              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                            JUNE 30, 1996 (UNAUDITED)

1.  BASIS OF PRESENTATION

    The accompanying  unaudited and condensed financial information of EntreMed,
    Inc. ( the "Company")  includes the accounts of its wholly owned subsidiary,
    Cytokine Sciences,  Inc. The Company formed Cytokine Sciences,  Inc. in June
    1996 for the purpose of  acquiring  the assets of  Innovative  Therapeutics,
    Inc. See Note 5 - Subsequent Events.

    The accompanying unaudited condensed consolidated financial statements
    have been prepared in accordance with generally accepted accounting
    principles for interim financial information and in accordance with the
    instructions to Form 10-Q and Article 10 of Regulation S-X.
    Accordingly, such financial statements do not include all of the
    information and disclosures required by generally accepted accounting
    principles for complete financial statements. In the opinion of
    management, all adjustments (consisting of normal recurring accruals)
    considered necessary for a fair presentation have been included.
    Operating results for the three- and six-month periods ended June 30,
    1996 are not necessarily indicative of the results that may be expected
    for the year ending December 31, 1996. For further information, refer
    to the Company's audited financial statements and footnotes thereto
    included in the Company's Prospectus dated June 11, 1996.

2.  NET LOSS PER SHARE

    Pro Forma Net Loss Per Share

    Net loss per common share and weighted average shares outstanding for
    the periods presented give effect to the automatic conversion of
    3,000,000 shares of preferred stock into 2,000,000 shares of common
    stock as of the date of the Company's initial public offering on June
    11, 1996. Pursuant to Securities and Exchange Commission Staff
    Accounting Bulletin Number 83, common and convertible preferred stock
    issued for consideration below the initial public offering price of
    $15.00 and stock options and warrants issued with exercise prices below
    the initial public offering price during the twelve-month period
    preceding the initial filing of the registration statement, have been
    included in the calculation of common shares, using the treasury stock
    method, as if they were outstanding for all periods prior to the
    effective date of the initial public offering. Net loss per common
    share is computed based on the weighted average number of common shares
    and, when dilutive, common equivalent shares (stock options and
    warrants) outstanding during each of the periods.

3.  INITIAL PUBLIC OFFERING

    On June 17, 1996, the Company completed an initial public offering of
    3,200,000 shares of the Company's common stock at a price of $15.00 per
    share. Bristol-Myers Squibb Company, a party to a collaboration with
    the Company, also purchased from the Company in a private placement on
    the closing of the offering 333,333 shares of the Company's common
    stock at $15.00 per share. The initial public offering resulted in net
    proceeds to the Company of approximately $43,500,000 and the private
    placement with Bristol-Myers Squibb Company ("BMS") resulted in net
    proceeds to the Company of an additional $5,000,000.

4.  CONTINGENCIES

    The Company is a party to certain litigation filed in August 1995 in
    the United States District Court for the Eastern District of Tennessee
    by Bolling McCool & Twist, a consulting firm. The suit relates to a
    claim for services rendered in the approximate amount of $50,000 and
    seeks a finder's fee in an unspecified amount in connection with the
    Bristol-Myers collaboration. Due to the early stage of the proceedings,
    the Company is unable to predict with certainty the eventual outcome of
    the lawsuit. The Company is contesting the action vigorously and
    believe that this proceeding will not have a material adverse effect on
    the Company or its financial statements, although there can no
    assurance that this will be the case.

5.  SUBSEQUENT EVENT

    In July 1996, the Company's previously wholly-owned subsidiary acquired
    substantially all of the assets of Innovative Therapeutics, Inc. in
    exchange for 15% of the common stock of Cytokine Sciences and research
    funding commitments. Innovative Therapeutics, Inc. previously performed
    early-stage research on methods for treating infectious diseases by
    stimulating cellular immunity. Most of the research activities of
    Innovative Therapeutics prior to the acquisition had been funded under
    a collaboration agreement between Innovative Therapeutics and the
    Company.

ITEM 2.    MANAGEMENT'S DISCUSSIONS AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS.

GENERAL
           Since its inception in September 1991, the Company has devoted
substantially all of its efforts and resources to sponsoring and conducting
research and development on its own behalf and through collaborations with
corporate partners and academic research and clinical institutions, and
establishing its facilities and hiring personnel. In December 1995, the Company
entered into a collaboration agreement with Bristol-Myers Squibb ("BMS") in
which BMS made an equity investment in the Company and agreed to pay certain
research and development fees and expenses, license fees, milestone payments,
and royalties on net sales, if any. Through June 30, 1996, with the exception of
license fees and research and development funding from BMS and certain research
grants, the Company had not generated any revenue from operations. The Company
anticipates its revenue sources for the next several years will be limited to
research grants and future collaboration payments from BMS and from other
collaborators under arrangements that may be entered into in the future. The
timing and amounts of such revenues, if any, will likely fluctuate and depend
upon the achievement of specified milestones.

RESULTS OF OPERATIONS

Three Months Ended June 30, 1996 and 1995

           Revenues increased to $1,092,500 during the three months ended June
30, 1996 ("1996 Three Months") from approximately $88,000 during the three
months ended June 30, 1995 ("1995 Three Months"). This increase primarily
reflects revenue received under the BMS collaboration agreement, which was
executed in December 1995. The collaborative research and development fees
relate to the amortization over five years of a one-time payment of $2,500,000
received in December 1995 and the amortization of semi-annual payments of
$1,835,000 under the BMS collaboration agreement. The license fee represents the
amortization over five years of a one-time $1,000,000 license fee received in
December 1995 under the BMS collaboration agreement.

           Research and development expenses increased by 12% from approximately
$1,116,000 in the 1995 Three Months to $1,246,000 in the 1996 Three Months.
Research and development expenditures include sponsored research payments to
academic collaborators and costs related to the Company's internal research
programs. The increase in research and development costs reflects increased
efforts in the Company's sponsored research and product development programs
related to its angiogenesis and cell permeation technologies, offset in part by
a reduction in expenditures relating to the development of vaccines.

           General and administrative expenses remained relatively constant at
approximately $472,000 during the 1996 Three Months, as compared to
approximately $467,000 in the 1995 Three Months. The Company anticipates that
general and administrative expenses will increase in the future to support
increased management and administrative expenses related to research and
development activities and as a result of additional costs associated with being
a publicly-held company.

           Interest income increased to $169,000 for the 1996 Three Months from
$6,000 for the 1995 Three Months. This increase is a result of the investment of
the proceeds received from the BMS collaboration agreement in December 1995 and
June 1996 and the capital raised in the Company's initial public offering.

Six Months Ended June 30, 1996 and 1995

           Revenues increased to $2,185,000 during the six months ended June 30,
1996 ("1996 Six Months") from approximately $88,000 during the six months ended
June 30, 1995 ("1995 Six Months"). This increase primarily reflects revenue
received under the BMS collaboration agreement, which was executed in December
1995. The collaborative research and development fees relate to the amortization
over five years of a one-time payment of $2,500,000 and the amortization of
semi-annual payments of $1,835,000 under the BMS collaboration agreement. The
license fee represents the amortization over five years of a one-time $1,000,000
license fee under the BMS collaboration agreement.

           Research and development expenses increased by 22% from approximately
$2,713,000 in the 1995 Six Months to $3,309,000 in the 1996 Six Months. This
increase reflects increased efforts in the Company's sponsored research and
product development programs related to its angiogenesis and cell permeation
technologies, offset in part by a substantial reduction in expenditures relating
to the development of vaccines.

           General administrative expenses increased by 35% in the 1996 Six
Months to approximately $1,244,000 from $922,000 in the 1995 Six Months. This
increase in general and administrative expenses primarily reflects a one time
charge of $233,000 related to future payments to a founder and former director
of the Company as compared to $45,000 of consulting fees to this individual
during the 1995 Six Months. The Company anticipates that general and
administrative expenses will increase in the future to support increased
research and development activities and as a result of additional costs
associated with being a publicly-held company.

           Interest income increased to $246,000 in the 1996 Six Months from
$11,000 in the 1995 Six Months. This increase is a result of the investment of
additional working capital generated from the BMS collaboration agreement and
the capital raised in the Company's initial public offering.

Liquidity and Capital Resources

           At June 30, 1996, the Company had cash and cash equivalents of
approximately $55,500,000 and working capital of approximately $51,600,000,
primarily representing the net proceeds of the Company's initial public offering
and private placement with BMS in June 1996 together with funds received under
the BMS agreement entered into in December 1995. Prior to December 1995, the
Company funded its operations from proceeds of private placements of equity
securities which raised approximately $17,000,000, various grants totaling
approximately $437,000, and certain borrowings.

           The Company's cash resources have been used to finance research and
development, including sponsored research, capital expenditures, including
leasehold improvements to the Company's laboratory facility, and general and
administrative expenses. Over the next several years, the Company expects to
incur substantial additional research and development costs, including costs
related to early-stage research in areas not reimbursed by BMS, preclinical and
clinical trials, increased administrative expenses to support its research and
development operations and increased capital expenditures for pilot
manufacturing capacity, various equipment needs and facility improvements.

           As of August 1, 1996, the Company was a party to sponsored research
agreements and clinical trials requiring the Company to fund an aggregate of
approximately $10,669,000 through 1999 ( including $6,000,000 to Children's

hereby.

         4.05 CONSENTS AND APPROVALS. No authorization, consent, approval or
other order of, or declaration to or filing with, any governmental agency or

         4.09 TITLE TO ASSETS; LEASES. (a) The Corporation has good and
marketable title to all the Assets free and clear of all Liens. The Assets
constitute all of the assets which are being used in the Business and all that
are required to operate the Business as presently operated. The Fixed Assets are
in good and serviceable condition and are suitable for the uses intended, and
their use conforms to applicable law and regulations. All of the Assets will on

the Business.

                  (b) The Corporation does not own any real property and is not
a party to or bound by any contract or agreement for the purchase or sale of any
real property. All real property and buildings and Assets held under leases by
the Corporation and used in the conduct of the Business are held under valid,
subsisting and enforceable leases (copies of which are set forth in Schedule
4.09 hereto). With respect to each of such leases: (i) the Corporation has not
received any notice or communications from the landlord (or lessor) advising or
claiming that the Corporation is in default under said leases or that the
Corporation has failed to perform or observe any term, agreement or obligation
on the part of the Corporation to be performed thereunder; (ii) there exists no
event which, with the giving of notice or lapse of time or both, would become a
default under any of said leases on the part of the Corporation; (iii) all sums
required to be paid by the Corporation to the landlord (or lessor) or any other

knowledge of the Corporation, the landlord (or lessor) has performed and

the Corporation has not received any notice of violation of the foregoing.

1.01(b) hereto is a list of all United States and foreign patents, trademarks,
trade names, copyrights, and applications therefor, used by the Corporation in
the conduct of the Business (the "Intellectual Property") and a description in
reasonable detail of all trade secrets or know how used by the Corporation in
the conduct of the Business (the "Trade Secrets"). The Corporation owns or
possesses adequate and valid licenses or other rights to use all Intellectual
Property; and the conduct of the Business as now being conducted by the
Corporation and as contemplated to be conducted in the future does not conflict
with any valid patents, trademarks, trade names or copyrights of others except
as may be permitted under valid license agreements to which the Corporation is a
party and which are set forth in Exhibit 1.01 (b) hereto. There are no claims,
demands or proceedings pending or, to the knowledge of the Corporation,
threatened by any third party pertaining to or challenging the validity of or
the Corporation's right to use any of the Intellectual Property or Trade
Secrets. The Corporation knows of no infringement by any party of its rights
with respect to any of the Intellectual Property and the Corporation knows of no
facts which would render any of the Intellectual Property invalid or
unenforceable.

         4.11 CONTRACTS; COMMITMENTS. Except as set forth in Schedule 4.11
hereto,  the  Corporation  is not a party to any  lease,  agreement,  indenture,
mortgage, loan agreement, note, guaranty,  agreement granting a Lien or negative

                                      -19-

<PAGE>

Corporation, commitment, employment agreement, pension plan, profit sharing
plan, collective bargaining agreement, employee benefit plan, other agreement
with respect to employment or compensation, joint venture agreement, agreement
with sales representatives or distributors, agreement for the purchase or sale
of supplies, materials, services or finished product, or other contract (each
such matter set forth on Schedule 4.11 being referred to as a "Material
Contract"). The Corporation is not in default under any Material Contract, and
to the knowledge of the Corporation, no other party or parties are in default
under any Material Contract. Between the date hereof and the Closing Date, the
Corporation will not enter into any contract or commitment except in the usual
and ordinary course of business and consistent with its business practices
heretofore followed. The Corporation is not renegotiating or making any payments
in lieu of performing any such contracts or commitments. The Corporation is not
subject to any purchase commitment in excess of its normal business requirements
or requiring the payment of prices in excess of market prices in effect at the
time such commitment was made.

         4.12 NO MATERIAL ADVERSE CHANGE. Since December 31, 1995, there has not
occurred any material adverse change in the condition (financial or otherwise),
assets, properties or business of the Corporation. Since such date the

or unmatured or otherwise, not sold any material assets and not entered into any
contracts or agreements except as set forth in Schedule 4.12 hereto; (b)

<PAGE>

         4.13 LITIGATION INVOLVING THE BUSINESS. Except as set forth in Schedule
4.13 hereto, the Corporation is not a party to, and, to the knowledge of the
Corporation, the Corporation is not threatened with, any Litigation or other
proceeding. Except as set forth in Schedule 4.13 hereto, there are no actions,
suits, proceedings, investigations or claims pending, or, to the knowledge of
the Corporation, threatened against the Corporation with respect to the
Business, the properties, operations, assets or affairs of the Corporation, at
law or in equity, before or by any federal, state, municipal or any other
governmental court, department, commission, agency or instrumentality, domestic
or foreign; nor, to the knowledge of the Corporation, is there any basis for any
such claim, suit, proceeding or investigation. The Corporation has not admitted
in writing its inability to pay its debts generally as they become due, filed or
consented to the filing against it of a petition in bankruptcy or a petition to
take advantage of any insolvency act, made an assignment for the benefit of
creditors, consented to the appointment of a receiver for itself or for the
whole or any substantial part of its property, or had a petition in bankruptcy
filed against it, been adjudicated a bankrupt, or filed a petition or answer
seeking reorganization or arrangement under the federal bankruptcy laws or any
other laws or of the United States or any other jurisdiction.

         4.14 TAXES. The Corporation has filed in proper form all federal,
state, local and foreign Tax (as such term is defined herein) returns required
to be filed prior to the date hereof, which relate to the Assets or to the
operations of the Business, and all such returns are true and correct. All
taxes, fees, assessments and charges due and payable by the Corporation on or
before the date hereof pursuant to said returns have been paid. There is no
unpaid interest, penalty or addition to tax due or claimed to be due from, or
any unpaid tax deficiency, determination or assessment
                                             
                                      -21-

<PAGE>

outstanding against the Corporation and there is no basis therefor. The Federal
income tax returns of the Corporation have never been audited by the Internal
Revenue Service. Neither the Internal Revenue Service nor any other taxing
authority is now asserting nor, to the best of the Corporation's knowledge and
belief, is threatening to assert, against the Corporation any deficiency or
claim for additional taxes or interest thereon or penalties in connection
therewith, and the Corporation does not know of any such deficiency or basis for
such a deficiency or claim.

         4.15 SECURITIES LAWS. Neither the Corporation nor anyone acting on its
behalf has offered securities of the Corporation for sale to, or solicited any
offers to buy the same from, or sold securities of the Corporation to, any
person or organization, in any case so as to subject the Corporation, its
promoters, directors and/or officers to any liability under the Securities Act
of 1933, as amended (the "Securities Act"), the Securities and Exchange Act of
1934, as amended, or any state securities or "blue sky" law (collectively, the
"Securities Laws").

         4.16 INVESTMENTS IN OTHER PERSONS. Except as indicated in Schedule
4.16, (a) the Corporation has not made any loan or advance to any person or
entity which is outstanding on the date hereof, nor is it committed or obligated
to make any such loan or advance, and (b) the Corporation has never owned or
controlled and does not currently own or control, directly or indirectly, any
subsidiaries and has never owned or controlled and does not currently own or
control any capital stock or other ownership interest, directly or indirectly,
in any corporation, association, partnership, trust, joint venture or other
entity.
         4.17 ERISA. The Corporation has not made and is not required to make
any contributions to any pension, defined benefit or defined contribution plans
for its employees which are subject to the Federal Employee Retirement Income
Security Act of 1974, as amended
    
                                      -22-

<PAGE>

("ERISA"). Except for the health insurance plan disclosed in Schedule 4.18
hereto (the "Benefit Plan"), the employees of the Corporation and independent
contractors who contract with the Corporation to perform services with respect
to the operation of the Business do not benefit under and are not covered by (as
a current employee or a future retiree) any employee benefit plan, as defined in
Section 3(3) of ERISA, or any other severance, bonus, salary continuation,
medical, disability, life, retirement, insurance, pension, profit-sharing,
deferred compensation plan, agreements or arrangements whether written or oral,
qualified or nonqualified, funded or unfunded, foreign or domestic, any trust,
escrow, or similar agreement related thereto, whether or not funded, nor has the
Corporation's shareholders, officers, or directors, taken any action directly or
indirectly to obligate the Corporation to institute any such employee plan. Any
Benefit Plan intended to be a qualified plan within the meaning of Sections
401(a) and 501(a) of the Internal Revenue Code of 1986, as amended (the "Code")
(the "Qualified Plans") has been determined by the Internal Revenue Service to
be so qualified. There is no fact or circumstance which would adversely affect a
Qualified Plan's qualified status or compliance as described above. The
Corporation has complied with all terms and conditions of, and (except as
disclosed on the balance sheets which are part of Schedule 4.07 hereto) have no
liabilities or obligations with respect to, a Benefit Plan, and (except as
disclosed on said balance sheets), all benefits relating to periods of service
under a Qualified Plan are fully funded. All (i) insurance premiums required
with respect to, (ii) benefits, expenses, and other amounts due and payable
under, and (iii) contributions, transfers, or payments required to be made to,
any Benefit Plan through the Closing Date will have been paid on or before the
Closing Date, and, with respect to any insurance policy (including any stop-loss
coverage) providing funding for benefits under any Benefit Plan, there is no
liability
                                                         
                                      -23-

<PAGE>

of the Corporation, in the nature of a retroactive rate adjustment, loss sharing
arrangement, or other actual or contingent liability, nor would there be any
such liability if such insurance policy was terminated on the date hereof. All
Benefit Plans have been maintained in full compliance with all laws, regulations
and orders, including, without limitation, ERISA and the Code, of all
governmental authorities, and all notices, reports and other filings required to
be delivered or filed under applicable law with respect to the Benefit Plans
have been duly and timely delivered or filed. The Corporation and the members of
any controlled group as defined in Section 414(b), (c), (m) and (o) of the Code
of which the Corporation is a member, have not incurred or taken any action, and
no action or event has occurred, that could be expected to cause the Corporation
or the Subsidiary to incur any liability (i) under Section 412 of the Code or
Title IV of ERISA with respect to any accumulated funding deficiency under any
employee benefit plan that is a single-employer plan, within the meaning of
Section 4001(a)(15) of ERISA, (ii) on account of a partial or complete
withdrawal as provided in Section 4201 or 4212 of ERISA from any multiemployer
plan, within the meaning of Section 3(37) of ERISA, or on account of any unpaid
contributions to any such multiemployer plan, (iii) for any tax or penalty under
Section 4975 of the Code or Section 502(i) of ERISA for any prohibited
transaction, within the meaning of Section 4975 of the Code or Section 406 of
ERISA, (iv) on account of a distress or involuntary plan termination under
Section 4062(b)(1) of ERISA, or (v) under Section 4980B of the Code or under
Sections 502 and 601 through 607 of ERISA on account of a failure to comply with
the continuation coverage requirements of the Consolidated Omnibus Budget
Reconciliation Act of 1985 ("COBRA"). The Corporation has complied in all
respects with the continuation coverage requirements of group health plans under
the Code, ERISA and state law applicable to a Benefit

Plan with respect to the transactions contemplated by this Agreement. No Benefit
Plan is a multiemployer plan within the meaning of Section 3(37) of ERISA or a
plan that is subject to Title IV of ERISA; the Corporation has not sponsored,
maintained, contributed to or been obligated to contribute to any such
multiemployer plan or plan subject to Title I of ERISA during the last six
years. The Subsidiary has been provided with true, correct and complete copies
of each of the Benefit Plans and any trust agreements relating to the Benefit
Plans and any other information relating to the Benefit Plans reasonably
requested by the Subsidiary.

hereto, the Corporation has not extended any offer or promise or entered into
any agreement, arrangement, understanding or otherwise, whether written or oral,

                                      -34-

<PAGE>

               (f) the Corporation  shall not lease or create a Lien against any
Assets, except for Liens for current taxes not yet due; and

               (g) the Corporation shall maintain in effect its existing

and are reasonably satisfactory to the Subsidiary.

         6.05 CONFIDENTIALITY. (a) Unless and until the Closing is consummated,
the Corporation shall keep confidential any information which has been furnished
to it by or on behalf of the Subsidiary in connection with the transactions
contemplated by this Agreement (the "Subsidiary Confidential Information"), and
shall use the Subsidiary Confidential Information solely in connection with the
transactions contemplated by this Agreement. In the event this Agreement is
terminated, the Corporation shall return all documents received from the
Subsidiary which contain Subsidiary Confidential Information to the Subsidiary
and shall destroy any writings made by or on behalf of the Corporation which
writings were based upon or contain any Subsidiary Confidential Information.
Subsidiary Confidential Information does not include information which: (i) is
or becomes (but only when it becomes) generally available to the public other
than as a result of disclosure in violation of this Section 6.05; or (ii) is or
becomes (but only when it becomes) available to the Corporation on a
non-confidential basis from a source other than the Subsidiary or its agents or
advisors, provided that such source is not bound by a confidentiality agreement
with the Subsidiary in respect thereof.

<PAGE>

                  (b) The Corporation may disclose the Subsidiary Confidential
Information to any of its directors, officers, employees, agents and advisors
who need to know such Subsidiary Confidential Information in connection with the
transactions contemplated by this Agreement; provided, however, prior to making
such disclosure, the Corporation shall inform all such persons and entities of
the confidential nature of such Subsidiary Confidential Information.
Notwithstanding the foregoing, the Corporation may disclose Subsidiary
Confidential Information if required by legal process or by operation of
applicable law (but only to the extent so required), provided that the
Corporation shall first promptly notify the Subsidiary thereof so that the
Subsidiary may seek an appropriate protective order.

                  (c) In the event that the transactions contemplated hereby are
consummated, from and after the Closing Date, the Corporation agrees to use its
best efforts to keep confidential any and all information and data with respect

information and data during the course of or in connection with any litigation,
arbitration or other proceeding based upon or in connection with the subject
matter of this Agreement; provided that the Corporation shall first promptly
notify the Subsidiary thereof so that the Subsidiary may seek an appropriate
protective order.

                  (d) Without intending to limit the remedies available to the
Subsidiary due to any breach of this Section 6.05, the Corporation agrees that
damages at law would be an insufficient remedy to the Subsidiary in the event of
any breach by the Corporation of this Section 6.05 and that the Subsidiary shall
be entitled to injunctive relief or other equitable remedies in the event of any
such breach.

         6.06 NOTICE OF ACTIONS AND PROCEEDINGS. The Corporation shall promptly
notify the Subsidiary of any actions, suits, claims, investigations or
proceedings commenced or, to the Corporation's knowledge, threatened against,
relating to or involving or otherwise affecting the Corporation which, if
pending on the date hereof, would have been required to have been disclosed in
writing pursuant to Sections 4.04 or 4.13 hereof or which relate to the
consummation by the Corporation of the Closing.

         6.07 CHANGE OF NAME. The Corporation hereby agrees that immediately
after the Closing it shall take all actions and make all filings required under
the laws of the State of Colorado and the laws of any other jurisdiction in
which it is qualified to transact business, in order to change its name to

trademark or servicemark used by the Corporation and shall coordinate the taking
of such actions and the making of such filings with the Subsidiary and its
counsel.

         6.08 COVENANT NOT-TO-COMPETE. The Corporation agrees that during a five
(5) year period commencing on the Closing Date ("the Term"), it will not,
directly or indirectly:

         (a) on its own account or as agent, stockholder, partner, owner,
employer, employee (or otherwise) of another solicit any business which is the
same or similar or competitive with that of the Subsidiary (including, without
limitation, with respect to the Business) from the customers of the Subsidiary
on the date hereof or thereafter during the Term; or

          (b)  engage  in a  business  which is the same or  similar  to or
competitive  with that of the  Subsidiary  (or any  subsidiaries  or affiliates)
(including,   without  limitation,  the  Business)  in  the  Territory  (defined
hereinafter). "Territory" means the United States; or
                                                                
                                      -37-

<PAGE>

         (c) contact or approach, directly or indirectly, for its own individual
purposes or those of another, any employee of the Subsidiary, without regard to
his or her location, for the purpose of attempting to or actually soliciting or
hiring that employee on its own account, or for the account of another; or

         (d) acquire any ownership interest in or lend money to (or act as a
guarantor or surety in connection with a loan by a third party to) any person,
partnership, corporation or other entity engaged in any business (or subsidiary
or division) referred to in clause (b) above; provided however, that the
limitation contained in this clause (d) shall not apply to the ownership of less
than five percent (5%) of the voting stock of a publicly held company.

         The parties agree that no adequate remedy at law exists for the
violation of the covenants contained in this Section and that such covenants
shall be enforceable by specific performance and injunctive relief or at law in
an action for damages at the election of the Subsidiary. If any court, in an
unappealed final decision, holds that the restrictions on competition provided
for in this Section are too broad in scope as to area, activity or time period
covered thereby, such area, activity or time period may be reduced to the extent
such court deems reasonable. The parties agree that they shall be bound by the
terms of such lesser covenant held by that court to be reasonable and
enforceable.

         The parties hereto hereby acknowledge and agree that (i) the Subsidiary
would be irreparably injured in the event of a breach by the Corporation of any
of its obligations under this Section, (ii) monetary damages would not be an
adequate remedy for any such breach, and (iii) the Subsidiary shall be entitled
to injunctive relief, in addition to any other remedy which it may have, in the
event of any such breach. It is hereby also agreed that the existence of any
claims
                                      -38-

<PAGE>

which the Corporation may have against the Subsidiary, whether under this
Agreement or otherwise, shall not be a defense to the enforcement by the
Subsidiary of any of its rights under this Section.

         The undertakings of the Corporation contained in this Section shall be
in addition to, and not in lieu of, any obligations which it may have with
respect to the subject matter hereof, whether by contract, as a matter of law or
otherwise.

CONFIDENTIALITY. (a) Unless and until the Closing is consummated, the Subsidiary
shall keep  confidential any information which has been furnished to it by or on
behalf of the  Corporation in connection with the  transactions  contemplated by
this Agreement (the "Corporation Confidential  Information"),  and shall use the
Corporation  Confidential Information solely in connection with the transactions
contemplated by this Agreement.  In the event this Agreement is terminated,  the

Corporation Confidential Information. Corporation Confidential Information does
not include information which: (i) is or becomes (but only when it becomes)
generally available to the public other than as a result of disclosure in
violation of this Section 7.02; or (ii) is or becomes (but only when it becomes)
available to the Subsidiary on a non-confidential basis from a source other than
the Corporation or its agents or advisors, provided that such source is not
bound by a confidentiality agreement with the Corporation in respect thereof.

                  (b) The Subsidiary may disclose Corporation Confidential
Information to any of its directors, officers, employees, agents, advisors and
prospective lenders who need to know such Corporation Confidential Information
in connection with the transactions contemplated by this Agreement; provided,
however, prior to making such disclosure, the Subsidiary shall inform all such
persons and entities in writing of the confidential nature of such Corporation
Confidential Information. Notwithstanding the foregoing, the Subsidiary may
disclose Corporation Confidential Information if required by legal process or by
operation of applicable law (but only to the extent so required), provided that
the Subsidiary shall first promptly notify the Corporation thereof so that the
Corporation may seek an appropriate protective order.

                  (c) Without intending to limit the remedies available to the
Corporation due to any breach of this Section 7.02, the Subsidiary agrees that
damages at law would be an insufficient remedy to the Corporation in the event
of any breach by the Subsidiary of this Section 7.02 and that the Corporation
shall be entitled to injunctive relief or other equitable remedies in the event
of any such breach.

               7.03 FURTHER ASSURANCES.  At any time and from time to time after
the Closing  Date,  the  Subsidiary  shall,  at the request of the  Corporation,
execute and deliver any further instruments

or documents and take all such further action as the Corporation may reasonably
request in order to consummate more effectively the transactions contemplated
hereby and the assumption of the Assumed Liabilities by the Subsidiary.

contesting any third party claim or demand. Whether or not the indemnifying
party so elects to defend any such claim or demand, the indemnified party shall
not have any obligation to do so and the indemnified party shall not be deemed

         Agreement, Quintiles and its employees may be exposed to data and
         information which is confidential and proprietary to Interneuron. All
         such data and information (hereinafter "Interneuron Confidential
         Information") written or verbal, tangible or intangible, made
         available, disclosed, or otherwise made known to Quintiles and its

         result of a disclosure by the receiving party;

         (b) becomes available to the receiving party on a non-confidential
         basis from a source which is not prohibited from disclosing such
         information by a legal, contractual or fiduciary obligation to the
         disclosing party;

         (c) the receiving party develops independently of any disclosure by
         the disclosing party;

         assignments will be forwarded by Interneuron to Quintiles. All data and
         information generated or derived by Quintiles as the result of services
         performed by Quintiles under this Agreement shall be and remain the
         exclusive property of Interneuron. Any inventions that may evolve from

         receive any royalties  payable  under  Section 18 hereof.  (b) Upon the
         termination  of  the  Employee's  employment  hereunder  pursuant  to a
         Termination Without Cause,  neither the Employee nor his beneficiary or

         under this Agreement  except to receive a termination  payment equal to
         that provided for in Section  10(a) hereof,  plus the amounts set forth

consolidation,   transfer  of  all  or  substantially  all  assets,  or
otherwise and the heirs and legal representatives of the Employee.

         18. ADDITIONAL CONSIDERATION. As further consideration for this
Agreement, the Corporation agrees to pay to the Employee a royalty of one
quarter of one percent (.25%) of Net Sales of products sold by the Corporation
and based on or derived from a method to treat disease by stimulating cellular
immunity ("Products"), which technology has been transferred to the Corporation
by Innovative Therapeutics, Inc. ("ITI") by a separate agreement of even date
herewith (the "Transferred Technology"). For purposes of this provision Net
Sales shall mean the total amount received from the sale of Products by the
Corporation or its affiliates or sublicensees less transportation charges and
insurance, sales taxes, use taxes, excise taxes, value added taxes, customs
duties or other imposts, normal and customary quantity and cash discounts,
rebates granted and disallowed reimbursements and allowances and credit on
account of rejection or return of Products. Such royalties will be paid from
first commercial sale of the first Product subject to royalty herein so long as
such Product is covered by a valid claim of an issued patent of the Corporation
in the country where sold.

         19. OPTION. In addition in the event the Corporation determines to
totally abandon its interest in the Transferred Technology, the Employee is
hereby granted an exclusive option to exclusively license such Transferred
Technology from the Corporation for a payment to the Corporation of two hundred
fifty thousand dollars ($250,000) and payment to the Corporation of royalties
equivalent to the royalties to the Employee described in Paragraph 18 above.
Such option may only be exercised by written notice from the Employee to the
Corporation within sixty (60) days of the Corporation notifying the

J:\DOCS\BTPM_NY_\1063\0053262.01

                                      -10-

<PAGE>

Employee of its total abandonment of the Transferred  Technology or the
expiration of the six (6) month period set forth below, whichever is earlier. If
such option is not so exercised  within said period,  the option shall lapse and
terminate. If such option is exercised,  the Employee shall have sixty (60) days
from the date such option is exercised to close, including,  without limitation,
to pay the $250,000 sum described  above.  If the closing shall not occur within
said  period,  the exercise of the option shall be void and of no effect and the
option shall lapse and terminate. For purposes of this provision the Corporation
will be  deemed  to have  totally  abandoned  its  interest  in the  Transferred
Technology at such time as it has made a good faith  scientific  judgment that a
commercial  product cannot be developed from such  technology  and/or it has not
conducted any research or development  activities  with respect to any aspect of
the  technology  for at least six (6) months,  including but not limited to, the
failure to fund such activities for at least six (6) months.

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