                             SUBSCRIPTION AGREEMENT
                            Rule 504 Equity Offering

Gentlemen:

      The undersigned, having received and read a copy of the Offering
Memorandum dated September 1, 2000, concerning an offering of an aggregate of
1,000,000 shares of Common Stock of Aqua Dyne, Inc. (the "Company") hereby makes
an irrevocable offer to purchase money order in the amount of
$______________Shares. Tendered herewith is my check or representing the total
number of Shares subscribed to, at the purchase price of $1.00 per share, made
payable to the order of AQUA DYNE, INC.

         Also enclosed is a fully executed copy of this Subscription Agreement,
in connection with which I hereby represent and agree as follows:

         1.       The funds tendered herewith are irrevocable. Should my
                  subscription be rejected by the Company, the Company shall
                  promptly and fully return the subscription price tendered,
                  without interest or deduction and this Subscription Agreement
                  shall be rendered null and void, and of no further force or
                  affect.

         2.       This subscription is made subject to the following terms and
                  conditions:
                  (a)      The Company has the right to reject this subscription
                           in whole or in part;
                  (b)      No obligation exists on the part of the Company to
                           accept subscriptions in any particular order;
                  (c)      The certificates evidencing the Shares subscribed to
                           herein shall be issued only in my name and delivered
                           only to me;
                  (d)      There is no minimum amount of subscriptions to be
                           received by the Company; and there is no escrow of
                           funds received b the Company.
                  (e)      The offering will terminate on November 29, 2000
                           subject to an extension; or at any time by the
                           Company, prior to the final acceptance of the
                           subscription.

         3.       (a) In making my decision to subscribe to Shares of the
                  Company, I have relied solely upon the information and
                  statements furnished by of the Company in the Offering
                  Memorandum.

         4.       I understand that the Shares are being offered and sold under
                  an exemption from the registration requirements provided by
                  the Securities Act of 1933 (the "1933 Act,") and rules and
                  regulations promulgated thereunder, and certain exemptions
                  from registration provided by state securities laws.

<PAGE>

         5.       This transaction has not been reviewed by, passed on or
                  submitted to the United States Securities and Exchange
                  Commission or to any state agency; accordingly, I make the
                  following additional representations and warranties.

                  (a)      I am a bona fide resident or domiciliary of the State
                           set opposite my name on the signature page, in the
                           sense of being a person resident within such state,
                           having my principal resident and domicile in such
                           state: and I am a United States citizen of at least
                           twenty-one years of age.

                  (b)      I understand and have fully considered, for purposes
                           of this investment, all the provisions of the
                           Offering Memorandum, with special consideration given
                           to the following portions, "Caveats", "Risk Factors,"
                           and "Description of Securities."

                  (c)      I understand the Company has limited operating
                           history and little or no profits and the Units are
                           speculative investments which involve a high degree
                           of risk of loss by the subscriber; therefore, this@
                           investment is more suitable for one who is
                           sufficiently wealthy to afford a loss of his entire
                           investment.

                  (d)      understand that there may be substantial restrictions
                           on the transferability of the Shares (and the
                           certificates will so Indicate), for which there may
                           be no market, and, accordingly, it will probably not
                           be possible to liquidate my investment in the Shares
                           in the case of an emergency need for liquidity.

                  (e)      The Company is relying on the truth and accuracy of
                           my representations, declarations and warranties made
                           herein In their offering the Shares for sale to me
                           and relying upon applicable federal and state
                           exceptions.

                  (f)      The Shares subscribed to herein are being acquired
                           for my account, for investment only, and are not
                           being purchased with a view toward resale,
                           distribution, subdivision or fractionalization. I
                           have no contract, understanding, undertaking,
                           agreement or arrangement, formal or informal, with
                           any person or persons to sell, transfer or pledge the
                           Shares, and I have no present plan to enter Into any
                           such contract or agreement.

                  (g)      I could suffer serious consequences if the
                           statements, representations or warranties made herein
                           to the Company are not true, which could result in my
                           being subjected to the Indemnification provisions set
                           forth below in paragraph 7 hereof.

         6.       I make the within representations, warranties and undertakings
                  with the intent that they may be relied upon in determining my
                  suitability to purchase the Shares, and such representations
                  and warranties shall survive the within subscription.

<PAGE>

         7.       I agree to indemnify and save harmless the Company, its
                  affiliates, officers, directors, legal counsel, accountants
                  and affiliates of any thereof, from any and all claims,
                  liabilities, damages, expenses, losses or actions directly or
                  indirectly arising out of or in connection with the
                  representations, warranties, and agreements contained herein.

         8.       I am not entitled to transfer or assign this Subscription
                  Agreement, or any interest herein, and the issuance of Units
                  pursuant hereto shall be made only in accordance with all
                  applicable laws.

         9.       I am not entitled to cancel, terminate or revoke this
                  Subscription Agreement or any agreements contained herein, and
                  the provisions of this's Subscription Agreement shall survive
                  (i) purchase and issuance of the Units subscribed to herein,
                  and (ii) my death or disability. However, if the Company
                  rejects this Subscription, this Subscription Agreement shall
                  automatically be canceled, terminated and revoked.

         10       (a) If executing this Subscription Agreement in a
                  representative or fiduciary capacity, I have full power and
                  authority to execute and deliver this Subscription Agreement
                  in such capacity and on behalf of the subscribing individual,
