within the GTX Patent Rights in such country; and (b) for which Orion has both a
license or other right to develop and commercialize such products and has
commenced, within five (5) years after the Amendment Date, a Phase I clinical
trial for such product anywhere in the world for a primary indication falling
within the Prostate Cancer Field (a product fulfilling (a) and (b), hereinafter
referred to as "Additional Product"). If Orion decides to offer to any Third
Party the opportunity to participate in the development or commercialization of
such Additional Product, or if Orion commences Phase I clinical trials for such
Additional Product, it shall so notify GTX in writing. [ * ] after GTX's receipt
of such notice from Orion regarding commercially

reasonable terms and conditions for obtaining rights in and to such Additional
Product, GTX shall notify Orion in writing if it wishes to enter into
negotiations with respect to such Additional Product. Should GTX elect to
exercise such right, the Parties agree to negotiate in good faith the
commercially reasonable terms and conditions for a letter of intent to be
completed [ * ] of receipt by Orion of such notification from GTX. Any deadlines
may be extended by mutual written agreement. Should GTX fail to provide written
notification to Orion by the end of [ * ], or GTX notifies Orion that it does
not wish to enter into negotiations; or the Parties, despite conducting good
faith negotiations, are unable to finalize the commercial terms of the letter of
intent [ * ], GTX shall have no further rights in the SERM, and Orion shall be
free to contract with a Third Party concerning same or itself further pursue the
development, registration, promotion, marketing, sales and distribution of such
Additional Product.

             2.1.6 GTX RIGHTS TO NEGOTIATE FOR RIGHTS IN THE ORION FIELD IN THE
ORION TERRITORY. With respect to the development and commercialization of
Products in the Orion Field in the Orion Territory, GTX shall have the following
rights:

                   (A) As of the Restatement Date, Orion has Third Party
licensees that have rights to develop and/or commercialize the Product in the
Orion Field and in the Orion Territory. If any such sublicense terminates at any
time during the Term after the Restatement Date, and if Orion desires to seek
another Third Party sublicensee under such rights, then Orion shall so notify
GTX and GTX shall have a right to negotiate with Orion the terms under which GTX
may obtain such rights to such Product in the Orion Field and in the Orion
Territory, on the following basis:

                   (B) If GTX is interested in negotiating with Orion for such
rights to Product in the Orion Field and in the Orion Territory, it shall notify
Orion thereof in writing within thirty (30) days of receiving Orion's notice.
The Parties shall negotiate in good faith for a period of ninety (90) days after
Orion receives GTX's notice of interest on the terms of an agreement governing
such rights and during said period Orion shall not grant such rights to any
Third Party. If the Parties fail within such ninety (90) day period to execute
such an agreement, then Orion shall thereafter be free to contract with any
Third Party with respect to the rights in question.

         2.2 NO IMPLIED LICENSES. Any rights not expressly granted by either
Party to the other Party in this Agreement are expressly reserved by the Party
owning or controlling such rights and, accordingly, no licenses other than those
specified herein shall be deemed granted by this Agreement by implication,
estoppel or otherwise.

         2.3 UNITED STATES GOVERNMENT RIGHTS. In the event it is determined that
any GTX Patent Rights were developed with the support of the United States
Government or any agency thereof (the "Government"), the Government will retain
rights in the GTX Patent Rights as set forth in Title 35 U.S.C. Section 200 et
seq. All rights herein granted to GTX are subject to any such rights held by the
Government and further subject to any restrictions or obligations that may be
imposed by the Government pursuant to such rights, at such time that it is
determined.

         2.4 ORION'S RIGHT OF FIRST NEGOTIATION.

                                       10.


             2.4.1 Whereas Orion has considerable knowledge and experience in
the marketing, sales and distribution of pharmaceutical products in, inter alia,
Scandinavia (which term shall for purpose of this Section 2.4 comprise the
countries of Denmark, Finland, Norway and Sweden), GTX undertakes to regard
Orion as its preferential partner for the marketing, sales and distribution of
the Product in Scandinavia for use in the Field (other than in the Orion Field
in the Orion Territory), subject to this Section 2.4.1. Consequently, GTX
grants, and shall cause its Affiliates and Unaffiliated Sublicensees who receive
a sublicense under the license granted to GTX pursuant to Section 2.1.1 in
Scandinavia to grant, to Orion a right of first negotiation to negotiate in good
faith an agreement(s) under commercially reasonable terms and conditions
regarding the marketing, sales and/or distribution by Orion of the Product in
Scandinavia for use in the Field (other than in the Orion Field in the Orion
Territory), with the express understanding that such commercially reasonable
terms and conditions shall not comprise an obligation to develop and register
the Product for use in the Field in any country of Scandinavia.

             2.4.2 Within thirty (30) days after Orion's receipt of a first
written offer from GTX regarding commercially reasonable terms and conditions
governing such rights, Orion shall notify GTX in writing if it wishes to
negotiate the terms and conditions under which Orion could obtain the rights
contemplated in this Section 2.4. Should Orion so exercise such right, the
Parties shall negotiate exclusively with each other and in good faith the
commercially reasonable terms and conditions for a license and distribution
agreement for the marketing, sales and distribution by Orion of the Product in
Scandinavia for use in the Field (excluding the Orion Field in the Orion
Territory), such negotiations to be completed within one hundred and eighty
(180) days from the date of Orion's notification to GTX. Any deadlines may be
extended by mutual agreement upon reasonable request. If Orion fails to provide
written notification to GTX by the end of the thirty (30) day period; Orion
notifies GTX that it does not wish to enter into negotiations; or the Parties,
despite conducting good faith negotiations, are unable to finalize the material
commercial terms of agreement within such one hundred and eighty (180) day
period (any such event, a "Termination of the Orion Right"), Orion shall have no
further right under this Agreement to market, sell and distribute the Product in
Scandinavia and GTX shall be free to offer to or enter into an agreement with
any Third Party or any GTX Affiliate with respect to such activities after the
Termination of the Orion Right occurs.

             2.4.3 In the event that GTX's Unaffiliated Sublicensee for Product
for use in the Field in the USA does not obtain the right and license to sell,
have sold, import, market and distribute the Product in the Field in Europe at
the time of execution of the sublicense agreement for the Product for use in the
Field in the USA, then Orion shall, on the terms and conditions of Sections
2.4.1 and 2.4.2, have a right of first negotiation to negotiate in good faith an
agreement(s) under commercially reasonable terms and conditions regarding the
marketing, sales, and/or distribution of the Product for use in the Field in
Europe.

         2.5 USE OF TOREMIFENE BY GTX FOR RESEARCH. Subject to Sections
2.1.1(ii) and 14.6.2, GTX may use the Powder provided to it pursuant to Section
14.6.2 to perform stability studies and other activities with respect to
Products for use in the Field that are necessary for supporting Regulatory
Approval of Products or expanding the indications for Products within the Field.
GTX shall, upon Orion's request therefor, provide Orion with written updates of
any and all activities undertaken by or on behalf of it pursuant to this Section
2.5, and with the results thereof in reasonable detail.

         2.6 PROHIBITED ACTIONS. During the Term of this Agreement, Orion shall
not grant any rights to any Third Party that are inconsistent with the licenses
granted to GTX pursuant to Section 2.1.1.

3.       PAYMENTS

         3.1 TYPES OF PAYMENTS. For the rights, privileges and licenses granted
hereunder, GTX shall pay Orion in the manner provided as follows:

             3.1.1 In the event GTX or its Affiliate receives Upfront and
Milestone Income (as defined in Section 3.1.1(c)), GTX shall pay Orion as
follows:

                   (A) Any Upfront and Milestone Income for the sublicensing of
Product rights in the Prostate Cancer Field shall first be applied to [ * ] both
prior to and after the Effective Date with respect to the [ * ] and also for the
[ * ].

                   (B) Upon full reimbursement of such [ * ] pursuant to Section
3.1.1(a), any remaining Upfront and Milestone Income (the "Net Upfront and
Milestone Income") shall then be paid by GTX to Orion as follows:

                       (I) GTX shall pay Orion [ * ] of the portion of Net
Upfront and Milestone Income that is [ * ]; and

                       (II) [ * ] of the portion of the Net Upfront and
Milestone Income that is [ * ].

                   (C) For the purposes of this Agreement, "Upfront and
Milestone Income" shall mean any bona fide consideration (either in cash or
non-cash form) received by GTX or its Affiliate from a GTX Unaffiliated
Sublicensee for sublicensing GTX's rights in and to the Product for use in the
Prostate Cancer Field in the GTX Territory excluding: (i) Royalty Income (as
defined in Section 3.1.5); (ii) cost of goods payments for supply of Product
manufactured by Orion and supplied at the prices set forth in Article 14 herein
below, or payments to reimburse GTX's fully burdened costs of manufacturing or
having manufactured Product by or on behalf of GTX as permitted under this
Agreement; (iii) in the form of a loan; or (iv) for the purchase of an equity
interest in GTX (except to the extent such purchase price is a Premium over the
fair market value of such stock, in which case the Premium, but not the portion
of such price that is at the fair market value of such stock, shall be included
in Upfront and Milestone Income). Notwithstanding the foregoing, if GTX receives
Upfront and Milestone Income received in the form described in (ii) or (iii)
[ * ]. For example and without limitation, [ * ].

             3.1.2 If GTX is Acquired prior to the first Regulatory Approval of
Product for use in the Prostate Cancer Field, then GTX shall pay to Orion an
amount equal to the lesser of one million dollars ($1,000,000) or one percent
(1%) of the fair market value of GTX at the time of such acquisition. "Acquired"
means that GTX either (i) sells all or substantially all of its assets to a
Third Party, or (ii) is merged with or consolidated or reorganized into a Third
Party, or becomes a subsidiary of a Third Party, and, as a result of such
transaction, the stockholders of

GTX immediately prior to such transaction own less than fifty percent (50%) of
the surviving parent entity.

             3.1.3 ROYALTIES PAYABLE ON COMMERCIAL SALES OF FARESTON PRODUCT
UNTIL PRODUCT ROYALTY ADJUSTMENT DATE.

                   (A) For commercial sales of the Fareston Product by GTX or
its Affiliates after the Restatement Date, until the earlier to occur of (y) the
[ * ] or (z) the [ * ] of a Product for use in the Prostate Cancer Field (any
such Product in the Prostate Cancer Field, hereinafter referred to as a "New
Product", and the date that is the earlier to occur of (y) or (z), hereinafter
referred to as the "Product Royalty Adjustment Date"), GTX shall pay to Orion a
running royalty on Net Sales of Fareston Product by GTX, its Affiliate or its
Unaffiliated Sublicensee, as follows:

                       (I) Up until the end of the calendar month immediately
preceding the month in which the [ * ] occurs, the royalty due to Orion with
respect to Net Sales of the Fareston Product by GTX, its Affiliates and/or
Unaffiliated Sublicensees in the USA shall be [ * ] of Net Sales of Fareston
Product.

                       (II) Commencing upon the first day of the calendar month
in which the [ * ] occurs, and for the [ * ] the royalty due to Orion with
respect to Net Sales of the Fareston Product shall be [ * ] of Net Sales of
Fareston Product by GTX, its Affiliates and/or Unaffiliated Sublicensees during
such period of time, or (B) [ * ] of the MAT Net Sales of Fareston Product (as
calculated and defined in Section 3.1.3(b)).

                       (III) Upon the first day of the [ * ] occurs, and for the
[ * ] the royalty due to Orion with respect to Net Sales of Fareston Product by
GTX, its Affiliates and Unaffiliated Sublicensees shall be [ * ] of Net Sales of
Fareston Product by GTX, its Affiliates and Unaffiliated Sublicensees during
such period of time, or (B) [ * ] of [ * ] MAT Net Sales of Fareston Product.

                   (B) The Parties have agreed to use a moving annual total
("MAT") of sales of Fareston Product in the USA in calculating royalties due on
Net Sales of Fareston Product in the USA during [ * ] of the first New Product,
which MAT takes into account and reflects [ * ] during such period of time. Such
MAT shall be based upon (i) the [ * ] of such New Product and (ii) the actual
Net Sales of the Fareston Product in the USA during the [ * ] as follows: First,
the "Correction Factor" shall be calculated, which shall be equal to the Net
Sales of Fareston Product by GTX, its Affiliates and/or Unaffiliated
Sublicensees in the USA during the [ * ] occurs, divided by the Net Sales of
Fareston Product during the [ * ] occurs in the USA, provided that in no event
will the Correction Factor be [ * ]. Then, the "MAT Net Sales of Fareston
Product" shall be calculated, which shall be equal to the Correction Factor
multiplied by actual Net Sales of the Fareston Product during [ * ] occurs.

                   (C) For example and without limitation, if the Net Sales of
the Fareston Product have been [ * ] for [ * ] prior to the [ * ] occurs, and
[ * ] for [ * ] preceding the beginning of the [ * ] occurs, then the Correction
Factor would be [ * ]. Accordingly, the MAT

                                       13.



Net Sales of Fareston Product would be [ * ] of the actual Net Sales of the
Fareston Product during the [ * ].

                   (D) Commencing upon the Product Royalty Adjustment Date, the
royalty for Fareston Product shall be paid pursuant to Section 3.1.4 and shall
no longer be due pursuant to Sections 3.1.3(a) and (b).

                   (E) For clarity, sales of any New Product shall not be
included in the calculation of Net Sales of Fareston Product under this Section
3.1.3, but shall instead be subject to the royalty due pursuant to Section
3.1.4, no matter when such sales occur.

             3.1.4 ROYALTIES PAYABLE ON OTHER COMMERCIAL SALES OF PRODUCT.
Except as provided for the Fareston Product prior to the Product Royalty
Adjustment Date in Section 3.1.3, GTX shall pay to Orion a royalty on Net Sales
of Product by GTX or its Affiliates, equal to [ * ] of Net Sales of such
Products, on a country by country basis, subject to the provisions of Sections
3.1.8 and 21.2.2.

             3.1.5 Subject to the provisions of Sections 3.1.8 and 21.2.2, and
except as provided for the Fareston Product prior to the Product Royalty
Adjustment Date in Section 3.1.3, in the event GTX receives running royalty
income from GTX Unaffiliated Sublicensees for sublicensing GTX's rights in and
to any Product and/or based upon sales by GTX Unaffiliated Sublicensees of any
Product in the GTX Territory ("Royalty Income"), GTX shall pay Orion the lesser
of, on a country by country basis, either (a) [ * ] of such Royalty Income; or
(b) [ * ] of such Product by such GTX Unaffiliated Sublicensees provided,
however, that in no event shall the amounts due to Orion pursuant to this
Section 3.1.5 be [ * ] of Net Sales of such Product by such GTX Unaffiliated
Sublicensees.

             3.1.6 Notwithstanding Sections 3.1.3 through 3.1.5, if GTX enters
into an agreement with a Third Party to [ * ] and GTX is [ * ] (a [ * ]), then
in lieu of the payments to Orion under Sections 3.1.3 through 3.1.5, GTX shall
pay to Orion [ * ] of [ * ] Additionally, GTX shall not be obligated to pay
Orion any amounts under Sections 14.4 or 14.6 for Product supplied to GTX for
the purpose of [ * ], as the Parties have agreed that the amounts due to Orion
pursuant to this Section 3.1.6 shall be in lieu of any payments that would
otherwise be due to Orion for the supply of such Product if this Section 3.1.6
were not applicable.

             3.1.7 As of December 31, 2000, an upfront license fee of four
hundred thousand dollars ($400,000) (the "Upfront License Fee"), was paid in
full by GTX to Orion. This payment shall be creditable by GTX against fees or
payments due to Orion with respect to Upfront and Milestone Income pursuant to
Section 3.1.1.

             3.1.8 If a Generic Product is sold in any Major Country of the GTX
Territory, and, for two (2) succeeding Calendar Quarters the Sales of Generic
Product in that country [ * ] of the sales of Product (calculated on a unit
basis) in that country by GTX, its Affiliates and Unaffiliated Sublicensees,
then the royalty on Net Sales owed by GTX to Orion under Section 3.1.4 and the
payments due to Orion on Royalty Income pursuant to Section 3.1.5, respectively,
shall be reduced to [ * ] of the amount otherwise due to Orion pursuant to
either

                                       14.



Section 3.1.4 or 3.1.5, as applicable, with regard to such country with such
reduction to be applicable to the immediately succeeding Calendar Quarter only.

             3.1.9 For clarity, in no event shall a royalty be due with respect
to the sale of a given unit of Fareston Product pursuant to more than one of
Sections 3.1.3, 3.1.4 or 3.1.5.

         3.2 NON-REFUNDABILITY. All milestone payments GTX makes to Orion
pursuant to Section 3.1.1 shall be non-refundable once paid. However, if this
Agreement is terminated for any reason prior to a given milestone payment
becoming due or if the events specified for a given milestone payment do not
occur, then GTX shall have no obligation to make such milestone payment.

         3.3 ROYALTY REPORTS AND PAYMENTS. Commencing with the first Calendar
Quarter in which GTX, its Affiliates or a GTX Unaffiliated Sublicensees make the
First Commercial Sale of a Product, GTX shall provide Orion with a written
report of Net Sales and Royalty Income on a country-by-country basis within
forty-five (45) days after the last day of March, June, September and December
for Royalty Income accruing on Net Sales during the three (3) preceding calendar
months. Concurrently with the submission of each such written report, GTX shall
pay or cause to be paid to Orion the total amount of royalties shown to be due
thereon.

         3.4 CURRENCY. GTX shall make all Upfront and Milestone Income and
royalty payments to Orion pursuant to Section 3.1 in U.S. Dollars except that
GTX shall make all cost of goods payments to Orion pursuant to Article 14 in
euros. Where royalty payments are made, payments earned shall be first
determined by GTX in the currency of the country where the Net Sales on the
sales giving rise to payments were made and then converted directly to its
equivalent in U.S. dollars. The rates of exchange for converting the currencies
involved to U.S. dollars shall be the Foreign Exchange Rates quoted in the Wall
Street Journal rate on the last business day of the quarterly period in which
the royalty payments were earned.

         3.5 NO ROYALTIES PAYABLE BETWEEN AFFILIATES. No royalties shall be
payable to a Party on sales between the other Party, its Affiliates or between
the Party's Affiliates.

         3.6 NO MULTIPLE ROYALTIES. No multiple royalties shall be payable

multiple patents.

4.       LIAISON

         Representatives of the Parties shall meet bi-annually or as otherwise
agreed to review the development, sales and marketing activities for Product

Field in the GTX Territory, with the exact dates and locations of such meetings
to be mutually agreed upon. Such meetings shall alternate between GTX's and
Orion's offices or be at other mutually agreed upon locations, with each Party
to be responsible for the travel and living costs and expenses of its own
representatives attending such meetings.

5.       PAYMENT, RECORD KEEPING AND AUDIT RIGHTS

         5.1 METHOD OF PAYMENT. In the event of any required tax withholding,
the paying Party will provide the receiving Party with any relevant certificates
or documents required for national, state or local tax credit and reporting
purposes. Payments hereunder shall not be creditable against any other amounts
payable by a Party under this Agreement, except as otherwise expressly stated
herein. All payments shall be made by bank wire transfer (e.g., "SWIFT" or other
comparable electronic transfer method) to such account(s) as the receiving Party
shall designate beforehand in writing to the paying Party. Payments shall be
deemed paid once funds are freely available to the receiving Party at such
account(s).

         5.2 LATE PAYMENTS. The Party entitled to payment hereunder reserves the
right to charge the paying Party interest on any amounts owing from the paying
Party which are overdue by more than fourteen (14) business days at a rate of
[ * ] per annum, or the maximum rate allowed by law, whichever is lower,
calculated from the date any payment was due and payable.

         5.3 RECORD KEEPING AND AUDIT RIGHTS. Each Party shall keep or cause to
be kept accurate records relating to Net Sales, royalties, development and any
other costs and expenses subject to payment, deduction or reimbursement by
either Party to the other Party in sufficient detail to enable the amounts
payable hereunder to be determined. Upon the written request of either Party
(but not more frequently than once in any calendar year), the requesting Party
may retain an independent certified public accountant, subject to approval by
the other Party (which approval shall not be unreasonably withheld), to review
such records to verify the accuracy of the payments made or payable hereunder.
Such accountant shall be required to execute a confidentiality agreement in a
form reasonably acceptable to the audited Party and shall report to the auditing
Party only the amount of any underpayment or overcharge. Within ten (10)
business days after completion of such review, the Parties shall reconcile any
underpayment or overcharge. The auditing Party shall pay the cost of any review
of records conducted at its request under this Section. However, if the review
establishes underpayment or overcharge by the audited Party of over three
percent (3%) during the period of the review, the audited Party shall promptly
reimburse the auditing Party for the fees and expenses of the accountant. Such
audit rights may be exercised by the Parties only with respect to records for
the current calendar year and the preceding two (2) calendar years.

6.       GTX PRODUCT MARKETING AND SALES ACTIVITIES

         6.1 MINIMUM SALES REQUIREMENTS FOR USA.

             6.1.1 LEVELS OF MSRS. GTX shall have annual minimum sales
requirements for Product for use in the Prostate Cancer Field ("MSRs") in the
second year and fourth year after Product Launch in the USA for the Prostate
Cancer Field equal to [ * ] of GTX's annual Product Sales Projections (as
defined below) in the USA for the Prostate Cancer Field. To establish such
projections for the purpose of the foregoing sentence, GTX shall provide to
Orion quarterly Product Sales Projections in the USA for the Prostate Cancer
Field, within ninety (90) days after GTX, its Affiliate or Unaffiliated
Sublicensee completes the last pivotal clinical trial as provided in the GTX
Final Development and Registration Plan for Product in the Prostate Cancer Field
in

AMENDED.

                                       16.



the USA. The Parties shall set forth in Schedule D GTX's MSR obligations within
sixty (60) days after GTX provides such projections, and such MSRs shall be made
a part hereof. Beginning with the [ * ] year after Product Launch in USA for use
in the Prostate Cancer Field until the end of the Term, GTX shall have an annual
MSR equal to [ * ] of the average of GTX's Actual Product Sales (as defined
below) in the USA for Product in the Prostate Cancer Field for the [ * ].
"Product Sales Projections" means GTX's good faith estimates of the target
patient population in a given year for Products in the Prostate Cancer Field in
the USA, multiplied by the price per tablet of Product for use in the Prostate
Cancer Field in the USA that GTX plans to be able to charge during the [ * ]
after Product Launch. "Actual Product Sales" means GTX's, its Affiliate's or a
GTX Unaffiliated Sublicensee's actual Net Sales of Product in the Prostate
Cancer Field during a given year in the USA.

         For example, in year [ * ] if the target patient population in the USA
is [ * ] subjects in the Prostate Cancer Field and the Product would be consumed
by such patients [ * ] for the Prostate Cancer Field at a hypothetical price of
[ * ], GTX's Product Sales Projections for the USA would [ * ]. The hypothetical
price for a tablet set forth above is hypothetical and was only used for the
sole purpose of explaining the mechanism for calculating the Product Sales
Projections and MSRs. Nothing contained in such example shall be so construed to
deny the right of GTX to freely set its resale price of the Product.

             6.1.2 PRODUCT LAUNCH DATE. "Product Launch in USA" shall be
determined by the date on which the Product has received Regulatory Approval and
is commercially available in the USA as follows: (i) if such date occurs during
the first six (6) months of any calendar year (i.e., January 1-June 30), Product
Launch in USA shall be deemed to have occurred on January 1 of such calendar
year, and (ii) if such date occurs during the last six (6) months of any
calendar year (i.e., July 1-December 31), Product Launch in USA shall be deemed
to have occurred on January 1 of the following calendar year.

             6.1.3 ADJUSTMENT. GTX's annual Product Sales Projections for the
Prostate Cancer Field in the USA shall be subject to adjustment by written
agreement of the Parties, with a corresponding adjustment in the MSRs, in the
event of government intervention in given markets (including, but not limited
to, government mandated health care reforms, rebates or regulatory changes),
failure to obtain (or delay in obtaining) approval for a Product indication in
the Prostate Cancer Field, or other events or causes affecting the market for
the Product for use in the Prostate Cancer Field beyond the control of GTX,
including but not limited to lower than anticipated pricing approvals measured
on an aggregate basis throughout USA; GTX Patent Rights and/or Orion Patent
Rights invalidation, infringement or expiration; Product safety and/or efficacy
issues and/or major therapeutic advances materially affecting the market
potential for the Product for use in the Prostate Cancer Field (including but
not limited to new surgical procedures or introduction of new competitive
products with superior safety and/or efficacy profiles); or a Force Majeure
event (as described in Article 27).

             6.1.4 FAILURE TO ACHIEVE MSRS. If GTX's annual Product Sales in USA
for the Prostate Cancer Field are less than the MSRs in any applicable calendar
year, GTX shall, without prejudice to its payment obligations under Section 3.1,
pay Orion royalties corresponding to the "shortfall" between the actual
royalties paid by GTX for such year and the royalties which would have been
payable pursuant to Section 3.1 had GTX achieved the MSRs during such year,

AMENDED.

                                       17.



subject to Section 6.1.3. GTX's payment of such "shortfall" hereunder shall be
Orion's sole and exclusive remedy for GTX's failure to achieve MSRs in USA for
such year. However, if GTX fails to pay such "shortfall," then Orion may,
without prejudice to its right to such shortfall, also terminate this Agreement
pursuant to Section 21.2.2.

         6.2 NO MINIMUM SALES REQUIREMENTS OUTSIDE OF USA; NO MINIMUM SALES
REQUIREMENTS FOR SALES OF FARESTON PRODUCT. GTX shall not have any minimum sales
requirements with respect to sale of Product in any countries in the GTX
Territory outside of the USA. GTX shall not have any MSRs with respect to any
sales of Fareston Product or for any Product for use outside the Prostate Cancer
Field. GTx agrees that it will continue to sell Fareston Product in the Breast
Cancer Field in the USA until at least the Royalty Adjustment Date. If GTX
desires, after such date, to cease commercialization of the Fareston Product in
the Breast Cancer Field in the USA, then it may so notify Orion in writing. In
such case, the Parties shall discuss the reasons why GTX desires to cease such
commercialization activities. If Orion approves such proposal by GTX to cease
commercializing the Fareston Product in the Breast Cancer Field in the USA (such
approval not to be unreasonably withheld), then GTX may cease such activities.
Without limiting the foregoing, Orion may not withhold its approval of a
proposal by GTX under this Section 6.2 if GTX would be incurring, or based on
GTX's reasonable projections would be likely to incur, a loss if it continues to
commercialize Fareston Product in the Breast Cancer Field in the USA.

         6.3 MARKETING AND SALES EFFORTS IN THE MAJOR COUNTRIES.

             6.3.1 COMMERCIALLY REASONABLE OBLIGATION. On a country by country
basis, subject to Sections 6.3 and 6.4, during the period commencing with
Regulatory Approval in a Major Country, and for the remainder of the Term, GTX,
its Affiliate and/or a GTX Unaffiliated Sublicensee shall use commercially
reasonable efforts to promote, market, distribute and sell the Product for use
in the Prostate Cancer Field in such Major Country. For purposes of this Section
6.3, "commercially reasonable" shall mean using, in the relevant Major
Countries, an equivalent degree of effort as GTX, its Affiliate or a GTX
Unaffiliated Sublicensee would use to promote, market, distribute and sell a
product of its own that is of comparable market potential in such Major Country
during the same time period (as determined by consideration of, without
limitation, potential market, patent protection, and availability of competitive
products), including but not limited to, engaging in the following activities
(subject to any applicable U.S. FDA restrictions or other applicable legal
restrictions):

                   (A) Using reasonable diligence to establish and maintain good
business relationships with hospitals, health systems, doctors and other medical
professionals in accordance with standard and customary practices in such Major
Country;

                   (B) Using commercially reasonable efforts to establish and
maintain an adequate capacity of sales personnel consisting of reasonably
qualified personnel who have been certified, as trained by GTX, its Affiliate or
a GTX Unaffiliated Sublicensee, to promote and market the Product for use in the
Prostate Cancer Field in such Major Country, and to provide such sales force
with adequate sales and promotional materials for the Product;

BRACKETS, HAS BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS
AMENDED.

                                       18.



                   (C) Promoting and detailing the Product for use in the
Prostate Cancer Field throughout such Major Country, provided that GTX, its
Affiliate or a GTX Unaffiliated Sublicensee may, in its discretion use
relatively greater promotional and detailing efforts (i) in some Major Countries
than it uses in other of such countries, and (ii) in some parts of each Major
Country than in other parts thereof, consistent with its overall marketing plan;
and further provided, however, that the foregoing shall in no event be deemed to
limit GTX's its Affiliate or a GTX Unaffiliated Sublicensee overall obligations
under the first paragraph of this Section 6.3.1.

                   (D) Advertising the Product for use in the Prostate Cancer
Field in professional journals and publications and sponsoring or attending
appropriate symposia, trade exhibitions and medical education programs in a
manner equivalent to that used for GTX's, its Affiliate's or a GTX Unaffiliated
Sublicensee's, as applicable, own products of comparable market potential in
such Major Country; and

                   (E) Formulating and using reasonable efforts to implement
annual sales and marketing plans for the Product for use in the Prostate Cancer
Field in such Major Country and providing copies of such plans to Orion for
review and comment, provided that Orion shall not have approval rights with
respect to such plans.

             6.3.2 SALES OBJECTIVES AND OTHER FACTORS FOR THE USA. GTX and Orion
shall agree in writing upon annual target sales objectives for the Product for
use in the Prostate Cancer Field in the USA, commencing with the fourth calendar
year after First Commercial Sale of the Product for use in the Prostate Cancer
Field in the USA, provided that such annual target sales objectives shall not be
considered MSRs for any purposes, but instead shall be used by the Parties for
informational and planning purposes and shall be one (1) factor, among others,
to be considered in assessing whether GTX has complied with its commercially
reasonable obligations hereunder. GTX's level of sales and marketing expenses
for the Product for use in the Prostate Cancer Field in the USA and events or
causes affecting the market for the Product for use in the Prostate Cancer Field
beyond the control of GTX shall also be among the factors to be considered in
assessing whether GTX has complied with its commercially reasonable obligations
hereunder.

         6.4 PRODUCT LAUNCH.

             6.4.1 TIMING OF LAUNCH. GTX shall use commercially reasonable
efforts to launch the Product for use in a given indication in the Prostate
Cancer Field as soon as practical in every Major Country of the GTX Territory
where GTX, its Affiliates and/or GTX Unaffiliated Sublicensees have obtained
Regulatory Approval for such indication. Notwithstanding the foregoing, GTX, its
Affiliate or a GTX Unaffiliated Sublicensee may, acting in good faith in the
exercise of its reasonable business judgment, determine either to delay the
launch of the Product for use in a given indication in the Prostate Cancer Field
or not to launch the Product for use in a given indication in the Field in any
given country in the GTX Territory other than a Major Country, which decision to
delay or not to launch shall not be deemed a failure to use commercially
reasonable efforts. Further, GTX's, its Affiliates' or a GTX Unaffiliated
Sublicensee's decision to delay the launch of the Product for use in the
Prostate Cancer Field in any Major Country for up to six (6) months after GTX or
its Affiliates have obtained Regulatory

BRACKETS, HAS BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS
AMENDED.

                                       19.



Approval in such country, shall not be deemed a failure to use commercially
reasonable efforts pursuant to Section 6.3 to the extent that GTX can
demonstrate that such delay was attributable to bona fide business reasons
affecting the Product.

             6.4.2 DECISIONS NOT TO LAUNCH. GTX shall promptly notify Orion in
writing if GTX, its Affiliate or a GTX Unaffiliated Sublicensee, as applicable,
determines to delay the launch of the Product for use in a given indication in
the Prostate Cancer Field in any Major Country after obtaining Regulatory
Approval of Product therefor. If such decision is due to any reasons other than
the potential for, or the existence of, adverse business effects in such Major
Country, then such decision shall be deemed a material breach of this Agreement
pursuant to Section 21.2.2 and GTX shall be subject to the provisions of such
Section within thirty days (30) after GTX's decision not to launch in such Major
Country.

         6.5 MARKETING COSTS AND EXPENSES. Except as otherwise provided herein
or as otherwise mutually agreed by the Parties, GTX, its Affiliate or a GTX
Unaffiliated Sublicensee shall bear all costs and expenses connected with its
marketing and sales activities for the Product for use in the Field and its
performance under this Agreement.

         6.6 MARKETING PLANS AND REPORTS.

             6.6.1 MARKETING PLANS. GTX shall develop and provide to Orion by
October 31 of each year during the Term marketing and sales plans for the
Product for each Major Country for the following calendar year, commencing with
the calendar year in which Regulatory Approval is obtained in each respective
country. Such plans shall include the projected Annual Net Sales and the
projected advertising and promotion budgets for such year, and shall not be
applicable to the calculation of MSRs in connection with the sale of Products in
the Prostate Cancer Field in the USA pursuant to Section 6.1, for which GTX
shall separately provide information.

             6.6.2 MARKETING AND SALES REPORTS FOR PRODUCT. GTX shall provide to
Orion, within forty-five (45) days after the end of each calendar year, a
written marketing activities and sales report for each of the Major Countries in
which Product is launched. The report shall include at least a description of
sales, marketing and promotion activities and a list of scientific conferences
or other events involving the particular Product or its therapeutic area,
accompanied by a general description of the nature and extent of GTX's
participation in such conferences or events.

7.       GTX PRODUCT DEVELOPMENT AND REGISTRATIONS

         7.1 GTX DEVELOPMENT AND REGISTRATION ACTIVITIES.

             7.1.1 GTX ACTIVITIES. In accordance with the GTX Preliminary

clinical studies and other activities required for Regulatory Approval under the
GTX Final Development and Registration Plan. Without limiting the provisions of
Section 7.7, GTX shall use its commercially reasonable efforts to pursue such
development and registration activities under the GTX Final Development and
Registration Plan with the objective of filing applications for Regulatory
Approval in all Major Countries throughout the GTX Territory in the Prostate
Cancer Field according to the anticipated filing dates set forth in the GTX
Final Development and Registration Plan timetable [ * ]. GTX's Regulatory
Approvals in the GTX Territory shall be owned solely by GTX.

             7.1.2 ORION ACTIVITIES.

                   (A) Orion shall use its commercially reasonable efforts to
assist GTX in obtaining and maintaining the U.S. FDA Regulatory Approval of
Products in the Prostate Cancer Field and of the Fareston Product in the Breast
Cancer Field in the USA (including obtaining and/or maintaining the Orion
Product NDA and all related U.S. INDs filed with the U.S. FDA for such Products,
and any other required Regulatory Approvals in the Major Countries of the GTX
Territory relating to the manufacture, use, marketing or sale of Product for use
in the Prostate Cancer Field or of Fareston Product in the Breast Cancer Field
in the USA (by providing to GTX relevant information, documents and data in its
possession in relation to regulatory inquiries during the Regulatory Approval
process for Products, necessary additional letters of cross-reference or
authorization equivalent to those described in Section 7.5 to its registrations
for Product in the Orion Field in the Orion Territory, and other similar
assistance). Orion shall maintain the DMF filed with the U.S. FDA and all
equivalent regulatory authorities outside of the USA for Product as well as its
registrations for Product in the Orion Field in the Orion Territory during the
Term, provided that Orion may notify GTX that Orion intends to cease maintenance
of any such DMF and/or registration, in which case GTX shall have the right to
maintain such filing, at GTX's expense, by notifying Orion in writing within
thirty (30) days after it receives Orion's notice hereunder that it desires to
maintain such filing. If GTX elects to maintain such filing, Orion shall
cooperate reasonably with GTX to effect the transfer of such DMF and/or
registration to GTX.

                   (B) Orion shall perform any stability testing for the bulk
Orion Product to be manufactured and supplied by Orion to GTX that is required
by regulatory authorities in any Major Country. Such testing shall be provided
at no cost to GTX, except that GTX will reimburse Orion's direct costs of
performing any such stability testing that must be conducted solely for the [ *
] tablet of the Orion Product. Orion employees shall, at Orion's cost and
expense, have the right to participate in all FDA and other regulatory agency
meetings regarding the use of the Product in the Field.

                   (C) Orion shall have no obligation to research, develop,
register, commercialize any Product or carry out any studies or testing in
relation to Products, including without limitation with respect to any new or
additional strength, dosage form, formulation or route of administration of the
Orion Product or the Product, or provide any documentation, information or data
relating to the foregoing, except as expressly provided in Section 7.1.2(a) or
otherwise set forth in this Agreement, unless the Parties expressly mutually
agree otherwise in writing after the Restatement Date. Other than as expressly
agreed in this Agreement, Orion shall have no obligation to fund or pay for any
of the costs and expenses of such activities. All

studies, trials, tests, activities, documentation, data and information required
by any regulatory or other governmental agency or which is necessary or useful
for the research, development, registration or commercialization of the Product
shall, unless otherwise expressly agreed to herein as between the Parties, be
for the sole cost and responsibility of GTX.

             7.1.3 AUTHORIZATION LETTERS. Any regulatory filings (including
without limitation any DMFs that GTX may develop if it obtains the right to
manufacture Product) compiled and filed by or on behalf of GTX shall remain the
property of GTX, but GTX shall, upon request therefor by Orion, negotiate with
Orion the terms under which GTX would provide appropriate authorization letters
to relevant regulatory bodies to enable Orion to reference such regulatory
filings for purposes of applying for and supporting Orion's applications for
Regulatory Approval of products containing Toremifene outside the Field.

         7.2 FDA FILE. As of the Restatement Date, Orion shall have transferred
the Orion Product NDA and all Investigational New Drug Applications (as defined
in 21 C.F.R. Section 212) for Products filed with the FDA to the name of GTX, as
set forth in the Purchase Agreement.

         7.3 DEVELOPMENT AND REGISTRATION COSTS. Except as otherwise expressly
provided in this Agreement or otherwise mutually agreed in writing by the
Parties after the Restatement Date, GTX shall bear all costs and expenses
related to Product registration and regulatory activities (other than for
Product for the Orion Field in the Orion Territory), including without
limitation costs of filing, obtaining and maintaining all such Regulatory
Approvals throughout the GTX Territory, as well as all costs and expenses for
the research and development of the Product for use in the Field (other than for
Product for the Orion Field in the Orion Territory), provided that GTX shall not
be responsible for any costs related to the manufacture of the Orion Product
(except for payments that GTX must make to Orion pursuant to Section 7.1.2(b) or
Article 14 (such costs collectively referred to herein as "Manufacturing
Costs"). Except for the Manufacturing Costs or as otherwise expressly provided
in this Article 7, Orion shall bear no responsibility for any costs or expenses
related to Product registration, regulatory, research or development activities
in relation to the Product.

             7.3.1 DEVELOPMENT AND REGISTRATION COSTS PRIOR TO RESTATEMENT DATE.
The Parties agree that GTX shall, notwithstanding anything to the contrary in
the Original Agreement or otherwise, also bear all costs and expenses related to
Product research, development, registration, regulatory compliance and other
activities relating to the development of Product that were incurred prior to
the Amendment Date by GTX (excluding any Manufacturing Costs) (hereinafter
referred to as "Incurred Costs"). Consequently, except as set forth in Section
3.1.1, GTX shall forever release and discharge Orion of any and all claims that
it purports to have at the Amendment Date or may have thereafter against Orion
with respect to Incurred Costs.

         7.4 GTX DEVELOPMENT AND REGISTRATION PLAN.

             7.4.1 COMPLETION OF GTX FINAL DEVELOPMENT AND REGISTRATION PLAN.
The GTX Preliminary Development and Registration Plan for development and
registration of Product in the Prostate Cancer Field was attached to the
Original Agreement as Schedule B. GTX will prepare a GTX Final Development and
Registration Plan for such activities for each

Major Country in a timely fashion upon receiving approval from the appropriate
regulatory authority in each Major Country of a plan for regulatory approval in
that country. Immediately upon completion of the GTX Final Development and
Registration Plan for each Major Country, [ * ] GTX shall provide a copy of such
plan to Orion.

             7.4.2 ORION'S RIGHT TO COMMENT ON AND OBJECT TO PLAN. Orion shall
have the right to comment on each GTX Final Development and Registration Plan
for Product for the Prostate Cancer Field for each Major Country. Additionally,
Orion shall have the right to object to each GTX Final Development and
Registration Plan for each Major Country to the extent such plan could
reasonably be deemed to affect adversely Orion's development, commercialization,
sales or registration of Toremifene in the Orion Field in the Orion Territory or
outside the Field. GTX undertakes to change and/or amend the GTX Final
Development and Registration Plan for Product for the Prostate Cancer Field for
each Major Country to the extent Orion has so objected thereto as necessary to
alleviate or obviate such adverse effect. Orion shall provide GTX with such
comments and/or objections within thirty (30) days from Orion's receipt of the
GTX Final Development and Registration Plan.

             7.4.3 CHANGES TO SUCH PLAN. GTX may modify the GTX Final
Development and Registration Plan, as GTX deems necessary and consistent with
Section 7.4.1, but shall notify Orion of such changes. Any changes to the GTX
Final Development and Registration Plan for each Major Country shall also be
subject to Section 7.4.2.

         7.5 ORION DOCUMENTATION AND DATA.

             7.5.1 GTX ACCESS TO ORION KNOW-HOW. Orion has provided and shall
continue to provide GTX with copies of the Orion Know-How, documentation,
information and data listed or referenced in the GTX Preliminary Development and
Registration Plan, and GTX shall be authorized to use and reference the same in
its applications for Regulatory Approval and regulatory compliance activities in
relation to such Regulatory Approvals. Any Product Drug Master Files ("DMFs")
compiled or owned by Orion shall remain the property of Orion, but Orion shall,
upon reasonable request therefor by GTX, provide appropriate authorization
letters to relevant regulatory bodies in the GTX Territory within forty-five
(45) days from such request to enable GTX to reference such DMFs for purposes of
GTX's applications for Regulatory Approval and regulatory compliance activities
in the GTX Territory as provided for in Section 7.1. For the avoidance of doubt,
neither Party is obligated to disclose the contents of its DMFs to the other
Party.

             7.5.2 GTX ACCESS TO DATA. During the Term, Orion shall provide GTX,
within forty-five (45) days of receipt of a written request from GTX specifying
in detail the documentation, information and/or data requested, access to Orion
Know-How in Orion's control and possession (and freely disclosable) that GTX
reasonably requires for regulatory filings for the use of Product in the Field
in the GTX Territory, including any Orion Know-How concerning the use of the
Product in the Orion Field in the Orion Territory to the extent such information
may be reasonably required by GTX for such regulatory filings. In instances
where documentation, information and/or data requested are required by the U.S.
FDA or other regulatory agency to be submitted in a time frame shorter than
forty-five (45) days, GTX shall notify Orion, and GTX and Orion shall agree on a
shorter time frame for provision of such

materials within the time required by the FDA. In the event any of such Orion
Know-How is not in the control or possession of Orion but is controlled by a
Third Party, Orion and GTX shall discuss in good faith commercially reasonable
efforts that Orion may, at its discretion, decide to take to assist GTX in
accessing such Orion Know-How, provided that nothing herein shall obligate Orion
to take steps to arrange, or incur costs, to access such Orion Know-How from
such Third Party, and provided further that if requested by GTX, Orion will
grant GTX the necessary authorizations to approach any such Third Party for such
access. Upon GTX's request, Orion shall provide GTX with copies of such Orion
Know-How referenced in the preceding sentences only in such form and content as
is available to Orion, provided that, upon Orion's request, GTX shall reimburse
Orion for Orion's direct out-of-pocket cost of making such copies and providing
GTX with such Orion Know-How.

         GTX shall also provide to Orion quarterly reports summarizing GTX's
development activities for Products in the Field (excluding the Orion Field in
the Orion Territory).

             7.5.3 LETTER OF CROSS REFERENCE. Orion agrees that the Cross
Reference letter dated December 10, 1999 from Orion to GTX shall remain in
effect to the extent it enables GTX or its Affiliates to reference regulatory
filings for the Orion Product in all countries outside of the USA. Such Cross
Reference letter may not be revoked by Orion unless this Agreement is
terminated. During the Term, Orion shall permit GTX, its Affiliates and the GTX
Unaffiliated Sublicensees to reference, and shall provide GTX with an
appropriate authorization letter to enable GTX, its Affiliates and the GTX
Unaffiliated Sublicensees to reference, all applications or filings for
Regulatory Approval for Orion Products for use in the Orion Field and related
DMFs that are identified in Schedule E hereof (hereinafter "Orion Product
Approvals") for the purpose of applying for and supporting Regulatory Approval
of Products for use in the Field within the GTX Territory. Orion shall update
Schedule E from time to time during the Term to set forth all Orion Product
Approvals and DMFs that are owned and controlled by Orion. GTX recognizes that
Orion has obtained the Orion Product Approvals solely for the purpose of its
proprietary product Fareston(R), and that nothing herein shall be construed so
as to obligate Orion to maintain or cause to be maintained any Orion Product
Approvals solely for allowing GTX, its Affiliates and/or GTX Unaffiliated
Sublicensees to refer thereto, provided that during the Term, Orion shall not
withdraw such Orion Product Approvals in the absence of commercially justifiable
reasons in relation to Fareston(R). Orion shall, prior to withdrawing such Orion
Product Approvals, offer to GTX the right to maintain such approvals, at GTX's
expense. If GTX elects to maintain such approvals, Orion shall reasonably
cooperate with GTX to enable GTX to assume such responsibility.

             7.5.4 ADDRESS. All requests by GTX to Orion for documentation,
information or data, as agreed herein, shall be addressed only to the attention
of such person(s) as is/are designated in writing or in electronic form by Orion
from time to time.

         7.6 GTX REGISTRATION AND MARKETING APPROVAL APPLICATIONS. GTX, its
Affiliates and/or GTX Unaffiliated Sublicensees shall have the responsibility
and the right to submit registration applications for Regulatory Approval and
marketing and price approval of the Product for use in the Field within the GTX
Territory; provided, however, that GTX shall not have the responsibility to
submit such applications for approval of the Product for use in the Orion Field
in the Orion Territory.

                                       24.



         7.7 FAILURE TO FILE OR EXTEND. Orion shall have the right to terminate
its obligations under Section 7.1.2(a) and its obligations to manufacture and
supply to GTX Orion Product upon one hundred and eighty (180) days prior written
notice to GTX, if Regulatory Approval has not been granted for the Product for
use in the Prostate Cancer Field in the USA by December 31, 2009. Any such
notice hereunder shall be given no later than sixty (60) days after December 31,
2009, provided that GTX shall inform Orion in writing by December 31, 2009,
whether or not Regulatory Approval has been granted for the Product for use in
the Prostate Cancer Field in the USA by such date. The time for Orion to provide
notice to GTX of its decision to exercise its right with regard to the event
described above shall be deemed to commence upon the receipt by Orion of such
notice from GTX, provided that nothing shall be construed so as to prevent Orion
from exercising its right hereunder if Orion discovers, either by itself or
through a Third Party, that Regulatory Approval has not been granted for the
Product for use in the Field in the USA by December 31, 2009. Effective upon the
date that GTX receives any notice from Orion pursuant to this Section 7.7 and
during the Term, Orion hereby grants GTX a contingent license under the Orion
Patent Rights and Orion Know-How and all other patents and patent applications
owned or controlled by Orion during the Term that relate to the manufacture, use
or sale of Toremifene or Orion Product ("Manufacturing Patents") to make and
have made Product for use in the Field in the GTX Territory (except in the Orion
Field in the Orion Territory). Such license shall be exclusive and sublicensable
(but only for the purposes of having manufactured the Products for GTX, its
Affiliates or Unaffiliated Sublicensees). Orion shall as soon as practically
possible after providing any notice to GTX pursuant to this Section 7.7 provide
GTX with such then-existing manufacturing, process and quality control
procedures, documentation and other relevant know-how and information to the
extent reasonably necessary to enable GTX to exercise its manufacturing right
pursuant to this Section 7.7 (hereinafter "Product Manufacturing Know-How"),
including without limitation providing up to ten (10) person-days of technology
transfer assistance at GTX's site of manufacture of Product using Orion
personnel skilled in such manufacturing operations, at no charge to GTX.

         7.8 REIMBURSEMENT OF ORION COSTS. Except as provided for otherwise in
this Article 7, GTX shall reimburse Orion for all costs and expenses incurred by
Orion in fulfilling its obligations under this Article 7 with respect to
Products in the Field, subject to the following: (a) such reimbursable amounts
shall include costs of assistance provided by Orion for activities relating to
the Prostate Cancer Field only to the extent such costs (i) are incurred by
Orion after [ * ] or (ii) have been invoiced to GTX prior to [ * ]; (b) such
reimbursable amounts shall include costs of assistance provided by Orion for
activities outside of the Prostate Cancer Field and the Breast Cancer Field,
with the amounts described in this subsection (b) including Orion's [ * ]; (c)
such reimbursable amounts shall not include [ * ] and (d) such reimbursable
amounts shall not include [ * ]. Orion shall issue an invoice for all such
reasonable costs and expenses so incurred that are reimbursable hereunder during
each Calendar Quarter, and GTX shall effect payment of such invoice within
thirty (30) days from the date of the invoice.

8.       CONFIDENTIALITY AND PUBLICITY

         8.1 CONFIDENTIALITY OBLIGATION. Each Party shall hold the other Party's
Confidential Information (as defined below) of which it becomes informed in
connection with this Agreement or the Original Agreement in strictest confidence
and shall not disclose such Confidential Information to Third Parties or

                     (A) GTX shall have the first right but not the obligation,
to commence, at its own expense appropriate measures to enforce United States
Patent Nos. [ * ] against infringement by Third Parties, within a reasonable
period of time after GTX becomes aware of such infringement (including, but not

alleged Third Party infringement of said Orion Patent Rights, either by notice
from Orion or otherwise, GTX has not commenced a legal proceeding against such
infringement, or if at any time GTX discontinues the pursuit of such proceeding,

Party prior to the Restatement Date in such country with respect to enforcement

of such proceeding or any appeal thereof, GTX shall resume paying Orion the full
royalties in such country, and GTX shall also be liable for payment of any back

GTX's commencement, continuation or intervention in such proceeding shall be at

alleged or actual infringement of a Third Party patent or trademark or other
proprietary right as a result of Orion's, its Affiliate(s) or Unaffiliated
Sublicensee(s') manufacturing of or selling Orion Product to GTX, or GTX, its
Affiliates, or GTX Unaffiliated Sublicensees making, having made, marketing,
using or selling the Product in GTX Territory for use in the Field, each Party
shall so notify the other Party and the Parties shall confer regarding the basis
for such claim, and discuss how the Parties may resolve the situation. Orion
shall have the right to suspend its manufacture and supply of the Orion Product
in and/or to the part of the GTX Territory so affected upon twenty (20) days
prior written notice to GTX pending resolution of such claim or any related
infringement litigation, if necessary to mitigate damages that may be incurred.
If Orion exercises its rights hereunder, the Parties shall thereafter discuss
from time to time whether the situation has been resolved and, accordingly,
whether Orion is in a position to resume the supply of Orion Product pursuant to
this Agreement.

Approval for Product for use in the Field, excluding the Orion Field in the
Orion Territory. Upon ordering Powder from Orion, GTx shall provide Orion with a
detailed description of such study(ies) and the expected amount of Powder needed
for said study(ies).

         As consideration for Orion's agreement to provide the Powder to GTX,
all results, data, information, inventions, memoranda, reports, discoveries,
work products and other results (including without limitation any patents(s)
granted thereon), which are conceived, derived, reduced to practice, made and/or
developed by or on behalf of GTX and arising out of or relating to the use of
the Powder (hereinafter referred to as "Results") shall be jointly owned by GTX

Orion hereby grants to GTX an exclusive, royalty-free, worldwide license, with
the right to grant sublicenses, under Orion's joint interest in the Results and
any intellectual property rights relating thereto, for use in developing, using,
having used, selling, having sold, importing, marketing and distributing
products in the Field (excluding in the Orion Field in the Orion Territory), to
the extent such rights are not otherwise included in the Orion Patent Rights or
Orion Know-How licensed to GTX pursuant to Section 2.1.1.

         Any use of the Results by GTX other than for the purposes of this
Agreement shall not be permitted without the express written consent of Orion,
which Orion may withhold at its sole discretion.

         Without prejudice to the foregoing, the Results shall be deemed both
Orion's and GTX's Confidential Information and shall be used and treated for
purposes of Section 8 of this Agreement as Confidential Information of the other
Party. GTX shall promptly disclose to Orion all Results immediately when such
Results are available.

         GTX and Orion shall mutually determine whether or not any of the
Results provide the basis for any patentable inventions. If both Orion and GTX
consider that patents for any such inventions involving Results should be
sought, then such applications shall, in accordance with what has been stated
herein above, be filed in the Parties' joint name, and the Parties shall share
equally all costs of filing, prosecuting and maintaining relevant patent
applications and patents. The Parties shall negotiate in good faith on the
division of responsibilities with regard to drafting, filing, prosecuting and
maintaining the relevant patent applications and patents. If the Parties do not
decide that patent application(s) should be filed for any patentable inventions

BRACKETS, HAS BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS
AMENDED.

                                       38.



Orion Product to GTX, its Affiliates and GTX Unaffiliated Sublicensees during
the Term, notwithstanding any conflicting terms and conditions set forth in
GTX's forecast, order or purchase documents or in Orion's sale or acceptance
documents and any such conflicting terms are hereby expressly rejected.

         14.8 PRICE ADJUSTMENT FOR COMMERCIAL SUPPLY. It is agreed upon by the
Parties that the price of the [ * ] tablet of Orion Product to GTX, its
Affiliates or Unaffiliated Sublicensees shall be reduced below [ * ] based upon
attaining certain milestone purchases of Product as follows: if GTX purchases
annually an aggregate amount of [ * ] of tablet [ * ] the price of the tablet
shall be [ * ] per [ * ] tablet. Similarly, (i) the price to GTX of the [ * ]
tablet of Orion Product shall be reduced if GTX purchases annually [ * ] of the
[ * ] tablets such that the price per [ * ] tablet of Orion Product shall be
[ * ] and (ii) the price to GTX of the [ * ] tablet of Orion Product shall be
reduced if GTX purchases annually [ * ] of the [ * ] tablets such that the price
per [ * ] tablet of Orion Product shall be [ * ]. If a price adjustment is
triggered under this Section 14.8, then the adjusted price shall apply to the
entire amount of the relevant tablets purchased during the relevant year. Orion
shall within thirty (30) days after the end of such year, pay to GTX an amount
equal to the number of relevant tablets actually purchased during such year,
multiplied by the difference between the price paid by GTX for supply of the
relevant tablets and the lower price that is actually applicable due to the
adjustment to be made pursuant to this Section 14.8.

         14.9 TERMINATION OF PRODUCT SUPPLY. Orion shall, at its sole
discretion, have the right upon providing [ * ] prior written notice thereof, to
terminate its obligations under this Article 14 relating to the manufacture and
supply of Orion Product and/or Toremifene (pursuant to Section 14.6.2) in the
event that Orion permanently ceases the manufacture of Toremifene and/or Orion
Product. For the avoidance of doubt, the right of termination relating to the
manufacture and supply of Orion Product and/or Toremifene set forth in this
Section 14.9 shall not restrict or alter Orion's rights under Section 7.7. In
the event that Orion so terminates such obligations, Orion shall grant GTX a
contingent license under the Orion Patent Rights, Orion Know-How and the
Manufacturing Patents to make and have made Product for use in the Field in the
GTX Territory (except for use of the Product in the Orion Field in the Orion
Territory) during the Term, with such license to be exclusive in the Field (but
excluding the Orion Field in the Orion Territory) and sublicensable (but only
for the purpose of having Products manufactured for GTX, its Affiliates or
Unaffiliated Sublicensees). Such license shall become effective upon GTX's
receipt of notice from Orion under this Section 14.9. Orion shall during such
[ * ] notice period, and as soon as practically possible after GTX's written
request, provide GTX with Product Manufacturing Know-How to the extent
reasonably necessary to enable GTX to exercise its back-up manufacturing right
pursuant to this Section 14.9, including without limitation providing up to ten
(10) person-days of technology transfer assistance at GTX's site of manufacture
of Product using Orion personnel skilled in such manufacturing operations, at no
charge to GTX.

provided for in Section 11.2, no representation, warranty, commitment or
obligations given, made or undertaken by Orion in this Agreement shall apply
with regard to any Product manufactured by a party other than Orion, its
Affiliates or subcontractors, including without limitation any Product
manufactured by or on behalf of GTX under its stand-by and other manufacturing
rights pursuant to Section 7.7, 14.9, 16.1, 17.3.2, 17.4 or 21.2.2.

              15.1.2 LIMITATIONS. Except as otherwise expressly stated herein,
no warranties or representations, express or implied are made or shall be deemed
to have been made by Orion, its Affiliate or subcontractor including without

              15.3.1 GTX INSPECTION AND ANALYSIS. GTX shall inspect and analyze
a representative sample of Orion Product from batches supplied by Orion promptly
after receipt. If, after inspection, GTX reasonably believes the shipment does
not meet the Specifications, GTX shall notify Orion in writing within thirty
(30) days after GTX's receipt of any such goods. If GTX does not so notify
Orion, GTX shall be deemed to have waived all claims against Orion for said
quantity delivered, except for any latent defects that could not have been
reasonably discovered upon such inspection, which defects shall be notified by
GTX to Orion within fourteen (14) days from discovery of same. Any claims by GTX
regarding goods delivered shall specify in reasonable detail the nature and
basis for the claim and cite relevant Orion lot numbers or other information to

required to take any action with respect thereto. Orion shall review any such
claim of nonconformity made by GTX within thirty (30) business days of receipt
of GTX's notice under Section 15.3.1 and conduct any required testing of the
goods involved as soon as possible, but in no event later than forty-five (45)
days after receipt thereof, or earlier if the U.S. FDA or any corresponding
regulatory authority in the GTX Territory requires an earlier response from
Orion. If such review and testing by Orion (or testing by an independent
laboratory as set forth below) confirms that a claimed quantity does not meet
the Specifications, then, at Orion's expense, GTX shall dispose of or return
such quantity involved as Orion shall direct in writing and Orion shall replace
such quantity with conforming goods as soon as possible, but in no event later
than sixty (60) days after testing is completed, which shall be GTX's sole and
exclusive remedy for such non-conformity. If the Parties fail to agree as to
whether a delivered quantity meets the Specifications, then the Parties shall
have the batch in dispute analyzed by a mutually agreed upon independent testing
laboratory located in the country in which Orion Product to which goods relate
is intended for resale, or, if the Parties agree, in Finland. Such laboratory's
determination shall be deemed final as to any dispute over the Specifications

therefore by Orion, provide Orion with copies of representative samples of
materials which GTX, its Affiliates and GTX Unaffiliated Sublicensees intend to
use in connection with the marketing, promotion and sale of the Product thirty
(30) days prior to their first use thereof, provided that nothing herein or
otherwise, including without limitation any request by Orion to be furnished
with such materials or review of same, shall be construed as Orion assuming any
liability or responsibility for such materials or their conformity to all legal
requirements in any country of the GTX Territory in which the Product is sold
and such request and/or review by Orion of such materials shall be without
prejudice to the first sentence of this Section 15.5. GTX, its Affiliates, or
GTX Unaffiliated Sublicensee shall register, promote, market and sell the

Affiliates or Unaffiliated Sublicensees, except with respect to each of (A) and
(B) to the extent that such Losses are caused by activities for which GTX must
defend, indemnify and hold harmless pursuant to Section 15.6.2.

              15.6.2 GTX INDEMNIFICATION. GTX shall defend, indemnify and hold
Orion, its Affiliates, and its and their the officers, directors and employees
harmless from and against any and all Losses claimed by any Third Party for any
property or other economic loss or damage, injury or death suffered by it to the
extent the same is determined to have been caused by (A) a breach by GTX of [ *
]; (B) the negligence, fault, willful wrongdoing or any other act or omission,
or material breach of this Agreement by GTX, its Affiliates or Unaffiliated
Sublicensees; (C) the manufacture, use, sale, importation, distribution, and/or
marketing of the Product by GTX, its Affiliates or Unaffiliated Sublicensees in
the Field in the GTX Territory, including without limitation any product
liability claim for property or other economic loss or damage, injury or death
suffered by a Third Party arising out of or relating to the Product or Other
Product or use thereof, except with respect to each of (B) and (C) to the extent
that such Losses are caused by activities for which Orion must defend, indemnify
and hold harmless GTX pursuant to Section 15.6.1.

         15.7 CONDITIONS FOR INDEMNIFICATION. With respect to any
indemnification obligations of either Party to the other Party under this
Agreement, the following conditions must be met for such indemnification
obligations to become applicable: (A) the indemnified Party shall notify the
indemnifying Party promptly in writing of any claim which may give rise to an

                                       42.


         15.8 LIABILITY INSURANCE. GTX shall procure and maintain insurance,
including product liability insurance, adequate to cover its obligations
hereunder and which are consistent with normal business practices of prudent
companies commercializing products of similar nature that present similar
liability risks. It is understood that such insurance shall not be construed to
create a limit of GTX's liability with respect to its any of its obligations
hereunder, including without limitation its indemnification and compensation
obligations under this Agreement. GTX shall provide Orion with written evidence
of such insurance (including without limitation financial information that
describes the amounts available under such insurance) upon request. This Section
15.8 shall survive the termination expiration of this Agreement for ten (10)
years for whatsoever reason.

16.      STANDBY MANUFACTURING RIGHTS; INVENTORY MAINTENANCE

         16.1 INABILITY TO MANUFACTURE OR SUPPLY. If Orion is unable to supply
or manufacture Orion Product, as ordered pursuant to Sections 14.1.2 and 14.3.2,
for ninety (90) or more consecutive days after the agreed delivery time for any
reason (including but not limited to a Force Majeure event), save as for reasons
arising from acts or omissions of GTX, its Affiliates and/or its Unaffiliated
Sublicensees, including without limitation failure by GTX, its Affiliates and/or
its Unaffiliated Sublicensees to notify Orion of Orion's failure to deliver
Orion Product ordered pursuant to Sections 14.1.2 and 14.3.2, then GTX may, at
its option, responsibility and expense, elect to manufacture or have a Third
Party manufacture Toremifene and/or Orion Product for use in manufacturing and
selling the Product for use in the Field anywhere in the GTX Territory (except
for use in the Orion Field in the Orion Territory) until such time as Orion can
demonstrate to GTX's reasonable satisfaction that Orion is capable of resuming
the manufacture of Toremifene and/or Orion Product, as applicable. To the extent
necessary to implement such standby manufacturing rights, Orion hereby grants
GTX a contingent license under the Orion Patent Rights, Orion Know-How and
Manufacturing Patents to make and have made Toremifene and/or Orion Product for
use in the Field in the GTX Territory (except for use in the Orion Field in the
Orion Territory). Such license shall be exclusive and sublicensable (but only
for the purpose of having Products manufactured for GTX, its Affiliates or
Unaffiliated Sublicensees), with such license to become effective only under the
circumstances specified in the preceding sentence. In such case, Orion shall as
soon as practically possible provide GTX with Product Manufacturing Know-How to
the extent reasonably necessary to enable GTX to exercise its back-up
manufacturing right pursuant to this Section 16.1, including without limitation
providing up to ten (10) person-days of technology transfer assistance at GTX's
site of manufacture of Product using Orion personnel skilled in such
manufacturing operations, at no charge to GTX. Orion shall promptly notify GTX
in writing of any circumstances rendering it unable to manufacture Product and
the estimated duration of such circumstances. GTX's standby-manufacturing rights
under this Section 16.1 shall be GTX's sole and exclusive remedy for Orion's
failure to manufacture or have manufactured Orion Product for supply to GTX
under Article 14.

         16.2 BACK-UP MANUFACTURING RIGHT. GTX shall have the right to require
Orion to qualify and maintain the qualification for, at GTX's expense (as
described below), a back-up facility(ies) for use in manufacturing Product for
supply to GTX pursuant to Article 14 at any time after GTX's good faith
forecasted Net Sales of Products provided pursuant to Section 14.3 [ * ] in a
given Year, or actual Net Sales for Product in any given Year [ * ]. GTX shall
exercise


[ * ] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY
BRACKETS, HAS BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS
AMENDED.

                                       43.



such right by written notice to Orion. Promptly after receiving such notice,
Orion and GTX shall meet to discuss the manner in which Orion proposes to
qualify and maintain the qualification for such back-up manufacturing
facility(ies) (for example, by qualifying a site owned by Orion or by engaging a
Third Party manufacturer to qualify another facility), the timing for qualifying
such facility(ies), and Orion's estimated costs incurred directly in connection
with qualifying such facility(ies) (which costs may include, by way of example,
Orion's costs of obtaining Regulatory Approvals necessary to enable the sale in
the Territory of Product manufactured at such site). Orion shall promptly
thereafter, subject to agreement on reimbursement by GTX of Orion's related
costs and expenses, qualify such back-up facility and maintain the qualification
for such facility (including obtaining relevant Regulatory Approvals and making
appropriate regulatory filings) to assure continued supply of Product in the
event Orion is unable to supply Products in the amounts ordered pursuant to
Article 14. GTX shall reimburse Orion for [ * ] or [ * ] the Parties. Nothing in
this Section 16.2 shall be deemed to limit Orion's obligations under Article 14,
or to prevent GTX from seeking any remedies available to it under law or in
equity for any breach by Orion under such Sections.

         16.3 MAINTENANCE OF INVENTORY. Orion shall, at all times during the
Term, maintain or have maintained, either itself or through a subcontractor, an
amount of Toremifene and other raw materials critical for the manufacture of
Products containing such Toremifene sufficient to manufacture the amount of
Product forecasted to be ordered by GTX pursuant to Section 14.3 during the
subsequent [ * ] period of time. The Parties will agree upon an appropriate
amount of reserve supplies to be maintained by Orion during the first [ * ]
following the First Commercial Sale of Product in the Prostate Cancer Field at
the time GTX provides an update to its forecasted requirements to support launch
of Product in such field pursuant to Section 14.1. Such supplies shall serve as
a reserve supply to be used by Orion solely to manufacture Product for GTX if
any shortfall in the amount of Product supplied by Orion pursuant to Article 14
occurs or is reasonably anticipated to occur. Nothing in this Section 16.3 shall
be deemed to limit Orion's obligations under Article 14.

17.      MANUFACTURING INSPECTIONS AND CHANGES

         17.1 REGULATORY INSPECTIONS. Each Party shall allow representatives of
the U.S. FDA and any other regulatory agency or authority with jurisdiction over
the manufacture, marketing and distribution of the Product to tour and inspect
all facilities utilized by such Party in the manufacture, testing, packaging,
storage, and shipment of Product sold under this Agreement, and shall co-operate
with such representatives in every reasonable manner. Upon notification by the
U.S. FDA or any other regulatory agency of such agency's intent to conduct an
inspection, the Party receiving such notification will immediately inform the
other Party of such inspection with such advance notice as to allow the other
Party to have representatives present during such inspection (to the extent such
presence is allowed by such regulatory agency). Each Party shall also provide
the other Party with a copy of any U.S. FDA Form 483 notices of adverse
findings, regulatory letters or similar notifications it receives from any other
governmental authority setting forth adverse findings or non compliance with any
applicable laws, regulations or standards relating to the Product within five
(5) days of its own receipt thereof. Each Party shall also provide the other
Party with a copy of its proposed written response to such governmental
authority before submission and shall incorporate any changes thereto which the
other Party may reasonably request.

COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS
AMENDED.

                                       44.


         17.2 ORION-INITIATED MANUFACTURING CHANGES. Save as for changes
required under applicable laws and regulations or by any competent regulatory or
other authority, during the Term, Orion shall not make any material changes to
its manufacturing operations for Toremifene or Orion Product to be supplied to
GTX pursuant to this Agreement, without informing GTX prior to such changes;
provided that if such changes would require GTX to make additional filings with
regulatory authorities or to seek additional Regulatory Approvals for Orion
Product, then Orion shall not make such change without GTX's prior written
consent, such consent not to be unreasonably withheld, conditioned or delayed.

         17.3 GTX-INITIATED MANUFACTURING CHANGES.

              17.3.1 GTX REQUEST FOR MANUFACTURING CHANGES. Prior to Orion
providing GTX with notice pursuant to Section 14.9, GTX may, from time to time
during the Term and as agreed in this Section 17.3, make a written and detailed
request for changes in Orion's manufacturing operations, or the Specifications,
for Toremifene or Orion Product. Such changes that are required and mandatory
under applicable laws and regulations in a Major Country shall be deemed
"Required Manufacturing Changes", and such changes that are intended to promote
quality control/quality assurance, and/or to achieve greater efficiency or cost
savings in the manufacturing process but are not so required and mandatory shall
be deemed "Other Manufacturing Changes".

              17.3.2 REQUIRED MANUFACTURING CHANGES. Provided that GTX furnishes
Orion with evidence of Required Manufacturing Changes, Orion shall commence the
implementation of Required Manufacturing Changes as soon as practicable, but in
no event later than (i) ninety (90) days after receipt of GTX's request (or
within such other longer time period as may be mutually agreed upon by the
Parties if implementation within ninety (90) days is impossible or reasonably
impractical, such agreement not to be unreasonably withheld, conditioned or
delayed by GTX) or (ii) earlier if required by the U.S. FDA or any corresponding
regulatory authority in a Major Country. If Orion does not commence the
implementation of Required Manufacturing Changes within the time period
referenced in the preceding sentence or does not notify GTX in writing that
Orion disputes whether GTX's requested changes are Required Manufacturing
Changes, then GTX shall have the option to exercise standby manufacturing rights
for Toremifene and Product pursuant to Section 16.1 until such time as Orion
implements such Required Manufacturing Changes. If Orion notifies GTX in writing
that Orion disputes whether GTX's requested changes are Required Manufacturing
Changes, the Parties shall resolve such dispute by reference to a mutually
agreed upon independent Third Party regulatory expert as soon as possible for a
binding determination of whether the requested changes are Required
Manufacturing Changes. If such independent Third Party regulatory expert
determines that GTX's requested changes are Required Manufacturing Changes,
Orion shall implement such changes as soon as possible. Any modification to the
Specifications that is necessary to implement or reflect a Required
Manufacturing Change shall be deemed to be included in the Specifications, and
any Products manufactured thereunder by Orion shall be deemed Orion Products.

              17.3.3 OTHER MANUFACTURING CHANGES. Orion shall give due
consideration to making Other Manufacturing Changes proposed by GTX. Orion shall
within sixty (60) days from receipt of GTX's written request for Other
Manufacturing Changes provide GTX a written

BRACKETS, HAS BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS
AMENDED.

                                       45.



response to such request indicating whether it would be willing to discuss, and
as appropriate, negotiate the terms and conditions under which Orion would be
willing to implement such Other Manufacturing Changes.

         17.4 NEW DOSAGE STRENGTHS AND FORMULATIONS. Upon written request by
GTX, the Parties shall meet in person or by teleconference to discuss, and as
appropriate, negotiate the terms under which Orion would be willing to
manufacture and supply to GTX any dosage strengths or formulations of the
Product other than those that are available as an Orion Product as of the
Restatement Date (including without limitation any combination Product
containing Toremifene and another active ingredient) or any Product otherwise
having specifications different from Orion Product Specifications (such
Products, collectively "Other Product(s)"), as provided in this Section 17.4.

         The Parties shall conduct such discussions during a sixty (60) day
period following GTX's written request setting forth in sufficient detail the
changes proposed by GTX, or any mutually agreed extension of such time period
("Evaluation Period"). If Orion would be willing to manufacture such Other
Product, Orion shall within the Evaluation Period notify GTX of the terms and
conditions under which it would be willing to do so, and the Parties shall
negotiate a written amendment to this Agreement to include the applicable terms
and conditions under which Orion would manufacture and supply such Other
Product, including without limitation the supply price of such Other PRODUCT.
Upon execution of such amendment, such Other Product shall be deemed to be an
Orion Product. Such negotiation shall be conducted for up to one hundred twenty
(120) days following GTX's receipt of Orion's notice of such terms and
conditions ("Negotiation Period"). It is expressly agreed that Orion shall have
no obligation to manufacture and supply any Other Product unless a mutually
acceptable definitive written amendment to this Agreement, if any, in relation
to such Other Product is executed by duly authorized representatives of both
Parties.

         In the event Orion notifies GTX within the Evaluation Period that it
will not be interested in supplying such Other Product, or the Parties do not
amend this Agreement during the Negotiation Period to specify applicable terms
for, or execute another agreement governing, Orion's supply of such Other
Product for use in the Field (other than use in the Orion Field in the Orion
Territory), then if GTX has a good faith basis for requiring supply of such
Other Product, including but not limited to its desire to develop a dosage
strength of Product other than one which is in clinical development by or on
behalf of GTX as of the Restatement Date and in which an Orion Product is
available, or a formulation of Product that incorporates a new technology or
another active ingredient in order to optimize the pharmacokinetic properties of
Product, improve the competitive position of Product in the market, or to
increase the efficiency or safety of Products, GTX shall have the right to
manufacture, or engage a Third Party subcontractor to manufacture, such Other
Product for sale and use in the Field only. GTX shall exercise such right to
manufacture or have manufactured an Other Product for sale and use in the Field
(except for use in the Orion Field in the Orion Territory) pursuant to this
Section 17.4 in good faith only, and not for the purpose of obtaining the right
to manufacture Product by, for example, proposing minor changes to the Product
formulation that do not present a commercially reasonable basis for development.
To the extent reasonably necessary to implement such manufacturing right, Orion
hereby grants GTX a contingent license under Orion's Patent Rights, Orion
Know-How, Manufacturing Patents, and Product Manufacturing Know-How to make and


[ * ] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY
BRACKETS, HAS BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS
AMENDED.

                                       46.



have made the relevant Other Product for use in the Field in the GTX Territory
(except for use in the Orion Field in the Orion Territory). Such license shall
be exclusive and sublicensable but only for the purpose of having Products
manufactured for GTX, its Affiliates and Unaffiliated Sublicensees), and shall
become effective only under the circumstances specified in this Section 17.4.

18.      PRODUCT RECALLS

         18.1 RECALL NOTIFICATION. Each Party shall promptly notify the other
Party in writing of any facts relating to the advisability of the recall,
destruction or withholding from the market of the Product anywhere in the GTX
Territory (any of the foregoing, a "Recall").

         18.2 RECALL IMPLEMENTATION IN GTX TERRITORY. If at any time (A) any
governmental or regulatory authority in the GTX Territory issues a request,
directive or order for a Recall; (B) a court of competent jurisdiction orders a
Recall in the GTX Territory; or (C) GTX determines, following consultation with
Orion (except in emergency situations in which there is insufficient time for
such consultation), that a Recall in the GTX Territory is necessary or
advisable, GTX shall take all appropriate corrective actions to effect the
Recall and Orion shall provide GTX with such cooperation in connection with the
Recall as GTX may reasonably request.

         18.3 RECALL COSTS AND EXPENSES IN GTX TERRITORY. GTX shall bear the
costs and expenses of any Recall in the GTX Territory, provided that Orion shall
bear all costs and expenses of any Recall in the GTX Territory to the extent
such Recall is the result of a breach in the warranties set forth in Section
15.1.

19.      ADVERSE DRUG EXPERIENCES

         19.1 ADVERSE EVENTS AND SERIOUS ADVERSE EVENTS.

                       (A) To ensure that all relevant safety information for
Toremifene is shared between the Parties, the following information will be
exchanged: (i) GTX will provide to Orion all regulatory safety updates (e.g.
120-day safety updates, annual reports, and post-authorization safety updates)
concerning Product and information regarding all serious adverse events from
clinical studies and all spontaneous adverse reactions, including reports from
literature concerning the Product coming to the knowledge of GTX; and (ii) Orion
will provide to GTX Periodic Safety Update Reports prepared in accordance with
ICH E2C or equivalent guidelines as adopted by the European Medicines Evaluation
Agency (EMEA) relevant to Product for use in the Orion Field in the Orion
Territory, and information regarding all serious adverse events from clinical
studies and all spontaneous adverse reactions, including reports from literature
concerning Product, coming to the knowledge of Orion. All of the above mentioned
safety information shall be exchanged reasonably in advance of any applicable
regulatory deadlines or upon release of such information. In addition, any
safety information which may negatively affect the benefit-risk ratio of
Products or that may have consequences regarding the product information (e.g.
labeling, data sheets, instruction leaflets) or may require immediate safety
measures to be taken by either Party shall be forwarded to the other Party
without any delay. Each Party is responsible for any regulatory safety reporting
requirements

with respect to maintaining its own Regulatory Approval applications and
complying with regulatory requirements for Products that it has the right to
sell pursuant to this Agreement according to applicable laws, rules and
regulations.

                       (B) The intent of Section 19.1(a) is to enable each Party
to comply with regulatory requirements for Toremifene products, which
requirements may change from time to time. Concurrently with the execution of
this Agreement, the Parties shall execute an agreement setting forth a mutually
acceptable detailed procedure generally consistent with the intent of Section
19.1(a) that enables each Party to comply with such regulatory requirements with
respect to such Products. Under such agreement, from time to time after the
Restatement Date, the Parties shall meet upon request by either Party to discuss
and agree upon any modifications to such detailed procedure necessary to ensure
that each Party is in compliance with regulatory reporting requirements for
Products that it has the right to develop and sell pursuant to this Agreement.

         This Article 19 shall survive the expiration or termination of this
Agreement.

20.      REPRESENTATIONS AND WARRANTIES

         20.1 REPRESENTATIONS AND WARRANTIES OF THE PARTIES. Each Party hereby
represents and warrants to the other Party as follows:

a country-by-country basis for cause as described in this Section 21.2 as
follows:


[ * ] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY
BRACKETS, HAS BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS
AMENDED.

                                       49.


              21.2.1 BANKRUPTCY. Either Party shall have the right to terminate
this Agreement and same shall terminate upon expiry of a sixty (60) days notice
period, if the other Party becomes insolvent, is adjudged bankrupt, applies for
judicial or extra-judicial settlement with its creditors, makes an assignment
for the benefit of its creditors, voluntarily files for bankruptcy or has a
receiver or trustee (or the like) in bankruptcy appointed by reason of its
insolvency, or in the event an involuntary bankruptcy action has been omitted
and filed separately against the other Party and not dismissed within ninety

dissolution proceedings or otherwise discontinues business.

              21.2.2 MATERIAL BREACH. If either Party commits a material breach
of this Agreement and if the Party alleged to be in breach of this Agreement
fails to (i) cure such breach or (ii) commence bona fide dispute resolution
proceedings under Section 25.2 contesting whether a breach has occurred and/or
whether such breach is a material breach, in either case within sixty (60) days
after receipt of written notice from the Party asserting the breach, then the
Party asserting the breach may terminate this Agreement in its entirety (if such
breach is a material breach, other than as specified in Sections 6.4.2 and
12.11.1 or 12.11.2), or, if such breach is by GTX and is described in Section
6.4.2 or in Section 12.11.1, then Orion may terminate its supply obligations as
set forth under Article 14 and terminate the license granted to GTX pursuant to
Section 2.1, in each case with respect to the Major Country in relation to which
such material breach occurred under Section 6.4.2 or 12.11.1. If the Agreement
is terminated either in its entirety or with regard to a particular Major
Country, as the case may be, then if GTX is the breaching Party, GTX shall grant
to Orion a nonexclusive, royalty-bearing license, with the right to grant
sublicenses, under the GTX Patent Rights, the Trademarks, the Regulatory
Approvals (by means of assignment or transfer of, or authorization to
cross-reference, relevant Regulatory Approval(s)) and the GTX Know-How to make,
have made, develop, use, sell, offer for sale, market and promote, and import
Products in the country(ies) in which GTX's license terminates, or, if Orion is
the breaching Party, then the license granted to GTX shall be expanded to
include an exclusive, sublicensable license under the Orion Patent Rights, Orion
Know-How, and Manufacturing Patents to make and have made Products for use in
the Field in the GTX Territory, (except for use in the Orion Field in the Orion
Territory). In the event of termination of the Agreement due to Orion's breach,
Orion shall as soon as practically possible provide GTX with Product
Manufacturing Know-How to the extent reasonably necessary to enable GTX to
exercise its manufacturing right pursuant to this Section, including without
limitation providing up to ten (10) person-days of technology transfer
assistance at GTX's site of Manufacture or Product using Orion personnel skilled
in such manufacturing operations, at no charge to GTX.

                     (A) If the non-breaching Party obtains a license under this
Agreement as provided in Section 21.2.2, it shall pay to the other Party a
running royalty equal to [ * ] of Net Sales of Product by the non-breaching
Party, its Affiliates or Unaffiliated Sublicensees. Furthermore, if GTX is the
breaching Party, GTX shall promptly transfer to Orion, at GTX's expense, all
Regulatory Approvals and registration filings for the Product in the territory
in which Orion obtains such license, together with such documentation,
information and data in its possession as Orion may need for regulatory
compliance in the course of exercising its rights in such territory with respect
to Product.

         21.3 TERMINATION BY MUTUAL AGREEMENT. The Parties may terminate this
Agreement at any time by drafting and executing a mutually acceptable written
agreement. The written agreement shall specify the consequences of such
termination.

         21.4 TERMINATION BY GTX FOR SAFETY OR EFFICACY REASONS. If at any time
during the Term: (i) GTX decides not to file an application for Regulatory
Approval in any country or decides to withdraw such application due to
documented adverse reactions or other safety issues with the Product or the
Product's lack of efficacy or limited efficacy (collectively, "Safety or
Efficacy Issues"); (ii) GTX's application(s) for Regulatory Approval in any
country is rejected due to Safety or Efficacy Issues; (iii) GTX's application(s)
for Regulatory Approval in any country is subsequently withdrawn because of
Safety or Efficacy Issues; or (iv) the Product is withdrawn or recalled from the
market in any country because of Safety or Efficacy Issues, then GTX may, at its
option, terminate this Agreement with respect to such country upon thirty (30)
days prior written notice to Orion. GTX must exercise this right of termination
within the later of (a) sixty (60) days of the occurrence of the event giving
rise to such right or (b) thirty (30) days of GTX's last meeting, if any, with
the relevant regulatory authorities, provided that GTX uses reasonable diligence
to schedule such meeting and that Orion is providing reasonable co-operation to
GTX in connection with such meeting. GTX may, at its option, exercise its right
of termination under this Section 21.4 on a country-by-country basis, and, if
GTX does so, GTX's termination notice shall specify the country or countries of
the GTX Territory affected. GTX shall transfer to Orion, at Orion's expense, all
Regulatory Approvals and registration filings for the Product in the country for
which it terminates its license, together with such documentation, information
and data in its possession as Orion may need for regulatory compliance in the
course of any further development of Product in such country Orion may elect to
conduct thereafter.

         21.5 EFFECT OF TERMINATION. Termination or expiration of this Agreement
through any means and for any reason shall not relieve the Parties of any
obligations accruing prior thereto and shall be without prejudice to the rights
and remedies of either Party with respect to any prior breach of any of the
provisions of this Agreement.

23.      INTEGRATION

         This Agreement represents the entire Agreement between the Parties
relating to the subject matter hereof and supersedes all prior arrangements,
understandings, correspondence, notes, minutes and agreements between the
Parties (or their predecessors in interest) whether written or oral. No
supplement, modification or amendment of this Agreement shall be binding unless
executed by the Parties in writing and signed by the duly authorized
representatives of both Parties.

24.      ASSIGNMENT

         Neither Party may assign this Agreement or any of its rights hereunder,
nor delegate any of its duties or obligations hereunder, to any Third Party
without the prior written consent of the other Party, except (i) to an Affiliate
in accordance with the terms of this Agreement, in which case notification
thereof shall be provided to the other Party prior to such assignment to an
Affiliate, or (ii) in connection with a merger, consolidation or similar
reorganization. For clarity, this Agreement shall survive any such merger,
consolidation or reorganization of either Party with or into, another party and
no consent for such merger, consolidation or reorganization shall be needed.
Neither Party shall unreasonably withhold its consent (which shall be provided
promptly after a request is made) to any contemplated assignment if such
contemplated assignment is in connection with the sale by either Party of all or
substantially all of its assets to a Third Party. Any assignment of this
Agreement to an Affiliate of the assigning Party shall not relieve the assigning
Party of its responsibilities and obligations hereunder.

25.      GOVERNING LAW AND DISPUTE RESOLUTION

         25.1 GOVERNING LAW. This Agreement, including the validity,
construction, interpretation and performance thereof, shall be governed entirely

apply to this Agreement.

         25.2 DISPUTE RESOLUTION. All disputes arising out of or in connection
with this Agreement (except those involving actions commenced by or involving
Third Parties and affecting or involving only one of the Parties) shall be
resolved with the following mechanism:

              25.2.1 ATTEMPTED AMICABLE RESOLUTION. The Parties shall promptly
give each other written notice of any disputes requiring resolution hereunder,
which written notice shall specify the Section(s) of this Agreement the other
Party is alleged to have breached and shall briefly state the initiating Party's
claims, and the Parties shall use reasonable efforts to resolve any such
disputes in an amicable manner.

         Any disputes arising in connection with this Agreement which cannot be
resolved in an amicable manner by representatives of the Parties shall be
referred, not later than thirty (30) days after initiation of dispute resolution
proceedings under this Section 25.2.1, to the following corporate officers of
the Parties for resolution:

              25.2.2 ARBITRATION. Any disputes (excluding any dispute,

Arbitration Institute of the Stockholm Chamber of Commerce, Stockholm, Sweden in
accordance with said Rules then in effect with proceedings to be held in

submitted for resolution by a court of competent jurisdiction.

         25.3 EFFECT OF COMMENCING DISPUTE RESOLUTION. If either Party in good
faith commences dispute resolution proceedings under Section 25.2, (A) any
applicable notice periods or cure periods hereunder (including but not limited
to the periods referenced in Sections 21.2 and 21.4) shall be temporarily
suspended pending the outcome of such dispute resolution proceedings and (B) the
non-breaching Party may, at its option, pay any amounts payable to the other

other. Neither Party has any express or implied right or authority under this
Agreement to assume or create any obligations or make any warranties and
representations on behalf of or in the name of the other Party, or to bind the
other Party to any contract, agreement or undertaking with any Third Party, and
no conduct of the Parties pursuant to the terms of this Agreement shall be
deemed to establish such right or authority. Neither Party shall make any
representation to Third Parties that the relationship created hereby constitutes
a partnership, joint venture or agency relationship.

         The failure by either Party at any time to enforce any of the terms or
provisions or conditions of this Agreement or exercise any right hereunder shall
not constitute a waiver of the same or affect that Party's rights thereafter to
enforce or exercise the same. No waiver of any of the provisions of this
Agreement shall be deemed binding unless executed in writing by the Party to be
bound by it.

31.      HEADINGS
