                             SUBSCRIPTION AGREEMENT

        This Subscription Agreement (this "Agreement"), dated as of
July 31, 2000, is made by Hitachi Maxell, Ltd., a Japanese corporation
(the "Investor"), and Wilson Greatbatch Technologies, Inc., a Delaware
corporation (the "Corporation").

                                 R E C I T A L S

        A. The Investor desires to subscribe for shares of common stock of the
Corporation. The subscription by the Investor provided for herein is being made
in connection with, and subject to the consummation of the transactions provided
for in, a certain Stock Purchase Agreement among Investor, the Corporation, and
Battery Engineering, Inc., a Massachusetts corporation, dated the same date as
of this Agreement (the "Purchase Agreement").

        B. The Corporation is willing to sell, on the terms and subject to the
conditions herein set forth, the Shares (as hereinafter defined) to the
Investor.

        NOW, THEREFORE, in consideration of the premises, the mutual covenants
and agreements contained herein and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the Investor and
the Corporation agree as follows:

        1. ISSUANCE AND SALE OF STOCK. Subject to the terms and conditions of
this Agreement and on the basis of the representations and warranties set forth
herein, the Corporation agrees to issue and sell to the Investor, and the
Investor agrees to purchase from the Corporation, Three Hundred Thirty Three
Thousand Three Hundred and Thirty Four (333,334) shares (the "Shares") of the
common stock, par value $.001 per share ("Common Stock"), of the Corporation at
the price of Nine Dollars ($9.00) per share, for an aggregate purchase price of
$3,000,006 (the "Purchase Price"); provided, however, that if there occurs,
prior to Closing: (i) any dividend or other distribution of Common Stock to the
present holders of Common Stock, or (ii) any stock split, reverse stock split,
repurchase, combination, share exchange or other transaction affecting the
Common Stock of the Corporation (collectively, "Stock Adjustment Event"), the
aggregate Purchase Price shall remain the same but the number of Shares shall be
appropriately adjusted to reflect any such Stock Adjustment Event. For example,
if there occurs a one (1) for two (2) reverse stock split of Common Stock, the
number of Shares would be reduced from 333,334 to 166,666; if there occurs a two
(2) for one (1) stock split of Common Stock, the number of Shares would be
increased from 333,334 to 666,666. The purchase price shall be paid to the
Corporation by wire transfer delivered by the Investor to the Corporation at the
Closing (as hereinafter defined).

        2. THE CLOSING. The consummation of the purchase of the Shares (the
"Closing") shall take place at the offices of Hodgson, Russ, Andrews, Woods &
Goodyear, LLP, 65 East 55th Street, New York, New York 10022 (or at such other
location as may be agreed to

<PAGE>

by the parties) on the same day as the transactions provided for in the Purchase
Agreement. At the Closing:

        2.1 The Corporation shall issue and deliver a stock certificate
representing the Shares to the Investor;

        2.2 The Investor shall deliver the Purchase Price to the Corporation by
wire transfer of immediately available funds;

        2.3 The Corporation and the Investor shall execute the Stockholders

in substantially the form attached as EXHIBIT C to the Purchase Agreement;

        2.5 The Corporation shall deliver an Officer's Certificate certifying
that the representations and warranties of the Corporation set forth in Article
4 are true and correct as of the date of Closing; and

        2.6 The Investor shall deliver an Officer's Certificate certifying that

        3.4 INVESTMENT FOR OWN ACCOUNT. The Investor is acquiring the Shares for

                              NON-COMPETE AGREEMENT

      THIS AGREEMENT (this "Agreement"), dated as of the 7th day of August,
2000, is between HITACHI MAXELL, LTD., a Japanese corporation with its principal

("Seller"), and WILSON GREATBATCH TECHNOLOGIES, INC., a Delaware corporation
having its principal place of business at 10,000 Wehrle Drive, Clarence, New
York 14031 ("WGL").

                                    RECITALS:

      WHEREAS, Seller is the sole shareholder of Battery Engineering, Inc., a
Massachusetts corporation ("BEI"); and

      WHEREAS, Seller, WGL and BEI are parties to a certain Stock Purchase
Agreement, dated as of July 31, 2000 (the "Purchase Agreement"), pursuant to
which WGL is purchasing all of the issued and outstanding shares of stock of BEI
from Seller; and

      WHEREAS, BEI is engaged in the business of the design, manufacture and
sale of batteries for certain commercial applications (the "Business") and WGL
intends to operate the Business of BEI on and after the closing of the
transactions contemplated by the Purchase Agreement; and

      WHEREAS, during the course of many years, Seller has had access to, and
has gained knowledge with respect to, the Business of BEI; and

      WHEREAS, as a condition to closing the Purchase Agreement, WGL has
required Seller to agree not to compete with WGL or BEI.

      NOW, THEREFORE, Seller and WGL agree as follows:

      1.    NON-COMPETITION.

            1.1 For the period beginning on the date of this Agreement and
ending two (2) years thereafter (the "Covenant Period"), Seller agrees that it
will not:

                (a) directly or indirectly, for its own account or as an agent,
employee, officer, director, trustee, consultant or member, partner, shareholder
or other equity holder of any person or entity (other than as an owner of 1% or
less of any class of publicly traded securities) or member of any firm or
otherwise, anywhere in the United States, (A) sell or distribute or attempt to
sell, distribute or market any product that uses oxyhalide technology, carbon

services from BEI within six (6) months prior to the date of this Agreement; or

                (b) employ or solicit the employment of (x) any person who was
employed by WGL on the date of this Agreement or within six (6) months prior to

            1.2 The restrictions in Section 1.1(a) above shall not apply to: (i)

this Agreement, negotiating a business relationship.

            1.3 Seller acknowledges and agrees that the restrictions in this
Section 1 are reasonable, legitimate and fair to Seller in light of the WGL's
purchase of the shares of BEI from Seller pursuant to the Purchase Agreement.

            1.4 The Seller agrees that the consideration it has received
pursuant to the Purchase Agreement is full and adequate compensation for its
covenant in this Section 1.

      2.    CONFIDENTIAL INFORMATION.

                (a) Seller has had access to, and has gained knowledge with
respect to, all aspects of the Business, and BEI's trade secrets, financial
results and information, processes and techniques, methods of doing businesses
and information concerning customers and suppliers, and other valuable and
confidential information, which is not generally known to the public (the
"Confidential Information"). The parties acknowledge that unauthorized
disclosure or misuse of the Confidential Information may cause irreparable
damage to BEI and the Business subsequent to the closing of the transactions
contemplated by the Purchase Agreement. The parties also agree that covenants by
Seller not to make unauthorized disclosures of the Confidential Information are
essential to the growth and stability of the Business. Accordingly, Seller
agrees that it shall not use or disclose any Confidential Information obtained
by it in the course of its past connection with the Business, and Seller further
agrees that it shall not use or disclose any Confidential Information obtained
by it in the course of any future connection it has with BEI or the Business.

      3. EQUITABLE REMEDIES. Seller (a) acknowledges that the failure of Seller
to comply with any provision of Section 1 or 2 of this Agreement will cause WGL
irrevocable harm and that a remedy at law for such failure would be an
inadequate

<PAGE>

remedy for WGL and (b) consents to WGL's obtaining from a court having
jurisdiction specific performance, an injunction, a restraining order or any
other equitable relief in order to enforce such compliance. WGL's right to
obtain such equitable relief shall be in addition to any other remedy to which
WGL is entitled under applicable law (including, but not limited to monetary
damages).

      4. ATTORNEYS' FEES. If any action at law or equity is necessary to enforce
or interpret the terms of this Agreement, the prevailing party shall be entitled
to reasonable attorneys' fees, costs, and necessary disbursements in addition to
any other relief to which he or it may be entitled.

      5. GOVERNING LAW. This Agreement shall be construed under and in
accordance with the laws of the State of New York.

      6. BINDING EFFECT. This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective heirs, executors,
administrators, legal representatives, successors, and assigns where permitted
by this Agreement.

      7. SEVERABILITY. In case any one or more of the provisions contained in
this Agreement shall for any reason be held to be invalid, illegal, or
unenforceable in any respect, such invalidity, illegality, or unenforceability
shall not affect any other provision hereof, and this Agreement shall be
construed as if such invalid, illegal, or unenforceable provision had never been
contained herein.

      8. ENTIRE AGREEMENT. This Agreement constitutes the entire agreement of
the parties hereto with respect to the subject matter of this Agreement, and
supersedes any prior understandings or written or oral agreements between the
