                    (d)  any one or more of the following:

                         (i)  any person (as such term is used in Sections
13(d) and 14(d) of the Securities Exchange Act of 1934, as amended), other
than as a trustee or other fiduciary holding securities under an employee
benefit plan of the Parent, is or becomes the "beneficial owner" (as

Directors of the Parent and any new directors whose election by the Board

office who either were directors at the beginning of the period or whose
election or nomination for election was previously so approved, cease for
any reason to constitute a majority of the Board of Directors of the
Parent, or

of the Parent outstanding immediately prior to such a merger or
consolidation continuing to represent (either by remaining outstanding or
by being converted into voting securities of the surviving entity) at least
66-2/3% of the total voting power represented by the voting securities of
the Parent or such surviving entity outstanding immediately after such
merger or consolidation, or

                         (iv) the stockholders of the Parent approve a plan

transactions) all or substantially all of the Parent's assets shall be
transferred to a person (as that term is used in Sections 13(d) and 14(d)
of the Securities Exchange Act of 1934, as amended) not wholly owned by the
Parent, or

                         (v)  the Parent shall no longer be the beneficial
owner (as defined in Rule 13d-3 under the Securities Exchange Act of 1934,

MANAGEMENT FEE AND VACATION.  Cornerstone's Board may terminate Executive's
employment with Cornerstone at any time for "cause" as defined below,
immediately upon notice to Executive of the circumstances leading to such
termination for cause.  In the event that Executive's employment is
terminated for cause, Executive shall receive payment for all accrued
salary, Acquisition Management Fee and vacation time through the
Termination Date, which in this event shall be the date upon which notice
of termination is given.  Cornerstone shall have no further obligation to
pay severance of any kind nor to make any payment in lieu of notice.

               ii.  DEFINITION OF CAUSE.  "CAUSE" means the occurrence or

conviction or the plea of nolo contendere or the equivalent in respect to a
felony involving moral turpitude; (c) any intentional damage of a material
nature to any property of Cornerstone, any Partnership or any Additional

to serve in his capacity as employee of Cornerstone.

Executive's employment in the event Executive suffers a disability that
renders Executive unable to perform the essential functions of his
position, even with reasonable accommodation, for nine (9) months within
any twelve (12) month period.  Commencing on the Termination Date, which in
this event shall be the date upon which notice of termination is given,
Cornerstone shall pay Executive an amount equal to that payable upon
termination without cause under paragraph 4(a)(i).

          d.  BENEFITS UPON TERMINATION.  All benefits provided under
paragraph 2(h) hereof shall be extended, to the extent permitted by
Cornerstone's insurance policies and benefit plans, for one (1) year after
Executive's Termination Date, except (a) as required by law (e.g., COBRA
health insurance continuation election), or (b) in the event of a
termination described in paragraph 4(b) if Cornerstone does not decide to
require the noncompetition agreement as described in section 6.

               i.   ANNUAL OPERATING PERFORMANCE INCENTIVE PLAN.  A ratable
portion (based on the days in the fiscal year in which termination occurs
on or before its effective date and the total number of days in the fiscal
year) of the cash award to which Executive would have been entitled under
the Plan for the entire year, which shall be paid in cash no later than
ninety (90) fiscal days after the close of the fiscal year.

               ii.  NEW ACQUISITION INCENTIVE PLAN.  The amount payable for
any addition to the propane operations as to which a letter of intent,
memorandum of understanding or similar document, or the definitive
agreements, were entered into prior to the Termination Date, which shall be
payable if and when the addition is consummated.

               iii. LONG TERM EQUITY INCENTIVE PLAN.  The amount payable in
accordance with the Plan's vesting provisions.

               iv.  RESTRICTED UNITS PLAN.  The amount payable in

confidential and proprietary information, including but not limited to
information or plans regarding customer relationships, personnel, sales,
marketing, and financial operations and methods, trade secrets, formulas,
devices, secret inventions, processes, and other compilations of
information, records, and specifications (collectively, except to the
extent it was already known from other sources, or is or becomes general
knowledge, in each case without known violation of any confidentiality
obligation, "Proprietary Information").  Executive shall not disclose any
of the Proprietary Information directly or indirectly, or use it in any
way, either during the duration of this Agreement or at any time
thereafter, except as required in the course of his employment with
Cornerstone or as authorized in writing by Cornerstone.  All files,
records, documents, computer-recorded information, drawings specifications,
equipment and similar items relating to the business of Cornerstone, the
Partnerships and/or Additional Companies, whether prepared by Executive or
otherwise coming into his possession, shall remain the exclusive property
of Cornerstone, the Partnerships and/or Additional Companies, respectively,
and shall not be removed under any circumstances whatsoever without the
prior written consent of Cornerstone, except when (and only for the period)
necessary to carry out Executive's duties hereunder, and if removed shall
be immediately returned to Cornerstone upon any termination of his
employment and no copies thereof shall be kept by Executive; provided,
however, that Executive shall be entitled to retain documents that were
personally owned or acquired.

     6.  COVENANT NOT TO COMPETE.

               Cornerstone and the Partnerships are presently engaged in
the retail business of selling and distributing propane to end-user
customers in bobtail delivery vehicles with capacities below 5,000 gallons
(the "Business").  The term "Business" shall also include the sale,
distribution, or transport of natural gas liquids, including without
limitation propane, (collectively "NGL's") in transport loads of 5,000
gallons or more, whether for end use or resale, or the rendition of any
services to persons or entities engaged in the business of selling or
distributing NGL's, or the trading, selling, hedging, processing or
otherwise dealing with NGL's or other petroleum products (or contracts for
any of the foregoing) for any purpose.

               Executive agrees that for a twelve (12) month period from
the end of his employment with Cornerstone, he will not carry on the
"Business" with fifty (50) miles of any of the foregoing existing locations
of Cornerstone or the Partnerships.  For purposes of this Agreement,
Executive will be deemed to be "carrying on" the Business if he does so
directly or if he is the owner or an officer or an employee of, a
consultant to or a stockholder or holder of another equity interest in, any
person engaged in the business, provided however, that Executive may own,
directly or indirectly, solely as an investment, securities of any person
traded on a national exchange or listed on the NASDAQ National Market so
long as he does not, directly or indirectly, own 5% or more of the fully
diluted interest in such person.

     7.  NONINTERFERENCE.  While employed by Cornerstone, and during the
time any noncompetition covenant as described under section 6 is in effect,
Executive agrees not to interfere with the business of Cornerstone by
directly or indirectly soliciting, attempting to solicit, inducing, or
otherwise causing any employee of Cornerstone to terminate his or her
employment in order to become an employee, consultant or independent
contractor to or for any other employer.

Dispute Resolution Rules and Regulations of the American Arbitration
Association.  Such disputes shall include, but are not limited to, claims

Agreement may be made except by a writing signed by both parties.  Nothing
in this Agreement, express or implied, is intended to confer upon any third

amendment or waiver of this Agreement requires the consent of any
individual, partnership, corporation or other entity not a party to this
Agreement.
