The assignment by the Secured Parties of their right, title, and interest with respect to the Obligations and the Loan Documents shall be at no expense (other than the payment of the applicable Purchase Price) to Guarantor other than the reimbursement by Guarantor of the reasonable out-of-pocket expenses of the Secured Parties (including their attorneys fees) in connection with documenting and effecting such assignment and the related delivery to Guarantor of the original Loan Documents in the possession of such Secured Parties. In connection with such assignment, the Secured Parties shall deliver to Guarantor any original Loan Documents and any Collateral in their possession and shall execute such other documents, instruments, and agreements reasonably necessary to effect such assignment, whereupon such Secured Parties shall be relieved from any further duties, obligations, or liabilities to Guarantor pursuant to this Agreement. For greater certainty, no Secured Party shall be under any obligation pursuant to this Agreement to approve any new credit facility or amend the terms of any existing credit facility for the account of the Guarantor or Heddle Marine Service Inc. for the purpose of assisting either of them to fund the Purchase Price. 3.04 Letter of Credit All payments made by a draw under the Letter of Credit shall reduce any amount due hereunder on a dollar for dollar basis.
