This Note is a note under which Advances, repayments and re-Advances may be made from time to lime, subject to the terms and conditions of this Note.

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 LIMITATION, IF BANK SUPPLIES THE UNDERSIGNED WITH A BORROWING FORMULA) IN THE EVENT THAT ANY OEFAULT, OR ANY CONDITION OR EVENT WHICH, WITH THE GIVING OF NOTICE OR THE RUNNING OF TIME, OR BOTH, WOULD CONSTITUTE A DEFAULT, SHALL HAVE OCCURRED ANO BE CONTINUING OR EXIST, IN WHICH EVENT, 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 ANO WITHOUT AFFECTING THE UNDERSIGNED'S LIABILITY UNDER THIS NOTE FOR ANY AND ALL AMOUNTS ADVANCED.

Subject to the terms and conditions of this Note, each of the Advances made hereunder shall bear interest at the Prime Referenced Rate plus the Applicable Margin.

Accrued and unpaid interest on the unpaid principal balance of each outstanding Advance hereunder shall be payable monthly, in arrears, on the first Business Day of each month, from the date made until the same is paid in full (whether in accordance with the terms hereof, by acceleration, or otherwise). Interest accruing hereunder shall be computed on the basis of a year of 360 days, and shall be assessed for the actual number of days elapsed, and in such computation, effect shall be given to any change in the interest rate as a result of any change in the Prime Referenced Rate on the date of each such change.

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, 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. The term 'Maximum Rate', as used herein, shall mean at the particular time in question the maximum nonusurious rate of interest which, under applicable law, may then be charged on this Note. If on any day the applicable interest rate hereunder in respect of any Indebtedness under this Note shall exceed the Maximum Rate for that day, the rate of interest applicable to such Indebtedness shall be fixed at the Maximum Rate on that day and on each day thereafter until the total amount of interest accrued on the unpaid principal balance of this Note equals the total amount of interest which would have accrued if there had been no Maximum Rate. If such maximum rate of interest changes after the date hereof, the Maximum Rate shall be automatically increased or decreased, as the case may be, without notice to the undersigned from time to time as of the effective date of each change in such maximum rate. For purposes of determining the Maximum Rate under the law of the State of Texas, the applicable interest rate ceiling shall be the 'weekly ceiling' from time to time in effect under Chapter 303 of the Texas Finance Code, as amended.

The amount and date of each Advance, 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.

The undersigned may request an Advance hereunder either (i) upon the delivery to Bank of a written Request for Advance duly completed and executed by the undersigned (as herein provided) or, (ii) to the extent applicable, pursuant to a request submitted through Bank's Loan Management System (each a "Request”), in each case, subject to the following: (a) no Default, or any condition or event which, with the giving of notice or the running of time, or both, would constitute a Default, shall have occurred and be continuing or exist under this Note; (b) each such Request shall be delivered to Bank by 11:00 a.m. (Detroit, Michigan time) on the proposed date of the requested Advance; (c) after giving effect to such Advance, the aggregate principal amount of Advances made under this Note (excluding refundings and conversions of outstanding Advances) shall not exceed the Loan Amount; and (d) a Request, once delivered or submitted to Bank, shall not be revocable by the undersigned.

In the event that the undersigned is unable to request Advances hereunder through the Bank's Loan Management System, Advances hereunder may be requested by delivery or submission to Bank by hand delivery, first class mail, overnight courier, facsimile, email or other means of delivery acceptable to Bank, of a written Request for Advance duly completed and executed by the undersigned. Advances hereunder may be requested in the undersigned's discretion by telephonic notice to Bank. Any Advance requested by telephonic notice shall be confirmed by the undersigned that same day by submission to Bank of a written Request for Advance, as provided herein. The undersigned acknowledge(s) that if Bank makes an Advance based on a request made by telephone, facsimile, email or other means of delivery (other than by hand delivery, first class mail or overnight courier), it shall be for the undersigned's convenience and all risks Involved in the use of any such procedure shall be borne by the undersigned, and the undersigned expressly agree(s) to indemnify and hold Bank harmless therefor. Bank shall have no duty to confirm the authority of anyone requesting an Advance by telephone, facsimile, email or any such other means of delivery. In the event that the undersigned elect(s) to request Advances by telephonic notice, facsimile, email or other means of delivery acceptable to Bank, the undersigned acknowledge(s) and agree(s) that Bank may Impose or require such verification, authentication and other procedures as Bank may require from time to time.

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 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.

The undersigned may prepay all or part of the outstanding balance of any Indebtedness hereunder at any time without premium or penalty. Any prepayment hereunder shall also be accompanied by the payment of all accrued and unpaid interest on the amount so prepaid.

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 Change in Law affects or would affect the amount of capital or liquidity required or expected to be maintained by Bank (or any corporation controlling Bank), and Bank determines that the amount of such capital or liquidity 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 and liquidity), 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/or liquidity 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.

As used in this Note, the word 'undersigned" means, individually and collectively, each maker, accommodation party, endorser and other party signing this Note in a similar capacity. If any provision of this Note is unenforceable in whole or part for any reason, the remaining provisions shall continue to be effective. THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS, WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES. Chapter 346 of the Texas Finance Code (and as the same may be incorporated by reference in other Texas statutes) shall not apply to the Indebtedness evidenced by this Note.

This Note and all other documents, instruments and agreements evidencing, governing, securing, guaranteeing or otherwise relating to or executed pursuant to or in connection with this Note or the Indebtedness evidenced hereby (whether executed and delivered prior to, concurrently with or subsequent to this Note), as such documents may have been or may hereafter be amended from time to time (the "Loan Documents") are intended to be performed in accordance with, and only to the extent permitted by, all applicable usury laws. If any provision hereof or of any of the other Loan Documents or the application thereof to any person or circumstance shall, for any reason and to any extent, be invalid or unenforceable, neither the application of such provision to any other person or circumstance nor the remainder of the instrument in which such provision is contained shall be affected thereby and shall be enforced to the greatest extent permitted by law. It is expressly stipulated and agreed to be the intent of the holder hereof to at all times comply with the usury and other applicable laws now or hereafter governing the interest payable on the indebtedness evidenced by this Note. If the applicable law is ever revised, repealed or judicially interpreted so as to render usurious any amount called for under this Note or under any of the other Loan Documents, or contracted for, charged, taken, reserved or received with respect to the indebtedness evidenced by this Note, or if Bank's exercise of the option to accelerate the maturity of this Note, or if any prepayment by the undersigned or prepayment agreement results (or would, if complied with, result) in the undersigned having paid, contracted for or being charged for any interest in excess of that permitted by law, then it is the express intent of the undersigned and Bank that this Note and the other Loan Documents shall be limited to the extent necessary to prevent such result and all excess amounts theretofore collected by Bank shall be credited on the principal balance of this Note or, if fully paid, upon such other Indebtedness as shall then remain outstanding (or, if this Note and all other Indebtedness have been paid in full, refunded to the undersigned), and the provisions of this Note and the other Loan Documents shall immediately be deemed reformed and the amounts thereafter collectable hereunder and thereunder reduced, without the necessity of the execution of any new document, so as to comply with the then applicable law, but so as to permit the recovery of the fullest amount otherwise called for hereunder or thereunder. All sums paid, or agreed to be paid, by the undersigned for the use, forbearance, detention, taking, charging, receiving or reserving of the indebtedness of the undersigned to Bank under this Note or arising under or pursuant to the other Loan Documents  shall, to the maximum extent permitted by applicable Jaw, be amortized, prorated, allocated and spread throughout the full term of such indebtedness until payment in full so that the rate or amount of interest on account of such indebtedness does not exceed the usury ceiling from time to time in effect and applicable to such Indebtedness for so long as such indebtedness is outstanding. To the extent federal law permits Bank to contract for, charge or receive a greater amount of interest, Bank will rely on federal law instead of the Texas Finance Code, as supplemented by Texas Credit Title, for the purpose of determining the Maximum Rate. Additionally, to the maximum extent permitted by applicable law now or hereafter in effect, Bank may, at its option and from time to time, implement any other method of computing the Maximum Rate under the Texas Finance Code, as supplemented by Texas Credit Title, or under other applicable law, by giving notice, if required, to the undersigned as provided by applicable law now or hereafter in effect. Notwithstanding anything to the contrary contained herein or in any of the other Loan Documents, it is not the intention of Bank to accelerate the maturity of any interest that has not accrued at the time of such acceleration or to collect unearned interest at the time of such acceleration.
