Seller of this Agreement, the consummation of the transactions contemplated
hereby and compliance by such Seller with the terms hereof will not (a) violate,
conflict with, cause an event of default under, give rise to a right of

authority to execute this Agreement and to consummate the transactions
contemplated hereby and thereby. This Agreement has been duly executed and
delivered by such Seller. The execution and delivery of this Agreement by the

Agreement constitutes a valid and binding obligation of such Seller, enforceable
against such Seller in accordance with its terms subject to applicable
bankruptcy, insolvency, moratorium and other similar laws relating to the

            (b) The Company is not and has never been (i) a member of a
"controlled group of companies," under "common control" or an "affiliated
service group" within the meaning of Sections 414(b), (c) or (m) of the Code,
(ii) required to be aggregated under Section 414(o) of the Code, or (iii) under

to the Closing Date, maintained substantially in accordance with its terms and
in compliance in all material respects with all applicable laws, statutes,
orders, rules and regulations, including, without limitation, ERISA and the

exist that could reasonably be expected to give rise to, any requirement for the
posting of security with respect to a Benefit Plan or Employee Agreement or the
imposition of any Lien on the assets of the Company under applicable law,
including, without limitation, ERISA and the Code.

            (f) Except as set forth on Schedule 2.10, the execution of, and
performance of the transactions contemplated by, this Agreement will not (either
alone or upon the occurrence of any additional or subsequent events directly
related to the transactions contemplated by this Agreement) constitute an event
under any Benefit Plan or Employee Agreement that will or may result in any
payment, acceleration, forgiveness of indebtedness, vesting, distribution,
increase in benefits or obligations to fund benefits with respect to any
employee or former employee or any spouse or dependent thereof.

                                   ARTICLE III

                 Representations and Warranties of the Purchaser

            The Purchaser represents and warrants to the Sellers as follows:

            3.1 Organization; Standing and Power; Business of the Purchaser. The
Purchaser is a corporation duly organized, validly existing and in good standing
under the laws of the State of New York, with all requisite corporate power and
authority and all governmental licenses, authorizations, consents and approvals
required to own its properties and to conduct its business as presently
conducted and as presently proposed to be conducted. The Purchaser has delivered

The business of the Purchaser consists solely of the business described on
Schedule 3.1 hereto and related activities (the "Medscape Business").

            3.2 No Conflicts. The execution, delivery and performance by the
Purchaser of this Agreement, the consummation of the transactions contemplated
hereby and compliance by the Purchaser with the terms hereof will not (a)
violate, conflict with, cause an event of default under, give rise to a right of
termination, cancellation or acceleration of any right or obligation of the
Purchaser under, or result in the creation or imposition of any Lien on any
asset of the Purchaser or on any Shares under any agreement, instrument,
License, franchise, judgment, order, law, rule or regulation by which the
Purchaser is bound or to which the Purchaser's property is subject, nor (b)

   31

            3.3 Capitalization.

            The capitalization of the Purchaser is as set forth on Schedule 3.3
hereto. Except for the obligations set forth in this Agreement or as set forth
on Schedule 3.3, no party has any right or obligation to purchase or sell, or
any option or similar right to purchase, any security of the Purchaser. Other
than this Agreement or as set forth on Schedule 3.3, there are no outstanding
subscriptions, rights, options, warrants, conversion rights, agreements or other
claims for the purchase or acquisition from the Purchaser or any securities of
the Purchaser or obligating the Purchaser to issue, repurchase or otherwise
acquire any securities of the Purchaser or any securities convertible into,
exercisable or exchangeable for, or otherwise entitling the holder to acquire
any securities of the Purchaser. The Shares which constitute the In Kind
Purchase Price represent, on a fully diluted basis as of the date hereof, ten
(10%) percent of the shares of capital stock of the Purchaser. For these
purposes "fully diluted" is calculated assuming that all shares of the
Purchaser's preferred stock are converted into shares of the Purchaser's common
stock at the applicable conversion ratio, all outstanding stock options are
exercised and options to purchase all additional shares of the Purchaser's
common stock currently reserved under the Medscape Stock Award Plan are made and
such options are exercised but excluding the restricted shares described in
Section 5.1(f) below. The issuance of the Shares will not trigger any
"antidilution" provision of any existing security of the Purchaser.

            3.4 Due Authorization of the Shares. The issuance, sale and delivery
of the Shares pursuant to this Agreement have been duly authorized by all
requisite corporate action on the part of the Purchaser and when issued, sold
and delivered in accordance with this Agreement, the Shares will be validly
issued and outstanding, fully


                                       25

   32

paid and non-assessable, free and clear of all Liens, restrictions, encumbrances
and rights of others of any kind other than those created or permitted by the
Sellers.

            3.5 Binding Effect. The Purchaser has all requisite power and
authority to execute this Agreement and to consummate the transactions
contemplated hereby and thereby. This Agreement has been duly executed and
delivered by the Purchaser. The execution and delivery of this Agreement by the
Purchaser and the consummation of the transactions contemplated hereby by the
Purchaser do not and will not require the approval of any other party. Assuming
the due execution and delivery of this Agreement by the Sellers, this Agreement
constitutes a valid and binding obligation of the Purchaser, enforceable against
the Purchaser in accordance with its terms subject to applicable bankruptcy,
insolvency, moratorium and other similar laws relating to the enforcement of
creditor's rights generally, the availability of equitable remedies and to
general equity principles.

            3.6 Other Equity Interests. The Purchaser does not have, and has not
had at any time, any direct or indirect equity interest in any other
corporation, partnership, joint venture, limited liability company or other

circumstances exist that could reasonably be expected to give rise to, any
requirement for the posting of security with respect to a Medscape Benefit Plan
or Medscape Employee Agreement or the imposition of any Lien on the assets of
the Purchaser under applicable law, including, without limitation, ERISA and the
Code.

distribution, increase in benefits or obligations to fund benefits with respect
to any employee or former employee or any spouse or dependent thereof.

with the Purchaser would include those matters which are the subject of the
representation and warranty.

                                    Covenants

            4.1 The Sellers' Confidentiality Obligations. The Sellers
acknowledge that from and after the Closing, the Purchaser will have a
legitimate and continuing proprietary interest in the protection of trade
secrets and confidential information, knowledge and data of the Company and any
similar information with respect to the Purchaser (collectively, the
"Confidential Information") which is provided to any Seller. Except as
disclosure may be ordered by a Governmental Entity of competent jurisdiction or
as otherwise required by law, each Seller severally agrees that such Seller and
such Seller's Affiliates will maintain and cause to be maintained the
confidentiality of all Confidential Information related to the Business or the
Medscape Business, the Company or the Purchaser or any of its Affiliates, which
is held by or


                                       36

   43

known to any of them and shall not disclose the Confidential Information to any
person. In the event that any Seller or any of such Seller's Affiliates is
notified that he, she or it is or may become legally compelled to disclose any
of the Confidential Information, such Seller will provide the Purchaser with
prompt written notice of the existence, terms and circumstances surrounding such
notice so that the Purchaser may, at its cost and expense, seek a protective
order or other appropriate remedy. In the event that such protective order or
other remedy is not obtained prior to the time disclosure is required, the
Sellers will furnish only that portion of the Confidential Information that they
are advised in writing by counsel is legally required to be furnished, and will
furnish to the Purchaser a copy of such written advice of counsel. The Sellers
and their Affiliates shall not use any Confidential Information for any of their
benefit or the benefit of any other person. Information, knowledge or data shall
not be deemed to be Confidential Information to the extent that it is or becomes
generally available to the public other than as a result of disclosure by a
Seller or any of Seller's Affiliates, or becomes available to the Sellers on a
nonconfidential basis from a source other than the Company or the Purchaser or
any of its Affiliates or is known to a Seller prior to its disclosure to such
Seller by the Company or the Purchaser or any of its Affiliates.

            4.2 No Solicitation of Employees or Consultants, Non-Interference.

States and its territories and possessions, or in any other geographical area in
which the Purchaser has an office or a client (the "Medscape Territory"),

a business which is directly competitive


                                       37

   44

with the Purchaser, without the prior written consent of the Purchaser (i)
persuade or attempt to persuade any customer of the Purchaser or its affiliates
as of the date of the termination of his employment, to cease doing business

affiliates or solicit the business of any of the Purchaser's or its affiliates'

solicit or encourage to leave the employ of the Purchaser or its affiliates, or
to become employed by any person other than the Purchaser, any employee of the
Purchaser or its affiliates, or any individual who was an employee of the
Purchaser or its or affiliates during the one year prior to the termination of
his employment with the Purchaser. Jeffrey Drezner, M.D., Ph.D., agrees that for
the period during which he shall be in the Purchaser's employ and for a period
of six months after the termination of such employment for any reason
whatsoever, he will not, within the Medscape Territory, directly or indirectly,
on his own behalf or on behalf of anyone else engaged in a business which is
directly competitive with the Purchaser, without the prior written consent of
the Purchaser's, employ any employee of the Purchaser or its affiliates, or any
individual who was an employee of the Purchaser or its affiliates during the
three month period prior to the termination of his employment. Jeffrey Drezner,
M.D., Ph.D., acknowledges and agrees that the restrictions and obligations
imposed on him or her by virtue of this Section 4.2 are, in light of the
circumstances, fair and reasonable as to type, scope and period of time, and are
reasonably required for the protection of the Purchaser and the goodwill
associated


                                       38

   45

with the business of the Purchaser. It is the intent Jeffrey Drezner, M.D.,
Ph.D., and the Purchaser that this Agreement be enforceable and restrict the
Purchaser's activities only to the extent permitted by applicable law.
Therefore, if any provision of this Section 4.2 as presently written shall be
construed to be illegal, invalid or unenforceable by a court of competent
jurisdiction, said illegal, invalid or unenforceable provision shall be deemed
to be amended and shall be construed by the court to have the broadest type,
scope and duration permissible under applicable law, and if no validating
construction is possible, shall be severable from the rest of this Agreement,
and the validity, legality or enforceability of the remaining provisions of this
Agreement shall not in any way be affected or impaired thereby.

            4.3 Taxes. The Sellers shall be liable for any obligation or
liability of the Company or the Sellers for transfer or sales taxes or other
taxes attributable to, arising from or associated with the sale or transfer from
the Sellers to the Purchaser of the Interests and the Sellers shall prepare and
file all required returns relating to such taxes.

            4.4 Covenant Not to Compete. Jeffrey Drezner, M.D., Ph.D., agrees
that for the period during which he shall be in the Purchaser's employ and for a
period of one year after the termination of such employment for any reason
whatsoever, he shall not, whether as an owner, shareholder (other than in his
capacity as holder of less than 2% of the shares of any corporation whose shares
are traded on a national securities exchange or over the counter which shall be
excepted from this restriction), partner, employee, consultant, advisor,
independent contractor or otherwise, directly or indirectly compete with the
business of the Purchaser in any manner. Jeffrey Drezner, M.D., Ph.D.,
acknowledges and agrees that the restrictions and obligations imposed on


                                       39

   46

him by virtue of this Section 4.4 are, in light of the circumstances, fair and
reasonable as to type, scope and period of time, and are reasonably required for
the protection of the Purchaser and the goodwill associated with the business of
the Purchaser. It is the intent of Jeffrey Drezner, M.D., Ph.D., and the
Purchaser that this Agreement be enforceable and restrict Jeffrey Drezner, M.D.,
Ph.D.'s, activities only to the extent permitted by applicable law. Therefore,
if any provision of this Section 4.4 as presently written shall be construed to
be illegal, invalid or unenforceable by a court of competent jurisdiction, said
illegal, invalid or unenforceable provision shall be deemed to be amended and
shall be construed by the court to have the broadest type, scope and duration
permissible under applicable law, and if no validating construction is possible,
shall be severable from the rest of this Agreement, and the validity, legality
or enforceability of the remaining provisions of this Agreement shall not in any
way be affected or impaired thereby.

            4.5 Tax Matters. The following provisions shall govern the
allocation of responsibility as between the Purchaser and the Sellers for
certain Tax matters following the Closing Date:

            (a) Tax Periods Ending on or Before the Closing Date. The Sellers
shall prepare, at the Company's expense, all Tax returns for the Company for all
periods ending on or prior to the Closing Date which are due after the Closing
Date, such returns to be prepared in a manner consistent with prior years. The
Purchaser (or, if required by law, the Sellers) shall timely file or shall cause
the Company to timely file such Tax returns (if timely prepared by the Sellers),
provided that the Sellers shall be liable for any and all Taxes actually due and
payable with respect to any period prior to


                                       40

   47

January 1, 1998 to the extent such liability was not accrued and reflected on
the HCG Interim Balance Sheet or otherwise set forth in the Schedules attached
hereto.

            (b) Tax Periods Beginning Before and Ending After the Closing Date.
The Purchaser shall prepare or cause to be prepared and file or cause to be
filed any Tax returns of the Company for Tax periods which begin before the
Closing Date and end after the Closing Date. The Sellers shall pay to the
Purchaser not later than fifteen (15) days prior to the date such Taxes are due
with respect to such periods an amount equal to the portion of such Taxes
actually due and payable with respect to the portion of such Taxable period
ending on December 31, 1997 to the extent such Taxes were not accrued and
reflected on the HCG Interim Balance Sheet. For purposes of this Section, in the
case of any Taxes that are imposed on a periodic basis and are payable for a
Taxable period that includes (but does not end on) December 31, 1997, the
portion of such Tax which relates to the portion of such Taxable period ending
on December 31, 1997 shall (x) in the case of any Taxes other than Taxes based
upon or related to income or receipts, be deemed to be the amount of such Tax
for the entire Taxable period multiplied by a fraction the numerator of which is
the number of days in the Taxable period ending on the Closing Date and the
denominator of which is the number of days in the entire Taxable period, and (y)
in the case of any Tax based upon or related to income or receipts be deemed
equal to the amount which would be payable if the relevant Taxable period ended
on December 31, 1997. Any credits relating to a Taxable period that begins
before and ends after December 31, 1997 shall be taken into account as though
the relevant Taxable period ended on December 31, 1997.


                                       41

   48

                  (i) The Purchaser, the Company and the Sellers shall cooperate
            fully, as and to the extent reasonably requested by the other party,
            in connection with the filing of Tax returns pursuant to this
            Section and any audit, litigation or other proceeding with respect
            to Taxes. Such cooperation shall include the retention and (upon the
            other party's request) the provision of records and information
            which are reasonably relevant to any such audit, litigation or other
            proceeding and making employees available on a mutually convenient
            basis to provide additional information and explanation of any
            material provided.

                  (ii) The Purchaser and the Sellers further agree, upon
            request, to use their commercially reasonable efforts to obtain any
            certificate or other document from any governmental authority or any
            other Person as may be necessary to mitigate, reduce or eliminate
            any Tax that could be imposed (including, but not limited to, with
            respect to the transactions contemplated hereby). 

            (d) Notification of Inquiry. If the Purchaser or the Company becomes
aware of any assessment, official inquiry, examination or proceeding that could
result in an official determination with respect to Taxes due or payable for any
Taxable year or Tax period ending on or before the Closing Date, the Purchaser
shall promptly notify the Sellers in writing and shall permit the Sellers to
participate at their own expense in any such official inquiry, examination or
proceeding. If the Sellers become aware of any official inquiry, examination or
proceeding that could result in an official determination with respect to Taxes
due or payable by the Company, the Sellers shall


                                       42

   49

promptly so notify the Purchaser in writing and shall permit the Purchaser and
the Company to participate at their own expense in any such official inquiry,
examination or proceeding.

                                 Indemnification

            6.1 Indemnification by Sellers.

            (a) Subject to the limitations set forth in this Agreement, each of
the Sellers jointly and severally, agrees promptly to indemnify, defend and hold
harmless the Purchaser from and against any and all assessments, judgments,
debts, obligations, liabilities, losses, costs, damages or expenses (including
interest, penalties and reasonable out-of-pocket fees, expenses and
disbursements in connection with any action, suit or proceeding) net of
insurance proceeds actually received (collectively, "Damages"), suffered, paid
or incurred by the Purchaser or the Company resulting from or caused by or
arising out of any breach of the representations and warranties made by any
Seller to the Purchaser in this Agreement or in any Schedule hereto or any
certificate delivered hereunder (provided; that liability for the
representations and warranties in Section 2.4 and 2.5, which are made severally,
rather than jointly and severally, shall be several). In addition, each of the
Sellers severally agrees promptly to indemnify, defend and hold harmless the
Purchaser from and against any and all Damages suffered, paid or incurred by the
Purchaser or the Company resulting from or caused by or arising out of any
failure by such Seller to perform any of his or her covenants or agreements
contained in this Agreement.


                                       45

   52

            (b) Notwithstanding anything contained in this Agreement to the
contrary, indemnification under Section 6.1(a) is subject to the limitations
that (i) the aggregate amount of all payments required to be made by any Seller
in satisfaction of claims for indemnification pursuant to Section 6.1(a) shall
not exceed the portion of the Cash Purchase Price paid and the then fair market
value of the Shares delivered to him and (ii) no claim for indemnification may
be made until and thereafter only to the extent that the aggregate of Damages
for which the Sellers would otherwise be liable exceeds $75,000.

            6.2 Indemnification by the Purchaser.

            (a) The Purchaser agrees to indemnify and hold harmless the Sellers
from and against any and all Damages suffered, paid or incurred by any Seller
resulting from or caused by or arising out of: (i) any breach of the
representations and warranties made by the Purchaser in this Agreement or any
certificate delivered hereunder and (ii) any failure by the Purchaser to perform
any covenant or agreement of the Purchaser contained in this Agreement.

            (b) Notwithstanding anything contained in this Agreement to the
contrary, that (i) the aggregate of all payments to be made by the Purchaser in
satisfaction for claims for indemnification pursuant to this Section 6.2 shall
not exceed the aggregate value of the Cash Purchase Price and the then fair
market value of the Shares and (ii) no claim for indemnification may be made
until and thereafter only to the extent that the aggregate amount of Damages for
which the Purchaser would otherwise be liable exceeds $75,000.

            6.3 Indemnity Procedure for Third Party Claims.


                                       46

   53

            Promptly after receipt by a party seeking indemnification hereunder
(an "Indemnified Party") of notice of any claim or the commencement by any third
party of any action, suit or proceeding which might result in the other party
hereto (the "Indemnifying Party") becoming obligated to indemnify or make any
other payment to the Indemnified Party under this Agreement, the Indemnified
Party shall notify the Indemnifying Party forthwith in writing of the
commencement thereof or of the claim, and shall furnish the Indemnifying Party
with all information and documents relating thereto promptly after its receipt
thereof. The failure of the Indemnified Party to so notify the Indemnifying
Party shall not relieve the Indemnifying Party from any liability which it may
have on account of this indemnification or otherwise, except and only to the
extent that the Indemnifying Party is materially prejudiced thereby. The
Indemnifying Party shall have the right, within thirty (30) days after being so
notified, to assume and control the defense of such claim, litigation or
proceeding with counsel reasonably satisfactory to the Indemnified Party in good
faith and at the Indemnifying Party's own expense; provided that unless and
until the Indemnifying Party shall assume such defense pursuant to this
sentence, the Indemnified Party shall have the right to conduct and control the
defense of such claim, litigation or proceeding (including the settlement
thereof) without the Indemnifying Party's consent and shall be entitled to
payment from the Indemnifying Party of all reasonable costs of such defense
(including attorney's fees and expenses). In any such claim, litigation or
proceeding the defense of which the Indemnifying Party shall have so assumed,
the Indemnified Party shall have the right to participate therein and retain its
own counsel at its own expense, unless (i) the Indemnifying Party and the
Indemnified Party shall have mutually agreed to the retention of the same
counsel or (ii) the named parties to any such litigation or

                                       47

   54

proceeding (including impleaded parties) include both the Indemnifying Party and
the Indemnified Party, and representation of such parties by the same counsel
would be inappropriate due to actual or potential differing interests between
them; in the case of clause (ii) above, such separate counsel may be retained by
the Indemnified Party at the expense of the Indemnifying Party. The Indemnifying
Party may elect to settle any claim, action or proceeding defended by it without
the written consent of the Indemnified Party provided that such settlement is
limited to payment of monetary damages which are payable in full by the
Indemnifying Party and the Indemnified Party is fully discharged at the time of
the settlement from any liability with respect to the claim, action or
proceeding, and the Indemnified Party shall not admit any liability with respect
thereto or settle, compromise, pay or discharge the same without the prior
written consent of the Indemnifying Party so long as the Indemnifying Party is
controlling or defending such claim in good faith. The Indemnifying Party may
not enter into any settlement that is not limited to payment of monetary damages
without the Indemnified Party's prior written consent which will not be
unreasonably withheld. Each of the Sellers and the Purchaser covenant to use all
reasonable efforts to cooperate fully with respect to the defense of any claim,
action or proceeding covered by this Section 6.3.

            6.4 Tax Indemnification.

            (a) Notwithstanding any limitation on indemnification set forth in
Section 6.1 or 6.3 of the Agreement and without regard to any other limitation
on liability set forth in the Agreement, after the Closing Date, the Sellers,
jointly and severally, will fully indemnify, defend and hold harmless the
Purchaser from and against any and all Damages resulting from, arising out of or
relating to Taxes for periods ending on or


                                       48

   55

before December 31, 1997, or for any Taxes not disclosed in Schedule 2.8,
imposed on the Company for, or resulting from the denial of any deduction or
credit claimed for, any taxable period ending on or before the Closing Date.

            (b) This Section 6.4 shall remain in force for the period described
in Section 7.6 of the Agreement.

            6.5 Waiver of Right to Contribution. Each Seller hereby waives,
effective as of the Closing Date, any rights which such Seller may have against
the Company in connection with any contribution or indemnification for payments
made after the Closing Date pursuant to this Agreement or otherwise.

            6.6 Sole Remedy. In the event of a breach of a representation or
warranty or covenant hereunder, the remedy of the beneficiary of such
representation or warranty or covenant shall be limited solely to the indemnity
set forth in this Article VI.

                                   ARTICLE VII

                                  Miscellaneous

            7.1 Expenses. Except as provided below, each party will pay all of
his, her or its own expenses in connection with the negotiation of this
Agreement, the performance of his, her or its obligations hereunder and the
consummation of the transactions contemplated hereby. The Sellers shall not
charge any such expenses to the Company. Purchaser shall reimburse one-half of
the Sellers' legal expenses payable to Goodwin, Procter & Hoar LLP in connection
with the negotiation and documentation of the transaction contemplated hereby
and by the Drezner Employment Agreement up to a maximum total reimbursement of
$25,000.

            7.2 Interpretation. When a reference is made in this Agreement to a
Section, Schedule or Exhibit, such reference shall be to a Section, Schedule or
Exhibit of this Agreement unless otherwise indicated. The table of contents
contained in this Agreement is for reference purposes only and shall not affect
in any way the meaning or interpretation of this Agreement. Whenever the words
"included," "includes" or "including" are used in this Agreement, they shall be
deemed to be followed by the words "without limitation." All accounting terms
not defined in this Agreement shall have the meanings determined by GAAP.

            7.3 Further Assurances. Each of the parties hereto covenants and
agrees to take any and all such further action and to execute, acknowledge and
deliver such instruments, documents and agreements as any other party may
reasonably request to effectuate, consummate or confirm the transactions
contemplated hereby.

            7.4 Amendment and Waiver. This Agreement may be amended only in a
writing signed by the Sellers' Representative and the Purchaser. Any provision
of this Agreement may be waived by the party entitled to the benefit thereof
only in a writing executed by the party against whom such waiver is sought to be
enforced. No waiver shall be deemed a waiver of any other provision of this
Agreement, and no waiver of a breach hereunder shall be deemed a waiver of any
other or subsequent breach of this Agreement.

            7.5 Notice. All notices, demands and other communications to be
given or delivered hereunder shall be in writing and will be deemed to have been
given if personally delivered or sent by overnight courier (in each such case

(Capitalization) which shall survive indefinitely and Section 2.8 and Section
3.8 (Taxes), and 2.10 and 3.10 (Labor and Employee Benefit Matters) which shall

warranty. Those covenants contained in this Agreement that contemplate or may
involve actions to be taken or obligations in effect after the Closing Date
shall survive the Closing Date until the expiration of the applicable statute of
limitations.

            7.7 Binding Agreement; Assignment. This Agreement and all of the
provisions hereof will be binding upon and inure to the benefit of the parties
hereto and their respective successors. The Sellers may not assign their rights
or delegate their duties hereunder without the prior written consent of the
Purchaser, which consent may be granted, withheld or conditioned in the sole and
absolute discretion of the Purchaser. The Purchaser may not assign its rights or
delegate its duties hereunder, whether by operation of law or otherwise, to any
non-affiliated third party, without the prior written consent of the Sellers'
Representative, which consent may be granted, withheld or conditioned in the
sole and absolute direction of the Sellers' Representative.

            7.8 Severability. Whenever possible, each provision of this
Agreement will be interpreted in such a manner as to be effective and valid
under applicable law,


                                       52

   59

but if any provision of this Agreement is held to be prohibited by or invalid
under applicable law, such provision will be ineffective only to the extent of
such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Agreement.

            7.9 Captions. The captions used in this Agreement are for
convenience of reference only and do not constitute a part of this Agreement and
will not be deemed to limit, characterize or in any way affect any provision of
this Agreement and all provisions of this Agreement will be enforced and
construed as if no captions had been used in this Agreement.

            7.10 Counterparts. This Agreement may be executed in two or more
counterparts, each of which need not contain signatures of more than one party,
but all such counterparts taken together will constitute one and the same
instrument. Signatures may be exchanged by telecopy, with original signatures to
follow. Each party to this Agreement agrees that it will be bound by his, her or
its own telecopied signature and that he, she or it accepts the telecopied
signatures of the other parties to this Agreement.

            7.11 Governing Law. This Agreement shall be governed by, construed
and enforced in accordance with the laws of the State of New York, without
reference to the choice of law provisions thereof. Any legal action or
proceeding with respect to this Agreement or any transaction related hereto
shall be brought in the courts of the State of New York or of the United States
District Court for the Southern District of New York, and, by the execution and
delivery of this Agreement, each of the parties hereto hereby consents for
himself, herself and itself and in respect of his, her or its property to the
exclusive jurisdiction of the aforesaid courts and agrees that service of
process in any


                                       53

   60

legal action or proceeding with respect to this Agreement or any transaction
related hereto may be made on such party by delivery of such process by
certified mail, return receipt requested, to such party at its address for
notice pursuant to Section 7.5 of this Agreement with the same effect as if such
process was personally served on such party within the State of New York. Each
of the parties hereto hereby irrevocably waives, to the extent permitted by
applicable law, any objection, including, but not limited to, any objection to
the laying of venue or based on the ground of forum non conveniens, which he,
she or it may now or hereafter have to the bringing of any action or proceeding
in such jurisdictions in respect of this Agreement or any transaction related
hereto. Nothing contained herein shall affect the right of any party hereto to
serve process in any other manner permitted by law.

            7.12 Remedies. All rights, remedies or powers hereby conferred
shall, to the extent not prohibited by law, be deemed cumulative and not
exclusive of any other thereof, or of any other rights, remedies or powers
available. No single or partial exercise of any right, remedy or power by a
party shall preclude further exercise thereof. No delay or omission to exercise
any right, power or remedy accruing to a party upon the occurrence of any breach
of any warranty, covenant or agreement contained in this Agreement shall impair
any such right, power or remedy or be construed to be a waiver of any such
breach or any acquiescence therein or to any similar breach thereafter
occurring. In addition to such other rights and remedies as the Purchaser may
have at equity or in law with respect to any breach of this Agreement, if
Jeffrey L. Drezner, M.D., Ph.D. commits a material breach of any of the
provisions of Sections 4.2 and 4.4, the Purchaser shall have the right and
remedy to have such provisions specifically enforced by any court having equity
jurisdiction, it being


                                       54

   61

acknowledged and agreed that any such breach or threatened breach will cause
irreparable injury to the Purchaser and that money damages will not provide an
adequate remedy to the Purchaser.

            7.13 Public Announcements. No public announcement concerning the
transactions contemplated hereby may be made by either party without the consent
of the other except as may be required by law or the rules of any applicable
securities exchange.

            7.14 Entire Agreement; Termination of Certain Prior Agreements
Between Company and Sellers. This Agreement (including the Exhibits, Schedules,
documents and instruments referred to herein) constitutes the entire agreement
and understanding of the parties hereto and thereto with respect to the subject
matter hereof and thereof and supersedes all other prior agreements and
understandings, both written or oral, between such parties with respect to the
subject matter hereof and thereof. Without limitation to the foregoing, each
party hereto understands and agrees that all prior employment agreements between
the Company and any of the Sellers shall terminate effective as of the Closing.

   62

            IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be executed and delivered on their behalf as of the day and year first above
written.
