       in Exhibit A.

       efforts to meet Client's volume requirement.

2.4    Packaging.  Patheon  shall  package the  Products  with  labels,  product
       inserts and other labeling as specified in Exhibit A-1. 1t is agreed that
       the product  Prenate Advance listed on Exhibit A at the date hereof is to

              but not limited to, the U.S.  Federal Food,  Drug and Cosmetic Act
              and the regulations  promulgated  thereunder (such as current Good

                                       3
<PAGE>

              time   to   time,   and   (ii)   the   Specifications.   Patheon's
              responsibilities  and  obligations   described  in  the  foregoing
              sentence are hereinafter referred to as the "Patheon Manufacturing
              Requirements".

       (b)    Patheon shall perform such quality  control and quality  assurance
              testing as is required to ensure that the Products comply with all
              of the Patheon Manufacturing Requirements.

       (c)    If  the  Products  as  manufactured  by  Patheon  do  not  satisfy
              Patheon's  quality  control and quality  assurance  testing due to
              Patheon's  failure to produce the Products in accordance  with the
              Patheon  Manufacturing  Requirements,  Patheon shall,  at its sole
              cost and expense,  manufacture additional Products to replace such
              defective Products.  In such  circumstances,  Client shall have no
              obligation to purchase or pay for any rejected Products.

       (d)    The parties  hereto agree that Patheon shall not be liable or have
              any  responsibility  for any deficiencies in, or other liabilities
              associated with, the formulae and procedures  specified by Client,
              the  safety,  efficacy  or  marketability  of the  Products or any
              distribution risk.

       (e)    Each time  Patheon  ships  Products  to Client,  it shall  provide
              Client with a  certificate  of  analysis  that sets out the actual
              test results for each lot of Products and which certifies that the
              Products  shipped  to Client  have  been  evaluated  by  Patheon's
              Quality Control/Quality Assurance department and that the Products
              comply with the Patheon Manufacturing Requirements.  Patheon shall
              not under  any  circumstances  ship  Non-Conforming  Products  (as
              defined in Section 2.6(a)) to Client.

2.6    Rejection of Products.

     (a)  Client  shall  inspect the  Products  manufactured  by Patheon  within
          thirty (30) business days after receipt thereof and shall give Patheon
          written notice (a "Deficiency  Notice") of all claims for (i) Products
          which do not conform to the Patheon Manufacturing  Requirements or the
          tests results as shown on the  Certificate  of Analysis (such Products
          being  referred  to  herein  as  "Non-Conforming  Products"),  or (ii)
          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 4.2 and 4.3 below,  Patheon  shall have no liability  for any
          deviations  or shortages  for which it has not received  notice within
          such  thirty  (30) day  period.  Client  shall  return,  at  Patheon's
          expense,  any  Non-Conforming  Product.  Cost and  method of  returned
          Non-Conforming Product disposal shall be Patheon's responsibility.

                                       4
<PAGE>

       (b)    Upon  receipt of a  Deficiency  Notice  relating  to claims  under
              2.6(a)(i)  above,  Patheon  shall have 10 business  days to notify
              Client  in  writing  as to  whether  it  agrees  that the  subject
              Products are Non-Conforming  Products.  If Client and Patheon fail
              to agree within 10 business days after Patheon's  notice to Client
              as to whether any Products identified in the Deficiency Notice are
              Non-Conforming  Products,  the parties shall mutually determine an
              independent  laboratory  to  evaluate  whether  the  Products  are
              Non-Conforming  Products.  If such  evaluation  certifies that any
              Products  are  Non-Conforming  Products,  Client  may  have  those
              Products replaced in the manner contemplated by Subsection 2.6(d).

       (c)    Claims for shortages set out in a Deficiency  Notice  delivered to
              Patheon  pursuant to Subsection  2.6(a)(ii) shall be dealt with in
              accordance with normal commercial practices.

       (d)    All  fees  and  disbursements  incurred  in  connection  with  the
              independent  determination  by  the  laboratory  as  described  in
              Section 2.6(b) above shall be borne by the party which  determined
              incorrectly   that  the   relevant   Product  was  or  was  not  a
              Non-Conforming Product. Within 15 days of the determination by the
              independent  laboratory  that  the  product  is  a  Non-Conforming
              Product,   Patheon  shall  replace  such  returned  Non-Conforming
              Product  at  its  expense  or if  it  is  unable  to  make  prompt
              replacement,  shall either credit  Client's  account or refund any
              payment  made  on the  rejected  Product,  depending  on  Client's
              account balance.

2.7    Stability  Testing.  Patheon  shall  conduct  stability  testing  on  the
       Products  as  required  by GMPs  and in  accordance  with  the  protocols
       approved  by Client,  the  particulars  of which form part of the annexed
       Exhibit D, and in accordance with the fee schedule attached as Exhibit D.
       Patheon  shall not make any changes to these testing  procedures  without
       prior written approval from Client. In the event that any lot of Products
       fails stability  testing,  Patheon and Client 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. Patheon will provide any and all data and results relating
       to the  stability  testing  upon  request by  Client.  From time to time,
       Patheon shall, at the request of Client,  also provide  stability testing
       services with respect to products not  manufactured by Patheon,  the cost
       of such  services  to be  agreed to  between  the  parties  prior to such
       services being undertaken.

3.0    ORDERS, DELIVERY, INVOICING AND PAYMENT

3.1    Yearly Forecast. On the execution of this Agreement, Client shall provide
       Patheon with a forecast of the volume of each Product required during the
       first year of this Agreement.

3.2    Orders/Forecasts.  During the term of this Agreement,  Client shall, on a
       monthly  basis,  submit to Patheon a twelve (12) month  rolling  forecast
       that sets forth the total quantity of product that the Client has ordered
       and expects to order from  Patheon  within the twelve (12) month  period.

                                       5
<PAGE>
                                       [***] -  CONFIDENTIAL TREATMENT REQUESTED

       The first three (3) months of such  forecast  are to be  considered  firm
       orders (the "Firm Orders"). Firm Orders will be accompanied by a purchase
       order.  Each  forecast  will be  provided  to  Patheon  no later than the
       fifteenth (15th) of each month.

3.3    Written  Orders.  The  Firm  Orders  submitted  to  Patheon  pursuant  to
       Subsection 3.2 shall specify Client's  purchase order number,  quantities
       by  Product  type,  monthly  delivery  schedule  and any  other  elements
       necessary to ensure the timely  production  and delivery of the Products.
       The quantities of Products  ordered in such Firm Orders shall be firm and
       binding on Client and shall not be subject to  reduction.  Patheon  shall
       provide  written  confirmation  of receipt  of Firm  Orders to the Client
       within ten (10) calendar days of receipt thereof.

3.4    Reliance by Patheon.  Client agrees that purchases may be made by Patheon
       of the Components to satisfy the production  requirements for Firm Orders
       and  may  make  such  other  purchases  to meet  production  requirements
       exceeding  Firm Order  requirements  as may be agreed to in writing  from
       time  to time by  Client  and  Patheon.  In such  circumstances,  if such
       Components  are not  included in finished  Products  purchased  by Client
       within six months  after such  purchases  have been made (or such  longer
       period as the parties may have agreed to), Client will pay to Patheon its
       costs thereof and, in the event such  Components  are  incorporated  into
       Products subsequently purchased by Client, Client will receive credit for
       any of such costs previously paid to Patheon by Client.

3.5    Minimum Orders.  The Products to be manufactured  and packaged by Patheon
       may only be ordered in the following  minimum order run quantities  [***]
       of [***] tablets per batch.

3.6  Late  Shipments.  Patheon  agrees  that  time  is of the  essence  of  this
     Agreement.  If  Patheon  becomes  aware  that it will not meet a  scheduled
     delivery date,  Patheon will promptly  communicate  this to Client.  In the
     event of  repeated  late  deliveries,  Patheon  and  Client  shall  meet to
     determine a mutually  satisfactory  solution to this problem. If after such
     meetings, there are continued late deliveries,  Client shall be entitled to
     treat same as a material  breach of this  Agreement  and the  provisions of
     Section 5.3(a) hereof shall apply and the time period  specified in Section
     5.3(a) shall commence.

3.7    Termination.  If this  Agreement  expires or is terminated in whole or in
       part  for any  reason  other  than a  default  by  Patheon  as set out in
       subsection 5.3(a) or (b), Client shall (in addition to any other remedies
       Patheon may have in the event of default by Client):

       (a)    purchase,  at Patheon's  cost,  the  Inventory  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;

                                       6
<PAGE>

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

       (c)    satisfy the purchase  price payable  pursuant to Patheon's  orders
              with  suppliers of  Components  provided  such orders were made by
              Patheon in reliance on Firm Orders.

       If this  Agreement  is  terminated  as a result of a default by  Patheon,
       Client shall have the option to purchase such of the items referred to in
       (a), (b) and (c) above if it determines in its absolute  discretion  that
       the items can be used by it.

3.8    Specifications.  All Components  shall be purchased and tested by Patheon
       at  Patheon's   expense  in   accordance   with   Patheon   Manufacturing
       Requirements.   Patheon  will  not  change  the  Specifications  used  to
       manufacture,  test,  package  and ship the  Products  without the written
       consent of Client.  Amendments to Specifications requested by Client will
       only be  implemented  following a technical  and cost review,  subject to
       Client and Patheon reaching agreement as to price revisions  necessitated
       by any such amendment in accordance with Section 3.9 below.

3.9    Change in Specifications.

       (a)    If Client  requests  a change in the  Specifications  which  would
              result  in  an  increase  or  decrease  in  Patheon's   costs  for
              Components or would cause Patheon to incur other costs as a result
              of the change in Specifications,  the parties shall discuss,  each
              acting reasonably and based on satisfactory documentation provided
              by Patheon indicating the cause of the price change,  what impact,
              if any,  such change  should have on the price of the Products and
              payment  to  Patheon  of the  related  costs.  If  Client,  acting
              reasonably,  accepts a proposed price change,  the proposed change
              in the 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
              Specifications.

       (b)    Notwithstanding  any change in the  Specifications  implemented in
              accordance with the terms of (a) above,  Client agrees to purchase
              all  Products   manufactured  by  Patheon  based  upon  any  "old"
              Specifications  at the then-current  price for those Products.  In
              addition,  Client  agrees to  purchase,  at  Patheon's  cost,  all
              Inventory,  utilized under the "old"  Specifications and purchased
              or maintained  by Patheon in order to fill Firm written  Orders 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 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 Client.

                                       7
<PAGE>

       (c)    If a change in  Specifications  must be made by Client solely as a
              result of Patheon's  acts or  omissions,  the parties will meet to
              determine  who will bear any costs arising from such change in the
              Specifications.

3.10   Shipments.  Patheon  shall ship and  deliver the  Products  at  Patheon's
       premises  at 2100  Syntex  Court,  Mississauga,  Ontario  to such  Client
       locations as requested  by Client and at Client's  expense.  Client shall
       select the freight  carrier  used by Patheon to ship the Products and may
       monitor  Patheon's  shipping/freight  practices  as they  pertain to this
       Agreement.  Risk of loss and title shall pass to Client upon  delivery by
       Patheon to the freight carrier selected by Client at Patheon's  premises.
       For greater  certainty,  Patheon agrees that it will be  responsible  for
       preparation,  at Client's expense, of all shipping  documents,  including
       customs formalities for export of the Products.

3.1l   Invoices and Payment.  Except as  otherwise  provided in this  Agreement,
       Patheon shall charge  Client for only those  Products that are shipped to
       Client and shall submit to Client,  with each  shipment of  Products,  an
       invoice  covering such shipment.  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 Client.  Client shall pay all such invoices  within thirty
       (30) days of the receipt thereof.

3.12   Lot  Numbering/Expiration  Dates. Patheon shall make arrangements for and
       implement the imprinting of lot numbers,  expiration dates,  retest dates
       or  "package-by"  dates,  as  applicable,  on each  Product  container as
       required  by GMPs for each  Product  shipped.  Such lot numbers and dates
       shall be affixed on the Products  and/or on the  shipping  carton of each
       product  as is  required  by GMPs.  The system  used by  Patheon  for lot
       numbering and expiration dates is detailed on Exhibit E hereto.

4.0    CO-OPERATION

4.1    Records and  Accounting  by Patheon.  Patheon  shall keep  records of the
       manufacture,  testing and shipping of the Products, and retain samples of
       such Products in order to comply with applicable  regulations,  including
       the requirements of the United States Code of Federal Regulations ("CFR")
       as well as to assist with resolving product  complaints and other similar
       investigations.  Copies  of  such  records  and  samples  shall  be  made
       available to Client upon its request and shall be retained by Patheon and
       be available to Client for a period of one (1) year after the  expiration
       dates of the packaged batch, or longer if required by law,  including the
       CFR.

4.2    Product Recalls.

       (a)    Patheon and Client shall each maintain records as may be necessary
              to  permit  a recall  or a field  correction  of any the  Products
              delivered to Client or customers of Client,  effected  voluntarily
              or under a threat of, or a directive by, any governmental  agency.
              Each party shall give notice  within 24 hours by telephone  (to be
              confirmed in writing) to the  Director of Quality  Control/Quality

                                       8
<PAGE>

              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 Client.  Patheon  will  co-operate  as  reasonably
              required  by  Client,  having  regard to all  applicable  laws and
              regulations.  Each  party  shall  co-operate  with  the  other  in
              developing any necessary recall plan, and the manner and extent of
              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  then (i) such
          recall and all reasonable expenses associated with the 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 Client  notifies  Patheon about the
          recalled Products.  In the event that (i) 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 (ii) such new Products  are also  recalled or returned
          due to a breach by Patheon of the Patheon Manufacturing  Requirements,
          then Client may request  Patheon to reimburse  Client for the purchase
          price that Client paid Patheon for the affected Products. In all other
          circumstances, recalls shall be made at Client's cost and expense.

4.3    Product  Returns.  Client  shall  have the  responsibility  for  handling
       customer returns of the Products.  Patheon shall provide Client with such
       assistance as Client 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  best  efforts  to  replace  the  returned  Products  with new
       Products  within  sixty  (60)  days from the date  that  Client  notifies
       Patheon about the returned Products or sooner if reasonably possible.  In
       the event that (i)  Patheon is unable to replace  the  returned  Products
       within  this  sixty (60) day  period or (ii) such new  Products  are also
       returned or recalled due to a breach by Patheon,  then Client may request
       Patheon to reimburse  Client the purchase  price that Client paid Patheon
       for the affected Products.  In all other circumstances,  customer returns
       shall be made at Client's cost and expense.

4.4    Audits.

       (a)    During the term of this Agreement, Client shall have the right, at
              Client's sole cost and expense,  during normal  business hours and
              upon  reasonable  request and notice,  to inspect the  facilities,
              sanitation procedures and equipment used to manufacture,  test and
              package the Products,  provided,  however,  that there shall be no
              undue interference by Client's representatives with the operations
              at Patheon's facilities.

                                       9
<PAGE>

       (b)    Client  shall have the  right,  upon  prior  reasonable  notice to
              Patheon and during normal business hours, to examine all technical
              records related to the Products (or to examine any portions of any
              technical  records  related to the  Products,  as the case may be)
              kept by Patheon and to request and receive  reasonable  samples of
              raw materials, packaging materials and finished Products.

       (c)    During the term of this  Agreement,  Patheon shall promptly notify
              Client of any inspections by the FDA, or any other federal, state,
              local or foreign  government  agency,  of the facilities where the
              Products are manufactured and packaged and shall thereupon furnish
              Client with copies of all reports,  analyses  and other  documents
              (including  responses  to the FDA)  relating  to such  inspections
              where the  inspections  involve or may involve the  Products,  the
              Components of the Products,  the  manufacture of the Products,  or
              the  premises  used to  process  and  ship the  Products.  If such
              inspections  are  scheduled  or  conducted  with  advance  notice,
              Patheon  shall  so  advise  Client  and  unless  there  is a legal
              prohibition  against  doing so, Client shall have the option to be
              present during the inspections.  Duplicate samples of the Products
              given to government  agencies and  duplicates  of the  photographs
              taken  during the  inspection  shall be  provided  to Client.  Any
              Patheon correspondence  relating to the Products shall be approved
              by Client prior to submission to any government agency.

       (d)    During  the  term of  this  Agreement,  each  party  shall  report
              promptly to the other any  significant  information it may receive
              concerning  any defects,  adverse  reactions and  unexpected  side
              effects, if reasonably believed to be related to the Products.

       (e)    Patheon shall support the annual reporting  requirements of Client
              under the CFR by providing Client with updated  stability data for
              its ongoing studies for the Products.

4.5    Customer   Questions   and   Complaints.   Client  shall  have  the  sole
       responsibility  for  responding to questions and  complaints  from Client
       customers.  Questions  or  complaints  received  by Patheon  from  Client
       customers shall be promptly  referred to Client.  Patheon shall cooperate
       as  required  to allow  Client to  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,  or sooner if reasonably  possible  Patheon shall provide Client
       with all  necessary  information  that  will  enable  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
       breach  by  Patheon  of the  Patheon  Manufacturing  Requirements  or its
       representations  in Section 6.2 hereof,  all costs incurred in respect of
       this Section 4.5 shall be borne by Client.

                                      [***] -  CONFIDENTIAL  TREATMENT REQUESTED

9.2    Purchase  Price  Variances.  The  prices  set out in  Exhibit  B shall be
       subject to adjustment in accordance with the following:

       (a)    If at any time and from time to time, Patheon  determines,  acting
              reasonably  and based on the  forecasts  and Firm Orders  received
              from  Client,  that the  total  annual  projected  volume  for the
              current year relating to a specific  Product will  constitute less
              than  [***]  tablets  ([***]  tablets  in the  year  2000) of that
              Product,   Patheon  shall  be  entitled  to  and  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
              Client a  revised  Exhibit B setting  out the  adjusted  Component
              costs that will be incurred based on the then anticipated  volumes
              for the relevant Product. Upon delivery of such a request, each of
              Client 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 and Client
              shall act in good faith and pay to Patheon the difference  between
              the revised price and the price charged for Products shipped prior
              to the price change;

       (b)    If  at  any  time,   extraordinary  market  conditions  result  in
              Patheon's  cost of Components  being greater or lesser than normal
              forecasted  increases or  decreases,  Patheon shall be entitled to
              and may request an adjustment to the price of any affected Product
              to reflect such increased or decreased  Component  costs.  For the
              purposes of this Subsection 9.2(b), changes greater or lesser than
              normal  forecasted  increases or decreases  shall be considered to
              have  occurred if (i) the cost of a Component is more or less than
              ten per cent  (10%) of the cost at the date  hereof of  Components
              listed in Exhibit B or (ii) the aggregate  cost for all Components
              required to  manufacture  a Product is more or less than 5% of the
              costs at the date hereof for the  Component  set out in Exhibit B.
              To  the  extent  Product  prices  have  been  previously  adjusted
              pursuant  to this  Subsection  9.2(b) to  reflect an  increase  or
              decrease 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 Subsection  9.2(b),  Patheon
              shall  deliver  to  Client a revised  Exhibit  B  setting  out the
              Components,  their  respective  costs at the date  hereof  and the
              adjusted  Component costs that will be incurred as a result of the
              greater or lessor than normal forecasted  increases  together with
              evidence  of  the  cost  change   satisfactory  to  Client  acting
              reasonably.  Upon  delivery of such a request,  each of Client and
              Patheon shall  forthwith use all reasonable  efforts to agree on a
              revised price for each affected  Product that reflects the changed

9.3    Pricing  after  December  31.  2000.  Costing for January 1, 2001 through
       December 31, 2001 will be  negotiated no later than August 31, 2000 based
       on  annual  forecasts  provided  by Sanofi  no later  than July 1,  2000.
       Patheon  acknowledges  Sanofi's  target  price is US $[***] per  thousand
       tablets plus the relevant  inflation  factor assuming a minimum volume of
       [***] tablets  purchased  during 2001.  Patheon also agrees that Sanofi's
       maximum  price is US  $[***]  per  thousand  tablets  plus  the  relevant
       inflation  factor based on [***] tablets annual volume and subject to the
       other terms and conditions of this Agreement. The prices for each Product
       during each  additional  year  subsequent  to December 31, 2001 that this
       Agreement  remains in force shall be agreed to between the parties  prior
       to the  commencement  of each such year.  In such  circumstances,  Client
       shall provide  Patheon with the yearly volume  forecasts  contemplated by
       Section 3.2 at least one hundred and twenty (120) days prior to the first
       day of each such additional  year.  Based on those  projections,  Patheon
       will  deliver to Client,  no later than sixty (60) days after  receipt of
       such  yearly  forecast,  a  revised  Exhibit B and such  other  budgetary
       pricing  information  as it deems  necessary  to  allow  the  parties  to
       effectively  settle all prices for the  relevant  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.  The relevant
       inflation  factor is the Consumer Price Index for All Urban  Consumers as
       published by the Bureau of Labor  Statistics  of the U.S.  Department  of
       Labour, for the most recent 12 month period.

9.4    Tooling Costs.  Sanofi shall reimburse  Patheon promptly upon request for
       any costs related to tablet press tooling and printing press change parts
       specific to the Prenate logo required for the production of the Products.
       These  charges  are to be  approved by Sanofi  prior to  incurring  these
       costs.

9.5    Rebate. If Patheon does not during the term of this Agreement  purchase a
       high speed double sided tablet printing  machine for use in producing the
       Products, Patheon shall rebate to Client the US$40,000 discount described
       in Patheon's  letter to Client dated December 9, 1998 related to the cost
       of the analytical method validation work for this project, which discount
       Client waived to support the printer acquisition.

10.0   MISCELLANEOUS

10.1   Product  Discontinuation.  During  the  term  of  this  Agreement  or any
       extension, Client shall provide at least six (6) months advance notice if
       it intends to no longer  order a Product  due to its  discontinuance.  In
       such event, Client shall have the right to terminate this Agreement as it
       relates to the discontinued Product and shall, subject to 5.3(d), have no
       further liability hereunder in respect of such discontinued Product.

                                       15
<PAGE>

10.2   Compliance  with Laws.  Each party,  in connection  with its  performance
       under this  Agreement,  shall  comply with all  applicable  laws,  rules,
       regulations,  and orders  including  maintaining  all insurance  coverage
       required by state, federal, provincial or other applicable laws.

10.3   Permits.  Patheon  shall,  at its own  expense,  obtain and  maintain the
       necessary  permits  required  for the  manufacture,  packaging,  testing,
       export and supply of the  Products,  provided  that Patheon  shall not be
       responsible for obtaining or maintaining any permits or other  regulatory
       approvals in respect of the Products or the  Specifications,  which shall
       be the sole responsibility of Client.

10.4   Trademark.  Client and Patheon hereby acknowledge that neither party has,
       nor shall it acquire, any interest in any of the other party's trademarks
       or trade names  unless  otherwise  expressly  agreed to in  writing.  The
       parties  agree not to use any trademark or trade name of the other party,
       except as specifically authorized by the other party.

10.5   Reports.  Patheon will on an annual basis supply product data,  including
       release test results,  complaint  test results,  all  investigations  (in
       manufacturing,   testing  and  storage),   and  the  like,  which  Client
       reasonably requires in order to complete the Annual Product Review report
       that is required to be filed by Client with the FDA.

10.6   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 of not less than  $2,000,000 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 effective date, the expiration date and the limits of liability.  The
       insurance  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,  subject to the insurer's agreement to so state
       on the  certificate.  Each party shall cause its insurance policy to name
       the other party hereto as an  additional  insured and a loss payee.  Each
       party's  general  liability  insurance  policy shall  contain a waiver of
       subrogation  rights  which that party's  insurer(s)  may have against the
       other party.

10.7   Independent  Contractors.  The parties shall be deemed to be  independent
       contractors,  and this Agreement shall not be construed to create between
       Pathcon  and  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.

                                       16
<PAGE>

10.8   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 or any other provision of this Agreement.

10.9   Assignment. Patheon may not assign this Agreement or any of its rights or
       obligations  hereunder  except with the written  consent of Client,  such
       consent not to be unreasonably withheld. Client may assign this Agreement
       or any of its  rights or  obligations  hereunder  without  approval  from
       Patheon  provided  that the  proposed  assignee is  credit-worthy  in the
       opinion of Patheon  acting  reasonably,  Client shall give prior  written
       notice of any  assignment to Patheon and any assignee  shall  covenant in
       writing  with  Patheon (and Patheon  shall be  reasonable  in  connection
       therewith)  to be bound by the terms of this  Agreement.  Notwithstanding
       the foregoing  provisions  of this Section 10.9,  either party may assign
       this  Agreement  to any of its  affiliates  or to a  successor  to all or
       substantially  all of its  business  and,  in the case of Client,  all or
       substantially all of the business related to the Products covered by this
       Agreement,  provided that the proposed  assignee is  credit-worthy in the
       opinion  of the  non-assigning  party  acting  reasonably  and that  such
       assignee  executes  an  agreement  with the  non-assigning  party  hereto
       whereby it agrees to be bound hereunder.

10.10  Force  Majeure.  Neither party shall be liable for the failure to perform
       its  obligations  under this Agreement if such failure is occasioned by a
       contingency beyond such party's reasonable  control,  including,  but not
       limited to, strikes or other labour disturbances,  lockouts, riots, wars,
       fires,  floods or storms. A party claiming a right to excused performance
       under this  Section  10.10  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. Such other party shall have the right to receive alternative
       arrangements  during the period of the force majeure and, after 3 months,
       shall have the right to terminate this Agreement.

10.11  Development Work.

       (a)    Subject to the terms set out in this Section 10.11,  Patheon shall
              perform  certain  research  and  development  work  related to the
              Products  listed  at the date  hereof  on  Exhibit  A or any other
              Prenate line of products on an exclusive  basis for Client or such
              other  products  as Client  shall from time to time  require  (the
              "Development   Work").   The  Development  Work  may  include  the
              following:

              (i)    process development;
              (ii)   formulation development (present and future formulations);
              (iii)  analytical method development;
              (iv)   analytical method validation and qualification;
              (v)    process validation;
              (vi)   stability studies;
              (vii)  packaging; and

                                       17
<PAGE>
                                        [***] - CONFIDENTIAL TREATMENT REQUESTED

              (viii)   documentation (such as documentation for validation
                       and stability protocols, batch records and
                       monographs, etc.)

       (b)    The parties  shall  endeavour to jointly  define in good faith the
              specific  Development  Work  to be  performed,  the  scope  of the
              project,  the  price  (subject  to (d)  below)  to be paid and the
              associated  timelines  for such  activities.  If the  foregoing is
              agreed to by the  parties,  it shall be reflected in an exhibit to
              this Agreement.

       (c)    If Client,  in its sole  discretion,  decides to  commercialize  a
              product   related  to   Development   Work  performed  by  Patheon
              hereunder,  Client will notify Patheon thereof.  Patheon will have
              60 days  from the  receipt  of such  notice  to  submit  to Client
              pricing for the  commercial  production  of the relevant  product.
              Promptly  thereafter the parties shall commence  negotiations with
              respect  to price and any  other  remaining  terms and  conditions
              (collectively,  "Terms and  Conditions").  If the parties reach an
              agreement on the Terms and  Conditions of commercial  supply,  the
              product will be added to this Agreement  pursuant to section 10.12
              and such  additional  product  shall be  governed  by the  general
              conditions  hereof with  any  special  terms  (including,  without
              limitation,  price) governed by an addendum hereto. If the parties
              are  unable to reach an  agreement  on such  Terms and  Conditions
              within 60 days after the  commencement of the  negotiations,  then
              Client may terminate  negotiations and thereafter Client may enter
              into an agreement with any third party for  the  commercialization
              of the product.  Patheon will only be entitled to bid on providing
              commercial  production  services if it has adequate production and
              technical   capacity  to  meet  Client's  standards  and  timeline
              requirements, and can satisfy all applicable regulatory standards.

       (d)    Client  shall pay Patheon for the  Development  Work at  Patheon's
              agreed rates stated in U.S. dollars, which are at the date hereof:

                o        Formulation Scientist: $[***]
                o        Formulation Technician: $[***]
                o        Analytical Chemist: $[***]
                o        Formulation Chemist: $[***]
                o        Project Manager: $[***]
                o        Documentation Specialist: $[***]

              It is understood by the parties that the price for the Development
              Work for Prenate  products in tablet form shall be calculated in a
              manner  consistent with the development work previously  performed
              by Patheon in connection with the Prenate  Products in tablet form
              covered under this Agreement and Patheon agrees that the foregoing
              rates  shall  remain  unchanged  during  the  first  year  of this
              Agreement.  Thereafter  such  rates  shall  not  exceed  Patheon's
              standard rates for such services.  Such development work, together
              with the related pricing, is described in Exhibit C hereto.

                                       18

       (e)    All information, data, results, inventions or discoveries (whether
              patentable  or  not),   formulations,   manufacturing   processes,
              reports,   records   (including   batch  records),   and  formulas
              (collectively,  "Data") related to the  Development  Work shall be
              the property of the Client, and Patheon shall assign to Client any
              interests it may have in such Data, including any copyright rights
              therein.   Patheon   shall   treat   such  Data  as   Confidential

              patentable  or  not),   formulations,   manufacturing   processes,
              reports,   records   (including   batch  records),   and  formulas
              (collectively,  "Data")  related to development  work performed by
              Patheon for Client  prior to the date of this  Agreement  shall be
              the  property  of the  Client,  and  Patheon  shall also assign to
              Client  any  interests  it may have in such  Data,  including  any
              copyright  rights  therein.  Patheon  shall  treat  such  Data  as
              Confidential  Information.  For the  avoidance  of doubt,  Patheon
              hereby   acknowledges   and   agrees   that   the   Products   and
              Specifications  set  forth  in  Exhibits  A,  A-1  and C  are  the
              exclusive property of the Client.

10.12  New Products. The parties covenant and agree that 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.

10.13  Debarment.  Patheon  represents  and warrants that it and its  employees,
       affiliates and agents have never been (i) debarred or (ii) convicted of a
       crime for which a person can be  debarred,  under  Section  306(a) of the
       Generic Drug  Enforcement  Act of 1992 (Section 306 (a) or (b)).  Patheon
       represents  and  warrants  that it has never been and, to the best of its
       knowledge after due inquiry, none of its employees,  affiliates or agents
       has ever been (1)  threatened  to be debarred or (2) indicted for a crime
       or otherwise engaged in conduct for which a person can be debarred, under
       Section 306(a) or (b). Patheon agrees that it will promptly notify Client
       upon learning of any such debarment, conviction, threat or indictment.

       required or permitted  hereunder  shall be sufficient if made or given to
       the other party by personal delivery,  by telecopier  communication or by

Commercial Costing Terms and Conditions:

1.     Stability testing,  validation costs and additional development costs are
       not included in the above commercial pricing.

2.     Costs for final blister packaging are not included.

3.     Prices for September, 1999 through May 31, 2000 arc based on a minimum of
       [***]  tablets  shipped to Sanofi  during this time period  (inclusive of
       Product  shipped  prior to execution of this  Agreement).  Prices for any
       quantity  shipped  above this [***] tablet  threshold  during this period
       will not be subject to review.

4.     Prices for June 1, 2000 through  December 31, 2000 are  conditional  on a
       minimum annual quantity of [***] tablets forecasted for the calendar year
       2000 provided that such price shall not become  available until after (i)
       June 1, 2000 and (ii)  [***]  tablets  in  commercial  batches of Product
       having  been  shipped  during  1999  through  2000.  The price for volume
       between  [***] and [***]  tablets  shipped  during  calendar year 2000 is
       $[***].  Any total  quantity  shipped  below [***] in calendar  2000 will
       result in a change in pricing  for the  entire  shipped  quantity  during
       calendar year 2000. If [***] tablets are not shipped  between  September,
       1999 and May 31, 2000 then for the  remainder  of the year 2000 the price
       of [***] remains in effect until [***]  tablets have been  shipped.  Once
       the [***]  tablets  volume price is achieved,  there will be no change in
       prices for volume greater than [***] tablets.

5.     Sanofi  estimates  an  incremental   US$[***]  for  use  in  new  product
       development  for 2000 but such  estimate  is not a  condition  of pricing
       above.

       For  greater  clarity,  examples  of  the  above  pricing  conditions  in
operation are set out below.

1.     If Client does not purchase  [***]  tablets for delivery by 5/31/00,  the
       $[***] price  remains in effect for  calendar  year 2000 as long as [***]
       volume has not been reached.

2.     If shipments  are greater  than [***]  tablets by  5/31/2000,  the $[***]
       price applies to the quantity in excess of [***] provided that the $[***]
       price is not available before 5/31/00. E.g. [***] tablets or more shipped
       by 5/31/00, the price for all [***] or more is $[***].

3.     If a minimum of [***]  tablets  are  shipped by 5/31/00 so that client is
       entitled  to  reduced  price of $[***] and then only  [***]  tablets  are
       shipped from 6/1/00 to  12/31/00,  the $[***] price will be in effect for
       calendar 2000 and the  difference  between  $[***] and $[***] price to be
       reimbursed by Sanofi to Patheon at the end of the year.

       e.g.  $[***] shipped in 1999,  [***] shipped between Jan-May 31, 2000 and
       only [***] between June-Dec.  31, 2000 results in volume of [***] tablets
       for  calendar  year 2000 and Client  must  reimburse  using  formula  for
       reimbursement: (Actual volume - [***].

4.     If calendar 2000 volumes are less than [***] tablets then Section  9.2(a)
       is in effect  and price to be  negotiated  in good  faith and  difference
       reimbursed to Patheon.

5.     If in calendar  year 2000 volumes are greater than [***] tablets then the
       price is $[***] for excess of volume over the first [***] tablets  ([***]
       includes shipments made beginning September 1999), provided that there is
       no retroactive  price decrease for any volume of Product shipped prior to
       June 1, 2000.

                     AMENDED AND RESTATED CUSTOMER AGREEMENT

            THIS AMENDED AND RESTATED CUSTOMER AGREEMENT (this "Agreement"),
made as of the 22nd day of June, 2000, by and between DEAN WITTER PORTFOLIO
STRATEGY FUND L.P., a Delaware limited partnership (the "Customer"), and DEAN
WITTER REYNOLDS INC., a Delaware corporation ("DWR");

                              W I T N E S S E T H :
                              - - - - - - - - - -

            WHEREAS, the Customer was organized pursuant to a Certificate of
Limited Partnership filed in the office of the Secretary of State of the State
of Delaware on August 28, 1990, as amended, and a Limited Partnership Agreement
dated as of August 28, 1990, and amended and restated as of July 1, 1997,
between Demeter Management Corporation, a Delaware corporation ("Demeter"),
acting as general partner (in such capacity, the "General Partner"), and the
limited partners of the Customer ("Limited Partners") to trade, buy, sell,
spread or otherwise acquire, hold, or dispose of commodities (including, but not
limited, to foreign currencies, mortgage-backed securities, money market
instruments, financial instruments, and any other securities or items which are,
or may become, the subject of futures contract trading), domestic and foreign
commodity futures contracts, commodity forward contracts, foreign exchange
commitments, options on physical commodities and on futures contracts, spot
(cash) commodities and currencies, and any rights pertaining thereto
(hereinafter referred to collectively as "futures interests") and securities
(such as United States Treasury securities) approved by the Commodity Futures
Trading Commission (the "CFTC") for investment of customer funds, and to engage
in all activities incident thereto;

            WHEREAS, the Customer (which is a commodity pool) and the General
Partner (which is a registered commodity pool operator) have entered into a
management agreement (the "Management Agreement") with a certain trading advisor
(the "Trading Advisor"), which provides that the Trading Advisor has authority
and responsibility, except in certain limited situations, to direct the
investment and reinvestment of the assets of the Customer in futures interests
under the terms set forth in the Management Agreement;

            WHEREAS, the Customer and DWR entered into that certain Amended and
Restated Customer Agreement dated as of December 1, 1997 (the "Customer
Agreement"), whereby DWR agreed to perform non-clearing futures interests
brokerage and certain other services for the Customer; and

            WHEREAS, the Customer and DWR wish to amend and restate the Customer
Agreement to set forth the terms and conditions upon which DWR will continue to
perform certain non-clearing futures interests brokerage and certain other
services for the Customer;

            NOW, THEREFORE, the parties hereto hereby agree as follows:

            1. Definitions. All capitalized terms not defined herein shall have
the meaning given to them in the Customer's most recent prospectus as filed with
the Securities and Exchange Commission (the "Prospectus") relating to the
offering of units of limited partnership interest of the Customer (the "Units")
and in any amendment or supplement to the Prospectus.

            2. Duties of DWR. DWR agrees to act as a non-clearing commodity
broker for the Customer and introduce the Customer's account to Morgan Stanley &
Co. Incorporated ("MS & Co.") and Morgan Stanley & Co. International Limited
("MSIL") for execution and clearing of futures interests transactions on behalf
of the Customer in accordance with instructions provided by the Trading Advisor,
and the Customer agrees to retain DWR as a non-clearing commodity broker for the
term of this Agreement.

            DWR agrees to furnish to the Customer as soon as practicable all of
the information from time to time in its possession which Demeter, as the
general partner of the Customer, is required to furnish to the Limited Partners
pursuant to the Limited Partnership Agreement as from time to time in effect and
as required by applicable law, rules, or regulations and to perform such other
services for the Customer as are set forth herein and in the Prospectus.

            3. Obligations and Expenses.

               (a) Except as otherwise set forth herein, the Customer, and not
DWR, shall be responsible for all taxes, management and incentive fees to the
Trading Advisor, brokerage commissions to DWR, and all extraordinary expenses
incurred by it. In addition, the Customer, and not DWR, shall pay the charges of
MS & Co. and MSIL for executing and clearing the Customer's futures interests
trades (as described in paragraph 5(b) below).

               (b) The Customer will pay its ordinary administrative expenses,
subject to a cap of 0.25% per year of the Customer's average month-end Net
Assets, including expenses for services provided by third parties selected by
the General Partner and reimbursement of all out-of-pocket expenses incurred by
such persons and by the General Partner and its affiliates in providing services
to the Customer. Such expenses shall include legal, accounting and auditing
expenses (including expenses incurred in preparing reports and tax information
to Limited Partners and regulatory authorities and expenses for specialized
administrative services), printing and duplication expenses, mailing expenses,
and filing fees. The General Partner or its affiliates shall pay any ordinary
administrative expenses which exceed the cap.

            4. Agreement Nonexclusive. DWR shall be free to render services of
the nature to be rendered to the Customer hereunder to other persons or entities
in addition to the Customer, and the parties acknowledge that DWR may render
such services to additional entities similar in nature to the Customer,
including other partnerships organized with Demeter as their general partner. It
is expressly understood and agreed that this Agreement is nonexclusive and that
the Customer has no obligation to execute any or all of its trades for futures
interests through DWR. The parties acknowledge that the Customer may utilize
such other broker or brokers as Demeter may direct from time to time. The
Customer's utilization of an additional commodity broker shall neither terminate
this Agreement nor modify in any regard the respective rights and obligations of
the Customer and DWR hereunder.

            5. (a) Compensation of DWR. The Customer will pay brokerage
commissions to DWR at a roundturn rate (but charged on a half-turn basis) of 80%
of DWR's published non-member rates for speculative accounts (which covers both
the taking and liquidation of a position), and substantially equivalent rates
for currency forward contract transactions in the forward contract and interbank
markets.

            The Customer will pay DWR brokerage commissions for currency forward
contract transactions at rates established with reference to the brokerage
commission rate charged on exchange-traded currency futures contracts. DWR may
from time to time adjust the United States dollar size of currency forward
contracts so that the brokerage commission rate charged on such contracts will
approximate the rate charged on exchange-traded currency futures contracts of
similar United States dollar value. DWR shall also charge the Partnership
brokerage commissions for rollovers of forward contract positions.

               (b) Compensation of MS & Co. and MSIL. The Customer will pay
certain charges of MS & Co. and MSIL for executing and clearing trades for the
Customer pursuant to those certain Customer Agreements dated as of May 1, 2000,
among the Customer, MS & Co. and DWR, and between the Customer and MSIL. In
addition, DWR shall pay MS & Co. certain charges with respect to the execution
and clearance of trades for the Customer as agreed from time to time between DWR
and MS & Co. For purposes of clarity, the mark-up, spread, or other profit of MS
& Co. included as a part of the transaction price on each foreign currency
forward contract trade executed with MS & Co. pursuant to the Foreign Exchange
and Options Master Agreement between MS & Co. and the Customer is separate from
the fees paid to DWR or MS & Co. pursuant to either this Agreement or the
Customer Agreement among the Customer, MS & Co. and DWR.

               (c) Notwithstanding the foregoing, brokerage commissions,
together with transaction fees and costs including those paid by the Customer to
MS & Co. and MSIL, with respect to the Trading Advisor's allocated Net Assets
will be capped at 13/20 of 1% per month (in the event the Trading Advisor
employs multiple trading systems in trading on behalf of the Customer, the
foregoing cap is applied on a per trading system basis) of the Customer's Net
Assets allocated to such Trading Advisor or trading system as of the last day of
each month (a maximum 7.8% annual rate). In addition, the aggregate of (i)
brokerage commissions and transaction fees and costs payable by the Customer,
and (ii) net excess interest and compensating balance benefits to DWR (after
crediting the Customer with interest) shall not exceed 14% annually of the
Customer's average month-end Net Assets during each calendar year.

               (d) Any brokerage commissions, and transaction fees and costs in
excess of such caps shall be borne or paid by DWR or an affiliate and shall not
be reimbursed by the Customer. The foregoing caps may not be increased except as
permitted in the Customer's Limited Partnership Agreement, as amended from time
to time.

            6. Investment Discretion. The parties recognize that DWR shall have
no authority to direct the futures interests investments to be made for the
Customer's account. However, the parties agree that DWR, and not the Trading
Advisor, shall have the authority and responsibility with regard to the
investment, maintenance, and management of the Customer's assets that are held
in segregated or secured accounts, as provided in Section 7 hereof.

            7. Investment of Customer Funds. The Customer shall deposit its
assets in accounts with DWR. The Customer's assets deposited with DWR will be
segregated or secured in accordance with the Commodity Exchange Act and CFTC
regulations. DWR will credit the Customer with interest income at month-end as
if 80% of the Customer's average daily Net Assets for the month were invested at
the rate earned by DWR on its U.S. Treasury Bill investments with customer
segregated funds. All of such funds will be available for margin for the
Customer's trading. For the purpose of such interest payments, Net Assets will
not include monies due to the Customer on or with respect to forward contracts
and other futures interests but not actually received by it from banks, brokers,
dealers and other persons. The Customer understands that it will not receive any
other interest income on its assets and that DWR will receive interest income
from MS & Co. and MSIL, as agreed from time to time by DWR, MS & Co. and MSIL,
on the Customer's assets deposited as margin with MS & Co. and MSIL. The
Customer's funds will either be invested along with other customer segregated
and secured funds of DWR or held in non-interest bearing bank accounts. The
Customer's assets held by DWR may be used solely as margin for the Customer's
trading.

            Ownership of the right to receive interest on the Customer's assets
pursuant to the preceding paragraph shall be reflected and maintained and may be
transferred only on the books and records of DWR. Any purported transfer of such
ownership shall not be effective or recognized until such transfer shall have
been recorded on the books and records of DWR.

            8. Standard of Liability and Indemnity. Subject to Section 2 hereof,
DWR and its affiliates (as defined below) shall not be liable to the Customer,
the General Partner or Limited Partners, or any of its or their respective
successors or assigns, for any act, omission, conduct, or activity undertaken by
or on behalf of the Customer pursuant to this Agreement which DWR determines, in
good faith, to be in the best interests of the Customer, unless such act,
omission, conduct, or activity by DWR or its affiliates constituted misconduct
or negligence.

            The Customer shall indemnify, defend and hold harmless DWR and its
affiliates from and against any loss, liability, damage, cost or expense
(including attorneys' and accountants' fees and expenses incurred in the defense
of any demands, claims, or lawsuits) actually and reasonably incurred arising
from any act, omission, conduct or activity undertaken by DWR on behalf of the
Customer pursuant to this Agreement, including, without limitation, any demands,
claims or lawsuits initiated by a Limited Partner (or assignee thereof),
provided that (i) DWR has determined, in good faith, that the act, omission,
conduct, or activity giving rise to the claim for indemnification was in the
best interests of the Customer, and (ii) the act, omission, conduct, or activity
that was the basis for such loss, liability, damage, cost, or expense was not
the result of misconduct or negligence. Notwithstanding anything to the contrary
contained in the foregoing, neither DWR nor any of its affiliates shall be
indemnified by the Customer for any losses, liabilities, or expenses arising
from or out of an alleged violation of federal or state securities laws unless
(a) there has been a successful adjudication on the merits of each count
involving alleged securities law violations as to the particular indemnitee, or
(b) such claims have been dismissed with prejudice on the merits by a court of
competent jurisdiction as to the particular indemnitee, or (c) a court of
competent jurisdiction approves a settlement of the claims against the
particular indemnitee and finds that indemnification of the settlement and
related costs should be made, provided, with regard to such court approval, the
indemnitee must apprise the court of the position of the SEC, and the positions
of the respective securities administrators of Massachusetts, Missouri,
Tennessee and/or those other states and jurisdictions in which the plaintiffs
claim they were offered or sold Units, with respect to indemnification for
securities laws violations before seeking court approval for indemnification.
Furthermore, in any action or proceeding brought by a Limited Partner in the
right of the Customer to which DWR or any affiliate thereof is a party
defendant, any such person shall be indemnified only to the extent and subject
to the conditions specified in the Delaware Revised Uniform Limited Partnership
Act, as amended, and this Section 8. The Customer shall make advances to DWR or
its affiliates hereunder only if: (i) the demand, claim, lawsuit, or legal
action relates to the performance of duties or services by such persons to the
Customer; (ii) such demand, claim, lawsuit, or legal action is not initiated by
a Limited Partner; and (iii) such advances are repaid, with interest at the
legal rate under Delaware law, if the person receiving such advance is
ultimately found not to be entitled to indemnification hereunder.

            DWR shall indemnify, defend and hold harmless the Customer and its
successors or assigns from and against any losses, liabilities, damages, costs,
or expenses (including in connection with the defense or settlement of claims;
provided DWR has approved such settlement) incurred as a result of the
activities of DWR or its affiliates, provided, further, that the act, omission,
conduct, or activity giving rise to the claim for indemnification was the result
of bad faith, misconduct or negligence.

            The indemnities provided in this Section 8 by the Customer to DWR
and its affiliates shall be inapplicable in the event of any losses,
liabilities, damages, costs, or expenses arising out of, or based upon, any
material breach of any warranty, covenant, or agreement of DWR contained in this
Agreement to the extent caused by such breach. Likewise, the indemnities
provided in this Section 8 by DWR to the Customer and any of its successors and
assigns shall be inapplicable in the event of any losses, liabilities, damages,
costs, or expenses arising out of, or based upon, any material breach of any
warranty, covenant, or agreement of the Customer contained in this Agreement to
the extent caused by such breach.

            As used in this Section 8, the term "affiliate" of DWR shall mean:
(i) any natural person, partnership, corporation, association, or other legal
entity directly or indirectly owning, controlling, or holding with power to vote
10% or more of the outstanding voting securities of DWR; (ii) any partnership,
corporation, association, or other legal entity 10% or more of whose outstanding
voting securities are directly or indirectly owned, controlled, or held with
power to vote by DWR; (iii) any natural person, partnership, corporation,
association, or other legal entity directly or indirectly controlling,
controlled by, or under common control with, DWR; or (iv) any officer or
director of DWR. Notwithstanding the foregoing, "affiliates" for purposes of
this Section 8 shall include only those persons acting on behalf of DWR within
the scope of the authority of DWR, as set forth in this Agreement.

            9. Term. This Agreement shall continue in effect until terminated by

FUTURES CUSTOMER AGREEMENT

In consideration of the acceptance by Dean Witter Reynolds Inc. ("DWR") of one
or more accounts of the undersigned ("Customer") (if more than one account is
carried by DWR, all are covered by this Agreement and are referred to
collectively as the "Account") and DWR's agreement to act as Customer's broker
for the execution, clearance and/or carrying of transactions for the purchase
and sale of commodity interests, including commodities, commodity futures
contracts and commodity options, Customer agrees as follows:

1.    APPLICABLE RULES AND REGULATIONS - The Account and each transaction
      therein shall be subject to the terms of this Agreement and to (a) all
      applicable laws and the regulations, rules and orders (collectively
      "regulations") of all regulatory and self-regulatory organizations having
      jurisdiction and (b) the constitution, by-laws, rules, regulations,
      orders, resolutions, interpretations and customs and usages (collectively
      "rules") of the market and any associated clearing organization (each an
      "exchange") on or subject to the rules of which such transaction is
      executed and/or cleared. The reference in the preceding sentence to
      exchange rules is solely for DWR's protection and DWR's failure to comply
      therewith shall not constitute a breach of this Agreement or relieve
      Customer of any obligation or responsibility under this Agreement. DWR
      shall not be liable to Customer as a result of any action by DWR, its
      officers, directors, employees or agents to comply with any rule or
      regulation.

2.    PAYMENTS TO DWR - Customer agrees to pay to DWR immediately on request (a)
      commissions, fees and service charges as are in effect from time to time
      together with all applicable regulatory and self-regulatory organization
      and exchange fees, charges and taxes; (b) the amount of any debit balance
      or any other liability that may result from transactions executed for the
      account; and (c) interest on such debit balance or liability at the
      prevailing rate charged by DWR at the time such debit balance or liability
      arises and service charges on any such debit balance or liability together
      with any reasonable costs and attorney's fees incurred in collecting any
      such debit balance or liability. Customer acknowledges that DWR may charge
      commissions at other rates to other customers.

3.    CUSTOMER'S DUTY TO MAINTAIN ADEQUATE MARGIN - Customer shall at all times
      and without prior notice or demand from DWR maintain adequate margins in
      the account so as continually to meet the original and maintenance margin
      requirements established by DWR for Customer. DWR may change such
      requirements from time to time at DWR's discretion. Such margin
      requirements may exceed the margin requirements set by any exchange or
      other regulatory authority and may vary from DWR's requirements for other
      customers. Customer agrees, when so requested, immediately to wire
      transfer margin funds and to furnish DWR with names of bank officers for
      immediate verification of such transfers. Customer acknowledges and agrees
      that DWR may receive and retain as its own any interest, increment,
      profit, gain or benefit directly or indirectly, accruing from any of the
      funds DWR receives from Customer.

4.    DELIVERY; OPTION EXERCISE

      (a)   Customer acknowledges that the making or accepting of delivery
            pursuant to a futures contract may involve a much higher degree of
            risk than liquidating a position by offset. DWR has no control over
            and makes no warranty with respect to grade, quality or tolerances
            of any commodity delivered in fulfillment of a contract.

      (b)   Customer agrees to give DWR timely notice and immediately on request
            to inform DWR if Customer intends to make or take delivery under a
            futures contract or to exercise an option contract. If so requested,
            Customer shall provide DWR with satisfactory assurances that
            Customer can fulfill Customer's obligation to make or take delivery
            under any contract. Customer shall furnish DWR with property
            deliverable by it under any contract in accordance with DWR's
            instructions.

      (c)   DWR shall not have any obligation to exercise any long option
            contract unless Customer has furnished DWR with timely exercise
            instructions and sufficient initial margin with respect to each
            underlying futures contract.

5.    FOREIGN CURRENCY - If DWR enters into any transaction for Customer
      effected in a currency other than U.S. dollars: (a) any profit or loss
      caused by changes in the rate of exchange for such currency shall be for
      Customer's account and risk and (b) unless another currency is designated
      in DWR's confirmation of such transaction, all margin for such transaction
      and the profit or loss on the liquidation of such transaction shall be in
      U.S. dollars at a rate of exchange determined by DWR in its discretion on
      the basis of then prevailing market rates of exchange for such foreign
      currency.

6.    DWR MAY LIMIT POSITIONS HELD - Customer agrees that DWR, at its
      discretion, may limit the number of open positions (net or gross) which
      Customer may execute, clear and/or carry with or acquire through it.
      Customer agrees (a) not to make any trade which would have the effect of
      exceeding such limits, (b) that DWR may require Customer to reduce open
      positions carried with DWR and (c) that DWR may refuse to accept orders to
      establish new positions. DWR may impose and enforce such limits, reduction
      or refusal whether or not they are required by applicable law, regulations
      or rules. Customer shall comply with all position limits established by
      any regulatory or self-regulatory organization or any exchange. In
      addition, Customer agrees to notify DWR promptly if customer is required
      to file position reports with any regulatory or self-regulatory
      organization or with any exchange.

7.    NO WARRANTY AS TO INFORMATION OR RECOMMENDATION - Customer acknowledges
      that:

      (a)   Any market recommendations and information DWR may communicate to
            Customer, although based upon information obtained from sources
            believed by DWR to be reliable, may be incomplete and not subject to
            verification;

      (b)   DWR makes no representation, warranty or guarantee as to, and shall
            not be responsible for, the accuracy or completeness of any
            information or trading recommendation furnished to Customer;

      (c)   recommendations to Customer as to any particular transaction at any
            given time may differ among DWR's personnel due to diversity in
            analysis of fundamental and technical factors and may vary from any
            standard recommendation made by DWR in its market letters or
            otherwise; and

      (d)   DWR has no obligation or responsibility to update any market
            recommendations or information it communicates to Customer.

            Customer understands that DWR and its officers, directors,
affiliates, stockholders, representatives or associated persons may have
positions in and may intend to buy or sell commodity interests which are the
subject of market recommendations furnished to Customer, and that the market
positions of DWR or any such officer, director, affiliate, stockholder,
representative or associated person may or may not be consistent with the
recommendations furnished to Customer by DWR.

8.    LIMITS ON DWR DUTIES; LIABILITY - Customer agrees:

      (a)   that DWR has no duty to apprise Customer of news or of the value of
            any commodity interests or collateral pledged or in any way to
            advise Customer with respect to the market;

      (b)   that the commissions which DWR receives are consideration solely for
            the execution, reporting and carrying of Customer's trades;

      (c)   that if Customer has authorized any third party or parties to place
            orders or effect transactions on behalf of Customer in any Account,
            each such party has been selected by Customer based on its own
            evaluation and assessment of such party and that such party is
            solely the agent of Customer, and if any such party allocates
            commodity interests among its customers, Customer has reviewed each
            such party's commodity interest allocation system, has satisfied
            itself that such allocation system is fair and will seek recovery
            solely from such party to recover any damages sustained by Customer
            as the result of any allocation made by such party; and

      (d)   to waive any and all claims, rights or causes of action which
            Customer has or may have against DWR or its officers, employees and
            agents (i) arising in whole or in part, directly or indirectly, out
            of any act or omission of any person, whether or not legally deemed
            an agent of DWR, who refers or introduces Customer to DWR or places
            orders for Customer and (ii) for any punitive damages and to limit
            any claims arising out of this Agreement or the Account to
            Customer's direct out-of-pocket damages.

9.    EXTRAORDINARY EVENTS - Customer shall have no claim against DWR for any
      loss, damage, liability, cost, charge, expense, penalty, fine or tax
      caused directly or indirectly by (a) governmental, court, exchange,
      regulatory or self-regulatory organization restrictions, regulations,
      rules, decisions or orders, (b) suspension or termination of trading, (c)
      war or civil or labor disturbance, (d) delay or inaccuracy in the
      transmission or reporting of orders due to a breakdown or failure of
      computer services, transmission or communication facilities, (e) the
      failure or delay by any exchange to enforce its rules or to pay to DWR any
      margin due in respect of Customer's Account, (f) the failure or delay by
      any bank, trust company, clearing organization or other person which,
      pursuant to applicable exchange rules, is holding Customer funds,
      securities or other property to pay or deliver the same to DWR or (g) any
      other cause or causes beyond DWR's control.

10.   INDEMNIFICATION OF DWR - Customer agrees to indemnify, defend and hold
      harmless DWR and its officers, employees and agents from and against any
      loss, cost, claim, damage (including any consequential cost, loss or
      damage), liability or expense (including reasonable attorneys' fees) and
      any fine, sanction or penalty made or imposed by any regulatory or
      self-regulatory authority or any exchange as the result, directly or
      indirectly, of:

      (a)   Customer's failure or refusal to comply with any provision of this
            Agreement or perform any obligation on its part to be performed
            pursuant to this Agreement; and

      (b)   Customer's failure to timely deliver any security, commodity or
            other property previously sold by DWR on Customer's behalf.

11    NOTICES; TRANSMITTALS - DWR shall transmit all communications to Customer
      at Customer's address, telefax or telephone number set forth in the
      accompanying Futures Account Application or to such other address as
      Customer may hereafter direct in writing. Customer shall transmit all
      communications to DWR (except routine inquiries concerning the Account) to
      130 Liberty Street, New York, NY 10006, Attention: Futures Compliance
      Officer. All payments and deliveries to DWR shall be made as instructed by
      DWR from time to time and shall be deemed received only when actually
      received by DWR.

12.   CONFIRMATION CONCLUSIVE - Confirmation of trades and any other notices
      sent to Customer shall be conclusive and binding on Customer unless
      Customer or Customer's agent notifies DWR to the contrary (a) in the case
      of an oral report, orally at the time received by Customer or its agent or
      (b) in the case of a written report or notice, in writing prior to opening
      of trading on the business day next following receipt of the report. In
      addition, if Customer has not received a written confirmation that a
      commodity interest transaction has been executed within three business
      days after Customer has placed an order with DWR to effect such
      transaction, and has been informed or believes that such order has been or
      should have been executed, then Customer immediately shall notify DWR
      thereof. Absent such notice, Customer conclusively shall be deemed
      estopped to object and to have waived any such objection to the failure to
      execute or cause to be executed such transaction. Anything in this Section
      12 withstanding, neither Customer nor DWR shall be bound by any
      transaction or price reported in error.

13.   SECURITY INTEREST - All money and property ("collateral") now or at any
      future time held in Customer's Account, or otherwise held by DWR for
      Customer, is subject to a security interest in DWR's favor to secure any
      indebtedness at any time owing to it by Customer. DWR, in its discretion,
      may liquidate any collateral to satisfy any margin or Account deficiencies
      or to transfer the collateral to the general ledger account of DWR.

14.   TRANSFER OF FUNDS - At any time and from time to time and without prior
      notice to Customer, DWR may transfer from one account to another account
      in which Customer has any interest, such excess funds, equities,
      securities or other property as in DWR's judgment may be required for
      margin, or to reduce any debit balance or to reduce or satisfy any
      deficits in such other accounts except that no such transfer may be made
      from a segregated account subject to the Commodity Exchange Act to another
      account maintained by Customer unless either Customer has authorized such
      transfer in writing or DWR is effecting such transfer to enforce DWR's
      security interest pursuant to Section 13. DWR promptly shall confirm all
      transfers of funds made pursuant hereto to Customer in writing.

15.   DWR'S RIGHT TO LIQUIDATE CUSTOMER POSITIONS - In addition to all other
      rights of DWR set forth in this Agreement:

      (a)   when directed or required by a regulatory or self-regulatory
            organization or exchange having jurisdiction over DWR or the
            Account;

      (b)   whenever, in its discretion, DWR considers it necessary for its
            protection because of margin requirements or otherwise;

      (c)   if Customer or any affiliate of Customer repudiates, violates,
            breaches or fails to perform on a timely basis any term, covenant or
            condition on its part to be performed under this Agreement or
            another agreement with DWR;

      (d)   if a case in bankruptcy is commenced or if a proceeding under any
            insolvency or other law for the protection of creditors or for the
            appointment of a receiver, liquidator, trustee, conservator,
            custodian or similar officer is filed by or against Customer or any
            affiliate of Customer, or if Customer or any affiliate of Customer
            makes or proposes to make any arrangement or composition for the
            benefit of its creditors, or if Customer (or any such affiliate) or
            any or all of its property is subject to any agreement, order,
            judgment or decree providing for Customer's dissolution, winding-up,
            liquidation, merger, consolidation, reorganization or for the
            appointment of a receiver, liquidator, trustee, conservator,
            custodian or similar officer of Customer, such affiliate or such
            property;

      (e)   DWR is informed of Customer's death or mental incapacity; or

      (f)   if an attachment or similar order is levied against the Account or
            any other account maintained by Customer or any affiliate of
            Customer with DWR;

      DWR shall have the right to (i) satisfy any obligations due DWR out of any
      Customer's property in DWR's custody or control, (ii) liquidate any or all
      of Customer's commodity interest positions, (iii) cancel any or all of
      Customer's outstanding orders, (iv) treat any or all of Customer's
      obligations due DWR as immediately due and payable, (v) sell any or all of
      Customer's property in DWR's custody or control in such manner as DWR
      determines to be commercially reasonable, and/or (vi) terminate any or all
      of DWR's obligations for future performance to Customer, all without any
      notice to or demand on Customer. Any sale hereunder may be made in any
      commercially reasonable manner. Customer agrees that a prior demand, call
      or notice shall not be considered a waiver of DWR's right to act without
      demand or notice as herein provided, that Customer shall at all times be
      liable for the payment of any debit balance owing in each account upon
      demand whether occurring upon a liquidation as provided under this Section
      15 or otherwise under this Agreement, and that in all cases Customer shall
      be liable for any deficiency remaining in each Account in the event of
      liquidation thereof in whole or in part together with interest thereon and
      all costs relating to liquidation and collection (including reasonable
      attorneys' fees).

16.   CUSTOMER REPRESENTATIONS, WARRANTIES AND AGREEMENTS - Customer represents
      and warrants to and agrees with DWR that:

      (a)   Customer has full power and authority to enter into this Agreement
            and to engage in the transactions and perform its obligations
            hereunder and contemplated hereby and (i) if a corporation or a

            agreement;

      (b)   Neither Customer nor any partner, director, officer, member, manager
            or employee of Customer nor any affiliate of Customer is a partner,
            director, officer, member, manager or employee of a futures
            commission merchant introducing broker, exchange or self-regulatory
            organization or an employee or commissioner of the Commodity Futures

            or otherwise provided in writing, (i) Customer is not a commodity
            pool or is exempt from registration under the rules of the

            verification of the information contained herein.

      (d)   Customer has determined that trading in commodity interests is
            appropriate for Customer, is prudent in all respects and does not
            and will not violate Customer's charter or by-laws (or other
            comparable governing document) or any law, rule, regulation,
            judgment, decree, order or agreement to which Customer or its
            property is subject or bound;

      (e)   As required by CFTC regulations, Customer shall create, retain and
            produce upon request of the applicable contract market, the CFTC or
            the United States Department of Justice documents (such as
            contracts, confirmations, telex printouts, invoices and documents of

            in the Account;

      (h)   DWR, for and on behalf of Customer, is authorized and empowered to
            place orders for commodity interest transactions through one or more

            obligated to Customer for any loss, damage, liability, cost or
            expense (including but not limited to loss of profits, loss of use,
            incidental or consequential damages) incurred or sustained by
            Customer and arising in whole or in part, directly or indirectly,
            from any fault, delay, omission, inaccuracy or termination of a
            system or DWR's inability to enter, cancel or modify an order on
            behalf of Customer on or through a system. The provisions of this
            Section 16(h) shall apply regardless of whether any customer claim
            arises in contract, negligence, tort, strict liability, breach of
            fiduciary obligations or otherwise; and

      (i)   If Customer is subject to the Financial Institution Reform, Recovery
            and Enforcement Act of 1989, the certified resolutions set forth
            following this Agreement have been caused to be reflected in the
            minutes of Customer's Board of Directors (or other comparable
            governing body) and this Agreement is and shall be, continuously
            from the date hereof, an official record of Customer.

      Customer agrees to promptly notify DWR in writing if any of the warranties
      and representations contained in this Section 16 becomes inaccurate or in
      any way ceases to be true, complete and correct.

17.   SUCCESSORS AND ASSIGNS - This Agreement shall inure to the benefit of DWR,
      its successors and assigns, and shall be binding upon Customer and
      Customer's executors, trustees, administrators, successors and assigns,
      provided, however, that this Agreement is not assignable by Customer
      without the prior written consent of DWR.

18.   MODIFICATION OF AGREEMENT BY DWR; NON-WAIVER PROVISION - This Agreement
      may only be altered, modified or amended by mutual written consent of the
      parties, except that if DWR notifies Customer of a change in this
      Agreement and Customer thereafter effects a commodity interest transaction
      in an account, Customer agrees that such action by Customer will
      constitute consent by Customer to such change. No employee of DWR other
      than DWR's General Counsel or his or her designee, has any authority to
      alter, modify, amend or waive in any respect any of the terms of this
      Agreement. The rights and remedies conferred upon DWR shall be cumulative,
      and its forbearance to take any remedial action available to it under this
      Agreement shall not waive its right at any time or from time to time
      thereafter to take such action.

19.   SEVERABILITY - If any term or provision hereof or the application thereof
      to any persons or circumstances shall to any extent be contrary to any
      exchange, government or self-regulatory regulation or contrary to any
      federal, state or local law or otherwise be invalid or unenforceable, the
      remainder of this Agreement or the application of such term or provision
      to persons or circumstances other than those as to which it is contrary,
      invalid or unenforceable, shall not be affected thereby.

20.   CAPTIONS - All captions used herein are for convenience only, are not a
      part of this Agreement, and are not to be used in construing or
      interpreting any aspect of this Agreement.

21.   TERMINATION - This Agreement shall continue in force until written notice
      of termination is given by Customer or DWR. Termination shall not relieve
      either party of any liability or obligation incurred prior to such notice.
      Upon giving or receiving notice of termination, Customer will promptly
      take all action necessary to transfer all open positions in each account
      to another futures commission merchant.

22.   ENTIRE AGREEMENT - This Agreement constitutes the entire agreement between
      Customer and DWR with respect to the subject matter hereof and supersedes
      any prior agreements between the parties with respect to such subject
      matter.

23.   GOVERNING LAW; CONSENT TO JURISDICTION -

      (a)   In case of a dispute between Customer and DWR arising out of or
            relating to the making or performance of this Agreement or any
            transaction pursuant to this Agreement (i) this Agreement and its
            enforcement shall be governed by the laws of the State of New York
            without regard to principles of conflicts of laws, and (ii) Customer
            will bring any legal proceeding against DWR in, and Customer hereby
            consents in any legal proceeding by DWR to the jurisdiction of, any
            state or federal court located within the State and City of New York
            in connection with all legal proceedings arising directly,
            indirectly or otherwise in connection with, out of, related to or
            from Customer's Account, transactions contemplated by this Agreement
            or the breach thereof. Customer hereby waives all objections
            Customer, at any time, may have as to the propriety of the court in
            which any such legal proceedings may be commenced. Customer also
            agrees that any service of process mailed to Customer at any address
            specified to DWR shall be deemed a proper service of process on the
            undersigned.

      (b)   Notwithstanding the provisions of Section 23 (a)(ii), Customer may
            elect at this time to have all disputes described in this Section
            resolved by arbitration. To make such election, Customer must sign
            the Arbitration Agreement set forth in Section 24. Notwithstanding
            such election, any question relating to whether Customer or DWR has
            commenced an arbitration proceeding in a timely manner, whether a
            dispute is within the scope of the Arbitration Agreement or whether
            a party (other than Customer or DWR) has consented to arbitration
            and all proceedings to compel arbitration shall be determined by a
            court as specified in Section 23 (a)(ii).

24.   ARBITRATION AGREEMENT (OPTIONAL) - Every dispute between Customer and DWR
      arising out of or relating to the making or performance of this Agreement
      or any transaction pursuant to this Agreement, shall be settled by
      arbitration in accordance with the rules, then in effect, of the National
      Futures Association, the contract market upon which the transaction giving
      rise to the claim was executed, or the National Association of Securities
      Dealers as Customer may elect. If Customer does not make such election by
      registered mail addressed to DWR at 130 Liberty Street, 29th Floor, New
      York, NY 10006; Attention: Deputy General Counsel, within 45 days after
      demand by DWR that the Customer make such election, then DWR may make such
      election. DWR agrees to pay any incremental fees which may be assessed by
      a qualified forum for making available a "mixed panel" of arbitrators,
      unless the arbitrators determine that Customer has acted in bad faith in
      initiating or conducting the proceedings. Judgment upon any award rendered
      by the arbitrators may be entered in any court having jurisdiction
      thereof.

      IN ADDITION TO FOREIGN FORUMS, THREE FORUMS EXIST FOR THE RESOLUTION OF
      COMMODITY DISPUTES: CIVIL COURT LITIGATION, REPARATIONS AT THE COMMODITY
      FUTURES TRADING COMMISSION ("CFTC") AND ARBITRATION CONDUCTED BY A
      SELF-REGULATORY OR OTHER PRIVATE ORGANIZATION.

      THE CFTC RECOGNIZES THAT THE OPPORTUNITY TO SETTLE DISPUTES BY ARBITRATION
      MAY IN SOME CASES PROVIDE MANY BENEFITS TO CUSTOMERS, INCLUDING THE
      ABILITY TO OBTAIN AN EXPEDITIOUS AND FINAL RESOLUTION OF DISPUTES WITHOUT
      INCURRING SUBSTANTIAL COSTS. THE CFTC REQUIRES, HOWEVER, THAT EACH
      CUSTOMER INDIVIDUALLY EXAMINE THE RELATIVE MERITS OF ARBITRATION AND THAT
      YOUR CONSENT TO THIS ARBITRATION AGREEMENT BE VOLUNTARY.

      BY SIGNING THIS AGREEMENT, YOU (1) MAY BE WAIVING YOUR RIGHT TO SUE IN A
      COURT OF LAW AND (2) ARE AGREEING TO BE BOUND BY ARBITRATION OF ANY CLAIMS
      OR COUNTERCLAIMS WHICH YOU OR DWR MAY SUBMIT TO ARBITRATION UNDER THIS
      AGREEMENT. YOU ARE NOT, HOWEVER, WAIVING YOUR RIGHT TO ELECT INSTEAD TO
      PETITION THE CFTC TO INSTITUTE REPARATIONS PROCEEDINGS UNDER SECTION 14 OF
      THE COMMODITY EXCHANGE ACT WITH RESPECT TO ANY DISPUTE WHICH MAY BE
      ARBITRATED PURSUANT TO THIS AGREEMENT. IN THE EVENT A DISPUTE ARISES, YOU
      WILL BE NOTIFIED IF DWR INTENDS TO SUBMIT THE DISPUTE TO ARBITRATION. IF
      YOU BELIEVE A VIOLATION OF THE COMMODITY EXCHANGE ACT IS INVOLVED AND IF
      YOU PREFER TO REQUEST A SECTION 14 "REPARATIONS" PROCEEDINGS BEFORE THE
      CFTC, YOU WILL HAVE 45 DAYS FROM THE DATE OF SUCH NOTICE IN WHICH TO MAKE
      THAT ELECTION.

      YOU NEED NOT AGREE TO THIS ARBITRATION AGREEMENT TO OPEN AN ACCOUNT WITH
      DWR. See 17 CFR 180.1-180.5. ACCEPTANCE OF THIS ARBITRATION AGREEMENT
      REQUIRES A SEPARATE SIGNATURE ON PAGE 8.

25.   CONSENT TO TAKE THE OTHER SIDE OF ORDERS (OPTIONAL) - Without its prior
      notice, Customer agrees that when DWR executes sell or buy orders on
      Customer's behalf, DWR, its directors, officers, employees, agents,
      affiliates, and any floor broker may take the other side of Customer's
      transaction through any account of such person subject to its being
      executed at prevailing prices in accordance with and subject to the
      limitations and conditions, if any, contained in applicable rules and
      regulations.

26.   AUTHORIZATION TO TRANSFER FUNDS (OPTIONAL) - Without limiting other
      provisions herein, DWR is authorized to transfer from any segregated
      account subject to the Commodity Exchange Act carried by DWR for the
      Customer to any other account carried by DWR for the Customer such amount
      of excess funds as in DWR's judgment may be necessary at any time to avoid
      a margin call or to reduce a debit balance in said account. It is
      understood that DWR will confirm in writing each such transfer of funds
      made pursuant to this authorization within a reasonable time after such
      transfer.

27.   SUBORDINATION AGREEMENT (APPLIES ONLY TO ACCOUNTS WITH FUNDS HELD IN
      FOREIGN COUNTRIES) - Funds of customers trading on United States contract
      markets may be held in accounts denominated in a foreign currency with
      depositories located outside the United States or its territories if the
      customer is domiciled in a foreign country or if the funds are held in
      connection with contracts priced and settled in a foreign currency. Such
      accounts are subject to the risk that events could occur which hinder or
      prevent the availability of these funds for distribution to customers.
      Such accounts also may be subject to foreign currency exchange rate risks.

      If authorized below, Customer authorizes the deposit of funds into such
      foreign depositories. For customers domiciled in the United States, this
      authorization permits the holding of funds in regulated accounts offshore
      only if such funds are used to margin, guarantee, or secure positions in
      such contracts or accrue as a result of such positions. In order to avoid
      the possible dilution of other customer funds, a customer who has funds
      held outside the United States agrees by accepting this subordination
      agreement that his claims based on such funds will be subordinated as
      described below in the unlikely event both of the following conditions are
      met: (1) DWR is placed in receivership or bankruptcy, and (2) there are
      insufficient funds available for distribution denominated in the foreign
      currency as to which the customer has a claim to satisfy all claims
      against those funds.

      By initialing the Subordination Agreement below, Customer agrees that if
      both of the conditions listed above occur, its claim against DWR's assets
      attributable to funds held overseas in a particular foreign currency may
      be satisfied out of segregated customer funds held in accounts denominated
      in dollars or other foreign currencies only after each customer whose
      funds are held in dollars or in such other foreign currencies receives its
      pro-rata portion of such funds. It is further agreed that in no event may
      a customer whose funds are held overseas receive more than its pro-rata
      share of the aggregate pool consisting of funds held in dollars, funds
      held in the particular foreign currency, and non-segregated assets of DWR.

      Account [check box if applicable]:

transactions in the Account, that in the unlikely event of DWR's bankruptcy, it prefers that
the bankruptcy trustee [check appropriate box]:

   A.   Liquidate all open contracts without first seeking instructions      [ ]
        either from or on behalf of Customer.

   B.   Attempt to obtain instructions with respect to the disposition of    [ ]
        all open contracts.
