Exhibit 10.15

		Installment Note
		Prime Referenced Rate

FOR VALUE RECEIVED, the undersigned promise(s) to pay to the order of COMERICA BANK (herein called “Bank”), at any office of the Bank in the State of Michigan, the principal sum of One Million Eight Hundred Fifty Thousand Dollars ($1,850,000), payable in monthly installments equal to $38,542.00 each, plus interest, commencing on August 1, 2011, and on each succeeding Installment Payment Date thereafter, until the Maturity Date set forth above, when the entire unpaid balance of principal, interest and all other sums hereunder shall be due and payable in full (unless sooner accelerated in accordance with the terms of this Note).

Subject to the terms and conditions of this Note, the unpaid principal balance outstanding under this Note from time to time shall bear interest at the Prime Referenced Rate plus the Applicable Margin.

Interest accruing hereunder shall be computed on the basis of a 360 day year and shall be assessed for the actual number of days elapsed, and in such computation, effect shall be given to any change in the applicable interest rate as a result of any change in the Prime Referenced Rate on the date of each such change.

Accrued and unpaid interest hereunder shall be payable, in arrears, on each Installment Payment Date, including, without limitation, the Maturity Date (unless sooner accelerated in accordance with the terms of this Note).

Payments under this Note shall be first applied to accrued and unpaid interest hereunder and the balance, if any, to principal.

In the event the periodic installments set forth above are inclusive of interest, the undersigned hereby acknowledge(s) and agree(s) that such installments are based upon the original principal amount of Indebtedness outstanding under this Note, an assumed fixed rate of interest, and an assumed amortization term, notwithstanding the fact that the applicable interest rate may change from time to time during the term of this Note. Therefore, in the event that the applicable interest rate changes at any time as a result of any change(s) in the Prime Referenced Rate, Bank may, in its sole discretion, recalculate the installments of principal and interest required to be made by the undersigned under and pursuant to the terms of this Note, and the undersigned agree(s) to pay such installments as they may be recalculated by Bank, and the undersigned acknowledge(s) and agree(s) that any such recalculation shall not affect the Maturity Date of this Note or any other terms or provisions herein set forth.

From and after the occurrence of any Default hereunder, and so long as any such Default remains unremedied or uncured thereafter, the Indebtedness outstanding under this Note shall bear interest at a per annum rate of three percent (3%) above the otherwise applicable interest rate hereunder, which interest shall be payable upon demand. In addition to the foregoing, a late payment charge equal to five percent (5%) of each late payment hereunder may be charged on any payment not received by Bank within ten (10) calendar days after the payment due date therefor, but acceptance of payment of any such charge shall not constitute a waiver of any Default hereunder.

In no event shall the interest payable under this Note at any time exceed the maximum rate permitted by law.

The amount from time to time outstanding under this Note, the applicable interest rate and the amount and date of any repayment shall be noted on Bank’s records, which records shall be conclusive evidence thereof, absent manifest error; provided, however, any failure by Bank to make any such notation, or any error in any such notation, shall not relieve the undersigned of its/their obligations to repay Bank all amounts payable by the undersigned to Bank under or pursuant to this Note, when due in accordance with the terms hereof.

In the event that any payment under this Note becomes due and payable on any day which is not a Business Day, the due date thereof shall be extended to the next succeeding Business Day, and, to the extent applicable, interest shall continue to accrue and be payable thereon during such extension at the rate(s) set forth in this Note.

All payments to be made by the undersigned to Bank under or pursuant to this Note shall be in immediately available United States funds, without setoff or counterclaim, and in the event that any payments submitted hereunder are in funds not available until collected, said payments shall continue to bear interest until collected.

Any Indebtedness outstanding hereunder may be prepaid without penalty or premium. Any prepayment hereunder shall also be accompanied by the payment of all accrued and unpaid interest on the amount so prepaid. Partial prepayments hereunder shall be applied to the installments hereunder in the inverse order of their maturities.

If the adoption after the date hereof, or any change after the date hereof in, any applicable law, rule or regulation (whether domestic or foreign) of any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by Bank with any request or directive (whether or not having the force of law) made by any such authority, central bank or comparable agency after the date hereof: (a) shall subject Bank to any tax, duty or other charge with respect to this Note or any Indebtedness hereunder, or shall change the basis of taxation of payments to Bank of the principal of or interest under this Note or any other amounts due under this Note in respect thereof (except for changes in the rate of tax on the overall net income of Bank imposed by the jurisdiction in which Bank’s principal executive office is located); or (b) shall impose, modify or deem applicable any reserve (including, without limitation, any imposed by the Board of Governors of the Federal Reserve System), special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by Bank, or shall impose on Bank or the foreign exchange and interbank markets any other condition affecting this Note or the Indebtedness hereunder; and the result of any of the foregoing is to increase the cost to Bank of maintaining any part of the Indebtedness hereunder or to reduce the amount of any sum received or receivable by Bank under this Note by an amount deemed by the Bank to be material, then the undersigned shall pay to Bank, within fifteen (15) days of the undersigned’s receipt of written notice from Bank demanding such compensation, such additional amount or amounts as will compensate Bank for such increased cost or reduction. A certificate of Bank, prepared in good faith and in reasonable detail by Bank and submitted by Bank to the undersigned, setting forth the basis for determining such additional amount or amounts necessary to compensate Bank shall be conclusive and binding for all purposes, absent manifest error.

In the event that any applicable law, treaty, rule or regulation (whether domestic or foreign) now or hereafter in effect and whether or not presently applicable to Bank, or any interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof, or compliance by Bank with any guideline, request or directive of any such authority (whether or not having the force of law), including any risk-based capital guidelines, affects or would affect the amount of capital required or expected to be maintained by Bank (or any corporation controlling Bank), and Bank determines that the amount of such capital is increased by or based upon the existence of any obligations of Bank hereunder or the maintaining of any Indebtedness hereunder, and such increase has the effect of reducing the rate of return on Bank’s (or such controlling corporation’s) capital as a consequence of such obligations or the maintaining of such Indebtedness hereunder to a level below that which Bank (or such controlling corporation) could have achieved but for such circumstances (taking into consideration its policies with respect to capital adequacy), then the undersigned shall pay to Bank, within fifteen (15) days of the undersigned’s receipt of written notice from Bank demanding such compensation, additional amounts as are sufficient to compensate Bank (or such controlling corporation) for any increase in the amount of capital and reduced rate of return which Bank reasonably determines to be allocable to the existence of any obligations of the Bank hereunder or to maintaining any Indebtedness hereunder. A certificate of Bank as to the amount of such compensation, prepared in good faith and in reasonable detail by the Bank and submitted by Bank to the undersigned, shall be conclusive and binding for all purposes absent manifest error.

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 and whether incurred voluntarily or involuntarily, known or unknown, or originally payable to the Bank or to a third party and subsequently acquired by Bank including, without limitation, any late charges; loan fees or charges; overdraft indebtedness; costs incurred by Bank in establishing, determining, continuing or defending the validity or priority of any security interest, pledge or other lien or in pursuing any of its rights or remedies under any loan document (or otherwise) or in connection with any proceeding involving the Bank as a result of any financial accommodation to the undersigned (or any of them); and reasonable costs and expenses of attorneys and paralegals, whether inside or outside counsel is used, and whether any suit or other action is instituted, and to court costs if suit or action is instituted, and whether any such fees, costs or expenses are incurred at the trial court level or on appeal, in bankruptcy, in administrative proceedings, in probate proceedings or otherwise (collectively “Indebtedness”) are secured by and the Bank is granted a security interest in and lien upon 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 or 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, or (iii) if the undersigned (or any of them) has (have) given or give(s) the Bank a deed of trust or mortgage covering real property which, under Texas law, constitutes the homestead of such person, 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.

Upon the occurrence and at any time during the continuance or existence of any Default, the Bank 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.

The undersigned authorize(s) the Bank to charge any account(s) of the undersigned (or any of them) with the Bank for any and all sums due hereunder when due; provided, however, that such authorization shall not affect any of the undersigned’s obligation to pay to the Bank all amounts when due, whether or not any such account balances that are maintained by the undersigned with the Bank are insufficient to pay to the Bank any amounts when due, and to the extent that are insufficient to pay to the Bank all such amounts, the undersigned shall remain liable for any deficiencies until paid in full.
