements with, Tesla or its subsidiaries or affiliates regarding employment with Tesla or its subsidiaries or affiliates.

Effect of the Offer and the Merger on Maxwell Common Stock and Equity Awards

Consideration for Maxwell Common Stock in the Merger

The following table sets forth the number of shares of Maxwell common stock beneficially owned as of February 11, 2019 by each of our executive officers and directors, excluding shares issuable upon exercise of stock options, Maxwell Time-based RSU Awards (as defined below) not vesting within 60 days of February 11, 2019, or Maxwell MSUs (as defined below) or Maxwell PSUs (as defined below) and the aggregate offer consideration payable for such shares. Each holder of shares of Maxwell common stock who otherwise would be entitled to receive a fraction of a share of Tesla common stock under the merger agreement will receive cash, without interest, in an amount equal to such fractional part of a share of Tesla common stock multiplied by the volume weighted average of the daily volume weighted average of the trading price of one (1) share of Tesla common stock as reported on the Nasdaq Global Select Market for the five (5) consecutive trading days immediately preceding the second trading day prior to the date of the expiration of the offer (the “Tesla trading price”), subject to the minimum. For the avoidance of doubt, if the offer were to expire at 11:59 p.m., Eastern time on a Tuesday, then the five (5) consecutive trading days would be the preceding Monday through Friday assuming each day prior to the Tuesday expiration date was a trading day (other than Saturday or Sunday). In the event that the Tesla trading price is equal to or less than $245.90, the minimum will apply and each share of Maxwell common stock validly tendered and not validly withdrawn will be exchanged for 0.0193 of a share of Tesla common stock. The amounts in this table assume the merger occurred on February 11, 2019, and that the offer consideration was 0.0152 shares of Tesla common stock for each share of Maxwell common stock which is calculated by dividing $4.75 by $312.84 (which is the closing price of Tesla common stock on February 11, 2019). This information is based on the number of shares of Maxwell common stock held by Maxwell’s directors and executive officers as of February 11, 2019 (and includes the deferred, fully vested restricted stock units pursuant to Maxwell’s non-employee director deferred compensation program, which will be settled immediately prior to the merger as described below, restricted stock units vesting within 60 days of February 11, 2019 and the shares payable pursuant to Maxwell’s 2018 annual

59

incentive bonus plan described in footnote 1 to the table below). The amounts set forth in the table below are as calculated before any taxes that may be due on such amounts are paid.

Consideration for Maxwell Options in the Merger—Generally

At the effective time of the merger, each option to purchase shares of Maxwell common stock that was granted under the 2005 Plan or the 2013 Plan (each such option or any Inducement Option (as defined below), a “Maxwell option”), that is outstanding, unexercised and unexpired as of immediately prior to the effective time (other than any Former Service Provider Options) shall be automatically assumed by Tesla and converted into and become an option to acquire Tesla common stock, on the same terms and conditions as were applicable to such Maxwell option as of immediately prior to the effective time (a “Converted Option”), except that: (x) the number of shares of Tesla common stock subject to the Converted Option will be determined by multiplying the number of shares of Maxwell common stock subject to the corresponding Maxwell option by the offer consideration and (y) the per share exercise price for each share of Tesla common stock that may be acquired upon exercise of the Maxwell option will be determined by dividing the per share exercise price of the Maxwell option by the offer consideration, with any fractional cent in the resulting quotient rounded up to the nearest whole cent. Each Converted Option otherwise shall be subject to the same terms and conditions applicable to the corresponding Maxwell option and the agreement evidencing the Maxwell option thereunder, including vesting terms.

60

Each Former Service Provider Option shall not be treated in the same manner. At the effective time, without any action on the part of Tesla, Maxwell or the holder of the Former Service Provider Option, each Former Service Provider Option shall be cancelled and converted into the right to receive a number of shares of Tesla common stock determined as: (i) (A) the number of shares of Maxwell common stock subject to the Former Service Provider Option immediately prior to the effective time, multiplied by (B) the offer consideration, minus (ii) (A) the aggregate exercise or purchase price for all shares of Maxwell common stock subject to such Former Service Provider Option divided by (B) the Tesla trading price, with any resulting fractional share rounded down to the nearest whole share.

In addition, the option to purchase shares of Maxwell common stock granted pursuant to the non-plan stock option agreement by and between Maxwell and David Lyle dated May 11, 2015 (the “Inducement Option”), will be treated in the same manner as a Maxwell option at the effective time, as described above.

Consideration for Maxwell Restricted Stock Units in the Merger—Generally

At the effective time, each Maxwell RSU award that was granted under the 2005 Plan or 2013 Plan, whether vesting thereof is based on service, performance, stock performance or other conditions, or any Inducement RSU (as defined below) that is outstanding immediately prior to the effective time (other than any Former Service Provider RSUs), shall be assumed by Tesla and converted automatically into and become a restricted stock unit covering shares of Tesla common stock, on the same terms and conditions as were applicable under the Maxwell RSU award as of immediately prior to the effective time, except that the number of shares of Tesla common stock subject to such converted Maxwell RSU award will be determined by multiplying the number of shares of Maxwell common stock subject to the corresponding Maxwell RSU award immediately prior to the effective time, by the offer consideration, with any fractional shares in the resulting product rounded down to the nearest whole share (the “Converted RSUs” and, together with the Converted Options, the “Converted Awards”). Each Converted RSU otherwise shall be subject to the same terms and conditions applicable to the corresponding Maxwell RSU award under the applicable Maxwell Equity Plan and any agreement evidencing the Maxwell RSU award thereunder, including vesting terms.

Each Former Service Provider RSU shall not be treated in the same manner. At the effective time, without any action on the part of Tesla, Maxwell or the holder of the Former Service Provider RSU, each Former Service Provider RSU shall be cancelled and converted into the right to receive a number of shares of Tesla common stock determined as: (i) (A) the number of shares of Maxwell common stock subject to the Former Service Provider RSU immediately prior to the effective time, multiplied by (B) the offer consideration, minus (ii) (A) the aggregate exercise or purchase price for all shares of Maxwell common stock subject to such Former Service Provider RSU divided by (B) the Tesla trading price, with any resulting fractional share rounded down to the nearest whole share.

In addition, the RSU awards granted pursuant to the non-plan restricted stock unit award by and between Maxwell and David Lyle dated May 11, 2015 (the “Inducement RSUs”) will be treated in the same manner as a Maxwell RSU award at the effective time, as described above.

Consideration for Maxwell Options and Maxwell RSU Awards Held by Directors and Executive Officers in the Merger

Treatment of Director Equity Awards

As of February 11, 2019, Maxwell’s non-employee directors held Maxwell options to purchase an aggregate of 60,000 shares of Maxwell common stock, with per share exercise prices ranging from $5.37 to $5.33. As of the same date, Maxwell’s non-employee directors held Maxwell RSU awards covering an aggregate of 234,241 shares. Of these awards, 115,531 were vested Maxwell RSU awards with deferred settlement (“Deferred RSUs”). The unvested Maxwell RSU awards held by non-employee directors vest based solely on continued service with Maxwell through the applicable vesting dates (“Maxwell Time-based RSU Awards”).

61

At the effective time, each Maxwell option and Maxwell Time-based RSU Award that is outstanding and held by a current or former non-employee director of Maxwell will vest and be cancelled and converted into the right to receive a number of shares of Tesla common stock determined as: (i) (A) the number of shares of Maxwell common stock subject to the Maxwell option immediately prior to the effective time, multiplied by (B) the offer consideration, minus (ii) (A) the aggregate exercise or purchase price for all shares of Maxwell common stock subject per share to such Maxwell option divided by (B) the Tesla trading price, with any resulting fractional share rounded down to the nearest whole share.

In early 2017, the Maxwell board of directors approved a non-employee director deferred compensation program pursuant to which participating non-employee directors may make irrevocable elections on an annual basis to take fully vested restricted stock units in lieu of their cash-based non-employee director fees (including, as applicable, any annual retainer fee, committee fee and any other compensation payable with respect to their service as a member of the Maxwell board of directors) and to defer the settlement upon the vesting of all or a portion of their equity awards granted in the applicable calendar year. In the event that a director makes such an election, Maxwell will grant fully vested restricted stock units in lieu of cash, with an initial value equal to the cash fees, which will be settled immediately after grant or at a future date elected by the respective non-employee director through the issuance of Maxwell common stock. This program was implemented with the intention of further aligning the interests of directors with those of Maxwell’s stockholders by enabling non-employee directors a vehicle to increase their equity stake by receiving payment in the form of equity instead of cash. The participation in this program is optional for non-employee directors. In 2017, the first year of the program, non-employee directors were able to make elections regarding their compensation for the second through the fourth quarter. With the program fully implemented prior to the end of the calendar year, all non-employee directors were able to make elections for 2018 and 2019 compensation for the entirety of the calendar year.

The non-employee director compensation program provides that, in the event of our change in control, each outstanding award of Deferred RSUs held by a non-employee director will be settled in shares of Maxwell common stock as of immediately prior to the effective time. Accordingly, shares of Maxwell common stock issued pursuant to Deferred RSUs will be treated in the same manner as other shares of Maxwell common stock outstanding immediately prior to the effective time, as described further above. Under the non-employee director deferred compensation program, “change in control” will include the merger and generally has the meaning set forth below with respect to the other Maxwell RSU awards described below.

Please see “—Table of Estimated Consideration for Equity Awards” below for additional information.

Treatment of Executive Officer Equity Awards

As of February 11, 2019, Maxwell’s executive officers held Maxwell options to purchase an aggregate of 150,599 shares of Maxwell common stock, with per share exercise prices ranging from $6.03 to $15.71. As of the same date, Maxwell’s executive officers held Maxwell RSU awards covering 990,969 shares of Maxwell common stock. Of these awards, an aggregate of 361,955 shares of Maxwell common stock are subject to Maxwell RSU awards that were granted with service-based vesting. Maxwell RSU awards that were granted with vesting contingent in part on achievement of performance goals based on relative total stockholder return (“Maxwell MSUs”) cover an aggregate of 558,044 shares of Maxwell common stock (based on target achievement of the applicable performance goals). Maxwell RSU awards that were granted with vesting contingent in part on achievement of performance goals relating other than to relative total stockholder return (“Maxwell PSUs”) cover an aggregate of 70,970 shares of Maxwell common stock (based on target achievement of the applicable performance goals).

Assuming continued employment through the effective time, all Maxwell options and Maxwell RSU awards that are outstanding as of immediately prior to the effective time held by Maxwell’s executive officers will be assumed and converted into awards covering shares of Tesla common stock, as discussed above.

62

Pursuant to the terms of the equity award agreements governing each of the Maxwell options and Maxwell RSU awards held by each of the executive officers, if, within thirty (30) days prior to or two years following the date of a change in control of Maxwell, which will include the merger, the executive officer’s employment is terminated by Maxwell without cause (as such term is defined in the applicable equity award agreement) or the executive officer resigns for good reason (as such term is defined in the applicable equity award agreement), then vesting with respect to 100% of the then unvested shares subject to the Maxwell option or Maxwell Time-based RSU Award will accelerate. With respect to Dr. Fink’s Maxwell PSUs granted on February 18, 2016, this grant will vest based on actual achievement of applicable performance conditions in connection with the signing of the merger agreement on February 3, 2019, which certification is expected to occur prior to the merger. With respect to Mr. Lyle’s Maxwell PSUs granted on February 18, 2016, this grant will be treated in the same manner as his outstanding Maxwell options and Maxwell RSU awards but is subject to earlier vesting based on actual achievement of applicable performance conditions as of December 31, 2018, which certification is expected to occur prior to the merger. With respect to the Maxwell MSUs, up to 100% of the Maxwell MSUs will vest based on target levels on the effective date of the change in control, provided that such acceleration will not result in the cumulative vesting of more than 100% of such Maxwell MSUs.

For purposes of the Maxwell Time-based RSU Awards, Maxwell PSUs and Maxwell MSUs, “cause” generally means a grantee’s unauthorized use or disclosure of the Maxwell’s confidential information or trade secrets; breach of any agreement between the grantee and Maxwell; grantee’s material failure to comply with Maxwell’s written policies or rules; grantee’s conviction of, or your plea of “guilty” or “no contest” to, a felony; grantee’s gross negligence or willful misconduct; grantee’s continuing failure to perform assigned duties after receiving written notification from Maxwell; or grantee’s failure to cooperate in good faith with a governmental or internal investigation.

For purposes of the Maxwell Time-based RSU Awards, Maxwell PSUs and Maxwell MSUs, “change in control” will include the merger and generally means any person acquiring beneficial ownership of more than 50% of Maxwell’s total voting power; the sale or disposition of all or substantially all of Maxwell’s assets; or any merger or consolidation of Maxwell where Maxwell’s voting securities represent 50% or less of the total voting power of the surviving entity or its parent.

For purposes of the Maxwell Time-based RSU Awards, Maxwell PSUs, and Maxwell MSUs “good reason” generally means a change in grantee’s position that materially reduces his or her level of authority or responsibility or the assignment of reduced authority and responsibilities; a reduction in grantee’s base salary or target bonus by more than 10%; or a workplace relocation of more than 50 miles from grantee’s then-present work location, all subject to a notice requirement by the executive officer to Maxwell and a cure period by Maxwell.

Please see “—Table of Estimated Consideration for Equity Awards” below for additional information.

Table of Estimated Consideration for Equity Awards

Directors

The table below sets forth, for each of our non-employee directors, the aggregate number of shares of Maxwell common stock subject to Maxwell options and Maxwell Time-based RSU Awards that are held by our non-employee directors as of February 11, 2019.

64

Executive Officers

The table below sets forth, for each of our executive officers, the aggregate number of shares of Maxwell common stock subject to vested Maxwell options that are held by our executive officers as of February 11, 2019, and the aggregate number of shares of Maxwell common stock subject to unvested Maxwell options and unvested Maxwell Time-based RSU Awards, Maxwell MSUs, and Maxwell PSUs held by our executive officers as of February 11, 2019, that would accelerate upon a qualifying termination (which includes a termination without cause and other than due to the executive officer’s death or disability, or a resignation by the executive officer for good reason during a specified period, as discussed under “—Golden Parachute Compensation” further below).

65

Maxwell Severance

Employment Agreements

In connection with each of Dr. Fink and Mr. Lyle joining Maxwell in 2014 and 2015, respectively, we entered into an employment agreement with each of them that provides for certain benefits in the event of certain qualifying terminations of employment. Each of the employment agreements were amended in January 2016. Pursuant to their employment agreements, as amended, upon a termination of employment without cause other than within 30 days prior to a change in control or within 24 months after a change in control, Dr. Fink is entitled to 18 months, and Mr. Lyle to 12 months, of base salary and target bonus (payable in equal monthly installments), and each is entitled to a prorated annual incentive bonus based on actual performance, payable at the same time as similar bonuses paid to other executive officers, and to 12 months of health, dental and vision insurance of continued monthly premium reimbursements. Upon a termination of employment without cause or a resignation for good reason in each case either within 30 days prior to a change in control or within 24 months after a change in control, subject to certain notice and cure periods, Dr. Fink is entitled to a lump sum payment of 24 months, and Mr. Lyle to a lump sum payment of 18 months, of base salary and target bonus, Dr. Fink is entitled to 24 months, and Mr. Lyle to 12 months, of health, dental and vision of continued monthly premium reimbursements, and each is entitled to a prorated annual incentive bonus paid at target levels. The severance benefits under the employment agreements are conditioned on the executive officer’s agreement to a release of claims in favor of Maxwell. With respect to outstanding equity awards, each employment agreement provides for pro rata vesting of service-based awards in the event of an involuntary termination outside of the change in control period described above, and 100% vesting of the then unvested service and performance-based awards (at target) in the event of an involuntary termination during the change in control period described above. Dr. Fink’s employment agreement includes a so-called “better of” provision with respect to payments upon a change in control meaning that if any of the payments or benefits provided to him would not be deductible to Maxwell pursuant to Section 280G, then the payments will be reduced by the amount required to avoid the excise tax

66

imposed under Section 4999, provided that the after-tax amount of such payments and benefits as so reduced is greater than or equal to the after-tax amount of such payments and benefits without such reduction.

For purposes of Dr. Fink’s and Mr. Lyle’s employment agreements, “cause” generally means the executive’s (a) unauthorized use or disclosure of confidential information or trade secrets, (b) breach of any agreement between him and Maxwell, (c) material failure to comply with Maxwell’s written policies or rules that have been provided, (d) conviction of, or plea of “guilty” or “no contest” to, a felony under the laws of the United States or any State, (e) gross negligence or willful misconduct in connection with his duties and responsibilities, (f) willful continuing failure to perform assigned duties after receiving written notification of the failure from the Maxwell board of directors or (g) failure to cooperate in good faith with a governmental or internal investigation of the Maxwell or its directors, officers or employees, subject to certain notice and cure periods.

For purposes of Dr. Fink’s and Mr. Lyle’s employment agreements, “good reason” generally means (a) a change in the executive’s position with Maxwell that materially reduces his level of authority or responsibility or the assignment reduced authority and responsibilities; (b) a reduction in the executive’s base salary or target bonus level in effect immediately prior to such reduction (unless such reduction is in connection with a general across the board reduction in the compensation of the Maxwell’s management team and in such case not to exceed 10%); or (c) a relocation of the executive’s office to a location more than 50 miles from his then-present work location, subject to certain notice and cure periods.

For purposes of Dr. Fink’s and Mr. Lyle’s employment agreements, “change in control” will include the merger and generally means any person acquiring beneficial ownership of more than 50% of Maxwell’s total voting power; the sale or disposition of all or substantially all of Maxwell’s assets; or any merger or consolidation of Maxwell where Maxwell’s voting securities represent 50% or less of the total voting power of the surviving entity or its parent.

Severance and Change in Control Plan

Mr. Wiggins and Ms. Lough, who do not have an employment agreement providing similar benefits, are entitled to severance payments and benefits under the Maxwell Severance and Change in Control Plan adopted in January 2016, which provides for severance arrangements for executive officers who do not otherwise have severance arrangements. Maxwell’s Severance and Change in Control Plan provides severance payments and benefits to eligible employees who do not have employment agreements, if such employees have a termination of employment without cause or a resignation for good reason (in each case as defined in the Maxwell Severance and Change in Control Plan and which definition is summarized below), subject to certain notice and cure periods, and enhanced severance payments and benefits if such a qualifying termination of employment occurs within 30 days prior to or within 24 months following the effective date of a change in control. Upon a termination of employment without cause or a resignation for good reason during such a change in control period, an executive is entitled to a lump sum payment equal to one year of base salary and target bonus, prorated annual incentive bonus paid at target achievement, if any, for the year of termination, and 12 months of health, dental and vision insurance coverage reimbursements, and outplacement services. Upon termination of employment without cause outside of such a change in control period, the executive is entitled to 6 months of base salary and target bonus payable in monthly installments, payment of prorated annual incentive bonus based on actual performance, 12 months of health, dental and vision insurance coverage reimbursement, and outplacement services. The severance benefits under the Maxwell Severance and Change in Control Plan are conditioned on the executive officer’s agreement to a release of claims in favor of Maxwell and nondisparagement obligations in favor of Maxwell.

For purposes of the Maxwell Severance and Change in Control Plan, “cause” and “good reason” generally have the same meanings as “cause” and “good reason” as set forth in Dr. Fink’s and Mr. Lyle’s employment agreements.

67

For purposes of the Maxwell Severance and Change in Control Plan, “change in control” will include the merger and generally means any merger or consolidation in which we are not the surviving entity; the sale of all or substantially all of our assets to any other person or entity; the acquisition of beneficial ownership of a controlling (more than 50%) interest in the outstanding shares of our common stock by any person or entity; or an election of Maxwell directors as a result of which or in connection with which the persons who were directors before such election or their nominees cease to constitute a majority of the Maxwell board of directors.

Golden Parachute Compensation

In accordance with Item 402(t) of Regulation S-K, the table below sets forth the compensation that is based on or otherwise relates to the merger that will or may become payable to each of Dr. Fink, Mr. Lyle, and Mr. Wiggins, who constitute Maxwell’s named executive officers, in connection with the merger. Please see the previous portions of this section for further information regarding this compensation.

The amounts indicated in the table below are estimates of the amounts that would be payable assuming, solely for purposes of this table, that (1) the merger is consummated on March 31, 2019; (2) the employment of each of the named executive officers is terminated other than for “cause” or the named executive officer resigns for “good reason” at the effective time (as such terms are defined in his applicable employment agreement or applicable equity award agreement, in each case on that date); (3) the price per share of consideration that holders of shares of Maxwell common stock would receive in the merger is equal to $4.75, (4) the named executive officer’s base salary rate and performance bonus target amount remain unchanged from that in effect as of February 11, 2019; (5) no named executive officer receives any additional equity grants on or prior to the effective time that will vest on or prior to the effective time; and (6) no named executive officer enters into a new agreement or is otherwise legally entitled to, prior to the effective time, additional compensation or benefits. All of the payments in the table below are “double trigger” payments that require the named executive offers to terminate employment except as noted.

For a narrative description of the terms and conditions applicable to the payments quantified in the table below, see the preceding subsections. The amounts shown in the table do not include the payments or benefits that would have been earned on or prior to the effective time; or the value of payments or benefits that are not based on or otherwise related to the merger. In the footnotes to the table below, we refer to payments that are conditioned on the occurrence of both the merger as well as the termination of the named executive officer’s employment without “cause” or on account of “good reason”, if applicable, as being payable on a “double-trigger” basis.

Maxwell’s executive officers will not receive pension payments, nonqualified deferred compensation benefits or tax reimbursements in connection with the merger.

In addition to the assumptions regarding the date of completion of the merger and the termination of employment, these estimates are based on certain other assumptions that are described in the footnotes accompanying the table below. Accordingly, the ultimate values to be received by a named executive officer in connection with the merger may differ from the amounts set forth below.

Employee Stock Purchase Plan

Any Maxwell employee who is not a participant in Maxwell’s 2004 Employee Stock Purchase Plan (the “ESPP”) as of the date of the merger agreement may not become a participant in any offering periods in effect under the ESPP as of the date of the merger agreement. No participant may increase his or her contributions or payroll deductions under the ESPP after the date of the merger agreement. If the offering periods in effect as of the date

69

of the merger agreement terminate prior to the effective time, then the ESPP will be suspended and no new offering period will commence under the ESPP prior to the termination of the merger agreement. If any current ESPP offering period is still in effect at the effective time, then the last day of such current ESPP offering period will be accelerated to a date before the closing date as specified by the Maxwell board of directors or its designated committee. Subject to the consummation of the merger, the ESPP will terminate effective immediately prior to the effective time.

Rule 14d-10(d) Matters

The merger agreement provides that, prior to the acceptance time (as defined below), the compensation committee of the Maxwell board of directors will take certain actions with respect to compensation matters. The compensation committee of the Maxwell board of directors duly adopted at a meeting of the Maxwell board of directors on February 14, 2019, resolutions approving as an “employment compensation, severance or other employee benefit arrangement” within the meaning of Rule 14d-10(d)(1) under the Exchange Act (i) each arrangement related to certain payments made or to be made and certain benefits granted or to be granted according to employment compensation, severance and other employee benefit plans of Maxwell, including the Maxwell Equity Plans, to certain holders of Maxwell shares, Maxwell options, Maxwell RSU awards, (ii) the treatment of Maxwell options, Maxwell RSU awards in accordance with the terms of the merger agreement and (iii) certain provisions of the merger agreement relating to indemnification, insurance and other compensation and benefits provided to Maxwell’s directors, executive officers and employees. In addition, the compensation committee of the Maxwell board of directors will take all other actions necessary to satisfy the requirements of the non-exclusive safe harbor under Rule 14d-10(d)(2) under the Exchange Act with respect to the foregoing arrangements.

Indemnification and Insurance

Under the merger agreement, for a period of not less than six years after the effective time of the merger, Tesla must, and must cause the surviving corporation in the merger to, indemnify and hold harmless, to the fullest extent permitted under applicable law and the organizational documents of Maxwell or its subsidiaries, or any indemnification agreements in existence as of the date of the merger agreement that were provided to Tesla, each current and former director and executive officer of Maxwell and its subsidiaries against any costs and expenses in connection with any actual or threatened claims in respect of acts or omissions occurring or alleged to have occurred at or prior to the effective time of the merger, whether asserted or claimed prior to, at or after the effective time of the merger, in connection with such person serving as an executive officer, director, employee or other fiduciary of Maxwell, any of its subsidiaries or any other person if such service was at the request or for the benefit of Maxwell or any of its subsidiaries.

In addition, for a period of six years following the effective time of the merger, Tesla is required to maintain in effect the provisions in the organizational documents of Maxwell and any indemnification agreements in existence as of the date of the merger agreement that were provided to Tesla (except to the extent such agreement provides for an earlier termination) regarding elimination of liability, indemnification of executive officers, directors and employees and advancement of expenses that are in existence as of the date of the merger agreement.

At or prior to the effective time of the merger, Maxwell is required to purchase a directors’ and officers’ liability insurance and fiduciary liability insurance “tail” insurance policy for a period of six years after the effective time of the merger with respect to matters arising at or prior to the effective time of the merger, with a one-time cost not in excess of 250% of the last aggregate annual premium paid by Maxwell for its directors’ and officers’ liability insurance and fiduciary liability insurance prior to the date of the merger agreement, and if the cost of such “tail” insurance policy would otherwise exceed such amount, Maxwell may purchase as much coverage as reasonably practicable for such amount. See the section entitled “Merger Agreement—Directors’ and Officers’ Indemnification and Insurance.”

Section 16 Matters

Pursuant to the merger agreement, prior to the effective time of the merger, Maxwell and Tesla have agreed to, as applicable, take all such steps as may be reasonably necessary or advisable hereto to cause any dispositions of equity securities of Maxwell (including derivative securities) and acquisitions of equity securities of Tesla pursuant to the transactions contemplated by the merger agreement by each individual who is a director or executive officer of Maxwell subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to Maxwell to be exempt under Rule 16b-3 promulgated under the Exchange Act.

Maxwell Shares Held by Maxwell Officers and Directors

As of February 11, 2019, the directors and executive officers of Maxwell and their affiliates beneficially owned approximately 3,897,048 Maxwell shares, representing approximately 8.41% of the aggregate voting power of the Maxwell shares outstanding as of February 11, 2019.

Concurrently with the execution of the merger agreement, on February 3, 2019, (i) Maxwell board members Richard Bergman, Steven Bilodeau, Jörg Buchheim, Franz Fink, Burkhard Göschel, Ilya Golubovich, John Mutch and I2BF Energy Limited and (ii) Maxwell officers Franz Fink, David Lyle and Emily Lough, entered into a tender and support agreement with Tesla and the Offeror, solely in their capacities as stockholders of Maxwell. For more information regarding the support agreement, see the section entitled “Other Transaction Agreements—Support Agreement,” and such support agreement, which is filed as Exhibit 99.6 to this document.

Certain Relationships with Maxwell

As of the date of this document, Tesla does not own any shares of Maxwell common stock. Neither Tesla nor the Offeror has effected any transaction in securities of Maxwell in the past 60 days. To the best of Tesla’s and the Offeror’s knowledge, after reasonable inquiry, none of the persons listed on Annex C hereto, nor any of their respective associates or majority-owned subsidiaries, beneficially owns or has the right to acquire any securities of Maxwell or has effected any transaction in securities of Maxwell during the past 60 days.

Tesla and Maxwell entered into a confidentiality agreement, dated December 14, 2018, in connection with their consideration of the possible negotiated transaction that resulted in the execution of the merger agreement. Pursuant to the confidentiality agreement, subject to certain customary exceptions, Tesla and Maxwell agreed to keep confidential all non-public information received from the other party. Tesla and Maxwell also agreed that the non-public information furnished by the other party pursuant to the confidentiality agreement would be used solely for the purpose of evaluating, negotiating, executing and implementing the possible negotiated transaction. See the section entitled “Other Transaction Agreements—Confidentiality Agreement” and the confidentiality agreement, which is filed as Exhibit 99.7 to this document.

Tesla and Maxwell entered into an exclusivity and non-solicitation agreement, dated January 22, 2019, in connection with their evaluation of the potential business combination that resulted in the execution of the merger agreement. The exclusivity and non-solicitation agreement set forth certain terms on which Tesla and Maxwell would conduct negotiations regarding the potential business combination that resulted in the execution of the merger agreement. See “Other Transaction Agreements—Exclusivity and Non-Solicitation Agreement” and the exclusivity and non-solicitation agreement, which is filed as Exhibit 99.8 to this document.

Fees and Expenses

Tesla has retained Georgeson LLC as information agent in connection with the offer and the merger. The information agent may contact holders of shares by mail, email, telephone, facsimile and personal interview and may request brokers, dealers and other nominee stockholders to forward material relating to the offer and the merger to beneficial owners of shares. Tesla will pay the information agent reasonable and customary

71

compensation for these services in addition to reimbursing the information agent for its reasonable out-of-pocket expenses. Tesla agreed to indemnify the information agent against certain liabilities and expenses, including certain liabilities under the U.S. federal securities laws.

In addition, Tesla has retained Computershare Trust Company, N.A. as exchange agent in connection with the offer and the merger. Tesla will pay the exchange agent reasonable and customary compensation for its services in connection with the offer and the merger, will reimburse the exchange agent for its reasonable out-of-pocket expenses and will indemnify the exchange agent against certain liabilities and expenses, including certain liabilities under the U.S. federal securities laws.

Tesla will reimburse brokers, dealers, commercial banks and trust companies and other nominees, upon request, for customary and reasonable clerical and mailing expenses incurred by them in forwarding offering materials to their customers. Except as set forth above, neither Tesla nor the Offeror will pay any fees or commissions to any broker, dealer or other person for soliciting tenders of Maxwell shares pursuant to the offer.

Accounting Treatment

In accordance with U.S. generally accepted accounting principles, Tesla will account for the acquisition of shares through the offer and the merger under the acquisition method of accounting for business combinations.

Stock Exchange Listing

Tesla shares are listed on the Nasdaq Global Select Market under the symbol “TSLA”. Tesla intends to submit a listing of additional shares notification form to list on the Nasdaq Global Select Market the Tesla shares that Tesla will issue in the offer and merger as part of the offer consideration. Such listing is a condition to completion of the offer.

Resale of Tesla Common Stock

All Tesla shares received by Maxwell stockholders as part of the offer consideration in the offer and the merger will be freely tradable for purposes of the Securities Act, except for Tesla shares received by any person who is deemed an “affiliate” of Tesla at the time of the closing of the merger. Tesla shares held by an affiliate of Tesla may be resold or otherwise transferred without registration in compliance with the volume limitations, manner of sale requirements, notice requirements and other requirements under Rule 144 or as otherwise permitted under the Securities Act.

MERGER AGREEMENT

The following summary describes certain material provisions of the merger agreement entered into by Tesla, the Offeror and Maxwell, a copy of which is attached hereto as Annex A. This summary may not contain all of the information about the merger agreement that is important to Maxwell stockholders, and Maxwell stockholders are encouraged to read the merger agreement carefully in its entirety. The legal rights and obligations of the parties are governed by the specific language of the merger agreement and not this summary.

The Offer

The Offeror is offering to exchange each outstanding share of Maxwell common stock that has been validly tendered and not validly withdrawn in the offer for a fraction of a share of Tesla common stock equal to the quotient obtained by dividing $4.75 by the Tesla trading price, subject to the minimum. In the event that the Tesla trading price is equal to or less than $245.90, then each share of Maxwell common stock validly tendered and not validly withdrawn in the offer will be exchanged for 0.0193 of a share of Tesla common stock. Such shares of Tesla common stock plus cash in lieu of any fractional shares of Tesla common stock is referred to herein as the “offer consideration,” and the offer consideration will be paid without interest and less any applicable withholding taxes.

The Offeror’s obligation to accept for exchange Maxwell shares validly tendered (and not validly withdrawn) pursuant to the offer is subject to the satisfaction or waiver by the Offeror of certain conditions, including the condition that, prior to the expiration of the offer, there have been validly tendered and not validly withdrawn a number of Maxwell shares that, upon the consummation of the offer, together with Maxwell shares then owned by Tesla and the Offeror (if any), would represent at least a majority of the aggregate voting power of the Maxwell shares outstanding immediately after the consummation of the offer (the “minimum tender condition”), as more fully described under “The Offer—Conditions of the Offer.”

Under the merger agreement, unless Maxwell consents otherwise or the merger agreement is terminated:

73

No extension will impair, limit or otherwise restrict the right of the parties to terminate the merger agreement pursuant to its terms.

The Offeror may not terminate or withdraw the offer prior to the then-scheduled expiration of the offer unless the merger agreement is validly terminated in accordance with its terms, in which case the Offeror will terminate the offer promptly (but in no event more than one business day) after such termination. Among other circumstances, the merger agreement may be terminated by either Tesla or Maxwell if the offer shall have terminated or expired in accordance with its terms (subject to the rights and obligations of Tesla and the Offeror to extend the offer pursuant to the merger agreement) without the Offeror having accepted for payment any Maxwell shares pursuant to the offer, or if the acceptance for exchange of Maxwell shares tendered in the offer has not occurred on or before July 3, 2019 (subject to the six-business day maximum extension in certain circumstances described under “—Termination of the Merger Agreement”), which we refer to as the “outside date.” See “—Termination of the Merger Agreement.”

For a more complete description of the offer, see the section entitled “The Offer.”

The Merger

The merger agreement provides that, if the offer is completed, the parties will effect the merger of the Offeror with and into Maxwell, with Maxwell continuing as the surviving corporation in the merger, and the former Maxwell stockholders will not have any direct equity ownership interest in the surviving corporation.

Completion and Effectiveness of the Merger

Under the merger agreement, the closing of the merger must occur promptly, and in any case no later than the second business day, after the acceptance of tendered Maxwell shares in the offer and the satisfaction of the other condition to the merger, unless the parties agree otherwise in writing (see “—Conditions to the Merger”). The merger will become effective upon the filing of a certificate of merger with the Secretary of State of the State of Delaware unless a later date is specified therein.

Offer Consideration Payable Pursuant to the Merger

In the merger, except as provided below, each outstanding Maxwell share that was not acquired by the Offeror in the offer will be converted into the right to receive the offer consideration, without interest and less any applicable withholding taxes.

In the merger, Maxwell shares that are owned or held in treasury by Maxwell or owned by Tesla or the Offeror will be cancelled without any consideration being delivered. In the merger, Maxwell shares that are owned by any wholly-owned subsidiary of Tesla (other than the Offeror) or of Maxwell will be converted into shares of common stock of the surviving corporation based on a formula described in the merger agreement.

Fractional Shares

Tesla will not issue fractional shares of Tesla common stock in the offer or the merger. Instead, each holder of Maxwell shares who otherwise would be entitled to receive fractional shares of Tesla common stock will be entitled to an amount of cash (without interest) equal to such fractional part of a share of Tesla common stock multiplied by the Tesla trading price, rounded down to the nearest cent; however, if the Tesla trading price is equal to or less than $245.90, each holder of Maxwell common stock who otherwise would be entitled to receive fractional shares of Tesla common stock will be entitled to an amount of cash (without interest) equal to such fractional part of a share of Tesla common stock multiplied by $245.90. rounded down to the nearest cent.

74

Exchange of Maxwell Stock Certificates or Book-Entry Shares for the Offer Consideration

Tesla has retained Computershare Trust Company, N.A. as the depositary and exchange agent for the offer and the merger to handle the exchange of Maxwell shares for the offer consideration.

To effect the exchange of Maxwell shares that were converted into the right to receive the offer consideration, within two business days after the effective time of the merger, the exchange agent will mail to each record holder of Maxwell shares a form of transmittal and instructions for surrendering the stock certificates or book-entry shares that formerly represented Maxwell shares for the offer consideration. No holder of book-entry Maxwell shares will be required to deliver a certificate or letter of transmittal or surrender such book-entry Maxwell shares to the exchange agent to receive the offer consideration in the merger. Each record holder of Maxwell shares will be entitled to receive the offer consideration (including cash in lieu of any fractional shares of Tesla common stock), and the payment of any dividends or other distributions, without interest,

in each case, which prior to proper exchange of such Maxwell shares had become payable with respect to the Tesla common stock issuable as stock consideration in respect of such Maxwell shares.

No interest will be paid or will accrue on any portion of the offer consideration payable in respect of any Maxwell share.

After the effective time of the merger, each stock certificate or book-entry share formerly representing shares of Maxwell common stock that has not been surrendered will represent only the right to receive upon such surrender the offer consideration to which such holder is entitled by virtue of the merger and any dividends or other distributions payable to such holder upon such surrender.

Conditions to the Merger

If the offer is completed, the respective obligations of each party to effect the merger are subject to the satisfaction or waiver of the following two conditions:

Representations and Warranties

The merger agreement contains customary representations and warranties of the parties. These include representations and warranties of Maxwell with respect to:

75

The merger agreement also contains customary representations and warranties of Tesla and the Offeror, including among other things:

76

Certain of the representations and warranties contained in the merger agreement are qualified by “material adverse effect” (as defined in the merger agreement and described below). The representations and warranties contained in the merger agreement will expire at the effective time of the merger. The representations, warranties and covenants made by Maxwell in the merger agreement are qualified by information contained in the confidential disclosure schedules delivered to Tesla in connection with the execution of the merger agreement and by filings that Maxwell has made with the SEC prior to the date of the merger agreement. The representations, warranties and covenants made by Tesla and the Offeror in the merger agreement are qualified by information contained in the confidential disclosure schedules delivered to Maxwell in connection with the execution of the merger agreement and by filings that Tesla has made with the SEC prior to the date of the merger agreement. Stockholders are not third-party beneficiaries of these representations, warranties and covenants under the merger agreement and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of Maxwell or any of its affiliates or of Tesla or any of its affiliates.

Material Adverse Effect

A “material adverse effect” with respect to Tesla or Maxwell, means any change, effect, development, circumstance, condition, fact, state of facts, event or occurrence that, individually or in the aggregate, has had or would reasonably be expected to have a material adverse effect on the financial condition, business, assets or operations of such party and its subsidiaries, taken as a whole, except that no such change, effect, development, circumstance, condition, fact, state of facts, event or occurrence resulting or arising from any of the following will be deemed to constitute a material adverse effect or will be taken into account when determining whether a material adverse effect exists or has occurred or is reasonably expected to exist or occur:

77

provided that with respect to the exceptions in clauses (a), (b), (c), (d), (e) and (g) above, if such change, effect, development, circumstance, condition, fact, state of facts, event or occurrence has had a disproportionate adverse impact on such party relative to other companies operating in the industry or industries in which such party operates, then the incremental disproportionate adverse impact of such change, effect, development, circumstance, condition, fact, state of facts, event or occurrence will be taken into account for the purpose of determining whether a “material adverse effect” exists or has occurred.

No Solicitation of Other Offers by Maxwell

Under the terms of the merger agreement, subject to certain exceptions described below, Maxwell has agreed that, from the date of the merger agreement until the earlier of the acceptance time or the date (if any) the merger agreement is terminated, Maxwell and its board of directors (including any committee of its board of directors) will not and Maxwell will not and will cause its controlled affiliates not to, and Maxwell will not authorize or permit its and its controlled affiliates’ respective directors, officers, employees and other representatives to, directly or indirectly:

78

We refer to the actions set forth in clauses (c), (d), (e), (f), (g) and (h) (to the extent related to the foregoing clauses (c), (d), (e), (f) or (g)) above as a “change of recommendation.”

In addition, under the merger agreement, Maxwell has agreed that:

Under the merger agreement, Maxwell has agreed to enforce, and not waive, terminate or modify without Tesla’s prior written consent, any confidentiality, standstill or similar provision in any confidentiality, standstill or other agreement; provided that, if the Maxwell board of directors determines in good faith after consultation with Maxwell’s outside legal counsel that the failure to waive a particular standstill provision would reasonably be expected to be a breach of the directors’ fiduciary duties under applicable law, Maxwell may, with prior written notice to Tesla, waive such standstill solely to the extent necessary to permit the applicable person (if Maxwell has not breached its non-solicitation obligations) to make, on a confidential basis to the Maxwell board of directors, an acquisition proposal, conditioned upon such person agreeing to disclosure of such acquisition proposal to Tesla, in each case as contemplated by the merger agreement.

Notwithstanding the prohibitions described above, if Maxwell receives, prior to the acceptance time, a bona fide written acquisition proposal that did not result from a breach of Maxwell’s non-solicitation obligations, Maxwell

79

is permitted to furnish non-public information to such person and engage in discussions or negotiations with such person and its representatives with respect to the acquisition proposal, as long as:

Under the merger agreement, Maxwell is obligated to notify Tesla promptly (and in any event within 24 hours) of any receipt by any director or officer of Maxwell or by any of Maxwell’s controlled affiliates or its or their respective representatives of any acquisition proposal or any proposals or inquiries that could reasonably be expected to lead to an acquisition proposal, or any inquiry or request for non-public information relating to Maxwell or any Maxwell subsidiary by any person who has made or could reasonably be expected to make any acquisition proposal (or of becoming aware of any of its or their other affiliates having received any such acquisition proposal, proposal, inquiry or request). The notice must include the identity of the person making the acquisition proposal, inquiry or request (unless prohibited by the terms of an existing confidentiality agreement), and the material terms and conditions of any such proposal or offer or the nature of the information requested pursuant to any such inquiry or request, including unredacted copies of all written requests, proposals or offers (including any proposed agreements received by Maxwell) or, if such acquisition proposal is not in writing, a reasonably detailed written description of the material terms and conditions thereof (provided that Maxwell may withhold the identity of the person making the acquisition proposal if prohibited by the terms of an existing confidentiality agreement). Maxwell also must keep Tesla reasonably informed on a prompt and timely basis of the status and material terms (including any amendments or proposed amendments to such material terms) of any such acquisition proposal or potential acquisition proposal, and as to the nature of any information requested of Maxwell with respect thereto. Maxwell also has agreed to promptly provide (and in any event within the earlier of 48 hours and one business day) Tesla with any material non-public information concerning Maxwell provided to any other person in connection with any acquisition proposal that was not previously provided to Tesla. Without limiting the foregoing, Maxwell has agreed to promptly (and in any event within 24 hours after such determination) inform Tesla in writing if Maxwell determines to begin providing information or to engage in discussions or negotiations concerning an acquisition proposal to the extent otherwise permitted by the merger agreement.

The “acceptance time” for purposes of the merger agreement is the time that the Offeror accepts for payment all Maxwell shares that are validly tendered and not validly withdrawn pursuant to the offer promptly after the expiration of the offer (as it may be extended pursuant to the terms of the merger agreement) or, at Tesla’s election, concurrently with the expiration of the offer if all conditions to the offer have been satisfied or waived in accordance with the merger agreement.

An “acquisition proposal” for purposes of the merger agreement means any offer, proposal or indication of interest from any person or group (as defined in Section 13(d) of the Exchange Act), other than a proposal or

80

offer by Tesla or a subsidiary of Tesla, at any time relating to any transaction or series of related transactions involving:

A “superior proposal” for purposes of the merger agreement means a bona fide, written acquisition proposal by a third party which the Maxwell board of directors determines in good faith (after consultation with Maxwell’s outside legal counsel and financial advisors) to be more favorable to Maxwell’s stockholders from a financial point of view than the offer and the merger, taking into account all relevant factors, including all the terms and conditions of such proposal or offer (including conditionality, offer consideration, timing, certainty of financing and/or regulatory approvals and likelihood of consummation) and the merger agreement, as well as any changes to the terms of the merger agreement proposed by Tesla in response to any acquisition proposal. However, in determining whether an acquisition proposal constitutes a superior proposal, the Maxwell board of directors is not entitled to take into account the difference, in and of itself, of the form of consideration between Tesla common stock and any cash offered in any such acquisition proposal, but may take into account the difference in value between Tesla common stock and any cash offered in any such acquisition proposal. When determining whether an offer constitutes a superior proposal, references in the term “acquisition proposal” to “15%” or “85%” will be replaced with references to “100%” and “0%”, respectively.

Change of Recommendation; Match Rights

The merger agreement requires the Maxwell board of directors to recommend that Maxwell stockholders accept the offer and tender their Maxwell shares into the offer. However, prior to the acceptance time:

Prior to making a change of recommendation for any reason set forth above, Maxwell must provide Tesla five business days’ prior written notice advising Tesla that it intends to make a change of recommendation. The notice must specify in reasonable detail the reasons for such change of recommendation due to an intervening

81

event (as defined below), or the material terms and conditions of the acquisition proposal (including a copy of any proposed definitive agreement) for any change of recommendation due to a superior proposal. In each case, Maxwell must cause its representatives (including its executive officers) to be available during such five business day period to negotiate in good faith (to the extent Tesla desires to negotiate) any proposal by Tesla to amend the merger agreement in a manner that would eliminate the need for the Maxwell board of directors to make a change of recommendation in the case of an intervening event or that would cause such acquisition proposal to no longer be a superior proposal in the case of a superior proposal, and the Maxwell board of directors must again make the required determination regarding its fiduciary duties at the end of such five business day negotiation period (after in good faith taking into account the amendments to the merger agreement proposed by Tesla). With respect to any change of recommendation in response to a superior proposal, if there is any material amendment, revision or change to the terms of the then-existing superior proposal (including any revision to the amount, form or mix of consideration proposed to be received by Maxwell’s stockholders as a result of such superior proposal), Maxwell must again comply with the obligations described in this paragraph.

An “intervening event” for purposes of the merger agreement is any event, change or development first occurring or arising after the date of the merger agreement that is material to Maxwell and its subsidiaries, taken as a whole, and was not known by or reasonably foreseeable to the Maxwell board of directors as of or prior to the date of the merger agreement, except that in no event will the following events, changes or developments constitute an “intervening event”: (a) the receipt, existence or terms of an acquisition proposal or any matter relating thereto or consequence thereof; (b) changes in the market price or trading volume of the Maxwell common stock, the Tesla common stock or any other securities of Maxwell, Tesla or their respective subsidiaries, or any change in credit rating or the fact that Maxwell meets or exceeds (or that Tesla fails to meet or exceed) internal or published estimates, projections, forecasts or predictions for any period; (c) changes in general economic, political or financial conditions or markets (including changes in interest rates, exchange rates, stock, bond and/or debt prices); (d) changes in GAAP, other applicable accounting rules or applicable law or, in any such case, changes in the interpretation thereof; (e) general changes or developments in any of the industries in which Maxwell or its subsidiaries operate; (f) natural disasters or calamities; (g) any outbreak or escalation of armed hostilities, any acts of war or terrorism; (h) the announcement or pendency of the merger agreement and the transactions contemplated thereby; or (i) any litigation brought by or on behalf of any current or former Maxwell stockholder (in its capacity as such) arising from allegations of any breach of fiduciary duty relating to the merger agreement (or the transactions contemplated thereby) or violation of securities law related to the Schedule TO, the other offer documents, the Schedule 14D-9 or any other document required to be filed with the SEC by the Maxwell or required to be distributed or otherwise disseminated to the Maxwell’s stockholders in connection with the offer and the merger.

Nothing in the merger agreement prohibits Maxwell or the Maxwell board of directors from disclosing to Maxwell’s stockholders a position contemplated by Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act or making any “stop, look and listen” communication to Maxwell’s stockholders pursuant to Rule 14d-9(f) promulgated under the Exchange Act, or any similar statement in response to any publicly disclosed acquisition proposal, provided that any such “stop, look and listen” statement, or any such similar statement, also includes an express reaffirmation of the Maxwell board of directors’ recommendation that Maxwell stockholders accept the offer and tender their Maxwell shares into the offer.

Conduct of Business Before Completion of the Merger

Restrictions on Maxwell’s Operations

The merger agreement provides for certain restrictions on Maxwell’s and its subsidiaries’ activities until the earlier of the effective time of the merger or the date (if any) the merger agreement is terminated. In general, except as specifically permitted or required by the merger agreement, as required by applicable law or as consented to in writing by Tesla (which may not be unreasonably withheld, conditioned or delayed), subject to specified exceptions set forth in the merger agreement, Maxwell and each of its subsidiaries is required to

82

conduct its business in all material respects in the ordinary course of business consistent with past practice and use commercially reasonable efforts to preserve intact its and their present business organizations, goodwill and ongoing business, keep available the services of its and their present officers and other key employees (except other than where such termination is for cause) and preserve its and their present relationships with customers, suppliers, vendors, licensors, licensees, governmental entities, employees and other persons with whom it and they have material business relations. In addition, except as specifically permitted or required by the merger agreement, as required by applicable law or the rules and regulations of the SEC or Nasdaq or as consented to in writing by Tesla (which, in certain cases, may not be unreasonably withheld, conditioned or delayed), subject to specified exceptions set forth in the merger agreement, Maxwell must not and must not permit any of its subsidiaries to, directly or indirectly:
