Execution Copy

1.

Payment of Interest.  Except as otherwise expressly provided herein or as specifically provided in the Note Purchase Agreement, the Principal Balance of this Note shall bear interest (computed on the basis of actual days elapsed in a 360-day year) at the rate of (i) eleven and fifty-eight hundredths percent (11.58%) per annum from the date hereof through and including September 30, 2010 and (ii) fifteen and fifty-eight hundredths percent (15.58%) per annum from October 1, 2010 and at all times thereafter (“Current Interest”).  In addition, default interest shall accrue on the unpaid Principal Balance of this Note at the rate of two percent (2%) per annum after the occurrence and during the continuance of an Event of Default.  Current Interest accruing on the Principal Balance of this Note shall be payable quarterly in arrears in accordance with the payment schedule on Exhibit A attached hereto and made a part hereof (assuming for purposes of Exhibit A that no portion of the Principal Balance of this Note is prepaid and that this Note is not accelerated prior to the Maturity Date).  In addition, all accrued and unpaid Current Interest on this Note (together with any accrued and unpaid default interest) shall be paid upon the payment in full of the entire outstanding Principal Balance of this Note (whether on the Maturity Date or as a result of the acceleration of the maturity thereof), or if a prepayment of this Note is made, on the Principal Balance prepaid, and, if payment in full is not paid when due, thereafter on demand.  Unless prohibited under applicable law, any accrued interest (whether Current Interest or default interest) which is not paid on the date on which it is due and payable shall be capitalized and shall bear interest at the same rate at which interest is then accruing on the Principal Balance of this Note until such interest is paid.  Any accrued interest (whether Current Interest or default interest) which for any reason has not theretofore been paid shall be paid in full on the date on which the final principal payment on this Note is made (whether on the Maturity Date or as a result of the acceleration of the maturity thereof).  Interest shall accrue on any payment due under this Note at the rates set forth herein until such time as payment therefor is actually delivered to the Holder.

2.

Payment of Principal on Note.

 

(a)

Scheduled Payments.  The Borrower shall pay the outstanding principal amount of this Note, together with all accrued and unpaid interest on the principal amount being repaid, on January 31, 2011 (the “Maturity Date”).

 

(b)

Optional Prepayments.  At any time after the second (2nd) anniversary of the Original Date of Issuance (or, in the event of an IPO or a sale of the Borrower approved by the Holder, at any time after the Original Date of Issuance), the Borrower, at its option, may prepay all or any portion of this Note on any scheduled quarterly payment date at a prepayment price of one hundred percent (100%) of the Principal Balance to be prepaid, plus accrued and unpaid interest to the prepayment date.

 

(c)

[Intentionally Omitted].

 

(d)

Notice of Prepayments.  The Borrower shall give notice (which shall be irrevocable) to the Holder of this Note of each prepayment not later than 1:00 p.m. (Chicago time) on the Business Day immediately preceding the date of prepayment, specifying the aggregate Principal Balance to be prepaid and the prepayment date.  Once any such notice has been given, the Principal Balance specified in such notice, together with all accrued and unpaid interest on the amount of each such prepayment to the date of payment, and any prepayment premium, shall become due and payable on such date of payment.

3.

Payment Schedule.  Set forth as Exhibit A attached hereto is a schedule which reflects the amount of Current Interest payable quarterly and the Principal Balance of this Note at the beginning and at the end of each quarter during the term of this Note (assuming for purposes of Exhibit A that no portion of the Principal Balance of this Note is prepaid and that this Note is not accelerated prior to the Maturity Date).  Upon any voluntary or mandatory prepayment of all or any portion of the Principal Balance, the Current Interest reflected on Exhibit A attached hereto shall be recomputed based upon the remaining Principal Balance.  The Holder shall amend Exhibit A hereto to reflect such recomputation and deliver the same to the Borrower, and such amended Exhibit A shall constitute rebuttable presumptive evidence of the Principal Balance owing and unpaid on this Note and the interest accruing and payable thereafter under this Note.  The failure to amend Exhibit A hereto or to deliver the same to the Borrower shall not, however, affect the obligations of the Borrower to pay the Principal Balance and all accrued and unpaid interest on the Principal Balance of this Note.

(a)

Transfer and Exchange.

 

(i)

Subject to any restrictions contained in this Note or the Note Purchase Agreement, this Note and all rights and obligations hereunder are transferable, in whole or in part, to any Person (excluding any Person that is a direct or indirect competitor of the Borrower), without charge to the Holder, upon surrender of this Note with a properly executed assignment in form and substance reasonably acceptable to the Borrower at the principal office of the Borrower.  To facilitate any such transfer, the Borrower hereby covenants to execute such documents and perform such acts as may be necessary or appropriate in the Holder’s sole judgment for the Holder to effect any such transfer.

Upon surrender of this Note for transfer or for exchange, the Borrower, at its expense, will (subject to the conditions set forth herein and in the Note Purchase Agreement) execute and deliver in exchange therefor a new Note or Notes, as the case may be, as requested by the Holder or transferee, which aggregates the Principal Balance of such Note, issued as the Holder or such transferee may request, dated so that there will be no gain or loss of interest on such surrendered Note and otherwise of like tenor.  The issuance of new Notes shall be made without charge to the Holder(s) of the surrendered Note for any issuance tax in respect thereof or other cost incurred by the Borrower in connection with such issuance.

8.

Governing Law.  This Note shall be governed and construed in accordance with the domestic laws of the State of Illinois, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Illinois or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Illinois.

9.

Liabilities.  In furtherance and not in limitation of the rights and remedies of the Holder of this Note hereunder or at law, the Holder of this Note may proceed under this Note against the Borrower in its absolute and sole discretion for any of the liabilities of the Borrower under this Note or any other liability or obligation of the Borrower arising hereunder.

Upon the occurrence of any “Event of Default,” as described and specified in the Note Purchase Agreement, the Holder shall have all of the rights and remedies in accordance with, and as provided by, the terms of the Note Purchase Agreement.  In addition, the Holder shall be entitled to recover from the Borrower any and all costs and expenses, including reasonable attorneys’ fees and court costs, incurred in enforcing its rights hereunder.

11.

Usury Laws.  It is the intention of the Borrower and the Holder of this Note to conform strictly to all applicable usury laws now or hereafter in force, and any interest payable under this Note shall be subject to reduction to an amount not in excess of the maximum legal amount allowed under the applicable usury laws as now or hereafter construed by the courts having jurisdiction over such matters.  If the maturity of this Note is accelerated by reason of an election by the Holder hereof resulting from an Event of Default, voluntary prepayment by the Borrower or otherwise, then the earned interest may never include more than the maximum amount permitted by law, computed from the date hereof until payment, and any interest in excess of the maximum amount permitted by law shall be canceled automatically and, if theretofore paid, shall at the option of the Holder hereof either be rebated to the Borrower or credited on the Principal Balance of this Note, or if this Note has been paid, then the excess shall be rebated to the Borrower.  The aggregate of all interest (whether designated as interest, service charges, points or otherwise) contracted for, chargeable, or receivable under this Note shall under no circumstances exceed the maximum legal rate upon the Principal Balance of this Note remaining unpaid from time to time.  If such interest does exceed the maximum legal rate, it shall be deemed a mistake and such excess shall be canceled automatically and, if theretofore paid, at the option of the Holder hereof either be rebated to the Borrower or credited on the Principal Balance of this Note, or if this Note has been repaid, then such excess shall be rebated to the Borrower.

12.

Waiver.  The Borrower hereby waives diligence, presentment, protest and demand and notice of protest and demand, dishonor and nonpayment of this Note, and expressly agrees that this Note, or any payment hereunder, may be extended from time to time and that the Holder hereof may accept security for this Note or release security for this Note, all without in any way affecting the liability of the Borrower hereunder.

13.

Section 163 of the Internal Revenue Code.  Notwithstanding any other provisions contained in this Note, payments under this Note shall not be deferred beyond any date if deferral beyond such date would result in this Note being treated as an “applicable high yield discount obligation” under Section 163(e)(5) and Section 163(i) of the Code.  The preceding sentence shall apply only to the extent necessary to achieve the objective herein described and shall apply only to amounts treated as interest or original issue discount under the Code.
