ITEM 1.  BUSINESS

OVERVIEW

We are a leading developer and manufacturer of batteries, capacitors,
feedthroughs, enclosures, and other components used in implantable medical
devices ("IMDs") through our Implantable Medical Components ("IMC") business. We
offer technologically advanced, highly reliable and long lasting products for
IMDs and enable our customers to introduce IMDs that are progressively smaller,
longer lasting, more efficient and more functional. We also leverage our core
competencies in technology and manufacturing through our Electrochem 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. We
believe that our proprietary technology, close customer relationships, multiple
product offerings, market leadership and dedication to quality provide us with
competitive advantages and create a barrier to entry for potential market
entrants.

We plan on expanding our business into value-added assembly of products that
incorporate components. With this in mind, we designed and built a state of the
art manufacturing facility in Tijuana Mexico, incorporating two class 100,000
clean rooms, 90,000 square feet of manufacturing space, engineering, metrology
and quality laboratories, and led by a management team with diverse medical
device and contract manufacturing backgrounds. We will be starting operations in
the 2nd quarter of 2005.

Information of the Notes to Consolidated Financial Statements.

IMPLANTABLE MEDICAL DEVICES

An IMD is an instrument that is surgically inserted into the body to provide
diagnosis or therapy. One sector of the IMD market is cardiac rhythm management
("CRM"), which is comprised of devices such as implantable pacemakers,
cardioverter defibrillators ("ICDs"), cardiac resynchronization therapy ("CRT")
devices, and cardiac resynchronization therapy with backup defibrillation
devices ("CRT-D").

Another sector of the IMD market is neurostimulation ("Neuro"), which is
comprised of pacemaker-type devices that stimulate various nerves for the
treatment of various conditions. Beyond pain control, nerve stimulation for the
treatment of movement disabilities such as Parkinson's disease, epilepsy,
migraines, obesity and depression has shown promising results.

          developing new CRM devices and adding new features to existing
          products.

     o    New indications for CRM devices - the patient groups that are eligible
          for CRM devices has increased. Insurance guidelines may allow device
          reimbursements for these expanding patient populations.

     o    Expansion of Neurostimulator applications - therapies expected to
          expand as new therapeutic applications for pulse generators are
          identified.

     o    An aging population - the number of people in the United States that
          are over age 65 is expected to double in the next 30 years.

     o    New indications for other devices - there is an increased use of
          recently developed IMDs.

     o    New performance requirements - government regulators are increasingly
          requiring that IMDs be protected from EMI interference.

     o    Global markets - increased market penetration worldwide.

RESEARCH AND DEVELOPMENT

Our position as a leading developer and manufacturer of components for IMDs and
commercial batteries is largely the result of our long history of technological
innovation. We invest substantial resources in research, development and
engineering. Our scientists, engineers and technicians focus on improving
existing products, expanding the use of our products and developing new
products. In addition to our internal technology and product development
efforts, we at times engage outside research institutions for special projects.

PATENTS AND PROPRIETARY TECHNOLOGY

We rely on a combination of patents, licenses, trade secrets and know-how to
establish and protect our proprietary rights to our technologies and products.
As of December 31, 2004, we have 246 active U.S. patents and 67 active foreign
patents. We also have 129 U.S. and 329 foreign pending patent applications at
various stages of approval. During the past three years, we have received 113
new U.S. patents, of which 43 were received in 2004. Corresponding foreign
patents have been issued or are expected to be issued in the near future. Often,
several patents covering various aspects of the design protect a single product.
We believe this provides broad protection of the inventions employed.

Our active battery patents relate to process improvements and modifications to
the original technology that was developed either by our Company, or others.

As part of the NanoGram acquisition, we purchased 5 patents and the license
agreements for 28 others. This gives us access to a proprietary laser pyrolysis
system for producing nano-sized particles that will be used in our products and
manufacturing processes. In the near future, we intend to incorporate
nano-cathode materials into selected models of our next generation implantable
power sources. We also expect this innovative technology to have broad
applications to development work across other product offerings including
capacitor materials and implantable coatings.

In addition, we are also a party to several license agreements with third
parties pursuant to which we have obtained, on varying terms, the exclusive or
non-exclusive rights to patents held by them. One of these agreements is for the
basic technology used in our wet tantalum capacitors that we license from Evans
Capacitor Company. We have also granted rights in our own patents to others
under license agreements.

It is our policy to require our executive and technical employees, consultants
and other parties to execute confidentiality agreements. These agreements
prohibit disclosure of confidential information to third parties except in
specified circumstances. In the case of employees and consultants, the
agreements generally provide that all confidential information relating to our
business is the exclusive property of our company.

MANUFACTURING AND QUALITY CONTROL

We primarily manufacture small lot sizes, as most customer orders range from a
few hundred to thousands of units. As a result, our ability to remain flexible
is an important factor in maintaining high levels of productivity. Each of our
production teams receives assistance from a manufacturing support team, which
typically consists of representatives from our quality control, engineering,
manufacturing, materials and procurement departments.

Our quality system is based upon an ISO documentation system and is driven by a
master validation plan that requires rigorous testing and validation of all new
processes or process changes that directly impact our products. All of our
existing manufacturing plants are ISO 9001-2000 registered, which requires
compliance with regulations regarding quality systems of product design (where
applicable), supplier control, manufacturing processes and management review.
This certification can only be achieved after completion of an audit conducted
by an independent authority. Our existing manufacturing plants are audited by
the National Standards Authority of Ireland, an independent auditing firm and
notified body that specializes in evaluating quality standards. To maintain
certification, all facilities must be reexamined routinely by our certifying
body.

SALES AND MARKETING

Products from our IMC business are sold directly to our customers. In our EPS
business, we utilize a combination of direct and indirect sales methods,
depending on the particular product. In 2004, approximately 65% of our products
were sold in the United States. Information regarding our sales by geographic
area is set forth at Note 17 of the Notes to the Consolidated Financial
Statements.

The majority of our medical customers contract with us to develop custom
components and assemblies to fit their specific product specifications. As a
result, we have established close working relationships between our internal
program managers and our customers. We market our products and technologies at
industry meetings and trade shows domestically and internationally, including
Heart Rhythm Society's Annual Scientific Sessions, CardioStim, and the American
Society for Artificial Internal Organs.

Internal sales managers support all activity, and involve engineers and
technology professionals in the sales process to address customer requests
appropriately.

We sell our commercial batteries and battery packs either directly to the end
user, directly to manufacturers that incorporate our products into other devices
for resale, or to distributors who sell our products to manufacturers and end
users. Our sales managers are trained to assist our customers in selecting
appropriate battery chemistries and configurations. We market our EPS products
at various technical trade meetings. We also place print advertisements in
relevant trade publications.

Firm backlog orders at December 31, 2004 and 2003, were $89.5 million and $40.4
million, respectively. Most of these orders are expected to be shipped within
one year.

CUSTOMERS

Our medical customers include leading IMD manufacturers such as Guidant, St.
Jude Medical, Medtronic, Biotronik, Cyberonics and the Sorin Group ("Sorin /
ELA"). 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, including Halliburton, Computalog, PII and
Pathfinder.

We have entered into a supply agreement with Guidant pursuant to which Guidant
purchases batteries from us for use in its IMDs. The agreement secures pricing
and volumes for Li Iodine batteries, and establishes pricing at defined volume
levels for Li SVO and CFx batteries. A contract amendment effective August 16,
2004 adds QHR Frontier Cell pricing to the original agreement. The contract
period for the agreement is April 1, 2003 to December 31, 2006 and can be
renewed for additional one-year periods upon mutual agreement.

We entered into an agreement with Guidant during December 2004 pursuant to which
Guidant will purchase a minimum quantity of wet tantalum capacitors at prices
specified in the agreement during 2005. The period of the agreement is January
1, 2005 to December 31, 2005.

We have entered into a supply agreement with St. Jude Medical pursuant to which
St. Jude Medical purchases batteries, wet tantalum capacitors, filtered
feedthroughs, molded components and enclosures under specified price and volume
terms. A contract amendment effective January 1, 2005 extended the contract term
to December 31, 2008 and added QHR high rate, QMR medium rate, and Nano battery
technologies to the Agreement.

We have entered into a supply agreement with Medtronic pursuant to which
Medtronic will purchase implantable device shield sub-assemblies and other
products under specified price and volume terms. The contract term is seven
years, commencing August 2, 2004 and ending August 2, 2011.

SUPPLIERS AND RAW MATERIALS

We purchase certain critical raw materials from a limited number of suppliers
due to the technically challenging requirements of the supplied product and / or
the lengthy process required to qualify these materials with our customers. We
cannot quickly establish additional or replacement suppliers for these materials
because of these requirements. In the past, we have not experienced any
significant interruptions or delays in obtaining these raw materials. We
maintain minimum safety stock levels of critical raw materials.

For other raw material purchases, we utilize competitive pricing methods to
secure supply such as bulk purchases, precious metal pool buys, blanket orders,
and long term contracts. We believe that there are alternative suppliers or
substitute products available for each of the materials we purchase at
competitive prices.

GOVERNMENT REGULATION

Except as described below, our business is not subject to direct governmental
regulation other than the laws and regulations generally applicable to
businesses in the jurisdictions in which we operate. We are subject to federal,
state and local environmental laws and regulations governing the emission,
discharge, use, storage and disposal of hazardous materials and the remediation
of contamination associated with the release of these materials at our
facilities and at off-site disposal locations. Manufacturing and research,


                                       10
<PAGE>

development and engineering activities involve the controlled use of, and our
products contain, small amounts of hazardous materials. Liabilities associated
with hazardous material releases arise principally under the Comprehensive
Environmental Response, Compensation and Liability Act and analogous state laws
which impose strict, joint and several liability on owners and operators of
contaminated facilities and parties that arrange for the off-site disposal of
hazardous materials. We are not aware of any material noncompliance with the
environmental laws currently applicable to our business and we are not subject
to any material claim for liability with respect to contamination at any company
facility or any off-site location. We cannot assure you, however, that we will
not be subject to such environmental liabilities in the future as a result of
historic or current operations.

As a component manufacturer, our medical products are not subject to regulation
by the Food and Drug Administration ("FDA"). However, the FDA and related state
and foreign governmental agencies regulate many of our customers' products as
medical devices. In many cases, the FDA must approve those products prior to
commercialization. We believe that our existing medical manufacturing plants
comply with current Good Manufacturing Practices ("cGMP") as applicable.

We have five Master Files on record with the FDA. Master Files may be used to
provide confidential detailed information about facilities, processes, or
articles used in the manufacturing, processing, packaging, and storing of one or
more medical device components. These submissions may be used by device
manufacturers to support the premarket notification process required by Section
510(k) of the Federal Food Drug & Cosmetic Act. This notification process is
necessary to obtain clearance from the FDA to market a device for human use in
the United States.

RECRUITING AND TRAINING

We invest substantial resources in our recruiting efforts that focus on
supplying quality personnel to support our business objectives. We have
established a number of programs that are designed to challenge and motivate our
employees. All staff is encouraged to be proactive in contributing ideas.
Feedback surveys are used to collect suggestions on ways that our business and
operations can be improved. We further meet our hiring needs through outside
sources as required.

We provide an intensive training program for our new employees that is designed
to educate them on safety, quality, business strategy, corporate culture, and
the methodologies and technical competencies that are required for our business.
Our safety training programs focus on such areas as basic industrial safety
practices and emergency response procedures to deal with any potential fires or
chemical spills. All of our employees are required to participate in a twenty
hour specialized training program that is designed to provide an understanding
of our quality objectives. Supporting our lifelong learning environment, we
offer our employees a tuition reimbursement program and encourage them to
continue their education at accredited colleges and universities. Many of our
professionals attend seminars on topics that are related to our corporate
objectives and strategies. We believe that comprehensive training is necessary
to ensure that our employees have state of the art skills, utilize best
practices, and have a common understanding of work practices.

are "forward-looking statements" within the meaning of Section 27A of the
Securities Act of 1933, as amended, and Section 21E of the Securities Exchange
Act of 1934, as amended. We have based these forward-looking statements on our
current expectations, which are subject to known and unknown risks,
uncertainties and assumptions. They include statements relating to:

     o    future sales, expenses and profitability;

     o    the future development and expected growth of our business and the IMD
          industry;

     o    our ability to execute our business model and our business strategy;

You can identify forward-looking statements by terminology such as "may,"
"will," "should," "could," "expects," "intends," "plans," "anticipates,"
"believes," "estimates," "predicts," "potential" or "continue" or the negative
of these terms or other comparable terminology. These statements are only
predictions. Actual events or results may differ materially from those suggested
by these forward-looking statements. In evaluating these statements and our
prospects generally, you should carefully consider the factors set forth below.
All forward-looking statements attributable to us or persons acting on our
behalf are expressly qualified in their entirety by these cautionary factors and
to others contained throughout this report. We are under no duty to update any
of the forward-looking statements after the date of this report or to conform
these statements to actual results.

Although it is not possible to create a comprehensive list of all factors that

ITEM 3.  LEGAL PROCEEDINGS

We are involved in 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.

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 range of loss is between $0.0 and $1.7 million.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

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
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.


                                       17
<PAGE>

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
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."



                                       18
<PAGE>

         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
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).


                                       19
<PAGE>

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.

                                       based on our estimate of whether, and the extent
                                       to which, additional taxes will be due.  If we
                                       ultimately determine that payment of these amounts
                                       is unnecessary, we reverse the liability and
                                       recognize a tax benefit during the period in which
                                       we determine that the liability is no longer
                                       necessary.  We record an additional charge in our
                                       provision for taxes in the period in which we
                                       determine that the recorded tax liability is less
                                       than we expect the ultimate assessment to be.

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.




                                       24
<PAGE>

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.


                                       25
<PAGE>

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.

                                       26
<PAGE>

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.

                                       27
<PAGE>

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
$5.0 million.

Investing activities

Capital spending of $38.4 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 ($22.1
               million);
          b.   Oracle ERP system ($5.0 million); and
          c.   New assembly plant in Tijuana, Mexico ($4.6 million).

 In comparison, we spent $11.9 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 $35.1 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.

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.

Approximately $9.0 million of short-term investments were converted to cash
during the year.


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 9 - Debt of the Notes to the
     Consolidated Financial Statements in this Form 10-K for additional
     information about our long-term obligations.

(b)  See Note 16 - Commitments and Contingencies of the Notes to the
     Consolidated Financial Statements in this Form 10-K 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 is $10.0
     million and will be financed by existing, or internally generated cash.

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;

                                       31
<PAGE>


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


Board of Directors and Stockholders
Wilson Greatbatch Technologies, Inc.
Clarence, New York

We have audited the accompanying consolidated balance sheets of Wilson
Greatbatch Technologies, Inc. and subsidiaries (the "Company") as of December
31, 2004 and January 2, 2004, and the related consolidated statements 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 Wilson Greatbatch Technologies,
Inc. and subsidiaries 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, present 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 the
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 expressed an unqualified opinion on management's assessment
of the effectiveness of the Company's internal control over financial reporting
and an unqualified opinion on the effectiveness of the Company's internal
control over financial reporting.

                      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.   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.
     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 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 other
     comprehensive income. 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.

     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
     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 it
