Item 5. Other Events

     On June 1, 1998, Neose Technologies, Inc. (the "Company") entered into a
Research and Development Agreement with the Pharmaceutical Research Institute of
Bristol-Meyers Squibb Company, a Delaware corporation ("BMS"), to develop
proprietary processes for the manufacture of complex carbohydrates for two
cancer vaccines being developed by BMS (the "R&D Agreement"). The R&D Agreement
provides for the Company to receive payments upon the completion of certain
milestones. BMS may terminate the R&D Agreement upon ninety days prior
written notice. If BMS decides to purchase any complex carbohydrates from the
Company after commercializing either of its vaccines, the Company and BMS will
need to negotiate the terms of a manufacturing supply agreement.

     On October 12, 1999, the Company entered into an Operating Agreement with
McNeil PPC, Inc., acting through its division McNeil Specialty Products Company
("McNeil"), for the purpose of forming Magnolia Nutritionals LLC, a limited
liability company organized under the laws of the State of Delaware, to develop
the cost-effective production of certain complex carbohydrates (the "Operating
Agreement"). The joint venture replaces and expands the previous research and
development agreement between the Company and McNeil.

     On November 3, 1999, the Company entered into a Collaboration and License
Agreement (the "Collaboration Agreement") with American Home Products
Corporation, acting through its subsidiary company, Wyeth-Ayerst International
Inc. ("Wyeth"), to develop and commercialize a bioactive milk-based carbohydrate
for use in infant and pediatric nutritional formulas marketed by Wyeth. Under
the Collaboration Agreement, the two companies will conduct a joint research and
development program, with Wyeth's activities focused on use of the ingredient in
its pediatric products, and with the Company's activities focused on the
development of commercial scale manufacturing capabilities for the novel
bioactive carbohydrate ingredient. The Collaboration Agreement provides for
development fees payable to the Company prior to commercialization, and
anticipates that the Company will manufacture and sell novel ingredients to
Wyeth, and will receive royalties upon commercialization.

     third party not under an obligation of confidentiality, direct or indirect,
     to the disclosing party not to disclose such information to others, as can
     be demonstrated by competent proof; or

          (v) Is independently developed by the receiving party without regard
     to the information disclosed to it by the other party hereunder, as can be
     demonstrated by competent proof.

     Confidentiality Information may be disclosed as required by applicable law,
provided that the party required to disclose same gives notice to the party from
whom it received the information, and seeks confidential treatment of such
disclosure to the maximum extent permitted by applicable law. Nothing in this
Article 8 is intended or shall be construed as creating or implying any right or
license under any patent rights or other intellectual property rights owned or
controlled by either party by virtue of such party's disclosure of Confidential
Information.

          8.2 The parties further agree that all technical information and data
     produced in the course of completing the PROJECT shall be deemed
     Confidential Information and shall not be

     10.1 BMS agrees to indemnify and hold NTI harmless from any loss, damage or
claim (including, without limitation, attorneys fees) arising from BMS' use of
the GM2 and GD2 materials supplied by NTI hereunder for any purpose, including
clinical studies involving human subjects, except to the extent such claims
primarily arise from the negligence or willful misconduct of NTI in the
preparation of such materials.

     Article 11 - Miscellaneous

     11.1 This Agreement, together with all Exhibits annexed hereto, constitutes
the entire understanding between BMS and NTI with respect to the PROJECT hereof,

instrument executed by all parties. No provision of this Agreement may be waived
by any act, omission or knowledge of a party or its agents or employees, but
only by a writing expressly waiving such provision and signed by the waiving
party. The failure of a party at any time or times to require performance of any
provision hereof shall in no manner affect its rights at a later time to enforce
the same. No waiver by a party of any condition, remedy or term or any other
condition, remedy or term of any successive occasion.

     11.4 No obligations or rights under this Agreement may be assigned or
delegated by NTI without the prior written consent of BMS.

     5. Milligram quantities [*] of non-GMP GD2 material will be
        available within thirty-six (36) weeks of project start date.

     6. NTI will deliver [*] batch of cGMP GD2 material within
        fourteen (14) weeks of delivering a [*] sample of GD2 to BMS.

     cGMP GD2 to BMS on a biweekly basis. At NTI's discretion, NTI may
     complete an intermediate scale GD2 batch prior to the first [*]
     delivery, provided that there is no impact on the Project Schedule as
     described in this Appendix. At BMS' discretion, BMS may reduce the
     specified batch size (stated herein as [*]) prior to start of
     manufacture, as clinical needs are established.

     The research and development program required to meet the project
assumptions stated above will be funded according to the following payment
structure:


1. Project Start (Project Initiation Fee)                           $[*]
2. Delivery of mg quantities of non-GMP GM2                         $[*]
3. Delivery of full [*] of cGMP GM2                                 $[*]
4. Delivery of mg quantities of non-GMP GD2                         $[*]
5. Delivery of full [*] of cGMP GD2                                 $[*]

     The total cost for this Research and Development Agreement will be $[*] and
include all costs associated with the preparation of documentation required for
cGMP practices as well as the actual manufacturing costs of non-GMP and GMP
deliveries of both gangliosides.

     In the event that BMS requests the [*] deliveries of either ganglioside be
manufactured without strict cGMP controls (as may be occasioned by the granting
of "Starting Material" status by the FDA), the royalty payment will be modified
as follows:


Item No. 3 - Delivery of full [*] of cGMPGM2:                       $[*]
Item No. 5 - Delivery of full [*] of cGMP GD2                       $[*]

     NTI will commit to supplying all quantities of ganglioside required by BMS
for product development purpose (process development and validation, product
stability, clinical trials, etc.) For requirements in excess of the [*] batches
of each GM2 and GD2, the price per gram shall be $[*] for cGMP material and $[*]
for non-GMP material.

     Development Terms

     1. NTI will reserve all quantities of gangliosides prepared
        during the process development trials (regardless of quality)
        for transfer to BMS, except that NTI may retain such
        quantities of GM2 and GD2 as are necessary for the maintenance
        of standards, analytical methods and quality control. Excess
        quantities of ganglioside transferred to BMS hereunder will be
        used to assist BMS in refining analytical methods and
        developing specifications for the gangliosides.

     2. BMS and NTI will develop complete documentation of the
        manufacturing process for the preparation of GM2 and GD2. In
        the event that NTI is incapable of meeting or unwilling to
        meet BMS' production requirements for either GM2 or GD2, BMS
        and NTI will work together to transfer NTI technology to a
        mutually agreed upon third party or to BMS' internal
        manufacturing network.

     3. In the event NTI is unable to offer acceptable quality
        ganglioside material derived from plant ceramide in the time
        agreed to in the Research and Development Agreement, NTI will,
        upon request from BMS, revert to the production of
        gangliosides from [*]. Monies paid to support the [*] route
        will be transferred directly the [*] process development
        effort.

          2.8.1 Notice Generally. A notice of meeting shall specify the place,
     day and hour of the meeting and any other information required by any
     provision of the Act, the Certificate or this Agreement. When a meeting is
     adjourned, it shall not be necessary to give any notice of the adjourned
     meeting or of the business to be transacted at an adjourned meeting, other
     than by announcement at the meeting at which the adjournment is taken,
     unless the adjournment is for more than sixty (60) days or the Members or
     the Management Committee fix a new record date for the adjourned meeting in
     which event notice shall be given in accordance with Section 2.8.2 or
     Section 2.8.3, as applicable.

          2.8.2 Notice of Meetings of Management Committee. Either Member can

     (48) hours (in the case of notice by telegraph, courier service or express
     mail) or five (5) days (in the case of notice by first class mail) before
     the time at which the meeting is to be held. Every such notice shall state
     the time and place of the meeting. Neither the business to be transacted
     at, nor the purpose of, any meeting of the Management Committee need be

     waiver thereof in writing, signed by the person or persons entitled to the

     equivalent to the giving of the notice. Neither the business to be
     transacted at, nor the purpose of, a meeting need be specified in the
     waiver of notice of the meeting. Attendance of a person at any meeting
     shall constitute a waiver of notice of the meeting except where a person
     attends a meeting for the express purpose of objecting, at the beginning of

     lawfully called or convened.

          2.8.5 Use of Conference Telephone and Similar Equipment. Any Manager

     other. Participation in a meeting pursuant to this Section shall constitute

          2.8.6 Consent in Lieu of Meeting. Any action required or permitted to

     taken without a meeting if, prior or subsequent to the action, written
     consents describing the action to be taken are signed by each Manager or
     Member, respectively, entitled to vote thereon. Any action required or
     permitted to be taken at a meeting of the Management Committee or Members
     may be taken without a meeting if, prior or subsequent to the action,
     written consents describing the action to be taken are signed by the
     minimum number of Managers or Members that would be necessary to authorize
     the action at a meeting at which all Managers or Members entitled to vote
     thereon were present and voting. The consents shall be filed with the
     Management Committee. Prompt notice of the taking of the Company action
     without a meeting by less than unanimous written consent shall be given to
     those Members who have not consented in writing.

     notice of, or to vote at, any meeting of Members or any adjournment of the
     meeting, or Members entitled to receive payment of any distribution, or to
     make a determination of Members for any other purpose, the date on which
     notice of the meeting is mailed or the date on which the resolution
     declaring the distribution or relating to such other purpose is adopted, as
     the case may be, shall be the record date for the determination of Members.
     Only Members of record on the date fixed shall be so entitled
     notwithstanding any permitted transfer of a Member's Interest in the
     Company after any record date fixed as provided in this Section. When a
     determination of Members entitled to vote at any meeting of Members has
     been made as provided in this Section, the determination shall apply to any
     adjournment of the meeting.

          2.9.3 Quorum. A meeting of Members of the Company duly called shall
     not be organized for the transaction of business unless a quorum is
     present. The presence of a Majority-In-Interest represented in person or by
     proxy shall constitute a quorum at any meeting of Members. In the absence
     of a quorum at any meeting, Members who own a majority of the Percentage
     Interests so represented may adjourn the meeting from time to time for a
     period not to exceed 60 days without further notice. However, if the
     adjournment is for more than 60 days, or if after the adjournment a new
     record date is fixed for the adjourned meeting, a notice of the adjourned
     meeting shall be given to each Member of record entitled to vote at the
     meeting. At an adjourned meeting at which a quorum shall be present or
     represented, any business may be transacted which might have been
     transacted at the meeting as originally noticed. The Members present at a
     duly organized meeting may continue to transact business until adjournment,
     notwithstanding the withdrawal during the meeting of Members whose absence
     would cause less than a quorum.

circumstances, including the reliance in good faith upon the records of the
Company and upon such information, opinions, reports or statements presented to
the Company by the Management Committee, Members, officers, employees or
committees of the Company or by any other person, as to matters the Management
Committee reasonably believes are within such other person's professional or
expert competence and who has been selected with reasonable care by or on behalf
of the Company. The Management Committee does not, in any way, guarantee the
return of the Members' Capital Contributions or a profit for the Members from

otherwise specified in the notice, the acceptance of the resignation shall not

who is also a Member shall not affect the Manager's rights as a Member and shall
not constitute a withdrawal of a Member.

time, without assigning any cause, by the Member who designated such Manager.
The removal of a Manager who is also a Member shall not affect the Manager's

     (or its Affiliates) will have the right to purchase [*] from the Company
     for incorporation into [*], at a price equal to the Actual Cost plus [*]
     per pound for such [*]. Other than as part of an [*], MSPC shall not sell
     any [*] purchased from the Company without Neose's prior written consent.
     The Company shall not sell or cause to be sold any [*] for use in the
     manufacture of a product that directly competes with any [*]. MSPC will
     have the right to purchase [*] for use in the manufacture of MSPC products
     other than [*] on terms at least as favorable as the most favorable terms
     given to any third party.

          5.1.2 Production Forecasts. During the term of this Agreement, MSPC
     shall provide to the Company no later than 60 days prior to the first day
     of each calendar quarter a forecast of MSPC's orders for [*] for the next
     12 calendar months. The first calendar quarter of each such forecast shall
     be referred to as the "First Quarter Forecast". The second quarter of each
     such forecast may be adjusted by MSPC for each [*] in the next subsequent
     calendar quarter's forecast (at which point in time the second quarter
     forecast becomes the First Quarter Forecast), provided that no such
     adjustment shall (absent the consent of Neose) cause such First Quarter
     Forecast to be greater than 115% or less than 85% of the second quarter
     forecast for such [*] contained in the immediately preceding forecast
     submitted under this Section.

          5.1.3 Purchase Orders. All purchase orders for [*] must be submitted
     in accordance with the Company's procedures for the receipt and filling of
     purchase orders. Prior to the date of notice to MSPC of the Company's

     employ the analogous procedures of MSPC for such processes. As long as it
     has adequate production capacity, the Company shall be obligated to supply
     [*] pursuant to such purchase orders to the extent the purchase orders do
     not exceed by an amount greater than 15% the latest First Quarter Forecast.
     MSPC shall at all times be obliged to purchase the quantity of [*] equal to
     at least 85% of each First Quarter Forecast during the calendar quarter to
     which such First Quarter Forecast relates.

          5.1.4 Invoice and Payment for [*]. The Company shall invoice MSPC for
     [*] sold to MSPC upon shipment as follows:

                5.1.4.1 With respect to [*] to be included in [*], the invoiced
          amount per pound of [*] shall be equal to the estimated Actual Cost
          thereof as established from time to time by the Management Committee
          pursuant to Section 5.1.5 plus [*]. MSPC will pay such invoiced amount
          within 30 days after receipt. Within 60 days after the end of each
          Fiscal Year, the Management Committee shall determine the Actual Cost
          of the [*] sold to MSPC from the accounting records of the Company for

          indicating the results of such determination. If MSPC does not dispute
          such determination, the Company or MSPC, as the case may be, shall
          make an adjusting payment to the other within 10 days after receipt of
          such notice as may be required to assure that MSPC has paid only the
          agreed price for such [*] purchased during such Fiscal Year. If MSPC
          disputes the determination of such Actual Cost, and the Designated
          Representatives cannot resolve such dispute within 10 days after the
          Company has received notice that MSPC disputes such determination, an
          independent certified public accountant will be asked by the
          Management Committee to make a final determination within 60 days.

               5.1.4.2 With respect to all other [*] purchased by MSPC, the
          Company will invoice MSPC and MSPC will pay such invoice in accordance
          with the terms in effect for sales to third parties.

     First Quarter Forecast, the Management Committee will provide to MSPC an
     estimate of the Actual Cost of the [*] to be sold pursuant to such
     Forecast.

     5.2 Loans. Until the Company generates sufficient Income in excess of
Losses, MSPC will from time to time make non-interest bearing, non-recourse
loans to the Company as necessary to fund (i) operating losses and (ii) the
Construction Budget in excess of $[*], such loans to be payable out of the
Company's Net Cash Flow ratably over a seven-year period commencing on the
earlier of (i) September 30, 2006 or (ii) the date on which Neose attains a
Percentage Interest of 50% after having had a lesser Percentage Interest.

     5.3 Rejected Proposals.

         5.3.1 New Products. In the event one party, either as a Member,
     through the Managers appointed by it or through the members of the Joint
     Development Committee appointed by it, as applicable, rejects a proposal to
     pursue a new product, the "Rejecting Member" may elect to (i) allow the
     "Developing Member" to pursue the new product outside the Company, in which
     case the Joint Information will be sublicensed to the Developing Member for
     the sole purpose of the development, manufacture and commercialization of
     such new product or (ii) allow the Developing Member to invest in the
     Company as a capital contribution, with an appropriate adjustment in
     Percentage Interests, all amounts relating to the development of such new
     product. Such election will be made within sixty (60) days after such
     rejection by notice given to the Developing Member. The Developing Member
     will have one hundred and eighty (180) days in which to pursue the option

     proposal to expand production capacity by constructing additional
     manufacturing capacity, the "Rejecting Member" may elect to (i) allow the

     purpose of constructing and operating such manufacturing capacity and
     selling the products thereof or (ii) allow the Manufacturing Member to
     invest in the Company as a Capital Contribution, with an appropriate
     adjustment in Percentage Interests, the amount of capital expenditures
     required to construct such manufacturing capacity. Such election will be
     made within sixty (60) days after such rejection by notice given to the
     Manufacturing Member. The Manufacturing Member will have one hundred and
     eighty (180) days in which to pursue the option offered by such election
     without having to resubmit the proposal to the Rejecting Member.

          5.3.3 Sale or License of Products and Technology. A "Proposing Member"
     may propose the sale or license to a third party of any of the Company's
     technology or products not then in commercial production, subject to
     Section 5.1.1. If the "Objecting Member" objects to such sale or license,
     it shall give written notice to the Proposing Member of its objection
     ("Objection Notice") within thirty (30) days after such proposal. If
     Objection Notice is given, the Objecting Member shall have the right within
     thirty (30) days after such Objection Notice to give notice to the
     Proposing Member of the terms and conditions on which the Objecting Member
     would purchase such product or license such technology ("Objector's
     Terms"). If (i) the Objecting Member does not give its Objection Notice
     within the specified time period, (ii) the Objecting Member does not give
     notice of its Objector's Terms within the specified time period, or (iii)
     the Members cannot agree on the Objector's Terms within thirty (30) days
     after the Objector's Terms have been given, the Proposing Member may
     require the Company to sell such product or license such technology to a
     third party on terms and conditions more favorable to the Company than
     those contained in the Objector's Terms.

     5.4 Personnel and Research Services. From time to time as agreed by the
Members, either Member may provide personnel and research services to the
Company. The Members shall negotiate in good faith the fees for such services to
be paid by the Company to the Member providing such services.

6.   CONTRIBUTIONS AND CAPITAL ACCOUNTS.

     6.1 Capital Contributions. Each Member shall make capital contributions (a
"Capital Contribution") to the Company in accordance with Exhibit 6.1. In
addition, upon execution of this Agreement, each Member shall make non-cash
Capital Contributions to the Company as specified in Section 7.1. The Members
shall receive Percentage Interests in the Company which reflect the percentage
of all Capital Contributions hereunder contributed by such Member.

     6.2 Neose's Option to Increase Percentage Interest. Neose will have the
option, exercisable from time to time until September 30, 2006, to increase its
Percentage Interest to up to 50% by making payments ("Payments") to MSPC in
exchange for MSPC transferring a portion of its Percentage Interest to Neose
until the combined total of Payments and Capital Contributions by Neose equals
50% of the combined Capital Contributions of both Neose and MSPC. With respect
to each payment made by Neose under this Section, the Percentage Interests of
each Member in the Company will be recalculated in accordance with the last
sentence of Section 6.1.

Account for each Member.

     6.4 Withdrawal of Capital. A Member shall not be entitled to withdraw any
part of such Member's Capital Account or to receive any distribution from the
Company, except as provided in this Agreement.

     6.5 Additional Capital Contributions. No Member shall be required to make
any additional capital contribution to the Company or to restore any deficit in
such Member's Capital Account, except as provided in this Agreement, and such

other person for any purpose.

     6.6 Interest on Capital Contribution. No interest shall be due from the
Company on any Capital Contribution of any Member.

     6.7 Priority and Return of Capital. Except as may be expressly provided in
this Agreement, no Member shall have priority over any other Member either for

Section shall not apply to loans (as distinguished from Capital Contributions)
which a Member has made or may make to the Company pursuant to Section 5.2
or 6.9.

     6.8 Limitation Upon Liability of Members. Except as may be expressly
provided in this Agreement or under the Certificate, the personal liability of
each Member to the Company, to the other Members, or to the creditors of the
Company or any third party for losses, debts or liabilities of the Company shall
be limited to the amount of its Capital Contribution which has not theretofore
been returned to it as a distribution (including a distribution upon
liquidation). For purposes of the foregoing sentence, except for payments to
MSPC pursuant to Section 5.2 and payments to any Member to repay loans made in
accordance with Section 6.9, distributions to a Member shall first be deemed to
be a return of its Capital Contribution. No Member shall at any time be liable
or held accountable to the Company, to other Members, to creditors of the
Company or to any other third party for or on account of any negative balance in
its Capital Account.

     6.9 Loans. If any Member makes any loan or loans to the Company, or
advances money on its behalf, the amount of any such loan or advance shall not
be deemed an increase in, or contribution to, the Capital Account of the lending
Member or entitle the lending Member to any increase in his, her or its share of
the distributions of the Company. Except as provided in Section 5.2, interest
shall accrue on any such loan at an annual rate agreed to by the Company and the
lending Member.

documentation so that Members may be informed of the continuing prosecution, and

action to be taken in connection therewith. This notice concerning filing must
be in writing and must identify the countries and pertinent deadlines. The
absence of such a notice from the Company to Members will be considered an

Patents and Patent Applications with respect to a Joint Invention at its own
expense in any country in which the Company has elected not to file, prosecute
or maintain a Patent or Patent Application therefor in accordance with this
Section and Patent Applications and resulting Patents will be owned by the

     7.11 Patent Infringement

          7.11.1 If any Member or the Company receives notice pertaining to
     infringement or potential infringement of any issued Patent included within
     Joint Patent Rights, Neose Patent Rights, or MSPC Patent Rights, the person
     receiving such notice shall notify the other Members and the Company, as
     appropriate, within ten (10) days after receipt.

          7.11.2 If any Member or the Company learns of the substantial
     infringement of any Patent included within Joint Patent Rights, Neose
     Patent Rights, or MSPC Patent Rights, the person receiving such notice
     shall notify the others in writing and provide reasonable evidence of
     infringement. Neither the Company nor any Member will notify a third party
     of the infringement of any Patent Rights without first obtaining consent of
     the all Members, which consent will not be unreasonably denied.

          7.11.3 A Member may request that the Company take legal action against
     the infringement of Joint Patent Rights. If the Company has not commenced
     suit within ninety (90) days following the date of such request, the
     requesting Member will have the right to bring suit for patent infringement
     of Joint Patent Rights, at its own expense, if and only if the Company
     elects not to commence suit and if the infringement occurred during the
     period and in a jurisdiction where the Company had exclusive rights under
     this Agreement. If, however, Member elects to bring suit in accordance with
     this Section, the Company may thereafter join that suit at its own expense.

          7.11.5 Legal action will be at the expense of the party bringing suit
     and all damages recovered thereby will belong to the party bringing suit,
     but legal action brought jointly by Members and fully participated in by
     both will be at the joint expense of the parties and all recoveries will be
     shared jointly by them in proportion to the share of expense paid by each
     party.

          7.11.6 Each Member and the Company shall cooperate with each other in
     litigation proceedings instituted hereunder but at the expense of the party
     bringing suit. Litigation will be controlled by the party bringing the
     suit, except that the Company may be represented by counsel of its choice
     in any suit brought by a Member.

     7.12 Product Marking. The Company and the parties shall mark all products
made, used or sold under the terms of this Agreement, or their containers, in
accordance with the applicable patent marking laws.

     8.2 Losses. After giving effect to the special allocations set forth in
Section 8.3, Losses for any Fiscal Year shall be allocated as follows:

         8.2.1 First, to MSPC to the extent such Losses are attributable to any
     loans provided to the Company pursuant to Section 5.2; and

         8.2.2 Second, to the members in accordance with their respective
     Percentage Interests.

     8.3 Special Allocations. The following special allocations shall be made in
the following order and priority:

         8.3.1 In accordance with Code Section 704(c) and the Treasury
     Regulations thereunder, income, gain, loss and deduction with respect to
     any property contributed to the capital of the Company shall, solely for
     tax purposes, be allocated among the Members so as to take account of any
     variation between the adjusted basis of such property to the Company for
     federal income tax purposes and its Gross Asset Value.

         8.3.2 In the event the Gross Asset Value of any Company asset is
     adjusted pursuant to this Agreement, subsequent allocations of income,
     gain, loss and deduction with respect to such asset shall take account of
     any variation between the adjusted basis of such asset for federal income
     tax purposes and its Gross Asset Value in the same manner as under Code
     Section 704(c) and the Treasury Regulations thereunder.

         8.3.3 Any elections or other decisions relating to Sections 8.3.1 or
     8.3.2 shall be made by the Management Committee in a manner that reasonably
     reflects the purpose and intention of this Agreement. Allocations pursuant
     to Sections 8.3.1 or 8.3.2 are solely for purposes of federal, state and
     local taxes and shall not affect, or in any way be taken into account in
     computing, any Member's Capital Account or share of Income, Losses, other
     items, or distributions pursuant to any provision of this Agreement.

         8.3.4 If there is a net decrease in Company Minimum Gain during any
     Fiscal Year, each Member shall be specially allocated items of Company
     income and gain for such year (and, if necessary, subsequent years) in an
     amount equal to such Member's share of the net decrease in Company Minimum
     Gain (determined in accordance with Treasury Regulation Section
     1.704-2(g)(2)). Allocations pursuant to the preceding sentence shall be
     made in proportion to the respective amounts required to be allocated to
     each Member. The items to be so allocated shall be determined in accordance
     with Treasury Regulation Section 1.704- 2(i). This Section 8.3.4 is
     intended to comply with the minimum gain chargeback requirement in Treasury
     Regulation Section 1.704-2(f) and shall be interpreted consistent with such
     Section.

         8.3.5 Notwithstanding any other provision of this Section 8.3 except
     the foregoing provisions of this Section 8, if there is a net decrease in
     Member Minimum Gain during any Fiscal Year, each Member who has a share of
     the Member Minimum Gain attributable to such Member Nonrecourse Debt
     (determined in accordance with Treasury Regulation


                                       27

<PAGE>


     Section 1.704-2(i)(5)) shall be specially allocated items of Company income
     and gain for such year (and, if necessary, subsequent years) in an amount
     equal to such Member's share of the net decrease in Member Minimum Gain
     (determined in accordance with Treasury Regulation Section 1.704-2(i)(4)).
     Allocations pursuant to the preceding sentence shall be made in proportion
     to the respective amounts required to be allocated to each Member. The
     items to be so allocated shall be determined in accordance with Treasury
     Regulation Section 1.704-2(j)(2)(ii). This Section 8.3.5 is intended to
     comply with the minimum gain chargeback requirement in Treasury Regulation
     Section 1.704-2(i)(4) and shall be interpreted consistent with such
     Section.

         8.3.6 In the event any Member unexpectedly receives any adjustments,
     allocations, or distributions described in Treasury Regulation Section
     1.704-1(b)(2)(ii)(d)(4), (5) or (6) which causes or increases a Member's
     Capital Account Deficit as of the end of the taxable year to which such
     allocation, distribution or adjustment relates, then items of Company
     income and gain shall be specially allocated (prior to any other allocation
     required by Section 8.1, but after the allocations required by the
     foregoing provisions of this Section 8.3) to such Member in an amount and
     manner sufficient to eliminate (to the extent required by the Treasury
     Regulations) the Capital Account Deficit balances if any, created by such
     adjustments, allocations, or distributions as quickly as possible; provided
     that an allocation pursuant to this Section 8.3.6 shall be made only if and
     to the extent that such Member would have a Capital Account Deficit after
     all other allocations provided for in this Section 8 have been tentatively
     made as if this Section 8.3.6 was not in the Agreement. This Section 8.3.6
     is intended to comply with the Qualified Income Offset Rules of the
     Treasury Regulations and shall be interpreted consistent with such rules.

     8.4 Company Nonrecourse Deductions. Any Company Nonrecourse Deductions for
any Fiscal Year or other period shall be allocated among the Members in
accordance with their respective Percentage Interests.

     8.5 Member Nonrecourse Deduction. Any Member Nonrecourse Deductions for any
Fiscal Year or other period shall be allocated to the Member bearing the
economic risk of loss for the debt to which such Deductions are attributable, as
provided in Treasury Regulation Section 1.704-2(i).

     8.6 Allocation to Members. Allocations to be made to Members having
negative balances in their Capital Accounts shall be made to each such Member in
the proportion that the negative balance in his Capital Account bears to the
aggregate negative balances in the Capital Accounts of all such Members.

     8.7 Change in Member's Interest. If during any Fiscal Year of the Company
there is a change in any Member's Percentage Interest, then for purposes of
complying with Section 706(d) of the Code, the determination of items of Income
and Loss allocable to any such period shall be made by using any method
permissible under the Code or Treasury Regulations as may be determined by the
Management Committee.

     distribution, all liabilities of the Company, other than liabilities to
     Members on account of their Interests in the Company and liabilities for
     which the recourse of creditors is limited to specified property of the
     Company, exceed the fair value of the assets of the Company, except that
     the fair value of property that is subject to a liability for which the
     recourse of creditors is limited shall be included in the assets of the
     Company only to the extent that the fair value of that property exceeds
     that liability.

         9.2.2 A Member who receives a distribution in violation of Section
     9.2.1, and who knew at the time of the distribution that the distribution
     violated this Section, shall be liable to the Company for the amount of the

     no liability under this Section, the Act or other applicable law for the
     amount of the distribution after the expiration of three years from the
     date of the distribution unless an action to recover the distribution from
     such Member is commenced prior to the expiration of the said three-year
     period and an adjudication of liability against such Member is made in the
     action.

     9.3 Amounts of Tax Paid or Withheld. All amounts paid or withheld pursuant

          to such Manager that such transfer is exempt from the registration
          requirements of the 1933 Act and applicable state securities laws; and

               10.2.1.4 such assignment or transfer shall be reflected in a
          revised Exhibit 6.1 to this Agreement.

          10.2.2 A person who acquires an Interest in the Company without
     satisfying Section 10.1 and this Section 10.2 shall be entitled to receive
     only the allocations and distributions attributable to the acquired
     Interest in the Company, if any, but shall not be entitled to any other
     rights of a Member.

          10.2.3 A person who is an assignee of an Interest in the Company may
     be admitted to the Company as a Member and may receive an Interest in the
     Company without making a contribution or being obligated to make a
     contribution to the Company.

     10.3 No Resignation of Members. A Member may not withdraw or resign from
the Company prior to dissolution or winding up of the Company. If a Member who
is an individual dies or a court of competent jurisdiction adjudges the
individual to be incompetent to manage the person or property of the individual,
the executor, administrator, guardian, conservator or other legal representative
of the Member may exercise all of the rights of the Member for the purpose of
settling the estate or administering the property of the Member, including the
power under this Agreement of an assignee to become a Member. If a Member is a
corporation, trust or other entity and is dissolved or terminated, the powers of
that Member may be exercised by its legal representative or successor.

11.  INDEMNIFICATION.

     11.1 Indemnification by the Company.

          11.1.1 The Company shall indemnify an Indemnified Representative
     against any Liability incurred in connection with any Proceeding in which
     the Indemnified Representative may be involved as a party or otherwise by
     reason of the fact that such person is or was serving in an Indemnified
     Capacity, including, without limitation, liabilities resulting from any
     actual or alleged breach or neglect of duty, error, misstatement or
     misleading statement, negligence, gross negligence or act giving rise to
     strict or products liability, except (a) where such indemnification is
     expressly prohibited by applicable law; (b) where the conduct of the
     Indemnified Representative has been finally determined (i) to constitute
     willful misconduct or recklessness sufficient in the circumstances to bar
     indemnification against liabilities arising from the conduct, or (ii) to be
     based upon or attributable to the receipt by the Indemnified Representative
     from the Company of a personal benefit to which the Indemnified
     Representative is not legally entitled; or (c) to the extent such
     indemnification has been finally determined in a final adjudication to be
     otherwise unlawful.

          11.1.2 If an Indemnified Representative is entitled to indemnification
     in respect of a portion, but not all, of any Liabilities to which such
     person may be subject, the Company shall indemnify such Indemnified
     Representative to the maximum extent for such portion of the Liabilities to
     which he or she is entitled.

          11.1.3 The termination of a proceeding by settlement shall not create
     a presumption that the Indemnified Representative is not entitled to
     indemnification.

          11.1.4 To the extent that an Indemnified Representative of the Company
     has been successful on the merits or otherwise in defense of any proceeding
     or in defense of any claim, issue or matter therein, such person shall be
     indemnified against expenses (including without limitation attorneys' fees
     and disbursements) actually and reasonably incurred by such person in
     connection therewith.


                                       31

<PAGE>


     11.2 Proceedings Initiated by Indemnified Representatives. Notwithstanding
any other provision of this Section, the Company shall not indemnify under this
Section an Indemnified Representative for any liability incurred in a proceeding
initiated (which shall not be deemed to include counterclaims or affirmative
defenses) or participated in as an intervenor or amicus curiae by the person
seeking indemnification unless such initiation of or participation in the
proceeding is authorized, either before or after its commencement, by the
unanimous vote of the Members or Managers in office. This Section does not apply
to reimbursement of expenses incurred in successfully prosecuting or defending
the rights of an Indemnified Representative granted by or pursuant to this
Section.

     11.3 Advancing Expenses. The Company shall pay the expenses (including
attorneys' fees and disbursements) incurred in good faith by an Indemnified
Representative in advance of the final disposition of a proceeding described in
Section 11.1 or the initiation of or participation in which is authorized
pursuant to Section 11.2 upon receipt of an undertaking by or on behalf of the
Indemnified Representative to repay the amount if it is ultimately determined
that such person is not entitled to be indemnified by the Company pursuant to
this Section. The financial ability of an Indemnified Representative to repay an
advance shall not be a prerequisite to the making of such advance.

     11.4 Securing of Indemnification Obligations. To further effect, satisfy or
secure the indemnification obligations provided in this Section or otherwise,
the Company may maintain insurance, obtain a letter of credit, act as
self-insurer, create a reserve, trust, escrow, cash collateral or other fund or
account, enter into indemnification agreements, pledge or grant a security
interest in any assets or properties of the Company, or use any other mechanism
or arrangement whatsoever in such amounts, at such costs, and upon such other
terms and conditions as the Members or Management Committee shall deem
appropriate. Absent fraud, the determination of the Members or Management
Committee with respect to such amounts, costs, terms and conditions shall be
conclusive against all Members, security holders, officers and Managers and
shall not be subject to voidability.

     11.5 Payment of Indemnification. An Indemnified Representative shall be
entitled to indemnification within 30 days after a written request for
indemnification has been delivered to the secretary of the Company. The
indemnification pursuant to this Section shall be made only from the assets of
the Company, and no Member shall be personally liable therefor.

     11.6 Contribution. If the indemnification provided for in this Section or
otherwise is unavailable for any reason in respect of any liability or portion
thereof, the Company shall contribute to the liabilities to which the
indemnified representative may be subject in such proportion as is appropriate
to reflect the intent of this Section or otherwise.

     11.7 Contract Rights; Amendment or Repeal. All rights under this Section
shall be deemed a contract between the Company and the Indemnified
Representative pursuant to which the Company and each Indemnified Representative
intend to be legally bound. Any repeal, amendment or modification hereof shall
be prospective only and shall not affect any rights or obligations then
existing.


                                       32

<PAGE>


     11.8 Scope of Section. The rights granted by this Section shall not be
deemed exclusive of any other rights to which those seeking indemnification,
contribution or advancement of expenses may be entitled under any statute,
agreement, vote of disinterested Members or disinterested Managers or otherwise,
both as to action in an indemnified capacity and as to action in any other
capacity. The indemnification, contribution and advancement of expenses provided
by or granted pursuant to this Section shall continue as to a person who has
ceased to be an indemnified representative in respect of matters arising prior
to such time, and shall inure to the benefit of the heirs, executors,
administrators and personal representatives of such a person.

     11.9 Reliance on Provisions. Each person who shall act as an indemnified
representative of the Company shall be deemed to be doing so in reliance upon
the rights of indemnification, contribution and advancement of expenses provided
by this Section.

12.  DISSOLUTION AND TERMINATION.

     12.1 Dissolution. The Company shall be dissolved upon the occurrence of any
of the following events (each, a "Dissolution Event"):

          12.1.1 By the consent of all Members;

          12.1.2 Upon the sale by the Company of all or substantially all of its
     assets;

          12.1.3 Upon the entry of a decree of judicial dissolution under
     ss.18-802 of the Act; or

          12.1.4 Upon exercise by the Other Members of their right under Section
     12.2.3 to cause a liquidation of the Company.

     12.2 Earlier Termination By Buyout. If, at any time during the Term of this
Agreement, any Member (the "Terminating Member") desires to terminate its
Interest in the Company, the Terminating Member shall so notify the other Member
(the "Other Member"), and the following options (the "Buyout Options") shall be
pursued in the following manner and order:

          12.2.1 Procedure. The Terminating Member may elect to first proceed
     under Buyout Option #1. If pursuit of Buyout Option #1 fails to terminate a
     Member's Interest in the Company and interest in this Agreement, the
     Terminating Member may then next proceed under Buyout Option #2. Proceeding
     under Buyout Option #2 will necessarily result in the termination of the
     Terminating Member's Interest in the Company and its interest in this
     Agreement, unless the Terminating Member does not give notice of the offer
     referred to in the second sentence of Section 12.2.3 (which describes
     Buyout Option #2) or does not complete its sale to a third party purchaser
     within the 90 day time period specified in Section 12.2.3 In the event such
     notice is not so given or such sale is not completed within the 90 day time
     period, then at the expiration of the one-year period, the Buyout Options
     shall again be available to any Member in the manner specified in this
     Section 12.2.


                                       33

<PAGE>


          12.2.2 Buyout Option #1: Among the Members. The Terminating Member
     shall negotiate in good faith with the Other Member to sell not less than
     all the Terminating Member's Interest in the Company to the Other Member,
     or to buy not less than all the Other Member's Interest in the Company, at
     a price and on terms to be mutually agreed upon. This Buyout Option shall
     continue to be available to the Terminating Member until the occurrence of
     either of the following: (i) negotiations have not commenced or, if
     commenced, have not resulted in a written agreement signed by all parties
     within 120 days following the Terminating Member's notice described above;
     or (ii) all of the Members mutually agree in writing to omit this Buyout
     Option. Upon the cessation of availability of this Buyout Option, the
     Terminating Member may then elect to proceed under Buyout Option #2. If the
     Terminating Member and Other Member agree to a buyout under this Section
     12.2.2, the Interest of the Terminating Member in the Company and its
     interest in this Agreement will terminate upon the closing of such buyout
     or as otherwise provided in the buyout agreement.

          12.2.3 Buyout Option #2: Terminating Member's Offer and Liquidation
     Right. The Terminating Member may, subject to this Section 12.2.3, seek a
     third party purchaser of not less than all of its Interest in the Company.
     The Terminating Member shall first offer to sell not less than all of its
     Interest in the Company to the Other Member on the terms and conditions set
     forth in such offer ("Offer Terms"). The Other Member shall have the
     option, exercisable by notice to the Terminating Member given within 60
     days after receipt of the Offer Terms, to purchase the Terminating Member's
     Interest on the Offer Terms ("Purchase"). If the Other Member accepts such
     offer, the Interest of the Terminating Member in the Company and its
     interest in the Agreement will terminate upon the closing of the Purchase.
     If the Other Member does not exercise its Purchase option, the Terminating
     Member shall have the right to sell not less than all of its Interest in
     the Company to a third party on terms and conditions no more favorable to
     the third party than the Offer Terms within 90 days after the expiration of
     such 60 day period, provided that the Other Member shall have the right,
     exercisable by notice to the Terminating Member given within 15 days after
     the expiration of such 60-day period, to cause a liquidation of the Company
     pursuant to Section 12.7. This Buyout Option shall continue to be available
     to the Terminating Member until the occurrence of any of the following: (i)
     the Terminating Member has not completed its sale to a third party
     purchaser within the specified 90 day time period; (ii) the Other Member
     has exercised its right to cause a liquidation of the Company; (iii) the
     parties have agreed to the Offer Terms; or (iv) all of the Members agree in
     writing to omit this Buyout Option #2.

     12.3 Earlier Termination for Cause: Breach.

          12.3.1 Grounds. Any Member shall have the right to terminate another
     Member's rights and Interest in the Company on 45 days written notice, if
     it so elects, in the event the other Member commits a material breach of
     any of its obligations under this Agreement, and has not cured such breach
     within 90 days after such notice is given or, if such breach is not
     susceptible of cure within such period, has not commenced and continued
     appropriate steps within such period to cure such breach as soon as
     practicable.

          12.3.2 Procedure by Forced Sale. In the event the non-breaching Member
     elects to terminate the breaching Member's right and Interest in the
     Company pursuant to this Section 12.3.2, it shall have the right to require
     the breaching Member to sell its entire Interest in the


                                       34

<PAGE>


     Company to it at a price equal to product of the book value of the tangible
     assets of the Company multiplied by the breaching Member's Percentage
     Interest, less the cost of curing the breach, but in no event less than
     zero.

          12.3.3 Preservation of Remedies. Nothing in this Section 12.3.3 is
     intended to preclude or in any way restrict any other action for damages
     and/or injunctive relief which may be available to the non-breaching Member
     or to the Company against the breaching Member.

          12.3.4 Payment for Breaching Member's Interest. In the event the
     breaching Member's rights and Interest in the Company are terminated
     pursuant to this Section 12.3.4, no payment shall be made by the
     non-breaching Member to the breaching Member for the latter's Interest in
     the Company until all contractual obligations of the breaching Member to
     the Company have been fully performed.

          12.3.5 No Waiver. Failure of the non-breaching Member to elect to
     terminate the other Member's rights and Interest in the Company in the
     event of a material breach by the other Member shall not constitute a
     waiver by the non-breaching Member of its right to terminate the other
     Member's rights and Interest in the Company in the event of any subsequent
     material breach by the other Member.

     12.4 Closing of Buyout or Termination. The place of the closing of any sale
under this Section 12 shall be the principal office of the purchaser or as
otherwise mutually agreed by the Members. The date of such closing (the
"Termination Closing Date") shall be as mutually agreed upon but in no event
shall such date be later than 30 days after the date the Other Member has
exercised its right to purchase the Interest of the Terminating Member or as
otherwise agreed in the agreement of sale executed by the Terminating Member and
the purchaser subject only to such extension of the Termination Closing Date as
the parties may agree upon in order to finalize the transaction.

     12.5 Transfer of Interest, Properties and Rights. All Interests, properties
and rights to be transferred pursuant to this Section 12 shall be transferred by
proper bills of sale and other instruments of conveyance, assignment,
endorsement or transfer. From time to time after such sale, the selling Member,
without the payment of any further consideration by the buying Member, shall
execute and deliver such further instruments of conveyance, assignment and
transfer and take such other action as counsel for the buying Member may
reasonably request in order to convey and transfer more effectively such
property and rights. The buying Member or Company, as applicable, shall be
responsible for the payment of taxes, filing fees and other related charges
(other than seller's attorneys' fees, seller's income taxes, sales taxes, and
appraisal fees incurred pursuant to Section 12.2.3) resulting from any transfer
pursuant to this Section 12.

     12.6 Activities of the Company Pending Liquidation. Upon the occurrence of
a Dissolution Event, the continuing operation of the Company's business shall be
confined to those activities reasonably necessary to wind up the Company's
affairs, discharge its obligations, and preserve and distribute its assets.

     12.7 Winding Up and Liquidation.


                                       35

<PAGE>


          12.7.1 Upon dissolution of the Company, the Management Committee or a
     liquidator or liquidating committee selected by the Management Committee
     (the "Liquidator") shall be responsible for the winding up of the affairs
     of the Company and the distribution of its assets. In connection with a
     winding up of the affairs of the Company, the Liquidator shall cause an
     accounting to be made of the assets and liabilities of the Company. If any
     liability is contingent or uncertain in amount, a reserve will be
     established in such amount as the Liquidator deems reasonably necessary.
     Upon satisfaction or other discharge of such contingency, the amount of the
     reserve not required, if any, will be distributed as provided in this
     Section 12.7.

          12.7.2 The Liquidator shall be entitled to receive such compensation
     for its services as may be approved by the Management Committee. The
     Liquidator shall agree not to resign at any time without fifteen (15) days'
     prior written notice and may be removed at any time, with or without cause,
     by notice of removal signed by the Management Committee. Upon dissolution,
     removal or resignation of the Liquidator, a successor and substitute
     Liquidator (who shall have and succeed to all rights, powers and duties of
     the original Liquidator) shall within thirty (30) days thereafter be
     selected by the Management Committee. The right to appoint a successor or
     substitute Liquidator in the manner provided herein shall be recurring and
     continuing for so long as the functions and services of the Liquidator are
     authorized to continue under the provisions hereof, and every reference
     herein to the Liquidator will be deemed to refer also to any such successor
     or substitute Liquidator appointed in the manner herein provided. Except as
     expressly provided in this Section 12, the Liquidator appointed in the
     manner provided herein shall have and may exercise, without further
     authorization or consent of any of the Members, all of the powers conferred
     upon the Liquidator under the terms of this Agreement (but subject to all
     of the applicable limitations, contractual and otherwise, upon the exercise
     of such powers) to the extent necessary or desirable in the good faith
     judgment of the Liquidator to carry out the duties and functions of the
     Liquidator hereunder for and during such period of time as shall be
     reasonably required in the good faith judgment of the Liquidator to
     complete the winding up and liquidation of the Company as provided for
     herein.

          12.7.3 The Liquidator shall liquidate the assets of the Company and
     apply and distribute the proceeds of such liquidation in the order of
     priority set forth in Section 12.8, unless otherwise required by mandatory
     provisions of applicable law.

          12.7.4 The Liquidator shall be authorized to sell any, all or
     substantially all of the assets of the Company for deferred payment
     obligations, and to hold, collect and otherwise administer any such
     obligations or any other deferred payment obligations held or acquired as
     assets of the Company.

          12.7.5 A reasonable time, including, without limitation, any time
     required to collect deferred payment obligations, shall be allowed for the
     orderly liquidation of the assets of the Company and the discharge of
     liabilities to creditors so as to enable the Liquidator to reasonably
     minimize any losses attendant upon the liquidation.

     12.8 Distribution of Assets.

          12.8.1 In the event of a dissolution of the Company, upon the winding
     up of the Company, its assets shall be distributed in the following manner
     and order of priority:


                                       36

<PAGE>


               12.8.1.1 First, to creditors, including without limitation
          Members and Managers who are creditors, to the extent otherwise
          permitted by law, in satisfaction of liabilities of the Company
          (whether by payment or the making of reasonable provision for payment
          thereof) other than liabilities for which reasonable provision for
          payment has been made;

               12.8.1.2 Second, to the establishment of any reserves as the
          Liquidator may deem reasonably necessary for contingent, conditional
          or unmatured claims or obligations of the Company arising out of or in
          connection with the Company or its liquidation. Such reserves shall be
          held by the Liquidator for the purpose of disbursing such reserves in
          payment of any of the aforementioned contingencies, and, as soon as
          practicable, to distribute the balance thereafter remaining in the
          manner provided in the following subdivisions of this Section 12.8;
          and

               12.8.1.3 Third, to the Members in proportion to the positive
          balances of their respective Capital Accounts, as determined after
          taking into account all adjustments to such Capital Accounts for the
          Fiscal Year of the Company during which such distribution occurs as
          promptly as practicable, but in any event within the time required by
          Treasury Regulations Section 1.704-1(b)(2)(ii)(b)(2).

          12.8.2 The Company following dissolution shall pay or make reasonable
     provision to pay all claims and obligations, including all contingent,
     conditional or unmatured claims and obligations, known to the Company and
     all claims and obligations which are known to the Company but for which the
     identity of the claimant is unknown. If there are sufficient assets, such
     claims and obligations shall be paid in full and any such provision for
     payment made shall be made in full. If there are insufficient assets, such
     claims and obligations shall be paid or provided for according to their
     priority and, among claims and obligations of equal priority, ratably to
     the extent of assets available therefor. Any remaining assets shall be
     distributed as provided in Subsection 12.8.1. Any Liquidator winding up the
     affairs of the Company who has complied with this Section shall not be
     personally liable to the claimants of the dissolved Company by reason of
     such person's actions in winding up the Company.

     12.9 Cancellation of Certificate. The Certificate of the Company shall be
canceled upon the dissolution and the completion of winding up of the Company.

13.  COVENANTS NOT TO COMPETE.

     13.1 Mutual Covenant Not to Compete. Each of Neose and MSPC agrees that,
while it is a Member, neither it nor any of its direct or indirect subsidiaries
will, directly or indirectly, engage in, have any equity or profit interest in,
make any loan to or for the benefit of, guaranty the repayment of any funds by,
or render services to, or license any Information to, any business conducting
operations in the Territory which are competitive with the business activities
of the Company, including without limitation the development, production and
commercialization of products in the Field, provided that nothing herein shall
be deemed to prohibit either Neose or MSPC from buying compounds from a third
party not then produced by the Company.

     13.2 Covenants Not to Compete Upon Sale or Termination. Any Member selling
its Interest in the Company and its interest in this Agreement under Section
12.2 or 12.3 will not, for a period of 5 years from the date of such sale or
termination, directly or indirectly, engage in, have any equity or profit
interest in, make any loan to or for the benefit of, guaranty the repayment of
any funds by, or render services to, or license any Information to, any business
conducting operations in the Territory which are competitive with the business
activities of the Company, including without limitation the development,
production and commercialization of products in the Field as the Field exists on
the date of sale or termination.

14.  BOOKS; REPORTS TO MEMBERS; TAX ELECTIONS.

     14.1 Books and Records.

          14.1.1 The Company shall maintain separate books of account which
     shall show a true and accurate record of all costs and expenses incurred,
     all charges made, all credits made and received and all income derived in
     connection with the conduct of the Company and the operation of its
     business, and, to the extent inconsistent therewith, in accordance with

     expense) as may be established by the Management Committee, to obtain from
     the Company from time to time upon reasonable demand for any purpose

          has agreed to contribute in the future, and

     Management Committee deems reasonable, any information which the Management
     Committee reasonably believes to be in the nature of trade secrets or other
     information the disclosure of which the Management Committee in good faith
     believes is not in the best interest of the Company or could damage the
     Company or its business or which the Company is required by law or by
     agreement with a third party to keep confidential.

          14.1.6 The Company may maintain its records in other than a written
     form if such form is capable of conversion into written form within a
     reasonable time.

          14.1.7 Any demand by a Member under this Section shall be in writing
     and shall state the purpose of such demand.

Year, the Company shall supply to each Member all information necessary and
appropriate to be included in each Member's income tax returns with respect to
that Fiscal Year.

Year, the Company shall cause to be prepared, and each Member furnished with,

financial statements of the Company prepared in accordance with GAAP, and, to

     14.5 Tax Matters Member.

          14.5.1 The Management Committee shall, from time to time, appoint a
     "Tax Matters Member" within the meaning of Section 6231(a)(7) of the Code
     for so long as it is not the subject of bankruptcy or similar proceedings
     and otherwise is entitled to act as the Tax Matters Member. The initial Tax
     Matters Member shall be MSPC. The Tax Matters Member may file a designation
     of itself as such with the IRS. The Tax Matters Member shall (i) furnish to
     each Member affected by an audit of the Company income tax returns a copy
     of each notice or other communication received from the IRS or applicable
     state authority, (ii) keep each Member informed of any administrative or
     judicial proceeding, as required by Section 6223(g) of the Code, and (iii)
     allow each Member an opportunity to participate in all such administrative
     and judicial proceedings. The Tax Matters Member shall take such action as
     may be reasonably necessary to constitute the other Member a "notice
     Member" within the meaning of Section 6231(a)(8) of the Code, provided that
     the other Member provides the Tax Matters Member with the information that
     is necessary to take such action.

          14.5.2 The Company shall not be obligated to pay any fees or other
     compensation to the Tax Matters Member in its capacity as such. However,
     the Company shall reimburse the expenses (including without limitation
     reasonable attorneys' and other professional fees) incurred by the Tax
     Matters Member in such capacity. Each Member who elects to participate in
     Company administrative tax proceedings shall be responsible for its own
     expenses incurred in connection with such participation. In addition, the
     cost of any adjustments to a Member and the cost of any resulting audits or
     adjustments of a Member's tax return shall be borne solely by the affected
     Member.

          14.5.3 The Company shall indemnify and hold harmless the Tax Matters
     Member from and against any loss, liability, damage, cost or expense
     (including without limitation reasonable attorneys' fees) sustained or
     incurred as a result of any act or decision concerning Company tax matters
     and within the scope of such Member's responsibilities as Tax Matters
     Member, so long as such act or decision was not the result of gross
     negligence, fraud, bad faith or willful misconduct by the Tax Matters
     Member. The Tax Matters Member shall be entitled to rely on the advice of
     legal counsel as to the nature and scope of its responsibilities and
     authority as Tax Matters Member, and any act or omission of the Tax Matters
     Member pursuant to such advice shall in no event subject the Tax Matters
     Member to liability to the Company or either Member.

     14.6 Tax Audits/Special Assessments. If the federal tax return of either
the Company or an individual Member with respect to an item or items of Company
income, loss, deduction, etc., potentially affecting the tax liability of the
Members generally is subject to an audit by the IRS, the Management Committee
may, in the exercise of their business judgment, determine that it is necessary
to contest proposed adjustments to such return or items. If such a determination
is made, the Management Committee will finance the contest of the proposed
adjustments out of the Net Cash Flow.

     14.7 Tax Elections. The Company will elect to amortize organizational
costs. In the event of the distribution of property, upon the transfer of an
Interest in the Company or the issuance of an Interest in the Company to a new
Member, the Company shall, at the request of the transferor Member, file an
election, in accordance with applicable Treasury Regulations, to cause the
basis of


                                       40

<PAGE>


the Company's property to be adjusted for federal income tax purposes as
provided by Sections 734, 743 and 754 of the Code. The determination whether to
make and file any such election shall be made by the Management Committee in
their sole discretion.

15.  CONFIDENTIALITY.

     15.1 Non-disclosure. Each Member agrees to keep the other Member's
Information and the Company's Information in strict confidence and not to
disclose or otherwise use the other Member's Information or the Company's
Information for any purpose other than for purposes of the Company. The Company
agrees to keep the Members' Information and Company's Information in strict
confidence and not to disclose or otherwise use such Information for any purpose
other than for purposes of the Company. Accordingly, each Member and the Company
agree to treat the Information which it receives as it would its own proprietary
Information and to take all reasonable precautions to prevent the unauthorized
disclosure to any third party of the Information which it receives hereunder;
provided, however, that nothing herein shall prevent either Member from
disclosing the other Member's Information to an Affiliate; further provided that
the Affiliate accepts the Information under the same obligations as stated
herein.

     15.2 Procedure to Deem Confidential. In order to be deemed confidential,
the Information shall be supplied to the receiving Member in written form and
identified as being confidential or, if disclosed orally, shall be confirmed in
writing within thirty (30) days of its oral disclosure. All such Information
properly identified as confidential shall at the disclosing Member's request be
returned to it except that one (1) copy shall be retained by counsel for the
receiving Member to ensure compliance hereunder. The foregoing procedure shall
also apply to all Information exchanged by the parties prior to the execution of
this Agreement, to which Information this Section 15 shall also apply.

     15.3 Exceptions. The above notwithstanding, the receiving Member's
obligation of confidence with respect to the Information disclosed hereunder
shall not include:

          (a) Information which, at the time of disclosure to the receiving
     Member is published, known publicly or is otherwise in the public domain;

          (b) Information which, after disclosure to the receiving Member is
     published or becomes known publicly or otherwise becomes part of the public
     domain, through no fault of the receiving Member;

          (c) Information which, prior to the time of disclosure to the
     receiving Member, is known to the receiving Member, as evidenced by its
     written records;

          (d) Information which has been or is disclosed to the receiving Member
     in good faith by a third party who was not, or is not, under any obligation
     of confidence or secrecy to the other Member at the time said third party
     discloses to the receiving Member and without requiring any further
     restrictions on disclosure; and


                                       41

<PAGE>


          (e) Information which is independently developed by or on behalf of
     the receiving Member, without reliance on the Information received
     hereunder.

     15.4 Public Disclosure. Except as permitted under Section 18.10, the above
provisions notwithstanding, each Member agrees to keep in strict confidence and
not to disclose the identity, interest and participation of the other Member in
the Company or any of the material terms of this Agreement.

     15.5 No Third Party Obligations. Each Member represents that it is under no
obligation to any third party that would interfere with its disclosing
Information to the other Member and, further, that any Information which it
transmits or has transmitted or otherwise discloses or has disclosed to the
other party is not Information with respect to which the disclosing party is
under any obligation to keep confidential or which the disclosing party knows to
be the proprietary property of any third party.

     15.6 No Right or License. No right or license to use any Information
disclosed hereunder, either express or implied, is granted by either party to
this Agreement, other than the right to use such Information for the parties'
own activities in furtherance of the activities of the Company.

     15.7 Duration. The obligations of confidentiality and nonuse set forth
herein shall remain in effect for five (5) years after the termination of this
Agreement.

16.  DISPUTE RESOLUTION.

     16.1 Arbitration. Any controversy, dispute or claim among the parties
arising out of or relating to (i) the validity, inducement or breach of or the
interpretation of any provision of this Agreement, (ii) the interpretation or
application of law, or (iii) the ownership of any intellectual property that
cannot be amicably settled by the parties, shall be decided by arbitration in
accordance with the rules of the American Arbitration Association for Commercial
Arbitration in effect at the time the dispute arises, unless the parties hereto
mutually agree otherwise. To the extent such rules are inconsistent with this
provision, this provision will control.

          16.1.1 Any demand for arbitration must be made in writing to the other
     party.

          16.1.2 There will be a panel of three arbitrators, one selected by
     MSPC, one selected by Neose, and one selected by mutual agreement of the
     arbitrators selected by MSPC and Neose. If the arbitrators selected by MSPC
     and Neose cannot agree on a third arbitrator within thirty (30) days, then
     the American Arbitrators Association ("AAA") shall select the third
     arbitrator. Any arbitration involving patent rights, other intellectual
     property rights or intellectual property shall be heard by arbitrators who
     are experts in such areas. Otherwise, the arbitrator shall be (i) an
     attorney specializing in corporate and finance law or business litigation
     who has at least 15 years of experience with a law firm of over 25 lawyers
     or (ii) a former judge of a court of general jurisdiction.

          16.1.3 The arbitration shall be held in Wilmington, Delaware, or such
     other place as the parties agree. The arbitrators shall apply the
     substantive law of Delaware, without regard to conflicts of laws and except
     that the interpretation and enforcement of this arbitration provision shall


                                       42

<PAGE>


     be governed by the Federal Arbitration Act. Within thirty (30) days after
     initiation of arbitration, the parties shall reach agreement upon and
     thereafter follow procedures assuring that the arbitration will be
     concluded and the award rendered within no more than six months from
     selection of the arbitrator. Failing such agreement, the AAA will design
     and the parties will follow such procedures. The arbitrators shall render a
     written opinion setting forth findings of fact and conclusions of law.

          16.1.4 Except as provided in Section 16.1.5, neither party shall have
     the right independently to seek recourse from a court of law or other
     authorities in lieu of arbitration, but each party has the right before or
     during the arbitration to seek and obtain from the appropriate court
     provisional remedies to avoid irreparable harm, maintain the status quo or
     preserve the subject matter of the arbitration. There shall be a
     stenographic record of the proceedings. The decision of the arbitrators
     shall be made by majority vote and shall be final and binding upon both
     parties. The arbitrators shall render a written opinion setting forth
     findings of fact and conclusions of law.

          16.1.5 The parties hereby consent to the jurisdiction of the Federal
     District Court for the District of Delaware for the enforcement of these
     provisions and the entry of judgment on any award rendered hereunder. If
     the arbitrators' award exceeds $5,000,000, the court may, upon motion of a
     party, vacate, modify or correct any award but only to the extent the
     arbitrators' findings of fact or conclusions of law are clearly erroneous.
     It is the intention of the parties that the court shall undertake the same
     review as if it were a Federal appellate court reviewing a district court's
     findings of fact and conclusions of law rendered after a bench trial.
     Should such court for any reason lack jurisdiction, any court with
     jurisdiction shall enforce this Section and enter judgment on any award.

          16.1.6 Reasonable expenses of the arbitration shall be borne equally
     by the parties. Each party shall bear the expenses of its counsel and other
     experts.

          16.1.7 EACH PARTY HERETO WAIVES ITS RIGHT TO TRIAL OF ANY ISSUE BY
     JURY. THE ARBITRATOR SHALL NOT AWARD ANY PARTY PUNITIVE, EXEMPLARY OR
     CONSEQUENTIAL DAMAGES, AND EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT
     TO SEEK SUCH DAMAGES, PROVIDED THAT A PARTY MAY BE AWARDED CONSEQUENTIAL
     DAMAGES FROM THE OTHER IF THE FORSEEABILITY AND AMOUNT OF SUCH DAMAGES ARE
     PROVEN BY CLEAR AND CONVINCING EVIDENCE.

     16.2 Disputes. To the extent that any dispute or difference arises between
the parties or between a party and the Company during the Term of this
Agreement, other than a dispute or difference subject to Section 16.1, then the
dispute shall be referred for resolution, if possible, to the Chief Executive
Officer of Neose and the President of MSPC.

17.  INVESTMENT REPRESENTATION.

     17.1 Investment Purpose. Each Member represents and warrants to the Company
and to each other Member that it has acquired the Interest in the Company for
such Member's own account, for investment only and not with a view to the
distribution thereof, except to the extent provided in or contemplated by this
Agreement.


                                       43

<PAGE>


     17.2 No Registration. The Interests in the Company have not been registered
with the Securities and Exchange Commission under the 1933 Act or under similar
laws of any states in reliance upon exemptions under those acts. The sale or
other disposition of the Interests in the Company is restricted as provided in
this Agreement.

18.  MISCELLANEOUS.

     18.1 Binding Effect. This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns. If a
Member who is an individual dies or a court of competent jurisdiction adjudges
him to be incompetent to manage his person or his property, the executor,
administrator, guardian, conservator or other legal representative of the Member
may exercise all of the rights of the Member for the purpose of settling such
Member's estate or administering such Member's property, including the power the
Member had to give an assignee the right to become a Member. If a Member is a
corporation, trust or other entity and is dissolved or otherwise terminated, the
powers of that Member may be exercised by its legal representatives or
successors. The successor of a Member shall succeed to the right of the Member
to receive allocations and distributions hereunder, and may be admitted as a
Member in accordance with the provisions of Section 10.2, but shall not be
deemed a Member, and shall not be entitled to voting rights hereunder, unless
and until so admitted.

     18.2 Entire Agreement. This Agreement constitutes the entire agreement
between the parties hereto concerning the subject matter hereof and any
representation, promise or condition in connection therewith, not incorporated
herein, shall not be binding upon either party. Before signing this Agreement
the parties have had numerous conversations, including preliminary discussions,
formal negotiations and informal conversations at meals and social occasions,
and have generated correspondence and other writings, in which the parties
discussed the transaction which is the subject of this Agreement and their
aspirations for success. In such conversations and writings, individuals
representing the parties may have expressed their judgments and beliefs
concerning the intentions, capabilities, and practices of the parties, and may
have forecasted future events. The parties recognize that such conversations and
writings often involve an effort by both sides to be positive and optimistic
about the prospects for the transactions. However, it is also recognized, that
all business transactions contain an element of risk, as does the transaction
contemplated by this Agreement, and that it is normal business practice to limit
the legal obligations of contracting parties to only those promises and
representations which are essential to their transaction so as to provide
certainty as to their respective future rights and remedies. Accordingly, this
Agreement is intended to define the full extent of the legally enforceable
undertakings of the parties hereto, and no promise or representation, written or
oral, which is not set forth explicitly in this Agreement is intended by either
party to be legally binding. This Agreement expressly supersedes that certain
Confidential Disclosure Agreement effective as of September 12, 1996 between the
parties and the Joint Development Agreement. Both parties acknowledge that in
deciding to enter into this Agreement and to consummate the transaction
contemplated hereby neither has relied upon any statements or representations,
written or oral, other than those explicitly set forth herein.

     18.3 Amendments. The Certificate and this Agreement may not be amended
except by the written agreement of all of the Members.


                                       44

<PAGE>


     18.4 Choice of Law. Notwithstanding the place where this Agreement may be
executed by any of the parties hereto, the parties expressly agree that all the
terms and provisions hereof shall be construed under the laws of the State of
Delaware (without regard to any conflicts of law principles.) Each of the
Members hereby expressly submits itself generally and unconditionally to the
personal jurisdiction of any United States or state court for any matter not
resolved pursuant to Section 16 hereof.

     18.5 Notices. Except as otherwise provided in this Agreement, any notice,
demand or communication required or permitted to be given by any provision of
this Agreement shall be in writing and shall be deemed to have been sufficiently
given or served for all purposes if delivered personally or sent by facsimile
transmission (with answer back received) or overnight express to the party or to
an executive officer of the party to whom the same is directed or, if sent by
registered or certified mail, postage and charges prepaid, addressed to the
Member's address:

and to the Company at its principal place of business, or at such other address
as a Member may direct in writing.

     18.6 Headings. The headings of the Sections of this Agreement are for
convenience of reference only and are not to be considered in construing the
terms and provisions of this Agreement.

     18.7 Pronouns. All pronouns shall be deemed to refer to the masculine,
feminine, neuter, singular or plural, as the identity of the person or persons,
firm or corporation may require in the context thereof.

     18.8 Waivers. The failure of any party to seek redress for violation of or
to insist upon the strict performance of any covenant or condition of this
Agreement shall not prevent a subsequent act, that would have originally
constituted a violation, from having the effect of an original violation.

     18.9 Severability. If any provision of this Agreement or its application to
any person or circumstance shall be invalid, illegal or unenforceable to any
extent, the remainder of this Agreement and its application shall not be
affected and shall be enforceable to the fullest extent permitted by law.

     18.10 Publicity. No press release or other public announcement related to
this Agreement or the Company or the transactions contemplated hereby shall be
issued by any Member without the prior approval of the Management Committee,
except that any Member may make such public disclosure which it believes in good
faith to be required by law or by the terms of any listing


                                       45

<PAGE>


agreement with a securities exchange (in which case such Member shall make a
reasonable effort to consult with the Members prior to making such disclosure).

     18.11 No Third Party Beneficiaries. None of the provisions of this
Agreement shall be for the benefit of or enforceable by any person other than
the Members and their respective successors and assigns.

     18.12 Interpretation. It is the intention of the Members that, during the
term of this Agreement, the rights of the Members and their
successors-in-interest shall be governed by the terms of this Agreement, and
that the right of any Member or successor-in-interest to assign, transfer, sell
or otherwise dispose of any Interest in the Company shall be subject to
limitations and restrictions set forth in this Agreement.

     18.13 Further Assurances. Each Member shall execute all such certificates
and other documents and shall do all such other acts as the Management Committee
may reasonably deem appropriate to comply with (a) the requirements of law for
the formation of the Company, (b) any laws, rules, Treasury Regulations and
third-party requests relating to the acquisition, operation or holding of the
property of the Company or (c) the intent and purposes of this Agreement.

     18.14 Counterparts. This Agreement may be executed in counterparts, each of
which shall be deemed an original, but all of which taken together shall
constitute one and the same instrument. This Agreement may be signed and
delivered to the other party by facsimile transmission and such transmission
shall be deemed to be a valid signature.

     18.15 Survival of Rights and Obligations. In the event of a termination of
this Agreement, the rights and obligations of the parties during the Term of
this Agreement under Sections 7.5, 7.9, 8, 11, 12.5, 12.6, 12.7, 12.8, 12.9, 13,
14, 15, 16 and 18.4 shall survive and continue in full force and effect.

     18.16 Representations and Warranties. Each party represents and warrants to

right and authority to extend the rights granted in this Agreement, (b) it has

are bound or (ii) violate any provision of law, statute, rule or regulation or
any ruling, writ, injunction, order, judgment or decree of any court,

          Wyeth-Ayerst, its Affiliates or sublicensees, as appropriate, to Third

          United States, for (i) reasonable trade, cash and quantity discounts
          or rebates (other than price discounts granted at the time of sale),
          reasonable service allowances and reasonable required agent's
          commissions, if any, allowed or paid, (ii) credits or allowances
          actually given or made for rejection or return of, previously sold

          distributed for use in combination with or as a component of another
          product or products (a "Combination Product"), the calculation of Net
          Sales from such Combination Product would be determined above by a

          Product in such Combination Product, and the denominator of which is
          the fair market value of the Combination Product. In the event that
          Wyeth-Ayerst would sell Product together with other products of
          Wyeth-Ayerst to Third Parties, and the price attributable to the

          Parties for the reporting period in which sales occur (such sales to
          be excluded from the calculation of the average price of "arms length"
          sales), Net Sales for any such sales would be average price of "arms
          length" sales by Wyeth-Ayerst to Third Parties during the reporting
          period in which such sales relate.

     1.20 "Pediatric Nutritional Compositions" shall mean infant and pediatric

          which are useful as a food, a source of nutrition, the sole source of
          nutrition or as a nutritional supplement.

                shall be held in person, or otherwise by video or telephone
                conference. When held in person the location of the meeting
                shall alternate between Wyeth-Ayerst's facilities and Neose's
                facilities. The chairperson shall prepare an agenda for the
                meeting, and shall include in the agenda items proposed by
                Neose's representatives. Additional participants may be invited
                by any member to attend meetings where appropriate (e.g.,
                outside consultants). Such additional participants shall have no
                vote. Minutes of each meeting of the JDC shall be exchanged for
                review and comment by the members. Thereafter, they shall be
                signed by the chairperson and distributed to each of the
                parties. Each party shall be responsible for the expense
                incurred by its representatives in attending such meetings.

          2.2.4 Voting. The JDC shall make decisions by majority vote, with at

                required majority decision cannot be found and all the members
                of each party take the same opposing positions in a matter which
                either party deems to be of importance, the matter shall be
                handled pursuant to Section 2.2.6 hereof. Voting by proxy is
                permissible. Urgent matters may be decided by unanimous vote of
                the chairperson and a representative of Neose.

          2.2.5 Role of Chairperson. Except as explicitly set forth herein, in
                no event shall the chairperson of the JDC have any additional
                power or responsibilities beyond those delegated to such person
                by such person's membership on the JDC. Without limiting the
                foregoing, it is understood that, except as a voting member of
                the JDC, the chairperson shall not have the power to control or
                dictate decisions or to veto any decisions reached by the
                committee under the decision making process set forth in Section
                2.2.4 hereof.

                any reason in whole or in part, or with respect to any given
                country or countries, each sublicense shall automatically
                terminate on the same basis as this Agreement, unless otherwise

                Wyeth-Ayerst; provided that Neose shall remit to Wyeth-Ayerst
                any amount by which such payments exceed the amounts owed by

          discretion, to convert the license granted hereunder to a
          non-exclusive license on a country by country basis. In the event that
          Wyeth-Ayerst chooses to convert the license to a non-exclusive license
          in more than one (1) country in a given Region, Wyeth-Ayerst can
          choose to convert the license to a non-exclusive license in the entire

                that in the event it enters into a commercial arrangement, with

                Wyeth-Ayerst of the commercial terms of such arrangement and,
                where the terms of such Third Party arrangement, with respect to
                its royalty and manufacturing and supply provisions are, taken
                as a whole, more favorable than the royalty provisions hereunder
                and the Manufacturing and Supply Agreement between Neose and
                Wyeth-Ayerst under the provisions of Section 7.1 hereof,

                Manufacturing and Supply Agreement and the royalties hereunder
                with Neose to contain those terms.

     5.3  Method of Payment of Royalties. Wyeth-Ayerst shall deliver to Neose
          within sixty (60) days of the end of each calendar quarter, a report
          certified by Wyeth-Ayerst as accurate to the best of its ability based
          upon information then available for such calendar quarter, on a
          country-by- country basis: (i) Net Sales of Product in each country;
          (ii) the basis for any adjustments to the royalty payable to Neose for
          the sale of Product in such country; and (iii) the total royalty due
          for the sale of the Product in each such country. The total royalty
          due to Neose during such calendar quarter shall be remitted at the
          time such report is made in accordance with the following:

          (i)   the total royalty due for such calendar quarter shall accompany
                the report for that quarter; (ii) the royalty shall be paid in
                United States dollars; (iii) any currency translations that are
                necessary to calculate the royalty shall be made at the exchange
                rate applicable on the date of payment as used by Wyeth-Ayerst
                for financial accounting purposes in accordance with generally
                accepted accounting principals; and (iv) royalty checks are to
                be made payable to Neose and mailed to the address specified in
                Section 16.5.1 hereof.

     5.4  If by reason of any restrictive exchange laws or regulations,
          Wyeth-Ayerst shall be unable to convert to U.S. dollars amounts
          equivalent to the total royalty due and payable by Wyeth-Ayerst
          hereunder in respect to Products sold for funds other than U.S.
          dollars, Wyeth-Ayerst shall notify Neose promptly with an explanation
          of the circumstances. In such event all royalties due hereunder in
          respect of the transaction so restricted (or the balance thereof due
          hereunder) shall be deferred and paid in U.S. dollars as soon as
          reasonably possible after, and to the extent that such restrictive
          exchange laws or regulations are lifted so as to permit such
          conversion to U.S. dollars, of which lifting Wyeth-Ayerst shall
          promptly notify Neose. At its option, Neose shall have the right to
          request payment, and upon such request Wyeth-Ayerst shall pay or cause
          to be paid, all such amounts or portions thereof as specified by Neose
          in funds other than U.S. dollars as designated by Neose under the
          existing restrictive exchange laws or regulations.

     5.5  Any and all taxes levied on account of royalties paid from a country
          in which a provision is made in the law or by regulation for
          withholding shall be deducted from such royalty paid to Neose
          hereunder and proof of payment of such taxes shall be received and
          reported in the reports described in Section 5.3 hereof.

          figures necessary for verification of payments required to be paid
          hereunder. Wyeth-Ayerst shall and shall cause its Affiliates and/or
          sublicenses to maintain such records for a period of three (3) years
          after the end of the year in which they were generated.

     6.2  Audit by Neose. Neose, through an independent certified public
          accountant reasonably acceptable to Wyeth-Ayerst, shall have the
          right, at its own expense, to access the books and records of
          Wyeth-Ayerst its Affiliates or sublicensees as the case may be, for
          the sole purpose of determining whether a payment under Section 5 has
          become due and the accuracy thereof. Such access shall be conducted
          after reasonable prior written notice to Wyeth-Ayerst and during
          ordinary business hours and shall not be more frequent than once per
          calendar year. Wyeth-Ayerst may require such independent certified
          public accountant to sign a customary confidential disclosure
          agreement prior to permitting such independent certified public
          accountant to have access to its books, records or facilities. The
          parties agree that such independent certified public accountant shall
          disclose to Neose only, for the period covered by such audit, the Net
          Sales of Product in each country, the basis for any adjustments to the
          royalty payable to Neose for the sale of Product in such countrty, and
          the total royalty due for the sale of Product in each such country.
          Neose agrees to keep in strict confidence all information learned in
          the course of such audit, except when it is necessary to reveal such
          information in order to enforce its rights under this Agreement.
          Neose's right to have such records examined shall survive termination
          or expiration of this Agreement. In the event such audit reveals an
          underpayment, Wyeth-Ayerst shall promptly pay to Neose the amount of
          such underpayment. In the event that such audit reveals an
          underpayment of five percent (5%) or more of the amount actually due,
          Wyeth-Ayerst shall also promptly reimburse Neose for the reasonable
          out-of-pocket expenses incurred by Neose in conducting such audit.

     6.3  Record Keeping by Neose. Neose shall keep accurate books and accounts
          of record in connection with the activities conducted by it in
          carrying out

          the Research Program in sufficient detail to verify that the amounts
          received by Neose pursuant to Section 2.6 hereof have been expended in
          accordance with the Research Program. Neose shall maintain such
          records for a period of three (3) years after the end of the last year
          in which funds were received by Neose in accordance with Section 2.6
          hereof.

     6.4  Audit by Wyeth-Ayerst. Wyeth-Ayerst, through an independent certified
          public accountant reasonably acceptable to Neose, shall have the
          right, at its own expense, to access the books and records of Neose
          for the sole purpose of verifying that the amounts received by Neose
          pursuant to Section 2.6 hereof have been expended in accordance with
          the Research Program. Such access shall be conducted after reasonable
          prior written notice to Neose and during ordinary business hours and
          shall not be more frequent than once per calendar year. Neose may
          require such independent certified public accountant to sign a
          customary confidential disclosure agreement prior to permitting such
          independent certified public accountant to have access to its books,
          facilities or records. The parties agree that such independent
          certified public accountant shall disclose to Wyeth-Ayerst only
          whether such amounts were expended in accordance with the Research
          Program. Wyeth-Ayerst agrees to keep in strict confidence all
          information learned in the course of such audit, except when it is
          necessary to reveal such information in order to enforce its rights
          under this Agreement. Wyeth-Ayerst's right to have such records
          examined shall survive termination or expiration of this Agreement.

<PAGE>

          Products by Wyeth-Ayerst hereunder. Upon the expiration of the
          Agreement, Wyeth-Ayerst's license shall become a fully paid-up,
          perpetual, exclusive license in each such country subject only to any
          sublicenses granted by Wyeth-Ayerst, provided that to the extent
          Wyeth-Ayerst has converted the license granted hereunder to
          non-exclusive license pursuant to Section 5.2, such license will be
          non-exclusive.

     7.2  Unilateral Termination by Wyeth-Ayerst. Wyeth-Ayerst shall have the
          right to unilaterally terminate this Agreement, on a country by
          country basis, upon thirty (30) days prior written notice to Neose. In

                (i)   complete toxicology studies of the Final Product within
                      twenty four (24) months after its receipt of sufficient

                (ii)  complete Clinical Studies of Final Product within thirty
                      six (36) months after its receipt of sufficient material
                      from Neose to begin such studies, which material has
                      satisfied the requirements of the toxicology studies
                      conducted in accordance with Section 7.3.1(i) above.

     7.4  Unilateral Termination by Neose - Post Clinical Studies. Neose shall

          country-by-country

                                      -24-

<PAGE>

          basis, upon thirty (30) days prior written notice to Wyeth-Ayerst as
          follows:

                (i)   If Wyeth-Ayerst fails to file for Regulatory Approval in
                      any Major Market within twelve (12) months after
                      completion of Clinical Studies. For purposes of this
                      section, "completion of Clinical Studies" shall mean (a)
                      receipt of a positive outcome from said Clinical Studies
                      based upon standards of infant safety growth and tolerance
                      as established in the protocol for such Clinical Study and
                      (b) the receipt of a final audited report from all
                      Clinical Research Organization in a form reasonably
                      acceptable to Wyeth-Ayerst. The twelve (12) month period
                      referred to herein shall not commence until a Master
                      Regulatory Dossier is completed. It is understood and
                      agreed that the Master Regulatory Dossier shall take up to
                      nine (9) months to complete. Neose agrees to provide its
                      full cooperation in the completion of the Master
                      Regulatory Dossier.

                      (1)  In the event Wyeth-Ayerst does not receive a positive
                           outcome from the Clinical Studies as set forth in
                           Section 7.4 (i)(a) hereof, the JDC shall establish
                           appropriate timelines for conducting a follow-up
                           Clinical Study. In the event Wyeth-Ayerst decides
                           that it shall not conduct a follow-up Clinical Study,
                           or, if after commencing a follow-up Clinical Study,
                           Wyeth-Ayerst fails to complete such study within the
                           timeline established by JDC, Neose may terminate the
                           Agreement on thirty (30) days prior written notice to
                           Wyeth-Ayerst.

                (ii)  If Wyeth-Ayerst does not launch Licensed Product in any
                      Major Market within twelve (12) months after receiving
                      Regulatory Approval in that Major Market.

                                      -25-

<PAGE>

                (iii) If Wyeth-Ayerst does not launch Licensed Product in any
                      single Major Market within eight (8) years from the
                      Effective Date.

     7.5  The parties agree that the JDC shall determine appropriate timelines
          for the completion of the Research Program and the supply of Covered
          Compound by Neose to Wyeth-Ayerst. In the event Neose fails to perform
          under the timelines established by the JDC for the completion of the
          Research Program and the supply of Covered Compounds, all time periods
          set forth in Sections 7.3 and 7.4 hereof shall be extended for a
          period equivalent to Neose's delay in performing under such timelines.

     7.6  Termination for Cause. This Agreement may be terminated upon prior
          written notice by either party at any time during the term of this
          Agreement:

                (i)   for material breach by the other party, which breach
                      remains uncured for sixty (60) days after written notice
                      of said breach is given to the breaching party or, if such
                      breach is not susceptible to cure within such sixty (60)
                      day period, and the breaching party utilizes diligent good
                      faith efforts to cure such breach, the period shall be
                      extended to one hundred twenty (120) days from the date on
                      which the written notice is provided to the breaching
                      party; or

                (ii)  upon the filing or institution of bankruptcy,
                      reorganization, liquidation or receivership proceedings,
                      or upon an assignment of a substantial portion of the
                      assets of the benefit of creditors by the other party, or
                      in the event a receiver or custodian is appointed for such
                      party's business, or if a substantial portion of such
                      party's business is subject to attachment or similar
                      process; provided, however, that in the case of any
                      involuntary bankruptcy proceeding, such right to terminate
                      shall only become effective if the proceeding is not
                      dismissed within sixty (60) days after the filing thereof.

                      Section 7.6(i) hereof, the license granted to Wyeth-Ayerst
                      pursuant to Section 3.1 shall become a fully paid-up,
                      perpetual license in each country of the Territory.

                (ii)  In the event that Neose terminates this Agreement under

                      rights to the Neose Technology shall revert to Neose.

                (iii) In the event that Wyeth-Ayerst terminates this Agreement
                      under Section 7.6(ii) or this Agreement is otherwise
                      terminated under Section 7.6(ii), the parties agree that
                      Wyeth-Ayerst shall retain all rights and licenses granted
                      to it hereunder and the license granted to Wyeth-Ayerst
                      under Section 3.1 hereof shall become a perpetual license
                      under which Wyeth-Ayerst shall remain obligated to pay
                      royalties to Neose as set forth in Section 5 hereof.

                exercise all

                or, if not amenable to copying, detailed descriptions or other
                appropriate embodiments, to the extent feasible, of all such
                intellectual property. If a case is commenced by or against
                Neose under Title 11, Neose (in any capacity, including
                debtor-in-possession) and its successors and assigns (including
                without limitation, a Title 11 Trustee) shall:

                (i)   as Wyeth-Ayerst may elect in a written request,

                           (including embodiments thereof) held by Neose and
                           such successors and assigns or otherwise available to

                      (b)  provide to Wyeth-Ayerst all such intellectual
                           property (including all embodiments thereof) held by

                           available to them; and

                (ii)  not interfere with the rights of Wyeth-Ayerst under this
                      Agreement, or any agreement supplemental hereto, to such
                      intellectual property, including any right to obtain such
                      intellectual property from another entity.

          7.8.2 Rights to Intellectual Property. If a Title 11 case is commenced
                by or against Neose and this Agreement is rejected as provided

                Title 11, then Neose (in any capacity, including
                debtor-in-possession) and its successors and assigns (including,
                without limitation, Title 11 Trustee) shall provide to
                Wyeth-Ayerst all such intellectual property (including all
                embodiments thereof) held by Neose and such successors and -
                assigns, or otherwise available to them, immediately upon
                Wyeth-Ayerst's written request. Whenever Neose or any of its
                successors or assigns provides to Wyeth-Ayerst any of the
                intellectual property licensed hereunder (or any embodiment
                thereof) pursuant to this Section 7.8, Wyeth-Ayerst shall have
                the right to perform the obligations of Neose hereunder with
                respect to such intellectual property, but neither such
                provision nor such performance by Wyeth-Ayerst shall release
                Neose from any such obligation or liability for failing to
                perform it.

          7.8.3 Wyeth-Ayerst's Rights. All rights, powers and remedies of
                Wyeth-Ayerst provided herein are in addition to and not in
                substitution for any and all other rights, powers and remedies
                now or hereafter existing at law or in equity (including,
                without limitation, Title 11) in the event of the commencement
                of a Title 11 case by or against Neose. Wyeth-Ayerst, in
                addition to the rights, powers and remedies expressly provided
                herein, shall be entitled to exercise all other such rights and
                powers and resort to all other such remedies as may now or
                hereafter exist at law or in equity (including, without
                limitation, Title 11) in such event. The parties agree that they
                intend the foregoing Wyeth-Ayerst rights to extend to the
                maximum extent permitted by law, including, without limitation,
                for purposes of Title 11:

                (i)   the right of access to any intellectual property of Neose
                      or any Third Party with whom Neose contracts to perform an

                      case of a Third Party, which is necessary for the
                      development, registration, manufacturing and marketing of
                      Covered Compound and/or Products; and

                (ii)  the right to contract directly with any Third Party
                      described in (i) above to complete the contracted work.

     7.9  Prior Obligations. Termination or expiration of this Agreement shall
          not operate to deprive either party of any rights or remedies either
          at law or in equity or to relieve either party of any of its
          obligations incurred prior to the date of such termination or
          expiration.

          2.7, 6, 11, 12, 13.1, 14, 16.5, 16.6 and 16.10 shall survive

          13.1.1 Patent Procurement. Neose and Wyeth-Ayerst shall each disclose
                 to the other and discuss any inventions and discoveries arising
                 during the term of this Agreement and the desirability of
                 filing one or more patent applications covering such inventions
                 or discoveries. The party owning the invention or discovery
                 shall make the final decision with respect to any such filings
                 and shall have the right to select patent counsel and to take
                 other actions as appropriate to prepare, file, prosecute, and
                 maintain patent protection with respect to its inventions and
                 discoveries arising under this Section 13.1. With respect to
                 jointly owned inventions, the parties shall meet to determine
                 in which countries, if any, the patent applications claiming
                 such joint inventions and discoveries should be filed. In the
                 event that either party does not wish to share in the expenses
                 of both filing and prosecuting patent applications claiming
                 such joint inventions and discoveries in any country of the
                 Territory, such party shall promptly assign or cause to be
                 assigned to the other party all of its right, title, and
                 interest in and to such joint inventions and discoveries and
                 thereafter, such joint inventions and discoveries shall be
                 treated as an invention or discovery solely owned by the other
                 party for all purposes of this Agreement. In the event the
                 parties decide to share in the expenses for applying for,
                 obtaining and maintaining patents claiming such a joint
                 invention or discovery in one or more countries of the
                 Territory, Wyeth-Ayerst shall file and prosecute any such
                 patent applications in such countries and the out-of-pocket
                 expenses incurred by Wyeth-Ayerst in preparing, filing and
                 prosecuting joint patent applications and maintaining patents
                 issuing therefrom shall be shared equally by the parties.

                                      -42-

<PAGE>

     13.2 Prosecution and Maintenance of Patent Rights. Each party shall be
          responsible for prosecuting and maintaining its own patent rights
          throughout the Territory.

     13.3 Cooperation. Each of the parties shall execute or have executed by its
          employees, representatives, agents and contractors such documents as
          may be reasonably necessary to obtain, perfect or maintain any patent
          rights which would be filed pursuant to this Agreement, and to
          cooperate with the other party as far as reasonably necessary with
          respect to furnishing all information and data in its possession to
          obtain patent rights.

     13.4 Patent Infringement. Wyeth-Ayerst shall give immediate notice in
          writing to Neose of any known or presumed infringement in the Field in
          the Territory of any of the Neose Patents and will provide Neose its
          full cooperation in the protection and enforcement of the Neose
          Patents. Any award or recovery from an infringement suit against or a
          settlement with such infringer shall be first applied to the
          reimbursement of legal fees, costs and expenses incurred by the
          parties and the remainder, if any, shall be divided eighty percent
          (80%) to Neose and twenty percent (20%) to Wyeth-Ayerst between the
          parties. In any and all settlements between such alleged infringer of
          Neose Patents and Neose, the prior written consent thereto by
          Wyeth-Ayerst shall be obtained by Neose, such consent not to be
          unreasonably withheld. If Neose fails to either bring suit against or
          to enter into negotiations for a settlement with such alleged
          infringer of a Neose Patent within a reasonable time after written
          notice of the alleged infringement shall have been given to Neose by
          Wyeth-Ayerst, then, to the extent such an infringement occurs in a
          country in the Territory, Wyeth-Ayerst may seek to prevent such
          infringement in such country at its cost in either or both of the
          names of the parties hereto. If Wyeth-Ayerst commences an infringement
          action, Neose shall cooperate fully with Wyeth-Ayerst and any recovery
          obtained by Wyeth-Ayerst as the result of its proceedings by court
          action, settlement or otherwise, shall be the

                                      -43-

<PAGE>

          property of Wyeth-Ayerst after reimbursement of twenty-five percent
          (25%) of the legal fees incurred by Neose in cooperating with
          Wyeth-Ayerst in such infringement action. In any and all settlements
          between such an alleged infringer of Neose Patents and Wyeth-Ayerst,
          the prior written consent thereto by Neose shall be obtained by
          Wyeth-Ayerst, such consent not to be unreasonably withheld.

     13.5 Infringement of Third Party Patent Rights. In the event Wyeth-Ayerst
          should be of the opinion that it can not make, import, use, market
          and/or sell Products in any country of the Territory under Neose
          Patents and Neose Technology under this Agreement without infringing a
          Third Party patent, it shall notify Neose. The parties shall then seek
          an opinion of patent counsel acceptable to both parties. If such
          patent counsel concurs with Wyeth-Ayerst's opinion, they shall, at
          Wyeth-Ayerst's sole option, endeavors to secure a license from the
          Third Party on terms reasonably acceptable to the parties.

          13.5.1 Opinion of Counsel. If, in the opinion of patent counsel
                 selected under Section 13.5, the Third Party patent, if
                 litigated, would be found invalid or not infringed by the
                 manufacture, use or sale of Product, or if the parties
                 otherwise mutually agree to obtain a license to such Third
                 Party patent, the parties shall proceed in accordance with the
                 terms of this Agreement, unless an action for infringement is
                 brought against one or both parties.

          13.5.2 Defense against Claim of Infringement. If either party is sued
                 for infringement of any Third Party patent arising out of the
                 manufacture, use, sale, importation or exportation of a Product
                 in any country of the Territory, the parties shall promptly
                 meet to discuss the course of action to be taken to resolve or
                 defend any such infringement litigation. Each party shall
                 provide the other with such assistance as is reasonably
                 necessary and shall

                                      -44-

<PAGE>

                 cooperation in the defense of any such action. The cost/expense
                 of defending such an action and any damages imposed shall be
                 shared equally by the parties. Payments due Neose pursuant to
                 this Agreement shall be reduced if Wyeth-Ayerst is required to
                 obtain a royalty-bearing license from such Third Party under
                 any patent of said Third Party which would be infringed by the
                 sale of Product by Wyeth-Ayerst and the infringement of such
                 patent cannot be reasonably avoided.

14.  INDEMNIFICATION AND INSURANCE

     14.1 Indemnification by Wyeth-Ayerst. Wyeth-Ayerst shall indemnify, defend
          and hold harmless Neose and its Affiliates, and each of its and their
          respective employees, officers, directors and agents (each an "Neose
          indemnified party") from and against all liability, loss, damage, cost
          and expense (including reasonable attorneys fees) which the Neose
          indemnified party may incur, suffer or be required to pay resulting
          from or arising in connection with (i) the breach by Wyeth-Ayerst of
          any representation or warranty contained in this Agreement; or (ii)
          the promotion, distribution, use, testing, marketing, sale or other
          disposition of the Product by Wyeth-Ayerst, its Affiliates or
          sublicenses. Notwithstanding the foregoing, Wyeth-Ayerst shall have no
          obligation to indemnify, defend or hold harmless any Neose indemnified
          party with respect to claims, demands, costs or judgments which result
          from the willful misconduct or negligent acts or omissions of Neose,
          its Affiliates or any of their respective employees, officers,
          directors or agents.

     14.2 Indemnification by Neose. Neose shall indemnify, defend and hold
          harmless Wyeth-Ayerst and its Affiliates, and each of its and their
          respective employees, officers, directors and agents (each a
          "Wyeth-Ayerst indemnified party") from and against any and all
          liability, loss, damage, cost and expense (including reasonable
          attorneys fees) which the Wyeth-Ayerst

                                      -45-

<PAGE>

          indemnified party may incur, suffer, or be required to pay resulting
          from or arising in connection with the breach by Neose of any
          representation or warranty contained in this Agreement.
          Notwithstanding the foregoing, Neose shall have no obligation under
          this Agreement to indemnify, defend and hold harmless any Wyeth-Ayerst
          indemnified party with respect to claims, demands, costs or judgements
          which result from the willful misconduct or negligent acts or
          omissions of Wyeth-Ayerst, its Affiliates or any of their respective
          employees, officers, directors or agents.

     14.3 Conditions to Indemnification. The obligations of the indemnifying
          party under Sections 14.1 and 14.2 are conditioned upon the delivery
          of written notice to the indemnifying party of any potential liability
          promptly after the indemnified party becomes aware of such liability.
          The indemnifying party shall have the right to assume the defense of
          any part or claim related to the potential liability if it has assumed
          responsibility for the suit or claim in writing. The indemnified party
          shall cooperate with the indemnifying party in the defense of any such
          suit or claim.

     14.4 Settlements. Neither party may settle a suit or claim related to a
          potential liability without the consent of the other party if such
          settlement would impose any monetary obligations on the other party or
          require the other party to submit to an injunction or otherwise limit
          the other party's rights under this Agreement.

     14.5 Insurance. Each party agrees to use its Commercially Reasonable
          Efforts to obtain and maintain, during the term of this Agreement,
          Commercial General Liability Insurance, including Products Liability
          Insurance, with reputable and financially secure insurance carriers to
          cover its indemnification obligations under this Section 14, or in the
          case of Wyeth-Ayerst, self-insurance, with a limit of not less than
          one million dollars ($1,000,000) per occurance and five million
          dollars ($5,000,000) in the aggregate. Each party shall furnish the
          other with a certificate of insurance evidencing liability overage
          upon request.

          may also assign its rights and obligations hereunder in connection
          with a merger or a similar reorganization or sale of all or
          substantially all of its assets. Neose may not otherwise assign any of
          its rights or obligations under this Agreement without the prior
          written consent of Wyeth-Ayerst. Any assignment by Neose under this
          Section 15.1, shall not relieve Neose of its responsibilities for the
          performance of its obligations under this Agreement.

     15.2 Assignment by Wyeth-Ayerst. Wyeth-Ayerst may assign any of its rights
          or obligations under this Agreement in any country to any of its

          for the performance of its obligations under this Agreement.

     15.3 Binding Nature. This Agreement shall be binding upon and inure to the

16.  MISCELLANEOUS

     16.1 Force Majeure. Neither party shall be liable to the other for delay or
          failure in the performance of the obligations on its part contained in
          this Agreement if and to the extent that such failure or delay is due
          to circumstances beyond its control which it could not have avoided by
          the exercise of reasonable diligence. It shall notify the other party
          promptly should such circumstances arise, giving an indication of the
          likely extent and duration thereof, and shall use all commercially
          reasonable efforts to resume performance of its obligations as soon as
          practicable.

     16.2 No Waiver. The failure of either party to require performance by the
          other party of any of that other party's obligations hereunder shall
          in no manner affect the right of such party to enforce the same at a
          later time. No waiver by any party hereto of any condition, or of the
          breach of any provision, term, representation or warranty contained in
          this Agreement, whether by conduct or otherwise, in any one or more
          instances, shall be deemed to be or construed as a further or
          continuing waiver of any such condition or breach, or of any other
          condition or of the breach of any other provision, term,
          representation or warranty hereof.

     16.3 Severability. If a court or other tribunal of competent jurisdiction
          should hold any term or provision of this Agreement to be excessive,
          or invalid, void or unenforceable, the offending term or provision
          shall be deleted, and, if possible, replaced by a term or provision
          which, so far as practicable, achieves the legitimate aims of the
          parties.

     16.4 Relationship Between the Parties. Both parties are independent
          contractors under this Agreement. Nothing herein contained shall be
          deemed to create an employment, agency, joint venture or partnership
          relationship between the parties hereto or any of their agents or
          employees, or any other legal arrangement that would impose liability
          upon one party for the act or failure to act of the other party.
          Neither party shall have any express or implied power to enter into
          any contracts or commitments or to incur any liabilities in the name
          of, or on behalf of, the other party, or to bind the other party in
          any respect whatsoever.
