2.3  ACTIVE MATERIAL YIELD.

     (a) Reporting. Patheon shall provide the Client with a quarterly inventory
report of the Active Material held by Patheon in accordance with the inventory
report form annexed hereto as Schedule H, which shall contain the following
information for such quarter:

     QUANTITY RECEIVED: The total quantity of Active Material that complies with
     the Specifications and is received at a Manufacturing Site during the
     applicable period.

     QUANTITY DISPENSED: The total quantity of Active Material dispensed at a
     Manufacturing Site during the applicable period. The Quantity Dispensed is
     calculated by adding the Quantity Received to the inventory of Active
     Material that complies with the Specifications and is held at the beginning
     of the applicable period, less the inventory of Active Material that
     complies with the Specifications and is held at the end of such period. The
     Quantity Dispensed shall only include Active Material received and
     dispensed in connection with commercial manufacturing of Products and, for
     certainty, shall not include any Active Material received or dispensed in
     connection with technical transfer activities or development activities
     during the applicable period, including, without limitation, any
     regulatory, stability, validation or test batches manufactured during the
     applicable period.

     QUANTITY CONVERTED: The total amount of Active Material contained in the
     Products produced with the Quantity Dispensed (including any additional
     Products produced in accordance with Section 6.1 or 6.2), delivered by
     Patheon and, except as provided in Section 5.5(c), not rejected, recalled
     or returned in accordance with Section 6.1 or 6.2 as a result of a failure
     by Patheon to provide Manufacturing Services in accordance with
     Specifications and cGMPs.

Within 60 days after the end of each Year, Patheon shall prepare an annual
reconciliation of Active Material in accordance with the reconciliation report
form annexed hereto as Schedule I including the calculation of the "ACTUAL
ANNUAL YIELD" or "AAY" for the Product at the Manufacturing Site during the
Year, which AAY is the percentage of the Quantity Dispensed that was converted
to Products and is calculated as follows:

                       Quantity Converted during the Year
                       ----------------------------------
                       Quantity Dispensed during the Year

After Patheon has produced a minimum of [**] commercial and validation
production batches of Product and has produced commercial and validation
production batches for at least [**] months at a Manufacturing Site
(collectively, the "TARGET YIELD DETERMINATION BATCHES") pursuant to this
Agreement, the Parties will mutually agree on the target yield in respect of
such Product at such Manufacturing Site (each, a "TARGET YIELD"); provided,
however, that the Target Yield Determination Batches shall not include any
batches that, in Patheon's reasonable judgment,


                                      -7-

<PAGE>

were produced in production runs involving technical difficulties or involving
an extraordinary loss of Active Material. Thereafter, Patheon shall strive to
maintain Actual Annual Yield levels for each Product above the applicable Target
Yield.

     (b) Shortfall Calculation. If the Actual Annual Yield falls more than [**]
percent below the respective Target Yield in a Year, then the shortfall for such
Year (the "Shortfall") shall be determined based on the following calculation:

     [**]

The Shortfall shall be disclosed by Patheon to the Client on the reconciliation
report prepared in the form annexed hereto as Schedule I.

     (c) Reimbursement. Patheon shall reimburse the Client for any Shortfall in
a Year. Each payment under this Section 2.3 shall be summarized on the
reconciliation report prepared in the form attached hereto as Schedule I and
shall be made 30 days following the end of each Year.

     (d) Maximum Reimbursement. Notwithstanding the foregoing provisions of this
Section 2.3, Patheon's liability for Active Material calculated in accordance
with this Section 2.3 for any Product in a Year shall not exceed, in the
aggregate, the Maximum Reimbursement Value set forth in Schedule D hereto.

     (e) No Material Breach. It shall not constitute a material breach of this
Agreement by Patheon, for the purposes of Section 8.2(a), if the Actual Annual
Yield is less that the Target Yield.

<PAGE>

Services by Patheon, which Active Material shall be held by Patheon on behalf of
the Client on the terms and subject to the conditions herein contained. The
parties acknowledge and agree that title to the Active Material shall at all
times belong to and remain the property of the Client. Patheon agrees that any
Active Material received by it shall only be used by Patheon to provide the
Manufacturing Services. Patheon's liability with respect to any lost or damaged
Active Material shall be as set forth in Section 10.2(a).

                                    ARTICLE 4

                       CONVERSION FEES AND COMPONENT COSTS

4.1  FIRST YEAR PRICING.

     The fees for the Manufacturing Services (which fees include Component
costs) for the first Year are listed in Schedules B and C and are subject to the
adjustments set forth in Section 4.3.

4.2  SUBSEQUENT YEARS' PRICING.

     The fees for the Manufacturing Services provided pursuant to the terms of
this Agreement during any period following the first anniversary of this
Agreement shall be determined in accordance with the following:

     (a)  Manufacturing and Component Costs. On each yearly anniversary of this
          Agreement, Patheon shall be entitled to adjustment to the fees (i) for
          Manufacturing Services in respect of the Products to reflect
          inflation, which adjustment shall be based on the increase in the
          Consumer Price Index for All Urban Consumers published by US Bureau of
          Labor Statistics in September of the then current Year compared to the
          same month of the preceding Year, unless the parties otherwise agree
          in writing; and (ii) for Component costs to pass on the actual amount
          of any increase or decrease in such costs.

     (b)  Annual Forecast. To the extent that Patheon determines that the
          projections contained in the rolling forecast provided each [**]
          pursuant to Section 5.1(a) necessitate that an adjustment be made to
          the Manufacturing Services fees in respect of any Product, Patheon
          shall be entitled to request an appropriate price adjustment.

     (c)  Pricing Basis. The Client acknowledges that the fee for Manufacturing
          Services in respect of a Product in any Year is quoted based upon the
          Minimum Run Quantity and Annual Volume per Product specified in
          Schedule B or thereafter specified in the forecast provided pursuant
          to clause (b) of this Section 4.2 for the Year and is subject to
          change if the specified Minimum Run Quantity changes or if the Annual
          Volume is not met. For greater certainty, if Patheon and the Client


                                      -9-

<PAGE>

          agree that the Minimum Run Quantity in respect of a Product shall be
          reduced whether as a result of a decrease in Annual Volume or
          otherwise and, as a result of such reduction, Patheon's fees for
          services relating to such Product increase on a per unit basis, then
          Patheon shall be entitled to an increase in the fee for Manufacturing
          Services in respect of such Product by an amount sufficient to absorb
          such increase.

In connection with a fee adjustment pursuant to clause (a) of this Section 4.2,
Patheon shall deliver to the Client by not later than November 1st of each Year
a revised Schedule B in draft form and a statement outlining the percentage
increase in the US Consumer Price Index for All Urban Consumers upon which such
fee adjustment is based. In connection with all fee adjustment requests pursuant
to clauses (b) and (c) of this Section 4.2, Patheon shall deliver to the Client
by not later than November 1st of each Year a revised Schedule B in draft form
and such budgetary pricing information or other documentation reasonably
sufficient to demonstrate that a fee adjustment is justified, provided that
Patheon shall have no obligation to provide any supporting documents to the
extent such documents are subject to obligations of confidentiality by Patheon
to its suppliers. Upon delivery of such a request, each of the Client and
Patheon shall forthwith use all reasonable efforts to agree on a revised fee for
the Manufacturing Services in respect of each affected Product and Schedule B
shall be amended accordingly. Such revised fee shall be effective with respect
to any Product delivered after the end of the then current Year.

4.3  ADJUSTMENTS TO PRICING.

     During any Year of this Agreement, the fees set out in Schedule B shall be
subject to adjustment in accordance with the following:

     (a)  Volume Reduction. If at any time and from time to time Patheon
          determines, acting reasonably and based on the forecasts and Firm
          Orders received from the Client, that the current Minimum Run
          Quantities (including, without limitation, any permanent reductions in
          volumes) relating to a specific Product will constitute no more than
          [**]% of the Annual Volume for that Product specified in Schedule B
          hereto or, if applicable, any revised Annual Volume hereinafter agreed
          to by the parties, then Patheon shall be entitled to request an
          adjustment to the fee for Manufacturing Services in respect of that
          Product to reflect the increased costs that Patheon will incur as a
          result of the reduced volumes. If at any time and from time to time
          the Client determines, acting reasonably and based upon the forecasts
          and Firm Orders submitted to Patheon, that the current Minimum Run
          Quantities (including, without limitation, any permanent reduction in
          volumes) relating to a specific Product will constitute greater than
          [**]% of the Annual Volume for that Product specified in Schedule B
          hereto, or if applicable, any revised Annual Volume hereinafter agreed
          to by the parties, then the Client shall be entitled to request an
          adjustment to the fee for Manufacturing Services in respect of that
          Product to reflect the decreased costs that Patheon will incur as a


                                      -10-

<PAGE>

          result of the increased volumes. To the extent that the fee for
          Manufacturing Services in respect of a Product has been previously
          adjusted pursuant to this clause (a) to reflect reduced or increased
          volumes, the adjustment provided in this clause (a) shall operate
          based on the fees attributed to such Product at the time the last of
          such adjustments were made.

     (b)  Extraordinary Increases in Component Costs. If at any time market
          conditions result in Patheon's cost of Components being materially
          greater than normal forecasted increases, then Patheon shall be
          entitled to request an adjustment to the fee for Manufacturing
          Services in respect of any affected Product to compensate it for such
          increased Component costs. For the purposes of this clause (b),
          changes materially greater than normal forecasted increases shall be
          considered to have occurred if: (i) the cost of a Component increases
          by [**]% of the cost for that Component upon which the most recent fee
          quote was based; or (ii) the aggregate cost for all Components
          required to manufacture a Product increases by [**]% of the total
          Component costs for such Product upon which the most recent fee quote
          was based. To the extent that Component costs have been previously
          adjusted pursuant to clause (a) of Section 4.2 or this clause (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 then current price of the last adjustment to Component costs.

     (c)  Cost Reduction. Patheon agrees that it will attempt to increase the
          efficiency of the production process in order to reduce the cost of
          the Product. In the event that Patheon decreases the cost of
          manufacturing the Product, including, but not limited to, by reducing
          the cost basis of the Components utilized for the production of
          Product, whether such cost basis reduction is through the placement of
          bulk orders, change of vendors or otherwise in accordance with the
          terms of this Agreement, then [**]% of the net reduction of cost shall
          be credited to Client through a reduction of the fees per unit for the
          Product.

In connection with a fee adjustment request pursuant to this Section 4.3,
Patheon shall deliver to the Client a revised Schedule B and such budgetary
pricing information, adjusted Component costs or other documentation reasonably
sufficient to demonstrate that a fee adjustment is justified, provided that
Patheon shall have no obligation to provide any supporting documents to the
extent such documents are subject to obligations of confidentiality by Patheon
to its suppliers. Upon delivery of such a request, each of the Client and
Patheon shall forthwith use all reasonable efforts to agree on a revised fee for
the Manufacturing Services in respect of each affected Product and Schedule B
shall be amended accordingly.


                                      -11-

<PAGE>

4.4  ADJUSTMENTS DUE TO TECHNICAL CHANGES.

          Amendments to the Specifications or the Quality Agreement requested by
the Client, other than those mandated by the FDA or other government regulatory
agency (for which Client shall accept reasonable revision of the fees
necessitated by such amendment), will only be implemented following a technical
and cost review by Patheon and are subject to the Client and Patheon reaching
agreement as to revisions, if any, to the fees specified in Schedules B or C
necessitated by any such amendment. If the Client accepts a proposed fee change,
the proposed change in the Specifications shall be implemented, and the fee
change shall become effective only with respect to those orders of Products that
are manufactured in accordance with the revised Specifications. In addition, the
Client agrees to purchase, at Patheon's cost therefor (including all costs
incurred by Patheon in connection with the purchase and handling of such
Inventory), all Inventory utilized under the "old" Specifications and purchased
or maintained by Patheon in order to fill Firm Orders or in accordance with
Section 5.2, to the extent that such Inventory can no longer be utilized under
the revised Specifications. Open purchase orders for Components no longer
required under any revised Specifications that were placed by Patheon with
suppliers in order to fill Firm Orders or in accordance with Section 5.2 shall
be cancelled where possible, and where such orders are not subject to
cancellation without penalty, shall be assigned to and satisfied by the Client
and, at Client's option, Client shall take possession of the material in any
such orders. At Client's expense, Patheon shall deliver such Components to a
destination provided by Client.

4.5  MULTI-COUNTRY MANUFACTURING AND PACKAGING REQUIREMENTS.

          If and when the Client decides that it wishes to have Patheon
manufacture the Product for countries in addition to the Territory covered by
this Agreement, then the Client shall inform Patheon of the Component, Active
Material, Product, process and packaging requirements for each new country and
Patheon shall prepare a quotation for consideration by the Client of the
additional costs, if any, and the change over fees for the Product destined for
such new country. The agreed additional Component, Active Material, Product,
process and packaging requirements and related costs and change over fees shall
be set out in a written amendment to this Agreement.

                                    ARTICLE 5

           ORDERS, DELIVERY, INVOICING, PAYMENT, PRODUCT DEFICIENCIES

5.1  ORDERS AND FORECASTS.

     (a) Rolling Forecasts. Concurrent with the execution of this Agreement, the
Client shall provide Patheon with a written [**] forecast of the volume of each
Product that the Client then anticipates will be required to be produced by
Patheon and shipped to the Client or the


                                      -12-

<PAGE>

Client's designee during [**] and each [**] of Firm Orders (as defined below),
[**] of pro forma amounts of Product and [**] of planning horizon. Such forecast
will be updated by the Client [**] or before [**].

     (b) Firm Orders. On or before the [**] in conjunction with the provision of
the rolling forecast outlined in section 5.1(a), the Client shall issue firm
written orders ("FIRM ORDERS") for the Products to be produced and delivered to
the Client on a date not less than [**] from the first day of the calendar month
immediately following the date that the Firm Order is submitted. Such Firm
Orders submitted to Patheon shall specify the Client's purchase order number,
quantities by Product type, batch size, monthly delivery schedule and any other
elements necessary to ensure the timely production and shipment of the Products.
The quantities of Products ordered in such written orders shall be firm and
binding on the Client and shall not be subject to reduction by the Client.
Patheon shall have [**] to object in writing to the Client to any element of a
Firm Order. If Patheon does not object, then such Firm Order shall be binding on
Patheon and no part shall be subject to change by Patheon.

     (c) [**] Forecast. On or before [**], the Client shall provide Patheon with
a written [**] of the volume of each Product the Client then anticipates will be
required to be produced and shipped to the Client during the [**] period.

5.2  RELIANCE BY PATHEON.

          The Client understands and acknowledges that Patheon will rely on the
Firm Orders and rolling forecasts submitted pursuant to Section 5.1(a) and (b)
in ordering the Components required to meet such Firm Orders. In addition, the
Client understands that to ensure an orderly supply of such Components and/or to
achieve economies of scale in the costs, it may be desirable for Patheon to
purchase such Components in sufficient volumes to meet the production
requirements for Products during part or all of the first [**] of the forecasted
periods referred to in Section 5.1(a) or to meet the production requirements of
any longer period agreed to by Patheon and the Client. Accordingly, the Client
authorizes Patheon to purchase Components in order to satisfy the production
requirements for Products for the first [**] contemplated in the most recent
forecast provided by the Client pursuant to Section 5.1(a), and agrees that
Patheon may make such other purchases of Components to meet production
requirements during such longer periods as may be agreed to in writing from time
to time by the Client at the request of Patheon or the Client. Any requests made
by Client for product launch quantities of Product not contemplated in forecasts
or Firm Orders shall only be accepted by Patheon if made in writing by the
Client for the purposes of ordering Components and thereafter shall be treated
as a Firm Order. If Components ordered by Patheon pursuant to Firm Orders or
this Section 5.2 are not included in finished Products purchased by the Client
within [**] after the forecasted month in respect of which such purchases have
been made (or such longer period as the parties may agree) or if such Components
have expired during such period, then the Client shall pay to Patheon its costs
therefor (plus an additional [**]% handling fee); provided, however, that in the
event such unexpired Components are incorporated into Products


                                      -13-

<PAGE>

subsequently purchased by the Client or into third party products manufactured
by Patheon and subsequently purchased by a third party, the Client will receive
credit for any costs of such Components previously paid to Patheon by the
Client.


                                      -14-

<PAGE>

5.3  MINIMUM ORDERS.

          The Client may only order Products in multiples of the Minimum Run
Quantities set out in Schedule B.

5.4  SHIPMENTS.

          Shipments of Products shall be made EXW Patheon's shipping point
unless otherwise mutually agreed. Risk of loss or of damage to Products shall
remain with Patheon until Products are loaded onto the carrier's vehicle by
Patheon for shipment at the EXW point at which time risk of loss or damage shall
transfer to the Client. Patheon shall, in accordance with the Client's
instructions and as agent for the Client, (i) arrange for shipping, to be paid
by the Client and (ii) at the Client's risk and expense, obtain any export
license or other official authorization necessary to export the Products. The
Client shall arrange for insurance and shall 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. Products shall be transported in
accordance with the Specifications.

5.5  LATE SHIPMENT AND SHELF LIFE

          (a) Late Shipment. In the event that any Products are shipped to
Client more than 14 days after the agreed upon date (for reasons other than
Client's failure to deliver Active Material required to manufacture such
Products to Patheon within the time frames requested), the parties shall meet as
necessary in order to try to resolve the reasons, if any for the late shipment,
amicably. Should the parties fail to reach resolution under this Section 5.5,
then their dispute will be handled in accordance with Section 12.1 hereof.

          (b) The Product shall be delivered to Client or Client's designee as
set forth below ("DISTRIBUTION SHELF LIFE"):

However, if this is not achievable due to an out-of-specification or significant
batch deviation investigation, then the parties agree to work together to
maximize the shelf life of a batch of Product, including the packaging of the
subject Product into samples, if possible. At all times, the parties agree to
use commercially reasonable efforts to achieve a maximum distribution shelf life
and, in order to do so, if requested by Client, Patheon will [**]. The Client
shall have the right to reject any shipment of Products (other than Products
that were the subject of an out-of-specification or significant batch deviation
investigation), having less than the Distribution Shelf Life in accordance with
Section 6.1(a) hereof.

     In order to ensure that Client has sufficient time to review the Batch
Documentation to correct any defects in such documentation and release the
Product for shipment pursuant to a shipment request from Client:

     (1) for trade Product, Patheon will use best efforts to deliver the
     documentation package as defined in the Quality Agreement by [**] from the
     start of compounding. Both parties agree to cooperate to resolve any
     documentation issues by [**]; and

     (2) for sample Product, Patheon will use best efforts to deliver the
     documentation package as defined in the Quality Agreement by [**] from the
     start of compounding. Both parties agree to cooperate to resolve any
     documentation issues by [**].

     (c) Initial Batches. Notwithstanding the provisions of Section 5.5(b),
above or, anything else contained in this Agreement to the contrary, Patheon
shall not be liable for the loss of Active Material required to replace the [**]
shipments of Product rejected by Client for failure to meet the Distribution
Shelf Life provided such batches were manufactured by Patheon in accordance with
the Specifications and cGMPs.

5.6  INVOICES AND PAYMENT.

          Except as otherwise provided in this Agreement, Patheon shall charge
the Client for the Manufacturing Services only in respect of those Products that
are shipped to Client and shall submit to the Client, at the same time as each
shipment of Product, an invoice covering such shipment. Invoices shall be sent
by courier to such address as may be provided by the Client in writing from time
to time. Patheon shall also submit to the Client, with each shipment


                                      -16-

<PAGE>

of Products, a duplicate copy of the invoice covering such shipment. Patheon
shall also provide the Client with an invoice covering any Inventory or
Components which are to be purchased by the Client pursuant to the terms of this
Agreement. Each such invoice shall, to the extent applicable, identify the
Client purchase order number, Product numbers, names and quantities, unit price,
freight charges and the total amount to be remitted by the Client. The Client
shall pay all such invoices within 30 days of the date thereof.

                                    ARTICLE 6

                           PRODUCT CLAIMS AND RECALLS

6.1  PRODUCT CLAIMS.

          (a) Product Claims. The Client or its designated agent has the right
to reject any portion of any shipment of Products that deviates from the
Specifications or cGMPs, without invalidating any remainder of such shipment.
The Client or its designated agent shall inspect the Products manufactured by
Patheon within a reasonable time after the receipt thereof, including Batch
Documentation, and shall give Patheon written notice (a "DEFICIENCY NOTICE") of
all claims for Products that deviate from the Specifications or cGMPs within 30
days after the Client's or its designated agent's receipt thereof (or, in the
case of any defects not reasonably susceptible to discovery upon receipt of the
Product, within 30 days after discovery thereof by the Client, but in no event
after the expiration date of the Product). Should the Client fail to provide
Patheon with written notice of its acceptance or rejection of the delivery
within 30 days of receipt of a delivery of Products including Batch
Documentation, then the delivery shall be deemed to have been accepted by the
Client on the 31st day after delivery. Except as set out in Section 6.2, Patheon
shall have no liability for any deviations for which it has not received notice
within the applicable 30-day period.

          (b) Determination of Deficiency. Upon receipt of a Deficiency Notice,
Patheon shall have 10 days to advise the Client by notice in writing that it
disagrees with the contents of such Deficiency Notice. If the Client and Patheon
fail to agree within 10 days after Patheon's notice to the Client as to whether
any Products identified in the Deficiency Notice deviate from the Specifications
or cGMPs, then the parties shall mutually select an independent laboratory to
evaluate if any of the Products deviate from the Specifications or cGMPs. Such
evaluation shall be binding on the parties, and if such evaluation certifies
that any Products deviate from the Specifications or cGMPs, the Client may
reject those Products in the manner contemplated in this Section 6.1. If such
evaluation does not so certify in respect of any such Products, then the Client
shall be deemed to have accepted delivery of such Products on the 40th day after
delivery.

          (c) Patheon Responsibility. In the event the Client rejects Products
in accordance with this Section 6.1 and the deviation is determined to arise
from Patheon's failure to provide the Manufacturing Services in accordance with
the Specifications and cGMPs, Patheon will credit the Client's account for
Patheon's invoice price to the Client for such defective Products.


                                      -17-

<PAGE>

If the Client shall have previously paid for such defective Products, Patheon
shall promptly, at the Client's election, either: (i) refund the invoice price
for such defective Products; (ii) offset such amount against other amounts due
to Patheon hereunder; or (iii) replace such Products with conforming Products
without the Client being liable for payment therefor under Section 3.1,
contingent upon the receipt from the Client of all Active Material required for
the manufacture of such replacement Products. Subject to the limitations set out
in Section 10.2, Patheon shall be responsible for paying for any Active Material
needed under this Section 6.1(c) in accordance with the procedures set forth in
Section 2.3 hereof. Further, if it is determined that there is a deviation with
any part of the shipment of Product, at the Client's option, Patheon will take
receipt of such shipment and perform an inspection of 100% of the Product in the
shipment. The parties acknowledge that time is of the essence in meeting their
obligations under this Section 6.1(c).

     (d) Shortages. Claims for shortages in the amount of Product shipped by
Patheon shall be dealt with as may reasonably be agreed to by the parties;
provided, however, in the event that a shipment of Product received by Client or
its designee is less than [**]% of the amount ordered by Client pursuant to
Section 5.1(b) hereof ("SHORTAGE AMOUNT"), upon receipt of written request by
Client, Patheon shall use commercially reasonable efforts to manufacture
additional Product to replace the Shortage Amount. In the event that such
Shortage Amount is less than a validated batch size, then Patheon shall
manufacture the next highest validated batch size of Product ("SHORTAGE BATCH")
and package such Shortage Batch in accordance with the Client's written
instructions, including the Shortage Amount. The fees to be paid by the Client
for the Shortage Amount shall be the same unit price as set forth in the invoice
covering the shipment that is the subject of the Product Claim. The fees to be
paid by the Client for the balance of the Shortage Batch, if any, shall be the
next lowest priced fees payable by bottle count as set forth in Schedule B
hereto.

6.2  PRODUCT RECALLS AND RETURNS.

     (a) Records and Notice. Patheon and the Client shall each maintain such
records as may be necessary to permit a Recall of any Products delivered to the
Client or customers of the Client. Each party shall promptly notify the other by
telephone (to be confirmed in writing) of any information which might affect the
marketability, safety or effectiveness of the Products and/or which might result
in the Recall or seizure of the Products. Upon receiving any such notice or upon
any such discovery, each party 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 the Client. "RECALL" shall mean any action (i) by the Client
to recover title to or possession of quantities of the Products sold or shipped
to third parties (including, without limitation, the voluntary withdrawal of
Products from the market); or (ii) by any regulatory authorities to detain or
destroy any of the Products. Recall shall also include any action by either
party to refrain from selling or shipping quantities of the Products to third
parties which would have been subject to a Recall if sold or shipped.


                                      -18-

<PAGE>

     (b) Recalls. In the event (i) any governmental or regulatory authority
issues a directive, order or, following the issuance of a safety warning or
alert with respect to a Product, a written request that any Product be Recalled,
(ii) a court of competent jurisdiction orders such a Recall, or (iii) the Client
determines that any Product should be Recalled or that a "dear doctor" letter is
required relating the restrictions on the use of any Product, Patheon will
co-operate as reasonably required by the Client, having regard to all applicable
laws and regulations.

     (c) Product Returns. The Client or its designated agent shall have the
responsibility for handling customer returns of the Products. Patheon shall
provide the Client or its designated agent with such assistance as the Client
may reasonably require to handle such returns.

     (d) Patheon's Responsibility. To the extent that a Recall or return results
from, or arises out of, a failure by Patheon to provide the Manufacturing
Services in accordance with the Specifications and cGMPs, at Client's option,
Patheon shall be responsible for the documented out-of-pocket expenses of such
Recall or return and shall either (i) reimburse the Client for the price that
the Client paid to Patheon for manufacturing the Recalled Products or (ii) use
its commercially reasonable efforts to replace the Recalled or returned Products
with new Products at no charge to the Client, contingent upon the receipt from
the Client of all Active Material required for the manufacture of such
replacement Products. If Client elects to have the Recalled Product replaced,
subject to the limitations set out in Section 10.2, Patheon shall pay all costs
related to the Active Material required for the manufacture of replacement
Products in accordance with the procedures set forth in Section 2.3 hereof. In
all other circumstances, Recalls, returns or other corrective actions shall be
made at the Client's cost and expense. The parties acknowledge that time is of
the essence in meeting their obligations under this Section 6.2(d).

6.3  DISPOSITION OF DEFECTIVE OR RECALLED PRODUCTS.

          The Client shall not dispose of any damaged, defective, returned or
Recalled Products in relation to which it intends to assert a claim against
Patheon without Patheon's prior written authorization to do so. Alternatively,
Patheon may instruct the Client to return such Products to Patheon. Patheon
shall bear the cost of disposition with respect to any damaged, defective,
returned or Recalled Products in relation to which it bears responsibility under
Section 6.1 or 6.2 hereof. In all other circumstances, the Client shall bear the
cost of disposition with respect to any damaged, defective, returned or Recalled
Products.

6.4  CUSTOMER QUESTIONS AND COMPLAINTS.

          The Client or its designated agent shall have the full responsibility
for responding to questions and complaints from the Client's customers.
Questions or complaints received by Patheon from the Client's customers shall be
promptly referred to the Client. Patheon shall co-operate as reasonably required
to allow the Client to determine the cause of and resolve any customer questions
and complaints. Such assistance shall include follow-up investigations,


                                      -19-

<PAGE>

including testing. In addition, within 10 days from the date of request, Patheon
shall provide the Client with all necessary information that will enable the
Client 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
failure by Patheon to provide the Manufacturing Services in accordance with the
Specifications and cGMPs, all costs incurred in respect of this Section 6.4
shall be borne by the Client.

6.5  SOLE REMEDY.

          Except for the indemnity provided in Section 10.3 and subject to the
limitations set forth in Sections 10.1 and 10.2, the remedies described in this
Article 6 shall be the Client's sole remedy for any failure by Patheon to
provide the Manufacturing Services in accordance with the Specifications and
cGMPs.

          Each party shall forthwith upon execution of this Agreement appoint
one of its employees to be a relationship manager responsible for liaison
between the parties. The relationship managers shall meet not less than
quarterly to review the current status of the business relationship and manage
any issues that have arisen.

7.2  GOVERNMENTAL AGENCIES.

          Subject to Section 7.7, 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 any
communications with the agency, and to receive copies of all such communications
to and/or from the agency.

7.3  RECORDS AND ACCOUNTING BY PATHEON.

          Patheon shall keep records of the manufacture, testing and shipping of
the Products, Components and Active Material, and retain samples of such
Products, Components and Active Material as are necessary to comply with
manufacturing regulatory requirements applicable to Patheon, as well as to
assist with resolving Product complaints and other similar


                                      -20-

<PAGE>

investigations. Copies of such records and samples shall be retained for a
period of one year following the date of Product expiry, or longer if required
by law or the Quality Agreement. Patheon is responsible for retaining samples of
the Products, Components and Active Material either that are necessary to comply
with the legal/regulatory requirements applicable to the Client or that are
requested by the Client. For the avoidance of doubt, if a Component or Active
Material is used in more than one batch of Product, Patheon shall retain the
necessary samples for a period of one year following the date of Product expiry,
or longer if required by law, for the final batch of Product made with such
Component or Active Material. Prior to destroying any records or retained
samples under this Section 7.3, Patheon shall notify the Client and the Client
shall have the option of having such records or retained samples sent to a
location of the Client's choice at the Client's expense.

7.4  INSPECTION.

          The Client may inspect Patheon reports and records relating to this
Agreement during normal business hours and with reasonable advance notice. A
Patheon representative shall be present during any such inspection.

7.5  ACCESS.

          Patheon shall provide the Client with reasonable access at mutually
agreeable times to any of its facilities in which the Products are manufactured,
stored, handled or shipped in order to permit the Client's verification of
Patheon's compliance with the Patheon Manufacturing Responsibilities and with
all applicable laws and regulations. For greater certainty, the right of access
provided in this Section 7.5 shall not include a right to access or inspect
Patheon's financial records. Patheon shall notify the Client of any inspections
by any governmental agency directly or indirectly involving the Products.

7.6  REPORTS.

          Patheon will supply all Product data, including release test results,
complaint test results, all investigations (in manufacturing, testing and
storage), and the like, that the Client reasonably requires in order to complete
any filing under any applicable regulatory regime, including any annual product
report information that the Client is required to file with the FDA, thirty (30)
days prior to the due date for such report or filing. At the Client's request
and subject to an additional fee to be agreed by the parties, Patheon may
prepare annual product review information on behalf of the Client and in
accordance with the Client's instructions.

7.7  FDA FILINGS

     (a) FDA Filings. The Client shall have the sole responsibility for filing
all documents with the FDA and taking any other actions that may be required to
maintain FDA Approval for the commercial manufacture of all of the Products.

obligations under this Agreement. Client shall provide Patheon with


                                      -21-

<PAGE>

copies of all FDA filings at the time of submission which contain chemistry,
manufacturing and controls (CMC) information regarding the Product.

     (b) Verification of Data. Prior to filing any documents with the FDA that
incorporate data generated by Patheon that has a material change to such data
made by Client, the Client shall provide Patheon with a copy of the documents
incorporating such data so as to give Patheon the opportunity to verify the
accuracy and regulatory validity of such documents as they relate to the Patheon
generated data. The standard review period is 30 days, however shorter times
shall be satisfactory upon agreement of the parties.

     (c) Client Responsibility. For clarity, the parties agree that in reviewing
the documents referred to in paragraph (b) above, Patheon's role will be limited
to verifying the accuracy of the description of the work undertaken or to be
undertaken by Patheon. As such, Patheon shall not assume any responsibility for
the accuracy of the NDA or the ANDA, as the case may be. The sole responsibility
of the preparation and filing of the NDA or the ANDA shall be borne by the
Client.

7.8  TECHNOLOGY TRANSFERS.

          Provided that the Client is not then in breach of its obligations
under this Agreement, Patheon shall, at the Client's expense, provide such
assistance as is reasonably necessary to assist the Client in transferring the
manufacture of Product to another facility including manufacturing processes and
analytical methods; provided, however, no competitor of Patheon shall be
permitted to have access to the Manufacturing Site.

          In the event of any dispute arising out of or in connection with this
Agreement (other than a dispute determined in accordance with Section 6.1(b) or
a Technical Dispute), the parties shall first try to solve it amicably. In this
regard, any party may send a notice of dispute to the other, and each party
shall appoint, within 10 Business Days from receipt of such notice of dispute, a
single representative having full power and authority to solve the dispute. The

efforts to resolve the dispute by amicable negotiations. In this regard, senior
representatives of each party shall, as soon as practicable and in any event no
later than 10 Business Days after a written request from either party to the
other, meet in good faith to resolve any Technical Dispute. If, despite such
meeting, the parties are unable to resolve a Technical Dispute within a
reasonable time, and in any event within 30 Business Days of such written
request, the Technical Dispute shall, at the request of either party, be
referred for determination to an expert in accordance with the provisions of
Schedule F. In the event that the parties cannot agree whether a dispute is a
Technical Dispute, Section 12.1 shall prevail. For greater certainty, the
parties agree that the release of the Products for sale or distribution pursuant
to the applicable marketing approval for such Products shall not by itself
indicate compliance by Patheon with its obligations in respect of the
Manufacturing Services and further that nothing in this Agreement (including
Schedule F) shall remove or limit the authority of the relevant qualified person
(as specified by the Quality Agreement) to determine whether the Products are to
be released for sale or distribution.

                                  MISCELLANEOUS

13.1 INVENTIONS.

     (a) For the term of this Agreement, Client hereby grants to Patheon a
non-exclusive, paid-up, royalty-free, non-transferable license of Client's
Intellectual Property which Patheon must use in order to perform the
Manufacturing Services.

     (b) All Intellectual Property generated or derived by Patheon in the course

subject of the Manufacturing Services, shall be the exclusive property of the
Client.

     (c) All Intellectual Property generated or derived by Patheon in the course
of performing the Manufacturing Services which are not specific, or dependent
upon, Client's Product and which have application to manufacturing processes or
formulation development of drug products or drug delivery systems shall be the
exclusive property of Patheon (the "Broader Intellectual Property Rights").
Patheon hereby grants to Client, a non-exclusive, paid-up, royalty-free,
transferable license of Patheon's Broader Intellectual Property Rights which
Client may use for the manufacture of Client's Product.

     (d) Each party shall be solely responsible for the costs of filing,
prosecution and maintenance of patents and patent applications on its own
Inventions.

     (e) Either party shall give the other party written notice, as promptly as

13.2 INTELLECTUAL PROPERTY.

          Subject to Section 13.1, all Intellectual Property of the Client shall
be owned by the Client and all Intellectual Property of Patheon shall be owned
by Patheon. The Client and Patheon hereby acknowledge that neither party has,
nor shall it acquire, any interest in any of the other party's Intellectual
Property unless otherwise expressly agreed to in writing. Each party agrees not
to use any Intellectual Property of the other party, except as specifically
authorized by the other party or as required for the performance of its
obligations under this Agreement.

13.3 INSURANCE.

          Each party shall use commercially reasonable efforts to maintain
commercial general liability insurance covering the obligations of that party
under this Agreement through the term of this Agreement and for a period of
three years thereafter, which insurance shall afford limits of not less than
$5,000,000 for each occurrence of products liability and property damage
liability. If requested 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 effective date, the expiration date and the limits of
liability. The insurance certificate shall further provide for a minimum of 30
days' written notice to the insured of a cancellation of, or a material change
in, the insurance. If a party is unable to maintain the insurance policies
required under this Agreement through no fault on the part of such party, then
such party shall forthwith notify the other party in writing and the parties
shall in good faith negotiate appropriate amendments to the insurance provision
of this Agreement in order to provide adequate assurances.

13.4 INDEPENDENT CONTRACTORS.

          The parties are independent contractors and this Agreement shall not
be construed to create between Patheon and the Client any other relationship
such as, by way of example only, that of employer-employee, principal agent,
joint-venturer, co-partners or any similar relationship, the existence of which
is expressly denied by the parties hereto.

13.5 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 or
any other provision of this Agreement.

13.6 ASSIGNMENT.

          Patheon may not assign this Agreement or any of its rights or
obligations hereunder except with the written consent of the Client, such
consent not to be unreasonably withheld. For greater certainty, Patheon may
arrange for subcontractors to perform specific services arising under this
Agreement provided that Patheon remains responsible to the Client


                                      -31-

<PAGE>

under this Agreement. Subject to Section 8.2(d), the Client may assign this
Agreement or any of its rights or obligations hereunder without approval from
Patheon; provided, however, that the Client shall give prior written notice of
any assignment to Patheon, any assignee shall covenant in writing with Patheon
to be bound by the terms of this Agreement and the Client shall remain liable
hereunder. Notwithstanding the foregoing provisions of this Section 13.6, 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.

13.7 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, acts of
terrorism, fires, floods, storms, inability to obtain fuel, power, or components
or compliance with any order or regulation of any government entity acting
within colour of right (a "Force Majeure Event"). A party claiming a right to be
excused performance under this Section 13.7 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. Neither party shall be entitled to rely on a Force Majeure Event to
relieve it from an obligation to pay money (including any interest for delayed
payment) which would otherwise be due and payable under this Agreement.

13.8 ADDITIONAL PRODUCT.

          Additional products may be added to this Agreement and such additional
products shall be governed by the general conditions hereof with any special
terms (including, without limitation, price) governed by an addendum hereto.

in Section 12.2 shall be resolved in the following matter:

1. APPOINTMENT OF EXPERT. Within 10 Business Days after a party requests
pursuant to Section 12.2 that an expert be appointed to resolve a Technical
Dispute, the parties shall jointly appoint a mutually acceptable expert with
experience and expertise in the subject matter of the dispute. If the parties
are unable to so agree within such 10 Business Day period, or in the event of
disclosure of a conflict by an expert pursuant to paragraph 2 hereof which
results in the parties not confirming the appointment of such expert, then an
expert (willing to act in that capacity hereunder) shall be appointed by an
experienced arbitrator on the roster of the American Arbitration Association.

2. CONFLICTS OF INTEREST. Any person appointed as an expert shall not be
entitled to act and continue to act as such notwithstanding that at the time of
his appointment or at any time before he gives his determination, he has or may
have some interest or duty which conflicts or may conflict with his appointment
without the express written consent of the parties.

3. NOT ARBITRATOR. No expert shall be deemed to be an arbitrator and the
provisions of The American Arbitration Act or of any other applicable statute
(foreign or domestic) and the law relating to arbitration shall not apply to any
such expert or the expert's determination or the procedure by which the expert
reaches his determination to be made pursuant to this Schedule F.

4. PROCEDURE. Where an expert is appointed:

     (a)  Timing. The expert shall be so appointed on condition that (i) he
          promptly fixes a reasonable time and place for receiving
          representations, submissions or information from the parties and that
          he issues such authorizations to the parties and any relevant third
          party for the proper conduct of his determination and any hearing and
          (ii) he renders his decision (with full reasons) within 15 Business
          Days (or such other date as the parties and the expert may agree)
          after receipt of all information requested by him pursuant to
          paragraph 4(b) hereof.

     (b)  Disclosure of Evidence. The parties undertake one to the other to
          provide to any expert all such non-privileged evidence and information
          within their respective possession or control as the expert may
          reasonably consider necessary for determining the matter before him
          which they shall disclose promptly and in any event within five
          Business Days of a written request from the relevant expert to do so.

     (c)  Advisors. Each party may appoint such counsel, consultants and
          advisors as it feels appropriate to assist the expert in his
          determination and so as to present their respective cases so that at
          all times the parties shall co-operate and seek to narrow and limit
          the issues to be determined.

     (d)  Appointment of New Expert. If within the time specified in paragraph
          4(a) above the expert shall not have rendered a decision in accordance
          with his appointment, a new expert may (at the request of either
          party) be appointed and the appointment of the existing expert shall
          thereupon cease for the purposes of determining the matter at issue
          between the parties save that if the existing expert renders his
          decision with full reasons prior to the appointment of the new expert,
          then such a decision shall have effect and the proposed appointment of
          the new expert shall be withdrawn.

     (e)  Final and Binding. The determination of the expert shall, save in the
          event of fraud or manifest error, be final and binding upon the
          parties.

     (f)  Costs. Each party shall bear its own costs in connection with any
          matter referred to an expert hereunder and, in the absence of express
          provision in the Agreement to the contrary, the costs and expenses of
          the expert shall be shared equally by the parties.

For greater certainty, the parties agree that the release of the Products for
sale or distribution pursuant to the applicable marketing approval for such
Products shall not by itself indicate compliance by Patheon with its obligations
in respect of the Manufacturing Services and further that nothing in this
Agreement (including this Schedule F) shall remove or limit the authority of the
relevant qualified person (as specified by the Quality Agreement) to determine
whether the Products are suitable to be released for sale or distribution.

EFFECTIVE DATE: MAY 20, 2004

PARTIES:

<TABLE>
<S>                                <C>                            <C>

</TABLE>

This Confidentiality Agreement (the "AGREEMENT") is entered into as of the
Effective Date by and between the parties identified above. As used herein, the
party disclosing information shall be referred to as the "DISCLOSING PARTY" and
the party or parties receiving such information shall be referred to as the
"RECIPIENT".

As a condition of the Disclosing Party furnishing any Information (defined
below) to the Recipient, the parties agree as follows:

1. INFORMATION. "INFORMATION" is any information disclosed by the Disclosing
Party to the Recipient (whether disclosed in oral, written, electronic or visual
form) that is non-public, confidential or proprietary including, without
limitation, information relating to the Disclosing Party's intellectual
property, its customers, finance, marketing, products research, data, know-how
and processes. Information shall be marked or clearly identified as such prior
to or at the time of disclosure. All analyses, compilations, studies, reports or
other documents prepared by any party's directors, officers, employees,
advisers, agents, consultants or representatives (collectively,
"REPRESENTATIVES") containing such Information and all price quotations,
manufacturing or professional services proposals and other information relating
to Patheon's manufacturing capabilities and operations shall be deemed to be
Information.

2. USE OF INFORMATION. The Recipient shall use the Information solely for the
purpose of investigating and implementing a potential business relationship
between the parties (the "PURPOSE"). The Recipient shall keep the Information
strictly confidential and shall not disclose the Information in any manner
whatsoever, in whole or in part, other than to those of its Representatives who
(i) have a need to know such Information for the Purpose and (ii) have entered
into a confidentiality agreement with the Recipient that is reasonably
calculated to protect the confidential or proprietary nature of the Information
and prohibit its disclosure. Recipient shall protect the Information by using
all reasonable precautions to prevent the unauthorized disclosure of the
Information, which precautions shall in no event be less than the Recipient's
treatment of its own confidential or proprietary information of a similar
nature.

3. EXCLUSIONS. The obligations of confidentiality set forth in Section 2 shall
not apply to Information to the extent that such Information:

     (a)  is or becomes publicly known through no fault of the Recipient or its
          Representatives;

     (b)  is in the Recipient's possession at the time of disclosure by the
          Disclosing Party other than as a result of the Recipient's breach of
          any legal obligation;

     (c)  is or becomes known to the Recipient through disclosure by sources,
          other than the Disclosing Party, having the legal right to disclose
          such Information;

     (d)  is independently developed by or for the Recipient without use of or
          reference to the Disclosing Party's Information as evident by
          Recipient's written records;

     (e)  is expressly authorized for release by the written authorization of
          the Disclosing Party; or

     (f)  is required to be disclosed by law (or rules of any self-regulatory
          organization having the force of law) or by any regulatory or
          governmental authority, provided that the Recipient promptly notifies
          the Disclosing Party and makes reasonable efforts to maintain the
          confidentiality of the Information in any required disclosure.

Any combination of information which comprises part of the Information shall not
be deemed to be exempt from the obligations of confidentiality merely because
individual parts of that information were publicly known, in the Recipient's
possession, or received by the Recipient, unless the combination itself was
publicly known, in the Recipient's possession, or received by the Recipient.

4. MARKING. The Disclosing Party agrees to use reasonable efforts to summarize
in writing the content of any oral disclosure or other non-tangible disclosure
of Information within 30 days of the disclosure, but


                                       26

<PAGE>

failure to provide such summary shall not affect the nature of the Information
disclosed if such Information was identified as confidential or proprietary when
disclosed orally or in any other non-tangible form.

5. RETURN OF INFORMATION. Upon the request of the Disclosing Party, the
Recipient shall promptly return to the Disclosing Party or, if the Disclosing
Party directs in writing, destroy all Information disclosed in or reduced to
tangible form including any copies thereof and shall destroy any summaries,
compilations, analyses or other notes derived from the Information except for
one copy which shall be maintained by the Recipient only if it is necessary to
maintain a copy for any legal or regulatory requirement.

6. REMEDIES. The parties acknowledge that monetary damages would not be
sufficient to remedy a breach by either party of this Agreement and agree that
each party shall be entitled to seek injunctive relief to prevent breaches of
this Agreement and to specifically enforce the provisions hereof in addition to
any other remedies available at law or in equity.

7. NO WARRANTY. All Information is provided "as is" and without any
representation or warranty, whether express or implied, as to its accuracy or
completeness.

8. RIGHTS. Neither party acquires any intellectual property rights, including
patents, designs, trade-marks, copyright or trade secrets under this Agreement,
except the limited right to use the Information to carry out the Purpose.

9. TERMINATION. This Agreement shall terminate on the earlier of (i) five years
after the Effective Date, or (ii) the written agreement of the parties.
Notwithstanding the earlier termination of this Agreement, the obligations of
confidentiality set forth herein shall continue for five years from the date of
disclosure of Information hereunder.

10. DATA TRANSFER. Unless otherwise agreed in writing, any personally
identifiable information provided by one party to the other hereunder may only
be used for conducting the business transaction(s) that is the subject of this
Agreement. Neither party consents to the other party's use of any personally
identifiable information provided by the Disclosing Party or its Representatives
for any direct marketing, nor to the transfer of such information to any third
party.

11. GENERAL.

(a)  This Agreement constitutes the full understanding between the parties with
     respect to the subject matter hereof and supersedes all prior agreements
     and understandings, whether written or oral, relating thereto.

(b)  No amendment or waiver of any provision of this Agreement shall be binding
     unless given in writing by the party to be bound thereby.

(c)  No failure or delay by either party in exercising any right hereunder shall
     operate as a waiver thereof.

(d)  This Agreement shall be binding on, and shall enure to the benefit of the
     parties and their respective successors.

(e)  This Agreement shall be governed by the laws of the State of Deleware.

(f)  This Agreement is not assignable by the parties. Any purported assignment
     of this Agreement shall be void.

(g)  Should any provision of this Agreement be found invalid or unenforceable by
     law, it shall cease to operate and be considered severed from this
     Agreement. All remaining provisions shall continue to be valid and binding
     on the parties.

(h)  This Agreement may be executed in separate counterparts, and by facsimile,
     each of which when so executed and delivered shall be an original and all
     such counterparts shall together constitute one and the same instrument.
