4. BUYER'S REPRESENTATIONS AND WARRANTIES
5. Buyer is purchasing the Debenture, the Warrants and the Common Stock issuable upon conversion or redemption of the Debenture and exercise of the Warrants in addition to any additional shares issued as a result of the Company's failure to comply with the provisions of the Debenture (the "Conversion Shares" and, collectively with the Debenture and the Warrants, the "Securities") for its own account, for investment purposes only and not with a view towards or in connection with the public sale or distribution thereof in violation of the Securities Act.
6. Buyer is (i) an "accredited investor" within the meaning of Rule 501 of Regulation D under the Securities Act, (ii) experienced in making investments of the kind contemplated by this Agreement, (iii) capable, by reason of its business and financial experience, of evaluating the relative merits and risks of an investment in the Securities, and (iv) able to afford the loss of its investment in the Securities.

8. Buyer understands that the Securities have not been approved or disapproved by the Securities and Exchange Commission (the "Commission") or any state or provincial securities commission.
9. This Agreement has been duly and validly authorized, executed and delivered by Buyer and is a valid and binding agreement of Buyer enforceable against it in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors' rights and remedies generally and except as rights to indemnity and contribution may be limited by federal or state securities laws or the public policy underlying such laws.
10. Neither Buyer nor its affiliates nor any person acting on its or their behalf (i) has the intention of entering into, or will enter into, any put option, short position or other similar instrument or position with respect to the Common Stock while the Debenture is outstanding and (ii) will use at any time shares of Common Stock acquired pursuant to this Agreement, the Debenture or the Warrants to settle any put option, short position or other similar instrument or position that may have been entered into prior to the execution of this Agreement.
11. THE COMPANY'S REPRESENTATIONS
12. Capitalization.
13. The authorized capital stock of the Company consists of (i) 100,000,000 shares of Class A Common Stock and 30,000,000 shares of Preferred Special Voting Stock of which 21,002,791 shares and 0 shares, respectively, are issued and outstanding as of the date hereof and are fully paid and nonassessable. The amount, exercise, conversion or subscription price and expiry date for each outstanding option and other security or agreement to purchase shares of Common Stock is accurately set forth on Schedule III.A.1.
14. The Conversion Shares have been duly and validly authorized and reserved for issuance by the Company, and, when issued by the Company upon conversion of the Debenture will be duly and validly issued, fully paid and nonassessable and will not subject the holder thereof to personal liability by reason of being such holder.
15. Except as disclosed on Schedule III.A.3., there are no preemptive, subscription, "call," right of first refusal or other similar rights to acquire any capital stock of the Company or any of its Subsidiaries (as such term is hereinafter defined) or other voting securities of the Company that have been issued or granted to any person and no other obligations of the Company or any of its Subsidiaries to issue, grant, extend or enter into any security, option, warrant, "call," right, commitment, agreement, arrangement or undertaking with respect to any of their respective capital stock.
16. Organization; Reporting Company Status.

1. The Company is a corporation duly organized, validly existing and in good standing under the laws of the state or jurisdiction in which it is incorporated and is duly qualified as a foreign corporation in all jurisdictions in which the failure so to qualify would reasonably be expected to have a material adverse effect on the business, properties, prospects, condition (financial or otherwise) or results of operations of the Company or on the consummation of any of the transactions contemplated by this Agreement (a "Material Adverse Effect").
2. The Company has registered the Common Stock pursuant to Section 12 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The Common Stock is traded on the OTC Bulletin Board service of the National Association of Securities Dealers, Inc. ("OTCBB") and the Company has not received any notice regarding, and to its knowledge there is no threat of, the termination or discontinuance of the eligibility of the Common Stock for such trading.

1. Authorization. The Company (i) has duly and validly authorized and reserved for issuance shares of Common Stock, which is a number sufficient for the conversion of the Debenture and the exercise of the Warrants in full and (ii) at all times from and after the date hereof shall have a sufficient number of shares of Common Stock duly and validly authorized and reserved for issuance to satisfy the conversion of the Debenture and the exercise of the Warrants in full. The Company understands and acknowledges the potentially dilutive effect on the Common Stock of the issuance of the Conversion Shares upon the conversion of the Debenture and the exercise of the Warrants. The Company further acknowledges that its obligation to issue Conversion Shares upon conversion of the Debenture and the exercise of the Warrants in accordance with this Agreement is absolute and unconditional regardless of the dilutive effect that such issuance may have on the ownership interests of other stockholders of the Company and notwithstanding the commencement of any case under 11 U.S.C. Section 101 et seq. (the "Bankruptcy Code"). In the event the Company is a debtor under the Bankruptcy Code, the Company hereby waives to the fullest extent permitted any rights to relief it may have under 11 U.S.C. Section 362 in respect of the conversion of the Debenture. The Company agrees, without cost or expense to Buyer, to take or consent to any and all action necessary to effectuate relief under 11 U.S.C. Section 362.
2. Authority; Validity and Enforceability. The Company has the requisite corporate power and authority to enter into the Documents (as such term is hereinafter defined) and to perform all of its obligations hereunder and thereunder (including the issuance, sale and delivery to Buyer of the Securities). The execution, delivery and performance by the Company of the Documents and the consummation by the Company of the transactions contemplated hereby and thereby (including, without limitation, the issuance of the Debenture and the issuance and reservation for issuance of the Conversion Shares) have been duly and validly authorized by all necessary corporate action on the part of the Company. Each of the Documents has been duly and validly executed and delivered by the Company and each Document constitutes a valid and binding obligation of the Company enforceable against it in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors' rights and remedies generally and except as rights to indemnity and contribution may be limited by federal or state securities laws or the public policy underlying such laws. The Securities have been duly and validly authorized for issuance by the Company and, when executed and delivered by the Company, will be valid and binding obligations of the Company enforceable against it in accordance with their respective terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors' rights and remedies generally. For purposes of this Agreement, the term "Documents" means (i) this Agreement; (ii) the Registration Rights Agreement dated as of even date herewith between the Company and Buyer, a copy of which is annexed hereto as Exhibit B (the "Registration Rights Agreement"); (iii) the Debenture, and (iv) the Warrants.
3. Validity of Issuance of the Securities. The Debenture and the Warrants as of the Closing Date (as such term is hereinafter defined), and the Conversion Shares upon their issuance in accordance with the Debenture will be validly issued and outstanding, fully paid and nonassessable, and not subject to any preemptive rights, rights of first refusal, tag-along rights, drag-along rights or other similar rights.
4. Non-contravention. The execution and delivery by the Company of the Documents, the issuance of the Securities, and the consummation by the Company of the other transactions contemplated hereby and thereby do not, and compliance with the provisions of this Agreement and other Documents will not, conflict with, or result in any violation of, or default (with or without notice or lapse of time, or both) under, or give rise to a right of termination, cancellation or acceleration of any obligation or loss of a material benefit under, or result in the creation of any Lien (as such term is hereinafter defined) upon any of the properties or assets of the Company or any of its Subsidiaries under, or result in the termination of, or require that any consent be obtained or any notice be given with respect to (i) the Articles of Incorporation or By-Laws of the Company or the comparable charter or organizational documents of any of its Subsidiaries, in each case as amended to the date of this Agreement, (ii) any loan or credit agreement, note, bond, mortgage, indenture, lease, contract or other agreement, instrument or permit applicable to the Company or any of its Subsidiaries or their respective properties or assets or (iii) any Law (as such term is hereinafter defined) applicable to, or any judgment, decree or order of any court or government body having jurisdiction over, the Company or any of its Subsidiaries or any of their respective properties or assets.
5. Approvals. No authorization, approval or consent of any court or public or governmental authority is required to be obtained by the Company for the issuance and sale of the Debenture (or the Conversion Shares) to Buyer as contemplated by this Agreement, except such authorizations, approvals and consents as have been obtained by the Company prior to the date hereof.
6. Commission Filings. The Company has properly and timely filed with the Commission all reports, proxy statements, forms and other documents required to be filed with the Commission under the Securities Act and the Exchange Act since becoming subject to such Acts (the "Commission Filings"). As of their respective dates, (i) the Commission Filings complied in all material respects with the requirements of the Securities Act or the Exchange Act, as the case may be, and the rules and regulations of the Commission promulgated thereunder applicable to such Commission Filings and (ii) none of the Commission Filings contained at the time of its filing any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The financial statements of the Company included in the Commission Filings, as of the dates of such documents, were true and complete in all material respects and complied with applicable accounting requirements and the published rules and regulations of the Commission with respect thereto, were prepared in accordance with generally accepted accounting principles in the United States ("GAAP") (except in the case of unaudited statements permitted by Form 10-Q under the Exchange Act) applied on a consistent basis during the periods involved (except as may be indicated in the notes thereto) and fairly presented the consolidated financial position of the Company and its Subsidiaries as of the dates thereof and the consolidated results of their operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments that in the aggregate are not material and to any other adjustment described therein).
7. Full Disclosure. There is no fact known to the Company (other than general economic or industry conditions known to the public generally) that has not been fully disclosed in writing to Buyer that (i) reasonably could be expected to have a Material Adverse Effect or (ii) reasonably could be expected to materially and adversely affect the ability of the Company to performing its obligations pursuant to the Documents.
8. Absence of Events of Default. No "Event of Default" (as defined in any agreement or instrument to which the Company is a party) and no event which, with notice, lapse of time or both, would constitute an Event of Default (as so defined), has occurred and is continuing.
9. Securities Law Matters. Assuming the accuracy of the representations and warranties of Buyer set forth in Article II, the offer and sale by the Company of the Securities is exempt from (i) the registration and prospectus delivery requirements of the Securities Act and the rules and regulations of the Commission thereunder and (ii) the registration and/or qualification provisions of all applicable state and provincial securities and "blue sky" laws. The Company shall not directly or indirectly take, and shall not permit any of its directors, officers or Affiliates directly or indirectly to take, any action (including, without limitation, any offering or sale to any person or entity of any security similar to the Debenture, shares of Common Stock) which will make unavailable the exemption from Securities Act registration being relied upon by the Company for the offer and sale to Buyer of the Debenture (and the Conversion Shares) as contemplated by this Agreement. No form of general solicitation or advertising has been used or authorized by the Company or any of its officers, directors or Affiliates in connection with the offer or sale of the Debenture (and the Conversion Shares) as contemplated by this Agreement or any other agreement to which the Company is a party.
10. Registration Rights. Except as set forth on Schedule III.M., no Person has, and as of the Closing (as such term is hereinafter defined), no Person shall have, any demand, "piggy-back" or other rights to cause the Company to file any registration statement under the Securities Act relating to any of its securities or to participate in any such registration statement.
11. Interest. The timely payment of interest on the Debenture is not prohibited by the Articles of Incorporation or By-Laws of the Company, in each case as amended to the date of this Agreement, or any agreement, contract, document or other undertaking to which the Company or any of the Subsidiaries is a party.
12. No Misrepresentation. No representation or warranty of the Company contained in this Agreement or any of the other Documents, any schedule, annex or exhibit hereto or thereto or any agreement, instrument or certificate furnished by the Company to Buyer pursuant to this Agreement contains any untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

In connection with any Claim as to which both the Indemnifying Party and the Indemnified Party are parties, the Indemnifying Party shall be entitled to assume the defense thereof. Notwithstanding the assumption of the defense of any Claim by the Indemnifying Party, the Indemnified Party shall have the right to employ separate legal counsel and to participate in the defense of such Claim, and the Indemnifying Party shall bear the reasonable fees, out-of-pocket costs and expenses of such separate legal counsel to the Indemnified Party if (and only if): (x) the Indemnifying Party shall have agreed to pay such fees, out-of-pocket costs and expenses, (y) the Indemnified Party and the Indemnifying Party reasonably shall have concluded that representation of the Indemnified Party and the Indemnifying Party by the same legal counsel would not be appropriate due to actual or, as reasonably determined by legal counsel to the Indemnified Party, potentially differing interests between such parties in the conduct of the defense of such Claim, or if there may be legal defenses available to the Indemnified Party that are in addition to or disparate from those available to the Indemnifying Party or (z) the Indemnifying Party shall have failed to employ legal counsel reasonably satisfactory to the Indemnified Party within a reasonable period of time after notice of the commencement of such Claim. If the Indemnified Party employs separate legal counsel in circumstances other than as described in clauses (x), (y) or (z) above, the fees, costs and expenses of such legal counsel shall be borne exclusively by the Indemnified Party. Except as provided above, the Indemnifying Party shall not, in connection with any Claim in the same jurisdiction, be liable for the fees and expenses of more than one firm of legal counsel for the Indemnified Party (together with appropriate local counsel). The Indemnifying Party shall not, without the prior written consent of the Indemnified Party (which consent shall not unreasonably be withheld), settle or compromise any Claim or consent to the entry of any judgment that does not include an unconditional release of the Indemnified Party from all liabilities with respect to such Claim or judgment.
41. In the event one party hereunder should have a claim for indemnification that does not involve a claim or demand being asserted by a third party, the Indemnified Party promptly shall deliver notice of such claim to the Indemnifying Party. If the Indemnified Party disputes the claim, such dispute shall be resolved by mutual agreement of the Indemnified Party and the Indemnifying Party or by binding arbitration conducted in accordance with the procedures and rules of the American Arbitration Association. Judgment upon any award rendered by any arbitrators may be entered in any court having competent jurisdiction thereof.

NOW, THEREFORE, in consideration of the mutual promises and covenants contained herein, in consideration of LJCI entering into the Agreements, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Guarantor agrees to guaranty the Guarantied Obligations (as hereinafter defined) in accordance with the following terms and conditions:

Guarantor hereby unconditionally and irrevocably guaranties the performance of USData's obligations under the Agreements in favor of LJCI, each of its affiliates, assigns and successors in interest, and each of their respective shareholders, directors, officers, employees, agents, attorneys and representative, arising under or with respect to the Agreements (the "Guarantied Obligations"), when the same shall become due (including amounts that would become due but for the operation of the automatic stay under section 362(a) of the Bankruptcy Code, 11 U.S.C. Subsection 101 et seq.) and agrees to pay any and all costs and expenses (including attorneys' fees and disbursements) incurred by LJCI in enforcing any rights under this Guaranty. In furtherance of the foregoing and not in limitation of any other right which LJCImay have at law or in equity against Guarantor by virtue hereof, upon the failure of USData to perform any of the Guarantied Obligations when and as the same become due, as aforesaid, Guarantor will, within ten (10) days after written demand therefor, perform all Guarantied Obligations then due to LJCI.

Guarantor further agrees that this Guaranty constitutes a guaranty of performance and payment when due and not merely of collection. The obligations of Guarantor under this Guaranty shall not be subject to any reduction, limitation, defense, setoff, recoupment, impairment or termination for any reason, including, without limitation, by reason of the invalidity, illegality or unenforceability of any of the Guarantied Obligations or any discharge of USData from any of the Guarantied Obligations in a bankruptcy or similar proceeding or otherwise. Without limiting the generality of the foregoing, the obligations of Guarantor under this Guaranty shall not be discharged or impaired or otherwise affected by any default, failure or delay or by any other act or thing or omission or delay to do any other act or thing that may or might in any manner or to any extent vary the risk of Guarantor or which would otherwise operate as a discharge of Guarantor as a matter of law or equity. This Guaranty shall remain in full force and effect without regard to any future event, including, without limitation, the bankruptcy, insolvency, reorganization, dissolution or liquidation of USData.

Guarantor agrees that the Guarantied Obligations may be rescinded, waived, extended, renewed or altered, in whole or in part, without notice or further assent from Guarantor, and that Guarantor will remain bound by this Guaranty notwithstanding any such rescission, waiver, extension, renewal or alteration of any Guarantied Obligation.

The obligations of Guarantor under this Guaranty shall not be affected by (i) the failure of LJCI to assert any claim or demand or to enforce any right or remedy against USData under the provisions of the Agreements, including, without limitation, the failure of LJCIto proceed first against USData or to pursue any other remedy in LJCI's power; (ii) LJCI settling, releasing, compromising, collecting or otherwise liquidating the Guarantied Obligations in any manner, as LJCI may determine; (iii) the failure ofLJCIto assert or take advantage of the defense of the statute of limitations in any action hereunder; or (iv) the failure of LJCI to exercise any right or remedy against USData with respect to the Guarantied Obligations or any provision of the Agreements.

Guarantor acknowledges that all of the waivers and consents set forth herein are freely granted, after consultation with competent counsel, since it is Guarantor's purpose and intent that all of Guarantor's obligations hereunder be absolute, independent and unconditional under any and all circumstances. Guarantor hereby represents and warrants to LJCI that Guarantor has the power, right and authority to enter into this Guaranty.
