·                  Operating income for the quarter ended September 30, 2014 was $8.3 million compared to $6.8 million for the quarter ended September 30, 2013, principally due to the following:

·                  Revenue was $35.7 million compared to $38.4 million due to decreases in revenue at the Gulf Coast, Brownsville and Southeast terminals of approximately $1.0 million, $1.4 million and $0.5 million, respectively, offset by an increase in revenue at the River terminals of approximately $0.2 million.  Revenue for the Midwest terminals was consistent period over period.

·                  A decrease in direct general and administrative expenses of approximately $0.1 million.

Our terminaling services agreements are structured as either throughput agreements or storage agreements.  Most of our throughput agreements contain provisions that require our customers to throughput a minimum volume of product at our facilities over a stipulated period of time, which results in a fixed amount of revenue to be recognized by us.  Our storage agreements require our customers to make minimum payments based on the volume of storage capacity made available to the customer under the agreement, which results in a fixed amount of revenue to be recognized by us.  We refer to the fixed amount of revenue recognized pursuant to our terminaling services agreements as being “firm commitments.”  Revenue recognized in excess of firm commitments and revenue recognized based solely on the volume of product distributed or injected are referred to as “variable.”  Our revenue was as follows (in thousands):

The amount of revenue recognized as “firm commitments” based on the remaining contractual term of the terminaling services agreements that generated “firm commitments” for the nine months ended September 30, 2014 was as follows (in thousands):

BOSTCO is a terminal facility construction project for approximately 7.1 million barrels of storage capacity at an estimated cost of approximately $535 million. BOSTCO is located on the Houston Ship Channel and began initial commercial operations in the fourth quarter of 2013.  Frontera is a terminal facility located in Brownsville, Texas that encompasses approximately 1.5 million barrels of light petroleum product storage capacity, as well as related ancillary facilities.

RECENT DEVELOPMENTS

Change in control of the ownership of our general partner.  Effective July 1, 2014, Morgan Stanley consummated the sale of its 100% ownership interest in TransMontaigne Inc. to NGL Energy Partners LP (“NGL”). TransMontaigne Inc. is the indirect parent and sole member of TransMontaigne GP, which is our general partner. The sale resulted in a change in control of Partners, but did not result in a deemed termination of Partners for tax purposes.

In addition to the sale of our general partner to NGL, NGL acquired the common units owned by TransMontaigne Inc. and affiliates of Morgan Stanley, representing approximately 20% of our outstanding common units, and assumed Morgan Stanley Capital Group’s obligations under our light-oil terminaling service agreements in Florida and the Southeast regions, excluding the Collins/Purvis tankage (collectively, the “NGL Acquisition”). All other terminaling services agreements with Morgan Stanley Capital Group remained with Morgan Stanley Capital Group. Pursuant to the

3

terms and conditions of the NGL Acquisition, in exchange for Partners’ consent to the assignment of terminaling services agreements to NGL, an affiliate of Morgan Stanley issued a financial guarantee to Partners on certain negotiated terms, including termination of the financial guarantee upon delivery of a letter of credit from NGL.  In addition, we amended our existing credit facility to, among other items, consent to the change of control of Partners resulting from the NGL Acquisition. The NGL Acquisition did not involve the sale or purchase of any of our common units held by the public and our common units continue to trade on the New York Stock Exchange.

Termination of discussions to exchange our common units for NGL common units.  On July 10, 2014, NGL submitted a non-binding, unsolicited proposal (the “Proposal”) to the Conflicts Committee of the board of directors of TransMontaigne GP, pursuant to which each outstanding common unit of Partners would have been exchanged for one common unit of NGL.  On August 15, 2014, NGL and our Conflicts Committee jointly announced that, after several discussions, an agreement on the price to be offered to Partners’ unitholders could not be reached, and both parties had terminated discussions regarding the Proposal to acquire the outstanding common units of Partners.  We do not know whether or when NGL may make another proposal similar to, or with similar objectives as, the Proposal.

Changes in our board composition and management team.  In connection with the consummation of the NGL Acquisition, on July 1, 2014, Stephen R. Munger, Goran Trapp and Martin S. Mitchell, each employees of Morgan Stanley, resigned from the board of directors of TransMontaigne GP. To fill the vacancies resulting from the resignation of the Morgan Stanley directors, Atanas H. Atanasov, Benjamin Borgen, David C. Kehoe and Donald M. Jensen, each employees of NGL, were appointed to the board of directors of TransMontaigne GP effective July 1, 2014.

On August 25, 2014, Jerry R. Masters, David A. Peters and Jay A. Wiese, who qualified as independent directors under the applicable listing standards of the New York Stock Exchange, resigned from the board of directors of TransMontaigne GP.  Mr. Masters served as the Chairman of the Audit and Compensation Committees and as a member of the Conflicts Committee. Mr. Peters served as the Chairman of the Conflicts Committee and as a member of the Audit and Compensation Committees. Mr. Wiese served as a member of the Audit, Compensation and Conflicts Committees.

On September 4, 2014, the board of directors of TransMontaigne GP appointed Robert A. Burk to serve as a director.  Mr. Burk serves as a member of the Audit and Compensation Committees, as the chair of the Conflicts Committee, and as the presiding director over non-management and independent directors.  Mr. Burk qualifies as an independent director under the applicable listing standards of the New York Stock Exchange.

On September 24, 2014, the board of directors of TransMontaigne GP appointed Steven A. Blank and Lawrence C. Ross to serve as directors. Mr. Blank serves as the chair of the Audit Committee and as a member of the Compensation and Conflicts Committees. Based upon his education and employment experience, Mr. Blank qualifies as an “audit committee financial expert” as defined by the Securities and Exchange Commission.  Mr. Ross serves as the chair of the Compensation Committee and as a member of the Audit and Conflicts Committees.  Mr. Blank and Mr. Ross both qualify as independent directors under the applicable listing standards of the New York Stock Exchange.

On October 16, 2014, Charles L. Dunlap notified Partners of his intention to retire from his position as Chief Executive Officer of our general partner and as President, Chief Executive Officer and member of the board of directors of TransMontaigne Inc., and the other subsidiaries of Partners and TransMontaigne Inc., each to be effective November 7, 2014.  As a result of Mr. Dunlap’s resignation, on October 20, 2014, the board of directors of TransMontaigne GP appointed Frederick W. Boutin to serve as Chief Executive Officer of our general partner, effective November 7, 2014. Mr. Boutin has also been appointed to serve as the President and Chief Executive Officer of TransMontaigne Inc.,

4

effective November 7, 2014.  In connection with Mr. Boutin’s appointment to Chief Executive Officer, on October 20, 2014, the board of directors of TransMontaigne GP appointed Robert T. Fuller to serve as the Executive Vice President, Chief Financial Officer, Chief Accounting Officer and Treasurer of our general partner, effective November 7, 2014. Mr. Fuller has also been appointed to serve as the Executive Vice President, Chief Financial Officer and Treasurer of TransMontaigne Inc., effective November 7, 2014.

BOSTCO.  As of September 30, 2014, the second phase of the BOSTCO construction project, encompassing 900,000 barrels of diesel storage, has been placed into service.  With the addition of this second phase, combined with the initial phase becoming fully operational in the second quarter of 2014, BOSTCO has 57 storage tanks that are operational, with a fully subscribed capacity of approximately 7.1 million barrels.

Re-contracting.  Effective September 16, 2014, we amended our long-term terminaling services agreement with Metroplex Energy, a wholly-owned subsidiary of RaceTrac Petroleum Inc. (“Metroplex”), to include the use of gasoline, ethanol and diesel tankage at our Cape Canaveral, Port Manatee and Port Everglades South terminals located in Florida.  The tankage at Cape Canaveral and Port Everglades South became immediately available to Metroplex on September 16, 2014.  The tankage at Port Manatee is expected to become available to Metroplex by the fall of 2015, upon the completion of certain enhancements at this facility. We had previously entered into an agreement with Metroplex that was effective in September of 2013 relating to the use of storage capacity at our Tampa, Florida terminal.  The amended agreement brings the aggregate capacity of our tankage under contract with Metroplex in Florida to approximately 2.17 million barrels.

The tankage related to this new amendment with Metroplex was previously used by NGL under our Florida and Midwest Terminaling Services Agreement. Simultaneous with the entry into the Metroplex agreement, we amended the Florida and Midwest Terminaling Services Agreement to immediately terminate NGL’s obligations relating to the tank capacity at our Cape Canaveral and Port Everglades South terminals, and to terminate NGL’s obligation at our Port Manatee terminal effective March 14, 2015.  We expect that the amendments to the Metroplex agreement will generate approximately the same annual revenue as the NGL agreement generated with respect to those tanks.

On October 31, 2014, NGL provided us the required 18 months’ prior notice that it will terminate its remaining obligations under the Florida and Midwest terminaling services agreement effective April 30, 2016, which constitutes NGL’s light-oil terminaling capacity at our Port Everglades, Florida North terminal.

Distribution.  On October 13, 2014, we announced a distribution of $0.665 per unit for the period from July 1, 2014 through September 30, 2014. This distribution is payable on November 7, 2014 to unitholders of record on October 31, 2014.

LIQUIDITY AND CAPITAL RESOURCES

TransMontaigne Partners also released the following statements regarding its current liquidity and capital resources:

·                  Our credit facility provides for a maximum borrowing line of credit equal to $350 million.  The credit facility allows us to make up to $225 million of investments in BOSTCO and to make an additional $75 million of “other permitted joint venture investments”, which may also include additional investments in BOSTCO. The terms of the credit facility also permit us to issue senior unsecured notes. The credit facility became effective March 9,

2011 and expires on March 9, 2016.  At September 30, 2014, our outstanding borrowings were $252 million.

·                  Consolidated EBITDA generated for the three and nine months ended September 30, 2014 was $17.8 million and $56.5 million, resprectively.

·                  Management and the board of directors of our general partner have approved additional investments in BOSTCO and expansion capital projects at our existing terminals that currently are, or will be, under construction with estimated completion dates that extend into the third quarter of 2015. At September 30, 2014, the remaining expenditures to complete the approved additional investments and expansion capital projects are estimated to be approximately $15 million. We expect to fund our future investments and expansion capital expenditures with additional borrowings under our credit facility.

·                  We have funded our investments in the BOSTCO construction project utilizing additional borrowings under our credit facility.  Upon completion of the initial phases of the project, we expect our total payments for the project to be approximately $235 million.  At September 30, 2014, our investment in the BOSTCO project was approximately $228 million.

·                  Our primary liquidity needs are to fund our working capital requirements, distributions to unitholders, approved investments, approved capital projects and approved future expansion, development and acquisition opportunities. We expect to initially fund investments, capital projects and future expansion, development and acquisition opportunities with additional borrowings under our credit facility. After initially funding these expenditures with borrowings under our credit facility, we may raise funds through additional equity offerings and debt financings. The proceeds of such equity offerings and debt financings may then be used to reduce our outstanding borrowings under our credit facility.

ATTACHMENT B

DISTRIBUTABLE CASH FLOW

The following summarizes our distributable cash flow for the periods indicated (in thousands):

Distributable cash flow and Consolidated EBITDA are not computations based upon generally accepted accounting principles.  Consolidated EBITDA is calculated consistent with the provisions our credit facility and is a financial performance measure used in the calculation of our leverage ratio requirement. The amounts included in the computation of our distributable cash flow and Consolidated EBITDA are derived from amounts separately presented in our consolidated financial statements, notes thereto and “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Quarterly Report on Form 10-Q for the three months ended September 30, 2014, which was filed with the Securities and Exchange Commission on November 7, 2014. Distributable cash flow and Consolidated EBITDA should not be considered in isolation or as an alternative to net earnings or operating income, as an indication of

9

our operating performance, or as an alternative to cash flows from operating activities as a measure of liquidity. Distributable cash flow and Consolidated EBITDA are not necessarily comparable to similarly titled measures of other companies. Distributable cash flow and Consolidated EBITDA are presented here because they are widely accepted financial indicators used to compare partnership performance. We believe that these measures provide investors an enhanced perspective of the operating performance of our assets, the cash we are generating and our ability to make distributions to our unitholders and our general partner.
