TRANSMONTAIGNE INC. RECEIVES REVISED PROPOSAL FROM MORGAN STANLEY

Monday, June 19, 2006

Immediate Release

Denver, Colorado — TransMontaigne Inc. (NYSE: TMG) today announced that it has received a revised proposal from Morgan Stanley Capital Group Inc. (“Morgan Stanley”) to acquire the Company at a price of $11.35 per share, in cash. On June 18, 2006, Morgan Stanley delivered to us a new proposal that increases the cash payment to holders of our capital stock to $11.35 per share. A copy of Morgan Stanley’s new proposal is filed as “Item 4. Purpose of Transaction” in Amendment No. 5 to Schedule 13D, which was filed by Morgan Stanley with the Securities and Exchange Commission today.

Our Board of Directors will meet today to evaluate Morgan Stanley’s revised proposal to determine whether it currently constitutes, or may become, a superior proposal pursuant to the provisions of the Company’s existing merger agreement with SemGroup, L.P. (“SemGroup”). If our Board of Directors determines, after consultation with its advisors, that Morgan Stanley’s new proposal currently constitutes a superior proposal, then the Board of Directors will provide notice to SemGroup that TransMontaigne is prepared to terminate the amended and restated SemGroup merger agreement of May 22, 2006, and enter into the new Morgan Stanley merger agreement.

If this notice is given to SemGroup on Monday, June 19, 2006, SemGroup will have until the close of business on Thursday, June 22, 2006, to provide our Board of Directors with a revised merger agreement that our Board of Directors determines is at least as favorable to our stockholders as the Morgan Stanley merger agreement. Pending the outcome of this process, the amended and restated SemGroup merger agreement of May 22, 2006, remains in effect.

Additional Information and Where to Find It

On June 7, 2006, we filed updated preliminary proxy materials regarding the proposed merger with SemGroup with the Securities and Exchange Commission (“SEC”). TransMontaigne currently expects to file amended proxy materials with the SEC as soon as reasonably practicable. Upon receipt of all necessary approvals, TransMontaigne then will mail to its stockholders definitive materials regarding the transaction as soon as practicable thereafter. Such proxy materials will contain information about TransMontaigne, the proposed merger and related matters. Stockholders are urged to read the amended proxy statement carefully when it is available, as it will contain important information that stockholders should consider before making a decision about the merger.

In addition to receiving the proxy statement from TransMontaigne by mail, stockholders also will be able to obtain the proxy statement, as well as other filings containing information about TransMontaigne, without charge, from the SEC website (http://www.sec.gov) or, without charge, from TransMontaigne (http://www.transmontaigne.com)

This announcement is neither a solicitation of proxy, an offer to purchase, nor a solicitation of an offer to sell shares of TransMontaigne. TransMontaigne and its executive officers and directors may be deemed to be participants in the solicitation of proxies from TransMontaigne’s stockholders with respect to the proposed merger. Information regarding any interests that TransMontaigne’s executive officers and directors may have in the transaction will be set forth in the proxy statement.
