Article 3 Purchase Contracts

In order to obtain supplies of electric power, Gexa has and may enter into Purchase Contracts with TXUPM subject to the following terms and conditions:

3.1   To
provide electric power and capacity needed by Gexa to serve its purchasers, TXUPM and Gexa have entered into the Master Power Purchase and Sale Agreement, and Gexa
has heretofore entered into certain Purchase Contracts with Third-Party Sellers ("Third-Party Purchase Contracts"). Subject to the last sentence of this Section 3.1, effective on the Effective
Date, Gexa shall assign to TXUPM all Third-Party Purchase Contracts entered into by Gexa prior to the date of this Agreement (the "Assigned Contracts"). Such assignment shall be for a term ending upon
the earlier of the termination of the respective Purchase Contract or the termination date of this Agreement. All electric energy and capacity, purchased by TXUPM under the Assigned Contracts shall be
resold to Gexa under the Master Power Purchase and Sale Agreement. To the extent any existing Third-Party Purchase Contract cannot be assigned because of restrictions in such contract or lack of
required consent by the seller thereunder, Gexa may continue to perform its obligations thereunder, and TXUPM shall incur no liability or responsibility with respect to such contract unless the
Parties expressly agree otherwise in writing. Notwithstanding provisions of this Section 3.1 to the contrary, TXUPM shall not be obligated to accept assignment of any Third-Party Purchase
Contract unless the seller under such contract meets the credit and other requirements of TXUPM. In the event TXUPM declines to accept assignment of a Third-Party Purchase Contract, Gexa may continue
to perform its obligations thereunder, and TXUPM shall have no obligation or liability with respect to such contract or purchases thereunder.

3.2   In
the event Gexa desires that TXUPM enter into a contract for the purchase of electric power for resale to Gexa under the Master Power Purchase and Sale Agreement after
the effective date of this Agreement, Gexa shall provide to TXUPM the name of such Third-Party Seller, the quantity of energy and capacity which Gexa desires TXUPM to purchase, pricing information and
such other information as may be reasonably required by TXUPM to evaluate the proposal and the seller's ability to perform. TXUPM shall investigate the creditworthiness of each such Third-Party Seller
and shall notify Gexa in writing of those Third-Party Sellers that satisfy TXUPM's credit and other requirements and which TXUPM is otherwise agreeable to having serve as a supplier (the "Approved
Third-Party Sellers") and those with which TXUPM will not enter into a Third-Party Purchase Contract (the "Unapproved Third-Party Sellers"). TXUPM shall have the right to change its requirements at
any time, and such right shall be exercisable by TXUPM in its sole discretion and without prior notice to Gexa.

3.3   TXUPM
shall use reasonable efforts to notify Gexa of the Approved or Unapproved status of any Third-Party Seller within five (5) Business Days of Gexa first
providing the name of such Third-Party Seller and relevant information regarding the proposed transaction to TXUPM; provided, however, that failure of TXUPM to notify Gexa within such period shall not
constitute or be construed as a designation of such Third-Party Seller as an approved Third-Party Seller.

3.4   In
the case of any Approved Third Party Seller, TXUPM shall agree to purchase Gexa's desired quantities of` electric power and capacity and resell the same to Gexa, both
under terms and conditions satisfactory and approved in advance by the Parties, with such sale to Gexa being in the form of a written confirmation (the "Matching Confirmation") under the Master Power
Purchase and Sale Agreement. In the event any Approved Third Party Seller defaults under a contract with TXUPM that results in declaration of all early termination by TXUPM, TXUPM may upon written
notice to Gexa terminate the Matching Confirmation and the transaction thereunder.

3.5   If
TXUPM fails to approve any Third-Party Seller proposed by Gexa, Gexa may request TXUPM's consent to enter into a contract with such Unapproved Third-Party Seller for
the purchase of` such electric power directly from such seller. TXUPM shall advise Gexa within ten (10) days of receipt of request whether TXUPM, in its sole discretion, approves such purchase
by Gexa. If Gexa at any time enters into a Purchase Contract with an Unapproved Third-Party Seller without the prior written consent of TXUPM, such occurrence shall be deemed to be an Event of Default
under this Agreement.

3.6   If
Gexa, with the consent of TXUPM, enters into a Purchase Contract with an Unapproved Third-Party Seller, Gexa shall use the form of agreement depicted in Exhibit 2. TXUPM shall have no
responsibility or liability with respect to such contract or any purchases thereunder, and Gexa shall bear all
risks associated with any such contract, unless otherwise agreed in writing between the Parties hereto. If Gexa and the Unapproved Third-Party Seller desire to add special provisions to Exhibit 2or otherwise enter into a contract form that is not substantially similar to Exhibit 2, then TXUPM must approve such contract form before Gexa may execute same. If Gexa executes a Purchase Contract
form that has not been
previously approved by TXUPM, such occurrence shall be deemed to be an Event of Default.

3.7   Gexa
shall provide TXUPM with a copy of each executed Third-Party Purchase Contract, including any schedules, exhibits, or written amendments thereto, at least
forty-eight (48) hours prior to the energy delivery date, and within forty-eight (48) hours of execution thereof.

3.8   Unless
Gexa has obtained the prior written approval of TXUPM, the Monthly Purchase Obligations incurred relating to any one (1) calendar month shall not exceed
the quantity (expressed in MWh) set forth onExhibit 5, attached hereto and made a part hereof (the "Monthly Purchase Limit"), and the term of
any such contract shall not extend beyond the scheduled expiration date of this Agreement. If, at any time, Gexa exceeds the then current Monthly Purchase Limit without TXUPM's prior written approval,
such occurrence shall be an Event of Default; provided, however, that TXUPM may, in its sole discretion, waive its rights that arise from any such Event of Default. The Monthly Purchase Limit shall be
reviewed from time-to-time by TXUPM. TXUPM may, in its sole and absolute discretion, increase or decrease the Monthly Purchase Limit; provided, however, that no such increase
or decrease shall be effective unless it is evidenced by written notice from TXUPM to Gexa, and in the event of a decrease to the Monthly Purchase Limit, Gexa must be notified at least 30 days
in advance of the effective date of such decrease. In no event shall the Monthly Purchase Limit be decreased below Gexa's existing aggregate firm purchase or sale obligations for any month. No later
than five (5) Business Days after any change in the Monthly Purchase Limit. TXUPM shall prepare and provide to Gexa a revisedExhibit 5showing the new Monthly Purchase Limit, all prior Monthly Purchase Limits in effect and the dates which such Monthly Purchase Limits were in effect, which new Exhibit 5shall supercede and replace
all priorExhibits 5and shall be a part of this Agreement.

conditions:

4.1   With
respect to Sale Contracts between Gexa and its Customers:

4.2   With
respect to Sale Contracts between Gexa and Third-Party Purchasers:



6

---







4.3   Gexa
agrees that it shall use reasonable efforts to ensure at all times that its Purchase Obligations reasonably balance with its Sale Obligations, each expressed in
MWh, so that it will not have excess or insufficient Purchase Obligations or Sale Obligations as measured against its Sale Obligations or Purchase Obligations, respectively. Gexa further agrees to
enter into such financial or physical agreements as may be necessary to minimize its exposure to movements in market prices of electricity, consistent with prudent business management.

Article 5 Lockbox Agreement and Lockbox Account

and Gexa have executed or will execute one or more agreements as necessary to establish a Lockbox account at a mutually agreeable bank (the "Lockbox Agreement"). A
copy of the Lockbox & Depositary account Requirements are attached hereto asExhibit 6. Such Lockbox Agreement shall be incorporated by
reference in, and made part of, this Agreement. In the event the Lockbox agreement is modified or amended from time to time, such Lockbox Agreement, as modified or amended, shall for all purposes be
deemed to be the Lockbox Agreement referred to herein. Pursuant to the terms of the Lockbox Agreement, the Parties have or will establish a demand deposit account (the "Lockbox Account") with JPMorgan
Chase Bank (the "Bank") for the deposit of funds received by Gexa pursuant to Sale Contracts and for the disbursement of such funds to Gexa and to TXUPM as described in Section 5.5below. The
Parties agree that the execution of the Lockbox Agreement and the establishment of the Lockbox Account shall be conditions
precedent to the effectiveness of this Agreement.

5.2   All
references in this Agreement to the "Lockbox Account" shall be deemed to be references to the account established pursuant to the Lockbox Agreement, irrespective of
any differences in the terminology between this Agreement and the Lockbox Agreement. As collateral security for Gexa's obligations to TXUPM under this Agreement, Gexa hereby grants to TXUPM a present
and continuing security interest in (a) the Lockbox and the Lockbox Account, (b) all contract rights and privileges in respect of the Lockbox or the Lockbox Account, and (c) all
cash, checks, money orders and other items of value of Gexa now or hereafter paid, deposited, credited, held (whether for collection, provisionally or otherwise) or otherwise in the possession or
under the control of, or in transit to, Bank or any agent, bailee or custodian thereof, and all proceeds of the foregoing, and the parties agree to give notice to the Bank in accordance with the
Uniform Commercial Code of TXUPM's security interest in such collateral.

7

---



5.3   The
Lockbox Account shall be maintained during the entire term of this Agreement, and thereafter until all contracts entered into pursuant hereto shall have been
settled. Notwithstanding anything to the contrary in any other agreement between the Parties, Gexa shall be responsible for all fees and service charges relating to the Lockbox Account; none of which
shall be debited against the Lockbox Account.

5.4   As
stated inSections 4.1(c) and 4.2(c),all Customers must be instructed that all payments due to Gexa thereunder must
be deposited into the Lockbox Account.

5.5   Disbursements
from the Lockbox Account shall be made pursuant to the following:



5.6   In
the event interest accrues to the amounts held in the Lockbox Account, Gexa shall be entitled to such interest, subject to any unsatisfied payment obligations under
Section 5.5 above, and TXUPM agrees to authorize disbursements of such accrued interest to Gexa from time to time upon request by Gexa.

5.7   Neither
Party shall communicate with the Bank at which the Lockbox Account has been established regarding making any modifications to the Lockbox Account or the Lockbox
Agreement without the prior written consent of the other Party. This provision shall survive the termination of this Agreement until all payments referenced inSections 5.5(b)
and (c)have been fully and finally paid. Failure to adhere to this provision shall be deemed to be an Event of Default.

5.8   Gexa
shall be responsible for all volumetric and financial accounting with respect to the Sale Contracts entered into pursuant to this Agreement. Within ten
(10) days of the end of each calendar month during the term of this Agreement, Gexa shall deliver to TXUPM an accounting setting forth the beginning and ending balances in the Lockbox Account,
together with a description (including amount) of each transaction conducted in connection with this Agreement for the period referenced. Upon TXUPM's request, Gexa shall provide supporting

any such payment deferral shall be in the sole discretion of TXUPM. In the event that TXUPM makes such a deferral at the request of Gexa, Gexa shall pay TXUPM the entire amount of the deferred

Exhibit 4  Approved Description and letter for Relationship Between Gexa and TXUPM

TO
WHOM IT MAY CONCERN:

TXU
Portfolio Management Company LP ("TXUPM") and Gexa Corporation ("Gexa") have entered into an Energy Marketing Support Agreement effective April 8, 2003, and continuing for an initial term
of five (5) years, regarding certain electric power marketing activities of Gexa. This agreement provides that TXUPM will provide various types of support to Gexa to facilitate Gexa's purchases
of electric power and transmission capacity from third parties. The procedure envisioned by such Agreement is for the supplier to enter into contracts with TXUPM for the sale of supplies to TXUPM,
which will be resold to Gexa. TXUPM will be responsible to the supplier for all obligations in connection with such sale and receipt of electric energy and capacity. Because TXUPM will be supporting
Gexa's business in multiple respects, this should satisfy your company's credit requirements. If you have any questions between the relationship between Gexa and TXUPM, please call Bob Almond at TXUPM
at (214) 875-9365.

any provision of any Loan Document, nor Lender's failure to exercise, nor any delay in exercising, any right, power or privilege hereunder, shall operate as a waiver thereof or waive, affect or
diminish any right of Lender thereafter to demand strict compliance and performance therewith. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or
future exercise thereof or the exercise of any other right, power or privilege. Any suspension or waiver of a Default or other provision under the Loan Documents shall not suspend, waive or affect any
other Default or other provision under any Loan Document, and shall not be construed as a bar to any right or remedy that Lender would otherwise have had on any future occasion. None of the
undertakings, indemnities, agreements, warranties, covenants and representations of Borrower or any other Credit Party to Lender contained in any Loan Document and no Default by Borrower or any other
Credit Party under any Loan Document shall be deemed to have been suspended or waived by Lender, unless such waiver or suspension is by an instrument in writing signed by an officer or other
authorized employee of Lender and directed to Borrower specifying such suspension or waiver (and then such waiver shall be effective only to the extent therein expressly set forth), and Lender shall
not, by any act (other than execution of a formal written waiver), delay, omission or otherwise, be deemed to have waived any of its rights or remedies hereunder.

4.4Severability: Section Titles. Wherever possible, each provision of the Loan Documents shall be interpreted in such manner
as to be effective and valid under applicable law, but if any provision of any Loan Document shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of such Loan Document. Except as otherwise expressly provided for in the Loan
Documents, no termination or cancellation (regardless of cause or procedure) of any financing arrangement under the Loan Documents shall in any way affect or impair the Obligations, duties, covenants,
representations and warranties, indemnities, and liabilities of Borrower or any other Credit Party or the rights of Lender relating to any unpaid Obligation. (due or not due, liquidated, contingent or
unliquidated), or any transaction or event occurring prior to such termination, or any transaction or event, the performance of which is not required until after the termination of the Loan Agreement,
all of which shall not terminate or expire, but rather shall survive such termination or cancellation and shall continue in full force and effect until the Termination Date; provided, that all
indemnity obligations of the Credit Parties under the Loan Documents shall survive the Termination Date. The Section titles contained in any Loan Document are and shall be without substantive meaning
or content of any kind whatsoever and are not a part of the agreement between the parties hereto.

Borrower's or such other Credit Party's Board of Directors, and Lender shall be entitled to assume the authority of each signature and authority of the person whose signature it is or appears to be
unless the person acting in reliance thereon shall have actual knowledge to the contrary.

RE:    Energy
Marketing Support Agreement dated April 8, 2003 (the "Support Agreement") between TXU Portfolio Management Company LP ("TXUPM") and Gexa Corporation, d/b/a Gexa Energy
Corporation ("Gexa")

Dear
Neil:

The
purpose of this letter agreement is to clarify the mutual understanding of Gexa and TXUPM regarding the interpretation of Section 4.3 is the Support Agreement regarding Gexa's obligation as
of the date hereof to balance its sales obligations with its purchase obligations. For purposes of said Section 4.3, Gexa and TXUPM agree that with respect to residential customer contracts and
other contracts that are subject to consumer protection rules such that this term is of a month to month nature, that such contracts shall have an assumed term of six months. Except for the use of the
assumed term stated in the prior sentence, Gexa shall ensure that its purchases and sales quantities are in balance using commercially reasonable estimates and business practices.

If
at any time TXUPM determines in its sole discretion that then current market conditions or other factors indicate the interpretation set forth above is no longer appropriate or satisfactory, TXUPM
may terminate the understanding set forth in this letter upon written notice to Gexa, provided that any quantities theretofore contracted for by Gexa in accordance with this letter agreement shall not
be deemed to be a violation of Section 4.3 of the Support Agreement. Upon termination of this letter by TXUPM, Gexa and TXUPM agree to reasonably negotiate to determine another mutually
agreeable interpretation of Section 4.3.

In
the event of a conflict between the Support Agreement and this letter, this letter shall control. Except as may be modified herein, the Support Agreement shall continue in full force and effect in
accordance with its terms. If you are in agreement with the foregoing, please so signify by signing and returning one copy of this letter to the undersigned.

|Sincerely,
/s/JEFF SHORTER |  |  | Agreed,
