2.4       Authorization. All corporate action on the part of the Company and its officers, directors and stockholders necessary for the authorization, execution and delivery of this Agreement, the performance of all obligations of the Company hereunder and the authorization, issuance and delivery of the Stock has been taken or will be taken prior to the Initial Closing, and this Agreement, when executed and delivered by the Company, shall constitute the valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms except (a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance, or other laws of general application relating to or affecting the enforcement of creditors’ rights generally, or (b) as limited by laws relating to the availability of specific performance, injunctive relief, or other equitable remedies.

2.5       Valid Issuance of Securities. The Stock, when issued, sold and delivered in accordance with the terms of this Agreement for the consideration expressed herein, will be duly and validly issued, fully paid and nonassessable and free of liens, encumbrances and restrictions on transfer other than restrictions on transfer under this Agreement, applicable state and federal securities laws and liens or encumbrances created by or imposed by a Purchaser.

Assuming the accuracy of the representations made by the Purchasers in Section 3 of this Agreement, no consent, approval, order or authorization of, or registration, qualification, designation, declaration or filing with, any federal, state or local governmental authority is required on the part of the Company in connection with the consummation of the transactions contemplated by this Agreement, except for filings pursuant to Regulation D of the Securities Act, and applicable state securities laws, which have been made or will be made in a timely manner.

2.7       Litigation. There is no claim, action, suit, proceeding, arbitration, complaint, charge or investigation pending or, to the Company’s knowledge, currently threatened against the Company that questions the validity of this Agreement or the right of the Company to enter into it, or to consummate the transactions contemplated hereby, or that would reasonably be expected to cause, either individually or in the aggregate, a Material Adverse Effect. Neither the Company nor, to the Company’s knowledge, any of its officers or directors, is a party or is named as subject to the provisions of any order, writ, injunction, judgment or decree of any court or government agency or instrumentality. There is no action, suit, proceeding or investigation by the Company pending or which the Company intends to initiate. The foregoing includes, without limitation, claims, actions, suits, proceedings or investigations pending or threatened in writing (or any basis therefor known to the Company) involving the prior employment of any of the Company’s employees, their use in connection with the Company’s business, or any information or techniques allegedly proprietary to any of their former employers, or their obligations under any agreements with prior employers.

2.8       Intellectual Property. To the Company’s knowledge, the Company owns or possesses sufficient legal rights to all trademarks, service marks, trade names, domain names, copyrights, trade secrets, licenses, information and proprietary rights and processes and all patents necessary to the conduct of the Company’s business as now conducted and as currently proposed to be conducted, without any conflict with, or infringement of or violation of, the rights of others. Section 2.8 of the Disclosure Schedule contains a complete list of patents and pending patent applications and registrations and applications for trademarks of the Company.

The Company has not received any communications alleging that the Company has violated or, by conducting its business as proposed, would violate any of the patents, trademarks, service marks, trade names, domain names, copyrights, trade secrets or other proprietary rights or processes of any other person or entity, and the Company is not aware of any potential basis for such an allegation or of any reason to believe that such an allegation may be forthcoming. The Company is not aware that any of its employees is obligated under any contract (including licenses, covenants or commitments of any nature) or other agreement, or subject to any judgment, decree or order of any court or administrative agency, that would interfere with the use of such employee’s best efforts to promote the interest of the Company or that would conflict with the Company’s business as now conducted and as currently proposed to be conducted. Neither the execution or delivery or performance of this Agreement, nor the carrying on of the Company’s business by the employees of the Company, nor the conduct of the Company’s business as proposed, will, to the Company’s knowledge, conflict with or result in a breach of the terms, conditions, or provisions of, or constitute a default under, any contract, covenant or instrument under which any such employee is now obligated. The Company does not believe it is or will be necessary to use any inventions of any of its employees made prior to or outside the scope of their employment by the Company.

2.9       Compliance with Other Instruments. The Company is not in violation or default (i) of any provisions of its Articles of Incorporation or Bylaws, or (ii) of any instrument, judgment, order, writ, or decree, or under any note, indenture, mortgage, lease, agreement, contract or purchase order to which it is a party or by which it is bound or, (iii) to its knowledge, of any provision of federal or state statute, rule or regulation applicable to the Company, and with respect to the foregoing subsections (ii) and (iii) only, the violation of which could reasonably be expected to have a Material Adverse Effect. The execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby will not result in any such violation or be in conflict with or constitute, with or without the passage of time and giving of notice, either a default under any such provision, instrument, judgment, order, writ, decree or contract or an event which results in the creation of any lien, charge or encumbrance upon any assets of the Company or the suspension, revocation, impairment, forfeiture or nonrenewal of any material permit, license, authorization or approval applicable to the Company.

By executing this Agreement, the Purchaser further represents that the Purchaser does not presently have any contract, undertaking, agreement or arrangement with any Person to sell, transfer or grant participations to such Person or to any third Person, with respect to any of the Stock. If the Purchaser is a corporation, partnership or other entity, such Purchaser has not been formed for the specific purpose of acquiring the Stock.

The Purchaser has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Stock and the business, properties, prospects and financial condition of the Company. The foregoing, however, does not limit or modify the representations and warranties of the Company in Section 2 of this Agreement or the right of the Purchasers to rely on such representations and warranties.

3.4       Restricted Securities. The Purchaser understands that the Stock will be characterized as “restricted securities” under the federal securities laws, inasmuch as it is being acquired from the Company in a transaction not involving a public offering, and that under such laws and applicable regulations such Stock may not be resold without registration under the Securities Act, except in certain limited circumstances. In this connection, the Purchaser represents that it is familiar with Rule 144 promulgated under the Securities Act, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act. The Purchaser acknowledges that the Company has no obligation to register or qualify the Stock for resale. The Purchaser further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Stock, and on requirements relating to the Company that are outside the Purchaser’s control, and which the Company is under no obligation and may not be able to satisfy.

(b)       Any legend set forth in or required by any other section of this Agreement.

(c)       Any legend required by the securities laws of any state to the extent such laws are applicable to the shares represented by the certificate so legended.

3.7       Accredited Investor. The Purchaser is an accredited investor as defined in Rule 501(a) of Regulation D promulgated under the Securities Act.

3.8       Foreign Investors. If the Purchaser is not a United States person (as defined by Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended), such Purchaser hereby represents that it has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any invitation to subscribe for the Stock or any use of this Agreement, including (a) the legal requirements within its jurisdiction for the purchase of the Stock, (b) any foreign exchange restrictions applicable to such purchase, (c) any governmental or other consents that may need to be obtained, and (d) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, redemption, sale, or transfer of the Stock. Such Purchaser’s subscription and payment for and continued beneficial ownership of the Stock, will not violate any applicable securities or other laws of the Purchaser’s jurisdiction. The funds used to purchase the Stock do not violate the anti-money laundering provisions of the Money Laundering Control Act of 1986 or the Bank Secrecy Act of 1970, as amended by the USA Patriot Act of 2001.

3.10       Exculpation Among Purchasers. The Purchaser acknowledges that it is not relying upon any Person, other than the Company and its officers and directors, in making its investment or decision to invest in the Company. The Purchaser agrees that neither any Purchaser nor the respective controlling persons, officers, directors, partners, members, agents, or employees of any Purchaser shall be liable to any other Purchaser for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the Stock.
