Buyer or a Buyer Subsidiary) or other form of collateral (including, a letter of
credit, performance or surety bond, cash deposit or otherwise) from or supported

sentence, provided Seller shall not take any actions in connection herewith (nor
request that Buyer take any action) that would result in an adverse effect under
any such Supported Contract. At and following Closing, and Buyer shall and shall
cause the applicable Companies and the applicable Subsidiaries (A) to indemnify
Parent and its Affiliates from and against any and all Damages actually incurred
by any of them relating to any payment obligation under any Company Surviving
Supported Arrangements that are outstanding at Closing and under the Company

not to (x) amend or modify the terms of any Company Surviving Supported
Arrangement if such amendment or modification would reasonably be expected to
materially increase the likelihood that the applicable Company Surviving
Supported Arrangement would be drawn, paid, or called upon). Notwithstanding the
foregoing, Buyer shall use its commercially reasonable efforts to obtain a
release of the Seller Group of the Company Surviving Supported Arrangement set
forth on Schedule 3.16(a)(i) in the form set forth in Schedule 3.16(a)(ii) and
deliver a replacement surety bond in the amount of $12,730,549 to the same
