Exhibit 10.5

		Master Revolving Note
		Variable Rate-Maturity Date-Optional Advances (Business and Commercial Loans Only)

On the Maturity Date, as stated above, for value received, the undersigned promise(s) to pay to the order of Comerica Bank (“Bank”), at any office of the Bank in the State of Michigan, Four Million Five Hundred Thousand Dollars (U.S.) (or that portion of it advanced by the Bank and not repaid as later provided) with interest until maturity, whether by acceleration or otherwise, or until Default, as later defined, at a per annum rate equal to the Bank’s prime rate from time to time in effect plus one-quarter of one percent (1/4%) per annum, and after that at a rate equal to the rate of interest otherwise prevailing under this Note plus three percent (3%) per annum (but in no event in excess of the maximum rate permitted by law). The Bank’s “prime rate” is that annual rate of interest so designated by the Bank and which is changed by the Bank from time to time. Interest rate changes will be effective for interest computation purposes as and when the Bank’s prime rate changes. Interest shall be calculated on the basis of a 360-day year for actual number of days the principal is outstanding. Accrued interest on this Note shall be payable on the first day of each month commencing July 1, 2008, until the Maturity Date (set forth above) when all amounts outstanding under this Note shall be due and payable in full. If any payment of principal or interest under this Note shall be payable on a day other than a day on which the Bank is open for business, this payment shall be extended to the next succeeding business day and interest shall be payable at the rate specified in this Note during this extension. A late payment charge equal to five percent (5%) of each late payment may be charged on any payment not received by the Bank within ten (10) calendar days after the payment due date, but acceptance of payment of this charge shall not waive any Default under this Note.

The principal amount payable under this Note shall be the sum of all advances made by the Bank to or at the request of the undersigned, less principal payments actually received in cash by the Bank. The books and records of the Bank shall be the best evidence of the principal amount and the unpaid interest amount owing at any time under this Note and shall be conclusive absent manifest error. No interest shall accrue under this Note until the date of the first advance made by the Bank; after that interest on all advances shall accrue and be computed on the principal balance outstanding from time to time under this Note until the same is paid in full. At no time shall the Bank be under any obligation to make any advances to the undersigned pursuant to this Note (notwithstanding anything expressed or implied in this Note or elsewhere to the contrary, including without limit if the Bank supplies the undersigned with a borrowing formula) and the Bank, at any time and from time to time, without notice, and in its sole discretion, may refuse to make advances to the undersigned without incurring any liability due to this refusal and without affecting the undersigned’s liability under this Note for any and all amounts advanced.

This Note and any other indebtedness and liabilities of any kind of the undersigned (or any of them) to the Bank, and any and all modifications, renewals or extensions of it, whether joint or several, contingent or absolute, now existing or later arising, and however evidenced (collectively “Indebtedness”), are secured by and the Bank is granted a security interest in all items deposited in any account of any of the undersigned with the Bank and by all proceeds of these items (cash or otherwise), all account balances of any of the undersigned from time to time with the Bank, by all property of any of the undersigned from time to time in the possession of the Bank and by any other collateral, rights and properties described in each and every deed of trust, mortgage, security agreement, pledge, assignment and other security or collateral agreement which has been, or will at any time(s) later be, executed by any (or all) of the undersigned to or for the benefit of the Bank (collectively “Collateral”). Notwithstanding the above, (i) to the extent that any portion of the indebtedness is a consumer loan, that portion shall not be secured by any deed of trust, mortgage on or other security interest in any of the undersigned’s principal dwelling or in any of the undersigned’s real property which is not a purchase money security interest as to that portion, unless expressly provided to the contrary in another place, or (ii) if the undersigned (or any of them) has (have) given or give(s) Bank a deed of trust or mortgage covering California real property, that deed of trust or mortgage shall not secure this Note or any other indebtedness of the undersigned (or any of them), unless expressly provided to the contrary in another place.

If the undersigned (or any of them) or any guarantor under a guaranty of all or part of the indebtedness (“guarantor”) (a) fail(s) to pay any of the indebtedness when due, by maturity, acceleration or otherwise, or fail(s) to pay any indebtedness owing on a demand basis upon demand; or (b) fail(s) to comply with any of the terms or provisions of any agreement between the undersigned (or any of them) or any such guarantor and the Bank; or (c) become(s) insolvent or the subject of a voluntary or involuntary proceeding in bankruptcy, or a reorganization, arrangement or creditor composition

proceeding, (if a business entity) cease(s) doing business as a going concern, (if a natural person) die(s) or become(s) incompetent, (if a partnership) dissolve(s) or any general partner of it dies, becomes incompetent or becomes the subject of a bankruptcy proceeding or (if a corporation or a limited liability company) is the subject of a dissolution, merger or consolidation; or (d) if any warranty or representation made by any of the undersigned or any guarantor in connection with this Note or any of the Indebtedness shall be discovered to be untrue or incomplete; or (e) if there is any termination, notice of termination, or breach of any guaranty, pledge, collateral assignment or subordination agreement relating to all or any part of the Indebtedness; or (f) if there is any failure by any of the undersigned or any guarantor to pay when due any of its indebtedness (other than to the Bank) or in the observance or performance of any term, covenant or condition in any document evidencing, securing or relating to such indebtedness; or (g) if the Bank deems itself insecure believing that the prospect of payment of this Note or any of the Indebtedness is impaired or shall fear deterioration, removal or waste of any of the Collateral; or (h) if there is filed or issued a levy or writ of attachment or garnishment or other like judicial process upon the undersigned (or any of them) or any guarantor or any of the Collateral, including without limit, any accounts of the undersigned (or any of them) or any guarantor with the Bank, then the Bank, upon the occurrence of any of these events (each a “Default”), may at its option and without prior notice to the undersigned (or any of them), declare any or all of the Indebtedness to be immediately due and payable (notwithstanding any provisions contained in the evidence of it to the contrary), sell or liquidate all or any portion of the Collateral, set off against the Indebtedness any amounts owing by the Bank to the undersigned (or any of them), charge interest at the default rate provided in the document evidencing the relevant Indebtedness and exercise any one or more of the rights and remedies granted to the Bank by any agreement with the undersigned (or any of them) or given to it under applicable law. All payments under this Note shall be in immediately available United States funds, without setoff or counterclaim.
