ITEM 2.   Acquisition or Disposition of Assets.

          On July 8, 1998, Nitinol Medical Technologies, Inc. (the "Company" or
the "Registrant") completed its acquisition of the neurosurgical instruments
business (the "Business") of Elekta AB (PUBL), a Swedish corporation ("Seller"
or "Elekta"), comprised of (i) assets and (ii) all of the outstanding capital
stock of certain Elekta affiliates, including Elekta Instruments Ltd., a
corporation formed under the laws of the United Kingdom, Elekta Implants S.A., a
French corporation, Elekta Instruments SARL, a French corporation, Elekta
Holding S.A., a French corporation, Elekta Instruments N.V./S.A., a Belgian
corporation, Elekta Instruments S.A., a Spanish corporation, Elekta Instruments
B.V., a Netherlands corporation, Cordis Innovasive Systems, Inc., a Florida
corporation, Spembly Medical Ltd., a corporation formed under the laws of the
United Kingdom, Swedemed AB, a Swedish corporation and Spembly Cryosurgery
Limited, a corporation formed under the laws of the United Kingdom, for
approximately U.S. $33 million in cash pursuant to a Purchase Agreement, dated
as of May 8, 1998 (the "Purchase Agreement"), between the Company and Elekta
(the "Purchase"). In addition, the Company assumed substantially all the
liabilities of the Business as part of the Purchase.

          The Purchase Agreement contains customary representations and
warranties from Elekta and the Company and post-closing covenants including
business support services to be provided by Elekta, non-solicitation and non-
hiring of former Elekta employees hired by the Company and indemnification for
breach of representations and warranties. The terms of the Purchase were
determined on the basis of arm's-length negotiations.

          Prior to the acquisition, the Business was operated as a division of
the Swedish medical technology group of Elekta and derived sales from a broad
range of specialty implants and instruments for neurosurgery. The Company
currently intends to continue the Business substantially in the manner conducted
by Elekta immediately prior to the Acquisition.

          The acquisition was approved by the Board of Directors of the Company,
and by the Board of Directors and the stockholders of Elekta. Prior to the
execution of the Purchase Agreement, neither the Company nor any of its
affiliates, nor any director or officer of the Company or any associate of any
such director of officer, had any material relationship with Elekta.

          The Purchase was financed with $13 million of the Company's cash and
$20 million of subordinated debt from an affiliate of J.H. Whitney & Co., a
significant stockholder of the Company. The subordinated debt is secured by
substantially all of the assets of the Company and is due September 30, 2003,
with interest payable quarterly at 10.101% per annum. A total of 675,000 shares
of the Company's common stock were issued to J.H. Whitney & Co., and its
affiliates in connection with the transaction. The shares are accompanied by
certain demand and "piggy-back" registration rights. The purchase price for the
shares was $5.80, representing the closing

                                       2
<PAGE>
 
price of the Company's common stock as reported by the Nasdaq National Market on
July 7, 1998, discounted by 20%. Of the 675,000 shares, 113,793 shares were 
issued to J.H. Whitney & Co. as a transaction fee. In addition, the Company paid
J.H. Whitney & Co. a debt placement fee of $600,000.

          Junewicz & Co. acted as the Company's financial advisor in connection
with the Acquisition and the financing and issued fairness opinions with respect
thereto.

          The foregoing description of the Purchase Agreement does not purport 
to be complete and is qualified in its entirety by reference to the full text of
the Purchase Agreement which is filed as Exhibit 2.1 to this Current Report on 
Form 8-K and incorporated herein by reference.

the amount of USD 500,000 as a termination fee.

          (c)  On the Closing Date, Buyer shall divide and pay the Purchase
Price to and among Seller and its Affiliates in such portions as Seller may
designate, such payments to be made by wire transfers of funds from banks
selected by Buyer to banks selected by Seller. Prior to the Closing Date, Buyer
and Seller shall use their best efforts to agree on the allocation of the
Purchase Price among the Assets.

          (d)  Notwithstanding the provisions of subsection 2.2(c) hereof, if
the Closing Net Worth shall not have been finally determined by the Closing
Date, the Closing shall nevertheless take place if the amount which Buyer
asserts to be the correct amount for the Closing Net Worth (the "Buyer's Closing
Net Worth Amount") would result in a Purchase Price Adjustment of no more than
USD 1,500,000, and in such event the following rules shall apply:

               (i)  At Closing, Buyer shall pay an amount (the "Provisional
Purchase Price") equal to what the Purchase Price would be if the Buyer's
Closing Net Worth Amount is the correct amount for the Closing Net Worth; and

               (ii) Promptly after the Closing Net Worth is finally determined
in accordance with subsection 2.2 (a), Buyer shall pay to Seller the amount, if
any, by which the Purchase Price exceeds the Provisional Purchase Price.

     2.3  ASSUMPTION OF LIABILITIES. Buyer shall assume at the Closing (a) the
          -------------------------
Closing Balance Sheet items listed on Exhibit 2.3 A, (b) the obligations of the
Companies under the contracts listed on Exhibit 3.9, all of which shall be
assumed pursuant to an assignment of contracts, and assumption of liabilities in
the form attached hereto as Exhibit 2.3 (the "Assignment and Assumption
Agreement"), and (c) the other obligations and liabilities described on Exhibit
2.3A (collectively the "Assumed Liabilities"). Buyer shall perform all
obligations related to the Assumed Liabilities. After Closing, Seller shall have
no responsibility to the Buyer or the Acquired Companies for the Assumed
Liabilities of the Companies except for any liability attributable to a
violation of any Environmental Law(s) by the Business prior to the Closing or
the Release of any Hazardous Materials prior to the Closing ("Excluded
Environmental Liabilities"). Buyer's assumption of the Assumed Liabilities
relating to the Acquired Companies is intended solely for the benefit of Seller
and its Affiliates and is not intended to create rights for any other parties.

     2.4  INSTRUMENTS OF TRANSFER AND ASSUMPTION.
          --------------------------------------

          (a)  Seller shall deliver to Buyer at the Closing such endorsed share
certificates, stock transfer forms, bills of sale, assignments of lease, deeds,
assignments of lease, licenses and other instruments of assignment and transfer,
in form reasonably satisfactory to Buyer, as shall be effective to convey to
Buyer all of Seller's right, title and interest in and to each of the Assets.

          (b)  Buyer shall deliver to Seller at the Closing such instruments of
assumption, in form reasonably satisfactory to Seller, as shall be effective to
assure Seller that Buyer will perform all obligations related to the Assumed
Liabilities, including without limitation the Assignment and Assumption
Agreement.

     2.5  CONSENTS.
          --------

          (a)  Buyer and Seller shall cooperate in securing before and after the
Closing all consents with respect to the sales and transfers of the Assets from
each governmental authority whose consent is necessary to such sales and
transfers.

          (b)  The Seller, the Companies and any other relevant Affiliates of
Seller shall use their reasonable commercial efforts to obtain the waiver,
consent and approval of all non-governmental persons whose waiver, consent or
approval (i) is required in order to consummate the transactions contemplated by
this Agreement or (ii) is required by any material agreement, lease, mortgage or
security instrument, arrangement, judgment, decree, order, permit or license to
which Seller or any of the Companies is a party or subject on the Closing Date
and (A) which would prohibit, or require the waiver, consent or approval of any
person to such transactions or (B) under which, without such waiver, consent or
approval, such transactions would constitute an occurrence of default under the
provisions thereof, result in the acceleration of any obligation thereunder or
give rise to a right of any party thereto to terminate its obligations
thereunder.

          (c)  Nothing in this Agreement shall be deemed to constitute or
require an assignment or an attempt to assign any contract or other agreement
with any third party if the attempted assignment thereof without the consent of
any such third party would constitute a breach thereof or adversely affect in
any way the rights of Seller and its assignee thereunder. If,

                                       8
<PAGE>
 
after Seller shall have used reasonable efforts to obtain such consents from any
such third party, any such consent shall not have been obtained at or prior to
the Closing, or the attempted assignment of such contract or agreement without
such consent at the Closing would have an adverse effect on such rights or Buyer
would not in fact receive such rights, Seller shall cooperate with Buyer, at
Buyer's expense, in any reasonable arrangement designed to provide for Buyer the
benefits thereunder, including enforcing for the benefit of Buyer any or all
rights of Seller against any such third party arising out of the breach or
cancellation thereof by any such third party or otherwise. Provided, however,
                                                           --------  -------
Buyer shall not be obligated to close until Seller has obtained all consents of
third parties which are required for the assignment of those contracts listed on
Exhibit 2.5 hereto (the "Critical Contracts").



     2.6  FURTHER ASSURANCES. Buyer and Seller shall each, from time to time
          ------------------
after the Closing, at the request of the other and without further
consideration, execute and deliver such further instruments of assignment,
transfer, license or assumption and take such further action as the other may
reasonably request in order more effectively to transfer, reduce to possession
and record title to any of the Assets, or to implement the assumption of the
Assumed Liabilities. Reasonable out of pocket expenses incurred in compliance
with this Section by one party at the request of the other party shall be
promptly reimbursed by the requesting party to the party incurring such
expenses.

     2.7  SALES AND TRANSFER TAXES; FEES. All applicable sales, transfer,
          ------------------------------
registration, documentary, use, filing and other taxes (other than income taxes)
and other governmental (and notarial) fees that may be levied or are otherwise

hereunder, whether levied on or payable by Seller or Buyer, shall be divided
equally between Buyer and Seller, and Buyer and Seller shall each pay one-half
(1/2) thereof.

3.   REPRESENTATIONS AND WARRANTIES OF SELLER. Seller represents and warrants to
     ----------------------------------------
Buyer as follows.

     3.1  SELLER'S ORGANIZATION, POWER, EXECUTION.
          ---------------------------------------

          (a)  Each of Seller and the Companies is a corporation duly organized,

incorporation and has all requisite power and authority (corporate and other) to
own its properties, to carry on its business as now being conducted, to execute,
and deliver this Agreement and the agreements contemplated herein and to carry
out the transactions contemplated hereby and thereby. Each of the Companies is
duly qualified to do business and in good standing in all jurisdictions in which
its ownership of property or the character of its business requires such
qualification, except where the failure to be qualified in the case of any such
Company would not have a material adverse effect on the business or assets of
such Company. Certified copies of the charter and bylaws or other governing
documents of the Seller and each of the Acquired Companies, as amended to date,
have been previously delivered to the Buyer, are complete and correct, and no
amendments have been made thereto or have been authorized since the date
thereof.

          (b)  The execution and delivery of this Agreement and the agreements
provided for herein and the consummation of all transactions contemplated hereby
and thereby have been duly authorized by all necessary corporate action on the
part of Seller, and this Agreement has been duly executed and delivered by
Seller and constitutes, and each other

                                       9
<PAGE>
 
document and instrument required hereby to be executed and delivered to Buyer
will when delivered constitute, the valid and legally binding obligation of
Seller or its relevant Affiliate enforceable in accordance with its terms,
subject to bankruptcy laws and general equitable principles. The execution and
delivery of this Agreement and performance of the transactions contemplated
hereby will not with or without the giving of notice or the passage of time or
both, conflict with, result in a breach, violation or termination of any term or
provision by Seller or any of the Companies of, or constitute a default by
Seller or any of the Companies under, any agreement, instrument or order to
which Seller or any of the Companies is a party or by which Seller or any of the
Companies is bound or the corporate charter or by-laws or other governing
documents of Seller or any of the Companies, or any statute, judgment, order,
award, injunction, decree, regulation or ruling of any court, governmental
authority or arbitrator, or cause any acceleration under, or cause the creation
of any lien, charge or encumbrance upon the properties or assets of the Seller
or any of the Companies pursuant to, any indenture, mortgage, deed of trust or
other instrument or agreement to which the Seller or any of the Companies is a
party or by which the Seller or any of the Companies or any of their respective
properties is or may be bound.

     3.2  RIGHT TO TRANSFER. Seller and its Affiliates have the right to
          -----------------
transfer the Assets to Buyer and/or its Affiliates, subject to the consents
referred to in Subsections 2.5(b) and 2.5(c).

     3.3  GOVERNMENTAL COMPLIANCE. Each of Seller and the Companies has the
          -----------------------
corporate power and authority and all licenses and permits: (i) which are
required by governmental authorities to own and operate the Business and to
carry on the Business as now being conducted and (ii) whose absence would have a
material adverse effect on the Business (the "Authorizations"). The
Authorizations are in full force and effect. All of the Products comply, and
have been manufactured, marketed and sold in compliance, in all material
respects with all applicable laws and regulations. None of the Companies have
reasonable grounds to believe that any of the Authorizations will not in the
ordinary course be renewed or continued. To the knowledge of the Companies, the
current operation of the Business is not in material violation of any applicable
statute, ordinance, regulation or administrative or judicial order or ruling.

     3.4  NOTICES OF VIOLATION. None of the Companies has received any written
          --------------------
claim or written assertion that there has been any breach of any of the terms or
conditions of any Authorizations (or has knowledge of any threat thereof) in
such manner (a) as would permit any other party to cancel, terminate or
materially amend any Authorization, or (b) that any such breach or breaches
singly or in the aggregate could materially and adversely affect the financial
condition or results of operations of the Business. None of the Companies has
received any written notice requiring the accumulation and submission of
substantial clinical data necessary to establish the safety and effectiveness of
any Product not previously required or imposing any other material condition or
requirement restricting the continued commercial distribution of such Product.

     3.5  DEFAULTS. Neither the execution and delivery of this Agreement nor the
          --------
carrying out of any of the provisions hereof or the transactions contemplated
hereby will result in the creation or imposition of any security interest, lien,
claim, charge, or other encumbrance of any nature whatsoever upon any of the
Assets after the Closing Date.

     3.6  FINANCIAL STATEMENTS AND CHANGES.
          --------------------------------

          (a) The Balance Sheet was prepared in accordance with Swedish GAAP
(insofar as applicable to the description of a portion of a business). The
Balance Sheet reflects all liabilities of the Business, whether absolute,
contingent, accrued or otherwise existing as of the date thereof which are of a
nature required to be reflected in financial statements prepared in accordance
with Swedish GAAP. The Income Statement was prepared in accordance with Swedish
GAAP (insofar as applicable to the description of a portion of a business). The
Balance Sheet and the Income Statement fairly present, in all material respects,
the financial condition and results of operations, respectively, of the Business
at the date of such Balance Sheet and for the ten month period covered by the
Income Statement. If the Balance Sheet and Income Statement had been prepared in
accordance with International Accounting Standards instead of Swedish GAAP, they
would not be materially different, except for possible differences attributable
to: (i) group adjustments for restructuring provisions, acquisition goodwill and
consolidation; (ii) treatment of pension plan overfunding or underfunding; and
(iii) valuation of intellectual property. Except as reflected in the Balance
Sheet or as disclosed on Exhibit 1.10 and Exhibit 3.9, the Companies are not in
default with respect to any material liabilities or obligations, and any
liabilities incurred or accrued subsequent to the date of the Balance Sheet have
been, or are being, paid and discharged in the normal course as they become due,
and all such liabilities and obligations were incurred in the ordinary course of
business except as indicated on Exhibit 1.10.

          (b) Since the date of the Balance Sheet, there has been (a) no change
in the financial condition, assets, liabilities or business of the Business or
the Assets which has had a material adverse effect on the Business; (b) no
damage, destruction or loss (whether or not covered by insurance) materially
adversely affecting the Business or the Assets; (c) no labor trouble materially
adversely affecting the Business or the Assets; (d) no sale or transfer of any
Assets, except sales in the ordinary course of business; (e) no imposition of
any material lien, charge, encumbrance (which as used herein includes, without
limitation, any mortgage, deed of trust, conveyance to secure debt or security
interest) or claim upon any of the Assets, except for statutory landlord's liens
with respect to rent not yet due and payable and any current year lien with
respect to personal or real property taxes not yet due and payable; (f) no
default in any liability or obligation which would have a material adverse
effect on the Business; (g) no agreement by any of the Companies to any material
adverse change in the terms of any material contract or instrument to which it
is a party; or (h) no waiver, cancellation or disposal by any of the Companies
of, for less than the face amount thereof, any material claim or right which it
has against others; (i) no transaction or event which would materially increase
the tax liability of any of the Acquired Companies for any prior taxable year or
the tax liability of any of the Companies for any prior taxable year for which
Purchaser, the Assets, or any of the Acquired Companies would become liable; (j)
no payment of any dividend or other distribution to a shareholder by any of the
Acquired Companies; or (k) no transaction other than in the ordinary course of
business which can be reasonably expected to have a material adverse effect on
the Business.

     3.7  TAX CONSOLIDATION. None of the Acquired Companies has ever been a
          -----------------
member of an "affiliated group" of corporations (within the meaning of Section
1504 of the Code), other than the group of which Elekta Holding U.S., Inc. is
the common parent and, previously, the groups of which Cordis Corporation and
Johnson & Johnson were the common parents. Neither CIS nor any member of any
"affiliated group" of which Elekta Holdings U.S., Inc. is the common parent has
any outstanding waivers or extensions of any applicable statute of limitations
relating to the assessment of Taxes. An election under Treasury Reg. Section
1.1502-20(g) has not been

                                       11
<PAGE>
 
made with respect to CIS by Elekta Holdings U.S., Inc. A basis reduction
pursuant to Treasury Reg. Section 1.1502-20(b) or Treasury Reg. Section
1.337(d)-2T(b) has not been required to be made with respect to CIS with respect
to any period during which CIS has been a member of the "affiliated group" of
which Elekta Holdings U.S., Inc. is the common parent. CIS does not have any
actual or potential liability for any Tax obligation of any other taxpayer
(including without limitation any affiliated group of corporations or other
entities that included CIS during a prior period).

     3.8  TAX RETURNS. Each of the Companies has, as of the date hereof, and 
          -----------
will prior to Closing have, timely and accurately filed all Tax Returns required
to be filed by it prior to such dates and has timely paid, and will on the
Closing Date be current in the payment and remittance of all Taxes. None of the
Companies is, or will become, subject to any additional Taxes as a result of the
failure to file timely or accurately, as required by applicable law, any Tax
Return or to pay timely any amount shown to be due thereon. No written
assessments or notices of deficiency or other communications have been received
by any of the Companies with respect to any Tax Return which has not been paid
or discharged, and no amendments or applications for refund have been filed or
are planned with respect to any such Tax Return. There are no agreements between
any of the Companies and any taxing authority waiving or extending any statute
of limitations with respect to any Tax Return. Save in the ordinary course of
their businesses, none of the Companies has incurred with respect to any period
ending on or prior to the Closing Date any taxable income or liability for
taxes. True and correct copies of the income tax returns for each of the
Acquired Companies for the past three years (or for such portion thereof as each
Acquired Company may have been in existence and may have been owned by Seller)
have heretofore been delivered by Seller to Buyer. None of the Acquired
Companies are parties to any tax sharing agreements. The provisions for Taxes
shown on the Closing Balance Sheet will be adequate to discharge all Taxes
incurred by the Acquired Companies with respect to all periods ending on or
before the Effective Date, including as if the taxable year of each of the
Acquired Companies ended on the Effective Date. Except as set forth in Exhibit
3.8 hereto, none of the Tax Returns of the Acquired Companies has been audited
by any taxing authority within the past three (3) years and no adjustments have
been made to any Tax Returns of the Acquired Companies by any taxing authority
pursuant to any such audit. CIS has not made or is not obligated to make any
payment which will be or may be characterized as an "excess parachute payment"
within the meaning of Section 280G(b)(1) of the Code. CIS has not flied a
consent pursuant to Section 341(f) of the Code nor has CIS agreed to have
Section 341(f)(2) of the Code apply to any disposition of a subsection (f) asset
(as such term is defined in Section 341(f)(4) of the Code). CIS is not and has
not been a United States real property holding corporation within the meaning of
Section 897(c)(2) of the Code during the applicable period specified in Section
897(c)(1)(A)(ii) of the Code.

agreements described in Section 3.10(a) below) consists of a true and complete
list of all material contracts, agreements and other instruments entered into in
respect of the Business); and contemporaneously with or prior to the execution
of this Agreement, Seller has provided Buyer access to a true and complete copy
of each such contract, agreement or instrument which is in writing.

                                       12

          (b) All of the contracts, agreements, policies of insurance or
instruments described on the Schedule of Assets or in Exhibit 3.9 hereto and the
agreements described in Section 3.10(a) below are, except as disclosed on the
Schedule of Assets or Exhibit 3.9 hereto, valid and binding upon the Companies
and the other parties thereto and are in full force and effect and enforceable
in accordance with their terms, and, except as disclosed in Exhibit 3.9, none of
the Companies nor, to the knowledge of the Companies, any other party to any
such contract, commitment or arrangement has breached any material provision of,
the terms thereof. Except as disclosed in Exhibit 3.9, none of the Companies has
received any payment from any contracting party in connection with or as an

Companies consistent with amounts historically charged for such services.

          (c) Exhibit 3.9(c) is a true and complete list of certain contracts
between Seller and/or the Acquired Companies and certain management employees of
the Business pursuant to which such management employees will be paid incentive
compensation upon the sale of the Business and pursuant to which one management
employee is promised certain compensation in the event his employment is
terminated under certain circumstances. Except as indicated on Exhibit 3.9(c),
Buyer shall not be required to assume any obligations of the Seller under the
contracts or arrangements listed on Exhibit 3.9(c).

    3.10  INTELLECTUAL PROPERTY.
          ---------------------

          (a) The Schedule of Assets sets forth a complete and correct list and
summary description of all Company Intellectual Property, together with a
complete list of all material agreements relating thereto, including without
limitation all licenses granted by or to the Companies with respect to any
Company Intellectual Property. Except as disclosed on the Schedule of Assets,
all such Company Intellectual Property is beneficially owned and owned of record
by the Companies, free and clear of all liens, claims, security interests and
encumbrances of any nature whatsoever and constitute all of such items necessary
for the lawful conduct of the Business as now conducted.

          (b) (i) Each Company has, or will have upon Closing, such rights to
use, protect, prosecute, sell, transfer, license, dispose of or bring actions
for the infringement of its rights in and to, and to exclude others from using
the Company Intellectual Property as are established by, the applicable laws of
each relevant jurisdiction (and to the extent provided in each agreement under
which each Company is licensee) to the sole and exclusive owner of an item of
Intellectual Property of such kind; (ii) except as disclosed on the Schedule of
Assets, each Company is the sole beneficial and record owner of its intellectual
property and the Company Intellectual Property which is registered or the
subject of an application for registration (collectively, the "Company
Registered Intellectual Property") has been duly maintained in all material
respects in accordance with the legal and administrative requirements of the
appropriate jurisdictions, and has (except for patents which may have expired on
their normal expiration dates) not lapsed, expired, been canceled or been
abandoned; (iii) no registration or application for registration of any material
item of Company Registered Intellectual Property is the subject of any pending
opposition, interference, cancellation or other legal or governmental proceeding
filed before any governmental authority in any competent jurisdiction.

          (c) Except as disclosed on Exhibit 3.10, none of the Companies is
currently in receipt of any written notice of any violation of, and, to the
knowledge of the Companies,

                                       13
<PAGE>
 
none of Companies (and none of their employees or agents) is infringing,
misappropriating, misusing or violating, the rights of others in any
Intellectual Property. To Seller's knowledge the business of Spembly, SCL and
EIL is not subject to any claim to pay compensation pursuant to Sections 40 and
41 of the Patents Act 1977, and, to the Seller's knowledge, there are not any
facts likely to give rise to such a claim.

     3.11    MISAPPROPRIATION OF INTELLECTUAL PROPERTY. There has been, to the
             -----------------------------------------
knowledge of the Companies, no infringement, unauthorized use or disclosure or

proceeding commenced or induced by a party hereto or by a party claiming a

performance under this Agreement) instituted by or before any court or other
governmental body which could reasonably be expected to materially affect

<PAGE>
 
the right of Buyer to own, operate or control the Business or the Assets

Buyer harmless from and against all direct damages and liabilities including
reasonable attorneys' fees (excluding lost profits and other consequential

arising from the falsity of any representation or warranty of Seller or breach
of any covenant contained in this Agreement by Seller or from any Excluded
Environmental Liabilities.

basis) arising from (j) the falsity of any representation or warranty of the
Buyer or the breach of any covenant contained in this Agreement by Buyer; and
(ii) the Assumed Liabilities except those relating to a breach of a

                                                         --------  -------
survival period for indemnification based on the falsity of Sections 3.8,
3.18.1.1 or 3.l 8.2.2 shall be seven (7) years from the Closing Date, the

the amount of the Purchase Price.

     14.4     CLAIMS FOR INDEMNIFICATION.  Whenever any claim shall arise for
              --------------------------
indemnification hereunder, the party seeking indemnification (the "Indemnified
Party") shall promptly notify the party from whom indemnification is sought (the
"Indemnifying Party") of the claim and, when known, the facts constituting the
basis for such claim. For purposes of this Section 14.4, notice shall be deemed
to be promptly made if it is given to the Indemnifying Party within ten (10)
days of receipt by the Indemnified Party of any written notice of any third
party claim. In the event of any claim for indemnification under this Agreement
resulting from or in connection with any claim or legal proceedings by a third
party, the notice to the Indemnifying Party shall specify, if known, the amount
or an estimate of the amount of the liability arising from such claim or legal
proceeding. Except as provided in Section 14.5 of this Agreement, the
Indemnified Party shall not settle or compromise any claim by a third party for
which it may claim indemnification under this Agreement without the prior
written consent of the Indemnifying Party.

     14.5     DEFENSE BY INDEMNIFYING PARTY.  In connection with any claim by an
              ----------------------------- 
Indemnified Party resulting from or arising out of any claim or legal proceeding
by a person who is not a party to this Agreement, the Indemnifying Party at its
sole cost and expense may, upon written notice to the Indemnified Party, assume
the defense of any such claim or legal proceeding if it acknowledges to the
Indemnified Party in writing its obligation to indemnify the Indemnified Party
with respect to all elements of such claim. The Indemnified Party shall be
entitled to participate in (but not control) the defense of any such action,
with its own counsel and at its own expense. If the Indemnifying Party does not
assume the defense of any such claim or litigation resulting therefrom within 30
days after the date of such claim is made, (a) the Indemnified Party may defend
against such claim or litigation, in such manner as it may deem appropriate,
including, but not limited to, settling such claim or litigation, after giving
notice of the same to the Indemnifying Party, on such terms as the Indemnified
Party may deem appropriate, and (b) the Indemnifying Party shall be entitled to
participate in (but not control) the defense of such action, with its own
counsel and at its own expense.

     14.6     PAYMENT OF INDEMNIFICATION OBLIGATION.  All indemnification
              -------------------------------------
hereunder shall be effected by payment of cash or delivery of a cashier's or
certified check in the amount of the indemnification liability. Any
indemnification payment by Seller to Buyer hereunder shall be deemed to be a
reduction in the Purchase Price.

     14.7     EXCLUSIVE REMEDY.  The rights of indemnification set forth in this
              ----------------
Section 14 and in the U.K. Tax Covenant shall be, from and after the Closing
Date, the exclusive remedy of each party for the breach by the other party of
any representation, warranty, covenant or other term in this Agreement, except
for claims based upon fraud and claims for specific performance or other
equitable relief.

15.  ADDITIONAL ACTIONS.
     ------------------

     15.1     SERVICES.  The parties recognize that in order for Buyer to assume
              -------- 
control of the Business in an orderly manner it may be necessary for Seller to
assist Buyer in the performance of certain business support functions after the
Closing in view of the fact that the Business has not been a freestanding
enterprise. Understanding that Seller is not in the business of providing

                                       29
<PAGE>
 
such support services to others and that Buyer must diligently develop the
capacity to support the Business as soon as practicable after the Closing Date,
the parties shall cooperate during the period from the date hereof to the
Closing Date to identify those areas in which the Business will require support
and to enter into one or more service agreements providing for the rendering of
such support by Seller to Buyer such services to be performed at a reasonable
level and at no charge to the Buyer. The services to be provided by Seller and
the duration of each service are described in Exhibit 15.1 hereto.

     15.2     CHANGE OF NAMES.  As soon as practicable (but no later than thirty
              --------------- 
(30) days) after Closing, Buyer shall cause the name of each of the Acquired
Companies which contains the word "Elekta" to be changed to a name which does
not contain the word "Elekta."

     15.3     RELEASE OF GUARANTEES BY SELLER.  As soon as practicable (but no
              ------------------------------- 
later than thirty (30) days) after Closing, Buyer shall use its best efforts to
cause to be released all guarantees by Seller of the obligations of any of the
Acquired Companies listed on Exhibit 15.3 and pending such release the Buyer
shall indemnify and keep Seller indemnified from and against any and all costs,
claims, demands or liabilities incurred or arising from any such guarantees.

     15.4     ADDITIONAL AGREEMENTS.
              ---------------------

              (a) Proprietary Information.

                  (i)    From and after the Closing Date, the Seller shall hold
in confidence, and use its best efforts to have all of its officers, directors
and personnel and each of the Companies hold in confidence, all knowledge and
information of a secret or confidential nature with respect to the Business and
shall not disclose, publish or make use of the same without the consent of the
Buyer, except to the extent that such information shall have become public
knowledge other than by breach of this Agreement by any of the Companies or to
the extent required by law.

                  (ii)   The Seller agrees that the remedy at law for any breach
of this Subsection 15.4 would be inadequate and that the Buyer shall be entitled
to injunctive relief in addition to any other remedy it may have upon breach of
any provision of this Subsection 15.4.

              (b) Sharing of Data.
                  ---------------  

                  (i)    The Seller shall have the right for a period of three
years following the Closing Date to have reasonable access to such books,
records and accounts, including financial and tax information, correspondence,
production records, employment records and other similar information as are
transferred to the Buyer pursuant to the terms of this Agreement for the limited
purposes of concluding its involvement in the Business prior to the Closing Date
and for complying with its obligations under applicable securities, tax,
environmental, employment or other laws and regulations. The Buyer shall have
the right for a period of three years following the Closing Date to have
reasonable access to those books, records and accounts, including financial and
tax information, correspondence, production records, employment records and
other records which are retained by the Seller pursuant to the terms of this
Agreement to the extent that any of the foregoing relates to the Business
transferred to the Buyer hereunder or is otherwise

                                       30
<PAGE>
 
needed by the Buyer in order to comply with its obligations under applicable
securities, tax, environmental, employment or other laws and regulations.

               (ii) The Seller and the Buyer agree that from and after the
Closing Date they shall cooperate fully with each other to facilitate the
transfer of the Assets from the Seller to the Buyer and the operation thereof by
the Buyer.

          (c)  Cooperation in Litigation. Each party hereto will fully cooperate
               -------------------------
with the other in the defense or prosecution of any litigation or proceeding
already instituted or which may be instituted hereafter against or by such party
relating to or arising out of the conduct of the Business prior to or after the
Closing Date (other than litigation arising out the transactions contemplated by
this Agreement).  The party requesting such cooperation shall pay the out-of-
pocket expenses (including legal fees and disbursements) of the party providing
such cooperation and of its officers, directors, employees and agents reasonably
incurred in connection with providing such cooperation, but shall not be
responsible to reimburse the party providing such cooperation for such party's
time spent in such cooperation or the salaries or costs of fringe benefits or
similar expenses paid by the party providing such cooperation to its officers,
directors, employees and agents while assisting in the defense or prosecution of
any such litigation or proceeding.

          (d)  Conduct of Business between Effective Date and Closing Date by

EII, EIAL, EGBH and Seller
- --------------------------

     (i)  That portion of the Business conducted by EII, EIAL, EGBH and Seller
shall, during the period between the Effective Date and the Closing Date, be
conducted by EII, EIAL, EQBH and Seller for the account of the Buyer.

     (ii) In order to effectuate the agreement set forth in subparagraph (i)
above, Buyer and Seller agree to implement the following procedure:

          (A)  During the period which begins on the Effective Date and ends on
          the Closing Date, EII, EIAL, EGBH and Seller shall receive any
          payments made by customers for Products sold after the Effective Date
          by EII, EIAL, EGBH and Seller (the total amount thus received being
          referred to herein as the "Gross Receipts");

          (B)  During the period which begins on the Effective Date and ends on
          the Closing Date, EII, EIAL, EGBH and Seller shall continue to make
          cash expenditures which are properly allocable to the normal operation
          of the Business in the ordinary course consistent with prior practice
          (but excluding the cost of providing the services described in Exhibit
          15.1) (the total amount thus expended being referred to herein as
          "Gross Expenditures");

          (C)  Fifteen (15) days after the Closing Date, Seller shall deliver to
          Buyer a statement which itemizes the Gross Receipts and the Gross
          Expenditures in reasonable detail, subject to Buyer's right to review
          and dispute such statement. If Gross Receipts exceed Gross
          Expenditures, Seller shall promptly pay to Buyer an amount equal to
          such excess, or, if Gross Expenditures exceed Gross

                                       31
<PAGE>
 
               Receipts, Buyer shall promptly pay to Seller an amount equal to

     -------

     16.1  AFFILIATE INVOLVEMENT. It is understood that both Seller and Buyer
           ---------------------    
conduct parts of their respective businesses through and in conjunction with
Affiliates and are likely to do so in the future. In this Agreement, references
to Affiliates are made in certain provisions for the sake of clarity, but some
repeated references have been avoided because the terms "Seller" and "Buyer" are
intended to encompass the Affiliates of each insofar as that is necessary to
give full effect to the rights and obligations of the parties hereunder and to
prevent results which are anomalous in the context of the transactions
contemplated hereby. The covenant or agreement of a party to do or not to do a
thing is also such party's covenant or agreement to cause its relevant
Affiliates to do or not to do that thing. A covenant, agreement, representation
or warranty for the benefit of a party is also for the benefit of such party's
relevant Affiliates. The act, omission or knowledge of a party's relevant
Affiliate is attributed to the party. Damages suffered by a relevant Affiliate
of a party are also suffered by the party. Buyer shall have the right to require
that certain of the Assets be conveyed at Closing to Affiliates of Buyer
specified by Buyer.

     16.2  PAYMENT OF EXPENSES. Except as specifically set forth elsewhere in
           -------------------  
this Agreement, expenses related to this Agreement and attendant transactions,
including the fees of brokers, counsel and accountants, shall be borne by the
party incurring such expenses. No transaction expenses shall be borne by the
Acquired Companies.

     16.3  MODIFICATIONS; WAIVERS.  This Agreement may be modified and rights
           ----------------------
hereunder may be waived only by a writing executed and delivered on behalf of
the party against whom such modification or waiver is asserted.

     16.4  ASSIGNABILITY. This Agreement and the rights and obligations
           ------------- 
hereunder shall be binding upon and inure to the benefit of the parties hereto
and their respective successors (including successors by operation of law) and
legal representatives. This Agreement shall not be assignable by either party
hereto, except that Seller and Buyer may assign its rights and obligations
hereunder to one or more of its Affiliates, provided that, the assignor shall
                                            ------------- 
guarantee the performance of such assignees under this Agreement and further
provided that if the Affiliate of Buyer to which the Buyer assigns its rights
and obligations under this Agreement ceases to be an Affiliate of Buyer, Buyer
shall cause such former Affiliate to assign its rights and obligations under
this Agreement to Buyer or another Affiliate of Buyer.

           ------------------------
entering into this Agreement it has not relied on any representation, warranty,
agreement or statement not set out in this Agreement (or in any document,
instrument or certificate contemplated hereby), whether express or implied, and
that (in the absence of fraud) it will not have any right or remedy arising out
of any such representation, warranty, agreement or statement.

           --------------------
Affiliates to initiate or participate in any legal proceeding in connection with

controversies or claims on behalf of their Affiliates by arbitration conducted
by the parties in accordance with this Section. The parties shall cause their
Affiliates to comply with any award rendered in an arbitration proceeding
pursuant hereto.

     17.3  ARBITRATION. Any controversy or claim arising out of or relating to

by arbitration in accordance with the Rules of Arbitration of the London Court
of Arbitration by an arbitrator or arbitrators appointed in accordance with said
rules. Judgment upon the award rendered by the arbitral tribunal may be entered
in any court having jurisdiction thereof or application may be made to such
court for judicial acceptance of such award and an order of enforcement, as the
case may be. The place of arbitration shall be London, England, and the language
of the arbitration shall be English. The parties hereby agree that the rendering
of an award by the arbitrator or arbitrators shall be a condition precedent to
the initiation of any legal proceeding with respect to any dispute arising in
connection with this Agreement. Such award shall be final, binding and
enforceable. Each of EHSA and EISA expressly waives its rights to the
jurisdiction of the French courts. The arbitral tribunal shall apply the
substantive laws of the State of Georgia, without regard to the conflicts of
laws principles of the State of Georgia.

agrees, subject to the limitations contained herein, to perform, pay or
discharge when due those liabilities of the Seller and its Affiliates under the
Assigned Contracts.

     4.   Contested Liabilities. Nothing contained herein shall require Buyer to
          --------------------- 
perform, pay or discharge any debts, liabilities or obligations assumed hereby
so long as Buyer shall in good faith contest or cause to be contested and amount
or validity thereof.

     5.   Indemnification. Nothing contained herein shall reduce or otherwise
          ---------------
affect Buyer's rights to be indemnified by the Seller in accordance with the
terms of the Purchase Agreement.

     6.   Consequences of Absence of Consent. Nothing in this Agreement shall be
          ----------------------------------
deemed to constitute or require an assignment or an attempt to assign any
contract or other agreement with any third party if the attempted assignment
thereof without the consent of any such third party would constitute a breach
thereof or adversely affect in any way the rights of

                                       1
<PAGE>
 
Seller and Buyer thereunder. If any such consent has not been obtained at or
prior to the Closing Date, or the attempted assignment of such contract or
agreement without such consent would have an adverse effect on such rights or
Buyer would not in fact receive such rights, Seller shall cooperate with Buyer,
at Buyer's expense, in any reasonable arrangement designed to provide for Buyer
the benefits thereunder, including enforcing for the benefit of Buyer any or all
rights of Seller (or any of its Affiliates) against any such third party arising
out of the breach or cancellation thereof by any such third party or otherwise.

     7.   AFFILIATE INVOLVEMENT. It is understood that both Seller and Buyer
          ---------------------
conduct parts of their respective businesses through and in conjunction with
Affiliates and are likely to do so in the future. In this Agreement, references
to Affiliates are made in certain provisions for the sake of clarity, but some
repeated references have been avoided because the terms "Seller" and "Buyer" are
intended to encompass the Affiliates of each insofar as that is necessary to
give full effect to the rights and obligations of the parties hereunder and to
prevent results which are anomalous in the context of the transactions
contemplated hereby. The covenant or agreement of a party to do or not to do a
thing is also such party's covenant or agreement to cause its relevant
Affiliates to do or not to do that thing. A covenant, agreement, representation
or warranty for the benefit of a party is also for the benefit of such party's
relevant Affiliates. The act, omission or knowledge of a party's relevant
Affiliate is attributed to the party. Damages suffered by a relevant Affiliate
of a party are also suffered by the party.

     8.   DISPUTE RESOLUTION
          ------------------

          8.1  OBJECTIVE. This Agreement will be implemented by the parties and
               ---------
their Affiliates in more than one jurisdiction. The negotiations of the parties
have focused primarily on the ordinary meaning of the provisions of this
Agreement and not on the legal effects those provisions might have under the
laws of a particular jurisdiction. One of the purposes of this Section is to
minimize the possibility of an unexpected reordering of agreed rights and
obligations.

          8.2  NO AFFILIATE ACTIONS. Neither party shall permit any of its
               --------------------
Affiliates to initiate or participate in any legal proceeding in connection with
any controversy or claim arising out of or relating to this Agreement or the
transactions contemplated hereby; rather, Buyer and Seller shall settle all such
controversies or claims on behalf of their Affiliates by arbitration conducted
by the parties in accordance with this Section. Buyer and Seller shall cause
their Affiliates to comply with any award rendered in an arbitration proceeding
pursuant hereto.

          8.3  ARBITRATION. Any controversy or claim arising out of or relating
               -----------
to this Agreement or the transactions contemplated hereby shall be determined by
arbitration in accordance with the Rules of Arbitration of the London Court of
Arbitration, and judgment upon the award rendered by the arbitral tribunal may
be entered in any court having jurisdiction thereof. The place of arbitration
shall be London, England, and the language of the arbitration shall be English.
The arbitral tribunal shall apply the substantive laws of the State of Georgia
without regard to the conflicts of laws principles of the State of Georgia.

          8.4  GOVERNING LAW. This Agreement shall be governed by and
               -------------
interpreted in accordance with the laws of the State of Georgia.

                                       2

     9.   Conflict. If there is any conflict between the terms of this Agreement
          -------- 
and the Purchase Agreement, the terms of the Purchase Agreement shall prevail.
Nothing contained in this Agreement shall be deemed to amend any provision of
the Purchase Agreement.

     IN WITNESS WHEREOF, Buyer and Seller have each caused this Agreement to be
duly executed in its corporate name by a duly authorized representative as of
the date first above written.

a consequence of any change in law, regulation or published revenue authority
practice or policy or the withdrawal of any concession occurring after Closing
with or without retrospective effect; and/or

          4.2.4  the liability arises in consequence of a voluntary act or

other thing after Closing, the making

                                       6

giving or doing of which was taken into account or assumed in computing the
provision for Tax (including the provision for deferred tax) in the Accounts;
and/or

          4.2.11  the liability would not have arisen or is increased because
notice in writing of any Assessment which does or may give rise to a liability

practicable, the event matter or default which gives rise to the Assessment and,
if known to the Buyer, the amount of the liability) is not given to the Seller
in accordance with clause 6.1 of this Deed; and/or
                   ----------

Relief arising after Closing or a Relief which is taken into account as an asset
in the Accounts, which is or can be offset against the liability in question
(and so that the Group Member shall take all necessary steps to claim the
benefit of any such Relief); and/or

          4.2.14  the liability is in respect of any Tax which has been paid or
discharged prior to Closing at no cost to the Buyer;

the Buyer's residence for Tax purposes outside the United Kingdom; and/or

6    Claims Procedure.
     ----------------

     6.1  The Buyer will as soon as reasonably practicable give notice of any
Claim to the Seller, provided that the giving of such notice will not be a
condition precedent to the liability of the Seller under clause 2.
                                                         --------

     6.2  Provided that the Seller indemnifies and secures the Company to the
reasonable satisfaction of the Buyer against all reasonable costs and expenses
(including interest on overdue Taxation) which may be incurred thereby, the

such action and gives such information and assistance in connection with its
Taxation affairs as the Seller may reasonably request to dispute, appeal
against, settle or compromise any Claim, including, but not limited to,:-

          6.2.1  applying to postpone (so far as legally possible) the payment

          6.4.1  the Buyer will not be obliged to prevent the Company from
making a payment of Taxation at the time necessary to avoid incurring any fine,

Taxation; and

giving written notice requiring it to do so to inform the Buyer of any action
which it wishes the Buyer to procure any of the Companies to take under clause
                                                                        ------

     -------

          7.1.2  the amount paid by the Seller under clause 2 in respect of the
                                                     --------
Liability to Taxation which gave rise to the Saving less any part of that amount
previously repaid to the Seller under any provision of this Deed.

     7.2  In determining whether any of the Companies have obtained a Saving,
the Auditors will act as experts and not as arbitrators and their determination
will (in the absence of manifest error) be conclusive and binding on the
parties.

8    OVER PROVISIONS AND UNDERSTATEMENT.
     ----------------------------------     

     8.1  The amount of the Sellers' liability under this Deed shall be reduced
by: (i) the amount (if any) by which any provision for any Liability to Taxation
in the Accounts is confirmed by the relevant Group Member's auditors at the
request of any party to be an over provision; and/or (ii) the amount (if any) by
which the value attributed in the Accounts to any Relief which is treated as an
asset therein is confirmed by the relevant Company's auditors at the request of
any party shall be understated, and to the extent that any such over provision
or under-statement shall be so taken into account in computing the Seller's
liability under this Deed, it shall not thereafter be regarded as an over
provision or understatement in the Accounts.

     8.2  If the Seller shall have paid any amount under this Deed and
subsequently: (i) the amount (if any) by which any provision for any Liability
to Taxation in the Accounts is confirmed by the relevant Company's auditors at

any) by which the value attributed in the Accounts to any Relief which is
treated as an asset therein is confirmed by the relevant Company's auditors at

                                       9
<PAGE>
 
the request of any party shall be understated, the Buyer shall or shall procure
that the relevant Company shall repay to the Seller an amount equal to the
lesser of such payment and the amount of the over provision or the under-
statement (as the case may be) and the amount of any relevant over provision or
under-statement shall thereafter for the purposes of this clause 9 be treated as
                                                          --------
reduced (or, in the case of an understatement, increased) by the amount of such
repayment hereunder.

     8.3  If the Buyer shall discover that there has been such an over provision
or under-statement it shall as soon as reasonably practicable give to the Seller
such details of it of which the Buyer shall be aware, together with such
relevant information as the Seller shall (at the Seller's expense) reasonably
request for the purposes of determining the extent of such over provision or
under-statement.

9    BUYER'S COVENANT.
     ---------------- 

     The Buyer covenants to pay to the Seller:

     9.1  any Liability to Taxation of a Company in respect of which the Seller
is liable to make a payment to the Buyer pursuant to this Deed and where the
assessment under section 767A ICTA would not have been made but for the failure
by a Group Member to discharge that liability to Taxation; and

     9.2  where the Seller has made a payment in respect of Taxation to the
Buyer under this Deed and a Company fails to discharge such Taxation, an amount
equal to any Liability to Taxation which subsequently becomes payable by the
Seller under section 767A ICTA in respect of the same subject matter.

10   RECOVERY FROM OTHER PERSONS.
     ---------------------------

          10.1    If the Company recovers from any other person (including any
Taxation Authority) any amount which is referable to a Liability to Taxation or
other liability of any of the Companies in respect of which the Seller has made
a payment under clause 2, the Buyer will repay to the Seller the lesser of:
                --------

          10.1.1  the amount so recovered (less any reasonable costs and
expenses incurred by the Company); and

          10.1.2  the amount paid by the Buyer under clause 2 in respect of the
                                                     -------- 
Liability to Taxation or other liability in question less any part of such
amount previously repaid to the Buyer under any provision of this Deed.

     10.2 Upon the Buyer becoming aware that the Companies are entitled to
recover any amount mentioned in clause 9.1, the Buyer will promptly give notice
                                ---------- 
of that fact to the Seller and provided that the Seller indemnifies and secures
the Company to the reasonable satisfaction of the Buyer against all reasonable
costs and expenses which may be incurred thereby, the Buyer will procure that
the Company, at the Seller's cost and expense, takes such action as the Seller
may reasonably and promptly request to effect such recovery.

                                      10
<PAGE>
 
11   WITHHOLDINGS. All sums payable by the Seller under this Deed shall be paid
     ------------     
free and clear of all deductions or withholdings unless the deduction or
withholding is required by law, in which event the Seller shall pay such
additional amount as shall be required to ensure that the net amount received by
the Buyer under this Deed will equal the full amount which would have been
received by it had no such deduction or withholding been required to be made
provided that if the Buyer subsequently obtains a credit, repayment or other
form of relief for Taxation in respect of the amount withheld or deducted it
shall, as soon as reasonably practicable after it obtains the benefit of the
credit, repayment or other form of relief account to the Seller for the lesser
of: (a) the amount of the benefit of the credit, repayment or other form of
relief less the reasonable costs and expenses incurred in obtaining such credit,
repayment or other benefit; and (b) the amount of the withholding or deduction.

12   TAX ON INDEMNITY PAYMENTS. If any Taxation Authority brings into charge to
     -------------------------
tax any sum paid to the Buyer (other than a payment to the Buyer in its capacity
as trustee for its successors in title or interest payable under Clause 5.2)
under this Deed (including in circumstances when any Relief is available in
respect of such charge to tax) then the Seller shall pay such additional amount
as shall be required to ensure that the total amount paid, less the tax
chargeable on such amount (or that would be so chargeable but for such Relief),
is equal to the amount which would otherwise be payable under this Deed.

13   GENERAL. All payments by the Seller under this Deed will be treated as
     ------- 
repayments by the Seller of the consideration paid pursuant to the Agreement.

14   GOVERNING LAW. This Deed shall be governed by and interpreted in accordance
     -------------
with the law of Georgia.

Subsidiaries that arose in connection with any failure (or alleged failure) to
pay any Tax.

Governmental Authority to assess any additional Taxes for any period for which

liability of the Company or any of its Subsidiaries either (i) claimed or raised
by any Governmental Authority in writing or (ii) as to which the Company has
knowledge based upon personal contact with any agent of such authority.

(S) 280G.  Neither the Company nor any of its Subsidiaries has been a United
States real property holding corporation within the meaning of Code (S)
897(c)(2) during the applicable period specified in Code (S) 897(c)(1)(A)(ii).

                                       23
<PAGE>
 
its federal income Tax Returns all positions taken therein that could give rise
to a substantial understatement of federal income Tax within the meaning of Code
(S) 6621. Neither the Company nor any of its Subsidiaries is a party to any Tax
allocation or sharing agreement. Neither the Company nor any of its Subsidiaries
has been a member of an Affiliated Group filing a consolidated federal income
Tax Return other than a group consisting of the Company and its Subsidiaries.

          (f) Schedule 5.11 sets forth the following information with respect to

each of the Company and its Subsidiaries (or, in the case of clause (ii) below,
with respect to each of the Subsidiaries) as of the most recent practicable date
(as well as on an estimated pro forma basis as of the Closing giving effect to
the consummation of the transactions contemplated hereby and by the other
Transaction Documents and the Acquisition Documents); (i) the basis of the
Company or Subsidiary in its assets, (ii) the basis of the stockholder(s) of the
Subsidiary in its stock (or the amount of any excess loss account); (iii) the
amount of any net operating loss, net capital loss, unused investment or other
credit, unused foreign tax, or excess charitable contribution allocable to the
Company or Subsidiary; and (iv) the amount of any deferred gain or loss
allocable to the Company or Subsidiary arising out of any deferred intercompany
transaction.

          (g) The unpaid Taxes of the Company and its Subsidiaries (i) did not,
as of April 30, 1998 month end, exceed the reserve for Tax liability (rather
than any reserve for deferred Taxes established to reflect timing differences
between book and Tax income) set forth on the face of the balance sheet for such
month end (rather than in any notes thereto) and (ii) do not exceed that reserve
as adjusted for the passage of time through the Closing Date in accordance with
the past custom and practice of the Company and its Subsidiaries in filing their
Tax Returns.

          (h) Neither the Company nor any of its Subsidiaries has any liability
for the Taxes of any person or entity other than the Company and its
Subsidiaries (i) under Reg. (S) 1.1502-6 (or any similar provision of state,
local or foreign law), (ii) as a transferee or successor, (iii) by contract, or
(iv) otherwise.

          (i) Each Affiliated Group has filed all income Tax Returns that it was
required to file for each taxable period during which any of the Company and its
Subsidiaries was a member of the group.  All such Tax Returns were correct and
complete (i) in all respects insofar as they relate to any of the Company and
its Subsidiaries and (ii) in all material respects insofar as they do not relate
to the Company and its Subsidiaries.  All material income Taxes owed by any
Affiliated Group (whether or not shown on any Tax Return) have been paid for
each taxable period during which any of the Company and its Subsidiaries was a
member of the group.

          (j) Neither the Company nor any of its Subsidiaries expects any
Governmental Authority to assess any additional income Tax against any

Subsidiaries was a member of the group.  There is no dispute or claim concerning
any income Tax liability 

                                       24

of any Affiliated Group for any taxable period during which any of the Company
and its Subsidiaries was a member of the group either (i) claimed or raised by
any Governmental Authority in writing or (ii) as to which the Company has
knowledge based upon personal contact with any agent of such authority. Except
as disclosed on Schedule 5.11, no Affiliated Group has waived any statute of
                -------------                         
limitations in respect of any income Taxes or agreed to any extension of time
with respect to an income Tax assessment or deficiency for any taxable period
during which any of the Company and its Subsidiaries was a member of the group.

first day of the year in which the Closing Date occurs other than those
liabilities with respect to such Plans specifically described on Schedule
                                                                 --------

entered into in connection with the transactions contemplated in this Agreement.
There are no outstanding liabilities of the Company or any ERISA Affiliate to
any employee benefit plans previously maintained by the Company or any ERISA
Affiliate, and the Company is not aware of any potential liabilities in
connection therewith.  There are no actions, suits or claims, other than for
benefits in the ordinary course, pending or, to the knowledge of the Company,

state law is pending or threatened against any fiduciary of the Plans.  No Plan,
or any fiduciary thereof, has been, or is currently the direct or indirect
subject of an audit, investigation or examination by any Governmental Authority.
All of the Plans comply currently, and have complied in the past, both as to
form and operation, in all material respects, with their terms and with all

provided for in this Agreement, the Company agrees to indemnify and hold
harmless the Purchaser and its Affiliates and each of their respective officers,

action or proceeding between the Company and such Indemnified Party (or
Indemnified Parties) or between an Indemnified Party (or Indemnified Parties)

value (collectively, "LIABILITIES") resulting from or arising out of any breach
of any representation or warranty, covenant or agreement of the Company in this
Agreement, the Note or the other Transaction Documents, including without
limitation, the failure to make payment when due of amounts owing pursuant to
this Agreement, the Note or the other Transaction Documents, on the due date
thereof (whether at the scheduled maturity, by acceleration or otherwise) or any
legal, administrative or other actions (including, without limitation, actions
brought by the Purchaser, the Company, any of its Subsidiaries or any equity
holders of the Company or any of its Subsidiaries or derivative actions brought
by any Person claiming through or in the Company's or any Subsidiary's name),
proceedings or investigations (whether formal or informal), or written threats
thereof, based upon, relating to or arising out of the Transaction Documents,
the transactions contemplated thereby, or any Indemnified Party's role therein
or in the transactions contemplated thereby; provided, however, that the Company
                                             --------  -------
shall not be liable under this Section 7.1 to an Indemnified Party: (a) for any
amount paid by the Indemnified Party in settlement of claims by the Indemnified
Party without the Company's consent (which consent shall not be unreasonably
withheld), (b) to the extent that it is finally judicially determined that such
Liabilities resulted primarily from the willful misconduct or gross negligence
of such Indemnified Party or (c) to the extent that it is finally judicially
determined that such Liabilities resulted primarily from the breach by such
Indemnified Party of any representation, warranty, covenant or other agreement
of such Indemnified Party contained in this Agreement; provided, further, that
                                                       --------  ------- 
if and to the extent that such indemnification is unenforceable for any reason,

expenses as set forth above, the Company further agrees, upon presentation of
appropriate invoices containing reasonable detail, to reimburse each Indemnified
Party for all such expenses (including, without limitation, reasonable fees,
disbursements and other charges of counsel incurred by an Indemnified Party in
any action or proceeding between the Company and such Indemnified Party (or
Indemnified Parties) or between an Indemnified Party (or Indemnified Parties)
and any third party or otherwise) as they are incurred by such Indemnified
Party; provided, however, that if an Indemnified Party is reimbursed hereunder
       --------  -------
for any expenses, such reimbursement of expenses shall be refunded to the extent
it is finally judicially determined that the Liabilities in question resulted
primarily from (i) the willful misconduct or gross negligence of such
Indemnified Party or (ii) the breach by such Indemnified Party of any
representation, warranty, covenant or other agreement of such Indemnified Party
contained in this Agreement or any other Transaction Document.

     7.2  PROCEDURE; NOTIFICATION.  Each Indemnified Party under this
          -----------------------                                    
Article 7 will, promptly after the receipt of notice of the commencement of any
action, investigation, claim or other proceeding against such Indemnified Party
in respect of which indemnity may be sought from the Company under this Article
7, notify the 

                                       39
<PAGE>
 
Company in writing of the commencement thereof. The omission of any Indemnified
Party so to notify the Company of any such action shall not relieve the Company
from any liability which it may have to such Indemnified Party unless, and only
to the extent that, such omission results in the Company's forfeiture of
substantive rights or defenses. In case any such action, claim or other
proceeding shall be brought against any Indemnified Party, and it shall notify
the Company of the commencement thereof, the Company shall be entitled to assume
the defense thereof at its own expense, with counsel satisfactory to such
Indemnified Party, in its reasonable judgment; provided, however, that any
                                               --------  -------
Indemnified Party may, at its own expense, retain separate counsel to
participate in such defense. Notwithstanding the foregoing, in any action, claim
or proceeding in which the Company, on the one hand, and an Indemnified Party,
on the other hand, is, or is reasonably likely to become, a party, such
Indemnified Party shall have the right to employ separate counsel at the
Company's expense and to control its own defense of such action, claim or
proceeding if, in the reasonable opinion of counsel to such Indemnified Party, a
conflict or potential conflict exists between the Company, on the one hand, and
such Indemnified Party, on the other hand, that would make such separate
representation advisable; provided, however, that in no event shall the Company
                          --------  -------                                    
be required to pay fees and expenses under this Article 7 for more than one firm
of attorneys in any jurisdiction in any one legal action or group of related
legal actions. The Company agrees that it will not, without the prior written
consent of the Purchaser, settle, compromise or consent to the entry of any
judgment in any pending or threatened claim, action or proceeding relating to
the matters contemplated hereby (if any Indemnified Party is a party thereto or
has been actually threatened to be made a party thereto) unless such settlement,
compromise or consent includes an unconditional release of the Purchaser and
each other Indemnified Party from all liability arising or that may arise out of
such claim, action or proceeding.  The Company shall not be liable for any
settlement of any claim, action or proceeding effected against an Indemnified
Party without its written consent, which consent shall not be unreasonably
withheld.  The rights accorded to Indemnified Parties hereunder shall be in
addition to any rights that any Indemnified Party may have at common law, by
separate agreement or otherwise.

preparation, execution and delivery of (i) the Subordinated Note and Common
Stock Purchase Agreement (the "Note Purchase Agreement") by and among Nitinol,
Whitney Subordinated Debt Fund, L.P. (the "Lender"), and, for certain purposes,
J.H. Whitney & Co. ("J.H. Whitney" or "Agent") providing for, among other
things, a $20,000,000 loan from the Lender to the Company and the issuance by
the Company of an aggregate of 675,000 shares of common stock, par value $.001

     (a)  the Note Purchase Agreement;

     (b)  the WSDF Note;

     (c)  the Guarantee and Collateral Agreement;

     (d)  the Dutch Pledge Agreement;

     (e)  the Charge Over Shares;

     (f)  UCC-1 financing statements in the form annexed hereto as Exhibit B
                                                                   ---------
(the "Financing Statements") to be filed in the filing offices listed on
Schedule I;
- ----------

     (g)  The Certificate of Incorporation or similar charter document of each
of the Borrowers, each in effect on the date hereof (collectively, the
"Certificates of Incorporation");

     (h)  the By-laws of each of the Borrowers, each as in effect on the date
hereof, provided to us by the Borrowers (collectively, the "By-Laws");

     (i)  all records contained in the corporate minute books of each of the
Borrowers, as provided to us by the Borrowers, relating to the period commencing
on January 1, 1997 and ending on the date hereof, and the stock record books of
each of the Borrowers (other than the Company), as provided to us by such
Borrowers;

     (j)  the certificates of legal existence and corporate good standing listed
on Exhibit C hereto for the Company and each of the Subsidiaries, issued by the
   ---------
Secretary of State of the State of Delaware and the Secretaries of State of the
other jurisdictions listed thereon;

     (k)  certified copies of resolutions adopted by the Boards of Directors of
each of the Borrowers approving the transactions contemplated by the Note
Purchase Agreement and authorizing, among other things, the execution, delivery

defined below (the "Authorizing Resolutions");

     (l)  authorization, incumbency and signature certificates as to the
officers of each of the Borrowers;
<PAGE>
 
Whitney Subordinated Debt Fund, L.P.

Page 3

     (m)  the certificate of Theodore I. Pincus, Executive Vice President of the
Company and Treasurer of each of the Subsidiaries, in the form attached hereto
as Exhibit D;
   ----------

     (n)  such other documents, instruments and certificates (including, but not
limited to, certificates of public officials and officers of the Borrowers) as
we have considered necessary for purposes of this opinion; and

     (o)  the Acquisition Documents.

The documents listed in clauses (a)-(c) and (f) are referred to collectively
herein as the "Transaction Documents."

     We assume, for purposes of this opinion, that the corporate records
(referred to in clause (i) above) contain an accurate record of all meetings of
the stockholders and directors of each of the Borrowers after January 1, 1997
and that the stock record books of each of the Borrowers are materially complete
and accurate.

     In our examination of the documents described above, we have assumed the
genuineness of all signatures, the authenticity of all documents submitted to us
as originals, the conformity to original documents of all copies of documents
submitted to us, the authenticity of the originals of such latter documents, and
the legal capacity of all individual signatories.

     Insofar as this opinion relates to factual information which is in the
possession of the Borrowers, we have relied, with your consent, exclusively upon
certificates, statements and representations made to us by one or more officers
or employees of the Borrowers and other representatives or agents of the Company
and the representations of the Borrowers contained in the Transaction Documents.
Nothing has come to our attention which causes us to believe that you are not
justified in relying upon such certificates, statements and representations of
officers and other representatives or agents of the Company.

     Any reference to "our knowledge", or to matters "known to us", "coming to
our attention", or "of which we are aware", or any variation of any of the
foregoing shall mean the conscious awareness of the attorneys in this firm who
have rendered substantive attention to this transaction of the existence or
absence of any facts which would contradict our opinions set forth below. We
have not undertaken any independent investigation to determine the existence or
absence of such facts, and no inference as to our knowledge of the existence or
absence of such facts should be drawn from the fact of our representation of the
Borrowers. Without limiting the foregoing, we have not conducted a search of any
computerized or electronic databases or the dockets of any court or
administrative or other regulatory agency in any jurisdiction.

     We have assumed that all parties to the Transaction Documents other than
the Borrowers have the power and authority and have taken the corporate or
partnership action necessary to execute and deliver the Transaction Documents
and all other instruments to which they are a party in connection therewith, and
that except for the filing of Financing Statements, no consent, approval,
authorization, declaration or filing by or with any governmental commission,
board or agency is required for each of such parties' valid execution and
delivery of such documents. We have assumed each of such parties' due execution
and delivery of the Transaction Documents to which they are a party, and that
such Transaction Documents constitute such parties' valid and binding
obligations, enforceable against them in accordance with their respective terms.
We are expressing no opinion herein as to the application of or compliance with
any federal or state law or regulation to the power, authority or competence of
any party to the documents as to which we are opining herein, other than the
Borrowers.

     We express no opinion herein with respect to the laws of any state or
jurisdiction other than the federal laws of the United States of America, the
state laws of the Commonwealth of Massachusetts and the General Corporation Law
statute of the State of Delaware. To the extent that the laws of any other
jurisdiction govern any of the matters as to which we are opining herein, we
have assumed that such laws are identical to the state laws of the Commonwealth
of Massachusetts, and we are expressing no opinion herein as to whether such
assumption is reasonable or correct. We note that the Transaction Documents are
governed by the laws of the State of New York. We further note that Cordis
Innovasive Systems, Inc. ("CIS") is a Florida corporation and, for purposes of
our opinions expressed in paragraphs 2 and 3 below as to no conflict with the
charter and by-laws of CIS and the due execution and delivery of the Guarantee
and Collateral Agreement, respectively, we have assumed that Massachusetts law
governs CIS. We express no opinion herein with respect to compliance with the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

     The opinions expressed in paragraph l below, insofar as they relate to the
due organization, valid existence and corporate good standing of the Company and
each of the Subsidiaries, and the foreign qualification of certain of the
Subsidiaries are based solely upon the certificates listed on Exhibit C and are
                                                              ---------
rendered as of the dates of such certificates and limited accordingly.

     With respect to our opinions expressed in paragraphs 2, 4 and 9 below, the
Contractual Obligations "known to us" include only those documents to which the
Company and/or the Subsidiaries is a party and which are filed as exhibits to
reports filed by the Company with the Securities and Exchange Commission
pursuant to the reporting requirements of the Securities Exchange Act of 1934,
as amended (the "Exchange Act documents"). The opinion expressed in paragraph 4
as to the Company's issued and outstanding stock is based solely on a
certificate dated as of
<PAGE>
 
Whitney Subordinated Debt Fund, L.P.
July 8, 1998
Page 5

July 2, 1998 of American Stock Transfer and Trust Co., the Company's transfer
agent. The opinions expressed in the third sentence of paragraph 4 and as to the
fully paid and nonassessable nature of the outstanding shares of the Company's
and the Subsidiaries' capital stock are based solely on the Officer's
Certificate attached hereto as Exhibit D.
                               ---------
     
     Our opinions below are qualified to the extent that they may be subject to
or affected by (i) applicable bankruptcy, insolvency, reorganization,
moratorium, fraudulent conveyance, usury, or similar laws affecting the rights
of creditors generally, (ii) statutory or decisional law concerning recourse by
creditors to security in the absence of notice or hearing, and (iii) duties and
standards imposed on creditors and parties to contracts, including, without
limitation, requirements of good faith, reasonableness and fair dealing.
Notwithstanding the foregoing, our opinions set forth below are not qualified as
to the application of Massachusetts General Laws Chapter 271, Section 49(a)-(c),
based solely on our understanding that J.H. Whitney & Co., Inc., as agent, has
complied with the notification requirement set forth in (S)49(d) of Chapter 271,
and assuming for this purpose that the laws of the Commonwealth of Massachusetts
govern the Transaction Documents. Furthermore, we express no opinion as to the
availability of any equitable or specific remedy upon any breach of the
documents as to which we are opining here or any of the agreements, documents or
obligations referred to therein, or as to the successful assertion of any
equitable defense, as the availability of such remedies or defenses may be
subject to the discretion of a court. We express no opinion as to the
enforceability of a waiver of rights granted by the Constitution of the United
States of America, or any state thereof, or the vesting of jurisdiction in, or
the consent to the exercise of jurisdiction by, any court where the exercise of
such jurisdiction is within the discretion of such court, or the court is not a
court of general jurisdiction.

     We are expressing no opinion as to compliance by the Borrowers with the so-
called "blue sky" or state securities laws (other than the securities laws of
the Commonwealth of Massachusetts), or with state or federal antifraud laws, in
connection with the issuance and sale of the WSDF Note or the Shares.

     We express no opinion as to the enforceability of any right of set-off
against any deposit account of a Borrower to the extent that (i) the funds on
deposit in said accounts have been accepted by you with an intent to apply such
funds to a preexisting claim rather than to hold such funds subject to
withdrawals in the ordinary course, (ii) the set-off is directed against checks
held by you for collection only and not for deposit, (iii) the funds on deposit
in said accounts are in any manner special accounts which, by the express terms
on which they are created are made subject to the rights of a third party, or
(iv) the obligations against which any deposit account is set-off are not due
and payable.

     Based upon and subject to the foregoing, and further subject to the
qualifications set forth below, it is our opinion that:

     1.   The Company and each of its Subsidiaries: (i) is, and after giving
effect to the transactions contemplated by the Transaction Documents and the
Acquisition Documents, will be a corporation duly organized, validly existing
and in good standing under the laws of the jurisdiction of its incorporation;
(ii) has, and after giving effect to the transactions contemplated by the
Transaction Documents and the Acquisition Documents, will have all requisite
corporate power and authority to own and operate its property (as such property
is known to us), to lease the property it operates as lessee (as such property
is known to us) and to conduct the business in which it is, to our knowledge,
currently engaged; and (iii) has the corporate power and authority to execute,
deliver and perform its obligations under each Transaction Document to which it
is or will be a party. The Company and NMT Heart Inc. are duly qualified to do
business and in good standing in the Commonwealth of Massachusetts.

     2.   The execution, delivery and performance by the Company and each of the
Subsidiaries of each Transaction Document and Acquisition Document to which it
is a party and the consummation of the transactions contemplated hereby and
thereby, including without limitation the issuance of the WSDF Note and the
Shares: (i) has been duly authorized by all necessary corporate action; (ii)

     3.   Each Transaction Document and Acquisition Document to which the

of Common Stock reserved for issuance pursuant to the exercise of stock options
not issued pursuant to a plan (collectively, the "Options"); (iv) 83,329 shares

(together with the warrants described above in (iv), (v) and (vi), the
"Warrants"); and (viii) 84,973 shares of Common Stock reserved for issuance in
connection with the Company's 1997 Employee Stock Purchase Plan. All outstanding
shares of capital stock of the Company issued after January 1, 1997 have been
duly authorized by all necessary corporate action and are validly issued, fully
paid and nonassessable. To our knowledge, the shareholders of the Company have
no preemptive or similar rights with respect to the issuance or sale of the
Shares under any Contractual Obligation known to us.

     5.   To our knowledge, except for the Warrants and the Options and as set
forth on Schedule 5.19(b) to the Note Purchase Agreement, there are, and after
giving effect to the transactions contemplated by the Transaction Documents and
the Acquisition Documents, there will be, no outstanding securities convertible
into or exchangeable for capital stock of the Company or options, warrants or
other rights to purchase or subscribe to capital stock of the Company or
contracts, commitments, agreement, understandings or arrangements of any kind to
which the Company is a party relating to the issuance of any capital stock of
the Company, any such convertible or exchangeable securities or any such
options, warrants or rights.

     6.   To our knowledge, except as disclosed in the Transaction Documents,
there are no actions, suits, proceedings, claims or disputes pending or
threatened, at law, in equity, in arbitration or before any federal or state
court or governmental authority or agency against the Company or any Subsidiary.
To our knowledge, no injunction, writ, temporary restraining order, decree or
any order of any nature specifically naming the Company or the Subsidiaries has
been issued by any court or other governmental authority purporting to enjoin or
restrain the execution, delivery and performance of any of the Transaction
Documents.

     7.   Assuming the accuracy of the representations and warranties contained
in the Note Purchase Agreement, the offer, sale and issuance of the Shares and
the WSDF Note are exempt from the registration requirements under the Securities
Act of 1933, as amended and applicable Massachusetts securities laws.

     8.   After giving effect to the transactions contemplated by the
Acquisition Documents, neither the Company nor any Subsidiary is an "investment
company" within the meaning of the Investment Company Act of 1940, as amended.

     9.   To our knowledge, except as provided in the Transaction Documents or
disclosed on the Schedules to the Note Purchase Agreement, none of the
Contractual Obligations of the Company known to us (i) restricts the voting or
transfer or requires the registration of any capital stock of the Company, (ii)
requires the Company to repurchase or otherwise acquire, retire or sell any
capital stock of the Company or (iii) restricts the payments of dividends on any
shares of capital stock of the Company.

     10.  Each of the Note Purchase Agreement, the WSDF Note, the Guarantee and
Collateral Agreement and the Acquisition Documents constitutes the valid and
binding obligation of the Company and the Subsidiaries party thereto,
enforceable against the Company and the Subsidiaries party thereto in accordance
with its terms.

     11.  The stock certificates representing the Shares are in proper form 
under all applicable provisions of Delaware law.

     12.  Except for filings which are necessary to perfect the security
interests granted under the Transaction Documents, for filings under United
States state and federal securities laws, and any other filings, authorizations
or approvals as are specifically provided for in the Transaction Documents, no
authorizations or approvals of, and no filings with, any governmental or
regulatory authority or agency are necessary under any relevant law for the
execution, delivery or performance by the Company or any of the Subsidiaries of
the Transaction Documents to which it is a party.

     13.  If the Guarantee and Collateral Agreement were governed by the laws of
the Commonwealth of Massachusetts, then after giving effect to the purchase of
the WSDF Note on the Closing Date, the Guarantee and Collateral Agreement would
create a valid security interest under the Uniform Commercial Code as enacted in
the Commonwealth of Massachusetts (the "Code") in favor of the Agent, for the
benefit of the Lender and the Agent, to secure the Obligations (as defined in
the Guarantee and Collateral Agreement), in all right, title and interest of the
Company and the Grantors (the "Debtors") in and to the Collateral (as defined in
the Guarantee and Collateral Agreement exclusive of the Pledged Securities) in
which a security interest can be created under the Code. The Agent's security
interest in the Collateral will be perfected under Article 9 of the Code upon
due filing of the financing statements in the form attached as Exhibit B in the
                                                               ---------
offices listed on Schedule I with respect to filings made in filing offices in
                  ----------
the Commonwealth of Massachusetts, or under the Uniform Commercial Code enacted
in the jurisdictions in which such other filing offices are located.

     14.    If the Guarantee and Collateral Agreement were governed by the laws
of the Commonwealth of Massachusetts, then after giving effect to the purchase
of the WSDF Note on the Closing Date and assuming that (i) the Agent has, at the
date of this letter, possession of the certificates representing the Pledged
U.S. Shares of the Grantors, together with related stock powers which have been
duly executed in blank by the Borrower and certain of the Grantors, as the case
may be, and maintains continuous possession of the Pledged U.S. Shares and stock
powers, and (ii) on the date hereof the Lender and the Agent do not have notice
of any adverse claim to the Pledged U.S. Shares, then the Agent has a valid and
perfected security interest, for the benefit of the Lender and the Agent, to
secure the Obligations (as defined in the Guarantee and Collateral Agreement),
in all right, title and interest of the Company and the Grantors in and to the
Pledged U.S. Shares, which security interest has priority over any other
security interest in the Pledged U.S. Shares which can be perfected under the
Code.

     The foregoing opinions are subject to the following comments and
qualifications:

     i.     The enforcement against the Borrowers of any rights and remedies is
or may be subject to the effect of certain general principles of contract law
that include (a) the unenforceability of provisions of an agreement to the
effect that provisions therein may only be amended or waived in writing to the
extent that an oral agreement modifying such provisions has been entered into;
and (b) the general rule that, where less than all of an agreement is
enforceable, the balance is enforceable only when the unenforceable provision is
not an essential part of the agreed exchange.

     ii.    We express no opinion in paragraph 13 as to the creation of security
interests in property in which a security interest cannot be created under the
Code or the perfection of security interests in property in which a security
interest cannot be perfected by the filing of UCC-1 Financing Statements
pursuant to Article 9 of the Code in the filing offices described in Schedule I
                                                                     ----------
hereto. We express no opinion as to the perfection of security interests in
fixtures.

     iii.   We express no opinion as to the priority of any security interests
granted by the Borrowers to or for the benefit of the Lender except with respect
to Pledged U.S. Shares. We express no opinion as to the existence of, or the
right, title or interest of the Borrowers in, to or under any property in which
it has granted a security interest.

     iv.    The perfection of the security interests may be terminated as to any
Collateral of a Borrower acquired by such Borrower more than four months after
such Borrower changes its name, identity or corporate structure so as to make
the Financing Statements seriously misleading (within the meaning of Section 9-
402(7) of
<PAGE>
 
Whitney Subordinated Debt Fund, L.P.
July 8, 1998
Page 10

the Code) unless new, appropriate financing statements indicating the new name,
identity or corporate structure of such Borrower are properly filed before the
expiration of such four-month period and all fees in connection therewith are
paid. The perfection of security interests in accounts, including receivables,
general intangibles and certain other Collateral of a Borrower may be terminated
if such Borrower changes the location of its chief executive offices.

     v.     Pursuant to the Code, continuation statements are required from time
to time to be filed in order to preserve valid, perfected security interests.

     vi.    We have assumed that the Collateral of the Borrowers is located at
the locations described on Schedule II hereto and that the chief executive
                           -----------
offices of the Borrowers are located as described on Schedule II.
                                                     -----------

     vii.   We express no opinion as to the adequacy of the description of the
Collateral of the Borrowers as defined in the Note Purchase Agreement insofar as
such description includes terms which are not defined under Article 9 of the
Code.

     viii.  We express no opinion as to the legal capacity of natural persons.

     ix.    Under certain circumstances, described in Section 9-306 of the Code,
the right of a secured party to enforce a perfected security interest in the
proceeds of collateral may be limited.

     x.     The grant of, or any realization on, security interests in
governmental licenses, permits, authorizations and other rights, in contracts
with government or governmental instrumentalities, commissions, boards or
agencies and in the proceeds thereof are or may be subject to restrictions or
limitations set forth therein or in applicable statutes, laws, rules or
regulations, and we express no opinion as to the creation or perfection of
security interests in such rights, contracts or proceeds (to the extent affected
by such restrictions or limitations).

     xi.    We express no opinion as to the enforceability of prospective
waivers of rights to notice, or to a hearing or other right granted by
constitution or statute, provisions purporting to relieve parties of the
consequences of their own negligence or misconduct, choice of law provisions, or
provisions purporting to establish evidentiary standards.

     This opinion is based upon currently existing statutes, rules, regulations
and judicial decisions, and we disclaim any obligation to advise you of any
change in any of these sources of law or subsequent legal or factual
developments which might affect any matters or opinions set forth herein.

Our ref: PJS/9687-l/tsc                                              8 JULY 1998

Dear Ladies and Gentlemen:

We have acted as English legal advisers to NMT Neurosciences (International),
Inc ("NMT International"), a Delaware corporation and its wholly owned
subsidiary, NMT Neurosciences (UK) Limited, a company incorporated in England
("NMT UK") in connection with the preparation, execution and delivery of a Deed
of Charge over shares in NMT UK ("the Deed of Charge") between NMT 1nternational
and J.H. Whitney & Co., Inc ("Whitney").

In rendering the opinions expressed below, we have examined:-

(a)  the Deed of Charge;

(b)  the Certificate of Incorporation of NMT UK;

(c)  the Memorandum and Articles of Association of NMT UK certified to be in
     effect by a director of NMT UK on 7th July 1998;

(d)  the corporate minute books of NMT UK as provided to us by NMT International
     from the date of its incorporation to the date hereof;

(e)  such other documents as we have considered necessary for purposes of this
     opinion.

We assume, for purposes of this opinion, that the corporate minute books
(referred to in clause (d) above) contain an accurate record of all meetings of
the shareholders and directors of NMT UK.

In our examination of the documents described above, we have assumed the
genuineness of all signatures, the capacity, power and authority of all parties
to execute and deliver the Deed of Charge and all other applicable documents,
the authenticity of all documents submitted to us as originals, the conformity
to original documents of all copies of documents submitted to us as certified or
photostatic copies, the authenticity of the originals of such latter documents,
the due execution and delivery of the Deed of Charge by NMT International and
Whitney, that the Memorandum and Articles of Association of NMT UK were true
complete and up-to-date as at the

J H WHITNEY & CO., INC.                                              8 JULY 1998

date of this opinion and that the resolutions in the minute books referred to in
clause (d) have not been amended or rescinded and are in full force and effect.

We have assumed that there are no provisions of the laws of any relevant
jurisdiction outside England which would be contravened by the execution,
delivery or performance of the Deed of Charge and that, insofar as any
obligation under the Deed of Charge fails to be performed in any jurisdiction
outside England, its performance will not be illegal or adversely affected by
virtue of the laws or regulations of or applicable in that jurisdiction.

We express no opinion herein with respects to the laws of any state or
jurisdiction other than that of England.

Our opinions below are qualified to the extent that the validity or
enforceability of the documents referred to or of any of the rights granted to
any party pursuant thereto may be subject to or affected by (i) applicable
bankruptcy, insolvency, reorganisation, moratorium, fraudulent conveyance, or
similar laws affecting the rights of creditors generally and (ii) duties and
standards imposed on creditors and parties to contracts, including, without
limitation, requirements of good faith, reasonableness and fair dealing.
Furthermore, we express no opinion as to the availability of any equitable or
specific remedy upon any breach of such documents or any of the agreements,
documents or obligations referred to therein, as the availability of such
remedies may be subject to the discretion of a court.

Based upon and subject to the foregoing, and further subject to the
qualifications set forth below, it is our opinion that:-

(a)  NMT UK is a company duly incorporated in England;

(b)  The register of members in the corporate minute books of NMT UK records
     that NMT International is the holder of the entire issued share capital of
     NMT UK consisting of 100 fully paid ordinary shares of (Pounds)1 each, all
     of which have been duly issued to NMT International;

(c)  To the best of our knowledge, there are no actions, suits, proceedings,
     claims or disputes pending or threatened, at law, in equity, in arbitration
     or before any court or governmental authority or agency in the UK against
     NMT International or NMT UK with respect to the Deed of Charge or the
     transactions contemplated thereby. To the best of our knowledge, no
     injunction, writ, temporary restraining order, decree or any order of any
     nature has been issued by any court or other governmental authority in the
     UK purporting to enjoin or restrain the execution, delivery and performance
     of the Deed of Charge;

(d)  The execution, delivery and performance by NMT International of the Deed of
     Charge and the transactions contemplated thereby does not contravene the
     terms of NMT's Articles of Association and will not violate, conflict with
     or result in any breach or contravention of any requirement of English law;

(e)  The Deed of Charge creates an equitable fixed charge over the shares in NMT
     UK expressed to be charged thereby;

J H WHITNEY & CO., INC.                                              8 JULY 1998

(f)  The Deed of Charge creates a valid and binding obligation of NMT
     International, enforceable in accordance with its terms;

(g)  Except for filings which are necessary to perfect the security interests
     granted under the Deed of Charge and any other filings, authorisations or
     approvals as are specifically provided for in the Deed of Charge, no
     authorisations or approvals of, and no filings with, any governmental or
     regulatory authority or agency in England are necessary under English law
     for the execution, delivery or performance by NMT International of the Deed
     of Charge.

The foregoing opinions are subject to the following comments and qualifications:

(i)    An English court may not give effect to a purported obligation to pay
       another party's litigation costs and may make its own order as to costs;

(ii)   While English courts have power to give judgment expressed as an order to
       pay a currency other than pounds sterling, they may decline to do so in
       their discretion and may not enforce the benefit of currency conversion
       and indemnity clauses;

(iii)  Claims may become barred under the Limitations Act or may be or become
       subject to defences of set-off or counterclaim;

(iv)   The enforcement of the rights and obligations of the parties to the Deed
       of Charge may be limited by the provisions of English law concerning
       frustration of contracts;

(v)    It is beyond the scope of this opinion to deal comprehensively with
       matters concerning property, assets and rights expressed to be subject to
       the Deed of Charge and the priority, nature, registration and enforcement
       of the Deed of Charge and its effectiveness in all circumstances. In
       particular we express no opinion in this letter as to the following
       matters:

       (a) the marketability or value of any of the shares in NMT UK expressed
           to be subject to the Deed of Charge;

       (b) the priority of any security or whether any of the shares in NMT UK
           are or may become subject to any equities, rights or interests in
           favour of any other person in priority to the Deed of Charge or
           otherwise;

(vi)   The enforcement of security interests is subject to certain rules of law;
       for example a person who holds a charge over property cannot sell the
       property to himself and owes a duty to take reasonable care to realise
       the property for a proper price;

(vii)  Clause 9 of the Deed of Charge (Severability) may not be effective under
       English law;

(viii) Although Clause 10.2 of the Deed of Charge (Waiver) contemplates written
       waivers, an agreement may be varied, amended or discharged by a further
       agreement or collateral agreement which may he effected by an oral
       agreement or a course of dealing;

J H WHITNEY & CO., INC.                                              8 JULY 1998

(ix)  Notwithstanding Clause l of Schedule 3 of the Deed of Charge, as between
      NMT International and NMT UK English law entitles NMT International to
      receive dividends from NMT UK and to exercise the voting and other rights
      in respect of the shares of NMT UK which are subject to the Deed of Charge
      while they are registered in the name of NMT International rather than
      that of Whitney, whether or not any events of default have occurred. Thus
      in theory NMT International could in future procure the issue of further
      shares by NMT UK, so diluting the shares which are subject to the Deed of
      Charge. Further NMT International could in theory transfer the charged
      shares to a third party while they are registered in the name of NMT
      International (if NMT International could induce the directors of NMT UK
      to issue a duplicate share certificate). To perfect its security Whitney
      need to be registered as the holder of the shares. If it is not so
      registered, it could protect itself to some extent by serving a stop
      notice on NMT UK;

(x)   Although the Articles of Association of NMT UK do not give the Directors
      of NMT UK the right to refuse registration of any transfer of shares which
      are fully paid, they do give the Directors the right to refuse
      registration in the case of shares on which NMT UK has a lien. The
      Articles of Association could also in theory be amended in the future to
      make registration more difficult for Whitney. To perfect its security
      Whitney need to be registered as the holder of the shares.

This opinion is based upon currently existing statutes, rules, regulations and
judicial decisions, and we disclaim any obligation to advise you of any change
in any of these sources of law or subsequent legal or factual developments which
might affect any matters or opinions set forth herein.

Please note that we are opining only as to the matters expressly set forth
herein, and no opinion should be inferred as to any other matters. This opinion
is solely for your benefit, and the benefit of your Counsel, in connection with
the consummation of the transactions contemplated by the Deed of Charge, and may
not be quoted or relied upon by any other person or used for any other purpose,
without our prior written consent.

Very truly yours,

Ladies and Gentlemen:


This opinion is rendered to you at your request with respect to certain matters
of Netherlands Law relating to Yellow Tape B.V. ("Yellow Tape") and Nitinol
                                                  -----------

deed of pledge dated July 9, 1998 among (i) NMT Neurosciences (International),
Inc., a Delaware corporation ("NMT") as pledgor of certain shares in Yellow

As to matters of fact I have relied upon the documents I have examined and upon 
statements or certificates of directors or representatives of Yellow Tape, 
Nitinol, NMT or the Borrower and of public officials.

The following opinion is limited in all respects to the laws of (i) the 
Netherlands with general applicability and (ii) the European Union insofar as 
they are directly applicable in the Netherlands, as they stand at the date 
hereof and as they are presently interpreted under published case law of the 
courts of the Netherlands ("Netherlands Law"). I do not express any opinion on 
                            ---------------    
tax law, on public international law or on the rules promulgated under or by any
treaty or treaty organization. 

In this opinion letter Netherlands legal concepts are expressed in English terms
and not always in their original Netherlands terms. The concepts concerned may 
not be identical to the concepts described by the same English terms as they 
exist under the laws of other jurisdictions.

In rendering this opinion, I have assumed that:

(a)  all original documents are authentic and the signatures thereon are genuine
     and all documents submitted to me as final drafts of documents or as
     photocopy or facsimile copy are in conformity with the executed originals;

(b)  the Yellow Tape Deed of Incorporation has been signed by a civil law
     notary (notaris) and the contents of the Yellow Tape Deed of Incorporation
     are correct and complete;

(c)  the Nitinol Deed of Incorporation has been signed by a civil law notary
     (notaris) and the contents of the Nitinol Deed of Incorporation are correct
     and complete;

(d)  the Yellow Tape Extract was true, complete and correct on the date of its
     issue and would be identical and also true, complete and correct if issued
     on, as applicable, the date of the execution of each of the Deed of Pledge,
     the Yellow Tape Resolution, the NMT Confirmation Statement and the Yellow
     Tape Power of Attorney;

(e)  the Nitinol Extract was true, complete and correct on the date of its issue
     and would be identical and also true, complete and correct if issued on, as
     applicable, the date of the execution of each of the Deed of Pledge, the
     Nitinol Resolution, the Borrower Confirmation Statement and the Nitinol
     Power of Attorney;

(f)  immediately prior to the execution of the Deed of Pledge, the information
     contained in the Yellow Tape Shareholdersregister was true and correct;

(g)  immediately prior to the execution of the Deed of Pledge, the information
     contained in the Nitinol Shareholdersregister was true and correct;

(h)  (i) each of the parties to the New York Documents and the Deed of Pledge,
     other than Yellow Tape and Nitinol, has been duly incorporated, is and at
     the time of the execution of the Deed of Pledge was validly existing and,
     to the extent relevant in such party's jurisdiction, in good standing under
     the laws applicable to such party, (ii) each of the parties to the New York
     Documents and the Deed of Pledge, other than Yellow Tape and Nitinol, has
     and had at the time of the execution of the New York Documents and the Deed
     of Pledge, all requisite power (corporate and otherwise) to execute and
     deliver, and to perform its obligations under, each of the New York
     Documents and the Deed of Pledge to which it is a party, and (iii) under
     any applicable law, other than Netherlands Law, the New York Documents and
     the Deed of Pledge have been duly executed and delivered by each of the
     parties thereto;

(i)  the New York Documents constitute under any applicable law, other than
     Netherlands Law, including the laws of the State of New York to which they
     are expressed to be subject, the valid, legal and binding obligations of
     all parties thereto, enforceable against such parties in accordance with
     their respective terms;

(j)  the jurisdiction provision in the Purchase Agreement and the Guarantee and
     Collateral Agreement is valid under the laws of the State of New York and
     the courts of the State of New York would accept jurisdiction on the basis
     thereof;

(k)  at the moment of the execution of the Deed of Pledge (i) NMT was the owner

     collateral within the meaning of Article 84, Section 2 of Volume 3 of the
     Netherlands Civil Code (the "CC");
                                  -- 

(n)  to the extent future goods (toekomstige goederen) including future
     registered claims (toekomstige vorderingen op naam) are part of the Rights
     (as defined in the Deed of Pledge), NMT or the Borrower, as applicable,
     shall at such future date be the proprietor (rechthebbende) and shall,
     under the law applicable to such Rights have the right to dispose of
     (beschikkingsbevoegdheid) and shall be validly obligated to pledge such
     Rights and such Rights shall not be encumbered by any limited rights
     (beperkte rechten) or attachments (beslagen);

(o)  the Rights (as defined in the Deed of Pledge) are capable of being pledged 
     under Netherlands Law;

(p)  the obligations under, or pursuant to, the New York Documents, to the
     extent secured by the Deed of Pledge, are sufficiently identifiable
     (voldoende bepaalbaar) within the meaning of Article 231, Section 2 of
     Volume 3 of the CC;

(q)  the Yellow Tape Resolution, the Nitinol Resolution, the NMT Confirmation

Based upon and subject to the foregoing and subject to the qualifications listed
below and to any factual matters, documents or events not disclosed to me in the
course of my examination referred to above, I am at the date hereof of the 
opinion that:

(1)  Yellow Tape has been duly incorporated and is validly existing under
     Netherlands Law as a legal entity in the form of a besloten vennootschap
     met beperkte aansprakelijkheid (closed company with limited liability).

(2)  Nitinol has been duly incorporated and is validly existing under
     Netherlands Law as a legal entity in the form of besloten vennootschap met
     beperkte aansprakelijkheid (closed company with limited liability).

(3)  Yellow Tape has the corporate power to execute, deliver and perform its 
     obligations under the Deed of Pledge.

(4)  Nitinol has the corporate power to execute, deliver and perform its 
     obligations under the Deed of Pledge.

(5)  Yellow Tape has taken all necessary corporate action to authorize the
     execution, delivery and performance of its obligations under the Deed of
     Pledge and the entry into the Deed of Pledge by Yellow Tape does not
     violate the Yellow Tape Articles of Association or any applicable provision
     of Netherlands Law.

(6)  Nitinol has taken all necessary corporate action to authorize the
     execution, delivery and performance of its obligations under the Deed of
     Pledge and the entry into the Deed of Pledge by Nitinol does not violate
     the Nitinol Articles of Association or any applicable provision of
     Netherlands Law.

(7)  The Deed of Pledge has been duly executed and delivered by Yellow Tape.

(8)  The Deed of Pledge has been duly executed and delivered by Nitinol.

                                                                             -9-
 
(9)  The Deed of Pledge creates a valid first ranking right of pledge (eerste
     pandrecht) on the Shares and the Rights as defined therein, in favor of
     Agent, which right of pledge is enforceable in the Netherlands in
     accordance with its terms and the applicable provisions of Netherlands Law.

The opinions expressed above are subject to the following qualifications:

(A)  The opinions expressed in paragraphs (3) and (4) above are limited by any
     applicable bankruptcy, insolvency, reorganization, moratorium and other
     similar laws of general application at the time of the execution of the
     Deed of Pledge, now or hereafter in effect, relating to or effecting the
     enforcement or protection of creditors' rights.

(B)  The enforcement of the pledge created pursuant to the Deed of Pledge will
     not be affected by the bankruptcy (faillissement) or suspension of payments
     (surseance van betaling) of Yellow Tape or Nitinol, provided that (i) a
     receiver in bankruptcy (curator) may require the holder of such pledge to
     foreclose it within a reasonable time, and if such holder fails to do so
     the receiver can sell the underlying assets himself and pay the proceeds to
     such holder, and (ii) the foreclosure of such pledge can be suspended by a
     court, at the request of any interested party, for a period not exceeding
     two months.

(C)  Any opinions expressed herein with respect to the validity of the Deed of
     Pledge or any legal act (rechtshandeling) forming part thereof or
     contemplated thereby are limited by the protection afforded by Netherlands
     Law pursuant to rules regarding fraudulent conveyance (Actio Pauliana) to
     creditors whose interests have been injured.

(D)  The obligations of a party to an agreement, to the extent Netherlands Law
     is applicable, are subject to and limited by rules of force majeure (niet
     toerekenbare tekortkoming), set-off, reasonableness and fairness
     (redelijkheid en billijkheid), unforeseen circumstances (onvoorziene
     omstandigheden) and other defenses afforded by Netherlands Law to obligors
     generally. Under Netherlands Law the remedy of specific performance may not
     always and in all circumstances be available.

(E)  The opinion expressed in paragraph (9) above is limited to the extent that 
     (i) no opinion is rendered that the rights of pledge created by means of
     the Deed of Pledge can be enforced in any jurisdiction other than the
     Netherlands and that such other jurisdiction would recognize, give such
     effect or grant such priority to such rights of pledge as would be the case
     in the Netherlands and (ii) the foreclosure under the rights of pledge, 
     created by the Deed of Pledge, will be subject to certain mandatory share
     transfer restrictions (blokkeringsregelingen) in Article 5 of the Yellow
     Tape Articles of Association and Article 8 of the Nitinol Articles of
     Association.

(F)  I do not render any opinion on the recognition or enforceability in the 
     Netherlands of the security interests purporting to be created pursuant to
     the New York Documents.

(G)  To the extent Netherlands Law is applicable, any provision in the New York 
     Documents or the Deed of Pledge to the effect that such agreement or any of
     the provisions thereof shall be binding on the successors or assigns of any
     party thereto may not be valid in the absence of an agreement with any such
     assign or successor.

(H)  Any substitution of the Agent as contemplated in Section 8.5 of the 
     Guarantee and Collateral Agreement (Successors and Assigns) will result in
     the former Agent losing the benefit of the Deed of Pledge without the
     substitute agent acquiring such benefits. Consequently, in the event of
     such substitution, (a) the security interests created in favor of the Agent
     pursuant to the Deed of Pledge and (b) the right to administer (beheren)
     and dispose of (beschikken) the rights in respects of the Shares (as
     referred to in the Deed of Pledge) and the Rights (as referred to in the
     Deed of Pledge) will need to be re-established by way of the re-execution
     of a replacement Deed of Pledge.

(I)  In accordance with Netherlands law a power of attorney can only be made
     irrevocable to the extent its object is the performance of
     rechtshandelingen (juridical acts) in the interest of the representative
     appointed thereby or of a third party. In accordance with Netherlands law
     any power of attorney or mandate will terminate upon the faillissement
     (bankruptcy) or becomes ineffective upon the surseance van betaling
     (suspension of payments) of the issuer thereof.

(J)  Pursuant to Article 7 Volume 2 of the CC any transactions entered in to by
     a legal entity (such as Yellow Tape and Nitinol) may be nullified if the
     objects of such entity were transgressed thereby and the other party to the
     transaction knew or should have known this without independent
     investigation. The description of the objects of Yellow Tape in Article 2
     of the Yellow Tape Articles of Association include "... to provide security
     for the debts of legal persons or of other companies with which the company
     is affiliated in a group..." and the description of the objects of Nitinol
     in Article 2 of the Nitinol Articles of Association include "... to provide
     guarantees and to bind the company, or assets of the company, for the
     benefit of enterprises and corporations with which the company is
     affiliated in a group...". However, there is no case law confirming that
     this fact alone is sufficient to conclude that the granting of such
     security, would not be ultra vires. The view is widely expressed in the
     literature that a transaction which patently violates the interest of a
     company is ultra vires regardless of the description of the objects in its
     article of association.


The opinion speaks as of its date. It is addressed solely to you and your 
permitted successors, transferees and assigns. It may not be relied upon by any
person other than you and without my prior written consent, its contents may not
be disclosed to third parties, save to Yellow Tape's and Nitinol's law legal 
advisor who may rely upon this opinion as though it were addressed to him.


                                           Sincerely,

4.   THE AGENT'S POWERS

     The Agent shall have the powers set out in Schedule 3 (The Agent's Powers).

5    CONTINUING SECURITY

5.1  CONTINUING SECURITY

     This Charge is a continuing security and shall secure the ultimate balance
     of the Borrower Obligations, notwithstanding intermediate payment or
     discharge of the whole or part of the Borrower Obligations to the Agent and
     also notwithstanding liquidation or other incapacity of the Chargor or the
     Company, or any change in the constitution, name or style of the Chargor or
     the Company or any other event, matter or thing.

5.2  ADDITIONAL TO OTHER RIGHTS

     This Charge is in addition to (and shall not merge with, otherwise
     prejudice or affect or be prejudiced or affected by) any other remedy,
     guarantee, indemnity, Security Interest or other right or interest which
     may be or have been created in favour of the Agent in respect of the
     Borrower Obligations. Accordingly, this Charge may be enforced
     notwithstanding:

     (a)  the existence or invalidity of all or any of those rights and
          interests; and

     (b)  the Agent or any of the Lenders at any time exchanging, releasing,

     security or payment shall be conditional on the assurance, security or
     payment not being avoided, reduced, clawed back or ordered to be repaid
     under any enactment relating to liquidation, bankruptcy or insolvency. If
     any avoidance, clawback or reduction occurs or such order is made, the
     release given by the Agent shall have no effect and shall not prejudice

     Obligations and, as between the Chargor and the Agent, this Charge shall
     (notwithstanding the release) be deemed to have remained at all times in
     effect and held by the Agent as security for the Borrower Obligations.

6.2  RETENTION

     Unless and until the Agent, acting reasonably, is satisfied as to the
     solvency of the Chargor, the Agent may retain this Charge after the
     payment, discharge or satisfaction of all of the Borrower Obligations and
     notwithstanding any such payment, discharge or satisfaction for such period
     as the Agent, acting reasonably, may consider that any such payment,
     release or discharge is susceptible of being avoided, reduced or ordered to
     be repaid under any enactment relating to liquidation, bankruptcy or
     insolvency. In the event of the commencement of the bankruptcy or winding-
     up of the person making such payment or effecting such discharge or
     satisfaction at any time within that period, the Agent shall be entitled to
     retain any such security for such further period as the Agent, acting
     reasonably, may determine.

7.   THIRD PARTY PROTECTION

     No purchaser, mortgagee or other person dealing with the Agent shall be
     concerned:

     (a)  to enquire whether any of the Borrower Obligations have become due or
          payable or remain unpaid or undischarged or whether the power which
          the Agent is purporting to exercise has become exercisable: or

     (b)  to see to the application of any money paid to the Agent.

8.   INDEMNITIES

8.1  COSTS AND EXPENSES

     The Chargor shall indemnify the Agent fully (and in the case of legal costs
     and expenses on a solicitor and own client basis, such legal costs and
     expenses where incurred prior to an enforcement of this Charge to be
     limited to reasonable legal costs and expenses) on demand against all
     Losses incurred by (or made or brought against) it (or any manager or agent
     appointed by it or him) except Losses arising from a wilful misconduct or
     gross negligence of the Agent or any Lender:

     (a)  as a result of any failure by the Chargor to perform any of its
          obligations under this Charge;

     (b)  in the exercise (or purported exercise) of any of the powers or rights
          conferred by this Charge or by any other Security Interest granted
          (whether by the Chargor, the Company or any third party) for all or
          part of the Borrower Obligations; or

     (c)  for any other matter or thing done or omitted relating to the Charged
          Securities or the assets secured by any such other Security Interest,

8.2  CURRENCY INDEMNITY

(1)  Any payment by the Chargor under this Charge shall be made in the currency
     (in this Clause 8.2 the "CONTRACTUAL CURRENCY") in which the relevant
     Borrower Obligations were denominated or incurred. If in respect of any of
     the Borrower Obligations the Agent receives payment or that Borrower
     Obligation is converted into a claim, proof, judgment or order, in either
     case in a currency other than the Contractual Currency, then:

     (a)  the Chargor shall indemnify the Agent against any loss or liability
          directly resulting from the conversion;

     (b)  if the amount received by the Agent, when converted into the
          Contractual Currency by the Agent, is less than the amount of the
          relevant Borrower Obligation in the Contractual Currency, then the
          Chargor shall on demand pay to the Agent an amount in the Contractual
          Currency equal to the difference; and

     (c)  the Chargor shall on demand pay to the Agent any exchange costs and
          taxes payable in Connection with any conversion referred to in this
          Clause 8.2.

(2)  If and to the extent that the Chargor fails to pay on demand any amount due
     under this Charge, the Agent may in its absolute discretion (and without
     notice to the Chargor) purchase at any time after that so much of a
     currency as the Agent considers necessary or desirable to cover any part of
     the Borrower Obligations denominated or incurred in such currency.  That
     purchase shall be made at the then-prevailing spot rate of exchange
     obtained by the Agent (as conclusively determined by the Agent) for
     purchasing such currency with sterling. The Chargor agrees to indemnify
     the Agent against the full sterling price (including all costs, charges
     and expenses) paid by the Agent for such currency.

(3)  All moneys received or held by the Agent from the Chargor or under this
     Charge may from time to time be converted into such other currency as the
     Agent considers necessary or desirable to cover any part of the Borrower
     Obligations denominated or incurred in that currency. That conversion shall
     be made at the then-prevailing spot rate of exchange obtained by the Agent
     (as conclusively determined by the Agent) for purchasing tile currency to
     be acquired with the existing currency.

9.   SEVERABILITY

     If any part of any provision of this Charge shall be or become invalid or
     unenforceable under any applicable law, then the remainder of that
     provision and all other provisions of this Charge shall remain valid and
     enforceable.

      waiver of that right. Rather, any such waiver or release must be
      specifically granted in writing signed by an authorised signatory of the
      Agent and shall:

      (a)  be confined to the specific circumstances in which it is given;

      (b)  not affect any other enforcement of the same or any other right; and

           in writing.

      reasonably thinks fit.

          FOR VALUE RECEIVED. the undersigned, NITINOL MEDICAL TECHNOLOGIES,
INC., a Delaware corporation (the "BORROWER") hereby promises to pay to the
order of Whitney Subordinated Debt Fund, L.P. ("WSDF"), a Delaware limited
partnership, or its registered assigns (the "HOLDER"), the principal sum of
TWENTY MILLION DOLLARS ($20,000,000) on September, 2003 (the "MATURITY DATE"),

               ------------------

hereby and thereby or otherwise available in respect hereto and thereto.
Capitalized terms used herein without definition are used herein with the
meanings ascribed to such terms in the Purchase Agreement.

          2.   Interest.  The Borrower promises to pay interest on the principal
               --------                                                         
amount of this Note at the rate of 10.101% per annum.  The Borrower shall pay
accrued interest quarterly on each March 31, June 30, September 30 and December
31 of each year or, if any such date shall not be a Business Day, on the next
succeeding Business Day to occur after such date (each date upon which interest
shall be so payable, an "INTEREST PAYMENT DATE"), beginning on September 30,
1998; provided, however, that notwithstanding anything to the contrary contained
      --------  -------                                                         
herein or in the Purchase Agreement, the interest accruing under this Note in
respect of the quarterly periods ending September 30, 1998, December 31, 1998
and March 31, 1999 (other than additional interest incurred upon and during the
occurrence of an Event of Default) shall be satisfied as specified in Section
8.10 of the Purchase Agreement.  Interest on this Note shall be paid by wire
transfer of immediately available funds to an account at a bank designated by
the Holder.  Interest on this Note shall accrue from the date of issuance until
repayment of the principal and payment of all accrued interest in full.
Interest shall accrue and be computed on the basis of a 360-day year of twelve
30-day months. Notwithstanding the foregoing provisions of this Section 2, but
subject to applicable law, any overdue principal of and overdue interest on this
Note shall bear interest, payable on demand in immediately available funds, for
each day from the date payment thereof was due to the date of actual payment, at
a rate equal to the rate of interest otherwise in effect pursuant to the first
sentence of this Section 2 plus 2% per annum, and, upon and during the
                           ----                                       
occurrence of an Event of Default (as hereinafter defined) (other than an Event
of Default pursuant to Section 6(a)(ii) of this Note), this Note shall bear
interest, from the date of the occurrence of such Event of Default until such
Event of Default is cured or waived, payable on demand in immediately available
funds, at a rate equal to the rate of interest otherwise in effect pursuant to
the first sentence of this Section 2 plus 2% per annum.  Subject to applicable
                                     ----                                     
law, any interest that shall accrue on overdue interest on this Note as provided
in the preceding sentence and shall not have been paid in full on or before the
next Interest Payment Date to occur after the Interest Payment Date on which the
overdue interest became due and payable shall itself be deemed to be overdue
interest on this Note to which the preceding sentence shall apply.  In the event
that any interest rate provided for herein shall be determined to be unlawful,
such interest rate shall be computed at the highest rate permitted by applicable
law.  Any payment by the Borrower of any interest amount in excess of that
permitted by law shall be considered a mistake, with the excess being applied to
the principal of this Note without prepayment premium or penalty.

          (b) Acceleration.  If an Event of Default occurs under Section
              ------------                                              
6(a)(viii) or (ix), then the outstanding principal of and all accrued interest
on this Note 

                                       6
<PAGE>
 
shall automatically become immediately due and payable, without
presentment, demand, protest or notice of any kind, all of which are hereby
expressly waived.  If any other Event of Default occurs and is continuing the
Holder, by written notice to the Borrower may declare the principal of and
accrued interest on this Note to be immediately due and payable.  Upon such
declaration, such principal and interest shall become immediately due and
payable.  The Holder shall rescind an acceleration and its consequences if all
existing Events of Default have been cured or waived, except nonpayment of
principal or interest that has become due solely because of the acceleration,
and if the rescission would not conflict with any judgment or decree.  Any
notice or rescission shall be given in the manner specified in Section 11.3 of
the Purchase Agreement.

          7.   Subordination.  Subject to the limitations set forth in Section
               -------------                                                  
7(o) below, this Note shall at all times be wholly subordinate and junior in
right of payment to all Senior Indebtedness to the extent and in the manner
provided in this Section 7.

          (a) Definitions.  As used in this Section 7, the following terms
              -----------

extensions, refinancings, modifications or refundings thereof, provided,
                                                               -------- 
however, in no event shall the aggregate principal amount of Senior Indebtedness
- -------

time, acceleration, required prepayment or otherwise, all Senior Indebtedness
shall first be paid in full, or such payment duly provided for in cash or in a
manner

                                       7
<PAGE>
 
satisfactory to the holders of such Senior Indebtedness, before any payment is
made on account of the Subordinated Indebtedness or by the Borrower or an
Affiliate of the Borrower to acquire this Note, except that (i) the Borrower may
prepay this Note in accordance with the provisions of Section 3 or Section 4 so
long as no Senior Default has occurred and is continuing or would occur as a
result of any such prepayment and (ii) the Holder may receive any distributions
provided for in Section 7(e)(ii) or 7(e)(iv) hereof.

          (c)  Limitation on Payment.
               --------------------- 

                    (i) Upon receipt by the Borrower and the Holder of a
Blockage Notice (as defined below), then unless and until (1) all Senior
Defaults that gave rise to the Blockage Notice shall have been remedied or
effectively waived or shall have ceased to exist, or (2) the Senior Indebtedness
in respect of which such Senior Defaults shall have occurred shall have been
paid in full, no direct or indirect payment (in cash, property, securities or by
set-off or otherwise) of or on account of the principal of or interest on this
Note or as a sinking fund for this Note or in respect of any redemption,
retirement, purchase or other acquisition of this Note shall be made during any
period prior to the expiration of the Blockage Period (as defined below).
Notwithstanding the foregoing, all interest paid with respect to this Note prior
to the receipt of the Blockage Notice in question by the Holder hereof may be
kept by such Holder.

                    (ii) For purposes of this Section 7, a "BLOCKAGE NOTICE" is
a notice of a Senior Default that in fact has occurred and is continuing, given
to the Borrower and the Holder by the holders of a majority in principal amount
of the Senior Indebtedness then outstanding (or their authorized agent);
                                                                        
provided, however, that no such notice shall be effective as a Blockage Notice
- --------  -------                                                             
if an effective Blockage Notice shall have been given within 360 days prior
thereto.

                    (iii) For purposes of this Section 7, a "BLOCKAGE PERIOD"
with respect to a Blockage Notice is the period commencing upon the Borrower's
receipt of such Blockage Notice and having a duration as follows:

                    (1) 60 days if the Senior Default to which the Blockage
          Notice refers is a Senior Payment Default; or

                    (2) 30 days if the Senior Default to which the Blockage
          Notice refers is a Senior Covenant Default.

          (d) Limitation on Remedies.  As long as any Senior Indebted ness
              ----------------------                                      
remains outstanding, upon the occurrence of an Event of Default under this Note,
the Holder shall not, unless the holders of any Senior Indebtedness shall have
caused such Senior Indebtedness to become due prior to its stated maturity or
any Event of Default pursuant to Section 6(a)(viii) or (ix) of this Note shall
have commenced, declare

                                       8
<PAGE>
 
or join in any declaration of this Note to be due and payable by reason of such
Event of Default or otherwise take any action against the Borrower (including,
without limitation, commencing any legal action against the Borrower or filing
or joining in the filing of any insolvency petition against the Borrower) prior
to the expiration of 30 days after the written notice of intention to accelerate
on account of the occurrence of such Event of Default (a "REMEDY NOTICE") shall
have been given by the Holder to the Borrower and the holders of the Senior
Indebtedness (a "REMEDY STANDSTILL PERIOD"), provided, that such Remedy
Standstill Period shall be extended (i) to 60 days from the date of such Remedy
Notice if, at the time the Remedy Standstill Period would otherwise expire,
there exists any Senior Covenant Default and (ii) to 90 days from the date of
such Remedy Notice if, at the time the Remedy Standstill Period would otherwise
expire, there exists any Senior Payment Default.

          Notwithstanding the foregoing, the Blockage Period shall be
inapplicable or cease to be effective if an Event of Default pursuant to Section
6(a)(viii) or (ix) shall have occurred.  In addition, any Blockage Period shall
cease to be effective if at any time during such period: (i) substantial assets
of the Borrower, its parent or its Subsidiaries are sold or otherwise disposed
of outside of the ordinary course of business for less than fair value or (ii)
payment or any distribution of any character, whether in cash, securities or
other property of the Borrower, its parent or its Subsidiaries shall be made to
or received by any creditor on any Indebtedness which is on the same level of
priority with or junior and subordinate in right of payment to this Note.

          Upon the expiration or termination of any Blockage Period and/or any
Remedy Standstill Period, the Holder shall be entitled to exercise any of its
rights with respect to this Note other than any right to accelerate the maturity
date of this Note based upon the occurrence of any Event of Default in respect
thereto which has been cured or otherwise remedied during the Blockage Period.

          (e) Subordination Upon Certain Events.  Upon the occurrence of any
              ---------------------------------                             
Event of Default with respect to the Borrower under Sections 6(a)(viii) or (ix)
of this Note:

                    (i) Upon any payment or distribution of assets of the
Borrower to creditors of such Borrower, holders of Senior Indebtedness shall be
entitled to receive indefeasible payment in full of all obligations with respect
to the Senior Indebtedness before the Holder shall be entitled to receive any
payment in respect of the Subordinated Indebtedness.

                    (ii) Until all Senior Indebtedness is paid in full, any
distribution to which the Holder would be entitled but for this Section 7 shall
be made to the holders of Senior Indebtedness, as their interests may appear,
except that the Holder may, pursuant to a plan of reorganization under Chapter
11 of the Bankruptcy Code of 1978, as amended, or any similar provision of any
successor legislation thereto, receive securities that are subordinate to the
Senior Indebtedness to at least the same

                                       9
<PAGE>
 
extent as this Note if pursuant to such plan the distributions to the holders of
the Senior Indebtedness in the form of cash, securities or other property, by
set-off or otherwise, provide for payment of the full amount of the allowed
claim of the holders of the Senior Indebtedness.

                    (iii) For purposes of this Section 7, a distribution may
consist of cash, securities or other property, by set-off or otherwise.

                    (iv) Notwithstanding the foregoing provisions of Section
7(b),(c) or (e), if payment or delivery by the Borrower of cash, securities or
other property to the Holder is authorized by an order or decree giving effect,
and stating in such order or decree that effect is given, to the subordination
of this Note to the Senior Indebtedness, and made by a court of competent
jurisdiction in a proceeding under any applicable bankruptcy or reorganization
law, payment or delivery by such Borrower of such cash, securities or other
property shall be made to the Holder in accordance with such order or decree.

          (f) Payments and Distributions Received.  If the Holder shall have
              -----------------------------------                           
received any payment from or distribution of assets of the Borrower in respect
of the Subordinated Indebtedness in contravention of the terms of this Section 7
before all Senior Indebtedness is paid in full, then and in such event such
payment or distribution shall be received and held in trust for and shall be
promptly paid over or delivered to the holders of Senior Indebtedness to the
extent necessary to pay all such Senior Indebtedness in full.

          (g) Proofs of Claim.  If, while any Senior Indebtedness is
              ---------------                                       
outstanding, any Event of Default under Section 6(a)(viii) or (ix) of this Note
occurs with respect to the Borrower (but not of any one Subsidiary, the
operations of which in the reasonable judgment of the Holder is not material to
the operations of the Borrower, its parent and all Subsidiaries taken as a
whole), the Holder shall duly and promptly take such action as any holder of
Senior Indebtedness may reasonably request to collect any payment with respect
to this Note for the account of the holders of the Senior Indebtedness and to
file appropriate claims or proofs of claim in respect of this Note. Upon the
failure of the Holder to take any such action, each holder of Senior
Indebtedness is hereby irrevocably authorized and empowered (in its own name or
otherwise), but shall have no obligation, to demand, sue for, collect and
receive every payment or distribution referred to in respect of this Note and to
file claims and proofs of claim and take such other action as it may deem
necessary or advisable for the exercise or enforcement of any of the rights or
interests of the holder with respect to this Note.

          (h) Subrogation.  After all amounts payable under or in respect of
              -----------                                                   
Senior Indebtedness are paid in full, the Holder shall be subrogated to the
rights of holders of Senior Indebtedness to receive payments or distributions
applicable to Senior Indebtedness to the extent that distributions otherwise
payable to the Holder have been

                                       10
<PAGE>
 
applied to the payment of Senior Indebtedness. A distribution made under this
Section 7 to a holder of Senior Indebtedness which otherwise would have been
made to the Holder is not, as between the Borrower and the Holder, a payment by
the Borrower on the Indebtedness held by the Holder.

          (i) Relative Rights.  This Section defines the relative rights of the
              ---------------                                                  
Holder and the holders of Senior Indebtedness.  Nothing in this Section shall:
(1) impair, as between the Borrower and the Holder, the obligation of the
Borrower, which is absolute and unconditional, to pay principal of and interest
(including default interest) on this Note in accordance with its terms; (2)
affect the relative rights of the Holder and creditors of the Borrower other
than holders of Senior Indebtedness or (3) prevent the Holder from exercising
its available remedies upon a default or Event of Default, subject to the
rights, if any, under this Section 7 of holders of Senior Indebtedness.

          (j) Subordination May Not Be Impaired by the Borrower.  No right of
              -------------------------------------------------              
any holder of any Senior Indebtedness to enforce the subordination of the
Indebtedness evidenced by this Note shall be impaired by any failure to act by
the Borrower or by the failure of the Borrower to comply with this Note.  The
provisions of this Section 7 shall continue to be effective or be reinstated, as
the case may be, if at any time any payment of any of the Senior Indebtedness is
rescinded or must otherwise be returned by any holder of Senior Indebtedness as
a result of the insolvency, bankruptcy or reorganization of the Borrower or any
of its Subsidiaries or otherwise, all as though such payment had not been made.

          (k) Payments.  A payment with respect to principal of or interest on
              --------                                                        
the Subordinated Indebtedness shall include, without limitation, payment of
principal of, and interest on this Note, any depositing of funds for the
defeasance of the Subordinated Indebtedness, any sinking fund and any payment on
account of mandatory prepayment or optional prepayment provisions.

          (l) Section Not to Prevent Events of Default.  The failure to make a
              ----------------------------------------                        
payment on account of principal of or interest on or other amounts constituting
Subordinated Indebtedness by reason of any provision of this Section 7 shall not
be construed as preventing the occurrence of an Event of Default under Section
6.

          (m) Subordination Not Impaired: Benefit of Subordination.  The Holder
              ----------------------------------------------------             
agrees and consents that without notice to or assent by such Holder, and without
affecting the liabilities and obligations of the Borrower and the rights and
benefits of the holders of the Senior Indebtedness set forth in this Section 7:

                    (i) The obligations and liabilities of the Borrower and any
other party or parties for or upon the Senior Indebtedness may, from time to
time, be increased, renewed, refinanced, extended, modified, amended, restated,
compromised, supplemented, terminated, waived or released, except as prohibited
by Sections 9.3 and 9.4 of the Purchase Agreement;

                                       11
<PAGE>
 
                    (ii) The holders of Senior Indebtedness, and any
representative or representatives acting on behalf thereof, may exercise or
refrain from exercising any right, remedy or power granted by or in connection
with any agreements relating to the Senior Indebtedness; and

                    (iii) Any balance or balances of funds with any holder of
Senior Indebtedness at any time outstanding to the credit of the Borrower may,
from time to time, in whole or in part, be surrendered or released;

all as the holders of the Senior Indebtedness, and any representative or
representatives acting on behalf thereof, may deem advisable, and all without
impairing, abridging, diminishing, releasing or affecting the subordination of
the Subordinated Indebtedness to the Senior Indebtedness provided for herein.

          (n) Modification of Section 7. The provisions of this Section 7 are
              -------------------------                                      
for the benefit of the holders from time to time of Senior Indebtedness and, so
long as any Senior Indebtedness remains unpaid, may not be modified, rescinded
or canceled in whole or in part without the prior written consent thereto of all
holders of Senior Indebtedness.

          (o)  Miscellaneous.
               ------------- 

                    (i) To the extent permitted by applicable law, the Holder
and the Borrower hereby waive (1) notice of acceptance hereof by the holders of
the Senior Indebtedness, and (2) all diligence in the collection or protection
of or realization upon the Senior Indebtedness.

                    (ii) The Borrower and the Holder hereby expressly agree that
the holders of Senior Indebtedness may enforce any and all rights derived herein
by suit, either in equity or law, for specific performance of any agreement
contained in this Section 7 or for judgment at law and any other relief
whatsoever appropriate to such action or procedure.

                    (iii) The Holder acknowledges and agrees that the foregoing
subordination provisions are, and are intended to be, an inducement and a
consideration to each holder of Senior Indebtedness, whether such Senior
Indebtedness was created or acquired before or after the issuance of this
Agreement, and each holder of Senior Indebtedness shall be deemed conclusively
to have relied upon such subordination provisions in acquiring and continuing to
hold such Senior Indebtedness.

          8.   Use of Proceeds.  The Borrower shall use the principal from this
               ---------------                                                 
Note (a) for the payment of fees and expenses in connection with the
transactions contemplated under Transaction Documents and (b) to fund the
purchase price of the Acquisition under Elekta Purchase Agreement.

          9.   Suits for Enforcement.
               --------------------- 

               (a) Subject to Section 7, upon the occurrence of any one or more
Events of Default, the Holder of this Note may proceed to protect and enforce
its rights hereunder by suit in equity, action at law or by other appropriate
proceeding, whether for the specific performance of any covenant or agreement
contained in the Purchase Agreement or this Note or in aid of the exercise of
any power granted in the Purchase Agreement or this Note, or may proceed to
enforce the payment of this Note, or to enforce any other legal or equitable

and expenses of such Holder due to such default, as provided in Article 7 of the

               --------------------

hereunder shall operate as a waiver of any right.

          12.  Transfer.
               -------- 

               (a) The term "HOLDER" as used herein shall also include any
transferee of this Note whose name has been recorded by the Borrower in the Note
Register. Each transferee of this Note acknowledges that this Note has not been
registered under the Securities Act, and may be transferred only pursuant to an
effective registration under the Securities Act or pursuant to an applicable
exemption from the registration requirements of the Securities Act.

               (b) The Borrower shall maintain a register (the "NOTE REGISTER")
in its principal offices for the purpose of registering the Note and any
transfer thereof, which register shall reflect and identify, at all times, the
ownership of any interest in the Note. Upon the issuance of this Note, the
Borrower shall record the name of the initial purchaser of this Note in the Note
Register as the first Holder. Upon surrender for registration of transfer or
exchange of this Note at the principal offices of the Borrower, the Borrower
shall, at its expense, execute and deliver one or more new Notes of like tenor
and of denominations of at least $500,000 (except as may be necessary to reflect
any principal amount not evenly divisible by $500,000) of a like aggregate
principal amount, registered in the name of the Holder or a transferee or
transferees. Every Note surrendered for registration of transfer or exchange
shall be duly endorsed, or be

                                       13

loss, theft, destruction or mutilation of this Note (and in the case of any such
mutilation, on surrender and cancellation of such Note), the Borrower, at its
expense, will promptly execute and deliver, in lieu thereof, a new Note of like
tenor.  If required by the Borrower, such Holder must provide an indemnity bond
or other indemnity sufficient in the judgment of the Borrower to protect the
Borrower from any loss which it may suffer if a lost, stolen or destroyed Note
is replaced.

          14.  Covenants Bind Successors and Assigns.  All the covenants,
               -------------------------------------

                             SECTION 2. GUARANTEE

          2.1 Guarantee.  (a)  Each of the Guarantors hereby, jointly and
              ---------                                                  
severally, unconditionally and irrevocably, guarantees to the Agent, for the
benefit of the Lenders and their respective successors, indorsees, transferees
and assigns, the prompt and complete payment and performance by the Borrower
when due (whether at the stated maturity, by acceleration or otherwise) of the
Borrower Obligations.

          (b) Anything herein or in any other Loan Document to the contrary
notwithstanding, the maximum liability of each Guarantor hereunder and under the
other Loan Documents shall in no event exceed the amount which can be guaranteed
by such Guarantor under applicable federal and state laws relating to the
insolvency of debtors (after giving effect to the right of contribution
established in Section 2.2).

          (c) Each Guarantor agrees that the Borrower Obligations may at any
time and from time to time exceed the amount of the liability of such Guarantor
hereunder without impairing the guarantee contained in this Section 2 or
affecting the rights and remedies of the Agent or any Lender hereunder.

          (d) The guarantee contained in this Section 2 shall remain in full
force and effect until all the Borrower Obligations and the obligations of each
Guarantor under the guarantee contained in this Section 2 shall have been
satisfied by payment in full.

          (e) No payment made by the Borrower, any of the Guarantors, any other
guarantor or any other Person or received or collected by the Agent or any
Lender from the Borrower, any of the Guarantors, any other guarantor or any
other Person by virtue of any action or proceeding or any set-off or
appropriation or application at any time or from time to time in reduction of or
in payment of the Borrower Obligations shall be deemed to modify, reduce,
release or otherwise affect the liability of any Guarantor hereunder which
shall, notwithstanding any such payment (other than any payment made by such
Guarantor in respect of the Borrower Obligations or any payment received or
collected from such Guarantor in respect of the Borrower Obligations), remain
liable for the Borrower Obligations up to the maximum liability of such
Guarantor hereunder until the Borrower Obligations are Fully Satisfied.

          2.2 Right of Contribution.  Each Guarantor hereby agrees that to the
              ---------------------                                           
extent that a Guarantor shall have paid more than its proportionate share of any
payment made hereunder, such Guarantor shall be entitled to seek and receive
contribution from and against any other Guarantor hereunder which has not paid
its proportionate share of such payment.  Each Guarantor's right of contribution
shall be subject to the terms and conditions of Section 2.3. The provisions of
this Section 2.2 shall in no respect limit the obligations and liabilities of
any Guarantor to the Agent and the Lenders, and each Guarantor shall remain
liable to the Agent and the Lenders for the full amount guaranteed by such
Guarantor hereunder.

          2.3 No Subrogation.  Notwithstanding any payment made by any Guarantor
              --------------                                                    
hereunder or any set-off or application of funds of any Guarantor by the Agent
or any Lender, no Guarantor shall be entitled to be subrogated to any of the
rights of the Agent or any Lender against the Borrower or any other Guarantor or
any collateral security or guarantee or right of offset held by the Agent or any
Lender for the payment of the Borrower Obligations, nor shall any Guarantor seek
or be entitled to seek any contribution or reimbursement from the Borrower or
any other Guarantor in respect of payments made by such Guarantor hereunder,
until all amounts owing to the Agent and the Lenders by the Borrower on account
of the Borrower Obligations are Fully Satisfied.  If any amount shall be paid to
any Guarantor on account of such subrogation rights at any time when all of the
Borrower Obligations shall not have been Fully Satisfied, such amount shall be
held by such Guarantor in trust for the Agent and the Lenders, segregated from
other funds of such Guarantor, and shall, forthwith upon receipt by such
Guarantor, be turned over to the Agent in the exact form received by such
Guarantor (duly indorsed by such Guarantor to the Agent, if required), to be
applied against the Borrower Obligations, whether matured or unmatured, in such
order as the Agent may determine.

          2.4 Amendments, etc. with respect to the Borrower Obligations. Each
              ---------------------------------------------------------      
Guarantor shall remain obligated hereunder notwithstanding that, without any
reservation of rights against any Guarantor and without notice to or further
assent by any Guarantor, any demand for payment of any of the Borrower
Obligations made by the Agent or any Lender may be rescinded by the Agent or
such Lender and any of the Borrower Obligations continued, and the Borrower
Obligations, or the liability of any other Person upon or for any part thereof,
or any collateral security or guarantee therefor or right of offset with respect
thereto, may, from time to time, in whole or in part, be renewed, extended,
amended, modified, accelerated, compromised, waived, surrendered or released by
the Agent or any Lender, and the Note Purchase Agreement and the other Loan
Documents and any other documents executed and delivered in connection therewith
may be amended, modified, supplemented or terminated, in whole or in part, as
the Agent (or the Lenders pursuant to the Note Purchase Agreement, as the case
may be) may deem advisable from time to time, and any collateral security,
guarantee or right of offset at any time held by the Agent or any Lender for the

                                       7
<PAGE>
 
payment of the Borrower Obligations may be sold, exchanged, waived, surrendered
or released.  Neither the Agent nor any Lender shall have any obligation to
protect, secure, perfect or insure any Lien at any time held by it as security
for the Borrower Obligations or for the guarantee contained in this Section 2 or
any property subject thereto.

          2.5 Guarantee Absolute and Unconditional.  Each Guarantor waives any
              ------------------------------------                            
and all notice of the creation, renewal, extension or accrual of any of the
Borrower Obligations and notice of or proof of reliance by the Agent or any
Lender upon the guarantee contained in this Section 2, or acceptance of the
guarantee contained in this Section 2.  The Borrower Obligations, and any of
them, shall conclusively be deemed to have been created, contracted or incurred,
or renewed, extended, amended or waived, in reliance upon the guarantee
contained in this Section 2.  All dealings between the Borrower and any of the
Guarantors, on the one hand, and the Agent and the Lenders, on the other hand,
likewise shall be conclusively presumed to have been had or consummated in
reliance upon the guarantee contained in this Section 2.  Each Guarantor waives
diligence, presentment, protest, demand for payment and notice of default or
nonpayment to or upon the Borrower or any of the Guarantors with respect to the
Borrower Obligations.  Each Guarantor understands and agrees that the guarantee
contained in this Section 2 shall be construed as a continuing, absolute and
unconditional guarantee of payment without regard to (a) the validity or
enforceability of the Note Purchase Agreement or any other Loan Document, any of
the Borrower Obligations or any other collateral security therefor or guarantee
or right of offset with respect thereto at any time or from time to time held by
the Agent or any Lender, (b) any defense, set-off or counterclaim (other than a
defense of payment or performance) which may at any time be available to or be
asserted by the Borrower or any other Person against the Agent or any Lender, or
(c) any other circumstance whatsoever (with or without notice to or knowledge of
the Borrower or such Guarantor) which constitutes, or might be construed to
constitute, an equitable or legal discharge of the Borrower for the Borrower
Obligations, or of such Guarantor under the guarantee contained in this Section
2, in bankruptcy or in any other instance.  When making any demand hereunder or
otherwise pursuing its rights and remedies hereunder against any Guarantor, the
Agent or any Lender may, but shall be under no obligation to, make a similar
demand on or otherwise pursue such rights and remedies as it may have against
the Borrower, any other Guarantor or any other Person or against any collateral
security or guarantee for the Borrower Obligations or any right of offset with
respect thereto, and any failure by the Agent or any Lender to make any such
demand, to pursue such other rights or remedies or to collect any payments from
the Borrower, any other Guarantor or any other Person or to realize upon any
such collateral security or guarantee or to exercise any such right of offset,
or any release of the Borrower, any other Guarantor or any other Person or any
such collateral security, guarantee or right of offset shall not relieve any
Guarantor of any obligation or liability hereunder, and shall not impair or
affect the rights and remedies, whether express, implied or available 

                                       8

as a matter of law, of the Agent or any Lender against any Guarantor. For the
purposes hereof "demand" shall include the commencement and continuance of any
legal proceedings.

          2.6 Reinstatement.  The guarantee contained in this Section 2 shall
              -------------                                                  
continue to be effective, or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any of the Borrower Obligations is rescinded or
must otherwise be restored or returned by the Agent or any Lender upon the
insolvency, bankruptcy, dissolution, liquidation or reorganization of the
Borrower or any Guarantor, or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for, the
Borrower or any Guarantor or any substantial part of its property, or otherwise,
all as though such payments had not been made.

          2.7 Payments.  Each Guarantor hereby guarantees that payments
              --------                                                 
hereunder will be paid to the Agent without set-off or counterclaim in United
States dollars, if possible, at the office of the Agent, at 177 Broad Street,
Stamford, Connecticut or as otherwise designated to the Guarantor from time to
time.

          2.8 Subordination of Guarantee.  Notwithstanding any other provision
              --------------------------                                       
of the guarantee contained in this Section 2, the guarantee set forth herein is
subordinate and junior in right of payment to all Senior Indebtedness (as
defined in the Notes) to the extent and as provided in Section 7 of the Notes.

Guarantor, such Guarantor shall take, or shall refrain from taking, as the case

action or to refrain from taking such action by such Guarantor or any of its
Subsidiaries.

          5.2 Maintenance of Insurance.  (a)  Such Grantor will maintain, with
              ------------------------                                        
financially sound and reputable companies, insurance policies (i) insuring the
Inventory and Equipment against loss by fire, explosion, theft and such other
casualties as may be reasonably satisfactory to the Agent and (ii) insuring such
Grantor, the Agent and the Lenders against liability for personal injury and
property damage relating to such Inventory and Equipment, such policies to be in
such form and amounts and having such coverage as may be reasonably satisfactory
to the Agent and the Lenders.

          (b) As soon as practicable following the Closing Date, all such
insurance shall (i) provide that no cancellation, material reduction in amount
or material change in coverage thereof shall be effective until at least 30 days
after receipt by the Agent of written notice thereof, (ii) name the Agent as
insured party or loss payee, (iii) if reasonably requested by the Agent, include
a breach of warranty clause and (iv) be reasonably satisfactory in all other
respects to the Agent.

          (c) The Borrower shall deliver to the Agent and the Lenders a report
of a reputable insurance broker with respect to such insurance during the month

as the Agent may from time to time reasonably request.

          5.3 Payment of Obligations.  Such Grantor will pay and discharge or
              ----------------------                                         
otherwise satisfy at or before maturity or before they become delinquent, as the
case may be, all taxes, assessments and governmental charges or levies imposed
upon the Collateral or in respect of income or profits therefrom, as well as all
claims of any kind (including, without limitation, claims for labor, materials
and supplies) against or with respect to the Collateral, except that no such
charge need be paid if the amount or validity thereof is currently being
contested in good faith by appropriate proceedings, reserves in conformity with
GAAP with respect thereto have been provided on the books of such Grantor and
such proceedings could not reasonably be expected to result in the sale,
forfeiture or loss of any material portion of the Collateral or any interest


                                      12
<PAGE>
 
therein.  Notwithstanding anything to the contrary in the foregoing sentence,
the Borrower shall not be in default under this Section 5.3 unless the aggregate
amount of non-contested Indebtedness or obligations which the Borrower and its
Subsidiaries have so failed to pay, discharge or satisfy before they become
delinquent and which remain delinquent at the time of determination is more than
$50,000 in the aggregate.

              ----------------------------------------------------------------- 
(a)  Such Grantor shall maintain the security interest created by this Agreement
as a perfected security interest having at least the priority described in
Section 4.3 and shall defend such security interest against the claims and
demands of all Persons whomsoever.

          (b) Such Grantor will furnish to the Agent and the Lenders from time
to time statements and schedules further identifying and describing the
Collateral and such other reports in connection with the Collateral as the Agent
may reasonably request, all in reasonable detail.

          (c) At any time and from time to time, upon the written request of the
Agent and at the sole expense of such Grantor, such Grantor will promptly and
duly execute and deliver, and have recorded, such further instruments and
documents and take such further actions as the Agent may reasonably request for
the purpose of obtaining or preserving the full benefits of this Agreement and
of the rights and powers herein granted, including, without limitation, the
filing of any financing or continuation statements under the Uniform Commercial
Code (or other similar laws) in effect in any jurisdiction with respect to the
security interests created hereby.

          5.5 Changes in Locations, Name, etc.  Such Grantor will not, except
              --------------------------------                               
upon 15 days' prior written notice to the Agent and delivery to the Agent of (a)
all additional executed financing statements and other documents reasonably
requested by the Agent to maintain the validity, perfection and priority of the
security interests provided for herein and (b) if applicable, a written
supplement to Schedule 5 showing any additional location at which Inventory or

          (i) permit any of the Inventory or Equipment to be kept at a location
              other than those listed on Schedule 5;
                                         ---------- 

          (ii) change the location of its chief executive office or sole place
               of business from that referred to in Section 4.4; or

          (iii) change its name, identity or corporate structure to such an
                extent that any financing statement filed by the Agent in
                connection with this Agreement would become misleading.

issued in connection with any reorganization), option or rights in respect of
the Capital Stock of any Issuer, whether in addition to, in substitution of, as

and deliver the same forthwith to the Agent in the exact form received, duly
indorsed by such Grantor to the Agent, if required, together with an undated
stock power covering such certificate duly executed in blank by such Grantor and

interest in favor of the Agent, be delivered to the Agent to be held by it
hereunder as additional collateral security for the Obligations.  If any sums of
money or property so paid or distributed in respect of the Pledged Securities
shall be received by such Grantor, such Grantor shall, until such money or

equity securities of any nature of any Issuer, except to the extent such stock
or other equity securities are pledged to the Lenders pursuant hereto, (ii)
sell, assign, transfer, exchange, or otherwise dispose of, or grant any option
with respect to, the Pledged Securities or Proceeds thereof (except pursuant to

Person with respect to, any of the Pledged Securities or Proceeds thereof, or

Agreement or (iv) enter into any agreement or undertaking restricting the right
or ability of such Grantor or the Agent to sell, assign or transfer any of the
Pledged Securities or Proceeds thereof.

occurrence of any of the events described in Section 5.7(a) with respect to the
Pledged Securities issued by it and (iii) the terms of Sections 6.3(c) and 6.7
shall apply to it, mutatis mutandis, with respect to all actions that may be
                   ----------------

              ---------------------                                      
through licensees) will (i) continue to use each material Trademark on each and

<PAGE>
 
the Lenders, shall obtain a perfected security interest in such mark pursuant to
this Agreement, and (v) not (and not permit any licensee or sublicensee thereof
to) do any act or knowingly omit to do any act whereby such Trademark may become
invalidated or impaired in any way.

          (b) Such Grantor (either itself or through licensees) will not do any

abandoned or dedicated to the public.

          (c) Such Grantor (either itself or through licensees) (i) will employ
each material Copyright and (ii) will not (and will not permit any licensee or
sublicensee thereof to) do any act or knowingly omit to do any act whereby any
material portion of the Copyrights may become invalidated or otherwise impaired.
Such Grantor will not (either itself or through licensees) do any act whereby
any material portion of the Copyrights may fall into the public domain.

          (d) Such Grantor (either itself or through licensees) will not do any

development in, any proceeding in the United States Patent and Trademark Office,
the United States Copyright Office or any court or tribunal in any country)
regarding such Grantor's ownership of, or the validity of, any material
Intellectual Property or such Grantor's right to register the same or to own and
maintain the same.

employee, licensee or designee, shall file an application for the registration
of any Intellectual Property with the United States Patent and Trademark Office,
the United States Copyright Office or any similar office or agency in any other
country or any political subdivision thereof, such Grantor shall report such
filing to the Agent within five Business Days after the last day of the fiscal
quarter in which such filing occurs.  Upon request of the Agent, such Grantor
shall execute and deliver, and have recorded, any and all agreements,
instruments, documents, and papers as the Agent may request to evidence the
Agent's and the Lenders' security interest in any Copyright, Patent or Trademark
and the goodwill and general intangibles of such Grantor relating thereto or
represented thereby.

                        SECTION 6. REMEDIAL PROVISIONS

          6.1 Certain Matters Relating to Receivables.  (a)  The Agent shall
              ---------------------------------------                       
have the right to make test verifications of the Receivables in any manner and
through any medium that it reasonably considers advisable, and each Grantor
shall furnish all such assistance and information as the Agent may require in
connection with such test verifications.  At any time and from time to time,
upon the Agent's reasonable request and at the expense of the relevant Grantor,
such Grantor shall cause independent public accountants or others reasonably
satisfactory to the Agent to furnish to the Agent reports showing
reconciliations, aging and test verifications of, and trial balances for, the
Receivables.

          (b) The Agent hereby authorizes each Grantor to collect such Grantor's
Receivables (or enter into arrangements with a third party for such collection),
subject to the Agent's reasonable direction and control and the Agent may
curtail or terminate said authority at any time after the occurrence and during
the continuance of an Event of Default. If required by the Agent at any time
after the occurrence and during the continuance of an Event of Default, any
payments of Receivables, when collected by any Grantor, (i) shall be forthwith
(and, in any event, within two Business Days) deposited by such Grantor in the
exact form received, duly indorsed by such Grantor to the Agent if required, in
a Collateral Account maintained under the sole dominion and control of the
Agent, subject to withdrawal by the Agent for the account of the Lenders only as
provided in Section 6.5, and (ii) until so turned over, shall be held by such
Grantor in trust for the Agent and the Lenders, segregated from other funds of
such Grantor.  Each such deposit of Proceeds of Receivables shall be accompanied
by a report identifying in reasonable detail the nature and source of the
payments included in the deposit.

          (c) At the Agent's request, each Grantor shall deliver to the Agent
all original and other documents evidencing, and relating to, the agreements and

                                      17
<PAGE>
 
transactions which gave rise to the Receivables, including, without limitation,
all original orders, invoices and shipping receipts.

          6.2 Communications with Obligors; Grantors Remain Liable. (a)  The
              ----------------------------------------------------          
Agent in its own name or in the name of others may at any time after the
occurrence and during the continuance of an Event of Default communicate with
obligors under the Receivables to verify with them to the Agent's satisfaction
the existence, amount and terms of any Receivables.

          (b) Upon the request of the Agent at any time after the occurrence and
during the continuance of an Event of Default, each Grantor shall notify
obligors on the Receivables that the Receivables have been assigned to the Agent
for the benefit of the Lenders and that payments in respect thereof shall be
made directly to the Agent.

          (c) Anything herein to the contrary notwithstanding, each Grantor
shall remain liable under each of the Receivables to observe and perform all the
conditions and obligations to be observed and performed by it thereunder, all in
accordance with the terms of any agreement giving rise thereto.  Neither the
Agent nor any Lender shall have any obligation or liability under any Receivable
(or any agreement giving rise thereto) by reason of or arising out of this
Agreement or the receipt by the Agent or any Lender of any payment relating
thereto, nor shall the Agent or any Lender be obligated in any manner to perform
any of the obligations of any Grantor under or pursuant to any Receivable (or
any agreement giving rise thereto), to make any payment, to make any inquiry as
to the nature or the sufficiency of any payment received by it or as to the
sufficiency of any performance by any party thereunder, to present or file any
claim to take any action to enforce any performance or to collect the payment of
any amounts which may have been assigned to it or to which it may be entitled at
any time or times.

          6.3 Pledged Stock.  (a)  Unless an Event of Default shall have
              -------------                                             
occurred and be continuing and the Agent shall have given notice to the relevant
Grantor of the Agent's intent to exercise its corresponding rights pursuant to
Section 6.3(b), each Grantor shall be permitted to receive all cash dividends
paid in respect of the Pledged Stock and all payments made in respect of the
Pledged Notes, in each case paid in the normal course of business of the
relevant Issuer and consistent with past practice, to the extent permitted in
the Note Purchase Agreement, and to exercise all voting and corporate rights
with respect to the Pledged Securities; provided, however, that no vote shall be
                                        --------  -------                       
cast or corporate right exercised or other action taken which, in the Agent's
reasonable judgment, would impair the Collateral or which would be inconsistent
with or result in any violation of any provision of the Note Purchase Agreement,
this Agreement or any other Loan Document.

                                      18
<PAGE>
 
          (b) If an Event of Default shall occur and be continuing and the Agent
shall give notice of its intent to exercise such rights to the relevant Grantor
or Grantors, (i) the Agent shall have the right to receive any and all cash
dividends, payments or other Proceeds paid in respect of the Pledged Securities
and make application thereof to the Obligations in the order set forth in
Section 6.5, and (ii) any or all of the Pledged Securities shall be registered
in the name of the Agent or its nominee, and the Agent or its nominee may
thereafter exercise (x) all voting, corporate and other rights pertaining to
such Pledged Securities at any meeting of shareholders of the relevant Issuer or
Issuers or otherwise and (y) any and all rights of conversion, exchange and
subscription and any other rights, privileges or options pertaining to such
Pledged Securities as if it were the absolute owner thereof (including, without
limitation, the right to exchange at its discretion any and all of the Pledged
Securities upon the merger, consolidation, reorganization, recapitalization or
other fundamental change in the corporate structure of any Issuer, or upon the
exercise by any Grantor or the Agent of any right, privilege or option
pertaining to such Pledged Securities, and in connection therewith, the right to
deposit and deliver any and all of the Pledged Securities with any committee,
depositary, transfer agent, registrar or other designated agency upon such terms
and conditions as the Agent may determine), all without liability except to
account for property actually received by it, but the Agent shall have no duty
to any Grantor to exercise any such right, privilege or option and shall not be
responsible for any failure to do so or delay in so doing.

          (c) Each Grantor hereby authorizes and instructs each Issuer of any
Pledged Securities pledged by such Grantor hereunder to (i) comply with any
instruction received by it from the Agent in writing that (x) states that an
Event of Default has occurred and is continuing and (y) is otherwise in
accordance with the terms of this Agreement, without any other or further
instructions from such Grantor, and each Grantor agrees that each Issuer shall
be fully protected in so complying, and (ii) unless otherwise expressly
permitted hereby, pay any dividends or other payments with respect to the
Pledged Securities directly to the Agent.

          6.4 Proceeds to be Turned Over To Agent.  In addition to the rights of
              -----------------------------------                               
the Agent and the Lenders specified in Section 6.1 with respect to payments of
Receivables, if an Event of Default shall occur and be continuing, all Proceeds
received by any Grantor consisting of cash, checks and other near-cash items
shall be held by such Grantor in trust for the Agent and the Lenders, segregated
from other funds of such Grantor, and shall, forthwith upon receipt by such
Grantor, be turned over to the Agent in the exact form received by such Grantor
(duly indorsed by such Grantor to the Agent, if required).  All Proceeds
received by the Agent hereunder shall be held by the Agent in a Collateral
Account maintained under its sole dominion and control.  All Proceeds while held
by the Agent in a Collateral Account (or by such Grantor in trust for the Agent
and the Lenders) shall continue to be held as collateral security for all the

                                      19
<PAGE>
 
Obligations and shall not constitute payment thereof until applied as provided
in Section 6.5.

          6.5 Application of Proceeds.  At such intervals as may be agreed upon
              -----------------------

            First, to pay incurred and unpaid fees and expenses of the Agent
            -----

- --- ----
and owing and remaining unpaid to the Lenders;

            Third, to the Agent, for application by it towards prepayment of the
            -----                                                               
Obligations, pro rata among the Lenders according to the amounts of the

the same.

          6.6 Code and Other Remedies.  If an Event of Default shall occur and
              -----------------------                                         
be continuing, the Agent, on behalf of the Lenders, may exercise, in addition to
all other rights and remedies granted to them in this Agreement and in any other
instrument or agreement securing, evidencing or relating to the Obligations, all
rights and remedies of a secured party under the New York UCC or any other
applicable law.  Without limiting the generality of the foregoing, the Agent,
without demand of performance or other demand, presentment, protest,
advertisement or notice of any kind (except any notice required by law referred
to below) to or upon any Grantor or any other Person (all and each of which
demands, defenses, advertisements and notices are hereby waived), may in such
circumstances forthwith collect, receive, appropriate and realize upon the
Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give
option or options to purchase, or otherwise dispose of and deliver the
Collateral or any part thereof (or contract to do any of the foregoing), in one
or more parcels at public or private sale or sales, at any exchange, broker's
board or office of the Agent or any Lender or elsewhere upon such terms and
conditions as it may deem advisable and at such prices as it may deem best, for
cash or on credit or for future delivery without assumption of any credit risk.
The Agent or any Lender shall have the right upon any such public sale or sales,
and, to the extent permitted by law, upon any 

                                      20
<PAGE>
 
such private sale or sales, to purchase the whole or any part of the Collateral
so sold, free of any right or equity of redemption in any Grantor, which right
or equity is hereby waived and released. Each Grantor further agrees, at the
Agent's request, to assemble the Collateral and make it available to the Agent
at places which the Agent shall reasonably select, whether at such Grantor's
premises or elsewhere. The Agent shall apply the net proceeds of any action
taken by it pursuant to this Section 6.6, after deducting all reasonable costs
and expenses of every kind incurred in connection therewith or incidental to the
care or safekeeping of any of the Collateral or in any way relating to the
Collateral or the rights of the Agent and the Lenders hereunder, including,
without limitation, reasonable attorneys' fees and disbursements, to the payment
in whole or in part of the Obligations, in such order as the Agent may elect,
and only after such application and after the payment by the Agent of any other
amount required by any provision of law, including, without limitation, Section
9-504(l)(c) of the New York UCC, need the Agent account for the surplus, if any,
to any Grantor. To the extent permitted by applicable law, each Grantor waives
all claims, damages and demands it may acquire against the Agent or any Lender
arising out of the exercise by them of any rights hereunder except any such
claims arising out of the Agent or any Lender's gross negligence or wilful
misconduct. If any notice of a proposed sale or other disposition of Collateral
shall be required by law, such notice shall be deemed reasonable and proper if
given at least 10 days before such sale or other disposition.

          6.7 Registration Rights.  (a)  If the Agent shall  determine to
              -------------------                                        
exercise its right to sell any or all of the Pledged Stock pursuant to Section
6.6, and if in the opinion of the Agent it is necessary or advisable to have the
Pledged Stock, or that portion thereof to be sold, registered under the
provisions of the Securities Act or other similar law of any jurisdiction in
which an Issuer is located, the relevant Grantor will cause the Issuer thereof
to (i) execute and deliver, and cause the directors and officers of such Issuer
to execute and deliver, all such instruments and documents, and do or cause to
be done all such other acts as may be, in the reasonable opinion of the Agent,
necessary or advisable to register the Pledged Stock, or that portion thereof to
be sold, under the provisions of the Securities Act or other similar law of any
jurisdiction in which an Issuer is located, (ii) use its best efforts to cause
the registration statement relating thereto to become effective and to remain
effective for a period of one year from the date of the first public offering of
the Pledged Stock, or that portion thereof to be sold, and (iii) make all
amendments thereto and/or to the related prospectus which, in the opinion of the
Agent, are necessary or advisable, all in conformity with the requirements of
the Securities Act and the rules and regulations of the Securities and Exchange
Commission or other similar law of any jurisdiction in which an Issuer is
located, applicable thereto.  Each Grantor agrees to cause such Issuer to comply
with the provisions of the securities or "Blue Sky" laws of any and all
jurisdictions which the Agent shall designate and to make available to its
security holders, as soon as practicable, an earnings statement (which need not
be audited) which will in the case of 

                                      21

<PAGE>
 
United States resident Issuers, satisfy the provisions of Section 11(a) of the
Securities Act.

          (b) Each Grantor recognizes that the Agent may be unable to effect a
public sale of any or all the Pledged Stock, by reason of certain prohibitions
contained in the Securities Act and applicable state securities laws or
otherwise, and may be compelled to resort to one or more private sales thereof
to a restricted group of purchasers which will be obliged to agree, among other
things, to acquire such securities for their own account for investment and not
with a view to the distribution or resale thereof.  Each Grantor acknowledges
and agrees that any such private sale may result in prices and other terms less
favorable than if such sale were a public sale and, notwithstanding such
circumstances, agrees that any such private sale shall be deemed to have been
made in a commercially reasonable manner.  The Agent shall be under no
obligation to delay a sale of any of the Pledged Stock for the period of time
necessary to permit the Issuer thereof to register such securities for public
sale under the Securities Act, or under applicable state securities laws, even
if such Issuer would agree to do so.

          (c) Each Grantor agrees to use its best efforts to do or cause to be
done all such other acts as may be necessary to make such sale or sales of all
or any portion of the Pledged Stock pursuant to this Section 6.7 valid and
binding and in compliance with any and all other applicable Requirements of Law.
Each Grantor further agrees that a breach of any of the covenants contained in
this Section 6.7 will cause irreparable injury to the Agent and the Lenders,
that the Agent and the Lenders have no adequate remedy at law in respect of such
breach and, as a consequence, that each and every covenant contained in this
Section 6.7 shall be specifically enforceable against such Grantor, and such
Grantor hereby waives and agrees not to assert any defenses against an action
for specific performance of such covenants except for a defense that no Event of
Default has occurred under the Note Purchase Agreement.

          6.8 Waiver; Deficiency.  Each Grantor waives and agrees not to assert
              ------------------                                               
any rights or privileges which it may acquire under Section 9-112 of the New
York UCC.  Each Grantor shall remain liable for any deficiency if the proceeds
of any sale or other disposition of the Collateral are insufficient to pay its
Obligations and the fees and disbursements of any attorneys employed by the
Agent or any Lender to collect such deficiency.


                             SECTION 7. THE AGENT

          7.1 Agent's Appointment as Attorney-in-Fact, etc. (a) Each Grantor
              ---------------------------------------------                 
hereby irrevocably constitutes and appoints the Agent and any officer or agent
thereof, with full power of substitution, as its true and lawful attorney-in-
fact with full 

                                      22
<PAGE>
 
irrevocable power and authority in the place and stead of such Grantor and in
the name of such Grantor or in its own name, for the purpose of carrying out the
terms of this Agreement, to take any and all appropriate action and to execute
any and all documents and instruments which may be necessary or desirable to
accomplish the purposes of this Agreement, and, without limiting the generality
of the foregoing, each Grantor hereby gives the Agent the power and right, on
behalf of such Grantor, without notice to or assent by such Grantor, to do any
or all of the following:

              (i)  in the name of such Grantor or its own name, or otherwise,
     take possession of and indorse and collect any checks, drafts, notes,
     acceptances or other instruments for the payment of moneys due under any
     Receivable or with respect to any other Collateral and file any claim or
     take any other action or proceeding in any court of law or equity or
     otherwise deemed appropriate by the Agent for the purpose of collecting any
     and all such moneys due under any Receivable or with respect to any other
     Collateral whenever payable;

              (ii) in the case of any Intellectual Property, execute and
     deliver, and have recorded, any and all agreements, instruments, documents
     and papers as the Agent may request to evidence the Agent's and the
     Lenders' security interest in such Intellectual Property and the goodwill
     and general intangibles of such Grantor relating thereto or represented
     thereby;

              (iii) pay or discharge taxes and Liens levied or placed on or
     threatened against the Collateral, effect any repairs or any insurance
     called for by the terms of this Agreement and pay all or any part of the
     premiums therefor and the costs thereof;

              (iv) execute, in connection with any sale provided for in Section
     6.6 or 6.7, any endorsements, assignments or other instruments of
     conveyance or transfer with respect to the Collateral; and

              (v)  (1) direct any party liable for any payment under any of the
     Collateral to make payment of any and all moneys due or to become due
     thereunder directly to the Agent or as the Agent shall direct; (2) ask or
     demand for, collect, and receive payment of and receipt for, any and all
     moneys, claims and other amounts due or to become due at any time in
     respect of or arising out of any Collateral; (3) sign and indorse any
     invoices, freight or express bills, bills of lading, storage or warehouse
     receipts, drafts against debtors, assignments, verifications, notices and
     other documents in connection with any of the Collateral; (4) commence and
     prosecute any suits, actions or proceedings at law or in equity in any
     court of competent jurisdiction to collect the Collateral or any portion
     thereof and to enforce any other right in respect of any Collateral; (5)
     defend any suit, action or proceeding brought against such 

                                      23
<PAGE>
 
     Grantor with respect to any Collateral; (6) settle, compromise or adjust
     any such suit, action or proceeding and, in connection therewith, give such
     discharges or releases as the Agent may deem appropriate; (7) assign any
     Copyright, Patent or Trademark (along with the goodwill of the business to
     which any such Copyright, Patent or Trademark pertains), throughout the
     world for such term or terms, on such conditions, and in such manner, as
     the Agent shall in its sole discretion determine; and (8) generally, sell,
     transfer, pledge and make any agreement with respect to or otherwise deal
     with any of the Collateral as fully and completely as though the Agent were
     the absolute owner thereof for all purposes, and do, at the Agent's option
     and such Grantor's expense, at any time, or from time to time, all acts and
     things which the Agent deems necessary to protect, preserve or realize upon
     the Collateral and the Agent's and the Lenders' security interests therein
     and to effect the intent of this Agreement, all as fully and effectively as
     such Grantor might do.

     Anything in this Section 7.1(a) to the contrary notwithstanding, the Agent
agrees that it will not exercise any rights under the power of attorney provided
for in this Section 7.1(a) unless an Event of Default shall have occurred and be
continuing.

          (b) If any Grantor fails to perform or comply with any of its
agreements contained herein, the Agent, at its option, but without any
obligation so to do, may perform or comply, or otherwise cause performance or
compliance, with such agreement.

          (c) The reasonable expenses of the Agent incurred in connection with
actions undertaken as provided in this Section 7.1, together with interest
thereon at a rate per annum equal to the rate per annum at which interest would
then be payable on past due payments of principal under the Notes from the date
of payment by the Agent to the date reimbursed by the relevant Grantor, shall be
payable by such Grantor to the Agent on demand.

          (d) Each Grantor hereby ratifies all that said attorneys shall
lawfully do or cause to be done by virtue hereof.  All powers, authorizations
and agencies contained in this Agreement are coupled with an interest and are
irrevocable until this Agreement is terminated and the security interests
created hereby are released pursuant to Section 8.16(a) hereof.

          7.2 Duty of Agent.  The Agent's sole duty with respect to the custody,
              -------------                                                     
safekeeping and physical preservation of the Collateral in its possession, under
Section 9-207 of the New York UCC or otherwise, shall be to deal with it in the
same manner as the Agent deals with similar property for its own account.
Neither the Agent, any Lender nor any of their respective officers, directors,
employees or agents shall be liable for failure to demand, collect or realize
upon any of the Collateral or for 

                                      24
<PAGE>
 
any delay in doing so or shall be under any obligation to sell or otherwise
dispose of any Collateral upon the request of any Grantor or any other Person or
to take any other action whatsoever with regard to the Collateral or any part
thereof. The powers conferred on the Agent and the Lenders hereunder are solely
to protect the Agent's and the Lenders' interests in the Collateral and shall
not impose any duty upon the Agent or any Lender to exercise any such powers.
The Agent and the Lenders shall be accountable only for amounts that they
actually receive as a result of the exercise of such powers, and neither they
nor any of their officers, directors, employees or agents shall be responsible
to any Grantor for any act or failure to act hereunder, except for their own
gross negligence or willful misconduct.

          7.3 Execution of Financing Statements.  Pursuant to Section 9-402 of
              ---------------------------------                               
the New York UCC and any other applicable law, each Grantor authorizes the Agent
to file or record financing statements and other filing or recording documents
or instruments with respect to the Collateral without the signature of such
Grantor in such form and in such offices as the Agent reasonably determines
appropriate to perfect the security interests of the Agent under this Agreement.
A photographic or other reproduction of this Agreement shall be sufficient as a
financing statement or other filing or recording document or instrument for
filing or recording in any jurisdiction.

          7.4 Authority of Agent.  Each Grantor acknowledges that the rights and
              ------------------                                                
responsibilities of the Agent under this Agreement with respect to any action
taken by the Agent or the exercise or non-exercise by the Agent of any option,
voting right, request, judgment or other right or remedy provided for herein or
resulting or arising out of this Agreement shall, as between the Agent and the
Lenders, be governed by such agreements with respect thereto as may exist from
time to time among them, but, as between the Agent and the Grantors, the Agent
shall be conclusively presumed to be acting as agent for the Lenders with full
and valid authority so to act or refrain from acting, and no Grantor shall be
under any obligation, or entitlement, to make any inquiry respecting such
authority.


                           SECTION 8. MISCELLANEOUS

          8.1 Amendments in Writing.  None of the terms or provisions of this
              ---------------------                                          
Agreement may be waived, amended, supplemented or otherwise modified except in
accordance with Section 11.6 of the Note Purchase Agreement.

          8.2 Notices.  All notices, requests and demands to or upon the Agent
              -------                                                         
or any Grantor hereunder shall be effected in the manner provided for in Section
11.3 of the Subordinated Note and Stock Purchase Agreement; provided that any
                                                            --------         
such notice, request or demand to or upon any Guarantor shall be addressed to
such Guarantor at its notice address set forth on Schedule 1.
                                                  ---------- 

                                      25
<PAGE>
 
          8.3 No Waiver by Course of Conduct; Cumulative Remedies. Neither the
              ---------------------------------------------------             
Agent nor any Lender shall by any act (except by a written instrument pursuant
to Section 8.1), delay, indulgence, omission or otherwise be deemed to have
waived any right or remedy hereunder or to have acquiesced in any Default or
Event of Default.  No failure to exercise, nor any delay in exercising, on the
part of the Agent or any Lender, any right, power or privilege hereunder shall
operate as a waiver thereof.  No single or partial exercise of any right, power
or privilege hereunder shall preclude any other or further exercise thereof or
the exercise of any other right, power or privilege.  A waiver by the Agent or
any Lender of any right or remedy hereunder on any one occasion shall not be
construed as a bar to any right or remedy which the Agent or such Lender would
otherwise have on any future occasion.  The rights and remedies herein provided
are cumulative, may be exercised singly or concurrently and are not exclusive of
any other rights or remedies provided by law.

          8.4 Enforcement Expenses; Indemnification.  (a) Each Guarantor agrees

expenses incurred in collecting against such Guarantor under the guarantee
contained in Section 2 or otherwise enforcing or preserving any rights under
this Agreement and the other Loan Documents to which such Guarantor is a party,
including, without limitation, the reasonable fees and disbursements of counsel
to each Lender and of counsel to the Agent.

          (b) Each Guarantor agrees to pay, and to save the Agent and the
Lenders harmless from, any and all liabilities with respect to, or resulting
from any delay in paying, any and all stamp, excise, sales or other taxes which
may be payable or determined to be payable with respect to any of the Collateral
or in connection with any of the transactions contemplated by this Agreement.

          (c) Each Guarantor agrees to pay, and to save the Agent and the
Lenders harmless from, any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever with respect to the execution, delivery, enforcement,
performance and administration of this Agreement to the extent the Borrower
would be required to do so pursuant to Article 7 of the Note Purchase Agreement.

          (d) The agreements in this Section 8.4 shall survive repayment of the
Obligations and all other amounts payable under the Note Purchase Agreement and
the other Loan Documents.

          8.5 Successors and Assigns.  This Agreement shall be binding upon the
              ----------------------                                           
successors and assigns of each Grantor and shall inure to the benefit of the
Agent and the Lenders and their successors and assigns; provided that no Grantor
                                                        --------

without the prior written consent of the Agent.

          8.6 Counterparts.  This Agreement may be executed by one or more of
              ------------                                                   
the parties to this Agreement on any number of separate counterparts (including
by telecopy), and all of said counterparts taken together shall be deemed to
constitute one and the same instrument.

          8.7 Severability.  Any provision of this Agreement which is prohibited
              ------------

ineffective to the extent of such prohibition or unenforceability without

          (c) no joint venture is created hereby or by the other Loan Documents

          8.15 Releases. (a) At such time as the Obligations shall have been

Fully Satisfied, the Collateral shall be released from the Liens created hereby,
and this Agreement and all obligations (other than those expressly stated to
survive such termination) of the Agent and each Grantor hereunder shall
terminate, all without delivery of any instrument or performance of any act by
any party, and all rights to the Collateral shall revert to the Grantors.  At
the request and sole expense of any Grantor following any such termination, the
Agent shall deliver to such Grantor any Collateral held by the Agent hereunder,
and execute and deliver to such Grantor such documents as such Grantor shall
reasonably request to evidence such termination.

Agreement, then the Agent, at the request and sole expense of such Grantor,

Borrower shall have delivered to the Agent, at least ten Business Days prior to

   is now or may at any time and from time to time hereafter be obligated to pay
   to the Secured Parties or any one or more of them under any of the Documents
   to which the Pledgors are now or may at any time become a party, if and when
   such amounts become due and payable (such agreement and covenant the
   "Covenant Obligation"). ----

<PAGE>
 
                                                                             -6-

   each of the Pledgors' Covenant Obligation consists of the obligations and
   liabilities of each of the Pledgors to J.H. Whitney & Co., as Security Agent,
   separate and independent from and without prejudice to the other Guarantor
   Obligations which each of the Pledgors has or may have at any time to the
   Lenders (including Whitney Subordinated Debt Fund, L.P.) and the Security
   Agent under this Agreement or any of the other Documents or otherwise, and
   (ii) each of the Pledgors' Covenant Obligation represents the Security

                       -----------------                                     
   Covenant Obligation, separate and independent from any claims of the Secured
   Parties on each of the Pledgors; provided that the total liability of each of
   the Pledgors under its Covenant Obligation and under its Guarantor Obligation
   shall never exceed the total liability of the Pledgors' liability under the
   Guarantor Obligations and that the total liability of the Pledgors under
   their respective Covenant Obligations shall be decreased from time to time by
   the amount that any of the Pledgors shall have permanently paid either toward
   its Guarantor Obligation or its Covenant to Pay. ---------------------------

c. If, after foreclosure of all collateral in which a security interest or lien
   has been granted or will be granted by each of the Pledgors, the proceeds are
   not sufficient to satisfy and discharge each of the Pledgors' Covenant
   Obligation, the remainder of such Covenant Obligation shall then cease to
   exist, but without prejudice to any other Guarantor Obligations which any of
   the Pledgors may have and without prejudice to any other remedies which the
   Secured Parties may have under any of the Documents. ------------------------

d. Without limitation of the foregoing provisions of this Section 1, nothing
   contained in this Section shall in any way negate or affect any Guarantor
   Obligations other than the Covenant Obligation which each of the Pledgors has
   or at any time may have under the Documents or otherwise to the Lenders and
   the Security Agent. ---------------------------------------------------------

                   ------------------------------- 
below, at any time the Designated Holders holding at least 25% of the
Registrable Securities held by all of the Designated Holders (the "INITIATING
                                                                   ----------
HOLDERS") may request in writing the registration of Registrable Securities
- -------
under the Act, and under

                                      -3-
<PAGE>
 
the securities or blue sky laws of any jurisdiction designated by such holder or
holders (each such registration under this Section 3(a) that satisfies the
requirements set forth in Section 3(b) is referred to herein as a "DEMAND
                                                                   ------
REGISTRATION").  Notwithstanding the foregoing, in no event shall the Company be
- ------------                                                                    
required to effect more than three Demand Registrations.  Two or more
registrations filed in response to one demand shall be counted as one
registration statement.  Each request for a Demand Registration by the
Initiating Holders in respect thereof shall specify the amount of the
Registrable Securities proposed to be sold, the intended method of disposition
thereof and the jurisdictions in which registration is desired.  Upon a request
for a Demand Registration, the Company shall promptly take such steps as are
necessary or appropriate to prepare for the registration of the Registrable
Securities to be registered. Within fifteen (15) days after the receipt of such
request, the Company shall give written notice thereof to all other Designated
Holders and include in such registration all Registrable Securities held by a
Designated Holder from whom the Company has received a written request for
inclusion therein at least ten (10) days prior to the filing of the registration
statement.  Each such request will also specify the number of Registrable
Securities to be registered, the intended method of disposition thereof and the
jurisdictions in which registration is desired.  Subject to Section 3(d), the
Company shall be entitled to include in any registration statement and offering
made pursuant to a Demand Registration, authorized but unissued shares of Common
Stock, shares of Common Stock held by the Company as treasury shares or shares
of Common Stock held by Stockholders other than the Holders; provided, that such
inclusion shall be permitted only to the extent that it is pursuant to and
subject to the terms of the underwriting agreement or arrangements, if any,
entered into by the Initiating Holders exercising the Demand Registration
rights.

          (b) Effective Demand Registration.  The Company shall use its best
              -----------------------------                                 
efforts to cause any such Demand Registration to become effective not later than
ninety (90) days after it receives a request under Section 3(a).  A registration
requested pursuant to Section 3(a) hereof shall not count as one of the three
demands to which the Designated Holders are entitled thereunder unless such
registration statement is declared effective and remains effective for at least
ninety (90) days.

          (c) Expenses.  In any registration initiated as a Demand Registration,
              --------                                                          
the Company shall pay all Registration Expenses in connection therewith, whether
or not such requested Demand Registration becomes effective.

          (d) Underwriting Procedures.  If the Initiating Holders holding a
              -----------------------                                      
majority of the Registrable Securities held by all Initiating Holders to which
the requested Demand Registration relates so elect, the offering of such
Registrable Securities pursuant to such requested Demand Registration shall be
in the form of a firm commitment underwritten offering and the managing
underwriter or underwriters selected for such offering shall be the Approved
Underwriter selected in accordance with Section 3(e).  In such event, if the
Approved Underwriter advises the Company in writing that, in its opinion, the
aggregate amount of such Registrable Securities requested to be included in such
offering (including those securities requested by the Company to be included in
such registration) is sufficiently large to have an adverse effect on the
success of such offering, then the Company shall include in such registration 

                                      -4-
<PAGE>
 
only the aggregate amount of Registrable Securities that in the opinion of the
Approved Underwriter may be sold without any such effect on the success of such
offering (the "APPROVED UNDERWRITER AMOUNT"), and (i) each Designated Holder
               ---------------------------                                  
shall be entitled to have included in such registration Registrable Securities
equal to its pro rata portion of the Approved Underwriter Amount, as based on
the amounts of Registrable Securities sought to be registered by the Designated
Holders in their requests for participation in the requested Demand Registration
and (ii) to the extent that the number of Registrable Securities to be included
by the Designated Holders is less than the Approved Underwriter Amount,
securities that the Company proposes to register shall also be included.

       If, as a result of the proration provision of this Section 3(d), any
Designated Holder shall not be entitled to include all Registrable Securities in
a registration that such Designated Holder has requested to be included, such
Designated Holder may elect to withdraw his request to include Registrable
Securities in such registration or may reduce the number requested to be
included; provided, however, that (x) such request must be made in writing prior
to the earlier of the execution of the underwriting agreement or the execution
of the custody agreement with respect to such registration and (y) such
withdrawal or reduction shall be irrevocable.

          (e) Selection of Underwriters.  If any requested Demand Registration
              -------------------------                                       
is in the form of an underwritten offering, the Initiating Holders holding a
majority of the Registrable Securities held by all Initiating Holders to be
included in the requested Demand Registration shall select and obtain an
investment banking firm of national reputation to act as the managing
underwriter of the offering (the "APPROVED UNDERWRITER"); provided, that such
                                  --------------------                       
underwriter shall be reasonably satisfactory to the Company.

          (f) Limitations on Demand Registrations.  The Demand Registration
              -----------------------------------                          
rights granted to the Holders in Section 3(a) are subject to the following
limitations: (i) each registration in respect of a Demand Registration must
include Registrable Securities having an aggregate market value of at least
$5,000,000.00, which market value shall be determined by multiplying the number
of Registrable Securities to be included in the Demand Registration by the
proposed per share offering price (provided that the limitation set forth in
this clause (i) shall not be in effect at any time the Holders' Registrable
Securities are not able to be sold under Rule 144 under the Act because of the
Company's failure to comply with the information requirements thereunder, unless
at such time, the Company's outside counsel (which shall be reasonably
acceptable to the Holders requesting such registration) delivers a written
opinion of counsel to such Holders to the effect that such Holders' Registrable
Securities may be publicly offered and sold without registration under the Act);
(ii) the Company shall not be required to cause a registration pursuant to
Section 3(a) to be declared effective within a period of 150 days after the
effective date of any registration statement of the Company effected in
connection with a Demand Registration; and (iii) if the Board of Directors of
the Company, in its good faith judgment, determines that any registration of
Registrable Securities should not be made or continued because it would
materially interfere with any material financing, acquisition, corporate
reorganization or merger or other

transaction involving the Company or any of its subsidiaries (a "VALID BUSINESS
                                                                 -------------- 
REASON"), the Company may (x) postpone filing a registration statement relating
- ------
to a Demand Registration until such Valid Business Reason no longer exists, but
in no event for more than ninety (90) days, and,(y) in case a registration
statement has been filed relating to a Demand Registration, if the Valid
Business Reason has not resulted from actions taken by the Company, the Company,
upon the approval of a majority of the Company's Board of Directors, such
majority to include at least one director affiliated with WSDF, may cause such
registration statement to be withdrawn and its effectiveness terminated or may
postpone amending or supplementing such registration statement; the Company
shall give written notice of its determination to postpone or withdraw a
registration statement and of the fact that the Valid Business Reason for such
postponement or withdrawal no longer exists, in each case, promptly after the
occurrence thereof. Notwithstanding anything to the contrary contained herein,
the Company may not postpone or withdraw a filing under Section 3(f)(iii) hereof
more than once in any twelve-month period.

          Each Holder of Registrable Securities agrees that, upon receipt of any
notice from the Company that the Company has determined to withdraw any
registration statement pursuant to clause (iii) above, such Holder will
discontinue its disposition of Registrable Securities pursuant to such
registration statement and, if so directed by the Company, will deliver to the
Company (at the Company's expenses) all copies, other than permanent file
copies, then in such Holder's possession, of the prospectus covering such
Registrable Securities that was in effect at the time of receipt of such notice.
If the Company shall give any notice of postponement or withdrawal of a
registration statement, the Company shall, at such time as the Valid Business
Reason that caused such postponement or withdrawal no longer exists (but in no
event no later than ninety (90) days after the date of the postponement), use
its best efforts to promptly effect the registration under the Act of the
Registrable Securities covered by the postponed or withdrawn registration
statement in accordance with this Section 3 (unless the Holder(s) delivering the
Demand Registration request shall have withdrawn such request, in which case the
Company shall not be considered to have effected an effective registration for
the purposes of this Agreement), and such registration shall not be postponed or
withdrawn pursuant to clause (iii) above.

          4.   Piggy-Back Registration.
               ----------------------- 

               (a) Piggy-Back Rights.  If the Company proposes to file a 
                   -----------------
registration statement under the Act with respect to an offering by the Company
for its own account of any class of security (other than a registration
statement on Form S-4 or S-8 (or any successor form thereto)) under the Act,
then the Company shall give written notice of such proposed filing to each of
the Holders at least twenty (20) days before the anticipated filing date, and
such notice shall describe in detail the proposed registration and distribution
(including those jurisdictions where registration under the securities or blue
sky laws is intended) and offer such Holders the opportunity to register the
number of Registrable Securities as each such Holder may request. The Company
shall use its best efforts (within ten (10) days of the notice provided for in
the preceding sentence) to permit the Holders who have requested to participate
in the registration for such offering to include such Registrable Securities in
such offering on

                                      -6-
<PAGE>
 
the same terms and conditions as the securities of the Company included therein.
Notwithstanding the foregoing, if such registration involves an underwritten
offering and the managing underwriters or underwriters (the "COMPANY
                                                             -------    
UNDERWRITER") shall advise the Holders of Registrable Securities in writing
- -----------
that, in its opinion, the total amount of securities requested to be included in
such offering (the "TOTAL SECURITIES") is sufficiently large so as to have an
                    ----------------     
adverse effect on the success of the distribution of the Total Securities, then
the Company shall include in such registration, to the extent of the number of
Registrable Securities which the Company is so advised can be sold in (or during
the time of) such offering, first, all Common Stock or securities convertible
                            -----   
into, or exchangeable or exercisable for, Common Stock that the Company proposed
to register for its own account, second, all securities proposed to be
                                 ------
registered by all Designated Holders and Other Investors, pro rata among such
Designated Holders and Other Investors, and third, all other securities proposed
                                            ----- 
to be registered.

          (b) Priority of Registrations.  Subject to the provisions of Section
              -------------------------                                       
3(f)(iii), if the Company proposes to register securities pursuant to Section
4(a) hereof on the same day that the Designated Holders request a registration
pursuant to Section 3(a) hereof, then the Demand Registration requested pursuant
to Section 3(a) hereof shall be given priority.

          (c) Expenses.  The Company shall bear all Registration Expenses in
              --------                                                      
connection with any registration pursuant to this Section 4.

          (d) Conditions and Limitations on Piggyback Registrations. If, at any
              -----------------------------------------------------            
time after giving written notice of its intention to register any securities and
prior to the effective date of the registration statement filed in connection
with such registration, the Company shall determine for any reason not to
register or to delay registration of such securities, the Company may, at its
election, give written notice of such determination to all Holders of record of
Registrable Securities and (i) in the case of a determination not to register,
shall be relieved of its obligation to register the Registrable Securities in
connection with such abandoned registration, without prejudice, however, to the
rights of Holders under Section 3, and (ii) in the case of a determination to
delay the registration of its securities, shall be permitted to delay the
registration of such Registrable Securities for the same period as the delay in
registering such other equity securities.

          Any Holder shall have the right to withdraw its request for inclusion
of its Registrable Securities in any registration statement pursuant to this
Section 4 by giving written notice to the Company of its request to withdraw;
provided, however, that (i) such request must be made in writing prior to the
earlier of the execution of the underwriting agreement or the execution of the
custody agreement with respect to such registration and (ii) such withdrawal
shall be irrevocable and, after making such withdrawal, a Holder shall no longer
have any right to include Registrable Securities in the registration as to which
such withdrawal was made.

           5.  Holdback Agreements.
               ------------------- 

               (a) Restrictions on Public Sale by Holders.  To the extent not
                   --------------------------------------                    
inconsistent with applicable law, each Holder agrees not to effect any public
sale or distribution of any Registrable Securities being registered or of any
securities convertible into or exchangeable or exercisable for such Registrable
Securities, including a sale pursuant to Rule 144 under the Act, during the
ninety (90) day period beginning on the effective date of such Demand
Registration or Piggy-Back Registration or other underwritten offering (except
as part of such registration), if and to the extent requested by any other
Holder, in the case of a non-underwritten public offering, or if and to the
extent requested by the Company Underwriter, in the case of an underwritten
public offering.

               (b) Restrictions on Public Sale by the Company.  The Company 
                   ------------------------------------------
agrees not to effect any public sale or distribution of any of its securities
for its own account (except pursuant to registrations on Form S-4 or S-8 (or any
successor form thereto) under the Act) during the ninety (90) day period
beginning on the effective date of any registration statement in which the
Holders are participating.

           6.  Registration Procedures.
               ----------------------- 

               (a) Obligations of the Company.  Whenever registration of 
                   --------------------------  
Registrable Securities has been requested pursuant to Section 3 or 4 of this
Agreement, the Company shall use its best efforts to effect the registration and
sale of such Registrable Securities in accordance with the intended method of
distribution thereof as quickly as practicable, and in connection with any such
request, the Company shall, as expeditiously as possible:

                   (i)     prepare and file with the SEC (in any event not later
than sixty (60) Business Days after receipt of a request to file a registration
statement with respect to Registrable Securities) a registration statement on
any form on which registration is requested for which the Company then
qualifies, which counsel for the Company and Holders' Counsel shall deem
appropriate and which shall be available for the sale of such Registrable
Securities in accordance with the intended method of distribution thereof, and
use its best efforts to cause such registration statement to become effective;
provided, however, that before filing a registration statement or prospectus or
- --------  -------                                                              
any amendments or supplements thereto, the Company shall (A) provide Holders'
Counsel with an adequate and appropriate opportunity to participate in the
preparation of such registration statement and each prospectus included therein
(and each amendment or supplement thereto) to be filed with the SEC, which
documents shall be subject to the review of Holders' Counsel, and (B) notify
Holders' Counsel and each seller of Registrable Securities pursuant to such
registration statement of any stop order issued or threatened by the SEC and
take all reasonable action required to prevent the entry of such stop order or
to remove it if entered;

                   (ii)    prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in 
connection  

                                      -8-
<PAGE>
 
therewith as may be necessary to keep such registration statement effective and
to comply with the provisions of the Act with respect to the disposition of all
Registrable Securities covered by such registration statement until the earlier
of (a) such time as all of such Registrable Securities and other securities have
been disposed of in accordance with the intended methods of disposition by the
sellers thereof set forth in such registration statement and (b) 180 days after
the effective date of such registration statement, except with respect to any
such registration statement filed pursuant to Rule 415 (or any successor Rule)
under the Act if the Company is eligible to file a registration statement on
Form S-3, in which case such period shall be two (2) years;

                   (iii)   as soon as reasonably possible, furnish to each
seller of Registrable Securities, prior to filing a registration statement,
copies of such registration statement as it is proposed to be filed, and
thereafter such number of copies of such registration statement, each amendment
and supplement thereto (in each case including all exhibits thereto), the
prospectus included in such registration statement (including each preliminary
prospectus) and such other documents as each such seller may reasonably request
in order to facilitate the disposition of the Registrable Securities owned by
such seller;

                   (iv)    use its best efforts to register or qualify such
Registrable Securities under such other securities or blue sky laws of such
jurisdictions as any seller of Registrable Securities may request, and to
continue such qualification in effect in each such jurisdiction for as long as
is permissible pursuant to the laws of such jurisdiction, or for as long as any
such seller requests or until all of such Registrable Securities are sold,
whichever is shortest, and do any and all other acts and things which may be
reasonably necessary or advisable to enable any such seller to consummate the
disposition in such jurisdictions of the Registrable Securities owned by such
seller; provided, however, that the Company shall not be required to (A) qualify
        --------  -------                                                       
generally to do business in any jurisdiction where it would not otherwise be
required to qualify but for this Section 6(a)(iv), (B) subject itself to
taxation in any such jurisdiction or (C) consent to general service of process
in any such jurisdiction;

                   (v)     use its best efforts to obtain all other approvals,
covenants, exemptions or authorizations from such governmental agencies or
authorities as may be necessary to enable the sellers of such Registrable
Securities to consummate the disposition of such Registrable Securities;

                   (vi)    notify each seller of Registrable Securities at
any time when a prospectus relating thereto is required to be delivered under
the Act, upon discovery that, or upon the happening of any event as a result of
which, the prospectus included in such registration statement contains an untrue
statement of a material fact or omits to state any material fact required to be
stated therein or necessary to make the statements therein not misleading in
light of the circumstances under which they were made, and the Company shall
promptly prepare a supplement or amendment to such prospectus and furnish to
each such seller a reasonable number of copies of a supplement to or amendment
of such prospectus as may be necessary so that, after delivery to the purchasers
of such Registrable Securities, such prospectus

                                      -9-
<PAGE>
 
shall not contain an untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading in light of the circumstances under which they were made;

                   (vii)   enter into and perform customary agreements
(including an underwriting agreement in customary form with the Approved
Underwriter or Company Underwriter, if any, selected as provided in Section 3 or
4; provided, that the underwriting agreement, if any, shall be reasonably
satisfactory in form and substance to the Company) and take such other actions
as are reasonably required in order to expedite or facilitate the disposition of
such Registrable Securities;

the Company and any subsidiaries thereof as may be in existence at such time
(collectively, the "RECORDS") as shall be reasonably necessary to enable them to
                    ------- 
exercise their due diligence responsibility, and cause the Company's and any
subsidiaries' officers, directors and employees, and the independent public
accountants of the Company, to supply all information reasonably requested by
any such Inspector in connection with such registration statement; provided,
that such Inspector agrees to keep all such information confidential.

                   (ix)    obtain a "cold comfort" letter from the Company's
independent public accountants in customary form and covering such matters of
the type customarily covered by "cold comfort" letters, as Holders' Counsel or
the managing underwriter reasonably request;

                   (x)     furnish, at the request of any seller of Registrable
Securities on the date such securities are delivered to the underwriters for
sale pursuant to such registration or, if such securities are not being sold
through underwriters, on the date the registration statement with respect to
such securities becomes effective, an opinion, dated such date, of counsel
representing the Company for the purposes of such registration, addressed to the
underwriters, if any, and to the seller making such request, covering such legal
matters with respect to the registration in respect of which such opinion is
being given as such seller may reasonably request and as are customarily

then

                                      -10-
<PAGE>
 
listed (if any) if the listing of such Registrable Securities is then permitted
under the rules of such exchange or, if no similar securities are then so
listed, cause all such Registrable Securities to be listed on an exchange on
which the Initiating Holders request that such Registrable Securities be listed,
subject to the satisfaction of the applicable listing requirements of each such
exchange;

                   (xiii)  keep each seller of Registrable Securities advised in

disbursements and other charges of counsel) or other liabilities resulting from
or arising out of or based upon any untrue, or alleged untrue, statement of a
material fact contained in any registration statement, prospectus or preliminary
prospectus or notification or offering circular (as amended or supplemented if
the Company shall have furnished any amendments or supplements thereto) or
arising out of or based upon any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements

agrees to indemnify and hold harmless the Company, any underwriter retained by
the Company and their respective directors, officers, employees and each Person
who controls (within the meaning of the Act and the Exchange Act) the Company or
such underwriter to the same extent as the foregoing indemnity from the Company
to the Holders (subject to the proviso to this sentence and applicable law), but
only with respect to any such information furnished in writing by or on behalf
of such Holder expressly for use therein; provided, however, that the liability
                                          --------  -------

any action, suit, proceeding or investigation or threat thereof made in writing
for which the Indemnified Party intends to claim indemnification or contribution
pursuant to this Agreement; provided, that, the failure so to notify the
                            --------  ----                              
Indemnifying Party shall not relieve the Indemnifying Party of any liability
that it may have to the Indemnified Party hereunder.  If notice of commencement
of any such action is given to the Indemnifying Party as above provided, the
Indemnifying Party shall be entitled to participate in and, to the extent it may
wish, jointly with any other Indemnifying Party similarly notified, to assume
the defense of such action at its own expense, with counsel chosen by it and
satisfactory to such Indemnified Party.  The Indemnified Party shall have the
right to employ separate counsel in any such action and participate in the
defense thereof, but the fees and expenses of such counsel (other than
reasonable costs of investigation) shall be paid by the Indemnified Party unless
(i) the Indemnifying Party agrees to pay the same, (ii) the Indemnifying Party
fails to assume the defense of such action with counsel satisfactory to the
Indemnified Party in its reasonable judgment, (iii) the named parties to any
such action (including any impleaded parties) have been advised by such counsel
that either (A) representation of such Indemnified Party and the Indemnifying
Party by the same counsel would be inappropriate under applicable standards of
professional conduct or (B) there may be one or more legal defenses available to
it which are different from or additional to those available to the Indemnifying
Party; provided, however, that the Indemnifying Party shall only have to pay the
fees and expenses of one firm of counsel for all Indemnified Parties in each
jurisdiction, except to the extent representation of all Indemnified Parties by
the same counsel is inappropriate under applicable standards of professional
conduct.  In either of such cases the Indemnifying Party shall not have the
right to assume the defense of such action on behalf of such Indemnified Party.
No Indemnifying Party shall be liable for any settlement entered into without
its written consent, which consent shall not be unreasonably withheld.  No
Indemnifying Party shall, without the written consent of the Indemnified Party,
effect the settlement or compromise of, or consent to the entry of any judgment
with respect to, any pending or threatened action or claim in respect of which
indemnification or contribution may

                                      -13-
<PAGE>
 
be sought hereunder (whether or not the Indemnified Party is an actual or
potential party to such action or claim) unless such settlement, compromise or
judgment (A) includes an unconditional release of the Indemnified Party from all
liability arising out of such action or claim and (B) does not include a
statement as to or an admission of fault, culpability or a failure to act, by or
on behalf of any Indemnified Party. The rights accorded to any Indemnified Party
hereunder shall be in addition to any rights that such Indemnified Party may
have at common law, by separate agreement or otherwise.

          (d) Contribution.  If the indemnification provided for in Section 8(a)
              ------------                                                      
from the Indemnifying Party is unavailable to an Indemnified Party in respect of
any losses, claims, damages, expenses or other liabilities referred to therein,
then the Indemnifying Party, in lieu of indemnifying such Indemnified Party,
shall contribute to the amount paid or payable by such Indemnified Party as a
result of such losses, claims, damages, expenses or other liabilities in such
proportion as is appropriate to reflect the relative fault of the Indemnifying
Party and Indemnified Party in connection with the actions which resulted in
such losses, claims, damages, expenses or other liabilities, as well as any
other relevant equitable considerations. The relative faults of such
Indemnifying Party and Indemnified Party shall be determined by reference to,
among other things, whether any action in question, including any untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact, was made by, or relates to information supplied by, such
Indemnifying Party or Indemnified Party, and the Indemnifying Party's and
Indemnified Party's relative intent, knowledge, access to information and
opportunity to correct or prevent such action.  The amount paid or payable by a
party as a result of the losses, claims, damages, expenses or other liabilities
referred to above shall be deemed to include, subject to the limitations set
forth in Section 8(a), 8(b) and 8(c), any legal or other fees, charges or
expenses reasonably incurred by such party in connection with any investigation
or proceeding.

          The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 8(d) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable con  siderations referred to in the immediately preceding
paragraph.  No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution pursuant to this
Section 8(d).

          9.   Rule 144; Other Exemptions.  The Company covenants that it shall
               --------------------------                                      
file any reports required to be filed by it under the Exchange Act and the rules
and regulations adopted by the SEC thereunder, and that it shall take such
further action as each Holder may reasonably request (including, but not limited
to, providing any information necessary to comply with Rules 144 and 144A under
the Act), all to the extent required from time to time to enable such Holder to
sell Registrable Securities without registration under the Act within the
limitation of the exemptions provided by (a) Rule 144 or Rule 144A under the
Act, as such rules may be amended from time to time, or (b) any other rules or
regulations now existing or hereafter adopted by the SEC.  The Company shall,
upon the request of any Holder, deliver to

                                      -14-
<PAGE>
 
such Holder a written statement as to whether the Company has complied with such
requirements.

          10.  Certain Limitations on Registration Rights.  In the case of a
               ------------------------------------------                   
registration under Section 4 if the Company has determined to enter into an
underwriting agreement in connection therewith, no person may participate in
such registration unless such person (a) agrees to sell such person's securities
on the basis provided therein and (b) completes and executes all questionnaires,
powers of attorney, indemnities, lock-up agreements, underwriting agreements and
other documents reasonably required under the terms of such underwriting
agreements.

          11.  Miscellaneous.
               ------------- 

               (a) Recapitalizations, Exchanges, etc.  The provisions of this
                   ---------------------------------                         
Agreement shall apply, to the full extent set forth herein with respect to the
Shares, to any and all shares of capital stock of the Company or any successor
or assign of the Company (whether by merger, consolidation, sale of assets or
otherwise) which may be issued in respect of, in exchange for or in substitution
of, the Shares and shall be appropriately adjusted for any stock dividends,
splits, reverse splits, combinations, recapitalizations and the like occurring
after the date hereof.

               (b) No Inconsistent Agreements; Other Registration Rights. The 
                   -----------------------------------------------------
Company shall not enter into any agreement with respect to its securities that
is inconsistent with or adversely affects the rights granted to the Holders in
this Agreement other than any lock-up agreement with the underwriters in
connection with an underwritten offering pursuant to which the Company agrees,
for a period not in excess of 90 days, not to register for sale, and not to sell
or otherwise dispose of, Common Stock or any securities convertible into or
exercisable or exchangeable for Common Stock. The Company shall not grant any
other Person registration rights without the written consent of the Designated
Holders holding at least a majority of the Registrable Securities held by all of
the Designated Holders. If the Company shall at any time hereafter provide to
any holder of any securities of the Company rights with respect to the
registration of such securities and such rights are provided on terms or
conditions more favorable to such holder than the terms and conditions
applicable to the Designated Holders herein, the Company shall provide (by way
of amendment to this Agreement or otherwise) such more favorable terms or
conditions to the Designated Holders under this Agreement.

               (c) Remedies.  The Holders, in addition to being entitled to 
                   --------    
exercise all rights granted by law, including recovery of damages, shall be
entitled to specific performance of their rights under this Agreement. The
Company agrees that monetary damages would not be adequate compensation for any
loss incurred by reason of a breach by it of the provisions of this Agreement
and hereby agrees to waive in any action for specific performance the defense
that a remedy at law would be adequate.

               (d) Amendments and Waivers.  Except as otherwise provided herein
                   ----------------------
the provisions of this Agreement may not be amended, modified or supplemented,

                                      -15-
<PAGE>
 
and waivers or consents to departures from the provisions of such section may
not be given unless the Company has obtained the prior written consent of (i)
the Designated Holders holding at least a majority of the Registrable Securities
held by all of the Designated Holders and (ii) the Holders holding at least a
majority of the Registrable Securities.

July 8, 1998

           NITINOL MEDICAL TECHNOLOGIES CLOSES ACQUISITION OF ELEKTA
           ---------------------------------------------------------
                   NEUROSURGICAL INSTRUMENTS FOR $33 MILLION
                   -----------------------------------------

BOSTON, MA, JULY 8, 1998 -- Nitinol Medical Technologies, Inc. (Nasdaq/NMS:NMTI)
today announced the closing of its acquisition of Elekta Neurosurgical
Instruments (ENI) from Elekta AB of Sweden for $33 million.

The acquisition will operate as a division of Nitinol Medical under the name NMT
Neurosciences and will be managed by David C. Chazanovitz, formerly President of
the Septal Repair Division of Nitinol Medical. Sales of the division are derived
from a broad range of specialty implants and instruments for neurosurgery,
including cerebral spinal fluid (CSF) shunts, the Selector(R) Ultrasonic
Aspirator, Ruggles/TM/ Surgical Instruments, the Spetzler/TM/ Titanium Aneurysm
Clip, and endoscopes and instrumentation for minimally invasive neurosurgery.
NMT Neurosciences has a leadership position in each of these product categories.
Sales of this division for the fiscal year ended April 30, 1998 were $38.0
million worldwide. NMT Neurosciences employs 267 people at locations primarily
in the United Kingdom, France, and Atlanta, Georgia. On a pro forma combined
basis for the calendar year 1997, including NMT Neurosciences, Nitinol Medical
would have had revenues of nearly $50 million.

Commenting on the acquisition, Thomas M. Tully, President and CEO of Nitinol
Medical Technologies, said, "NMT Neurosciences represents a profitable, growing,
fully integrated global business platform which we plan to further build through
additional acquisitions, licensing agreements and internal product developments.
With 38 sales and marketing employees around the world, and a high-quality
product line, we believe that we will have the most intensive focus on the
neurosurgeon of any company. Additionally, the important new technology
platforms and

manufacturing capabilities we are acquiring will significantly broaden our 
product development opportunities.

"This acquisition advances Nitinol Medical to the next level of medical device 
companies, and expands our offering of minimally invasive products.  With the 
significant increase in revenues and diversification of our product line 
accomplished by this acquisition, we believe we are better positioned for 
continued significant growth in revenue and profits."

The transaction was financed with $13 million of the Company's cash and $20 
million of subordinated debt from an affiliate of JH Whitney & Co., a 
significant stockholder of the Company.  The subordinated debt is due September 
30, 2003, with interest payable quarterly at 10.101% per annum.  A total of 
675,000 shares of common stock were issued to JH Whitney & Co. and its 
affiliates in connection with the transaction.

Nitinol Medical Technologies, Inc. designs, develops, and markets innovative 
medical devices that utilize advanced technologies and are delivered by 
minimally invasive procedures.  The Company's products are designed to offer 
alternative approaches to existing complex treatments, thereby reducing patient 
trauma, shortening procedure, hospitalization and recovery times, and lowering 
overall treatment costs.  The Company's patented medical devices include 
self-expanding stents, vena cava filters and septal repair devices.  Elekta AB 
is a leading international supplier of advanced medical technology for treatment
of neurological disorders and radiation of cancer.

This news release contains forward-looking statements within the meaning of the 
Private Securities Litigation Reform Act of 1995.  Such forward-looking 
statements involve risks and uncertainties that could cause actual results to 
differ from predicted results.  Achieving the anticipated benefits of the merger
will depend in part upon whether the integration of the two companies' 
businesses is accomplished in an efficient manner, and there can be no assurance
that this will occur.  The combination of the two companies will require, among 
other things, integration of the companies' respective product offerings, 
coordination of their sales and marketing organizations, and the research and 
development efforts.  There can be no assurance that integration will be 
accomplished smoothly or successfully.  The difficulties of such integration may
be increased by the necessity of coordinating geographically-separated 
organizations.  The integration of certain operations following the merger will 
require the dedication of management resources which may temporarily distract 
attention from the day-to-day business of the respective companies.  The 
inability of management to successfully integrate the operations of the two 
companies could have an adverse affect on the business and results of operations
of the combined companies.  In addition, there can be no assurance that present 
and potential customers of Elekta and Nitinol will continue their current buying
patterns and any significant delay or reduction in orders could have an adverse 
affect on the results of operations.  Further information on factors that could 
affect the combined company's results are included in "Management's Discussion 
and Analysis of Financial Condition and Results of Operations" in the Company's 
Annual Report on Form 10-K for the year ended December 31, 1997, and from time 
to time in Nitinol's other filings with the Securities and Exchange Commission.
