2. Issuance.

The Issuer represents and warrants that, on the Issuance Date, the Issuer delivered to Subscriber (1) the Acquired Shares in book entry form, free and clear of any liens, encumbrances or other restrictions whatsoever (other than those arising under state or federal securities laws or imposed by Subscriber), in the name of Subscriber (or its nominee in accordance with its delivery instructions) or to a custodian designated by Subscriber, as applicable, and (2) a copy of the records of the transfer agent of the Issuer (the “Transfer Agent”) showing Subscriber as the owner of the Acquired Shares on and as of the Issuance Date (the “Subscriber’s Deliveries”).

3. Issuer Representations and Warranties. The Issuer represents and warrants to Subscriber as of the Issuance Date and as of the date of this Agreement that:

(a)

The Issuer and each of its subsidiaries is duly incorporated or formed (as applicable), validly existing and in good standing under the laws of the jurisdiction of its incorporation or formation (as applicable), with all corporate, limited liability company, partnership or other entity power and authority to own, lease and operate its properties and conduct its business as presently conducted and, with respect to the Issuer, to enter into, deliver and perform its obligations under this Subscription Agreement. Except where such noncompliance would not reasonably be expected to constitute an Issuer Material Adverse Effect, the Issuer and each of its subsidiaries is duly qualified to do business as a foreign corporation and, to the extent applicable, in good standing, in all other jurisdictions where the ownership or leasing of its properties or the conduct of its business required such qualification. For purposes of this Subscription Agreement, an “Issuer Material Adverse Effect” means an event, change, development, occurrence, condition or effect with respect to the Issuer and its subsidiaries and affiliates, taken together as a whole (on a consolidated basis), that, would reasonably be expected to have a material adverse effect on the business, financial condition, assets, liabilities or results of operations of the Issuer and its subsidiaries, taken together as a whole (on a consolidated basis) or the Issuer’s ability to consummate the transactions contemplated by this Subscription Agreement, including the issuance and sale of the Acquired Shares.

(b)

The Acquired Shares have been duly authorized, validly issued, fully paid and are non-assessable and free and clear of all liens, encumbrances or other restrictions (except as otherwise stated herein) and have not been issued in violation of or subject to any preemptive or similar rights created under the Issuer’s certificate of incorporation and bylaws (each, as amended) or under the laws of the State of Nevada or otherwise.

This Subscription Agreement has been duly authorized, executed and delivered by the Issuer and, assuming that this Subscription Agreement constitutes the valid and binding agreement of Subscriber, this Subscription Agreement is enforceable against the Issuer in accordance with its terms, except as may be limited or otherwise affected by (i) bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other laws relating to or affecting the rights of creditors generally, and (ii) principles of equity, whether considered at law or equity.

(d)

The execution, delivery and performance of this Subscription Agreement, including the issuance and sale of the Acquired Shares by the Issuer, do not and will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of the Issuer pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which the Issuer (or any of its subsidiaries or affiliates) is a party or by which the Issuer (or any of its subsidiaries or affiliates) is bound or to which any of the property or assets of the Issuer (or any of its subsidiaries or affiliates) is subject; (ii) the organizational documents of the Issuer (or any of its subsidiaries or affiliates); or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency, taxing authority or regulatory body, domestic or foreign, having jurisdiction over the Issuer or any of its properties, which would reasonably be expected to have an Issuer Material Adverse Effect.

(f)

The Issuer is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority, self-regulatory organization or other Person in connection with the execution, delivery and performance by the Issuer of this Subscription Agreement (including, without limitation, the issuance of the Acquired Shares), other than, as applicable, (i) the filing with the Commission of the Registration Statement (as defined below); (ii) filings required by applicable state securities laws; (iii) those required by Nasdaq; (iv) any filing, the failure of which to obtain would not reasonably be expected to have, individually or in the aggregate, an Issuer Material Adverse Effect and (v) the filing of a Notice of Exempt Offering of Securities on Form D with the Commission under Regulation D of the Securities Act.

To the extent permitted under Nasdaq rules, the Issuer hereby grants to Subscriber the right to purchase its Pro Rata Portion of any Equity Securities (other than any Excluded Securities) that the Issuer (or any of its subsidiaries) may from time to time propose to issue or sell to any Person. To the extent stockholder approval is required under the Nasdaq rules for the issuance or sale of Equity Securities as provided in this Section 5 the Issuer may issue or sell Equity Securities to such other Persons prior to obtaining such stockholder approval; provided that the Issuer shall use its reasonable best efforts to obtain such approval; and provided further that, after receipt of such stockholder approval, the Issuer shall issue or sell the Equity Securities (if any) that Subscriber has irrevocably elected to purchase to Subscriber, on the terms set forth in the relevant Issuance Notice. For purposes of this Subscription Agreement, (A) “Equity Securities” means (i) any common stock issued by the Issuer or any of its subsidiaries, (ii) any preferred stock of the Issuer or any of its subsidiaries, and (iii) any securities convertible into or exchangeable for, or options, warrants or other rights to acquire, common or preferred stock issued by the Issuer or any of its subsidiaries, (B) “Excluded Securities” means Equity Securities issued in connection with: (i) a grant to any existing or prospective consultants, employees, officers or directors pursuant to any stock option, employee stock purchase or similar equity-based plans or other compensation agreement; (ii) any acquisition by the Issuer or any of its subsidiaries of the stock, assets, properties or business of any Person; (iii) a stock split, stock dividend or any similar recapitalization; or (iv) any issuance of warrants or other similar rights to purchase Issuer Common Stock to lenders or other institutional investors in any arm’s length transaction providing debt financing to the Issuer or any of its subsidiaries, and (C) “Pro Rata Portion” means, with respect to Subscriber, on any issuance date for Equity Securities, the number of Equity Securities equal to the product of (i) the total number of Equity Securities to be issued by the Issuer or any of its subsidiaries on such date and (ii) the fraction determined by dividing (x) the number of shares of Common Stock of the Issuer owned by Subscriber immediately prior to such issuance by (y) the total number of shares of Common Stock of the Issuer outstanding on such date immediately prior to such issuance.

(b)

The Issuer shall give written notice (an “Issuance Notice”) of any proposed issuance or sale described in Section 5(a) to Subscriber within five (5) business days following any meeting of the Issuer’s Board of Directors (or similar governing body of the applicable subsidiary) at which any such issuance or sale is approved or, if the approval of the Issuer’s Board of Directors (or similar governing body of the applicable subsidiary) is not required in connection with such issuance or sale, no less than ten (10) business days prior to the date of the proposed issuance or sale. The Issuance Notice shall, if applicable, be accompanied by a written offer from any prospective purchaser seeking to purchase Equity Securities (subject to any obligations of confidentiality with such prospective purchaser that would prevent disclosure of such written offer; provided that the Issuer shall provide to United a redacted copy of such offer to the extent permissible under the terms of such confidentiality agreement and shall use commercially reasonable efforts to seek a waiver and consent from the applicable person to share such offer with United) and shall set forth the material terms and conditions of the proposed issuance, including:

(i) the number and class of the Equity Securities to be issued and the percentage of the outstanding shares of capital stock of the Issuer such issuance would represent;

(ii) the proposed issuance date, which shall be at least ten (10) business days from the date of the Issuance Notice; and

Subscriber shall for a period of ten (10) Business Days following the receipt of an Issuance Notice have the right to elect irrevocably to purchase its Pro Rata Portion of the Equity Securities at the purchase price set forth in the Issuance Notice by delivering a written notice to the Issuer. If, at the termination of such ten (10) business day period, Subscriber shall not have delivered such notice to the Issuer, Subscriber shall be deemed to have waived all of its rights under this Section 5 with respect to the purchase of such Equity Securities. The closing of any purchase by Subscriber shall be consummated concurrently with the consummation of the issuance or sale described in the Issuance Notice; provided, however, that the closing of any purchase by Subscriber may be extended beyond the closing of the transaction in the Issuance Notice to the extent necessary to obtain any required approval or consent of a governmental authority or any other third party (and the Issuer and Subscriber shall use their respective reasonable best efforts to obtain such approvals).

(d)

Upon the expiration of the ten (10) business day period described in Section 5(c), the Issuer (or its subsidiary) shall be free, for a period of ninety (90) days, to sell such Equity Securities that Subscriber has not elected irrevocably to purchase on terms and conditions no more favorable to the purchasers thereof than those offered to Subscriber in the Issuance Notice delivered in accordance with Section 5(c). If the proposed sale is not so consummated within such ninety (90) days period, the Equity Securities proposed to be sold may not be sold unless the Issuer again complies with this Section 5.
