           shall not affect its construction or interpretation.

 2.   GRANT OF RIGHTS

In consideration of the receipt of the Activation Letter specifying the Compound
and the Route of Administration to be licensed and simultaneous receipt of the
first Milestone payment by Emisphere (both from Lilly), the receipt and adequacy
of which is acknowledged by Emisphere to Lilly by Emisphere's acceptance of the
Activation Letter and Milestone payment, Emisphere grants to Lilly for the term
of this Agreement:

2.1  an exclusive license to use (a) the Emisphere Patents, the Emisphere
     Program Patents and Emisphere's share of the Joint Patents for the Field,
     and (b) the Emisphere Know-How, the Emisphere Program Know-How and
     Emisphere's share of the Joint Know-How for the Field. All proprietary
     rights and rights of ownership with respect to the Emisphere Technology and
     Emisphere Program Technology shall at all times remain solely with
     Emisphere unless otherwise specified in this Agreement. Lilly shall not
     have any rights to use the Emisphere Technology or Emisphere Program
     Technology other than insofar as they relate directly to the Field and are
     expressly granted herein.

2.2  Subject to Clause 6.3, Lilly shall have the right to sublicense the rights
     granted to it by Emisphere pursuant to this Agreement. Insofar as the
     obligations owed by Lilly to Emisphere are concerned, Lilly shall remain
     responsible for all acts and omissions of any sub-licensee as if they were
     by Lilly. Lilly shall forthwith notify Emisphere of any sub-license granted
     by Lilly. In all cases, (i) royalties shall be paid at the rate provided
     for herein (i.e., in accordance with the relevant Option Agreement
     Appendix); and (ii) the applicable royalty rate shall be determined with
     reference to market share or net sales figures (as the case may be)
     determined by cumulating all sales of the Product by Lilly and all of its
     sub-licensees. It shall be Lilly's responsibility in all cases to determine
     the cumulated net sales or market share data and assure that Emisphere is
     paid (whether by Lilly or the sub-licensee) the royalties at the increased
     rate provided for upon reaching the yearly targets, all as set forth in the
     relevant Appendix of the Option Agreement. If Emisphere does not receive
     payment from a sublicensee within [* * *] days of the end of each quarter,
     Emisphere shall immediately notify Lilly's royalty administration personnel
     (contact name

     shall be provided once Product is Launched) that payment has not been
     remitted. If unforeseen circumstances result in a sublicensee not reporting
     to Lilly, the amount of their Net Sales such that Lilly cannot determine
     the cumulative Net Sales or market share data, Lilly shall pay Emisphere
     its royalty due on Lilly Net Sales only and within [* * *] days of the end
     of such calendar quarter, ensure that Emisphere will receive the
     appropriate amount of royalties from either the sublicensee or Lilly.
     Notwithstanding the previous sentence however, Net Sales by sublicensees
     shall not be counted twice in the calculation of royalty payments due to
     Emisphere. In the event of a termination of this Agreement due to a breach
     by Lilly, Emisphere shall have the right but not the obligation to assume
     any such sub-license under the same terms.

In consideration of the obligations assumed hereunder, Lilly grants to
Emisphere, solely for the purposes of carrying out the latter's obligations
hereunder:

2.3  a non-exclusive license to use the Lilly Technology and the Lilly Program
     Technology. All proprietary rights and rights of ownership with respect to
     the Lilly Technology and the Lilly Program Technology shall at all times
     remain solely with Lilly, unless otherwise specified in this Agreement.
     Emisphere shall not have any rights to use the Lilly Technology or the
     Lilly Program Technology other than insofar as expressly granted herein.

2.4  Emisphere shall have no right to sublicense the rights granted to it by
     Lilly pursuant to this Agreement except as expressly authorized by Lilly.
     Insofar as the obligations owed by Emisphere to Lilly are concerned,
     Emisphere shall remain responsible for all acts and omissions of any
     approved sub-licensee as if they were by Emisphere.

3.   IMPROVEMENTS

3.1  If Emisphere shall develop or have developed by an Independent Third Party
     any Improvements during the term of this Agreement (other than pursuant to
     the Research and Development Program which constitute Emisphere Program
     Technology), Emisphere shall, to the extent that it is not prohibited by
     any undertaking given to any Independent Third Party (provided that
     Emisphere shall use its commercially reasonable efforts to exclude or
     minimize the extent of any such limitations or restrictions which prevent
     or limit disclosure to or use by Lilly), communicate to Lilly such
     Improvements and shall provide to Lilly such rights, licenses, information
     and explanations as Lilly may reasonably require to be able effectively to
     utilize the Improvements for the life of this Agreement. Such disclosed
     Improvements shall automatically on disclosure

     to Lilly become part of the Emisphere Know-How or Emisphere Patents, as the
     case may be, and shall be subject to the provisions of this Agreement.

4.   MANUFACTURING

4.1  Lilly will manufacture final Product(s). Emisphere will manufacture at
     least [* * *]% of the Carrier needed for Product sales. Lilly will pay
     Emisphere the latter's [* * *] on all Carrier used for sales of Products
     less than or equal to the sales schedule set forth in the relevant Appendix
     to the Option Agreement. Above the Product sales level specified in the
     relevant Appendix of the Option Agreement, Lilly will pay Emisphere's
     direct manufacturing costs (calculated according to the [* * *]). Lilly
     will be permitted to manufacture up to [* * *]% of the Carrier needed to
     manufacture the Products. If Lilly can find a Carrier source that can offer
     a supply price that is at least [* * *]% lower than Emisphere's supply
     price (including Lilly, with supply price in such case being [* * *], all
     determined in accordance with GAAP principles), Lilly may use such supplier
     for up to [* * *]% of the Carrier needed to manufacture the Product. So
     long as Lilly uses it as a supplier of Carrier, Emisphere will hold at
     minimum [* * *] of Carrier inventory per year to be determined at the
     appropriate time. Emisphere's manufacturing operations will meet any
     required regulatory agency's specifications for registration, as set forth
     in the [* * *].

4.2  Lilly shall be permitted to produce Carrier for its use in clinical trials,
     but only until Emisphere is able to supply the Carrier pursuant to the
     terms of Section 4.1.

4.3  Lilly reserves the right to audit the facility of Emisphere as specified in
     the [* * *], including its processes, records, and other facets of the
     operation as may be necessary to assure that all applicable FDA or similar
     government regulations have been met. Emisphere shall permit duly
     authorized representatives of Lilly to audit all research, development and
     manufacturing areas and operations as they apply to Emisphere projects or
     Carriers for Lilly at reasonable times with a prior appointment. The right
     to audit will also apply to Carrier used in trials to support product
     registration. These audits will be conducted to assure compliance with all
     pertinent acts, regulations, and guidelines promulgated by the FDA and
     other regulatory authorities. Such audits will be permitted during normal
     business hours and will be performed with a minimum of disruption. Lilly
     shall furnish to Emisphere copies of all reports prepared as a result of
     these audits. Lilly agrees to notify Emisphere within [* * *] of any
     concerns that it may have regarding Carrier(s). Lilly will also have the
     right to audit Emisphere's financial manufacturing records in accordance
     with Clause 9.2.

     how Emisphere allocated funds provided by Lilly for such Program, if Lilly
     provided any such funds. Such report shall provide Lilly with the names of
     the Emisphere employees utilized on the Program and the amount of each
     employee's time devoted to the Program. Emisphere shall, further, maintain
     records in reasonable detail and in accordance with GAAP of all monies paid
     by Emisphere for research under the Program and shall provide Lilly, within
     [* * *] of the end of each quarterly period, with a report stating the
     dollar amount of funds supplied by Lilly that were expended on research
     activities during the three month period for which the report is made,
     using Emisphere's standard project accounting procedures, and such
     supporting details as are reasonably required by Lilly. Lilly shall be

     have the costs of the Research and Development Program audited in
     accordance with Clause 9.2.

6.   SUPPLY OF PRODUCT(S)

6.1  Except as otherwise herein provided in this Agreement, Lilly shall produce
     and supply the final commercial Product(s). Any chemical (not including the
     Carriers) or formulation components required to make use of the Emisphere
     Technology shall be procured by Lilly at its own Cost. Lilly shall ensure
     that supplies of the Product(s) are produced as diligently as any of its
     products of similar commercial importance.

6.2  Lilly shall deliver the Product(s) in appropriate packaging as specified in
     the [* * *] so as to permit safe storage and transport.

6.3  In the event that Lilly appoints a third party to manufacture the

     performance of the manufacturer. Lilly shall ensure that said
     manufacturer's facility is an FDA-approved facility and that such facility
     complies with all relevant FDA and other relevant governmental and
     regulatory requirements and that all then-current Good Manufacturing
     Practices are adhered to. In no case will Lilly appoint a third party to
     manufacture the Product(s) if that third party is a competitor with
     Emisphere in the oral protein delivery field or if that third party is
     involved in pending or threatened litigation with Emisphere.

6.4  Pursuant to the procedures set forth in the Manufacturing Responsibilities
     Document, the quality and form of the Product(s) delivered by Lilly
     hereunder shall conform in all material aspects to the Specifications and

7.2  The strategy for the registration and the commercialization of the
     Product(s) shall be determined by Lilly. Upon inquiry, Emisphere shall be
     advised as to Lilly's general commercialization strategy on a semi-annual
     basis. For each country in which the Product is Launched, Lilly shall
     inform Emisphere of the Launch at least [* * *] prior to the expected date
     therefor.


7.3  Lilly shall exert its reasonable efforts to commercialize the Product(s) in
     each country of the Territory where Lilly has Launched Product(s). Such
     efforts shall be consistent with Lilly's efforts on products of similar
     commercial importance.

7.4  Lilly will be solely responsible for ensuring that the manufacture,
     promotion, distribution, marketing and sale of the Product(s) within each
     country of the Territory is in strict accordance with all the legal and
     regulatory requirements of each country of the Territory.

7.5  All advertising, promotional materials and marketing costs needed to
     exploit the Product(s) are to be paid by Lilly. All package inserts, and
     any advertising or promotional materials that substantially reproduce the
     material included in the package inserts, shall, to the extent allowed by
     applicable law or regulation, include: (i) acknowledgment that the Product
     uses Emisphere technology; (ii) Emisphere's trade name (whether or not

8.3  Lilly's obligation to pay royalties shall expire on a country-by-country
     basis upon the conclusion of the term of this Agreement, as set forth in
     Clause 12.1. Emisphere shall file for patent protection on Emisphere
     Technology and Emisphere Program Technology included in the Product in
     those countries listed in Exhibit C to the Option Agreement.

8.4  Payment of royalties shall be made quarterly within [* * *] after the
     expiry of the calendar quarter; provided, that if the information necessary
                                     --------
     to make such payments is not available within such [* * *] period, Lilly
     shall have an additional [* * *] to make such payments. The method of
     payment shall be by wire transfer to an account specified by Emisphere, or
     by such other manner as is mutually acceptable to the Parties. Each payment
     made to Emisphere shall be accompanied by a written report, prepared and
     signed by the appropriate royalty administration personnel of Lilly. The
     report shall clearly show the Net Sales for the calendar quarter for which
     payment is being made on a country-by-country basis. In the event that no
     royalty is due to Emisphere for any quarterly period, Lilly's appropriate
     royalty administration officer shall so report.

8.5  Lilly shall maintain and keep clear, detailed, complete, accurate and
     separate records so:

     8.5.1  as to enable any royalties on Net Sales of the Product(s) which
            shall have accrued hereunder to be determined; and

     8.5.2  that any deductions made in arriving at the Net Sales can be
            determined by Emisphere.

8.6  All payments due hereunder shall be made in United States Dollars. Lilly's
     standard exchange rate methodology will be employed for the translation of
     foreign currency sales into United States Dollars. This methodology shall
     be the one used by Lilly in the translation of its foreign currency
     operating results for external reporting, shall be consistent with general
     accepted accounting principles, and shall be the one approved and reviewed
     by Lilly's independent certified public accountants.

8.7  Subject to the provisions of Clauses 8.8 and 8.10 of this Agreement, Lilly
     shall pay all royalties at full rate.

8.8  If, at any time, legal restrictions in the Territory prevent the prompt
     payment of running royalties or any portion thereof, the Parties shall meet
     to discuss suitable and reasonable alternative methods of reimbursing
     Emisphere the amount of such running royalties. In the event that Lilly is
     prevented from

     making any payment under this Agreement by virtue of the statutes, laws,
     codes or government regulations of the country from which the payment is to
     be made, then such payments may be paid by depositing them in the currency
     in which they accrue to an account set up for Emisphere in a bank
     acceptable to Emisphere in the country the currency of which is involved or
     as otherwise agreed by the Parties.

8.9  Emisphere and Lilly agree to co-operate in all respects necessary to take
     advantage of any double taxation agreements or similar agreements as may,
     from time to time, be available.

8.1  All taxes levied on payment of royalties accruing to Emisphere under this
     Agreement shall be paid by Emisphere. If applicable laws or regulations
     require withholding taxes by Lilly, the taxes will be deducted by Lilly
     from remittable royalties and will be paid by Lilly on account of Emisphere
     to the appropriate government tax authority.

9.   RIGHT OF AUDIT AND INSPECTION

9.1  Within the term of this Agreement and within one year after its
     termination, Emisphere shall not more than [* * *] each year have the right
     at its expense to have Lilly's independent certified public accountants
     inspect and audit Lilly's records for any of the two preceding years for
     the purpose of determining the accuracy of royalty payments. The
     independent certified accountants shall keep confidential any information
     obtained during such inspection and shall report to Emisphere only the
     amounts of Net Sales and royalties due and payable. Any such inspection of
     Lilly's records shall be at the expense of Emisphere, except that if any
     such inspection reveals a deficiency in the amount of the running royalty
     actually paid to Emisphere hereunder in any calendar year of [* * *]% or
     more of the amount of any running royalty actually due to Emisphere
     hereunder, then the expense of such inspection shall be borne solely by
     Lilly. Any amount of deficiency shall be paid promptly to Emisphere. If
     such inspection reveals a surplus in the amount of running royalty actually
     paid to Emisphere by Lilly, Emisphere shall reimburse Lilly the surplus.

9.2  Within the term of this Agreement and within one year after its
     termination, Lilly shall not more than [* * *] each year have the right at
     its expense to have Emisphere's independent certified public accountants
     inspect and audit Emisphere's records and accompanying reports (and all
     associated documentation) for any of the two preceding years for the
     purpose of determining the accuracy of Emisphere's reported, [* * *] and
     Costs with respect to any Research and Development Program. The independent

       public accountants shall keep confidential all materials subject to
       third-party confidentiality agreements and all materials not directly
       relevant to the purpose of their audit. Any such inspection of
       Emisphere's records shall be at the expense of Lilly, except that if any
       such inspection reveals an overpayment in the amount of such Costs paid
       to Emisphere hereunder in any calendar year of [* * *]% or more of the
       amount of such Costs actually due to Emisphere hereunder, then the
       expense of such inspection shall be borne solely by Emisphere instead of
       by Lilly. Any surplus over the Costs properly payable by Lilly to
       Emisphere shall be refunded promptly to Lilly. If such inspection reveals
       a deficit in the amount of the Costs properly payable to Emisphere by
       Lilly, Lilly shall pay the deficit to Emisphere.

9.3    In the event of any unresolved dispute regarding any alleged deficiency
       or overpayment of royalty payments or Cost payments hereunder, the matter
       will be referred to the independent firm of certified public accountants
       of [* * *] for a resolution of such dispute. The decision of said firm of
       certified public accountants shall be binding on the Parties.

10.    PATENTS

10.1   Emisphere shall be obliged to disclose promptly to Lilly inventions made
       by or on behalf of Emisphere in connection with the performance of the
       Research and Development Programs, any patentable inventions and
       discoveries within the Emisphere Know-How that relate to the Field, the
       Emisphere Program Know-How and any patentable Improvements developed by
       or on behalf of Emisphere (other than pursuant to the Research and
       Development Program).

10.2   The Parties shall discuss in good faith all material issues relating to
       filing, prosecution and maintenance of Emisphere Patents (insofar as the
       Emisphere Patents are of relevance to the Field), the Emisphere Program
       Patents, any patentable inventions and discoveries within the Emisphere
       Know-How that relate to the Field, and any patentable Improvements
       developed by or on behalf of Emisphere (other than pursuant to the
       Research and Development Program). Subject to agreement to the contrary
       the following provisions shall apply:

       10.2.1 Emisphere at its expense shall make a good faith effort (a) to
              secure the grant of any patent applications within the Emisphere
              Patents and Emisphere Program Patents; (b) to file and prosecute
              patent applications on patentable inventions and discoveries
              within the Emisphere Know-How and patentable Improvements (or to
              protect such inventions and/or Improvements as trade secrets)
              developed by or on behalf of Emisphere (other than pursuant to the
              Research and

              Development Program); (c) to defend all such applications against
              third party oppositions; and (d) to maintain in force any issued
              letters patent within the Emisphere Patents and Emisphere Program
              Patents (including any letters patent that may issue covering any
              Improvements). Emisphere shall have the sole right in its
              reasonable business discretion to control such filing,
              prosecution, defense and maintenance; provided however, that Lilly
              shall have a reasonable right to be provided with copies of all
              documents relating to such filing, prosecution, defense, and
              maintenance in sufficient time to review such documents and
              comment thereon, if desired by Lilly, prior to filing. Should
              Emisphere decide for commercial or other reasons to abandon in any
              country any patent or patent application pertaining to the
              Emisphere Patents or the Emisphere Program Patents for those
              Carriers that (i) are part of a Product which is either undergoing
              or has gone through a Lilly clinical development program or (ii)
              Emisphere, in good faith, reasonably believes may be utilized as
              part of a Product for clinical development by Lilly, it shall
              first obtain Lilly's written consent, which consent shall not be
              unreasonably withheld.

       10.2.2 In the event that Emisphere informs Lilly that it does not intend
              to file patent applications on patentable inventions and
              discoveries within the Emisphere Know-How or Emisphere Program
              Know-How that relate to those Carriers that have gone through a
              Lilly clinical development program or patentable Improvements
              developed thereon by or on behalf of Emisphere (other than
              pursuant to the Research and Development Program) in one or more
              countries in the Territory or fails to file such an application
              within a reasonable period of time, but in no event less than four
              (4) months after disclosure to Lilly pursuant to Clause 10.1, at
              Emisphere's election, Lilly shall have the right, but not the
              obligation, at Lilly's sole expense to file and prosecute such
              patent application(s) in the name of Lilly and Emisphere, upon
              written request from Lilly, shall execute all documents, forms and
              declarations and do all things as shall be reasonably necessary to
              enable Lilly to exercise such right. In the event that Emisphere
              so elects and Lilly files any such application, such application
              shall [* * *].

10.3   Emisphere shall assist Lilly in good faith regarding all material issues
       that arise from their joint work on the Research and Development Program
       relating to filing, prosecution and maintenance of Lilly Patents (insofar
       as the Lilly Patents are of relevance to the Field), the Lilly Program
       Patents and any patentable inventions and discoveries within the Lilly
       Know-How that relate to the Field. Such assistance will be provided,
       however, only upon Lilly's request. Subject to agreement to the contrary,
       the following provisions shall apply:

       10.3.1 Lilly shall be solely responsible for all facets of filing and
              prosecuting patent applications and maintaining and defending
              patents within the Lilly Patents and the Lilly Program Patents,
              including all expenses pertaining thereto.

       10.3.2 Any assistance from Emisphere requested by Lilly with respect to
              its obligations as set forth in this Clause 10.3 shall be provided
              at Lilly's expense. Emisphere will use its best reasonable efforts
              to provide such assistance in the manner requested by Lilly.

10.4   With respect to any Joint Patents, Emisphere will prepare and file patent
       applications on behalf of both Parties and will diligently prosecute
       same. Prior to the contemplated filing, Emisphere shall submit a
       substantially completed draft of such patent applications to Lilly for
       approval, which approval shall not be unreasonably withheld or delayed.
       In the event of an imminent statutory bar to patenting, Emisphere shall
       have the right to file a patent application, for the invention on which a
       patent would be barred, without first receiving approval from Lilly, in
       order to preserve the patent rights to such invention. Lilly and
       Emisphere shall equally bear the cost of preparing, filing, prosecuting
       and maintaining any patent applications and patents falling within this
       Clause 10.4. Should Emisphere not wish to file, prosecute, maintain or
       issue any patent application falling within this Clause 10.4, or maintain
       a patent issuing from any such patent applications, in any particular
       country, Emisphere will grant Lilly any necessary authority to file,
       prosecute, maintain or issue such patent application, or maintain such a
       patent, in the name of Lilly. However, in such case, such patent
       application or patent for such country shall be considered to be a Lilly
       Program Patent. Likewise, should Lilly not wish to file, prosecute,
       maintain or issue any patent application falling with this Clause 10.4,
       or maintain a patent issuing from such patent applications, in any
       particular country, Lilly will grant Emisphere any necessary authority to
       file, prosecute, issue and maintain such patent application, or maintain
       such a patent, in the name of Emisphere. However, in such case, such
       patent application or patent for such country shall be considered to be
       an Emisphere Program Patent.

10.5   Emisphere and Lilly shall promptly inform the other in writing of any
       alleged infringement of any patents within the Emisphere Patents, the
       Emisphere Program Patents or the Joint Patents or of any alleged
       misappropriation of trade secrets within the Emisphere Know-How, the
       Emisphere Program Know-How or the Joint Know-How, as such infringement or
       misappropriation relates to the Field, by a third party of which it
       becomes aware and provide the other with any available evidence of such
       infringement or misappropriation.

       10.5.1 (a) Emisphere shall have the primary right, but not the
              obligation, to institute, prosecute and control any action or
              proceeding with respect to any infringement of any of the
              Emisphere Technology or the Emisphere Program Technology by
              counsel of its own choice. Lilly shall cooperate with Emisphere at
              Emisphere's request in the prosecution of such action or
              proceeding. If Emisphere reasonably determines that Lilly is an
              indispensable Party to the action, Lilly hereby consents to be
              joined. In such event, Lilly shall have the right to be
              represented in that action by counsel of its own choice and at
              Lilly's expense.

              (b) If Emisphere fails to bring an action or proceeding within a
              period of [* * *] after receiving written notice from Lilly or
              otherwise having knowledge of infringement of the Emisphere
              Technology or the Emisphere Program Technology in the Field, Lilly
              shall have the right to bring and control any such action by
              counsel of its own choice and expense. If Lilly reasonably
              determines that Emisphere is an indispensable Party to the action,
              Emisphere hereby consents to be joined. In such event, Emisphere
              shall have the right to be represented in that action by counsel
              of its own choice and at Emisphere expense.

              (c) No settlement, consent judgment or other voluntary final
              disposition of a suit under this Clause 10.5.1 may be entered into
              without the joint consent of Lilly and Emisphere (which consent
              shall not be withheld unreasonably or delayed by either Party).

              (d) If Emisphere brings an action hereunder, any damages or other
              monetary awards recovered by Emisphere attributable to sales of
              Product shall be applied first to defray the costs and expenses
              incurred in the action. If any balance remains, Emisphere shall
              pay Lilly [* * *]% of such balance.

              (e) If Emisphere fails to bring an action hereunder and Lilly
              brings action, any damages or other monetary awards recovered by
              Lilly attributable to sales of Product shall be applied first to
              defray the costs and expenses incurred in the action. If any
              balance remains, Lilly shall pay Emisphere [* * *]% of such
              balance.

              (f) In the alternative, the Parties may agree to institute such
              proceedings in their joint names and shall reach agreement as to
              the proportion in which they will share the proceeds of any such
              proceedings, and the expense of any costs not recovered.

              (g) If the infringement of the Emisphere Patents or the Emisphere
              Program Patents affects the Field as well as other products being
              developed or commercialized by Emisphere or its commercial
              partners, the Parties shall agree as to the manner in which the
              proceedings should be instituted and shall reach agreement as to
              the proportion in which they will share the proceeds of any such
              proceedings, and the expense of any costs not recovered.

       10.5.2 During the term of this Agreement, Lilly shall have the first
              right but not the obligation to bring suit or otherwise take
              action against any alleged infringement of the Lilly Program
              Patents or alleged misappropriation of the Lilly Program Know-How.
              In the event that Lilly takes such action, Lilly shall do so
              solely at its own cost and expense and all damages and monetary
              award recovered in or with respect to such action shall be the
              property of Lilly. At Lilly's reasonable request, Emisphere will
              co-operate with any such action at Lilly's sole cost and expense.

       10.5.3 During the term of this Agreement, both Parties shall have the
              right but not the obligation to bring suit or otherwise take
              action against any alleged infringement of the Joint Patents or
              alleged misappropriation of the Joint Know-How. Both Parties shall
              be obligated to inform the other of any infringement or
              misappropriation of which they become aware. The Parties shall
              jointly determine in good faith how to manage any action with
              respect to any such infringement or misappropriation. In the
              alternative, or if one party desires to take such an action and
              the other does not, the Party that takes such action shall do so
              solely at its own cost and expense and all damages and monetary
              award recovered in or with respect to such action shall be the
              property of that Party. At such Party's reasonable request, the
              other Party will co-operate with any such action at the requesting
              Party's sole cost and expense.

10.6   Emisphere may defend against any Third Party claim that is related to the
       Emisphere Patents, Emisphere Program Patents, Emisphere Know-How or
       Emisphere Program Know-How. Lilly shall cooperate with Emisphere as may
       be reasonably requested by Emisphere in such defense and shall have the
       right to be represented by counsel of its own choice at Lilly's expense
       provided that Emisphere shall (i) keep Lilly fully informed with regard
       to the defense of such Third Party claim and (ii) obtain Lilly's prior
       written approval before entering into any settlement in connection with
       such Third Party claims, such approval not to be unreasonably withheld or
       delayed.

       If within [* * *] of receiving notice of any Third Party claim related to
       the Field, Emisphere fails to defend against such Third Party claim,
       Lilly may, at its own cost, defend against such Third Party claim;
       provided that Lilly shall (i) keep Emisphere fully informed with regard
       to the defense of such Third Party claim, and (ii) obtain Emisphere's
       prior written approval before entering into any settlement in connection
       with such Third Party claim, such approval not be unreasonably withheld
       or delayed. Emisphere shall cooperate with Lilly as may reasonably be
       requested by Lilly in such defense and shall have the right to be
       represented by counsel of its own choice at Emisphere's expense. If
       royalties or lump sum payments are due to the Third Party by reason of a
       court order or litigation settlement, such payment shall be solely the
       responsibility of Lilly, provided that [* * *]% of such Third Party
       royalties or lump sum payments shall be offset against royalties payable
       to Emisphere under this Agreement, not to exceed the royalties due
       Emisphere, as also set forth in Clause 13.1.

10.7   Except as provided in Clauses 10.6 and 13.1, Emisphere shall have no
       liability to Lilly whatsoever or howsoever arising for any losses
       incurred by Lilly as a result of having to cease selling Product(s) or
       having to defer the Launch of Product(s) as a result of any infringement
       proceedings.

11.    CONFIDENTIAL INFORMATION

11.1   The Parties acknowledge that it may be necessary, from time to time, to
       disclose to each other confidential and proprietary information,
       including without limitation, inventions, works of authorship, trade
       secrets, specifications, designs, data, know-how and other information,
       relating to the Field, the Compounds, the Carriers, the Products,
       processes, and services of the disclosing Party or regarding the
       Emisphere Technology or Emisphere Program Technology or the Lilly
       Technology or the Lilly Program Technology. The foregoing shall be
       referred to collectively as "Confidential Information". Any Confidential
       Information revealed by a Party to another Party shall be used by the
       receiving Party exclusively for the purposes of fulfilling the receiving
       Party's obligations under this Agreement.

11.2   Each Party agrees to disclose Confidential Information of another Party
       only to those employees, representatives and agents requiring knowledge
       thereof in connection with their duties directly related to the
       fulfilling of the Party's obligations under this Agreement. Each Party
       agrees that it will exercise the same degree of care, but in no event
       less than a reasonable degree, and protection to preserve the proprietary
       and confidential nature of the Confidential Information disclosed by the
       other Party, as the receiving Party would exercise to preserve its own
       proprietary and confidential information.

       Each Party agrees that it will, upon request of the other Party, return
       all documents and any copies thereof containing Confidential Information
       belonging to or disclosed by, such Party if such documents are not
       required to perform its obligations hereunder, and further provided that
       the returning party may keep one copy of all such documents in its legal
       archive for recording purposes.

11.3   With respect to all Confidential Information furnished by one Party to
       the other pursuant to this Agreement, either in writing or orally, the
       Party receiving such Confidential Information shall maintain the
       confidential and proprietary status of such Confidential Information,
       keep such Confidential Information and each part thereof within its
       possession or under its control, use all its reasonable efforts to
       prevent the disclosure of any Confidential Information to any other
       person, and use all its reasonable efforts to ensure that such
       Confidential Information is used only for those purposes specifically
       authorized by this Agreement. These mutual obligations of confidentiality
       shall apply until ten (10) years after termination or expiration of this
       Agreement. Confidential Information, further, shall not be deemed to
       include any information to the extent that such information is:

       (a) independently developed by the recipient as documented by prior
       written records outside the scope and not in violation of this Agreement;

       (b) in the public domain at the time of its receipt or thereafter becomes
       part of the public domain through no fault of the recipient;

       (c) received without an obligation of confidentiality from a third party
       having the right to disclose such information;

       (d) released from the restrictions of this Clause 11 by the express
       written consent of the disclosing Party;

       (e) required by law, statute, rule or court order to be disclosed (the
       disclosing Party shall, however, use reasonable efforts to obtain
       confidential treatment of any such disclosure, consult with the other
       Party and permit the other Party to participate in seeking an appropriate
       protective order).

       Notwithstanding the provisions of this Clause 11, Emisphere and Lilly
       may, to the extent necessary, disclose and use Confidential Information
       only for the purpose of carrying out their duties and obligations under
       this Agreement (i) to any Affiliate, sublicensee or subcontractor of
       either Emisphere or Lilly hereunder (if such sublicensee or subcontractor
       is subject to provisions substantially similar to those set forth in this
       Clause 11); (ii) to secure patent

       or market any Product subject to confidential treatment if possible.

11.4   The Parties agree that the obligations of this Clause 11 are necessary
       and reasonable in order to protect the Parties' respective businesses,
       and each Party expressly agrees that monetary damages would be inadequate
       to compensate a Party for any breach by the other Party of its covenants
       and agreements set forth herein. Accordingly, the Parties agree and
       acknowledge that any such violation or threatened violation will cause
       irreparable injury to a Party and that, in addition to any other remedies
       that may be available, in law and equity or otherwise, any Party shall be
       entitled to obtain injunctive relief against the threatened breach of the
       provisions of this Clause 11, or a continuation of any such breach by the
       other Party, specific performance and other equitable relief to redress
       such breach together with its damages and reasonable counsel fees and
       expenses to enforce its rights hereunder, without the necessity of
       proving actual or express damages.

12.    TERM OF AGREEMENT

12.1   Subject to the provisions for earlier termination set out in Clauses
       12.2, 12.3, and 12.6 and the provisions regarding the payment of
       royalties in Clause 8, the term of this Agreement shall be a period
       commencing as of the Effective Date and expiring on a country by country
       basis on the last to occur of:

       12.1.1 nine (9) years from the date of Launch of the Product(s) in the
              country concerned; or

       12.1.2 upon the expiration of the last to expire patent included in the
              Emisphere Patents, the Emisphere Program Patents and/or the Joint
              Patents to the extent that any such patents cover Products(s).

12.2   In addition to the rights of early or premature termination provided for
       elsewhere in this Agreement, in the event that any of the terms or
       provisions hereof are incurably breached by either Party, the non-
       breaching Party may immediately terminate this Agreement by written
       notice. Subject to the other provisions of this Agreement, in the event
       of any other breach, the non-breaching Party may terminate this Agreement
       by giving written notice to the breaching Party that this Agreement will
       terminate on the sixtieth (60th) day from notice unless cure is sooner
       effected. If the breaching Party has proposed a course of action to
       rectify the breach and is acting in good faith to rectify same but has
       not cured the breach by the sixtieth (60th) day, the

       said period shall be extended by such period as is reasonably necessary
       to enable the breach to be cured. If termination of this Agreement
       pursuant to this Clause 12.2 is caused by a breach of this Agreement by
       Lilly, Lilly shall lose all rights pursuant to Clauses 2 and 3 above. If
       Emisphere breaches this Agreement then restitution to Lilly appropriate
       for the degree of the breach shall be made, and Lilly shall continue
       payments pursuant to a mutually acceptable escrow agreement until the
       matter is resolved.

12.3   As used in this Clause 12, the term "Event of Bankruptcy" relating to
       either Party shall mean:

       (a)    the appointment of a liquidator, receiver, administrator,
              examiner, trustee or similar officer over either Party or over all
              or a substantial part of its assets under the law of any
              applicable jurisdiction, including without limit, the United
              States of America; or

       (b)    an application or petition for bankruptcy, corporate re-
              organization, composition, administration, examination,
              arrangement or any other procedure similar to any of the foregoing
              under the law of any applicable jurisdiction, including without
              limitation, the United States of America, is filed, and is not
              discharged within thirty (30) days, or if either Party applies for
              or consents to the appointment of a receiver, administrator,
              examiner or similar officer over it or over all or a material part
              of its assets, rights or revenues or the assets and/or the
              business of either Party are for any reason seized, confiscated or
              condemned.

       12.3.1 If at any time during the term of this Agreement, an "Event of
              Bankruptcy" (as defined above) relating to Emisphere occurs, Lilly
              shall have, in addition to all other legal and equitable rights
              and remedies available hereunder, the option to terminate this
              Agreement upon thirty (30) days' written notice, given within
              sixty (60) days following the date that Lilly becomes aware of the
              Event of Bankruptcy. Upon such termination by Lilly, Lilly shall
              be entitled to solely continue the activities conducted or to be
              conducted pursuant to this Agreement but for the Event of
              Bankruptcy.

       12.3.2 If at any time during the term of this Agreement, an "Event of
              Bankruptcy" (as defined above) relating to Lilly occurs, other
              than in circumstances where the Event of Bankruptcy arises
              directly or indirectly as a result of a dispute with Emisphere and
              it is unlikely that the Event of Bankruptcy would have arisen if
              Lilly and Emisphere had been in agreement, rather than in dispute,
              Emisphere shall have, in

              following the date that Emisphere becomes aware of the Event of
              Bankruptcy.

12.4   Upon exercise of those rights of termination as specified in Clause 12.1
       to Clause 12.3 inclusive or elsewhere within the Agreement, this
       Agreement shall, subject to the other provisions of the Agreement,
       automatically terminate forthwith and be of no further legal force or
       effect.

12.5   Upon expiration or termination of the Agreement:

       12.5.1 any sums that were due from Lilly to Emisphere on Net Sales in the
              Territory or in such particular country or countries in the
              Territory, as the case may be, prior to the expiration or
              termination of this agreement as set forth herein shall be paid in

              force and effect;

       12.5.3 all responsibilities and warranties shall insofar as are
              appropriate remain in full force and effect;

       12.5.4 the rights of inspection and audit set out in Clause 9 shall
              continue in force for a period of one year;

       12.5.5 except as expressly provided for under Clauses 12.2 and 12.5.7 all
              rights and licenses granted in and pursuant to this Agreement
              shall cease for the Territory or for such particular country or
              countries in the Territory, as the case may be. Following such
              expiration or termination, Lilly may not thereafter, except as
              expressly provided for in Clauses 12.2 and 12.5.7, use in the

              in the Territory or any particular country in the Territory, Lilly

              country or countries in the Territory, as the case may be, if any,

              country or countries in the Territory, as the case may be, or, if

              thereof shall be subject to the royalty provisions of Clause 8 and

              Product(s) shall be disposed of by mutual agreement of the Parties
              in accordance with regulatory requirements.

       12.5.7 upon the conclusion of the term of this Agreement in any
              particular country, Lilly shall have a fully paid-up, exclusive
              license to make or use the Emisphere Know-How and Emisphere

       Lilly) research and development commitments by Emisphere in place at the
       time of such notice of termination to the extent that Emisphere cannot
       terminate the same without penalty.

       If Lilly terminates this Agreement without cause (e.g., for reasons other
       than safety of the Carriers, clinical results of the Product, or the
       Emisphere Technology efficiency), the Parties will issue a joint press
       release which states that the termination was not due to the Emisphere
       Technology, and that Lilly will continue to evaluate the Emisphere
       Technology with respect to other Lilly therapeutic Compounds.

13.    WARRANTIES/INDEMNITIES

13.1   Emisphere represents and warrants that it has the sole, exclusive and
       unencumbered right to grant the licenses and rights herein granted to
       Lilly, and that it has not granted any option, license, right or interest
       in or to the Emisphere Technology, the Emisphere Program Technology, the
       Carriers or the Product(s) to any third party which would conflict with
       the rights granted by this Agreement.

       In the case where the Emisphere Technology or the Emisphere Program
       Technology is covered by a patent or patents (or other intellectual
       property rights) held by an Independent Third Party, and both Emisphere
       and Lilly agree that a license is required under any such patent (or
       other intellectual property right) for the Parties to utilize the
       Emisphere Technology or the Emisphere Program Technology, Emisphere shall
       obtain such license and shall not pass on to Lilly, in any manner, any of
       the costs associated with obtaining such a license, including royalties
       to the Independent Third Party. In no case, however, shall Emisphere be
       required to obtain such a license if the costs of so doing would exceed
       the royalty payments by Lilly provided for hereunder. However, Lilly
       shall be permitted to obtain such a license and deduct from royalties
       otherwise due to Emisphere the costs of obtaining the license, up to a
       limit of all royalty payments due to Emisphere hereunder. In any such
       case, Lilly, in its negotiations with the Independent Third Party with
       respect to the amount of compensation for such a license, shall act in
       good faith vis a vis Emisphere.

13.2   Lilly represents and warrants that it has the sole, exclusive and
       unencumbered right to grant the licenses and rights herein granted to
       Emisphere and that it has not granted any option, license, right or
       interest in or to the Lilly Technology or the Lilly Program Technology to
       any third party which would conflict with the rights granted by this
       Agreement.

       In the case where the Lilly Technology or the Lilly Program Technology is
       covered by a patent or patents (or other intellectual property rights)
       held by an Independent Third Party, and, as a result thereof, either (i)
       Lilly is prohibited from continuing the development or sale of a Product
       or (ii) Lilly ceases development or sale of a Product because the costs
       associated with obtaining the rights to proceed with development or sale
       of the Product make such continued development or sale uneconomic in
       Lilly's sole judgment, then the licenses granted hereunder by Emisphere
       shall no longer be exclusive to Lilly, and Emisphere shall, in its sole
       discretion, have the right to enter into a license agreement with such
       Independent Third Party for use of the Emisphere Technology or Emisphere
       Program Technology in the development or sale of the Product. The
       foregoing shall not be interpreted so as to imply any license of the
       Lilly Technology or the Lilly Program Technology to Emisphere or to the
       Independent Third Party, nor shall this clause be deemed an impediment to
       any agreement among Emisphere, Lilly and the Independent Third Party to
       develop or sell the Product.

13.3   Emisphere represents and warrants that to the best of its knowledge, the
       true inventors of the subject matter claimed are named in the Emisphere
       Patents

       interests therein to Emisphere.

       material to the examination of the Emisphere Patents that was not

       that the execution of this Agreement by them and the full performance and

       that as of the Effective Date of executing this Agreement, to the best of
       their knowledge no patents, trade secrets or any other proprietary rights
       of any third party would be infringed by the manufacture, use or sale of
       the Product(s).

13.7   Lilly represents and warrants that with respect to all regulatory filings
       to obtain NDA approvals, to the best of Lilly's knowledge, the data and
       information in Lilly's submission(s) are and shall be free from fraud or
       material falsity, that the NDA approvals have not been and will not be
       obtained either through bribery or the payment of illegal gratuities,
       that the data and information in Lilly's submissions are and shall be
       accurate and reliable for purposes of supporting approval of the
       submissions, and that the NDA approvals are and shall be obtained without
       illegal or unethical behavior of any kind.

13.8   Lilly represents and warrants that the Product(s) sold by Lilly under
       this Agreement shall conform to the Specifications and be in accordance
       with all regulations and requirements of the FDA including the then
       current Good Manufacturing Practice regulations which apply to the
       manufacture and supply of the Product(s). Lilly represents and warrants
       that the Product(s) sold by it shall not be adulterated or mis-branded as
       defined by the US Federal Food, Drug and Cosmetic Act, and shall not be a
       product which would violate any section of such Act if introduced in
       interstate commerce. EXCEPT AS EXPRESSLY STATED IN THIS CLAUSE 13.8, ALL
       OTHER WARRANTIES, CONDITIONS AND REPRESENTATIONS, EXPRESS OR IMPLIED,

       or obligation by Emisphere hereunder, or (b) any act or omission on the

       out of or in connection with any (a) breach of any representation,
       covenant, warranty or obligation by Lilly hereunder, or (b) any act or
       omission on the part of Lilly or any of its agents or employees in the

       arising out of any faults of the Product(s) resulting from the transport,

       Product(s) by Lilly, to the extent that it was caused by the negligence
       or wrongful acts or omissions on the part of Lilly.

13.15  Emisphere shall assume the sole and entire responsibility and shall
       indemnify and hold harmless Lilly from any and all claims, liabilities,

       13.16.3  cooperate in the investigation and defense of such claim or
                proceeding;

       13.16.4  not compromise or otherwise settle any such claim or proceeding

                consent shall not be unreasonably withheld, conditioned or

       13.16.5  take all reasonable steps to mitigate any loss or liability in
                respect of any such claim or proceeding.

13.17  NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, EMISPHERE AND
       LILLY SHALL NOT BE LIABLE TO THE OTHER BY REASON OF ANY REPRESENTATION OR
       WARRANTY, CONDITION OR OTHER TERM OR ANY DUTY OF COMMON LAW, OR UNDER THE
       EXPRESS TERMS OF THIS AGREEMENT, FOR ANY CONSEQUENTIAL OR INCIDENTAL LOSS
       OR DAMAGE (WHETHER FOR LOSS OF PROFIT OR OTHERWISE) AND WHETHER
       OCCASIONED BY THE NEGLIGENCE OF THE RESPECTIVE PARTIES, THEIR EMPLOYEES
       OR AGENTS OR OTHERWISE WHETHER OR NOT THEY HAVE BEEN ADVISED OF THE
       POSSIBILITY OF SUCH DAMAGES.

14.    REGULATORY APPROVALS

14.1   Any and all INDAs, NDAs and other applications for regulatory approval
       filed hereunder for the Product(s) shall be the responsibility and
       property of Lilly. Lilly shall allow Emisphere access thereto to enable
       Emisphere to fulfill its obligations and exercise its rights under this
       Agreement. Lilly will be responsible for all regulatory filings in all
       countries and shall allow Emisphere access to related correspondence, to
       the extent such access is necessary to enable Emisphere to fulfill its
       obligations and exercise its rights under this Agreement. In particular,
       Lilly agrees to inform Emisphere should any such correspondence
       reasonably pertain to the Emisphere Technology or the Emisphere Program
       Technology. The Parties shall collaborate in relation to obtaining the
       approval of the FDA for final approved labeling.

14.2   Save as otherwise outlined in this Agreement, the costs and expenses of
       any filings and proceedings made by Lilly to the FDA, including post
       approval studies required by the FDA in respect of the Product(s), and to
       maintain the FDA approval hereunder shall be paid by Lilly.

14.3   Lilly shall indemnify and hold harmless Emisphere, its agents and
       employees from and against all claims, damages, losses, liabilities and
       expenses to which Emisphere, its agents, and employees may become subject
       related to or arising

       out of Lilly's bad faith, gross negligence or intentional misconduct in
       connection with the filing or maintenance or failure to file or maintain
       or prosecute the NDA.

14.4   Subject to the provisions of Clause 14.4, it is hereby acknowledged that
       there are inherent uncertainties involved in the registration of
       pharmaceutical products with the FDA insofar as obtaining approval is
       concerned and such uncertainties form part of the business risk involved
       in undertaking the form of commercial collaboration as set forth in this
       Agreement. Therefore, save for using its reasonable efforts, Lilly and
       Emisphere shall have no liability to each other solely as a result of any
       failure of the Product(s) to achieve the approval of the FDA, or any
       other regulatory body in the Territory.

14.5   Should the Parties receive a notice of regulatory inspection from any
       governmental agency, or if the Parties receive notice of any potential
       regulatory action, relative to the Carrier, the Parties will have an
       obligation to notify each other of same.

       Emisphere will prepare and provide Lilly with all information deemed
       necessary by Lilly for worldwide regulatory submission of the Product
       (Lilly will provide Emisphere with a template for such submissions, which
       Emisphere shall prepare and provide the relevant information to Lilly).
       Emisphere shall also provide Lilly with necessary access to any
       regulatory filings worldwide relevant to the Product and Lilly shall be
       entitled to use the information contained therein in its own regulatory
       filings on the Product. Should Emisphere wish, at any time during the
       term of this Agreement, to modify its regulatory filings relating to the
       Product, Emisphere shall provide Lilly with written notification of its
       intentions prior to making such modification. Any proposed modification
       not required by law, government or regulatory agency must be responded to
       by Lilly within thirty (30) days. If Lilly's response is not received by
       Emisphere within 30 days, approval of such proposal shall be deemed to
       have been granted. Finally, to the extent details of the regulatory
       filing process are not set forth in this section or elsewhere in the
       Agreement, the Steering Committee shall decide any such matters.

15.    INSURANCE

15.1   Lilly shall maintain comprehensive general liability insurance, including
       product liability insurance on the Product(s) manufactured and/or sold in
       such prudent amount as shall be determined by Lilly management for the
       duration of this Agreement and for a period of two (2) years thereafter.

15.2   Emisphere shall maintain comprehensive general liability insurance,
       including product liability insurance on the Carrier(s) manufactured for
       and/or sold to Lilly in such prudent amount as shall be determined by
       Emisphere management for the duration of this Agreement and for a period
       of two (2) years thereafter. Emisphere shall also provide Lilly with a
       vendor's certificate for the Carriers substantially in a form to be
       agreed between the Parties.

16.    IMPOSSIBILITY OF PERFORMANCE - FORCE MAJEURE

16.1   Neither Party to this Agreement shall be liable for delay in the
       performance of any of its obligations hereunder if such delay results
       from causes beyond its reasonable control, including, without limitation,
       acts of God, fires, strikes, acts of war, or intervention of a government
       authority, non availability of raw materials, but any such delay or
       failure shall be remedied by such Party as soon as practicable.

17.    SETTLEMENT OF DISPUTES; PROPER LAW

17.1   The Parties will attempt in good faith to resolve any dispute arising out
       of or relating to this Agreement promptly by negotiation between the
       Chief Executive Officer of Emisphere and (a) the Vice President of
       Science, Technology and Proteins if the dispute is prior to Launch of
       Products in any country in the Territory, or (b) if the dispute arises
       after such Launch, then the Vice President of Lilly's general business
       unit responsible for the Product at issue. In the event that such
       negotiations do not result in a mutually acceptable resolution, the
       Parties agree to consider other dispute resolution mechanisms including
       mediation. Subject to the provisions of Clause 17.2, in the event that
       the Parties fail to agree on a mutually acceptable dispute resolution
       mechanism, any such dispute shall be finally settled by a court of
       competent jurisdiction. The Parties hereby submit to the jurisdiction of
       the state and Federal courts located in the state of New York.

17.2   This Agreement shall be governed by and construed in accordance with the
       laws of New York without reference to conflicts of laws principles.

18.    ASSIGNMENT

18.1   This Agreement may not be assigned by either Party without the prior
       written consent of the other, which consent shall not be unreasonably
       withheld, conditioned or delayed, save that either Party may assign this
       Agreement to its Affiliate or to any successor by merger or sale of
       substantially all of the assets of its business unit to which this
       Agreement relates without such consent, provided that such assignment
       does not have any adverse tax

       consequences on the other Party. Emisphere and Lilly will discuss any
       assignment by either Party to an Affiliate prior to its implementation in
       order to avoid or reduce any additional tax liability to the other Party
       resulting solely from different tax law provisions applying after such
       assignment to an Affiliate. For the purpose hereof, an additional tax
       liability shall be deemed to have occurred if either Party would be
       subject to a higher net tax on payments made hereunder after taking into
       account any applicable tax treaty and available tax credits than such
       Party was subject to before the proposed assignment.

       binding on either Party unless set forth in writing and executed by a
       duly authorized representative of each Party.

       constitute Emisphere and Lilly as partners, or Emisphere as an employee
       of Lilly, or Lilly as an employee of Emisphere. Neither Party hereto
       shall have any express or implied right or authority to assume or create
