In the following pages of this Proxy Statement, you will find information on your Board of Directors, the candidates for election to the Board, and three other agenda items to be voted upon at the Annual Meeting of Stockholders (the “Meeting”) and any adjournment or postponement of that Meeting. The background information in this Proxy Statement has been supplied to you at the request of the Board of Directors to help you decide how to vote and to provide information on the Company’s corporate governance and compensation practices. References in this document to the Company and Dow mean The Dow Chemical Company. This Proxy Statement is first being distributed to stockholders on or about March 28, 2013.

Vote Your Shares in Advance

You may vote your shares through the Internet, by telephone or by signing and returning the enclosed proxy or other voting form. Your shares will be voted if the voting form is properly executed and received by the independent Inspector of Election prior to the Meeting. If no specific choices are made by you when you execute your voting form, as explained on the form, your shares will be voted as recommended by your Board of Directors.

You may revoke your voting instructions at any time before its use at the Meeting by sending a written revocation, by submitting another proxy or voting form on a later date, or by attending the Meeting and voting in person. No matter which voting method you choose, however, you should not vote any single account more than once unless you wish to change your vote. Be sure to submit votes for each separate account in which you hold Dow shares.

Confidential Voting

The Company has a long-standing policy of vote confidentiality. Proxies and ballots of all stockholders are kept confidential from the Company’s management and Board unless disclosure is required by law and in other limited circumstances. The policy further provides that employees may confidentially vote their shares of Company stock held by the Company’s employees’ savings plans, and requires the appointment of an independent tabulator and inspector of election for the Meeting.

Dividend Reinvestment Plan Shares and Employees’ Savings Plans Shares

If you are enrolled in the dividend reinvestment plan (“DRP”), the shares of common stock owned on the record date by you directly, plus all shares of common stock held for you in the DRP, will appear together on a single voting form. The DRP administrator, Computershare Trust Company, N.A., will vote all shares of stock held in your DRP account as directed by you only if you return your proxy form. If no specific instruction is given on an executed proxy form, the DRP administrator will vote as recommended by your Board of Directors.

Participants in various employees’ savings plans, including The Dow Chemical Company Employees’ Savings Plan (each a “Plan” or the “Plans”), will receive, as appropriate, a confidential voting instruction form. Your executed form will provide voting instructions to the respective Plan Trustee. If no instructions are provided, the Trustees will vote the respective Plan shares according to the provisions of each Plan.

To allow sufficient time for voting by the Trustees and/or administrators of the Plans, your voting instructions must be received by 11:59 p.m. Eastern Time on May 6, 2013.

Dow Shares Outstanding and Quorum

At the close of business on the record date, March 18, 2013, there were 1,208,129,785 shares of Dow common stock outstanding and entitled to vote. Each share of common stock is entitled to one vote. There were 4,000,000 shares of Series A Cumulative Convertible Perpetual Preferred Stock outstanding; however, no such shares of preferred stock outstanding as of the record date are entitled to vote. The holders of at least 50% of the issued and outstanding shares of common stock entitled to vote that are present in person or represented by proxy constitutes a quorum for the transaction of business at the Meeting. Abstentions and broker non-votes will be included in determining the presence of a quorum at the Meeting. Broker non-votes occur when a person holding shares in street name, meaning through a brokerage firm, does not provide instructions as to how to vote their shares and the broker is not permitted to exercise voting discretion. Under New York Stock Exchange rules, your

broker may vote shares held in street name on the Ratification of the Appointment of the Independent Registered Public Accounting Firm without instruction from you, but may not vote on any other matter to be voted on at the Annual Meeting without instruction from you.

Proxies on Behalf of the Dow Board

Your Board of Directors is soliciting proxies to provide an opportunity to all stockholders of record to vote on agenda items, whether or not the stockholders are able to attend the Meeting or an adjournment or postponement thereof. Proxies may be solicited on behalf of the Board in person,

by mail, by telephone or by electronic communication by Dow officers and employees. The proxy representatives of the Board of Directors will not be specially compensated for their services in this regard.

Dow has retained D. F. King & Co., Inc. to aid in the solicitation of stockholders (primarily brokers, banks and other institutional investors) for an estimated fee of $50,000, plus out-of-pocket expenses. Arrangements have been made with brokerage houses, nominees and other custodians and fiduciaries to send materials to their principals, and their reasonable expenses will be reimbursed on request. The cost of solicitation will be borne by the Company.

In accordance with the recommendation of the Governance Committee, the Board of Directors has nominated Arnold A. Allemang, Ajay Banga, Jacqueline K. Barton, James A. Bell, Jeff M. Fettig, Andrew N. Liveris, Paul Polman, Dennis H. Reilley, James M. Ringler and Ruth G. Shaw for election as Directors, to serve for a one-year term that expires at the Annual Meeting in 2014, and until their successors are elected and qualified. John B. Hess is not standing for re-election at the Annual Meeting, and the Board thanks him for his exemplary service to the Company.

Each nominee is currently serving as a Director and each has consented to serve for the new term. Director Ajay Banga joined the Board following the 2012 Annual Meeting having been elected by the Board to serve as a Director effective February 15, 2013. Mr. Banga was recommended for nomination as a Director by the Company’s Chairman and several independent Directors. All other nominees have previously been elected as Directors by the Company’s stockholders. Information in the biographies below is current as of February 18, 2013. Please see pages 15 to 17 for additional information on “Director Qualifications and Diversity.”

The Board of Directors unanimously recommends a vote FOR the election of ALL of these nominees as Directors.

The Company’s Bylaws prescribe the voting standard for election of Directors as a majority of the votes cast in an

uncontested election, such as this one, where the number of nominees does not exceed the number of Directors to be elected. Under this standard, a nominee must receive more “for” than “against” votes to be elected. Abstentions and broker non-votes are not included. Under the Company’s Corporate Governance Guidelines, if a nominee who already serves as a Director is not elected, that nominee shall offer to tender his or her resignation to the Board. The Governance Committee will then recommend to the Board whether to accept or reject the resignation, or whether other action should be taken. Within 90 days of the certification of election results, the Board will publicly disclose its decision regarding whether to accept or reject the resignation. As explained on the accompanying proxy, it is the intention of the persons named as proxies to vote executed proxies “for” the candidates nominated by the Board unless voting instructions are provided. If something unanticipated should occur prior to the Annual Meeting making it impossible for one or more of the candidates to serve as a Director, votes will be cast in the best judgment of the persons authorized as proxies.

The New York Stock Exchange rules do not permit brokers discretionary authority to vote in the election of directors. Therefore, if you hold your shares of Company common stock in street name and do not provide voting instructions to your broker, your shares will not be voted in the election of directors. We urge you to promptly provide voting instructions to your broker to ensure that your shares are voted on this matter. Please follow the instructions set forth in the voting information provided by your bank or broker.

Corporate Governance Guidelines

The Company has adopted Corporate Governance Guidelines that are available at www.DowGovernance.com. Stockholders may receive a printed copy of the Corporate Governance Guidelines without charge by contacting the Office of the Corporate Secretary.* These Guidelines were adopted by the Board of Directors in order to set forth key areas of importance in Dow corporate governance.

The Board of Directors

The ultimate authority to oversee the business of The Dow Chemical Company rests with the Board of Directors. The role of the Board is to effectively govern the affairs of the Company for the benefit of its stockholders and, to the extent appropriate under Delaware corporation law, other constituencies including employees, customers, suppliers and communities in which it does business. Among other duties, the Board appoints the Company’s officers, assigns to them responsibility for management of the Company’s operations, and reviews their performance.

Director Independence

The Board has assessed the independence of each non-employee Director based upon the Company’s Director independence standards listed on the Company’s corporate governance website (www.DowGovernance.com). These standards incorporate the criteria in the listing standards of the New York Stock Exchange, as currently in effect, as well as additional, more stringent criteria established by the Board. Based upon these standards, the Board has determined that the following members of the Board are independent: Directors Banga, Barton, Bell, Fettig, Hess, Polman, Reilley, Ringler and Shaw. These independent Directors constitute a substantial majority of the Board, consistent with Board policy. In addition, the Board determined that the following members of the Board serving during 2012 were independent at the time they served as directors: Barbara H. Franklin and Paul D. Stern, who retired from the Board in May 2012.

When assessing independence, the Governance Committee and the Board consider all relationships between the Directors and the Company, including commercial, industrial, banking, consulting, legal, accounting, charitable and familial relationships, among others. The Company screens for such relationships using an annual Directors and Officers Questionnaire that requires disclosure of any transactions with the Company in which the Director or executive officer, or any member of his or her immediate family, has a direct or indirect material interest. Given the

large size of our Company and its diverse commercial and geographic markets, there are times when Dow sells products to, or purchases products or services from, other companies for which Dow Directors serve as executive officers or directors. The Governance Committee and the Board took into account the fact that Messrs. Bell, Fettig, Hess and Polman served as executive officers during all or a portion of the past three years of entities with which Dow made purchases or sales. All such purchases and sales were made at arms-length, commercial terms, and the Directors did not personally benefit from such transactions. In all instances, the extent of business represented significantly less than 2% of Dow’s and the other entity’s revenues. In fact, in all cases the amounts were below 0.3%. With respect to Boeing there were no purchases in 2011 or 2012, and with respect to Hess there were no sales in 2012, while with respect to Whirlpool and Unilever there were sales to and purchases from each entity which in all cases were below the 0.3% amount referenced above.

Board Leadership Structure

Since 2006, Andrew N. Liveris has served as the Chairman, Chief Executive Officer, and President of the Company. Jeff M. Fettig has served as the Lead Director since May 2011.

The Board recognizes that the leadership structure and combination or separation of the CEO and Chairman roles is driven by the needs of the Company at any point in time. The leadership structure at the Company has varied over time and has included combined roles, election of a presiding or lead director, separation of roles, and other transition arrangements for succession planning. As a result, no policy exists requiring combination or separation of leadership roles and the Company’s governing documents do not mandate a particular structure. This has allowed the Board the flexibility to establish the most appropriate structure for the Company at any given time.

The Board has determined that the Company and its stockholders are currently best served by having one person serve as Chairman and CEO as it allows for a bridge between the Board and management and provides critical leadership for carrying out the Company’s strategic initiatives and confronting its challenges. Mr. Liveris’ service as Chairman facilitates the Board decision-making process because Mr. Liveris has first-hand knowledge of the Company’s operations and the major issues facing the Company, and he chairs the Board meetings where the Board discusses strategic and business issues. Mr. Liveris is the only member of executive management who is also a Director.

As part of the decision to elect Mr. Liveris as Chairman, the independent Directors on the Board elected a Lead Director with clearly defined leadership authority and responsibilities. Mr. Fettig currently serves as Lead Director. Among other responsibilities, the Lead Director works with the Chairman to call Board meetings, set the Board agenda and determine the appropriate materials to be provided to the Directors. He leads executive sessions of the Board and other meetings at which the Chairman is not present, has the authority to call meetings of the independent directors, facilitates communication between the Board and management, and serves as focal point for stockholder communications and requests for consultation addressed to independent directors. The Lead Director may retain outside professionals on behalf of the Board as the Board may determine is necessary and appropriate. Contact information for the Lead Director is shown below under “Communication with Directors.”

The election of Mr. Liveris as both Chairman and CEO promotes unified leadership and direction for the Board and executive management. The appointment of the Lead Director and the use of executive sessions of the Board, along with the Board’s strong committee system and substantial majority of independent Directors, allows the Board to maintain effective risk oversight and provides that independent Directors oversee such critical items as the Company’s financial statements, executive compensation, the selection and evaluation of Directors, and the development and implementation of our corporate governance programs.

Risk Oversight

The Board of Directors is responsible for overseeing the overall risk management process for the Company. Risk management is considered a strategic activity within the Company and responsibility for managing risk rests with executive management while the Committees of the Board and the Board as a whole participate in the oversight of the process. Specifically, the Board has responsibility for overseeing the strategic planning process and reviewing and monitoring management’s execution of the corporate and business plan and each Board Committee is responsible for oversight of specific risk areas relevant to the Committee charters.

The oversight responsibility of the Board and Committees is enabled by an enterprise risk management model and process implemented by management that is designed to identify, assess, manage and mitigate risks. The Audit Committee is responsible for overseeing that management implements and follows this risk management process and for coordinating the outcome of reviews by the other

Committees in their respective risk areas. In addition, the enterprise risk management model and process are reviewed with the Board of Directors annually and the Board recognizes that risk management and oversight comprise a dynamic and continuous process.

The strategic plan and critical issues and opportunities are presented to the Board each year by the CEO and senior management. Throughout the year, management reviews any critical issues and actual results compared to plan with the Board and relevant Committees. Members of executive management are also available to discuss the Company’s strategy, plans, results and issues with the Committees and the Board, and regularly attend such meetings to provide periodic briefings and access. In addition, as noted in the Audit Committee Report on page 52, the Audit Committee regularly meets in executive sessions and holds separate executive sessions with the lead client service partner of the independent registered public accounting firm, internal auditor, general counsel and other management as appropriate.

The Committees undertake numerous risk oversight activities related to their charter responsibilities. For example, the Compensation and Leadership Development Committee regularly reviews any potential risks associated with the Company’s compensation policies and practices (see “Compensation Program Risk Analysis” on page 32 of this Proxy Statement). As another, the Environment, Health, Safety and Technology Committee regularly reviews the Company’s operational risks including those risks associated with process and product safety, public policy, and reputation risks.

Communication with Directors

Stockholders and other interested parties may communicate directly with the full Board, the Lead Director, the non-management Directors as a group, or with specified individual Directors by any of several methods. These methods of communication include mail addressed to The Dow Chemical Company, 2030 Dow Center, Midland, MI 48674, and the “Contact Us” feature of Dow’s corporate governance website at www.DowGovernance.com. The Lead Director and other non-management Directors may also be contacted by email addressed to LeadDirector@Dow.com. Please specify the intended recipient(s) of your letter or electronic message. Communications will be distributed to any or all Directors as appropriate depending upon the individual communication. However, the Directors have requested that communications that do not directly relate to their duties and responsibilities as Directors of the Company be excluded from distribution and deleted from email that they

access directly. Such excluded items include “spam”; advertisements; mass mailings; form letters and email campaigns that involve unduly large numbers of similar communications; solicitations for goods, services, employment or contributions; surveys; and individual product inquiries or complaints. Additionally, communications that appear to be unduly hostile, intimidating, threatening, illegal or similarly inappropriate will also be screened for omission by the Office of the Corporate Secretary. Any omitted or deleted communication will be made available to any Director upon request.

Board and Committee Meetings; Annual Meeting Attendance

There were seven Board meetings in 2012 and 23 formal Board Committee meetings. All of the Directors attended more than 75% of the sum of the total number of Board meetings and the total number of meetings of the Board Committees on which the Director served during the past year, and all but one had 100% attendance at the six regularly scheduled Board meetings. The Directors are encouraged to attend all Annual Meetings of Stockholders, and in 2012 ten of the twelve Directors then serving attended. Mr. Polman was unable to attend due to a conflict with the annual general meetings of Unilever PLC and Unilever N.V. (the entities for which he serves as chief executive officer). Ms. Franklin was unable to attend due to a family emergency.

Executive Sessions of Directors

The non-management Directors meet in executive session, chaired by the Lead Director (currently Mr. Fettig), in connection with each regularly scheduled meeting of the Board, and at other times as they may determine appropriate. In 2012, there were six executive sessions of the Board of Directors. The Audit, Compensation and Leadership Development, and Governance Committees of the Board typically meet in executive session in connection with every Committee meeting.

Board Committees

Board Committees perform many important functions. The responsibilities of each Committee are stated in the Bylaws and in their respective Committee charters, which are available at www.DowGovernance.com. Stockholders may receive a printed copy of the Committee charters without charge by contacting the Office of the Corporate Secretary.* The Board, upon the recommendation of the Governance Committee, elects members to each Committee and has the authority to change Committee chairs, memberships and the responsibilities of any Committee. A brief description of the current standing Board Committees follows, with memberships listed as of March 18, 2013, the record date for the Meeting. The Audit Committee, Compensation and Leadership Development Committee, and Governance Committee are comprised entirely of independent Directors who meet the applicable independence requirements of the New York Stock Exchange, the U.S. Securities and Exchange Commission (as applicable) and the Company.

Board of Directors’ Terms

Dow’s Restated Certificate of Incorporation provides that all Directors stand for election at each Annual Meeting of Stockholders.

Director Qualifications and Diversity

There are certain minimum qualifications for Board membership that Director candidates should possess, including strong values and discipline, high ethical standards, a commitment to full participation on the Board and its Committees, relevant career experience, and a commitment to ethnic, racial and gender diversity. The Governance Committee has adopted guidelines to be used in evaluating candidates for Board membership in order to ensure a diverse and highly qualified Board of Directors. In addition to the characteristics mentioned above, the guidelines provide that candidates should possess individual skills, experience and demonstrated abilities that help meet the current needs of the Board and provide for diversity of membership, such as experience or expertise in some of the following areas: the chemical industry, global business, science and technology, finance and/or economics, corporate governance, public affairs, government affairs, and experience as chief executive officer, chief operating officer or chief financial officer of a major company. Other factors that are considered include independence of thought, willingness to comply with Director stock ownership guidelines, meeting applicable Director independence standards (where independence is desired) and absence of conflicts of interest. The Governance Committee may modify the minimum qualifications and evaluation guidelines from time to time as it deems appropriate. These guidelines for Director qualifications are included in Dow’s Corporate Governance Guidelines, available at www.DowGovernance.com.

The guidelines for Director qualifications provide that a commitment to diversity is a consideration in the identification and nomination of Director candidates. The Governance Committee and the full Board implement and assess the effectiveness of these guidelines and the commitment to diversity by referring to these guidelines in the review and discussion of Board candidates when assessing the composition of the Board and by including questions regarding the diversity of the Board membership in the Board’s annual self-evaluations.

The Governance Committee and the Board believe that the qualifications, skills and attributes set forth generally above for all Directors and more specifically below for each of the Directors, support the conclusion that these individuals are qualified to serve as Directors of the Company and collectively possess a variety of skills, professional

experience, and diversity of backgrounds allowing them to effectively oversee the Company’s business. As noted below, the Directors have a diverse combination of the following background and qualifications: leadership experience (including current and former chief executive officer, chief financial officer and other senior executive management positions) at major domestic and foreign companies with global operations in a variety of relevant fields and industries; experience on other public company boards (including chair positions); board or other significant experience with academic, research and philanthropic institutions and trade and industry organizations; and prior government or public policy experience. The Governance Committee and Board have determined that all of the Directors nominated for election meet the personal and professional qualifications identified in this section. Listed below are several of these key attributes as they apply to the individual Directors to support the conclusion that these individuals are highly qualified to serve on the Company’s Board of Directors. Please see pages 7 to 10 for the complete biographies for each of the nominees.

Recommendations and Nominations for Director

Among the Governance Committee’s most important functions is the selection of Directors. The Committee has a long-standing practice of accepting stockholders’ suggestions of candidates to consider as potential Board members, as part of the Committee’s periodic review of the size and composition of the Board and its Committees. Such recommendations should be sent to the Governance Committee through the Corporate Secretary.*

Under the Company’s Bylaws, stockholders wishing to formally nominate a person for election as a Director at the next Annual Meeting must notify the Corporate Secretary* between the close of business on November 28, 2013, and the close of business on January 27, 2014. However, different deadlines apply if the annual meeting is called for a date that is not within 30 days before or after the anniversary of the prior year’s annual meeting. Such notices must comply with the provisions set forth in the Bylaws. A copy of the Bylaws may be found on the Company’s website at www.DowGovernance.com. Alternatively, a copy of the Bylaws will be provided without charge to any stockholder who requests it in writing. Such requests should be addressed to the Corporate Secretary.*

The Governance Committee has adopted a process for identifying new Director candidates. Recommendations may be received by the Committee from various sources, including current or former Directors, a search firm retained by the Committee, stockholders, Company executives, and by self-nomination. The Governance Committee uses the same process to evaluate Director nominees recommended by stockholders as it does to evaluate nominees identified by other sources.

The evaluation of new Director candidates involves several steps, not necessarily taken in any particular order. A preliminary analysis of a nominee involves securing a resume and other background data and comparing this data to the Director attributes outlined above, as well as to the current needs of the Board for new members including considerations to ensure diversity of membership in accordance with the guidelines identified above. References are checked and analyses are performed to identify potential conflicts of interest and appropriate independence from the Company. Candidate information is provided to all Governance Committee members for purposes of discussion and evaluation. If the Committee decides to further evaluate a candidate, interviews are conducted. Other steps may include requesting additional data from the candidate, providing Company background information to the candidate, and determining the candidate’s schedule compatibility with Dow Board and Committee meeting dates.

Code of Business Conduct

All Directors, officers and employees of Dow are expected to be familiar with the Company’s Code of Business Conduct, and to apply it in the daily performance of their Dow responsibilities. The Code of Business Conduct is intended to focus employees, officers and Directors on our corporate values of integrity and respect for people, help them recognize and make informed decisions on ethical issues, help create a culture of the highest ethical and business standards, and provide mechanisms to report unethical conduct. The full text of Dow’s Code of Business Conduct is available at www.DowGovernance.com. Stockholders may receive a printed copy of the Code of Business Conduct without charge by contacting the Office of the Corporate Secretary.* In addition, we will disclose on our website any waiver of or amendment to our Code of Business Conduct requiring disclosure under applicable rules.

Certain Transactions and Relationships

The Federal securities laws require public companies to describe any transaction, since the beginning of the last fiscal year, or any currently proposed transaction, in which the Company was or is to be a participant and the amount involved exceeds $120,000, and in which any related person had or will have a direct or indirect material interest. Related persons are directors and executive officers, nominees for director and any immediate family members of directors, executive officers or nominees for director and greater than 5% holders of Dow common stock. Companies are also required to describe their policies and procedures for the review, approval or ratification of any related person transaction.

Pursuant to Dow’s Code of Business Conduct, and annual review of Director independence, the Company has had procedures in place to monitor related person transactions for several years. Upon the recommendation of the Governance Committee, the Board of Directors adopted a formal written policy on related person transactions on February 15, 2007 (the “Policy”).

The Governance Committee is responsible for reviewing the material facts of all transactions that could potentially be “transactions with related persons.” The Policy covers any transaction, arrangement or relationship or series of similar transactions, arrangements or relationships (including any indebtedness or guarantee of indebtedness) in which:

(1) the aggregate amount involved will or may be expected to exceed $100,000 in any calendar year,

(2) the Company is a participant, and

(3) any related person has or will have a direct or indirect interest (other than solely as a result of being a director or a less than 10% beneficial owner of another entity).

The Governance Committee is responsible to either approve or disapprove of the entry into the transaction, subject to the exceptions listed below. If advance Committee approval of the transaction is not feasible, then the transaction shall be considered and, if the Committee determines it to be appropriate, ratified at the Committee’s next regularly scheduled meeting.

The Governance Committee has determined that certain types of transactions shall be deemed to be preapproved by the Committee even if the amount involved will exceed $100,000, including:

(a) employment of executive officers where the officer’s compensation is either reported in the Proxy Statement or

would have been reported in the Proxy Statement if the officer was a “named executive officer,” and the Compensation and Leadership Development Committee approved such compensation;

(b) Director compensation where such compensation is reported in the Proxy Statement;

(c) certain transactions with other companies where the related person’s only relationship with the other company is as a director, employee or beneficial owner of less than 10% of that company’s shares, and the aggregate amount

involved does not exceed the greater of $1 million or 2% of that company’s total annual revenues;

(d) certain Company charitable contributions where the related person’s only relationship is as an employee or director of the charitable entity and where the aggregate amount does not exceed the greater of $1 million or 2% of the charitable entity’s total annual receipts;

(e) transactions where all stockholders receive proportional benefits;

(f) transactions involving competitive bids; and

(g) regulated transactions.

As discussed above, the Governance Committee has responsibility for reviewing issues involving director independence and related person transactions using information obtained from Directors’ responses to a questionnaire asking about their relationships with the Company, and those of their immediate family members and primary business or charitable affiliations and other potential conflicts of interest, as well as certain data collected by the Company related to transactions, relationships or arrangements between the Company on the one hand and a Director, officer or immediate family member on the other.

As part of its annual independence assessment and review of related person transactions, the Governance Committee reviewed the fact that in 2012 the Company made purchases or sales of products or services in the ordinary course of business with certain entities for which some of our Directors are executive officers or directors. The Governance Committee reviewed such transactions and believes that the related persons’ interests in the transactions are not material.

More specifically and as discussed earlier in this Proxy Statement in the section entitled “Director Independence,” the Governance Committee and the Board reviewed these transactions and the fact that Messrs. Bell, Fettig, Hess and Polman served as executive officers during all or a portion

of the past three years of entities with which Dow made purchases or sales (The Boeing Company, Whirlpool Corporation, Hess Corporation, and Unilever PLC/N.V. respectively). All such purchases and sales were made at arms-length, commercial terms, and the Directors did not personally benefit from such transactions. In all instances, the extent of business represented significantly less than 2% of Dow’s and the other entity’s revenues. In fact, in all cases the amounts were below 0.3%. With respect to Boeing there were no purchases in 2011 or 2012, and with respect to Hess there were no sales in 2012, while with respect to Whirlpool and Unilever there were sales to and purchases from each entity which in all cases were below the 0.3% amount referenced above.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), requires the Company’s Directors and executive officers and persons who own

more than 10% of a registered class of the Company’s equity securities (the “Reporting Persons”) to file with the U.S. Securities and Exchange Commission (“SEC”) reports on Forms 3, 4 and 5 concerning their ownership of and transactions in the common stock and other equity securities of the Company, generally within two business days of a reportable transaction. As a practical matter, the Company seeks to assist its Directors and executives by monitoring transactions and completing and filing reports on their behalf.

Based solely upon a review of SEC filings furnished to the Company and written representations that no other reports were required, we believe that all Reporting Persons complied with these reporting requirements during fiscal year 2012.
