To the Holders of Common Stock of
Vivra Incorporated:
 
                                  INTRODUCTION
 
    Gambro Healthcare Acquisition Corp., a Delaware corporation ("Purchaser")
and an indirect wholly owned subsidiary of Incentive AB, a corporation organized
under the laws of Sweden ("Parent"), hereby offers to purchase all outstanding
shares of Common Stock, par value $.01 per share (the "Shares"), of Vivra
Incorporated, a Delaware corporation (the "Company"), at a price of $35.62 per
Share (such amount or any greater amount per Share paid pursuant to the Offer
(as defined below), being hereinafter referred to as the "Per Share Amount"),
net to the seller in cash, upon the terms and subject to the conditions set
forth in this Offer to Purchase and in the related Letter of Transmittal (which
together constitute the "Offer").
 
    Tendering stockholders will not be obligated to pay brokerage fees or
commissions or, except as otherwise provided in Instruction 6 of the Letter of
Transmittal, stock transfer taxes with respect to the purchase of Shares by
Purchaser pursuant to the Offer. Purchaser will pay all charges and expenses of
UBS Securities LLC ("UBS"), which is acting as Dealer Manager for the Offer (in
such capacity, the "Dealer Manager"), The Bank of New York (the "Depositary")
and Georgeson & Company Inc. (the "Information Agent") incurred in connection
with the Offer. See "Section 17. Fees and Expenses".
 
    THE BOARD OF DIRECTORS OF THE COMPANY (THE "BOARD") UNANIMOUSLY HAS
DETERMINED THAT EACH OF THE OFFER AND THE MERGER (AS DEFINED BELOW) IS FAIR TO,
AND IN THE BEST INTERESTS OF, THE STOCKHOLDERS OF THE COMPANY, AND RECOMMENDS
THAT STOCKHOLDERS ACCEPT AND TENDER THEIR SHARES PURSUANT TO THE OFFER.
 
    THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, (I) THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER AT LEAST A
MAJORITY OF THE SHARES OUTSTANDING ON A FULLY DILUTED BASIS, (II) THE EXPIRATION
OR TERMINATION OF ANY APPLICABLE WAITING PERIOD UNDER THE HART-SCOTT-RODINO
ANTITRUST IMPROVEMENTS ACT OF 1976, AND (III) THE CONSUMMATION OF THE SPECIALTY
MERGER TRANSACTION (AS DESCRIBED HEREIN) AND THE RECEIPT BY THE COMPANY OF CASH
PROCEEDS THEREFOR, AFTER PROVIDING FOR ALL APPLICABLE INCOME TAXES (USING AN
ASSUMED INCOME TAX RATE OF 41%), OF NOT LESS THAN $76,900,000. THE OFFER IS ALSO
SUBJECT TO OTHER TERMS AND CONDITIONS WHICH ARE CONTAINED IN THIS OFFER TO
PURCHASE. SEE "SECTION 15. CERTAIN CONDITIONS OF THE OFFER".
 
    The Offer is being made pursuant to an Agreement and Plan of Merger dated as
of May 5, 1997 (the "Merger Agreement") among Parent, Purchaser and the Company.
The Merger Agreement provides that, among other things, as soon as practicable
after the purchase of Shares pursuant to the Offer and the satisfaction of the
other conditions set forth in the Merger Agreement and in accordance with the
relevant provisions of the General Corporation Law of the State of Delaware
("Delaware Law"), Purchaser will be merged with and into the Company (the
"Merger"). Following consummation of the Merger, the Company will continue as
the surviving corporation (the "Surviving Corporation") and will become an
indirect wholly owned subsidiary of Parent. At the effective time of the Merger
(the "Effective Time"), each Share issued and outstanding immediately prior to
the Effective Time (other than Shares held in the treasury of the Company or
owned by Purchaser, Parent or any direct or indirect wholly owned subsidiary of
Parent or of the Company, and other than Shares held by stockholders who shall
have demanded and perfected appraisal rights, if any, under Delaware Law) will
be cancelled and converted automatically into the right to receive $35.62 in
cash, or any higher price that may be paid per Share in the Offer, without
interest (the "Merger Consideration"). The Merger Agreement is more fully
described in "Section 11. Background of the Offer; Contacts with the Company;
the Merger Agreement and the Specialty Merger Agreement".
 
    The Merger Agreement provides that, promptly upon the purchase by Purchaser
of Shares pursuant to the Offer and from time to time thereafter, Purchaser
shall be entitled to designate up to such number of directors, rounded up to the
next whole number, on the Board as will give Purchaser representation on the
Board equal to the product of the number of directors on the Board multiplied by
the percentage that the aggregate number of Shares then beneficially owned by
Purchaser and its affiliates following such
<PAGE>
purchase bears to the total number of Shares then outstanding. In the Merger
Agreement, the Company has agreed to take all actions necessary to cause
Purchaser's designees to be elected as directors of the Company, including
increasing the size of the Board or securing the resignations of incumbent
directors or both.
 
    The consummation of the Merger is subject to the satisfaction or waiver of
certain conditions, including the approval and adoption of the Merger Agreement
by the requisite vote of the stockholders of the Company. See "Section 12.
Purpose of the Offer; Plans for the Company After the Offer and the Merger".
Under the Company's Certificate of Incorporation and Delaware Law, the
affirmative vote of the holders of a majority of the outstanding Shares is
required to approve and adopt the Merger Agreement and the Merger. Consequently,
if Purchaser acquires (pursuant to the Offer or otherwise) at least a majority
of the outstanding Shares, Purchaser will have sufficient voting power to
approve and adopt the Merger Agreement and the Merger without the vote of any
other stockholder.
 
    Under Delaware Law, if Purchaser acquires, pursuant to the Offer or
otherwise, at least 90% of the then outstanding Shares, Purchaser will be able
to approve and adopt the Merger Agreement and the transactions contemplated
thereby, including the Merger, without a vote of the Company's stockholders. In
such event, Parent, Purchaser and the Company have agreed to take, at the
request of Purchaser, all necessary and appropriate action to cause the Merger
to become effective as soon as reasonably practicable after such acquisition,
without a meeting of the Company's stockholders. If, however, Purchaser does not
acquire at least 90% of the then outstanding Shares pursuant to the Offer or
otherwise and a vote of the Company's stockholders is required under Delaware
Law, a significantly longer period of time will be required to effect the
Merger. See "Section 12. Purpose of the Offer; Plans for the Company After the
Offer and the Merger".
 
    The Company has advised Purchaser that as of May 5, 1997, 41,991,547 Shares
were issued and outstanding, 2,711,133 Shares were reserved for issuance
pursuant to outstanding stock options granted by the Company to employees and
directors and 4,261,963 Shares were reserved for issuance upon conversion of the
Company's 5% Convertible Subordinated Notes Due 2001 (the "Convertible Notes").
As a result, as of such date, the Minimum Condition would be satisfied if
Purchaser acquired 24,482,322 Shares.
 
    Simultaneously with the execution of the Merger Agreement, the Company
entered into an Agreement and Plan of Reorganization (the "Specialty Merger
Agreement"), dated as of May 5, 1997, by and between VSP Holdings, Inc., a
Delaware corporation ("VSP Purchaser"), VSP Holdings II, Inc., a Delaware
corporation ("VSP Purchaser II"), VSP Acquisition, Inc., a Delaware corporation
and a wholly owned subsidiary of VSP Purchaser ("VSP Merger Sub" and, together
with VSP Purchaser and VSP Purchaser II, the "VSP Purchasers"), Vivra Specialty
Partners, Inc., a Nevada Corporation and a majority owned subsidiary of the
Company ("Specialty Partners"), and the Company. Pursuant to the Specialty
Merger Agreement, the Company will sell its interests in Specialty Partners and
in Vivra Heart Imaging, Inc., a Nevada corporation and a majority owned
subsidiary of the Company ("VHI") to the VSP Purchasers (the "Specialty Merger
Transaction").
 
    Of the Per Share Amount, $1.72 represents the expected net after-tax
proceeds per Share to the Company from the Specialty Merger Transaction. Under
the Specialty Merger Agreement, the gross consideration allocated between
Specialty Partners and VHI will be $84,312,500. Of this amount, the Company
expects to receive sale proceeds of approximately $79,400,000. Assuming both a
pre-tax gain to the Company of approximately $5,400,000 and an income tax rate
of 41%, the Company will incur a tax liability of approximately $2,200,000 in
connection with the Specialty Merger Transaction. The net after-tax proceeds of
approximately $77,200,000 represents approximately $1.72 per Share on a fully
diluted basis. The receipt by the Company of not less than $76,900,000 of such
net after-tax proceeds is a condition to the purchase of the Shares in the
Offer. See "Section 15. Conditions of the Offer."
 
                                       2
<PAGE>
    THE OFFER IS NOT BEING MADE FOR (NOR WILL TENDERS BE ACCEPTED OF) ANY OF THE
CONVERTIBLE NOTES. Holders of Convertible Notes who wish to participate in the
Offer must first convert their Convertible Notes into Shares in accordance with
the terms of the Indenture dated as of July 8, 1996 (the "Indenture") between
the Company and State Street Bank and Trust Company, as trustee (the "Trustee"),
and tender the Shares issued upon such conversion pursuant to the Offer. Under
the Indenture, any holder of Convertible Notes may, at his option, convert the
principal amount thereof into that number of Shares obtained by dividing the
principal amount thereof by the conversion price of $37.20 (26.88 shares per
$1,000 principal amount of Convertible Notes), subject to adjustment under
certain circumstances. Holders of Convertible Notes who convert such Convertible
Notes into Shares will have no right under the Indenture to revoke an effective
conversion. Accordingly, if the Offer terminates or expires without the purchase
of Shares or if Shares tendered after conversion by a holder of Convertible
Notes are not purchased for any reason, the converting holder will no longer
have any rights under the Indenture. According to the Indenture, after
consummation of the Merger, each holder of a Convertible Note then outstanding
would be entitled to receive, upon conversion, the consideration receivable upon
consummation of the Merger by the holder of the number of Shares that would have
been deliverable upon conversion of such Convertible Notes immediately prior to
the Merger; or $957.47 per $1,000 principal amount of Convertible Notes.
 
    Subject to the terms and conditions of the Indenture, upon the consummation
of the Offer, the holders of Convertible Notes, will have the right to require
the Company to repurchase their Convertible Notes at a purchase price equal to
the principal amount thereof plus accrued interest (up to and including the date
of repurchase). See "Section 9. Effect on Convertible Notes".
 
    THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION WHICH SHOULD BE READ BEFORE ANY DECISION IS MADE WITH
RESPECT TO THE OFFER.
 
    1. TERMS OF THE OFFER; EXPIRATION DATE. Upon the terms and subject to the
conditions of the Offer (including, if the Offer is extended or amended, the
terms and conditions of such extension or amendment), Purchaser will accept for
payment and pay for all Shares validly tendered prior to the Expiration Date (as
hereinafter defined) and not withdrawn as permitted by "Section 4. Withdrawal
Rights". The term "Expiration Date" means 12:00 midnight, New York City time, on
Friday, June 6, 1997, unless and until Purchaser, in its sole discretion (but
subject to the terms and conditions of the Merger Agreement), shall have
extended the period during which the Offer is open, in which event the term
"Expiration Date" shall mean the latest time and date at which the Offer, as so
extended by Purchaser, shall expire.
 
    Purchaser expressly reserves the right, in its sole discretion (but subject
to the terms and conditions of the Merger Agreement), at any time and from time
to time, to extend for any reason the period of time during which the Offer is
open, including the occurrence of any of the conditions specified in "Section
15. Certain Conditions of the Offer", by giving oral or written notice of such
extension to the Depositary. During any such extension, all Shares previously
tendered and not withdrawn will remain subject to the Offer, subject to the
rights of a tendering stockholder to withdraw such stockholder's shares. See
"Section 4. Withdrawal Rights".
 
    Subject to the applicable regulations of the Securities and Exchange
Commission (the "Commission"), Purchaser also expressly reserves the right, in
its sole discretion (but subject to the terms and conditions of the Merger
Agreement), at any time and from time to time, (i) to delay acceptance for
payment of, or, regardless of whether such Shares were theretofore accepted for
payment, payment for, any Shares pending receipt of any regulatory approval
specified in "Section 16. Certain Legal Matters and Regulatory Approvals", (ii)
to terminate the Offer and not accept for payment any Shares upon the occurrence
of any of the conditions specified in "Section 15. Certain Conditions of the
Offer" and (iii) to waive any condition or otherwise amend the Offer in any
respect, by giving oral or written notice of such delay, termination, waiver or
amendment to the Depositary and by making a public announcement thereof. The
Merger Agreement provides that, without the consent of the Company, Purchaser
will not
 
                                       3
<PAGE>
(i) decrease the price per Share payable pursuant to the Offer, (ii) reduce the
maximum number of Shares to be purchased in the Offer or (iii) impose conditions
to the Offer in addition to those set forth in "Section 15. Certain Conditions
of the Offer". Purchaser acknowledges that (i) Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), requires
Purchaser to pay the consideration offered or to return the Shares tendered
promptly after the termination or withdrawal of the Offer and (ii) Purchaser may
not delay acceptance for payment of, or payment for (except as provided in
clause (i) of the first sentence of this paragraph), any Shares upon the
occurrence of any of the conditions specified in "Section 15. Certain Conditions
of the Offer" without extending the period of time during which the Offer is
open.
 
    Any such extension, delay, termination, waiver or amendment will be followed
as promptly as practicable by public announcement thereof, such announcement in
the case of an extension to be made no later than 9:00 a.m., New York City time,
on the next business day after the previously scheduled Expiration Date. Subject
to applicable law (including Rules 14d-4(c) and 14d-6(d) under the Exchange Act,
which require that material changes be promptly disseminated to stockholders in
a manner reasonably designed to inform them of such changes) and without
limiting the manner in which Purchaser may choose to make any public
announcement, Purchaser shall have no obligation to publish, advertise or
otherwise communicate any such public announcement other than by issuing a press
release to the Dow Jones News Service.
 
    If Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer, or if it waives a material condition of the
Offer, Purchaser will extend the Offer to the extent required by Rules l4d-4(c)
and l4d-6(d) under the Exchange Act.
 
    Subject to the terms of the Merger Agreement, if, prior to the Expiration
Date, Purchaser should decide to decrease the number of Shares being sought or
to increase or decrease the consideration being offered in the Offer, such
decrease in the number of Shares being sought or such increase or decrease in
the consideration being offered will be applicable to all stockholders whose
Shares are accepted for payment pursuant to the Offer and, if at the time notice
of any such decrease in the number of Shares being sought or such increase or
decrease in the consideration being offered is first published, sent or given to
holders of such Shares, the Offer is scheduled to expire at any time earlier
than the period ending on the tenth business day from and including the date
that such notice is first so published, sent or given, the Offer will be
extended at least until the expiration of such ten business day period. For
purposes of the Offer, a "business day" means any day other than a Saturday,
Sunday or federal holiday and consists of the time period from 12:01 a.m.
through 12:00 midnight, New York City time.
 
    The Company has provided Purchaser with the Company's stockholder list and
security position listings for the purpose of disseminating the Offer to holders
of Shares. This Offer to Purchase and the related Letter of Transmittal will be
mailed to record holders of Shares whose names appear on the Company's
stockholder list and will be furnished, for subsequent transmittal to beneficial
owners of Shares, to brokers, dealers, commercial banks, trust companies and
similar persons whose names, or the names of whose nominees, appear on the
stockholder list or, if applicable, who are listed as participants in a clearing
agency's security position listing.
 
    2. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES. Upon the terms and subject
to the conditions of the Offer (including, if the Offer is extended or amended,
the terms and conditions of any such extension or amendment), Purchaser will
accept for payment, and will pay for, all Shares validly tendered prior to the
Expiration Date and not properly withdrawn promptly after the later to occur of
(i) the Expiration Date, (ii) the expiration or termination of any applicable
waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended (the "HSR Act"), and (iii) the satisfaction or waiver of the
conditions to the Offer set forth in "Section 15. Certain Conditions of the
Offer". Subject to applicable rules of the Commission, Purchaser expressly
reserves the right to delay acceptance for payment of, or payment for, Shares
pending receipt of any regulatory approvals specified in "Section 16.
 
                                       4
<PAGE>
Certain Legal Matters and Regulatory Approvals" or in order to comply, in whole
or in part, with any other applicable law.
 
    In all cases, payment for Shares tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of (i) the
certificates evidencing such Shares (the "Share Certificates") or timely
confirmation (a "Book-Entry Confirmation") of a book-entry transfer of such
Shares into the Depositary's account at The Depository Trust Company, the
Midwest Securities Trust Company or the Philadelphia Depository Trust Company
(each, a "Book-Entry Transfer Facility" and, collectively, the "Book-Entry
Transfer Facilities") pursuant to the procedures set forth in "Section 3.
Procedures for Accepting the Offer and Tendering Shares", (ii) the Letter of
Transmittal (or a facsimile thereof), properly completed and duly executed, with
any required signature guarantees and (iii) any other documents required under
the Letter of Transmittal.
 
    On May 9, 1997, Parent filed with the Federal Trade Commission (the "FTC")
and the Antitrust Division of the Department of Justice (the "Antitrust
Division") a Premerger Notification and Report Form under the HSR Act with
respect to the Offer. Accordingly, it is anticipated that the waiting period
under the HSR Act applicable to the Offer will expire at 11:59 p.m., New York
City time, on May 24, 1997. Prior to the expiration or termination of such
waiting period, the FTC or the Antitrust Division may extend such waiting period
by requesting additional information from Parent with respect to the Offer. If
such a request is made with respect to the purchase of Shares in the Offer, the
waiting period will expire at 11:59 p.m., New York City time, on the tenth
calendar day after substantial compliance by Parent with such a request.
Thereafter, the waiting period may only be extended by court order. The waiting
period under the HSR Act may be terminated prior to its expiration by the FTC
and the Antitrust Division. Parent has requested early termination of the
waiting period, although there can be no assurance that this request will be
granted. See "Section 16. Certain Legal Matters and Regulatory Approvals" for
additional information regarding the HSR Act.
 
    For purposes of the Offer, Purchaser will be deemed to have accepted for
payment (and thereby purchased) Shares validly tendered and not properly
withdrawn as, if and when Purchaser gives oral or written notice to the
Depositary of Purchaser's acceptance for payment of such Shares pursuant to the
Offer. Upon the terms and subject to the conditions of the Offer, payment for
Shares accepted for payment pursuant to the Offer will be made by deposit of the
purchase price therefor with the Depositary, which will act as agent for
tendering stockholders for the purpose of receiving payments from Purchaser and
transmitting such payments to tendering stockholders whose Shares have been
accepted for payment. Under no circumstances will interest on the purchase price
for Shares be paid, regardless of any delay in making such payment.
 
    If any tendered Shares are not accepted for payment for any reason pursuant
to the terms and conditions of the Offer, or if Share Certificates are submitted
evidencing more Shares than are tendered, Share Certificates evidencing
unpurchased Shares will be returned, without expense to the tendering
stockholder (or, in the case of Shares tendered by book-entry transfer into the
Depositary's account at a Book-Entry Transfer Facility pursuant to the procedure
set forth in "Section 3. Procedures for Accepting the Offer and Tendering
Shares", such Shares will be credited to an account maintained at such Book-
Entry Transfer Facility), as promptly as practicable following the expiration or
termination of the Offer.
 
    Purchaser reserves the right to transfer or assign, in whole or from time to
time in part, to one or more of its affiliates, the right to purchase all or any
portion of the Shares tendered pursuant to the Offer, but any such transfer or
assignment will not relieve Purchaser of its obligations under the Offer and
will in no way prejudice the rights of tendering stockholders to receive payment
for Shares validly tendered and accepted for payment pursuant to the Offer.
 
    3. PROCEDURES FOR ACCEPTING THE OFFER AND TENDERING SHARES. In order for a
holder of Shares validly to tender Shares pursuant to the Offer, the Letter of
Transmittal (or a facsimile thereof), properly completed and duly executed,
together with any required signature guarantees (or, in the case of a book-entry
 
                                       5
<PAGE>
transfer, an Agent's Message in lieu of the Letter of Transmittal) and any other
documents required by the Letter of Transmittal, must be received by the
Depositary at one of its addresses set forth on the back cover of this Offer to
Purchase and either (i) the Share Certificates evidencing tendered Shares must
be received by the Depositary at such address or such Shares must be tendered
pursuant to the procedure for book-entry transfer described below and a
Book-Entry Confirmation must be received by the Depositary (including an Agent's
Message if the tendering stockholder has not delivered a Letter of Transmittal),
in each case prior to the Expiration Date, or (ii) the tendering stockholder
must comply with the guaranteed delivery procedures described below. The term
"Agent's Message" means a message, transmitted by a Book-Entry Transfer Facility
to, and received by, the Depositary and forming a part of a Book-Entry
Confirmation, which states that such Book-Entry Transfer Facility has received
an express acknowledgement from the participant in such Book-Entry Transfer
Facility tendering the Shares which are the subject of such book-entry
confirmation, that such participant has received and agrees to be bound by the
terms of the Letter of Transmittal and that Purchaser may enforce such agreement
against such participant.
 
    THE METHOD OF DELIVERY OF SHARE CERTIFICATES AND ALL OTHER REQUIRED
DOCUMENTS, INCLUDING DELIVERY THROUGH ANY BOOK-ENTRY TRANSFER FACILITY, IS AT
THE OPTION AND RISK OF THE TENDERING STOCKHOLDER, AND THE DELIVERY WILL BE
DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF DELIVERY IS BY
MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY
DELIVERY.
 
    BOOK-ENTRY TRANSFER.  The Depositary will establish accounts with respect to
the Shares at the Book-Entry Transfer Facilities for purposes of the Offer
within two business days after the date of this Offer to Purchase. Any financial
institution that is a participant in the system of any Book-Entry Transfer
Facility may make a book-entry delivery of Shares by causing such Book-Entry
Transfer Facility to transfer such Shares into the Depositary's account at such
Book-Entry Transfer Facility in accordance with such Book-Entry Transfer
Facility's procedures for such transfer. However, although delivery of Shares
may be effected through book-entry transfer at a Book-Entry Transfer Facility,
the Letter of Transmittal (or a facsimile thereof), properly completed and duly
executed, together with any required signature guarantees, or an Agent's Message
in lieu of the Letter of Transmittal, and any other required documents, must, in
any case, be received by the Depositary at one of its addresses set forth on the
back cover of this Offer to Purchase prior to the Expiration Date, or the
tendering stockholder must comply with the guaranteed delivery procedure
described below. Delivery of documents to a Book-Entry Transfer Facility does
not constitute delivery to the Depositary.
 
    SIGNATURE GUARANTEES.  Signatures on all Letters of Transmittal must be
guaranteed by a firm which is a member of a registered national securities
exchange or of the National Association of Securities Dealers, Inc., or by a
commercial bank or trust company having an office or correspondent in the United
States (each of the foregoing being referred to as an "Eligible Institution"),
except in cases where Shares are tendered (i) by a registered holder of Shares
who has not completed either the box entitled "Special Payment Instructions" or
the box entitled "Special Delivery Instructions" on the Letter of Transmittal or
(ii) for the account of an Eligible Institution. If a Share Certificate is
registered in the name of a person other than the signer of the Letter of
Transmittal, or if payment is to be made, or a Share Certificate not accepted
for payment or not tendered is to be returned, to a person other than the
registered holder(s), then the Share Certificate must be endorsed or accompanied
by appropriate stock powers, in either case signed exactly as the name(s) of the
registered holder(s) appear on the Share Certificate, with the signature(s) on
such Share Certificate or stock powers guaranteed by an Eligible Institution.
See Instructions 1 and 5 of the Letter of Transmittal.
 
    GUARANTEED DELIVERY.  If a stockholder desires to tender Shares pursuant to
the Offer and such stockholder's Share Certificates evidencing such Shares are
not immediately available or such stockholder cannot deliver the Share
Certificates and all other required documents to the Depositary prior to
 
                                       6
<PAGE>
the Expiration Date, or such stockholder cannot complete the procedure for
delivery by book-entry transfer on a timely basis, such Shares may nevertheless
be tendered, provided that all the following conditions are satisfied:
 
    (i) such tender is made by or through an Eligible Institution;
 
    (ii) a properly completed and duly executed Notice of Guaranteed Delivery,
substantially in the form made available by Purchaser, is received prior to the
Expiration Date by the Depositary as provided below; and
 
    (iii) the Share Certificates (or a Book-Entry Confirmation) evidencing all
tendered Shares, in proper form for transfer, in each case together with the
Letter of Transmittal (or a facsimile thereof), properly completed and duly
executed, with any required signature guarantees, and any other documents
required by the Letter of Transmittal are received by the Depositary within
three New York Stock Exchange, Inc. ("NYSE") trading days after the date of
execution of such Notice of Guaranteed Delivery.
 
    The Notice of Guaranteed Delivery may be delivered by hand or mail or
transmitted by telegram, telex or facsimile transmission to the Depositary and
must include a guarantee by an Eligible Institution in the form set forth in the
form of Notice of Guaranteed Delivery made available by Purchaser.
 
    In all cases, payment for Shares tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of the
Share Certificates evidencing such Shares, or a Book-Entry Confirmation of the
delivery of such Shares, and the Letter of Transmittal (or a facsimile thereof),
properly completed and duly executed, with any required signature guarantees,
and any other documents required by the Letter of Transmittal.
 
    DETERMINATION OF VALIDITY.  All questions as to the validity, form,
eligibility (including time of receipt) and acceptance for payment of any tender
of Shares will be determined by Purchaser in its sole discretion, which
determination shall be final and binding on all parties. Purchaser reserves the
absolute right to reject any and all tenders determined by it not to be in
proper form or the acceptance for payment of which may, in the opinion of its
counsel, be unlawful. Purchaser also reserves the absolute right to waive any
condition of the Offer or any defect or irregularity, in the tender of any
Shares of any particular stockholder, whether or not similar defects or
irregularities are waived in the case of other stockholders. No tender of Shares
will be deemed to have been validly made until all defects and irregularities
have been cured or waived. None of Purchaser, Parent, the Dealer Manager, the
Depositary, the Information Agent or any other person will be under any duty to
give notification of any defects or irregularities in tenders or incur any
liability for failure to give any such notification. Purchaser's interpretation
of the terms and conditions of the Offer (including the Letter of Transmittal
and the instructions thereto) will be final and binding.
 
    OTHER REQUIREMENTS.  By executing the Letter of Transmittal as set forth
above, a tendering stockholder irrevocably appoints designees of Purchaser as
such stockholder's proxies, each with full power of substitution, in the manner
set forth in the Letter of Transmittal, to the full extent of such stockholder's
rights with respect to the Shares tendered by such stockholder and accepted for
payment by Purchaser (and with respect to any and all other Shares or other
securities issued or issuable in respect of such Shares on or after May 5,
1997). All such proxies shall be considered coupled with an interest in the
tendered Shares. Such appointment will be effective when, and only to the extent
that, Purchaser accepts such Shares for payment. Upon such acceptance for
payment, all prior proxies given by such stockholder with respect to such Shares
(and such other Shares and securities) will be revoked without further action,
and no subsequent proxies may be given nor any subsequent written consent
executed by such stockholder (and, if given or executed, will not be deemed to
be effective) with respect thereto. The designees of Purchaser will, with
respect to the Shares for which the appointment is effective, be empowered to
exercise all voting and other rights of such stockholder as they in their sole
discretion may deem proper at any annual or special meeting of the Company's
stockholders or any adjournment or postponement
 
                                       7
<PAGE>
thereof, by written consent in lieu of any such meeting or otherwise. Purchaser
reserves the right to require that, in order for Shares to be deemed validly
tendered, immediately upon Purchaser's payment for such Shares, Purchaser must
be able to exercise full voting rights with respect to such Shares.
 
    The acceptance for payment by Purchaser of Shares pursuant to any of the
procedures described above will constitute a binding agreement between the
tendering stockholder and Purchaser upon the terms and subject to the conditions
of the Offer.
 
    TO PREVENT BACKUP FEDERAL INCOME TAX WITHHOLDING WITH RESPECT TO PAYMENT TO
CERTAIN STOCKHOLDERS OF THE PURCHASE PRICE OF SHARES PURCHASED PURSUANT TO THE
OFFER, EACH SUCH STOCKHOLDER MUST PROVIDE THE DEPOSITARY WITH SUCH STOCKHOLDER'S
CORRECT TAXPAYER IDENTIFICATION NUMBER AND CERTIFY THAT SUCH STOCKHOLDER IS NOT
SUBJECT TO BACKUP FEDERAL INCOME TAX WITHHOLDING BY COMPLETING THE SUBSTITUTE
FORM W-9 IN THE LETTER OF TRANSMITTAL. SEE INSTRUCTION 10 OF THE LETTER OF
TRANSMITTAL.
 
    4. WITHDRAWAL RIGHTS. Tenders of Shares made pursuant to the Offer are
irrevocable except that such Shares may be withdrawn at any time prior to the
Expiration Date and, unless theretofore accepted for payment by Purchaser
pursuant to the Offer, may also be withdrawn at any time after July 7, 1997. If
Purchaser extends the Offer, is delayed in its acceptance for payment of Shares
or is unable to accept Shares for payment pursuant to the Offer for any reason,
then, without prejudice to Purchaser's rights under the Offer, the Depositary
may, nevertheless, on behalf of Purchaser, retain tendered Shares, and such
Shares may not be withdrawn except to the extent that tendering stockholders are
entitled to withdrawal rights as described in this "Section 4. Withdrawal
Rights". Any such delay will be by an extension of the Offer to the extent
required by law.
 
    For a withdrawal to be effective, a written, telegraphic, telex or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover page of this Offer to Purchase.
Any such notice of withdrawal must specify the name of the person who tendered
the Shares to be withdrawn, the number of Shares to be withdrawn and the name of
the registered holder of such Shares, if different from that of the person who
tendered such Shares. If Share Certificates evidencing Shares to be withdrawn
have been delivered or otherwise identified to the Depositary, then, prior to
the physical release of such Share Certificates, the serial numbers shown on
such Share Certificates must be submitted to the Depositary and the signature(s)
on the notice of withdrawal must be guaranteed by an Eligible Institution,
unless such Shares have been tendered for the account of an Eligible
Institution. If Shares have been tendered pursuant to the procedure for
book-entry transfer as set forth in "Section 3. Procedures for Accepting the
Offer and Tendering Shares", any notice of withdrawal must specify the name and
number of the account at the Book-Entry Transfer Facility to be credited with
the withdrawn Shares.
 
    All questions as to the form and validity (including time of receipt) of any
notice of withdrawal will be determined by Purchaser, in its sole discretion,
whose determination will be final and binding. None of Purchaser, Parent, the
Dealer Manager, the Depositary, the Information Agent or any other person will
be under any duty to give notification of any defects or irregularities in any
notice of withdrawal or incur any liability for failure to give any such
notification.
 
    Any Shares properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the Offer. However, withdrawn Shares may be
re-tendered at any time prior to the Expiration Date by following one of the
procedures described in "Section 3. Procedures for Accepting the Offer and
Tendering Shares".
 
    5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES. The receipt of cash for Shares
pursuant to the Offer or in the Merger will be a taxable transaction for U.S.
federal income tax purposes under the Internal Revenue Code of 1986, as amended,
and may also be a taxable transaction under applicable state, local or foreign
tax laws. In general, a stockholder will recognize gain or loss for U.S. federal
income tax purposes
 
                                       8
<PAGE>
equal to the difference between the amount of cash received in exchange for the
Shares sold and such stockholder's adjusted tax basis in such Shares. Assuming
the Shares constitute capital assets in the hands of the stockholder, such gain
or loss will be capital gain or loss and will be long term capital gain or loss
if the stockholder's holding period exceeds one year.
 
    Legislative proposals have been under consideration that would reduce the
rate of federal income taxation of certain capital gains. Such legislation, if
enacted, might apply only to gain realized on sales occurring after a date
specified in the legislation. It cannot be predicted whether any such
legislation ultimately will be enacted and, if enacted, what its effective date
will be.
 
    THE FOREGOING DISCUSSION MAY NOT BE APPLICABLE TO CERTAIN TYPES OF
STOCKHOLDERS, INCLUDING STOCKHOLDERS WHO ACQUIRED SHARES PURSUANT TO THE
EXERCISE OF EMPLOYEE STOCK OPTIONS OR OTHERWISE AS COMPENSATION, INDIVIDUALS WHO
ARE NOT CITIZENS OR RESIDENTS OF THE UNITED STATES AND FOREIGN CORPORATIONS.
 
    THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION ONLY AND IS BASED UPON PRESENT LAW. STOCKHOLDERS ARE URGED TO
CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE SPECIFIC TAX CONSEQUENCES OF THE
OFFER AND THE MERGER TO THEM, INCLUDING THE APPLICATION AND EFFECT OF THE
ALTERNATIVE MINIMUM TAX, AND STATE, LOCAL AND FOREIGN TAX LAWS.
 
    6. PRICE RANGE OF SHARES; DIVIDENDS. The Shares are listed and traded

    Although there is no legal or contractual restriction on the payment of
dividends by the Company, historically the Company has never declared or paid
dividends and has stated that it has no future plans to do so. The Company has
advised Purchaser that if the Offer and the Merger were not to be consummated,
it would expect to continue to retain any future earnings for the development of
its business.
 
    On May 2, 1997, the last full trading day prior to the announcement of the
execution of the Merger Agreement and of Purchaser's intention to commence the
Offer, the closing price per Share as reported on the NYSE was $28 1/4. On May
8, 1997, the last full trading day prior to the commencement of the Offer, the
closing price per Share as reported on the NYSE was $34 3/4.
 
    STOCKHOLDERS ARE URGED TO OBTAIN A CURRENT MARKET QUOTATION FOR THE SHARES.

    In connection with Parent's review of the Company and in the course of the
negotiations between the Company and Parent described in "Section 11. Background
of the Offer; Contacts with the Company; the Merger Agreement and the Specialty
Merger Agreement", the Company provided Parent with certain business and
financial information which Parent and Purchaser believe is not publicly
available, including, among other things, certain financial forecasts for VRC
prepared by the Company for the Company's 1997 and 1998 fiscal years (the "VRC
Forecasts"). The VRC Forecasts indicate that operating revenues are forecasted
to be $559.8 million in 1997 and $788.5 million in 1998, which reflects an
assumed annual revenue growth rate of 36.1% and 40.9% in 1997 and 1998,
respectively, primarily due to assumed additions of new patients at existing
dialysis centers and assumed acquisitions of new dialysis centers and physician
practice groups. Also, the VRC Forecasts indicate that earnings from continuing
operations before interest and taxes ("EBIT") are forecasted to be $109.2
million in 1997 and $140.0 million in 1998, which reflects an assumed EBIT
margin of 19.5% and 17.8% in 1997 and 1998, respectively. The decrease in such
margin is due primarily to an increase in the number of global capitated
agreements as a percentage of VRC's revenues and additional amortization

    8. CERTAIN INFORMATION CONCERNING PURCHASER AND PARENT. Purchaser, formerly
HH Acquisition Corp., is a newly incorporated Delaware corporation organized in
connection with the Offer and the Merger and has not carried on any activities
other than in connection with the Offer and the Merger. The principal offices of
Purchaser are located at 1185 Oak Street, Lakewood, Colorado 80215. Purchaser is
an indirect wholly owned subsidiary of Parent.
 
    Until immediately prior to the time that Purchaser will purchase Shares
pursuant to the Offer, it is not anticipated that Purchaser will have any
significant assets or liabilities or engage in activities other than those
incident to its formation and capitalization and the transactions contemplated
by the Offer and the Merger. Because Purchaser is newly formed and has minimal
assets and capitalization, no meaningful financial information regarding
Purchaser is available.
 
    Parent, Incentive AB (publ), is a corporation organized under the laws of
Sweden. Its principal offices are located at Hamngatan 2, Box 7373, S-10391,
Stockholm, Sweden. Parent is an international industrial group. Operations are
principally conducted in the medical technology, environment, materials handling
and development business areas. In addition, Parent has a substantial equity
interest in (i) ABB AB, which jointly with ABB AG, owns equal shares of ABB ASEA
Brown Boveri Ltd, a leading electrotechnical company with operations in a number
of business areas related to the production, distribution and utilization of
electrical power in electrical power generation, transmission and distribution,
industrial and building systems and rail transportation, and (ii) AB Electrolux,
one of the world's leading manufacturers of household appliances.
 
    The name, citizenship, business address, principal occupation or employment,
and five-year employment history for each of the directors and executive
officers of Purchaser and Parent and certain other information are set forth in
Schedule I hereto.
 
                                       12
<PAGE>
    Parent is not subject to the information reporting requirements of the
Exchange Act, and, accordingly, does not file reports or other information with
the Commission relating to its business, financial condition and other matters.
 
    Set forth below are certain selected consolidated financial information
relating to Parent and its subsidiaries for Parent's last three fiscal years.
The selected consolidated financial information has been prepared in Swedish
kronor in accordance with generally accepted accounting principles in Sweden
("Swedish GAAP"). Swedish GAAP differs in certain significant respects from
generally accepted accounting principles in the United States ("US GAAP"). A
summary of the significant differences between US GAAP and Swedish GAAP is set
forth below. Parent, however, believes that the differences are not material to
a decision by a holder of Shares whether to sell, tender or hold any Shares
because any such differences would not affect the ability of Parent to obtain
sufficient funds to pay for Shares to be acquired pursuant to the Offer and to
repay any funds which have been borrowed for such purpose. The amounts in the
table set forth below are in Swedish kronor unless otherwise indicated. The US
dollar amounts in the table set forth below for the year ended December 31, 1996
and the three months ended March 31, 1997 were determined by translating the
corresponding Swedish kronor amounts into US dollars using the noon buying rate
in New York City for cable transfers in Swedish kronor as certified for customs
purposes by the Federal Reserve Bank of New York on May 7, 1997 (the "Noon
Buying Rate"), which was SEK 7.7505 = $1.00. No representation is made that
Swedish kronor have been, could have been or could be, converted into US dollars
at that or any other rate.

    SUMMARY OF SIGNIFICANT DIFFERENCES BETWEEN US GAAP AND SWEDISH GAAP.  The
following is a summary of certain significant differences in generally accepted
accounting practices in Sweden and the United States with respect to
consolidated financial statements. The summary is not to be regarded as a
complete list of all of the differences between Swedish GAAP and US GAAP and
does not include disclosure differences between Swedish GAAP and US GAAP.
 
    ACCOUNTING FOR PENSIONS. According to Swedish GAAP, pension expenses are, in
general, recognized on the basis of funding requirements. In the United States,
FAS 87 (Employers' Accounting for Pensions) states that future salary increases,
inflation and other factors must be taken into account for computation of the
projected benefit obligation.
 
    DEFERRED TAXES. Under Swedish GAAP, deferred taxes are calculated on untaxed
reserves using the liability method. Certain temporary differences and deferred
tax assets are not recorded. Under US GAAP, a reserve for deferred taxes under
the liability method is required for all temporary differences. Deferred tax
assets may be reported only if it is probable that the tax benefit will be
utilized.
 
    CHANGES IN ACCOUNTING PRINCIPLES. According to Swedish GAAP, the accumulated
effect of changes in accounting principles is reported directly against equity.
According to US GAAP, the accumulated effect of changes in accounting principles
is reported in the income statement.
 
    FOREIGN CURRENCY TRANSLATION. FINANCIAL STATEMENTS OF FOREIGN
SUBSIDIARIES. Swedish GAAP requires that all components of equity to be
classified either as restricted equity (share capital and restricted reserves)
or unrestricted equity. Cumulative currency translation adjustments are included
in restricted reserves or as retained earnings. Under US GAAP, cumulative
currency translation adjustments are required to be stated as a separate item
under stockholders' equity. In addition, assets and liabilities in foreign
currencies which are not designated as and effective as hedges are required to
be translated using the exchange rate at the balance sheet date and the
resulting gains or losses recognized in income.
 
    RECEIVABLES AND PAYABLES IN FOREIGN CURRENCIES.  With respect to the
valuation of outstanding forward exchanges contracts covering future flows of
foreign currencies, Swedish GAAP normally requires that provisions for
unrealized losses are made to the extent that such losses exceed unrealized
gains. Unrealized gains in excess of unrealized losses are not credited to
income. Under US GAAP, forward exchange contracts are valued at market price and
gains and losses arising therefrom are included in income.
 
    LEASING. According to Swedish GAAP almost all leases are treated as
operating leases. According to US GAAP leases are treated as either operating or
financial leases.
 
    CONSOLIDATED ACCOUNTS. The consolidated accounts are prepared in accordance
with the purchase method. For Gambro's acquisition of the Hospa Group, however,
the pooling method was used. US GAAP would require purchase accounting for this
acquisition.
 
    GOODWILL. Acquired goodwill is amortized over ten years, or, in the event of
long-term strategic acquisitions, over a maximum of twenty years according to
Swedish GAAP. Under US GAAP, acquired goodwill is amortized over a maximum of
forty years.
 
    Except as described in this Offer to Purchase, (i) none of Purchaser, Parent
nor, to the knowledge of Purchaser and Parent, any of the persons listed in
Schedule I to this Offer to Purchase or any associate or majority-owned
subsidiary of Purchaser, Parent or any of the persons so listed beneficially
owns or has any right to acquire, directly or indirectly, any Shares and (ii)
none of Purchaser, Parent nor, to the knowledge of Purchaser and Parent, any of
the persons or entities referred to above nor any director, executive officer or
subsidiary of any of the foregoing has effected any transaction in the Shares
during the past 60 days.
 
    Except as provided in the Merger Agreement and as otherwise described in
this Offer to Purchase, none of Purchaser, Parent nor, to the knowledge of
Purchaser and Parent, any of the persons listed in Schedule I to this Offer to
Purchase, has any contract, arrangement, understanding or relationship with
 
                                       14
<PAGE>
any other person with respect to any securities of the Company, including, but
not limited to, any contract, arrangement, understanding or relationship
concerning the transfer or voting of such securities, joint ventures, loan or
option arrangements, puts or calls, guaranties of loans, guaranties against loss
or the giving or withholding of proxies. Except as set forth in this Offer to
Purchase, since December 1, 1993, neither Purchaser nor Parent nor, to the best
knowledge of Purchaser and Parent, any of the persons listed on Schedule I
hereto, has had any business relationship or transaction with the Company or any
of its executive officers, directors or affiliates that is required to be
reported under the rules and regulations of the Commission applicable to the
Offer. Except as set forth in this Offer to Purchase, since December 1, 1993,
there have been no contacts, negotiations or transactions between any of
Purchaser, Parent, or any of their respective subsidiaries or, to the best
knowledge of Purchaser and Parent, any of the persons listed in Schedule I to
this Offer to Purchase, on the one hand, and the Company or its affiliates, on
the other hand, concerning a merger, consolidation or acquisition, tender offer
or other acquisition of securities, an election of directors or a sale or other
transfer of a material amount of assets.
 
    9. EFFECT ON CONVERTIBLE NOTES. The Indenture provides that upon a "Change
of Control" of the Company the holders of the Convertible Notes have the right
to require the Company to purchase their Convertible Notes for 100% of the
principal amount thereof, plus accrued and unpaid interest (up to and including
the date of repurchase). The consummation of the Offer on the terms described
herein will constitute a Change of Control under the Indenture. However, the
consummation of the Offer shall not be deemed to be a Change of Control for
purposes of the Indenture if (i) immediately following the date upon which the
Offer is consummated, the aggregate market value of the Shares, excluding the
Shares beneficially owned by Parent and Purchaser is equal to or greater than
$700,000,000 or (ii) the closing price per share of the Shares for any five
trading days within the period of 10 consecutive trading days ending immediately
after the later of the consummation of the Offer or the public announcement
thereof shall equal or exceed 105% of the conversion price of the Convertible
Notes (currently 105% of $37.20 or $39.06) in effect on each such trading day.
 
    According to the Indenture, within 30 days after the occurrence of such a
Change of Control, the Company will mail a written notice (the "Company Notice")
to the Trustee and to each holder of Convertible Notes and will cause a copy of
such notice to be published in a daily newspaper of national circulation. Such
notice will describe the Change of Control, the repurchase date, repurchase
price and the procedure for the holders to exercise their rights to require the
Company to repurchase their Convertible Notes. The date of repurchase of the
Convertible Notes will be designated by the Company so long as such date is not
less than 45 days nor more than 60 days after the date of the Company Notice.
 
    According to the Form 10-K, at November 30, 1996, $158,545,000 aggregate
principal amount of the Convertible Notes was outstanding. The Offer is not
being made for (nor will tenders be accepted of) any of the Convertible Notes.
Holders of Convertible Notes who wish to participate in the Offer must first
convert their Convertible Notes into Shares in accordance with the terms of the
Indenture, and then tender the Shares issued upon such conversion pursuant to
the Offer. Under the Indenture, any holder of Convertible Notes may, at his
option, convert the principal amount thereof into that number of Shares obtained
by dividing the principal amount thereof by the conversion price of $37.20
(currently 26.88 shares per $1,000 principal amount of Notes), subject to
adjustment under certain circumstances. Holders of Convertible Notes who convert
such Convertible Notes into Shares will have no right under the Indenture to
revoke an effective conversion. Accordingly, if the Offer terminates or expires
without the purchase of any Shares or if any Shares tendered after conversion by
any holder of Convertible Notes are not purchased for any reason, the converting
holders will no longer have any rights under the Indenture.
 
    Under the Indenture, after consummation of a merger, each holder of a
Convertible Note then outstanding would be entitled to receive, upon conversion,
the amount of shares of stock and other securities and property (including cash)
receivable upon such merger by the holder of the number of Shares which would
have been deliverable upon conversion of such Convertible Note immediately prior
 
                                       15
<PAGE>
to such merger. Accordingly, assuming a conversion price of $37.20 for the
Convertible Notes, each $1,000 principal amount of Convertible Notes would be
convertible into $957.47 upon consummation of the Merger.
 
    The Indenture requires that the Company, or the successor corporation,
execute and deliver to the Trustee, as a condition precedent to any such merger,
a supplemental indenture stating that holders of Convertible Notes shall have
the right to convert such Convertible Notes into the kind and amount of
consideration receivable if they had converted their Convertible Notes
immediately prior to the merger. In addition, the Indenture provides that the
Company may not consolidate with or merge into any corporation unless, among
other things, the acquiror is a US corporation and it expressly assumes (by a
supplemental indenture) the payment of principal and interest on the Convertible
Notes, as well as the Company's covenants under the Indenture.
 
    10. FINANCING OF THE OFFER AND THE MERGER.  The total amount of funds
required by Purchaser to consummate the Offer and the Merger, to repurchase the
Convertible Notes and to pay related fees and expenses is estimated to be
approximately $1.8 billion. Purchaser will obtain all of such funds from Parent
and its affiliates, including Gambro AB, a wholly owned subsidiary of Parent
("Gambro"). Gambro will provide to Purchaser to finance the Offer and the Merger
approximately $155 million from the Revolving Credit Facility, dated December
15, 1995 (the "Gambro Credit Facility"), between Gambro, BNP Capital Markets
Limited (as Arranger), certain banks named therein and Banque Nationale de Paris
(as Agent). Parent and Incentive Treasury AB, a subsidiary of Parent, will
provide to Purchaser to finance the Offer and the Merger (i) approximately $129
million from the Multicurrency Revolving Credit Facility, dated as of May 7,
1997 (the "1997 Credit Facility"), between Incentive Treasury AB (as Borrower),
Parent (as Guarantor) and Skandinaviska Enskilda Banken AB; (ii) approximately
$820 million from the Multicurrency Revolving Credit Facility, dated as of March
4, 1996 (the "1996 Credit Facility"), between Incentive Treasury AB (as
Borrower), Parent (as Guarantor), Deutsche Bank Luxembourg S.A. and Enskilda,
Skandinaviska Enskilda Banken (as Arrangers), Enskilda, Skandinaviska Enskilda
Banken (as Agent) and certain banks named therein; (iii) approximately $473
million from the Multicurrency Revolving Credit Facility, dated as of May 24,
1995, and amended March 4, 1996 (the "1995 Credit Facility"), between Incentive
Treasury AB (as Borrower), Parent (as Guarantor), Deutsche Bank Luxembourg S.A.
and Enskilda, Skandinaviska Enskilda Banken AB (as Arrangers) and Deutsche Bank
Luxembourg S.A. (as Agent) and certain banks named therein; (iv) approximately
$116 million from the Revolving Credit Facility, dated as of September 1, 1994,
and amended December 2, 1994, April 24, 1995, October 26, 1995 and November 5,
1996 (the "1994 Credit Facility"), between Parent (as First Borrower and
Guarantor), Incentive Treasury AB (as Second Borrower), Deutsche Bank Luxembourg
S.A. (as Lender); and (v) approximately $121 million from the Multicurrency
Credit Facility, dated as of March 6, 1996 (the "Nordbanken Credit Facility"),
between Nordbanken AB (as Lender), Incentive Treasury AB (as Borrower) and
Parent (as Guarantor).
 
    Purchaser, Gambro and Parent anticipate that any indebtedness incurred
through borrowings under the foregoing credit facilities will be repaid from a
variety of sources, which may include, but may not be limited to, funds
generated internally by Gambro, Parent and their affiliates (including,
following the Merger, funds generated by the Surviving Corporation), bank
refinancing, and the public or private sale of debt or equity securities. No
decision has been made concerning the method Gambro and Parent will employ to
repay such indebtedness. Such decision will be made based on a review from time
to time of the advisability of particular actions, as well as on prevailing
interest rates and financial and other economic conditions and such factors as
Gambro and Parent may deem appropriate.
 
    THE GAMBRO CREDIT FACILITY.  Under the Gambro Credit Facility, Gambro and
its designated subsidiaries may borrow up to a total of $300 million from the
banks that are signatories thereto. All loans under this facility must be repaid
in full by December 15, 2002, but may also be voluntarily prepaid. The annual
rate of interest on loans made under this facility is the aggregate of the
following: (i) 0.20% per annum from December 15, 1995 until December 15, 2000,
and 0.225% per annum thereafter, (ii) LIBOR (as

EIBOR (as defined in this facility) in the case of loans denominated in
sterling, and (iii) MLA Costs (as defined in this facility) when applicable to
such loan. Loan obligations under this facility rank at least PARI PASSU with

Subject to certain exceptions, an obligor under this facility may not create or
permit to subsist any security interest on any of its assets.
 
    THE 1997 CREDIT FACILITY.  Under the 1997 Credit Facility, Incentive
Treasury AB may borrow up to a total of 1 billion Swedish kronor from
Skandinaviska Enskilda Banken AB. Parent has guaranteed the obligations of
Incentive Treasury AB under this facility. Advances under this facility must be
repaid by May 5, 1998, and may be voluntarily prepaid only with the consent of
Skandinaviska Enskilda Banken AB. The annual rate of interest on loans made
under this facility is the aggregate of the following: (i) 0.10% per annum above
STIBOR (as defined in this facility) for loans in Swedish kronor and (ii) 0.10%

March 4, 2001. The annual rate of interest on loans made under this facility is
0.175% per annum over LIBOR (as defined in this facility). Loan obligations
under this facility rank at least PARI PASSU with the claims of obligor's other
unsecured creditors, except those whose claims are preferred by any bankruptcy,
insolvency, liquidation or other similar laws of general application. Subject to
certain exceptions, obligor may not create or permit to subsist any encumbrance
on any of its assets.
 
    THE 1995 CREDIT FACILITY.  Under the 1995 Credit Facility, Incentive
Treasury AB may borrow up to a total of $500 million from the banks that are
signatories thereto. Parent has guaranteed the obligations of Incentive Treasury
AB under the facility. All loans under this facility must be repaid in full by
May 24, 2002. The annual rate of interest on loans made under this facility is
the aggregate of the following: (i) 0.20% per annum from May 24, 1995 to May 24,
1999 and 0.25% per annum thereafter, (ii) the Associated Costs Rate (as defined
in this facility) in the case of loans denominated in sterling, and (iii) LIBOR
(as defined in this facility). Loan obligations under this facility rank at
least PARI PASSU with the claims of obligor's other unsecured creditors, except
those whose claims are preferred by any bankruptcy, insolvency, liquidation or
other similar laws of general application. Subject to certain exceptions,
obligor may not create or permit to subsist any encumbrance on any of its
assets.

    11. BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY; THE MERGER AGREEMENT
AND THE SPECIALTY MERGER AGREEMENT.
 
BACKGROUND OF THE OFFER, CONTACTS WITH THE COMPANY
 
    In late August and early September 1996, Mr. Thiry and Mr. Mats Wahlstrom,
President and Chief Executive Officer of Gambro Healthcare, Inc. ("Gambro
Healthcare"), a wholly owned subsidiary of Parent and Gambro, had discussions
concerning a possible strategic transaction between Parent and the Company.
Before and during September 1996, members of the Company's senior management,
including Mr. Thiry, Ms. Zumwalt and Stephen G. Pagliuca, a director of the
Company, interviewed various investment banking firms with respect to an
engagement to provide financial advice to the Company concerning its long-term
strategic direction and to potentially assist the Company in identifying an
acquiror for all or a portion of the Company's business. In September 1996, the
Company engaged Goldman Sachs to assist the Company in determining the proper
structure by which to achieve its objectives.
 
    In September 1996, Goldman, Sachs & Co., financial advisor to the Company
("Goldman Sachs"), on behalf of the Company, contacted several companies
regarding a potential strategic relationship with the Company, including Parent
and Purchaser. On September 19, 1996, UBS Securities LLC ("UBS"), financial
advisor to Gambro, forwarded to the Company certain materials concerning a
possible transaction structure. On September 25, 1996, Mr. Thiry met with
representatives of Parent and Gambro, including Berthold Lindqvist, President
and Chief Executive Officer of Gambro, Mikael Lilius, President and Chief
Executive Officer of Parent and Mr. Wahlstrom to discuss a potential acquisition
of the Company by Parents.
 
    On October 6, 1996, several representatives of Goldman Sachs met with
members of senior management of the Company to discuss potential transactions
and acquirors. On October 16, 1996, Mr. Thiry sent a letter to Parent and
Purchaser regarding certain structural issues involved in a potential
acquisition of the Company by Parent.
 
    On November 1, 1996, Mr. Thiry met with representatives of Parent and Gambro
to discuss outstanding structural issues and the feasibility of combining the
Company and Gambro Healthcare.  During November 1996, Mr. Thiry had discussions
with another company regarding a potential strategic relationship with the
Company. Also during November 1996, Goldman Sachs, on behalf of the Company, had
discussions with another company regarding a potential strategic relationship
with the Company.
 
    On November 18, 1996, the Company formally engaged Goldman Sachs to serve as
its financial advisor in connection with a potential acquisition of the Company
by a third party.
 
    On November 21, 1996, Mr. Wahlstrom, Herbert S. Lawson, Chief Financial
Officer of Gambro Healthcare, Mr. David Barry, President of the Company's Renal
division, and Ms. Zumwalt met in Colorado, together with representatives of
Goldman Sachs and UBS, to discuss certain financial data concerning Gambro and
the Company, including the operating synergies that might be expected from a
transaction.
 
    On November 25, 1996, representatives of UBS and Morgan Stanley & Co.
Limited ("Morgan Stanley"), financial advisor to Parent, met with
representatives of Goldman Sachs and presented an initial proposal for the
acquisition of the Company. The Company responded that the proposed terms were
below the Company's expectations. Mr. Thiry confirmed that response during a
subsequent telephone conversation. During December, the Company advised Gambro
that the Company would shift its focus to considering a transaction involving
the sale of all or part of VSP (the "VSP Sale").
 
    During December 1996, the Company had discussions with one company regarding
a potential strategic relationship with the Company. Also during December 1996,
Ms. Zumwalt met with representatives of a potential acquiror in connection with
the VSP Sale.
 
    During February 1997, the Company had discussions with two companies
regarding a potential strategic relationship with the Company. On February 5,
1997, Mr. Lindqvist sent a letter to the Company
 
                                       18
<PAGE>
indicating that Gambro would be prepared to make an offer to acquire all the
Shares for cash, or alternatively to acquire the Company's dialysis services and
renal care business. Mr. Lilius sent a letter contemporaneously to the Company
expressing Parent's support for Gambro's proposal.
 
    On February 7, 1997, the Company's Board of Directors held a telephonic
meeting to review the history of the discussions to date with parent and Gambro
and to discuss in detail Gambro's letter. The Board of Directors requested
members of senior management and Goldman Sachs to contact Parent and its
financial advisor to better understand and evaluate the terms set forth in the
letter.
 
    On February 21, 1997, Mr. Lindqvist sent Mr. Thiry another letter
reiterating Gambro's interest in the transaction with the Company. On the same
day, the Company's Board of Directors held a telephonic meeting to discuss the
status of the ongoing discussions with Parent and Gambro. During such telephonic
meeting, the Board of Directors named Mr. Thiry, Ms. Zumwalt and John M. Nehra,
a director of the Company, to a committee to consider the acquisition of the
Company by Gambro and Parent. On February 27, 1997, Mr. Lindqvist sent a letter
to Mr. Thiry and the Company's Board of Directors proposing to acquire only the
Company's renal care business.
 
    On March 7, 1997, the Company's Board of Directors met to discuss Gambro's
offer and the status of ongoing discussions with one additional company
regarding a potential strategic relationship with the Company.
 
    On March 21, 1997, the Company's Board of Directors held a telephonic
meeting to receive a report from Mr. Thiry, Ms. Zumwalt and Mr. Nehra regarding
the February 5, 1997 letter. The Board of Directors also established a Special
Committee consisting of Mr. Nehra and Richard B. Fontaine, a director of the
Company, for the purposes of investigating alternatives available to the Company
regarding VSP, including a possible sale of VSP (the "Special Committee").
 
    On April 2, 1997, representatives of the Company and Goldman Sachs met with
representatives of Parent, Gambro, UBS and Morgan Stanley to discuss a possible
transaction in which Gambro would acquire the Company's dialysis services and
renal care business.
 
    On April 6, 1997, Mr. Nehra, on behalf of the Special Committee, during a
telephone conversation with Messrs. Lilius, Lindqvist and Wahlstrom, indicated
that the Special Committee had met and was interested in moving forward on a
cash tender offer transaction for the Company's Vivra Renal Care business. Mr.
Nehra indicated that it would be appropriate for representatives of Parent to
conduct a due diligence review of the Company's business.
 
    On April 8, 1997, several representatives of Parent and Gambro Healthcare,
together with representatives of Shearman & Sterling, representatives of UBS and
Morgan Stanley met with the Special Committee, together with representatives of
Brobeck, Phleger & Harrison LLP and representatives of Goldman Sachs to organize
legal and operational due diligence and to discuss the process and structure for
the VSP Sale. During April 1997, the Company held ongoing discussions with a
number of companies concerning the VSP Sale.
 
    From April 10, 1997 through April 24, 1997, several representatives of
Parent and Gambro conducted a due diligence review of the Company. These
representatives met at length with the Company's executive officers concerning
the Company's historical and projected financial data. Certain of these meetings
also included a representative of Goldman Sachs. The representatives of Parent
and Gambro also reviewed numerous documents concerning the Company's business,
financial results and financial outlook, as well as the Company's standard
operating policies and procedures and related data.
 
    On April 25, 1997, representatives of Parent and Gambro conducted an
additional due diligence meeting to obtain an update on due diligence matters,
recent financial results, updated financial projections and the status of the
VSP Sale and the interrelationships between the Company and VSP following such
VSP Sale.
 
                                       19
<PAGE>
    On April 22, 1997, representatives of Brobeck, Phleger & Harrison LLP and
Shearman & Sterling met in Washington, D.C. to negotiate the terms of the Merger
Agreement relating to the proposed transaction. On April 24, 1997, Brobeck,
Phleger & Harrison LLP and Shearman & Sterling met again in New York to continue
such negotiations.
 
    On April 26, 1997, the Company's Board of Directors held a telephonic
meeting to discuss the continuing negotiations and current terms of the proposed
transaction with Parent and Gambro. On April 29, 1997, the parties and their
respective representatives met in Chicago to further negotiate the terms and
conditions of the Offer, the Merger and the Merger Agreement.
 
    Representatives of Parent, Gambro and Purchaser and Shearman & Sterling met
with representatives of the Company and Brobek, Phleger & Harrison LLP on May 4
and May 5, 1997 to finalize negotiations of the terms and conditions of the
Offer, the Merger and the Merger Agreement.
 
    On May 4, 1997 and May 5, 1997, the Board of Directors held a special
meeting to consider the acquisition proposal submitted by Purchaser. All of the
Company's directors participated in the meeting. At the meeting, the Board of
Directors reviewed the Merger Agreement, the Offer and the Merger with the
Company's executive officers, legal counsel and representatives of Goldman
Sachs. The Board of Directors heard presentations by its legal counsel with
respect to the terms of the proposed Offer and Merger and by representatives of
Goldman Sachs with respect to the financial terms of the proposed Offer and the
Merger. At the conclusion of their presentation, representatives of Goldman
Sachs delivered their oral opinion to the Board of Directors (subsequently
confirmed in writing) that, as of such date, the consideration proposed to be
received by the holders of the Shares in the Offer and in the Merger is fair to
the holders of the Shares from a financial point of view.
 
    Based upon such discussions, presentations and opinion, the Board of
Directors unanimously (i) approved the Offer, the Merger and the execution of
the Merger Agreement substantially in the form presented to it, and (ii)
recommended that the Company's stockholders accept the Offer and tender their
Shares and approve the Merger and the Merger Agreement. On May 5, 1997,
representatives of the Company, Parent and Purchaser signed the Merger Agreement
and issued a joint press release to such effect.
 
THE MERGER AGREEMENT
 
    A copy of the Merger Agreement is filed as an Exhibit to the Schedule 14D-1
and is incorporated by reference in this Offer to Purchase. Following is a
summary of the Merger Agreement which summary is qualified in its entirety by
reference to the Merger Agreement.
 
    THE OFFER.  The Merger Agreement provides for the commencement of the Offer
as promptly as practicable, but in no event later than five business days after
the initial public announcement of Purchaser's intention to commence the Offer.
The obligation of Purchaser to accept for payment and pay for the Shares
tendered pursuant to the Offer is subject to the satisfaction of (i) the Minimum
Condition prior to the expiration of the Offer and (ii) certain other conditions
described in "Section 15. Certain Conditions of the Offer". Purchaser may waive
any condition to the Offer, increase the price per Share payable in the Offer
and make any other changes to the Offer. However, no change may (i) decrease the
price per Share payable in the Offer, (ii) reduce the maximum number of Shares
to be purchased or (iii) impose conditions to the Offer other than those
described in "Section 15 Certain Conditions of the Offer". The Purchaser may,
without the consent of the Company, (i) extend the Offer beyond the scheduled
Expiration Date (the initial scheduled Expiration Date being June 6, 1997, if,
at the scheduled Expiration Date, any of the conditions to Purchaser's
obligation to accept for payment, and to pay for, the Shares, shall not be
satisfied or waived, (ii) extend the Offer for any period required by any rule,
regulation or interpretation of the Commission or the staff thereof applicable
to the Offer or (iii) extend the Offer for an aggregate period of not more than
10 business days beyond the latest applicable date that would otherwise be
permitted under clause (i) or (ii) of this sentence, if as of such date, all of
the
 
                                       20
<PAGE>
conditions to Purchaser's obligations to accept for payment, and to pay for, the
Shares are satisfied or waived, but the number of Shares validly tendered and
not withdrawn pursuant to the Offer equals 80% or more, but less than 90%, of
the outstanding Shares on a fully diluted basis. However, (A) if, on the initial
scheduled Expiration Date of the Offer, the sole condition remaining unsatisfied
is (1) the failure of the waiting period under the HSR Act to have expired or
been terminated, or (2) the failure to consummate the Specialty Merger
Transaction and such transaction has not been consummated solely due to the
failure of the waiting period under the HSR Act to have expired or been
terminated, then, in either case, the Purchaser is required to extend the Offer
from time to time until five business days after the expiration or termination
of the applicable waiting period under the HSR Act and (B) if the sole condition
remaining unsatisfied on the initial scheduled Expiration Date of the Offer is
the condition described in (f) of "Section 15. Certain Conditions of the Offer",
Purchaser is required, so long as the breach can be cured and the Company is
vigorously attempting to cure such breach, to extend the Offer from time to time
until five business days after such breach is cured provided that Purchaser will
not be required to extend the Offer beyond 35 days after such initial scheduled
Expiration Date.
 
    THE MERGER.  The Merger Agreement provides that, upon the terms and subject
to the conditions thereof and in accordance with Delaware Law, at the Effective
Time, Purchaser will be merged with and into the Company and the Company will
continue as the Surviving Corporation and will become an indirect wholly owned
subsidiary of Parent. Upon consummation of the Merger, each issued and
outstanding Share (other than any Shares held in the treasury of the Company, or
owned by Purchaser, Parent or any direct or indirect wholly owned subsidiary of
Parent or of the Company and any outstanding Shares which are held by
stockholders who have not voted in favor of the Merger or consented thereto in
writing and who shall have demanded properly in writing appraisal for such
Shares in accordance with Delaware Law) will be canceled and converted
automatically into the right to receive an amount equal to the Per Share Amount
(the "Merger Consideration"). Pursuant to the Merger Agreement, each share of
common stock, par value $.01 per share, of Purchaser issued and outstanding
immediately prior to the Effective Time will be converted into and exchanged for
one validly issued, fully paid and nonassessable share of common stock, par
value $.01 per share, of the Surviving Corporation.
 
    CHARTER DOCUMENTS; INITIAL DIRECTORS AND OFFICERS.  The Merger Agreement
provides that, at the Effective Time, the Certificate of Incorporation of
Purchaser, as in effect immediately prior to the Effective Time, will be the
Certificate of Incorporation of the Surviving Corporation; PROVIDED, HOWEVER,
that Article I of the Certificate of Incorporation of the Surviving Corporation
will be amended to read as follows: "The name of the corporation is Vivra
Incorporated." The Merger Agreement also provides that the By-laws of Purchaser,
as in effect immediately prior to the Effective Time, will be the By-laws of the
Surviving Corporation. Pursuant to the Merger Agreement, the directors of
Purchaser immediately prior to the Effective Time will be the initial directors
of the Surviving Corporation and the officers of the Purchaser immediately prior
to the Effective Time will be the initial officers of the Surviving Corporation.
 
    STOCKHOLDERS MEETING.  The Merger Agreement provides that, if required by
applicable law in order to consummate the Merger, the Company will, in
accordance with applicable law and its Certificate of Incorporation and By-Laws,
(i) convene and hold an annual or special meeting of its stockholders (the
"Company Stockholders Meeting") for the purpose of considering and taking action
on the Merger Agreement and the transactions contemplated thereby, and (ii)
except if the Board determines in good faith an alternative action to be
necessary in accordance with its fiduciary duties to the Company's stockholders
under applicable law as advised by outside legal counsel, use its reasonable
efforts to approve and adopt the Merger Agreement and the transactions
contemplated thereby. Parent and Purchaser will cause all Shares owned by them
and their subsidiaries to be voted in favor of the approval and adoption of the
Merger Agreement and the transactions contemplated thereby. If the Minimum
Condition is satisfied, Purchaser will have sufficient voting power to cause the
approval and adoption of the Merger without the affirmative vote of any other
stockholder. Under Delaware Law, if Purchaser
 
                                       21
<PAGE>
acquires at least 90% of the outstanding Shares, Purchaser will be able to
approve the Merger without a vote of the Company's stockholders.
 
    FILINGS.  The Merger Agreement provides that the Company will, as soon as
reasonably practicable after the consummation of the Offer and if required by
applicable law, prepare and file the Proxy Statement with the Commission, and
will use all reasonable efforts to have the Proxy Statement cleared by the
Commission. The Company has agreed that, except if the Board determines in good
faith an alternative action to be necessary in accordance with its fiduciary
duties to the Company's stockholders under applicable law as advised by outside
legal counsel, the Proxy Statement will contain the unanimous recommendation of
the Board that the stockholders of the Company approve the Merger Agreement and
the transactions contemplated thereby.
 
    CONDUCT OF DIALYSIS BUSINESS.  Pursuant to the Merger Agreement, the Company
has covenanted and agreed that, between the date of the Merger Agreement and the
Effective Time, unless Parent or Purchaser will otherwise agree in writing, the
Company's dialysis, renal care or nephrologist practice management business or
the Company's business of contracting with payors on behalf of nephrologists
(the "Dialysis Business") will be conducted only in, and the Company and the
subsidiaries of the Company engaged in the Dialysis Business (the "Dialysis
Subsidiaries") will not take any action with respect to the Dialysis Business
except in the ordinary course of the Dialysis Business; and the Company and the
Dialysis Subsidiaries will use all reasonable commercial efforts to preserve
substantially intact the business organization of the Dialysis Business, to keep
available the services of the current officers, employees and consultants of the
Dialysis Business and to preserve the current relationships of the Company and
the Dialysis Subsidiaries with physicians, payors and other persons with which
the Company or any Dialysis Subsidiary has significant business relations. By
way of amplification and not limitation, the Merger Agreement provides that

    shares of such capital stock, or any other ownership interest of the Company
    or any Dialysis Subsidiary (except for the issuance of certain Shares
    pursuant to outstanding options and Shares issuable upon conversion of the
    Convertible Notes) or (ii) any assets of the Company or any Dialysis
    Subsidiary, except as contemplated by the Specialty Merger Transaction or in
    the ordinary course of the Dialysis Business;
 
       (iii) declare, set aside, make or pay any dividend or other distribution,
    payable in cash, stock, property or otherwise, with respect to any of its
    capital stock;

    stock, or purchase or otherwise acquire, directly or indirectly, any of its
    capital stock or any capital stock of any other Subsidiary;
 
        (v) acquire (including, without limitation, by merger, consolidation, or
    acquisition of stock or assets) any interest in any corporation,
    partnership, other business organization or any division thereof or any
    material amount of assets, or authorize any capital expenditures, other than
    acquisitions or capital expenditures in the ordinary course of the Dialysis
    Business which, in the aggregate, do not exceed $10,000,000 in each of May

    state, local or foreign income tax liability;
 
       (xi) settle any litigation, suit, claim, action, proceeding or

    CONDUCT OF SPECIALTY BUSINESS.  The Merger Agreement provides that from the
date thereof until the earlier of the consummation of the Specialty Merger
Transaction and the termination of the Merger Agreement pursuant to its terms,

Specialty Subsidiary of cash, cash equivalents, marketable securities or any
other asset and Specialty Partners and the Specialty Subsidiaries shall not make
any contribution, payment or other transfer to the Company or any Dialysis
Subsidiary of cash, cash equivalents, marketable securities or any other asset.
 
    DIRECTORS.  The Merger Agreement provides that, promptly upon the purchase
by Purchaser of the Shares pursuant to the Offer, and from time to time
thereafter, Purchaser will be entitled to designate such number of directors,
rounded up to the next whole number, on the Board as will give Purchaser
representation on the Board equal to the product of the total number of
directors on the Board (giving effect to the directors elected pursuant to this
sentence) multiplied by the percentage that the aggregate number of Shares
beneficially owned by Purchaser or any of its affiliates following such purchase
bears to the number of Shares outstanding, and the Company will, at such time,
promptly take all actions necessary to cause Purchaser's designees to be elected
as directors of the Company, including increasing the size of the Board or
securing the resignation of incumbent directors or both. At such times, the
Company will, upon written request to Purchaser, use its reasonable efforts to
cause persons designated by Purchaser to constitute the same percentage as
persons designated by Purchaser will constitute of the Board of (i) each
committee of the Board, (ii) the board of directors of each domestic Dialysis
Subsidiary and (iii) each committee of each such board, to the extent permitted
by applicable law. Until the earlier of (i) the time Purchaser acquires a

                                       23
<PAGE>
(ii) the Effective Time, the Company is required to use its reasonable efforts
to ensure that all the members of the Board and each committee of the Board and
such boards and committees of the domestic Dialysis Subsidiaries of the Company
as of the date of the Merger Agreement who are not employees of the Company will
remain members of the Board and of such boards and committees, except for the
members not standing for re-election at the Company's 1997 annual meeting of
stockholders.
 
    Pursuant to the Merger Agreement, after the election of designees of
Purchaser pursuant to the preceding paragraph and prior to the Effective Time,
any amendment of the Merger Agreement or the Certificate of Incorporation or
By-laws of the Company, any termination of the Merger Agreement by the Company,
any extension by the Company of the time for the performance of any of the
obligations or other acts of Parent or Purchaser or waiver of any of the
Company's rights hereunder will require the concurrence of a majority of the
directors of the Company then in office who neither were designated by Purchaser
nor are employees of the Company.
 
    NO SOLICITATION.  The Company has agreed that it will, and will direct and
use all reasonable efforts to cause its officers, directors, employees,
representatives and agents to immediately cease any discussions or negotiations
with any parties that may be ongoing with respect to any "Acquisition Proposal"
(as defined below). Except with respect to the Specialty Merger Transaction, the
Company will not, nor will it permit any of its subsidiaries to, nor will it
authorize or permit any officer, director or employee of, or any investment
banker, accountant, attorney or other advisor or representative of, the Company
or any of its subsidiaries to, directly or indirectly, (i) solicit or initiate,
or knowingly encourage the submission of, any Acquisition Proposal or (ii)
participate in any discussions or negotiations regarding, or furnish to any
person any information with respect to, or take any other action to facilitate
the making of any proposal that constitutes, or may reasonably be expected to
lead to, an Acquisition Proposal; PROVIDED, HOWEVER, that if and to the extent,
prior to the acceptance for payment of Shares pursuant to the Offer, the Board
determines in good faith it is necessary to do so in accordance with its
fiduciary duties to the Company's stockholders under applicable law as advised
by outside legal counsel, the Company may, in response to an unsolicited written
Acquisition Proposal, and subject to compliance with the notice requirements
described below, (x) furnish information with respect to the Company to any
persons pursuant to a customary confidentiality agreement on terms no less
favorable to the Company than those contained in the confidentiality agreement
dated October 7, 1996 between Parent and the Company and (y) participate in
discussions regarding and negotiate with respect to such Acquisition Proposal.
 
    For purposes of the Merger Agreement, "ACQUISITION PROPOSAL" means any bona
fide proposal or offer from any person relating to any direct or indirect
acquisition or purchase of all or a substantial part of the assets of the
Company or any of the Dialysis Subsidiaries or of over 20% of any class of
equity securities of the Company or any of the Dialysis Subsidiaries, any tender
offer or exchange offer that if consummated would result in any person
beneficially owning 20% or more of any class of equity securities of the Company
or any of the Dialysis Subsidiaries, any merger, consolidation, business
combination, sale of all or substantially all of the assets, recapitalization,
liquidation, dissolution or similar transaction involving the Company or any of
the Dialysis Subsidiaries, other than the transactions contemplated by the
Merger Agreement and the Specialty Merger Transaction, or any other transaction
the consummation of which would reasonably be expected to impede, interfere
with, prevent or materially delay the Offer or the Merger or which would
reasonably be expected to dilute materially the benefits to Parent of the
transactions contemplated by the Offer and the Merger.
 
    The Merger Agreement also provides that neither the Board nor any committee
thereof shall (i) withdraw or modify, or propose to withdraw or modify, in a
manner adverse to the Parent, the approval or recommendation by the Board or any
such committee of the Offer, the Merger Agreement or the Merger, (ii) approve or
recommend, or propose to approve or recommend, any Acquisition Proposal or (iii)
enter into any agreement with respect to any Acquisition Proposal.
Notwithstanding the foregoing, in the event prior to the time of acceptance for
payment of Shares pursuant to the Offer the Board
 
                                       24
<PAGE>
determines in good faith that it is necessary to do so in accordance with its
fiduciary duties to the Company's stockholders under applicable law as advised
by outside legal counsel, the Board may (x) withdraw or modify its approval or
recommendation of the Offer, the Merger and the Merger Agreement in order to
enter into a definitive agreement with respect to a Superior Proposal (as
defined below) and may terminate the Merger Agreement pursuant to the
termination provisions described below (and concurrently with or after such
termination may cause the Company to enter into any agreement with respect to
any Superior Proposal). For purposes of the Merger Agreement, a "SUPERIOR
PROPOSAL" means any bona fide proposal made by a third party to acquire,
directly or indirectly, for consideration consisting of cash and/or securities,
more than 50% of the combined voting power of the Shares then outstanding or all
or substantially all of the assets of the Company and otherwise on terms which
the Board determines in its good faith judgment (based on the advice of a
financial advisor of nationally recognized reputation) to be more favorable to
the Company's stockholders than the Offer and the Merger and for which
financing, to the extent required, is then committed.
 
    The Merger Agreement provides that the Company will promptly advise Parent
orally and in writing of any request for information or of any Acquisition
Proposal, the material terms and conditions of such request or Acquisition
Proposal and the identity of the person making such request or Acquisition
Proposal.
 
    DIRECTORS' AND OFFICERS' INDEMNIFICATION.  The Merger Agreement requires
that the Certificate of Incorporation of the Surviving Corporation contain
provisions no less favorable with respect to indemnification than are set forth
in Article Eight of the Certificate of Incorporation of the Company, which
provisions will not be amended, repealed or otherwise modified for six years
after the Effective Time in any manner that would affect adversely the rights of
individuals who at the Effective Time were directors, officers, employees,
fiduciaries or agents of the Company, unless such modification is required by
law. To the extent that the obligations under such provisions are not fully
performed by the Surviving Corporation, Parent has agreed to perform fully the
obligations thereunder for the remaining period.
 
    Parent or the Surviving Corporation will use its best efforts to maintain in
effect for a period not less than six years after the Effective Time the current
directors' and officers' liability insurance policies maintained by the Company
(provided that Parent or the Surviving Corporation may substitute therefor
policies of at least the same coverage containing terms and conditions which are
not materially less favorable to such directors and officers) with respect to
matters occurring prior to the Effective Time; PROVIDED, HOWEVER, that if the
existing policies expire, are terminated or cancelled during such period, Parent
or Surviving Corporation will use its best efforts to obtain substantially
similar policies. Notwithstanding the foregoing, the Merger Agreement provides
that in no event will Parent or the Surviving Corporation be required to pay
more than an amount per year equal to 150% of current annual premiums paid by
the Company for such insurance. If the Parent or the Surviving Corporation is
not able to obtain the amount of required insurance for such aggregate premium,
the Merger Agreement requires Parent or the Surviving Corporation to obtain as
much insurance as can be obtained for an annual premium of 150% of the Company's
current annual premiums.
 
    OPTIONS PLANS.  The Merger Agreement provides that immediately prior to the
Effective Time, the Company will take all such actions as shall be necessary to
cause all stock options (and any related alternative rights) to purchase shares
(the "EMPLOYEE STOCK OPTIONS") granted under the Company's stock option plans
which are outstanding immediately prior to the Effective Time (whether or not
then presently exercisable or vested), to be cancelled. In exchange for the
cancellation of such Employee Stock Option, the holder thereof will be entitled
to receive from the Surviving Corporation an amount in cash equal to the product
of the difference between the Per Share Amount and the per share exercise price
of such Employee Stock Option, and the number of shares of Company Common Stock
covered by such Employee Stock Option. All payments in respect of Employee Stock
Options will be made after the Effective Time and not later than 30 days
following the Effective Time, subject to the Company's collection of all
applicable withholding taxes. The Merger Agreement also provides that all
restricted
 
                                       25
<PAGE>
stock under the Company's 1989 Stock Incentive Plan will be vested, and any
restrictions attached to such stock pursuant to such plan will lapse,
immediately prior to the Effective Time.
 
    In addition, the Merger Agreement states that the Company Stock Option Plans
will terminate as of the Effective Time and thereafter the only rights of
participants therein will be the right to receive the consideration set forth in
the previous paragraph. Prior to the Effective Time, the Company will cause each
holder of an outstanding Employee Stock Option to consent to the cancellation of
the Employee Stock Options held by such holder in consideration for the payment
provided herein, and will take such other action as may be necessary to carry
out the terms of the foregoing.
 
    RETENTION ARRANGEMENT.  The Merger Agreement provides that, following the
Effective Time, the Company will maintain a retention bonus and deferred
compensation arrangement (the "Retention Arrangement") with substantially the
terms and conditions set forth therein. As set forth in the Merger Agreement,
the Retention Arrangement will provide certain executives and key employees of
the Company with bonuses which will be payable in installments of 20% one month
following the Effective Time and 40% on each of the first two anniversaries of
the Effective Time. The Retention Arrangement will permit participants to defer
all or a specified percentage of each installment of the bonus. Amounts so
deferred will be credited to a deferred compensation account established by the
Company on its books and records for each participant, credited with notional
interest and distributed to the participant commencing on the later to occur of
the participant's termination of employment with the Company or attainment of
age 60. As a condition to the receipt of payments pursuant to the Retention
Arrangement, participants will be required to enter into certain
non-competition, non-solicitation and non-disclosure agreements with the
Company.
 
    The Retention Arrangement is subject to the consummation of the Merger, and
the Company will have no payment obligations under the Retention Arrangement in
the event that the Merger is not consummated.
 
    CONVERTIBLE SUBORDINATED NOTES.  Pursuant to the Merger Agreement, prior to
the Effective Time, the Company will, in accordance with the terms of the
Convertible Note Indenture, execute and deliver to the Trustee a supplemental
indenture providing that, after the Effective Time, each $1,000 principal amount
of the Convertible Notes will be convertible into an amount of cash equal to the
price payable per Share in the Offer multiplied by 26.88. The Company also
agreed that it will offer to repurchase the Convertible Notes at the option of
the holders thereof and will consummate such repurchase, in each case in
accordance with the Indenture.
 
    REPRESENTATIONS AND WARRANTIES.  The Merger Agreement contains various
customary representations and warranties of the parties thereto including
representations by the Company as to the absence of certain changes or events
concerning the Company's corporate organization and qualification,
capitalization, authority, filings with the Commission and other governmental
authorities, financial statements, litigation, employee benefit matters,
intellectual property, real property, taxes, insurance, environmental matters,
material contracts, compliance with law, and Board approval of amendments to the
Company's Amended and Restated Rights Agreement dated as of February 13, 1996
between the Company and the First National Bank of Boston.
 
    CONDITIONS TO CONSUMMATION OF THE MERGER.  The Merger Agreement provides
that the respective obligations of each party to effect the Merger is subject to
the following conditions: (i) the Merger Agreement, the Merger and the
transactions contemplated thereby will have been approved and adopted by the
affirmative vote of the stockholders of the Company to the extent required by
Delaware Law and the Certificate of Incorporation of the Company; (ii) any
waiting period (and any extension thereof) applicable to the consummation of the
Merger under the HSR Act will have expired or been terminated;
 
                                       26
<PAGE>
(iii) no foreign, United States or state governmental authority or other agency
or commission or foreign, United States or state court of competent jurisdiction
shall have enacted, issued, promulgated, enforced or entered any law, rule,
regulation, executive order, decree, injunction or other order (whether
temporary, preliminary or permanent) which is then in effect and has the effect
of making the acquisition of Shares by Parent or Purchaser or any affiliate of
either of them illegal or otherwise restricting, preventing or prohibiting
consummation of the transactions by the Merger Agreement or the Specialty Merger
Transaction; and (iv) Purchaser or its permitted assignee shall have purchased
all Shares validly tendered and not withdrawn pursuant to the Offer; PROVIDED,
HOWEVER, that this condition shall not be applicable to the obligations of
Parent or Purchaser if, in breach of the Merger Agreement or the terms of the
Offer, Purchaser fails to purchase any Shares validly tendered and not withdrawn
pursuant to the Offer.
 
    TERMINATION.  The Merger Agreement may be terminated at any time prior to
the Effective Time by: (i) mutual written consent of Parent, Purchaser and the
Company duly authorized by their respective Boards of Directors; or (ii) either
Parent, Purchaser or the Company if (a) the Effective Time will not have
occurred on or before July 31, 1997; PROVIDED, HOWEVER, that if the waiting
period under the HSR Act shall not have expired or been terminated as of such
date or any Governmental Authority shall have caused to be issued as of such
date a temporary restraining order or a preliminary injunction prohibiting the
consummation of the Offer or the Merger and each of the parties to the Merger
Agreement are seeking the termination of such waiting period or contesting such
temporary restraining order or preliminary injunction, as the case may be, such
date shall be extended to the earlier of the date of expiration or termination
of such waiting period or the lifting of such injunction or order or October 31,
1997; PROVIDED, FURTHER, HOWEVER, that the right to terminate the Merger
Agreement pursuant to this sentence will not be available (1) to any party whose
failure to fulfill any obligation under the Merger Agreement has been the cause
of, or resulted in, the failure of the Effective Time to occur on or before such
date or (2) after Purchaser shall have purchased the Shares pursuant to the
Offer, or (b) any court of competent jurisdiction in the United States or the
Kingdom of Sweden or other governmental authority in the United States or the
Kingdom of Sweden will have issued an order, decree, ruling or taken any other
action restraining, enjoining or otherwise prohibiting the Merger and such
order, decree, ruling or other action will have become final and nonappealable;
or (iii) Parent if due to an occurrence or circumstance, other than a breach by
Parent or Purchaser of their obligations under the Merger Agreement, that would
result in a failure to satisfy any condition described in "Section 15. Certain
Conditions of the Offer" (which failure cannot be cured or, if capable of being
cured, has not been cured in all material respects within 30 days after notice
to the Company of such occurrence or circumstance), Purchaser will have
terminated the Offer without having accepted any Shares for payment thereunder;
or (iv) the Company, upon approval of the Board, if (a) due to an occurrence or
circumstance that would result in a failure to satisfy any of the conditions in
"Section 15. Certain Conditions of the Offer", Purchaser will have terminated
the Offer without having accepted any Shares for payment thereunder or (b) prior
to the purchase of Shares pursuant to the Offer, in order to enter into a

faith that it is necessary to do so in accordance with its fiduciary duties to
the Company's stockholders under applicable law as advised by outside legal
counsel; PROVIDED, HOWEVER, that any termination of the Merger Agreement
pursuant to this clause (iv)(b) will not be effective until the Company has made
full payment of all amounts as set forth in "-- Fees and Expenses" below, or (c)
if Parent or Purchaser will have failed to commence the Offer within five
business days following the date of the initial public announcement of the Offer
other than as a result of an occurrence or circumstance that would result in a
failure to satisfy any of the conditions described in "Section 15. Certain
Conditions of the Offer", or (d) if Parent or Purchaser shall have breached any
of their respective representations, warranties, covenants or other agreements
contained in the Merger Agreement in a manner that materially adversely affects
Parent's ability to consummate the Offer and the Merger and which cannot be
cured or, if capable of being cured, has not been cured in all material respects
within 30 days after notice to Parent of such occurrence or circumstance.
 
                                       27
<PAGE>
    FEES AND EXPENSES.  The Merger Agreement provides that in the event that (i)
the Merger Agreement is terminated under clause (iv)(b) of the preceding
paragraph; or (ii) (a) an Acquisition Proposal is commenced, publicly proposed,
publicly disclosed or communicated to the Company or any representative or agent
thereof after the date of the Merger Agreement and prior to the date of its
termination, (b) the Merger Agreement is thereafter terminated pursuant to
clause (ii), (iii) or (iv)(a) of the preceding paragraph, and (c) within 12
months following such termination, an Acquisition Proposal is consummated or the
Company enters into an agreement relating thereto; then, in any such event, the
Company will pay Parent promptly a fee of $50,000,000 (the "Fee"), which amount
will be payable in immediately available funds, plus all Expenses (as defined
below); PROVIDED, HOWEVER, that no Fee shall be payable under clause (ii) of
this paragraph if, at the time of termination, Parent or Purchaser is in
material breach of their respective material covenants and agreements and their
respective representations and warranties, in each case contained in the Merger
Agreement.
 
    If the Merger Agreement is terminated for any reason whatsoever and neither
Parent nor Purchaser is in material breach of their respective material
covenants and agreements or their respective representations and warranties, the
Company will, whether or not any payment is made pursuant to the preceding
paragraph, reimburse each of Parent, Purchaser and their respective stockholders
and affiliates for all actual and documented out-of-pocket expenses and fees up
to $4,000,000 in the aggregate (including, without limitation, fees and expenses
payable to all banks, investment banking firms, other financial institutions and
other persons and their respective agents and counsel, for arranging, committing
to provide or providing any financing for or the structuring of the transactions
contemplated by the Merger Agreement and the Specialty Merger Transaction and
all fees of counsel, accountants, experts and consultants to Parent, Purchaser
and their respective stockholders and affiliates, and all printing and
advertising expenses) actually incurred or accrued by either of them or on their
behalf in connection with the Offer, Merger and Specialty Merger Transactions,
including, without limitation, the financing thereof, and actually incurred or
accrued by banks, investment banking firms, other financial institutions and
other persons and assumed by Parent, Purchaser or their respective stockholders
or affiliates in connection with the negotiation, preparation, execution and
performance of the Merger Agreement, the structuring and financing of the
transactions contemplated by the Merger Agreement and any financing commitments
or agreements relating thereto (all of the foregoing being referred to herein
collectively as the "Expenses").
 
    Except as set forth in the above paragraph, all costs and expenses incurred
in connection with the Merger Agreement, the transactions contemplated thereby
and the Specialty Merger Transaction will be paid by the party incurring such
expenses, whether or not such transactions are consummated.
 
THE SPECIALTY MERGER AGREEMENT
 
    The following is a summary of certain provisions of the Specialty Merger
Agreement and is qualified in its entirety by reference to the Specialty Merger
Agreement which has been filed as Exhibit (c)(2) to this Schedule 14D-1 and is
incorporated herein by reference in its entirety.
 
    Simultaneously with the execution of the Merger Agreement, the Company
entered into the Specialty Merger Agreement, pursuant to which the Company will
sell the Company's interests in Specialty Partners and in VHI to the VSP
Purchasers. Both Specialty Partners and VHI are engaged in the Company's
Specialty Business. Pursuant to the Specialty Merger Agreement, the gross
consideration allocated between Specialty Partners and VHI will be $84,312,500
(the "Gross Consideration"). Of this amount, the Company expects to receive sale
proceeds of approximately $79,387,500. Assuming both a pre-tax gain to the
Company of approximately $5,400,000 and an income tax rate of 41 percent, the
Company will incur a tax liability of approximately $2,200,000 in connection
with the Specialty Merger Transaction. The net after-tax proceeds of
approximately $77,200,00 represents approximately $1.72 per Share on a fully
diluted basis. The receipt by the Company of not less than $76,900,000 of such
net after-tax proceeds is a condition to the purchase of the Shares in the
Offer.
 
                                       28
<PAGE>
    Pursuant to the Specialty Merger Agreement, (i) VSP Merger Sub will be
merged with and into Specialty Partners, with Specialty Partners as the
surviving corporation, and (ii) VSP Purchaser II will obtain a majority interest
in VHI. The VSP Purchasers are corporations organized by certain private equity
investment funds for the purpose of acquiring the Company's interests in
Specialty Partners and VHI. Mr. Thiry, the Company's President and Chief
Executive Officer and Ms. Zumwalt, the Company's Chief Financial Officer, will
become the President and Chief Executive Officer and Chief Financial Officer,
respectively, of Specialty Partners following the completion of the transactions
contemplated by the Merger Agreement. Further, each of Mr. Thiry and Ms. Zumwalt
intends to make an equity investment in the VSP Purchasers.
 
    Prior to consummation of the Specialty Merger Transaction, the Company and
Specialty Partners have agreed to, among other things: (a) conduct Specialty
Partners' business in the ordinary course, including preserving existing
relationships with customers and suppliers and maintaining existing material
contracts to which Specialty Partners is a party; (b) cause certain subsidiaries
of Specialty Partners (namely, Vivra Asthma Allergy Careamerica, Inc., Vivra
Heart Services, Inc., Vivra ENT, Inc., Vivra Health Advantage, Inc., Vivra
Orthopaedics, Inc. and Vivra OB-GYN Services, Inc.) to merge with and into
Specialty Partners; (c) transfer and assign certain assets and liabilities of
the Company to Specialty Partners; and (d) enter into an agreement pursuant to
which the Company will assign to Specialty Partners all of the Company's rights,
title and interest in and to the "Vivra" trademark, and other trademarks of the
Company incorporating the word "Vivra"; PROVIDED, HOWEVER, that simultaneously
with the closing of the Specialty Merger Transaction (the "VSP Closing"),
Specialty Partners will license to the Company use of the name "Vivra Renal
Care" for nine months following the VSP Closing and use of the name "Vivra" for
three months following the VSP Closing (collectively, the "VSP Covenants").
 
    The obligations of the Purchasers to consummate the Specialty Merger
Transaction are subject to the satisfaction or waiver of certain conditions,
including: (a) that the representations and warranties made by Specialty
Partners and the Company will be true and correct as of the date of the VSP
Closing; (b) the VSP Covenants will have been performed by the Company and
Specialty Partners; (c) any waiting period (or any extension thereof) under the
HSR Act will have expired or been terminated; (d) a noncompetition agreement
between Specialty Partners and Parent will have been executed; (e) the Services
Agreement between Specialty Partners and the Company pursuant to which each of
the parties thereto provides certain administrative services to the other shall
be in full force and effect and there shall have been no breach thereunder; (f)
there will have been no change, circumstance or occurrence since the date of the
Specialty Merger Agreement which would have a material adverse effect on
Specialty Partners' business, operations, properties or condition; and (g)
Purchaser shall have advised the Company that it will purchase the Shares in the
Offer or the Purchaser or any other person or entity shall have acquired either
the (x) greater than 50% of the Shares or (y) all or substantially all of the
assets of the Company.
 
    The Specialty Merger Agreement provides that, for a period of five years
from the VSP Closing, VSP Purchaser and Specialty Partners will indemnify the
Company from claims arising from the operation of the business of Specialty
Partners and the Company will indemnify VSP Purchaser and Specialty Partners
from claims arising from the operation of the business of the Company.
 
    The Specialty Merger Agreement also provides that if the VSP Closing has not
occurred by June 30, 1997 solely as a result of the Offer not being consummated,
the VSP Purchasers may elect to consummate an alternative transaction pursuant
to which the VSP Purchasers would acquire 65% of the Company's interest in
Specialty Partners and 65% of the Company's interest in VHI, in exchange for 65%
of the Gross Consideration.
 
    12. PURPOSE OF THE OFFER; PLANS FOR THE COMPANY AFTER THE OFFER AND THE
MERGER.
 
    PURPOSE OF THE OFFER.  The purpose of the Offer and the Merger is for Parent
to acquire control of, and the entire equity interest in, the Company. The
purpose of the Merger is for Parent to acquire all Shares not purchased pursuant
to the Offer. Upon consummation of the Merger, the Company will
 
                                       29
<PAGE>
become an indirect wholly owned subsidiary of Parent. The Offer is being made
pursuant to the Merger Agreement.
 
    PLANS FOR MERGER CONSUMMATION.  Under Delaware Law, the approval of the
Board and the affirmative vote of the holders of a majority of the outstanding
Shares is required to approve and adopt the Merger Agreement and the
transactions contemplated thereby, including the Merger. The Board of Directors
of the Company has unanimously approved and adopted the Merger Agreement and the
transactions contemplated thereby, and, unless the Merger is consummated
pursuant to the short-form merger provisions under Delaware Law described below,
the only remaining required corporate action of the Company is the approval and
adoption of the Merger Agreement and the transactions contemplated thereby by
the affirmative vote of the holders of a majority of the Shares. Accordingly, if
the Minimum Condition is satisfied, Purchaser will have sufficient voting power
to cause the approval and adoption of the Merger Agreement and the transactions
contemplated thereby without the affirmative vote of any other stockholder.
 
    In the Merger Agreement, the Company has agreed to take all action necessary
to convene a meeting of its stockholders as soon as practicable after the
consummation of the Offer for the purpose of considering and taking action on
the Merger Agreement and the transactions contemplated thereby, if such action
is required by Delaware Law.
 
    If Purchaser purchases Shares pursuant to the Offer, the Merger Agreement
provides that Purchaser will be entitled to designate representatives to serve
on the Board in proportion to Purchaser's ownership of Shares following such
purchase. See "Section 11. Background of the Offer; Contacts with the Company;
the Merger Agreement and the Specialty Merger Agreement". Purchaser expects that
such representation would permit Purchaser to exert substantial influence over
the Company's conduct of its business and operations.
 
    Under Delaware Law, if Purchaser acquires, pursuant to the Offer or
otherwise, at least 90% of the outstanding Shares, Purchaser will be able to
approve the Merger without a vote of the Company's stockholders. In such event,
Parent, Purchaser and the Company have agreed in the Merger Agreement to take,
at the request of Purchaser, all necessary and appropriate action to cause the
Merger to become effective as soon as reasonably practicable after such
acquisition, without a meeting of the Company's stockholders. If, however,
Purchaser does not acquire at least 90% of the outstanding Shares pursuant to
the Offer or otherwise and a vote of the Company's stockholders is required
under Delaware Law, a significantly longer period of time would be required to
effect the Merger.
 
    APPRAISAL RIGHTS.  No appraisal rights are available in connection with the
Offer. However, if the Merger is consummated, stockholders will have certain
rights under Delaware Law to dissent and demand appraisal of, and to receive
payment in cash of the fair value of, their Shares. Such rights to dissent, if
the statutory procedures are complied with, could lead to a judicial
determination of the fair value of the Shares, as of the day prior to the date
on which the stockholders' vote was taken approving the Merger or similar
business combination (excluding any element of value arising from the
accomplishment or expectation of the Merger), required to be paid in cash to
such dissenting holders for their Shares. In addition, such dissenting
stockholders would be entitled to receive payment of a fair rate of interest
from the date of consummation of the Merger on the amount determined to be the
fair value of their Shares. In determining the fair value of the Shares, the
court is required to take into account all relevant factors. Accordingly, such
determination could be based upon considerations other than, or in addition to,
the market value of the Shares, including, among other things, asset values and
earning capacity. In WEINBERGER V. UOP, INC., the Delaware Supreme Court stated,
among other things, that "proof of value by any techniques or methods which are
generally considered acceptable in the financial community and otherwise
admissible in court" should be considered in an appraisal proceeding. Therefore,
the value so determined in any appraisal proceeding could be the same, more or
less than the purchase price per Share in the Offer or the Merger Consideration.
 
                                       30
<PAGE>
    In addition, several decisions by Delaware courts have held that, in certain
circumstances, a controlling stockholder of a company involved in a merger has a
fiduciary duty to other stockholders which requires that the merger be fair to
such other stockholders. In determining whether a merger is fair to minority
stockholders, Delaware courts have considered, among other things, the type and
amount of consideration to be received by the stockholders and whether there was
fair dealing among the parties. The Delaware Supreme Court stated in WEINBERGER
and RABKIN V. PHILIP A. HUNT CHEMICAL CORP. that the remedy ordinarily available
to minority stockholders in a cash-out merger is the right to appraisal
described above. However, a damages remedy or injunctive relief may be available
if a merger is found to be the product of procedural unfairness, including
fraud, misrepresentation or other misconduct.
 
    RULE 13E-3.   The Commission has adopted Rule 13e-3 under the Exchange Act
which is applicable to certain "going private" transactions and which may under
certain circumstances be applicable to the Merger or another business
combination following the purchase of Shares pursuant to the Offer in which
Purchaser seeks to acquire the remaining Shares not held by it. Purchaser
believes, however, that Rule 13e-3 will not be applicable to the Merger. Rule
13e-3 requires, among other things, that certain financial information
concerning the Company and certain information relating to the fairness of the
proposed transaction and the consideration offered to minority stockholders in
such transaction, be filed with the Commission and disclosed to stockholders
prior to consummation of the transaction.
 
    PLANS FOR THE COMPANY.   It is expected that, initially following the
Merger, the business and operations of the Company will, except as set forth in
this Offer to Purchase, be continued by the Company substantially as they are
currently being conducted. Parent will continue to evaluate the business and
operations of the Company during the pendency of the Offer and after the
consummation of the Offer and the Merger, and will take such actions as it deems
appropriate under the circumstances then existing. Parent intends to seek
additional information about the Company during this period. Thereafter, Parent
intends to review such information as part of a comprehensive review of the
Company's business, operations, capitalization and management with a view to
optimizing exploitation of the Company's potential in conjunction with Parent's
businesses. It is expected that the business and operations of the Company would
be integrated with the dialysis and renal care operations of Gambro Healthcare.
 
    Except as indicated in this Offer to Purchase, Parent does not have any
present plans or proposals which relate to or would result in an extraordinary
corporate transaction, such as a merger, reorganization or liquidation,
involving the Company or any Subsidiary, a sale or transfer of a material amount
of assets of the Company or any Subsidiary or any material change in the
Company's capitalization or dividend policy or any other material changes in the
Company's corporate structure or business, or the composition of the Board or
the Company's management.
 
    13. DIVIDENDS AND DISTRIBUTIONS. The Merger Agreement provides that the
Company shall not, between the date of the Merger Agreement and the Effective
Time, without the prior written consent of Parent, (a) issue, sell, pledge,
dispose of, grant, encumber, or authorize the issuance, sale, pledge,
disposition, grant or encumbrance of any shares of capital stock of any class of
the Company or any Dialysis Subsidiary, or any options, warrants, convertible
securities or other rights of any kind to acquire any shares of such capital
stock, or any other ownership interest (including, without limitation, any
phantom interest), of the Company or any Dialysis Subsidiary (except for the
issuance of Shares issuable pursuant to employee stock options outstanding on
the date hereof and Shares issuable pursuant to the conversion of the
Convertible Notes) or (b) reclassify, combine, split, subdivide or redeem,
purchase or otherwise acquire, directly or indirectly, any of its capital stock.
See "Section 11. Background of the Offer; Contacts with the Company; the Merger
Agreement and the Specialty Merger Agreement". If, however, the Company should,
during the pendency of the Offer, (i) split, combine or otherwise change the
Shares or its capitalization, (ii) acquire or otherwise cause a reduction in the
number of outstanding Shares or (iii) issue or sell any additional Shares,
shares of any other class or series of capital stock, other voting securities or
any securities convertible into, or options, rights, or warrants, conditional or
otherwise, to
 
                                       31
<PAGE>
acquire, any of the foregoing, then, without prejudice to Purchaser's rights
under "Section 15. Certain Conditions of the Offer", Purchaser may (subject to
the provisions of the Merger Agreement) make such adjustments to the purchase
price and other terms of the Offer (including the number and type of securities
to be purchased) as it deems appropriate to reflect such split, combination or
other change.
 
    If, on or after May 5, 1997, the Company should declare or pay any dividend
on the Shares or make any other distribution (including the issuance of
additional shares of capital stock pursuant to a stock dividend or stock split,
the issuance of other securities or the issuance of rights for the purchase of
any securities) with respect to the Shares that is payable or distributable to
stockholders of record on a date prior to the transfer to the name of Purchaser
or its nominee or transferee on the Company's stock transfer records of the
Shares purchased pursuant to the Offer, then, without prejudice to Purchaser's
rights under "Section 15. Certain Conditions of the Offer", (i) the Per Share
Amount payable by Purchaser pursuant to the Offer will be reduced (subject to
the Merger Agreement) to the extent any such dividend or distribution is payable
in cash and (ii) any non-cash dividend, distribution or right shall be received
and held by the tendering stockholder for the account of Purchaser and will be
required to be promptly remitted and transferred by each tendering stockholder
to the Depositary for the account of Purchaser, accompanied by appropriate
documentation of transfer. Pending such remittance and subject to applicable
law, Purchaser will be entitled to all the rights and privileges as owner of any
such non-cash dividend, distribution or right and may withhold the entire
purchase price or deduct from the purchase price the amount or value thereof, as
determined by Purchaser in its sole discretion.
 
    14. EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES, EXCHANGE LISTING AND
EXCHANGE ACT REGISTRATION. The purchase of Shares by Purchaser pursuant to the
Offer will reduce the number of Shares that might otherwise trade publicly and
will reduce the number of holders of Shares, which could adversely affect the
liquidity and market value of the remaining Shares held by the public.
 
    Depending upon the number of Shares purchased pursuant to the Offer, the
Shares may no longer meet the requirements of the NYSE for continued listing and
may be delisted from the NYSE. Parent intends to seek the delisting of the
Shares by the NYSE following consummation of the Offer.
 
    According to the NYSE's published guidelines, the NYSE would consider
delisting the Shares if, among other things, the number of record holders of at
least 100 Shares should fall below 1,200, the number of publicly held Shares
(exclusive of holdings of officers, directors and their families and other
concentrated holdings of 10% or more ("NYSE Excluded Holdings")) should fall
below 600,000 or the aggregate market value of publicly held Shares (exclusive
of NYSE Excluded Holdings) should fall below $5,000,000. The Company has advised
Purchaser that, as of May 5, 1997, there were 41,991,547 Shares outstanding,
held by approximately 1,800 holders of record. If, as a result of the purchase
of Shares pursuant to the Offer or otherwise, the Shares no longer meet the
requirements of the NYSE for continued listing and the listing of the Shares is
discontinued, the market for the Shares could be adversely affected.
 
    If the NYSE were to delist the Shares, it is possible that the Shares would
continue to trade on another securities exchange or in the over-the-counter
market and that price or other quotations would be reported by such exchange or
through the National Association of Securities Dealers Automated Quotation
System ("NASDAQ") or other sources. The extent of the public market therefor and
the availability of such quotations would depend, however, upon such factors as
the number of stockholders and/or the aggregate market value of such securities
remaining at such time, the interest in maintaining a market in the Shares on
the part of securities firms, the possible termination of registration under the
Exchange Act as described below, and other factors. Purchaser cannot predict
whether the reduction in the number of Shares that might otherwise trade
publicly would have an adverse or beneficial effect on the market price for or
marketability of the Shares or whether it would cause future market prices to be
greater or less than the Merger Consideration.
 
                                       32

    The Shares are currently "margin securities", as such term is defined under
the rules of the Board of Governors of the Federal Reserve System (the "Federal
Reserve Board"), which has the effect, among other things, of allowing brokers
to extend credit on the collateral of such securities. Depending upon factors
similar to those described above regarding listing and market quotations,
following the Offer it is possible that the Shares might no longer constitute
"margin securities" for purposes of the margin regulations of the Federal
Reserve Board, in which event such Shares could no longer be used as collateral
for loans made by brokers.
 
    The Shares are currently registered under the Exchange Act. Such
registration may be terminated upon application by the Company to the Commission
if the Shares are not listed on a national securities exchange and there are
fewer than 300 record holders. The termination of the registration of the Shares
under the Exchange Act would substantially reduce the information required to be
furnished by the Company to holders of Shares and to the Commission and would
make certain provisions of the Exchange Act, such as the short-swing profit
recovery provisions of Section 16(b), the requirement of furnishing a proxy
statement in connection with stockholders' meetings and the requirements of Rule
13e-3 under the Exchange Act with respect to "going private" transactions, no
longer applicable to the Shares. In addition, "affiliates" of the Company and
persons holding "restricted securities" of the Company may be deprived of the
ability to dispose of such securities pursuant to Rule 144 promulgated under the
Securities Act of 1933, as amended. If registration of the Shares under the
Exchange Act were terminated, the Shares would no longer be "margin securities"
or be eligible for NASDAQ reporting. Purchaser currently intends to seek to
cause the Company to terminate the registration of the Shares under the Exchange
Act as soon after consummation of the Offer as the requirements for termination
of registration are met.
 
    15. CERTAIN CONDITIONS OF THE OFFER. Notwithstanding any other provision of
the Offer, Purchaser will not be required to accept for payment or pay for any
Shares tendered pursuant to the Offer, and may terminate or amend the Offer

    of their subsidiaries to dispose of or to hold separate all or any material
    portion of the business or assets of the Company, Parent or any of their
    subsidiaries, as a result of the transactions contemplated by the Merger
    Agreement; (iii) seeking to impose or confirm limitations on the ability of

    approval and adoption of the Merger Agreement and the transactions
    contemplated thereby; (iv) seeking to require divestiture by Parent,
    Purchaser or any other affiliate of Parent of any Shares; or (v) which
    otherwise causes or gives rise to any circumstance, change in or effect on
    the Company, any Subsidiary or any circumstance, change in or effect on the
    Dialysis Business that is, or is reasonably likely to be, materially adverse
    to the value of the Dialysis Business or the Company and the Dialysis

    development that results from (i) the announcement of the transactions
    contemplated by the Merger Agreement or the Specialty Merger Transaction,
    (ii) general economic conditions, (iii) conditions that are generally
    applicable to the dialysis business, the renal care business or the

    or indirectly, in any of the consequences referred to in clauses (i) through
    (v) of paragraph (a) above;
 
        (c) there will have occurred any change, condition, event or development

        (d) there will have occurred (i) any general suspension of, or

    result of a specified decrease in a market index), (ii) a declaration of a
    banking moratorium or any suspension of payments in respect of banks in the
    United States or Sweden, (iii) any limitation (whether or not mandatory) by
    any government or governmental, administrative or regulatory authority or
    agency of the United States or Sweden on the extension of credit by banks or
    other lending institutions such that Parent is not reasonably able to obtain
    financing for the Offer on reasonable terms or (iv) a commencement of a war
    or material armed hostilities or other national or international calamity
    involving the United States or Sweden;
 
        (e) (i) it will have been publicly disclosed or Purchaser will have
    otherwise learned that beneficial ownership (determined for the purposes of
    this paragraph as set forth in Rule 13d-3 promulgated under the Exchange
    Act) of 20% or more of the then outstanding Shares has been acquired by any
    person, other than Parent or any of its affiliates or any other person not
    required to file a Schedule 13D under the rules promulgated under the
    Exchange Act or (ii) the Company's Board of Directors or any committee
    thereof will have (A) withdrawn or modified in a manner adverse to Parent or
    Purchaser the approval or recommendation of the Offer, the Merger or the
    Merger Agreement, or approved or recommended any acquisition proposal or any
    other acquisition of the Shares other than the Offer or the Merger or (B)
    resolved to do any of the foregoing;
 
        (f) (i) any representation or warranty which addresses matters as of a
    particular date shall not be true and correct as of such date, or (ii) any
    other representation or warranty shall not be true, as of the date of the
    Merger Agreement and as of the expiration of the Offer, unless the
    inaccuracies under all such representations and warranties together in their
    entirety, would not, individually or in the aggregate, have a Material
    Adverse Effect;
 
                                       34
<PAGE>
        (g) the Company will have failed to perform any obligation or to comply
    with any agreement or covenant of the Company to be performed or complied
    with by it under the Merger Agreement unless all such failures together in
    their entirety, would not, individually or in the aggregate, have a Material
    Adverse Effect;
 
        (h) the Merger Agreement will have been terminated in accordance with
    its terms; or
 
        (i) Purchaser and the Company will have agreed that Purchaser will

    Shares thereunder.
 
    The foregoing conditions are for the sole benefit of Purchaser and Parent
and may be asserted by Purchaser or Parent regardless of the circumstances
giving rise to any such condition or may be waived by Purchaser or Parent in
whole or in part at any time and from time to time in their sole discretion,
subject in each case to the terms of the Merger Agreement. The failure by Parent
or Purchaser at any time to exercise any of the foregoing rights will not be
deemed a waiver of any such right; the waiver of any such right with respect to
particular facts and other circumstances will not be deemed a waiver with
respect to any other facts and circumstances; and each such right will be deemed
an ongoing right that may be asserted at any time and from time to time.
 
    16. CERTAIN LEGAL MATTERS AND REGULATORY APPROVALS.
 
    GENERAL.  Based upon its examination of publicly available information with
respect to the Company and the review of certain information furnished by the
Company to Parent and discussions of representatives of Parent with
representatives of the Company during Parent's investigation of the Company,
except to the extent the Merger will require the Company to obtain new Medicare,
Medicaid or third party provider numbers, licenses or similar permits (see
"Section 11. Background of the Offer; Contacts with the Company; the Merger
Agreement and the Specialty Agreement"), neither Purchaser nor Parent is aware
of any license or other regulatory permit that appears to be material to the
business of the Company and the Subsidiaries, taken as a whole, which might be
adversely affected by the acquisition of Shares by Purchaser pursuant to the
Offer or, except as set forth below, of any approval or other action by any
domestic (federal or state) or foreign governmental, administrative or
regulatory authority or agency which would be required prior to the acquisition
of Shares by Purchaser pursuant to the Offer. Should any such approval or other
action be required, it is Purchaser's present intention to seek such approval or
action. Purchaser does not currently intend, however, to delay the purchase of
Shares tendered pursuant to the Offer pending the outcome of any such action or
the receipt of any such approval (subject to Purchaser's right to decline to
purchase Shares if any of the conditions in "Section 15. Certain Conditions of
the Offer" shall have occurred). There can be no assurance that any such
approval or other action, if needed, would be obtained without substantial
conditions or that adverse consequences might not result to the business of the
Company, Purchaser or Parent or that certain parts of the businesses of the
Company, Purchaser or Parent might not have to be disposed of or held separate
or other substantial conditions complied with in order to obtain such approval
or other action or in the event that such approval was not obtained or such
other action was not taken. Purchaser's obligation under the Offer to accept for
payment and pay for Shares is subject to certain conditions, including
conditions relating to the legal matters discussed in this "Section 16. Certain
Legal Matters and Regulatory Approvals". See "Section 15. Certain Conditions of
the Offer".
 
    STATE TAKEOVER LAWS.  The Company is incorporated under the laws of the
State of Delaware. In general, Section 203 of Delaware Law prevents an
"interested stockholder" (generally a person who owns or has the right to
acquire 15% or more of a corporation's outstanding voting stock, or an affiliate
or associate thereof) from engaging in a "business combination" (defined to
include mergers and certain other transactions) with a Delaware corporation for
a period of three years following the date such person became an interested
stockholder unless, among other things, prior to such date the board of
directors of the corporation approved either the business combination or the
transaction in which the interested stockholder became an interested
stockholder. On May 4, 1997, prior to the execution of the
 
                                       35
<PAGE>
Merger Agreement, the Board of Directors of the Company, by unanimous vote of
all directors present at a meeting held on such date, approved the Merger
Agreement, determined that each of the Offer and the Merger is fair to, and in
the best interest of, the stockholders of the Company. Accordingly, Section 203
is inapplicable to the Offer and the Merger.
 
    A number of other states have adopted laws and regulations applicable to
attempts to acquire securities of corporations which are incorporated, or have
substantial assets, stockholders, principal executive offices or principal
places of business, or whose business operations otherwise have substantial
economic effects, in such states. In EDGAR V. MITE CORP., the Supreme Court of
the United States invalidated on constitutional grounds the Illinois Business
Takeover Statute, which, as a matter of state securities law, made takeovers of
corporations meeting certain requirements more difficult. However, in 1987, in
CTS CORP. V. DYNAMICS CORP. OF AMERICA,the Supreme Court held that the State of
Indiana may, as a matter of corporate law and, in particular, with respect to
those aspects of corporate law concerning corporate governance, constitutionally
disqualify a potential acquiror from voting on the affairs of a target
corporation without the prior approval of the remaining stockholders. The state
law before the Supreme Court was by its terms applicable only to corporations
that had a substantial number of stockholders in the state and were incorporated
there.
 
    The Company, directly or through subsidiaries, conducts business in a number
of states throughout the United States, some of which have enacted takeover
laws. Purchaser does not know whether any of these laws will, by their terms,
apply to the Offer or the Merger and has not complied with any such laws. Should
any person seek to apply any state takeover law, Purchaser will take such action
as then appears desirable, which may include challenging the validity or
applicability of any such statute in appropriate court proceedings. In the event
it is asserted that one or more state takeover laws is applicable to the Offer
or the Merger, and an appropriate court does not determine that it is
inapplicable or invalid as applied to the Offer, Purchaser might be required to
file certain information with, or receive approvals from, the relevant state
authorities. In addition, if enjoined, Purchaser might be unable to accept for
payment any Shares tendered pursuant to the Offer, or be delayed in continuing
or consummating the Offer, and the Merger. In such case, Purchaser may not be
obligated to accept for payment any Shares tendered. See "Section 15. Certain
Conditions of the Offer".
 
    ANTITRUST.  Under the HSR Act and the rules that have been promulgated
thereunder by the FTC, certain acquisition transactions may not be consummated
unless certain information has been furnished to the Antitrust Division and the
FTC and certain waiting period requirements have been satisfied. The acquisition
of Shares by Purchaser pursuant to the Offer are subject to such requirements.
See "Section 2. Acceptance for Payment and Payment for Shares".
 
    Pursuant to the HSR Act, on May 9, 1997, Parent filed a Premerger
Notification and Report Form in connection with the purchase of Shares pursuant
to the Offer with the Antitrust Division and the FTC. Under the provisions of
the HSR Act applicable to the Offer, the purchase of Shares pursuant to the
Offer may not be consummated until the expiration of a 15-calendar day waiting
period following the filing by Parent. Accordingly, the waiting period under the
HSR Act applicable to the purchase of Shares pursuant to the Offer will expire
at 11:59 p.m., New York City time, on May 23, 1997, unless such waiting period
is earlier terminated by the FTC and the Antitrust Division or extended by a
request from the FTC or the Antitrust Division for additional information or
documentary material prior to the expiration of the waiting period. Pursuant to
the HSR Act, Parent has requested early termination of the waiting period
applicable to the Offer. There can be no assurance, however, that the 15-day HSR
Act waiting period will be terminated early. If either the FTC or the Antitrust
Division were to request additional information or documentary material from
Parent with respect to the Offer, the waiting period with respect to the Offer
would expire at 11:59 p.m., New York City time, on the tenth calendar day after
the date of substantial compliance by Parent with such request. Thereafter, the
waiting period could be extended only by court order. If the acquisition of
Shares is delayed pursuant to a request by the FTC or the Antitrust Division for
additional information or documentary material pursuant to the HSR Act, the
Offer may, but need not, be
 
                                       36
<PAGE>
extended and, in any event, the purchase of and payment for Shares will be
deferred until 10 days after the request is substantially complied with, unless
the extended period expires on or before the date when the initial 15-day period
would otherwise have expired, or unless the waiting period is sooner terminated
by the FTC and the Antitrust Division. Only one extension of such waiting period
pursuant to a request for additional information is authorized by the HSR Act
and the rules promulgated thereunder, except by court order. Any such extension
of the waiting period will not give rise to any withdrawal rights not otherwise
provided for by applicable law. See "Section 4. Withdrawal Rights". It is a
condition to the Offer that the waiting period applicable under the HSR Act to
the Offer expire or be terminated. See "Section 2. Acceptance for Payment and
Payment for Shares" and "Section 15. Certain Conditions of the Offer".
 
    The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as the proposed acquisition of Shares by
Purchaser pursuant to the Offer. At any time before or after the purchase of
Shares pursuant to the Offer by Purchaser, the FTC or the Antitrust Division
could take such action under the antitrust laws as it deems necessary or
desirable in the public interest, including seeking to enjoin the purchase of
Shares pursuant to the Offer or seeking the divestiture of Shares purchased by
Purchaser or the divestiture of substantial assets of Parent, the Company or
their respective subsidiaries. Private parties and state attorneys general may
also bring legal action under federal or state antitrust laws under certain
circumstances. Based upon an examination of information available to Parent
relating to the businesses in which Parent, the Company and their respective
subsidiaries are engaged, Parent and Purchaser believe that the Offer will not
violate the antitrust laws. Nevertheless, there can be no assurance that a
challenge to the Offer on antitrust grounds will not be made or, if such a
challenge is made, what the result would be. See "Section 15. Certain Conditions
of the Offer", for certain conditions to the Offer, including conditions with
respect to litigation.
 
    17. FEES AND EXPENSES. Except as set forth below, Purchaser will not pay any
fees or commissions to any broker, dealer or other person for soliciting tenders
of Shares pursuant to the Offer.
 
    UBS is acting as Dealer Manager in connection with the Offer and has
provided certain financial advisory services in connection with the acquisition
of the Company. Gambro has agreed to pay UBS a retainer fee of $150,000 and a
transaction fee (against which the foregoing retainer fee will be credited) of
$5,000,000, of which $1,500,000 will become payable upon commencement of the
Offer and the remainder of which will become payable at the closing of the
Merger. Gambro has also agreed to reimburse UBS for all reasonable out-of-pocket
expenses incurred by UBS, including the reasonable fees and expenses of legal
counsel, and to indemnify UBS against certain liabilities and expenses in
connection with its engagement, including certain liabilities under the federal
securities laws.
 
    Purchaser and Parent have retained Georgeson & Company Inc., as the
Information Agent, and The Bank of New York, as the Depositary, in connection
with the Offer. The Information Agent may contact holders of Shares by mail,
telephone, telex, telecopy, telegraph and personal interview and may request
banks, brokers, dealers and other nominee stockholders to forward materials
relating to the Offer to beneficial owners.
 
    As compensation for acting as Information Agent in connection with the
Offer, Georgeson & Company Inc. will be paid a fee of $12,500 and will also be
reimbursed for certain out-of-pocket expenses and may be indemnified against
certain liabilities and expenses in connection with the Offer, including certain
liabilities under the federal securities laws. Purchaser will pay the Depositary
reasonable and customary compensation for its services in connection with the
Offer, plus reimbursement for out-of-pocket expenses, and will indemnify the
Depositary against certain liabilities and expenses in connection therewith,
including under federal securities laws. Brokers, dealers, commercial banks and
trust companies will be reimbursed by Purchaser for customary handling and
mailing expenses incurred by them in forwarding material to their customers.

    18. MISCELLANEOUS. Purchaser is not aware of any jurisdiction where the
making of the Offer is prohibited by any administrative or judicial action
pursuant to any valid state statute. If Purchaser becomes aware of any valid
state statute prohibiting the making of the Offer or the acceptance of Shares
pursuant thereto, Purchaser will make a good faith effort to comply with any
such state statute. If, after such good faith effort, Purchaser cannot comply
with any such state statute, the Offer will not be made to (nor will tenders be
accepted from or on behalf of) the holders of Shares in such state. In any
jurisdiction where the securities, blue sky or other laws require the Offer to
be made by a licensed broker or dealer, the Offer shall be deemed to be made on
behalf of Purchaser by the Dealer Manager or by one or more registered brokers
or dealers licensed under the laws of such jurisdiction.
 
    NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY
REPRESENTATION ON BEHALF OF PURCHASER OR THE COMPANY NOT CONTAINED IN THIS OFFER
TO PURCHASE OR IN THE LETTER OF TRANSMITTAL, AND IF GIVEN OR MADE, SUCH
INFORMATION OR REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED.
 
    Pursuant to Rule 14d-3 of the General Rules and Regulations under the
Exchange Act, Parent and Purchaser have filed with the Commission the Schedule
14D-1, together with exhibits, furnishing certain additional information with
respect to the Offer. The Schedule 14D-1 and any amendments thereto, including
exhibits, may be inspected at, and copies may be obtained from, the same places
and in the same manner as set forth in "Section 7. Certain Information
Concerning the Company" (except that they will not be available at the regional
offices of the Commission).

Ladies and Gentlemen:
 
    The undersigned hereby tenders to Gambro Healthcare Acquisition Corp., a
Delaware corporation ("Purchaser") and an indirect wholly owned subsidiary of
Incentive AB, a corporation organized under the laws of Sweden, the
above-described shares of Common Stock, par value $.01 per share, of Vivra
Incorporated, a Delaware corporation (the "Company") (all shares of such Common
Stock from time to time outstanding being, collectively, the "Shares"), pursuant
to Purchaser's offer to purchase all Shares, at $35.62 per Share, net to the
seller in cash, upon the terms and subject to the conditions set forth in the
Offer to Purchase, dated May 9, 1997 (the "Offer to Purchase"), receipt of which
is hereby acknowledged, and in this Letter of Transmittal (which, together with
the Offer to Purchase, constitute the "Offer"). The undersigned understands that
Purchaser reserves the right to transfer or assign, in whole or from time to
time in part, to one or more of its affiliates, the right to purchase all or any
portion of the Shares tendered pursuant to the Offer.
 
    Subject to, and effective upon, acceptance for payment of the Shares
tendered herewith, in accordance with the terms of the Offer, the undersigned
hereby sells, assigns and transfers to, or upon the order of, Purchaser all
right, title and interest in and to all the Shares that are being tendered
hereby and all dividends, distributions (including, without limitation,
distributions of additional Shares) and rights declared, paid or distributed in
respect of such Shares on or after May 5, 1997 (collectively, "Distributions")
and irrevocably appoints the Depositary the true and lawful agent and
attorney-in-fact of the undersigned with respect to such Shares and all
Distributions, with full power of substitution (such power of attorney being
deemed to be an irrevocable power coupled with an interest), to (i) deliver
Share Certificates evidencing such Shares and all Distributions, or transfer
ownership of such Shares and all Distributions on the account books maintained
by a Book-Entry Transfer Facility, together, in either case, with all
accompanying evidences of transfer and authenticity, to or upon the order of
Purchaser, (ii) present such Shares and all Distributions for transfer on the
books of the Company and (iii) receive all benefits and otherwise exercise all
rights of beneficial ownership of such Shares and all Distributions, all in
accordance with the terms of the Offer.
 
    The undersigned hereby irrevocably appoints Mats L. Wahlstrom and Ralph Z.
Levy, Jr., and each of them, as the attorneys and proxies of the undersigned,
each with full power of substitution, to vote in such manner as each such
attorney and proxy or his substitute shall, in his sole discretion, deem proper
and otherwise act (by written consent or otherwise) with respect to all the
Shares tendered hereby which have been accepted for payment by Purchaser prior
to the time of such vote or other action and all Shares and other securities
issued in Distributions in respect of such Shares, which the undersigned is
entitled to vote at any meeting of stockholders of the Company (whether annual
or special and whether or not an adjourned or postponed meeting) or consent in
lieu of any such meeting or otherwise. This proxy and power of attorney is
coupled with an interest in the Shares tendered hereby, is irrevocable and is
granted in consideration of, and is effective upon, the acceptance for payment
of such Shares by Purchaser in
<PAGE>
accordance with other terms of the Offer. Such acceptance for payment shall
revoke all other proxies and powers of attorney granted by the undersigned at
any time with respect to such Shares (and all Shares and other securities issued
in Distributions in respect of such Shares), and no subsequent proxy or power of
attorney shall be given or written consent executed (and if given or executed,
shall not be effective) by the undersigned with respect thereto. The undersigned
understands that, in order for Shares to be deemed validly tendered, immediately
upon Purchaser's acceptance of such Shares for payment, Purchaser must be able
to exercise full voting and other rights with respect to such Shares, including,
without limitation, voting at any meeting of the Company's stockholders then
scheduled.
 
    The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Shares tendered
hereby and all Distributions, that when such Shares are accepted for payment by
Purchaser, Purchaser will acquire good, marketable and unencumbered title
thereto and to all Distributions, free and clear of all liens, restriction,
charges and encumbrances, and that none of such Shares and Distributions will be
subject to any adverse claim. The undersigned, upon request, shall execute and
deliver all additional documents deemed by the Depositary or Purchaser to be
necessary or desirable to complete the sale, assignment and transfer of the
Shares tendered hereby and all Distributions. In addition, the undersigned shall
remit and transfer promptly to the Depositary for the account of Purchaser all
Distributions in respect of the Shares tendered hereby, accompanied by
appropriate documentation of transfer, and pending such remittance and transfer
or appropriate assurance thereof, Purchaser shall be entitled to all rights and
privileges as owner of each such Distribution and may withhold the entire
purchase price of the Shares tendered hereby, or deduct from such purchase
price, the amount or value of such Distribution as determined by Purchaser in
its sole discretion.
 
    No authority herein conferred or agreed to be conferred shall be affected
by, and all such authority shall survive, the death or incapacity of the
undersigned. All obligations of the undersigned hereunder shall be binding upon
the heirs, personal representatives, successors and assigns of the undersigned.
Except as stated in the Offer to Purchase, this tender is irrevocable.
 
    The undersigned understands that tenders of Shares pursuant to any one of
the procedures described in "Section 3. Procedures for Accepting the Offer and
Tendering Shares" of the Offer to Purchase and in the instructions hereto will
constitute the undersigned's acceptance of the terms and conditions of the
Offer. Purchaser's acceptance of such Shares for payment will constitute a
binding agreement between the undersigned and Purchaser upon the terms and
subject to the conditions of the Offer.
 
    Unless otherwise indicated herein in the box entitled "Special Payment
Instructions", please issue the check for the purchase price of all Shares
purchased, and return all Share Certificates evidencing Shares not purchased or
not tendered in the name(s) of the registered holder(s) appearing above under

box entitled "Special Delivery Instructions", please mail the check for the
purchase price of all Shares purchased and all Share Certificates evidencing
Shares not tendered or not purchased (and accompanying documents, as
appropriate) to the address(es) of the registered holder(s) appearing above

"Special Payment Instructions" and "Special Delivery Instructions" are both

and return all Share Certificates evidencing Shares not purchased or not
tendered in the name(s) of, and mail such check and Share Certificates to, the

"Special Payment Instructions", please credit any Shares tendered hereby and
delivered by book-entry transfer, but which are not purchased by crediting the
account at the Book-Entry Transfer Facility designated above. The undersigned
recognizes that Purchaser has no obligation, pursuant to the Special Payment
Instructions, to

transfer any Shares from the name of the registered holder(s) thereof if
Purchaser does not purchase any of the Shares tendered hereby.

must be guaranteed by a firm which is a member of the Medallion Signature
Guarantee Program, or by any other "eligible guarantor institution", as such
term is defined in Rule 17Ad-5 promulgated under the Securities Exchange Act of
1934, as amended (each of the foregoing being referred to as an "Eligible
Institution"), unless (i) this Letter of Transmittal is signed by the registered
holder(s) of the Shares (which term, for purposes of this document, shall
include any participant in a Book-Entry Transfer Facility whose name appears on

holder(s) has (have) completed neither the box entitled "Special Payment

    2. DELIVERY OF LETTER OF TRANSMITTAL AND SHARE CERTIFICATES. This Letter of
Transmittal is to be used either if Share Certificates are to be forwarded

of Transmittal (or facsimile thereof) and any other documents required by this
Letter of Transmittal, must be received by the Depositary at one of its
addresses set forth on the reverse hereof prior to the Expiration Date (as
defined in "Section 1. Terms of the Offer; Expiration Date" of the Offer to
Purchase). If Share Certificates are forwarded to the Depositary in multiple
deliveries, a properly completed and duly executed Letter of Transmittal must
accompany each such delivery. Stockholders whose Share Certificates are not
immediately available, who cannot deliver their Share Certificates and all other
required documents to the Depositary prior to the Expiration Date or who cannot
complete the procedure for delivery by book-entry transfer on a timely basis may
tender their Shares pursuant to the guaranteed delivery procedure described in
"Section 3. Procedures for Accepting the Offer and Tendering Shares" of the
Offer to Purchase. Pursuant to such procedure: (i) such tender must be made by

into the Depositary's account at a Book-Entry Transfer Facility of all Shares
delivered by book-entry transfer, in each case together with a Letter of
Transmittal (or a facsimile thereof), properly completed and duly executed, with
any required signature guarantees (or, in the case of a book-entry transfer, an
Agent's Message (as defined in "Section 3. Procedures for Accepting the Offer
and Tendering Shares" of the Offer to Purchase)), and any other documents
required by this Letter of Transmittal, must be received by the Depositary
within three New York Stock Exchange ("NYSE") trading days after the date of
execution of such Notice of Guaranteed Delivery, all as described in "Section 3.
Procedures for Accepting the Offer and Tendering Shares" of the Offer to
Purchase.
 
    THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, SHARE CERTIFICATES AND
ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH ANY BOOK-ENTRY TRANSFER
FACILITY, IS AT THE OPTION AND RISK OF THE TENDERING STOCKHOLDER, AND THE
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF
DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY
INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO
ENSURE TIMELY DELIVERY.
 
    No alternative, conditional or contingent tenders will be accepted and no
fractional Shares will be purchased. By execution of this Letter of Transmittal
(or a facsimile hereof), all tendering stockholders waive any right to receive
any notice of the acceptance of their Shares for payment.
 
    3. INADEQUATE SPACE. If the space provided herein under "Description of
Shares Tendered" is inadequate, the Share Certificate numbers, the number of
Shares evidenced by such Share Certificates and the number of Shares tendered
should be listed on a separate schedule and attached hereto.
 
    4. PARTIAL TENDERS (NOT APPLICABLE TO STOCKHOLDERS WHO TENDER BY BOOK-ENTRY
TRANSFER). If fewer than all the Shares evidenced by any Share Certificate
delivered to the Depositary herewith are to be tendered hereby, fill in the
number of Shares which are to be tendered in the box entitled "Number of Shares
Tendered". In such cases, new Share Certificate(s) evidencing the remainder of
the Shares that were evidenced by the Share Certificates delivered to the
Depositary herewith will be sent to the person(s) signing this Letter of
Transmittal, unless otherwise provided
<PAGE>
in the box entitled "Special Delivery Instructions" on the reverse hereof, as
soon as practicable after the expiration or termination of the Offer. All Shares
evidenced by Share Certificates delivered to the Depositary will be deemed to
have been tendered unless otherwise indicated.
 
    5. SIGNATURES ON LETTER OF TRANSMITTAL; STOCK POWERS AND ENDORSEMENTS. If
this Letter of Transmittal is signed by the registered holder(s) of the Shares
tendered hereby, the signature(s) must correspond with the name(s) as written on
the face of the Share Certificates evidencing such Shares without alteration,
enlargement or any other change whatsoever.
 
    If any Share tendered hereby is owned of record by two or more persons, all
such persons must sign this Letter of Transmittal.
 
    If any of the Shares tendered hereby are registered in the names of
different holders, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal as there are different registrations of such
Shares.
 
    If this Letter of Transmittal is signed by the registered holder(s) of the
Shares tendered hereby, no endorsements of Share Certificates or separate stock
powers are required, unless payment is to be made to, or Share Certificates
evidencing Shares not tendered or not purchased are to be issued in the name of,
a person other than the registered holder(s), in which case, the Share
Certificate(s) evidencing the Shares tendered hereby must be endorsed or
accompanied by appropriate stock powers, in either case signed exactly as the
name(s) of the registered holder(s) appear(s) on such Share Certificate(s).
Signatures on such Share Certificate(s) and stock powers must be guaranteed by
an Eligible Institution.
 
    If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Shares tendered hereby, the Share Certificate(s)
evidencing the Shares tendered hereby must be endorsed or accompanied by
appropriate stock powers, in either case signed exactly as the name(s) of the
registered holder(s) appear(s) on such Share Certificate(s). Signatures on such
Share Certificate(s) and stock powers must be guaranteed by an Eligible
Institution.
 
    If this Letter of Transmittal or any Share Certificate or stock power is
signed by a trustee, executor, administrator, guardian, attorney-in-fact,
officer of a corporation or other person acting in a fiduciary or representative
capacity, such person should so indicate when signing, and proper evidence
satisfactory to Purchaser of such person's authority so to act must be
submitted.
 
    6. STOCK TRANSFER TAXES. Except as otherwise provided in this Instruction 6,
Purchaser will pay all stock transfer taxes with respect to the sale and
transfer of any Shares to it or its order pursuant to the Offer. If, however,
payment of the purchase price of any Shares purchased is to be made to, or Share
Certificate(s) evidencing Shares not tendered or not purchased are to be issued
in the name of, a person other than the registered holder(s), the amount of any
stock transfer taxes (whether imposed on the registered holder(s), such other
person or otherwise) payable on account of the transfer to such other person
will be deducted from the purchase price of such Shares purchased, unless
evidence satisfactory to Purchaser of the payment of such taxes, or exemption
therefrom, is submitted. Except as provided in this Instruction 6, it will not
be necessary for transfer tax stamps to be affixed to the Share Certificates
evidencing the Shares tendered hereby.
 
    7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If a check for the purchase
price of any Shares tendered hereby is to be issued, or Share Certificate(s)
evidencing Shares not tendered or not purchased are to be issued, in the name of
a person other than the person(s) signing this Letter of Transmittal or if such
check or any such Share Certificate is to be sent to someone other than the
person(s) signing this Letter of Transmittal or to the person(s) signing this
Letter of Transmittal but at an address other than that shown in the box
entitled "Description of Shares Tendered" on the reverse hereof, the appropriate
boxes on the reverse of this Letter of Transmittal must be completed.
Stockholders delivering Shares tendered hereby by book-entry transfer may
request that Shares not purchased be credited to such account maintained at a
Book-Entry Transfer Facility as such stockholder may designate in the box
entitled "Special Payment Instructions" on the reverse hereof. If no such
instructions are given, all such Shares not purchased will be returned by
crediting the account at the Book-Entry Transfer Facility designated on the

    9. SUBSTITUTE FORM W-9. Each tendering stockholder is required to provide
the Depositary with a correct Taxpayer Identification Number ("TIN") on the
Substitute Form W-9 which is provided under "Important Tax Information" below,
and to certify, under penalties of perjury, that such number is correct and that
such stockholder is not subject to backup withholding of federal income tax. If
a tendering stockholder has been notified by the Internal Revenue Service that
such stockholder is subject to backup withholding, such stockholder must cross
out item (2) of the Certification box of the Substitute Form W-9, unless such
stockholder has since been notified by the Internal Revenue Service that such
stockholder is no longer subject to backup withholding. Failure to provide the
information on the Substitute Form W-9 may subject the tendering stockholder to
31% federal income tax withholding on the payment of the purchase price of all
Shares purchased from such stockholder. If the tendering stockholder has not
been issued a TIN and has applied for one or intends to apply for one in the
near future, such stockholder should write "Applied For" in the space provided
for the TIN in Part I of the Substitute Form W-9, and sign and date the
Substitute Form W-9. If "Applied For" is written in Part I and the Depositary is
not provided with a TIN within 60 days, the Depositary will withhold 31% on all
payments of the purchase price to such stockholder until a TIN is provided to
the Depositary.
 
    IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE HEREOF), PROPERLY

                           IMPORTANT TAX INFORMATION
 
    Under the federal income tax law, a stockholder whose tendered Shares are
accepted for payment is required by law to provide the Depositary (as payer)
with such stockholder's correct TIN on Substitute Form W-9 below. If such
stockholder is an individual, the TIN is such stockholder's social security
number. If the Depositary is not provided with the correct TIN, the stockholder
may be subject to a $50 penalty imposed by the Internal Revenue Service and
payments that are made to such stockholder with respect to Shares purchased
pursuant to the Offer may be subject to backup withholding of 31%. In addition,
if a stockholder makes a false statement that results in no imposition of backup
withholding, and there was no reasonable basis for such statement, a $500
penalty may also be imposed by the Internal Revenue Service.
 
    Certain stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, such individual must submit a statement, signed under penalties of
perjury, attesting to such individual's exempt status. Forms of such statements
can be obtained from the Depositary. See the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional instructions. A stockholder should consult his or her tax advisor as
to such stockholder's qualification for exemption from backup withholding and
the procedure for obtaining such exemption.
 
    If backup withholding applies, the Depositary is required to withhold 31% of
any payments made to the stockholder. Backup withholding is not an additional
tax. Rather, the tax liability of persons subject to backup withholding will be
reduced by the amount of tax withheld. If withholding results in an overpayment
of taxes, a refund may be obtained from the Internal Revenue Service.
 
PURPOSE OF SUBSTITUTE FORM W-9
 
    To prevent backup withholding on payments that are made to a stockholder
with respect to Shares purchased pursuant to the Offer, the stockholder is
required to notify the Depositary of such stockholder's correct TIN by
completing the form below certifying (a) that the TIN provided on Substitute
Form W-9 is correct (or that such stockholder is awaiting a TIN) and (b) that
(i) such stockholder has not been notified by the Internal Revenue Service that
such stockholder is subject to backup withholding as a result of a failure to
report all interest or dividends or (ii) the Internal Revenue Service has
notified such stockholder that such stockholder is no longer subject to backup
withholding.
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
    The stockholder is required to give the Depositary the social security
number or employer identification number of the record holder of the Shares
tendered hereby. If the Shares are in more than one name or are not in the name
of the actual owner, consult the enclosed Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9 for additional guidance on
which number to report. If the tendering stockholder has not been issued a TIN
and has applied for a number or intends to apply for a number in the near
future, the stockholder should write "Applied For" in the space provided for the
TIN in Part I, and sign and date the Substitute Form W-9. If "Applied For" is
written in Part I and the Depositary is not provided with a TIN within 60 days,
the Depositary will withhold 31% of all payments of the purchase price to such
stockholder until a TIN is provided to the Depositary.

affirmations may subject you to criminal penalties including fines and/or
imprisonment.

defined below) is not aware of any state where the making of the Offer is
prohibited by administrative or judicial action pursuant to any valid state
statute. If Purchaser becomes aware of any valid state statute prohibiting the
making of the Offer or the acceptance of Shares pursuant thereto, Purchaser will
make a good faith effort to comply with such state statute. If, after such good
faith effort, Purchaser cannot comply with such state statute, the Offer will
not be made to (nor will tenders be accepted from or on behalf of) the holders
of Shares in such state. In any jurisdiction where the securities, blue sky or

                               Vivra Incorporated

                     an indirect wholly owned subsidiary of

                                  Incentive AB

      Gambro Healthcare Acquisition Corp., a Delaware corporation ("Purchaser")
and an indirect wholly owned subsidiary of Incentive AB, a corporation organized
under the laws of Sweden ("Parent"), is offering to purchase all outstanding
shares of Common Stock, par value $.O1 per share (the "Shares"), of Vivra
Incorporated, a Delaware corporation (the "Company"), at a price of $35.62 per
Share, net to the seller in cash, upon the terms and subject to the conditions
set forth in the Offer to Purchase, dated May 9, 1997 (the "Offer to Purchase"),
and in the related Letter of Transmittal (which together constitute the
"Offer"). Following the Offer, Purchaser intends to effect the Merger described
below.

   -----------------------------------------------------------------------------
      THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK
      CITY TIME, ON FRIDAY, JUNE 6,1997, UNLESS THE OFFER IS EXTENDED.
   -----------------------------------------------------------------------------

      The Offer is conditioned upon, among other things, (i) there being validly
tendered and not withdrawn prior to the expiration of the Offer at least a
majority of the Shares outstanding on a fully diluted basis, (ii) the expiration
or termination of any applicable waiting period under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, and (iii) the consummation of the Specialty
Merger Transaction (as described in the Offer to Purchase) and the receipt by
the Company of cash proceeds therefor, after providing for all applicable income
taxes (using an assumed income tax rate of 41%), of not less than $76,900,000.
The Offer is also subject to other terms and conditions contained in the Offer
to Purchase.

      The Offer is being made pursuant to an Agreement and Plan of Merger dated
as of May 5, 1997 (the "Merger Agreement") among Parent, Purchaser and the
Company. The Merger Agreement provides that, among other things, as soon as
practicable after the purchase of Shares pursuant to the Offer and the
satisfaction of the other conditions set forth in the Merger Agreement,
Purchaser will be merged with and into the Company (the "Merger"). Following
consummation of the Merger, the Company will continue as the surviving
corporation (the "Surviving Corporation") and will become a wholly owned
subsidiary of Parent. At the effective time of the Merger (the "Effective
Time"), each Share issued and outstanding immediately prior to the Effective
Time (other than Shares held in the treasury of the Company, or owned by
Purchaser, Parent or any direct or indirect wholly owned subsidiary of Parent or
of the Company immediately prior to the Effective Time, and other than Shares
held by stockholders who shall have demanded and perfected appraisal rights)
will be cancelled and converted automatically into the right to receive $35.62
in cash, or any higher price that may be paid per Share in the Offer, without
interest.

      The Board of Directors of the Company unanimously has determined that each
of the Offer and the Merger is fair to, and in the best interests of, the
stockholders of the Company, and recommends that stockholders accept the Offer
and tender their Shares pursuant to the Offer.

      For purposes of the Offer, Purchaser will be deemed to have accepted for
payment (and thereby purchased) Shares validly tendered and not properly
withdrawn as, if and when Purchaser gives oral or written notice to The Bank of
New York (the "Depositary") of Purchaser's acceptance for payment of such Shares
pursuant to the Offer. Upon the terms and subject to the conditions of the
Offer, payment for Shares accepted for payment pursuant to the Offer will be
made by deposit of the purchase price therefor with the Depositary, which will
act as agent for tendering stockholders for the purpose of receiving payments
from Purchaser and transmitting such payments to tendering stockholders whose
Shares have been accepted for payment. Under no circumstances will interest on
the purchase price for Shares be paid, regardless of any extension of the Offer
or delay in making such payment. In all cases, payment for Shares tendered and
accented for payment pursuant to the Offer will be made only after timely
receipt by the Depositary of (1) the certificates evidencing such Shares (the
"Share Certificates") or timely confirmation of a book-entry transfer of such
Shares into the Depositary's account at one of the Book-Entry Transfer
Facilities (as defined in "Section 2. Acceptance for Payment and Payment for

followed as promptly as practicable by public announcement thereof, such
announcement to be made no later than 9:00 a.m., New York City time, on the next

Procedures for Accepting the Offer and Tendering Shares" of the Offer to

      Incentive's Gambro Group to acquire Vivra Incorporated

Stockholm (May 5, 1997). Incentive AB and Vivra Incorporated ("Vivra") announced
today that both companies have signed a definitive merger agreement under which
Incentive will acquire Vivra's Renal Care business ("VRC"), including its
nephrology disease management and nephrology physician practice management
operation. Incentive intends to merge VRC with the Gambro Group, its wholly
owned, worldwide, fully integrated dialysis and medical technology business.

      Pursuant to the merger agreement, a cash tender offer will be commenced by
a wholly owned subsidiary of Incentive no later than May 9, 1997, to acquire all
of the outstanding shares of Vivra common stock for $35.62 per share or a total
cash consideration of $1,592 million, of which $33.90 represents Incentive's net
consideration for VRC, or a total cash consideration of $1,515 million. As part
of the transaction, Vivra has also signed a definitive agreement to sell Vivra
Specially Partners ("VSP"), its physician network and disease management
division, to a new company formed by Texas Pacific Group, Hellman & Freedman
Capital Partners III, LP. and Bain Capital for $85 million, representing net
after-tax proceeds of $77 million or approximately $1.72 per Vivra share. The
VSP sale agreement is subject to the expiration or termination of the waiting
periods under the Hart- Scott-Rodino Act and will close immediately prior to the
consummation of the Incentive tender offer.

      The $35.62 per share cash price represents a premium of 38.1% over the
average closing price of Vivra shares of $25.80 over the last 20 business days.

      The Board of Directors of Vivra has reviewed the merger agreement on
behalf of its stockholders and has recommended that such stockholders tender
their shares pursuant to the offer.

      The tender offer shall be conditional upon the valid tender of Vivra
shares representing a majority of the voting power of Vivra, the expiration or
termination of the waiting periods under applicable antitrust and competition
laws, the receipt of proceeds from the sale of VSP, and certain other matters.
The tender offer is expected to be completed in early June. All shares not
purchased in the tender offer will be converted into the right to receive $35.62
per share in a second step merger following the tender offer.

      The combination of VRC with Gambro will create a company with pro form
1996 worldwide revenues of $2.0 billion and earnings before interest, taxes,
depreciation and amortization ("EBITDA") of $410 million. The transaction is
expected to generate significant operating synergies. Together the companies
will serve approximately 26,000 dialysis patients in the United States.

                                        2


      Mikael Lilius, President and Chief Executive Officer of Incentive said:
"This transaction represents a major strategic move for Incentive and continues
our strong thrust into the high growth health care sector. We have consistently
restructured and shifted our resources into this highly attractive area. The
acquisition of Vivra Renal Care is a logical next step in the development of
Incentive Group and demonstrates our strong commitment to shareholder value
creation".

      Berthold Lindqvist, President and Chief Executive Officer of Gambro said:
"Vivra Renal Care is a well-managed company that fits well with Gambro. VRC will
strengthen our position as a global leader in renal care. We pioneered the
forward integration strategy in the United States and have distinguished
ourselves as high-quality care providers. With this merger, we will strengthen
Gambro's position as a leading, fully integrated, renal care management company
with multiregional presence; furthermore this transaction will generate
significant operating synergles, while allowing Gambro to continue to provide a
service of the highest quality".

      As a result of the change in control, resulting from Incentive's purchase
of Vivra shares pursuant to the tender offer, Vivra will thereafter be required
to offer to purchase the 5% Convertible Subordinated Notes Due 2001 from each of
the holders for the principal amount thereof plus accrued and unpaid interest.

      The impact of the acquisition is expected to be dilutive to Incentive's
earnings during both 1997 and 1998 due primarily to the goodwill charges
attributable to the transaction. The new goodwill will be amortized over twenty
years in accordance with Swedish GAAP. On a pro forma 1996 basis, the total
negative effect would have been SEK 7-8 per share. However, Incentive expects
the acquisition to enhance cash earnings growth (calculated before charges for
depreciation and goodwill amortisation), with an accretive impact in its first
full year and significant contributions thereafter.

      Pro forma solidity (equity including minority interests divided by total
assets) of Incentive as at 31 December, 1996, will decrease from 42% to 31%.
Adjusted for market value in associated companies, the solidity will decrease
from 60% to 48%. Total assets will increase by approximately SEK 12 billion from
SEK 35 billion to SEK 47 billion. Incentive will continue to focus the group
healthcare and reduce the level of debt.

      Vivra is the second largest provider of dialysis services in the United
States with approximately 15,800 patients at 262 centers in 28 states and the
District of Columbia. In fiscal 1996, Vivra had total revenues of $517 million
and EBITDA of approximately $105 million. During the same period, VRC
contributed operating revenues of $411 million and EBITDA in excess of $100
million. VSP provides physician network and disease management services to
managed care and provider organizations in the United States with approximately
1,500 affiliated network physicians.

shall use reasonable efforts to minimise the taxation and other costs for the

undrawn amount of the Total Commitments (but, if in part, in an integral
multiple of an Original Dollar Amount of $5,000,000). Any cancellation in part
shall be applied against the Commitment of each Bank pro rata.

            8.1   Selection

            (a) The Borrower may select an Interest Period for a Loan in either
the relevant Request or, if the Loan has been borrowed, a notice received by the
Agent not later than 10.00 a.m. on the third (in the case of a Loan to be

Business Day before the commencement of that Interest Period. 
<PAGE>
                                       15


Each Interest Period for a Loan will commence on its Drawdown Date or the expiry
of its preceding Interest Period.

            (b) Subject to the following provisions of this Clause 8 (Interest
Periods), each Interest Period will be either an approved duration or an
optional duration as so selected under paragraph (a) above.

            In this Clause 8 (Interest Periods):

            "approved duration" means one, three or six months; and

            "optional duration" means any period other than one, three or six
      months agreed by the Banks.

            (c) If the Borrower fails to select an Interest Period for an
outstanding Loan in accordance with paragraph (a) above, that Interest Period
will, subject to the other provisions of this Clause 8 (Interest Periods), be
three months.

            (d) No more than six Interest Periods of one month's duration may be
selected in any calendar year.

            8.2   Selection of an optional duration

            (a) If the Borrower selects an Interest Period of an optional
duration, it may also select an Interest Period of an approved duration to apply
if the selection of an optional duration becomes ineffective in accordance with
paragraph (b) below.

            (b)   If:-

            (i) the Borrower requests an Interest Period of an optional
      duration; and

            (ii) the Agent receives notice from a Bank not later than 3:00 p.m.
      three Business Days prior to the commencement of the Interest Period that
      matching deposits are not available to it in the ordinary course of
      business in the relevant interbank market to fund its participation in the
      Loan for that Interest Period,

the Interest Period for that Loan shall be the alternative period so specified
or, in the absence of any alternative selection and subject to the following
provisions of this Clause 8, three months. In this event, the Agent shall
promptly notify the Borrower and the Banks of the new Interest Period for the
Loan.

            8.3   Non-Business Days

            If an Interest Period would otherwise end on a day which is not a

not).

                                       16


            8.4   Consolidation and splitting

            (a) The number of Interest Periods current hereunder at any time
with different expiry dates shall not exceed 10.

            (b) If the number of Interest Periods current hereunder with
different expiry dates reaches 10, the first Interest Period for any additional
Loan must end on the same day as an existing Interest Period for another Loan
for the same Borrower and both such Loan shall thereafter (if in the same
currency and subject to paragraph (c) below) be consolidated.

            (c) Subject to paragraph (a) above, the Borrower may, in any Request
or any notice given pursuant to Clause 8.1(a) above, split any Loan (including
any consolidated Loan) into two or more Loans (provided that the Original Dollar
Amount of each resulting Loan is a minimum of $5,000,000).

            8.5   No overrunning

            If an Interest Period in respect of a Loan would otherwise overrun
the Final Repayment Date, it shall be shortened so that it ends on the Final
Repayment Date.

            8.6   Other adjustments

            The Agent and the Borrowers' Agent may, with the consent of the

            9.1   Interest Rate

            The rate of interest on each Loan for each of its Interest Periods
is the rate per annum determined by the Agent to be the aggregate of:-

            (a)   Applicable Margin;

            (b)   (i) in the case of all Loans other than a Sterling Loan, 
                  LIBOR; or

<PAGE>
                                       17


            9.2   Due dates

            Except as otherwise provided in this Agreement, accrued interest on
each Loan is payable by the Borrower on the last day of each Interest Period for
that Loan and also, if the Interest Period is longer than six months, at six
monthly intervals during that Interest Period.

            9.3   Default interest

            (a) If an Obligor fails to pay any amount payable by it under this
Agreement, it shall forthwith on demand by the Agent pay interest on the overdue
amount from the due date up to the date of actual payment, as well after as
before judgment, at a rate (the "default rate") determined by the Agent to be
one per cent. per annum above:

            (i) if the overdue amount is of principal and an Interest Period
      relative thereto is still current, the rate applicable to such overdue
      amount under Clause 9.1 (Interest rate) during such Interest Period; and

            (ii) in any other case, the rate which would have been payable if
      the overdue amount had, during the period of non-payment constituted a
      Loan in the currency of the overdue amount for such successive Interest
      Periods not exceeding three months of such duration as the Agent may
      determine (each a "Designated Interest Period").

            (b) The default rate will be determined by the Agent on each
Business Day or the first day of, or two Business Days before the first day of,
the relevant Designated Interest Period, as appropriate.

            (c) If the Agent determines that deposits in the currency of the
overdue amount are not at the relevant time being made available by the
Reference Banks to leading banks in the London interbank market, the default
rate will be determined by reference to the weighted average of the cost of
funds to the Banks from whatever sources they may select.

            (d) Default interest will be compounded at the end of each
Designated Interest Period.

            9.4   Notification

            The Agent shall promptly notify the Borrower, the Borrower's Agent
and each Bank of the determination of a rate of interest under this Agreement.

            10.   SELECTION OF OPTIONAL CURRENCIES

            10.1  Availability

            A Borrower may not request that a Loan be denominated in an Optional
Currency (other than an Agreed Optional Currency) unless the Agent has confirmed
to that Borrower that the Optional Currency is readily available and freely
transferable in the London foreign exchange market.
<PAGE>
                                       18


            10.2  Selection

            (a) The Borrower may select the currency of a Loan for an Interest
Period in either the relevant Request, or, if such Loan is outstanding, a notice
received by the Agent not later than 10.00 a.m. on the third (in the case of a
Loan to be denominated in Dollars or an Agreed Optional Currency during that
Interest Period) or the fifth (in the cases of a Loan to be denominated in a
currency other than Dollars or an Agreed Optional Currency during that Interest
Period) Business Day before the commencement of that Interest Period. The
Borrower may specify in any such notice whether that Loan is to be denominated
in more than one currency, and, if so, the amount in Dollars of each such
currency (being an integral multiple of an Original Dollar Amount of $5,000,000
or the balance of the Loan, if more).

            (b) If the Borrower fails to give a notice in respect of an
outstanding Loan in accordance with paragraph (a) above, that Loan shall remain
denominated for its next Interest Period in the same currency in which it is
then denominated.

            (c) Each part of a Loan which is to be denominated in a different
currency from any other part of that Loan shall be treated as a separate Loan.

            (d) The Borrower may not choose a currency if as a result the Loans
would be denominated at any one time in more than six currencies.

            (e) The Agent shall notify each Bank of the currency of each Loan
promptly after it is ascertained.

            10.3  Revocation of currency

            Notwithstanding Clause 10.1 (Availability), if before 10:00 a.m. on
the fourth Business Day before the commencement of an Interest Period, the Agent
receives notice from a Bank that:-

            (a) it is impracticable for the Bank to fund or make its
      participation in the Loan in the relevant Optional Currency (other than an
      Agreed Optional Currency) during that Interest Period; or

            (b) the use of the proposed Optional Currency (other than an Agreed
      Optional Currency) might contravene any law or regulation,

the Agent shall give notice to the Borrower, the Borrowers' Agent and to the
Banks to that effect before 11:00 a.m. on that day and, unless the Borrower, the
Borrowers' Agent and the Banks agree otherwise, the Loan shall be denominated in
Dollars during that Interest Period.

            11.   AMOUNT OF OPTIONAL CURRENCIES

            11.1  Drawdowns

            If a Loan is to be drawn down in an Optional Currency, the amount of
each Bank's participation in that Loan will be determined by converting into
that Optional Currency the Bank's participation in the Original Dollar Amount of
that Loan on the basis of the Agent's Spot Rate of Exchange three Business Days
before its Drawdown Date.
<PAGE>
                                       19


            11.2  Change of currency

            (a) If a Loan is to be continued during its next Interest Period in
a different currency (the "new currency") from that in which it is then
denominated, such Loan shall be repaid by the Borrower in full at the end of its
current Interest Period in the currency in which it is then denominated and,
subject to the terms of this Agreement, shall be re-advanced by the Banks
forthwith in the new currency.

            (b) If the new currency is Dollars, the amount of each Bank's
participation in that Loan will be its participation in the Original Dollar
Amount of that Loan for that Interest Period.

            (c) If the new currency is an Optional Currency, the amount of each
Bank's participation in that Loan will be determined by converting into the new
currency its participation in the Original Dollar Amount of that Loan on the
basis of the Agent's Spot Rate of Exchange three Business Days before the
commencement of that Interest Period.

            11.3  Same Optional Currency

            (a) If a Loan is to be continued during its next Interest Period in
the same Optional Currency as that in which it is denominated during its current
Interest Period, there shall be calculated the difference between the amount of
such Loan (in that Optional Currency) for the current Interest Period and for
the next Interest Period. The amount of such Loan for the next Interest Period
will be determined by notionally converting into that Optional Currency the
Original Dollar Amount of such Loan on the basis of the Agent's Spot Rate of
Exchange three Business Days before the commencement of that Interest Period.

            (b) At the end of the current Interest Period (but subject always to
paragraph (c) below):-

            (i) if the amount of such Loan for the next Interest Period is less
      than for the preceding Interest Period, the Borrower shall repay the
      difference; or

            (ii) if the amount of such Loan for the next Interest Period is
      greater, each Bank shall forthwith make available to the Agent for the
      Borrower its participation in the difference.

            (c) If the Agent's Spot Rate of Exchange for the next Interest
Period shows an appreciation or depreciation of the Optional Currency against
Dollars of less than five percent when compared with the Original Exchange Rate,
no amounts are payable in respect of the difference. In this Clause 11 (Amount
of Optional Currencies) "Original Exchange Rate" means the Agent's Spot Rate of
Exchange used for determining the amount of the Optional Currency for the
Interest Period which is the later of the following:-

            (i) the Interest Period during which such Loan was first denominated
      in that Optional Currency if such Loan has since then remained denominated
      in that Optional Currency; and
<PAGE>
                                       20


            (ii) the most recent Interest Period immediately prior to which a
      difference was required to be paid under this Clause 11.3.

            11.4  Prepayments and Repayments

            If a Loan is to be repaid or prepaid by reference to an Original
Dollar Amount, the amount actually to be repaid or prepaid in the relevant
Optional Currency shall be determined by applying to the relevant part of the
Original Dollar Amount to be repaid or prepaid the Agent's Spot Rate of Exchange
last used for determining the Optional Currency amount of that Loan under Clause
11 (amount of Optional Currencies) or, if applicable, the Original Exchange
Rate.

            11.5  Notification

            Except for Optional Currency amounts for a Loan to be drawn down in
an Agreed Optional Currency of which the Agent shall notify the Banks in
accordance with Clause 5.2 (Requests) the Agent shall notify the Banks, the
Borrower and the Borrowers' Agent of Optional Currency amounts (and the
applicable Agent's Spot Rate of Exchange) promptly after they are ascertained.

            12.   PAYMENTS

            12.1  Place

            All payments by an Obligor or a Bank under this Agreement shall be
made to the Agent to its account at such office or bank as it may, at least

Obligor or Bank for this purpose.

            12.2  Funds

            Payments under this Agreement to the Agent shall be made for value
on the due date at such times and in such funds as are customary at the time for
the settlement of transactions in the relevant currency in the place for
payment.

            12.3  Distribution

            (a) Each payment received by the Agent under this Agreement for
another Party shall, subject to paragraphs (b) and (c) below, be made available
by the Agent to that Party by payment (on the date and in the currency and funds
of receipt) to its account with such office or bank in the principal financial
center of the country of the relevant currency as it may notify to the Agent for
this purpose by not less than five Business Days' prior notice.

            (b) The Agent may apply any amount received by it for the Borrower
in or towards payment (on the date and in the currency and funds of receipt) of
any amount due from the Borrower under this Agreement or in or towards the
purchase of any amount of any currency to be so applied.

            (c) Where a sum is to paid to the Agent under this Agreement for
another Party, the Agent is not obliged to pay that sum to that Party until it
has established that it has actually received that sum. The Agent may, however,
assume that the sum has been 
<PAGE>
                                       21


paid to it in accordance with this Agreement, and, in reliance on that
assumption, make available to that Party a corresponding amount. If the sum has
not been made available but the Agent has paid a corresponding amount to another
Part, that Party shall forthwith on demand by the Agent refund the corresponding
amount together with interest on that amount from the date of payment to the
date of receipt, calculated at a rate determined by the Agent to reflect its
cost of funds.

            12.4  Currency

currency in which the Loan is denominated on its due date.

            (b) Interest is payable in the currency in which the relevant amount
in respect of which it is payable is denominated.

            (c) Amounts payable in respect of costs, expenses and taxes and the
like are payable in the currency in which they are incurred.

            (d) Any other amount payable under this Agreement is, except as
otherwise provided in this Agreement, payable in Dollars.

            12.5  Set-off and counterclaim

            All payments made by an Obligor under this Agreement shall be made
without set-off or counterclaim.

            12.6  Non-Business Days

            (a) If a payment under this Agreement is due on a day which is not a
Business Day, the due date for that payment shall instead be the next Business
Day in the same calendar month (if there is one) or the preceding Business Day
(if there is not).

            (b) During any extension of the due date for payment of any
principal under this Agreement interest is payable on that principal at the rate
payable on the original due date.

            12.7  Partial payments

            (a) If the Agent receives a payment insufficient to discharge all
the amounts then due and payable by the Obligors under this Agreement, the Agent
shall apply that payment towards the obligations of the Obligors under this
Agreement in the following order:

            (i) first, in or towards payment pro rata of any unpaid costs and
      expenses of the Agent under this Agreement;

            (ii) secondly, in or towards payment pro rata of any accrued
      interest due but unpaid under this Agreement;

            (iii) thirdly, in or towards payment pro rata of any principal due
      but unpaid under this Agreement; and
<PAGE>
                                       22


            (iv) fourthly, in or towards payment pro rata of any other sum due
      but unpaid under this Agreement.

            (b) The Agent shall, if so directed by all the Banks, vary the order
set out in sub-paragraphs (a)(ii) to (iv) above.

            (c) Paragraphs (a) and (b) above shall override any appropriation
made by an Obligor.

            13.   TAXES

            13.1  Gross-up

            All payments by an Obligor under the Finance Documents shall be made
without any deduction and free and clear of and without deduction for or on
account of any taxes (other than Taxes on Overall Net Income), except to the
extent that the Obligor is required by law to make payment subject to any taxes.
If any tax or amounts in respect of tax must be deducted, or any other
deductions for or on account of any taxes must be made, from any amounts payable
or paid by an Obligor, or paid or payable by the Agent to a Bank under the
Finance Documents (other than Taxes on Overall Net Income), the Obligor shall
(subject to clause 13.2 (c)) pay such additional amounts as may be necessary to
ensure that the relevant Bank receives a net amount equal to the full amount
which it would have received had payment not been made subject to tax.

            13.2  Forms

            (a) To the extent that at that time any Bank is entitled to complete
or partial, as the case may be, exemption from deduction or withholding for or
on account of any taxes with respect to all payments to be made by any Obligor
under the Finance Documents merely by completing certain forms, that Bank
agrees, upon request by such Obligor, to execute and deliver to such Obligor,
such forms, if they are required by law or are such as the Obligor may
reasonably request. Further, if COBE and/or REN becomes an Additional Borrower,
each Bank which is organised under the laws of a jurisdiction outside the US
hereby agrees (insofar as it can lawfully do so):

            (i) within 10 days after the date on which COBE and/or REN becomes
      an Additional Borrower to deliver to COBE and/or REN (as the case may be)
      and the Agent:-

                  (aa) for the office, if any, identified with such Bank's
            signature which is located in the United States of America, two
            accurate and complete, original signed copies of Internal Revenue
            Service Form 4224 or any successor thereto ("Form 4224"); or

                  (bb) for the office, if any, identified with such Bank's
            signature below which is located outside the United States of
            America, two accurate and complete, original signed copies of
            Internal Revenue Service Form 1001 or any successor thereto ("Form
            1001"),
<PAGE>
                                       23


                  in each case indicating that such Bank is on the date hereof
      entitled to receive all payments under this Agreement through such office
      free from withholding of US federal income tax; and

            (ii) before or promptly after the occurrence of any event (including
      the passage of time or designation of an Additional Borrower) requiring
      the delivery of an additional or replacement Form 4224 or 1001 to deliver
      to COBE and/or REN (as the case may be) and the Parent, upon the request
      of COBE, and/or REN), the Parent or the Agent, (if delivery of the same be
      lawful under then applicable law), two accurate and original signed copies
      of Form 4224 or 1001 in addition to or replacement for the forms
      previously delivered by such Bank claiming an exemption from withholding
      tax or the greatest reduction of withholding tax available under then
      applicable law.

            (b) Each Bank agrees that, to the extent any form claiming or
otherwise establishing complete or partial exemption from withholding and
deduction of taxes delivered under this Agreement is incomplete or incorrect in
any material respect when delivered or thereafter, such Bank shall execute and
deliver complete and correct replacement forms.

            (c) If a Bank fails to comply with paragraph (a) above, such Obligor
shall not be obliged to pay additional amounts under Clause 13.1 (Gross-up) in
respect of any deduction for or on account of taxes that would not have been
made had such Bank complied.

            13.3  Tax receipts

            All taxes required by law to be deducted or withheld by an Obligor
from any amounts paid or payable under the Finance Documents shall be paid by
the relevant Obligor when due and the Obligor shall, as soon as reasonably
practicable after the payment is made, deliver to the Agent for the relevant
Bank evidence satisfactory to that Bank (including all relevant tax receipts (or
similar evidence) or copies thereof) that the payment has been duly remitted to
the appropriate authority.

            13.4  Tax credits

            (a) If, following the payment by any Obligor of any additional
amounts under clause 13.1 (Gross-up), the Agent or any Bank shall determine that
it has received or been granted a credit against or remission for any taxes
payable by it, the Agent or such Bank shall reimburse such Obligor with such
amount as the Agent or such Bank shall in its absolute discretion certify to be
the proportion of such credit or remission (if any) as will leave the Agent or
such Bank (after such reimbursement) in no worse position than it would have
been in had the relevant deduction or withholding not been made. Such
reimbursement shall be made promptly upon the Agent or such Bank making any such
determination.

            (b)   Nothing in paragraph (a) above shall:

            (i) require the Agent or any Bank to disclose to any Obligor any
      details of its tax affairs;
<PAGE>
                                       24


            (ii) interfere with the right of the Agent or any Bank to arrange
      its tax affairs in whatever manner it thinks fit; and

            (iii) neither the Agent nor any Bank shall be under any obligation
      to claim relief in respect of any payment under Clause 13.1 (Gross-up) in
      priority to any other reliefs, claims or credits available to it.

            14.   MARKET DISRUPTION

            14.1  Absence of quotations

            If the Agent requests a quotation from the Reference Banks and a
Reference Bank does not supply an offered rate by 1.00 p.m. on a Rate Fixing
Day, the applicable LIBOR or EIBOR (as the case may be) shall, subject to Clause
14.2 (Market disruption), be determined on the basis of the quotation of the
other Reference Banks.

            14.2  Market disruption

            If, on or prior to a Rate Fixing Day:

            (a) the Agent requests a quotation from the Reference Banks and two
      Reference Banks do not supply an offered rate by 1.00 p.m. on a Rate
      Fixing Day; or

            (b) the Agent determines that adequate and fair means do not exist
      for ascertaining LIBOR or EIBOR (as the case may be); or

            (c) the Agent receives notification from Banks whose participations
      in a Loan exceed 50 per cent of that Loan that, in their opinion:-

                  (i) matching deposits are not available to them in the
            relevant interbank market in the ordinary course of business to fund
            their participations in that Loan for the relevant Interest Period;
            or

                  (ii) the cost to them of obtaining matching deposits in the
            relevant interbank market would be in excess of LIBOR or EIBOR (as
            the case may be) for the relevant Interest Period,

      the Agent shall promptly notify the Borrower and the Banks of the fact and
      that this Clause 14 (Market Disruption) is in operation.

            For the purposes of this Clause, "relevant interbank market" means:

                  (1) in the case of all Loans other than a Sterling Loan,
            London; and

                  (2) in the case of a Sterling Loan, such interbank market
            outside the United Kingdom as a Bank may reasonably select for the
            purpose of funding its participation.

            14.3  Suspension of drawdowns

            If a notification under Clause 14.2 (Market disruption) applies to a
Loan which has not been made, the Borrower's Agent may (by notice to the Agent)
elect that the Loan shall not be made.
<PAGE>
                                       25


            If the Borrowers' Agent does not so elect and such Loan is made,
Clause 14.4 (Alternative basis for outstanding Loans) shall apply thereto. If
the Borrowers' Agent does so elect, the Borrowers' Agent and the Agent shall,
within five Business Days of the relevant Rate Fixing Day, enter into
negotiations for a period of not more than 30 days with a view to agreeing an
alternative basis for the borrowing of that and any future Loan made while such
circumstances continue. Any alternative basis agreed shall be, with the prior
consent of all the Banks, binding on all the Parties.

            14.4  Alternative basis for outstanding Loans

            If a notification under Clause 14.2 (Market disruption) applies to a
Loan which is (or, by virtue of the Borrowers' Agent not making an election
under Clause 14.3 (Suspension of drawdowns), which has become) outstanding,
then, notwithstanding any other provision of this Agreement:-

            (a) within five Business Days of receipt of the notification, the
      Borrowers' Agent and the Agent shall enter into negotiations for a period
      of not more than 30 days with a view to agreeing an alternative basis for
      determining the rate of interest and/or funding applicable to that Loan
      and/or any other Loans denominated or to be denominated in the currency of
      that Loan;

            (b) any alternative basis agreed under paragraph (a) above shall be,
      with the prior consent of all the Banks, binding on all the Parties;

            (c) if no alternative basis is agreed, each Bank shall (through the
      Agent) certify on or before the last day of the Interest Period to which
      the notification relates an alternative basis for maintaining its
      participation in that Loan;

            (d) any such alternative basis may include an alternative method of
      fixing the interest rate, alternative Interest Periods or alternative
      currencies but it must reflect the cost to the Bank of funding its
      participation in the Loan from whatever sources it may reasonably select
      plus the Applicable Margin plus any applicable MLA Costs; and

            (e) each alternative basis so certified shall be binding on the
      Borrower, the Borrowers' Agent and the certifying Bank and treated as part
      of this Agreement.

            (f) Any alternative basis for the borrowing of any Loan shall cease
      as soon as reasonably practicable (as determined by the Agent) after the
      relevant circumstances have ceased to apply and the normal provisions of
      this Agreement shall apply thereafter.

            15.   INCREASED COSTS

            15.1  Increased costs

            (a) Subject to Clause 15.2 (Exceptions), the relevant Borrower or,
where the increased cost cannot be attributed to a particular Loan, the
Borrowers' Agent, shall within 5 Business Days of demand by a Finance Party to
the Borrowers' Agent pay to that Finance Party the amount of any increased cost
incurred by it as a result of:-

            (i) any change after the date of this Agreement in, or in the
      official interpretation or application of, any law or regulation; or
<PAGE>
                                       26


            (ii) compliance with any regulation made after the date of this
      Agreement.

(including any law or regulation relating to reserve asset, special deposit,
cash ratio, liquidity or capital adequacy requirements or any other form of
banking or monetary control).

            (b) In this Agreement "increased cost" means:-

            (i) an additional cost incurred by a Finance Party as a result of it
      having entered into, or performing, maintaining or funding its obligations
      under, this Agreement; or

            (ii) that portion of an additional cost incurred by a Finance Party
      in making, funding or maintaining all or any advances comprised in a class
      of advances formed by or including its participations in the Loans made or
      to be made under this Agreement as is attributable to it making, funding
      or maintaining those participations; or

            (iii) a reduction in any amount payable to a Finance Party or in the
      effective return to a Finance Party under this Agreement on its capital;
      or

            (iv) the amount of any payment made by a Finance Party, or the
      amount of any interest or other return foregone by a Finance Party, on or
      in relation to any amount received or receivable by that Finance Party
      from the Agent or an Obligor under this Agreement.

            (c) a Finance Party intending to make a claim under paragraph (a)
above shall, promptly upon its Facility Office becoming aware of an event by
reason of which it is entitled to do so and the possible results thereof, notify
the Agent, and the Agent shall promptly notify the Borrower and the Borrowers'
Agent of such event. For the purpose of this Clause 15.1 each Bank may in good
faith allocate or spread costs and/or losses among its assets and liabilities
(or any class thereof) on such basis as it considers appropriate.

            15.2  Exceptions

            Clause 15.1 (Increased costs) does not apply to any increased cost:-

            (a)   compensated for by the payment of any MLA Costs;

            (b)   provided for by the operation of Clause 13 (Taxes); or

            (c) attributable to any change in the rate or basis of calculation
      of Tax on Overall Net Income of a Bank (or tax on the overall net income
      of a division or branch of the Bank); or

            (d) incurred or suffered by a Bank as a consequence of the
      implementation of the matters set out in the report of the Basle Committee
      on Banking Regulations and Supervisory Practices dated July 1988 and
      entitled "International Convergence of Capital Measurement and Capital
      Standards" (as that report is in effect on the date of this Agreement).

                                       27


            16.   ILLEGALITY

            If it becomes unlawful in any jurisdiction for a Bank to give effect
to any of its obligations as contemplated by this Agreement or to fund or
maintain its participation in any Loan, then:-

            (a)   that Bank may notify the Borrowers' Agent through the Agent
      accordingly; and

            (b) (i) if so requested by that Bank through the Agent, the Borrower
      shall forthwith prepay that Bank's participation in all Loans made to it
      together with all other amounts payable by it to that Bank under this
      Agreement; and

                (ii) the Bank's undrawn Commitment shall forthwith be cancelled.

            17.   MITIGATION

            If, in respect of any Finance Party, circumstances arise which would
or would upon the giving of notice result in:

            (i) the prepayment of its share of any outstanding Loans and the
      cancellation of its Commitment pursuant to Clause 16 (Illegality); or

            (ii) the payment of additional amounts for its account pursuant to
      Clause 13.1 (Gross-up); or

            (iii) a claim for payment pursuant to Clause 15.1 (Increased Costs),

or if payments are being made to a finance Party pursuant to Clauses 13.1
(Gross-up) and 15.1 (Increased Costs), then, without in any way limiting,
reducing or otherwise qualifying the Obligors' obligations hereunder (and, in
particular, the Borrowers' obligations under any of the Clauses referred to in
sub-paragraphs (i), (ii), and (iii) above), such Finance Party shall take such
steps as such Finance Party in its bona fide opinion considers appropriate to
mitigate the effects of such circumstances including (if such Bank considers it
so appropriate) the transfer of its Facility Office to another jurisdiction or
the transfer of its rights and obligations hereunder to another financial
institution willing to participate herein PROVIDED THAT such Finance Party shall
be under no obligation to take any such steps if, in its bona fide opinion, such
steps would have an adverse effect upon its business, operations or financial
condition.

            18.   GUARANTEE

            18.1  Guarantee

            The Parent irrevocably and unconditionally:-

            (a) as principal obligor guarantees to each Finance Party prompt
      payment by each Borrower (other than the Parent) of all amounts payable by
      that Borrower under the Finance Documents;

            (b) undertakes with each Finance Party that whenever a Borrower
      (other than the Parent) does not pay any amount when due under or in
      connection with any Finance Document, the Parent shall forthwith on demand
      by the Agent pay that amount as if 
<PAGE>
                                       28


      the Parent instead of the relevant Borrower were expressed to be the
      principal obligor; and

            (c) agrees to indemnify each Finance Party on demand against any
      loss or liability suffered by it if any obligation guaranteed by the
      Parent is or becomes unenforceable, invalid or illegal.

            18.2  Continuing guarantee

            This guarantee is a continuing guarantee and will extend to the
ultimate balance of all sums payable by the Borrowers (other than the Parent)
under the Finance Documents, regardless of any intermediate payment or discharge
in whole or in part.

            18.3  Reinstatement

            (a) Where any discharge (whether in respect of the obligations of
any Borrower or any security for those obligations or otherwise) is made in
whole or in part or any arrangement is made on the faith of any payment,
security or other disposition which is avoided or must be restored on
insolvency, liquidation or otherwise without limitation, the liability of the
Parent under this Clause 18 (Guarantee) shall continue as if the discharge or
arrangement had not occurred.

            (b) Each Finance Party may concede or compromise any claim that any
payment, security or other dispositions liable to avoidance or restoration.

            18.4  Waiver of defences

            The obligations of the Parent under this Clause 18 (Guarantee) will
not be affected by any act, omission, matter or thing which, but for this
provision, would reduce release or prejudice any of its obligations under this
Clause 18 (Guarantee) or prejudice or diminish those obligations in whole or in
part, including (whether or not known to it or any Finance Party):-

            (a) any time or waiver granted to, or composition with, any Borrower
      (other than the Parent) or other person;

            (b) the taking, variation, compromise, exchange, renewal or release
      of, or refusal or neglect to perfect, take up or enforce, any rights
      against, or security over assets of, any Borrower (other than the Parent)
      or other person or any non-presentation or non-observance of any formality
      or other requirement in respect of any instrument or any failure to
      realise the full value of any security;

            (c) any incapacity or lack of powers, authority or legal personality
      of or dissolution or change in the members or status of a Borrower or any
      other person;

            (d) any variation (however fundamental) or replacement of a Finance
      Document or any other document or security so that references to that
      Finance Document in this Clause 18 (Guarantee) shall include each
      variation or replacement;

            (e) any unenforceability, illegality or invalidity of any obligation
      of any person under any Finance Document or any other document or
      security, to the intent that the Parent's obligations under this Clause 18
      (Guarantee) shall remain in full force and its 
<PAGE>
                                       29


      guarantee be construed accordingly, as if there were no unenforceability,
      illegality or invalidity; or

            (f) any postponement, discharge, reduction, non-provability or other
      similar circumstance affecting any obligation of any Borrower (other than
      the Parent) under a Finance Document resulting from any insolvency,
      liquidation or dissolution proceedings or from any law, regulation or
      order so that each such obligation shall for the purposes of the Parent's
      obligations under this Clause 18 (Guarantee) be construed as if there were
      no such circumstance.

            18.5  Immediate recourse

            The Parent waives any right it may have of first requiring any
Finance Party (or any trustee or agent on its behalf) to proceed against or
enforce any other rights or security or claim payment from any person before
claiming from the Parent under this Clause 18 (Guarantee).

            18.6  Appropriations

            Until all amounts which may be or become payable by the Borrowers
under or in connection with the Finance Documents have been irrevocably paid in
full, each Finance Party (or any trustee or agent on its behalf) may, after an
Event of Default which is continuing:-

            (a) refrain from applying or enforcing any other moneys, security or
      rights held or received by that Finance Party (or any trustee or agent on
      its behalf) in respect of those amounts, or apply and enforce the same in
      such manner and order as it sees fit (whether against those amounts or
      otherwise) and neither the Parent nor any Borrower shall be entitled to
      the benefit of the same; and

            (b) hold in a suspense account any moneys received from the Parent
      or on account of the Parent's liability under this Clause 18 (Guarantee),
      which shall bear interest at such Finance Party's best rate for comparable
      commercial deposits.

            18.7  Non-competition

            Until all amounts which may be or become payable by the Borrowers
under or in connection with the Finance Documents have been irrevocably paid in
full, the Parent shall not, by virtue of any payment or performance by it under
this Clause 18 (Guarantee):-

            (a) exercise any right to be subrogated to any rights, security or
      moneys held, received or receivable by any Finance Party (or any trustee
      or agent on its behalf) or exercise any right of contribution or indemnity
      in respect of any payment made or moneys received on account of the
      Parent's liability under this Clause 18 (Guarantee);

            (b) claim, rank, prove or vote as a creditor of any Borrower (other
      than the Parent) or its estate in compensation with any Finance Party (or
      any trustee or agent on its behalf); or

            (c) receive or exercise the right to claim any payment, distribution
      or security from or on account of any Borrower (other than the Parent), or
      exercise any right of set-off as against any such Borrower.
<PAGE>
                                       30


            The Parent shall hold in trust for and forthwith pay or transfer to
the Agent for the Finance Parties any payment or distribution or benefit of
security received by it contrary to this Clause 18.7.

            18.8  Additional security

            This guarantee is in addition to and is not in any way prejudiced by
any other security now or subsequently held by any Finance Party.

            19.   REPRESENTATIONS AND WARRANTIES

adverse effect on its ability to perform its obligations which (in the sole

arbitration or administrative proceedings (other than any frivolous or vexatious

            20.3  Information - Miscellaneous

      of all other assets disposed of after the date hereof and for so long as
      any Commitment or Loan is outstanding hereunder (not within sub-paragraphs
      (i)-(iv) above)) does not exceed 40 per cent. of Consolidated Total Assets
      (as measured in the latest published financial statements of the Group for
      the period immediately preceding the disposal).

            Each Finance Party (other than the Agent) irrevocably appoints the
Agent to act as its agent under and in connection with the Finance Documents,
and irrevocably authorises the Agent on its behalf to perform the duties and to
exercise the rights, powers and discretions that are specifically delegated to
it under or in connection with the Finance Documents, together with any other
incidental rights, powers and discretions. The Agent has only those duties which
are expressly specified in this Agreement, and those duties are solely of a
mechanical and administrative nature.

            22.2  Role of the Arranger

no obligations of any kind to any other Party under or in connection with any
Finance Document.

            22.3  Relationship

            The Relationship between the Agent and the other Finance Parties is
that of agent and principal only. Nothing in this Agreement constitutes the
Agent as trustee or fiduciary for any other Party or any other person and the
Agent need not hold in trust any moneys paid to it for a Party or be liable to
account for interest on those moneys.

            22.4  Majority Banks' directions

instructions of the Majority Banks in connection with the exercise of any right,
power or discretion or any matter not expressly provided for in this Agreement.
Any such instructions given by the Majority Banks will be binding on all the
Banks. In the absence of such instructions, the Agent may act as it considers to
be in the best interests of all the Banks.

            22.5  Delegation

            The Agent may act under the Finance Documents through its personnel
and agents whose acts shall be binding upon it.

      sufficiency of any Fiance Document or any other documents;

            (b) the collectability of amounts payable under any Finance
      Document; or

            (c) the accuracy of any statements (whether written or oral) made in
      or in connection with any Finance Document.

            22.7  Default

            (a) The Agent is not obliged to monitor or enquire as to whether or
not a Default has occurred. The Agent will not be deemed to have knowledge of
the occurrence of a Default. However, if the Agent receives notice from a Party
referring to this Agreement, describing the Default and stating that the event
is a Default, or if the officers of the Agent actually engaged in carrying out

            (b) The Agency may require the receipt of security satisfactory to
it from any other Finance party, whether by way of payment in advance or
otherwise, against any liability or loss which it will or may incur in taking
any proceedings or action arising out of or in connection with any Finance
Document before it commences those proceedings or takes that action.

            22.8  Exoneration

            (a) Without limiting paragraph (b) below, the Agent will not be
liable to any other Party for any action taken or not taken by it under or in
connection with any Finance Document, unless directly caused by its gross
negligence or willful misconduct.

            (b) No Party may take any proceedings against any officer, employee
or agent of the Agent in respect of any claim it might have against the Agent or
in respect of any act or omission of any kind (including gross negligence or
willful misconduct) by that officer, employee or agent in relation to any
Finance Document.

            22.9  Reliance

            The Agent may:-

            (a) rely on any notice or document believed by it to be genuine and

      person:

            (c) engage, pay for and rely on legal or other professional advisors

      representing a Party other than the Agent).

            22.10 Credit approval and appraisal

            Without affecting the responsibility of any Obligor for information
supplied by it or on its behalf in connection with any Finance Document, each
Bank confirms that it:-

            (a) has made its own independent investigation and assessment of the
      financial condition and affairs of each Obligor and its related entities
      in connection with its participation in this Agreement and has not relied
      exclusively on any information provided to it by the Agent or the Arranger
      in connection with any Finance Document; and

            (b) will continue to make its own independent appraisal of the
      creditworthiness of each Obligor and its related entities while any amount
      is or may be outstanding under the Finance Documents or any Commitment is
      in force.

            22.11 Information

            (a) The Agent shall promptly forward to the person concerned the
original or a copy of any document which is delivered to the Agent by a Party

document received by the Agent under Clause 4 (Conditions Precedent) upon the
request and at the expense of that Bank.

            (c) Except where this Agreement specifically provides otherwise, the
Agent is not obliged to review or check the accuracy or completeness of any
document it forwards to another Party.

            (d)   Except as provided above, the Agent has no duty:-

            (i) either initially or on a continuing basis to provide any Bank
      with any credit or other information concerning the financial condition or
      affairs of any Obligor or any related entity of any Obligor whether coming
      into its possession before, on or after the date of this Agreement; or

            (ii) unless specifically requested to do so by a Bank in accordance
      with this Agreement, to request any certificates or other documents from
      any Obligor.

            22.12 The Agent and the Arranger

            (a) If it is also a Bank, each of the Agent and the Arranger has the
same rights and powers under this Agreement as any other Bank and may exercise
those rights and powers as though it were not the Agent or the Arranger.

            (b)   Each of the Agent and the Arranger may:-

            (i) carry on any business with an Obligor or its related entities;

      involving, an Obligor or its related entities; and

            (iii) retain any profits or remuneration in connection with its
      activities under this Agreement or in relation to any of the foregoing.

            22.13 Indemnities

            (a) Without limiting the liability of any Obligor under the Finance
Documents, each Bank shall forthwith on demand indemnify the Agent for its
proportion of any liability or loss incurred by the Agent in any way relating to
or arising out of its acting as the Agent, except to the extent that the
liability or loss arises directly from the Agent's gross negligence or willful
misconduct.

            (b) A Bank's proportion of the liability set out in paragraph (a)
above will be the proportion which its participation in the Loans (if any) bears
to all the Loans on the date of the demand. If, however, there are no Loans
outstanding on the date of demand, then the proportion will be the proportion
which its Commitment bears to the Total Commitments at the date of demand or, if
the Total Commitments have then been cancelled, bore to the Total Commitments
immediately before being cancelled.

            22.14 Compliance

            (a) The Agent may refrain from doing anything which might, in its
opinion, constitute a breach of any law or regulation or be otherwise actionable
at the suit of any person, and may do anything which, in its opinion, is
necessary or desirable to comply with any law or regulation of any jurisdiction.

            (b) Without limiting paragraph (a) above, the Agent need not
disclose any information relating to any Obligor or any of its related entities
if the disclosure might, in the opinion of the Agent, constitute a breach of any
law or regulation or any duty of secrecy or confidentiality or be otherwise
actionable at the suit of any person.

            22.15 Resignation of the Agent

            (a) Notwithstanding its irrevocable appointment, the Agent may
resign by giving notice to the Banks and the Obligors, in which case the Agent
may forthwith appoint one of its Affiliates as successor Agent or, failing that,
the Majority Banks may appoint a successor Agent.

            (b) If the appointment of a successor Agent is to be made by the
Majority Banks but they have not, within 30 days after notice of resignation,
appointed a successor Agent which accepts the appointment, the Agent may appoint
a successor Agent.

            (c) The resignation of the Agent and the appointment of any
successor Agent will both become effective only upon the successor Agent
notifying all the Parties that it accepts its appointment. On giving the
notification, the successor Agent will succeed to the position or the Agent and
the term "Agent" will mean the successor Agent.

                                       47


            (i) that Obligor shall indemnify that Finance Party as an
      independent obligation against any loss or liability arising out of or as
      a result of the conversion;

            (ii) if the amount received by that Finance Party, when converted
      into the contractual currency at a market rate in the usual course of its
      business is less than the amount owed in the contractual currency, the

under any Finance Document, any amount repaid or prepaid or any Loan.

            26.3  No restrictions on Obligors

            27.1  Accounts

Agreement are prima facie evidence of the matters to which they relate.

            27.2  Certificates and determinations

            28.   AMENDMENTS AND WAIVERS

            28.1  PROCEDURE

            (a) Subject to Clause 28.3 (Exceptions), any term of the Finance

Banks, an amendment or waiver to which they have agreed.

            (b) The Agent shall promptly notify the other Parties of any

            28.3  Waivers and Remedies Cumulative

            The rights of each Finance Party under the Finance Documents:-

            (a) may be exercised as often as necessary;

            (b) are cumulative and not exclusive of its rights under the general
      law; and

            (c) may be waived only in writing and specifically.

            Delay in exercising or non-exercise of any such right is not a
waiver of that right.

            29.   CHANGES TO THE PARTIES

            29.1  Transfers by Obligors

            No Obligor may assign, transfer, novate or dispose of any of, or any
interest in, its rights and/or obligations under this Agreement.

            29.2  Transfers by Banks

            (a) A Bank (the "Existing Bank") may, with the prior written consent
of the Borrowers' Agent (such consent not to be unreasonably withheld), at any
time assign, transfer or novate any of its rights and/or obligations under this
Agreement to another bank or financial institution (the "New Bank").

            Provided that each Bank (so long as it remains a Bank hereunder)
shall, subject to the other terms of this Agreement, continue to maintain a
Commitment and/or participation in the Facility in an aggregate amount at least
equal to US$10,000,000 (or its equivalent) hereunder.

            (b) A transfer of obligations will be effective only if either:-

            (i) the obligations are novated in accordance with Clause 29.3
      (Procedure for novations); or

            (ii) the New Bank confirms to the Agent and the Obligors that it
      undertakes to be bound by the terms of this Agreement as a Bank in form
      and substance satisfactory to the Agent. On the transfer becoming
      effective in this manner the Existing Bank shall be relieved of its
      obligations under this Agreement to the extent that they are transferred
      to the New Bank.

            (c) Nothing in this Agreement restricts the ability of a Bank to
      sub-contract an obligation if that Bank remains liable under this
      Agreement for that obligation.

            (d) On each occasion an Existing Bank assigns, transfer or novates
      any of its rights and/or obligations under this Agreement, the New Bank
      shall, on the date the assignment, transfer and/or novation takes effect,
      pay to the Agent for its own account a fee of $500.

            (e) An Existing Bank is not responsible to a New Bank for:-
<PAGE>
                                       50


                  (i) the execution, genuineness, validity, enforceability or
            sufficiency of any Finance Document or any other document;

                  (ii) the collectability of amounts payable under any Finance
            Document; or

                  (iii) the accuracy of any statements (whether written or oral)
            made in or in connection with any Finance Document.

            (f) Each New Bank confirms to the Existing Bank and the other
      Finance parties that it:-

                  (i) has made its own independent investigation and assessment
            of the financial condition and affairs of each Obligor and its
            related entities in connection with its participation in this
            Agreement and has not relied exclusively on any information provided
            to it by the Existing Bank in connection with any Finance Document;
            and

                  (ii) will continue to make its own independent appraisal of
            the creditworthiness of each Obligor and its related entities while
            any amount is or may be outstanding under this Agreement or any
            Commitment is in force.

            (g) Nothing in any Finance Document obliges an Existing Bank to:-

                  (i) accept a re-transfer from a New Bank of any of the rights
            and/or obligations assigned, transferred or novated under this
            Clause; or

                  (ii) support any losses incurred by the New Bank by reason of
            the non-performance by the Borrower of its obligations under this
            Agreement or otherwise.

            (h) Any reference in this Agreement to a Bank includes a New Bank
      but excludes a Bank if no amount is or may be owed to or by it under this
      Agreement and its Commitment has been cancelled or reduced to nil.

            29.3  Procedure for novations

            (a)   A novation is effected if:-

            (i) the Existing Bank and the New Bank deliver to the Agent a duly
      completed certificate substantially in the form of Part I of Schedule 5
      (a "Novation Certificate"); and

            (ii)  the Agent executes it.

            (b) Each Party (other than the Existing Bank and the New Bank)
      irrevocably authorises the Agent to execute any duly completed Novation
      Certificate on its behalf.

            (c) To the extent that they are expressed to be the subject of the
      novation in the Novation Certificate:-
<PAGE>
                                       51


                  (i) the Existing Bank and the other Parties (the "existing
            Parties") will be released from their obligations to each other (the
            "discharged obligations");

                  (ii) the New Bank and the existing Parties will assume
            obligations towards each other which (subject to Clause 39.5 (No
            extra cost) differ from the discharged obligations only insofar as
            they are owed to or assumed by the New Bank instead of the Existing
            Bank;

                  (iii) the rights of the Existing Bank against the existing
            Parties and vice versa (the "discharged rights") will be cancelled;
            and

                  (iv) the New Bank and the existing Parties will acquire rights
            against each other which (subject to Clause 29.5 (No extra cost))
            differ from the discharged rights only insofar as they are
            exercisable by or against the New Bank instead of the Existing Bank,

all on the date of execution of the Novation Certificate by the Agent or, if
later, the date specified in the Novation Certificate.

            29.4  Reference Banks

            If a Reference Bank (or, if a Reference Bank is not a Bank, the Bank
of which it is an Affiliate) ceases to be a Bank, the Agent shall (in
consultation with the parent) appoint another Bank or an Affiliate of a Bank to
replace the Reference Bank.

            29.5  No extra cost

            If:-

            (a) any assignment or transfer of all or any part of the rights or
      obligations of a Bank pursuant to Clause 29; or

            (b) any change in a Bank's Facility Office,

results, as a result of laws or regulations in force or the subject of a formal
government proposal at that time, in amounts becoming due at that time under
Clauses 13.1 (Gross-up) or 15 (Increased Costs), then the assignee, transferee,
New Bank or Bank, as the case may be, shall be entitled to receive those amounts
only to the extent that the assignor, transferor, Existing Bank or Bank, as the
case may be, would have been so entitled had there been no such assignment,
transfer, or change in Facility Office.

            30.   DISCLOSURE OF INFORMATION

            (a) A Bank may disclose to one of its Affiliates or (subject to
prior notification to the Borrower of the identity of such person) any person
with whom it is proposing to enter, or has entered into, any kind of transfer,
participation or other agreement in relation to this Agreement:-

            (i) a copy of any Finance Document; and

            (ii) any information which that Bank has acquired under or in
      connection with any Finance Document.

            (b) A Finance Party shall keep confidential any and all information
(except information which is publicly available or in respect of which
disclosure is required by law or regulation) relating to the Group or a member
of the Group which is disclosed to the Finance Paty for the purpose of or in
connection with any Finance Document.

            31.   SET-OFF

            A Finance Party may set off any amount due and owed by an Obligor
under this Agreement (to the extent beneficially owned by that Finance Party)
against any obligation (whether or not matured) owed by that Finance Party to
that Obligor, regardless of the place of payment, booking branch or currency of
either obligation. If the obligations are in different currencies, the Finance
Party may convert either obligation at a market rate of exchange in its usual
course of business for the purpose of the set-off.

            32.   PRO RATA SHARING

            32.1  Redistribution

            If any amount owing by an Obligor under this Agreement to a Finance
Party (the "recovering Finance Party") is discharged by payment, set-off or any
other manner other than through the Agent in accordance with Clause 12
(Payments) ("recovery"), then:-

            (a) the recovering Finance Party shall, within three Business Days,
      notify details of the recovery to the Agent;

            (b) the Agent shall determine whether the recovery is in excess of
      the amount which the recovering Finance Party would have received had the
      recovery been received by the Agent and distributed in accordance with
      Clause 12 (Payments);

            (c) subject to Clause 32.3 (Exception), the recovering Finance Party
      shall within three Business Days of demand by the Agent pay to the Agent
      an amount (the "redistribution") equal to the excess;

            (d) the Agent shall treat the redistribution as if it were a payment
      by the Obligor concerned under Clause 12 (Payments) and shall pay the
      redistribution to the Finance Parties (other than the recovering Finance
      Party) in accordance with Clause 12.7 (Partial payments); and

            (e) after payment of the full redistribution, the recovering Finance
      Party will be subrogated to the portion of the claims paid under paragraph
      (d) above and that Obligor will owe the recovering Finance Party a debt
      which is equal to the redistribution, immediately payable and of the type
      originally discharged.

            32.2  Reversal of redistribution

            If under Clause 32.1 (Redistribution):-
<PAGE>
                                       53


            (a) a recovering Finance Party must subsequently return a recovery,
      or an amount measured by reference to a recovery, to an Obligor; and

            (b) the recovering Finance Party has paid a redistribution in
      relation to that recovery,

each Finance Party shall, within three Business Days of demand by the recovering
Finance Party through the Agent, reimburse the recovering Finance Party all or
the appropriate portion of the redistribution paid to that Finance Party.
Thereupon, the subrogation in Clause 32.1(e) (Redistribution) will operate in
reverse to the extent of the reimbursement.

            32.3  Exception

            (a) A recovering Finance Party need not pay a redistribution to the
extent that it would not, after the payment, have a valid claim against the
Obligor concerned in the amount of the redistribution pursuant to Clause 32.1(e)
(Redistribution).

            (b) A Finance Party is not entitled to participate in a
redistribution if the redistribution results from the proceeds of a judicial
enforcement order obtained by the recovering Finance Party and the other Finance
Party had adequate notice of and opportunity to participate in the proceedings
concerned but did not do so.

            33.   SEVERABILITY

            If a provision of any Finance Document is or becomes illegal,
invalid or unenforceable in any jurisdiction that shall not affect:-

            (a) the validity or enforceability in that jurisdiction of any other
      provision of the Finance Documents; or

            (b) the validity or enforceability in other jurisdictions of that or
      any other provision of the Finance Documents.

agrees that the courts of England are to have jurisdiction to settle any
disputes which may arise out of or in connection with any Finance Document and
that, accordingly, any legal action or proceedings arising out of or in
connection with any Finance Document ("Proceedings") may be brought in those
courts and each Obligor irrevocably submits to the jurisdiction of those courts.

            37.2  Submission to Swedish Courts

            Without prejudice to Clause 37.1 (Submission to English Courts) each
Obligor further irrevocably agrees that any Proceedings may be brought in the
courts of Sweden and submits to the non-exclusive jurisdiction of such courts.

            37.3  Service of process

            Without prejudice to any other mode of service, each Obligor:-

            (a) irrevocably appoints:

            (b) agrees that as a judgment or order, other than an interim

                                  SCHEDULE 3

                          CALCULATION OF THE MLA COST

(a) The MLA Cost for a Loan maintained in Sterling for each of its Interest
Periods is calculated in accordance with the following formula:-

      [BY + L(Y-X) + S(Y-Z)]/[100 - (B + S)]   % per annum = MLA Cost
              

where on the day of application of the formula:

B     is the percentage of the Agent's eligible liabilities which the Bank of
      England requires the Agent to hold on a non-interest-bearing deposit
      account in accordance with its cash ratio requirements;

Y     is the rate at which Sterling deposits are offered by the Agent to leading
      banks in the London interbank market at or about 11.00 a.m. on that day
      for the relevant period;

L     is the percentage of eligible liabilities which the Bank of England
      requires the Agent to maintain as secured money with members of the London
      Discount Market Association and/or as secured call money with certain
      money brokers and gilt-edged primary market makers;

X     is the rate at which secured Sterling deposits may be placed by the Agent
      with members of the London Discount Market Association and/or as secured
      call money with certain money brokers and gilt-edged primary market makers
      at or about 11.00 a.m. on that day for the relevant period;

S     is the percentage of the Agent's eligible liabilities which the Bank of
      England requires the Agent to place as a special deposit; and

Z     is the interest rate per annum allowed by the Bank of England on special
      deposits.

(b)   For the purposes of this Schedule 3:-

            (i) "eligible liabilities" and "special deposits" have the meanings
      given to them at the time of application of the formula by the Bank of
      England; and

            (ii) "relevant period" in relation to each Interest Period, means:-

                  (A) if it is 3 months or less, that Interest Period; or

                  (B) if it is more than 3 months, each successive period of 3
            months and any necessary shorter period comprised in that Interest
            Period.
<PAGE>
                                       61


(c) In the application of the formula, B, Y, L, X, S and Z are included in the
formula as figures and not as percentages, e.g., if B = 0.5% and Y = 15%, BY is
calculated as 0.5 x 15.

(d) (i) The formula is applied on the first day of each relevant period
comprised in the relevant Interest Period.

      (ii) Each rate calculated in accordance with the formula is, if necessary,
rounded upward to four decimal places.

(e) If the Agent determines that a change in circumstances has rendered, or will
render, the formula inappropriate, the Agent (after consultation with the Banks
and the Borrower's Agent) shall notify the Banks and the Borrowers' Agent of the
manner in which the MLA Cost will subsequently be calculated. The manner of
calculation so notified by the Agent shall, in the absence of manifest error, be
binding on all the Parties.

such Advance that in such event such Advance should be denominated in dollars in
which case such Advance shall be made in dollars in an amount equal to the
Dollar Amount relating to such Notice of Drawdown.

6.6 If the Borrower requests an Advance in accordance with the preceding
provisions of this Clause 6 and, on the proposed date for the making of such
Advance:

            (i)   neither of the events mentioned in Clauses 8(i) and 8(ii)
                  shall have occurred;

            (ii)  the Dollar Amount of such Advance does not exceed the
                  Available Facility; and

            (iii) either:

<PAGE>

                  (a)   no Event of Default or Potential Event of Default has
                        occurred; and

                  (b)   the representations set out in Clause 15 (except
                        sub-Clauses 15.2(v), (viii) and (xiv)) are true on and
                        as of the proposed date for the making of such Advance

                        or each of the Banks agrees (notwithstanding any matter
                        mentioned at (a) or (b) above) to participate in the
                        making of such Advance.

Except as otherwise provided herein, such Advance will be made in accordance
with the provisions [____________] in dollars in an amount equal to the Dollar
Amount requested or, if such Advance is to be denominated in an Optional
Currency, in an amount which is the equivalent in such Optional Currency of the
Dollar Amount requested, calculated as at the business day prior to the
Quotation [_________] such Advance (such equivalent amount to be notified by the
Agent to the Banks promptly [__________] determination).

Each Bank will participate through its Facility Office in each Advance made
pursuant to this [_________] in the proportion borne by its Available Commitment
to the Available Facility immediately [__________] the making of that Advance.

If a Bank's Commitment is reduced in accordance with the terms hereof after the
Agent has received the Notice of Drawdown for an Advance and such reduction was
not taken into account pursuant to Clause 6.2(iii)(a), then both the Dollar
Amount and the actual amount of that Advance will be reduced accordingly.

7.    Interest

7.1 On the Repayment Date relating to each Advance the Borrower shall pay
accrued interest on that Advance.

7.2 The rate of interest applicable to an Advance from time to time during its
Term shall be the rate per annum which is the sum of the Margin and LIBOR
applicable to such Advance on the Quotation Date therefor.

8.    Market Disruption and Alternative Interest Rates

If, in relation to any Advance:

            (i)   the Agent determines that at or about 11:00 a.m. on the
                  Quotation Date for the Term in respect of such Advance no
                  rates are quoted on page 3740 or, as applicable, page 3750 of
                  the Telerate screen for the relevant currency (or such other
                  page as may replace such page) and none or only one of the
                  Reference Banks was offering to prime banks in the London
                  Interbank Market deposits in dollars for the proposed duration
                  of such Term; or

            (ii)  before the close of business in London on the Quotation Date
                  for such Term the Agent has been notified by a Bank or each of
                  a group of Banks to whom in aggregate thirty-five per cent. or
                  more of the Dollar Amount of the Loan is (or, if an Advance
                  were then made, would be) owed that LIBOR as determined by the
                  Agent does not accurately reflect the cost to it of obtaining
                  such deposits,

then, notwithstanding the provisions of Clause 6:

            (a)   the Agent shall notify the other parties hereto of such event;

            (b)   such Advance shall not be made; and

            (c)   if the Agent or the Borrower so requires, within five days of
                  such notification the Agent and the Borrower shall enter into
                  negotiations with a view to agreeing a substitute basis for
                  determining the rates of interest which may be applicable to
                  Advances in the future and any such substitute basis that is
                  agreed shall take effect in accordance with its terms and be
                  binding on each party hereto Provided that the Agent may not
                  agree any such substitute basis without the prior consent of
                  each Bank.

Date relating thereto.

9.2 The Borrower shall not repay all or any part of any Advance outstanding
hereunder except at the times and in the manner expressly provided herein but,

amount repaid.

10.   Cancellation

10.1 The Borrower may, by giving to the Agent not less that thirty (30) days'

amount equal to the Available Facility) of the Total Commitments. Any such
cancellation shall reduce the Commitment of each Bank rateably.

shall be irrevocable and shall specify the date upon which such cancellation is
to be made and the amount of such cancellation.

Clause 13.1, the Borrower may, within thirty days thereafter and by not less
that fifteen days' prior written notice to the Agent (which notice shall be
irrevocable), cancel such Bank's Commitment whereupon such Bank shall cease to
be obliged to participate in further Advances and its Commitment shall be
reduced to zero.

                            CHANGES IN CIRCUMSTANCES

11.   Taxes

11.1 All payments to be made by either of the Obligors to any person hereunder
shall be made free and clear of and without deduction for or on account of any
applicable tax unless such Obligor is required to make such a payment subject to
the deduction or withholding of tax, in which case the sum payable by such
Obligor in respect of which such deduction or withholding is required to be made
shall be increased to the extent necessary to ensure that, after the making of
the required deduction or withholding, such person receives and retains (free
from any liability in respect of any such deduction or withholding) a net sum
equal to the sum which it would have received and so retained had no such
deduction or withholding been made or required to be made.

11.2 Without prejudice to the provisions of Clause 11.1, if any person or the
Agent on its behalf is required to make any payment on account of any applicable
tax (not being a tax imposed on the net income of its Facility Office by the
jurisdiction in which it is incorporated or in which its Facility Office is
located) or otherwise on or in relation to any sum received or receivable
hereunder by such person or the Agent on its behalf (including, without
limitation, any sum received or receivable under this Clause 11) or any
liability in respect of any such payment is asserted, imposed, levied or
assessed against such person or the Agent on its behalf, the Borrower shall,
upon demand of the Agent, promptly indemnify such person against such payment or
liability, together with any interest, penalties and expenses payable or
incurred in connection therewith.

11.3 A Bank intending to make a claim pursuant to Clause 11.2 shall notify the
Agent of the event by reason of which it is entitled to do so, whereupon the
Agent shall notify the Borrower thereof Provided that nothing herein shall
require such Bank to disclose any confidential information relating to the
organisation of its affairs.

11.4 If a Bank receives the benefit of a tax credit or an allowance resulting
from a payment which includes an additional amount paid by an Obligor under
Clause 11.1 or if it is otherwise left in a position which is more favourable to
it than would be the case if such withholding or deduction and resultant
additional payment by the Obligor had not been made, it shall (to the extent
that it can do so without prejudice to the retention of such credit or allowance
and to the extent that it is not unlawful or contrary to any official directive
for it so to do) pay to the relevant Obligor such part of that benefit as is, in
the sole opinion of that Bank, attributable to the withholding or deduction
giving rise to the payment of that additional amount, provided that such Bank
shall;

      (a)   be the sole judge of the amount of any such benefit to be so paid to
            the relevant Obligor and of the date on which it is received;


                                       15
<PAGE>

      (b)   have an absolute discretion as to the order and manner in which it
            employs or claims tax credits and allowances to it or as to the
            manner in which it arranges its tax affairs; and

      (c)   not be obliged to disclose to any Obligor or any other person any
            information regarding its tax affairs or tax computations.

12.   Tax Receipts and Mitigation

12.1 If, at any time, either of the Obligors is required by law to make any
deduction or withholding from any sum payable by it hereunder (or if thereafter
there is any change in the rates at which or the manner in which such deductions
or withholdings are calculated), such Obligor shall promptly notify the Agent.

12.2 If either of the Obligors makes any payment hereunder in respect of which
it is required to make any deduction or withholding, it shall pay the full
amount required to be deducted or withheld to the relevant taxation or other
authority within the time allowed for such payment under applicable law and
shall deliver to the Agent for each Bank, within thirty days after it has made
such payment to the applicable authority, and original receipt (or a certified
copy thereof) issued by such authority evidencing the payment to such authority
of all amounts so required to be deducted or withheld in respect of that Bank's
share of such payment.

12.3 If in respect of any Bank, circumstances arise which would or would upon
the giving of notice result in (i) an increase in the amount of any payment to
be made to it for its account pursuant to Clause 11.1 or (ii) a claim for
indemnification pursuant to Clause 11.2 then, without in any way limiting,
reducing or otherwise qualifying the obligations of the Obligors under this
Agreement, such Bank shall, promptly upon its Facility Office becoming aware of
the same and the possible results thereof, notify the Agent thereof and, in
consultation with the Agent and the Borrower, take such steps as such Bank in
its bona fide opinion considers appropriate to mitigate the effects of such
circumstance including the transfer of its Facility Office to another
jurisdiction or the transfer of its rights and obligations hereunder to another
bank willing to participate in the Facility Provided that such Bank shall be
under no obligation to take any such steps if, in the bona fide opinion of such
Bank, such steps would or might have an adverse effect upon its, or its holding
company's business, operations or financial condition or tax affairs.

13.   Increased Costs

13.1 If, by reason of (i) any change in law after the date hereof or in its
interpretation or administration and/or (ii) compliance with any request from or
requirement (whether or not having the force of law) of any central bank or
other fiscal, monetary or other authority made or imposed after the date hereof
(including, without limitation, a request or requirement which affects the
manner in which a Bank or any holding company of such Bank is required to or
does maintain capital resources having regard to such Bank's obligations
hereunder and to amounts owing to it hereunder):

      (a)   a Bank or any holding company of such Bank incurs a cost as a result
            of such Bank's having entered into and/or performing its obligations
            under this


                                       16
<PAGE>

            Agreement and/or assuming or maintaining a commitment under this
            Agreement and/or making one or more advances hereunder;

      (b)   a Bank or any holding company of such Bank is unable to obtain the
            rate of return on its overall capital which it would have been able
            to obtain for such Bank having entered into and/or performing its
            obligations and/or assuming or maintaining a commitment under this
            Agreement;

      (c)   there is any increase in the cost to a Bank or any holding company
            of such Bank of funding or maintaining all or any of the advances
            comprised in a class of advances formed by or including the advances
            made or to be made by such Bank hereunder; or

      (d)   a Bank or any holding company of such Bank becomes liable to make
            any payment on account of tax or otherwise (not being a tax imposed
            on the net income of such Bank's Facility Office by the jurisdiction
            in which it is incorporated or in which its Facility Office is
            located) on or calculated by reference to the amount of the advances
            made or to be made by such Bank hereunder and/or to any sum received
            or receivable by it hereunder,

then the Borrower shall, from time to time on demand of the Agent, promptly pay
to the Agent for the account of that Bank amounts sufficient to indemnify that
Bank or any such holding company against, as the case may be, (1) such cost, (2)
such reduction in such rate of return (or such proportion of such reduction as
is, in the opinion of that Bank, attributable to its obligations hereunder), (3)
such increased cost (or such proportion of such increased cost as is, in the
opinion of that Bank, attributable to its funding or maintaining advances
hereunder), or (4) such liability.

13.2 A Bank intending to make a claim pursuant to Clause 13.1 shall no later
than 3 months after becoming aware of the event by reason of which it is
entitled to make such claim in relation to any payments notify the Agent and the
Borrower of the event by reason of which it is entitled to do so Provided that
nothing herein shall require such Bank to disclose any confidential information
relating to the organisation of its affairs.

14.   Illegality

If, at any time, it is unlawful for a Bank to make, fund or allow to remain
outstanding all or any of the Advances made or to be made by it hereunder, then
that Bank shall, promptly after becoming aware of the same and where the
illegality has not yet occurred notify the Borrower through the Agent and that
Bank and the Agent shall negotiate in good faith with the Borrower with a view
to agreeing substitute terms for participating in the Facility on a lawful
basis. Where the illegality has occurred the relevant Bank shall deliver to the
Borrower through the Agent a certificate to that effect and:

            (i)   such Bank shall not thereafter be obliged to make advances
                  hereunder and the amount of its Commitment shall be
                  immediately reduced to zero; and


                                       17
<PAGE>

            (ii)  if the Agent on behalf of such Bank so requires, the Borrower
                  shall on such date as the Agent shall have specified repay
                  such Bank's share of any outstanding Advances together with
                  accrued interest thereon and all other amounts owing to such
                  Bank hereunder.

15.2  Each of the Obligors further represents that:

            (i)   no member of the Group has taken any corporate action nor have
                  any other steps been taken or legal proceedings been started

                  dissolution or administration or for the appointment of a
                  receiver, administrator, administrative receiver, trustee or

                  been started or threatened;

            (iv)  the Original Financial Statements of the Borrower and the
                  Guarantor were prepared in accordance with accounting

<PAGE>

                  more than 10 per cent. the amounts disclosed in the Original

                  material adverse change in the business, assets or financial
                  condition of either Obligor, which change would give
                  sufficient ground to conclude that either Obligor may not or
                  will be unable to, perform or observe its respective
                  obligations hereunder;

                  circumstances that have not been disclosed to the Agent, the
                  Arrangers and the Banks and which might, if disclosed,
                  adversely affect the decision of a person considering whether
                  or not to provide finance to the Borrower or to provide such
                  finance against the security of a guarantee issued by the

                  such as that carried on by such member of the Group whose
                  practice is not to self insure;

                  and of the results of its (or, as the case may be, the
                  Group's) operations during such period; and

            (iii) each set of financial statements delivered by it pursuant to

                  financial years, then the next following, and each subsequent,

                  effect all authorisations, approvals, licenses and consents
                  required in or by the laws and regulations of its jurisdiction
                  of incorporation to enable it lawfully to enter into and
                  perform its obligations under this Agreement or to ensure the
                  legality, validity, enforceability or admissibility in
                  evidence in its jurisdiction of incorporation of this
                  Agreement;

            (ii)  after the delivery of any Notice of Drawdown and before the

                  reasonably be expected to result in any of the representations
                  contained in Clause 15 being untrue at or before the time of
                  the proposed making of such Advance;

            (iii) ensure that each Obligor shall promptly inform the Agent of
                  the occurrence of any Event of Default or Potential Event of
                  Default (and of the steps, if any, being taken to remedy it)
                  and, upon receipt of a written request to that effect from the
                  Agent, confirm to the Agent that, save as previously notified
                  to the Agent or as notified in such 


                                       24
<PAGE>

                  confirmation, no Event of Default or Potential Event of
                  Default has occurred; and

            (iv)  ensure that at all times the claims of the Agent, the
                  Arrangers and the Banks against it under this Agreement rank
                  at least pari passu with the claims of all its other unsecured
                  creditors save those whose claim are preferred by any
                  bankruptcy, insolvency, liquidation or other similar laws of
                  general application.

                        substantially all of its current business

                  if such merger or cessation, as the case may be, would result
                  in a material change of circumstances which might adversely
                  affect the ability of either Obligor to perform its
                  obligations hereunder; and

            (ii)  neither the Guarantor nor a Principal Subsidiary shall (save
                  in the ordinary course of business) make any loans, grant any
                  credit or give any guarantee or indemnity, provide any other
                  financial assistance to or for the benefit of any member of

17.3 Each of the Obligors shall ensure that neither the Guarantor nor any
Principal Subsidiary shall, without the written prior consent of an Instructing
Group, at any time while any amounts remain outstanding from the Borrower or, as
the case may be, may be due from the Guarantor, create or permit to subsist any
encumbrance over all or any of its present or future revenues or assets as
security for any indebtedness of any person other than:

                  subsequently increased;

            (ii)  any encumbrance arising solely by operation of law which
                  arises in the ordinary course of business and which is

                  be reduced to zero.

18.2 If, pursuant to Clause 18.1, the Agent declares the Advances to be due and
payable on demand of the Agent, then, and at any time thereafter, the Agent may
(and, if so instructed by an Instructing Group, shall) by written notice to the
Borrower call for repayment of the Advances on such date as it may specify in
such notice (whereupon the same shall become due and payable on such date
together with accrued interest thereon and any other sums then owed by the
Borrower hereunder) or withdraw its declaration with effect from such date as it
may specify in such notice.

18.3 If, pursuant to Clause 18.1(a), the Agent declares the Advances to be due
and payable on demand, the Term in respect of any such Advance shall, if the
Agent subsequently demands payment before the scheduled Repayment Date in
respect of such Advance, be deemed (except for the purposes of Clause 21.4) to
be of such length that it ends on the date that such demand is made.

                                    GUARANTEE

19.   Guarantee

The Guarantor hereby irrevocably and unconditionally:

            (i)   guarantees to the Agent, the Arrangers and the Banks the due
                  and punctual observance and performance of all the terms,
                  conditions and covenants on the part of the Borrower contained
                  in this Agreement and agrees to pay to the Agent from time to
                  time on demand any and every sum or sums of money which the
                  Borrower shall at any time be liable to pay to the Agent, the
                  Arrangers and the Banks or any of them under or pursuant to
                  this Agreement and which shall not have been paid at the time
                  such demand is made; and

            (ii)  agrees as a primary obligation to indemnify the Agent, the
                  Arrangers and the Banks from time to time on demand by the
                  Agent from and against any loss incurred by the Agent, the
                  Arrangers and the Banks or any of them as a result of any of
                  the obligations of the Borrower under or pursuant to this
                  Agreement being or becoming void, voidable, unenforceable or
                  ineffective as against the Borrower for any reason whatsoever,
                  whether or not known to the Agent, the Arrangers and the Banks
                  or any of them or any other person, the amount of such loss
                  being the amount which the person or persons suffering it
                  would otherwise have been entitled to recover from the
                  Borrower.

20.   Preservation of Rights

20.1 The obligations of the Guarantor herein contained shall be in addition to
and independent of every other security which the Agent, the Arrangers and the
Banks or any of them may at any time hold in respect of any of the Borrower's
obligations hereunder.

20.2 The obligations of the Guarantor herein contained shall constitute and be
continuing obligations notwithstanding any settlement of account or other matter
or thing whatsoever, and in particular but without limitation, shall not be
considered satisfied by any intermediate payment or satisfaction of all or any
of the obligations of the Borrower under this Agreement and shall continue in
full force and effect until final payment in full of all amounts owing by the
Borrower hereunder and total satisfaction of all the Borrower's actual and
contingent obligations hereunder.

20.3 Neither the obligations of the Guarantor herein contained nor the rights,
powers and remedies conferred in respect of the Guarantor upon the Agent, the
Arrangers and the Banks or any of them by this Agreement or by law shall be
discharged, impaired or otherwise affected by:


                                       34
<PAGE>

            (i)   the winding-up, dissolution, administration or re-organisation
                  of the Borrower or any other person or any change in its
                  status, function, control or ownership;

            (ii)  any of the obligations of the Borrower or any other person
                  hereunder or under any other security taken in respect of any
                  of its obligations hereunder being or becoming illegal,
                  invalid, unenforceable or ineffective in any respect;

            (iii) time or other indulgence being granted or agreed to be granted
                  to the Borrower in respect of its obligations hereunder or
                  under any such other security;

            (iv)  any amendment to, or any variation, waiver or release of, any
                  obligation of the Borrower hereunder or under any such other
                  security;

            (v)   any failure to take, or fully to take, any security
                  contemplated hereby or otherwise agreed to be taken in respect
                  of the Borrower's obligations hereunder;

            (vi)  any failure to realise or fully to realise the value of, or
                  any release, discharge, exchange or substitution of, any
                  security taken in respect of the Borrower's obligations
                  hereunder; or

            (vii) any other act, event or omission which, but for this Clause
                  20.3, might operate to discharge, impair or otherwise affect
                  any of the obligations of the Guarantor herein contained or
                  any of the rights, powers or remedies conferred upon the
                  Agent, the Arrangers and the Banks or any of them by this
                  Agreement or by law.

20.4 Any settlement or discharge between the Guarantor and the Agent, the
Arrangers and the Banks or any of them shall be conditional upon no security or
payment to the Agent, the Arrangers and the Banks or any of them by the Borrower
or the Guarantor or any other person on behalf of the Borrower or, as the case
may be, the Guarantor being avoided or reduced by virtue of any provisions or
enactments relating to bankruptcy, insolvency, liquidation or similar laws of
general application for the time being in force and, if any such security or
payment is so avoided or reduced, the Agent, the Arrangers and the Banks shall
each be entitled to recover the value or amount of such security or payment from
the Guarantor subsequently as if such settlement or discharge had not occurred.

20.5 Neither the Agent, the Arrangers and the Banks nor any of them shall be
obliged before exercising any of the rights, powers or remedies conferred upon
them in respect of the Guarantor by this Agreement or by law:

            (i)   to make any demand of the Borrower;


                                       35
<PAGE>

            (ii)  to take any action or obtain judgment in any court against the
                  Borrower;

            (iii) to make or file any claim or proof in a winding-up or
                  dissolution of the Borrower; or

            (iv)  to enforce or seek to enforce any other security taken in
                  respect of any of the obligations of the Borrower hereunder.

20.6 The Guarantor agrees that, so long as any amounts are or may be owed by the
Borrower hereunder or the Borrower is under any actual or contingent obligations
hereunder, the Guarantor shall not exercise any rights which the Guarantor may
at any time have by reason of performance by it of its obligations hereunder:

            (i)   to be indemnified by the Borrower; and/or

            (ii)  to claim any contribution from any other guarantor of the
                  Borrower's obligations hereunder; and/or

            (iii) to take the benefit (in whole or in part and whether by way of
                  subrogation or otherwise) of any rights of the Agent, the
                  Arrangers and the Banks hereunder or of any other security
                  taken pursuant to, or in connection with, this Agreement by
                  all or any of the Agent, the Arrangers and the Banks.

                         DEFAULT INTEREST AND INDEMNITY

21.   Default Interest and Indemnity

21.1 If any sum due and payable by either of the Obligors hereunder is not paid
on the due date therefor in accordance with the provisions of Clause 23 or if
any sum due and payable by either of the Obligors under any judgment of any
court in connection herewith is not paid on the date of such judgment, the
period beginning on such due date or, as the case may be, the date of such
judgment and ending on the date upon which the obligation of such Obligor to pay
such sum (the balance thereof for the time being unpaid being herein referred to
as an "unpaid sum") is discharged shall be divided into successive periods, each
of which (other than the first) shall start on the last day of the preceding
such period and the duration of each of which shall (except as otherwise
provided in this Clause 21) be selected by the Agent.

21.2 During each such period relating thereto as is mentioned in Clause 21.1 an
unpaid sum shall bear interest at the rate per annum which is the sum from time
to time of one per cent., the Margin and LIBOR on the Quotation Date therefor
Provided that:

            (i)   if, for any such period, LIBOR cannot be determined, the rate
                  of interest applicable to such unpaid sum shall be the sum
                  from time to 


                                       36
<PAGE>

                  time of one per cent., the Margin and the rate per annum
                  determined by the Agent to be the weighted arithmetic mean
                  (rounded upwards, if not already such a multiple, to the
                  nearest whole multiple of one-sixteenth of one per cent.) of
                  the rates notified by each Bank to the Agent before the last
                  day of such period to be those which express as a percentage
                  rate per annum the cost to it of funding from whatever source
                  it may select its portion of such unpaid sum for such period;
                  and

            (ii)  if such unpaid sum is all or part of an Advance which became
                  due and payable on a day other than the last day of the Term
                  thereof, the first such period applicable thereto shall be of
                  a duration equal to the unexpired portion of that Term and the
                  rate of interest applicable thereto from time to time during
                  such period shall be that which exceeds by one per cent. the
                  rate which would have been applicable to it had it not so
                  fallen due.

21.3 Any interest which shall have accrued under Clause 21.2 in respect of any
unpaid sum shall be due and payable and shall be paid by the Obligor owing such
unpaid sum at the end of the period by reference to which it is calculated or on
such other date or dates as the Agent may specify by written notice to such
Obligor.

21.4 If any Bank or the Agent on its behalf receives or recovers all or any part
of such Bank's share of an Advance otherwise than on the last day of the Term
thereof, the Borrower shall pay to the Agent on demand for account of such Bank
an amount equal to the amount (if any) by which (i) the additional interest
which would have been payable on the amount so received or recovered had it been
received or recovered on the last day of the Term thereof exceeds (ii) the
amount of interest which in the opinion of the Agent would have been payable to
the Agent on the last day of the Term thereof in respect of a deposit in the
currency of the amount so received or recovered equal to the amount so received
or recovered placed by it with a prime bank in London for a period starting on
the third business day following the date of such receipt or recovery and ending
on the last day of the Term thereof.

21.5  The Borrower undertakes to indemnify:

            (i)   each of the Agent, the Arrangers and the Banks against any
                  cost, claim, loss, expense (including legal fees) or liability
                  together with any VAT thereon, which any of them may sustain
                  or incur as a consequence of the occurrence of any Event of
                  Default or any default by the Borrower in the performance of
                  any of the obligations expressed to be assumed by it in this
                  Agreement;

            (ii)  the Agent against any loss it may suffer as a result of its
                  entering into, or performing, any foreign exchange contract
                  for the purposes of Part 10;


                                       37
<PAGE>

            (iii) each Bank against any loss it may suffer as a result of its
                  funding its portion of an Advance requested by the Borrower
                  hereunder but not made by reason of the operation of any one
                  or more of the provisions hereof; and

            (iv)  each Bank against any loss it may suffer as a result of an
                  Advance having been requested in an Optional Currency and such
                  Bank funding its portion of such Advance in such Optional
                  Currency but such Advance being denominated in dollars and
                  being made in dollars by reason of the provisions of Clause
                  6.5(ii).

21.6 Any unpaid sum shall (for the purposes of this Clause 21 and Clause 13.1)
be treated as an advance and accordingly in this Clause 21 the term "Advance"
includes any unpaid sum and "Term", in relation to an unpaid sum, includes each
such period relating thereto as is mentioned in Clause 21.1.

22.   Currency of Account and Payment

22.1 The dollar is the currency of account and payment for each and every sum at
any time due from either the Obligors hereunder Provided that:

            (i)   each repayment of an Advance or a part thereof shall be made
                  in the currency in which such Advance is denominated at the
                  time of that repayment;

            (ii)  each payment of interest shall be made in the currency in
                  which the sum in respect of which such interest is payable is
                  denominated;

            (iii) each payment in respect of costs and expenses shall be made in
                  the currency in which the same were incurred;

            (iv)  each payment pursuant to Clause 11.2 or Clause 13.1 shall be
                  made in the currency specified by the party claiming
                  thereunder; and

            (v)   any amount expressed to be payable in a currency other than
                  dollars shall be paid in that other currency.

22.2 If any sum due from either of the Obligors under this Agreement or any
order or judgment given or made in relation hereto has to be converted from the
currency (the "first currency") in which the same is payable hereunder or under
such order or judgment into another currency (the "second currency") for the
purpose of (i) making or filing a claim or proof against such Obligor, (ii)
obtaining an order or judgment in any court or other tribunal or (iii) enforcing
any order or judgment given or made in relation hereto, the Borrower shall
indemnify and hold harmless each of the persons to whom such sum is due from and
against any loss suffered as a result of any discrepancy between (a) the rate of
exchange used for such purpose to convert the sum in question from the first
currency into the second currency and (b) the rate or rates of exchange at which
such person may in the ordinary course of business purchase the first currency
with the second currency upon receipt of a sum paid to it in satisfaction, in
whole or in part, of any such order, judgment, claim or proof.

23.   Payments

23.1 On each date on which this Agreement requires an amount to be paid by
either of the Obligors or any of the Banks hereunder, such Obligor or, as the
case may be, such Bank shall make the same available to the Agent:

            (i)   where such amount is denominated in dollars, by payment in
                  dollars and in same day funds (or in such other funds as may
                  for the time being be customary in New York City for the
                  settlement in New York

                  Agent's account number 1110021 chips id: 269680 with
                  Skandinaviska Enskilda Banken, New York, N.Y. USA (or such
                  other account or bank as the Agent may have specified for this
                  purpose); or

            (ii)  where such amount is denominated in an Optional Currency, by
                  payment in such Optional Currency and in immediately
                  available, freely transferable, cleared funds to such account
                  with such bank in the principal financial centre of the
                  country of such Optional Currency as the Agent shall have
                  specified for this purpose.

23.2 If, at any time, it shall become impracticable (by reason of any action of
any governmental authority or any change in law, exchange control regulations or
any similar event) for either of the Obligors to make any payments hereunder in
the manner specified in Clause 23.1, then such Obligor may agree with each or
any of the Banks alternative arrangements for the payment direct to such Bank of
amounts due to such Bank hereunder Provided that, in the absence of any such
agreement with any Bank, such Obligor shall be obligated to make all payments
due to such Bank in the manner specified herein. Upon reaching such agreement
such Obligor and such Bank shall immediately notify the Agent thereof and shall
thereafter promptly notify the Agent of all payments made direct to such Bank.

23.3 Save as otherwise provided herein, each payment received by the Agent for
the account of another person pursuant to Clause 23.1 shall:

            (i)   in the case of a payment received for the account of the
                  Borrower, be made available by the Agent to the Borrower by
                  application:

                  (a)   first, in or towards payment (on the date, and in the
                        currency and funds, of receipt) of any amount then due
                        from the Borrower hereunder to the person from whom the
                        amount was so received or in or towards the purchase of
                        any amount of any currency to be so applied; and

                  (b)   secondly, in or towards payment (on the date, and in the
                        currency and funds, of receipt) to such account with
                        such bank in the principal financial centre of the
                        country of the currency of such payment as the Borrower
                        shall have previously notified to the Agent for this
                        purpose; and

            (ii)  in the case of any other payment, be made available by the
                  Agent to the person for whose account such payment was
                  received (in the case of a Bank, for the account of the
                  Facility Office) for value the same day by transfer to such
                  account of such person with such bank in the principal
                  financial centre of the country of the currency of such
                  payment as such person shall have previously notified to the
                  Agent.

<PAGE>

23.4 All payments required to be made by either of the Obligors hereunder shall
be calculated without reference to any set-off or counterclaim and shall be made
free and clear of and without any deduction for or on account of any set-off or
counterclaim.

23.5 All moneys received, recovered or realised by a Bank by virtue of Clause 19
may, in that Bank's discretion, be credited to a suspense or impersonal account
and may be held in such account for so long as such Bank thinks fit pending the
application from time to time (as such Bank may think fit) of such moneys in or
towards the payment and discharge of any amounts owing by either of the Obligors
to such Bank hereunder.

23.6 Where a sum is to be paid hereunder to the Agent for account of another
person, the Agent shall not be obliged to make the same available to that other
person or to enter into or perform any exchange contract in connection therewith
until it has been able to establish to its satisfaction that it has actually
received such sum, but if it does so and it proves to be the case that it had
not actually received such sum, then the person to whom such sum or the proceeds
of such exchange contract was so made available shall on request refund the same
to the Agent together with an amount sufficient to indemnify the Agent against
any cost or loss it may have suffered or incurred by reason of its having paid
out such sum or the proceeds of such exchange contract prior to its having
received such sum.

24.   Set-Off

Each of the Obligors authorises each Bank to apply any credit balance to which
such Obligor is entitled on any account of such Obligor with that Bank in
satisfaction of any sum due and payable from such Obligor to such Bank hereunder
but unpaid; for this purpose, each Bank is authorised to purchase with the
moneys standing to the credit of any such account such other currencies as may
be necessary to effect such application. No Bank shall be obliged to exercise
any right given to it by this Clause 24.

25.   Redistribution of Payments

25.1 If, at any time, the proportion which any Bank (a "Recovering Bank") has
received or recovered (whether by payment, the exercise of a right of set-off or
combination of accounts or otherwise) in respect of its portion of any payment
(a "relevant payment") to be made under this Agreement by either of the Obligors
for account of such Recovering Bank and one or more other Banks is greater (the
portion of such receipt or recovery giving rise to such excess proportion being
herein called an "excess amount") than the proportion thereof so received or
recovered by the Bank or Banks so receiving or recovering the smallest
proportion thereof, then:

            (i)   such Recovering Bank shall pay to the Agent an amount equal to
                  such excess amount;

            (ii)  there shall thereupon fall due from such Obligor to such
                  Recovering Bank an amount equal to the amount paid out by such
                  Recovering Bank pursuant to paragraph (i) above, the amount so
                  due being, for the 


                                       41

                  purposes hereof, treated as if it were an unpaid part of such
                  Recovering Bank's portion of such relevant payment; and

            (iii) the Agent shall treat the amount received by it from such
                  Recovering Bank pursuant to paragraph (i) above as if such
                  amount had been received by it from such Obligor in respect of
                  such relevant payment and shall pay the same to the persons
                  entitled thereto (including such Recovering Bank) pro rata to
                  their respective entitlements thereto,

Provided that to the extent that any excess amount is attributable to a payment
to a Bank pursuant to Clause 23.3(i)(a) such portion of such excess amount as is
so attributable shall not be required to be shared pursuant hereto.

25.2 If any sum (a "relevant sum") received or recovered by a Recovering Bank in
respect of any amount owing to it by either the Obligors becomes repayable and
is repaid by such Recovering Bank, then:

            (i)   each Bank which has received a share of such relevant sum by
                  reason of the implementation of Clause 25.1 shall, upon
                  request of the Agent, pay to the Agent for account of such
                  Recovering Bank an amount equal to its share of such relevant
                  sum together with its share of such amount (if any) as is
                  necessary to reimburse the Recovering Bank for any interest it
                  shall have been obliged to pay to either of the Obligors in
                  respect thereof when repaying such relevant sum to such
                  Obligor; and

            (ii)  there shall thereupon fall due from such Obligor to each such
                  Bank an amount equal to the amount paid out by it pursuant to
                  paragraph (i) above, the amount so due being, for the purposes
                  hereof, treated as if it were the sum payable to such Bank
                  against which such Bank's share of such relevant sum was
                  applied.

25.3 A Bank shall not be obliged to share any amount pursuant to clause 25.1 if
it has received or recovered such amount as a result of taking legal proceedings
with any other Bank which had an opportunity to participate in those legal
proceedings but did not do so and did not separately take equivalent legal
proceedings.

                                AGENCY PROVISIONS

28.   The Agent, the Arrangers and the Banks

28.1 Each Arranger and each Bank hereby appoints the Agent to act as its agent
in connection herewith and authorises the Agent to exercise such rights, powers,
authorities and discretions as are specifically delegated to the Agent by the
terms hereof together with all such rights, powers, authorities and discretions
as are reasonably incidental thereto.

28.2  The Agent may:

      (i)   assume that:

            (a)   any representation made by either of the Obligors in
                  connection herewith is true;

            (b)   no Event of Default or Potential Event of Default has
                  occurred:

            (c)   neither of the Obligors is in breach of or default under its
                  obligations hereunder; and

            (d)   any right, power, authority or discretion vested herein upon
                  an Instructing Group, the Banks or any other person or group
                  of persons has not been exercised,

            unless it has, in its capacity as agent for the Banks, received
            notice to the contrary from any other party hereto or (in case of a
            payment default hereunder) gained actual acknowledge to the
            contrary;

      (ii)  assume that the Facility Office of each Bank is that identified with
            its signature below (or, in the case of a Transferee, at the end of
            the Transfer Certificate to which it is a party as Transferee) until
            it has received from such Bank a notice designating some other
            office of such Bank to replace its Facility Office and act upon any
            such notice until the same is superseded by a further such notice;

      (iii) engage and pay for the advice or services of any lawyers,
            accountants, surveyors or other experts whose advice or services may
            to it seem necessary, expedient or desirable and rely upon any
            advice so obtained;

      (iv)  rely as to any matters of fact which might reasonably be expected to
            be within the knowledge of either of the Obligors upon a certificate
            signed by or on behalf of such Obligor;

      (v)   rely upon any communication or document believed by it to be
            genuine;


                                       44
<PAGE>

      (vi)  refrain from exercising any right, power or discretion vested in it
            as agent hereunder unless and until instructed by an Instructing
            Group as to whether or not such right, power or discretion is to be
            exercised and, if it is to be exercised, as to the manner in which
            it should be exercised;

      (vii) refrain from beginning any legal action or proceeding in connection
            with this Agreement on behalf of any Bank until such Bank has given
            its written consent thereto;

     (viii) refrain from acting in accordance with any instructions of an
            Instructing Group to begin any legal action or proceeding arising
            out of or in connection with this Agreement until it shall have
            received such security as it may require (whether by way of payment
            in advance or otherwise) for all costs, claims, losses, expenses
            (including legal fees) and liabilities together with any VAT thereon
            which it will or may expend or incur in complying with such
            instructions; and

      (ix)  if it is unable to obtain instructions or communicate with a Bank
            after making reasonable attempts to do so, either refrain from
            acting as Agent on behalf of such Bank or take such action on behalf
            of such Bank as it in its absolute discretion deems appropriate and
            reasonable and shall not be liable to such Bank as a result of any
            such action or inaction.

28.3  The Agent shall:

      (i)   promptly inform each Bank of the contents of any notice or document
            received by it in its capacity as Agent from either of the Obligors
            hereunder;

      (ii)  promptly notify each Bank of the occurrence of any Event of Default
            or any default by either of the Obligors in the due performance of
            or compliance with its obligations under this Agreement of which the
            Agent, in its capacity as agent for the Banks, has received express
            notice from any other party hereto or (in the case of a payment
            default hereunder) gained actual knowledge,

      (iii) save as otherwise provided herein, act as agent hereunder in
            accordance with any instructions given to it by an Instructing
            Group, which instructions shall be binding on all of the Arrangers
            and the Banks; and

      (iv)  if so instructed by an Instructing Group, refrain exercising any
            right, power or discretion vested in it as agent hereunder.

28.4 Notwithstanding anything to the contrary expressed or implied herein.
neither the Agent nor any of the Arrangers shall:

      (i)   be bound to enquire as to:

            (a)   whether or not any representation made by either of the
                  Obligors in connection herewith is true;


                                       45
<PAGE>

            (b)   the occurrence or otherwise of any Event of Default or
                  Potential Event of Default;

            (c)   the performance by either of the Obligors of its obligations
                  hereunder; or

            (d)   any breach of or default by either of the Obligors of or under
                  its obligations hereunder;

      (ii)  be bound to account to any Bank for any sum or the profit element of
            any sum received by it for its own account;

      (iii) be bound to disclose to any other person any information relating to
            any member of the Group if such disclosure would or might in its
            opinion constitute a breach of any law or regulation or be otherwise
            actionable at the suit of any person; or

      (iv)  be under any obligations other than those for which express
            provision is made herein.

28.5 Each Bank shall, in its Proportion, from time to time on demand by the
Agent, indemnify the Agent (to the extent the Agent has not previously been
indemnified by the Borrower), against any and all costs, claims, losses,
expenses (including legal fees) and liabilities together with any VAT thereon
which the Agent may incur, otherwise than by reason of its own gross negligence
or wilful misconduct, in acting in its capacity as agent hereunder.

28.6 Neither the Agent and the Arrangers nor any of them accepts any
responsibility for the accuracy and/or completeness of the Information
Memorandum or any other information supplied by either of the Obligors in
connection herewith or for the legality, validity, effectiveness, adequacy or
enforceability of this Agreement and neither the Agent and the Arrangers nor any
of them shall be under any liability as a result of taking or omitting to take
any action in relation to this Agreement, save in the case of gross negligence
or wilful misconduct.

28.7 Each of the Banks agrees that it will not assert or seek to assert against
any director, officer or employee of the Agent or any Arranger any claim it
might have against any of them in respect of the matters referred to in Clause
28.6.

28.8 The Agent and each of the Arrangers may accept deposits from, lend money to
and generally engage in any kind of banking or other business with any member of
the Group.

28.9 The Agent may resign its appointment thereunder at any time without
assigning any reason therefor by giving not less than thirty days' prior written
notice to that effect to each of the other parties hereto or an Instructing
Group may at any time terminate the appointment of the Agent by giving not less
than sixty days' prior written notice to the Agent, copied to all parties
hereto. Provided that no such resignation or termination shall be 


                                       46
<PAGE>

effective until a successor for the Agent is appointed in accordance with the
succeeding provisions of this Clause 28.

28.10 If the Agent gives notice of its resignation, or its appointment is
terminated, pursuant to Clause 28.9, then any reputable and experienced bank or
other financial institution may be appointed as a successor to the Agent by an
Instructing Group during the period of such notice but, if no such successor is
so appointed, the Agent may appoint such a successor itself which shall be a
reputable and experienced bank or other financial institution.

28.11 If a successor to the Agent is appointed under the provisions of Clause
28.10, then (i) the retiring Agent shall be discharged from any further
obligation hereunder but shall remain entitled to the benefit of the provisions
of this Clause 28 and (ii) its successor and each of the other parties hereto
shall have the same rights and obligations amongst themselves as they would have
had if such successor had been a party hereto.

28.12 It is understood and agreed by each Bank that it has itself been, and will
continue to be, solely responsible for making its own independent appraisal of
and investigations into the financial condition, creditworthiness, condition,
affairs, status and nature of each member of the Group and, accordingly, each
Bank warrants to the Agent and the Arrangers that it has not relied on and will
not hereafter rely on the Agent and the Arrangers nor any of them:

            (i)   to check or enquire on its behalf into the adequacy, accuracy
                  or completeness of any information provided by either of the
                  Obligors in connection with this Agreement or the transactions
                  herein contemplated (whether or not such information has been
                  or is hereafter circulated to such Bank by the Agent and the
                  Arrangers or any of them); or

            (ii)  to assess or keep under review on its behalf the financial
                  condition, creditworthiness, condition, affairs, status or
                  nature of any member of the Group.

28.13 In acting as Agent for the Banks, the Agent's agency division shall be
treated as a separate entity from any other of its divisions or departments and,
notwithstanding the foregoing provisions of this Clause 28, in the event that
the Agent should act for any member of the Group in any capacity in relation to
any other matter, any information given by such member of the Group to the Agent
in such other capacity may be treated as confidential by the Agent.

                            ASSIGNMENTS AND TRANSFERS

29.   Benefit of Agreement

This Agreement shall be binding upon and enure to the benefit of each party
hereto and its or any subsequent successors, Transferees and assigns.

30.   Assignments and Transfers by the Obligors

Neither of the Obligors shall be entitled to assign or transfer all or any of
its rights, benefits and obligations hereunder.

31.   Assignments and Transfers by Banks

31.1 Any Bank may, at any time, assign all or any of its rights and benefits
hereunder or transfer in accordance with Clause 31.3 all or any of its rights,
benefits and obligations hereunder Provided that (i) no such assignment or
transfer (other than (i) to an affiliate of such Bank having its Facility Office
in a country in which another Bank has its Facility Office or (ii) to a Bank)
may be made without the prior written consent of the Borrower, such consent not
to be unreasonably withheld or delayed and to be deemed to have been given if a
response to a request for such consent is not received from the Borrower by such
Bank within fifteen business days of such request (incorporating such fifteen
business days deadline) being made, and (ii) no such transfer or assignment may
be made if the result thereof, at the time of such transfer or assignment or
immediately thereafter would be that either Obligor would be liable to pay an
additional amount or amounts pursuant to Clauses 11.1 or 13.1 which additional
amount or amounts would not have been payable had no such transfer or assignment
occurred unless the transferee or assignee accept responsibility to reimburse
such Obligor for any additional amount or amounts.

31.2 If any Bank assigns all or any of its rights and benefits hereunder in
accordance with Clause 31.1, then, unless and until the assignee has agreed with
the Agent, the Arrangers and the other Banks that it shall be under the same
obligations towards each of them as it would have been under if it had been an
original party hereto as a Bank, the Agent, the Arrangers and the other Banks
shall not be obliged to recognise such assignee as having the rights against
each of them which it would have had if it had been such a party hereto.

31.3 If any Bank wishes to transfer all or any of its rights, benefits and/or
obligations hereunder as contemplated in Clause 31.1, then such transfer may be
effected by the delivery to the Agent of a duly completed and duly executed
Transfer Certificate in which event, on the later of the Transfer Date specified
in such Transfer Certificate and the fifth business day after (or such earlier
business day endorsed by the Agent on such Transfer Certificate falling on or
after) the date of delivery of such Transfer Certificate to the Agent:


                                       48
<PAGE>

            (i)   to the extent that in such Transfer Certificate the Bank party
                  thereto seeks to transfer its rights, benefits and obligations
                  hereunder, each of the Obligors and such Bank shall be
                  released from further obligations towards one another
                  hereunder and their respective rights against one another
                  shall be cancelled (such rights, benefits and obligations
                  being referred to in this Clause 31.3 as "discharged rights
                  and obligations");

            (ii)  each of the Obligors and the Transferee party thereto shall
                  assume obligations towards one another and/or acquire rights
                  against one another which differ from such discharged rights
                  and obligations only insofar as such Obligor and such
                  Transferee have assumed and/or acquired the same in place of
                  such Obligor and such Bank; and

            (iii) the Agent, the Arrangers, such Transferee and the other Banks
                  shall acquire the same rights and benefits and assume the same
                  obligations between themselves as they would have acquired and
                  assumed had such Transferee been an original party hereto as a
                  Bank with the rights, benefits and/or obligations acquired or
                  assumed by it as a result of such transfer.

31.4 On the date upon which a transfer takes effect pursuant to Clause 31.3, the
Transferee in respect of such transfer shall pay to the Agent for its own
account a transfer fee of $800, payable under pre-advice, and notwithstanding
the provisions of Clause 31.3 such transfer shall not be effective until such
transfer fee is received by the Agent.

32.   Disclosure of Information

Any Bank may disclose to any actual or potential assignee or Transferee or to
any person who may otherwise enter into contractual relations with such Bank in
relation to this Agreement such information about this Agreement or the Obligors
and the Group as such Bank shall consider appropriate.

hereunder is to be increased under Clause 11.1 or (ii) the amount for the time

34.   Remedies and Waivers

No failure to exercise, nor any delay in exercising, on the part of the Agent,
the Arrangers and the Banks or any of them, any right or remedy hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right or remedy prevent any further or other exercise thereof or the exercise of
any other right or remedy. The rights and remedies herein provided are
cumulative and not exclusive of any rights or remedies provided by law.

35.   Partial Invalidity

If, at any time, any provision hereof is or becomes illegal, invalid or
unenforceable in any respect under the law of any jurisdiction. neither the

                              LAW AND JURISDICTION

37. Law

This Agreement shall be governed by, and shall be construed in accordance with,
English law.

38.   Jurisdiction

38.1 Each of the parties hereto irrevocably agrees for the benefit of each of
the Agent, the Arrangers and the Banks that the courts of England shall have
jurisdiction to hear and determine any suit, action or proceeding, and to settle
any disputes, which may arise out of or in connection with this Agreement and,
for such purposes, irrevocably submits to the jurisdiction of such courts.

38.2 Each of the Obligors irrevocably waives any objection which it might now or
hereafter have to the courts referred to in Clauses 38.1 being nominated as the
forum to hear and determine any suit, action or proceeding, and to settle any
disputes, which may arise out of or in connection with this Agreement and agrees
not to claim that any such court is not a convenient or appropriate forum.

38.3 Each of the Obligors agrees that the process by which any suit, action or
proceeding is begun may be served on it by being delivered in England, to
Incentive Group Limited, c/o Munters Ltd, Blackstone Road, Huntingdon, Cambs
PE18 6EP, England or other its principal place of business for the time being.
If the appointment of the person mentioned in this Clause 38.3 ceases to be
effective in respect of either or both Obligors, such Obligor or Obligors shall
immediately appoint a further person in England to accept service of process on
its behalf in England and, failing such appointment within 15 days, the Agent
shall be entitled to appoint such a person by notice to such Obligor or
Obligors. Nothing contained herein shall affect the right to serve process in
any other manner permitted by law.

38.4 The submission to the jurisdiction of the courts referred to in Clauses
38.1 shall not (and shall not be construed so as to) limit the right of the
Agent, the Arrangers and the Banks or any of them to take proceedings against
either of the Obligors in any other court of competent jurisdiction nor shall
the taking of proceedings in any one or more jurisdictions preclude the taking
of proceedings in any other jurisdiction (whether concurrently or not) if and to
the extent permitted by applicable law.

38.5 Each of the Obligors hereby consents generally in respect of any legal
action or proceeding arising out of or in connection with this Agreement to the
giving of any relief or the issue of any process in connection with such action
or proceeding including, without limitation, the making. enforcement or
execution against any property whatsoever (irrespective of its use or intended
use) of any order or judgment which may be made or given in such action or
proceeding.


                                       52
<PAGE>

38.6 To the extent that either of the Obligors may in any jurisdiction claim for
itself or its assets immunity from suit, execution, attachment (whether in aid
of execution, before judgment or otherwise) or other legal process and to the
extent that in any such jurisdiction there may be attributed to itself or its
assets such immunity (whether or not claimed), such Obligor hereby irrevocably
agrees not to claim and hereby irrevocably waives such immunity to the full
extent by the laws of such jurisdiction.

AS WITNESS the hands of the duly authorised representatives of the parties
hereto the day and year first before written.

                              for and on behalf of
                          Incentive Treasury AB (publ)

                               THE FIFTH SCHEDULE

            Opinion of the Borrower's and Guarantor's Swedish Counsel

To:   Enskilda, Skandinaviska Enskilda Banken AB (publ) as agent on its own
      behalf and for and on behalf of the Arrangers and the Banks referred to in
      the Facility Agreement mentioned below.

Dear Sirs,

1. We have acted on behalf of Incentive Treasury AB (publ) and Incentive AB
(publ) in connection with an agreement (the "Facility Agreement") dated 4 March,
1996 and made between Incentive Treasury AB (publ) as borrower, Incentive AB
(publ) as guarantor, Deutsche Bank Luxembourg S.A. and Enskilda, Skandinaviska
Enskilda Banken AB (publ) as arrangers, Enskilda, Skandinaviska Enskilda Banken
AB (publ) as agent and the financial institutions defined therein as Banks.

2. Terms defined in the Facility Agreement shall have the same meaning herein.

3. We have examined a signed copy of the Facility Agreement and such other
documents as we have considered it necessary or desirable to examine and, on the
assumption that the Facility Agreement is valid and legally binding under
English law (and subject as mentioned below), we are of the opinion that

      (A)   the statements set out in Clause 15.1 (i) - (x) of the Facility
            Agreement are true insofar as the same relate to the Obligors; and

      (B)   a judgement obtained in a court in England is enforceable in Sweden
            pursuant to the rules of the 1988 Lugano Convention on Jurisdiction
            and the Enforcement of Judgements in Civil Matters (the "Lugano
            Convention") as implemented in Sweden. If such judgment does not
            satisfy the applicable enforcement provisions of the Lugano
            Convention then, we believe, although there is no legislative
            authority on the subject, that in view of the judicial developments
            in Sweden that Swedish courts would give an enforceable Swedish
            judgment on the basis of a judgment for money obtained in an English
            court provided that such English judgment was given by a competent
            court in England, had gained legal force according to the applicable
            procedural rules in England and is not contrary to public policy in
            Sweden.

4. This opinion is confined to matters of Swedish law and no opinion is
expressed as to the laws of any other jurisdiction.

5. We have assumed the following:


                                       62
<PAGE>

1.    The Facility Agreement is within the capacity and power of and has been
      validly authorized, executed and delivered by and is binding on the
      parties thereto, other than the Obligors, which matters we have not
      independently verified; and

2.    The genuineness of all signatures and the authenticity of all documents
      submitted to us as originals and the conformity with the originals of all
      documents submitted to us as copies thereof, and we have found nothing to
      indicate that such assumptions are not fully justified.

The qualifications to which this opinion is subject are as follows:

1.    The availability in Swedish courts of equitable remedies, such as
      injunction and specific performance, is restricted under Swedish law.

2.    Swedish courts may award judgments expressed in foreign currencies, but an
      enforcement in Sweden by the execution authorities of a payment order in
      the judgment can generally only be performed in Swedish Kronor.
      Enforcement in Sweden of such judgments would, if implemented in Swedish
      Kronor, be generally at the rate of exchange prevailing at the date of
      enforcement rather than at the date of judgment.

3.    Nothing in this opinion must be taken as indicating that obligations would
      be specifically enforceable and an enforcement of any agreement or
      instrument may be limited by bankruptcy, insolvency, liquidation,
      reorganisation, limitation, and other laws of general application
      regarding or affecting the rights or creditors.

4.    Pursuant to the Swedish Contract Act, a contract term may be modified or
      set aside if it is adjudged to be unreasonable. Where any party to an
      agreement is vested with a discretion or may determine a matter in its
      opinion, Swedish law may require that such discretion is exercised
      reasonably or that such opinion is based on reasonable grounds and a
      provision that a certain determination is conclusive and binding will not
      prevent judicial enquiry into the merits of any claim by an aggrieved
      party.

5.    A Swedish court may reject the right to take proceedings in Sweden if
      proceedings which may have or may lead to a judgment which is enforceable
      in Sweden have already been taken in another court of competent
      jurisdiction within or outside Sweden.

6.    In giving the foregoing opinion, we have relied as to certain factual
      matters upon certificates of officers of the Obligors and of public
      officials.

7.    This opinion is confirmed to and is given on the basis of Swedish law as
      it exists at the date hereof. We have made no investigations of the laws
      of England as a basis for this opinion and do not express or imply any
      opinion thereon.


                                       63
<PAGE>

8.    This opinion is strictly limited to the matters stated herein and is not
      to be read as extending by implication to any other matters in connection
      with the Facility Agreement referred to herein or the transactions
      contemplated by such agreement.

This opinion is addressed to you and, without our express consent, is not to be
transmitted to any other person, nor is it to be relied upon by any other person
or for any purpose.

Yours faithfully,
ADVOKATFIRMAN VINGE

      as Borrower and guaranteed by Incentive AB (publ) as Guarantor

1. We have acted as your legal advisers in Sweden in connection with the

<PAGE>

      (f)   a copy of a board resolution of the Guarantor passed at a meeting of
            its board of directors held on [__________] approving the giving of
            its guarantee under the Facility Agreement;

      (g)   a copy of the power of attorney dated [______], 1996 authorizing Mr.
            [____________] and Mr. [_____________] jointly to sign the Facility
            Agreement on behalf of the Borrower; and

      (h)   a copy of the power of attorney dated [__________], 1996 authorizing
            Mr. [______] and Mr. [__________] jointly to sign the Facility
            Agreement on behalf of the Guarantor.

3. We have assumed the following:

      (A)   the Facility Agreement is within the capacity and power of and has
            been validly authorized, executed and delivered by and is binding on
            the parties thereto, other than the Borrower and the Guarantor,
            which matters we have nor independently verified;

      (B)   the Facility Agreement and the rights and obligations created
            thereby are valid and legally binding under the laws of England, by
            which they are expressed to be governed; and

      (C)   the genuineness of all signatures and the authenticity of all
            documents submitted to us as originals and the conformity with the
            originals of all documents submitted to us as copies thereof;

and we have found nothing to indicate that such assumptions are not fully
justified.

Terms defined in the Facility Agreement shall, when used in this opinion, have
the same meanings herein as therein unless otherwise defined.

4. Based on the foregoing, we are of the opinion that:

      (A)   so far as the laws of Sweden are concerned that the statements set
            out in Clause 15.1 of the Facility Agreement are true and correct as
            far as they relate to each Obligor respectively; and

      (B)   a judgement obtained in a court in England is enforceable in Sweden
            pursuant to the rules of the 1988 Lugano Convention on Jurisdiction
            and the Enforcement of Judgments in Civil Matters (the "Lugano
            Convention") as implemented in Sweden. If such judgment does not
            satisfy the applicable enforcement provisions of the Lugano
            Convention then, we believe, although there is no legislative
            authority on the subject, that in view of the judicial developments
            in Sweden that Swedish courts would give an enforceable Swedish
            judgment on the basis of a judgment for money obtained in an English
            court provided that such English judgment was given by a competent
            court in 


                                       66
<PAGE>

            England, had gained legal force according to the applicable
            procedural rules in England and is not contrary to public policy in
            Sweden.

5. The qualifications to which this opinion is subject are as follows:

      (1)   The availability in Swedish courts of equitable remedies, such as
            injunction and specific performance, is restricted under Swedish
            law.

      (2)   Swedish courts may award judgments expressed in foreign currencies
            (including $), but an enforcement in Sweden by the execution
            authorities of a payment order in the judgment can generally only be
            performed in Swedish kronor ("SEK"). Enforcement in Sweden of such
            judgments would, if implemented in SEK, be generally at the rate of
            exchange ruling at the date of enforcement rather than at the date
            of judgment.

      (3)   Nothing in this opinion must be taken as indicating that obligations
            would be specifically enforceable and an enforcement of any
            agreement or instrument may be limited by bankruptcy, insolvency,
            liquidation, reorganisation, limitation, and other laws of general
            application regarding or affecting the rights of creditors.

      (4)   Pursuant to the Swedish Contract Act, a contract term may be
            modified or set aside if it is adjudged to be unreasonable. Where
            any party to an agreement is vested with a discretion or may
            determine a matter in its opinion, Swedish law may require that such
            discretion is exercised reasonably or that such opinion is based on
            reasonable grounds and a provision that a certain determination is
            conclusive and binding will not prevent judicial enquiry into the
            merits of any claim by an aggrieved party. Although the Facility
            Agreement is subject to English law, we cannot express any opinion
            whether a Swedish court would find such equitable rules of the
            Swedish Contracts Act applicable either directly or by reason of
            Swedish public policy. However, in our opinion, having regard to all
            the relevant circumstances, even if such rules of the Swedish
            Contracts Act did apply, neither the Facility Agreement nor the
            terms thereof would be subject to modification or being set aside
            pursuant to such rules.

      (5)   A Swedish court may reject the right to take proceedings in Sweden
            if proceedings which have or may lead to a judgment which is
            enforceable in Sweden have already been taken in another court of
            competent jurisdiction within or outside Sweden.

      (6)   In giving the foregoing opinion, we have relied as to certain
            factual matters upon certificates by officers of the Borrower, the
            Guarantor and by public officials.

      (7)   This opinion is confined to and is given on the basis of Swedish law
            as it exists at the date hereof. We have made no investigations of
            the laws of 


                                       67
<PAGE>

            England as a basis for this opinion and do not express or imply any
            opinion thereon.

      (8)   This opinion is strictly limited to the matters stated herein and is
            not to be read as extending by implication to any other matters in
            connection with the Facility Agreement.

This opinion is addressed to you and, without our express consent, is not to be
transmitted to any other person, nor is it to be relied upon by any other person
(in each case other than your legal advisers) or for any purpose other than in
connection with the Facility Agreement.

                                    Yours faithfully
                                    Hellstrom & Partners

                                     Part 2

                                  THE FACILITY

            2. The Facility

            The Banks grant to the Borrower, upon the terms and subject to the
conditions hereof, a multicurrency revolving credit facility in an aggregate
amount of $500,000,000 or its equivalent from time to time in Optional
Currencies.

            3. Purpose

            3.1 The Facility is intended for general corporate purposes and,
accordingly the Borrower shall apply all amounts raised by it hereunder in or
towards satisfaction thereof Provided that the proceeds of the first Advance
hereunder shall be applied towards repayment of the December 1994 Advance.

            3.2 Neither the Agent, the Arrangers and the Banks nor any of them
shall be obliged to concern themselves with the application of amounts raised
hereunder

            4. Conditions Precedent

            Save as the Banks may otherwise agree, the Borrower may not deliver
any Notice of Drawdown hereunder unless the Agent has confirmed to the Borrower
and the Banks that

            (i) it has received all of the documents listed in the Third
      Schedule and that each is, in form and substance, satisfactory to the
      Agent; and

            (ii) all amounts (with the exception of the December 1994 Advance)
      outstanding under the 1994 Facility have been repaid in full and the
      Borrower and Guarantor (as defined therein) have satisfied all their
      respective obligations thereunder (with the exception of those under the
      December 1994 Advance) and the Agent is satisfied that the Total
      Commitments (as defined therein) of the Banks have been cancelled and
      reduced to zero.

            5. Nature of Banks' Obligations

            5.1 The obligations of each Bank hereunder are several.

            5.2 The failure by a Bank to perform its obligations hereunder shall
not affect the obligations of the Borrower or the Guarantor towards any other
party hereto nor shall any other party be liable for the failure by such Bank to
perform its obligations hereunder.

            5.3 The amounts outstanding at any time hereunder from the Borrower
to any of the other parties hereto shall be a separate and independent debt, and
each such party shall be entitled, subject to having given prior notice thereof
to the Agent, to protect and enforce its individual rights arising out of this
Agreement independently of any other party, and it shall not be necessary for
any party hereto to be joined as an additional party in any proceedings for such
purposes.

                                     Part 3

                           UTILISATION OF THE FACILITY

            6. Utilisation of the Facility

            6.1 Save as otherwise provided herein, the Borrower may from time to
time request the making of an Advance under the Facility by the delivery to the
Agent, not more than ten nor less than four business days before the proposed
date for the making of such Advance, of a duly completed Notice of Drawdown
therefor.

            6.2 Each Notice of Drawdown delivered to the Agent pursuant to
Clause 6.1 shall be irrevocable and shall specify:

            (i) the proposed date for the making of the Advance requested, which
      shall be a business day falling one month or more before the Final
      Maturity Date and which shall be at least five business days after the
      date upon which the previous Advance (if any) was made hereunder;

            (ii) the currency of denomination of the Advance requested, which
      shall be dollars or an Optional Currency Provided that, if the Borrower
      selects an Optional Currency, the Borrower may also select dollars to
      apply if its first selection becomes ineffective pursuant to Clause 6.5;

            (iii) the amount of the Advance requested, which shall be a minimum
      Dollar Amount of $50,000,000 and integral multiple of $10,000,000 or an
      amount equal to the Available Facility and the Dollar Amount of which
      shall not exceed the Available Facility adjusted to take account of:

                  (a) any reduction in the Commitment of a Bank scheduled to be
            made prior to the commencement of the Term in respect of the
            proposed Advance; and

                  (b) the Dollar Amounts of any Advances which are scheduled to
            be made or repaid on or before the date of drawdown of the proposed
            Advance;

            (iv) the proposed Term of the Advance requested, which shall be a
      period of one, three or six months ending on or before the Final Maturity
      Date; and

            (v) the account to which the proceeds of the proposed drawdown are
      to be paid.

            6.3 The Agent shall, promptly after receipt by it of a Notice of
Drawdown, notify the Banks of its receipt of such Notice of Drawdown specifying:

            (i) the proposed date of drawdown;
<PAGE>
                                       11


            (ii) the Dollar Amount, the currency and the Term of the proposed
      Advance; and

            (iii) the participation of the relevant Bank in such Advance.

            6.4 The Borrower may not request more than six (6) Advances to be
outstanding at any time and may not request more than one Advance to be made on
any one day and may not deliver any Notice of Drawdown between the date of any
other Notice of Drawdown made hereunder and the proposed date of drawdown
relating to such other Notice of Drawdown.

            6.5 If the Borrower requests that an Advance be denominated in an
Optional Currency and:

            (i) no later than 12.00 noon on the third business day preceding the
      first day of the Term of such Advance, any Bank notifies the Agent that it
      does not agree to such request; or

            (ii) no later than 11.00 a.m. on the Quotation Date for such
      Advance, the Agent notices the Borrower and the Banks that the Agent is of
      the opinion that it is not feasible for such Advance to be made in such
      Optional Currency; or

            (iii) to give effect to such request would cause the Loan to be
      denominated in more than four (4) Optional Currencies,

then, unless the Borrower and the Banks otherwise agree, such Advance shall not
be made unless the Borrower specified in the Notice of Drawdown in respect of
such Advance that in such event such Advance should be denominated in dollars in
which case such Advance shall be made in dollars in an amount equal to the
Dollar Amount relating to such Notice of Drawdown.

            6.6 If the Borrower requests an Advance in accordance with the
preceding provisions of this Clause 6 and, on the proposed date for the making
of such Advance:

            (i) neither of the events mentioned in Clauses 8(i) and 8(ii) shall
      have occurred;

            (ii) the Dollar Amount of such Advance does not exceed the Available
      Facility; and

            (iii) either:

                  (a) no Event of Default or Potential Event of Default has
            occurred; and

                  (b) the representations set out in Clause 15 (except
            sub-Clauses 15.2(v) and (viii)) are true on and as of the proposed
            date for the making of such Advance

      or each of the Banks agrees (notwithstanding any matter mentioned at (a)
      or (b) above) to participate in the making of such Advance,
<PAGE>
                                       12


then, save as otherwise provided herein, such Advance will be made in accordance
with the provisions hereof either in dollars in an amount equal to the Dollar
Amount requested or, if such Advance is to be denominated in an Optional
Currency, in an amount which is the equivalent in such Optional Currency of the
Dollar Amount requested, calculated as at the business day prior to the
Quotation Date for such Advance (such equivalent amount to be notified by the
Agent to the Banks promptly after its determination).

            6.7 Each Bank will participate through its Facility Office in each
Advance made pursuant to this Clause 6 in the proportion borne by its Available
Commitment to the Available Facility immediately prior to the making of that
Advance.

            6.8 If a Bank's Commitment is reduced in accordance with the terms
hereof after the Agent has received the Notice of Drawdown for an Advance and
such reduction was not taken into account pursuant to Clause 6.2(iii)(a), then
both the Dollar Amount and the actual amount of that Advance shall be reduced
accordingly.

                                     Part 4

                                    INTEREST

            7. Interest

            7.1 On the Repayment Date relating to each Advance the Borrower
shall pay accrued interest on that Advance.

            7.2 The rate of interest applicable to an Advance from time to time
during its Term shall be the rate per annum which is the sum of the Margin (and,
in the case of sterling, the Associated Costs Rate in respect thereof at such
time) and LIBOR applicable to such Advance on the Quotation Date therefor.

            8. Market Disruption and Alternative Interest Rates

            If, in relation to any Advance:

            (i) the Agent determines that at or about 11.00 a.m. on the
      Quotation Date for the Term in respect of such Advance no rates are quoted
      on page 3740 or, as applicable, page 3750 of the Telerate screen for the
      relevant currency (or such other page as may replace such page) and none
      or only one of the Reference Banks was offering to prime banks in the
      London Interbank Market deposits in dollars for the proposed duration of
      such Term; or

            (ii) before the close of business in Luxembourg on the Quotation
      Date for such Term the Agent has been noticed by a Bank or each of a group
      of Banks to whom in aggregate thirty-five per cent. or more of the Dollar
      Amount of the Loan is (or, if an Advance were then made, would be) owed
      that LIBOR as determined by the Agent does not accurately reflect the cost
      to it of obtaining such deposits,

then, notwithstanding the provisions of Clause 7:

            (a) the Agent shall notify the other parties hereto of such event;

            (b) such Advance shall not be made; and

            (c) if the Agent or the Borrower so requires, within five days of
      such notification the Agent and the Borrower shall enter into negotiations
      with a view to agreeing a substitute basis for determining the rates of
      interest which may be applicable to Advances in the future and any such
      substitute basis that is agreed shall take effect in accordance with its
      terms and be binding on each party hereto Provided that the Agent may not
      agree any such substitute basis without the prior consent of each Bank.

                                     Part 5

                           REPAYMENT AND CANCELLATION

            9. Repayment

            9.1 The Borrower shall repay each Advance made to it in full on the
Repayment Date relating thereto.

            9.2 The Borrower shall not repay all or any part of any Advance
outstanding hereunder, except, at the times and in the manner expressly provided
herein but, subject to the terms and conditions hereof, shall be entitled to
reborrow any amount repaid.

            10. Cancellation

            10.1 The Borrower may, by giving to the Agent not less than thirty
(30) days' prior notice to that effect, cancel the whole or any part (being a
minimum amount of $50,000,000 and integral multiple of $10,000,000 or an amount
equal to the Available Facility) of the Total Commitments. Any such cancellation
shall reduce the Commitment of each Bank rateably.

            10.2 Any notice of cancellation given by the Borrower pursuant to
Clause 10.1 shall be irrevocable and shall specify the date upon which such
cancellation is to be made and the amount of such cancellation.

            10.3 If any Bank claims indemnification from the Borrower under
Clause 11.2 or Clause 13.1, the Borrower may, within thirty days thereafter and
by not less than fifteen days' prior notice to the Agent (which notice shall be
irrevocable), cancel such Bank's Commitment whereupon such Bank shall cease to
be obliged to participate in further Advances and its Commitment shall be
reduced to zero.

            10.4 The Borrower and a Bank or Banks may, by giving to the Agent
not less than thirty (30) days' notice to that effect, notify the Agent
(whereupon the Agent shall notify the other Banks) that such Bank or Banks has
or have entered into a LC Agreement with the Borrower by which such Bank or
Banks has or have agreed to issue a Letter of Credit on terms agreed between the
Borrower and such Bank or Banks and irrevocably request the Agent to reduce and
cancel such Bank's or Banks' Commitment by an amount equal to (its portion of)
the Dollar Amount of such Letter of Credit (the amount of each Bank's
participation in a Letter of Credit and the corresponding reduction and
cancellation of such Bank's Commitment to be rounded downwards to the nearest
$10,000,000). The Agent shall reduce and cancel the Commitment of such Bank by
such portion upon and subject to the following conditions:

            (i) the proposed date of expiry of such Letter of Credit shall,
      unless otherwise agreed by the Agent, be a day falling at least 24 months
      after the issuance of such Letter of Credit;

            (ii) the purpose of issuing such Letter of Credit is to secure
      financial indebtedness for borrowed money (not otherwise secured) of
      either Obligor;
<PAGE>
                                       15


            (iii) the proposed Dollar Amount of such Letter of Credit shall be a
      minimum amount of $10,000,000 or integral multiple thereof, and

            (iv) the aggregate Dollar Amount of Letters of Credit issued under
      LC Agreements shall not exceed $150,000,000.

Provided that upon the date of expiry of such Letter of Credit which falls on a
date before the Final Maturity Date, such Bank's Commitment shall be reinstated
by an amount equal to (its portion of) the Dollar Amount of such Letter of
Credit, as adjusted to take account of any intervening cancellations of part of
the Total Commitments, and further provided that the Total Commitments have not
been cancelled pursuant to Clause 18

                                     Part 6

                            CHANGES IN CIRCUMSTANCES

            11. Taxes

            11.1 All payments to be made by either of the Obligors to any person
hereunder shall be made free and clear of and without deduction for or on
account of any applicable tax unless such Obligor is required to make such a
payment subject to the deduction or withholding of tax, in which case the sum
payable by such Obligor in respect of which such deduction or withholding is
required to be made shall be increased to the extent necessary to ensure that,
after the making of the required deduction or withholding, such person receives
and retains (free from any liability in respect of any such deduction or
withholding) a net sum equal to the sum which it would have received and so
retained had no such deduction or withholding been made or required to be made.

            11.2 Without prejudice to the provisions of Clause 11.1, if any
person or the Agent on its behalf is required to make any payment on account of
any applicable tax (not being a tax imposed on the net income of its Facility
Office by the jurisdiction in which it is incorporated or in which its Facility
Office is located) or otherwise on or in relation to any sum received or
receivable hereunder by such person or the Agent on its behalf (including,
without limitation any sum received or receivable under this Clause 11) or any
liability in respect of any such payment is asserted, imposed, levied or
assessed against such person or the Agent on its behalf, the Borrower shall,
upon demand of the Agent, promptly indemnify such person against such payment or
liability, together with any interest, penalties and expenses payable or
incurred in connection therewith.

            11.3 A Bank intending to make a claim pursuant to Clause 11.2 shall
notify the Agent of the event by reason of which it is entitled to do so,
whereupon the Agent shall notify the Borrower thereof Provided that nothing
herein shall require such Bank to disclose any confidential information relating
co the organisation of its affairs.

            11.4 If a Bank receives the benefit of a tax credit or an allowance
resulting from a payment which includes an additional amount paid by an Obligor
under Clause 11.1 or if it is otherwise left in a position which is more
favourable to it than would be the case if such withholding or deduction and
resultant additional payment by the Obligor had not been made, it shall (to the
extent that it can do so without prejudice to the retention of such credit or
allowance and to the extent that it is not unlawful or contrary to any official
directive for it so to do) pay to the relevant Obligor such part of that benefit
as is, in the sole opinion of that Bank, attributable to the withholding or
deduction giving rise to the payment of that additional amount, provided that
such Bank shall:-

            (a) be the sole judge of the amount of any such benefit to be so
      paid to the relevant Obligor and of the date on which it is received;

            (b) have an absolute discretion as to the order and manner in which
      it employs or claims tax credits and allowances available to it as to
      arrange its tax affairs; and

            (c) not be obliged to disclose to any Obligor or any other person
      any information regarding its tax affairs or tax computations.
<PAGE>
                                       17


            12. Tax Receipts and Mitigation

            12.1 If, at any time, either of the Obligors is required by law to
make any deduction or withholding from any sum payable by it hereunder (or if
thereafter there is any change in the rates at which or the manner in which such
deductions or withholdings are calculated), such Obligor shall promptly notify
the Agent.

            12.2 If either of the Obligors makes any payment hereunder in
respect of which it is required to make any deduction or withholding, it shall
pay the full amount required to be deducted or withheld to the relevant taxation
or other authority within the time allowed for such payment under applicable law
and shall deliver to the Agent for each Bank, within thirty days after it has
made such payment to the applicable authority, an original receipt (or a
certified copy thereof) issued by such authority evidencing the payment to such
authority of all amounts so required to be deducted or withheld in respect of
that Bank's share of such payment.

            12.3 If in respect of any Bank, circumstances arise which would or
would upon the giving of notice result in (i) an increase in the amount of any
payment to be made to it for its account pursuant to Clause 11.1 or (ii) a claim
for indemnification pursuant to Clause 11.2 then, without in any way limiting,
reducing or otherwise qualifying the obligations of the Obligors under this
Agreement, such Bank shall, promptly upon its Facility Office becoming aware of
the same and the possible results thereof, notify the Agent thereof and, in
consultation with the Agent and the Borrower, take such steps as such Bank in
its bona fide opinion considers appropriate to mitigate the effects of such
circumstance including the transfer of its Facility Office to another
jurisdiction or the transfer of its rights and obligations hereunder to another
bank willing to participate in the Facility Provided that such Bank shall be
under no obligation to take any such steps if, in the bona fide opinion of such
Bank, such steps would or might have an adverse effect upon its, or its holding
company's business, operations or financial condition or tax affairs.

            13. Increased Costs

            13.1 if, by reason of (i) any change in law after the date hereof or
in its interpretation or administration and/or (ii) compliance with any request
from or requirement (whether or not having the force of law) of any central bank
(other than, save in the case of (e) below, the requirements of the Bank of
England reflected in the Associated Costs Rate) or other fiscal, monetary or
other authority made or imposed after the date hereof (including, without
limitation, a request or requirement which affects the manner in which a Bank or
any holding company of such Bank is required to or does maintain capital
resources having regard to such Bank's obligations hereunder and to amounts
owing to it hereunder):

            (a) a Bank or any holding company of such Bank incurs a cost as a
      result of such Bank's having entered into and/or performing its
      obligations under this Agreement and/or assuming or maintaining a
      commitment under this Agreement and/or making one or more advances
      hereunder;

            (b) a Bank or any holding company of such Bank is unable to obtain
      the rate of return on its overall capital which it would have been able to
      obtain but for such Bank 
<PAGE>
                                       18


      having entered into and/or performing its obligations and/or assuming or
      maintaining a commitment under this Agreement;

            (c) there is any increase in the cost to a Bank or any holding
      company of such Bank of funding or maintaining all or any of the advances
      comprised in a class of advances formed by or including the advances made
      or to be made by such Bank hereunder;

            (d) a Bank or any holding company of such Bank becomes liable to
      make any payment on account of tax or otherwise (not being a tax imposed
      on the net income of such Bank's Facility Office by the jurisdiction in
      which it is incorporated or in which its Facility Office is located) on or
      calculated by reference to the amount of the advances made or to be made
      by such Bank hereunder and/or to any sum received or receivable by it
      hereunder; or

            (e) the Associated Costs Rate, as calculated hereunder, does not
      represent the cost to a Bank of complying with the requirements of the
      Bank of England in relation to its funding or maintaining of advances
      hereunder,

then the Borrower shall, from time to time on demand of the Agent, promptly pay
to the Agent for the account of that Bank amounts sufficient to indemnify that
Bank or any such holding company against, as the case may be, (1) such cost, (2)
such reduction in such rate of return (or such proportion of such reduction as
is, in the opinion of that Bank, attributable to its obligations hereunder), (3)
such increased cost (or such proportion of such increased cost as is, in the
opinion of that Bank, attributable to its funding or maintaining advances
hereunder), (4) such liability or (5) such portion of such cost as is not
represented by the Associated Costs Rate.

            13.2 A Bank intending to make a claim pursuant to Clause 13.1 shall
no later than 3 months after becoming aware of the event by reason of which it
is entitled to make such claim in relation to any, payments notify the Agent and
the Borrower of the event by reason of which it is entitled to do so Provided
that nothing herein shall require such Bank to disclose any confidential
information relating to the organisation of its affairs.

            14. Illegality

            If, at any time, it is unlawful for a Bank to make, fund or allow to
remain outstanding all or any of the Advances made or to be made by it
hereunder, then that Bank shall, promptly after becoming aware of the same and
where the illegality has not yet occurred notify the Borrower through the Agent
and that Bank and the Agent shall negotiate in good faith with the Borrower with
a view to agreeing substitute terms for participating in the Facility on a
lawful basis. Where the illegality has occurred the relevant Bank shall deliver
to the Borrower through the Agent a certificate to that effect and:

            (i) such Bank shall not thereafter be obliged to make advances
      hereunder and the amount of its Commitment shall be immediately reduced to
      zero; and

            (ii) if the Agent on behalf of such Bank so requires, the Borrower
      shall on such date as the Agent shall have specified repay such Bank's
      share of any 
<PAGE>
                                       19


      outstanding Advances together with accrued interest thereon and all other
      amounts owing to such Bank hereunder.

      its other unsecured creditors save those whose claims are preferred solely
      by any bankruptcy, insolvency, liquidation or other laws of general
      application;

            (iv) in any proceedings taken in Sweden in relation to this

      registration or similar tax be paid on or in relation to this Agreement;

            (viii) the obligations expressed to be assumed by either Obligor in
      this Agreement are legal and valid obligations binding on it enforceable
      in accordance with the terms hereof;
<PAGE>
                                       20


            (ix) it is not necessary under the laws and constitution of Sweden
      (a) in order to enable the Agent, the Arrangers and the Banks or any of
      them to enforce their rights under the Facility Agreement or (b) by reason
      of the execution of the Facility Agreement or the performance by each of

            (x) neither the Agent nor any of the Arrangers or Banks is or will
      be deemed to be resident, domiciled or carrying on business in Sweden by
      reason only of the execution, performance and/or enforcement of the
      Facility Agreement.

            15.2 Each of the Obligors further represents that:

            (i) no member of the Group has taken any corporate action nor have
      any other steps been taken or legal proceedings been started or (to the
      best of the Guarantor's knowledge and belief) threatened against any
      member of the Group for its winding-up, dissolution or administration or
      for the appointment of a receiver, administrator, administrative receiver,
      trustee or similar officer of it or of any or all of its assets or
      revenues;

            (ii) no member of the Group is in breach of or in default under any
      agreement to which it is a party or which is binding on it or any of its
      assets to an extent or in a manner which might have a material adverse
      effect on the business or financial condition of any member of the Group;

            (iii) no action or administrative proceeding of or before any court
      or agency which might have a material adverse effect on the business or
      financial condition of any member of the Group has been started or
      threatened;

            (iv) the Original Financial Statements of the Borrower and the
      Guarantor were prepared in accordance with accounting principles generally
      accepted in Sweden and consistently applied and give (in conjunction with
      the notes thereto) a true and fair view of the financial condition of the
      Borrower, the Guarantor or, as the case may be, the Group at the date as
      of which they were prepared and the results of the Borrower's, the
      Guarantor's or, as the case may be, the Group's operations during the
      financial year then ended;

            (v) at the date hereof amounts which are being or are capable of
      being secured by any existing encumbrances do not in aggregate exceed by
      more than 10 per cent. the amounts disclosed in the Original Financial
      Statements of the Guarantor and stated therein as being secured by any
      encumbrances;

            (vi) since the date to which the Original Financial Statements of
      the Borrower or the Guarantor relate, there has been no material adverse
      change in the business, assets or financial condition of either Obligor,
      which change would give sufficient ground to conclude that either Obligor
      may not or will be unable to, perform or observe its respective
      obligations hereunder;
<PAGE>
                                       21


            (vii) neither the Borrower nor any other member of the Group had, as
      at the date as of which the Original Financial Statements of the Borrower
      or, as the case may be, the Guarantor were prepared, any liabilities
      (contingent or otherwise) which were not disclosed thereby (or by the
      notes thereto) or reserved against therein nor were there at that date any
      unrealised or anticipated losses of the Borrower or, as the case may be,
      any other member of the Group arising from commitments entered into by it
      which were not so disclosed or reserved against;

            (viii) the information contained in the Supplemental Information
      Memorandum and all of the other written information supplied by any member
      of the Group to the Agent, the Arrangers and the Banks in connection
      herewith is true, complete and accurate in all material respects and it is
      not aware of any material facts or circumstances that have not been
      disclosed to the Agent, the Arrangers and the Banks and which might, if
      disclosed, adversely affect the decision of a person considering whether
      or not to provide finance to the Borrower or to provide such finance
      against the security of a guarantee issued by the Guarantor;

            (ix) save as permitted by Clause 17.3, no encumbrance exists over
      all or any of the present or future revenues or assets of the Guarantor or
      the Principal Subsidiaries;

            (x) the execution by each Obligor of this Agreement and such
      Obligor's exercise of its rights and performance of its obligations
      hereunder will not result in the existence of nor oblige any member of the
      Group to create any encumbrance over all or any of its present or future
      revenues or assets;

            (xi) the execution by each Obligor of this Agreement and such
      Obliger's exercise of its rights and performance of its obligations
      hereunder do not and will not:

                  (a)   conflict with any agreement, mortgage, bond or other
                        instrument or treaty to which such Obligor is a party or
                        which is binding upon it or any of its assets;

                  (b)   conflict with such Obligor's certificate of registration
                        and articles of association and internal rules and
                        regulations; or

                  (c)   conflict with any applicable law, regulation or official
                        or judicial order;

            (xii) the execution by each Obligor of this Agreement constitutes,
      and such Obligor's exercise of its rights and performance of its
      obligations hereunder will constitute, private and commercial acts done
      and performed for private and commercial purposes;
<PAGE>
                                       22


            (xiii) each member of the Group maintains insurances on and in
      relation to its business and assets with reputable underwriters or
      insurance companies against such risks and to such extent as is usual for
      companies carrying on a business such as that carried on by such member of
      the Group whose practice is not to self insure;

            (xiv) the Guarantor or one or more directly or indirectly
      wholly-owned subsidiaries of the Guarantor are the legal and beneficial
      owner of, with unencumbered title to, 25 per cent. of the shares and 32.9
      per cent. of the voting rights of Asea AB; and

            (xv) the Borrower is a wholly-owned subsidiary of the Guarantor.

            15.3 The representations in Clauses 15.1 and 15.2 (except
sub-Clauses 15.2 (v) and (viii) shall be deemed to be repeated by each Obligor
on each date on which an Advance is made hereunder as if made with reference to
the facts and circumstances existing at each such date and as if references in
sub-Clauses 15.2 (iv) and 15.2 (vii) were references to the most recent
financial statements delivered to the Agent.

            16.1 Each of the Obligors shall:

            (i) as soon as the same become available, but in any event within

      Agent in sufficient copies for the Banks its financial statements
      (including, in the case of the Guarantor, the consolidated financial

      Consolidated Relevant Total Assets and Total Borrowings at the end of such
      financial year;

            (ii) as soon as the same become available, but in any event within

      statements (including, in the case of the Guarantor, the consolidated
      financial statements of the Group) for such period together with
      certificates signed by a duly authorised officer of the Borrower setting
      out in reasonable detail (a) the names of the Principal Subsidiaries and
      the calculation of Relevant Total Asset, the Consolidated Relevant Total
      Assets and Total Borrowings at the end of such period and (b) the amounts
      of Financial Indebtedness owed by the Guarantor or a Principal Subsidiary
      and allowed pursuant to Clause 17.5 (i) - (v) inclusive; and

            (iii) from time to time on the request of the Agent, furnish the

<PAGE>
                                       23


      unless furnishing such information violates any Swedish law or stock
      exchange regulations.

            16.2 Each of the Obligors shall ensure that:

            (i) each set of financial statements delivered by it pursuant to
      Clause 16.1 is prepared on the same basis as was used in the preparation
      of its Original Financial Statements and in accordance with accounting
      principles generally accepted in Sweden and consistently applied;

            (ii) each set of financial statements delivered by it pursuant to
      Clause 16.1 is certified by a duly authorised officer of such Obligor as

      the Group) is at the end of the period to which those financial statements
      relate and of the results of its (or, as the case may be, the Group's)
      operations during such period; and

            (iii) each set of financial statements delivered by it pursuant to
      paragraph (i) of Clause 16.1 has been audited by an internationally
      recognized firm of independent auditors licensed to practice in Sweden
      provided that should the Agent at any time following consultation with the
      Banks' Swedish Counsel inform any Obligor that it is common practice or a
      requirement for companies comparable to such Obligor to have audited
      financial statements relating to the first half of financial years, then
      the next following, and each subsequent, set of financial statements
      delivered by such Obligor pursuant to (ii) of Clause 16.1 shall also be
      audited by an internationally recognized firm of independent auditors
      licensed to practice in Sweden.

            (i) ensure that each Obligor shall obtain, comply with the terms of
      and do all that is necessary to maintain in full force and effect all
      authorisations, approvals, licenses and consents required in or by the

      evidence in its jurisdiction of incorporation of this Agreement;

            (ii) after the delivery of any Notice of Drawdown and before the
      proposed making of the Advance requested therein, notify the Agent of the

            (iii) ensure that each Obligor shall promptly inform the Agent of
      the occurrence of any Event of Default or Potential Event of Default and,
      upon receipt of a written request to that effect from the Agent, confirm
      to the Agent that, save as previously notified to the Agent or as notified
      in such confirmation, no Event of Default or Potential Event of Default
      has occurred; and

            (iv) ensure that at all times the claims of the Agent, the Arrangers
      and the Banks against it under this Agreement rank at least pari passu

      claims are preferred by any bankruptcy, insolvency, liquidation or other
      similar laws of general application.

            17.2 Each of the Obligors shall ensure that

            (i)   (a)   the Guarantor shall not merge with any person or cease

                        substantially all of its current business

                        if such merger or cessation, as the case may be, would
                        result in a material change of circumstances which might
                        adversely affect the ability of either Obligor to
                        perform its obligations hereunder; or

            (ii) neither the Guarantor nor a Principal Subsidiary shall (save in
      the ordinary course of business) make any loans, grant any credit or give
      any guarantee or indemnity, provide any other financial assistance to or

      Subsidiary or otherwise voluntarily assume any liability, whether actual
      or contingent, in respect of any obligation of any member of the Group
      which is not a Principal Subsidiary.

            17.3 Each of the Obligors shall ensure that neither the Guarantor
nor any Principal Subsidiary shall, without the prior consent of an Instructing
Group, at any time while any amounts remain outstanding from the Borrower or, as
the case may be, may be due from the Guarantor. create or permit to subsist any
encumbrance over all or any of its present or future revenues or assets as
security for any indebtedness of any person other than:

            (i) any encumbrance existing prior to the date hereof provided that
      the principal amount secured thereby may not be subsequently increased;

      of its creation;

            (iii) any encumbrance on goods (including retention of title
      arrangements) or related documents of title and/or other related documents
      arising or created 
<PAGE>

      directly relating to such goods or documents of title and/or other related
      documents or services to be provided in connection with such goods;

            (iv) any encumbrance on goods, or related documents of title and/or

      Subsidiary of the Guarantor after the date of this Agreement, (a) any
      encumbrance existing on or over its assets when it becomes or, as the case
      my be, became a subsidiary and not created in contemplation of or in
      connection with it becoming a subsidiary and (b) any encumbrance existing
      on or over its assets when it becomes a Principal Subsidiary which was
      created after the date of it becoming a subsidiary but not in

      (tvangsinlosen) to the Guarantor or a Principal Subsidiary;

            (ix) any encumbrance created by the Guarantor or a Principal

      provisions of Clause 17.5 (iii) provided such Group Pension Fund requires
      such encumbrance to be created and refuses to accept a guarantee or other
      support from the Guarantor or the parent company of the relevant Principal
      Subsidiary as applicable, in order to make such borrowings available;

      Principal Subsidiary enter into back to back, foreign exchange, swap or
      derivative transactions in the ordinary course of business and which cash
      has to be deposited in order for such transactions to be entered into,
      provided that the amount of cash so encumbered (a) does not at any time
      exceed 20 per cent. of the aggregate exposure of the relevant
      counterparties to the Guarantor or a Principal Subsidiary under such
      transactions at such time or (b) does not at any time exceed 10 per cent.
      of consolidated total assets of the Group as shown in the latest audited
      consolidated accounts of the Guarantor; and

            (xi) any other encumbrances other than those referred to in
      sub-paragraphs (i) - (x) above, over or affecting assets the aggregate
      book value of which is less than five per cent. (5%) of the book value of
      the total assets of the Group as shown in the most recent audited
      consolidated financial statements of the Guarantor (adjusted from time to
      time to take into account acquisitions and/or disposals after the date to
      which such financial statements relate);

      Provided that the Guarantor shall not create or permit to subsist and
      shall procure that no permitted owner under Clause 15.2 (xiv) shall create
      or permit to subsist (i) any encumbrance over the shares or over the
      voting rights held by it in ASEA AB and (ii) any encumbrance securing any
      indebtedness of any Obligor under a LC Agreement.

            17.4 Each Obligor shall ensure that neither the Guarantor nor any
Principal Subsidiary shall, without the prior consent of an Instructing Group,
either in a single transaction or in a series of transactions, whether related
or not and whether voluntarily or involuntarily, sell, transfer, grant or lease
or other-wise dispose of all or any part of its assets, other than

            (i) a disposal of assets on an arm's length basis for market value;

            (ii) a disposal under short term sale and repurchase transactions by
      the Borrower with banks or other financial institutions which transact
      such business on a regular basis on market terms and in respect of
      marketable securities (other than ASEA AB shares) held by the Borrower for
      investment purposes;

            (iii) a disposal of assets in any one financial year the aggregate
      book value of which is less than 5 % of the total assets of the Group as
      shown in the then most recent audited consolidated financial statements
      (adjusted from time to time to take into account acquisitions and/or
      disposal after the date to which such financial statements relate); or

            (iv) a disposal of assets from a Principal Subsidiary (other than
      the Borrower) to another Principal Subsidiary,
<PAGE>
                                       27


            Provided that the Guarantor shall not (unless to a permitted owner
under Clause 15.2 (xiv)) and shall procure that a permitted owner under Clause
15.2 (xiv) shall not without the consent of all the Banks sell, transfer, grant
or lease or otherwise dispose of any of the shares or any of the voting rights
in ASEA AB (at 25 per cent. and 32.9 per cent. respectively) unless such sale,
transfer, grant, lease or other disposal is on an arm's length basis and
sufficient proceeds thereof are remitted directly to the Agent and deposited
with the Agent in a blocked account (which shall be an account bearing interest
at the best available rate quoted by the Agent for such accounts at such time)
so that the amount standing to the credit of such blocked account together with
any other amounts deposited therein (if necessary) by the Borrower or the
Guarantor is at least equal to the Loan and any other amounts outstanding
hereunder; and

            Provided further that promptly but in any case within 5 business
days of such remittance and deposit in the blocked account the Agent shall
notify each Bank thereof and within 30 business days of such notification by the
Agent each Bank shall irrevocably notify the Agent whether or not it wishes to
continue to participate in the Facility (which a Bank may decide in its sole
discretion). If a Bank (a "Retiring Bank") notifies the Agent that it no longer
wishes to continue to participate in the Facility, then the Agent shall promptly
cancel such Retiring Bank's Commitment and the Borrower shall within 30 business
days of such Retiring Bank's notification repay such Retiring Bank's share of
the Loan together with all other amounts outstanding hereunder to such Retiring
Bank (and the Agent shall apply, at the request of the Borrower, amounts
standing to the credit of the blocked account for the purpose of such
repayment). Upon cancellation and repayment of all Retiring Banks the Agent
shall release any remaining balance standing to the credit of the blocked
account to the Borrower; and

            Provided further that an Advance shall not be made hereunder during
the period starting on the date of the remittance and deposit of sufficient
amounts in the blocked account and ending on the earlier of, 40 business days
thereafter or, the date upon which any remaining balance standing to the credit
of the blocked account is released by the Agent pursuant hereto.

            17.5 Each Obligor shall ensure that no Principal Subsidiary (other
than the Borrower and its Financing Subsidiaries) will incur or permit to
subsist any Financial Indebtedness with any bank or other institution providing
banking services other than

            (i) Financial Indebtedness owing by a member of the Group to another
      member of the Group; or

            (ii) Financial Indebtedness not exceeding Swedish Kronor
      2,000,000,000 of Nybrovikens Kraft AB to the National Pension Insurance
      Fund in connection with the purchase by Nybrovikens Kraft AB of hydropower
      assets from the National Pension Insurance Fund; or

            (iii) Financial Indebtedness of the Guarantor or a Principal
      Subsidiary to a Group Pension Fund where such Financial Indebtedness is in
      the form of reborrowing from such Group Pension of pension funds deposited
      with such Group Pension Fund and provided such Financials Indebtedness in
      aggregate in respect of the Guarantor and the Principal Subsidiaries shall
      not exceed Swedish Kronor 300,000,000; or

            (iv) Financial indebtedness of Gambro; or
<PAGE>
                                       28


            (v) Financial Indebtedness (other than that referred to in
      sub-paragraphs (i), (ii), (iii) or (iv) above) of subsidiaries not
      exceeding in aggregate the higher of 20 per cent. of Total Borrowings and
      Swedish Kronor 1,000,000,000

            Provided that in the case of a company or corporation becoming a
Principal Subsidiary after the date hereof the above shall not apply in respect
of Financial Indebtedness existing on the date of such company or corporation
becoming a Principal Subsidiary (which was not incurred in contemplation or in
connection with it becoming a Principal Subsidiary) until the first anniversary
of such date.

            17.6 Each Obligor shall ensure that no permitted owner under clause
15.2 (xiv) (other than the Guarantor) of the shares or any of the voting rights
of ASEA AB will incur or permit to subsist any Financial Indebtedness other than
Financial Indebtedness to another member of the Group.

            18. Events of Default

            18.1 If:

            (i) either of the Obligors shall fail to pay when due any sum which
      shall have become due hereunder and, if the non-payment is solely due to
      technical or administrative reasons the non-payment continues unremedied

      within 30 days of being levied against, or an encumbrancer takes
      possession of the whole or any part of, the property, undertaking or
      assets of the Guarantor or any Material Subsidiary; or

            (ix) by or under the authority of any government, (a) the management

            (xiv) a material adverse change occurs in the business, assets or
      financial condition of either Obligor, which change gives, in the
      reasonable opinion of an Instructing Group, sufficient grounds to conclude
      that either Obligor may not, or will be unable to, perform or observe its
      respective obligations hereunder,

then, and in any such case and at any time thereafter, the Agent may (and, if so
instructed by an Instructing Group, shall) by written notice to the Borrower:

      (a)   declare the Advances to be immediately due and payable (whereupon
            the same shall become so payable together with accrued interest
            thereon and any other sums then owed by the Borrower hereunder) or
            declare the Advances to be due and payable on demand of the Agent;
            and/or

      (b)   declare that the Facility shall be cancelled, whereupon these shall
            be cancelled and the Commitment of each Bank shall be reduced to
            zero.

            18.2 If, pursuant to Clause 18.1, the Agent declares the Advances to
be due and payable on demand of the Agent, then, and at any time thereafter, the
Agent may (and, if so instructed by in Instructing Group, shall) by written
notice to the Borrower call for repayment of the Advances on such date as it may
specify in such notice (whereupon the same shall become due and payable on such
date together with accrued interest thereon and any other sums then owed by the
Borrower hereunder) or withdraw its declaration with effect from such date as it
may specify in such notice.

            18.3 If, pursuant to Clause l8.l(a), the Agent declares the Advances
to be due and payable on demand, the Term in respect of any such Advance shall,
if the Agent subsequently demands payment before the scheduled Repayment Date in
respect of such Advance, be deemed (except for the purposes of Clause 21.4) to
be of such length that it ends on the date that such demand is made.

                                     Part 8

                                    GUARANTEE

            19. Guarantee

            The Guarantor hereby irrevocably and unconditionally:

            (i) guarantees to the Agent, the Arrangers and the Banks the due and
      punctual observance and performance of all the terms, conditions and
      covenants on the part of the Borrower contained in this Agreement and
      agrees to pay to the Agent from time to time on demand any and every sum
      or sums of money which the Borrower shall at any time be liable to pay to

      of them as a result of any of the obligations of the Borrower under or
      pursuant to this Agreement being or becoming void, voidable, unenforceable
      or ineffective as against the Borrower for any reason whatsoever, whether
      or not known to the Agent, the Arrangers and the Banks or any of them or
      any other person, the amount of such loss being the amount which the
      person or persons suffering it would otherwise have been entitled to
      recover from the Borrower.

            20. Preservation of Rights

            20.1 The obligations of the Guarantor herein contained shall be in
addition to and independent of every other security which the Agent, the
Arrangers and the Banks or any of them may at any time hold in respect of any of
the Borrower's obligations hereunder.

            20.2 The obligations of the Guarantor herein contained shall
constitute and be continuing obligations notwithstanding any settlement of
account or other matter or thing whatsoever, and in particular but without
limitation, shall not be considered satisfied by any intermediate payment or
satisfaction of all or any of the obligations of the Borrower under this
Agreement and shall continue in full force and effect until final payment in
full of all amounts owing by the Borrower hereunder and total satisfaction of
all the Borrower's actual and contingent obligations hereunder.

            20.3 Neither the obligations of the Guarantor herein contained nor
the rights, powers and remedies conferred in respect of the Guarantor upon the
Agent, the Arrangers and the Banks or any of them by this Agreement or by law
shall be discharged, impaired or otherwise affected by:

            (i) the winding-up, dissolution, administration or re-organisation
      of the Borrower or any other person or any change in its status, function,
      control or ownership;
<PAGE>
                                       32


            (ii) any of the obligations of the Borrower or any other person
      hereunder or under any other security taken in respect of any of its
      obligations hereunder being or becoming illegal, invalid, unenforceable or
      ineffective in any respect;

            (iii) time or other indulgence being granted or agreed to be granted
      to the Borrower in respect of its obligations hereunder or under any such
      other security;

            (iv) any amendment to, or any variation, waiver or release of, any
      obligation of the Borrower hereunder or under any such other security;

            (v) any failure to take, or fully to take, any security contemplated
      hereby or otherwise agreed to be taken in respect of the Borrower's
      obligations hereunder;

            (vi) any failure to realise or fully to realise the value of, or any
      release, discharge, exchange or substitution of, any security taken in
      respect of the Borrower's obligations hereunder; or

            (vii) any other act, event or omission which, but for this Clause
      20.3, might operate to discharge, impair or otherwise affect any of the
      obligations of the Guarantor herein contained or any of the rights, powers
      or remedies conferred upon the Agent, the Arrangers and the Banks or any
      of them by this Agreement or by law.

            20.4 Any settlement or discharge between the Guarantor and the
Agent, the Arrangers and the Banks or any of them shall be conditional upon no
security or payment to the Agent, the Arrangers and the Banks or any of them by
the Borrower or the Guarantor or any other person on behalf of the Borrower or,
as the case may be, the Guarantor being avoided or reduced by virtue of any
provisions or enactments relating to bankruptcy, insolvency, liquidation or
similar laws of general application for the time being in force and, if any such
security or payment is so voided or reduced, the Agent, the Arrangers and the
Banks shall each be entitled to recover the value or amount of such security or
payment from the Guarantor subsequently as if such settlement or discharge had
not occurred.

            20.5 Neither the Agent, the Arrangers and the Banks nor, any of them
shall be obliged before exercising any of the rights, powers or remedies
conferred upon them in respect of the Guarantor by this Agreement or by law:

            (i) to make any demand of the Borrower;

            (ii) to take any action or obtain judgment in any court against the
      Borrower;

            (iii) to make or file any claim or proof in a winding-up or
      dissolution of the Borrower; or

                                       33


            (iv) to enforce or seek to enforce any other security taken in
      respect of any of the obligations of the Borrower hereunder.

            20.6 The Guarantor agrees that, so long as any amounts are or may be
owed by the Borrower hereunder or the Borrower is under any actual or contingent
obligations hereunder, the Guarantor shall not exercise any rights which the
Guarantor may at any time have by reason of performance by it of its obligations
hereunder:

            (i) to be indemnified by the Borrower; and/or

            (ii) to claim any contribution from any other guarantor of the
      Borrower's obligations hereunder; and/or

            (iii) to take the benefit (in whole or in part and whether by way of
      subrogation or otherwise) of any rights of the Agent, the Arrangers and
      the Banks hereunder or of any other security taken pursuant to, or in
      connection with, this Agreement by all or any of the Agent, the Arrangers
      and the Banks.

                                     Part 9

                         DEFAULT INTEREST AND INDEMNITY

            21. Default Interest and Indemnity

            21.1 If any sum due and payable by either of the Obligors hereunder
is not paid on the due date therefor in accordance with the provisions of Clause
23 or if any sum due and payable by either of the Obligors under any judgment of
any court in connection herewith is not paid on the date of such judgment, the
period beginning on such due date or, as the case may be, the date of such
judgment and ending on the date upon which the obligation of such Obligor to pay
such sum (the balance thereof for the time being unpaid being herein referred to
as an "unpaid sum") is discharged shall be divided into successive periods, each
of which (other than the first) shall start on the last day of the preceding
such period and the duration of each of which shall (except as otherwise
provided in this Clause 21) be selected by the Agent.

            21.2 During each such period relating thereto as is mentioned in
Clause 21.1 an unpaid sum shall bear interest at the rate per annum which is the
sum from time to time of one per cent., the Margin (and, in the case of any such
sum denominated in sterling, the Associated Costs Rate in respect thereof at
such time) and LIBOR on the Quotation Date therefor Provided that:

            (i) if, for any such period, LIBOR cannot be determined, the rate of
      interest applicable to such unpaid sum shall be the sum from time to time
      of one per cent., the Margin (and, in the case of any such sum denominated
      in sterling, the Associated Costs Rate in respect thereof at such time)
      and the rate per annum determined by the Agent to be the weighted
      arithmetic mean (rounded upwards, if not already such a multiple, to the
      nearest whole multiple of one-sixteenth of one per cent.) of the rates
      notified by each Bank to the Agent before the last day of such period to
      be those which express as a percentage rate per annum the cost to it of
      funding from whatever source it may select its portion of such unpaid sum
      for such period; and

            (ii) if such unpaid sum is all or part of an Advance which became
      due and payable on a day other than the last day of the Term thereof, the
      first such period applicable thereto shall be of a duration equal to the
      unexpired portion of that Term and the rate of interest applicable thereto
      from time to time during such period shall be that which exceeds by one
      per cent. the rate which would have been applicable to it had it not so
      fallen due.

            21.3 Any interest which shall have accrued under Clause 21.2 in
respect of an unpaid sum shall be due and payable and shall be paid by the
Obligor owing such unpaid sum at the end of the period by reference to which it
is calculated or on such other date or dates as the Agent may specify by written
notice to such Obligor.

            21.4 If any Bank or the Agent on its behalf receives or recovers all
or any part of such Bank's share of an Advance otherwise than on the last day of
the Term thereof, the Borrower shall pay to the Agent on demand for account of
such Bank an amount equal to the amount (if any) by which (i) 
<PAGE>
                                       35


the additional interest which would have been payable on the amount so received
or recovered had it been received or recovered on the last day of the Term
thereof exceeds (ii) the amount of interest which in the opinion of the Agent
would have been payable to the Agent on the last day of the Term thereof in
respect of a deposit in the currency of the amount so received or recovered
equal to the amount so received or recovered placed by it with a prime bank in
London for a period starting on the third business day following the date of
such receipt or recovery and ending on the last day of the Term thereof.

            21.5 The Borrower undertakes to indemnify:

            (i) each of the Agent, the Arrangers and the Banks against any cost,
      claim, loss, expense (including legal fees) or liability together with any
      VAT thereon, which any of them may sustain or incur as a consequence of
      the occurrence of any Event of Default or any default by the Borrower in
      the performance of any of the obligations expressed to be assumed by it in
      this Agreement;

            (ii) the Agent against any loss it may suffer as a result of its
      entering into, or performing, any foreign exchange contract for the
      purposes of Part 10;

            (iii) each Bank against any loss it may suffer as a result of its
      funding its portion of an Advance requested by the Borrower hereunder but
      not made by reason of the operation of any one or more of the provisions
      hereof; and

            (iv) each Bank against any loss it may suffer as a result of an
      Advance having been requested in an Optional Currency and such Bank
      funding its portion of such Advance in such Optional Currency but such
      Advance being denominated in dollars and being made in dollars by reason
      of the provisions of Clause 6.5(ii).

            21.6 Any unpaid sum shall (for the purposes of this Clause 21,
Clause 13.1 and the Sixth Schedule) be treated as an advance and accordingly in
this Clause 21 and the Sixth Schedule the term "Advance" includes any unpaid sum
and "Term", in relation to an unpaid sum, includes each such period relating
thereto as is mentioned in Clause 21.1.

                                     Part 10

                                    PAYMENTS

            22. Currency of Account and Payment

            22.1 The dollar is the currency of account and payment for each and
every sum at any time due from either of the Obligors hereunder Provided that:

            (i) each repayment of an Advance or a part thereof shall be made in
      the currency in which such Advance is denominated at the time of that
      repayment;

            (ii) each payment of interest shall be made in the currency in which
      the sum in respect of which such interest is payable is denominated;

            (iii) each payment in respect of costs and expenses shall be made in
      the currency in which the same were incurred;

            (iv) each payment pursuant to Clause 11.2 or Clause 13.1 shall be
      made in the currency specified by the party claiming thereunder; and

            (v) any amount expressed to be payable in a currency other than
      dollars shall be paid in that other currency.

            22.2 If the Agent at any time determines (after consultation with
the Reference Banks and the Banks) that:

            (i) for reasons affecting the market in ECU generally, ECU are not
      freely available in the International Interbank Market;

            (ii) the ECU has ceased to be utilised as the basic accounting unit
      of the European Union;

            (iii) the ECU has ceased to be used in the European Monetary System;
      or

            (iv) it is illegal, impossible or impracticable for payments to be
      made hereunder in ECU,

then the Agent may, in its discretion, but after consultation with the Borrower
and the Banks, declare (such declaration to be binding on all the parties
hereto) that the repayment of any Advance denominated in ECU and any payment of
interest thereon that is due and unpaid at the time of, or becomes due after,
such declaration shall be made in a specified component currency, in which case
the amount so to be paid in such component currency shall be computed on the
basis of the equivalent of the ECU in such component currency determined in
accordance with the provisions of the Fifth Schedule.

                                       37


            22.3 If any sum due from either of the Obligors under this Agreement
or any order or judgment given or made in relation hereto has to be converted
from the currency (the "first currency') in which the same is payable hereunder
or under such order or judgment into another currency (the "second currency")
for the purpose of (i) making or filing a claim or proof against such Obligor,
(ii) obtaining an order or judgment in any court or other tribunal or (iii)
enforcing any order or judgment given or made in relation hereto, the Borrower
shall indemnify and hold harmless each of the persons to whom such sum is due
from and against any loss suffered as a result of any discrepancy between (a)
the rate of exchange used for such purpose to convert the sum in question from
the first currency into the second currency and (b) the rate or rates of
exchange at which such person may in the ordinary course of business purchase
the first currency with the second currency upon receipt of a sum paid to it in
satisfaction, in whole or in part, of any such order, judgment, claim or proof.

            23. Payments

            23.1 On each date on which this Agreement requires an amount to be
paid by either of the Obligors or any of the Banks hereunder, such Obligor or,
as the case may be, such Bank shall make the same available to the Agent:

            (i) where such amount is denominated in dollars, by payment in
      dollars and in same day funds (or in such other funds as may for the time
      being be customary in New York City for the settlement in New York City of
      international banking transactions in dollars) to the Agent's account
      number 107 001 200 123 chips id: 132262 with Deutsche Bank AG, New York
      Branch, P.0. Box 890, New York, N.Y. 10101-0890 U.S.A. (or such other
      account or bank as the Agent may have specified for this purpose); or

            (ii) where such amount is denominated in an Optional Currency, by
      payment in such Optional Currency and in immediately available, freely
      transferable, cleared funds to such account with such bank in the
      principal financial centre of the country of such Optional Currency (or,
      in the case of ECU, Frankfurt am Main) as the Agent shall have specified
      for this purpose.

            23.2 If, at any time, it shall become impracticable (by reason of
any action of any governmental authority or any change in law, exchange control
regulations or any similar event) for either of the Obligors to make any
payments hereunder in the manner specified in Clause 23.1. then such Obligor may
agree with each or any of the Banks alternative arrangements for the payment
direct to such Bank of amounts due to such Bank hereunder Provided that, in the
absence of any such agreement with any Bank, such Obligor shall be obliged to
make all payments due to such Bank in the manner specified herein. Upon reaching
such agreement such Obligor and such Bank shall immediately notify the Agent
thereof and shall thereafter promptly notify the Agent of all payments made
direct to such Bank.

            23.3 Save as otherwise provided herein, each payment received by the
Agent for the account of another person pursuant to Clause 23.1 shall:
<PAGE>
                                       38


            (i) in the case of a payment received for the account of the
      Borrower, be made available by the Agent to the Borrower by application:

                  (a)   first, in or towards payment (on the date, and in the
                        currency and funds, of receipt) of any amount then due
                        from the Borrower hereunder to the person from whom the
                        amount was so received or in or towards the purchase of
                        any amount of any currency to be so applied; and

                  (b)   secondly, in or towards payment (on the date, and in the
                        currency and funds, of receipt) to such account with
                        such bank in the principal financial centre of the
                        country of the currency of such payment (or, in the case
                        of ECU, Brussels) as the Borrower shall have previously
                        notified to the Agent for this purpose; and

            (ii) in the case of any other payment, be made available by the
      Agent to the person for whose account such payment was received (in the
      case of a Bank, for the account of the Facility Office) for value the same
      day by transfer to such account of such person with such bank in the
      principal financial centre of the country of the currency of such payment
      as such person shall have previously notified to the Agent or in the case
      of ECU such financial centre for payment of ECU as such person shall have
      previously notified to the Agent.

            23.4 All payments required to be made by either of the Obligors
hereunder shall be calculated without reference to any set-off or counterclaim
and shall be made free and clear of and without any deduction for or on account
of any set-off or counterclaim.

            23.5 All moneys received, recovered or realised by a Bank by virtue
of Clause 19 may, in that Bank's discretion, be credited to a suspense or
impersonal account and may be held in such account for so long as such Bank
thinks fit pending the application from time to time (as such Bank may think
fit) of such moneys in or towards the payment and discharge of any amounts owing
by either of the Obligors to such Bank hereunder.

            23.6 Where a sum is to be paid hereunder to the Agent for account of
another person, the Agent shall not be obliged to make the same available to
that other person or to enter into or perform any exchange contract in
connection therewith until it has been able to establish to its satisfaction
that it has actually received such sum, but if it does so and it proves to be
the case that it had not actually received such sum, then the person to whom
such sum or the proceeds of such exchange contract was so made available shall
on request refund the same to the Agent together with an amount sufficient to
indemnify the Agent against any cost or loss it may have suffered or incurred by
reason of its having paid out such sum or the proceeds of such exchange contract
prior to its having received such sum.

            24. Set-Off

            Each of the Obligors authorises each Bank to apply any credit
balance to which such Obligor is entitled on any account of such Obligor with
that Bank in satisfaction of any sum due and payable from such Obligor to such
Bank hereunder but unpaid; for this purpose, each Bank is authorised to purchase
with the moneys standing to the credit of any such account such other currencies
as may be necessary to effect such application. No Bank shall be obliged to
exercise any right given to it by this Clause 24.

            25. Redistribution of Payments

            25.1 If, at any time, the proportion which any Bank (a "Recovering
Bank") has received or recovered (whether by payment, the exercise of a right of
set-off or combination of accounts or otherwise) in respect of its portion of
any payment (a "relevant payment") to be made under this Agreement by either of
the Obligors for account of such Recovering Bank and one or more other Banks is
greater (the portion of such receipt or recovery giving rise to such excess
proportion being herein called an "excess amount") than the proportion thereof
so received or recovered by the Bank or Banks so receiving or recovering the
smallest proportion thereof, then:

            (i) such Recovering Bank shall pay to the Agent an amount equal to
      such excess amount;

            (ii) there shall thereupon fall due from such Obligor to such
      Recovering Bank an amount equal to the amount paid out by such Recovering
      Bank pursuant to paragraph (i) above, the amount so due being, for the
      purposes hereof, treated as if it were an unpaid part of such Recovering
      Bank's portion of such relevant payment; and

            (iii) the Agent shall treat the amount received by it from such
      Recovering Bank pursuant to paragraph (i) above as if such amount had been
      received by it from such Obligor in respect of such relevant payment and
      shall pay the same to the persons entitled thereto (including such
      Recovering Bank) pro rata to their respective entitlements thereto,

Provided that to the extent that any excess amount is attributable to a payment
to a Bank pursuant to Clause 23.3(i)(a) such portion of such excess amount as is
so attributable shall not be required to be shared pursuant hereto.

            25.2 If any sum (a "relevant sum") received or recovered by a
Recovering Bank in respect of any amount owing to it by either of the Obligors
becomes repayable and is repaid by such Recovering Bank, then:

            (i) each Bank which has received a share of such relevant sum by
      reason of the implementation of Clause 25.1 shall, upon request of the
      Agent, pay to the Agent for account of such Recovering Bank an amount
      equal to its share of such relevant sum together with its share of such
      amount (if any) as is necessary to reimburse the Recovering Bank for any
      interest it shall have 
<PAGE>
                                       40


      been obliged to pay to either of the Obligors in respect thereof when
      repaying such relevant sum to such Obligor; and

            (ii) there shall thereupon fall due from such Obligor to each such
      Bank an amount equal to the amount paid out by it pursuant to paragraph
      (i) above, the amount so due being, for the purposes hereof, treated as if
      it were the sum payable to such Bank against which such Bank's share of
      such relevant sum was applied.

            25.3 A Bank shall not be obliged to share any amount pursuant to
clause 25.1 if it has received or recovered such amount as a result of any legal
proceedings with any other Bank which had an opportunity to participate in those
legal proceedings but did not do so and did not separately take equivalent legal
proceedings.

to day during the period beginning on the date hereof and ending on the Final
Maturity Date, such commitment commission to be calculated at the rate of 0.10
per cent. per annum for the period beginning on the date hereof and ending on
the date falling 48 months after the date hereof and thereafter at the rate of
0.125 per cent per annum and such commitment commission to be payable in arrear

            26.3 The Borrower shall pay to the Agent for its own account the
agency fee specified in the letter of even date herewith from the Arrangers to

            26.4 The Borrower shall, in the event the Facility is utilised, pay

Commitments, a utilisation fee in dollars computed on the total drawn amount of
the Total Commitments during the period from the date the Facility is first
utilised to and including the Final Maturity Date at the rate of 0.025 per cent.
per annum if the total drawn amount of the Total Commitments is equivalent to
between 33 per cent. and 67 per cent. (inclusive) of the Total Commitment and at
the rate of 0.05 per cent. per annum if the total drawn amount of the Total
Commitment exceeds 67 per cent. of the Total Commitments. Accrued utilisation

connection with the negotiation, preparation and execution of this Agreement and
the completion of the transactions herein contemplated.

            27.2 The Borrower shall, from time to time on demand of the Agent,
reimburse the Agent, the Arrangers and the Banks for all reasonable costs and

connection with the preservation and/or enforcement of any of the rights of the
Agent, the Arrangers and the Banks under this Agreement.

            27.3 The Borrower shall pay all stamp registration and other taxes
to which this Agreement or any judgment given in connection herewith is or at

liabilities, costs, claims and expenses resulting from any failure to pay or any
delay in paying any such tax.

            27.4 If the Borrower fails to perform any of its obligations under
this Clause 27, each Bank shall, in its Proportion, indemnify each of the Agent
and the Arrangers against any loss incurred by any of them as a result of such
failure and the Borrower shall forthwith reimburse each Bank for any payment
made by it pursuant to this Clause 27.4.

                                AGENCY PROVISIONS

            28. The Agent, the Arrangers and the Banks

            28.1 Each Arranger and each Bank hereby appoints the Agent to act as
its agent in connection herewith and authorises the Agent to exercise such

Agent by the terms hereof together with all such rights, powers, authorities and
discretions as are reasonably incidental thereto.

            28.2 The Agent may:

                  (i) assume that:

                        (a) any representation made by either of the Obligors in
                  connection herewith is true;

                        (b) no Event of Default or Potential Event of Default
                  has occurred;

                        (c) neither of the Obligors is in breach of or default
                  under its obligations hereunder; and

                        (d) any right, power, authority or discretion vested
                  herein upon an Instructing Group, the Banks or any other
                  person or group of persons has not been exercised,

                  unless it has, in its capacity as agent for the Banks,
                  received notice to the contrary from any other party hereto or
                  (in case of a payment default hereunder) gained actual
                  acknowledge to the contrary;

                  (ii) assume that the Facility Office of each Bank is that
            identified with its signature below (or, in the case of a
            Transferee, at the end of the Transfer Certificate to which it is a
            party as Transferee) until it has received from such Bank a notice
            designating some other office of such Bank to replace its Facility
            Office and act upon any such notice until the same is superseded by
            a further such notice;

                  (iii) engage and pay for the advice or services of any
            lawyers, accountants, surveyors or other experts whose advice or

            upon any advice so obtained;

                  (iv) rely as to any matters of fact which might reasonably be
            expected to be within the knowledge of either of the Obligors upon a
            certificate signed by or on behalf of such Obligor;

                  (v) rely upon any communication or document believed by it to
            be genuine;
<PAGE>
                                       44


                  (vi) refrain from exercising any right, power or discretion
            vested in it as agent hereunder unless and until instructed by an
            Instructing Group as to whether or not such right, power or
            discretion is to be exercised and, if it is to be exercised, as to
            the manner in which it should be exercised;

                  (vii) refrain from beginning any legal action or proceeding in
            connection with this Agreement on behalf of any Bank until such Bank
            has given its written consent thereto;

            of an Instructing Group to begin any legal action or proceeding
            arising out of or in connection with this Agreement until it shall
            have received such security as it may require (whether by way of
            payment in advance or otherwise) for all costs, claims, losses,
            expenses (including legal fees) and liabilities together with any
            VAT thereon which it will or may expend or incur in complying with
            such instructions; and

                  (ix) if it is unable to obtain instructions or communicate
            with a Bank after making reasonable attempts to do so, either
            refrain from acting as Agent on behalf of such Bank or take such
            action on behalf of such Bank as it in its absolute discretion deems
            appropriate and reasonable and shall not be liable to such Bank as a
            result of any such action or inaction.

            28.3 The Agent shall:

                  (i) promptly inform each Bank of the contents of any notice or
            document received by it in its capacity as Agent from either of the
            Obligors hereunder;

                  (ii) promptly notify each Bank of the occurrence of any Event
            of Default or any default by either of the Obligors in the due
            performance of or compliance with its obligations under this
            Agreement of which the Agent, in its capacity as agent for the
            Banks, has received express notice from any other party hereto or
            (in the case of a payment default hereunder) gained actual
            knowledge;

                  (iii) save as otherwise provided herein, act as agent
            hereunder in accordance with any instructions given to it by an
            Instructing Group, which instructions shall be binding on all of the
            Arrangers and the Banks; and

                  (iv) if so instructed by an Instructing Group, refrain from
            exercising any right, power or discretion vested in it as agent
            hereunder.

            28.4 Notwithstanding anything to the contrary expressed or implied
herein, neither the Agent nor any of the Arrangers shall:
<PAGE>
                                       45


                  (i) be bound to enquire as to:

                        (a) whether or not any representation made by either of
                  the Obligors in connection herewith is true;

                        (b) the occurrence or otherwise of any Event of Default
                  or Potential Event of Default;

                        (c) the performance by either of the Obligors of its
                  obligations hereunder; or

                        (d) any breach of or default by either of the Obligors
                  of or under its obligations hereunder;

                  (ii) be bound to account to any Bank for any sum or the profit
            element of any sum received by it for its own account;

                  (iii) be bound to disclose to any other person any information
            relating to any member of the Group if such disclosure would or
            might in its opinion constitute a breach of any law or regulation or
            be otherwise actionable at the suit of any person; or

                  (iv) be under any obligations other than those for which
            express provision is made herein.

            28.5 Each Bank shall, in its Proportion, from time to time on demand
by the Agent, indemnify the Agent (to the extent the Agent has not previously
been indemnified by the Borrower), against any and all costs, claims, losses,
expenses (including legal fees) and liabilities together with any VAT thereon
which the Agent may incur, otherwise than by reason of its own gross negligence
or wilful misconduct, in acting in its capacity as agent hereunder.

            28.6 Neither the Agent and the Arrangers nor any of them accepts any
responsibility for the accuracy and/or completeness of the Supplemental
Information Memorandum or any other information supplied by either of the
Obligors in connection herewith or for the legality, validity, effectiveness,
adequacy or enforceability of this Agreement and neither the Agent and the
Arrangers nor any of them shall be under any liability as a result of taking or
omitting to take any action in relation to this Agreement, save in the case of
gross negligence or wilful misconduct.

            28.7 Each of the Banks agree that it will not assert or seek to
assert against any director, officer or employee of the Agent or any Arranger
any claim it might have against any of them in respect of the matters referred
to in Clause 28.6.

            28.8 The Agent and each of the Arrangers may accept deposits from,
lend money to and generally engage in any kind of banking or other business with
any member of the Group.

            28.9 The Agent may resign its appointment hereunder at any time
without assigning any reason therefor by giving not less than thirty days' prior
written notice to that effect to each of the other 
<PAGE>
                                       46


parties hereto or an Instructing Group may at any time terminate the appointment
of the Agent by giving not less than sixty days' prior written notice to the
Agent, copied to all parties hereto, Provided that no such resignation or
termination shall be effective until a successor for the Agent is appointed in
accordance with the succeeding provisions of this Clause 28.

            28.10 If the Agent gives notice of its resignation, or its
appointment is terminated, pursuant to Clause 28.9, then any reputable and
experienced bank or other financial institution may be appointed as a successor
to the Agent by an Instructing Group during the period of such notice but, if no
such successor is so appointed, the Agent may appoint such a successor itself
which shall be a reputable and experienced bank or other financial institution.

            28.11 If a successor to the Agent is appointed under the provisions
of Clause 28.10, then (i) the retiring Agent shall be discharged from any
further obligation hereunder but shall remain entitled to the benefit of the
provisions of this Clause 28 and (ii) its successor and each of the other
parties hereto shall have the same rights and obligations amongst themselves as
they would have had if such successor had been a party hereto.

            28.12 It is understood and agreed by each Bank that it has itself
been, and will continue to be, solely responsible for making its own independent
appraisal of and investigations into the financial condition, creditworthiness,
condition, affairs, status and nature of each member of the Group and,
accordingly, each Bank warrants to the Agent and the Arrangers that it has not
relied on and will not hereafter rely on the Agent and the Arrangers nor any of
them:

            (i) to check or enquire on its behalf into the adequacy, accuracy or
      completeness of any information provided by either of the Obligors in
      connection with this Agreement or the transactions herein contemplated
      (whether or not such information has been or is hereafter circulated to
      such Bank by the Agent and the Arrangers or any of them); or

            (ii) to assess or keep under review on its behalf the financial
      condition, creditworthiness, condition, affairs, status or nature of any
      member of the Group.

            28.13 In acting as Agent for the Banks, the Agent's agency division
shall be treated as a separate entity from any other of its divisions or
departments and, notwithstanding the foregoing provisions of this Clause 28, in
the event that the Agent should act for any member of the Group in any capacity
in relation to any other matter, any information given by such member of the
Group to the Agent in such other capacity may be treated as confidential by the
Agent.

                                     Part 13

                            ASSIGNMENTS AND TRANSFERS

            29. Benefit of Agreement

            This Agreement shall be binding upon and ensure to the benefit of
each party hereto and its or any subsequent successors, Transferees and assigns.

            30. Assignments and Transfers by the Obligors

            Neither of the Obligors shall be entitled to assign or transfer all
or any of its rights, benefits and obligations hereunder.

            31. Assignments and Transfers by Banks

            31.1. Any Bank may, at any time, assign all or any of its rights and
benefits hereunder or transfer in accordance with Clause 31.3 all or any of its
rights, benefits and obligations hereunder Provided that (i) no such assignment
or transfer (other than to an affiliate of such Bank having its Facility Office
in a country in which another Bank has its Facility Office) may be made without
the prior written consent of the Borrower, such consent not to be unreasonably
withheld or delayed and to be deemed to have been given if a response to a
request for such consent is not received from the Borrower by such Bank within
fifteen business days of such request (incorporating such fifteen business days
deadline) being made, and (ii) no such transfer or assignment may be made if the
result thereof, at the time of such transfer or assignment or immediately
thereafter would be that either Obligor would be liable to pay an additional
amount or amounts pursuant to Clauses 11.1 or 13.1 which additional amount or
amounts would not have been payable had no such transfer or assignment occurred
unless the transferee or assignee accept responsibility to reimburse such
Obligor for any additional amount or amounts.

            31.2 If any Bank assigns all of any of its rights and benefits
hereunder in accordance with Clause 31.1, then, unless and until the assignee
has agreed with the Agent, the Arrangers and the other Banks that it shall be
under the same obligations towards each of them as it would have been under if
it had been an original party hereto as a Bank, the Agent, the Arrangers and the
other Banks shall not be obliged to recognise such assignee as having the rights
against each of them which it would have had if it had been such a party hereto.

            31.3 If any Bank wishes to transfer all or any of its rights,
benefits and/or obligations hereunder as contemplated in Clause 31.1, then such
transfer may be effected by the delivery to the Agent of a duly completed and
duly executed Transfer Certificate in which event, on the later of the Transfer
Date specified in such Transfer Certificate and the fifth business day after (or
such earlier business day endorsed by the Agent on such Transfer Certificate
falling on or after) the date of delivery of such Transfer Certificate to the
Agent:

            (i) to the extent that in such Transfer Certificate the Bank party
      thereto seeks to transfer its rights, benefits and obligations hereunder,
      each of the Obligors and such Bank shall be released from further
      obligations towards one another
<PAGE>
                                       48


      hereunder and their respective rights against one another shall be
      cancelled (such rights, benefits and obligations being referred to in this
      Clause 31.3 as "discharged rights and obligations");

            (ii) each of the Obligors and the Transferee party thereto shall
      assume obligations towards one another and/or acquire rights against one
      another which differ from such discharged rights and obligations only
      insofar as such Obligor and such Tranferee have assumed and/or acquired
      the same in place of such Obligor and such Bank; and

            (iii) the Agent, the Arrangers, such Transferee and the other Banks
      shall acquire the same rights and benefits and assume the same obligations
      between themselves as they would have acquired and assumed had such
      Transferee been an original party hereto as a Bank with the rights,
      benefits and/or obligations acquired or assumed by it as a result of such
      transfer.

            31.4 On the date upon which a transfer takes effect pursuant to
Clause 31.3, the Transferee in respect of such transfer shall pay to the Agent
for its own account a transfer fee of $800, payable under pre-advice, and
notwithstanding the provisions of Clause 31.3 such transfer shall not be
effective until such transfer fee is received by the Agent.

            32. Disclosure of Information

            Any Bank may disclose to any actual or potential assignee or
Transferee or to any person who may otherwise enter into contractual relations
with such Bank in relation to this Agreement such information about this
Agreement or the Obligors and the Group as such Bank shall consider appropriate.

                                 MISCELLANEOUS

            33. Calculations and Evidence of Debt

            33.1 Interest and commitment commission shall accrue from day to day
and shall be calculated on the basis of a year of 360 days (or, in the case of
any Advance denominated in sterling, 365 days or, in any case where market
practice differs, in accordance with market practice) and the actual number of
days elapsed.

            33.2 Any repayment of an Advance denominated in an Optional Currency
shall reduce the amount of such Advance by the amount of such Optional Currency
repaid and shall reduce the Dollar Amount of such Advance proportionately.

            33.3 If on any occasion a Reference Bank or Bank fails to supply the
Agent with a quotation required of it under the foregoing provisions of this
Agreement, the rate for which such quotation was required shall be determined
from those quotations which are supplied to the Agent.

            33.4 Each Bank shall maintain in accordance with its usual practice
accounts evidencing the amounts from time to time lent by and owing to it
hereunder.

            33.5 The Agent shall maintain on its books a control account or
accounts in which shall be recorded (i) the amount of any Advance made or
arising hereunder and each Bank's share therein, (ii) the amount of all
principal, interest and other sums due or to become due from either of the
Obligors to any of the Banks hereunder and each Bank's share therein and (iii)
the amount of any sum received or recovered by the Agent hereunder and each
Bank's share therein.

            33.6 In any legal action or proceeding arising out of or in
connection with this Agreement, the entries made in the accounts maintained
pursuant to Clauses 33.4 and 33.5 shall in the absence of mainfest error be
conclusive evidence of the existence and amounts of the obligations of the
Obligors therein recorded.

            33.7 A certificate of a Bank as to (i) the amount by which a sum
payable to it hereunder is to be increased under Clause 11.1 or (ii) the amount
for the time being required to indemnify it against any such cost, payment or
liability as is mentioned in Clause 11.2 or 13.1 shall, in the absence of
manifest error, be conclusive for the purposes of this Agreement.

            33.8 A certificate of the Agent as to the amount as any time due
from the Borrower hereunder or the amount which, but for any of the obligations
of the Borrower hereunder being or becoming void, voidable, unenforceable or
ineffective, at any time would have been due from the Borrower hereunder shall,
in the absence of manifest error, be conclusive for the purposes of Part 8.

            34. Remedies and Waivers

            No failure to exercise, nor any delay in exercising, on the part of
the Agent, the Arrangers and the Banks or any of them, any right or remedy
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise of any right or remedy prevent any further or other exercise thereof or
the exercise of any other right or remedy. The rights and remedies herein
provided are cumulative and not exclusive of any rights or remedies provided by
law.

            35. Partial Invalidity

            If, at any time, any provision hereof is or becomes illegal, invalid
or unenforceable in any respect under the law of any jurisdiction, neither the
legality, validity or enforceability of the remaining provisions hereof nor the
legality, validity or enforceability of such provision under the law of any
other jurisdiction shall in any way be affected or impaired thereby.

            36. Notices

            36.1 Each communication to be made hereunder shall be made in
writing but, unless otherwise stated, may be made by telex, telefax or letter
save that any Notice of Drawdown or other communication of instructions for
payment to be made by one person to another hereunder shall be made by telex or

            36.2 Any communication or document to be made or delivered by one

to which it is a party as Transferee) and shall be deemed to have been made or
delivered when despatched (and the appropriate answerback received) (in the case
of any communication made by telex) or (in the case of any communication made by
letter) when left at that address or (as the case may be) ten days after being
deposited in the post postage prepaid in an envelope addressed to it at that
address or (in the case of any communication of telefax) when actually received
Provided that any communication or document to be made or delivered to the Agent
shall be effective only when received by the Agent and then only if the same is
expressly marked for the attention of the department identified with the Agent's

                              LAW AND JURISDICTION

            37. Law

            This Agreement shall be governed by, and shall be construed in
accordance with, English law.

            38. Jurisdiction

            38.1 Each of the parties hereto irrevocably agrees for the benefit
of each of the Agent, the Arrangers and the Banks that the courts of England
shall have jurisdiction to hear and determine any suit, action or proceeding,
and to settle any disputes, which may arise out of or in connection with this
Agreement and, for such purposes, irrevocably submits to the jurisdiction of
such courts.

            38.2 Each of the Obligors irrevocably waives any objection which it
might now or hereafter have to the courts referred to in Clause 38.1 being
nominated as the forum to hear and determine any suit, action or proceeding, and
to settle any disputes, which may arise out of or in connection with this
Agreement and agrees not to claim that any such court is not a convenient or
appropriate forum.

            38.3 Each of the Obligors agrees that the process by which any suit,
action or proceeding is begun may be served on it by being delivered in England,
to Incentive Group Limited, c/o Munters Ltd, Blackstone Road, Huntingdon, Cambs
PE18 6EP, England or other its principal place of business for the time being.
If the appointment of the person mentioned in this Clause 38.3 ceases to be
effective in respect of either or both Obligors, such Obligor or Obligors shall
immediately appoint a further person in England to accept service of process on
its behalf in England and, failing such appointment within 15 days, the Agent
shall be entitled to appoint such a person by notice to such Obligor or
Obligors. Nothing contained herein shall affect the right to serve process in
any other manner permitted by law.

            38.4 The submission to the jurisdiction of the courts referred to in
Clause 38.1 shall not (and shall not be construed so as to) limit the right of
the Agent, the Arrangers and the Banks or any of them to take proceedings
against either of the Obligors in any other court of competent jurisdiction nor
shall the taking of proceedings in any one or more jurisdictions preclude the
taking of proceedings in any other jurisdiction (whether concurrently or not) if
and to the extent permitted by applicable law.

            38.5 Each of the Obligors hereby consents generally in respect of
any legal action or proceeding arising out of or in connection with this
Agreement to the giving of any relief or the issue of any process in connection
with such action or proceeding including, without limitation, the making,
enforcement or execution against any property whatsoever (irrespective of its
use or intended use) of any order or judgement which may be made or given in
such action or proceeding.

            38.6 To the extent that either of the Obligors may in any
jurisdiction claim for itself or its assets immunity from suit, execution,
attachment (whether in aid of execution, before judgement or otherwise) or other
legal process and to the extent that in any such jurisdiction there may be
attributed to itself or its assets such immunity (whether or not claimed), such
Obligor hereby irrevocably agrees 
<PAGE>
                                       52


not to claim and hereby irrevocably waives such immunity to the full extent
permitted by the laws of such jurisdiction.

            AS WITNESS the hands of the duly authorised representatives of the
parties hereto the day and year first before written.

                               THE FIFTH SCHEDULE

                             European Currency Unit

            1. For the purposes of this Agreement and subject to paragraph 2
below, "ECU" means the unit of account known as the ECU that is at present used
in the European Monetary System. Pursuant to Council Regulation (EEC) No.
1971/89 of 19 June, 1989 and No. 3320/94 of 22 December, 1994 the ECU is at
present valued on the basis of specified amounts of the currencies of the member
states of the European Union as shown below:

                                 0.6242  German Mark

                                0.08784  Pound Sterling-

                                  1.332  French Francs

                                  151.8  Italian Lire

                                 0.2198  Dutch Guilder

                                  3.301  Belgian Francs

                                  0.130  Luxembourg Franc

                                 0.1976  Danish Krone

                                   1.44  Greek Drachma

                               0.008552  Irish Pound

                                  6.885  Spanish Peseta

                                  1.393  Portuguese Escudo

            This basis may be changed by the European Union from time to time,
including changes in the components in which event the basis of valuation of the
ECU will change accordingly.

            2. If the Agent makes a declaration pursuant to Clause 22.2 then the
equivalent of the ECU in each of the component currencies as of any day (the
"Day of Valuation") shall be determined by the Agent as follows:

                  The components of the ECU for this purpose (the "Components")
            shall be the currency amounts that were components of the ECU when
            the ECU was most recently used in the European Monetary System*;
            provided, however, that, if the ECU is being used for the settlement
            of transactions by public institutions of or within the European
            Union or if it was so used after its most recent use in the European
            Monetary System, the Components shall be:

                        (i) the currency amounts that are components of the ECU
                  as so used as of the Day of Valuation; or

                        (ii) the currency amounts that were components of the
                  ECU when it was most recently so used*, as the case may be.

                  The equivalent of the ECU in a component currency thereof
            shall first be calculated as the sum of the dollar equivalents of
            the Components, and the equivalent of the ECU in such component
            currency shall then be calculated on the basis of the dollar
            equivalent of the ECU, 
<PAGE>
                                       60


            using the same rates as those used for determining the dollar
            equivalents of the Components as set forth below.

            Unless otherwise specified by the Agent, the dollar equivalent of
each of the Components shall be the arithmetic mean determined by the Agent on
the basis of the middle spot delivery quotations prevailing at 11.00 a.m. London
time in the London Foreign Exchange Market on the Day of Valuation, as obtained
by the Agent from the Reference Banks.**

            Unless otherwise specified by the Agent, in the event that there is
more than one market for dealing in any component currency by reason of foreign
exchange regulations or for any other reason, the market to be referred to in
respect of such currency shall be that upon which a non-resident issuer of
securities denominated in such currency would purchase such currency in order to
make payments in respect of such securities.

            * In the event that the official unit of any component currency of
            the ECU is altered by way of combination or subdivision, the number
            of units of that currency as a Component shall be divided or
            multiplied in the same proportion. In the event that two or more
            component currencies are consolidated into a single currency, the
            amounts of those currencies as Components shall be replaced by an
            amount in such single currency equal to the sum of the amounts of
            the consolidated component currencies expressed in such single
            currency. In the event that any component currency should be divided
            into two or more currencies, the amount of that currency as a
            Component shall be replaced by amounts of such two or more
            currencies each of which shall be equal in the amount of the former
            component currency divided by the number of currencies into which
            that currency was divided.

            ** In the event no such direct quotations are available for a
            component currency on a Day of Valuation from any of the Reference
            Banks because foreign exchange markets are closed in the country of
            issue of that currency or for any other reason, the most recent
            direct quotations of the Reference Banks for that currency obtained
            by the Agent shall be used in computing the equivalent of the ECU on
            such Day of Valuation, provided, however, that such most recent
            quotations may be used only if they were prevailing not more than
            two business days in the country of issue before such Day of
            Valuation. Beyond such period of two business days, the Agent shall
            determine the dollar equivalent of such Component on the basis of
            cross rates derived from middle spot delivery quotations for such
            component currency and for dollars prevailing at 11.00 a.m. London
            time on such Day of Valuation, as obtained by the Agent from two or
            more major banks, as selected by the Agent. Within such period of
            two business days, the Agent shall determine the dollar equivalent
            of such Component on the basis of such cross rates if the Agent
            judges that the equivalent so calculated is more representative than
            the dollar equivalent calculated on the basis of such most recent
            direct quotations.

            3. All determinations made by the Agent shall be at its sole
discretion and shall, in the absence of manifest error, be conclusive for all
purposes and binding upon the Borrower and the Guarantor.

                             Form of LC Notification

            From: Incentive Treasury AB and relevant Bank or Banks

            To:   Deutsche Bank Luxembourg S.A.

            Dear Sirs,

            1. We refer to the agreement (as from time to time amended, varied,
novated or supplemented, the "Facility Agreement") dated 24 May, 1995, and made
between Incentive Treasury AB as borrower, Incentive AB as guarantor, Deutsche
Bank Luxembourg S.A. and Enskilda, Skandinaviska Enskilda Banken as arrangers,
Deutsche Bank Luxembourg S.A. as agent and the financial institutions named

meaning in this notice.

            2. We hereby give you notice that we have entered into a LC

as follows:-

                  (i)   Currency and Amount of Letter of Credit...............

                  (ii)  Dollar Amount of Letter of Credit.....................

            Yours faithfully,


            for and on behalf of [Bank]           for and on behalf of Incentive
            or [Banks]                            Treasury AB

                              THE SEVENTH SCHEDULE

            Opinion of the Borrower's and Guarantor's Swedish Counsel

            To: Deutsche Bank Luxembourg S.A. as agent on its own behalf and for
and on behalf of the Arrangers and the Banks referred to in the Facility
Agreement mentioned below.

            Dear Sirs,

            1. We have acted on behalf of Incentive Treasury AB and Incentive AB
in connection with an agreement (the "Facility Agreement") date 24 May, 1995 and
made between Incentive Treasury AB as borrower, Incentive AB as guarantor,
Deutsche Bank Luxembourg S.A. and Enskilda, Skandinaviska Enskilda Banken as
arrangers, Deutsche Bank Luxembourg S.A. as agent and the financial institutions
defined therein as Banks.

            2. Terms defined in the Facility Agreement shall have the same
meaning herein.

            3. We have examined a signed copy of the Facility Agreement and such
other documents as we have considered it necessary or desirable to examine and,
on the assumption that the Facility Agreement is valid and legally binding under
English law (and subject as mentioned below), we are of the opinion that the
statements set out in Clause 15.1 (i) - (x) of the Facility Agreement are true
insofar as the same relate to the Obligors.

            4. This opinion is confined to matters of Swedish law and no opinion
is expressed as to the laws of any other jurisdiction.

            5. We have assumed the following:

            1. the Facility Agreement is within the capacity and power of and
has been validly authorized, executed and delivered by and is binding on the
parties thereto, other than the Obligors, which matters we have not
independently verified; and

            2. the genuineness of all signatures and the authenticity of all
documents submitted to us as originals and the conformity with the originals of
all documents submitted to us as copies thereof, and we have found nothing to
indicate that such assumptions are not fully justified.

            The qualifications to which this opinion is subject are as follows:

            1. The availability in Swedish courts of equitable remedies, such as
injunction and specific performance, is restricted under Swedish law.

            2. Swedish courts may award judgments expressed in foreign
currencies, but an enforcement in Sweden by the execution authorities of a
payment order in the judgement can generally only 
<PAGE>
                                       63


be performed in Swedish Kronor. Enforcement in Sweden of such judgments would,
if implemented in Swedish Kronor, be generally at the rate of exchange
prevailing at the date of enforcement rather than at the date of judgment.

            3. Nothing in this opinion must be taken as indicating that
obligations would be specifically enforceable and an enforcement of any
agreement or instrument may be limited by bankruptcy, insolvency, liquidation,
reorganization, limitation, and other laws of general application regarding or
affecting the rights of creditors.

            4. Pursuant to the Swedish Contract Act, a contract term may be
modified or set aside if it is adjudged to be unreasonable. Where any party to
an agreement is vested with a discretion or may determine a matter in its
opinion, Swedish law may require that such discretion is exercised reasonably or
that such opinion is based on reasonable grounds and a provision that a certain
determination is conclusive and binding will not prevent judicial enquiry into
the merits of any claim by an aggrieved party.

            5. A Swedish court may reject the right to take proceedings in
Sweden if proceedings which have or may lead to a judgment which is enforceable
in Sweden have already been taken in another court of competent jurisdiction
within or outside Sweden.

            6. In giving the foregoing opinion, we have relied as to certain
factual matters upon certificates of officers of the Obligors and of public
officials.

            7. This opinion is confined to and is given on the basis of Swedish
law as it exists at the date hereof. We have made no investigations of the laws
of England as a basis for this opinion and do not express or imply any opinion
thereon.

            8. This opinion is strictly limited to the matters stated herein and
is not to be read as extending by implication to any other matters in connection
with the Facility Agreement referred to herein or the transactions contemplated
by such agreement.

            This opinion is addressed to you and, without our express consent,
is not to be transmitted to any other person, nor is it to be relied upon by any
other person or for any purpose.


            Yours faithfully,

                               THE EIGHTH SCHEDULE

                      Opinion of the Banks' Swedish Counsel

To:   the Arrangers and the Banks
      (each as defined in the Facility
      Agreement referred to below)

      and

      Deutsche Bank Luxembourg S. A.
      as Agent

                                                           Stockholm, [  ], 1995

Dear Sirs,

      Re: US $ 500,000,000 Multicurrency Revolving Credit Facility dated 24 May,
      1995, (the "Facility Agreement") for Incentive Treasury AB as Borrower and
      guaranteed by Incentive AB as Guarantor

            1. We have acted as your legal advisers in Sweden in connection with
the Facility Agreement made between the Borrower, the Guarantor, the Arrangers,
the banks and other financial institutions listed on the signature pages of the
Facility Agreement as lenders participating in the Revolving Credit Facility and
the Agent.

            2. For the purposes of this opinion, we have examined and relied
upon:

            (a) a conformed copy of the Facility Agreement;

            (b) a copy of each of the Borrower's and the Guarantor's articles of
      association;

            (c) a copy of the registration certificate of the Borrower issued by
      the Parent and Registration Office on [    ];

            (d) a copy of the registration certificate of the Guarantor issued
      by the Patent and Registration Office on [    ];

            (e) a copy of a Board Resolution of the Borrower passed at a meeting
      of its board of directors on [    ] approving the entering into the
      Facility Agreement;

            (f) a copy of a board resolution of the Guarantor passed at a
      meeting of its board of directors held on [    ] approving the giving of
      its guarantee under the Facility Agreement;
<PAGE>
                                       65


            (g) a copy of the power of attorney dated [    ], 1995 authorizing
      Mr. [    ] and Mr. [    ] jointly to sign the Facility Agreement on behalf
      of the Borrower; and

            (h) a copy of the power of attorney dated [    ], 1995 authorizing
      Mr. [    ] and Mr. [    ] jointly to sign the Facility Agreement on behalf
      of the Guarantor.

            3. We have assumed the following:

            (A) the Facility Agreement is within the capacity and power of and
      has been validly authorized, executed and delivered by and is binding on
      the parties thereto, other than the Borrower and the Guarantor, which
      matters we have not independently verified;

            (B) the Facility Agreement and the rights and obligations created
      thereby are valid and legally binding under the laws of England, by which
      they are expressed to be governed; and

            (C) the genuineness of all signatures and the authenticity of all
      documents submitted to us as originals and the conformity with the
      originals of all documents submitted to us as copies thereof;

and we have found nothing to indicate that such assumptions are not fully
justified.

            Terms defined in the Facility Agreement shall, when used in this
opinion, have the same meanings herein as therein unless otherwise defined.

            4. Based on the foregoing, we are of the opinion that, so far as the
laws of Sweden are concerned that the statements set out in Clause 15.1 of the
Facility Agreement are true and correct as far as they relate to each Obligor
respectively.

            5. the qualifications to which this opinion is subject are as
follows:

            (1) The availability in Swedish courts of equitable remedies, such
      as injunction and specific performance, is restricted under Swedish law.

            (2) Swedish courts may award judgments expressed in foreign
      currencies (including $, sterling and ECU), but an enforcement in Sweden
      by the execution authorities of a payment order in the judgment can
      generally only be performed in Swedish kronor ("SEK"). Enforcement in
      Sweden of such judgments would, if implemented in SEK, be generally at the
      rate of exchange ruling at the date of enforcement rather than at the date
      of judgment.

            (3) Nothing in this opinion must be taken as indicating that
      obligations would be specifically enforceable and an enforcement of any
      agreement or instrument may be limited by bankruptcy, insolvency,
      liquidation, reorganisation, limitation, and other laws of general
      application regarding or affecting the rights of creditors.

            (4) Pursuant to the Swedish Contract Act, a contract term may be
      modified or set aside if it is adjudged to be unreasonable. Where any
      party to an agreement is vested with a 
<PAGE>
                                       66


      discretion or may determine a matter in its opinion, Swedish law may
      require that such discretion is exercised reasonably or that such opinion
      is based on reasonable grounds and a provision that a certain
      determination is conclusive and binding will not prevent judicial enquiry
      into the merits of any claim by an aggrieved party. Although the Facility
      Agreement is subject to English law, we cannot express any opinion whether
      a Swedish court would find such equitable rules of the Swedish Contracts
      Act applicable either directly or by reason of Swedish public policy.
      However, in our opinion, having regard to all the relevant circumstances,
      even if such rules of the Swedish Contracts Act did apply, neither the
      Facility Agreement nor the terms thereof would be subject to modification
      or being set aside pursuant to such rules.

            (5) A Swedish court may reject the right to take proceedings in
      Sweden if proceedings which have or may lead to a judgment which is
      enforceable in Sweden have already been taken in another court of
      competent jurisdiction within or outside Sweden.

            (6) In giving the foregoing opinion, we have relied as to certain
      factual matters upon certificates by officers of the Borrower, the
      Guarantor and by public officials.

            (7) This opinion is confined to and is given on the basis of Swedish
      law as it exists at the date hereof. We have made no investigations of the

                               THE NINTH SCHEDULE

                              Associated Costs Rate

            1. For the purposes of this Agreement, the cost of compliance with
existing requirements of the Bank of England in respect of Advances denominated
in sterling will be calculated by the Agent in relation to each Advance on the
basis of rates to be supplied by each of the Reference Banks by reference to the
circumstances existing on the first day of the Term in respect of such Advance
and, if such Term exceeds three months, at three calendar monthly intervals from
the first day of such Term during its duration in accordance with the following
formula:

            AB + C(B - E) + D(B - F)      per cent. per annum
            ------------------------
                 100 - (A + D)

Where:

      A     is the percentage of eligible liabilities which such Reference Bank
            is from time to time required to maintain as an interest free cash
            deposit with the Bank of England to comply with cash ratio
            requirements;

      B     is the percentage rate per annum at which sterling deposits are
            offered by such Reference Bank in accordance with its normal
            practice, for a period equal to (i) the Term (or, as the case may
            be, remainder of such Term) in respect of the relevant Advance or
            (ii) three months, whichever is the shorter, to a leading bank in
            the London Interbank Market at or about 11.00 a.m. in a sum
            approximately equal to the amount of such Advance.

      C     is the percentage of eligible liabilities which such Reference Bank
            is from time to time required by the Bank of England to maintain as
            secured money with members of the London Discount Market Association
            ("LDMA") and/or as secured call money with money brokers and gilt
            edged market makers.

      D     is the percentage of eligible liabilities which such Reference Bank
            is required from time to time to maintain as interest bearing
            special deposits with the Bank of England.

      E     is the percentage rate per annum at which members of the LDMA are
            offered sterling deposits in a sum approximately equal to the amount
            of the relevant Advance as a callable fixture from such Reference
            Bank for such period as determined in accordance with B above at or
            about 11.00 a.m.

      F     is the percentage rate per annum payable by the Bank of England to
            such Reference Bank on interest bearing special deposits.

            2. For the purposes of this Schedule "eligible liabilities" and
"special deposits" shall bear the meanings ascribed to them from time to time by
the Bank of England.

            3. The percentages used in A, C and D above shall be those required
to be maintained on the first day of the relevant period as determined in
accordance with B above.
<PAGE>
                                       68


            4. In application of the above formula, A, B, C, D, E and F will be
included in the formula as figures and not as percentages e.g. if A is 0.5 per
cent. and B is 12 per cent., AB will be calculated as 0.5 x 12 and not as 0.5
per cent. x 12 per cent.

            5. Calculations will be made on the basis of a 365 day year (or, if
market practice differs, in accordance with market practice).

            6. A negative result obtained by subtracting E from B or F from B
shall be taken as zero.

            7. The arithmetic mean of the resulting figures for each Reference
Bank shall be calculated and shall then be rounded upwards, if not already such
a multiple, to the nearest whole multiple of one-thirty-second of one per cent.
per annum.

            8. Additional amounts calculated in accordance with this Schedule
are payable on the last day of the Term to which they relate.

            9. The determination of the Associated Costs Rate in relation to any
period shall, in the absence of manifest error, be conclusive and binding on all
of the parties hereto.

            10. The Agent may from time to time, after consultation with the
Borrower and the Banks, determine and notify to all the parties hereto any
amendments or variations which are required to be made to the formula set out
above in order to comply with any requirements from time to time imposed by the
Bank of England in relation to Advances denominated in sterling (including
without limitation, any requirements relating to sterling primary liquidity)
and, any such determination shall, in the absence of manifest error, be
conclusive and binding on all the parties hereto.

                        The Commitment Fee will be calculated on the basis of

                        evidencing the payment of such taxes or deductions) in
                        such a way that the Borrower shall pay such additional
                        amounts as will result in the immediate receipt by the
                        Lender of a net amount that is equal to the full amount

2.    As of October 29, 1996 the Commitment Fee shall be reduced from 0.04% per

          AGREEMENT AND PLAN OF MERGER, dated as of May 5,1997  (this
"AGREEMENT"), among INCENTIVE AB, a corporation organized under the laws of
Sweden ("PARENT"), HH ACQUISITION CORP., a Delaware corporation and an indirect
wholly owned subsidiary of Parent ("PURCHASER"), and VIVRA INCORPORATED, a
Delaware corporation (the "COMPANY").

          WHEREAS, the Boards of Directors of Parent, Purchaser and the Company
have each determined that it is in the best interests of their respective
stockholders for Parent to acquire the Company upon the terms and subject to the
conditions set forth herein; 

          WHEREAS, in furtherance of such acquisition, it is proposed that
Purchaser shall make a cash tender offer (the "OFFER") to acquire all of the
issued and outstanding shares of Common Stock, par value $0.01 per share, of the
Company ("COMPANY COMMON STOCK") (such shares of Company Common Stock being
hereinafter collectively referred to herein as "SHARES") for $35.62 per Share
(such amount, or any greater amount per Share paid pursuant to the Offer, being
hereinafter referred to as the "PER SHARE AMOUNT") net to the seller in cash,
upon the terms and subject to the conditions of this Agreement and the Offer;

          WHEREAS, the Board of Directors of the Company (the "BOARD") has
unanimously consented to the making of the Offer by Purchaser and resolved and
agreed to recommend that holders of Shares tender their Shares pursuant to the
Offer; 

          WHEREAS, also in furtherance of such acquisition, the Boards of
Directors of Parent, Purchaser and the Company have each approved the merger
(the "MERGER") of Purchaser with and into the Company in accordance with the
General Corporation Law of the State of Delaware ("DELAWARE LAW") following the
consummation of the Offer and upon the terms and subject to the conditions set
forth herein; and

          WHEREAS, as an inducement to Parent to enter this Agreement, the
Company has entered into an Agreement and Plan of Reorganization in the form
attached hereto as Exhibit I (the "SPECIALTY MERGER AGREEMENT") pursuant to
which the Company has agreed that VSP Acquisition, Inc., a Delaware corporation
and a wholly owned subsidiary of VSP Holdings, Inc., a Delaware corporation,
shall merge with and into Vivra Specialty Partners, Inc., a Nevada corporation
and a majority-owned subsidiary of the Company ("SPECIALTY PARTNERS") (the
"SPECIALTY MERGER TRANSACTION"). 
          
          NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements herein contained, and intending to be legally bound
hereby, Parent, Purchaser and the Company hereby agree as follows:


<PAGE>


                                      ARTICLE I

                                      THE OFFER

          SECTION 1.01.  THE OFFER.  (a)  Provided that this Agreement shall not
have been terminated in accordance with Section 8.01 and none of the events set
forth in Annex A hereto shall have occurred or be existing, Purchaser shall
commence the Offer as promptly as reasonably practicable after the date hereof,
but in no event later than five business days after the initial public
announcement of Purchaser's intention to commence the Offer.  The obligation of
Purchaser to accept for payment and pay for Shares tendered pursuant to the
Offer shall be subject to the condition (the "MINIMUM CONDITION") that at least
the number of Shares that when added to the Shares already owned by Parent and
its affiliates shall constitute a majority of the then outstanding Shares on a
fully diluted basis (including, without limitation, all Shares issuable upon the
conversion of any outstanding convertible securities or upon the exercise of any
outstanding options, warrants or rights (other than the Company Rights (as
defined in Section 3.03))) shall have been validly tendered and not withdrawn
prior to the expiration of the Offer and also shall be subject to the
satisfaction of the other conditions set forth in Annex A hereto.  Purchaser
expressly reserves the right to waive any such condition, to increase the price
per Share payable in the Offer, and to make any other changes in the terms and
conditions of the Offer; PROVIDED, HOWEVER, that no change may be made which
decreases the price per Share payable in the Offer or which reduces the maximum
number of Shares to be purchased in the Offer or which imposes conditions to the
Offer other than those set forth in Annex A hereto.  Notwithstanding the
foregoing, Purchaser may, without the consent of the Company, (i) extend the
Offer beyond the scheduled expiration date (the initial scheduled expiration
date being 20 business days following the commencement of the Offer) if, at the
scheduled expiration date of the Offer, any of the conditions to Purchaser's
obligation to accept for payment, and to pay for, the Shares, shall not be
satisfied or waived, (ii) extend the Offer for any period required by any rule,
regulation or interpretation of the Securities and Exchange Commission (the
"SEC") or the staff thereof applicable to the Offer, or (iii) extend the Offer
for an aggregate period of not more than 10 business days beyond the latest
applicable date that would otherwise be permitted under clause (i) or (ii) of
this sentence, if as of such date, all of the conditions to Purchaser's
obligations to accept for payment, and to pay for, the Shares are satisfied or
waived, but the number of Shares validly tendered and not withdrawn pursuant to
the Offer equals 80 percent or more, but less than 90 percent, of the
outstanding Shares on a fully diluted basis; PROVIDED, HOWEVER, that (A) if, on
the initial scheduled expiration date of the Offer, the sole condition remaining
unsatisfied is (1) the failure of the waiting period under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR ACT"), to have expired
or been terminated or (2) the failure to consummate the Specialty Merger
Transaction and such transaction has not been consummated solely due to the
failure of the waiting period under the HSR Act to have expired or been
terminated, then, in either case, Purchaser shall extend the Offer from time to
time until five business days after the


                                          2

<PAGE>


expiration or termination of the applicable waiting period under the HSR Act and
(B) if the sole condition remaining unsatisfied on the initial scheduled
expiration date of the Offer is the condition set forth in (f) of Annex A, the
Purchaser shall, so long as the breach can be cured and the Company is
vigorously attempting to cure such breach, extend the Offer from time to time
until five business days after such breach is cured (provided that Purchaser
shall not be required to extend the Offer beyond 35 days after such initial
scheduled expiration date).  The Per Share Amount shall, subject to applicable
withholding of taxes, be net to the seller in cash, upon the terms and subject
to the conditions of the Offer.  Subject to the terms and conditions of the
Offer, Purchaser shall, promptly after expiration of the Offer, pay for all
Shares validly tendered and not withdrawn.

          (b)  As soon as practicable on the date of commencement of the Offer,
Purchaser shall file with the SEC a Tender Offer Statement on Schedule 14D-1
(together with all amendments and supplements thereto, the "SCHEDULE 14D-1")
with respect to the Offer.  The Schedule 14D-1 shall contain or shall
incorporate by reference an offer to purchase (the "OFFER TO PURCHASE") and
forms of the related letter of transmittal and any related summary advertisement
(the Schedule 14D-1, the Offer to Purchase and such other documents, together
with all supplements and amendments thereto, being referred to herein
collectively as the "OFFER DOCUMENTS").  Parent, Purchaser and the Company agree
to correct promptly any information provided by any of them for use in the Offer
Documents which shall have become false or misleading, and Parent and Purchaser
further agree to take all steps necessary to cause the Schedule 14D-1 as so
corrected to be filed with the SEC and the other Offer Documents as so corrected
to be disseminated to holders of Shares, in each case as and to the extent
required by applicable federal securities laws.

          SECTION 1.02.  COMPANY ACTION.  (a)  The Company hereby consents to
the Offer and represents that (i) the Board, at a meeting duly called and held
on May 4, 1997, has unanimously (A) determined that this Agreement and the
transactions contemplated hereby, including each of the Offer and the Merger,
are in the best interests of the holders of Shares, (B) approved and adopted
this Agreement and the transactions contemplated hereby and (C) resolved to
recommend that the stockholders of the Company accept the Offer and approve and
adopt this Agreement and the transactions contemplated hereby, and (ii) Goldman,
Sachs & Co. ("GOLDMAN SACHS") has delivered to the Board its opinion that the
consideration to be received by the holders of Shares pursuant to each of the
Offer and the Merger is fair to the holders of Shares.   The Company hereby
consents to the inclusion in the Offer Documents of the recommendation of the
Board described in the immediately preceding sentence.  The Company has been
advised by each of its directors and executive officers that they intend to
tender all Shares beneficially owned by them to Purchaser pursuant to the Offer.

          (b)  As soon as reasonably practicable on the date of commencement of
the Offer, the Company shall file with the SEC a Solicitation/Recommendation
Statement on


                                          3

<PAGE>


Schedule 14D-9 (together with all amendments and supplements thereto, the
"SCHEDULE 14D-9") containing the recommendation of the Board described in
Section 1.02(a), except if the Board determines in good faith that an
alternative recommendation to be necessary in accordance with its fiduciary
duties to the Company's stockholders under applicable law as advised by outside
legal counsel, and shall disseminate the Schedule 14D-9 to the extent required
by Rule 14d-9 promulgated under the Securities Exchange Act of 1934, as amended
(the "EXCHANGE ACT"), and any other applicable federal securities laws.  The
Company, Parent and Purchaser each agree to correct promptly any information
provided by any of them for use in the Schedule 14D-9 which shall have become
false or misleading, and the Company further agrees to take all steps necessary
to cause the Schedule 14D-9 as so corrected to be filed with the SEC and
disseminated to holders of Shares, in each case as and to the extent required by
applicable federal securities laws.

          (c)  The Company shall promptly furnish Purchaser with mailing labels
containing the names and addresses of all record holders of Shares and with
security position listings of Shares held in stock depositories, each as of a
recent date, together with all other available listings and computer files
containing names, addresses and security position listings of record holders and
beneficial owners of Shares.  The Company shall furnish Purchaser with such
additional information, including, without limitation, updated listings and
computer files of stockholders, mailing labels and security position listings,
and such other assistance as Parent, Purchaser or their agents may reasonably
request.  Subject to the requirements of applicable law, and except for such
steps as are necessary to disseminate the Offer Documents and any other
documents necessary to consummate the Offer or the Merger, Parent and Purchaser
shall hold in confidence the information contained in such labels, listings and
files, shall use such information solely in connection with the Offer and the
Merger, and, if this Agreement shall be terminated in accordance with
Section 8.01 or if the Offer is otherwise terminated, shall promptly deliver to
the Company all copies of such information and any information derived therefrom
then in their possession or the possession of their agents and representatives.


                                      ARTICLE II

                                      THE MERGER

          SECTION 2.01.  THE MERGER.  Upon the terms and subject to the
conditions set forth in Article VII, and in accordance with Delaware Law, at the
Effective Time (as hereinafter defined) Purchaser shall be merged with and into
the Company.  As a result of the Merger, the separate corporate existence of
Purchaser shall cease and the Company shall continue as the surviving
corporation of the Merger (the "SURVIVING CORPORATION").

          SECTION 2.02.  EFFECTIVE TIME.  As promptly as practicable after the
satisfaction or, if permissible, waiver of the conditions set forth in

merger (in any of such cases, the "CERTIFICATE OF MERGER") with the Secretary of
State of the State of Delaware, in such form as is required by, and executed in
accordance with the relevant provisions of, Delaware Law (the date and time of

Effective Time the Certificate of Incorporation of Purchaser, as in effect

Effective Time, Article I of the Certificate of Incorporation of the Surviving
Corporation shall be amended to read as follows:  "The name of the corporation
is Vivra Incorporated."

          (b)  The By-laws of Purchaser, as in effect immediately prior to the
Effective Time, shall be the By-laws of the Surviving Corporation until
thereafter amended as provided by law, the Certificate of Incorporation of the
Surviving Corporation and such By-laws.

          SECTION 2.05.  DIRECTORS AND OFFICERS.  The directors of Purchaser
immediately prior to the Effective Time shall be the initial directors of the
Surviving Corporation, each to hold office in accordance with the Certificate of

initial officers of the Surviving Corporation, in each case until their
respective successors are duly elected or appointed and qualified in accordance
with the Certificate of Incorporation and By-laws of the Surviving Corporation
and Delaware Law.

          SECTION 2.06.  CONVERSION OF SECURITIES.  At the Effective Time, by
virtue of the Merger and without any action on the part of Purchaser, the
Company or the holders of any of the following securities:

               (a)  Each Share issued and outstanding immediately prior to the
     Effective Time (other than any Shares to be cancelled pursuant to
     Section 2.06(b) and any Dissenting Shares (as hereinafter defined)) shall
     be cancelled and shall be converted automatically into the right to receive
     an amount equal to the Per Share Amount in cash (the "MERGER
     CONSIDERATION") payable, without interest, to the holder


                                          5

<PAGE>


     of such Share, upon surrender, in the manner provided in Section 2.09, of
     the certificate that formerly evidenced such Share;

               (b)  Each Share held in the treasury of the Company and each
     Share owned by Purchaser, Parent or any direct or indirect wholly owned
     subsidiary of Parent or of the Company immediately prior to the Effective
     Time shall be cancelled without any conversion thereof and no payment or
     distribution shall be made with respect thereto; and

               (c)  Each share of Common Stock, par value $0.01 per share, of
     Purchaser issued and outstanding immediately prior to the Effective Time
     shall be converted into and exchanged for one validly issued, fully paid
     and nonassessable share of Common Stock, par value $0.01 per share, of the
     Surviving Corporation.

          SECTION 2.07.  EMPLOYEE STOCK OPTIONS.  All outstanding Employee Stock
Options (as defined in Section 6.06(a)) will be cancelled immediately prior to
the Effective Time and, in consideration of such cancellation, the Surviving
Corporation will pay each holder of an Employee Stock Option the cash amount
determined in accordance with Section 6.06(a).  All restricted stock under the
Company's 1989 Stock Incentive Plan will be vested, and any restrictions
attached thereto pursuant to such plan will lapse, immediately prior to the
Effective Time.

          SECTION 2.08.  DISSENTING SHARES.  (a)  Notwithstanding any provision
of this Agreement to the contrary, Shares that are outstanding immediately prior
to the Effective Time and which are held by stockholders who shall have not
voted in favor of the Merger or consented thereto in writing and who shall have
demanded properly in writing appraisal for such Shares in accordance with
Section 262 of Delaware Law (collectively, the "DISSENTING SHARES") shall not be
converted into or represent the right to receive the Merger Consideration.  Such
stockholders shall be entitled to receive payment of the appraised value of such
Shares held by them in accordance with the provisions of such Section 262,
except that all Dissenting Shares held by stockholders who shall have failed to
perfect or who effectively shall have withdrawn or lost their rights to
appraisal of such Shares under such Section 262 shall thereupon be deemed to
have been converted into and to have become exchangeable for, as of the
Effective Time, the right to receive the Merger Consideration, without any
interest thereon, upon surrender, in the manner provided in Section 2.09, of the
certificate or certificates that formerly evidenced such Shares.

          (b)  The Company shall give Parent (i) prompt notice of any demands
for appraisal received by the Company, withdrawals of such demands, and any
other instruments served pursuant to Delaware Law and received by the Company
and (ii) the opportunity to direct all negotiations and proceedings with respect
to demands for appraisal under Delaware Law.  The Company shall not, except with
the prior written consent of Parent, make any



                                          6

<PAGE>


payment with respect to any demands for appraisal or offer to settle or settle
any such demands.

          SECTION 2.09.  SURRENDER OF SHARES; STOCK TRANSFER BOOKS.  (a)  Prior
to the Effective Time, Purchaser shall designate a bank or trust company to act
as agent (the "PAYING AGENT") for the holders of Shares in connection with the
Merger to receive the funds to which holders of Shares shall become entitled
pursuant to Section 2.06(a).  Such funds shall be invested by the Paying Agent
as directed by the Surviving Corporation.

          (b)  Promptly after the Effective Time, the Surviving Corporation
shall cause to be mailed to each person who was, at the Effective Time, a holder
of record of Shares entitled to receive the Merger Consideration pursuant to
Section 2.06(a)(i) a form of letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the certificates
evidencing such Shares (the "CERTIFICATES") shall pass, only upon proper
delivery of the Certificates to the Paying Agent) and (ii) instructions for use
in effecting the surrender of the Certificates pursuant to such letter of
transmittal.  Upon surrender to the Paying Agent of a Certificate, together with
such letter of transmittal, duly completed and validly executed in accordance
with the instructions thereto, and such other documents as reasonably may be
required pursuant to such instructions, the holder of such Certificate shall be
entitled to receive in exchange therefor the Merger Consideration for each Share
formerly evidenced by such Certificate, and such Certificate shall then be
cancelled.  No interest shall accrue or be paid on the Merger Consideration
payable upon the surrender of any Certificate for the benefit of the holder of
such Certificate.  If payment of the Merger Consideration is to be made to a
person other than the person in whose name the surrendered Certificate is
registered on the stock transfer books of the Company, it shall be a condition
of payment that the Certificate so surrendered shall be endorsed properly or
otherwise be in proper form for transfer and that the person requesting such
payment shall have paid all transfer and other taxes required by reason of the
payment of the Merger Consideration to a person other than the registered holder
of the Certificate surrendered or shall have established to the satisfaction of
the Surviving Corporation that such taxes either have been paid or are not
applicable.

          (c)  At any time following the sixth month after the Effective Time,
the Surviving Corporation shall be entitled to require the Paying Agent to
deliver to it any funds which had been made available to the Paying Agent and
not disbursed to holders of Shares (including, without limitation, all interest
and other income received by the Paying Agent in respect of all funds made
available to it), and thereafter such holders shall be entitled to look to the
Surviving Corporation (subject to abandoned property, escheat and other similar
laws) only as general creditors thereof with respect to any Merger Consideration
that may be payable upon due surrender of the Certificates held by them. 
Notwithstanding the foregoing, neither the Surviving Corporation nor the Paying
Agent shall be liable to any holder of a


                                          7

<PAGE>


Share for any Merger Consideration delivered in respect of such Share to a
public official pursuant to any abandoned property, escheat or other similar
law.

          (d)  At the close of business on the day of the Effective Time, the
stock transfer books of the Company shall be closed and thereafter there shall
be no further registration of transfers of Shares on the records of the
Company. From and after the Effective Time, the holders of Shares outstanding
immediately prior to the Effective Time shall cease to have any rights with
respect to such Shares except as otherwise provided herein or by applicable law.

          SECTION 2.10.  CONVERTIBLE SUBORDINATED NOTES.   (a)  Prior to the
Effective Time, the Company shall, in accordance with the terms of the indenture
dated as of July 8, 1996 (the "INDENTURE") between the Company and State Street
Bank and Trust Company, as trustee (the "TRUSTEE"), execute and deliver to the
Trustee a supplemental indenture (which shall conform to the Trust Indenture Act
of 1939, as amended, as in force at the date of execution of such supplemental
indenture) providing that from and after the Effective Time, by virtue of the
Merger and without any further action on the part of the Company, each $1,000
principal amount of the Company's 5% Convertible Subordinated Notes Due 2001
(the "5% NOTES") shall be convertible into an amount of cash equal to the Per
Share Amount multiplied by 26.88.  The Company shall promptly cause notice of
the execution and delivery of such supplemental indenture to be mailed to each
holder of the 5% Notes in accordance with the Indenture and shall take such
other actions as may be appropriate or required by the Indenture, or otherwise,
to implement the terms of the Indenture, as supplemented as provided herein.

          (b)  The Company agrees that it shall offer to repurchase the Notes at
the option of the holders thereof and shall consummate such repurchase, in each
case in accordance with the terms and conditions of Section 3.8 through Section
3.13, inclusive, of the Indenture.


                                     ARTICLE III

                    REPRESENTATIONS AND WARRANTIES OF THE COMPANY

          Except as set forth in the disclosure schedule delivered by the
Company to Parent concurrently with the execution of this Agreement (the
"COMPANY DISCLOSURE SCHEDULE"), which shall identify exceptions by specific
Section references, the Company hereby represents and warrants to Parent and
Purchaser that:

          SECTION 3.01.  ORGANIZATION AND QUALIFICATION; SUBSIDIARIES.  Each of
the Company and each subsidiary of the Company (a "SUBSIDIARY") is a corporation
duly


                                          8

<PAGE>


incorporated, validly existing and in good standing under the laws of the
jurisdiction of its incorporation and has the requisite power and authority and
all necessary governmental approvals to own, lease and operate its properties
and to carry on its business as it is now being conducted, except where the
failure to be so organized, existing or in good standing or to have such power,
authority and governmental approvals would not prevent or materially delay
consummation of the Merger or the other Transactions, or otherwise prevent the
Company from performing its material obligations under this Agreement, and would
not, individually or in the aggregate, have a Material Adverse Effect (as
defined below).  The Company and each Subsidiary is duly qualified or licensed
as a foreign corporation to do business, and is in good standing, in each
jurisdiction where the character of the properties owned, leased or operated by
it or the nature of its business makes such qualification or licensing
necessary, except for such failures to be so qualified or licensed and in good
standing that would not prevent or materially delay consummation of the Merger
or the other Transactions, or otherwise prevent the Company from performing its
material obligations under this Agreement, and would not, individually or in the
aggregate, have a Material Adverse Effect.  When used in connection with the
Company or any Subsidiary, the term "MATERIAL ADVERSE EFFECT" means any
circumstance, change in or effect on the Company, any Subsidiary or any
circumstance, change in or effect on the Company's dialysis, renal care,
nephrology disease management, or nephrologist practice management business or
the Company's business of contracting with payors on behalf of nephrologists
(collectively, the "DIALYSIS BUSINESS") that is, or is reasonably likely to be,
materially adverse to the value of the Dialysis Business or the Company and the
Dialysis Subsidiaries (not including the Specialty Business (as defined below)),
taken as a whole, other than a change, condition, event or development that
results from (i) the announcement of the Transactions, (ii) general economic
conditions, (iii) conditions that are generally applicable to the dialysis
business, the renal care business or the nephrologist practice management
business, or (iv) actions, legislation or initiatives that are generally
applicable to the dialysis business, the renal care business or the nephrologist
practice management business, or any proposals thereof, of any Governmental
Authority or any announcement thereof.  Section 3.01 of the Company Disclosure
Schedule sets forth, as of the date of this Agreement, a true and complete list
of all of the Subsidiaries (which list indicates those Subsidiaries (the
"DIALYSIS SUBSIDIARIES") that are engaged in the Dialysis Business and those
Subsidiaries (the "SPECIALTY SUBSIDIARIES") that are engaged, in whole or in
part, in the business of providing specialty physician network and disease
management services to managed care and provider organizations, other than such
businesses included in the Dialysis Business (collectively, the "SPECIALTY
BUSINESS")), together with the jurisdiction of incorporation of each Subsidiary
and the percentage of each Subsidiary's outstanding capital stock or other
equity interests owned by the Company and Subsidiaries, as the case may be. 
There are no partnerships or joint venture arrangements or other business
entities in which the Company or any Subsidiary owns an equity interest.  The
Dialysis Business is conducted through the Company and the Dialysis
Subsidiaries, and all the assets and services predominantly used in the Dialysis
Business as presently conducted are owned or leased by the Company and the
Dialysis


                                          9

Subsidiaries.  Neither Specialty Partners nor any Specialty Subsidiary is
engaged, in any material respect, in the Dialysis Business.

          SECTION 3.02.  CERTIFICATE OF INCORPORATION AND BY-LAWS.  The Company
has heretofore made available to Parent a complete and correct copy of the
Certificate of Incorporation and the By-laws (or equivalent organizational
documents), each as amended to date, of the Company and each Subsidiary.  Such
Certificates of Incorporation, By-laws or equivalent organizational documents
are in full force and effect.  The Company and each Subsidiary are not in
violation of any of the provisions of their respective Certificates of
Incorporation or By-laws (or equivalent organizational documents).

          SECTION 3.03.  CAPITALIZATION.  The authorized capital stock of the
Company consists of 80,000,000 Shares and 10,000,000 shares of Preferred Stock,
par value $.01 per share ("COMPANY PREFERRED STOCK").  As of the date hereof,
(i) 41,991,547 Shares are issued and outstanding, all of which are validly
issued, fully paid and nonassessable, (ii) no Shares are held in the treasury of
the Company, (iii) no Shares are held by the Subsidiaries, (iv) 2,711,133 Shares
are reserved for future issuance pursuant to employee stock options (the
"COMPANY OPTIONS") granted under the Company's Revised 1989 Stock Incentive
Plan, 1989 Transition Consultants' Stock Option Plan or any other plan or
arrangement of the Company (collectively, the "COMPANY STOCK OPTION PLANS"), and
(v) 4,261,963 Shares are reserved for issuance pursuant to the conversion of the
5% Notes.  As of the date hereof, no shares of Company Preferred Stock are
issued and outstanding.  Except for (i) Company Options granted pursuant to the
Company Stock Option Plans or options or restricted stock to be granted pursuant
to automatic grants under Company Stock Option Plans, (ii) options granted
pursuant to Subsidiary stock option plans described in Section 3.03 of the
Disclosure Schedule, (iii) the 5% Notes and (iv) the rights (the "COMPANY
RIGHTS") issued pursuant to the Amended and Restated Rights Agreement, dated as
of February 13, 1996 (the "RIGHTS AGREEMENT"), between the Company and The First
National Bank of Boston, as Rights Agent, there are no options, warrants or
other rights, agreements, arrangements or commitments of any character relating
to the issued or unissued capital stock of the Company or any Dialysis
Subsidiary or obligating the Company or any Dialysis Subsidiary to issue or sell
any shares of capital stock of, or other equity interests in, the Company or any
Dialysis Subsidiary.  All Shares subject to issuance as aforesaid, upon issuance
on the terms and conditions specified in the instruments pursuant to which they
are issuable, will be duly authorized, validly issued, fully paid and
nonassessable.  There are no outstanding contractual obligations of the Company
or any Dialysis Subsidiary to repurchase, redeem or otherwise acquire any Shares
or any capital stock of any Subsidiary.  Each outstanding share of capital stock
of each Dialysis Subsidiary is duly authorized, validly issued, fully paid and
nonassessable and each such share owned by the Company or another Dialysis
Subsidiary is free and clear of all security interests, liens, claims, pledges,
options, rights of first refusal, agreements, limitations on the Company's or
such other Dialysis Subsidiary's voting rights, charges and other encumbrances
of any nature whatsoever.  There are no material


                                          10

<PAGE>


outstanding contractual obligations of the Company or any Dialysis Subsidiary to
provide funds to, or make any investment (in the form of a loan, capital
contribution or otherwise) in, Specialty Partners, any other Subsidiary or any
other person.

          SECTION 3.04.  AUTHORITY RELATIVE TO THIS AGREEMENT AND THE SPECIALTY
MERGER AGREEMENT.  The Company has all necessary power and authority to execute
and deliver this Agreement and the Specialty Merger Agreement, to perform its
obligations hereunder and thereunder and to consummate the transactions
contemplated hereby and thereby (the "TRANSACTIONS").  The execution and
delivery of this Agreement and the Specialty Merger Agreement by the Company and
the consummation by the Company of the Transactions have been duly and validly
authorized by all necessary corporate action, and no other corporate proceedings
on the part of the Company are necessary to authorize this Agreement or the
Specialty Merger Agreement or to consummate the Transactions (other than, with
respect to the Specialty Merger Transaction, the reorganization of Specialty
Partners as contemplated in the Specialty Merger Agreement, and other than, with
respect to the Merger, the approval and adoption of this Agreement by the
holders of a majority of the then outstanding Shares if and to the extent
required by applicable law, and the filing and recordation of appropriate merger
documents as required by Delaware Law).  As an amplification and not in
limitation of the immediately preceding sentence, the Board has taken all
actions required to render inapplicable to the Transactions the restrictions on
business combinations contained in Section 203 of the Delaware Law and Article 9
and Article 10 of the Certificate of Incorporation of the Company.  This
Agreement and the Specialty Merger Agreement each have been duly and validly
executed and delivered by the Company and, assuming the due authorization,
execution and delivery by Parent and Purchaser, constitute a legal, valid and
binding obligation of the Company.  

          SECTION 3.05.  NO CONFLICT; REQUIRED FILINGS AND CONSENTS.  (a)  The
execution and delivery of this Agreement and the Specialty Merger Agreement by
the Company do not, and the performance of this Agreement and the Specialty
Merger Agreement by the Company will not, (i) conflict with or violate the
Certificate of Incorporation or By-laws or equivalent organizational documents
of the Company or any Subsidiary, (ii) assuming that all consents, approvals,
authorizations and other actions described in Section 3.05(b) have been made,
conflict with or violate any foreign or domestic law, statute, ordinance, rule,
regulation, order, judgment or decree ("LAW") applicable to the Company or any
Subsidiary or by which any property or asset of the Company or any Subsidiary is
bound, or (iii) result in any breach of or constitute a default (or an event
which with notice or lapse of time or both would become a default) under, or
give to others any right of termination, amendment, acceleration or cancellation
of, or result in the creation of a lien or other encumbrance on any property or
asset of the Company or any Subsidiary pursuant to, any note, bond, mortgage,
indenture, contract, agreement, lease, license, permit, franchise or other
instrument or obligation, except, with respect to clauses (ii) and


                                          11

<PAGE>


(iii), for any such conflicts, violations, breaches, defaults or other
occurrences which would not, individually or in the aggregate, have a Material
Adverse Effect.

          (b)  The execution and delivery of this Agreement and the Specialty
Merger Agreement by the Company do not, and the performance of this Agreement
and the Specialty Merger Agreement by the Company will not, require any consent,
approval, authorization or permit of, or filing with or notification to, any
governmental or regulatory authority, domestic or foreign ("GOVERNMENTAL
AUTHORITY"), except (i) for applicable requirements, if any, of the Exchange
Act, state securities or "blue sky" laws ("BLUE SKY LAWS"), the New York Stock
Exchange (the "NYSE"), state takeover laws, the pre-merger notification
requirements of the HSR Act and filing and recordation of appropriate merger
documents as required by Delaware Law, (ii) except to the extent that the Merger
will require the Company to obtain new Medicare, Medicaid or third party
provider numbers, licenses or similar permits, and (iii) where the failure to
obtain such consents, approvals, authorizations or permits, or to make such
filings or notifications, would not prevent or delay consummation of the Offer,
the Merger or the Specialty Merger Transaction, or otherwise prevent the Company
from performing its obligations under this Agreement or the Specialty Merger
Agreement, and would not, individually or in the aggregate, have a Material
Adverse Effect.

          SECTION 3.06.  PERMITS; COMPLIANCE.  The Company and each of the
Subsidiaries is in possession of all franchises, grants, authorizations,
licenses, permits, easements, variances, exceptions, consents, certificates,
approvals and orders of any Governmental Authority necessary for the Company or
each Dialysis Subsidiary to own, lease and operate its properties or to carry on
the Dialysis Business as it is now being conducted (the "PERMITS"), except where
the failure to have, or the suspension or cancellation of, any of the Permits
would not, individually or in the aggregate, have a Material Adverse Effect,
and, as of the date hereof, no suspension or cancellation of any of the Permits
is pending or, to the knowledge of the Company, threatened, except where the
failure to have, or the suspension or cancellation of, any of the Permits would
not, individually or in the aggregate, have a Material Adverse Effect.  Neither
the Company nor any Dialysis Subsidiary is in conflict with, or in default or
violation of, (i) any Law applicable to the Company or any Dialysis Subsidiary
or by which any property or asset of the Company or any Dialysis Subsidiary is
bound or affected, (ii) any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which the Company or any Dialysis Subsidiary is a party or by which the
Company or any Dialysis Subsidiary or any property or asset of the Company or
any Dialysis Subsidiary is bound or affected or (iii) any Permits, except for
any such conflicts, defaults or violations that would not, individually or in
the aggregate, have a Material Adverse Effect.

          SECTION 3.07.  SEC FILINGS; FINANCIAL STATEMENTS.  (a)  The Company
has filed all forms, reports and documents required to be filed by it with the
SEC since


                                          12

<PAGE>

November 30, 1993 through the date of this Agreement (collectively, the "SEC
REPORTS").  The SEC Reports (i) complied as to form in all material respects
with the requirements of the Securities Act of 1933, as amended (the "SECURITIES
ACT"), or the Exchange Act, as the case may be, and the applicable rules and
regulations thereunder and (ii) did not, at the time they were filed, contain
any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements made
therein, in the light of the circumstances under which they were made, not
misleading.  No Dialysis Subsidiary is required to file any form, report or
other document with the SEC.

          (b)  Each of the consolidated financial statements (including, in each
case, any notes thereto) contained in the SEC Reports was prepared in accordance
with United States generally accepted accounting principles ("GAAP") applied on
a consistent basis throughout the periods indicated (except as may be indicated
in the notes thereto) and each fairly presented the consolidated financial
position, results of operations and cash flows of the Company and the
consolidated Subsidiaries as at the respective dates thereof and for the
respective periods indicated therein except as otherwise noted therein (subject,
in the case of unaudited statements, to normal and recurring year-end
adjustments which did not and are not expected to, individually or in the
aggregate, have a Material Adverse Effect).

          SECTION 3.08.  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since November
30, 1996, except as contemplated by or as disclosed in this Agreement or as
disclosed in any SEC Report filed since November 30, 1996, the Company and the
Dialysis Subsidiaries have conducted the Dialysis Business only in the ordinary
course of the Dialysis Business and, since such date, there has not been (a) any
Material Adverse Effect, (b) any material change by the Company in its
accounting methods, principles or practices, including without limitation, those
used in the calculation of contractual adjustments or bad debts, (c) any
revaluation by the Company of any material assets (including, without
limitation, any writing down of the value of inventory, writing off of notes or
accounts receivable), other than in the ordinary course of the Dialysis
Business, (d) any entry by the Company or any Dialysis Subsidiary into any
commitment or transaction material to the Dialysis Business, (e) except as
specifically contemplated hereby, any declaration, setting aside or payment of
any dividend or distribution in respect of the Shares or any redemption,
purchase or other acquisition of any of its securities or (f) any increase in,
or establishment of, any bonus, insurance, severance, deferred compensation,
pension, retirement, profit sharing, stock option (including, without
limitation, the granting of stock options, stock appreciation rights,
performance awards, or restricted stock awards), stock purchase or other
employee benefit plan, or any other increase in the compensation payable or to
become payable to any officers or key employees of the Company or any
Subsidiary, except increases in the salaries of employees, payment of profit
sharing and bonuses, and granting of stock options in the ordinary course of
business consistent with past practice.

<PAGE>

          SECTION 3.09.  ABSENCE OF LITIGATION.  There is no litigation, suit,
claim, action, proceeding or investigation (an "ACTION") pending or, to the
knowledge of the Company, threatened against the Company or any Subsidiary, or
any property or asset of the Company or any Subsidiary, before any court,
arbitrator or Governmental Authority, which (i) individually or in the
aggregate, reasonably would be expected to have a Material Adverse Effect or
(ii) seeks to delay or prevent the consummation of any Transaction.  Neither the
Company nor any Subsidiary nor any property or asset of the Company or any
Subsidiary is subject to any continuing order of, consent decree, settlement
agreement or other similar written agreement with, or, to the knowledge of the
Company, continuing investigation by, any Governmental Authority, or any order,
writ, judgment, injunction, decree, determination or award of any Governmental
Authority or arbitrator having, individually or in the aggregate, a Material
Adverse Effect.

          SECTION 3.10.  EMPLOYEE BENEFIT PLANS; LABOR MATTERS.  (a) 
Section 3.10 of the Disclosure Schedule contains a true and complete list of all
employee benefit plans (within the meaning of Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA")) and all bonus,
stock option, stock purchase, restricted stock, incentive, deferred
compensation, retiree medical or life insurance, supplemental retirement,
severance or other benefit plans, programs or arrangements, and all employment,
termination, severance or other contracts or agreements to which the Company or
any Subsidiary is a party, with respect to which the Company or any Subsidiary
has any obligation or which are maintained, contributed to or sponsored by the
Company or any Subsidiary for the benefit of any current or former employee,
officer or director of the Company or any Subsidiary (collectively, the
"PLANS").  Each Plan is in writing and the Company has previously furnished or
made available to Parent a true and complete copy of each Plan and a true and
complete copy of each material document prepared in connection with each such
Plan, including, without limitation, (i) a copy of each trust or other funding
arrangement, (ii) each summary plan description and summary of material
modifications, (iii) the most recently filed Internal Revenue Service ("IRS")
Form 5500, (iv) the most recently received IRS determination letter for each
such Plan, and (v) the most recently prepared actuarial report and financial
statement in connection with each such Plan.  Neither the Company nor any
Subsidiary has any express or implied commitment (i) to create, incur liability
with respect to or cause to exist any other employee benefit plan, program or
arrangement, (ii) to enter into any contract or agreement to provide
compensation or benefits to any individual or (iii) to modify, change or
terminate any Plan, other than with respect to a modification, change or
termination required by ERISA or the Internal Revenue Code of 1986, as amended
(the "CODE").

          (b)  None of the Plans is a multiemployer plan, within the meaning of
Section 3(37) or 4001(a)(3) of ERISA (a "MULTIEMPLOYER PLAN"), or a single
employer pension plan, within the meaning of Section 4001(a)(15) of ERISA, for
which the Company or any Subsidiary could incur liability under Section 4063 or
4064 of ERISA (a "MULTIPLE


                                          14

<PAGE>


EMPLOYER PLAN").  None of the Plans is "defined benefit plan" within the meaning
of Section 3(35) of ERISA.  None of the Plans (i) provides for the payment of
separation, severance, termination or similar-type benefits to any person,
(ii) obligates the Company or any Subsidiary to pay separation, severance,
termination or other benefits as a result of any Transaction or (iii) obligates
the Company or any Subsidiary to make any payment or provide any benefit that
could be subject to a tax under Section 4999 of the Code.  None of the Plans
provides for or promises retiree medical, disability or life insurance benefits
to any current or former employee, officer or director of the Company or any
Subsidiary, except for continued healthcare coverage under COBRA.  

          (c)  Each Plan which is intended to be qualified under Section 401(a)
of the Code has received a favorable determination letter from the IRS that such
Plan is so qualified, and each trust established in connection with any Plan
which is intended to be exempt from federal income taxation under Section 501(a)
of the Code has received a determination letter from the IRS that such trust is
so exempt.  No fact or event has occurred since the date of any such
determination letter from the IRS that could adversely affect the qualified
status of any such Plan or the exempt status of any such trust.  Each trust
maintained or contributed to by the Company or any Subsidiary which is intended
to be qualified as a voluntary employees' beneficiary association exempt from
federal income taxation under Sections 501(a) and 501(c)(9) of the Code has
received a favorable determination letter from the IRS that it is so qualified
and so exempt, and no fact or event has occurred since the date of such
determination by the IRS that could adversely affect such qualified or exempt
status.

          (d)  There has been no prohibited transaction (within the meaning of
Section 406 of ERISA or Section 4975 of the Code) with respect to any Plan. 
Neither the Company nor any Subsidiary is currently liable or has previously
incurred any liability for any tax or penalty arising under Section 4971, 4972,
4979, 4980 or 4980B of the Code or Section 502(c) of ERISA, and no fact or event
exists which could give rise to any such liability.  Neither the Company nor any
subsidiary has incurred any liability under, or by operation of, Title IV of
ERISA and no fact or event exists which could give rise to any such liability.  

          (e)  Each Plan is now and has been operated in all respects in
accordance with the requirements of all applicable laws, including, without
limitation, ERISA and the Code, and the Company and each Subsidiary have
performed all obligations required to be performed by them under, are not in any
respect in default under or in violation of any Plan.  The audited consolidated
balance sheet of the Company for the fiscal year ended November 30, 1996
reflects an accrual of all amounts of employer contributions and premiums
accrued but unpaid with respect to the Plans.  


                                          15

          (f)  The Company and the Subsidiaries have not incurred any liability
under, and have complied in all respects with, the Worker Adjustment Retraining
Notification Act and the regulations promulgated thereunder ("WARN") and do not
reasonably expect to incur any such liability as a result of actions taken or
not taken prior to the Effective Time.  

          (g)  Except as set forth in Section 3.10(g) of the Disclosure
Schedule, (i) there are no claims or actions pending or, to the knowledge of the
Company, threatened between the Company or any Subsidiary and any of their
respective employees, which controversies have a Material Adverse Effect;
(ii) neither the Company nor any Subsidiary is a party to any collective
bargaining agreement or other labor union contract applicable to persons
employed by the Company or any Subsidiary, nor, to the knowledge of the Company,
are there any activities or proceedings of any labor union to organize any such
employees; (iii) neither the Company nor any Subsidiary has breached or
otherwise failed to comply with any provision of any such agreement or contract
and there are no grievances outstanding against the Company or any Subsidiary
under any such agreement or contract; (iv) there are no unfair labor practice
complaints pending against the Company or any Subsidiary before the National
Labor Relations Board or any current union representation questions involving
employees of the Company or any Subsidiary; and (v) there is no strike,
slowdown, work stoppage or lockout, or, to the knowledge of the Company, threat
thereof, by or with respect to any employees of the Company or any Subsidiary.

          SECTION 3.11.  OFFER DOCUMENTS; SCHEDULE 14D-9; PROXY STATEMENT. 
Neither the Schedule 14D-9 nor any information supplied by the Company for
inclusion in the Offer Documents shall, at the respective times the
Schedule 14D-9, the Offer Documents or any amendments or supplements thereto are
filed with the SEC or are first published, sent or given to stockholders of the
Company, as the case may be, shall contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements made therein, in the light of the
circumstances under which they are made, not misleading.  Neither the proxy
statement to be sent to the stockholders of the Company in connection with the
Stockholders' Meeting (as hereinafter defined) nor the information statement to
be sent to such stockholders, as appropriate (such proxy statement or
information statement, as amended or supplemented, being referred to herein as
the "PROXY STATEMENT"), shall, at the date the Proxy Statement (or any amendment
or supplement thereto) is first mailed to stockholders of the Company, at the
time of the Stockholders' Meeting and at the Effective Time, contain any untrue
statement of a material fact, or omit to state any material fact required to be
stated therein or necessary in order to make the statements made therein, in the
light of the circumstances under which they are made, not misleading or
necessary to correct any statement in any earlier communication with respect to
the solicitation of proxies for the Stockholders' Meeting which shall have
become false or misleading.  Notwithstanding the foregoing, no representation or
warranty is made by the Company with respect to statements therein based on
information supplied by


                                          16

<PAGE>

Parent or Purchaser or any of their representatives which is contained in the
Schedule 14D-9, the Offer Documents, the Proxy Statement or any amendment or
supplement thereto.  The Schedule 14D-9 and the Proxy Statement shall comply in
all material respects as to form with the requirements of the Exchange Act and
the applicable rules and regulations thereunder.

          SECTION 3.12.  PROPERTY.  The Company and the Dialysis Subsidiaries
have sufficient title to, or right to use, all their properties and assets
necessary to conduct their respective businesses as currently conducted or as
contemplated to be conducted, with only such exceptions as, individually or in
the aggregate, would not have a Material Adverse Effect.

          SECTION 3.13.  TRADEMARKS, PATENTS AND COPYRIGHTS.  To the knowledge
of the Company, the Company and the Dialysis Subsidiaries own or possess
adequate licenses or other valid rights to use all patents, patent rights,
trademarks, trademark rights, trade names, trade name rights, copyrights,
servicemarks, trade secrets, applications for trademarks and for servicemarks,
know-how and other proprietary rights and information used or held for use in
connection with the Dialysis Business as currently conducted or as contemplated
to be conducted, and the Company is unaware of any assertion or claim
challenging the validity of any of the foregoing which, individually or in the
aggregate, would have a Material Adverse Effect.  To the knowledge of the
Company, the conduct of the Dialysis Business as currently conducted does not
and will not infringe upon any patent, patent right, license, trademark,
trademark right, trade name, trade name right, servicemark or copyright of any
third party that, individually or in the aggregate, would have a Material
Adverse Effect.  To the knowledge of the Company, there are no infringements of
any propriety rights owned by or licensed by or to the Company or any Dialysis
Subsidiary which, individually or in the aggregate, would have a Material
Adverse Effect.

          SECTION 3.14.  TAXES. (a)  The Company and the Subsidiaries have
timely filed all Tax Returns and reports required to be filed by them, or
extensions of time for such filings have been filed, and such returns and
reports are in all material respects true, complete and correct.  The Company
and the Subsidiaries have paid and discharged within the time and in the manner
prescribed by the law all Taxes that are due and payable, other than such
payments as are being contested in good faith by appropriate proceedings.  The
accruals and reserves for Taxes reflected in the Company's audited consolidated
balance sheet for the fiscal year ended November 30, 1996 are adequate to cover
all Taxes accruable through such date (including interest and penalties, if any,
thereon) in accordance with GAAP.  Neither the IRS nor any other taxing
authority or agency, domestic or foreign, is now asserting or, to the knowledge
of the Company, threatening to assert against the Company or any Subsidiary any
deficiency or claim for additional Taxes or interest thereon or penalties in
connection therewith.  Neither the Company nor any Subsidiary has granted any
waiver of any statute of limitations with respect to, or any extension of a
period for the



                                          17

assessment of, any income Tax.  The statute of limitations for the assessment of
any federal income Taxes has expired for all income Tax Returns of the Company
and each of the Subsidiaries or such income Tax Returns of the Company and each
of the Subsidiaries have been examined by the IRS for all periods.  There are no
Tax liens upon the assets of the Company or any Subsidiaries except for
statutory liens for current Taxes not yet due.  No audits or other
administrative proceeding or court proceedings are presently pending with regard
to any Taxes or Tax Returns of the Company or any of the Subsidiaries.  Neither
the Company nor any Subsidiary is a party to any agreement relating to
allocating or sharing of Taxes which has not been disclosed on its Tax Returns. 
No consent under Section 341(f) of the Code has been filed with respect to the
Company or any Subsidiary.  Neither the Company nor any of the Subsidiaries has
received a written ruling relating from, or entered into a written and legally
binding agreement with, a taxing authority relating to Taxes.

          (b)  "TAX" or "TAXES" means any and all taxes, fees, levies, duties,
tariffs, imposts, and other charges of any kind (together with any and all
interest, penalties, additions to tax and additional amounts imposed with
respect thereto) imposed by any government or taxing authority, including,
without limitation: taxes or other charges on or with respect to income,
franchises, windfall or other profits, gross receipts, property, sales, use,

similar charges.

          (c)  "TAX RETURN" means any report, return, information statement,
payee statement or other information required to be provided to any federal,
state, local or foreign government or taxing authority, or otherwise retained,
with respect to Taxes.

                                ADDITIONAL AGREEMENTS

          SECTION 6.01.  STOCKHOLDERS' MEETING.  (a)  If required by applicable
law in order to consummate the Merger, the Company, acting through the Board,
shall, in accordance with applicable law and the Company's Certificate of
Incorporation and By-laws, (i) duly call, give notice of, convene and hold an
annual or special meeting of its stockholders as soon as practicable following
consummation of the Offer for the purpose of considering and taking action on
this Agreement and the transactions contemplated hereby (the "STOCKHOLDERS'
MEETING") and (ii) except if the Board determines in good faith an alternative
action to be necessary in accordance with its fiduciary duties to the Company's
stockholders under applicable law as advised by outside legal counsel,
(A) include in the Proxy Statement the unanimous recommendation of the Board
that the holders of the Shares approve and adopt this Agreement and the
Transactions and (B) use its reasonable efforts to obtain such approval and
adoption of the holders of Shares.  At the Stockholders' Meeting, Parent and
Purchaser shall cause all Shares then owned by them and their subsidiaries to be
voted in favor of the approval and adoption of this Agreement and the
transactions contemplated hereby.

          (b)  Notwithstanding the foregoing, in the event that Purchaser shall
acquire at least 90 percent of the then outstanding Shares, the parties hereto
agree, at the request of Purchaser, subject to Article VII, to take all
necessary and appropriate action to cause the Merger to become effective, in
accordance with Section 253 of Delaware Law, as soon as reasonably practicable
after such acquisition, without a meeting of the stockholders of the Company.

          SECTION 6.02.  PROXY STATEMENT.  If required by applicable law, as
soon as reasonably practicable following consummation of the Offer, the Company
shall file the Proxy Statement with the SEC under the Exchange Act, and shall
use its reasonable efforts to have the Proxy Statement cleared by the SEC. 
Parent, Purchaser and the Company shall cooperate with each other in the
preparation of the Proxy Statement, and the Company shall notify Parent of the
receipt of any comments of the SEC with respect to the Proxy Statement and of
any requests by the SEC for any amendment or supplement thereto or for
additional information and shall provide to Parent promptly copies of all
correspondence between the Company or any representative of the Company and the
SEC.  The Company shall give Parent and its counsel the reasonable opportunity
to review the Proxy Statement prior to its being filed with the SEC and shall
give Parent and its counsel the opportunity to review all amendments and
supplements to the Proxy Statement and all responses to requests for additional
information and replies to comments prior to their being filed with, or sent to,
the SEC.  Each of the Company, Parent and Purchaser agrees to use its reasonable
efforts, after consultation with the other parties hereto, to respond promptly
to all such comments of and


                                          26

<PAGE>


requests by the SEC and to cause the Proxy Statement and all required amendments
and supplements thereto to be mailed to the holders of Shares entitled to vote
at the Stockholders' Meeting at the earliest practicable time.

          SECTION 6.03.  COMPANY BOARD REPRESENTATION; SECTION 14(F).  (a) 
Promptly upon the purchase by Purchaser of Shares pursuant to the Offer, and
from time to time thereafter, Purchaser shall be entitled to designate up to
such number of directors, rounded up to the next whole number, on the Board as
shall give Purchaser representation on the Board equal to the product of the
total number of directors on the Board (giving effect to the directors elected
pursuant to this sentence) multiplied by the percentage that the aggregate
number of Shares beneficially owned by Purchaser or any affiliate of Purchaser
following such purchase bears to the total number of Shares then outstanding,
and the Company shall, at such time, promptly take all actions necessary to
cause Purchaser's designees to be elected as directors of the Company, including
increasing the size of the Board or securing the resignations of incumbent
directors or both.  At such times, the Company shall, upon the written request
of Purchaser, use its reasonable efforts to cause persons designated by
Purchaser to constitute the same percentage as persons designated by Purchaser
shall constitute of the Board of (i) each committee of the Board, (ii) each
board of directors of each domestic Dialysis Subsidiary and (iii) each committee
of each such board, in each case only to the extent permitted by applicable law.
Notwithstanding the foregoing, until the earlier of (i) the time Purchaser
acquires a majority of the then outstanding Shares on a fully diluted basis and
(ii) the Effective Time, the Company shall use its reasonable efforts to ensure
that all the members of the Board and each committee of the Board and such
boards and committees of the domestic Dialysis Subsidiaries as of the date
hereof who are not employees of the Company shall remain members of the Board
and of such boards and committees, except for the members not standing for
re-election at the Company's 1997 annual meeting of stockholders.

          (b)  The Company shall promptly take all actions required pursuant to
Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder in order
to fulfill its obligations under this Section 6.03 and shall include in the
Schedule 14D-9 such information with respect to the Company and its officers and
directors as is required under Section 14(f) and Rule 14f-1 to fulfill such
obligations.  Parent or Purchaser shall supply to the Company and be solely
responsible for any information with respect to either of them and their
nominees, officers, directors and affiliates required by such Section 14(f) and
Rule 14f-1.

          (c)  Following the election of designees of Purchaser pursuant to this
Section 6.03, prior to the Effective Time, any amendment of this Agreement or
the Certificate of Incorporation or By-laws of the Company, any termination of
this Agreement by the Company, any extension by the Company of the time for the
performance of any of the obligations or other acts of Parent or Purchaser or
waiver of any of the Company's rights


                                          27

<PAGE>

hereunder shall require the concurrence of a majority of the directors of the
Company then in office who neither were designated by Purchaser nor are
employees of the Company.

          SECTION 6.04.  ACCESS TO INFORMATION; CONFIDENTIALITY.  (a)  From the
date hereof to the Effective Time, upon reasonable notice, the Company shall,
and shall cause the Dialysis Subsidiaries and the officers, directors,
employees, auditors and agents of the Company and the Dialysis Subsidiaries to,
afford the officers, employees and agents of Parent and Purchaser complete
access during normal business hours to the officers, employees, agents,
properties, offices, plants and other facilities, books and records of the
Company and each Dialysis Subsidiary, and shall furnish Parent and Purchaser
with all financial, operating and other data and information as Parent or
Purchaser, through its officers, employees or agents, may reasonably request. 
Parent and Purchaser shall make all reasonable efforts to minimize any
disruption to the Dialysis Business which may result from the requests for data
and information hereunder.

          (b)  All information obtained by Parent or Purchaser pursuant to this
Section 6.04 shall be kept confidential in accordance with the confidentiality
agreement, dated October 7, 1996 (the "CONFIDENTIALITY AGREEMENT"), between
Parent and the Company.
 
          (c)  No investigation pursuant to this Section 6.04 shall affect any
representation or warranty in this Agreement of any party hereto or any
condition to the obligations of the parties hereto.

          SECTION 6.05.  NO SOLICITATION.  (a)  The Company shall, and shall
direct and use all reasonable efforts to cause its officers, directors,
employees, representatives and agents to immediately cease any discussions or
negotiations with any parties that may be ongoing with respect to any
"acquisition proposal" (as defined below in this Section 6.05(a)).  Except with
respect to the Specialty Merger Transaction, the Company shall not, nor shall it
permit any of its subsidiaries to, nor shall it authorize or permit any officer,
director or employee of, or any investment banker, accountant, attorney or other
advisor or representative of, the Company or any of its subsidiaries to,
directly or indirectly, (i) solicit or initiate, or knowingly encourage the
submission of, any acquisition proposal or (ii) participate in any discussions
or negotiations regarding, or furnish to any person any information with respect
to, or take any other action to facilitate the making of any proposal that
constitutes, or may reasonably be expected to lead to, an acquisition proposal;
PROVIDED, HOWEVER, that if and to the extent, prior to the acceptance for
payment of Shares pursuant to the Offer, the Board determines in good faith that
it is necessary to do so in accordance with its fiduciary duties to the
Company's stockholders under applicable law as advised by outside legal counsel,
the Company may, in response to an unsolicited acquisition proposal, and subject
to compliance with Section 6.05(c), (x) furnish information with respect to the
Company to any persons pursuant to a customary confidentiality agreement on
terms no less favorable to the Company than those contained in the
Confidentiality Agreement and (y)


                                          28

<PAGE>

participate in negotiations regarding such acquisition proposal.  For purposes
of this Agreement, "ACQUISITION PROPOSAL" means any bona fide proposal or offer
from any person relating to any direct or indirect acquisition or purchase of
all or a substantial part of the assets of the Company or any of the Dialysis
Subsidiaries or of over 20% of any class of equity securities of the Company or
any of the Dialysis Subsidiaries, any tender offer or exchange offer that if
consummated would result in any person beneficially owning 20% or more of any
class of equity securities of the Company or any of the Dialysis Subsidiaries,
any merger, consolidation, business combination, sale of all or substantially
all of the assets, recapitalization, liquidation, dissolution or similar
transaction involving the Company or any of the Dialysis Subsidiaries, other
than the Transactions, or any other transaction the consummation of which would
reasonably be expected to impede, interfere with, prevent or materially delay
the Offer or the Merger or which would reasonably be expected to dilute
materially the benefits to Parent of the Offer or Merger.

          (b)  Except as set forth in this Section 6.05, neither the Board nor
any committee thereof shall (i) withdraw or modify, or propose to withdraw or
modify, in a manner adverse to Parent, the approval or recommendation by the
Board or any such committee of the Offer, this Agreement or the Merger, (ii)
approve or recommend, or propose to approve or recommend, any acquisition
proposal or (iii) enter into any agreement with respect to any acquisition
proposal.  Notwithstanding the foregoing, in the event prior to the time of
acceptance for payment of Shares pursuant to the Offer the Board determines in
good faith that it is necessary to do so in accordance with its fiduciary duties
to the Company's stockholders under applicable law as advised by outside legal
counsel, the Board may withdraw or modify its approval or recommendation of the
Offer, the Merger or this Agreement in order to enter into a definitive
agreement with respect to a Superior Proposal (as defined below) and may
terminate this Agreement pursuant to Section 8.01(d)(ii) (and concurrently with
or after such termination may cause the Company to enter into any agreement with
respect to any Superior Proposal).  For purposes of this Agreement, a "SUPERIOR
PROPOSAL" means any bona fide proposal made by a third party to acquire,
directly or indirectly, for consideration consisting of cash and/or securities,
more than 50% of the combined voting power of the Shares then outstanding or all
or substantially all the assets of the Company and otherwise on terms which the
Board determines in its good faith judgment (based on the advice of a financial
advisor of nationally recognized reputation) to be more favorable to the
Company's stockholders than the Offer and the Merger and for which financing, to
the extent required, is then committed.  

          (c)  In addition to the obligations of the Company set forth in
paragraphs (a) and (b) of this Section 6.05, the Company shall promptly advise
Parent orally and in writing of any request for information or of any
acquisition proposal, the material terms and conditions of such request or
acquisition proposal and the identity of the person making such request or
acquisition proposal.


                                          29

<PAGE>

          (d)  Nothing contained in this Section 6.05 shall prohibit the Company
from taking and disclosing to its stockholders a position contemplated by
Rule 14e-2(a) promulgated under the Exchange Act or from making any disclosure
to the Company's stockholders if the Board determines in good faith that it is
necessary to do so in accordance with its fiduciary duties to the Company's
stockholders under applicable law as advised by outside legal counsel, PROVIDED,
HOWEVER, neither the Company nor the Board nor any committee thereof shall,
except as permitted by Section 6.05(b), withdraw or modify, or propose publicly
to withdraw or modify, its position with respect to the Offer, this Agreement or
the Merger or to approve or recommend, or propose publicly to approve or
recommend, an acquisition proposal.  

          (e)  The Company agrees not to release any third party from, or waive
any provision of, any confidentiality or standstill agreement to which the
Company is a party.

          SECTION 6.06.  EMPLOYEE STOCK OPTIONS AND OTHER EMPLOYEE BENEFITS. 
(a)  Immediately prior to the Effective Time, the Company shall take all such
actions as shall be necessary to cause all stock options (and any related
alternative rights) to purchase shares of Company Common Stock (the "EMPLOYEE
STOCK OPTIONS") granted under the Company Stock Option Plans (including those
granted to current or former employees, consultants and directors of the Company
or any of its Subsidiaries), which Employee Stock Options are outstanding
immediately prior to the Effective Time (whether or not then presently
exercisable or vested), to be cancelled.  In exchange for the cancellation of
such Employee Stock Option, the holder thereof shall be entitled to receive from
the Surviving Corporation an amount in cash equal to the product of the
difference between the Per Share Amount and the per share exercise price of such
Employee Stock Option, and the number of shares of Company Common Stock covered
by such Employee Stock Option.  All payments in respect of Employee Stock
Options shall be made after the Effective Time and not later than thirty days
following the Effective Time, subject to the Company's collection of all
applicable withholding taxes.  The Company Stock Option Plans shall terminate as
of the Effective Time and thereafter the only rights of participants therein
shall be the right to receive the consideration set forth in the previous
sentence.  Prior to the Effective Time, the Company shall cause each holder of
an outstanding Employee Stock Option to consent to the cancellation of the
Employee Stock Options held by such holder in consideration for the payment
provided herein, and shall take such other action as may be necessary to carry
out the terms of this Section 6.06(a).  

          (b)  Section 6.06(b) of the Disclosure Schedule contains a list of
each employee of the Company or any Dialysis Subsidiary who has a written
employment agreement that provides for the payment of severance or similar-type
payments or benefits to such employee following such employee's termination of
employment with the Company and its Dialysis Subsidiaries (the "EMPLOYMENT
CONTRACTS").  


                                          30

<PAGE>

          (c)  Following the Effective Time the Company will maintain for
eligible participants other than employees who will be employed by Specialty
Partners after the date of the Specialty Merger Transaction a retention bonus
and deferred compensation arrangement substantially in the form of Annex B to
this Agreement.

          SECTION 6.07.  SPECIALTY MERGER AGREEMENT.  The Company shall use
reasonable commercial efforts to perform its obligations under the Specialty
Merger Agreement and to consummate the Specialty Merger Transaction on the terms
and conditions set forth in the Specialty Merger Agreement.  The Company will
not amend or modify any material provision of, or waive any of its rights under
the Specialty Merger Agreement.

          SECTION 6.08.  DIRECTORS' AND OFFICERS' INDEMNIFICATION AND INSURANCE.
(a)  The Certificate of Incorporation of the Surviving Corporation shall contain
provisions no less favorable with respect to indemnification than are set forth
in Article Eight of the Certificate of Incorporation of the Company, which
provisions shall not be amended, repealed or otherwise modified for a period of
six years from the Effective Time in any manner that would affect adversely the
rights thereunder of individuals who at the Effective Time were directors,
officers, employees, fiduciaries or agents of the Company, unless such
modification shall be required by law.  To the extent that the obligations under
such provisions are not fully performed by the Surviving Corporation, Parent
agrees to perform fully the obligations thereunder for the remaining period.

          (b)  Parent or the Surviving Corporation shall use its best efforts to
maintain in effect for a period of not less than six years from the Effective
Time the current directors' and officers' liability insurance policies
maintained by the Company (provided that Parent or the Surviving Corporation may
substitute therefor policies of at least the same coverage containing terms and
conditions which are not materially less favorable to such directors and
officers) with respect to matters occurring prior to the Effective Time;
PROVIDED, HOWEVER, that if the existing policies expire, are terminated or
cancelled during such period, Parent or Surviving Corporation will use its best
efforts to obtain substantially similar policies.  Notwithstanding the
foregoing, in no event shall Parent or the Surviving Corporation be required to
expend pursuant to this Section 6.08(b) more than an amount per year equal to
150% of current annual premiums (the "CURRENT PREMIUMS") paid by the Company for
such insurance (which premiums the Company represents and warrants to be
$180,000 in the aggregate); and, PROVIDED, FURTHER, that if the Parent or the
Surviving Corporation is not able to obtain the amount of insurance required by
this Section 6.08(b) for such aggregate premium, Parent or the Surviving
Corporation shall obtain as much insurance as can be obtained for an annual
premium of 150% of the Current Premiums.

          (c)  In the event the Company, the Surviving Corporation or the Parent
or any of their respective successors or assigns (i) consolidates with or merges
into any other person and shall not be the continuing or surviving corporation
or entity of such


                                          31

<PAGE>

consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any person, then, and in each such case, proper
provision shall be made so that the successors and assigns of the Company, the
Surviving Corporation or the Parent, as the case may be, shall assume the
obligations set forth in this Section 6.08.

          SECTION 6.09.  RIGHTS PLAN.  The Company shall not redeem the Company
Rights prior to the Effective Time unless required to do so by order of a court
of competent jurisdiction.  The Board shall take, or cause to be taken, such
action as is necessary to effect the amendments to the Rights Plan as approved
by the Board and described in Section 3.18.

          SECTION 6.10.  CONDUCT OF SPECIALTY BUSINESS.  From the date hereof
until the earlier of the consummation of the Specialty Merger Transaction and
the termination of this Agreement pursuant to Section 8.01, the Company shall
operate Specialty Partners, the Specialty Subsidiaries, and the Specialty
Business consistent with Section 2 of the Services Agreement dated as of the
date hereof between the Company and Specialty Partners and the Company and the
Dialysis Subsidiaries shall not make any contribution, payment or other transfer
to Specialty Partners or any Specialty Subsidiary of cash, cash equivalents,
marketable securities or any other asset, and Specialty Partners and the
Specialty Subsidiaries shall not make any contribution, payment or other
transfer to the Company or any Dialysis Subsidiary of cash, cash equivalents,
marketable securities or any other asset.

          SECTION 6.11.  NOTIFICATION OF CERTAIN MATTERS.  The Company shall
give prompt notice to Parent, and Parent shall give prompt notice to the
Company, of (i) the occurrence, or non-occurrence, of any event the occurrence,
or non-occurrence, of which would cause any representation or warranty contained
in this Agreement to be untrue or inaccurate in any material respect when made
and (ii) any material failure of the Company, Parent or Purchaser, as the case
may be, to comply with or satisfy any covenant, condition or agreement to be
complied with or satisfied by it hereunder; PROVIDED, HOWEVER, that the delivery
of any notice pursuant to this Section 6.11 shall not limit or otherwise affect
the remedies available hereunder to the party receiving such notice.

          SECTION 6.12.  FURTHER ACTION; REASONABLE EFFORTS.  (a) Upon the terms
and subject to the conditions hereof, each of the parties hereto shall (i) make
promptly its respective filings, and thereafter make any other required
submissions, under the HSR Act with respect to the Transactions and (ii) use its
reasonable efforts to take, or cause to be taken, all appropriate action, and to
do, or cause to be done, all things necessary, proper or advisable under
applicable laws and regulations to consummate and make effective the
Transactions, including, without limitation, using its reasonable efforts to
obtain all licenses, permits (including, without limitation, Environmental
Permits), consents, approvals, authorizations, qualifications and orders of
governmental authorities and parties to contracts with the Company and the
Subsidiaries as are necessary for the consummation of the Transactions and to
fulfill the conditions to the Offer and the Merger.  In case at any time


                                          32

<PAGE>

after the Effective Time any further action is necessary or desirable to carry
out the purposes of this Agreement, the proper officers and directors of each
party to this Agreement shall use their reasonable efforts to take all such
action.

          (b)  Each of the parties hereto agree to cooperate and use their
reasonable efforts vigorously to contest and resist any action, including
administrative or judicial action, and to have vacated, lifted, reversed or
overturned any decree, judgment, injunction or other order (whether temporary,
preliminary or permanent) (an "ORDER") that is in effect and that restricts,
prevents or prohibits the consummation of the Offer, the Merger or any other
Transactions, including, without limitation, by vigorously pursuing all
available avenues of administrative and judicial appeal.

          SECTION 6.13.  PUBLIC ANNOUNCEMENTS.  Unless otherwise required by
applicable law or stock exchange requirements applicable to any party hereto,
Parent and the Company shall consult with each other before issuing any press
release or otherwise making any public statements with respect to this Agreement
or any Transaction and shall not issue any such press release or make any such
public statement prior to such consultation.

          SECTION 6.14.  CONFIDENTIALITY AGREEMENT.  The Company hereby waives
the provisions of the Confidentiality Agreement as and to the extent necessary
to permit the consummation of each Transaction.  Upon the acceptance for payment
of Shares pursuant to the Offer, the Confidentiality Agreement shall be deemed
to have terminated without further action by the parties thereto.

     injunction or other order (whether temporary, preliminary or permanent)
     which is then in effect and has the effect of making the acquisition of
     Shares by Parent or Purchaser or any affiliate of either of them illegal or
     otherwise restricting, preventing or prohibiting consummation of the Offer
     or Merger; and

     Company duly authorized by the Boards of Directors of Parent, Purchaser and

     temporary restraining order or preliminary injunction, as the case may be,
     such date shall be extended to the earlier of the date of expiration or
     termination of such waiting period or the lifting of such injunction or
     order or October 31, 1997; PROVIDED, FURTHER, HOWEVER, that the right to
     terminate this Agreement under this Section 8.01(b) shall not be available

               (c)  By Parent if due to an occurrence or circumstance, other
     than a breach by Parent or Purchaser of their obligations hereunder, that

     hereto (which failure cannot be cured or, if capable of being cured, has
     not been cured in all material respects within 30 days after notice to the

     Parent, in good faith that it is necessary to do so in accordance with its
     fiduciary duties to the Company's stockholders under applicable law as
     advised by outside legal counsel; PROVIDED, HOWEVER, that any termination
     of this Agreement pursuant to this Section 8.01(d)(ii) shall not be
     effective until the Company has made full payment of all amounts provided
     under Section 8.03, or (iii) if Parent or Purchaser shall have failed to

     shall have breached any of their respective representations, warranties,
     covenants or other agreements contained herein in a manner that materially

<PAGE>

Sections 8.03 and 9.01 and (ii) nothing herein shall relieve any party from
liability for any breach hereof.

          SECTION 8.03.  FEES AND EXPENSES.  (a)  In the event that

               (i)  this Agreement is terminated pursuant to

               (ii) (x)  an acquisition proposal is commenced, publicly
     proposed, publicly disclosed or communicated to the Company or any
     representative or agent thereof after the date of this Agreement and prior

later than one business day after the first of such events shall have occurred)
a fee of $50,000,000 (the "FEE"), which amount shall be payable in immediately
available funds, plus all Expenses (as hereinafter defined); PROVIDED, HOWEVER,
that no Fee shall be payable under Section 8.03(ii) if, at the time of
termination under Section 8.01, Parent or Purchaser is in material breach of
their respective material covenants and agreements contained in this Agreement
or their respective representations and warranties contained herein.

          (b)  If this Agreement is terminated for any reason whatsoever and

covenants and agreements contained in this Agreement or their respective
representations and warranties contained in this Agreement, the Company shall,
whether or not any payment is made pursuant to Section 8.03(a), reimburse each
of Parent, Purchaser and their respective stockholders and affiliates (not later

and documented out-of-pocket expenses and fees up to $4,000,000 in the aggregate
(including, without limitation, fees and expenses payable to all banks,

<PAGE>


financing commitments or agreements relating thereto (all of the foregoing being
referred to herein collectively as the "EXPENSES").

          (c)  Except as set forth in this Section 8.03, all costs and expenses
incurred in connection with this Agreement and the Transactions shall be paid by
the party incurring such expenses, whether or not any Transaction is
consummated.

          (d)  In the event that the Company shall fail to pay the Fee or any
Expenses when due, the term "Expenses" shall be deemed to include the costs and
expenses actually incurred or accrued by Parent, Purchaser and their respective
stockholders and affiliates (including, without limitation, fees and expenses of

this Agreement may be amended by the parties hereto by action taken by or on
behalf of their respective Boards of Directors at any time prior to the

  Bonus:            The Maximum Target Bonus for each Tier 1 Participant and
                    Tier 2 Participant will be an amount previously disclosed in
                    writing to Parent and agreed to by Parent.  In addition, any
                    amount payable under the Plan which is not allocated as of
                    the closing date of the Merger may thereafter be allocated
                    as agreed by David Barry and a designated officer of Parent.
                    Such amount shall not exceed $300,000. 

Deferred
  Compensation
  for Tier 1
  Participants:     The Company shall establish on its books and records a
                    deferred compensation account for each Tier 1 Participant.
                    Each Tier 1 Participant shall have a one-time election to 
                    defer some or all of the stay bonus payable to such 
                    participant. Amounts deferred will be credited to the Tier I
                    Participant's deferred compensation account.  Amounts
                    credited to the account will be credited with notional
                    interest at a to-be-determined rate from the date of
                    crediting to the time of payment.

                    Subject to the forfeiture provisions set forth below,
                    amounts held in a Tier 1 Participant's deferred compensation
                    account will be paid to the participant in three equal
                    annual installments beginning on the LATER to occur of (i)
                    the first day of the month following the participant's
                    termination of employment with the Company and (ii) the
                    first day of the month following the month the participant
                    attains age 60.

Effect of 
  Termination
  of Employment:    CAUSE.  If a Tier 1 Participant or a Tier 2 Participant (a
                    "Participant") is terminated for cause (to be defined), the
                    Participant will not be eligible for any future cash
                    payments of

                                         B-2

<PAGE>


                    stay bonus and all amounts in the deferred compensation
                    account, if any, will be immediately forfeited.

                    VOLUNTARY RESIGNATION.  If a Participant voluntarily
                    resigns, the Participant will not be eligible for any future
                    cash payments of stay bonus and will not be eligible for any
                    future credits to the deferred compensation account.  The
                    balance of the deferred compensation account will be paid in
                    the manner set forth above.

                    TERMINATION WITHOUT CAUSE.  If a Participant's employment is
                    terminated by the Company without Cause, the balance of
                    payments of the stay bonus and the balance of credits to the
                    deferred compensation account will be made in the manner
                    contemplated above.  The balance of the deferred
                    compensation account will be paid in the manner set forth
                    above.

                    DEATH OR DISABILITY.  If a Participant's employment is
                    terminated due to death or disability, all payments of the
                    stay bonus and credits to the deferred compensation account
                    will be accelerated and the balance of the deferred
                    compensation account will be paid to the Participant or the
                    Participant's estate, as applicable, within 90 days.

Protective
   Covenants:       As a condition to the payments above, Participants will
                    agree as follows:

                    Each Participant whose Maximum Target Bonus equals or
                    exceeds $200,000 will agree not to compete with the Company
                    while employed and for the one-year period following
                    termination of employment, but in no event longer than
                    three years from the Effective Time.

                    All Participants will agree not to solicit the customers or
                    employees of the Company while employed and for the one-year
                    period following termination of employment.

                    All Participants will agree not to disclose any confidential
                    or proprietary information at any time.

                    Breach by a Participant of any of these protective covenants
                    will result in immediate forfeiture of any right to future
                    payment of stay bonus and immediate forfeiture of amounts
                    credited to the

                    deferred compensation account.  The Company shall also be
                    entitled to appropriate equitable relief to enjoin any such
                    breach.

Excluded
  Employees:        No individual who is or becomes an employee of Specialty
                    Partners shall be eligible to participate in the
                    arrangement.

                    terms above.

                         AGREEMENT AND PLAN OF REORGANIZATION

    THIS AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is entered 
into as of this 5th day of May, 1997, by and among VSP Holdings, Inc., a 
Delaware corporation (the "Acquiror"), VSP Acquisition, Inc., a Delaware 
corporation and a wholly owned subsidiary of Acquiror (the "Merger Sub"), VSP 
Holdings II, Inc., a Delaware corporation ("Acquiror II"), Vivra Specialty 
Partners, Inc., a Nevada corporation (the "Company"), and Vivra Incorporated, 
a Delaware corporation (the "Parent").

                                       RECITALS

    A. Acquiror, Merger Sub, the Company and the Parent have each determined 
to engage in the transactions contemplated hereby, pursuant to which (i) 
Merger Sub will merge with and into the Company (the "Merger") and (ii) 
except in certain specified circumstances, (a) each share of the Company's 
Class A common stock, $0.01 par value per share (the "Class A Common Stock"), 
and each share of the Company's Class B common stock, $0.01 par value per 
share (the "Class B Common Stock," and, together with the Class A Common 
Stock, the "Common Stock") shall be converted into rights to receive cash 
consideration in the manner herein described, and (b) each outstanding option 
granted by the Company to purchase shares of Common Stock shall be converted 
into the right to receive options to purchase shares of Acquiror's Class B 
common stock, $0.01 par value per share (the "Acquiror Class B Common Stock").

    B. The respective Boards of Directors of the Company and Parent have each 
approved the Merger and this Agreement.  The holders of a majority of the 
issued and outstanding shares of Common Stock have approved the Merger and 
this Agreement.

    C. The respective Boards of Directors of Acquiror and Merger Sub have 
each approved the Merger and this Agreement.  Acquiror, as the sole 
stockholder of Merger Sub, has approved the Merger and this Agreement.

    D. The parties may make an election under Section 338(h)(10) of the 
Internal Revenue Code of 1986, as amended (the "Code") with respect to such 
transactions.

    E. Reference is made to that certain Agreement and Plan of Merger (the 
"Vivra Agreement"), dated as of May 5, 1997, among Incentive AB, a 
corporation organized under the laws of Sweden ("Incentive"), HH Acquisition

which Purchaser shall make a cash tender offer (the "Offer") to acquire all 
of the issued and outstanding shares of common stock of Parent (the "Parent

and conditions.

    NOW, THEREFORE, in consideration of the foregoing and the mutual 
representations, warranties, covenants and agreements set forth herein, the 
parties agree as follows:


<PAGE>

                                      ARTICLE I.
                                      THE MERGER

    Section 1.01  The Merger.  Subject to the terms and conditions of this
Agreement, Merger Sub shall be merged with and into the Company in accordance
with the General Corporation Law of the State of Nevada ("Nevada Law") and the
General Corporation Law of the State of Delaware ("Delaware Law"), whereupon the
separate existence of Merger Sub shall cease, and the Company shall be the
surviving corporation (the "Surviving Corporation").

    Section 1.02  VHI Acquisition.  Subject to any adjustment to such terms
pursuant to Section 1.12, simultaneously with the consummation of the Merger,
Parent will sell and transfer to Acquiror II all of the outstanding capital
stock of Vivra Heart Imaging, Inc., a Nevada corporation ("VHI"), owned by
Parent in exchange for a payment in cash by Acquiror II to Parent of the VHI
Consideration (as defined in Section 1.13) (such transaction being hereinafter
referred to as the "VHI Acquisition" and, together with the Merger, the
"Transactions").

    Section 1.03  Closing.  The closing of the Transactions or the Alternative
Transaction (as hereinafter defined in Section 1.12), as the case may be (the
"Closing"), shall take place as soon as practicable on the first business day
after satisfaction or waiver of the conditions set forth herein, at the offices
of Brobeck, Phleger & Harrison LLP, Spear Street Tower, One Market, San
Francisco, California  94105, or at such other time and place as the parties
shall designate in writing (the "Closing Date").

    Section 1.04  Effective Time.  Concurrent with the Closing, the Company
and Merger Sub shall file this Agreement or a certificate of merger or a
certificate of ownership and merger (the "Certificate of Merger") with the
Offices of the Secretary of State of the states of Nevada and Delaware in
accordance with Nevada Law and Delaware Law, respectively.  The Merger shall
become effective at such time as the Certificate of Merger is duly filed (the
date of such filing being hereinafter referred to as the "Effective Date" and
the time of such filing being hereinafter referred to as the "Effective Time"). 
It is the intention of the parties that this Agreement shall constitute an
agreement of merger under Section 92A.120 of Nevada Law and under Section 252 of
Delaware Law.

    Section 1.05  Effect of the Merger.  At the Effective Time, the effect of
the Merger shall be as provided in the applicable provisions of Nevada Law and
Delaware Law.  Without limiting the generality of the foregoing, and subject
thereto, at the Effective Time all the property, rights, privileges, powers and
franchises of the Company and Merger Sub shall vest in the Surviving
Corporation, and all debts, liabilities, obligations, restrictions, disabilities
and duties of the Company and Merger Sub shall become the debts, liabilities,
obligations, restrictions, disabilities and duties of the Surviving Corporation.

    Section 1.06  Certificate of Incorporation; Bylaws.  At the Effective
Time, the Certificate of Incorporation and Bylaws of Merger Sub, each as in
effect immediately prior to the Effective Time, shall be the Certificate of
Incorporation and Bylaws of the Surviving Corporation until thereafter amended
as provided by Nevada Law, the Certificate of Incorporation and the Bylaws.

    Section 1.07  Directors and Officers.  The directors of Merger Sub
immediately prior to the Effective Time shall be the initial directors of the
Surviving Corporation, each to hold office in accordance with the Certificate of
Incorporation and Bylaws of the Surviving Corporation, and the officers of
Merger Sub immediately prior to the Effective Time shall be the initial officers
of the Surviving Corporation, in each case until their respective successors are
duly elected or appointed and qualified.

                                       2

    Section 1.08  Conversion of Shares.  Subject to any adjustment to such
terms pursuant to Section 1.12, at the Effective Time, (a) each share of Common
Stock outstanding immediately prior to the Effective Time (other than any
Dissenting Shares (as hereinafter defined) and any shares of Common Stock held
by Acquiror) shall automatically and without any action on the part of the
holder thereof, upon surrender of the certificate that formally evidenced such
Common Stock in the manner provided herein, be cancelled and shall be converted
automatically into the right to receive an amount payable in cash, without
interest, determined by dividing the Adjusted VSP Consideration (as defined
below) by the number of shares of Common Stock outstanding immediately prior to
the Effective Time other than those held by Acquiror (such amount payable per
share in the Merger being referred to herein as the "Merger Consideration"), (b)
each share of Common Stock outstanding immediately prior to the Effective Time
held by Acquiror shall be cancelled for no consideration, and (c) each share of
common stock, $0.01 par value per share, of Acquiror shall be converted into one
share of common stock of the Surviving Corporation.  For the purposes of the
preceding sentence, "Adjusted VSP Consideration" shall mean the product obtained
by multiplying the VSP Consideration (as defined in Section 1.13) times the
percentage obtained by subtracting (i) the percentage of the Company's
outstanding Common Stock exchanged for Acquiror Class B Common Stock pursuant to
Section 5.09(a) (assuming, for the purpose of determining such percentage, that
all of Parent's Preferred Stock has been converted into Common Stock at the time
of such exchange) from (ii) 100 percent.

    Section 1.09  Stock Options.  

            (a)  Each stock option (and any related rights) to purchase capital
stock of any of the VSP Entities (as hereinafter defined) granted under stock
option plans of the VSP Entities outstanding prior to the consummation of the
Reorganization (as hereinafter defined) (each, a "VSP Entity Option") shall be
converted into a stock option to purchase shares of Class A Common Stock under
the Company's Stock Option Plans (the "Company Stock Option Plan") prior to the
Closing Date on the terms and conditions described in Schedule 2.05(b) pursuant
to the Reorganization (as hereinafter defined).

            (b)  Each stock option (and any related alternative rights) to
purchase one share of Common Stock (the "Stock Options") granted under the
Company's Stock Option Plan (including those granted to current or former
employees, consultants and directors of the Company or the VSP Entities and
including those stock options granted pursuant to Section 1.09(a) above), which
Stock Options are outstanding at the Effective Time (whether or not then
presently exercisable), other than those that will expire by their terms in
connection with or as a result of the Merger, will be converted at the Effective
Time into an option to purchase a number of shares of Acquiror Class B Common
Stock as would provide such optionholder the right to acquire substantially the
same percentage ownership of the capital stock of Acquiror immediately following
the Effective Time as such optionholders would have been entitled to acquire in
the Company immediately prior to the Effective Time at a price per share equal
to (i) the aggregate exercise price for the shares of Common Stock subject to
such Stock Option divided by (ii) the number of full shares of Acquiror Class B
Common Stock deemed purchasable pursuant to each such Stock Option issued
pursuant to this Section 1.08 (the "Option Consideration").  The Company Stock
Option Plan shall terminate as of the Effective Time and thereafter the only
rights of participants therein shall be the right to receive the consideration
set forth in this Section 1.09.  Prior to the Effective Time, the Company shall
use its reasonable efforts to cause each holder of outstanding Stock Options to
consent to the conversion of the Stock Options held by such holder in
consideration for the Option Consideration, and shall take such other action as
may be necessary to carry out the terms of this Section 1.09.

    Section 1.10   Dissenting Shares.  Notwithstanding any provision in this
Agreement to the contrary, to the extent that appraisal rights are available
under Nevada Law, Common Stock outstanding

                                       3


<PAGE>

immediately prior to the Effective Time and held by a holder who has not 
consented thereto in writing and who has demanded appraisal for such Common 
Stock in accordance with such law shall not be converted into or represent 
the right to receive the Merger Consideration, but shall be entitled to 
receive such consideration as shall be determined pursuant to Section 
92A.300, et. seq. of the Nevada Law, provided, however, that, if such holder 
shall have failed to perfect or shall have effectively withdrawn or lost his 
or her right to appraisal and payment under the Nevada Law, such holder's 
shares of Common Stock shall thereupon be deemed to have been converted into 
and to have become exchangeable for, as of the Effective Time, the right to 
receive the Merger Consideration, without any interest thereon, in accordance 
with Section 1.08, and such shares shall no longer be Dissenting Shares (the 
"Dissenting Shares").  The Company shall give Acquiror prompt notice of any 
demands received by the Company for appraisal of Common Stock, and Acquiror 
shall have the right to participate in all negotiations and proceedings with 
respect to such demands.  The Company shall not, except with the prior 
written consent of Acquiror, make any payment with respect to, or settle or 
offer to settle, any such demands.

    Section 1.11   Surrender of Common Stock and Stock Options.

            (a)  At the Closing, each Company stockholder of record shall 
deliver to Merger Sub a stock certificate ("Certificate") which, immediately 
prior to the Effective Time, represents all of such holders's shares of 
Common Stock, for conversion and exchange into the Merger Consideration 
pursuant to this Section 1.11.  At the Closing, Merger Sub shall deliver to 
each such stockholder who delivered his Certificate in exchange therefor an 
amount equal to the product of the Merger Consideration multiplied by the 
number of shares of Common Stock so surrendered by the holder thereof.  Each 
share of Common Stock so converted shall, by virtue of the Merger and without 
any action on the part of the holders thereof, cease to be outstanding, be 
cancelled and retired and cease to exist. In the event of a transfer of 
ownership of Common Stock which is not registered in the transfer records of 
the Company, the Merger Consideration may be delivered to a transferee if the 
Certificate representing such Common Stock is presented to the Acquiror and 
accompanied by all documents required to evidence and effect such transfer 
and to evidence that any applicable stock transfer taxes have been paid.  
Until surrendered as contemplated by this Section 1.11, each holder of a 
Certificate shall thereafter cease to possess any rights with respect to such 
Common Stock, except the right to receive upon such surrender the Merger 
Consideration as provided herein and by the provisions of Nevada Law.

            (b)  At the Closing, each holder of Stock Options shall deliver to
Merger Sub a stock option agreement or other agreement evidencing the grant of
Stock Option to the holder thereof (each an "Option Agreement") which, at the
Effective Time, represented all of such holder's Stock Options, for conversion
and exchange into the Option Consideration pursuant to this Section 1.11.  At
the Closing, Acquiror shall deliver, and Acquiror and each holder of a Stock
Option shall enter into, a stock option agreement, in form acceptable to
Acquiror, providing for the Option Consideration to be received by each such
optionholder (a "Replacement Option Agreement").  Following the Effective Time
and until the holder shall have executed and delivered a Replacement Option
Agreement and surrendered his or her Stock Options as contemplated by this
Section 1.11, each holder of a Stock Option shall cease to possess any rights
with respect to such Stock Option, except the right to receive upon such
surrender and execution the Option Consideration as provided herein and the
provisions of Nevada Law.

            (c)  All consideration delivered upon the surrender of the Common
Stock and Stock Options in accordance with the terms hereof to the former
stockholders and optionholders of the Company shall be deemed to have been
delivered in full satisfaction of all rights pertaining to such Common Stock and
Stock Options, respectively.  After the Effective Time, there shall be no
further registration of transfers on the stock transfer books of the Company of
the shares of Common Stock that were outstanding immediately prior to the
Effective Time, and the Company shall not issue any shares of

                                        4

<PAGE>

Common Stock upon the exercise of any Stock Options.  If, after the Effective 
Time, Certificates or Stock Options are presented for any reason, they shall 
be cancelled and exchanged as provided in this Section 1.11.

            (d)  In the event the Alternative Transaction is consummated, all
references in this Section 1.11 to Common Stock shall be interpreted to mean
references to Common Stock and Preferred Stock, and all references to Merger
Consideration shall be interpreted to mean the consideration to be received per
share of Common Stock and Preferred Stock in the Merger pursuant to
Section 1.12.

    Section 1.12   Alternative Transaction.

            (a)  In the event that the Closing shall not have occurred as of 
June 30, 1997 solely as a result of the failure of the condition to Closing 
contained in Section 8.08 to be satisfied, Acquiror, Acquiror II and Merger 
Sub may, at their sole option, elect to consummate the Merger and the VHI 
Acquisition notwithstanding the non-satisfaction of such condition subject to 
the following adjustments to the terms of the Merger and the VHI Acquisition 
(as so adjusted, the "Alternative Transaction"): (a) in the Merger, (i) all 
of the shares of Preferred Stock outstanding immediately prior to the 
Effective Time shall be converted in the aggregate into an amount, payable in 
cash without interest, equal to 65% of the VSP Consideration and (ii) all of 
the shares of Common Stock outstanding immediately prior to the Effective 
Time (other than any Dissenting Shares) shall be converted in the aggregate 
into a number of shares of Class B Common Stock of Acquiror as would 
represent substantially the same percentage ownership of the capital stock of 
Acquiror immediately following the Effective Time as the percentage such 
shares of Common Stock represented in the Company immediately prior to the 
Effective Time and (b) in the VHI Acquisition, Acquiror II shall acquire 65% 
of the outstanding capital stock of VHI owned by Parent in exchange for a 
payment in cash by Acquiror II of an amount equal to 65% of the VHI 
Consideration.

            (b)  If the Closing shall be effectuated as an Alternative 
Transaction pursuant to Section 1.12, Parent shall have the right to 
purchase, upon the issuance by the Acquiror of any of its equity securities 
("New Stock"), a pro rata portion of such New Stock such that Parent may 
maintain its percentage ownership in the capital stock of the Acquiror.  
Notwithstanding the foregoing, Parent shall have no preemptive rights with 
respect to the issuance of New Stock (i) pursuant to Acquiror's stock option 
plan, (ii) in the Merger and in the exchange transaction and as contemplated 
by Section 5.09, (iii) issuable upon the conversion or exercise of any 
securities outstanding on the date hereof, or (iv) issuable in connection 
with acquisitions that may be consummated by Acquiror or any of its 
subsidiaries.  The preemptive rights granted under this Section 1.12 shall 
expire upon the earlier to occur of (i) the date upon which Parent shall own 
capital stock of Acquiror representing less than 20% of the aggregate voting 
power with respect to matters generally requiring shareholder approval, and 
(ii) the date upon which upon an initial public offering of Acquiror's 
capital stock is consummated.  The terms of the preemptive rights granted 
hereunder shall be more specifically set forth in the securityholders 
agreement of Acquiror.

    Section 1.13   Consideration. The total of the consideration for the
Transaction (the consideration allocated to the Merger is hereinafter referred
to as the "VSP Consideration", and the consideration allocated to the VHI
Acquisition is hereinafter referred to as the "VHI Consideration") shall be
equal to $84,312,500.00 (the "Gross Consideration").  Between the date hereof
and the Closing, Acquiror and Acquiror II shall determine the allocation of the
Gross Consideration among the VSP Consideration and the VHI Consideration
(provided that Acquiror and Acquiror II shall not be entitled to allocate in
excess of $1,500,000 to the VHI consideration), and Acquiror and Acquiror II
shall notify the Company and Parent in writing of such determination not later
than five (5) days prior to the Closing.

                                       5

If, and to the extent that, all of the VSP Consideration is not paid to the 
stockholders of the Company pursuant to the provisions of Section 1.08, such 
unpaid portion shall be retained by Acquiror.

                            AND AGREEMENTS OF THE COMPANY

    The Company hereby represents, warrants and agrees with the Acquiror and
Merger Sub that, except as set forth on the Schedules attached hereto: 

    Section 2.01  Corporate Existence.  The Company is a corporation duly
organized, validly existing and in good standing under the laws of Nevada.  Each
of the entities listed on Schedule 2.01 is a corporation duly organized, validly
existing and in good standing under the laws of its jurisdiction of
incorporation (each, a "VSP Entity" and collectively, the "VSP Entities").  Each
of the Company and the VSP Entities has full corporate power to carry on its
business as now being conducted and to own and operate the property and assets
now owned and operated by it, and is duly qualified to transact business and is
in good standing in each jurisdiction where the ownership of its properties or
the conduct of its business requires such qualification and the failure to be so
qualified would have a material adverse effect on the business, operations,
properties or condition (financial or otherwise) of the Company and the VSP
Entities taken as a whole (a "Company Material Adverse Effect").  As used in
this Agreement, "to the Company's knowledge" means the actual knowledge of the
executive officers of the Company, without having made any independent
investigation in connection with the execution of this Agreement.

    Section 2.02  Corporate Power and Authority.  The Company has all
requisite corporate power and authority to execute and deliver this Agreement
and each other agreement, document, or instrument or certificate contemplated by
this Agreement to be executed by the Company in connection with the consummation
of the transactions contemplated hereby (together with this Agreement, the
"Company Documents"), and to consummate the transactions contemplated hereby and
thereby.  All corporate action necessary to authorize the execution, delivery
and performance of each of the Company Documents has been duly taken by the
Company.  This Agreement has been, and each of the Company Documents will be at
or prior to the Closing, duly and validly executed and delivered by the Company
and (assuming the due authorization, execution and delivery by the other parties
hereto and thereto) this Agreement constitutes, and each of the Company
Documents when so executed and delivered will constitute, legal, valid and
binding obligations of the Company, enforceable against the Company in
accordance with their respective terms, subject to applicable bankruptcy,
insolvency, reorganization, moratorium and similar laws affecting creditors'
rights and remedies generally, and subject, as to enforceability, to general
principles of equity, including principles of commercial reasonableness, good
faith and fair dealing (regardless of whether enforcement is sought in a
proceeding at law or in equity).

    Section 2.03  Reorganization.  Each of the Company and the VSP Entities
has all requisite corporate power and authority to consummate the Reorganization
(as hereinafter defined) and to execute and deliver each of the agreements,
documents, instruments or certificates contemplated by the Reorganization or be
executed by the Company or any of the VSP Entities in connection with the
Reorganization (the "Reorganization Documents"), and to consummate the
transactions contemplated thereby.  All corporate action necessary to authorize
the execution, delivery and performance of each of the Reorganization Documents
has been duly taken by each of the Company and the VSP Entities.  The
Reorganization Documents have been duly and validly executed and delivered by
each of the Company and VSP Entities (assuming the due authorization, execution
and delivery by the other parties thereto) and constitute legal, valid and
binding obligations of each of the Company and the VSP Entities,

                                       6


<PAGE>

enforceable against each of the Company and the VSP Entities in accordance 
with their respective terms, subject to applicable bankruptcy, insolvency, 
reorganization, moratorium and similar laws affecting creditors' rights and 
remedies generally, and subject, as to enforceability, to general principles 
of equity, including principles of commercial reasonableness, good faith and 
fair dealing (regardless of whether enforcement is sought in a proceeding at 
law or in equity).

    Section 2.04  Conflicts.  None of the execution and delivery by the
Company of this Agreement and the other Company Documents, the consummation of
the transactions contemplated hereby or thereby, including, without limitation,
the Reorganization (as hereinafter defined), or compliance by the Company and
the VSP Entities with any of the provisions hereof or thereof will (i) violate
any provision of the certificate of incorporation or by-laws of the Company or
the VSP Entities; (ii) conflict with, violate, result in the breach or
termination of, or constitute a default under any note, bond, mortgage,
indenture, license, agreement or other instrument or obligation to which the
Company or any VSP Entity is a party or by which its properties or assets are
bound; (iii) violate any statute, rule, regulation, order or decree of any
governmental body or authority by which the Company or any VSP Entity is bound;
or (iv) result in the creation of any lien, pledge, mortgage, deed of trust,
security interest, claim, lease, charge, encumbrance or any other restriction or
limitation whatsoever upon the properties or assets of the Company or any VSP
Entity except, in case of clauses (ii), (iii) and (iv), for such conflicts,
violations, breaches or defaults as would not have a Company Material Adverse
Effect.

    Section 2.05  Capitalization.  (a)  The authorized capital stock of the
Company consists of 80,000,000 shares of Preferred Stock, $0.01 per share (the
"Preferred Stock"), 100,000,000 shares of Class B Common Stock and
20,000,000 shares of Class A Common Stock.  The issued and outstanding shares of
Preferred Stock, Class A Common Stock and Class B Common Stock (such issued
shares are collectively referred to herein as the "Capital Stock"), as of the
date hereof and as adjusted to give effect to the Reorganization (as hereinafter
defined), are as set forth on Schedule 2.05(a).  All of the shares of Capital
Stock have been duly authorized and validly issued and are fully paid and
nonassessable.  Except as set forth in Schedule 2.05(b) hereto or as
contemplated herein, there are no subscriptions, options, warrants, conversion
rights, rights of exchange, or other rights, plans, agreements or commitments of
any nature whatsoever (including, without limitation, conversion or preemptive
rights) providing for the purchase, issuance, transaction, registration or sale
of any shares of the Company's Capital Stock or any securities convertible into
or exchangeable for any shares of the Company's Capital Stock (collectively, the
"Company Derivative Securities").  None of the Company Derivative Securities are
entitled to be accelerated as a result of the Merger.  All of the Company
Derivative Securities have been issued, and all of the Company Derivative
Securities to be issued in the Reorganization will be issued, pursuant to valid
exemptions from registration under all Federal and state securities laws, except
where the failure to have such exemptions would not have a Company Material
Adverse Affect, and there are no outstanding obligations of the Company to
repurchase, redeem or otherwise acquire any of the Company Derivative
Securities.

            (b)  The authorized and outstanding capital stock of each VSP 
Entity, as of the date hereof and as adjusted to give effect to the 
Reorganization (as hereinafter defined), is as set forth on Schedule 2.05(c) 
hereto (such issued shares are collectively referred to as the "VSP Entities' 
Capital Stock").  All such shares of VSP Entities' Capital Stock have been 
duly authorized and validly issued and are fully paid and nonassessable.  
Except as set forth on Schedules 2.05(b) or 2.05(d) hereto or as contemplated 
herein, there are no subscriptions, options, warrants, concession rights, 
rights of exchange, or other rights, plans, agreements or commitments of any 
nature whatsoever (including, without limitation, conversion or preemptive 
rights) providing for the purchase, issuance, transaction, registration or 
sale of any shares of VSP Entities' Capital Stock or any securities 
convertible into, or exchangeable for, any shares of VSP Entities' Capital 
Stock (the "VSP Entity Derivative Securities").  None of the VSP

                                       7

<PAGE>

Entity Derivative Securities are entitled to be accelerated as a result of 
the Merger.  All of the VSP Derivative Securities have been issued, and all 
of the VSP Derivative Securities, if any, to be issued in the Reorganization 
will be issued, pursuant to valid exemptions from registration under all 
Federal and State securities laws, except where the failure to have such 
exemption would not have a Company Material Adverse Effect, and there are no 
outstanding obligations of any of the VSP Entities or the Company to 
repurchase, redeem or otherwise acquire any of the VSP Derivative Securities.

    Section 2.06  Financial Statements.  The Company has furnished the
Acquiror with an audited (based upon agreed upon procedures) balance sheet and
related statement of income for the Company at and for the fiscal year ended
November 30, 1996 (collectively, the "November Financial Statements").  The
Company has also furnished the Acquiror with the unaudited balance sheet as of
February 28, 1997, pro forma to give effect to the separation of (i) the Parent,
on the one hand, and (ii) the Company and VSP Entities, on the other hand, and
the Reorganization (the "February 28 Balance Sheet" and, collectively with the

on Schedule 2.06, the Financial Statements (i) have been prepared from the books
and records of the Company in accordance with accounting practices consistently
applied with prior periods, (ii) are complete and correct in all material
respects and fairly present the financial condition and results of operations,
as applicable, of the Company as of the dates and for the periods indicated
thereon, and (iii) to the Company's knowledge, contain and reflect adequate
reserves for all liabilities or obligations of any nature, whether absolute,
contingent or otherwise, as may be required under generally accepted accounting
principles.  To the Company's knowledge, neither the Company nor any of the VSP
Entities has any liability that is not reflected in the February 28 Balance
Sheet, other than liabilities incurred in the ordinary course of business since
the date of the February 28 Balance Sheet.

    Section 2.07  Properties.  The following Schedules set forth the
information indicated as of the dates noted on such Schedules:

            (a)  Schedule 2.07(a) sets forth a list of all of the interests in

Thousand Dollars ($100,000.00).

    Each of the Company and the VSP Entities has good and marketable title to 
all Real Property and Personal Property listed on Schedules 2.07(a) and

Personal Property listed on such Schedules as leased by each of  the Company 
and the VSP Entities, except such as shall have been disposed of in the 
ordinary course of business since the date of such Schedules.  To the 
Company's knowledge, such properties and assets are subject to no liens, 
mortgages, pledges, encumbrances or charges of any kind except liens for real 
property taxes not delinquent or being contested in good faith and for which 
adequate provision has been made, statutory mechanics and materialman's 
liens, liens and encumbrances disclosed on the public record, or which would 
not have a Company Material Adverse Effect. 

    Section 2.08  Subsidiaries and Partnerships.  Except as set forth on

subsidiaries or investments in other corporations, partnerships or joint

and does not have a term extending beyond twelve months from the date of this
Agreement; and (iii) any contract pursuant to which a physician provides

(collectively, the "Material Contracts").  Schedule 2.09 also identifies all
contracts of the Company in which its officers or directors (or any person, firm
or corporation affiliated with such persons, excluding any contracts with
Parent) have a material interest.  Except as would not individually or in the
aggregate, have a Company Material Adverse Effect, each Material Contract and
each Physician Contract is a legal, valid and binding agreement, and none of the

or agreements of any kind with respect to the Proprietary Rights except those
that would not have a Company Material Adverse Effect.  Except as disclosed on
Schedule 2.10, the Company has not been informed of any claims or suits pending
or threatened against the Company or any of the VSP Entities claiming an
infringement by the Company or any of the VSP Entities of any patents,
copyrights, licenses, trademarks, service marks or trade names of others.

(and as of the Closing will have rights to use), all of the assets and property,
both tangible and intangible, necessary for the operation of the businesses of
the Company and the VSP Entities as currently conducted, except where the
failure to own or have such rights would not have a Company Material Adverse
Effect.

    Section 2.12   Compliance With Laws.  To the knowledge of the Company, each
of the Company and the VSP Entities is in compliance with all applicable laws,
regulations, orders, judgments, ordinances or decrees of any Federal, state or
local court or any governmental authority, the non-compliance with which would
have a Company Material Adverse Effect.

    Section 2.13   Litigation.  There is no litigation, proceeding or
controversy pending or, to the Company's knowledge, threatened, by or against
the Company or the VSP Entities before any court, government agency or any other
administrative body that would reasonably be expected to have a Company Material
Adverse Effect or prohibit or restrain the ability of the Company to enter into
this Agreement or to consummate the transactions contemplated hereby.

    Section 2.14   Labor Matters.  Schedule 2.14 lists the collective
bargaining agreements or other labor union contracts and employee benefit plans
applicable to employees which are employed by the Company or any of the VSP
Entities, and, to the Company's knowledge, the Company and the VSP Entities are
as of the date of this Agreement in full compliance with the terms and
conditions of such agreements and contracts, except where the failure to be in
compliance would not have a Company Material Adverse Effect.  Except as set
forth on Schedule 2.14, and to the Company's knowledge, (i) there are no charges
or allegations of unfair labor practices pending or threatened under Federal or
state labor laws; (ii) there are no pending arbitration matters or grievance
procedures under any of the

                                       9

existing which upon the giving of notice, or lapse of time, will result in a 
breach under any collective bargaining agreement or under any of the other 
foregoing agreements, which would have a Company Material Adverse Effect; and 
(iv) there is no pending or threatened labor dispute, strike or work stoppage 
which would have a Company Material Adverse Effect.

    Section 2.15   Absence of Certain Changes.  Except for the Reorganization
and except as disclosed on Schedule 2.15 hereto, since November 30, 1996, each
of the Company and the VSP Entities has operated its business only in the
ordinary course and there has not occurred:

            (a)  Any event that has had a Company Material Adverse Effect;

            (b)  Any declaration or payment of any dividends or distributions by
the Company or the VSP Entities, any acquisition or redemption by the Company or
the VSP Entities of any of its or their equity securities or any loan by the

this Agreement by the Company will not, require any consent, approval,
authorization or permit of, or filing with or notification to, any governmental
or regulatory authority, domestic or foreign, except (i) for applicable
requirements, if any, of the pre-merger notification requirements of the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the rules
and regulations thereunder (the "HSR Act") and filing and recordation of
appropriate merger documents as required by Nevada Law and Delaware Law and (ii)
where the failure to obtain such consents, approvals, authorizations or permits,
or to make such filings or notifications, would not prevent or delay
consummation of the Merger or otherwise prevent the Company from performing its
obligations under this Agreement, and would not, individually or in the
aggregate, have a Company Material Adverse Effect.  The execution and delivery
of the transactions and documents contemplated by the Reorganization (as
hereinafter defined) do not require any consent, approval, authorization or
permit of, or filing with or notification to, any governmental or regulatory
authority, domestic or authority except (i) as where such consents, approvals,
authorizations or permits have been obtained, or such filings or notifications
have been made or (ii) where the failure to obtain such consents, approvals,

the Company to be converted into Class B Common Stock on the terms and

aggregate voting power of all outstanding shares of capital stock of the Company
with respect to the election of directors of the Company immediately prior to
the Effective Time.

    Section 5.11   Employee Benefits Matters.  Parent and the Company shall

Closing; (ii) the royalty free license by the Company to Parent of the right 
to use the name "Vivra" in connection with the operation of Parent's business

immediately cease the promotion of the names "Vivra Renal Care" and "Vivra"

    The parties covenant that:

tariffs, imposts, and other charges of any kind (together with any and all
interest, penalties, additions to tax and additional amounts imposed with
respect thereto) imposed by any government or taxing authority, including,

    Section 6.02  Tax Allocation.

            (a)  Parent shall pay, and be liable for, any and all Taxes for 
which the Company or any of the VSP Entities may become liable with respect 
to (i) all periods ending on or prior to the Closing Date and (ii) any 
Pre-Closing Partial Period (hereinafter, any and all such Taxes referred to 
as "Parent's Potential Tax Liability"); provided, however, that Parent's 
Potential Tax Liability shall not include (i) any such Taxes to the extent 
there is a reserve established therefor as of the Closing Date, and (ii) any 
Taxes relating to any activities or transactions occurring on the Closing 
Date, but after the Closing, imposed on the Company or any of the VSP 
Entities that are not in the ordinary course of business.  Parent's Potential 
Tax Liability shall include but not be limited to any Tax liability arising 
pursuant to the federal consolidated return rules, including the deferred 
income rules under Treas. Reg Section 1.1502-13 and Section 1.1502-14, the 
excess loss account rules under Treas. Reg Section 1.1502-19 and any Tax 
asserted under Treas. Reg. Section 1.1502-6. Notwithstanding anything to the 
contrary above, Parent's Potential Tax Liability shall not include any 
liability for Taxes owing as a result of any deemed sale of assets pursuant 
to Section 338 (or any corresponding rules under state, local, or other Tax 
laws) with respect to the Company or any of the VSP Entities to the extent 
such Taxes exceed the Tax liability that Parent would have incurred upon the 
Transactions or the Alternate Transaction in the absence of such deemed sale 
of assets pursuant to Section 338.

            (b)  Acquiror shall pay, and be liable for, any and all Taxes 
imposed on or allocable to the Company or any of the VSP Entities with 
respect to the operations, business, activities or assets of the Company and 
the VSP Entities for which Parent is not liable pursuant to the provisions of 
Section 6.02(a) (hereinafter, any and all such Taxes referred to as 
"Acquiror's Potential Tax Liability").

            (c)  Any Taxes for any period that begins before and ends after the
Closing Date and that are imposed on a periodic basis with respect to the assets
of the Company or any VSP Entity, or otherwise measured by the level of any
item, shall be apportioned between the Post-Closing Period and the Pre-Closing
Period by taking the amount of such Taxes for the entire period (or, in the case
of such Taxes determined on an arrears basis the amount of such Taxes for the
immediately preceding period), multiplied by a fraction the numerator of which
is the number of calendar days in the period ending on the Closing Date and the
denominator of which is the number of calendar days in the entire period.  No
election under Treas. Reg Section 1.1502-76(b)(2)(ii)(D) (dealing with a
pro-rata allocation) shall be made in connection with the Transactions.

            (d)  Parent shall not change its current policies and practices with
respect to the sharing of Taxes within its affiliated group until the Closing
Date.  All Tax sharing agreements or similar agreements with respect to or
involving the Company or any of the VSP Entities shall be terminated as of the
Closing Date and, after the Closing Date, the Company and the VSP Entities shall
not be bound thereby or have any liability thereunder.

    Section 6.03  Tax Indemnity.

            (a)  Parent shall indemnify, save and hold harmless Acquiror, Merger
Sub and the Company, all of the VSP Entities and each of their respective
subsidiaries, affiliates, directors, stockholders, officers, employees, agents,
consultants, successors, transferees and assignees and their respective
representatives from and against any and all losses incurred in connection with,
arising out of, resulting from or relating to any Parent's Potential Tax
Liability.

            (b)  Acquiror shall indemnify, save and hold harmless Parent and 
each of its respective subsidiaries, affiliates, directors, stockholders, 
officers, employees, agents, consultants, successors, transferees and 
assignees and their respective representatives from and against any and all 
losses incurred in connection with, arising out of, resulting from or 
relating to any Acquiror's Potential Tax Liability.

            (c)  Parent shall promptly pay to Acquiror (or other indemnitee) 
after receipt of notice from Acquiror or other indemnitee (together with 
appropriate calculations), and after a final determination of the amount of 
any Taxes paid or to be paid by Acquiror (or other indemnitee) for which 
Parent is liable under Section 6.03(a), an amount equal to such Taxes.

            (d)  Acquiror shall promptly pay to Parent (or other indemnitee) 
after receipt of notice from Parent or other indemnitee (together with 
appropriate calculations), and after a final determination of the amount of 
any Taxes paid or to be paid by Parent (or other indemnitee) for which 
Acquiror is liable under Section 6.03(b), an amount equal to such Taxes.

    Section 6.04  Filing of Tax Returns.

            (a)  Parent shall file, on behalf of the group for which Parent 
is the common parent, all federal consolidated Tax returns and any state or 
local consolidated or combined Tax returns which have not been filed by the 
Closing Date and which Tax returns properly include the Company or any VSP 
Entity in Parent's consolidated or combined group.  Parent will include the 
income of the Company and such includable VSP Entities on such Tax returns 
for all periods through the Closing Date and pay any Taxes attributable to 
such income. Acquiror shall provide Parent with funds to make such payments 
to the extent required by Sections 6.03(b) and 6.09.  If there is any 
material change in the manner in which such Tax returns are prepared and if 
such material change has any adverse impact on the Company for periods (or 
portions thereof) after the Closing Date, such material change shall be 
subject to Acquiror's review and consent.  Parent shall also file all other 
Tax returns that have not been filed as of the Closing Date that are for any 
Taxable periods ending on or before the Closing Date.

            (b)  Except as provided by Section 6.04(a), Acquiror shall cause the
Company to prepare and file Tax returns with respect to Taxes which are required
to be filed by the Company that are for periods after the Closing Date
(excluding any federal consolidated returns and any state or local consolidated
or combined Tax returns to be filed by Parent on behalf of the group for which
Parent is the common parent and which return properly includes the Company or
any of the VSP Entities.)  All Tax returns for any Taxable periods that include
the Closing Date shall be prepared in a manner consistent with the Company's
prior practice (including elections), unless otherwise required by law,
provided, however, that Parent shall control the contents of the Tax returns to
the extent they relate to periods prior to the Closing Date or Pre-Closing
Partial Periods.  Acquiror shall provide Parent with copies of such Tax returns
at least 20 days prior to the due date thereof for Parent's review.

    Section 6.05  Control of Audits.

            (a)  Upon receipt by Acquiror or the Company of any notice or other
communication that there are any pending or threatened Tax audits or assessments
against the Company or any of the VSP Entities involving a Parent's Potential
Tax Liability, Acquiror shall promptly give written notice thereof to Parent.

                                       18


<PAGE>

            (b)  Subject to paragraph (d) of this Section 6.05, Parent shall 
have the sole right, exercisable at any time, to elect to represent the 
Company's interest or the interest of any of the VSP Entities in any Tax 
audit or administrative or court proceeding relating to Parent's Potential 
Tax Liability, to employ counsel of its choice at its expense, and to control 
the conduct of such audit or proceeding, including settlement or other 
disposition thereof.  If Parent elects to so represent the Company's interest 
or the interest of any of the VSP Entities, it shall notify Acquiror of its 
intent to do so, and shall reasonably and in good faith consult with Acquiror 
with respect to the defense against or compromise of any such Parent's 
Potential Tax Liability.

            (c)  If Parent elects not to represent the Company's interests or 
the interest of any of the VSP Entities pursuant to paragraph (b) of this 
Section 6.05, Acquiror shall, at the request of Parent, cause the Company to 
defend against such Parent's Potential Tax Liabilities and shall keep Parent 
fully advised of the process of such defense, it being understood that Parent 
shall not be excused from its obligations to pay Parent's Potential Tax 
Liabilities by reason of such election.  If Parent notifies Acquiror of 
Parent's desire to further contest the Parent's Potential Tax Liability, 
Parent shall be entitled to do so at Parent's expense by way of petition in 
the United States Tax Court, claim for refund, suit for refund, appeals, writ 
of certiorari or other procedures permitted under federal, state, local or 
foreign law.

            (d)  Notwithstanding paragraphs (b) and (c) of this Section 6.05,
Parent may not settle, compromise, or otherwise dispose of any such Parent's
Potential Tax Liability without the consent of Acquiror (which consent shall not
be unreasonably withheld), if such settlement, compromise, or other disposition
could have a material adverse effect on the Tax liabilities of the Company, the
VSP Entities or Acquiror for any period (or a portion thereof) after the
Closing.

    Section 6.06  Cooperation.  Parent and Acquiror agree to furnish or cause
to be furnished to each other, at no cost and upon request, as promptly as
practicable, such information and assistance (including access to books and
records) relating to the Company and the VSP Entities as are reasonably
necessary for preparation of any return, claim for refund or audit, and the
prosecution or defense of any claim, suit or proceeding relating to any Parent's
Potential Tax Liability.  Acquiror shall execute or cause to be executed and
deliver or cause to be delivered any powers of attorney and other documents
reasonably necessary to enable Parent (or its advisors) to take all actions in
connection with audits which Parent has right to control pursuant to Article 6
hereof.

    Section 6.07  Tax Refund.  Parent shall be entitled to retain, and
Acquiror or the Company shall pay to Parent within 10 days after the receipt,
any refund of Taxes or credit relating to the Company or any VSP Entity with
respect to a period ending on or prior to the Closing Date or a Pre-Closing
Partial Period.

    Section 6.08  Effect of Payment.  An indemnity payment by Parent pursuant
to this Article shall be treated as a reduction in the Merger Consideration.

    Section 6.09  Tax Elections.

            (a)  At Acquiror's election, Acquiror and Parent agree to make the
election provided for by Section 338(h)(10) of the Code (and any corresponding
election or deemed election under state, local or foreign Tax law)
(collectively, the "Election") with respect to the Company or the other VSP
Entities and to provide one another with all necessary information to permit the
Election to be made.  Parent and Acquiror shall, as promptly as practicable
following the Closing Date, take all actions necessary and appropriate
(including filing such form, returns, elections, schedules and other documents
as may be required) to effect and preserve a timely Election.

                                      19


<PAGE>

            (b)  In connection with any Election, prior to the due date for such
Election, Parent and Acquiror shall act together in good faith to (i) determine
and agree upon the amount of the "adjusted grossed-up basis" of assets of the
Company or any of the VSP Entities subject to the Election (within the meaning
of Treas. Reg. Section 1.338(h)(10)-1(e)(5)) and (ii) agree upon the proper
allocations (the "Allocations") of such "adjusted grossed-up basis" among the
assets of the Company in accordance with Section 338(b)(5) of the Code and the
Treasury regulations promulgated thereunder.  Parent and Acquiror shall not, and
Acquiror shall cause the Company, and the other VSP Entities, not to, take any
position inconsistent with the Allocations in any Tax return or otherwise.

            (c)  The parties agree that any and all Taxes payable by Parent
arising from the deemed sale of assets pursuant to Section 338 or otherwise of
the Code with respect to the Company or any of the VSP Entities (or any
corresponding election or deemed election under state, local, or foreign Tax
law), to the extent such Taxes exceed the Tax liability that Parent would have
incurred upon the Transactions in the absence of such Election, shall be borne
by Acquiror.  Acquiror shall pay to Parent, within ten (10) days after receipt
of notice from Parent (together with appropriate calculations), an amount equal
to the amount of any Taxes paid or to be paid by Parent for which Acquiror is
liable under the preceding sentence of this Section 6.09(c), together with any
Taxes paid or to be paid by Parent on amounts payable under this

                                      23


<PAGE>

arising under the agreements set forth on Schedule 9.01, other than those

of written notice of any claim, demand or assessment, or the commencement of any
suit, action or proceeding in respect of which indemnity may be sought on
account Section 9.01 or 9.02 of this Agreement, the party seeking
indemnification (the "Indemnitee") shall promptly, but in no event later than
twenty (20) days prior to the date a response or answer thereto is due (unless a
response or answer is due within fewer than twenty (20) days from the date the
Indemnitee's receipt of notice thereof), inform the party against whom
indemnification is sought (the "Indemnitor") in writing thereof.  The failure,
refusal or neglect of such Indemnitee to notify the Indemnitor within the time
period specified above of any such claim or action shall relieve such Indemnitor
from any liability which it may have to such Indemnitee in connection therewith,
if the effect of such failure, refusal or neglect is to prejudice materially the
rights of the Indemnitor in defending against the claim or action.  In case any
claim, demand or assessment shall be asserted or any suit, action or proceeding
is commenced against an Indemnitee, and such Indemnitee shall have timely and
property notified the Indemnitor of the commencement thereof, the Indemnitor
will be entitled to participate therein, and, to the extent that it may wish, to
assume the defense, conduct or settlement thereof, with counsel selected by the
Indemnitor.  After notice from the Indemnitor to the Indemnitee of its election
to assume the defense, conduct or settlement thereof, the Indemnitor will not be
liable to the Indemnitee for expenses incurred in connection with the defense,
conduct or settlement thereof, except for such expenses as may be reasonably
required to enable the Indemnitor to take over such defense, conduct or
settlement.  The Indemnitee will at its own expense cooperate with the
Indemnitor in connection with any such claim, make personnel, witnesses, books
and records relevant to the claim available to the Indemnitor at no cost, and
grant such authorizations or powers of attorney to the agents, representatives
and counsel of the Indemnitor as the Indemnitor may reasonably request in
connection with the defense or settlement of any such claim; provided that,
before settling any claim hereunder, the Indemnitor shall give ten (10) days
notice to the Indemnitee to provide the Indemnitee with the opportunity to
reject the settlement, and in the case of any rejection of any settlement that
would have released Indemnitee of any liability, Indemnitee shall thereafter
defend the claim at its own expense.  In the event that the Indemnitor does not
wish to assume the defense, conduct or settlement of any claim, demand or
assessment, the Indemnitee shall have the exclusive right to prosecute, defend,
compromise, settle or pay the claim in its sole discretion and pursue its rights
under this Agreement; provided that, before settling any claim hereunder, the
Indemnitee shall give ten (10) days' notice to the Indemnitor to provide the
Indemnitor with the opportunity to reject the settlement, and in the case of any
rejection of any settlement that would have released Indemnitor of any
liability, Indemnitor shall thereafter, at Indemnitee's election, defend the
claim at Indemnitor's own expense.  Notwithstanding the foregoing, the
Indemnitee shall have the right to employ separate counsel in any such action,
claim or proceeding and to participate in the defense thereof, but the fees and
expense of such counsel shall be paid by the Indemnitee unless (a) the
Indemnitor has agreed in writing to pay such fees and expenses, (b) the

                                       23


<PAGE>

Indemnitor has failed to assume the defense of such action, claim or proceeding
or (c) the named parties to any such action, claim or proceeding (including any
impleaded parties) include both the Indemnitor and the Indemnitee and the
Indemnitee reasonably determines that there may be one or more legal defenses
available to it which are different from or additional to those available to the
Indemnitor (in which case, if Indemnitee informs the Indemnitor in writing that
it elects to employ separate counsel at the expense of the Indemnitor, the
Indemnitor shall not have the right to assume the defense of such action, claim
or proceeding on behalf of the Indemnitee, it being understood, however, that
the Indemnitor shall not, in connection with any one such action, claim or
proceeding or separate but substantially similar or related actions, claims or
proceeding in the same jurisdiction arising out of the same general allegations
or circumstances, be liable for the reasonable fees and expenses of more than
one separate firm of attorneys at any time for the Indemnitee, which firm shall
be designated in writing by the Indemnitee).

    Section 9.04  Survival of Indemnification.  The right to make a claim for
indemnification pursuant to Sections 9.01 and 9.02 of this Agreement shall
survive the Closing Date until the fifth anniversary of the Closing Date. 
Further, the provisions of this Article VIII are intended to be for the benefit
of, and shall be enforceable by and binding on, each indemnified party and their
respective successors and assigns.
