                                   THE MERGER

     SECTION 1.1  The Merger.

     (a) Upon the terms and subject to the conditions of this Agreement, and in
accordance with the DGCL, at the Effective Time (as defined in Section 1.1(b),
Merger Sub shall be merged (the "Merger") with and into the Company, whereupon
the separate existence of Merger Sub shall cease, and the Company shall continue
as the surviving corporation (sometimes referred to herein as the "Surviving
Corporation") and shall continue to be governed by the DGCL.

     (b) Concurrently with the Closing (as defined in Section 1.7 hereof), the
Company, Parent and Merger Sub shall cause a certificate of merger (the
"Certificate Of Merger") with respect to the Merger to be executed and filed
with the Secretary of State of the State of Delaware (the "Secretary Of State")
as provided in the DGCL and shall make all other filings or recordings required
by the DGCL in connection with the Merger. The Merger shall become effective on
the date and time at which the Certificate of Merger has been duly filed with
the Secretary of State or at such later date and time as is agreed between the
parties and specified in the Certificate of Merger, and such date and time is
hereinafter referred to as the "Effective Time."

     (c) The Merger shall have the effects set forth in the DGCL. Without
limiting the generality of the foregoing and subject thereto, from and after the
Effective Time, the Surviving Corporation shall possess all properties, rights,
privileges, immunities, powers and franchises and be subject to all of the
obligations, restrictions, disabilities, liabilities, debts and duties of the
Company and Merger Sub.

     SECTION 1.2  Effect On Common Stock. At the Effective Time:

          (a) Cancellation of Shares of Common Stock. Each share of Common Stock
     held by the Company as treasury stock and each share of Common Stock owned
     by Parent, Merger Sub or any direct or indirect wholly-owned subsidiary of
     Parent or the Company immediately prior to the Effective Time shall
     automatically be cancelled and cease to exist, and no consideration or
     payment shall be delivered

                                       A-1

     therefor or in respect thereto. All shares of Common Stock to be converted
     into the right to receive the Merger Consideration pursuant to this Section
     1.2 shall, by virtue of the Merger and without any action on the part of
     the holders thereof, cease to be outstanding, be cancelled and cease to
     exist, and each holder of a Certificate (as defined in Section 1.3(b))
     shall thereafter cease to have any rights with respect to such shares of
     Common Stock, except the right to receive the Merger Consideration into
     which such shares of Common Stock have been converted.

          (b) Conversion of Shares of Common Stock. Subject to Section 1.3(d)
     hereof, each share of Common Stock issued and outstanding immediately prior
     to the Effective Time (other than shares of Common Stock referred to in the
     first sentence of Section 1.2(a) hereof and Dissenting Shares (as defined
     in Section 1.2(c)) shall, by virtue of the Merger and without any action on
     the part of the holder thereof, be converted into the right to receive an
     amount of cash, without interest, equal to $48.00 (the "Merger
     Consideration").

          (c) Dissenting Shares.

             (i) Any shares of Common Stock held by a holder who has demanded
        and perfected appraisal rights for such shares in accordance with
        Section 262 of the DGCL and who, as of the Effective Time, has not
        effectively withdrawn or lost such appraisal rights ("Dissenting
        Shares") shall not be converted into or represent a right to receive
        Merger Consideration pursuant to Section 1.2(b), but the holder thereof
        shall only be entitled to such rights as are granted by the DGCL.

             (ii) Notwithstanding the provisions of subsection (i) above, if any
        holder of shares of Common Stock who demands appraisal of such shares
        under the DGCL shall effectively withdraw or lose (through failure to
        perfect or otherwise) such holder's appraisal rights, then, as of the
        later of (A) the Effective Time or (B) the occurrence of such event,
        such holder's shares of Common Stock shall automatically be converted
        into and represent only the right to receive Merger Consideration as
        provided in Section 1.2(b), without interest thereon, upon surrender of
        the Certificate representing such shares.

             (iii) The Company shall give Parent (A) prompt notice of its
        receipt of any written demands for appraisal of any shares of Common
        Stock, withdrawals of such demands, and any other instruments relating
        to the Merger served pursuant to the DGCL and received by the Company
        and (B) the opportunity to direct all negotiations and proceedings with
        respect to demands for appraisal of any shares of Common Stock under the
        DGCL. The Company shall not, except with the prior written consent of
        Parent or as may be required under applicable law (in which case Parent
        shall be consulted), voluntarily make any payment with respect to any
        demands for the appraisal of Common Stock or offer to settle or settle
        any such demands or approve any withdrawal of such demands.

          (d) Closing of the Company's Transfer Books. At the Effective Time,
     the stock transfer books of the Company shall be closed and no transfer of
     Common Stock shall thereafter be made. If, after the Effective Time,
     Certificates are presented to the Surviving Corporation, they shall be
     cancelled and exchanged for the Merger Consideration as provided in this
     Article I, subject to applicable law in the case of Dissenting Shares.

          (e) Conversion of Common Stock of Merger Sub. Each share of common
     stock of Merger Sub issued and outstanding immediately prior to the
     Effective Time shall be converted into one share of common stock of the
     Surviving Corporation with the same rights, powers and privileges as the
     shares so converted and shall constitute the only outstanding shares of
     capital stock of the Surviving Corporation.

     SECTION 1.3  Exchange Of Certificates.

     (a) Prior to the mailing of the Proxy Statement (as defined in Section 3.9
hereof) a bank, trust company or other person reasonably acceptable to the
Company shall be designated by Parent to act as the depositary and paying agent
for the delivery of the Merger Consideration in exchange for shares of Common
Stock (the "Paying Agent") in connection with the Merger. From time to time, as
necessary, at or following the Effective Time, Parent shall deposit, or cause to
be deposited, with the Paying Agent the amount needed to pay the

                                       A-2
   3

portion of the aggregate Merger Consideration for the benefit of the holders of
shares of Common Stock which are converted into the right to receive the Merger
Consideration pursuant to Section 1.2(b) hereof for which Certificates have been
surrendered or payment is otherwise due (the "Exchange Fund"). For purposes of
this Agreement, "person" means any natural person, firm, individual,
corporation, limited liability company, partnership, association, joint venture,
company, business trust, trust or any other entity or organization, whether
incorporated or unincorporated, including a government or political subdivision
or any agency or instrumentality thereof.

     (b) As of or promptly following the Effective Time, the Surviving
Corporation shall cause the Paying Agent to mail to each holder of record of a
certificate or certificates, which immediately prior to the Effective Time
represented outstanding shares of Common Stock (other than Dissenting Shares)
(the "Certificates"), (i) a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon proper delivery of the Certificates to the Paying Agent and
which shall be in the form and have such other provisions as Parent and the
Company may reasonably specify) and (ii) instructions for use in effecting the
surrender of the Certificates in exchange for the Merger Consideration into
which the number of shares of Common Stock previously represented by such
Certificate shall have been converted into the right to receive pursuant to this
Agreement. Upon surrender of a Certificate for cancellation to the Paying Agent,
together with a letter of transmittal duly completed and validly executed in
accordance with the instructions thereto, and such other documents as may
reasonably be required pursuant to such instructions, the holder of such
Certificate shall be entitled to receive in exchange therefor the Merger
Consideration for each share of Common Stock formerly represented by such
Certificate, to be distributed as soon as practicable after the Effective Time,
and the Certificate so surrendered shall be forthwith cancelled. The Paying
Agent shall accept such Certificates upon compliance with such reasonable terms
and conditions as the Paying Agent may impose to effect an orderly exchange
thereof in accordance with normal exchange practices.

     (c) Any portion of the Exchange Fund which remains undistributed to the
holders of Certificates for six months after the Effective Time shall be
delivered to Parent, upon demand, and any holders of shares of Common Stock
prior to the Merger who have not theretofore complied with this Article I shall
thereafter look for payment of their claim, as general creditors thereof, only
to Parent for their claim for Merger Consideration, without interest.

     (d) None of Parent, the Company or the Paying Agent shall be liable to any
person in respect of any Merger Consideration held in the Exchange Fund
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law. If any Certificates shall not have been surrendered
prior to one year after the Effective Time (or immediately prior to such earlier
date on which Merger Consideration in respect of such Certificate would
otherwise escheat to or become the property of any Governmental Entity (as
defined in Section 3.3(b) hereof)), any such Merger Consideration in respect of
such Certificate shall, to the extent permitted by applicable law, become the
property of Parent, free and clear of all claims or interest of any person
previously entitled thereto.

     SECTION 1.4  Transfer Taxes; Withholding. If any Merger Consideration is to
be remitted to a person other than the person in whose name the Certificate
surrendered in exchange therefor is registered, it shall be a condition of such
exchange that the Certificate so surrendered shall be properly endorsed and
otherwise in proper form for transfer and that the person requesting such
exchange shall pay to the Paying Agent any transfer or other Taxes (as defined
in Section 3.11(b) hereof) required by reason of the remittance of such Merger
Consideration to a person other than the registered holder of the Certificate so
surrendered, or shall establish to the satisfaction of the Paying Agent that
such Tax either has been paid or is not applicable. Parent or the Paying Agent
shall be entitled to deduct and withhold from the Merger Consideration otherwise
payable pursuant to this Agreement to any holder of shares of Common Stock such
amounts as Parent or the Paying Agent are required to deduct and withhold under
the Internal Revenue Code of 1986, as amended (the "Code"), or any provision of
state, local or foreign Tax law, with respect to the making of such payment. To
the extent that amounts are so withheld by Parent or the Paying Agent, such
withheld amounts shall be treated for all purposes of this Agreement as having
been paid to the holder of shares of Common Stock in respect of whom such
deduction and withholding was made by Parent or the Paying Agent.

     SECTION 1.5  Stock Options; Stock Units; Stock Purchase Plan.

     (a) As to options to purchase Common Stock outstanding under the Company's
Third Amended and Restated 1994 Stock Incentive Plan (the "1994 Company
Options"):

          (i) Not later than 30 days prior to the Effective Time, the Company
     shall send a notice (the "Option Notice") to all holders of 1994 Company
     Options stating: (A) that such options, by their terms, become exercisable
     in full as to the aggregate number of shares subject thereto at the
     Effective Time, (B) that the holder of any 1994 Company Options exercised
     prior to the Effective Time shall receive shares of Common Stock which will
     be converted into the right to receive $48 per share at the Effective Time,
     (C) that the holder of any 1994 Company Options exercised prior to but
     effective as of the Effective Time will receive $48 per share or, if
     exercised on a net basis pursuant to Section 1.5(a)(iii), the amount
     specified therein, and (D) that options outstanding after the Effective
     Time will be assumed by Parent and be exercisable to purchase shares of
     Parent common stock as provided in Section 1.5(a)(iv).

          (ii) The Company shall permit each holder of a 1994 Company Option who
     desires to exercise all or any portion of such 1994 Company Option
     following receipt of the Option Notice to exercise such 1994 Company Option
     prior to the Effective Time. To the extent 1994 Company Options would not
     be exercisable but for the Merger, such exercises may be made contingent on
     the Merger becoming effective.

          (iii) The Company shall offer to all holders of 1994 Company Options a
     procedure not provided in the agreements evidencing such options whereby
     the option holders may elect to exercise their options in advance of, but
     effective at, the Effective Time and not pay the exercise price in cash
     upon exercise but instead receive after the Effective Time the excess, if
     any, of (A) the product of the Merger Consideration multiplied by the
     aggregate number of shares of Common Stock subject to such 1994 Company
     Option immediately prior to the Effective Time over (B) the aggregate
     exercise price of all such shares of Common Stock subject to such 1994
     Company Option. The aggregate amount payable pursuant to this Section
     1.5(a)(iii) and Section 1.5(b)(ii) shall hereinafter be referred to as the
     "Option Cash-Out Amount." In no event shall the procedure described in this
     Section 1.5(a)(iii) be available with respect to 1994 Company Options
     assumed by Parent pursuant to Section 1.5(a)(iv).

          (iv) Each 1994 Company Option outstanding immediately after the
     Effective Time shall, without any action on the part of the holder thereof,
     be assumed by Parent in such manner that Parent (i) is a corporation
     "assuming a stock option in a transaction to which Section 424(a) applies"
     within the meaning of Section 424 of the Code and the regulations
     thereunder or (ii) to the extent that Section 424 of the Code does not
     apply to any such 1994 Company Option, would be such a corporation were
     Section 424 of the Code applicable to such 1994 Company Option. After the
     Effective Time, all references to the Company in the 1994 Company Options
     shall be deemed to refer to Parent. The 1994 Company Options assumed by
     Parent shall be exercisable upon the same terms and conditions except that
     (i) such 1994 Company Options shall entitle the holder to purchase from
     Parent the number of shares of Parent common stock (rounded down to the
     nearest whole number of such shares) that equals (X) the number of shares
     of Common Stock subject to such 1994 Company Option immediately prior to
     the Effective Time, multiplied by (Y) the quotient of $48 divided by the
     Formula Value of the Parent common stock, (ii) the option exercise price
     per share of Parent common stock shall be an amount (rounded up to the
     nearest full cent) equal to (X) the option exercise price per share of
     Common Stock in effect immediately prior to the Effective Time divided by
     (Y) the quotient of $48 divided by the Formula Value of the Parent common
     stock. The Formula Value of the Parent common stock will equal the average
     (rounded to the nearest full cent, with the cents rounded up if the third
     decimal place is 5 or more) of the closing sale prices (rounded to the
     nearest whole cent) of Parent common stock, on the New York Stock Exchange
     ("NYSE") Composite Tape as reported in The Wall Street Journal, for the ten
     (10) consecutive NYSE trading days ending on and including the NYSE trading
     day that is three NYSE trading days prior to the Effective Time.

     (b) As to options to purchase Common Stock issued under the MiniMed
Technologies Limited Amended and Restated 1992 Option Plan (the "1992 Plan") and
assumed by the Company (the "1992 Company Options"):

          (i) The committee of the Board of Directors administering the 1992
     Plan has accelerated the exercise dates of all outstanding 1992 Company
     Options contingent upon and effective as of the Effective Time so that all
     such options will be exercisable in full at that time.

          (ii) The Company shall offer to all holders of 1992 Company Options a
     procedure not provided in the agreements evidencing such options whereby
     the option holders may elect to exercise their options in advance of, but
     effective at, the Effective Time and not pay the exercise price in cash
     upon exercise but instead receive after the Effective Time the excess, if
     any, of (A) the product of the Merger Consideration multiplied by the
     aggregate number of shares of Common Stock subject to such 1992 Company
     Option immediately prior to the Effective Time over (B) the aggregate
     exercise price of all such shares of Common Stock subject to such 1992
     Company Option. The aggregate amount payable pursuant to this Section
     1.5(b)(ii) shall be included in the Option Cash-Out Amount as provided in
     Section 1.5(a)(iii) above. In no event shall the procedure described in
     this Section 1.5(b)(ii) be available with respect to 1992 Company Options
     assumed by Parent pursuant to Section 1.5(b)(iii).

          (iii) Each 1992 Company Option outstanding immediately after the
     Effective Time shall, without any action on the part of the holder thereof,
     be assumed by Parent in such manner that Parent (i) is a corporation
     "assuming a stock option in a transaction to which Section 424(a) applies"
     within the meaning of Section 424 of the Code and the regulations
     thereunder or (ii) to the extent that Section 424 of the Code does not
     apply to any such 1992 Company Option, would be such a corporation were
     Section 424 of the Code applicable to such 1992 Company Option. After the
     Effective Time, all references to the Company in the 1992 Company Options
     shall be deemed to refer to Parent. The 1992 Company Options assumed by
     Parent shall be exercisable upon the same terms and conditions except that
     (i) such 1992 Company Options shall entitle the holder to purchase from
     Parent the number of shares of Parent common stock (rounded down to the
     nearest whole number of such shares) that equals (X) the number of shares
     of Common Stock subject to such 1992 Company Option immediately prior to
     the Effective Time, multiplied by (Y) the quotient of $48 divided by the
     Formula Value of the Parent common stock and (ii) the option exercise price
     per share of Parent common stock shall be an amount (rounded up to the
     nearest full cent) equal to (X) the option exercise price per share of
     Common Stock in effect immediately prior to the Effective Time divided by
     (Y) the quotient of $48 divided by the Formula Value of the Parent common
     stock.

          (iv) The 1994 Company Options and the 1992 Company Options are
     referred to collectively in this Agreement as the "Company Options."

     (c) Non-Employee Director Deferred Stock Units Plan. Not later than 30 days
prior to the Effective Time, the Company shall send a notice to the holders of
outstanding units issued pursuant to the Non-Employee Director Deferred Stock
Units Plan (the "Units") stating: (i) that the Units shall not be assumed in
connection with the Merger, (ii) that rights under any Units outstanding as of
the Effective Time shall terminate and be cancelled at the Effective Time and
represent only the right to receive the consideration, if any, specified in this
Section 1.5(c) in accordance with this Agreement, and (iii) setting forth the
Merger Consideration. At the Effective Time, each Unit shall, by virtue of the
Merger and without any action on the part of the holder thereof, be converted
into, and represent only, the right to receive, upon delivery thereof to the
Company, an amount in cash equal to the Merger Consideration. The aggregate
amount payable pursuant to this paragraph (c) shall hereinafter be referred to
as the "Unit Cash-Out Amount."

     (d) Exchange Procedures for Company Options or Units. Promptly following
the Effective Time, Parent shall cause the Paying Agent to mail to each holder
of a Company Option exercised as of the Effective Time and to each holder of a
Unit outstanding at the Effective Time (i) a letter of transmittal (which shall
be in such form and have such other provisions as Parent may reasonably
specify), and (ii) instructions for use in receiving cash payable in respect of
such Company Options or Units. Upon the delivery of such letter of transmittal,
duly completed and validly executed in accordance with the instructions thereto,
together with the

                                       A-5
   6

documentation representing such Company Options or Units surrendered thereby, to
the Paying Agent, the holders of such Company Options shall be entitled to
receive the Option Cash-Out Amount or other amount payable to them in respect of
such Company Options pursuant to Section 1.5(a) or (b) or the Unit Cash-Out
Amount payable to them pursuant to Section 1.5(c).

     (e) ESPP. Not later than 30 days prior to the Effective Time, the Company
shall send notice to the holders of options under the Company's Employee Stock
Purchase Plan (the "ESPP") accelerating the exercise of such options for a 30
day period from the date of the notice. On the 30th day after the date of the
notice, in accordance with the terms of the ESPP, all rights to purchase shares
of Common Stock outstanding under the ESPP immediately prior to that date shall
be exercised (unless the participant withdraws as provided in the ESPP) and each
share of Common Stock purchased pursuant to such exercise shall, by virtue of
the Merger, and without any action on the part of the holder thereof, be
converted into the right to receive the Merger Consideration payable in respect
thereof. Any Common Stock issued pursuant to the ESPP shall be deemed issued and
outstanding at the Effective Time. The Company will offer to the participants in
the ESPP a procedure not provided for in the ESPP whereby no certificates
representing Common Stock of the Company will be issued upon exercise of the
options and after the Effective Time the holders will be entitled to receive
from the Paying Agent the Merger Consideration for each share of Common Stock
issued upon exercise of such options. Parent will make appropriate arrangements
with the Paying Agent so that participants in the ESPP who elect not to receive
stock certificates upon exercise of their options will be able to receive the
Merger Consideration to which they are entitled without the submission of stock
certificates. No offering or purchase periods under the ESPP shall be commenced
after the date hereof, no participant in the ESPP shall be permitted to increase
his or her level of participation in the ESPP after the date hereof, and the
ESPP and all purchase rights thereunder shall be terminated effective as of the
Effective Time.

     (f) Registration of Parent Common Stock. Parent will prepare and file with
the United States Securities and Exchange Commission (the "SEC") a registration
statement on Form S-8 (or any successor form) under the Securities Act of 1933,
as amended, and the rules and regulations thereunder (the "Securities Act"),
with respect to the shares of Parent common stock subject to the Company Options
assumed by Parent pursuant to Section 1.5(a) and (b), and, where applicable,
will use commercially reasonable efforts to have such registration statement
become effective at or prior to the Effective Time and to maintain the
effectiveness of such registration statement covering such Company Options (and
maintain the current status of the prospectus contained therein or required
pursuant thereto) for so long as any of such Company Options remain outstanding.

     SECTION 1.6  Lost Certificates. If any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Surviving Corporation, the posting by such person of a bond, in such
reasonable amount as the Surviving Corporation may direct, as indemnity against
any claim that may be made against it with respect to such Certificate, the
Paying Agent will pay the Merger Consideration to which the holder thereof is
entitled pursuant to this Article I in exchange for such lost, stolen or
destroyed Certificate.

     SECTION 1.7  Merger Closing. Subject to the satisfaction or waiver of the
conditions set forth in Article VI hereof, the closing of the Merger (the
"Closing") will take place at 10:00 a.m., California time, on the date that the
Company's stockholders vote to adopt this Agreement in accordance with the DGCL,
or as soon thereafter as, and in any event no later than the second business day
after, the conditions set forth in Article VI hereof have been satisfied or
waived, or on such other date and/or at such other time as Parent and the
Company may mutually agree. The date on which the Closing actually occurs is
referred to herein as the "Closing Date." The Closing shall take place by
telecopy exchange of signature pages with originals to follow by overnight
delivery, or in such other manner or at such place as the parties hereto may
agree. At the Closing, subject to the provisions of Article VI, Parent, Merger
Sub, and the Company shall cause the Certificate of Merger to be filed in
accordance with Section 1.1(b), and shall take any and all other lawful actions
and do any and all other lawful things necessary to cause the Merger to become
effective to the extent provided in Section 5.7.

     SECTION 2.1  Certificate Of Incorporation. The Certificate of Incorporation
of the Company, as in effect immediately prior to the Effective Time, shall be
amended as of the Effective Time to read as set forth on Exhibit A to this
Agreement.

     SECTION 2.2  Bylaws. The Bylaws of Merger Sub, as in effect immediately

     SECTION 2.3  Directors. The directors of Merger Sub immediately prior to

                                  ARTICLE III

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     Except (i) as set forth in a document (the "Company Disclosure Schedule")
of even date herewith and concurrently delivered herewith, referring
specifically to the representations and warranties in this Agreement and which
identifies by section number the section of this Article III to which such
disclosure relates unless the relevance and magnitude of such disclosure to
another section of this Agreement is reasonably evident, without the need for
additional information or explanation, from the contents of the referenced
disclosure or the nature of the document in question, or (ii) as specifically
described through express disclosure of current, specific facts (excluding
statements of possibilities, potential risks or general qualifications) set
forth in the Company's Annual Report on Form 10-K for the fiscal year ended
December 29, 2000, in the Company's Quarterly Report on Form 10-Q for the
quarter ended March 30, 2001, or in the Company's 2001 Proxy Statement, to the
extent the relevancy of such disclosure to such particular representation and
warranty is readily apparent, the Company hereby makes the following
representations and warranties to Parent and Merger Sub:

     SECTION 3.1  Corporate Existence And Power. The Company is a corporation
duly incorporated, validly existing and in good standing under the laws of the
State of Delaware, and has all corporate powers and all governmental licenses,
authorizations, consents and approvals (collectively, "Licenses") required to
carry on its business as now conducted except for failures to have any such
License which could not reasonably be expected to have, individually or in the
aggregate, a Company Material Adverse Effect (as defined below). The Company is
duly qualified to do business as a foreign corporation and is in good standing
in each jurisdiction where the character of the property owned, leased or
operated by it or the nature of its activities makes such qualification
necessary, except in such jurisdictions where failures to be so qualified could
not reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect. As used herein, the term "Company Material Adverse

contemplated hereby and as of the Effective Time, contain any untrue statement
of a material fact or omit to state any material fact required to be stated
therein or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading. The Proxy Statement

would be deemed a "single employer" within the meaning of Section 4001(b) of
ERISA, or to which the Company, any Subsidiary of the Company, or an ERISA

in the aggregate, a Company Material Adverse Effect by or on behalf of any Plan,
or by any employee or beneficiary covered under any such Plan (other than
routine claims for benefits). No event has occurred and, to the knowledge of the
Company, there exists no condition or set of circumstances in connection with
which the Company or any of its Subsidiaries would be subject to any liability

individually or in the aggregate, a Company Material Adverse Effect.

     (i) The consummation of the transactions contemplated by this Agreement
will not, either alone or in combination with another event, (i) entitle any
current or former employee or officer of the Company or any ERISA Affiliate to
severance pay, unemployment compensation or any other payment, except as
expressly provided in this Agreement, or (ii) accelerate the time of payment or
vesting, or increase the amount of compensation due any such employee or
officer, other than payments, accelerations or increases (x) under any employee

subject to the laws of any jurisdiction outside the United States are in
material compliance with such applicable laws, including relevant Tax laws, and
the requirements of any trust deed under which they were established, except for
such exceptions to the foregoing which, in the aggregate, could not reasonably
be expected to have, individually or in the aggregate, a Company Material
Adverse Effect. Schedule 3.12(k) lists all material employee pension benefit
plans that are subject to the laws of any jurisdiction outside the United
States.

     (l) Each Plan can be amended prospectively or terminated at any time,
without advance notice, and without any liability other than for benefits
accrued prior to such amendment or termination (other than administrative
charges normally incurred in a plan termination).

     (m) No agreement, commitment, or obligation exists to increase any benefits
under any Plan or to adopt any new Plan.

     (n) No Plan has any unfunded accrued benefits that are not fully reflected
in the Company Audited Balance Sheet.

     (o) No pension plan subject to Title IV of ERISA (an "ERISA Pension Plan")
has incurred any "accumulated funding deficiency" or "waived funding deficiency"
within the meaning of Section 302 of ERISA or Section 412 of the Code and
neither the Company nor any Subsidiary of the Company has ever sought to obtain
any variance from the minimum funding standards pursuant to Section 412(d) of
the Code. The funding method used in connection with each ERISA Pension Plan
meets the requirements of ERISA and the Code and the actuarial assumptions used
in connection with each such plan are reasonable, given the experience of such
ERISA Pension Plan and reasonable expectations.

     (p) The fair market value of the plan assets of each ERISA Pension Plan are
at least equal to (i) the present value of its benefit liabilities (as defined
in ERISA Section 4001(a)(16)), including any unpredictable contingent event
benefits within the meaning of Code Section 412(l)(7), and determined on the
basis of assumptions prescribed by the PBGC for purposes of ERISA Section 4044),
and (ii) the Projected Benefit Obligations thereunder, as defined in Statement
of Financial Accounting Standards No. 87, including any allowance for indexation
and ad hoc increases. No ERISA Pension Plan has been completely or partially
terminated or been the subject of a Reportable Event under ERISA Section 4043.
No proceeding by the PBGC to terminate any ERISA Pension Plan has been
instituted, and neither the Company nor any Subsidiary of the Company has
incurred any liability to the PBGC (other than the PBGC premiums, all of which
have been timely paid) or otherwise under Title IV of ERISA with respect to any
ERISA Pension Plan.

     (q) Neither the Company nor any Subsidiary of the Company maintains or
participates in any Voluntary Employees' Beneficiary Association, under Code
Sections 419 and 419A, which is intended to be exempt from taxation under
section 501(c)(9) of the Code.

in their capacity as officers or directors of the Company or of any Subsidiary
of the Company which could reasonably be expected to have, individually or in
the aggregate, a Company Material Adverse Effect.

     (b) Neither the Company nor any Subsidiary of the Company is in default or
violation of any applicable federal, state, local, or foreign laws, ordinances,
regulations, interpretations, judgments, decrees, injunctions, permits,
licenses, certificates, governmental requirements, orders, or other
promulgations, of any court or other Governmental Entity (and including those of
any nongovernmental self-regulatory agency and including environmental laws or

be expected to have, individually or in the aggregate, a Company Material
Adverse Effect. The Company and each Subsidiary of the Company has timely filed
or otherwise provided all registrations, reports, data, and other information

of the Regulated Products, has complied with all applicable requirements of the
FDA or other Governmental Entity with respect to the Regulated Products, and all
regulatory licenses or approvals in respect thereof are in full force and
effect, except where the failure to file timely such registrations, reports,
data, information, and applications or to be in compliance or the failure to
have such licenses and approvals in full force and effect could not reasonably
be expected to have, individually or in the aggregate, a Company Material
Adverse Effect. All documentation, correspondence, reports, data, analyses and
certifications relating to or regarding any medical devices of the Company or
any Subsidiary of the Company, filed with or delivered by or on behalf of the
Company or any Subsidiary of the Company to any Governmental Entity was in all
material respects true and accurate when so filed or delivered and, to the
knowledge of the Company, remains true and accurate. All governmental approvals,
permits and licenses (collectively, "Permits") required to conduct the business
of the Company and its Subsidiaries as it is currently being conducted have been
obtained, are in full force and effect and are being complied with, except where
such failure could not reasonably be expected to have a Company Material Adverse

Opportunity Commission or any other agency responsible for the prevention of
unlawful employment practices; and (vi) there are no collective bargaining
agreements with any union covering employees of the Company or any Subsidiary of
the Company, except for such exceptions to the foregoing clauses (i) through
(vi) which could not reasonably be expected to have, individually or in the
aggregate, a Company Material Adverse Effect.

     SECTION 3.15  Certain Contracts And Arrangements. Schedule 3.15 of the
Company Disclosure Schedule lists, and the Company has heretofore furnished to
Parent complete and accurate copies of (or, if oral, the Company Disclosure
Schedule states all material provisions of), (a) every employment, material
consulting, severance or change of control agreement or arrangement for the
benefit of any director, officer, employee, other person or stockholder of the
Company or any Subsidiary of the Company or any affiliate thereof in effect as

Company is a party or by which the Company or any Subsidiary of the Company or
any of their properties or assets is bound, (b) every material contract with
physicians, scientific advisory board members or material consultants in

Company or any of their properties or assets is bound, and (c) every contract,

reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect, or that is material and was not made in the ordinary
course of business. Each material contract or agreement to which the Company or
any Subsidiary of the Company is a party or by which any of them is bound is in
full force and effect, and neither the Company nor any Subsidiary of the
Company, nor, to the knowledge of the Company, any other party thereto, is in
breach of, or default under, any material contract or material agreement to
which the Company or any Subsidiary of the Company is a party or by which any of
them is bound, and no event has occurred that with notice or passage of time or
both would constitute such a breach or default thereunder by the Company or any
Subsidiary of the Company, or, to the knowledge of the Company, any other party
thereto, except for such breaches and defaults which could not reasonably be
expected to have, individually or in the aggregate, a Company Material Adverse

of the Company is a party to any contract, plan, agreement, understanding,
arrangement or obligation (i) that restricts the ability of the Company or any

rights to any person under the Rights Plan or enable the rights to purchase the
Company's Series B Junior Participating Cumulative Preferred Stock to be
exercised, or require that they be separated, distributed or triggered, and so
that as of the Effective Time such rights shall, without any payment by the

            REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB

     Parent and Merger Sub, jointly and severally, represent and warrant to the
Company as follows:

     SECTION 4.1  Corporate Existence and Authorization. Each of Parent and
Merger Sub is a corporation duly incorporated, validly existing and in good

and delivery by Parent and Merger Sub of this Agreement and the performance of
their obligations hereunder have been duly and validly authorized by the Boards
of Directors of Parent and Merger Sub and by Parent as the sole stockholder of
Merger Sub, and no other action of Parent's or Merger Sub's Board of Directors
or corporate proceedings on the part of Parent or Merger Sub are necessary to
authorize the execution, delivery and performance of this Agreement or to
consummate the transactions contemplated hereby. This Agreement has been duly
executed and delivered by each of Parent and Merger Sub and constitutes,
assuming due authorization, execution and delivery of this Agreement by the
Company, a valid and binding obligation of each of Parent and Merger Sub,
enforceable against each of them in accordance with its terms, subject to laws
of general application relating to bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium and other similar laws affecting
creditors rights generally, and general equitable principles (whether considered

respect to the Merger with the Secretary of State; (b) compliance with any
applicable requirements of the HSR Act and Foreign Merger Laws; (c) compliance
with any applicable requirements of the federal securities laws and state blue
sky or takeover laws; and (d) such other consents, approvals, orders,
authorizations, notifications, registrations, declarations and filings the
failure of which to be obtained or made could not reasonably be expected to be,
individually or in the aggregate, materially adverse to Parent's or Merger Sub's
ability to perform any of their material obligations under this Agreement or to
consummate the Merger.

     SECTION 4.3  Non-Contravention. The execution, delivery and performance by
Parent and Merger Sub of this Agreement and the consummation by Parent and
Merger Sub of the transactions contemplated hereby do not and will not: (a)
conflict with or result in a breach of any provision of the current articles or
certificate of incorporation or bylaws of Parent or Merger Sub; (b) assuming the
filings, registrations, notifications, authorizations, consents and approvals
referred to in Section 4.2 have been obtained or made, violate any order,
injunction, decree, statute, rule or regulation of any Governmental Entity to

rise to any right of termination, cancellation or acceleration of any right or
obligation of Parent or Merger Sub or to a loss of any benefit to which Parent
or Merger Sub is entitled under any provision of any agreement, contract or
other instrument binding upon Parent or Merger Sub, in any manner that would
reasonably be expected to prevent, hinder or delay the timely completion of the
transactions contemplated by this Agreement.

     SECTION 4.4  Litigation. There is no action pending or, to the knowledge of
Parent, threatened, against or affecting Parent or any of its Subsidiaries or
any of their respective properties or any of their respective officers or

would, individually or in the aggregate, reasonably be expected to prevent,
hinder or delay the timely completion of the transactions contemplated by this
Agreement.

Certificate of Incorporation and the Bylaws of the Company duly call, give
notice of, convene and hold the Company Stockholders' Meeting as promptly as
practicable after the date hereof for the purpose of considering and taking
action upon the adoption of this Agreement (the "Company Approval Matters").
Except as provided in Section 5.5, the Company shall use reasonable best efforts
to solicit from its stockholders proxies in favor of the adoption of this
Agreement pursuant to the Proxy Statement and shall take all other action
reasonably necessary or advisable to secure the vote or consent of stockholders
required by the DGCL or applicable stock exchange requirements to obtain such

Company's Certificate of Incorporation and Bylaws to effect the Merger.

     (b) Promptly following the date of this Agreement, the Company shall
prepare and file with the SEC a proxy statement relating to the Company Approval
Matters (together with any amendments thereof and any supplements thereto, the
"Proxy Statement"). Parent and the Company shall cooperate with each other in
connection with the preparation of the Proxy Statement. The Company will use
reasonable best efforts to cause the Proxy Statement to be mailed to the
Company's stockholders as promptly as practicable after the date hereof. The
Proxy Statement shall include (i) the recommendation of the Board of Directors

     (c) The Company shall as promptly as practicable notify (and provide copies

     (d) Unless and until this Agreement is validly terminated pursuant to
Article VII, nothing herein shall limit or eliminate in any way the Company's
obligation to call, give notice of, convene and hold the Company Stockholders'
Meeting and at such meeting submit this Agreement and the Merger to a vote of
the Company's stockholders (and not postpone or adjourn such meeting or the vote
by the Company's stockholders upon this Agreement and the Merger to another date
without Parent's approval).

     SECTION 5.4  Access To Information; Confidentiality Agreement

     (a) Except as required pursuant to any confidentiality agreement or similar
agreement or arrangement to which the Company or any of the Company's
Subsidiaries is a party (in which case the Company shall use all commercially
reasonable efforts to provide acceptable alternative arrangements, not in
violation of such agreement or arrangement, for disclosure to Parent or its
advisors) or pursuant to applicable law or the regulations or requirements of
any stock exchange or other regulatory organization with whose rules the Company
is required to comply, from the date of this Agreement to the Effective Time,
the Company shall (and shall direct its Subsidiaries to) (i) provide to Parent
(and its officers, directors, employees, accountants, consultants, legal
counsel, agents and other representatives (collectively, "Representatives"))
access at reasonable times during normal business hours in a manner so as not to
unreasonably disrupt the ordinary course of business upon prior written notice
to its and its Subsidiaries' officers, employees, agents, properties, offices
and other facilities and to the books and records thereof, and (ii) furnish
promptly to Parent all information concerning the Company's and its
Subsidiaries' businesses, prospects, properties, liabilities, results of
operations, financial condition, product evaluations and testing, pilot studies,
clinical data and studies and evaluations, patient results, regulatory
compliance, officers, employees, third party physicians and clinical
investigators, consultants, distributors, customers, suppliers, and others
having material dealings with the Company as Parent may reasonably request and
reasonable opportunity to contact and obtain information

                                       A-23
   24

from such officers, employees, investigators, consultants, distributors,
customers, suppliers, and others having dealings with the Company as Parent may
reasonably request. Subject to the foregoing provisions, the Company's
obligation to afford access and provide information pursuant to the preceding
sentence shall include such access and information as Parent shall reasonably
deem necessary to enable Parent, or a third party designated by Parent and
approved by the Company, to conduct a reasonable audit of the Company's and its
Subsidiaries' product performance and quality, pilot studies, clinical data and
results, patient results, compliance with FDA regulations, policies and
procedures, relations and dealings with third party physicians and other
clinical investigators and consultants, and related performance and compliance
matters concerning the Company's and its Subsidiaries' products. During the
period from the date hereof to the Effective Time, the parties shall in good
faith meet and correspond on a regular basis for mutual consultation concerning
the conduct of the Company's and its Subsidiaries' businesses and, in connection
therewith, Parent shall be entitled to be kept informed concerning, the
Company's and its Subsidiaries' operations and business planning. No
investigation conducted pursuant to this Section 5.4 shall affect or be deemed
to modify any representation or warranty made in this Agreement or modify or
expand the conditions to closing set forth in Article VI. Nothing in this
Agreement will require disclosure prior to the Effective Time of minutes,
reports, or documents related to the Special Committee.

     (b) Parent and each of its employees and other representatives shall hold
in confidence all such nonpublic information as required and in accordance with
the confidentiality agreement between Parent and the Company dated April 26,
2000 (the "Confidentiality Agreement").

     SECTION 5.5  No Solicitation.

     (a) The Company shall not (whether directly or indirectly through advisors,
agents or other intermediaries), and the Company shall cause its respective
officers, directors, advisors, representatives or other agents (including any
investment banker, attorney, or accountant retained by the Company or any
Subsidiary) not to, directly or indirectly, (1) solicit, initiate or knowingly
encourage any Acquisition Proposal (as defined hereafter) or (2) participate in
or encourage in any way discussions or negotiations with, or provide any
nonpublic information to, any corporation, partnership, person, or other entity
or group (other than Parent or any affiliate or agent of Parent) concerning any
Acquisition Proposal, or otherwise facilitate any effort or attempt to make or
implement an Acquisition Proposal; provided, however, that, notwithstanding the
foregoing provisions of this Section 5.5, this Agreement shall not prohibit the
Company's Special Committee from, prior to the date on which the Company's
stockholders adopt this Agreement in accordance with the DGCL, furnishing
nonpublic information to or entering into discussions or negotiations with, any
person or entity that makes an unsolicited Superior Proposal, if, and only to
the extent that, (i) the failure of the Company's Board of Directors to take
action with respect to a Superior Proposal would be a breach of the Board's
fiduciary duties to its shareholders imposed by applicable law; (ii) prior to
first furnishing nonpublic information to, or first entering into substantive
discussions and negotiations with, such person or entity after the date hereof,
the Company (A) provides written notice of at least five business days to Parent
to the effect that it intends to furnish information to, or enter into
discussions or negotiations with, such person or entity, and naming and
identifying the person or entity making the Acquisition Proposal, and (B)
receives from such person or entity an executed confidentiality agreement with
terms no less favorable to the Company than the Confidentiality Agreement (as
defined in Section 5.4(b)) entered into with Parent; and (iii) the Company
concurrently provides Parent with all non-public information to be provided to
such person or entity that Parent has not previously received from the Company,
and the Company keeps Parent informed, on a daily or more regular basis if the
context requires or Parent so requests, of the status, terms and conditions and
all other material information with respect to any such discussions or
negotiations.

     (b) For purposes of this Agreement, "Acquisition Proposal" means any offer
or proposal for any of the following involving the Company or any Subsidiary of
the Company: (i) any tender offer, exchange offer, merger, consolidation, share
exchange, business combination or similar transaction involving more than fifty
percent of capital stock of the Company or any Subsidiary of the Company; (ii)
any transaction or series of related transactions pursuant to which any person
or entity (or its stockholders), other than Parent, or Merger Sub or any of
their affiliates (a "Third Party") acquires shares (or securities exercisable
for or convertible into shares) representing more than fifty percent of the
outstanding shares of any class of capital stock of the

                                       A-24
   25

Company or any Subsidiary of the Company; or (iii) any sale, lease, exchange,
licensing, transfer or other disposition pursuant to which a Third Party
acquires control of more than 20% of the assets (including, but not limited to,
intellectual property assets) of the Company and its Subsidiaries taken as a
whole (determined by reference to the fair market value of such assets), in a
single transaction or series of related transactions.

     (c) As used herein, a "Superior Proposal" shall mean a bona fide
Acquisition Proposal (i) that the Company's Special Committee has reasonably and
in good faith determined (with the advice of its financial advisors and taking
into account all material legal, financial and regulatory aspects of such
Acquisition Proposal) to be more favorable to the Company's stockholders than
the transactions contemplated by this Agreement; and (ii) with respect to which
the financing required to consummate the transaction contemplated by such
Acquisition Proposal is committed or in the good faith determination of the
Company's Special Committee, after consultation with its financial advisor, is
likely to be obtained on a timely basis.

     (d) The Company will immediately terminate all discussions with Third
Parties concerning any Acquisition Proposal, and will request that such Third
Parties promptly return any confidential information furnished by the Company in
connection with any Acquisition Proposal. Subject to this Section 5.5, the
Company will not waive any provision of any confidentiality, standstill or
similar agreement entered into with any Third Party regarding any Acquisition
Proposal, and prior to the Closing shall enforce all such agreements in
accordance with their terms. The Company will promptly communicate to Parent the
name of the person or entity submitting, and a detailed description of the terms
and conditions of, any proposal or inquiry that it receives after the date
hereof in respect of any Acquisition Proposal or a reasonably detailed
description of any such information requested from it after the date hereof or
of any such negotiations or discussions being sought to be initiated or
continued with the Company after the date hereof in respect of an Acquisition
Proposal.

     (e) Nothing contained in this Section 5.5 shall (i) permit the Company to
terminate this Agreement (except as specifically provided in Article VII
hereof), or (ii) permit the Company to enter into any agreement providing for an
Acquisition Proposal (other than the confidentiality agreement as provided, and
in the circumstances and under the conditions set forth, above) for as long as
this Agreement remains in effect.

     (f) Nothing contained in this Section 5.5 shall prohibit the Company or the
Company's Board of Directors from taking and disclosing to the Company's
stockholders a position with respect to a tender or exchange offer by a third
party pursuant to Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act or
from making any disclosure required by applicable law.

     SECTION 5.6  Director And Officer Liability.

     (a) Parent and the Company agree that all rights to indemnification and
advancement of expenses and all limitations on liability existing in favor of
any Indemnitee (as defined hereafter) as provided in the Certificate of
Incorporation or Bylaws of the Company existing on the date of this Agreement
shall survive the Merger and continue in full force and effect in accordance
with its terms for at least six years after the Effective Time, unless
modification of such rights or limitations is required by law.

     (b) For six years after the Effective Time, Parent shall or shall cause the
Surviving Corporation to indemnify and hold harmless, and to advance expenses
to, the individuals who on or prior to the Effective Time were officers,
directors, employees or agents of the Company (the "Indemnitees") to the full
extent permitted by applicable law. In the event any claim in respect of which
indemnification is available pursuant to the foregoing provisions is or may be
asserted or made within such six-year period, all rights to indemnification and
advancement of expenses shall continue until such claim is disposed of or all
judgments, orders, decrees or other rulings in connection with such claim are
fully satisfied.

     (c) From and after the Effective Time, Parent will cause the Surviving
Corporation to fulfill and honor in all respects the obligations of the Company
pursuant to each indemnification agreement that is described in Schedule 5.6 of
the Company Disclosure Schedule and is in effect at the Effective Time. Parent
shall guarantee the obligations of the Surviving Corporation with respect to the
indemnification and payment of fees and expenses provisions contained in the
Surviving Corporation's Certificate of Incorporation and Bylaws with

                                       A-25
   26

respect to acts occurring at or before the Effective Time (including the
transactions contemplated by this Agreement).

     (d) For a period of three years after the Effective Time, Parent shall, at
its selection, either: (i) cause to be maintained in effect the Company's
current directors' and officers' liability insurance policy (a copy of which has
been heretofore delivered or made available to Parent or its advisors) with
respect to claims arising from facts or events that occurred at or prior to the
Effective Time; or (ii) extend the discovery or reporting period under the
Company's current policy for three years from the Effective Time to maintain in
effect directors' and officers' liability insurance with respect to claims
arising from facts or events that occurred at or prior to the Effective Time for
those persons who are currently covered by the Company's directors' and
officers' liability insurance policy on terms no less favorable than the terms
of such current insurance policy; or (iii) substitute coverage under Parent's
directors' and officers' liability insurance or coverage under other policies
providing coverage on terms and conditions that are no less advantageous to such
persons than the Company's current insurance with respect to claims arising from
facts or events that occurred at or prior to the Effective Time; provided,
however, that in no event shall Parent be required to expend for any such
coverage an amount per year in excess of 150% of the annual premium currently
paid by the Company for such insurance; and provided further that if the cost
per year of such coverage exceeds such 150% amount, Parent shall be obligated to
obtain such coverage as is available for a cost per year not exceeding such
amount. The Company represents that the Company Disclosure Schedule sets forth
the annual premium currently paid by the Company for such insurance.

     (e) In the event Parent, the Surviving Corporation or any of their
successors or assigns (i) consolidates with or merges into any other person and
shall not be the continuing or surviving corporation or entity of such
consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any person, then and in each such case, proper
provisions shall be made so that the successors and assigns of Parent or the
Surviving Corporation, as the case may be, shall assume the obligations set
forth in this Section 5.6.

     (f) This Section 5.6 shall survive the consummation of the Merger at the
Effective Time, is intended to benefit the Company, Parent, the Surviving
Corporation and the Indemnitees, and shall be binding on all successors and
assigns of Parent and the Surviving Corporation.

     SECTION 5.7  Commercially Reasonable Efforts. Upon the terms and subject to
the conditions of this Agreement, each party hereto shall use commercially
reasonable efforts to take, or cause to be taken, all actions and to do, or
cause to be done, all things necessary, proper or advisable under applicable
laws and regulations to consummate the transactions contemplated by this
Agreement.

     SECTION 5.8  Consents; Certain Filings.

     (a) The Company and Parent shall cooperate with one another (i) in
connection with the preparation of the Proxy Statement, (ii) in determining
whether any action by or in respect of, or filing with, any Governmental Entity
is required, or any actions, consents, approvals or waivers are required to be
obtained from parties to any material contracts, in connection with the
consummation of the transactions contemplated by this Agreement and (iii) in
seeking any such actions, consents, approvals or waivers or making any such
filings, furnishing information required in connection therewith or with the
Proxy Statement and seeking timely to obtain any such actions, consents,
approvals or waivers.

     (b) Without limiting the provisions of this Section 5.8, each party hereto
shall, if applicable, file with the Department of Justice and the Federal Trade
Commission a Pre-Merger Notification and Report Form pursuant to the HSR Act in
respect of the transactions contemplated hereby as soon as reasonably
practicable, and each party will use commercially reasonable efforts to take or
cause to be taken all actions necessary, including to promptly and fully comply
with any requests for information from regulatory Governmental Entities, to
obtain any clearance, waiver, approval or authorization relating to the HSR Act
that is necessary to enable the parties to consummate the transactions
contemplated by this Agreement. Without limiting the provisions of this Section
5.8, each party hereto shall use commercially reasonable efforts to promptly
make the filings required to be made by it with all foreign Governmental
Entities in any jurisdiction in which the parties believe it is necessary or
advisable.

                                       A-26
   27

     (c) The Company and Parent shall each use commercially reasonable efforts
to resolve such objections, if any, as may be asserted with respect to the
Merger or any other transaction contemplated by this Agreement under any
Antitrust Law (as defined below). If any administrative, judicial or legislative
action or proceeding is instituted (or threatened to be instituted) challenging
the Merger or any other transaction contemplated by this Agreement as violative
of any Antitrust Law, the Company and Parent shall each cooperate to contest and
resist any such action or proceeding, and to have vacated, lifted, reversed or
overturned any decree, judgment, injunction or other order (whether temporary,
preliminary or permanent) that is in effect and that restricts, prevents or
prohibits consummation of the Merger or any other transaction contemplated by
this Agreement, including, without limitation, by pursuing all reasonable
avenues of administrative and judicial appeal. Notwithstanding anything to the
contrary in this Agreement, none of Parent, any of its Subsidiaries or the
Surviving Corporation, shall be required (and the Company shall not, without the
prior written consent of Parent, agree, but shall, if so directed by Parent,
agree, effective after the Effective Time) to hold separate or divest any of
their respective assets or operations or enter into any consent decree or
licensing or other arrangement with respect to any of their assets or operations
or to otherwise take or commit to take any action that limits its freedom of
action with respect to, or its ability to retain, as of and after the Effective
Time any businesses or assets of the Company, Parent or any of their respective
affiliates.

     (d) Each of the Company and Parent shall promptly inform the other party of
any material communication received by such party from the Federal Trade
Commission, the Antitrust Division of the Department of Justice or any other
governmental or regulatory authority regarding any of the transactions
contemplated hereby.

     (e) The Company will, at its cost and expense, use all reasonable efforts
to obtain all approvals and consents of all third parties necessary on the part
of the Company or its Subsidiaries to promptly consummate the transactions
contemplated hereby. Parent agrees to cooperate with the Company in connection
with obtaining such approvals and consents. Parent will, at its cost and
expense, use all reasonable efforts to obtain all approvals and consents of all
third parties necessary on the part of Parent or Merger Sub to promptly
consummate the transactions contemplated hereby. The Company agrees to cooperate
with Parent in connection with obtaining such approvals and consents.

     (f) "Antitrust Law" means the Sherman Act, as amended, the Clayton Act, as
amended, and all other federal, state and foreign statutes, rules, regulations,
orders, decrees, administrative and judicial doctrines, and other laws that are
designed or intended to prohibit, restrict or regulate competition or actions
having the purpose or effect of monopolization or restraint of trade.

     SECTION 5.9  Public Announcements. The parties shall issue press releases
in agreed upon form announcing the execution of this Agreement as soon as
practicable on or after the date hereof. Neither the Company, Parent nor any of
their respective affiliates shall issue or cause the publication of any press
release or other public announcement with respect to the Merger, this Agreement
or the other transactions contemplated hereby without the prior written consent
of the other party, except as may be required by law or by any listing agreement
with, or the policies of, a national securities exchange or the NASDAQ National
Market.

     SECTION 5.10  Further Assurances. At and after the Effective Time, the
officers and directors of the Surviving Corporation will be authorized to
execute and deliver, in the name and on behalf of the Company or Merger Sub, any
deeds, bills of sale, assignments or assurances and to take and do, in the name
and on behalf of the Company or Merger Sub, any other actions to vest, perfect
or confirm of record or otherwise in the Surviving Corporation any and all
right, title and interest in, to and under any of the rights, properties or
assets of the Company acquired or to be acquired by the Surviving Corporation,
as a result of, or in connection with, the Merger.

     SECTION 5.11  Employee Matters.

     (a) From and after the Effective Time, Parent shall to the extent
practicable cause the Surviving Corporation to provide employee benefits and
programs to the Company's employees that, in the aggregate, are substantially
comparable or more favorable, as a whole, than those in existence as of the date
hereof and

                                       A-27
   28

disclosed in writing to Parent prior to the execution hereof; provided that
stock-based compensation shall be comparable to that offered by Parent and its
subsidiaries generally. To the extent Parent satisfies its obligations under
this Section by maintaining Company benefit plans, Parent shall not be required
to include employees of the Company in Parent's benefit plans.

     (b) Parent shall, or shall cause the Company to, give individuals who are
employed by the Company or any of its Subsidiaries as of the Effective Time and
who remain employees of the Company or such Subsidiary following the Effective
Time (each such employee, an "Affected Employee") full credit to the extent each
such Affected Employee has been credited with service under each comparable
employee benefit plan or arrangement maintained by the Company immediately prior
to the Effective Time for purposes of eligibility, level of participation and
vesting under each employee benefit plan or arrangement maintained by Parent or
the Company for such Affected Employee's service with the Company.

     (c) Under no circumstances shall employees receive credit for service
accrued or deemed accrued prior to the Effective Time with the Company or such
Subsidiary, as the case may be, for benefit accruals under any employee pension
benefit plan (as defined by Section 3(2) of ERISA) or any retiree health plan.

     SECTION 5.12  State Takeover Laws. If any "fair price," "business
combination" or "control share acquisition" statute or other similar statute or
regulation is or may become applicable to the Merger, the Company shall take
such actions as are necessary so that the transactions contemplated by this
Agreement may be consummated as promptly as practicable on the terms
contemplated hereby and otherwise act to eliminate or minimize the effects of
any such statute or regulation on the Merger.

     SECTION 5.13  Certain Notifications. Between the date hereof and the
Effective Time, the Company and Parent shall each promptly notify the other in
writing after becoming aware of the occurrence of any event which will, or is
reasonably likely to, result in the failure to satisfy any of the conditions to
such other party's obligations specified in Article VI.

     SECTION 5.14  Voting of Shares. To induce Parent to execute this Agreement,
certain officers and directors of the Company have executed and delivered as of
the date hereof Agreements to Facilitate Merger in the form attached hereto as
Exhibit B, pursuant to which each such person has agreed to vote all of his or
her shares of Common Stock in favor of the adoption of this Agreement. To the

no or nominal consideration to such person or persons designated by Parent.

     (a) Parent will not consummate the transactions contemplated under the
Agreement and Plan of Merger dated of even date herewith (the "MRG Agreement")
between Parent and Medical Research Group, Inc. ("MRG") prior to the Effective

                                       A-28
   29

could (with the passage of time or occurrence of events) result in the
Termination Fee being paid or payable pursuant to Section 7.3.

     (b) Parent will not amend or modify the MRG Agreement or waive any rights
thereunder in a manner that would reasonably be expected to prevent or delay the
Effective Time or the timely closing under the MRG Agreement.

     the consummation of the Merger, or (ii) would impose any material
     limitation on the ability of Parent to effectively exercise full rights of
     ownership of the Company or the assets or business of the Company or its
     Subsidiaries;

     SECTION 6.2  Conditions To The Company's Obligation To Consummate The

          (b) The representations and warranties of the Company contained in
     this Agreement, without regard to any qualification or reference to
     "material," "in all material respects," "Company Material Adverse Effect,"

     except in any case for any inaccuracies of representations and warranties
     that have not had, or could

                                       A-29
   30

     not reasonably be expected to have, individually or in the aggregate, a
     Company Material Adverse Effect; provided, however, notwithstanding the

     satisfied if the representation and warranty set forth in the last sentence
     of Section 3.4 is incorrect as of the Closing Date;

          (c) Parent shall have received a certificate signed by the chief
     executive officer of the Company, dated the Closing Date, to the effect
     that the conditions set forth in Sections 6.3(a) and 6.3(b) hereof have

          (d) The Company shall have obtained all permits, authorizations,
     consents, and approvals required on its part to perform its obligations
     under, and consummate the transactions contemplated by, this Agreement, in
     form and substance satisfactory to Parent, except for such permits,
     authorizations, consents and approvals the failure of which to obtain could
     not reasonably be expected to have, individually or in the aggregate, a
     Company Material Adverse Effect, and Parent and Merger Sub shall have
     received evidence satisfactory to them of the receipt of such permits,
     authorizations, consents, and approvals;

          (e) Since the date of this Agreement, there shall not have occurred or

     development that has had, or could reasonably be expected to have,
     individually or in the aggregate, a Company Material Adverse Effect;

          (f) Parent shall have received executed agreements from such persons,
     and in such form satisfactory to Parent, with respect to the transfer of

     the Merger have been satisfied or waived there shall not exist (A) any
     failure of the representations and warranties of MRG contained in the MRG
     Agreement (without regard to any qualification or reference to "material,"
     "in all material respects," "Material Adverse Effect," or similar
     variations thereof) to be true and correct or (B) any change, event,
     occurrence, state of facts or development with respect to MRG that, in the
     case of each of clause (A) or (B), has had or could reasonably be expected
     to have, individually or in the aggregate, a Company Material Adverse
     Effect. Solely for purposes of applying the definition of Company Material
     Adverse Effect to this Section 6.3(g), "Company" means the Company and MRG
     taken together as a whole).

          (ii) Upon learning of any fact or circumstance that Parent determines
     would lead to the closing condition set forth in this Section 6.3(g) not
     being met (a "Potential Closing Problem"), Parent will give to the Company
     prompt notice thereof and keep the Company reasonably informed (on a daily
     or more frequent basis if the context requires or the Company so requests)
     of the status, facts, and other material information with respect to any
     such matter; provided that failure to give such notice shall not adversely
     affect Parent's rights except, and only to the extent that, the Company
     demonstrates it has been prejudiced by such failure. Parent will, at the
     Company's request allow the Company and its representatives to be directly
     involved in the discussions or negotiations with respect to any Potential
     Closing Problem, and afford the Company and its representatives a
     reasonable opportunity to actively participate in attempting to resolve the
     Potential Closing Problem in a manner reasonably satisfactory to Parent.

          (h) All applicable waiting periods under the HSR Act or any Foreign
     Merger Law relating to the transactions contemplated by the MRG Agreement
     shall have expired or been terminated.

                                  TERMINATION

     SECTION 7.1  Termination. Notwithstanding anything herein to the contrary,
this Agreement may be terminated and the transactions contemplated by this
Agreement may be abandoned at any time prior to the Closing Date, whether before
or after this Agreement has been adopted by the Company's stockholders:

          (a) by the mutual written consent of the Company and Parent;

          (b) by either the Company or Parent, if the Merger has not been
     consummated by December 31, 2001, or such other date, if any, as the
     Company and Parent shall agree upon; provided, that the party seeking to
     terminate this Agreement pursuant to this Section 7.1(b) shall not have
     breached in any material respect its obligations under this Agreement in
     any manner that shall have been the proximate cause of, or resulted in, the
     failure to consummate the Merger by such date; and provided further,
     however, that, if a request for additional information is received from the
     U.S. Federal Trade Commission ("FTC") or Department of Justice ("DOJ")
     pursuant to the HSR Act or additional information is requested by a
     governmental authority (a "Foreign Authority") pursuant to Foreign Merger
     Laws, such date shall be extended to the later of (i) the date set forth
     above or (ii) the 90th day following acknowledgment by the FTC, DOJ, or
     Foreign Authority, as applicable, that Parent and the Company have complied
     with such request, but in any event not later than March 31, 2002;

          (c) by either Parent or the Company if a court of competent
     jurisdiction or an administrative, governmental, or regulatory authority in
     the United States or the European Union has issued a final nonappealable
     order, decree, or ruling, or taken any other action, having the effect of
     permanently restraining, enjoining, or otherwise prohibiting the Merger;

          (d) by Parent, if (i) the Company has breached its obligations under
     Section 5.5 in any material respect; or (ii) the Board of Directors of the
     Company shall have withdrawn or modified or amended in any respect adverse
     to Parent or Merger Sub its approval or recommendation of the Merger; or
     (iii) the Board of Directors of the Company shall have recommended to the
     stockholders of the Company any Acquisition Proposal or shall have resolved
     or announced an intention to do so; or (iv) a tender offer or exchange
     offer for 50% or more of the outstanding shares of the Company Common Stock
     is announced or commenced and either (A) the Board of Directors of the
     Company recommends acceptance of such tender offer or exchange offer by its
     stockholders or (B) within ten (10) business days of such commencement, the
     Board of Directors of the Company shall have failed to recommend against
     acceptance of such tender offer or exchange offer by its stockholders;

          (e) by either the Company or Parent, if the adoption of this Agreement
     by the Company's stockholders as required under applicable law shall not
     have been obtained at the Company Stockholders' Meeting; except that the
     right to terminate this Agreement under this Section 7.1(e) will not be
     available to any party whose failure to perform any obligation under this
     Agreement has been the proximate cause of, or resulted in, the failure to
     obtain the requisite vote of the stockholders of the Company; or

          (f) by the Company prior to the adoption of this Agreement by the
     Company's stockholders if (i) it has complied with, and continues to comply
     with, all requirements, conditions and procedures of Section 5.5 in all
     material respects, (ii) the Board of Directors of the Company has (upon the
     recommendation of the Company's Special Committee) authorized, subject to
     complying with the terms of this Agreement, the Company to enter into a
     binding written agreement concerning a transaction that constitutes a
     Superior Proposal and the Company notifies Parent in writing that it
     intends to enter into such binding agreement, which notice must have
     attached to it the most current version of such agreement, (iii) Parent
     does not make, within five business days after receipt of such notice from
     the Company, any offer that the Company's Special Committee reasonably and
     in good faith determines, after consultation with its financial and legal
     advisors, is at least as favorable to the stockholders of the Company as
     the Superior Proposal and during such five business-day period the Company
     reasonably considers and discusses in good faith all proposals submitted by
     Parent and, without limiting the foregoing, meets with, and causes its
     financial advisors and legal advisors to meet with, Parent and its

                                       A-31
   32

     advisors from time to time as requested by Parent to reasonably consider
     and discuss in good faith Parent's proposals, and (iv) prior to or
     concurrently with the Company's termination pursuant to this Section
     7.1(f), the Company pays to Parent the fee required by Section 7.3 to be
     paid to Parent in the manner therein provided. The Company agrees (x) that
     it will not enter into a binding agreement referred to in clause (ii) above
     until at least the sixth business day after Parent has received the notice
     to Parent required by clause (ii) above, and (y) to notify Parent promptly
     if its intention to enter into the binding agreement included in its notice
     to Parent shall change at any time after giving such notice;

          (g) by Parent if (i) Parent is not in material breach of its
     obligations under this Agreement and (ii) there has been a material breach
     by the Company of any of its representations, warranties, or obligations
     under this Agreement such that the conditions in Section 6.3 will not be
     satisfied ("Terminating Company Breach"); provided, however, that, if such
     Terminating Company Breach is curable by the Company through the exercise
     of commercially reasonable efforts and such cure is reasonably likely to be
     completed prior to the applicable date specified in Section 7.1(b), then
     for so long as the Company continues to exercise commercially reasonable
     efforts, Parent may not terminate this Agreement under this Section 7.1(g);
     or

          (h) by the Company if (i) the Company is not in material breach of its
     obligations under this Agreement and (ii) there has been a material breach
     by Parent of any of its representations, warranties, or obligations under
     this Agreement such that the conditions in Section 6.2 will not be
     satisfied ("Terminating Parent Breach"); provided, however, that, if such
     Terminating Parent Breach is curable by Parent through the exercise of
     commercially reasonable efforts and such cure is reasonably likely to be
     completed prior to the applicable date specified in Section 7.1(b), then
     for so long as Parent continues to exercise commercially reasonable
     efforts, the Company may not terminate this Agreement under this Section
     7.1(h).

     SECTION 7.2  Effect of Termination. The party desiring to terminate this
Agreement shall give written notice of such termination to the other party.
Except for any willful breach of this Agreement by any party hereto (which
willful breach and liability therefor shall not be affected by the termination
of this Agreement or the payment of any Termination Fee (as defined in Section
7.3(a) hereof)), if this Agreement is terminated pursuant to Section 7.1 hereof,
then this Agreement shall become void and of no effect with no liability on the
part of any party hereto; provided, however that notwithstanding such
termination the agreements contained in Sections 5.2, 5.4(b), 7.2, 7.3, 7.4 and
Article VIII hereof shall survive the termination hereof.

     SECTION 7.3  Fees.

     (a) The Company agrees to pay Parent in immediately available funds by wire
transfer to an account designated by Parent an amount equal to One Hundred Eight
Million Dollars ($108,000,000) (the "Termination Fee") if:

          (i) this Agreement is terminated by Parent pursuant to Section 7.1(d)
     (ii) through (iv) hereof; or

          (ii)(A) this Agreement is terminated by Parent or the Company pursuant
     to Section 7.1(b), 7.1(d)(i) or 7.1(e) hereof, (B) at or prior to the time
     of such termination, an Acquisition Proposal with respect to the Company
     shall have been made public and remains pending at the time of such
     termination or at the time of the Company Stockholders' Meeting, and (C)
     within twelve months after such termination, the Company shall enter into a
     definitive agreement with respect to any Acquisition Proposal or the
     transaction contemplated by any Acquisition Proposal relating to the
     Company shall be consummated; or

          (iii) this Agreement is terminated by the Company pursuant to Section
     7.1(f) hereof.

     (b) The Company shall pay the Termination Fee required to be paid pursuant
to Section 7.3(a) hereof (if all conditions thereto have been satisfied) (i)
prior to or concurrently with the termination of this Agreement by the Company,
(ii) not later than one business day after the termination of this Agreement by
Parent, or (iii) in the case of a fee payable pursuant to Section 7.3(a)(ii),
prior to the earlier of the execution

                                       A-32
   33

of the definitive agreement with respect to, or the consummation of the
transaction contemplated by, the applicable Acquisition Proposal.

     SECTION 7.4  No Penalty; Costs of Collection. The Company acknowledges that
the agreements contained in Section 7.3 are an integral part of the transactions
contemplated by this Agreement and are not a penalty, and that, without these
agreements, Parent would not enter into this Agreement. If the Company fails to
pay promptly the fee due pursuant to this Section 7.3, the Company shall also
pay to Parent Parent's costs and expenses (including legal fees and expenses) in
connection with any action, including the filing of any lawsuit or other legal
action, taken to collect payment, together with interest on the amount of the
unpaid fee under this section, accruing from its due date, at an interest rate
per annum equal to the prime commercial lending rate quoted by Wells Fargo Bank
Minnesota, N.A.; provided, however, that Parent shall pay to the Company the
Company's costs and expenses (including legal fees and expenses) incurred in
connection with any such legal action if Parent's claims against the Company in
such legal action do not prevail. Any change in the interest rate hereunder
resulting from a change in such prime rate shall be effective at the beginning
of the date of such change in such prime rate.

not be deemed waived or otherwise affected by any investigation made by any

subsequent to the Effective Time, shall survive the Merger in accordance with
their terms.

     SECTION 8.3  Interpretation. Whenever the words "include," "includes" or

the words, "but not limited to." As used in this Agreement, the term "affiliate"

Act.

     The article and section headings contained in this Agreement are solely for
the purpose of reference, are not part of the agreement of the parties hereto
and shall not in any way affect the meaning or interpretation of this Agreement.

shall not be deemed to be an admission or representation as to the materiality
of the item so disclosed.

     SECTION 8.4  Amendments, Modification and Waiver.

     (a) Except as may otherwise be provided herein, any provision of this
Agreement may be amended, modified or waived by the parties hereto, by action
taken by or authorized by their respective Board of Directors, prior to the
Closing Date if, and only if, such amendment or waiver is in writing and signed,
in the case of an amendment, by the Company and Parent or, in the case of a
waiver, by the party against whom the waiver is to be effective; provided that
after the adoption of this Agreement by the stockholders of the Company, no such
amendment shall be made except as allowed under applicable law.

     (b) No failure or delay by any party in exercising any right, power or
privilege hereunder shall operate as a waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
provided shall be cumulative and not exclusive of any rights or remedies
provided by law.

     SECTION 8.5  Successors And Assigns. The provisions of this Agreement shall
be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns; provided that neither the Company nor Parent
may assign, delegate or otherwise transfer any of its rights or obligations
under this Agreement without the consent of the other parties hereto.

     SECTION 8.6  Specific Performance. The parties acknowledge and agree that
any breach of the terms of this Agreement would give rise to irreparable harm
for which money damages would not be an adequate remedy and accordingly the
parties agree that, in addition to any other remedies, each shall be entitled to
enforce the terms of this Agreement by a decree of specific performance without
the necessity of proving the inadequacy of money damages as a remedy.

     SECTION 8.7  Governing Law and Venue. This Agreement shall be governed by
and construed in accordance with the laws of the State of Delaware (regardless
of the laws that might otherwise govern under applicable principles of conflicts
of laws thereof) as to all matters, including matters of validity, construction,
effect, performance and remedies. The parties hereby (i) agree and consent to be
subject to the exclusive jurisdiction of any state or federal court in the State
of Delaware with respect to all actions and proceedings

                                       A-34
   35

arising out of or relating to this Agreement (and each party agrees not to bring
any such action or proceeding in any other jurisdiction to which the other party
is subject); (ii) agree that all claims with respect to any such action or
proceeding may be heard and determined in such court; (iii) irrevocably waive
any defense of an inconvenient forum to the maintenance of any action or
proceeding in such court; (iv) consent to service of process by mailing or
delivering such service to the party at its respective principal business
address; and (v) agree that a final judgment in any such action or proceeding
from which there is no further appeal shall be conclusive and may be enforced in
any other jurisdictions by suit on the judgment or in any manner provided by
law.

     SECTION 8.8  Severability. If any term or other provision of this Agreement
is invalid, illegal or incapable of being enforced by any rule of law, or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated herein are not affected in any manner materially
adverse to any party hereto. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in a mutually acceptable
manner.

     SECTION 8.9  Third Party Beneficiaries. This Agreement is solely for the
benefit of the Company and its successors and permitted assigns, with respect to
the obligations of Parent and Merger Sub under this Agreement, and for the
benefit of Parent and Merger Sub, and their respective successors and permitted
assigns, with respect to the obligations of the Company under this Agreement,
and this Agreement shall not, except to the extent necessary to enforce the
provisions of Article I and Section 5.6 and 5.11 hereof be deemed to confer upon
or give to any other third party any remedy, claim, liability, reimbursement,
cause of action or other right.

     SECTION 8.10  Entire Agreement. This Agreement, including any exhibits or
schedules hereto and the Confidentiality Agreement constitute the entire
agreement among the parties hereto with respect to the subject matter hereof and
supersedes all other prior agreements or understandings, both written and oral,
between the parties or any of them with respect to the subject matter hereof.

     SECTION 8.11  Counterparts; Effectiveness. This Agreement may be signed in

                         AGREEMENT TO FACILITATE MERGER

DATE:
- ---------------, 2001

PARTIES:

          Medtronic, Inc.,                                (hereinafter "Parent")
          a Minnesota corporation

               and

- ------------------------, an individual officer and/or director
          of MiniMed Inc.                        (hereinafter "Security Holder")

RECITALS:

     A.  Security Holder is the legal or beneficial owner of shares of Common
Stock of MiniMed Inc., a Delaware corporation (the "Company"), and/or the holder
of options, warrants, or other rights to acquire shares of Company Common Stock.

     B.  Parent, the Company, and a wholly-owned subsidiary of Parent are
entering, or have entered, into an Agreement and Plan of Merger (the "Merger
Agreement") pursuant to which it is proposed that Parent's subsidiary will merge
with and into the Company (the "Merger") and as a result of which the
outstanding shares of Company Common Stock shall be converted into the right to
receive a cash payment.

     C.  Security Holder deems it to be in Security Holder's best interest and
in the best interests of the Company and all other stockholders of the Company
that the Merger Agreement be approved, ratified, and confirmed by the
stockholders of the Company, and it is a condition to Parent's obligations under
the Merger Agreement that Security Holder enter into this Agreement.

     D.  It is understood and acknowledged by Security Holder that Parent's
execution of the Merger Agreement is being done in reliance, in part, upon the
contemporaneous execution and delivery of this Agreement, that Parent will incur
substantial expenses proceeding toward consummation of the Merger as
contemplated by the Merger Agreement, and that such expenses will be undertaken,
in part, in reliance upon and as a result of the agreements and undertakings of
Security Holder set forth herein.

     NOW, THEREFORE, in consideration of the foregoing, and in order to induce
Parent to execute the Merger Agreement and to proceed as contemplated by the
Merger Agreement toward the consummation of the Merger, and for other good and
valuable consideration, the receipt and adequacy of which is hereby
acknowledged, the parties hereto agree as follows:

AGREEMENTS:

     1. Vote in Favor of Merger. During the period commencing on the date hereof
and terminating upon the earlier of (i) the effective time of the Merger, and
(ii) the termination of the Merger Agreement in accordance with its terms,
Security Holder agrees to vote (or cause to be voted) all shares of Company
Common Stock presently beneficially owned by Security Holder, and all shares of
Company Common Stock with respect to which Security Holder in the future
acquires beneficial ownership, at any meeting of the stockholders of the
Company, and in any action by written consent of the stockholders of the
Company, in favor of the approval, consent, and ratification of the Merger
Agreement and the Merger and against any proposal or action that could impede,
interfere, frustrate, nullify or discourage the Merger, could facilitate an
acquisition of the Company, in any manner, by a party (other than Parent), or
could reasonably result in any of the conditions to the Company's obligations
under the Merger Agreement not being fulfilled. To the extent inconsistent with
the foregoing provisions of this Section 1, Security 1-folder hereby revokes any
and all previous proxies with respect to any shares of Company Common Stock that
Security Holder owns or has the

                                       A-41
   42

right to vote. Nothing in this Agreement shall be deemed to restrict or limit
Security Holder's right to act in his capacity as an officer or director of the
Company consistent with his fiduciary obligations in such capacity.

     2. Representations and Warranties of Security Holder. Security Holder
represents and warrants to Parent that Security Holder has the legal capacity to
enter into and perform all of Security Holder's obligations under this
Agreement. The execution, delivery, and performance of this Agreement by
Security Holder will not violate any other agreement to which Security Holder is
a party, including, without limitation, any voting agreement, stockholders
agreement, or voting trust. This Agreement has been duly executed and delivered
by Security Holder and constitutes a legal, valid, and binding agreement of
Security Holder, enforceable in accordance with its terms, except as the
enforcement thereof may be limited by bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium, and similar laws, now or hereafter in
effect.

     3. Successors and Assigns. This Agreement shall be binding upon any
purchasers, donees, pled gees, and other transferees of Company Common stock
legally or beneficially owned by Security Holder. During the period commencing
on the date hereof and terminating upon the earlier of the effective time of the
Merger and the termination of the Merger Agreement in accordance with its terms,
Security Holder agrees not to make any sales, gifts, transfers, pledges, or
other dispositions of Company Common Stock without first making any such
transferee or pledgee fully aware of Security Holder's obligations under this
Agreement and obtaining such transferee's or pledgee's written agreement to
comply with all terms hereof.

     4. Injunctive Relief. Security Holder agrees that in the event of Security
Holder's breach of any provision of this Agreement, Parent may be without an
adequate remedy at law. Security Holder therefore agrees that in the event of
Security Holder's breach of any provision of this Agreement, Parent may elect to
institute and prosecute proceedings in any court of competent jurisdiction to
enforce specific performance or to enjoin the continuing breach of such
provision, as well as to obtain damages for breach of this Agreement. By seeking
or obtaining any such relief, Parent will not be precluded from seeking or
obtaining any other relief to which it may be entitled.

     5. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original and all of which
together shall constitute one and the same document.

     6. Further Assurances. Security Holder shall execute and deliver such
additional documents and take such further action as may be necessary or
desirable to consummate the transactions contemplated by this Agreement.

     7. Third-Party Beneficiaries. Nothing in this Agreement, expressed or
implied, shall be construed to give any person other than the parties hereto any
legal or equitable right, remedy. or claim under or by reason of this Agreement
or any provision contained herein.

     8. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware (regardless of the laws that
might otherwise govern under applicable Delaware principles of conflicts of
laws).

     9. Effectiveness. If this Agreement is executed by Security Holder prior to
the approval of the Merger Agreement by the Company's Board of Directors, then
this Agreement shall be subject to, and shall become effective only upon, the
approval of the Merger Agreement by the Company's Board of Directors and the
execution and delivery of the Merger Agreement by the Company, Parent and
Parent's subsidiary. This Agreement shall terminate upon termination of the
Merger Agreement in accordance with its terms.

                                       A-42
   43

     IN WITNESS WHEREOF, Parent has caused this Agreement to Facilitate Merger
to be executed by its duly authorized officer, and Security Holder has executed
this Agreement, as of the date and year first above written.
