Title:



                            NATURAL GAS SYSTEMS, INC.
                                2004 STOCK PLAN:
                      STOCK GRANT AGREEMENT (FOR SERVICES)


SECTION 1. ACQUISITION OF SHARES.

            (a) Transfer. On the terms and conditions set forth in the Summary
of Stock Grant and this Agreement, the Company agrees to transfer to the
Transferee the number of Shares set forth in the Summary of Stock Grant. The
transfer shall occur at the offices of the Company on the date of transfer set
forth in the Summary of Stock Grant or at such other place and time as the
parties may agree.

            (b) Consideration. The Transferee and the Company agree that the
Transferred Shares are being issued to the Transferee as consideration for a
portion of the services performed by the Transferee for the Company. The value
of such portion is agreed to be not less than 100% of the Fair Market Value of
the Transferred Shares.

            (c) Stock Plan and Defined Terms. The transfer of the Transferred
Shares is subject to the Plan, a copy of which the Transferee acknowledges
having received. The provisions of the Plan are incorporated into this Agreement
by this reference. Capitalized terms are defined in Section 12 of this
Agreement.

SECTION 2. FORFEITURE CONDITION.

            (a) Scope of Forfeiture Condition. All Transferred Shares initially
shall be Restricted Shares and shall be subject to forfeiture to the Company.
The Transferee shall not transfer, assign, encumber or otherwise dispose of any
Restricted Shares without the Company's written consent, except as provided in
the following sentence. The Transferee may transfer Restricted Shares to one or
more members of the Transferee's Immediate Family or to a trust established by
the Transferee for the benefit of the Transferee and/or one or more members of



the Transferee's Immediate Family, provided in either case that the Transferee
agrees in writing on a form prescribed by the Company to be bound by all
provisions of this Agreement. If the Transferee transfers any Restricted Shares,
then this Agreement shall apply to the Subsequent Transferee to the same extent
as to the Transferee.

            (b) Vesting. The Forfeiture Condition shall lapse and the Restricted
Shares shall become vested in accordance with the vesting schedule set forth in
the Summary of Stock Grant. The Company may, at its sole discretion, accelerate
the vesting and waive the Forfeiture Condition, at any time.

            (c) Execution of Forfeiture. The Forfeiture Condition shall be
applicable only if the Transferee's Service terminates for Cause, including
(without limitation) death or disability of John Liviakis, before all Restricted
Shares have become vested. In the event that the Transferee's Service terminates
for Cause, the certificate(s) representing any remaining Restricted Shares shall
be delivered to the Company properly endorsed for transfer. The Company shall
make no payment for Restricted Shares that are forfeited.

            (d) Additional Shares or Substituted Securities. In the event of the
declaration of a stock dividend, the declaration of an extraordinary dividend
payable in a form other than stock, a spin-off, a stock split, an adjustment in
conversion ratio, a recapitalization or a similar transaction affecting the
Company's outstanding securities without receipt of consideration, any new,
substituted or additional securities or other property (including money paid
other than as an ordinary cash dividend) which are by reason of such transaction
distributed with respect to any Restricted Shares or into which such Restricted
Shares thereby become convertible shall immediately be subject to the Forfeiture
Condition. Appropriate adjustments to reflect the distribution of such
securities or property shall be made to the number and/or class of the
Restricted Shares.



            (e) Termination of Rights as Stockholder. If Restricted Shares are
forfeited in accordance with this Section 2, then the person who is to forfeit
such Restricted Shares shall no longer have any rights as a holder of such
Restricted Shares. Such Restricted Shares shall be deemed to have been forfeited
in accordance with the applicable provisions hereof, whether or not the
certificate(s) therefor have been delivered as required by this Agreement.

            (f) Escrow. Upon issuance, the certificates for Restricted Shares
shall be deposited in escrow with the Company to be held in accordance with the
provisions of this Agreement. Any new, substituted or additional securities or
other property described in Subsection (d) above shall immediately be delivered
to the Company to be held in escrow, but only to the extent the Transferred
Shares are at the time Restricted Shares. All regular cash dividends on
Restricted Shares (or other securities at the time held in escrow) shall be paid
directly to the Transferee and shall not be held in escrow. Restricted Shares,
together with any other assets or securities held in escrow hereunder, shall be
(i) surrendered to the Company for forfeiture and cancellation in the event that
the Forfeiture Condition applies or (ii) released to the Transferee upon the
Transferee's request to the extent the Transferred Shares are no longer
Restricted Shares (but not more frequently than once every six months). In any
event, all Transferred Shares that have vested (and any other vested assets and
securities attributable thereto) shall be released within 60 days after the
earlier of the termination of the Transferee's Service.

SECTION 3. OTHER RESTRICTIONS ON TRANSFER.

            (a) Transferee Representations. In connection with the issuance and
acquisition of Shares under this Agreement, the Transferee hereby represents and
warrants to the Company as follows:

            (i) The Transferee is acquiring and will hold the Transferred Shares
      for investment for his or her account only and not with a view to, or for
      resale in connection with, any "distribution" thereof within the meaning
      of the Securities Act.



            (ii) The Transferee understands that the Transferred Shares have not
      been registered under the Securities Act by reason of a specific exemption
      therefrom and that the Transferred Shares must be held indefinitely,
      unless they are subsequently registered under the Securities Act or the
      Transferee obtains an opinion of counsel, in form and substance
      satisfactory to the Company and its counsel, that such registration is not
      required. The Transferee further acknowledges and understands that the
      Company is under no obligation to register the Transferred Shares.

            (iii) The Transferee is aware of the adoption of Rule 144 by the
      Securities and Exchange Commission under the Securities Act, which permits
      limited public resales of securities acquired in a non-public offering,
      subject to the satisfaction of certain conditions, including (without
      limitation) the availability of certain current public information about
      the issuer, the resale occurring only after the holding period required by
      Rule 144 has been satisfied, the sale occurring through an unsolicited
      "broker's transaction," and the amount of securities being sold during any
      three-month period not exceeding specified limitations. The Transferee
      acknowledges and understands that the conditions for resale set forth in
      Rule 144 have not been satisfied and that the Company has no plans to
      satisfy these conditions in the foreseeable future.

            (iv) The Transferee will not sell, transfer or otherwise dispose of
      the Transferred Shares in violation of the Securities Act, the Securities
      Exchange Act of 1934, or the rules promulgated thereunder, including Rule
      144 under the Securities Act. The Transferee agrees that he or she will
      not dispose of the Transferred Shares unless and until he or she has
      complied with all requirements of this Agreement applicable to the



      disposition of Transferred Shares and he or she has provided the Company
      with written assurances, in substance and form satisfactory to the
      Company, that (A) the proposed disposition does not require registration
      of the Transferred Shares under the Securities Act or all appropriate
      action necessary for compliance with the registration requirements of the
      Securities Act or with any exemption from registration available under the
      Securities Act (including Rule 144) has been taken and (B) the proposed
      disposition will not result in the contravention of any transfer
      restrictions applicable to the Transferred Shares under applicable state
      law.

            (v) The Transferee has been furnished with, and has had access to,
      such information as he or she considers necessary or appropriate for
      deciding whether to invest in the Transferred Shares, and the Transferee
      has had an opportunity to ask questions and receive answers from the
      Company regarding the terms and conditions of the issuance of the
      Transferred Shares.

            (vi) The Transferee is aware that his or her investment in the
      Company is a speculative investment that has limited liquidity and is
      subject to the risk of complete loss. The Transferee is able, without
      impairing his or her financial condition, to hold the Transferred Shares
      for an indefinite period and to suffer a complete loss of his or her
      investment in the Transferred Shares.

            (vii) Transferee is an "accredited investor" as defined under
      Exhibit I attached hereto.



            (b) Securities Law Restrictions. Regardless of whether the offering
and sale of Shares under the Plan have been registered under the Securities Act
or have been registered or qualified under the securities laws of any state, the
Company at its discretion may impose restrictions upon the sale, pledge or other
transfer of the Transferred Shares (including the placement of appropriate
legends on stock certificates or the imposition of stop-transfer instructions)
if, in the judgment of the Company, such restrictions are necessary or desirable
in order to achieve compliance with the Securities Act, the securities laws of
any state or any other law.

            (c) Market Stand-Off. In connection with any underwritten public
offering by the Company of its equity securities pursuant to an effective
registration statement filed under the Securities Act, including the Company's
initial public offering, the Transferee shall not directly or indirectly sell,
make any short sale of, loan, hypothecate, pledge, offer, grant or sell any
option or other contract for the purchase of, purchase any option or other
contract for the sale of, or otherwise dispose of or transfer, or agree to
engage in any of the foregoing transactions with respect to, any Transferred
Shares without the prior written consent of the Company or its underwriters.
Such restriction (the "Market Stand-Off") shall be in effect for such period of
time following the date of the final prospectus for the offering as may be
requested by the Company or such underwriters. In no event, however, shall such
period exceed 180 days. The Market Stand-Off shall in any event terminate two
years after the date of the Company's initial public offering. In the event of
the declaration of a stock dividend, a spin-off, a stock split, an adjustment in
conversion ratio, a recapitalization or a similar transaction affecting the
Company's outstanding securities without receipt of consideration, any new,
substituted or additional securities which are by reason of such transaction
distributed with respect to any Shares subject to the Market Stand-Off, or into
which such Shares thereby become convertible, shall immediately be subject to
the Market Stand-Off. In order to enforce the Market Stand-Off, the Company may



impose stop-transfer instructions with respect to the Transferred Shares until
the end of the applicable stand-off period. The Company's underwriters shall be
beneficiaries of the agreement set forth in this Subsection (c). This Subsection
(c) shall not apply to Shares registered in the public offering under the
Securities Act, and the Transferee shall be subject to this Subsection (c) only
if the directors and officers of the Company are subject to similar
arrangements.

      t 12 (d) Rights of the Company. The Company shall not be required to (i)
transfer on its books any Transferred Shares that have been sold or transferred
in contravention of this Agreement or (ii) treat as the owner of Transferred
Shares, or otherwise to accord voting, dividend or liquidation rights to, any
Subsequent Transferee to whom Transferred Shares have been transferred in
contravention of this Agreement.

SECTION 4. SUCCESSORS AND ASSIGNS.

            Except as otherwise expressly provided to the contrary, the
provisions of this Agreement shall inure to the benefit of, and be binding upon,
the Company and its successors and assigns and be binding upon the Transferee
and the Transferee's legal representatives, heirs, legatees, distributees,
assigns and transferees by operation of law, whether or not any such person has
become a party to this Agreement or has agreed in writing to join herein and to
be bound by the terms, conditions and restrictions hereof.

SECTION 5. NO RETENTION RIGHTS.

            Nothing in this Agreement or in the Plan shall confer upon the
Transferee any right to continue providing services to the Company for any
period of specific duration or interfere with or otherwise restrict in any way
the rights of the Company or of the Transferee, which rights are hereby
expressly reserved by each, to terminate his or her service at any time and for
any reason, with or without cause.

SECTION 6. TAX ELECTION.

            The acquisition of the Transferred Shares may result in adverse tax
consequences that may be avoided or mitigated by filing an election under Code



Section 83(b). Such election may be filed only within 30 days after the date of
transfer set forth in the Summary of Stock Grant. The Transferee should consult
with his or her tax advisor to determine the tax consequences of acquiring the
Transferred Shares and the advantages and disadvantages of filing the Code
Section 83(b) election. The Transferee acknowledges that it is his or her sole
responsibility, and not the Company's, to file a timely election under Code
Section 83(b), even if the Transferee requests the Company or its
representatives to make this filing on his or her behalf.

SECTION 7. LEGENDS.

            All certificates evidencing Transferred Shares shall bear the
following legends:

      "THE SHARES REPRESENTED HEREBY MAY NOT BE SOLD, ASSIGNED, TRANSFERRED,
      ENCUMBERED OR IN ANY MANNER DISPOSED OF, EXCEPT IN COMPLIANCE WITH THE
      TERMS OF A WRITTEN AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED HOLDER
      OF THE SHARES (OR THE PREDECESSOR IN INTEREST TO THE SHARES). SUCH IMPOSES
      CERTAIN FORFEITURE CONDITIONS UPON TERMINATION OF SERVICE WITH THE
      COMPANY. THE SECRETARY OF THE COMPANY WILL UPON WRITTEN REQUEST FURNISH A
      COPY OF SUCH AGREEMENT TO THE HOLDER HEREOF WITHOUT CHARGE."

      "THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
      SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR
      OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH



      ACT OR AN OPINION OF COUNSEL, SATISFACTORY TO THE COMPANY AND ITS COUNSEL,
      THAT SUCH REGISTRATION IS NOT REQUIRED."

If required by the authorities of any state in connection with the issuance of
the Transferred Shares, the legend or legends required by such state authorities
shall also be endorsed on all such certificates.

writing. It shall be deemed effective upon (i) personal delivery, (ii) deposit
with the United States Postal Service, by registered or certified mail, with
postage and fees prepaid or (iii) deposit with Federal Express Corporation, with

most recently provided to the Company in accordance with this Section 9.
