“(iv)

(A) Seller agrees that it shall not withdraw the Shell L/C for a period of 24 months after the Closing Date, unless Buyer notifies Seller that it may withdraw the Shell L/C prior to the end of such 24-month period; provided, however, that Seller may agree to terminate the Shell L/C or reduce the amount of the Shell L/C at any time to the extent authorized to do so by Shell Trading (US) Company or any court of competent jurisdiction. Buyer shall reimburse Seller with respect to any draw under the Shell L/C within two Business Days of Seller’s written request for reimbursement.

First Amendment to Stock Purchase Agreement

(B) Subject to Buyer’s compliance with the following provisions of this Section 3.2(e)(iv), Seller shall leave in place the letters of credit listed on Schedule 3.2(e) (each such letter of credit being a “Seller L/C”) until the earlier of 60 days after the Closing Date or the expiration date of each respective Seller L/C as listed on Schedule 3.2(e).

(C) At the Closing, Buyer shall, or shall cause Lion Oil Trading & Transportation to, provide irrevocable standby letters of credit for the benefit of Seller (each such letter of credit being a “Buyer L/C”), each of which shall be a back-up letter of credit to a corresponding Seller L/C. Each Buyer L/C shall (i) be issued by a nationally recognized U.S. banking institution acceptable to Seller, (ii) be in a form acceptable to Seller, including a face amount equal to the face amount of the corresponding Seller L/C, (iii) set forth Seller as the sole beneficiary, and (iv) provide that Seller is entitled to draw upon such Buyer L/C if and to the extent the corresponding Seller L/C is drawn upon and (v) have an expiration date not less than 10 days after the expiration date of its corresponding Seller L/C; provided, however, the Buyer L/C corresponding to the Seller L/C-Chevron and the Seller L/C-Trafigura (April) (both defined in Schedule 3.2(e)) shall have an expiration date of June 3, 2011, the Buyer L/C corresponding to the Seller L/C-Trafigura (May) (defined in Schedule 3.2(e)) shall have an expiration date of July 10, 2011, and the Buyer L/C corresponding to the Seller L/C-Saudi Oil (defined in Schedule 3.2(e)) shall have an expiration date of June 3, 2011; provided, further, that the Buyer L/C corresponding to the Seller L/C-Trafigura (April) shall be for a face amount that is $250,000 less than the face amount of the Seller L/C-Trafigura (April), and in consideration of that differential, Buyer shall pay to Seller $250,000 at the Closing, to be held as a deposit which may be applied by Seller to offset, on a dollar-for-dollar basis and to the extent of such deposit, any draws upon the Seller L/C-Trafigura (April) (with any amounts not so applied to be returned by Seller to Buyer within five Business Days following the expiration of the Seller L/C-Trafigura (April) pursuant to its terms).

(D) Buyer agrees to indemnify, defend and hold Seller harmless from and against any Claims or Losses in the event and to the extent any Seller L/C is drawn upon by the beneficiary thereof and Seller does not immediately receive cash from the corresponding Buyer L/C, in an amount equal to the draw under such Seller L/C.
