This Amendment No. 2 (this "Amendment No. 2") to the Tender Offer Statement
on Schedule TO (the "Schedule TO"), filed initially with the Securities and
Exchange Commission on July 1, 2002, relates to the offer by Tricem
Acquisition, Corp. (the "Purchaser"), a Puerto Rico corporation and an
indirect wholly owned subsidiary of CEMEX, S.A. de C.V., a company
organized under the laws of the United Mexican States ("CEMEX"), to
purchase all outstanding shares of common stock of Puerto Rican Cement
Company, Inc., a Puerto Rico corporation (the "Company"), par value $1.00
per share (the "Shares"), at U.S. $35.00 per share, net to the seller in
cash, without interest thereon, upon the terms and subject to the
conditions set forth in the Offer to Purchase, dated July 1, 2002 (the
"Offer to Purchase"), and in the related Letter of Transmittal (which,
together with any amendments or supplements thereto, constitute the
"Offer"), which were filed as Exhibits (a)(1) and (a)(2), respectively, to
the Schedule TO. Unless otherwise defined herein, all capitalized terms
used herein shall have the respective meanings given such terms in the
Offer to Purchase.

Item 7. Source and Amount of Funds or Other Consideration.

         (a)-(b), (d) Item 7 of the Schedule TO, which incorporates by
         reference certain information contained in the Offer to Purchase,
         hereby is amended and supplemented as follows:

                  The subsection entitled "Source and Amount of Funds" of
                  the Offer to Purchase hereby is amended and supplemented
                  with the following information:

                           On July 15, 2002, CEMEX executed two promissory
                  notes in favor of BBVA Bancomer, S.A., Institucion de
                  Banca Multiple, Grupo Financiero, BBVA Bancomer, S.A.,
                  Grand Cayman Branch, British West Indies in the principal
                  amounts of U.S. $180 million and U.S. $30 million,
                  respectively. The promissory note in the principal amount
                  of U.S. $180 million matures on January 10, 2003 and bears
                  interest at a rate per annum equal to 2.67%. The
                  promissory note in the principal amount of U.S. $30 million
                  matures on September 30, 2002 and bears interest at a
                  rate per annum equal to 2.61%. The promissory notes are
                  filed as Exhibits (b)(1) and (b)(2) to this Amendment No.
                  2 and are incorporated by reference herein.

                           The proceeds of the promissory notes will be
                  contributed or loaned through several subsidiaries of
                  CEMEX to the Purchaser, which will use such proceeds to
                  purchase shares in the Offer and the Merger and to pay
                  related fees and expenses. In addition, the Purchaser may
                  use a portion of such proceeds to repay a portion of the
                  Company's long term indebtedness and bank credit lines
                  concurrently with or following the consummation of the
                  Offer or the Merger.

                           CEMEX and its subsidiaries, including the
                  Purchaser, expect to repay such amounts borrowed under
                  the promissory notes through internally generated free
                  cash flow.

                           No alternative financing plans or arrangements
                  have been made in the event that CEMEX or its
                  subsidiaries making capital contributions and loans to
                  the Purchaser are unable to borrow the amounts
                  anticipated under these promissory notes. In the event
                  that financing is unavailable under these promissory
                  notes or any alternative financing or arrangement, it is
                  anticipated that all of the funds necessary to consummate
                  the Offer and the Merger would come from capital
                  contributions or intra-company loans to the Purchaser
                  from subsidiaries of CEMEX, which in turn would be funded
                  from CEMEX's internally generated free cash flow.
