At the Closing, the Make Good Pledgor shall deliver, or cause to be delivered, to the Escrow Agent certificates evidencing an aggregate of 1,000,000 shares of the Company’s Common Stock (the “Escrow Shares”), along with stock powers executed in blank (or such other signed instrument of transfer acceptable to the Company’s Transfer Agent). Also at the Closing the Indemnitor shall surrender for cancellation a total of 1,000,000 shares outstanding in her name.

          3.     Representations of Make Good Pledgor. The Make Good Pledgor (as to itself and its Escrowed Shares) hereby represents and warrants to the Indemnitor as follows:

4.     Disbursement of Escrow Shares.

(a)     If the 2008 Income is equal to or greater than USD 7,000,000, then all of the Escrow Shares shall be released and returned to Make Good Pledgor.

                    (b)      If the 2008 Income is less than USD 7,000,000, but equal to or greater than USD 6,000,000, then 50% of the Escrow Shares shall be released and issued to Indemnitor and 50% returned to Make Good Pledgor.

The Company and Make Good Pledgor covenant and agree to provide the Escrow Agent with certified tax identification numbers by furnishing appropriate forms W-9 or W-8 and such other forms and documents that the Escrow Agent may request, including appropriate W-9 or W-8 forms for the Indemnitor. The Company, Make Good Pledgor and the Indemnitor understands that if such tax reporting documentation is not provided and certified to the Escrow Agent, the Escrow Agent may be required by the Internal Revenue Code of 1986, as amended, and the Regulations promulgated thereunder, to withhold a portion of any interest or other income earned on the investment of the Escrow Property.

         6.    Notice of Filings. The Company agrees to promptly provide the Make Good Pledgor written notice of the filing with the Commission of any financial statements or reports referenced herein.

         7.    Escrow Shares.

Until such time as (if at all) the Escrow Shares are required to be delivered pursuant to the Stock Purchase Agreement and in accordance with this Make Good Agreement, (i) any dividends payable in respect of the Escrow Shares and all voting rights applicable to the Escrow Shares shall be retained by Make Good Pledgor and (ii) should the Escrow Agent receive dividends or voting materials, such items shall not be held by the Escrow Agent, but shall be passed immediately on to the Make Good Pledgor and shall not be invested or held for any time longer than is needed to effectively re-route such items to the Make Good Pledgor.

The Make Good Pledgor shall be responsible for all taxes resulting from any such conversion or exchange.

Assuming the Make Good Pledgor provides good and valid title to the Escrow Shares to be transferred and delivered on behalf of the Make Good Pledgor to the Indemnitor hereunder, free and clear of all liens, encumbrances, equities or claims, the Escrow Agent will ensure that upon delivery of the Escrow Shares, good and valid title to the Escrow Shares, free and clear of all liens, encumbrances, equities or claims will pass to the Indemnitor. The Escrow Agent shall not take any action which could impair Indemnitor’s rights in the Escrow Shares. The Escrow Agent shall not sell, transfer, assign or otherwise dispose of (by operation of law or otherwise) or grant any option with respect to any Escrow Shares prior to the termination of this Agreement.

Escrow Agent also is authorized to institute an appropriate interpleader action upon receipt of a written letter of direction executed by the parties so directing Escrow Agent. If Escrow Agent is directed to institute an appropriate interpleader action, it shall institute such action not prior to thirty (30) days after receipt of such letter of direction and not later than sixty (60) days after such date. Any interpleader action instituted in accordance with this Section 8 shall be filed in any court of competent jurisdiction in the State of Texas, and the Escrow Shares in dispute shall be deposited with the court and in such event Escrow Agent shall be relieved of and discharged from any and all obligations and liabilities under and pursuant to this Make Good Agreement with respect to the Escrow Shares and any other obligations hereunder.

9.     Exculpation and Indemnification of Escrow Agent.

(a)     Escrow Agent is not a party to, and is not bound by or charged with notice of any agreement out of which this escrow may arise. Escrow Agent acts under this Make Good Agreement as a depositary only and is not responsible or liable in any manner whatsoever for the sufficiency, correctness, genuineness or validity of the subject matter of the escrow, or any part thereof, or for the form or execution of any notice given by any other party hereunder, or for the identity or authority of any person executing any such notice. Escrow Agent will have no duties or responsibilities other than those expressly set forth herein. Escrow Agent will be under no liability to anyone by reason of any failure on the part of any party hereto (other than Escrow Agent) or any maker, endorser or other signatory of any document to perform such person’s or entity’s obligations hereunder or under any such document. Except for this Make Good Agreement and instructions to Escrow Agent pursuant to the terms of this Make Good Agreement, Escrow Agent will not be obligated to recognize any agreement between or among any or all of the persons or entities referred to herein, notwithstanding its knowledge thereof.

                     (b)     Escrow Agent will not be liable for any action taken or omitted by it, or any action suffered by it to be taken or omitted, absent gross negligence or willful misconduct. Escrow Agent may rely conclusively on, and will be protected in acting upon, any order, notice, demand, certificate, or opinion or advice of counsel (including counsel chosen by Escrow Agent), statement, instrument, report or other paper or document (not only as to its due execution and the validity and effectiveness of its provisions, but also as to the truth and acceptability of any information therein contained) which is reasonably believed by Escrow Agent to be genuine and to be signed or presented by the proper person or persons. The duties and responsibilities of the Escrow Agent hereunder shall be determined solely by the express provisions of this Make Good Agreement and no other or further duties or responsibilities shall be implied, including, but not limited to, any obligation under or imposed by any laws of the State of Nevada upon fiduciaries. THE ESCROW AGENT SHALL NOT BE LIABLE, DIRECTLY OR INDIRECTLY,

FOR ANY (I) DAMAGES, LOSSES OR EXPENSES ARISING OUT OF THE SERVICES PROVIDED HEREUNDER, OTHER THAN DAMAGES, LOSSES OR EXPENSES WHICH HAVE BEEN FINALLY ADJUDICATED TO HAVE DIRECTLY RESULTED FROM THE ESCROW AGENT’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, OR (II) SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGES OR LOSSES OF ANY KIND WHATSOEVER (INCLUDING, WITHOUT LIMITATION, LOST PROFITS), EVEN IF THE ESCROW AGENT HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSSES OR DAMAGES AND REGARDLESS OF THE FORM OF ACTION.

                     (c)     The Company and the Make Good Pledgor each hereby, jointly and severally, indemnify and hold harmless each of Escrow Agent and any of its principals, partners, agents, employees and affiliates from and against any expenses, including reasonable attorneys’ fees and disbursements, damages or losses suffered by Escrow Agent in connection with any claim or demand, which, in any way, directly or indirectly, arises out of or relates to this Make Good Agreement or the services of Escrow Agent hereunder; except, that if Escrow Agent is guilty of willful misconduct or gross negligence under this Make Good Agreement, then Escrow Agent will bear all losses, damages and expenses arising as a result of its own willful misconduct or gross negligence. Promptly after the receipt by Escrow Agent of notice of any such demand or claim or the commencement of any action, suit or proceeding relating to such demand or claim, Escrow Agent will notify the other parties hereto in writing. For the purposes hereof, the terms “expense” and “loss” will include all amounts paid or payable to satisfy any such claim or demand, or in settlement of any such claim, demand, action, suit or proceeding settled with the express written consent of the parties hereto, and all costs and expenses, including, but not limited to, reasonable attorneys’ fees and disbursements, paid or incurred in investigating or defending against any such claim, demand, action, suit or proceeding. The provisions of this Section 9 shall survive the termination of this Make Good Agreement, and the resignation or removal of the Escrow Agent.

10.     Compensation of Escrow Agent. Escrow Agent shall be entitled to compensation for its services as stated in the fee schedule attached hereto as Exhibit A, which compensation shall be paid by the Company. The fee agreed upon for the services rendered hereunder is intended as full compensation for Escrow Agent’s services as contemplated by this Make Good Agreement; provided, however, that in the event that Escrow Agent renders any material service not contemplated in this Make Good Agreement, or there is any assignment of interest in the subject matter of this Make Good Agreement, or any material modification hereof, or if any material controversy arises hereunder, or Escrow Agent is made a party to any litigation pertaining to this Make Good Agreement, or the subject matter hereof, then Escrow Agent shall be reasonably compensated by the Company for such extraordinary services and reimbursed for all costs and expenses, including reasonable attorney’s fees, occasioned by any delay, controversy, litigation or event, and the same shall be recoverable from the Company. Prior to incurring any costs and/or expenses in connection with the foregoing sentence, Escrow Agent shall be required to provide written notice to the Company of such costs and/or expenses and the relevancy thereof and Escrow Agent shall not be permitted to incur any such costs and/or expenses which are not related to litigation prior to receiving written approval from the Company, which approval shall not be unreasonably withheld.

          11.       Resignation of Escrow Agent. At any time, upon ten (10) Business Days’ written notice to the Company, Indemnitor and Make Good Pledgor, Escrow Agent may resign and be discharged from its duties as Escrow Agent hereunder.
