pursuant to this Section 6.3 (including fees of attorneys and other
professionals) shall be borne by the Party instituting the action, or, if the
Parties elect to cooperate in instituting and maintaining such action, such
costs and expenses shall be borne by the Parties in such proportions as they
may agree in writing. Each Party shall execute all necessary and proper
documents and take such actions as shall be appropriate to allow the other
Party to institute and prosecute such infringement actions (if such other Party
has the right to institute and prosecute such infringement actions pursuant to
this Section 6.3). Any award paid by Third Parties as a result of such an
infringement action (whether by way of settlement or otherwise) shall be paid
to the Party who instituted and maintained such action, or, if both Parties
instituted and maintained such action, such award shall be allocated among the
Parties in proportion to their respective contributions to the costs and
expenses incurred in such action, or as they may have otherwise agreed.
Notwithstanding the above, CADUS shall receive 25% of any such award by way of
settlement or otherwise after deducting legal and other reasonable expenses.

entitled, without prejudice to any of its other rights conferred on it by this
Agreement, in addition to any other remedies available to it by law or in
equity, to terminate this Agreement by giving written notice to take effect

terminate this Agreement shall not be affected in any way by its waiver or
failure to take action with respect to any previous default.

            7.4   Termination for Bankruptcy. CADUS may terminate this
Agreement if, at any time, OSI shall file in any court or agency pursuant to
any statute or regulation of any state or country, a petition in bankruptcy or
insolvency or for reorganization or for an arrangement or for the appointment
of a receiver or trustee of OSI or of its assets, or if OSI proposes a written
agreement of composition or extension of its debts, or if OSI shall be served
with an involuntary petition against it, filed in any insolvency proceeding,
and such petition shall not be dismissed within sixty (60) days after the
filing thereof, or if OSI shall propose or be a party to any dissolution or
liquidation, or if OSI shall make an assignment for the benefit of creditors.

8.    DISPUTE RESOLUTION

            8.1   Dispute Resolution. If one of the Parties hereto declares
that a dispute between the Parties has arisen related to this Agreement, such
dispute shall, in the first instance, be the subject of good faith negotiations
between the Parties to resolve such dispute. Should the negotiations not lead
to a settlement of the dispute within thirty (30) days of the date of the
meeting, the Parties shall refer the dispute to a mutually acceptable mediation
service to resolve the dispute. The mediation shall be attended by individuals
from within each Party who have decision-making authority with respect to the
matter in question. If the mediation does not lead to a settlement of the
dispute within thirty (30) days of the date of the meeting, then the Parties
shall submit the issue to arbitration before a panel of arbitrators under the
commercial rules of the American Arbitration Association.  Unless the Parties
otherwise agree, the arbitration will be held in New York, New York.  The panel
of arbitrators shall consist of three parties: one selected by each Party, as
well as a disinterested third party that the two arbitrators shall name. The
third arbitrator shall be a person who has had experience in the business of
biotechnology licensing. If a qualified person in this field cannot be found
and agreed upon, the two arbitrators shall use their own discretion and select
a third arbitrator with qualifications as they deem appropriate. The three
arbitrators shall be given full power to hear and finally determine and dispose
of all disputes between the parties that may arise from or that are related to
this Agreement. The arbitrator will make their ruling in writing no later than
thirty (30) days after the hearing. The decision of two of the three
arbitrators will be binding

                                       10
<PAGE>   11

on the Parties. No Party has a right to appeal the ruling, to any court or
otherwise. Judgment upon the decision rendered may be entered in any court
having jurisdiction or application may be made to such court of a judicial
acceptance of the award and an order of enforcement, as the case may be. Each
Party shall pay its own attorney's fees. All fees and expenses payable with
respect to the mediation and arbitration proceedings shall be shared by both
Parties during the course of the mediation and arbitration proceedings, but, in
the case of arbitration, shall be reimbursed in favor of the prevailing Party
after the arbitration ruling is rendered. Notwithstanding this Section 8.1,
CADUS shall have the right to seek injunctive relief pursuant to Section 11.12
hereof.

9.    INDEMNITY. INSURANCE AND REPRESENTATIONS

            9.1   Indemnity.  OSI agrees to indemnify, hold harmless and defend
CADUS, its directors, officers, employees and agents against any and all

industry. CADUS shall have the right to ascertain from time to time that such
coverage exists, such right to be exercised in a reasonable manner.

            9.3   Warranties and Representations.  Nothing in this Agreement
shall be deemed to be a representation or warranty by CADUS of the validity of
any of the CADUS Patents or the accuracy, safety, efficacy or usefulness for
any purpose of any technology licensed hereunder. CADUS shall have no
obligation, express or implied, to supervise, monitor, review or otherwise
assume responsibility for the production, manufacture, testing, marketing or
sale of any Product(s), and CADUS shall have no liability whatsoever to OSI or
any Third Parties for or on account of any injury, loss or damage, of any kind
or nature, sustained by, or any damage assessed or asserted against, or any

administrative proceeding after legal remedies for maintaining the subject
matter in confidence have been exhausted.

            10.2  Duration of Confidentiality Obligation.  OSI's obligations of
confidentiality shall continue during the term of this Agreement and for a
period of five years thereafter.

            11.8  Severability.  When possible, each provision of this
Agreement will be interpreted in such manner as to be effective and valid under
applicable law, 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 this Agreement, and the Parties shall negotiate in good faith to
modify this Agreement to preserve (to the extent possible) their original
intent.

with respect to the subject matter hereof including without limitation the

            11.12  Injunctive Relief.  OSI acknowledges that, in the event of
its breach or threatened breach of any of the provisions of this Agreement,

Section 11.12 shall not, however, be construed as a waiver of any of the rights
which CADUS may have for damages or otherwise.

            11.13  Counterparts.  This Agreement may be executed simultaneously
in any number of counterparts, any one of which need not contain the signature
of more than one Party but all such counterparts taken together shall
constitute one and the same agreement.

Agreement are for convenience only and shall be of no force or effect in

Gentlemen:

         Reference is made to the Certificate of Designation (the "Certificate")
creating the series of preferred stock of Symposium Corporation, a Delaware
corporation (the "Company"), designated as the Series A Preferred Stock, par
value $.10 per share (the "Series A Shares") and the Term Sheet (the "Term
Sheet") describing the terms upon which the Series A Shares were offered and
sold to Lancer Offshore Inc. and Capital Research, Ltd. (collectively, the
"Holders"). The Certificate and the Term Sheet are hereinafter collectively
referred to as the "Documents."

         The Documents provide that the if the Series A Shares are not redeemed
in full within 60 days following issuance (such 60th day being March 28, 2000):
(A) the price at which the Series A Shares are convertible into shares of the
Company's Common Stock will be reduced from $2.00 per share to $0.10 per share;
and (B) the Company will be required to issue to the holders of the Series A
Shares, an aggregate of 215,000 five year warrants per month (the "Warrants")
until the Series A Shares are redeemed in full, such Warrants to be issued on
the first day of each thirty day period, and to have an exercise price of $0.10
per share.

         The Company and the Holders hereby agree as follows:

         1. Notwithstanding any provision of the Documents to the contrary, the
reduction of the conversion price of the Series A Shares referred to in clause
(A) above and the requirement that the Company issue Warrants on a monthly basis
referred to in clause (B) above will not become effective if the Company redeems
the Series A Shares in full on or before April 12, 2000 (such date being the
75th day following issuance of the Series A Shares). If the Company fails to
redeem the Series A Shares in full on or prior to April 12, 2000, then the
reduction of the conversion price of the Series A Shares referred to in clause
(A) above and the

requirement that the Company issue Warrants on a monthly basis referred to in
clause (B) above will become effective as of April 13, 2000 and will remain
effective thereafter unless and until the Series A Shares are redeemed in full.

         2. The agreements of the Company and the Holders set forth in paragraph
1 will not abrogate or amend any other obligations of the Company set forth in
the Documents with respect to the Series A Shares (which other obligations shall
remain in full force and effect), including without limitation the obligation of
the Company to issue to the Holders an aggregate of 16,125 shares of Common
Stock per day for each day from March 1 through March 28, 2000; and to issue to
the Holders an aggregate of 26,875 shares of Common Stock per day for each day
after March 28, 2000, such obligations to continue in effect until the day on
which the Series A Shares are redeemed in full.

         3. The Holders will irrevocably consent, with respect to all shares of
the Common Stock owned beneficially or of record by the Holders, to the proposed
amendment (the "Amendment") to the Company's Amended and Restated of
Incorporation increasing the number of authorized shares of the Common Stock
from 25,000,000 shares to 75,000,000 shares (and thereby increasing the total
number of authorized shares of capital stock of the Company from 35,000,000 to
85,000,000 shares).

         4. In consideration of the agreements of the Holders set forth herein,
the Company hereby agrees to issue to the Lancer Offshore Inc. an aggregate of
250,000 shares of Common Stock and to Capital Research, Ltd. an aggregate of
25,000 shares of Common Stock (such 250,000 shares and 25,000 shares being
collectively referred to as the "Additional Shares"), such issuances to become
effective on the date the Amendment is filed with the Secretary of State of
Delaware.

         5. Each of the Holders each hereby severally represents to the Company,
on behalf of itself, that each of such Holder is (and on the date of issuance of
such Additional Shares will be) an "accredited investor" within the meaning of
Regulation D, as promulgated by the Securities and Exchange Commission pursuant
to the Securities Act of 1933, as amended (the "Act"), and has such knowledge
and experience in financial and business matters that it is capable of
evaluating the merits and risks of an investment in the Additional Shares; that
such Holder is acquiring the Additional Shares to be issued to such Holder for
investment and without a view to the sale, assignment, transfer or other
distribution thereof; the Additional Shares may not be offered for sale, sold or
otherwise transferred except pursuant to an effective registration statement
under the Act and in compliance with the applicable securities laws of any state
or other jurisdiction, or pursuant to an opinion of counsel satisfactory to the
Company that such registration is not required and such compliance has been
obtained. The Company may affix an appropriate legend to any certificate(s)
representing the Additional Shares to reflect the foregoing.

         6. This letter will be governed by the laws of the State of New York
applicable to contracts made and to be performed entirely within such State. Any
claims or disputes relating in any way to this Agreement shall be submitted to
the New York State courts or the United States District Court for the Southern
