Washington, D.C. 20433 United States of America Re: Credit No. 2819 YEM (Transport Rehabilitation Project) Payment of Contracts Dear Sirs: We refer to Sections 2.20 through 2.26 of the Guidelines for Procurement under IBRD Loans and IDA Credits published by the International Development Association (the "Association") in May 1992. Until such time as the official rate of exchange of the Yemeni Rial is equivalent to the market rate of exchange, we agree that contracts to be financed by the Association under the above-referenced Credit will be entirely expressed in a currency or currencies widely used in international trade. Moreover, in the event that a portion of such contracts may be paid in Yemeni Rials, that portion shall not exceed the amount to be financed by us, which is 30% for Category (1) (a) of the table in paragraph 1 of Schedule 1 to the Credit Agreement of even date herewith, or 20% for Category (1) (b), and 5% for Categories 2 (a) and (b). We further agree that the market rate of exchange prevailing 28 days before bid opening (or in the event that such contract is not tendered, the market rate of exchange prevailing on the date of signature) shall apply for the purposes of calculating the payments for any portion of such contracts to be paid in Yemeni Rials. Furthermore, for contracts to be completed in excess of 12 months from the date of bid opening, the rate of exchange shall be adjusted annually to reflect the current market rate of exchange. Very truly yours, REPUBLIC OF YEMEN By /s/ Mohsin A. Alaini Authorized Representative CONFIRMED: INTERNATIONAL DEVELOPMENT ASSOCIATION By /s/ Inder K.
