         effect of the conversion of our convertible subordinated notes in the
         calculation of diluted earnings per share using the if-converted method
         as long as the effect is dilutive. The impact on the full year 2003 was
         a $0.03 reduction in earnings per share from $1.08 to $1.05. There was
         no impact on the full year 2004. Diluted earnings per share for 2003
         are restated to reflect the adoption of EITF 04-08.

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 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


                                       6


competencies in technology and manufacturing through our Electrochem Power
Solutions ("EPS") business to develop and produce batteries 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 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
Guidant, St. Jude Medical, Medtronic, Biotronik, Cyberonics and the Sorin Group.
A substantial part of our business is conducted with a limited number of
customers. In 2004, Guidant, St. Jude Medical, and Medtronic collectively
accounted for approximately 70% of our total sales. 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 EPS customers are primarily companies involved in oil and gas
exploration, military, oceanography and aerospace.

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.

Our CEO's View
--------------

At the end of 2003 and the beginning of 2004, we gathered the relevant data and
information on which to base our business forecast. Much of what constitutes the
bulk of the forecasting process relates to communications with customers as well
as our knowledge of historic and current industry trends. The forecasting
process is inexact with some significant factors either unknown to us or out of
our control. This was certainly the case in 2004 when the decision and sudden
actions of a significant customer adversely affected our sales and our earnings.
While a few isolated incidents did affect the 2004 results, it is also true that
there were other more systemic contributing factors. Concentration of risk, with
relatively few customers serving vertical markets, increased competition and
price pressures all played a role and these factors are expected to continue
into the future. This overview will detail our reactions to all of these
influences and provide a summary of how we are addressing each one of these
contributing factors.

         Concentration of Risk - We will be launching new products in 2005, and
will also be providing important new services to expand our business with
existing customers. We are also nurturing opportunities to work with new


                                       7


customers on development programs for components for totally new interventional
cardiac rhythm therapies.

         Increased Competition - We have been the premier supplier of CRM device
power in the form of batteries and capacitors. We have expanded that business to
also include components that make up the vast majority of those found in a
typical pacemaker and defibrillator. Device feedthrough components, EMI filters,
hybrid molded header assemblies and enclosures are all part of our product line.
Our current product portfolio offers leading technology in power sources and
tantalum capacitors, and provides the opportunity for "bundling" these products
with our new assembly capabilities to provide "single source solutions."

         Price Pressures - Technology leadership in a vacuum will not ensure
success. Technology, no matter how advanced, must be priced to present the best
value package to the customer. To that end we continue to implement sweeping
changes in our facilities and processes. The execution of our Pre-Production
Quality Assurance process ("PPQA"), with defined stage gates driven by strict
adherence to Six-Sigma criteria ("Six Sigma" is a Motorola trademark), will
speed the new product development process and add significant efficiencies to
mature product production. Six Sigma is a quality methodology for eliminating
defects in any process. The fundamental objective of the Six Sigma methodology
is the implementation of a measurement-based strategy that focuses on process
improvement and variation reduction. Along with these initiatives, we are
excited to be commissioning two new manufacturing facilities that will provide
enhanced capability for cost reduction. As part of our continuing efforts to
improve our cost structure and manufacturing efficiencies, we will be
undertaking two consolidation efforts in 2005. The first will be the
consolidation of our capacitor and medical battery manufacturing operations into
our newly constructed advanced power source manufacturing facility in Alden, NY.
Also, we will be consolidating the work conducted at our Carson City, NV plant
into the newly constructed Tijuana, Mexico value-add assembly facility. We
believe we will then be well positioned to offer "best value" pricing to the
market.

         Foundation for the Future - It is important to recognize that these
processes and initiatives were started over the past few years as part of our
broader strategic plan. They are the drivers at the very core of our strategy,
which is to be the supplier of the highest quality, most technologically
advanced and cost effective solutions for the industries we serve. This will
certainly raise the expectations of a vital and growing industry and at the same
time raise the bar for our competition.

In the near term however, in reaction to the unexpected reduction in sales
during 2004, we began the difficult process of reducing our workforce to align
our costs with our anticipated revenue for the year. It is vital to understand
that this realignment was totally motivated and implemented after careful
consideration on how to best achieve our already established near and long-term
strategic goals. The flip side to the disappointing news is confirmation that
the vast majority of our customers not only met, but actually exceeded our
internal projections for sales growth in 2004.

In 2004 (and continuing into 2005), we witnessed an unprecedented flow of new
products through the pipeline. One near term catalyst for growth is the
introduction of our Q-Series medical batteries. Initially they will be available


                                       8


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, 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).

New products, as well as enhancements to existing products, were a big part of
our story in 2004, and will continue to gain momentum and have positive impact
in 2005 and beyond. In addition, 2004 was witness to still another watershed
event that marks a unique achievement in our corporate history. In 2004 we
entered into an agreement with Medtronic to provide device sub-assembly
services. It allows us to add value beyond our traditional role as a provider of
discrete components, while providing opportunities for cross-selling and
"bundling" products and services. While at present we are working with Medtronic
in this arena and are focused on CRM and neurostimulator assemblies, we feel
confident in and are aggressively pursuing our options for similar agreements
with other customers and products.

Our work with nanotechnology driven products demonstrates real potential for
generating still more "milestone products" serving the CRM device market. The
investment WGT made in acquiring proprietary nanotechnology in 2004 is expected
to provide a springboard for the next major design/manufacturing/performance
revolution in batteries and related products. As the word implies, "nano"
unlocks the promise of smaller size, but just as significant it offers potential
for enhanced product performance and manufacturability. Additionally, nano
applications are not limited to batteries.

Our Critical Accounting Estimates
---------------------------------

The preparation of financial statements in accordance with generally accepted
accounting principles in the United States ("GAAP") requires management to make
estimates and assumptions that affect reported amounts and related disclosures.
The methods, estimates and judgments we use in applying our accounting policies
have a significant impact on the results we report in our financial statements.
Management considers an accounting estimate to be critical if:

     o    It requires assumptions to be made that were uncertain at the time the
          estimate was made; and

     o    Changes in the estimate or different estimates that could have been
          selected could have a material impact on our consolidated results of
          operations, financial position, or cash flows.

Our most critical accounting estimates are described below. We also have other
policies that we consider key accounting policies, such as our policies for
revenue recognition; however, these policies do not meet the definition of
critical accounting estimates, because they do not generally require us to make
estimates or judgments that are difficult or subjective.

FISCAL 2004 COMPARED WITH FISCAL 2003

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 many 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.

Volume accounted for approximately 7% of the 9% decrease in IMC sales, primarily
due to lower demand by a major customer for wet tantalum capacitors. Total sales
to this customer declined by $27.0 million in comparison to 2003. Sales to other
customers increased by 11% over 2003. The balance of the decrease (2%) was
attributable to lower selling prices. We believe that pricing pressures will
continue into the near future. The decrease in volume of batteries and
capacitors was partially offset by increased volume of other IMC products,
primarily coated components. The overall markets for CRM and Neuro are expected
to experience double-digit growth for the next three to five years.

EPS. 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 5% increase in
EPS sales is due to volume, resulting from increased demand in the oil and gas
market both domestically and internationally.

Gross profit

The 120 basis point decrease in gross margin was primarily due to the following
factors:

     a.   Lower IMC selling prices: 200 basis points; and
     b.   Increased period costs resulting from excess capacity at our wet
          tantalum capacitor manufacturing plant: 100 basis points.
     c.   Savings instituted during the year: (180) basis points, primarily
          scrap reductions.

SG&A expenses

The realignment of management resources resulted in a $3.4 million reduction in
allocated costs to SG&A. Expenses also decreased as a result of cost savings
initiatives instituted mid-year including incentive compensation reductions of
approximately $1.0 million. These savings were partially offset by costs of
approximately $1.0 million associated with Sarbanes-Oxley compliance. The
remaining $0.3 million of expenses were comprised of individually insignificant
items.

                                       13


RD&E expenses

Expenses prior to reimbursements increased by $4.4 million. The main causes of
this increase include additional costs related to the Chief Technology Officer
position ($.9 million), additional development project expenses ($1.3 million)
and the balance was primarily due to the acquisition of NanoGram in March 2004.
These costs were offset by an increase in development efforts for projects where
the company is reimbursed for achieving certain development milestones. The
increase in reimbursements amounted to approximately $3.0 million. We expect to
maintain our spending on RD&E at a level that will support the new technologies
demanded by the customers we serve.

Amortization expense

The increase primarily reflects the impact of the additional intangible
amortization resulting from the NanoGram acquisition. The amortization of the
NanoGram intangibles amounts to approximately $1.1 million in 2004. There was
also a $0.2 million reduction in expense as certain definite lived intangibles
were fully amortized during 2003.

Other operating expense

The 2004 amount comprised the following:
     a.   $2.0 million associated with patents acquired in the second quarter.
          These patents cover how capacitors are used in an ICD. Although
          management believes the patents could have been successfully
          challenged in court proceedings, a decision was made to acquire the
          patents and remove this as a potential obstacle for existing customers
          to more fully adopt wet tantalum technology and for potential
          customers to initially adopt the technology;
     b.   $0.8 million related to severance cost from a 7% mid-year reduction in
          workforce;
     c.   $0.9 million related to costs associated with the start-up of Tijuana
          facility; and
     d.   $0.8 million primarily related to various asset disposals.

Interest expense and interest income

Interest expense increased due to the addition of $90.0 million in
interest-bearing debt in May of 2003 resulting from the issuance of the
convertible subordinated notes.

Interest income increased as the issuance of the convertible subordinated notes
provided additional funds that are being invested on a short-term basis.

Provision for income taxes

Our effective tax rate increased primarily due to the recording of a valuation
allowance against certain New York State deferred tax assets. Based on
managements' review, after considering both the positive and negative support,
it was determined that certain tax assets primarily investment tax credits and
employees incentive credits were not considered to be more likely than not to be
realized. The tax provision increase related to the valuation allowance was $2.2
million.

                                       14


Our effective tax rate is below the United States statutory rate primarily as a
result of federal and state tax credits (3.3%), and the Extraterritorial Income
Exclusion ("ETI") for 2004 of (4.2%). The American Jobs Creation Act of 2004
(P.L. 108-357) ("the Act") signed into law on October 22, 2004 repeals the ETI
after December 31, 2004, and creates new tax incentives for a broad spectrum of
taxpayers. We have not completed a full assessment on how this law change will
impact the Company due to the potential changes in our manufacturing locations.

FISCAL 2003 COMPARED WITH FISCAL 2002

The increase in total sales for 2003 included a full year of sales of Globe,
which we acquired in July 2002. The Globe acquisition added $14.0 million, $3.7
million, and $1.8 million to sales, gross profit, and operating expenses
respectively in 2003 compared to 2002.

Sales

IMC. The sales growth for IMC was led by sales of ICD batteries reflecting the
strength of this market. In addition, capacitor and components sales increased
substantially over last year. Substantially all of the sales changes during 2003
were attributable to volume and sales mix. Looking at our overall sales mix, CRM
product sales increased over 2002 and represented 83% of our overall product
mix, up from 80% in 2002.

EPS. Commercial sales increased modestly from a slight rise in volume of orders
from oil and gas customers.

Gross profit

The following factors contributed to an approximately a 310 basis point decline
in the gross margin between 2003 and 2002:

     a.   Consolidation of EPS plants: 50 basis points;
     b.   Start-up costs from lean manufacturing: 50 basis points;
     c.   Inclusion of enclosure products: 100 basis points;
     d.   Hiring of new plant management personnel: 40 basis points; and
     e.   Changes in selling prices for certain medical components: 70 basis
          points.

SG&A expenses

Expenses increased in absolute dollars, but declined as a percent of sales due
to improved operating leverage. The $6.0 million increase in SG&A was comprised
of the following factors:

     a.   Incentive compensation and profit sharing expense: $1.0 million;
     b.   Incremental senior management related expenses: $2.0 million;
     c.   Corporate spending for information technology: $2.0 million; and
     d.   All other SG&A comprised of individually insignificant items: $1.0
          million.

                                       15


RD&E expenses

Expenses increased in absolute dollars, but decreased as a percent of sales as
sales growth outpaced spending. The increase in RD&E was comprised primarily of
the $1.8 million of expenses for the development of our QHR high rate battery
product.

Amortization expense

The reduction in intangible amortization reflects the impact of the sale of
certain intangible assets of the ceramic capacitor product line that was part of
the Sierra-KD components acquisition in 2003. In addition, one of the patent
licenses for wet tantalum capacitors was fully amortized during 2002.

Other operating expense

The 2003 amount is primarily attributable to the write-down of a manufacturing
facility that became available for sale as the result of a decision to purchase
an additional manufacturing facility in New York.

Interest expense and interest income

Interest expense was lower and interest income was higher primarily due to the
issuance of the $170.0 million convertible subordinated notes in May 2003. These
securities allowed for the outstanding line of credit to be fully replaced at a
lower rate of interest and additional funds to be invested on a short-term
basis.

Provision for income taxes

Our effective tax rate declined primarily as a result of increased research and
development credits, as well as the benefits of state tax planning strategies.
The impact of the lower effective tax rate during 2003 was approximately $0.5
million.

The ETI provided approximately $1.0 million of tax benefit in 2003.

Liquidity and Capital Resources

Our principal sources of liquidity are our operating cash flow combined with our
working capital of $134.4 million at December 31, 2004 and our unused $20
million credit line with our lending syndicate. Historically we have generated
cash from operations sufficient to meet our capital expenditure and debt service
needs, other than for acquisitions. At December 31, 2004, our current ratio was
5.8:1, so short-term liquidity is not a concern to management at this time.

The Company regularly engages in discussions relating to potential acquisitions
and may announce an acquisition transaction at any time. However, no active
negotiations are presently being conducted.

                                       16


Operating activities

In all years presented significant positive cash flows from operating activities
were achieved. Net cash provided by operating activities exceeded the
combination of net income, depreciation and amortization due to the favorable
cash flow impact of deferred taxes. Over the three-year period, changes in
operating assets and liabilities amounted to a net use of cash of approximately
$6.4 million.

Investing activities

Capital spending of $36.7 million in 2004 was significantly higher than
historical expenditure levels. The majority of the current year spending was for
the following:

     a.   New medical power manufacturing plant in Alden, NY ($20.4 million);
     b.   Oracle ERP system ($5.0 million); and
     c.   New assembly plant in Tijuana, Mexico ($4.6 million).

In comparison, we spent $12.5 million in 2003, which was primarily related
to normal maintenance capital.

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. NanoGram has a strong intellectual property
position around the laser pyrolysis process and accordingly a significant
allocation was made to these assets. The cost will be amortized over the
remaining estimated useful life of 11.5 years. For 2004 the amortization expense
was approximately $0.1 million per month. The residual amount of the allocation
of $33.4 million went to goodwill, which is not amortized but rather subject to
periodic testing for impairment. Pursuant to the valuation we obtained, the
status of the NanoGram technology was sufficiently advanced such that technical
feasibility requirements were met at the acquisition date; consequently, no
in-process R&D charge was recorded. The Company determined that it could utilize
$5.0 of gross carryforward net operating losses that were acquired as part of
the acquisition but were not recorded on the opening balance sheet. The
Company's consolidated balance sheet has been restated to reflect the additional
$1.7 million deferred tax asset.

NanoGram was a materials research and development company focused on developing
nanoscale materials for use in various battery and potentially other medical
device applications. The primary purpose of this acquisition is to provide us
with additional intellectual property as well as additional research and
development capabilities. 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. No sales
revenue was attributable to this acquisition in 2004.

In 2002, approximately $47.1 million was spent related to the acquisition of
Globe. Globe was a manufacturer of precision titanium enclosures for IMDs. Globe
was acquired to further broaden our product offerings to include enclosures.

                                       17


Approximately $50.0 million of short-term investments were converted to cash
during the year, net of purchases.

Financing activities

During 2003, we successfully completed a $170.0 million convertible subordinated
notes offering. The proceeds of this offering were utilized to repay $85.0
million in long-term debt that was previously outstanding.

Capital Structure

At December 31, 2004, our capital structure consisted primarily of $170.0
million of convertible subordinated notes and our 21.4 million shares of common
stock outstanding. We have in excess of $92.0 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 and the
average daily trading volume of our common stock has also increased;
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. The current expectation for
2005 is that capital spending is expected to be in the range of $30.0 million to
$35.0 million, primarily due to the build-out of the advanced manufacturing
facility ($11.0 million), our value-add assembly plant ($10.0 million), and
normal maintenance capital expenditures.

Off-Balance Sheet Arrangements

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

Litigation

We are a party to various legal actions arising in the normal course of
business. While we do not believe that the ultimate resolution of any such
pending activities will have a material adverse effect on our 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.

Contractual Obligations
 
The following table summarizes our significant contractual obligations at
December 31, 2004, and the effect such obligations are expected to have on our
liquidity and cash flows in future periods.

     (a)  The current portion of these liabilities is included. Amounts do not
          include imputed interest. The annual interest expense on the
          convertible debentures is 2.25%, or $3.8 million. See Note 10 - Debt
          of the Notes to the Consolidated Financial Statements in this Form
          10-K/A for additional information about our long-term obligations.
     (b)  See Note 17 - Commitments and Contingencies of the Notes to the
          Consolidated Financial Statements in this Form 10-K/A for additional
          information about our operating lease obligations.
     (c)  Purchase orders or contracts for the purchase of raw materials and
          other goods and services are not included in the table above. For the
          purposes of this table, 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. We do not have significant
          agreements for the purchase of raw materials or other goods specifying
          minimum quantities or set prices that exceed our expected requirements
          in the short-term. 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. 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 contractual
          obligations for construction of these facilities are $10.0 million and
          will be financed by existing, or internally generated cash.

                                       19


Inflation

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

Impact of Recently Issued Accounting Standards

In December 2004, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 123 (revised 2004),
Share-Based Payment (SFAS No. 123(R). This statement is a revision of SFAS 123,
Accounting for Stock-Based Compensation, and supercedes APB Opinion No. 25,
Accounting for Stock Issued to Employees. SFAS 123(R) requires the measurement
of the cost of employee services received in exchange for an award of equity
instruments based on the grant-date fair value of the award. The cost will be
recognized over the period during which an employee is required to provide
service in exchange for the award, or over the period that a performance measure
is expected to be met. We will adopt SFAS 123(R) on July 2, 2005, requiring
compensation cost to be recorded as expense for the portion of the outstanding
unvested awards, based on the grant-date fair value of those awards calculated
using the Black-Scholes option pricing model currently used under SFAS 123 for
proforma disclosures. Based on unvested options currently outstanding, the
effect of adopting SFAS 123(R) will reduce our net income by approximately $1.4
million in the second half of 2005.
        
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 its consolidated
financial position, consolidated results of operations, or liquidity.

Subsequent Events

On February 23, 2005 we announced our intent to consolidate our 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. We will also
consolidate 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. We expect to incur this additional expense over
the next four fiscal quarters. The major categories of costs to be incurred,
which will primarily be cash expenditures, include the following:

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

                                       20


     o    Training - $0.6 to $0.7 million;
     o    Moving and facility closures - $0.9 million to $1.0 million; and
     o    Infrastructure - $0.5 to $0.6 million

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

The total estimated cost for this facility consolidation plan is anticipated to
be between $4.5 million and $5.4 million. We expect to incur this additional
cost over the next four fiscal quarters. The major categories of costs to be
incurred include the following:

     o    Costs related to the shut-down 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 move and consolidation of work into Tijuana:
          a.   Production inefficiencies and revalidation - $0.4 to $0.5
               million;
          b.   Relocation and moving expenses - $0.3 to $0.5 million;
          c.   Personnel costs (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 future cash expenditures, except
accelerated depreciation. 

ITEM 7A.  Quantitative and Qualitative Disclosures About Market Risk.

Under our existing line of credit any borrowings bear interest at fluctuating
market rates. At December 31, 2004, we did not have any borrowings outstanding
under our line of credit and thus no interest rate sensitive financial
instruments.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of
Greatbatch, Inc. (formerly named Wilson Greatbatch Technologies, Inc.)
Clarence, NY

We have audited the accompanying consolidated balance sheet of Greatbatch, Inc.,
formerly named Wilson Greatbatch Technologies, Inc., and subsidiaries (the
"Company") as of December 31, 2004 and January 2, 2004, and the related
consolidated statement of operations, stockholders' equity, and cash flows for
each of the three years in the period ended December 31, 2004. Our audits also
included the financial statement schedule listed in the Index at Item 15(a) (2).
These financial statements and financial statement schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on the financial statements and financial statement schedule based on
our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of the Company as of December 31, 2004
and January 2, 2004, and the results of their operations and their cash flows
for each of the three years in the period ended December 31, 2004, in conformity
with accounting principles generally accepted in the United States of America.
Also, in our opinion, such financial statement schedule, when considered in
relation to the basic consolidated financial statements taken as a whole,
presents fairly, in all material respects, the information set forth therein. 

We have also audited, in accordance with the standards of the Public
Company Accounting Oversight Board (United States), the effectiveness of the
Company's internal control over financial reporting as of December 31, 2004,
based on criteria established in Internal Control--Integrated Framework issued
by the Committee of Sponsoring Organizations of the Treadway Commission and our
report dated March 15, 2005 (December 16, 2005 as to the effect of the material
weakness described in Management's Report on Internal Control Over Financial
Reporting (as revised)) expresses an unqualified opinion on management's
assessment of the effectiveness of the Company's internal control over financial
reporting and an adverse opinion on the effectiveness of the Company's internal
control over financial reporting.

As discussed in Note 2, the accompanying consolidated financial statements have
been restated.

                      WILSON GREATBATCH TECHNOLOGIES, INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
--------------------------------------------------------------------------------


1.   DESCRIPTION OF BUSINESS

     The Company - The consolidated financial statements include the accounts of
     Wilson Greatbatch Technologies, Inc. and its wholly owned subsidiaries
     (collectively, the "Company"). All significant intercompany balances and
     transactions have been eliminated in consolidation.

     Nature of Operations - The Company operates in two reportable
     segments-Implantable Medical Components ("IMC") and Electrochem Power
     Solutions ("EPS"). The IMC segment designs and manufactures batteries,
     capacitors, filtered feedthroughs, engineered components and enclosures
     used in IMDs. The EPS segment designs and manufactures high performance
     batteries and battery packs for use in oil and gas exploration,
     oceanographic equipment and aerospace.

2.   RESTATEMENTS

     Subsequent to the original filing of the Company's 2004 Form 10-K, the
     Company concluded that its consolidated financial statements should be
     restated 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 Statement of
     Financial Accounting Standard (SFAS) No. 95, Statement of Cash Flows,
     requires reclassification to short-term investments. The consolidated
     balance sheets as of December 31, 2004 and 2003, and consolidated
     statements of cash flows for the years ended December 31, 2004, and 2003,
     have 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.

     The Company has also restated its consolidated statement of cash flows for
     the years ended December 31, 2004, 2003 and 2002 to reflect the impact of
     changes in accounts payable related to the acquisition of property, plant
     and equipment as a non-cash item as required under SFAS No. 95.

     In addition, 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 Devices Corporation in
     2004. The recording of the deferred tax asset decreased long-term deferred
     income tax liabilities and correspondingly decreased goodwill.


                                       29


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

3.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Financial Statement Year End - The Company utilizes a fifty-two,
     fifty-three week fiscal year ending on the Friday nearest December 31st.
     Fiscal 2004, 2003, and 2002 ended on December 31, 2004, January 2, 2004 and
     January 3, 2003. For clarity of presentation, the Company describes all
     periods as if the year-end is December 31st. Fiscal 2002 included 53 weeks.

     Cash and Cash Equivalents - Cash and cash equivalents consist of cash and
     highly liquid, short-term investments with maturities at the time of
     purchase of three months or less.

     Short-term Investments - Short-term investments are comprised of municipal
     bonds acquired with maturities that exceed three months and are less than
     one year at the time of acquisition, auction rate securities and equity
     securities classified as available-for-sale. Available-for-sale securities
     are carried at fair value with the unrealized gain or loss, net of tax,
     reported in accumulated other comprehensive income as a separate component
     of stockholder's equity. Realized gains and losses and investment income
     are included in current earnings. Due to the short term nature of the
     interest rate resets, the fair market value of the auction rate securities
     approximates their recorded value. Securities that the Company has the
     ability and positive intent to hold to maturity are accounted for as
     held-to-maturity securities and are carried at amortized cost. The cost of
     securities sold is based on the specific identification method. Unrealized
     losses considered to be other than temporary during the period are
     recognized in current earnings.

                                       31


     Fair Value of Financial Instruments - The carrying amount of financial
     instruments, including cash and cash equivalents, trade receivables and
     accounts payable, approximated their fair value as of December 31, 2004 and
     2003 because of the relatively short maturity of these instruments.

     Inventories - Inventories are stated at the lower of cost, determined using
     the first-in, first-out method, or market.

     Assets Available for Sale - Assets available for sale are accounted for at
     the lower of the carrying amount or each asset's estimated fair value less
     costs to sell. Fair value is determined at prevailing market conditions or
     appraisals as needed. At December 31, 2003, the Company classified its
     Amherst, NY facility as held for sale. The Company recorded impairment for
     $0.06 million for the year ended December 31, 2004. The Company continues
     to pursue disposition of its held for sale asset, however there can be no
     assurance if or when a sale will be completed or whether such sale will be
     completed on terms that will enable the Company to realize the full
     carrying value of the asset.

     Property, Plant and Equipment - Property, plant and equipment is carried at
     cost. Depreciation is computed primarily by the straight-line method over
     the estimated useful lives of the assets, which are as follows: buildings
     and building improvements 7-40 years; machinery and equipment 3-10 years;
     office equipment 3-10 years; and leasehold improvements over the remaining
     lives of the improvements or the lease term, if less.

     The cost of repairs and maintenance is charged to expense as incurred;
     renewals and betterments are capitalized. Upon retirement or sale of an
     asset, its cost and related accumulated depreciation or amortization are
     removed from the accounts and any gain or loss is recorded in income or
     expense.

     Intangible Assets - Acquired intangible assets apart from goodwill and
     trademark and names consist primarily of patented and unpatented
     technology. The Company continues to amortize its definite-lived assets on
     a straight-line basis over their estimated useful lives as follows:
     patented technology, 8-17 years; unpatented technology, 5-15 years; and
     other intangible assets, 3-10 years.

     Impairment of Long-lived Assets - The Company assesses the impairment of
     long-lived assets when events or changes in circumstances indicate that the
     carrying value of the assets may not be recoverable. Factors that are
     considered in deciding when to perform an impairment review include
     significant under-performance of a business or product line in relation to
     expectations, significant negative industry or economic trends, and
     significant changes or planned changes in the use of the assets.
     Recoverability potential is measured by comparing the carrying amount of
     the asset to the related total future undiscounted cash flows. If an
     asset's carrying value is not recoverable through related cash flows, the
     asset is considered to be impaired. Impairment is measured by comparing the
     asset's carrying amount to its fair value, based on the best information
     available, including market prices or discounted cash flow analysis. When
     it is determined that useful lives of assets are shorter than originally


                                       32


     estimated, and there are sufficient cash flows to support the carrying
     value of the assets, the rate of depreciation is accelerated in order to
     fully depreciate the assets over their new shorter useful lives. There was
     no impairment of long-lived assets in 2002, 2003 or 2004.

     Goodwill - Goodwill and trademark and names are not amortized but are
     periodically tested for impairment.

     The Company assesses goodwill for impairment by comparing the fair value of
     the reporting units to their carrying amounts on an annual basis, or more
     frequently if certain events occur or circumstances change, to determine if
     there is potential impairment. If the fair value of a reporting unit is
     less than its carrying value, an impairment loss is recorded to the extent
     that the implied fair value of the goodwill within the reporting unit is
     less than its carrying value. Fair values for goodwill are determined based
     on discounted cash flows, market multiples or appraised values as
     appropriate. The Company has determined that, based on the goodwill
     impairment test, no impairment of goodwill and other indefinite-lived
     intangible assets has occurred. Note 18 - Business Segment information
     contains an analysis of goodwill by segment.

     Concentration of Credit Risk - Financial instruments that potentially
     subject the Company to concentration of credit risk consist principally of
     trade receivables. A significant portion of the Company's sales are to
     three customers, all in the medical device industry, and, as such, the
     Company is directly affected by the condition of those customers and that
     industry. However, the credit risk associated with trade receivables is
     minimal due to the Company's stable customer base. The Company maintains
     cash deposits with major banks, which from time to time may exceed
     federally insured limits. Note 18 - Business Segment information contains
     an analysis of sales and accounts receivable for the Company's significant
     customers.

     Allowance for Doubtful Accounts - The Company provides credit, in the
     normal course of business, to its customers. The Company also maintains an
     allowance for doubtful customer accounts and charges actual losses against
     this allowance when incurred.

     Income Taxes - The Company provides for income taxes using the liability
     method whereby deferred tax liabilities and assets are recognized for
     changes in deferred tax assets and liabilities determined based upon the
     changes in differences between the basis of assets and liabilities for
     financial reporting purposes and the basis of assets and liabilities as
     measured by the enacted tax rates that management estimates will be in
     effect when the differences reverse. A valuation allowance is provided on
     deferred tax assets if it is determined that it is more likely than not
     that the asset will not be realized.

     Revenue Recognition - Revenue from the sale of products is recognized at
     the time product is shipped to customers and title passes. The Company
     allows customers to return defective or damaged products for credit,
     replacement, or exchange. Revenue is recognized as the net amount to be
     received after deducting estimated amounts for product returns and
     allowances. The Company includes shipping and handling fees billed to
     customers in Sales. Shipping and handling costs associated with inbound
     freight are generally recorded in Cost of Goods Sold.

                                       33


     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.

     Research and Development - Research and development costs are expensed as
     incurred.

     Engineering Costs - Engineering expenses are expensed as incurred. Cost
     reimbursements for engineering services from customers for whom the Company
     designs products are recorded as an offset to engineering costs upon
     achieving development milestones specified in the contracts.

     Net research, development and engineering costs are as follows (in
     thousands):

     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 that standard, 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.

     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 years presented and, as such, the
     impact is not necessarily indicative of the effects on reported net income
     of future years.

     The Company's net income and earnings per share as if the fair value based
     method had been applied to all outstanding and unvested awards in each year
     is as follows (in thousands except per share data): 

                                                  Year Ended December 31,

     Net earnings per share:

       Diluted - as reported                                   $  0.75      $  1.05        $  0.68

     Earnings Per Share - Basic earnings per share is calculated by dividing net
     income by the weighted average number of shares outstanding during the
     period. Diluted earnings per share is calculated by adjusting for
     common stock equivalents, which consist of stock options and unvested
     restricted stock. Holders of our convertible notes may convert them
     into shares of the Company's common stock under certain circumstances
     (see Note 10 - Debt for a description of our convertible subordinated
     notes).

     The Company adopted Emerging Issues Task Force ("EITF") Issue 04-08, The
     Effect of Contingently Convertible Instruments on Diluted Earnings Per
     Share, in the fourth quarter of 2004. Under EITF 04-08, we must include the
     effect of the conversion of our convertible subordinated notes in the
     calculation of diluted earnings per share using the if-converted method as
     long as the effect is dilutive. For computation of earnings per share under
     conversion conditions, the number of diluted shares outstanding increases
     by the amount of shares that are potentially convertible during that
     period. Also, net income is adjusted for the calculation to add back
     interest expense on the convertible notes as well as deferred financing
     fees amortization recorded during the period.

                                       35

     Comprehensive Income - Comprehensive income includes all changes in
     stockholders' equity during a period except those resulting from
     investments by owners and distribution to owners. For 2003 and 2002, the
     Company's only component of comprehensive income is its net income. For
     2004, the Company's comprehensive income includes net income and unrealized
     losses on available-for-sale securities.

     Use of Estimates - 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 and liabilities and disclosure of contingent
     assets and liabilities at the date of the financial statements and reported
     amounts of sales and expenses during the reporting period. Actual results
     could differ materially from those estimates.

     Recent Accounting Pronouncements -- In December 2004, the Financial
     Accounting Standards Board ("FASB") issued Statement of Financial
     Accounting Standards ("SFAS") No. 123 (revised 2004), Share-Based Payment
     ("SFAS No. 123(R)"). This statement is a revision of SFAS 123, Accounting
     for Stock-Based Compensation, and supercedes APB Opinion No. 25, Accounting
     for Stock Issued to Employees. SFAS 123(R) requires the measurement of the
     cost of employee services received in exchange for an award of equity
     instruments based on the grant-date fair value of the award. The cost will
     be recognized over the period during which an employee is required to
     provide service in exchange for the award, or over the period that a
     performance measure is expected to be met. The Company will adopt SFAS
     123(R) on July 2, 2005, requiring compensation cost to be recorded as
     expense for the portion of the outstanding unvested awards, based on the
     grant-date fair value of those awards calculated using the Black-Scholes
     option pricing model currently used under SFAS 123 for proforma
     disclosures. Based on unvested options currently outstanding, the effect of
     adopting SFAS 123(R) will reduce the Company's net income by approximately
     $1.4 million in the second half of 2005.

     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.


4.   ACQUISITIONS

     During 2002 and 2004, the Company completed two acquisitions as follows:

                                       37


     o    Globe Tool and Manufacturing Company, Inc. ("Globe"), a manufacturer
          of precision titanium enclosures for implantable medical devices.
          Globe was acquired to further broaden our product offering to include
          enclosures.

     o    NanoGram Devices Corporation ("NanoGram"), a materials research and
          development company focused on developing nanoscale materials for
          implantable medical devices. NanoGram was acquired to further broaden
          our materials science expertise. NanoGram utilizes nanomaterials
          synthesis technology in the development of battery and medical device
          applications.

     These acquisitions have been accounted for using the purchase method of
     accounting and accordingly, the results of the operations of these
     acquisitions have been included in the consolidated financial statements
     from the date of acquisition.

    Convertible Subordinated Notes

    In May 2003, the Company completed a private placement of contingent
    convertible subordinated notes totaling $170.0 million, due 2013. In
    November 2003 the Company had a Registration Statement with the Securities
    and Exchange Commission declared effective with respect to these notes and
    the underlying common stock. The notes bear interest at 2.25 percent per
    annum, payable semiannually. 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.

    Holders may convert the notes into shares of the Company's common stock at
    a conversion rate of 24.8219 shares per $1,000 principal amount of notes,
    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 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 principal amount of the notes 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 principal amount of the notes; (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 our subsidiaries.

                                       43



    Concurrent with the issuance of the notes, the Company used approximately
    $72.5 million of the proceeds from this private placement to pay off the
    term loan. Debt issuance expenses totaled $4.5 million and are being
    amortized using the effective yield method over a seven-year term.

    The fair-value of the convertible subordinated notes as of December 31,
    2004 was $154.7 million based on quoted market prices.

    Revolving Line of Credit

    As of December 31, 2004 the Company had no balance outstanding on its $20.0
    million committed revolving line of credit. The revolving line of credit
    continues to be available to the Company for future borrowing and matures
    on July 1, 2005. The revolving line of credit is secured by the Company's
    accounts receivable and inventories and requires the Company to comply with
    various quarterly financial covenants, as defined, related to net earnings
    or loss before interest, taxes, depreciation, and amortization ("EBITDA"),
    and ratios of leverage, interest, fixed charges as they relate to EBITDA
    and funded debt to total capitalization. Interest rates under the revolving
    line of credit vary with the Company's leverage. The Company is required to
    pay a commitment fee of between .50% and .125% per annum on the unused
    portion of the revolving line of credit based on the Company's leverage.

11. EMPLOYEE BENEFIT PLANS

    Savings Plan - The Company sponsors a defined contribution 401(k) plan,
    which covers substantially all of its employees. The plan provides for the
    deferral of employee compensation under Section 401(k) and a Company match.
    Net costs related to this defined contribution plan were approximately $0.9
    million, $0.8 million and $0.7 million in 2004, 2003 and 2002,
    respectively.

    Employee Stock Ownership Plan - The Company sponsored a non-leveraged
    Employee Stock Ownership Plan ("ESOP") and related trust prior to June 29,
    2004. Effective June 29, 2004 the ESOP was merged into the 401(k) plan.
    Under the terms of the amended 401(k) plan document there is an annual
    defined contribution equal to five percent of each employee's eligible
    annual compensation. This contribution is contributed to the 401(k) plan in
    the form of Company stock. Compensation cost recognized for the defined
    contribution in Company stock was approximately $2.7 million, $2.7 million,
    and $2.3 million in 2004, 2003 and 2002, respectively.

    As of December 31, 2004, the 401(k) Plan held 499,430 shares of WGT stock
    and there were 121,743 committed-to-be released shares for the plan, which
    equals the estimated number of shares to settle the liability based on the
    closing market price of the shares at December 31, 2004. The final number
    of shares contributed to the plan was 153,268, computed based on the
    closing market price of the shares on the actual contribution date of
    February 22, 2005, with an adjustment for forfeitures remaining in the
    plan.

    Education Assistance Program - The Company reimburses tuition, textbooks
    and laboratory fees for college or other lifelong learning programs for all
    of its employees. The Company also reimburses college tuition for the
    dependent children of its full-time employees. For certain employees, the
    dependent children benefit vests on a straight-line basis over ten years.
    Minimum academic achievement is required in order to receive reimbursement
    under both programs. Aggregate expenses under the programs were
    approximately $0.8 million, $0.7 million, and $0.6 million in 2004, 2003
    and 2002, respectively.

13.  RESTRICTED STOCK PLAN

     On November 15, 2002, the Company's Board of Directors approved the
     Restricted Stock Plan under which stock awards may be granted to employees.
     The Plan received shareholder approval at the Annual Meeting of
     Stockholders held on May 9, 2003. The number of shares that are reserved
     and may be issued under the plan cannot exceed 200,000. The Compensation
     and Organization Committee of the Company's Board of Directors determines
     the number of shares that may be granted under the plan. Restricted stock
     awards are either time-vested or performance-vested based on the terms of
     each individual award agreement. Time-vested restricted stock vests 50% on
     the first anniversary of the date of the award and 50% on the second
     anniversary of the date of the award. Performance-vested restricted stock
     vests upon the achievement of certain annual diluted earnings per share
     targets by the company, or the seventh anniversary date of the award.

     A summary of the transactions under the Restricted Stock Plan for 2003 and
     2004 follows:

     Unamortized deferred compensation expense with respect to the restricted
     stock grants amounted to $0.8 million and $1.2 million at December 31, 2004
     and 2003, respectively. The deferred compensation is being amortized based
     on the vesting schedules attributable to the underlying restricted stock
     grants. Compensation expense of $0.6 million was recognized during 2004 and
     2003.

14.  OTHER OPERATING EXPENSE

     During second quarter 2004, there were two charges included in other
     operating expense in the Company's Condensed Consolidated Statement of
     Operations.

     Patent acquisition. The Company recorded a $2.0 million pre-tax charge
     associated with the acquisition of certain patents during the quarter. The
     acquired patents cover how wet tantalum capacitors are used in an
     Impantable Cardioverter Defibrillator ("ICD"). Although the Company
     believed that the patents could have been successfully challenged in court
     proceedings prior to the acquisition, a decision was made to acquire the
     patents and remove this as a potential obstacle for existing customers to
     more fully adopt wet tantalum technology and for potential customers to
     initially adopt the technology. The Company had a prior legal opinion that
     in effect concluded the patents were not valid, therefore the Company
     believes it is appropriate to record the $2.0 million acquisition cost in
     accordance with its economic substance as a period expense. This expense is
     included in year to date other operating expense for IMC.

     Severance charges. In response to a reduction in forecasted sales for the
     year, the Company implemented a 7% workforce reduction during June, which
     resulted in a severance charge of $0.8 million during the second quarter.
     The severance charges during the second quarter 2004 were $0.6 million and
     $0.1 million for IMC and EPS, respectively. The remaining $0.1 million
     related to corporate employees and is included in year to date unallocated
     operating expenses. There is no remaining accrued severance as of December
     31, 2004 related to this event as all amounts have been paid.

     As of December 31, 2004, the Company has available $5.0 million of federal
     net operating loss carryforwards that begin expiring in 2022, $1.1 million
     of state net operating loss carryforwards that begin to expire in 2018 and
     $3.1 million of federal and state tax credit carryforwards that begin
     expiring in 2013.

     In assessing the realizability of deferred tax assets, management
     considers, within each taxing jurisdiction, whether it is more likely than
     not that some portion or all of the deferred tax assets will not be
     realized. Management considers the scheduled reversal of deferred tax
     liabilities, projected future taxable income, and tax planning strategies
     in making this assessment. Based on the consideration of the weight of both
     positive and negative evidence, management has determined that it is more
     likely than not that portions of the deferred tax assets remaining at
     December 31, 2004 related to the valuation of an investment and certain
     state investment tax credits and NOLs will not be realized. The valuation
     allowance increase related to the allowance for the state investment tax
     credits and NOLs was $2.2 million and the valuation allowance increase
     related to investments was $0.01 million.

     The provision for income taxes differs in each of the years from the 
     federal statutory rate due to the following:

     In 2004, 2003, and 2002, 43,911, 39,090, and 27,608 shares of common stock,
     respectively, were issued through the exercise of non-qualified stock
     options or through the disqualifying disposition of incentive stock
     options. The total tax benefit to the Company from these transactions,
     which is credited to additional paid-in capital rather than recognized as a
     reduction of income tax expense, was $0.1 million, $0.3 million, and $0.1
     million in 2004, 2003, and 2002, respectively. These tax benefits have also
     been recognized in the consolidated balance sheet as a reduction of current
     income taxes payable.

16.  CAPITAL STOCK

     The authorized capital stock of the Company consists of 100,000,000 shares
     of common stock, $.001 par value per share and 100,000,000 shares of
     preferred stock, $.001 par value per share. There are no preferred shares
     issued or outstanding. There were 21,410,319 and 21,231,121 shares issued
     in 2004 and 2003, respectively. There were 21,405,640 and 21,226,357 shares
     outstanding in 2004 and 2003, respectively.

17.  COMMITMENTS AND CONTINGENCIES

     Litigation - The Company is a party to various legal actions arising in the
     normal course of business. 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 case. No accrual for an adverse judgment has been made as
     such outcome is not deemed probable, the potential risk of loss is between
     $0.0 and $1.7 million.

     License agreements - The Company is a party to various license agreements
     through 2018 for technology that is utilized in certain of its products.
     The most significant of these is an agreement to license the basic
     technology used for wet tantalum capacitors. The initial payment under the
     original agreement was $0.8 million and was fully amortized in 2002. The
     company is required to pay royalties based on agreed upon terms through
     August 2014.

     Expenses related to license agreements were $1.3 million, $1.5 million, and
     $1.4 million, for 2004, 2003, and 2002, respectively.

     Product Warranties - The change in aggregate product warranty liability for
     the year ended December 31, 2004, is as follows (in thousands):

     Beginning balance                                                     $313

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

     Operating Leases - The Company is a party to various operating lease
     agreements for buildings, equipment and software. The Company incurred
     operating lease expense of $2.2 million, $1.7 million, and $0.9 million, in
     2004, 2003 and 2002, respectively.

     If all lease extension options are exercised as expected by the Company,
     minimum future annual operating lease payments are $2.4 million in 2005;
     $1.7 million in 2006; $1.1 million in 2007; $0.8 million in 2008; and $0.9
     million in 2009 and $4.6 million thereafter.

     Workers' Compensation Trust - In Western New York, the Company is a member
     of a group self-insurance trust that provides workers' compensation
     benefits to eligible employees of the Company and other group member
     employers. For locations outside of Western New York, the Company utilizes
     traditional insurance relationships to provide workers' compensation
     benefits. Under the terms of the Trust, the Company makes annual
     contributions to the Trust based on reported salaries paid to the employees
     using a rate based formula. Based on actual experience, the Company could
     receive a refund or be assessed additional contributions. For financial
     statement purposes, no amounts have been recorded for any refund or
     additional assessment since the Trust has not informed the Company of any
     such adjustments. Under the trust agreement, each participating
     organization has joint and several liability for trust obligations if the
     assets of the trust are not sufficient to cover its obligation. The Company
     does not believe that it has any current obligations under the joint and
     several liability.

                                       51



     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. We do not have
     significant agreements for the purchase of raw materials or other goods
     specifying minimum quantities or set prices that exceed our expected
     requirements in the short-term. 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.

     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
     contractual obligations for construction of these facilities are $10.0
     million and will be financed by existing, or internally generated cash.

18.  BUSINESS SEGMENT INFORMATION

     The Company operates its business in two reportable segments: Implantable
     Medical Components ("IMC") and Electrochem Power Solutions ("EPS"). 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. The principal
     medical devices are pacemakers, defibrillators and neurostimulators. The
     EPS segment designs and manufactures high performance batteries 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. In 2002, segment income did not
     include any non-segment specific selling, general and administrative and
     research, development and engineering expenses. The change in 2003 to
     allocate these expenses is not reflected in the 2002 calculation of segment
     income from operations because it is impractical to do so. 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 3.

ITEM 9.  CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND 
         FINANCIAL DISCLOSURE

         None.

ITEM 9A. CONTROLS AND PROCEDURES

 (a) Restatement.

Subsequent to the filing of the Company's original Form 10-K for the fiscal year
ended December 31, 2004, Management concluded that its consolidated financial
statements should be restated to reflect the impact of the following
corrections:

     o Classification of Auction Rate Securities (ARS) - 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
     Statement of Financial Accounting Standard No. 95, Statement of Cash Flows
     (SFAS No. 95), requires reclassification to short-term investments. This
     reclassification impacted the consolidated balance sheets as of December
     31, 2004 and 2003 and consolidated statements of cash flows for the years
     ended December 31, 2004 and 2003. There was no impact on earnings or
     stockholders' equity in any period.

     o Deferred Taxes - A deferred tax asset related to net operating losses
     acquired in the Company's acquisition of NanoGram Devices Corporation in
     2004 was not recorded during the one year time frame allowed to finalize
     the purchase price allocation. The recording of the deferred tax asset
     decreased long-term deferred income tax liabilities and correspondingly
     decreased goodwill in the consolidated balance sheet as of December 31,
     2004. There was no impact on earnings, stockholders' equity, or cash flows
     in any period.

     o Cash Flows Presentation- The Company has also restated its consolidated
     statement of cash flows for the impact of changes in accounts payable
     related to the acquisition of property, plant and equipment which are
     required to be presented as a non-cash activity per SFAS No. 95. This was a
     correction of an error in presentation on the consolidated statements of
     cash flows for the years ended December 31, 2004, 2003 and 2002 only, and
     had no impact on earnings, the balance sheet, or stockholders equity in any
     period.

At the time of the filing of the Company's third quarter 2005 Form 10-Q
(November 9, 2005), Management was preparing restatements to reflect the ARS and
Deferred Tax reclassifications. The combination of these two issues was not
deemed a material weakness. Management discussed these issues with its
independent registered public accounting firm, Deloitte & Touche LLP and with
the Audit Committee of the Board of Directors. After these discussions
Management determined that the Company should correct its previously issued
consolidated financial statements to account for these two restatements. In
light of these restatements, it was also determined that the consolidated
financial statements should no longer be relied upon. This determination was
reported under Item 4.02 in the Form 8-K that the Company filed on November 9,
2005.

                                       56



At the time of the filing of the Company's third quarter 2005 Form 10-Q
(November 9, 2005), the cumulative impact of the Cash Flows Presentation issue
on the September 30, 2005 Statement of Cash Flows was a $38 thousand reduction
in cash flow from operations and a corresponding increase in cash flow from
investing activities. At that time Management also believed that the potential
impact of this issue in other periods was likely immaterial and generally that
this matter would not result in a material misstatement of the Company's
consolidated financial statements. Based on this belief, Management did not
revise its original assessment of the effectiveness of the Company's internal
control over financial reporting at December 31, 2004.

Subsequent to the filing of the third quarter 2005 10-Q, the Company continued
to analyze the impact of the Cash Flow Presentation issue on the Statement of
Cash Flows for the interim and annual periods in 2004 and the March and June
2005 interim periods and discussed this analysis with its independent registered
public accountants. Based on this further analysis, Management determined that
the Cash Flow Presentation issue's impact on the prior period statements of cash
flows would be deemed material. The impact on the statement of cash flows for
the year ended December 31, 2004 was a $1.7 million decrease in operating cash
flows and a corresponding increase in cash flows from investing activities.

Considering this issue to be material, in conjunction with the previously
disclosed restatement, has resulted in Management revising its assessment of the
effectiveness of internal controls over financial reporting as of December 31,
2004 under the guidance issued by the Public Company Accounting Oversight Board.
See Management's Report on Internal Control Over Financial Reporting (as
restated).

(b) Evaluation of Disclosure Controls and Procedures

In connection with the restatements, under the direction of our Chief Executive
Officer and Chief Financial Officer, we reevaluated our disclosure controls and
procedures. It was determined that there was a material weakness in financial
reporting controls that resulted in the restatements described above. Solely as
a result of this material weakness, our Management has revised its earlier
assessment and has now concluded that our disclosure controls and procedures
were not effective as of December 31, 2004.

(c)  Remediation of Material Weakness in Internal Control

As of the date of this filing, we have remediated the material weakness in our
internal controls over financial reporting. The remedial actions included:

     1.   Enhancing the financial reporting process to include the formal review
          of all auction rate securities for proper classification, as well as
          the appropriate cash flow presentation of liabilities related to the
          acquisition of property, plant and equipment.

     2.   Establishing formal quarterly disclosure meetings which will include
          our third party tax advisors to review significant transactions during
          the period as well as to review and discuss new accounting
          presentation and disclosure guidelines. Our independent registered
          public accounting firm, although not part of our control structure,
          will participate in these meetings.

                                       57



     3.   Enhancing our financial reporting practices to include the use of
          multiple third-party financial reporting technical alerts that we
          utilize to evaluate our accounting policies and financial statement
          disclosures.

While we have not completed all of our Sarbanes-Oxley testing for 2005, we
believe that after putting into effect the remedial actions described above, our
Company's internal control over financial reporting is effective, which should
enable us to conclude for purposes of our 2005 assessment that our system of
internal controls over financial reporting are designed and operating
effectively.

As previously reported, there was no change in our internal control over
financial reporting during the quarter ended December 31, 2004, that materially
affected, or is reasonably likely to materially affect, our internal control
over financial reporting. However, subsequent to September 30, 2005, we took the
remedial actions described above regarding the material weakness that existed at
December 31, 2004.

(d) Management's Report on Internal Control Over Financial Reporting (as
restated)

The Management of Greatbatch, Inc. is responsible for establishing and
maintaining adequate internal control over financial reporting for the Company.
With the participation of the Chief Executive Officer and the Chief Financial
Officer, our Management conducted an evaluation of the effectiveness of our
internal control over financial reporting as of December 31, 2004, based on the
framework and criteria established in Internal Control -- Integrated Framework,
issued by the Committee of Sponsoring Organizations of the Treadway Commission.

In the Company's Annual Report on Form 10-K for the year ended December 31,
2004, filed on March 15, 2005, Management concluded that our internal control
over financial reporting was effective as of December 31, 2004. Subsequently,
Management identified three misstatements related to the balance sheet
classification of auction rate securities, the purchase accounting for income
tax attributes of acquired companies, and cash flow presentation of changes in
accounts payable related to the acquisition of property, plant and equipment.
Management determined that these misstatements were the result of a material
weakness in internal control over financial reporting. Specifically, our review
of the financial statements utilizing a presentation and disclosure checklist to
ensure that the financial statements were fairly presented in accordance with
generally accepted accounting principles did not operate effectively as it
relates to the misstatements identified above.

The issues above and the related material weakness has caused us to amend our
Annual Report on Form 10-K for the year ended December 31, 2004, in order to
restate the consolidated financial statements for the years ended December 31,
2004, 2003 and 2002.

Solely as a result of this material weakness, our Management has revised its
earlier assessment and has now concluded that our internal control over
financial reporting was not effective as of December 31, 2004.

The Company's independent registered public accounting firm, Deloitte & Touche
LLP, has issued an audit report on our Management's revised assessment of our
internal control over financial reporting as of December 31, 2004. This audit
report follows.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders
Greatbatch, Inc. (formerly named Wilson Greatbatch Technologies, Inc.)
Clarence, New York

We have audited management's assessment, included in the accompanying
Management's Report on Internal Control Over Financial Reporting (as restated),
that Greatbatch, Inc. (formerly named Wilson Greatbatch Technologies, Inc.) and
subsidiaries (the "Company") did not maintain effective internal control over
financial reporting as of December 31, 2004, because of the effect of the
material weakness identified in management's assessment based on criteria
established in Internal Control--Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission. The Company's management is
responsible for maintaining effective internal control over financial reporting
and for its assessment of the effectiveness of internal control over financial
reporting. Our responsibility is to express an opinion on management's
assessment and an opinion on the effectiveness of the Company's internal control
over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether effective
internal control over financial reporting was maintained in all material
respects. Our audit included obtaining an understanding of internal control over
financial reporting, evaluating management's assessment, testing and evaluating
the design and operating effectiveness of internal control, and performing such
other procedures as we considered necessary in the circumstances. We believe
that our audit provides a reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed by,
or under the supervision of, the company's principal executive and principal
financial officers, or persons performing similar functions, and effected by the
company's board of directors, management, and other personnel to provide
reasonable assurance regarding the reliability of financial reporting and the
preparation of financial statements for external purposes in accordance with
generally accepted accounting principles. A company's internal control over
financial reporting includes those policies and procedures that (1) pertain to
the maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the company; (2)
provide reasonable assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with generally accepted
accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of
the company; and (3) provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use, or disposition of the company's
assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial
reporting, including the possibility of collusion or improper management
override of controls, material misstatements due to error or fraud may not be
prevented or detected on a timely basis. Also, projections of any evaluation of
the effectiveness of the internal control over financial reporting to future
periods are subject to the risk that the controls may become inadequate because
of changes in conditions, or that the degree of compliance with the policies or
procedures may deteriorate.

In our report dated March 15, 2005, we expressed an unqualified opinion on
management's assessment that the Company maintained effective internal control
over financial reporting and an unqualified opinion on the effectiveness of
internal control over financial reporting. As described in the following
paragraph, the Company subsequently identified material misstatements in its
2002, 2003 and 2004 annual financial statements and 2004 and 2005 interim
financial statements, which caused such annual and interim financial statements
to be restated. Management subsequently revised its assessment due to the
identification of a material weakness, described in the following paragraph, in
connection with the financial statement restatement. Accordingly, our opinion on
the effectiveness of the Company's internal control over financial reporting as
of December 31, 2004 expressed herein is different from that expressed in our
previous report.

A material weakness is a significant deficiency, or combination of significant
deficiencies, that results in more than a remote likelihood that a material
misstatement of the annual or interim financial statements will not be prevented
or detected. Management identified three misstatements related to the balance
sheet classification of auction rate securities, the purchase accounting for
income tax attributes of acquired companies, and cash flow presentation of
changes in accounts payable related to the acquisition of property, plant and
equipment. Management determined that these misstatements were the result of a
material weakness in internal control over financial reporting. Specifically,
the review of the financial statements utilizing a presentation and disclosure
checklist to ensure that the financial statements were fairly presented in
accordance with generally accepted accounting principles did not operate
effectively as it relates to the misstatements identified above. This material
weakness does not effect the nature, timing, and extent of audit tests applied
in our audit of the consolidated financial statements of the Company as of and
for the year ended December 31, 2004, and this report also does not effect our
report on such restated consolidated financial statements.

In our opinion, management's revised assessment that the Company did not
maintain effective internal control over financial reporting as of December 31,
2004, is fairly stated, in all material respects, based on the criteria
established in Internal Control--Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission. Also in our opinion,
because of the effect of the material weakness described above on the
achievement of the objectives of the control criteria, the Company has not
maintained effective internal control over financial reporting as of December
31, 2004, based on the criteria established in Internal Control--Integrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway
Commission.

We have also audited, in accordance with the standards of the Public Company
Accounting Oversight Board (United States), the consolidated financial
statements and financial statement schedule of the Company as of and for the
year ended December 31, 2004 and our report dated March 15, 2005, December 16,
2005 as to the effects of the restatement discussed in Note 2, (which report
expressed an unqualified opinion and included an explanatory paragraph relating
to the restatement discussed in Note 2).
