         SECTION 2.02      ASSIGNABILITY AND CONSENTS.

         Notwithstanding anything to the contrary contained in this Agreement,
if the sale, assignment, transfer, conveyance or delivery or attempted sale,
assignment, transfer, conveyance or delivery to Buyer of any asset that would be
a Purchased Asset is (a) prohibited by any applicable Law or (b) would require
any authorizations, approvals, consents or waivers from a third Person or

consents or waivers shall not have been obtained prior to the Closing, then in
either case the Closing shall proceed without the sale, assignment, transfer,
conveyance or delivery of such asset and this Agreement shall not constitute a
sale, assignment, transfer, conveyance or delivery of such asset; provided that
nothing in this Section 2.02 shall be deemed to waive the rights of Buyer not to
consummate the transactions contemplated by this Agreement if the conditions to
its obligations set forth in Article X have not been satisfied. Subject to
Section 8.02, in the event that the Closing proceeds without the sale,
assignment, transfer, conveyance or delivery of any such asset, then following

waivers; provided, however, that Seller shall not be required to pay any
consideration to obtain any such authorization, approval, consent or waiver.

waiver, the parties shall cooperate with each other in any mutually agreeable,
reasonable and lawful arrangements designed to provide to Buyer the benefits of
use of such asset and to Seller the benefits, including any indemnities, that,
in each case, it would have obtained had the asset been conveyed to Buyer at the

Section 2.02 of any Assumed Contract, Buyer shall (x) perform for the benefit of
the other parties thereto the obligations of Seller or any Affiliate of Seller
thereunder, including any payments to be made thereunder; and (y) shall satisfy
any related Liabilities with respect to such Assumed Contract that, but for the
lack of an authorization, approval, consent or waiver to assign such obligations
or Liabilities to Buyer, would be Assumed Liabilities. If authorization,
approval, consent or waiver for the sale, assignment, transfer, conveyance or
delivery of any such asset not sold, assigned, transferred, conveyed or
delivered at the Closing is obtained, Seller shall assign, transfer, convey and
deliver such asset to Buyer at no additional cost to Buyer.

technology, analytical methods, and any other information in the possession of
Seller or its Affiliates that is reasonably required by Buyer or its designee
for the successful completion of such technology transfer; provided, however,
that the amount of time Seller is required to spend on such transfer of

a manner and intensity of effort consistent with the distribution activities of
Seller and its Affiliates during the calendar year 2000, and in accordance with

Seller) for Products distributed following the Closing.

         SECTION 8.18      REGULATORY TRANSITION BY SELLER.

         During a transitional period of up to 50 days following the Closing (or

compliance activities after such initial 50-day period, then for a maximum of an
additional 40 days, Seller shall continue to carry them out and Buyer shall
reimburse Seller for its personnel's time at $200 per hour per professional or
technical employee. Except as set forth in the previous sentence, all costs and
expenses for such regulatory transition services will be the responsibility of

take all other actions required by, applicable Governmental or Regulatory
Authorities that are necessary to permit Seller to perform its obligations under
this Section 8.18.

         SECTION 8.19      REFORMULATION OF MVI-12 PRODUCT.

         (a)      Seller shall use its commercially reasonable efforts to
         reformulate the MVI-12 Product in a commercially salable drug product
         pursuant to the Federal Register Notice published by the FDA on April
         20, 2000 [Docket No. 79N-0113] and obtain FDA approval of the
         Reformulation SNDA on behalf of Buyer ("Seller's Reformulation
         Efforts"); provided that Seller has the absolute right at any time to
         abandon its Reformulation Efforts after September 30, 2002 by providing
         written notice to Buyer, whereupon Buyer shall then have no obligation
         to pay the Remaining Purchase Price to Seller.

         (b)      Upon the earlier of FDA's approval of the Reformulation SNDA
         or Seller's notice to Buyer that it is abandoning its efforts to obtain
         such approval, Seller shall deliver to Buyer all books and records
         relating to the reformulation of the MVI-12 Product and Seller shall
         grant to Buyer an irrevocable, exclusive, worldwide, royalty-free,
         fully paid up, perpetual license, with right to sublicense or assign,
         to use, import or practice, solely in connection with the development,
         manufacture, having manufactured, use, marketing and selling injectable
         multivitamin pharmaceutical products ("Injectable Multivitamin
         Pharmaceutical Field"), any patent or patentable invention created or
         used, or Know-How developed, obtained or used, by Seller in the course
         of performing the reformulation services described in the previous
         sentence ("Reformulation Intellectual Property"). A license under this
         Section 8.19 is a "Reformulation Intellectual Property License."

                  (i)      Seller's Reformulation Intellectual Property License
                           is limited to the Injectable Multivitamin
                           Pharmaceutical Field and in no circumstance extends
                           beyond that Field. Seller retains all right to make,
                           use, sell and offer for sale Reformulation
                           Intellectual Property outside of the Injectable
                           Multivitamin Pharmaceutical Field, including the
                           right to exclude Buyer from making, using, selling
                           and offering for sale outside the Injectable
                           Multivitamin Pharmaceutical Field.

<PAGE>

                  (ii)     Seller's obligation to grant Buyer a Reformulation
                           Intellectual Property License is limited to the
                           extent of its own rights to Reformulation
                           Intellectual Property, and in no way creates an
                           obligation in Seller to seek or obtain permission or
                           rights from any third party for granting Buyer a
                           Reformulation Intellectual Property License. From the
                           date hereof, Seller shall use its commercially
                           reasonable efforts to not take any action that would
                           limit its own rights to Reformulation Intellectual
                           Property, or limit Seller's ability to grant a
                           Reformulation Intellectual Property License to Buyer.

                  (iii)    There is no requirement that Reformulation
                           Intellectual Property result from Seller's
                           Reformulation Efforts, and Buyer expressly recognizes
                           that no Reformulation Intellectual Property may
                           result from Seller's Reformulation Efforts. Seller
                           has no obligation to seek or obtain intellectual
                           property protection for Know-How created, used or
                           obtained by Seller in the course of Seller's
                           Reformulation Efforts (although Seller will keep all
                           such Know-How, to the extent relating to the
                           Injectable Multivitamin Pharmaceutical Field,
                           confidential), and Seller retains the sole right and
                           discretion to determine whether and how to seek,
                           apply for, pursue, obtain, maintain or defend
                           intellectual property protection for any such
                           Know-How and for Reformulation Intellectual Property.
                           Notwithstanding the foregoing, if Seller (1)
                           identifies potentially patentable subject matter
                           relating to the Injectable Multivitamin
                           Pharmaceutical Field and (2) determines not to seek
                           patent protection for such subject matter, then
                           Seller shall so notify Buyer within 60 days of such
                           identification. Buyer shall then have the right and
                           discretion to seek patent protection for such subject
                           matter at Buyer's sole cost and expense, and Buyer
                           shall own any subsequently issuing patents. Seller
                           shall have no responsibility whatsoever for the
                           patent prosecution or the maintenance or protection
                           of any subsequently issuing patent rights.



                  (iv)     Indemnification by Buyer to Seller for Buyer's use or
                           practice of Reformulation Intellectual Property is
                           governed by Section 11.02.



                  (v)      Seller makes no representations or warranties with
                           respect to Reformulation Intellectual Property,
                           including that any Reformulation Intellectual
                           Property is valid or enforceable, or that Buyer's use
                           or practice any Reformulation Intellectual Property
                           will not infringe the intellectual property rights or
                           any other rights of any third party, or that Seller
                           owns all right, title and interest in

                           and to, or has a license, sublicense or other
                           permission to use, Reformulation Intellectual
                           Property.

                  (vi)     Seller has the sole and exclusive right and
                           discretion to determine whether and how to enforce
                           Reformulation Intellectual Property, and whether to
                           commence, maintain or terminate, whether by
                           settlement or otherwise, any litigation, action or
                           proceeding regarding Reformulation Intellectual
                           Property ("Reformulation Intellectual Property
                           Litigation"); provided, however, that in no event
                           shall Seller settle Reformulation Intellectual
                           Property Litigation on terms which eliminate Buyer's
                           exclusivity under the Reformulation Intellectual
                           Property License. Seller shall give Buyer no less
                           than 20 days notice prior to settling any
                           Reformulation Intellectual Property Litigation
                           commenced pursuant to this subparagraph (vi) and the
                           opportunity to reasonably object to the terms of such
                           settlement. Seller also has the sole and exclusive
                           right and discretion to control and direct any
                           Reformulation Intellectual Property Litigation,
                           including any challenge to the validity,
                           enforceability or infringement of Reformulation
                           Intellectual Property; provided, however, that Seller
                           shall keep Buyer informed of, and consult with Buyer
                           regarding, Reformulation Intellectual Property
                           Litigation to the extent related to the Injectable
                           Multivitamin Pharmaceutical Field. For Reformulation
                           Intellectual Property Litigation exclusively directed
                           to activity in the Injectable Multivitamin
                           Pharmaceutical Field, Buyer shall assume all costs
                           and retain all proceeds (whether from any damage or
                           reasonable royalty award or the like) ("Proceeds").
                           For Reformulation Intellectual Property Litigation
                           exclusively directed to activity outside of the
                           Injectable Multivitamin Pharmaceutical Field, Seller
                           shall assume all costs and be able to retain all
                           Proceeds. For Reformulation Intellectual Property
                           Litigation directed to activity both in and outside
                           the Injectable Multivitamin Pharmaceutical Field, all
                           costs and all Proceeds shall be allocated between
                           Seller and Buyer on an equitable pro-rata basis.
                           Buyer shall reasonably cooperate in any Reformulation
                           Intellectual Property Litigation, including the
                           obligation to join any such actions as a party, and
                           Seller shall reimburse Buyer for all reasonable
                           out-of-pocket expenses for such cooperation.

                  (vii)    Notwithstanding the foregoing, if Seller (1)
                           identifies activity in the Injectable Multivitamin
                           Pharmaceutical Field which infringes Reformulation
                           Intellectual Property, and (2) determines not to
                           enforce the Reformulation Intellectual Property
                           against such activity, Seller shall so notify Buyer
                           within 60 days of such identification, Buyer shall
                           then have the right and discretion to determine
                           whether to bring an infringement action at its sole
                           cost

                           and expense and be able to retain all Proceeds. Buyer
                           shall give Seller no less than 20 days notice prior
                           to settling any Reformulation Intellectual Property
                           Litigation commenced pursuant to this subparagraph
                           (vii) and the opportunity to reasonably object to the
                           terms of such settlement. Seller shall have no
                           obligation whatsoever to fund or participate in any
                           such Reformulation Intellectual Property Litigation.
                           Seller shall reasonably cooperate in any
                           Reformulation Intellectual Property Litigation
                           commenced by Buyer pursuant to this subparagraph
                           (vii) and Buyer shall reimburse Seller for all
                           reasonable out-of-pocket expenses for such
                           cooperation. Buyer shall have no right under any
                           circumstances to commence Reformulation Intellectual
                           Property Litigation for conduct outside of the

         Buyer's personnel with full access to the files and documents to the
         extent pertaining to such reformulation activities.

         (d)      Any and all costs and expenses associated with Seller's
         Reformulation Efforts shall be borne by the Seller.

         required by, applicable Governmental or Regulatory Authorities that are

<PAGE>

         11.02(a) or Section 11.02(b), but in no event shall the indemnifying
         Party be liable for any Damages that result from failure to provide

         officers, employees and agents (collectively, the "Indemnitees" and

         any third party that are subject to indemnification as provided for in
         Section 11.02(a) or Section 11.02(b) (a "Third Party Claim") shall be
         governed by and be contingent upon the following additional terms and
         conditions:

                  (i)      At its option, the indemnifying Party may assume the
                           defense of any Third Party Claim by giving written
                           notice to the Indemnified Party at any time after the
                           indemnifying Party's receipt of an Indemnification
                           Claim Notice with respect to such Third Party Claim.
                           The assumption of the defense of a Third Party Claim
                           by the indemnifying Party shall be construed as an
                           acknowledgment that the indemnifying Party is liable
                           to indemnify any Indemnitee for Damages in respect of
                           such Third Party Claim. Upon assuming the defense of
                           a Third Party Claim, the indemnifying Party may
                           appoint as lead counsel in the defense of the Third
                           Party Claim any legal counsel selected by the
                           indemnifying Party. In the event the indemnifying
                           Party assumes the defense of a Third Party Claim, the
                           Indemnified Party shall immediately deliver to the
                           indemnifying Party all original notices and documents
                           (including court papers) received by any Indemnitee
                           in connection with the Third Party Claim. Should the
                           indemnifying Party assume the defense of a Third
                           Party Claim, the indemnifying Party shall not be
                           liable to the Indemnified Party or any other
                           Indemnitee for any legal expenses subsequently
                           incurred by such Indemnified Party or other
                           Indemnitee in connection with the analysis, defense
                           or settlement of the Third Party Claim. In the event
                           that it is later determined that the negligence or
                           willful misconduct of the Indemnified Party caused,
                           or was a contributing cause to, the Third Party Claim
                           or the Damages relating thereto, the Indemnified
                           Party shall reimburse the indemnifying Party for the
                           legal costs and all costs and expenses (including
                           attorneys' fees and costs of suit) and any Damages,
                           or its equitable proportion, as the case may be,
                           incurred by the indemnifying Party in its defense of
                           the Third Party Claim with respect to such
                           Indemnitee.

                  (ii)     Without limiting Section 11.02(d)(i), any Indemnitee
                           shall be entitled to participate in, but not control,
                           the defense of such Third Party Claim and to employ
                           counsel of its choice for such purpose; provided,
                           however, that such employment shall be at the
                           Indemnitee's own expense unless (A) the employment
                           thereof has been specifically authorized by the
                           indemnifying Party in writing, or (B) the
                           indemnifying Party has failed to assume the defense
                           and employ counsel in accordance with Section
                           11.02(d)(i) (in which case the Indemnified Party
                           shall control the defense).

                  (iii)    With respect to any Damages relating solely to the
                           payment of money damages in connection with a Third
                           Party Claim and that will not result in the
                           Indemnitee's becoming subject to injunctive or other
                           relief or otherwise adversely affect the business of
                           the Indemnitee in any manner, and as to which the
                           indemnifying Party shall have acknowledged in writing
                           the obligation to indemnify the Indemnitee hereunder,
                           the indemnifying Party shall have the sole right to
                           consent to the entry of any judgment, enter into any
                           settlement or otherwise dispose of such Damages, on
                           such terms as the indemnifying Party, in its sole
                           discretion, shall deem appropriate. With respect to
                           all other Damages in connection with Third Party
                           Claims, where the indemnifying Party has assumed the
                           defense of the Third Party Claim in accordance with
                           Section 11.02(d)(i), the indemnifying Party shall
                           have authority to consent to the entry of any
                           judgment, enter into any settlement or otherwise
                           voluntarily dispose of such Damages; provided that it
                           obtains the prior written consent of the Indemnified
                           Party (which consent shall not be unreasonably
                           withheld or delayed). The indemnifying Party shall
                           not be liable for any settlement or other voluntary
                           disposition of Damages by an Indemnitee that is
                           reached without the written consent of the
                           indemnifying Party. Regardless of whether the
                           indemnifying Party chooses to defend or prosecute any
                           Third Party Claim, no Indemnitee shall admit any
                           liability with respect to, or settle, compromise or
                           discharge, any Third Party Claim without the prior
                           written consent of the indemnifying Party.

                  (iv)     Regardless of whether the indemnifying Party chooses
                           to defend or prosecute any Third Party Claim, the
                           Indemnified Party shall, and shall cause each other
                           Indemnitee to, cooperate in the defense or
                           prosecution thereof and shall furnish such records,
                           information and testimony, provide such witnesses and
                           attend such conferences, discovery proceedings,
                           hearings, trials and appeals as may be reasonably
                           requested in connection therewith. Such cooperation
                           shall include access during normal business hours
                           afforded to the


                                      F-36

                           indemnifying Party to, and reasonable retention by
                           the Indemnified Party of, records and information
                           that are reasonably relevant to such Third Party
                           Claim, and making Indemnitees and other employees and
                           agents available on a mutually convenient basis to
                           provide additional information and explanation of any
                           material provided hereunder, and the indemnifying
                           Party shall reimburse the Indemnified Party for all
                           its reasonable out-of-pocket expenses in connection
                           therewith. To the extent the records of the
                           Indemnitee referenced in this Section 11.02(d)(iv)
                           are privileged by an attorney-client relationship,
                           the parties shall cooperate in a manner as to
                           preserve such privilege but to afford the
                           indemnifying Party with all information relevant to
                           such Third Party Claim.

         Taxes owed as a result of receipt of such indemnification, and (ii) the
         net amount of any insurance proceeds paid to the Indemnified Party

         litigation and other matters necessary in respect of the Seller's
         ownership, prior to the Closing Date, of the Purchased Assets, Products

         been able to do so, and (ii) Seller has been advised by counsel that
         disclosure is required to be made

         exchange or another similar regulatory body. In the event that Seller
         is requested or required by documents subpoena, civil investigative
         demand, interrogatories, requests for information, or other similar
         process to disclose any information supplied to Seller in the course of
         its ownership of the Purchased Assets, Seller shall provide Buyer with
         prompt notice of such request or demands or other similar process so

         basis from a source other than the Buyer, provided that such source is
         not bound by a confidentiality agreement with Buyer.

discussions and agreements among the parties with respect to the subject matter
hereof and contains the sole and entire agreement among the parties hereto with
respect to the subject matter hereof.

         SECTION 13.04     WAIVER.

         Any term or condition of this Agreement may be waived at any time by
the party that is entitled to the benefit thereof, but no such waiver shall be
effective unless set forth in a written instrument duly executed by or on behalf
of the party waiving such term or condition. No waiver by any party hereto of
any term or condition of this Agreement, in any one or more instances, shall be
deemed to be or construed as a waiver of the same or any other term or condition
of this Agreement on any future occasion. All remedies, either under this
Agreement or by law or otherwise afforded, will be cumulative and not
alternative.

         SECTION 13.05     AMENDMENT.

         This Agreement may be amended, supplemented or modified only by a
written instrument duly executed by each party hereto.

         SECTION 13.06     THIRD PARTY BENEFICIARIES.

         The terms and provisions of this Agreement are intended solely for the
benefit of each party hereto and their respective successors or permitted
assigns and it is not the intention of the parties to confer third-party
beneficiary rights upon any other Person.

         SECTION 13.07     ASSIGNMENT; BINDING EFFECT.

         Neither this Agreement nor any right, interest or obligation hereunder
may be assigned by any party hereto without the prior written consent of the
other party hereto, other than to an Affiliate or successor entity of such party
with a guarantee of performance by the assigning party, and any attempt to do
so, other than as permitted above, will be void. This Agreement is binding upon,
inures to the benefit of and is enforceable by the parties hereto and their
respective successors and permitted assigns.

         SECTION 13.08     HEADINGS.

         The headings used in this Agreement have been inserted for convenience
of reference only and do not define or limit the provisions hereof.

         SECTION 13.09     SEVERABILITY.

         If any provision of this Agreement is held to be illegal, invalid or
unenforceable under any present or future law, and if the rights or obligations
of any party hereto under this Agreement will not be materially and adversely
affected thereby, (a) such provision will be fully severable, (b) this Agreement
will be construed and enforced as if such illegal, invalid or unenforceable
provision had never compromised a part hereof, (c) the remaining provisions of
this Agreement will remain in full force and effect and will not be affected by
the illegal, invalid or unenforceable provision or by its severance herefrom,
and (d) in lieu of such illegal, invalid or unenforceable provision, there will
be added automatically as a part of this Agreement a legal, valid and
enforceable provision as similar to terms to such illegal, invalid or
unenforceable provision as may be possible and reasonably acceptable to the
parties herein.

         SECTION 13.10     GOVERNING LAW.

         THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF DELAWARE APPLICABLE TO CONTRACTS EXECUTED AND PERFORMED

         SECTION 13.11     CONSENT TO JURISDICTION AND FORUM SELECTION.

         THE PARTIES HERETO AGREE THAT ALL ACTIONS OR PROCEEDINGS ARISING IN
CONNECTION WITH THIS AGREEMENT SHALL BE INITIATED AND TRIED EXCLUSIVELY IN THE
LOCAL AND FEDERAL COURTS LOCATED IN THE STATE OF DELAWARE. THE AFOREMENTIONED
CHOICE OF VENUE IS INTENDED BY THE PARTIES TO BE MANDATORY AND NOT PERMISSIVE IN
NATURE, THEREBY PRECLUDING THE POSSIBILITY OF LITIGATION BETWEEN THE PARTIES
WITH RESPECT TO OR ARISING OUT OF THIS AGREEMENT IN ANY JURISDICTION OTHER THAN
THAT SPECIFIED IN THIS SECTION. EACH PARTY HEREBY WAIVES ANY RIGHT IT MAY HAVE
TO ASSERT THE DOCTRINE OF FORUM NON CONVENIENS OR SIMILAR DOCTRINE OR TO OBJECT
TO VENUE WITH RESPECT TO ANY PROCEEDING BROUGHT IN ACCORDANCE WITH THIS SECTION,
AND STIPULATES THAT THE LOCAL AND FEDERAL COURTS LOCATED IN THE STATE OF
DELAWARE SHALL HAVE PERSONAL JURISDICTION AND VENUE OVER EACH OF THEM FOR
PURPOSES OF LITIGATING ANY DISPUTE, CONTROVERSY OR PROCEEDING ARISING OUT OF OR
RELATED TO THIS AGREEMENT. EACH PARTY HEREBY AUTHORIZES AND AGREES TO ACCEPT
SERVICE OF PROCESS SUFFICIENT FOR PERSONAL JURISDICTION IN ANY ACTION AGAINST IT
AS CONTEMPLATED BY THIS SECTION BY REGISTERED OR CERTIFIED MAIL, RETURN RECEIPT
REQUESTED, POSTAGE PREPAID TO ITS ADDRESS FOR THE GIVING OF NOTICES AS SET FORTH
IN THIS AGREEMENT, OR IN THE MANNER SET FORTH IN SECTION 13.02 OF THIS AGREEMENT
FOR THE GIVING OF NOTICE. ANY FINAL JUDGMENT RECEIVED AGAINST A PARTY IN ANY
ACTION OR PROCEEDING SHALL BE CONCLUSIVE AS TO THE SUBJECT OF SUCH FINAL
JUDGMENT AND MAY BE ENFORCED IN OTHER JURISDICTIONS IN ANY MANNER PROVIDED BY
LAW.

         SECTION 13.12     EXPENSES.

         Except as otherwise provided in this Agreement, each party hereto shall
pay its own expenses and costs incidental to the preparation of this Agreement
and to the consummation of the transactions contemplated hereby.

         SECTION 13.13     COUNTERPARTS.

         This Agreement may be executed in any number of counterparts and by
facsimile, each of which will be deemed an original, but all of which together
will constitute one and the same instrument.

         SECTION 13.14     SCHEDULES, EXHIBITS AND OTHER AGREEMENTS.

         The Exhibits, Schedules, other agreements, certificates and notices
specifically referred to herein, and delivered pursuant hereto, are an integral
part of this Agreement. Any

disclosure that is made in any of the Schedules or certificates delivered
pursuant to this Agreement shall be deemed responsive to any other applicable
disclosure obligation hereunder.

         SECTION 13.15     SELLER AND ITS AFFILIATES.

Agreement shall be to Seller and those of its Affiliates that own or possess the
