I. CONTRACT PERIOD

      This AGREEMENT shall remain in effect from the effective date (February 1,
      1999) through December 31, 2001. This agreement may be renewed from year
      to year after the initial term with the mutual agreement of both parties.

      For the purpose of calculating annual volumes during year one of this
      AGREEMENT, the period is January 01, 1999 through December 31, 1999.

II. CONTRACT TERMS:

      A.    Guidant/CRM may terminate this agreement at any time with one (1)
            year written notice to WGL. This notice of cancellation, for early
            termination purposes, must occur no later than one (1) year prior to
            originally scheduled expiration of agreement.

      B.    In the event of early termination by Guidant/CRM, WGL will invoice

      D.    This agreement may not be modified, changed or terminated orally. No
            change, modification, addition, or amendment shall be valid unless
            in writing indicating an intent to modify this agreement and signed
            by an authorized officer of each party.

III. CONTINUITY OF SUPPLY:

      A.    In the event WGL experiences a major catastrophe that would prohibit
            the shipment of implantable lithium power sources, WGL will
            immediately notify Guidant/CRM of the nature of the problem and
            begin discussions on the length of time that shipments will be
            delayed. If the delay will impact Guidant/CRM's supply of product to
            the field, Guidant/CRM and WGL will immediately enter into
            negotiations for the following:

            1.    The transfer of tooling used on Guidant/CRM models to another
                  lithium battery manufacturer, and

            2.    If a technology transfer is required, the cost for such a
                  technology transfer will be negotiated at the time of the
                  catastrophe.

      B.    WGL must give Guidant/CRM (2) years prior written notice of any
            intent to discontinue supply of implantable power sources to
            Guidant/CRM, but WGL shall not be bound after Dec. 31, 2001 to the
            pricing set forth in Article IV.

IV. PRICE:

      Prices per model will be as called out on the purchase order based on
      anticipated annual volumes. Prices are in effect for the original contract
      period, February 01, 1999 through December 31, 2001. Where pricing is
      specified in B and C below on an annual forecast volume by Guidant, and
      the minimum volume requirements for that pricing level are not achieved,
      WGL will back-bill Guidant for the difference in price between the volume
      levels. Payment terms are net 30, FOB Clarence, New York.

                       2. POWER SOURCE SUPPLY ARRANGEMENTS

            2.1 Supply of Requirements. The Company hereby agrees to purchase
from WGL, and WGL hereby agrees to sell to the Company, * of the Company's *
requirements for Batteries for use in the Company's implantable medical devices
during the term of this Agreement, upon and subject to the terms and conditions
set forth in this Agreement. This Agreement shall apply to all of the facilities
of the Company and of its Affiliates on a worldwide basis. In addition,
regardless of location, the Company will not replace any existing WGL battery
models with Batteries supplied by others.

            2.2 Price. Pricing for Batteries during the remainder of 1997 shall
be as set forth in the 1995 Purchase Contract. Subject to Section 2.8, the
prices for Batteries to be purchased by the Company commencing as of January 1,
1998 shall be determined as provided for in this Section 2.2, and shall apply
regardless of the location of the Company's facility to which Batteries will be
delivered.

            (a)   The prices for lithium iodine batteries having a thickness of
                  5 mm or greater shall be * per cell, beginning on January 1,
                  1998 through the termination of this Agreement on December 31,
                  2001.

            (b)   The prices for (i) lithium iodine Batteries having a thickness
                  of less than 5 mm and (ii) lithium iodine Battery models the
                  volume of which is less than * cells per Contract Year shall
                  be the price set forth in Section 2.2(a) plus a premium of *.

            (c)   The price for titanium CFx Batteries are * per cell, beginning
                  January 1, 1998 through the termination of this Agreement on
                  December 31, 2001.

            (d)   There shall be an extra charge to the Company for unique pin
                  modifications in the Batteries including, but not limited to,
                  a modification such as the gold plating requirement in
                  Pacesetter Model 9438.

            (e)   If the Company requires power sources which are other than
                  WGL's current standard production cells or which use
                  alternative battery chemistry, the pricing shown on Attachment
                  B will apply.

                                     Page 3
<PAGE>

            (f)   If the Company proceeds with the development of a "hi-value
                  pacemaker," WGL will propose separate pricing and
                  specifications for the Battery and other components for any
                  such new pacemaker product of the Company. In that regard, the
                  Company agrees to involve WGL during the planning and design
                  of such pacemaker in order to ensure that the product will be
                  competitive in cost (including Battery) for the intended
                  market. WGL agrees that if the Company determines that, for
                  competitive reasons, the new product must include a power
                  source that WGL does not then have rights to, WGL will use its
                  reasonable best efforts to obtain a license or other rights to
                  manufacture and sell such Battery. The parties will agree in
                  writing on the pricing and other terms and conditions of sale
                  for WGL's Battery and any other components for any such
                  hi-value pacemaker product.

            2.3 Forecasts. The parties agree as follows:

            (a) The Company will provide WGL with a forecast setting forth three
(3) months firm orders for Batteries and an additional nine (9) months forecast
stating anticipated Battery needs. This forecast will provide WGL with a total
of twelve (12) months projected requirements for planning purposes at all times.
Such forecast, including a new firm order for Batteries, will be provided each
succeeding month.

            (b) WGL shall not be required to manufacture more than * of the
Company's twelve (12) month forecast quantity of Batteries in any one three (3)
month period, except upon not less than a six (6) month prior written notice.
The sole exception to this provision shall be if WGL has fallen behind on past
deliveries due to its own fault, in which case WGL shall be required to
manufacture and deliver each month up to * more than the average monthly
quantities which were scheduled for the preceding three-month period until WGL
is back on schedule with its deliveries.

            2.4 Payment Terms. Payment terms for Batteries are as follows: (a)
for Consignment Batteries purchased by the Company, by the thirtieth (30th) day
after the day on which Consignment Batteries shall have been withdrawn by the
Company or (b) for all other Batteries purchased by the Company, net 30 days
from the date of the invoice, F.O.B. Clarence, NY or point of shipment,
whichever is applicable. Payment terms for tooling and engineering charges are
net 30 days from the date of the invoice. If payments are delinquent, a late
charge fee of * per month will be imposed. The calculation will be based on
thirty (30) day months the percentage will be pro rated based upon the exact
number of days late. Payment terms for these charges will be net 30 days.

                                     Page 4

            2.5 Consignment.

            (a) As promptly after the execution and delivery of this Agreement
as the operations of WGL will permit, but by no means later than January 31,
1998, and the parties shall mutually agree, WGL will consign and ship to itself,
in care of the Company, Consignment Batteries the number of which shall be
approximately equal to * (calculated by dollar cost) of the Batteries purchased
by the Company from WGL in 1997. Thereafter, during the term of this Agreement,
WGL will ship additional quantities of Consignment Batteries to the Company so
that the number of Consignment Batteries at all times shall be approximately
equal to * of the Company's total purchases of Batteries for the preceding
Contract Year (calculated by dollar cost). WGL shall use its reasonable best
efforts to maintain the model mix of Consignment Batteries as close as is
reasonably possible to Company's most recent twelve (12) month forecast of
projected Battery requirements. The Consignment Batteries shall be delivered to
the Company location at which the Company will use the Batteries, based upon
information supplied by the Company to WGL. However, WGL shall have the option
not to make any such shipment unless the Company shall have paid all sums owing
with respect to all previous quantities of Batteries purchased by the Company.

            (b) WGL shall use Federal Express or UPS or other recognized courier
services to ship Consignment Batteries, as directed by the Company, and shall
charge the Company's account with such courier service. Consignment Batteries
shall be received by the Company and stored by the Company as WGL's property.
All charges and expenses for receiving, handling, and storing such material
shall be paid by the Company. The Consignment Batteries in all cases shall be
carefully segregated from other goods either of the same or different character
belonging either to the Company or to any third person, shall be marked as WGL's
property, and shall be stored in an area in the Company's facilities separate
from and not mingled with other goods of the Company or of any third person.

            (c) The Company shall inspect all Batteries (including the
Consignment Batteries) and notify WGL within one month if any of the Batteries
fail to meet the Company's specifications and quality standards for such
Batteries.

            (d) The Company shall comply with all laws which might in any way
affect WGL's ownership of the Consignment Batteries from time to time stored in
the Company's facility(s) and shall indemnify and hold harmless WGL from and
against all loss, damage, and expense arising out of any levy, attachment, lien
or process involving the Consignment Batteries. The Company shall be responsible
for, and shall indemnify WGL against, any loss or shrinkage in the quantity of
the Consignment Batteries while so stored, whether such loss or shrinkage is
caused by theft or pilferage or by fire, flood, tornado or other similar

                                     Page 5
<PAGE>

catastrophe. The Company shall purchase and maintain insurance covering all such
losses and naming WGL as additional insured.

            (e) The Company shall keep at all times a complete list or inventory
of the Consignment Batteries so stored, copies of which list shall be furnished
to WGL upon request. Upon not less than three (3) business days prior notice,
WGL's representatives shall have reasonable access to the Consignment Batteries
at the Company's facilities for the purpose of verifying such lists or
inspecting the condition of Consignment Batteries.

            (f) All public charges, whether in the nature of sales, occupational
or other taxes or assessment or license fees, which shall be levied or assessed
against the Consignment Batteries at the Company's facilities, or against the
Company or WGL by reason hereof, by any federal, state or municipal authority,
shall be paid by the Company.

            (g) All Consignment Products shall remain the property of WGL and
shall be held by the Company as such until withdrawn from the consigned stock
and purchased by the Company pursuant to this Agreement. The Company will
withdraw Batteries from the inventory of Consignment Batteries on a
first-in-first-out basis for each Battery model.

            (h) From time to time, as the Company shall purchase Batteries from
WGL, it may withdraw the Consignment Batteries so purchased from WGL's consigned
stock of the products at the Company's facility(s). Upon each such withdrawal
for purchase by the Company pursuant to this Agreement, title to the Consignment
Batteries so withdrawn shall pass to the Company.

            (i) Upon expiration of this Agreement or in the event that this
Agreement shall be terminated by the Company or WGL for any reason whatsoever,
the Company shall purchase, or be deemed to have purchased from WGL, all of the
remaining Consignment Batteries located at a Company facility, which met the
Company's specifications and quality standards at the time of receipt, as of the
date of expiration or termination, at the prices in effect at such time. Payment
shall be made in accordance with Section 2.4.

            (j) In the event that the Company changes the model mix of the
Batteries which it requires, the Company agrees to purchase, within six (6)
months, all units of Consignment Batteries which are no longer required by the
Company.

            2.6 Changes by WGL. WGL will not change the form, fit, or function
of any Battery supplied to the Company without prior written notice.

            2.7 Failure to Deliver Requirements.

                                     Page 6
<PAGE>

            (a) If WGL is unable for any reason to deliver sufficient quantities
of Batteries meeting the Company's specifications and quality standards to the
Company to meet its requirements therefor which are set forth in the firm
purchase order forecasts delivered pursuant to this Agreement, whether through
replenishment of Consignment Batteries or otherwise, for a period of three (3)
months, the Company shall have the right to purchase Batteries from third
parties, including pursuant to a supply agreement with a third party for up to a
one (1) year period if such a commitment is reasonably necessary in order for
the Company to obtain Batteries from a third party; provided, however, that,
upon the expiration of any such supply agreement or if Company does not enter
into a binding supply agreement, as soon as the Company is able to deliver the
Company's requirements, the Company shall resume purchasing its requirements of
Batteries from WGL.

            (b) In the event of fire, explosion, strikes, war, act of any
governmental agency, material or labor shortage, transportation contingency, act
of God or any other causes beyond the control of WGL ("Force Majeure"), WGL
shall not be liable for any delay in shipment or non-delivery of Batteries
covered by this Agreement arising from Force Majeure, and the Company shall be
bound to accept the delayed shipment or delivery made within a reasonable time.
In the event of Force Majeure, the Company shall be excused for the failure to
take and pay for Batteries ordered under this Agreement, until such Force
Majeure condition is removed. In the event such conditions cannot be corrected
by the party affected within six (6) months of the date of the occurrence of a
Force Majeure event, then the other party shall have the option to terminate
this Agreement upon one (1) month prior notice.

            2.8 Price Adjustment.

            (a) If the Company shall not comply with the provisions of Article
3, then WGL shall have the right to increase the prices for all Batteries upon
three (3) months prior notice. If the Company shall not accept any such new
"pricing" for Batteries, then WGL shall have the option and right to terminate
this Agreement upon not less than thirty (30) days prior notice. WGL agrees that
the rights specified in this Section 2.8(a) shall be WGL's sole remedy if the
Company does not comply with the provisions of Article 3 of this Agreement.

            (b) The prices for Batteries provided for in this Article 2 are
subject to upward modification, from time to time, by WGL during the period
which commences after December 31, 1998 if WGL incurs a Battery Cost Increase.
For purposes of this Section 3.4, the term "Battery Cost Increase" shall mean an
increase by * or more in WGL's 1998 standard product cost for one or more of the
Relevant Cost Factors listed in Section 1.8 above. The amount of any such
permitted price increase for a Battery due to a

                                     Page 7
<PAGE>

Battery Cost Increase shall be determined as follows:

            (i) In the case of Raw Material Costs, an amount equal to * times
the amount of such Battery Cost Increase.

            (ii) In the case of Regulatory Costs, it shall be * to the amount of
any such Battery Cost Increase; and

            (iii) In the case of New Design Costs, it shall be an amount equal *
the amount of such Battery Cost Increase.

            (c) If after any increase in a price for a Battery due to a Battery
Cost Increase, there occurs a decrease of * or more over WGL's standard product
costs (as adjusted by any such prior Battery Cost Increase) for such Battery for
one or more of the Relevant Cost Factors listed in Section 1.8 above ("Battery
Cost Decrease"), then WGL shall reduce the adjusted price for such Battery in
the same manner and proportion as provided for in Section 2.8(b) for Battery
Cost Increases; provided, however, that in no event shall the price for
Batteries be reduced below the prices set forth in Section 2.2.

            (d) If WGL is entitled and determines to impose a price increase
under Paragraph (c) of this Section 2.8, WGL shall give not less than three (3)
months written notice thereof in order that the forecasts provided for in
Section 2.3 to be made by the Company can take into account any such price
increase. WGL may not impose a price increase during the permitted period under
Paragraph (b) of this Section 2.3 more frequently than once every Contract Year.
WGL shall at the Company's written request make available appropriate records
substantiating the basis for its determination that a Battery Cost Increase has
occurred, or any Battery Cost Decrease, for audit at the Company's expense by an
independent certified public accounting representative to verify the accuracy of
the reports provided to the Company. Such representative shall execute a
suitable confidentiality agreement reasonably satisfactory to WGL prior to
conducting such audit. Such representative may disclose to the Company only its
conclusions regarding the accuracy and completeness of such reports, and shall
not disclose Confidential Information of WGL to the Company without the prior
written consent of WGL. Any such request for an audit must be made by the
Company within six months after any announced price increase under Paragraph
(b) of this Section 2.3 or any announced price decrease under Paragraph (c) of
this Section 2.3.

            (e) Prior to imposing any increase in the price of Batteries due to
a Battery Cost Increase for Raw Materials Costs, WGL shall allow the Company's
purchasing department a period of one (1) month after the price increase notice
referred to in Section

                                     Page 8
<PAGE>

2.8(d) to find alternative, qualified sources for any raw materials at a lower
cost than those determined by WGL, and WGL shall be obligated to buy from any
such lower cost sources before imposing any increase in the price of a Battery.

            2.9 WGL Warranty. WGL warrants that the Batteries delivered to the
Company will be free from defects in materials and workmanship at the time of
sale. WGL's sole obligation under this warranty is the replacement of any
Battery which is defective without charge. SELLER MAKES NO OTHER WARRANTY WITH
RESPECT TO THE BATTERIES, WRITTEN OR ORAL, EXPRESS, IMPLIED OR STATUTORY,
INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.
THE COMPANY EXPRESSLY ASSUMES ALL LIABILITY ARISING FROM OR IN CONNECTION WITH
THE USE OF THE BATTERIES PURCHASED HEREUNDER, WHETHER BASED ON CONTRACT,
WARRANTY, TORT OR OTHERWISE AND AGREES TO HOLD WGL HARMLESS FROM SUCH CLAIMS.

                             3. NON-HYBRID PRODUCTS.

            3.1 Product Development. Subject to all of the terms and conditions
of this Agreement, the Company has agreed to purchase Non-Hybrid Products which
meet the Company's specifications and quality standards, and the pricing
guidelines contained in Section 3.3 below from WGL. The Company and WGL
acknowledge and agree that WGL is not manufacturing or assembling any Non-Hybrid
Products at the present time for the Company and that WGL must complete its
design, tooling, plans and production lines for Non-Hybrid Products, and must
qualify such products with the Company, prior to any purchases of such products
by the Company from WGL. The Company agrees to provide WGL with all
qualification protocols and requirements, plans, designs, specifications,
drawings and other information in the Company's possession as reasonably
requested by WGL ("Qualification and Design Data") which may be necessary or
advisable in order for WGL to be able to manufacture Non-Hybrid Products for the
Company and to cooperate with WGL in connection with WGL's efforts to qualify
Non-Hybrid Products for Company purchase and use. Representatives of the Company
and WGL who have authority to make decisions including, but not limited to, in
the case of the Company, decisions with respect to qualification and purchasing,
shall meet not less frequently than once every three (3) months to discuss WGL's
progress in becoming qualified to supply Non-Hybrid Products to the Company and
any issue which then may exist with respect to WGL's qualification efforts
("Progress Meetings"). If either the Company or WGL believes at any time that
the other party is not fulfilling its obligations under this Article 3 with
respect to qualification, it can request a meeting with the other party, upon
reasonable notice, to discuss any issues or

                                     Page 9
<PAGE>

problems in that regard.

            3.2 Purchase Commitment. Upon execution and delivery of this
Agreement, the Company will provide WGL with * in purchase orders for Non-Hybrid
Products each of which WGL reasonably believes that WGL can qualify and deliver
during calendar years 1997-1998, a copy of which is attached hereto as
Attachment C. The Company further agrees that during the term of this Agreement
the Company will provide WGL with purchase orders for not less than (a) *
(calculated by dollar cost) of the Company's requirements for each such
Non-Hybrid Product in the twelve (12) months beginning with the month following
the first date of qualification of each such Non-Hybrid Product by WGL in
accordance with the Company's specifications and quality standards ("Initial
12-Month Period"); and (b) * (calculated by dollar cost) of the Company's
requirements for each such Non-Hybrid Product after the Initial 12-Month Period.
Subject to the other conditions of this Article 3, the Company shall be deemed
to be in compliance with the purchase commitment requirements for Non-Hybrid
Products of this Section 3.2 immediately upon the delivery to WGL of such
purchase orders. Subject to the other provisions of this Article 3, the Company
will not be deemed to be out of compliance with its purchase commitment due to
failure of WGL to qualify any Non-Hybrid Product or to meet the pricing
guidelines contained in Section 3.3 below, or to deliver any Non-Hybrid Products
as covered by Section 3.10(d) below. Following any failure of WGL to qualify any
such Non-Hybrid Product within six months after the Target Date For
Qualification for such product, or to meet the pricing guidelines contained in
Section 3.3 for any Non-Hybrid Product available to the Company from other
qualified vendors, the Company shall have the right to place purchase orders
with other qualified vendors for a sufficient quantity of such Non-Hybrid
Product to satisfy its requirements for a period not to exceed twelve (12)
months. During this 12-month period or thereafter, if WGL successfully qualifies
such Non-Hybrid Product, the Company will provide WGL with purchase orders for
delivery after the 12-month period for not less than * (calculated by dollar
cost) of the Company's yearly requirements for such Non-Hybrid Product, as
specified in (a) above. For purposes hereof, the term Target Date For
Qualification shall mean the date for each separate Non-Hybrid Product which
shall be specified in writing by WGL, when the Company issues its qualification
order, subject to the Company's approval, which shall not be unreasonably
withheld.

            3.3 Pricing.

            (a) Base Prices. "Base Prices" for Non-Hybrid Products shall mean
the prices charged to the Company by WGL for Non-Hybrid Products, exclusive of
tooling, shipping, and delivery charges. The Base Prices for certain Non-Hybrid
Products are set forth on Attachment A which may be amended from time to time in
a written instrument

                                    Page 10
<PAGE>

signed by authorized representatives of both parties to add additional
Non-Hybrid Products to Attachment A. - Except for the price adjustments provided
for in Section 3.4 below, pricing for the Non-Hybrid Products on Attachment A
will remain fixed for the term of this Agreement. Base Prices for Non-Hybrid
products not initially included in Attachment A which the Company is currently
purchasing shall be fixed for the term of this Agreement at the average
historical price that the Company has paid for each such Non-Hybrid Product
during 1997. Subject to Section 3.4, Base Prices for newly designed Non-Hybrid
products will be fixed for the term of this Agreement at the lower of (a) WGL's
pricing, or (b) the average of the pricing available to the Company from two
other qualified vendors.

            (b) Tooling charges, which are over and above the Base Prices listed
in Attachment A, shall be determined prior to or at the time WGL qualifies a
Non-Hybrid Product. WGL may charge the Company tooling charges covering the
entire cost of tooling for "L" Connector Assemblies and for Case Halves, but not
for any other Non-Hybrid Products which the Company is currently purchasing from
other vendors. To the extent that Company-owned tooling at the Company's current
vendors (i) is in usable condition, (ii) is compatible with WGL's manufacturing
machinery and (iii) can be transferred from the Company's current vendors. WGL
shall, at its reasonable discretion, use such tooling rather than purchasing new
tooling. Tooling charges may be charged by WGL for any new Non-Hybrid Product
that it qualifies, but not for any new Non-Hybrid Product that it fails to
qualify.

            3.4 Permitted Price Adjustments.

            (a) The Base Prices for Non-Hybrid Products provided for in this
Article 3 are subject to increase, from time to time, by WGL if WGL, incurs a
Non-Hybrid Cost Increase except that, in the case of changes in Raw Material
Costs (other than costs related to precious metal, no such increase can be made
prior to the second anniversary of the Effective Date. For purposes of this
Section 3.5, the term "Non-Hybrid Cost Increase" shall mean an increase by * or
more in WGL's standard product costs for one or more of the Relevant Cost
Factors listed in Section 1.8 above (other than Raw Material Cost changes
related to precious metals), determined as of the date WGL shall have qualified
such product for sale to the Company. The amount of any such permitted price
increase due to a Non-Hybrid Cost Increase shall be determined as follows:

            (i) In the case of Raw Material Costs other than costs related to
precious metals, it shall be an amount equal to * times the amount of such
Non-Hybrid Cost Increase.

                                    Page 11
<PAGE>

            (ii) In the case of Regulatory Costs, it shall be an amount * the
amount of the Non-Hybrid Cost Increase.

            (iii) In the case of New Design Costs, it shall be an amount equal *
the amount of the Non-Hybrid Cost Increase.

If the cost of precious metals included in any Non-Hybrid Product increases or
decreases from the Base Cost, then the Base Price for such Non-Hybrid Product
will be increased or decreased, as the case may be by an amount equal * times
the change in the Base Cost. Any such change may be made at any time during the
term of this Agreement but not more frequently than once every two months. For
purposes hereof, the "Base Cost" shall mean the price of the precious metal on
the date of this Agreement as reported in the Wall Street Journal; and changes
in the Base Cost for any precious metal shall be determined by changes in the
prices for the metal as reported in the Wall Street Journal.

            (b) If after any increase in a price for a Non-Hybrid Product due to
a Non-Hybrid Cost Increase, there occurs a decrease of * or more over WGL's
standard product costs (as adjusted by any such prior Non-Hybrid Cost Increase)
for such Non-Hybnd Product for one or more of the Relevant Cost Factors listed
in Section 1.8 above ("Non-Hybrid Cost Decrease"), then WGL shall reduce the
adjusted price for such Non-Hybrid Product in the same manner and proportion as
provided for in Section 3.4(a) for Non-Hybrid Cost Increases; provided, however,
that in no event shall the price for any such Non-Hybrid Product be reduced
below the Base Price for such Non-Hybrid Product.

            (c) If WGL is entitled and determines to impose a price increase
under this Section 3.4, WGL shall give not less than three months' written
notice thereof. For Non-Hybrid Products other than those fabricated from
precious metals, WGL may not impose a price increase more frequently than once
every six (6) months. The prices for Non-Hybrid Products fabricated from
precious metals may be increased more frequently as provided for in Section
3.4(a). WGL shall deliver to the Company together with the notice provided for
herein a written report which describes in reasonable detail the basis for WGL's
determination that a price increase is permitted under this Section 3.4. WGL
shall at the Company's written request make available appropriate records
substantiating the basis for its determination that a Non-Hybrid Cost Increase
has occurred, or any Non-Hybrid Cost Decrease, for audit at the Company's
expense by an independent certified public accounting representative to verify
the accuracy of the reports provided to the Company. Such representative shall
execute a suitable confidentiality agreement reasonably satisfactory to WGL
prior to conducting such audit. Such representative may disclose to the Company
only its conclusions regarding the accuracy and completeness of such reports,
and shall not disclose Confidential Information of WGL to the Company without
the prior written consent

                                    Page 12
<PAGE>

of WGL. Any such request for an audit must be made by the Company within six (6)
months of any announced price increase hereunder.

            (d) Prior to imposing any increase in the price of Non-Hybrid
Products due to a Non-Hybrid Cost Increase for Raw Material Costs, WGL shall
allow the Company's purchasing department a period one (1) month after the price
increase notice referred to in Section 2.8(d) to find alternative, qualified
sources for any raw materials at a lower cost than those determined by WGL, and
WGL shall be obligated to buy from any such lower cost sources before imposing
any increase in the price of a Non-Hybrid Product.

            3.5 Additional Non-Hybrid Products. The Company agrees that it will
notify WGL of all Non-Hybrid Products for new and existing models of its
implantable medical devices, or modifications of existing models, which are not
Micro-Electronic Components. In connection therewith, at WGL's request, the
Company will provide WGL with Qualification and Design Data for each such new
and existing Non-Hybrid Product and cooperate with WGL in connection with WGL's
efforts to qualify for the supply of such Non-Hybnd Product to the Company,
including participation in Progress Meetings. The Company and WGL agree that
Attachment A will be amended in writing, from time to time as specified in
Section 3.3 above, to reflect all such additions.

            3.6 License. The Company hereby grants WGL a license or sublicense
(as applicable) to use any and all Qualification and Design Data, and all
patents, copyrights and know-how which the Company owns, or which it has the
right to use and sublicense, which cover Non-Hybrid Products, solely in
connection with WGL's manufacture and supply of Non-Hybrid Products to the
Company. This license shall permit WGL to subcontract out the manufacture the
production of Non-Hybrid Products.

            3.7 Estimated Annual Usage.

            (a) "Estimated Annual Usage" as used herein shall mean the
quantities of Non-Hybrid Products which the Company estimates as its needs for
Non-Hybrid Products from WGL for the ensuing twelve (12) month period and will
be subject to the minimum purchase quantities specifed in Section 3.2 above.
Initial Estimated Annual Usages for each of the initial Non-Hybrid Products
shall be specified in Attachment A. As additions are made to the Non-Hybrid
Products specified in Attachment A as provided in Section 3.3 above, the Company
shall provide written notice as to the initial Estimated Annual Usage for each
Non-Hybrid Product so added at the time of addition to the Non-Hybrid Products
specified in Attachment A.

            (b) As soon as practicable after WGL qualifies a Non-Hybrid Product
as

                                    Page 13
<PAGE>

contemplated by this Article 3, the Company will provide WGL with its Estimated
Annual Usage for that Non-Hybrid Product, and will provide WGL with a twelve
(12) months forecast stating anticipated needs. This forecast will provide WGL
with a total of twelve (12) months projected requirements for planning purposes.
Such forecast will be updated each succeeding calendar quarter.

            (c) WGL shall not be required to manufacture more than * of the
Company's twelve (12) month Estimated Annual Usage of a Non-Hybrid Product in
any one three (3) month period, except upon not less than a three (3) month
prior written notice. The sole exception to this provision shall be if WGL has
fallen behind on past deliveries due to its own fault, in which case WGL shall
be required to manufacture and deliver each month up to * more than the average
monthly quantities which were scheduled for the preceding three-month period
until WGL is back on schedule with its deliveries.

            3.8 Supplier Inventory. "Supplier Inventory" shall mean those
quantities of Non-Hybrid Products which WGL is required by this Agreement to
maintain. The levels of Supplier Inventory for each of the Non-Hybrid Products
shall not exceed twenty-five percent (25%), and the specific level for each
Non-Hybrid Product shall be as specified in Attachment A. WGL must be capable of
shipping its entire Supplier Inventory of any and/or all Non-Hybrid Products to
the Company as finished goods within a period of not less than seven (7) nor
more than twenty-one (21) days. The specific period which is applicable for each
Non-Hybrid Product shall be as specified in Attachment A.

            3.9 Maintenance of Supplier Inventory by WGL.

            (a) Build-Up of Supplier Inventory. It is recognized by the parties
that at the outset of this Agreement, or at the time new Non-Hybrid Products are
added to this Agreement, WGL may not have sufficient Supplier Inventory to meet
the requirements of this Agreement. WGL agrees that within a period of not more
than three (3) months from the date of qualification of each Non-Hybrid Product
it shall possess sufficient Supplier Inventory to meet the requirements of this
Agreement as to all Non-Hybrid Products included in this Agreement at the date
of execution of the Agreement. WGL further agrees that within a period of not
more than three (3) months from the date of qualification of any new Non-Hybrid
Product(s) under this Agreement, WGL shall possess sufficient Supplier Inventory
to meet the requirements of this Agreement as to those Non-Hybrid Products added
to this Agreement. When Company provides WGL with an update in Company's
Estimated Annual Usage for one or more of the Products specified in Attachment A
as provided in Section 3.7 above, and when Estimated Annual Usage for any
Non-Hybrid Product has increased from a previous Estimated Annual Usage, WGL
agrees to use its best efforts to increase the level of Supplier Inventory for
the affected Non-Hybrid Product(s) within a

                                    Page 14
<PAGE>

period of forty (40) days from the date that Company notifies WGL of the
increase in Company's Estimated Annual Usage for the affected Non-Hybrid
Product(s).

            (b) Agreement by WGL to Maintain Supplier Inventory. During the Term
of this Agreement, and subject to the limitations of Sections 3.9(a) above and
3.9(c) below. WGL agrees to maintain sufficient Supplier Inventories of the
Non-Hybrid Products to meet the requirements of this Agreement.

            (c) Replenishment of Supplier Inventory. In the event that the
Supplier Inventories of any or all of the Non-Hybrid Products are totally
depleted, WGL agrees to use its best efforts to replenish the Supplier
Inventories within a period of forty (40) days.

            (d) Reductions in Supplier Inventories. When the Company provides
WGL with an update in Company's Estimated Annual Usage for one or more of the
Non-Hybrid Products specified in Attachment A, as provided in Section 3.7 above,
and when the Estimated Annual Usage for any Non-Hybrid Product(s) has dropped
from a previous Estimated Annual Usage, WGL agrees to reduce the level of
Supplier Inventory for the affected Product(s) by not rebuilding inventory as it
is provided to the Company until the level of Supplier Inventory for the
affected Non-Hybrid Product(s) drops to the most recent Estimated Annual Usage
level. Within one month after the end of each Contract Year, WGL shall review
the level of Supplier Inventory of each Non-Hybrid Product then maintained by
WGL. If based on the Company's actual usage of any Non-Hybrid Product in such
prior Contract Year, WGL is holding Supplier Inventory of any Non-Hybrid Product
in excess of the level required for such Non-Hybrid Product, the Company, at
WGL's request, shall take delivery and purchase any such excess Supplier
Inventory of that Non-Hybrid Product within two months after the end of such
Contract Year.

            (e) Location of Non-Hybrid Product Inventories. WGL agrees to
maintain the Supplier Inventories of the Non-Hybrid Products in the Clarence, NY
area from which the Supplier Inventories of the Non-Hybrid Products can be
shipped within the seven (7) to twenty-one (21) working day period as specified
in Section 3.8 above.

            (f) Delivery of the Non-Hybrid Products. WGL agrees to properly
manage its supplies of raw materials, work-in-progress, and finished goods in
order to ensure that it will be capable of shipping the entire Supplier
Inventory as finished goods within the seven (7) to twenty-one (21) working day
period as specified in Section 3.7 above, except and only to the extent that WGL
is delayed in shipping a portion of the Non-Hybrid Products in the Supplier
Inventories due to WGL being in the process of building or timely renewing the
Supplier Inventories of the Products pursuant to Sections 3.9(a) and 3.9(c)
above.

                                    Page 15

            3.10 Purchase of Non-Hybrid Products by the Company.

            (a) Orders: Non-Hybrid Products shall be ordered by the Company from
WGL with purchase orders issued from time to time by the Company. Acceptance by
WGL of such purchase orders submitted by the Company shall create a contract for
sale and purchase on the terms and conditions contained in this Agreement.

            (b) Purchase of Supplier Inventories. Upon expiration of this
Agreement or in the event that this Agreement shall be terminated by the Company
or WGL for any reason whatsoever, the Company agrees to purchase the Supplier
Inventories of the Non-Hybrid Products from WGL to the extent that WGL is in
compliance with the terms of this Agreement governing the levels of the Supplier
Inventories. The Company will not be required to purchase excess inventories
from WGL to the extent that such inventories exceed the most recent level of
Estimated Annual Usage provided by the Company, except and only to the extent
that the excess inventory was due to reduction(s) in the Estimated Annual Usage
levels provided by the Company without sufficient intervening purchases by the
Company to allow the levels of the Supplier Inventories to drop to the most
recent Estimated Annual Usage levels.

            (c) Option to Purchase Supplier Inventories As Is. At the Company's
option, WGL will supply the Supplier Inventories of Non-Hybrid Products to the
Company either as finished goods within one (1) month after termination of the
Agreement, or as the combination of raw materials, work-in-progress, and/or
finished goods remaining upon termination of the Agreement within one (1) month
after of termination of the Agreement. The parties shall negotiate prices to be
paid by the Company to WGL for Non-Hybrid Products which are work-in-progress or
in raw material form.

            (d) Failure to Deliver:

                  (i) If WGL is unable for any reason, and other than as
provided for in Paragraph (iii) of this Section 3.10(d), to deliver sufficient
quantities of any Non-Hybrid Product meeting the Company's specifications and
quality standards to the Company to meet its requirements therefore which are
set forth in the firm purchase order forecasts delivered pursuant to this
Agreement, and WGL is not able to remedy this situation for a period of three
(3) months, the Company shall have the right to place purchase orders with other
qualified vendors for sufficient quantity of such Non-Hybrid Product to satisfy
its requirements for a period not to exceed six (6) months, except that with
respect to the following categories of Non-Hybrid Products the time period may
be up to twelve (12) months: (A) feed-throughs, (B) Ti Nitrate machined parts,
(C) L-connector assemblies and (D) case halves having an annual requirement of *
units or less. After the applicable

                                    Page 16
<PAGE>

period, if WGL successfully re-establishes its ability to deliver such
Non-Hybrid Product, the Company will resume purchasing such Non-Hybrid Product
from WGL at the rate specified in Section 3.2 above, i.e., at a forty percent
(40%) rate if the supply disruption occurs during the first year after initial
qualification, or at an eighty percent (80%) rate if the supply disruption
occurs during the second or subsequent years after initial qualification of such
Non-Hybrid Product.

                  (ii) In the event of Force Majeure, WGL shall not be liable
for any delay in shipment or non-delivery of Non-Hybrid Products covered by this
Agreement arising from Force Majeure, and the Company shall be bound to accept
the delayed shipment or delivery made within a reasonable time. In the event of
Force Majeure, the Company shall be excused for the failure to take and pay for
Non-Hybrid Products ordered under this Agreement, until such Force Majeure
condition is removed. In the event such conditions cannot be corrected by the
party affected within six (6) months of the date of the occurrence of a Force
Majeure event, then the other party shall have the option to terminate this
Agreement upon one (1) month prior notice.

                  (iii) If the Company (A) rejects or refuses to accept any
Non-Hybrid Product from WGL on the basis of quality, failure to meet or maintain
then current product specifications or qualification standards, or some other
similar or comparable reason and (B) would otherwise purchase a Non-Hybrid
Product from one or more third parties in amounts which would result in the
Company not satisfying the applicable quota set forth in Section 3.2, then the
Company shall send WGL a written notice which sets forth (1) the product
involved and (2) the basis upon which it has determined that WGL is not
satisfactorily delivering the Company's requirements of the Non-Hybrid Product
at issue ("Non-Delivery Notice"). At WGL's written request, the Company agrees
to provide one or more senior managers of the Company to meet with
representatives of WGL to review the reasons set forth in the Company's
Non-Delivery Notice, and to discuss and, if practicable, establish an action
plan to correct any deficiency or failure by WGL in order that the Company shall
purchase or resume purchasing Non-Hybrid Products.

                           4. NON-HYBRID GENERAL TERMS

            4.1 Delivery. WGL shall deliver Non-Hybrid Products to the Company's
facility at Valley View Court in Sylmar, California, and/or to such other

If the Company elects to cancel or rescind such purchase, WGL shall promptly
refund and reimburse the Company the price paid by the Company for such
purchase, including freight and shipping costs incurred by the Company in such
purchase, prior to the return of the same to WGL. If the Company elects to have

shall furnish the Company with copies of any Form 483 report and Establishment
Inspection Reports to the extent that they apply to any product.

            4.6 Violation of Law. The Company and WGL shall each strictly
observe and comply with all federal and local laws and regulations which may
govern the manufacture, sale, handling and disposal of any Non-Hybrid Products
herein specified. Violation of any such law or regulation may be viewed as a
breach of this Agreement, and may be cause for termination or suspension of
sales hereunder. Nothing herein shall be construed to allow either party the
right to cancel this Agreement for any inadvertent error or minor violation of
any law or regulation by the other party.

            4.7 Inspection and Acceptance. WGL shall perform testing to ensure
that the Non-Hybrid Products meet all applicable specifications. The Company

<PAGE>

            (b) This Warranty does not apply to depletion, wear and/or any
failure occurring as a result of any of the following: normal use, abuse,
misuse, any alteration or modification made to any Non-Hybrid Product without
the express written consent of WGL, attempted disassembly, neglect, improper
installation, or any other use inconsistent with any applicable law, rule,
regulation or governmental directive, or any use inconsistent with the
specifications or warning or recommended operating practices specific to the
Non-Hybrid Product.

            (c) THE WARRANTY SET FORTH IN THIS SECTION 4.9 IS IN LIEU OF ALL
OTHER WARRANTIES (EXCEPT OF TITLE), EXPRESSED, IMPLIED OR STATUTORY, INCLUDING
ANY WARRANTY OF MERCHANTABILITY OR OF FITNESS FOR A PARTICULAR PURPOSE.

                              5. ASSEMBLY OPERATION

            5.1 Phoenix Site. Subject to the terms and conditions of this
Agreement, WGL presently intends to establish an assembly facility in the
Phoenix, Arizona area to provide pre-assembly of Non-Hybrid Products to be
supplied by WGL to the Company, and any components to be supplied by other
vendors, up to the point of integration with the Company's hybrid circuitry. WGL
shall not finalize its plans for an assembly facility in the Phoenix area until
WGL and the Company shall have agreed in writing upon the level of assembly work
and annual volume requirements, which agreement is a precondition to WGL's
establishment of such a facility. If the parties do so agree that WGL shall do
assembly for the Company, WGL will establish a Phoenix assembly facility and, in
such event, the parties will renegotiate the Supplier Inventory requirements set
forth in Article 3.

            5.2 Pricing. The parties agree to negotiate in good faith the amount
which WGL will charge for such assembly.

            5.3 Timing. The parties anticipate that WGL would establish its
Phoenix facility when it has qualified and has begun to produce a substantial
amount of the non-hybrid components for the Company implantable medial devices,
but, in any event, no later than December 31, 1999.

            5.4 Limitation. This Section 5 is written merely as a statement of
the intentions of the parties, and the parties do not intend to be legally bound
by it. The full terms and conditions of this subassembly manufacturing
arrangement shall be contained in a separate agreement which will be negotiated
between the parties. Upon execution of that

                                    Page 20
<PAGE>

agreement, the parties will become legally bound under the terms and conditions
of that agreement.

                6. LIMITATION OF LIABILITY; COMPLIANCE WITH LAW.

            6.1 LIMITATION OF LIABILITY. THE REMEDIES OF THE COMPANY IN THE
WARRANTY SET FORTH IN SECTION 2.9 WITH RESPECT TO BATTERIES AND IN THE WARRANTY
SET FORTH IN SECTION 4.9 WITH RESPECT TO NON-HYBRID PRODUCTS ARE EXCLUSIVE, AND

SOLD TO THE COMPANY, IN CONNECTION WITH THE PERFORMANCE THEREOF, OR FROM THE
SALE, DELIVERY, INSTALLATION OR REPAIR COVERED BY OR FURNISHED UNDER ANY SALE TO
THE COMPANY WHETHER BASED ON CONTRACT, WARRANTY, NEGLIGENCE, INDEMNITY, STRICT
LIABILITY, OR OTHERWISE SHALL NOT EXCEED THE PURCHASE PRICE OF THE PRODUCT UPON
WHICH SUCH LIABILITY IS PLACED. WGL SHALL IN NO EVENT BE LIABLE TO THE COMPANY,
OR TO ANY SUCCESSOR IN INTEREST OR ANY BENEFICIARY OR ASSIGNEE THEREOF, RELATING

            6.2 FDA Compliance. During the term of this Agreement the Company
shall have responsibility for obtaining at its expense, in its name and at its
discretion any necessary device regulatory approvals from the U.S. Food and Drug
Administration (i.e. PMA's or 501 (k)'s as the case may be), and applicable
regulatory agencies of such other countries in which product incorporating the
Batteries or Non-Hybrid Products will be sold. WGL shall supply the Company with
all documents, instruments, information, reports and advice and general
assistance as is necessary to complete, and as is reasonably requested by the
Company in connection with such regulatory approval efforts.

            6.3 WGL Compliance. WGL shall be responsible for compliance with
present and future applicable statutes, laws, ordinances and regulations of
United States and

                                    Page 21

                  8. COMPANY AFFILIATES; NO OTHER BENEFICIARIES

            8.1 Company Affiliates. The Company hereby represents and warrants
to WGL that it has the power, authority and approval to bind its Affiliates to
the provisions of Articles 2 and 3 of this Agreement with respect to the
purchase of their requirements for Batteries and Non-Hybrid Products. The
Company hereby acknowledges that WGL has agreed to the pricing for the Batteries
and Non-Hybrid Products in reliance upon the foregoing representatives and
warranties of the Company.

            8.2 No Other Beneficiaries. Except as provided for in Section 6.1,
nothing in this Agreement, expressed or implied, is intended to confer on any
person other than the parties to this Agreement or their respective successors
or assigns, any rights, remedies, obligations or liabilities under or by reason
of this Agreement.

                               9. CONFIDENTIALITY

            9.1 Treatment of Propriety Information. Each of WGL and the Company
(each a "receiving party") agrees to maintain all proprietary information
disclosed by the other party to this Agreement (each a "disclosing party") in
strict secrecy and confidence, and not to disclose such proprietary information
to any third party, nor make any use of such information and technology for its
own benefit or gain other than in carrying out its efforts under this Agreement.
The receiving party agrees to have its employees sign agreements, or to have an
appropriate corporate policy in effect, which requires them to keep confidential
any proprietary information they learn in their positions at the receiving
party; these agreements and/or policies shall require them to maintain
confidentiality of proprietary information disclosed by the disclosing party.
The receiving party further agrees that no proprietary information or materials
will be supplied to any other corporation, partnership, laboratory, or
individuals other than those approved in writing by the disclosing party, with
the exception of disclosure to the FDA and similar regulatory agencies of
information relative to obtaining regulatory approval.

            9.2 Limited Release. The receiving party shall be released from the
obligations of Section 9.1 to the extent that any of the disclosed information:
(a) was already part of the public domain at the time of the disclosure by the
disclosing party; (b) becomes part of the public domain through no fault of the
receiving party (but only after and only to the extent that it is published or
otherwise becomes part of the public domain); (c) was in the receiving party's
possession prior to the disclosure by the disclosing party and was not acquired,
directly, or indirectly, from the disclosing part or from a third party who was
under a continuing obligation of confidence to the disclosing party; (d) is
received (after the disclosure by the disclosing party) by the receiving party
from a third party who did not require the receiving party to hold it in
confidence and did not acquire it directly or indirectly, from the disclosing
party under a continuing obligation of

                                    Page 23
<PAGE>

confidence; or (e) is disclosed by the receiving party pursuant to judicial
compulsion, provided that the disclosing party is notified at the time such
judicial action is initiated. In addition, notwithstanding Section 9.1, WGL may
provide proprietary information of the Company to its subcontractors and vendors
without Company's prior approval provided that WGL first requires any such
subcontractor or vendor to sign a confidentiality agreement which requires them
to keep confidential such Company information and not to use it except for the
purpose of performing their obligations to WGL.

            9.3 Term of Obligation. The obligation of the receiving party to
receive and hold information disclosed by the disclosing party in confidence, as
required by this Section 8, shall terminate eight (8) years from the date of
disclosure of the information hereunder and shall survive any earlier
termination of this Agreement.

            9.4 Disposal Upon Termination. In the event this Agreement is
terminated, any samples, sketches, or other proprietary material provided by the
disclosing party to the receiving party shall be destroyed or returned to the
disclosing party, unless and to the extent such materials are necessary to the
receiving party to provide continuing support.

                                10. MISCELLANEOUS

            10.1 Relationship. This Agreement does not make either party the
employee, agent, legal representative or partner of the other for any purpose
whatsoever. Neither party is granted any right or authority to assume or to
create any obligation or responsibility, express or implied. on behalf of or in
the name of the other party. In fulfilling its obligations pursuant to this
Agreement, each party shall be acting as an independent contractor.

            10.2 Assignment. This Agreement shall inure to the benefit of and be
binding upon each of the parties hereto and their respective permitted
successors and assigns. It may not be voluntarily assigned in whole or in part
by either party without the prior written consent of the other; provided,
however, that a successor in interest by merger, by operation of law, purchase
or otherwise of the entire business of either party shall acquire all interest
of such party hereunder, and further provided that a party may assign this
Agreement to an Affiliate of such party (the patty to this Agreement who makes
any such assignment to an Affiliate shall, notwithstanding such assignment,
remain fully responsible for assuring, and for any failure to assure, prompt
performance by such Affiliate of all of such assigning party's obligations under
this Agreement). Any prohibited assignment shall be null and void.

            10.3 Entire Agreement. This Agreement constitutes the entire
agreement of the parties with respect to the subject matter hereof and
supersedes all previous proposals or agreements, oral or written, and all
negotiations, conversations or discussions heretofore had

                                    Page 24
<PAGE>

between the parties related to the subject matter of this Agreement. The pates
expressly agree that none of the terms and conditions of any standard preprinted
forms used by either WGL or the Company in effectuating the purchase and sale
transactions contemplated by this Agreement (including, but not limited to,
purchase orders, acknowledgements and acceptance forms, invoices, labels and
shipping documents) which are inconsistent with, or in addition to, those
contained in this Agreement shall have any force or effect.

            10.4 Governing Law. This Agreement shall be governed by, and
interpreted and construed in accordance with, the laws of the State of New York.

            10.5 Waiver, Discharge, etc. This Agreement may not be released,
discharged, abandoned, changed or modified in any manner, except by an
instrument in writing signed on behalf of each of the parties to this Agreement
by their duly authorized representatives. The failure of either party to enforce
at any time any of the provisions of this Agreement shall in no way be construed
to be a waiver of any such provision, nor in any way to affect the validity of
this Agreement or any part of it or the right of either party after any such
failure to enforce each and every such provision. No waiver of any breach of
this Agreement shall be held to be a waiver of any other or subsequent breach.

            10.6 Titles and Headings; Construction. The titles and headings to
Sections herein are inserted for the convenience of reference only and are not
intended to be a part of or to affect the meaning or interpretation of this
Agreement. This Agreement shall be construed without regard to any presumption
or other rule requiring construction hereof against the party causing this
Agreement to be drafted. When reference is made in this Agreement to a "month"
or to "months" (e.g., "three (3) months notice"), it shall mean a period
commencing on a specific day of a month (e.g., the 15th) and continuing to the
corresponding day of a later month (e.g., three (3) months from April 15 would
mean a period ending on the next succeeding July 15).

            10.7 Notices. All notices or other communications to a party
required or permitted hereunder shall be in writing and shall be delivered
personally, by courier or by telecopy (receipt confirmed) to such party (or, in
the case of an entity, to an executive officer of such party) or shall be given
by certified mail, postage prepaid with return receipt requested, addressed as
