Dear Sirs,

  We refer to the contract No．4632 covering 500 dozen track suits.

  We wish to remind you that we have had no news from you about shipment of the goods.

  As we mentioned in our last letter, we are in urgent need of the goods and we may be compelled to seek an alternative source of supply.

  Under the circumstances, it is not possible for us to extend further our letter of credit No．1492, which expires on 21 August．Please understand how serious and urgent it is for us to resolve this matter.

  We look forward to receiving your shipping advice, by fax, within the next seven days.

                                      Yours faithfully,
