d. Costs for any facility resources provided by NTEC, which are not indicated in paragraph 1 above, shall be borne by the Licensee.

e. As part of this License Agreement, Licensee will grant NTEC a warrant for the transfer of equity to NTEC, under the terms outlined in the Stock Purchase Warrant attached as Exhibit E.

3. It is understood by the parties that this License Agreement constitutes a License Agreement, not a lease, and that the relationship of the parties hereunder in respect to occupancy of the Premises at NTEC is that of Licensor and Licensee, and not that of landlord and tenant. As such, NTEC reserves the right to change space assignments or to terminate this License Agreement by written notice if the assigned Premises does not function as a place of business for Licensee for more than four (4) consecutive weeks, except for normal and customary business closures and holidays, or if Licensee in NTEC's reasonable discretion no longer meets the criteria (see attached Exhibit D) for participation in the NTEC program. The foregoing notwithstanding, NTEC shall not change space assignments unless and until equivalent space equipped with amenities and utilities comparable to existing space is available and ready for immediate occupancy.

a. The Premises are licensed for the purpose of furthering Licensee's business objectives as outlined in Licensee's business plan and approved by NTEC, pertinent portions of which are attached hereto and incorporated herein by reference as Exhibit F. Notwithstanding Paragraph 11 herein and without limiting the generalities of the foregoing, if NTEC has reason to believe at any time that Licensee is no longer following its business plan as approved by NTEC and attached as Exhibit F, NTEC retains the right, in its reasonable discretion, to review Licensee's status, and, if in NTEC's reasonable discretion, Licensee's then current status is not in accord with Licensee's business plan or consistent with the goals of NTEC, Licensee will be deemed in default of the License Agreement. The license granted in Section 1 of this Agreement may terminate fifteen (15) days after Licensee defaults in its obligations to NTEC. Further, if Licensee or any person or entity claiming rights by, through, or under Licensee, refuses to surrender possession of the Premises after such fifteen (15)n day period, then Licensee, or such person or entity, will be deemed a "tenant" committing a "forcible detainer" for purposes of Chapter 24 {Forcible Entry and Detainer ) of the Texas Property Code. Additionally, Licensee will execute concurrent with this License Agreement, a Services Agreement. A default related to the Services Agreement will also constitute a default for purposes of the License Agreement. If suchdefault is not cured within the prescribed timeframes both agreements will be deemed in default.

b. In the event Licensee fails to pay any past due Monthly Payment within ten (10) days of receipt of written notice from NTEC, then NTEC shall have the right to terminate this License immediately and Licensee shall bear the costs of collection incurred by NTEC.

c. In the event that any default hereunder by Licensee other than non- payment of Monthly Payments remains uncured for a period of ten (10) days after Licensee's receipt of written notice from NTEC specifying such default, then NTEC shall have the right to terminate this License immediately.

d. Further, either party may terminate this Agreement upon ten (10) days written notice, so long as Licensee is not in default of this Agreement at that time.

e. If this License Agreement is terminated for any reason, Licensee shall vacate its Premises at NTEC within five (5) business days of the termination date. For each day that Licensee continues to occupy its Premises at NTEC beyond the termination date, Licensee shall be liable for 5% of its regular Monthly Payment per day. Licensee shall also be liable for all costs, legal and otherwise, incurred by NTEC in facilitating Licensee's vacating of its Premises.

4. Licensee shall obtain and maintain at its expense, throughout the term of this License Agreement, insurance against loss or liability in connection with bodily injury, death, property damage or destruction, occurring within the Premises at NTEC or arising out of the use of the Premises at NTEC by Licensee or its agents, employees, officers, licensees, invitees, visitors, and guests, under one or more policies of Comprehensive General Liability insurance or its equivalent having such limits as to each as are reasonably required by NTEC from time to time, but in any event of not less than a minimum coverage of One Million Dollars ($1,000,000) for bodily injury to or death of any one person during any one occurrence, One Million Dollars ($ 1,000,000) for bodily injury to or death of all persons in any one occurrence, and One Million Dollars ($ 1,000,000) for property damage or destruction during any one occurrence.

NTEC and Hall 2611 Internet Associates, Ltd. (Building owners) shall be listed as "additional insured" on all insurance policies. The above-referenced insurance shall contain a provision that states that it cannot be canceled except upon thirty (30) days' written notice to all additional insurers. NTEC shall be furnished with two (2) copies of said policy or certificate of insurance no less than five (5) business days prior to the effective date of this License Agreement.

5. NTEC and its officers, agents and employees, shall not be liable for any injury, damage or loss to person (including Licensee invitees), equipment, facilities, or property occurring on or about the Premises at NTEC caused by the use, negligence or misconduct of Licensee, its officers, agents, employees, or invitees. Licensee shall defend, indemnify and hold harmless NTEC, its officers, agents, and employees from any and all losses, expenses, demands, actions, suits, claims or liabilities of whatsoever nature resulting from any injury or death to any person or any property damage arising out of Licensee's use or occupancy of the Premises and affiliation or connection with NTEC including but not limited to actions in furtherance of its business plan, research, and use of the Premises at NTEC. Licensee shall also defend, indemnify and hold harmless NTEC, its officers, agents, and employees from any and all claims resulting from a breach of this Agreement.

6. If, during the term of this License Agreement, the Premises at NTEC are so damaged by fire or other catastrophe that the Premises are rendered unfit for occupancy and said Premises cannot be repaired within thirty (30) days of the happening of such injury; then Licensee shall have the option to declare this Agreement void from the date of such injury. In such case, the Monthly Payment shall be apportioned to the date of damage and NTEC shall

reimburse Licensee for the balance and shall repossess the Premises. If the damage is such that the Premises are unfit for occupancy but can be repaired within thirty (30) days thereafter, NTEC shall enter and repair with reasonable promptness, and this License Agreement shall not be affected except that the Monthly Payment shall be suspended while such repairs are being made. In case of any damage which shall not render the Premises unfit for occupancy, this License Agreement shall not be affected, but NTEC may enter upon and repair the said Premises with reasonable promptness.

7. Licensee shall maintain the Premises in its original condition to the satisfaction of NTEC, normal wear and tear excepted. Prior to the commencement date of this License Agreement, a joint survey of the Premises, indicating its exact condition, shall be made by representatives of both Licensee and NTEC. A written report of said survey shall be attached hereto and another survey shall be made upon termination of this License. These surveys are attached as Exhibit G. Licensee shall repair any damage to the Premises revealed by such survey, normal wear and tear excepted. Otherwise, NTEC shall make the required repairs and/or replacement of damaged property; and shall provide Licensee with an invoice representing the costs to NTEC of making said repairs, said invoice due and payable by Licensee upon receipt. Licensee, under this paragraph, is deemed to have accepted the Premises in the condition existing on the commencement date of this License Agreement. Licensee is not liable for damage to the Premises due to the sole negligence of NTEC.

8. On or before the Effective Date, Licensee shall pay to NTEC a sum equal to one (1) month's Monthly Payment to be held by NTEC as security deposit for the full, faithful and punctual performance by Licensee of the Licensee's terms, covenants and conditions contained herein for the full term of this License Agreement. If, during the term of this License, Licensee is granted additional space at NTEC, an additional security deposit payment may be required.

If, at any time, Licensee fails to fully, faithfully and punctually perform any of the terms, covenants and conditions contained herein, then NTEC may apply any part or the whole of said security deposit to indemnify NTEC for any damage NTEC may have suffered or will suffer because of such failure to perform by the Licensee and NTEC shall in no way be precluded from recovering in addition to the said security deposit, any other damages or expenses that NTEC may suffer by reason of any violation by the Licensee of the terms, covenants and conditions contained herein.

If this License Agreement is terminated prior to the expiration of the term thereof by the agreement of the parties, or in accordance with the terms contained in this License Agreement, and the Licensee has fully, faithfully and punctually performed all of the Licensee's terms, covenants and conditions contained herein up to the date of termination thereof, then the deposit shall be returned by NTEC to the Licensee.

9. Except as specified in paragraphs 3 and 6, NTEC shall not be responsible to Licensee for any damages or inconveniences caused by interruption of business or inability to occupy the Premises for any reason whatsoever, provided that Licensee's Monthly Payment shall be abated or proportionately reduced according to the extent to which Licensee is deprived of such use if the business interruption is due to circumstances caused by NTEC that are not in the normal course of business or that are not a part of normal operating procedures at NTEC.

10. Licensee shall not assign this License, either in whole, or in part, to others without the prior written consent of NTEC. A change in control of Licensee shall constitute an assignment.

11. Licensee's admittance to the NTEC program is based, in part, on NTEC's review of Licensee's business concept, objectives and plans. NTEC reserves the right to approve or deny, at its sole discretion, Licensee's use of the Premises beyond that anticipated in connection with Licensee's approved business plan. Use of the Premises and other facilities and services made available to Licensee by NTEC shall be in furtherance of Licensee's business concept objectives and plans and the Premises are not to be used for any illicit or illegal purposes.

Licensee agrees to abide by NTEC's policies and regulations concerning the use of any such facility or service universally applicable to all other licensees at NTEC. Licensee's use of the Premises and equipment contained therein may not interfere, in any manner, with use by other licensees of nearby facilities and equipment. Research involving the use of animals or human subjects by Licensee is not permitted.

12. As a material inducement for NTEC to enter into this License Agreement, Licensee represents and warrants that Licensee will maintain and use the Premises free from contamination by or from any "hazardous substances" or "hazardous wastes" (as such terms are defined and/or used in applicable state or federal law or the regulations issued under them, ncluding without limitation, the federal Comprehensive Environmental Response, Compensation and Liability Act ["CERCLA"] and the Resource Conservation and Recovery Act ["RCRA"]). Licensee shall not engage in operations at or upon the Premises which involve the generation, manufacture, refining, transportation, treatment, storage, handling or disposal of

hazardous substances or hazardous wastes except in strict compliance with all applicable federal, state and local laws, regulations, rules, orders and permits. Licensee further covenants that it will not cause or permit to exist as a result of an intentional or unintentional action or omission, the releasing, spilling, leaking, pumping, pouring, emitting, emptying or dumping from, or about the Premises of any such hazardous substances or hazardous wastes.

Licensee agrees to indemnify and hold harmless NTEC, its subsidiaries and affiliates, and any officer, director, shareholder, employee, or any agent of NTEC or its affiliates, subsidiaries, successors or assigns (collectively, the "Indemnified Parties"), from any and all liability, damages, costs, claims, suits, actions, legal or administrative proceedings, interest, losses, expenses, and reasonable attorneys' fees, and appellate attorneys' fees (including any such fees and expenses incurred in enforcing this indemnity) resulting from, arising out of, or in any way connected with breach or alleged breach of the provisions of the preceding paragraph of this paragraph, including but not limited to monetary damages, expenses, injury to or the death of any person (including that of any Indemnified Party) or physical damage to property of any kind wherever located and by whomever owned (including that of any Indemnified Party) arising out of or in any way connected with the presence on, in or under the Premises of any asbestos polychlorinated biphenyls (PCB's) or the generation, handling, storage or disposal of any

hazardous substances or hazardous wastes or medical or biological wastes in violation of the provisions of the preceding paragraph of this paragraph. This indemnification is an independent covenant and shall survive the termination of this License Agreement.

13. NTEC reserves the right at all times to control all facilities licensed hereunder, and to enforce all applicable necessary laws, rules and regulations without obligation or assumption of any responsibility to do so.

14. At the request of NTEC, but not less frequently than at six (6) month intervals, Licensee agrees to review its current and prospective business status with NTEC. Progress will be monitored in relation to the most recent business plan and established, measurable business objectives, which are regularly reviewed and approved by both Licensee and NTEC. If, in NTEC's sole discretion, the Licensee's current status is not sufficiently in accord with the most recent previously reviewed plan, a default condition will exist.

15. During the term of this Agreement and for six (6) months thereafter, the Licensee shall not solicit for hire or employ, nor knowingly allow any if its employees, agents, officers, or representatives to solicit for hire or employ, any employee(s) of other licensees of NTEC without the express written permission of the other licensees.

16. NTEC will install all locks at the Suite entry doors and to said Premises for each Office Space allocated to Licensee as noted in Exhibit B to said Premises and provide two (2) keys for each lock to Licensee. Licensee will execute, concurrent with this Agreement, the Key Agreement covering the keys noted above and any other keys or related access materials required by Licensee for access to the Building, Suite or Premises, attached as Exhibit H. NTEC will have the master key to each lock, and may enter Premises, at reasonable times, for inspection, maintenance, or repair, or for any other necessary reason. Entry for other than normal maintenance and inspection activities shall be preceded by appropriate notice to Licensee. In the event of an emergency, notice will be given at the first reasonable opportunity, even after the fact.

17. Unless in default of this Agreement, Licensee shall have the right to remove any and all equipment, goods, fixtures and other property which it has placed or affixed within or to Premises, provided Licensee repairs all damage to Premises caused by such removal and returns the Premises to its condition as of the Effective Date of this License Agreement. Licensee shall not remove improvements made to the facilities by NTEC or on behalf of NTEC during the Licensee's occupancy.

18. Licensee shall not represent or imply that it is affiliated in any way with NTEC other than as a Licensee and participant in the NTEC program. Licensee shall not represent or imply that its activities, products or services are endorsed or approved by NTEC. Any public announcements by Licensee, which mention NTEC or Licensee's relationship with NTEC, shall be submitted to NTEC for review and approval of said language relating to the Licensee's relationship with NTEC.

19. Nothing contained in this Agreement shall create any partnership or joint venture between the parties. Neither party may pledge the credit of the other or make any binding commitment on the part of the other.

20. This Agreement and the related Service Agreement, including any and all exhibits referred to in those Agreements or delivered under the terms of those Agreements, contains all the understandings and agreements of the parties relating to the subject matter hereof and supersedes all prior or contemporaneous agreements, proposals, etc., and may be changed only by an agreement in writing signed by the parties hereto.

21. Any notice, demand, consent, approval, request or other communication or document to be given hereunder to a party hereto ("Notice") (a) shall be in writing; (b) shall be deemed to have been given (i) on the 3rd business day after being sent as certified or registered mail in the United States mail or other nationally recognized carrier, postage prepaid, return receipt requested, or (ii) on the next business day after being deposited (with instructions to deliver it on such business day) with a reputable overnight courier service (if such Party's receipt thereof is acknowledged in writing) on being given by hand or other actual delivery to such Party; and (c) (i) if given to NTEC, shall be addressed to ▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇, ▇▇▇▇▇, and (ii) if given to Licensee, shall be addressed to ▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇, ▇▇▇▇▇.

3. Electrical Equipment. NTEC has not agreed to furnish electrical capacity for the Premises in excess of three (3) ▇▇▇▇▇ per Rentable Square Feet. If Licensee requires electricity in excess of that which NTEC has agreed to provide, NTEC will, upon the written request of such Licensee and the written agreement of such Licensee to pay all costs and expenses for the same, make reasonable efforts to supply such service through the then existing feeders servicing the Building. No machinery or mechanical equipment other than ordinary portable business machines may be installed or operated in Licensee's premises without NTEC's prior written consent, which consent shall not be unreasonably withheld or delayed, and in no case (even where the same are of a type so excepted or as so consented to by NTEC) shall any machines or mechanical equipment be so placed or operated so as to impair or interfere with any of the Building's services or the proper and economic heating, cooling, cleaning or other servicing of any portion of the Building or so as to disturb other licensees. Machines and mechanical equipment which may be permitted to be installed and used in a licensee's premises shall be so equipped, installed and maintained by such licensee as to prevent any disturbing noise, vibration or electrical or other interference from being transmitted from such premises to any other area of the Building.

Subject to the terms and conditions hereinafter setnforth, the Holder is entitled, upon surrender of this Warrant at the principal office of theb Company (or at such other place as the Company shall notify the holder hereof in writing), to purchase from the Company _1,406,000____fully paid and non-assessable shares of Common Stock, par value $_.0001_ per share (the "Common Stoctf'), of the Company (as adjusted pursuant to Section 7 hereof, the "Shares") for the purchase price specified in Section 2 below.

2. Purchase Price. The purchase price for the Shares is $__.0001_ per share. Such price shall be subject to adjustment pursuant to Section 7 hereof (such price, as adjusted from time to time, is herein referred to as the "Warrant Price").

3. Exercise Period. This Warrant is exercisable in whole or in part at any time from the date hereof through April 7, 2014.

4. Method of Exercise. While this Warrant remains outstanding and exercisable in accordance with Section 3 above, the Holder may exercise, in whole or in part, the purchase rights evidenced hereby. Such exercise shall be effected by:

(a) surrender of this Warrant, together with a duly executed copy of the form of Exercise Notice attached hereto, to the Secretary of the Company at its principal offices, and the payment to the Company of an amount equal to the aggregate purchase price for the number of Shares being purchased, which shall be a whole number of shares; or

(b) if the Common Stock is publicly traded as of such date, the instruction to retain that whole number of Shares having a value equal to the aggregate exercise price of the Shares as to which this Warrant is being exercised and to issue to the Holder the remainder of such Shares computed using the following formula:

X= Y(A-B)

Where:

X = the number of shares of Common Stock to be issued to the Holder.

Y= the number of shares of Common Stock as to which this Warrant is being exercised.

A = the fair market value of one share of Common Stock. B = the Warrant Price. As used herein, the "fair market value of one share of Common Stock" shall mean:

(1) Except in the circumstances described in clause (2) hereof, the price per share of the Common Stock determined in good faith by the Board of Directors of the Company; or

5. Certificates for Shares; Partial Exercise of Warrants.

(a) Upon the exercise of the purchase rights evidenced by this Warrant, one or more certificates for the number of Shares so purchased shall be issued as soon as practicable thereafter, and in any event within thirty (30) days of the delivery of the Exercise Notice.

(b) If this Warrant is surrendered for partial exercise, the Company shall execute and deliver to the Holder of the Warrant, without charge to the Holder, a new Warrant exercisable for an aggregate number of shares of Common Stock equal to the unexercised portion of the surrendered Warrant.

6. Reservation of Shares. The Company covenants that it will at all times keep available such number of authorized shares of its Common Stock, free from all preemptive rights with respect thereto, which will be sufficient to permit the exercise of this Warrant for the full number of Shares specified herein. The Company further covenants that such Shares, when issued pursuant to the exercise of this Warrant, will be duly and validly issued, fully paid and non-assessable and free from all taxes, liens and charges with respect to the issuance thereof.

7. Adjustment of Warrant Price and Number of Shares. The number and kind of securities purchasable upon exercise of this Warrant and the Warrant Price shall be subject to adjustment from time to time as follows:

(a) Stock Dividends, Subdivisions, Combinations and Other Issuances. If the Company shall at any time prior to the expiration of this Warrant subdivide its Common Stock, by stock split or otherwise, combine its Common Stock or issue additional shares of its Common Stock as a dividend with respect to any shares of its Common Stock, the number of Shares issuable on the exercise of this Warrant shall forthwith be proportionately increased in the case of a subdivision or stock dividend and proportionately decreased in the case of a combination. Appropriate adjustments shall also be made to the purchase price payable per share, but the aggregate purchase price payable for the total number of Shares purchasable under this Warrant (as adjusted) shall remain the same. Any adjustment under this Section 7(a) shall become effective at the close of business on the date the subdivision or combination becomes effective or as of the record date of such dividend, or, in the event that no record date is fixed, upon the making of such dividend.

(b) Reclassification, Reorganization, Merger, Sale or Consolidation. In the event of any reclassification, capital reorganization or other change in the Common Stock of the Company (other than as a result of a subdivision, combination or stock dividend provided for in Section 7(a) above) or in the event of a consolidation or merger of the Company with or into, or the sale of all or substantially all of the properties and assets of the Company, to any person, and in connection therewith consideration is payable to holders of Common Stock in cash, securities or other property, then as a condition of such reclassification, reorganization or change, consolidation, merger or sale, lawful provision shall be made, and duly executed documents evidencing the same shall be delivered to the Holder, so that the Holder shall have the right at any time prior to the expiration of this Warrant to purchase, at a total price equal to that payable upon the exercise of this Warrant immediately prior to such event, the kind and amount of cash, securities or other property receivable in connection with such reclassification, reorganization or change, consolidation, merger or sale, by a holder of the same number of shares of Common Stock as were exercisable by the Holder immediately prior to such reclassification, reorganization or change, consolidation, merger or sale. In any such case, appropriate provisions shall be made with respect to the rights and interest of the Holder so that the provisions hereof shall thereafter be applicable with respect to any cash, securities or property deliverable upon exercise hereof. Notwithstanding the foregoing, (i) if the Company merges or consolidates with, or sells all or substantially all of its property and assets to, any other person, and consideration is payable to holders of Common Stock in exchange for their Common Stock in connection with such merger, consolidation or sale which consists solely of cash, or (ii) in the event of the dissolution, liquidation or winding up of the Company, then the Holder shall be entitled to receive distributions on the date of such event on an equal basis with holders of Common Stock as if this Warrant had been exercised immediately prior to such event, less the Warrant Price. Upon receipt of such payment, if any, the rights of the Holder shall terminate and cease, and this Warrant shall expire. In case of any such merger, consolidation or sale of

assets, the surviving or acquiring person and, in the event of any dissolution, liquidation or winding up of the Company, the Company shall promptly, after receipt of this surrendered Warrant, make payment by delivering a check in such amount as is appropriate (or, in the case of consideration other than cash, such other consideration as is appropriate) to such person as it may be directed in writing by the Holder surrendering this Warrant.

(c) Certain Distributions. In case the Company shall fix a record date for the making of a dividend or distribution of cash, securities or property to all holders of Common Stock (excluding any dividends or distributions referred to in Sections 7(a) or 7(b) above), the number of Shares purchasable upon an exercise of this Warrant after such record date shall be adjusted to equal the product obtained by multiplying the number of Shares purchasable upon an exercise of this Warrant immediately prior to such record date by a fraction, the numerator of which shall be the Warrant Price immediately prior to such distribution, and the denominator of which shall be the Warrant Price immediately prior to such distribution, less the fair market value per Share, as determined by the Holder, of the cash, securities or property so distributed. Such adjustment shall be made successively whenever any such distribution is made and shall become effective on the effective date of distribution.

8. Pre-Exercise Rights. Prior to exercise of this Warrant, the Holder shall not be entitled to any rights of a shareholder with respect to the Shares, including without limitation, the right to vote such Shares, receive preemptive rights or be notified of shareholder meetings, and the Holder shall not be entitled to any notice or other communication concerning the business or affairs of the Company.

9. Restricted Securities. The Holder understands that this Warrant and the Shares purchasable hereunder constitute "restricted securities" under the federal securities laws inasmuch as they are being, or will be, acquired from the Company in transactions not involving a public offering and accordingly may not, under such laws and applicable regulations, be resold or transferred without registration under the Securities Act of 1933, as amended, or an applicable exemption from registration. The Holder further acknowledges that the Shares and any other securities issued upon exercise of this Warrant shall bear a legend substantially in the form of the legend appearing on the face hereof.

10. Certification of Investment Purpose. Unless a current registration statement under the Securities Act of 1933, as amended, shall be in effect with respect to the securities to be issued upon exercise of this Warrant, the Holder hereof, by accepting this Warrant, covenants and agrees that, at the time of exercise hereof, the Holder will deliver to the Company a written certification that the securities acquired by the Holder are acquired for investments purposes only and that such securities are not acquired with a view to, or for sale in connection with, any distribution thereof.

11. Successors and Assigns. The terms and provisions of this Warrant shall inure to the benefit of, and be binding upon, the Company and the Holder and their respective successors and assigns.

12. Governing Law. This Warrant shall be governed by the laws of the State of Texas, excluding the conflicts of laws provisions thereof.
