                                  CONSIDERATION

          In consideration of (i) Lilly's sale of Purchased Assets to NeoSan as
     set forth in this Agreement and (ii) the licenses granted by Lilly to
     NeoSan under the Licensed Technology and Licensed Trademark and Trade
     Dress, as set forth in this Agreement, NeoSan will pay the following
     amounts, as set forth in Sections 2.1 and 2.4:

2.1  NEOSAN'S PAYMENT UPON THE CLOSING DATE. On the Closing Date, NeoSan will
     pay to Lilly the sum of Two Hundred Eleven Million Four Hundred Thousand
     United States Dollars (US$211,400,000) by Federal Reserve electronic wire
     transfer in immediately available funds to an account designated by Lilly.

2.2  NET SALES VOLUME ADJUSTMENT. In the event that, during any consecutive
     twelve (12) calendar month period occurring between (and including) January
     1,2002 and the last day of the calendar month that contains the first year
     anniversary of the Closing Date, the aggregate of the (i) Net Sales of
     Product by Lilly and (ii) the Net Sales of Product by NeoSan or other
     Permitted Sellers equals or exceeds fifty million United States dollars
     ($50,000,000), Lilly will not owe NeoSan any purchase price adjustment
     ("Net Sales Volume Adjustment") pursuant to this Section 2.2; otherwise,
     Lilly will pay to NeoSan a Net Sales Volume Adjustment calculated as set
     forth in SCHEDULE 2.2 attached hereto. For purposes of this Agreement, a
     Net Sale of Product will be deemed to have been made by Lilly, NeoSan or a
     Permitted Seller, as applicable, as of the recorded sale date according to
     GAAP, without regard to whether its customer has actually paid Lilly,
     NeoSan or a Permitted Seller, as applicable. NeoSan will deliver to Lilly
     within fifteen (15) days of the end of each calendar month, a report
     detailing the Net Sales made by NeoSan or another Permitted Seller during
     the previous Calendar Month. Lilly will pay any Net Sales Volume Adjustment
     owed by Lilly pursuant to this Section 2.1 within thirty days after the
     last day of the calendar month that contains the one (1) year anniversary
     of the Closing Date.


                                       12



2.3  PURCHASE PRICE ADJUSTMENT. For any Net Sales of Product by Lilly during any
     calendar month during the period beginning February 1, 2002 and ending the
     day before the Closing Date in excess of (i) four million one hundred
     sixty-seven thousand United States dollars ($4,167,000) for each full
     calendar month during such period, and (ii) the product of four million one
     hundred sixty-seven thousand United States dollars ($4,167,000) multiplied
     by the quotient of the number of days prior to the Closing Date in the
     calendar month that the Closing Date occurs divided by thirty (30) (the
     "Excess Net Sales"), Lilly will pay to NeoSan within thirty (30) days after
     the Closing Date a purchase price adjustment equal to ninety percent (90%)
     of such Excess Net Sales.

2.4  ROYALTY PAYMENT.

          (a) NeoSan will accrue and owe a royalty to Lilly equal to [**]
     percent ([**]%) of Net Sales of a NeoSan New Product in a Calendar Quarter
     in the United States by a Permitted Seller (collectively referred to as the
     "Royalty Payment"), to the extent, and only to the extent, that such Net
     Sales of all NeoSan New Products plus all Net Sales of Products by
     Permitted Sellers in such Calendar Quarter in the United States exceed, in
     the aggregate, the Base Year's Average Quarterly Net Sales. For any partial
     Calendar Quarter in which a NeoSan New Product is sold in the United
     States, for purposes of determining if and to what extent a Royalty Payment
     is due and owing with respect to such NeoSan New Product, the Net Sales of
     all NeoSan New Products in the United States plus all Net Sales of Products
     by Permitted Sellers in the United States in such Calendar Quarter will be
     deemed to be equal to the product of (a) the total of such Net Sales
     multiplied by (b) the quotient of the number of days in such partial
     Calendar Quarter divided by ninety (90) days. For purposes of clarity and
     not in limitation thereof, no royalties will be owed by NeoSan or its
     Affiliates with respect to any Net Sales of Products or any pharmaceutical
     product not coming within the definition of "NeoSan New Product". This
     Section 2.3(a) will be in force with respect to each NeoSan New Product in
     the United States until ten (10) years from the commercial launch of such
     NeoSan New Product in the United States.

          (b) NeoSan will pay to Lilly the Royalty Payment attributable to Net
     Sales of NeoSan New Products made during a Calendar Quarter within sixty
     (60) days of the end of such Calendar Quarter, without regard to whether
     the Permitted Seller's customer has actually paid NeoSan. For purposes of
     this Agreement, a Net Sale of a NeoSan New Product will be deemed to have
     been made as of the recorded sale date according to GAAP, without regard to
     whether its customer has actually paid NeoSan. Within sixty (60) days of
     the end of such Calendar Quarter, NeoSan will provide Lilly with a written
     report detailing the Net


                                       13



     Sales of NeoSan New Products made during the previous Calendar Quarter. All
     payments to Lilly pursuant to this Section 2.2 will be made by NeoSan by
     wire transfer on its due date to an account designated by Lilly no less
     than two business days prior to the date of payment, unless otherwise
     instructed by Lilly.

2.5  AUDITS. NeoSan will keep full and accurate books and records relating to
     the performance required of it of its Royalty Payment obligations under
     this Agreement and its Net Sales of Product. For any period in which NeoSan
     is obligated to pay a Royalty Payment with respect to Net Sales of NeoSan
     New Products, plus two (2) years thereafter, and the period beginning on
     the Closing Date and ending the last day of the calendar month that
     contains the one (1) year anniversary of the Closing Date with respect to
     Net Sales of Product, plus two (2) years thereafter, Lilly will have the
     right, during regular business hours and upon reasonable advance notice, to
     have such books and records of NeoSan audited no more frequently than once
     per Calendar Year so as to verify the accuracy of the information
     previously reported to Lilly. Lilly will, for purposes of such audit,
     utilize only the services of an independent CPA firm selected by Lilly and
     approved by NeoSan, such approval not to be unreasonably withheld.

          Such audit may cover the two (2) Calendar Years preceding the date of
     the request for such audit. Notwithstanding the foregoing, no audit of
     NeoSan pursuant to this Section 2.3 will cover any period of time preceding
     the Closing Date. As a condition for their access to conduct such audit,
     such accountants will agree with NeoSan to keep confidential any in
     formation obtained during such audit and will report to Lilly only their
     conclusions, with a copy or full summary of their oral or written reports
     being provided to NeoSan. The cost of such audit will be borne by Lilly;
     however, in the event such audit reveals that the Royalty Payments or Net
     Sales of Product previously reported to Lilly are less than the properly
     calculated amount of Royalty Payments hereunder or Net Sales of Product, as
     applicable, by five percent (5%) or more, the cost of the audit will be
     borne by NeoSan. NeoSan will include in all sublicenses granted in
     accordance herewith, and any other agreements enabling a Third Person to be
     a Permitted Seller, an audit provision substantially similar to the
     foregoing requiring such Permitted Seller to keep full and accurate books
     and records relating to sales of Products and NeoSan New Products thereby
     and granting Lilly the right to have an independent public accounting firm
     audit the accuracy of the information reported by the sublicensee in
     connection therewith.

2.6  LATE PAYMENTS. Any amounts not paid by either Party when due under this
     Agreement or the Manufacturing Agreement will be subject to interest from
     and including the date payment


                                       14



     is due through and including the date upon which the other Party has
     collected the funds in accordance herewith at a rate equal to the lesser of
     (i) the sum of three percent (3%) plus the prime rate of interest quoted in
     the Money Rates section of the Wall Street Journal, calculated daily on the
     basis of a three hundred sixty-five (365) day year, or (ii) the maximum
     interest rate allowed by law.

                                    ARTICLE 3
                    ASSIGNMENT AND LICENSE OF RIGHTS; CLOSING

3.1  ASSIGNMENT OF PURCHASED ASSETS TO NEOSAN. Subject to the terms and
     conditions set forth herein and in the bill of sale, a form of which is
     attached hereto as Exhibit A ("Lilly Bill of Sale"), on the Closing Date,
     Lilly agrees to assign, sell, convey, transfer and deliver to Neo San and
     to cause its Affiliates to assign, sell, convey, transfer and deliver to
     NeoSan, and NeoSan agrees to buy and accept, Lilly's and its Affiliates'
     entire right, title and interest in and to the Purchased Assets, free and
     clear from all Encumbrances other than Permitted Encumbrances. NeoSan
     hereby acknowledges receipt of copies of certain Books and Records during
     the due diligence process. Lilly will deliver to NeoSan any additional
     Books and Re cords requested by NeoSan on or after the Closing Date within
     a commercially reasonable time after such request. Notwithstanding the
     foregoing, Lilly will be entitled to retain a copy of all or any portion of
     the Books and Records for archive purposes. In the event, following the
     Closing Date, that Lilly or NeoSan discover that any of the Purchased
     Assets were held at the time of Closing by any Affiliate of Lilly and not
     transferred to NeoSan at the Closing, Lilly will cause the transfer thereof
     to NeoSan or NeoSan's designee as soon as is commercially practicable after
     such discovery. Notwithstanding the foregoing, Lilly and its Affiliates'
     assignment, sale, conveyance, transfer and delivery of the Assigned Trade
     Dress is restricted to the use of such trade dress with the Product and any
     NeoSan New Product, and neither this Section 3.1 nor any other part of this
     Agreement will be construed to restrict Lilly, its Affiliates or its
     licensees, assignees or successors from utilizing the Assigned Trade Dress
     in connection with any product or use other than the Product and any NeoSan
     New Product.

3.2  GRANT OF LICENSE TO NEOSAN UNDER LICENSED TECHNOLOGY. Subject to the terms
     and conditions set forth herein, as of the Closing Date, Lilly hereby
     grants to NeoSan, on behalf of Lilly and its Affiliates, and NeoSan
     accepts, under the Licensed Technology, an irrevocable (subject to
     suspension to the extent expressly set forth herein), fully-paid,
     royalty-free, exclusive license, with a right to sublicense or assign such
     license rights in

     any of the foregoing outside the United States solely for importation into,
     and distribution, use, sale, market, co-market, promote and co-promote any
     of the foregoing in, the United States); provided, however, that the
     foregoing license with respect to making or having made any of the
     foregoing outside the United States will be non-exclusive; provided
     further, however, that the foregoing license will not be deemed to be a
     representation, warranty or covenant by Lilly that NeoSan will be able to
     practice the Licensed Technology to make and have made anywhere in the
     world any pharmaceutical product other than the Product or to make or have
     made the Product or any other pharmaceutical product outside of the United
     States. Notwithstanding anything in this Section 3.2 to the contrary, the
     license under the Licensed Technology granted to NeoSan pursuant to this
     Section 3.2 will not preclude Lilly from utilizing the Licensed Technology
     for any Permitted Uses during the term thereof. Further notwithstanding
     anything in this Agreement to the contrary, nothing in this Agreement will
     be deemed to preclude Lilly from granting a license under the Licensed
     Technology to a Third Person solely for purposes of making or having made
     the Product in the United States for distribution, exportation (outside of
     the United States), use, sale, marketing, co-marketing, promoting and
     co-promoting the Product outside of the United States, and Lilly will have
     no liability for granting such license. The licenses granted to NeoSan
     pursuant to this Section 3.2 will be subject to the rights reserved by
     Lilly in the preceding two sentences.

3.3  GRANT OF LICENSE TO LICENSED TRADEMARK AND TRADE DRESS TO NEOSAN.

          (a) Subject to the terms and conditions set forth herein, as of the

     Lilly to inspect the manufacturing process for each Product and NeoSan New
     Product not manufactured by Lilly featuring any of the Licensed Trademark

          (e) Notwithstanding anything in this Section 3.3 to the contrary, the
     licenses under the Licensed Trademark and Trade Dress granted to NeoSan
     pursuant to this Section 3.3 will not preclude Lilly or its Affiliates from

     notwithstanding anything in this Agreement to the contrary, nothing in this
     Agreement will be deemed to preclude Lilly from granting a license under
     the Licensed Trademark and Trade Dress to a Third Person solely for
     purposes of making or having made the Product in the United States for
     distribution, exportation (outside of the United States), use, sale,
     marketing, co-marketing, promoting and co-promoting the Product outside of
     the United States, and Lilly will have no liability hereunder for granting

                                       17

     Trade Dress in the United States.

                                    ARTICLE 4
                     REPRESENTATIONS AND WARRANTIES OF LILLY

4.1  INTELLECTUAL PROPERTY. Lilly represents and warrants that the Product
     Intellectual Property (other than the Assigned Trade Dress), Marketing
     Materials, the Licensed Trademark and Trade Dress (other than the Common
     Law Licensed Trade Dress), and the Licensed Technology (collectively, the
     "Intellectual Property") and the Assigned Trade Dress and Common Law
     Licensed Trade Dress contain all the Patents, Know-How, technology, trade
     secrets, trademarks, and trade dress necessary to conduct the Activities or
     to make, have made, distribute, use, sell, offer to sell, have sold,
     market, co-market, import (into the United States), promote and co-promote
     Products in the United States. However, should Lilly or NeoSan


                                       19



     after the Closing Date discover or learn that Lilly has inadvertently
     omitted any Intellectual Property or any Patents (other than the
     Combination Patents) that contain claims that directly relate to the
     manufacture, use or sale of Product and are used by Lilly to conduct the
     Activities, the Parties will discuss in good faith how to amend this
     Agreement to include (whether by assignment or license) such inadvertently
     omitted intellectual property or Patents, such omission will not be deemed
     to be a breach of this Agreement by Lilly, and Lilly will have no liability
     whatsoever with respect to such omission. Lilly makes no representation or
     warranty that NeoSan will be able to conduct the Activities after the
     Closing Date without acquiring the consents, approvals and permits and
     taking other procedural or substantive steps that are required by
     Applicable Law. For avoidance of doubt, "Intellectual Property does not
     mean or include the Assigned Trade Dress or Common Law Licensed Trade
     Dress. Notwithstanding the foregoing, NeoSan acknowledges and agrees that
     Lilly is not and will not be assigning or licensing to NeoSan the expired
     trademarks listed in SCHEDULE 4.1 attached hereto or any other expired
     trademarks directly and exclusively related to Lilly's propoxyphene
     business (collectively referred to herein as the "Expired Trademarks"), and
     Lilly will have no liability for failing to do so. Lilly acknowledges and
     agrees that NeoSan will have no liability to Lilly in the event that
     NeoSan, following the Closing Date, acts to register or otherwise obtain
     new trademarks substantially similar to, or the same as, the Expired
     Trademarks or uses such new trademarks on its products. The Expired
     Trademarks do not include any of the trademarks listed on Schedule 1.6
     hereto.

4.2  OWNERSHIP OF INTELLECTUAL PROPERTY. Lilly represents and warrants that: (i)
     either Lilly or an Affiliate of Lilly is the owner of the Intellectual
     Property, and (ii) Lilly or its Affiliates can, and have the right to,
     assign or license, as applicable, the Intellectual Property to NeoSan
     without the consent of any Third Person. However, should Lilly or NeoSan
     after the Closing Date discover or learn that the consent of additional
     Third Persons is necessary with respect to the Intellectual Property, if
     the omitted consent does not result in material harm to a material Product
     being sold, or to be sold, by NeoSan in the United States, then such
     inadvertent omission will not be deemed to be a breach of this Agreement by
     Lilly and Lilly will have no liability whatsoever with respect to such
     omission; provided, however, that Lilly diligently pursues such consent
     from such Third Persons.

4.3  CLAIMS RELATED TO USE OF INTELLECTUAL PROPERTY. Lilly represents and
     warrants that there are no pending, or to Lilly's knowledge as of the
     Effective Date, threatened claims against Lilly or its Affiliates asserting
     that any of the Intellectual Property infringes or violates the rights of
     Third Persons or that NeoSan, by practicing under the Intellectual Property
     in conducting


                                       20



     the Activities in the United States as of the Closing Date, would violate
     any of the intellectual property rights of any Third Person.

4.4  NOTICE TO THIRD PERSONS. Lilly represents and warrants that Lilly has not

     the Product Intellectual Property (other than the Assigned Trade Dress) and

     Trade Dress), are valid and enforceable, and, to Lilly's knowledge as of
     the Effective Date, the Licensed Trademark and Trade Dress (other than the
     Common Law Licensed Trade Dress) are free of all Encumbrances except
     Permitted Encumbrances. Notwithstanding the foregoing, NeoSan acknowledges

     prior to the Closing Date. Lilly is assigning, selling, conveying,
     transferring and delivering the Assigned Trade Dress to NeoSan "AS IS", and
     is licensing the Common Law Licensed Trade Dress to NeoSan "AS IS."

4.6  RIGHTS GRANTED TO THIRD PERSONS. Except with respect to the remaining
     deliveries required pursuant to Mylan Agreement, rights granted to its
     Affiliates that, following the Closing Date, will not extend past the
     Permitted Uses, rights granted to its wholesalers and government
     purchasers, Lilly represents and warrants that Lilly and its Affiliates
     have not executed or granted to any Third Person, directly or indirectly,

4.8  NDAS; REGULATORY MATTERS. Lilly represents and warrants that Lilly has
     furnished NeoSan with access to a complete copy of the NDAs, including all
     amendments and supplements thereto and that Lilly has no new drug
     applications or INDs pertaining to propoxyphene-based pharmaceutical
     products, whether issued, pending, abandoned, withdrawn, or in draft form,
     other than those pertaining to the NDAS. Although the NDAs are not "state
     of the art" (which NeoSan hereby acknowledges), Lilly further represents
     and warrants that (i) Lilly has complied in all material respects with all
     Applicable Laws in connection with the preparation and submission to the
     FDA of each of the NDAs, (ii) each of the NDAs has been approved by FDA,

     attached hereto, nothing has come to the attention of Lilly which has led
     Lilly to believe that any of the NDAs are not in good standing with the
     FDA, and (iii) Lilly has filed with the FDA all required notices,
     supplemental applications and annual or other reports, including adverse
     experience reports, with respect to each NDA which are material to the
     ability of Lilly to conduct the Activities. All of the Regulatory Approvals
     are owned exclusively by Lilly or its Affiliates. All Products being sold
     by Lilly in the United States are covered by a Regulatory Approval therein
     that permits such sale in the United States. There is no Action or
     Proceeding by any Governmental or Regulatory Authority pending or, to the
     knowledge of Lilly as of the Effective Date, threatened seeking the
     revocation or suspension of any Regulatory Approval. Except as set forth in
     SCHEDULE 4.8 attached hereto, during the three years prior to the date of
     this Agreement, Lilly and its Affiliates have not received or been subject
     to: (i) any FDA Form 483's directly relating to any Product or directly
     relating to any facility in which such Product is manufactured; (ii) any
     FDA Notices of Adverse Findings directly relating to any Product or
     directly relating to any facility in which such Product is manufactured; or
     (iii) any warning letters or other written correspondence from the FDA or
     any other Governmental or Regulatory Authority directly relating to the
     Product or directly relating to any facility in which such Product is

     Authority asserted that the operations of Seller were not in compliance
     with Applicable Law with respect to any Product or the facilities in which
     any Product is manufactured, tested or stored. Except for the
     representation and warranty contained in this Section 4.8, NeoSan has had
     full and adequate opportunity to review and evaluate the NDAs, NeoSan is
     relying upon its own judgment and experience in connection with the NDAs,
     and Lilly is assigning, selling, conveying, transferring and delivering the
     NDAs to NeoSan "AS IS."

     represents and warrants that, to Lilly's knowledge, there have been no
     recalls, withdrawals, or market replacements of the Product in the United
     States in the past two (2) years and that, to Lilly's knowledge as of the

     replacement for the Product in the United States is pending, likely or
     necessary.

     Affiliates have conducted all the Activities in material compliance with

     submissions required of a former owner of the NDAs pursuant to 21 C.F.R.
     Section 314.72, (c) any filings reasonably requested by NeoSan as may be
     necessary to change the records of ownership in the U.S. Trademark or

     and delivery of this Agreement by Lilly as it relates to the United States
     or the performance of its obligations hereunder as it relates to the United
     States, except for such consents, waivers, approvals, or authorizations the
     failure to obtain which, and such notices the failure to give which, would
     not have a Material Adverse Effect or materially impair or delay Lilly's
     ability to perform its obligations hereunder (the "Required Lilly Third
     Party Consents").

4.15 BROKERAGE. Lilly represents and warrants that no broker, finder or similar

     has not and will not use in any capacity the services of any Person

     accurate, Lilly will immediately notify NeoSan of such fact.

     Lilly's knowledge as of the Effective Date, threatened judicial,
     administrative or arbitral Actions or Proceedings pending as of the date

     individually or together with any other, will have a material adverse
     effect on the ability of Lilly to perform its obligations under this
     Agreement or any agreement or instrument contemplated hereby or otherwise
     have a Material Adverse Effect.

                                 OF THE PARTIES

6.1  IMPLEMENTATION TEAM. The Parties will form a team (the "Implementation
     Team") to oversee the activities contemplated by this Agreement. The
     Implementation Team will be comprised of three (3) members from each Party.
     Each Party will appoint a member representing each of manufacturing,
     marketing/sales and regulatory. Either Party may change its
     representative(s) on the Implementation Team at any time by providing prior
     written notice to the other Party. Unless otherwise agreed to by the

     Calendar Quarter upon no less than thirty (30) days prior written notice
     from one Party to the other to discuss any matters arising out of a Party's
     performance (or non-


                                       27



     performance) of its obligations under this Agreement. The Implementation
     Team will initially be responsible for creating detailed operational plans
     for the transition contemplated by this Agreement; provided, however, that
     the activities contemplated by the foregoing will not take place until

     notice to the other Party, which notice must be accompanied by a written
     agenda of items to be discussed at such special meeting.

     whatever filings, requests or applications are required to be filed with

     rights in Article 3 of this Agreement and to cooperate with one another as
     reasonably necessary to accomplish the foregoing, including (i) the filings
     required of both Parties pursuant to the HSR Act, (ii) the information
     submissions to the FDA provided for pursuant to 21 C.F.R. Section 314.72,

     above, on the Closing Date.

     NDAs, it will have sole responsibility for, among other things, adverse
     event reporting, product quality complaints, label maintenance, other
     regulatory reporting obligations, payment of any and all product
     establishment fees, and medical and technical inquiries. Lilly and NeoSan
     each will keep all records and reports required to be kept by Applicable
     Laws, and each will make its facilities available at reasonable times
     during regular business hours for inspection by representatives of
     governmental agencies. Lilly and NeoSan each will notify the other within
     twenty-four (24) hours of receipt of any notice or any other indication
     whatsoever of any FDA, DEA or other governmental agency inspection,
     investigation or other inquiry, or other notice or communication of any
     type from a governmental agency, involving the manufacturing, selling,
     marketing, promoting, co-promoting and co-marketing of the Product in the
     United States. NeoSan and Lilly will cooperate with each other during any
     such inspection, investigation or other inquiry including allowing upon
     reasonable request a representative of the other to be present during the
     applicable portions of any such inspection, investigation or


                                       28



     other inquiry and providing copies of all relevant documents. NeoSan and
     Lilly will discuss any response to observations or notifications received
     in connection with any such inspection, investigation or other inquiry and
     each will give the other an opportunity to comment upon any proposed
     response before it is made. In the event of disagreement concerning the
     form or content of such response, however, Lilly will be responsible for
     deciding the appropriate form and content of any response with respect to
     any of its cited activities and NeoSan will be responsible for deciding the
     appropriate form and content of any response with respect to any of its
     cited activities.

6.4  EXPENSES. Lilly and NeoSan will each bear their own direct and indirect
     expenses incurred in connection with the negotiation and preparation of
     this Agreement and, except as set forth in this Agreement, the performance
     of the obligations contemplated hereby.

6.5  REASONABLE EFFORTS. Lilly and NeoSan each hereby agrees to use all
     reasonable efforts to take, or cause to be taken, all actions and to do, or
     cause to be done, all things reasonably necessary or proper to make
     effective the transactions contemplated by this Agreement, including such
     actions as may be reasonably necessary to obtain approvals and consents of
     Governmental or Regulatory Authorities and other Persons (including all
     applicable drug listing and NDA notifications to the FDA and DEA
     identifying NeoSan as a distributor of the Product); provided, however,
     that no Party will be required to (i) pay money (other than as expressly
     required pursuant to this Agreement or as implicitly required in order for
     a Party to carry out its obligations hereunder), or (ii) assume any other
     material obligation not otherwise required to be assumed by this Agreement.

6.6  PUBLICITY. The Parties agree that no publicity release or announcement
     concerning the transactions contemplated hereby and under the Manufacturing
     Agreement or, with respect to a NeoSan publicity release or announcement,
     that includes the name of Lilly with respect to such transaction, will be
     issued without the advance written consent of the other, which will not be
     unreasonably withheld, except to the extent such publicity release or
     announcement is after the later of the date of (i) the last to be delivered
     to Lilly of the Loan Facility Highly-Confident Letter and the Bond
     Financing Highly-Confident Letter executed by B of A or (ii) the date that
     both Parties have made the filings required by both Parties pursuant to the
     HSR Act, and is substantially similar to, or whose relevant statements are
     consistent with the statements in, the press release set forth in SCHEDULES
     6.6 attached hereto. Notwithstanding the above, upon the later of the date
     of (i) the last to be delivered to Lilly of the Loan Facility
     Highly-Confident Letter and the Bond Financing Highly-Confident Letter
     executed by B of A or (ii) the date that both Parties have made the filings
     required by both Parties pursuant to


                                       29



     the HSR Act (or such later date as agreed to by the Parties), NeoSan may
     issue the press release set forth at SCHEDULE 6.6. Notwithstanding anything
     in this Section 6.6 and Article 8 to the contrary, each Party may make
     filings or disclosures that are required by Applicable Laws (as determined
     to be so required by outside counsel for the disclosing Party) including
     filings or disclosures required by or to the Securities and Exchange
     Commission (and any other applicable securities exchanges) that discuss the
     subject matter of this Agreement or the Manufacturing Agreement or
     otherwise make reference to the other Party in any way whatsoever;
     provided, however, that such Party provides the other Party with no less
     than three (3) business days to review and comment on such filings, or the
     relevant portions thereof, pertaining to the transactions contemplated
     hereby or by the Manufacturing Agreement, and such Party does not
     unreasonably reject the incorporation of such comments into such filings;
     provided further, however, that such Party will redact any Confidential
     Information of the other Party that, in the opinion of such disclosing
     Party's outside counsel, is not required by Applicable Laws from such
     filings or disclosures; provided further, however, that, such Party will
     use commercially reasonable efforts to obtain confidential treatment by
     such security exchanges with respect thereto.

6.7  COOPERATION. If either Party becomes engaged in or participates in any
     investigation, claim, litigation or other proceeding with any Third Person,
     including the FDA and DEA, relating in any way to the manufacturing,
     selling, marketing, promoting, co-marketing or co-promoting the Product in
     the United States, the other Party will cooperate in all reasonable
     respects with such Party in connection therewith, including using its
     reasonable efforts to make available to the other such employees who may be
     helpful with respect to such investigation, claim, litigation or other
     proceeding, provided that, for purposes of this provision, reasonable
     efforts to make available any employee will be deemed to mean providing a
     Party with reasonable access to any such employee at no cost for a period
     of time not to exceed twenty-four (24) hours (e.g., three (3) eight (8)
     -hour business days), and provided further that neither Party is required
     to disclose any legally privileged documents or information to the other
     Party. Thereafter, any such employee will be made available for such time
     and upon such terms and conditions (including compensation) as the Parties
     may mutually agree.

6.8  CONFLICTING RIGHTS. Neither Party will grant any right to any Third Person
     which would violate the terms of or conflict with the rights granted by
     such Party to the other Party pursuant to this Agreement.


                                       30



6.9  DEEMED BREACH OF COVENANT. Neither Lilly nor NeoSan will be deemed to be in
     breach of this Agreement to the extent such Party's breach is the result of
     any action or inaction on the part of the other Party.

6.10 CUSTOMER ORDERS. Lilly will take such steps as may be reasonably required
     to insure that all customer orders for Product received after the Closing
     Date from customers in the United States are forwarded to NeoSan in writing
     within forty-eight (48) hours after receipt by Lilly. Lilly agrees that any
     customer in the United States ordering or requesting any information with
     respect to the Product after the Closing Date will be informed that NeoSan
     is now supplying the Product.

6.11 EXISTING CONTRACTS. NeoSan will fulfill all contractual pricing offered by
     Lilly on Product only for a period of time sufficient to ensure that Lilly
     is in compliance with its contractual obligation to a Third Person for sale
     of Products in the United States ("Customer Contracts"). Other than
     complying with these preexisting contractual obligations, NeoSan will be
     free in its sole and absolute discretion and without consultation with
     Lilly, to set its prices on Product offered by NeoSan. Lilly and NeoSan
     agree to prorate as of the Closing Date any amounts under the Customer
     Contracts in favor of Lilly with respect to amounts which become due and
     payable after the Closing Date to the extent the benefit is attributable to
     the period prior to the Closing Date, and any amounts under the Customer
     Contracts in favor of NeoSan with respect to amounts which are paid prior
     to the Closing Date to the extent the benefit is attributable to the period
     subsequent to the Closing Date.

6.12 NO ASSIGNMENT OR LICENSES OUTSIDE THE UNITED STATES. Notwithstanding
     anything in this Agreement to the contrary, NeoSan acknowledges and agrees
     that Lilly is not assigning or licensing to NeoSan the rights to make, have
     made, distribute, use, sell, offer to sell, have sold, import, market,
     co-market, promote or co-promote the Product outside the United States,
     except for the non-exclusive rights to make or have made Product outside of
     the United States solely for importation and sale in the United States. The
     rights granted to NeoSan in the United States will in no way limit Lilly's
     rights outside the United States.

6.13 NEOSAN NEW PRODUCTS. During the three-year period beginning on the date of
     receipt by Lilly of written notice from NeoSan that NeoSan has initiated
     development activities related to NeoSan New Products (which NeoSan must do
     within a reasonable time after initiating such development activities),
     NeoSan will, at its sole cost and expense, work diligently and using
     commercially reasonable efforts, consistent with prudent business judgment
     and a balancing of important priorities of NeoSan, based upon the existing
     business situation, to develop at least two NeoSan New Products where in
     NeoSan's good faith opinion, such devel-


                                       31



     opment is technically feasible and commercially justifiable ("Commercially
     Attractive Neo San New Products"), devoting the same degree of attention
     and diligence to such efforts that it devotes to such activities for its
     other products at a comparable stage in development and of comparable
     commercial and development potential, with the objective of developing such
     Commercially Attractive NeoSan New Products for the United States as soon
     as commercially practicable, provided that NeoSan may terminate such
     development activities at any time in the event that it determines in good
     faith that such candidates are unlikely to succeed in becoming Commercially
     Attractive NeoSan New Products.

6.14 MEDICAID AND OTHER REBATES. The Parties will administer and pay all
     rebates, chargebacks and other similar programs as follows:

          (a) Lilly Sales Prior to Closing Date. Lilly will process and be
     responsible for the administration and payment of all federal, state and
     local managed care and other rebate programs, including Medicaid/Medicare
     rebates and Obligations, as well as chargebacks for the Product, in each
     case, related to Product that was sold by Lilly prior to the Closing Date;

          (b) Sales After the Closing Date. NeoSan will process and be
     responsible for the administration and payment of all federal, state and
     local managed care and other rebate programs in the United States,
     including Medicaid/Medicare rebates and Obligations, as well as chargebacks
     for the Product and NeoSan New Products, in each case, related to Product
     and NeoSan New Product that is sold by NeoSan on or after the Closing Date.
     If the Parties are unable to determine whether a Product was sold by Lilly
     prior to the Closing Date or by NeoSan on or after the Closing Date, then
     Lilly will be responsible for any and all such rebates and chargebacks
     received during the sixty (60) day period following the Closing Date, and
     NeoSan will be responsible thereafter.

          (c) Product Returns. NeoSan will be responsible for all returns of
     Product sold on or after the Closing Date in the United States, and Lilly
     will be responsible for returns of Product sold before the Closing Date. If
     the Parties are unable to determine whether a Product was sold by Lilly
     prior to the Closing Date or by NeoSan on or after the Closing Date, in
     each case in the United States, then Lilly will be responsible for all
     returns of such Product received during the sixty (60) day period following
     the Closing Date, and NeoSan will be responsible thereafter with respect to
     the United States.

6.15 RESPONSIBILITY FOR THE NDAS. On the Closing Date, Lilly will transfer the
     NDAs to NeoSan. Following the Closing Date, NeoSan will be responsible for
     and will fulfill all regulatory requirements with respect to the Product
     that are imposed upon NeoSan as the owner of


                                       32



     the NDAs under Applicable Laws. NeoSan will provide Lilly with all
     assistance that is reasonably necessary to effectuate such transfers.
     Notwithstanding the sale and transfer of the NDAs, Lilly will complete the
     assay validations and supplement the NDAs with respect to the change of
     equipment in Lilly's Puerto Rico facility, all as further described in
     SCHEDULE 6.15 attached hereto; provided, however, that if Lilly
     subsequently determines in its reason able discretion that regulatory
     submissions identified in SCHEDULE 6.15 are not needed in order to continue
     manufacturing the Product and the FDA does not require such regulatory
     submissions, Lilly will have no obligation to complete the activities
     described in this sentence or supplement the NDA as described in SCHEDULE
     6.15. Nothing in this Section 6.15 will be construed as requiring Lilly to
     update or upgrade the NDAs to "state of the art" conditions, or requiring
     Lilly to otherwise update the NDA. Upon the Closing Date, NeoSan hereby
     grants to Lilly the right to reference the NDAs for purposes of obtaining
     and/or maintaining marketing authorizations outside of the United States.

6.16 INTELLECTUAL PROPERTY MAINTENANCE. Following the Closing, NeoSan will have
     the sole right to file, prosecute and maintain, at its sole cost and
     expense, (i) the Product Intellectual Property and (ii) any patent
     applications or Patents that cover a NeoSan New Product(s) developed by
     NeoSan or its Affiliates. Lilly will be responsible for and promptly pay
     when due all fees necessary to and will otherwise maintain the Licensed
     Trademark and Trade Dress (other than the Common Law Licensed Trade Dress).

6.17 ENFORCEMENT OF INTELLECTUAL PROPERTY RIGHTS.

          (a) Right to Seek Relief. NeoSan will promptly notify Lilly of any
     infringement or suspected infringement which may come to its notice of any
     Licensed Technology or the Licensed Trademark and Trade Dress, and will
     provide Lilly with any information with respect thereto. Lilly will
     promptly notify NeoSan of any infringement or suspected infringement which
     may come to its notice of any intellectual property rights relating to the
     Product, including the Product Intellectual Property, Licensed Technology,
     or the Licensed Trademark and Trade Dress, and will provide NeoSan with any
     information with respect thereto. In the event of any past, present or
     future infringement by a Third Person of any intellectual property rights
     relating to Copyrights, Assigned Trade Dress (only as it relates to an
     infringement in the United States) or Assigned Trademarks, NeoSan will have
     the sole right (but no obligation) to pursue any and all injunctive relief,
     and any or all compensatory and other remedies and relief (collectively,
     "Remedies") against such Third Person.

          In the event of any infringement by a Third Person of any intellectual
     property rights relating solely to Assigned Trade Dress (as it relates to
     infringement outside the United


                                       33



     States), Licensed Technology or Licensed Trademark and Trade Dress, Lilly
     will have the first right (but not the obligation) to pursue any and all
     Remedies against such Third Person. Should Lilly determine not to pursue
     Remedies with respect to any such intellectual property within thirty (30)
     days after notice from NeoSan requesting Lilly to do so, then NeoSan will
     have the right (but not the obligation) to pursue Remedies against such
     Third Person inside the United States.

          In the event of any infringement by a Third Person in the United
     States of any intellectual property related to the Product or NeoSan New
     Products other than that described in the preceding sentences, NeoSan will
     have the first right (but not the obligation) to pursue any and all
     Remedies against such Third Person. Should NeoSan determine not to pursue
     Remedies with respect to any such intellectual property within thirty (30)
     days after notice from Lilly requesting NeoSan to do so, then Lilly will
     have the right (but not the obligation) to pursue Remedies against such
     Third Person.

          (b) Assistance and Cooperation. In the event that a Party will pursue
     Remedies hereunder, the other Party will use all reasonable efforts to
     assist and cooperate with the Party pursuing such Remedies. Each Party will
     bear its own costs and expenses relating to such pursuit. Any damages or
     other amounts collected will be distributed, first, to the Party that
     pursued Remedies to cover its costs and expenses and, second, to the other
     Party to cover its costs and expenses, if any, relating to the pursuit of
     such Remedies; any remaining amount will be distributed to the Party that
     pursued the Remedies.

6.18 INFRINGEMENT OF THIRD PERSON RIGHTS. In the event that a Third Person
     institutes a patent, trade secret, trademark or other infringement suit, or
     a misappropriation or unfair competition suit in the United States
     (including any suit claiming confusion, deception or dilution of a
     trademark by the Assigned Trademarks, Assigned Trade Dress or Licensed
     Trademark and Trade Dress or interference with any patent claim (pending or
     issued)) against NeoSan or another Permitted Seller during the term of this
     Agreement, alleging that the manufacture, marketing, sale or use of the
     Product infringes one or more Patent, trademark or other intellectual
     property rights held by such Third Person or constitutes misappropriation
     or unfair competition, then NeoSan will have the first right (but not the
     obligation), at its sole expense, to assume direction and control of the
     defense of such claims except to the extent such suit relates to the
     Assigned Trade Dress (as it relates to an infringement outside of the
     United States), the Licensed Technology, or the Licensed Trademark and
     Trade Dress, as to which Lilly will have the first right (but not the
     obligation), at its sole expense, to assume direction and control of the
     defense of such claims. Should NeoSan or Lilly, as applicable, determine


                                       34



     not to pursue the defense of a particular claim within thirty (30) days
     after notice from the other Party requesting NeoSan or Lilly, as
     applicable, to do so, then the other Party will have the right (but not the
     obligation), at its sole expense, to assume direction and control of such
     claims. NeoSan will not have the right to settle or otherwise dispose of
     any such claim with respect to the Assigned Trade Dress (as it relates to
     an infringement outside of the United States), the Licensed Technology or
     the Licensed Trademark and Trade Dress without the consent of Lilly, which
     consent will not be unreasonably withheld.

6.19 SALES TRAINING. Lilly will have no obligation to provide sales training to
     NeoSan.

6.20 NO LIENS. NeoSan will keep the Licensed Technology and Licensed Trademark
     and Trade Dress free from all Encumbrances other than Permitted
     Encumbrances.

6.21 MAINTENANCE OF ACTIVITIES PRIOR TO CLOSING. Except as otherwise set forth
     in Section 6.25, from the date of this Agreement to the Closing Date, Lilly
     will conduct the Activities in the ordinary course of business and not
     enter into any new Contracts including the Product or other Purchased
     Assets (a) giving any third Persons any rights, title or interests in the
     Purchased Assets (other than sales of Products in the ordinary course of
     business), or (b) creating any Encumbrances on the foregoing other than
     Permitted Encumbrances. Lilly agrees that: after the date hereof, without
     NeoSan's prior written consent, which will not be unreasonably withheld, it
     will not take any action with respect to any Material Contract that would
     (x) extend the term of such Material Contract with respect to any Product,
     (y) create or agree to any additional obligations with respect to any
     Product other than price adjustments in the normal course of business, or
     (z) otherwise materially adversely affect NeoSan (other than to terminate
     any such Material Contract in the ordinary course of business).

6.22 UNAVAILABLE CONSENTS.

          (a) Notwithstanding anything to the contrary contained in this
     Agreement, if the sale, assignment, transfer, conveyance or delivery or
     attempted sale, assignment, transfer, conveyance or delivery to NeoSan of
     any asset that would be a Purchased Asset is (i) prohibited by any
     Applicable Law or (ii) would require any authorizations, approvals,
     consents or waivers from a Third Person or Governmental or Regulatory
     Authority and such authorizations, approvals, consents or waivers will not
     have been obtained prior to the Closing Date, then in either case the
     Closing may proceed without the sale, assignment, transfer, conveyance or
     delivery of such affected asset and this Agreement will not constitute a
     sale, assignment, transfer, conveyance or delivery of such asset; provided
     that nothing in this Section 6.22 will be deemed to waive the rights of
     NeoSan not to consummate the transactions con-


                                       35



     templated by this Agreement if the conditions to its obligations set forth
     in Article 7 have not been satisfied or waived.

          (b) In the event that the Closing proceeds without the sale,
     assignment, transfer, conveyance or delivery of any such affected asset set
     forth in Section 6.22(a), then (i) following the Closing, the Parties will
     use their commercially reasonable best efforts, and cooperate with each
     other, to obtain promptly such authorizations, approvals, consents or
     waivers, and (ii) pending such authorization, approval, consent or waiver,
     the Parties will cooperate with each other in any mutually agreeable,
     reasonable and lawful arrangements designed to provide to NeoSan the
     benefits of use of such asset and to Lilly the benefits, including any
     indemnities, that, in each case, it would have obtained had the asset been
     conveyed to NeoSan on the Closing Date; provided, however, that such
     arrangement does not cause either Party to be in breach of any obligation
     owed to a Third Person.

          (c) If authorization, approval, consent or waiver for the sale,
     assignment, transfer, conveyance or delivery of any such asset not sold,
     assigned, transferred, conveyed or delivered on the Closing Date is
     subsequently obtained, Lilly will assign, transfer, convey and deliver such
     asset to NeoSan at no additional cost to NeoSan; provided, however, that
     NeoSan has paid the full purchase price described in Section 2.1, above.

6.23 GUARANTY. NeoSan will cause aaiPharma to execute a Guaranty in the form
     attached hereto as Exhibit B (the "Guaranty").

6.24 FINANCIAL STATEMENTS. Lilly will deliver to NeoSan, at NeoSan's expense,
     audited financial statements with respect to the Products in the United
     States for calendar years 1999, 2000 and 2001 which are compliant with the
     rules and regulations of the United States Securities and Exchange
     Commission and will specifically include Net Sales and gross margin of the
     Products in the United States (the "Financial Statements"). NeoSan will pay
     the cost of the Financial Statements regardless of whether the transactions
     contemplated by this Agreement close.

6.25 FINANCING. NeoSan (or aaiPharma on NeoSan's behalf) will use its
     commercially reasonable best efforts to initiate an offering to raise, on
     commercially reasonable terms (for a comparably-sized company and a
     comparably-sized financing transaction, including interest rate and
     duration), the funds necessary to pay the purchase price described in
     Section 2.1 and, pursuant to such offering, to deliver Offering Memoranda
     to potential investors no later than February 21, 2002 (with respect to the
     Offering Memoranda pertaining to the loan syndication portion of the
     Transaction Financing (the "Loan Facility")) and March 1, 2002 (with
     respect


                                       36



     to the Offering Memoranda pertaining to the bond offering portion of the
     Transaction Financing (the "Bond Offering")). NeoSan (or aaiPharma on
     NeoSan's behalf) will utilize its commercially reasonable best efforts to
     close the financings described in both Offering Memoranda (the "Transaction
     Financing") no later than March 15, 2002. The Transaction Financing will
     take the form of a syndicated loan or bond offering, or any combination
     thereof. Notwithstanding anything in this Agreement to the contrary, Lilly
     will be free to discuss transactions related to the Product with Third
     Persons (but not sign any binding agreements) until NeoSan (or aaiPharma on
     NeoSan's behalf) closes the Transaction Financing for the purpose of having
     a back-up purchaser for the asset should the Transaction Financing fail. A
     prerequisite for NeoSan's distribution of the Offering Memoranda pertaining
     to the Loan Facility to banks and other financial institutions will be (i)
     Lilly's prior written approval of such Offering Memoranda, such approval
     not to be unreasonably withheld, and (ii) Bank of America's ("B of A")
     providing to NeoSan and aaiPharma (and NeoSan will have provided a copy
     thereof to Lilly) a duly executed "highly confident" letter with respect to
     the successful funding of such Loan Facility at the closing of the
     Transaction Financing in a form substantially similar to Exhibit C attached
     hereto (the "Loan Facility Highly-Confident Letter"). A prerequisite for
     NeoSan's distribution of the Offering Memoranda pertaining to the Bond
     Offering to potential investors will be (i) Lilly's prior written approval
     of such Offering Memoranda, such approval not to be unreasonably withheld,
     (ii) B of A's providing to NeoSan and aaiPharma (and NeoSan will have
     provided a copy thereof to Lilly) a duly executed "highly confident" letter
     with respect to the successful funding of the Bond Offering at the closing
     of the Transaction Financing in a form substantially similar to Exhibit D
     attached hereto (the "Bond Financing Highly-Confident Letter"), and (iii)
     that NeoSan (or aaiPharma on NeoSan's behalf) will have been and will
     continue to actively progress with the closing of the Loan Facility in good
     faith. In the event that B of A fails to provide NeoSan (and NeoSan fails
     to provide Lilly with a copy) with the Loan Facility Highly-Confident
     Letter by February 21, 2002, fails to provide the Parties with the Bond
     Financing Highly-Confident Letter by March 1, 2002, or is prohibited from
     issuing the Offering Memorandum pertaining to the Bond Offering as of March
     1, 2002 because of its (or aaiPharma's on NeoSan's behalf) failure to
     actively progress with the closing of the Loan Facility in good faith,
     Lilly will have the right (but not the obligation) to terminate this
     Agreement by written notice to NeoSan at any time prior to B of A's
     delivery to Lilly of such Loan Facility Highly-Confident Letter or such
     Bond Financing Highly-Confident Letter or NeoSan's or aaiPharma's active
     progression with the closing of the Loan Facility in good faith, as the
     case may be. Unless aaiPharma is advised by its outside SEC counsel that,
     in such counsel's opinion, earlier public disclosure or filing with the
     Securities and Exchange Commission or


                                       37



     relevant securities exchange with respect to the transactions covered by
     this Agreement is required by applicable law or regulation, NeoSan will
     not, and will cause aaiPharma not to, make any such public disclosure or
     filing until the Parties have received the Bond Financing Highly-Confident
     Letter. Following the receipt of such Bond Financing Highly-Confident
     Letter or such legal advice of an earlier public disclosure or filing
     obligation, whichever comes first, NeoSan and aaiPharma will be free to
     make such legally required public disclosures or filings, provided that
     such public disclosures or filings will be limited to that which
     aaiPharma's outside SEC counsel advises aaiPharma is legally required, in
     such counsel's opinion, or which is otherwise permitted under Section 6.6
     or Article 8 (other than 8.2(g)) hereof at the relevant time, unless Lilly
     consents to additional disclosure. Notwithstanding the foregoing, NeoSan's
     right to make such public disclosure or filing pursuant to this Section
     6.25 is subject to the conditions set forth in the three provisos at the
     end of Section 6.6 pertaining to disclosures that are required by
     Applicable Laws. NeoSan will cause B of A to have in place Confidentiality
     Agreements no less restrictive than those confidentiality obligations
     customarily used by B of A with Third Persons in other loan syndication
     transactions, with Third Persons to which B of A or its representatives
     discuss the Loan Facility portion of the Transaction Financing.

     contemplated by this Agreement will take place at 10:00 a.m., Indianapolis

     have expired with no further action required of either Party, (ii) the day
     on which the last of the certificates required by Sections 7.1(c) and
     7.2(c) has been delivered by one Party to the other, unless receipt of such
     certificate has been waived in writing by the necessary Party, and (iii)
     the day that the last condition precedents set forth in Sections 7.1 and
     7.2 above has been satisfied or waived by the necessary party, or on such
     other date as may be mutually agreed upon in writing by the Parties (the
     "Closing Date") at the offices of Eli Lilly


                                       40



     and Company, Lilly Corporate Center, Indianapolis, Indiana. Each Party
     hereby agrees to use its commercially reasonable best efforts to deliver
     the certificates described in Sections 7.1(c) and 7.2(c) to the other in a
     timely manner.

          (b) If the closing of the transactions contemplated hereby will not
     have taken place on or before sixty (60) days after the Effective Date, or
     such later date as will be mutually agreed to in writing by Lilly and
     NeoSan, because the conditions described in Sections 7.1 and/or 7.2, above,
     have not been satisfied or waived, then Lilly and NeoSan agree to discuss
     in good faith which substantive terms set forth in this Agreement, the
     Manufacturing Agreement, or any document attached hereto and thereto need
     to be modified as a result of the delay in such closing; provided, however,
     that neither Party will have an obligation to agree to such modification.
     Each Party hereby agrees to use commercially reasonable best efforts to
     consummate the transactions contemplated herein, as modified, on or before
     the sixtieth (60th) day after the Effective Date; provided, however, that
     if the Parties are unable to close the transactions contemplated hereby
     within one-hundred twenty (120) days after the Effective Date, or such
     later date as is mutually agreed to in writing by Lilly and NeoSan, then
     any Party that is not in material default of its obligations under this
     Agreement (including its obligation to deliver the certificates described
     in Sections 7.1(c) in the case of Lilly and 7.2(c) in the case of NeoSan)
     may terminate this Agreement upon written notice to the other and each may
     pursue such other remedies as are available to it at law, in equity or
     under this Agreement. If neither Party is then in default of its
     obligations under this Agreement upon delivery of such termination notice,
     then this Agreement will terminate and neither Party will have any
     Obligation to the other with respect to such termination. In all other
     circumstances, the Parties may each pursue such remedies as are available
     to it at law, in equity or under this Agreement. In addition to, but in no
     way in limitation of the foregoing, Lilly may terminate this Agreement in
     its entirety if NeoSan (or aaiPharma) has not initiated the Loan Facility
     portion of the Transaction Financing by February 21, 2002 (unless such
     termination right has not been exercised by written notice to NeoSan prior
     to the commencement of the offering of the Loan Facility), the Bond
     Offering Portion of the Transaction Financing by March 1, 2002 (unless such
     termination right has not been exercised by written notice to NeoSan prior
     to the commencement of the Bond Offering), and closed the Transaction
     Financing by March 15, 2002 as more fully described in Section 6.25. In the
     event Lilly terminates this Agreement for NeoSan's or aaiPharma's failure
     to close the Transaction Financing by March 15, 2002, NeoSan will have no
     Obligation to Lilly with respect to such termination provided that NeoSan
     and/or aaiPharma used commercially reasonable best efforts to close the
     Transaction Financing by March 15, 2002 and NeoSan is not otherwise in
     breach of this Agreement.

     period following the Effective Date, the Receiving Party will keep
     completely confidential, will not publish or otherwise disclose and will
     not use directly or indirectly for any purpose other than as contemplated
     by this Agreement or the Manufacturing Agreement any such Confidential

     be under any non-disclosure or non-use obligation whatsoever with respect
     to its own Confidential Information.

     order or subpoena and to obtain a protective order requiring that the
     Confidential Information and documents that are the subject of such order
     or subpoena be held in confidence by such court or governmental body or, if
     disclosed, be used only for purposes for which the order or subpoena was
     issued; provided further, however, that if a disclosure order or subpoena
     is not quashed or a protective order is not obtained, the Confidential
     Information disclosed in response to such court or governmental order or
     subpoena will be limited to that information which is legally required to
     be disclosed in such response to such court or governmental order or
     subpoena;

          (b) otherwise as required by law, in the opinion of legal counsel to

     Party in connection with the activities of NeoSan, its Affiliates and
     contractors in the manufacture or development and commercialization of the

     onerous than those set forth in this Section;

          (e) made by the Receiving Party to a United States tax authority;

          (f) made by the Receiving Party to its Representatives; provided,

     (ii) the Receiving Party informs its Representatives receiving Confidential
     Information of its confidential nature; and (iii) the Receiving Party will

     in the opinion of their outside SEC counsel, to be included in legally
     required filings or disclosures with the Securities and Exchange Commission
     or that, in the opinion of their outside counsel or of B of A, is
     commercially necessary in carrying out the Transaction Financing and
     subsequent public exchange offer for the Bond Offering (the "Subsequent
     Exchange Offer")) that are incorporated into, included in, or attached to,
     (I) aaiPharma's filings with the Securities and Exchange Commission
     pertaining to the entering into of this Agreement by the Parties, at such
     times as aaiPharma makes such filings as provided in Sections 6.6 or 6.25,
     subject to the conditions set forth in the three provisos at the end of
     Section 6.6 pertaining to disclosures that are required by Applicable Laws;
     provided, however, that such disclosure of information for which aaiPharma
     receives confidential treatment from the Securities and Exchange Commission
     will only be made to the Securities and Exchange Commission, and provided
     further that NeoSan and aaiPharma may use and disclose, without further
     restriction, Confidential Information included in any such filings or
     disclosures with the Securities and Exchange Commission which is not
     accorded confidential treatment by the Securities and Exchange Commission
     and, as a result, enters the public domain; and (II) the Offering Memoranda
     and other documents pertaining to the Transaction Financing and Subsequent

                                       44



     less restrictive than those confidentiality obligations customarily used by
     B of A with Third Persons in other similar transactions), and (B) at and
     after the time set forth in Section 6.25 (i.e., following the receipt of
     such Bond Financing Highly-Confident Letter or such legal advice of an

     Offering Memoranda and other documents related to the Bond Offering and
     Subsequent Exchange Offer) to potential investors; provided, however, that
     such disclosures will only be made as permitted by and within the scope of
     Section 6.25.

8.3  NOTIFICATION. The Receiving Party will notify the Disclosing Party
     immediately, and cooperate with the Disclosing Party as the Disclosing
     Party may reasonably request, upon the Receiving Party's discovery of any
     loss or compromise of the Disclosing Party's Confidential Information.

8.4  REMEDIES. Each Party agrees that the unauthorized use or disclosure of any
     Confidential Information by the Receiving Party in violation of this
     Agreement or any other agreement forming a part of this transaction will
     cause severe and irreparable damage to the Disclosing Party. In the event
     of any violation of this Article 8, the Receiving Party agrees that the
     Disclosing Party will be authorized and entitled to obtain from any court
     of competent jurisdiction injunctive relief, whether preliminary or
     permanent, without the necessity of proving irreparable harm or monetary
     damages, as well as any other relief permitted by applicable law. The
     Receiving Party agrees to waive any requirement that the Disclosing Party
     post bond as a condition for obtaining any such relief. Except as otherwise
     limited pursuant to Section 11.7, below, the rights provided in the
     immediately preceding sentences will be cumulative and in addition to any
     other rights or remedies that may be available to Disclosing Party. Nothing
     in this Section is intended, or should be construed, to limit a Party's
     right to preliminary and permanent injunctive relief or any other remedy
     for a breach of any other provision of this Agreement.

                                    ARTICLE 9
                                   TERMINATION

9.1  TERMINATION PRIOR TO THE CLOSING. Anything herein to the contrary
     notwithstanding, this Agreement may be terminated as follows prior to the
     Closing Date:

          (a) Termination for Insolvency. Each Party may Immediately terminate
     this Agreement by providing written notice to the other Party if the other
     Party (or, in the case of


                                       45



     NeoSan, an Affiliate of NeoSan) is declared insolvent or bankrupt by a
     court of competent jurisdiction, or a voluntary petition of bankruptcy is
     filed in any court of competent jurisdiction by the other Party (or, in the
     case of Neosan, an Affiliate of NeoSan), or an involuntary petition for
     relief under the United States Bankruptcy Code is filed in a court of
     competent jurisdiction against the other Party (or, in the case of NeoSan,
     an Affiliate of NeoSan) which is not dismissed within thirty (30) days of
     its filing, or the other Party (or, in the case of NeoSan, an Affiliate of
     NeoSan) makes or executes any assignment for the benefit of creditors.

          (b) Termination for Default. Either Party may terminate this entire
     Agreement because of a material breach or material default of this
     Agreement by the other Party as follows: The terminating Party will give
     the other Party prior written notice thereof, specifying in reasonable
     detail the alleged material breach or material default, and if such alleged
     material breach or material default continues unremedied for a period of
     thirty (30) days with respect to monetary breaches or defaults or sixty
     (60) days with respect to non-monetary material breaches or material
     defaults after the date of receipt of the notification or, if the
     non-monetary material breach or material default reasonably cannot be
     corrected or remedied within sixty (60) days, then if (i) the defaulting
     Party has not commenced remedying said material breach or material default
     with said sixty (60) days and be diligently pursuing completion of same,
     and (ii) said material breach or material default has not been corrected or
     remedied within one-hundred twenty (120) days, then such terminating Party
     may immediately terminate this Agreement by again providing written
     notification to the defaulting Party. Except as otherwise limited pursuant
     to Section 11.7 of this Agreement and Section 11.2 of the Manufacturing
     Agreement, this Section 9.1(b) will not be exclusive and will not be in
     lieu of any other remedies available to a Party hereto for any breach or
     default hereunder on the part of the other Party.

9.2  TERMINATION FOLLOWING CLOSING. Following the Closing Date and the payment
     by NeoSan of the $211,400,000 to be paid pursuant to Section 2.1, this
     Agreement may not be terminated by either Party, except that Lilly may
     suspend the licenses granted pursuant to Sections 3.2 and 3.3 utilizing the
     procedures set forth in Section 9.1(b) as a result of any breach by NeoSan
     in the payment of Royalty Payments owed with respect to a NeoSan New
     Product in the United States only to the extent such licenses relate to the
     affected NeoSan New Product therein (but will have no such effect with
     respect to any Products or other NeoSan New Products in the United States
     and will not constitute a material breach of this Agreement or give Lilly
     any rights to terminate any rights of NeoSan hereunder whatsoever other
     than the foregoing express suspension with respect to the relevant NeoSan
     New Product) until and


                                       46



     unless NeoSan pays Lilly any Royalty Payments so owed (including with
     respect to relevant Net Sales of such NeoSan New Product during any period
     of suspension), plus accrued interest as provided in Section 2.5, at which
     time such licenses will be automatically reinstated. Except as otherwise
     set forth in this Section 9.2, the Parties agree that the sole and
     exclusive remedies following the Closing Date will be to seek injunctive
     relief to require compliance by the breaching Party and relief to seek
     damages (subject to Section 11.7) with respect to such breach.

9.3  TERMINATION OF SUBLICENSES. Any sublicenses granted by NeoSan under this
     Agreement with respect to the Licensed Technology or License Trademark and
     Trade Dress will provide for immediate termination (or suspension, as the
     case may be) upon termination (or suspension) of this Agreement or the
     licenses granted in Sections 3.2 and 3.3, as the case may be, to the same,
     and only to the same, extent as such termination (or suspension).

9.4  CONTINUING OBLIGATIONS. Termination of this Agreement for any reason will
     not relieve the Parties of any antecedent breach of the provisions of this
     Agreement or any obligation accruing prior thereto and, subject to Section
     11.7, below, will be without prejudice to the rights and remedies of either
     Party with respect to any antecedent breach of the provisions of this
     Agreement. Without limiting the generality of the foregoing and in addition
     to the foregoing, no termination of this Agreement, whether by lapse of
     time or otherwise, will serve to terminate the rights and obligations under
     Section 9.4 and Articles 8, 11 and 12 hereof, and such obligations will
     survive any such termination.

9.5  NON-EXCLUSIVE REMEDIES. Except as otherwise limited pursuant to Section
     11.7, below, the remedies set forth in this Article 9 or elsewhere in this
     Agreement will be in addition to, and will not be to the exclusion of, any
     other remedies available to the Parties at law, in equity or under this
     Agreement,

     responsible for and to perform and satisfy all responsibilities, duties
     (including compliance with all Applicable Laws), obligations, claims,
     Damages, liabilities, debts, burdens and problems of any nature whatsoever
     (whether known or unknown, asserted or unasserted, absolute or contingent,

     contractor (other than Lilly)), distributing, marketing, promoting, selling
     or using the Product from and after the Closing Date, including all
     recalls, all warranty claims and all product liability claims (without
     regard to the nature of the causes of action alleged or theories of
     recovery asserted) arising in connection with Product sold on or after the
     Closing Date, except for those Obligations with respect to which Lilly is
     providing indemnification pursuant to the provisions of Section 11.1 of
     this Agreement, which Obligations will remain the responsibility of Lilly
     as set forth herein. All of the foregoing are hereinafter collectively

     any Third Person claim alleging breach of any express or implied warranties
     of merchantability or fitness for a particular purpose or asserting strict
     liability; and

          (h) the negligence, gross negligence or willful misconduct of NeoSan,
     its Affiliates or its or its Affiliates' employees, agents or contractors
     (other than Lilly).

11.3 NOTICE AND OPPORTUNITY TO DEFEND. Promptly after receipt by a Party hereto
     of notice of any claim which could give rise to a right to indemnification
     pursuant to Section 11.1 or 11.2, such Party (the "Indemnified Party") will
     give the other Party (the "Indemnifying Party") written notice describing
     the claim in reasonable detail. The failure of an Indemnified Party to give
     notice in the manner provided herein will not relieve the Indemnifying
     Party of its obligations under this Article 11, except to the extent that
     such failure to give notice materially prejudices the Indemnifying Party's
     ability to defend such claim. The Indemnifying Party will have the right,
     at its option, to compromise or defend, at its own expense and by its own
     counsel, any such matter involving the asserted liability of the Party
     seeking such indemnification. The assumption of the defense of a claim by
     the Indemnifying Party will be construed as a binding acknowledgement that
     the Indemnifying Party is liable to indemnify any indemnitee for Damages in
     respect to such claim. If the Indemnifying Party undertakes to compromise
     or defend any such asserted liability, it will promptly (and in any event
     not more than ten (10) business days after receipt of the Indemnified
     Party's original notice) notify the Indemnified Party in writing of its
     intention to do so, and the Indemnified Party agrees to cooperate fully
     with the Indemnifying Party and its counsel in the compromise or defense
     against any such asserted liability, provided that the Indemnified Party is
     not obligated to disclose legally privileged documents or information in
     such cooperation. All reasonable costs and expenses incurred in connection
     with such cooperation will be borne by the Indemnifying Party. If the
     Indemnifying Party elects not to compromise or defend the asserted
     liability, fails to timely notify the Indemnified Party of its election to
     compromise or defend as herein provided, fails to admit its obligation to
     indemnify under this Agreement or the Manufacturing Agreement with respect
     to the claim, or, if in the reasonable opinion of the Indemnified Party,
     the claim could result in the Indemnified Party becoming subject to
     injunctive relief or relief (other than the payment of money damages) that
     could materially adversely affect the ongoing business of the Indemnified
     Party, the Indemnified Party will have the right, at its option, to pay,
     compromise or defend such asserted liability by its own counsel and its
     reasonable costs, expenses, and any payment made therewith will be included
     as part of the indemnification obligation of the Indemnifying Party
     hereunder, where such indemnification obligation exists hereunder.
     Notwithstanding the foregoing, neither the Indemnifying Party nor the
     Indemnified Party may settle or compromise any claim without


                                       50



     consent of the other where such settlement or compromise would impose
     injunctive obligations on the non-settling or non-compromising Party or any
     Damages on the non-settling or non-compromising Party that are not subject
     to indemnification hereunder; provided, however, that consent to settlement
     or compromise will not be unreasonably withheld. In any event, the
     Indemnified Party and the Indemnifying Party may participate, at their own
     expense (or at the Indemnifying Party's expense, in the circumstances
     described above (i.e., if the Indemnifying Party elects not to compromise
     or defend the asserted liability where such indemnification obligation
     exists hereunder)), in the defense of such asserted liability. If the
     Indemnifying Party chooses to defend any claim, the Indemnified Party will
     make available to the Indemnifying Party any non-privileged books, records
     or other documents within its control that are necessary or appropriate for
     such defense; provided, however, any such books, records or other documents
     within the control of the Indemnified Party which are made available to the
     Indemnifying Party hereunder will be held in strict confidence by the
     Indemnifying Party (except to the extent disclosure is reasonably necessary
     for the defense of such claim) and will be disclosed by the Indemnified
     Party to the Indemnifying Party only to the extent that such books, records
     or other documents relate to the claim.

          Notwithstanding anything to the contrary in this Section 11.3, (a) the
     Party conducting the defense of a claim will (1) keep the other Party
     informed on a reasonable and timely basis as to the status of the defense
     of such claim (but only to the extent such other Party is not participating
     jointly in the defense of such claim), and (2) conduct the defense of such
     claim in a prudent manner, and (b) to the extent the Indemnifying Party has
     elected to defend a claim, the Indemnifying Party will not cease to defend
     such claim without the prior written consent of the Indemnified Party
     (which consent will not be unreasonably withheld).

11.4 INDEMNIFICATION PAYMENT OBLIGATION. Notwithstanding anything in this
     Agreement to the contrary, Lilly and NeoSan will have no obligations under
     subsections 11.1 (a) and 11.2(a), respectively, of this Agreement and as
     incorporated by reference in the Manufacturing Agreement to indemnify the
     other Party (or its Affiliates or its or its Affiliates' directors,
     officers and employees) until the cumulative aggregate amount of Damages
     incurred or suffered by such other Party (or its Affiliates or its or its
     Affiliates' directors, officers and employees) which Lilly or NeoSan, as
     the case may be, is otherwise subject to under this Agreement and the
     Manufacturing Agreement exceeds one hundred thousand US Dollars
     (US$100,000) (the "Deductible Amount"), at which time Lilly or NeoSan will
     have the obligation under subsections 11.1 (a) and 11.2(a), respectively,
     of this Agreement and as incorporated by reference in the Manufacturing
     Agreement to indemnify the other Party (or its Af-


                                       51



     filiates or its or its Affiliates' directors, officers and employees) only
     for Damages in excess of the Deductible Amount.

11.5 INDEMNIFICATION PAYMENT ADJUSTMENTS. The amount of any Damages for which
     indemnification is provided under this Article 11 will be reduced by the
     net insurance proceeds received and any other amount recovered, if any, by
     the Indemnified Party with respect to any Damages; provided, however, that
     the foregoing will not under any circumstances reduce the Damages for which
     either Party is obligated to indemnify the other to the extent the
     insurance proceeds received result from a self-insurance program or are
     required to be repaid to the insurer upon recovery of Damages; provided,
     however, that to the extent that an insurance claim would be made under a
     self-insurance program, an Indemnified Party will not be subject to an
     obligation to pursue an insurance claim relating to any Damages for which
     indemnification is sought hereunder, and provided further that the
     Indemnifying Party will reimburse the Indemnified Party for the present
     value of any increased premiums directly attributable to such claims for
     the five year period following such increase, discounted at a 15% discount
     rate. To the extent the preceding sentence is applicable, if any
     Indemnified Party will have received any payment pursuant to this Article
     11 with respect to any Damages and will subsequently have received
     insurance proceeds or other amounts with respect to such Damages, then such
     Indemnified Party will pay to the Indemnifying Party an amount equal to the
     difference (if any) between (a) the sum of the amount of those insurance
     proceeds or other amounts received and the amount of the payment by such
     Indemnifying Party pursuant to this Article 11 with respect to such Damages
     and (b) the amount necessary to fully and completely indemnify and hold
     harmless such Indemnified Party from and against such Damages; provided,
     however, that in no event will such Indemnified Party have any obligation
     pursuant to this sentence to pay to such Indemnifying Party an amount
     greater than the amount of the payment by such Indemnifying Party pursuant
     to this Article 11 with respect to such Damages.

11.6 INDEMNIFICATION PAYMENT. Upon the final determination of liability and the
     amount of the indemnification payment under this Article 11, the
     Indemnifying Party will pay to the Indemnified Party, within ten (10)
     business days after such determination, the amount of any claim for
     indemnification made hereunder.

11.7 LIMITATION OF LIABILITY. EXCEPT FOR (i) THE COSTS OF RECALL ENUMERATED IN
     SECTION 10.3 OF THE MANUFACTURING AGREEMENT TO THE EXTENT SUCH COSTS
     CONSTITUTE INDIRECT, SPECIAL, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE
     DAMAGES, AND (ii) WTTH RESPECT TO DAMAGES INCURRED BY


                                       52



     THIRD PERSONS FOR WHICH A PARTY HERETO OTHERWISE HAS AN INDEMNIFICATION
     OBLIGATION PURSUANT TO SECTION 11.1 OR SECTION 11.2 OF THIS AGREEMENT OR
     SECTION 11.1 OF THE MANUFACTURING AGREEMENT, IN NO EVENT WILL EITHER PARTY
     BE LIABLE FOR INDIRECT, SPECIAL, INCIDENTAL, CONSEQUENTIAL (INCLUDING LOST
     PROFITS) OR PUNITIVE DAMAGES, HOWEVER CAUSED OR UPON ANY THEORY OF
     LIABILITY (INCLUDING A PARTY'S OR ITS AFFILIATES' OWN NEGLIGENCE, GROSS
     NEGLIGENCE OR WILLFUL MISCONDUCT OR THE NEGLIGENCE, GROSS NEGLIGENCE OR
     WILLFUL MISCONDUCT OF A PARTY'S OR A PARTY'S AFFILIATES' EMPLOYEES, AGENTS
     OR CONTRACTORS), ARISING OUT OF THIS AGREEMENT OR THE PERFORMANCE OF, OR
     THE FAILURE TO PERFORM, ANY OBLIGATION(S) SET FORTH HEREIN. NOTWITHSTANDING
     THE FOREGOING, A PARTY'S AGGREGATE LIABILITY TO THE OTHER PARTY UNDER THIS
     AGREEMENT AND THE MANUFACTURING AGREEMENT WITH RESPECT TO ALL INDIRECT,
     SPECIAL, INCIDENTAL, CONSEQUENTIAL (INCLUDING LOST PROFITS) OR PUNITIVE
     DAMAGES INCURRED BY THIRD PARTIES FOR WHICH SUCH PARTY HERETO OTHERWISE HAS
     AN INDEMNIFICATION OBLIGATION PURSUANT TO SECTION 11.1 OR SECTION 11.2 OF
     THIS AGREEMENT OR SECTION 11.1 OF THE MANUFACTURING AGREEMENT WILL BE
     LIMITED TO FIVE MILLION US DOLLARS ($5,000,000).

11.8 INSURANCE. NeoSan will maintain at its own expense, with a reputable
     insurance carrier reasonably acceptable to Lilly, insurance coverage for
     NeoSan, written on a claims made basis, which will name Lilly as an
     additional insured, including errors and omissions insurance and
     comprehensive general liability insurance for claims for damages arising
     from bodily injury (including death) and property damages arising out of
     acts or omissions of NeoSan, which will be specifically endorsed to name
     Lilly as an additional insured. Minimum limits of such insurance (not
     warranted to be necessarily sufficient for the purposes of NeoSan's
     obligation under this Agreement or the Manufacturing Agreement) will be ten
     million US Dollars (US$10,000,000) annual aggregate coverage. Maintenance
     of such insurance coverage will not relieve NeoSan of any responsibility
     under this Agreement or the Manufacturing Agreement for damage in excess of
     insurance limits or otherwise. NeoSan will provide Lilly with a certificate
     from the insurer(s), evidencing such insurance coverage.

11.9 SURVIVAL. Each Indemnified Party's rights under Article 11 will not be
     deemed to have been waived or otherwise affected by such Indemnified
     Party's waiver of the breach of any representation, warranty, agreement or
     covenant contained in or made pursuant this Agreement or the Manufacturing
     Agreement, unless such waiver expressly and in writing


                                       53



     the Manufacturing Agreement, unless such waiver expressly and in writing
     also waives any or all of the Indemnified Party's right under Article 11.

               discretion following the payment of the $211,400,000 pursuant to
               Section 2.1, for assignments wherein NeoSan remains liable for
               the assignee's performance hereunder; and

          (b)  NeoSan may make such assignments following such payment only with
               Lilly's consent, which may not be unreasonably withheld, for
               assignments wherein NeoSan does not remain liable for the
               assignee's performance hereunder.

     Agreement are for convenience only, will not be deemed a part of this
     Agreement and will not affect the meaning or interpretation of this
     Agreement.

12.9 NO THIRD-PERSON RIGHTS. No provision of this Agreement will be deemed or
     construed in any way to result in the creation of any rights or obligation
     in any Person not a Party to this Agreement (except for the rights of a
     Party's Affiliates and its and its Affiliates' directors, officers and
     employees to receive indemnification from the other Party hereunder and
     except for rights of permitted assignees hereunder pursuant to Section
     12.1).

12.10 CONSTRUCTION. This Agreement will be deemed to have been drafted by both
     Lilly and NeoSan and will not be construed against either Party as the
     draftsperson hereof. Unless the context of this Agreement otherwise
     requires: (a) words of any gender include each other gender; (b) words
     using the singular or plural number also include the plural or singular
     number, respectively, (c) the terms "hereof," "herein," "hereby" and
     derivative or similar words refer to this entire Agreement; (d) the terms

                                       56



12.13 SEVERABILITY. If any provision of this Agreement is held to be illegal,
     invalid, or unenforceable under present or future laws effective while this
     Agreement remains in effect, the legality, validity and enforceability of
     the remaining provisions will not be affected thereby.

12.14 FORCE MAJEURE. If either Party is prevented from complying, either totally
     or in part, with any of the terms or provisions set forth herein by reason
     of force majeure, including, by way of example and not of limitation, fire,
     flood, explosion, storm, strike, lockout or other labor dispute, riot, war,
     rebellion, accidents, acts of God, acts of governmental agencies or
     instrumentalities, failure of suppliers or any other similar or dissimilar
     cause, in each case to the extent beyond its control despite its
     commercially reasonable best efforts to avoid, minimize, and resolve such
     cause as promptly as possible, said Party will (a) provide written notice
     of same to the other Party and (b) subject to its following obligations
     with respect to said Party's efforts to remove the disability, its
     obligations that are prevented from compliance by such force majeure are
     suspended, without liability, during such period of force majeure. Said
     notice will be provided within five (5) business days of the occurrence of
     such event and will identify the requirements of this Agreement or such of
     its obligations as may be affected. The Party prevented from performing
     hereunder will use commercially reasonable best efforts to remove such
     disability as promptly as possible and will continue performance whenever
     such causes are removed. The Party so affected will give to the other Party
     a good faith estimate of the continuing effect of the force majeure
     condition and the duration of the affected Party's nonperformance. If the
     Closing Date has not occurred and the period of any previous actual
     nonperformance of Lilly because of Lilly force majeure conditions plus the
     anticipated future period of Lilly nonperformance because of such
     conditions will exceed an aggregate of one hundred twenty (120) days within
     any one year period, NeoSan may terminate this Agreement immediately by
     written notice to Lilly. If the Closing Date has not occurred and the
     period of any previous actual nonperformance of NeoSan because of NeoSan
     force majeure conditions plus the anticipated future period of NeoSan
     nonperformance because of such conditions will exceed an aggregate of one
     hundred twenty (120) days within any one year period, Lilly may terminate
     this Agreement immediately by written notice to NeoSan. When such
     circumstances as those contemplated herein arise, the Parties will discuss
     in good faith, what, if any, modification of the terms set forth herein may
     be required in order to arrive at an equitable solution.


                                       57



     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date first above written.

FOR IMMEDIATE RELEASE

     aaiPharma Acquires Darvon(R) and Darvocet N(R) Pain Franchise from Eli
                                Lilly and Company

WILMINGTON, NORTH CAROLINA (MARCH ___, 2002) - aaiPharma Inc. (Nasdaq: AAII), a
specialty pharmaceutical company, announced today that its NeoSan
Pharmaceuticals business unit purchased the United States rights to the
Darvon(R) and Darvocet N(R) family of pain products from Eli Lilly and Company
(NYSE: LLY).

Under the terms of the agreement, NeoSan will purchase the product line for
$211.4 million plus royalties on future product reformulations. The Darvon(R)
and Darvocet N(R)


                                       77



franchise will become the brand outlet for aaiPharma's pipeline of pain
management products.

The completion of this transaction is awaiting clearance by the Federal Trade
Commission and the Department of Justice of NeoSan Pharmaceutical's recent
filing under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. With this
approval and the closing of the transaction, the Darvon(R) and Darvocet N(R)
family of products would become the latest addition to NeoSan's growing product
portfolio.

"Darvon(R) and Darvocet N(R) represent a tremendous entry vehicle for NeoSan
into the Pain Management Marketplace. Upon closing, we will begin to expand our
sales and marketing operations to drive and grow this brand and our R&D programs
to rapidly develop line extensions to better handle unmet patient needs," said
Dr. Philip Tabbiner, President of NeoSan Pharmaceuticals.

The Darvon(R) and Darvocet N(R) family of pain products are indicated for mild
to moderate pain, a specialty market segment which continues to experience solid
growth in the US.

NeoSan Pharmaceuticals plans to market the Darvon and Darvoet N(R) family with
its growing sales and contracting groups.

"With this acquisition, NeoSan Pharmaceuticals will take another step forward in
its quest to build a robust and exciting pipeline of brands with proven safety
and efficacy records," said Fred Sancilio, Ph.D., Chairman and CEO of aaiPharma.
"As with the other products in our pipeline, we are poised to utilize our proven
scientific expertise to enhance and grow these products, thereby maximizing
their value for our shareholders."
