1.   BASIS OF PRESENTATION

     The accompanying unaudited condensed consolidated financial statements have
     been prepared in accordance with accounting principles generally accepted
     in the United States of America for interim financial information
     (Accounting Principles Board Opinion ("APB") No. 28, Interim Financial
     Reporting) and with the instructions to Form 10-Q and Article 10 of
     Regulation S-X. Accordingly, they do not include all of the information
     necessary for a fair presentation of financial position, results of
     operations, and cash flows in conformity with accounting principles
     generally accepted in the United States of America. Operating results for
     interim periods are not necessarily indicative of results that may be
     expected for the fiscal year as a whole. In the opinion of management, the
     condensed consolidated financial statements reflect all adjustments
     (consisting of normal recurring adjustments) considered necessary for a
     fair presentation of the results of Greatbatch, Inc. and its indirect
     wholly-owned subsidiary Greatbatch, Ltd. (collectively the "Company") for
     the periods presented. The preparation of financial statements in
     conformity with accounting principles generally accepted in the United
     States of America requires management to make estimates and assumptions
     that affect the reported amounts of assets, liabilities, sales, expenses,
     and related disclosures at the date of the financial statements and during
     the reporting period. Actual results could differ from these estimates. The
     December 29, 2006 condensed consolidated balance sheet data was derived
     from audited financial statements but does not include all disclosures
     required by accounting principles generally accepted in the United States
     of America. For further information, refer to the consolidated financial
     statements and notes included in the Company's Annual Report on Form 10-K
     for the year ended December 29, 2006. The Company utilizes a fifty-two,
     fifty-three week fiscal year ending on the Friday nearest December 31st.
     For 52-week years, each quarter contains 13 weeks. The first quarter of
     2007 and 2006 ended on March 30 and March 31, respectively.

     Convertible Subordinated Notes - In May 2003, the Company completed a
     private placement of $170.0 million of 2.25% convertible subordinated
     notes, due 2013 ("CSN I"). In November 2003 the Company had a registration
     statement with the Securities and Exchange Commission ("SEC") declared
     effective with respect to these notes and the underlying common stock. In
     March 2007, the Company entered into separate, privately negotiated
     agreements to exchange $117.8 million of CSN I for an equivalent principal
     amount of a new series of 2.25% convertible subordinated notes due 2013
     ("CSN II") (collectively the "Exchange").

     The primary purpose of the Exchange was to eliminate the June 15, 2010 call
     and put option that is included in the terms of CSN I. In connection with
     the Exchange, the Company issued an additional $80 million aggregate
     principal amount of CSN II at a price of $950 per $1,000 of principal. In
     April 2007, the Company filed a registration statement with the SEC with
     respect to these notes and has 90 days from March 28, 2007 to have such
     registration statement declared effective. In the event that the Company
     fails to comply with this requirement it is obligated to make additional
     payments equal to 0.5% of the aggregate principal amount outstanding.

     The Exchange was accounted for as an extinguishment of debt and resulted in
     a pre-tax gain of $4.5 million ($2.9 million net of tax) or $0.11 per
     diluted share. As a result of the extinguishment, the Company had to
     recapture the tax interest expense that was previously deducted on the
     extinguished debentures. This resulted in an additional current income tax
     liability of approximately $11.3 million, which is payable in 2007. This
     amount was previously recorded as a non-current deferred tax liability on
     the balance sheet. The following is a summary of the significant terms of
     CSN I and CSN II:

     CSN I - The notes bear interest at 2.25 percent per annum, payable
     semiannually. Holders may convert the notes into shares of the Company's
     common stock at a conversion rate of 24.8219 shares per $1,000 of
     principal, subject to adjustment, before the close of business on June 15,
     2013 only under the following circumstances: (1) during any fiscal quarter
     commencing after July 4, 2003, if the closing sale price of the Company's
     common stock exceeds 120% of the $40.29 conversion price for at least 20
     trading days in the 30 consecutive trading day period ending on the last
     trading day of the preceding fiscal quarter; (2) subject to certain
     exceptions, during the five business days after any five consecutive
     trading day period in which the trading price per $1,000 of principal for
     each day of such period was less than 98% of the product of the closing
     sale price of the Company's common stock and the number of shares issuable
     upon conversion of $1,000 of principal; (3) if the notes have been called
     for redemption; or (4) upon the occurrence of certain corporate events.

     Beginning June 20, 2010, the Company may redeem any of the notes at a
     redemption price of 100% of their principal amount, plus accrued interest.
     Note holders may require the Company to repurchase their notes on June 15,
     2010 or at any time prior to their maturity following a fundamental change
     at a repurchase price of 100% of their principal amount, plus accrued
     interest. The notes are subordinated in right of payment to all of our
     senior indebtedness and effectively subordinated to all debts and other
     liabilities of the Company's subsidiaries.

     Beginning with the six-month interest period commencing June 15, 2010, the
     Company will pay additional contingent interest during any six-month
     interest period if the trading price of the notes for each of the five
     trading days immediately preceding the first day of the interest period
     equals or exceeds 120% of the principal amount of the notes.

     CSN II - The notes bear interest at 2.25 percent per annum, payable
     semiannually. The holders may convert the notes into shares of the
     Company's common stock at a conversion price of $34.70 per share, which is
     equivalent to a conversion ratio of 28.8219 shares per $1,000 of principal.
     The conversion price and the conversion ratio will adjust automatically
     upon certain changes to the Company's capitalization.

     The notes are convertible at the option of the holders at such time as: (i)
     the closing price of the Company's common stock exceeds 150% of the
     conversion price of the notes for 20 out of 30 consecutive trading days;
     (ii) the trading price per $1,000 of principal is less than 98% of the
     product of the closing sale price of common stock for each day during any
     five consecutive trading day period and the conversion rate per $1,000 of
     principal; (iii) the notes have been called for redemption; (iv) the
     Company distributes to all holders of common stock rights or warrants
     entitling them to purchase additional shares of common stock at less than

    NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (con't) - Unaudited

     the average closing price of common stock for the ten trading days
     immediately preceding the announcement of the distribution; (v) the Company
     distributes to all holders of common stock any form of dividend which has a
     per share value exceeding 5% of the price of the common stock on the day
     prior to such date of distribution; (vi) the Company affects a
     consolidation, merger, share exchange or sale of assets pursuant to which
     its common stock is converted to cash or other property; (vii) the period
     beginning 60 days prior to but excluding June 15, 2013; and (viii) certain
     fundamental changes occur or are approved by the Company's Board of
     Directors.

     Conversions in connection with corporate transactions that constitute a
     fundamental change require the Company to pay a premium make-whole amount
     whereby the conversion ratio on the notes may be increased by up to 8.2
     shares per $1,000 of principal. The premium make-whole amount will be paid
     in shares of common stock upon any such conversion, subject to the net
     share settlement feature of the notes described below.

     The notes contain a net share settlement feature that requires the Company
     to pay cash for each $1,000 of principal. Any amounts in excess of $1,000
     will be settled in shares of the Company's common stock, or at the
     Company's option, cash. The Company has a one-time irrevocable election to
     pay the holders in shares of its common stock, which it currently does not
     plan to exercise.

     The notes are redeemable by the Company at any time on or after June 20,
     2012, or at the option of a holder upon the occurrence of certain
     fundamental changes affecting the Company. The notes are subordinated in
     right of payment to all of our senior indebtedness and effectively
     subordinated to all debts and other liabilities of the Company's
     subsidiaries.

     The following is a reconciliation of deferred financing fees for the first
     quarter of 2007, which are included in other assets:

     Balance at December 29, 2006                           $    2,305
     Financing costs deferred                                    4,331
     Write off during the period due to extinguishment          (1,416)
     Amortization during the period                               (180)
                                                            -----------
     Balance at March 30, 2007                              $    5,040
                                                            ===========


     The $4.3 million of financing fees deferred in connection with the Exchange
     and new CSN II notes issued will be paid in the second quarter of 2007.

     Revolving Line of Credit - The Company maintains a three-year $50 million
     Revolving Credit Facility (the "Revolver"), which contains a $10.0 million
     sub-limit for the issuance of commercial or standby letters of credit. The
     Revolver is secured by the Company's non-realty assets including cash,
     accounts and notes receivable, and inventories and has an expiration date
     of May 31, 2008. The Revolver requires compliance with two quarterly
     financial covenants, as defined. The first relates to the ratio of
     consolidated net earnings or loss before interest, taxes, depreciation, and
     amortization ("EBITDA") to fixed charges. The second is a leverage ratio,
     which is calculated based on the ratio of consolidated funded debt less
     cash, cash equivalent investments and short-term investments to
     consolidated EBITDA. Interest rates under the Revolver vary with the

     Company's leverage. The Company is required to pay a commitment fee of
     between 0.125% and 0.250% per annum on the unused portion of the Revolver
     based on the Company's leverage. As of March 30, 2007, the Company had no
     balance outstanding on the Revolver.

     In April 2007, the Company signed a commitment letter for a new five-year
     senior credit facility (the "Credit Facility") consisting of a $235 million
     revolving credit facility, which can be increased to $335 million upon the
     Company's request. The Credit Facility also contains a $15 million letter
     of credit subfacility and a $15 million swingline subfacility. This Credit
     Facility will replace the $50 million Revolver and has similar financial
     covenants, interest rates, commitment fees and prioritization as the
     Revolver. The Company expects that this agreement will become effective in
     the second quarter of 2007.

7.   STOCK-BASED COMPENSATION

     Compensation costs related to share-based payments for the three months
     ended March 30, 2007 totaled $1.7 million, $1.1 million net of tax, or
     $0.04 per diluted share. This compares to $1.4 million, $0.9 million net of
     tax, or $0.03 per diluted share for the three months ended March 31, 2006.

--------------------------------------------------------------------------------

     (a) Alden Facility consolidation - Beginning in the first quarter of 2005
     and ending in the second quarter of 2006 the Company consolidated the
     medical capacitor manufacturing operations in Cheektowaga, NY, and the
     implantable medical battery manufacturing operations in Clarence, NY, into
     the advanced power source manufacturing facility in Alden, NY ("Alden
     Facility"). The Company also consolidated the capacitor research,
     development and engineering operations from the Cheektowaga, NY facility
     into the Technology Center in Clarence, NY.

     The total cost for these consolidation efforts was $3.4 million, which was
     below the Company's original estimate of $3.5 to $4.0 million. The expenses
     for the Alden Facility consolidation are included in the IMC business
     segment and included the following:

     o    Production inefficiencies and revalidation - $0.3 million;
     o    Moving and facility closures - $2.7 million; and
     o    Other - $0.4 million.

     (b) Carson City Facility shutdown and Tijuana Facility consolidation No. 1.
     On March 7, 2005, the Company announced its intent to close the Carson
     City, NV facility ("Carson City Facility") and consolidate the work
     performed at that facility into the Tijuana, Mexico facility ("Tijuana
     Facility consolidation No. 1").

     The Company delayed the anticipated final closing of the Carson City
     Facility until the second quarter of 2007 in order to accommodate a
     customer's regulatory approval. If this closing is delayed further,
     additional costs could be incurred. The total revised estimate for this
     plan is anticipated to be between $7.7 million and $7.9 million of which
     $7.6 million has been incurred through March 30, 2007. The major categories
     of costs include the following:

     o    Costs related to the shutdown of the Carson City Facility:
          a.   Severance and retention - $3.9 million;
          b.   Accelerated depreciation - $0.6 million; and
          c.   Other - $0.5 million.

     o    Costs related to the Tijuana Facility consolidation No. 1:
          a.   Production inefficiencies and revalidation - $0.4 million;
          b.   Relocation and moving - $0.2 million;
          c.   Personnel (including travel, training and duplicate wages) - $1.5
               to $1.7 million; and
          d.   Other - $0.6 million.

     All categories of costs are considered to be cash expenditures, except
     accelerated depreciation. Once the moves are completed, the Company
     anticipates annual cost savings in the range of $2.5 million to $3.1
     million. The expenses for the Carson City Facility shutdown and the Tijuana
     Facility consolidation No. 1 are included in the IMC business segment.

     (c) Columbia Facility shutdown, Tijuana Facility consolidation No. 2 and
     RD&E consolidation. On November 16, 2005, the Company announced its intent
     to close both the Columbia, MD facility ("Columbia Facility") and the
     Fremont, CA Advanced Research Laboratory ("ARL"). The manufacturing
     operations at the Columbia Facility will be moved into the Tijuana Facility
     ("Tijuana Facility consolidation No. 2"). The research, development and
     engineering ("RD&E") and product development functions at the Columbia
     Facility and at ARL will relocate to the Technology Center in Clarence, NY.

     The total estimated cost for this facility consolidation plan is
     anticipated to be between $8.4 million and $8.9 million of which $7.6
     million has been incurred through March 30, 2007. The ARL move and closure
     portion of this consolidation project is complete. The Company expects to
     incur and pay the remaining cost for the other portions of the
     consolidation project in 2007.

     (d) Electrochem Commercial Power ("ECP") expansion. In February 2007, the
     Company announced that it will close its current manufacturing facility in
     Canton, MA and construct a new 80,000 square foot facility in the
     Massachusetts area to perform those operations in. The expected completion
     of this $28 million expansion project is mid-2008. The total expense to be
     recognized for this relocation is estimated to be $2.2 million to $2.4
     million. Costs related to this move are included in the ECP business
     segment and include the following:

     o    Production inefficiencies and revalidation - $0.6 million;
     o    Moving and facility closure - $0.9 million to $1.0 million;
     o    Accelerated depreciation - $0.4 million; and
     o    Other - $0.3 million to $0.4 million.

     (e) Asset dispositions and other. During the first quarter of 2007, the
     Company received $0.3 million of insurance proceeds related to equipment
     damaged during transportation to the Tijuana Facility in the second quarter
     of 2006. The remaining expense is for property, plant and equipment
     dispositions.

9.   INCOME TAXES

     Effective in the first quarter of 2007, the Company adopted the provisions
     of Financial Standards Accounting Board ("FASB") Interpretation ("FIN") No.
     48 Accounting for Uncertainty in Income Taxes, an interpretation of FASB
     Statement of Financial Accounting Standards ("SFAS") No. 109. FIN No. 48
     clarifies the accounting for uncertainty in income taxes recognized under
     SFAS 109. FIN No. 48 prescribes a recognition threshold and measurement
     attribute for financial statement recognition and measurement of a tax
     position taken or expected to be taken in a tax return and also provides
     guidance on various related matters such as derecognition, interest and
     penalties, and disclosure.

     Upon adoption of FIN No. 48, the Company did not recognize any adjustment
     to its $1.8 million of unrecognized tax benefits, all of which would
     favorably impact the effective tax rate (net of federal benefit on state
     issues), if recognized. The Company's unrecognized tax benefits consist of
     refund claims which did not meet the more likely than not threshold under
     FIN No. 48. At the end of the first quarter, there was no change in the
     balance of unrecognized tax benefits. The Company anticipates that the
     total unrecognized tax benefits could significantly change within the next
     twelve months due to the settlement of audits/appeals currently in process,
     however, quantification of an estimated range cannot be made at this time.

     The Company will recognize interest expense related to uncertain tax
     positions as Interest Expense. Penalties, if incurred, would be recognized
     as a component of Selling, General and Administrative Expenses. At the end
     of the first quarter, there was no accrued interest or penalties related to
     uncertain tax positions. The tax years 2003-2006 remain open to examination
     by the major taxing jurisdictions to which we are subject. The 2001 and
     2002 tax years remain open in certain jurisdictions as a result of
     audits/appeals currently in process.

10.  COMMITMENTS AND CONTINGENCIES

     Litigation - The Company is a party to various legal actions arising in the
     normal course of business including actions brought by former employees who
     were terminated in connection with our consolidation initiatives. While the
     Company does not believe that the ultimate resolution of any such pending
     activities will have a material adverse effect on its consolidated results
     of operations, financial position or cash flows, litigation is subject to
     inherent uncertainties. If an unfavorable ruling were to occur, there
     exists the possibility of a material adverse impact in the period in which
     the ruling occurs.

     During 2002, a former non-medical customer commenced an action alleging
     that the Company had used proprietary information of the customer to
     develop certain products. We have meritorious defenses and are vigorously
     defending the matter. The potential risk of loss is between $0.0 and $1.7
     million.

     Product Warranties - The Company generally warrants that its products will
     meet customer specifications and will be free from defects in materials and
     workmanship. The Company accrues its estimated exposure to warranty claims
     based upon recent historical experience and other specific information as
     it becomes available.

     The change in aggregate product warranty liability for the quarter ended
     March 30, 2007 is as follows (in thousands):

     Beginning balance at December 29, 2006      $    1,993
     Additions to warranty reserve                      452
     Warranty claims paid                              (721)
                                                ------------
     Ending balance at March 30, 2007            $    1,724
                                                ============

     Purchase Commitments - Contractual obligations for purchase of goods or
     services are defined as agreements that are enforceable and legally binding
     on the Company and that specify all significant terms, including: fixed or
     minimum quantities to be purchased; fixed, minimum or variable price
     provisions; and the approximate timing of the transaction. Our purchase
     orders are normally based on our current manufacturing needs and are
     fulfilled by our vendors within short time horizons. We enter into blanket
     orders with vendors that have preferred pricing and terms, however these
     orders are normally cancelable by us without penalty. As of March 30, 2007,
     the total contractual obligation related to such expenditures is
     approximately $10.5 million and will be financed by existing cash,
     short-term investments or cash generated from operations. We also enter
     into contracts for outsourced services; however, the obligations under
     these contracts were not significant and the contracts generally contain
     clauses allowing for cancellation without significant penalty.

13.  BUSINESS SEGMENT INFORMATION

     The Company operates its business in two reportable segments: Implantable
     Medical Components ("IMC") and Electrochem Commercial Power ("ECP"). The
     IMC segment designs and manufactures critical components used in
     implantable medical devices. The principal components are batteries,
     capacitors, filtered feedthroughs, enclosures and precision components.
     Additionally, the IMC business includes value-added assembly of products
     that incorporate these components. The principal medical devices are
     pacemakers, defibrillators and neurostimulators. The ECP segment designs
     and manufactures high performance batteries and battery packs; principal
     markets for these products are for oil and gas exploration, pipeline
     inspection, telematics, oceanography equipment, seismic, communication,
     military and aerospace applications.

     The Company defines segment income from operations as sales less cost of
     sales, including amortization, and expenses attributable to
     segment-specific selling, general, administrative, research, development,
     engineering and other operating expenses. Segment income also includes a
     portion of non-segment specific selling, general, administrative, research,
     development and engineering expenses based on allocations appropriate to
     the expense categories. The remaining unallocated operating expenses are
     primarily corporate headquarters and administrative function expenses. The
     unallocated operating expenses along with other income and expense are not
     allocated to reportable segments. Transactions between the two segments are
     not significant.

     An analysis and reconciliation of the Company's business segment
     information to the respective information in the consolidated financial
     statements is as follows (in thousands):

14.  ACQUISITIONS (Subsequent Event)

     On April 3, 2007, the Company acquired substantially all of the assets of
     BIOMEC, Inc. ("BIOMEC") for $11.4 million in cash and future additional
     consideration. BIOMEC has grants in place that will fund substantially all
     of its development costs through 2008. Currently, the engineering team is
     working on various projects, including a novel-polymer coating (biomimetic)
     that mimics the surface of endothelial cells of blood vessels.
     Additionally, BIOMEC has a product development agreement and a 20%
     investment partnership in IntElect Medical, Inc., an early stage
     neurostimulation device company that works in conjunction with the
     Cleveland Clinic. This transaction was accounted for under the purchase
     method of accounting.

     On April 30, 2007, the Company jointly announced with Enpath Medical, Inc.
     ("Enpath") that they have entered into a definitive merger agreement under
     which the Company will acquire Enpath for $14.38 per share in cash, or
     approximately $102 million, including assumption of debt. Under the terms
     of the agreement, the Company will commence a tender offer for all of
     Enpath's outstanding shares no later than May 8, 2007. The transaction is
     subject to customary closing conditions and regulatory approvals and the
     tender of a majority of Enpath's outstanding shares, on a fully diluted
     basis. The purchase price will be funded out of the Company's available
     cash and short-term investments. The transaction is expected to close in
     late June. Enpath is a medical products company engaged in designing,
     developing, manufacturing and marketing single use medical device products
     for the cardiac rhythm management, neuromodulation and interventional
     radiology markets.

15.  IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

     In February 2007, the FASB issued SFAS No 159, The Fair Value Option for
     Financial Assets and Financial Liabilities--Including an amendment of FASB
     Statement No. 115. This Statement provides entities with an option to
     choose to measure eligible items at fair value at specified election dates.
     If elected, an entity must report unrealized gains and losses on the item
     in earnings at each subsequent reporting date. The fair value option: may
     be applied instrument by instrument, with a few exceptions, such as
     investments otherwise accounted for by the equity method; is irrevocable
     (unless a new election date occurs); and is applied only to entire
     instruments and not to portions of instruments. The Company is still
     evaluating the impact of SFAS No. 159 on its financial statements, which is
     effective beginning in fiscal year 2008.

     In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements.
     This Statement defines fair value, establishes a framework for measuring
     fair value while applying generally accepted accounting principles, and
     expands disclosures about fair value measurements. SFAS No. 157 establishes
     a fair value hierarchy that distinguishes between (1) market participant
     assumptions based on market data obtained from independent sources and (2)
     the reporting entity's own assumptions developed based on unobservable
     inputs. The Company is still evaluating the impact of SFAS No. 157 on its
     financial statements, which is effective beginning in fiscal year 2008.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
--------------------------------------------------------------------------------

Our Business

We are a leading developer and manufacturer of batteries, capacitors,
feedthroughs, enclosures, and other components used in implantable medical
devices ("IMDs") through our Implantable Medical Components ("IMC") business. We
offer technologically advanced, highly reliable and long lasting products that
enable our customers to introduce IMDs that are progressively smaller, longer
lasting, more efficient and more functional. Additionally, through our
manufacturing facility in Tijuana Mexico, our IMC business includes value-added
assembly of products that incorporates the components we manufacture. We also
leverage our core competencies in technology and manufacturing through our
Electrochem Commercial Power ("ECP") business to develop and produce cells and
battery packs for commercial applications that demand high performance and
reliability, including oil and gas exploration, pipeline inspection, telematics,
oceanographic equipment, seismic, communication, military and aerospace
applications. Most of the IMC products that we sell are utilized by customers in
cardiac rhythm management ("CRM") devices. The CRM market comprises devices
utilizing high-rate batteries and capacitors such as implantable cardioverter
defibrillators ("ICDs") and cardiac resynchronization therapy ("CRT") with
backup defibrillation devices ("CRT-D") and devices utilizing low or medium rate
batteries but no capacitors (pacemakers and CRTs). All CRM devices utilize other
components such as enclosures and feedthroughs, and certain CRM devices utilize
electromagnetic interference ("EMI") filtering technology.

Our Customers

Our products are designed to provide reliable, long lasting solutions that meet
the evolving requirements and needs of our customers and the end users of their
products. Our medical customers include leading IMD manufacturers such as Boston
Scientific, St. Jude Medical, Medtronic, Biotronik, Cyberonics and the Sorin
Group. A substantial part of our business is conducted with a limited number of
customers. For the first quarter of 2007, Boston Scientific, Medtronic and St.
Jude Medical collectively accounted for approximately 69% of our total sales
compared to 70% for the first quarter of 2006. The nature and extent of our
selling relationships with each CRM customer are different in terms of breadth
of component products purchased, purchased product volumes, length of
contractual commitment, ordering patterns, inventory management and selling
prices. Our ECP customers are primarily companies involved in oil and gas
exploration, pipeline inspection, telematics, oceanographic equipment, seismic,
communication, military and aerospace applications industries. We have entered
into long-term supply agreements with some of our customers. For each of our
products, we recognize revenue when the products are shipped and title passes.

Business Highlights

     o    Total Company - record sales of $76.9 million, an increase of 13%
          compared to $68.1 million in 2006.
          >>   IMC - record sales of $65.2 million, an increase of 13% compared
               to $57.6 million in 2006, driven by growth of ICD capacitors,
               feedthroughs and assembly products partially offset by a decrease

Our CEO's View

We had a solid start to the year achieving sales of $76.9 million, a 13%
increase over last years first quarter. Medical sales were at $65.2 million and
the Commercial business achieved growth of 11%. We earned 43 cents in the
quarter compared with 28 cents last year. This result is inclusive of a one-time
gain of 11 cents from the exchange of $117.8 million of our subordinated
convertible debentures.

Our ICD capacitor sales more than doubled in the quarter to $8.5 million, a $4.9
million increase over the prior year first quarter. Our lean manufacturing
systems enabled reduced lead times to capture this revenue opportunity.
Approximately half of the increase in the quarter was due to inventory
replenishment by our customers. In addition to inventory related demand, sales
increased as a result of a customer supply issue. We anticipate this higher
level of demand continuing into the second quarter.

We also continue to experience growth in our feedthrough business with sales
increasing by 13% over last years first quarter. The majority of this growth has
come from domestic market share penetration.

Other medical products sales increased by $2.2 million, or 17% from last year.
Other medical sales consists of assembly, coatings and machined components. The
growth in this quarter was split evenly between the coatings and assembly
products.

ICD battery sales declined by 8% and pacemaker and other battery volume
increased slightly from the first quarter of last year. However, on a sequential
basis, ICD sales were up 16% from the fourth quarter of 2006. The first quarter
2006 represented our toughest year-over-year comparison. ICD battery sales
softened through the balance of 2006 reflecting the general slowdown in the ICD
market.

On the commercial side of the business, sales were up 11% from last years first
quarter. The growth in the quarter primarily came from oil & gas, pipeline
inspection and military markets. Oil and gas drilling activity remains strong
and continues to drive the core growth of the business. The growth over the last
two years has resulted in launching our capacity expansion plan. We are in the
process of developing facility plans which will more than double our existing
capacity. We plan to begin construction of a new 80,000 square foot
manufacturing facility in the Massachusetts area in June of this year. We expect
to complete this important expansion project by mid- 2008. In addition to a new
expanded facility, we will also be investing in semi-automation equipment.

We have recently completed several important transactions. First, we refinanced
$117.8 million of our existing convertible debentures and issued $80 million in
new debentures. Second, on April 3rd we completed the acquisition of BIOMEC
which expands our offerings to include design service capabilities, and third,
we received customer clearance to complete the closure of our Carson City
facility, which is now scheduled for June 2007. Additionally, on April 30, 2007

                                      -22-

we announced that we signed a definitive agreement to acquire Enpath Medical, a
developer, manufacturer and marketer of single use medical device products for
the cardiac rhythm management, neuromodulation and interventional radiology
markets. We view the acquisition of Enpath as another long-term growth platform
and is consistent with our stated goal of broadening both our market and product
reach.

Product Development

Currently, the company is developing a series of new products for customer
applications in the CRM, neurostimulation and commercial markets.

Some of the key development initiatives are as follows:

     1.   Continue the evolution of our Q series high rate ICD batteries.
     2.   Complete the development of a high voltage and high energy density
          capacitor system.
     3.   Develop Q series medium rate battery for neurostimulation and
          pacemaker applications.
     4.   Augment our existing rechargeable battery with a new rechargeable
          battery offering for use in neurostimulation applications.
     5.   Develop rechargeable battery packs for use in commercial applications.
     6.   Continue development of the batteries and capacitors used in
          intravascular ICD devices.

IMC. Our near term focus for growth in the medical battery market, a portion of
our IMC business, is the introduction of our Q-Series batteries. Initially they
will be available in two configurations - QHR (High Rate) and QMR (Medium Rate).
These batteries hold the promise of unparalleled performance in a wide range of
implantable device and neurostimulation applications and allow our customers to
incorporate advanced power-hungry features into these devices. It delivers
advanced performance criteria to an industry that historically embraces new
products. We believe the Q-Series will represent a major breakthrough by
combining a smaller size with greater energy density (more power). The first ICD
device implant with our new QHR technology occurred in the third quarter of
2006. We expect a second customer to begin implanting our QHR technology in the
near term. We also released a new, non-proprietary model of medium-rate
implantable "Q" series battery.

In addition to primary batteries, our rechargeable battery program also
continues to make progress in qualification and is receiving tremendous interest
from Neurostimulation customers.

In addition to our battery programs, we continue to advance our ICD capacitor
technology with the development of a higher energy capacitor expected for
release in 2008. Furthermore, we continue to develop the technology for a next
generation higher voltage capacitor.

Finally, enabling safe MRI device interaction continues to remain a key focus
and represents a potential growth opportunity for the company. We anticipate
unveiling a series of new technologies in this area in the near future.

ECP. ECP continues to develop new and innovative power solutions for the world's
most demanding commercial applications. ECP has developed a new high energy
lithium cell for a customer in the telematics market. Due to their exceptional
high energy, two of these new cells are capable of providing power for the
entire 10-year life of the telematics device. ECP also has developed a battery
pack capable of withstanding the customer's harsh operating conditions such as
high vibration, high shock, salt spray, high temperature, low temperature, and
high humidity.

                                      -23-


Finally, ECP has developed a modular battery pack for a customer's fleet of
underwater sonabuoys which measure water characteristics. The long life of ECP
cells, coupled with their ability to withstand harsh conditions, make them
ideally suited for buoys. The customer's expense of commissioning a ship to
replace the batteries in each buoy is reduced when using ECP batteries due to
their long life.

Cost Savings and Consolidation Efforts

During 2005, we initiated several significant cost savings and consolidation
efforts, the implementation of which continued during 2006 and the first three
months of 2007.

Alden Facility Consolidation. Beginning in the first quarter of 2005 and ending
in the second quarter of 2006 we consolidated our medical capacitor
manufacturing operations in Cheektowaga, NY, and our implantable medical battery
manufacturing operations in Clarence, NY, into our advanced power source
manufacturing facility in Alden, NY ("Alden Facility"). We also consolidated our
capacitor research, development and engineering operations from our Cheektowaga,
NY facility into our Technology Center in Clarence, NY.

The total cost for these consolidation efforts was $3.4 million, which was below
the Company's original estimate of $3.5 to $4.0 million. Expenses of $2.8
million were incurred in 2005 and $0.6 million were incurred during the first
two quarters of 2006. In total, $1.8 million was paid in cash and $0.8 million
was for assets written-off in 2005. Approximately $0.8 million was paid in cash
during 2006. The expenses for the Alden Facility consolidation were included in
the IMC business segment.

Carson City Facility shutdown and Tijuana Facility consolidation No. 1. On March
7, 2005, we announced our intent to close the Carson City, NV facility ("Carson
City Facility") and consolidate the work performed at our Carson City Facility
into our Tijuana, Mexico facility ("Tijuana Facility consolidation No. 1").

The Company delayed the anticipated final closing of the Carson City Facility
until the second quarter of 2007 in order to accommodate a customer's regulatory
approval. If this closing is delayed further, additional costs could be
incurred. The total revised estimate for this plan is anticipated to be between
$7.7 million and $7.9 million of which $7.6 million has been incurred and is
comprised of $5.0 million for the Carson City Facility shutdown and $2.7 million
to $2.9 million for the Tijuana Facility consolidation No. 1. To date, $7.6
million of expenses has been recorded. All categories of costs are considered to
be cash expenditures, except for accelerated depreciation.

Carson City Facility shutdown expenses of $4.7 million have been incurred to
date, of which $4.4 million were recorded in 2005 and 2006, and $0.3 million
were incurred in the first three months of 2007. In 2005 and 2006, $2.6 million
were paid in cash and $0.6 million were recorded as accelerated depreciation. In
2007, $0.1 million were paid in cash. To date, $2.5 million of the $3.8 million
of severance and retention recorded to date was paid. Tijuana Facility
consolidation No. 1 expenses of $2.8 million were incurred and paid in 2005 and
2006, and $0.1 million were incurred and paid in 2007.

Once the moves are completed, we anticipate annual cost savings in the range of
$2.5 to $3.1 million. The expenses for the Carson City Facility shutdown and the
Tijuana Facility consolidation No. 1 are included in the IMC business segment.

                                      -24-


Columbia Facility & ARL shutdown, Tijuana Facility consolidation No. 2, and RD&E
Consolidation. On November 16, 2005, we announced our intent to close both our
Columbia, MD facility ("Columbia Facility") and our Fremont, CA Advanced
Research Laboratory ("ARL"). The manufacturing operations at our Columbia
Facility will be moved into our Tijuana Facility ("Tijuana Facility
consolidation No. 2"). The research, development and engineering ("RD&E") and
product development functions at our Columbia Facility have begun to relocate to
the Technology Center in Clarence, NY. The ARL relocation to the Technology
Center in Clarence, NY is complete.

The total revised estimated cost for this facility consolidation plan is
anticipated to be between $8.4 million and $8.9 million. To date, we have
expensed $7.6 million related to these projects and expect to incur the
remaining costs in 2007. All categories of costs are considered to be future
cash expenditures, except for accelerated depreciation and asset write-offs.

Approximately $3.9 million of the Columbia Facility and ARL shutdown costs were
incurred in 2005 and 2006 ($0.5 million for assets written-off), and $0.6
million were incurred in the first three months of 2007. Approximately $0.3
million was paid in cash during the first three months of 2007. Tijuana Facility
consolidation plan No. 2 expenses of $2.3 million were incurred and paid in cash
in 2006 and $0.7 million in the first quarter of 2007.

Once the moves are completed, the Company anticipates annual cost savings in the
range of $5.0 to $6.0 million. The expenses for the Columbia Facility and ARL
shutdowns, the Tijuana Facility consolidation No. 2 and the RD&E consolidation
are included in the IMC business segment.

ECP Expansion. In February 2007, the Company announced that it will close its
current manufacturing facility in Canton, MA and construct a new 80,000 square
foot facility in the Massachusetts area to perform those operations in. The
expected completion of this $28 million expansion project is mid-2008. The total
expense to be recognized for this relocation is estimated to be $2.2 million to
$2.4 million. During the first three months of 2007, approximately $0.1 million
of costs were incurred related to this project, which were primarily non-cash
items. Costs related to this move are included in the ECP business segment.

Sales

IMC. The nature and extent of our selling relationship with each CRM customer is
different in terms of component products purchased, selling prices, product
volumes, ordering patterns and inventory management. We have pricing
arrangements with our customers that at times do not specify minimum order
quantities. Our visibility to customer ordering patterns is over a relatively
short period of time. Our customers may have inventory management programs and
alternate supply arrangements of which we are unaware. Additionally, the
relative market share among the CRM device manufacturers changes periodically.
Consequently, these and other factors can significantly impact our sales in any
given period.

                                      -26-


Our customers may initiate field actions with respect to market-released
products. These actions may include product recalls or communications with a
significant number of physicians about a product or labeling issue. The scope of
such actions can range from very minor issues affecting a small number of units
to more significant actions. There are a number of factors, both short-term and
long-term related to these field actions that may impact our results. In the
short-term, if product has to be replaced, or customer inventory levels have to
be restored, this will result in increased component demand. Also, changing
customer order patterns due to market share shifts or accelerated device
replacements may also have a positive impact on our sales results in the
near-term. These same factors may have longer-term implications as well.
Customer inventory levels may ultimately have to be rebalanced to match demand.

The increase in IMC sales of 13% for the three month period ending March 30,
2007 was driven by growth of ICD capacitors, feedthroughs and coatings and
assembly products, which are included in the other medical category. Our ICD
capacitor sales more than doubled in the quarter, to $8.5 million, a $4.9
million increase over the prior year. Approximately half of the increase was due
to our customers replenishing inventory in the current quarter. In addition to
inventory related demand, sales increased as a result of a customer supply
issue, which we anticipate continuing into the second quarter. We also continued
to experience growth in our feedthrough business with sales increasing by 13%
from last year. The majority of this growth has come from domestic market share
penetration.

This growth was partially offset by lower sales from ICD batteries as well as
medical enclosures. ICD battery sales declined by 8%. However, ICD sales were up
16% from fourth quarter of 2006. ICD battery sales softened through the balance
of 2006 reflecting the general slowdown in the ICD market but began to rebound
in the first quarter of 2007.

ECP. Similar to IMC customers, we have pricing arrangements with our customers
that many times do not specify minimum quantities. Our visibility to customer
ordering patterns is over a relatively short period of time.

ECP sales increased 11% from last year. The growth in the quarter primarily came
from oil & gas, pipeline inspection and military markets. Oil and gas drilling
activity remains strong and continues to drive the core growth of the business.

Cost of Sales

Changes from the prior year to cost of sales as a percentage of sales were
primarily due to the following:

                                                             ===================

(a)  This increase in cost of sales is primarily due to lower production of ICD
     batteries, which absorb a greater amount of fixed costs such as plant
     overhead and depreciation. In the prior year period, ICD production volume
     was 9% higher in response to increased sales and replenishment of safety
     stock.

                                      -27-

(b)  The Tijuana Facility was fully operational in the first quarter of 2006 but
     was not being fully utilized as it was only producing sub-assemblies. In
     2007, the facility was producing increased volumes of sub-assemblies and
     the majority of the filtered feedthroughs reducing the excess capacity from
     the prior year. In accordance with the Company's inventory accounting
     policy, excess capacity costs were expensed.
(c)  The revenue increase from 2006 was primarily in capacitors, which generally
     have lower margins.

We expect cost of sales as a percentage of sales to decrease over the next
several years as the result of the consolidation efforts and the elimination of
excess capacity. Excess capacity for the Tijuana Facility is not expected to be
eliminated until mid-2007 when the last announced consolidation effort is
anticipated to be completed (see the "cost savings and consolidation efforts"
section for additional information).

SG&A expenses

Changes from the prior year to SG&A expenses were due to the following (in

(a)  Increase in stock-based compensation related to our leadership succession
     planning transition. The increase in stock-based compensation expense is
     expected to continue into the future.
(b)  The increased workforce expense was a result of the Company's efforts to
     increase the marketing and sales of its products as well as general and
     administrative costs related to finance personnel additions in 2006.
(c)  Increase in director fees is consistent with the approved plan as disclosed
     in our most recent proxy. (d) Increase in legal fees is due to customer
     contract negotiations and the financing transactions discussed above.

                                             ===============================

The increase in RD&E expenses for the three month period ended March 30, 2007 is
primarily due to the planned increase in engineering personnel costs
(headcount), as we continue to invest substantial resources to develop new
products. In terms of the development costs billed, reimbursements were lower
due to lower volume and timing of reimbursable development projects.
Reimbursements for achieving certain development milestones are netted against
gross spending.

(a)  Refer to the "Cost Savings and Consolidation Efforts" discussion for
     disclosure related to the timing and level of remaining expenditures for
     these items as of March 30, 2007.
(b)  During the first quarter of 2007, the Company received $0.3 million of
     insurance proceeds related to equipment damaged during transportation to
     the Tijuana Facility in the second quarter of 2006. The remaining expense
     is for property, plant and equipment dispositions.

Interest expense and interest income

Interest expense for the three months ended March 30, 2007 is consistent with
prior year periods, and is primarily related to our outstanding convertible
notes. Interest expense is expected to increase in the future as a result of the
additional $80.0 million of 2.25% convertible subordinated notes issued during
the first quarter of 2007 and additional amortization of deferred fees and
discounts associated with these notes and the notes exchanged during the quarter
(See Gain on extinguishment of debt).

Interest income for the three months ended March 30, 2007 increased in
comparison to the same periods of 2006 primarily due to increased cash, cash
equivalents and short-term investment balances.

Gain on extinguishment of debt

In March 2007, the Company entered into separate, privately negotiated
agreements to exchange $117.8 million of the original $170.0 million of 2.25%
convertible subordinated notes due 2013 ("CSN I") for an equivalent principal
amount of a new series of 2.25% convertible subordinated notes due 2013. The
primary purpose of this transaction was to eliminate the June 15, 2010 call and
put option that is included in the terms of CSN I. This exchange was accounted
for as an extinguishment of debt and resulted in a net pre-tax gain of $4.5
million ($2.9 million net of tax) or $0.11 per diluted share.

Provision for income taxes

Our effective tax rate for the first quarter of 2007 was 32.5% compared to 34.5%
for the same period of 2006. This decrease was primarily a result of our
estimated increase in R&D tax credits and the Qualified Production Activities
Deduction for 2007.

                                      -29-

Subsequent Events

On April 3, 2007, the Company acquired substantially all of the assets of
BIOMEC, Inc. ("BIOMEC") for $11.4 million in cash and future additional
consideration. BIOMEC has grants in place that will fund substantially all of
its development costs through 2008. Currently, the engineering team is working
on various projects, including a novel-polymer coating (biomimetic) that mimics
the surface of endothelial cells of blood vessels. Additionally, BIOMEC has a
product development agreement and a 20% investment partnership in IntElect
Medical, Inc., an early stage neurostimulation device company that works in
conjunction with the Cleveland Clinic. This transaction was accounted for under
the purchase method of accounting.

On April 30, 2007, the Company jointly announced with Enpath Medical, Inc.
("Enpath") that they have entered into a definitive merger agreement under which
the Company will acquire Enpath for $14.38 per share in cash, or approximately
$102 million, including assumption of debt. Under the terms of the agreement,
the Company will commence a tender offer for all of Enpath's outstanding shares
no later than May 8, 2007. The transaction is subject to customary closing
conditions and regulatory approvals and the tender of a majority of Enpath's
outstanding shares, on a fully diluted basis. The purchase price will be funded
out of the Company's available cash and short-term investments. The transaction
is expected to close in late June. Enpath is a medical products company engaged
in designing, developing, manufacturing and marketing single use medical device
products for the cardiac rhythm management, neuromodulation and interventional
radiology markets.

(a)  Short-term investments consist of investments acquired with maturities that
     exceed three months and are less than one year at the time of acquisition,
     equity securities classified as available-for-sale, and auction rate
     securities.
(b)  Cash and cash equivalents and working capital increased primarily due to
     $76.0 million of net cash received from the issuance of additional 2.25%
     convertible subordinated notes due 2013 in March 2007.

Revolving Line of Credit

The Company maintains a three-year $50 million Revolving Credit Facility (the
"Revolver"), which contains a $10.0 million sub-limit for the issuance of
commercial or standby letters of credit. The Revolver is secured by the
Company's non-realty assets including cash, accounts and notes receivable, and
inventories and has an expiration date of May 31, 2008. The Revolver requires
compliance with two quarterly financial covenants, as defined. The first relates
to the ratio of consolidated net earnings or loss before interest, taxes,
depreciation, and amortization ("EBITDA") to fixed charges. The second is a
leverage ratio, which is calculated based on the ratio of consolidated funded
debt less cash, cash equivalent investments and short-term investments to
consolidated EBITDA. Interest rates under the Revolver vary with the Company's
leverage. The Company is required to pay a commitment fee of between 0.125% and
0.250% per annum on the unused portion of the Revolver based on the Company's
leverage. As of March 30, 2007, the Company had no balance outstanding on the
Revolver.

In April 2007, the Company signed a commitment letter for a new five-year senior
credit facility (the "Credit Facility") consisting of a $235 million revolving
credit facility, which can be increased to $335 million upon the Company's
request. The Credit Facility also contains a $15 million letter of credit
subfacility and a $15 million swingline subfacility. This Credit Facility will
replace the $50 million Revolver and has similar financial covenants, interest
rates, commitment fees and prioritization as the Revolver. The Company expects
that this agreement will become effective in the second quarter of 2007.

                                      -30-


Our principal sources of liquidity are our operating cash flow combined with our
working capital of $225.7 million at March 30, 2007 and availability under our
Revolver. Historically we have generated cash from operations sufficient
to meet our capital expenditure and debt service needs, other than for
acquisitions. At March 30, 2007, our current ratio was 6.3:1.0. As discussed
above, subsequent to the end of the first quarter, the Company acquired
substantially all of the assets of BIOMEC for $11.4 million in cash and future
additional consideration and entered into a definitive merger agreement to
acquire Enpath for approximately $102 million in cash, including the assumption
of debt. These transactions will be funded with the Company's cash and cash
equivalents and short-term investments available for sale. The Company regularly
engages in discussions relating to potential acquisitions and may announce
additional acquisition transactions at any time.

Operating activities

Net cash flows from operating activities for the three months ended March 30,
2007 increased $12.2 million over the comparable period in 2006. This was
primarily the result of a decrease in inventory levels due to increased sales
and a decreased accounts receivable change compared to the first quarter of
2006. The $4.5 million ($2.9 million net of tax) non-cash gain on the
extinguishment of debt during the first quarter of 2007 resulted in a
reclassification of approximately $11.3 million of income tax liability, which
is payable in 2007. This amount was previously recorded as a non-current
deferred tax liability on the balance sheet.

Investing activities

The majority of the acquisition of property, plant and equipment for the first
three months of 2007 was related to routine purchases made in order to support
our internal growth and to maintain our technology leadership. We expect these
purchases to increase in the future as we begin construction of a new 80,000
square foot manufacturing facility in the Massachusetts area in June of this
year. In addition to a new expanded facility, we will also be investing in
semi-automation equipment. The expected completion of this $28 million expansion
project is mid-2008. We expect to use $113.4 million of cash and cash
equivalents and short term investments available for sale to fund the
acquisition of BIOMEC and Enpath in the second quarter of 2007.

Net cash invested in short-term instruments during the first three months of
2007 of $7.5 million is primarily a result of the investment of excess cash flow
from operations.

Financing activities

Cash flow from financing activities for the first quarter of 2007 was primarily
related to the issuance of $80.0 million of additional 2.25% convertible
subordinated notes due 2013 at a price of $950 per $1,000 of principal. The
Company has incurred approximately $4.3 million of financing fees related to
this transaction which will be paid in the second quarter of 2007. Additionally,
cash flows from financing activities included cash received from non-qualified
stock option exercises for both 2007 and 2006.

Capital Structure

At March 30, 2007, our capital structure consisted of $240.1 million of
convertible subordinated notes and our 22.3 million shares of common stock
outstanding. We have $225.7 million in cash, cash equivalents and short-term
investments and are in a position to finance our future acquisitions. We are
also authorized to issue 100 million shares of common stock and 100 million
shares of preferred stock. The market value of our outstanding common stock
since our IPO has exceeded our book value; accordingly, we believe that if
needed we can access public markets to sell additional common or preferred stock
assuming conditions are appropriate. Our capital structure allows us to support
our internal growth and provides liquidity for corporate development
initiatives. Our current expectation for 2007 is that capital spending will be
in the range of $35.0 million to $45.0 million, of which $20.0 million is
attributable to the ECP expansion.

                                      -31-


Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements within the meaning of Item 303(a)(4)
of Regulation S-K.

Contractual Obligations

In the normal course of business, the Company makes routine purchase commitments
(primarily equipment and raw material purchases) in order to maintain the
technological leadership of its manufacturing facilities and meet the needs of
its customers. As of March 30, 2007, total contractual obligations related to
such expenditures are approximately $10.5 million and will be financed by
existing cash, short-term investments, or cash generated from operations.

Inflation

We do not believe that inflation has had a significant effect on our operations.

Impact of Recently Issued Accounting Standards

In February 2007, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No 159, The Fair Value
Option for Financial Assets and Financial Liabilities--Including an amendment of
FASB Statement No. 115. This Statement provides entities with an option to
choose to measure eligible items at fair value at specified election dates. If
elected, an entity must report unrealized gains and losses on the item in
earnings at each subsequent reporting date. The fair value option: may be
applied instrument by instrument, with a few exceptions, such as investments
otherwise accounted for by the equity method; is irrevocable (unless a new
election date occurs); and is applied only to entire instruments and not to
portions of instruments. The Company is still evaluating the impact of SFAS No.
159 on its financial statements, which is effective beginning in fiscal year
2008.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements. This
Statement defines fair value, establishes a framework for measuring fair value
while applying generally accepted accounting principles, and expands disclosures
about fair value measurements. SFAS No. 157 establishes a fair value hierarchy
that distinguishes between (1) market participant assumptions based on market
data obtained from independent sources and (2) the reporting entity's own
assumptions developed based on unobservable inputs. The Company is still
evaluating the impact of SFAS No. 157 on its financial statements, which is
effective beginning in fiscal year 2008.

Application of Critical Accounting Estimates

Our unaudited condensed consolidated financial statements are based on the
selection of accounting policies and the application of significant accounting
estimates, some of which require management to make significant assumptions. We
believe that some of the more critical estimates and related assumptions that
affect our financial condition and results of operations are in the areas of
inventories, goodwill and other indefinite lived intangible assets, long-lived
assets, share-based compensation and income taxes. For further information,
refer to Item 7 "Managements Discussion and Analysis of Financial Condition and
Results of Operations" and Item 8 "Financial Statements and Supplementary Data"
in the Company's Annual Report on Form 10-K for the year ended December 29,
2006.

                                      -32-


During the three months ended March 30, 2007, we did not change or adopt new
accounting policies that had a material effect on our consolidated financial
condition and results of operations.

Effective in the first quarter of 2007, the Company adopted the provisions of
FASB Interpretation ("FIN") No. 48 Accounting for Uncertainty in Income Taxes,
an interpretation of FASB SFAS No. 109. FIN No. 48 clarifies the accounting for
uncertainty in income taxes recognized under SFAS 109. FIN No. 48 prescribes a
recognition threshold and measurement attribute for financial statement
recognition and measurement of a tax position taken or expected to be taken in a
tax return and also provides guidance on various related matters such as
derecognition, interest and penalties, and disclosure.

Upon adoption of FIN No. 48, the Company did not recognize any adjustment to its
$1.8 million of unrecognized tax benefits, all of which would favorably impact
the effective tax rate (net of federal benefit on state issues), if recognized.
The Company's unrecognized tax benefits consist of refund claims which did not
meet the more likely than not threshold under FIN No. 48. At the end of the
first quarter, there was no change in the balance of unrecognized tax benefits.
The Company anticipates that the total unrecognized tax benefits could
significantly change within the next twelve months due to the settlement of
audits/appeals currently in process, however, quantification of an estimated
range cannot be made at this time.

The Company will recognize interest expense related to uncertain tax positions
as Interest Expense. Penalties, if incurred, would be recognized as a component
of Selling, General and Administrative Expenses. At the end of the first
quarter, there was no accrued interest or penalties related to uncertain tax
positions. The tax years 2003-2006 remain open to examination by the major
taxing jurisdictions to which we are subject. The 2001 and 2002 tax years remain
open in certain jurisdictions as a result of audits/appeals currently in
process.

Forward-Looking Statements

Some of the statements contained in this Quarterly Report on Form 10-Q and other
written and oral statements made from time to time by us and our representatives
are not statements of historical or current fact. As such, they are
"forward-looking statements" within the meaning of Section 27A of the Securities
Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934,
as amended. We have based these forward-looking statements on our current
expectations, which are subject to known and unknown risks, uncertainties and
assumptions. They include statements relating to:

     o    future sales, expenses and profitability;
     o    the future development and expected growth of our business and the
          industries we operate in;
     o    our ability to successfully execute our business model and our
          business strategy;
     o    our ability to identify trends within the implantable medical devices,
          medical components, and commercial power sources industries and to
          offer products and services that meet the changing needs of those
          markets;
     o    projected capital expenditures; and
     o    trends in government regulation.

You can identify forward-looking statements by terminology such as "may,"
"will," "should," "could," "expects," "intends," "plans," "anticipates,"
"believes," "estimates," "predicts," "potential" or "continue" or the negative
of these terms or other comparable terminology. These statements are only
predictions. Actual events or results may differ materially from those suggested
by these forward-looking statements. In evaluating these statements and our
prospects generally, you should carefully consider the factors set forth below.
All forward-looking statements attributable to us or persons acting on our
behalf are expressly qualified in their entirety by these cautionary factors and

                                      -33-


to others contained throughout this report. We are under no duty to update any
of the forward-looking statements after the date of this report or to conform
these statements to actual results.

Although it is not possible to create a comprehensive list of all factors that
may cause actual results to differ from the results expressed or implied by our
forward-looking statements or that may affect our future results, some of these
factors include the following: dependence upon a limited number of customers,
product obsolescence, inability to market current or future products, pricing
pressure from customers, reliance on third party suppliers for raw materials,
products and subcomponents, fluctuating operating results, inability to maintain
high quality standards for our products, challenges to our intellectual property
rights, product liability claims, inability to successfully consummate and
integrate acquisitions, unsuccessful expansion into new markets, competition,
inability to obtain licenses to key technology, regulatory changes or
consolidation in the healthcare industry, and other risks and uncertainties that
arise from time to time as described in the Company's Annual Report on Form 10-K
and other periodic filings with the Securities and Exchange Commission.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Under our line of credit any borrowings bear interest at fluctuating market
rates. At March 30, 2007, we did not have any borrowings outstanding under our
line of credit and thus no interest rate sensitive financial instruments other
than short-term investments. We do not believe that the impact of fluctuations
in interest rates on our short-term investments will have a material effect on
our condensed consolidated financial statements.

The company incurs certain expenses related to the Tijuana operations that are
denominated in a foreign currency. We do not believe that the impact of foreign
currency fluctuations will have a material effect on our condensed consolidated
financial statements.

     -------------------------------------------------

     Our management, including the principal executive officer and principal
     financial officer, evaluated our disclosure controls and procedures (as
     defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act
     of 1934) related to the recording, processing, summarization and reporting
     of information in our reports that we file with the SEC as of March 30,
     2007. These disclosure controls and procedures have been designed to
     provide reasonable assurance that material information relating to us,
     including our subsidiaries, is made known to our management, including
     these officers, by other of our employees, and that this information is
     recorded, processed, summarized, evaluated and reported, as applicable,
     within the time periods specified in the SEC's rules and forms.

     Based on their evaluation, as of March 30, 2007, our principal executive
     officer and principal financial officer have concluded that our disclosure
     controls and procedures are effective.

b.   Changes in Internal Control Over Financial Reporting.

     There have been no changes in our internal control over financial reporting
     that occurred during our last fiscal quarter to which this Quarterly Report
     on Form 10-Q relates that have materially affected, or are reasonably
     likely to materially affect, our internal control over financial reporting.

There have been no material changes in risk factors as previously disclosed in

We face risks associated with our proposed acquisition of Enpath Medical, Inc.

Our proposed acquisition of Enpath Medical, Inc. ("Enpath") presents several
risks and uncertainties, including the following:

     o    We may not consummate the acquisition or it may be delayed, for
          reasons beyond our control, and we may incur costs that may not be
          reimbursed;
     o    The allocation of the purchase price to Enpath's assets, the
          amortization of intangible assets resulting from that allocation and
          the impact of fair value purchase accounting adjustments may adversely
          affect our earnings;
     o    We may be unsuccessful in integrating Enpath's business;
     o    Integrating Enpath's business may be distractive to our management and
          disruptive to our business and the costs of integration may be
          significant; and
     o    We may assume liabilities in the Enpath acquisition that we did not
          anticipate that could have a material adverse effect on our operating
          results.
