                               FEBRUARY-MARCH 2007

1.       SUBSCRIPTION. Subject to the terms and conditions hereof, the
         undersigned (hereinafter referred to as the "SUBSCRIBER") irrevocably
         tenders this "Subscription" and hereby subscribes for the number of
         Units (as defined in the Offering Memo) set forth on the signature page
         hereto as described in the Confidential Private Placement Memorandum
         attached hereto as EXHIBIT A (the "OFFERING MEMO").

2.       ACCEPTANCE OF SUBSCRIPTION. This Subscription Agreement shall not
         become binding unless (i) this Subscription Agreement is accepted by
         the Company, (ii) the Subscription Amount has been received and
         accepted by the Company, and (iii) such additional closing conditions
         as the Company, in its sole discretion, shall require are satisfied.
         This Subscription shall not be deemed accepted by the Company until
         this Subscription Agreement is signed by a duly authorized officer of
         the Company and returned to Subscriber. If this Subscription is
         accepted, this Subscription Agreement shall become effective as between
         the Company and the Subscriber. If this Subscription is rejected, this
         Subscription Agreement and the Subscription Amount will be returned to
         the Subscriber as soon as reasonably practicable, and this Subscription
         shall be rendered void and of no further force or effect.

3.       ANCILLARY DOCUMENTS. In connection with its subscription, Subscriber
         has executed and delivered the Registration Rights Agreement in the
         form attached hereto as EXHIBIT B (which the Company will counter-sign
         and deliver to Subscriber if it agrees to accept Subscriber's
         subscription) and the Confidentiality Agreement in the form attached
         hereto as EXHIBIT C.

4.       REPRESENTATIONS AND WARRANTIES OF SUBSCRIBER. Subscriber hereby
         represents and warrants to the Company as follows:

         A. The Subscriber is an "accredited investor" (as defined on EXHIBIT D
         hereto) and is domiciled in the state indicated on the signature page
         hereto.

         B. The Securities hereby subscribed for are being acquired by
         Subscriber as the ultimate owner, in good faith, for Subscriber's own
         account, not as a conduit, underwriter, nominee or agent for other
         beneficial or subsequent owners, and not with a view to the resale or
         distribution of any part thereof; Subscriber has no present intention
         of selling, granting any participation in, or otherwise distributing
         the same and has no contract, undertaking, agreement or arrangement
         with any person to transfer, encumber, or grant participations to any
         person, with respect to any of the Securities. The Subscriber warrants
         that any funds which may be tendered for the purchase of Securities
         will not represent funds borrowed by the Subscriber from any person or
         lending institution except to the extent that the Subscriber has a
         source for repaying such funds other than from the sale of the
         Securities subscribed, and that such Securities have not been pledged
         or otherwise hypothecated for any such borrowing.

         C. Subscriber has received and carefully reviewed a copy of the
         Offering Memo and agrees that it, along with all information regarding
         the Company that is publicly available, supersedes any offering memos
         or other materials that the Company previously provided to Subscriber,
         if any.

         D. Subscriber acknowledges that he has been advised that the Securities
         have not been registered under the Act, as amended, or under the
         provision of any state securities laws, on the grounds that the offer
         and sale of the Securities is exempt from registration under the
         provisions of those Statutes as not involving any public offering.

         E. Subscriber acknowledges that the Subscriber has had the reasonable
         opportunity to ask questions and receive answers concerning the
         offering of the Securities and to obtain additional information
         necessary to verify the accuracy of the information furnished in the
         Offering Memo.


                                      -1-




4.       SUCCESSORS AND ASSIGNS. The Subscriber agrees that this Subscription
         Agreement shall be binding upon and inure to the benefit of all the
         parties hereto and their respective heirs, legal representatives,
         successors and assigns.

5.       INDEMNIFICATION. Subscriber understands and is aware of the
         significance to the Company of the foregoing representations,
         agreements and consents, and they are made with the intention that the
         Company may rely upon them. Subscriber acknowledges that he understands
         the meaning and legal consequences of the representations and
         warranties herein, and he hereby agrees to indemnify and hold harmless
         the Company and its officers, affiliates, agents and employees of the
         Company, and the persons who have solicited this subscription, from and
         against any and all loss, damage or liability, including but not
         limited to legal fees and court costs, due to or arising out of a
         breach of any such representations or warranties made by the
         Subscriber.

7.       NUMBER AND GENDER. Whenever the singular number is used in this
         Subscription Agreement and when required by the context, the same shall
         include the plural, and the masculine gender shall include the feminine
         and neuter genders.

9.       APPLICABLE LAW. This Subscription Agreement shall be governed by, and
         construed in accordance with, the laws of the State of Texas, without
         regard to principles of conflicts of laws. Any dispute under this
         Subscription Agreement that is not settled by mutual consent shall be
         finally adjudicated by any federal or state court sitting in Dallas
         County or Collin County, Texas, and each party consents to the
         exclusive jurisdiction of such courts (or any appellate court
         therefrom) over any such dispute. Each party further consents to
         personal jurisdiction in the courts mentioned in the prior sentence. In
         the event that any suit or action is instituted to enforce any
         provision in this Subscription Agreement, the prevailing party in such
         dispute shall be entitled to recover from the losing party all fees,
         costs and expenses of enforcing any right of such prevailing party
         under or with respect to this Subscription Agreement, including without
         limitation, such reasonable fees and expenses of attorneys and
         accountants, which shall include, without limitation, all fees, costs
         and expenses of appeals.
