You have already received this proxy form along with other documents relating to the Meeting. Several proposals of extreme importance will be presented at the Meeting. Said proposals will provide you with more control over your shares since you will have the right to transfer them during your lifetime to your spouse and heirs, as long as they are either physicians or dentists. In addition, in case of death you will be able to transfer your shares to the person of your choosing even though the persons you choose are not physicians or dentists. At the same time, to assure that the Corporation remains under the control of physicians and dentists, the proposals provide that only shareholders that meet either of these two requirements have the right to vote. In order to implement the proposals, it is necessary to amend the By-laws and the Articles of Incorporation for which it is necessary that 75% of the issued and outstanding shares vote in their favor. I request your attendance to the Meeting so that this extraordinary majority can be achieved. If you cannot attend, I would appreciate if you could complete and remit to our attention the appropriate proxy form in order to move forward with these important Shareholder matters. For your convenience enclosed are a proxy form and a self stamped envelope. For any additional information you can contact Rosa M. Gonzalez, Manager of the Office of Shareholder Relations and Services at 787-277-6621 and 1-800-350-8552. Cordially, Valeriano Alicea Cruz, MD
