D.                                    For purposes of this Agreement: “Conversion Shares” means all shares of Common Stock issuable upon conversion or redemption of all or any portion of the Note; and “Securities” means the Note and the Conversion Shares.

NOW, THEREFORE, in consideration of the above recitals and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Company and Investor hereby agree as follows:

1.                                      Purchase and Sale of Securities.

1.1.                            Purchase of Securities. Company shall issue and sell to Investor and Investor agrees to purchase from Company the Note. In consideration thereof, Investor shall pay the Purchase Price (as defined below) to Company.

If Investor and Company are unable to agree upon such Calculation within two (2) Trading Days of such disputed Calculation being submitted to Company or Investor (as the case may be), then Investor will promptly submit via email or facsimile the disputed Calculation to Unkar Systems Inc. (“Unkar Systems”).

8.7.                            Document Imaging. Investor shall be entitled, in its sole discretion, to image or make copies of all or any selection of the agreements, instruments, documents, and items and records governing, arising from or relating to any of Company’s loans, including, without limitation, this Agreement and the other Transaction Documents, and Investor may destroy or archive the paper originals. The parties hereto (i) waive any right to insist or require that Investor produce paper originals, (ii) agree that such images shall be accorded the same force and effect as the paper originals, (iii) agree that Investor is entitled to use such images in lieu of destroyed or archived originals for any purpose, including as admissible evidence in any demand, presentment or other proceedings, and (iv) further agree that any executed facsimile (faxed), scanned, emailed, or other imaged copy of this Agreement or any other Transaction Document shall be deemed to be of the same force and effect as the original manually executed document.

8.8.                            Headings. The headings of this Agreement are for convenience of reference only and shall not form part of, or affect the interpretation of, this Agreement.

8.9.                            Severability. In the event that any provision of this Agreement is invalid or unenforceable under any applicable statute or rule of law, then such provision shall be deemed inoperative to the extent that it may conflict therewith and shall be deemed modified to conform to such statute or rule of law. Any provision hereof which may prove invalid or unenforceable under any law shall not affect the validity or enforceability of any other provision hereof.

8.10.                     Entire Agreement. This Agreement, together with the other Transaction Documents, contains the entire understanding of the parties with respect to the matters covered herein and therein and, except as specifically set forth herein or therein, neither Company nor Investor makes any

representation, warranty, covenant or undertaking with respect to such matters. For the avoidance of doubt, all prior term sheets or other documents between Company and Investor, or any affiliate thereof, related to the transactions contemplated by the Transaction Documents (collectively, “Prior Agreements”), that may have been entered into between Company and Investor, or any affiliate thereof, are hereby null and void and deemed to be replaced in their entirety by the Transaction Documents. To the extent there is a conflict between any term set forth in any Prior Agreement and the term(s) of the Transaction Documents, the Transaction Documents shall govern.

8.11.                     No Reliance. Company acknowledges and agrees that neither Investor nor any of its officers, directors, members, managers, representatives or agents has made any representations or warranties to Company or any of its officers, directors, representatives, agents or employees except as expressly set forth in the Transaction Documents and, in making its decision to enter into the transactions contemplated by the Transaction Documents, Company is not relying on any representation, warranty, covenant or promise of Investor or its officers, directors, members, managers, agents or representatives other than as set forth in the Transaction Documents.

8.12.                     Amendments. No provision of this Agreement may be waived or amended other than by an instrument in writing signed by both parties hereto.

8.13.                     Notices.

8.14.                     Successors and Assigns. This Agreement or any of the severable rights and obligations inuring to the benefit of or to be performed by Investor hereunder may be assigned by Investor to a third party, including its affiliates, in whole or in part, without the need to obtain Company’s consent thereto. Company may not assign its rights or obligations under this Agreement or delegate its duties hereunder without the prior written consent of Investor.

8.15.                     Survival. The representations and warranties of Company and the agreements and covenants set forth in this Agreement shall survive the Closing hereunder notwithstanding any due diligence investigation conducted by or on behalf of Investor. Company agrees to indemnify and hold harmless Investor and all its officers, directors, employees, attorneys, and agents for loss or damage arising as a result of or related to any breach or alleged breach by Company of any of its representations, warranties and covenants set forth in this Agreement or any of its covenants and obligations under this Agreement, including advancement of expenses as they are incurred.

8.16.                     Further Assurances. Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as the other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

8.17.                     Investor’s Rights and Remedies Cumulative; Liquidated Damages. All rights, remedies, and powers conferred in this Agreement and the Transaction Documents are cumulative and not exclusive of any other rights or remedies, and shall be in addition to every other right, power, and remedy that Investor may have, whether specifically granted in this Agreement or any other Transaction Document, or existing at law, in equity, or by statute, and any and all such rights and remedies may be exercised from time to time and as often and in such order as Investor may deem expedient. The parties acknowledge and agree that upon Company’s failure to comply with the provisions of the Transaction Documents, Investor’s damages would be uncertain and difficult (if not impossible) to accurately estimate because of the parties’ inability to predict future interest rates and future share prices, Investor’s increased risk, and the uncertainty of the availability of a suitable substitute investment opportunity for Investor, among other reasons. Accordingly, any fees, charges, and default interest due under the Note and the other Transaction Documents are intended by the parties to be, and shall be deemed, liquidated damages (under Company’s and Investor’s expectations that any such liquidated damages will tack back to the Closing Date for purposes of determining the holding period under Rule 144 under the 1933 Act). The parties agree that such liquidated damages are a reasonable estimate of Investor’s actual damages and not a penalty, and shall not be deemed in any way to limit any other right or remedy Investor may have hereunder, at law or in equity. The parties acknowledge and agree that under the circumstances existing at the time this Agreement is entered into, such liquidated damages are fair and reasonable and are not penalties. All fees, charges, and default interest provided for in the Transaction Documents are agreed to by the parties to be based upon the obligations and the risks assumed by the parties as of the Closing Date and are consistent with investments of this type. The liquidated damages provisions of the Transaction Documents shall not limit or preclude a party from pursuing any other remedy available at law or in equity; provided, however, that the liquidated damages provided for in the Transaction Documents are intended to be in lieu of actual damages.

8.18.                     Ownership Limitation. Notwithstanding anything to the contrary contained in this Agreement or the other Transaction Documents, if at any time Investor would be issued shares of Common Stock under any of the Transaction Documents, but such issuance would cause Investor (together with its affiliates) to beneficially own a number of shares exceeding the Maximum Percentage (as defined in the Note), then Company must not issue to Investor the shares that would cause Investor to exceed the Maximum Percentage. The shares of Common Stock issuable to Investor that would cause the Maximum Percentage to be exceeded are referred to herein as the “Ownership Limitation Shares”. Company shall reserve the Ownership Limitation Shares for the exclusive benefit of Investor. From time to time, Investor may notify Company in writing of the number of the Ownership Limitation Shares that may be issued to Investor without causing Investor to exceed the Maximum Percentage. Upon receipt of such notice, Company shall be unconditionally obligated to immediately issue such designated shares to Investor, with a corresponding reduction in the number of the Ownership Limitation Shares. For purposes of this Section, beneficial ownership of Common Stock will be determined under Section 13(d) of the 1934 Act.

8.19.                     Attorneys’ Fees and Cost of Collection. In the event of any arbitration or action at law or in equity to enforce or interpret the terms of this Agreement or any of the other Transaction Documents, the parties agree that the party who is awarded the most money (which, for the avoidance of doubt, shall be determined without regard to any statutory fines, penalties, fees, or other charges awarded to any party) shall be deemed the prevailing party for all purposes and shall therefore be entitled to an additional award of the full amount of the reasonable and documented out-of-pocket attorneys’ fees, deposition costs, and expenses paid by such prevailing party in connection with arbitration or litigation without reduction or apportionment based upon the individual claims or defenses giving rise to the fees and expenses. Nothing herein shall restrict or impair an arbitrator’s or a court’s power to award fees and expenses for frivolous or bad faith pleading. If (i) the Note is placed in the hands of an attorney for collection or enforcement prior to commencing arbitration or legal proceedings, or is collected or enforced through any arbitration or legal proceeding, or Investor otherwise takes action to collect amounts due under the Note or to enforce the provisions of the Note, or (ii) there occurs any bankruptcy, reorganization, receivership of Company or other proceedings affecting Company’s creditors’ rights and involving a claim under the Note; then Company shall pay the costs incurred by Investor for such collection, enforcement or action or in connection with such bankruptcy, reorganization, receivership or other proceeding, including, without limitation, attorneys’ fees, expenses, deposition costs, and disbursements.

8.20.                     Waiver. No waiver of any provision of this Agreement shall be effective unless it is in the form of a writing signed by the party granting the waiver. No waiver of any provision or consent to any prohibited action shall constitute a waiver of any other provision or consent to any other prohibited action, whether or not similar. No waiver or consent shall constitute a continuing waiver or consent or commit a party to provide a waiver or consent in the future except to the extent specifically set forth in writing.

8.21.                     Waiver of Jury Trial. EACH PARTY TO THIS AGREEMENT IRREVOCABLY WAIVES ANY AND ALL RIGHTS SUCH PARTY MAY HAVE TO DEMAND THAT ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR IN ANY WAY RELATED TO THIS AGREEMENT, ANY OTHER TRANSACTION DOCUMENT, OR THE RELATIONSHIPS OF THE PARTIES HERETO BE TRIED BY JURY. THIS WAIVER EXTENDS TO ANY AND ALL RIGHTS TO DEMAND A TRIAL BY JURY ARISING UNDER COMMON LAW OR ANY APPLICABLE STATUTE, LAW, RULE OR REGULATION. FURTHER, EACH PARTY HERETO ACKNOWLEDGES THAT SUCH

12

PARTY IS KNOWINGLY AND VOLUNTARILY WAIVING SUCH PARTY’S RIGHT TO DEMAND TRIAL BY JURY.

8.22.                     Time is of the Essence. Time is expressly made of the essence with respect to each and every provision of this Agreement and the other Transaction Documents.

8.23.                     Voluntary Agreement. Company has carefully read this Agreement and each of the other Transaction Documents and has asked any questions needed for Company to understand the terms, consequences and binding effect of this Agreement and each of the other Transaction Documents and fully understand them. Company has had the opportunity to seek the advice of an attorney of Company’s choosing, or has waived the right to do so, and is executing this Agreement and each of the other Transaction Documents voluntarily and without any duress or undue influence by Investor or anyone else.
