                                INTERCARDIA, INC.

              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS


A.   Basis of Presentation

     The "Company" refers collectively to Intercardia, Inc. ("Intercardia") and
its majority-owned subsidiaries, CPEC, Inc., a Nevada corporation ("CPEC"),
Aeolus Pharmaceuticals, Inc., a Delaware corporation ("Aeolus"), and Renaissance
Cell Technologies, Inc., a Delaware corporation ("Renaissance"). As of June 30,
1998, Intercardia owned 80.1% of the outstanding stock of CPEC, 65.8% of the
outstanding stock of Aeolus and 79.6% of the outstanding stock of Renaissance.
Intercardia is a majority-owned subsidiary of Interneuron Pharmaceuticals, Inc.
("Interneuron"). As of June 30, 1998, Interneuron owned 61.9% of the outstanding
capital stock of Intercardia and the 19.9% of the outstanding stock of CPEC not
owned by Intercardia.

     The consolidated financial statements include the accounts of Intercardia
and its subsidiaries, CPEC, Aeolus and Renaissance. All significant intercompany
activity has been eliminated. The consolidated financial statements included
herein have been prepared by the Company without audit, pursuant to the rules
and regulations of the Securities and Exchange Commission ("SEC"). Certain
information and footnote disclosures normally included in financial statements
prepared in accordance with generally accepted accounting principles have been
condensed or omitted pursuant to such rules and regulations. In the opinion of
management, the accompanying unaudited consolidated financial statements include
all adjustments (consisting only of normal recurring adjustments) necessary to
present fairly the consolidated financial position, results of operations and
cash flows of the Company. The unaudited consolidated financial statements
included herein should be read in conjunction with the audited consolidated
financial statements and the notes thereto included in the Company's Annual
Report on Form 10-K for the fiscal year ended September 30, 1997 ("Fiscal 1997")
and in the Company's other SEC filings. Results for the interim period are not
necessarily indicative of the results for any other interim period or for the
full fiscal year. The Company's financial statements have been restated to
reflect the merger of Transcell Technologies, Inc. ("Transcell") and the Company
(see Note C).

B.   Recent Accounting Pronouncements

     The Company adopted Statement of Financial Accounting Standards ("SFAS")
No. 128, "Earnings Per Share", as of December 31, 1997. SFAS No. 128 replaced
the previously reported primary and fully diluted earnings per share with basic
and diluted earnings per share. Unlike primary earnings per share, basic
earnings per share excludes any dilutive effects of stock options and warrants.
Earnings per share amounts for all periods presented have been restated to
conform to SFAS No. 128 requirements. Due to the antidilutive effect of the
Company's outstanding stock options and warrants, there was no effect on the
earnings per share previously disclosed as a result of adopting SFAS No. 128.



                                       6
<PAGE>



     The Company will adopt SFAS No. 130, "Reporting Comprehensive Income", for
the fiscal year ending September 30, 1999. SFAS No. 130 establishes standards
for reporting and display of comprehensive income and its components in a full
set of general-purpose financial statements. Management believes its current
disclosures will not be affected by adopting SFAS No. 130.

     The Company will adopt SFAS No. 131, "Disclosures About Segments of an
Enterprise and Related Information", for the fiscal year ending September 30,
1999. SFAS No. 131 specifies revised guidelines for determining an entity's
operating segments and the type and level of financial information to be
disclosed. Management believes its current disclosures will not be affected by
adopting SFAS No. 131.

C.   Merger

     On May 8, 1998, Intercardia acquired all of the outstanding stock of
Transcell in a merger of Transcell with and into Intercardia and also acquired
certain related technology rights held by Interneuron in exchange for
Intercardia Common Stock with an aggregate market value of approximately
$14,200,000 (the "Merger"). In addition, Intercardia issued replacement stock
options and warrants to purchase approximately 260,000 shares of Intercardia
Common Stock to Transcell employees, consultants and warrant holders. The former
Transcell operation, which is now a division of Intercardia, is referred to as
Intercardia Research Laboratories ("IRL") and is conducting pharmaceutical
research and development utilizing carbohydrate-based combinatorial chemistry.

     Under the terms of the Agreement and Plan of Merger between Intercardia,
Transcell and Interneuron dated March 2, 1998 (the "Merger Agreement"),
Transcell stockholders will receive Intercardia Common Stock in three
installments. The first installment of 320,151 shares was issued upon closing
the transaction on May 8, 1998 (the "Closing"). The second and third
installments will each consist of approximately $3,000,000 of Intercardia Common
Stock, as valued at each issuance date, and will be issued in August 1999 and
February 2000. In exchange for certain license and technology rights held by
Interneuron, and for Interneuron's continuing guarantee of certain of
Transcell's lease obligations, Intercardia issued to Interneuron 174,672 shares
of Intercardia Common Stock at Closing with a value of $3,000,000 and will pay
Interneuron a royalty on net sales of certain products that may result from a
research collaboration (the "Merck Collaboration") originally entered into among
Transcell, Interneuron and Merck & Co., Inc. ("Merck").

     Prior to the Merger, Transcell was a majority-owned subsidiary of
Interneuron. The acquisition of Interneuron's 77.9% ownership interest in
Transcell has been treated in a manner similar to a "pooling-of-interests", as
it represented a transfer of stock between entities under common control, and
the acquisition of the non-Interneuron ownership interest has been accounted for
by using the "purchase" method of accounting. Upon Closing, the Company incurred
a charge to operations of $5,343,000 for the purchase of the non-Interneuron
portion of in-process research and development. All of Transcell's past results
of operations have been



                                       7
<PAGE>



combined with the results of operations of the Company, and the Company's
financial statements for all periods have been restated to reflect the Merger.

D.   Contract Disputes with Astra Merck

     The Company's collaboration (the "Astra Merck Collaboration") with Astra
Merck Inc. ("Astra Merck") provides that Astra Merck shall be responsible for
the Company's royalty obligation to Bristol-Myers Squibb Company ("BMS") and for
the expenses incurred in development and commercialization of the twice-daily
formulation of BEXTRA(R) (bucindolol HCl), and Astra Merck committed an amount
up to $15,000,000 to be expended in connection with such development. Astra
Merck has represented to the Company that it had expended $15,000,000 as of
April 30, 1998. The Company and Astra Merck are discussing Astra Merck's
contractual responsibility to fund such expenses above $15,000,000, while Astra
Merck has continued to fund such expenses. The Company believes that in the
event Astra Merck does not fund such expenses, Astra Merck would be in breach of
the Astra Merck Collaboration and lose the U.S. marketing rights to BEXTRA. The
Astra Merck Collaboration provides for arbitration of any disputes, and Astra
Merck has notified the Company that Astra Merck intends to institute arbitration
proceedings to resolve the dispute. Under the Astra Merck Collaboration, the
parties are required to attempt to resolve disputes prior to the actual
institution of arbitration proceedings. There can be no assurance as to the cost
or results of any arbitration.

     On July 1, 1998, the business of Astra Merck was combined with that of
Astra AB's wholly owned subsidiary, Astra USA, Inc. into a new limited
partnership, Astra Pharmaceuticals, L.P. ("Astra Pharmaceuticals"), and Astra
Pharmaceuticals has succeeded to the rights and obligations of Astra Merck under
the Astra Merck Collaboration. In August 1998, the Company notified Astra
Pharmaceuticals that the Company believes Astra Pharmaceuticals has breached
certain non-competition provisions of the Astra Merck Collaboration. The Company
and Astra Pharmaceuticals are in discussions to resolve the conflict or
terminate the Astra Merck Collaboration. Astra Pharmaceuticals has informed the
Company it does not believe it is in violation of the Astra Merck Collaboration.
If the Astra Merck Collaboration is terminated because of Astra Merck's breach,
the Astra Merck Collaboration provides for return of all rights, material and
information relating to BEXTRA to the Company and a payment to the Company.

E.   Subsequent Event

     In July 1998, Intercardia signed an agreement ("Opocrin Agreement") to
license a development compound ("OP2000") from Opocrin S.p.A., of Modena, Italy
("Opocrin"). Intercardia intends to investigate the use of OP2000 as a drug for
the treatment of inflammatory bowl disease. The license is worldwide except for
Japan and South Korea. Intercardia made a $1,000,000 payment to Opocrin, which
will be recognized as license fee expense in the Company's fourth quarter as the
compound is in the early stages of development, and will be responsible for
conducting clinical trials for OP2000. Intercardia is required to make
additional milestone payments to Opocrin upon initiation of Phase III clinical
trials, upon filing for regulatory approval, upon obtaining regulatory approval
and upon achieving specified annual sales.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
        of Operations.

Introduction

     Statements in this Form 10-Q that are not descriptions of historical facts
are forward-looking statements that are subject to risks and uncertainties.
Actual results could differ materially from those currently anticipated due to a
number of factors, including those set forth herein and in the Company's other
SEC filings, including, in particular, risks relating to future capital needs,
risks related to the Company's proposed arbitration with Astra Merck, dependence
on collaborative partners, competition, uncertainties relating to clinical
trials, the early stage of products under development, government regulations,
market acceptance and risks relating to acquisitions. The following discussion
should be read in conjunction with the unaudited consolidated financial
statements and notes thereto appearing elsewhere in this report, the audited
consolidated financial statements and the notes thereto included in the
Company's Annual Report on Form 10-K for Fiscal 1997 and the Company's other SEC
filings.

     The Company's strategy is to be a leader in the discovery, development and
commercialization of therapeutics for the treatment of cardiovascular,
pulmonary, infectious and other diseases. The Company's most advanced product is
BEXTRA, a compound currently in Phase III clinical trials for the treatment of
congestive heart failure.

     On May 8, 1998, Intercardia acquired all of the outstanding stock of
Transcell and certain related technology owned by Interneuron in exchange for
Intercardia Common Stock with an aggregate market value of approximately
$14,200,000. In addition, Intercardia issued Intercardia replacement stock
options and warrants to purchase approximately 260,000 shares of Intercardia
Common Stock to Transcell employees, consultants and warrant holders. Under the
terms of the Merger Agreement, Transcell stockholders will receive Intercardia
Common Stock in three installments. The first installment of 320,151 shares was
issued upon the Closing. The second and third installments will each consist of
approximately $3,000,000 of Intercardia Common Stock, as valued at each issuance
date, and will be issued in August 1999 and February 2000. In exchange for
certain license and technology rights owned by Interneuron, and for
Interneuron's continuing guarantee of certain of Transcell's lease obligations,
Intercardia issued to Interneuron 174,672 shares of Intercardia Common Stock at
Closing with a value of $3,000,000 and will pay Interneuron a royalty on net
sales of certain products that may result from the Merck Collaboration. Prior to
the Merger, Transcell was a majority-owned subsidiary of Interneuron. The
acquisition of Interneuron's 77.9% ownership interest in Transcell is treated in
a manner similar to a "pooling-of-interests" as it represented a transfer of
stock between entities under common control and the acquisition of the
non-Interneuron ownership interest is accounted for by using the "purchase"
method of accounting. Upon Closing, the Company incurred a charge to operations
of $5,343,000 for the purchase of the non-Interneuron portion of in-process
research and development. All of Transcell's past results of operations have
been combined with the results of operations of the Company, and the Company's
financial statements for all periods presented have been restated to reflect the
Merger.

     In July 1998, Intercardia signed the Opocrin Agreement to license OP2000
from Opocrin. Intercardia intends to investigate the use of OP2000 as a drug for
the treatment of inflammatory bowl disease. The license is worldwide except for
Japan and South Korea. Intercardia made a $1,000,000 payment to Opocrin, which
will be recognized as license fee expense in the Company's fourth quarter as the
compound is in the early stages of development, and will be responsible for
conducting clinical trials for OP2000. Intercardia is required to make
additional milestone payments to Opocrin upon initiation of Phase III clinical
trials, upon filing for regulatory approval, upon obtaining regulatory approval
and upon achieving specified annual sales.

     The Company is developing plans designed to address any "Year 2000" issues
in advance of December 31, 1999. The Company uses primarily a limited number of
third party software programs and systems in its operations, and it is currently
in the process of assessing which of those are vital to Company operations and
their Year 2000 compliance status. Any failure of such programs or systems, or
those of suppliers, service providers or collaborative partners, to resolve any
Year 2000 issues on a timely basis could result in a major system failure or
miscalculations. The Company is developing contingency plans designed to address
any failures that might occur. Although there can be no assurances, based upon
its assessments to date, the Company does not believe that it will encounter
Year 2000 problems or compliance costs that will have a material effect upon its
financial condition or results of operations.

Results of Operations

     The Company incurred net losses of $10,189,000 and $17,341,000 for the
three and nine months ended June 30, 1998, respectively, versus net losses of
$3,016,000 and $5,839,000 for the three and nine months ended June 30, 1997,
respectively. As a result of the Merger, the Company's financial statements for
all periods have been restated to include the results of operations of
Transcell.

     Contract and license fee revenue of $577,000 and $1,662,000 for the three
and nine months ended June 30, 1998, respectively, consisted primarily of
contract revenue payments from Merck pursuant to the Merck Collaboration and
from Astra Merck pursuant to the Astra Merck Collaboration. Contract and license
fee revenue of $523,000 and $3,820,000 for the three and nine months ended June
30, 1997, respectively, consisted primarily of contract revenue payments
received from BASF Pharma/Knoll AG ("Knoll") pursuant to the Company's
collaboration with Knoll (the "Knoll Collaboration") and from Astra Merck
pursuant to the Astra Merck Collaboration.

     The Company continues to increase its R&D operations in all of its research
and development programs. R&D expenses increased by $2,063,000 (76%) to
$4,760,000 for the three months ended June 30, 1998 from $2,697,000 for the
three months ended June 30, 1997. The increase in R&D expenses for the three
months was due to increased IRL expenses of $1,387,000, increased bucindolol and
general development expenses of $366,000, increased Aeolus expenses of $133,000
and increased Renaissance expenses of $177,000.



                                       10
<PAGE>



     R&D expenses increased by $3,926,000 (56%) to $10,896,000 for the nine
months ended June 30, 1998 from $6,970,000 for the nine months ended June 30,
1997. The increase in R&D expenses for the nine months was due to increased IRL
expenses of approximately $1,916,000, increased bucindolol and general
development expenses of approximately $710,000, increased Aeolus R&D expenses of
approximately $807,000 and increased Renaissance R&D expenses of approximately
$493,000.

     IRL R&D expenses increased by $1,387,000 (92%) to $2,898,000 for the three
months ended June 30, 1998 from $1,511,000 for the three months ended June 30,
1997. IRL R&D expenses increased $1,916,000 (48%) to $5,932,000 for the nine
months ended June 30, 1998 from $4,016,000 for the nine months ended June 30,
1997. Based on a review of Transcell's assets after the Merger, the Company
recorded a write-down of approximately $700,000 for property and equipment which
did not meet the Company's capitalization criteria. The other increases for the
three and nine months resulted from expenses related to expanded IRL operations,
including expenses of the Merck Collaboration and moving into new and larger
facilities in June 1997.

     The increases in bucindolol and general development expenses for the three
and nine months were primarily due to costs related to the development of BEXTRA
for Europe and additional R&D personnel expenses. The Astra Merck Collaboration
requires Astra Merck to pay for certain expenses related to the development of
the twice-daily formulation of BEXTRA for the United States. During the nine
months ended June 30, 1998, Astra Merck paid the Company contract revenue of
$633,000 and assumed liabilities on the Company's behalf of approximately
$4,800,000. From inception of the Astra Merck Collaboration through June 30,
1998, Astra Merck had assumed liabilities totaling approximately $14,606,000 on
the Company's behalf. These additional amounts did not flow through the
Company's Statements of Operations, as they were offset against related
expenses. As of June 30, 1998, the Company's Balance Sheet included
approximately $1,029,000 of accounts receivable due from Astra Merck and
approximately $671,000 of accrued expenses related to obligations assumed by
Astra Merck. See "--Liquidity and Capital Resources".

     Aeolus R&D expenses increased by $133,000 (35%) to $510,000 for the three
months ended June 30, 1998 from $377,000 for the three months ended June 30,
1997. Aeolus R&D expenses increased by $807,000 (94%) to $1,661,000 for the nine
months ended June 30, 1998 from $854,000 for the nine months ended June 30,
1997. The increases in Aeolus R&D expenses for the three and nine months were
primarily due to increases in sponsored research, contracted chemistry and
patent fees, as Aeolus has expanded its antioxidant small molecule research
program during the past year.

     Renaissance R&D expenses for its liver stem cell program for the three and
nine months ended June 30, 1998 were approximately $177,000 and $493,000,
respectively. Intercardia acquired 79.6% of the outstanding capital stock of
Renaissance in September 1997.

     During the three and nine months ended June 30, 1998, the Company incurred
charges to operations of $5,343,000 for the purchase of the non-Interneuron
portion of Transcell in-process research and development in the Merger discussed
above.



                                       11
<PAGE>



     General and administrative ("G&A") expenses decreased by $269,000 (26%) to
$782,000 for the three months ended June 30, 1998 from $1,051,000 for the three
months ended June 30, 1997. G&A expenses were $2,938,000 for both the nine
months ended June 30, 1998 and June 30, 1997. The decrease in G&A expenses for
the three months and the flat G&A expenses for the nine months reflect the
discontinuance of IRL's G&A operating expenses in May 1998 as a result of the
Merger, as IRL's administrative functions are handled by Intercardia's
headquarter operations.

     The minority interest in the Consolidated Statement of Operations for the
three and nine months ended June 30, 1997 related to the 19.9% minority interest
of CPEC. There were no minority interest charges for the three and nine months
ended June 30, 1998.

Liquidity and Capital Resources

     As of June 30, 1998, the Company had cash, cash equivalents and marketable
securities of $22,441,000, which was $15,139,000 less than the balance at
September 30, 1997, primarily due to a $10,000,000 contract payment made
pursuant to the Astra Merck Collaboration in December 1997 in conjunction with
the development of BEXTRA in the United States and the funding of the Company's
operations for the nine month period ended June 30, 1998. Accrued expenses
decreased by approximately $11,526,000 to approximately $1,563,000, primarily
because the $10,000,000 Astra Merck payment was included in accrued expenses as
of September 30, 1997.

     The Company's cash, cash equivalents and marketable securities balance is
expected to continue to decrease during the remainder of the fiscal year ending
September 30, 1998 ("Fiscal 1998"), due primarily to (1) lower contract revenue
for Fiscal 1998 than Fiscal 1997, which included payments of approximately
$3,480,000 made by Knoll pursuant to the Knoll Collaboration, (2) a decrease in
investment income due to lower cash and marketable securities balances, and (3)
increased expenses due to expanded operations, including costs associated with
bucindolol development, clinical trials in Europe, a full year of operations for
Renaissance, potential funding of a portion of development costs for BEXTRA in
the United States and operating expenses of IRL subsequent to completion of the
Merger in May 1998.

     In connection with its acquisition of CPEC, the Company is committed to
provide certain support to the Phase III clinical trial for bucindolol, known as
the Beta-blocker Evaluation of Survival Trial (the "BEST Study"). The Astra
Merck Collaboration provides Astra Merck with U.S. marketing rights to the
twice-daily formulation of BEXTRA. The Astra Merck Collaboration provides that
Astra Merck shall be responsible for the Company's royalty obligation to BMS and
for the expenses incurred in development and commercialization of the
twice-daily formulation of BEXTRA in the United States, and Astra Merck
committed an amount up to $15,000,000 to be expended in connection with such
development. Astra Merck has represented to the Company that it had expended
$15,000,000 as of April 30, 1998. The Company and Astra Merck are discussing
Astra Merck's contractual responsibility to fund such expenses above
$15,000,000, while Astra Merck has continued to fund such expenses. The



                                       12

Company believes that in the event Astra Merck does not fund such expenses,
Astra Merck would be in breach of the Astra Merck Collaboration and lose the
U.S. marketing rights to bucindolol. The Astra Merck Collaboration provides for
arbitration of any disputes, and Astra Merck has notified the Company that Astra
Merck intends to institute arbitration proceedings to resolve the dispute. Under
the Astra Merck Collaboration, the parties are required to attempt to resolve
disputes prior to the actual institution of arbitration proceedings. There can
be no assurance as to the cost or results of any arbitration. The Company has
estimated that the remaining costs to complete the development of bucindolol in
the United States and prepare the New Drug Application ("NDA") for submission to
the U.S. Food and Drug Administration (the "FDA") could be $15,000,000 to
$20,000,000. In the event that the Company is required to fund such expenses, or
a portion of such expenses, its results of operations and financial position may
be materially adversely affected.

     Pursuant to the Astra Merck Collaboration, the Company paid Astra Merck
$10,000,000 in December 1997 (for which the Company made an accrual as of
September 30, 1997) and agreed to pay up to $11,000,000 for one-third of product
launch costs incurred beginning when the Company files an NDA for the
twice-daily formulation of bucindolol and continuing through the first 12 months
subsequent to the first commercial sale of the formulation. In the event the
Company elects not to make these payments, the royalties payable by Astra Merck
to CPEC will be substantially reduced.

     On July 1, 1998, the business of Astra Merck was combined with that of
Astra AB's wholly owned subsidiary, Astra USA, Inc. into a new limited
partnership, Astra Pharmaceuticals, who has succeeded to the rights and
obligations of Astra Merck under the Astra Merck Collaboration. In August 1998,
the Company notified Astra Pharmaceuticals that the Company believes Astra
Pharmaceuticals has breached certain non-competition provisions of the Astra
Merck Collaboration. The Company and Astra Pharmaceuticals are in discussions to
resolve the conflict or terminate the Astra Merck Collaboration. Astra
Pharmaceuticals has informed the Company it does not believe it is in violation
of the Astra Merck Collaboration. If the Astra Merck Collaboration is terminated
because of Astra Merck's breach, the Astra Merck Collaboration provides for
return of all rights, material and information relating to BEXTRA to the Company
and a payment to the Company. In such event, the Company would be responsible
for all remaining costs to develop BEXTRA in the United States.

     The Company will incur additional charges to operations relating to the
acquisition of CPEC in the event that certain milestones are achieved in the
development and commercialization of bucindolol. The Company will be required to
issue to the former CPEC stockholders shares of Interneuron's common stock, upon
achieving the milestones of filing an NDA and receiving an approval letter from
the FDA to market bucindolol. In exchange for Interneuron providing such shares,
the Company will pay Interneuron the value of such shares, in either cash or
Intercardia Common Stock, at the Company's option. Each additional payment would
have minimum and maximum charges to the Company of $750,000 and $1,875,000,
respectively.



                                       13

     Pursuant to the Knoll Collaboration, the Company is responsible for
approximately 40% of the development and marketing costs of bucindolol for all
countries with the exception of the United States and Japan (the "Knoll
Territory"), subject to certain maximum dollar limitations. The Company's
portion of development and clinical trials costs of the twice-daily formulation
of bucindolol for the Knoll Territory is estimated to be up to $10,000,000 and
the Company's portion of marketing costs prior to product launch is estimated to
be up to $4,000,000. Upon product launch, the Company will be responsible for
40% of the net loss in the Knoll Territory, if any, as defined. The Company is
also responsible for approximately 40% of the costs incurred to develop a
once-daily formulation of bucindolol for the Knoll Territory and approximately
67% of the once-daily development costs that have a worldwide benefit.

     The Company is aware of products available or in development by its
competitors that address the diseases being targeted by the Company. In
particular, carvedilol, a non-selective beta-blocker with moderate vasodilating
properties, is owned by Hoffmann-La Roche Inc. ("Roche") and licensed in the
United States and certain other countries to SmithKline Beecham ("SKB"). In May
1997, the FDA approved the use of carvedilol as a treatment for congestive heart
failure in the United States, and SKB and Roche are currently co-promoting
carvedilol in the United States and a number of other countries. The Company is
unable to predict the impact of this product on BEXTRA, if BEXTRA is approved by
the FDA. Carvedilol's approval for marketing as a treatment for congestive heart
failure in the United States prior to BEXTRA may have adversely affected the
patient enrollment rate of the BEST Study and could provide a marketing
advantage for carvedilol. In addition, in March 1998, Germany-based Merck KGaA
announced early termination of the CIBIS II trial to test bisoprolol as a
treatment in CHF patients in Europe. Merck KGaA reported that in the trial,
which enrolled 2,647 patients, those receiving bisoprolol had a higher survival
rate than patients receiving customary treatment. Bisoprolol is a beta-1
receptor selective beta-blocker marketed for hypertension in the United States
by Wyeth-Ayerst Laboratories, a subsidiary of American Home Products
Corporation.

     The Company expects to incur substantial additional costs and losses over
the next few years. The Company's working capital and capital requirements will
depend upon numerous factors, including: the progress of the development and
clinical trials of bucindolol; the status of the Astra Merck Collaboration,
including the resolution of proposed arbitration proceedings and whether the
Company assumes responsibility for all BEXTRA development costs in the United
States; the timing and cost of obtaining regulatory approvals; and the ability
of the Company to establish additional collaborative arrangements with other
companies to provide research or development funding to the Company and to
conduct clinical trials, obtain regulatory approvals, and manufacture and market
certain of the Company's products. The Company may acquire other products,
technologies or businesses that complement the Company's existing and planned
products, although the Company currently has no commitment or agreement with
respect to any such acquisitions. While the Company believes it has sufficient
cash available for currently planned expenditures through the fiscal year ending
September 30, 1999, excluding any additional bucindolol development costs the
Company may assume in connection with, or in the event of termination of, the
Astra Merck Collaboration, the Company intends to raise additional capital
through equity or debt financing prior to such time. However, there can be no
assurance such funds will be available on terms acceptable or favorable to the
Company, if at all. The



                                       14
<PAGE>



Company may require additional financing to fund the Company's operations, to
make payments to its collaborative partners, including up to $11,000,000 in
payments for U.S. product launch expenses to Astra Merck assuming the Astra
Merck Collaboration continues, to fund any additional costs incurred in
connection with the Astra Merck Collaboration and to fund 40% of development and
marketing costs of bucindolol in the Knoll Territory pursuant to the Knoll
Collaboration with Knoll, as well as to fund new business opportunities and
growth.

                                INTERCARDIA, INC.

                       1994 STOCK OPTION PLAN, AS AMENDED

1.   Purpose.

     The purpose of this plan (the "Plan") is to secure for INTERCARDIA, INC.
(the "Company") and its shareholders the benefits arising from capital stock
ownership by employees, officers and directors of, and consultants or advisors
to, the Company, the Company's parent, Interneuron Pharmaceuticals, Inc.
("Interneuron") and the Company's subsidiary corporations who are expected to
contribute to the Company's future growth and success. Those provisions of the
Plan which make express reference to Section 422 shall apply only to Incentive
Stock Options (as that term is defined in the Plan).

2.   Type of Options and Administration.

     (a) Types of Options. Options granted pursuant to the Plan shall be
authorized by action of the Board of Directors of the Company (or a Committee
designated by the Board of Directors) and may be either incentive stock options
("Incentive Stock Options") meeting the requirements of Section 422 of the
Internal Revenue Code of 1986, as amended or replaced from time to time (the
"Code") or non-statutory options which are not intended to meet the requirements
of Section 422 of the Code.

     (b) Administration. The Plan will be administered by the Board of Directors
or a committee (the "Committee") appointed by the Board of Directors of the
Company, whose construction and interpretation of the terms and provisions of
the Plan shall be final and conclusive. The delegation of powers to the
Committee shall be consistent with applicable laws or regulations (including,
without limitation, applicable state law and Rule 16b-3 promulgated under the
Securities Exchange Act of 1934 (the "Exchange Act"), or any successor rule
("Rule 16b-3")). The Committee may in its sole discretion grant options to
purchase shares of the Company's Common Stock, $.001 par value per share
("Common Stock"), and issue shares upon exercise of such options as provided in
the Plan. The Committee shall have authority, subject to the express provisions
of the Plan, to construe the respective option agreements and the Plan, to
prescribe, amend and rescind rules and regulations relating to the Plan, to
determine the terms and provisions of the respective option agreements, which
need not be identical, and to make all other determinations in the judgment of
the Committee necessary or desirable for the administration of the Plan. The
Committee may correct any defect or supply any omission or reconcile any
inconsistency in the Plan or in any option agreement in the manner and to the
extent it shall deem expedient to carry the Plan into effect and it shall be the
sole and final judge of such expediency. No director or person acting pursuant
to authority delegated by the Board of Directors shall be liable for any action
or determination under the Plan made in good faith. Subject to adjustment as
provided in Section 15 below, the aggregate number of shares of Common Stock
that may be subject to options granted to any person in a calendar year shall
not exceed 300,000 shares.



                                       1
<PAGE>



     (c) Applicability of Rule 16b-3. Those provisions of the Plan which make
express reference to Rule 16b-3 shall apply to the Company only at such time as
the Company's Common Stock is registered under the Exchange Act, subject to the
last sentence of Section 3(b), and then only to such persons as are required to
file reports under Section 16(a) of the Exchange Act (a "Reporting Person").

3.   Eligibility.

     (a) General. Options may be granted to persons who are, at the time of
grant, employees, officers or directors of, or consultants or advisors to, the
Company, Interneuron, or any subsidiaries of the Company as defined in Sections
424(e) and 424(f) of the Code ("Participants") provided, that Incentive Stock
Options may only be granted to individuals who are employees of the Company
(within the meaning of Section 3401(c) of the Code). A person who has been
granted an option may, if he or she is otherwise eligible, be granted additional
options if the Committee shall so determine.

     (b) Grant of Options to Reporting Persons. The selection of a director or
an officer who is a Reporting Person (as the terms "director" and "officer" are
defined for purposes of Rule 16b-3) as a recipient of an option, the timing of
the option grant, the exercise price of the option and the number of shares
subject to the option shall be determined either (i) by the Board of Directors,
(ii) by a committee of the Board of Directors that is composed solely of two or
more Non-Employee Directors having full authority to act in the matter or (iii)
pursuant to provisions for automatic grants set forth in Section 3(c) below. For
the purposes of the Plan, a director shall be deemed to be a "Non-Employee
Director" only if such person is described in Rule 16b-3(b)(3) as interpreted
from time to time.

     (c) Directors' Options. Directors of the Company who are not employees
("Eligible Directors") will receive an option ("Initial Director Option") to
purchase 5,000 shares of Common Stock on the date that such person first becomes
an Eligible Director. As long as an Eligible Director is a member of the Board
of Directors, such Eligible Director will automatically be granted a stock
option ("Automatic Grant") to purchase 3,000 shares of Common Stock on the day
of each annual meeting of stockholders, except for Eligible Directors who
received an Initial Director Option since the most recent Automatic Grant. The
exercise price for each share subject to a Director Option shall be equal to the
fair market value of the Common Stock on the date of grant. Director Options
shall become exercisable in 36 equal monthly installments commencing one month
from the date the option is granted and will expire the earlier of 10 years
after the date of grant or 90 days after the termination of the director's
service on the Board.

4.   Stock Subject to Plan.

     The stock subject to options granted under the Plan shall be shares of
authorized but unissued or reacquired Common Stock. Subject to adjustment as
provided in Section 15 below, the maximum number of shares of Common Stock of
the Company which may be issued



                                       2
<PAGE>



and sold under the Plan is 2,500,000. If an option granted under the Plan shall
expire, terminate or is cancelled for any reason without having been exercised
in full, the unpurchased shares subject to such option shall again be available
for subsequent option grants under the Plan.

5.   Forms of Option Agreements.

     As a condition to the grant of an option under the Plan, each recipient of
an option shall execute an option agreement in such form not inconsistent with
the Plan as may be approved by the Board of Directors. Such option agreements
may differ among recipients.

6.   Purchase Price.

     (a) General. The purchase price per share of stock deliverable upon the
exercise of an option shall be determined by the Board of Directors or the
Committee at the time of grant of such option; provided, however, that in the
case of an Incentive Stock Option, the exercise price shall not be less than
100% of the Fair Market Value (as hereinafter defined) of such stock, at the
time of grant of such option, or less than 110% of such Fair Market Value in the
case of options described in Section 11(b). "Fair Market Value" of a share of
Common Stock of the Company as of a specified date for the purposes of the Plan
shall mean the closing price of a share of the Common Stock on the principal
securities exchange (including the Nasdaq National Market) on which such shares
are traded on the day as of which Fair Market Value is being determined, or on
the next preceding date on which such shares are traded if no shares were traded
on such day, or if the shares are not traded on a securities exchange, Fair
Market Value shall be deemed to be the average of the high bid and low asked
prices of the shares in the over-the-counter market on the day immediately
preceding the date as of which Fair Market Value is being determined or on the
next preceding date on which such high bid and low asked prices were recorded.
If the shares are not publicly traded, Fair Market Value of a share of Common
Stock (including, in the case of any repurchase of shares, any distributions
with respect thereto which would be repurchased with the shares) shall be
determined in good faith by the Board of Directors. In no case shall Fair Market
Value be determined with regard to restrictions other than restrictions which,
by their terms, will never lapse.

     (b) Payment of Purchase Price. Options granted under the Plan may provide
for the payment of the exercise price by delivery of cash or a check to the
order of the Company in an amount equal to the exercise price of such options,
or by any other means which the Board of Directors determines are consistent
with the purpose of the Plan and with applicable laws and regulations
(including, without limitation, the provisions of Rule 16b-3 and Regulation T
promulgated by the Federal Reserve Board).

7.   Option Period.

     Subject to earlier termination as provided in the Plan, each option and all
rights thereunder shall expire on such date as determined by the Board of
Directors or the Committee and set forth in the applicable option agreement,
provided, that such date shall not be later than



                                       3
<PAGE>



(10) ten years after the date on which the option is granted.

8.   Exercise of Options.

     Each option granted under the Plan shall be exercisable either in full or
in installments at such time or times and during such period as shall be set
forth in the option agreement evidencing such option, subject to the provisions
of the Plan. No option granted to a Reporting Person for purposes of the
Exchange Act, however, shall be exercisable during the first six months after
the date of grant. Subject to the requirements in the immediately preceding
sentence, if an option is not at the time of grant immediately exercisable, the
Board of Directors may (i) in the agreement evidencing such option, provide for
the acceleration of the exercise date or dates of the subject option upon the
occurrence of specified events, and/or (ii) at any time prior to the complete
termination of an option, accelerate the exercise date or dates of such option.

9.   Transferability of Options.

     (a) No Incentive Stock Option granted under this Plan shall be assignable
or otherwise transferable by the optionee except by will or by the laws of
descent and distribution or pursuant to a qualified domestic relations order as
defined in the Code or Title I of the Employee Retirement Income Security Act,
or the rules thereunder. An Incentive Stock Option may be exercised during the
lifetime of the optionee only by the optionee.

     (b) Any option granted under the Plan other than an Incentive Stock Option
shall be transferable by the optionee to members of his or her family or
otherwise by will or by the laws of descent and distribution or pursuant to a
qualified domestic relations order as defined in the Code or Title I of the
Employee Retirement Income Security Act, or the rules thereunder. For purposes
of the Plan, an optionee's "family members" shall be deemed to consist of his or
her spouse, parents, children, grandparents, grandchildren and any trusts
created for the benefit of such individuals. A family member to whom an option
has been transferred pursuant to this Section 9(b) shall be hereinafter referred
to as a "Permitted Transferee". An option shall be transferred to a Permitted
Transferee in accordance with the foregoing provisions by the optionee's
execution of an assignment in writing in such form approved by the Board of
Directors or the Committee. The Company shall not be required to recognize the
rights of a Permitted Transferee until such time as it receives a copy of the
assignment from the optionee.

     (c) In the event an optionee dies during his employment by the Company or
any of its subsidiaries, or during the three-month period following the date of
termination of such employment, his options shall thereafter be exercisable,
during the period specified in the option agreement, by his executors,
administrators or Permitted Transferees to the full extent to which such options
were exercisable by the optionee at the time of his death during the periods set
forth in Section 10 or 11(d).



                                       4
<PAGE>



10.  Effect of Termination of Employment or Other Relationship.

     Except as provided in Section 11(d) with respect to Incentive Stock Options
and except as otherwise determined by the Committee at the date of grant of an
option, and subject to the provisions of the Plan, an optionee or his Permitted
Transferee may exercise an option at any time within three (3) months following
the termination of the optionee's employment or other relationship with the
Company or within one (1) year if such termination was due to the death or
disability of the optionee but, except in the case of the optionee's death, in
no event later than the expiration date of the option. If the termination of the
optionee's employment or other relationship with the Company is for cause or is
otherwise attributable to a breach by the optionee of an employment, consulting,
confidentiality or non-disclosure agreement, the option shall expire immediately
upon such termination. The Board or Directors shall have the power to determine
what constitutes a termination for cause or a breach of an employment,
consulting, confidentiality or non-disclosure agreement, whether an optionee has
been terminated for cause or has breached such an agreement, and the date upon
such termination for cause or breach occurs. Any such determinations shall be
final and conclusive and binding upon the optionee.

11.  Incentive Stock Options

     Options granted under the Plan which are intended to be Incentive Stock
Options shall be subject to the following additional terms and conditions:

     (a) Express Designation. All Incentive Stock Options granted under the Plan
shall, at the time of grant, be specifically designated as such in the option
agreement covering such Incentive Stock Options.

     (b) 10% Stockholder. If any employee to whom an Incentive Stock Option is
to be granted under the Plan is, at the time of the grant of such option, the
owner of stock possessing more than 10% of the total combined voting power of
all classes of stock of the Company (after taking into account the attribution
of stock ownership rules of Section 424(d) of the Code), then the following
special provisions shall be applicable to the Incentive Stock Option granted to
such individual:

          (i) The purchase price per share of the Common Stock subject to such
     Incentive Stock Option shall not be less than 110% of the Fair Market Value
     of one share of Common Stock at the time of grant; and

          (ii) the option exercise period shall not exceed five years from the
     date of grant.

     (c) Dollar Limitation. For so long as the Code shall so provide, options
granted to any employee under the Plan (and any other incentive stock option
plans of the Company) which are intended to constitute Incentive Stock Options
shall not constitute Incentive Stock Options to the extent that such options, in
the aggregate, become exercisable for the first



                                       5
<PAGE>



time in any one calendar year for shares of Common Stock with an aggregate Fair
Market Value, as of the respective date or dates of grant, of more than
$100,000.

     (d) Termination of Employment, Death or Disability. No Incentive Stock
Option may be exercised unless, at the time of such exercise, the optionee is,
and has been continuously since the date of grant of his or her option, employed
by the Company, except that:

          (i) an Incentive Stock Option may be exercised within the period of
     three months after the date the optionee ceases to be an employee of the
     Company (or within such lesser period as may be specified in the applicable
     option agreement), provided, that the agreement with respect to such option
     may designate a longer exercise period and that the exercise after such
     three-month period shall be treated as the exercise of a non-statutory
     option under the Plan;

          (ii) if the optionee dies while in the employ of the Company, or
     within three months after the optionee ceases to be such an employee, the
     Incentive Stock Option may be exercised by the person to whom it is
     transferred by will or the laws of descent and distribution within the
     period of one year after the date of death (or within such lesser period as
     may be specified in the applicable option agreement); and

          (iii) if the optionee becomes disabled (within the meaning of Section
     22(e)(3) of the Code or any successor provisions thereto) while in the
     employ of the Company, the Incentive Stock Option may be exercised within
     the period of one year after the date the optionee ceases to be such an
     employee because of such disability (or within such lesser period as may be
     specified in the applicable option agreement).

For all purposes of the Plan and any option granted hereunder, "employment"
shall be defined in accordance with the provisions of Section 1.421-7(h) of the
Income Tax Regulations (or any successor regulations). Notwithstanding the
foregoing provisions, no Incentive Stock Option may be exercised after its
expiration date.

12.  Additional Provisions.

     (a) Additional Option Provisions. The Board of Directors or the Committee
may, in its sole discretion, include additional provisions in option agreements
covering options granted under the Plan, including without limitation
restrictions on transfer, repurchase rights, rights of first refusal,
commitments to pay cash bonuses, to make, arrange for or guaranty loans or to
transfer other property to optionees upon exercise of options, or such other
provisions as shall be determined by the Board of Directors; provided, that such
additional provisions shall not be inconsistent with any other term or condition
of the Plan and such additional provisions shall not cause any Incentive Stock
Option granted under the Plan to fail to qualify as an Incentive Stock Option
within the meaning of Section 422 of the Code.

     (b) Acceleration, Extension, Etc. The Board of Directors may, in its sole



                                       6
<PAGE>



discretion, (i) accelerate the date or dates on which all or any particular
option or options granted under the Plan may be exercised or (ii) extend the
dates during which all, or any particular, option or options granted under the
Plan may be exercised; provided, however, that no such extension shall be
permitted if it would cause the Plan to fail to comply with Section 422 of the
Code or with Rule 16b-3 (if applicable).

13.  General Restrictions.

     (a) Investment Representations. The Company may require any person to whom
an option is granted, as a condition of exercising such option or award, to give
written assurances in substance and form satisfactory to the Company to the
effect that such person is acquiring the Common Stock subject to the option or
award, for his or her own account for investment and not with any present
intention of selling or otherwise distributing the same, and to such other
effects as the Company deems necessary or appropriate in order to comply with
federal and applicable state securities laws, or with covenants or
representations made by the Company in connection with any public offering of
its Common Stock, including any "lock-up" or other restriction on
transferability.

     (b) Compliance With Securities Law. Each option shall be subject to the
requirement that if, at any time, counsel to the Company shall determine that
the listing, registration or qualification of the shares subject to such option
or award upon any securities exchange or automated quotation system or under any
state or federal law, or the consent or approval of any governmental or
regulatory body, or that the disclosure of non-public information or the
satisfaction of any other condition is necessary as a condition of, or in
connection with the issuance or purchase of shares thereunder, such option or
award may not be exercised, in whole or in part, unless such listing,
registration, qualification, consent or approval, or satisfaction of such
condition shall have been effected or obtained on conditions acceptable to the
Board of Directors or the Committee. Nothing herein shall be deemed to require
the Company to apply for or to obtain such listing, registration or
qualification, or to satisfy such condition.

14.  Rights as a Stockholder.

     The holder of an option shall have no rights as a stockholder with respect
to any shares covered by the option (including, without limitation, any rights
to receive dividends or non-cash distributions with respect to such shares)
until the date of issue of a stock certificate to him or her for such shares. No
adjustment shall be made for dividends or other rights for which the record date
is prior to the date such stock certificate is issued.

15.  Adjustment Provisions for Recapitalizations, Reorganizations and Related
     Transactions.

     (a) Recapitalizations and Related Transactions. If, through or as a result
of any recapitalization, reclassification, stock dividend, stock split, reverse
stock split or other



                                       7
<PAGE>



similar transaction, (i) the outstanding shares of Common Stock are increased,
decreased or exchanged for a different number or kind of shares or other
securities of the Company, or (ii) additional shares or new or different shares
or other non-cash assets are distributed with respect to such shares of Common
Stock or other securities, an appropriate and proportionate adjustment shall be
made in (x) the maximum number and kind of shares reserved for issuance under or
otherwise referred to in the Plan, (y) the number and kind of shares or other
securities subject to any then outstanding options under the Plan, and (z) the
price for each share subject to any then outstanding options under the Plan,
without changing the aggregate purchase price as to which such options remain
exercisable. Notwithstanding the foregoing, no adjustment shall be made pursuant
to this Section 15 if such adjustment (i) would cause the Plan to fail to comply
with Section 422 of the Code or with Rule 16b-3 or (ii) would be considered as
the adoption of a new plan requiring stockholder approval.

     (b) Reorganization, Merger and Related Transactions. All outstanding
options under the Plan shall become fully exercisable for a period of sixty (60)
days following the occurrence of any Trigger Event, whether or not such options
are then exercisable under the provisions of the applicable agreements relating
thereto. For purposes of the Plan, a "Trigger Event" is any one of the following
events:

          (i) the date on which shares of Common Stock are first purchased
     pursuant to a tender offer or exchange offer (other than such an offer by
     the Company, any Subsidiary, any employee benefit plan of the Company or of
     any Subsidiary or any entity holding shares or other securities of the
     Company for or pursuant to the terms of such plan), whether or not such
     offer is approved or opposed by the Company and regardless of the number of
     shares purchased pursuant to such offer;

          (ii) the date the Company acquires knowledge that any person or group
     deemed a person under Section 13(d)-3 of the Exchange Act (other than the
     Company, Interneuron, any Subsidiary, any employee benefit plan of the
     Company or of any Subsidiary or any entity holding shares of Common Stock
     or other securities of the Company for or pursuant to the terms of any such
     plan or any individual or entity or group or affiliate thereof which
     acquired its beneficial ownership interest prior to the date the Plan was
     adopted by the Board), in a transaction or series of transactions, has
     become the beneficial owner, directly or indirectly (with beneficial
     ownership determined as provided in Rule 13d-3, or any successor rule,
     under the Exchange Act), of securities of the Company entitling the person
     or group to 30% or more of all votes (without consideration of the rights
     of any class or stock to elect directors by a separate class vote) to which
     all stockholders of the Company would be entitled in the election of the
     Board of Directors were an election held on such date;

          (iii) the date, during any period of two consecutive years, when
     individuals who at the beginning of such period constitute the Board of
     Directors of the Company cease for any reason to constitute at least a
     majority thereof, unless the election, or the nomination for election by
     the stockholders of the Company, of each new director



                                       8
<PAGE>



     was approved by a vote of at least two-thirds of the directors then still
     in office who were directors at the beginning of such period; and

          (iv) the date of approval by the stockholders of the Company of an
     agreement (a "reorganization agreement") providing for:

               (A) The merger or consolidation of the Company with another
          corporation where the stockholders of the Company, immediately prior
          to the merger or consolidation, do not beneficially own, immediately
          after the merger or consolidation, shares of the corporation issuing
          cash or securities in the merger or consolidation entitling such
          stockholders to 80% or more of all votes (without consideration of the
          rights of any class of stock to elect directors by a separate class
          vote) to which all stockholders of such corporation would be entitled
          in the election of directors or where the members of the Board of
          Directors of the Company, immediately prior to the merger or
          consolidation, do not, immediately after the merger or consolidation,
          constitute a majority of the Board of Directors of the corporation
          issuing cash or securities in the merger or consolidation; or

               (B) The sale or other disposition of all or substantially all the
          assets of the Company.

     (c) Board Authority to Make Adjustments. Any adjustments under this Section
15 will be made by the Board of Directors or the Committee, whose determination
as to what adjustments, if any, will be made and the extent thereof will be
final, binding and conclusive. No fractional shares will be issued under the
Plan on account of any such adjustments.

16.  Merger, Consolidation, Asset Sale, Liquidation, Etc.

     (a) General. In the event of any sale, merger, transfer or acquisition of
the Company or substantially all of the assets of the Company in which the
Company is not the surviving corporation, and provided that after the Company
shall have requested the acquiring or succeeding corporation (or an affiliate
thereof), that equivalent options shall be substituted and such successor
corporation shall have refused or failed to assume all options outstanding under
the Plan or issue substantially equivalent options, then any or all outstanding
options under the Plan shall accelerate and become exercisable in full
immediately prior to such event. The Committee will notify holders of options
under the Plan that any such options shall be fully exercisable for a period of
fifteen (15) days from the date of such notice, and the options will terminate
upon expiration of such notice.

     (b) Substitute Options. The Company may grant options under the Plan in
substitution for options held by employees of another corporation who become
employees of the Company, Interneuron, or a subsidiary of the Company,
Interneuron, as the result of a merger or consolidation of the employing
corporation with the Company or a subsidiary of the Company,



                                       9
<PAGE>



Interneuron, or as a result of the acquisition by the Company, Interneuron, or
one of its subsidiaries, of property or stock of the employing corporation. The
Company may direct that substitute options be granted on such terms and
conditions as the Board of Directors considers appropriate in the circumstances.

17.  No Special Employment Rights.

     Nothing contained in the Plan or in any option shall confer upon any
optionee any right with respect to the continuation of his or her employment by
the Company or interfere in any way with the right of the Company at any time to
terminate such employment or to increase or decrease the compensation of the
optionee.

18.  Other Employee Benefits.

     Except as to plans which by their terms include such amounts as
compensation, the amount of any compensation deemed to be received by an
employee as a result of the exercise of an option or the sale of shares received
upon such exercise will not constitute compensation with respect to which any
other employee benefits of such employee are determined, including, without
limitation, benefits under any bonus, pension, profit-sharing, life insurance or
salary continuation plan, except as otherwise specifically determined by the
Board of Directors.

19.  Amendment of the Plan.

     (a) The Board of Directors may at any time, and from time to time, modify
or amend the Plan in any respect; provided, however, that if at any time the
approval of the stockholders of the Company is required under Section 422 of the
Code or any successor provision with respect to Incentive Stock Options, or
under Rule 16b-3, the Board of Directors may not effect such modification or
amendment without such approval; and provided, further, that the provisions of
Section 3(c) hereof shall not be amended more than once every six months, other
than to comport with changes in the Code, the Employer Retirement Income
Security Act of 1974, as amended, or the rules thereunder.

     (b) The modification or amendment of the Plan shall not, without the
consent of an optionee, affect his or her rights under an option previously
granted to him or her. With the consent of the optionee affected, the Board of
Directors or the Committee may amend outstanding option agreements in a manner
not inconsistent with the Plan. The Board of Directors shall have the right to
amend or modify (i) the terms and provisions of the Plan and of any outstanding
Incentive Stock Options granted under the Plan to the extent necessary to
qualify any or all such options for such favorable federal income tax treatment
(including deferral of taxation upon exercise) as may be afforded incentive
stock options under Section 422 of the Code and (ii) the terms and provisions of
the Plan and of any outstanding option to the extent necessary to ensure the
qualification of the Plan under Rule 16b-3.

<PAGE>



20.  Withholding.

     (a) The Company shall have the right to deduct from payments of any kind
otherwise due to the optionee any federal, state or local taxes of any kind
required by law to be withheld with respect to any shares issued upon exercise
of options under the Plan. Subject to the prior approval of the Company, which
may be withheld by the Company in its sole discretion, the optionee may elect to
satisfy such obligations, in whole or in part, (i) by causing the Company to
withhold shares of Common Stock otherwise issuable pursuant to the exercise of
an option or (ii) by delivering to the Company shares of Common Stock already
owned by the optionee. The shares so delivered or withheld shall have a Fair
Market Value equal to such withholding obligation as of the date that the amount
of tax to be withheld is to be determined. An optionee who has made an election
pursuant to this Section 20(a) may only satisfy his or her withholding
obligation with shares of Common Stock which are not subject to any repurchase,
forfeiture, unfulfilled vesting or other similar requirements.

     (b) The acceptance of shares of Common Stock upon exercise of an Incentive
Stock Option shall constitute an agreement by the optionee (i) to notify the
Company if any or all of such shares are disposed of by the optionee within two
years from the date the option was granted or within one year from the date the
shares were issued to the optionee pursuant to the exercise of the option, and
(ii) if required by law, to remit to the Company, at the time of and in the case
of any such disposition, an amount sufficient to satisfy the Company's federal,
state and local withholding tax obligations with respect to such disposition,
whether or not, as to both (i) and (ii), the optionee is in the employ of the
Company at the time of such disposition.

     (c) Notwithstanding the foregoing, in the case of a Reporting Person whose
options have been granted in accordance with the provisions of Section 3(b)
herein, no election to use shares for the payment of withholding taxes shall be
effective unless made in compliance with any applicable requirements of Rule
16b-3.

21.  Cancellation and New Grant of Options, Etc.

     The Board of Directors or the Committee shall have the authority to effect,
at any time and from time to time, with the consent of the affected optionees,
(i) the cancellation of any or all outstanding options under the Plan and the
grant in substitution therefor of new options under the Plan covering the same
or different numbers of shares of Common Stock and having an option exercise
price per share which may be lower or higher than the exercise price per share
of the cancelled options or (ii) the amendment of the terms of any and all
outstanding options under the Plan to provide an option exercise price per share
which is higher or lower than the then-current exercise price per share of such
outstanding options.

22.  Effective Date and Duration of the Plan.

     (a) Effective Date. The Plan shall become effective when adopted by the
Board of Directors, but no Incentive Stock Option granted under the Plan shall
become



                                       11
<PAGE>



exercisable unless and until the Plan shall have been approved by the Company's
stockholders. If such stockholder approval is not obtained within twelve months
after the date of the Board's adoption of the Plan, no options previously
granted under the Plan shall be deemed to be Incentive Stock Options and no
Incentive Stock Options shall be granted thereafter. Amendments to the Plan not
requiring stockholder approval shall become effective when adopted by the Board
of Directors; amendments requiring stockholder approval (as provided in Section
19) shall become effective when adopted by the Board of Directors, but no
Incentive Stock Option granted after the date of such amendment shall become
exercisable (to the extent that such amendment to the Plan was required to
enable the Company to grant such Incentive Stock Option to a particular
optionee) unless and until such amendment shall have been approved by the
Company's stockholders. If such stockholder approval is not obtained within
twelve months of the Board's adoption of such amendment, any Incentive Stock
Options granted on or after the date of such amendment shall terminate to the
extent that such amendment to the Plan was required to enable the Company to
grant such option to a particular optionee. Subject to this limitation, options
may be granted under the Plan at any time after the effective date and before
the date fixed for termination of the Plan.

     (b) Termination. Unless sooner terminated in accordance with Section 16,
the Plan shall terminate upon the earlier of (i) the close of business on the
day next preceding the tenth anniversary of the date of its adoption by the
Board of Directors, or (ii) the date on which all shares available for issuance
under the Plan shall have been issued pursuant to the exercise or cancellation
of options granted under the Plan. If the date of termination is determined
under (i) above, then options outstanding on such date shall continue to have
force and effect in accordance with the provisions of the instruments evidencing
such options.

23.  Governing Law.

     The provisions of this Plan shall be governed and construed in accordance
with the laws of the State of Delaware without regard to the principles of
conflicts of laws.

     Adopted by the Board of Directors on October 31, 1994.

     As amended by the Board of Directors through December 12, 1997.

II.1  Assignment and Assumption. Interneuron hereby assigns to Intercardia all
      of its rights, benefits and interests under each of the Assigned

      or any agreement, commitment or other contractual right thereof,

      thereunder which arise following the Effective Date.

                      EARNED PAYMENT; ROYALTIES AND REPORTS

III.1   Earned Payment and Royalties. In consideration for Interneuron's
        agreements hereunder, Intercardia shall make the following payments to
        Interneuron:

        III.1.1 Earned Payment. Intercardia shall pay the Earned Payment to
                Interneuron on the Closing Date. The Earned Payment shall be
                non-refundable and shall be paid in shares of Intercardia Common
                Stock calculated by dividing $3,000,000 by the Per Share Price.
                The Per Share Price shall equal the Fair Market Value of
                Intercardia Common Stock determined as of the Closing Date;
                provided, however, that if the Fair Market Value of Intercardia
                Common Stock determined as of the Closing Date is (i) less than
                $15.00 then the Per Share Price shall equal $15.00 and (ii) more
                than $29.00, the Per Share Price shall equal $29.00.

        III.1.2 Royalties

                (a)     Subject to the terms and conditions of this Agreement,
                        Intercardia shall pay to Interneuron royalties based on
                        cumulative annual Net Sales of Products by Merck,
                        Intercardia, their Affiliates or sublicensees in the
                        percentages set forth below:

                        Cumulative Annual Net Sales                 Royalty
                        ---------------------------                 -------
                        Less than or equal to $500,000,000              1%
                        Greater than $500,000,000                     1.5%

<PAGE>


                (b)     Royalties at the rates set forth above shall be
                        effective as of the date of First Commercial Sale of a
                        Product and shall continue until Merck, or its successor
                        in interest to the Merck Agreement, no longer has an
                        obligation to pay royalties pursuant to the Merck
                        Agreement, on any Product; provided, however, that
                        payment of royalties shall not be due until cumulative
                        net sales of Products equal $300,000,000 (the "Initial
                        Payment Event").

III.2   Reports; Payment of Royalty; Adjustments.

        (a)     Following the First Commercial Sale of a Product and during the
                term of the Agreement, Intercardia shall furnish to Interneuron
                a copy of the written report received by Intercardia under
                Section 5.5 of the Merck Agreement for each Calendar Quarter of
                a Calendar Year showing the sales of all Products subject to
                royalties sold by Merck, Intercardia, their Affiliates and
                sublicensees during the reporting period (and a reconciliation
                to Net Sales) together with a report showing the royalties
                accrued under this Agreement (collectively, the "Accrual
                Reports"). Accrual Reports shall be due on the thirty-fifth
                (35th) day following the close of each Calendar Quarter.
                Royalties shown to have accrued as of the Initial Payment Event
                shall be due and payable on the thirty-fifth (35th) day
                following the Initial Payment Event. After the Initial Payment
                Event, royalties shown to have accrued by each Accrual Report
                shall be due and payable within ten (10) days after the date
                that the Accrual Report for such Calendar Quarter is due.

                Intercardia shall keep complete and accurate records, including
                copies of any reports forwarded by Merck to Intercardia pursuant
                to the Merck Agreement, in sufficient detail to enable the
                royalties hereunder to be determined. Such Accrual Reports will
                include information in the local currency and as converted into
                United States dollars based on the average exchange rate on the
                first and last day of each month (determined in accordance with
                the Merck Agreement).

        (b)     Royalties shall be paid through the issuance by Intercardia to
                Interneuron of shares (the "Royalty Shares") of Common Stock,
                unless Interneuron and Intercardia agree that royalties may be
                paid in cash. The number of Royalty Shares to be issued shall be
                equal to the amount of royalties due hereunder divided by the
                Fair Market Value determined as of each Accrual Report date.
                Interneuron shall have the registration rights with respect to
                the resale of the Royalty Shares as set forth in a Registration
                Rights Agreement to be entered into as of the Closing Date.

III.3   Audits.

        (a)     Upon the request of Interneuron, Intercardia shall permit an
                independent certified public accounting firm of nationally
                recognized standing selected by Interneuron, to have access
                during normal business hours to such of the records of
                Intercardia as may be reasonably necessary to verify the
                accuracy of the Accrual Reports hereunder for any year ending
                not more than thirty-six (36) months prior to the date of such
                request.

        (b)     If such accounting firm correctly concludes that additional
                royalties were owed during such period, Intercardia shall pay
                the additional royalties within thirty (30) days of the date
                Interneuron delivers to Intercardia such accounting firm's
                written report so concluding. The fees and expenses charged by
                such accounting firm shall be paid by Interneuron; provided,
                however, that if an error in favor of Interneuron in the payment
                of royalties of more than 10% of the royalties due hereunder for
                the period being reviewed is discovered, then the fees and
                expenses of such accounting firm shall be borne by Intercardia.

        (c)     Upon the expiration of thirty-six (36) months following the end
                of any year the calculation of royalties payable with respect to
                such year shall be binding and conclusive upon Interneuron, and
                Intercardia shall be released from any liability or
                accountability with respect to royalties for such year.

III.4   Payment Exchange Rate. All calculations of royalties payable to
        Interneuron under this Agreement shall be made in United States dollars.
        In the case of sales outside the United States, the rate of exchange to
        be used in computing the amount of currency equivalent in United States
        dollars shall be calculated in accordance with Section 5.7 of the Merck
        Agreement.

III.5   Tax Withholding. If laws, rules or regulations require withholding of
        income taxes or other taxes imposed upon payments set forth in this
        Article III, Intercardia shall make such withholding payments as
        required and subtract such withholding payments from the calculation of
        royalties and number of Royalty Shares issuable pursuant to this Article
        III. Intercardia shall submit appropriate proof of payment of the
        withholding taxes to Interneuron within a reasonable period of time.
        Intercardia will use efforts consistent with its usual business
        practices to ensure that any withholding taxes imposed are reduced as
        far as possible under the provisions of the current or any future double
        taxation treaties or agreements between foreign countries, and the
        Parties shall cooperate with each other with respect thereto, with the
        appropriate Party under the circumstance providing the documentation
        required under such treaty or agreement to claim benefits thereunder.

III.6   Representations and Warranties of Interneuron. Interneuron represents
        and warrants to Intercardia that:


                                      -6-
<PAGE>


        (a)     the Royalty Shares payable to Interneuron pursuant to the terms
                hereof will be acquired for investment for its own account,
                without any view to the unregistered public distribution or
                resale thereof, all without prejudice, however, to the right of
                Interneuron at any time lawfully to sell or otherwise to dispose
                of all or any part of the Royalty Shares pursuant to
                registration or any exemption therefrom under the Securities Act
                and applicable state securities laws;

        (b)     Interneuron understands that the Royalty Shares to be received
                by it pursuant to the terms hereof are characterized as
                "restricted securities" under the federal securities laws
                inasmuch as they will be acquired from Intercardia in a
                transaction not involving a public offering and that under such
                laws and applicable regulations such securities may be resold
                without registration under the Securities Act only in certain
                limited circumstances;

        (c)     Interneuron is an "accredited investor" within the meaning of
                Rule 501 of Regulation D under the Securities Act. Interneuron
                has the capacity to evaluate the merits and high risks of an
                investment in the Royalty Shares and is able to bear the
                economic risk of this investment. Interneuron understands that
                an investment in Royalty Shares is highly speculative and
                involves a high degree of risk. Interneuron has been provided
                access to all information requested by it in order to evaluate
                the merits and risks of an investment in the Royalty Shares;

        (d)     Interneuron acknowledges that the certificates evidencing the
                Royalty Shares shall bear a legend substantially as follows:

        "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
        1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR
        HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH
        RESPECT TO THE SECURITIES UNDER SUCH ACT OR AN EXEMPTION FROM
        REGISTRATION UNDER SUCH ACT."

                The foregoing legend shall be removed by Intercardia from any
                certificate at such time as the holder of the Royalty Shares
                represented by the certificate delivers an opinion of counsel
                reasonably satisfactory to Intercardia to the effect that such
                legend is not required in order to establish compliance with any
                provisions of the Securities Act, or at such time as the holder
                of such Royalty Shares satisfies the requirements of Rule 144(k)
                under the Securities Act (provided that Rule 144(k) as then in
                effect does not differ substantially from Rule 144(k) as in
                effect as of the date of this Agreement), and provided further
                that Intercardia has received from the holder a written
                representation that such holder satisfies the requirements of
                Rule 144(k) as then in effect with respect to such Royalty
                Shares;

                rights, (b) as limited by laws relating to the availability of
                specific performance, injunctive relief or other equitable

                Assigned Agreements, except pursuant to the Merck Agreement;

        (h)     to Interneuron's knowledge, there are no claims, judgments or

        (a)     Intercardia is a duly organized and validly existing corporation
                under the laws of the State of Delaware, and has taken all
                required corporate action to authorize the

                the full corporate right, power and authority to enter into this

                execution and delivery of this Agreement and the consummation of

                party, except in each case, for such violations, conflicts or

                assets, results of operations, business or financial condition
                of Intercardia and its subsidiaries, taken as a whole; and
                (assuming this Agreement constitutes the valid and binding
                obligation of Interneuron) upon execution and delivery, this
                Agreement will constitute the legal, valid and binding
                obligation of Intercardia;

        (b)     the Royalty Shares issuable pursuant to this Agreement have been
                duly authorized and, when issued and delivered pursuant to the
                terms of this Agreement will be duly and validly issued, fully

V.1  Assignment. This Agreement shall be binding upon and inure to the benefit
     of the Parties and their respective successors and permitted assigns.

V.2  Severability. In the event that any of the provisions contained in this
     Agreement are held invalid, illegal or unenforceable in any respect, the
     validity, legality and enforceability of the remaining provisions contained

     or to such other address as the Party to whom notice is to be given may
     have furnished to the other Parties in writing in accordance herewith. Any
     such communication shall be deemed to have been given when delivered if
     personally delivered or sent by facsimile on a business day, on the
     business day after patch if sent by nationally-recognized overnight courier
     and on the third business day following the date of mailing if sent by
     mail.

V.4  Applicable Law. The Agreement shall be governed by and construed in
     accordance with the laws of the State of Delaware and the United States
     without reference to any rules of conflict of laws.

V.5  Dispute Resolution. The Parties agree to attempt initially to solve all
     claims, disputes, or controversies arising under, out of, or in connection
     with this Agreement by conducting good faith negotiations. If the Parties
     are unable to settle the matter between themselves, the matter shall

     Whenever a Party shall decide to institute arbitration proceedings, it
     shall give written notice to that effect to the other Party. The Party
     giving such notice shall refrain from instituting the arbitration
     proceedings for a period of sixty (60) days following such notice. During
     such period, the Parties shall make good faith efforts to amicably resolve
     the dispute without arbitration. Any arbitration hereunder shall be
     conducted under the rules of the American Arbitration Association. Each
     such arbitration shall be conducted by a panel of three arbitrators: one
     arbitrator shall be appointed by each of Interneuron and Intercardia and
     the third shall be appointed by the American Arbitration Association. Any
     such arbitration shall be held in Wilmington, Delaware. The arbitrators
     shall have the authority to grant specific performance. Judgment upon the
     award so rendered may be entered in any court having jurisdiction or
     application may be made to such court for judicial acceptance of any award
     and an order of enforcement, as the case may be. In no event shall a demand
     for arbitration be made after the date when institution of a legal or
     equitable proceeding based

     respect to the subject matter hereof. All express or implied agreements and
     understandings, either oral or written, relating to the subject matter
     hereof, heretofore made are expressly merged in and made a part of this
     Agreement. This Agreement may be amended, or any term hereof modified, only
     by a written instrument duly executed by all Parties hereto. To the extent
     this Agreement refers to or incorporates sections of the Merck Agreement,

     amendment or modification of any of such sections of the Merck Agreement.

V.7  No Authority. Except as specifically set forth herein, no Party shall have
     the authority to make any statements, representations or commitments of any
     kind, or to take any action, which shall be binding on any other Party,
     without the prior consent of such other Party.

V.8  Waiver. The waiver by a Party hereto of any right hereunder or the failure
     to perform or of a breach by another Party shall not be deemed a waiver of
     any other right hereunder or of any other breach or failure by said other
     Party whether of a similar nature or otherwise.

     the Territory.

     3.2 Retained Rights. Except as specifically set forth herein, Merck is not
granted any other license by implication or otherwise. During the Research
Program Term and any Extended Research Program Term, Transcell shall retain the
right to use Transcell Intellectual Property and Interneuron shall retain the
right to use Interneuron Intellectual Property (i) in the Field, solely for the
purposes of performing their obligations under the Research Program and (ii)
outside of the Field for any purpose, subject to Section 3.3 below. After
expiration or termination of the Research Program Term, Transcell and
Interneuron shall retain the right to use Transcell Intellectual Property and
Interneuron Intellectual Property outside of the Field for any purpose, subject
to Section 3.3 below.

     3.3 Exclusivity in Expanded Field. In consideration of the Option Payment,
Transcell and Interneuron agree that, for a period of one year from and after
the Effective Date (the "Option Period"), neither Transcell nor Interneuron will
collaborate with a third party in the Expanded Field, or grant or engage in
negotiations to grant a license in the Expanded Field to any third party under
the Transcell and Interneuron Intellectual Property; provided, however, that
Transcell and Interneuron may hold introductory meetings of a general nature
with third parties during such period. During the Option Period, Merck shall
have an exclusive option to request an exclusive license under Transcell
Intellectual Property and

- --------------------------------------------------------------------------------

Interneuron Intellectual Property in the Expanded Field upon terms to be
mutually agreed. In the event that Merck elects to exercise such option, Merck
shall so notify Transcell in writing prior to the end of the Option Period, and
the parties shall negotiate in good faith to complete a mutually acceptable
written license agreement not later than ninety (90) days after the end of the
Option Period. Such agreement will describe the activities to be carried out by
the Parties, the funding arrangements and any additional terms as agreed by the
Parties. Neither Transcell nor Interneuron will collaborate with a third party
in the Expanded Field, or grant or engage in negotiations to grant a license in
the Expanded Field to any third party under the Transcell and Interneuron
Intellectual Property during the period of such negotiations with Merck;
provided, however, that Transcell and Interneuron may hold introductory meetings
of a general nature with third parties during such period.

     3.4 Princeton Agreements. (a) With respect to the 1993 Princeton License
Agreement, Merck acknowledges that it is a sublicensee of Transcell's rights
under such Agreement to the extent provided in Section 3.1 hereof, and Merck
agrees to be bound by the terms thereof to the extent set forth in the Side
Agreement. Except to the extent provided for in the Side Agreement, Merck shall
have no responsibility for payments to Princeton under the 1993 Princeton
License Agreement.

     (b) With respect to the 1997 Princeton Research Agreement, Interneuron
agrees to exercise its right under such Agreement to obtain an exclusive license
to Princeton's interest in Research Information and Inventions in a timely
manner in accordance with the terms of such agreement and to use commercially
reasonable efforts to negotiate a license which is consistent with the terms of
this Agreement and which will provide the broadest possible rights to such
Research Information and Inventions. Interneuron shall promptly provide Merck
with a copy of any such license upon execution thereof, and Merck shall
automatically be deemed a sublicensee of Interneuron's rights thereunder to the
extent provided in Section 3.1 hereof. Except to the extent provided for in the
Side Agreement, Merck shall have no responsibility for payments to Princeton
under the 1997 Princeton Research Agreement and under any license agreement
entered into between Interneuron and Princeton pursuant thereto.

     3.5 Development and Commercialization. Merck shall use reasonable efforts,
consistent with the usual practice followed by Merck in pursuing the
commercialization and marketing of pharmaceutical products of similar market
potential, at its own expense, to develop and commercialize a Licensed Product
on a commercially reasonable basis in such countries in the Territory where in
Merck's opinion it is commercially viable to do so; provided, that such
countries shall include the United States and at least one other Major Market
Country.

                         CONFIDENTIALITY AND PUBLICATION


     4.1 Non-disclosure and Non-Use Obligations. All Proprietary Information
disclosed by one Party to any other Party hereunder shall be maintained in
confidence and shall not be disclosed to any non-party or used for any purpose
except as expressly permitted herein without the prior written consent of the
disclosing Party. The foregoing non-disclosure and non-use obligations shall not
apply to the extent that such Proprietary Information:

          (a)  is known by the receiving Party at the time of its receipt, and
               not through a prior disclosure by the disclosing Party, as
               documented by business records;

          (b)  is properly in the public domain;

          (c)  is subsequently disclosed to a receiving Party by a third party
               who may lawfully do so and is not under an obligation of
               confidentiality to the disclosing Party; or

          (d)  is developed by the receiving Party independently of Proprietary
               Information received from the other Party, as documented by
               research and development records.

     4.2 Permitted Disclosure of Proprietary Information. Notwithstanding
Section 4.1, a Party receiving Proprietary Information of another Party may
disclose such Proprietary Information:

          (a)  to governmental or other regulatory agencies in order to obtain
               patents subject to this Agreement, or to gain approval to conduct
               clinical trials or to market Licensed Product, but such
               disclosure may be only to the extent reasonably necessary to
               obtain such patents or authorizations;

          (b)  by Merck to its permitted sublicensees, agents, consultants,
               Affiliates and/or other third parties for the research and
               development, manufacturing and/or marketing of the Licensed
               Product (or for such parties to determine their interest in
               performing such activities) in accordance with this Agreement on
               the condition that such third parties agree to be bound by the
               confidentiality obligations contained this Agreement, provided
               that the term of confidentiality for such third parties shall be
               no less than seven (7) years; or

          (c)  if required to be disclosed by law or court order, provided that
               notice is promptly delivered to the non-disclosing Party in order
               to provide an

               opportunity to challenge or limit the disclosure obligations;
               provided, however, without limiting any of the foregoing, it is
               understood that (i) any Party hereto, including any Affiliate,
               may make reasonable disclosure of this Agreement, and the terms
               hereof in any filings required by the United States Securities
               and Exchange Commission, subject to review by the other Parties
               of such proposed disclosure and requests for confidential
               treatment for certain provisions of this Agreement, as agreed by
               the Parties.

     4.3 Publication and Public Disclosures. (a) Merck and Transcell each
acknowledge the other Party's interest in publishing its results to obtain
recognition within the scientific community and to advance the state of
scientific knowledge. Each Party also recognizes the mutual interest in
obtaining valid patent protection and in protecting business interests and trade
secret information. Consequently, either Party, its employees or consultants
wishing to make a publication or to make an oral disclosure shall deliver to the
other Party a copy of the proposed written publication or an outline of an oral
disclosure at least forty-five (45) days prior to submission for publication or
presentation. The reviewing Party shall have the right (a) to propose
modifications to the publication or oral disclosure for patent reasons, trade
secret reasons or business reasons or (b) to request a reasonable delay in
publication or oral disclosure in order to protect patentable information. If
the reviewing Party requests a delay, the publishing or disclosing Party shall
delay submission or presentation for a period of sixty (60) days to enable
patent applications protecting each Party's rights in such information to be
filed in accordance with Article VI below. Upon expiration of such sixty (60)
days, the publishing Party shall be free to proceed with the publication or oral
disclosure. If the reviewing Party requests modifications to the publication or
oral disclosure, the publishing Party shall edit such publication to prevent
disclosure of trade secret or proprietary business information prior to
submission of the publication or prior to oral disclosure, subject to the terms
of the Princeton Agreements and the Side Agreement. Interneuron agrees promptly
to forward to Merck for review any proposed publication or other disclosure by
Princeton (including any student thesis or dissertation) received by Interneuron
pursuant to Section 8 of the 1997 Princeton Research Agreement and which is
subject to Merck's rights hereunder and, upon Merck's request, to request that
Princeton delay such publication or presentation for a maximum of 60 days to
protect the patentability of any inventions described therein, subject to the
provisions of the Side Agreement. In addition, upon Merck's request, Interneuron
shall request that such a publication or presentation be altered, or not made,
in order to protect the patentability of any inventions described therein,
subject to Princeton's rights under the 1997 Princeton Research Agreement and
the Side Agreement.

     (b) Any Party hereto, including any Affiliate of a Party, may make
disclosure of the existence of this Agreement and the terms hereof in any
filings required by the United States Securities and Exchange Commission,
provided that any such proposed disclosure shall be submitted to the other
Parties for prior review within a reasonable time in advance of the filing of
such proposed disclosure, and such other Parties may request reasonable
modifications to such proposed disclosure for patent reasons, trade secret
reasons or business reasons. The

- --------------------------------------------------------------------------------

Parties shall use good faith efforts (i) to provide reasonable time for prior
review of proposed disclosures and (ii) to respond to requests for review of
disclosures in a timely manner. A Party which has complied with this Section
shall not be required to delay a disclosure if such delay would cause a
violation of law, regulation or court order. Upon execution of this Agreement,
the Parties may issue a press release in the form attached as Attachment 4.3.
Any additional press releases or public announcements with respect to this
Agreement or the transactions and activities contemplated herein shall be at
such time and in such manner as the Parties shall agree. Any information which
has been previously disclosed pursuant to the terms of this Section 4.3(b) shall
be subject to expedited review by the other Party prior to the subsequent
disclosure of such information. A request for expedited review shall (i) state
the proposed use of the information; (ii) include a copy of the previously
approved disclosure of the information; and (iii) state the deadline for
response.

     achievement of such milestones within a Research Program.

          5.3.2 Fifty percent (50%) of each milestone payment made for the
     achievement of a milestone described in (c), (d) and (e) above shall be
     credited against the royalties payable by Merck under Section 5.4 for the
     Compound for which such milestone was paid.

     5.4 Royalties.

          5.4.1 Royalties Payable By Merck. Subject to the terms and conditions
     of this Agreement, for each Licensed Product Merck shall pay to Transcell
     royalties on a country-by-country basis:

          (a)  if Merck's activities with respect to a Licensed Product or
               Compound would, but for this Agreement, infringe or fall within
               the scope of a Valid Patent Claim or a supplemental protection
               certificate in the country of sale, then:

               (i)  for annual Net Sales of Licensed Products by Merck, its
                    Affiliates or sublicensees less than or equal to [*], an

                    Net Sales in such countries; and

              (iii) for that amount of annual Net Sales of Licensed Products by
                    Merck, its Affiliates or sublicensees greater than [*], an
                    amount equal to [*] percent [*] of such Net Sales in such
                    countries; or

          (b)  for sales other than those covered in Subsection 5.4.1(a) above:

               (i)  for annual Net Sales of Licensed Products by Merck, its
                    Affiliates or sublicensees less than or equal to [*], an

               Royalties on each Licensed Product at the rate set forth above
               shall be effective as of the date of First Commercial Sale of
               Licensed Product in a country and shall continue until either (i)
               the expiration of the last applicable patent on such Licensed
               Product or Compound in such country in the case of sales under
               Subsection 5.4.1(a) above or (ii) until the tenth (10th)
               anniversary of the First Commercial Sale in such country in the
               case of sales of Licensed Product under Subsection 5.4.1(b)
               above, subject to the following conditions:

               (x)  that only one royalty shall be due with respect to the same
                    unit of Licensed Product;

               (y)  that no royalties shall be due upon the sale or other
                    transfer among Merck, its Affiliates or sublicensees, but in
                    such cases the royalty shall be due and calculated upon
                    Merck's or its Affiliate's or its sublicensee's Net Sales to
                    the first independent third party; and

               (z)  no royalties shall accrue on the disposition of Licensed
                    Product in reasonable quantities by Merck, Affiliates or its
                    sublicenses as samples (promotion or otherwise) or as
                    donations (for example, to non-profit institutions or
                    government agencies for a non-commercial purpose).

- --------------------------------------------------------------------------------

          5.4.2 Managed Pharmaceutical Contract. Merck may sell Licensed
     Products to an independent third party (such as a retailer or wholesaler)
     and may subsequently perform services relating to Licensed Products and
     other products under a managed pharmaceutical benefits contract or other
     similar contract. In such cases, it is agreed by the parties that Net Sales
     shall be based on the invoice price to an independent retailer or
     wholesaler, as set forth in the definition of Net Sales in Article I
     hereof, notwithstanding that Merck may receive compensation arising from
     the performance of such services.

          5.4.3 Change in Sales Practices. The parties acknowledge that during
     the term of this Agreement, Merck's sales practices for the marketing and
     distribution of Licensed Products may change to the extent to which the
     calculation of the payment for royalties on Net Sales may become
     impractical or even impossible. In such event the parties agree to meet and
     discuss in good faith new ways of compensating Transcell to the extent
     currently contemplated under Section 5.4.1.

          5.4.4 Royalties for Bulk Compound. In those cases where Merck sells
     bulk Compound rather than a Licensed Product in packaged form to an
     independent third party, and is unable to determine Net Sales, the royalty
     obligations of this Article V shall be applicable to the bulk Compound
     sold.

          5.4.5 Compulsory Licenses. If a compulsory license is granted to a
     Third Party with respect to Licensed Product in any country in the
     Territory with a royalty rate lower than the royalty rate provided by
     Section 5.4.1., then the royalty rate to be paid by Merck on Net Sales in
     that country under Section 5.4.1 shall be reduced to the rate paid by the
     compulsory Third Party licensee.

          5.4.6 Third Party Licenses. If one or more patent licenses from a
     third party or parties are required by Merck, its Affiliates and
     sublicensees in order to develop, make, have made, use, sell or import
     Compound or Licensed Product in a particular country, 50% of any royalties
     actually paid under such third party patent licenses by Merck for sale of
     such Compound or Licensed Product in a country for such Calendar Quarter
     shall be creditable against the royalty payments to be paid to Transcell by
     Merck with respect to the sale of such Licensed Products in such country.

     5.5 Reports; Payment of Royalty. Following the First Commercial Sale of a
Licensed Product and during the term of the Agreement, Merck shall furnish to
Transcell a quarterly written report for the Calendar Quarter showing the sales
of all Licensed Products subject to royalty payments sold by Merck, its
Affiliates and its sublicensees in the Territory during the reporting period
(and a reconciliation to Net Sales) and the royalties payable under this
Agreement. Reports shall be due on the thirtieth (30th) day following the close
of each Calendar Quarter. Royalties shown to have accrued by each royalty report
shall be due and payable on the date such royalty report is due. Merck shall
keep complete and accurate records in sufficient detail to enable the royalties
payable hereunder to be determined.

     5.6 Audits.

     (a) Upon the written request of Transcell and not more than once in each
Calendar Year, Merck shall permit an independent certified public accounting
firm of nationally recognized standing selected by Transcell and reasonably
acceptable to Merck, to have access during normal business hours to such of the
records of Merck as may be reasonably necessary to verify the accuracy of the
royalty reports hereunder for any year ending not more than twenty-four (24)
months prior to the date of such request. The accounting firm shall disclose to
Transcell only whether the royalty reports are correct or incorrect and the
specific details concerning any discrepancies.

     (b) If such accounting firm correctly concludes that additional royalties
were owed during such period, Merck shall pay the additional royalties within
thirty (30) days of the date Transcell delivers to Merck such accounting firm's
written report so correctly concluding. The fees charged by such accounting firm
shall be paid by Transcell; provided, however, that if an error in favor of
Transcell in the payment of royalties of more than five percent (5%) of the
royalties due hereunder for the period being reviewed is discovered, then the
fees and expenses of the accounting firm shall be borne by Merck.

     (c) Merck shall include in each sublicense granted by it pursuant to this
Agreement a provision requiring the sublicensee to make reports to Merck, to
keep and maintain records of sales made pursuant to such sublicense and to grant
access to such records by Transcell's independent accountant to the same extent
required of Merck under this Agreement. Upon the expiration of twenty-four (24)
months following the end of any year, the calculation of royalties payable with
respect to such year shall be binding and conclusive upon Transcell, and Merck
and its sublicensees shall be released from any liability or accountability with
respect to royalties for such year.

     (d) Transcell shall treat all financial information subject to review under
this Section 5.6 or under any sublicense agreement in accordance with the
confidentiality provisions of this Agreement, and shall cause its accounting
firm to enter into an acceptable confidentiality agreement with Merck obligating
it to retain all such financial information in confidence pursuant to such
confidentiality agreement.

     5.7 Payment Exchange Rate. All payments to Transcell under this Agreement
shall be made in United States dollars by bank wire transfer in immediately
available funds to such bank account in the United States designated in writing
by Transcell from time to time. In the case of sales outside the United States,
the rate of exchange to be used in computing the amount of currency equivalent
in United States dollars due Transcell shall be made at the rate of exchange
utilized by Merck in its worldwide accounting system, prevailing on the fourth
to the last business day of the Calendar Quarter to which such payments relate.
Such rate of exchange is that rate quoted by Reuters Ltd. for the spot purchase
of U.S. dollars at 7:15 a.m. Eastern Standard Time on such day.

this Article V, Merck shall make such withholding payments as required and
subtract such withholding payments from the payments set forth in this Article

Interneuron agrees to file, prosecute and maintain in the countries in the
Territory listed on Schedule 7.1 hereto, or such other countries as the Parties

and the Interneuron Patent Assets, respectively, licensed to Merck under this
Agreement; provided, however, (i) with respect to Transcell/Merck Joint
Information and Inventions or Interneuron/Merck Joint Information and
Inventions, Merck shall have the first right to file, prosecute and maintain the
patent applications and (ii) if Transcell or Interneuron elects not to file a

- --------------------------------------------------------------------------------

Interneuron, as the case may be, shall cooperate fully in the filing and
prosecution of such patents. In each case, the filing Party shall give the
non-filing Parties an opportunity to review the text of the application before
filing, shall consult with the non-filing Parties with respect thereto, and
shall supply the non-filing Parties with a copy of the application as filed,
together with notice of its filing date and serial number. Each Party shall keep
the other Parties advised of the status of the actual and prospective patent
filings and upon the request of another Party, provide advance copies of any
papers related to the filing, prosecution and maintenance of such patent
filings. Each Licensor shall promptly give notice to Merck of the grant, lapse,
revocation, surrender, invalidation or abandonment of any Patent licensed or
sub-licensed to Merck by such Licensor. The Party that is the filing Party under
this Section shall be responsible for the payment of all costs and expenses
related to such filing.

     7.2 Right of Other Parties to Prosecute and Maintain Patents. Any Party
having the first right to file, prosecute and maintain the patent applications
and patents referred to in Section 7.1 shall give notice to the other Parties of
any desire to cease prosecution and/or maintenance of a patent constituting part
of Patent Assets and, in such case, shall permit the other Parties, at the other
Parties' sole discretion, to continue prosecution or maintenance at its own
expense, subject to the Princeton Agreements and the Side Agreement.

     7.3 Interference, Opposition, Reexamination and Reissue.

     (a) A Licensor, within ten (10) days of learning of such an event, shall
inform Merck of any request for, or filing or declaration of, any interference,
opposition or reexamination relating to Patent Assets. Merck and such Licensor
thereafter shall consult and cooperate fully to determine a course of action
with respect to any such proceeding and shall agree upon the Parties' rights of
review and approval of submissions relating to such proceeding based upon the
Parties' relative interests in the relevant portion of Patent Assets.

     (b) A Licensor shall not institute any opposition, reexamination, or
reissue proceeding relating to Patent Assets without the prior written consent
of Merck, which consent shall not unreasonably be withheld or delayed.

     (c) In connection with any interference, opposition, reissue, or
reexamination proceeding relating to Patent Assets, Merck and Licensors will
cooperate fully and will provide each other with any information or assistance
that either reasonably may request. Licensors shall keep Merck informed of
developments in any such action or proceeding, including, to the extent
permissible, the status of any settlement negotiations and the terms of any
offer related thereto.

     (d) Licensors shall bear the expense of any interference, opposition,
reexamination, or reissue proceeding relating to Patent Assets.

     7.4 Enforcement and Defense.

     (a) Each Party shall promptly give the other Parties notice of either any
infringement of Patent Assets, or any misappropriation or misuse of Transcell
Know-How or Interneuron Know-How, that comes to such Party's attention. The
Parties shall thereafter consult and cooperate fully to determine a course of
action, including, without limitation, the commencement of legal action by any
or all of the Parties. However, Licensors, upon notice to Merck, shall have the
first right to initiate and prosecute such legal action at their own expense and
in the name of Transcell and/or Interneuron, as applicable, and Merck, or to
control the defense of any declaratory judgment action relating to Transcell and
Interneuron Intellectual Property. Licensors shall promptly inform Merck if both
Licensors elect not to exercise such first right, and Merck thereafter shall
have the right either to initiate and prosecute such action or to control the
defense of such declaratory judgment action in the name of Merck and, if
necessary, Transcell or Interneuron.

     (b) If Licensors elect not to initiate and prosecute an infringement action
as provided in Subsection 7.4(a), and Merck elects to do so, the cost of any
agreed-upon course of action, including the costs of any legal action commenced
or the defense of any declaratory judgment, shall be borne solely by Merck.

     (c) For any such legal action, in the event that any Party is unable to
initiate or prosecute such action solely in its own name, the other Parties will
join such action voluntarily and will execute and cause its Affiliates under its
control to execute all documents necessary for the Party to prosecute and
maintain such action. In connection with any such action, the Parties will
cooperate fully and will provide each other with any information or assistance
that either reasonably may request. Each Party shall keep the other informed of
developments in any such action or proceeding, including, to the extent
permissible by law, the status of any settlement negotiations and the terms of
any offer related thereto.

     (d) Any recovery obtained by Merck or either Licensor shall be shared as
follows:

          (i)  the Party that initiated and prosecuted the action shall recoup
               all of its costs and expenses incurred in connection with the
               action, whether by settlement or otherwise;

          (ii) the other Party then shall, to the extent possible, recover its
               costs and expenses incurred in connection with the action;

         (iii) if Licensors initiated and prosecuted the action, the amount of
               any recovery remaining then shall be retained by Licensors; and

          (iv) if Merck initiated and prosecuted the action, the amount of any
               recovery remaining shall be retained by Merck except that
               Licensors shall receive a portion equivalent to the royalties
               they would have received on such amount.

     (e) Each Licensor shall inform Merck of any certification regarding any
Patent Assets it has received pursuant to either 21 U.S.C. ss.ss.
355(b)(2)(A)(iv) or (j)(2)(A)(vii)(IV) or under Canada's Patented Medicines
(Notice of Compliance) Regulations Article 5 and shall provide Merck with a copy
of such certification within five (5) days of receipt. Licensors' and Merck's
rights with respect to the initiation and prosecution of any legal action as a
result of such certification or any recovery obtained as a result of such legal
action shall be allocated as defined in Subsections 7.4(a) through (d);
provided, however, that Licensors shall exercise the first right to initiate and
prosecute any action and shall inform Merck of such decision within fifteen days
of receipt of the certification, after which time, if Licensors have not advised
Merck of their intention to initiate and prosecute such action, Merck shall have
the right to initiate and prosecute such action.

     7.5 Patent Term Restoration. The Parties shall cooperate in obtaining
patent term restoration or supplemental protection certificates or their
equivalents in any country in the Territory where applicable. If elections with
respect to obtaining such patent term restoration are to be made, Merck shall
have the right to make the election and Licensors shall abide by such election.

     8.2 Termination by Notice. Notwithstanding anything contained herein to the
contrary, Merck shall have the right to terminate this Agreement at any time by
giving ninety (90) days advance written notice to Transcell and Interneuron. In
the event of such termination, (i) the rights and obligations hereunder,
including any payment obligations not due and owing as of the termination date
shall terminate and (ii) Merck shall have no further rights with respect to
Transcell Intellectual Property and Interneuron Intellectual Property.

          8.3.1 Termination for Cause. Any Party may terminate this Agreement by
     notice to the other Parties at any time during the term of this Agreement:

          (a)  if another Party is in breach of its material obligations
               hereunder by causes and reasons within its control and has not
               cured such breach within ninety (90) days after notice requesting
               cure of the breach; or

          (b)  upon the filing or institution of bankruptcy, reorganization,
               liquidation or receivership proceedings, or upon an assignment of
               a substantial portion of the assets for the benefit of creditors
               by another Party; provided, however, in the case of any
               involuntary bankruptcy proceeding such right to terminate shall
               only become effective if the Party consents to the involuntary
               bankruptcy or such proceeding is not dismissed within ninety (90)
               days after the filing thereof.

          8.3.2 Effect of Termination for Cause on License.

          (a)  In the event that either Transcell or Interneuron breaches its
               material obligations hereunder and Merck notifies Transcell and
               Interneuron of the termination of this Agreement under Section
               8.3.1(a) or initiates arbitration against Transcell or
               Interneuron for breach of this Agreement pursuant to Section 9.6,
               or both, any milestone or royalty payments that Merck may be
               required to pay pursuant to this Agreement and that are not
               subject to Section 8.4 shall be paid by Merck instead into an
               escrow account pending the resolution of the arbitration or other
               agreement of the Parties. If the arbitrators determine that Merck
               had the right to terminate this Agreement under Section 8.3.1(a)
               due to a breach of material obligations by Transcell or
               Interneuron which was not cured as set forth therein, Merck's
               licenses pursuant to this Agreement shall become perpetual
               licenses, and the royalty to be paid by Merck, if any, shall be
               determined by the arbitrators. In addition, Licensors shall,
               within one month from such determination, return or cause to be
               returned to Merck all Licensed Products, Compounds, Know-How or
               other substances or composition, delivered or provided by Merck,
               as well as any other materials and/or documents provided by Merck
               in any medium.

          (b)  In the event that Merck breaches its material obligations
               hereunder and Licensors notify Merck of the termination of this
               Agreement under Section 8.3.1(a) or initiate arbitration against
               Merck for breach of this Agreement pursuant to Section 9.6, or
               both, Merck shall continue to pay to Transcell any milestone or
               royalty payments that Merck may be required to pay pursuant to
               this Agreement pending the resolution of the arbitration or other
               agreement of the Parties. If the arbitrators determine that
               Licensors had the right to terminate this Agreement under Section
               8.3.1(a) due to a breach of material obligations by Merck which
               was not cured as set forth therein, Licensors shall be entitled
               to

               any payments then due or owing under this Agreement and Merck
               shall have no further rights with respect to Transcell
               Intellectual Property or Interneuron Intellectual Property. Merck
               shall, within one month from such determination, return or cause
               to be returned to Licensors all Licensed Products, Compounds,
               Know-How or other substances or composition, delivered or
               provided by Licensors, as well as any other materials and/or
               documents provided by Licensors in any medium.

          (c)  In the event Merck terminates this Agreement under Section
               8.3.1(b) or this Agreement is otherwise terminated under
               8.3.1(b), all rights and licenses granted pursuant to this
               Agreement are, and shall otherwise be deemed to be, for purposes
               of Section 365(n) of the Bankruptcy Code, licenses of rights to
               "intellectual property" as defined under Section 101(35A) of the
               Bankruptcy Code. The Parties agree that Merck, as a licensee of
               such rights under this Agreement, shall retain and may fully
               exercise all of its rights and elections under the Bankruptcy
               Code. The Parties further agree that, in the event of the
               commencement of a bankruptcy proceeding by or against Transcell
               or Interneuron under the Bankruptcy Code, Merck shall be entitled
               to a complete duplicate of (or complete access to, as
               appropriate) any such intellectual property and all embodiments
               of such intellectual property upon written request therefore by

communication shall be deemed to have been given when delivered if personally
delivered or sent by telecopier on a business day, on the business day after
dispatch if sent by nationally-recognized overnight courier and on the third
business day following the date of mailing if sent by mail.

     9.5 Applicable Law. The Agreement shall be governed by and construed in
accordance with the laws of the State of New Jersey and the United States
without reference to any rules of conflict of laws or renvoi.

     9.6 Dispute Resolution. The Parties agree to attempt initially to solve all
claims, disputes, or controversies arising under, out of, or in connection with
this Agreement by conducting good faith negotiations. If the Parties are unable
to settle the matter between themselves, the matter shall thereafter be resolved
by alternative dispute resolution, starting with mediation and including, if
necessary, a final and binding arbitration. Whenever a Party shall decide to
institute arbitration proceedings, it shall give written notice to that effect
to the other Party. The Party giving such notice shall refrain from instituting
the arbitration proceedings for a period of sixty (60) days following such
notice. During such period, the Parties shall make good faith efforts to
amicably resolve the dispute without arbitration. Any arbitration hereunder
shall be conducted under the rules of the American Arbitration Association. Each
such arbitration shall be conducted by a panel of three arbitrators: one
arbitrator shall be appointed by each of Merck and Transcell and the third shall
be appointed by the American Arbitration Association. Any such arbitration shall
be held in New York, New York. The arbitrators shall have the authority to grant
specific performance. Judgment upon the award so rendered may be entered in any
court having jurisdiction or application may be made to such court for judicial
acceptance of any award and an order of enforcement, as the case may be. In no
event shall a demand for arbitration be made after the date when institution of
a legal or equitable proceeding based on such claim, dispute or other matter in
question would be barred by the applicable statute of limitations.

     9.7 Entire Agreement. This Agreement and the Side Agreement contain the
entire understanding of the Parties with respect to the subject matter hereof.
All express or implied agreements and understandings, either oral or written,
heretofore made are expressly merged in and made a part of this Agreement. This
Agreement may be amended, or any term hereof modified, only by a written
instrument duly executed by all Parties hereto.

     9.8 Headings. The captions to the several Articles and Sections hereof are
not a part of the Agreement, but are merely guides or labels to assist in
locating and reading the several Articles and Sections hereof.

     9.9 Independent Contractors. It is expressly agreed that the Parties shall
be independent contractors and that the relationship between the Parties shall
not constitute a partnership, joint venture or agency. No Party shall have the
authority to make any statements, representations or commitments of any kind, or
to take any action, which shall be binding on the other Parties, without the
prior consent of such other Parties.

     9.10 Waiver. The waiver by a Party hereto of any right hereunder or the
failure to perform or of a breach by another Party shall not be deemed a waiver
of any other right hereunder or of any other breach or failure by said other
Party whether of a similar nature or otherwise.

     9.11 Counterparts. The Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which

attached to, and made a part of, any sublicense agreement, which shall be
forwarded to PRINCETON upon execution.

     2.3 LICENSEE agrees to forward to PRINCETON annually a copy of such reports
received from any sublicensee as may be pertinent to an accounting of royalties.

     2.4 LICENSEE agrees that Licensed Products leased or sold in the United
States shall be manufactured substantially in the United States.

                                  DUE DILIGENCE

     3.1 LICENSEE shall use its best efforts to commercialize the Licensed
Products and/or Licensed Processes through a thorough, vigorous and diligent
program for exploitation of the Patent Rights.

     3.2 In addition to the obligations of Paragraph 3.1, LICENSEE shall adhere
to the following milestones:

          3.2.1 Within six (6) months from demonstrating the utility of the
     technology described in the Patent Rights by successfully synthesizing two
     complicated oligosaccharides


                                        4
<PAGE>


     on the solid phase such as a derivative of the GMI ganglioside and one
     other biologically important oligosaccharide, LICENSEE shall develop and
     submit to PRINCETON a business plan setting forth the amount of money,
     number and kind of personnel, and time, budgeted and planned for each phase
     of the development of Licensed Products and/or Licensed Processes.

          3.2.2 Within three (3) months of the submission of the business plan,
     LICENSEE shall meet with PRINCETON to discuss further milestones, and
     LICENSEE shall establish further reasonable milestones as soon as
     practicable thereafter.

          3.2.3 Commencing by January 31 following the second anniversary of the
     Effective Date of this License Agreement and by January 31 of each
     succeeding year during which this License agreement has not been
     terminated, LICENSEE shall provide to PRINCETON a written report outlining
     the development plan for the technology for the following year and a brief
     written summary of the developmental activities of the previous year. Such
     report and summary shall include a review of the milestones established
     pursuant to Paragraph 3.2.2 and may include proposed changes thereto based
     on the development activities and other relevant information. LICENSEE
     shall meet with PRINCETON to discuss the report and summary, and LICENSEE
     shall revise the milestones, or establish new ones, as may be appropriate
     following such discussions.

     3.3 LICENSEE's failure to perform in accordance with Paragraph 3.1 shall
constitute a material breach or default for purposes of the termination
provisions of Paragraph 7.3.

     3.4 If LICENSEE fails to meet the milestone set forth in Paragraph 3.2.1 or
any milestones established pursuant to Paragraph 3.2.2 or 3.2.3, PRINCETON and
LICENSEE shall engage in god faith negotiations to establish substitute
milestones, on the basis of the development work that has been completed to
date, the prospectus and expected time and cost for further development,
marketing potential for resulting products, and other relevant factors. Any
material failure by LICENSEE to meet milestones to which it has agreed, except
where such failure was not within LICENSEE's reasonable control, and any failure
by LICENSEE to engage in good faith negotiations relating to milestones, as
provided herein, shall constitute a material breach or default for purposes of
the termination provisions of Paragraph 7.3.

                                    ARTICLE 4

                                    ROYALTIES

     4.1 For the rights, privileges and license granted hereunder, LICENSEE
shall pay to PRINCETON, as set forth below, 


                                       5
<PAGE>


to the end of the term of the Patent Rights or until this License Agreement
shall be terminated as hereinafter provided:

          4.1.1 A license issue fee of fifteen thousand dollars ($15,000), which
     license issue fee shall be deemed earned and due immediately upon the
     execution of this License Agreement.

          4.1.2 A royalty in an amount equal to (a) four percent (4.0%) of Net
     Revenues up to Five Million Dollars ($5,000,000) in any calendar year; and
     (b) a royalty in an amount equal to three percent (3.0%) of Net Revenues
     over Five Million Dollars, but less than Ten Million Dollars ($10,000,000),
     in any calendar year; and (c) a royalty in an amount equal to two percent
     (2.0%) of Net Revenues over Ten Million Dollars ($10,000,000) in any
     calendar year;

          4.1.3 A royalty in an amount equal to (a) fifty percent (50%) of Net
     Ancillary Product Royalties where the royalty rate to LICENSEE is ten
     percent (10%) or more of the sublicensees' sales or revenues; (b) a royalty
     in an amount equal to forty percent (40%) of Net Ancillary Product
     Royalties where the royalty rate to LICENSEE is five percent (5%) or more
     but less than ten percent (10%) of the sublicensees' sales or revenues; and
     (c) a royalty in an amount equal to thirty percent (30%) of Net Ancillary
     Product royalties where the royalty rate to LICENSEE is less than five
     percent (5%) of the sublicensees' sales or revenues.

          4.1.4 Up to fifty percent (50%) of any royalties paid by LICENSEE to a
     third party, in any calendar year, as a condition of utilizing the Licensed
     Patents or the Licensed Processes, may be deducted from the amounts due
     under Paragraphs 4.1.2 and 4.1.3.

          4.1.5 In the event that LICENSEE's royalty payment to PRINCETON
     hereunder for licensed operation during the calendar year 1999, and each
     year thereafter in which this License Agreement is in effect and there are
     any Licensed Products or Licensed Processes, falls below One Hundred
     Thousand Dollars ($100,000), LICENSEE shall, with it last report for said
     years, pay to PRINCETON, in addition to the royalty payments provided in
     the foregoing paragraphs, an amount sufficient to attain such annual
     $100,000 amount.

     4.2 In addition to the foregoing royalties, LICENSEE shall pay to PRINCETON
License Maintenance Fees of Twenty-Five Thousand Dollars ($25,000) for each of
1995 and 1996 and Fifty Thousand Dollars ($50,000) for each of 1997 and 1998.
Such payments will be made with the first quarterly report for each of such
years pursuant to Paragraph 5.2.


                                       6
<PAGE>


     4.3 No multiple royalties shall be payable because the use, lease or sale
of any of the Licensed Products or the practice of the Licensed Processes is, or
shall be, covered by more than one claim contained in the Patent Rights. No
royalties shall be payable under this License Agreement with respect to any Net
Revenues or Net Ancillary Product Royalties if a royalty is also payable thereon
to PRINCETON under the License Agreement between PRINCETON and INTERNEURON
effective as of January 1, 1992.

     4.4 Royalty payments shall be paid in United States dollars at Princeton,
New Jersey or at such other place as PRINCETON may reasonably designate
consistent with the laws and regulations controlling in any foreign country. Any
withholding taxes which LICENSEE shall be required by law to withhold on
remittance of the royalty payments shall be deducted from royalties paid to
PRINCETON. LICENSEE shall furnish PRINCETON with copies of official receipts for
such taxes. If any currency conversion shall be required in connection with the
payment of royalties hereunder, such conversion shall be made by using the
exchange rate at the date of remittance of said payment to LICENSEE.


                                    ARTICLE 5

                               REPORTS AND RECORDS


     5.1 LICENSEE shall keep full, true and accurate books of account containing
all particulars that may be necessary for the purpose of showing the amount
payable to PRINCETON by way of royalty as aforesaid. Said books of account shall
be kept at LICENSEE's principal place of business and shall be maintained in
accordance with generally accepted accounting principles (GAAP). Said books and
the supporting data shall be open, upon reasonable notice to LICENSEE and no
more than twice per calendar year, for five (5) years following the end of the
calendar year to which they pertain, for inspection by the PRINCETON Internal
Audit Division and/or by an independent certified public accountant employed by
PRINCETON, to which LICENSEE has no reasonable objection, for the purpose of
verifying LICENSEE's royalty statement or compliance in other respects with this
License Agreement.

     5.2 LICENSEE, within sixty (60) days after the end of each quarter of each
calendar year, shall deliver to PRINCETON true and accurate reports, giving such
particulars of the business conducted by LICENSEE during the preceding quarter
under this License Agreement as shall be pertinent to a royalty accounting
hereunder. These shall include at least the following:

          (a) All Licensed Products leased or sold, by or for LICENSEE or its
     sublicensees;


                                       7
<PAGE>


          (b) Total amounts received for Licensed Products leased or sold by
     LICENSEE;

          (c) Deductions applicable as provided in the definition of Net

     or more but less than 10%; (ii) 5% or more but less than 10%; and (iii)
     less than 5%;

          (g) Total royalties due to PRINCETON based on Net Ancillary Product
     Royalties of LICENSEE;

          (h) On an annual basis, LICENSEE's annual report.

     5.3 With each such report submitted, LICENSEE shall pay to PRINCETON the
royalties due and payable under this License Agreement provided that no payment
to PRINCETON shall be payable in the event that the remittance of royalties from
foreign countries to the accounts of LICENSEE in the United States shall be
blocked by exchange controls in foreign countries, which exchange controls are
beyond the control of LICENSEE. If no royalties shall be due, LICENSEE shall so
report.


                                    ARTICLE 6

                               PATENT PROSECUTION

     In accordance with Paragraph 11.4 of the Research Agreement, the LICENSEE,
at its own expense and utilizing the Patent Attorneys of its choice, shall have
the sole right and responsibility for the filing, prosecution, and maintenance
of any patent applications and patents contained in the Patent Rights; provided,
however, that PRINCETON shall have the right to approve LICENSEE's choice of
Patent Attorneys, said approval not to be unreasonably withheld. LICENSEE, or
its patent counsel, shall provide PRINCETON with copies of all correspondence
and documents filed with, or received from, the United States Patent and
Trademark Office or any foreign patent office or patent agent. In addition,
LICENSEE agrees that any and all official or "ribbon" copies of issued patents
shall be forwarded to, and retained by, PRINCETON.

                                   TERMINATION

     7.1 If LICENSEE shall become bankrupt or insolvent, or shall file a
petition in bankruptcy, or if the business of LICENSEE shall be placed in the
hands of a receiver, assignee or trustee for the benefit of creditors, whether
by the voluntary act of LICENSEE or otherwise, this License Agreement shall
automatically terminate.

     7.2 Should LICENSEE fail in its payment to PRINCETON of royalties due in
accordance with the terms of this License Agreement, PRINCETON shall have the
right to serve notice upon LICENSEE, by certified mail to the address designated
in Article 14 hereof, of its intention to terminate this License Agreement
within thirty (30) days after receipt of said notice of termination unless
LICENSEE shall pay to PRINCETON, within the thirty (30) day period, all such
royalties due and payable. Upon the expiration of the thirty (30) day period, if
LICENSEE shall not have paid all such royalties due and payable, the right,
privileges and license granted hereunder shall thereupon immediately terminate.

     7.3 Upon any material breach or default of this License Agreement by
LICENSEE, other than those occurrences set out in Paragraphs 7.1 and 7.2
hereinabove, which shall always take precedence in that order over any material
breach or default referred to in this Paragraph 7.3, PRINCETON shall have the
right to terminate this License Agreement and the rights, privileges and license
granted hereunder by ninety (90) days' notice to LICENSEE by certified mail to
the address designated in Article 14 hereof. Such termination shall become
effective unless LICENSEE shall have cured any such breach or default prior to
the expiration of the ninety (90) day period from receipt of the notice of
termination.

     7.4 LICENSEE shall have the right to terminate this License Agreement at
any time on six (6) months' notice by certified mail to PRINCETON, in whole or
with respect to designated countries or designated Patent Rights, Licensed
Products or Licensed Processes.

     7.5 Upon termination of this License Agreement for any reason, nothing
herein shall be construed to release either party from any obligation that
matured prior to the effective date of such termination. LICENSEE and/or any
sublicensee thereof may, however, after the effective date of such termination,
sell all Licensed Products, and complete Licensed Products in the process of
manufacture at the time of such termination, and sell the 


                                       9
<PAGE>


same, provided that LICENSEE shall pay to PRINCETON the royalties thereon as
required by Article 4 of this License Agreement and shall submit the reports
required by Article 5 hereof on the sales of Licensed Products.

                                   ARBITRATION

     8.1 Except as to issues relating to the validity, enforceability, or
infringement of any patent contained in the Patent Rights licensed hereunder,
any and all claims, disputes or controversies arising under, out of, or in
connection with this License Agreement, which have not been resolved by good
faith negotiations between the parties, shall be resolved by final and binding
arbitration in Princeton, New Jersey under the rules of the American Arbitration
Association then in effect. The arbitrators shall have no power to add to,
subtract from, or modify any of the terms or conditions of this License
Agreement. Any award rendered in such arbitration may be enforced by either
party in either the state or federal courts of New Jersey, to whose jurisdiction
for such purposes, PRINCETON and LICENSEE each hereby irrevocably consents and
submits.

     8.2 Any claim, dispute, or controversy concerning the validity,
enforceability, or infringement of any patent contained in the Patent Rights
licensed hereunder shall be resolved in any court having jurisdiction thereof.

     8.3 In the event that, in any arbitration proceeding, any issue shall arise
concerning the validity, enforceability, or infringement of any patent contained
in the Patent Rights licensed hereunder, the arbitrators shall, to the extent
possible, resolve all issues other than validity, enforceability, and
infringement; in any event, the arbitrators shall not delay the arbitration
proceeding for the purpose of obtaining or permitting either party to obtain
judicial resolution of such issues, unless an order staying the arbitration
proceeding shall be entered by a court of competent jurisdiction. Neither party
shall raise any issue concerning the validity, enforceability, or infringement
of any patent contained in the Patent Rights licensed hereunder, in any
proceeding to enforce any arbitration award hereunder, or in any proceeding
otherwise arising out of any such arbitration award.

                         INFRINGEMENT AND OTHER ACTIONS

     9.1 LICENSEE and PRINCETON shall promptly provide written notice, to the
other party, of any alleged infringement by a third party of the Patent Rights
and provide such other party with any available evidence of such infringement.

     9.2 During the term of this Agreement, LICENSEE shall have the right, but
not the obligation, to prosecute and/or defend, at its own expense and utilizing
counsel of its choice, any infringement of, and/or challenge to, the Patent
Rights. In furtherance of such right, PRINCETON hereby agrees that LICENSEE may
join PRINCETON as a party in any such suit, without expense to PRINCETON. No
settlement, consent judgment or other voluntary final disposition of any such
suit may be entered into without the consent of PRINCETON, which consent shall
not unreasonably be withheld. LICENSEE shall indemnify PRINCETON against any
order for costs that may be made against PRINCETON in any such suit.

     9.3 In the event that LICENSEE shall undertake the enforcement and/or
defense of the Patent Rights, as provided in Paragraph 9.2, LICENSEE may
withhold up to fifty percent (50%) of the royalties otherwise thereafter due
PRINCETON and apply the same toward reimbursement of its expenses, including
attorneys' fees, in connection therewith. Any recovery of damages by LICENSEE,
in any such suit, shall be applied first in satisfaction of any unreimbursed
expenses and legal fees of LICENSEE relating to the suit, and next toward
reimbursement of PRINCETON for any royalties past due or withheld and applied
pursuant to this paragraph. The balance remaining from any such recovery shall
be divided equally between LICENSEE and PRINCETON.

     9.4 If within six (6) months after receiving notice of any alleged
infringement, LICENSEE shall have been unsuccessful in persuading the alleged
infringer to desist, or shall not have brought and shall not be diligently
prosecuting an infringement action, or if LICENSEE shall notify PRINCETON, at
any time prior thereto, of its intention not to bring suit against the alleged
infringer, then, and in those events only, PRINCETON shall have the right, but
not the obligation, to prosecute, at its own expense and utilizing counsel of
its choice, any infringement of the Patent Rights, and PRINCETON may, for such
purposes, join the LICENSEE as a party plaintiff. The total cost of any such
infringement action commenced solely by PRINCETON shall be borne by PRINCETON
and PRINCETON shall keep any recovery or damages for past infringement derived
therefrom.

     9.5 In any suit to enforce and/or defend the Patent Rights pursuant to this
License Agreement, the party not in control of such suit shall, at the request
and expense of the controlling 


                                       11
<PAGE>


party, cooperate in all respects and, to the extent possible, have its employees
testify when requested and make available relevant records, papers, information,
samples, specimens and the like.


                                   ARTICLE 10

                                PRODUCT LIABILITY

     10.1 PRINCETON, by this License Agreement, makes no representation as to
the patentability and/or breadth of the inventions contained in the Patent
Rights. PRINCETON by this License Agreement makes no representation as to
patents now held or which will be held by others in the field of the Licensed
Products or Licensed Process for a particular purpose.

     10.2 LICENSEE agrees to defend, indemnify, and hold PRINCETON harmless from
and against all liability, demands, damages, expense or losses for death,
personal injury, illness or property damage arising (a) out of use by LICENSEE
or its transferees of inventions licensed or information furnished under this
License Agreement, or (b) out of any use, sale or other disposition by LICENSEE
or its transferees of products made by use of such inventions or information. As
used in this clause, "PRINCETON" includes its Trustees, Officers, Agents,
Employees and Students and "LICENSEE" includes its Affiliates, Contractors and
Sub-Contractors.

     10.3 In discharge of the above, LICENSEE will maintain general liability
insurance in the amount of at least One Million Dollars ($1,000,000) per
occurrence, with an appropriate deductible, if possible of not more than $10,000
per occurrence, with such insurers and on such terms as PRINCETON approves in
writing, against damage to, or destruction of, property, and injury to, or death
of, individuals, and against such other risks as PRINCETON may reasonably
request arising out of, or in connection with, any of the Licensed Products or
Licensed Process. PRINCETON, and its officers, trustees, and employees will be
named insureds under all such insurance. Such insurance will also provide that
PRINCETON will be given notice of any modification thereof and at least ten (10)
days prior written notice of cancellation or termination and the reason
therefor. LICENSEE will furnish PRINCETON, upon request, written confirmation
issued by the insurer or an independent insurance agent confirming that
insurance is maintained in accordance with the above requirements.

                                   ASSIGNMENT

     11.1 LICENSEE may assign or otherwise transfer this License Agreement and
the license granted hereunder and the rights acquired by it hereunder so long as
such assignment or transfer shall be to a subsidiary or shall be accompanied by
a sale or other transfer of LICENSEE's entire business or that part of
LICENSEE's business to which the license granted hereunder relates.

     11.2 LICENSEE shall give PRINCETON thirty (30) days prior written notice
within which to approve, or reasonably object to, such assignment or transfer.
If within thirty (30) days after the giving of such notice, no written objection
is received by LICENSEE, PRINCETON shall be deemed to have approved such
assignment or transfer; provided, however, PRINCETON shall not be deemed to have
approved such assignment or transfer unless such assignee or transferee shall
have agreed in writing to be bound by the terms and conditions of this License
Agreement. Upon such assignment or transfer and agreement by such assignee or
transferee, the term LICENSEE, as used herein, shall mean such assignee or
transferee. If LICENSEE shall sell or otherwise transfer its entire business or
that part of its business to which the license granted hereby relates and the
transferee shall not have agreed in writing to be bound by the terms and
conditions of this License Agreement, or new terms and conditions shall not have
agreed in writing to be bound by the terms and conditions of this License
Agreement, or new terms and conditions shall not have been reasonably agreed
upon within sixty (60) days of such sale or transfer, PRINCETON shall have the
right to terminate this License Agreement.

                                NON-USE OF NAMES

     LICENSEE shall not use the name of PRINCETON or any adaptation thereof or
of any faculty member, employee or student, in any advertising, promotional or
sales literature without prior written consent obtained from PRINCETON, in each
case, except that LICENSEE may state that it is licensed by PRINCETON, under one
or more of the patents and/or applications comprising the Patent Rights.

                                 EXPORT CONTROLS

     It is understood that PRINCETON is subject to United States laws and
regulations controlling the export of technical data, computer software,
laboratory prototypes and other commodities (including the Arms Export Control
Act, as amended, and the Export Administration Act of 1979), and that its
obligations hereunder are contingent on compliance with applicable United States
export laws and regulations. The transfer of certain technical data and
commodities may require a license from the cognizant agency of the United States
Government and/or written assurances by LICENSEE that LICENSEE shall not export
data or commodities to certain foreign countries without prior approval of such
agency. Princeton neither represents that a license shall not be required nor
that, if required, it shall be issued.

     15.1 This License Agreement shall be construed, governed, interpreted and
applied in accordance with the laws of the State of New Jersey, except that
questions affecting the validity, enforceability, or infringement of any patent
contained in the Patent Rights shall be determined by the law of the country in
which the patent was granted.

     15.3 The provisions of this License Agreement are severable, and in the
event that any provision of this License Agreement shall be determined to be
invalid or unenforceable under any controlling body of law, such invalidity or
unenforceability shall not in any way affect the validity or enforceability of
the remaining provisions hereof.

     15.4 LICENSEE agrees to mark the Licensed Products sold in the United
States with all applicable United States patent numbers. All Licensed Products

130-M173, seeking $195,154 for the period July 1, 1993 to December 31, 1993. The
proposed Sponsored Research is an extension of the Research Agreement between
the University and Transcell dated July 1, 1991.

Pursuant to the Research Agreement, Transcell is providing this written notice
of its decision to provide the requested funding. Although the Research Proposal
did not include a payment schedule, we propose to adapt the schedule set forth

     Amendment No. 1 (the "Amendment") to License Agreement, effective as of
February 21, 1997, is by and between The Trustees of PRINCETON UNIVERSITY, a
nonprofit, private educational institution existing in the State of New Jersey
(hereinafter referred to as "PRINCETON"), and TRANSCELL TECHNOLOGIES, INC., a
corporation duly organized and existing under the laws of the State of Delaware
and having a principal place of business at 2000 Cornwall Road, Monmouth
Junction, New Jersey 08852 (hereinafter referred to as the "LICENSEE").

     WHEREAS, PRINCETON and LICENSEE entered into a License Agreement effective
as of October 14, 1993 (the "License Agreement"), granting LICENSEE a worldwide
license, with the right to sublicense, under certain inventions and confidential
information, including any patent rights which may be obtained thereon, on the
terms and conditions set forth therein; and

     WHEREAS, PRINCETON and LICENSEE desire to amend certain provisions of the
License Agreement, on the terms and conditions set forth herein.

     NOW, THEREFORE, it is agreed as follows:

     1. Section 1.5(b) of the License Agreement is hereby amended to add the
following new subsection (iv) to the end thereof:

          "(iv) been developed using technology covered under the Patent Rights,
          on which technology LICENSEE had expended $1,000,000 or more in
          development costs"

     2.   Article 2 of the License Agreement is hereby amended to add the
          following new Section 2.5 to the end thereof:

          "2.5 Notwithstanding the provisions set forth in the preceding
          sections of this Article 2, PRINCETON reserves the right to use the
          invention, PRINCETON'S Patent Rights, the Licensed Products, the
          Licensed Processes, the technology, associated information and
          know-how for PRINCETON'S own internal educational, research and other
          non-commercial purposes only, and to publish the results thereof in
          accordance with the terms of Section 13 of the Research Agreement."

     3.   Section 4.1 of the License Agreement is hereby amended to add the
          following new Section 4.1.6 to the end thereof:

          "4.1.6 Notwithstanding the provisions set forth in the preceding
          sections of this Section 4.1, in the event of a sublicense of Patent
          Rights, the maximum royalty payable hereunder shall be 25% of the
          royalties received by LICENSEE from sublicensees as a result of
          sublicensees' sales of Licensed Products and Licensed 

<PAGE>


          Processes; provided, however, that in the event such limitation would
          cause royalties payable hereunder to be less than 1.5% of the
          sublicensees' net sales, then the royalty payable hereunder shall be
          1.5% of the sublicensees' net sales. For example, in the event the
          royalty payable from a sublicensee to LICENSEE is 5% of the
          sublicensee's net sales of Licensed Products and Licensed Processes,
          the royalties payable to PRINCETON hereunder shall be 1.5% (since 25%
          of 5% is less than 1.5%). For purposes of this section, references to
          sublicensees' net sales assume that such net sales are calculated in
          the same manner as Net Sales in this Agreement."

     4.   Section 4.2 is hereby amended and restated in its entirety to read as
          follows:

          "4.2 In addition to the foregoing royalties, LICENSEE shall pay to
          Princeton License Maintenance Fees of (i) two hundred thousand dollars
          ($200,000), payable upon execution of this Amendment and (ii) one
          hundred thousand dollars ($100,000) for each year commencing October
          14, 1997, through the earlier of (i) termination of the License
          Agreement or (ii) the date of first commercial sale of a Licensed
          Product."

     5.   Appendix II to the License Agreement is hereby updated and restated as
          of the date of this Amendment in the form attached hereto.

     6.   This Amendment may be executed in counterparts, each of which
          counterparts, when so executed and delivered, shall be deemed an
          original and all of which counterparts, taken together, shall
          constitute one and the same instrument. Unless separately defined, all
          defined terms herein shall have the meaning set forth in the License
          Agreement.

     IN WITNESS WHEREOF, the parties hereto have executed this Amendment, in
duplicate, by proper persons thereunto duly authorized.

                              PRINCETON UNIVERSITY
                               RESEARCH AGREEMENT


This Research Agreement is entered into on April 29, 1997 between the Trustees
of Princeton University, a not-for-profit, private educational institution
existing in the State of New Jersey, hereinafter referred to as "Princeton" and
Interneuron Pharmaceuticals Inc., a corporation existing under the laws of the
State of Delaware, hereinafter referred to as "Sponsor."

1.   Statement of Work

     Princeton, through the Department of Chemistry, has valuable experience,
     skill and ability in the construction of a [*] library. Sponsor desires to
     have Princeton undertake a research project in the above-named area in
     accordance with the scope of work described in Exhibit A, Research
     Proposal. Princeton agrees to use reasonable effort to perform the research
     project described therein and hereafter referred to as the "Research."
     Sponsor acknowledges that Princeton makes no expressed or implied
     warranties for the research.

2.   Principal Investigator

     The research will be supervised by Professor Daniel Kahne. If for any
     reason he is unable to continue to serve as Principal Investigator and a
     successor acceptable to both Princeton and Sponsor is not available, this
     Agreement shall be terminated as provided in Article 6.

3.   Period of Performance

     This research will be conducted during the period July 1, 1996 through June
     30, 1998, but may be extended under the same terms and conditions by mutual
     written agreement of the Parties. A third year of optional funding is
     listed in the budget and shall be exercised by mutual agreement of the
     parties.

4.   Reimbursement of Costs

     Princeton shall be reimbursed by Sponsor for all costs incurred in
     connection with the research up to the amount of $441,246. While it is
     estimated that this amount is sufficient to conduct the research, Princeton
     and Sponsor may mutually agree to fund the third year of research, as
     listed in the budget. Sponsor is not liable for any cost in excess of the
     amount specified herein unless this Agreement is modified in writing by
     both parties.

          Princeton University
          Princeton, New Jersey  08544

6.   Termination

     Performance under this Agreement may be terminated by Sponsor upon sixty
     (60) days' written notice; performance may be terminated by Princeton if
     circumstances beyond its control preclude continuation of the research.
     Upon termination, Princeton will be reimbursed for all costs and
     non-cancelable commitments incurred in the performance of the research and
     not yet paid for, such reimbursement together with other payments not to
     exceed the total estimated project costs specified in Article 4. The
     provision of Article 7 hereof shall survive any termination of this
     Agreement.

7.   Intellectual Property

     (a)  Ownership of Inventions

          (1)  The term "Invention" means any patentable or potentially
               patentable subject matter or discovery conceived or reduced to
               practice in carrying out of the Research pursuant to this
               Agreement.

          (2)  Any Invention developed, as part of this Research, solely by
               Sponsor personnel will be the exclusive property of Sponsor which
               may, to the extent permitted by law, hold all right, title and
               interest in such Invention. Such Inventions, including the right,
               title and interest therein, are referred to herein as
               "Sponsor-owned".

          (3)  Any Invention developed, as part of the Research, solely by
               Princeton personnel, including faculty, students and employees,
               will be the exclusive property of Princeton, which may, to the
               extent permitted by law, hold all right, title, and 


                                       2
<PAGE>


               interest in such Invention. Such Inventions, including the right,
               title and interest therein, are referred to herein as
               "Princeton-owned".

          (4)  Any Invention developed, as part of this Research, jointly by
               Sponsor and Princeton personnel, including faculty, students and
               employees, will be the mutual property of both parties, which
               may, to the extent permitted by law, jointly hold all right,
               title and interest in such Invention. Such Inventions, including
               the right, title and interest therein, are referred to herein as
               "Jointly-owned".

     (b)  Patents

          The parties agree that it is desirable to file patent applications on
          discoveries and Inventions conceived or first reduced to practice
          during the term of this Agreement. Sponsor acknowledges that Princeton
          has an obligation to protect and transfer its technology for the
          public benefit and the parties agree to cooperate to effect that end
          in an expedient manner equitable to both parties.

     (c)  Patent Applications

          (1)  Princeton and Sponsor agree to cooperate fully in applying for,
               obtaining, prosecuting and maintaining patents.

          (2)  Princeton shall promptly disclose to Sponsor, in writing, any
               Princeton-owned or Jointly-owned Inventions disclosed to
               Princeton. Princeton shall file and prosecute U.S. and foreign
               patent applications in its name at Sponsor's request and expense,
               using mutually agreed upon patent counsel, on such
               Princeton-owned or Jointly-owned Inventions as may, in Sponsor's
               judgment, become appropriate during the term of this Agreement
               and up to twelve (12) months after its termination. All
               information given to Sponsor by Princeton in accordance with this
               section shall be held in confidence by Sponsor so long as such
               information remains unpublished or undisclosed by Princeton. Such
               patent applications and any patents resulting therefrom shall be
               subject to the terms of this Agreement.

          (3)  Princeton shall have the opportunity to file patent applications
               in its name at its own expense for those Princeton-owned or
               Jointly-owned Inventions made by its personnel and for which
               Sponsor does not agree, within thirty (30) days after
               notification by Princeton of its intent to file a patent
               application, to pay for Princeton to file said patent
               application; such patent applications and any patents resulting
               therefrom shall not be subject to the terms of this Agreement.

          (4)  Sponsor patent counsel may prepare, file and prosecute all U.S.
               applications for any Jointly-owned Inventions, at Sponsor's sole
               cost and expense, provided, however, that Princeton shall have
               the right to review and approve the application, and be consulted
               on all prosecution actions, and foreign filing decisions.
               Princeton's right,


                                       3
<PAGE>


               title and interest in the Jointly-owned Inventions disclosed or
               claimed in such patent applications or in any such patents shall
               be subject to the terms of this Agreement.

     (d)  Grant of Patent Rights

          (1)  In consideration for its sponsorship of the research program,
               Sponsor shall retain an irrevocable, royalty-free, worldwide,
               nonexclusive license, without the right to sublicense, for
               Sponsor's own internal research use, under any Princeton-owned
               Inventions, under any patents or patent applications.

          (2)  Princeton, to the extent it is permitted to do so by its
               agreements with other government sponsors of research, and the
               provisions of Public Laws 96-517 and 98-620, grants to Sponsor an
               exclusive Option to obtain an exclusive worldwide license to any
               Princeton-owned Inventions and Princeton's right, title and
               interest under any Jointly-owned Inventions, patents or patent
               applications, with a right to sublicense upon Princeton's
               approval, which shall not be unreasonably withheld, on the terms
               and conditions set forth in the resulting license agreements.
               Sponsor agrees not to sublicense or assign any such intellectual
               property to Transcell Technologies Inc., without Princeton's
               written consent.

          (3)  Such Option with respect to each Invention shall extend for a
               period commencing on the date the Invention is disclosed to
               Sponsor through ninety (90) days from the filing date of a patent
               application disclosing and claiming same. Sponsor may exercise
               its Option on Princeton-owned and jointly-owned patent
               applications or patents by providing a written statement to
               Princeton. Upon exercise of each such Option, Sponsor and
               Princeton shall have twelve (12) months to negotiate in good
               faith a royalty-bearing worldwide exclusive license under
               reasonable royalty terms. During the Option and subsequent
               negotiation periods, Princeton shall not offer commercial license
               rights to any third party. At the end of twelve (12) months from
               the date Sponsor exercises its Option if no license agreement has
               been signed, Princeton shall be free to negotiate licenses with
               other parties, and Sponsor shall have no further rights to such
               Inventions except for those provided for in 7.d.1 herein, and
               those it retains to any jointly owned Inventions by virtue of its
               ownership thereof.

     (e)  Unpatented Technology

          It is recognized that some technology created in the performance of
          the Research and uses thereof may not be protected by patent
          applications or patents. Accordingly, Princeton, to the extent
          permitted by its obligations to other government sponsors, hereby
          grants to Sponsor the exclusive Option to negotiate an exclusive
          royalty-bearing worldwide license to use any such technology for
          commercial purposes, to the extent said technology or the use thereof
          contemplated by Sponsor is not covered by a patent application or
          patent assigned to or controlled by Princeton. Sponsor may exercise
          this 


                                       4
<PAGE>


          Option in the same manner as, and subject to the limitations of, its
          Options under Inventions, patent application or patents with the
          Option period beginning upon the provision of a written description or
          samples of the technology to Sponsor. Princeton hereby grants to
          Sponsor a worldwide, royalty-free, nonexclusive license, without the
          right to sublicense, to utilize all such technology for its own
          internal research purposes only.

     (f)  Computer Software

          Copyrights and all other rights in any computer software created in
          the course of the Research shall be owned by Princeton. Sponsor shall
          have nonexclusive royalty-free license for internal use, without the
          right to sublicense. Princeton hereby grants Sponsor an exclusive
          Option to negotiate an exclusive royalty-bearing license, such Option
          to extend for sixty (60) days from the date Sponsor is provided with a
          copy of said software. Sponsor may exercise this Option in the same
          manner as, and subject to the limitations of, its Option under patent
          applications or patents.

8.   Publication

     (a)  Subject to the terms of this paragraph 8, Princeton shall have the
          right, at its discretion, to release information or to publish any
          material resulting from the Research. Sponsor and Princeton
          acknowledge that patent rights may be jeopardized by public disclosure
          of such Research results prior to the filing of a patent application.
          Accordingly, Princeton shall forward copies of presentations and
          publications (including poster sessions) to Sponsor for review and
          comment 30 days prior to submission for publication. Sponsor may
          request Princeton to delay publication an additional sixty days (60)
          days in order to protect the potential patentability of any Invention
          described therein. Such delay shall not, however, be imposed on the
          filing of any student thesis or dissertation.

     (b)  The parties will cooperate to minimize delay of manuscripts. In no
          event will a submission for publication or presentation under this
          Agreement be delayed longer than three (3) months from the date a
          manuscript is submitted to Sponsor for review.

     (c)  Princeton shall give Sponsor the option of receiving an acknowledgment
          in any publication for its sponsorship of the Research. Sponsor
          understands that the basic objective of research activities at
          Princeton is the generation of new knowledge and its expeditious
          dissemination. Therefore, in review of any publication, Sponsor shall
          provide all reasonable cooperation in meeting this objective.

9.   Consultation

     Selected personnel of Sponsor, designated by Sponsor to Princeton, shall
     have the right to confer with the Principal Investigator and his or her
     associates for such reasonable periods and at such times as are mutually
     agreeable.

10.  Publicity and Use of Names

     Neither Sponsor nor Princeton will use the name of the other in connection
     with any product, promotional literature, or advertising material without
     the prior written permission of the other party. This shall not include
     internal documents available to the public that identify the existence of
     the Agreement; and shall not preclude the Sponsor from disclosing any
     information to the SEC or other governmental regulatory agency, if required

11.  Reports

     Princeton shall furnish Sponsor annual letter reports during the term of
     this Agreement summarizing the research conducted. A final report setting
     forth the accomplishments and significant research findings shall be
     prepared by Princeton and submitted to Sponsor within ninety (90) days of
     the expiration of the Agreement. A final summary report shall be submitted
     to Sponsor if the Research is extended for an additional year, under the
     terms of Article 3.

12.  Proprietary Data

     Princeton's acceptance and use of any proprietary data which may be
     supplied by Sponsor in the course of the Research shall be subject to the
     following:

     (a)  The data must be marked or designated in writing as proprietary to
          Sponsor.

     (b   Princeton retains the right to refuse to accept any such data which it
          does not consider to be essential to the completion of the Research.

     (c)  When Princeton does accept such data as proprietary, it agrees to
          exercise all reasonable efforts not to publish or otherwise reveal the
          data to others outside the University without the permission of
          Sponsor, unless the data has already been published or disclosed
          publicly by third parties or is required to be disclosed by order of a
          court of law.

     (d)  Princeton understands and agrees that the disclosure of proprietary
          data or confidential information to the University by the Sponsor
          shall not be construed as granting Princeton any ownership rights in,
          or to, the disclosed data or information, or any right to use such
          data or information, except in the manner agreed upon by the Sponsor
          and Princeton prior to disclosure of the proprietary data or
          confidential information.


                                       6
<PAGE>


     (e)  The obligations under this provision shall survive and continue for
          one year after termination of this Research Agreement, at which time
          Princeton shall return any and all proprietary data or confidential
          information to the Sponsor; provided, however, that Princeton may keep
          one copy of any form of such proprietary data or confidential
          information for archival purposes.

13.  Indemnification

     Sponsor agrees to indemnify and hold Princeton harmless from any loss,
     claim, damage, or liability of any kind involving an employee of Sponsor
     arising out of or in connection with this Agreement, except to the extent
     that such loss, claim, damage, or liability arises in whole or in part from
     the gross negligence or willful misconduct of Princeton.

14.  Warranties

     Princeton makes no warranties, express or implied, as to any matter
     whatsoever, including, without limitation, the condition of the research or
     any inventions(s) or product(s), whether tangible or intangible, conceived,
     discovered, or developed under this Agreement; or the ownership,
     merchantability, or fitness for a particular purpose of the research or any
     such invention or product. Princeton shall not be liable for any direct,
     consequential, or other damages suffered by any licensee or any others
     resulting from the use of the research or any such invention or product,
     except to the extent such damages result from the sole negligence of
     Princeton.

15.  Equipment

     Title to any equipment purchased or manufactured in the performance of the
     work funded under the Agreement shall vest in Princeton.

16.  Assignment

     Neither party shall assign this Agreement to another without the prior
     written consent of the other party, which will not be unreasonably
     withheld; provided, however, that Sponsor may assign this Agreement to a
     successor in ownership of all or substantially all its business assets.
     Sponsor agrees, however, that this agreement may not be assigned to
     Transcell Technologies Inc. without the express written agreement of
     Princeton. Such successor shall expressly assume in writing the obligation
     to perform in accordance with the terms and conditions of this Agreement.
     Any other purported assignment shall be void.

17.  Independent Inquiry

     Nothing in this Agreement shall be construed to limit the freedom of
     researchers who are not participants in this Agreement from engaging in
     similar research inquiries made independently under other grants, contracts
     or agreements with parties other than Sponsor.

18.  Governing Law

     This Agreement shall be governed by the laws of the State of New Jersey.


IN WITNESS WHEREOF, the parties hereto have executed this Agreement in duplicate

                                 ATTACHMENT 1.46

                                 SIDE AGREEMENT

     REFERENCE IS MADE to (i) the License Agreement between Transcell
Technologies, Inc. ("Transcell") and the Trustees of Princeton University
("Princeton") effective as of October 14, 1993, as amended (the "Princeton
License Agreement"), (ii) the Research Agreement between Princeton and
Interneuron Pharmaceuticals, Inc. ("Interneuron") dated as of April 29, 1997
(the "Princeton Research Agreement") and (iii) the draft Research Collaboration
and License Agreement among Merck & Co., Inc. ("Merck"), Transcell and
Interneuron (the "Merck/Transcell Collaboration Agreement").

     WHEREAS, a portion of the collaboration contemplated by the Merck/Transcell
Collaboration Agreement includes the construction by Dr. Daniel Kahne of a [*]
library in order to identify new antibacterial agents based upon [*]; and

     WHEREAS, pursuant to the Merck/Transcell Collaboration Agreement, Transcell
and Interneuron are granting to Merck exclusive licenses and sub-licenses
limited to the field of certain antibacterial agents with an option to obtain
exclusive licenses and sub-licenses limited to a specified expanded field of
antibacterial agents, such sub-licenses (the "Merck Rights") being granted to
Merck under Transcell's and Interneuron's exclusive rights pursuant to the
Princeton License Agreement and the Princeton Research Agreement and any
subsequent license agreement entered into between Princeton and Transcell or
between Princeton and Interneuron related to such agreements; and

     WHEREAS, Merck, Transcell, Interneuron and Princeton (the "Parties") desire
to set forth the relative rights of the Parties related to certain matters under
the Princeton License Agreement, the Princeton Research Agreement and the
Merck/Transcell Collaboration Agreement. In view of the foregoing, the Parties
agree as follows:

1.        Merck agrees that the following provisions of the Princeton License
     Agreement shall apply to Merck as if it were the Licensee thereunder, to
     the extent, and only to that extent, that such provisions relate to the
     Merck Rights and to the activities of Merck pursuant to the Merck/Transcell
     Collaboration Agreement: Section 2.4 (manufacture in the U.S.), Section
     10.2 (indemnification), Article 12 (non-use of names) and Article 13
     (export controls). All other rights and obligations of the Licensee under
     the Princeton License Agreement shall be rights and obligations of
     Transcell only, except as otherwise provided in this Side Agreement. The
     obligations of Interneuron under the Princeton Research Agreement and under
     any license agreement entered into by Princeton and Interneuron pursuant to
     the Princeton Research Agreement shall be the obligations of Interneuron
     only and shall not be binding upon 


<PAGE>


     Merck, except as otherwise provided in this Side Letter or agreed to in
     writing by Merck.

2.        In connection with the research project contemplated by the Princeton
     Research Agreement, Princeton agrees that all publications or presentations
     (including any student thesis or dissertation) subject to Section 8 of the
     Princeton Research Agreement and subject to the Merck Rights shall, after
     Interneuron's receipt of same from Princeton, be submitted by Interneuron
     to Merck for review prior to submission to the publisher or prior to
     presentation. In addition to any rights of Interneuron under the Princeton
     Research Agreement, upon Merck's request, Interneuron may then request that
     Princeton delay publication or presentation for a maximum of an additional
     60 days to protect the patentability of any inventions described therein.
     Such delay shall not be imposed on the filing of any student thesis or
     dissertation for the purposes of fulfilling academic requirements.

3.        Notwithstanding the provisions of Article 6 of the Princeton License
     Agreement and of Section 7(c) of the Princeton Research Agreement, the
     Parties agree that Merck shall have the right to file, prosecute and
     maintain patent applications and patents relating to research information
     and inventions owned jointly by Merck and Princeton which are subject to
     the Merck Rights. In addition, if Transcell or Interneuron, as the case may
     be, elects not to file, prosecute or maintain patent applications and
     patents covering Princeton-owned inventions subject to the Princeton
     License Agreement or the Princeton Research Agreement and subject to the
     Merck Rights, Merck shall have the right to prosecute and maintain such
     patent applications and patents, if rights thereunder are sublicensed to
     Merck under the Merck/Transcell Collaboration Agreement. The rights granted
     by and exercised under this paragraph shall have no effect on the rights of
     ownership of any patent rights or inventions which shall be governed by
     applicable patent laws and applicable provisions of the Princeton License
     Agreement, the Princeton Research Agreement and the Merck/Transcell
     Collaboration Agreement.

4.        Notwithstanding the provisions of Article 9 of the Princeton License
     Agreement, the Parties agree that, if Transcell or Interneuron, as the case
     may be, elects not to initiate and prosecute a patent infringement action
     or to defend against a declaratory judgment action relating to patents
     arising out of the Princeton License Agreement or the Princeton Research
     Agreement which are subject to the Merck Rights, Merck shall have the right
     either to initiate and prosecute such patent enforcement action or to
     control the defense of such declaratory judgment action under the terms and
     conditions set forth in the Merck/Transcell Collaboration Agreement, if
     rights under the relevant patent are sublicensed to Merck under the
     Merck/Transcell Collaboration Agreement. The rights granted by and
     exercised under this paragraph shall have no effect on the rights of
     ownership of any patent rights or inventions which shall be governed by
     applicable patent laws and applicable provisions of the Princeton License
     Agreement, the Princeton Research Agreement and the Merck/Transcell
     Collaboration Agreement.

5.        Notwithstanding Section 7.1 of the Princeton License Agreement, the 
     Parties agree that in the event that Transcell becomes bankrupt, or shall
     file a petition in bankruptcy, or if the business of Transcell shall be
     placed in the hands of a receiver, assignee or trustee for the benefit of
     creditors, whether by the voluntary act of Transcell or otherwise, (i) the
     Princeton License Agreement shall not terminate with respect to the rights
     granted to Merck under the Merck/Transcell Collaboration Agreement, (ii)
     Merck shall retain and may fully exercise all of its rights and elections
     under the Bankruptcy Code as sub-licensee of such rights and (iii) upon
     Merck's request, Merck and Princeton shall negotiate in good faith an
     agreement providing for the assumption by Merck of Transcell's rights and
     obligations under the Princeton License Agreement with respect to the
     rights granted to Merck under the Merck/Transcell Collaboration Agreement.

6.        The Parties agree that a copy of any notice of Transcell's failure to 
     pay or any other material breach or default by Transcell under Sections 7.2
     or 7.3 of the Princeton License Agreement shall be sent to Merck as
     follows: Merck & Co., Inc., One Merck Drive, P.O. Box 100, Whitehouse
     Station, NJ 08889-0100, Attention Office of Secretary, Telecopier No.:
     (908) 735-1246, with a copy to Attention: Office of Assistant General
     Counsel, Telecopier No.: (908) 735-1226. If Transcell fails to cure such
     breach within the specified period, Merck shall have the right, but not the
     obligation, to cure such non-payment or other breach on Transcell's behalf
     within 30 days of notice to Merck of such failure to cure. In such event,
     Princeton shall not have the right to terminate the Princeton License
     Agreement pursuant to Sections 7.2 or 7.3 of the Princeton License
     Agreement and Merck may credit any amount so paid to Princeton or the
     direct and reasonable costs of effecting such other cure on behalf of
     Transcell against the amounts then due and owing from Merck to Transcell.

7.        Princeton and Transcell agree that they will not amend the Princeton
     License Agreement so as to make such agreement inconsistent with Merck's
     rights under, or in violation of, this Side Agreement or the
     Merck/Transcell Collaboration Agreement without Merck's written consent.

8.        Princeton and Interneuron agree that they will not amend the Princeton
     Research Agreement so as to make such agreement inconsistent with, or in
     violation of, Merck's rights under this Side Agreement or the
     Merck/Transcell Collaboration Agreement without Merck's written consent.
     Princeton and Interneuron further agree they will not enter into any
     license agreement pursuant to the Princeton Research Agreement upon terms
     which are inconsistent with, or in violation of, Merck's rights under this
     Side Agreement or the Merck/Transcell Collaboration Agreement without
     Merck's written consent.

9.        Princeton hereby consents to (i) the sublicense by Transcell to Merck
     pursuant to the Merck/Transcell Collaboration Agreement of certain of
     Transcell's rights under the Princeton License Agreement and (ii) the
     sublicense by Interneuron to Merck 


                                       3
<PAGE>


     pursuant to the Merck/Transcell Collaboration Agreement of certain of
     Interneuron's rights under the Princeton Research Agreement and any license
     agreement entered into pursuant to the Princeton Research Agreement.

10.       This Agreement shall be effective as of June 30, 1997 and shall be 
     governed by the laws of the State of New Jersey without reference to any
     rules of conflict of laws. This Agreement may be executed in two or more
     counterparts, each of which shall be deemed an original, but all of which
     together shall constitute one and the same instrument.

                         TRANSCELL AND MERCK ENTER INTO

                      ANTI-BACTERIAL RESEARCH COLLABORATION


LEXINGTON, MA and PRINCETON,  NJ, July , 1997 - Transcell Technologies,  Inc., a
majority-owned  subsidiary of Interneuron  Pharmaceuticals,  Inc. (NASDAQ: IPIC)
and  Interneuron  today  announced  that they have entered into a  collaborative
research and licensing  agreement with Merck & Co., Inc. (NYSE: MRK) to discover
and commercialize novel antibacterial agents.

The initial focus of this  collaboration  will be the  discovery and  biological
evaluation of analogues of anti-bacterial  compounds  selected from two distinct
structural  classes and the license to Merck of any products  arising out of the
two research programs.  Transcell will utilize its combinatorial technologies to
prepare libraries of carbohydrate derivative compounds for biological evaluation
and further development.  Additionally,  Merck has an option to extend the field
of the  collaboration  and license to include all  antibacterial  pharmaceutical
products.

Under this agreement, Transcell receives from Merck an initial licensing payment
and  research  support  over two years.  In  addition,  Transcell  will  receive
additional  payments based upon the  achievement of defined  milestones for each
program.  While there is no assurance these  milestones  will be reached,  these
additional  payments,  combined with the initial  licensing payment and research
support,  could total  approximately  $48,000,000 if products from both programs
were approved by the FDA. In addition,  Transcell would receive royalty payments
on sales of any products that may be developed based on the research programs.

Certain of the  rights  licensed  to Merck are based on  exclusive  licenses  or
rights held by Transcell and Interneuron from Princeton  University,  which will
be entitled to varying  percentages of certain  payments and royalties  received
from Merck. Transcell's combinatorial  carbohydrate technology is based upon the
research of its scientific  founders,  .Dr. Daniel Kahne and .Dr. Suzanne Walker
of Princeton University.

"Merck's  recognition  that  Transcell's  platform of synthetic  chemistries and
combinatorial  technologies can add significant value to its antibacterial  drug
discovery programs is a very important step in our development of the technology
for drug  discovery in several  therapeutic  areas,"  said  Vincent L.  Fabiano,
executive  vice  president and chief  operating  officer of  Transcell.  "We are
pleased to have  Merck as our first drug  discovery  partner.  Our  partnership,
which  initially  will provide Merck access to libraries of new analogues of two
antibiotics,   has  the  potential  for  expansion   into  the  broad  field  of
antibacterial drug discovery."

Transcell   Technologies,    a   majority-owned    subsidiary   of   Interneuron
Pharmaceuticals,  is exploiting  the  molecular  diversity of  carbohydrates  to
discover novel small molecule pharmaceutical products.

Interneuron  Pharmaceuticals is a diversified  biopharmaceutical company engaged
in the development and  commercialization of a portfolio of products and product
candidates primarily for neurological and behavioral  disorders.  Interneuron is
also developing products and technologies, generally outside the central nervous
system field,  through three other  subsidiaries:  Intercardia,  Inc. focused on
cardiovascular disease,  Progenitor, Inc. focused on developmental genomics, and
InterNutria, Inc. focused on dietary supplement products.

Except for the descriptions of historical facts contained  herein,  this release
contains  forward-looking  statements  that involve risks and  uncertainties  as
detailed from time to time in Interneuron's SEC filings under the Securities Act
of 1933 and the Securities  Exchange Act of 1934 under "Risk Factors" that could
cause Interneuron's  actual results to differ significantly from those discussed
in the forward-looking  statements,  including the early stage of development of
Transcell's  technology,   uncertainties  related  to  preclinical  development,
corporate collaborations,  clinical trials, patent risks, government regulation,
and dependence on third parties for manufacturing and marketing.

                          ARTICLE II - GRANT OF LICENSE

     2.1 PRINCETON hereby grants to LICENSEE an exclusive (even as to Princeton)
worldwide license, with the right to sublicense, under the Patent Rights to
make, have made, use, lease and/or sell the [ * ] and Licensed Product(s), and
to use, lease, and/or sell the Assay or Licensed Process(es) to the full end of
the term for which the Patent Rights are granted unless sooner terminated as
hereinafter provided.

     2.2 LICENSEE agrees to use commercially reasonable efforts to provide that
LICENSED PRODUCTS leased or sold in the United States shall be manufactured
substantially in the United States.

     2.3 PRINCETON expressly reserves the right to use the Patent Rights,
Licensed Products, Licensed Processes, and associated information and technology
for Princeton's own educational, research and other non-commercial purposes
only, provided, however, that PRINCETON shall notify LICENSEE of any additional
intellectual property that may arise from such use and shall offer LICENSEE a
first option to license such technology on terms and conditions to be negotiated
in good faith between the Parties, such option to be exercised within six (6)
months of disclosure of the invention by PRINCETON to LICENSEE.

     2.4 LICENSEE shall have the right to sublicense the Patent Rights granted
pursuant to this Agreement to any Third Party; provided that LICENSEE shall not
grant any such Sublicense without Princeton's written consent, which consent
shall not be unreasonably withheld.

     2.5 LICENSEE agrees that any sublicenses granted by it shall have privity
of contract between PRINCETON and Sublicensee such that the obligations of this
Agreement shall be binding upon the Sublicensee as if it were in the place of
LICENSEE. LICENSEE further agrees to attach copies of Articles II, V, VII, IX,
X, XII, XIII, and XV of this Agreement to all sublicense agreements,

     2.6 LICENSEE agrees to forward to PRINCETON a copy of any and all fully
executed sublicense agreements, and further agrees to forward to PRINCETON
annually a copy of such reports received by LICENSEE from its Sublicensees
during the preceding twelve (12) month period under the sublicenses as shall be
pertinent to a royalty accounting under said sublicense agreements.

                           ARTICLE III - DUE DILIGENCE

     3.1 LICENSEE shall use its best efforts to commercialize the Licensed
Product(s) and/or Licensed Process(es) through a thorough, vigorous and diligent
program for exploitation of the Patent Rights. The progress and results of
LICENSEE's efforts shall be reported to PRINCETON through annual reports.

     3.2 A sublicense by LICENSEE of the Patent Rights in accordance with the
terms of this Agreement shall satisfy the obligations of LICENSEE set forth in
Section 3.1; provided, however, that if the sublicense is terminated with
respect to a Licensed Product, LICENSEE shall continue to have the obligations
set forth in Section 3.1. In such event, LICENSEE shall also submit a
development plan to PRINCETON on an annual basis relating to the budget and
estimated time for development of Licensed Products.

     3.3 LICENSEE's failure to perform in accordance with Paragraphs 3.1 and 3.2
above shall be grounds for PRINCETON to have the right to terminate this
Agreement pursuant to Paragraph 7.3 hereof.

                       ARTICLE IV - ROYALTIES AND PAYMENTS

     4.1 For the rights, privileges and license granted hereunder, LICENSEE
shall pay to PRINCETON in the manner hereinafter provided to the end of the term
of the Patent Rights or until this Agreement shall be terminated as hereinafter
provided:

          (a) A License Issue Fee of One Hundred Sixty Thousand Dollars
          ($160,000), which shall be deemed earned immediately upon the
          execution of this Agreement and payable upon such execution.

          (b) License Maintenance Fees of Fifty Thousand Dollars ($50,000) per
          year, payable on each anniversary of the Effective Date of this
          Agreement until the earlier of the year in which the first commercial

          of the Agreement occurs.

          (c) Running royalties in an amount equal to one percent (1%) of Net
          Revenues, provided, however, that fifty percent (50%) of any other
          royalties or payments accrued or paid by LICENSEE to a Third Party in
          connection with the manufacture, use, or sale of [ * ], Licensed
          Product(s), Compound(s), Assay(s), or Licensed Process(es) may be
          deducted from the amounts due under this Paragraph.

                              with the Commission.


          (d) Milestone payment of one million dollars ($1,000,000) payable
          within ten (10) days after filing a New Drug Application with the Food

          (e) A payment in an amount equal to Twenty-Five Percent (25 %) of any
          Sublicense Fees received by LICENSEE from a Sublicensee of Licensed
          Product or Licensed Process, payable within ten (10) days of signing
          of such Sublicense Agreement.

     4.2 No multiple royalties shall be payable to PRINCETON pursuant to the
License if the manufacture, use or sale of a [ * ] or Licensed Product or
practice of the Assay or Licensed Process is covered by more than one patent
application or patent contained in the Patent Rights, if such royalty or payment
may be covered under more than one of the above provisions, or if a royalty is
payable to PRINCETON in connection with the manufacture, use or sale of such
Licensed Product or Compound under any other License agreement between PRINCETON
and LICENSEE; provided, however, that if a royalty would be payable to PRINCETON
under such other license agreement, then for such Licensed Product or Compound,
PRINCETON shall be entitled to select, by notifying LICENSEE in writing prior to
the First Commercial Sale of such Licensed Product or Compound, whether to
receive the royalty rate set forth under this Agreement or the royalty rate set
forth under such other license agreement.

     4.3 Royalty payments shall be paid in United States dollars in Princeton,
New Jersey, or at such other place as PRINCETON may reasonably designate
consistent with the laws and regulations controlling in any foreign country. Any
withholding taxes which LICENSEE or any Sublicensee shall be required by law to
withhold on remittance of the royalty payments shall be deducted from royalties
paid to PRINCETON. LICENSEE shall furnish PRINCETON with copies of all official
receipts for such taxes. If any currency conversion shall be required in
connection with the payment of royalties hereunder, such conversion shall be
made by using the exchange rate prevailing at a first-class foreign exchange
bank on the last business day of the calendar quarterly reporting period to
which such royalty payments relate.

                         ARTICLE V - REPORTS AND RECORDS

     5.1 LICENSEE shall keep full, true and accurate books of account containing
all particulars that may be necessary for the purpose of showing the amount
payable to PRINCETON by way of royalty as aforesaid. Said books of account shall
be kept at LICENSEE's principal place of business or the principal place of
business of the appropriate division of LICENSEE to which this Agreement
relates. Said books and the supporting data shall be open at all reasonable
times, for three (3) years following the end of the calendar year to which they
pertain, to the 


                                       6

inspection of the PRINCETON Internal Audit Division and/or an independent
certified public accountant retained by PRINCETON and/or a certified public
accountant employed by PRINCETON for the purpose of verifying LICENSEE's royalty
statement or compliance in other respects with this Agreement.

     5.2 LICENSEE, within forty-five (45) days after March 31, June 30,
September 30 and December 31, of each year, shall deliver to PRINCETON true and
accurate reports, giving such particulars of the business conducted by LICENSEE

royalty accounting hereunder. These shall include at least the following:

          (a) All Licensed Products manufactured and sold.

          (b) Total amounts actually received by LICENSEE on account of its
          billings for Licensed Product sold.

          (c) Accounting for all the Licensed Process(es) used or sold.

          twelve (12) months including, at a minimum, a Balance Sheet and an
          Operating Statement.

     5.3 With each such report submitted, LICENSEE shall pay to PRINCETON the
royalties due and payable under this Agreement, provided that no payment to
PRINCETON shall be payable in the event that the remittance of royalties from
foreign countries to the accounts of LICENSEE in the United States shall be
blocked by exchange controls in foreign countries, which exchange controls are
beyond the control of LICENSE, in which case, such royalties shall be held in
escrow and paid to PRINCETON at such time as such exchange controls are no
longer blocked. If no royalties shall be due, LICENSEE shall so report.

                         ARTICLE VI - PATENT PROSECUTION

     6.1 PRINCETON and LICENSEE agree to cooperate fully in applying for,
obtaining, prosecuting and maintaining patents.

<PAGE>



     6.2 For inventions originating under the Research Program, PRINCETON shall
promptly disclose to LICENSEE, in writing, any PRINCETON-owned or Jointly-owned
Inventions disclosed to PRINCETON. PRINCETON shall file and prosecute U.S. and
foreign patent applications in its name at LICENSEE's request and expense, using
mutually agreed upon patent counsel, on such PRINCETON-owned or Jointly-owned
Inventions as may, in LICENSEE's judgement, become appropriate during the term
of this Agreement.

     6.3 For inventions originating under the Research Program, PRINCETON shall
have the opportunity to file patent applications in its name at its own expense
for those PRINCETON-owned or Jointly-owned Inventions made by its personnel and
for which LICENSEE does not agree, within thirty (30) days after notification by
PRINCETON of its intent to file a patent application, to pay for PRINCETON to
file said patent applications.

     6.4 LICENSEE's patent counsel may prepare, file and prosecute all U.S.
applications for any Jointly-owned Inventions, at LICENSEE's sole cost and
expense, provided, however, that PRINCETON shall have the right to review and
approve the application, and be consulted on all prosecution actions, and
foreign filing decisions. PRINCETON's right, title and interest in the
Jointly-owned Inventions disclosed or claimed in such patent applications or in
any such patents shall be subject to the terms of this Agreement.

                            ARTICLE VII - TERMINATION

     7.1 If LICENSEE shall become bankrupt or insolvent, or shall file a
petition in bankruptcy, or if the business of LICENSEE shall be placed in the
hands of a receiver, assignee or trustee for the benefit of creditors, whether
by the voluntary act of LICENSEE or otherwise, this Agreement shall
automatically terminate.

     7.2 Should LICENSEE fail in its payment to PRINCETON of royalties due in
accordance with the terms of this Agreement, PRINCETON shall have the right to
serve notice upon LICENSEE by certified mail at the address designated in
Article XIV hereof, of its intention to terminate this Agreement within thirty
(30) days after receipt of said notice of termination unless LICENSEE shall pay
to PRINCETON, within the thirty (30) day period, all such royalties due and
payable. Upon the expiration of the thirty (30) day period, if LICENSEE shall
not have paid all such royalties due and payable, the rights, privileges and
license granted hereunder shall thereupon immediately terminate.

     7.3 Upon any material breach or default of this Agreement by LICENSEE,
other than those occurrences set out in Paragraphs 7.1 and 7.2 hereinabove,
which shall always take precedence in that order over any material breach or
default referred to in this Paragraph 7.3, 


                                       8
<PAGE>



PRINCETON shall have the right to terminate this Agreement and the rights,
privileges and license granted hereunder by ninety (90) days' notice by
certified mail to LICENSEE Agreement. Such termination shall become effective
unless LICENSEE shall have cured any such breach or default prior to the
expiration of the ninety (90) day period from receipt of PRINCETON notice of
termination.

     7.4 LICENSEE shall have the right to terminate this Agreement at any time
on six (6) months' notice by certified mail to PRINCETON in whole or with
respect to designated countries or designated Patent Rights, Licensed Products
or Licensed Processes.

     7.5 Upon termination of this Agreement for any reason, nothing herein shall
be construed to release either party from any obligation that matured prior to
the effective date of such termination. LICENSEE and/or any Sublicensee thereof
may, however, after the effective date of such termination, sell all Licensed
Products, and complete Licensed Products in the process of manufacture at the
time of such termination and sell the same, provided that LICENSEE shall pay to
PRINCETON the royalties thereon as required by Article IV of this Agreement and
shall submit the reports required by Article V hereof on the sales of Licensed
Products.

                           ARTICLE VIII - ARBITRATION

     8.1 Except as to issues relating to the validity, construction or effect of
any patent licensed hereunder, any and all claims, disputes or controversies
arising under, out of, or in connection with this Agreement, which have not been
resolved by good faith negotiations between the parties, shall be resolved by
final and binding arbitration in Princeton, New Jersey under the rules of the
American Arbitration Association then obtaining. The arbitrators shall have no
power to add to, subtract from or modify any of the terms or conditions of this
Agreement. Any award rendered in such arbitration may be enforced by either
party in either the courts of the State of New Jersey or in the United States to
whose jurisdiction for such purposes PRINCETON and LICENSEE each hereby
irrevocably consents and submits.

     8.2 Claims, disputes or controversies concerning the validity, construction
or effect of any patent licensed hereunder shall be resolved in any court having
jurisdiction thereof.

     8.3 In the event that, in any arbitration proceeding, any issue shall arise
concerning the validity, construction or effect of any patent licensed
hereunder, the arbitrators shall assume the validity of all claims as set forth
in such patent; in any event the arbitrators shall not delay the arbitration
proceeding for the purpose of obtaining or permitting either party to obtain
judicial resolution of such issue, unless an order staying such arbitration
proceeding shall be entered by a court of competent jurisdiction. Neither party
shall raise any issue concerning the validity, 


                                       9
<PAGE>


 
construction or effect of any patent licensed hereunder in any proceeding to
enforce any arbitration award hereunder or in any proceeding otherwise arising
out of any such arbitration award.

                            ARTICLE IX - INFRINGEMENT

     9.1 LICENSEE and PRINCETON shall promptly inform the other in writing of
any alleged infringement of which it shall have notice by a third party of any
patents within the Patent Rights and provide such other with any available
evidence of infringement.

     9.2 During the term of this Agreement, LICENSEE shall have the right, but
shall not be obligated, to prosecute at its own expense any such infringements
of the Patent Rights and, in furtherance of such right, PRINCETON hereby agrees
that LICENSEE may join PRINCETON as a party plaintiff in any such suit, without
expense to PRINCETON. The total cost of any such infringement action commenced
or defended solely by LICENSEE shall be borne by LICENSEE, and LICENSEE shall
keep any recovery or damages for past infringement derived therefrom. No
settlement, consent judgment or other voluntary final disposition of the suit
may be entered into without the consent of PRINCETON, which consent shall not
unreasonably be withheld. LICENSEE shall indemnify PRINCETON against any order
for costs that may be made against PRINCETON in such proceedings.

     9.3 If within six (6) months after having been notified of any alleged
infringement, LICENSEE shall have been unsuccessful in persuading the alleged
infringer to desist and shall not have brought and shall not be diligently
prosecuting an infringement action, or if LICENSEE shall notify PRINCETON at any
time prior thereto of its intention not to bring suit against any alleged
infringer, then, and in those events only, PRINCETON shall have the right, but
shall not be obligated, to prosecute at its own expense any infringement of the
Patent Rights, and PRINCETON may, for such purposes, join LICENSEE as party
plaintiff.

     9.4 In the event that LICENSEE shall undertake the enforcement and/or
defense of the Patent Rights by litigation, LICENSEE may withhold up to fifty
percent (50%) of the royalties otherwise thereafter due PRINCETON hereunder and
apply the same toward reimbursement of its expenses, including reasonable
attorneys' fees, in connection therewith. Any recovery of damages by LICENSEE
for any such suit shall be applied first in satisfaction of any unreimbursed
expenses and legal fees of LICENSEE relating to the suit, and next toward
reimbursement of PRINCETON for any royalties past due or withheld and applied
pursuant to this Article IX. The balance remaining from any such recovery shall
be divided equally between LICENSEE and PRINCETON.


                                       10
<PAGE>



     9.5 In the event that a declaratory judgement action alleging invalidity or
non-infringement of any of the Patent Rights shall be brought against LICENSEE,
and LICENSEE is not diligently defending such action, PRINCETON, at its option,
shall have the right, within ninety (90) days after commencement of such action,
to intervene and take over the sole defense of the action at its own expense.

     9.6 In any infringement suit as either party may institute to enforce the
Patent Rights pursuant to this Agreement, the other party hereto shall, at the
request and expense of the party initiating such suit, cooperate in all respects
and, to the extent possible, have its employees testify when requested and make
available relevant records, papers, information, samples, specimens, and the
like.

     9.7 LICENSEE, during the exclusive period of this Agreement, shall have the
sole right in accordance with the terms and conditions herein to sublicense any
alleged infringer under the Patent Rights for future infringements.

                          ARTICLE X - PRODUCT LIABILITY

     10.1 PRINCETON by this Agreement makes no representation as to the
patentability and/or breadth of the inventions and/or discoveries involved in a
Licensed Patent. PRINCETON by this Agreement makes no representation as to
patents now held or which will be held by others in the field of the Licensed
Products for a particular purpose.

     10.2 LICENSEE agrees to defend, indemnify and hold PRINCETON, its Trustees,
Officers, Agents, Employees and Students harmless from and against all
liability, demands, damages, expense or losses for death, personal injury,
illness or property damage arising (a) out of use by LICENSEE or its transferees
of inventions licensed or information furnished under this Agreement, or (b) out
of any use, sale or other disposition by LICENSEE, its Affiliates, Subsidiaries,
Contractors and Subcontractors, or its transferees of products made by use of
such inventions or information.

     10.3 In discharge of the above, on or prior to the date on which a clinical
trial commences with respect to a Licensed Product ("the Insurance Commencement
Date"), LICENSEE will maintain general liability insurance in the amount of at
least One Million Dollars ($1,000,000) per occurrence with a deductible of not
more than $10,000 per occurrence with commercially reasonable insurers against
damage to or destruction of property and injury to or death of individuals and
against such other risks as PRINCETON may reasonably request arising out of or
in connection with any of the Licensed Products. PRINCETON, and its respective
officers, trustees, and employees will be named insureds under all such
insurance. Such insurance 


                                       11
<PAGE>



will also provide that PRINCETON will be given notice of any modification
thereof and at least ten (10) days' prior written notice of cancellation or
termination and the reason therefore. LICENSEE will furnish PRINCETON upon
request, and in any event on the Insurance Commencement Date and on each
anniversary of the Insurance Commencement Date, written confirmation issued by
the insurer or an independent insurance agent confirming that insurance is
maintained in accordance with the above requirements.

                             ARTICLE XI - ASSIGNMENT

     11.1 LICENSEE may assign or otherwise transfer this Agreement and the
license granted hereby and the rights acquired by it hereunder, so long as such
assignment or transfer shall be to an Affiliate, or shall be accompanied by a
sale or other transfer of LICENSEE's entire business or of that part of
LICENSEE's business to which the license granted hereby relates or as PRINCETON
may otherwise consent, which consent shall not be unreasonably withheld.
LICENSEE shall give PRINCETON thirty (30) days' prior notice of any such
assignment and transfer requiring PRINCETON's consent, and if PRINCETON raises
no reasonable objection to such assignment or transfer, in writing within thirty
(30) days after the giving of such notice and stating the reasons for such
objection, then PRINCETON shall be deemed to have approved such assignment or
transfer; provided, however, PRINCETON shall not be deemed to have approved such
assignment and transfer unless such assignee or transferee shall have agreed in
writing to be bound by the terms and conditions of this Agreement. Upon such
assignment or transfer and agreement by such assignee or transferee, the term
LICENSEE as used herein shall include such assignee or transferee. If LICENSEE
shall sell or otherwise transfer its entire business or that part of its
business to which the license granted hereby relates and the transferee shall
not have agreed in writing to be bound by the terms and conditions of this
Agreement, or new terms and conditions shall not have been agreed upon within
sixty (60) days of such sale or transfer, PRINCETON shall have the right to
terminate this Agreement.

                         ARTICLE XII - NON-USE OF NAMES

     12.1 LICENSEE shall not use the name of PRINCETON nor any adaptation
thereof in any advertising, promotional or sales literature without prior
written consent obtained from PRINCETON, in each case, except that LICENSEE may
state that it is licensed by PRINCETON under one or more of the patents and/or
applications comprising the Patent Rights.

                         ARTICLE XIII - EXPORT CONTROLS

     13.1 It is understood that PRINCETON is subject to United States laws and
regulations controlling the export of technical data, computer software,
laboratory prototypes and other commodities (including the Arms Export Control
Act, as amended, and the Export Administration Act of 1979), and that its
obligations hereunder are contingent on compliance with applicable United States
export laws and regulations. The transfer of certain technical data and
commodities may require a license from the cognizant agency of the United States
Government and/or written assurances by LICENSEE that LICENSEE shall not export
data or commodities to certain foreign countries without prior approval of such
agency. PRINCETON neither represents that a license shall not be required nor
that, if required, it shall be issued.

                         ARTICLE XIV - PAYMENTS, NOTICES
                            AND OTHER COMMUNICATIONS

     15.1 This Agreement shall be construed, governed, interpreted and applied
in accordance with the laws of the State of New Jersey, except that questions
affecting the construction and effect of any patent shall be determined by the
law of the country in which the patent was granted.

any provision of this Agreement shall be determined to be invalid or
unenforceable under any controlling body of law, such invalidity or
unenforceability shall not in any way affect the validity or enforceability of
the remaining provisions hereof.

     15.4 LICENSEE agrees to mark the Licensed Products sold in the United
States with all applicable United States patent numbers. All Licensed Products
shipped to or sold in other countries shall be marked in such a manner as to
confirm with the patent laws and practice of the country of manufacture or sale.

     15.5 The failure of either party to assert a right hereunder or to insist
upon compliance with any term or condition of this Agreement shall not
constitute a waiver of that right or excuse a similar subsequent failure to
perform any such term or condition by the other party.

     (c)  In the event LICENSEE is selling Licensed Products directly, a royalty
          in an amount equal to (i) three percent of Net Revenues in any year of

          may be deducted from the amounts due under this Paragraph.

     (e)  A payment in an amount equal to Fifty Percent (50%) of any Sublicense
          Fees received by LICENSEE from a Sublicensee of Licensed Product,

          the Effective Date of this Agreement and payable within ten (10) days

          (v)  10% of cumulative Milestone Payments greater than $14.5 Million.

     4.2 No multiple royalties shall be payable to PRINCETON pursuant to the
License if the manufacture, use or sale of a Licensed Product or practice of the
Licensed Process is covered by more than one patent application or patent
contained in the Patent Rights, if such royalty or payment may be covered under
more than one of the above provisions, or if a royalty is payable in connection
with the manufacture, use, or sale of such Licensed Product under the Transcell
License Agreement, provided, however, that if a royalty would be payable to
Princeton in connection with the manufacture, use or sale of such Licensed
Product under the Transcell License Agreement, then for such Licensed Product,
PRINCETON shall be entitled to select, by notifying LICENSEE in writing prior to
the First Commercial Sale of such Licensed Product, whether to receive the
royalty rate set forth under this Agreement or the royalty rate set forth under
the Transcell License Agreement.

     4.3 Royalty payments shall be paid in United States dollars in Princeton,
New Jersey, or at such other place as PRINCETON may reasonably designate
consistent with the laws and regulations controlling in any foreign country. Any
withholding taxes which LICENSEE or any Sublicensee shall be required by law to
withhold on remittance of the royalty payments shall be deducted from royalties
paid to PRINCETON. LICENSEE shall furnish PRINCETON with copies of all official
receipts for such taxes. If any currency conversion shall be required in
connection with the payment of royalties hereunder, such conversion shall be
made by using the exchange rate prevailing at a first-class foreign exchange
bank on the last business day of the calendar quarterly reporting period to
which such royalty payments relate, provided, however, that in the event a
calculation is made based on sales by Merck, the rate of exchange to be used in
computing the amount of currency equivalent in United States dollars shall be
made at the rate of exchange utilized by Merck in its worldwide accounting
system, prevailing in the fourth to the last business day of the Calendar
Quarter in which such payments relate. Such rated of exchange is that rate
quoted by Reuters Ltd. for the spot purchase of U.S. dollars at 7:15 a.m.
Eastern Standard Time on such day.

                        ARTICLE V - REPORTS AND RECORDS

     5.1 LICENSEE shall keep full, true and accurate books of account containing
all particulars that may be necessary for the purpose of showing the amount
payable to PRINCETON by way of royalty as aforesaid. Said books of account shall
be kept at LICENSEE's principal place of business or the principal place of
business of the appropriate division of LICENSEE to which this Agreement
relates. Said books and the supporting data shall be open at all reasonable
times, for three (3) years following the end of the calendar year to which they
pertain, to the inspection of the PRINCETON Internal Audit Division and/or an
independent certified public accountant retained by PRINCETON and/or a certified
public accountant employed by PRINCETON for the purpose of verifying LICENSEE's
royalty statement or compliance in other aspects with this Agreement.

     5.2 LICENSEE, within forty-five (45) days after March 31, June 30,
September 30 and December 31 of each year, shall deliver to PRINCETON true and
accurate reports, giving such particulars of the business conducted by LICENSEE
during the preceding quarter under this Agreement as shall be pertinent to a
royalty accounting hereunder. These shall include at least the following:

          (a)  All Licensed Products manufactured and sold.

          (b)  Total amounts actually received by LICENSEE on account of its
               billings for Licensed Product sold.

          (c)  Accounting for all the Licensed Process(es) used or sold.

          (d)  Deductions applicable as provided in Paragraph 1.8.

          (e)  Total royalties due.

               twelve (12) months including, at a minimum, a Balance Sheet and
               an Operating Statement.

     5.3 With each such report submitted, LICENSEE shall pay to PRINCETON the
royalties due and payable under this Agreement, provided that no payment to
PRINCETON shall be payable in the event that the remittance of royalties from
foreign countries to the accounts of LICENSEE in the United States shall be
blocked by exchange controls in foreign countries, which exchange controls are
beyond the control of LICENSE, in which case, such royalties shall be held in
escrow and paid to PRINCETON at such time as such exchange controls are no
longer blocked. If no royalties shall be due, LICENSEE shall so report.

Paragraph 3 of the Side Agreement. Such patent applications and any patents
resulting therefrom shall be subject to the terms of this Agreement.

     6.3 PRINCETON shall have the opportunity to file patent applications in its
name at its own expense for those PRINCETON-owned or Jointly-owned Inventions

days after notification by PRINCETON of its intent to file a patent application,
to pay for PRINCETON to file said patent applications, provided, however, that
notwithstanding the foregoing, Merck shall have the rights set forth in
Paragraph 3 of the Side Agreement. Such patent applications and any patents
resulting therefrom shall not be subject to the terms of this Agreement.

     6.4 LICENSEE patent counsel may prepare, file and prosecute all U.S.
applications for any Jointly-owned Inventions, at LICENSEE's sole cost and
expense, provided, however, that PRINCETON shall have the right to review and
approve the application, and be consulted on all prosecution actions, and
foreign filing decisions. PRINCETON's right, title and interest in the
Jointly-owned Inventions disclosed or claimed in such patent applications or in
any such patents shall be subject to the terms of this Agreement.

                           ARTICLE VII - TERMINATION

     7.1 If LICENSEE shall become bankrupt or insolvent, or shall file a
petition in bankruptcy, or if the business of LICENSEE shall be placed in the
hands of a receiver, assignee or trustee for the benefit of creditors, whether
by the voluntary act of LICENSEE or otherwise, this Agreement shall
automatically terminate, provided, however, that notwithstanding the foregoing,
Merck shall have the rights set forth in Paragraph 5 of the Side Agreement with
respect to this Agreement.

     7.2 Should LICENSEE fail in its payment to PRINCETON of royalties due in
accordance with the terms of this Agreement, PRINCETON shall have the right to
serve notice upon LICENSEE by certified mail at the address designated in
Article XIV hereof, of its intention to terminate this Agreement within thirty
(30) days after receipt of said notice of termination unless LICENSEE shall pay
to PRINCETON, within the thirty (30) day period, all such royalties due and
payable. Upon the expiration of the thirty (30) day period, if LICENSEE shall
not have paid all such royalties due and payable, the rights, privileges and



                                       9
<PAGE>

license granted hereunder shall thereupon immediately terminate, provided,
however, that notwithstanding the foregoing, Merck shall have the rights set
forth in Paragraph 6 of the Side Agreement in the event of any failure to pay or
other material breach or default by LICENSEE under this Agreement.

     7.3 Upon any material breach or default of this Agreement by LICENSEE,
other than those occurrences set out in Paragraphs 7.1 and 7.2 hereinabove,
which shall always take precedence in that order over any material breach or
default referred to in this Paragraph 7.3, PRINCETON shall have the right to
terminate this Agreement and the rights, privileges and license granted
hereunder by ninety (90) days' notice by certified mail to LICENSEE, provided,
however, that notwithstanding the foregoing, Merck shall have the rights set
forth in Paragraph 6 of the Side Agreement in the event of any failure to pay or
other material breach or default by LICENSEE under this Agreement. Such
termination shall become effective unless LICENSEE shall have cured any such
breach or default prior to the expiration of the ninety (90) day period from
receipt of PRINCETON notice of termination, provided, however, that
notwithstanding the foregoing, Merck shall have the rights set forth in
Paragraph 6 of the Side Agreement in the event of any failure to pay or other
material breach or default by LICENSEE under this Agreement.

     7.4 LICENSEE shall have the right to terminate this Agreement at any time
on six (6) months' notice by certified mail to PRINCETON in whole or with
respect to designated countries or designated Patent Rights, Licensed Products
or Licensed Processes.

     7.5 Upon termination of this Agreement for any reason, nothing herein shall
be construed to release either party from any obligation that matured prior to
the effective date of such termination. LICENSEE and/or any Sublicensee thereof
may, however, after the effective date of such termination, sell all Licensed
Products, and complete Licensed Products in the process of manufacture at the
time of such termination and sell the same, provided that LICENSEE shall pay to
PRINCETON the royalties thereon as required by Article IV of this Agreement and
shall submit the reports required by Article V hereof on the sales of Licensed
Products.

                           ARTICLE VIII - ARBITRATION

     8.1 Except as to issues relating to the validity, construction or effect of
any patent licensed hereunder, any and all claims, disputes or controversies
arising under, out of or in connection with this Agreement, which have not been
resolved by good faith negotiations between the parties, shall be resolved by
final and binding arbitration in Princeton, New Jersey under the rules of the
American Arbitration Association then obtaining. The arbitrators shall have no
power to add to, subtract from or modify any of the terms or conditions of this
Agreement. Any award rendered in such arbitration may be enforced by either
party in either the courts of the State of New Jersey or in the United States to
whose jurisdiction for such purposes PRINCETON and LICENSEE each hereby
irrevocably consents and submits.



                                       10
<PAGE>

     8.2 Claims, disputes or controversies concerning the validity, construction
or effect of any patent licensed hereunder shall be resolved in any court having
jurisdiction thereof.

     8.3 In the event that, in any arbitration proceeding, any issue shall arise
concerning the validity, construction or effect of any patent licensed
hereunder, the arbitrators shall assume the validity of all claims as set forth
in such patent; in any event the arbitrators shall not delay the arbitration
proceeding for the purpose of obtaining or permitting either party to obtain
judicial resolution of such issue, unless an order staying such arbitration
proceeding shall be entered by a court of competent jurisdiction. Neither party
shall raise any issue concerning the validity, construction or effect of any
patent licensed hereunder in any proceeding to enforce any arbitration award
hereunder or in any proceeding otherwise arising out of any such arbitration
award.

                           ARTICLE IX - INFRINGEMENT

     9.1 LICENSEE and PRINCETON shall promptly inform the other in writing of
any alleged infringement of which it shall have notice by a third party of any
patents within the Patent Rights and provide such other with any available
evidence of infringement.

     9.2 During the term of this Agreement, LICENSEE shall have the right, but
shall not be obligated, to prosecute at its own expense any such infringements
of the Patent Rights and, in furtherance of such right, PRINCETON hereby agrees
that LICENSEE may join PRINCETON as a party plaintiff in any such suit, without
expense to PRINCETON, provided, however, that notwithstanding the foregoing,
Merck shall have the rights set forth in Paragraph 4 of the Side Agreement. The
total cost of any such infringement action commenced or defended solely by
LICENSEE shall be borne by LICENSEE, and LICENSEE shall keep any recovery or
damages for past infringements derived therefrom. No settlement, consent
judgment or other voluntary final disposition of the suit may be entered into
without the consent of PRINCETON, which consent shall not unreasonably be
withheld. LICENSEE shall indemnify PRINCETON against any order for costs that
may be made against PRINCETON in such proceedings.

     9.3 If within six (6) months after having been notified of any alleged
infringement, LICENSEE shall have been unsuccessful in persuading the alleged
infringer to desist and shall not have brought and shall not be diligently
prosecuting an infringement action, or if LICENSEE shall notify PRINCETON at any
time prior thereto of its intention not to bring suit against any alleged
infringer, then, and in those events only, PRINCETON shall have the right, but
shall not be obligated, to prosecute at its own expense any infringement of the
Patent Rights, and PRINCETON may, for such purposes, join LICENSEE as party
plaintiff, provided, however, that notwithstanding the foregoing, Merck shall
have the rights set forth in Paragraph 4 of the Side Agreement.

     9.4 In the event that LICENSEE shall undertake the enforcement and/or
defense of the Patent Rights by litigation, LICENSEE may withhold up to fifty
percent (50%) of the royalties otherwise thereafter due PRINCETON hereunder and
apply the same toward



                                       11
<PAGE>

reimbursement of its expenses, including reasonable attorneys' fees, in
connection therewith. Any recovery of damages by LICENSEE for any such suit
shall be applied first in satisfaction of any unreimbursed expenses and legal
fees of LICENSEE relating to the suit, and next toward reimbursement of
PRINCETON for any royalties past due or withheld and applied pursuant to this
Article IX. The balance remaining from any such recovery shall be divided
equally between LICENSEE and PRINCETON.

     9.5 In the event that a declaratory judgment action alleging invalidity or
non-infringement of any of the Patent Rights shall be brought against LICENSEE,
and LICENSEE is not diligently defending such action, PRINCETON, at its option,
shall have the right, within ninety (90) days after commencement of such action,
to intervene and take over the sole defense of the action at its own expense,
provided, however, that notwithstanding the foregoing, Merck shall have the
rights set forth in Paragraph 4 of the Side Agreement.

     9.6 In any infringement suit as either party may institute to enforce the
Patent Rights pursuant to this Agreement, the other party hereto shall, at the
request and expense of the party initiating such suit, cooperate in all respects
and, to the extent possible, have its employees testify when requested and make
available relevant records, papers, information, samples, specimens, and the
like.

     9.7 LICENSEE, during the exclusive period of this Agreement, shall have the
sole right in accordance with the terms and conditions herein to sublicense any
alleged infringer under the Patent Rights for future infringements.

                         ARTICLE X - PRODUCT LIABILITY

     10.1 PRINCETON by this Agreement makes no representation as to the
patentability and/or breadth of the inventions and/or discoveries involved in a
Licensed Patent. PRINCETON by this Agreement makes no representation as to
patents now held or which will be held by others in the field of the Licensed
Products for a particular purpose.

     10.2 LICENSEE agrees to defend, indemnify and hold PRINCETON harmless from
and against all liability, demands, damages, expense or losses for death,
personal injury, illness or property damage arising (a) out of use by LICENSEE
of its transferees of inventions licensed or information furnished under this
Agreement, or (b) out of any use, sale or other disposition by LICENSEE or its
transferees of products made by use of such inventions or information. As used
in this clause, PRINCETON includes its Trustees, Officers, Agents, Employees and
Students and "LICENSEE" includes its Affiliates, Subsidiaries, Contractors and
Sub-Contractors.

     10.3 In discharge of the above, on or prior to the date on which a clinical
trial commences with respect to a Licensed Product (the "Insurance Commencement
Date"), LICENSEE will maintain general liability insurance in the amount of at
least One Million Dollars ($1,000,000) per occurrence with a deductible of not
more than $10,000 per occurrence with commercially reasonable insurers against
damage to or destruction of property



                                       12
<PAGE>

and injury to or death of individuals and against such other risks as PRINCETON
may reasonably request arising out of or in connection with any of the Licensed
Products. PRINCETON, and its respective officers, trustees, and employees, will
be named insureds under all such insurance. Such insurance will also provide
that PRINCETON will be given notice of any modification thereof and at least ten
(10) days prior written notice of cancellation or termination and the reason
therefor. LICENSEE will furnish PRINCETON upon request, and in any event on the
Insurance Commencement Date and on each anniversary of the Insurance
Commencement Date, written confirmation issued by the insurer or an independent
insurance agent confirming that insurance is maintained in accordance with the
above requirements.

                            ARTICLE XI - ASSIGNMENT

     11.1 LICENSEE may assign or otherwise transfer this Agreement and the
license granted hereby and the rights acquired by it hereunder, so long as such
assignment or transfer shall be to an Affiliate (other than Transcell), or shall
be accompanied by a sale or other transfer of LICENSEE's entire business or of
that part of LICENSEE's business to which the license granted hereby relates or
as PRINCETON may otherwise consent, which consent shall not be unreasonably
withheld. LICENSEE shall give PRINCETON thirty (30) days prior notice of any
such assignment and transfer requiring PRINCETON's consent, and if PRINCETON
raises no reasonable objection to such assignment or transfer, in writing within
thirty (30) days after the giving of such notice and stating the reasons for
such objection, then PRINCETON shall be deemed to have approved such assignment
or transfer; provided, however, PRINCETON shall not be deemed to have approved
such assignment and transfer unless such assignee or transferee shall have
agreed in writing to be bound by the terms and conditions of this Agreement.
Upon such assignment or transfer and agreement by such assignee or transferee,
the term LICENSEE as used herein shall include such assignee or transferee. If
LICENSEE shall sell or otherwise transfer its entire business or that part of
its business to which the license granted hereby relates and the transferee
shall not have agreed in writing to be bound by the terms and conditions of this
Agreement, or new terms and conditions shall not have been agreed upon within
sixty (60) days of such sale or transfer, PRINCETON shall have the right to
terminate this Agreement.

                         ARTICLE XII - NON-USE OF NAMES

     12.1 LICENSEE shall not use the name PRINCETON nor any adaptation thereof
in any advertising, promotional or sales literature without prior written
consent obtained from PRINCETON, in each case, except that LICENSEE may state
that it is licensed by PRINCETON under one or more of the patents and/or
applications comprising the Patent Rights.



                                       13
<PAGE>

                         ARTICLE XIII - EXPORT CONTROLS

     13.1 It is understood that PRINCETON is subject to United States laws and
regulations controlling the export of technical data, computer software,
laboratory prototypes and other commodities (including the Arms Export Control
Act, as amended, and the Export Administration Act of 1979), and that its
obligations hereunder are contingent on compliance with applicable United States
export laws and regulations. The transfer of certain technical data and
commodities may require a license from the cognizant agency of the United States
Government and/or written assurances by LICENSEE that LICENSEE shall not export
data or commodities to certain foreign countries without prior approval of such
agency. PRINCETON neither represents that a license shall not be required nor
that, if required, it shall be issued.

            ARTICLE XIV - PAYMENTS, NOTICES AND OTHER COMMUNICATIONS

     14.1 Any payment, notice or other communication pursuant to this Agreement
shall be sufficiently made or given on the date of mailing if sent to such party

     AGREEMENT, made September 19, 1996, between CEDAR BROOK CORPORATE CENTER,
L.P., 1000 Eastpark Blvd., Cranbury, New Jersey 08512, "Landlord"; and TRANSCELL
TECHNOLOGIES, INC., 2000 Cornwall Rd., Monmouth Junction, NJ 08852, "Tenant".


                              W I T N E S S E T H :


     WHEREAS, the Landlord intends to lease to the Tenant a portion of 8 Cedar
Brook Drive, Cranbury, New Jersey 08512, constituting a portion of the
office/industrial park known as CEDAR BROOK CORPORATE CENTER ("Office Park");
and

     WHEREAS, the parties hereto wish to mutually define their rights, duties
and obligations in connection with the said lease;

     NOW THEREFORE, in consideration of the promises set forth herein, the
Landlord leases unto the Tenant and the Tenant rents from the Landlord the
Leased Premises described in Paragraph 1, and the Landlord and Tenant do hereby
mutually covenant and agree as follows:

     1.   LEASED PREMISES

     1.1 The leased premises shall consist of approximately 32,500 square feet,
measured from outside of glass to center line of common wall, but no less than
30,000 square feet; consisting of approximately 29,300 square feet of
laboratory/office space, plus 3,200 square feet of executive offices, all as
identified on the plan attached hereto and made a part hereof as Schedule "A",
("Leased Premises") together with all improvements to be constructed thereon by
the Landlord for the use of the Tenant, and all improvements, tenements,
hereditaments, fixtures and rights and privileges appurtenant thereto, and any
and all fixtures and equipment which are to be installed in said building by the
Landlord for the use of the Tenant in its occupancy of the Leased Premises and
any expansion phases. Tenant shall also have the right to use all common areas
of the Office Park in a similar manner as other Office Park tenants.


                                       4
<PAGE>


     1.2 Tenant shall have an option to expand the Leased Premises by renting
all, or a portion of the adjacent areas identified on Schedule "A" as Phases 2A
and 2B, in no less than 4,800 square foot increments (except for the final
increment which may be less), by providing Landlord with written notice within 2
years of the Commencement Date, as defined hereafter, and paying Landlord the
Reservation Fee set forth in Paragraph 4.1. If Tenant, at its option, leases all
or a portion of Phase 2, Tenant shall continue to pay the Reservation Fee for
any area of Phase 2 that it does not lease, for the remainder of the two year
period. If Tenant leases any of Phase 2B, then Tenant must either exercise its
option on Phase 2A no later than the end of the two year period or be obligated
to pay full rent for Phase 2A after the end of the 2 year period; provided,
however, if Tenant does not then construct improvements, it shall pay a reduced
rent for said expansion phase of $9.00 for an additional 12 months. Tenant shall
still be entitled to the $40.00 allowance referred to in Paragraph 3.1(d) when
and if it decides to construct improvements and shall pay rent at the rental
rate as shown in Paragraph 4.2 for Months 19-24 plus the sum of $0.55 per square
foot. If Tenant rents only a portion of Phase 2 during the 2 year option period,
the remaining portion of Phase 2 shall continue to be subject to the option for
the remaining balance of the 2 year period. In addition, if Tenant leases any
portion of Phase 2, it may elect to reserve a corresponding amount of space in
Phase 3, contiguous to Phase 2, and pay the $5/sq. ft. Reservation Fee as set
forth in Paragraph 4.2 for that space.

     1.3 In the event Tenant leases Phase 2, it shall have a second option to
lease any remaining portion of Phase 3 not then under reservation, by notifying
Landlord and paying the Reservation Fee for such remaining portion.

     1.4 In the event Tenant leases Phases 2 and 3, it shall have a further
option to lease Phase 4, which option shall be exercisable at any time during
the term of this Lease. Tenant shall provide Landlord with written notice
exercising its option and Landlord shall then have a period of up to 1 year
after notice to deliver said space to Tenant. If said space is leased to another
tenant, then Landlord shall pay the cost to relocate the other tenant. The
Tenant shall lease Phase 4 in its "as is", broom



                                       5
<PAGE>


clean condition, and at the then market rent for comparable space in the
vicinity; however, if the parties cannot agree, then standard appraisal methods
shall be used.

     1.5 To the extent that Tenant leases any of the expansion Phases, that
space shall be included within the definition of Leased Premises and be
coterminous with the term thereunder. Any construction work performed and/or
machinery, fixtures and equipment installed in the expansion Phases by Landlord
shall be included within the definition of Tenant Improvements as hereinafter
defined.

     2.   TERM OF LEASE

     The term of the Lease shall be 10 years, to commence on the "Commencement
Date" (as that term is hereinafter defined) and to end on the last day of the
month in which occurs the 10th anniversary of the Commencement Date. The term
"Commencement Date" shall mean the later of (x) April 1, 1997 or (y) the first
day of the next succeeding month following the occurrence of all of the
following conditions:

          (a) Landlord shall have achieved Substantial Completion (as that term
     is defined in Section 3.2 hereof);

          (b) All parking and Exterior areas of the Building shall be usable by
     Tenant;

          (c) All utilities to be furnished by Landlord shall be available to
     the Leased Premises; and
                  

          (d) Cranbury Township shall have issued a letter stating that Tenant's
     use is permitted in the zone.

     3.   CONSTRUCTION

     3.1 (a) Landlord shall complete the building shell in a competent and
workmanlike manner and in accordance with plans being prepared by The Kellner
Group, Architects and CEC, Inc., Structural Engineers ("Base Building Plans").
Landlord shall complete the construction of the Leased Premises in a competent
and workmanlike manner and in accordance with plans and specifications ("Plans")
to be prepared by Ewing Cole Cherry Brott, which Plans shall be in substantial
accordance with the specifications set forth in Schedule "B" and the Plans
attached as Schedule "C" which Plans may be amended from time to time by the
mutual agreement of both


                                       6
<PAGE>



parties. Landlord shall use its best efforts to achieve Substantial Completion,
as hereinafter defined, on or before May 1, 1997. Unless specifically revised by
both parties, Schedule "B" assumes the size of the laboratory/office space
portion of the Leased Premises to be 30,000 square feet and has been developed
based on the type and quality of work set forth in the Jacobs Wyper plans and
specifications for Phase 1 of 3000 Eastpark Blvd., Cranbury, NJ. The
improvements, machinery, fixtures and equipment to be constructed and installed
by Landlord, pursuant to this Paragraph 3, are hereafter referred to as the
"Tenant Improvements". In the event the number of square feet leased by Tenant
increases or decreases then the quantity of materials shall be adjusted. Said
Plans will be designed for a minimum area of 47,000 square feet of the building
so that the parties will know where Tenant's expansion is intended to occur in
the event it exercises its option to lease Phases 2A and 2B. Approximately
32,500 square feet will be designed completely, with the balance designed
schematically, including mechanical and electrical support rooms. Tenant shall
deliver to Landlord a complete set of Plans with which Landlord can obtain a
building permit by the later of 30 days after the completion of the erection of
the structural steel, or November 1, 1996. In the event that Tenant does not
meet these dates, Tenant shall be responsible to Landlord from that date for
monthly rent of $21,667 until Plans are delivered, prorated on a per diem basis.
The monthly rent shall accrue, but not be payable, provided the Plans are
delivered prior to February 1, 1997, and shall be paid by Tenant in a lump sum
on the Commencement Date. If the Plans are not delivered by February 1, 1997,
then Tenant shall, on that date, pay to Landlord all of the monthly rent that
has then accrued. Thereafter, Tenant shall pay the monthly rent of $21,667, in
arrears prorated as provided above, until it delivers the Plans to Landlord.

     Landlord has prepared the Base Building Plans and has provided Tenant with
the said Plans dated August 28, 1996 prepared by The Keller Group and the
preliminary/final site plan drawings dated June, 1996 prepared by Kupper
Associates and a list of building specifications as set forth in Schedule "D".
Landlord shall be responsible for the construction at its sole cost and expense
of the base building in conformance to the Base Building Plans. Landlord will
use reasonable efforts to keep 


                                       7
<PAGE>


Tenant advised of the progress of the building construction, and the approval of
same and of the Plans by the local governmental authorities, and will provide
Tenant with benchmark drawings and design parameters for the building. Tenant
shall notify Landlord of any changes it desires to make to the Base Building
Plans and shall bear all cost of such changes. In the event any change requested
by Tenant causes a delay in time, such delay shall extend Landlord's time to
perform hereunder.

     Tenant shall contribute toward the cost of construction of the Phase I
laboratory/office space, as defined in Schedule "A", the amount of $800,000. The
$800,000 shall be paid by Tenant upon Substantial Completion (as defined in
Paragraph 3.2) less 5% which shall be withheld until completion of the punch
items. Tenant shall also provide Landlord with an unconditional letter of credit
for $800,000 substantially in accordance with the form attached as Schedule "E"
within 30 days of execution of this Lease which will be promptly returned to
Tenant if it pays said sums as contemplated herein. Subject to Paragraph 3.1(b),
any cost over $800,000 shall be paid by Landlord. The $800,000 shall be adjusted
up or down based on the ratio of actual square footage of laboratory/office
space, excluding executive offices as referred to in Paragraph 1.1., leased to
the 30,000 square foot design standard for laboratory/office space. At Tenant's
request, Landlord will provide Tenant with documentation to support Tenant's
$800,000 contribution to the cost of Tenant Improvements.

     In addition, Landlord shall provide Tenant with an allowance for Tenant
Improvements for the executive offices of $50 per square foot, i.e., $50/sq. ft.
x 3200 sq. ft. = $160,000. Upon receipt of Plans from Tenant showing the
complete design of the executive offices, Landlord will provide, in writing,
within 10 business days, an estimated cost to construct the executive offices.
If such cost exceeds $50/sq. ft., then Tenant shall have the option, within 30
days after receipt of Landlord's estimate, to have its own professional
estimator or construction consultant confirm the per square foot price. If the
price is confirmed, then Tenant shall, still within said 30 day period, revise
the Plans to reduce the cost or advise Landlord to commence construction. If


                                       8
<PAGE>


Tenant's estimator or consultant feels that the per square foot price is too
high, then the parties shall negotiate in good faith to attempt to achieve a
cost of $50/sq. ft. 

     In determining the construction cost set forth above, for all authorized
deviations from Schedule B and costs in excess of the $50/sq. ft. allowance for
the executive offices and change orders referred to in Paragraph 3.1(c), the
actual cost charged by subcontractors, material suppliers and/or governmental
authorities shall be marked up for general conditions, overhead and profit as
set forth below: 

                 Billing Cost = Actual Cost x 1.02 x 1.08 x 1.05

     After the Plans are delivered by Tenant, any changes shall be governed by
Paragraph 3.1(c).

     (b) In the event Tenant or its architect adds to the scope, quantity or
quality of construction described in Schedule B, such additional cost up to a
maximum of $500,000, shall be paid by Tenant, through an increase in rent.
Tenant shall elect the method of paying the increase prior to the Commencement
Date of this Lease by choosing one of the following options:

          (i)  to fully amortize the increased cost over the first 5 years of
               the lease term, beginning from the Commencement Date, at the
               interest rate on the date of election of either 500 basis points
               over the 5 year Treasury bill rate or the Wall Street Journal
               published prime rate plus 3%; or

          (ii) to amortize the increased cost over the 10 year lease term,
               beginning from the Commencement Date, at the interest rate on the
               date of election of either 500 basis points over the 5 year
               Treasury bill rate or the Wall Street Journal published prime
               rate plus 3%, with a balloon payment of the total unamortized
               amount due at the end of the fifth lease year; 

If such additional cost exceeds $500,000, Tenant shall pay the amount in excess
of $500,000 within 10 days of the date billed by Landlord.


                                        9
<PAGE>


     (c) Any change orders that do not delay the Completion Date and that
increase or decrease the cost of the Tenant Improvements and that are desired by
Tenant after the Plans are delivered shall not be effective unless approved, in
writing, by both parties, and such approval by Landlord shall not be
unreasonably withheld or delayed and such cost shall be borne by Tenant and paid
for as set forth in Subparagraph 3.1(b);

     (d) In the event Tenant leases any of the expansion Phases, Landlord shall
be responsible for constructing the Tenant Improvements to said space provided
that Landlord has performed in substantial accordance with the construction
provisions set forth in this Lease, and the expansion Phases are not
specialized, scientific space not generally constructed by general contractors
experienced in laboratory construction. Tenant shall deliver the construction
plans for said space and Landlord agrees to develop a schedule and cost budget
for the expansion Phase and deliver same to Tenant within 15 business days after
receipt of the construction plans. Tenant, at its option, may accept such
schedule and budget or may use the services of a professional estimator or
construction consultant to review the schedule and cost budget with Landlord. If
Landlord and Tenant cannot agree, Landlord will be given 3 business days after
receipt of written notice from Tenant of the disagreement to match the schedule
and cost budget provided by Tenant's consultant. If Landlord chooses not to
accept the schedule and cost budget, Tenant shall competitively bid the project
using general contractors that have experience in the type of project being
undertaken. After such bids are received, Tenant shall provide them to Landlord
and Landlord shall have 5 business days after receipt to match the bid chosen by
Tenant. If Landlord elects to match said bid, it shall perform the construction
in accordance with the terms of the bid including reasonable timing and
guarantee terms. If Landlord is to perform said construction, the Reservation
Fee shall terminate in accordance with the terms of Paragraph 4.2 and rent shall
commence upon Substantial Completion in accordance with the terms of Paragraph
3.2. If Landlord does not match such bid, Tenant shall be free to accept the
outside bid. Landlord shall also have the right to approve the outside
contractor, which approval shall not be unreasonably withheld or delayed,
inspect the


                                       10
<PAGE>


work as it progresses and receive a fee of 2.5% of the total job cost. Rent
shall commence for said Phase, or part thereof, on the earlier of 6 months after
Tenant elects to retain the outside contractor, or occupancy, at which time the
Reservation Fee shall terminate. 

     Regardless of who performs the construction on the expansion Phases,
Landlord shall provide Tenant with an allowance for improvements of $40/sq. ft.
The actual cost of construction shall be paid by the Landlord and Tenant as
incurred relative to the amount by which the anticipated construction cost
exceeds $40.00 until Tenant's allowance of $40.00 per square foot has been fully
utilized. For example, if the anticipated construction cost is $120/sq. ft., the
construction costs shall be paid 1/3 by Landlord and 2/3 by Tenant on a monthly
basis until the Tenant allowance has been fully utilized. Thereafter, Tenant
shall be responsible for the full payment of all construction costs. Tenant's
Architect shall certify to Landlord that the construction for which Tenant seeks
payment has been completed. If actual costs are less than the anticipated
construction costs, then at the conclusion of construction, Landlord shall pay
Tenant any unpaid balance of the $40.00 allowance. If Landlord does not pay all
or part of the $40.00 allowance, within 60 days of the date Landlord receives an
invoice, Tenant may offset said amount against rent. Said costs shall include
actual fees for consultants, contractors, subcontractors, material suppliers and
governmental authorities, and the installed cost and related construction costs
of all of the tenant improvements shown on the expansion plans, including but
not limited to such items as trash removal related to tenant improvements.

     If Landlord is to construct the expansion Phases, representatives of each
party shall inspect the site no less frequently than every 2 weeks and verify
and agree that work has been completed in a manner acceptable to both Landlord
and Tenant. Landlord will then prepare an invoice for work completed (less
Landlord's proportionate share), and Tenant shall pay the same within 10
business days of receipt. Landlord shall be responsible for paying $40/sq. ft.
for Tenant Improvements to the expansion Phases and Tenant shall bear the
balance of the cost. For example, if the cost is determined to be $137/sq. ft.,
Landlord shall pay $40 and Tenant shall pay $97. In 

                                       11
<PAGE>


the event the payment is not received by Landlord within the specified time,
interest shall accrue on the unpaid balance at an interest rate of 1% per month.

     (e) During construction of the Leased Premises or any expansion Phases,
Tenant shall have access in order to install its own equipment provided:

          (i) it delivers to Landlord a certificate of insurance for the
     coverage set forth in Paragraph 8.5; and

          (ii) it shall coordinate its work with the work being performed by
     Landlord so that there shall be no unreasonable interference with, delay or
     interruption of, Landlord's work.

     (f) All construction of expansion Phases by Landlord shall be done in a
competent and workmanlike manner, in accordance with Tenant's plans and
specifications and the cost and timing schedule agreed to by Landlord. At
Tenant's request, Landlord will provide Tenant with documentation to support
Tenant's $800,000 contribution to the cost of Tenant Improvements.

     3.2 The Leased Premises and any expansion Phases, if constructed by
Landlord, shall be considered substantially completed, and rent payments shall
commence, upon the issuance of a Temporary or Permanent Certificate of
Occupancy, or a Temporary or Permanent Certificate of Acceptance ("CO/CA")
provided that any Temporary CO/CA is not revoked or does not limit Tenant's use
and is promptly followed by a Permanent CO/CA; and when the machinery, equipment
and fixtures to be installed by Landlord are operable so that Tenant can conduct
its customary business activities ("Substantial Completion") but for the initial
Leased Premises, not before April 1, 1997. It is agreed that for the purpose of
this Lease, wherever and whenever the term Substantial Completion is used, it
shall not include items of maintenance, service or guarantee. Within 30 days
after occupancy, Tenant will provide Landlord with a punch list of items to be
corrected which will be completed by Landlord within 60 days of receipt of the
punch list. Tenant and Landlord shall execute a confirmation of Lease
Commencement Date in the form of Schedule "F". If the 


                                       12
<PAGE>


Commencement Date occurs on a day other than the first day of a month, rent from
such day until the first day of the following month shall be prorated (at a rate
of 1/30th of the monthly rent per day). During said period of partial monthly
occupancy, all other terms and conditions of this Lease shall apply.

     3.3 andlord acknowledges and agrees that Tenant will suffer financial loss,
the exact extent of which is difficult to determine, if the Leased Premises are
not Substantially Completed by May 1, 1997 subject to extension for Tenant's
failure to deliver Plans in a timely manner as set forth in Paragraph 3.1(a) and
Paragraph 22, Force Majeure. In connection with the foregoing, if the Tenant
Improvements are not Substantially Completed by June 1, 1997, Landlord shall be
liable for and shall promptly pay to Tenant at the end of the month, as
Stipulated, Fixed, Agreed Upon and Liquidated Damages (and not as a penalty)
$20,000. If the Leased Premises are not Substantially Completed on or before
July 1, 1997, Landlord shall promptly pay to Tenant, on July 3, 1997 and at the
end of each month thereafter, an additional $30,000 for each month or prorated
portion thereof that the Tenant Improvements are not Substantially Complete.
Said monthly sum of $30,000 shall continue to be paid by Landlord until October
1, 1997. After November 15, 1997, Tenant shall have the right to terminate this
Lease if Substantial Completion has not been achieved. Upon termination,
Landlord shall promptly return to the Tenant, the letter of credit referred to
in Paragraph 3.1(a).

     3.4 The Landlord shall have the right to substitute for the materials and
equipment required by the Plans, materials and equipment of equal quality and
standard, provided said substitutions are requested in writing and conform with
applicable building codes and Tenant or its designee has consented in writing to
the substitution, which consent shall not be unreasonably withheld or delayed.
If Tenant does not reply to Landlord within 3 business days, it shall be
determined to have approved the change.

     3.5 With regard to the initial Leased Premises, Landlord shall, within 10
days of date Tenant requests, waive, in writing, all rights or liens on Tenant's
equipment, such as analytical and synthesis instruments, portable cold rooms,


                                       13
<PAGE>


refrigerators, freezers, items mounted on bench tops and any equipment which is
bolted to the structure or walls for added stability, which Tenant has leased.
With regard to the expansion Phases, Landlord agrees to, within 10 days of date
Tenant requests, waive, in writing, all rights or liens on Tenant's equipment or
trade fixtures such as fume hoods, case work, refrigerators, freezers, biosafety
cabinets, analytical and synthesis instruments, items mounted on bench tops and
any equipment which is bolted to the structure or walls for added stability
which Tenant has leased. The waiver shall not apply to any building improvements
made by, or on behalf of Tenant, such as permanently installed cold rooms, HVAC
equipment and ducts, plumbing, electrical or units related thereto.

     4. RENT

     4.1 The Original Base Rent for the Leased Premises shall be calculated
based on the following annual rates per square foot:

================================================================================

Years      Laboratory/Office      Executive Office     Phase 2 (if not occupied)

 1-5             27.30                  16.75            5.00* for 2 years only

6-10             28.00                  18.43                    -------

================================================================================
     *This sum shall include common area maintenance and real estate taxes.

     In the event Tenant occupies the 32,500 square feet contemplated at the
execution of this Lease, the rent on the Commencement Date shall be:

     29,300 sq. ft. laboratory/office                     $799,890
      3,200 sq. ft. executive office                        53,600
     14,510 sq. ft. Phase 2 (Reservation Fee)               72,550
                                                          --------
                                                          $926,040

payable in equal monthly installments in the sum of $77,170. In the event the
actual space occupied at the Commencement Date varies from 32,500 square feet,
the rent shall be adjusted based on the rental rates per square foot set forth
above.

     4.2 Unless a third party performs the construction, the $5/sq. ft. rent
("Reservation Fee") for Phase 2, or part thereof, and Phase 3, or part thereof,
if 


                                       14
<PAGE>


applicable pursuant to Paragraph 1.2, shall continue until (i) 30 days after
Tenant gives written notice that it is cancelling its option to lease such
space; (ii) the receipt by Landlord from Tenant of notice that it has chosen
Landlord to perform the construction and permittable construction documents for
the Phase to be constructed; or (iii) the expiration of the two year period.
However, if Tenant stops paying the Reservation Fee, it shall still have the
Right of First Refusal set forth in Paragraph 42 for Phase 2, or part thereof,
for an additional number of months equal to the number of months that it had
paid the Reservation Fee. Except as provided in Paragraph 42.4, in the event
Tenant leases any or all of Phase 2, the annual rent per square foot shall be as
set forth in the table below, pro rated for a partial month, and such rent shall
be added to the Original Base Rent.

</TABLE>


Except as provided in Paragraph 42.4, the rental rate for Phase 3, or part
thereof, shall be as set forth above for Phase 2, Months 19-24, increased by 2%
annually until the commencement date of Phase 3, or part thereof. The $40/sq.
ft. tenant allowance shall also be increased annually by 2%.

     4.3 Rental payments shall be made promptly in advance on the first day of
each and every month during the term of the Lease without demand and without
off-set or deduction, except as otherwise set forth herein or if Tenant obtains
a money judgment against Landlord, together with such additional rent and other
charges required to be paid by Tenant as are hereinafter set forth, all of which
charges shall be considered additional rent. Tenant shall pay as additional
rent, the amounts required in Paragraph 8. If any amount due to Tenant pursuant


                                       15
<PAGE>


to Paragraph 3.3 is not paid within 30 days of the date due, Tenant shall have
the right to set off said sum against any rent due hereunder.

     5. PARKING AND USE OF EXTERIOR AREA

     The Tenant shall have the right to use the parking spaces for their
employees and visitors on a non-exclusive basis in common with other tenants of
the building. Landlord will provide 4 visitor and 2 reserved signs for Tenant to
use, but shall not monitor parking in the spaces. The Landlord and Tenant
mutually agree that they will not block, hinder or otherwise obstruct the access
driveways and parking areas so as to impede the free flow of vehicular traffic
on the property. If Tenant leases the expansion Phases, additional visitor and
reserved signs will be provided in reasonable proportion to the additional space
leased. In connection with the use of the loading platforms, if any, Tenant
agrees that it will not use the same so as to unreasonably interfere with the
use of the access driveways and parking areas. Tenant shall not store trailers
or other vehicles on any portion of the access driveways or parking areas, and
may not utilize any portion of the land outside of the Leased Premises for any
purpose unless consented to in advance by Landlord.

     6. USE

     The Tenant covenants and agrees to use and occupy the Leased Premises for
office, general laboratory, manufacturing, marketing, pharmaceutical and
bio-technical research and development, or any combination of the foregoing,
which uses are expressly subject to all applicable zoning ordinances, rules and
regulations of any governmental instrumentalities, boards or bureaus having
jurisdiction thereof. Prior to Substantial Completion of Leased Premises,
Landlord will obtain and deliver to Tenant a letter from the Township that the
Tenant's initial use of the building is permitted under the Township ordinances.
Landlord represents that there are no recorded documents that would prevent
Tenant's contemplated use of the Leased Premises.

     7. REPAIRS AND MAINTENANCE


                                       16
<PAGE>


     7.1 (a) Subject to Paragraph 7.1(b), Tenant shall generally maintain and
repair the Leased Premises in a good and workmanlike manner, and shall, at the
expiration of the term, deliver the Leased Premises in good order and condition,
damages by fire or casualty, whether or not Tenant has been negligent, the
elements or other causes outside the control of Tenant and ordinary wear and
tear excepted. Tenant covenants and agrees that, subject to Paragraph 8.6
hereof, it shall not cause or permit any waste, damage or disfigurement to the
Leased Premises, or permit the load factor on the slab on grade to exceed 150
p.s.i. The Tenant shall make all repairs to the floor surface, the electrical
and plumbing systems located within the Leased Premises, both above and below
the floor, including all ballasts and fluorescent fixtures and HVAC system,
unless the repair is the result of the negligence of Landlord, its agents,
contractors, employees, tenants or invitees.

     (b) Landlord shall assign to Tenant all manufacturer's warranties for
Tenant Improvements and Tenant agrees to rely on said warranties in the event of
any problem with such covered items. Notwithstanding the foregoing, in the event
any Tenant Improvements installed or constructed by Landlord are not covered by
a warranty or the party providing the warranty does not adequately respond, then
Landlord shall guarantee the proper operation and performance of those Tenant
Improvements for a period of one year after Substantial Completion of the
applicable work, except for items of normal maintenance and provided that the
problem was not caused by Tenant's negligence, lack of maintenance or incorrect
maintenance. For the first 60 days after Substantial Completion, the Landlord
will perform all routine maintenance on the HVAC System. Landlord shall be
responsible for good and workmanlike repairs and replacements necessary to the
roof, foundation, exterior and load-bearing walls and other structural elements,
and electric, plumbing and other building systems to the point where they enter
the Leased Premises, unless, and to the extent the repair is necessitated by the
negligence of Tenant or its agents, 


                                       17
<PAGE>


and the cost thereof is not covered by Landlord's insurance, or the insurance
Landlord is required to carry under this Lease, (without taking into account any
deductible) whichever is greater. Repairs and replacements shall be made within
a reasonable time after Landlord receives notice or has actual knowledge of the
need for such repair or replacement.

     7.2 The Tenant shall, at its own cost and expense, pay all utility meter
and service charges for utilities used by Tenant in the Leased Premises,
including gas and electric servicing its space. Landlord shall have the option
to install, at its own cost, a separate water meter in order to monitor Tenant's
water usage. The Tenant agrees to maintain all leased areas at a minimum
temperature of 45 degrees F, excluding cold rooms or other rooms designated for
a lower temperature, to prevent the freezing of domestic water and sprinkler
pipes provided Tenant shall not be liable if gas or electrical service to the
Building has been interrupted for a reason not caused by Tenant. Tenant shall
not store any garbage or recyclables outside the Leased Premises, and shall
deliver its garbage and recyclables to the central receiving area on the lot.


     7.3 Landlord shall provide the following during the term of this Lease:

          (a) Continually cooperate with Public Service Electric and Gas to have
     Public Service Electric and Gas provide gas and electrical service to the
     point where it enters the Leased Premises for Tenant's permitted uses, as
     specified in the Plans approved by Public Service Electric & Gas;

          (b) Extermination and pest control when necessary;

          (c) 24-hour access to the Leased Premises;

          (d) Water facilities to the point where they enter the Leased Premises
     for lavatory, drinking and cleaning purposes; and

          (e) Maintenance of the common areas of the Office Park, in a manner
     similar to other office parks in the area, with the cost to be passed on to
     Tenant as set forth in Paragraph 8.

     7.4 Landlord does not warrant that any services Landlord or any public
utilities supply will not be interrupted. Services may be interrupted because of
accidents, repairs, alterations, improvements or any other reason beyond the
reasonable control of Landlord. Notwithstanding the foregoing, if any essential
services (such as access, electricity or water) supplied to the Leased Premises
are interrupted, or if Landlord fails to make any repairs or replacements it is
required under this Lease to make and that are necessary to enable Tenant and
its employees, invitees and agents to use the Leased Premises without material
interference, then Tenant shall be entitled to an abatement of rent and
additional rent. The abatement shall begin on the seventh consecutive business
day of the interruption or interference, or when Tenant stops using the Leased
Premises because of the interruption or interference, whichever is later. The
abatement shall end when the services are restored or the repairs or
replacements are made or installed. Tenant shall have the option to cancel this
Lease without penalty if the interruption or failure to repair or replace
unreasonably interferes with Tenant's use of or access to the Leased Premises
for at least thirty (30) consecutive days, and Landlord is not exercising its
best efforts to restore the services or make the repair or replacement.

                        connection with any equity or debt financing or sale of

                  (xi)  Costs of specialized services or other items provided to
                        other tenants but not provided to tenants generally;

                                       21
<PAGE>


                        incurred in leasing items ordinarily considered to be of
                        a capital nature;

                 (xiii) Cost to comply with ADA related to the interior of the
                        individual buildings, but not exterior doors or the cost
                        of improvements required by ADA to the Office Park

          (c) The $1.50/sq. ft. for Common Area Expenses shall be increased 2%
     for each year of the Lease Term on January 1st each year. At the end of
     each 5 years of the Lease Term, the per square foot charge shall be
     adjusted for the next 5 year period to reflect the actual increase in the
     CPI, as defined hereafter, over the prior 5 year period. The parties also
     agree to adjust any individual expense item in Paragraph 8.1(a) which has
     an unusual cost or usage, or an unusual increase or decrease during any
     year.

     8.2 The Tenant shall pay its proportionate share of real estate and
personal property taxes assessed against the land, building shell and site
improvements, along with any levy for the installation of improvements serving
the Leased Premises assessed by any governmental body having jurisdiction
thereof but excluding any special assessments caused by the use of the building
by other tenants. The real estate tax obligation of the Tenant shall include any
tax or imposition for parking lot usage which may be levied by any governmental
body having jurisdiction thereof. Tenant's proportionate share shall be a
percentage derived by dividing the total square feet leased by Tenant by the
total square feet in the building. In addition to its proportionate share of the
above items, Tenant shall pay all real estate taxes assessed by the municipality
on its Tenant improvements. Tenant shall have the right to contest, or cause
Landlord to contest, the assessed value of the building, land and improvements
or the real 


                                       22
<PAGE>


estate or personal property taxes and Landlord agrees to provide any and all
documentation reasonably required for Tenant to contest said assessment. Tenant
shall pay all reasonable costs of Landlord in the event Landlord is required to
contest. Landlord is currently not aware of any abatement or deferral program in
connection with the Leased Premises. If taxes are abated or deferred as a result
of an appeal, or under any other program, Tenant shall gain the benefit of such
reduction. Notwithstanding the foregoing, Tenant shall not be required to
reimburse Landlord for any capital stock, income, franchise, estate,
inheritance, gift or transfer taxes, or any penalties or interest for failure to
pay in a timely manner.

     8.3 Tenant shall pay its share of Common Area Expenses monthly together
with the rent except for taxes which shall be billed and paid quarterly.
Tenant's Share of Common Area Expenses and real estate taxes for any calendar
year, part of which falls within the term of this Lease and part of which does
not, shall be appropriately prorated.

     8.4 If at any time during the term of this Lease the method or scope of
taxation prevailing at the commencement of the Lease Term shall be altered,
Tenant's proportionate share of such substituted tax or imposition if it relates
to Tenant's occupancy, shall be payable and discharged by the Tenant in the
manner required pursuant to the law which shall authorize such change.

     8.5 (a) The Tenant covenants and agrees that it will, at its sole cost and
expense, carry liability insurance covering the Leased Premises in the minimum
amount of $1,000,000.00 per accident for 1 person, $3,000,000.00 per accident
for 2 or more persons, and a minimum amount of $300,000.00 for property damage
with Landlord listed as an insured party;

     (b) Landlord shall keep the base building of which the Leased Premises are
a part, including without limitation, all fixtures (but not Tenant Improvements)
insured against damage and destruction by fire, sprinkler damage, vandalism,
comprehensive liability and other perils in the amount of the 


                                       23
<PAGE>


full replacement value of such building, as the value may exist from time to
time, including insurance for one year's rent, with a deductible of no more than
$10,000 except that Landlord will be responsible for any deductible amount over
that sum. The insurance shall include an extended coverage endorsement of the
kind required by an institutional lender to repair and restore such base
building. Any increase in the insurance premiums due to a change in rating of
the base building which is solely attributable to Tenant's use, or due to
special Tenant equipment, shall be paid entirely by the Tenant. During
construction, Landlord will increase the amount of insurance coverage by
$800,000 to cover Tenant's contribution to Tenant Improvements, with the
additional premium cost thereof to be borne by Tenant.

     With regard to each expansion Phase, Tenant shall certify to Landlord, at
the completion of construction, the cost of the improvements made to that Phase
and Landlord shall, after receipt of the certification, increase the amount of
insurance coverage by said amount, with the additional premium cost thereof to
be borne by Tenant;

     (c) The insurance policies referred to above shall be maintained by
insurance companies licensed to do business in the State of New Jersey, with a
general policyholder's rating of at least A and a financial rating of at least
XI in Best's Insurance Reports. If such ratings are changed or discontinued, the
parties shall agree to an alternate method of rating insurance companies. Such
policies shall be maintained throughout this Lease, including any extensions.
Each party shall deliver a certificate of insurance to the other evidencing this
insurance. Such certificate shall provide that the policy shall not be cancelled
or the coverage will not be materially reduced without 10 days prior written
notice.

     8.6 The parties covenant and agree that the insurance policies required to
be furnished in accordance with the terms and conditions of this Lease, or in
connection with insurance policies which they obtain insuring such 


                                       24
<PAGE>


insurable interest as Landlord or Tenant may have in its own properties, whether
personal or real, shall expressly waive any right of subrogation on the part of
the insurer against the Landlord or Tenant. Notwithstanding anything to the
contrary, Landlord and Tenant each mutually waive all right of recovery against
each other, their agents, or employees for any loss, damage or injury of any
nature whatsoever to property or person (regardless of whether the party in
whose favor the waiver applies was negligent) for which either party is required
by this lease to carry insurance.

     90 SIGNS

     At its sole expense the Tenant shall have the right to install no more than
2 signs, including exterior ground signs at the Leased Premises, subject to
Landlord's approval, which shall not be unreasonably withheld or delayed. The
signs shall comply with the rules and regulations of the applicable governmental
boards and bureaus having jurisdiction thereof. The installation of such signs
shall not cause any structural damage to the building and shall not be permitted
on the roof. Landlord shall provide a monument sign near the entrance to the
building listing all of the tenants occupying space in the building, with
Tenant's name at the top.

     100 ASSIGNMENT AND SUBLETTING

     10.1 The Tenant may not assign or sublet the Leased Premises or any part
thereof, without the consent of Landlord, which shall not be unreasonably
withheld or delayed. Tenant shall have absolutely no right to assign or sublet
any expansion Phases unless Tenant is paying the full rent due thereon. If
Tenant desires to assign or sublet, it shall first give to Landlord notice in
writing. Landlord shall have 14 calendar days from receipt of such notice to
elect to consent to the assignment of the Lease or the sublease of the Leased
Premises. If Landlord fails to respond in the 14 day period, consent is deemed


                                       25
<PAGE>


given. However, Tenant shall be permitted to assign this Lease or sublease the
premises, without the consent of Landlord but with notice to Landlord, to (i) a
wholly owned subsidiary, or a parent, (ii) any corporation, partnership, trust,
limited liability company or similar entity controlling, under the direct or
indirect control of Tenant or under common control with Tenant (collectively,
"Tenants Affiliates"), (iii) any corporation resulting from the merger or
consolidation with Tenant or that acquires all of Tenant's assets or stock; (iv)
any joint venture or similar arrangement as to which Tenant or Tenant's
Affiliates are a party; or (v) a Tenant whose use is specifically permitted
under this Lease.

     10.2 In the event of any assignment or subletting permitted by the
Landlord, the Tenant and Guarantor, as set forth in a separate Guaranty, shall
remain and be directly and primarily responsible for payment and performance of
the within Lease obligations, and the Landlord reserves the right, at all times,
to require and demand that the Tenant pay and perform the terms and conditions
of this Lease. No such assignment or subletting shall be made to any tenant who
shall occupy the Leased Premises for any use other than that which is permitted
to the Tenant.

     110 FIRE AND CASUALTY

     11.1 If there occurs any damage to or destruction of any portion of the
building of which the Leased Premises is a part by fire or other casualty
occurring during the term of this Lease, which shall render at least 1/3 of the
floor area of the Leased Premises untenantable or unfit for occupancy, and
either party reasonably determines within 30 days of the casualty that the
Leased Premises cannot be repaired within 240 days from the happening of such
casualty, using reasonable diligence ("Total Destruction") then the Lease shall,
at the option of the Landlord or Tenant, upon written notice to the other within
a further 15 days, cease and become null and void from the date of such Total
Destruction. In such event the Tenant shall immediately surrender the Leased
Premises to the Landlord and this Lease shall terminate. The Tenant shall only
pay rent to the 


                                       26
<PAGE>


time of such Total Destruction. However, in the event of Total Destruction if
the Landlord and Tenant shall elect not to cancel this Lease within the 15 day
period the Landlord shall repair and restore the building, Leased Premises and
all Tenant Improvements to substantially the condition they were in prior to the
damage or destruction, with deliberate speed and dispatch. The rent shall not be
accrued after said damage or while the repairs and restorations are being made,
but shall recommence immediately after the Leased Premises are so restored as
evidenced by the issuance of a CO/CA by municipal authorities and that any
machinery, equipment and/or fixtures Landlord was responsible for installing are
operable so as not to materially interfere with the customary business
activities of Tenant. Notwithstanding the foregoing, if any such restoration is
not completed within 365 days of such Total Destruction, Tenant may terminate
this Lease without penalty.

     11.2 In the event of any other casualty which shall not be tantamount to
Total Destruction the Landlord shall promptly repair and restore the Building,
the Leased Premises and the Tenant Improvements, subject to availability of
insurance proceeds, to substantially the same condition as they were prior to
the damage or destruction, with reasonable speed and dispatch. The rent shall
abate or be equitably apportioned from the date of casualty to the extent the
Tenant's use is impaired. Landlord shall have the right to not make the repairs,
if it has complied with Paragraph 8.5(b) but cannot confirm the availability of
insurance proceeds within 90 days of the casualty. In such event, Landlord will
notify Tenant within said 90 day period that it cannot confirm the insurance
proceeds and is electing not to make the repairs. Tenant shall have 10 business
days from receipt of said notice to elect whether to terminate the lease. If
Landlord does make the repairs, the rent shall recommence immediately upon
restoration of the Leased Premises as evidenced by the issuance of a CO/CA by
municipal authorities and any machinery, equipment and/or fixtures Landlord was
responsible for installing are operable so as not to materially interfere with
the 


                                       27
<PAGE>


customary business activities of Tenant. Notwithstanding the foregoing, if any
such restoration is not completed within 365 days of such casualty, Tenant may
terminate this Lease without penalty.

     11.3 In the event the Landlord rebuilds, the Tenant agrees, at its cost and
expense, to forthwith remove any and all of its equipment, fixtures, and
personal property in order to permit Landlord to expedite the construction. The
Tenant shall assume at its sole risk the responsibility for damage to or
security of such fixtures and equipment that it does not move in the event that
any portion of the building area has been damaged and is not secure provided
Landlord has not been grossly negligent subsequent to the casualty. However,
nothing shall preclude Tenant from making a claim to any insurance company for
the cost of such removal.

     120 COMPLIANCE WITH LAWS, RULES AND REGULATIONS

     12.1 (a) The Tenant agrees that upon acceptance and occupancy of the Leased
Premises, it will promptly, at its own cost and expense, comply with all
statutes, ordinances, rules, orders, regulations and requirements of the
Federal, State and Municipal governments ("Applicable Laws") relating to the
manner in which Tenant uses the Leased Premises. The Tenant also agrees that it
will not commit any nuisance, and will dispose of all garbage and waste in
compliance with law and Landlord's reasonable written rules and regulations.
Landlord warrants that on the date this Lease commences, the Leased Premises and
the building of which it is a part will comply with all Applicable Laws.
Notwithstanding anything to the contrary, in no case shall Tenant be required to
comply with Applicable Laws with regard to any structural component or building
system that is Landlord's responsibility pursuant to Paragraph 7.1. Landlord
will comply with all applicable laws with regard to the building shell, core
site and building systems that are not the responsibility of the Tenant.

     (b) The Tenant agrees, at its own cost and expense, to comply with such
regulations or requests as may be required by the fire or 


                                       28
<PAGE>


liability insurance carriers providing insurance for the Leased Premises in
connection with Tenant's use and occupancy of the Leased Premises. If such
regulations or requests are arbitrary and capricious then Tenant shall have the
right to require Landlord to obtain insurance from another company.

     12.2 In case the Tenant shall fail to comply with all material provisions
of the aforesaid statutes, ordinances, rules, orders, regulations and
requirements with which Tenant is required under the terms of this Lease to
comply, then the Landlord may, after 30 days' notice (except for emergency
repairs, which may be made immediately), and provided that Tenant has failed to
take such reasonable action to investigate or remedy the reason for
noncompliance, enter the Leased Premises and take any reasonable actions to
correct any noncompliance, at the cost and expense of the Tenant. The cost
thereof shall be added to the next month's rent and shall be due and payable as
such, or the Landlord may deduct the same from the balance of any sum remaining
in the Landlord's hands. This provision is in addition to the right of the
Landlord to terminate this Lease pursuant to Section 14.2. However, in the event
that Tenant is proceeding with any investigation or repairs to ensure compliance
with the aforesaid laws and regulations, the initial failure to comply with the
aforesaid laws and regulations shall not constitute an event of default.

     12.3 Tenant expressly covenants and agrees to indemnify, defend and save
the Landlord harmless against any claim, damage, liability, cost, penalties, or
fines which the Landlord may suffer as a result of air, ground or water
pollution which requires remediation under any Environmental Law and is caused
by the Tenant, its agents and contractors, in its use of the Leased Premises.
Landlord shall indemnify, defend and save the Tenant harmless against any claim,
damage, liability, cost, penalties, or fines which the Tenant may suffer as a
result of air, ground or water pollution which requires remediation under any
Environmental Law and is caused by Landlord, its agents and contractors. The
Tenant covenants and agrees to provide the Landlord with 


                                       29
<PAGE>


reasonable notice of any claim or notice served upon it with respect to any
claim that the Tenant is causing air, ground or water pollution in violation of
an Environmental Law; and the Tenant shall take prompt and reasonable steps to
halt, remedy or cure any pollution of air, ground or water which requires
remediation under an Environmental Law and is caused by the Tenant by its use of
the Leased Premises.

     12.4 Tenant expressly covenants and agrees to fully comply with the
provisions of the New Jersey Industrial Site Recovery Act (N.J.S.A. 13:1K-6, et
seq.) "ISRA", and its regulations to the extent applicable, prior to the
termination of the Lease.
 
          (a) The term "evidence of compliance", as used herein, shall mean a
     "letter of non-applicability" issued by the New Jersey Department of
     Environmental Protection ("NJDEP"), or an approved "negative declaration"
     or a "remediation action plan" which has been submitted to the NJDEP for
     approval.

          (b) In the event ISRA is applicable and (a) evidence of Tenant's
     compliance is not delivered to the Landlord and (b) Tenant has not
     attempted to secure evidence from the NJDEP, it is understood and agreed
     that Tenant shall be liable to pay to Landlord an amount equal to two times
     the Monthly Base Rent then in effect, together with all applicable
     additional rent from the date of such surrender until such time as evidence
     of compliance with ISRA has been delivered to the Landlord, and together
     with any costs and expenses incurred by Landlord in enforcing Tenant's
     obligations under this paragraph. Evidence of compliance shall be delivered
     to Landlord, together with all copies of all submissions made to the NJDEP,
     including all environmental reports, validated test results and other
     relevant supporting documentation.

          (c) Tenant shall only be liable to Landlord for regular rent and not
     for double rent as set forth above, if (i) Tenant has submitted all
     documentation initially required by NJDEP to obtain evidence of compliance
     at least 6 months before the expiration of the Lease term and Tenant is
     unable to 


                                       30
<PAGE>


     obtain such evidence prior to the expiration of the Lease term, and (ii)
     Landlord is unable to either refinance or relet the Leased Premises solely
     as a result of Tenant's failure to obtain evidence of compliance.
     Notwithstanding anything to the contrary, it is understood and expressly
     agreed by Landlord and Tenant that Tenant shall not be required to comply
     with the time limits to submit evidence of compliance if the Lease is
     terminated prior to the scheduled expiration of the term of the Lease as a
     result of a reason which is beyond the control of the Tenant, such as a
     casualty or condemnation. In such event, Tenant shall not be liable for any
     rent so long as Tenant diligently attempts to obtain such evidence of
     compliance.

          (d) In the event ISRA is applicable to any other portion of the Office
     Park not under the operation and control of Tenant and Landlord is required
     to apply to the NJDEP for a letter of non-applicability, negative
     declaration or remediation plan, Tenant agrees that it shall fully
     cooperate with Landlord in connection with any information or documentation
     which may be requested of Tenant by the NJDEP, provided Landlord pays all
     Tenant's reasonable expenses and cost thereof. If, in the course of
     Landlord's application, any remediation of the Office Park is required
     which is directly attributable to Tenant's operation of the Leased
     Premises, Tenant expressly covenants and agrees that it shall be
     responsible for only that portion of the remediation which is directly
     attributable to its operation. It is understood and expressly agreed by
     Landlord and Tenant that Tenant shall not be responsible for any rent
     beyond the Lease term as provided for in Paragraph 12(b) or 12(c) if ISRA
     is applicable to a portion of the Office Park not under the operation and
     control of Tenant.

     140 DEFAULT BY TENANT

     14.1 Each of the following shall be deemed a default ( an "Event of
Default") by Tenant and a breach of this lease:

          (a)  (i)  filing of a petition by the Tenant for adjudication as a
                    bankrupt, or for reorganization, or for an arrangement under
                    any federal or state statute, except in a Chapter 11
                    Bankruptcy where the rent and additional rent stipulated
                    herein is being paid and the terms of the lease are being
                    complied with;

               (ii) dissolution or liquidation of the Tenant;

              (iii) appointment of a permanent receiver or a permanent trustee
                    of all or substantially all of the property of the Tenant,
                    if such appointment shall not be vacated or stayed within 90
                    days, provided the rent and additional rent stipulated
                    herein is being paid and the terms of the lease are being
                    complied with, during said 90 day period;

               (iv) taking possession of the property of the Tenant by a
                    governmental officer or agency pursuant to statutory
                    authority for dissolution, rehabilitation, reorganization or
                    liquidation of the Tenant if such taking of possession shall
                    not be vacated or stayed within 90 days, provided the rent
                    and additional rent stipulated herein is being paid and the
                    terms of the lease are being complied with, during said 90
                    day period;

               (v)  making by the Tenant of an assignment for the benefit of
                    creditors.

          (b) Default in the payment of the rent or additional rent herein
     reserved or any part thereof, when due, which continues for 10 days after
     notice from Landlord of such default. However, if Tenant is more than 10
     days late, twice in any 12 month period, then the 10 day period is reduced
     to 5 days upon notice to Tenant; and written notice shall no longer be
     required from Landlord during such 12 month period.

          (c) A default in the performance of any other covenant or condition of
     this lease on the part of the Tenant to be performed for a period of 30
     days after notice. However, no default on the part of Tenant shall be
     deemed 


                                       33
<PAGE>


     to exist if it diligently commences efforts to rectify same within such 30
     day period.

     14.2 Upon any Event of Default set forth above and lapse of applicable
grace period, Landlord may serve written notice upon the Tenant with a copy to
the guarantor, if any, electing to terminate this lease upon a specified date
not less than 10 days after the date of serving such notice and this Lease shall
then expire on the date so specified as if that date had been originally fixed
as the expiration date of the term herein granted. However, an Event of Default
shall be deemed waived if such default is made good before the date specified
for termination in the notice of termination served on the Tenant. 14.3 In case
this Lease shall be terminated Landlord or its agents may, immediately or any
time thereafter, re-enter and resume possession of the Leased Premises or such
part thereof, and remove all persons and property therefrom, either by summary
proceedings or by a suitable action or proceeding at law, without being liable
for any damages therefor. No re-entry by Landlord shall be deemed an acceptance
of a surrender of this lease. However, if an Event of Default has occurred and
Tenant moves out, or is dispossessed, and fails to remove any of its property,
machinery, equipment and fixtures or other property within 10 days after such
default, dispossess or removal, then and in that event, the said property,
machinery, equipment and fixtures or other property shall at the option of the
Landlord, be deemed to be abandoned, or the Landlord may remove such property
and charge the reasonable cost and expense of removal and storage to the Tenant.
The Tenant shall be liable for any damage which it causes in the removal of said
property from the Leased Premises.

     14.4 In case this Lease shall be terminated Landlord may, relet the whole
or any portion of the Leased Premises, for any period equal to or greater or
less than the remainder of the then current term, for any sum which it
reasonably may deem appropriate, to any tenant which it may reasonably deem
suitable and satisfactory, and for any use and purpose which it may deem
appropriate. In 


                                       34
<PAGE>


connection with any such lease, Landlord may make such changes in the character
of the improvements on the Leased Premises as Landlord may reasonably determine
to be appropriate or helpful in effecting such lease and may grant concessions
or free rent to the extent commercially reasonable. Landlord shall make
reasonable efforts to relet the Leased Premises. Landlord shall not in any event
be required to pay Tenant any sums received by Landlord on a reletting of the
Leased Premises, but this shall not effect Landlord's statutory obligation to
mitigate its damages. Amounts received shall be applied against amounts due from
Tenant.

     14.5 In the event this Lease is terminated and whether or not the Leased
Premises be relet, Landlord shall be entitled to recover from the Tenant all
rent due and all reasonable expenses, including reasonable counsel fees,
incurred by Landlord in recovering possession of the Leased Premises, and all
reasonable costs and charges for the care of the Leased Premises while vacant,
which damages shall be due at such time as they are incurred by Landlord; and a
sum equal to all damages set forth in Paragraph 15. Without any previous notice
or demand, separate actions may be maintained by Landlord against Tenant from
time to time to recover any damages which have become due and payable to the
Landlord without waiting until the end of the term.

     150 LIABILITY OF TENANT FOR DEFICIENCY

     In the event that the relation of the Landlord and Tenant terminates by
reason of:

          (a) an uncured Event of Default by the Tenant and the re-entry of the
     Landlord as permitted herein; or

          (b) by the ejectment of the Tenant by summary proceedings or other
     judicial proceedings; it is hereby agreed that the Tenant shall remain
     liable to pay in monthly payments the rent and any other charges which
     shall accrue. The Tenant expressly agrees to pay as damages for such breach
     of this Lease the difference between the rent


                                       35
<PAGE>


     reserved and the rent received, if any, by the Landlord, during the
     remainder of the unexpired term.

     160 NOTICES

     All notices required by this Lease shall be given by certified mail, return
receipt requested, nationally recognized overnight courier or personal delivery
with receipt, at the address set forth on the first page of this lease, and/or
such other place as the parties may designate in writing. Any notices hand
delivered or sent by nationally recognized overnight carrier shall be deemed
delivered when received. All notices sent by mail shall be deemed given 3 days
after deposit in the mail. Upon Tenant's occupancy, Tenant's address for notices
shall be the Leased Premises.

     170 NON-WAIVER

     The failure of either party to insist upon the strict performance of any of
the terms of this Lease, or to exercise any option contained herein, shall not
be construed as a waiver of any such term. Acceptance of performance of anything
required by this Lease to be performed, with the knowledge of the breach of any
term of this Lease, shall not be deemed a waiver of such breach, nor shall
acceptance of rent by Landlord in a lesser amount than is due (regardless of any
endorsement on any check, or any statement in any letter accompanying any
payment of rent) be construed either as an accord and satisfaction or in any
manner other than as payment on account of the earliest rent then unpaid by
Tenant. No waiver of any term of this Lease shall be deemed to have been made
unless expressed in writing and signed by the benefitted party.

     180 RIGHT OF TENANT TO MAKE ALTERATIONS AND IMPROVEMENTS

     Upon occupancy the Tenant may make alterations, additions or improvements
to the Leased Premises provided the aggregate cost of same shall be less than
$50,000. If greater than $50,000 then Tenant must obtain the consent of the
Landlord, which shall not be unreasonably withheld or delayed. Tenant 


                                       36
<PAGE>


shall obtain all necessary governmental permits and shall furnish to Landlord
as-built drawings of any alterations, additions or improvements which are made.
Landlord agrees to review any alteration, addition, or improvements proposed by
Tenant within 10 days of receipt of plans and specifications, and advise Tenant
of its decision. If Landlord does not respond in 10 days, consent is deemed
given. Any approval given is not intended to subject the Landlord's property to
liability under any lien law.

     190 NON-LIABILITY OF LANDLORD

     Tenant agrees to assume all risk of damage to its property, equipment and
fixtures occurring in or with respect to the Leased Premises, whatever the cause
of such damage or casualty. Landlord shall not be liable for any damage or
injury to property or person caused by or resulting from steam, electricity,
gas, water, rain, ice or snow, or any leak or flow from or into any part of the
building, or from any damage or injury resulting or arising from any other cause
or happening whatsoever, unless arising from gross negligence or willful
misconduct of Landlord or its agents, contractors or employees.

     200 RESERVATION OF EASEMENT

     Landlord reserves the right, easement and privilege to enter on the Leased
Premises in order to install, at its own cost and expense, any storm drains and
sewers and/or utility lines in connection therewith as may be required by the
Landlord. It is understood and agreed that if such work as may be required by
Landlord requires an installation which may displace any paving, lawn, seeded
area or shrubs the Landlord, shall, at its own cost and expense, restore or
redesign said paving, lawn, seeded area or shrubs. The Landlord covenants that
the foregoing work shall not unreasonably interfere with the normal operation of
Tenant's business.

     210 STATEMENT OF ACCEPTANCE


                                       37
<PAGE>



     Upon the delivery of the Leased Premises to the Tenant the Tenant covenants
and agrees that it will furnish to Landlord a statement which shall set forth
the Date of Commencement and the Date of Expiration of the lease term.

     220 FORCE MAJEURE

     Except for (i) the obligation of the Tenant to pay rent and other charges,
(ii) the date by which Tenant may terminate this Lease because Landlord has not
substantially completed its work pursuant to Paragraphs 3 or 11 hereof, and
(iii) the time period set forth in Paragraph 7.4, the period of time during
which the Landlord or Tenant is prevented from performing any act required to be
performed under this Lease by reason of fire, catastrophe, industry wide
strikes, lockouts not instituted by Landlord, civil commotion, acts of God,
government prohibitions or preemptions or embargoes, inability to obtain
material or labor by reason of governmental regulations, the act or default of
the other party, or other events beyond the reasonable control of Landlord or
Tenant, as the case may be, shall be added to the time for performance of such
act.

     230 STATEMENTS BY LANDLORD AND TENANT

     Landlord and Tenant agree at any time and from time to time upon not less
than 10 days' prior notice from the other to execute, acknowledge and deliver to
the party requesting same, a statement in writing, certifying that this lease is
unmodified and in full force and effect (or if there have been modifications,
that the same is in full force and effect as modified and stating the
modifications), that it is not in default (or if claimed to be in default,
stating the amount and nature of the default) and specifying the dates to which
the basic rent and other charges have been paid in advance.

     240 CONDEMNATION

     24.1 If there is a condemnation or any similar proceedings and in Tenant's
reasonable opinion, said taking unreasonably or unduly interferes with the use
of the Leased Premises, the lease term created shall terminate from the date
when the authority exercising the power of eminent domain takes or 


                                       38
<PAGE>


interferes with the use of the Property. The Tenant shall be responsible for the
payment of rent until the time of surrender. In any event, no part of the
Landlord's condemnation award shall be claimed by the Tenant. Without
diminishing Landlord's award, the Tenant shall have the right to make a claim
against the condemning authority for such independent claim which it may have.

     24.2 In the event of any partial taking which would not be cause for
termination of the Lease, or in the event of any partial taking which would
permit termination but Tenant retains the balance of the Leased Premises
remaining after such taking, then the rent shall abate in an amount to be
mutually agreed upon (such agreement not to be unreasonably withheld or delayed)
between the Landlord and Tenant based on the extent of interference with
Tenant's normal use of the Leased Premises. The Landlord shall, to the extent
permitted by applicable law and as the same may be practicable promptly make
such repairs and alterations in order to restore the building and/or
improvements to usable condition to the extent of any condemnation award
received by Landlord.

     250 LANDLORD'S REMEDIES

     25.1 The rights and remedies given to the Landlord in this lease are
distinct, separate and cumulative remedies, and no one of them, whether or not
exercised by the Landlord, shall be deemed to be in exclusion of any of the
others.

     25.2 In addition to any other legal remedies for an Event of Default by the
Tenant or by anyone holding or claiming under the Tenant such Event of Default
shall be restrainable by injunction at the suit of the Landlord.

     25.3 No receipt of money by the Landlord from any receiver, trustee or
custodian or debtors in possession shall reinstate, continue or extend the term
of this lease or affect any notice theretofore given to the Tenant, or to any
such receiver, trustee, custodian or debtor in possession, or operate as a
waiver or estoppel of the right of the Landlord to recover possession of the
Leased Premises for any of the causes therein enumerated by any lawful remedy;
and the 


                                       39
<PAGE>


failure of the Landlord to enforce any covenant or condition by reason of its
breach by the Tenant shall not be deemed to void or affect the right of the
Landlord to enforce the same covenant or condition on the occasion of any
subsequent default or breach.

     260 QUIET ENJOYMENT

     The Landlord covenants that the Tenant, on paying the rental and performing
the covenants and conditions contained in this Lease, subject to applicable
notice and grace periods, may peaceably and quietly have, hold and enjoy the
Leased Premises for the Lease term.

     270 SURRENDER OF PREMISES

     On the last day, or earlier permitted termination of the Lease term, Tenant
shall quit and surrender the Leased Premises in good and orderly condition and
repair (reasonable wear and tear, and damage by fire or other casualty excepted)
and shall deliver and surrender the Leased Premises to the Landlord peaceably,
together with all alterations and improvements to the Leased Premises. Tenant
shall not be required to remove any alterations or improvements unless: (i)
Landlord advised Tenant in writing that Tenant would have to remove such items
when Landlord approved the alterations or received notice thereof from Tenant or
(ii) Landlord gives Tenant written notice on or before 6 months prior to the
expiration of the Term that the condition of such items is beyond normal wear
and tear and in such event Tenant shall be required to remove any alterations or
improvements installed by the Tenant, and restore the Leased Premises to its
original state, normal wear and tear and damage by fire or other casualty
excepted. Notwithstanding the above, Tenant shall not be required to remove any
alterations or improvements shown on Plans. Notwithstanding the above, Landlord
shall have a right, prior to the expiration of the Term, to notify Tenant that
Landlord shall purchase as many hoods and benches as it desires at a price of
$2300/hood and $50/lineal foot of bench. Said payment shall be made to Tenant in
a lump sum on the termination date. All 


                                       40
<PAGE>


property not removed by Tenant shall be deemed abandoned by Tenant, and Landlord
reserves the right to charge the reasonable cost of removal to the Tenant, for
items which Tenant was required to remove.

     280 HOLDOVER

     If the Leased Premises are not surrendered at the end of the Lease term,
the Tenant shall pay 150% of the Base Rent then being paid to Landlord, on a
monthly basis with rent pro-rated until date of surrender. These covenants shall
survive the termination of the Lease.

     obligations under this Lease;

          (b) Any negligence on the part of the Tenant or any of its agents,
     contractors, servants, employees, licensees or invitees;

          (c) Any accident, injury, damage to any person or property of third
     parties occurring in, or about the Leased Premises unless arising from
     negligence or willful misconduct of Landlord or any of its agents,
     contractors or employees, or the failure of Landlord to comply with its
     obligation under this Lease;


                                       41

     negligence or willful misconduct of Tenant or any of its agents,
     contractors or employees, or the failure of Tenant to comply with its
     obligation under this Lease.

     Tenant shall promptly notify Landlord of any such claim asserted against it
and shall promptly send to Landlord copies of all papers or legal process served

Jersey.



                                       42
<PAGE>


     310 BIND AND INURE CLAUSE

     The terms, covenants and conditions of this Lease shall be binding upon,
and inure to the benefit of, each of the parties hereto and their respective
heirs, successors and assigns.

     320 INCLUSIONS

     The neuter gender when used herein, shall include all persons and
corporations, and words used in the singular shall include words in the plural
where the text of the instrument so requires.

     330 DEFINITION OF TERM "LANDLORD"

     When the term "Landlord" is used in this Lease it shall be construed to
mean and include only the owner of title to the building. Upon the transfer by
the Landlord of the title, the Landlord shall advise the Tenant in writing by
certified mail, return receipt requested, of the name of the Landlord's
transferee. In such event, the Landlord shall be automatically freed and
relieved from and after the date of such transfer of title of all personal
liability with respect to the performance of any of the covenants and
obligations on the part of the Landlord herein contained to be performed,
provided any such transfer and conveyance by the Landlord is expressly subject
to the assumption by the transferee of all of the obligations of the Landlord
hereunder.

     340 COVENANTS OF FURTHER ASSURANCES

     If, in connection with obtaining financing for the improvements on the
Leased Premises, the mortgage lender shall request reasonable modifications in
this Lease as a condition to such financing, Tenant will not unreasonably
withhold, delay or refuse its consent thereto, provided that such modifications
do not in Tenant's reasonable judgment materially increase the obligations or
materially decrease the rights of Tenant hereunder or materially adversely


                                       43
<PAGE>


affect the leasehold interest hereby created or materially adversely affect
Tenant's use and enjoyment of the Leased Premises. Notwithstanding anything
contained in this paragraph, the rent shall not increase.

     350 COVENANT AGAINST LIENS

     Tenant agrees that it shall not encumber, or permit to be encumbered, the
Leased Premises or the fee thereof by any lien, charge or encumbrance, and
Tenant shall have no authority to mortgage or hypothecate this Lease in any way
whatsoever. Any violation of this Paragraph shall be considered a breach of this
Lease.

     360 SUBORDINATION

     This Lease shall be subject and subordinate at all times to the lien of any
mortgages or other encumbrances now or hereafter placed on the land and building
and Leased Premises without the necessity of any further instrument or act on
the part of Tenant to effectuate such subordination. However, Tenant agrees to
execute such further documents evidencing the subordination of the Lease to the
lien of any mortgage or ground lease as shall be reasonably requested by
Landlord. It is a condition precedent to Tenant's obligation to pay rent
hereunder and the foregoing subordination, that Landlord shall provide Tenant
with a non-disturbance agreement from any current or future mortgagee, which
shall provide that so long as no Event of Default has occurred and is
continuing, Tenant's rights under this lease shall not be disturbed. Landlord
shall provide Tenant with the non-disturbance agreement from any such current or
future mortgagee within the later of loan closing or 60 days of Lease execution.
Notwithstanding any language to the contrary contained herein, this Lease shall
not be subordinated until Tenant receives a copy of the non-disturbance
agreement.

     370 EXCULPATION OF LANDLORD

     Neither Landlord nor its principals shall have any personal obligation for
payment of any indebtedness or for the performance of any


                                       44
<PAGE>


obligation under this Lease. The performance of Landlord's obligations expressed
herein may be enforced only against the land and building, and the rents, issues
and profits thereof and insurance and condemnation proceeds. The Tenant agrees
that no deficiency judgment or other judgment for money damages shall be entered
by it against the Landlord or its principals personally in any action. This
exculpation provision shall not apply to misappropriation of Tenant's security
deposit or the aforesaid letter of credit.

     380 SECURITY

     The Tenant shall deposit with the Landlord 1 month's security, calculated
in accordance with Paragraph 4.1, as security for the full and faithful
performance of its obligations under this Lease. Payment shall be made 1/3 each
month for the first 3 months of the Lease Term. Upon termination of this Lease,
and providing that at such time no Event of Default has occurred and is
continuing, the Landlord shall return the security deposit to the Tenant within
30 days of the date of termination. Tenant covenants and agrees that it will not
assign, pledge, hypothecate, mortgage or otherwise encumber the security during
the term of this Lease. It is expressly understood and agreed that the Landlord
shall not be required to segregate the security.

     390 BROKERAGE

     The parties mutually represent to each other that Tom Giannone of Julien J.
Studley, Inc. is the broker who negotiated and consummated the within
transaction, and that neither party dealt with any other broker in connection
with the Lease. It is agreed that the Landlord shall be responsible, at its sole
cost and expense, to pay the brokerage commission in connection with this Lease.

     400 LATE CHARGES

     In addition to any other remedy, a late charge of 1% per month shall be due
and payable, without notice from Landlord, on any portion of rent or other
charges not paid within 10 days of when it is due.

     41.1 Provided there is no continuing Event of Default, Tenant has the right
to renew the lease, for two 5 year periods, to commence at the end of the
initial term of this Lease. The renewal shall be upon the same terms and
conditions as contained in this Lease, except as follows:

          (a) For the first 5 year renewal period, the annual rent per square
     foot shall be the lesser of $28.00 or the average of the rent then paid by
     2 of Landlord's existing tenants, Biomira USA, Inc. at 1002 Eastpark Blvd.,
     Cranbury, NJ, and Pharmacopeia, Inc., at 3000 Eastpark Blvd., Cranbury, NJ
     or their successors or assigns. In the event either of those tenants, its
     successor or assigns have vacated the premises, then the rent for the
     laboratory/office space shall be the lesser of $28.00 or $25.50 times 1
     plus the percentage increase in the Consumer Price Index ("CPI") over the
     initial 10 years of the lease term; and the rent for the executive office
     space shall be the lesser of $18.43 or $16.75 times 1 plus the percentage
     increase in the CPI during the same term. The CPI to be used shall be the
     "All Items" index figures for the N.Y. Northeastern N.J. average of the CPI
     for All Urban Consumers (revised CPI-U) (1982-1984 = 100) published by the
     U.S. Department of Labor. The rent for all expansion Phases during both
     renewal terms shall be as set forth in Paragraph 4.2.

          (b) For the second 5 year renewal period, the rent per square foot
     shall be the rent during the first 5 year renewal period increased by 10%.

     41.2 Since the rent payment for at least the first month of the renewal
term will have been paid prior to the determination of any applicable rent
increase in excess of the Original Base Rent, any increase for months already
elapsed after commencement of the renewal term shall be added to the next
monthly rent payment then becoming due and payable.

     41.3 The options of the Tenant to renew this Lease are expressly
conditioned upon the Tenant delivering to the Landlord a notice, in writing, by
certified mail, return receipt requested at least 9 months prior to the date
fixed for 


                                       46
<PAGE>


termination of the original Lease term or any renewal term, provided Landlord
will allow Tenant to exercise the option in less than 9 months if Landlord has
not first given a notice to Tenant of the pendency of the option.

     41.4 In the event that the Index figure is discontinued the parties shall
agree on an equivalent and substituted Cost of Living Index to be applied in the
same manner. In the event the parties cannot mutually agree as to a substituted
Index, then the issue shall be submitted for arbitration to the American
Arbitration Association to take place in New Brunswick or any of its contiguous
municipalities, with the cost thereof divided between the parties. If the base
year (1982-84 equal to 100) hereinabove referred to with respect to the "Index"
shall be changed after the execution of the Lease, appropriate adjustments based
on such new Index shall be made so as to have a proper application of the Cost
of Living formula.

     420 RIGHT TO LEASE ADDITIONAL SPACE

     42.1 Landlord shall not attempt to rent any other space at 8 Cedar Brook
Drive until commencement of the erection of the structural steel. Thereafter,
Landlord shall be free to lease space in any area where Tenant is not paying a
Reservation Fee, subject to a right of first refusal by Tenant as provided in
Paragraph 42.3. Provided Tenant has not given the notice under Paragraph 4.2(i),
Landlord shall agree to lease portions of Phase 3 from north to south.

     42.2 If Tenant has leased all of Phase 2 or is paying the Reservation Fee
thereon, Tenant shall have, for a 2 year period from the Commencement Date, the
right of first refusal pursuant to Paragraph 42.3 for all, or the portion of
Phase 3 not then reserved, at the rental rates set forth in paragraph 4.2.
However, if Tenant has not leased all of Phase 2 and provides Landlord with the
notice required under Paragraph 4.2(i) that it is cancelling its option to lease
such space or the 2 year period has expired, and as a result Tenant ceases to
pay the Reservation Fee for Phase 2, the right of first refusal with regard to
Phase 3 shall 


                                       47
<PAGE>


immediately terminate and it shall have the right of first offer set forth in
Paragraph 42.4.

     42.3 If Landlord negotiates any lease for Phases 2 or 3 or any portion
thereof while such space is still subject to Tenant's right of first refusal, it
shall give Tenant written notice of same. Tenant shall then have 21 calendar
days to notify Landlord that it will lease the space in which the third party is
interested, at the rent set forth in Paragraph 4.2. If Tenant declines to
exercise its right of first refusal to rent such space, it shall still have the
option of reserving that space, by paying Landlord $8/sq. ft., inclusive of
common area maintenance and real estate taxes. Such reserved space may only be
cancelled upon Tenant giving to Landlord 6 months notice. The provisions for the
termination of the Reservation Fee shall also apply to the $8/sq. ft. amount set
forth in this subparagraph and in Subparagraph 42.4.

     42.4 If all of Tenant's rights of first refusal have expired, Landlord
agrees that Tenant shall still have the right to meet any serious offers to
lease space in the building that Landlord makes to other tenants. It is the
intent of this Lease that each party will cooperate with the other and keep the
other party reasonably advised of its plans with regard to expansion and
leasing. In that regard to the extent that Landlord is entertaining a serious
offer from a third party to lease any space in the building, it will notify
Tenant of same and Tenant shall sign a confidentiality agreement with regard to
the details of said lease negotiations. Tenant shall then have a period of 14
calendar days to notify Landlord that it will either meet the third party offer
for the space; reserve the space at $8.00/sq. ft., inclusive of common area
maintenance and real estate taxes; or reject the offer and allow Landlord to
lease said space to the third party on substantially the same terms contained in
the original offer. If Tenant reserves said space, it may only cancel upon
Tenant giving Landlord 6 months notice. However, if Tenant does cancel, then
Landlord shall be free to market 


                                       48
<PAGE>


that particular space without any further right to offer the space to Tenant in
the future.

     42.5 In the event Tenant declines to lease or reserve any expansion Phases,
Landlord will make reasonable efforts, without any guarantee of results, to
include a clause in any third party tenant's lease that requires that tenant to
relocate if Tenant decides to lease the space. If, after Tenant gives notice
that it intends to lease the space occupied by the third party tenant, the
Landlord is only able to relocate said tenant to new space at a lower than
market rent, then Tenant shall either (1) revoke its notice of intention to
lease the third party tenant's space; or (2) pay, on a quarterly basis, the
differential between the rent the tenant was paying and the lower than market
rent the tenant will pay in the space to which it is relocated.

     43. MEMORANDUM OF LEASE

     The parties shall forthwith execute a short form memorandum of this Lease
Agreement in recordable form to be recorded upon Landlord's receipt of the first
month's rent.

             FOR VALUE RECEIVED, and as an inducement to CEDAR BROOK
CORPORATE CENTER, L.P. ("Landlord"), to enter into a certain lease with
TRANSCELL TECHNOLOGIES, INC. ("Tenant"), dated September 19, 1996, demising a
portion of the premises known as 8 Cedar Brook Drive, Cranbury, New Jersey 08512
("Lease"), to which this Guaranty is attached, Interneuron Pharmaceuticals,
Inc., One Ledgemont Center, Suite 340, 99 Hayden Ave., Lexington, MA 02173
("Guarantor"), hereby guarantees to Landlord, its successors and assigns, the
full performance and observance of all of the covenants, conditions, obligations
and agreements in the Lease to be performed and observed by Tenant, its
successor and assigns, from the signing of the Lease and for a period of 5 years
after the Commencement Date, including the balloon payment referred to in
paragraph 3.1(b) of the Lease, and expressly agrees that the validity of this
agreement and the obligations of Guarantor hereunder shall be and the same are
direct and primary and shall not be terminated, affected or impaired by reason
of the assertion by Landlord against Tenant, its successors or assigns, of any
of the rights or remedies reserved to Landlord pursuant to the provisions of the
Lease or by reason of the waiver by Landlord of, or the failure of Landlord to
enforce, any of the terms, covenants, conditions or obligations of Tenant under
the Lease, or the granting of any indulgence or extension of time to Tenant, its
successors or assigns, all of which may be given or done without notice to
Guarantor. Notwithstanding any language to the contrary contained herein, this
Guaranty shall not cover, and Interneuron shall not be liable, for the payment
of any sums set forth in the Lease which are secured by a letter of credit
(including without limitations the sums specified in Paragraph 3.1(a) of the
Lease).
 
     Landlord shall provide Guarantor with prompt notice of default in the
payment of rent, additional rent or any other amounts contained or reserved in
said Lease, and notice of a breach of nonperformance of any of the covenants,
conditions or agreements contained in the Lease and the opportunity to promptly
cure any such default or breach.

     Guarantor further covenants and agrees that this agreement and guaranty
shall remain and continue in full force and effect as to any amendment,
modification, renewal or extension of the Lease, to all of which Guarantor
hereby consents in advance, provided however and only to the extent same do not
increase the term of the lease, the amount of space leased or the rent, and no
course of 


<PAGE>


dealing between Landlord, its successors and assigns, and Tenant, its successors
and assigns, shall diminish, impair in any respect or abrogate the obligation of
Guarantor hereunder except as hereinabove set forth.

     Guarantor further agrees that its liability hereunder shall be primary and
that, in any right of action which shall accrue to Landlord, its successor and
assigns, may, at its or their option, proceed against Guarantor without having
commenced any action, or having obtained any judgment, against Tenant.

     Guarantor further represents to Landlord, as an inducement for it to make
the Lease, that Guarantor has a financial interest in Tenant; and that the
execution and delivery of this guaranty are not in contravention of its charter
or by-laws, and have been duly authorized by its Board of Directors, and
Guarantor will comply with all requirements of New Jersey law to make the
Guaranty valid, subsisting and enforceable in accordance with New Jersey law.

     Guarantor acknowledges that Tenant, its successors and assigns, may assign
the Lease pursuant to Paragraph 10 thereof, and Guarantor hereby agrees that no
assignment(s) or transfer(s) of the Lease by Tenant or any succeeding Tenant(s)
shall operate to extinguish or diminish the liability of the Guarantor under
this Guaranty, and that Guarantor shall, nevertheless, remain fully liable under
this Guaranty during the 5 year term of this Guaranty, unless Landlord following
any such assignment, shall determine in its sole and absolute judgment that the
financial responsibility of such assignee and/or any guarantor of the
obligations of such assignee under the Lease are satisfactory to Landlord, and
Landlord, in its sole and absolute discretion, shall elect to release the
Guarantor from its obligations hereunder. Notwithstanding the above, Landlord
agrees that in the event Guarantor (a) sells the Tenant; or (b) the Tenant
assigns the Lease pursuant to Paragraph 10 of the Lease; or (c) Tenant becomes a
publicly owned company; and the purchasing company, the assignee or the public
company, as the case may be, has an amount of cash equal to or greater than the
amount of cash possessed by Guarantor at the time the Lease is signed, then this
Guaranty shall automatically expire. If the purchasing company, the assignee or
the public company has less cash than Guarantor at the time the Lease is signed,
but has at lease fifty million dollars in cash, then Landlord shall release
Guarantor from this Guaranty if such entity either (1) provides Landlord with an
unconditional Letter of Credit, or another form of collateral which is
reasonably satisfactory to both Landlord and the 


                                      -53-
<PAGE>


lender that financed the Tenant Improvements, for all rent to come due for the
balance of the 5 year guarantee period and the balloon payment set forth in
Paragraph 3.1(b) of the Lease; or (2) agrees to add to the rent due Landlord in
Paragraph 4 of the Lease an additional $3.00/sq. ft. from the date of the sale,
assignment or public issue, as the case may be, to the end of the 6th full year
of the Lease term. In the event the purchasing company, the assignee or the
public company elects option (2), and maintains cash of at least fifty million
dollars for 4 consecutive quarters after said election, then the $3.00/sq. ft.
additional rent shall decrease to $1.50/sq. ft. at the start of the 5th quarter
and continue at that level until the end of the 6th full year of the Lease term.

     Guarantor agrees that if during the 5 year term of this Guaranty the Tenant
shall become insolvent or shall be adjudged a bankrupt, or shall file a petition
for reorganization, arrangement or similar relief under any present or future
provision of the United States Bankruptcy Code or the bankruptcy or receivership
laws of the United States or the State of New Jersey or if such a petition filed
by creditors of Tenant shall be approved by a Court, or if Tenant shall seek a
judicial readjustment of the rights of its creditors under any present or future
Federal or State law or if a receiver of all of its property and assets is
appointed by any State or Federal Court, and in any such proceeding the Lease
shall be terminated or rejected, or the obligations of Tenant thereunder shall
be modified, Guarantor agrees that it will immediately pay to Landlord or its
successors or assigns an amount equal to all fixed, contingent and additional
rent accrued (and unpaid) to the date of such termination, rejection or
modification, and when due, the rent and additional rent which would have been
payable under the Lease during the unexpired portion of the term occurring prior
to the fifth anniversary of the Commencement Date, less the aggregate of rentals
received by Landlord, its successors and assigns, either from Tenant, or tenants
occupying the demised premises or any portion thereon during such unexpired
portion of the term occurring prior to the fifth anniversary of the Commencement
Date. Any lump sum payment made by Guarantor pursuant to this Paragraph shall be
discounted assuming an interest rate of 4%.

     Guarantor's obligation to make payment in accordance with the terms of this
Guaranty shall not be impaired, modified, changed, released or limited in any
manner whatsoever by any impairment, modification, change, release or limitation
of the liability of Tenant or its estate in bankruptcy resulting from the
operation of any present or future provision of the Federal bankruptcy 


                                      -54-
<PAGE>


statute or other statute, or from the decision of any court. By execution of the
within Guaranty, the Guarantor does hereby covenant, agree and acknowledge that
it irrevocably submits to the jurisdiction of the State of New Jersey and agrees
that the within Guaranty shall be construed in accordance with the laws of the
State of New Jersey in connection with its obligations as Guarantor as in this
Guaranty provided.

     This Guaranty is for the benefit of the Landlord and any present or future
bona fide first mortgagee, their successors and assigns, as additional
collateral for any present or future mortgage loan to the Landlord.

     This Guaranty shall be null and void and of no further force or effect
after the fifth anniversary of the Commencement Date.

     IN WITNESS WHEREOF, the parties hereto have hereunto set their hands and
seals, or caused these presents to be signed by their proper corporate officers
and caused their proper corporate seals to be hereto affixed, the day and year
first above written.

     WHEREAS, the parties wish to amend the Lease;

     NOW, THEREFORE, the parties hereto covenant and agree as follows:

     1. Pursuant to Paragraph 1.2 of the Lease, Tenant has an option to expand
the Leased Premises by renting an adjacent area referred to as Phase 2B and
consisting of 10,682 square feet. The parties have agreed that the Landlord
shall have the right to use approximately 5,444 square feet of Phase 2B as shown
on Schedule A attached hereto for temporary office space ("Temporary Office
Space") until approximately January 1, 1999.

     2. During the time that the Landlord is utilizing the Temporary Office
Space, Tenant shall not be responsible for paying any Reservation Fee or utility
cost for said area (approximately 5,444 square feet). Utilities for said space

     3. At the conclusion of the Tenant's use of the Temporary Office Space,
Intercardia shall have the following three (3) options to choose from:

          ii. Intercardia can take over the occupancy of the Temporary Office
     Space in "as is" condition and pay $12.50 per square foot (net) for the
     approximately 5,444 square feet and continue to pay the $5.00 per square
     foot Reservation Fee for the remainder of the original reserved area.

          iii. Landlord agrees to return the Temporary Office Space to the 


                                       56

     their rights under the Lease Agreement to commence use of the Reserved

     4. Except as hereinabove referred to, all other terms and conditions of the
Lease shall remain in full force and effect, unimpaired and unmodified.
 
     5. This Agreement shall be binding upon the parties hereto, their heirs,
successors, and assigns.

however, National Jewish shall make no such disclosure unless National Jewish
shall have provided the Sponsor with a copy of any proposed publication

author to a third party of any written materials intended for publication. If
the proposed disclosure contains Sponsor's Confidential Information, National
Jewish shall remove or cause the author to remove such Sponsor Confidential
Information prior to submission for publication or other public disclosure. The
Sponsor may request, and National Jewish shall agree to, a delay of such
proposed publication for an additional period, not to exceed forty-five (45)
days, in order to protect the potential patentability of any invention described
therein by having National Jewish or Sponsor prepare and file a patent
application. All publications resulting from this Agreement will include an

     All confidential information of either party disclosed to the other party
in connection with the Research hereunder ("Confidential Information") will be
treated by the receiving party as confidential and restricted in its use to only
those uses contemplated by the terms of this Agreement. Any information which is
to be treated as confidential must be clearly marked as confidential prior to
transmittal to the other party. If such Confidential Information is disclosed
orally, it shall be identified as being confidential at the time of disclosure,
and shall thereafter be reduced to writing within 30 days, marked as
confidential, and transmitted to the receiving party. The Sponsor may submit
Confidential Information only to the Principal Investigator or Crapo, who shall
be free to refuse to accept such Confidential Information. The obligations of
this paragraph shall survive and continue for five (5) years after termination
of this Agreement. Specifically excluded from such confidential treatment shall
be information which: (a) is or becomes part of the public domain, through no
fault of the receiving party; (b) is lawfully disclosed to the receiving party
by a third party who is not obligated to retain such information in confidence;
(c) is independently developed at the receiving party by someone not privy to
the confidential information; (d) is required to be disclosed to comply with
applicable laws or governmental regulations, provided that the disclosing party
receives prior notice of such disclosure and that the receiving party takes all

     Each party shall retain full ownership of all its Confidential Information
in the possession of the other party. At the termination of this Agreement, each
party shall secure the return of, or destroy, any Confidential Information that
is in its possession and that is owned by the other party.

Paragraph 8(a) of the Agreement is replaced in its entirety by the following.

8.   Results of the Research

     (a) All rights in any inventions or discoveries, whether or not patentable,
that are developed, conceived or reduced to practice in the course of the
Research or within the field of antioxidant compounds, nitrosylating compounds
or related discoveries from the research laboratories of Crapo, Day or Chang
solely by any persons, including Crapo, Day or Chang who work in their
respective laboratories under their supervision and are students, lab employees
or post-doctoral fellows ("National Jewish Employees") shall be property of
National Jewish ("National Jewish Inventions"). All rights in any inventions or
discoveries whether or not patentable, that are developed, conceived or reduced
to practice jointly by National Jewish Employees and Sponsor employees or
consultants in the course of the Research or within the field of antioxidant
compounds, nitrosylating compounds or related discoveries from the research
laboratories of Crapo, Day or Chang shall be jointly owned by National Jewish
and the Sponsor ("Joint Inventions"). Title to any Joint Inventions,
developments or discoveries resulting directly from the Research will be
determined in accordance with U.S. Patent law, Title 35 U.S.C., in effect at the
time of the invention, development or discovery. All rights in any inventions or
discoveries whether or not patentable, that are developed, conceived or reduced
to practice in the course of the Research solely by Sponsor employees or
consultants and without the use of any National Jewish resources or facilities
shall be property of the Sponsor. National Jewish shall promptly report to the
Sponsor any National Jewish Inventions. Both parties agree promptly to inform
the other party of any Joint Inventions. All license negotiation periods for any
type of invention hereunder shall be limited to between 90 and 120 days after
the option to license is exercised. For the purpose of this Section 8 only, any
National Jewish Employees may not be defined as a Sponsor consultant or
employee.

Paragraph 8(b) of the Agreement is replaced in its entirety by the following.

8.   Results of the Research

     (b) National Jewish grants to Sponsor an option to negotiate for a
royalty-bearing exclusive license to any patent application filed by National
Jewish on any National Jewish Invention or Joint Invention resulting from the
Research or within the field of antioxidant compounds, nitrosylating compounds
or related discoveries from the research laboratories of Crapo, Day or Chang by
National Jewish Employees and any patents granted thereon, for an initial option
period of ninety (90) days after a patent has been filed on such invention.
Sponsor may elect to extend such option for a period not to exceed one hundred
twenty (120) days, provided the Sponsor reimburses National Jewish for all costs
related to the filing, prosecution and maintenance of said patent(s) or patent
applications. National Jewish and Sponsor agree that the royalty rate and other
license terms to be negotiated in any such license agreement(s) shall be fair,
reasonable, and customary for the industry to which the invention applies. In
addition, the royalty shall reflect the relative contributions of National
Jewish and of Sponsor in making the invention. It is anticipated by the parties
that a reasonable royalty rate on small molecule antioxidant compounds will be
approximately one percent to two percent of ultimate net sales of any product
developed. Royalties on inventions not contemplated in the scope of this
Agreement may result in royalty rates higher than those payable in connection
with the license of small molecule antioxidant compounds. In the event that
National Jewish and Sponsor are not able to reach agreement regarding the terms
of a license agreement for a National Jewish or Joint Invention, National Jewish
shall be free to offer a license (which would be a non-exclusive license in the
case of a Joint Invention) on terms it deems appropriate to third parties;
provided, however, National Jewish shall not offer a license to any such third
party on terms more favorable than those offered to Sponsor without first
offering Sponsor an opportunity to accept a license on the same terms as
National Jewish proposes to offer to such third party.
