All of the Material Contracts are valid, binding and in full force and effect in all material respects, subject to laws of general application relating to bankruptcy, insolvency and the relief of debtors and rules of law governing specific performance, injunctive relief or other equitable remedies and to general principles of equity. Neither the Company is nor is any other party to the Material Contracts in material default under any of such Material Contracts.

(D) Intellectual Property.

(a) Ownership. Except as disclosed in the SEC Reports, to the knowledge of the Company (without having conducted any special investigation or patent search), the Company owns or possesses or can obtain on commercially reasonable terms sufficient legal rights to all patents, trademarks, service marks, trade names, copyrights, trade secrets, licenses, information, processes and similar proprietary rights (“Intellectual Property”) necessary to the business of the Company as presently conducted, the lack of which could reasonably be expected to have (i) a material adverse effect on the legality, validity or enforceability of this Agreement, (ii) a material adverse effect on the results of operations, assets, business, prospects or condition (financial or otherwise) of the Company or (iii) a material adverse effect on the Company’s ability to perform in any material respect on a timely basis its obligations under this Agreement (any of (i), (ii) or (iii), a “Material Adverse Effect”). The Company has not received any written communication alleging that the Company has violated or, by conducting its business as currently conducted, would violate any of the Intellectual Property of any other person or entity , nor is the Company aware of any basis therefor.

(b) No Breach by Employees. Except as disclosed in the SEC Reports, the Company is not aware that any of its employees is obligated under any contract or other agreement, or subject to any judgment, decree or order of any court or administrative agency, that would materially interfere with the use of his or her efforts to promote the interests of the Company or that would conflict with the Company’s business as presently conducted. Neither the execution nor delivery 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 presently conducted, 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 of such employees 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 their employment by the Company.

(E) Title to Properties and Assets; Liens. Except as disclosed in the SEC Reports, to the knowledge of the Company, the Company has good and marketable title to its properties and assets, and has good title to all its leasehold interests, in each case subject to no material mortgage, pledge, lien, lease, encumbrance or charge, other than (i) liens for current taxes not yet due and payable, (ii) liens imposed by law and incurred in the ordinary course of business for obligations not past due, (iii) liens in respect of pledges or deposits under workers’ compensation laws or similar legislation, and (iv) liens, encumbrances and defects in title which do not in any case materially detract from the value of the property subject thereto or have a Material Adverse Effect, and which have not arisen otherwise than in the ordinary course of business. With respect to the property and assets it leases, the Company is in compliance with such leases in all material respects and, to its knowledge, holds a valid leasehold interest free of any liens, claims or encumbrances, subject to clauses (i)-(iv) above.

(F) Compliance with Other Instruments. The Company is not in violation of any material term of its Certificate of Incorporation or bylaws, each as amended to date, or, to the Company’s knowledge, in any material respect of any term or provision of any material mortgage, indebtedness, indenture, contract, agreement, instrument, judgment, order or decree to which it is party or by which it is bound which would have a Material Adverse Effect. To the Company’s knowledge, the Company is not in violation of any federal or state statute, rule or regulation applicable to the Company the violation of which would have a Material Adverse Effect. The execution and delivery of the Agreement by the Company, the performance by the Company of its obligations pursuant to the Agreement, and the issuance of the Securities will not result in any material violation of, or materially conflict with, or constitute a material default under, the Company’s Certificate of Incorporation or bylaws, each as amended to date, or any of its agreements, nor, to the Company’s knowledge, result in the creation of any material mortgage, pledge, lien, encumbrance or charge upon any of the properties or assets of the Company.

(G) Litigation. Except as disclosed in the SEC Reports, there are no actions, suits, proceedings or investigations pending against the Company or its properties (nor has the Company received notice of any threat thereof) before any court or governmental agency.

There is no action, suit or proceeding initiated by the Company currently pending.

(H) Permits. The Company has all franchises, permits, licenses, and any similar authority necessary for the conduct of its business as now being conducted by it, the lack of which would have a Material Adverse Effect, and believes it can obtain, without undue burden or expense, any similar authority for the conduct of its business as presently planned to be conducted. The Company is not in default in any material respect under any of such franchises, permits, licenses or other similar authority.

(I) Offering. Subject to the accuracy of the Subscriber’s representations and warranties, the offer, sale and issuance of the Securities to be issued in conformity with the terms of this Agreement constitute transactions exempt from the registration requirements of the Securities Act and, except

for such notice requirements as may arise under applicable state law, from the registration or qualification requirements of applicable state securities laws, and neither the Company nor any authorized agent acting on its behalf will take any action hereafter that would cause the loss of such exemption.

(J) Tax Returns and Payments. The Company has timely filed all tax returns required to be filed by it with appropriate federal, state and local governmental agencies, except where the failure to do so would not have a Material Adverse Effect. These returns and reports are true and correct in all material respects.
