Securities Act, including without limitation Regulation D under the Securities
Act and Section 4(2) of the Securities Act, provided, however, that except as

                  4.9      SEC DOCUMENTS. As of their respective dates, the SEC
Documents complied, and all similar documents filed with the SEC prior to each
Closing Date will comply, in all material respects with the requirements of the
Securities Act or the Exchange Act, as the case may be, and the rules and
regulations of the SEC promulgated thereunder and other federal, state and local
laws, rules and regulations applicable to such SEC Documents, and none of the
SEC Documents contained, nor will any similar document filed with the SEC prior
to each Closing Date contain, any untrue statement of a material fact or omitted
or omit to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. The financial statements of the Company included
in the SEC Documents, as of the dates thereof, complied, and all similar
documents filed with the SEC prior to each Closing Date will comply, as to form
in all material respects with applicable accounting requirements and the
published rules and regulations of the SEC and other applicable rules and
regulations with respect thereto. Such financial statements were prepared in
accordance with generally accepted accounting principles applied on a consistent
basis during the periods involved (except (i) as may be otherwise indicated in
such financial statements or the notes thereto or (ii) in the case of unaudited
interim statements, to the extent they may not include footnotes or may be
condensed or summary statements as permitted by Form 10-QSB of the SEC) and
fairly present in all material respects the financial position of the Company
and its consolidated Subsidiaries as of the dates thereof and the consolidated
results of operations and cash flows for the periods then ended (subject, in the
case of unaudited statements, to normal year-end audit adjustments).

                  4.10     NO UNDISCLOSED LIABILITIES. Except to the extent
described in Schedule 4.10, the Company and the Subsidiaries have no liabilities
or obligations of a financial nature (whether accrued, absolute, contingent or
otherwise), which are material, individually or in the aggregate, and are not
disclosed in the SEC Documents, other than those incurred in the ordinary course
of the Company's or the Subsidiaries' respective businesses consistent with past
practice since December 31, 1996, and which, individually or in the aggregate,
do not or would not have a Material Adverse Effect on the Company.

                  4.11     LITIGATION AND OTHER PROCEEDINGS. Except as may be
set forth in the SEC Documents or otherwise disclosed in writing to Purchaser,
there are no lawsuits or proceedings pending or to the knowledge of the Company
threatened, against the Company, nor has the Company received any written or
oral notice of any such action, suit, proceeding or investigation, which might
have a Material Adverse Effect on the Company or which might materially
adversely affect the transactions contemplated by this Agreement. Except as set
forth in the SEC Documents, no judgment, order, writ, injunction or decree or
award has been issued by or, to the knowledge of the Company, requested of any
court, arbitrator or governmental agency which might result in a Material
Adverse Effect or which might materially adversely affect the transactions
contemplated by this Agreement.

                  4.12     OTHER DOCUMENTS OR MATERIALS. With respect to any
document or other materials received by Purchaser from the Company or its
representatives other than the Transaction


                                       10
<PAGE>

Documents and the SEC Documents, (i) the Company has no reason to believe any of
such documents and materials or any projections contained therein, as of the
date of such other documents or materials, contained material errors or
misstatements or do not adequately describe the status of the development of the
Company's technologies or its business as of such date, and (ii) such documents,
materials and projections were prepared by the Company and its management in
good faith.

                  4.13     NATURE OF COMPANY. The Company is not an open ended
investment company or a unit investment trust, registered or required to be
registered, or a closed end investment company required to be registered, but
not registered, under the Investment Company Act of 1940.

                  4.14     BROKERS, FINDERS. Except for payment of commitment
fees to Purchaser, payment of which is the sole responsibility of the Company,
the Company has taken no action which would give rise to any claim by any person
for brokerage commission, finder's fees or similar payments by Purchaser
relating to this Agreement or the transactions contemplated hereby. Purchaser
shall have no obligation with respect to such fees or with respect to any claims
made by or on behalf of other Persons for fees of a type contemplated in this
Section 4.14 that may be due in connection with the transactions contemplated
hereby. Any fees due to Alliance Financial LLC in connection with this
transaction shall be the obligation of First Fidelity Capital.

                  4.15     ABSENCE OF CERTAIN CHANGES. Since January 31, 2000,
no Material Adverse Effect has been suffered by, and no material adverse
development has occurred in the business, properties, operations, financial
condition or results of operations of the Company or the Subsidiaries. The
Company has not taken any steps, and does not currently expect to take any
steps, to seek protection pursuant to any bankruptcy law nor does the Company or
any of the Subsidiaries have any knowledge or reason to believe that its
creditors intend to initiate involuntary bankruptcy proceedings.

                  4.16     INTELLECTUAL PROPERTY RIGHTS. Other than as described
in the SEC Documents, the Company and the Subsidiaries own or possess adequate
rights or licenses to use all trademarks, trade names, service marks, service
mark registrations, service names, patents, patent rights, copyrights,
inventions, licenses, approvals, governmental authorizations, trade secrets and
rights necessary to conduct their respective businesses as now conducted. None
of the Company's trademarks, trade names, service marks, service mark
registrations, service names, patents, patent rights, copyrights, inventions,
licenses, approvals, government authorizations, trade secrets or other
intellectual property rights have expired or terminated, or are expected to
expire or terminate in the near future. Other than as described in the SEC
Documents, the Company and the Subsidiaries do not have any knowledge of any
infringement by the Company or the Subsidiaries of trademarks, trade name
rights, patents, patent rights, copyrights, inventions, licenses, service names,
service marks, service mark registrations, trade secrets or other similar rights
of others, or of any such development of similar or identical trade secrets or
technical information by others and, there is no claim, action or proceeding
being made or brought against, or to the best knowledge of the Company, being
threatened against, the Company or the Subsidiaries regarding trademark, trade
name, patent,


                                       11
<PAGE>

patent rights, invention, copyright, license, service name, service mark,
service mark registration, trade secret or other infringement; and the Company
and the Subsidiaries are unaware of any facts or circumstances which might give
rise to any of the foregoing. The Company and the Subsidiaries have taken
reasonable security measures to protect the secrecy, confidentiality and value
of all of their intellectual properties.

                  4.17     INTERNAL ACCOUNTING CONTROLS. The Company is aware of
no respect in which its system of internal accounting controls is not sufficient
to provide reasonable assurance that (i) transactions are executed in accordance
with management's general or specific authorizations, (ii) transactions are
recorded as necessary to permit preparation of financial statements in
conformity with generally accepted accounting principles and to maintain asset
accountability, (iii) access to assets is permitted only in accordance with
management's general or specific authorization and (iv) the recorded
accountability for assets is compared with the existing assets at reasonable
intervals and appropriate action is taken with respect to any differences.

                  4.18     TAX STATUS. The Company and the Subsidiaries have
made or filed all federal and state income and all other tax returns, reports
and declarations required by any jurisdiction to which it is subject and has
paid all taxes and other governmental assessments and charges that are material
in amount, shown or determined to be due on such returns, reports, declarations,
except those being contested in good faith and has set aside on its books
provisions reasonably adequate for the payment of all taxes for periods
subsequent to the periods to which such returns, reports, or declarations apply.
There are no unpaid taxes in any material amount claimed to be due by the taxing
authority of any jurisdiction, and the officers of the Company know of no basis
for any such claim.

                  4.19     CERTAIN TRANSACTIONS. Except as set forth in
Schedule 4.19 or in the SEC Documents and except for arm's length
transactions pursuant to which the Company makes payments in the ordinary
course of business upon terms no less favorable than the Company could obtain
from third parties and other than the grant of stock options, none of the
officers, directors, or employees of the Company (or any spouse or relative
of any such person) is presently a party to any transaction with the Company
(other than for services as employees, officers, consultants and directors),
including any contract, agreement or other arrangement providing for the
furnishing of services to or by, providing for rental of real or personal
property to or from, or otherwise requiring payments to or from any officer,
director or such employee or, to the knowledge of the Company, any
corporation, partnership, trust or other entity in which any officer,
director, or any such employee has a substantial interest or is an officer,
director, trustee or partner.

                  4.20     DILUTION. The Company's executive officers and
directors have studied and fully understand the nature of the transactions
contemplated by this Agreement and recognize that they have a potential dilutive
effect. The board of directors of the Company has concluded, in its good faith
business judgment, that such issuance is in the best interests of the Company.

                  4.21     OTC BB LISTING. The Company's Common Stock is
presently quoted on the Over the Counter Bulletin Board under the symbol "AQSE."
The Company is not in receipt of any


                                       12
<PAGE>

written notice from any stock exchange, market or trading facility on which the
Common Stock is or has been listed (or on which it is or has been quoted) to the
effect that the Company is not in compliance with the listing or maintenance
requirements of such stock exchange, market or trading facility or that the
Common Stock will be delisted from such stock exchange, market or trading
facility.

                  4.22     NO INTEGRATED OFFERING. Neither the Company nor any
of its affiliates nor any person acting on its or their behalf has, directly or
indirectly, at any time since December 31, 1999, made any offer or sales of any
security or solicited any offers to buy any security under circumstances that
would eliminate the availability of the exemption from registration under
Regulation D in connection with the offer and sale of the Securities as
contemplated hereby.

         5.       USE AND DISPOSITION OF PROCEEDS. The Company will use the
proceeds from the sale of the Common Stock (excluding amounts paid by the
Company for legal fees and finder's fees in connection with the sale to
Purchaser) but shall not, directly or indirectly, use such proceeds for
investment in any other Affiliate or to repay debt to Affiliates.

         6.       COMPANY RELIANCE ON PURCHASER'S REPRESENTATIONS. Purchaser
understands that the Company is relying on the truth and accuracy of the
representations and warranties made herein by Purchaser in offering the
Securities for sale and in relying upon applicable exemptions available under
the Securities Act and applicable state securities laws.

         7.       RESTRICTED SHARES. Purchaser understands and acknowledges that
if the Securities have not been, and will not as of the time issued be,
registered under the Securities Act, they will be issued in reliance upon
exemptions from the registration requirements of the Securities Act, and thus
cannot be resold unless they are included in an effective registration statement
filed under the Securities Act or unless an exemption from registration is
available for such resale. With regard to the restrictions on resales of the
Securities, Purchaser is aware (a) that the Company will issue stop transfer
orders to its stock transfer agent in the event of attempts to improperly
transfer any Securities; and (b) that a restrictive legend will be placed on
certificates representing the Securities, which legend will read substantially
as follows:

         THESE SECURITIES ARE NOT REGISTERED WITH THE UNITED STATES SECURITIES
         AND EXCHANGE COMMISSION UNDER THE SECURITIES ACT OF 1933, AS AMENDED
         (THE "ACT"), PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE ACT
         AND REGULATIONS PROMULGATED UNDER THE ACT, INCLUDING EXEMPTIONS UNDER
         SECTIONS 3(b) AND 4(2) OF THE ACT AND THE PROVISIONS OF REGULATION D
         UNDER SUCH ACT, AND SIMILAR EXEMPTIONS UNDER STATE LAW. ACCORDINGLY,
         THESE SECURITIES MAY NOT BE RESOLD, TRANSFERRED, PLEDGED, ASSIGNED OR
         HYPOTHECATED UNLESS SUCH SECURITIES ARE COVERED BY AN EFFECTIVE
         REGISTRATION STATEMENT FILED UNDER THE ACT OR AN EXEMPTION FROM SUCH


                                       13
<PAGE>

         REGISTRATION REQUIREMENT IS AVAILABLE AND THE COMPANY HAS
         RECEIVED AN OPINION OF SECURITIES COUNSEL REASONABLY
         SATISFACTORY TO THE COMPANY THAT SUCH EXEMPTION IS
         AVAILABLE.

The legend set forth above shall be promptly removed without additional cost or
delay, and the Company shall issue a certificate without such legend to the
holder of any of the Securities upon which such legend is stamped (or to the
holder's assignee), if, unless otherwise required by state securities laws, (i)
such securities are registered for resale, or have been sold, under an effective
registration statement under the Securities Act, (ii) in connection with a sale
transaction, such holder provides the Company with an opinion of counsel, in a
generally acceptable form, to the effect that a public sale, assignment or
transfer of the Securities may be made without registration under the Securities
Act, or (iii) such holder provides the Company with reasonable assurances that
the Securities can be sold pursuant to Rule 144 promulgated under the Securities
Act without any restriction as to the number of securities acquired as of a
particular date that can then be immediately sold. Notwithstanding the removal
of the legend set forth above, in the event the Securities are registered for
resale on an effective registration statement, the Company reserves the right to
affix a legend on certificates representing the Securities that any selling
shareholder named in the registration statement must comply with the prospectus
delivery requirements of the Securities Act in connection with any resale. The
Company shall bear the cost of the removal of any legend as anticipated by this
Section 7.

         8.       OTHER COVENANTS OF THE COMPANY.

                  8.1      FURNISHING OF INFORMATION. As long as Purchaser owns
Securities, the Company covenants to use all diligent efforts to timely file (or
obtain extensions in respect thereof and file within the applicable grace
period) all reports required to be filed by the Company after the date hereof
pursuant to Section 13(a) or 15(d) of the Exchange Act. If at any time prior to
the date on which Purchaser may resell all of the Securities without volume
restrictions pursuant to Rule 144(k) promulgated under the Securities Act (as
determined by counsel to the Company pursuant to a written opinion letter to
such effect, addressed and acceptable to the Company's transfer agent for the
benefit of and enforceable by Purchaser) the Company is not required to file
reports pursuant to such sections, it will prepare and furnish to Purchaser and
make publicly available in accordance with Rule 144(c) promulgated under the
Securities Act annual and quarterly financial statements, together with a
discussion and analysis of such financial statements in form and substance
substantially similar to those that would otherwise be required to be included
in reports required by Section 13(a) or 15(d) of the Exchange Act in the time
period that such filings would have been required to have been made under the
Exchange Act. The Company further covenants that it will take such further
action as any holder of Securities may reasonably request, all to the extent
required from time to time to enable such Person to sell Securities without
registration under the Securities Act within the limitation of the exemptions
provided by Rule 144 promulgated under the Securities Act.


                                       14

                  8.2      CERTAIN AGREEMENTS. The Company covenants and agrees
that it will not, without the prior written consent of Purchaser enter into any
subsequent or further offer or sale of Common Stock or securities convertible

                           (a)      The provisions of this subparagraph will not
apply to (w) the sale and issuance of up to four million ($4,000,000) dollars of
Common Stock on or before September 4, 2000, (x) Common Stock issued pursuant to
Rule 144, provided the holder thereof holds such Common Stock for at least one
year from the date of issuance; or (y) the issuance of securities (other than
for cash) in connection with a merger, consolidation, sale of assets,
disposition or the exchange of the capital stock for assets, stock or other
joint venture interests; or (z) Upon conversion or exercise of any convertible

transferable divisible warrants (i) upon execution hereof, to purchase one

equal to eighty percent (80%) of the Closing Bid Price of the Common Stock on
the date hereof (the "Initial Warrant"); (ii) upon the effectiveness of the
Registration Statement required to be filed pursuant to Section 2 of the
Registration Rights Agreement, to purchase one million, three hundred fifty
thousand (1,350,000) shares of Common Stock at an exercise price equal to eighty

trading days immediately prior to the date that the Registration Statement is
declared effective by the Securities and Exchange Commission (the "Registration
Warrant"); and (iii) to purchase a maximum of nine hundred and fifty thousand
(950,000) shares of Common Stock ("Additional Warrants") on a pro rata basis in
conjunction with each Additional Closing, exercisable at the closing bid price,
at the date of each Additional Closing.

                  8.4      AVAILABLE SHARES. The Company shall have at all times
authorized and reserved for issuance, free from preemptive rights, a sufficient
number of shares under the terms of this Agreement, and Common Stock for
issuance pursuant to the exercise of the Warrants.

                  8.5      REIMBURSEMENT. If (i) Purchaser, other than by reason
of its gross negligence or willful misconduct, becomes involved in any capacity
in any action, proceeding or investigation brought by any stockholder of the
Company, in connection with or as a result of the consummation of the
transactions contemplated by the Transaction Documents, or if Purchaser is
impleaded in any such action, proceeding or investigation by any Person, or (ii)
Purchaser, other than by reason of its gross negligence or willful misconduct or
by reason of its trading of the Common Stock in a manner that is illegal under
applicable securities laws, becomes involved in any capacity in any action,
proceeding or investigation brought by the SEC against or involving the Company
or in connection with or as a result of the consummation of the transactions
contemplated by the Transaction Documents, or if Purchaser is impleaded in any
such action, proceeding or investigation by any Person, then in any such case,
the Company will reimburse Purchaser for its reasonable legal and other expenses
(including the cost of any investigation and preparation) incurred in connection


                                       15
<PAGE>

therewith, as such expenses are incurred. In addition, other than with respect
to any matter in which Purchaser is a named party, the Company will pay
Purchaser the charges, as reasonably determined by Purchaser, for the time of
any officers or employees of Purchaser devoted to appearing and preparing to
appear as witnesses, assisting in preparation for hearings, trials or pretrial
matters, or otherwise with respect to inquiries, hearing, trials, and other
proceedings relating to the subject matter of this Agreement. The reimbursement
obligations of the Company under this paragraph shall be in addition to any
liability which the Company may otherwise have, shall extend upon the same terms
and conditions to any Affiliates of Purchaser who are actually named in such
action, proceeding or investigation, and partners, directors, agents, employees

Affiliate, and shall be binding upon and inure to the benefit of any successors,
assigns, heirs and personal representatives of the Company, Purchaser and any
such Affiliate and any such Person. The Company also agrees that neither any
Purchaser nor any such Affiliate, partners, directors, agents, employees or
controlling persons shall have any liability to the Company or any person
asserting claims on behalf of or in right of the Company in connection with or
as a result of the consummation of the Transaction Documents except to the
extent that any losses, claims, damages, liabilities or expenses incurred by the
Company result from the gross negligence or willful misconduct of Purchaser or
any inaccuracy in any representation or warranty of Purchaser contained in
herein or any breach by Purchaser of any of the provisions hereof.

         9.       TRANSFER AGENT INSTRUCTIONS.

                  9.1      IRREVOCABLE INSTRUCTIONS. Subject to the provisions

Agreement, the Registration Rights Agreement, and applicable law. Nothing in
this Section 9 shall affect in any way Purchaser's obligations and agreement to

Dundee Securities Corporation
Suite 3424, Four Bentell Centre
1055 Dunsmuir Street, P. O. Box 49207
Vancouver, BC V7X 1KB

RE:           Alpha Venture Capital, Inc.

Dear Sirs:

         As escrow agent for both Aquasearch, Inc., a Colorado corporation (the
"Company"), and Alpha Venture Capital, Inc., a Cook Islands corporation (the
"Purchaser") of Shares of the Company, who is named in the Common Stock Purchase
Agreement (the "Agreement") between the Company and the Purchaser to which a
copy of these Securities Joint Escrow Instructions is attached as Exhibit A (the
"Agreement") (capitalized terms used herein and not otherwise defined herein
shall have the respective meanings provided in the Agreement), you (hereafter,
the "Share Escrow Agent") are hereby authorized and directed to hold the
documents delivered to the Share Escrow Agent pursuant to the terms of the
Agreement in accordance with the following instructions:

         1. Upon its acceptance of the Common Stock Purchase Agreement, the
Company shall deliver or cause to be delivered to the Share Escrow Agent, common
stock share certificates evidencing a total of twenty million (20,000,000)
shares consisting of twenty (20) certificates of one million (1,000,000) shares
each (collectively the "Share Certificates").

         2. The Share Certificates delivered to the Share Escrow Agent pursuant
hereto shall be deposited for safekeeping with the Share Escrow Agent (the
"Escrow Account"). During the Escrow Period (hereinafter defined), none of the
Share Certificates deposited in the Escrow Account shall become the property of
the Purchaser or any other entity or be subject to the debts of the Purchaser or
any other entity except as expressly provided herein, and the Share Escrow Agent
shall neither make nor permit any disbursements or deliveries from the Escrow
Account except as expressly provided herein.

         3. The Escrow Period shall begin on the effective date of the Agreement
and, except as provided in Section 4 below, shall continue until it expires
pursuant to Section 2.2(g) of the Agreement. Notwithstanding the foregoing, if
there remain Share Certificates in the Escrow Account, all such Share
Certificates then remaining in the Escrow Account shall forthwith be

<PAGE>

forwarded to American Securities Transfer & Trust, Inc., the transfer agent for
the Company's Common Stock (the "Transfer Agent"), within five (5) business
thereafter upon written request given to Share Escrow Agent by the Company.

         4. Not later than two (2) business days after the Share Valuation Date,
the Company shall deliver a letter to the Share Escrow Agent advising the Share
Escrow Agent of the maximum number of shares that may be sold by the Purchaser
free of restrictive legend pursuant to the relevant Put Notice. The Share Escrow
Agent shall promptly, upon receipt of such letter, deliver one or more Share
Certificates to the Transfer Agent for removal of legend pursuant to the
instructions annexed hereto. Purchaser shall make payment of the Put Amount
(less any applicable legal or other fees) within three (3) business days of such
untendered share certificates to the Share Escrow Agent (the "Share Payment
Date").

         5. Upon receipt of such Share Certificates, the Share Escrow Agent
shall cause same to be delivered to or for the benefit of the Purchaser pursuant
to written instructions of the Purchaser.

         6. The Company shall deliver to the Share Escrow Agent appropriate
written notice of any extension or amendment to the Agreement.

         7. The Share Escrow Agent's duties hereunder may be altered, amended,
modified or revoked only by a writing signed by the Company, the Purchaser and
the Share Escrow Agent.

         8. The Share Escrow Agent shall be obligated only for the performance
of such duties as are specifically set forth herein and may rely and shall be
protected in relying or refraining from acting on any instrument reasonably
believed by the Share Escrow Agent to be genuine and to have been signed or
presented by the proper party or parties. The Share Escrow Agent shall not be
personally liable for any act the Share Escrow Agent may do or omit to do
hereunder as Share Escrow Agent while acting in good faith, and any act done or
omitted by the Share Escrow Agent pursuant to the advice of the Share Escrow
Agent's attorneys-at-law shall be conclusive evidence of such good faith.

         9. The Share Escrow Agent is hereby expressly authorized to disregard
any and all warnings given by any of the parties hereto or by any other person
or corporation, excepting only orders or process of courts of law and is hereby
expressly authorized to comply with and obey orders, judgments or decrees of any
court. In case the Share Escrow Agent obeys or complies with any such order,
judgment or decree, the Share Escrow Agent shall not be liable to any of the
parties hereto or to any other person, firm or corporation by reason of such
decree being subsequently reversed, modified, annulled, set aside, vacated or
found to have been entered without jurisdiction.

         10. The Share Escrow Agent shall not be liable in any respect on
account of the identity, authorities or rights of the parties executing or
delivering or purporting to execute or deliver the Agreement or any documents or
papers deposited or called for hereunder.


                                        2

         11. The Share Escrow Agent shall be entitled, at its own expense, to
employ such legal counsel and other experts as the Share Escrow Agent may deem
necessary properly to advise the Share Escrow Agent in connection with the Share
Escrow Agent's duties hereunder, may rely upon the advice of such counsel, and
may pay such counsel reasonable compensation therefor.

         12. The Share Escrow Agent's responsibilities as Share Escrow Agent
hereunder shall terminate if the Share Escrow Agent shall resign by written
notice to the Company and the Purchaser. In the event of any such resignation,
the Purchaser and the Company shall appoint a successor Share Escrow Agent that
is agreeable to both parties.

         13. If the Share Escrow Agent reasonably requires other or further
instruments in connection with these Securities Joint Escrow Instructions or
obligations in respect hereto, the necessary parties hereto shall join in
furnishing such instruments.

         14. It is understood and agreed that should any dispute arise with
respect to the delivery and/or ownership or right of possession of the documents
held by the Share Escrow Agent hereunder, the Share Escrow Agent is authorized
and directed in the Share Escrow Agent's sole discretion (a) to retain in the
Share Escrow Agent's possession without liability to anyone all or any part of
said documents or Escrow Funds until such disputes shall have been settled
either by mutual written agreement of the parties concerned or by a final order,
decree or judgment of a court of competent jurisdiction after the time for
appeal has expired and no appeal has been perfected, but the Share Escrow Agent
shall be under no duty whatsoever to institute or defend any such proceedings or
(b) to deliver the Escrow Funds and any other property and documents held by the
Share Escrow Agent hereunder to a state or federal court having competent
subject matter jurisdiction and located in the City of Los Angeles and State of
California in accordance with the applicable procedure therefor.

         15. The Company and the Purchaser agree jointly and severally to
indemnify and hold harmless the Share Escrow Agent and its officers, employees
and agents from any and all claims, liabilities, costs or expenses in any way
arising from or relating to the duties or performance of the Share Escrow Agent
hereunder other than any such claim, liability, cost or expense to the extent
the same shall have been determined by final, unappealable judgment of a court
of competent jurisdiction to have resulted from the gross negligence or willful
misconduct of the Share Escrow Agent. It is understood and agreed that this
indemnification shall survive the termination or discharge of this agreement or
the resignation of the Share Escrow Agent.

         16. Any notice required or permitted hereunder shall be given in
writing (unless otherwise specified herein) and shall be deemed effectively
given upon personal delivery or five (5) business days after deposit in the

Gentlemen:

         As escrow agent for both Aquasearch, Inc., a Colorado corporation (the
"Company"), and Alpha Venture Capital, Inc., a Cook Islands corporation (the
"Buyer") of Common Stock (the "Common Stock") of the Company, who is named in
the Common Stock Purchase Agreement between the Company and the Buyer to which a
copy of these Joint Escrow Instructions is attached as Exhibit B (the
"Agreement"; capitalized terms used herein and not otherwise defined herein
shall have the respective meanings provided in the Agreement), you (hereafter,
the "Escrow Agent") are hereby authorized and directed to hold the documents and
funds (together with any interest thereon, the "Escrow Funds") delivered to the
Escrow Agent pursuant to the terms of the Agreement in accordance with the
following instructions:

          1. The Escrow Agent shall, as promptly as feasible, notify the
Company of receipt of the Put Amount for the relevant Common Stock from or on
behalf of the Buyer, and notify the Buyer (or such agent as the Buyer may
designate in writing) of receipt of the relevant Common Stock. As promptly as
feasible upon receipt of written notice from the Company and the Buyer that the
respective conditions precedent to the purchase and sale have been satisfied
(which notice shall not be unreasonably withheld), the Escrow Agent shall, after
reduction by the amounts referred to in the next succeeding sentences of this
paragraph, release the relevant Escrow Funds to or upon the order of the
Company, and shall release the relevant Common Stock to the Buyer. After receipt
of such notice, the amount of five percent (5%) of the Put Amount of the
relevant Common Stock as the aggregate commitment fee to the Buyer shall be
released up to an amount of $5,000,000.00, thereafter the amount of three
percent (3%) of the Put Amount of the relevant Common Stock as the aggregate
commitment fee to the Buyer shall be released If the Company and the Buyer
notifies the Escrow Agent that on the relevant Closing Date the conditions
precedent to the obligations of the Company or the Buyer, as the case may be,
under the Agreement to be effected that date were not satisfied or waived, then
the Escrow Agent shall return the relevant Escrow Funds to the Buyer. Prior to
return of any Escrow Funds to the Buyer, the Buyer shall furnish such tax
reporting or other information as shall be appropriate for the Escrow Agent to
comply with applicable United States

<PAGE>

         laws. The Escrow Agent shall deposit all funds received hereunder in
the Escrow Agent's account at Manufacturer's Trust.

          2. The Escrow Agent's duties hereunder may be altered, amended,
modified or revoked only by a writing signed by the Company, the Buyer and the
Escrow Agent.

          3. The Escrow Agent shall be obligated only for the performance of
such duties as are specifically set forth herein and may rely and shall be
protected in relying or refraining from acting on any instrument reasonably
believed by the Escrow Agent to be genuine and to have been signed or presented
by the proper party or parties. The Escrow Agent shall not be personally liable
for any act the Escrow Agent may do or omit to do hereunder as the Escrow Agent
while acting in good faith, and any act done or omitted by the Escrow Agent
pursuant to the advice of the Escrow Agent's attorneys-at-law shall be
conclusive evidence of such good faith.

          4. The Escrow Agent is hereby expressly authorized to disregard any
and all warnings given by any of the parties hereto or by any other person or
corporation, excepting only orders or process of courts of law and is hereby
expressly authorized to comply with and obey orders, judgments or decrees of any
court. In case the Escrow Agent obeys or complies with any such order, judgment
or decree, the Escrow Agent shall not be liable to any of the parties hereto or
to any other person, firm or corporation by reason of such decree being
subsequently reversed, modified, annulled, set aside, vacated or found to have
been entered without jurisdiction.

          5. The Escrow Agent shall not be liable in any respect on account of
the identity, authorities or rights of the parties executing or delivering or
purporting to execute or deliver the Agreement or any documents or papers
deposited or called for hereunder.

          6. The Escrow Agent shall be entitled to employ such legal counsel
and other experts as the Escrow Agent may deem necessary to advise the Escrow
Agent in connection with the Escrow Agent's duties hereunder, may rely upon the
advice of such counsel, and may pay such counsel reasonable compensation
therefor.

          7. The Escrow Agent's responsibilities as escrow agent hereunder
shall terminate if the Escrow Agent shall resign by written notice to the
Company and the Buyer. In the event of any such resignation, the Buyer and the
Company shall appoint a mutually agreeable successor Escrow Agent.

          8. If the Escrow Agent reasonably requires other or further
instruments in connection with these Joint Escrow Instructions or obligations in
respect hereto, the necessary parties hereto shall join in furnishing such
instruments.

          9. It is understood and agreed that should any dispute arise with
respect to the delivery and/or ownership or right of possession of the documents
or the Escrow Funds held by the Escrow Agent hereunder, the Escrow Agent is
authorized and directed in the Escrow Agent's sole discretion (a) to retain in
the Escrow Agent's possession without liability to anyone all or any part of
said


                                        2
<PAGE>

         documents or the Escrow Funds until such disputes shall have been
settled either by mutual written agreement of the parties concerned or by a
final order, decree or judgment of a court of competent jurisdiction after the
time for appeal has expired and no appeal has been perfected, but the Escrow
Agent shall be under no duty whatsoever to institute or defend any such
proceedings or (b) to deliver the Escrow Funds and any other property and
documents held by the Escrow Agent hereunder to a state or federal court having
competent subject matter jurisdiction and located in the City of Los Angeles and
State of California in accordance with the applicable procedure therefor.

         10. The Company and the Buyer agree jointly and severally to indemnify
and hold harmless the Escrow Agent from any and all claims, liabilities, costs
or expenses in any way arising from or relating to the duties or performance of
the Escrow Agent hereunder other than any such claim, liability, cost or expense
to the extent the same shall (a) have been tax obligations in connection with
Escrow Agent's fee hereunder, or (b) have been determined by final, unappealable
judgment of a court of competent jurisdiction to have resulted from the gross
negligence or willful misconduct of the Escrow Agent, or (c) be a liability, or
arise from liability, to either the Company or the Buyer.

         11. Any notice required or permitted hereunder shall be given in manner
provided in the Section headed "NOTICES" in the Agreement, the terms of which
are incorporated herein by reference.

         12. By signing these Joint Escrow Instructions, the Escrow Agent
becomes a party hereto only for the purpose of these Joint Escrow Instructions;
the Escrow Agent does not become a party to the Agreement. The Company and the
Buyer have become parties hereto by their execution and delivery of the
Agreement, as provided therein.

         13. This instrument shall be binding upon and inure to the benefit of
the parties hereto, and their respective successors and permitted assigns and
shall be governed by the laws of the State of California without giving effect
to principles governing the conflicts of laws. A facsimile transmission of these
instructions signed by the Escrow Agent shall be legal and binding on all
parties hereto.

without the written consent of the other parties hereto. These Joint Escrow
Instructions constitute the entire agreement amongst the parties with respect to
the subject matter hereof.

                        TRANSFER AGENT INSTRUCTIONS


                                                          ________________, 2000


Ladies & Gentlemen:

         Reference is made to that certain Common Stock Purchase Agreement (the
"Agreement") between AQUASEARCH, INC., a Colorado corporation (the "Company"),
and ALPHA VENTURE CAPITAL, INC., a Cook Islands corporation (the "Investor")
pursuant to which the Company is issuing to the Investor shares (the "Shares")
of the Company's common stock, $.0001 par value per share (the "Common Stock")
and certain Common Stock purchase warrants (the "Warrants") which shall be
exercisable into shares of Common Stock. The shares of Common Stock issuable
upon exercise of the Warrants are referred to herein as "Warrant Shares"). The
Shares and Warrant Shares are collectively referred to herein as "Underlying
Shares".

         This letter shall serve as our irrevocable authorization and direction
to you (provided that you are the transfer agent for the Company with respect to
its Common Stock at such time) to issue Underlying Shares from time to time upon
notice from the Company to issue such Underlying Shares. So long as you have
previously received (x) an opinion of the Company's outside counsel
substantially in the form of Exhibit I attached hereto (which the Company shall
direct be delivered to you by such outside counsel upon the effectiveness of the
registration statement covering resales of Underlying Shares) stating that a
registration statement covering resales of Underlying Shares has been declared
effective by the Securities and Exchange Commission under the Securities Act of
1933, as amended, and that Underlying Shares may be issued (or reissued if they
have been issued at a time when there was not such an effective registration
statement) or resold without any restrictive legend (the "Opinion"), (y) a copy
of such registration statement and (z) an appropriate representation that the
resale prospectus contained in the registration statement will be delivered in
compliance with applicable rules and regulations, then certificates representing
Underlying Shares shall not bear any legend restricting transfer of Underlying
Shares thereby and should not be subject to any stop-transfer restriction.
Provided, however, that if you have not previously received a copy of the
Opinion, such registration statement and such representation, then certificates
representing Underlying Shares shall bear the following legend:

                  THESE SECURITIES HAVE NOT BEEN REGISTERED WITH
                  THE SECURITIES AND EXCHANGE COMMISSION OR THE
                  SECURITIES COMMISSION OF ANY STATE IN RELIANCE
                  UPON AN EXEMPTION FROM REGISTRATION UNDER THE

<PAGE>

                  SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),
                  AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT
                  TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES
                  ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A
                  TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF
                  THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE
                  SECURITIES LAWS.

and, provided, further, that the Company may, from time to time, notify you to
place stop-transfer restrictions on the certificates for Underlying Shares in
the event, but only in the event, a registration statement covering Underlying
Shares is subject to amendment for events then current.

         Please be advised that the Investor has relied upon this instruction
letter as an inducement to enter into the Purchase Agreement and, accordingly,
the Investor, is a third party beneficiary to these instructions.

         Please execute this letter in the space indicated to acknowledge your
agreement to act in accordance with these instructions. Should you have any
questions concerning this matter, please contact me at ______________________.

                                   Very truly yours,

THESE SECURITIES AND THE SECURITIES ISSUABLE UPON THEIR EXERCISE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE TRANSFERRED UNLESS
COVERED BY AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID ACT, A "NO ACTION"
LETTER FROM THE SECURITIES AND EXCHANGE COMMISSION WITH RESPECT TO SUCH
TRANSFER, A TRANSFER MEETING THE REQUIREMENTS OF RULE 144 OF THE SECURITIES AND
EXCHANGE COMMISSION, OR AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER TO THE
EFFECT THAT ANY SUCH TRANSFER IS EXEMPT FROM SUCH REGISTRATION.

                                AQUASEARCH, INC.

                          COMMON STOCK PURCHASE WARRANT

                  1.       ISSUANCE. In consideration of good and valuable
consideration, the receipt of which is hereby acknowledged by AQUASEARCH, INC.,
a Colorado corporation (the "Company"), ALPHA VENTURE CAPITAL, INC., or
registered assigns (the "Holder") is hereby granted the right to purchase at any
time commencing ____________________ until 5:00 P.M., New York City time, on
_____________ (the "Expiration Date"), _____________________________
(______________)1 fully paid and nonassessable shares of the Company's Common
Stock, par value $.0001 per share (the "Common Stock") at an initial exercise
price of $_______ per share (the "Exercise Price"), subject to further
adjustment as set forth in Section 6 hereof.

                  2.       EXERCISE OF WARRANTS. (a) This Warrant is exercisable
in whole or in part at the Exercise Price per share of Common Stock payable
hereunder, payable in cash or by certified or official bank check, or by
"cashless exercise", by means of tendering this Warrant to the Company to
receive a number of shares of Common Stock equal to the difference between the
Market Value of the shares of Common Stock issuable upon exercise of this
Warrant and the product of the number of shares issuable upon exercise and the
Exercise Price, divided by the Market Value Per Share. For example, if Holder
receives a warrant to purchase 1,500,000 shares of Common Stock at an Exercise
Price of $1.00 and decides to use the "cashless exercise" method to exercise its
option to purchase all 1,500,000 shares at a time when the Company's Common
Stock has a Market Value Per Share of $10.00, Holder would receive 1,350,000
shares of Common Stock upon exercise. Upon surrender of this Warrant with the
annexed Notice of Exercise Form duly executed, together with payment of the
Exercise Price for the shares of Common Stock purchased, the Holder shall be
entitled to receive

<PAGE>

a certificate or certificates for the shares of Common Stock so purchased. For
the purposes of this Section 2, "Market Value" shall be an amount equal to the
average closing bid price of a share of Common Stock for the ten (10) days
preceding the Company's receipt of the Notice of Exercise Form duly executed
multiplied by the number of shares of Common Stock to be issued upon surrender
of this Warrant, and "Market Value Per Share" shall be an amount equal to the
average closing bid price of a share of Common Stock for the ten (10) days
preceding the Company's receipt of the duly executed Notice of Exercise Form.

                           (b)      For purposes of Rule 144 promulgated under
the Securities Act, it is intended, understood and acknowledged that the Warrant
Shares issued in a cashless exercise transaction shall be deemed to have been
acquired by the Holder and the holding period for the Warrant Shares shall be
deemed to have been commenced, on the issue date.

                  3.       RESERVATION OF SHARES. The Company hereby agrees that
at all times during the term of this Warrant there shall be reserved for
issuance upon exercise of this Warrant such number of shares of its Common Stock
as shall be required for issuance upon exercise of this Warrant (the "Warrant
Shares").

                  4.       MUTILATION OR LOSS OF WARRANT. Upon receipt by the
Company of evidence satisfactory to it of the loss, theft, destruction or
mutilation of this Warrant, and (in the case of loss, theft or destruction)
receipt of reasonably satisfactory indemnification, and (in the case of
mutilation) upon surrender and cancellation of this Warrant, the Company will
execute and deliver a new Warrant of like tenor and date and any such lost,
stolen, destroyed or mutilated Warrant shall thereupon become void.

                  5.       RIGHTS OF THE HOLDER. The Holder shall not, by virtue
hereof, be entitled to any rights of a stockholder in the Company, either at law
or equity, and the rights of the Holder are limited to those expressed in this
Warrant and are not enforceable against the Company except to the extent set
forth herein.

                  6.       PROTECTION AGAINST DILUTION.

                           6.1      ADJUSTMENT MECHANISM. If an adjustment of
the Exercise Price is required pursuant to this Section 6, the Holder shall be
entitled to purchase such number of additional shares of Common Stock as will
cause (i) the total number of shares of Common Stock Holder is entitled to
purchase pursuant to this Warrant, multiplied by (ii) the adjusted purchase
price per share (the "Adjusted Exercise Price"), to equal (iii) the total number
of shares of Common Stock Holder is entitled to purchase before adjustment
multiplied by the Exercise Price before adjustment. For example, if Holder
receives a warrant to purchase 1,500,000 shares of Common Stock at an Exercise
Price of $1.00, and the Adjusted Exercise Price is $0.50, Holder will be
entitled to receive 3,000,000 shares of Common Stock.

                           6.2      CAPITAL ADJUSTMENTS. In case of any stock
split or reverse stock split, stock dividend, reclassification of the Common
Stock, recapitalization, merger or consolidation, or like capital adjustment
affecting the Common Stock of the Company, the provisions of this Section 6
shall be applied as if such capital adjustment event had occurred immediately
prior to the date of this Warrant and the original purchase price had been
fairly allocated to the stock resulting from such capital adjustment; and in
other respects the provisions of this Section shall be applied in a fair,
equitable and reasonable manner so as to give effect, as nearly as may be, to
the purposes hereof.

                           6.3      ADJUSTMENT FOR SPIN OFF. If, for any reason,
prior to the exercise of this Warrant in full, the Company spins off or
otherwise divests itself of a part of its business or operations or disposes all
or of a part of its assets in a transaction (the "Spin Off") in which the
Company does not receive compensation for such business, operations or assets,
but causes securities of another entity (the "Spin Off Securities") to be issued
to security holders of the Company, then the Company shall cause (i) to be
reserved Spin Off Securities equal to the number thereof which would have been
issued if Holder had exercised its right to purchase all of the remaining Common
Stock available to Holder under this Warrant as of the close of business on the
trading day immediately before the record date (the "Outstanding Warrants") for
determining the amount of the number of Spin Off Securities to be issued to
security holders of the Company (the "Reserved Spin Off Shares"), and (ii) to be
issued to the Holder upon exercise of all or any of the Outstanding Warrants,
such amount of the Reserved Spin Off Shares equal to (x) the Reserved Spin Off
Shares multiplied by (y) a fraction, of which (I) the numerator is the amount of
the Outstanding Warrants then being exercised, and (II) the denominator is the
Outstanding Warrants.

                  7.       TRANSFER TO COMPLY WITH THE SECURITIES ACT;
REGISTRATION RIGHTS.

                  (a) This Warrant has not been registered under the Securities
Act of 1933, as amended, (the "Act") and has been issued to the Holder for
investment and not with a view to the distribution of either the Warrant or the
Warrant Shares. Neither this Warrant nor any of the Warrant Shares or any other
security issued or issuable upon exercise of this Warrant may be sold,
transferred, pledged or hypothecated in the absence of an effective registration
statement under the Act relating to such security or an opinion of counsel
satisfactory to the Company that registration is not required under the Act.
Each certificate for the Warrant, the Warrant Shares and any other security
issued or issuable upon exercise of this Warrant shall contain a legend on the
face thereof, in form and substance satisfactory to counsel for the Company,
setting forth the restrictions on transfer contained in this Section.

                  (b) The Company agrees to file a registration statement, which
shall include the Warrant Shares, on Form SB-2 or another available form (the
"Registration Statement"), pursuant to the Registration Rights Agreement between
the Company and Holder dated June   , 2000.
