(d) Upon execution of the Prior Agreement, Buyer advanced Seller the sum of $1,300,000 U.S. The advance of such amount was conditioned upon Seller’s execution of the Promissory Note in the form attached as Exhibit D-1 to the Prior Agreement and the Security Agreement in the form attached as Exhibit D-2 to the Prior Agreement providing Buyer a security interest in the following: (the “Prior Collateral”)

(i)

four petroleum storage tanks, having approximately 290,000 barrels total capacity along with Seller’s associated property leased from the BND in Brownsville, Texas pursuant to BND Lease No. 3165, as amended, and associated access to a 12 inch pipeline header to public docks at the Port of Brownsville (the “Petroleum Tanks”), and

(ii)

six LPG storage tanks (Tanks #400, 401, 500, 501, 502, 503) having approximately 300,000 gallons total capacity, located upon Seller’s property leased from the BND in Brownsville, Texas pursuant to BND Lease No. 2823, as amended, (the “LPG Tanks”).

(e) Upon the Closing of this Agreement, the Seller will reduce the principal amount of the Promissory Note by $300,000, said amount to be a reduction in the Purchase Price, and Parties agree to (i) substitute the eight inch (8”) pipeline included in the Pipeline Assets (the “New Collateral”) for the Prior Collateral, (ii) amend the Promissory Note in the form of Exhibit D-1(Amended) in order to, among other things, extend the repayment schedule of the advance of the remaining principal of $1,000,000 to one year after the Date of Closing and (iii) amend the Security Agreement in the form of the attached Exhibit D-2 (Amended) to extend the security interest in said agreement to the New Collateral described hereinabove. Upon Closing, Seller will repay the Secured Debt Lenders such amount as will cause them to release any and all Liens they may hold with respect to the Prior Collateral and the New Collateral and Seller will take the necessary steps to have the Secured Debt Lenders to do the same.

(f) The Prior Collateral will be specifically included within the Brownsville Terminal Assets conveyed to Buyer. Upon payment of the amended Promissory Note in full, Buyer shall mark the Promissory Note “Paid In Full,” return such Promissory Note to Seller and release its security interest in the New Collateral and provide Seller with appropriate documentation of such release in recordable form. If Closing does not occur under this Agreement for any reason, then Seller, at Seller’s sole option, will either:

(i) promptly provide Buyer with a bill of sale conveying all right and title to the Prior Collateral to Buyer and assignment of the BND Lease No. 3165 (with the consent by BND to the assignment and subordination of BND’s Liens on the Petroleum Tanks) and Seller shall thereafter lease the Petroleum Tanks and LPG Tanks from Buyer on a month to month basis, at a monthly lease fee of $10,000, until such time that Seller repurchases the Petroleum Tanks and LPG Tanks from Buyer by paying Buyer the amount of $1,300,000 in which event Buyer will promptly provide Seller with a bill of sale conveying all right and title to the LPG Tanks and Petroleum Tanks (including an assignment of BND Lease No. 3165) to Seller; or

(b) allocating the amount of the Purchase Price for the Acquired Assets on the Form in which the Parties will attempt to reach agreement as to allocation of the Purchase Price. However, if they are unable to agree as to the allocation to any asset, each Party will prepare its Form allocating the portion of the Purchase Price to each such asset upon which they disagree in the manner as each may determine in its sole discretion without regard to the manner in which the other Party allocates an amount of the Purchase Price to such asset on its Form.

If pursuant to Schedule 6.3(d)(i) it is determined that the Minimum Requirement was not satisfied as of the Effective Time, then Seller shall pay to Buyer the Deficiency Amount as described in and determined pursuant to such Schedule 6.3(d)(i), such payment to be made by Seller to Buyer within five (5) Business Days of such determination.

Buyer acknowledges and agrees that it has fully exercised all of its rights, pursuant to the Prior Agreement and otherwise, to investigate, inspect, audit, study and test the Brownsville Leases, including the soil, groundwater and all other physical features, for the existence of Environmental Conditions and violations of Environmental Laws (the “Environmental Audit”). The Environmental Audit has been completed. The cost and expense of the Environmental Audit shall be borne by Buyer.

(ii)

Buyer has conferred with Governmental Authorities and reviewed and copied all records of Governmental Authorities with respect to the Brownsville Leases in connection with the Environmental Audit.

(iii)

Buyer has no further rights or options pursuant to the Prior Agreement or this Agreement with respect to the Environmental Audit.

(f) Employee and Benefit Matters.

(i)

Seller or RVEP shall make available to Buyer all U.S. Employees to discuss potential employment with Buyer or an Affiliate of Buyer (such entity that makes employment offers being the “Buyer Employer”). Seller shall provide Buyer with an updated list of the U.S. Employees within five (5) days of the date upon which any change therein has occurred. On or before the Closing Date, but effective as of the Closing Date, and conditioned upon the occurrence of the Closing, Buyer shall cause the Buyer Employer to make offers of employment to the U.S. Employees who are employed by Seller or RVEP immediately prior to the Closing Date, and who are selected by the Buyer Employer in its sole discretion upon written notice to Seller at least five days prior to the Closing Date. The terms and conditions of each such offer of employment shall be on terms and conditions determined by the Buyer Employer, in its sole discretion, that are consistent with the provisions of this Section 6.3(f). All offers of employment shall be subject to the Buyer Employer’s policies concerning background and security checks and drug/substance abuse testing. As used in this Agreement, the term “Continuing Employees” means each U.S. Employee who accepts an offer of employment from the Buyer Employer as provided in the preceding provisions of this paragraph and reports to work and commences active duty for the Buyer Employer. The “Hire Date” for each U.S. Employee who accepts an employment offer from the Buyer Employer pursuant to the terms of this paragraph and who actually becomes employed by the Buyer Employer in accordance with such offer shall be the Closing Date.

(ii)

For a period of not less than one year beginning on the Closing Date, Buyer shall cause the Buyer Employer to provide the Continuing Employees while employed by the Buyer Employer during such period with employee benefits on a basis substantially similar to those provided to similarly situated employees of the Buyer Employer. From and after the applicable Hire Date, for purposes of (x) eligibility to participate in, and vesting under, the employee benefit plans that are intended to be qualified under Section 401 of the Internal Revenue Code and that are maintained after such date by the Buyer Employer and (y) eligibility and benefit determination under the vacation policies maintained by the Buyer Employer, Buyer shall cause the Buyer Employer to recognize each Continuing Employee’s years of service for corresponding purposes that were credited prior to such Continuing Employee’s Hire Date under the corresponding Seller Plans in which the Continuing Employee participated immediately prior to the Closing Date. Promptly after each Continuing Employee’s Hire Date, Seller shall provide written notice to Buyer of such prior service credit.

(iii)

On or before each Continuing Employee’s Hire Date, Seller shall (A) take any necessary action to fully vest as of such date the Continuing Employee’s account balances and other accrued benefits under all Seller Plans that are intended to be qualified under Section 401 of the Internal Revenue Code and (B) take such actions, if any, as may be necessary to permit the continuation of loan repayments after such date by the Continuing Employee if he or she has an outstanding loan from any such Seller Plan as of such date. Such loan repayments shall be made directly by the Continuing Employee to the applicable Seller Plan, and shall be permitted so long as the Continuing Employee remains employed by the Buyer Employer.

(iv)

Buyer Employer shall not from and after the Closing Date, have any responsibility or liability with respect to the Seller Plans. Any and all liabilities for severance payments and other amounts owed with respect to a U.S. Employee (A) who is not offered employment with the Buyer Employer, (B) who is otherwise not employed by the Buyer Employer, or (C) whose employment with Seller or RVEP and their Affiliates is terminated for any reason whatsoever shall, in each such case, remain the responsibility of Seller.

(v)

Nothing in this Agreement shall require or be construed or interpreted as requiring the Buyer Employer to continue the employment of any of Seller’s employees following the Closing Date, or to prevent the Buyer Employer from changing the terms and conditions of employment (including compensation and benefits) of any of their employees following the Closing Date. Without limiting the generality of Section 12.4, this Section 6.3(f) is not intended to confer upon any U.S. Employee or Continuing Employee any rights or remedies hereunder.

(g) Schedules. If, on the date on which this Agreement is executed by all Parties hereto, any schedule to this Agreement has not been completed, then such schedule shall be completed as promptly as commercially practical and such completed schedule shall be treated as if it had been delivered on the date of this Agreement. No representation or warranty contained in this Agreement shall be deemed breached as of the date of the making of such representation or warranty by reason of the fact that the relevant schedule was incomplete as of such date, provided that a complete schedule that renders true such representation or warranty is delivered pursuant to this Section 6.3(g) at least five (5) Business Days before the Closing.

(h) Obligation of Removal of Substance from Petroleum Tanks. By the Closing Date:

(i)

Seller will complete its removal and proper disposal of, at its sole cost and expense, any and all liquids, solids and other substances contained within the Petroleum Tanks and other tanks and associated piping. Such contents and substances shall be removed by Seller and properly and legally disposed of off site. Upon removal of the contents from the Petroleum Tanks, Seller shall power wash the Petroleum Tanks and shall render them in a dry and gas free condition, suitable for inspection;

(ii)

all plastic liners located in the two slop pits (and any liquids, solids and other substances contained in or on them) shall be removed and legally disposed of off site at Seller’s sole cost and expense; and

(iii)

any drums and their contents located on the BND Lease No. 3165 site shall be removed by Seller and properly and legally disposed of off site at Seller’s sole cost and expense.

(iv)

If the above action in (i), (ii) and (iii) are not performed by the Closing Date, Buyer will perform such actions in accordance with Section 8.11.

(i) Additional Agreements. At the Closing, the Parties shall execute and deliver:

(i)

a “Pipeline Service Agreement” in the form of Exhibit E, pursuant to which Buyer will maintain and operate the U.S. portion only of Seller’s pipelines between Brownsville and Matamoros, and

(ii)

an “LPG Transportation Agreement” in the form of Exhibit F, pursuant to which Seller (or its affiliates) will transport, terminal and redeliver LPG for Buyer from the Brownsville Terminal Site to Seller’s Matamoros Terminal Site.

(j) Revenues, Expenses, and Remittance of Monies. All revenues and expenses, whenever received or paid, which are attributable to the Acquired Assets for the period prior to the Effective Time shall belong to Seller and all revenues or expenses attributable to the Acquired Assets for the period from and after the Effective Time shall belong to Buyer. If a Party receives or pays any monies from or to a third Person, including, without limitation, from PMI pursuant to the PMI Contract that are owed to the other Party, the receiving Party will promptly remit such monies to such other Party.

ARTICLE XIII

NON-COMPETITION REQUIREMENT, EXCLUSIVITY, PMI EASEMENT AND RIGHT OF FIRST OFFER

SECTION 13.1 Non-Competition Requirement; Exclusivity.

(a) To the extent permitted by law and subject to Section 13.1(b), from and after the Closing Date, and while Buyer is transporting or desires to transport LPG in the Pipeline Assets for delivery to the Matamoros Terminal Site and Buyer is not shipping products other than LPG in the Seadrift Pipeline, Seller or its Affiliates, including, without limitation, the Companies, will not or will not permit other parties, other than Buyer and its Affiliates, including TransMontaigne Partners L.P. (and Seller and its Affiliates on behalf of Buyer and its Affiliates, including TransMontaigne Partners L.P.,), to (i) transport LPG on or in the Mexican portion of the Pipeline Assets or (ii) store or handle LPG in the Matamoros Terminal Site. Subject to Section 13.1(b), the foregoing restriction will be a condition imposed by Seller on any purchaser of the Pipeline Assets, the Matamoros Terminal Site or the Shares. The provisions of this Section 13.1(a) shall terminate upon any failure to satisfy the conditions set forth in Section 13.1(b).

(b) Buyer shall exclusively engage the services of Seller and utilize the Pipeline Assets, to the extent of the transportation capacity in the Pipeline Assets, for the transportation of all quantities of LPG which Buyer, its Affiliates or agents, including TransMontaigne Partners L.P., deliver (i) pursuant to the PMI Contract or (ii) otherwise to north eastern Mexico, including without limitation the geographic region served by the Pipeline Assets or the Matamoros Terminal Site.

SECTION 13.2 PMI Easement.

(a) From and after the Closing Date and prior to the final sale or other disposition of the PMI Easement or of all or any portion of the real property across which such easement is located (“Subject Property”) by Seller or its Affiliates, Seller must first offer (“Offer”) the Subject Property for sale to Buyer. The price ("Offer Price") at which the Seller will be required to offer the Subject Property will be the price at which any proposed third party purchaser ("Proposing Purchaser") has offered in writing to purchase the Subject Property from the Seller or its Affiliates and which the Seller or its Affiliates are prepared to accept. If Seller or its Affiliates are unable to obtain a Proposing Purchaser or otherwise determine not to seek a Proposing Purchaser, the Offer Price will be the price negotiated between Seller and Buyer for the Subject Property. Each Offer required to be made by the Seller pursuant to this Section 13.2 must be made by a written notice (the "Offer Notice") which will state that the Offer is being made pursuant to this Section 13.2 and will set forth a description of the Subject Property, the name or names of the Proposing Purchaser, and the price (and the terms of payment and other material consideration for the Subject Property) offered by such Proposing Purchaser. A copy of the written offer from the Proposing Purchaser that the Seller or its Affiliates are prepared to accept must be attached to each Offer Notice.

(b) Within 15 days from the date of receipt of the Offer Notice ("Reply Period"), the Buyer must deliver to Seller a reply notice ("Reply Notice") accepting or rejecting the Offer of the Seller with respect to the Subject Property. If by such Reply Notice Buyer accepts the Offer made by the Seller with respect to the Subject Property, the Reply Notice will constitute an agreement binding on the Seller and its Affiliates and the Buyer to sell and purchase the Subject Property on the date specified in Section 13.3 (d), at an aggregate purchase price equal to the Offer Price and on the other terms and consideration proposed by the Proposing Purchaser.

(c) If Buyer does not accept the Offer within the Reply Period, Seller may sell not less than all of the Subject Property included in the Offer at any time within, but not subsequent to, six months after the expiration of the Reply Period; provided, however, that no sale of the Subject Property will be made at any price lower than the Offer Price or to any person or persons other than those specified in the Offer Notice. If, after the lapse of such six month period, the Subject Property has not been sold or disposed of, all the provisions of this Section 13.3 will apply to any future sale or disposition of any of the Subject Property by the Seller or its Affiliates.

(d) Each transaction with respect to the sale of the Subject Property pursuant to this Section 13.3 will be closed at such time and place as is agreed upon by the Parties or, if no such agreement is reached, at the principal office of the Buyer on the 90th day following the date of timely delivery of the Reply Notice given in connection with such transaction or, if such day shall not be a Business Day, on the next succeeding Business Day.

SECTION 13.3 Right of First Offer.

If at any time subsequent to the Closing Date either Seller or Penn Octane International LLC, a Delaware limited liability company (“International”), decides to sell either (i) the Shares in the Companies or (ii) the Pipeline Assets and the Matamoros Terminal Site (the “Offered Assets”), then Seller shall advise Buyer of its desire to sell same (the “Purchase Offer”). Buyer shall have ninety days following receipt of the Purchase Offer to make an offer to purchase the Offered Assets. If the offer is acceptable to Seller, then Seller and Buyer shall negotiate and enter into a purchase and sale agreement containing terms and conditions pursuant to which Seller and International shall sell, assign, transfer and convey to Buyer and Buyer shall purchase and acquire from the Seller and International, all right, title and interest of Seller and International in and to the Offered Assets free and clear of any Liens or Encumbrances (other than Permitted Encumbrances). In the event that the parties enter into a purchase and sale agreement, then Buyer shall have the right to assign the purchase and sale agreement to a third Person. If Buyer does not make an offer to purchase the Offered Assets within the ninety day period, Seller or International may proceed to sell the Offered Assets to a third Person. If Buyer, Seller and International do not enter into a purchase and sale agreement within one hundred twenty (120) days following delivery of the Purchase Offer, Seller or International or both may proceed to sell the Offered Assets to a third Person.
