AGREEMENTS

In consideration of the recitals and the mutual covenants herein contained and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree that the Current Note Purchase Agreement (including all Schedules and Exhibits thereto) and the Current Collateral Documents shall be amended as of the date hereof as follows:

SECTION 1. SUPPLEMENT TO CURRENT NOTE PURCHASE AGREEMENT

Section 1.1. Description of Series 2012 Notes. The Issuers have authorized the issue and sale of $2,989,552 aggregate principal amount of their Senior Secured Guaranteed Notes, Series 2012, due June 1, 2017 (the “Series 2012 Notes”). The Series 2012 Notes shall be substantially in the form set out in Exhibit 1 hereto with such changes therefrom, if any, as may be approved by the Purchaser and the Issuers.

Section 1.2. Interest Rate. (a) The Series 2012 Notes shall bear interest (compounded semiannually and computed on the basis of a 360-day year of twelve 30-day months) on the unpaid principal thereof from the date of issuance at a rate equal to the 2012 Applicable Rate, payable as set forth in Exhibit 1, until such principal sum shall have become due and payable (whether at maturity, upon acceleration or otherwise), and thereafter, on any overdue payment of principal and Make-Whole Amount and, to the extent permitted by law, on any overdue interest and, during the continuance of an Event of Default, on such unpaid balance and on any overdue payment of any Make-Whole Amount, at a rate per annum from time to time equal to the Default Rate.

(b) The 2012 Applicable Rate for the Series 2012 Notes shall be determined by the Purchaser, and notice thereof shall be given to the Issuers, at least one Business Day immediately preceding the date of the 2012 Closing (hereinafter defined), together with a copy of the relevant screen used for the determination of the 2012 Applicable Rate and a calculation of the 2012 Applicable Rate, and any such determination made in accordance with the provisions of this

3

Amendment, shall be presumptively correct absent manifest error. As used herein the term “2012 Applicable Rate” means the rate per annum (rounded upwards, if necessary, to the next higher one hundred-thousandth of a percentage point) equal to 3.50% over the yield to maturity of the U.S. Treasury security with a maturity of June 1, 2017, which yield to maturity of the June 1, 2017 US Treasury security shall be determined using the ICUR function on the appropriate Bloomberg Financial Markets screen to interpolate between the appropriate on-the-run US Treasury securities, as at 11:00 a.m. (New York City time) at least one Business Day preceding the date of the 2012 Closing.

Section 1.3. Sale and Purchase of Series 2012 Notes. Subject to the terms and conditions hereof and as set forth in the Note Purchase Agreement and on the basis of the representations and warranties hereinafter set forth, the Issuers agree to issue and sell to the Purchaser, and the Purchaser agrees to purchase from the Issuers, the 2012 Notes in the principal amount set forth opposite the Purchaser’s name on Schedule A hereto at a price of 100% of the principal amount thereof on the closing date hereafter mentioned.

Section 1.4. Closing of Series 2012 Notes. The sale and purchase of the Series 2012 Notes to be purchased by the Purchaser shall occur at the offices of Chapman and Cutler LLP, 111 West Monroe Street, Chicago, Illinois 60603 at 10:00 a.m. Chicago time, at a closing (the “2012 Closing”) on October 24, 2012 or on such other Business Day thereafter on or prior to October 24, 2012 as may be agreed upon by the Issuers and the Purchaser. At the 2012 Closing, the Issuers will deliver to the Purchaser the Series 2012 Notes to be purchased by the Purchaser in the form of a single Series 2012 Note (or such greater number of Series 2012 Notes in denominations of at least $100,000 as such Purchaser may request) dated the date of the 2012 Closing and registered in the Purchaser’s name (or in the name of the Purchaser’s nominee), against delivery by the Purchaser to the Issuers or their order of immediately available funds in the amount of the purchase price therefor by wire transfer of immediately available funds for the account of the Issuers as designated by the Issuers in, and otherwise in accordance with, the Funding Instruction Letter delivered to the Purchaser at least three Business Days prior to the date of the 2012 Closing pursuant to Section 4.9 of the Note Purchase Agreement (such condition being applicable to the Series 2012 Notes as specified in Section 5(l) hereof). If, at the 2012 Closing, the Issuers shall fail to tender such Series 2012 Notes to the Purchaser as provided above in this Section 1.4, or any of the conditions specified in Section 1.6 or Section 5 shall not have been fulfilled to the Purchaser’s satisfaction, the Purchaser shall, at its election, be relieved of all further obligations under this Amendment, without thereby waiving any rights the Purchaser may have by reason of such failure or such nonfulfillment.

Section 1.5. Representations of the Purchaser. The Purchaser represents and warrants that the representations and warranties set forth in Section 6 of the Note Purchase Agreement are true and correct on the date hereof with respect to the purchase of the Series 2012 Notes by the Purchaser.

4

Section 1.6. Conditions to 2012 Closing. The obligation of the Purchaser to purchase and pay for the Series 2012 Notes to be sold to the Purchaser at the 2012 Closing is subject to the fulfillment to the Purchaser’s satisfaction, prior to the 2012 Closing, of the conditions set forth in Section 5 of this Amendment.

8

Agreements when and as the same shall become due and payable, whether by lapse of time, upon redemption or prepayment, by extension or by acceleration or declaration, or otherwise, (B) the full and prompt performance and observance by the 2011 Notes Obligors of each and all of the covenants and agreements required to be performed or observed by such Persons under the terms of the Financing Agreements, and (C) payment, upon demand by any holder of the Series 2011 Notes, of all costs and expenses, legal or otherwise (including reasonable attorneys fees) and such expenses, if any, as shall have been expended or incurred in the protection or enforcement of any right or privilege under the Financing Agreements or this Guarantee Agreement or in any consultation or action in connection therewith, and in each and every case irrespective of the validity, regularity, or enforcement of any of the Financing Agreements or any of the terms thereof or of any other like circumstance or circumstances (all of the obligations described in the foregoing clause (A), clause (B) and clause (C) being referred to herein as the “2011 Notes Guaranteed Obligations”).

Each Guarantor agrees as a primary obligation to indemnify each Noteholder from time to time on demand from and against any loss incurred by it as a result of any Financing Agreement being or becoming void, voidable or unenforceable for any reason whatsoever, whether or not known to such Noteholder, the amount of such loss being the amount which such Noteholder would otherwise have been entitled to recover from the Guarantor.

SECTION 5. CONDITIONS PRECEDENT.

This Amendment shall become effective on, and the Purchaser’s obligation to purchase and pay for the Series 2012 Notes to be sold to it at the 2012 Closing shall not be effective until, the Business Day when each of the following conditions shall have been satisfied (the “Effective Date”):

(b) The Purchaser shall have consented to this Amendment as evidenced by its execution hereof.

(c) The representations and warranties of the Obligors set forth in Section 6 hereof shall be true and correct in all material respects as of the date of the execution and delivery of this Amendment and as of the Effective Date.

(j) The Purchaser shall have received a date down endorsement to the ALTA Policy, indicating that since the original date of Closing of the Series 2011 Notes there has been no change in the status of title as shown on the ALTA Policy, which date down endorsement shall have the effect of advancing the effective date of the policy to the date of the 2012 Closing and increasing the coverage of the policy by an amount equal to the funding then being made under the Series 2012 Notes. The Company shall have delivered, or shall have caused to be delivered, such documents and other deliveries as requested by the title insurance company in order for it to issue an endorsement to the ALTA Policy as provided in this paragraph (j).
