(ii)           Annual Bonus. In addition to the Base Salary, the Executive shall be eligible to earn, for each fiscal year of the Employer ending during the Employment Period, an annual cash bonus of up to one hundred percent (100%) of the Base Salary based upon performance parameters as approved by the Board based upon the Employer’s Short Term Incentive Plan (the “Annual Bonus”).

The failure by the Executive or the Employer to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Good Reason or Cause shall not waive any right of the Executive or the Employer, respectively, hereunder or preclude the Executive or the Employer, respectively, from asserting such fact or circumstance in enforcing the Executive’s or the Employer’s rights hereunder.

5.             Obligations of the Employer upon Termination.

(a)           Good Reason; Other Than for Cause, Death or Disability. If, during the Employment Period, the Employer shall terminate the Executive’s employment without Cause (other than as a consequence of death or Disability, which shall have the effects set

3

forth in Section 5(c) below), or the Executive shall terminate employment for Good Reason:

(i)            The Executive shall be paid, in a single lump sum payment within thirty (30) days after the Date of Termination, the aggregate amount of (A) the Executive’s earned but unpaid Base Salary and accrued but unpaid vacation pay, if any, through the Date of Termination, any Annual Bonus required to be paid to the Executive pursuant to Section 3(b)(ii) hereof for any fiscal year that ends on or before the Date of Termination and payment with respect to Phantom Options required to be paid to the Executive pursuant to Section 3(b)(iii) hereof for any fiscal year that ends on or before the Date of Termination to the extent not previously paid (the “Accrued Obligations”), plus (B) the present value (using the prime rate of the Employer’s banker at such time) of all employee benefits referred to in Section 3(b)(iv) hereof, other than group medical, drug and dental benefits, as referred to in Section 5(a)(ii) hereof (which would have been available to the Executive for a period of twenty-four (24) months from the Date of Termination), plus (C) two (2) times the sum of (X) the Executive’s Base Salary as in effect immediately prior to the Date of Termination and (Y) the average of his Annual Bonuses for the two (2) years immediately preceding the Date of Termination;

(ii)           For a period of two (2) years following the Date of Termination, the Executive and/or the Executive’s eligible dependents shall continue to be provided with medical, prescription and dental benefits at least equal to those which would have been provided to them in accordance with the plans, programs, practices and policies if the Executive’s employment had not been terminated.  Notwithstanding the foregoing, the Executive shall cease to receive such medical, prescription and dental benefits on the date the Executive is eligible to receive such benefits under another employer-provided group plan. Such health benefits shall be provided to the Executive in a manner that neither the coverage nor the benefits are includible in the Executive’s taxable gross income.  If the Employer is unable to provide such coverage or benefits to the Executive on that basis, then the Employer shall pay the Executive such additional amounts as necessary to make the Executive “whole” on a net after-tax basis for the receipt of such coverage or benefits;

(iii)          The Executive’s Phantom Options shall vest as of the Date of Termination and shall be payable as set forth in Appendix B hereto; and

(iv)          To the extent not theretofore paid or provided, the Employer shall timely pay or provide to the Executive any accrued benefits and other amounts or benefits required to be paid or provided or which the Executive is eligible to receive prior to the Date of Termination under any plan, program, policy or practice or contract or agreement of the Employer and its affiliates according to their terms (such other amounts and benefits shall be hereinafter referred to as the “Other Benefits”).

(b)           Cause; Other than for Good Reason. If the Executive’s employment shall be terminated by the Employer for Cause or by the Executive other than for Good Reason during the Employment Period, the Employer shall pay to the Executive the Accrued Obligations in cash within thirty (30) days after the Date of Termination and shall provide any Other Benefits which have accrued during the Employment Period.

(c)           Death or Disability. If the Executive’s employment is terminated by reason of the Executive’s death or Disability during the Employment Period:

(i)            The Accrued Obligations shall be paid to the Executive’s estate or beneficiaries or to the Executive, as applicable, in cash within thirty (30) days of the Date of Termination;

(ii)           At the time when annual bonuses are paid to other peer executives of the Employer for the fiscal year in which the Date of Termination occurs, the Executive’s estate or beneficiaries or the Executive, as applicable, shall be paid an amount equal to the product of (A) the amount of the Annual Bonus to which the Executive would have been entitled, if the Executive’s employment had not been terminated, and (B) a fraction, the numerator of which shall be the number of days in such fiscal year through the Date of Termination and the denominator of which shall be 365, to the extent not theretofore paid;

(iii)          The Executive’s Phantom Options shall vest as of the Date of Termination and shall be payable as set forth in Appendix B hereto; and

(iv)          The Other Benefits shall be paid or provided to the Executive’s estate or beneficiaries or to the Executive, as applicable, on a timely basis; and

(v)           Through the remainder of the Employment Period, or such longer period as may be provided by the terms of the appropriate plan, program, practice or policy, the Executive and/or the Executive’s eligible dependents shall continue to be provided with medical, prescription and dental benefits as if the Executive’s employment had not been terminated.  Such health benefits shall be provided to the eligible dependents in a manner that neither the coverage nor the benefits are includible in the eligible dependent’s taxable gross income.  If the Employer is unable to provide such coverage or benefits to the eligible dependent on that basis, then the Employer shall pay the eligible dependent such additional amounts as necessary to make the eligible dependent “whole” on a net after-tax basis for the receipt of such coverage or benefits;

6.             Non-exclusivity of Rights. Nothing in this Agreement shall prevent or limit the Executive’s continuing or future participation in any plan, program, policy or practice provided by the Employer (other than policies relating to severance payments or obligations on termination of employment for any reason) and for which the Executive may qualify, nor shall anything herein limit or otherwise affect such rights as the Executive may have under any contract or agreement with the Employer. Amounts which are vested benefits or which the Executive is otherwise entitled to receive under any plan, policy, practice or program of or any

5

contract or agreement with the Employer at or subsequent to the Date of Termination shall be payable in accordance with such plan, policy, practice or program or contract or agreement except as explicitly modified by this Agreement.

7.             Full Settlement. The Employer’s obligation to make the payments provided for in this Agreement and otherwise to perform its obligations hereunder shall not be affected by any set-off, counterclaim, recoupment, defense or other claim, right or action which the Employer may have against the Executive or others. In no event shall the Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement, and, except as provided in Section 5(a)(ii) hereof, such amounts shall not be reduced whether or not the Executive obtains other employment.

8.             Executive’s Covenants.

(a)           The Executive shall hold in a fiduciary capacity for the benefit of the Employer all secret or confidential information, knowledge or data relating to the Employer, and its respective businesses, which shall have been obtained by the Executive during the Executive’s employment by the Employer and which shall not be or become public knowledge (other than by acts by the Executive or representatives of the Executive in violation of this Agreement). After termination of the Executive’s employment with the Employer, the Executive shall not, directly or indirectly, without the prior written consent of the Employer or as may otherwise be required by law or legal process, use for his own benefit such information, knowledge or data, or communicate or divulge any such information, knowledge or data to anyone other than the Employer and those designated by it; provided, that if the Executive receives actual notice that the Executive is or may be required by law or legal process to communicate or divulge any such information, knowledge or data, the Executive shall promptly so notify the Employer.

(b)           While employed by the Employer and for a period of two (2) years following the Date of Termination, regardless of the reason for the termination, the Executive shall not, without the prior consent of the Employer (which consent shall not be unreasonably withheld), directly or indirectly (i) solicit, induce, or encourage any employee of the Employer who is employed at any time within six (6) months of the time of termination to terminate his or her employment with the Employer or (ii) hire any such employee within six (6) months after that employee’s termination of employment with the Employer.

(c)           While employed by the Employer and for a period of two (2) years following the Date of Termination, regardless of the reason for the termination, the Executive shall not, without the prior consent of the Employer, be employed by, provide consultative service to (with or without pay), own, manage, operate, join, control, participate in, or be connected with (as a stockholder, partner, or otherwise), any business, individual, partner, firm, corporation, or other entity that is a Competitor of the Employer; provided, however, that the “beneficial ownership” by the Executive, either individually or as a member of a “group,” as such terms are used in Rule 13d of the General Rules and Regulations under the Securities Exchange Act of 1934, as amended,

6

of not more than two percent (2%) of the voting stock of any publicly held corporation shall not be a violation of this Agreement.

(d)           In no event shall an asserted violation of the provisions of this Section 8 constitute a basis for deferring or withholding any amounts otherwise payable to the Executive under this Agreement. However, in recognition of the facts that irreparable injury will result to the Employer in the event of a breach by the Executive of his obligations under Sections 8(a), 8(b) and 8(c) above, that monetary damages for such breach would not be readily calculable, and that the Employer would not have an adequate remedy at law therefor, the Executive acknowledges, consents and agrees that in the event of such breach, or the threat thereof, the Employer shall be entitled, in addition to any other legal remedies and damages available, to specific performance thereof and to temporary and permanent injunctive relief (without the necessity of posting a bond) to restrain the violation or threatened violation of such obligations by the Executive.

(e)           Upon the termination of Executive’s employment with the Employer for any reason, Executive shall immediately return and deliver to the Employer any and all papers, books, records, documents, memoranda and manuals, e-mail, electronic or magnetic  recordings or data, including all copies thereof, belonging to the Employer or relating to its business, in Executive’s possession, whether prepared by Executive or others. If at any time after the Employment Period, Executive determines that he has any secret or confidential information in his possession or control, Executive shall immediately return to the Employer all such information, including all copies and portions thereof.

9.             Successors.

(a)           This Agreement is personal to the Executive and without the prior written consent of the Employer shall not be assignable by the Executive otherwise than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by the Executive’s legal representatives.

(b)           This Agreement shall inure to the benefit of and be binding upon the Employer and its successors and assigns.

(c)           The Employer shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Employer to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Employer would be required to perform it if no such succession had taken place. As used in this Agreement, “Employer” shall mean the Employer as defined in this Agreement and any successor to its business and/or assets as aforesaid which assumes and agrees to perform this Agreement by operation of law or otherwise.

10.           Indemnification and Directors’ and Officers’ Insurance.

(a)           During the Employment Period and thereafter, the Employer shall indemnify the Executive to the fullest extent permitted under law from and against any

7

expenses (including but not limited to attorneys’ fees, expenses of investigation and preparation and fees and disbursements of the Executive’s accountants or other experts), judgments, fines, penalties and amounts paid in settlement actually and reasonably incurred by the Executive in connection with any proceeding in which the Executive was or is made party or was or is involved (for example, as a witness) by reason of the fact the Executive was or is employed by the Employer. Such indemnification shall continue as to the Executive during the Employment Period and for at least six (6) years from the Date of Termination with respect to acts or omissions which occurred prior to his cessation of employment with the Employer and shall inure to the benefit of the Executive’s heirs, executors and administrators. The Employer shall advance to the Executive all costs and expenses incurred by him in connection with any proceeding covered by this provision within twenty (20) calendar days after receipt by the Employer of a written request for such advance. Such request shall include an undertaking by the Executive to repay the amount of such advance if it shall ultimately be determined that he is not entitled to be indemnified against such costs and expenses.

(b)           The Employer agrees to maintain directors’ and officers’ liability insurance policies covering the Executive which shall provide him with coverage that is at least as favorable to the Executive as the coverage that Provident provides to its directors and officers from time to time. Such insurance coverage shall continue as to the Executive even if he has ceased to be a director, member, employee or agent of the Employer with respect to acts or omissions which occurred prior to his cessation of employment with the Employer. Insurance contemplated under this Section 10(b) shall inure to the benefit of the Executive’s heirs, executors and administrators.

11.           Miscellaneous.

(a)           This Agreement shall be governed by and construed in accordance with the laws of the State of California, without reference to principles of conflict of laws. The captions of this Agreement are not part of the provisions hereof and shall have no force or effect. This Agreement may not be amended or modified otherwise than by a written agreement executed by the parties hereto or their respective successors and legal representatives.

(b)           All notices and other communications hereunder shall be in writing and shall be given by hand delivery to the other party or by registered or certified mail, return receipt requested, postage prepaid, addressed as follows:

8

If to the Executive:   at the Executive’s most recent address on the records of the Employer; and

If to the Employer:

with a copy to:

or to such other address as either party shall have furnished to the other in writing in accordance herewith. Notice and communications shall be effective when actually received by the addressee.

(c)           The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement.

(d)           The Employer may withhold from any amounts payable under this Agreement such federal, state, local or foreign taxes as shall be required to be withheld pursuant to any applicable law or regulation.

(e)           The Executive’s or the Employer’s failure to insist upon strict compliance with any provision of this Agreement or the failure to assert any right the Executive or the Employer may have hereunder, including, without limitation, the right of the Executive to terminate employment for Good Reason pursuant to Section 4(c) hereof, shall not be deemed to be a waiver of such provision or right or any other provision or right of this Agreement.

9

(f)            This Agreement, including the Appendices hereto, constitutes the entire agreement of the parties with respect to the subject matter hereof and is intended to supersede and replace the Prior Agreement and any other prior employment or severance agreements or arrangements between the Executive, on the one hand, and BECLP GP, the Partnership, the MLP GP and Manageco, on the other.

(g)           The Executive represents that he has not, either individually or as a representative or member of a class, filed or caused to be filed any complaints, charges or lawsuits against the Partnership or the Employer with any governmental agency, court, arbitrator or mediator with respect to his employment by the Partnership or the Employer and releases any such claims he may have against the Partnership or the Employer as of the date of this Agreement.

(h)           Notwithstanding anything in this Agreement to the contrary, it is intended that all items of compensation provided for under this Agreement, including Attachment B, shall be paid to the Executive within the time period required to qualify as a “short-term deferral” that is exempt from the additional tax under Section 409A of the Internal Revenue Code (“Code”); provided, however, if the Executive is a “specified employee,” as defined in Code Section 409A with respect to the Employer or an affiliate, payments pursuant to this Agreement shall be paid on the date which is six months after the date of the Executive’s “separation from service,” as defined in Code Section 409A and the regulations thereunder, or, if earlier, the date of the Executive’s death in a lump sum.  In the event that any payment hereunder would subject the Executive to the additional tax provided under Section 409A, the parties shall take all reasonable actions, including amendments hereto, for such payment either to comply with the requirements of Section 409A or to be exempt therefrom.  If the Executive, nonetheless, becomes subject to the additional tax under Section 409A with respect to any payment hereunder, the Employer shall pay the Executive an additional lump sum cash amount such that after such additional lump sum the Executive is in the same net after-tax position he would have been in had no payments under this Agreement subjected him to the additional tax under Section 409A.

(i)            During the Employment Period beginning on and following the IPO Date, the parties agree that the Executive shall serve as the Co-Chief Executive Officer of BECLP GP, the MLP GP and Manageco and also as a member of the Boards of Directors of each of such entities.  The parties intend for the provisions of this Agreement to be construed as necessary to effectuate this intent, including when appropriate as if it were a separate agreement with each Employer.  However, nothing herein shall operate or be construed as providing the Executive with a duplication of compensation from the Employers.  The Boards of Directors of BECLP GP, the MLP GP and Manageco shall use their best efforts to resolve any ambiguities or conflicts as to their respective obligations to the Executive under this Agreement and the cost of the Executive’s compensation (other than the Phantom Options) and benefits shall be shared by them on the basis of his estimated time devoted to the business of each or on such other basis as the Employers may mutually agree.

10

(j)            This Agreement may be executed simultaneously in one or more counterparts, each of which shall be deemed an original but which together shall constitute one and the same instrument.

A.            Pre-IPO Date Grants.

1.             Pursuant to Section 3(b)(iii) of the Employment Agreement by and between Pro GP Corp. (the “BECLP GP”), BreitBurn Management Company, LLC (the “Manageco”), BreitBurn GP, LLC (the “MLP GP”) and Randall Breitenbach (the “Executive”), dated as of October 10, 2006 (the “Agreement”), the Partnership shall grant Phantom Options to the Executive on the following terms and conditions. All capitalized terms not defined herein shall have the meanings set forth in the Agreement.

2.             Effective as of the first (1st) day of each fiscal year of the Partnership (currently the calendar year) after the date of the Agreement and during the Employment Period (the “Grant Date”), BECLP GP shall cause the Partnership to grant a Phantom Option to the Executive with respect to one Phantom Unit, as defined below.

3.             A “Phantom Unit” shall mean a hypothetical, nonexistent unit of Partnership Interests (as defined in the Partnership Agreement) equal to the lesser of (a) a Percentage Interest (as defined in the Partnership Agreement) equal to one and one-half percent (1.5%) of the total outstanding Partnership Interests as of the Grant Date or (b) a Percentage Interest that has a value equal to fifteen million dollars ($15,000,000) as of the Grant Date determined on the basis of the Partnership Valuation (defined in Section 6.6.1 of the Partnership Agreement) for the year prior to the Grant Date for each grant.

4.             Each Phantom Option shall represent the right to a receive a payment (the “Phantom Option Payment”) equal to the difference between (a) sum of (i) the Value of the Phantom Unit (as defined below) as of the Determination Date (as defined below) and (ii) the amount of distributions of cash or property (valued by the Board at fair market value and in good faith) made by the Partnership to its partners during the period (the “Option Period”) beginning on the Grant Date and ending on the Determination Date that the Executive would have been entitled to receive during the Option Period if he had actually owned the Partnership Interests represented by the Phantom Unit during the entire Option Period, and (b) one hundred and eight percent (108%) of the Value of the Phantom Unit as of the Grant Date. In no event shall the amount of a Phantom Option Payment be a negative number or in any way affect the amount of the Executive’s compensation under the Agreement or any subsequent Phantom Option granted hereunder.

5.             The “Value of the Phantom Unit” as of any date shall be equal to the value, determined on the basis of the Partnership Valuation as of that date, of the Partnership Interests underlying the Phantom Unit as set forth in paragraph 3 above.

6.             The “Determination Date” with respect to a Phantom Option shall be the last day of the Partnership’s fiscal year (currently, December 31), except in the event of the termination of the Executive’s employment with the Employer prior to the end of the Partnership’s fiscal year, in which case the Determination Date shall be the Date of Termination.

B-1

7.             The Phantom Option Payment shall be made in cash, unless the Board of Directors of Pro GP Corp. determines that it should be paid in freely tradable publicly held trust units of Provident. The Phantom Option Payment shall be made to the Executive, or to his beneficiaries, heirs or estate in the event of his death, as soon as practicable, but in no event more than sixty (60) days after the Determination Date.

8.             Subject to Section 9 below, the Executive shall acquire a vested and non-forfeitable interest in the Phantom Option as of the last day of the Partnership’s fiscal year if the Executive is employed by the Employer on such day.

9.             In the event of the termination of the Executive’s employment by the Employer without Cause, by the Executive for Good Reason, or by reason of the Executive’s death or Disability, (a) the Executive shall acquire a vested and non-forfeitable interest in the Phantom Option as of the Date of Termination, (b) the Option Period shall end on the Date of Termination and (c) the Phantom Option Payment shall be made as soon as practicable, but in no event more than sixty (60) days after the Date of Termination. In the event of the termination of the Executive’s employment by the Employer for Cause or by the Executive without Good Reason, the Executive shall forfeit the Phantom Option as of the Date of Termination and the Employer shall have no further obligations to the Executive with respect to such Phantom Option.

10.           Upon the Employer’s payment of the Phantom Option Payment with respect to a Phantom Option, such Phantom Option shall automatically terminate and be of no further force or effect.

11.           The Employer shall withhold all applicable income taxes and employment taxes from the Phantom Option Payment as may be required by law.

12.           The Phantom Option, or any interest in it, shall not be assignable by the Executive and shall not be subject to attachment, lien, levy or other creditors’ rights under state or Federal law. The Phantom Option Payments shall be payable by the Employer from its general assets or pursuant to such other means as the Employer deems appropriate, and the Executive shall not be entitled to look to any source for payment of such benefits other than the general assets of the Employer.

13.           Effective on the IPO Date, the Executive’s outstanding Phantom Option for the 2006 fiscal year of the Employer shall be converted automatically into the following three separate Phantom Option awards:  (1) a Phantom Unit representing a 1.5% Partnership Interest with respect to the operations for the 2006 fiscal year attributable to the properties of the Partnership not transferred to BreitBurn Energy Partners L.P. (the “Retained Business”) (the “First Option”), (2) a Phantom Unit representing a 1.5% Partnership Interest with respect to the operations attributable to the properties of the Partnership transferred to BreitBurn Energy Partners L.P. (the “Transferred Business”) (the “Second Option”) for the 2006 fiscal period ending on the IPO Date, and (3) a Phantom Unit representing a 1.5% Partnership Interest in the MLP for the period beginning on the IPO Date and ending on December 31, 2006.  The value of the First Option shall be determined as set forth in paragraph 4 above on the basis of the Partnership Valuation for 2006 for the Retained Business; the value of the Second Option shall be determined as set forth in paragraph 4 above on the basis of the Partnership Valuation for the

B-2

Transferred Business for the period beginning January 1, 2006 and ending on the IPO Date, based on the January 1, 2006 Partnership Valuation for the Transferred Business and the IPO offering price for a MLP unit; and the value of the Third Option shall be determined as set forth in paragraph 4 above based on the value of a MLP unit for the period beginning on the IPO Date and ending December 31, 2006.

Except for these changes, the Phantom Options shall continue with the same terms as before the IPO except that the Phantom Options may be further modified as necessary or helpful to effectuate the intent of the parties to reflect the conversion of the Phantom Option into three separate Phantom Options as described above on the IPO Date.

B.            Post-IPO Date Grants.

1.             Pursuant to Section 3(b)(iii) of the Agreement, the Employer shall grant or cause the grant of Phantom Options (as defined below) to the Executive on the following terms and conditions.

2.             Effective as of the first (1st) day of each fiscal year of the Employer (currently the calendar year) after the IPO Date and during the Employment Period (the “Grant Date”), (i) Pro GP Corp. shall grant or cause the grant to the Executive of one Partnership Phantom Unit and (ii) Manageco shall grant or cause the grant to the Executive of one MLP Phantom Unit, as such terms are defined below.

3.             (i) A “Partnership Phantom Unit” shall mean a hypothetical, nonexistent unit of Partnership Interests (as defined in the Partnership Agreement) equal to the lesser of (a) a Percentage Interest (as defined in the Partnership Agreement) equal to one and one-half percent (1.5%) of the total outstanding Partnership Interests as of the Grant Date or (b) a Percentage Interest that has a value equal to the Applicable Dollar Amount (as defined below) as of the Grant Date, determined on the basis of the Partnership Valuation (defined in Section 6.6.1 of the Partnership Agreement) for the Grant Date for each grant;

(ii)           A “MLP Phantom Unit” shall mean a hypothetical, nonexistent unit of MLP Partnership Interests (as defined in the MLP Partnership Agreement) equal to the lesser of (a) a Percentage Interest (as defined in the MLP Partnership Agreement) equal to one and one-half percent (1.5%) of the total outstanding MLP Partnership Interests as of the Grant Date or (b) a Percentage Interest that has a value equal to the Applicable Dollar Amount as of the Grant Date, determined on the basis of the value of the MLP Units on the Grant Date for each grant.

(iii)          If the sum of the Partnership Valuation and the MLP value on the Grant Date (the “Combined Value”) exceeds $1 billion, then the Applicable Dollar Amounts with respect to a Partnership Phantom Unit and a MLP Phantom Unit shall be determined as follows: (i) the Partnership Applicable Dollar Amount shall be equal to the product of $15 million and the Partnership fraction, where the numerator is the Partnership Valuation and the denominator is the Combined Value, and (ii) the MLP Applicable Dollar Amount shall be equal to the product of $15 million and the MLP fraction, where the numerator is the MLP value and the denominator is the Combined Value.  If the Combined Value on the Grant Date does not exceed $1 billion, then the Applicable Dollar Amount for the Partnership and the MLP shall be equal to the value of the

B-3

one and one-half percent (1.5%) Percentage Interest applicable for the Partnership and the MLP, respectively, on such Grant Date.

As used herein, the Partnership Agreement and the MLP Partnership Agreement shall mean the partnership agreement for the Partnership and the MLP, respectively.  A “Phantom Unit” shall mean either a Partnership Phantom Unit, a MLP Phantom Unit or both, as the context requires.

4.             Subject to paragraph 6 below, each Phantom Unit shall represent the right to a receive a payment (the “Phantom Unit Payment”) equal to the difference between (a) the sum of (i) the Value of the Phantom Unit (as defined below) as of the Determination Date (as defined below) and (ii) the amount of distributions of cash or property (with respect to a property distribution, valued by the Board of Directors of the general partner of the Partnership or the MLP GP at fair market value and in good faith) made by the Partnership or the MLP, as the case may be, to its partners during the period (the “Option Period”) beginning on the Grant Date and ending on the Determination Date that the Executive would have been entitled to receive during the Option Period if he had actually owned the Partnership Interests represented by the Phantom Unit during the entire Option Period, and (b) one hundred and eight percent (108%) of the Value of the Phantom Unit as of the Grant Date. Except as provided in paragraph 6 below with respect to the MLP carry over amount, in no event shall the amount of a Phantom Unit Payment be a negative number or in any way affect the amount of the Executive’s compensation under the Agreement or any subsequent Phantom Option granted hereunder.

5.             The “Value of the Phantom Unit” as of any date (i) with respect to a Partnership Phantom Unit, shall be equal to the value, determined on the basis of the Partnership Valuation as of that date (but using the market value of any MLP units owned by the Partnership), of the Partnership Interests underlying the Phantom Unit as set forth in paragraph 3 above, and (ii) with respect to a MLP Phantom Unit, shall be equal to the value of the Partnership Interests underlying the Phantom Unit as set forth in paragraph 3 above based upon the closing sales price of a MLP Unit on the Determination Date as reported by such reporting service as the Board may choose.

6.             If for any year a MLP Phantom Unit Payment is made pursuant to paragraph 4 that is greater than the payment that would have been made based on the combined results for the Partnership Phantom Unit and a MLP Phantom Unit with respect to such year, if the Phantom Unit Payment were instead determined on a combined basis rather than on a separate basis for the Partnership and the MLP, then the amount of the MLP Phantom Unit Payment paid for such year in excess of what would have been paid for such year if the payment were determined on a combined basis shall be carried forward to subsequent years and shall be applied as an offset against any Partnership Phantom Unit Payment in any such subsequent years that is otherwise payable, until such MLP carry forward amount has been fully used as an offset to any such Partnership Phantom Unit Payments.  No Partnership Phantom Unit Payment shall be made unless there is no MLP carry forward amount for such year or such MLP carry forward amount is first fully applied as an offset in such year.

7.             The “Determination Date” with respect to a Phantom Option shall be the last day of the Partnership’s or the MLP’s (as the case may be) fiscal year (currently, December 31),

B-4

except in the event of the termination of the Executive’s employment with the Employer prior to the end of the Partnership’s or the MLP’s (as the case may be) fiscal year, in which case the Determination Date shall be the Date of Termination.

8.             The Phantom Unit Payment shall be made in cash; however, with respect to a MLP Phantom Unit Payment the Executive may elect to receive such MLP Phantom Unit Payment all in freely tradeable MLP Units, in cash or in any combination thereof, and with respect to a Partnership Phantom Unit Payment the Executive may elect to receive such Partnership Phantom Unit Payment all in “restricted” phantom Partnership Units (notional units representing a corresponding partnership interest in the Partnership) with such restrictions concerning payments and transfers as may be applicable to similar phantom awards under other long-term incentive plans of the Employer, in cash or in any combination thereof.  The Phantom Unit Payment shall be made to the Executive, or to his beneficiaries, heirs or estate in the event of his death, as soon as practicable, but in no event more than sixty (60) days after the Determination Date.

9.             Subject to Section 10 below, the Executive shall acquire a vested and non-forfeitable interest in the Phantom Option as of the last day of the Partnership’s or the MLP’s (as the case may be) fiscal year if the Executive is employed by the Employer on such day.

10.           In the event of the termination of the Executive’s employment by the Employer without Cause, by the Executive for Good Reason, or by reason of the Executive’s death or Disability, (a) the Executive shall acquire a vested and non-forfeitable interest in the Phantom Option as of the Date of Termination, (b) the Option Period shall end on the Date of Termination and (c) the Phantom Unit Payment shall be made as soon as practicable, but in no event more than sixty (60) days after the Date of Termination. In the event of the termination of the Executive’s employment with the Employer by the Employer for Cause or by the Executive without Good Reason, the Executive shall forfeit the Phantom Option as of the Date of Termination and the Employer, the Partnership and the MLP shall have no further obligations to the Executive with respect to such Phantom Option.

11.           Upon payment of the Phantom Unit Payment with respect to a Phantom Option, such Phantom Option shall automatically terminate and be of no further force or effect.

12.           The Employer shall withhold or shall cause to be withheld all applicable income taxes and employment taxes from the Phantom Unit Payment as may be required by law.

13.           The Phantom Option, or any interest in it, shall not be assignable by the Executive and shall not be subject to attachment, lien, levy or other creditors’ rights under state or Federal law. The Phantom Unit Payments shall be payable from the general assets of the Employer, the MLP or the Partnership, as the case may be, or pursuant to such other means as they deem appropriate, and the Executive shall not be entitled to look to any source for payment of such benefits other than the general assets of the Employer, the MLP or the Partnership, as the case may be.
