--------------------------------------------------------------------------------

Agreement

Section 1. Board Observation Rights.

(a) During the period commencing upon the execution and delivery of this
Agreement and ending on the Board Rights Termination Date (defined below), the
Crestwood Entities shall grant the Purchasers, collectively, the option and
right, exercisable, upon written approval of a majority of the then outstanding
Preferred Units held, directly or indirectly, by the Purchasers (in the
aggregate), by delivering a written notice signed by such Purchasers of such
appointment to the Crestwood Entities (the “Observer Notice”), to appoint a
single representative, who shall be employed by one of the Purchasers (or their
Affiliates) at the time of such appointment (the “Board Observer”), to attend
all meetings (including telephonic) of the full Board in an observer capacity.
The Observer Notice shall be delivered to the Crestwood Entities prior to the
Board Observer’s attendance of any meeting of the full Board. The Board Observer
shall not constitute a member of the Board and shall not be entitled to vote on,
or consent to, any matters presented to the Board. For the avoidance of doubt,
the Board Observer shall have no right to attend any meeting of any committee of
the full Board (each, a “Committee”); provided, however, the Crestwood Entities
shall (i) give the Board Observer written notice of the applicable meeting or
action taken by written consent of such Committee at the same time and in the
same manner as notice is given to the members of such Committee and (ii) with
respect to the Audit Committee and the Compensation Committee of the Board,
provide the Board Observer with copies of all written materials and other
information (including, without limitation, copies of minutes of meetings or
written consents of such Committee) given to the members of the Audit Committee
and the Compensation Committee in connection with such meetings or actions taken
by written consent at the same time such materials and information are furnished
to such members of the Audit Committee and the Compensation Committee.

(b) The Crestwood Entities shall (i) give the Board Observer written notice of
the applicable meeting or action taken by written consent at the same time and
in the same manner as notice is given to the members of the Board, (ii) provide
the Board Observer with copies of all written materials and other information
(including, without limitation, copies of minutes of meetings or written
consents of the full Board) given to the members of the Board in connection with
such meetings or actions taken by written consent at the same time such
materials and information are furnished to such members of the Board, and
(iii) provide the Board Observer with all rights to attend (whether in person or
by telephone or other means of electronic communication as solely determined by
the Board Observer) such meetings as a member of the Board. The Board Observer
shall agree to maintain the confidentiality of all non-public information and
proceedings of the Board and to enter into, comply with, and be bound by, in all
respects, the terms and conditions of a confidentiality agreement, substantially
in the form attached hereto as Annex A (the “Confidentiality Agreement”);
provided, however, upon request from a Purchaser or such Purchaser’s Affiliates,
the Board Observer shall provide, on a confidential basis, such non-public
material and information to such Purchaser and their Affiliates; provided that
such Purchaser and their Affiliates have agreed to comply with and be bound by,
in all respects, the Confidentiality Agreement. For the avoidance of doubt, the
recipient of such confidential information from the Board Observer (whether a
Purchaser or a Purchaser Affiliate) may further provide such information to
(i) any other Purchaser or Purchaser Affiliate and (ii) any legal counsel that
has been engaged by such recipient to discuss such matters or information;
provided, that any such

--------------------------------------------------------------------------------

recipient in clause (i) or (ii) agrees and acknowledges in writing that they are
bound by the provisions of the Confidentiality Agreement. For purposes of this
Agreement, “Affiliates” shall have the same meaning ascribed therefor in the
Purchase Agreement. Notwithstanding any rights to be granted or provided to the
Board Observer hereunder, the Crestwood Entities reserve the right to exclude
the Board Observer from access to any material or meeting or portion thereof if
the Board reasonably determines, in good faith, that such access would
(A) prevent the members of the Board from engaging in attorney-client privileged
communication or (B) result in a conflict of interest with any Purchaser;
provided, however, that such exclusion shall be limited to the portion of the
material and/or meeting that is the basis for such exclusion and shall not
extend to any portion of the material and/or meeting that does not involve or
pertain to such exclusion. The Purchaser then employing the Board Observer
agrees to indemnify the Crestwood Entities from any and all costs, losses,
liabilities, damages, or expenses of any kind or nature whatsoever arising from
the breach by the Board Observer of the confidentiality obligations under the
Confidentiality Agreement or this Section 1.

(c) The rights contained in this Section 1 shall immediately cease and terminate
on the earlier of such date (such earlier date, the “Board Rights Termination
Date”) as the Purchasers and their respective Affiliates no longer own (i) at
least 75% of the Purchased Units (as defined in the Purchase Agreement) or
(ii) a number of Preferred Units, which, if they were converted into Common
Units at the then applicable Conversion Ratio (as defined in Amendment No. 3),
subject to appropriate adjustments for splits, combinations and other similar
transactions, would be equal to 5% or more of the total number of Common Units
then outstanding. From and after the Board Rights Termination Date, the rights
of the Purchasers in Sections 1(a) and 1(b) shall cease.

Section 2. Board Designation Rights.

(a) If the Class A Preferred Distribution Amount (as such term is defined in
Amendment No. 3) is not paid in full in cash to the holders of outstanding
Preferred Units (as such term is defined in Amendment No. 3) for two consecutive
calendar quarters that commence after the Initial Distribution Period (as
defined in Amendment No. 3) (such failure, the “Designation Right Triggering
Event”), then, until the Designation Right Termination Event (defined below),
the Purchasers shall have the option and right, exercisable, upon written
approval of a majority of the then outstanding Preferred Units held, directly or
indirectly, by the Purchasers (in the aggregate), by delivering a written notice
of such designation to the Crestwood Entities, to designate one person to serve
on the Board (the “Purchaser Designated Director”) and the Crestwood Entities
shall take all actions necessary or advisable to effect the foregoing; provided,
however, that such Purchaser Designated Director shall, in the reasonable
judgment of the General Partner, (i) have the requisite skill and experience to
serve as a director of a public company, (ii) not be prohibited from serving as
a director pursuant to any rule or regulation of the Securities and Exchange
Commission (the “Commission”) or any national securities exchange on which the
Partnership’s Common Units are listed or admitted to trading, and (iii) not be
an employee or director of any Competitor (as defined below). For purposes of
the immediately preceding sentence the term “Competitor” shall mean any person
or entity that (a) is an operating company (and not a financial institution) and
(b) engages in the midstream energy business or otherwise provides similar
services or engages in similar business as the Partnership. The Purchasers agree
upon the Partnership’s request to timely provide the Partnership with accurate
and complete

--------------------------------------------------------------------------------

information relating to the Purchaser Designated Director as may be required to
be disclosed by the Partnership under the Securities and Exchange Act of 1934,
as amended (the “Exchange Act”) and the rules and regulations promulgated
thereunder. Prior to a Designation Right Termination Event (as defined below),
the Purchaser Designated Director may be removed or replaced by the Purchasers
at any time and by Crestwood Midstream Holdings LP, the sole member of the
General Partner, for “cause” (as defined below), but not by any other Party; and
any vacancy occurring by reason of the death, disability, resignation, removal
or other cessation of a person serving as Purchaser Designated Director, shall
be filled solely by the Purchasers. As used herein, “cause” means that the
Purchaser Designated Director (i) is prohibited from serving as a director under
any rule or regulation of the Commission or any national securities exchange on
which the Partnership’s Common Units are listed; (ii) while serving as the
Purchaser Designated Director is convicted by a court of competent jurisdiction
of a felony; (iii) a court of competent jurisdiction has entered, a final,
non-appealable judgment finding the Purchaser Designated Director liable for
actual fraud or willful misconduct against the Partnership (including, but not
limited to, intentionally or wilfully failing to observe the obligation of
confidentiality contained in Section 1(b) of this Agreement); (iv) is determined
to have acted intentionally or in bad faith in a manner that results in a
material detriment to the assets, business or prospects of the Partnership or
(v) is terminated, removed or resigns for any reason from his or her position,
if any, with any such Purchaser at which the Purchaser Designated Director is
then employed. Any action by the Purchasers to designate, remove or replace a
Purchaser Designated Director shall be evidenced in writing furnished to the
Crestwood Entities, shall include a statement that the action has been approved
by the Purchasers and shall be executed by or on behalf of the Purchasers. While
serving as a Purchaser Designated Director, a Purchaser Designated Director
(i) shall be entitled to vote on any matter on which independent members of the
Board are entitled to vote on (unless prohibited by the rules and regulations of
the Securities and Exchange Commission or the New York Stock Exchange),
provided, however, in connection with any matter that could adversely affect the
rights, powers, privileges, preferences, duties or obligations of the Preferred
Units, the Purchaser Designated Director shall consult with all Purchasers that
hold, directly or indirectly, then outstanding Preferred Units, prior to such
Purchaser Designated Director approving such matter in his or her capacity as a
Board member; and (ii) shall be entitled to compensation commensurate with that
of an independent member of the Board and reimbursed for reasonable expenses.

(b) Upon payment by the Partnership to the Purchasers of all accrued but unpaid
distributions on the Preferred Units then outstanding (a “Designation Right
Termination Event”), the right of the Purchasers to designate a Purchaser
Designated Director shall automatically terminate and the Purchasers shall cause
the Purchaser Designated Director then serving as a member of the Board,
promptly upon (and in any event within two (2) Business Days following) receipt
of a written request from the Partnership, to resign as a member of the Board.
If the Purchaser Designated Director does not resign upon such request, then a
majority of the other director(s) then serving on the Board may remove the
Purchaser Designated Director as a member of the Board.

Section 3. Limitation of Liability; Indemnification; Business Opportunities.

(a) At all times while the Purchaser Designated Director is serving as a member
of the Board, and following any such Purchaser Designated Director’s death,
resignation, removal or other cessation as a director in such former Purchaser
Designated Director’s capacity as a former

--------------------------------------------------------------------------------

director, the Purchaser Designated Director shall be entitled to (i) the same
modification and restriction of traditional fiduciary duties, (ii) the same safe
harbors for resolving conflicts of interest transactions and (iii) all rights to
indemnification and exculpation, in each case, as are then made available to any
other member of the Board.

(b) For the avoidance of doubt, the Board Observer shall have (i) no fiduciary
duty to the Crestwood Entities or to any Limited Partner (as defined in the
Partnership Agreement) and (ii) no obligations to the Crestwood Entities under
this Agreement, except as described in Section 1 of this Agreement, or to any
Limited Partner.

(c) At all times while the Purchaser Designated Director is serving as a member
of the Board or the Board Observer is serving in such capacity in accordance
with Section 1 of this Agreement, such Purchaser Designated Director or Board
Observer, the Purchasers and their respective Affiliates may engage in, possess
an interest in, or trade in the securities of, other business ventures of any
nature or description, independently or with others, similar or dissimilar to
the business of the Crestwood Entities, and the Crestwood Entities, the Board
and their Affiliates shall have no rights by virtue of this Agreement in and to
such independent ventures or the income or profits derived therefrom, and the
pursuit of any such venture, even if competitive with the business of the
Crestwood Entities, shall not be deemed wrongful or improper. None of the
Purchaser Designated Director, the Board Observer, the Purchasers or their
respective Affiliates shall be obligated to present any investment opportunity
to the Crestwood Entities even if such opportunity is of a character that the
Crestwood Entities or any of their respective subsidiaries might reasonably be
deemed to have pursued or had the ability or desire to pursue if granted the
opportunity to do so, and each of the Purchaser Designated Director, the Board
Observer, the Purchasers or their respective Affiliates shall have the right to
take for such person’s own account (individually or as a partner or fiduciary)
or to recommend to others any such investment opportunity. Notwithstanding the
foregoing, the Purchaser Designated Director and the Board Observer shall be
subject to, and comply with, the requirement to maintain confidential
information pursuant to this Agreement.

(d) The Crestwood Entities shall purchase and maintain (or reimburse the
Purchaser Designated Director for the cost of) insurance (“D&O Insurance”), on
behalf of the Purchaser Designated Director, against any liability that may be
asserted against, or expense that may be incurred by, such Purchaser Designated
Director in connection with Crestwood Entities’ activities or such Purchaser
Designated Director’s activities on behalf of the Crestwood Entities, regardless
of whether the Crestwood Entities would have the power to indemnify such
Purchaser Designated Director against such liability under the provisions of the
Partnership Agreement or the First Amended and Restated Limited Liability
Company Agreement of the General Partner (the “GP LLC Agreement. Such D&O
Insurance shall provide coverage commensurate with that of an independent member
of the Board.

(e) For the avoidance of doubt, the Purchaser Designated Director shall
constitute an “Indemnitee,” as such term is defined under the Partnership
Agreement and the GP LLC Agreement.

--------------------------------------------------------------------------------

Section 4. Standstill.

(a) During the period commencing on the Initial Closing Date and ending on the
third anniversary thereof, without the prior written consent of the Partnership
(provided that such consent shall not be required in the event of fraud or gross
negligence on the part of the Partnership or the General Partner), the holders
of Preferred Units and their Affiliates will not, directly or indirectly:

(i) Enter into any transaction the effect of which would be to “short” any
securities of the Partnership;

(ii) Call (or participate in a group calling) a meeting of the limited partners

regulations of the Commission) or votes for or in support of (A) the removal of
the General Partner as the general partner of the Partnership or (B) the
election of any successor general partner of the Partnership, or take any action
the direct effect or purpose of which would be to induce limited partners of the
Partnership to vote or provide proxies that may be voted in favor of any action
contemplated by either of sub-clauses (A) or (B) of this Section 4(a)(iii);

(iv) Seek to advise or influence any person (within the meaning of
Section 13(d)(3) of the Exchange Act) with respect to the voting of any limited
partner interests of the Partnership in connection with the removal (or
approving the removal) of the General Partner as the general partner of the
Partnership and/or the election of a successor general partner of the
Partnership;

(v) Issue, induce or assist in the publication of any press release, media
report or other publication in connection with the potential or proposed removal
of the General Partner as the general partner of the Partnership and/or the
election of a successor general partner of the Partnership;

(vi) Instigate or encourage any third party to do any of the foregoing; or

(vii) If the General Partner is removed as the general partner of the
Partnership, participate in any way in the management, ownership and/or control
of the managing general partner or the successor general partner’s operation of
the Partnership, other than participation by a Purchaser Designated Director or
Board Observer, as described in Sections 1 and 2 of this Agreement.

(b) Notwithstanding anything to the contrary in this Agreement, (i) the
foregoing shall not in any way limit the right of the Purchasers or their
Affiliates to vote their limited partner interests in the Partnership at any
meeting of limited partners of the Partnership so long as there has been no
breach of Section 4(a) of this Agreement; and (ii) for purposes of Section 4(a)
of this Agreement, “Affiliates” of GSO COF II Holdings Partners LP shall include
any fund managed or advised by GSO Capital Partners LP or its Affiliates;
provided, however, that, in each such case, such fund falls within the credit
business of The Blackstone Group LP.

action shall be in such Party’s sole discretion, unless otherwise specified in
this Agreement. If any provision in this Agreement is held to be illegal,
invalid, not binding or unenforceable, (i) such provision shall be fully
severable and this Agreement shall be construed and enforced as if such illegal,
invalid, not binding or unenforceable provision had never comprised a part of
this Agreement, and the remaining provisions shall remain in full force and
effect and (ii) the Parties hereto shall negotiate in good faith to modify this

causes of action (whether in contract or tort) that may be based upon, arise out
of or relate to this Agreement or the negotiation, execution or performance of
this Agreement (including any claim or cause of action based upon, arising out
of or related to any representation or warranty

irrevocably submit to the non-exclusive jurisdiction of any federal or state
court located within the State of Delaware over any such action. Each of the
Parties hereby irrevocably waives, to the fullest extent permitted by applicable
Law, any objection that it may now or hereafter have to the laying of venue of
any such dispute brought in such court or any defense of inconvenient forum for
the maintenance of such dispute. Each of the Parties hereto agrees that a
judgment in any such dispute may be enforced in other jurisdictions by suit on
the judgment or in any other manner provided by Law.

(e) Waiver of Jury Trial. EACH OF THE PARTIES TO THIS AGREEMENT HEREBY WAIVES,
AND AGREES TO CAUSE ITS AFFILIATES TO WAIVE, TO THE FULLEST EXTENT PERMITTED BY
LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION

INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT OR
ANY OF THE TRANSACTIONS RELATED HERETO, IN EACH CASE WHETHER NOW EXISTING OR
HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY OR OTHERWISE. EACH OF
THE PARTIES TO THIS AGREEMENT HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY
AND THAT THE PARTIES TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OF A
COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE
PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

(f) No Waiver; Modifications in Writing.

(i) Delay. No failure or delay on the part of any Party in exercising any right,
power or remedy hereunder shall operate as a waiver thereof, nor shall any
single or partial exercise of any such right, power or remedy preclude any other
or further exercise thereof or the exercise of any other right, power or remedy.
The remedies provided for herein are cumulative and are not exclusive of any
remedies that may be available to a Party at law or in equity or otherwise.

(ii) Specific Waiver. Except as otherwise provided herein, no amendment, waiver,
consent, modification or termination of any provision of this Agreement shall be
effective unless signed by each of the Parties hereto affected by such
amendment, waiver, consent, modification or termination. Any amendment,
supplement or modification of or to any provision of this Agreement, any waiver
of any provision of this Agreement and any consent to any departure by a Party
from the terms of any provision of this Agreement shall be effective only in the
specific instance and for the specific purpose for which made or given. Except
where notice is specifically required by this Agreement, no notice to or demand
on a Party in any case shall entitle such Party to any other or further notice
or demand in similar or other circumstances. Any investigation by or on behalf
of any Party shall not be deemed to constitute a waiver by the Party taking such
action of compliance with any representation, warranty, covenant or agreement
contained herein.

--------------------------------------------------------------------------------

(g) Execution in Counterparts. This Agreement may be executed in any number of
counterparts and by different Parties hereto in separate counterparts, each of
which counterparts, when so executed and delivered, shall be deemed to be an
original and all of which counterparts, taken together, shall constitute one and
the same agreement.

(h) Binding Effect; Assignment. This Agreement will be binding upon and inure to
the benefit of the Parties hereto and their respective successors and permitted
assigns, but will not be assignable or delegable by any Party hereto without the
prior written consent of each of the other Parties; provided, that the terms and
provisions of this Agreement shall not be effective or binding upon a Purchaser
that has transferred all of its Preferred Units to a third-party and, upon such
transfer, the rights of such Purchaser under this Agreement shall terminate and
cease.

(i) Independent Counsel. Each of the Parties acknowledges that it has been
represented by independent counsel of its choice throughout all negotiations
that have preceded the execution of this Agreement and that it has executed the
same with consent and upon the advice of said independent counsel. Each Party
and its counsel cooperated in the drafting and preparation of this Agreement and
the documents referred to herein, and any and all drafts relating thereto will
be deemed the work product of the Parties and may not be construed against any
Party by reason of its preparation. Accordingly, any rule of Law or any legal
decision that would require interpretation of any ambiguities in this Agreement
against the Party that drafted it is of no application and is hereby expressly
waived.

(j) Specific Enforcement. Each of the Parties acknowledges and agrees that
monetary damages would not adequately compensate an injured Party for the breach
of this Agreement by any Party, that this Agreement shall be specifically
enforceable and that any breach or threatened breach of this Agreement shall be
the proper subject of a temporary or permanent injunction or restraining order
without a requirement of posting bond. Further, each Party hereto waives any
claim or defense that there is an adequate remedy at law for such breach or
threatened breach.

(k) Transfer of Board Rights; Aggregation. The option and right to appoint a
Board Observer or Purchaser Designated Director granted to the Purchasers by the
Partnership under Sections 1 and 2, respectively, of this Agreement, may be
transferred or assigned by any Purchaser to one or more of its Affiliates,
subject to the transfer restrictions provided in Section 4.7(d) of the
Partnership Agreement, provided, however, that (a) the Partnership is given
written notice prior to any said transfer or assignment, stating the name and
address of each of the transferee or assignee and identifying the securities
with respect to which such rights are being transferred or assigned and (b) each
such transferee or assignee assumes in writing responsibility for its portion of
the obligations of such Purchaser under this Agreement. All Preferred Units held
or acquired by Persons (as defined in the Partnership Agreement) who are
Affiliates of one another shall be aggregated together for the purpose of
determining the availability of any rights and applicability of any obligations
under this Agreement.

--------------------------------------------------------------------------------

(l) Further Assurances. Each of the Parties hereto shall, from time to time and
without further consideration, execute such further instruments and take such
other actions as any other Party hereto shall reasonably request in order to
fulfill its obligations under this Agreement to effectuate the purposes of this
Agreement.

Crestwood Midstream GP LLC

Attn:

Dear Ladies and Gentlemen:

substantially the form hereof. The Board Observer acknowledges that at the
meetings of the Board and at other times the Board Observer may be provided with
and otherwise have access to non-public information concerning the Crestwood
Entities and their Affiliates. Capitalized terms used but not otherwise defined
herein, shall have the respective meanings ascribed therefor in the Board
Representation and Standstill Agreement. In consideration for and as a condition
to the Crestwood Entities furnishing access to such information, the Board
Observer hereby agrees to the terms and conditions set forth in this letter
agreement (the “Agreement”):

1. As used in this Agreement, subject to Paragraph 3 below, “Confidential
Information” means any and all non-public financial or other non-public
information concerning the Crestwood Entities and their Affiliates that may
hereafter be disclosed to the Board Observer by the Crestwood Entities, their
Affiliates or by any of their directors, officers, employees, agents,
consultants, advisors or other representatives (including financial advisors,
accountants or legal counsel) (the “Representatives”) of the Crestwood Entities,
including, without limitation, all notices, minutes, consents, materials, ideas
or other information (to the extent constituting information concerning the
Crestwood Entities and their Affiliates that is non-public financial or other
non-public information) provided to the Board Observer.

--------------------------------------------------------------------------------

2. Except to the extent permitted by this Paragraph 2 or by Paragraph 3 or 4,
the Board Observer shall keep such Confidential Information strictly
confidential; provided, that the Board Observer may, upon request from a
Purchaser or such Purchaser’s Affiliates, share Confidential Information with
such Purchaser or such Purchaser’s Affiliates so long as such individuals or
entities agree to comply with, and be bound by, in all respects, the terms of
this Agreement. For the avoidance of doubt, the recipient of such Confidential
Information from the Board Observer may further provide such Confidential
Information to (i) any other Purchaser or Purchaser Affiliate and (ii) any legal
counsel that has been engaged by such recipient to discuss such matters or
Confidential Information; provided, that any such recipient in clause (i) or
(ii) above agrees and acknowledges in writing to be bound by the terms of this
Agreement. The Board Observer may not record the proceedings of any meeting of
the Board by means of an electronic recording device.

3. The term “Confidential Information” does not include information that (i) is
or becomes generally available to the public other than (a) as a result of a
disclosure by the Board Observer in violation of this Agreement or (b) in
violation of a confidentiality obligation to the Crestwood Entities known to the
Board Observer, (ii) is or becomes available to the Board Observer on a
non-confidential basis from a source not known to have an obligation of
confidentiality to the Crestwood Entities, (iii) was already known to the Board
Observer at the time of disclosure, or (iv) is independently developed by the
Board Observer without reference to any Confidential Information disclosed to
the Board Observer.

4. In the event that the Board Observer is legally required or compelled to
disclose the Confidential Information, the Board Observer shall use reasonable
best efforts, to the extent permitted and practicable, to provide the Crestwood
Entities with prompt prior written notice of such requirement so that the
Crestwood Entities may seek, at such entities sole expense and cost, an
appropriate protective order. If in the absence of a protective order, the Board
Observer is nonetheless legally required or compelled to disclose Confidential
Information, the Board Observer may disclose only the portion of the
Confidential Information or other information that it is so legally required or
compelled to disclose.

5. All Confidential Information disclosed by the Crestwood Entities or their
Representatives to the Board Observer is and will remain the property of the
Crestwood Entities, so long as such information remains Confidential
Information.

6. It is understood and acknowledged that neither the Crestwood Entities nor any
Representative makes any representation or warranty as to the accuracy or
completeness of the Confidential Information or any component thereof.

7. It is further understood and agreed that money damages would not be a
sufficient remedy for any breach of this Agreement by the Board Observer and
that the Crestwood Entities shall be entitled to seek specific performance or
any other appropriate form of equitable relief as a remedy for any such breach
in addition to the remedies available to the Crestwood Entities at law.

8. This Agreement is personal to the Board Observer, is not assignable by the
Board Observer and may be modified or waived only in writing. This Agreement is
binding upon the parties hereto and their respective successors and assigns and
inures to the benefit of the parties hereto and their respective successors and
assigns.

--------------------------------------------------------------------------------

9. If any provision of this Agreement is not enforceable in whole or in part,
the remaining provisions of this Agreement will not be affected thereby. No
failure or delay in exercising any right, power or privilege hereunder operates
as a waiver thereof, nor does any single or partial exercise thereof preclude
any other or further exercise thereof or the exercise of any other right, power
or privilege hereunder.

10. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO ANY CHOICE OR CONFLICT
OF LAW PROVISION (WHETHER OF THE STATE OF DELAWARE OR ANY OTHER JURISDICTION)
THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY JURISDICTION OTHER THAN THE
STATE OF DELAWARE.

11. This Agreement and all obligations herein will automatically expire three
(3) years from the date the Board Observer ceases to act as Board Observer.

12. This Agreement may be executed in one or more counterparts, each of which
will be deemed to be an original copy of this Agreement, and all of which, when
taken together, will constitute one and the same agreement. The exchange of
copies of this Agreement and of signature pages by facsimile or electronic
transmission constitutes effective execution and delivery of this Agreement as
to the parties and may be used in lieu of the original Agreement. Signatures of
the parties transmitted by facsimile or electronic transmission will be deemed
to be their original signatures for any purpose whatsoever.
