ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    There are no statutory provisions under applicable Dominican law for the
indemnification or insuring of directors and officers against liability.

    Pursuant to Dominican law, shareholders are asked to vote upon the
performance of management at annual shareholders' meetings. The Company's
vigilance officer delivers a report on the financial performance of the Company
and other issues related to management's performance. If the holders of a
majority of the votes entitled to be cast approve management's performance, all
shareholders are deemed to have released the directors and officers from claims
or liability to the Company or its shareholders arising out of actions taken or
any failure to take actions by any of them on behalf of the Company during the
prior fiscal year, with certain exceptions, and shareholders will likely fail in
any suit brought in a Dominican court with respect to such acts or omissions.
Officers and directors may not be released from any claims or liability for
criminal acts, fraud, self-dealing or gross negligence. If the shareholders do
not approve management's performance, the vigilance officer's report may form
the basis of any suit brought by the shareholders against the officers and
directors of the Company.

    Article 48 of the Company's by-laws provides that the Company shall
indemnify any person made or threatened to be made a party to any action, suit
or proceeding, whether civil, criminal, administrative or investigative, by
reason of the fact that such person, or a person of whom he or she is the legal
representative, is or was a director, officer, employee or agent of the Company
or any predecessor of the Company, or serves or served any other enterprise as a
director, officer, employee or agent at the request of the Company or any
predecessor of the Company.

    The Company shall pay any expenses reasonably incurred by a director or
officer in defending any civil, criminal, administrative or investigative
action, suit or proceeding in advance of the final disposition of such action,
suit or proceeding upon receipt of an undertaking by or on behalf of such
director or officer to repay such amount if it shall ultimately be determined
that he or she is not entitled to be indemnified by the Company under
Article 48 or otherwise. The Company may, by action of its Board of Directors,
provide for the payment of such expenses incurred by employees and agents of the
Company as it deems appropriate.

ITEM 17. UNDERTAKINGS.

    (a) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

    (b) The undersigned registrant hereby undertakes that:

        (1) For purposes of determining any liability under the Securities Act
    of 1933, the information omitted from the form of prospectus filed as part
    of this registration statement in reliance upon Rule 430A and contained in a
    form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
    (4) or 497(h) under the Securities Act shall be deemed to be part of this
    registration statement as of the time it was declared effective.

        (2) For the purpose of determining any liability under the Securities
    Act of 1933, each post-effective amendment that contains a form of
    prospectus shall be deemed to be a new registration statement relating to
    the securities offered therein, and the offering of such securities at that
    time shall be deemed to be the initial bona fide offering thereof.

                                      II-2

                                   SIGNATURES


    Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form F-3 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Santo Domingo, Dominican Republic on April 11, 2000.
