                                GREATBATCH, INC.
        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- Unaudited
- --------------------------------------------------------------------------------

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 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. (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. For further
   information, refer to the consolidated financial statements and notes thereto
   included in the Company's Annual Report on Form 10-K for the year ended
   December 31, 2004. We anticipate amending our Form 10-K for the year ended
   December 31, 2004 in the near future. See Form 8-K filed on November 9, 2005
   for additional information.

   The Company officially changed its name to Greatbatch, Inc. from Wilson
   Greatbatch Technologies, Inc. during the second quarter of 2005.

   Certain reclassifications were made to the prior period Condensed
   Consolidated Statement of Cash Flows to conform with the current period
   presentation. This reclassification did not affect net income or
   stockholders' equity.

   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. For clarity of presentation, the Company describes all periods as if
   each quarter end is March 31st, June 30th and September 30th and as if the
   year-end is December 31st. The third quarter of 2005 and 2004 each contained
   13 weeks.

2. STOCK-BASED COMPENSATION

   The Company accounts for stock-based compensation in accordance with
   Statement of Financial Accounting Standards No. 123, Accounting for
   Stock-Based Compensation ("SFAS No. 123"). As permitted in SFAS No. 123, the
   Company has chosen to account for stock-based compensation using the
   intrinsic value method prescribed in Accounting Principles Board No. 25,
   Accounting for Stock Issued to Employees, and related interpretations.

                                      - 6 -


   The Company has determined the pro forma information as if the Company had
   accounted for stock options granted under the fair value method of SFAS No.
   123. The Black-Scholes option-pricing model was used with the following
   weighted average assumptions.

   These pro forma calculations assume the common stock is freely tradable for
   all periods presented and, as such, the impact is not necessarily indicative
   of the effects on reported net income of future periods.

   Revolving Line of Credit

   On May 31, 2005, the Company amended its Senior Secured Credit Facility,
   which included changes to the underlying covenants. The amended facility
   replaced the old $20.0 million revolving credit facility with a new
   three-year $50.0 million Revolving Credit Facility ("new revolver"), which
   contains a $10.0 million sub-limit for the issuance of commercial or standby
   letters of credit. The new revolver is secured by the Company's non-realty
   assets including cash, accounts and notes receivable, and inventories. The
   new revolver requires the Company to comply 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 new revolver vary with the Company's leverage. The
   Company is required to pay a commitment fee of between .125% and .250% per
   annum on the unused portion of the new revolver based on the Company's
   leverage. As of September 30, 2005, the Company had no balance outstanding on
   the new revolver.

   Debt issue expenses for the new revolver totaled $0.2 million and are being
   amortized using the straight-line method over a three-year term. The revolver
   refinancing transaction resulted in the write-off of $0.1 million of existing
   deferred financing fees associated with the prior revolving line of credit.

   Capital Expenditures -- During 2004, the Company commenced the build out of
   its medical battery and capacitor manufacturing facility in Alden, NY and its
   value-add manufacturing facility in Tijuana, Mexico. These facilities will
   enable the Company to further consolidate its operations and implement state
   of the art manufacturing capabilities at both locations. The total remaining
   contractual obligation for construction of these facilities at September 30,
   2005 is $3.4 million and will be financed by existing cash, short-term
   investments, or cash generated from operations.


11. BUSINESS SEGMENT INFORMATION

   The Company operates its business in two reportable segments: Implantable
   Medical Components ("IMC") and Electrochem Commercial Power ("ECP"),
   (formerly "Electrochem Power Solutions"). The IMC segment designs and
   manufactures critical components used in implantable medical devices. The
   principal components are batteries, capacitors, filtered feedthroughs, coated
   components, enclosures and machined and molded precision components. The
   principal medical devices are pacemakers, defibrillators and
   neurostimulators. The ECP segment designs and manufactures high performance
   cells and battery packs; principal markets for these products are for oil and
   gas exploration, oceanographic equipment, and aerospace.

   The Company defines segment income from operations as gross profit less costs
   and expenses attributable to segment-specific selling, general and
   administrative, research, development and engineering expenses, intangible
   amortization and other operating expenses. Segment income also includes a
   portion of non-segment specific selling, general and administrative, and
   research, development and engineering expenses based on allocations
   appropriate to the expense categories. The remaining unallocated operating
   expenses along with other income and expense are not allocated to reportable
   segments. Transactions between the two segments are not significant. The
   accounting policies of the segments are the same as those described and
   referenced in Note 1.

   (a) Severance charges. During the first quarter of 2005, the Company
   implemented a 4% workforce reduction as a continuation of cost containment
   efforts initiated mid-year 2004, which resulted in a severance charge of $1.5
   million.

   Accrued liabilities at September 30, 2005 related to the severance charges

   (b) Alden Facility Consolidation -- On February 23, 2005, the Company
   announced its intent to consolidate the medical capacitor manufacturing
   operations, currently in Cheektowaga, NY, and the implantable medical battery
   manufacturing operations, currently in Clarence, NY, into the advanced power
   source manufacturing facility in Alden, NY ("Alden Facility"). The Company is
   also consolidating the capacitor research, development and engineering
   operations from the Cheektowaga, NY, facility into the existing implantable
   medical battery research, development, and engineering operations in
   Clarence, NY.

   The total cost estimated for these consolidation efforts is anticipated to be
   between $3.5 and $4.0 million. The Company expects to incur and pay the
   remaining cost in the next two quarters. The expenses for the Alden Facility
   consolidation are included in the IMC business segment. The major categories
   of costs, which will primarily be cash expenditures, include the following:

                                     - 14 -



   o  Production inefficiencies and revalidation -- $1.5 to $1.7 million;

   (c) Carson City Facility shutdown and (d) Tijuana Facility consolidation - 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 the
   Carson City Facility into the Tijuana, Mexico facility ("Tijuana Facility").

   The total estimated cost for this facility consolidation plan is anticipated
   to be between $4.5 million and $5.4 million. The Company expects to incur and
   pay the remaining cost over the next three fiscal quarters. The major
   categories of costs include the following:

   o  Costs related to the shutdown of the Carson City Facility:

      a. Severance and retention -- $1.4 to $1.6 million;

      b. Accelerated depreciation -- $0.5 to $0.6 million; and

      c. Other -- $0.6 to $0.7 million.

   o Costs related to the Tijuana Facility consolidation:

      a. Production inefficiencies and revalidation -- $0.4 to $0.5 million;

      b. Relocation and moving -- $0.3 to $0.5 million;

      c. Personnel (including travel, training and duplicate wages) -- $1.0 to
         $1.1 million; and

      d. Other - $0.3 to $0.4 million.

   All categories of costs are considered to be cash expenditures, except
   accelerated depreciation. The expenses for the Carson City facility shutdown
   and the Tijuana Facility consolidation are included in the IMC business
   segment.

   Other Tijuana start-up expenses (not associated with Carson City
   consolidation) amount to $865 thousand.

   (e) Costs to exit development agreement. There was a $1.15 million charge
   recorded in other operating expenses for the IMC segment during the second
   quarter for charges associated with the discontinuation of a drug pump
   development agreement.

   (f) Asset dispositions. Third quarter and year-to-date amounts include $2.8
   million write-down of automated cathode assembly equipment for the IMC
   segment during the third quarter of 2005. This charge was primarily related
   to a decision not to continue to use some battery production equipment. The
   manufacturing process related to this equipment did not match the Company's
   overall manufacturing strategy. The remainder of the expense is for other
   property, plant, and equipment dispositions.


13. IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

   In June 2005 the Financial Accounting Standards Board ("FASB") issued
   Statement of Financial Accounting Standards ("SFAS") No. 154, Accounting
   Changes and Error Corrections, ("SFAS 154") a replacement of APB Opinion No.
   20, Accounting Changes, and Statement No. 3, Reporting Accounting Changes in
   Interim Financial Statements. SFAS 154 changes the requirements for the
   accounting for and the reporting of a change in accounting principle.
   Previously, most voluntary changes in accounting principles required
   recognition by recording a cumulative effect adjustment within net income in

                                     - 16 -



   the period of change. SFAS 154 requires retrospective application to prior
   periods' financial statements, unless it is impracticable to determine either
   the specific period effects or the cumulative effect of the change. SFAS 154
   is effective for accounting changes made in fiscal years beginning after
   December 15, 2005. The Company does not expect that adoption of SFAS No. 154
   will have a material effect on its consolidated financial position,
   consolidated results of operations, or liquidity.

   In March 2005, the FASB issued Interpretation No. 47, "Accounting for
   Conditional Asset Retirement Obligations, an interpretation of FASB Statement
   No. 143" ("FIN 47"). FIN 47 requires the recognition of a liability for the
   fair value of a legally-required conditional asset retirement obligation when
   incurred, if the liability's fair value can be reasonably estimated. FIN 47
   is effective for fiscal years ending after December 15, 2005. The Company
   does not expect that adoption of FIN 47 will have a material effect on its
   consolidated financial position, consolidated results of operations, or
   liquidity.

   In December 2004, the FASB issued SFAS No. 123 (revised 2004), Share-Based
   Payment ("SFAS No. 123(R)"). This statement is a revision of SFAS No. 123,
   Accounting for Stock-Based Compensation, and supersedes APB Opinion No. 25,
   Accounting for Stock Issued to Employees. This standard requires the Company
   to measure the cost of employee services received in exchange for equity
   awards based on the grant date fair value of the awards. The cost will be
   recognized as compensation expense over the vesting period of the awards.

   The Company anticipates adopting the provisions of SFAS No. 123(R) on January
   1, 2006 using the modified prospective method. Accordingly, compensation
   expense will be recognized for all newly granted awards and awards modified,
   repurchased, or cancelled after January 1, 2006. Compensation cost for the
   unvested portion of awards that are outstanding as of January 1, 2006 will be
   recognized ratably over the remaining vesting period. The compensation cost
   for the unvested portion of awards will be based on the fair value at date of
   grant as calculated for the Company's pro forma disclosure under SFAS 123.

   The Company estimates that the effect on net income and earnings per share in
   the periods following adoption of SFAS 123(R) will be consistent with the
   Company's pro forma disclosure under SFAS No. 123, except that estimated
   forfeitures will be considered in the calculation of compensation expense
   under SFAS 123(R). Additionally, the actual effect on net income and earnings
   per share will vary depending upon the number of options granted in
   subsequent periods compared to prior years.

   In November 2004, the FASB issued SFAS No. 151, Inventory Costs, an amendment
   of ARB No. 43, Chapter 4 ("SFAS No. 151"). SFAS No. 151 amends the guidance
   in ARB No. 43, Chapter 4, "Inventory Pricing," to clarify the accounting for
   abnormal amounts of idle facility expense, handling costs and wasted material
   (spoilage). Among other provisions, the new rule requires that such items be
   recognized as current-period charges, regardless of whether they meet the
   criterion of "so abnormal" as stated in ARB No. 43. SFAS No. 151 is effective
   for fiscal years beginning after June 15, 2005. The company does not expect
   that adoption of SFAS No. 151 will have a material effect on its consolidated
   financial position, consolidated results of operations, or liquidity.

                                     - 17 -



14. RESTATEMENTS

   The Company has restated its condensed consolidated balance sheet as of
   December 31, 2004 to change the classification of auction rate securities
   from cash and cash equivalents to short-term investments. Auction rate
   securities are securities that have stated maturities beyond three months,
   but are priced and traded as short-term investments due to the liquidity
   provided through the auction mechanism that generally resets interest rates
   every 7 to 35 days. Although management had determined the risk of failure of
   an auction process to be remote, the definition of a cash equivalent in SFAS
   No. 95, Statement of Cash Flows, requires reclassification to short-term
   investments. The condensed consolidated cash flow statement for the nine
   month period ended September 30, 2004 has also been restated in order to
   conform to this change in classification. Due to the short term nature of the
   interest rate resets, the fair market value of the auction rate securities
   approximates their recorded value.

   During the quarter ended September 30, 2005, the Company determined that it
   had not accounted for a deferred tax asset in purchase accounting related to
   net operating losses acquired in the Company's acquisition of NanoGram in
   2004. The recording of these net operating losses decreased long-term
   deferred income tax liabilities and correspondingly decreased goodwill.

   The restatements have been made to the unaudited Condensed Consolidated
   Balance Sheet and Condensed Consolidated Statement of Cash Flows as follows:

15. SUBSEQUENT EVENT

   On October 25, 2005, the Company and Medtronic, Inc. ("Medtronic") entered
   into a license agreement which grants Medtronic the right to use certain
   intellectual property relating to tantalum capacitors. The license is
   perpetual and, except for the Company's right to make and sell capacitors,
   exclusive to Medtronic. The license provides for an initial license fee
   (due after Medtronic's first US sale) and royalties (some of which the
   Company must pay to a third party). The royalties are subject to a maximum
   royalty amount and may be eliminated within specified contract periods if
   Medtronic purchases a certain percentage of its tantalum capacitor
   requirements from the Company. The Company cannot provide any assurances
   that Medtronic will utilize its capacitor technology or purchase any
   capacitors. The Company does not anticipate any significant financial
   impact from this agreement in the near term.

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

Introduction

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 for
IMDs and enable our customers to introduce IMDs that are progressively smaller,
longer lasting, more efficient and more functional. We also leverage our core
competencies in technology and manufacturing through our Electrochem Commercial
Power ("ECP") business (formerly "Electrochem Power Solutions") to develop and
produce cells and battery packs for commercial applications that demand high
performance and reliability, including oil and gas exploration, oceanographic
equipment and aerospace.

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.

We utilize a fifty-two, fifty-three week fiscal year ending on the Friday
nearest December 31st. For 52-week years, each quarter contains 13 weeks. For
clarity of presentation, we describe all periods as if each quarter end is March
31st, June 30th and September 30th and as if the year-end is December 31st. The
third quarters of 2005 and 2004 each contained 13 weeks.

The commentary that follows should be read in conjunction with our consolidated
financial statements and related notes and with the Management's Discussion and
Analysis of Financial Condition and Results of Operations contained in our Form
10-K for the fiscal year ended December 31, 2004. We anticipate amending our
Form 10-K for the year ended December 31, 2004 in the near future. See Form 8-K
filed on November 9, 2005 for additional information.

Overview

During and subsequent to the third quarter 2005, there were several developments
affecting our business:

   o  Achieved sales growth of 38% consisting of 43% growth in Implantable
      Medical Components and 11% growth in Electrochem Commercial Power
      products.

   o  Installation of the remaining assembly equipment at the Greatbatch Mexico
      facility is expected to be completed in the fourth quarter of 2005. The
      move of the filtered feedthrough operation in Carson City to Tijuana is
      progressing as planned. Manufacturing equipment is currently being
      installed and validated. The project is expected to be completed in its
      entirety during the first half of 2006.


                                     - 20 -



   o  The move of the manufacturing equipment from the existing capacitor plant
      to the Alden facility is in process. The move is expected to essentially
      be complete by the end of the fourth quarter of 2005. However, due to
      increased capacitor volume, the final manufacturing equipment moves may
      extend into next year to ensure production requirements are met.

   o  On October 25, 2005, the Company and Medtronic, Inc. entered into a
      royalty-based licensing agreement with respect to certain intellectual
      property pertaining to tantalum capacitors. The use of tantalum technology
      and any purchase of tantalum capacitors by Medtronic are subject to their
      further evaluation.

IMC. As mentioned in our annual report (which is available on our website,
www.greatbatch.com), 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. While companies typically announce new products
that have modest improvements in form and/or function regularly, we believe the
Q-Series firmly establishes a new industry standard. 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).

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, 2 of these new cells are capable of providing power for the entire
10-year life of the telematics device. ECP 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.

ECP 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 third quarter 2005, we recorded charges in other operating expense
related to our ongoing cost savings and consolidation efforts.

Severance charges. The Company implemented a 4% workforce reduction during the
first quarter of 2005, which resulted in a severance charge of $1.5 million. Of
that amount, $0.8 million, $0.5 million, and $0.2 million were paid in cash
during the first, second and third quarters, respectively.

Alden Facility Consolidation. On February 23, 2005, we announced our intent to
consolidate the medical capacitor manufacturing operations, currently in
Cheektowaga, NY, and the implantable medical battery manufacturing operations,
currently in Clarence, NY, into the advanced power source manufacturing facility
in Alden, NY ("Alden Facility"). We are also consolidating the capacitor
research, development and engineering operations from the Cheektowaga, NY,
facility into the existing implantable medical battery research, development,
and engineering operations in Clarence, NY.

The total cost estimated for these consolidation efforts is anticipated to be
between $3.5 million and $4.0 million. Expenses of $2.3 million have been
incurred through the third quarter. Of these, $1.2 million were paid in cash,
$0.4 million were for assets written-off, and $0.7 million remain to be paid. We
expect to incur the remaining expense over the next two fiscal quarters.

Carson City Facility shutdown and Tijuana Facility consolidation. On March 7,
2005, we announced our intent to close the Carson City, NV facility ("Carson
City Facility") and consolidate the work performed at the Carson City Facility
into the Tijuana, Mexico facility ("Tijuana Facility").

The total estimated cost for this facility consolidation plan is anticipated to
be between $4.5 million and $5.4 million, comprised of between $2.5 million to
$2.9 million for the Carson City Facility shutdown and $2.0 million to $2.5
million for the Tijuana Facility consolidation. We expect to incur the remaining
costs over the next three fiscal quarters. All categories of costs are
considered to be cash expenditures, except accelerated depreciation.

Carson City Facility shutdown expenses of $1.8 million have been accrued year to
date, of which $0.2 million were paid in cash, $0.4 million have been recorded
as accelerated depreciation and $1.2 million remain to be paid. Tijuana Facility
consolidation expenses of $0.7 million have been incurred and paid year to date.

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.

The results for the third quarter of 2005 did receive benefit from the field
issues surrounding ICD products. However, it is extremely difficult to identify
how much benefit we received during the third quarter. We do not have specific
information on the nature of the orders and can only assume that some percentage
of the increase relates to the ICD field actions in the marketplace. It is
likely that the impact on our sales will continue to be favorably affected by
these field issues into the fourth quarter.

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.
These dynamics should be become clearer in early 2006 and will have to be
carefully considered when we provide our 2006 outlook.

Moving beyond the field actions, the increase in demand is not isolated to any
one customer. We are seeing strength across all of our products and our entire
customer base. We believe that the market continues to exhibit strong underlying
growth fundamentals (as evidenced by the increased number of CRM device
implants) and that we are well positioned to participate in this market growth.

The increase in IMC sales of 43% during the third quarter was primarily due to
increased demand for ICD batteries, filtered feedthroughs, feedthroughs, and wet
tantalum capacitors offset by an average 1% reduction in selling prices.

The increase in IMC sales of 19% for the year to date were primarily due to
increased demand for ICD batteries, filtered feedthroughs, coated components and
medical enclosures offset by an average 2% reduction in selling prices.

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.

The ECP sales increases of 11% in the third quarter and 19% year to date have
been driven by volume increases due to a number of factors.

First and foremost, we have expanded our commercial sales force. We are
aggressively pursuing new business opportunities and have been successful on
many of these fronts.

Second, we have significantly reduced our manufacturing lead times at our
Canton, Massachusetts facility, which has allowed us to be more responsive to
our customers needs. We will continue to expand on these efforts from various
lean manufacturing initiatives that are underway in our Canton facility and
throughout the Company.

The third factor that has contributed to our positive commercial results has
been favorable market dynamics. The oil and gas exploration market remains
robust due to the increased demand for products used in pipeline inspections,
pressure monitoring and measurement while drilling applications. In addition, we
have seen an increase in demand for power sources used in wave monitoring and
seismic recording, due to increased Tsunami related concerns, mainly in the
international markets.

Gross profit

The basis point impact in gross margin for the third quarter and year to date
2005 were primarily due to the following factors:

1) This improvement in gross margin is primarily due to the fact that as
   production volumes increase, fixed costs such as plant overhead and
   depreciation do not increase at the same rate.
2) During 2005, two facilities are not being utilized to their full capacity.
   The capacitor facility was initially established to handle higher levels of
   production quantities. The capacitor facility is expected to be fully
   consolidated into the Alden facility by the end of the first quarter 2006.
   This should eliminate the costs associated with the original capacitor
   facility. The Tijuana facility is new for 2005 and as a result its floor


                                     - 25 -


   space and infrastructure are considered under utilized at this time. The
   production of filtered feedthroughs (currently being performed in Carson
   City) is in the process of being relocated to the Tijuana facility.
3) Sales prices for Implantable Medical Components are subject to pricing
   agreements with customers. Many times these agreements allow for changes in
   price due to customer specific levels of demand.
4) Based on a several metrics, this year's profit sharing and incentive
   calculations are estimated to be higher than in 2004.
5) Some of the Company's products utilize platinum as a raw material product.
   The cost of platinum to the company has increased in 2005.
6) On a year to date basis, the percentage of higher margin products sold has
   decreased in comparison to the same nine month period in 2004.

SG&A expenses

The increase in SG&A expenses for the third quarter and year to date 2005 is
primarily due to the following factors (in thousands):

The increase in RD&E expenses in the third quarter is primarily due to increased
personnel costs for research and development programs, coupled with decreased
reimbursement on new product development projects in the current quarter
compared to last year. In terms of the development costs billed, reimbursements
for development projects were 38% lower in the current quarter due to the timing
of the achievement of revenue milestones. Reimbursements for achieving certain
development milestones are netted against gross spending. We expect that RD&E
costs will increase in the fourth quarter similar to the third quarter due to
increased investment in future development programs.

Gross RD&E spending declined by 3% for the year to date versus last year. The
majority of this decrease is due to the QHR battery product line moving from the
development stage into production. Reimbursements year to date were 45% higher
in 2005 in comparison to 2004 due to a significant new development project in
2005.

Amortization expense

Amortization expense for the third quarter of 2005 declined as the result of the
completion of amortization of a noncompete/employment agreement during 2004. The
result is a $0.1 million reduction in amortization expense per quarter in 2005.

Amortization expense for the year to date reflects an incremental $0.3 million
of intangible asset amortization resulting from the NanoGram acquisition in
March 2004 offset by the $0.3 million reduction of expense due to the completion
of the amortization of the noncompete/employment agreement during 2004.

Other operating expense

Other operating expense for the quarter and year to date 2005 is comprised of
the following costs (in millions):

                                        Quarter    Year to Date

Severance *                                     -          1.5
Alden facility consolidation *        $       1.4  $       2.3
Carson City facility shutdown *               0.9          1.8
Costs to exit development agreement             -          1.2
Tijuana start-up *                            1.0          1.5
Asset dispositions                            4.5          5.9
                                      ------------ ------------
                                      $       7.8  $      14.2
                                      ============ ============

The $1.2 million charge for "costs to exit a development agreement" was recorded
in other operating expenses during the second quarter of 2005 for charges
associated with the discontinuation of a drug pump development agreement.

The "asset dispositions" caption includes a $2.8 million write-down of automated
cathode assembly equipment. This charge was primarily related to a decision not


                                     - 27 -


to continue to use some battery production equipment. The manufacturing process
related to this equipment did not match our overall manufacturing strategy.

Refer to "Cost savings and consolidation efforts" discussion for disclosure
related to the timing and level of remaining expenditures for items marked with
"*".

In 2004, charges of $2.0 million related to the acquisition of a patent and $0.8
million for severance costs were recorded in the second quarter of 2004.

Interest expense and interest income

Interest expense increased during the third quarter of 2005 and year to date in
2005 in comparison to the corresponding periods in 2004 due to the incremental
deferred financing fees amortization related to the new revolving credit
facility.

Interest income increased during the third quarter of 2005 and year to date 2005
in comparison to the corresponding periods in 2004 due to higher interest rates
as well as the movement of investments in mid-2004 from tax deferred to taxable
securities, which bear higher rates of return.

Provision for income taxes

Our effective tax rate is below the United States statutory rate primarily as a
result of federal research and development tax credits and the allowable
Extraterritorial Income Exclusion ("ETI") for 2005. In comparison to last year,
the year to date effective tax rate was within 0.5% of the 2004 effective tax
rate.

Liquidity and Capital Resources

The following liquidity and capital resources discussion has been updated for
the effects of the restatement discussed in Note 14 to the condensed
consolidated financial statements.

Revolving Line of Credit

On May 31, 2005, we amended our Senior Secured Credit Facility, which included
changes to the underlying covenants. The amended facility replaced the old $20.0
million revolving credit facility with a new three-year $50.0 million Revolving
Credit Facility ("new revolver"), which contains a $10.0 million sub-limit for
the issuance of commercial or standby letters of credit. The new revolver is
secured by our non-realty assets including cash, accounts and notes receivable,
and inventories. The new revolver requires us to comply with two quarterly
financial covenants. 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 new
revolver vary with our leverage. We are required to pay a commitment fee of
between .125% and .250% per annum on the unused portion of the new revolver
based on our leverage. As of September 30, 2005, we had no balance outstanding
on the new revolver.

Our principal sources of liquidity are our operating cash flow combined with our
working capital of $149.5 million at September 30, 2005 and availability under
the new revolver. Historically we have generated cash from operations sufficient
to meet our capital expenditure and debt service needs, other than for
acquisitions. At September 30, 2005, our current ratio was 5.0:1.

The Company regularly engages in discussions relating to potential acquisitions
and may announce an acquisition transaction at any time.

Operating activities

Net cash flows provided by operating activities for the nine months' ended
September 30, 2005 increased by approximately $9.0 million over the comparable
period in 2004. Higher sales were primarily responsible for the increase in
operating cash flows.

Investing activities

The majority of the current year increase in acquisition of property, plant and
equipment was for the following:

      a. New medical power manufacturing plant in Alden, NY -- $9.0 million; and
      b. New assembly plant in Tijuana, Mexico -- $9.3 million.

In March 2004, we purchased NanoGram for approximately $45.7 million. The most
significant elements of the purchase price allocation were to patented and
unpatented technology and goodwill. The costs allocated to patented and
unpatented technology are being amortized over the remaining estimated useful
life of 11.5 years. The residual amount of the allocation of $35.1 million went
to goodwill, which is not amortized but rather subject to periodic testing as
part of the total IMC reporting unit goodwill impairment testing. NanoGram is
now referred to as our Advanced Research Laboratory. Since the primary function
of this operation is research and development, all costs are appropriately
classified in that category.


                                     - 29 -


On a year-to-date basis short-term investments increased by approximately $5.1
million.

Financing activities

Payments on capital lease obligations and cash from non-qualified stock option
exercises are the primary financing activities for both year-to-date periods
presented.

Capital Structure

At September 30, 2005, our capital structure consisted primarily of $170.0
million of convertible subordinated notes and our 21.6 million shares of common
stock outstanding. We have in excess of $102.0 million in cash, cash equivalents
and short-term investments and are in a position to facilitate future
acquisitions if necessary. 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
2005 is that capital spending will be in the range of $27.0 million to $32.0
million, primarily as a result of the build-out of the Alden Facility ($11.0
million) and the Tijuana Facility ($10.0 million), and normal maintenance
capital expenditures.

Off-Balance Sheet Arrangements

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

Inflation

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

Impact of Recently Issued Accounting Standards

In June 2005 the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards ("SFAS") No. 154, Accounting Changes and Error
Corrections, ("SFAS 154") a replacement of APB Opinion No. 20, Accounting
Changes, and Statement No. 3, Reporting Accounting Changes in Interim Financial
Statements. SFAS 154 changes the requirements for the accounting for and the
reporting of a change in accounting principle. Previously, most voluntary
changes in accounting principles required recognition by recording a cumulative
effect adjustment within net income in the period of change. SFAS 154 requires
retrospective application to prior periods' financial statements, unless it is
impracticable to determine either the specific period effects or the cumulative
effect of the change. SFAS 154 is effective for accounting changes made in


                                     - 30 -


fiscal years beginning after December 15, 2005. We do not expect that adoption
of SFAS No. 154 will have a material effect on our consolidated financial
position, consolidated results of operations, or liquidity.

In March 2005, the FASB issued Interpretation No. 47, "Accounting for
Conditional Asset Retirement Obligations, an interpretation of FASB Statement
No. 143" ("FIN 47"). FIN 47 requires the recognition of a liability for the fair
value of a legally-required conditional asset retirement obligation when
incurred, if the liability's fair value can be reasonably estimated. FIN 47 is
effective for fiscal years ending after December 15, 2005. We do not expect that
adoption of FIN 47 will have a material effect on its consolidated financial
position, consolidated results of operations, or liquidity.

In December 2004, the FASB issued SFAS No. 123 (revised 2004), Share-Based
Payment ("SFAS No. 123(R)"). This statement is a revision of SFAS No. 123,
Accounting for Stock-Based Compensation, and supercedes APB Opinion No. 25,
Accounting for Stock Issued to Employees. This standard requires the Company to
measure the cost of employee services received in exchange for equity awards
based on the grant date fair value of the awards. The cost will be recognized as
compensation expense over the vesting period of the awards.

We anticipate adopting the provisions of SFAS No. 123(R) on January 1, 2006
using the modified prospective method. Accordingly, compensation expense will be
recognized for all newly granted awards and awards modified, repurchased, or
cancelled after January 1, 2006. Compensation cost for the unvested portion of
awards that are outstanding as of January 1, 2006 will be recognized ratably
over the remaining vesting period. The compensation cost for the unvested
portion of awards will be based on the fair value at date of grant as calculated
for our pro forma disclosure under SFAS 123.

We estimate that the effect on net income and earnings per share in the periods
following adoption of SFAS 123(R) will be consistent with the our pro forma
disclosure under SFAS No. 123 included in the notes to our consolidated
financial statements, except that estimated forfeitures will be considered in
the calculation of compensation expense under SFAS 123(R) and will reduce the
expense accordingly. Additionally, the actual effect on net income and earnings
per share will vary depending upon the number of options granted in subsequent
periods compared to prior years.

In November 2004, the FASB issued SFAS No. 151, Inventory Costs, an amendment of
ARB No. 43, Chapter 4 ("SFAS No. 151"). SFAS No. 151 amends the guidance in ARB
No. 43, Chapter 4, "Inventory Pricing," to clarify the accounting for abnormal
amounts of idle facility expense, handling costs and wasted material (spoilage).
Among other provisions, the new rule requires that such items be recognized as
current-period charges, regardless of whether they meet the criterion of "so
abnormal" as stated in ARB No. 43. SFAS No. 151 is effective for fiscal years
beginning after June 15, 2005. We do not expect that adoption of SFAS No. 151
will have a material effect on our consolidated financial position, consolidated
results of operations, or liquidity.


                                     - 31 -


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 and income taxes.

During the three months ended September 30, 2005, we did not change or adopt new
accounting policies that had a material effect on our consolidated financial
condition or results of operations.

Contractual Obligations

During 2004, we commenced the build out of our Alden Facility and our Tijuana
Facility. These facilities will enable the Company to further consolidate its
operations and implement state of the art manufacturing capabilities at both
locations. The total remaining contractual obligation for construction of these
facilities is $3.4 million and will be financed by existing cash, short term
investments, and cash generated from operations.

Litigation

During 2002, a former non-medical customer commenced an action alleging that we
used proprietary information of the customer to develop certain products. We
have meritorious defenses and are vigorously defending the case. No accrual for
an adverse judgment has been made as such outcome is not deemed probable. We
estimate the potential risk of loss at between $0.0 and $1.75 million.

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
         implantable medical device industry;

      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
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, including Exhibit 99.1 thereto, 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 September 30, 2005, we did not have any borrowings outstanding under
our line of credit and thus no interest rate sensitive financial instruments.

ITEM 4. Controls and Procedures.

a. Evaluation of Disclosure Controls and Procedures. During the third quarter of
   2005, 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. These disclosure
   controls and procedures have been designed to ensure 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. Due to the inherent limitations of control systems, not all
   misstatements may be detected. These inherent limitations include the
   realities that judgments in decision-making can be faulty and that breakdowns
   can occur because of simple error or mistake. Additionally, controls can be
   circumvented by the individual acts of some persons, by collusion of two or
   more people, or by management override of the control. Our controls and
   procedures can only provide reasonable, not absolute, assurance that the
   above objectives have been met.

   Based on their evaluation, as of September 30, 2005, our principal executive
   officer and principal financial officer have concluded that our disclosure
   controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under
   the Securities Exchange Act of 1934) are effective to reasonably ensure that
   the information required to be disclosed by us in the reports that we file or
   submit under the Securities Exchange Act of 1934 is recorded, processed,
   summarized and reported within the time periods specified in SEC rules and
   forms.

   We evaluated our disclosure controls and procedures in light of the factors
   that led us to make the restatements reflected in this report. We determined
   that these adjustments were appropriate based on facts and circumstances as
   of September 30, 2005. We believe that our disclosure controls and procedures
   continue to be 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.

PART II -- OTHER INFORMATION

ITEM 1. Legal Proceedings.

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 case. No
accrual for an adverse judgment has been made as such outcome is not deemed
probable. We estimate the potential risk of loss at between $0.0 and $1.75
million.
