RIO VISTA ENERGY PARTNERS L.P.

COMMON UNIT PURCHASE WARRANT

This Warrant certifies that, for value received, TCW Energy Funds X Holdings, L.P., a
California limited partnership, or its registered assigns (“Holder”), is entitled to purchase from
Rio Vista Energy Partners L.P., a Delaware limited partnership (the “Partnership”):

(a) at any time or from time to time after May 19, 2008 until such time as the Demand Loan
(the “Demand Loan”) under the Note Purchase Agreement dated as of November 19, 2007 (the “Note
Purchase Agreement”) by and among Rio Vista Penny LLC (“Rio Vista Penny”), TCW Asset Management
Company, a California corporation (“TAMCO”), TCW Energy Fund X-NL, L.P., a California limited
partnership, TCW Energy Fund XB-NL, L.P., a California limited partnership, TCW Energy Fund XC-NL,
L.P., a California limited partnership, TCW Energy Fund XD-NL, L.P., a California limited
partnership, TAMCO, as Investment Manager under the Amended and Restated Investment Management and
Custody Agreement dated as of December 3, 2003 among Ensign Peak Advisors, Inc., TAMCO, and Trust
Company of the West (“TCW”), a California trust company, as Sub-Custodian; TAMCO as Investment
Manager under the Amended and Restated Investment Management and Custody Agreement dated as of
March 18, 2004 among ING Life Insurance and Annuity Company, TAMCO, and TCW as Sub Custodian; and
TAMCO as Investment Manager under the Amended and Restated Investment Management and Custody
Agreement dated as of December 11, 2003 among Harry L. Bradley, Jr. Partition Trust, Harry L.
Bradley, Jr. Trust, Jane Bradley Uihlien Pettit Partition Trust, Jane Bradley Uihlien Trust, TAMCO,
and TCW as Sub-Custodian, (such entities, the “Note Holders”) is paid in full (the “Tranche 1
Exercise Period”), that number of fully paid and non-assessable common units of the Partnership
derived by dividing (i) the amount of outstanding principal owed by Rio Vista Penny to the Note
Holders pursuant to the Demand Loan, by (ii) the Tranche 1 Exercise Price (defined below), at an
exercise price equal to the lower of (A) $13.33 per common unit (the “Fixed Tranche 1 Price”) and
(B) (x) 90% multiplied by (y) the average Market Price for the 20 trading days preceding the date
of Holder’s election to exercise this Warrant for such Tranche 1 Warrant Units pursuant to
Section 1 (such lower price, the “Tranche 1 Exercise Price”), and

 

 

 

(b) at any time or from time to time after November 19, 2008 until such time as the outstanding
amounts under the Note Purchase Agreement (other than the Demand Loan) are paid
in full (the “Tranche 2 Exercise Period”), that number of fully paid and non-assessable common
units of the Partnership derived by dividing (i) the amount of outstanding principal, accrued
interest, and expenses owed by Rio Vista Penny to Holder pursuant to the Note Purchase Agreement,
less the amount of outstanding principal under the Demand Loan, on the date of Holder’s election to
exercise this Warrant for such Tranche 2 Warrant Units pursuant to Section 1, by (ii) the
Tranche 2 Exercise Price (defined below) for an exercise price (the “Tranche 2 Exercise Price”)
equal to (x) 90% multiplied by (y) the average Market Price for the 20 trading days preceding the
date of Holder’s election to exercise this Warrant for such Tranche 2 Warrant Units pursuant to
Section 1. As used herein, the term “Warrant Units” refers to the common units of the
Partnership issuable upon exercise of this Warrant, the term “Tranche 1 Warrant Units” refers to
the common units of the Partnership issuable upon the exercise of this Warrant during the Tranche 1
Exercise Period, and the term “Tranche 2 Warrant Units” refers to the common units of the
Partnership issuable upon the exercise of this Warrant during the Tranche 2 Exercise Period. The
Fixed Tranche 1 Price and number of Tranche 1 Warrant Units is subject to adjustment as provided in
Section 3 hereof.

For the purposes of this Warrant, the “Market Price” on any day shall be the last sale price
on such day on the NASDAQ Stock Market, or, if the common units are not then listed or admitted to
trading on the NASDAQ Stock Market, on such other principal stock exchange on which such units are
then listed or admitted to trading, or, if no sale takes place on such day on any such exchange,
the average of the closing bid or asked prices on such day as officially quoted on any such
exchange, or, if the common units are not then listed or admitted to trading on any stock
exchange, the average of the reported closing bid and asked prices on such day in the
over-the-counter market as quoted on the National Association of Securities Dealers Automated
Quotation System or, if not so quoted, then as furnished by any member of the National Association
of Securities Dealers, Inc. selected by the Partnership. If there shall be no meaningful
over-the-counter market, the Market Price shall be the fair market value as determined solely by
the general partner of the Partnership (with such fair market value being equal to or in excess of
the book value).

This Warrant, together with all warrants issued upon transfer, exchange or in replacement
hereof pursuant to Section 7 hereof (collectively, the “Warrants”), is subject to the
following additional terms, provisions, and conditions:

Section 1.
Manner of Exercise; Issuance of Certificates; Payment for Warrant Units.
Subject to the provisions hereof, this Warrant may be exercised by Holder, in whole or in
part, by the surrender of this Warrant, together with a completed Exercise Agreement in the form
attached hereto, to the Partnership during normal business hours on any business day at the
Partnership’s office in El Segundo, California (or such other office or agency of the Partnership
as it may designate by notice to Holder), during, with respect to the Tranche 1 Warrant Units, the
Tranche 1 Exercise Period, and with respect to the Tranche 2 Warrant Units, the Tranche 2 Exercise
Period, and upon payment to the Partnership of the Tranche 1 Exercise Price for the Tranche 1
Warrant Units or the Tranche 2 Exercise Price for the Tranche 2 Warrant Units specified in said
Exercise Agreement. Payment of the Tranche 1 Exercise Price shall be made by Holder by reducing
the outstanding principal owed by Rio Vista Penny to the Note Holders under the Demand Loan by the
amount of such payment. Payment of the Tranche 2 Exercise Price shall be made by Holder by
reducing the outstanding principal (other than pursuant to the
Demand Loan), accrued interest, and expenses owed by Rio Vista Penny to the Note Holders pursuant
to the Note Purchase Agreement by the amount of such payment.

The Partnership shall not be required to issue fractional Warrant Units upon any exercise of
this Warrant, but instead the value of any such fractional Warrant Units shall remain outstanding
under the Note Purchase Agreement. The Warrant Units so purchased shall be deemed to be issued to
Holder or its designees as the record owner of such shares as of the close of business on the date
or dates on which this Warrant shall have been surrendered, the completed Exercise Agreement
delivered, and payment made for such Warrant Units as aforesaid. Certificates for the Warrant Units
so purchased, representing the aggregate number of common units specified in said Exercise
Agreement, shall be delivered to Holder within a reasonable time, not exceeding ten business days,
after this Warrant shall have been so exercised.

The Warrant Units so delivered shall be in such denominations as may be reasonably requested
by Holder, shall be listed for trading on any NASDAQ Stock Market (or such other exchange as the
common units are then listed or traded), and shall be registered in the name of Holder or such
other name as shall be designated by Holder. The Partnership will file a registration statement on
Form S-3 (the “Registration Statement”) under the Securities Act of 1933, as amended (the
“Securities Act”) covering the Warrant Units within 90 days following the first exercise of this
Warrant and will use commercially reasonable efforts to cause the Registration Statement to be
declared effective as soon as practicable thereafter. The Partnership will maintain the
effectiveness of the Registration Statement until the Warrant Units have been resold pursuant to
the Registration Statement or are eligible for resale, without restriction, pursuant to Rule 144
of the Securities Act.

Holder will cooperate with the Partnership as reasonably requested by the Partnership in
connection with the preparation and filing of the Registration Statement. Holder will furnish to
the Partnership such information regarding itself, the common units held by it, and the intended
method of disposition of such common units as shall be reasonably required to cause the
effectiveness of the Registration Statement and will execute and deliver such documents in
connection with the Registration Statement as the Partnership may reasonably request. Holder will,
upon receipt of notice from the Partnership of any event requiring suspension of the use of the
prospectus included as part of the Registration Statement, immediately discontinue disposition of
common units pursuant to the Registration Statement until Holder’s receipt of the copies of the
supplemented or amended prospectus or receipt of notice that no supplement or amendment is
required. Holder covenants and agrees that it will comply with the prospectus delivery
requirements of the Securities Act as applicable to it or comply with the provisions of an
exemption from such prospectus delivery requirements in connection with sales of common units
pursuant to the Registration Statement.

With respect to the Tranche 1 Warrant Units, if, on the date the Registration Statement is
declared effective by the Securities and Exchange Commission and the Warrant Units are not subject
to contractual restriction on resale (the “Registration
Date”), the Market Price (the
“Registration Date Price”) is less than the Market Price on the date of such exercise of this
Warrant for such Warrant Units (the “Exercise Date Price”), the Partnership and Rio Vista Penny
jointly agree to deliver to Holder either (i) additional common units of the Partnership (the
“Additional Units”) in such number as necessary so
that the aggregate value (based on the Registration Date Price) of (A) the Tranche 1 Warrant Units issued to Holder in connection with
such exercise plus (B) the Additional Units, equals the value (based on the Exercise Date Price) of
the Tranche 1 Warrant Units issued to Holder in connection with such exercise, or (ii) cash (the
“Additional Cash”) in such amount as necessary so that the aggregate value of (A) the Tranche 1
Warrant Units (based on the Registration Date Price) issued to Holder in connection with such
exercise plus (B) the Additional Cash, equals at least the value (based on the Exercise Date Price)
of the Tranche 1 Warrant Units issued to Holder in connection with such exercise. In lieu of
delivery of Additional Units or Additional Cash as provided above, the Partnership and Rio Vista
Penny may elect to pay cash to Holder equal to the aggregate value (based on the Exercise Date
Price) of the Tranche 1 Warrant Units issued to Holder in connection with such exercise (the “All
Cash Payment”). Upon delivery of the All Cash Payment to Holder, all Tranche 1 Warrant Units issued
to Holder in connection with such exercise shall be returned to the Partnership and/or cancelled by
the Partnership.

With respect to the Tranche 2 Warrant Units, if, on the Registration Date, the Registration
Date Price is less than eighty percent (80%) of the Exercise Date Price, the Partnership and Rio
Vista Penny jointly agree to deliver to Holder either (i) Additional Units in such number as
necessary so that the aggregate value (based on the Registration Date Price) of (A) the Tranche 2
Warrant Units issued to Holder in connection with such exercise plus (B) the Additional Units,
equals at least eighty percent (80%) of the value (based on the Exercise Date Price) of the Warrant
Units issued to Holder in connection with such exercise, or (ii) Additional Cash in such amount as
necessary so that the aggregate value of (A) the Tranche 2 Warrant Units (based on the Registration
Date Price) issued to Holder in connection with such exercise plus (B) the Additional Cash, equals
at least eighty percent (80%) of the value (based on the Exercise Date Price) of the Tranche 2
Warrant Units issued to Holder in connection with such exercise. In lieu of delivery of Additional
Units or Additional Cash as provided above, the Partnership and Rio Vista Penny may elect to make
an All Cash Payment to Holder equal to the aggregate value (based on the Exercise Date Price) of
the Tranche 2 Warrant Units issued to Holder in connection with such exercise. Upon delivery of the
All Cash Payment to Holder, all Tranche 2 Warrant Units issued to Holder in connection with such
exercise shall be returned to the Partnership and/or cancelled by the Partnership.

The Partnership shall pay all taxes and other expenses and charges payable in connection with
the preparation, execution, and delivery of unit certificates pursuant to this Section 1
except that, in case such unit certificates shall be registered in a name or names other than
Holder of this Warrant, funds sufficient to pay all transfer taxes which shall be payable in
connection with the execution and delivery of such unit certificates shall be paid by Holder to
the Partnership at the time of the delivery of such unit certificates by the Partnership as
mentioned above.

Section 2.
Certain Actions Prohibited. The Partnership will not, by amendment of
certificate of limited partnership or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities, or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be observed or
performed by it hereunder, but will at all times in good faith assist in the carrying out of all
the provisions of this Warrant and in the taking of all such action as may reasonably be requested
by Holder of this Warrant in order to protect the exercise privilege of Holder of this Warrant
against dilution or other impairment, consistent with the tenor and purpose of this Warrant.

 

-4-

 

Section 3.
Anti-dilution Provisions. The Fixed Tranche 1 Price and the number of
Tranche 1 Warrant Units shall be subject to adjustment from time to time as provided in this
Section 3.

(a) Adjustment
for Change in Capital. If at any time after the date hereof, the
Partnership (i) pays a dividend or makes a distribution on it common units in common units; (ii)
subdivides its outstanding common units into a greater number of common units, (iii) combines its
outstanding common units into a smaller number of common units, (iv) makes a distribution on its
common units in ownership interests other than common units, or (v) issues by reclassification of
its common units any ownership interests of the Partnership, then the Fixed Tranche 1 Price in
effect immediately prior to such action shall be adjusted so that Holder may receive upon exercise
or exchange of this Warrant and payment of the same aggregate consideration, the number of common
units of the Partnership which Holder would have owned immediately following such action if Holder
had exercised or exchange the Warrant for the Tranche 1 Warrant Units immediately prior to such
action. The adjustment shall become effective immediately after the record date in the case of a
dividend or distribution and immediately after the effective date in the case of a subdivision,
combination, or reclassification.

(b) Adjustment
for Other Distributions. If at any time after the date hereof, the
Partnership distributes to all holders of its common units any of its assets or debt securities,
the Fixed Tranche 1 Price following the record date shall be adjusted to be equal to the product of
(i) the Tranche 1 Exercise Price immediately prior to the adjustment multiplied by (ii) (A) (x) the
Market Price per common unit on the record date of the distribution minus (y) the aggregate fair
market value (as determined by the general partner of the Partnership) on the record date of the
assets or debt securities to be distributed divided by the number of outstanding common units on
such date, divided by (B) the Market Price per common unit on the record date of the distribution.

The adjustment shall be made successively whenever any such distribution is made and shall
become effective immediately after the record date for the determination of unitholders entitled
to receive the distribution. In the event that such distribution is not actually made, the Tranche
1 Exercise Price shall again be adjusted to the Tranche 1 Exercise Price as determined without
giving effect to the calculation provided hereby. In no event shall the Tranche 1 Exercise Price
be adjusted to an amount less than zero.

This subsection (b) does not apply to cash distributions paid in the ordinary course
of business or paid pursuant to Section 6.3 or 6.4 of the Partnership’s First Amended and Restated
Agreement of Limited Partnership.

(c) Minimum
Adjustment of Tranche 1 Exercise Price. If the amount of any adjustment
of the Tranche 1 Exercise Price required pursuant to this Section 3 would be less than one
percent (1%) of the Tranche 1 Exercise Price in effect at the time such adjustment is otherwise so
required to be made, such amount shall be carried forward and adjustment with respect thereto made
at the time of and together with any subsequent adjustment which, together with such amount and any
other amount or amounts so carried forward, shall aggregate at least one percent (1%) of such
Tranche 1 Exercise Price; provided that, upon the exercise of this Warrant, all adjustments carried
forward and not theretofore made up to and including the date of
such exercise shall, with respect to the portion of this Warrant then exercised, be made to the
nearest .001 of a cent.

 

-5-

 

(d) Notice
of Adjustment. Upon the occurrence of any event requiring an adjustment of
the Tranche 1 Exercise Price, then and in each such case, the Partnership shall promptly deliver to
Holder of this Warrant a notice stating the Tranche 1 Exercise Price resulting from such adjustment
and the increase or decrease, if any, in the number of common units issuable upon exercise of this
Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such
calculation is based. Within 90 days after each fiscal year in which any such adjustment shall have
occurred, or within 30 days after any request therefor by Holder of this Warrant stating that
Holder contemplate exercise of this Warrant, the Partnership will deliver to Holder of this Warrant
a certificate of the chief financial officer of the Partnership’s general partner confirming the
statements in the most recent notice delivered under this Section 3(d).

Section 4.
Fundamental Change Transaction. In case at any time after the date hereof
a purchase, tender, or exchange offer shall have been made to and accepted by the holders of more
than 50% of the outstanding common units, or the Partnership is otherwise a party to any
transaction (including, without limitation, a merger, consolidation, sale of all or substantially
all the Partnership’s assets, liquidation, or recapitalization of the common units) which is to be
effected in such a way that as a result of such transaction or offer the holders of common units
(or any other securities of the Partnership then issuable upon the exercise of this Warrant) shall
be entitled to receive stock or other securities or property (including cash) with respect to or
in exchange for common units (or such other securities), (each such transaction being herein
called a “Fundamental Change Transaction”), then, as a condition of such Fundamental Change
Transaction, lawful and adequate provision shall be made whereby Holder of this Warrant shall
thereafter have a warrant that gives them the right to purchase and receive upon the basis and
upon the terms and conditions specified in this Warrant, and in lieu of the common units (or such
other securities) purchasable immediately before such transaction upon the exercise hereof, such
stock or other securities or property (including cash) as may be issuable or payable with respect
to or in exchange for a number of outstanding common units (or such other securities) equal to the
number of common units (or such other securities) purchasable immediately before such transaction
upon the exercise hereof, had such Fundamental Change Transaction not
taken place. In any such
case appropriate provision shall be made with respect to the rights and interests of Holder of
this Warrant to the end that the provisions hereof (including, without limitation, the provisions
for adjustments of the Tranche 1 Exercise Price and of the number of Tranche 1 Warrant Units
purchasable upon exercise hereof) shall thereafter be applicable, as nearly as reasonably may be,
in relation to the stock or other securities or property thereafter deliverable upon the exercise
hereof (including an immediate adjustment of the Tranche 1 Exercise Price if by reason of or in
connection with such Fundamental Change Transaction any securities are issued or event occurs
which would, under the terms hereof, require an adjustment of the Tranche 1 Exercise Price). In
the event of a consolidation or merger of the Partnership with or into another corporation or
entity as a result of which a greater or lesser number of common units of the surviving
corporation or entity are issuable to holders of common units in respect of the number of shares
of common units outstanding immediately prior to such consolidation or merger, then the Tranche 1
Exercise Price in effect immediately prior to such consolidation or merger shall be adjusted in
the same manner as though there were a subdivision or combination of the outstanding common units.

 

-6-

 

The
Partnership shall not effect any such Fundamental Change Transaction unless prior to or simultaneously with the consummation thereof the successor
corporation or entity (if other than the Partnership) resulting from such consolidation or merger
or the corporation or entity purchasing such assets and any other corporation or entity the shares
of stock or other securities or property of which are receivable thereupon by Holder of this
Warrant shall expressly assume, by written instrument executed and delivered (and satisfactory in
form) to Holder of this Warrant, (i) the obligation to deliver to Holder such stock or other
securities or property as, in accordance with the foregoing provisions, Holder may be entitled to
purchase and (ii) all other obligations of the Partnership hereunder.

Section 5.
Other Notices. In case at any time:

(a) the Partnership shall declare or pay to all the holders of common units or other equity
securities any dividend (whether payable in common units, cash, securities or other property),
other than cash distributions pursuant to Section 6.3 or 6.4 of the Partnership’s First Amended and
Restated Agreement of Limited Partnership;

(b) the Partnership shall offer for subscription pro rata to all the holders of common units
any additional equity interests of any class or other rights;

(c) there shall be any capital reorganization, or reclassification of the common units of the
Partnership, or consolidation or merger of the Partnership with, or sale of all or substantially
all its assets to, another corporation or other entity;

(d) there shall be a voluntary or involuntary dissolution, liquidation, or winding-up of the
Partnership; or

(e) there shall be any other Fundamental Change Transaction;

then, in any one or more of such cases, the Partnership shall give to Holder of this Warrant (i)
at least 15 days prior to any event referred to in clause (a) above, at least 30 days
prior to any event referred to in clause (b), (c), (d) or (e)
above, written notice of the date on which the books of the Partnership shall close or a record
shall be taken for such dividend, distribution, or subscription rights or for determining rights
to vote in respect of any such reorganization, reclassification, consolidation, merger, sale,
dissolution, liquidation, winding-up, or transaction and (ii) in the case of any such
reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation,
winding-up, or transaction known to the Partnership, at least 30 days prior written notice of the
date (or, if not then known, a reasonable approximation thereof by the Partnership) when the same
shall take place. Such notice in accordance with the foregoing clause (i) shall also
specify, in the case of any such dividend, distribution, or subscription rights, the date on which
such holders of common units shall be entitled thereto, and such notice in accordance with the
foregoing clause (ii) shall also specify the date on which such holders of common units
shall be entitled to exchange their common units for securities or other property deliverable upon
such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation,
winding-up, or transaction, as the case may be. Such notice shall also state that the action in
question or the record date is subject to the effectiveness of a registration statement under
Securities Laws, or to a favorable vote of security holders, if either is required.

 

-7-

 

Section 6.
Certain Events. If any event occurs as to which, in the good faith judgment
of the general partner of the Partnership, the other provisions of Section 3 or Section 4
are not strictly applicable or if strictly applicable would not fairly protect the exercise
rights of Holder of this Warrant in accordance with the essential intent and principles of such
provisions, then the general partner of the Partnership shall make such adjustment, if any, on a
basis consistent with such essential intent and principles, necessary to preserve, without
dilution, the rights of Holder of this Warrant; provided that no such adjustment shall have the
effect of increasing the aggregate purchase price of the Warrant Units.

Section 7.
Issue Tax. The issuance of certificates for Warrant Units upon the
exercise of this Warrant shall be made without charge to Holder of this Warrant or such shares for
any issuance tax in respect thereof, provided that the Partnership shall not be required to pay
any tax which may be payable in respect of any transfer involved in the issuance and delivery of
any warrant or certificate in a name other than Holder of this Warrant.

Section 8. No Rights or Liabilities as a Partner. This Warrant shall not entitle
Holder to any voting rights or other rights as a partner of the Partnership. No provision of this
Warrant, in the absence of affirmative action by Holder to purchase Warrant Units, and no mere
enumeration herein of the rights or privileges of Holder, shall give rise to any liability of
Holder for the Tranche 1 Exercise Price or Tranche 2 Exercise Price or as a partner of the
Partnership, whether such liability is asserted by the Partnership or by creditors of the
Partnership.

Section 9. Transfer, Exchange, and Replacement of Warrant; Representations and
Covenants.

(a) Warrant
Transferable. Holder of this Warrant may transfer and assign it to any
affiliate of Holder, provided that such person is an “accredited investor” within the meaning of
Rule 501 of Regulation D promulgated under the Securities Act, as presently in effect, or a
Qualified Institutional Buyer (as defined in Rule 144A promulgated under the Securities Act, as
presently in effect). Holder of this Warrant may not transfer and assign it to any other person
without the prior written consent of the Partnership. The permitted or approved transfer of this
Warrant and all rights hereunder, in whole or in part, is registrable at the office or agency of
the Partnership referred to in Section 9(e) by Holder in person or by his duly authorized
attorney, upon surrender of this Warrant properly endorsed. Upon any permitted or approved
transfer of this Warrant to any person, other than a person who is at that time a holder of other
Warrants, the Partnership shall have the right to require Holder and the transferee to make
customary representations to the extent reasonably necessary to assure that the transfer will
comply with the Securities Act and any applicable state securities laws. Holder of this Warrant,
by taking or holding the same, consents and agrees that this Warrant, when endorsed in blank,
shall be deemed negotiable, and that Holder, when this Warrant shall have been so endorsed, may be
treated by the Partnership and all other persons dealing with this Warrant as the absolute owner
and Holder for any purpose and as the person entitled to exercise the rights represented by this
Warrant and to the registration of transfer hereof on the books of the Partnership; but until due
presentment for registration of transfer on such books the Partnership may treat the registered
Holder as the owner and holder of this Warrant for all purposes, and the Partnership shall not be
affected by any notice to the contrary.

 

-8-

 

(b) Warrant
Exchangeable for Different Denominations. This Warrant is
exchangeable, upon the surrender of this Warrant by Holder at the office or agency of the
Partnership referred to in Section 9(e) hereof, for new Warrants of like tenor representing
in the aggregate the right to purchase the number of common units which may be purchased hereunder,
each of such new Warrants to be imprinted with the same legend appearing on the face of this
Warrant and to represent the right to purchase such number of common units as shall be designated
by Holder at the time of such surrender. For purposes hereof, the term “Warrant” shall be deemed
to include any and all such replacement Warrants, whether issued pursuant to this Section
9(b) or any other Section hereof.

(c) Replacement of Warrant. Upon receipt of evidence reasonably satisfactory to the
Partnership of the loss, theft, destruction, or mutilation of this Warrant and, in the case of any
such loss, theft, or destruction, upon delivery of an indemnity agreement reasonably satisfactory
in form and amount to the Partnership, or, in the case of any such mutilation, upon surrender and
cancellation of this Warrant, the Partnership, at its expense, will execute and deliver, in lieu
thereof, a new Warrant of like tenor.

(d) Cancellation; Payment of Expenses. Upon the surrender of this Warrant in
connection with any transfer, exchange, or replacement as provided in Section 9(c), this
Warrant shall be promptly cancelled by the Partnership. The Partnership shall pay all taxes (other
than securities transfer taxes) and all other expenses and charges payable in connection with the
preparation, execution, and delivery of Warrants pursuant to this Section 9.

(e) Register. The Partnership shall maintain, at its office in El Segundo, California
(or such other office or agency of the Partnership as it may designate by notice to Holder), a
register for this Warrant, in which the Partnership shall record the name and address of the person
in whose name this Warrant has been issued, as well as the name and address of each transferee and
each prior owner of this Warrant.

(f) Reservation of Authorized Common Units. The Partnership has, and shall continue
at all times to reserve and keep available out of the aggregate of its authorized but unissued
common units, free and clear of all preemptive rights, such number of its duly authorized common
units, or other stock or securities deliverable pursuant to Section 3 hereof, as shall be
sufficient to enable the Partnership at any time to fulfill all of its obligations hereunder upon
the exercise of this Warrant.

(g) Representations and Covenants of the Partnership. The Partnership represents and
covenants that all Warrant Units will, when issued, be validly issued, fully paid and
nonassessable. Upon the exercise of this Warrant, the issuance of the Warrant Units will not be
subject to any preemptive or similar rights. The Partnership further represents that all securities
previously offered or sold by the Partnership which were not registered pursuant to the Securities
Act or the Securities Exchange Act of 1934, as amended, were offered or sold pursuant to valid
exemptions from the Securities Act. No private offering memorandum furnished to any offeree or
purchaser of such securities, at the time of delivery of such private offering memorandum,
contained any untrue statement of a material fact or omitted to state any material fact required to
be stated therein or necessary in order to make the statements contained therein, in light of the
circumstances under which they were made, not misleading.

(h) Representations and Covenants of Holder. Holder is acquiring this Warrant and will
acquire the Warrant Units for its own account, with no present intention of distributing or
reselling this Warrant or the Warrant Units or any part thereof in violation of applicable
securities laws. Subject to Section 1 hereof, Holder acknowledges that this Warrant has not
been, and when issued the Warrant Units will not be, registered under the Securities Act or the
securities laws of any state in the United States or any other jurisdiction and may not be offered
or sold by such Holder unless subsequently registered under the Securities Act (if applicable to
the transaction) and any other securities laws or unless exemptions from the registration or other
requirements of the Securities Act and any other securities laws are available for the transaction.
Holder represents that it is an “accredited investor” within the meaning of Rule 501 of Regulation
D promulgated under the Securities Act, as presently in effect, or a Qualified Institutional Buyer
(as defined in Rule 144A promulgated under the Securities Act, as presently in effect).

Attention:
                                        

The undersigned, Holder of the foregoing Warrant, hereby elect to exercise purchase
rights represented thereby for, and to purchase thereunder,                      common units covered by
such Warrant pursuant to Section 1 of such Warrant, herewith makes payment in full for such common
units by reducing the outstanding principal, accrued interest, and other expenses owing
to Holder by GMOP pursuant to the Note Purchase Agreement by $                     and request that
certificates for such common units (and any other securities or other property issuable upon such
exercise) be issued in the name of, and delivered to                                          and                                         .

The undersigned, Holder of the foregoing Warrant, is acquiring such common units for its own
account, with no present intention of distributing or reselling such units or any part thereof in
violation of applicable securities laws. Subject to Section 1 of such Warrant, Holder acknowledges
that such units have not been registered under the Securities Act of 1933 (the “Securities Act”)
or the securities laws of any state in the United States or any other jurisdiction and may not be
offered or sold by such Holder unless subsequently registered under the Securities Act (if
applicable to the transaction) and any other securities laws or unless exemptions from the
registration or other requirements of the Securities Act and any other securities laws are
available for the transaction. Holder represents that it is an “accredited investor” within the
meaning of Rule 501 of Regulation D promulgated under the Securities Act, as presently in effect,
or a Qualified Institutional Buyer (as defined in Rule 144A promulgated under the Securities Act,
as presently in effect).
