                               Customer Agreement

In consideration of Banc of America Futures, Incorporated ("Broker") agreeing to
carry one or more electronic accounts ("Account(s)") for the undersigned
("Customer") and provide services to Customer in connection with the purchase
and sale of cash commodities, commodity futures contracts, options on cash
commodities, options on futures contracts, forward or leverage contracts and any
similar instruments ("Commodities") which may be purchased or sold by or through
Broker for Customer's Account(s), Customer agrees and represents that:

1. Broker authorization. Customer authorizes Broker to purchase and sell
Commodities, as either agent or principal, for Customer's Account(s) in
accordance with the oral or written instructions of Customer or persons
authorized in writing to act on Customer's behalf. All such instructions must
contain sufficient information to permit Broker to execute orders without the
exercise of discretion. Customer hereby waives any defense that any such
instruction was not in writing as may be required by the Statute of Frauds or
any other law, rule or regulation. Unless Customer specifies to the contrary,
Broker is authorized to execute all orders on any contract market, exchange,
board of trade or other market where such business is conducted which may be
deemed by Broker, in its sole and absolute discretion, to be appropriate.
Customer further authorizes Broker to employ clearing members (including,
without limitation, on exchanges where Broker is not a member), floor brokers
and other agents in connection with the execution, carrying, clearance, delivery
and settlement of any such purchases and sales of Commodities. Neither Broker
nor any managing director, officer, employee or affiliate of Broker will act as
a fiduciary, commodity pool operator, commodity trading advisor or investment
adviser in respect of Customer's Account(s) nor shall Broker have any
responsibility for compliance with any law or regulation governing the conduct
of fiduciaries, commodity pool operators, commodity trading advisors or
investment advisers.

2. Broker's responsibility. Broker will attempt to execute all orders which it
may, in its sole discretion, choose to accept for the purchase or sale of
Commodities in accordance with the oral or written instructions of the Customer.
Broker's purchase and sale of Commodities for Customer's Account(s) shall be
subject to the terms of this Agreement and to the constitution, bylaws, rules,
regulations, rulings of relevant exchanges or clearing houses, and to all
applicable governmental laws and regulations (collectively, "Rules of Law"),
including without limitation, any Rules of Law relating to the conduct of
Broker's futures trading business and Broker's status as a subsidiary of a
United States bank holding company; provided however, that Customer shall not be
relieved of any obligation hereunder by reason of Broker's failure to comply
with any of the foregoing; and provided further that Customer shall be granted
no rights under any Rules of Law solely as a consequence of having executed this
Agreement.

3. Margin. Customer, without notice or demand, shall deposit and continuously
maintain in Customer's Account(s) sufficient funds to comply with any and all
margin requirements established by Broker, in its sole and absolute discretion,
or if none has been established by Broker, to comply with all applicable
exchange or legally imposed margin requirements. Customer acknowledges and
agrees that margins required by Broker may exceed the minimum legally imposed or
exchange margin requirements and may be increased or decreased from time to time
at the sole discretion of Broker, without advance notice to Customer. No
previous margin requirement shall establish any precedent nor shall Broker be
bound by any such previous margin requirement. If requested by Broker, all
margin deposits shall be made immediately by bank wire transfer, and Customer
shall provide Broker with any information requested by Broker to confirm such
transfers. Broker shall not be liable to Customer for the loss of any margin
deposits which results, directly or indirectly, from the bankruptcy, insolvency,
liquidation, receivership, custodianship, or assignment for the benefit of
creditors of any bank, clearing broker, exchange, clearing organization or other
entity.

4. Position limits. Broker shall have the right to limit the size of any
positions (net or gross) of Customer with respect to Customer's Account(s) and
to refuse to accept orders to establish new positions. Customer shall not,
either acting alone or in combination with others, exceed any position limits
established under any Rules of Law unless Customer has obtained an exemption
from such limits and Broker has been provided with a copy thereof. Customer will
provide Broker with copies of any and all reports filed by Customer with any
regulatory or self-regulatory authorities regarding positions in Commodities
contracts held or controlled by Customer or held or controlled by any other
person on behalf of Customer.


5. Commissions and charges. Customer agrees to pay Broker on demand; (a)
brokerage and commission charges and initial service fees and on-going service
fees at Broker's rates as in effect from time to time ( whether or not other
customers of Broker pay different commissions or charges); (b) separate
commissions, at Broker's rates in effect from time to time upon the exercise or
offset of a Commodity option; (c) any fees, fines, penalties or other charges
imposed on any transaction undertaken for Customer by the exchange or clearing
organization through which it is executed and any fee or tax imposed on such
transactions by any competent authority or self-regulatory organization; (d) the
amount of any trading loss that may result from transactions in Customer's
Account(s); interest and service charges on any Customer deficit balances or on
any other amounts due from Customer at Bank of America N A's then prevailing
reference rate plus one percent together with Broker's costs and reasonable
attorney's fees incurred in collecting any such deficit.


6. Liquidation instructions/delivery. Customer shall provide Broker with
liquidating instructions on open futures positions in expiring contracts five
(5) business days prior to the last trading day or, alternatively, Customer
shall provide to Broker sufficient funds to take delivery or necessary delivery
documents by such deadline. If Customer fails to provide such instructions,
funds or documents by such deadline, Broker may, in its sole discretion, at any
time during the five-day period prior to the last trading day, without notice,
liquidate Customer's position or make or receive delivery on Customer's behalf
upon such terms and conditions as Broker deems advisable, and neither Broker's
exercise of such discretion or its timing shall impose any liability on Broker
or create a defense for Customer against any liability to Broker. If Broker
elects to make delivery on Customer's behalf, Customer authorizes Broker, in its
sole discretion, to borrow or purchase and deliver the necessary delivery
documents. Customer shall guarantee and hold Broker harmless against any costs,
losses, damages or premiums it may incur in making such delivery or may sustain
from its inability to borrow or purchase the necessary contracts and deliver the
necessary delivery documents. In the event Broker takes delivery of any property
for Customer's Account(s), Customer agrees to pay all delivery, storage,
insurance, interest and related charges, and to guarantee and hold Broker
harmless against any loss Broker may suffer directly or indirectly, from a
decline in the value of such property. Customer expressly acknowledges that,
particularly in volatile markets, the making or accepting of delivery may
involve a higher degree of risk than liquidating a position by offset.

7. Maintenance of offsetting positions. It is understood and agreed that Broker
shall liquidate any Commodities contracts for which an offsetting order is
entered by Customer, unless Customer instructs Broker not to liquidate such
Commodities contracts and to maintain the offsetting Commodities contracts as
open positions, provided, however, that Broker shall not be obligated to comply
with any such instructions given by Customer if Customer fails to provide Broker
with any representations, documentation or information reasonably requested by
Broker or if, in Broker's reasonable judgment, any failure to liquidate such
offsetting Commodities contracts against each other would result in a violation
of any Rules of Law.

8. Options and provisions

a.   Customer understands that

i.     all short options positions are subject to assignment at any time during
the life of the option, including positions established on the same day that
exercise notices are assigned;
ii.    exercise assignment notices shall be allocated randomly from among all
Customers' short options positions which are subject to exercise, and
iii.   such assignment will automatically result in a commodity futures contract
in Customer's Account(s). Any such future contract shall be subject to
additional margin as may be required with respect to such resulting futures
contract position.

b.   Customer understands that some exchanges and clearing houses have
     established cutoff times for the tender of exercise instructions and that
     an option will become worthless if instructions are not delivered before
     such expiration time. Customer also understands that certain exchanges and
     clearing houses automatically will exercise some "in-the-money" options
     unless instructed otherwise. Customer acknowledges full responsibility for
     taking action either to exercise or to prevent the exercise of an option
     contract. Broker is not required to take any action with respect to an
     option contract, including without limitation any action either to exercise
     a valuable option prior to its expiration date or to prevent the automatic
     exercise of an option, except upon Customer's express instructions. In the
     event that Customer's offset, exercise or closeout instructions cannot be
     executed under prevailing market conditions, Broker may, without notice or
     demand, offset, closeout, abandon or exercise the option and dispose of the
     commodity futures contract created by any such exercise upon any terms and
     by any method which it deems reasonable in its sole discretion.

9. Security interest

a.   All monies, securities, financial instruments, futures contracts, options,
     precious metals or other property (collectively, the "Collateral")
     maintained in the Customer's Account(s) or held for the benefit of the
     Customer by Broker or any of its affiliates, by any clearing house through
     which transactions are executed and/or positions are held by Broker or any
     of its affiliates, on behalf of Customer, now or at any future time, hereby
     are pledged to Broker and shall be subject to a general lien and security
     interest in Broker's favor to secure any and all indebtedness at any time
     owing from Customer to Broker. Customer agrees to take such actions and to
     execute and deliver such documents as Broker may reasonably require from
     time to time to perfect the lien and security interest granted hereunder.


b.   Customer authorizes Broker to borrow, pledge, repledge, hypothecate,
     rehypothecate, loan or invest any such Collateral without notice to
     Customer, whenever Broker deems it necessary or advisable for its
     protection. The rights of Broker set forth above shall be qualified by any
     applicable Rules of Law requiring the segregation of Customer's property.

10. Customer's events of default; Broker's remedies. In the event that:

a.   Customer commences a voluntary proceeding, or an involuntary proceeding is
     commenced against the Customer, under any applicable bankruptcy, insolvency
     or other similar law now or hereafter in effect, or a receiver, liquidator,
     trustee, custodian, sequestrator, or other similar official is appointed or
     takes possession (before or after the commencement of any such voluntary or
     involuntary case) of Customer or of any substantial part of the property of
     Customer, or Customer is insolvent, makes any general assignment for the
     benefit of creditors, or fails generally to pay debts as they become due,
     or any similar event shall occur;

b.   Customer shall take any corporate or other action to effect a dissolution,
     liquidation, reorganization, winding up of its affairs or similar event;

c.   Customer's Account(s) is being attached or garnished or Broker receives
     notice of such attachment or garnishment;

d.   Customer shall fail or refuse to pay margin or any other sum as and when
     pursuant to this Agreement or shall breach or default in the performance of
     any other obligation of Customer under this Agreement;

e.   Broker determines, acting in good faith that it is necessary or appropriate
     for any other reason, with or without regard to market quotations, that any
     Collateral or margins deposited with Broker to secure any Customer
     Account(s) is inadequate; then, and in any such event, Broker may at its
     election (in addition to any other rights or remedies it may have at law,
     in equity, under this Agreement or otherwise):

i.     sell, exercise, offset or otherwise liquidate any or all property long in
any Customer Account(s) with Broker or any affiliate of Broker; or clearinghouse
on which contracts are traded, and/or
ii.    buy in, offset or otherwise liquidate any or all property short in any
Customer Account(s) with Broker or any affiliate of Broker; or clearinghouse on
which contracts are traded, and/or
iii.   buy or sell property to enter into and liquidate straddle or spread
positions with respect to any property long or short in any Customer Account(s)
with Broker or any affiliate of Broker; or clearinghouse on which contracts are
traded, and/or
iv.    cancel any outstanding orders, close out any or all outstanding
contracts, close any Customer Account(s) with Broker or any affiliate, sell, set
off against or otherwise dispose of any property of Customer in the custody or
control of Broker or an affiliate of Broker (whether held as margin, or for
safekeeping or otherwise) and satisfy any obligation Customer may have to Broker
or an affiliate of Broker (either directly or by way of guarantee or suretyship)
out of any such property or the proceeds from the sale or other disposition
thereof; and/or
v.     exercise all rights and remedies of a secured party under the Uniform
Commercial Code and under other applicable law.
Any action referred to herein may be taken without notice to Customer. In all
cases, a prior demand, call or notice of the time or place of sale or purchase
shall not be considered a waiver of Broker's right to sell or to buy without
demand, call or notice as herein provided. Any purchase, sale, offset or
liquidation of property may be made according to Broker's judgment and in acting
in good faith in a commercially reasonable manner on any exchange, other
recognized electronic market, through a clearing house, at public auction, by
private transaction, or elsewhere as Broker deems appropriate. In the event that
the property held and applied by Broker pursuant to this Agreement is
insufficient for the payment in full of all liabilities of Customer due to
Broker and any affiliates of Broker, Customer shall remain liable for and shall
promptly pay the deficit upon demand, together with interest thereon and all
costs of collection incurred by Broker in collecting any sums owed hereunder and
any cost incurred in successfully defending against

                                       4

       not be responsible for the accuracy or completeness of, or Customer's

       process, and agrees that service of process upon Broker shall constitute
