On the Conversion Date, Borrower will immediately execute and deliver the Subordinate Note(s) and the Warrant(s) to the applicable Noteholder(s), and the holder of any Convertible Subordinated Note shall deliver such Convertible Subordinated Note to the Borrower to be canceled and of no further force or effect.

Section 2.3.           Use of Proceeds. Borrower agrees to use the full proceeds of the Convertible Subordinated Notes to consummate the transactions contemplated in the Merger Documents and the Investment Documents.

Section 2.4.           Payments and Endorsements.

(a)                                       Payments of principal, interest and premium, if any, on the Notes shall be made without set off or counterclaim, directly by wire transfer to an account designated in writing by each Noteholder, without any presentment or notation of payment, except that prior to any transfer of any Note, the holder thereof shall endorse on such Note a record of the date to which interest has been paid and all payments made on account of principal of such Note. All payments and prepayments of principal of, and interest on, the Notes shall be applied (to the extent thereof) to all of the Notes pro rata based on the principal amount outstanding and held by each holder thereof.

(b)                                      Anything herein to the contrary notwithstanding, if any changes in present or future Applicable Law shall impose on Borrower any obligation with respect to any amount payable by it hereunder or under any of the other Related Agreements to withhold or deduct any taxes, levies, imposts, duties, charges, fees, deductions or withholdings, Borrower will pay to the Noteholders, on the date on which such amount is due and payable hereunder or under such other Related Agreements, such additional amount in United States dollars as shall be necessary to enable the Noteholders to receive the same net amount which the Noteholders would have received on such due date if no such obligation had been imposed upon Borrower.

(c)                                       The obligations of Borrower under this Section 2.4 shall survive the payment in full of all amounts due hereunder or under the Notes.

Section 2.5.           Redemptions and Mandatory Repurchase.

2.5.1        Required Redemption. On the stated or accelerated maturity of the Notes, Borrower will pay the principal amount of the Notes then outstanding together with all accrued and unpaid interest thereon. No redemption of less than all of the Notes shall affect the obligation of Borrower to make the redemption required by this sub-Section.

2.5.2        Optional Redemptions. In addition to the redemption of the Notes required under sub-Section 2.5.1, Borrower may, at any time, voluntarily redeem the Notes, in whole or in part (in integral multiples of Five Hundred Thousand Dollars ($500,000)), together with all accrued and unpaid interest on the amount so redeemed through the date of redemption, at a redemption price equal to:

(a)             if such voluntary redemption, including a redemption pursuant to sub-Section 2.5.4, occurs on or prior to the first anniversary of the date of this Agreement, one hundred six percent (106%) of the sum of the principal amount to be redeemed plus any accrued but unpaid interest thereon;

(b)             if such voluntary redemption, including a redemption pursuant to sub-Section 2.5.4, occurs after the first anniversary of this Agreement but on or prior to the second anniversary of this Agreement, one hundred four percent (104%) of the sum of the principal amount to be redeemed plus any accrued but unpaid interest thereon;

(c)             if such voluntary redemption, including a redemption pursuant to sub-Section 2.5.4, occurs after the second anniversary of this Agreement but on or prior to the third anniversary of this Agreement, one hundred two percent (102%) of the sum of the principal amount to be redeemed plus any accrued but unpaid interest thereon; or

(d)             if such voluntary redemption, including a redemption pursuant to sub-Section 2.5.4, occurs after the third anniversary of this Agreement, one hundred percent (100%) of the sum of the principal amount to be redeemed plus any accrued but unpaid interest thereon;

2.5.3          Notice of Redemptions: Pro Rata Redemptions. Written notice of any redemption pursuant to sub-Section 2.5.1 or sub-Section 2.5.2 shall be given to all holders of the Notes at least thirty (30) Business Days prior to the date of any such redemption and if any such redemption relates to the Convertible Subordinated Notes such notice shall also state that the Noteholders have the right to convert the Convertible Subordinated Notes at any time prior to such redemption. Each redemption of the Notes pursuant to sub-Sections 2.5.1 and 2.5.2 shall be made so that the Notes then held by each holder shall be redeemed in a principal amount which shall bear the same ratio to the total unpaid principal amount being redeemed on all the Notes as the unpaid principal amount of the Notes then held by such holder bears to the aggregate unpaid principal amount of the Notes then outstanding.

2.5.4          Mandatory Repurchase of Notes. As soon as possible, and provided that the Borrower has such advance notice, no less than twenty (20) Business Days prior to the occurrence of a Mandatory Repurchase Event, Borrower shall furnish to each Noteholder written notice setting forth in reasonable detail the facts and circumstances underlying such Mandatory

12

Repurchase Event. The occurrence of any such Mandatory Repurchase Event shall constitute an irrevocable offer by Borrower to purchase all of the Notes held by such Noteholder at the prices specified in sub-Section 2.5.2 above with respect to voluntary redemptions, in any case, on the date of such Mandatory Repurchase Event (or, to the extent no advance notice was possible, the date which is 10 Business Days after the delivery of such notice), together with all accrued and unpaid interest on the amount so purchased through the date of purchase and together with any amounts otherwise payable pursuant to sub-Section 2.5.2. Following receipt of any notice constituting an offer to purchase the Notes hereunder, each Noteholder shall advise Borrower, by written notice, within ten (10) Business Days after receipt of such offer, as to whether it desires to sell all or any of the Notes, as applicable, held by it (in integral multiples of Five Hundred Thousand Dollars ($500,000)), specifying the principal amount of the Notes to be sold by it. If a Noteholder accepts such offer but does not specify an amount it wishes to receive, it will be deemed to have elected to sell all of the Notes held by it. If a Noteholder fails to respond to such offer by Borrower within the ten (10) Business Day acceptance period, such offer shall expire in accordance with its terms.

Section 2.6.           Default Rate of Interest. If an Event of Default has occurred and is continuing, from and after the date such Event of Default has occurred the entire outstanding unpaid principal balance of the Notes and any unpaid interest from time to time in default shall bear interest, payable on demand in cash, at the rate of fifteen percent (15%) per annum, compounded quarterly, or such lower rate as then may be the maximum rate permitted by Applicable Law; provided, however, that upon the cessation or cure of such Event of Default, if no other Event of Default is then continuing, the Notes shall again bear interest at the rate of twelve percent (12%) per annum as set forth in Section 2.1.

Section 2.7.           Maximum Legal Rate of Interest. Nothing in this Agreement or in the Notes shall require Borrower to pay interest at a rate in excess of the maximum rate permitted by Applicable Law.

Section 2.8.           Payment on Non-Business Days. Whenever any payment to be made shall be due on a day which is not a Business Day, such payment may be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest due.

Section 2.9.           Transfer and Exchange of Notes. The holder of any Note, as applicable, may, prior to maturity or prepayment thereof, surrender such Note at the principal office of Borrower for transfer or exchange, in accordance with applicable law. Any holder desiring to transfer or exchange any Note shall first notify Borrower in writing at least five (5) days in advance of such transfer or exchange. Within a reasonable time after such notice to Borrower from a holder of its intention to make such exchange and without expense (other than transfer taxes, if any) to such holder, Borrower shall issue in exchange therefor another Note in denominations of One Hundred Thousand Dollars ($100,000) and multiples thereof, except in the case of a Note for the balance of the aggregate amount of the Note, or Notes so transferred which shall be in a minimum denomination of One Hundred Thousand Dollars ($100,000), all as requested by the holder, for the same aggregate principal amount, as of the date of such issuance, as the unpaid principal amount of the Note or Notes so surrendered and having the same maturity and rate of interest, containing the same provisions and subject to the same terms and conditions

13

as the Note or Notes so surrendered (provided that no minimum shall apply to a liquidating distribution of Notes to investors in a Noteholder and any Notes so distributed may be subsequently transferred by such investor and its successors in the original denomination thereof without restriction under this sentence). Each new Note shall be made payable to such Person or Persons, or assigns, as the holder of such surrendered Note may designate, and such transfer or exchange shall be made in such a manner that no gain or loss of principal or interest shall result therefrom. Borrower shall have no obligation hereunder or under any Note to any person other than the registered holder of each such Note. Notwithstanding anything to the contrary contained herein, no Noteholder shall be permitted to transfer any of its Notes unless such Noteholder’s transferee has agreed in writing to be bound by the terms of this Agreement and the other Subordinated Notes Documents, including the representations and warranties set forth in Article IV hereof, by executing a joinder substantially in the form of Exhibit A attached hereto. Each transferee under this Section 2.9 shall deliver a Form W-8/W-9 in respect of itself and, if the transferee is a non-U.S. person that is a partnership for U.S. federal income tax purposes, a Form W-8/W-9 from each of its partners to the Borrower; provided, however, that if any transferee for any reason fails or is unable to deliver a Form W-8/W-9 in respect of itself or its partners, such transferee may nonetheless receive a transfer of Notes but shall be subject to withholding to the extent required by law.

Absent the continuance of a Default or an Event of Default at the time of any transfer hereunder, any out of pocket costs incurred by the Borrower in connection with such transfer, shall be for the account of the transferor.

Section 2.10.        Replacement of Notes. Upon surrender and cancellation of any mutilated Note, Borrower will issue a new Note of like tenor and amount and dated the date to which interest has been paid, in lieu of such mutilated Note. If any Note of which a Noteholder, or any of its partners is the holder is lost, stolen or destroyed, the affidavit of an authorized partner or officer of the holder setting forth (i) the circumstances with respect to such loss, theft or destruction and (ii) an indemnification by the holder of such lost, stolen or destroyed Note in favor of the Borrower with respect to such Note, shall be accepted as satisfactory evidence of such loss, theft or destruction, and Borrower will issue a new Note of like tenor and amount and dated the date to which interest has been paid, in lieu of such loss, stolen or destroyed Note.

Section 2.11.        Other Notices. So long as any Notes are outstanding, Borrower shall provide (if legally permitted to do so) written notice to each Noteholder at least thirty (30) Business Days prior to the occurrence or closing of a Mandatory Repurchase Event or a public offering of securities by Borrower setting forth in reasonable detail the facts and circumstances underlying such Mandatory Repurchase Event or public offering.

Section 2.12.        Performance of Obligations. Borrower agrees that its obligations hereunder shall not be discharged until payment and performance, in full, of the Obligations has occurred, and that its obligations under this Section 2.12 shall be absolute and unconditional, irrespective of, and unaffected by,

2.12.1 the genuineness, validity, regularity, enforceability or any future amendment of, or change in, this Agreement, any other Subordinated Notes Document or any other agreement, document or instrument to which Borrower is or may become a party;

14

2.12.2 the absence of any action to enforce this Agreement (including this Section 2.12) or any other Subordinated Notes Document or the waiver or consent with respect to any of the provisions thereof;

2.12.3 the existence, value or condition of, or any Noteholder’s failure to perfect its Lien against, any security for the Obligations or any action, or the absence of any action, by any Noteholder in respect thereof (including the release of any such security); or

2.12.4 the insolvency of any Noteholder.

Section 2.13.        Issue Price; Original Issue Discount. Borrower and each Noteholder recognize and agree that (i) the Convertible Subordinated Notes will not be issued with original issue discount within the meaning of Section 1273 of the Code, and (ii) the issue price of any Note issued by the Company, within the meaning of Section 1273 of the Code, will be determined in accordance with the rules in Section 1273(b)(3) or 1273(b)(4), as applicable, at the time of the conversion of the Convertible Subordinated Note in respect of which such Note is issued. Borrower and each Noteholder agree to comply with all tax, accounting, regulatory and other reporting requirements in a manner which is consistent with the foregoing.

Section 2.14.        Ranking. The Obligations and the rights and remedies of the Noteholders under the Subordinated Notes Documents shall be senior in right of payment to all Subordinated Debt of Borrower and its Subsidiaries.

Section 2.15.        Withholding and Tax Form Delivery . Each Noteholder (including any transferee hereunder) shall deliver to the Borrower a duly completed Form W-8/W-9 in respect of itself (and periodic updates thereof following expiration of the validity of any previously delivered Form W-8/W-9) and, if the Noteholder is a non-U.S. person that is a partnership for U.S. federal income tax purposes, a duly completed Form W-8/W-9 from each of its partners (and periodic updates thereof following expiration of the validity of any previously delivered Form W-8/W-9); provided, however, that if any Noteholder for any reason fails or is unable to deliver such a form in respect of itself or its partners, payments to such Noteholder shall be subject to withholding to the extent required by law; provided, further, the Borrower shall not be responsible for grossing up any payments to a Noteholder made in connection with the Subordinated Debt Documents which are subject to withholding.
