upon the conditions set forth herein, each Selling Stockholder agrees to
sell, assign, transfer and deliver to

                                   -1-
<PAGE>
the Company, and the Company agrees to purchase from each Selling
Stockholder, at the Closing (as defined below), the Viper Shares owned by
the respective Selling Stockholder as set forth on Exhibit A attached

each Selling Stockholder a pro rata share of the Company Shares, as
determined according to Section 1.1(a) below.

               (a)  DETERMINATION OF PRO RATA SHARE OF COMPANY SHARES.  The
number of Common Company Shares which each Selling Stockholder is entitled
to receive hereunder shall be determined by multiplying the total number of
Company Shares (i.e., 36,000,000) by a fraction, the numerator of which is
the total number of Viper Shares owned by the Selling Stockholder at the
Closing and the denominator of which is the total number of Viper Shares
issued and outstanding at the Closing (i.e., 3,000,000).

          1.2  INSTRUMENTS OF TRANSFER.

               (a)  VIPER SHARES.  Each Selling Stockholder shall deliver
to the Company original certificates evidencing the Viper Shares along with
executed stock powers, in form and substance satisfactory to the Company,
for purposes of assigning and transferring all of their right, title and
interest in and to the Viper Shares.  From time to time after the Closing
Date, and without further consideration, the Selling Stockholders will
execute and deliver such other instruments of transfer and take such other
actions as the Company may reasonably request in order to facilitate the
transfer to the Company of the securities intended to be transferred
hereunder.

               (b)  THE COMPANY SHARES.  The Company shall deliver to the
Selling Stockholders on the Closing Date original certificates evidencing
the Company Shares or in the alternative an authorized Treasury Order to
the Company's Transfer Agent for the same, in form and substance
satisfactory to the Selling Stockholders, in order to effectively vest in
the Selling Stockholders all right, title and interest in and to the
Company Shares.  From time to time after the Closing Date, and without
further consideration, the Company will execute and deliver such other
instruments and take such other actions as the Selling Stockholders may
reasonably request in order to facilitate the issuance to them of the
Company Shares.

          1.3  CLOSING.  The closing ("Closing") of the exchange of the
Viper Shares and the Company Shares shall take place at the offices of
Viper at 10:00 a.m., local time, on November 15, 2000, or at such other
time and place as may be agreed to by all of the parties hereto ("Closing
Date").

          1.4  TAX FREE REORGANIZATION.  The parties intend that the

with the Company with respect to himself, as follows:

                                   -3-
<PAGE>
          3.1  POWER AND AUTHORITY.  The Selling Stockholder has all
requisite individual power and authority to enter into and to carry out all
of the terms of this Agreement and all other documents executed and
delivered in connection herewith (collectively, the "Documents").  All
individual action on the part of the Selling Stockholder necessary for the
authorization, execution, delivery and performance of the Documents by the
Selling Stockholder has been taken and no further authorization on the part
of the Selling Stockholder is required to consummate the transactions
provided for in the Documents.  When executed and delivered by the Selling
Stockholder, the Documents shall constitute the valid and legally binding
obligation of the Selling Stockholder enforceable in accordance with their
respective terms, except as limited by applicable bankruptcy, insolvency
reorganization and moratorium laws and other laws affecting enforcement of
creditor's rights generally and by general principles of equity.

          3.2  OWNERSHIP OF AND TITLE TO SECURITIES.  The Selling
Stockholder represents that he is the sole owner of the Viper Shares held
by him and that there are no warrants, options, subscriptions, calls, or
other similar rights of any kind for the issuance or purchase of any of the
Viper Shares or other securities of Viper held by the Selling Stockholder.
The Selling Stockholder represents that the Selling Stockholder has and
will transfer to the Company good and marketable title to the Viper Shares
which he owns, free and clear of all pledges, security interests,
mortgages, liens, claims, charges, restrictions or encumbrances.

          3.3  INVESTMENT AND RELATED REPRESENTATIONS.  The Selling
Stockholder is aware that neither the Company Shares nor the offer or sale
thereof to the Selling Stockholder has been registered under the Securities
Act of 1933, as amended ("Act"), or under any state securities law.  The
Selling Stockholder understands that the Company Shares will be
characterized as "restricted" securities under federal securities laws
inasmuch as they are being acquired in a transaction not involving a public
offering and that under such laws and applicable regulations such
securities may be resold without registration under the Act only in certain
limited circumstances.  The Selling Stockholder agrees that the Selling
Stockholder will not sell all or any portion of the Company Shares except
pursuant to registration under the Act or pursuant to an available
exemption from registration under the Act.  The Selling Stockholder
understands and acknowledges that all certificates representing the Company
Shares shall bear the following legend or a legend of similar import and
that the Company shall refuse to transfer the Company Shares except in
accordance with such restrictions:

          "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT
          BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
          AMENDED (THE "ACT"), OR UNDER CERTAIN STATE SECURITIES
          LAWS.  NO SALE OR TRANSFER OF THESE SHARES MAY BE MADE
          IN THE ABSENCE OF (1) AN EFFECTIVE REGISTRATION
          STATEMENT UNDER THE ACT OR (2) AN OPINION OF COUNSEL
          THAT REGISTRATION UNDER THE ACT OR UNDER APPLICABLE
          STATE SECURITIES LAWS IS NOT REQUIRED IN CONNECTION
          WITH SUCH PROPOSED SALE OR TRANSFER."
