            marketability of the Products or any distribution risk.

      (e)   Each time Patheon ships Products to Genelabs, it shall provide
            Genelabs, prior to such shipment, with a certificate of analysis
            that sets out the test results for each lot of Product, and which
            certifies that the Products shipped to Genelabs have been evaluated
            by Patheon's Quality Control/Quality Assurance department and that
            the Products comply with Genelabs Specifications and Patheon's
            Manufacturing Requirements. Further, Patheon shall, prior to such
            shipment, make available copies of all manufacturing related
            documentation, as defined in the Quality Agreement, associated with
            each Batch of Product produced, such documentation to be used by
            Genelabs to determine conformance of the Product to Genelabs
            Specifications and Patheon Manufacturing Requirements.

                                            *CONFIDENTIAL TREATMENT REQUESTED BY
                                                     GENELABS TECHNOLOGIES, INC.

      (f)   Notwithstanding anything set forth in this Agreement to the
            contrary, Patheon expressly understands and agrees that Genelabs
            shall have the sole and final authority to determine whether all
            or a portion of any Batch of Product is suitable for release and
            distribution.  In those instances where Genelabs has rejected a
            Batch which has otherwise, according to the provisions of Section
            2.5(b), been deemed suitable for use, Genelabs shall pay Patheon
            the Manufacturing Fee associated with that Batch.

2.5   REJECTION OF PRODUCTS.

      (a)   Genelabs shall inspect the Products manufactured by Patheon within
            thirty (30) days of the later of: (i) receipt of the Product; or
            (ii), receipt of the documentation defined in Section 2.4(e) and
            shall give Patheon written notice (a "DEFICIENCY NOTICE") of all
            claims for: (1) Products which deviate from Patheon Manufacturing
            Requirements; or (2) shortages in the amount of delivered Products,
            in each case prior to the expiry of such thirty (30) day period.
            Except as set out in Sections 4.3 and 4.4 below, Patheon shall have
            no liability for any deviations or shortages for which it has not
            received notice within such thirty (30) day period except, however,
            that such thirty (30) day notice period shall not apply to latent
            defects or any other such defects which are not reasonably
            discoverable by Genelabs within such thirty (30) day period.

      (b)   Upon receipt of a Deficiency Notice relating to claims under Section
            2.5(a)(1) above, Patheon shall have ten (10) days to notify Genelabs
            as to whether it agrees that the subject Product deviates from
            Patheon Manufacturing Requirements. If Patheon disagrees with the
            contents of such Deficiency Notice, it shall so advise Genelabs by
            notice in writing within ten (10) days after receipt of such
            Deficiency Notice. If Genelabs and Patheon fail to agree within ten
            (10) days after Patheon's notice to Genelabs as to whether any
            Products identified in the Deficiency Notice deviate from Patheon
            Manufacturing Requirements, the parties shall mutually select an
            independent third party to evaluate if the Products deviate from
            Patheon Manufacturing Requirements. If such evaluation certifies
            that any Products deviate from Patheon Manufacturing Requirements,
            Genelabs may reject those Products in the manner contemplated by
            Section 2.5(d). For the purposes of clarity, such third party
            determination of conformance of the Product to Patheon Manufacturing
            Requirements shall be solely for the purpose of determining whether
            the Manufacturing Fee for a given Batch or Batches, as applicable,
            shall be payable by Genelabs to Patheon. Regardless of the findings
            of any such third party, Genelabs shall nevertheless have the final
            authority to reject any Batch pursuant to Section 2.4(f). If the
            Product is found to deviate from the Patheon Manufacturing
            Requirements, Patheon shall pay for such third party evaluation. In
            all other such cases, the costs for such third party evaluation
            shall be paid by Genelabs.

                                            *CONFIDENTIAL TREATMENT REQUESTED BY
                                                     GENELABS TECHNOLOGIES, INC.

      (c)   Claims for shortages set out in a Deficiency Notice delivered to
            Patheon pursuant to Section 2.5(a)(2) shall be dealt with by Patheon
            either satisfying the shortage as soon as practicable but in no
            event later than within * days by the delivery of additional Product
            or, by the provision of an appropriate credit, at Genelabs'
            discretion.

      (d)   Subject to the provisions of Sections 2.5(a) and 2.5(b), Genelabs
            has the right to reject and return, at the expense of Patheon and
            for full credit, any portion of any shipment which deviates from
            Patheon Manufacturing Requirements, without invalidating the
            remainder of the order, to the extent that such deviation arises
            from Patheon's failure to manufacture the Products in accordance
            with the Patheon Manufacturing Requirements. All expenses incurred
            pursuant to this Section 2.5(d) must be reasonable and shall be only
            payable by Patheon after agreement by Patheon or, failing agreement,
            certification pursuant to Section 2.5(b) that the Products, or any
            rejected portion thereof, deviated from the Patheon Manufacturing
            Requirements.

      (e)   Where Genelabs has rejected all or a portion of a Batch or Batches
            of Product, as applicable, pursuant to Section 2.5(d), Patheon shall
            refund to Genelabs the cost of the Active Materials for such Product
            in an amount equal to *. In addition, if Genelabs has previously
            paid the Manufacturing Fee for Product which is ultimately rejected
            pursuant to Section 2.5(d), Patheon shall refund such Manufacturing
            Fee associated with the rejected Product. Where the rejected Product
            represents a portion of a Batch, the refund shall be proportionately
            based. Where Genelabs has not previously paid the Manufacturing Fee
            associated with the rejected Product, Patheon shall not invoice
            Genelabs for such Manufacturing Fee.

      (f)   Rejection of * or more Batches of Product in any one Year due to the
            failure by Patheon to manufacture Product in accordance with the
            Patheon Manufacturing Requirements shall be considered a material
            breach of this Agreement and Genelabs may, at its option, terminate
            this Agreement.

2.6 STABILITY TESTING. Patheon shall conduct stability testing on the Products
in accordance with the protocols submitted by Genelabs, the particulars of which
form part of the annexed Schedule E, and for the fees to be mutually agreed upon
between the parties. Patheon shall not make any changes to these testing
protocols without prior written approval from Genelabs. In the event that any
lot of Products fails stability testing, Patheon and Genelabs shall jointly
determine the proceedings and methods to be undertaken to investigate the causes
of such failure, including which party shall bear the cost of such
investigation, provided that Patheon shall not be liable for any such costs
unless there has been a breach by it of the Patheon Manufacturing Requirements.
Further, Genelabs shall have the final authority to determine what actions, if
any, shall be taken due to a stability failure. Patheon will provide any and all
data and results relating to the stability testing upon request by Genelabs.
From time to time, Patheon shall, at the request of Genelabs, also provide
stability testing services with respect to products not


                                       7

                                            *CONFIDENTIAL TREATMENT REQUESTED BY
                                                     GENELABS TECHNOLOGIES, INC.

manufactured by Patheon, the cost of such services to be agreed to between the
parties in writing prior to such services being undertaken. For stability
studies contemplated under this Section 2.6, Patheon shall supply data to
Genelabs within thirty (30) days following completion of testing.

                                    ARTICLE 3

                     ORDERS, DELIVERY, INVOICING AND PAYMENT

3.1 MARKET OUTLOOK. Genelabs acknowledges that for optimal production planning,
Patheon requires an understanding of Genelabs' strategic vision for the Products
in the market and agrees, to the extent that Genelabs has such information
(including, if any, Genelabs' ten (10) year market outlook studies), to share
such information with Patheon, provided that any information so provided shall
be subject to the confidentiality provisions of Article 8, and further provided
that Patheon agrees that any such information shall not constitute a binding
commitment of any kind on the part of Genelabs.

3.2 ORDERS AND FORECASTS. Genelabs shall provide Patheon with the following:

      (a)   concurrent with the execution of this Agreement, a written
            non-binding twelve (12) month forecast of the volume of each Product
            that Genelabs then anticipates will be required to be produced and
            delivered to Genelabs during that twelve (12) month period. Such
            forecast will be updated by Genelabs quarterly on a rolling basis
            and updated forthwith upon Genelabs determining that the volumes for
            the first quarter contemplated in the most recent of such forecasts
            has changed by more than * per cent (*%); and

      (b)   firm written orders ("FIRM ORDERS") will be submitted by Genelabs on
            or before the 20th day of a calendar month for the Products to be
            delivered to Genelabs on a date not less than ninety (90) days from
            the first day of the calendar month immediately following the date
            that the Firm Order is submitted.

3.3 WRITTEN ORDERS. The Firm Orders submitted to Patheon pursuant to Section
3.2(b) shall specify Genelabs' purchase order number, quantities by Product type
and monthly delivery schedule necessary to ensure the timely production and
delivery of the Products. The quantities of Products ordered in such written
orders shall be firm and binding on Genelabs and shall not be subject to
reduction. Patheon agrees that Firm Orders submitted by Genelabs pursuant to
Sections 3.2(b) and this Section 3.3 must be accepted by Patheon for manufacture
if they are not more than * percent (*%) of the amount most recently forecast
for that period. Patheon will use commercially reasonable efforts to manufacture
any amounts beyond that. Firm Orders not rejected by Patheon within three (3)
business days of receipt by Patheon shall be deemed to have been accepted by
Patheon. Should there be a conflict between this Agreement and the terms
contained in any Genelabs purchase order, this Agreement shall take precedence,
to the extent the terms conflict.


                                       8

                                            *CONFIDENTIAL TREATMENT REQUESTED BY
                                                     GENELABS TECHNOLOGIES, INC.

3.4 RELIANCE BY PATHEON. Genelabs understands and acknowledges that Patheon will
rely on the Firm Orders submitted pursuant to Section 3.2(b) in ordering the
Components required to meet such Firm Orders. Genelabs shall reimburse Patheon
for the cost of any Components purchased in support of Firm Orders which,
because of termination pursuant to Section 3.6, cannot be consumed by Patheon
during the three (3) month period following termination provided that Patheon
shall use commercially reasonable efforts to use these Components for other
customers of Patheon. Patheon may, at its sole discretion, purchase Components
in support of production beyond the Firm Order portion of the forecast. However,
Patheon expressly agrees and understands that such purchase shall be at
Patheon's sole risk and Genelabs shall not be liable for the cost of these
Components should they become unusable due to subsequent reductions in forecast
purchases or termination by Genelabs unless Genelabs consents in writing to such
purchase prior to Patheon making a purchase commitment.

3.5 MINIMUM ORDERS. The Products to be manufactured and packaged by Patheon may
only be ordered in at least the Minimum Run quantities set out in Schedule C.
For clarity, this means that in no event shall an order placed by Genelabs be
for quantities less than two (2), three (3), or one-half (1/2) Batches for the
1,000, 120, and 12-count presentations, respectively. Where Genelabs has placed
an order for one-half (1/2) Batch of the 12-count presentation, both parties
understand and agree that such order shall be supplied from capsules produced to
fill another presentation (i.e., sub-lotting a portion of capsules from an order
for another presentation). Thus, in the event that Genelabs places an order for
one-half (1/2) Batch of the 12-count, completion of such order shall be tied to
the manufacture date for the next order of either the 120-count or the
1,000-count presentation. For orders that fall between two Minimum Run
quantities, Patheon shall determine at its sole discretion how to schedule the
order; however, in all cases, the pricing applied to purchase orders from
Genelabs shall be set based on the Yearly volume requirements pursuant to
Section 3.2(a) and subject to adjustment, as defined in Section 9.5.

3.6 TERMINATION. If this Agreement expires or is terminated in whole or in part
for any reason other than a default by Patheon, in addition to any other
remedies that either Party may have in the event of default:

      (a)   Genelabs shall purchase, at Patheon's acquisition cost (as supported
            by appropriate receipts) plus a * percent (*%) handling fee, the
            Components applicable to the Products which were purchased, produced
            or maintained by Patheon in contemplation of filling Firm Orders or
            in accordance with Section 3.4 prior to notice of termination being
            given;

      (b)   Genelabs shall purchase all undelivered Products which were
            manufactured and/or packaged pursuant to a Firm Order, at the price
            in effect at the time the Firm Order was placed;

      (c)   Genelabs shall pay Patheon's suppliers or reimburse Patheon, as
            applicable, for the purchase price payable pursuant to Patheon's
            orders with suppliers of Components, provided such orders were made
            by


                                       9

                                            *CONFIDENTIAL TREATMENT REQUESTED BY
                                                     GENELABS TECHNOLOGIES, INC.

            Patheon in reliance on Firm Orders in accordance with Section 3.4 in
            cases where Genelabs has agreed in advance to such purchases and
            provided Genelabs is permitted to take delivery of such Components;
            and

      (d)   Patheon shall, in a timely manner, but in no event more than ninety
            (90) days from the date of termination, convert any work in process
            that may exist in support of Firm Orders to Product for purchase by
            Genelabs. Should Patheon fail to complete such conversion, Patheon
            shall reimburse Genelabs for * represented by such work in process.

If this Agreement is terminated as a result of a default by Patheon, Genelabs
agrees to purchase such of the items referred to in Sections 3.6 (a), (b) and
(c) above as it determines, acting reasonably, can be used by it.

3.7 PACKAGING AND RAW MATERIALS. All Components shall be purchased (with the
exception of those which are supplied by Genelabs) and tested by Patheon at
Patheon's expense in accordance with Patheon Manufacturing Requirements.
Amendments to Genelabs Specifications requested by Genelabs will only be
implemented with the approval of Patheon following a technical and cost review,
such approval not to be unreasonably withheld but being subject to Genelabs and
Patheon reaching agreement as to price revisions as specified in Section 3.8
necessitated by any such amendment.

3.8   CHANGE IN GENELABS SPECIFICATIONS.

      (a)   If Genelabs requests a change in Genelabs Specifications which would
            result in an increase in Patheon's costs for Components or for
            manufacturing the Products, the parties shall discuss what impact,
            if any, such change will have on the price of the Products. If
            Genelabs should accept a proposed price change, the proposed change
            in Genelabs Specifications shall be implemented, and the price
            change shall become effective only with respect to those orders of
            Products which are manufactured in accordance with the revised
            Genelabs Specifications. Similarly, if Genelabs requests a change in
            Genelabs Specifications which would result in a decrease in
            Patheon's costs for components or for manufacturing the Products,
            the parties will work together to develop a mutually agreeable
            reduced cost for services from Patheon for Genelabs. Notwithstanding
            the foregoing, all changes to Genelabs Specifications shall, prior
            to implementation, be approved in writing by both parties hereto.

      (b)   Notwithstanding any change in Genelabs Specifications implemented
            in accordance with the terms of Section 3.8 (a) above, Genelabs
            agrees to purchase all Products manufactured by Patheon, subject
            to the provisions of Section 2.5, based upon any "old" Genelabs
            Specifications at the "old" price for those Products provided
            that such Products were produced based on Firm Orders received
            from Genelabs.  In addition, Genelabs agrees to purchase, at
            Patheon's cost (subject to the limits of Section 3.4), all


                                       10

                                            *CONFIDENTIAL TREATMENT REQUESTED BY
                                                     GENELABS TECHNOLOGIES, INC.

            Inventory utilized under the "old" Genelabs Specifications and
            purchased or maintained by Patheon in order to fill Firm Orders
            or in accordance with Section 3.4, to the extent that such
            Inventory can no longer be utilized under the revised Genelabs
            Specifications, in accordance with the terms of this Agreement.
            Open purchase orders for Components no longer required under any
            revised Genelabs Specifications which were placed by Patheon with
            suppliers in order to fill Firm Orders or in accordance with
            Section 3.4 shall be cancelled where possible, and where such
            orders are not subject to cancellation without penalty, shall be
            assigned to and satisfied by Genelabs.

3.9 SHIPMENTS. Deliveries of Products shall be made Free Carrier ("FCA"), as
such term is defined in the INCOTERMS 2000, Patheon's shipping point. Such title
as Patheon has in Products and risk of loss or of damage to Products shall
remain with Patheon until Products are delivered to the carrier by Patheon for
shipment at the FCA point at which time title and risk of loss or damage shall
transfer to Genelabs. Patheon shall, in accordance with Genelabs' instructions,
(i) arrange for shipping and insurance, to be paid by Genelabs and (ii) at
Genelabs' risk and expense, obtain any export licence or other official
authorisation and carry out all customs formalities necessary to export the
Products. Genelabs may select the freight carrier used by Patheon to ship
Products and may monitor Patheon's shipping and freight practices as they
pertain to this Agreement. Transport conditions shall be based upon Genelabs
Specifications for the transportation of the Products.

3.10 INVOICES AND PAYMENT. Except as otherwise provided in this Agreement,
Patheon shall charge Genelabs for only those Products that are shipped to
Genelabs pursuant to Firm Orders and which conform to the Patheon Manufacturing
Requirements, and shall submit to Genelabs, with each shipment of Products, an
invoice covering such shipment. Each such invoice shall, to the extent
applicable, identify Genelabs' purchase order number, Product numbers, names and
quantities, unit price, freight charges and the total amount to be remitted by
Genelabs. Genelabs shall pay all such invoices within thirty (30) days of the
later of: (i) shipment of the Product by Patheon; or (ii) receipt of the
documentation referred to in Section 2.4(e). In no event may Patheon either ship
to or invoice Genelabs for any Product which has not been fully completed and
has not passed all testing as specified under Patheon Manufacturing
Requirements. Genelabs may, at its sole discretion, approve the shipment of
Product prior to the completion of required testing and Patheon release.
However, nothing in this Agreement shall be construed as requiring Genelabs to
provide such approval. Further, approval by Genelabs to ship a given Batch or
Batches of Product prior to completion of testing shall have no bearing
whatsoever on Genelabs' later refusal to do the same with a future Batch or
Batches.

3.11 CAPITAL EQUIPMENT. Both parties agree and understand that in the case of
capital equipment purchased by Genelabs, whether purchased directly by Genelabs
and delivered to Patheon or, purchased by Patheon with reimbursement of the
purchase cost to Patheon by Genelabs, title to and interest in all such capital
equipment shall at all times be in Genelabs. At present, both parties anticipate
that this will include the purchase of change parts commonly known as chutes and
slats, the cost of which shall not exceed $*, the


                                       11

                                            *CONFIDENTIAL TREATMENT REQUESTED BY
                                                     GENELABS TECHNOLOGIES, INC.

prior purchase of change parts (i.e., *) for Patheon's * encapsulator and
unscrambler change parts (see Schedule C for detail). Further, Patheon warrants
that based on the most recent forecast provided to Patheon with the execution of
this Agreement, Patheon has sufficient vault space to store the Active Material
required to produce the Product (the Active Material being a controlled
substance in Canada, secure storage in an access-controlled vault is required by
Canadian law) and further, that should expansion of this vault be required to
handle production of Yearly Product quantities substantially in excess of this
forecast (substantially in this case being defined as volumes greater than *%
above the total of the Annual Quantity in units of all three presentations in
the Volume 5 tier set forth in Schedule C), that in no event shall the cost to
Genelabs for all such vault expansions exceed a total of $*.

3.12 LOT NUMBERING/EXPIRATION DATES. Patheon shall make arrangements for and
implement the imprinting of lot numbers and expiration dates for each Product
shipped. Such expiration dates shall be based on Genelabs Specifications and
shall be affixed on the Products and on the shipping carton of each product as
is required by cGMPs. The system used by Patheon for lot numbering and
expiration dates is detailed in Schedule F hereto.

                                    ARTICLE 4

                                  CO-OPERATION

4.1 QUARTERLY REVIEW. Each party shall forthwith upon execution of this
Agreement appoint one of its employees or consultants to be a relationship
manager responsible for liaison between the parties. The relationship managers
shall meet not less than quarterly, either in person, via teleconference, or via
videoconference, to review the current status of the business relationship and
manage any issues that have arisen.

4.2 RECORDS AND ACCOUNTING BY PATHEON. Patheon shall keep records of the
manufacture, testing and shipping of the Products, and retain samples of such
Products as are necessary to comply with the Patheon Manufacturing Requirements
applicable to Patheon, the requirements specified under 21 CFR parts 210-211, as
well as to assist with resolving product complaints and other similar
investigations. Copies of such records and samples shall be made available to
Genelabs upon its request and shall be retained by Patheon and be available to
Genelabs for a period of five (5) years following the date of manufacture, or
longer if required by law or regulation. Patheon shall, prior to discarding any
documentation related to the manufacture of Genelabs' Products, make such
documentation available for collection by Genelabs at Genelabs' expense. Patheon

applicable to Genelabs.

4.3 PRODUCT RECALLS.

      (a)   Patheon and Genelabs shall each maintain records as may be
            necessary to permit a recall or a field correction of any
            Products delivered to Genelabs


                                       12

            or customers of Genelabs, effected voluntarily or under a threat of,
            or a directive by, any governmental agency. Each party shall give
            immediate notice by telephone (to be confirmed in writing) to the
            Director of Quality Control/Quality Assurance of the other party
            upon discovery that any Products should be recalled or corrected, or
            may be required to be recalled or corrected, and each party upon
            receiving any such notice or upon any such discovery, shall cease
            and desist from further shipments of such Products in its possession
            or control until a decision has been made whether a recall or some
            other corrective action is necessary. The decision to initiate a
            recall or to take some other corrective action, if any, shall be
            made and implemented by Genelabs. Patheon will cooperate as
            reasonably required by Genelabs, in accordance with all applicable

            such plan shall be subject to prior consultation, which consultation
            shall not unreasonably delay such plan.

      (b)   To the extent that a recall results from, or arises out of, any
            breach by Patheon of the Patheon Manufacturing Requirements, (i)
            such recall shall be made at Patheon's cost and expense, and (ii)
            Patheon shall use its best efforts to replace the recalled Products
            with new Products within sixty (60) days from the date that Genelabs
            notifies Patheon about the recalled Products, contingent upon the
            receipt by Patheon from Genelabs of all required Active Materials.
            Patheon's cost for such Active Materials shall be limited to *. In
            the event that: (1) Patheon is unable to replace the recalled
            Products within this sixty (60) day period (except where such
            inability results from a failure to receive the required Active
            Materials); or (2) such new Products are also recalled or returned
            due to a breach by Patheon of the Patheon Manufacturing
            Requirements, then Patheon shall reimburse Genelabs for the
            Manufacturing Fee that Genelabs paid Patheon for the affected
            Products. In all other circumstances, recalls or other corrective
            actions shall be made at Genelabs' cost and expense.

4.4 PRODUCT RETURNS. Genelabs shall have the responsibility for handling
customer returns of the Products. Patheon shall provide Genelabs with such
assistance as Genelabs may reasonably need to handle such returns. To the extent
that such return results from, or arises out of, any breach by Patheon of the
Patheon Manufacturing Requirements, Patheon shall use all reasonable efforts to
replace the returned Products with new Products within sixty (60) days from the
date that Genelabs notifies Patheon about the returned Products, contingent upon
the receipt by Patheon from Genelabs of all Active Materials. Patheon's cost for
such Active Materials shall be limited to *. In the event that: (i) Patheon is
unable to replace the returned Products within this sixty (60) day period
(except where such inability results from a failure to receive the required
Active Materials); or (ii) such new Products are also returned or recalled due
to a breach by Patheon, then Patheon shall reimburse Genelabs for * that
Genelabs paid Patheon for the affected Products. In all other circumstances,
customer returns or similar actions shall be made at Genelabs' cost and expense.

4.5 GOVERNMENTAL AGENCIES. Each party may communicate with any governmental
agency, including but not limited to governmental agencies responsible for
granting regulatory approval for the Products, regarding such Products if, in
the opinion of that party's counsel, such communication is necessary to comply
with the terms of this Agreement or the requirements of any law, governmental
order or regulation, provided, however, that, unless in the reasonable opinion
of its counsel there is a legal prohibition against doing so, such party shall
permit the other party to accompany and take part in relevant communications
with the agency, and to receive copies of all such communications from the
agency.

4.6 CUSTOMER QUESTIONS AND COMPLAINTS. Genelabs shall have the sole
responsibility for responding to questions and complaints from Genelabs'
customers. Questions or complaints received by Patheon from Genelabs' customers
shall be promptly referred to Genelabs. Patheon shall cooperate as reasonably
required to allow Genelabs to determine the cause of and resolve any customer
questions and complaints. Such assistance shall include follow-up
investigations, including testing. In addition, within ten (10) days from the
date of request, Patheon shall provide Genelabs with all necessary information
that will enable Genelabs to respond properly to questions or complaints
relating to the Products. Unless it is determined that the cause of any customer
complaint resulted from a breach by Patheon of the Patheon Manufacturing
Requirements, all reasonable costs incurred by Patheon in respect of this
Section 4.6 shall be borne by Genelabs. In the event that such complaint
resulted from the breach by Patheon of the Patheon Manufacturing Requirements,
all reasonable costs in respect of this Section 4.6 shall be borne by Patheon.

                                                     GENELABS TECHNOLOGIES, INC.

      (a)   Upon failure of either party to remedy its material breach of any of
            the obligations or provisions of this Agreement within sixty (60)
            days following receipt of written notice of said breach, the
            aggrieved party shall have the right to terminate this Agreement
            immediately by written notice.

      (b)   Either party at its sole option may immediately terminate this
            Agreement upon written notice, but without prior advance notice, to
            the other party in the event that: (i) the other party is declared
            insolvent or bankrupt by a court of competent jurisdiction; (ii) a
            voluntary petition of bankruptcy is filed in any court of competent
            jurisdiction by such other party; or (iii) this Agreement is
            assigned by such other party for the benefit of creditors.

      (c)   Genelabs may terminate this Agreement as to any Product upon thirty
            (30) days written notice to Patheon in the event that any
            governmental agency takes any action, or raises any objection, that
            prevents Genelabs from importing, exporting, purchasing or selling
            such Product.

      (d)   Any termination or expiration of this Agreement shall not affect any
            outstanding obligations or payments due hereunder prior to such

            that the parties may have under this Agreement.

      (e)   Patheon may terminate this Agreement on six (6) months prior written
            notice if Genelabs assigns, pursuant to Section 11.9, any of its
            rights under this Agreement to an assignee that is, in the opinion
            of Patheon acting reasonably, not a creditworthy substitute for
            Genelabs, is a competitor of Patheon or with whom Patheon has had
            prior unsatisfactory business relations. Should Patheon decide to
            terminate this Agreement in accordance with this Section 5.4(e),
            Patheon will continue to supply the assignee with Product until the
            earlier of: (i) *; and (ii) * from the date of termination. In such
            circumstances, Genelabs shall continue to be responsible for the
            obligations of the assignee during the transition period.

5.5 PRODUCT DISCONTINUATION. During the Initial Term of this Agreement or any
extension thereof, Genelabs shall provide at least six (6) months advance notice

Genelabs to discontinue sale of the Product. This requirement shall not apply to
any involuntary discontinuation resulting from withdrawal of approval for sale
by a regulatory agency, pursuant to Section 5.4(c).

                                       17

                                      PRICE

9.1 PRICE. The prices for the Products listed in Schedule C are intended by the
parties to be a guaranteed price for the Fixed Price Period, subject to the
amendments to such prices provided for in this Article 9. The prices for any
Products delivered pursuant to the terms of this Agreement during any period
following the Fixed Price Period shall be determined in accordance with Section
9.3.

9.2 PRICE ADJUSTMENTS. During any Year of this Agreement, the prices set out in
Schedule C shall be subject to adjustment in accordance with the following:

      (a)   if at any time and from time to time, but no more frequently than
            once per Year, Patheon determines, acting reasonably and based on
            the forecasts and Firm Orders received from Genelabs, that the
            then-current yearly run-rate volumes (including, without limitation,
            any permanent reductions in volumes) relating to a specific Product
            will constitute no more than eighty-five percent (85%) of the
            forecasted yearly volumes for that Product for that same Year,
            Patheon may request an adjustment to the price of that Product to
            reflect the increased Component costs that Patheon will incur as a
            result of the reduced volumes. In connection with such request,
            Patheon shall deliver to Genelabs a revised Schedule C setting out
            the adjusted Component costs that will be incurred based on the
            then-anticipated volumes for the relevant Product, together with
            documentation which supports the basis for Patheon's increased
            costs. Upon delivery of such a request, each of Genelabs and Patheon
            shall forthwith use all reasonable efforts to agree on a revised
            price for the relevant Product that reflects the increased Component
            costs being incurred by Patheon;

      (b)   if at any time extraordinary market conditions result in
            Patheon's cost of Components being greater than normal forecasted
            increases, Patheon may


                                       18

                                            *CONFIDENTIAL TREATMENT REQUESTED BY
                                                     GENELABS TECHNOLOGIES, INC.

            request an adjustment to the price of any affected Product to
            compensate it for such increased Component costs, but not more than
            once per Year. For the purposes of this Section 9.2(b), changes
            greater than normal forecasted increases shall be considered to have
            occurred if (i) the cost of a Component is more than *% greater than
            the cost for such Component that the price quote was based upon or
            (ii) the aggregate cost for all Components required to manufacture a
            Product is more than *% of the total Component costs for such
            Product that the price quote was based upon. To the extent Product
            prices have been previously adjusted pursuant to this Section 9.2(b)
            to reflect an increase in the cost of one or more Components, the
            adjustments provided for in (i) and (ii) above shall operate based
            on the costs attributed to such Component (or Components) at the
            time the last of such adjustments were made. In connection with a
            price adjustment request pursuant to this Section 9.2(b), Patheon
            shall deliver to Genelabs a revised Schedule C setting out the
            adjusted Component costs that will be incurred as a result of the
            greater than normal forecasted increases, together with supporting
            documentation which details the basis for Patheon's increased costs.
            Upon delivery of such a request, each of Genelabs and Patheon shall
            forthwith use all reasonable efforts to agree on a revised price for
            each affected Product that reflects the increased Component costs
            being incurred by Patheon;

      (c)   Beginning on January 1, 2006, on each Yearly anniversary of this
            Agreement, following the Fixed Price Period, Patheon shall be
            entitled to request an adjustment to the price charged in respect
            of direct labour, overhead and manufacturing fees based on the
            Industrial Product Price Index, Pharmaceuticals, No. V157093 and
            in direct labour, overheads and manufacturing fees based on the
            increases in the Consumer Price Index, Drug & Pharmaceuticals,
            published by Statistics Canada during the immediately prior Year.

9.3 PRICING AFTER FIXED PRICE PERIOD. The prices for each Product during each
additional Year beyond the Fixed Price Period that this Agreement remains in
force shall be agreed to between the parties prior to the commencement of each
such Year. Genelabs shall provide Patheon with the yearly volume forecasts
contemplated by Section 3.2(a) at least ninety (90) days prior to the first day
of each such additional Year. Based on those projections, Patheon will deliver
to Genelabs, no later than thirty (30) days after receipt of such yearly
forecast, a revised Schedule C and such other budgetary pricing information as
it deems necessary to allow the parties to effectively settle all prices for the
subsequent Year. Thereafter, the parties shall use all reasonable efforts to
come to agreement with respect to the applicable price for each Product during
the relevant Year, based on the anticipated changes in Product volumes,
Component costs and other relevant market conditions. Such revised prices shall
become effective as of the first day of the subject Year.

9.4 PRICING BASIS. The price applied to any purchase order and paid by Genelabs
for Product in any Year is quoted based upon the estimated annual volume per
Product


                                       19

                                            *CONFIDENTIAL TREATMENT REQUESTED BY
                                                     GENELABS TECHNOLOGIES, INC.

specified in Schedule C or thereafter specified in the forecast provided
pursuant to Section 3.2(a) for the Year and is subject to change, as specified
herein, if the specified Minimum Run quantity and estimated annual volume is not
met.

9.5 VOLUME PRICE RECALCULATIONS. In each Year, Patheon shall charge Genelabs for
the manufacturing services at the rates set forth in the attached Schedule C,
based on the total amount of Product expected to be ordered as set forth in the
12-month rolling forecast (or fraction of such 12 month rolling forecast, as
applicable) for such Year.

      (a)   If at any time during the Year, Genelabs has ordered a sufficient
            volume of Product for any given packaging presentation to qualify
            for the next lower-priced volume tier, the price applied to purchase
            orders from Genelabs for Product(s) for all subsequent orders for
            the balance of the Year shall reflect this next lower-priced tier.

      (b)   At the end of each Year, both parties will perform a review of the
            actual quantities of Product (by presentation) requested through
            Firm Orders during that Year by Genelabs to determine if sufficient
            Product was ordered to achieve the volume pricing requirements
            applied throughout the Year.

      (c)   If the amount of each Product presentation ordered has exceeded the
            volume tier pricing that was applied to Genelabs' purchase orders
            (and related payments) during the Year, then within thirty (30) days
            after the end of the relevant Year, Patheon shall refund Genelabs
            the difference between the amount Genelabs has paid for such Product
            and the amount that Genelabs should have paid based on total
            purchases.

      (d)   If the amount of each Product presentation ordered has not met the
            volume tier pricing that was applied to Genelabs' purchase orders
            (and related payments) during the Year, then within thirty (30) days
            after the end of the relevant Year, Patheon shall invoice Genelabs
            for the difference, if any, between the amount Genelabs should have
            paid for total purchases and the amount that Genelabs actually paid.

9.6 ADJUSTMENT TO ACTIVE MATERIALS VALUE. Prior to the end of each Year, the
parties shall determine a revised Active Materials Value as reflected in
Schedule G to be applied to the following Year, to account for changes in the
cost of the Active Materials, and as supported by appropriate documentation from
Genelabs. The parties will agree to the revised Active Materials Value and amend
Schedule G accordingly. In no event shall the Active Materials Value be adjusted
more than once per Year.

9.7 MANUFACTURING COSTS. Notwithstanding anything in this Agreement to the
contrary, in no event shall the price increase contemplated by Patheon exceed
the lesser of either: (a) the percentage increase in the Components based on the
Industrial Product Price Index, Pharmaceuticals, No. V157093 and in direct
labour, overheads and manufacturing fees based on the Consumer Price Index, Drug
& Pharmaceuticals,

published by Statistics Canada during the immediately prior Year; or (b), the
aggregate increase in Patheon's direct labour, overheads and manufacturing fees
and Component costs as demonstrated by supporting documentation from Patheon and
its Component suppliers. Patheon shall manufacture Product using Option B in
Schedule C (i.e., the * encapsulator) unless otherwise approved in writing by
Genelabs, which approval shall not be unreasonably withheld.

9.8 MULTI-COUNTRY PRICING. The pricing set forth in Schedule C of this Agreement
as of the Effective Date is for Product intended for sale and distribution in
the United States of America. If Genelabs decides that it wishes to have Patheon
manufacture the Product for countries in addition to the United States of
America, then Genelabs shall inform Patheon of the packaging requirements needed
for this new country market and Patheon shall prepare a quotation for
consideration by Genelabs of the additional Component costs, if any, packaging
fees and the change over fees for the Product destined for the new country
market. The agreed additional packaging requirements and related packaging costs
and change over fees shall be set out in a written amendment to this Agreement.

notify Genelabs of any inspections by any governmental agency directly or
indirectly involving the Products. Where such governmental agency inspections
have been arranged for in advance, Patheon shall notify Genelabs, to the extent
possible, not less than, seventy-two (72) hours prior to such inspections and
Genelabs shall have the right to be present during such inspections. In those
instances where such governmental agency inspections are performed on an
unannounced basis, Patheon shall inform Genelabs as specified in the Quality
Agreement. In those instances where Patheon is subject to negative regulatory
action from a governmental agency that may directly or indirectly impact the
Products, Genelabs shall have the right to audit Patheon's operations to assess

and with all applicable laws and regulations.

11.5 REPORTS. Patheon will supply, on an annual calendar basis, product data,
including release test results, complaint test results, all investigations (in

with the FDA, TPD, EMEA, or similar European regulatory authority. Further,
Patheon shall provide to Genelabs on a quarterly basis, a report detailing the
amounts of Product produced in the quarter, as well as all work in process
related to ongoing production. The report shall detail, among other things, the
yield rate for each Batch produced as well as the overall yield rate experienced
by Patheon during the report quarter. Patheon shall reimburse to Genelabs no
later than thirty (30) days following the end of a Year at * an amount equal to
any * represented by a yield loss for that Year in excess of a yield rate to be
mutually agreed upon between the parties following completion of the first ten
(10) commercial Batches. In regard to this yield rate, a per Batch yield rate
shall be established and such agreed upon yield rate shall be appended to the
Quality Agreement.

11.6 INSURANCE. Each party shall maintain comprehensive general liability
insurance, including blanket contractual liability insurance covering the
obligations of that party under this Agreement through the term of this
Agreement and for five (5) years thereafter, which insurance shall afford limits
as mutually agreed between the parties from time to time for each occurrence for
bodily injury liability, personal injury liability, products liability, property
damage liability, contractual liability and completed operations liability. Each
party will provide the other with a certificate of insurance evidencing the
above and showing the name of the issuing company, the policy number, the

certificate shall further provide for a minimum of thirty (30) days written
notice to the recipient of a cancellation of, or material change in, the
insurance.

Agreement shall not be construed to create between Patheon and Genelabs any

principal-agent, joint-venturer, co-partners or any similar relationship, the
existence of which is expressly denied by the parties hereto.

11.8 NO WAIVER. Either party's failure to require the other party to comply with
any provision of this Agreement shall not be deemed a waiver of such provision

obligations hereunder except with the written consent of Genelabs, such consent

however, that Genelabs shall give prior written notice of any assignment to
Patheon. Any assignee shall covenant in writing with Patheon to be bound by the

otherwise agreed by Patheon. Notwithstanding the foregoing provisions of this
Section 11.9, either party may assign this Agreement to any of its Affiliates or
to a successor to or purchaser of all or substantially all of its business,
provided that such assignee executes an agreement with the non-assigning party
hereto whereby it agrees to be bound hereunder.

11.10 FORCE MAJEURE. Neither party shall be liable for the failure to perform
its obligations under this Agreement if such failure is occasioned by a cause or
contingency beyond such party's reasonable control, including, but not limited
to, strikes or other labour disturbances, lockouts, riots, wars, fires, floods,
storms, interruption of or delay in transportation, or compliance with any order
or regulation of any government entity acting within colour of right. A party
claiming a right to excused performance under this Section 11.10 shall
immediately notify the other party in writing of the extent of its inability to
perform, which notice shall specify the occurrence beyond its reasonable control
that prevents such performance, as well as its estimate as to when remedy of the
causes of force majeure may be reasonably expected to occur.
