         purpose of obtaining information and has attended or been given
         reasonable opportunity to attend a meeting with representatives of the
         Company for the purpose of asking questions of, and receiving answers
         from, such representatives concerning the terms and conditions of the

         information provided in the Memorandum.

                           City: _________________________
                           State: _________________________

                  3.1.7 Bell's Social Security or Tax Identification No. is:
         ___________

                  3.1.8 The Shares are being purchased by Bell in Bell's name
         solely for Bell's own beneficial interest and not as nominee for, on
         behalf of, for the beneficial interest transfer to, any other person,
         trust, or organization.

                  3.1.9 Bell acknowledges that an investment in the Company is a
         speculative investment involving a high degree of risk including, but
         not limited to the reasons described in the Memorandum and is suitable
         only for persons who can afford to lose their entire investment.

                  3.1.10 Bell realizes that Bell will experience substantial
         dilution in the per share value of the Shares purchased by Bell
         immediately upon purchase.


<PAGE>


                  3.1.11 Bell has, either alone or with the assistance of its
         professional advisor, sufficient knowledge and experience in financial
         and business matters that Bell believes Bell is capable of evaluating
         the merits and risks of the prospective investment in the Shares.

                  3.1.12 Bell has obtained, to the extent Bell deems necessary,
         professional advice with respect to the risks inherent in an investment
         in the Shares, the suitability of the investment in light of Bell's
         financial condition and investment needs, and legal, tax and accounting
         matters.

                  3.1.13 Bell has been given the opportunity to discuss all
         material aspects of this transaction with representatives of The
         Company and any questions asked have been answered to Bell's full
         satisfaction.

                  3.1.14 Bell recognizes that the purchase of the Shares is a
         long-term investment, that, absent registration, transferability and
         sale of the Shares are restricted in many ways, and that Bell could
         sustain a total loss of Bell's investment.

                  3.1.15 Bell can bear the economic risk of an investment in the
         Shares for an indefinite period of time, can afford to sustain a
         complete loss of such investment, has no need for liquidity in
         connection with an investment in the Shares, and can afford to hold the
         Shares indefinitely.

                  3.1.16 Bell o has/o has not (check one) used the services of a
         purchaser representative in connection with this investment. If I have
         used a purchaser representative Bell has received a fully completed and
         executed Purchaser Representative Questionnaire.

                  3.1.17 It is Bell's intention to acquire and hold the Common
         Stock for Bell's own account for investment purposes and not with a
         view to resale in connection with any distribution thereof.

                  3.1.18 Bell has no contract, undertaking, agreement or
         arrangement with any person or company to sell the Shares to any such
         person or company or to have any such person or company sell the Shares
         on Bell's behalf.

                  3.1.19 Bell is not aware of any occurrence, event, or
         circumstance upon the happening of which Bell intends to sell the
         Shares, and Bell does not have any present intention to sell the Shares
         after a lapse of any particular period of time.

                  3.1.20 Bell has been informed that in the view of the United
         States Securities and Exchange Commission ("SEC") and state securities
         commissions, a purchase now with an intent to resell, by reason of any
         foreseeable specific contingency or anticipated change in market
         values, or any change in the condition of the Company, or that of the
         industry, or in connection with a contemplated liquidation or
         settlement of any loan obtained for the acquisition of the Shares,
         would represent a purchase with an intent inconsistent with the
         representations set forth above, and that the SEC, and state securities

<PAGE>

         commissions might regard such resale as a deferred sale with regard to
         which an exemption from registration is not available.

                  3.1.21 Bell is experienced and knowledgeable in financial and
         business matters, capable of evaluating the merits and risks of
         investing in the Shares, and does not need or desire the assistance of
         a knowledgeable representative to aid in the evaluation of such risks
         (or, in the alternative, has a knowledgeable representative who such
         investor intends to use in connection with a decision as to whether to
         purchase the Shares and who together with such investor has such
         knowledge and experience in financial and business matters that they
         are together capable of evaluating the merits and risks of investing in
         the Shares).

                  3.1.22 Bell believes that the investment in the Shares is
         suitable for Bell based upon Bell's investment objectives and financial
         needs, and Bell has adequate means to provide for Bell's current
         financial needs and personal/business contingencies and has no need for
         liquidity of investment with respect to the Shares.

         3.2 Accredited Investor Status.

                  3.2.1 Bell acknowledges that the Company is offering the Units
         only to Accredited Investors as defined in Rule 501(a) of Regulation D
         under the Securities Act of 1933, as amended (the "Act").

                  property and real estate, including your principal residence,
                  cash, short-term investments, stock and securities. Equity in
                  personal property and real estate should be based on the fair
                  market value of such property minus debt secured by such

                  entity all of whose equity owners meet one of the tests set
                  forth above (if relying on this category alone, each equity
                  owner must complete a separate copy of this Agreement).

                           3.2.2.14 Other._______________________________

         3.3 Restricted Nature of Securities Acquired.

                  3.3.1 Bell understands that the Shares to be issued have not
         been registered under the Act, or under applicable state securities
         acts, on the grounds that the Shares are being issued in a transaction
         involving a limited group of knowledgeable investors fully familiar
         with the affairs and proposed operations of the Company and not
         involving a public offering and that, consequently, such transaction is
         exempt from registration under the Act and the state securities acts.

                  3.3.2 In that regard, Bell understands that the Shares may not
         be sold, transferred or otherwise disposed of except pursuant to an
         effective registration statement or appropriate exemption from
         registration under the foregoing securities acts and, as a result,
         absent registration, it may be required to hold the Shares for an
         indefinite period of time.

                  3.3.3 Bell understands that the Company has not agreed to
         register the Shares for distribution in accordance with the provisions
         of the Act or state law, and has not agreed to comply with any
         exemption under the Act or state law for the resale of the Shares. Bell
         understands that by virtue of the rules respecting "restricted
         securities" the Shares must be held indefinitely, unless and until
         subsequently registered under the Act and/or state law or unless an
         exemption from such registration is available.

                  3.3.4 Bell acknowledges that the Company will rely on its
         representations herein as a basis for the exemption from registration.
         Accordingly, it acknowledges that the Company is not required to
         recognize any transfer of the Shares acquired by it if, in the opinion
         of counsel for the Company, such transfer would result in violation of
         any federal or state law regarding the offering or sale of securities.

                  3.3.5 Bell agrees to indemnify, the Company for and from any
         claim, liability, cost or expense, including reasonable attorneys'
         fees, arising from any unlawful sale by Bell or offer by Bell to sell
         or transfer any of the shares subscribed for hereby.

                  3.3.6 Bell acknowledges that Bell may be deemed an "affiliate"
         of the Company within the meaning of Rule 144 ("Rule 144") promulgated
         under the Act, although nothing contained herein should be construed as
         an admission of such fact.

                  3.3.7 If in fact Bell were an affiliate under Rule 144, Bell's
         ability to sell, assign or transfer the Shares may be restricted unless
         such transaction is registered under the Act or an exemption from such
         registration is available.


<PAGE>


                  3.3.8 Bell understands that such exemptions are limited and
         Bell has obtained advice of counsel as to the nature and conditions of
         such exemptions, including information with respect to the
         applicability to the sale of such securities of Rule 144.

                  3.3.9 Bell further represents to and covenants with the
         Company that Bell will not sell, assign or transfer any of the Shares
         except (i) pursuant to an effective registration statement under the
         Act, (ii) pursuant to Rule 144, or (iii) in a transaction which, in the
         opinion of independent counsel reasonably satisfactory to The Company
         or as described in a "no-action" or interpretive letter from the Staff
         of the SEC, is not required to be registered under the Act.

         3.4 Legend on Certificates to be Issued. Bell understands and
acknowledges that the stock certificate representing the Shares to be issued
pursuant to this Agreement will contain substantially the following legend and
such other legends as may be required by the :

                  "The Common Stock represented by this Certificate has not been
         registered under the Securities Act of 1933, as amended, or any state
         Blue Sky law. Such Common Stock has been acquired by the registered
         holder hereof for his or her own account for investment purposes and
         may not be sold, transferred or otherwise disposed of for value, except
         pursuant to registration under all applicable securities laws or the
         receipt by The Company of an opinion of counsel, satisfactory in form
         and substance to The Company, that registration is not required under
         such securities laws.

         3.5 Investment Decision. Bell has carefully read this letter agreement
and has discussed its requirements and other applicable limitations upon Bell's
abilities to offer to sell, transfer or otherwise dispose of Shares, to the
extent Bell felt necessary, with Bell's counsel or counsel for Company. Bell
further acknowledges that Bell has determined that an investment in the Shares
is appropriate for Bell, in view of Bell's overall financial condition.
