         4. Representations and Warranties of Trident. Trident represents and
warrants to ILCD as follows:

              (a) Authority. Trident is a limited partnership duly organized,
validly existing and in good standing under the laws of the state of Delaware,
and has all requisite partnership power and authority to carry on its business
as now conducted and as currently proposed to be conducted by it and to enter
into and perform this Agreement. All partnership action on the part of Trident
necessary for the authorization, execution, delivery and performance of all
obligations of Trident under the Agreement has been taken.

              (b) Binding Obligation. Trident has the legal power and authority
to enter into and perform this Agreement and to consummate the transactions
contemplated hereby. This Agreement has been duly and validly executed and
delivered by and on behalf of Trident and constitutes a valid and legally
binding obligation of Trident, enforceable against Trident in accordance with
its terms.

              (c) Title to Shares. Trident is the sole record and beneficial
owner of the Shares, free and clear of all liens or encumbrances of any kind or
nature, any preemptive rights, co-sale rights, rights of first refusal or any
other rights of any kind or nature which limit, condition, or restrict in any
way Trident's right to transfer and sell the Shares.

              (d) Absence of Litigation. There is no litigation or proceeding
pending or, to the best of Trident's knowledge, threatened against Trident that
would have an effect on the validity or performance of this Agreement.

              (e) No Brokers Fees. No person has or will receive from Trident
or, to Trident's knowledge, from any other person, any compensation as a broker,
finder or advisor, or in any other capacity in connection with the sale and
purchase of the Shares or the Interest.

              (f) Investment Intent. Trident understands, acknowledges and
represents, to the extent applicable, that:

                      (i) The Interest has not been registered under the
Securities Act of 1933, as amended (the "Securities Act"), or under any state
securities or blue sky laws, and the transfer of the Interest is intended to be
exempt from registration under the Securities Act based, in part, upon the
representations, warranties and covenants of Trident contained herein.

                      (ii) Neither the United States Securities and Exchange
Commission nor any state securities commission has (i) approved the transfer of
the Interest or passed upon or endorsed the merits of the Interest, or (ii)
confirmed the accuracy of, determined the adequacy of, or reviewed any
documentation regarding ILCD or Louisiana Shelf.

                                       2
<PAGE>

              (iii) It has such knowledge, sophistication and experience in
financial, tax and business matters in general, and investments in securities in
particular, so that it is capable of evaluating the merits and risks of an
investment in the Interest, it has made such investigations in connection
herewith as it has deemed necessary or desirable so as to make an informed
investment decision without relying on ILCD for legal or tax advice related to
this investment, and it has had the opportunity to obtain additional information
as desired in order to evaluate the merits of and the risks inherent in an
investment in the Interest and has received all such information requested and
has had all such questions answered to its satisfaction.

              (iv) The Interest is being purchased in a private transaction
separately negotiated by Trident, for its own account, for investment purposes
only and not with a view to distribution, and it was unaware of, and did not
rely upon, and did not become aware of the offering of the Interest through or
as a result of, any form of general solicitation or general advertising
including, without limitation, any article, notice, advertisement or other
communication published in any newspaper, magazine or similar media, or
broadcast over television or radio, in connection with the offer and sale of the
Interest.

              (v) It is able to bear the economic risks of an investment in the
Interest and its overall commitment to investments that are not readily
marketable is not disproportionate to its net worth.

              (vi) It must bear the substantial economic risks of the investment
in the Interest indefinitely, as the Interest is a "restricted security" as that
term is defined in Regulation D under the Securities Act and may not be sold,
hypothecated or otherwise disposed of unless registered under the Securities Act
and applicable state securities laws or an exemption from such registration is
available. Legends shall be placed on the certificates evidencing the Interest
to the effect that the Interest has not been registered under the Securities Act
or any applicable state securities laws.

              (vi) Any information that the undersigned has heretofore furnished
or furnishes herewith to ILCD is complete and accurate and may be relied upon by
ILCD in determining the availability of an exemption from registration under
federal and state securities laws (including, but not limited to, the Securities
Act) in connection with the purchase of the Interest hereunder.

         5. Representations and Warranties of ILCD. ILCD hereby represents and
warrants to Trident as follows:

              (a) Authority. ILCD is a corporation duly organized, validly
existing and in good standing under the laws of the state of Colorado and has
all requisite corporate power and authority to carry on its business as now
conducted and as currently proposed to be conducted by it and to enter into and
perform this Agreement. All corporate action necessary on the part of ILCD for
the authorization, execution, delivery and performance of all obligations of
ILCD under the Agreement has been taken.

enter into and perform this Agreement and to consummate the transactions
contemplated hereby. This Agreement has been duly and validly executed and
delivered by and on behalf of ILCD and constitutes a valid and legally binding
obligation of ILCD, enforceable against ILCD in accordance with its terms.

other rights of any kind or nature which limit, condition, or restrict in any

              (d) Absence of Litigation. There is no litigation or proceeding
pending or, to the best of ILCD's knowledge, threatened against ILCD that would

the transactions contemplated hereby are confidential and shall not be disclosed
to any person for any reason. Trident understands that certain information
conveyed to it by ILCD in connection with the conversion of the Notes may be
regarded as material non-public information under Regulation FD under the
Securities Act of 1933, as amended. Trident hereby acknowledges that it remains
bound by its prior express agreement to maintain the confidentiality of such
information and to not disclose such information to any person. Trident
understands that Federal law provides severe civil and criminal penalties for
trading in the public market on the basis of material non-public information.

         7. General Release. Trident, for itself and on behalf of its equity
owners, directors, officers, managers, affiliates, successors and assigns, does
hereby fully and irrevocably remise, release and forever discharge ILCD and each
of its directors, officers, shareholders, affiliates, employees, agents,
attorneys, accountants, successors and assigns, of and from any and all manner
of claims, actions, causes of action, grievances, liabilities, obligations,

                                 PROMISSORY NOTE

$350,000                                                Bala Cynwyd, PA
                                                        September ___, 2003

                  FOR VALUE RECEIVED, LSP Exploration, LLC, a Delaware limited
liability company (the "Borrower"), with a principal place of business at One
Belmont Avenue, Suite 417, Bala Cynwyd, PA 19004 hereby promises to pay to the
order of International Travel CD's, Inc., a Colorado corporation (the "Lender"),
at 111 Presidential Boulevard, Suite 158A, Bala Cynwyd, Pennsylvania, 19004, the
principal sum of Three Hundred and Fifty Thousand Dollars (US $350,000) payable
in cash on September 24, 2004 (the "Maturity Date").

                  The entire principal amount together with interest at the rate
of three percent (3%) percent per annum, shall be paid on the Maturity Date.

                  All payments (including prepayments) to be made by the
Borrower hereunder, whether on account of principal, interest or otherwise,
shall be made without set off or counterclaim and shall be made prior on the
Maturity Date thereof to the Lender at the address set forth above, or such
other place as Lender may from time to time designate in writing. If any payment
or action to be made or taken hereunder shall be stated to be or become due on a
day which is not a Business Day, such payment or action shall be made or taken
on the next following Business Day and such extension of time shall be included
in computing interest or fees, if any, in connection with such payment or
action.

         Any failure to repay the principal or interest due hereunder upon the
Maturity Date or any failure to adhere to the terms of this Note shall be
considered an Event of Default. Upon the occurrence of an Event of Default the
entire amount of the indebtedness evidenced by this Note hereby shall be
immediately due and payable. Upon the acceleration of the obligations evidenced
by this Note and failure by the Borrower to pay amounts then due hereunder,
Lender may proceed to protect, exercise and enforce all of its rights and
remedies under this Note and applicable law. The remedies provided in this Note
are cumulative and concurrent, may be pursued in any order, separately,
successively or together, may be exercised as often as occasion therefor may
arise, and shall be in addition to, and not in substitution for, the rights and
remedies which would otherwise be vested in Lender for the recovery of damages,
or otherwise, in the event of a breach of any of the undertakings of the
Borrower hereunder. This Agreement may not be modified, altered or amended,
except by an agreement in writing signed by the Borrower and the Lender. The
Lender may not sell, assign or transfer this Note or any portion hereof.

         This Note shall bind the Borrower and its successors and assigns, and
the benefits hereof shall inure to the benefit of the Lender and its successors
and assigns. All references herein to the "Borrower" and the "Lender" shall be
deemed to apply to the Borrower and the Lender, respectively, and their
respective successors and assigns.

<PAGE>

         Borrower may prepay the loan evidenced by this Note at anytime without
the consent of the Lender.

         This Note and any other documents delivered in connection herewith and
the rights and obligations of the parties hereto and thereto shall for all
purposes be governed by and construed and enforced in accordance with the
internal laws of the Commonwealth of Pennsylvania without giving effect to its
conflicts of law principles.

         IN WITNESS WHEREOF, the undersigned, intending to be legally bound
hereby, has executed this Note as of the date first written above with the
intention that this Note shall constitute a sealed instrument.
