                                    RESTATED
                          CERTIFICATE OF INCORPORATION
                                       OF
                         LASER MEDICAL TECHNOLOGY, INC.

               Laser Medical Technology, Inc. (the "Corporation"), a corporation
organized and existing under the laws of the State of Delaware, hereby certifies
as follows:

               1. The name of the Corporation was Endo Technic International
Corporation. Endo Technic International Corporation was originally incorporated
as Pamplona Capital Corp., and the original Certificate of Incorporation of the
Corporation was filed with the Secretary of State of the State of Delaware (the
"Delaware Secretary") on February 10, 1987. A Certificate of Amendment of the
Restated Certificate of Incorporation was filed with the Delaware Secretary on
March 2, 1992, which amendment changed the name of the Corporation to Laser
Medical Technology, Inc. and reflected a one for two reverse stock split.
Another Certificate of Amendment was filed with the Delaware Secretary on June
14, 1993, which amendment restricted revision of the Bylaws and made provisions
for a staggered Board of Directors. A Restated Certificate of Incorporation was
filed with the Delaware Secretary on February 15, 1994, effecting a one-for-four
reverse stock split.

               2. This Restated Certificate of Incorporation restates,
integrates and amends the Certificate of Incorporation of this Corporation.

liable for monetary damages to the Corporation or its stockholders for breach of
any fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to the Corporation or its stockholders; (ii) for acts

                                       2

               SEVENTH: A director or officer of the Corporation shall not be
disqualified by his or her office from dealing or contracting with the
Corporation as a vendor, purchaser, employee, agent or otherwise. No
transaction, contract or act of the Corporation shall be void or voidable or in
any way affected or invalidated by reason of the fact that any director or
officer of the Corporation is a member of any firm, a stockholder, director or
officer of any corporation or trustee or beneficiary of any trust that is in any
way interest in such transaction, contract or act. No director or officer shall
be accountable or responsible to the Corporation for or in respect to any
transaction, contract or act of the Corporation or for any gain or profit
directly or indirectly realized by him or her by reason of the fact that he or
she or any firm in which he or she is a member of any corporation of which he or
she is stockholder, director, or officer, or any trust of which he or she is a
trustee, or beneficiary, is interested in such transaction, contract or act;
provided the fact that such director or officer or such firm, corporation,
trustee, or beneficiary of such trust, is so interested shall have been
disclosed or shall have been known to the members of the Board of Directors as
shall be present at any meeting at which action upon such contract, transaction
or act shall have been taken. Any director may be counted in determining the
existence of quorum at any meeting of the Board of Directors which shall
authorize or take action in respect to any such contract, transaction or act,
and may vote to authorize, ratify or approve any such contract, transaction or
act, and any officer of the Corporation may take any action within the scope of
his or her authority, respecting such contract, transaction or act with like
force and effect as if he or she or any firm of which he or she is a member, or
any corporation of which he or she is a stockholder, director or officer or any
trust in which he or she is a trustee or beneficiary, were not interested in
such transaction, contract or act. Without limiting or qualifying the foregoing,
if in any judicial or other inquiry, suit, cause or proceeding, the question of
whether a director or officer of the Corporation has acted in good faith is
material, and notwithstanding any statute or rule of law or equity to the
contrary (if any there be) his or her good faith shall be presumed in the
absence of proof to the contrary by clear and convincing evidence.

               EIGHTH: In furtherance and not in limitation of the powers
conferred by the laws of the State of Delaware, the Board of Directors of the
Corporations expressly authorized and empowered to make, alter and repeal the
Bylaws of the Corporation, subject to the power of the stockholders of the
Corporation to alter or repeal any Bylaw made by the Board of Directors.

               NINTH: Whenever a compromise or arrangement is proposed between
the Corporation and its creditors or any class of them and/or between the
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of the Corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for the Corporation under the
provisions of Section 291 of Title 8 of the Delaware Code or on the application
of trustees in dissolution or of any receiver or receivers appointed for the
Corporation under the provisions of Section 279 of Title 8 of the Delaware Code,
order a meeting of the creditors or class of creditors, and/or of the
stockholders or class of stockholders of the Corporation, as the case may be, to
be summoned in such manner as the said court directs. If a majority in number
representing three-fourths in value of the creditors or class of creditors,
and/or of the stockholders or class of stockholders of the Corporation, as the
case may be, agree to any compromise or arrangement and to any reorganization of
this Corporation as consequence of such compromise or arrangement, the said
compromise or arrangement and the said reorganization shall, if sanctioned by
the court to which the said application has been made, be binding on all the
creditors or class of creditors, and/or on all the stockholders or class of
stockholders, of the Corporation, as the case may be, and also on the
Corporation.
