     WHEREAS, the Company is also conducting a media financing in the amount of

Agreement, as more particularly described herein.

     NOW, THEREFORE, the parties agree to the following terms and conditions:

longer required under the applicable requirements of the Act, the Shares shall
bear the following legend:

          "THE SECURITY (OR ITS PREDECESSOR) EVIDENCED HEREBY WAS ORIGINALLY
          ISSUED PURSUANT TO REGULATION D IN A TRANSACTION EXEMPT FROM


                                      2


          REGISTRATION UNDER SECTION 5 OF THE UNITED STATES SECURITIES ACT OF
          1933 (THE "SECURITIES ACT"), AND THE SECURITY EVIDENCED HEREBY MAY NOT
          BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH
          REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM ABOVE."

     Within 30 days of the Closing, the Company agrees to commence the

registration expenses (exclusive of underwriting discounts and commissions) of
the Registration Statement shall be borne by the Company, except that the
expenses borne by the Company shall not include the expenses of any experts
retained by the selling holders, any selling commissions or discounts, nor shall
they include the fees of more than one counsel for all selling holders, whose
fee shall not exceed $15,000 for any registration. Upon completion of the
registration of the Shares, the Shares shall be restricted from sale under a

date of the Registration Statement and January 15, 1997 if the Company's
publicly traded Common Stock trades at an average closing "bid" price of at
least $3.00 per share for a period of ten consecutive trading days.

     After the release of the initial one-third of the Shares, if the Company
has become effective under any subsequent registration statement filed with the
SEC by January 15, 1997 for the purpose of additional raising capital, including
but not limited to any capital formation or value conferred having an immediate
cash benefit or value to the Company in excess of $5,000,000 including private
or public financing, joint venture or licensing, the remaining two-thirds (2/3)
of the Shares shall be locked-up for six months from the date of such subsequent
registration statement, but in no event later than July 15, 1997. If there is
not a subsequent registration statement by January 15, 1997, the Shares will be
released from the lock-up on January 15, 1997. Upon the release of any Shares
after the expiration of the lock-up periods set forth above, after the release
of the initial one-third (1/3) of the Shares, the investor will be permitted to
release the remaining shares at no greater rate than the formula permitted under
the liquidation provisions of SEC Rule 144, as amended.

     2. Agreement to Sell and Purchase Shares. On the basis of the

          (a)  The Purchaser has received a copy of the Disclosure Documents and
               the Purchaser has carefully reviewed the Disclosure Documents and
               this Agreement.

          (b)  The Purchaser has the full right, power and authority to enter
               into this Agreement and to carry out and consummate the
               transactions contemplated herein. This Agreement constitutes the
               legal, valid and binding obligation of the Purchaser enforceable
               in accordance with its terms.

          (c)  The Purchaser is acquiring the Shares for its own account and
               risk and not as part of any plan or scheme to evade the
               registration requirements of the Act, and no other person has any
               interest in or participation in the Shares or any right, option,
               security interest, pledge or other interest in or to the Shares.
               The Purchaser has no plan to redistribute or resell the Shares.
               The Purchaser understands and agrees that it must bear the
               economic risk of its investment in the Shares for an indefinite
               period of time. The Shares of Common Stock have not been
               registered under the Act. The Shares may not be offered or sold,
               directly or indirectly, in the United States unless registered or
               exempt from registration under the Act and any applicable state
               securities or blue sky laws (the "State Acts").

          (d)  The Purchaser agrees to dispose of or encumber its Shares only if
               (i) the Shares are duly registered under the Act and all
               applicable State Acts, or (ii) an exemption from registration
               under the Act, including any exemption from the registration
               requirements of the Act pursuant to Regulation D, and all


                                      4


               applicable State Acts, is available.

          (e)  If the Purchaser is a corporation or trust or other entity, the
               officer or trustee or other person executing this Agreement
               represents and warrants that he is authorized to so sign; that
               the entity is authorized by the governing documents of the entity
               as the case may be, to make this investment;

          (f)  The Purchaser understands that the offer and sale of the Shares
               is being made only by means of this Agreement and the Disclosure
               Documents. In deciding to subscribe for the Shares, the Purchaser
               has not considered any information other than that contained in
               this Agreement and the Disclosure Documents and any documents
               provided to the Purchaser by the Company upon request. The
               Purchaser acknowledges that each of such documents contain on the
               cover thereof a legend as to the absence of registration of the
               Shares under the Act and the restrictions arising under the Act.
               The Purchaser is aware that the purchase of the Shares involves a
               high degree of risk and that the Purchaser may sustain, and has
               the financial ability to sustain, the loss of its entire
               investment.

          (g)  The Purchaser (i) has adequate means of providing for his current
               needs and possible personal contingencies, and has no need for
               liquidity of his investment in the Company, and (ii) is an
               "Accredited Investor" as defined in Rule 501 under Regulation D

               deductions for long-term capital gain or depletion, any
               tax-exempt interest, and allocable losses of any partnership of
               which he is a partner) in excess of $200,000 or a combined income
               with his spouse in excess of $300,000; (iii) a domestic bank, or
