corporation (“Borrower”), and The HillStreet Fund, L.P., a Delaware limited partnership, its permitted successors and assigns (“Lender”). 
 RECITALS 
 WHEREAS, the parties entered into that certain Subordinated Loan and Security Agreement as of
July 28, 2000 (the “Loan Agreement”), whereby Lender made a term loan to Borrower in the amount of $3,000,000. 
 WHEREAS, the
Loan Agreement provides for the repayment of principal pursuant to an amortization schedule beginning on August 31, 2005.

Borrower (the “Warrant”). 
 WHEREAS, the Warrant Agreement provides that Lender shall have the right to “put” the
Warrant (or shares of Borrower common stock acquired by the exercise of the Warrant) to Borrower at any time on or after the earlier to occur of July 28, 2005 or the commencement of any Capital Transaction (as defined in the Warrant Agreement)
(the “Put Exercise Date”). 
 WHEREAS, (i) Borrower is currently working to consummating a business combination transaction
with DPAC Technologies Corp. (“DPAC”) whereby Borrower would become a wholly-owned subsidiary of DPAC (the “DPAC Transaction”) and (ii) Development Capital Ventures, LP (“DCV”), an affiliate of Borrower, has agreed
to provide DPAC a secured short term bridge loan and DCV and DPAC have agreed to enter into a License Agreement whereby DPAC will grant to DCV an exclusive, worldwide and perpetual right and license to manufacture, develop, market and sell all of

 WHEREAS, the parties desire to hereby amend the Loan
Agreement and the Warrant Agreement to reflect the foregoing. 

 NOW THEREFORE, in consideration of the mutual covenants and agreements set forth herein, and for other
good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound hereby, agree as follows: 
 1. Repayment of Loan Principal. 
 1.1. The definition of Principal Payment Dates contained in Section 1.1 of the Loan Agreement is amended and restated in its entirety to read as follows: 
 “ ‘Principal Payment Dates’ shall have the meaning so ascribed in Section 2.2(e).”

 “(d) Principal Payments. Prior to November 30, 2005, provided that Lender has not accelerated the Loan pursuant to Section 9.9
hereof, Borrower shall not be obligated to make any payment of principal on the Loan. Beginning November 30, 2005, quarterly installments of principal on the Subordinated Note shall be payable on each Principal Payment Date as set forth in
subsection (e) below, and on the date the Loan is due (whether by maturity, acceleration or otherwise), in an amount equal to pay in full the entire unpaid principal and accrued interest.” 
 1.3. A new Section 2.2(e) is added following Section 2.2(d) as follows: 
 “(e) Amortization. Pursuant to subsection (d) above, payments shall be made on each of the following dates (each a “Principal

 1.4. Notwithstanding anything to the contrary in the Loan Agreement, all Obligations under the
Loan Agreement, as hereby amended, shall become immediately due and payable in full upon the earlier to occur of (i) the consummation of the DPAC Transaction or (ii) the acquisition by Borrower of the DPAC Technology in fee simple. By way
of clarification, the acceleration provided for in the preceding sentence shall not be triggered by Borrower simply becoming a licensee directly or indirectly under the License Agreement.

 2. Amendment Fee. On the date of this Amendment, Borrower shall pay to Lender a fee in the amount of Fifty
Thousand Dollars ($50,000.00); such fee shall be paid in cash or via wire transfer of immediately available funds to an account designated by Lender. 
 3.
Extension of Lender’s Put Right. The definition of Put Exercise Date contained in Section 1 of the Warrant Agreement is amended and restated in its entirety to read as follows:

 4.3. Entire Agreement. This Amendment, together with the Loan Agreement, Warrant Agreement and that certain Warrant Purchase Agreement by and
among Lender, Borrower and DCV dated May 31, 2005, as amended from time to time, constitutes the complete, final and exclusive understanding and agreement of the parties and supersedes any and all prior or contemporaneous negotiations,
correspondence, understandings and agreements, whether oral or written, between the parties with respect to the subject matter hereof. 
 4.4. Use of Defined Terms. Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Loan Agreement or the Warrant Agreement, as the case may be.

foregoing. 
 NOW THEREFORE, in consideration of the mutual covenants and agreements set forth herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound hereby, agree as follows: 
 1. Repayment of Loan Principal; Amendment Fee. 
 1.1 Section 2.2(d) of the Loan Agreement is
amended and restated in its entirety to read as follows: 
 “(d) Principal Payments. Provided that Lender has not accelerated the
Loan pursuant to Section 9.9 hereof, Borrower is obligated to make repayments of principal on the Loan in accordance with Section 2.2(e) of this Agreement. Quarterly installments of principal on the Loan shall be payable on each Principal
Payment Date as set forth in subsection (e) below, and on the date the Loan is due (whether by maturity, acceleration or otherwise), in an amount equal to pay in full the entire unpaid principal and accrued interest.” 
 1.2 Section 2.2(e) of the Loan Agreement is amended and restated in its entirety to read as follows: 
 “(e) Amortization. 
  

	 	(i)	Pursuant to subsection (d) above, Borrower shall pay an “Amendment Fee” in the amount set forth below per month for up to four (4) consecutive months, the first
payment of which shall be made on the date hereof. The Amendment Fee shall be due on the last business day of each month thereafter, until the earlier of: (A) the month in which the Borrower ceases to pay the Amendment Fee to Lender, at which

 2

1.3 Notwithstanding anything to the contrary in the Loan Agreement, all Obligations under the Loan Agreement, as hereby amended, shall become
immediately due and payable in full upon the earlier to occur of (i) the consummation of the DPAC Transaction or (ii) the acquisition by Borrower of the DPAC Technology in fee simple. By way of clarification, the acceleration provided for
in the preceding sentence shall not be triggered by Borrower simply becoming a licensee directly or indirectly under the License Agreement. 
 1.4 The Amendment Fee shall be paid in cash or via wire transfer of immediately available funds to an account designated by Lender. 
  

	2.	Extension of Lender’s Put Right. 

 The
definition of Put Exercise Date contained in Section 1 of the Warrant Agreement is amended and restated in its entirety to read as follows: 
 “ ‘Put Exercise Date’ shall mean the earlier to occur of (a) the first Principal Payment Date, as defined in that certain Subordinated Loan and Security Agreement as of July 28, 2000, by and between the
Company and The HillStreet Fund, L.P., as amended, or (b) the consummation of any Capital Transaction.” 
  

	3.	State of Ohio Loan. 

 3.1 The Lender agrees to enter
into an Intercreditor Agreement, substantially in the form attached hereto as Exhibit A (the “Intercreditor Agreement”), for the purpose of subordinating the priority of the any lien under this Agreement so that any lien arising from
indebtedness owed by the Borrower to the State of Ohio pursuant to that certain Loan Agreement by and between the Borrower and the Director of Development of the State of Ohio, dated as of January 27, 2006 will be pari passu with any lien
arising under this Loan. The Intercreditor Agreement will not affect the subordination of Lender’s indebtedness to the indebtedness owed by the Borrower to National City Bank. 
 3.2 Lender shall have the right to approve the terms and conditions of an escrow agreement into which the proceeds from the State of Ohio loan shall be
deposited pending the completion of the DPAC Transaction or the acquisition by Borrower of the DPAC Technology in fee simple. Lender shall further have the right to approve the terms and conditions of any use of such proceeds if, prior to such use,
all Obligations to the Lender Loan are not paid in full. Borrower acknowledges that the Lender’s willingness to enter into this Second Amendment is predicated upon the anticipated payment in full of all Obligations due to Lender as a result of
either the completion of the DPAC Transaction or the acquisition by Borrower of the DPAC Technology in fee simple. Accordingly, Lender shall have the right to withhold any approval requested under this Section, in its sole and absolute discretion.

correspondence, understandings and agreements, whether oral or written, between the parties with respect to the subject matter hereof.
