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,
implantable cardioverter defibrillators ("ICDs"), cardiac resynchronization
therapy ("CRT") devices, and cardiac resynchronization therapy with backup
defibrillation devices ("CRT-D").

A new emerging opportunity sector of the IMD market is the neurostimulation
("Neuro") market, 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.


                                       2



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 have 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 Electro Magnetic Interference
          (EMI).

     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, 2005, we have 266 active U.S. patents and 130 active foreign
patents. We also have 138 U.S. and 306 foreign pending patent applications at
various stages of approval. During the past three years, we have received 106
new U.S. patents, of which 20 were received in 2005. 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 six patents and the license
agreements for 24 others. This gives us access to a proprietary technology to
manufacture advanced materials for a broad array of applications. As part of our
technology strategy, we plan to continue development of advanced cathode
materials for our implantable battery product lines. `Nano-SVO' cathode material
is part of this plan, and will eventually become the standard technology broadly
adopted by all SVO battery applications.

In addition, we are also a party to several license agreements with third
parties pursuant under 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, which 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 having access to our confidential information 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.


                                       5



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 ECP
business, we utilize a combination of direct and indirect sales methods,
depending on the particular product. In 2005, approximately 53% 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 contained at Item 8 of this report.

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, the Annual World Congress in
Cardiac Electrophysiology and Cardiac Techniques, known as 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 ECP products
at various technical trade meetings. We also place print advertisements in
relevant trade publications.

Firm backlog orders at December 31, 2005 and 2004, were $92.2 million and $89.5
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 2005, 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 ECP customers are primarily companies involved in oil and gas exploration,
oceanography, aerospace, and defense 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 April 2005 pursuant to which
Guidant will purchase a minimum quantity of wet tantalum capacitors at prices
specified in the agreement. The period of the agreement is April 7, 2005 to
March 31, 2006. We entered into an agreement with Guidant during February 2005
pursuant to which Guidant will purchase a minimum quantity of filtered
feedthroughs at prices specified in the agreement. The period of the agreement
is February 10, 2005 to December 31, 2007.

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. A contract amendment effective January 1, 2006
added molded header assemblies 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. In October 2005, we
entered into a license agreement which grants Medtronic the right to use certain
intellectual property relating to tantalum capacitors. The license is perpetual
and except for our right to make and sell capacitors exclusive to Medtronic.

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


                                       7



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.

COMPETITION

Our existing or potential competitors in our IMC business includes leading IMD
manufacturers, such as Guidant, St. Jude Medical, Medtronic, Sorin / ELA and
Biotronik that currently have vertically integrated operations and may expand
their vertical integration capability in the future. Competitors also include
independent suppliers who typically specialize in one type of component.

Our known non-vertically integrated competitors include the following:

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. Our manufacturing and research,
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 federal
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


                                       9



potential fires or chemical spills. All of our employees are required to
participate in a 20 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.

CAUTIONARY FACTORS THAT MAY AFFECT FUTURE RESULTS

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

     o    future sales, expenses and profitability;

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

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

     o    our ability to identify trends within the IMD, medical component, and
          commercial power source industries and to offer products and services
          that meet the changing needs of those markets;

     o    projected capital expenditures; and

     o    trends in government regulation.

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

Although it is not possible to create a comprehensive list of all factors that
may cause actual results to differ from the results expressed or implied by our
forward-looking statements or that may affect our future results, some of these
factors include the following: dependence upon a limited number of customers,
product obsolescence, inability to market current or future products, pricing
pressure from customers, reliance on third party suppliers for raw materials,
products and subcomponents, fluctuating operating results, inability to maintain
high quality standards for our products, challenges to our intellectual property
rights, product liability claims, inability to successfully consummate and
integrate acquisitions, unsuccessful expansion into new markets, competition,
inability to obtain licenses to key technology, regulatory changes or
consolidation in the healthcare industry, and other risks and uncertainties that
arise from time to time and are described in the Company's periodic filings with
the Securities and Exchange Commission and in Item 1A of this report.


                                       11



ITEM 1A.  RISK FACTORS

Risks Related To Our Business

We depend heavily on a limited number of customers, and if we lose any of them
or they reduce their business with us, we would lose a substantial portion of
our revenues.

A substantial portion of our business is conducted with a limited number of
customers, including Guidant, St. Jude Medical, Medtronic, Sorin / ELA,
Biotronik and Halliburton. In 2005, Guidant, St. Jude Medical, and Medtronic
collectively accounted for approximately 70% of our revenues. Our supply
agreements might not be renewed. Furthermore, many of our supply agreements do
not contain minimum purchase level requirements and therefore there is no
guaranteed source of revenue that we can depend upon under these agreements. The
loss of any large customer or a reduction of business with that customer for any
reason would harm our business, financial condition and results of operations.

If we do not respond to changes in technology, our products may become obsolete
and we may experience a loss of customers and lower revenues.

We sell our products to customers in several industries that are characterized
by rapid technological changes, frequent new product introductions and evolving
industry standards. Without the timely introduction of new products and
enhancements, our products and services will likely become technologically
obsolete over time and we may lose a significant number of our customers. In
addition, other new products introduced by our customers may require fewer of
our batteries or components. We dedicate a significant amount of resources to
the development of our products and technologies and we would be harmed if we
did not meet customer requirements and expectations. Our inability, for
technological or other reasons, to successfully develop and introduce new and
innovative products could result in a loss of customers and lower revenues.

If we are unable to successfully market our current or future products, our
business will be harmed and our revenues and operating results will be reduced.

The market for our medical products has been growing in recent years. If the
market for our products does not grow as rapidly as forecasted by industry
experts, our revenues could be less than expected. In addition, it is difficult
to predict the rate at which the market for our products will grow or at which
new and increased competition will result in market saturation. Slower growth in
the pacemaker, ICD and CRT markets in particular would negatively impact our
revenues. In addition, we face the risk that our products will lose widespread
market acceptance. Our customers may not continue to utilize the products we
offer and a market may not develop for our future products. We may at times
determine that it is not technically or economically feasible for us to continue
to manufacture certain products and we may not be successful in developing or
marketing them. Additionally, new technologies that we develop may not be
rapidly accepted because of industry-specific factors, including the need for
regulatory clearance, entrenched patterns of clinical practice and uncertainty
over third party reimbursement. If this occurs, our business will be harmed and
our revenues and operating results will be negatively affected.


                                       12



We are subject to pricing pressures from customers, which could harm our
operating results.

We have made price reductions to some of our large customers in recent years and
we expect customer pressure for pricing reductions will continue. Further, price
concessions or reductions may cause our operating results to suffer. In
addition, any delay or failure by a large customer to make payments due to us
also could harm our operating results or financial condition.

We rely on third party suppliers for raw materials, key products and
subcomponents and if we are unable to obtain these materials, products and
subcomponents on a timely basis or on terms acceptable to us, our ability to
manufacture products will suffer.

Our business depends on a continuous supply of raw materials. The principal raw
materials used in our business include lithium, iodine, tantalum, platinum,
ruthenium, gallium trichloride, tantalum pellets, vanadium pentoxide, iridium,
and titanium. Raw materials needed for our business are susceptible to
fluctuations due to transportation, government regulations, price controls,
economic climate or other unforeseen circumstances. Increasing global demand for
some of the raw materials we need for our business, including platinum, iridium,
gallium trichloride, tantalum and titanium, has caused the prices of these
materials to increase significantly. In addition, there are a limited number of
worldwide suppliers of several raw materials needed to manufacture our products,
including lithium, gallium trichloride, carbon monofluoride, and tantalum. We
may not be able to continue to procure raw materials critical to our business or
to procure them at acceptable price levels.

We rely on third party manufacturers to supply many of our raw materials.
Manufacturing problems may occur with these and other outside sources, as a
supplier may fail to develop and supply products and subcomponents to us on a
timely basis, or may supply us with products and subcomponents that do not meet
our quality, quantity and cost requirements. If any of these problems occur, we
may be unable to obtain substitute sources of these products and subcomponents
on a timely basis or on terms acceptable to us, which could harm our ability to
manufacture our own products and components profitably or on time. In addition,
to the extent the processes that our suppliers use to manufacture products and
subcomponents are proprietary, we may be unable to obtain comparable
subcomponents from alternative suppliers.

We may never realize the full value of our intangible assets, which represent a
significant portion of our total assets.

At December 31, 2005, we had $215.2 million of intangible assets, representing
42% of our total assets. These intangible assets consist primarily of goodwill,
trademarks, tradenames and patented technology arising from our acquisitions.
Goodwill and other intangible assets with indefinite lives are no longer
amortized, they are tested annually or upon the occurrence of certain events
that indicate that the assets may be impaired. We may not receive the recorded
value for our intangible assets if we sell or liquidate our business or assets.
In addition, the material concentration of intangible assets increases the risk
of a large charge to earnings in the event that the recoverability of these
intangible assets is impaired, and in the event of such a charge to earnings,
the market price of our common stock could be adversely affected. In addition,
intangible assets with definite lives, which represent $60.1 million of our net
intangible


                                       13



assets at December 31, 2005, will continue to be amortized. We incurred total
amortization expenses relating to these intangible assets of $3.8 million in
2005. These expenses will reduce our future earnings or increase our future
losses.

Quality problems with our products could harm our reputation for producing high
quality products, erode our competitive advantage and result in claims against
us.

Our products are held to high quality standards. In the event that our products
fail to meet these standards, our reputation for producing high quality products
could be harmed, which would damage our competitive advantage and could result
in lower revenues. From time to time quality or performance issues have arisen
regarding our products. Product quality or performance issues, however, may
arise in the future that could have a significant adverse impact on us, either
because they harm our reputation for high quality, result in a product liability
or other legal claim against us, harm our reputation with our customers or
result in a decline in our stock price.

If we become subject to product liability claims, our operating results and
financial condition could suffer.

The manufacture and sale of our products expose us to potential product
liability claims and product recalls, including those that may arise from
failure to meet product specifications, misuse or malfunction of, or design
flaws in, our products, or use of our products with components or systems not
manufactured or sold by us. Many of our products are components and function in
interaction with our customers' medical devices. For example, our batteries are
produced to meet various electrical performance, longevity and other
specifications, but the actual performance of those products is dependent on how
they are in fact utilized as part of the customers' devices over the lifetime of
the products. Product performance and device interaction from time to time have
been, and may in the future be, different than expected for a number of reasons.
Consequently, it is possible that customers may experience problems with their
medical devices that could require device recall or other corrective action,
where our batteries met the specification at delivery, and for reasons that are
not related primarily or at all to any failure by our product to perform in
accordance with specifications. It is possible that customers (or patients) may
in the future assert that our products caused or contributed to device failure
where our product was not the primary cause of the device performance issue.
Even if these assertions do not lead to product liability or contract claims,
they could harm our reputation and our customer relationships.

Provisions contained in our agreements with key customers attempting to limit
our damages, including provisions to limit damages to liability for gross
negligence, may not be enforceable in all instances or may otherwise fail to
protect us from liability for damages. Product liability claims or product
recalls, regardless of their ultimate outcome, could require us to spend
significant time and money in litigation or require us to pay significant
damages. The occurrence of product liability claims or product recalls could
adversely affect our operating results and financial condition.

We carry product liability insurance coverage that is limited in scope and
amount. We may not be able to maintain this insurance or to do so at a
reasonable cost or on reasonable terms. This


                                       14



insurance may not be adequate to protect us against a product liability claim
that arises in the future.

Our operating results may fluctuate, which may make it difficult to forecast our
future performance and may result in volatility in our stock price.

Our operating results have fluctuated in the past and are likely to fluctuate
significantly from quarter to quarter due to a variety of factors, including:

     o    the fixed nature of a substantial percentage of our costs, which
          results in our operations being particularly sensitive to fluctuations
          in revenue;

     o    changes in the relative portion of our revenue represented by our
          various products and customers, which could result in reductions in
          our profits if the relative portion of our revenue represented by
          lower margin products increases;

     o    timing of orders placed by our principal customers who account for a
          significant portion of our revenues; and

     o    increased costs of raw materials or supplies.

If we are unable to protect our intellectual property and proprietary rights,
our business could be adversely affected.

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, 2005, we held 266 active U.S. patents. However, the steps we
have taken or will take to protect our proprietary rights may not be adequate to
deter misappropriation of our intellectual property. In addition to seeking
formal patent protection whenever possible, we attempt to protect our
proprietary rights and trade secrets by entering into confidentiality and
non-compete agreements with employees, consultants and third parties with which
we do business. However, these agreements can be breached and, if they are,
there may not be an adequate remedy available to us and we may be unable to
prevent the unauthorized disclosure or use of our technical knowledge, practices
or procedures. If our trade secrets become known, we may lose our competitive
advantages.

In addition, we may not be able to detect unauthorized use of our intellectual
property and take appropriate steps to enforce our rights. If third parties
infringe or misappropriate our patents or other proprietary rights, our business
could be seriously harmed. We may be required to spend significant resources to
monitor our intellectual property rights, we may not be able to detect
infringement of these rights and may lose our competitive advantages associated
with our intellectual property rights before we do so. In addition, competitors
may design around our technology or develop competing technologies that do not
infringe on our proprietary rights.


                                       15



We may be subject to intellectual property claims, which could be costly and
time consuming and could divert our management and key personnel from our
business operations.

In producing our batteries and other components for IMDs, third parties may
claim that we are infringing their intellectual property rights, and we may be
found to have infringed those intellectual property rights. We may be unaware of
intellectual property rights of others that may be used in our technology and
products. In addition, third parties may claim that our patents have been
improperly granted and may seek to invalidate our existing or future patents. If
any claim for invalidation prevailed, the result could be greatly expanded
opportunities for third parties to manufacture and sell products that compete
with our products and our revenues from any related license agreements would
decrease accordingly. We also typically do not receive significant
indemnification from parties which license technology to us against third party
claims of intellectual property infringement. Any litigation or other challenges
regarding our patents or other intellectual property could be costly and time
consuming and could divert our management and key personnel from our business
operations. The complexity of the technology involved in producing our power
sources and other components for IMDs, and the uncertainty of intellectual
property litigation increase these risks. Claims of intellectual property
infringement might also require us to enter into costly royalty or license
agreements. However, we may not be able to obtain royalty or license agreements
on terms acceptable to us, or at all. We also may be subject to significant
damages or injunctions against development and sale of our products.
Infringement claims, even if not substantiated, could result in significant
legal and other costs and may be a distraction to management.

We are dependent upon our senior management team and key personnel and the loss
of any of them could significantly harm us.

Our future performance depends to a significant degree upon the continued
contributions of our senior management team and key technical personnel. Our
products are highly technical in nature. In general, only highly qualified and
trained scientists have the necessary skills to develop our products. The loss
or unavailability to us of any member of our senior management team or a key
technical employee could significantly harm us. We face intense competition for
these professionals from our competitors, our customers and other companies
operating in our industry. To the extent that the services of members of our
senior management team and key technical personnel would be unavailable to us
for any reason, we would be required to hire other personnel to manage and
operate our company and to develop our products and technology. We may not be
able to locate or employ such qualified personnel on acceptable terms.

We may not be able to attract, train and retain a sufficient number of qualified
professionals to maintain and grow our business.

Our success will depend in large part upon our ability to attract, train, retain
and motivate highly skilled employees and management. There is currently
aggressive competition for employees who have experience in technology and
engineering. We compete intensely with other companies to recruit and hire from
this limited pool. The industries in which we compete for


                                       16



employees are characterized by high levels of employee attrition. Although we
believe we offer competitive salaries and benefits, we may have to increase
spending in order to retain personnel.

We may make acquisitions that could subject us to a number of operational risks
and we may not be successful in integrating companies we acquire into our
existing operations.

We have made and expect to make in the future acquisitions that complement our
core competencies in technology and manufacturing to enable us to manufacture
and sell additional products to our existing customers and to expand our
business into related markets. Implementation of our acquisition strategy
entails a number of risks, including:

     o    inaccurate assessments of potential liabilities associated with the
          acquired businesses;

     o    the existence of unknown and/or undisclosed liabilities associated
          with the acquired businesses;

     o    diversion of our management's attention from our core businesses;

     o    potential loss of key employees or customers of the acquired
          businesses;

     o    difficulties in integrating the operations and products of an acquired
          business or in realizing projected efficiencies and cost savings; and

     o    increases in our indebtedness and a limitation in our ability to
          access additional capital when needed.

If we are not successful in making acquisitions to expand and develop our
business, our operating results may suffer.

A component of our strategy is to make acquisitions that complement our core
competencies in technology and manufacturing to enable us to manufacture and
sell additional products to our existing customers and to expand our business
into related markets. Our continued growth will depend on our ability to
identify and acquire companies that complement or enhance our business on
acceptable terms. We may not be able to identify or complete future
acquisitions. Some of the risks that we may encounter include expenses
associated with and difficulties in identifying potential targets, the costs
associated with uncompleted acquisitions, and higher prices for acquired
companies because of competition for attractive acquisition targets. Our failure
to acquire additional companies could cause our operating results to suffer.

We may face competition from our principal medical customers that could harm our
business and we may be unable to compete successfully against new entrants and
established companies with greater resources.

Competition in connection with the manufacturing of products may intensify in
the future. One or more of our customers may undertake additional vertical
integration initiatives and begin to manufacture some or all of their
components.


                                       17



The market for commercial power sources is competitive, fragmented and subject
to rapid technological change. Many other commercial power source suppliers are
larger and have greater financial, operational, personnel, sales, technical and
marketing resources than our company. These and other companies may develop
products that are superior to ours, which could cause our results of operations
to suffer.

Accidents at one of our facilities could delay production and adversely affect
our operations.

Our business involves complex manufacturing processes and hazardous materials
that can be dangerous to our employees. Although we employ safety procedures in
the design and operation of our facilities, there is a risk that an accident or
death could occur in one of our facilities. Any accident, such as a chemical
spill, could result in significant manufacturing delays or claims for damages
resulting from injuries, which would harm our operations and financial
condition. The potential liability resulting from any such accident or death, to
the extent not covered by insurance, could cause our business to suffer. Any
disruption of operations at any of our facilities could harm our business.

We intend to expand into new markets and our proposed expansion plans may not be
successful, which could harm our operating results.

We intend to expand into new markets through the development of new product
applications based on our existing component technologies. These efforts have
required, and will continue to require us to make substantial investments,
including significant research, development and engineering expenditures and
capital expenditures for new, expanded or improved manufacturing facilities. We
may not be able to successfully manage expansion into new markets and products
and these efforts may harm our operating results. Specific risks in connection
with expanding into new markets include the inability to transfer our quality
standards into new products, the failure of customers in new markets to accept
our products and price competition.

Our failure to obtain licenses from third parties for new technologies or the
loss of these licenses could impair our ability to design and manufacture new
products and reduce our revenues.

We occasionally license technologies from third parties rather than depending
exclusively on our own proprietary technology and developments. For example, we
license a capacitor patent from the Evans Capacitor Company. Our ability to
license new technologies from third parties is and will continue to be critical
to our ability to offer new and improved products. We may not be able to
continue to identify new technologies developed by others and even if we are
able to identify new technologies, we may not be able to negotiate licenses on
favorable terms, or at all. Additionally, we could lose rights granted under
licenses for reasons beyond our control. For example, the licensor could lose
patent protection for a number of reasons, including invalidity of the licensed
patent.


                                       18



Risks Related To Our Industries

We and our customers are subject to various political, economic and regulatory
changes in the healthcare industry which could force us to modify how we develop
and price our products.

The healthcare industry is highly regulated and is influenced by changing
political, economic and regulatory factors. Several of our product lines are
subject to international, federal, state and local health and safety, packaging
and product content regulations. In addition, IMDs produced by our medical
customers are subject to regulation by the U.S. Food and Drug Administration and
similar governmental agencies. These regulations govern a wide variety of
product activities from design and development to labeling, manufacturing,
promotion, sales and distribution. Compliance with these regulations may be time
consuming, burdensome and expensive and could negatively affect our customers'
abilities to sell their products, which in turn would adversely affect our
ability to sell our products. This may result in higher than anticipated costs
or lower than anticipated revenues.

These regulations are also complex, change frequently and have tended to become
more stringent over time. Federal and state legislatures have periodically
considered programs to reform or amend the U.S. healthcare system at both the
federal and state levels. In addition, these regulations may contain proposals
to increase governmental involvement in healthcare, lower reimbursement rates or
otherwise change the environment in which healthcare industry participants
operate. We may be required to incur significant expenses to comply with these
regulations or remedy past violations of these regulations. Any failure by our
company to comply with applicable government regulations could also result in
cessation of portions or all of our operations, impositions of fines and
restrictions on our ability to carry on or expand our operations. In addition,
because many of our products are sold into regulated industries, we must comply
with additional regulations in marketing our products.

Our business is subject to environmental regulations that could be costly for
our company to comply with.

Federal, state and local regulations impose various environmental controls on
the manufacturing, transportation, storage, use and disposal of batteries and
hazardous chemicals and other materials used in, and hazardous waste produced
by, the manufacturing of power sources and components. Conditions relating to
our historical operations may require expenditures for clean-up in the future
and changes in environmental laws and regulations may impose costly compliance
requirements on us or otherwise subject us to future liabilities. Additional or
modified regulations relating to the manufacture, transportation, storage, use
and disposal of materials used to manufacture our batteries and components or
restricting disposal of batteries may be imposed. In addition, we cannot predict
the effect that additional or modified regulations may have on us or our
customers.


                                       19



Consolidation in the healthcare industry could result in greater competition and
reduce our medical component revenues and harm our business.

Many healthcare industry companies are consolidating to create new companies
with greater market power. As the healthcare industry consolidates, competition
to provide products and services to industry participants will become more
intense. These industry participants may try to use their market power to
negotiate price concessions or reductions for our products. If we are forced to
reduce our prices because of consolidation in the healthcare industry, our
revenues would decrease and our operating results would suffer.

Our IMC business is indirectly subject to healthcare industry cost containment
measures that could result in reduced sales of our products.

Our healthcare customers rely on third party payors, such as government programs
and private health insurance plans, to reimburse some or all of the cost of the
procedures in which our products are used. The continuing efforts of government,
insurance companies and other payors of healthcare costs to contain or reduce
those costs could lead to patients being unable to obtain approval for payment
from these third party payors. If that occurred, sales of IMDs may decline
significantly, and our customers may reduce or eliminate purchases of our
products. The cost containment measures that healthcare providers are
instituting, both in the United States and internationally, could reduce our
revenues and earnings.

Our non-medical power source revenues are dependent on conditions in the oil and
natural gas industry, which historically have been volatile.

Sales of our commercial products depend to a great extent upon the condition of
the oil and gas industry and, specifically, the exploration and production
expenditures of oil and gas companies. In the past, oil and natural gas prices
have been volatile and the oil and gas exploration and production industry has
been cyclical, and it is likely that oil and natural gas prices will continue to
fluctuate in the future. The current and anticipated prices of oil and natural
gas influence the oil and gas exploration and production business and are
affected by a variety of political and economic factors beyond our control,
including worldwide demand for oil and natural gas, worldwide and domestic
supplies of oil and natural gas, the ability of the Organization of Petroleum
Exporting Countries, or OPEC, to set and maintain production levels and pricing,
the level of production of non-OPEC countries, the price and availability of
alternative fuels, political stability in oil producing regions and the policies
of the various governments regarding exploration and development of their oil
and natural gas reserves. An adverse change in the oil and gas exploration and
production industry or a reduction in the exploration and production
expenditures of oil and gas companies could cause our revenues from commercial
products to suffer.

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 matter.
The potential range of loss is between $0.0 and $1.7 million.

     Technical Corrections, at the beginning of fiscal year 2003. Under SFAS No.
     145, we are no longer allowed to classify debt extinguishments as
     extraordinary items in our consolidated financial statements, subject to
     limited exceptions. Accordingly, amounts previously classified as
     extraordinary related to debt extinguishments in fiscal 2001 have been
     reclassified as components of income before income taxes.

     conversion of our convertible subordinated notes in the calculation of
     diluted earnings per share using the if-converted method as long as the
     effect is dilutive. The impact on the full year 2003 was a $0.03 reduction
     in earnings per share from $1.08 to $1.05. There was no impact on the full
     year 2004. Diluted earnings per share for 2003 are restated to reflect the
     adoption of EITF 04-08.
(7)  The financial information has been amended to reflect the restatements
     described in Note 2. Restatements to the consolidated financial statements
     in Item 8.
(8)  During 2005, we recorded charges in other operating expense related to our
     ongoing cost savings and consolidation efforts. Additional information is
     set forth at Note 14 of the Notes to the Consolidated Financial Statements
     contained at Item 8 of this report.

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 Commercial
Power ("ECP") business to develop and produce batteries and battery packs for
commercial applications that demand high performance and reliability, including
oil and gas exploration, oceanographic equipment and aerospace.

Most of the IMC products that we sell are utilized by customers in cardiac
rhythm management ("CRM") devices. The CRM market comprises devices utilizing
high-rate batteries and capacitors such as implantable cardioverter
defibrillators ("ICDs") and cardiac resynchronization therapy with backup
defibrillation devices ("CRT-D") and devices utilizing low or medium rate
batteries but no capacitors (pacemakers and CRTs). All CRM devices utilize other
components such as enclosures and feedthroughs, and certain CRM devices utilize
electromagnetic interference ("EMI") filtering technology.

Our Customers

Our products are designed to provide reliable, long lasting solutions that meet
the evolving requirements and needs of our customers and the end users of their
products. Our medical customers include leading IMD manufacturers such as
Guidant, St. Jude Medical, Medtronic, Biotronik, Cyberonics and the Sorin Group.
A substantial part of our business is conducted with a limited number of
customers. In 2005, 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

Our CEO's View

We are very pleased with our financial performance in 2005. We achieved sales
growth of 20%, and increased operating cash flow by $43.0 million. 2005 marked a
year of considerable change in the industry. A factor in this year's performance
has been the ability of our team to recognize this change, look for the
opportunities that always accompany any changes and then, most importantly,
capitalize on that new dynamic. We are pleased with our accomplishments and the
commitment to the continued growth for our company, its associates and its
shareholders. 2005 was an event filled year in our markets with significant
merger and acquisition activity and marketplace customer field actions.


                                       26



In the case of Greatbatch, we reacted quickly and decisively and were ultimately
rewarded by our performance. Not all of the change this past year was initiated
externally however, and there is much to report regarding our own "dynamic" news
for 2005. First and foremost, we were pleased to bring two new production
facilities on-line with the opening of Alden, NY and Tijuana, Mexico. The
facility in Alden incorporates state-of-the-art capability for precise and
efficient manufacture of implantable medical batteries and capacitors. This
125,000 square foot plant puts us in position to respond to our customers in a
more timely and effective manner.

We were honored to have Mexico's President, Vicente Fox, as our guest at the
dedication of our new 144,000 square foot facility in Tijuana. At that location
we are, in part, concentrating on an aspect of the implantable device industry
that represents, for us, the opportunity for both growth and diversification. It
is there that we are providing sophisticated assembly services to existing and
new customers both within, and outside, the CRM market in which we're so well
established.

The Alden and Tijuana stories do not end there. Those sites are now, and will
continue to be, critical elements in our strategic facilities consolidation
plan. Capacitor production has been integrated into the Alden facility and the
filtered feedthrough assembly operations have been relocated to the Tijuana
facility. We are also consolidating all of our medical research and development
operations into Clarence, NY. Additionally, feedthrough manufacturing operations
will be transferred to Tijuana by mid-2007. These consolidations not only
provide increased efficiencies and economies of operation, but also provide a
unique synergy between product groups that never before existed with discrete
locations.

With the ICD market expected to grow 20% over the next three to five years and
with the further expansion of our commercial market presence into the
telematics, oceanographic, military and core oil and gas industries, we feel
confident that our consolidation and current manufacturing philosophy lays the
foundation for supporting new and increasing manufacturing demands. In 2005, our
commercial business revenues increased by 21%, resulting from an expansion of
our sales presence in the marketplace. Seismic applications for our products in
the areas of wave and ocean bottom research and exploration, along with military
use in remote sensing and communications technology, are examples of our
expansion beyond our traditional strength in the oil and gas industries. We are
looking ahead to new markets, such as telematics and the possible introduction
of rechargeable battery packs, which offer potential for sustained growth.

2005 marked the first production of the Greatbatch QHR (high rate) battery for
the implantable medical device industry. This new technology further reinforces
the reputation of Greatbatch as innovator, developer and manufacturer of
implantable, medical power sources. At the same time, we are making progress in
the development of a revolutionary high voltage capacitor solution to meet the
demands of the next generation of CRM devices and are expecting release of that
product in 2007. New inductor slab and molded header designs for devices are
also in the development pipeline and offer opportunities for increased growth.

In addition to the aforementioned market opportunities, the neurostimulation
market represents another growth opportunity for Greatbatch. The technology
offers advanced therapy for relief from chronic pain, obesity, Parkinson's
disease, depression, epilepsy, stroke, tremor and other


                                       27



conditions. Because of the diverse conditions for which it provides treatment,
the neurostimulation market could easily rival the CRM market in size over the
long term. Primary batteries are ultimately expected to be the power source of
choice in more than half of the neurostimulation applications. These devices are
similar in technology to pacemakers and we are currently developing our QMR
(medium rate) power source technology to specifically meet the requirements of
these new devices. We believe our QMR battery has some significant and critical
advantages such as high energy in a small package, high power capabilities to
drive advanced telemetry features, MRI enabled and stable discharge
characteristics over life, with availability in proprietary and non-proprietary
designs. We currently anticipate initial deliveries of the QMR technology to
customers in the fourth quarter of 2006.

For the remainder of the neurostimulation market that has a higher power
requirement that cannot be met by primary batteries, the answer lies with
secondary power sources (rechargeable). We are presently investing in advancing
our own rechargeable battery program. We expect that these high power and high
energy cells will be available by the first half of 2007. With power solutions
in position for our neurostimulation customers, we are poised for a logical and
natural entry into selling our complete line of components (feedthroughs,
coatings, enclosures and precision machined parts) to those same customers. Most
of those products are very mature and will require little, if any,
re-engineering to be valuable to neurostimulation manufacturers.

Beyond neurostimulation there is another therapy with which we've been
integrally involved - the intravascular ICD. As with the benefits of traditional
CRM therapies the new technology has been enabled by Greatbatch battery,
capacitor and filtered feedthrough designs and capabilities. We are currently
collaborating with a leader in the field to bring this new device category to
market.

The foundation for the growth in our Company is dependant on successfully
executing on our corporate strategy. This strategy is based on four key
principles:

     1. maintaining our technology leadership;
     2. optimizing our operational capabilities;
     3. delivering customer focused growth; and
     4. pursuing business development opportunities.

Maintaining our technology leadership will require us to maintain a fresh
pipeline of next generation core components, and to transition from supplying
discrete products to providing integrated solutions by bundling our proprietary
technology. Working closely with our customers to understand their product
design changes will be important to minimize the threat of alternative and
replacement technologies.

Optimizing our operational capabilities involves not only successfully executing
on our facility consolidation plan, but is also predicated on maintaining a
robust quality system to ensure product reliability and efficient internal
business practices. In order to maintain a market leadership position, we must
reduce the time to market and design products for manufacturability.


                                       28



In order to deliver customer focused growth, we must understand our customer
needs and design solutions into applications early in the end-product life
cycle. Providing our customers with comprehensive solutions should allow us to
better protect our market share position and reduce competitive threats.

Our biggest risk rests with the heavy concentration of sales with our three
largest customers, which comprise approximately 70% of our total revenues. In
order to establish a platform for growth, we must strengthen our competencies
and broaden the Greatbatch customer base. As part of our growth strategy, we
will continue to look for acquisitions that will allow us to diversify the
customer base while maintaining our focus on proprietary growth products.

In summary, we've maintained our focus despite turbulence in the industry and
actually leveraged those changes to our benefit. We've celebrated our 35 year
anniversary. We are launching important new products that enhance an already
enviable reputation for releasing innovative, high quality, safe and reliable
technologies. We maintain a strong financial position and have in place an
equally strong management team - both of which are essential for our future. All
of these factors are critical in providing stability and growth during changing
times.

Cost savings and consolidation efforts

During 2005, we recorded charges in other operating expense related to our
ongoing cost savings and consolidation efforts. Additional information is set
forth at Note 14 of the Notes to the Consolidated Financial Statements contained
at Item 8 of this report.

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

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

The total cost estimated for these consolidation efforts is anticipated to be
between $3.5 million and $4.0 million. Expenses of $2.8 million were incurred in
2005. Of these, $1.8 million were paid in cash, $0.8 million were for assets
written-off, and $0.2 million remain to be paid. We expect to incur the
remaining expense during the first quarter of 2006.

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


                                       29



The total estimated cost for this facility consolidation plan is anticipated to
be between $5.2 million and $5.5 million, comprised of $3.2 million for the
Carson City Facility shutdown and $2.0 million to $2.3 million for Tijuana
Facility consolidation No. 1. We expect to incur the remaining costs over the
next three fiscal quarters. All categories of costs are considered to be cash
expenditures, except for accelerated depreciation.

Carson City Facility shutdown expenses of $2.9 million were incurred in 2005, of
which $0.2 million were paid in cash, $0.6 million have been recorded as
accelerated depreciation and $2.1 million remain to be paid. Tijuana Facility
consolidation No. 1 expenses of $1.5 million have been incurred and paid year to
date.

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

The total estimated cost for this facility consolidation plan is anticipated to
be between $7.9 million and $8.3 million. We expect to incur this additional
cost over the next 6 quarters. All categories of costs are considered to be
future cash expenditures, except for accelerated depreciation and asset
write-offs.

Columbia Facility and ARL shutdown expenses of $1.1 million have been incurred
year to date, of which $0.4 million have been recorded for assets written-off,
and $0.7 million remain to be paid. Tijuana Facility consolidation plan No. 2
expenses of $0.01 million have been incurred and paid in cash in 2005.

Our Critical Accounting Estimates

The preparation of financial statements in accordance with generally accepted
accounting principles in the United States of America ("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 2005 COMPARED WITH FISCAL 2004

Sales

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

The 2005 results received the benefit of market place customer field actions
surrounding ICD products. However, it is extremely difficult to identify how
much benefit we received during the year. We do not have specific information on
the nature of the orders and can only assume that some percentage of the
increase relates to the ICD marketplace customer field actions.

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

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

The increase in IMC sales of 20% for 2005 was primarily due to increased demand
for ICD batteries, filtered feedthroughs, coated components and medical
enclosures offset by an average 2% reduction in selling prices.

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

The ECP sales increase of 21% for 2005 was driven by the following factors:
First and foremost, we have expanded our commercial sales force. We are
aggressively pursuing new business opportunities and have been successful on
many of these fronts.

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


                                       35



underway in our Canton facility and throughout the Company. Reduced lead times
have allowed us to win customer orders that would normally have gone to other
suppliers.

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

2006 Sales Outlook

We expect 2006 net sales to increase 2% to 10%. We expect IMC sales to increase
by 1% to 10%. This projection takes into consideration the effect of the
marketplace field actions that occurred in 2005 and resulted in incremental
medical sales of $10.0 million to $15.0 million. IMC's primary markets are CRM
and neurostimulation. The CRM market is comprised of two sub-markets - ICD and
pacemaker. In 2006, the ICD market is expected to grow between 15% - 20% and the
pacemaker market growth is expected to be 0% to 4%. The neurostimulation market
is expected to grow by 18% to 20%. Growth in these markets is based on expanding
patient base indicated for device therapy, broader medical reimbursement
coverage, favorable clinical trials and expanding indications for treatment of
various medical conditions.

We expect ECP sales to increase by 6% to 12%. ECP's primary markets are oil and
gas, as well as oceanographic. In 2006, these markets are expected to grow by 6%
and 11%, respectively. Growth in these markets will be driven by the price of
oil, increased requirements for pipeline inspections, and increased monitoring
of wave and ocean bottom research.

Cost of Sales

The 2005 impact on cost of sales as a percentage of sales was primarily due to
the following factors:

                                                                     Year ended
                                                                    December 31,
                                                                        2005

Production efficiencies primarily associated with higher volumes (a)       -3.4%
Excess capacity at wet tantalum capacitor and Tijuana facilities (b)        2.2%
Lower IMC selling prices (c)                                                1.5%
Profit sharing accruals and incentive compensation (d)                      0.3%

                                                                            ----

                                                                            ====

a.   This decrease in cost of sales is primarily due to the fact that as
     production volumes increase, fixed costs such as plant overhead and
     depreciation do not increase at the same rate.
b.   During 2005, two facilities were not being utilized to their full capacity.
     The capacitor facility was initially established to handle higher levels of
     production quantities. The capacitor facility is expected to be fully
     consolidated into the Alden facility by the end of the first quarter 2006.
     This should eliminate the costs associated with the original capacitor


                                       36



     facility. The Tijuana facility is new for 2005 and as a result its floor
     space and infrastructure are considered under utilized at this time. The
     production of feedthroughs (currently being performed in Carson City and
     Columbia) is in the process of being relocated to the Tijuana facility. See
     the "cost savings and consolidation" section for additional information.
c.   Sales prices for Implantable Medical Components are subject to pricing
     agreements with customers. Many times these agreements allow for changes in
     price due to customer specific levels of demand.
d.   Based on several metrics, this year's profit sharing and incentive
     calculations were higher than in 2004.
e.   We incurred incremental warranty costs in 2005 to settle customer claims
     related to the IMC segment.

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

SG&A expenses

The increase in SG&A expenses for 2005 is primarily due to the following factors
(in millions):


                                                                    Year ended

SG&A expenses are expected to increase in 2006 by approximately $3.7 to $4.3
million due to the implementation of SFAS No. 123 (revised 2004), Share-Based
Payment ("SFAS No. 123(R)"). This incremental cost is expected to be partially
offset by savings in other areas. However, the increase in sales and marketing
is expected to continue into the future.

Gross RD&E spending was slightly higher in 2005 compared to 2004. Expenses
increased during 2005 by $2.1 million for increased staffing in RD&E to support
increased research initiatives for IMC. These expenses were offset by the QHR
battery product line moving from the development stage into production ($1.3
million). The gross costs in each year were offset by repayments for development
efforts for projects where the company is reimbursed for achieving certain
development milestones. These reimbursements were 4% lower in 2005 compared to
2004, resulting in the increase in net expense.

Gross RD&E spending is anticipated to increase in 2006 based on the number of
projects currently in development. We estimate that net RD&E costs will be in
the range of 9% to 10% of sales in 2006.

Other operating expense

Other operating expense for 2005 and 2004 comprised the following costs (in

a.   Refer to "Cost savings and consolidation efforts" discussion for disclosure
     related to the timing and level of remaining expenditures for these items
     as of December 31, 2005. In 2004, the severance charge was from a 7%
     mid-year reduction in workforce.


                                       38



b.   The $1.2 million charge was recorded in other operating expenses during the
     second quarter of 2005 for charges associated with the discontinuation of a
     drug pump development agreement, which was transferred back to the customer
     for further development.
c.   This caption includes a $2.8 million write-down of automated cathode
     assembly equipment in 2005. This charge was primarily related to a decision
     not to continue to use some battery production equipment. The manufacturing
     process related to this equipment did not match our overall manufacturing
     strategy. Remaining expenditures in 2005 and 2004 were for asset disposals.
d.   The charge is associated with patents acquired in the second quarter of
     2004. 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.

Other operating expenses for 2006 are expected to be in the range of $10.0
million and $12.5 million primarily related to plant consolidations and asset
dispositions. In the future, other operating expenses are expected to be
substantially reduced after the second quarter of 2007 when the last announced
consolidation effort is anticipated to be completed.

Interest expense and interest income

Interest expense is consistent with prior year, and is primarily related to the
contingent convertible notes. Interest income increased during 2005 in
comparison to 2004 due to higher interest rates and higher cash and short-term
investment balances.

Provision for income taxes

Our effective tax rate is below the United States statutory rate primarily as a
result of federal research and development tax credits and the allowable
Extraterritorial Income Exclusion ("ETI") for 2005. The effective tax rate in
2004 was higher than in 2005 primarily due to the recognition of a valuation
allowance against state investment tax credits that were no longer deemed more
likely than not to be realized.

In accordance with Financial Accounting Standards No. 5, Accounting for
Contingencies, the Company records tax contingencies when the exposure item
becomes probable and reasonably estimable. In an audit during 2005, the Internal
Revenue Service ("IRS") has questioned the amount of the deduction relative to
the interest expense associated with the Convertible Subordinated Notes ("CSN").
A deferred tax liability has been established for the difference between the
amount of interest expense deducted for income taxes and the amount recorded as
expense for book purposes. The amount of the recorded deferred income tax
liability as of December 31, 2005 is approximately $11,428. If the entire
interest expense deduction is disallowed by the IRS, an additional $3.5 million
would be payable, and recorded as an expense. The Company maintains that the
risk of the entire interest expense deduction being disallowed is minimal. If
the amount of interest expense deduction up to the difference between the amount
recorded for books and tax is disallowed, a portion of the deferred income tax
liability would become currently payable. The Company believes that it has
appropriate support for its income tax provision and that the income tax
balances have been properly recorded at December 31, 2005.


                                       39



We expect the tax rate to continue to be slightly less than the federal
statutory rate of 35% in 2006.


FISCAL 2004 COMPARED WITH FISCAL 2003

Sales

IMC. 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. The decrease in volume of
batteries and capacitors was partially offset by increased volume of other IMC
products, primarily coated components.

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

Cost of Sales

The impact on cost of sales as a percentage of sales for 2004 was primarily due
to the following factors:

                                                                     Year ended

a.   Selected contracts negotiated with IMC customers resulted in reduced
     selling prices in 2004. A portion of the 2004 price reductions were based
     on customer volume commitments.
b.   Increased period costs resulting from excess capacity at our wet tantalum
     capacitor manufacturing plant.
c.   Savings related to cost savings initiatives instituted in 2004, primarily
     scrap reductions.
d.   Primarily due to the acquisition of NanoGram in 2004.

SG&A expenses

The increase in SG&A expenses for 2004 is primarily due to the following factors
(in millions):

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


The main causes of the increase in gross costs in 2004 include additional costs
related to the Chief Technology Officer position ($.9 million) and additional
development project expenses ($1.3 million). The balance was primarily due to
the acquisition of NanoGram in March 2004, which was primarily engaged in
research activities. These costs were offset by an increase in development
efforts for projects where the company is reimbursed for achieving certain
development milestones.

Other operating expense

Other operating expense for 2004 and 2003 comprised the following costs (in
millions):

b.   Severance cost from a 7% mid-year reduction in workforce.
c.   Costs associated with the start-up of Tijuana facility.
d.   Costs primarily related to various asset disposals in both periods
     presented.

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 $3.1
million.

Our effective tax rate is above the United States statutory rate primarily as a
result of the recording of the increased valuation allowance.


Liquidity and Capital Resources

The following liquidity and capital resources discussion has been updated for
the effects of the restatement discussed in Note 2 to the condensed consolidated
financial statements.

a.   Short-term investments consist of investments acquired with maturities that
     exceed three months and are less than one year at the time of acquisition,
     equity securities classified as available-for-sale, and auction rate
     securities. The Working capital increased during 2005 primarily due to cash
     flow generated from operations net of capital expenditures reflected in the
     $19.9 million increase in cash and cash equivalents and short-term
     investments.

Revolving Line of Credit

On May 31, 2005, we amended our Senior Secured Credit Facility, which included
changes to the underlying covenants. The amended facility replaced the old $20.0
million revolving credit facility with a new three-year $50.0 million Revolving
Credit Facility ("new revolver"), which contains a $10.0 million sub-limit for
the issuance of commercial or standby letters of credit. The new revolver is
secured by our non-realty assets including cash, accounts and notes


                                       42



receivable, and inventories. The new revolver requires us to comply with two
quarterly financial covenants. The first relates to the ratio of consolidated
net earnings or loss before interest, taxes, depreciation, and amortization
("EBITDA") to Fixed Charges. The second is a Leverage ratio, which is calculated
based on the ratio of Consolidated Funded Debt less Cash, Cash Equivalent
Investments and Short-Term Investments to Consolidated EBITDA, as defined in the
Senior Secured Credit Facility agreement. Interest rates under the new revolver
vary with our leverage. We are required to pay a commitment fee of between .125%
and .250% per annum on the unused portion of the new revolver based on our
leverage. As of December 31, 2005, we had no balance outstanding on the new
revolver.

Our principal sources of liquidity are our operating cash flow combined with our
working capital of $152.0 million at December 31, 2005 and availability under
the new revolver. Historically we have generated cash from operations sufficient
to meet our capital expenditure and debt service needs, other than for
acquisitions. At December 31, 2005, our current ratio was 4.5:1.

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

Operating activities

In total, net cash flows provided by operating activities for the year ended
December 31, 2005 decreased by a nominal amount from 2004. Net income decreased
by $4.1 million, the adjustments to reconcile net cash provided by operating
activities increased by $1.7 million and the changes in other operating assets
and liabilities increased by $2.3 million. Depreciation and amortization
increased primarily due to placing in service the facilities and equipment
related to the Alden and Tijuana facilities and a full year of depreciation on
the ERP system. The 2004 deferred tax benefit was higher than 2005 by $7.9
million, which includes the impact of the valuation allowance increase.
Increased inventories in 2005, primarily due to the start-up of Tijuana facility
operations, were offset by increased accrued liabilities related primarily to
increased incentive compensation.

Investing activities

The majority of the current year increase in acquisition of property, plant and
equipment ("PP&E") was for the following:

     a.   New medical power manufacturing plant in Alden, NY - $9.6 million; and
     b.   New assembly plant in Tijuana, Mexico - $10.4 million.

The increase in PP&E was offset by proceeds of $5.2 million related to the sale
of the Amherst, NY and Carson City, NV real estate in 2005.

In March 2004, we purchased NanoGram for approximately $45.7 million
(subsequently renamed as Greatbatch Technologies Advanced Research Laboratories,
Inc. "ARL"). The most significant elements of the purchase price allocation were
to patented and unpatented technology and goodwill. The costs allocated to
patented and unpatented technology are being amortized over the remaining
estimated useful life of 11.5 years. The residual amount of the allocation of
$35.1 million went to goodwill, which is not amortized but rather subject to
periodic testing as part of the total IMC reporting unit goodwill impairment
testing. The research, development and


                                       43



engineering (RD&E) functions at ARL are being relocated to the Technology Center
in Clarence, New York.

Net short-term investments increased by approximately $8.3 million from 2004 to
2005, which resulted in a decrease in our cash and cash equivalents balance. We
intend to be able to use the majority of our short-term investments for
short-term cash needs as their current maturities are primarily less than three
months.

Financing activities

Payments on capital lease obligations and cash from non-qualified stock option
exercises are the primary financing activities for 2005 and 2004.

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, 2005, our capital structure consisted primarily of $170.0
million of convertible subordinated notes and our 21.7 million shares of common
stock outstanding. We have in excess of $112.1 million in cash, cash equivalents
and short-term investments and are in a position to facilitate future
acquisitions if necessary. We are also authorized to issue 100 million shares of
common stock and 100 million shares of preferred stock. The market value of our
outstanding common stock since our IPO has exceeded our book value; accordingly,
we believe that if needed we can access public markets to sell additional common
or preferred stock assuming conditions are appropriate.

Our capital structure allows us to support our internal growth and provides
liquidity for corporate development initiatives. The current expectation for
2006 is that capital spending is expected to be in the range of $22.0 million to
$27.0 million, of which $5.0 to $7.0 million is attributable to the Tijuana
Facility build-out. The remainder will be used for manufacturing improvements
and normal maintenance capital.

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.

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

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 which is paid semi-annually. See Note
     10 - 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 at December 31, 2005 for continuing construction of
     these facilities are $3.4 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.


                                       45



Impact of Recently Issued Accounting Standards

In June 2005 the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards ("SFAS") No. 154, Accounting Changes and Error
Corrections, ("SFAS 154") a replacement of APB Opinion No. 20, Accounting
Changes, and Statement No. 3, Reporting Accounting Changes in Interim Financial
Statements. SFAS 154 changes the requirements for the accounting for and the
reporting of a change in accounting principle. Previously, most voluntary
changes in accounting principles required recognition by recording a cumulative
effect adjustment within net income in the period of change. SFAS 154 requires
retrospective application to prior periods' financial statements, unless it is
impracticable to determine either the specific period effects or the cumulative
effect of the change. SFAS 154 is effective for accounting changes made in
fiscal years beginning after December 15, 2005. We do not expect that adoption
of SFAS No. 154 will have a material effect on our consolidated financial
position, consolidated results of operations, or liquidity.

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

In December 2004, the FASB issued SFAS No. 123(R) (revised 2004), Share-Based
Payment ("SFAS No. 123(R)"). This statement is a revision of SFAS No. 123,
Accounting for Stock-Based Compensation, and supersedes APB Opinion No. 25,
Accounting for Stock Issued to Employees. This standard requires the Company to
measure the cost of employee services received in exchange for equity awards
based on the grant date fair value of the awards. The cost will be recognized as
compensation expense over the vesting period of the awards. We anticipate
adopting the provisions of SFAS No. 123(R) on January 1, 2006 using the modified
prospective method. Accordingly, compensation expense will be recognized for all
newly granted awards and awards modified, repurchased, or cancelled after
January 1, 2006. Compensation cost for the unvested portion of awards that are
outstanding as of January 1, 2006 will be recognized ratably over the remaining
vesting period. The compensation cost for the unvested portion of awards will be
based on the fair value at date of grant as calculated for our pro forma
disclosure under SFAS 123. We estimate that the effect on net income and
earnings per share in the periods following adoption of SFAS 123(R) will be
consistent with our pro forma disclosure under SFAS No. 123 included in the
notes to our consolidated financial statements, except that estimated
forfeitures will be considered in the calculation of compensation expense under
SFAS 123(R) and will reduce the expense accordingly. Additionally, the actual
effect on net income and earnings per share will vary depending upon the number
of options granted in subsequent periods compared to prior years. We currently
estimate that the compensation expense related to the adoption of SFAS 123(R)
will be between $5.0 million and $6.0 million based on options expected to be
vested and granted in 2006 as well as the vesting of outstanding options at
December 31, 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


                                       46



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 the adoption of SFAS No. 151 will have a material effect on our
consolidated financial position, consolidated results of operations, or
liquidity.


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, 2005, we did not have any borrowings outstanding
under our line of credit and thus no interest rate sensitive financial
instruments other than short-term investments. We do not believe that the impact
of fluctuations in interest rates on short-term investments will have a material
effect on our consolidated financial statements.

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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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

We have audited the accompanying consolidated balance sheets of Greatbatch, Inc.
and subsidiaries (the "Company") as of December 30, 2005 and December 31, 2004,
and the related consolidated statements of operations and comprehensive income,
stockholders' equity, and cash flows for each of the three years in the period
ended December 30, 2005. Our audits also included the consolidated financial
statement schedule at Item 15(a) (2). These consolidated financial statements
and consolidated financial statement schedule are the responsibility of the
Company's management. Our responsibility is to express an opinion on the
consolidated financial statements and consolidated financial statement schedule
based on our audits.

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

In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of the Company as of December 30, 2005
and December 31, 2004, and the results of its operations and its cash flows for
each of the three years in the period ended December 30, 2005, in conformity
with accounting principles generally accepted in the United States of America.
Also, in our opinion, such consolidated financial statement schedule, when
considered in relation to the basic consolidated financial statements taken as a
whole, presents fairly, in all material respects, the information set forth
therein.

We have also audited, in accordance with the standards of the Public Company
Accounting Oversight Board (United States), the effectiveness of the Company's
internal control over financial reporting as of December 30, 2005, 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 14, 2006 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.

As discussed in Note 2, the accompanying consolidated financial statements as of
and for the period ended December 31, 2004 have been restated.

                                   statements


                                       53



                                GREATBATCH, INC.
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (as restated)
- --------------------------------------------------------------------------------



1.   DESCRIPTION OF BUSINESS

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

     The Company has revised its Consolidated Statement of Operations and
     Comprehensive Income to eliminate presentation of gross profit effective
     December 31, 2005. At the same time, the Company has associated the
     amortization expense of intangible assets with cost of sales.

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

     Financial Statement Year End - The Company utilizes a fifty-two,
     fifty-three week fiscal year ending on the Friday nearest December 31st.
     Fiscal 2005, 2004, and 2003 ended on December 30, 2005, December 31, 2004,
     and January 2, 2004, respectively. For clarity of presentation, the Company
     describes all fiscal years as if the year-end is December 31st.


2.   RESTATEMENTS

     Subsequent to the original filing and Amendment No. 1 of the Company's 2004
     Form 10-K, the Company concluded that its consolidated financial statements
     should be restated. During the completion of its 2005 year-end control
     procedures over the accounting for income taxes, management discovered an
     error related to the 2004 provision for income taxes. The correction of the
     error represents an increase in the 2004 provision for income taxes with a
     corresponding decrease in refundable income taxes and an adjustment to the
     diluted weighted average shares outstanding due to the antidilutive effect
     of the error. The consolidated balance sheet as of December 31, 2004,
     consolidated statements of operations and comprehensive income, cash flows,
     and stockholders' equity for the year ended December 31, 2004 have been
     restated in order to reflect this correction.

     The restatement has been made to the Consolidated Balance Sheet,
     Consolidated Statement of Operations and Comprehensive Income, Consolidated
     Statement of Cash Flows and Consolidated Statement of Stockholders' Equity
     as follows (in thousands except per share amounts):

3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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

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

     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, 2005 and
     2004 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 by utilizing prevailing market
     conditions or appraisals as needed. At December 31, 2003, the Company
     classified its Amherst, NY facility as held for sale. The facility was sold
     in 2005.

     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.


                                       56



     Impairment of Long-lived Assets - The Company assesses the impairment of
     definite lived 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 group to the related total future undiscounted cash
     flows. If an asset group's carrying value is not recoverable through
     related cash flows, the asset group is considered to be impaired.
     Impairment is measured by comparing the asset group'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 definite lived
     assets in 2005, 2004 or 2003.

     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.
     Indefinite lived intangible assets such as trademark and names are assessed
     for impairment on an annual basis, or more frequently if certain events
     occur or circumstances change, by comparing the fair value of the asset to
     their carrying value. The fair value is determined by using a "relief for
     royalty" approach. Fair values for reporting units are determined based on
     discounted cash flows, market multiples or appraised values as appropriate.
     The Company has determined that, based on the impairment tests performed,
     no impairment of goodwill or trademark and names has occurred. Note 17 -
     Business Segment information contains an analysis of goodwill by segment.

     Other Assets - Other assets include long-term investments in securities,
     which comprise marketable equity securities and other securities and
     investments for which market values are not readily available. Marketable
     equity securities are classified as available-for-sale and reported at fair
     value. Fair value is based on quoted market prices as of the end of the
     reporting period. Unrealized gains and losses are reported, net of their
     related tax effects, as accumulated other comprehensive loss, a component
     of stockholders' equity.

     Investments in equity securities that do not have readily determinable fair
     values are accounted for using the cost method. The Company assesses
     impairment of these securities at the end of the reporting period. If an
     impairment is considered other than temporary, an impairment loss is
     recognized and the fair value of the investment becomes its new cost basis.
     The aggregate recorded amount of cost method investments at December 31,
     2005 and 2004 were $1.1 million and $1.0 million, respectively. Some of
     these investments are in research and development companies where the fair
     value may be subject to future fluctuations, which could be significant.


                                       57



     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 expense (benefit) is 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 Sales. In certain instances the
     Company obtains component parts for sub-assemblies from its customers. The
     cost of these customer supplied component parts amounted to $7.8 million in
     2005 and was excluded from the sales and cost of goods sold amounts
     recognized by the Company.

     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. The primary costs are salary and benefits for personnel.

     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.

     Net earnings per diluted share for 2005 and 2004 exclude the effect of
     4,219 shares related to the contingent convertible notes, as the effect is
     anti-dilutive. Included in stock-based compensation cost is company stock
     contributed to the 401(k) plan.

     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 are calculated by adjusting for
     potential common shares, which consist of stock options, unvested
     restricted stock and contingently convertible instruments. Holders of our
     convertible notes may convert them into shares of the Company's common
     stock under certain circumstances (see Note 10 - Debt for a description of
     our convertible subordinated notes).

     The Company adopted Emerging Issues Task Force ("EITF") Issue 04-08, The
     Effect of Contingently Convertible Instruments on Diluted Earnings Per
     Share, in the fourth quarter of 2004. Under EITF 04-08, the Company must
     include the effect of the conversion of its 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.

     Net earnings per diluted share for 2005 and 2004 exclude the effect of
     4,219,000 shares related to the contingent convertible notes, as the effect
     is anti-dilutive. The options for which the exercise price was less than
     the average market price for the Company's stock for 2005, 2004 and 2003
     were 908,000, 843,000, and 258,000, respectively.

     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, the Company's
     only component of comprehensive income is its net income. For 2005 and
     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.

     Reclassifications - Certain reclassifications were made to the prior years'
     financial statements to conform to the current year presentation. None of
     the reclassifications affected net income or stockholders' equity.

     Recent Accounting Pronouncements -- In June 2005 the Financial Accounting
     Standards Board ("FASB") issued Statement of Financial Accounting Standards
     ("SFAS") No. 154, Accounting Changes and Error Corrections, ("SFAS 154") a
     replacement of APB Opinion No. 20, Accounting Changes, and Statement No. 3,
     Reporting Accounting Changes in Interim Financial Statements. SFAS 154
     changes the requirements for the accounting for and the reporting of a
     change in accounting principle. Previously, most voluntary changes in
     accounting principles required recognition by recording a cumulative effect
     adjustment within net income in the period of change. SFAS 154 requires
     retrospective application to prior periods' financial statements, unless it
     is impracticable to determine either the specific period effects or the
     cumulative effect of the change. SFAS 154 is effective for accounting
     changes made in fiscal years beginning after December 15, 2005. The Company
     does not expect that adoption of SFAS No. 154 will have a material effect
     on its consolidated financial position, consolidated results of operations,
     or liquidity.

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

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


                                       62



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

     The Company estimates that the effect on net income and earnings per share
     in the periods following adoption of SFAS 123(R) will be consistent with
     the Company's pro forma disclosure under SFAS No. 123, except that
     estimated forfeitures will be considered in the calculation of compensation
     expense under SFAS 123(R). Additionally, the actual effect on net income
     and earnings per share will vary depending upon the number of options
     granted in subsequent periods compared to prior years. However, the
     estimate for the additional compensation expense for 2006 under SFAS 123(R)
     is between $5.0 and $6.0 million on a pre-tax basis based on options
     expected to be vested and granted in 2006 as well as the vesting of
     outstanding options at December 31, 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 the adoption of SFAS No. 151
     will have a material effect on its consolidated financial position,
     consolidated results of operations, or liquidity.


4.   ACQUISITIONS

     During 2004, the Company completed the acquisition of 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.

     The acquisition was accounted for using the purchase method of accounting
     and accordingly, the results of the operations of the acquisition 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 ("CSN") 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


                                       67



     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 the Company's subsidiaries.

     Concurrent with the issuance of the notes, the Company used approximately
     $72.5 million of the proceeds from this private placement to pay off a
     previously existing bank 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,
     2005 and 2004 based on quoted market prices was $149.0 million and $154.7
     million, respectively.

      Capital Lease Obligations

     The fair-value of the capital leases as of December 31, 2005 was $0.5
     million based on interest rates in effect at year-end.

     Revolving Line of Credit

     On May 31, 2005, the Company amended its Senior Secured Credit Facility,
     which included changes to the underlying covenants. The amended facility
     replaced the old $20.0 million revolving credit facility with a new
     three-year $50.0 million Revolving Credit Facility ("new revolver"), which
     contains a $10.0 million sub-limit for the issuance of commercial or
     standby letters of credit. The new revolver is secured by the Company's
     non-realty assets


                                       68



     including cash, accounts and notes receivable, and inventories. The new
     revolver requires the Company to comply with two quarterly financial
     covenants, as defined. The first relates to the ratio of consolidated net
     earnings or loss before interest, taxes, depreciation, and amortization
     ("EBITDA") to Fixed Charges. The second is a Leverage ratio, which is
     calculated based on the ratio of Consolidated Funded Debt less Cash, Cash
     Equivalent Investments and Short-Term Investments to Consolidated EBITDA,
     as defined in the Senior Secured Credit Facility agreement. Interest rates
     under the new revolver vary with the Company's leverage. The Company is
     required to pay a commitment fee of between .125% and .250% per annum on
     the unused portion of the new revolver based on the Company's leverage. As
     of December 31, 2005, the Company had no balance outstanding on the new
     revolver.

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


11.  EMPLOYEE BENEFIT PLANS

     Savings Plan - The Company sponsors a defined contribution 401(k) plan,
     which covers substantially all of its employees. The plan provides for the
     deferral of employee compensation under Section 401(k) and a discretionary
     Company match. In 2005, 2004, and 2003, this match was $0.35 per dollar of
     participant deferral, up to 6% of the total compensation for each
     participant. Net costs related to this defined contribution plan were
     approximately $0.9 million in 2005 and 2004, and $0.8 million in 2003.

     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 amount is contributed to the 401(k) plan in the
     form of Company stock. Compensation cost recognized related to the defined
     contribution was approximately $2.8 million in 2005 and $2.7 million in
     2004 and 2003, respectively.

     As of December 31, 2005, the 401(k) Plan held 514,907 shares of GB stock
     and there were 106,897 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 30, 2005. The final number
     of shares contributed to the plan was 110,246, computed based on the
     closing market price of the shares on the actual contribution date of
     February 13, 2006, 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.

13.  RESTRICTED STOCK PLANS

     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.

     The Company's 2005 Stock Incentive Plan ("2005 Plan") authorizes the
     issuance of restricted stock of up to 500,000 shares, subject to the terms
     of the plan. The restricted stock generally vests 50% on the second
     anniversary of the date of the award and 25% on the third and fourth
     anniversaries of the date of the award and vary depending upon the
     achievement of earnings targets and also upon the terms of each specific

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

     (e) Costs to exit development agreement. There was a $1.15 million charge
     recorded in other operating expenses for the IMC segment during the second
     quarter of 2005 for charges associated with the discontinuation of a drug
     pump development agreement.

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

     The total estimated cost for this facility consolidation plan is
     anticipated to be between $7.9 million and $8.3 million. The Company
     expects to incur and pay the remaining cost over the next six fiscal
     quarters, through June 2007. The major categories of costs include the
     following:

     o    Costs related to the shutdown of the Columbia Facility and ARL and the
          move and consolidation of the RD&E functions to Clarence, NY:
          a.   Severance and retention - $2.7 to $2.8 million;
          b.   Personnel (including travel, training and duplicate wages) - $1.5
               million
          c.   Accelerated depreciation/asset write-offs - $0.7 million; and
          d.   Other - $0.3 to $0.4 million.

     o    Costs related to Tijuana Facility consolidation No. 2:


                                       75



          a.   Production inefficiencies and revalidation - $0.4 to $0.5
               million;
          b.   Relocation and moving - $0.2 million;
          c.   Personnel (including travel, training and duplicate wages) - $2.0
               to $2.1 million; and
          d.   Other (including asset write-offs) - $0.1 million.

     All categories of costs are considered to be cash expenditures, except for
     accelerated depreciation and asset write-offs. Once the moves are
     completed, the Company anticipates annual cost savings in the range of $5.0
     to $6.0 million. The expenses for the Columbia Facility and ARL shutdowns,
     the Tijuana Facility consolidation No. 2 and the RD&E consolidation are
     included in the IMC business segment.

     Accrued liabilities at December 31, 2005 related to the Columbia Facility
     and ARL shutdowns and the RD&E consolidation comprised the following (in

     Other Tijuana start-up expenses (not associated with the Carson City
     Facility or Columbia Facility consolidation) amount to $1.3 million. These
     expenses are primarily related to the initial start-up of the value added
     assembly business.

     (g) Asset dispositions. There was a $2.8 million write-down of automated
     cathode assembly equipment for the IMC segment during the third quarter of
     2005. This charge was primarily related to a decision not to continue to
     use some battery production equipment. The manufacturing process related to
     this equipment did not match the Company's overall manufacturing strategy.
     The remainder of the expense is for other property, plant, and equipment
     dispositions. Asset dispositions in 2004 amounted to $0.9 million. Other
     operating expenses in 2003 were primarily asset disposition charges.

     For the year ended December 31, 2004, there were two charges included in
     other operating expense in the Company's Consolidated Statement of
     Operations as follows:


                                       76



     Patent acquisition. The Company recorded a $2.0 million pre-tax charge
     associated with the acquisition of certain patents during the second
     quarter of 2004. The acquired patents cover how wet tantalum capacitors are
     used in an Impantable Cardioverter Defibrillator ("ICD"). 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 believed it was appropriate to record the $2.0
     million acquisition cost in accordance with its economic substance as a
     period expense. This expense is related to the IMC business segment.

     Severance charges. In response to a reduction in sales for the 2004 year,
     the Company implemented a 7% workforce reduction during June 2004, 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 ECP, respectively. The remaining $0.1 million
     related to corporate employees and is included in unallocated operating
     expenses. There was no remaining accrued severance as of December 31, 2004
     related to this event as all amounts were paid.

     As of December 31, 2005, the Company has available $2.8 million of federal
     net operating loss carryforwards that begin expiring in 2022, $0.2 million
     of state net operating loss carryforwards that begin to expire in 2018 and
     $4.7 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, 2005 related to the valuation of an investment and certain
     state investment tax credits and NOLs will not be realized. The valuation
     allowance increase in 2005 was primarily related to the allowance for the
     state investment tax credits and NOLs

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

     In 2005, 2004, and 2003, 75,887, 43,911, and 39,090 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 $0.3 million, $0.1 million, and $0.3
     million in 2005, 2004, and 2003, respectively. These tax benefits have also
     been recognized in the consolidated balance sheet as a reduction of current
     income taxes payable.

     In accordance with Financial Accounting Standards No. 5, Accounting for
     Contingencies, the Company records tax contingencies when the exposure item
     becomes probable and reasonably estimable. In an audit during 2005, the
     Internal Revenue Service ("IRS") has questioned the amount of the deduction
     relative to the interest expense associated with the CSN. A deferred tax
     liability has been established for the difference between the amount of
     interest expense deducted for income taxes and the amount recorded as
     expense for book purposes. The amount of the recorded deferred income tax
     liability as of December 31, 2005 is approximately $11,428. If the entire
     interest expense deduction is disallowed by the IRS, an additional $3.5
     million would be payable, and recorded as an expense. The Company maintains
     that the risk of the entire interest expense deduction being disallowed is
     minimal. If the amount of interest expense deduction up to the difference
     between the amount recorded for books and tax is disallowed, a portion of
     the deferred income tax liability would become currently payable. The
     Company believes that it has appropriate support for its income tax
     provision and that the income tax balances have been properly recorded at
     December 31, 2005.

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.

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

     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 in the IMC segment. 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 $1.6 million, $1.3 million, and
     $1.5 million, for 2005, 2004, and 2003, respectively.

     Product Warranties - The change in the aggregate product warranty liability
     for the years ended December 31, 2005 and 2004 is as follows (in
     thousands):

     Operating Leases - The Company is a party to various operating lease
     agreements for buildings, equipment and software. The Company incurred
     operating lease expense of $2.7 million, $2.2 million, and $1.7 million, in
     2005, 2004 and 2003, respectively.

     Minimum future annual operating lease payments are $2.1 million in 2006;
     $1.4 million in 2007; $0.9 million in 2008; $0.8 million in 2009; $0.8
     million in 2010 and $3.2 million thereafter.

     The Company primarily leases buildings which account for the majority of
     the future lease payments. Lease expense includes the effect of escalation
     clauses and leasehold improvement incentives which are accounted for
     ratably over the lease term.

     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


                                       80



     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.

     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 at December 31, 2005 for continuing construction of
     these facilities are $3.4 million and will be financed by cash, cash
     equivalents, and short-term investments on hand, or from cash flows from
     operations.


17.  BUSINESS SEGMENT INFORMATION

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

     The Company defines segment income from operations as sales less cost of
     sales including amortization and expenses attributable to segment-specific
     selling, general and administrative, research, development and engineering
     expenses and other operating expenses. Segment income also includes a
     portion of non-segment specific selling, general and administrative, and
     research, development and engineering expenses based on allocations
     appropriate to the expense categories. The remaining unallocated operating
     expenses are primarily corporate headquarters and administrative function
     expenses. The unallocated operating expenses along with other income and
     expense are not allocated to reportable segments. Transactions between the
     two segments are not significant. Segment assets are intended to correlate
     with invested capital. The amounts include accounts receivable,
     inventories, net property, plant and equipment, intangible assets,
     trademark and names, and


                                       81



     goodwill. Corporate assets consist primarily of cash, short-term
     investments, deferred taxes and net property, plant and equipment for
     corporate headquarters. The accounting policies of the segments are the
     same as those described and referenced in Note 3.


                                       82

ITEM 9A.  CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

The management of Greatbatch, Inc. ("the Company"), under the supervision and
with the participation of the Company's Chief Executive Officer and Chief
Financial Officer, carried out an evaluation of the effectiveness of the design
and operation of the Company's disclosure controls and procedures as of December
31, 2005 (the "Evaluation"). Based upon the Evaluation, the Company's Chief
Executive Officer and Chief Financial Officer concluded that the Company's
disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e))
are effective in ensuring that material information relating to the Company,
including its consolidated subsidiaries, is made known to them by others within
those entities as appropriate to allow timely decisions regarding required
disclosure, particularly during the period in which this annual report was being
prepared.

Changes in Internal Control Over Financial Reporting

During the fourth quarter 2005, we had taken remedial action to eliminate the
material weaknesses in our system of internal controls over financial reporting
that existed as of December 31, 2004.

The remedial actions included:

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

     o  Establishment of formal quarterly disclosure meetings which include
          our third party tax advisors to review significant transactions during
          the period as well as to review and discuss new accounting
          presentation and disclosure guidelines. Our independent registered
          public accounting firm, although not part of our control structure,
          participates in these meetings.
     o  Enhanced our financial reporting practices to include the use of
          multiple third-party financial reporting technical alerts that we
          utilize to evaluate our accounting policies and financial statement
          disclosures.
     o  Engaged a third-party professional advisor to assist in the internal
          control procedures over the tax area.
     o  Performed additional control procedures related to "critical
          spreadsheets" associated with the tax area including recalculation of
          formulas.

These additional control procedures have appropriately remediated the material
weaknesses that resulted in the restatements of the 2004 financial statements.

Management's Report on Internal Control Over Financial Reporting

The Company's certifying officers are responsible for establishing and
maintaining adequate internal control over financial reporting. The Company's
internal control over financial reporting is designed and maintained under the
supervision of its certifying officers to provide reasonable assurance regarding
the reliability of financial reporting and the preparation of the Company's
financial statements for external reporting purposes in accordance with
accounting principles generally accepted in the United States of America.

As of December 31, 2005, management conducted an assessment of the effectiveness
of the Company's internal control over financial reporting based on the
framework established in Internal Control - Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission. Based on this
assessment, management has determined that the Company's internal control over
financial reporting as of December 31, 2005 is effective.

Management's assessment of the effectiveness of internal control over financial
reporting as of December 31, 2005 has been audited by Deloitte & Touche LLP, the
Company's independent registered public accounting firm, whose unqualified
opinion on management's assessment of the effectiveness of internal control over
financial reporting as of December 31, 2005 is expressed in their report
included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


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

We have audited management's assessment, included in the accompanying
Management's Report on Internal Control Over Financial Reporting, that
Greatbatch, Inc. and subsidiaries (the "Company") maintained effective internal
control over financial reporting as of December 30, 2005, 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.


                                       89



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

In our opinion, management's assessment that the Company maintained effective
internal control over financial reporting as of December 30, 2005, 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 30, 2005, 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 consolidated financial statement schedule as of and for the year
ended December 30, 2005 and our report dated March 14, 2006 expressed an
unqualified opinion on those consolidated financial statements and consolidated
financial statement schedule and included an explanatory paragraph regarding the
restatement discussed in Note 2.
