  Each Warrant represented hereby is exercisable at the option of the Registered
Holder, but no fractional shares of Common Stock will be issued.  In the case of
the exercise of less than all the Warrants represented hereby, the Company shall
cancel the Warrant Certificate upon the surrender hereof and shall execute and
deliver a new Warrant Certificate or Warrant Certificates of like tenor, which
the Warrant Agent shall countersign, for the balance of such Warrants.

  This Warrant shall not be exercisable by a Registered Holder in any state
where such exercise would be unlawful.

  This Warrant Certificate is exchangeable, upon the surrender hereof by the
Registered Holder at the corporate office of the Warrant Agent, for a new
Warrant Certificate or Warrant Certificates of like tenor representing an equal
aggregate number of Warrants, each of such new Warrant Certificates to represent
such number of Warrants as shall be designated by such Registered Holder at the
time of such surrender.  Upon due presentment with any tax or other governmental
charge imposed in connection therewith, for registration of transfer of this
Warrant Certificate at such office, a new Warrant Certificate or Warrant
Certificates representing an equal aggregate number of Warrants will be issued
to the transferee in exchange thereof, subject to the limitations provided in
the Warrant Agreement.

  The Company has agreed to register the shares issuable upon exercise of the
Warrants under certain conditions as set forth in the Warrant Agreement.

  The Company agrees at all times to reserve or hold available a sufficient
number of Common Shares to cover the number of shares issuable upon the exercise
of this and all other Warrants or like tenor then outstanding.

  Prior to the exercise of any Warrant represented hereby, the Registered Holder
shall not be entitled to any rights of a shareholder of the Company, including,
without limitation, the right to vote or to receive any notice of any
proceedings of the Company.  No dividends shall be payable or accrue in respect
of this Warrant or the interest represented hereby or the shares purchasable
hereunder until or unless, and except to the extent that, this Warrant shall be
exercised.

  Except as otherwise above provided, this Warrant and all rights hereunder are
transferable by the Registered Holder hereof in person or by duly authorized
attorney on the books of the Company upon surrender of this Warrant, properly
endorsed to the Company, only after approval by the Board of Directors of the
Company.

  The Company may deem and treat the registered owner of this Warrant at any
time as the absolute owner hereof for all purposes and shall not be affected by
any notice to the contrary.

  If at any time or from time to time the Company shall declare a stock dividend
or, by subdivision, consolidation, or reclassification of shares, or otherwise,
change as a whole the outstanding Common Shares into a different number of a
class of shares, the number and class of shares so changed shall, for the
purposes of this Warrant and the terms and conditions hereof, replace the shares
outstanding immediately prior to such change, and the Warrant purchase price in
effect, and the number of shares purchasable under this Warrant, immediately
prior to the date upon which such change shall become effective, shall be
proportionately adjusted.  Irrespective of any adjustment or change in the
Warrant purchase price or the number of Common Shares actually purchasable under
this or any other Warrant of like tenor, the Warrants theretofore and thereafter
issued may continue to express the Warrant purchase price per share and the
number of shares purchasable thereunder as the Warrant purchase price per share
and the number of shares purchasable were expressed upon the Warrants when
initially issued.

  Upon the happening of any event requiring an adjustment of the Warrant
purchase price hereunder, the Company shall forthwith give written notice
thereof to the Registered Holder stating the adjusted 

                                       2

Warrant purchase price and the adjusted number of Common Shares purchasable upon
the exercise hereof resulting from such event and setting forth in reasonable
detail the method of calculation and the facts upon which such calculation is
based, The Board of Directors of the Company shall determine the computation
made hereunder. In case any voluntary or involuntary dissolution, liquidation,
or winding up of the Company shall at any time be proposed, the Company shall
give at least 20 days' prior written notice thereof to the Registered Holder
stating the date on which such event is to take place and the date (which shall
be at least 20 days after the giving of such notice) as of which the holders of
Common Shares of record shall be entitled to exchange their Common Shares for
securities or other property deliverable upon such dissolution, liquidation, or
winding up (on which date, in the event such dissolution, liquidation, or
winding up shall actually take place, this Warrant and all rights with respect
hereto shall terminate). Notices pursuant to this paragraph shall be given by
first class mail, postage prepaid, addressed to the registered holder of this
Warrant at the address of such holder appearing in the records of the Company.

  For the purposes of the foregoing paragraphs, the term "Common Shares" shall
include the aggregate number of shares that the Company, by its Articles of
Incorporation, as from time to time amended, is authorized to issue, which are
not limited to a fixed sum or percentage of the par value in respect of the
rights of the holders thereof to participate in dividends or in distribution of
assets upon the voluntary or involuntary liquidation, dissolution, or winding up
of the Company.

  Any conflict in the terms of this Warrant Certificate and the terms of the
Warrant Agreement shall be resolved with reference to the terms of the Warrant
Agreement.  This Warrant Certificate shall be governed by and construed in
accordance with the laws of the State of Delaware.

  IN WITNESS WHEREOF, the Company has caused this Warrant Certificate to be duly
executed by its duly authorized officer and its corporate seal to be imprinted
hereon this 29th day of October, 1997.
