ARTICLE II REPRESENTATIONS AND WARRANTIES 2.1. Representations and Warranties of the Company. The Company ------------------------------------------------- hereby makes the following representations and warranties to the Purchasers: (a) Organization and Qualification. The Company is a ---------------------------------- corporation duly incorporated, validly existing and in good standing under the laws of the State of Utah with the requisite corporate power and authority to own and use its properties and assets and to carry on its business as currently conducted. The Company has no subsidiaries other than as set forth in Schedule -------- 2.1(a) (collectively the "Subsidiaries"). Each of the Subsidiaries is an entity, - ------ duly incorporated or otherwise organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation or organization (as applicable), with the requisite power and authority to own and use its properties and assets and to carry on its business as currently conducted. Each of the Company and the Subsidiaries is duly qualified to do business and is in good standing as a foreign corporation or other entity in each jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary, except where the failure to be so qualified or in good standing, as the case may be, could not, individually or in the aggregate, (x) adversely affect the legality, validity or enforceability of the Securities (as defined below) or any of this Agreement, the Registration Rights Agreement, the Security Agreement, the IP Security Agreement or the Transfer Agent Instructions (collectively, the "Transaction Documents"), (y) have or result in a material adverse effect on the results of operations, assets, prospects, or condition (financial or otherwise) of the Company and the Subsidiaries, taken as a whole, or (z) adversely impair the Company's ability to perform fully on a timely basis its obligations under any of the Transaction Documents (any of (x), (y) or (z), a "Material Adverse Effect"). 3 (b) Authorization; Enforcement. The Company has the requisite --------------------------- corporate power and authority to enter into and to consummate the transactions contemplated by each of the Transaction Documents and otherwise to carry out its obligations thereunder. The execution and delivery of each of the Transaction Documents by the Company and the consummation by it of the transactions contemplated thereby have been duly authorized by all necessary action on the part of the Company and no further action is required by the Company. Each of the Transaction Documents has been duly executed by the Company and, when delivered in accordance with the terms hereof, will constitute the valid and binding obligation of the Company enforceable against the Company in accordance with its terms. Neither the Company nor any Subsidiary is in violation of any of the provisions of its respective certificate or articles of incorporation, by-laws or other organizational or charter documents. (c) Capitalization. The number of authorized, issued and -------------- outstanding capital stock of the Company is set forth in Schedule 2.1(c). No shares of Common Stock are entitled to preemptive or similar rights, nor is any holder of the securities of the Company entitled to preemptive or similar rights arising out of any agreement or understanding with the Company by virtue of any of the Transaction Documents. Except as a result of the purchase and sale of the Debentures and except as disclosed in Schedule 2.1(c), there are no outstanding --------------- options, warrants, script rights to subscribe to, calls or commitments of any character whatsoever relating to, or securities, rights or obligations convertible into or exchangeable for, or giving any Person any right to subscribe for or acquire, any shares of Common Stock, or contracts, commitments, understandings, or arrangements by which the Company or any Subsidiary is or may become bound to issue additional shares of Common Stock, or securities or rights convertible or exchangeable into shares of Common Stock. The issue and sale of the Debentures or Underlying Shares (as hereinafter defined) will not obligate the Company to issue shares of Common Stock or other securities to any person other than the Purchasers (and other than the Initial Investors under the Initial Transaction) and will not result in a right of any holder of Company securities to adjust the exercise or conversion or reset price under such securities. (d) Issuance of the Debentures. When issued, the Debentures --------------------------- will be duly and validly issued, free and clear of all liens, encumbrances and rights of first refusal of any kind (including rights of first refusal under the Initial Transaction which are deemed satisfied with respect to this Agreement) (collectively, "Liens").

Such number of reserved and available shares of Common Stock is not less than the sum of 210% of the number of shares of Common Stock which would be issuable upon conversion in full of the Debentures, assuming such conversion occurred on the Original Issue Date of the Debentures, the Debentures remain outstanding for one year and all interest is paid in shares of Common Stock. All such authorized shares of Common Stock shall be duly reserved for issuance to the holders of the Debentures. The shares of Common Stock issuable upon conversion of the Debentures are collectively referred to herein as the "Underlying Shares." The Debentures and the Underlying Shares are collectively referred to herein as the "Securities." When issued in accordance with the Debentures, the Underlying Shares will be duly authorized, validly issued, fully paid and nonassessable, free and clear of all Liens. 4 (e) No Conflicts.

THESE SECURITIES AND THE SECURITIES ISSUABLE UPON CONVERSION OF THESE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN SECURED BY SUCH SECURITIES. 11 The Company acknowledges and agrees that a Purchaser may from time to time pledge pursuant to a bona fide margin agreement or grant a security interest in some or all of the Securities and, if required under the terms of such arrangement, such Purchaser may transfer pledged or secured Securities to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval of the Company and no legal opinion of the pledgee, secured party or pledgor shall be required in connection therewith. Further, no notice shall be required of such pledge. At the appropriate Purchaser's expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of Securities may reasonably request in connection with a pledge or transfer of the Securities including the preparation and filing of any required prospectus supplement under Rule 424(b)(3) of the Securities Act or other applicable provision of the Securities Act to appropriately amend the list of selling stockholders thereunder. (c) Certificates evidencing Underlying Shares shall not contain the legend set forth above nor any other legend if the conversion of Debentures occurs at any time while an Underlying Shares Registration Statement is effective under the Securities Act or the holder is relying on Rule 144 promulgated under the Securities Act ("Rule 144") in connection with the resale of such Underlying Shares, or in the event there is not an effective Underlying Shares Registration Statement, and Rule 144 is not then available for resale of the Underlying Shares, at such time as such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission). The Company shall cause its counsel to issue the legal opinion included in the Transfer Agent Instructions to the Company's transfer agent on the date that an Underlying Shares Registration Statement is declared effective by the Commission (such date, the "Effective Date"). The Company agrees that following the Effective Date, it will, no later than three (3) Trading Days following the delivery by a Purchaser to the Company of a certificate or certificates representing Underlying Shares issued with a restrictive legend, deliver to such Purchaser certificates representing such Underlying Shares which shall be free from all restrictive and other legends. The Company may not make any notation on its records or give instructions to any transfer agent of the Company which enlarge the restrictions of transfer set forth in this Section. 3.2. Performance of Obligation. The Company acknowledges that the -------------------------- issuance of Underlying Shares upon conversion of the Debentures will result in dilution of the outstanding shares of Common Stock, which dilution may be substantial under certain market conditions. The Company further acknowledges that its obligation to issue Underlying Shares upon conversion of the Debenture is unconditional and absolute, subject to the limitations set forth in the Debentures, regardless of the effect of any such dilution. 12 3.3. Furnishing of Information. As long as the Purchasers own --------------------------- Securities, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Section 13(a) or 15(d) of the Exchange Act. As long as the Purchasers own Securities, if the Company is not required to file reports pursuant to such sections, it will prepare and furnish to the Purchasers and make publicly available in accordance with Rule 144(c) promulgated under the Securities Act such information as is required for the Purchasers to sell the Securities under Rule 144 promulgated under the Securities Act. The Company further covenants that it will take such further action as any holder of Securities may reasonably request, all to the extent required from time to time to enable such Person to sell Underlying Shares without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act, including causing its attorneys to render and deliver any legal opinion required in order to permit a Purchaser to receive Underlying Shares free of all restrictive legends and to subsequently sell Underlying Shares under Rule 144 upon receipt of a notice of an intention to sell or other form of notice having a similar effect. Upon the request of any such Person, the Company shall deliver to such Person a written certification of a duly authorized officer as to whether it has complied with such requirements. 3.4. Integration. The Company shall not, and shall use its best ----------- efforts to ensure that, no Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities to the Purchasers. 3.5. Increase in Authorized Shares. If on any date the Company would ------------------------------ be, if a notice of conversion were to be delivered on such date, precluded from issuing 210% of the number of Underlying Shares as would then be issuable upon a conversion in full of the Debentures (the "Current Required Minimum"), in either case, due to the unavailability of a sufficient number of authorized but unissued or reserved shares of Common Stock, then the Board of Directors of the Company shall promptly (and in any case, within 30 Business Days from such date) prepare and mail to the stockholders of the Company proxy materials requesting authorization to amend the Company's certificate or articles of incorporation to increase the number of shares of Common Stock which the Company is authorized to issue to at least such number of shares as reasonably requested by the Purchasers in order to provide for such number of authorized and unissued shares of Common Stock to enable the Company to comply with its issuance, conversion and reservation of shares obligations as set forth in this Agreement and the Debentures. The sum of (x) the number of shares of Common Stock then outstanding plus all shares of Common Stock issuable upon exercise of all outstanding options, warrants and convertible instruments, and (y) the Current Required Minimum, shall be a reasonable number. In connection therewith, the Board of Directors shall (a) adopt proper resolutions authorizing such increase, (b) recommend to and otherwise use its best efforts to promptly and duly obtain stockholder approval to carry out such resolutions (and hold a special meeting of the stockholders no later than the earlier to occur of the 60th day after delivery of the proxy materials relating to such meeting and the 90th day after request by a holder of Securities to issue the number of Underlying Shares in accordance with the terms hereof) and (c) within five Business Days of obtaining such stockholder authorization, file an appropriate amendment to the Company's certificate or articles of incorporation to evidence such increase. Any failure to amend the Company's Certificate or Articles of Incorporation by the 90th day following request thereof or date otherwise required shall be a breach of this provision, even if the Company shall have complied with each other requirement of this paragraph. 13 3.6. Reservation and Listing of Underlying Shares. (a) The Company ---------------------------------------------- shall: (i) in the time and manner required by any national securities exchange, market, trading or quotation facility on which the Common Stock is then traded, prepare and file with such national securities exchange, market, trading or quotation facility on which the Common Stock is then traded an additional shares listing application covering a number of shares of Common Stock which is not less than the Initial Minimum, (ii) take all steps necessary to cause such shares of Common Stock to be approved for listing on any such national securities exchange, market or trading or quotation facility on which the Common Stock is then listed as soon as possible thereafter, and (iii) provide to the Purchasers evidence of such listing, and the Company shall maintain the listing of its Common Stock thereon. If the number of Underlying Shares issuable upon conversion in full of the then outstanding Debentures exceeds 85% of the number of Underlying Shares previously listed on account thereof with any such required exchanges, then the Company shall take the necessary actions to immediately list a number of Underlying Shares as equals no less than the then Current Required Minimum. (b) The Company shall maintain a reserve of shares of Common Stock for issuance upon conversion of the Debentures in full in accordance with this Agreement, in such amount as may be required to fulfill its obligations in full under the Transaction Documents, which reserve shall equal no less than the then Current Required Minimum. 3.7. Conversion Procedures. The Transfer Agent Instructions and ---------------------- Conversion Notice (as defined in the Debentures) set forth the totality of the procedures with respect to the conversion of the Debentures, including the form of legal opinion, if necessary, that shall be rendered to the Company's transfer agent and such other information and instructions as may be reasonably necessary to enable the Purchasers to convert their Debentures. 3.8. Conversion Obligations of the Company. The Company shall honor -------------------------------------- conversions of the Debentures and shall deliver Underlying Shares in accordance with the respective terms, conditions and time periods set forth in the Debentures . 3.9. Subsequent Financing; Limitation on Registrations. (a) Subject -------------------------------------------------- to Section 3.9(c) and (d), from the date hereof through the 90th Trading Day following the Effective Date, the Company will not: (i) offer, sell, grant any option to purchase, or otherwise dispose of (or announce any offer, sale, grant or any option to purchase or other disposition) any of its or its Affiliates' equity or equity equivalent securities (including the issuance of any debt or other instrument at any time over the life thereof convertible into or exchangeable for Common Stock (any such offer, sale, grant, disposition or announcement being referred to as a "Subsequent Placement") or (ii) file a registration statement (other than on a Form S-8 and pursuant to the Registration Rights Agreement) with the Commission with respect to any securities of the Company. 14 (b) Subject to Section 3.9(c) and (d), from the date hereof until the expiration of the 180th Trading Day after the Effective Date, the Company shall not, directly or indirectly, effect any Susequent Placement unless: (i) the Company delivers to each of the Purchasers a written notice (the "Subsequent Placement Notice") of its intention to effect such Subsequent Placement, which Subsequent Placement Notice shall describe in reasonable detail the proposed terms of such Subsequent Placement, the amount of proceeds intended to be raised thereunder, the Person with whom such Subsequent Placement shall be effected, and attached to which shall be a term sheet or similar document relating thereto and (ii) such Purchaser shall not have notified the Company by 6:30 p.m. (New York City time) on the tenth Trading Day after its receipt of the Subsequent Placement Notice of its willingness to provide (or to cause its sole designee to provide), subject to completion of mutually acceptable documentation, financing to the Company on the same terms set forth in the Subsequent Placement Notice. If the Purchasers shall fail to notify the Company of their intention to enter into such negotiations within such time period, the Company may effect the Subsequent Placement substantially upon the terms and to the Persons (or Affiliates of such Persons) set forth in the Subsequent Placement Notice; provided, that the Company shall provide the Purchasers with a second Subsequent Placement Notice, and the Purchasers shall again have the right of first refusal set forth above in this paragraph (a), if the Subsequent Placement subject to the initial Subsequent Placement Notice shall not have been consummated for any reason on the terms set forth in such Subsequent Placement Notice within 45 Trading Days after the date of the initial Subsequent Placement Notice with the Person (or an Affiliate of such Person) identified in the Subsequent Placement Notice. If the Purchasers shall indicate a willingness to provide financing in excess of the amount set forth in the Subsequent Placement Notice, then each Purchaser shall be entitled to provide financing pursuant to such Subsequent Placement Notice up to an amount equal to such Purchaser's pro-rata portion of the aggregate number of Shares purchased by such Purchaser under this Agreement, but the Company shall not be required to accept financing from the Purchasers in an amount in excess of the amount set forth in the Subsequent Placement Notice. (c) The restrictive periods set forth in Section 3.9(a) and (b), shall be extended for the number of Trading Days during such periods in which: (i) trading in the Common Stock is suspended by any securities exchange or market or quotation system on which the Common Stock is then listed, or (ii) the Underlying Shares Registration Statement is not effective, or (iii) the prospectus included in the Underlying Shares Registration Statement may not be used by the Purchasers for the resale of Registrable Securities thereunder. (d) The restrictions contained in Section 3.9(a)(i) and (b) above, shall not apply to: (i) the granting of options or warrants to employees, officers and directors of the Company, and the issuance of Common Stock upon exercise of such options or warrants granted under any stock option plan heretofore or hereinafter duly adopted by the Company, (ii) issuances of Common Stock pursuant to a Strategic Transaction (as defined herein) and (iii) issuances of Common Stock to the Initial Investors pursuant to the Initial Transaction. A "Strategic Transaction" shall mean a transaction or relationship in which the Company issues shares of Common Stock to a Person which is, itself or through its subsidiaries, an operating company in a business related to the business of the Company and in which the Company receives material benefits in addition to the investment of funds, but shall not include a transaction in which the Company is issuing securities primarily for the purpose of raising capital or to an entity whose primary business is investing in securities. 15 3.10.

Notwithstanding the foregoing, the Company shall not publicly disclose the names of the Purchasers, or include the names of the Purchasers in any filing with the Commission, or any regulatory agency, trading facility or stock market without the prior written consent of the Purchasers, except to the extent such disclosure (but not any disclosure as to the controlling Persons thereof) is required by law or stock market regulations, in which case the Company shall provide the Purchasers with prior notice of such disclosure. 3.11. Transfer of Intellectual Property Rights. Except in connection ----------------------------------------- with the sale of all or substantially all of the assets of the Company or licensing arrangements in the ordinary course of the Company's business, the Company shall not transfer, sell or otherwise dispose of any Intellectual Property Rights, or allow any of the Intellectual Property Rights to become subject to any Liens, or fail to renew such Intellectual Property Rights (if renewable and it would otherwise lapse if not renewed), without the prior written consent of the Purchasers. 3.12. Use of Proceeds. The Company shall use the net proceeds from the --------------- sale of the Securities hereunder for working capital purposes and not for the satisfaction of any portion of the Company's debt (other than payment of trade payables in the ordinary course of the Company's business and prior practices), to redeem any Company equity or equity-equivalent securities or to settle any outstanding litigation. 3.13. Reimbursement. If any Purchaser becomes involved in any capacity ------------- in any action, proceeding or investigation brought by or against any Person, including stockholders of the Company, solely as a result of acquiring the Securities under this Agreement, the Company will reimburse such Purchaser for its reasonable legal and other expenses (including the cost of any investigation, preparation and travel in connection therewith) incurred in connection therewith, as such expenses are incurred. The reimbursement obligations of the Company under this paragraph shall be in addition to any liability which the Company may otherwise have, shall extend upon the same terms and conditions to any Affiliates of the Purchasers who are actually named in such action, proceeding or investigation, and partners, directors, agents, employees and controlling persons (if any), as the case may be, of the Purchasers and any such Affiliate, and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Company, the Purchasers and any such Affiliate and any such Person. The Company also agrees that neither the Purchasers nor any such Affiliates, partners, directors, agents, employees or controlling persons shall have any liability to the Company or any Person asserting claims on behalf of or in right of the Company solely as a result of acquiring the Securities under this Agreement. The Company's reimbursement obligation under this Section shall not apply if any action, proceeding or investigation arises out of or relates to any Purchaser's gross negligence or willful misconduct. 16 3.14. Shareholders Rights Plan. No claim will be made or enforced by ------------------------- the Company or any other Person that any Purchaser is an "Acquiring Person" under any shareholders rights plan or similar plan or arrangement in effect or hereafter adopted by the Company, or that any Purchaser could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving Securities under the Transaction Documents or under any other agreement between the Company and the Purchasers.
