PART I
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.

assets by segment as well as sales from external customers and long-lived assets
by geographic area are incorporated by reference to Note 17 - Business Segment
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.



4






The following table sets forth the main categories of battery-powered IMDs and
the principal illness or symptom treated by each device:




Device Principal Illness or Symptom
- ------ ----------------------------

Pacemakers............................................. Abnormally slow heartbeat (Bradycardia)
ICDs................................................... Rapid and irregular heartbeat (Tachycardia)
CRT/CRT-Ds............................................. Congestive heart failure
Neurostimulators....................................... Chronic pain, movement disabilities, epilepsy, obesity or
depression.
Left ventricular assist devices (LVADs)................ Heart failure
Drug pumps............................................. Diabetes or chronic pain


CRM and Neuro markets are expected to experience double-digit growth for the
next three to five years. Increased demand is being driven by the following
factors:

o Advances in medical technology - new therapies will allow physicians
to use IMDs to treat a wider range of heart diseases.

o New, more sophisticated implantable devices - device manufacturers are
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.

COMMERCIAL BATTERY INDUSTRY

Commercial batteries are used in demanding applications such as oil and gas
exploration and production, oceanographic, and aerospace. High performance
batteries and battery packs are used in drilling tools, pipeline inspection
systems, lightening detectors and seismic applications in the oil and gas
markets.

High quality, reliable products that can deliver increased performance in severe
environments are the drivers for demand in the commercial battery industry. It
is expected that applications in new technologies used for reworking existing
wells will increase. Natural gas exploration is increasing at a rapid pace as
natural gas powered power plants increase in number. Pipeline inspection gauge
usage is increasing due to new US legislation. Military and aerospace trends
show increasing demand for reliable power sources, including rechargeable cells.

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.

7





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.

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

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


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


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


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.




24


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


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


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


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.

28


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.


29



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.

------------------------------------------------
Less than 1-3 3-5 More than
CONTRACTUAL OBLIGATIONS Total 1 year years years 5 years
- --------------------------------------------------------------------------------
Long-Term Debt Obligations (a):
Convertible Debentures $ 170,000 $ - $ - $ - $ 170,000
Capital Lease Obligations 1,652 1,000 652 - -
Operating Lease Obligations (b) 11,466 2,350 3,651 2,652 2,813

------------------------------------------------
Total $ 193,169 $ 13,401 $ 4,303 $ 2,652 $ 172,813
================================================

(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.


30



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



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.

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.

39



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 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 17 - Business Segment information
contains an analysis of goodwill by segment.

40



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 17 - 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.

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.

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.

Year Ended December 31,
2004 2003 2002

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,
2004 2003 2002

Net income as reported $ 16,257 $ 23,288 $ 14,361
Stock based employee compensation cost
included in net income as reported $ 2,250 $ 2,311 $ 2,512

Stock-based employee compensation cost
determined using the fair value based method,
net of related tax effects $ 4,635 $ 4,054 $ 2,972
Pro forma net income $ 13,872 $ 21,545 $ 13,901

Net earnings per share:
Basic - as reported $ 0.76 $ 1.10 $ 0.69
Basic - pro forma $ 0.65 $ 1.02 $ 0.66

Diluted - as reported $ 0.75 $ 1.05 $ 0.68
Diluted - pro forma $ 0.66 $ 0.98 $ 0.65

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 9 - 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.

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.

3. ACQUISITIONS

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

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.

50



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.

Capital Lease Obligations

The Company leases assets under non-cancelable lease arrangements. As of
December 31, 2004, future minimum lease payments under capital leases are
as follows:

(In thousands) Amount
-------------- --------

2005 $ 1,031
2006 659

Less imputed interest (38)
--------
Present value of minimum lease payments 1,652
Less current portion (1,000)
--------
Long-term capital lease obligations $ 652
========

The fair-value of the capital leases as of December 31, 2004 was $1.6
million based on interest rates in effect at year-end.

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.

10. 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.

51




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.

12. 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:

Restricted Weighted Average

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.

13. 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.

14. INCOME TAXES

The provision (benefit) for income taxes comprised the following (in
thousands):
Year Ended December 31,

The tax effect of major temporary differences that give rise to the
Company's net deferred tax accounts are as follows (in thousands):

December 31,
2004 2003

Depreciation $ (6,023) $ (4,776)
Contingent interest on convertible notes (7,194) (2,575)
Amortization of intangible assets (12,843) (1,118)
Tax credits 1,996 2,779
Accrued expenses and deferred compensation 2,007 2,226
Inventory valuation 2,138 1,745
Investments 579 565
Net operating loss carryforwards 699 433
Other - 94
--------- --------
Net deferred tax (liability) asset (18,641) (627)
Less valuation allowance (2,766) (565)
--------- --------
Net deferred tax (liability) asset $ (21,407) $ (1,192)
========= ========


As of December 31, 2004, the Company has available $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.

56


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


Year Ended December 31,
2004 2003 2002

Statutory rate 35.0 % 35.0 % 35.0 %
State taxes, net of federal benefit (1.5) 2.0 3.3
Permanent items (7.2) (6.8) -
Federal and state tax credits (3.3) (2.1) (10.7)
State net operating losses (0.9) - -
Valuation allowance 9.3 - 2.7
Other 0.1 2.0 1.2
------ ------ ------
Effective tax rate 31.5 % 30.1 % 31.5 %
====== ====== ======


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.

15. 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.

16. 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.

57


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
Additions to warranty reserve 781
Warranty claims paid (168)
------
Ending balance $ 926
======

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.

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.

58


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 is $10.0
million and will be financed by existing, or internally generated cash.

17. 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 2.

effective 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. 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.

64


In our opinion, management's assessment that the Company maintained 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, the Company
maintained, in all material respects, 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 as of and for the year ended
December 31, 2004 of the Company and our report dated March 15, 2005 expressed
an unqualified opinion on those financial statements and financial statement
schedule.
