      This  Commodity  Futures Customer Agreement  ("Agreement"),
dated as of May 1, 2000 between Morgan Stanley & Co. Incorporated
("Morgan   Stanley"),   Dean   Witter   Cornerstone   Fund    III
("Customer"), and acknowledged and agreed to Dean Witter Reynolds
Inc., the non-clearing commodity broker for the Customer ("DWR"),
shall govern the purchase and sale by Morgan Stanley of commodity
futures contracts and options thereon (collectively, "Contracts")
for the account and risk of Customer through one or more accounts
carried  by Morgan Stanley on behalf and in the name of  Customer
(collectively, the "Account").

    1.    Applicable Law.   The Account and all transactions  and
agreements  in  respect of the Account shall be  subject  to  all
applicable  Federal, state, exchange, clearing  house  and  self-
regulatory  agency  rules, regulations  and  interpretations  and
custom  and  usage  of  the trade.  All such rules,  regulations,
interpretations,  custom  and usage are hereinafter  collectively
referred to as "Applicable Law."

    2.    Customer's  Representations and Warranties.    Customer
represents  and warrants that (a) Customer has full right,  power
and  authority  to  enter  into this Agreement,  and  the  person
executing  this Agreement on behalf of Customer is authorized  to
do  so; (b) this Agreement is binding on Customer and enforceable
against  Customer in accordance with its terms; (c) Customer  may
lawfully  establish  and  open the Account  for  the  purpose  of
effecting  purchases  and  sales  of  Contracts  through   Morgan
Stanley; (d) transactions entered into pursuant to this Agreement
will  not  violate any applicable law (including  any  Applicable
Law)  to  which  Customer is subject or any  agreement  to  which
Customer  is subject or a party; and (e) all information provided
by  Customer in the Account Application preceding this  Agreement
(which  Application and the information contained therein  hereby
is  incorporated  into this Agreement) is true  and  correct  and
Customer shall immediately (and in no event later than within one
business  day)  notify  Morgan Stanley  of  any  change  in  such
information.

     3.   Payment and Interest Obligations.

           (a)    Compensation   Payments  to   Morgan   Stanley.
    Customer  shall pay Morgan Stanley upon demand (a) all  floor
brokerage charges, give-up fees, contract market, clearing house,
National Futures Association ("NFA") or clearing member  fees  or
charges;  (b)  any  tax  imposed  on  such  transactions  by  any
competent taxing authority; (c) the amount of any trading  losses
in  the  Account;  (d)  any debit balance or  deficiency  in  the
Account;  and  (e) any other amounts owed by Customer  to  Morgan
Stanley  with respect to the Account or any transactions therein.
DWR  shall  pay Morgan Stanley such charges with respect  to  the
execution  and clearing of trades for Customer as DWR and  Morgan
Stanley shall agree from time to time.

         (b)  Payment of Interest.   The Customer's assets deposited with
Morgan  Stanley will be segregated or secured in accordance  with
the  Commodity  Exchange  Act and regulations  of  the  Commodity
Futures  Trading  Commission ("CFTC") and  will  be  invested  in
accord with Morgan Stanley's customary practice for investment of
its  futures  customer funds.  All of Customer's  funds  will  be
available  for margin for the Customer's trading. Morgan  Stanley
shall  pay to DWR at each month-end interest on Customer's  funds
in  its possession as agreed between Morgan Stanley and DWR  from
time  to time.  The Customer understands that it will not receive
any  interest  income on its assets held by Morgan Stanley  other
than  that  paid by DWR pursuant to the Customer's  DWR  Customer
Agreement.   DWR shall pay Morgan Stanley interest on  any  debit
balances in the Account at such rates as Morgan Stanley  and  DWR
shall agree from time to time.


         <PAGE>
         (c)   Netting.      The parties agree that  all  payment
obligations  of  Customer to Morgan Stanley under this  Agreement
and  all payment obligations of Morgan Stanley to Customer  under
this Agreement will be netted against each other to result in one
net payment amount.

    4.  Customer's Events Of Default; Morgan Stanley's Remedies.

          (a)   Events of Default.   As used herein, each of  the
following  shall  be  deemed  an "Event  of  Default":   (i)  the
commencement  of  a  case under any Federal or state  bankruptcy,
insolvency or reorganization law, or the filing of a petition for
the  appointment  of  a  receiver  by  or  against  Customer,  an
assignment  made  by Customer for the benefit  of  creditors,  an
admission  in  writing by Customer that it  is  insolvent  or  is
unable  to  pay its debts when they mature, or the suspension  by
the  Customer  of  its  usual business or  any  material  portion
thereof;  (ii) the issuance of any warrant or order of attachment
against  the  Account  or  the levy of  a  judgment  against  the
Account;  (iii)  if  Customer is an employee  benefit  plan,  the
termination of Customer or the filing by Customer of a notice  of
intent  to terminate with a governmental agency or body,  or  the
receipt  of  a  notice  of intent to terminate  Customer  from  a
governmental agency or body, or the inability of Customer to  pay
benefits  under  the relevant employment benefit plan  when  due;
(iv)  the failure by Customer to deposit or maintain margins,  to
pay required premiums, or to make payments required by Section  3
hereof;  (v) the failure by Customer to perform, in any  material
respect, its obligations hereunder.

         (b)    Remedies.   Upon the occurrence of  an  Event  of
Default  or in the event Morgan Stanley, in its sole and absolute
discretion,  considers  it necessary for its  protection,  Morgan
Stanley  shall  have the right, in addition to any  other  remedy
available to Morgan Stanley at law or in equity, and in  addition
to any other action Morgan Stanley may deem appropriate under the
circumstances, to liquidate any or all open Contracts held in  or
for  the  Account,  sell any or all of the  securities  or  other
property  of  Customer held by Morgan Stanley and  to  apply  the
proceeds  thereof  to  any amounts owed  by  Customer  to  Morgan
Stanley,  borrow  or  buy any options, securities,  Contracts  or
other property for the Account and cancel any unfilled orders for
the  purchase or sale of Contracts for the Account, or take  such
other  or  further  actions  Morgan Stanley,  in  its  reasonable
discretion,  deems necessary or appropriate for  its  protection,
all   without   demand   for  margin  and   without   notice   or
advertisement.  Any such action may be made at the discretion  of
Morgan  Stanley  in any commercially reasonable manner.   In  the
event Morgan Stanley's position would not be jeopardized thereby,
Morgan   Stanley   will  make  reasonable   efforts   under   the
circumstances to notify Customer prior to taking any such action.
A  prior demand or margin call of any kind from Morgan Stanley or
prior notice from Morgan Stanley shall not be considered a waiver
of  Morgan  Stanley's right to take any action without notice  or
demand.   In  the  event  Morgan Stanley exercises  any  remedies
available  to it under this Agreement, Customer shall  reimburse,
compensate  and indemnify Morgan Stanley for any and  all  costs,
losses,  penalties, fines, taxes and damages that Morgan  Stanley
may  incur,  including  reasonable attorneys'  fees  incurred  in
connection with the exercise of its remedies and the recovery  of
any such costs, losses, penalties, fines, taxes and damages.

     5.   Standard of Liability and Indemnification.

           (a)   Standard of Liability.   Morgan Stanley and  its
stockholders, directors, officers, employees, and  its  or  their
respective  successors or assigns shall  not  be  liable  to  the
Customer,  its  partners,  or  any of  its  or  their  respective
successors or assigns, except by reason of acts, or omissions due
to, bad faith, misconduct, or negligence, or for not having acted
in  good  faith  in  the  reasonable belief  that  such  acts  or
omissions were in, or not opposed to, the best interests  of  the
Customer,  or by reason of any material breach of this  Agreement
by Morgan Stanley. Without limiting the foregoing, Morgan Stanley
shall  have no responsibility or liability to Customer  hereunder
(i)  in connection with the performance or non-performance by any
contract  market, clearing house, clearing firm  or  other  third
party (including floor brokers not selected by Morgan Stanley and
banks)  to  Morgan Stanley of its obligations in respect  of  any
Contract                        or                         <PAGE>
other  property of Customer; (ii) as a result of any  prediction,
recommendation  or  advice made or given by a  representative  of
Morgan  Stanley  whether or not made or given at the  request  of
Customer; (iii) as a result of Morgan Stanley's reliance  on  any
instructions, notices and communications that it believes  to  be
that  of  an individual authorized to act on behalf of  Customer;
(iv)  as  a  result  of  any  delay in the  performance  or  non-
performance  of  any  of  Morgan Stanley's obligations  hereunder
directly   or  indirectly  caused  by  the  occurrence   of   any
contingency  beyond the control of Morgan Stanley including,  but
not  limited  to,  the  unscheduled closure  of  an  exchange  or
contract  market or delays in the transmission of orders  due  to
breakdowns   or   failures  of  transmission   or   communication
facilities, execution, and/or trading facilities or other systems
(including,   without  limitation,  GLOBEX,  ACCESS,   or   other
electronic  trading  systems, facilities or services),  it  being
understood  that Morgan Stanley shall be excused from performance
of  its  obligations  hereunder for such period  of  time  as  is
reasonably necessary after such occurrence to remedy the  effects
therefrom; (v) as a result of any action taken by Morgan  Stanley
or  its floor brokers to comply with Applicable Law; or (vi)  for
any acts or omissions of those neither employed nor supervised by
Morgan  Stanley.  In no event will Morgan Stanley  be  liable  to
Customer   for  consequential,  incidental  or  special   damages
hereunder.

           (b)  Indemnification by Customer.   The Customer shall
indemnify  and hold harmless Morgan Stanley and its stockholders,
directors,  officers,  employees, and  its  or  their  respective
successors  or  assigns  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 or conduct undertaken by Morgan Stanley 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 a court  of
competent  jurisdiction upon entry of final judgment  shall  find
(or,  if no final judgment is entered, an opinion is rendered  to
the  Customer  by  independent counsel who shall  be  other  than
counsel to the Customer or Morgan Stanley) to the effect that the
conduct that was the basis for such liability was not the  result
of  bad  faith misconduct, or negligence, and was done in a  good
faith  belief  that  it  was  in, or not  opposed  to,  the  best
interests of the Customer.

            (c)   Indemnification  by  Morgan  Stanley.    Morgan
Stanley  shall  indemnify  and hold harmless  the  Customer,  its
partners, and its or their respective successors or assigns  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  or  conduct
undertaken  by Morgan Stanley on behalf of the Customer  pursuant
to   this   Agreement,  provided  that  a  court   of   competent
jurisdiction upon entry of final judgment shall find (or,  if  no
final judgment is entered, by an opinion rendered to the Customer
by  independent  counsel who shall be other than counsel  to  the
Customer  or Morgan Stanley) to the effect that the conduct  that
was  the  basis for such liability was the result of  bad  faith,
misconduct, or negligence, or was not done in a good faith belief
that  it  was  in, or not opposed to, the best interests  of  the
Customer,  or  was  by  reason of any  material  breach  of  this
Agreement by Morgan Stanley.

           (d)   Limitation  on  Indemnities.    The  indemnities
provided in this Section 5 by Customer to Morgan Stanley and  its
stockholders, directors, officers, employees, and  its  or  their
respective  successors and assigns shall be inapplicable  in  the
event  of  any  liability  arising out of,  or  based  upon,  any
material breach of any warranty, covenant, or agreement of Morgan
Stanley contained in this Agreement to the extent caused by  such
event.  Likewise, the indemnities provided in this Section  5  by
Morgan  Stanley to the Customer, its partners, and any of its  or
their respective successors and assigns shall be inapplicable  in
the  event  of any liability 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
event.

    <PAGE>
    6.   General Agreements.   The parties agree that:

         (a)    Morgan Stanley's Responsibility.   Morgan Stanley
is  not acting as a fiduciary, foundation manager, commodity pool
operator,  commodity  trading advisor or  investment  adviser  in
respect of any Account opened by Customer.  Morgan Stanley  shall
have  no responsibility hereunder for compliance with any law  or
regulation  governing  the  conduct  of  fiduciaries,  foundation
managers, commodity pool operators, commodity trading advisors or
investment advisers.

                Morgan  Stanley agrees to furnish to the Customer
as  soon as practicable all of the information from time to  time
in  its  possession which Customer may be required to furnish  to
its   limited   partners  pursuant  to  its  limited  partnership
agreement  and as otherwise required by Applicable  Law.   Morgan
Stanley shall disclose such information regarding itself and  its
affiliates  (including, without limitation, financial statements)
as  may be required by the Customer for SEC, CFTC and state  blue
sky  disclosure purposes.  Morgan Stanley agrees  to  notify  the
applicable  trading  advisor for the Customer  (each  a  "Trading
Advisor")  immediately upon discovery of any error  committed  by
Morgan  Stanley or any of its agents with respect to a trade  for
the  Customer's  account which Morgan Stanley  believes  was  not
executed or cleared in accordance with proper instructions  given
by  the  Customer,  its Trading Advisors or any other  authorized
agent  of  Customer.  Errors made by floor brokers  appointed  or
selected by Morgan Stanley shall constitute errors made by Morgan
Stanley.   However, Morgan Stanley shall not be  responsible  for
errors committed by the Trading Advisors.

                Morgan  Stanley agrees to report to DWR  its  own
errors  and  the  errors of any Trading Advisor for  the  Account
which  Morgan  Stanley  becomes  aware  of,  provided  that  such
reporting  may  be via telephone. Notwithstanding the  foregoing,
the  failure  to comply with such reporting obligation  does  not
increase  Morgan  Stanley's liability for its own  errors  beyond
that otherwise expressly set forth in this Agreement, nor does it
make  Morgan Stanley in any way responsible for errors  committed
by the Trading Advisors.

                Morgan   Stanley  acknowledges  that  the   other
partnerships of which Demeter Management Corporation (the general
partner  of  Customer) is the general partner, do not  constitute
affiliates of the Customer.

          (b)    Advice.    All  advice  communicated  by  Morgan
Stanley  with respect to any Account opened by Customer hereunder
is  incidental to the conduct of Morgan Stanley's business  as  a
futures commission merchant and such advice will not serve as the
primary  basis for any decision made by or on behalf of  Customer
in  respect of the Account, regardless of whether Customer relies
on  the  advice  of Morgan Stanley in making any  such  decision.
Customer  acknowledges  that  Morgan  Stanley  and  its  managing
directors,  officers, employees and affiliates may take  or  hold
positions  in,  or  advise other customers concerning,  Contracts
that  are  the subject of advice from Morgan Stanley to Customer.
The  positions  and  advice of Morgan Stanley  and  its  managing
directors, officers, employees and affiliates may be inconsistent
with or contrary to positions of, and the advice given by, Morgan
Stanley to Customer.

         (c)   Recording.   Each of Morgan Stanley, the Customer,
DWR and their respective officers, agents and employees, in their
sole  and  absolute discretion, may record, on tape or otherwise,
any  telephone conversation between or among Morgan Stanley,  the
Customer  or  DWR  with respect to the Account  and  transactions
therein  and each of Morgan Stanley, the Customer and DWR  hereby
agrees and consents thereto.

         <PAGE>
         (d)  Acceptance of Orders; Position Limits.

              (i)   Morgan Stanley shall have the right to  limit
    the  size  of open positions (net or gross) of Customer  with
    respect  to  the Account at any time and to refuse acceptance
    of  orders  to establish new positions, whether such  refusal
    or  limitation  is required by, or based on  position  limits
    imposed   under,  Applicable  Law.   Morgan   Stanley   shall
    immediately  notify Customer of its rejection of  any  order.
    Unless  specified by Customer, Morgan Stanley  may  designate
    the   exchange   or   other   markets   (including,   without
    limitation,  GLOBEX or ACCESS) on which it  will  attempt  to
    execute orders.

              (ii)  Customer shall file or cause to be filed  all
    applications  or reports required under Applicable  Law  with
    the  CFTC or the relevant contract market or clearing  house,
    and  shall  provide  Morgan  Stanley  with  a  copy  of  such
    applications or reports and such other information as  Morgan
    Stanley may reasonably request in connection therewith.

          (e)   Original  and Variation Margin;  Premiums;  Other
Contract Obligations.   Customer shall make, or cause to be made,
all  applicable  original margin, intra-day  margin  and  premium
payments,   and  perform  all  other  obligations  attendant   to
transactions or positions in such Contracts, as may  be  required
by  Applicable  Law  or by Morgan Stanley.  Requests  for  margin
deposits   and/or  premium  payments  may,  at  Morgan  Stanley's
election,  be communicated to Customer orally, telephonically  or
in  writing.   Customer margin deposits and/or  premium  payments
shall  be  made  by  wire transfer to Morgan  Stanley's  Customer
Segregated  Account  and shall be in U.S. dollars  unless  Morgan
Stanley  and  the  Customer specifically  agree  otherwise.   All
Contracts  for  the Account shall be margined at  the  applicable
exchange   or   clearing  house  minimum  rates  for  speculative
accounts.

          (f) Security Interest and Rights Respecting Collateral.
Except to the extent proscribed by Applicable Law not subject  to
waiver,  all  Contracts,  cash,  securities,  and/or  any   other
property  of Customer whatsoever (collectively, the "Collateral")
at  any time held by Morgan Stanley or its affiliates, or carried
by  others for the Account, hereby are pledged to Morgan  Stanley
and  shall be subject to a general lien and security interest  in
Morgan  Stanley's  favor  to  secure any  indebtedness  or  other
amounts,  obligations and/or liabilities at any time  owing  from
Customer   to   Morgan  Stanley  (collectively,  the  "Customer's
Liabilities").  Customer hereby grants Morgan Stanley  the  right
to  borrow, pledge, repledge, hypothecate, rehypothecate, loan or
invest  any  of the Collateral held by Morgan Stanley,  including
utilizing  the  Collateral to purchase United  States  Government
Treasury obligations pursuant to repurchase agreements or reverse
repurchase agreements with any party, in each case without notice
to  Customer and without any obligation to pay or to  account  to
Customer for any interest, income or benefit that may be  derived
therefrom.  The rights of Morgan Stanley set forth above shall be
qualified  by  any  applicable requirements  for  segregation  of
customers' property under Applicable Law.  Morgan Stanley commits
to  Customer  that  Morgan Stanley will not  issue  a  Notice  of
Exclusive  Control  under  the Control Agreement  between  Morgan
Stanley  and  DWR  unless Morgan Stanley determines  there  is  a
default under this Agreement.

          (g)    Reports  and  Objections.    All  confirmations,
purchase  and  sale  notices,  correction  notices  and   account
statements  (collectively, "Statements") shall  be  submitted  to
Customer  and shall be conclusive and binding on Customer  unless
Customer  notifies Morgan Stanley of any objection thereto  prior
to  the  opening of trading on the contract market on which  such
transaction  occurred on the business day following  the  day  on
which  Customer  receives  such Statement;  provided  that,  with
respect to monthly Statements, Customer may notify Morgan Stanley
of  any objection thereto within five business days after receipt
of  such monthly Statement, provided the objection could not have
been  raised  at  the time any prior Statement  was  received  by
Customer as provided for above.  Any such notice of objection, if
given orally to
          <PAGE>
Morgan  Stanley, shall immediately (and no later than within  one
business day) be confirmed in writing by Customer.

          (h) Delivery Procedures; Options Allocation Procedure.

               (i)  Customer  will  provide Morgan  Stanley  with
    instructions   either   to  liquidate  Contracts   previously
    established  by  Customer, make or take  delivery  under  any
    such   Contracts,  or  exercise  options  entered   into   by
    Customer,  within  such time limits as may  be  specified  by
    Morgan  Stanley.  Morgan Stanley shall have no responsibility
    to  take any action on behalf of Customer or positions in the
    Account  unless  and until Morgan Stanley  receives  oral  or
    written  instructions reasonably acceptable to Morgan Stanley
    indicating  the  action Morgan Stanley  is  to  take.   Funds
    sufficient  to  take delivery pursuant to  such  Contract  or
    deliverable  grade commodities to make delivery  pursuant  to
    such  Contract  must be delivered to Morgan Stanley  at  such
    time  as  Morgan Stanley may require in connection  with  any
    delivery.

               (ii)  Short  option Contracts may  be  subject  to
    exercise  at any time.  Exercise notices received  by  Morgan
    Stanley  from the applicable contract market with respect  to
    option  Contracts  sold  by  Customer  may  be  allocated  to
    Customer  pursuant  to  a  random allocation  procedure,  and
    Customer  shall be bound by any such allocation  of  exercise
    notices.  In the event of any allocation to Customer,  unless
    Morgan  Stanley  has  previously received  instructions  from
    Customer,  Morgan Stanley's sole responsibility shall  be  to
    use its best efforts to notify Customer of such allocation.

               (iii)                If  Customer fails to  comply
    with  any  of the foregoing obligations, Morgan Stanley  may,
    in  its  sole  and  absolute discretion, liquidate  any  open
    positions,  make  or receive delivery of any  commodities  or
    instruments,  or  exercise or allow  the  expiration  of  any
    options,  in such manner and on such terms as Morgan Stanley,
    in  its  sole  and  absolute discretion, deems  necessary  or
    appropriate,  and Customer shall indemnify  and  hold  Morgan
    Stanley  harmless  as  a result of any action  taken  or  not
    taken  by  Morgan Stanley in connection therewith or pursuant
    to Customer's instructions.

         (i)   Financial and Other Information.   Customer  shall
provide  to  Morgan Stanley such financial information  regarding
Customer  as  Morgan  Stanley may from time  to  time  reasonably
request.   Customer shall notify Morgan Stanley immediately  (and
no later than within one business day) if the financial condition
of  Customer changes materially and adversely from that shown  in
the  most  recent financial information theretofore  provided  to
Morgan Stanley.  An investigation may be conducted pertaining  to
Customer's credit standing and business.

         (j)   Currency Exchange Risk.   Customer shall bear  all
risk and cost in respect of the conversion of currencies incident
to transactions effected on behalf of Customer pursuant hereto.

    7.   Termination.   This Agreement may be terminated  at  any
time  by  Customer  or Morgan Stanley upon thirty  (30)  days  by
written  notice  to  the  other.  In the event  of  such  notice,
Customer shall either close out open positions in the Account  or
arrange  for  such  open positions to be transferred  to  another
futures  commission merchant.  Upon satisfaction by  Customer  of
all  of Customer's Liabilities, Morgan Stanley shall transfer  to
another  futures commission merchant all Contracts, if any,  then
held  for  the  Account, and shall transfer  to  Customer  or  to
another  futures commission merchant, as Customer  may  instruct,
all  cash,  securities and other property held  in  the  Account,
whereupon  this  Agreement shall terminate.  Notwithstanding  the
foregoing,  in  the  event  Morgan  Stanley  is  required  by   a
regulatory  authority to transfer the account to another  futures
commission merchant or in the event that Morgan Stanley  abandons
the  Futures  Commission Merchant ("FCM") business,  then  Morgan
Stanley              shall              have               <PAGE>
the right to terminate this Agreement by written notice effective
the   date  contained  therein,  provided  that  Morgan   Stanley
cooperates in the transfer of open positions to another  FCM  and
that  the  termination  of the Agreement is  not  made  effective
earlier than the completion of the transfer.

    8.   Miscellaneous.

          (a)  Severability.   If any provision of this Agreement
is,  or  at  any time becomes, inconsistent with any  present  or
future  law, rule or regulation of any exchange or other  market,
sovereign  government or regulatory body thereof, and if  any  of
these  authorities have jurisdiction over the subject  matter  of
this  Agreement,  the  inconsistent  provision  shall  be  deemed
superseded  or  modified  to  conform  with  such  law,  rule  or
regulation  but  in  all  other respects,  this  Agreement  shall
continue and remain in full force and effect.

          (b)   Binding Effect.   This Agreement shall be binding
on  and inure to the benefit of the parties and their successors.
Morgan  Stanley shall have the right to transfer or  assign  this
Agreement  (and thereby the Account) to any successor  entity  in
its  sole  and  absolute  discretion and  without  obtaining  the
consent of Customer.

          (c)   Entire  Agreement.   This Agreement contains  the
entire  agreement  between the parties and supersedes  any  prior
agreements  between the parties as to the subject matter  hereof.
No  provision of this Agreement shall in any respect  be  waived,
altered,  modified,  or amended unless such  waiver,  alteration,
modification  or  amendment is signed by the party  against  whom
such  waiver,  alteration, modification or  amendment  is  to  be
enforced.

          (d)   Currency Denomination.   Unless another  currency
is designated in the confirmations reporting transactions entered
into  by  Customer, all margin deposits in connection  with  such
transactions,  and  a debit or credit in the  Account,  shall  be
stated  in United States dollars, and margin requirements, debits
or  credits expressed in another currency shall be converted into
United  States dollars at a rate of exchange determined by Morgan
Stanley, in its sole and absolute discretion, on the basis of the
then  prevailing money market rates of exchange for such  foreign
currency.
