                             EMPLOYMENT AGREEMENT
                             --------------------

          THIS EMPLOYMENT AGREEMENT (this "Agreement") is entered into this 30th
day of May, 2001, by and between Inergy Partners, LLC, a Delaware limited
liability company (the "Company"), and William C. Gautreaux, an individual (the
"Employee").

          1.   Employment.  The Company agrees to employ the Employee and the
               ----------
Employee agrees to be employed by the Company as the Vice President - Supply
Logistics and Risk Management of the Company upon the terms and conditions of
this Agreement, commencing on the date hereof and continuing until terminated as
provided in Section 11 below. The Employee shall report to the President of the
            ----------
Company.

          2.   Compensation.  For all services rendered by the Employee to the
               ------------
Company, the Company shall pay the Employee a salary at the annual rate of One
Hundred Twenty-Five Thousand Dollars ($125,000) (the "Salary") payable bi-
monthly in arrears. Such Salary shall be reviewed from time to time by the
Company but no less often than annually.

          3.   Expenses.  The Company shall reimburse the Employee for all
               --------
ordinary and necessary expenses incurred and paid by the Employee in the course
of the performance of the Employee's duties pursuant to this Agreement and
consistent with the Company's policies in effect from time to time with respect
to travel, entertainment and other business expenses, and subject to the
Company's requirements with respect to the manner of approval and reporting of
such expenses.

          4.   Additional Benefits.
               -------------------

          (a)  The Employee shall be eligible for such fringe benefits, if any,
     by way of insurance, hospitalization and vacations normally provided to
     other members of the executive management of the Company generally and such
     additional benefits as may be from time to time agreed upon in writing
     between the Employee and the Company.

          (b)  It is expected that during fiscal year 2001, the Company will
     have in place a key employee equity plan that the Employee will participate
     in, such that, assuming (i) the value of the units (or other securities
     pursuant to such key employee equity plan) grows at a fifteen percent (15%)
     annual rate (compounded annually) from the date of their issuance, and (ii)
     the Employee is employed by the Company continuously for a five (5)-year
     period from the date of such issuance, the Employee would have equity value
     (computed as the difference between the value of the units (or other
     securities pursuant to the key employee equity plan) and the strike price)
     under such key employee equity plan equal to Five Hundred Thousand Dollars
     ($500,000) on the fifth anniversary date of such issuance. The Employee
     will vest in accordance with the provisions of such plan. In the event of
     an initial public offering ("IPO") of partnership units of a master limited
     partnership ("MLP") sponsored by the Company on or prior to August 31,
     2001, the Employee's rights under this Section 4(b) shall automatically
                                            ------------
     terminate and in lieu thereof Employee shall be granted options to acquire
     27,750 common units of the MLP with an
<PAGE>

     exercise price equal to the IPO price per common unit, all as may be
     subject to the provisions of such option agreement and/or plan of the MLP.

          (c)  Subject to Section 4(d) below, the Company agrees to pay the
                          ------------
     Employee certain performance bonuses based on targeted Operating Cash Flow
     (as defined below) for each fiscal year, beginning with the fiscal year
     beginning October 1, 2000. For each fiscal year during the term hereof the
     Company shall establish a targeted Operating Cash Flow for such fiscal
     year, and the Employee will receive a cash bonus to be paid within three
     months after the end of such fiscal year in the amount of: (i) $100,000, if
     the Company has Operating Cash Flow equal to or greater than targeted
     Operating Cash Flow for such fiscal year but less than 110% of such
     targeted Operating Cash Flow; or (ii) $125,000, if the Operating Cash Flow
     is equal to or greater than 110% of targeted Operating Cash Flow for such
     fiscal year but less than 120% of such targeted Operating Cash Flow for
     such year; or (iii) $150,000, if the Company has Operating Cash Flow of
     equal to or greater than 120% of targeted Operating Cash Flow for such
     fiscal year. For purposes of this Section 4(c), "Operating Cash Flow"
                                        ------------
     means net income in accordance with generally accepted accounting
     principals plus (i) income taxes, (ii) interest, (iii) depreciation, and
     (iv) amortization of intangibles, to the extent used in computing such net
     income, and minus capital expenditures made to maintain and service
     existing business expended by the Company during the fiscal year in
     question.  Notwithstanding the foregoing, in order to receive a bonus
     pursuant to this Section 4(c), the Employee must have been continuously
                      ------------
     employed by the Company from the date hereof until the end of the relevant
     fiscal year.

          (d)  In the event that the Company effects the IPO, effective at the
     beginning of the fiscal year of the Company next succeeding such IPO, in
     lieu of any payments under Section 4(c) above, the Company agrees to pay
                                ------------
     the Employee certain performance bonuses based on targeted Distributable
     Cash Flow ("DCF") (as defined below) for each fiscal year. For each fiscal
     year as to which there is to be a bonus under this Section 4(d), the
                                                        ------------
     Company shall establish a targeted DCF, and the Employee will receive a
     cash bonus to be paid within three months after the end of such fiscal year
     in the amount of: (i) $25,000, if the Company has DCF equal to or greater
     than 90% of targeted DCF for such fiscal year but less than 95% of targeted
     DCF during such fiscal year; (ii) $50,000, if the Company has DCF equal to
     or greater than 95% of targeted DCF for such fiscal year but less than
     targeted DCF during such fiscal year; (iii) $100,000, if the Company has
     DCF equal to or greater than targeted DCF for such fiscal year but less
     than 110% of targeted DCF for such fiscal year; (iv) $125,000, if the
     Company has DCF equal to or greater than 110% of targeted DCF but less than
     120% of targeted DCF during such fiscal year; or (v) $150,000, if the
     Company has DCF equal to or greater than 120% of targeted DCF during such
     fiscal year. Notwithstanding the previous sentence, in order to be eligible
     to receive any bonus under the previous sentence for the relevant fiscal
     year the Company must have earned and paid for such year distributions on
     each outstanding unit of the Company in an amount equal to four (4) times
     the greater of (A) the minimum quarterly distribution as defined in the
     Partnership Agreement of the MLP effecting the IPO, and (B) the highest
     quarterly distribution previously paid by the MLP with respect to all its
     units. For purposes of this Section 4(d), Distributable Cash Flow shall
                                 ------------
     have the same meaning as such term (or any comparable term, such as
     "Available Cash") is defined in the

                                       2
<PAGE>

     documents relating the MLP. Notwithstanding the foregoing, in order to
     receive a bonus pursuant to this Section 4(d), the Employee must have been
                                      ------------
     continuously employed by the Company from the date hereof until the end of
     the relevant fiscal year.


          (e)  It is anticipated by the parties hereto that in the event that
     the Company effects the IPO:

               (i)   The Company will receive Subordinated Units in the MLP that
          will have a yield equal to (but subordinated to) the yield on the
          publicly-traded common units;

               (ii)  At the expiration of the subordination period, the
          Subordinated Units will convert to common units of the MLP on a one-
          for-one basis and will receive distributions pro rata with all other
          common units;

               (iii) The subordination period will terminate based on the
          performance of the MLP in achieving certain earnings and distribution
          levels.

     In the event that the subordination period terminates with respect to all
     of the Subordinated Units, the Employee shall receive a cash bonus of Three
     Hundred Thousand Dollars ($300,000), with such bonus to be paid within
     sixty (60) days after the date of such termination; provided, however, that
     the Company may in its discretion pay all or part of such bonus prior to
     the termination of the subordination period with respect to all of the
     Subordinated Units; provided, further, that in the event the Company makes
     such early payments to the Employee and the subordination period is not
     subsequently terminated, the Employee shall not be required to repay such
     amounts to the Company.  Immediately upon a Change of Control (as defined
     below), within thirty (30) days of such Change of Control, the Company
     shall pay (A) the amount of the subordination bonus payable under this
     Section 4(e) to the extent unpaid, if such Change of Control results in the
     expiration of the subordination period, or (B) fifty percent (50%) of the
     amount of the subordination bonus to the extent unpaid, if such Change of
     Control does not result in the termination of the subordination bonus, with
     the balance of the subordination bonus to be paid pursuant to the previous
     sentence, or earlier in the event of a subsequent Change of Control that
     results in the termination of the subordination period.  For purposes of
     this Section 4(e), a "Change of Control" shall have the same meaning as
     that term is used in the Inergy Long Term Incentive Plan.

     Notwithstanding the foregoing, in order to receive a bonus with respect to
     the termination of the subordination period for all Subordinated Units, the
     Employee must have been continuously employed by the Company from the date
     hereof until the date of such termination.  In the event the Employee's
     employment is terminated without Cause, as defined herein, prior to the
     full payment of the subordination bonus and a portion of the subordinated
     units have previously been converted, the Company shall pay to Employee an
     amount equal to Employee's total subordination bonus times a fraction equal
     to the number of all subordinated units of the MLP which have converted to
     common units divided by the total number of subordinated units issued by
     the MLP.

                                       3

          5.   Duties.  The Employee agrees that so long as he is employed
               ------
under this Agreement he will (i) to the satisfaction of the Company devote his
best efforts and his entire business time to further properly the interests of
the Company, (ii) at all times be subject to the Company's direction and control
with respect to his activities on behalf of the Company, (iii) comply with all
rules, orders and regulations of the Company, (iv) truthfully and accurately
maintain and preserve such records and make all reports as the Company may

of which he may from time to time have custody and deliver the same to the
Company whenever and however directed to do so.

          6.   Disclosure and Assignment of Inventions.
               ---------------------------------------

          (a)  The Employee agrees that any Inventions (as hereinafter defined)
     that he, alone or with others, may conceive, develop, make or perfect, in
     whole or in part, during his employment by the Company which relate or
     pertain in any way to the existing or reasonably anticipated scope of the
     Company's or any subsidiary, parent or affiliate of the Company's business,
     or that he, alone or with others, may conceive, make or perfect in whole or
     in part, in the performance of the duties of his employment by the Company,
     shall be promptly and fully disclosed in writing immediately by the
     Employee to the Company (but to no other person or persons prior to
     procuring patents therefor). All of the right, title and interest in and to
     any Invention shall be and hereby is assigned exclusively to the Company or
     its nominee regardless of whether or not the conception, development,
     making or perfection of such Inventions involved the use of the Company's
     time, facilities or materials and regardless of where such Inventions may
     be conceived, made or perfected and shall become the sole property of the
     Company or its nominee. For purposes hereof, the term "Inventions" shall
     mean inventions, discoveries, ideas, concepts, systems, works, trade
     secrets, know-how, intellectual property, products, processes or
     improvements or modifications of current products, processes or designs, or
     methods of manufacture, distribution, management or otherwise (whether or
     not covered by or able to be covered by a patent or copyright).

          (b)  The Employee agrees to execute and deliver all documents and do
     all acts which the Company shall deem necessary or desirable to secure to
     the Company or its nominee the entire right, title and interest in and to
     said Inventions, including, without limitation, applications for any United
     States and/or Foreign Letters Patent or Certificates of Copyright
     Registration in the name of or for the benefit of the Company or, in the
     discretion of the Company, in the Employee's name, which patents and
     copyrights shall then be assigned by the Employee to the Company. Any
     document described above prepared and filed pursuant to this subsection
     shall be so prepared and filed at the Company's expense. The Employee
     hereby irrevocably appoints the President of the Company as his attorney-in
     -fact with authority to execute for him and on his behalf any and all
     assignments, patent or copyright applications, or other instruments and
     documents required to be executed by the Employee pursuant to this
     subsection, if the Employee is unwilling or unable to execute same.

          (c)  The Company shall have no obligation to use, attempt to protect
     by application for Letters Patent or Certificates of Copyright Registration
     or promote any of

                                       4
<PAGE>

     said Inventions; provided, however, that the Company, in its sole
     discretion, may reward the Employee for any especially meritorious
     contributions in any manner it deems appropriate or may provide the
     Employee with full or partial releases as to any subject matter contributed
     by the Employee in which the Company is not interested.

          7.  Covenant Not to Disclose Confidential Information.  The Employee
              -------------------------------------------------
acknowledges that during the course of his employment with the Company he has or
will have access to and knowledge of certain information and data which the
Company or any subsidiary, parent or affiliate of the Company considers
confidential and that the release of such information or data to unauthorized
persons would be extremely detrimental to the Company.  As a consequence, the
Employee hereby agrees and acknowledges that he owes a duty to the Company not
to disclose, and agrees that, during or after the term of his employment,
without the prior written consent of the Company, he will not communicate,
publish or disclose, to any person anywhere or use any Confidential Information
(as hereinafter defined) for any purpose other than carrying out his duties as
contemplated by this Agreement.  The Employee will use his best efforts at all
times to hold in confidence and to safeguard any Confidential Information from
falling into the hands of any unauthorized person and, in particular, will not
permit any Confidential Information to be read, duplicated or copied.  The
Employee will return to the Company all Confidential Information in the
Employee's possession or under the Employee's control when the duties of the
Employee no longer require the Employee's possession thereof, or whenever the
Company shall so request, and in any event will promptly return all such
Confidential Information if the Employee's relationship with the Company is
terminated for any or no reason and will not retain any copies thereof.  For
purposes hereof the term "Confidential Information" shall mean any information
or data used by or belonging or relating to the Company or any subsidiary,
parent or affiliate of the Company that is not known generally to the industry
in which the Company or any subsidiary, parent or affiliate of the Company is or
may be engaged, including without limitation, any and all trade secrets,
proprietary data and information relating to the Company's or any subsidiary,
parent or affiliate of the Company's past, present or future business and
products, price lists, customer lists, processes, procedures or standards, know-
how, manuals, business strategies, records, drawings, specifications, designs,
financial information, whether or not reduced to writing, or information or data
which the Company or any subsidiary, parent or affiliate of the Company advises
the Employee should be treated as confidential information.

          8.   Covenant Not to Compete.  The Employee acknowledges that during
               -----------------------
his employment with the Company he, at the expense of the Company, has been and
will be specially trained in the business of the Company, has established and
will continue to establish favorable relations with the customers, clients,
accounts and lenders of the Company or any subsidiary, parent or affiliate of
the Company and will have access to Inventions, trade secrets and Confidential
Information of the Company or any subsidiary, parent or affiliate of the
Company. Therefore, in consideration of such training and relations, his
employment with the Company, and to further protect the Inventions, trade
secrets and Confidential Information of the Company or any subsidiary, parent or
affiliate of the Company, the Employee agrees that for a period commencing on
the date hereof and ending on the later of (i) one year from and after the date
of the voluntary or involuntary termination of the Employee's employment by the
Company for any reason or no reason (including, without limitation, a
termination due to the fulfillment of the term of this Agreement pursuant to
Section 11(a) hereof), provided, however, that in the

                                       5
<PAGE>

event that the date of the voluntary or involuntary termination of the
Employee's employment by the Company for any or no reason occurs on or after the
second anniversary of the date hereof, the Company shall have the option to
extend such one year period of time by an additional one year period by electing
to continue to pay the Employee's salary at the time of termination, payable bi-
monthly in arrears, for the period of one year following the date of the
voluntary or involuntary termination of the Employee's employment by the Company
for any or no reason, (ii) the third anniversary of the date hereof, and (iii)
in the event the Company makes any payments under Section 11(e) hereof, the
later of (x) the fifth anniversary of the date hereof, and (y) one year from and
after the date of the termination of the Employee's employment by the Company,
he will not, directly or indirectly, without the express written consent of the
Company, except when and as requested to do in and about the performing of his
duties under this Agreement:

          (a)  own, manage, operate, control or participate in the ownership,
     management, operation or control of, or have any interest, financial or
     otherwise, in or act as an officer, director, partner, member, principal,
     employee, agent, representative, consultant or independent contractor of,
     or in any way assist any individual or entity in the conduct of any
     business that is engaged or may become engaged in any business competitive
     to any business now or at any time during the period hereof engaged in by
     the Company or any subsidiary, parent or affiliate of the Company,
     including, but not limited to, any business that trades, markets or
     distributes propane gas (at retail, wholesale or otherwise) or sells,
     services and installs parts, appliances or supplies related thereto;

          (b)  divert or attempt to divert clients or customers (whether or not
     such persons have done business with the Company or any subsidiary, parent
     or affiliate of the Company once or more than once) or accounts of the
     Company or any subsidiary, parent or affiliate of the Company; or

          (c)  entice or induce or in any manner influence any person who is or
     shall be in the employ or service of the Company or any subsidiary, parent
     or affiliate of the Company to leave such employ or service for the purpose
     of engaging in a business which may be in competition with any business now
     or at any time during the period hereof engaged in by the Company or any
     subsidiary, parent or affiliate of the Company.

Notwithstanding the foregoing provisions, the Employee may own not more than
five percent (5%) of the outstanding equity securities in any corporation or
entity (including, but not limited to, units in a master limited partnership)
that is listed upon a national stock exchange or actively traded in the over-
the-counter market.  Notwithstanding the foregoing provisions, the Employee
shall not, directly or indirectly, without the express written consent of the
Company, except when and as requested to do in and about the performing of his
duties under this Agreement, engage in any actions under subsections (a), (b) or
(c) above, at any time the Company is making payments to the Employee pursuant
to this Agreement.

          9.   Specific Performance.  Recognizing that irreparable damage will
               --------------------
result to the Company in the event of the breach or threatened breach of any of
the foregoing covenants and assurances by the Employee contained in Sections 6,
                                                                    -----------
7 or 8 hereof, and that the Company's
------

                                       6
<PAGE>

remedies at law for any such breach or threatened breach will be inadequate, the
Company and its successors and assigns, in addition to such other remedies which
may be available to them, shall be entitled to an injunction, including a
mandatory injunction, to be issued by any court of competent jurisdiction
ordering compliance with this Agreement or enjoining and restraining the
Employee, and each and every person, firm or company acting in concert or
participation with him, from the continuation of such breach and, in addition
thereto, he shall pay to the Company all ascertainable damages, including costs
and reasonable attorneys' fees sustained by the Company by reason of the breach
or threatened breach of said covenants and assurances. The obligations of the
Employee and the rights of the Company, its successors and assigns under
Sections 6, 7, 8, 9, 10, 12, 16 and 18 of this Agreement shall survive the
--------------------------------------
termination of this Agreement. The covenants and obligations of the Employee set
forth in Sections 6, 7 and 8 hereof are in addition to and not in lieu of or
         -------------------
exclusive of any other obligations and duties of the Employee to the Company,
whether express or implied in fact or in law.

          10.  Potential Unenforceability of Any Provision.  If a final judicial
               -------------------------------------------
determination is made that any provision of this Agreement is an unenforceable
restriction against the Employee, the provisions hereof shall be rendered void
only to the extent that such judicial determination finds such provisions
unenforceable, and such unenforceable provisions shall automatically be
reconstituted and become a part of this Agreement, effective as of the date
first written above, to the maximum extent in favor of the Company that is
lawfully enforceable.  A judicial determination that any provision of this
Agreement is unenforceable shall in no instance render the entire Agreement
unenforceable, but rather the Agreement will continue in full force and effect
absent any unenforceable provision to the maximum extent permitted by law.

          11.  Term and Termination.
               --------------------

          (a)  Subject to Sections 11(b) and 11(c) below, the term of the
                          --------------     -----
     Employee's employment under this Agreement shall be five (5) years from the

          (b)  Notwithstanding Section 11(a) above, this Agreement shall
                               -------------
     terminate immediately upon the death, disability or adjudication of legal
     incompetence of the Employee, or upon the Company's ceasing to carry on its
     business or becoming bankrupt.  For purposes of this Agreement, the
     Employee shall be deemed to be disabled when the Employee has become
     unable, by reason of physical or mental disability, to satisfactorily
     perform his essential job duties and there is no reasonable accommodation
     that can be provided to enable him to be a qualified individual with a
     disability under applicable law.  Such matters shall be determined by, or
     to the reasonable satisfaction of, the Company.

          (c)  Notwithstanding Section 11(a) above, the Company may terminate
                               -------------
     the Employee's employment at any time for Cause or without Cause. "Cause"
     means (i) the Employee has failed to perform the duties assigned to him and
     such failure has continued for thirty (30) days following delivery by the
     Company of written notice to the Employee of such failure, (ii) the
     Employee has been convicted of a felony or misdemeanor involving moral
     turpitude, (iii) the Employee has engaged in acts or omissions against the
     Company constituting dishonesty, breach of fiduciary obligation, or
     intentional wrongdoing or misfeasance, (iv) the Employee has acted
     intentionally or in bad faith in a

                                       7
<PAGE>

     manner that results in a material detriment to the assets, business or
     prospects of the Company, or (v) the Employee has breached any obligation
     under this Agreement.

          (d)  In the event (x) the Company elects to terminate the Employee's
     employment with the Company for Cause or as a result of the death,
     disability, adjudication of legal incompetence of the Employee or the
     Company's ceasing to carry on its business or becoming bankrupt, or (y) the
     Employee terminates his employment with the Company for any reason or no
