            3.3.3 ROYALTY OFFSETS In the event that royalty payments are owed by
Spectrum to Third Parties with respect to licenses necessary to use, develop,
manufacture, import or sell a Product, the royalties owed to Dr. Bases under
Section 3.3.1 shall be reduced by *** of the amount of the royalty payments
actually paid by Spectrum to such Third Parties provided that such reductions
shall not reduce the royalty paid to Dr. Bases in such country below *** Percent
(***%)

            3.3.4 *** ROYALTY PAYMENTS Royalties owed to Dr. Bases pursuant to
this Article 3 shall be payable by Spectrum within *** after the end of each ***
(i.e., *** after ***) based upon the Net Sales of each Product during such ***.
Any underpayment or overpayment of the *** royalty payments shall be reconciled
and added or deducted to the royalty payment due in the *** in which such
underpayment or overpayment is discovered. In the case of sales outside the
United States, the rate of exchange to be used in computing the amount of
currency equivalent in U. S. Dollars due Dr. Bases shall be made at the rate of
exchange utilized by Spectrum in its worldwide accounting system under GAAP.

            3.3.5 REPORTS Spectrum shall furnish to Dr. Bases at the same time
as each royalty payment is made by Spectrum, a written report of Net Sales of
the Products on a Product by Product and country by country basis and the
royalty due and payable thereon, for the *** period upon which the royalty
payment is based. Net Sales made in currencies other than U.S. Dollars will be
translated into U.S. Dollars as provided in Section 3.3.4 and added to Net Sales
made in U.S. Dollars for purposes of determining aggregate Net Sales and the
royalties due to Dr. Bases.

      3.4 PAYMENTS With the exception of the initial *** payment set forth in
Section 3.1, which shall be paid to Dr. Bases, all cash payments due to Dr.
Bases under this Agreement shall be paid to the Foundation (unless otherwise
directed in writing by Dr. Bases) in U. S. Dollars by check or bank wire
transfer in immediately available funds to such bank account in the United
States designated in writing by Dr. Bases from time to time.

      3.5 RECORDS Spectrum shall keep full, complete and proper records and
accounts of all sales of Products by Spectrum, its Affiliates and sublicensees
in accordance with GAAP, in sufficient detail and in the currencies in which the
sale was made to enable the royalties payable on each Product to be determined.
All such records, statements, reports and accounts referred to in this Section
3.5 shall be retained for a period of three (3) years after the end of the
period to which they apply.

      3.6 INCOME TAX WITHHOLDING If laws, rules or regulations require
withholding of income taxes or other rates imposed upon payments set forth in
this Article 3, Spectrum may make such withholding payments as required and
subtract such withholding payments from the payments set forth in

this Article 3. Spectrum shall submit appropriate proof of payment of the
withholding rates to Dr. Bases within a reasonable period of time. Spectrum
shall 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 circumstances providing
the documentation required under such treaty or agreement to claim benefits
thereunder.

      3.7   AUDIT If Dr. Bases disagrees with a royalty report provided by
Spectrum, with reasonable justification for such disagreement, Dr. Bases, at his
own expense, shall have the right, upon reasonable prior notice during regular
business hours, to meet with Spectrum's independent auditor to inspect and
discuss the books and accounts of Spectrum or its Affiliates, related to the
payment and calculation of royalties arising under this Agreement. After this
inspection, if Dr. Bases still disagrees with the report provided by Spectrum,
with reasonable justification for such disagreement, Dr. Bases, at his own
expense, shall have the right, upon reasonable prior notice during regular
business hours, to appoint independent auditors reasonably acceptable to
Spectrum and have them during normal business hours, inspect and copy the books
and accounts of Spectrum or its Affiliates, related to the payment and
calculation of royalties arising under this Agreement. Spectrum shall cooperate
and cause Spectrum's Affiliates, to cooperate with such auditors. The auditors
performing the audit shall disclose to Dr. Bases only information relating to
the accuracy of records kept and the payments made, and shall be under a duty to
keep confidential any other information obtained from such records. Spectrum
shall audit the books and accounts of its sublicensees, if any, using its
independent auditor or a comparable reputable auditor. Spectrum shall share the
results of its audit with Dr. Bases.

            3.7.1 If any such audit establishes that Spectrum has underpaid or
overpaid the amount due, Spectrum shall promptly pay any remaining amounts due
as established by such audit or Dr. Bases shall promptly refund any over
payment. If the underpayment is more than *** percent (***%) of the aggregate
Net Sales for all countries during any calendar year, Spectrum shall reimburse
Dr. Bases for his out-of-pocket expense of such audit, together with interest at
the rate specified in Section 3.8 below for late payments on any such overdue
payment from the date due until paid.

      3.8   LATE PAYMENTS Any payments due Dr. Bases under this Agreement that
are not paid on the due date shall accrue interest at the lower of the rate of
*** percent (***%) per annum, or the maximum rate allowed by law, from the due
date until paid in full.

4.    OWNERSHIP AND PATENT MATTERS.

      4.1 OWNERSHIP As between the parties, all Technology shall be owned by Dr.
Bases. Improvements that are made to Technology by an employee, agent or
consultant of Spectrum, solely or jointly with a Third Party, shall be owned by
Spectrum. Improvements that are made jointly by employees, agents or consultants
of Spectrum and Dr. Bases and his employees, agents or consultants ("JOINT
INVENTIONS") shall be jointly owned by Spectrum and Dr. Bases and treated as
joint inventions under U.S. laws applicable to joint inventions. Dr. Bases
shall, and hereby does, grant Spectrum the exclusive and unrestricted right
(even as to Dr. Bases, subject to Section 2.4) in the Licensed Field to make,
have made, use, sell, have sold, import, export and license Dr. Bases' interest
in all Joint Inventions. Notwithstanding anything to the contrary, Dr. Bases
agrees to assign and agrees to have any employees, agents, and/or consultants
paid by Dr. Bases assign to Spectrum all right, title and interest to
Improvements that may accrue to Dr. Bases and/or any of his employees, agents
and/or consultants under clinical study agreements that Spectrum and Dr. Bases
and/or his employees, agents and/or consultants are a party to related to the
research and/or development of a Product. For the avoidance of doubt, Dr. Bases
does not have the authority to bind, and does not agree to bind, any third party
institution conducting a clinical study or any person subject to obligations
owed by such a person to such an institution and Dr. Bases' agreement to assign
rights in accordance with this Article 4, is subject to any pre-existing
obligations that Dr. Bases may have to a third party institution. Dr. Bases
hereby grants to Spectrum the exclusive and unrestricted right (even as to Dr.
Bases, subject to Section 2.4) in the Licensed Field to make, have made, use,
sell, have sold, import, export and license all Improvements made solely by Dr.
Bases, his employees or consultants in accordance with the provisions of the
present Agreement, including but not limited to the Royalty provisions and
shall, and hereby does, after Spectrum's royalty obligations under Section 3.3

Dr. Bases or due to the insolvency of Dr. Bases pursuant to Article 10, grant
Spectrum a perpetual, royalty-free license to use all Improvements owned by Dr.
Bases and all information, know-how and other data pertaining to all
Improvements and the Joint Inventions. Spectrum shall own any trademarks
associated with the Products.

            4.2.1 PATENT PROSECUTION AND MAINTENANCE Spectrum, at its own
expense, shall direct and control the preparation, filing, prosecution and
maintenance of all United States and foreign Patents within the Patent Rights
and all Joint Patents, including any interferences and foreign oppositions.

            4.2.2 PARTICIPATION AND ASSISTANCE Spectrum shall consult with Dr.
Bases with regard to the preparation, filing, prosecution and/or maintenance of
the Patents within the Patent Rights and any Joint Patents. Notwithstanding the
preceding sentence, however, Spectrum shall in all events have final
decision-making authority as relates to the preparation, filing, prosecution
and/or maintenance of the

                                       10


Patents within the Patent Rights any Joint Patents and the scope of claims
contained therein. Dr. Bases shall cooperate fully with Spectrum, at Spectrum's
request, in all matters relating to the preparation, filing, prosecution and/or
maintenance of the Patents within the Patent Rights and any Joint Patents,
including without limitation, signing any necessary or appropriate documents,
providing written and testimonial evidence, and doing such other acts as
Spectrum may reasonably require.

            4.2.3 PATENT ABANDONMENT In the event Spectrum elects not to
prosecute or to discontinue or abandon the prosecution and/or maintenance of any
patent or patent application within the Patent Rights, any such patent or patent
application shall at that time be excluded from the definition of Patent Rights
and from the scope of the licenses granted under this Agreement. Spectrum shall
give Dr. Bases at least *** prior written notice of its election to discontinue
or abandon any such patent or patent application within the Patent Rights during
which time Dr. Bases may elect, in his sole discretion, to prosecute, file,
continue and maintain such patent or patent application at his sole cost and
expense and for his sole benefit by delivery of written notice to Spectrum. If
Dr. Bases does not notify Spectrum in writing during such *** period that it is
exercising such rights, the patent or patent application shall be deemed
abandoned and neither Dr. Bases nor Spectrum shall have any further
responsibility for any such abandoned patent applications or patents. However,
if Dr. Bases does not elect to prosecute, file, continue and maintain such
patent or patent application, Spectrum may later elect to continue to prosecute
and maintain such patent or patent application, in which case, the patent or
patent application shall remain within the Patent Rights and licenses hereunder.

            4.2.4 EXECUTION OF DOCUMENTS Each Party shall promptly execute or
have executed by its employees, agents and consultants all documents necessary
to vest ownership of inventions and related intellectual property rights
relating to Joint Patents in Dr. Bases and Spectrum and to enable Spectrum to
file, prosecute and maintain the Patents within the Patent Rights and Joint
Patents. If Spectrum is unable, after reasonable effort, to secure the signature
of Dr. Bases or any employee, agent or independent contractor of Dr. Bases on
any document needed to apply for, prosecute or defend any patent or other
intellectual property right or protection relating to the Patent Rights or the
Joint Patents, Dr. Bases hereby designates and appoints Spectrum and its duly
authorized officers and agents as its agent and attorney in fact to execute,
verify and file applications, and to do all other lawfully permitted acts
necessary to protect Spectrum's rights in Joint Patents and to enable Spectrum
to file, prosecute and maintain Patent Rights and Joint Patents with the same
legal force and effect as if executed by Dr. Bases.

Section, Dr. Bases shall have the right, in his sole discretion, to respond to

      7.1 BY DR. BASES

                  (a) Dr. Bases hereby represents and warrants that as of the
Effective Date: (A) he has all necessary right and authority to execute, deliver
and perform all of his obligations under this Agreement; (B) he has the right to
grant the licenses and other rights granted herein; (C) he has not previously
granted any right, license or interest in or to the Technology, or any portion
thereof, inconsistent with the rights granted to Spectrum herein; and (D) to the
best of his knowledge, there are no material adverse proceedings, claims or
actions pending or threatened relating to the Technology which would materially
interfere with Dr. Bases' performance of his obligations or power to make the
grants and covenants hereunder, or Spectrum's unfettered use of the Technology.

                  (b) The Technology is free and clear of any and all
encumbrances, covenants, conditions and restrictions or, other adverse claims or
interests of any kind or nature, and Dr. Bases has not received any oral or
written notice or claim challenging his complete and exclusive rights to the
Technology or suggesting that any other person has any claim of legal or
beneficial ownership with respect thereto, and there is no agreement, decree,
arbitral award or other provision or contingency which obligates Dr. Bases to
grant licenses in the Technology.

                  (c) To Dr. Bases' knowledge, he owns or possesses sufficient
rights to use all of the Technology necessary to develop, make, have made, use,
sell, offer for sale, have sold, import and export and commercialize Products in
the Licensed Field in the Territory.

                  (d) No litigation is now pending and no notice or other claim
has been received by Dr. Bases, (A) alleging that Dr. Bases has engaged in any
activity or conduct that infringes upon, violates or constitutes the
unauthorized use of any Patents of any Third Party, or (B) challenging the
ownership, use, validity or enforceability of any of the Patents within the
Patents Rights.

                  (e) Dr. Bases confirms that he has been given sufficient
access to information regarding Spectrum in connection with his decision to

answers from, persons acting on behalf of the Spectrum concerning its respective
financial affairs, prospects and condition.

                  (f) Dr. Bases represents and warrants that, by reason of his
business or financial expertise, he has the capacity to protect his own
interests in connection with his acquisition of the Shares and that he is an
"accredited investor" as defined in Rule 501 of Regulation D of the Securities
Act of 1933, as amended (the "Securities Act").

                  (g) Dr. Bases represents, warrants and covenants that he shall
acquire the Shares for his own account and not for the account or on behalf of

the Securities and Exchange Commission.

                  (i) Dr. Bases acknowledges that (i) he must and shall bear the
economic risk of holding the Shares for an indefinite period of time because at

Securities Act or any other securities law and, therefore, cannot be sold unless
they are subsequently registered under applicable national, federal, provincial
and state securities laws or an exemption from such registration is available;
(ii) the Shares may not be resold or transferred on the official stock transfer
records of Spectrum without furnishing to Spectrum an opinion of counsel
reasonably acceptable to Spectrum that such sale or transfer of the shares will
not violate the registration provisions of applicable national, federal,
provincial and state securities laws; and (iii) certificates representing the
shares shall have endorsed on them a restrictive legend to this effect.

                  (j) Dr. Bases confirms that he is not purchasing the Shares as
a result of or subsequent to any advertisement, article, notice or other
communication regarding the Shares published in any newspaper, magazine or
similar media or broadcast over television or radio or presented at any seminar
or any other general solicitation or general advertisement.

                  (k) Dr. Bases acknowledges that Spectrum is relying on the
representations, warranties, covenants and acknowledgments in this Section 7.1
to ensure that the Shares that may be issued under the terms of this Agreement
can be issued in reliance on exemptions from registration requirements under
United States federal and state securities laws.

good standing under the laws of the State of Delaware; (B) it has the full
right, authority and power to enter into this Agreement and to perform its
obligations hereunder; (C) the execution, delivery and performance of this
Agreement have been duly authorized by all necessary corporate action on the
part of Spectrum; and (D) to the best of its knowledge there are no material
adverse proceedings, claims or actions pending or threatened against it which
would materially interfere with the performance of its obligations hereunder.
Spectrum represents, warrants and covenants that the Shares that may be issued
to Dr. Bases under Section 3.2 of this Agreement will, upon issuance, be duly
authorized, validly issued, fully paid and nonassessable.

in or to the Technology, or any portion thereof, inconsistent with the rights
granted to Spectrum herein. Without the other Party's prior written consent,
neither Party shall enter into any agreement that creates additional obligations

9.    CONFIDENTIALITY AND PUBLICATION.

      9.1 TREATMENT OF CONFIDENTIAL INFORMATION The Parties agree that during
the term of this Agreement, and for a period of seven (7) years after this
Agreement terminates or expires, a Party receiving Confidential Information of
the other Party will (i) maintain in confidence such Confidential Information to
the same extent such Party maintains the confidentiality of its own Confidential
Information, (ii) not disclose such Confidential Information to any Third Party
without the prior written consent of the disclosing Party and (iii) not use such
Confidential Information for any purpose other than the exercise of a Party's
rights or performance of a Party's obligations under this Agreement; provided
however, that the provisions of this Section 9.1 shall not prevent a Party from
disclosing Confidential Information if such disclosure:

                  (a) is made to its employees, directors, accountants,
attorneys, contractors or consultants who reasonably require such disclosure on
a need to know basis and who are bound to it by obligations of confidentiality
and non-use no less stringent than the obligations between Spectrum and Dr.
Bases hereunder;

                  (b) is made to collaborators for the purpose of performing the
obligations or exercising the rights of a Party hereunder and who are bound to
that Party by obligations of confidentiality and non-use no less stringent than
the obligations between Spectrum and Dr. Bases hereunder;

                  (c) is in response to a valid order of an United States court
or otherwise required by law or regulation, provided however that receiving
Party shall first have given notice to the disclosing Party and shall have made
a reasonable effort to obtain a protective order by: (i) seeking protection of
Confidential Information not relevant to the court's inquiry from a general
disclosure (e.g., without limitation, requesting limited and in-camera review by
such court and/or seeking that such information be treated under seal); (ii)
seeking to redact any Confidential Information; and (iii) in any event requiring
that, to the extent ordered to be disclosed, that such disclosure of
Confidential Information be used only for the purposes for which the order was
issued; or

                                       18


                  (d) is necessary to: (i) file or prosecute Patents in

Products in accordance with this Agreement; (iii) prosecute or defend
litigation; (iv) make required governmental securities filings and other such
similar and required disclosures by law, subject to appropriate redactions and
requests for confidential treatment as permitted by law; (v) make disclosures
required by the principal stock exchange on which the Party's stock is traded,
subject to appropriate redactions and requests for confidential treatment as
permitted by law and the rules of such exchange; (vi) conduct pre-clinical or
clinical trials of Products in accordance with this Agreement, provided any
Affiliates or Third Parties conducting pre-clinical trials agree to be bound by
terms of confidentiality and non-use at least equivalent in scope to those set
forth in this Section 9.1 and any Affiliates or Third Parties conducting
clinical trials agree to be bound by terms of confidentiality and non-use that
are customarily obtained in connection with such clinical trials; or (viii)
enable Affiliates or bona fide potential or actual sublicensees to evaluate
and/or exercise their rights under a sublicense that would be or has been issued
in accordance with this Agreement, provided such Affiliates and Third Parties
agree to be bound by similar terms of confidentiality and non-use at least
equivalent in scope to those set forth in this Section 9.1.

      9.2   PUBLIC STATEMENTS.

            9.2.1 PUBLICATIONS Dr. Bases or Spectrum, as the case may be, may
publish or present information derived from the performance of this Agreement,
provided that: the publishing Party first provides the non-publishing Party with
a copy of the proposed publication or presentation for comment and input at
least forty-five (45) days prior to any submission for publication or
presentation and if any such information was derived from the non-publishing
Party's efforts under this Agreement, the non-publishing Party shall have the
right to require the publishing Party to redact such information from the
proposed publication. In addition, at the non-publishing Party's request, the
publishing party will further delay the presentation or publication for an
additional forty-five (45) days so as to allow the non-publishing party time to
file for patent protection or other intellectual property protection. If a
publication by Spectrum results from work relating to the Technology, Spectrum
agrees to acknowledge Dr. Bases and give credit to Dr. Bases' scientists, as
scientifically appropriate, based on any contribution they may have made to the
work. Likewise, if a publication by Dr. Bases results from work performed by
Spectrum, Dr. Bases agrees to acknowledge Spectrum and give credit to Spectrum'
scientists, as scientifically appropriate, based on any contribution they may
have made to the work.

            9.2.2 OTHER PUBLIC STATEMENTS Except as provided in Section 9.2.1,
or as otherwise required by law or the rules of the principal stock exchange on
which the Party's stock is traded, no Party shall originate any public
statement, news release or other written public announcement, whether in the
public press, stockholders' reports, or otherwise, relating to this Agreement or
to any sublicense hereunder, or to the performance hereunder or any such
agreements, or use a Party's name for any

                                       19


purpose, including, without limitation, in connection with the advertising or
sale of Products, without the prior written approval of the other Party, such
consent not to be unreasonably withheld. The Parties each agree to respond to
each such request within five (5) business days of receipt of a request (unless
a shorter period of time is necessary to comply with law). Notwithstanding
anything to the contrary in this Agreement, each party shall be permitted to
publicly disclose (i) the existence of this Agreement, (ii) that Dr. Bases and
Spectrum are the parties to this Agreement, and (iii) the Technology covered by
this Agreement. In the case of unintentional public disclosure concerning this
Agreement, any Product or any other subject matter hereof, the disclosing Party
shall promptly inform the other Party of such disclosure and the other Party
shall be entitled to make a public announcement regarding the subject matter of
the disclosure. The other Party shall notify the disclosing Party of their
intention to make such an announcement. Following a Party's consent to or
approval of the public announcement of any information pursuant to this Section
9.2.2, both Parties shall be entitled to make subsequent public announcements of
such information without renewed compliance with this Section 9.2.2, unless the
scope and/or duration of such consent or approval is expressly limited. Upon
conclusion of this Agreement, the Parties will publish a press release on their
future cooperation.

10.   TERM, DEFAULT AND TERMINATION.

      10.1 TERM OF AGREEMENT The term of this Agreement shall commence on the
Effective Date and, unless terminated early in accordance with the provisions of
this Agreement, shall continue on a Product-by-Product and country-by-country
basis until the expiration of the obligation to pay royalties under Section 3.3
above applicable to such Product in such country (the "TERM"). This Agreement
shall expire in its entirety after the date that Spectrum no longer owes any
royalties to Dr. Bases under Section 3.3.

      10.2 UNILATERAL TERMINATION - SPECTRUM Spectrum shall have the unilateral
right to terminate this Agreement, in its entirety or on a Product-by-Product or
country-by-country basis, at any time for any reason upon prior written notice
to Dr. Bases given at least *** prior to the desired date of termination.

      10.3  DEFAULT.

            10.3.1 The following event shall constitute an "EVENT OF DEFAULT"
hereunder: a material breach of a material provision of this Agreement by a
Party, and the failure of the Party in breach to cure such material breach
within *** after receipt of notice from the other Party specifying in reasonable
detail the nature of such breach. For purposes of this Agreement, it is not a
"material breach" of this Agreement by Spectrum if the development of a Product
is delayed due to the following: (i) reasonable scientific, medical or technical
reasons; (ii) circumstances that are beyond the control of Spectrum; or (iii)
the fault of Dr. Bases.

            10.3.2 Upon the occurrence of any Event of Default by a Party, the
non-defaulting Party may deliver to the defaulting Party written notice of
intent to terminate specifying in reasonable detail the nature of such breach,
such termination to be effective *** after the date set forth in such notice.
Such termination rights shall be in addition to and not in substitution for any
other remedies that may be available to the non-defaulting Party. Termination
pursuant to this Section 10.3.2 shall not be treated as an election of remedies
and shall not relieve the defaulting Party from liability and damages to the
other Party for breach of this Agreement. Waiver by either Party of a single
breach or a succession of breaches shall not deprive such Party of any right to
terminate this Agreement arising by reason of any subsequent breach.

            10.4 INSOLVENCY In addition to the termination rights provided for
in this Section, each Party shall have the right to terminate this Agreement,
immediately by giving written notice of termination to the other Party, if the
other Party files a voluntary petition, or if an involuntary petition is granted
in respect of the other Party and appeal proceedings are not commenced within a
period of fifteen (15) days from the date of such petition under the bankruptcy
provisions of applicable law, or the other Party is declared insolvent,
undergoes voluntary or involuntary dissolution, or makes an assignment for the
benefit of its creditors, or fails or is unable to pay its debts as they come
due, or suffers the appointment of a receiver or trustee over all, or
substantially all, of its assets or properties. All rights and licenses granted
under or pursuant to this Agreement by Dr. Bases are, for the purposes of
Section 365(n) of the U.S. Bankruptcy Code, licenses of rights to "intellectual
property" as defined under Section 101 of the U.S. Bankruptcy Code. The Parties
agree that Spectrum shall retain and may fully exercise all of its rights and
elections under the U.S. Bankruptcy Code.

      10.5  EFFECTS OF EXPIRATION OR TERMINATION

                  (a) RIGHTS UPON EXPIRATION. Following the expiration of the
term of this Agreement under Section 10.1, excluding any early termination prior
to expiration, Spectrum shall have and retain a perpetual and fully paid up
license under the applicable Product Licenses. Notwithstanding the foregoing,
Spectrum shall retain all rights and interest in all materials, inventions,
discoveries and know-how (whether or not patentable or patented) solely
generated by Spectrum in the course of performing research and development
activities under the licenses granted in this Agreement. Other than rights
intended to survive expiration, or as otherwise provided under Section 10.5(e),
neither Party shall have any further rights or obligations upon the expiration
of this Agreement.

                  (b) RIGHTS UPON TERMINATION BY DR. BASES UNDER SECTIONS 10.3
OR 10.4 OR BY SPECTRUM UNDER SECTION 10.2. Upon any termination of this
Agreement by Dr. Bases under Section 10.3 or 10.4 or by Spectrum under Section
10.2, (i) all rights and licenses granted by Dr. Bases to Spectrum shall
terminate and revert to Dr. Bases and (ii) Spectrum shall return to Dr. Bases
or, at Dr. Bases' option, destroy the Materials. The foregoing provisions shall
also apply to the partial termination of this Agreement by Spectrum on a
Product-by-Product and/or country-by-country basis in accordance with Section
10.2, provided, however, that in such event: (1) only those rights that solely
pertain to the Product and/or country being terminated would revert back to Dr.
Bases; (2) only those Materials that solely pertain to the Product and/or
country being terminated would be returned or destroyed by Spectrum. In addition
Spectrum shall at no cost to Dr. Bases transfer to Dr. Bases the benefit of all
research and development work it has performed or has had performed on Products.
At the same time, Spectrum shall provide to Dr. Bases at no cost to Dr. Bases
all CMC data, preclinical testing and stability data and results and clinical
trial data and results relating to the development of Products and a technology
transfer package for all processes, formulations, and protocols for the
manufacture of APIs for Products and for finished Products. If Spectrum has
licensed any technology from Third Parties relating to the Technology or any
Product, Spectrum shall use commercially reasonable efforts to transfer such
rights to Dr. Bases at no cost to Dr. Bases. Notwithstanding the foregoing,
Spectrum shall retain its right, title and interest under Section 4.1 in any
Improvements made solely by Spectrum and in any Joint Inventions.

                  (c) Rights Upon termination by Spectrum under Sections 10.3 or
10.4. Upon any termination of this Agreement by Spectrum under Sections 10.3 or
10.4, the license rights granted by Dr. Bases to Spectrum contained in this
Agreement shall continue in full force and effect, however, Spectrum's
obligations under this Agreement shall terminate. Notwithstanding the foregoing,
Dr. Bases shall retain his rights under Section 2.4 and his right, title and
interest under Section 4.1 in any Joint Inventions. For the avoidance of doubt,
in the event of such a termination by Spectrum under Section 10.3 or 10.4, the
retention by Dr. Bases of his rights under Section 2.4 shall only include the
right to use the Know-How for his own research and other non-commercial purposes
and Dr. Bases may not

                                       22


use the Know-How or the results of his research for any commercial purposes and
may not allow others to use it or any results from his research for any
commercial purposes.

                  (d) PAYMENTS. Not later than *** after the expiration or
termination date of this Agreement, each Party shall pay to the other Party any
amounts that are then due and payable, including but not limited to any final
period royalty report and payment. Notwithstanding anything in this Agreement to
the contrary, Spectrum shall not be required to pay any remaining monthly
installments yet to be paid pursuant to Section 3.1 above, if this Agreement is
terminated prior to the payments of all installments pursuant to Section 3.1.

                  (e) ACCRUED RIGHTS; SURVIVING OBLIGATIONS. Termination or
expiration of this Agreement for any reason shall be without prejudice to any
rights which shall have accrued to the benefit of either Party prior to such
termination or expiration, and shall not relieve either Party from its
obligations which are expressly indicated to survive expiration or termination
of this Agreement, including, without limitation, those under Articles 6, 9, 11
and 12 and Sections 3.5 through 3.8, 4.1 through 4.3, 10.5 and 10.6 shall
survive any expiration or termination of this Agreement.

      10.6 WORK-IN-PROGRESS Notwithstanding anything in this Agreement to the
contrary, upon any such early termination of the license granted hereunder in
accordance with this Agreement, Spectrum shall be entitled to finish any
work-in-progress and to sell any completed inventory of a Product which remain
on hand as of the date of the termination, so long as Spectrum pays to Dr. Bases
the royalties applicable to said subsequent sales in accordance with the terms
and conditions as set forth in this Agreement, provided that no such sales shall
be permitted after the expiration of *** after the date of termination.

out of or relating to this Agreement, including, without limitation, any action
or claim based on tort, contract or statute, or concerning the interpretation,
effect, termination, validity, performance and/or breach of this Agreement

arbitrator will be selected by Dr. Bases, one (1) arbitrator will be selected by
Spectrum, and the third arbitrator will be selected by mutual agreement of the
two (2) arbitrators selected by the Parties, provided that if a Party fails to
select an arbitrator within thirty (30) days of the request for arbitration, the
arbitrator that was to be selected by such Party shall be appointed in
accordance with the rules of the AAA. During the period prior to the hearing,
each Party shall have the right to conduct up to two (2) depositions and to
submit up to twenty (20) document requests to the other Party. The arbitrators
may proceed to an award, notwithstanding the failure of either Party to
participate in the proceedings. The arbitrators shall, within forty-five (45)
calendar days after the conclusion of the arbitration hearing, issue a written
award and statement of decision describing the essential findings and
conclusions on which the award is based, including the calculation of any
damages awarded. The arbitrators shall be authorized to award compensatory
damages, but shall NOT be authorized to (i) award non-economic or punitive
damages (except to the extent expressly permitted by this Agreement), or (ii)

limitation, an injunction or order for specific performance. The award of the
arbitrators shall be the sole and exclusive remedy of the Parties. Judgment on
the award rendered by the arbitrators may be enforced in any court having
competent jurisdiction thereof, subject only to revocation on grounds of fraud
or clear bias on the part of the arbitrators. Notwithstanding anything contained
in this Section 11.1 to the contrary, each Party shall have the right to
institute judicial proceedings against the other Party or anyone acting by,
through or under such other Party, in order to enforce the instituting Party's
rights hereunder through specific performance, injunction or similar equitable
relief.

      11.2 ADMINISTRATION Each Party shall bear its own attorneys' fees, costs,
and disbursements arising out of the arbitration, and shall pay an equal share
of the fees and costs of the arbitrators; provided, however, that the
arbitrators shall be authorized to determine whether a Party is the prevailing
party, and if so, to award to that prevailing party reimbursement for its
reasonable attorneys' fees, costs and disbursements (including, for example,
expert witness fees and expenses, photocopy charges and travel expenses), and/or
the fees and costs of the arbitrators. Absent the filing of an application to
correct or vacate the arbitration award (if permitted by AAA rules), each Party
shall fully perform and satisfy the arbitration award within fifteen (15) days
of the service of the award.

      11.3 WAIVERS By agreeing to the binding arbitration provision in Section
11.1, the Parties understand that they are waiving certain rights and
protections which may otherwise be available if a Dispute between the Parties
were determined by litigation in court, including, without limitation, the right
to seek or obtain certain types of damages precluded by this provision, the
right to a jury trial, certain rights of appeal, and a right to invoke formal
rules of procedure and evidence.

controversy or claim that concerns (A) the validity, enforceability or
infringement of a Patent, trademark or copyright; or (B) any antitrust,
anti-monopoly or competition law or regulation, whether or not statutory. All
