                               PROSPECTUS SUMMARY

                                  THE COMPANY

     The Company is a bio-pharmaceutical company in the development stage
currently working on  a therapeutic treatment for male erectile dysfunction.
This product, tentatively designated as "PaGE(1)," consists of prostaglandin
("PGE-1," a natural occurring fatty acid) encapsulated in liposomes, which is
then lyophilized (freeze dried) to provide stability and a useful shelf life.
When needed for patient use, this lypholized microsphere is reconstituted using
a specially formulated detergent which lyzes the liposomes, releasing the
active substance, PGE-1.  The resulting liquid is then self-applied by the
patient using a soft catheter the Company has developed for this purpose.  The
catheter applies the liquid into the urethra of the penis via the urethral
meatus, with minimal risk of trauma to the patient.

     The Company is the assignee of Patent Application No. 08/573408, filed
December 15, 1995, for an invention "PGE-1 Containing Lyophilized Liposomes For
Use In The Treatment of Erectile Dysfunction."  This invention consists of the
encapsulation of prostaglandin in liposomes and the subsequent rupturing of
those liposomes with a dilute detergent diluent to release the prostaglandin
immediately prior to application.  The Patent Office has issued an Office
Action rejecting the application with comments, which comments the Company
believes can be responded to effectively. The Company, therefore, believes that
it will be able to pursue the application and believes it will be successful,
although there can be no assurance thereof.  See "Risk Factors-Uncertainty of
Patent Protection" and "Description of Business - Patents and Intellectual
Property."  The Company also filed an application for a European Patent for the
invention in December 1996.

     PGE-1 is already approved for the treatment of male erectile dysfunction
in an injectable formulation by Pharmacia/Upjohn and an intra urethral
insertion of a prostaglandin containing pellet by Vivus.  A locally applied
intra-meatal product could be advantageous to patient comfort when compared
with an injectable or a pellet insertion product.  In addition, lypholizing
extends the shelf life of PGE-1 at room temperature from less than two minutes
to three years.  Although PGE-1 has been approved for treatment, the use of the
specially formulated detergent to lyze the liposomes and the lyophilizing of
the liposome encapsulated PGE-1 require full registration with the Food and
Drug Administration ("FDA") of PaGE1 as a new drug.  An Investigative New Drug
application ("IND") was submitted to the FDA in May 1996 and the Phase I trial
to test safety and tolerance of PaGE1 with small group of subjects was
commenced.

     The Phase I trial has been concluded with the result that preliminary
efficacy data is available indicating the possible benefits of such a therapy.
These results were presented to the FDA in April 1997 as part of the Company's
pre-Phase II Clinical Trial meeting.  See "Description of Business - Government
Regulation."  Although this early data suggests product efficacy, there can be
no assurance that the PaGE1 will reach the market successfully.  The
manufacturing procedure is being scaled up, with assay verification and
validation in progress.  A New Drug Application will be filed with the FDA,
assuming adequate data is generated upon conclusion of the clinical trial
program.  There can be no assurance that the FDA will approve the product for
marketing.  It is estimated that the costs of completing the above procedures
will amount to between $10 to $12 million.  The FDA review process could last
as long as two (2) years and perhaps even longer in the event the FDA requires
Phase III trials or requests additional data.  See "Description of Business -
Government Regulation."

     The Company's future success is dependent upon its ability to raise
additional funds to complete the commercialization process for its erectile
dysfunction treatment product.  The Company intends to obtain these funds
through public and private financing or from other sources such as
collaboration agreements.  Although the Company has sold $5,000,000 principal
amount of Debentures and has an undertaking, subject to various conditions, to
raise an additional $10,000,000 principal amount of Debentures, there can be no
assurance that this additional funding will occur or be sufficient and that, if
this additional funding does not occur or is insufficient, other required funds
will be available or will be available on terms satisfactory to the Company.
Failure to obtain adequate financing could cause a delay or termination of the
Company's product development and marketing efforts.

<PAGE>   6


     Over the next 12 months, the Company's primary focus will be on continuing
clinical trials and product validation to conform to the regulatory process of
the FDA. Additionally, the Company will be identifying and seeking
collaborative arrangements with pharmaceutical distribution concerns and/or
licensing agreements with companies to eventually distribute PaGE1.

     The Company continues to look at other products it can add to its
portfolio that it believes have market potential.  In particular the Company
seeks to utilize medically researched and developed drug substances, to
determine the ability of these substances to be encapsulated in liposomes and
to determine the potential market for such products.

     Harvard Scientific Corp. was incorporated in Nevada in 1987 under the name
Witch Doctor Bones, Inc.  The Company's principal executive office is located
at 100 N. Arlington Avenue, Suite 23-P, Reno, Nevada, and its telephone number
is (702) 796-1173.  The Company has no contractual relationship or affiliation
with Harvard University.

                               CURRENT FINANCING

     In March 1997, pursuant to a private placement, the Company  (a) sold to
one investor $5,000,000 principal amount of 6% Convertible Debentures (the
"Debentures") and (b) received a commitment from that investor, subject to
various conditions, to purchase additional Debentures in the aggregate
principal amount of up to $10,000,000 in two tranches of $5,000,000 each. The
investor may convert the Debentures into Common Stock (the "Conversion
Shares").  The Conversion Shares constitute the Selling Securityholder's Common
Stock being offered and sold by the Selling Securityholder pursuant to this
Prospectus.  See "Description of Securities," "Management's Discussion and
Analysis of Financial Condition and Results of Operations - Liquidity and
Capital Resources" and "Selling Securityholder and Plan of Distribution."

but are not limited to, those discussed in "Risk Factors," "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business," as well as those discussed elsewhere in this Prospectus.


LIMITED OPERATING HISTORY AND REVENUES; SIGNIFICANT AND CONTINUING LOSSES;
UNCERTAINTY OF FUTURE PROFITABILITY

     The Company is a development-stage company.  Since inception, the Company
has been engaged primarily in the development of  PaGE1 and only commenced
limited use of PaGE1 in clinical trials in 1996.  Accordingly, the Company has
limited operating history upon which an evaluation of its performance and
prospects can be based.

     The likelihood of the success of the Company must be considered in light
of the risks, problems, expenses, difficulties and complications frequently
encountered in connection with a the shift from development to
commercialization of new products based on innovative technologies.  It should
be noted that, during the period from January 1994 to February 1995, the
Company also investigated, acquired, tested, and ultimately abandoned
technology related to whole blood rapid testing for viruses, particularly the
HIV.  The decision to abandon this technology was based on poor pre-marketing
results.

     Since inception, the Company has generated limited revenues and incurred
significant losses, including losses of $489,664, $676,455 and $1,938,944 for
the fiscal years ended December 31, 1994, 1995 and 1996, respectively.  Losses
are continuing through the date of this Prospectus and the Company anticipates
that it will continue to incur such losses until such time, if ever, as the
Company generates sufficient levels of revenues from product sales to offset
its operating costs.  The Company believes that generation of such revenues is
dependent upon, among other things, the Company's ability to obtain FDA
approval.  There can be no assurance the Company will be able to operate
profitably or be commercially successful.  See "Business".


SIGNIFICANT CAPITAL REQUIREMENTS; AUDITORS' GOING CONCERN REPORT; DEPENDENCE ON
OFFERING PROCEEDS; POSSIBLE ISSUANCE OF ADDITIONAL SECURITIES; FUTURE DILUTION

     The Company's capital requirements have been and will continue to be
significant, and the Company currently has very limited cash flow from
operations.  As a result, the Company has been dependent on equity and debt
financings.  The Independent Auditor's Report accompanying the Company's
financial statements for the years ended December 31, 1996, 1995 and 1994
states that, in light of the recurring losses suffered by the Company, its
continued existence depends upon its ability to resolve its liquidity problems.
See "Management's Discussion" and "Audited Financial Statements."

     Based on the Company's operating plan, internal forecasts and assumptions
(which include:  successful conclusion of clinical trials, rapid acceptance of
product due to ease and comfort of administration, price parity with competitor
products and continued growth of erectile dysfunction market niche as more
patients become aware of therapy for the problem) management believes that the
proceeds from the private placement of 6% Convertible Debentures in the
aggregate principal amount of $5,000,000 and in an additional principal amount
of $10,000,000 that has been committed and anticipated cash flow from
operations and other sources will be sufficient to meet the Company's
anticipated cash needs and finance its plans for growth.  In the event that the
Company's plans change, its assumptions change or prove inaccurate, its
revenues are less than anticipated, the commitment to purchase the


                                       6


<PAGE>   9


additional $10,000,000 principal amount of 6% Convertible Debenture or its
further financing otherwise prove insufficient to fund operations, the Company
may be required to seek additional financing.  No assurance can be given that
the Company will be successful in obtaining such additional financing, or if
obtained, that such financing will be on terms favorable to the Company.  Any
inability to obtain additional financing when needed and on acceptable terms
could have a material adverse effect upon the Company's operations, including
the possibility of requiring the Company to curtail or cease its operations.
In addition, any additional equity financing may involve substantial dilution
to the Company's then existing shareholders.  See "Use of Proceeds" and
"Management's Discussion."


DEPENDENCE UPON SALES OF PRINCIPAL PRODUCT; LIMITED CUSTOMER BASE

     The Company's future performance will depend, almost entirely, on the
successful development, introduction and customer acceptance of the Company's
principal product, PaGE1.  To date, substantially all of the Company's revenues
have been generated by the distribution of  PaGE1 for use in clinical trials
overseas.  The Company anticipates that, once FDA approval is obtained,
substantially all of its revenues for the foreseeable future will be generated
by sales of PaGE1, both overseas and in the U.S.  Although early clinical data
regarding the product suggests good probable efficacy, new product development
is highly uncertain and unanticipated developments, clinical and regulatory
delays, adverse or unexpected side effects or inadequate therapeutic efficacy
could slow or prevent the commercialization of PaGE1.  There can be no
assurance that the Company will not experience these or other difficulties that
could delay or prevent the commercialization of PaGE1 .  Furthermore, no
assurance can be given that, if commercialization is commenced, PaGE1 will meet
with market acceptance.  The inability to successfully commercialize PaGE1, for
any reason, would have a material adverse effect on the Company's financial
condition, prospects, and ability to continue operations.  See "Business."


GOVERNMENT REGULATION; UNCERTAINTY OF REGULATORY APPROVAL; UNCERTAINTY OF
PRODUCT DEVELOPMENT

     The Company is subject to various FDA regulations which govern or
influence the research, testing, manufacture, safety, labeling, storage,
recordkeeping and advertising and promotion of pharmaceutical products,
biologics, and medical devices.  Outside the United States the Company is
subject in most cases to similar regulation.  The Company believes it is in
substantial compliance with all FDA and other material federal and state laws
and regulations.  There can be no assurance, however, that the Company will be
able, for financial and other reasons, to comply with applicable laws, rules
and regulations.  Failure or delay by the Company to comply with applicable
regulatory requirements could subject the Company to civil remedies, including
fines, suspensions, delays of approvals, injunctions, recalls or seizures of
products, operating restrictions, as well as potential criminal sanctions,
which could have a material adverse effect on the Company.  See "Business -
Government Regulation."

     The Company's research, development, clinical trials, manufacturing and
marketing of PaGE1 are subject to extensive, rigorous and frequently changing
regulatory review process by the FDA and other regulatory agencies in the U.S.
and various foreign countries.  The process of obtaining and maintaining
required regulatory approvals is lengthy, expensive and uncertain.  FDA
procedures for approval of pharmaceuticals and biologics involve clinical
testing which occurs in three phases to demonstrate the safety and efficacy of
the product.   See "Business - Government Regulation."

     The Company expects that certain aspects of PaGE1 also may be regulated by
the FDA as Class III devices.  Preclinical evaluations of Class III devices are
similar to those of pharmaceuticals and biologics, with additional emphasis on
implant persistence, implant sensitization, and carrier characterization and
specifications. See "Business - Government Regulation."

     There can be no assurance that FDA or other regulatory clearance in the
United States and elsewhere will not take longer than currently anticipated
because of delays, problems or unforeseen safety difficulties.  Failure to
obtain FDA approval would prevent the Company from marketing PaGE1 in the U.S.,
which would have a material adverse effect on the Company's business, financial
condition and results of operations, and failure to obtain approval in key
markets outside the United States would also have a material adverse effect.
Even if regulatory approval is obtained, a marketed pharmaceutical product and
its manufacturer are subject to continuing regulatory


                                       7


<PAGE>   10


review, and discovery of previously unknown problems or amendments to existing
statutes or regulations or the adoption of new statutes or regulations could
result in restrictions on such product or manufacturer, including withdrawal of
the product from the market.  In addition, the FDA requires submission of a
pre-market approval ("PMA") notification for any change or modification to a
previously marketed product that significantly affects safety or effectiveness.
In addition, if the Company develops a different delivery device for PaGE1,
this device would be subject to FDA review procedures prior to release for
marketing.  See "Business - Government Regulation."


DEPENDENCE ON THIRD-PARTY RESEARCH

     The Company intends to use a significant portion of the proceeds of the
Debentures to conduct research and clinical studies, primarily for the purpose
of obtaining FDA approval for the marketing of PaGE1 in the U.S.  The Company
has to date conducted only Phase I trials with respect to PaGE1.  These trials
were conducted by two private, practicing urologists in Las Vegas, Nevada.  The
Company plans to continue to utilize third parties to conduct the necessary
clinical trials.  Several Clinical Research Organizations ("CRO"s) have
submitted bids for the clinical trials.  These are under review and a suitable
CRO will be selected shortly.  Therefore, the Company will be substantially
dependent upon third-party researchers and others, over whom the Company will
not have absolute control, to satisfactorily complete scientific studies
performed on behalf of the Company.  There can be no assurance that third
parties will be able to carry out these studies in the proper manner, within
the time frame, and within the cost estimates currently relied upon by
management.  In the event that the studies were carried out incorrectly or
improperly, or were not completed within the time frame currently contemplated,
or exceeded current cost parameters, the Company's business could be materially
adversely affected.   See "Business - Research and Development."


LACK OF MANUFACTURING EXPERIENCE AND CAPABILITIES; DEPENDENCE ON THIRD-PARTY
MANUFACTURING AND SUPPLIERS

     The Company does not own or lease any manufacturing facilities, does not
manufacture the product or any of its ingredients, and purchases all
ingredients from unaffiliated suppliers, including FDA validated suppliers of
the active ingredient, PGE-1.  The Company does not now have any contracts with
manufacturers, although it is in the process of negotiating such contracts.
Although the Company believes that there are adequate suppliers and
manufacturers sufficient to satisfy the Company's requirements, the terms on
which suppliers and manufacturers will be available could have a material
effect on the success of the Company.  See "Uncertainty of Supply of Key
Pharmaceutical Ingredient" and "Business - Manufacturing."


LIMITED SALES, MARKETING AND DISTRIBUTION EXPERIENCE; DEPENDENCE UPON THIRD
PARTY MARKETING EFFORTS

     The Company has limited marketing experience and limited financial,
personnel and other resources to independently undertake extensive marketing
activities.  The Company's prospects will be significantly affected by its
ability to develop and maintain a network of distributors.  Although the
Company had entered into four separate marketing agreements, all but one has
been terminated.  Moreover, the Company has generated only $181,000 in revenues
from the distribution agreements, primarily due to the fact that the product
has not yet received regulatory approval.  These revenues were derived from
reimbursement of production costs of clinical materials supplied to a
distributor for use in clinical trials.  To the extent that the Company enters
into third-party marketing and distribution arrangements, it is dependent on
the marketing efforts of such third parties and upon their provision of
installation and support services and the vagaries of changes in market
conditions.  While the Company believes that any third parties with which it
enters into marketing arrangements will have an economic motivation to
commercialize the Company's products, the time and resources devoted to these
activities will be controlled by such entities and not by the Company.  There
can be no assurance that the Company will be able, for financial or other
reasons, to finalize any third-party marketing arrangements or that such
arrangements, if finalized, will result in successful commercialization of the
product.




                                       8

COMPETITION; NO ASSURANCE OF MARKET FOR PRINCIPAL PRODUCT

     The market for treatment of male erectile dysfunction is emerging and
evolving and is characterized by an increasing number of entrants. Although
the Company is not aware of any other products which deliver prostaglandin in a
locally applied intra-meatal formulation, there are several other companies
which offer products designed to treat male erectile dysfunction.  The
competition is both direct (i.e., companies that produce prostaglandin using
alternative delivery mechanisms) and indirect (i.e., companies that produce
penile implants, vacuum constriction devices, and other alternative
treatments).  Prostaglandin is already FDA-approved for the treatment of male
erectile dysfunction in an injectable formulation by Pharmacia/Upjohn and in a
formulation using intra-urethral insertion of a prostaglandin-containing pellet
by Vivus.  Other companies, such as Pfizer and Zonagen, are currently
developing tablet formulations, and Macrochem is working on a topical solution.
See "Business - Competition."

     There can be no assurance that additional technologies or products which
are functionally similar to those of the Company are not currently under
development or that other companies with the expertise or resources that would
encourage them to attempt to develop or market competing products will not
develop new products directly competitive with PaGE(1) or that the Company can
complete clinical testing of PaGE(1), obtain regulatory approvals and commence
commercial-scale manufacturing in a timely manner to be competitively
effective.  Some of the Company's competitors and potential competitors have
well-established reputations for success in the development, sale and service
of medical equipment and have substantially greater financial, technical,
personnel and other resources than the Company, enabling them to undertake
clinical testing of products, obtain regulatory approvals and manufacture and
market pharmaceutical products in response to competitors seeking to market new
products and enter into new markets.  There can be no assurance that the
Company will be able to compete successfully, that competitors will not develop
technologies or products that render the Company's product obsolete or less
marketable, or that the Company will be able to successfully enhance its
existing product or develop or acquire new products or produce them at
competitive prices.  See "Business - Competition."

     The commercial success of PaGE(1) will require acceptance by urologists,
family practitioners with a significant elderly male clientele, and medical
doctors practicing as sex therapists and the medical community as a whole.
Such acceptance will depend in large part on the results of clinical trials and
the conclusion by these physicians that PaGE(1) is a safe, cost-effective and
acceptable method of treatment.  There can be no assurance that physicians will
be sufficiently encouraged by the results of the clinical trials to decide to
use the product.  They may elect to use other treatment methods and procedures
which they believe to be more efficient or to have advantages over PaGE(1).
Accordingly, achieving market acceptance for PaGE(1) will require substantial
marketing efforts and expenditure of significant funds to educate doctors,
pharmacists, and the public about what the Company believes are the advantages
and benefits of PaGE(1).  The majority of such marketing expenses are expected 

to be borne by the distributors.  However, the company expects to expend over
$3 million over the first few years of launch in supportive activities.  There
can be no assurance that such efforts will result in significant initial or
continued market acceptance for PaGE(1).  In addition, PaGE(1), being a complex
pharmaceutical product, may contain a number of side effects or other problems
that become apparent subsequent to widespread commercial use.  Remedying such
problems could delay the Company's plans and cause it to incur additional costs
that would have a material adverse effect on the Company.  See "Business -
Research and Development" and " - Sales and Marketing."


DEPENDENCE ON THIRD-PARTY REIMBURSEMENT

     Successful commercialization of PaGE(1) may depend in part upon the
availability of reimbursement for the cost of related treatment from
third-party healthcare providers, principally Medicare, Medicaid and private
health insurance plans, including health maintenance organizations.  To the
extent reimbursement is not provided or is limited, patients will have to pay
for the PaGE(1) out of their own pockets.  Third-party payers are increasingly
challenging the price of medical products and services, which have had and
could continue to have a significant effect on the purchasing patterns of many
healthcare providers.

     In markets other than the United States, reimbursement is obtained from a
variety of sources, including governmental authorities, private health
insurance plans and labor unions.  In most foreign countries, there are also
private insurance systems that may offer payments for alternative therapies.
Although not as prevalent as in the


                                       9


<PAGE>   12


U.S., health maintenance organizations are emerging in some European countries.
Accordingly, the Company may need to seek reimbursement approvals in such
other countries, although there can be no assurance that any such approvals
will be obtained in a timely manner or at all.  Failure to receive
reimbursement approvals in such other countries could have an adverse effect on
market acceptance of the Company's product in those international markets in
which such approvals are sought.

     The Company believes that reimbursement will be subject of increased
restrictions in the future in the U.S. and foreign markets.  The overall
escalating cost of medical products and services has led to and will likely
continue to lead to increased pressures on the health care industry to reduce
the costs of products and services, potentially including products offered by
the Company.  Significant uncertainty generally exists as to the reimbursement
status of newly approved healthcare products.  Failure to receive adequate
levels of reimbursement for the use of prostaglandin in general, and PaGE1 in
particular, could have a material adverse effect on the Company's business,
financial condition and results of operations.


UNCERTAINTY OF PATENT PROTECTION; UNCERTAINTY OF PROTECTION OF PROPRIETARY
TECHNOLOGY

     The strength of the Company's patent position may play an important role
in its long-term success.  The Company is the assignee of Patent Application
No. 08/573408, filed December 15, 1995, for an invention "PGE-1 Containing
Lyophilized Liposomes For Use In The Treatment of Erectile Dysfunction."  The
Patent Office has issued an Office Action rejecting the application with
comments, which comments the Company believes can be met so that it can go
forward with the application.  However, there can be no assurance that any
patents in fact will be issued  as a result of this application or that, if
issued, such patent or patents will be effective to protect the Company's
product from duplication by others.  In addition, there can be no assurance
that the Company will be able to afford the expense of any litigation which may
be necessary to enforce its rights under any patent.  Moreover, although the
Company believes that its product does not and will not infringe upon the
patents or violate the proprietary rights of others, it is possible that such
infringement or violation has or may occur.  In the event that the Company's
product is determined to infringe upon the patents or proprietary rights of
others, the Company could be required to modify its product or obtain a license
for the manufacture and/or sale of the product, or could be prohibited from
selling the product.  There can be no assurance that, in such an event, the
Company would be able to do so in a timely manner, upon acceptable terms and
conditions, or at all, and the failure to do any of the foregoing could have a
material adverse effect upon the Company.  Furthermore, there can be no
assurance that the Company will have the financial or other resources necessary
to enforce or defend a patent infringement or proprietary rights violation
action.  In addition, if the Company's product is deemed to infringe upon the
patents or proprietary rights of others, the Company could, under certain
circumstances, become liable for damages, which could also have a material
adverse effect on the Company.   See "Business - Patents and Intellectual
Property."

     The Company also relies substantially upon its proprietary technologies,
utilizing non-disclosure agreements with its employees, consultants and
customers to establish and protect the ideas, concepts and documentation of its
proprietary technology and know-how.  Such methods, however, may not afford
complete protection, and there can be no assurance that third parties will not
independently develop such know-how or obtain access to the Company's know-how,
ideas, concepts and documentation, which could have a material adverse effect
on the Company.


POTENTIAL PRODUCT LIABILITY EXPOSURE AND INSURANCE EXPENSE; CURRENT LACK OF
PRODUCT LIABILITY INSURANCE

     Upon the commencement of commercial production, the Company's business
will expose it to an inherent risk of potential product liability claims,
including claims for serious bodily injury or death, which could lead to
substantial damage awards.  The Company currently maintains product liability
insurance in the amount of $1,000,000, with a maximum payout of $3,000,000,
which is the standard insurance coverage for the biopharmaceutical industry.
The Company will seek to increase the level of such insurance as its products
are commercialized.  There can be no assurance, however, that the Company will
be able to maintain or increase its insurance on acceptable terms or at
reasonable costs, or that such insurance will provide the Company with adequate
coverage against potential liabilities.  A successful claim brought against the
Company in excess of, or outside of, its insurance coverage could have a
material adverse effect on the Company's results of operations and financial


                                       10


<PAGE>   13


condition.  Claims against the Company, regardless of their merit or eventual
outcome, may also have a material adverse effect on the Company's ability to
obtain physician endorsement of its products or expand its business.


RELIANCE ON INTERNATIONAL SALES; CURRENCY EXCHANGE RISKS ASSOCIATED WITH
INTERNATIONAL SALES

     The Company anticipates marketing PaGE1 internationally, as well as in the
U.S.  To the extent the Company is able to market its product in foreign
countries, the Company will become subject to the risks associated with
international sales, including, but not limited to, health and welfare
regulatory controls imposed by foreign governments, shipping delays, customs
duties, export quotas and other trade restrictions, increased collection risks
and international political, regulatory and economic developments, and exchange
risks, any one of which could have an adverse effect on the Company's operating
results.  See "Management's Discussion."


DEPENDENCE ON KEY PERSONNEL

     The Company is dependent on the efforts and abilities of Jackie R. See,
M.D., its founder, Head of Research and Development and Director; of Ian Hicks,
its Chairman of the Board, President, Chief Executive Officer and Director; of
Don A. Steffens, its Chief Financial Officer, Secretary, Treasurer and
Director, and of Jeremii Wesolowski, Ph.D., its Chief Operating Officer.
Unforeseen circumstances could cause one or more of these individuals to be
unable to render his or their services to the Company.  The loss of the
services of any such officers or other key personnel could have a material
adverse effect on the Company's operations.

     In addition, to date, the Company has relied extensively on the services
of management and technical staff from its parent company, BTI. This technical
and management assistance has been provided as part of the consideration for
the issuance of the Company's stock, but there is no specific agreement between
the Company and BTI in this regard.  There can be no assurance that BTI will
continue to provide such technical and management assistance, or if provided,
on terms acceptable to the Company, which if not provided could have a material
adverse effect on the Company's operations.  To the extent that the services of
key personnel become unavailable, the Company will be required to retain other
qualified persons, for whose services the Company will be in competition with
other employers, many of which have significantly greater resources than the
Company.  There can be no assurance that the Company will be able to hire or
retain such other qualified persons.  See "Management's Discussion."


LACK OF BUSINESS INTERRUPTION INSURANCE

     The Company does not currently maintain business interruption insurance
coverage.  The Company is a development stage concern at this time.  It relies
on a few key employees to direct and administrate the activities of the
Company.  See "Dependence on Key Personnel."  The Company outsources most
aspects of its operations, except administration.  See "Dependence on
Third-Party Research," "Dependence on Third-Party Manufacturing and Suppliers"
and "Dependence on Third-Party Marketing Efforts."  There can be no assurance
that the Company will be able to either obtain cost effective insurances,
diversify its outsourced functions, or maintain a core group of effective
personnel sufficiently adequate to protect the Company's financial condition.


BARRIERS TO TAKEOVER

     The Company's Certificate of Incorporation and By-Laws contain certain
provisions which may deter, discourage, or make more difficult the assumption
of control of the Company by another corporation or person through a tender
offer, merger, proxy contest or similar transaction or series of transactions.
These provisions include an unusually large number of authorized shares
(100,000,000) and the prohibition of cumulative voting.  The overall effect of
these provisions may be to deter a future tender offer or other takeover
attempt that some stockholders might view to be in their best interest as the
offer might include a premium over the market price of the Company's capital
stock at the time.  In addition, these provisions may have the effect of
assisting the Company's current management in retaining its position and place
it in a better position to resist changes which some


                                       11


<PAGE>   14


stockholders may want it to make if dissatisfied with the conduct of the
Company's business.  See "Description of Securities -- Nevada Law and Corporate
Provisions Affecting Shareholders."


LIMITATIONS ON LIABILITY OF DIRECTORS AND OFFICERS

     Section 78.751 of the Nevada General Corporation Law ("NGCL") allows the
Company to indemnify any person who is or was made a party to, or is or was
threatened to be made a party to, any pending, completed, or threatened action,
suit or proceeding by reason of the fact that he or she is or was a director,
officer, employee or agent of the Company or is or was serving at the request
of the Company as a director, officer, employee or agent of any corporation,
partnership, joint venture, trust or other enterprise.  The NGCL permits the
Company to advance expenses to an indemnified party in connection with
defending any such proceeding, upon receipt of an undertaking by the
indemnified party to repay those amounts if it is later determined that the
party is not entitled to indemnification.

     The foregoing provision may reduce the likelihood of derivative litigation
against directors and officers and discourage or deter shareholders from suing
directors or officers for breaches of their duties to the Company, even though
such an action, if successful, might otherwise benefit the Company and its
shareholders.  In addition, to the extent that the Company expends funds to
indemnify directors and officers, funds will be unavailable for operational
purposes.  See "Description of Securities -- Nevada Law and Corporate
Provisions Affecting Shareholders."


VOLATILITY OF THE COMPANY'S COMMON STOCK PRICES

     The market price of the Company's Commons Stock has experienced
significant volatility, with per share bids ranging from a low of $.25 to a
high of $16.63 over the period from the second quarter of 1995 to December 31,
1996.  Various factors and events, including announcements by the Company or
its competitors concerning patents, proprietary rights, technological
innovations or new commercial products, as well as public concern about the
safety of medical products and practice in general, may have a significant
impact on the Company's business and the price of the Company's Common Stock.


EFFECT OF DEBENTURE CONVERSION

     Upon conversion of the Debentures there will be not less than 13,702,042
shares of Common Stock  outstanding, consisting of 11,403,129 shares currently
outstanding and a minimum of 2,298,1850 shares (and potentially substantially
more depending upon the Market Price at the time of conversion) issuable upon
conversion by the Debentures available for offer by the Selling Shareholders,
which shares will be tradable without restriction or further registration under
the Securities Act of 1933, as amended (the "Securities Act"), as long as the
prospectus covering such sales remains current and effective.  No prediction
can be made as to the effect, if any, that future sales of shares of Common
Stock whether offered by the Selling Securityholder or others will have on the
market price of the shares of Common Stock prevailing from time to time.  Sales
of substantial amounts of Common Stock, or the perception that these sales
could occur, could adversely affect prevailing market prices for the Common
Stock and could impair the ability of the Company to raise additional capital
through the sale of its equity securities or through debt financing.  See
"Market for Common Equity and Related Stockholder Matters."


ILLIQUID MARKET RISKS RELATING TO LOW-PRICED STOCKS

     The Common Stock of the Company is currently traded on the system of the
National Association of Securities Dealers, Inc., known as the OTC Electronic
Bulletin Board under the symbol "HVSF."  This market generally is not as liquid
as the market for NASDAQ equity securities or exchange-listed securities, and
discounts and transactional costs may be greater than in the more liquid
markets.  In addition, the trading price of the Common Stock has fallen below
$5.00 per share at various times during the past years and may do so in the
future, at which price trading in the Common Stock is subject to the
requirements of certain rules promulgated under the


                                       12


<PAGE>   15


Exchange Act, which require additional disclosure by broker-dealers in
connection with any trades involving a stock defined as a penny stock
(generally, any non-NASDAQ equity security that has a market price of less than
$5.00 per share, subject to certain exceptions).  Such rules require the
delivery, prior to any penny stock transaction, of a disclosure schedule
explaining the penny stock market and the risks associated therewith and impose
various sales practice requirements on broker-dealers who sell penny stocks to
persons other than established customers and accredited investors.  The
additional burdens imposed upon broker-dealers by such requirements could, in
the event the Common Stock were deemed to be a penny stock, discourage
broker-dealers from effecting transactions in the stock, which could severely
limit the market liquidity of the Common Stock and the ability of purchasers in
this offering to sell the stock in the secondary market.


TRANSACTIONS WITH CONTROLLING PERSONS; POTENTIAL CONFLICTS OF INTEREST

     In consideration of the assignment of the intellectual property rights to
patent, develop, manufacture and market the PaGE1, the Company issued 2,856,000
shares of common stock to its parent company, BTI. The Company also issued a
further 6,138,500 shares of common stock with BTI for BTI's assistance in
raising working capital, prosecuting the patent application, management
assistance, and for assignment of rights under four distribution agreements for
the PaGE1 product.  BTI owned 63% of the Company's outstanding shares as of
December 31, 1996.  11,000,000 of BTI's shares, or 44% are owned by Jackie R.
See, M.D., who is also the Company's founder, Head of Research and Development
and a Director.  Dr. See also has potential voting rights on another 2,000,000
BTI shares.

     During 1994, the Company paid $$150,000 to related parties for work
performed in completing a merger with Grant City Corporation ("GCC"), which was
effected in 1993.  Of this amount, $100,000 was paid to BTI and the remaining
$50,000 was paid to individuals affiliated with BTI.  The Company has entered
into a royalty agreement with Dr. See, whereby it will pay Dr. See two percent
(2%) of gross proceeds.  During 1997, the Company transferred 1,250,000 shares
to related parties as compensation for services previously rendered, including
350,000 shares to Dr. See.

     The foregoing arrangements and relationships may give rise to conflicts of
interest with respect to future interpretation of the agreements between the
Company, BTI and Dr. See.  There can be no assurance that future transactions
or arrangements between the Company and any affiliates will be advantageous to
the Company, although the Company intends to enter into transactions with BTI
or Dr. See only if they are at least as favorable to the Company as could be
could be obtained from independent third parties.  See "Dependence on Key
Personnel,"  "Dependence on Third-Party Researchers," "Business - Research and
Development," "Management's Discussion" and "Certain Transactions."


PENDING LITIGATION

                           DESCRIPTION OF SECURITIES


COMMON STOCK

     The Company's authorized stock consists of 100,000,000 shares of Common
Stock, $.001 par value.  As of the date hereof, there were 11,403,129 shares of
Common Stock outstanding, which were held of record by 180 stockholders.  The
Company's shares are listed on the  NASD OTC Electronic Bulletin Board under
the symbol "HVSF".

     Holders of Common Stock are entitled to one vote for each share held of
record on all matters submitted to a vote of the stockholders.  Holders of
Common Stock are not entitled to cumulative voting rights.  Holders of Common
Stock are entitled to receive ratably such dividends as may be declared by the
Board of Directors out of funds legally available therefor.  In the event of a
liquidation, dissolution or winding up of the Company, holders of Common Stock
are entitled to share ratably in all assets remaining after payment of
liabilities.  Holders of Common Stock have no preemptive rights and no right to
convert their Common Stock into any other securities.  There are no redemption
or sinking fund provisions applicable to the Common Stock.  All the outstanding
shares of Common Stock are validly issued, fully paid and nonassessable.

     The Company has not paid any dividends on its Common Stock since its
inception and does not contemplate or anticipate paying any dividends on its
Common Stock in the foreseeable future.  Earnings, if any, will be used to
finance the development and expansion of the Company's business.


6% CONVERTIBLE DEBENTURES

     The Company's 6% Convertible Debentures ("Debentures") bear an interest
rate of six percent (6%) per annum and mature on March 30, 1998 as to the
$5,000,000 principal amount of Debentures currently outstanding and as of the
end of the first anniversary month of the issuance of the two additional
$5,000,000 trenches of Debentures that the Selling Shareholder has agreed to
purchase.  See "Use of Proceeds from Sale of Debentures."  The Debentures are
issuable in denominations of $100,000 and integral multiples thereof and, at
the holder's request, are exchangeable for an equal aggregate principal amount
of debentures of different authorized denominations.  Upon maturity of the
Debentures, payment for principal and accrued interest will be made either in
currency or in shares of the Company's Common Stock, at the option of the
holder.

     The holder may convert the Debentures into Common Stock commencing on the
effective date of this Registration Statement.  The conversion price per share
will be either  (a) $6.525, the Market Price as defined in the Debentures as of
March 21, 1997, or (b) 80% of the Market Price on the date of conversion,
whichever is lower.  "Market Price," as used herein, means the average closing
bid price of the Common Stock on the five (5) trading days immediately
preceding March 21, 1997 or Conversion Date as may be applicable, as reported
by the National Association of Securities Dealers, or the closing bid price on
the over-the-counter market on such date or, in the event the Common Stock is
listed on a stock exchange or traded on NASDAQ, the Market Price means the
closing price on the exchange on such date, as reported in the Wall Street
Journal.  The Company has the option to pay the interest accrued from the date
of issuance to the date of conversion either in cash or in shares of Common
Stock.

     The Company may redeem any Debentures for which a Notice of Conversion has
not been submitted if the conversion price equals or is less than $1.60 per
share by delivering a Notice of Redemption to the holder.  However, the holder
may still opt to convert any such Debentures into shares of Common Stock by
submitting a Notice of Conversion to the Company within three business days of
the holder's receipt of the Company's Notice of Redemption.

     The redemption price will be 125% of the principal amount of the
Debentures, plus accrued unpaid interest.  The Company must pay the redemption
price to the holder within ten days from the date of the Notice of Redemption.
If the Company fails to make the redemption payment within these ten days, the
Company forfeits its right to redeem those Debentures.



                                       14


<PAGE>   17


     A holder may also require the Company to declare whether it intends to
effect a redemption within the following ten days by faxing a notice to the
Company.  The Company must respond to this notice within 24 hours.  If it fails
to do so, the Company may not redeem that holder's Debentures during the ten
day period commencing 24 hours after the date of the notice from the holder.

     If the Company merges or consolidates with another corporation or sells or
transfers all or substantially all  of its assets to another person and, as a
condition of such merger, consolidation or sale, the holders of the Company's
Common Stock are entitled to receive stock or securities in another corporation
or to receive property in exchange for the Company's Common Stock, then the
Debenture may be converted into the kind and amount of stock, securities or
property receivable by the holders of the Company's Common Stock pursuant to
the transaction.  If, within 15 days of the holder's receipt of a notice from
the Company advising of a proposed merger, consolidation or sale, the holder
has not submitted a Notice of Conversion, then the Company may prepay all
outstanding principal and accrued interest and thereby terminate the holder's
conversion rights.



            MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

     The capital stock of the Company began trading on the system of the
National Association of Securities Dealers, Inc. (NASD) known as the OTC
Electronic Bulletin Board under the symbol "HVSF" in June 1995 and continues to
be traded thereon as of the effective date of this Prospectus and Registration
Statement.

     The following table sets forth the range of high and low bid quotations
for the Company's capital stock for each quarterly period indicated, as
reported by brokers and dealers making a market in the capital stock.  Such

                              REGISTRATION RIGHTS

     In connection with the Company's private placement of $5,000,000 principal
amount of 6% Convertible Debentures on March 21, 1997, the Company was required
to prepare and file, within 30 days of such date, a registration statement
under the Securities Act for 300% of the number of shares of Common Stock
issuable upon the exercise of the Conversion rights calculated as of the time
of filing the registration statement and assuming the entire $15,000,000
principal amount of Debentures had been issued.  Timely filing of the
registration statement has been made.  The Company is obligated to use its best
efforts to cause the registration statement to become effective by June 19,
1997 and to keep the registration statement effective for two years or until
the Selling Securityholder


                                       15


<PAGE>   18


may sell all registerable securities under Rule 144 or until the Selling
Securityholder no longer owns any registerable securities, whichever occurs
first.  The Company is further obligated to register and qualify the securities
under such state securities laws as the Investors may request subject to
specified limitations.  The Company will bear the reasonable expenses of the
registration and qualification of the shares under the Securities Act and State
Securities laws other than any underwriting discounts and commissions and legal
fees in excess of $3,500.

     If the Registration Statement is not effective by June 19,1997, then the
Company will make payments to the Selling Securityholder in such amounts and at
such times as determined pursuant to Section 2(c) of the Registration Rights
Agreement, which states that the amount to be paid by the Company to the
Selling Securityholder shall be determined as of each Computation Date, and
such amount shall be equal to two percent (2%) of the purchase price paid by
the Selling Securityholder for the Debenture for the period from the Initial
Date to the first Computation Date, and three percent (3%) of the purchase
price for each Computation Date thereafter, to the date the Registration
Statement is declared effective by the SEC, except to the extent any delay in
the effectiveness of the Registration Statement occurs because of an act of, or
a failure to act or to act timely, by the Selling Securityholder or its
counsel.  "Computation Date" means the date which is the earlier of (a) 35 days
after the Company is notified by the SEC that the Registration Statement may be
declared effective or (b) July 19, 1997, and, if the Registration Statement has
not theretofore been declared effective by the SEC, each date which is thirty
(30) days after the previous Computation Date until such Registration Statement
is so declared effective.


                POSSIBLE EFFECT OF FUTURE SALES OF COMMON STOCK

     Upon consummation of this offering, the Company will have 15,424,577
Shares of Common Stock outstanding, assuming the sale of $15,000,000 principal
amount of Debentures, and further assuming the conversion of all the
Debentures, at a Market Price (as defined in the Debentures) of the Common
Stock of $4.6625, the Market Price on April 14, 1997, of which the Common Stock
offered hereby will be freely tradable without restriction or further
registration under the Securities Act.  Most of the remaining Shares
outstanding are held by Affiliates (as defined below) of the Company and may
only be sold pursuant to an effective registration under the Securities Act, in
compliance with the exemption provisions of Rule 144 promulgated under the
Securities Act or pursuant to another exemption under the Securities Act, such
as Regulation S. "Affiliates" of the Company include all executive officers and
directors of the Company and all other persons that directly, or indirectly
through one or more intermediaries, control, or are controlled by, or are under
common control with, the Company.

     In general, under Rule 144, subject to the satisfaction of certain other
conditions, a person, including an Affiliate of the Company (or persons whose
shares are aggregated with an Affiliate) who has owned restricted shares of
Common Stock beneficially for at least two years is entitled to sell, within
any three-month period, a number of shares that does not exceed the greater of
1% of the then outstanding shares of the issuer's Common Stock or the average
weekly trading volume during the four calendar weeks preceding such sale,
provided that certain public information about the issuer as required by Rule
144 is then available and the seller complies with certain other requirements.
Affiliates must sell such shares in compliance with Rule 144 regardless of the
holding period requirement.  A person who is not an Affiliate, has not been an
Affiliate within three months prior to sale, and has beneficially owned the
restricted shares for at least three years is entitled to sell such shares
under Rule 144 without regard to any of the limitations described above.

     No prediction can be made as to the effect, if any, that market sales of
Common Stock, including the Conversion Shares, or the availability of such
shares for sale will have on the market price prevailing from time to time.
Nevertheless, the possibility that substantial amounts of Common Stock may be
sold in the public market may adversely effect prevailing market prices for the
Common Stock and could impair the Company's ability to raise capital through
the sale of its equity securities.


           NEVADA LAW AND CORPORATE PROVISIONS AFFECTING SHAREHOLDERS

     The Company's Certificate of Incorporation and By-laws contain certain
provisions which may deter, discourage, or make more difficult the assumption
of control of the Company by another corporation or person


                                       16


<PAGE>   19


through a tender offer, merger, proxy contest or similar transaction or series
of transactions.  These provisions include an unusually large number of
authorized shares (100,000,000) and the prohibition of cumulative voting.  The
overall effect of these provisions may be to deter a future tender offer or
other takeover attempt that some stockholders might view to be in their best
interest as the offer might include a premium over the market price of the
Company's capital stock at the time.  In addition, these provisions may have
the effect of assisting the Company's current management in retaining its
position and place it in a better position to resist changes which some
stockholders may want it to make if dissatisfied with the conduct of the
Company's business.  See "Risk Factors - Anti-Takeover Provisions."

     Furthermore, Section 78.751 of the Nevada General Corporation Law ("NGCL")
allows the Company to indemnify any person who is or was made a party to, or is
or was threatened to be made a party to, any pending, completed, or threatened
action, suit or proceeding by reason of the fact that he or she is or was a
director, officer, employee or agent of the Company or is or was serving at the
request of the Company as a director, officer, employee or agent of any
corporation, partnership, joint venture, trust or other enterprise.  The NGCL
permits the Company to advance expenses to an indemnified party in connection
with defending any such proceeding, upon receipt of an undertaking by the
indemnified party to repay those amounts if it is later determined that the
party is not entitled to indemnification.

     The foregoing provisions may reduce the likelihood of derivative
litigation against directors and officers and discourage or deter shareholders
from suing directors or officers for breaches of their duties to the Company,
even though such an action, if successful, might otherwise benefit the Company
and its shareholders.  In addition, to the extent that the Company expends
funds to indemnify directors and officers, funds will be unavailable for
operational purposes.  See "Risk Factors - Indemnification of Officers and
Directors."


                          TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the Common Stock is Nevada Agency and
Trust Company, Reno, Nevada.



                    USE OF PROCEEDS FROM SALE OF DEBENTURES

     None of the proceeds from the sale of the Common Stock registered
hereunder will accrue to the Company.

     Through private placement, the Company has obtained $5,000,000 of
financing in the form of 6% Convertible Debentures.  The holder of these
Debentures, who is also the Selling Securityholder, has agreed to purchase an
additional $10,000,000 aggregate principal amount of Debentures in two tranches
of $5,000,000 each commencing not less than 60 days after the effective date of
the Registration Statement of which this Prospectus is a part, subject to (i)
the effectiveness of the Registration Statement of which this Prospectus is a
part, (ii) the continuing material accuracy of specified representations and
warranties of the Company to the Selling Securityholder and (iii) the Market
Price of the Common Stock for the five trading days prior to the purchase of
the tranches exceeds $3.50.

     The Company intends to apply the net proceeds of the Debentures to
conclude the process/manufacturing validation, to fulfill FDA requirements for
the submission of a New Drug Application and to fulfill the requirements for
foreign regulatory approval of PaGE(1), estimated to be $10,000,000 to
$12,000,000.

     The Company believes that its existing available resources, the net
proceeds of the Debentures, anticipated up-front and milestone payments from
strategic distribution partners, and revenues from sales of clinical materials
under the IND and for use in overseas clinical trials should be sufficient to
fund its operating expenses until it reaches positive cash flow, although there
can be no assurance thereof.  The amount and timing of expenditures will depend
upon the progress of the clinical trials, the terms of any collaborative
arrangements entered into by the Company for licensing and distribution, the
timing of receipt of regulatory approvals, if any, and other factors,


                                       17


<PAGE>   20


many of which are beyond the Company's control.  The Company reserves the right
to allocate the net proceeds among the foregoing uses.  See "Business -
Strategic Alliances, Collaborations and Licenses."

     Pending such uses, the net proceeds will be invested in short-term,
interest bearing securities.



                                 CAPITALIZATION

     The following table sets forth, as of December 31, 1997, the actual
capitalization of the Company, as adjusted to reflect the sale of $15,000,000
principal amount of Debentures and as further adjusted to reflect the
conversion of all the Debentures, assuming that the Market Price (as defined in
the Debentures) of the Common Stock on the date of conversion of the Debentures
was $4.6625, the Market Price on April 14, 1997 and excluding current
liabilities of $535,223.  The table should be read in conjunction with the
Audited Financial Statements and notes thereto appearing elsewhere in this
Prospectus.

                SELLING SECURITYHOLDERS AND PLAN OF DISTRIBUTION

     As of the date of this Prospectus, the Selling Securityholder owned
$5,000,000 principal amount of 6% Convertible Debentures, had committed to
purchase an additional $10,000,000 of Debentures, and held no shares of Common
Stock.  Upon conversion of the Debentures, the Selling Securityholder will
acquire shares on the basis set forth in the following paragraph, provided
however, that the Selling Securityholder can never own more than 4.9% of the
outstanding shares.  (See note(1), in Common Stock Ownership of Certain
Beneficial Owners and Management.)

     The Company has agreed to register the public offering of the Selling
Securityholder's shares of Common Stock under the Securities Act and to pay all
expenses in connection therewith other than brokerage commissions


                                       18


<PAGE>   21


and discounts in connection with the sale of the Conversion Shares and the
expenses of counsel for the Selling Securityholder in excess of $3,500.  The
aggregate number of Conversion Shares that may be offered and sold pursuant to
this Prospectus by the Selling Securityholder will be determined by how many
shares are issued upon conversion of the Debentures, which will be determined
by the conversion price applicable to the Conversion Shares.  See "Description
of Securities."  The conversion price for a Conversion Share will be the lesser
of the Market Price (as defined in the Debentures) on March 21, 1997, which was
$6.525, and 80% of the Market Price on the Conversion Date of the Debenture
with respect to such share.  Assuming that the Market Price on the date of
Conversion is $4.6625 (which is the Market Price calculated as of April 14,
1997) with respect to all the Debentures, and that all the Debentures are
converted, the aggregate number of Conversion Shares issued would be 4,021,448,
and if all the Conversion Shares are issued, the Selling Shareholder would have
no beneficial interest in the Common Stock of the Company, assuming that the
Selling Shareholder did not acquire a beneficial interest in the Common Stock
of the Company otherwise than through the conversion of the Debentures.

     The Selling Securityholder's Shares may be offered and sold from time to
time as market conditions permit in the over-the-counter market, or otherwise,
at prices and terms then prevailing or at prices related to the then-current
market price, or in negotiated transactions.  The Selling Securityholder's
Shares may be sold by one or more of the following methods, without limitation:
(i) a block trade in which a broker or dealer so engaged will attempt to sell
the share a s agent but may position and resell a portion of the block as
principal to facilitate the transaction; (ii) purchases by a broker or dealer
as principal and resale by such broker or dealer for its accounts pursuant to
this Prospectus; (iii) ordinary brokerage transactions and transactions in
which the broker solicits purchases; and (iv) transactions between sellers and
purchasers without a broker or dealer.  In effecting sales, brokers or dealers
engaged by the Selling Securityholder may arrange for other brokers or dealers
to participate.  Such brokers or dealers may receive commissions or discounts
from Selling Securityholder in amounts to be negotiated.  Such brokers and
dealers and any other participating brokers and dealers may be deemed to be
"underwriters" within the meaning of the Securities Act, in connection with
such sales.



                            DESCRIPTION OF BUSINESS

     The Company was incorporated under the laws of the State of Nevada on
January 13, 1987 with the name of Witch Doctor Bones, Inc.  On August 12, 1987,
the Company qualified a public offering under Rule 504 of Regulation D of the
Securities Act of 1933, as amended, with the Secretary of State of Nevada. On
June 17, 1988, the Company changed its name to Careyward, Inc. and authorized a
forward split of ten (10) shares for one (1).

     On October 18, 1993, the Company acquired Grant City Corporation by a
merger.  As a result thereof, 50,000 shares were issued which carried two
classes of warrants.  Class A warrants entitled the holder to purchase stock at
$8.00 per share and the Class B warrants entitled the holder to purchase stock
for $10.00 per share.  The warrants could only be exercised if a registration
statement was in effect filed with the United States Securities and Exchange
Commission pursuant to the Securities Act of 1933, as amended.  No such filing
has been made by the Company.  Both classes of warrants have been redeemed by
the Company at $0.001 per warrant with twenty (20) days written notice.  Thus,
the warrants have been canceled.

     On January 6, 1994, the Company entered into an Asset Purchase Agreement
with Bio-Sphere Technologies, Inc. ("BTI") whereby the Company acquired
intellectual property rights relating to prostaglandin microsphere delivery in
exchange for 2,856,000 shares of the Company's Common Stock.  As a result of
this transaction, the Company became a subsidiary of BTI.

     On January 18, 1994, the name of the Company was changed to The Male Edge,
Inc.  On May 10, 1994, the name of the Company was changed to Harvard
Scientific Corp.

     The Company is a development stage bio-pharmaceutical company engaged in
the development of a product for the treatment of male erectile dysfunction.
On February 13, 1996, the Company received an assignment of an application for
a patent identified as Application Serial No. 08/573408, filed December 15,
1995, for an invention "PGE-1 Containing Lyophilized Liposomes For Use In The
Treatment of Erectile Dysfunction."  The


                                       19


<PAGE>   22


assignment was made by the holder of the application, BTI, which owns a
majority of the Company's issued and outstanding stock.  The assignment states
that BTI sold, assigned, transferred and set over to the Company "the entire
right, title and interest" in the application for the PGE-1 invention.  The
Company understands this to mean that the assignment in question is exclusive.
The Company also filed an application for a European Patent in December 1996.

     The Company's principal product, PaGE(1), is a lyophilized liposomal
formulation of Prostaglandin E-1 ("PGE-1") in which the PGE-1 is encapsulated
in liposomes and then lyophilized (freeze dried).  This provides the product
with stability, the shelf life of which is expected to exceed three years at
room temperature.  The lyophilized material is reconstituted through the use of
a non-irritating dilute detergent, which lyses the liposomes, releasing the
PGE-1 into solution.  This solution is then applied via the urethral meatus
(the opening at the end of the urethral tract at the tip of the penis).

     PGE-1 is an oxygenated, unsaturated cyclic fatty acid which occurs
naturally in all cells of the body.  It has already been approved by the FDA
for therapeutic use as an intravenous infusion in newborn babies with
congenital heart defects.  PGE-1 has also been approved by the FDA for the
treatment of male erectile dysfunction, as an injection and as an
intra-urethrally administered pellet.  However, the use of the specially
formulated detergent to lyze the liposomes and the lyophilizing of the
liposome-encapsulated PGE-1 require full registration of PaGE(1) with the FDA as
a new drug.  Accordingly, the Company filed an IND application with the FDA in
May 1996.  PaGE(1) has undergone a Phase I clinical study, the results of which
indicated the possible benefits of such therapy and provided the Company with
sufficient information for the recommendation of two doses of the product to be
developed for marketing, as well as an indication of the safety of the product.
The study's results will be presented at the annual American Urology
Association meeting in New Orleans in April 1997.

     The Company continues to qualify products in development within BTI to
determine safety, effectiveness, market potential, and time and cost to
commercialization.  In addition, the Company is looking into existing
pharmocological agents of other pharmaceutical companies which could be made
more effective by utilizing the Company's delivery system technology.  As of
this date, the Company is concentrating its personnel and financing resources
exclusively on its erectile dysfunction treatment and has no immediate plans to
add additional products to the Company's commercialization and marketing
efforts.


                                   THE MARKET

     Male erectile dysfunction ("ED") occurs when there is a persistent
inability to achieve an erection sufficient to permit sexual intercourse.  It
is not a loss of desire or the ability to experience orgasm.  In about 60% of
cases a medical condition such as diabetes, vascular disease, high blood
pressure or a neurological disorder is found to be interfering with the
erection process.  An estimated additional 25% of cases occur due to
medications such as anti-hypertensive medications.  Smoking and excessive
drinking of alcohol may also contribute to the condition.  The remaining 15% of
cases may have some form of psychological difficulty, including anxiety and
stress.  Often there is a combination of factors at work.

     PGE-1 is absorbed across the urethral mucosa into the corpus spongiosum.
Some of the dose enters the corpora cavernosum, while some of the dose goes
into pelvic veinous circulation.  The half life varies from 30 seconds to 10
minutes, although intra-urethrally administered product is barely discernable
in circulation.  Alprostadil causes the smooth muscle relaxation in the penile
corpora and vasodilation of the arteries.  This results in rapid filling of the
corpora with blood which causes the compression of corporal sinusoids against
the tunica albuginea, impeding venous outflow.  The result is the development
of an erection.

     According to the Consensus Report of the American Medical Association, ten
to twenty percent of men in the United States suffer from erectile dysfunction.
The market for treatments for ED, such as PaGE(1), is expected to grow over the
next few years as more men become comfortable with the fact that ED is
treatable.  The aging of the male population as the so-called "Baby Boomers"
enter middle age is also expected to expand the market, since incidence of ED
is likely to increase with a man's age.

                                  COMPETITION

     The market for treatment of ED is emerging and evolving and is
characterized by an increasing number of entrants.  The company faces
competition from a number of existing and potential competitors.
Pharmacia/Upjohn, Schwartz Pharma and Senetek each produce PGE-1 in injectable
formulation.  Upjohn's product has received regulatory approval worldwide,
Schwartz Pharma's product is approved for use in Europe, and Senetek's product
has received FDA approval for sale in the United States.

     The product most similar to the Company's product is produced by Vivus.
It consists of a pellet containing PGE-1 which is released into the urethra via
the specialized MUSE(R) device designed specifically for this purpose.  This
product has the potential for side effects, including dizziness, drop in blood
pressure and pain at application

     There are tablet formulations of erectile dysfunction products
(phentolamine and sildanafil) currently in Phase III of clinical testing.  The
tablet formulations have potential benefits for patients who suffer from mild
dysfunction problems.  However, they could present various undesirable side
effects which must be overcome.  Pfizer and Zonagen are the two known
competitors developing tablet formulations.

     Another competitor, Macrochem is currently undertaking Phase I clinical
trials of a topical solution containing PGE-1.

     Other forms of competition are penile implants and vacuum pumps.  However,
the Company anticipates that the market for these devices will decline with the
increasing awareness of various drug formulations which provide a more natural
erection.

     Although the Company is not aware of any additional technologies or
products which are functionally similar to those of the Company currently under
development, there can be no assurance that such technologies or products will
not be developed or that other companies with the expertise or resources that
would encourage them to attempt to develop or market competing products will
not develop new products directly competitive with PaGE(1).  Some of the
Company's competitors and potential competitors have well-established
reputations for success in the development, sale and service of
biopharmaceuticals and have substantially greater financial, technical,
personnel and other resources than the Company, enabling them to undertake
clinical testing of products, obtain regulatory approvals and manufacture and
market pharmaceutical products in response to competitors seeking to market new
products and enter into new markets.  In addition, there can be no assurance
that the Company can complete clinical testing of PaGE(1), obtain regulatory
approvals and commence commercial-scale manufacturing in a timely manner to be
effectively competitive.


                          PRODUCTION AND MANUFACTURING

     The Company's product will be manufactured by two third party
manufacturers located in Southern California.  The manufacturers will produce
the Company's product per the Company's directions and specifications and
deliver the product to the Company.  The Company sees no reason to acquire the
equipment necessary for production at this time and anticipates utilizing its
existing current arrangement with outside laboratories for the manufacturing of
its products for distribution.

     The Company anticipates that the ingredient from which PaGE(1), will be
manufactured will be supplied by Sigma Chemical Company, Austin Chemical Co.,
Inc., Spectrum Chemical Company, Interchem Corporation and West Company.

     The Company is not aware of any environmental issues related to the use of
disposal of its product.  The chemistry involved produces no damaging effects
on human, animal or plant life if exposed to the general population's air,
water or soil supply.  The Company's previous manufacturer Collaboration
Laboratories did not disclose or relate any information indicating that the
manufacturing process would produce any environmentally harmful by-products.




                                       21


<PAGE>   24


                                   MARKETING

     The commercial success of PaGE(1) will require acceptance by urologists,
family practitioners with a significant elderly male clientele, medical doctors
practicing as sex therapists and the medical community as a whole.  Such
acceptance will depend in large part on the results of clinical trials and the
conclusion by these physicians that PaGE(1) is a safe, cost-effective and
acceptable method of treatment.  Accordingly, achieving market acceptance for
PaGE1 will require substantial marketing efforts and expenditure of significant
funds to educate doctors, pharmacists, and the public about what the Company
believes are the advantages and benefits of PaGE(1).  To that end, the Company 
is currently negotiating distribution agreements with major international
pharmaceutical companies delivering the United States, European and South
American market.  As is customary in the biopharmaceutical industry, operating
in these market the Company anticipates that these distribution agreements will
provide for the distributor to pay the Company up-front licensing fees and
milestone payments.  In addition, the distributor will be responsible for the
costs of registration and/or FDA approval and validations.  Despite these
arrangements, the Company expects to expend over $3 million over the first few
years of launch in marketing support activities.


                                   EMPLOYEES

     As of December 31, 1996, the Company had two full time employees.  These
full time employees are engaged in management and administrative activities.
None of the Company's employees are subject to a collective bargaining
agreement and the Company believes its relations with its employees are good.
From time to time, the Company elicits the services of management and technical
staff from its parent company, Bio-Sphere Technology, Inc. ("BTI").  The
Company reimburses BTI for time contributed directly by its employees in
providing technical and scientific services and assistance to the Company.


                             GOVERNMENT REGULATION

     The Company is subject to various FDA regulations which govern or
influence the research, testing, manufacture, safety, labeling, storage,
recordkeeping and advertising and promotion of pharmaceutical products,
biologics, and Class II devices.  The Company believes it is in substantial
compliance with all material federal and state laws and regulations.  There can
be no assurance, however, that the Company will be able, for financial and
other reasons, to comply with applicable laws, rules and regulations.  Failure
or delay by the Company to comply with FDA regulations or other applicable
regulatory requirements could subject the Company to civil remedies, including
fines, suspensions, delays of approvals, injunctions, recalls or seizures of
products, operating restrictions, as well as potential criminal sanctions,
which could have a material adverse effect on the Company.

     The Company's research, development, clinical trials, manufacturing and
marketing of PaGE1 are subject to extensive, rigorous and frequently changing
regulatory review process by the FDA and other regulatory agencies in the U.S.
and various foreign countries.  The process of obtaining and maintaining
required regulatory approvals is lengthy, expensive and uncertain.  FDA
procedures for approval of pharmaceuticals and biologics involve clinical
testing which occurs in three phases to demonstrate the safety and efficacy of
the product.  Phase I clinical trials consist of testing for the safety and
tolerance of the product with a small group of subjects and may also yield
preliminary information about the effectiveness and dosage levels of the
product.  Phase II clinical trials involve testing for efficacy, determination
of optimal dosage, and identification of possible side effects in a larger
patient group.  Phase III clinical trials consist of additional testing for
efficacy and safety with an expanded patient group.  Upon successful completion
of Phase III testing, a New Drug Application ("NDA") can be filed.  Approval
requires a review of detailed data resulting from the clinical studies, the
composition of the drug, the labeling that will be used, information on
manufacturing methods, and samples of the products.  After the FDA completes
its review of the application, the product is typically reviewed by a panel of
medical experts, and the applicant is required to answer questions regarding
its safety and efficacy.  At the recommendation of the panel, an NDA may be
granted and the product may then be marketed.  After the product has been
approved for marketing, Phase IV post-marketing surveillance studies may be
required to provide additional data to the FDA for longer term follow-up
concerns.



                                       22


<PAGE>   25


     The Company submitted an Investigative New Drug ("IND") application to the
FDA in May 1996 and has concluded its Phase I trial. The results of the Phase I
trial are being assembled for presentation to the FDA in April 1997 as part its
pre-Phase II clinical trial meeting.  The manufacturing procedure is being
scaled up, with assay verification and validation in progress.  The Company
anticipates that an NDA will be filed with the FDA in late 1998, assuming
adequate data is generated upon conclusion of the clinical trial program.  It
is estimated that the costs of competing the above procedures for approval by
the FDA will cost $10,000,000 to $12,000,000.  The FDA review process could
last as long as two years and perhaps be even further extended in the event
that the FDA requires additional data.

     The Company expects that certain of its potential products also may be
regulated by the FDA as Class II devices upon completion of clinical testing.
This application must contain data demonstrating the safety of the product for
human use, information on manufacturing processes and procedures.  A 510(k)
will be filed with the FDA at the time of the NDA submission.  Class II devices
also cover urological catheters.

     There can be no assurance that FDA or other regulatory clearance will not
take longer than currently anticipated because of delays, problems or
unforeseen safety difficulties.  Failure to obtain FDA approval would prevent
the Company from marketing PaGE1 in the U.S. which would have a material
adverse effect on the Company's business, financial condition and results of
operations.  Even if regulatory approval is obtained, a marketed pharmaceutical
product and its manufacturer are subject to continuing regulatory review, and
discovery of previously unknown problems or amendments to existing statutes or
regulations or the adoption of new statutes or regulations could result in
restrictions on such product or manufacturer, including withdrawal of the
product from the market.  In addition, the FDA requires submission of a
pre-market approval ("PMA") notification for any change or modification to a
previously marketed product that significantly affects safety or effectiveness.

     The distribution of the Company's products outside the United States will
also be subject to extensive government regulation.  These regulations,
including the requirements for approvals or clearance to market, and the time
required for regulatory review and the sanctions imposed for violations, vary
from country to country.  There can be no assurance that the Company will
obtain regulatory approvals in such countries or that it will not be required
to incur significant costs in obtaining or maintaining its foreign regulatory
approvals.  Failure to obtain necessary regulatory approvals, the restriction,
suspension or revocation of existing approvals or any other failure to comply
with regulatory requirements would prevent the Company from marketing PaGE1 in
such foreign country or countries, which would have a material adverse effect
on the Company's business, financial condition and results of operations.

     The manufacturing processes of the Company's product will be subject to
certain regulatory guidelines.  These guidelines are laid down by the FDA.  All
pharmaceutical manufacturers must conform to these guidelines.  The FDA
inspects these facilities on a regular basis and any deficiencies are notes.
The facility must correct those deficiencies within a finite period of time.

     Any new pharmaceutical facility must go through a strict inspection by the
FDA, in a full audit, and then adhere to the guidelines.  Any facility not
adhering to these guidelines is subject to FDA regulatory action.
See "Business - Research and Development."


                           COLLABORATIVE ARRANGEMENTS

     The Company operates as a "virtual company" and relies on subcontracting
and collaborative arrangements for its research and development, manufacturing,
clinical trial and marketing operations.  Since January 1994, when BTI acquired
the majority of the Company's Common Stock, the Company has relied extensively
on management, technical and financial services provided by BTI.

     The Company has paid BTI for the PaGE1 patent application, as well as
licensing and distribution agreements and utilization of its scientific and
technical personnel, with Company stock.  The Company initially issued 714,000
shares (as currently restated) to BTI in January 1994 for the intellectual
rights to the product with the stipulation that the company pay for and effect
a patent application.  The Company was not able to fund the patent process.  In
order to protect its primary assets, a reorganization agreement between BTI and
the Company was


                                       23


<PAGE>   26


structured in 1995 and culminated in November whereby BTI received 6,138,500
additional shares of the Company for funding the patent application and other
benefits to the Company mentioned above.

     The Company reimburses BTI for the time contributed by its employees.  The
Company paid Bio-Sphere Technology, Inc. $40,501 in overhead expenses incurred
in 1994, $67,979 in 1995 and $80,000 in 1996.

     Furthermore, the Company intends to continue to seek and enter into
collaborative arrangements with pharmaceutical distribution concerns to
eventually distribute PaGE1.


                               LEGAL PROCEEDINGS

     1. Harvard Scientific Corp. v. Nevada Agency and Trust Company and Thomas
E. Waite & Associates, Case No. CV96-0495, Second Judicial District Court of
Nevada, County of Washoe, filed August 2, 1996.  This action involved a dispute
over performance of an agreement between the Company and a consultant, Thomas
E. Waite & Associates ("Waite"), who had been issued 350,000 shares of Common
Stock in exchange for services to be performed by Waite.  Those services
involved obtaining the financing for the Company.  In this action, the Company
claimed that Waite had not performed those services and had breached its
agreement with the company.  Nevada Agency and Trust Company, the Company's
transfer agent, was included as a defendant in order to enjoin the transfer of
the 350,000 shares which had been issued to Waite.  The Company sought to
recover damages for Waite's breach of contract and obtain a declaratory
judgment declaring the agreement between the Company and Waite null and void,
and canceling the shares issued to Waite.  The action was settled amicably
between the parties and is no longer pending.

     2a. Harvard Scientific Corp. v. Ailouros Ltd., Case No. CV-N-97-00088-HDM,
Second Judicial District Court of the State of Nevada, County of Washoe, filed
February 6, 1997, removed to United States District Court for the District of
Nevada.  This action concerns 7% Convertible Debentures the Company executed in
favor of the defendant in June 1996.  The Company claimed the defendant had
breached its contract with the Company regarding the terms of resale for the
Debentures and conversion shares issued pursuant thereto and that the defendant
had breached its duty of good faith and fair dealing in connection with the
entering into and performance of the agreement underlying the Debentures.  The
Company also alleged that an accord and satisfaction had been reached between
the parties on their dispute, and that such accord and satisfaction should be
enforced by the Court.  The Company also sought damages for the breach of the
underlying contract terms.

     On or about March 10, 1997, the Company filed an amended complaint which
added a cause of action seeking to have any shares previously issued to
Ailouros, as well as any shares which may be issued to Ailouros in the future
pursuant to the Debenture agreement which is the subject of this action, be
issued pursuant to the requirements of Regulation S due to the fact that at the
time the Company entered into its agreement with Ailouros, the Company's Form
10 filing had not yet become effective and therefore the Company was not a
reporting company.  This litigation is still pending.

     2b. Ailouros Ltd. v. Harvard Scientific Corp., Case No. CV-N-97-00089-ECR,
United States District Court for the District of Nevada, filed February 13,
1997.  In this action Ailouros claimed that the Company had breached the
Debenture agreement which is the subject of the action brought by the Company
against Ailouros referred to above.  Ailouros claimed it is entitled to 263,225
shares of the Registrant's common stock and/or is entitled to damages in the
amount of $2,000,000.  Ailouros sought to have its suit against the Company and
the Company's suit against Ailouros consolidated.  The Company does not oppose
such consolidation.  This litigation remains pending.

     3a. Harvard Scientific Corp. v. D. Weckstein and Co., Inc., and Donald E.
Weckstein, Case No. CV-97-00806, Second Judicial District Court of Nevada,
County of Washoe, filed February 10, 1997.  This action involves an agreement
between the Company and a consultant, pursuant to the terms of which the
defendants agreed to help the Company obtain financing in exchange for 25,000
shares of the Company's common stock.  In this action, the Company alleges that
defendants breached their agreement to help the Company obtain financing and/or
were negligent in performing their duties in helping the Company obtain
financing.  The complaint also alleges that


                                       24


<PAGE>   27


the defendants breached the covenant of good faith and fair dealing and
misrepresented their expertise, know-how, contacts and experience in order to
induce the Company to enter into the agreement that is the subject of this
action.

     3b. D. Weckstein and Co., Inc. v. Harvard Scientific Corp. and Thomas E.
Waite & Associates, Inc., Index No. 97-103324, Supreme Court of New York,
County of New York, filed February 18, 1997.  In this action, Weckstein claims
that the Company breached the same agreement which is the subject of the action
filed by the Company against Weckstein in Nevada.  Weckstein also seeks damages
against Thomas E. Waite & Associates, claiming that Thomas E. Waite &
Associates tortiously interfered with the agreement between the Company and
Weckstein.  Weckstein also seeks damages for alleged fraud on the part of
Thomas E. Waite & Associates, in connection with its dealings with Weckstein.

     Weckstein has also brought a cause of action against the Company for
"abuse of process" in connection with the filing of the Nevada action brought
by the Company against Weckstein.  In this claim, Weckstein asserts that the
Nevada Court has no personal jurisdiction over either of the defendants to the
Nevada action, and that the Company brought the action in Nevada simply to
inconvenience Weckstein.  This litigation has been settled amicably between the
parties and is no longer pending.

     4. Rex Morden v. Harvard Scientific Corp. and Does I through X, Case No.
A371111, District Court of Nevada, County of Clark, filed March 17, 1997.  In
this action, the plaintiff, a former officer of the Company, alleges that the
Company failed to pay when demanded the principal amount and accrued interest
of a Promissory Note executed by the Company on March 1, 1995 and due on
demand.  The plaintiff seeks damages of $42,275 (the principal amount of the
Note) plus interest accrued at the rate of 8% per annum.  The plaintiff also
seeks attorneys fees and costs.

     In addition to these lawsuits, the Company is negotiating with its
European marketer, Pharma Maehle, to terminate its licensing and marketing
agreement.  The Company also has noted some possible irregularities pertaining
to a Regulation "S" debenture in June 1996 and has taken steps to rectify this
matter.

     MANAGEMENT'S DISCUSSION AND ANALYSIS OF PLAN OF OPERATION

     The discussion contained in this Item 6 is "forward looking", as that term
is identified in, or contemplated by, Section 27A of the Securities Act and
Section 21E of the Exchange Act.  Accordingly, actual results may materially
differ from projections.  Additional information concerning factors that could
cause actual results to differ materially is readily available in this item.


OVERVIEW:

     Harvard Scientific Corp., is a bio-pharmaceutical development company.
The Company's corporate objective is to utilize medically researched and
developed drug substances, determine the ability of these substances to be
encapsulated in liposomes and to determine the potential market for such
products. The company will ensure development, regulatory testing and Federal
Drug Administration (FDA) processing to the point of distribution.  The Company
is currently working on only one product--a therapeutic treatment for male
erectile dysfunction.  The Company is assembling the results of its Phase I
clinical study for presentation to the FDA in April 1997 as part of its
pre-Phase II clinical trial meeting. During 1994, 1995 and 1996, the Company's
activities consisted primarily of raising capital, identifying a core
management team, developing a patent application, concluding manufacturing
scale up and initial clinical trials and formulating both a commercialization
and clinical development strategy.

     The Company continues to look at other products it can add to its
portfolio that it believes has market potential.

     The Company's future success is dependent upon its ability to raise
additional funds to complete the commercialization process for its erectile
dysfunction treatment product.  The Company intends to obtain these funds
through public and private financing or from other sources such as
collaboration agreements.  There can be no assurance that such funds will be
available or will be available on satisfactory terms to the Company.  Failure
to obtain adequate financing could cause a delay or termination of the
Company's product development and marketing efforts.

     Over the next 12 months, the Company's primary focus will be on continuing
clinical trials and product validation to conform to the regulatory process of
the FDA.  The Company believes that an 18 to 24 month time-line to obtain
regulatory approval is the current assumption, but there can be no assurance,
if ever, that the product will receive FDA approval in that time span.
Additionally, the Company will be identifying and seeking collaborative
arrangements with pharmaceutical distribution concerns and/or licensing
agreements with companies to eventually distribute the erectile dysfunction
product.

     The Company's success is dependent on its ability to raise additional
capital to effect all aspects of its operations.

     In the next twelve months, the Company has no plans to purchase or sell
any significant capital assets in the form of either plant or equipment, with
the exception of office equipment and furnishings to effect its administrative
activities.


RESULT OF OPERATIONS:

FOR THE PERIOD FROM JANUARY 13, 1987 (INCEPTION) THROUGH DECEMBER 31, 1993:

     The Company is in the development stages and has had limited operating
revenues since its inception on January 13, 1987.  During this period, the
Company's activities consisted primarily of reviewing business opportunities
and acquisitions, as well as maintaining the business entity.  During 1987 and
1988, the Company realized limited revenues from wholesaling activities
unrelated to its current planned operations.  The Company had


                                       27


<PAGE>   30


no operational activity form fiscal years 1989 through 1993 and all expenses
incurred during that period were related solely to maintaining the entity and
reviewing possible business opportunities.  Therefore, the Company has had a
limited history of operation.  From January 13, 1987 through December 31, 1993,
the Company had an accumulated deficit of $60,722.


FOR THE YEAR ENDED DECEMBER 31, 1994:

     On January 7, 1994, the Company acquired intellectual property rights from
Bio-Sphere Technology, Inc. for the treatment of male erectile dysfunction.
The Company issued 2,856,000 shares (714,000 shares as currently restated) to
acquire this technology.  Subsequently, the Company offered a private placement
memorandum to qualified investors to fund the further development and
commercialization of this product.  The capital raised totaled $354,150 net of
issuance cost during this period.

     At this same time, the Company investigated and eventually acquired an
additional intellectual property and technology related to whole blood rapid
testing for viruses, particularly the HIV virus.  At the time, the Company felt
the addition of this new product line was valuable to the Company in two ways.
First, the technology was qualified as the best available testing device for
both accuracy and ease of use in the marketplace.  Second, it provided the
Company with diversity in its potential product line, reducing the risks
associated with a single product company.

     In July of 1994, the Company purchased the property rights to the HIV
testing technology that would permit the improvement of the existing product of
the Disease Detection International and Trinity Biotech, Ltd. companies.  The
Company issued 1,340,000 shares (335,000 shares as currently restated) to three
individuals for those property rights.  Two of those individuals were directors
and the third was the son of one of the directors of the Company.

     In July 1994, the Company entered into a joint venture research and
development agreement with Disease Detection International, Inc., a Delaware
corporation, and its current parent, Trinity Biotech, Ltd., an Irish
corporation, for the improvement and enhancement of the rapid whole blood HIV
test device.  The agreement calls for complimentary marketing rights and a
50/50 split of the profits on any products produced as a result of this
agreement.  Subsequently, in August of 1994, the two companies signed a
marketing agreement further defining the manufacturing, pricing and patent
rights to the new product.

     After several months of pre-marketing of this rapid detection device, the
Company determined that approval by the marketing authority in the United
States was not likely due to adverse psychological reactions by private testing
patients.  Trinity Biotech, Ltd. terminated the agreements in February of 1995.
The Company contributed $34,470 directly to the research and development cost
of this product.  At this time, the Company has not taken any action in this
matter and has abandoned the project with Trinity Biotech, Ltd.

     The Company incurred a net loss for the year ended December 31, 1994 in
the amount of $489,664.  General and administrative expenses consisted
primarily of salaries of corporate officers, directors fees, office staffing
accounting, legal and marketing-related expenses, rent and occupancy costs.
Research and development cost consisted primarily of reimbursements to our
parent company for expenditures to consultants, patent attorneys, lab costs and
product sampling materials necessary to formulate the treatment for erectile
dysfunction.  Inclusive in the Company's research and development for 1994 was
the expenditure of $34,470 with regard to the HIV testing research and
development program.


FOR THE YEAR ENDED DECEMBER 31, 1995:

     In 1995, the Company experienced an increase in both general and
administrative expenses, as well as research and development expenses.  The net
loss for the year ended December 31, 1995 amounted to $676,455.  The total
operating expenditures for the two years ended December 31, 1995 represented
approximately 97% of the total operating expenses from inception, primarily due
to the fact that the Company was not operational prior to that time and all
expenses incurred form inception to the end of 1993 were primarily to maintain
the Company's status.



                                       28


<PAGE>   31


     In 1995, the Company's activities centered around raising capital.  The
Company started the year with a cash balance of $724.  The only capital
available for most of the year was provided through loans from the Company's
directors and others.  These moneys were primarily used to attempt to raise
investment capital and maintain the corporate entity.

     In November of 1995, the Company exchanged 6,138,500 shares of its common
stock with its parent company, Bio-Sphere Technology, Inc. (BTI) for patent
assignment necessary to strengthen its position on the treatment of male
erectile dysfunction.  In addition, BTI assigned licensing and distribution
contracts associated with the Company's impotency treatment.  BTI agreed to
make scientific and technical, as well as to provide management and marketing
personnel, available for the Company's use and to assist in raising working
capital.

     As a result of this reorganization, the Company raised $831,300, net of
issuance cost, on December 29, 1995.  These proceeds were used to fund the
Company's existing operations and retire a portion of loans and note payables
incurred earlier in the year.


FOR THE YEAR ENDED DECEMBER 31, 1996:

     The Company experienced an increase in administrative and general
expenses, including research and development costs.  The Company experienced a
management change in December 1996.  The net loss for the year ending December
31, 1996 amounted to $1,938,944.

     During 1996 the Company's activities centered around continued fund
raising efforts and development of the product. The Company started the year
with a cash balance of $799,466. The Company raised funds though a Regulation
"S" debenture in June 1996. The Company submitted an IND to the FDA and
concluded a Phase I clinical trial.


RISK FACTORS:

     The Company has identified at least two sources as  contract manufacturers
for its product.  The product under development by the Company has never been
manufactured on a commercial scale and there can be no assurance that such a
product can be manufactured at a cost or in quantities necessary to make it
commercially viable.

     The Company has engaged a clinical research organization to develop and
strategize on completing the FDA regulatory process.  The Company's long-term
success is predicated  on the strength of its patent position.  The Company is
the exclusive assignee of a U.S. patent application for the therapeutic remedy
of male erectile dysfunction.  The Company relies on trade secrets and
unpatented proprietary technology in producing its product.

     The competition for the product of the Company is primarily Upjohn and
Vivus and secondarily other treatments for male erectile dysfunction, including
penile implants and vacuum systems.

     Another uncertainty is the dependence on key personnel familiar with the
manufacturing process.  The loss of any of the Company's key scientific
personnel could have an adverse effect on the Company's continued product
development and business operations.


GENERAL:

     Industry experts estimate that erectile dysfunction in one form or another
afflicts nearly 50,000,000 men world-wide.  This number is expected to increase
as the male population increases its life expectancy and the current "baby
boom" generation ages.  Erectile dysfunction becomes more prevalent as men get
older.



                                       29


<PAGE>   32


     If the Company's product receives the appropriate regulatory approvals,
which is not certain, the Company expects to be able to capitalize on this
trend.  Estimates of funding needed to pursue the regulatory process run as
high as $15,000,000.  In the short term, this is likely to retard liquidity as
the Company's capital needs will increase.

     The Company expects to obtain capital funds either from the issuance of
common stock or debt.  It is expected that external sources will be available
to provide these funds, but there can be no guarantees of such funding.

(1)  The ownership of the shares deemed to be held by Springrange Investment
     Group, Ltd., the Selling Securityholder, due to its ownership of
     $5,000,000 principal amount of Debentures and its right to acquire an
     additional $10,000,000 principal amount of Debentures is not reflected due
     to Springrange's contractual obligation to the Company pursuant to which
     it is not entitled to convert any Debenture to the extent that after such

     owned through any continuing ownership of Debentures) exceeds 4.9% of the
     outstanding Common Stock.  The conversion price will be adjusted and the
     number of shares beneficially owned and being offered by the Selling
     Securityholder will vary in accordance with the terms of the Debentures to
     reflect changes in the Market Price of common stock, stock dividends,
     stock splits, and certain other circumstances.  See "Description of

Agreement with BTI under which this transaction took place, the Company's

standard comparative conventional methods of assessment--income, replacement
cost and industry comparables.  The component parts of the property were

                       EXPERTS AND CHANGE IN ACCOUNTANTS

     The financial statements of the Company included in this prospectus for
the years ended December 31, 1996 and 1995 have been audited by Dale McGhie,
independent certified public accountant, as set forth in his report thereon
appearing elsewhere herein.  Mr. McGhie's report includes an explanatory
paragraph stating that, in light of the recurring losses suffered by the
Company, its continued existence depends upon its ability to resolve its
liquidity problems.

     The Company's former accountant, Fair, Anderson & Langerman, was replaced
by W. Dale McGhie, Certified Public Accountant, 1539 Vasser Street, Reno,
Nevada 89502, as the Company's independent accountant in connection with the
financial statements for the year ended December 31, 1996.  Fair, Anderson &
Langerman did not resign and did not decline to stand for re-appointment.  They
were replaced because the Company's


                                       35


<PAGE>   38


headquarters were moved to Reno, Nevada, where Mr. McGhie is located, from Las
Vegas, Nevada, where Fair, Anderson & Langerman is located, and the Company
believed that it would be more efficient and effective to use Mr. McGhie as a
Reno-based accountant.  The decision to change accountants was recommended and
approved by the Board of Directors.

     Fair Anderson & Langerman's report on the financial statements for the
years ended December 31, 1995 and 1994 was presented on the assumption that the
Company would continue as a going concern and was unqualified.  There were no
disagreements with that firm on any matter of accounting principles or
practices, financial statement disclosure, or auditing scope or procedure,
which, if not resolved to Fair, Anderson & Langerman's satisfaction, would have
caused that firm to make reference to the subject matter of any such
disagreements in connection with its reports.

                          INDEPENDENT AUDITOR'S REPORT


To the Board of Directors
     and Shareholders of
Harvard Scientific Corp.

I have audited the balance sheet of Harvard Scientific Corp. (A Development
Stage Company) as of  December 31, 1996, and 1995, and the related statements
of operations, stockholders' equity, and cash flows for each of the years in
the three-year period ended December 31, 1996.  These financial statements are
the responsibility of the Company's management.  My responsibility is to
express an opinion on the financial statements based on my audits.

I have conducted my audit in accordance with generally accepted auditing
standards.   Those standards require that I plan and perform the audits to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  I believe that my audits provide a reasonable basis
for my opinion.

In my opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of  Harvard Scientific Corp. as
of December 31, 1996, and 1995, and the results of its operations and its cash
flows for each of the years in the three-year period ended December 31, 1996,
in conformity with generally accepted accounting principles.

The accompanying financial statements have been presented assuming that the
company will continue as a going concern.  As discussed in Note 11 to the
financial statements, the Company has suffered recurring losses from operations
that raises substantial doubt about its ability to continue as a going concern.
The financial statements do not include any adjustments that might result from
the outcome of this uncertainty.

NOTE 1 - NATURE OF BUSINESS AND  ORGANIZATION

NATURE OF BUSINESS:

Harvard Scientific Corp. (the "Company")  is a development stage company.  The
Company's  primary business operations consist of development,
commercialization, marketing, and distribution of  products relating to
prostaglandin/microsphere delivery and the way in which the product is applied
in treating male sexual dysfunction.  The Company has preliminary data
available, indicating the possible benefits of such a therapy.

On February 13, 1996, the Company received an assignment of an application for
a patent entitled "PGE-1 Containing Lyophilized Liposomes For Use In The
Treatment of Erectile Dysfunction" and identified as United States Application
No.  08/573,408 ("PGE-1").  The assignment was made by the holder of the
application, Bio-Sphere Technology, Inc. ("BTI"), the Company's majority
shareholder.  The Company plans to focus its operations on PGE-1 in order to
bring the product to the marketplace.

ORGANIZATION:

The Company  was incorporated under the laws of the State of Nevada on January
13, 1987, under the name  of Witch Doctors Bones, Inc.  On August 12, 1987, the
Company qualified a public offering under Rule 504 of Regulation D of the
Securities Act of 1933, as amended, with the Secretary of State of Nevada.  On
June 17, 1988, the Company changed its name to CareyWard, Inc.

On October 18, 1993, the Company acquired Grant City Corporation by merger,
changed its name to Grant City Corporation, and issued 50,000 shares of stock
carrying two classes of warrants.  Class A warrants entitled the holder to
purchase stock at $8.00 per share and the Class B warrants entitled the holder
to purchase stock for $10.00 per share.  The warrants could only be exercised
if a registration statement was filed with the United States Securities and
Exchange Commission  ("SEC") pursuant to the Securities Act of 1933 as amended.
The warrants were redeemable by written notice of twenty (20) days at a
redemption price of $.001 per  warrant.   During 1996, before the warrants
could be exercised, the Company gave the required notice and redeemed both
classes of warrants.

On January 18, 1994, the Company changed its name to The Male Edge, Inc.  On
May 10, 1994, the Company changed its name to Harvard Scientific Corp.

The Company has 100,000,000 shares of common stock authorized with 9,883,129
shares issued and outstanding as of December 31, 1996.  The Company had
8,749,124 shares issued and outstanding on December 31, 1995.  BTI owned
approximately 63% of the Company's shares at December 31, 1996.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1996 AND 1995




NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

EQUIPMENT:

Equipment is stated at cost.   Depreciation is incorporated on a straight line
basis over  a period of 5 to 7 years.  Expenditures for maintenance and repairs
are charged to expenses as incurred.  Upon retirement or disposal of assets,
the cost and accumulated depreciation are eliminated from the account and any
resulting gain or loss is included in expense.  See Note 3.

USE OF ESTIMATES:

In order to prepare financial statements in conformity with generally accepted
accounting principals,  management must make estimates and assumptions that
affect certain reported accounts and disclosures.  Actual results could differ
from these estimates.

INTELLECTUAL PROPERTIES:

The costs of intellectual properties are amortized using the straight-line
method over  a period of  fifteen years.  See Note 4.

EARNINGS PER SHARE:

The earnings per share calculation is based on the weighted average number of
shares outstanding during the period: 9,022,404  shares in 1996 and 2,333,839
shares in 1995.

INCOME TAX:

Because of losses sustained since inception, no provision has been made for
income tax.

NOTE 3 - EQUIPMENT AND LEASEHOLD IMPROVEMENTS

Equipment and building improvements at December 31, 1996 and 1995, consist of
the following:

The Company relocated to Reno, Nevada, during December, 1996.  By relocating,
the Company reduced its need for  certain equipment and leasehold improvements.
The Company does not own manufacturing equipment for its product.  The product
has been and will continue to be manufactured by third-party manufacturers
according to the Company's specifications.

NOTE 4 - INTELLECTUAL PROPERTIES

On January 7, 1994, the Company exchanged 2,856,000 shares with BTI  for the
intellectual rights to patent, develop, manufacture, and market PGE-1.   The
Company recorded the transfer of intellectual properties at the par value of
stock transferred, which amounted to $2,856.   BTI's largest shareholder, the
originator of PGE-1 holds a 2% royalty interest in the Company's gross
proceeds.

On November 16, 1995, the Company exchanged 6,138,500 shares of common stock
with BTI for assistance in raising working capital, patent application.,
management assistance and distribution agreements associated with the PGE-1
product.  The Company recorded the transfer  at the par value of stock
transferred, which amounted to $6,139.

During 1996, the Company expensed the unamortized cost of acquiring technology
relating to the development of an HIV home test kit.  The Company, which
originally acquired the rights in exchange for 335,000 shares of common stock,
ceased product development in connection with a settlement accrued in 1995
(Note 10).

NOTE 5 - ACCRUED EXPENSES

Accrued expenses at December 31, 1996 and 1995, consist of the following:

NOTE 6 - NOTES PAYABLE (CONTINUED)

See also Notes 9 and 10.

NOTE 7 - RELATED PARTY TRANSACTIONS

During 1994, the Company paid $150,000, to related parties for work performed
in completing  a merger (described in Note 1). Of this amount, $100,000 was
paid to BTI. The remaining $50,000 was paid to individuals affiliated with BTI.
These amounts have been  capitalized and are included in organizational costs.

Additional organizational costs of $24,625 were capitalized in 1994.  The
Company transferred  246,000 shares to its former owners and directors in
return for corporation property rights and 148,000 shares to individuals for
assistance in acquiring the rights.  These shares were valued at $.0625 per
share as determined by a 1994 appraisal.

During 1994 and 1995, the Company entered into three significant transactions
with related parties for the acquisition of intellectual rights and the
provision of  technological, management, fundraising, and marketing assistance.
Note 4 describes the valuation of these transactions.

The Company has a payable to BTI of  $183,535 and $130,000 as of December 31,
1996 and 1995, respectively.  The payable is related to costs incurred by BTI
on the Company's behalf for consultation and rent, as well as  research and
development of the PGE-1 product.

The Company has a note payable to a former director as of December 31, 1996 and
1995 (Note 6).  The amount of accrued interest associated with the note at
year-end in 1996 and 1995 was $6,419 and $8,097, respectively.

The Company often pays for services, fees, and salaries by issuing stock.  Most
of this stock is issued with a two-year selling restriction.  After the Company
files its registration statement in 1997, the two-year restriction may be
lifted.  The shares are valued at a  discount of free-trading stock, if market
valuation is available.   Several material transactions of this type occurred
during 1995 and 1996 during which time the Company issued 1,188,754 shares
recorded at $841,432.

See also the discussions regarding agreements, intellectual properties, and
subsequent events in Notes 4,  9, and 12.

NOTE 8 - INCOME TAXES

The Company has federal net operating loss carryforwards for financial
statement purposes of approximately $3,200,000 at December 31, 1996, which will
be used to offset future earnings of the Company.  The loss carryforwards will
expire during the years ending 2002 through 2012 if not used.

NOTE 9 - AGREEMENTS

In conjunction with the agreement of November 16, 1995, between BTI and the
Company (Note 4),  BTI transferred four agreements to the Company related to
the manufacture, marketing, and distribution of the PGE-1 product overseas.
The Company terminated two of these agreements during 1996 for nonperformance.
A third agreement for distribution in Korea was terminated in 1996 by mutual
agreement.  The Company is prepared to terminate a  fourth agreement with  its
European licensor, Pharma Maehle unless Pharma Maehle can resolve the Company's
concerns (Note 10).

In December 1996, the Company entered into an agreement with Martin E. Janis &
Company, Inc.  The agency will create and carry out a financial public
relations program in exchange for costs and an option on 50,000 shares of
free-trading stock, exercisable at $1.25 a share.

NOTE 10 - CONTINGENCIES

The Company has been named as a party in certain pending or threatened legal,
governmental, administrative, or judicial proceedings that arose in the
ordinary course of  business.  These pending or threatened proceedings may
affect the Company in a material way.

These financial statements reflect the way in which the Company resolved two
lawsuits:

    a.   The Company reached a mutual release regarding a Distribution
         Agreement which provided for the manufacture, marketing, and
         distribution of  HIV test kits.  The mutual release called for a
         $50,000 payment which  accrued during 1995 and  was paid in full
         during the first quarter of 1996.

    b.   The Company amicably settled an action with Thomas E. Waite &
         Associates regarding the a contract  under which Waite was to provide
         an array of business services.  The Company issued 568,750 shares of
         stock in settlement which was accrued in these financial statements at
         $494,813.

The ultimate effect of other  proceedings cannot be estimated at this time.
The Company has noted some possible irregularities pertaining to the June 1996
issuance of its convertible debentures and has taken steps to rectify the
matter. The Company hopes to resolve  two pending claims related to the
debenture issuance which aim to force a stock conversion. These claims were
filed after December 31, 1996, and are discussed in Note 12 as subsequent
events.

One additional act may impact the Company in the future although no
determination can be made at this time.  The Company is prepared to terminate
its licensing agreement with Pharma Maehle, the holder of the Company's
distribution rights in a portion of its overseas market.  The Company is
negotiating to resolve the contract issues to benefit business operations, but
the ultimate resolution and its impact upon the Company cannot be estimated.

                           DECEMBER 31, 1996 AND 1995




NOTE 10 - CONTINGENCIES  (CONTINUED)

The Company experienced a management change in December 1996 as it moved its
headquarters to Reno, Nevada.  The Company expects no negative impact from the
change.

NOTE 11 - UNCERTAINTY - GOING CONCERN

The financial statements of the company have been prepared assuming that the
Company will continue as a going concern.  The Company's continued existence is
dependent upon its ability to resolve its liquidity problems, principally by
obtaining additional equity capital and through the sale of the PGE-1 product.
If additional capital is not secured, then there is substantial doubt about the
Company's ability to continue as a going concern.  See also Note 12 regarding
the Company's plans to issue 6% Convertible Debentures in 1997.

NOTE 12 - SUBSEQUENT EVENTS

In February 1997, the Company became a defendant in a U.S. District Court
action  initiated by Ailouros Ltd.  Ailouros claims it is entitled to 263,225
shares of common stock and/or damages in the amount of $2,000,000.   The
Company had previously initiated a lawsuit in the Nevada courts respecting the
same claim and both matters were removed to Federal court.  The Company is
asking that any shares issued to Ailouros be issued pursuant to the
requirements of the SEC's Regulation S.  It is too early to estimate the
monetary outcome of this litigation.

In February 1997, the Company filed an action for damages due to negligence and
breach of contract by D. Weckstein and Co. Inc. and Donald Weckstein.  The
contract at issue was an agreement to obtain financing in exchange for Company
stock.  The Weckstein defendants subsequently filed a lawsuit in New York
against the Company respecting the same contract and asked for  damages against
a third party for  tortious interference with the contract.  The Weckstein
plaintiffs seek damages on their contract claim in the amount of $250,000 and
$400,000, and damages in excess of $10,000 on an abuse of process claim.  It is
too early to estimate the monetary outcome of this litigation.

The Company is preparing to issue $15,000,000 worth of  6% Convertible
Debentures.  If issued as planned, the Debentures will be convertible into
shares of common stock at  the lesser of the market price on March 21, 1997, or
80% of the market price on the conversion date.

During 1997, the Company authorized a transfer of  1,250,000 shares of common
stock to related parties in exchange for services previously rendered.

As discussed in Note 3, the Company moved its headquarters to Reno, Nevada, in
early 1997.  The Company still shares research and development facilities with
BTI in Irvine, California.

                PART II - INFORMATION NOT REQUIRED IN PROSPECTUS

              ITEM 24.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Nevada General Corporation Law (Nevada Revised Statutes, Chapter 78;
the "NGCL") permits a corporation organized thereunder to indemnify its
directors and officers for certain of their acts.  Article       of the
Company's Certificate of Incorporation provides that the Company shall, to the
full extent permitted by GCL, indemnify all persons whom may be indemnified
pursuant thereto.

     Section 78.751 of the NGCL provides generally that a corporation may
indemnify any person who was or is threatened to be made a named defendant or
respondent to any threatened, pending or completed action, suit or proceeding
by reason of the fact that he was or is a director, officer, employee or agent
of the Corporation, against expenses (which expenses, including attorney's
fees, may be advanced by the corporation when authorized under certain
circumstances), reasonably incurred by him in connection with such action, suit
or proceeding if he acted in good faith and in a manner he reasonably believed
to be in or not opposed to the best interests of the corporation or, with
respect to a criminal action, he had no reasonable cause to believe his conduct
was unlawful.  In a suit, action or proceeding against such person brought by
or on behalf of the corporation in which such person was found, after
exhaustion of all appeals, to be liable to the corporation, any indemnification
must be approved by the court in which such action is brought.  In addition,
unless limited by the articles of incorporation, should a director be
successful on the merits, Section 78.751 provides that he shall be indemnified
against expenses incurred by him.

     Section 78.752 of the NGCL empowers corporations to purchase and maintain
insurance on behalf of a director, officer, employee or agent of the
corporation against any liability, regardless of whether the corporation could
indemnify such person against such liabilities.

     INSOFAR AS INDEMNIFICATION FOR LIABILITIES ARISING UNDER THE SECURITIES
ACT OF 1933 MAY BE PERMITTED TO DIRECTORS, OFFICERS OR PERSONS CONTROLLING THE
COMPANY PURSUANT TO THE ABOVE, THE COMPANY HAS BEEN INFORMED THAT IN THE
OPINION OF THE SECURITIES AND EXCHANGE COMMISSION SUCH INDEMNIFICATION IS
AGAINST PUBLIC POLICY AS EXPRESSED IN THE ACT AND IS THEREFORE UNENFORCEABLE.



             ITEM 25.  OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION

     The following table sets forth an itemized list of all expenses to be
borne by the Registrant in connection with the issuance and distribution of the
securities being registered hereby other than underwriting discounts and

               ITEM 26.  RECENT SALES OF UNREGISTERED SECURITIES

     During 1994, the Company paid $150,000 to related parties for work
performed in completing a merger between Careyward, Inc. (as the Company was
then known) and Grant City Corporation ("GCC"), which was effected in 1993.  Of
this amount, $100,000 was paid to BTI and the remaining $50,000 was paid to
individuals affiliated with BTI.  The Company also transferred 246,000 shares,
as described below, to former owners and directors of GCC in return for GCC's
property rights and 148,000 shares to individuals in acquiring these rights.

     The Company had issued shares to various individuals and businesses in
lieu of cash payment for salaries, fees and services.  These include rent for
office space, consultancy services, scientific and technical advice,
directors' fees, and legal services.  During 1995 and 1996 alone, 1,188,754
shares were issued in such transactions.  Most of the stock issued for such
services carries a two-year selling restriction.  See "Recent Sales of
Unregistered Securities".  The Company anticipates that it will continue the
practice of issuing shares of Common Stock in lieu of cash payment in the
future.

     On February 2, 1994, the Company issued a total of 3,840,000 shares in
connection with the assignment of intellectual property to the Company and for
services rendered by consultants and former owners and directors of the
Company.  Of this amount, 2,856,000 shares were issued to BTI in consideration
of the assignment of the intellectual property rights to patent, develop,
manufacture and market PGE-1.  The remaining shares were issued to consultants
and former owners and directors of the Company in return for services they
rendered.  Of this amount, 492,000 shares were returned to treasury in July of
1994 as a result of the non-performance of services by the individuals who had
originally received the shares.  All of the shares listed in this paragraph
were issued in reliance upon the exemption provided by Section 4(2) of the
Securities Act of 1933, as amended.  All of these shares were also subject to

*    Incorporated by reference from the Registrant's Annual Report on Form
     10-SB filed on April 30, 1996.                                          



                             ITEM 28.  UNDERTAKINGS

     Insofar as indemnification for liabilities arising under the Securities
Act of 1933,  (the "Securities Act") may be permitted to directors, officers
and controlling persons of the Registrant pursuant to any of the provisions
described above, or otherwise, the Registrant has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other
than the payment by Registrant of expenses incurred or paid by a director,
officer, or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling persons in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act and will governed by the final adjudication of
such issue.

      The Registrant hereby undertakes that it will:

      (1)  File, during any period in which it offers or sells
           securities, a post-effective amendment to this registration
           statement to:

            (a)  include any prospectus required by Section 10(a)
                 of the Securities Act;

            (b)  reflect in the prospectus any facts or events
                 which, individually or in the aggregate, represent a
                 fundamental change in the information set forth in the
                 registration statement; and, notwithstanding the foregoing,
                 any increase or decrease in volume of securities offered (if
                 the total dollar value of securities offered would not exceed
                 that which was registered) and any deviation from the low or
                 high end of the estimated maximum offering range may be
                 reflected in the form of prospectus filed with the Commission
                 pursuant to Rule 424(b) if, in the aggregate, the changes in
                 the volume and price represent no more than a 20% change in
                 the maximum aggregate offering price set forth in the
                 "Calculation of Registration Fee" table in the effective
                 registration statement; and

            (c)  include additional or changed material
                 information with respect to the plan of distribution.

      (2)  For determining any liability under the Securities Act, treat
           each post-effective amendment as a new registration statement of the
           securities offered, and the offering of the securities at that time
           to be the initial bonafide offering; and

      (3)  File a post-effective amendment to remove from registration
           any of the securities that remain unsold at the termination of the
           offering.

      The  Registrant hereby further undertakes that it will:

      (1)  For determining any liability under the Securities Act, treat
           the information omitted from the form of prospectus filed as part of
           this Registration Statement in reliance upon Rule 430A and contained
           in a form of prospectus filed by the registrant pursuant to Rule
           424(b)(1) or (4) or 497(h) under the


                                      II-6

           Securities Act as part of this Registration Statement as of the time
           the Commission declared it effective; and

      (2)  For determining any liability under the Securities Act, treat
           each post-effective amendment that contains a form of prospectus as
           a new registration statement for the securities offered in the
           Registration Statement, and the offering of such securities at that
           time as the initial bona fide offering of those securities.

Harvard Scientific Corp.
100 No. Arlington, Suite 23P
Reno, NV 89501

Gentlemen:

         I have acted as General Counsel on behalf of Harvard Scientific Corp.
("Harvard"), a Nevada corporation, in connection with the 6% Convertible
Debentures (the "Debentures"), which are the subject of the Securities Purchase
Agreement dated March 21, 1997 to which Harvard is a party.

         Pursuant to the terms of the Securities Purchase Agreement, Harvard
will issue Convertible Debentures in denominations of $100,000.00 which bear
interest at the rate of 6% per annum and mature on March 30, 1998 as to the
first tranche of $5,000,000.00 worth of Debentures already issued and will
mature as of the end of the first anniversary month of issuance of the two (2)
additional $5,000,000.00 tranches contemplated under the Securities Purchase
Agreement.  Upon the maturity of the Debentures, payment for principal and
accrued interest will be made either in currency or in shares of Harvard's
stock, at the option of the holder.

         The holder may convert the Debentures into shares of Harvard's common
stock commencing on the effective date of a Registration Statement for such
shares.  The conversion price per share will be either (a) $6.525, the market
price as defined in the Debentures as of March 21, 1997, or (b) 80% of the
market price on the date of conversion, whichever is lower.  "Market Price", as
used in connection with the Debentures, means the average closing bid price of
the common stock of Harvard on the five (5) trading days immediately preceding
March 21, 1997 or the conversion date as may be applicable, as reported by the
National Association of
<PAGE>   2
Harvard Scientific Corp.

Securities Dealers, or the closing bid price on the over-the-counter market on
such date, or in the event the common stock is listed on a stock exchange or
traded on NASDAQ, the "Market Price" means the closing price on the exchange on
such date, as reported in the Wall Street Journal.  Harvard has the option of
paying the interest accrued from the date of issuance to the date of conversion
either in cash or in shares of common stock.

         Pursuant to the terms of the Securities Purchase Agreement and the
Debentures, Harvard may redeem the Debentures for which a Notice of Conversion
has not been submitted if the conversion price equals or is less than $1.60 per
share by delivering a Notice of Redemption to the holder.  However, the holder
may still opt to convert any such Debentures into shares of common stock by
submitting a Notice of Conversion to Harvard within three (3) business days of
the holder's receipt of the company's Notice of Redemption.

         Also pursuant to the terms of the Securities Purchase Agreement and
the Debentures, the redemption price will be 125% of the principal amount of
the Debentures, plus accrued unpaid interest.  Harvard must pay a redemption
price to the holder within ten (10) days from the date of the Notice of
Redemption.  If Harvard fails to make the redemption payment within the ten
(10) day period, the company forfeits the right to redeem those Debentures.

         Pursuant to the terms of the Securities Purchase Agreement and the
Debentures, a holder may also require Harvard to declare whether it intends to
effect a redemption within the following ten (10) days by faxing a notice to
the company.  Harvard must respond to this notice within 24 hours.  If it fails
to do so, Harvard may not redeem the holder's Debentures during the ten (10)
day period commencing 24 hours after the date of the notice from the holder.

         Pursuant to the terms of the Securities Purchase Agreement and

the Debentures, if Harvard merges or consolidates with another corporation, or
sells or transfers all or substantially all of its assets to another person
and, as a condition of such merger, consolidation or sale, the holders of the
company's common stock are entitled to receive stock or securities in another
corporation or to receive property in exchange for the company's common stock,
then the Debenture may be converted into the kind and amount of stock,
securities or property receivable by the holders of the Harvard's common stock
pursuant to the transaction.  If, within fifteen (15) days of the holder's
receipt of a notice from the company advising of a proposed merger,
consolidation or sale, the holder has not submitted a Notice of Conversion,
then Harvard may prepay all outstanding principal and accrued interest and
thereby terminate the holder's conversion rights.

         As General Counsel for the corporation in this regard, I have reviewed
the various corporate proceedings taken by Harvard in connection with the
authorization and issuance of the Debentures and the authorization and
reservation for issuance of the shares of common stock issuable in connection
with the Debentures, and I have examined originals, or copies certified to my
satisfaction, of such corporate records of Harvard and other instruments and
documents as I have deemed necessary as the basis for the opinions hereinafter
expressed.

         On the basis of the foregoing, I am of the opinion that the Debentures
have been duly and validly authorized by Harvard and that the shares of common
stock which may be issued in connection with the Debentures will be legally and
validly issued: (1) upon the effectiveness of the company's Registration
Statement for such shares on Form SB-2; and, (2) the completion of all
requirements or contingencies contained in the Securities Purchase Agreement
and the Debentures for the conversion of such Debentures into the shares of
common stock of Harvard.

strictest confidence and shall not (other than as specifically allowed in
writing by Harvard) disclose or use any trade secret or confidential
information of Harvard, directly or indirectly, or use them in any way, either
during the term of the Consultant's engagement, or at any time thereafter,

                                       4

<PAGE>   5



trade secret or confidential information means all information concerning
Harvard, clients of Harvard, or any parent, subsidiary or affiliate of Harvard
or a client, any supplier, or any client (including, but not limited to,
information regarding the peculiarities, preferences and manner of doing
business) that is not generally known to the public. All items referred to in
this paragraph and similar items relating to business of Harvard or client,
whether prepared by Consultant or otherwise, shall remain the exclusive
property of Harvard or client and shall not be removed otherwise, shall remain
the exclusive property of Harvard or client, and shall not be removed from

appropriate injunctive relief from an appropriate court or arbitrator, at its
election, without bond, including mandatory injunction.

                                       5

<PAGE>   6

desirable for obtaining, sustaining, reusing or enforcing Letters Patent in the
United States and throughout the world for said inventions, and for perfecting,
recording or maintaining the title of Harvard, its successors and assigns, to
said Inventions and to any patent applications made and any Letters Patent
granted for said inventions in the United States and throughout the world.

            6.3   RECORDS, OBLIGATION TO KEEP.  Consultant will keep complete,
accurate and authentic accounts, notes, data and records of any and all kinds
of said inventions in the manner and form requested by Harvard. Such accounts,

accounts, notes, data, sketches, drawings and other documents and records, and
all material and physical items of any kind, including all reproductions and
copies thereof, which relate in any way to the business, products, practices or
techniques of Harvard or contain confidential information, made by Consultant
or that come into his possession by reason of his engagement are the property
of Harvard at the conclusion of this Consulting Agreement.

         7. DISPUTE RESOLUTION PROCEDURE. Any controversy or claim, including,
but not limited to tort and contract claims, arising out of, or relating to
Consultant's engagement, the termination of


                                       6

<PAGE>   7


Consultant's employment, commissions, the terms and conditions of this
Consulting Agreement, or the coverage of this dispute resolution procedure
shall be resolved by binding arbitration in accordance with the Commercial
Rules them obtaining of the American Arbitration Association Judgment upon the
arbitrator's award may be entered by any court of competent jurisdiction and
may include reasonable attorneys fees in the discretion of the arbitrator.

         8. INJUNCTIVE RELIEF. The services of Consultant, as well as the trade
secrets and the proprietary and confidential information of Harvard are of a
special, unique, unusual and extraordinary nature, which gives them a peculiar
value, the loss of which cannot reasonably or adequately be compensated for in
damages in an action at law. The breach by either party of any provision of
this Consulting Agreement would cause the other party irreparable injury and
damage, the measure of which could not be adequately measured at law.
Accordingly, each party shall be entitled, as a matter of right, to injunctive
and other equitable relief to prevent the violation of any provision of this
Consulting Agreement by the other. Each party hereby consents to the granting
of such injunctive or other equitable relief provided notice is given
hereunder. The exercise by either party of its rights hereunder shall not
constitute a waiver by such party of any other rights which it may have to
damages or otherwise.

         9. CONSENT TO JURISDICTION. All legal proceedings in connection with
this Consulting Agreement shall be undertaken 


                                       7

<PAGE>   8

before an arbitrator pursuant to paragraph 7, except that claims for injunctive
or other equitable relief, or extraordinary writs may be brought in a proper
court in the State of Nevada, County of Washoe. Election by any party to this
Agreement to seek such relief in court shall not constitute a waiver of
arbitration pursuant to paragraph 7, but shall be used to preserve the status
quo pending arbitration. Both parties consent to the jurisdiction of any
arbitrator or court, state or federal, in the State of Nevada, provided notice
is given as provided in paragraph 10 below, of the commencement of such action.


        10. NOTICE. Any notices hereunder shall be in writing and shall be

States mail, registered or certified, return receipt requested, postage

to preserve the status quo pending arbitration. Both parties consent to the

Nevada, provided notice is given as provided in paragraph 10 below, of the

                NOW THEREFORE, in consideration of the premises and the mutual
covenants contained herein and other good and valuable consideration, the

                1.      AGREEMENT TO PURCHASE; PURCHASE PRICE.

                a.      PURCHASE.  The undersigned hereby agrees to purchase

                2.  BUYER REPRESENTATIONS, WARRANTIES, ETC.; ACCESS TO
INFORMATION; INDEPENDENT INVESTIGATION.

                The Buyer represents and warrants to, and covenants and agrees
with, the Company as follows:

                a.      Without limiting Buyer's right to sell the Common Stock
pursuant to the Registration Statement, the Buyer is purchasing the Debenture
and will be acquiring the shares of Common Stock issuable upon conversion of
the Debenture for its own account for investment only and not with a view
towards the public sale or distribution thereof and not with a view to or for
sale in connection with any distribution thereof;

                b.      The Buyer is (i) an "accredited investor" as that term
is defined in Rule 501 of the General Rules and Regulations under the 1933 Act
by reason of Rule 501(a)(3), and (ii) experienced in making investments of the
kind described in this Agreement and the related documents, (iii) able, by
reason of the business and financial experience of its officers (if an entity)
and professional advisors (who are not affiliated with or compensated in any
way by the Company or any of its affiliates or selling agents), to protect its
own interests in connection with the transactions described in this Agreement,
and the related documents, and (iv) able to afford the entire loss of its
investment in the Securities;

                c.      All subsequent offers and sales of the Debenture and
the shares of Common Stock issuable upon conversion of, or issued as dividends
on, the Debenture (the "Shares" and, 


                                      2
<PAGE>   3


together with the Debenture, the "Securities") by the Buyer shall be made
pursuant to registration of the Shares under the 1933 Act or with respect to
the Debenture pursuant to an exemption from registration;

                d.      The Buyer understands that the Debenture is being
offered and sold, and the Shares are being offered, to it in reliance on
specific exemptions from the registration requirements of United States federal
and state securities laws and that the Company is relying upon the truth and
accuracy of, and the Buyer's compliance with, the representations, warranties,
agreements, acknowledgements and understandings of the Buyer set forth herein
in order to determine the availability of such exemptions and the eligibility
of the Buyer to acquire the Debenture and to receive an offer of the Shares;

                e.      The Buyer and its advisors, if any, have been furnished
with all materials relating to the business, finances and operations of the
Company and materials relating to the offer and sale of the Debenture and the
offer of the Shares which have been requested by the Buyer, including ANNEX V
hereto. The Buyer and its advisors, if any, have been afforded the opportunity
to ask questions of the Company and have received complete and satisfactory
answers to any such inquiries.  Without limiting the generality of the
foregoing, the Buyer has also had the opportunity to obtain and to review the
Company's (1) a draft of the Annual Report on Form 10-KSB for the fiscal year
ended December 31, 1996, (2) Quarterly Report on Form 10-QSB for the fiscal
quarter ended September 30, 1996, and (3) Form 10-SB (the "Company's SEC
Documents").

                f.      The Buyer understands that its investment in the
Securities involves a high degree of risk;

                g.      The Buyer understands that no United States federal or
state agency or any other government or governmental agency has passed on or
made any recommendation or endorsement of the Securities;

                h.      This Agreement has been duly and validly authorized,
executed and delivered on behalf of the Buyer and is a valid and binding
agreement of the Buyer enforceable in accordance with its terms, subject as to
enforceability to general principles of equity and to bankruptcy, insolvency,
moratorium and other similar laws affecting the enforcement of creditors'
rights generally.

                i.      Neither Buyer, nor any affiliate of Buyer, has any
present intention of entering into, any put option, short position, or other
similar position with respect to the Debenture or the Shares.

                j.      Notwithstanding the provisions hereof or of the
Debenture, in no event (except with respect to an Event of Mandatory Conversion
upon the maturity of the Debenture) shall the holder be entitled to convert any
Debenture to the extent after such conversion, the sum of (1) the number of
shares of Common Stock beneficially owned by the Buyer and its affiliates
(other than shares of Common Stock which may be deemed beneficially owned
through the ownership of the 


                                      3
<PAGE>   4


unconverted portion of the Debenture), and (2) the number of shares of Common
Stock issuable upon the conversion of the Debenture with respect to which the
determination of this proviso is being made, would result in beneficial
ownership by the Buyer and its affiliates of more than 4.9% of the outstanding
shares of Common Stock.  For purposes  of the proviso to the immediately
preceding sentence, beneficial ownership shall be determined in accordance with
Section 13(d) of the Securities Exchange Act of 1934, as amended, and
Regulation 13 D-G thereunder, except as otherwise provided in clause (1) of
such proviso.

                3.      COMPANY REPRESENTATIONS, ETC.

                The Company represents and warrants to the Buyer that:

                a.      CONCERNING THE SHARES.   There are no preemptive rights
of any stockholder of the Company, as such, to acquire the Common Shares.  

                b.      REPORTING COMPANY STATUS.  The Company is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Nevada.  The Company has registered its Common Stock pursuant to
Section 12 of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), and the Common Stock is listed and traded on the NASDAQ/Bulletin Board. 
The Company has received no notice, either oral or written, with respect to the
continued eligibility of the Common Stock for such listing.

                c.      AUTHORIZED SHARES.  The Company has sufficient
authorized and unissued Shares as may be reasonably necessary to effect the
conversion of the Debenture.  The Common Shares have been duly authorized and,
when issued upon conversion of, or as interest on, the Debenture, will be duly
and validly issued, fully paid and non-assessable and will not subject the
holder thereof to personal liability by reason of being such holder.

                d.      SECURITIES PURCHASE AGREEMENT; REGISTRATION RIGHTS
AGREEMENT AND STOCK.  This Agreement and the Registration Rights Agreement, the
form of which is attached hereto as ANNEX IV (the "Registration Rights
Agreement"), and the transactions contemplated thereby, have been duly and
validly authorized by the Company, this Agreement has been duly executed and
delivered by the Company and this Agreement is, and the Registration Rights
Agreement, when executed and delivered by the Company, will be, valid and
binding agreements of the Company enforceable in accordance with their
respective terms, subject as to enforceability to general principles of equity
and to bankruptcy, insolvency, moratorium, and other similar laws affecting the
enforcement of creditors' rights generally; and the Debenture will be duly and
validly authorized and, when executed and delivered on behalf of the Company in
accordance with this Agreement, will be a valid and binding obligation of the
Company in accordance with its terms, subject to general principles of equity
and to bankruptcy, insolvency, moratorium, or other similar laws affecting the
enforcement of creditors' rights generally.

                e.      NON-CONTRAVENTION.  The execution and delivery of this
Agreement and the Registration Rights Agreement by the Company, the issuance of
the Securities, and the

consummation by the Company of the other transactions contemplated by this
Agreement, the Registration Rights Agreement, and the Debenture do not and will
not conflict with or result in a breach by the Company of any of the terms or
provisions of, or constitute a default under (i) the articles of incorporation
or by-laws of the Company, (ii) any indenture, mortgage, deed of trust, or
other material agreement or instrument to which the Company is a party or by
which it or any of its properties or assets are bound, including any listing
agreement for the Common Stock, (iii) any existing applicable law, rule, or
regulation or any applicable decree, judgment, or (iv) order of any court,
United States federal or state regulatory body, administrative agency, or other
governmental body having jurisdiction over the Company or any of its properties
or assets, except such conflict, breach or default which would not have a
material adverse effect on the transactions contemplated herein.

                f.      APPROVALS.  No authorization, approval or consent of
any court, governmental body, regulatory agency, self-regulatory organization,
or stock exchange or market or the Stockholders of the Company is required to

Buyer as contemplated by this Agreement, except such authorizations, approvals
and consents that have been obtained.

                g.      SEC FILINGS.  None of the SEC Filings with the
Securities and Exchange Commission since the filing of the 10-QSB on September
30, 1996 contained, at the time they were filed, any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements made therein in light of the circumstances
under which they were made, not misleading.  Except as set forth on Annex V
hereto, the Company has since September 30, 1996 timely filed all requisite
forms, reports and exhibits thereto with the Securities and Exchange
Commission.

                h.      ABSENCE OF CERTAIN CHANGES.  Since September 30, 1996,
there has been no material adverse change and no material adverse development
in the business, properties, operations, financial condition, or results of
operations of the Company, except as disclosed in the documents referred to in
Section 2(e) hereof.

                i.      FULL DISCLOSURE.  There is no fact known to the Company
(other than general economic conditions known to the public generally) that has
not been disclosed in writing to the Buyer that (i) could reasonably be
expected to have a material adverse effect on the condition (financial or
otherwise) or in the earnings, business affairs, properties or assets of the
Company or (ii) could reasonably be expected to materially and adversely affect
the ability of the Company to perform its obligations pursuant to this
Agreement.

                j.      ABSENCE OF LITIGATION.  Except as set forth in ANNEX V
hereto, and in the draft of the Form 10-QSB, which the Buyer has reviewed,
there is no action, suit, proceeding, inquiry or investigation before or by any
court, public board or body pending or, to the knowledge of the Company or any
of its subsidiaries, threatened against or affecting the Company or any of its
subsidiaries, wherein an unfavorable decision, ruling or finding would have a
material adverse effect on the properties, business, condition (financial or
other), results of operations or prospects of the 


                                      5
<PAGE>   6


Company and its subsidiaries taken as a whole or the transactions contemplated
by this Agreement or any of the documents contemplated hereby or which would
adversely affect the validity or enforceability of, or the authority or ability
of the Company to perform its obligations under, this Agreement or any of such
other documents.

                k.      ABSENCE OF EVENTS OF DEFAULT.  Except as set forth in
ANNEX V hereto, no Event of Default, as defined in the respective agreement to
which the Company is a party, and no event which, with the giving of notice or
the passage of time or both, would become an Event of Default (as so defined),
has occurred and is continuing, which would have a material adverse effect on
the Company's financial condition or results of operations.

                l.      NO DEFAULT.  The Company is not in default in the
performance or observance of any material obligation, agreement, covenant or
condition contained in any indenture, mortgage, deed of trust or other material
instrument or agreement to which it is a party or by which it or its property
is bound, and neither the execution, nor the delivery by the Company, nor the
performance by the Company of its obligations under this Agreement or the
Debenture, other than the conversion provision thereof, will conflict with or
result in the breach or violation of any of the terms or provisions of, or
constitute a default or result in the creation or imposition of any lien or
charge on any assets or properties of the Company under, any material
indenture, mortgage, deed of trust or other material agreement applicable to
the Company or instrument to which the Company is a party or by which it is
bound or any statute or the Certificate of Incorporation or By-Laws of the
Company, or any decree, judgment, order, rule or regulation of any court or
governmental agency or body having jurisdiction over the Company or its
properties, or the Company's listing agreement for its Common Stock.

                 m.    PRIOR ISSUES.  During the twelve (12) months preceding
the date hereof, the Company has not issued any securities except as set forth
in Exhibit 3(m).  The presently outstanding unconverted principal amount of
each such issuance as at March 20, 1997  are set forth in Exhibit 3(m).

                4.      CERTAIN COVENANTS AND ACKNOWLEDGMENTS.

                a.      TRANSFER RESTRICTIONS.  The Buyer acknowledges that (1)
the Debenture has not been and is not being registered under the provisions of
the 1933 Act and, except as provided in the Registration Rights Agreement, the
Shares have not been and are not being registered under the 1933 Act, and may
not be transferred unless (A) subsequently registered thereunder or (B) the
Buyer shall have delivered to the Company an opinion of counsel, reasonably
satisfactory in form, scope and substance to the Company, to the effect that
the Securities to be sold or transferred may be sold or transferred pursuant to
an exemption from such registration; (2) any sale of the Securities made in
reliance on Rule 144 promulgated under the 1933 Act may be made only in
accordance with the terms of said Rule and further, if said Rule is not
applicable, any resale of such Securities under circumstances in which the
seller, or the person through whom the sale is made, may be deemed to be an
underwriter, as that term is used in the 1933 Act, may require compliance with
some other exemption under the 1933 Act or 



                                      6
<PAGE>   7

the rules and regulations of the SEC thereunder; and (3) neither the Company
nor any other person is under any obligation to register the Securities (other
than pursuant to the Registration Rights Agreement) under the 1933 Act or    
to comply with the terms and conditions of any exemption thereunder.       

                b.      RESTRICTIVE LEGEND.  The Buyer acknowledges and agrees
that the Debentures, and, until such time as the Common Stock has been
registered under the 1933 Act as contemplated by the Registration Rights
Agreement and sold in accordance with such Registration Statement, the shares
of Common Stock issued to the Holder upon conversion of the Debentures shall
bear a restrictive legend in substantially the following form (and a
stop-transfer order may be placed against transfer of the Debenture and such
shares of Common Stock):

                THESE SECURITIES (THE "SECURITIES")  HAVE NOT BEEN REGISTERED
                UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
                ACT"), OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD
                OR OFFERED FOR SALE IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
                STATEMENT FOR THE SECURITIES OR AN OPINION OF COUNSEL OR OTHER
                EVIDENCE ACCEPTABLE TO THE CORPORATION THAT SUCH REGISTRATION
                IS NOT REQUIRED.

                c.      REGISTRATION RIGHTS AGREEMENT.  The parties hereto
agree to enter into the Registration Rights Agreement, in substantially the
form attached hereto as ANNEX IV, on or before the Closing Date.
                    
                d.      FILINGS.  The Company undertakes and agrees to make all
necessary filings in connection with the sale of the Debenture to the Buyer
under any United States laws and regulations, or by any domestic securities
exchange or trading market, and to provide a copy thereof to the Buyer promptly
after such filing.

                e.      REPORTING STATUS.  So long as the Buyer beneficially
owns any of the Debentures, the Company shall file all reports required to be
filed with the SEC pursuant to Section 13 or 15(d) of the Securities Exchange
Act of 1934, as amended (the "1934 Act"), and the Company shall not terminate
its status as an issuer required to file reports under the 1934 Act even if the
1934 Act or the rules and regulations thereunder would permit such termination.

                f.      USE OF PROCEEDS.  The Company will use the proceeds
from the sale of the Debenture (excluding amounts paid by the Company for legal
fees and finder's fees in connection with the sale of the Debenture) for
internal working capital purposes and shall not, directly or indirectly, use
such proceeds for any loan to or investment in any other corporation,
partnership enterprise or other person, except its parent Biosphere Technology,
Inc.

                g.      CERTAIN AGREEMENTS.  The Company covenants and agrees
that it will not (i) 


                                      7

<PAGE>   8


enter into any subsequent or further offer or sale of common stock or
securities convertible into common stock with any third party until the
expiration of a period of one hundred eighty (180) days after the effective
date of the Registration Statement under the Registration Rights Agreement. 
However, clause g(i) will not apply to (i) the issuance of securities (other
than for cash) in connection with a merger, consolidation, sale of assets,
disposition of a business, product or license by the Company, strategic
alliance, public offering, securities issued at the then current market price,
in exercise of options, or (ii) the exchange of the capital stock of the
Company for assets, stock or other equity interests.

                h.      OPTION.  Notwithstanding Section 4(g), during the six
(6) month period following the Closing Date, the Buyer agrees to purchase up to
an additional $10,000,000 principal amount of Debentures (the "Additional
Debentures") in two tranches of $5,000,000 each, commencing not less than sixty
(60) days after the Effective Date, upon the same terms and conditions as those
applicable to the Debentures issued pursuant to this Agreement, (the
"Additional Closing Date").  Buyer's obligation to purchase the Additional
Debentures on the Additional Closing Date shall be contingent upon the
satisfaction of the following conditions:  On each the Additional Closing Date
(i) the Registration Statement required to be filed under the Registration
Rights Agreement is effective (the "Effective Date"), (ii) the representations
and warranties of the Company contained in Section 3 are true and correct in
all material respects, and (iii) the Market Price for the five trading days
prior to each Additional Closing Date exceeds $3.50.  Each such Debenture shall
mature on the last day of the twelfth month following its issuance.

                i.      PERMISSIVE REDEMPTION. [T/B/D]

                5.      TRANSFER AGENT INSTRUCTIONS.

                a.      Promptly following the delivery by the Buyer of the
aggregate purchase price for the Debenture in accordance with Section 1(c)
hereof, the Company will irrevocably instruct its transfer agent to issue
Common Stock from time to time upon conversion of the Debenture in such amounts
as specified from time to time by the Company to the transfer agent, bearing
the restrictive legend specified in Section 4(b) of this Agreement prior to
registration of the Shares under the 1933 Act, registered in the name of the
Buyer or its nominee and in such denominations to be specified by the Buyer in
connection with each conversion of the Debenture.  The Company warrants that no
instruction other than such instructions referred to in this Section 5 and stop
transfer instructions to give effect to Section 4(a) hereof prior to
registration and sale of the Shares under the 1933 Act will be given by the
Company to the transfer agent and that the Shares shall otherwise be freely
transferable on the books and records of the Company as and to the extent
provided in this Agreement, the Registration Rights Agreement, and applicable
law.  Nothing in this Section shall affect in any way the Buyer's obligations
and agreement to comply with all applicable securities laws upon resale of the
Securities.  If the Buyer provides the Company with an opinion of counsel
reasonably satisfactory to the Company that registration of a resale by the
Buyer of any of the Securities in accordance with clause (1)(B) of Section 4(a)
of this Agreement is not required under the 1933 Act, the Company shall (except
as provided in clause (2) of Section 4(a) of this Agreement) permit the
transfer of the Securities and, in the case of the Shares, promptly instruct
the Company's 


                                      8

transfer agent to issue one or more certificates for Common Stock without
legend in such name and in such denominations as specified by the Buyer.

                b.      The Company will permit the Buyer to exercise its right
to convert the Debenture by telecopying an executed and completed Notice of
Conversion to the Company with a copy to the Transfer Agent and delivering
within three business days thereafter, the original Notice of Conversion and
the Debenture representing the Shares to the Company by express courier to the
Transfer Agent.  Each date on which a Notice of Conversion is telecopied to and
received by the Company in accordance with the provisions hereof shall be
deemed a Conversion Date.  The Company will transmit the certificates
representing the Shares of Common Stock issuable upon conversion of any
Debenture (together with the Debenture representing the Shares not so
converted) to the Buyer via express courier, by electronic transfer or
otherwise, within three business days after receipt by the Company of the
original Notice of Conversion and the Debenture representing the Shares to be
converted (the "Delivery Date").  

                c.      The Company understands that a delay in the issuance of
the Shares of Common Stock beyond the Delivery Date could result in economic
loss to the Buyer.  As compensation to the Buyer for such loss, the Company
agrees to pay late payments to the Buyer for late issuance of Shares upon
Conversion in accordance with the following schedule (where "No. Business Days
Late" is defined as the number of business days beyond five (5) business days
from Delivery Date:

The Company shall pay any payments incurred under this Section in immediately
available funds upon demand.  Nothing herein shall limit Buyer's right to
pursue actual damages for the Company's failure to issue and delivery Common
Stock to the Buyer.  Furthermore, in addition to any other remedies which may
be available to the Buyer, in the event that the Company fails for any reason
to effect delivery of such shares of Common Stock within five business days
after the Delivery Date, 

                                      9

No. 1                                                           US $5,000,000

                         HARVARD SCIENTIFIC CORPORATION

                 6% CONVERTIBLE DEBENTURE DUE MARCH 30, 1998


        THIS DEBENTURE is one of a duly authorized issue of $15,000,000 in
Debentures of HARVARD SCIENTIFIC CORPORATION, a corporation duly organized and
existing under the laws of the State of Nevada (the "Company") designated as
its 6% Convertible Debenture Due [End Month] 1998.

        FOR VALUE RECEIVED, the Company promises to pay to Springrange
Investment Group, Ltd., the registered holder hereof (the "Holder"), the
principal sum of Five Milllion Dollars (US $5,000,000) on [End Month] 1998 (the
"Maturity Date") and to pay interest on the principal sum outstanding from time
to time in arrears upon conversion as provided herein on [End Month] 1998 at
the rate of 6% per annum accruing from the date of initial issuance.  Accrual
of interest shall commence on the first such business day to occur after the
date hereof until payment in full of the principal sum has been made or duly
provided for.  Subject to the provisions of  4 below, the principal of, and
interest on, this Debenture are payable at the option of the Holder, in shares

extent of the sum represented by such check plus any amounts so deducted.




<PAGE>   16
         This Debenture is subject to the following additional provisions:

         1.      The Debentures are issuable in denominations of One Hundred
Thousand Dollars (US$100,000) and integral multiples thereof.  The Debentures
are exchangeable for an equal aggregate principal amount of Debentures of
different authorized denominations, as requested by the Holders surrendering
the same.  No service charge will be made for such registration or transfer or
exchange.

         2.      The Company shall be entitled to withhold from all payments of
principal of, and interest on, this Debenture any amounts required to be
withheld under the applicable provisions of the United States income tax laws
or other applicable laws at the time of such payments, and Holder shall execute
and deliver all required documentation in connection therewith.

         3.      This Debenture has been issued subject to investment
representations of the original purchaser hereof and may be transferred or
exchanged only in compliance with the Securities Act of 1933, as amended (the
"Act"), and other applicable state and foreign securities laws.  In the event
of any proposed transfer of this Debenture, the Company may require, prior to
issuance of a new Debenture in the name of such other person, that it receive
reasonable transfer documentation including opinions that the issuance of the
Debenture in such other name does not and will not cause a violation of the Act
or any applicable state or foreign securities laws.   Prior to due presentment
for transfer of this Debenture, the Company and any agent of the Company may
treat the person in whose name this Debenture is duly registered on the
Company's Debenture Register as the owner hereof for the purpose of receiving
payment as herein provided and for all other purposes, whether or not this
Debenture be overdue, and neither the Company nor any such agent shall be
affected by notice to the contrary.

         4.      (a)   Subject to Section 4(b), the Holder of this Debenture is
entitled, at its option, to convert at any time (a) commencing the earlier of
(i) ninety (90) days after the closing of sale of the Debenture with respect to
one-half of the principal amount of this Debenture, (ii) one hundred twenty
(120) days after the closing of sale of the Debentures with respect to the
balance of the principal amount of this Debenture (the "Closing"), or (b) the
effective date of the Registration Statement filed pursuant to the Registration
Rights Agreement between the Company and the Holder, or the Holder's
predecessor in interest, the principal amount of this Debenture, provided that
the principal amount is at least US $10,000 (unless if at the time of such
election to convert the aggregate principal amount of all Debentures registered
to the Holder is less that Ten Thousand Dollars (US $10,000), then the whole
amount thereof) into shares of Common Stock of the Company at a conversion
price for each share of Common Stock equal to the lesser of (a) 100% of the
Market Price on March 21, 1997, or (b) 80% of the Market Price on the
Conversion Date.  For purposes of this Section 4, the Market Price shall be the
average closing bid price of the Common Stock on the five (5) trading days
immediately preceding March 21,






<PAGE>   17
1997 or Conversion Date, as may be applicable, as reported by the National
Association of Securities Dealers, or the closing bid price on the
over-the-counter market on such date or, in the event the Common Stock is
listed on a stock exchange or traded on NASDAQ, the Market Price shall be the
closing price on the exchange on such date, as reported in the Wall Street
Journal.  Conversion shall be effectuated by surrendering the Debentures to be
converted to the Company with the form of conversion notice attached hereto as
Exhibit A, executed by the Holder of the Debenture evidencing such Holder's
intention to convert this Debenture or a specified portion (as above provided)
hereof, and accompanied, if required by the Company, by proper assignment
hereof in blank.  Interest accrued or accruing from the date of issuance to the
date of conversion shall, at the option of the Company, be paid in cash or
Common Stock upon conversion.  No fraction of Shares or scrip representing
fractions of shares will be issued on conversion, but the number of shares
issuable shall be rounded to the nearest whole share.  The date on which notice
of conversion is given (the "Conversion Date") shall be deemed to be the date
on which the Holder has delivered this Debenture, with the conversion notice
duly executed, to the Company or, the date set forth in such facsimile delivery
of the notice of conversion if the Debenture is received by the Company within
three (3) business days therefrom.  Facsimile delivery of the conversion notice
shall be accepted by the Company at telephone number (702-322-5623; ATT: Don
Steffens).  Certificates representing Common Stock upon conversion will be
delivered within three (3) business days from the date the notice of conversion
is delivered to the Company.

         (b)     (i)      If such conversion price on the date of conversion
                          would be or is less than or equal to $1.60 per share,
                          the Company shall have the right to redeem any
                          Debentures for which a Notice of Conversion has not
                          theretofore been submitted by delivering a Notice of
                          Redemption to the Holder of the Debenture.

                 (ii)     The redemption price shall be calculated at 125% of
                          the principal amount of the Debenture, plus accrued
                          and unpaid interest, and shall be paid to the Holder
                          within ten (10) days from the date of the Notice of
                          Redemption.  Any such Notice of Redemption shall not
                          be effective, with respect to any Debentures for
                          which a Notice of Conversion is submitted to the
                          Company, within three (3) business days of the
                          Holder's receipt of the Company's Notice of
                          Redemption.  Furthermore, in the event such payment
                          is not timely made, any rights of the Company to
                          redeem the Debenture shall terminate, and the Notice
                          of Redemption shall be null and void.

                 (iii)    A Holder may also fax a notice to the Company, Attn:
                          Don Steffens, requiring the Company to declare by 
                          faxed notice within 24 hours of the Notice from the 
                          Holder, whether it intends to effect any redemption 
                          during the ten (10) business days following 24 hours
                          from the Holder's Notice.  In the event the Company 
                          does not reply during said 24 hour period, the 
                          Company may not redeem that Holder's Debentures 
                          during the ten (10) day period commencing 24 hours 
                          after the Notice from the Holder.

         5.      No provision of this Debenture shall alter or impair the
obligation of the Company, which is absolute and unconditional, to pay the
principal of, and interest on, this Debenture at the time, place, and rate, and
in the coin or currency, herein proscribed.  This Debenture and all other
Debentures now or hereafter issued of similar terms are direct obligations of
the Company.

         6.      No recourse shall be had for the payment of the principal of,
or the interest on, this Debenture, or for any claim based hereon, or otherwise
in respect hereof, against any incorporator, shareholder, officer or director,
as such, past, present or future, of the Company or any successor corporation,
whether by virtue of any constitution, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the issue
hereof, expressly waived and released.

         7.      If the Company merges or consolidates with another corporation
or sells or transfers all or substantially all of its assets to another person
and the holders of the Common Stock are entitled to receive stock, securities
or property in respect of or in exchange for Common Stock, then as a condition
of such merger, consolidation, sale or transfer, the Company and any such
successor, purchaser or transferee agree that the Debenture may thereafter be
converted on the terms and subject to the conditions set forth above into the
kind and amount of stock, securities or property receivable upon such merger,
consolidation, sale or transfer by a holder of the number of shares of Common
Stock into which this Debenture might have been converted immediately before
such merger, consolidation, sale or transfer, subject to adjustments which
shall be as nearly equivalent as may be practicable.  In the event of any
proposed merger, consolidation or sale or transfer of all or substantially all
of the assets of the Company (a "Sale"), the Holder hereof shall have the right
to convert by delivering a Notice of Conversion to the Company within fifteen
(15) days of receipt of notice of such Sale from the Company.  In the event the
Holder hereof shall elect not to convert, the Company may prepay all
outstanding principal and accrued interest on this Debenture, less all amounts
required by law to be deducted, upon which tender of payment following such
notice, the right of conversion shall terminate.

         8.      The Holder of the Debenture, by acceptance hereof, agrees that
this Debenture is being acquired for investment and that such Holder will not
offer, sell or otherwise dispose of this Debenture or the Shares of Common
Stock issuable upon conversion thereof except under circumstances which will
not result in a violation of the Act or any applicable state Blue Sky or
foreign laws or similar laws relating to the sale of securities.

          9.      This Debenture shall be governed by and construed in
accordance with the laws of the State of New York.  Each of the parties
consents to the jurisdiction of the federal courts whose districts encompass
any part of the City of New York or the state courts of the State of New York
sitting in the City of New York in connection with any dispute arising under

                          answer approve of, consent to, or acquiesce in any
                          such proceedings or admit the material allegations

and to the extent  converted in accordance with the terms hereof.

                 NOW, THEREFORE, in consideration of the premises and the
mutual covenants contained herein and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the Company and
the Initial Investor hereby agrees as follows:

                 1.       DEFINITIONS.

                 (a)      As used in this Agreement, the following terms shall

<PAGE>   24
securities on a continuous basis ("Rule 415"), and the declaration or ordering

                 (iv)     "Registration Statement" means a registration
statement of the Company under the Securities Act.

                 (b)      As used in this Agreement, the term Investor includes

                 2.       REGISTRATION.

                 (a)      MANDATORY REGISTRATION.  The Company shall prepare
and file with the SEC, no later than thirty (30) days after the Closing Date,
either a Registration Statement on Form SB-2 covering a sufficient number of
shares of Common Stock for the Initial Investors(or any other available form),
but in no event less than 300% of the number of shares into which the
Debentures would be convertible at the time of filing of the Form SB-2, and
such Registration Statement shall state that, in accordance with the Securities
Act, it also covers such indeterminate number of additional shares of Common

Registration Statement pursuant to Section 2(a) hereof involves an underwritten
offering, the Investors acting by majority in interest of the Registrable

the Company.  The Investors who hold the Registrable Securities to be included
in such underwriting shall pay all underwriting discounts and commissions and
other fees and expenses of such investment banker or bankers and manager or
managers so selected in accordance with this Section 2(b) (other than fees and
expenses relating to registration of Registrable Securities under federal or
state securities laws, which are payable by the Company




                                      2

paid by the Initial Investor for the Debenture pursuant to the Securities
Purchase Agreement for the period from the Initial Date to the first
Computation Date, and three (3%) percent of the purchase price for each
Computation Date thereafter, to the date the Registration Statement is declared
effective by the SEC (the "Periodic Amount").  The full Periodic Amount shall
be paid by the Company in immediately available funds within three business

payable by the Company pursuant to this provision shall not be payable to the

35 days after the Company is notified by the SEC that the Registration
Statement may be declared effective or (b)  one hundred twenty (120) days after
the Closing Date and, if the Registration Statement required to be filed by the
Company pursuant to Section 2(a) has not theretofore been declared effective by

less than the number of Registrable Securities provided in Section 2(a), above,
and thereafter use its best efforts to cause each Registration Statement
relating to Registrable Securities to become effective the earlier of (i) five
days after notice from the Securities and Exchange Commission that the
Registration Statement may be declared effective, or (b) ninety (90) days after
the Closing Date, and keep the Registration Statement effective at all times
until the earliest (the "Registration Period") of (i) the date that is two
years after the Closing Date (ii) the date when the Investors may sell all
Registrable Securities under Rule 144 or (iii) the date the Investors no longer
own any of the Registrable Securities, which Registration Statement (including
any amendments or supplements thereto and prospectuses contained therein) shall
not contain any untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances in which they were made, not misleading;





                                      3
<PAGE>   26
                 (b)  Prepare and file with the SEC such amendments (including
post-effective amendments) and supplements to the Registration Statement and
the prospectus used in connection with the Registration Statement as may be
necessary to keep the Registration effective at all times during the
Registration Period, and, during the Registration Period, comply with the
provisions of the Securities Act with respect to the disposition of all
Registrable Securities of the Company covered by the Registration Statement
until such time as all of such Registrable Securities have been disposed of in
accordance with the intended methods of disposition by the seller or sellers
thereof as set forth in the Registration Statement;

                 (c)  Furnish to each Investor whose Registrable Securities are
included in the Registration Statement and its legal counsel identified to the
Company, (i) promptly after the same is prepared and publicly distributed,
filed with the SEC, or received by the Company, one (1) copy of the
Registration Statement, each preliminary prospectus and prospectus, and each
amendment or supplement thereto, and (ii) such number of copies of a
prospectus, including a preliminary prospectus, and all amendments and
supplements thereto and such other documents, as such Investor may reasonably
request in order to facilitate the disposition of the Registrable Securities
owned by such Investor;

                 (d)  Use reasonable efforts to (i) register and qualify the
Registrable Securities covered by the Registration Statement under such other
securities or blue sky laws of such jurisdictions as the Investors who hold a
majority in interest of the Registrable Securities being offered reasonably
request and in which significant volumes of shares of Common Stock are traded,
(ii) prepare and file in those jurisdictions such amendments (including post-
effective amendments) and supplements to such registrations and qualifications
as may be necessary to maintain the effectiveness thereof at all times during
the Registration Period, (iii) take such other actions as may be necessary to
maintain such registrations and qualifications in effect at all times during
the Registration Period, and (iv) take all other actions reasonably necessary
or advisable to qualify the Registrable Securities for sale in such
jurisdictions; provided, however, that the Company shall not be required in
connection therewith or as a condition thereto to (A) qualify to do business in
any jurisdiction where it would not otherwise be required to qualify but for
this Section 3(d), (B) subject itself to general taxation in any such
jurisdiction, (C) file a general consent to service of process in any such
jurisdiction, (D) provide any undertakings that cause more than nominal expense
or burden to the Company or (E) make any change in its articles of
incorporation or by-laws, which in each case the Board of Directors of the
Company determines to be contrary to the best interests of the Company and its
stockholders;

                 (e)  As promptly as practicable after becoming aware of such
event, notify each Investor of the happening of any event of which the Company
has knowledge, as a result of which the prospectus included in the Registration
Statement, as then in effect, includes an untrue statement of a material fact
or omits to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they
were made, not misleading, and use its best efforts promptly to prepare a
supplement or amendment to the Registration Statement or other appropriate
filing with the SEC to correct such untrue statement or omission, and deliver a
number of copies of such supplement or amendment to each Investor as such
Investor may reasonably request;





                                      4
<PAGE>   27
                 (f)  As promptly as practicable after becoming aware of such
event, notify each Investor who holds Registrable Securities being sold (or, in
the event of an underwritten offering, the managing underwriters) of the
issuance by the SEC of any notice of effectiveness or any stop order or other
suspension of the effectiveness of the Registration Statement at the earliest
possible time;

                 (g)  Use its commercially reasonable efforts, if eligible,
either to (i) cause all the Registrable Securities covered by the Registration
Statement to be listed on a national securities exchange and on each additional
national securities exchange on which securities of the same class or series
issued by the Company are then listed, if any, if the listing of such
Registrable Securities is then permitted under the rules of such exchange, or
(ii) secure designation of all the Registrable Securities covered by the
Registration Statement as a National Association of Securities Dealers
Automated Quotations System ("NASDAQ") "Small Capitalization" within the
meaning of Rule 11Aa2-1 of the SEC under the Securities Exchange Act of 1934,
as amended (the "Exchange Act"), and the quotation of the Registrable
Securities on the NASDAQ Small Cap Market; or if, despite the Company's
commercially reasonable efforts to satisfy the preceding clause (i) or (ii),
the Company is unsuccessful in doing so, to secure NASDAQ authorization and
quotation for such Registrable Securities and, without limiting the generality
of the foregoing, to arrange for at least two market makers to register with
the National Association of Securities Dealers, Inc. ("NASD") as such with
respect to such Registrable Securities;

                 (h)  Provide a transfer agent and registrar, which may be a
single entity, for the Registrable Securities not later than the effective date
of the Registration Statement;

                 (i)  Cooperate with the Investors who hold Registrable
Securities being offered to facilitate the timely preparation and delivery of
certificates for the Registrable Securities to be offered pursuant to the
Registration Statement and enable such certificates for the Registrable
Securities to be in such denominations or amounts as the case may be, as the
Investors may reasonably request and registered in such names as the Investors
may request; and, within three (3) business days after a Registration Statement
which includes Registrable Securities is ordered effective by the SEC, the
Company shall deliver, and shall cause legal counsel selected by the Company to
deliver, to the transfer agent for the Registrable Securities (with copies to
the Investors whose Registrable Securities are included in such Registration
Statement) an appropriate instruction and opinion of such counsel; and

                 (j)  Take all other reasonable actions necessary to expedite
and facilitate disposition by the Investor of the Registrable Securities
pursuant to the Registration Statement.

                 4.       OBLIGATIONS OF THE INVESTORS.  In connection with the
registration of the Registrable Securities, the Investors shall have the
following obligations:

                 (a)      It shall be a condition precedent to the obligations
of the Company to complete the registration pursuant to this Agreement with
respect to the Registrable Securities of a particular Investor that such
Investor shall furnish to the Company such information regarding itself, the
Registrable Securities held by it, and the intended method of disposition of
the Registrable Securities held by it, as shall be reasonably required to
effect the registration of such Registrable





                                      5
<PAGE>   28
Securities and shall execute such documents in connection with such
registration as the Company may reasonably request.  At least five (5) days
prior to the first anticipated filing date of the Registration Statement, the
Company shall notify each Investor of the information the Company requires from
each such Investor (the "Requested Information") if such Investor elects to
have any of such Investor's Registrable Securities included in the Registration
Statement.  If at least two (2) business days prior to the filing date the
Company has not received the Requested Information from an Investor (a
"Non-Responsive Investor"), then the Company may file the Registration
Statement without including Registrable Securities of such Non-Responsive
Investor;

                 (b)      Each Investor by such Investor's acceptance of the
Registrable Securities agrees to cooperate with the Company as reasonably
requested by the Company in connection with the preparation and filing of the
Registration Statement hereunder, unless such Investor has notified the Company
in writing of such Investor's election to exclude all of such Investor's
Registrable Securities from the Registration Statement; and

                 (c)      Each Investor agrees that, upon receipt of any notice
from the Company of the happening of any event of the kind described in Section
3(e) or 3(f), above, such Investor will immediately discontinue disposition of
Registrable Securities pursuant to the Registration Statement covering such
Registrable Securities until such Investor's receipt of the copies of the
supplemented or amended prospectus contemplated by Section 3(e) or 3(f) and, if
so directed by the Company, such Investor shall deliver to the Company (at the
expense of the Company) or destroy (and deliver to the Company a certificate of
destruction) all copies in such Investor's possession, of the prospectus
covering such Registrable Securities current at the time of receipt of such
notice.

                 5.       EXPENSES OF REGISTRATION.  All reasonable expenses,
other than underwriting discounts and commissions incurred in connection with
registrations, filings or qualifications pursuant to Section 3, but including,
without limitation, all registration, listing, and qualifications fees,
printers and accounting fees, the fees and disbursements of counsel for the
Company and a fee for a single counsel for the Investor not exceeding $3,500,
shall be borne by the Company.

                 6.       INDEMNIFICATION.  In the event any Registrable
Securities are included in a Registration Statement under this Agreement:

                 (a)      To the extent permitted by law, the Company will
indemnify and hold harmless each Investor who holds such Registrable
Securities, the directors, if any, of such Investor, the officers, if any, of
such Investor, each person, if any, who controls any Investor within the
meaning of the Securities Act or the Exchange Act (each, an "Indemnified
Person"), against any losses, claims, damages, liabilities or expenses (joint
or several) incurred (collectively, "Claims") to which any of them may become
subject under the Securities Act, the Exchange Act or otherwise, insofar as
such Claims (or actions or proceedings, whether commenced or threatened, in
respect thereof) arise out of or are based upon any of the following
statements, omissions or violations in the Registration Statement, or any
post-effective amendment thereof, or any prospectus included therein: (i) any
untrue statement or alleged untrue statement of a material fact contained in
the Registration Statement or any post-effective amendment thereof or the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, (ii)
any untrue statement or alleged untrue statement of a material fact





                                            6
<PAGE>   29
contained in any preliminary prospectus if used prior to the effective date of
such Registration Statement, or contained in the final prospectus (as amended
or supplemented, if the Company files any amendment thereof or supplement
thereto with the SEC) or the omission or alleged omission to state therein any
material fact necessary to make the statements made therein, in light of the
circumstances under which the statements therein were made, not misleading or
(iii) any violation or alleged violation by the Company of the Securities Act,
the Exchange Act, any state securities law or any rule or regulation under the
Securities Act, the Exchange Act or any state securities law (the matters in
the foregoing clauses (i) through (iii) being, collectively, "Violations").
The Company shall reimburse the Investors, promptly as such expenses are
incurred and are due and payable, for any legal fees or other reasonable
expenses incurred by them in connection with investigating or defending any
such Claim.  Notwithstanding anything to the contrary contained herein, the
indemnification agreement contained in this Section 6(a) shall not (I) apply to
a Claim arising out of or based upon a Violation which occurs in reliance upon
and in conformity with information furnished in writing to the Company by or on
behalf of any Indemnified Person expressly for use in connection with the
preparation of the Registration Statement or any such amendment thereof or
supplement thereto, if such prospectus was timely made available by the Company
pursuant to Section 3(b) hereof; (II) with respect to any preliminary
prospectus, inure to the benefit of any such person from whom the person
asserting any such Claim purchased the Registrable Securities that are the
subject thereof (or to the benefit of any person controlling such person) if
the untrue statement or omission of material fact contained in the preliminary
prospectus was corrected in the prospectus, as then amended or supplemented, if
such prospectus was timely made available by the Company pursuant to Section
3(b) hereof; (III) be available to the extent such Claim is based on a failure
of the Investor to deliver or cause to be delivered the prospectus made
available by the Company; or (IV) apply to amounts paid in settlement of any
Claim if such settlement is effected without the prior written consent of the
Company, which consent shall not be unreasonably withheld.  Each Investor will
indemnify the Company and its officers, directors and agents against any claims
arising out of or based upon a Violation which occurs in reliance upon and in
conformity with information furnished in writing to the Company, by or on
behalf of such Investor, expressly for use in connection with the preparation
of the Registration Statement, subject to such limitations and conditions as
are applicable to the Indemnification provided by the Company to this Section
6. Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of the Indemnified Person and shall survive
the transfer of the Registrable Securities by the Investors pursuant to Section
9.

                 (b)      Promptly after receipt by an Indemnified Person or
Indemnified Party under this Section 6 of notice of the commencement of any
action (including any governmental action), such Indemnified Person or
Indemnified Party shall, if a Claim in respect thereof is to be made against
any indemnifying party under this Section 6, deliver to the indemnifying party
a written notice of the commencement thereof and the indemnifying party shall
have the right to participate in, and, to the extent the indemnifying party so
desires, jointly with any other indemnifying party similarly noticed, to assume
control of the defense thereof with counsel mutually satisfactory to the
indemnifying party and the Indemnified Person or the Indemnified Party, as the
case may be; provided, however, that an Indemnified Person or Indemnified Party
shall have the right to retain its own counsel with the reasonable fees and
expenses to be paid by the indemnifying party, if, in the reasonable opinion of
counsel retained by the indemnifying party, the representation by such counsel
of the Indemnified Person or Indemnified Party and the indemnifying party would
be inappropriate





                                               7
<PAGE>   30
due to actual or potential differing interests between such Indemnified Person
or Indemnified Party and any other party represented by such counsel in such
proceeding.  In such event, the Company shall pay for only one separate legal
counsel for the Investors; such legal counsel shall be selected by the
Investors holding a majority in interest of the Registrable Securities included
in the Registration Statement to which the Claim relates.  The failure to
deliver written notice to the indemnifying party within a reasonable time of
the commencement of any such action shall not relieve such indemnifying party
of any liability to the Indemnified Person or Indemnified Party under this
Section 6, except to the extent that the indemnifying party is prejudiced in
its ability to defend such action.  The indemnification required by this
Section 6 shall be made by periodic payments of the amount thereof during the
course of the investigation or defense, as such expense, loss, damage or
liability is incurred and is due and payable.

                 7.       CONTRIBUTION.  To the extent any indemnification by
an indemnifying party is prohibited or limited by law, the indemnifying party
agrees to make the maximum contribution with respect to any amounts for which
it would otherwise be liable under Section 6 to the fullest extent permitted by
law; provided, however, that (a) no contribution shall be made under
circumstances where the maker would not have been liable for indemnification
under the fault standards set forth in Section 6; (b) no seller of Registrable
Securities guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
seller of Registrable Securities who was not guilty of such fraudulent
misrepresentation; and (c) contribution by any seller of Registrable Securities
shall be limited in amount to the net amount of proceeds received by such
seller from the sale of such Registrable Securities.

                 8.       REPORTS UNDER EXCHANGE ACT.  With a view to making
available to the Investors the benefits of Rule 144 promulgated under the
Securities Act or any other similar rule or regulation of the SEC that may at
any time permit the Investors to sell securities of the Company to the public
without registration ("Rule 144"), the Company agrees to:

                 (a)      make and keep public information available, as those
terms are understood and defined in Rule 144;

                 (b)      file with the SEC in a timely manner all reports and
other documents required of the Company under the Securities Act and the
Exchange Act; and

                 (c)      furnish to each Investor so long as such Investor
owns Registrable Securities, promptly upon request, (i) a written statement by
the Company that it has complied with the reporting requirements of Rule 144,
the Securities Act and the Exchange Act, (ii) a copy of the most recent annual
or quarterly report of the Company and such other reports and documents so
filed by the Company and (iii) such other information as may be reasonably
requested to permit the Investors to sell such securities pursuant to Rule 144
without registration.

                 9.       ASSIGNMENT OF THE REGISTRATION RIGHTS.  The rights to
have the Company register Registrable Securities pursuant to this Agreement
shall be automatically assigned by the Investors to any transferee of in excess
of fifty (50%) percent or more of the Registrable Securities (or all or any
portion of any Debenture of the Company which is convertible into such
securities)





                                      8
<PAGE>   31
only if:  (a) the Investor agrees in writing with the transferee or assignee to
assign such rights, and a copy of such agreement is furnished to the Company
within a reasonable time after such assignment, (b) the Company is, within a
reasonable time after such transfer or assignment, furnished with written
notice of (i) the name and address of such transferee or assignee and (ii) the
securities with respect to which such registration rights are being transferred
or assigned, (c) immediately following such transfer or assignment the further
disposition of such securities by the transferee or assignee is restricted
under the Securities Act and applicable state securities laws, and (d) at or
before the time the Company received the written notice contemplated by clause
(b) of this sentence the transferee or assignee agrees in writing with the
Company to be bound by all of the provisions contained herein.  In the event of
any delay in filing or effectiveness of the Registration Statement as a result
of such assignment, the Company shall not be liable for any damages arising
from such delay, or the payments set forth in Section 2(c) hereof.

                 10.      AMENDMENT OF REGISTRATION RIGHTS.  Any provision of
this Agreement may be amended and the observance thereof may be waived (either
generally or in a particular instance and either retroactively or
prospectively), only with the written consent of the Company and Investors who
hold a majority in interest of the Registrable Securities.  Any amendment or
waiver effected in accordance with this Section 10 shall be binding upon each
Investor and the Company.




                 11.      MISCELLANEOUS.

                 (a)      A person or entity is deemed to be a holder of
Registrable Securities whenever such person or entity owns of record such
Registrable Securities.  If the Company receives conflicting instructions,
notices or elections from two or more persons or entities with respect to the
same Registrable Securities, the Company shall act upon the basis of
instructions, notice or election received from the registered owner of such
Registrable Securities.

                 (b)      Notices required or permitted to be given hereunder
shall be in writing and shall be deemed to be sufficiently given when
personally delivered (by hand, by courier, by telephone line facsimile
transmission, receipt confirmed, or other means) or sent by certified mail,
return receipt requested, properly addressed and with proper postage pre-paid
(i) if to the Company, at Suite 23P, 100 North Arlington, Reno, Nevada 89501
ATT: Don Steffens, with a copy to Alexander H. Walker, Jr., Esq., Nevada Agency

Initial Investor, at the address set forth under its name in the Securities
Purchase Agreement, with a copy to Samuel Krieger, Esq., Krieger & Prager, 319
Fifth Avenue, Third Floor, New York, NY 10016 and (iii) if to any other
Investor, at such address as such Investor shall have provided in writing to
the Company, or at such other address as each such party furnishes by notice
given in accordance with this Section 11(b), and shall be effective, when
personally delivered, upon receipt and, when so sent by certified mail, four
(4) calendar days after deposit with the United states Postal Service.

                 (c)      Failure of any party to exercise any right or remedy
under this Agreement or otherwise, or delay by a party in exercising such right
or remedy, shall not operate as a waiver thereof.

                 (d)      This Agreement shall be governed by and interpreted
in accordance with the laws of the State of New York.  Each of the parties
consents to the jurisdiction of the federal courts whose districts encompass
any part of the City of New York or the state courts of the State of New York
sitting in the City of New York in connection with any dispute arising under
this Agreement and hereby waives, to the maximum extent permitted by law, any
objection, including any objection based on forum non coveniens, to the
bringing of any such proceeding in such jurisdictions.  A facsimile
transmission of this signed Agreement shall be legal and binding on all parties
hereto.  This Agreement may be signed in one or more counterparts, each of
which shall be deemed an original.  The headings of this Agreement are for
convenience of reference and shall not form part of, or affect the
interpretation of, this Agreement.  If any provision of this Agreement shall be
invalid or unenforceable in any jurisdiction, such invalidity or
unenforceability shall not affect the validity or enforceability of the
remainder of this Agreement or the validity or enforceability of this Agreement
in any other jurisdiction.  This Agreement may be amended only by an instrument
in writing signed by the party to be charged with enforcement.  This Agreement
supersedes all prior agreements and understandings among the parties hereto
with respect to the subject matter hereof.

                 (e)      This Agreement constitutes the entire agreement among
the parties hereto with respect to the subject matter hereof.  There are no
restrictions, promises, warranties or undertakings, other than those set forth
or referred to herein.  This Agreement supersedes all prior agreements and
understandings among the parties hereto with respect to the subject matter
hereof.

                 (f)      Subject to the requirements of Section 9 hereof, this
Agreement shall inure to the benefit of and be binding upon the successors and
assigns of each of the parties hereto.
