The undersigned hereby acknowledges receipt and review of the prospectus dated June 18, 1999 of Leviathan Gas Pipeline Partners, L.P., a Delaware limited partnership, and Leviathan Finance Corporation, a 1 2 Delaware corporation (together, "Leviathan"), and this Letter of Transmittal, which together describe the offer of Leviathan (the "exchange offer") to exchange Leviathan's 10 3/8% Series B Senior Subordinated Notes due 2009 (the "Series B notes"), which have been registered under the Securities Act of 1933, as amended (the "Securities Act"), pursuant to a registration statement of which the prospectus is a part, for a like principal amount of Leviathan's issued and outstanding 10 3/8% Series A Senior Subordinated Notes due 2009 (the "Series A notes"). Certain terms used but not defined herein have the respective meanings given to them in the prospectus. Leviathan reserves the right, at any time or from time to time, to extend the exchange offer at its discretion, in which event the term "expiration date" shall mean the latest date to which the exchange offer is extended. Leviathan shall give notice of any extension by giving oral, confirmed in writing, or written notice to the exchange agent and by making a public announcement by press release to the Dow Jones News Service prior to 9:00 a.m., New York City time, on the first business day after the previously scheduled expiration date. The term "business day" shall mean any day that is not a Saturday, Sunday or day on which banks are authorized by law to close in the State of New York. This Letter of Transmittal is to be used by a holder of Series A notes if original Series A notes, if available, are to be forwarded herewith or an agent's message is to be used if delivery of Series A notes is to be made by book-entry transfer to the account maintained by the exchange agent at The Depository Trust Company (the "book-entry transfer facility") pursuant to the procedures set forth in the prospectus under the caption "The Exchange Offer -- Procedures for Tendering Series A Notes." Holders of Series A notes whose Series A notes are not immediately available, or who are unable to deliver their Series A notes and all other documents required by this Letter of Transmittal to the exchange agent on or prior to the expiration date, or who are unable to complete the procedure for book-entry transfer on a timely basis, must tender their Series A notes according to the guaranteed delivery procedures set forth in the prospectus under the caption "The Exchange Offer -- Procedures for Tendering Series A Notes -- Guaranteed Delivery."

Subject to and effective upon the acceptance for exchange of the principal amount of Series A notes tendered in accordance with this Letter of Transmittal, the undersigned hereby exchanges, assigns and transfers to Leviathan all right, title and interest in and to the Series A notes tendered for exchange hereby. The undersigned hereby irrevocably constitutes and appoints the exchange agent, the agent and attorney-in-fact of the undersigned (with full knowledge that the exchange agent also acts as the agent of Leviathan in connection with the exchange offer) with respect to the tendered Series A notes with full power of substitution to: - deliver such Series A notes, or transfer ownership of such Series A notes on the account books maintained by the book-entry transfer facility, to Leviathan and deliver all accompanying evidences of transfer and authenticity, and - present such Series A notes for transfer on the books of Leviathan and receive all benefits and otherwise exercise all rights of beneficial ownership of such Series A notes, all in accordance with the terms of the exchange offer. The power of attorney granted in this paragraph shall be deemed to be irrevocable and coupled with an interest. The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, exchange, assign and transfer the Series A notes tendered hereby and to acquire the Series B notes issuable upon the exchange of such tendered Series A notes, and that Leviathan will acquire good and unencumbered title thereto, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim, when the same are accepted for exchange by Leviathan. The undersigned acknowledge(s) that this exchange offer is being made in reliance upon interpretations contained in no-action letters issued to third parties by the staff of the Securities and Exchange Commission (the "SEC"), including Exxon Capital Holdings Corporation, SEC No-Action Letter (available April 13, 1989), Morgan Stanley & Co. Inc., SEC No-Action Letter (available June 5, 1991) (the "Morgan Stanley Letter") and Mary Kay Cosmetics, Inc., SEC No-Action Letter (available June 5, 1991), that the Series B notes issued in exchange for the Series A notes pursuant to the exchange offer may be offered for resale, resold and otherwise transferred by holders thereof (other than a broker-dealer who purchased Series A notes exchanged for such Series B notes directly from Leviathan to resell pursuant to Rule 144A or any other available exemption under the Securities Act), without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such Series B notes are acquired in the ordinary course of such holders' business and such holders are not participating in, and have no arrangement with any person to participate in, the distribution of such Series B notes. The undersigned specifically represent(s) to Leviathan that: - any Series B notes acquired in exchange for Series A notes tendered hereby are being acquired in the ordinary course of business of the person receiving such Series B notes, whether or not the undersigned; - the undersigned is not participating in, and has no arrangement with any person to participate in, the distribution of Series B notes; - neither the undersigned nor any such other person is an "affiliate" (as defined in Rule 405 under the Securities Act) of Leviathan or a broker-dealer tendering Series A notes acquired directly from Leviathan. If the undersigned is not a broker-dealer, the undersigned represents that it is not engaged in, and does not intend to engage in, a distribution of Series B notes. If the undersigned is a broker-dealer that will receive Series B notes for its own account in exchange for Series A notes that were acquired as a result of market- 4 5 making activities or other trading activities, it acknowledges that it will deliver a prospectus in connection with any resale of such Series B notes; however, by so acknowledging and by delivering a prospectus, the undersigned will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. The undersigned acknowledges that if the undersigned is participating in the exchange offer for the purpose of distributing the Series B notes: - the undersigned cannot rely on the position of the staff of the SEC in the Morgan Stanley Letter and similar SEC no-action letters, and, in the absence of an exemption therefrom, must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction of the Series B notes, in which case the registration statement must contain the selling security holder information required by Item 507 or Item 508, as applicable, of Regulation S-K of the SEC; and - a broker-dealer that delivers such a prospectus to purchasers in connection with such resales will be subject to certain of the civil liability provisions under the Securities Act and will be bound by the provisions of the registration agreement (including certain indemnification rights and obligations). The undersigned will, upon request, execute and deliver any additional documents deemed by the exchange agent or Leviathan to be necessary or desirable to complete the exchange, assignment and transfer of the Series A notes tendered hereby, including the transfer of such Series A notes on the account books maintained by the book-entry transfer facility. For purposes of the exchange offer, Leviathan shall be deemed to have accepted for exchange validly tendered Series A notes when, as and if Leviathan gives oral or written notice thereof to the exchange agent. Any tendered Series A notes that are not accepted for exchange pursuant to the exchange offer for any reason will be returned, without expense, to the undersigned at the address shown below or at a different address as may be indicated herein under "Special Delivery Instructions" as promptly as practicable after the expiration date. All authority conferred or agreed to be conferred by this Letter of Transmittal shall survive the death, incapacity or dissolution of the undersigned, and every obligation of the undersigned under this Letter of Transmittal shall be binding upon the undersigned's heirs, personal representatives, successors and assigns. The undersigned acknowledges that the acceptance of properly tendered Series A notes by Leviathan pursuant to the procedures described under the caption "The Exchange Offer -- Procedures for Tendering Series A Notes" in the prospectus and in the instructions hereto will constitute a binding agreement between the undersigned and Leviathan upon the terms and subject to the conditions of the exchange offer. Unless otherwise indicated under "Special Issuance Instructions," please issue the Series B notes issued in exchange for the Series A notes accepted for exchange and return any Series A notes not tendered or not exchanged, in the name(s) of the undersigned. Similarly, unless otherwise indicated under "Special Delivery Instructions," please mail or deliver the Series B notes issued in exchange for the Series A notes accepted for exchange and any Series A notes not tendered or not exchanged (and accompanying documents, as appropriate) to the undersigned at the address shown below the undersigned's signature(s).

Signatures on this Letter of Transmittal; Bond Powers and Endorsements; Guarantee of Signatures. If this Letter of Transmittal (or facsimile hereof) is signed by the record holder(s) of the Series A notes tendered hereby, the signature must correspond with the name(s) as written on the face of the Series A notes without alteration, enlargement or any change whatsoever. If this Letter of Transmittal (or facsimile hereof) is signed by a participant in the book-entry transfer facility, the signature must correspond with the name as it appears on the security position listing as the holder of the Series A notes. If this Letter of Transmittal (or facsimile hereof) is signed by the registered holder or holders of Series A notes listed and tendered hereby and the Series B notes issued in exchange therefor are to be issued (or any untendered principal amount of Series A notes is to be reissued) to the registered holder, the said holder need not and should not endorse any tendered Series A notes, nor provide a separate bond power. In any other case, such holder must either properly endorse the Series A notes tendered or transmit a properly completed separate bond power with this Letter of Transmittal, with the signatures on the endorsement or bond power guaranteed by an eligible institution. If this Letter of Transmittal (or facsimile hereof) is signed by a person other than the registered holder or holders of any Series A notes listed, such Series A notes must be endorsed or accompanied by appropriate bond powers, in each case signed as the name of the registered holder or holders appears on the Series A notes. If this Letter of Transmittal (or facsimile hereof) or any Series A notes or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and, unless waived by Leviathan, evidence satisfactory to Leviathan of their authority to act must be submitted with this Letter of Transmittal. Endorsements on Series A notes or signatures on bond powers required by this Instruction 5 must be guaranteed by an eligible institution. No signature guarantee is required if: - this Letter of Transmittal (or facsimile hereof) is signed by the registered holder(s) of the Series A notes tendered herein (or by a participant in the book-entry transfer facility whose name appears on a security position listing as the owner of the tendered Series A notes) and the Series B notes are to be issued directly to such registered holder(s) (or, if signed by a participant in the book-entry transfer facility, deposited to such participant's account at such book-entry transfer facility) and neither the box entitled "Special Delivery Instructions" nor the box entitled "Special Issuance Instructions" has been completed; or - such Series A notes are tendered for the account of an eligible institution. In all other cases, all signatures on this Letter of Transmittal (or facsimile hereof) must be guaranteed by an eligible institution. 6. Special Issuance and Delivery Instructions. Tendering holders should indicate, in the applicable box or boxes, the name and address (or account at the book-entry transfer facility) to which Series B notes or 9 10 substitute Series A notes for principal amounts not tendered or not accepted for exchange are to be issued or sent, if different from the name and address of the person signing this Letter of Transmittal. In the case of issuance in a different name, the taxpayer identification or social security number of the person named must also be indicated. 7. Transfer Taxes. Leviathan will pay all transfer taxes, if any, applicable to the exchange of Series A notes pursuant to the exchange offer. If, however, Series B notes or Series A notes for principal amounts not tendered or accepted for exchange are to be delivered to, or are to be registered or issued in the name of, any person other than the registered holder of the Series A notes tendered hereby, or if tendered Series A notes are registered in the name of any person other than the person signing this Letter of Transmittal, or if a transfer tax is imposed for any reason other than the exchange of Series A notes pursuant to the exchange offer, then the amount of any such transfer taxes (whether imposed on the registered holder or any other persons) will be payable by the tendering holder. If satisfactory evidence of payment of such taxes or exemption therefrom is not submitted with this Letter of Transmittal, the amount of such transfer taxes will be billed directly to such tendering holder. EXCEPT AS PROVIDED IN THIS INSTRUCTION 7, IT WILL NOT BE NECESSARY FOR TRANSFER TAX STAMPS TO BE AFFIXED TO THE SERIES A NOTES LISTED IN THIS LETTER OF TRANSMITTAL. 8. Tax Identification Number. Federal income tax law requires that a holder of any Series A notes that are accepted for exchange must provide Leviathan (as payor) with its correct taxpayer identification number ("TIN"), which, in the case of a holder who is an individual is his or her social security number. If Leviathan is not provided with the correct TIN, the holder may be subject to a $50 penalty imposed by the Internal Revenue Service. (If withholding results in an over-payment of taxes, a refund may be obtained). Certain holders (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. See the enclosed "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" for additional instructions. To prevent backup withholding, each tendering holder must provide such holder's correct TIN by completing the Substitute Form W-9 set forth herein, certifying that the TIN provided is correct (or that such holder is awaiting a TIN), and that: - the holder has not been notified by the Internal Revenue Service that such holder is subject to backup withholding as a result of failure to report all interest or dividends; or - the Internal Revenue Service has notified the holder that such holder is no longer subject to backup withholding. If the Series A notes are registered in more than one name or are not in the name of the actual owner, see the enclosed "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" for information on which TIN to report. Leviathan reserves the right in its sole discretion to take whatever steps are necessary to comply with Leviathan's obligations regarding backup withholding. 9. Validity of Tenders. All questions as to the validity, form, eligibility (including time of receipt), acceptance and withdrawal of tendered Series A notes will be determined by Leviathan in its sole discretion, which determination will be final and binding. Leviathan reserves the absolute right to reject any and all Series A notes not properly tendered or any Series A notes the acceptance of which would, in the opinion of Leviathan or its counsel, be unlawful. Leviathan also reserves the absolute right to waive any conditions of the exchange offer or defects or irregularities in tenders as to particular Series A notes. The interpretation of the terms and conditions by Leviathan of the exchange offer (which includes this Letter of Transmittal and the instructions hereto) shall be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of Series A notes must be cured within such time as Leviathan shall determine. Neither Leviathan, the exchange agent nor any other person shall be under any duty to give notification of defects or irregularities with regard to tenders of Series A notes nor shall any of them incur any liability for failure to give such notification. 10 11 10. Waiver of Conditions. Leviathan reserves the absolute right to waive, in whole or part, any of the conditions to the exchange offer set forth in the prospectus. 11. No Conditional Tender. No alternative, conditional, irregular or contingent tender of Series A notes or transmittal of this Letter of Transmittal will be accepted. 12. Mutilated, Lost, Stolen or Destroyed Series A Notes. Any holder whose Series A notes have been mutilated, lost, stolen or destroyed should contact the exchange agent at the address indicated above for further instructions. 13. Requests for Assistance or Additional Copies. Requests for assistance or for additional copies of the prospectus or this Letter of Transmittal may be directed to the exchange agent at the address or telephone number set forth on the cover page of this Letter of Transmittal. Holders may also contact their broker, dealer, commercial bank, trust company or other nominee for assistance concerning the exchange offer. 14. Withdrawal.
