3.   AGREEMENT WITH ELI LILLY AND COMPANY

     During February 1997, the Company and Eli Lilly and Company ("Lilly")
     entered into a strategic alliance (the "Lilly Strategic Alliance").  The
     terms of the Lilly Strategic Alliance provide for Lilly to fund certain
     research conducted by the Company on behalf of Lilly. Lilly has agreed to
     fund this research for a period of 18 to 24 months.  Lilly has a right to
     license the Company's technology and should the Company's research be
     successful, the Company would be entitled to receive fees, milestone
     payments and royalties.


4.   IMPACT OF THE FUTURE ADOPTION OF RECENTLY ISSUED ACCOUNTING STANDARD

     During February 1997, the Financial Accounting Standards Board issued
     Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS 128").
     SFAS 128 will require the Company to replace the current presentation of
     "primary" per share data with " basic" and "diluted" per share data. Since
     the impact of outstanding common stock equivalents on per share data is
     antidilutive, the future adoption of SFAS 128 will not have a material
     impact on the Company's per share data. SFAS 128 will be adopted by the
     Company for periods ending  after December 15 1997.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITIONS AND
         RESULTS OF OPERATIONS.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

       Certain statements under the caption "Management's Discussion and
Analysis of Financial Conditions and Results of Operations" and elsewhere in
this report on Form 10-Q constitute "forward-looking statements" within the
meaning of the Private Securities Litigation Reform Act of 1995 (the "Reform
Act"). Such forward-looking statements involve known and unknown risks,
uncertainties and other factors which may cause the actual results, performance
or achievements of the Company to be materially different from any future
results, performance, or achievements expressed or implied by such forward-
looking statements. Such factors include, among others, the following:
uncertainties related to future test results and viability of the Company's
product candidates, which are in the early stages of development; the need to
obtain regulatory approval for the Company's product candidates; the Company's
dependence on partnerships with pharmaceutical and other companies to develop,
manufacture and commercialize products using the Company's drug delivery
technologies; the Company's dependence on the success of its joint venture with
Elan Corporation plc ("Elan") for the development and commercialization of an
oral heparin product and its strategic alliance with Eli Lilly and Company
("Lilly") for the development and commercialization of certain of Lilly's
therapeutic proteins; the risk of technological obsolescence and risks
associated with the Company's highly competitive industry; the Company's
dependence on patents and proprietary rights; the Company's absence of
profitable operations and need for additional capital; the Company's dependence
on others to manufacture the Company's chemical compounds; the risk of product
liability and policy limits of product liability insurance; potential liability
for human clinical trials; the Company's dependence on key personnel and the
quality, judgment and strategic decisions of management and other personnel;
uncertain availability of third-party reimbursement for commercial medical
products; general business and economic conditions; and other factors referenced
in the Company's report on Form 10-K for the fiscal year ended July 31, 1996.

GENERAL

     Emisphere is a drug delivery company focused on the discovery and
application of proprietary synthetic chemical compounds that enable the oral
delivery of therapeutic macromolecules and other compounds that are not
currently deliverable by oral means.  Since its inception in 1986, the Company
has devoted substantially all of its efforts and resources to research and
development conducted on its own behalf and through collaborations with
corporate partners and academic research institutions.  The Company has had no
product sales to date.  The major sources of the Company's working capital have
been proceeds from its initial public offering in 1989, a second public offering
in February 1993, private equity financing, the latest of which occurred with an
affiliate of Elan in October 1995, reimbursement of expenses and other payments
from corporate partners, the registered sale of one million shares of Common
Stock to two institutional investors in April 1996, and income earned on the
investment of available funds.  The Company's operations are not significantly
affected by inflation or seasonality.

     On February 27, 1997, the Company and Lilly announced that they entered
into a strategic alliance (the "Lilly Strategic Alliance") to utilize
Emisphere's technologies for the improved delivery of certain Lilly therapeutic
proteins with a focus on oral delivery. The major therapeutic focus of the
collaboration is in the area of endocrinology, including growth disorders.
Initially, Lilly is committing limited funds to the Company for research on
delivery of two proteins. The Lilly Strategic Alliance contemplates that Lilly
may ultimately exercise options to license the applicable carriers and market
the products utilizing the combined technologies. If the options are exercised,
the Company may receive from Lilly milestone and other payments aggregating,
together with initial funding, up to $60 million, as well as future royalty
payments. The Lilly Strategic Alliance also contemplates that the Company could
receive further payments for other delivery applications if the focus of the
Lilly Strategic Alliance is expanded beyond the two specified therapeutic
proteins or to non-oral applications.

RESULTS OF OPERATIONS

     The Company has since its inception generated significant losses from
operations.  The Company does not expect to achieve profitability in the
foreseeable future.  Profitability will ultimately depend on the Company's
ability, either alone or in conjunction with third parties, to develop and
commercialize products utilizing the Company's technology.  There can be no
assurance that the development will be completed or if completed, any regulatory
agency will approve the final product.  Even if final products are developed and
approved, there is no assurance that sales will be sufficient to achieve
profitability.   If development of such products is not achieved or approval not
granted, the Company's prospects will be materially affected.

     The ability of the Company to reduce its operating losses in the near term
will be dependent upon, among other things, its ability to attract new
pharmaceutical and other companies who are willing to provide funding to the
Company for a portion of the Company's research and development with respect to
specific projects.  While the Company is constantly engaged in discussions with
pharmaceutical 

                                       9
<PAGE>
 
and other companies, there can be no assurance that the Company will enter into
any additional agreements or that the agreements will provide research and
development revenues to the Company.

THREE MONTHS ENDED JANUARY 31, 1997 VS. THREE MONTHS ENDED JANUARY 31, 1996:

For the three months ended January 31, 1997, the Company recognized $535,000 of
research and development revenue compared to $3,033,000 for the three months
ended January 31, 1996.  Research and development revenue for the three months
ending January 31, 1997 consisted of the recognition of revenues from the Elan-
Emisphere Joint Venture of approximately $386,000 and payments from two
pharmaceutical companies for which the Company performed feasibility studies.
For the three months ending January 31, 1996 revenue consisted of the
recognition of payments under the Company's agreements with Elan ($3,000,000)
and Pasteur Merieux ("Pasteur"). The recognition of the revenue from Elan was
for work Emisphere performed on the development of an oral Heparin USP
formulation prior to entering into the Elan-Emisphere Venture. Revenue
recognized from Pasteur was a payment for Emisphere's completion of a defined
milestone as called for in its feasibility agreement with Pasteur.

Total operating expenses for the three months ended January 31, 1997, increased
by  $1,104,000, or 52%, as compared to the three months ended January 31, 1996.
The details of this increase are as follows:

Research and development costs increased by approximately $364,000, or 24%, in
the three months ended January 31, 1997, as compared to the three months ended
January 31, 1996. This increase is mainly attributable to increased personnel
and related expenses associated with the Company's development of an oral
heparin formulation.  The Company also experienced an increase in funding of
outside consultants and universities engaged to conduct studies to help advance
the Company's scientific research efforts.  The Company believes that this level
of research and development spending will continue for the foreseeable future
and may increase if operations are expanded.

The increase of $306,000 in the loss in Elan-Emisphere Venture represents the
Company's pro-rata portion of the Venture's loss for the period.  No loss was
experienced in the comparable period as the Venture did not commence operations
until September 1996.

General and administrative expenses increased by approximately $434,000, or 71%,
in the three months ended January 31, 1997, as compared to the three months
ended January 31, 1996.  This increase is primarily the result of increased
legal and professional fees incurred in connection with the finalization of the
Elan-Emisphere Venture and the agreement with Lilly. This was partially offset
by a decrease in payments made to an outside consultant who assisted the Company
in discussions and negotiations with pharmaceutical companies.

The Company's other income in the three months ended January 31, 1997 increased
by approximately $17,000, or 7%, as compared to the three months ended January
31, 1996.  The increase was primarily due to better returns on the Company's
larger investment portfolio.

Based on the above factors, the Company's net loss for the second quarter of
fiscal 1997 totaled $2,429,000, as compared to $1,157,000 net income for the
1996 fiscal quarter.

SIX  MONTHS ENDED JANUARY 31, 1997 VS. SIX MONTHS ENDED JANUARY 31, 1996:

For the six months ended January 31, 1997, the Company recognized $2,530,000 of
research and development revenue compared to $3,033,000 for the six months ended
January 31, 1996. Research and development revenue for the six months ending
January 31, 1997 consisted of $2,381,000 from the Elan-Emisphere Venture in
connection with the development of an oral formulation of heparin and $149,000
from two pharmaceutical companies for which the Company performed feasibility
studies. Research and development revenue for the six months ending January 31,
1996 consisted of recognition of payments under the Company's agreements with
Elan ($3,000,000) and Pasteur. The recognition of the revenue from Elan was for
work Emisphere performed on the development of an oral formulation of heparin
prior to entering into the strategic alliance with Elan. Revenue recognized from
Pasteur was a payment for Emisphere's completion of a defined milestone as
called for in its feasibility agreement with Pasteur.

Total operating expenses for the six month period ended January 31, 1997,
increased by approximately $2,361,000, or 57%, as compared to the six month
period ended January 31, 1996.  The details of this increase are as follows:

                                       10
<PAGE>
 
Research and development costs increased by approximately $642,000, or 22%, for
the six months ended January 31, 1997, as compared to the six months ended
January 31, 1996. This increase is mainly attributable to increased personnel
and related expenses associated with the Company's development of an oral
heparin formulation.  The Company also experienced an increase in funding of
outside consultants and universities engaged to conduct studies to help advance
the Company's scientific research efforts.  The Company believes that this level
of research and development spending will continue for the foreseeable future
and may increase if operations are expanded.

The increase of $1,298,000 in the loss in Elan-Emisphere Venture represents the
Company's pro-rata portion of the Venture's loss for the period. No loss was
experienced in the comparable period as the Venture did not commence operations
until September 1996.

General and administrative expenses increased by approximately $422,000, or 34%,
for the six months ended January 31, 1997, as compared to the six months ended
January 31, 1996.  This increase is attributable to an increase in legal and
professional fees incurred in connection with the finalization of the Elan-
Emisphere Venture and the agreement with Lilly. This was partially offset by a
decrease in payments made to an outside consultant who assisted the Company in
discussions and negotiations with pharmaceutical companies.

The Company's other income in the six months ended January 31, 1997 increased by
approximately $213,000, or 72%, compared to the six months ended January 31,
1996.  This was primarily the result of a larger investment portfolio and better
returns.  In addition, the Company realized losses of approximately $41,000 on
the sale of investment securities during the six months ended January 31, 1996,
whereas no losses were incurred during the six months ended January 31, 1997.
Based on the above factors, the Company sustained a net loss for the six months
ended January 31, 1997 of  $3,435,000, as compared to a net loss of $783,000 for
the six months ended January 31, 1996.

LIQUIDITY AND CAPITAL RESOURCES

     As of January 31, 1997, the Company had working capital of approximately
$16,578,000 as compared with approximately $17,799,000 at July, 31, 1996.  Cash
and cash equivalents and marketable securities were approximately $15,868,000 as
of January 31, 1997, as compared to approximately $18,237,000 at July 31, 1996.
The decrease in the Company's cash and cash equivalents and marketable
securities was primarily due to cash used to fund operations in the first half
of fiscal 1997, partially offset by the exercise of options and reimbursement
from the Elan-Emisphere Venture for certain development costs.

     The Company expects to enter into a ten-year noncancelable lease for new
office and laboratory space commencing August 1997. The annual minimum rental is
anticipated to be approximately $1,300,000. Build-out cost for this space, net
of amounts to be paid by the landlord, are expected to total approximately
$3,000,000.

     The Company expects to continue to incur substantial research and
development expenses associated with the development of the Company's oral drug
delivery system. As a result of the ongoing research and development efforts of
the Company, management believes that the Company will continue to incur
operating losses and that, potentially, such losses could increase. The Company
expects to need substantial resources to continue its research and development
efforts. In addition, the Company is obligated to fund one-half of the Elan-
Emisphere Venture's cash needs upon the Venture's request. Such funding is
expected to commence in the near future and is expected to total approximately
$2,000,000 during the next 12 months. The Company and Elan are sharing the
financial benefits and expense obligations of the Venture on a 50/50 basis. The
Company expects the research funding from Lilly to approximate the costs to be
incurred by the Company in connection with the development of the Lilly
therapeutic proteins. Under present operating assumptions, the Company expects
that cash, cash equivalents and marketable securities will be adequate to meet
its liquidity and capital requirements through the third quarter of fiscal 1998.
Thereafter, the Company would need to seek additional funds, primarily in the
public and private equity markets and, to the extent necessary and available,
through debt financing. The Company has no firm agreements with respect to any
additional financing and there can be no assurance that the Company would be
able to obtain adequate funds on acceptable terms. If adequate funds were not
available, the Company would be required to delay, scale back, or eliminate one
or more of its research or development programs, or obtain funds, if available,
through arrangements with collaborative partners or others that may require the
Company to relinquish rights to certain of its technologies, product candidates,
or products that the Company would not otherwise relinquish. The Company does
not maintain any credit lines with financial institutions.

ITEM 5.  OTHER INFORMATION
         -----------------

     In February 1997, the Company and Lilly entered into a Research
Collaboration and Option Agreement (the "Lilly Agreement") to combine Lilly's
therapeutic protein and formulation capabilities with the Company's carrier
technologies.

     The Lilly Agreement provides initially for payments to the Company to fund
a research and development program (the "Program") to study the use of the
Company's technologies to develop oral and non-oral methods of delivering
formulations of two of Lilly's therapeutic proteins (the "Subject Proteins") in
the area of endocrinology, including growth disorders. The Lilly Agreement
represents the vehicle through which Lilly and the Company may together
develop and market orally deliverable products based on the Subject Proteins and
the Company's carrier technologies (the "Lilly Products"). The term of the
Program is 18 to 24 months.  Any extensions must be approved by the
Company and Lilly. If Lilly decides to expand the scope of the Program, payments
will be increased.

     Pursuant to the Lilly Agreement, the Company has granted to Lilly a series
of options (the "Options"), each to acquire an exclusive, worldwide license to
use the Company's technologies to develop one of the Lilly Products. Options
relating to the two of the Subject Proteins expire from one to two years from
the date of the Lilly Agreement, subject to certain extensions. Lilly's exercise
of the Options as to one of the Subject Proteins is mandatory upon satisfaction
of specified conditions. During the respective option periods, the Company has
agreed not to license its technologies to anyone other than Lilly for the
purpose of delivering the Subject Proteins.

     Upon exercise of an Option, the Company and Lilly will enter into a license
agreement (each a "License Agreement") granting Lilly a license to use the
Company's technologies to develop Lilly Products to deliver the Subject Protein
by a particular route of delivery. The Lilly Agreement and the License
Agreements will provide for payments of initial fees and milestone payments of
up to $60 million in the aggregate, as well as royalty payments if a Lilly
Product to which the License Agreement relates is sold commercially. The License
Agreements will further provide that Lilly is obligated to seek to market the
Lilly Products and that the Company is obligated to provide a material portion
of the supply of carrier necessary for the production of any such Lily Products.

     The Lilly Agreement further provides Lilly with a right of first refusal to
make an offer to enter into a license to use the Company's technologies for the
delivery of a limited number of other therapeutic proteins and peptides, or,
after the expiration of the option period, for the delivery of the Subject
Proteins (if not already licensed). The right of first refusal allows Lilly to
obtain the license if it exceeds a third-party offer by a specified premium. The
right of first refusal expires on February 26, 1998, subject to certain rights
to extend. The Lilly Agreement also contemplates the possibility of a continuing
relationship for the development of delivery systems for other therapeutic
proteins.

     Under the Lilly Agreement, the Company will own all patents, patent
applications, and other proprietary expertise relating to its technologies that
it develops as well as any material Lilly improvements or additions to the
Company's technologies, and Lilly will own all patents, patent applications and
other proprietary expertise relating to the therapeutic uses of its proteins (to
the extent invented during the Program). If Lilly makes recommendations,
suggestions or has discussions with the Company that result in a material
addition to or improvement of the Company's technologies, then Lilly may, in
certain circumstances, obtain limited preferences with respect to licenses for
Emisphere technologies covering Lilly proteins or products not included in the
Lilly Products.

     In addition, the Lilly Agreement includes a standstill provision pursuant
to which Lilly has agreed, with certain exceptions, not to acquire shares of the
Company's outstanding voting stock above a specified limit during a period
ending less than five years from the date of the Lilly Agreement.

               -------------                                                  
on a research and development program (the "Program") to research the use of the
                                            -------                             
Emisphere Technology for oral delivery (the "Oral Route") of      [***]  
                                             ----------

molecule and all active fragments, analogs,   [***]  -like peptides with primary
function similar to the  [***]  molecule              [***]
("  [***]  ") as                           [***]
                               [***]                                            
                               [***]                                    
                               [***]                                            
       [***]          (the "Non-Oral Routes") of proteins, all as more
                            ---------------
specifically set forth in Exhibit A attached hereto. Emisphere will make
available to Lilly access to all Emisphere Technology relevant for the Program.

          1.2  Program Management.  Lilly and Emisphere shall establish a
               ------------------                                        
steering committee (the "Steering Committee").  The function of the Steering
                         ------------------                                 
Committee shall be to plan, coordinate and manage the Program.  The Steering
Committee is not intended to replace any internal management procedures of
either party or continued and close collaboration by the parties with respect to
the Program. Rather, it is intended to be a vehicle to ensure that the Program
proceeds in a timely, coordinated, and well-planned fashion.  It shall be made
up of up to   [***]  members, with an equal number appointed by each of Lilly 
and Emisphere and with a central contact person appointed by each party. Each
party hereto shall name one member to be a co-chairperson of the Steering
Committee. On at least a quarterly basis, the Steering Committee shall meet to
review the results of the Program and to approve a work plan, based on the
Program as outlined in Exhibit A, for the ensuing quarter. The work plan for the
first quarter of the Program is set forth in Exhibit A. The Steering Committee
shall keep minutes of its meetings, shall act by a majority vote of its members
and shall be responsible for the development and implementation of the work
plan. Finally, meetings of the Steering Committee will alternate between
Emisphere's designated facility and Lilly's designated facility. Each party will
bear all expenses associated with attendance of its own employees at such
meetings held at the other party's designated facility. Work on the Steering
Committee (including attendance of its meetings) by Emisphere employees shall be
included in the Program work compensated by Lilly pursuant to Section 1.4,
below.

          1.3  Term; Termination; Damages.
               -------------------------- 

               (a) The Program shall continue for      [***]      from the date
hereof (the "Term"); provided that the Steering Committee shall have an option
             ----    --------                                                 
(the "Extension Option") to extend the Program for an additional    [***]   (the
      ----------------                                                          
"Extension Period").  If the Steering Committee decides to terminate the Program
 ----------------                                                               
at the end of the Term, the Program shall be terminated by written notice to
Emisphere and Lilly; in all other cases the Extension Option shall be deemed to
have been exercised.

               (b) Lilly and Emisphere must mutually agree if the Program is to
be extended beyond the Extension Period.

                                                                               3

               (c) Either party may terminate this Agreement upon written notice
to the other party that such party has breached this Agreement if, within 60
days of receipt of such notice such breach has not been cured.

               (d) Lilly hereby acknowledges and agrees that any breach by it of
this Agreement would cause irreparable injury to Emisphere, that money damages
alone would not provide an adequate remedy to Emisphere, and that, therefore,
Emisphere shall have the right to receive all payments from Lilly contemplated
hereunder           [***]             as liquidated damages in the event of
termination due to Lilly's breach.               [***]                          
                                 [***]                                       
                                 [***]                                      
                                 [***]                                  
            [***]                               

               (e) Termination or expiration of this Agreement shall not affect
the rights and obligations of the parties accrued hereunder prior to termination
or expiration. To avoid doubt, it is hereby confirmed that termination of this
Agreement by Lilly because of a breach by Emisphere shall not affect Lilly's
options as set forth in Article II or Lilly's Right of First Refusal as set
forth in Article III. To further avoid doubt, if Emisphere terminates this
Agreement because of a breach by Lilly, Lilly's rights under Articles II and III
shall be terminated. However, termination of this Agreement shall not affect any
license entered into pursuant to such options and Right of First Refusal
(whether Lilly or Emisphere is the terminating party).

          1.4  Payments.
               -------- 

               (a) Lilly shall pay to Emisphere $         [***]        (the
"Minimum Payments") for  [***]  hours of work (a rate of  [***]  FTE) per 
 ----------------
quarter to be performed for the Program by Emisphere. The first Minimum Payment
shall be paid by wire transfer of immediately available funds within thirty (30)
days of the Effective Date of this Agreement, and subsequent Minimum Payments
shall be paid by wire transfer of immediately available funds on or before each
three-month anniversary of the Effective Date of this Agreement during the Term
and, if applicable, the Extension Period.

               (b) "FTE" means a full-time equivalent scientific person year, or
                    ---
a total of  [***]  or  [***]  person hours per year of scientific and/or
technical work, on or directly related to the Program, carried out by an
Emisphere employee having at least a Bachelors Degree in science, or experience
equivalent thereto. Scientific work on or directly related to the Program to be
performed by Emisphere can include, but is not limited to, experimental
laboratory work, recording and writing up results, reviewing literature and
references, holding scientific

                                                                               4

discussions, managing and leading scientific staff, and carrying out Program
management duties or such other activities as may be appropriate to the conduct
of the Program.

               (c) Emisphere shall provide Lilly on a semi-annual basis during
the Term of the Program a report detailing how Emisphere allocated FTE's to the
Program. Such report shall provide Lilly with the names of the Emisphere
employees who make up the FTE's and the amount of each employee's time devoted
to the Program. Emisphere shall, further, maintain records in reasonable detail
and in accordance with generally accepted accounting principles ("GAAP") of all
                                                                  ----         
monies paid by Emisphere for research under the Program and shall provide Lilly,
within     [***]    days of the end of each semi-annual period, with a report
stating the dollar amount of funds supplied by Lilly that were expended on
research activities during the six 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. To the extent           [***]  
         of Program work have not been completed by Emisphere's employees, or
have been completed in a negligent manner, Emisphere shall give credit to Lilly
at the rate of $  [***]  per hour for each hour of shortfall or negligent work.
Such credit shall either be reimbursed to Lilly by wire transfer to a bank
account designated by Lilly and/or applied to Lilly's next quarterly minimum
payment. Such credit shall be made within  [***]  days after the above semi-
annual report is due to Lilly. Lilly shall be entitled to any tax credits due on
account of research and development expenses, to the extent permitted by law,
for the Program funds paid by Lilly. Also, Lilly may have the costs of research
and development programs audited in accordance with Section 5.19.

               (d) If Lilly desires to expand research beyond the scope of the
Program, if acceptable to Emisphere in its sole discretion, the parties hereto
will mutually agree upon the research programs to be added and the number of
FTE's necessary to achieve the objectives of the expanded research.  The
additional cost for each FTE shall be $    [***]     (indexed to the
    [***]    Consumer Price Index as published by the U.S. Dept. of Commerce in
    [***]    , adjusted annually) to be paid as follows: (i) an initial payment
shall be made on the next date a Minimum Payment is due, pro-rated for the
period between such day the FTE is added and the next quarterly payment due
pursuant to Section 1.4(a), above, and (ii) all subsequent payments shall be
made at the same time as the Minimum Payments.

               (e) While the right of first refusal set forth in Article III is
in effect, Lilly shall have the right to have Emisphere conduct feasibility
studies on the Right of First Refusal Compounds and shall reimburse Emisphere
for same at Emisphere's cost, insofar as Emisphere has the capacity to perform
such studies.

          1.5  Ownership of Data and Technology.
               -------------------------------- 

               (a) "Know-How" means all trade secrets, confidential scientific,
                    --------                                                   
technical and medical information, data and expertise from time to time
developed, produced, created or acquired by Lilly or Emisphere, as appropriate,
either prior to the Effective Date and pertaining to the Program or during the
term and in the course of carrying out the Program, including, but not limited
to, unpatented inventions, discoveries, theories, plans, ideas or designs
(whether or not reduced to practice).  To the extent that any of the items
listed above are acquired by either Emisphere or Lilly, they shall only fall
within the definition of Know-How hereunder to the extent to which there are no
obligations or restrictions in respect of such items which would prohibit
disclosure or use by Lilly or Emisphere, as appropriate.

               (b) Except as set forth in Sections 1.5(f) and (g) below,
Emisphere shall own all patents, patent applications and Know-How relating to
the Emisphere Technology that it invents and/or develops and any Lilly
Improvements.

               (c) It will not be Lilly's responsibility or intent to develop
new synthetic chemical compounds that enable the delivery of therapeutic
macromolecules and other compounds that are not currently deliverable by oral
means or by certain non-oral means (the "Carriers") as part of the Program. Any
new Carriers or inventions which are closely related to the Emisphere Technology
(as it exists as of the Effective Date) that arise, in whole or in part, out of
suggestions, recommendations or discussions held between Emisphere and Lilly
scientists shall be Emisphere Technology.

               (d) A "Lilly Improvement" shall be an improvement to Emisphere's
                      -----------------   
then-existing Emisphere Technology made by a Lilly employee as part of the
Program.

               (e) If Lilly makes recommendations, suggestions and/or has
discussions with Emisphere scientists that lead to a material addition to
Emisphere Technology pursuant to Section 1.5(c), above, or Lilly obtains a
material Lilly Improvement, Lilly will receive for any given protein (the
"Chosen Protein"), provided that the addition to Emisphere Technology and/or
 --------------   
Lilly Improvement at issue is applicable to the Chosen Protein(s), the right to
license all Emisphere Technology and the Lilly Improvement for the Chosen
Protein(s) at Lilly's discretion in accordance with any one of the following
milestone/royalty schedules (the "Chosen Protein Right"):

                                       [***]

     2)   The same terms as the Oral  [***]  Option set forth in Appendix 3, 
          hereto. Furthermore, in the event that Lilly, its Affiliates and sub-
          licensees together have a greater than  [***]  % share of the world
          market for the Chosen Protein(s), the  [***]  % royalty rate will 
          apply to only  [***]  % of Lilly's, its Affiliates' and its sub-
          licensees' cumulated net sales.

     3)   The same milestones as for the Oral  [***]  Option (set forth in 
          Appendix 1), with the following royalty rate schedule:  [***]  % for 
          net sales below the royalty step function target, and  [***]  % for 
          net sales above the target. The net sales targets for this Section
          are:

          Year                Target Net Sales     
          ----                ----------------
          1                   $    [***] 
          2                   $    [***] 
          3                   $    [***] 
          4 and beyond        $    [***] 

          Net Sales Targets will be adjusted annually based on changes in the
          Consumer Price Index published by the United States Department of
          Commerce, with a baseline of     [***]   .

     4)   Any other milestone/royalty schedule negotiated by the parties hereto
          in good faith.

The Chosen Protein(s) shall not include    [***]   or Right of First Refusal
Compounds.  The Chosen Protein Right shall apply to a maximum of   [***]  
proteins and shall expire  [***]  years from the Effective Date. Lilly shall 
not be permitted to choose more than                [***]                    
and shall be limited to a maximum of  [***]  proteins in any single year.
Furthermore, Lilly shall not be permitted to exercise this Chosen Protein Right
in the first year of this Agreement, even if there are Lilly Improvements.

The parties agree to negotiate in good faith whether or not an addition to
Emisphere Technology or a Lilly Improvement is material, taking into account the
size of the

                                                                               7

potential market and the value of the reduced payments to Emisphere. Examples of
the areas where such items may be material are:

     i)        [***]

     ii)       [***]

     iii)      [***]

     iv)       [***]

     v)        [***]

     vi)       [***]

     vii)      [***]

     viii)     [***]
               [***]

               (f) Lilly shall own all patents, patent applications and Know-How
relating to the therapeutic uses (specifically excluding Carrier delivery
systems) of [***] or any of its other proteins, to the extent that Lilly or
Emisphere invents same during the course of the Program.

               (g) Lilly shall own any toxicology or chemistry, manufacturing
and control data that it generates for the Program. If for reasons other than a
decision not to commercialize (i.e., for technical or other business reasons,
not for competitive reasons) the corresponding Product (as defined in Article
II), Lilly does not exercise any of the Options (as also defined in Article II)
granted pursuant to Article II, below, then Emisphere shall have the right to
purchase from Lilly all data generated by Lilly utilizing Emisphere Technology
      [***]      as verified by Lilly's standard accounting practices and
principles. To the extent Emisphere chooses not to purchase Lilly's data at
Lilly's     [***]   , Lilly agrees to consider negotiating with Emisphere
the sale of such data at a lower price. However, nothing set forth herein shall
require Lilly to sell Emisphere such data at such lower price. If because of its
determination not to commercialize (for competitive, as opposed to technical or
other business reasons) a Product Lilly fails to exercise any of the Options
granted pursuant to Article II, below, then Emisphere shall have the same right
to purchase access to Lilly's data set forth above. However, Emisphere's use of
those data under such circumstances shall be limited to its marketing efforts
with respect to securing another partner for development of the corresponding
Product(s). Emisphere shall own any data that it generates during the Program.

               (h) With respect to patents, patent applications and Know-How
invented and/or developed by Emisphere or Lilly during the course of the
Program, and to the extent the ownership of such patents, patent applications
and Know-How is not established in Sections 1.5(b), (c), (f) or (g), above,
ownership of such patents, patent applications and Know-How shall be as follows:

     i)   if made solely by an employee of Emisphere, Emisphere shall own such
          patents, patent applications and Know-How;

     ii)  if made solely by an employee of Lilly, Lilly shall own such patents,
          patent applications and Know-How;

     iii) if made jointly by employees of Lilly and Emisphere, Lilly and
          Emisphere shall each own an undivided one-half interest in such
          patents, patent applications and Know-How.

          1.6  Patent Applications - Emisphere.  Emisphere hereby covenants and
               -------------------------------                                 
agrees to undertake diligent efforts to file patent applications, to the extent
it deems advisable, within      [***]     of the Effective Date for the
existing Emisphere Technology in any country listed in Exhibit C attached hereto
in which it does not hold a patent, provided the filing of any such patent
applications is not barred by local law. In pursuing patent protection for
Emisphere Technology made pursuant to the Program, Lilly Improvements and/or any
inventions that fall within Section 1.5(h)(i), above, Emisphere will use the
same diligence it would apply to the pursuit of such protection for other
discoveries of similar importance.  Prior to the contemplated filing date,
Emisphere shall make a diligent effort to submit to Lilly a substantially
completed draft of any patent application Emisphere intends to file under this
Agreement.  Emisphere will make reasonable efforts to adopt Lilly's promptly
made suggestions, when appropriate in Emisphere's opinion, regarding any such
draft.  Furthermore, Emisphere will confer with Lilly regarding the prosecution
of pending patent applications and make reasonable efforts to adopt Lilly's
promptly made suggestions, when appropriate in Emisphere's opinion, regarding
the prosecution of such patent applications. Emisphere will send copies to Lilly
of any official actions and submissions with respect to such patent
applications.

           [***]           preparing, filing, prosecuting and maintaining
any patent applications and patents relating to the Emisphere Technology, Lilly
Improvements and/or any inventions that fall within Section 1.5(h)(i), above.
Should Emisphere not wish to file, prosecute, maintain or issue any patent
application, or maintain a patent issuing from any such patent application, in
any particular country, Emisphere will so notify Lilly of its intentions.  At
Emisphere's election, Lilly shall then have the right to file, prosecute, issue
and maintain such patent application or maintain such patent in the name of
Lilly.  Such patent application or patent, further, shall be owned by Lilly and
shall not be considered Emisphere Technology or a Lilly 
<PAGE>
 
                                                                               9

Improvement. Under no circumstances, however, shall Emisphere fail to file,
prosecute, maintain or issue any patent application, or maintain a patent
issuing from such application, in any particular country unless Lilly consents
to such failure on the part of Emisphere (such consent not to be unreasonably
withheld) or the right to file, prosecute, maintain and/or issue any such patent
application or patent has been granted to Lilly.

          1.7  Patent Applications - Joint Inventions.  With respect to any
               --------------------------------------                      
inventions that fall within Section 1.5(h)(iii), above, 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

          3.2  Notice of Final Offer.  In the event Emisphere receives an offer
               ---------------------                                           
from a third party (the "Offer") regarding a license to use the Emisphere
Technology for the delivery of any Right of First Refusal Compound, Emisphere
shall advise Lilly of the same within      [***]     of receiving such Offer.
Emisphere shall not be required to provide any documentation from the third
party to Lilly.  In the event Emisphere decides to accept the Offer, Emisphere
shall promptly deliver to Lilly a written notice of its intentions (the "Notice
                                                                         ------
of Intentions") and the basic terms and conditions of the proposed licensee's
- -------------

          3.3  Exercise of Right by Lilly.  Lilly shall then have     [***]   
from receipt of the Notice of Intentions to match the Offer.  Such right shall 
be exercisable by written notice delivered to Emisphere prior to the 
expiration of the 30-day period. In exercising its right, Lilly shall have the 
option to either match the Offer or present an offer with a     [***]   premium 
on all financial terms (e.g., royalty, milestones and signing fees).  If Lilly 
matches the Offer, Emisphere may continue negotiations with the third party 
with respect to an improved offer, provided that Lilly shall continue to have 
the right to match (or offer a premium as described below) such improved 
offer.  If Lilly makes an offer with the     [***]    premium over the Offer, 
such exercise shall allow Lilly immediately to obtain the rights for the 
particular Right of First Refusal Compound in discussion, cutting off all 
negotiations between Emisphere and the third party.  If the right of first 
refusal is exercised with respect to the Emisphere Technology for delivery of 
the Right of First Refusal Compound in the Offer, as specified in the Notice 
of Intentions, then Lilly shall enter into a binding letter of intent with 
respect to the terms of the Offer (or the premium terms) not more than     
[***]   after Emisphere's written acceptance of Lilly's exercise notice and 
shall make any required signing payments within    [***]   thereafter, with a 
full contract to follow.

               -----------------                                       
preferred partner for development of delivery systems for therapeutic proteins
for which Emisphere, on its own, is developing alternate delivery routes.

2.    GRANT OF RIGHTS

In consideration of the receipt of an 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 

                                       13
<PAGE>
 
      Appendix of the Option Agreement. If Emisphere does not receive payment
      from a sublicensee within   [***]   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   [***]   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 

                                       14

      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.

      Agreement or relevant Appendix, Emisphere shall provide Lilly on a
      quarterly basis during the term of the Research and Development Program a
      report, detailing 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 entitled to any tax credits
      due on account of research and development expenses, to the extent
      permitted by law, for the funds paid by Lilly to Emisphere hereunder.
      Also, Lilly may have the costs of the Research and Development Program
      audited in accordance with Clause 9.2.

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
      Product(s), Lilly shall be solely responsible and liable for 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
      all prevailing legislative and regulatory requirements of the countries
      where the Product(s) are manufactured and to be used.

7.    EXPLOITATION OF LICENSED TECHNOLOGY

7.1   Lilly will have the exclusive right to develop and/or exploit the Field.
      In order to commercialize the Product(s), Lilly shall use commercially
      reasonable efforts (consistent with its efforts on products of similar
      commercial importance) to obtain marketing approval for and Launch the
      Product(s) in such countries in the Territory as is determined by normal
      Lilly business practices.  It may be necessary to file an INDA or NDA and
      perform clinical testing in more than one country.  The conduct of such
      clinical trials and the obtaining of regulatory approvals shall be
      controlled and completed by Lilly.

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.

                                       17
<PAGE>
 
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.         [***]            
                                 [***] 
                                 [***]       
                                 [***]       
                                 [***]       
                                 [***]       
                                 [***]       
                                 [***]       
                                 [***]       
                                 [***]       
                                 [***]       

8.    FINANCIAL PROVISIONS

8.1   In consideration of the research and development work conducted by
      Emisphere for and on behalf of Lilly pursuant to the Research and
      Development Program, Lilly shall pay Emisphere the sums agreed to by the
      Parties pursuant to Clause 5.1, above, subject to the proper documentation
      of research and development work and expenses.

8.2   In consideration of the granting of a license of the Emisphere Technology
      to Lilly, Lilly shall make Milestone payments and pay royalties on Net
      Sales of the Product(s) at rates set forth in the Appendices of the Option
      Agreement.  The applicable Option Agreement Appendix, and hence Milestone
      and royalty schedule, shall be determined by reference to the Activation
      Letter.

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, 

                                       18
<PAGE>
 
      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.

                                       19
<PAGE>
 
8.10  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 certified 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.

                                       20
<PAGE>
 
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
               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 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, it shall first obtain Lilly's written
               consent, which consent shall not be unreasonably withheld.

                                      21
<PAGE>
 
      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 the Field or patentable Improvements
               developed 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 

                                      22
<PAGE>
 
      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 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

                                      23
<PAGE>
 
               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

                                      24
<PAGE>
 
               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 such Third Party claim, 
      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 

                                      25
<PAGE>
 
      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;

                                      26
<PAGE>
 
      (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 protection, pursuant to Clause 10
      hereof, for an invention developed as a result of the collaboration
      undertaken pursuant to this Agreement or (iii) to obtain institutional or
      government approval to test clinically 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                             [***]    
                                         [***]

      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 

                                      27
<PAGE>
 
      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  [***]
          [***]    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   [***]
            [***]     , 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       [***]        written notice, given
               within      [***]      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.

                                      28
<PAGE>
 
      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 addition to all other legal and
               equitable rights and remedies available hereunder, the option to
               terminate this Agreement upon      [***]        written notice,
               given within     [***]       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 full within        [***]        (or    [***]    if the
               information necessary to make such payment is not available
               within such  [***]  period) of the expiration or termination of
               this Agreement for the Territory or for such particular country
               or countries in the Territory, as the case may be;

      12.5.2   all confidentiality provisions set out herein shall remain in
               full 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
               Territory or in such particular country or countries in the
               Territory, as the case may be, (a) any valid and unexpired
               Emisphere Patents or Emisphere Program Patents and/or (b) any
               Emisphere Know-How or Emisphere Program Know-How that remains
               confidential or otherwise proprietary to Emisphere; and

                                      29
<PAGE>
 
      12.5.6   to the extent this Agreement is terminated (as opposed to
               expired) in the Territory or any particular country in the
               Territory, Lilly shall promptly make an accounting to Emisphere
               of the inventory of the Product(s) which it has in the Territory
               or for such particular country or countries in the Territory, as
               the case may be, if any, as of the date of such termination and
               Lilly shall have the right for a period of       [***]      after
               said termination to sell such inventory of the Product(s) in the
               Territory or in such particular country or countries in the
               Territory, as the case may be, or, if appropriate and legally
               permissible, to transport such inventory of Product(s) for sale
               in another country or countries in the Territory within such 
                 [***]  period; provided that the Net Sales thereof shall be
               subject to the royalty provisions of Clause 8 and so payable to
               Emisphere. Thereafter, any remaining inventory of 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
               Program Know-How for the Products in the Field in that country.
               Upon such conclusion of the term of this Agreement in any
               particular country,                  [***]
                                           [***]
                                           [***]
                                           [***]

12.6  Lilly shall have the option to terminate the Agreement upon    [***]
      prior written notice to Emisphere. Lilly shall pay for any and all
      external (to 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.

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 

                                      30
<PAGE>
 
      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 

                                      31
<PAGE>
 
      and all such inventors have irrevocably assigned all their rights and
      interests therein to Emisphere.

13.4  Emisphere represents and warrants that it is not aware of any information
      material to the examination of the Emisphere Patents that was not
      disclosed to the United States Patent Office.

13.5  Emisphere and Lilly represent and warrant for the benefit of each other
      that the execution of this Agreement by them and the full performance and
      enjoyment of the rights of them under this Agreement will not breach the
      terms and conditions of any license, contract, understanding or agreement,

      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)            [***]                
                                      [***]                                   
                                      [***]                                  
      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.

                                      35

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                  [***]                        

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      [***]       
      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.

      which when so executed shall be deemed to be an original and all of which
      when taken together shall constitute this Agreement.

20.8  Each of the Parties undertakes to do all things reasonably within its
      power which are necessary or desirable to give effect to the spirit and
      intent of this Agreement.

20.9  Each of the Parties hereby acknowledges that in entering into this
      Agreement it has not relied on any representation or warranty save as
      expressly set out herein or in any document referred to herein.

      shall either party release information which would allow a third party to
