                                    PREAMBLE
                                    --------

October 18, 2003, as amended (the "Employment Agreement");

     WHEREAS, Executive's last day of employment as President and Chief
Operating Officer of the Company pursuant to the Employment Agreement shall be

     WHEREAS, the Parties intend that this Agreement shall govern all issues
related to Executive's employment and separation from the Company;

     WHEREAS, the Company has advised Executive in writing to consult with a

     NOW, THEREFORE, in consideration of the mutual promises and obligations

and include Gexa Corp., a Texas corporation, and all of its predecessors,

individual or official capacities.

2.       Resignation by Executive.

     2.1 Effective on October 19, 2004, Executive shall resign all positions he
holds as an officer or director of the Company and/or its Affiliates, and shall
provide a letter of resignation to the Company in the form attached as Exhibit
1.

     2.2 The Company shall publish the press release attached as Exhibit 2 to
this Agreement, which was reviewed by and agreed to in advance by the Executive.

3.       Termination of the Employment Agreement. The Parties agree that the
Employment Agreement is hereby terminated and of no further force and effect as
of the Resignation Date, and no payments or benefits are due or payable
thereunder, except that paragraphs 7, 8 and 10 (respecting confidential
information, non-solicitation and remedies) of the Employment Agreement shall
survive termination.

4.       Severance Payments to Executive.

     4.1 The Company agrees to continue to pay Executive his base salary as in
effect on the date hereof at a monthly rate of $16,666.67 through December 31,
2004 (the "Severance Period"), on the dates and in the manner the Company
presently pays its other employees. The Executive will be entitled to no bonus
relating to his performance or employment on or before the Resignation Date.

     4.2 During the Severance Period, the Executive shall not continue to
participate under the Company's 401(k) plan.

     4.3 No additional vacation time will accrue during the Severance Period or
thereafter. All accrued unpaid vacation held by the Executive as of the
Resignation Date is hereby forfeited.

     4.4 Except as otherwise provided in Section 5, Executive's participation in
all other employee benefit plan and programs maintained by the Company and/or
its Affiliates shall cease on December 31, 2004, in accordance with the plan's
terms. If Executive timely elects to continue his group medical insurance
coverage in accordance with the Consolidated Omnibus Budget Reconciliation Act
of 1985, as amended ("COBRA"), then Executive shall be responsible for all
premiums to maintain such coverage as required under COBRA under the Company's
plan (to the extent such coverage is available) during and after the Severance
Period.

5.       Stock Options & Restricted Stock.

     5.1 Executive and the Company agree that Executive holds 25,000 shares
("Restricted Stock") of the Company's common stock, par value $.01 ("Common
Stock"), as described on the attached Exhibit 3. As used herein, "Share" shall
mean a share of Common Stock; and "Option Shares" shall mean Shares that are
issued or issuable upon the exercise of the Options. The Restricted Stock and
Options were issued pursuant to the Employment Agreement.


                                       2
<PAGE>

     5.2 The Company agrees that:

     a. all shares of Restricted Stock shown in Exhibit 3 hereto have been and
are fully vested. The Restricted Stock were issued on October 18, 2003. The only
restrictions on the sale or transfer of the Restricted Stock are the
restrictions imposed by the Securities Act of 1933, as amended (the "1933 Act")
and, after October 18, 2004, the Shares of the Restricted Stock may be sold in
compliance with Rule 144 or another available exception from registration under
the 1933 Act, subject to the applicability of any limitations imposed under SEC
Rue 10b-5. The Options covering 350,000 Shares of the Company's Common Stock are
currently vested as to 116,667 of those Shares, and shall vest as to an
additional 116,667 of those shares on October 18, 2004. Under the terms of the
Employment Agreement, the remaining 116,666 of the Options are to vest on
October 18, 2005. However, the parties have agreed to amend the vesting schedule
in the Employment Agreement so that the vesting of the Options as to such
remaining 116,666 Shares will occur only upon a Change of Control if such Change
of Control occurs on or before December 31, 2005; provided, however, if the
Company shall have entered into an agreement or letter of intent with respect to
a Change of Control on or before December 31, 2005, then the vesting date shall
be extended to January 1, 2007. If the Change of Control does not occur on or
before December 31, 2005 (as may be extended as provided in the preceding
sentence), the vesting of the Options as to such remaining 116,666 Shares will
not vest and will not be exercisable. Any vested Options may be exercised, in
whole or in part, on or before April 1, 2007; all of the unexercised Options
then outstanding, vested and unvested, will terminate and expire and be of no
further force and effect after April 2, 2007.

     b. the exercise price of the Option has been and remains $2.25 per share
(the Option Price"). The Options shall be exercised by the delivery of a signed
written notice of exercise to the Company. The notice shall set forth the number
of shares with respect to which the Option is to be exercised. The Option Price
upon exercise of any Option shall be payable to the Company in full either: (i)
in cash or its equivalent, or (ii) by tendering previously acquired shares of
Common Stock having an aggregate Fair Market Value (as defined below) at the
time of exercise equal to the total Option Price (provided that the shares which
are tendered must have been held by the Executive for at least six (6) months
prior to their tender to satisfy the Option Price), or (iii) by withholding
Shares which otherwise would be acquired on exercise having an aggregate Fair
Market Value at the time of exercise equal to the total Option Price, or (iv) by
a combination of (i), (ii), and (iii) above. Any payment in Shares shall be
effected by the surrender of such shares to the Company in good form for
transfer and shall be valued at their Fair Market Value on the date when the
Option is exercised.

     Option Price may also be paid by effecting a "cashless exercise" with a
broker of the Option), subject to applicable securities law restrictions and tax
withholdings. A "cashless exercise" of an Option is a procedure by which a
broker provides the funds to the Executive to effect an Option exercise. At the
direction of the Executive, the broker will either (i) sell all of the Shares
received when the Option is exercised and pay the Executive the proceeds of the
sale (minus the Option Price, withholding taxes and any fees due to the broker)
or (ii) sell enough of the Shares received upon exercise of the Option to cover
the Option Price, withholding taxes and any fees due the broker and deliver to
the Executive (either directly or through the Company) a stock certificate for
the remaining Shares. In no event will the Company allow the Option Price to be
paid with a form of consideration, including a loan or a "cashless exercise," if
such form of consideration would violate the Sarbanes-Oxley Act of 2002 as
determined by the Company in its good faith discretion.

                                       3
<PAGE>

     If the Company has allowed or allows any of its executives to exercise
their options other than through the payment of cash, it shall permit Executive
to avail himself of such alternative methods for effecting the exercise of his
Options.

     As soon as practicable after receipt of a written notification of exercise
and full payment, the Company shall deliver, or cause to be delivered, to or on
behalf of the Executive, in the name of the Executive or other appropriate
recipient, share certificates for the number of Shares purchased under the
Option. Such delivery shall be effected for all purposes when the Company or a
stock transfer agent of the Company shall have deposited such certificates in
the United States mail, addressed to Executive or other appropriate recipient.

     The term Fair Market Value of one Share of Common Stock of the Company on
the date in question shall mean (i) the closing sales price as reported on the
consolidated reporting system for the securities exchange(s) on which shares are
then listed or admitted to trading (as reported in the Wall Street Journal or
other reputable source), or (ii) if not so reported, the average of the closing
bid and asked prices for a share as quoted on the Nasdaq Stock Market, Inc.
("NASDAQ"), or (iii) if not quoted on NASDAQ, the average of the closing bid and
asked prices for a share as quoted by the National Quotation Bureau's "Pink
Sheets" or the National Association of Securities Dealers' OTC Bulletin Board
System. If there was no public trade of common stock on the date in question,
Fair Market Value shall be determined by reference to the last preceding date on
which such a trade was so reported.

     If the Company is not a publicly held corporation at the time a
determination of the Fair Market Value of the common stock is required to be
made hereunder, the determination of Fair Market Value shall be made by the
Board of Directors of the Company in its discretion exercised in good faith and
in a manner consistent with other similar determinations. In this respect, the
Board may rely on such financial data, valuations, experts, and other sources,
in its discretion, as it deems advisable under the circumstances.

     c. A "Change of Control" shall be deemed to have occurred upon any of the
following events:

     (i) any "person" (as defined in Section 3(a)(9) of the Securities Exchange
Act of 1934, as amended, and as modified in Section 13(d) and 14(d) of the
Securities Exchange Act of 1934, as amended) other than an underwriter
temporarily holding securities pursuant to an offering of such securities (a
"Person"), becomes as a result of a transaction or event after the date hereof
the "beneficial owner" (as defined in Rule 13d-3 of the Exchange Act), directly
or indirectly, of securities of the Company representing more than 50% of the
shares of voting stock of the Company then outstanding;

                                       4
<PAGE>

     (ii) the consummation of any merger, organization, business combination or
consolidation of the Company or one of its subsidiaries with or into any other
entity, other than a merger, reorganization, business combination or
consolidation which would result in the holders of the voting securities of the
Company outstanding immediately prior thereto holding securities which represent
immediately after such merger, reorganization, business combination or
consolidation more than 50% of the combined voting power of the voting
securities of the Company or the surviving company or the parent of such
surviving company;

     (iii) the consummation of a sale or disposition by the Company of all or
substantially all of the Company's assets, other than a sale or disposition if
the holders of the voting securities of the Company outstanding immediately
prior thereto hold securities immediately thereafter which represent more than
50% of the combined voting power of the voting securities of the acquiror, or
parent of the acquiror, of such assets;

     (iv) the stockholders of the Company approve a plan of complete liquidation
or dissolution of the Company;

     (v) individuals who, as of the date hereof, constitute the Board (the
"Incumbent Board") cease for any reason to constitute at least a majority of the
Board; provided, however, that any individual becoming a director subsequent to
the date hereof whose election by the Board, was approved by a vote of at least
a majority of the directors then comprising the Incumbent Board shall be
considered as though such individual were a member of the Incumbent Board, but
excluding, for this purpose, any such individual whose initial assumption of
office occurs as a result of an election contest with respect to the election or
removal of directors or other solicitation of proxies or consents by or on
behalf of a person other than the Board; or

     (vi) the occurrence of any other event that the Board of Directors of the
Company determines constitutes a Change in Control with respect to options or
other issuances under the Company's 2004 Incentive Plan and/or the taking of any
action by the Board of Directors (or committee thereof) after the date hereof
that has the effect of accelerating any vesting requirements with respect to a
majority of the incentive or other awards issued to the executive officers of
the Company.

     d. except as set forth in this Section 5, the terms of the Options remain
in full force and effect and subject to the terms of the agreements by which
such Options were awarded.

     e. The issuance or transfer of the Shares shall be subject to all
applicable federal, state and local laws and regulations and applicable rules
and regulations of any exchanges on which such securities are traded or listed
and no issuance or transfer shall be made in violation of any of the foregoing.

     f. The Company shall have the right to deduct from any payment made to
Executive, or to otherwise require payment by Executive of, prior to the
issuance or delivery of any Shares of the Company's Common Stock, any federal,
state or local taxes required by law to be withheld by the Company; provided,
however, that if the Company has allowed or allows any of its executives to
satisfy such withholding obligations in a manner other than payment in cash, it
shall permit Executive to avail himself of such alternative methods for
satisfying such withholding.

                                       5
<PAGE>

     g. The Option Shares are registered under an S-8 Registration Statement
(No. 333-116722) filed with the Securities and Exchange Commission on June 22,
2004. The Company agrees to keep that Registration Statement effective during
the term of the Options. The Executive agrees that he will not exercise the
Options or sell any of the Option Shares or the Restricted Stock until April 1,
2005, in the Nasdaq market; provided, that the Executive will be permitted to
exercise the Options and sell the Option Shares and the Restricted Stock in
connection with and pursuant to any Change of Control occurring before April 1,
2005. After April 1, 2005, the Executive will not be subject to any restrictions
under the Agreement regarding the exercise of the Options, in accordance with
the terms thereof as stated herein, or the sale of the Option Shares.

9.       Confidentiality.

     9.1 Both Parties shall keep strictly confidential all the terms and
conditions, including amounts, in the Agreement and shall not disclose them to
any person other than legal and/or financial advisors, government officials who
seek such information in the course of their official duties, individuals at the
Company responsible for implementing the Agreement, or Executive's spouse,
unless compelled to do so by law or regulation, or business necessity (including
Securities Exchange Commission or tax reporting obligations). Nothing in this
Section is intended to prevent Executive from disclosing the fact that he was
employed by the Company or from describing his employment duties.

10.      Litigation Support.

     10.1 In the event and for so long as the Company is actively contesting or
defending against any action, suit, proceeding, hearing, investigation, charge,
complaint, claim, or demand brought against (a) the Company and/or its
Affiliates or (b) the Executive in his capacity of employee, director or officer
of the Company in connection with any fact, situation, circumstance, status,
condition, activity practice, plan, occurrence, event, incident, action, failure
to act, or transaction involving the Company, then Executive will reasonably
cooperate with the Company or its counsel in the contest or defense, and provide
such testimony and access to his books and records as shall be reasonably
necessary in connection with the contest or defense, all at the sole cost and
expense of the Company. The Executive further agrees to not provide assistance
of any kind, other than as required by law, to any party to assist in pursuing
any currently pending or threatened claim, litigation, arbitration, mediation,
administrative hearing or other legal proceedings against the Company.

     10.2 Notwithstanding any alleged or actual intentional, grossly negligent,
negligent, or other wrongdoing of Executive, the Company shall indemnify, defend
and hold harmless the Executive, against all costs or expenses (including
reasonable attorneys' fees), judgments, fines, losses, claims, damages or
liabilities (collectively, "Costs") incurred in connection with any claim,
action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, arising out of actions or omissions by the
Executive in any of his capacities as employee, agent, officer or director of
the Company or one or more of its Affiliates, or taken by him at the request of
the Company or one of the Affiliates of the Company to the fullest extent that
the Company (or an Affiliate, as the case may be) is permitted to indemnify its
directors and officers under the laws of its jurisdiction of incorporation, and
its certificate of incorporation and bylaws (or comparable organizational
documents) as in effect on the date hereof (and the Company shall also advance
expenses as incurred to the fullest extent permitted under applicable law).
Without limiting the foregoing, the Company shall honor all rights to
indemnification and exculpation from liabilities for acts or omissions occurring
at or prior to the date hereof now existing in favor of current or former
employees, agents, directors or officers of the Company as provided in its
organizational documents and indemnification agreements or arrangements
heretofore entered into by the Company in accordance with their terms. The
Company shall continue to provide directors' and officers' liability insurance
with respect to claims against the Executive arising from facts, events, acts or
omissions which occurred at or prior to the date hereof, to the same extent and
with the same coverage and amounts, and terms and conditions, as that coverage
provided by the Company from time to time for its executives or directors. In
the event that the Company or any of its respective successors or assigns
undergoes a Change of Control, then, and in each such case, proper provision
will be made so that the successors and assigns of the Company, will assume the
obligations set forth in this Section 10.2.

Association then in effect, as amended by this Agreement, and judgment on the
award rendered by the arbitrator may be entered in any court of competent
jurisdiction. The parties agree that the arbitrator shall have no power or
authority to make awards or issue orders of any kind except as expressly
permitted by this Agreement. The arbitrator's decision shall follow the plain
meaning of the relevant documents, apply Texas law, and shall be final and
binding. The location of such arbitration in Houston, Texas, shall be selected
by the Company in its sole and absolute discretion. All costs and expenses,
including attorneys' fees, relating to the resolution of any such dispute shall
be borne by the party incurring such costs and expenses.

     13.2 Notwithstanding the preceding paragraph, the Parties acknowledge that
either of them may seek emergency or temporary or permanent injunctive relief or
a restraining order, including but not limited to such emergency relief or
temporary or permanent injunctive relief or a restraining order to enforce

relief, in any court of competent jurisdiction. All other disputes, claims and
remedies shall be settled by arbitration in accordance with Section 13.1.

                                       8
<PAGE>

14. No Defamatory Statements. Executive and the Company agree that neither
will make statements about the other at any time that are slanderous, libelous
or defamatory.

15.      Miscellaneous.

     15.1 The Parties acknowledge that this Agreement is the result of a
compromise and shall never be construed as, or said by either of them to be, an
admission by the other of any liability, wrongdoing, or responsibility. The
Parties expressly disclaim any such liability, wrongdoing, fault, or
responsibility.

     15.2 This Agreement, the surviving paragraphs of the Employment Agreement
and agreements and documents related to Options, Restricted Stock and other
benefit plans constitute the entire agreement between the Parties. This
Agreement may be executed in identical counterparts, each of which shall
constitute an original and all of which shall constitute one and the same
agreement.

     15.3 The Parties warrant that no representations have been made other than
those contained in the written provisions of this Agreement, and that they do
not rely on any representations not stated in this Agreement.

     15.4 The Parties further warrant that they or their undersigned
representatives are legally competent and fully authorized to execute and
deliver this Agreement.

     15.5 The Parties confirm they have had the opportunity to have this
Agreement explained to them by attorneys of their choice, and that they execute
this Agreement freely, knowingly and voluntarily. The Company is relying on its
own judgment and on the advice of its attorneys and not upon any recommendation
of Executive or his agents, attorneys or other representatives. Likewise,
Executive is relying on his own judgment and on the advice of his attorneys, and
not upon any recommendation of the Company or its directors, officers,
employees, agents, attorneys or other representatives. By voluntarily executing
this Agreement, both Parties confirm their competence to understand and do
hereby accept the terms of this Agreement as resolving fully all differences,
disputes and claims that may exist within the scope of this Agreement.

     15.6 Executive represents that neither he nor any person, organization or
other entity on his behalf has filed or authorized the filing of and will file
or participate in, at any time, any complaints, charges or lawsuits against the
Company and/or its Affiliates with any federal, state or local court,
governmental agency, or administrative agency, and that if, unbeknownst to
Executive, any such complaint has been or is filed on his behalf, he will use
his best efforts to cause it to immediately be withdrawn and dismissed with
prejudice with respect to the subjects described in Section 7 of this Agreement.

     15.7 The Company represents that it has not filed or authorized and will
not file or participate in, at any time, the filing of any complaints, charges
or lawsuits against Executive with any federal, state or local court,
governmental agency, or administrative agency, and that if, unbeknownst to the
Company, any such complaint has been filed on its behalf, it will use his best
efforts to cause it to immediately be withdrawn and dismissed with prejudice
with respect to the Subject described in Section 8 of this Agreement.

     15.8 This Agreement may not be modified or amended except by a writing
signed by all Parties. No waiver of this Agreement or of any of the promises,
obligations, terms, or conditions contained in it shall be valid unless it is in
writing signed by the Party against whom the waiver is to be enforced.

     15.9 If any part or any provision of this Agreement shall be finally
determined to be invalid or unenforceable under applicable law by a court of
competent jurisdiction, that part shall be ineffective to the extent of such
invalidity or unenforceability only, without in any way affecting the remaining
parts of said provision or the remaining provisions of the Agreement.

     15.10 The Parties have cooperated in the preparation of this Agreement.
Hence, the Agreement shall not be interpreted or construed against or in favor
of any Party by virtue of the identity, interest, or affiliation of its
preparer.

     15.11 This Agreement is made and shall be enforced pursuant to the laws of
the State of Texas, without regard to its law governing conflicts of law. All
performance required by the terms of this Agreement shall take place in Harris
County, Texas.
