due January 31, 2013

This is the Senior Subordinated Note due January 31, 2013 (the “Note”) provided for in the Senior Subordinated Note and Warrant Purchase Agreement dated as of the date hereof (as amended, restated, supplemented or otherwise modified from time to time, the “Purchase Agreement”) by and between the Payee, as purchaser, and the Makers, as sellers.

This Note is one of the Related Documents referred to in the Purchase Agreement.

FOR VALUE RECEIVED, the Makers hereby promises to pay to the order of the Payee the Principal Amount of ONE MILLION TWO HUNDRED THOUSAND DOLLARS ($1,200,000), together with Interest, Prepayment Premium and Assessments (each as defined herein or in the Purchase Agreement), upon the terms and subject to the conditions set forth in this Note.

Section 1. Definitions and Miscellaneous Provisions

Any capitalized term used but not otherwise defined in this Note shall have the definition given such term as set forth in the Purchase Agreement, which definition is, to the extent applicable, incorporated herein by reference. The provisions of Section 12 of the Purchase Agreement are applicable to this Note and are incorporated herein by reference.

Section 2. Maturity and Pay Off

The unpaid Principal Amount of this Note, together with all accrued but unpaid Interest and Assessments, shall be due and payable in full on the Maturity Date. Payment of the Principal Amount and all accrued but unpaid Interest and Assessments may be Accelerated upon the occurrence of an Event of Default as provided for in this Note. Upon request of the Makers, the Payee will furnish to the Makers a letter setting forth the amount of Principal Amount, Interest, Prepayment Premium and Assessments required to pay this Note in full as of a specified Pay Off Date.

Section 3. Interest

Interest shall accrue on the unpaid Principal Amount from the date of this Note through and including the Pay Off Date at the applicable interest rate (“Interest”). All accrued but unpaid Interest shall be paid monthly in arrears on each Payment Date specified above, commencing February 29, 2008.

At all times that the Default Interest Rate is not in effect, the interest rate on this Note shall be a fixed rate per annum equal to the Stated Interest Rate. Upon the occurrence of an Event of Default, this Note shall accrue interest at a rate per annum equal to the Default Interest Rate unless the Payee elects, in the sole exercise of its discretion, to waive imposition of the Default Interest Rate by giving written notice of such election to the Makers (a “Default Rate Waiver”). Absent a Default Rate Waiver, the interest rate on this Note shall be a fixed rate per annum equal to the Default Interest Rate, and the Default Interest Rate shall continue to be the interest rate on this Note until the Event of Default has been remedied or waived and no other Default or Event of Default is continuing, unremedied or unwaived, provided that the Note has not been Accelerated.

Notwithstanding any provision of this Note to the contrary: (i) in no event shall the interest rate on this Note be a rate per annum in excess of the maximum interest rate permissible under Applicable Law (including any applicable interest rate ceiling imposed by United States Small Business Administration regulations as applicable), and (ii) to the extent that Interest (or other amounts paid with respect to this Note that are deemed to be Interest under Applicable

2

Law) results in Interest payments in excess of those permitted under Applicable Law, such excess payments shall be applied first to the payment of the unpaid Principal Amount, second to the payment of any other amounts due from the Makers to the Payee, and third, if no other obligations are owing to the Payee, then refunded to the Makers. The Makers agree that if such excess payments are applied in the manner provided for in this paragraph, then to the fullest extent permitted by Applicable Law, Payee shall not be subject to any penalty provided for by any Applicable Law relating to charging or collecting Interest in excess of that permitted by Applicable Law.

Interest shall accrue based upon: (i) the actual number of days elapsed over each month, including any additional days elapsed because the scheduled Payment Date fell on a day other than a Business Day; (ii) months consisting of thirty (30) days each; (iii) quarters consisting of three (3) 30-day months, and (iv) monthly compounding of any Interest or Assessment accrued but unpaid as of each Payment Date.

Section 4. Principal Amount

The Principal Amount shall be paid in full on the Maturity Date.

Section 5. Prepayments

The Makers may prepay the Principal Amount in whole at any time or in part from time to time; provided that (i) the Makers deliver irrevocable written notice to the Payee at least thirty (30) days prior to such prepayment, which notice shall include written confirmation from the Makers that such prepayment is permissible under the Senior Loan Agreement, (ii) each partial prepayment of Principal Amount shall be equal to $250,000 or an integral multiple thereof, and (iii) any such prepayment shall be made together with payment of a Prepayment Premium as provided below if such prepayment is made on or prior to the second anniversary of the Date of Note.

If the Principal Amount is paid on or prior to the second anniversary of the Date of Note, the Makers shall pay all accrued but unpaid Interest plus an amount equal to the sum of the Interest that would have accrued and been due and payable under this Note from the date of such prepayment through the second anniversary of the Date of Note (a “Prepayment Premium”).

If notice of prepayment is given, the Principal Amount to be prepaid as stated in the notice, together with Interest accrued thereon through the date of prepayment with respect to the Principal Amount prepaid, all unpaid Assessments and a Prepayment Premium, if any, shall become due and payable on the date specified in the notice. In the case of the redemption of less than all of the outstanding Principal Amount hereof, the amounts so paid shall be applied in the following order: (a) first, to payment of the Prepayment Premium, if any; (b) second, to payment of accrued Interest; (c) third, to payment of unpaid Assessments; and (d) finally, to payment of the Principal Amount, in inverse order of the principal installments hereof.

Section 6. Late Payments

A payment of Principal Amount, Interest, Prepayment Premium, or Assessment shall be deemed to be a Payment Default if such payment is not received prior to 2:00 p.m., Hudson, Ohio time on the fifth day after such payment is due. The Payee may, in the sole exercise of its discretion, by written notice to the Makers, assess a fee of $500 for each Payment Date with respect to which there is a late payment to reimburse the Payee for the cost of processing such late payment. Such late fee shall be deemed to be an Assessment for purposes of this Note. The Payee may not assess a late fee with respect to any Payment Date after payment of this Note is Accelerated.
