       1. The name of the Corporation is Isotope Solutions Group, Inc. (the
"Corporation").

       2. The purpose of the Corporation is to engage in any lawful act or
activity for which a corporation may be organized under the Business Corporation

the consent or approval of any New York State official, department, board,
agency or other body without such consent or approval first being obtained.

       3. The office of the Corporation is to be located in the County of
Nassau.

issue is 51,000,000 shares, of which 50,000,000 shares shall be common stock,
par value $.001 per share, and 1,000,000 shares shall be preferred stock, par
value $ .001 per share.

          (a) The directors are expressly granted authority to provide for the
issue of any or all shares of the preferred stock, in one or more series, and to
fix for each such series such voting powers, full or limited, and such
designations, preferences and relative, participating, optional or other special
rights and such qualifications, limitations or restrictions thereof, including
one or more series of shares that do not share ratably with each other in the
payment of dividends and other distributions, as shall be stated and expressed
in the resolution or resolutions adopted by the directors providing for the
issue of such series (a "Preferred Stock Designation") and as may be permitted
by the Business Corporation Law.

          (b) Except as otherwise required by law and except as otherwise
provided in any Preferred Stock Designation, the holders of common stock shall
possess exclusively all voting power of the Corporation. Each share of common
stock shall have one vote. Shareholders shall not have pre-emptive rights or be
entitled to cumulative voting in connection with the shares of the Corporation's
common stock or preferred stock.

       5. Whenever shareholders are required or permitted to take any action by
vote, such action may be taken without a meeting by written consent, setting
forth the action so taken, signed by the holders of outstanding shares having
not less than the minimum number of votes that would be necessary to authorize
or take such action at a meeting at which all shares entitled to vote thereon
were present and voted. Prompt notice of the taking of any such action in such
manner shall be given to those shareholders who have not consented in writing.


                                       2


       6. The Secretary of State is designated as the agent of the Corporation
upon whom process against the Corporation may be served, and the address to

       7. The following provisions are inserted for the management of the
business and for the conduct of the affairs of the Corporation and for further
definition, limitation and regulation of the powers of the Corporation and of
its directors and shareholders:

          (a) Election of directors need not be by written ballot unless the
by-laws of the Corporation so provide.

          (b) The board of directors or the shareholders shall have the power to
make, adapt, amend or repeal the by-laws of the Corporation.

          (c) The directors in their discretion may submit any contract or act
for approval or ratification at any annual meeting of the shareholders or at any
meeting of the shareholders called for the purpose of considering any such act
or contract, and any contract or act that shall be approved or be ratified by
the vote of the holders of a majority of the stock of the Corporation that is
represented in person or by proxy at such meeting and entitled to vote thereat
(provided that a lawful quorum of shareholders be there represented in person or
by proxy) shall be valid and binding upon the Corporation and upon all the
shareholders as though it had been approved or ratified by every shareholder of
the Corporation, whether or not the contract or act would otherwise be open to
legal attack because of directors' interest, or for any other reason.

          (d) Any vacancy in the board of directors arising by reason of removal
of one or more directors without cause may be filled by the board.

          (e) In addition to the powers and authorities hereinbefore or by
statute expressly conferred upon them, the directors are hereby empowered to
exercise all such powers and do all such acts and things as may be exercised or
done by the Corporation; subject, nevertheless, to the provisions of the
statutes of the State of New York, to the provisions of this Certificate of
Incorporation, and to any by-laws from time to time made by the shareholders;
provided, however, that no by-law so made shall invalidate any prior act of the
directors that would have been valid if such by-law had not been made.

       8. The personal liability of the directors of the Corporation is hereby
eliminated to the fullest extent permitted by the Business Corporation Law or
any successor statute.



                                       3


       9. The Corporation shall indemnify its officers and directors, to the
fullest extent permitted by law, including, but not limited to, the provisions
of Sections 721 through 726 of the Business Corporation Law, as the same may be
amended and supplemented from time to time, and shall pay the expenses incurred
by any such officer or director of the Corporation claiming to be entitled to
indemnification in any action or proceeding in advance of the final disposition
of such action or proceeding to the fullest extent permitted by law, including,
without limitation, the provisions of Section 723(c) of the Business Corporation
Law, as it may be amended and supplemented from time to time.

written consent, setting forth the action so taken, of the directors of the
Corporation pursuant to Section 708(b) of the New York Business Corporation Law,
and by the vote of the holders of a majority of the shares present or
represented by proxy at a meeting of the shareholders of the Corporation held on
