PRELIMINARY STATEMENTS

1.The Applicant and the Bank are parties to that certain Letter of Credit and
Reimbursement Agreement, dated as of January 29, 2014 (as amended prior to the
date hereof, the “Existing Agreement”, as further amended by this Agreement, the
“Amended Agreement”, and as the Amended Agreement may hereafter be amended,
amended and restated, supplemented or otherwise modified from time to time, the
“Letter of Credit Agreement”). Capitalized terms used herein and not otherwise
defined herein shall have the meanings ascribed to such terms in the Amended
Agreement.
2.As of the date hereof, the aggregate stated amount of all outstanding Letters
of Credit issued by the Bank pursuant to the Existing Agreement is
$17,850,881.00. Pursuant to the Cash Collateral Agreement, all obligations of
the Applicant to the Bank under the Letter of Credit Agreement and such Letters
of Credit are secured by funds on deposit in the Account in an amount equal to
101% of the aggregate stated amount of such Letters of Credit (the “Required
Cash Collateral Balance”).
3.The Applicant has requested the Bank to withdraw and transfer to the Applicant
all funds on deposit in the Account and to accept in substitution therefor an
irrevocable standby letter of credit issued by Royal Bank of Canada in a stated
amount equal to the Required Cash Collateral Balance. In addition, the Applicant
desires to amend the Existing Agreement in certain particulars, including,
without limitation, to (i) modify the Termination Date, (ii) terminate the
ability for the Applicant to request additional Letters of Credit and (iii)
modify certain provisions in the Existing Agreement to reflect the substitution
of an irrevocable standby letter of credit for the funds on deposit in the
Account. The Bank has agreed to such withdrawal and transfer and such
amendments, to waive the requirements set forth in the Cash Collateral Agreement
regarding the maintenance of funds on deposit in the Account, and to authorize
BTMU pursuant to the Special Deposit Account Control Agreement to transfer all
funds on deposit in the Account to the Applicant, in each case, on the terms and
conditions set forth herein.
NOW, THEREFORE, in consideration of the premises and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto hereby agree as follows:
