       producers in Puerto Rico. It has an installed cement capacity of
       1.4MM metric tpy. PRC has a dry production process.

       PRC's ready-mix operations include 17 plants with national coverage.
       Sales volume in 2001 was 0.85 MM m3.

       Other businesses include aggregates, paper bags, gypsum,
       transportation, real estate and a financing company which in 2001
       represented less than 4% EBITDA.

Q:     What has been the evolution of cement demand in the past years? What
       is the sales mix bulk vs. bags?

A:     Cement demand in Puerto Rico has grown at a CAGR of 3.0% in the
       90-01 period. Sales volume in 2001 was 1.9 MM tons.

       55% of cement is sold in bulk.

Q:     How does Puerto Rico fit into your Caribbean market? What is your
       position in the region?

A:     CEMEX is a competitive player in the Caribbean market. The addition
       of PRC to the CEMEX portfolio would further consolidate CEMEX's
       position in this region.

       Important synergies in procurement, IT, etc., can be achieved by
       centralizing some of PRC operations into CEMEX's South and Central
       America & Caribbean operations.

Q:     What is the Enterprise Value of the company? What is the valuation
       multiple you are paying?

A:     The offer of $35/share implies an equity value for the company of
       US$180MM. Considering PRC's current net debt level of US$70MM, its
       enterprise value is US$250MM.

       For the EV/ton analysis, we are adjusting the EV to reflect only the
       cement business. We are assuming that on a steady-state basis, the
       cement business is responsible for 75% of the cash flows of the
       company, and therefore of the Enterprise Value of the company.

Q:     What are the major conditions for the successful completion of the
       tender offer? What is the timing for the tender offer and for the
       closing of the transaction?
