                               PROSPECTUS SUMMARY



     This summary highlights information contained elsewhere in this prospectus.
You should read the entire prospectus carefully. All information in this
prospectus reflects a six-for-one split of the Common Stock resulting from a six
share Common Stock dividend on each outstanding share on September 9, 1998 and a
six-for-seven reverse stock split on June 8, 1999.



                          IMPLANT SCIENCES CORPORATION



     Over the past fifteen years, we have developed core technologies using ion
implantation and thin film coatings for medical device applications and have
proprietary processes and equipment for the manufacture of radiation therapy
implants.



     - On May 26, 1999 we received notification of pre-market clearance from the
       Food and Drug Administration for our radioactive iodine-125 seed used for
       the treatment of prostate cancer.



     -  Our technology permits us to manufacture radioactive prostate seeds
        using a nonradioactive fabrication process which we believe will be more
        cost effective and less hazardous than conventional processes which use
        radioactive wet chemistry.



     -  Our iodine-125 prostate seeds will be assembled and sealed and then made
        radioactive in a nuclear reactor prior to shipment to customers which is
        expected to occur in the first quarter of 2000.



     -  We have a joint development agreement with a major stent manufacturer to
        develop radioactive coronary stents for the prevention of restenosis
        (reclosure of the artery) after balloon angioplasty.



     - We currently use our technologies to modify surfaces to reduce
       polyethylene wear generation in artificial knees and hips.



     - We supply ion implantation services to numerous semiconductor
       manufacturers, research laboratories and universities.



PROPOSED PRODUCTS



     PROSTATE SEEDS.  Radioactive seeds are used primarily in the treatment of
prostate cancer. This treatment, known as brachytherapy, involves implanting
approximately 100 radioactive seeds (encapsulated radioactive material,
approximately half the size of a grain of rice) directly into the prostate. This
procedure is usually performed on an outpatient basis and permits a rapid
recovery. A published ten-year study conducted by the Northwest Hospital,
Seattle, Washington shows that this treatment has a ten-year disease-free
survival rate equal to surgical removal of the prostate and may be superior to
other early stage treatments, with a substantial reduction of the negative side
effects -- impotence and incontinence -- frequently associated with surgery and
external beam radiation treatment.



     The American Cancer Society estimates that in 1998 about 184,500 new cases
of prostate cancer were diagnosed and 39,200 men died of the disease in the
United States. According to the American Cancer Society, 58% of diagnosed cases
the cancers are localized in the prostate. These cases are potential candidates
for brachytherapy.



     RADIOACTIVE STENTS.  According to the American Heart Association,
restenosis (narrowing of the artery) occurs following 30% - 40% of balloon
angioplasty procedures. Researchers in a number of studies at the Washington
Hospital Center, the Emory University School of Medicine and the Scripps Clinic
have found that the frequency of restenosis has been reduced when the artery is
treated with therapeutic radiation. By implanting therapeutic radioactivity onto
a stent, the patient can receive the appropriate

                                        4
<PAGE>   5

dose of radiation within the coronary artery without significantly affecting the
surrounding tissue.


     We have developed an ion implantation device which can accelerate and embed
radioactive atoms onto the surface of a metal stent. We intend to implant
therapeutic radioactivity into stents manufactured by our customers.


CURRENT PRODUCTS AND SERVICES


     ORTHOPEDIC IMPLANTS.  We implant nitrogen ions in the metal surfaces of
knee and hip total joint replacements manufactured by our customers to reduce
wear and thereby increase the life of the implant. The generation of wear debris
is one of the leading causes of deterioration of the bone surrounding the
implant, which causes implant loosening and ultimately the need for revision
surgery. In fiscal 1998, we ion implanted approximately 50,000 metal components
used in knee and hip total joint replacements for the Howmedica/Osteonics
Division of Stryker Corporation and Biomet Incorporated. See "Risk Factors -- We
depend on a small number of major customers."



     SEMICONDUCTOR ION IMPLANTATION.  We supply ion implantation services to
numerous semiconductor manufacturers, research laboratories, and universities.
Many of our customers provide semiconductor circuits and wafers to the
communications satellite and cellular telephone markets.


SALES


     In fiscal 1998, we had revenue of approximately $2,904,000. All of our
revenue was derived from nitrogen ion implantation of total hip and knee joint
replacements, ion implantation of semiconductors, government research grants,
and contract research. We have not sold any radioactive prostate seeds or
radioactive coronary stents for commercial use.

                                  RISK FACTORS



     An investment in our company involves a high degree of risk and units
should not be purchased by anyone who cannot afford the loss of their entire
investment. You should carefully consider all of the risk factors discussed
below as well as all other information in this Prospectus, before purchasing
units. The risks described below are not all the risks facing Implant.
Additional risks, including those not currently known to us or that we currently
deem immaterial, may also impair our business operations.



WE EXPECT TO HAVE CONTINUING LOSSES



     During the nine months ended March 31, 1999, we had a net loss of
approximately $215,000. We plan to further increase expenditures to complete
development and commercialize our new products, to increase our manufacturing
capacity and equipment, to ensure compliance with the U.S. Food and Drug
Administration's Quality System Regulations and broaden our sales and marketing
capabilities. As a result, we believe that we will incur losses over the next
several quarters.



WE HAVE SIGNIFICANT COMPETITION IN AN ENVIRONMENT OF RAPID TECHNOLOGICAL CHANGE



     North American Scientific, Inc., Theragenics, Inc. and Nycomed Amershan plc
currently produce radioactive seeds. In addition, there are technologies that
compete with our proposed radioactive stents. Among the most closely competing
products in intracoronary radiation therapy are radioactive tipped guidewires
and radioactive fluid-filled balloons. For more information, see
"Business -- Competition."



THE MEDICAL COMMUNITY MAY NOT ACCEPT OUR PRODUCTS



     Market acceptance for our products and services will depend upon a number
of factors, including:



     - The receipt and timing of Food and Drug Administration regulatory
       approvals for our radioactive stents.



     - The establishment and demonstration in the medical community and among
       health care payers of the clinical safety, efficacy and cost
       effectiveness.



     - Acceptance by the medical community of our radioactive seeds and
       radioactive coronary stents.



     - Our ability to enter into favorable agreements to distribute our
       products.



WE MAY NOT BE ABLE TO SUCCESSFULLY COMPLETE DEVELOPMENT OF OUR PRODUCTS



     Our product development efforts are subject to the risks inherent in the
development of medical devices. These risks include the possibility that:



     - Our products will be found to be ineffective or unsafe.



     - Our products will fail to receive necessary regulatory clearances or
       approvals.



     - Our products will be difficult to manufacture on a large scale or be
       uneconomical to market.



     - The proprietary rights of third parties will interfere with our product
       development.



     - Third parties will market superior or equivalent products which achieve
       greater market acceptance.


                                        8
<PAGE>   9


     We do not know if we will be able to conduct our product development
efforts within the time frames currently anticipated or that such efforts will
be completed successfully.



WE COULD INCUR MATERIAL COSTS IF OUR PRODUCTS INFRINGE, OR ARE ACCUSED OF
INFRINGING, THE INTELLECTUAL PROPERTY RIGHTS OF OTHERS



     We are aware of a U.S. patent of a third party having broad claims covering
radioactive stents and methods of using radioactive stents for the treatment of
restenosis. We have not sought a formal opinion of counsel regarding the
validity of this patent or whether our processes may infringe this patent. We
plan to implant radioactivity into coronary stents manufactured by the patent
holder, its licensees or others. If we implant radioactivity onto stents that
are not manufactured by the patent holder or its licensees this patent holder
may seek to enforce the patent against us.



     If the patent holder seeks to enforce the patent against us, we may be
required to engage in costly and protracted litigation; discontinue the
manufacture or activation of radioactive stents; develop non-infringing
technology; or enter into a license arrangement with respect to the patent. We
may not be able to develop non-infringing technology. We cannot be sure that any
necessary licenses would be available, or that, if available, such licenses
could be obtained on commercially reasonable terms. Litigation might result in
the patent holder obtaining an injunction which would prevent us from implanting
radioactivity into stents. In addition, the costs associated with defending a
patent infringement claim are significant, and even if we ultimately win such a
claim could have a material adverse effect on our business.



WE DEPEND ON PATENTS AND PROPRIETARY TECHNOLOGY



     Although we have nine United States patents issued and fifteen United
States and two international patent applications pending for our technology and
processes, our success will depend, in part, on our ability to obtain the
patents applied for and maintain trade secret protection for our technology. The
validity and breadth of claims in medical technology patents involve complex
legal and factual questions and, therefore are highly uncertain. We do not know
if any pending patent applications or any future patent application will issue
as patents, that the scope of any patent protection, obtained will be enough to
exclude competitors, that any of our patents will be held valid if subsequently
challenged or that others will not claim rights in or ownership of the patents
and other proprietary rights held by us. We do not know if others have or will
develop similar products, duplicate any of our products or design around any of
our patents issued or that may be issued in the future. In addition, whether or
not patents are issued to us, others may hold or receive patents which contain
claims having a scope that covers aspects of our products or processes.



     We do not know if any of the patents issued to us will be challenged,
invalidated or circumvented. Patents and patent applications in the United
States may be subject to interference proceeding brought by the U.S. Patent and
Trademark Office, or to opposition proceedings initiated in a foreign patent
office by third parties. We might incur significant costs defending such
proceedings and we might not be successful.



     We also rely on unpatented proprietary technology, trade secrets and
know-how and we do not know if others will independently develop substantially
equivalent proprietary information, techniques or processes, that such
technology or know-how will not be disclosed or that we can meaningfully protect
our rights to such unpatented proprietary technology, trade secrets, or
know-how. Although we have entered into non-disclosure agreements with our
employees and consultants, we cannot be sure such non-disclosure


                                        9
<PAGE>   10


agreements will provide adequate protection for our trade secrets or other
proprietary know-how.



WE MAY NOT BE ABLE TO SUCCESSFULLY MANAGE GROWTH



     We have very limited experience in the commercial production of radioactive
seeds or the commercial implantation of therapeutic radiation onto coronary
stents. Our future success will depend upon, among other factors, our ability
to:



     - Recruit, hire, train and retain highly educated, skilled and experienced
       management and technical personnel.



     - Generate capital from operations.



     - Scale-up our manufacturing process and expand our facilities.



     - Manage the effects of growth on all aspects of our business, including
       research, development, manufacturing, distribution, sales and marketing,
       administration and finance.



     Any failure on our part to manage any aspect of the growth, including the
ones listed above, of our business could have a material adverse effect on our
business.



WE DEPEND ON A SMALL NUMBER OF MAJOR CUSTOMERS



     Approximately 48% of our sales in fiscal 1998 were made to the Howmedica/
Osteonics Division of Stryker Corporation and Biomet Incorporated. All of these
sales were of nitrogen ion implantation of orthopedic joint implants. We do not
have any significant purchase commitments from these customers extending beyond
one year. We do not know if these customers will continue to purchase our
products and services at the same levels as in previous years or that such
relationships will continue in the future. The loss of a significant amount of
business from any of these customers would have a material adverse effect on our
business. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."



WE ARE SUBJECT TO EXTENSIVE GOVERNMENTAL REGULATION



     Our business is subject to extensive regulation principally by the Food and
Drug Administration in the United States and corresponding foreign regulatory
agencies in each country in which we will sell our products. These regulations
affect:



     - Product marketing clearances or approvals.



     - Product standards.



     - Packaging requirements.



     - Design requirements.



     - Manufacturing and quality assurance.



     - Labeling.



     - Import and export restrictions.



     - Tariffs and other tax requirements.



RISKS ASSOCIATED WITH HANDLING HAZARDOUS MATERIALS



     Our research activities sometimes involve the use of various hazardous
materials. Although we believe that our safety procedures for handling,
manufacturing, distributing,


                                       10
<PAGE>   11


transporting and disposing of such materials comply with the standards for
protection of human health, safety, and the environment, prescribed by local,
state, federal and international regulations, the risk of accidental
contamination or injury from these materials cannot be completely eliminated. We
cannot eliminate the risk that one or more of our hazardous material or
hazardous waste handlers may cause contamination for which, under laws imposing
strict liability, we could be held liable. While we currently maintain our
insurance in amounts which we believe are appropriate in light of the risk of
accident, we could be held liable for any damages that might result from any
such event. Any such liability could exceed our insurance and available sources
and could have a material adverse effect on our business. See
"Business -- Government Regulation."



RISKS ASSOCIATED WITH THIRD PARTY REIMBURSEMENT AND POSSIBLE HEALTH CARE REFORMS



     Medicare, Medicaid and other government insurance programs, as well as
private insurance reimbursement programs, greatly affect suppliers of health
care products. Several of our products and services, including our orthopedic
implants, radioactive seeds, radioactive coronary stents, and interventional
cardiology instruments and devices, are currently being reimbursed by third
party payers. Our customers rely on third-party reimbursements to cover all or
part of the costs of most of the procedures in which our products are used.
Third party payers may affect the pricing or relative attractiveness of our
products by regulating the maximum amount of reimbursement provided by such
payers to the physicians, hospitals and clinics using our devices, or by taking
the position that such reimbursement is not available at all. See
"Business -- Government Regulation."



RISKS OF PRODUCT LIABILITY



     Certain of our devices are designed to be used in treatments of diseases
where there is a high risk of serious medical complications or death. Although
we intend to obtain product liability insurance coverage when we commence sales
of our radioactive seeds and radioactive coronary stents, there can be no
assurance that in the future we will be able to obtain such coverage on
acceptable terms or that insurance will provide adequate coverage against any or
all potential claims. Furthermore there can be no assurance that we will avoid
significant product liability claims and the attendant adverse publicity. Any
product liability claim or other claim with respect to uninsured or underinsured
liabilities could have a material adverse effect on our business. See
"Business -- Product Liability and Insurance."



RISKS OF DEPENDENCE ON FEW SUPPLIERS



     We rely on a limited number of suppliers to provide materials used to
manufacture our products. If we cannot obtain adequate quantities of necessary
materials and services from our suppliers, there can be no assurance that we
will be able to access alternative sources of supply within a reasonable period
of time or at commercially reasonable rates. Limited sources, unavailability of
adequate quantities, the inability to develop alternative sources, a reduction
or interruption in supply or a significant increase in the price of raw
materials or services could have a material adverse effect on our business.



RISK OF DEPENDENCE ON KEY EXECUTIVES



     We are substantially dependent, for the foreseeable future, upon our
Chairman of the Board, President and Chief Executive Officer, Dr. Anthony J.
Armini and our Vice President and Chief Scientist, Dr. Stephen N. Bunker, both
of whom currently devote their full time and efforts to the management of the
company business. We have entered


                                       11
<PAGE>   12


into an employment agreement with each of these officers. If we were to lose the
services of Dr. Armini or Dr. Bunker for any significant period of time, our
business would be materially adversely affected. We maintain key man life
insurance policies of $1,000,000 and $500,000 insuring the lives of Messrs.
Armini and Bunker, respectively. See "Management."



RISKS OF CONTROL BY EXISTING STOCKHOLDERS



     Upon completion of this Offering, current principal stockholders and
management will own approximately 70.5% of the outstanding Common Stock,
assuming no exercise of options or warrants. Our principal stockholders and
current management will, as a practical matter, be able to direct the affairs of
business. In addition, the Chairman of the Board, President and Chief Executive
Officer, Anthony J. Armini, who currently owns 30.3% of the outstanding Common
Stock and currently controls 53.2% of the voting shares of the business will
after the Offering, own and control 24.3% of the voting shares. See "Principal
Stockholders."



ABSENCE OF PUBLIC MARKET



     Prior to this Offering, there has been no public market for the Units,
Common Stock or Warrants. After the Offering, an active trading market might not
develop or continue.



IMMEDIATE AND SUBSTANTIAL DILUTION



     If you buy the Units you will incur immediate and substantial dilution of
approximately $6.23 per share, or 83% of your investment in the Units (at an
initial public offering price of $7.50 per Unit), in that the net tangible book
value of the Units after this offering will be approximately $1.27 per Unit. See
"Dilution."



LEGAL RESTRICTIONS ON SALES OF SHARES UNDERLYING THE WARRANTS



     The Warrants are not exercisable unless, at the time of exercise, we have a
current prospectus covering the shares of Common Stock issuable upon exercise of
the Warrants, and such shares have been registered or deemed to be exempt under
the securities laws of the state of residence of the exercising holder of the
Warrants. Although we will use our best efforts to have all the shares of the
Common Stock issuable upon exercise of the Warrants registered or qualified on
or before the exercise date and to maintain effective a registration statement
relating thereto until the expiration of the Warrants, there can be no assurance
that it will be able to do so.



REDEMPTION OF WARRANTS



     We may redeem the Warrants at $0.20 per Warrant if the closing bid price of
the Common Stock as reported on the Nasdaq SmallCap Market (or any other market
on which the stock is then traded) averages in excess of $10.50 over a period of
20 consecutive trading days. In the event we decide to redeem the Warrants, such
Warrants would be exercisable until the close of business on the date fixed for
redemption. If any Warrant called for redemption is not exercised by such date,
it will cease to be exercisable and you will be entitled only to the redemption
price. See "Description of Securities -- Warrants."

<PAGE>   13


                                USE OF PROCEEDS



     If all 1,000,000 Units offered by this Prospectus are sold at an initial
public offering price per Unit of $7.50, the Company will receive net proceeds
of approximately $5,622,000 ($6,600,750 if the over-allotment option is
exercised in full). Net proceeds are determined after estimated commissions,
discounts and offering expenses payable by the Company.


     The Company intends to use the net proceeds of this offering for the
following purposes:

     participation, public relations,
     advertising expenses
Working capital and general corporate
  purposes...................................  $  622,000          11%
</TABLE>


     The amount and timing of working capital expenditures may vary
significantly depending upon numerous factors, including the progress of the
Company's research and development programs, the timing and costs involved in
obtaining regulatory approvals, the costs involved in filing, prosecuting and
enforcing patent claims, competing technological and market developments,
payments received under collaborative agreements, changes in collaborative
research relationships, the costs associated with potential commercialization of
the Company's products, including the development of marketing and sales
capabilities, the cost and availability of third-party financing for capital
expenditures and administrative and legal expenses.

     The Company believes that its available cash and existing sources of
funding, together with the proceeds of this offering and interest earned
thereon, will be adequate to maintain its current and planned operations for the
next 18 months.

     Until used, the Company intends to invest the net proceeds of this offering
in interest-bearing, investment-grade securities. While the net proceeds are so
invested, the interest earned by the Company on such proceeds will be limited by
available market rates. The Company intends to invest and use such proceeds so
as not to be considered an "investment company" under the Investment Company Act
of 1940, as amended.

                                DIVIDEND POLICY


     The Company has never declared or paid any cash dividends on its Common
Stock. The Company currently anticipates that it will retain all future earnings
for the expansion and operation of its business, and does not anticipate paying
cash dividends in the foreseeable future. The Company's revolving credit line,
term loan and equipment purchase facility with its principal lender prohibit the
payment of dividends other than common stock dividends.

     The following table sets forth the capitalization of the Company as of
March 31, 1999, on an actual basis and as adjusted to reflect the sale by the
Company of 1,000,000 Units offered hereby (at an initial public offering price

                                    DILUTION



     The net tangible book value of the Company's Common Stock as of March 31,
1999 was approximately ($86,482), or ($0.02) per share. Net tangible book value
per share represents the amount of the Company's total tangible assets less
total liabilities, divided by the 4,069,320 shares of Common Stock outstanding
as of May 30, 1999 (after the six-for-one split of the Common Stock resulting
from a six share Common Stock dividend on each outstanding share on September 9,
1998 and a six-for-seven reverse stock split on June 8, 1999).



     Net tangible book value dilution per share represents the difference
between the amount per share paid by new investors who purchase Units in this
Offering and the pro forma net tangible book value per share of Common Stock
immediately after completion of this Offering. After giving effect to the sale
of 1,000,000 Units in this Offering at an initial public offering price of $7.50
per Unit, after deduction of estimated underwriting discounts and commissions
and offering expenses, the pro forma net tangible book value of the Company at
March 31, 1999 would have been $6,461,652 or $1.27 per share.



     This represents an immediate increase in net tangible book value of $1.29
per share to existing shareholders, and an immediate dilution in net tangible
book value of $6.23 per share to new investors in the Offering, as illustrated
in the following table:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF


                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS


     The following discussion and analysis should be read in conjunction with
"Selected Financial Data" and the Company's Financial Statements and Notes
thereto included elsewhere in this Prospectus. The discussion in this Section
contains forward-looking statements within the meaning of Section 27A of the
Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), that
involve risks and uncertainties. The safe harbor from private actions based on
untrue statements or omissions of material fact that is provided by the two
statutory provisions does not apply to statements made in connection with an
initial public offering. The Company's actual results and the timing of certain
events may differ materially from the results discussed in the forward-looking
statements. Factors that could cause or contribute to such differences include,
but are not limited to, those discussed in "Risk Factors" and "Business."

OVERVIEW

     Implant Sciences Corporation (the "Company") was founded in 1984 by its
present CEO and initially provided ion implantation services to the aerospace
and machine tool industries. The Company had proprietary equipment and processes
which provided increased hardness, wear resistance, and corrosion resistance to
its customers' components. In 1986, the Company added its first semiconductor
ion implantation machine to compete in the semiconductor industry. The Company
now has three automated semiconductor implanters which produced annual revenues
of approximately $667,000 in fiscal 1998.

     In 1990, the Company developed, manufactured and began to sell wear testing
equipment to complement its ion implantation business. In 1994, the Company's
ion implantation business expanded into medical implants including total joint
replacements which is now the Company's largest revenue producer. By 1995, the
Company divested the wear test equipment product line through an asset sale to
Falex Corporation for a total price of $200,000 and future aggregate minimum
royalty payments of $175,000. This divestiture was made to focus the Company's
development and engineering personnel on the expanding medical device market.

     In 1993 and in 1995, the Company accepted two significant government
contracts to design, construct and install two large ion implantation systems at
customer sites. The second system was completed in 1997 for a total contract
amount of approximately $1,933,000 of which $351,000 was recognized as revenue
in fiscal 1997. After meeting its present obligations, the Company plans to
cease producing this equipment line to devote its entire engineering staff to
the medical device business. The Company continues to build ion implantation
equipment for its own use. The Company believes that its proprietary equipment
expertise is best devoted to manufacturing its own products such as radioactive
prostate seeds, radioactive stents, and coatings for orthopedic implants and
other medical devices. In addition to its three semiconductor ion implanters,
the Company now operates four implanters dedicated to medical production
including one special purpose ion implanter for the production of radioactive
stents, two implanters dedicated to research and development, and has two under
construction. At present the Company's revenues are approximately 77% from the
medical products and services business and the remainder from the semiconductor
ion implantation business.

MANAGEMENT'S DISCUSSION AND ANALYSIS



NINE MONTHS ENDED MARCH 31, 1999 AND 1998



     REVENUES.  Total revenues decreased to approximately $2,026,000 in the nine
months ended March 31, 1999 from approximately $2,128,000 in the nine months
ended March 31, 1998. The 4.8% decrease was primarily attributable to soft
semiconductor sales and a decrease in government contract and grant revenue as
three Phase I contracts reached completion during the nine months ended March
31, 1999. These decreases were offset by a 16% increase in orthopedic and
interventional cardiology medical revenues. Less than 5% of all revenues were
derived from foreign sources.



     The Company's two major customers, the Howmedica/Osteonics Division of
Stryker Corporation and Biomet, Incorporated, accounted for 54.3% and 7.8%,
respectively, of revenue in the nine months ended March 31, 1999 and 43.9% and
6.4% respectively, in the nine months ended March 31, 1998. The Company's
government contract and grant revenue accounted for 10.8% and 18.5% of revenue
for the nine months ended March 31, 1999 and 1998, respectively.



     COST OF PRODUCT AND CONTRACT RESEARCH REVENUES.  Cost of product and
contract research revenues decreased to approximately $1,217,000 from
approximately $1,297,000 for the nine months ended March 31, 1999 and decreased
as a percentage of revenues to


                                       21
<PAGE>   22


60% from 61% in the same periods. This decrease in cost is primarily
attributable to a reduction in costs of materials and government contract and
grant related costs.



     RESEARCH AND DEVELOPMENT.  Research and development expenses increased to
approximately $299,000 from approximately $233,000 in the nine months ended
March 31, 1999, a 28.3% increase, due to product development. The Company
anticipates in future periods its research and development expenses will
continue to increase in total dollars expended as a result of its new product
development plans.



     SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
expenses increase to approximately $726,000 from approximately $614,000 in the
nine months ended March 31, 1999. The 18.2% increase in selling, general and
administrative expenses is primarily attributable to increased personnel,
particularly the development of a senior management team. The Company
anticipates that in future periods its selling, general and administrative
expenses will increase in total dollars expended as a result of its plans to
commercialize new products.



FISCAL 1998 COMPARED TO FISCAL 1997


     REVENUES.  Total revenues decreased to approximately $2,904,000, in fiscal
1998, from approximately $3,030,000, in fiscal 1997. The 4.2% decrease was
primarily attributable to the completion of a one-time contract, completed in
fiscal 1997, to build one piece of customized manufacturing equipment. The
Company's medical and semiconductor businesses both experienced revenue
increases in fiscal 1998. Less than 5% of all revenues were derived from foreign
sources.

     The Company has three major customers, the Howmedica/Osteonics Division of
Stryker Corporation, Concurrent Technology Corporation and Biomet Incorporated.
Sales to Howmedica/Osteonics accounted for 48.9% of total revenues, in fiscal
1997, and 42.3% of total revenues, in fiscal 1998. Sales to Concurrent
Technology Corporation accounted for 11.6% of total revenues, in fiscal 1997,
and 0% of total revenues, in fiscal 1998. Sales to Biomet Incorporated accounted
for 4.9% of total revenues, in fiscal 1997, and 6.0% of total revenues, in
fiscal 1998.

     The Company's government contract and grant revenue accounted for less than
1% and 11% of total revenues, in fiscal 1997 and 1998, respectively, with
approximately one-third of the fiscal 1998 revenue derived from a National
Institutes of Health grant to develop radioactive coronary stents. The Company
also conducts research and development under cost sharing arrangements with its
commercial customers. Revenues under such arrangements were approximately
$110,000 and $100,000 for the years ended June 30, 1997 and 1998, respectively.

     Medical revenues increased to approximately $2,237,000, in fiscal 1998,
from approximately $2,232,000, in fiscal 1997. The increase in fiscal 1998
revenues is primarily attributable to increased contract revenue from government
contracts and grants, and increased medical coatings revenue, offset by a
decrease in orthopedic revenue primarily due to a price reduction associated
with a negotiated supply agreement.

     Semiconductor revenues increased to approximately $667,000, in fiscal 1998,
from approximately $447,000, in fiscal 1997. The 49.2% increase in semiconductor
ion implantation revenue primarily reflects an increase in customer base as well
as volume increases from existing customers.

     COST OF PRODUCT AND CONTRACT RESEARCH REVENUES.  Cost of product and
contract research increased to approximately $1,694,000, in fiscal 1998, from
approximately
                                       22
<PAGE>   23

$1,354,000, in fiscal 1997, and increased as a percentage of revenues from
44.7%, in fiscal 1997, to 58.3%, in fiscal 1998. The increase in cost is
primarily attributable to increased activity related to government contracts and
grants which generally have lower gross margins than product revenues, increased
production material costs and the absorption of fixed labor and overhead
expenses associated with the completion, in fiscal 1997, of a one-time equipment
production subcontract.

     RESEARCH AND DEVELOPMENT.  Research and development expenses increased to
approximately $307,000, in fiscal 1998, from approximately $301,000, in fiscal
1997, and increased as a percentage of revenues from 9.9%, in fiscal 1997, to
10.6%, in fiscal 1998. The increase primarily reflects an increased level of
research and development activity relating to the Company's new products, which
are radioactive prostate seeds for the treatment of prostate cancer and
radioactive and radiopaque stents for the treatment of coronary artery
reocclusion. The Company anticipates that its research and development expenses
will continue to increase in total dollars expended.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased to approximately $1,014,000, in fiscal 1998,
from approximately $626,000, in fiscal 1997, and increased as a percentage of
revenues from 20.7%, in fiscal 1997, to 34.9%, in fiscal 1998. The increase
primarily reflects the cost associated with a terminating an agreement with the
acting Financial Officer; sales and marketing expenses, personnel, travel, and
legal expenses. The Company anticipates that its selling, general and
administrative expenses will increase in total dollars as a result of its plans
to commercialize its new products.

     OTHER INCOME AND EXPENSES, NET.  Other income and expenses, net consist
primarily of interest earned on the Company's short-term investments, interest
expense on loans and rental income for machine space. Other income and expense
increased to approximately $13,000, in fiscal 1998, from ($21,000), in fiscal
1997. This increase in income primarily reflects a reduction in interest expense
due to the repayment of loans provided by officers of the Company in fiscal
1996.


     LIQUIDITY AND CAPITAL RESOURCES.  As of March 31, 1999 the Company had
approximately $100,000 in cash in the form of checking and money market
accounts. The Company also had a $300,000 revolving line of credit from a
commercial bank at a rate of prime plus one percent, of which $195,000 was
available at March 31, 1999. This line of credit expires on September 30, 1999.
The Company also has a term loan and an equipment purchase facility with a
commercial bank, under which approximately $57,000 and $750,000, respectively,
were outstanding at March 31, 1999. Under the provisions of its Loan Agreement,
the Company is required to maintain compliance with certain financial covenants,
including debt service coverage, minimum levels of net worth and restrictions on
indebtedness. At June 30, 1998, the Company's debt service coverage and net
worth was less than the required amounts. The Company's bank waived its rights
under the Loan Agreement with respect to compliance with these financial
covenants at June 30, 1998. At September 30, 1998 the Company met all of its
financial covenants. In December 1998, the Company's bank changed its loan
compliance requirements from a quarterly basis to an annual basis. The bank now
measures compliance annually, consistent with the Company's fiscal year end.
Accordingly, amounts payable under the Loan Agreement are classified as
long-term in the accompanying balance sheet.

<PAGE>   24

     During fiscal 1998, operating activities used $83,000 of cash. Net cash
used by operating activities in fiscal 1998 primarily reflects the net loss of
$58,000 and payment of offering costs.

     During fiscal 1998, investing activities used $392,000 in cash. Net cash
used by investing activities included $559,000 of purchases of property and
equipment and $31,000 of patent fees. These uses of cash were partially offset
by the redemption of short-term investments of $198,000. The Company intends to
make significant investments over the next several years to support the
development and commercialization of its products and the expansion of its
manufacturing facility. See "Use of Proceeds."

     During fiscal 1998, financing activities provided $103,000 in cash. Net
cash provided by financing activities primarily includes proceeds from an
equipment loan and the sale of the Company's Common Stock, as a result of option
exercises, offset by the repayment in full of the Company's line of credit.


     During the nine months ending March 31, 1999, operating activities used
cash of approximately $425,000 due principally to the payment of operating
expenses and offering costs and an increase in accounts receivable.



     During the nine months ending March 31, 1999, investing activities used
cash of approximately $432,000. Net cash used by investing activities included
$411,000 purchases of property and equipment and $21,000 of patent fees.
Although the Company does not have significant capital commitments, the Company
intends to make significant investments over the next several years to support
the development and commercialization of its new products and the expansion of
its manufacturing equipment.



     During the nine months ended March 31, 1999, financing activities provided
approximately $646,000 in cash. Net cash provided by financing activities
primarily includes proceeds from an equipment loan and line of credit.



     The Company plans to further increase its expenditures to complete
development and commercialize its new products, to increase its manufacturing
capacity, to ensure compliance with the FDA's Quality System Regulations and to
broaden its sales and marketing capabilities.



     The Company anticipates that the proceeds of the Offering and interest
thereon, together with existing cash and cash equivalents, will be sufficient to
fund its operations and planned new product development, including increased
working capital expenditures, through at least the next 18 months.



     During 1998 and 1999, the Company incurred operating losses and utilized
significant amounts of cash to fund operations. During this time the Company
increased its cash expenditures to develop its new products, increase capacity
and equipment and increase sales and marketing capabilities in anticipation of
FDA approval for its radioactive prostate seed (which was obtained on May 26,
1999) and radioactive stent products. The Company has been utilizing its credit
facilities and cash and cash equivalents to finance operations. In order to be
better positioned to achieve its strategic objectives, the Company is attempting
to obtain equity financing through an initial public offering of its common
stock.



     The Company has experienced delays in completing its initial public
offering. Accordingly, the Company has implemented a number of programs to
reduce its use of cash, including operating expenses reductions, while it
actively attempted to complete its


                                       24
<PAGE>   25


initial public offering. The Company believes that these programs will continue
until such time as additional sources of financing are obtained. Management of
the Company has outlined and implemented a plan of action to ensure that the
Company has adequate sources of cash to meet its working capital needs for at
least the next twelve months. The key elements of the plan are as follows:



     -  Further operating expense reductions to eliminate certain expenditures
        which are not critically essential to achieving critical business
        objectives at this time (e.g., temporary personnel, use of outside
        consultants, discretionary spending).



     -  Timing of new product development expenditures has been closely tied to
        timing of anticipated financing.



     -  Continued pursuit of government research grants.



     -  Pursuit of financing alternatives including bank financing, strategic
        alliances, and capital contributions by management.



     As a result of the above actions, management believes that its existing
cash resources and credit facilities should meet working capital requirements
over the next twelve months. However, unanticipated decreases in revenues,
increases in expenses or further delays in the process of obtaining equity
financing, may adversely impact the Company's cash position and require further
cost reductions.



YEAR 2000 COMPLIANCE


     As the year 2000 approaches, it is generally anticipated that certain
computers, software and other equipment utilizing microprocessors may be unable
to recognize or properly process dates after the year 1999 without software
modification. The Company has evaluated this potential issue with respect to its
software, equipment, financial systems and suppliers. Expenditures by the
Company to date in connection with year 2000 compliance have not been material,
and the Company does not believe the year 2000 problem will have any material
adverse effect on its business, operations or financial condition.

                                    BUSINESS



     Certain terms are defined in a glossary beginning on page 61.


GENERAL


     Implant Sciences Corporation (the "Company") has, over the past fifteen
years, developed core technologies using ion implantation and thin film coatings
for medical device applications and has proprietary processes and equipment for
the manufacture of radiation therapy implants. The Company plans to apply this
technology to manufacture radioactive prostate seeds using a non-radioactive
fabrication process which it believes will be more cost-effective and less
hazardous than conventional processes which use radioactive wet chemistry. The
seeds will be assembled, sealed and then made radioactive in a nuclear reactor
just prior to shipment to customers. The Company believes that the opportunities
for radioactive prostate seeds will continue to grow as an attractive
alternative to other methods of treatment. On May 26, 1999, the Company received
notification of pre-market clearance for its radioactive iodine-125 seed from
the Food and Drug Administration ("FDA").


     In the interventional cardiology field, the Company has a joint development
agreement with a major stent manufacturer to develop radioactive coronary
stents. The Company believes these radioactive seeds used for the treatment of
prostate cancer and radioactive coronary stents for the prevention of restenosis
(reclosure of the artery) after balloon angioplasty, will have a significant
competitive advantage over currently existing devices.


     The Company has developed its proprietary thin film coating technology in
order to apply it to radiopaque (visible by x-ray) coatings on stents,
guidewires, catheters and other devices used in interventional cardiology
procedures. In addition, the Company is applying its ion implantation
technologies to modify surfaces to reduce polyethylene wear generation in
orthopedic joint implants, manufactured by the Howmedica/Osteonics Division of
Stryker Corporation and Biomet Incorporated. Approximately 77% of the Company's
revenues in fiscal 1998 were derived from its ion implantation of medical
products business. The Company also supplies ion implantation services to
numerous semiconductor manufacturers, research laboratories and universities.
The Company has nine issued United States patents and fifteen United States
patents pending covering its technologies and processes. The Company also has
pending two international patent applications.


     Although there are a wide range of commercial applications for the
Company's proprietary technologies, the Company has chosen to focus on the
medical device industry. Within the medical device industry, the Company is
concentrating on the prostate cancer, interventional cardiology and orthopedic
segments. The Company believes that each of these segments share similar growth
dynamics in that they represent diseases or chronic conditions that most
frequently occur in people over the age of 50. The Company expects that the
number of medical procedures performed annually in each of these segments will
continue to grow as the population in the United States over the age of 50
continues to grow. Similar trends appear in other highly developed countries.

TECHNOLOGIES

     GENERAL.  The Company uses two core technologies, ion implantation and thin
film coatings, to provide enhanced surfaces to various medical implants and
semiconductor products. With respect to each core technology, the Company has
developed proprietary

                                       26
<PAGE>   27

processes and equipment for the purpose of improving or altering the surfaces of
medical implants and semiconductor wafers.

     Ion implantation and thin film coatings are techniques first developed in
the 1970s to improve the functional surface properties of metals, ceramics and
polymers, such as friction, wear, wettability and hardness. Ion implantation was
initially developed as a means to dope semiconductors in the fabrication of
integrated circuits. The accuracy, cleanliness and controllability of this
process has made it the standard for semiconductor manufacturing. Ion
implantation is generally preferred over other surface modification methods
because it does not delaminate, does not require high temperatures and does not
deform or alter the dimensions of the treated surface.

     Thin film coatings were initially developed to interconnect transistors on
semiconductor chips. Thin films modify surfaces by layering a desired metal or
ceramic coating on the substrate material. Common thin film coating techniques
include chemical vapor deposition and physical vapor deposition.

     ION IMPLANTATION.  Ion implantation is a process by which ions
(electrically charged atoms) are accelerated to high velocity in a vacuum and
directed toward a substrate or target material. The atoms become embedded just
below the surface of the material producing an alloy composed of the atoms and
the substrate material in the near-surface region of the target material. This
surface alloy may have new mechanical, electrical, chemical, optical and other
properties. The Company believes its proprietary technology, including high
current ion sources and specialized component holding fixtures, provides higher
ion implant doses and higher beam power and yields superior surface
characteristics at lower cost than commercially available equipment.
                                   [GRAPHIC]
                      Ion implantation of a knee component


     Ion implantation can be used to embed single isotopes of radioactive
elements into components. The Company plans to use its proprietary equipment to
manufacture radioactive seed implants for the treatment of prostate cancer and
other carcinomas. The Company is in the process of developing radioactive
prostate seeds containing iodine-125, which can be manufactured without
hazardous radioactive wet chemistry, the methods currently employed by existing
suppliers. The Company has three patents pending on its process. The Company
also believes it can cost-effectively implant ions of therapeutic radioisotopes
including phosphorous-32, palladium-103 or yttrium-90 into a device such as a
coronary stent used to reduce restenosis following balloon angioplasty.


     THIN FILM COATING.  A thin film coating is grown upon a substrate in a
vacuum by the gradual deposition of atoms on the substrate. The Company's
proprietary unbalanced

                                       27
<PAGE>   28

magnetron sputtering process results in coatings that are extremely dense and
free of voids, yielding good contrast and sharp edges under x-ray or
fluoroscopic examination. These coatings usually consist of gold or platinum for
radiopaque applications. The Company's proprietary manufacturing process allows
for efficient utilization of precious metals and for cost-effective recovery and
recycling of these precious metals. The Company is developing processes to coat
stents, guidewires and catheters used in interventional cardiology procedures
with substances, usually gold or platinum, that allow those stents, guidewires
and catheters to be visible under x-ray observation during a procedure. The
Company believes other techniques for applying thin film coatings are less
desirable for medical device applications because of their inability to apply a
dense coating, while continuing to be flexible and adhering to the substrate.

CURRENT AND FUTURE PRODUCTS

PROSTATE CANCER SEEDS

     GENERAL.  The alternatives generally presented to patients diagnosed with
prostate cancer are surgical removal of the prostate (radical prostatectomy) or
external beam radiation. Both techniques frequently have significant side
effects including impotence and incontinence. Brachytherapy is an increasingly
popular treatment technique whereby radioactive seeds (each of which is
approximately half the size of a grain of rice) are temporarily or permanently
implanted into the prostate. This technique allows the delivery of highly
concentrated yet confined doses of radiation directly to the prostate.
Surrounding healthy tissues and organs are spared significant radiation
exposure. Advances in transrectal ultrasound and catscan imaging equipment
provide detailed and precise measurements of prostate size and shape, for seed
distribution and placement.        [GRAPHIC]
                  Radioactive prostate seed implant procedure

     PROSTATE SEEDS.  The Company has developed, and applied for two United
States patents covering radioactive seeds, implants and methods of manufacturing
radioactive seed implants by a proprietary process. On May 26, 1999, the Company
received notice of pre-market clearance from the FDA for its radioactive
iodine-125 seed and believes these seeds should be available for commercial sale
in the first quarter of 2000. These seeds are used primarily in the treatment of
prostate cancer. This treatment, known as


                                       28
<PAGE>   29


brachytherapy, involves implanting approximately 100 radioactive seeds directly
into the prostate and is usually performed on an outpatient basis. A published
ten-year study conducted by the Northwest Hospital, Seattle, Washington (the
"Northwest Hospital Study") shows that this treatment has a ten-year
disease-free survival rate equal to surgical removal of the prostate and may be
superior to other early stage treatments, with a substantial reduction in the
negative side effects, impotence and incontinence, frequently associated with
surgery and external beam radiation treatment. The National Cancer Institute and
American Cancer Society have reported that sexual potency after implantation of
radioactive seeds has been 86% to 92%, which compares with rates of 10% to 40%
for radical prostectomies and 40% to 60% for external beam radiation therapy.
The Company's production method, involving a proprietary non-radioactive
fabrication procedure, does not use radioactive wet chemistry. Hospitals are
currently purchasing prostate seeds for approximately $45 to $55 each, for a
cost of $4,500 to $5,500 per procedure; however no assurance can be given that
these costs will remain the same. Initially the Company plans to introduce an
iodine-125 prostate seed.


     COMPETITIVE ADVANTAGES.  Management believes that the Company's
manufacturing process will result in lower capital equipment and manufacturing
assembly costs and will be less hazardous than the manufacturing processes used
by the Company's competitors. Other radioactive prostate seed manufacturers use
radioactive wet chemistry during seed assembly for iodine-125 products. These
technologies require much higher capital equipment costs than the Company's
technologies. The Company's dry process, for which it has patents pending, uses
no radioactive fabrication, and the Company believes it requires fewer personnel
and yields faster throughput. Following seed assembly the Company sends its
seeds to a nuclear reactor for activation. Using this non-radioactive
fabrication process, seeds can be fabricated and inventoried in large quantities
and activated only when ordered. Due to the short half life of iodine-125 (60
days), the competition must assemble and ship seeds on a tight schedule so they
can be implanted at the appropriate strength. For European and Asian markets,
the Company may ship and inventory "cold" seeds in overseas subsidiaries and
activate them in local nuclear reactors just prior to use. The Company currently
has no contracts with any foreign nuclear facility for activation of its
products overseas although such overseas facilities are readily available. The
Company believes these factors will result in lower manufacturing costs and,
therefore, will give the Company a cost advantage over its competitors.


     SALES.  The Company intends to manufacture and sell its own radioactive
prostate seeds to distributors of medical products and directly to major medical
centers, purchasing groups and hospitals. The Company has not yet sold any
prostate seeds for commercial use. On May 26, 1999, the Company received its
510(k) notice of pre-market clearance from the FDA for its iodine-125 seed, and
the Company believes these seeds should be available for commercial sale in the
first quarter of 2000.



     MARKETS.  Research done in 1998 by the American Cancer Society shows that
prostate cancer is the second most common cancer in American men, after skin
cancer. The American Cancer Society estimated that in 1998 about 184,500 new
cases of prostate cancer were diagnosed and 39,200 men will die of the disease
in the United States. According to the National Cancer Institute, over 80% of
prostate cancer is found in men over the age of 65. The National Cancer
Institute estimates that approximately 19 out of every 100 men born today will
be diagnosed with prostate cancer during their lifetimes. According to the
American Cancer Society, these numbers approximate the incidence and mortality
for breast cancer in women. According to the American Cancer Society, in 58% of
diagnosed cases, the cancers are localized in the prostate. These cases are
potential candidates for brachytherapy.


                                       29
<PAGE>   30


     Radical prostectomies and external beam radiation treatments are procedures
that are frequently used and have significant side effects including impotence
or incontinence. The Company believes brachytherapy is an attractive alternative
to surgery or external beam radiation for these cases because research to date
has shown that it has a lower incidence of these side effects.


     The Company believes that there is currently a shortage of certain
radioactive seeds, although this situation may change as new competitors enter
this market and existing competitors increase production capacity.

INTERVENTIONAL CARDIOLOGY DEVICES

     GENERAL.  The American Heart Association estimates that in 1995, there were
approximately 434,000 balloon angioplasty procedures performed in the United
States. According to the American Heart Association, of these approximately 30%
to 40% result in restenosis after balloon angioplasty. Research by the
Washington Hospital Center, the Emory University School of Medicine and the
Scripps Clinic has shown that delivery of an appropriate dose of therapeutic
intravascular radioactivity can reduce the incidence of restenosis and therefore
the need for additional procedures. In cooperation with certain device
manufacturers, the Company is in the process of developing a number of devices
to be used in interventional cardiology procedures. Among these devices are
intravascular radioactive stents that are used to reduce restenosis following
balloon angioplasty and stents, guidewires and catheters containing radiopaque
markers. Coronary stents are made of metals which are not radiopaque and in many
cases must be coated with dense precious metals for increased visibility that is
critical to their guiding, positioning, manipulation and placement.
                                   [GRAPHIC]
               Expected therapeutic effect of a radioactive stent
                compared to a conventional stent with restenosis


     RADIOACTIVE STENTS.  The Company has two patents issued and four United
States patents pending and has one pending international patent application for,
new methods of implanting radioactivity onto coronary stents that it believes
will reduce the incidence of restenosis. Ionizing radiation is recognized as a
promising approach to reducing restenosis at the site following balloon
angioplasty by inhibiting intimal hyperplasia. Radiosotopes, when implanted into
the stent itself, have shown marked inhibition of restenosis in animal studies.
Researchers at the Washington Hospital Center, the Emory University School of
Medicine and the Scripps Clinic researched a wide number of both external and
internal methods to deliver intravascular radiation to the coronary arteries,
some of which have problems associated with excessive whole-body radiation dose
exposure to the patient and


                                       30
<PAGE>   31

cardiologist. The Company has developed a proprietary technique for the ion
implantation of both pure beta and pure x-ray emitters into stents, which
management believes has significant advantages over other methods. These
radioisotopes produce short-range radiation that only affect the targeted
tissues, rather than the entire body or region.


     In fiscal 1998, the Company was awarded a grant from the National
Institutes of Health for the first phase of a possible two phase program to
further develop its radioactive stents on a commercial basis. The Company
currently has a joint development agreement with Guidant Corporation, a major
stent manufacturer, to develop a radioactive stent for animal studies which
could lead to clinical trials. Although the Company has developed and delivered
radioactive stents under this agreement, the Company believes that radioactive
stents will not be available for clinical use before 2001. See "Risk Factors --
We are subject to extensive governmental regulation."


     RADIOPAQUE COATINGS.  The Company has developed proprietary methods for
applying radiopaque coatings onto a variety of medical devices manufactured by
its customers in order to increase the visibility of such devices during
interventional cardiology and other catheter-based procedures. These
biocompatible coatings are deposited using a proprietary unbalanced magnetron
sputtered coating process. The resulting coating is extremely dense and free of
voids yielding good contrast and sharp edges under x-ray or fluoroscopic
examination. The Company uses this process to coat stents, guidewires and
catheters. For a fractional increase in the manufacturing cost of a stent, the
Company believes its coatings can provide significant added value and enhanced
performance. The Company's thin film coatings are being evaluated by certain
customers for stents, guidewires and catheters.

     COMPETITIVE ADVANTAGES.  For manufacture of radioactive stents, the Company
uses a proprietary ion implanter that has been optimized for this application.
The Company also has developed a proprietary ion source which uses a relatively
non-toxic form of phosphorous as the radioactive phosphorous-32 source material.
The Company believes its proprietary equipment can be used for commercial
production with the safety and quality control required by the FDA. For
manufacture of its radiopaque coatings, the Company has developed a proprietary
gold coating process and has built equipment that uses unbalanced magnetron
sputtering which provides adherent coatings on implants with complex shapes
(such as stents) and which allows for efficient recovery of precious metals not
consumed in the process.

     SALES.  The Company intends to implant therapeutic radioactivity into
stents manufactured by its customers. Although the Company developed and
delivered radioactive stents for evaluation and anticipated animal studies, the
Company has not implanted radioactivity into stents for commercial sale by its
customers and cannot make any such sales until it, or its customers, has
obtained appropriate approval from the FDA. The Company believes its radioactive
stents will not be available for commercial sale before 2001.

     MARKETS.  The American Heart Association estimates that in 1995 over 58
million Americans had one or more forms of cardiovascular disease and that there
were 434,000 balloon angioplasty procedures performed in the U.S. Restenosis
occurs in approximately 30% to 40% of all such procedures. The American Society
for Therapeutic Radiology and Oncology has reported, and numerous clinical
trials have found, that delivery of an appropriate dose of therapeutic
radioactivity can reduce the incidence of restenosis and therefore the need for
additional procedures. The Company believes that stents treated with therapeutic
radiation will be an attractive alternative to traditional stents because they

                                       31
<PAGE>   32

can reduce restenosis by delivering an appropriate dose of radioactivity to the
affected site without adversely affecting the surrounding tissue.

ORTHOPEDIC TOTAL JOINT REPLACEMENTS

     GENERAL.  The Company provides surface engineering technology to
manufacturers of orthopedic hip and knee total joint replacements. The majority
of existing hip and knee joint replacements are made of a cobalt-chromium
("CoCr") femoral component that articulates against a polyethylene component.
While offering excellent biocompatibility and superior wear resistance over
prior alloys and designs and potentially longer average life than prior alloys,
CoCr devices still suffer from particle generation where the metal and
polyethylene components articulate against each other. This particle generation
has been identified as a primary cause of implant loosening due to osteolysis
requiring repeat surgery.

          Total hip replacement                 Total knee replacement

     ORTHOPEDICS.  The Company implants CoCr components of total joint
replacements manufactured by its customers with nitrogen ions. Nitrogen ion
implantation of these components reduces polyethylene wear by modifying the
native oxide present in CoCr alloys. Laboratory tests and clinical studies have
shown that nitrogen ion-implanted CoCr components offer superior performance
over untreated components, significantly reducing wear and slowing the incidence
of osteolysis which ultimately leads to revision surgery.

     The Company is currently developing zirconia and alumina ceramic ion
implantation techniques and believes they will emerge as the preferred next
generation surface treatment method for orthopedic total joint replacements.
Management believes the use of monolithic ceramic or ceramic coated femoral
components holds greater promise than other types of components in reducing
osteolysis because ceramics have wear characteristics superior to metal and are
biocompatible and inert. The Company believes monolithic ceramic hip heads are
currently employed in a limited number of hip procedures in the US. Because of

                                       32
<PAGE>   33

their brittle nature, monolithic ceramics are not likely to be utilized for
femoral knee components. As an alternative to monolithic ceramic components, the
Company's ceramic coatings of CoCr devices using its "blended interface" process
can be applied to either hip or knee joint replacements. The Company believes
that ceramic coatings of CoCr devices would combine the bulk strength of a metal
alloy with the superior surface characteristics of a ceramic. Several orthopedic
companies are considering the Company's surface treatment methods to provide
ceramic coated metal implants.

     COMPETITIVE ADVANTAGES.  The Company believes it now operates one of the
highest beam-current ion implanters used in the medical field. This equipment
has higher through-put and lower cost than equipment with a lower beam-current.
For the Company's new second generation orthopedic coating this equipment can
provide a ceramic coating with superior adhesion due to its patented "blended
interface" process.

     SALES.  The Company currently implants CoCr components of total joint
replacements made by its customers with nitrogen ions and is developing ceramic
ion implantation techniques for total joint replacements. The Company receives
untreated CoCr total joint replacements from its customers and implants them at
its facility. The Company then invoices and ships the implanted total joint
replacements to its customers. Total joint replacements treated with ceramic ion
implantation may not be sold commercially until the Company, or its customer,
has obtained appropriate approval from the FDA. The Company believes these total
joint replacements will not be available for commercial sale until after 2001.

     MARKETS.  Osteoarthritis is a natural result of the aging process and is
the predominant cause of the need for joint replacement. The Company believes
that longer life expectancy as well as the growth in the number of people over
50 will cause the demand for total joint replacement to increase. According to
the American Academy of Orthopedic Surgeons, the hip and knee total joint
replacement market was estimated to be 500,000 units in 1995 in the United
States. The Company treats approximately 50,000 units each year using its ion
implantation process for the Howmedica/Osteonics Division of Stryker Corporation
and Biomet Incorporated. Research by the Company has shown that the Company's
ceramic coatings can decrease wear debris generation by two-thirds, which the
Company believes will reduce osteolysis and thereby reduce the need for revision
surgery.

SEMICONDUCTOR ION IMPLANTATION

     The Company supplies ion implantation services to numerous semiconductor
manufacturers, research laboratories, and research universities. Ion
implantation of electronic dopants into silicon, the process by which silicon is
turned into a semiconductor, is an integral part of the integrated circuit
fabrication process. While many of the Company's customers have their own ion
implantation equipment, they often use the Company's services and specialized
expertise for research and new product development because they do not want to
interfere with production or because they are unable to perform the services
themselves.

     To serve this market, the Company offers the ion implantation of over 60 of
the 92 natural elements for its customers' research programs. The Company offers
all of the necessary dopants for silicon as well as for new materials such as
gallium arsenide, silicon carbide, indium phosphide and other advanced compound
semiconductors. The Company also performs high dose ion-implantation of silicon
and germanium to improve the crystallinity and to modify the semiconductor
properties of these materials.

PRINCIPAL SUPPLIERS


     The Company uses several principal suppliers for the materials it uses to
prepare its products. PraxAir Distributors, Inc. provides the Company with
production gases. Newark Electronics Corp. and Eaton Corporation both provide
the Company with electronic components. The Company uses Glemco, Inc.,
McMaster-Carr Supply Co., Cambridge Valve and Fitting, Inc. and Copper and Brass
Sales for its machine shop supplies, including copper, aluminum, stainless
steel, graphite and hardware. The Company uses Refining Systems, Inc. for its
supply of gold. The Company believes that adequate supplies of its required
materials will continue to be available, however, no assurances can be given
that this will be the case. See "Risk Factors -- Dependence on few suppliers."


SALES AND MARKETING

     The Company's marketing and sales methods vary according to the
characteristics of each of its main business areas. The Company's foreign sales
have comprised less than five percent of its total revenues. Sales and marketing
to the medical device and semiconductor markets are directed by the Company's
Vice President of Marketing and Sales who is assisted by the Company's Director
of Medical Devices and the Company's Director of Semiconductor Products. Sales
in the medical device and semiconductor arena are handled by three full time
salespeople, who handle both medical devices and semiconductor products. The
solicitation and proposal process for research and development contracts and
grants are conducted by the Company's President, its Chief Scientist, and its
scientific staff.

MEDICAL SALES AND MARKETING

     The Company plans to market its radioactive prostate seeds to distributors
of medical products as well as major hospitals and key physicians who might
purchase radioactive prostate seeds. The Company plans to hire additional sales
personnel to make direct calls on these potential customers. The Company plans
to market its implantation of radioactivity onto coronary stents directly to
stent manufacturers who will in turn sell the stents to hospitals.


     In the provision of ion implantation for total joint replacements, the
Company concentrates on identifying and serving leading manufacturers. Where
possible, the Company attempts to become the sole provider of devices or surface
engineering services to each such manufacturer. The Company's marketing and
sales efforts require considerable direct contact and typically involve a
process of customer education in the merits of the Company's technology. The
Company accomplishes this by first researching customer needs, delivering
scientific papers at orthopedic and biomaterial conferences, and through
presentations at customer sites. The Company's internal research and government
research grants are an integral part of the marketing process. The Company's
patent portfolio is also very important in this process. See "Risk
Factors -- The medical community may not accept our products."


     In order to promote sales of its radiopaque coatings, the Company attends
trade shows and uses press releases. Once a customer's interest is established,
the sales process proceeds with an initial demonstration project funded by the
customer. A set of developmental runs are then performed to determine project
feasibility and to roughly optimize a parameter set for deposition. After
testing of samples generated and considering cost estimates for production
quantities, the customer may authorize the Company to proceed to pilot
production.

                                       34
<PAGE>   35

     In pilot production, typically, several hundred units are produced in a
manner equivalent to the envisioned full production method. Pilot production may
be done on an existing piece of equipment with customer/device specific
fixturing, or a prototype machine depending on the complexity of the process and
device. Samples made in pilot production are fabricated into complete devices
and used by the customer for further testing, clinical studies, FDA submissions,
and marketing and sales efforts.

     To date two types of implants have been coated for 6 companies in the
orthopedic market and 28 types of devices have been coated for 23 companies in
the interventional cardiology market. Although none have been shipped for
commercial sale, more than half of these are presently under evaluation by the
customers for commercial production.

     The Company is a party to a research and development agreement with Guidant
Corporation to develop radioactive stents for testing and commercialization by
Guidant Corporation. Guidant Corporation is required to fund the research up to
an amount totaling $375,000 provided that certain conditions are satisfied. For
the initial term of the agreement, the Company is required to deal exclusively
with Guidant Corporation in developing radioactive coronary stents and is
prohibited from entering into any discussions or agreement regarding any sale,
assignment, licensing or other disposition of any of its intellectual property
relating to radioactive coronary stents. After the initial term and at the
option of Guidant Corporation, the parties have agreed to negotiate for an
exclusive supply agreement and/or license relating to any intellectual property
arising from the research.

SEMICONDUCTOR SALES AND MARKETING

     Since semiconductor ion implantation is a standard process in all
integrated circuit fabrication, customers usually know what they want and little
education is necessary. The Company's services are promoted and sold through
trade shows, advertising in trade magazines, direct mailings and press releases.
Most sales are between $600 and $2,500 per order, take less than one day to
complete, and the entire sales effort is often conducted by telephone. Most of
the Company's sales in this area are for outsourced customer-specified ion
implantation services which the customer's own ion implantation department is
unable or unwilling to perform.

GOVERNMENT CONTRACTS

     Research and development contracts from the U.S. government must be won
through a competitive proposal process which undergoes peer review. The Company
is in frequent contact with the Department of Defense, the Department of Energy
and other agencies at conferences to stay informed of the government's needs.
The Company believes its principals and senior scientific staff have earned a
strong reputation with these and other agencies. To date the Company has been
awarded research and development contracts by the National Institute of Health,
the Department of Defense, the National Science Foundation, and the National
Aeronautics and Space Administration ("NASA").

RESEARCH AND DEVELOPMENT


     The technical staff of the Company consists of nine scientists, including
four with Ph.D. degrees, two with Masters Degrees, and three with Bachelor
Degrees and with expertise in physical sciences and engineering. All of the
Company's existing and planned products rely on proprietary technologies
developed in its research and development laboratories. The Company's research
and development efforts may be self-funded, funded by corporate partners or by
awards under the Small Business Innovative Research


                                       35
<PAGE>   36

("SBIR") program. The Company has obtained over $4,000,000 in U.S. government
grants and contracts over the past 10 years. Of this amount approximately
$160,000 and $438,000 was obtained in 1997 and 1998, respectively. The Company
also conducts research and development under cost-sharing arrangements with its
commercial customers. Revenues under such arrangements were approximately
$110,000 and $100,000 for the year ended June 30, 1997 and 1998, respectively.

PATENTS AND PROPRIETARY TECHNOLOGY


     The Company's policy is to protect its proprietary position by, among other
methods, filing United States and foreign patent applications. The Company
currently has nine issued United States patents and fifteen United States patent
applications pending. The Company has two international patent applications
pending.


     The Company has exclusive rights under patents covering the following
technologies: (i) an ion source generator which can be used in making
semiconductor devices while minimizing the use of toxic gases, (ii) a method of
using ion implantation for epitaxially growing thin films, which can be used for
semiconductor materials, (iii) a method of ion beam coating orthopedic implant
components to form a zirconium oxide interface layer with improved wear
properties, and (iv) an improved ceramic coated orthopedic implant component in
which the implant is first coated with a platinum alloy.


     The Company is aware of a U.S. patent of a third party having broad claims
covering radioactive stents and methods of using radioactive stents for the
treatment of restenosis. The Company has not sought a formal opinion of counsel
regarding the validity of this patent or whether the Company's processes
infringe this patent. The Company plans to implant radioactivity onto coronary
stents manufactured by the patent holder, its licensees or others. If the
Company's plans to implant radioactivity onto the patent holder's stents do not
succeed and/or if the Company implants radioactivity onto stents that are not
manufactured by the patent holder or its licensees there can be no assurance
that the holder of this patent will not seek to enforce the patent against the
Company or the manufacturer of the stents, or that the Company would prevail in
any such enforcement action. See "Risk Factors -- We could incur material costs
if our products infringe, or are accused of infringing, the intellectual
property rights of others."



     The Company intends to seek further patents on its technologies, if
appropriate. However, there can be no assurance that patents will issue for any
of the Company's pending or future applications or that any claim allowed from
such applications will be of sufficient scope or strength, or be issued in all
countries where the Company sells its products and services, to provide
meaningful protection or any commercial advantage to the Company. See "Risk
Factors -- We depend on patents and proprietary technology."


GOVERNMENT REGULATION AND ENVIRONMENTAL MATTERS


     Although the Company's present business itself is not directly regulated by
the FDA, the medical devices incorporating its technologies are subject to FDA
regulation. The burden of securing FDA clearance or approval for these medical
devices rests with the Company's medical device manufacturers or licensees.
However, the Company intends to prepare Device Master Files which may be
accessed by the FDA to assist it in its review of the applications filed by the
Company's medical device manufacturers. The Company's radioactive iodine-125
seed is subject to the FDA's 510(k) notification of pre-market clearance, which
was granted by the FDA on May 26, 1999.


                                       36
<PAGE>   37


     Supplemental or full pre-market approval ("PMA") reviews require a
significantly longer period. A PMA will be required for the Company's
radioactive coronary stents. Thus, significantly more time will be required to
commercialize applications subjected to PMA review. The Company believes its
radioactive coronary stents will not be available for commercial sale before
2001. Furthermore, sales of medical devices outside the U.S. are subject to
international regulatory requirements that vary from country to country. The
time required to obtain clearance or approval for sale internationally may be
longer or shorter than that required for FDA approval. See "Risk Factors -- we
are subject to extensive governmental regulation."


     In addition to FDA regulation, certain of the Company's activities are
regulated by, and require approvals from, other federal and state agencies. For
example, aspects of the Company's operations require the approval of the
Massachusetts Department of Public Health and registration with the Department
of Labor and Industries. Furthermore, the Company's use, management,
transportation, and disposal of certain chemicals and wastes are subject to
regulation by several federal and state agencies depending on the nature of the
chemical or waste material. Certain toxic chemicals and products containing
toxic chemicals may require special reporting to the United States Environmental
Protection Agency and/or its state counterparts. The Company is not aware of any
specific environmental liabilities that it could incur. The Company's future
operations may require additional approvals from federal and/or state
environmental agencies.

FACILITIES AND EQUIPMENT


     Pursuant to a lease, dated July 29, 1998, the Company operates from a
21,992 sq. ft. leased facility in Wakefield, Massachusetts. The Company
currently operates nine ion implantation machines, and has two more under
construction by its own technical staff. Four are dedicated to medical
production including one special purpose ion implanter dedicated to production
of radioactive coronary stents. Three machines are dedicated to semiconductor
ion implantation. Two are used for research and development. Five machines are
housed in class 100 clean rooms. The Company maintains a machine shop facility
on its premises and employs four machinists which allows the Company to
fabricate and customize is specialized manufacturing equipment. The Company
expects that its space will be sufficient for the next 12 months. The Company's
current lease expires in May, 2000.


COMPETITION


     In radioactive products, such as prostate seed implants and radioactive
stents, the Company expects to compete with Nycomed Amersham plc, Theragenics
Corp., North American Scientific, Inc., International Isotopes Inc., UroCore,
Inc., Uromed Corporation, and International Brachytherapy, Inc. Of these,
Nycomed Amersham plc, Theragenics Corp. and North American Scientific, Inc.
serve substantially the entire radioactive prostate seed market and
International Isotopes Inc., UroCore, Inc., Uromed Corporation, and
International Brachytherapy, Inc. have announced that they plan to enter the
prostate seed market. In addition, the Company's proposed radioactive stents
will compete with alternative technologies such as Novoste Corporation's
Beta-Cath system, radioactive tipped guidewires and radioactive filled balloons.
The number and types of procedures being performed on the prostate are
increasingly drawing new entrants into the market. The Company believes that
competition, and, in turn, pricing pressures, may increase. Many of the
Company's competitors have substantially greater financial, technical and


                                       37
<PAGE>   38


marketing resources than the Company. See "Risk Factors -- We have significant
competition in an environment of rapid technological change."



     Many medical device manufacturers have developed or are engaged in efforts
to develop internal surface modification technologies for use on their own
products. Most companies that market surface modification to the outside
marketplace are divisions of organizations with businesses in addition to
surface modification. Overall, the Company believes the worldwide market for
surface modification technologies applicable to medical devices is very
fragmented with no competitor having more than a 10% market share. Many of the
Company's existing and potential competitors (including medical device
manufacturers pursuing coating solutions through their own research and
development efforts) have substantially greater financial, technical and
marketing resources than the Company. See "Risk Factors -- We have significant
competition in an environment of rapid technological change."



     With respect to ion implantation of orthopedic implants, the Company
primarily competes with Spire Corporation. Competition within the orthopedic
implant industry is primarily conducted on the basis of service and product
design. Price competition has abated somewhat in the case of first time and more
youthful patients where higher-cost and more durable reconstructive devices are
preferred. The Company attempts to differentiate itself from its competition by
providing what it believes are high value-added solutions to surface
modification. Management believes that the primary factors customers consider in
choosing a particular surface modification technology are performance, ease of
manufacturing, ability to produce multiple properties from a single process,
compliance with manufacturing regulations, customer service, pricing, turn
around time, and the ability to work with a variety of materials. The Company
believes that its process competes favorably with respect to these factors. The
Company believes that the cost and time required to acquire equipment and
technical engineering talent, as well as to obtain the necessary regulatory
approvals, significantly reduces the likelihood of a manufacturer changing the
coating process it uses after a device has been approved for marketing. See
"Risk Factors -- We have significant competition in an environment of rapid
technological change."


     The Company's primary competition in the semiconductor industry consists of
three companies: Ion Implant Services, The Implant Center, and Ion Implant
Corporation. These companies are all located in Silicon Valley, California and
primarily serve the silicon wafer production needs of semiconductor factories in
their local area, although Ion Implant Corporation does research and development
implants nationwide. The Company mostly serves east coast factories with silicon
production and research and development laboratories worldwide.


     Many of the Company's competitors and potential competitors have
substantially greater capital resources than the Company does and also have
greater resources and expertise in the areas of research and development,
obtaining regulatory approvals, manufacturing and marketing. There can be no
assurance that the Company's competitors and potential competitors will not
succeed in developing, marketing and distributing technologies and products that
are more effective than those developed and marketed by the Company or that
would render the Company's technology and products obsolete or noncompetitive.
Additionally, there is no assurance that the Company will be able to compete
effectively against such competitors and potential competitors in terms of
manufacturing, marketing and sales. See "Risk Factors -- We have significant
competition in an environment of rapid technological change."

PRODUCT LIABILITY AND INSURANCE


     The Company's business entails the risk of product liability claims.
Although the Company has not experienced any product liability claims to date,
there can be no assurance that such claims will not be asserted or that it will
have sufficient resources to satisfy any liability resulting from such claims.
The Company intends to acquire product liability insurance when its radioactive
prostate seed products and interventional cardiology devices are in commercial
production. There can be no assurance that product liability claims will not
exceed such insurance coverage limits, that such insurance will continue to be
available on commercially reasonable terms or at all, or that a product
liability claim would not materially adversely affect the business, financial
condition or results of operations of the Company. See "Risk Factors -- Risks of
product liability."


EMPLOYEES


     As of March 31, 1999, the Company employed 36 full-time individuals. The
Company believes it maintains good relations with its employees. None of the
Company's employees is represented by a union or covered by a collective
bargaining agreement. The Company's success will depend, in large part, upon its
ability to attract and retain qualified employees. The Company faces competition
in this regard from other companies, research and academic institutions and
other organizations.



REPORTS TO STOCKHOLDERS



     Implant intends to distribute to its stockholders annual reports containing
audited financial statements.

COMPENSATION OF DIRECTORS

     The Company's directors who are employees of the Company do not currently
receive any compensation for service on the Board of Directors. Directors who
are not employees of the Company, other than Mr. Shimizu, are paid a yearly
stipend of $2,500 and are reimbursed for reasonable expenses incurred in
connection with attendance at Board and committee meetings.

     Under the 1998 Incentive and Nonqualified Stock Option Plan (the "Option
Plan"), each Director who is not an employee of the Company automatically
receives an annual grant of options to purchase 2,000 shares of Common Stock at
an exercise price equal to the closing price of the Common Stock on that date
for each year of service. Each such option will have a term of five years and
will vest in full on the date of grant.

MEDICAL ADVISORY BOARD

     The Company has formed a Medical Advisory Board which will advise and
consult with the Company's Board of Directors and senior management at such
times as the Chief

                                       41

Executive Officer shall request. This advice and consultation will relate
generally to the Company's business and products. The Medical Advisory Board
advises on industry trends and new or experimental modalities of treatment in
the oncology, interventional cardiology and orthopedic specialties. The Medical
Advisory Board members may be employed on a full-time basis by employers other
than the Company, and these members may have commitments to, or consulting,
advisory or other contractual relationships with, other third parties. These
third party commitments and relationships may limit the availability of the
Medical Advisory Board members to the Company, and may potentially result in
conflicts of interest. Consultations with Medical Advisory Board members may be
either individually or as a group depending upon board member availability. To
date, the following individuals have agreed to serve as members of the Medical
Advisory Board.

BENEFIT PLANS

1998 INCENTIVE AND NONQUALIFIED STOCK OPTION PLAN


     The 1998 Incentive and Nonqualified Stock Option Plan (the "1998 Option
Plan") was adopted by the Board of Directors and the shareholders of the Company
in September, 1998. A total of 240,000 shares of Common Stock will be reserved
for issuance under the 1998 Incentive and Nonqualified Stock Option Plan.
However, the Company has entered into an agreement with the Representative
pursuant to which it has agreed not to issue options to purchase more than
100,000 shares of Common Stock in the next 18 months. The 1998 Option Plan will
authorize (i) the grant of options to purchase Common Stock intended to qualify
as incentive stock options ("Incentive Options"), as defined in Section 422 of
the Code and (ii) the grant of options that do not so qualify ("Nonqualified
Options"). The exercise price of Incentive Options granted under the 1998


                                       44
<PAGE>   45

Option Plan must be at least equal to the fair market value of the Common Stock
of the Company on the date of grant. The exercise price of Incentive Options
granted to an optionee who owns stock possessing more than 10% of the voting
power of the Company's outstanding capital stock must be at least equal to 110%
of the fair market value of the Common Stock on the date of grant.

     The 1998 Option Plan may be administered by the Board of Directors or the
Compensation Committee. Except in the case of certain formula grants to
nonemployee directors described above under "Director Compensation," the Board
or the Compensation Committee will select the individuals to whom options will
be granted and will determine the option exercise price and other terms of each
award, subject to the provisions of the 1998 Option Plan. Incentive Options may
be granted under the 1998 Option Plan to employees, including officers and
directors who are also employees. Nonqualified Options may be granted under the
1998 Option Plan to officers and other employees and to directors and other
individuals providing services to the Company, whether or not they are employees
of the Company.

1998 EMPLOYEE STOCK PURCHASE PLAN


     The 1998 Employee Stock Purchase Plan (the "Stock Purchase Plan") was
adopted by the Board of Directors and the shareholders of the Company in
September, 1998. The Stock Purchase Plan authorizes the issuance of up to an
aggregate of 141,000 shares of Common Stock to participating employees. The
Stock Purchase Plan may be administered by the Board of Directors or the
Compensation Committee.


     Under the terms of the Stock Purchase Plan, all employees of the Company
(other than seasonal employees) who have completed one year of employment with
the Company and whose customary employment is more than part-time (i.e. more
than 20 hours per week and more than five months in the calendar year) are
eligible to participate in the Stock Purchase Plan. Employees who own five
percent or more of the outstanding Common Stock of the Company and directors who
are not employees are not eligible to participate in the Stock Purchase Plan.

     The right to purchase Common Stock under the Stock Purchase Plan will be
made available through a series of one year offerings (each, an "Offering
Period"). On the first day of an Offering Period, the Company will grant to each
eligible employee who has elected in writing to participate in the Stock
Purchase Plan an option to purchase shares of Common Stock. The employee will be
required to authorize an amount (between one and ten percent of the employee's
compensation) to be deducted by the Company from the employee's pay during the
Offering Period. On the last day of the Offering Period, the employee will be
deemed to have exercised the option, at the option exercise price, to the extent
of accumulated payroll deductions. Under the terms of the Stock Purchase Plan,
the option exercise price is an amount equal to 85% of the fair market value of
one share of Common Stock on either the first or last day of the Offering
Period, whichever is lower.

     No employee may be granted an option that would permit the employee's
rights to purchase Common Stock to accrue at a rate in excess of $25,000 of the
fair market value of the Common Stock, determined as of the date the option is
granted, in any calendar year.

     The Company has made no determination as to when the first Offering Period
under the Stock Purchase Plan will commence.

1992 STOCK OPTION PLAN

     The 1992 Stock Option Plan (the "1992 Option Plan") was adopted by the
Board of Directors and the shareholders in 1992. Upon the adoption of the 1998
Option Plan, the 1992 Option Plan was terminated. The 1992 Option Plan governs
only stock options outstanding under such plan. No new stock options will be
granted under the 1992 Option Plan, which has been superseded by the 1998 Option
Plan.

     The 1992 Option Plan authorized (i) the grant of options to purchase Common
Stock intended to qualify as incentive stock options ("Incentive Options"), as
defined in Section 422 of the Code, and (ii) the grant of options that did not
so qualify ("Nonqualified Options"). The exercise price of Incentive Options
granted under the 1992 Option Plan was required to be at least equal to the fair
market value of the Common Stock of the Company on the date of grant. The
exercise price of Incentive Options granted to an optionee who owned stock
possessing more than 10% of the voting power of the Company's outstanding
capital stock was required to be at least equal to 110% of the fair market value
of the Common Stock on the date of grant.

     The 1992 Option Plan was required to be administered by the Board of
Directors or a committee designated by the Board. The Board or the designated
committee was empowered to select the individuals to whom options were granted
and to determine the option exercise price and other terms of each award,
subject to the provisions of the 1992 Option Plan. The Board or a designated
committee had authority to grant Incentive Options under the 1992 Option Plan to
employees, including directors who were also employees, and to grant
Nonqualified Options to employees and to directors and other individuals
providing services to the Company, whether or not they were employees of the
Company.

VOTING TRUST AGREEMENT


     Two of the principal stockholders of the Company, Anthony J. Armini and
Patricia A. Armini, are parties to a Voting Trust Agreement, dated November 1,
1991. Under this agreement, so long as either party owns at least 25% of the

                              CERTAIN TRANSACTIONS


     Some of the transactions described below were entered into when there were
less than two disinterested independent directors.

     Between 1983 and 1994, two officers and shareholders of the Company, Dr.
Anthony J. Armini, and Dr. Stephen N. Bunker, did not receive certain
compensation. These underpayments of $562,070 for Dr. Armini and $249,755 for
Dr. Bunker were accrued by the Company as liabilities as the services were
rendered. In each of fiscal 1996 and 1997, a deferred compensation payment of
$193,252 and $119,000, respectively, was paid to Dr. Armini and $20,000 and $0,
respectively, was paid to Dr. Bunker, which payments were partial payments of
the accrued compensation due to each of them. The remaining amounts were
reflected as deferred compensation on the June 30, 1997 balance sheet. During
fiscal 1998, these two principal officers discharged the Company from its
remaining obligation.


     On December 9, 1997, the Company entered into a Loan Agreement with Anthony
J. Armini. Pursuant to the terms of this Agreement, the Company loaned $137,500
to Dr. Armini for the purpose of exercising 300,000 options granted in 1993 to
purchase Common Stock. The interest rate on the loan, which is unsecured, is six
percent per annum. The entire amount of the principal and accumulated interest
will be due on December 9, 2003.



     In December, 1997, three of the directors of the Company exercised options
issued in 1993 to purchase shares of Common Stock of the Company in the
following amounts and at the following prices (as adjusted to give effect to a
six-for-one split of the Common Stock resulting from a six share Common Stock
dividend on each outstanding share on September 9, 1998 and a six-for-seven
reverse stock split on June 8, 1999): Stephen N. Bunker purchased 300,000 shares
at a price of $.46 per share; Anthony J. Armini purchased 300,000 shares at a
price of $.46 per share; and Robert E. Hoisington purchased 30,000 shares at a
price of $.42 per share. In addition, in June, 1997, NAR Holding Corporation
exercised its preemptive rights pursuant to a 1987 agreement to purchase 301,668
shares of Common Stock of the Company at a price of $.49 per share.



     In July, 1998, as consideration for terminating an agreement with Eric
Akhund, acting chief financial officer of the Company, and his resignation from
the Company's board of directors, the Company provided the following benefits:
(i) a $60,000 lump sum cash payment; (ii) 12 additional payments of $4,125 per
month; (iii) warrants, with a three-year term, to purchase 86,640 shares of the
Common Stock of the Company at a price of $17.31 per share; (iv) 12,000 shares
of the Common Stock of the Company; and (v) the forgiveness of an $18,750
employee advance. The total cost to the Company of terminating this agreement
was $144,050. As part of Mr. Akhund's original agreement he was also provided
warrants, with a three year term, to purchase 9,000 shares of Common Stock of
the Company at a price of $1.51 per share. The Company granted piggyback
registration rights to this individual in any public offering after the initial
public offering of the Common Stock. This individual has agreed to sign a
lock-up agreement for future sale of such warrants and shares equivalent to the
lock-up agreements signed by the Company's management.



     In January, 1999, the Company entered into loan agreements aggregating
$137,500 with ten employees for the purpose of permitting these employees to
exercise options to purchase 321,642 shares of Common Stock, in the aggregate.
The interest rate of each

loan, which is unsecured, is 6% per annum. The entire principal amount and
accumulated interest on each loan will be due on January 7, 2002.

     Pursuant to an agreement with the Company, for so long as NAR Holding
Corporation owns at least 10% of the Company's issued and outstanding shares of
Common Stock, it is entitled to nominate one person for election to the Board of
Directors of the Company. Mr. Shimizu is NAR Holding Corporation's designated
director.

     Any future transactions between the Company and its officers, directors,
principal stockholders or other affiliates will be on terms no less favorable
than could be obtained from independent third parties and will be subject to
approval by a majority of the independent and disinterested directors.


                               LEGAL PROCEEDINGS


     The Company is not currently a party to any legal proceedings.

                           DESCRIPTION OF SECURITIES


     Following the closing of the sale of the Units offered hereby, the
authorized capital stock of the Company will consist of 20,000,000 shares of
Common Stock, $0.10 par value per share and 5,000,000 shares of Preferred Stock,
$0.10 par value per share.

UNITS


     Each Unit being offered by the Company consists of one share of Common
Stock and a Warrant exercisable for one share of Common Stock. The Common Stock
and Warrants which comprise the Units will trade only as units until at least 30
days after the date of the Prospectus or such later time as may be determined by
the Representative.


COMMON STOCK

     Holders of Common Stock are entitled to one vote per share in all matters
to be voted on by the shareholders. Subject to the preferences that may be
applicable to any Preferred Stock then outstanding, holders of Common Stock are
entitled to receive ratably such dividends, if any, as may be declared from time
to time by the Board of Directors out of funds legally available therefor. See
"Dividend Policy." In the event of liquidation, dissolution or winding up of the
Company, whether voluntary or involuntary, holders of Common Stock are entitled
to share ratably in all assets remaining after payment of the Company's
liabilities and the liquidation preference, if any, of any then outstanding
shares of Preferred Stock. Holders of Common Stock have no preemptive rights and
no rights to convert their Common Stock into any other securities, and there are
no redemption or sinking fund provisions with respect to such shares. The
rights, preferences and privileges of holders of Common Stock are subject to,
and may be materially adversely affected by, the rights of the holders of shares
of any series of Preferred Stock which the Company may designate and issue in
the future. All outstanding shares of Common Stock are fully paid and
non-assessable. The shares of Common Stock to be issued by the Company in the
Offering will be fully paid and non-assessable.

WARRANTS


     The following is a brief summary of certain provisions of the Warrants, but
such summary does not purport to be complete and is qualified in all respects by
reference to the actual text of the Unit and Warrant Agreement (the "Warrant
Agreement") between the Company and American Securities Transfer & Trust Inc.
(the "Transfer and Warrant Agent"). A copy of the Warrant Agreement has been
filed as an exhibit to the Registration Statement of which this Prospectus is a
part.



     Each Warrant entitles the registered holder thereof to purchase, at any
time no sooner than 30 days after the date of the Prospectus, one share of
Common Stock at a price equal to $9.00. The warrants expire three years from the
date of this Prospectus. The Warrant exercise price is subject to adjustment
under provisions referred to below. The holder of any Warrant may exercise such
Warrant by surrendering the certificate representing the Warrant to the Transfer
and Warrant Agent, with the subscription form on the reverse side of such
certificate properly completed and executed, together with payment of the
exercise price. The Warrants may be exercised at any time in whole or in part at
the applicable exercise price until expiration of the Warrants. No fractional
shares will be issued upon the exercise of the Warrants.


                                       51
<PAGE>   52

     The exercise price of the Warrants bears no relation to any objective
criteria of value and should in no event be regarded as an indication of any
future market price of the securities offered hereby.

     The exercise price and number of shares of Common Stock purchasable upon
the exercise of the Warrants are subject to adjustment upon the occurrence of
certain events, including, without limitation, stock splits, stock dividends,
recapitalizations and reclassifications.


     The Warrants are subject to redemption by the Company at $0.20 per Warrant
if the closing bid price of the Common Stock as reported on the Nasdaq SmallCap
Market averages in excess of $10.50 for a period of twenty consecutive trading
days. In the event the Company exercises the right to redeem the Warrants, such
Warrants will be exercisable until the close of business on the date of
redemption. If any Warrant called for redemption is not exercised by such time,
it will cease to be exercisable and the holder will be entitled only to the
redemption price.



     Upon separation from the Units, the Warrants will be in registered form and
may be presented to the Transfer and Warrant Agent for transfer, exchange or
exercise at any time on or prior to their expiration at which time the Warrants
become wholly void and of no value. If a market for the Warrants develops,
holders may sell Warrants instead of exercising them. There can be no assurance,
however, that a market for the Warrants will develop or continue.


     The Warrants do not confer upon holders any voting, dividend or other
rights as shareholders of the Company.

     The Company and the Transfer and Warrant Agent may make such modifications
to the Warrants that they deem necessary and desirable that do not materially
adversely affect the interests of the Warrant holders. No other modifications
may be made to the Warrants without the consent of the majority of the Warrant
holders. Modification of the number of securities purchasable upon the exercise
of any Warrant, the exercise price and the expiration date with respect to any
Warrant requires the consent of the holder of such Warrant unless such
modification occurs in connection with a stock split, stock dividend,
recapitalization, reclassification or similar event.

     No gain or loss will be recognized by a holder upon the exercise of a
Warrant. The sale of a Warrant by a holder or the redemption of a Warrant by the
Company will result in the recognition of gain or loss in an amount equal to the
difference between the amount realized by the holder and the Warrant's adjusted
basis in the hands of the holder. Provided that the holder is not a dealer in
the Warrants and that the Common Stock would have been a capital asset in the
hands of the holder had the Warrant been exercised, gain or loss from the sale
or redemption of Warrant will be long-term or short-term capital gain or loss to
the holder. Loss on the expiration of the Warrant, equal to the Warrant's
adjusted basis in the hands of the holder, will be long-term or short-term
capital loss, depending on whether the Warrant had been held for more than one
year.

THE ABOVE DISCUSSION DOES NOT ADDRESS ALL OF THE TAX CONSIDERATIONS THAT MAY BE
RELEVANT TO A PARTICULAR PURCHASER. ACCORDINGLY, ALL PROSPECTIVE PURCHASERS ARE
ADVISED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE FEDERAL, STATE, LOCAL
AND FOREIGN TAX CONSEQUENCES OF THE PURCHASE OF THE UNITS AND THE OWNERSHIP AND
DISPOSITION OF THE WARRANTS AND THE COMMON STOCK.

PREFERRED STOCK

     The Board of Directors is authorized, subject to limitations prescribed by
Massachusetts law, to provide for the issuance of Preferred Stock in one or more
series, to establish from time to time the number of shares to be included in
each such series, and to fix the designations, preferences, voting powers,
qualifications and special or relative rights or privileges thereof. The Board
of Directors is authorized to issue Preferred Stock with voting, conversion and
other rights and preferences that could adversely affect the voting power or
other rights of the holders of Common Stock. Although the Company has no current
plans to issue such shares, the issuance of Preferred Stock or of rights to
purchase Preferred Stock could have the effect of making it more difficult for a
third party to acquire, or of discouraging a third party from attempting to
acquire, a majority of the outstanding voting stock of the Company. As of the
date of this Prospectus, there were no shares of Preferred Stock outstanding.

     The Company has agreed with the Representative that it will not issue any
shares of Preferred Stock for a period ending thirteen months after date of this
Prospectus, without the prior written consent of the Representative. See
"Underwriting." The Company will issue preferred stock only with the approval of
a majority of the independent directors who do not have an interest in the
transaction and who have access, at the Company's expense, to the Company's or
independent legal counsel.


REPRESENTATIVE'S WARRANT



     At the closing of this Offering, the Company will issue to the
Representative Warrants (the "Representative's Warrants") to purchase 100,000
shares of Common Stock and 100,000 Redeemable Warrants. The Representative's
Warrants will be exercisable for a four-year period commencing one year from the
date of this Prospectus. The exercise price of the Representative's Warrants
will be $12.00. The Representative's Warrants will not be transferable prior to
their exercise date except to officers of the Representative and members of the
syndicate and officers and partners thereof. The Representative's Warrants will
contain provisions providing adjustment in the event of any recapitalization,
reclassification, stock dividend, stock split or similar transaction. The
Representative's Warrants and the securities issuable upon their exercise may
not be offered for sale except in compliance with the applicable provisions of
the Securities Act. The Company has agreed that, for a period of five years from
the date of this Prospectus, if the Company intends to file a registration
statement for the public sale of securities (other than a registration statement
on Form S-4, S-8 or a comparable registration statement), it will notify all of
the holders of the Representative's Warrants and securities issued upon exercise
thereof, and if so requested, it will include therein material to permit a
public offering of the securities underlying the Representative's Warrants
solely at the expense of the Company (excluding fees and expenses of the
Holder's counsel and any underwriting or selling commissions). See
"Underwriting."


REGISTRATION RIGHTS


     The Company has granted registration rights to the holders of the
Representative's Warrants, which provides the holders with certain rights to
register the shares of Common Stock underlying the Representative's Warrants. In
addition, for a period of five years from the date of this Prospectus, upon
written demand of the holders of a majority of the Representative's Warrants,
the Company has agreed, on one occasion, to promptly register the underlying
securities solely at the expense of the Company (excluding fees and


                                       53
<PAGE>   54

expenses of the holder's counsel and any underwriting or selling commissions).
Additionally, for a period of five years from the date of this Prospectus, upon
written demand of any holder, the Company has agreed, on one occasion, to
promptly register the underlying securities for purposes of a public offering,
solely at the expense of such holder. See "Underwriting."

     The Company has also granted to a former consultant piggyback registration
rights in any public offering after the initial public offering of the Common
Stock.

MASSACHUSETTS LAW

     Following the Offering, the Company expects that it will have more than 200
stockholders, as a result of which it will be subject to the provisions of
Chapter 110F of the Massachusetts General Laws, an anti-takeover law. In
general, this statute prohibits a publicly held Massachusetts corporation from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
becomes an interested stockholder, unless either (i) prior to that date, the
Board of Directors approved either the business combination or the transaction
in which the person became an interested stockholder, (ii) the interested
stockholder acquires 90% of the outstanding voting stock of the corporation
(excluding shares held by certain affiliates of the corporation) at the time it
becomes an interested stockholder or (iii) the business combination is approved
by the Board of Directors and by the holders of two-thirds of the outstanding
voting stock of the corporation (excluding shares held by the interested
stockholder) voting at a meeting. In general, an "interested stockholder" is a
person who owns 5% (15% in the case of a person eligible to file a Schedule 13G
under the Securities Act with respect to the Common Stock) or more of the
outstanding voting stock of the corporation or who is an affiliate or associate
of the corporation and was the owner of 5% (15% in the case of a person eligible
to file a Schedule 13G under the Securities Act with respect to the Common
Stock) or more of the outstanding voting stock within the prior three years. A
"business combination" includes mergers, consolidations, stock and asset sales,
and other transactions with the interested stockholder resulting in a financial
benefit (except proportionately as a stockholder of the corporation) to the
interested stockholder. The Company may at any time amend its Articles or
By-Laws to elect not to be governed by Chapter 110F by a vote of the holders of
a majority of its voting stock. Such an amendment would not be effective for
twelve months and would not apply to a business combination with any person who
became an interested stockholder prior to the date of the amendment.

     The Company's By-Laws provide that any holder of 10% or more of the
outstanding shares of Common Stock may call a meeting of stockholders.

LIMITATION OF LIABILITY

     The Company's Articles provide that no director of the Company shall be
personally liable to the Company or to its stockholders for monetary damages for
breach of fiduciary duty as a director, except that the limitation shall not
eliminate or limit liability (i) for any breach of the director's duty of
loyalty to the Company or its stockholders, (ii) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 61 or 62 of Chapter 156B of the Massachusetts General
Laws, dealing with liability for unauthorized distributions and loans to
insiders, respectively, or (iv) for any transaction from which the director
derived an improper personal benefit.

                                       54
<PAGE>   55

     The Company's Articles and By-Laws further provide for the indemnification
of the Company's directors and officers to the fullest extent permitted by
Section 67 of Chapter 156B of the Massachusetts General Laws, including
circumstances in which indemnification is otherwise discretionary.

     A principal effect of these provisions is to limit or eliminate the
potential liability of the Company's directors for monetary damages arising from
breaches of their duty of care, unless the breach involves one of the four
exceptions described in (i) through (iv) above. These provisions may also shield
directors from liability under federal and state securities laws.

TRANSFER AGENT AND WARRANT AGENT

     The Transfer Agent and Registrar for the Units, the Common Stock and the
Warrants is American Securities Transfer and Trust Inc., Denver, Colorado.


                        SHARES ELIGIBLE FOR FUTURE SALE



     Prior to this Offering, there has been no public market for the securities
of the Company. Future sales of substantial amounts of Units or Common Stock in
the public market could materially adversely affect the market price of such
securities. As described below, only a limited number of shares will be
available for sale shortly after this Offering, due to certain contractual and
legal restrictions on resale. Nevertheless, sales of substantial amounts of the
Company's Units or Common Stock in the public market or the perception that such
sales could occur after such restrictions lapse could materially adversely
affect the market price of the Units, Common Stock and Warrants and the ability
of the Company to raise equity capital in the future.



     Upon completion of this Offering, the Company will have outstanding
5,069,320 shares of Common Stock, assuming no exercise of the Underwriters'
over-allotment option and no exercise of outstanding options. The Units
consisting of 1,000,000 shares of Common Stock and the Warrants to purchase
1,000,000 shares of Common Stock that are to be sold by the Company to the
public in this Offering will be freely tradable without restriction under the
Securities Act, unless purchased by affiliates of the Company as that term is
defined in Rule 144 under the Securities Act.



     The remaining 4,069,320 shares of Common Stock outstanding upon completion
of this Offering will be restricted securities as that term is defined in Rule
144 under the Securities Act ("Restricted Shares"). Restricted Shares may be
sold in the public market only if registered or if they qualify for an exemption
from registration under Rule 144 or 701 promulgated under the Securities Act,
which are summarized below. Sales of the Restricted Shares in the public market,
or the availability of such shares for sale, could materially adversely affect
the market price of the Common Stock and Warrants. In general, under Rule 144 as
currently in effect, beginning 90 days after the date of this Prospectus, a
person (or persons whose shares are aggregated) who has beneficially owned
Restricted Shares for at least one year (including the holding period of any
owner other than an affiliate of the Company) would be entitled to sell within
any three-month period a number of shares that does not exceed the greater of
(i) one percent of the number of shares of Common Stock then outstanding or (ii)
the average weekly trading volume of the Common Stock during the four calendar
weeks preceding the filing of notice of such sale. Sales under Rule 144 are also
subject to certain manner of sale provisions and notice requirements and to the
availability of current public information about the Company.


                                       55
<PAGE>   56

Under Rule 144(k), a person who is not deemed to have been an affiliate of the
Company at any time during the three months preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years
(including the holding period of any owner other than an affiliate of the
Company), is entitled to sell such shares without complying with the manner of
sale, public information volume limitations or notice provisions of Rule 144.

     Any employee, officer or director of or consultant to the Company who
purchased shares pursuant to a written compensatory plan or contract may be
entitled to rely on the resale provisions of Rule 701. Rule 701 permits
affiliates of the Company to sell their Rule 701 shares under Rule 701 without
complying with the holding period requirements of Rule 144. Rule 701 further
provides that non-affiliates may sell such shares in reliance on Rule 144
without having to comply with the public information, volume limitation or
notice requirements of Rule 144. In both cases, a holder of Rule 701 shares is
required to wait until 90 days after the date of this Prospectus before selling
such shares.


     Holders of all 4,069,320 restricted shares of Common Stock, including
officers and directors and holders of five percent or more of the Common Stock,
have entered into contractual lock-up agreements providing that they will not
offer, sell, contract to sell or grant any option to purchase or otherwise
dispose of the shares of stock owned by them or that could be purchased by them
through the exercise of options to purchase Common Stock of the Company, for
thirteen months after the date of this Prospectus without prior written consent
of the Representative.



     In addition to the 13-month lock-up, all officers and directors holding
shares and all stockholders holding five (5%) percent or more of the outstanding
shares further agree not to publicly sell their shares until the sooner of: (1)
the public share price reaches $15.00 and maintains that level for 20
consecutive days or (2) four (4) years after the initial public offering, except
for one shareholder holding 15.3% of the issued and outstanding Common Stock
(post offering) who will be locked up for two (2) years.

     The Underwriters named below have agreed, subject to the terms and
conditions of the firm commitment Underwriting Agreement between the Company,
and the Underwriters, to purchase from the Company the number of Units set forth

     The Underwriters have advised the Company that they propose to offer the
Units to the public at an offering price $7.50 per Unit and that the
Underwriters may allow to certain dealers who are members of the National

Unit.

</TABLE>



     The Company has granted to the Underwriters an over-allotment option
exercisable during the 45-day period following the date of this Prospectus to
purchase up to a maximum of 150,000 additional Units at the public offering
price, less the underwriting discount set forth on the cover page of this
Prospectus. The Underwriters may exercise such option only to satisfy
over-allotments in the sale of the Units.



     The Company has agreed to pay to the Representative a non-accountable
expense allowance equal to 3% of the total proceeds of this Offering, or
$225,000 ($258,750 if the Underwriters exercise the over-allotment option in
full), of which $62,500 has already been paid. The Underwriters do not intend to
offer or sell Units to accounts over which they exercise discretionary
authority.



     At the closing of this Offering, the Company will issue to the
Representative, for nominal consideration the Representative's Warrants to
purchase 100,000 shares of Common Stock and 100,000 Warrants exercisable at 160%
of the initial public offering price for these Securities. See "Description of
Securities -- Representative's Warrants."



     For the period during which the Representative's Warrants are exercisable,
the holder(s) will have the opportunity to profit from a rise in the market
value of the Company's Common Stock, with a resulting dilution in the interests
of the other stockholders of the Company. The holder(s) of the Representative's
Warrants can be expected to exercise them at a time which the Company would, in
all likelihood, be able to obtain any needed capital from an offering of
unissued Common Stock on terms more


                                       57
<PAGE>   58


favorable to the Company than those provided for in the Representative's
Warrants. Such facts may adversely affect the terms on which the Company can
obtain additional financing. To the extent that the Representative realizes any
gain from the resale of the Representative's Warrants or the securities issuable
thereunder, such gain may be deemed additional underwriting compensation under
the Securities Act of 1933, as amended.



     The Company has agreed to enter into a two-year non-exclusive consulting
agreement with the Representative, pursuant to which the Representative will act
as a financial consultant to the Company, commencing on the closing date of this
Offering. The total consulting fee of $72,000 will be payable, in full, on the
closing date of this Offering.



     The Company has agreed that for a period of thirteen months from the date
of this Prospectus it will not sell or otherwise dispose of any securities
without the prior written consent of the Representative, with the exception of
the grant of options and the issuance of shares issued upon the exercise of
options granted or to be granted under the Company's option plans and
outstanding warrants.


     The Underwriting Agreement provides for reciprocal indemnification between
the Company and the Underwriters against certain liabilities in connection with
the Registration Statement, including liabilities under the Securities Act.
Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company 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.


     The Company has agreed with the Representative that for a period of 24
months from the closing date of this Offering, the Representative may designate
an observer to the Board of Directors who will be entitled to attend and receive
notice of all meetings of the Board. The observer, who has not been determined,
will be reimbursed for out-of-pocket travel expenses incurred in attending such
meetings but will otherwise not be compensated by the Company.



     Upon the exercise of the Redeemable Warrants more than one year after the
Offering and to the extent not inconsistent with the guidelines of the National
Association of Securities Dealers Regulation, Inc., and the rules and
regulations of the Securities and Exchange Commission, the Company has agreed to
pay the Representative a commission equal to five percent of the exercise price
of the Redeemable Warrants. However, no compensation will be paid to the
Representative in connection with the exercise of the Redeemable Warrants if (a)
the market price of the underlying shares of Common Stock is lower than the
exercise price, (b) the Redeemable Warrants are exercised in an unsolicited
transaction, or (c) the Redeemable Warrants are held in any discretionary
accounts. In addition, unless granted an exemption by the Commission from
Regulation M promulgated under the Exchange Act, the Representative will be
prohibited from engaging in any market making activities or solicited brokerage
activities with regard to the Company's securities for a period of one or five
days before the solicitation of the exercise of any Redeemable Warrant or before
the exercise of any Redeemable Warrant based upon a prior solicitation, until
the later of the termination of such solicitation activity or the termination by
waiver or otherwise of any right the Representative or any other soliciting

     The Representative has advised the Company that, pursuant to Regulation M
under the Securities Act, some persons participating in this offering may engage
in transactions, including stabilizing bids, syndicate covering transactions or
the imposition of penalty bids, that may have the effect of stabilizing or
maintaining the market price of the Common Stock at a level above that which
might otherwise prevail in the open market. A "stabilizing bid" is a bid for or
the purchase of Common Stock on behalf of the underwriters for the purpose of
fixing or maintaining the price of the Common Stock. A "syndicate covering
transaction" is a bid for or the purchase of Common Stock on behalf of the
underwriters to reduce a short position incurred by the underwriters in
connection with this offering. A "penalty bid" is an arrangement permitting the
Representative to reclaim the selling concession otherwise accruing to an
underwriter or syndicate member in connection with this offering if the Common
Stock originally sold by such underwriter or syndicate member is purchased by
the Representative in a syndicate covering transaction and has therefore not
been effectively placed by such underwriter or syndicate member. The
Representative has advised the Company that such transactions may be effected on
the Nasdaq SmallCap Market or otherwise and, if commenced, may be discontinued
at any time.

the history and the prospects for the industry in which the Company competes,
the past and present operations of the Company, the future prospects of the
Company, the abilities of the Company's management, the earnings, net worth and
financial condition of the Company, the general condition of the securities
markets at the time of this Offering, and the prices of similar securities of
comparable companies.



                                 LEGAL MATTERS

                         REPORT OF INDEPENDENT AUDITORS


The Board of Directors and Stockholders
Implant Sciences Corporation

     We have audited the accompanying balance sheets of Implant Sciences
Corporation as of June 30, 1997 and 1998, and the related statements of
operations, stockholders' equity, and cash flows for each of the two years in
the period ended June 30, 1998. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit 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.
We believe that our audits provide a reasonable basis for our opinion.


     Since the date of completion of our audit of the accompanying financial
statements and initial issuance of our report thereon dated July 31, 1998, the
Company, as discussed in Note 1, has experienced an increase in costs and
decrease in its working capital as a result of delays in its planned equity
offering that adversely affect the Company's current results of operations and
liquidity. Note 1 describes management's plans to address these issues.


     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Implant Sciences Corporation
at June 30, 1997 and 1998, and the results of its operations and its cash flows
for each of the two years in the period ended June 30, 1998, in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS



        (INFORMATION AS OF MARCH 31, 1999 AND FOR THE NINE MONTHS ENDED


                MARCH 31, 1998 AND MARCH 31, 1999 IS UNAUDITED.)


1.  DESCRIPTION OF BUSINESS

     Implant Sciences Corporation is a provider of patented and proprietary
surface modification services to the medical device and semiconductor
industries. Ion implantation and thin film coating techniques are utilized to
enhance the surfaces for orthopedic implants (hip and knee total joint
replacements), to implant radioactive material into prostate seeds and coronary
stents, coatings on guidewires, stents and catheters for interventional
cardiology devices, and ion implantation of electronic dopants for the
semiconductor industry. The Company's principal markets are the orthopedic,
interventional cardiology and semiconductor markets.


     During 1998 and 1999, the Company incurred operating losses and utilized
significant cash to fund operations. During this time the Company increased its
cash expenditures to develop its new products, increase capacity and equipment
and increase sales and marketing capabilities in anticipation of FDA approval
for its radioactive prostate seed (which was obtained on May 26, 1999) and
radioactive stent products. The Company has been utilizing its credit facilities
and cash and cash equivalents to finance operations. In order to be better
positioned to achieve its strategic objectives, the Company is attempting to
obtain equity financing through an initial public offering of its common stock.



     The Company has experienced delays in completing its initial public
offering. Accordingly, the Company has implemented a number of programs to
reduce its use of cash, including operating expense reductions, while it
actively attempted to complete its initial public offering. The Company believes
that these programs will continue until such time as additional sources of
financing are obtained. Management of the Company has outlined and implemented a
plan of action to ensure that the Company has adequate sources of cash to meet
its working capital needs for at least the next twelve months. The key elements
of the plan are as follows:



     - Further operating expense reductions to eliminate certain expenditures
       which are not critically essential to achieving critical business
       objectives at this time (e.g., temporary personnel, use of outside
       consultants, discretionary spending).



     - Timing of new product development expenditures has been closely tied to
       timing of anticipated financing.



     - Continued pursuit of government research grants.



     - Pursuit of financing alternatives including bank financing, strategic
       alliances, and capital contributions by management.



     As a result of the above actions, management believes that its existing
cash resources and credit facilities should meet working capital requirements
over the next twelve months. However, unanticipated decreases in revenues,
increases in expenses or further delays in the process of obtaining equity
financing, may adversely impact the Company's cash position and require further
cost reductions.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)


INTERIM FINANCIAL STATEMENTS


     The financial information at March 31, 1999, and for the nine months ended
March 31, 1998 and 1999, is unaudited but includes all adjustments (consisting
only of normal recurring adjustments) which the Company considers necessary for
a fair presentation of the financial position at such date and of the operating
results and cash flows for these periods. The results of operations and cash
flows for the nine months ended March 31, 1998 and 1999 are not necessarily
indicative of results that may be expected for the entire year.


2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Cash and Cash Equivalents

     The Company considers any security with a maturity of 90 days or less to be
cash equivalents.

  Short-Term Investment

     Short-term investment consists of a U.S. Treasury bill with an original
maturity of six months. The investment is recorded at cost plus accrued interest
which approximates market value.

  Inventories

     Inventories consist of gold and other precious metal raw materials used in
the manufacturing process and are carried at the lower of cost (first-in,
first-out) or market.

  Property and Equipment and Capital Lease

     Property and equipment are stated at cost and depreciated using the
straight-line method over the estimated useful lives of the respective assets as
follows:

<TABLE>
<S>                                  <C>
Leasehold improvements.............  life of lease
Furniture and fixtures.............      5-7 years
Machinery and equipment............        7 years
</TABLE>

     Equipment under the capital lease is being amortized over the life of the
lease.

  Warranty Costs

     The Company accrues warranty costs in the period the related revenue is
recognized. Warranty costs are not material to operating results.

  Income Taxes

     The liability method is used to account for income taxes. Deferred tax
assets and liabilities are determined based on differences between the financial
reporting and income tax basis of assets and liabilities as well as net
operating loss and tax credit carryforwards and are measured using the enacted
tax rates and laws that will be in effect when the differences reverse. Deferred
tax assets may be reduced by a valuation allowance to reflect the uncertainty
associated with their ultimate realization.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)


  Patent Costs

     The costs to obtain patents are capitalized. The Company amortizes the cost
of patents ratably over their legal lives commencing with the month in which the
patents are issued. As of June 30, 1998, there were four patents issued.
Accumulated amortization at June 30, 1997 and 1998 was $10,627 and $15,699,
respectively.

  Concentrations of Credit Risk

     The Company grants credit to its customers, primarily large corporations in
the medical device and semiconductor industries. The Company performs periodic
credit evaluations of customer financial condition and does not require
collateral. Receivables are generally due within thirty days. Credit losses have
historically been minimal, which is consistent with management's expectations.

     The Company has three major customers which accounted for the following
annual revenue:

Company C.................................     148,000       175,000
</TABLE>

     Total accounts receivable at June 30, 1997 and 1998 for Company A was
approximately $223,000 and $138,000, respectively.

  Stock Based Compensation

     The Company accounts for its stock based compensation arrangements under
the provisions of APB Opinion No. 25, Accounting for Stock Issued to Employees,
rather than the alternative fair value accounting method provided for under FAS
No. 123, Accounting for Stock-Based Compensation. Under APB 25, when the
exercise price of options granted to employees and non-employee directors under
these plans equals the market price of the underlying stock on the date of
grant, no compensation expense is recorded.

  Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Actual results could differ from those estimates.

  Revenue Recognition

     Revenues are recognized at the time product is shipped. During fiscal 1996,
the Company was awarded a non-recurring, long-term, fixed price contract to
build one piece of customized manufacturing equipment, which was completed in
fiscal 1997. Revenues under this contract were recognized as costs were
incurred. The Company uses the percentage-of-completion method under the
contract and measures progress towards the completion using the cost-to-cost
method.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)


     Contract revenue under cost-sharing research and development agreements is
recognized as eligible research and development expenses are incurred. The
Company's obligation with respect to these agreements is to perform the research
on a best-efforts basis.

RESEARCH AND DEVELOPMENT COSTS

     All costs of research and development activities are expensed as incurred.
The Company performs research and development for itself and under contracts
with others, primarily the U.S. government. Company funded research and
development includes the excess of expenses over revenues on its commercial and
government research contracts and, therefore, is included in cost of product and
contract research revenues in the accompanying statement of operations.

     The Company funded and customer funded research and development costs for
1997 and 1998 were as follows:

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

     In June 1997, the Financial Accounting Standards Board (FASB) issued
Statement No. 130, Reporting Comprehensive Income and Statement No. 131,
Disclosures About Segments of an Enterprise and Related Information. Statement
No. 130 establishes standards for the reporting and display of comprehensive
income and its components. Statement No. 131 establishes standards for public
companies to report information about operating segments in financial
statements. It also establishes standards for related disclosures about products
and services, geographic areas, and customers. Statement 131 is effective for
financial statements for fiscal years beginning after December 15, 1997, and
therefore the Company will adopt the new requirements retroactively in 1999.
Under Statement 131 the Company believes that it will operate in one business
segment. Accordingly, the Company does not anticipate that the adoption of this
statement will have a significant effect on the Company's disclosures. Statement
130, which will be adopted in 1999, will not have a significant impact on the
Company's disclosures.

EARNINGS PER SHARE

     In 1998, the Company adopted the provisions of Statement of Financial
Accounting Standards No. 128, Earnings per Share. This Standard revises certain
methodology for computing earnings per common share (EPS) and requires the
reporting of two earnings per share figures: basic earnings per share and
diluted earnings per share. Basic earnings per common share are computed by
dividing net income by the weighted-average number of common shares outstanding.
Diluted earnings per share are computed by dividing net income by the sum of the
weighted-average number of common shares outstanding plus
                                      F-11

the dilutive effect of shares issuable through the exercise of stock options
(common stock equivalents).

     The shares used for basic earnings per common share and diluted earnings
per common share are reconciled as follows:

4.  RESEARCH AND DEVELOPMENT ARRANGEMENTS

     The Company is the recipient of several grants under the U.S. Government's
Small Business Innovative Research (SBIR) program. These grants are firm
fixed-priced contracts and generally range in length from six to nine months.
Revenues under such arrangements were approximately $12,000 and $308,000 for the
years ended June 30, 1997 and 1998, respectively.

     The Company also conducts research and development under cost-sharing
arrangements with its commercial customers. Revenues under such arrangements
were approximately $110,000 and $100,000 for the years ended June 30, 1997 and
1998, respectively.

5.  LONG-TERM CONTRACT

     During 1996, the Company entered into a one-time contract as a
subcontractor under a cost-plus fixed fee arrangement at a total contract price
of approximately $1,933,000, as amended.

     Amounts subject to retainage provisions were $13,500 at June 30, 1997. The
Company incurred general and administrative expenses relating to this contract
of approximately $88,000 for the year ended June 30, 1997. No general and
administrative expense relating to this contract were incurred for the year
ended June 30, 1998.

6.  LONG-TERM DEBT

     Maturities of long-term debt at June 30, 1998 are as follows:

                                           ========
</TABLE>

     The Company finances its operations utilizing a Revolving Credit Facility
("Credit Facility") and two Equipment Term Loans under a Loan Agreement with its
bank. Both borrowings under the Loan Agreement are cross-collateralized and
cross-defaulted. The Loan Agreement has a first lien on substantially all of the
Company's assets.

     The Credit Facility bears interest at the bank's base rate, plus 1% (9.5%
at June 30, 1998). Advances under the Credit Facility are limited to 70% of
qualifying accounts receivable and payable on demand. At June 30, 1998 the
Company had $300,000 available under the Credit Facility.

     In August 1997, the Company refinanced one of its Term Loans. The Term Loan
is payable in 48 monthly installments of $1,968, and matures September 30, 2001.
Interest is payable monthly at the same rate as the Credit Facility.

     In January 1998, the Company increased the amount available under its
Equipment Term Loan to $750,000. The Company may utilize this facility to
finance capital expenditures through October 1998. Principal repayments commence
November 1998 in sixty equal monthly installments. Interest is payable monthly
at 1% above the banks base rate commencing February 1998.

     Under the provisions of its Loan Agreement, the Company is required to
maintain compliance with certain financial covenants including debt service
coverage, minimum levels of net worth and restrictions on indebtedness. At June
30, 1998, the Company's debt service coverage and net worth was less than the
required amounts. The Company's bank

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)


has waived its rights under the Loan Agreement with respect to compliance with
these financial covenants at June 30, 1998. The Company complied with these
covenants at September 30, 1998. In December 1998, the Company's bank changed
its loan compliance requirements from a quarterly basis to an annual basis. The
bank now measures compliance annually, consistent with the Company's fiscal year
end. Accordingly, amounts payable under the Loan Agreement are classified as
long-term in the accompanying balance sheet.

7.  RELATED-PARTY TRANSACTIONS

     Accounts receivable from related parties as of June 30, 1998 consisted of a
loan of $137,500 to a principal shareholder. The interest rate on the loan,
which is unsecured, is six percent per annum. The entire amount of the principal
and accumulated interest will be due on December 9, 2003. This was accounted for
as a reduction of stockholders' equity.

     Between 1984 and 1994, two officers, Dr. Armini and Dr. Bunker, of the
Company, were not paid certain compensation. As a result, deferred compensation
of $811,825 was accrued by the Company as the services were rendered. In 1996
and 1997, payments of $213,252 and $119,000, respectively, were made to these
individuals. The remaining obligation was included in accrued compensation in
the June 30, 1997 balance sheet.

     During 1998, these individuals discharged the Company from the remaining
obligation of $461,000 which was recorded as an increase to Additional Paid-In
Capital, net of related tax effect of $186,500.


     In 1998, as consideration for terminating an agreement with an acting Chief
Financial Officer and resignation from the Company's board of directors, the
Company provided the following benefits to the consultant: (i) a $60,000 lump
sum cash payment; (ii) 12 additional payments of $4,125 per month; (iii)
warrants, with a three-year term, to purchase 86,640 shares of the Common Stock
of the Company at a price of $17.31 per share; (iv) 12,000 shares of the Common

</TABLE>



     The Company has adopted the disclosure provisions only of Statement of
Financial Accounting Standards No. 123, Accounting for Stock-based
Compensation(FAS 123). If the compensation cost for the option plans had been
determined based on the fair value at the grant date for grants in 1997 and
1998, consistent with the provisions of FAS 123, the pro forma net income for
1997 and 1998, would have decreased by $45,000 and $55,000 respectively, and by
$.01 per share and $.01 per share-diluted, respectively.


     The fair value of options and warrants issued at the date of grant were
estimated using the Minimum-Value method with the following weighted average
assumptions:

Risk free interest rate.............  6.9%-6.96%    5.55%-5.75%

</TABLE>

     The Company has never declared nor paid dividends and does not expect to do
so in the foreseeable future.

     The effects on 1997 and 1998 pro forma net income of expensing the
estimated fair value of stock options are not necessarily representative of the
effects on the results of operations for future years as the periods presented
include only two and three years, respectively, of option grants under the
Company's plans.

11.  ROYALTY AGREEMENT

     Under the terms of the sale of a former product line, the Company is
entitled to minimum annual royalties which aggregate $175,000 over four years.
During 1997 and 1998, the Company recognized approximately $75,000 and $44,000,
respectively, of royalties under this arrangement.

12.  401(k) PLAN

     The Company has a defined contribution retirement plan which contains a
401(k) program. All employees who are 21 years of age and who have completed one
year of service during which they worked at least 1,000 hours are eligible for
participation in the plan. The Company may make discretionary contributions. The
Company made contributions to the plan of $1,100 and $3,200 in 1997 and 1998,
respectively.

13.  SUBSEQUENT EVENTS


     In connection with a planned initial public offering of the Company's
Common Stock, the Company amended and restated its Articles of Organization in
September 1998. The amendment, among other things, included the following:



        - The Company's Board of Directors and Stockholders increased the
          authorized Common Stock to 20,000,000 shares.



        - The Company's Board of Directors and Stockholders authorized 5,000,000
          shares of Preferred Stock ($.10 par value). The Board of Directors was
          also authorized to issue the Preferred Stock in one or more series,
          and to fix the powers, designations, preferences and other rights,
          including dividend rights, conversion rights, voting rights,
          redemption terms and liquidation preferences without any further
          action by the Company's stockholders.



        - The Board of Directors and Stockholders declared a 7-for-1 stock split
          effected in the form of a stock dividend.


     Except for historical share amounts in the accompanying balance sheet and
statement of changes in stockholders' equity, the Company has restated all
historical share and per-share data to give retroactive effect to the 7-for-1
stock split effected in the form of a stock dividend. Upon distribution of the
shares the par value of the shares distributed will be transferred from
additional paid-in-capital to Common Stock.


     In addition, in September 1998, the Company adopted two new employee
benefit plans, the 1998 Incentive and Nonqualified Stock Option Plan ("Incentive
Plan") and the 1998 Employee Stock Purchase Plan ("Stock Purchase Plan"). Upon
the adoption of the 1998 Option Plan, the 1992 Option Plan was terminated. No
new stock options will be granted under the 1992 Option Plan, which has been
superseded by the 1998 Option Plan.



     The Incentive Plan provides for the grant of incentive stock options and
nonqualified stock options to officers and key employees for the purchase of up
to 1,680,000 shares of Common Stock. Options granted to purchase shares of
Common Stock are exercisable as determined by an appointed committee consisting
of two or more non-employee directors (Committee), expire within ten years from
date of grant and have an exercise price not less than the fair market value of
the Company's Common Stock on the date of grant. However, in the case of
qualified options, if an employee owns more than 10% of the voting power of all
classes of stock, the option granted will be at 110% of the fair market value of
the Company's Common Stock on the date of grant and will expire over a period
not to exceed five years.

                          IMPLANT SCIENCES CORPORATION



                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)



     In January 1999, the shares authorized and reserved for issuance under the
1998 Stock Option Plan were reduced from 1,680,000 shares to 240,000 shares of
authorized and unissued Common Stock.


     Under the terms of the Incentive Plan each non-employee director, upon
election and each subsequent reelection to the Board of Directors, shall
automatically receive a Nonqualified Option to purchase 2,000 shares of Common
Stock subject to the same terms and conditions referred to in the immediately
preceding paragraph.


     The 1998 Employee Stock Purchase Plan ("Purchase Plan") provides for the
issuance of 141,000 shares of common stock thereunder. Under the Purchase Plan,
eligible employees may purchase common shares at a price per share equal to 85%
of the lower of the fair market value of the common stock on the first or last
day of a one-year offering period. Participation in the offering period is
limited to $25,000 in any calendar year.



     On January 7, 1999, the Company entered into Loan Agreements with ten
employees. Pursuant to the terms of these Agreements, the Company loaned a total
of $137,500 to these ten employees for the purpose of exercising a total of
321,642 options to purchase Common Stock. The interest rate on the loans, which
are unsecured, is six percent per annum. The entire amount of the principal and
accumulated interest will be due within three years. This was accounted for as a
reduction of stockholders' equity.



     On June 8, 1999 the Company amended and restated its Articles of
Organization. The amendment, among other things, included the following:



        - The Board of Directors and Stockholders declared a 6-for-7 reverse
          stock split of its Common Stock.



        - The Board of Directors and Stockholders increased the authorized
          Common Stock, affected by the reverse stock split, from 17,142,857 to
          20,000,000 shares.



     Except for historical share amounts in the accompanying balance sheet and
statement of changes in stockholders' equity, the Company has restated all
historical share and per-share data to give retroactive effect to the 6-for-7
reverse stock split. Upon return of the shares the par value of the shares
returned will be transferred to additional paid-in-capital from Common Stock.

                     INFORMATION NOT REQUIRED IN PROSPECTUS


ITEM 24:  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Article VI.C. of the Company's Amended and Restated Articles of
Organization provides that a director shall not have personal liability to the
Company or its stockholders for monetary damages arising out of the director's
breach of fiduciary duty as a director of the Company, to the maximum extent
permitted by Massachusetts law. Section 13(b)(1 1/2) of Chapter 156B of the
Massachusetts General Laws provides that the articles of organization of a
corporation may state a provision eliminating or limiting the personal liability
of a director to a corporation or its stockholders for monetary damages for
breach of fiduciary duty as a director, provided, however, that such provision
shall not eliminate or limit the liability of a director (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under sections 61 or 62 of Chapter 156B of the
Massachusetts General Laws, which relate to liability for unauthorized
distributions and loans to insiders, respectively, or (iv) for any transaction
from which the director derived an improper personal benefit.

     Article VI.D. of the Company's Amended and Restated Articles of
Organization further provides that the Company shall, to the fullest extent
authorized by Chapter 156B of the Massachusetts General Laws, indemnify each
person who is, or shall have been, a director or officer of the Company or who
is or was a director or employee of the Company and is serving, or shall have
served, at the request of the Company, as a director or officer of another
organization or in any capacity with respect to any employee benefit plan of the
Company, against all liabilities and expenses (including judgments, fines,
penalties, amounts paid or to be paid in settlement, and reasonable attorneys'
fees) imposed upon or incurred by any such person in connection with, or arising
out of, the defense or disposition of any action, suit or other proceeding,
whether civil or criminal, in which they may be involved by reason of being or
having been such a director or officer or as a result of service with respect to
any such employee benefit plan. Section 67 of Chapter 156B of the Massachusetts
General Laws authorizes a corporation to indemnify its directors, officers,
employees and other agents unless such person shall have been adjudicated in any
proceeding not to have acted in good faith in the reasonable belief that such
action was in the best interests of the corporation or, to the extent such
matter related to service with respect to an employee benefit plan, in the best
interests of the participants or beneficiaries of such employee benefit plan.

     The effect of these provisions would be to permit indemnification by the
Company for, among other liabilities, liabilities arising out of the Securities
Act of 1933, as amended (the "Securities Act").

     Section 67 of Chapter 156B of the Massachusetts General Laws also affords a
Massachusetts corporation the power to obtain insurance on behalf of its
directors and officers against liabilities incurred by them in those capacities.
The Company intends to procure a directors and officers liability and company
reimbursement liability insurance policy that (i) insures directors and officers
of the Company against losses (above a deductible amount) arising from certain
claims made against them by reason of certain acts done or attempted by such
directors or officers and (ii) insures the Company against losses (above a
deductible amount) arising from any such claims, but only if the Company

                                      II-1
<PAGE>   85

is required or permitted to indemnify such directors or officers for such losses
under statutory or common law or under provisions of the Company's Amended and
Restated Articles of Organization or Amended and Restated By-Laws.

     Reference is hereby made to Section 7 of the Underwriting Agreement between
the Company and the Underwriters, filed as Exhibit 1.1 to this Registration
Statement, for a description of indemnification arrangements between the Company
and the Underwriters.

ITEM 26:  RECENT SALES OF UNREGISTERED SECURITIES.

     The following information is furnished with regard to all securities sold
by the Company within the past three years which were not registered under the
Securities Act. The share numbers set forth below have been adjusted to reflect
the 7-for-1 stock split effected by the Company on September 9, 1998.


          (a) On July 1, 1998, as partial consideration for terminating an
     agreement with the acting Chief Financial Officer to the Company and his
     resignation from the Company's board of directors, the Company provided the
     following: (i) 12,000 shares of the Common Stock of the Company; and (ii)
     warrants, with a three-year term, to purchase 86,640 shares of the Common
     Stock of the Company at a price of $17.31 per share. In addition, as part
     of this individual's original agreement, dated October 31, 1997, he was
     also provided warrants, with a three year term, to purchase 9,000 shares of
     Common Stock of the Company at a price of $1.51 per share. The Company
     granted piggyback registration rights to this individual in any public
     offering after the initial public offering of the Common Stock.



          (b) On June 17, 1997, NAR Holding Corporation exercised its preemptive
     rights to purchase 301,668 shares of Common Stock of the Company at a price
     of $.49 per share.


     The issuances described in this Item 26 were made in reliance upon the
exemption from registration set forth in Section 4(2) of the Securities Act
relating to sales by an issuer not involving any public offering. None of the
foregoing transactions involved a

                                      II-2
<PAGE>   86

distribution or public offering. No underwriters were engaged in connection with
the foregoing issuances of securities, and no underwriting discounts or
commissions were paid.

ITEM 28.  UNDERTAKINGS.

     The undersigned registrant hereby undertakes to provide to the underwriter
at the closing specified in the underwriting agreements certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Act") may be permitted to directors, officers and controlling
persons of the small business issuer pursuant to the foregoing provisions, or
otherwise, the small business issuer 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
the small business issuer of expenses incurred or paid by a director, officer or
controlling person of the small business issuer in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the small business
issuer will, unless in the opinion of its
                                      II-5
<PAGE>   89

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 Act and will be governed by the final
adjudication of such issue.

     The undersigned registrant hereby undertakes to:

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

             (i) Include any prospectus required by Section 10(a)(3) of the
        Securities Act;

             (ii) Reflect in the prospectus any facts or events which,
        individually or together, represent a fundamental change in the
        information in the registration statement; and

             (iii) Include any additional or changed material information on 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 such securities at that time to be the initial
     bona fide offering.

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

          (4) 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 small business issuer under Rule 424(b)(1) or
     (4) of 497(h) under the Securities Act as part of this registration
     statement as of the time the Commission declared it effective.

          (5) 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 that offering of the securities at that time as the initial
     bona fide offering of those securities.

                          AGREEMENT AMONG UNDERWRITERS


                                                                          , 1999
Westport Resources Investment Services, Inc.
315 Post Road West
Westport, CT 06880


GENTLEMEN:

    We wish to confirm as follows the agreement among you, the undersigned and
the other members of the Underwriting Group named in Schedule I to the
Underwriting Agreement, as it is to be executed (all such parties being herein
called the "Underwriters"), with respect to the purchase by the Underwriters
severally from Implant Sciences Corporation ("Company") of shares of Common
Stock and Redeemable Warrant ("Securities") set forth in Schedule I to the
Underwriting Agreement. The number of Securities to be purchased by each
Underwriter from the Company shall be determined in accordance with Section 2 of
the Underwriting Agreement. It is understood that changes may be made in those
who are to be Underwriters and in the respective numbers of Securities to be
purchased by them, but that the Underwriting Agreement will not be changed
without our consent, except as provided herein, and in the Underwriting
Agreement. The obligations of the Underwriters to purchase the number of
Securities set opposite their respective names in Schedule I to the Underwriting
Agreement, are herein called their "underwriting obligations." The number of
Securities set opposite our name in said Schedule I, are herein called "our
Securities." For purposes of this Agreement the following definitions shall be
applicable:

      (a) "Manager's Concession" shall be the compensation to you for acting as
Manager as provided in Paragraph 1 of not less than     percent (%) of the
underwriting discount. The Manager's Concession shall include the right to a
portion of the warrants to be issued pursuant to the Underwriting Agreement and,
the right to the nonaccountable expenses to be paid pursuant to the Underwriting
Agreement.

      (b) "Underwriting Group Concession" shall mean compensation to members of
the Underwriting Group for assuming the underwriting risk and shall be not less
than    percent (%) of the underwriting discount.

      (c) "Dealer's Concession" shall mean compensation to Dealers, who are
members of the Selling Group and shall, as to Dealers who have executed an
agreement with you, be not less than    percent (%) of the underwriting
discount.

      (d) "Dealer's Reallowance Concession" shall mean the compensation allowed
Dealers by Underwriters other than you and shall be one-half (1/2) of the
Dealer's Concession.

      (e) It is contemplated that the underwriting discount will be ten percent
(10%) of the offering price. You, in your absolute discretion, shall determine,
within the foregoing limitations, the precise allocation of the underwriting
discount and shall notify us of same at least twenty-four (24) hours prior to
the execution of the Underwriting Agreement.



1. Authority and Compensation of Representative. We hereby authorize you, as our
Representative and on our behalf, (a) to enter into an agreement with the
Company substantially in the form attached hereto as Exhibit A ("Underwriting
Agreement"), but with such changes therein as in your judgment are not
materially adverse to the
<PAGE>   2
Underwriters, (b) to exercise all the authority and discretion vested in the
Underwriters and in you by the provisions of the Underwriting Agreement, and (c)
to take all such action as you, in your discretion, may deem necessary or
advisable in order to carry out the provisions of the Underwriting Agreement and
this Agreement and the sale and distribution of the Securities, provided,
however, that the time within which the Registration Statement is required to
become effective pursuant to the Underwriting Agreement will not be extended
more than forty-eight (48) hours without the approval of a majority in interest
of the Underwriters (including you). We authorize you, in executing the
Underwriting Agreement on our behalf, to set forth in Schedule I of the
Underwriting Agreement as our commitment to purchase the number of Securities
(which shall not be substantially in excess of the number of Securities included
in your invitation to participate unless we have agreed otherwise) included in a
wire, telex, or similar means of communication transmitted by you to us at least
twenty-four (24) hours prior to the commencement of the offering as our
finalized underwriting participation.

As our share of the compensation for your services hereunder, we will pay you,
and we authorize you to charge to our account, a sum equal to the Manager's
Concession.

    2. Public Offering. A public offering of the Securities is to be made, as
herein provided, as soon after the Registration Statement relating thereto shall
become effective as in your judgment is advisable. The Securities shall be
initially offered to the public at the public offering price of $      per share
and $      per Redeemable Warrant. You will advise us by telegraph or telephone
when the Securities shall be released for offering. We authorize you as
Representative of the Underwriters, after the initial public offering, to vary
the public offering price, in your sole discretion, by reason of changes in
general market conditions or otherwise. The public offering price of the
Securities at any time in effect is herein called the "Offering Price."

    We hereby agree to deliver all preliminary and final Prospectuses as
required for compliance with the provisions of Rule 15c2-8 under the Securities
Exchange Act of 1934 and Section 5(b) of the Securities Act of 1933. You have
heretofore delivered to us such preliminary Prospectuses as have been requested
by us, receipt of which is hereby acknowledged, and will deliver such final
Prospectuses as will be requested by us.

    3. Offering to Dealers and Group Sales. We authorize you to reserve for
offering and sale, and on our behalf to sell, to institutions or other retail
purchasers (such sales being herein called "Group Sales") and to dealers
selected by you (such dealers being herein called the "Dealers") all or any part
of our Securities as you may determine. Such sales of Securities, if any, shall
be made (i) in the case of Group Sales, at the Offering Price, and (ii) in the
case of sales to Dealers, at the Offering Price less the Dealer's Concession.

    Any Group Sales shall be as nearly as practicable in proportion to the
underwriting obligations of the respective Underwriters. Any sales to Dealers
made for our account shall be as nearly as practicable in the ratio that the
Securities reserved for our account for offering to Dealers bears to the
aggregate of all Securities of all Underwriters, including you, so reserved. On
any Group Sales or sales to Dealers made by you on our behalf, we shall be
entitled to receive only the Underwriter's Concession.

    You agree to notify us not less than twenty-four (24) hours prior to the
commencement of the public offering as to the number of Securities, if any,
which we may retain for direct sale. Prior to the termination of this Agreement,
you may reserve for offering and sale, as herein before provided, any Securities
remaining unsold theretofore retained by us and we may, with your consent,
retain any Securities remaining unsold theretofore reserved by you. Sales to
Dealers shall be made under a Selected Dealers Agreement, attached hereto as
Exhibit B and by this reference incorporated herein. We authorize you to
determine the form and manner of any communications with Dealers, and to make
such changes in the Selected Dealers Agreement, as you may deem appropriate. In
the event that there shall be any such agreements with Dealers, you are
authorized to act as managers thereunder, and we agree, in such event, to be
governed by the terms and conditions of such agreements. Each Underwriter agrees
that it will not offer any of the Securities for sale at a price below the
Offering Price or allow any concession therefrom, except as herein otherwise
provided. We, as to our Securities, may enter into agreements with Dealers, but
any Dealer's Reallowance Concession shall not exceed half of the Dealer's
Concession.


                                       2
<PAGE>   3
It is understood that any person to whom an offer may be made, as herein before
provided, shall be a member of the National Association of Securities Dealers,
Inc. ("NASD") or dealers or institutions with their principal place of business
located outside of the United States, its territories or possessions, and who
are not eligible for membership under Section 1 of the Bylaws of the NASD who
agree to make no sales within the United States, its territories or possessions,
or to persons who are nationals thereof, or residents therein, and, in making
sales, to comply with the NASD's Rules of Fair Practice.

      We authorize you to determine the form and manner of any public
advertisement of the Securities.

    Nothing in this Agreement contained shall be deemed to restrict our right,
subject to the provisions of this Section 3, to offer our Securities prior to
the effective date of the Registration Statement, provided, however, that any
such offer shall be made in compliance with any applicable requirements of the
Securities Act of 1933 and the Securities Exchange Act of 1934 and the rules and
regulations of the Securities and Exchange Commission thereunder and of any
applicable state securities laws.

    4. Repurchases in the Open Market. Any Securities sold by us (otherwise than
through you) which, prior to the termination of this Agreement, or such earlier
date as you may determine, shall be contracted for or purchased in the open
market by you on behalf of any Underwriter or Underwriters, shall be repurchased
by us on demand at a price equal to the cost of such purchase plus commissions
and taxes, if any, on redelivery. Any Securities delivered on such repurchase
need not be the identical Securities originally sold by us. In lieu of delivery
of such Securities to us, you may (i) sell such Securities in any manner for our
account and charge us with the amount of any loss or expense, or credit us with
the amount of any profit, less any expense, resulting from such sale, or (ii)
charge our account with an amount not in excess of the concession to Dealers
on such Securities.

    5. Delivery and Payment. We agree to deliver to you, at or before 9:00 A.M.,
New York, New York Time, on the Closing Date referred to in the Underwriting
Agreement, at your office, a certified or bank cashier's check payable to your
order for the offering price of the Securities less Dealer's Concession of the
Securities which we retained for direct sale by us, the proceeds of which check
shall be delivered to you, in the manner provided in the Underwriting Agreement,
to or for the account of the Company against delivery of certificates for such
Securities to you for our account. You are authorized to accept such delivery
and to give receipts therefor. You may advance funds for Securities which have
been sold or reserved for sale to retail purchasers or Dealers for our account.
If we fail (whether or not such failure shall constitute a default hereunder) to
deliver to you, or you fail to receive, our check and/or payment for sales made
by you for our account for the Securities which we have agreed to purchase, you,
individually and not as Representative of the Underwriters, are authorized (but
shall not be obligated) to make payment, in the manner provided in the
Underwriting Agreement, to or for the account of the Company for such Securities
for our account, but any such payment by you shall not relieve us of any of our
obligations under the Underwriting Agreement or under this Agreement and we
agree to repay you on demand the amount so advanced for our account.

         We also agree on demand to take up and pay for or to deliver to you
funds sufficient to pay for at cost any Securities of the Company purchased by
you for our account pursuant to the provisions of Section 9 hereof, and to
deliver to you on demand any Securities sold by you for our account, pursuant to
any provision of this Agreement.

         We authorize you to deliver our Securities, and any other Securities
purchased by you for our account pursuant to the provisions of Section 9 hereof,
against sales made by you for our account pursuant to any provision of this
Agreement.

    Upon receipt by you of payment for the Securities sold by us and/or through
you for our account, you will remit to us promptly an amount equal to the
Underwriter's Concession on such Securities. You agree to cause to be delivered
to us, as soon as practicable after the Closing Date referred to in the
Underwriting Agreement, such part of our Securities purchased on such Closing
Date as shall not have been sold or reserved for sale by your for our account.

    In case any Securities reserved for sale in Group Sales or to Dealers shall
not be purchased and paid for in due course as contemplated hereby, we agree to
accept delivery when tendered by you of any Securities so reserved for our
account and not so purchased and pay you the offering price less the Dealer's
and Underwriter's Concessions.



                                       3

    6. Authority to Borrow. We authorize you to advance your funds for our
account (charging current interest rates) and to arrange loans for our account
for the purpose of carrying out this Agreement, and in connection therewith to
execute and deliver any notes or other instruments, and to hold, or pledge as
security therefor, all or any part of our Securities of the Company purchased
hereunder for our account. Any lending bank is hereby authorized to accept your
instructions as Representative in all matters relating to such loans. Any part
of our Securities held by you, may be delivered to us for carrying purposes, and
if so delivered, will be redelivered to you upon demand.

    7. Allocation of Expense and Liability. We authorize you to charge our
account with, and we agree to pay (a) all transfer taxes on sales made by you
for our account, except as herein otherwise provided, and (b) our proportionate
share (based on our underwriting obligations) of all expenses in excess of those
reimbursed by the Company incurred by you in connection with the purchase,
carrying and distribution, or proposed purchase and distribution, of the
Securities and all other expenses arising under the terms of the Underwriting
Agreement or this Agreement. Your determination of all such expenses and your
allocation thereof shall be final and conclusive. Funds for our account at any
time in your hands as our Representative may be held in your general funds
without accountability for interest. As soon as practicable after the
termination of this Agreement, the net credit or debit balance in our account,
after proper charge and credit for all interim payments and receipts, shall be
paid to or paid by us, provided, however, that you, in your discretion, may
reserve from distribution an amount to cover possible additional expenses
chargeable to the several Underwriters.

    8. Liability for Future Claims. Neither any statement by you, as
Representative of the Underwriters, of any credit or debit balance in our
account nor any reservation from distribution to cover possible additional
expenses relating to the Securities shall constitute any representation by you
as to the existence or nonexistence of possible unforeseen expenses or
liabilities of or charges against the several Underwriters. Notwithstanding the
distribution of any net credit balance to us or the termination of this
Agreement, or both, we shall be and remain liable for, and will pay on demand,
(a) our proportionate share (based on our underwriting obligations) of all
expenses and liabilities which may be incurred by, or for the accounts of the
Underwriters, including any liability which may be incurred by the Underwriters
or any of them, and (b) any transfer taxes paid after such settlement on account
of any sale or transfer for our account.

    9. Stabilization. We authorize you, until the termination of this Agreement,
(a) to make purchases and sales of the Securities, in the open market or
otherwise, for long or short account, and on such terms, and at such prices as
you in your discretion may deem desirable, (b) in arranging for sales of
Securities, to overallot, and (c) either before or after the termination of this
Agreement, to cover any short position incurred pursuant to this Section 9;
subject, however, to the applicable rules and regulations of the Securities and
Exchange Commission under the Securities Exchange Act of 1934. All such
purchases, sales and overallotments shall be made for the accounts of the
several Underwriters as nearly as practicable in proportion to their respective
underwriting obligations; provided, however, that our net position resulting
from such purchases and sales and overallotments shall not at any time exceed,
either for long or short account, fifteen percent (15%) of the number of
Securities agreed to be purchased by us.

    If you engage in any stabilizing transactions as representative of the
underwriters, you shall promptly notify us of that fact and in like manner you
agree to promptly notify and file with us any stabilizing transaction in
accordance with the requirements of Rule 17a-2(d) under the Securities Exchange
Act of 1934.


We agree to advise you from time to time, upon request, until the settlement of
accounts hereunder, of the number of Securities at the time retained by us
unsold, and we will upon request sell to you, for the accounts of one or more of
the several Underwriters, such number of our unsold Securities as you may
designate, at the Offering Price less such amount, not in excess of the
concession to Dealers, as you may determine.


                                       4
<PAGE>   5
    10. Open Market Transactions. We agree that, except with your consent and
except as herein provided upon advice from you, we will not make purchases or
sales on the open market or otherwise, or attempt to induce others to make
purchases or sales, either before or after the purchase of the Securities, and
prior to the completion (as defined in Regulation M of the Securities Exchange
Act of 1934) of our participation in the distribution, we will otherwise comply
with Regulation M. Nothing in this Section 10 contained shall prohibit us from
acting as broker or agent in the execution of unsolicited orders of customers
for the purchase or sale of any securities of the Company.

    11. Blue Sky. Prior to the initial offering by the Underwriters, you will
inform us as to the states under the respective securities or Blue Sky laws of
which it is believed that the Securities have been qualified or are exempt for
sale, but you do not assume any responsibility or obligation as to the accuracy
of such information or as to the right of any Underwriter or Dealer to sell the
Securities in any jurisdiction. We will not sell any Securities in any other
state or jurisdiction and we will not sell Securities in any state or
jurisdiction unless we are qualified or licensed to sell securities in such
state or jurisdiction. We authorize you, if you deem it unadvisable in arranging
sales of Securities for our account hereunder, to sell any of our Securities to
any particular Dealer, or other buyer, because of the securities or Blue Sky
laws of any jurisdiction, to sell our Securities to one or more other
Underwriters at the Offering Price less, in the case of a sale to any Dealer,
such amount, not in excess of the concession to Dealers thereon, as you may
determine. The transfer tax on any such sales among Underwriters shall be
treated as an expense and charged to the respective accounts of the several
Underwriters, in proportion to their respective underwriting obligations.

    12. Default by Underwriters. Default by one or more Underwriters, in respect
to their obligations under the Underwriting Agreement shall not release us from
any of our obligations. In case of such default by one or more Underwriters, you
are authorized to increase, pro rata, with the other nondefaulting Underwriters,
the number of defaulted Securities which we shall be obligated to purchase from
the Company, provided, however, that the aggregate amount of all such increases
for all Underwriters shall not exceed ten percent (10%) of such Securities, and,
if the aggregate number of the Securities not taken up by such defaulting
Underwriters exceeds such ten percent (10%), you are further authorized, but
shall not be obligated, to arrange for the purchase by other persons, who may
include yourselves, of all or a portion of the Securities not taken up by such
Underwriters. In the event any such increases or arrangements are made, the
respective numbers of Securities to be purchased by the nondefaulting
Underwriters and by any such other person or persons shall be taken as the basis
for the underwriting obligations under this Agreement, but this shall not in any
way affect the liability of any defaulting Underwriters to the other
Underwriters for damages resulting from such default.

    In the event of default by one or more Underwriters in respect of their
obligations under this Agreement to take up and pay for any Securities purchased
by your for their respective accounts, pursuant to Section 9 hereof, or to
deliver any such Securities sold or overallotted by you for their respective
accounts pursuant to any provisions of this Agreement, and to the extent that
arrangements shall not have been made by you for other persons to assume the
obligations of such defaulting Underwriter or Underwriters, each nondefaulting
Underwriter shall assume its proportionate share of the aforesaid obligations of
each such defaulting Underwriter without relieving any such Underwriter of its
liability therefor.

    13. Termination of Agreement. Unless earlier terminated by you, the
provisions of Sections 2, 3, 4, 6, 9 and 10 of this Agreement shall, except as
otherwise provided therein, terminate thirty (30) full business days after the
effective date of the Registration Statement herein referred to, but may be
extended by you for an additional period or periods not exceeding thirty (30)
full business days in the aggregate. You may, however, terminate this Agreement,
or any provisions hereof, at any time by written or telegraphic notice to us.

    14. General Position of the Representative. In taking action under this
Agreement, you shall act only as agent of the several Underwriters. Your
authority as Representative of the several Underwriters shall include the taking
of


                                       5
<PAGE>   6
such action as you may deem advisable in respect of all matters pertaining to
any and all offers and sales of the Securities, including the right to make any
modifications which you consider necessary or desirable in the arrangements with
Dealers or others. You shall be under no liability for or in respect of the
value of the Securities or the validity or the form thereof, the Registration
Statement, the Prospectus, the Underwriting Agreement, or other instruments
executed by the Company or others of any agreement on its or their part; nor
shall you, as such Representative or otherwise, be liable under any of the
provisions hereof, or for any matters connected herewith, except for want of
good faith, and except for any liability arising under the Securities Act of
1933; and no obligation not expressly assumed by you as such Representative
herein shall be implied from this Agreement. In representing the Underwriters
hereunder, you shall act as the representative of each of them respectively.
Nothing herein contained shall constitute the several Underwriters partners with
you or with each other, or render any Underwriter liable for the commitments of
any other Underwriter, except as otherwise provided in Section 12 hereof. The
commitments and liabilities of each of the several Underwriters are several in
accordance with their respective underwriting obligations and are not joint.

    15. Acknowledgment of Registration Statement, etc. We hereby confirm that we
have examined the Registration Statement (including all amendments thereto)
relating to the Securities as heretofore filed with the Securities and Exchange
Commission, that we are familiar with the amendment(s) to the Registration
Statement and the final form of Prospectus proposed to be filed, that we are
willing to accept the responsibilities of an underwriter thereunder, and that we
are willing to proceed as therein contemplated. We further confirm that the
statements made under the heading "Underwriting" in such proposed final form of
Prospectus are correct and we authorize you so to advise the Company on our
behalf. We understand that the aforementioned documents are subject to further
change and that we will be supplied with copies of any amendment or amendments
to the Registration Statement and of any amended Prospectus promptly, if and
when received by you, but the making of such changes and amendments shall not
release us or affect our obligations hereunder or under the Underwriting
Agreement.

    16. Indemnification. Each Underwriter, including you, agrees to indemnify
and hold harmless each other Underwriter and each person who controls any other
Underwriter within the meaning of Section 15 of the Securities Act of 1933, as
amended, to the extent of their several commitments under the Underwriting
Agreement and upon the terms that such Underwriter agrees to indemnify and hold
harmless the Company as set forth in Section 7 of the Underwriting Agreement.
The Agreement contained in this Section 16 shall survive any termination of this
Agreement Among Underwriters.

    17. Capital Requirements. We confirm that our ratio of aggregate
indebtedness to net capital is such that we may, in accordance with and pursuant
to Rule 15c-1, promulgated by the Securities and Exchange Commission under the
Securities Exchange Act of 1934, agree to purchase the number of Securities we
may be obligated to purchase under any provision of the Underwriting Agreement
or this Agreement.

    18. Miscellaneous. We have transmitted herewith a completed Underwriters'
Questionnaire on the form thereof supplied by you. Any notice hereunder from you
to us or from us to you shall be deemed to have been duly give if sent by
registered mail, telegram, teletype, telex, telecopier, graphic scan, or other
written form of telecommunication to us at our address as set forth in the
Underwriting Agreement, or to you at the address set forth on the first page of
this Agreement.

         You hereby confirm that you are registered as a broker-dealer with the
United States Securities and Exchange Commission and that you are a member of
the NASD and we confirm that we are either a member of the NASD or a foreign
broker-dealer not eligible for membership under Section I of the Bylaws of the
NASD, who agrees to make no sales within the United States, its territories or
possessions, or to persons who are nationals thereof or residents therein, and,
in making sales, to comply with the requirements of the NASD's Interpretation
with Respect to Free Riding and Withholding, and with Sections 2730, 2740, and
2420 to the extent applicable to foreign nonmember brokers or dealers, and
Section 2750 of the NASD's Rules of Fair Practice.

    We will comply with all applicable federal laws, the laws of the states or
other jurisdictions concerned and the Rules and Regulations of the NASD,
including, but not limited to, Section 2740 of the Rules of Fair Practice.

    This instrument may be signed by the Underwriters in various counterparts

Underwriters and shall become effective as between us at such time as you shall
have confirmed same by returning an executed copy to us, and thereafter, as to
us and the other Underwriters, upon execution by them of counterparts which are
confirmed by you. In no event, however, shall we have any liability under this

    Westport Resources Investment Services, Inc.
    315 Post Road West
    Westport, Connecticut 06880



    Dear Sirs:

    Implant Sciences Corporation a Massachusetts corporation (the "Company"),
proposes to issue and sell to the several Underwriters named in Schedule I
hereto, who are acting severally and not jointly, (the "Underwriters"), one
million units (1,000,000), (the "Units") each Unit consisting of one share of
common stock of the Company and one redeemable common stock purchase warrant
(the "Warrant(s)") (the Units, Common Stock and Warrants collectively referred
to as the "Securities"). The Company hereby confirms the agreement made by it
with respect to the purchase of the Securities by the Underwriter (s), which
Securities are more fully described in the Registration Statement referred to
below. Westport Resources Investment Services, Inc. is referred to herein as the
"Representative" and along with Schneider Securities, Inc. and Weatherly
Securities Corporation as the "Underwriters".

    You have advised the Company that the Underwriters desire to act on a firm
commitment basis to publicly offer and sell the Securities for the Company and
that you are authorized to execute this Agreement. The Company confirms the
agreement made by it with respect to the relationship with the Underwriters as
follows:

1.       Filing of Registration Statement with S.E.C. and Definitions. A
         Registration Statement and Prospectus on Form SB-2 (File No. 333-64499)
         with respect to the Securities has been carefully and accurately
         prepared by the Company in conformity with the requirements of the
         Securities Act of 1933, as amended (the "Act"), and the published rules
         and regulations (the "Rules and Regulations") thereunder or under the
         Securities Exchange Act of 1934, as amended (the "Exchange Act") and
         has been declared effective with the Securities and Exchange Commission
         (the "Commission") on April 30, 1999 and in such other states that the
         Underwriter deemed necessary in its discretion to so file to permit a
         public offering and trading thereunder. Such registration statement,
         including the prospectus, Part II, and all financial schedules and
         exhibits thereto, as amended at the time when it shall become
         effective, is herein referred to as the "Registration Statement," and
         any prospectus included as part of the Registration Statement on file
         with the Commission that discloses all the information that was omitted
         from the prospectus on the effective date pursuant to Rule 430A of the
         Rules and Regulations with any changes contained in any prospectus
         filed with the Commission by the Company with the Underwriters consent
         after the effective date of the Registration Statement, is herein
         referred to as the "Final Prospectus." The prospectus included as part
         of the Registration Statement of the Company and in any amendments
         thereto prior to the post-effective date of the Registration Statement
         is referred to herein as a "Second Preliminary Prospectus."




2.       Discount, Delivery, and Sale of the Securities
<PAGE>   2
       (a) Subject to the terms and conditions of this Agreement, and on the
basis of the representations, warranties, and agreements herein contained, the
Company agrees to sell to, and the Underwriters agree to buy from the Company at
a purchase price of $ 6.75 per Unit before any underwriter expense allowances,
an aggregate of 1,000,000 Units on a firm commitment basis the "Initial
Securities". It is understood that the Underwriters propose to reoffer the
Securities to be purchased hereunder to the public upon the terms and conditions
set forth in the Registration Statement, after the post-effective Registration
Statement becomes effective.

       (b) Delivery of the Securities against payment of the purchase price
therefor by certified or official bank check or checks or wire transfer in
next-day funds, payable to the order of the Company shall take place at the
offices of the clearing broker for the Representative at New York City, within
three (3) business day after the Securities are first traded (or such other
place as may be designated by agreement between you and the Company) at 11:00
A.M., New York time or such time and date as you and the Company may agree upon
in writing, such time and date of payment and delivery for the Securities being
herein called the "Initial Closing Date."

    The Company will make the certificates for the Units and for the shares of
Common Stock and Warrants to be purchased by the Underwriters hereunder
available to the Underwriter for inspection and packaging at least two (2) full
business days prior to the Initial Closing Date. The Unit certificates shall be
in such names and denominations as the Underwriter may request to the Company in
writing at least four (4) full business days prior to any Closing Date.

    (c) In addition, subject to the terms and conditions of this Agreement and
on the basis of the representations, warranties and agreements herein contained,
the Company grants an option to the Underwriters to purchase up to an additional
150,000 Units ("Option Securities") at the same terms as the Underwriters shall
pay for the Initial Securities being sold by the Company pursuant to the
provisions of Section 2(a) hereof. This option may be exercised from time to
time, for the purpose of covering overallotments, within forty-five (45) days
after (i) the effective date of the Registration Statement if the Company has
elected not to rely on Rule 430A under the Rules and Regulations or (ii) the
date of this Agreement if the Company has elected to rely upon Rule 430A under
the Rules and Regulations, upon written notice by the Underwriter setting forth
the number of Option Securities as to which the Underwriter is exercising the
option and the time and date at which such certificates are to be delivered.
Such time and date shall be determined by the Underwriter but shall not be
earlier than four (4) nor later than ten (10) full business days after the date
of the exercise of said option. Nothing herein shall obligate the Underwriter to
make any overallotment.

     (d) Definitive certificates in negotiable form for the Securities to be
purchased by the Underwriter(s) hereunder will be delivered at the closing by
the Company to the Underwriters against payment of the purchase price by the
Underwriters by certified or bank cashier's checks or wire transfer in funds
payable to the order of the Company.

    (e) The information set forth under "Underwriting" in any second preliminary
prospectus and Prospectus relating to the Securities and the information set
forth in the front cover page, and within the prospectus concerning
stabilization and over-allotment by the Underwriters, and (insofar as such
information relates to the Underwriters) constitutes the only information
furnished by the Underwriters to the Company for inclusion therein, and you
represent and warrant to the Company that the statements made therein are
correct.

    (f) On the Initial Closing Date, the Company shall issue and sell to the
Underwriters, warrants (the "Underwriters' Warrants") at a purchase price of
$.001 per Underwriters' Warrant, which shall entitle the holders thereof to
purchase an aggregate of 100,000 Shares of Common Stock and 100,000 Redeemable
Warrants. The shares of Common Stock and Redeemable Warrants issuable upon the
exercise of the Underwriters' Warrants are hereafter referred to as the
"Underwriter's Securities" or "Underwriter's Warrants." The shares of Common
Stock issuable upon exercise of the redeemable warrants are hereinafter referred
to collectively as the "Underwriters Warrant Shares". The Underwriters' Warrants
for all securities shall be exercisable for a period of four (4) years
commencing one (1) year from the effective date of the Registration Statement at
a price equaling one hundred sixty percent (160%) of the initial public offering
price of the Securities. The form of Underwriters' Warrant shall be
substantially in the form filed as an Exhibit to the Registration Statement.
Payment for the Underwriters' Warrants shall be made on the Initial Closing
Date.

3. Representations and Warranties of the Company.

       (a) The Company represents and warrants to you as follows:

       (i) The Company has prepared and filed with the Commission a registration
statement, and an amendment or amendments thereto, on Form SB-2 (No. 333-64499),
including any related Preliminary Prospectus for the registration of the
Securities, the Underwriters' Warrant and the Underwriters' Warrant Shares
(sometimes referred to herein collectively as the "Registered Securities"),
under the Act, which registration statement and amendment or amendments have
been prepared by the Company in conformity with the requirements of the Act, and
the Rules and Regulations and which were declared effective by the Commission on
April 30, 1999. The Company will promptly file a further amendment to said
registration statement in the form heretofore delivered to the Underwriter and
will not file any other amendment thereto to which the Underwriter shall have
objected verbally or in writing after having been furnished with a copy thereof.
Except as the context may otherwise require, such registration statement, as
amended, on file with the Commission at the time the registration statement
becomes effective (including the prospectus, financial statements, any
schedules, exhibits and all other documents filed as a part thereof or that may
be incorporated therein (including, but not limited to those documents or
information incorporated by reference therein) and all information deemed to be
a part thereof as of such time pursuant to paragraph (b) of Rule 430(A) of the
Rules and Regulations), is hereinafter called the "Registration Statement," and
the form of prospectus in the form as filed with the Commission pursuant to Rule
424(b) of the Rules and Regulations, is hereinafter called the "Final
Prospectus."

    (ii) Neither the Commission nor any state regulatory authority has issued
any order preventing or suspending the use of any Prospectus or the Registration
Statement and no proceeding for an order suspending the effectiveness of any
prospectus or the Registration Statement or any of the Company's securities has
been instituted or is pending or threatened. Each such Prospectus and/or any
supplement thereto has conformed in all material respects with the requirements
of the Act and the Rules and Regulations and on its date did not include any
untrue statement of a material fact or omit to state a material fact necessary
to make the statements therein not misleading, in light of the circumstances
under which they were made; and when the Prospectus and any supplements thereto
becomes legally effective and for twenty-five (25) days subsequent thereto (i)
the Prospectus and/or any supplement thereto will contain all statements which
are required to be stated therein by the Act and Rules and Regulations, and (ii)
the Prospectus and/or any supplement thereto will not include 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 therein not misleading, in
light of the circumstances under which they were made; provided, however, that
no representations, warranties or agreements are made hereunder as to
information contained in or omitted from the Prospectus in reliance upon, and in
conformity with, the written information furnished to the Company by you as set
forth in Section 2(e) above.

    (iii)The Company has been duly incorporated and is validly existing as a
corporation in good standing under the laws of the state of its incorporation,
with full power and authority (corporate and other) to own its properties and
conduct its businesses as described in the Prospectus and is duly qualified to
do business as a foreign corporation in good standing in all other jurisdictions
in which the nature of its business or the character or location of its
properties requires such qualification, except where the failure to so qualify
would not have a material adverse effect on the business, properties or
operations of the Company as a whole.

    (iv) The Company has full legal right, power and authority to authorize,
issue, deliver and sell the Securities, the Option Securities and the
Underwriters' Warrants and to enter into this Agreement, the Underwriters'
Warrant dated as of the initial closing date to be executed and delivered by the
Company to the Representative (the "Underwriters' Warrant Agreement"), and the
Financial Advisory and Investment Banking Agreement dated as of the Initial

amendment to or supplement to the Prospectus of which you shall not previously
have been advised and furnished with a copy or to which you or your counsel
shall have reasonably objected or which is not in material compliance with the
Act and the Rules and Regulations or applicable state law.

    As soon as the Company is advised thereof, the Company will advise you, and
confirm the advice in writing, of the receipt of any comments of the Commission
or any state securities department, when the Registration Statement becomes
effective if the provisions of Rule 430A promulgated under the Act will be
relied upon, when the Prospectus has been filed in accordance with said Rule
430A, of the effectiveness of any posteffective amendment to the Registration
Statement or Prospectus, or the filing of any supplement to the Prospectus or
any amended Prospectus, of any request made by the Commission or any state
securities department for amendment of the Prospectus or for supplementing of
the Prospectus or for additional information with respect thereto, of the
issuance of any stop order suspending the effectiveness of the Prospectus or any
order preventing or suspending the use of any Prospectus or any order suspending
trading in the Common Stock of the Company, or of the suspension of the
qualification of the Securities, the Option Securities or the Underwriters'
Warrants for offering in any jurisdiction, or of the institution of any
proceedings for any such purposes, and will use its best efforts to prevent the
issuance of any such order and, if issued, to obtain as soon as possible the
lifting or dismissal thereof.

    The Company has caused to be delivered to you copies of such Prospectus, and
the Company has consented and hereby consents to the use of such copies for the
purposes permitted by law. The Company authorizes you and the dealers to use the

as in the opinion of your counsel and our counsel the use thereof is required to
comply with the applicable provisions of the Act and the Rules and Regulations.
The Company will prepare and file with the states, promptly upon your request,
any such amendments or supplements to the Prospectus, and take any other action,
as, in the opinion of your counsel, may be necessary or advisable in connection
with the initial sale of the Securities, the Option Securities and the
Underwriters' Warrants and will use its best efforts to cause the same to become
effective as promptly as possible.

Agreement, and (ii) the fifth business day after the effective date of the

    In case of the happening, at any time within such period as a Prospectus is
required under the Act to be delivered in connection with the initial sale of
the Securities, the Option Securities and the Underwriters' Warrants of any
event of which the Company has knowledge and which materially affects the
Company, or the securities thereof, and which should be set forth in an
amendment of or a supplement to the Prospectus in order to make the statements
therein not then misleading, in light of the circumstances existing at the time
the Prospectus is required under the Act to be delivered, or in case it shall be
necessary to amend or supplement the Prospectus to comply with the Act, the
Rules and Regulations or any other law, the Company will forthwith prepare and
furnish to you copies of such amended Prospectus or of such supplement to be
attached to the Prospectus, in such quantities as you may reasonably request, in
order that the Prospectus, as so amended or supplemented, will not contain 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 therein not misleading
in light of the circumstances under which they are made. The preparation and
furnishing of any such amendment or supplement to the Prospectus or supplement
to be attached to the Prospectus shall be without expense to you.

    The Company will to the best of its ability comply with the Act, the

    (b) The Company will cooperate to qualify the Securities and the Option
Securities and the Underwriters' Securities for initial sale under the

authorized and reserved for issuance and when issued and delivered in accordance
with the respective terms of the Warrant Agreement and the Underwriter's
Warrant, respectively, will be duly and validly issued, fully paid and
nonassessable.

    (G) To the knowledge of such counsel, there are no claims, suits or other
legal proceedings pending or threatened against the Company in any court or

the Company or the financial condition of the Company as a whole, except as set

agency or instrumentality having jurisdiction over the Company, or its
properties (other than registration under the Act or qualification under state
or foreign securities law or approval by the NASD) is required for the valid

Securities or the Underwriters' Warrant.

    (L) The statements in the Prospectus under "Risk Factors-Control by Existing
Stockholders," "Risk of Third-Party Claims of Infringement", "Patents and
Proprietary Technology", "Management-Limitation of Liability" "Description of
the Securities," and "Shares Eligible For Future Sale" have been reviewed by
such counsel, and insofar as they refer to statements of law, descriptions of
statutes, licenses, rules or regulations or legal conclusions, are correct in
all material respects.

    In addition, such counsel shall state that such counsel has participated in
conferences with officials and other representatives of the Company,
Underwriters' Counsel and the independent certified public accountants of the
Company, at which such conferences the contents of the Registration Statement
and Prospectus and related matters were discussed, and although they have not
certified the accuracy or completeness of the statements contained in the
Registration Statement or the Prospectus, nothing has come to the attention of
such counsel which leads them to believe that, at the time the Registration
Statement became effective and at all times subsequent thereto up to and on the
Closing Date and on any later date on which Option Shares are to be purchased,
the Registration Statement and any amendment or supplement, when such documents
became effective or were filed with the Commission (other than the financial
statements including the notes thereto and supporting schedules and other
financial and statistical information derived therefrom, as to which such
counsel need express no comment) contained any untrue statement of a material
fact or omitted to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, or at the Closing Date
or any later date on which the Option Shares are to be purchased, as the case
may be, the Prospectus and any amendment or supplement thereto (other than the
financial statements including the notes thereto and other financial and
statistical information derived therefrom, as to which such counsel need express
no comment) contained any untrue statement of a material fact or omitted to
state a material fact necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading.

    Such opinion shall also cover such other matters incident to the
transactions contemplated hereby and the offering Prospectus as you or counsel
to the Underwriter shall reasonably request. In rendering such opinion, to the
extent deemed reasonable by them, such counsel may rely upon certificates of any
officer of the Company or public officials as to matters of fact of which the
maker of such certificate has knowledge.

    (ii) a certificate, signed by the Chief Executive Officer and the Principal
Financial or Accounting Officer of the Company dated the Closing Date, to the
effect that with regard to the Company, each of the conditions set forth in
Section 5(d) have been satisfied.

    (iii) a letter, addressed to the Underwriter and in form and substance
satisfactory to the Underwriter in all respects (including the nature of the
changes or decreases, if any, referred to in clause (D) below), from Ernst &
Young LLP, dated, respectively, as of the effective date of the Registration
Statement and as of the Closing Date, as the case may be:

    (A) Confirming that they are independent public accountants with respect to
the Company and its consolidated subsidiaries, if any, within the meaning of the
Act and the applicable published Rules and Regulations.

    (B) Stating that, in their opinion, the financial statements, related notes
and schedules of the Company and its consolidated subsidiaries, if any, included

respects with the applicable accounting requirements of the Act and the
published Rules and Regulations thereunder.

    (C) Stating that, with respect to the period from June 30, 1998 to a
specified date ("specified date") not earlier than five (5) business days prior
to the date of such letter, they have read the minutes of meetings of the
stockholders

                                       15
<PAGE>   16
and board of directors (and various committees thereof) of the Company and its
consolidated subsidiaries, if any, for the period from June 30, 1998 through the
specified date, and made inquiries of officers of the Company and its
consolidated subsidiaries, if any, responsible for financial and accounting
matters and, especially as to whether there was any decrease in sales, income
before extraordinary items or net income as compared with the corresponding
period in the preceding year; or any change in the capital stock of the Company
or any change in the long term debt or any increase in the short-term bank
borrowings or any decrease in net current assets or net assets of the Company or
of any of its consolidated subsidiaries, if any, and further stating that while
such procedures and inquiries do not constitute an examination made in
accordance with generally accepted auditing standards, nothing came to their
attention which caused them to believe that during the period from June 30,
1998, through the specified date there were any decreases as compared with the
corresponding period in the preceding year in sales, income before extraordinary
items or net income; or any change in the capital stock of the Company or
consolidated subsidiary, if any, or any change in the long term debt or any
increase in the short-term bank borrowings (other than any increase in
short-term bank borrowings in the ordinary course of business) of the Company or
any consolidated subsidiary, if any, or any decrease in the net current assets
or net assets of the Company or any consolidated subsidiary, if any; and

    (D) Stating that they have carried out certain specified procedures
(specifically set forth in such letter or letters) as specified by the
Underwriter (after consultations with Ernst & Young, LLP relating to such
procedures), not constituting an audit, with respect to certain tables,
statistics and other financial data in the Prospectus specified by the
Underwriter and such financial data not included in the Prospectus but from
which information in the Prospectus is derived, and which have been obtained
from the general accounting records of the Company or consolidated subsidiaries,
if any, or from such accounting records by analysis or computation, and having
compared such financial data with the accounting records of the Company or the
consolidated subsidiaries, if any, stating that they have found such financial
data to agree with the accounting records of the Company.

    (c) All corporate proceedings and other legal matters relating to this
Agreement, the Prospectus and other related matters shall be satisfactory to or
approved by counsel to the Underwriters and you shall have received from Foley,
Hoag & Eliot, LLP a signed opinion dated as of each closing date, with respect
to the incorporation of the Company, the validity of the Securities, the form of
the Prospectus, (other than the financial statements together with related notes

therefrom, as to which such counsel need express no opinion), the execution of
this Agreement and other related matters as you may reasonably require.

Company contained in this Agreement shall be true and correct in all material
respects with the same effect as if made on and as of such closing date; (ii)
the Prospectus and any amendments or supplements thereto shall contain all
statements which are required to be stated therein in accordance with the Act
and the Rules and Regulations and in all material respects conform to the
requirements thereof, and neither the Prospectus nor any amendment or supplement
thereto shall contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary, in light of the
circumstances under which they were made, in order to make the statements
therein not misleading; (iii) there shall have been since the respective dates

the Prospectus, no action, suit or proceeding at law or in equity shall be
pending or threatened against the Company which would be required to be set
forth in the Prospectus, and no proceedings shall be pending or threatened
against the Company or any subsidiary before or by any commission, board or

property, condition (financial or otherwise), results of operations or general
affairs of the Company.

       (e) On the Initial Closing Date, the Company shall have executed and
delivered to the Underwriter, (i) the Underwriters' Warrant substantially in the
form filed as an Exhibit to the Registration Statement in final form and

liabilities, joint or several (which shall, for all purposes of this Agreement,
include, but not be limited to, all costs of defense and investigation and all
attorneys' fees) to which the Company or any such director, officer or
controlling person may become subject under the Act or otherwise, insofar as
such losses, claims, damages or liabilities (or

                                       17
<PAGE>   18
actions in respect thereof) arise out of or are based upon any untrue statement
or alleged untrue statement of any material fact contained in the Prospectus, or
any amendment or supplement thereto, or arise out of or are based upon the
omission or the alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, in
each case to the extent, but only to the extent, that such untrue statement or
alleged untrue statement or omission was made in the Prospectus, or such
amendment or supplement, in reliance upon and in conformity with written
information furnished to the Company by you specifically for use in the
preparation thereof and from and against any and all losses caused by an untrue
statement or alleged untrue statement of a material fact contained in the
Prospectus (if used within the Applicable Period and as amended or supplemented
if the Company shall have furnished any amendments or supplements thereto), or
caused by any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, if the person asserting such losses purchased Securities from such
Underwriter and a copy of the Final Prospectus ( as then amended or supplemented
if the Company shall have furnished any amendments or supplements thereto) was
not sent or given by or on behalf of such Underwriter to such person, if
required by law so to have been delivered, at or prior to the written
confirmation of the sale of the Securities to such person, and if the Prospectus
( as so amended or supplemented ) would have cured the defect giving rise to
such loss, claim, damage or liability. This indemnity will be in addition to any
liability which any Underwriter may otherwise have.

       (c) Promptly after receipt by an indemnified party under this Section of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section, notify the indemnifying party of the commencement thereof, but the
omission so to notify the indemnifying party will not relieve it from any
liability which it may have to any indemnified party otherwise than under this
Section. In case any such action is brought against any indemnified party, and
it notifies the indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate in, and, to the extent that it may wish,
jointly with any other indemnifying party, similarly notified, to assume the
defense thereof, subject to the provisions herein stated, with counsel
satisfactory to such indemnified party, and after notice from the indemnifying
party to such indemnified party of its election so to assume the defense
thereof, the indemnifying party will not be liable to such indemnified party
under this Section for any legal or other expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation. The indemnified party shall have the right to employ
separate counsel in any such action and to participate in the defense thereof,
but the fees and expenses of such counsel shall not be at the expense of the
indemnifying party if the indemnifying party has assumed the defense of the
action with counsel reasonably satisfactory to the indemnified party; provided
that, if the indemnified party is you or a person who controls you, the fees and
expenses of such counsel shall be at the expense of the indemnifying party if
(i) the employment of such counsel has been specifically authorized in writing
by the indemnifying party or (ii) the named parties to any such action
(including any impleaded parties) include both you or such controlling person
and the indemnifying party and you or such controlling person shall have been
advised by such counsel that there is a conflict of interest which would prevent
counsel for the indemnifying party from representing the indemnifying party and
you or such controlling person (in which case the indemnifying party shall not
have the right to assume the defense of such action on behalf of you or such
controlling person, it being understood, however, that the indemnifying party
shall not, in connection with any one such action or separate but substantially
similar or related actions in the same jurisdiction or which are consolidated
into the same jurisdiction arising out of the same general allegations or
circumstances, be liable for the reasonable fees and expenses of more than one
separate firm of attorneys for you and all such controlling persons, which firm
shall be designated in writing by you). No settlement of any action against an
indemnified party shall be made without the consent of the indemnified party,
which shall not be unreasonably withheld in light of all factors of importance
to such indemnified party.

    8. Contribution. In order to provide for just and equitable contribution
under the Act in any case in which (i) the indemnifying party makes a claim for
indemnification pursuant to Section 7 hereof but it is judicially determined (by
the entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that the express provisions of Section 7 provide for indemnification in such
case, or (ii) contribution under the Act may be required on the part of the
Underwriters, then the Company and the Underwriters in the aggregate shall
contribute to the aggregate losses, claims, damages, or liabilities to which
they may be subject (which shall, for all purposes of this Agreement, include,
but not be limited to, all costs of defense and investigation and all attorneys'

                                       18
<PAGE>   19
fees) in either such case (after contribution from others) in such proportions
that the Underwriters are responsible in the aggregate for that portion of such
losses, claims, damages or liabilities determined by multiplying the total
amount of such losses, claims, damages or liabilities times the difference
between the public offering price and the commission to the Underwriter and
dividing the product thereof by the public offering price, and the Company, if
applicable, shall be responsible for that portion of such losses, claims,
damages or liabilities times the commission to the Underwriters and dividing the
product thereof by the public offering price; provided, however, that the
Underwriters shall not be required to so contribute any amount in excess of the
underwriting discount applicable to the Securities purchased by the Underwriters
hereunder if such allocation is not permitted by applicable law, then the
relative fault of the Company and the Underwriters in connection with the
statements or omissions which resulted in such damages and other relevant
equitable considerations shall also be considered. No person guilty of a
fraudulent misrepresentation (within the meaning of Section 12(2) of the Act)
shall be entitled to contribution from any person who is not guilty of such
fraudulent misrepresentation. The foregoing contribution agreement shall in no
way affect the contribution liabilities of any person having liability under
Section 12 of the Act other than the Company and the Underwriter. As used in
this paragraph, the term "Underwriters" includes any person who controls the
Underwriters within the meaning of Section 15 of the Act. If the full amount of
the contribution specified in this paragraph is not permitted by law, then any
Underwriter and each person who controls any Underwriter shall be entitled to
contribution from the Company, to the full extent permitted by law.


    9. Effective Date. This Agreement shall become effective at 10:00 a.m. New
York time on the next full business day following the effective date of the
Registration Statement, or at such other time after the effective date of the
Prospectus as you in your discretion shall first commence the public offering of
any of the Securities covered thereby, provided, however, that at all times the
provisions of Sections 7, 8, 9 and 11 shall be effective.

     10.  Termination.

     (a)  This Agreement, may be terminated at any time prior to the Closing
          Date by you if in your judgment it is impracticable to offer for sale
          or to enforce contracts made by you for the sale of the Securities
          agreed to be sold hereunder by reason of (i) the Company as a whole
          having sustained a material loss, whether or not insured, by reason of
          fire, earthquake, flood, accident or other calamity, or from any labor
          dispute or court or government action, order or decree, (ii) trading
          in securities of the Company having been suspended by a state
          securities administrator or by the Commission, (iii) material
          governmental restrictions having been imposed on trading in securities
          generally (not in force and effect on the date hereof) or trading on
          the New York Stock Exchange, American Stock Exchange, or in the
          over-the-counter market shall have been suspended, (iv) a banking
          moratorium having been declared by federal or New York State
          authorities, (v) an outbreak or escalation of hostilities or other
          national or international calamity having occurred, (vi) the passage
          by the Congress of the United States or by any state legislative body,
          of any act or measure, or the adoption of any orders, rules or
          regulations by any governmental body or any authoritative accounting
          institute or board, or any governmental executive, which is believed
          likely by you to have a material impact on the business, financial
          condition or financial statements of the Company; or (vii) any
          material adverse change having occurred, since the respective dates as
          of which information is given in the Prospectus, in the condition,
          financial or otherwise, of the Company as a whole, whether or not
          arising in the ordinary course of business, (viii) Anthony J. Armini
          ceases to be employed by the Company in his present capacity; (ix) the
          Securities are not listed on any exchange or on Nasdaq Small Cap.

          (b) If you elect to prevent this Agreement from becoming effective or
to terminate this Agreement as provided in this Section 10 or in Section 9, the
Company shall be promptly notified by you, by telephone or telegram, confirmed
by letter.

                           SELECTED DEALERS AGREEMENT




                                    , 1999


Dear Sirs:



    1. Westport Resources Investment Services, Inc. named as the Underwriter
("Underwriter") in the enclosed preliminary Prospectus, proposes to offer on a
firm commitment basis, subject to the terms and conditions and execution of the
Underwriting Agreement, 1,000,000 Shares of Common Stock at $7.50 per share and
1,000,000 Redeemable Warrants at $0.10 per Warrant ("Securities") of the above
Company. The Securities are more particularly described in the enclosed
preliminary Prospectus, additional copies of which will be supplied in
reasonable quantities upon request. Copies of the definitive Prospectus will be
supplied after the effective date of the Registration Statement.



    2. The Underwriter is soliciting offers to buy, upon the terms and
conditions hereof, a part of the Securities from Selected Dealers, including you
who are to act as principal and who are (i) registered with the Securities and
Exchange Commission ("Commission") as broker-dealers under the Securities
Exchange Act of 1934, as amended ("1934 Act"), and members in good standing with
the National Association of Securities Dealers, Inc. ("NASD"), or (ii) dealers
or institutions with their principal place of business located outside the
United States, its territories and possessions who are not eligible for
membership in the NASD and who agree to make no sales within the United States,
its territories or possessions or to persons who are nationals thereof or
residents therein and, in making sales, to comply with the NASD's Interpretation
with Respect to FreeRiding and Withholding and with Sections 2730, 2740 and
2420, to the extent applicable to foreign nonmember brokers or dealers, and
Section 2750 of the NASD's Rules of Fair Practice. The Securities are to be
offered at a public price of $7.50 per share of Common Stock and $0.10 per
Redeemable Warrant. Selected Dealers will be allowed a concession of not less
than $    per share and $.005 per Redeemable Warrant, except as provided below.
You will be notified of the precise amount of such concession prior to the
effective date of the Registration Statement. This offer is solicited subject to
the issuance and delivery of the Securities and their acceptance by the
Underwriter, to the approval of legal matters by counsel and to the terms and
conditions as herein set forth.


    3. Your offer to purchase may be revoked in whole or in part without
obligation or commitment of any kind by you and any time prior to acceptance and
no offer may be accepted by us and no sale can be made until after the
registration statement covering the Securities has become effective with the
Commission. Subject to the foregoing, upon execution by you of the Offer to
Purchase below and the return of same to us, you shall be deemed to have offered
to purchase the number of Securities set forth in your offer on the basis set
forth in paragraph 2 above. Any
<PAGE>   2
oral notice by us of acceptance of your offer shall be immediately followed by
written or telegraphic confirmation preceded or accompanied by a copy of the
Prospectus. If a contractual commitment arises hereunder, all the terms of this
Selected Dealers Agreement shall be applicable. We may also make available to
you an allotment to purchase Securities, but such allotment shall be subject to
modification or termination upon notice from us any time prior to an exchange of
confirmations reflecting completed transactions. All references hereafter in
this Agreement to the purchase and sale of Securities assume and are applicable
only if contractual commitments to purchase are completed in accordance with the
foregoing.

    4. You agree that in reoffering said Securities, if your offer is accepted
after the effective date, you will make a bona fide public distribution of same.
You will advise us upon request of Securities purchased by you remaining unsold
and we shall have the right to repurchase such Securities upon demand at the
public offering price without paying the concession with respect to any
Securities so repurchased. Any of the Securities purchased by you pursuant to
this Agreement are to be subject to the terms hereof. Securities shall not be
offered or sold by you below the public offering price before the termination of
this Agreement.

    5. Payment for Securities which you purchase hereunder shall be made by you
on or before five (5) business days after the date of each confirmation by
certified or bank cashier's check payable to the Underwriter. Certificates for
the Securities shall be delivered as soon as practicable after delivery
instructions are received by the Underwriter.

    6. A registration statement covering the offering has been filed with the
Securities and Exchange Commission in respect to the Securities. You will be
promptly advised when the registration statement becomes effective. Each
Selected Dealer in selling Securities pursuant hereto agrees (which agreement
shall also be for the benefit of the Company) that it will comply with the
applicable requirements of the Securities Act of 1933 and of the Securities
Exchange Act of 1934 and any applicable rules and regulations issued under said
Acts. No person is authorized by the Company or by the Underwriter to give any
information or to make any representations other than those contained in the
Prospectus in connection with the sale of the Securities. Nothing contained
herein shall render the Selected Dealers a member of the Underwriting Group or
partners with the Underwriter or with one another.

    7. You will be informed by us as to the states in which we have been advised
by counsel the Securities have been qualified for sale or are exempt under the
respective securities or blue sky laws of such states, but we have not assumed
and will not assume any obligation or responsibility as to the right of any
Selected Dealer to sell Securities in any state. You agree not to sell
Securities in any other state or jurisdiction and to not sell Securities in any
state or jurisdiction unless you are qualified or licensed to sell securities in
such state or jurisdiction.

    8. The Underwriter shall have full authority to take such action as it may
deem advisable in respect of all matters pertaining to the offering or arising
thereunder. The Underwriter shall not be under any liability to you, except such
as may be incurred under the Securities Act of 1933 and the rules and
regulations thereunder, except for lack of good faith and except for obligations
assumed by us in this Agreement, and no obligation on our part shall be implied
or inferred herefrom.

    9. Selected Dealers will be governed by the conditions herein set forth
until this Agreement is terminated. This Agreement will terminate when the
offering is completed. Nothing herein contained shall be deemed a commitment on
our part to sell you any Securities; such contractual commitment can only be
made in accordance with the provisions of paragraph 3 hereof.

    10. You represent that you are a member in good standing of the NASD and
registered as a broker-dealer with the Commission, or that you are a foreign
broker-dealer not eligible for membership under Section 1 of the Bylaws of the
NASD who agrees to make no sales within the United States, its territories or
possessions or to persons who are nationals thereof or residents therein and, in
making sales, to comply with the NASD's interpretation with Respect to
FreeRiding and Withholding and with Sections 2730, 2740 and 2420 to the extent
applicable to foreign nonmember brokers and dealers, and Section 2750 of the
NASD's Rules of Fair Practice. Your attention is called to and you agree to
comply with the following: (a) Article III, Section 1 of the Rules of Fair
Practice of the NASD and the interpretations of said Section promulgated by the
Board of Governors of the NASD including Section 2740 and the


                                       2
<PAGE>   3
interpretation with respect to "Free-Riding and Withholding;" (b) Section 10(b)
of the 1934 Act, Rule 10b-10 and Regulation M of the general rules and
regulations promulgated under the 1934 Act; and (c) Rule 15c2-8 of the general
rules and regulations promulgated under the 1934 Act requiring the distribution
of a preliminary Prospectus to all persons reasonably expected to be purchasers
of the Securities from you at least 48 hours prior to the time you expect to
mail confirmations. You, as a member of the NASD, by signing this Agreement,
acknowledge that you are familiar with the cited laws and rules and agree that
you will not directly and/or indirectly violate any provisions of applicable law
in connection with your participation in the distribution of the Securities.

    11. In addition to compliance with the provisions of paragraph 10 hereof,
you will not, until advised by us in writing or by wire that the entire offering
has been distributed and closed, bid for or purchase Securities in the open
market or otherwise make a market in the Securities or otherwise attempt to
induce others to purchase the Securities in the open market. Nothing contained
in this paragraph 11 shall, however, preclude you from acting as agent in the
execution of unsolicited orders of customers in transactions effectuated for
them through a market maker.

    12. You understand that the Underwriter may in connection with the offering
engage in stabilizing transactions. If the Underwriter contracts for or
purchases in the open market in connection with such stabilization any
Securities sold to you hereunder and not effectively placed by you, the
Underwriter may charge you the Selected Dealer's concession originally allowed
you on the Securities so purchased and you agree to pay such amount to us on
demand.

    13. By submitting an Offer to Purchase you confirm that you may, in
accordance with Rule 15c-1 adopted under the 1934 Act, agree to purchase the
number of Securities you may become obligated to purchase under the provisions
of this Agreement.

     14. All communications from you should be directed to us at Westport
Resources Investment Services, Inc., 315 Post Road West, Westport, CT 06880.
Attn: John D. Lane (1-800-935-0222) and fax (203-291-7931). All communications
from us to you shall be directed to the address to which this letter is mailed.

Very truly yours,

this Warrant and the price to be paid for the Securities may be adjusted from
time to time as hereinafter set forth. The purchase price of a Security in
effect at any time and as adjusted from time to time is hereinafter sometimes
referred to as the "Exercise Price." This Warrant is or may be one of a series
of Warrants identical in form issued by the Company to purchase an aggregate of
100,000 Shares of Common Stock and 100,000 Redeemable Warrants. The Securities,
as adjusted from time to time, underlying the Warrants are hereinafter sometimes
referred to as "Warrant Securities". The Securities issuable upon the exercise
hereof are in all respects identical to the securities being purchased by the
Underwriter for resale to the public pursuant to the terms and conditions of the
Underwriting Agreement entered into on this date between the Company and Holder.



     (a) Exercise of Warrant. Subject to the provisions of Section (g) hereof,
this Warrant may be exercised in whole or in part at anytime or from time to
time on or after       , 1999, but not later than 3:30 p.m., Eastern Time on
         , 2004, or if       , 2004 is a day on which banking institutions are
authorized by law to close, then on the next succeeding day which shall not be
such a day, by presentation and surrender hereof to the Company or at the office
of its stock transfer agent, if any, with the Purchase Form annexed hereto duly
executed and accompanied by payment of the Exercise Price for the number of
shares of Common Stock or Redeemable Warrants, as the case may be as specified
in such Form, together with all federal and state taxes applicable upon such
exercise. The Company agrees to provide notice to the Holder that any tender
offer is being made for the Securities no later than the first business day
after the day the Company becomes aware that any tender offer is being made for
the Securities. If this Warrant should be exercised in part only, the Company
shall, upon surrender of this Warrant for cancellation, execute and deliver a
new Warrant evidencing the right of the Holder to purchase the balance of the
shares purchasable hereunder along with any additional Redeemable Warrants not
exercised. Upon receipt by the Company of this Warrant at the office of the


<PAGE>   2
Company or at the office of the Company's stock transfer agent, in proper form
for exercise and accompanied by the total Exercise Price, the Holder shall be
deemed to be the holder of record of the Securities issuable upon such exercise,
notwithstanding that the stock transfer books of the Company shall then be
closed or that certificates representing such Securities shall not then be
actually delivered to the Holder.


    (b) Reservation of Securities. The Company hereby agrees that at all times
there shall be reserved for issuance and/or delivery upon exercise of this
Warrant such number of shares of Securities as shall be required for issuance or
delivery upon exercise of this Warrant. The Company covenants and agrees that,
upon exercise of the Warrants and payment of the Exercise Price therefor, all
Securities and other securities issuable upon such exercise shall be duly and
validly issued, fully paid, non-assessable and not subject to the preemptive
rights of any stockholder. As long as the Warrants shall be outstanding, the
Company shall use its best efforts to cause all Securities issuable upon the
exercise of the Warrants to be listed (subject to official notice of issuance)
on all securities exchanges on which the Common Stock issued to the public in
connection herewith may then be listed and/or quoted on NASDAQ.

    (c) Fractional Shares. No fractional shares or scrip representing fractional
shares shall be issued upon the exercise of this Warrant. With respect to any
fraction of a share called for upon any exercise hereof, the Company shall pay
to the Holder an amount in cash equal to such fraction multiplied by the current
market value of such fractional share, determined as follows:

       (1) If the Securities are listed on a national securities exchange or
admitted to unlisted trading privileges on such exchange, the current value
shall be the last reported sale price of the Common Stock on such exchange on
the last business day prior to the date of exercise of this Warrant or if no
such sale is made on such day, the average of the closing bid and asked prices
for such day on such exchange; or

       (2) If the Securities are not so listed or admitted to unlisted trading
privileges, the current value shall be the mean of the last reported bid and
asked prices reported by the National Association of Securities Dealers
Automated Quotation System (or, if not so quoted on NASDAQ or quoted by the
National Quotation Bureau, Inc.) on the last business day prior to the date of
the exercise of this Warrant; or

       (3) If the Securities are not so listed or admitted to unlisted trading
privileges and bid and asked prices are not so reported, the current value shall
be an amount, not less than book value, determined in such reasonable manner as
may be prescribed by the Board of Directors of the Company, such determination
to be final and binding on the Holder.

    (d) Exchange, Assignment or Loss of Warrant. This Warrant is exchangeable,
without expense, at the option of the Holder, upon presentation and surrender
hereof to the Company or at the office of its stock transfer agent, if any, for
other Warrants of different denominations entitling the Holder thereof to
purchase (under the same terms and conditions as provided by this Warrant) in
the aggregate the same number of Securities purchasable hereunder. This Warrant
may not be sold, transferred, assigned, or hypothecated until after one year
from the effective date of the registration statement except that it may be (i)
assigned in whole or in part to the officers of the "Underwriter(s)", and
(ii)transferred to any successor to the business of the "Underwriter(s)." Any
such assignment shall be made by surrender of this Warrant to the Company, or at
the office of its stock transfer agent, if any, with the Assignment Form annexed
hereto duly executed and with funds sufficient to pay any transfer tax;
whereupon the Company shall, without charge, execute and deliver a new Warrant
in the name of the assignee named in-such instrument of assignment, and this
Warrant shall promptly be canceled. This Warrant may be divided or combined with
other Warrants which carry the same rights upon presentation hereof at the
office of the Company or at the office of its stock transfer agent, if any,
together with a written notice specifying the names and denominations in which
new Warrants are to be issued and signed by the Holder hereof. The term
"Warrant" as used herein includes any Warrants issued in substitution for or
replacement of this Warrant, or into which this Warrant may be divided or
exchanged. Upon receipt by the Company of evidence satisfactory to it of the
loss, theft, destruction or mutilation of this Warrant, and (in the case of
loss, theft or destruction) of reasonably satisfactory indemnification, and upon
surrender and cancellation of this Warrant, if mutilated, the Company will
execute and deliver a new Warrant of like tenor and date.


                                       2
<PAGE>   3
Any such new Warrant executed and delivered shall constitute an additional
contractual obligation on the part of the Company, whether or not the Warrant so
lost, stolen, destroyed, or mutilated shall be at any time enforceable by
anyone.

    (e) Rights of the Holder. The Holder shall not, by virtue hereof, be
entitled to any rights of a stockholder in the Company, either at law or equity,
and the rights of the Holder are limited to those expressed in the Warrant and
are not enforceable against the Company except to the extent set forth herein.

    (f) Notices to Warrant Holders. So long as this Warrant shall be outstanding
and unexercised (i) if the Company shall pay any dividend exclusive of a cash
dividend, or make any distribution upon the Common Stock, or (ii) if the Company
shall offer to the holders of Common Stock for subscription or purchase by them
any shares of stock of any class or any other rights, or (iii) if any capital
reorganization of the Company, reclassification of the capital stock of the
Company, consolidation or merger of the Company with or into another
corporation, sale, lease or transfer of all or substantially all of the property
and assets of the Company to another corporation, or voluntary or involuntary
dissolution, liquidation or winding up of the Company shall be effected, then,
in any such case, the Company shall cause to be delivered to the Holder, at
least ten (10) days prior to the date specified in (x) or (y) below, as the case
may be, a notice containing a brief description of the proposed action and
stating the date on which (x) a record is to be taken for the purpose of such
dividend, distribution or rights, or (y) such reclassification, reorganization,
consolidation, merger, conveyance, lease, dissolution, liquidation or winding up
is to take place and the date, if any, is to be fixed, as of which the holders
of Common Stock of record shall be entitled to exchange their shares of Common
Stock for equivalent securities or other property deliverable upon such
reclassification, reorganization, consolidation, merger, conveyance,
dissolution, liquidation or winding up.

    (g) Adjustment of Exercise Price and Number of Shares of Common Stock
Deliverable.

    (A)(i) Except as hereinafter provided, in the event the Company shall, at
any time or from time to time after the date hereof, issue any shares of Common
Stock as a stock dividend to the holders of Common Stock, or subdivide or
combine the outstanding shares of Common Stock into a greater or lesser number
of shares (any such issuance, subdivision or combination being herein call a
"Change of Shares"), then, and thereafter upon each further Change of Shares,
the Exercise Price of the Common Stock issuable upon the exercise of the Warrant
and the Redeemable Warrant in effect immediately prior to such Change of Shares
shall be changed to a price (including any applicable fraction of a cent to the
nearest cent) determined by dividing (i) the sum of (a) the total number of
shares of Common Stock outstanding immediately prior to such Change of Shares,
multiplied by the Exercise Price in effect immediately prior to such Change of
Shares, and (b) the consideration, if any, received by the Company upon such
issuance, subdivision or combination by (ii) the total number of shares of
Common Stock outstanding immediately after such Change of Shares; provided,
however, that in no event shall the Exercise Price be adjusted pursuant to this
computation to an amount in excess of the Exercise Price in effect immediately
prior to such computation, except in the case of a combination of outstanding
shares of Common Stock.

    For the purposes of any adjustment to be made in accordance with this
Section (g) the following provisions shall be applicable:

    (I) Shares of Common Stock issuable by way of dividend or other distribution
on any capital stock of the Company shall be deemed to have been issued
immediately after the opening of business on the day following the record date
for the determination of shareholders entitled to receive such dividend or other
distribution and shall be deemed to have been issued without consideration.

    (II) The number of shares of Common Stock at any one time outstanding shall
not be deemed to include the number of shares issuable (subject to readjustment
upon the actual issuance thereof) upon the exercise of options, rights or
warrants and upon the conversion or exchange of convertible or exchangeable
securities.

    (ii) Upon each adjustment of the Exercise Price pursuant to this Section
(g), the number of shares of Common Stock and Redeemable Warrants purchasable
upon the exercise of each Warrant shall be the number derived by multiplying the
number of shares of Common Stock and Redeemable Warrants purchasable immediately
prior to


                                       3
<PAGE>   4
such adjustment by the Exercise Price in effect prior to such adjustment and
dividing the product so obtained by the applicable adjusted Exercise Price.



    (B) In case of any reclassification or change of outstanding Securities
issuable upon exercise of the Warrants (other than a change in par value, or
from par value to no par value, or from no par value to par value or as a result
of a subdivision or combination), or in case of any consolidation or merger of
the Company with or into another corporation other than a merger with a
"Subsidiary" (which shall mean any corporation or corporations, as the case may
be, of which capital stock having ordinary power to elect a majority of the
Board of Directors of such corporation (regardless of whether or not at the time
capital stock of any other class or classes of such corporation shall have or
may have voting power by reason of the happening of any contingency) is at the
time directly or indirectly owned by the Company or by one or more Subsidiaries)
or by the Company and one or more Subsidiaries in which merger the Company is
the continuing corporation and which does not result in any reclassification or
change of the then outstanding shares of Common Stock or other capital stock
issuable upon exercise of the Warrants (other than a change in par value, or
from par value to no par value, or from no par value to par value or as a result
of subdivision or combination) or in case of any sale or conveyance to another
corporation of the property of the Company as an entirety or substantially as an
entirety, then, as a condition of such reclassification, change, consolidation,
merger, sale or conveyance, the Company, or such successor or purchasing
corporation, as the case may be, shall make lawful and adequate provision
whereby the Holder of each Warrant then outstanding shall have the right
thereafter to receive on exercise of such Warrant the kind and amount of
securities and property receivable upon such reclassification, change,
consolidation, merger, sale or conveyance by a holder of the number of
securities issuable upon exercise of such Warrant immediately prior to such
reclassification, change, consolidation, merger, sale or conveyance and shall
forthwith file at the principal office of the Company a statement signed on its
behalf by its President or a Vice President and by its Treasurer or an Assistant
Treasurer or its Secretary or an Assistant Secretary evidencing such provision.
Such provisions shall include provision for adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in Section
(g)(A). The above provisions of this Section (g)(B) shall similarly apply to
successive reclassifications and changes of shares of Common Stock and to
successive consolidations, mergers, sales or conveyances.

    (C) Irrespective of any adjustments or changes in the Exercise Price or the
number of Securities purchasable upon exercise of the Warrants, the Warrant
Certificates theretofore and thereafter issued shall, unless the Company shall
exercise its option to issue new Warrant Certificates pursuant hereto, continue
to express the Exercise Price per share and the number of shares purchasable
thereunder as the Exercise Price per share and the number of shares purchasable
thereunder as expressed in the Warrant Certificates when the same were
originally issued.

    (D) After each adjustment of the Exercise Price pursuant to this Section
(g), the Company will promptly prepare a certificate signed on its behalf by the
President or Vice President, and by the Treasurer or an Assistant Treasurer or
the Secretary or an Assistant Secretary, of the Company setting forth: (i) the
Exercise Price as so adjusted, (ii) the number of Securities purchasable upon
exercise of each Warrant, after such adjustment, and (iii) a brief statement of
the facts accounting for such adjustment. The Company will promptly file such
certificate in the Company's minute books and cause a brief summary thereof to
be sent by ordinary first class mail to each Holder at his last address as it
shall appear on the registry books of the Company. No failure to mail such
notice nor any defect therein or in the mailing thereof shall affect the
validity thereof except as to the holder to whom the Company failed to mail such
notice, or except as to the holder whose notice was defective. The affidavit of
an officer or the Secretary or an Assistant Secretary of the Company that such
notice has been mailed shall, in the absence of fraud, be prima facie evidence
of the facts stated therein.

    (E) No adjustment of the Exercise Price shall be made as a result of or in
connection with the issuance or sale of Securities if the amount of said
adjustment shall be less than $.10, provided, however, that in such case, any
adjustment that would otherwise be required then to be made shall be carried
forward and shall be made at the time of and together with the next subsequent
adjustment that shall amount, together with any adjustment so carried forward,
to at least $.10. In addition, Holders shall not be entitled to cash dividends
paid by the Company prior to the exercise of any Warrant or Warrants held by
them.


                                       4
<PAGE>   5
    (F) In the event that the Company shall at any time prior to the exercise of
all Warrants declare a dividend consisting solely of shares of Common Stock or
otherwise distribute to its stockholders any assets, property, rights, or
evidences of indebtedness, the Holders of the unexercised Warrants shall
thereafter be entitled, in addition to the Securities or other securities and
property receivable upon the exercise thereof, to receive, upon the exercise of
such Warrants, the same property, assets, rights, or evidences of indebtedness,
that they would have been entitled to receive at the time of such dividend or
distribution as if the Warrants had been exercised immediately prior to such
dividend or distribution. At the time of any such dividend or distribution, the
Company shall make appropriate reserves to ensure the timely performance of the
provisions of this Section (g).

    (h) Piggyback Registration. If, at any time commencing one year from the
effective date of the registration statement and expiring four (4) years
thereafter, the Company proposes to register any of its securities under the
Securities Act of 1933, as amended (the "Act") (other than in connection with a
merger or pursuant to Form S-8, S-4 or other comparable registration statement)
it will give written notice by registered mail, at least thirty (30) days prior
to the filing of each such registration statement, to the Holders and to all
other Holders of the Warrants and/or the Warrant Securities of its intention to
do so. If the Holder or other Holders of the Warrants and/or Warrant Securities
notify the Company within twenty (20) days after receipt of any such notice of
its or their desire to include any such securities in such proposed registration
statement, the Company shall afford each of the Underwriter and such Holders of
the Warrants and/or Warrant Securities the opportunity to have any such Warrant
Securities registered under such registration statement. In the event any
underwriter underwriting the sale of securities registered by such registration
statement shall limit the number of securities includable in such registration
by shareholders of the Company, the number of such securities shall be allocated
pro rata among the holders of Warrants and the holders of other securities
entitled to piggyback registration rights.

    Notwithstanding the provisions of this Section, the Company shall have the
right at any time after it shall have given written notice pursuant to this
Section (irrespective of whether a written request for inclusion of any such
securities shall have been made) to elect not to file any such proposed
registration statement, or to withdraw the same after the filing but prior to
the effective date thereof.

    (i)    Demand Registration.

    (1) At any time commencing one year from the effective date of the
registration statement and expiring four (4) years thereafter, the Holders of
the Warrants and/or Warrant Securities representing a "Majority" (as hereinafter
defined) of such securities (assuming the exercise of all of the Warrants) shall
have the right (which right is in addition to the registration rights under
Section (i) hereof), exercisable by written notice to the Company, to have the
Company prepare and file with the Securities and Exchange Commission (the
"Commission"), on one occasion, a registration statement and such other
documents, including a prospectus, as may be necessary in the opinion of both
counsel for the Company and counsel for the Underwriter and Holders, in order to
comply with the provisions of the Act, so as to permit a public offering and
sale of their respective Warrant Securities for nine (9) consecutive months by
such Holders and any other holders of the Warrants and/or Warrant Securities who
notify the Company within ten (10) days after receiving notice from the Company
of such request.

    (2) The Company covenants and agrees to give written notice of any
registration request under this Section (i) by any Holder or Holders to all
other registered Holders of the Warrants and the Warrant Securities within ten
(10) days from the date of the receipt of any such registration request.

    (3) In addition to the registration rights under this Section (i) at any
time commencing one year after the effective date of the registration statement
and expiring four (4) years thereafter, the Holders of Representative's Warrants
and/or Warrant Securities shall have the right, exercisable by written request
to the Company, to have the Company prepare and file, on one occasion, with the
Commission a registration statement so as to permit a public offering and sale
for nine (9) consecutive months by such Holders of its Warrant Securities;
provided, however, that


                                       5
<PAGE>   6
the provisions of Section (i)(2) hereof shall not apply to any such registration
request and registration and all costs incident thereto shall be at the expense
of the Holder or Holders making such request.


(j) Covenants of the Company With Respect to Registration. In connection with
any registration under Section (h) or (i) hereof, the Company covenants and
agrees as follows:

    (i) The Company shall use its best efforts to file a registration statement
within sixty (60) days of receipt of any demand therefor, shall use its best
efforts to have any registration statement declared effective at the earliest
possible time, and shall furnish each Holder desiring to sell Warrant Securities
such number of prospectuses as shall reasonably be requested.

    (ii) The Company shall pay all costs (excluding fees and expenses of
Holder(s)' counsel and any underwriting or selling commissions), fees and
expenses in connection with all registration statements filed pursuant to
Sections (h), (i) and (j) hereof including, without limitation, the Company's
legal and accounting fees, printing expenses, blue sky fees and expenses. If the
Company shall fail to comply with the provisions of Section (j)(i), the Company
shall, in addition to any other equitable or other relief available to the
Holder(s), extend the Exercise Period by such number of days as shall equal the
delay caused by the Company's failure.

    (iii) The Company will take all necessary action which may be required in
qualifying or registering the Warrant Securities included in a registration
statement for offering and sale under the securities or blue sky laws of such
states as are reasonably requested by the Holder(s), provided that the Company
shall not be obligated to execute or file any general consent to service of
process or to qualify as a foreign corporation to do business under the laws of
any such jurisdiction.

    (iv) The Company shall indemnify the Holder(s) of the Warrant Securities to
be sold pursuant to any registration statement and each person, if any, who
controls such Holders within the meaning of Section 15 of the Act or Section
20(a) of the Securities Exchange Act of 1934, as amended ("Exchange Act"), from
and against all loss, claim, damage, expense or liability (including all
expenses reasonably incurred in investigating, preparing or defending against
any claim whatsoever) to which any of them may become subject under the Act, the
Exchange Act or otherwise, arising from such registration statement but only to
the same extent and with the same effect as the provisions pursuant to which the
Company has agreed to indemnify the Underwriter contained in Section 7 of the
Underwriting Agreement relating to the offering.

    (v) The Holder(s) of the Warrant Securities to be sold pursuant to a
registration statement, and their successors and assigns, shall severally, and
not jointly, indemnify the Company, its officers and directors and each person,
if any, who controls the Company within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act, against all loss, claim, damage or expense or
liability (including all expenses reasonably incurred in investigating,
preparing or defending against any claim whatsoever) to which they may become
subject under the Act, the Exchange Act or otherwise, arising from information
furnished by or on behalf of such Holders, or their successors or assigns, for
specific inclusion in such registration statement to the same extent with the
same effect as the provisions contained in Section 7 of the Underwriting
Agreement pursuant to which the Underwriter has agreed to indemnify the Company.

    (vi) The Holder(s) may exercise their Warrants prior to the initial
filing of any registration statement or the effectiveness thereof.



    (vii)The Company shall not permit the inclusion of any securities other than
the Warrant Securities to be included in any registration statement filed
pursuant to Section (i) hereof, or permit any other registration statement to be
or remain effective during the effectiveness of a registration statement filed
pursuant to Section (i) hereof, other than a secondary offering of equity
securities of the Company, without the prior written consent of the Holders of
the Warrants and Warrant Securities representing a Majority of such securities
(assuming an exercise of all the Warrants underlying the Warrants).


                                       6
<PAGE>   7
    (viii) The Company shall furnish to each Holder participating in the
offering and to each underwriter, if any, a signed counterpart, addressed to
such Holder or underwriter, of (x) an opinion of counsel to the Company, dated
the effective date of such registration statement (and, if such registration
includes an underwritten public offering, an opinion dated the date of the
closing under the underwriting agreement), and (y) a "cold comfort" letter dated
the effective date of such registration statement (and, if such registration
includes an underwritten public offering, a letter dated the date of the closing
under the underwriting agreement) signed by the independent public accountants
who have issued a report on the Company's financial statements included in such
registration statement, in each case covering substantially the same matters
with respect to such registration statement (and the prospectus included
therein) and, in the case of such accountants' letter, with respect to events
subsequent to the date of such financial statements, as are customarily covered
in opinions of issuer's counsel and in accountants' letters delivered to
underwriters in underwritten public offerings of securities.

    (ix) The Company shall as soon as practicable after the effective date of
the registration statement, and in any event within 15 months thereafter, make
"generally available to its security holders" (within the meaning of Rule 158
under the Act) an earnings statement (which need not be audited) complying with
Section 11(a) of the Act and covering a period of at least 12 consecutive months
beginning after the effective date of the registration statement.

    (x) The Company shall deliver promptly to each Holder participating in the
offering requesting the correspondence and memoranda described below and to the
managing underwriters, copies of all correspondence between the Commission and
the Company, its counsel or auditors and all memoranda relating to discussions
with the Commission or its staff with respect to the registration statement and
permit each Holder and underwriter to do such investigation, upon reasonable
advance notice, with respect to information contained in or omitted from the
registration statement as it deems reasonably necessary to comply with
applicable securities laws or rules of the National Association of Securities
Dealers, Inc. ("NASD") or an Exchange. Such investigation shall include access
to books, records and properties and opportunities to discuss the business of
the Company with its officers and independent auditors, all to such reasonable
extent and at such reasonable times and as often as any such Holder or
underwriter shall reasonably request.

    (xi) The Company shall enter into an underwriting agreement with the
managing underwriters, which may be the Underwriter. Such agreement shall be
satisfactory in form and substance to the Company, and such managing
underwriters, and shall contain such representations, warranties and covenants
by the Company and such other terms as are customarily contained in agreements
of that type used by the managing underwriter; provided however, that no Holder
shall be required to make any representations, warranties or covenants or grant
any indemnity to which it shall object in any such underwriting agreement. The
Holders shall be parties to any underwriting agreement relating to an
underwritten sale of their Warrant Securities and may, at their option, require
that any or all the representations, warranties and covenants of the Company to
or for the benefit of such underwriters shall also be made to and for the
benefit of such Holders. Such Holders shall not be required to make any
representations or warranties to or agreements with the Company or the
underwriters except as they may relate to such Holders and their intended
methods of distribution.

    (xii)For purposes of this Agreement, the term " Majority" in reference to
the Holders of Warrants or Warrant Securities, shall mean in excess of fifty
(50%) of the then outstanding Warrants and Warrant Securities that (i) are not
held by the Company, an affiliate, officer, creditor, employee or agent thereof
or any of their respective affiliates, members of their family, persons acting
as nominees or in conjunction therewith or (ii) have not been resold to the
public pursuant to a registration statement filed with the Commission under the
Act.

(k) Conditions of Company's Obligations. The Company's obligation under Section
j hereof shall be conditioned as to each such public offering, upon a timely
receipt by the Company in writing of:

      (A) Information as to the terms of such public offering furnished by or on
behalf of the Holders making a public distribution of their Warrant Securities;
and


                                       7
<PAGE>   8
    (B) Such other information as the Company may reasonably require from such
Holder, or any underwriter for any of them, for inclusion in such registration
statement or offering statement or post-effective amendment.

    (C) An agreement by the Holder to sell his Warrants and Warrant Securities
on the basis provided in the Underwriting Agreement.
    (1) Continuing Effect of Agreement. The Company's agreements with respect
to the Warrant Securities in this Warrant will continue in effect regardless of
the exercise or surrender of this Warrant.

    (m) Notices. Any notices or certificates by the Company to the Holder and by
the Holder to the Company shall be deemed delivered if in writing and delivered
personally or sent by certified mail, to the Holder, addressed to him or sent
to, Schneider Securities, Inc. 1120 Lincoln Street, Denver, CO 80203, or, if the
Holder has designated, by notice in writing to the Company, any other address,
to such other address, and, if to the Company, addressed to Anthony J. Armini,
President, Implant Sciences Corporation, 107 Audubon Road #5, Wakefield, MA
01880. The Company may change its address by written notice to Schneider
Securities, Inc.

    (n) Limited Transferability. This Warrant Certificate and the Warrant may
not be sold, transferred, assigned or hypothecated for a one-year period after
the effective date of the Registration Statement except to underwriters of the
Offering referred to in the Underwriting Agreement or to individuals who are
either partners or officers of such an underwriter or by will or by operation of
law. The Warrant may be divided or combined, upon request to the Company by the
Warrant holder, into a certificate or certificates evidencing the same aggregate
number of Warrants. The Warrant may not be offered, sold, transferred, pledged
or hypothecated in the absence of any effective registration statement as to
such Warrant filed under the Act, or an exemption from the requirement of such
registration, and compliance with the applicable federal and state securities
laws. The Company may require an opinion of counsel satisfactory to the Company
that such registration is not required and that such laws are complied with. The
Company may treat the registered holder of this Warrant as he or it appears on
the Company's book at any time as the Holder for all purposes. The Company shall
permit the Holder or his duly authorized attorney, upon written request during
ordinary business hours, to inspect and copy or make extracts from its books
showing the registered holders of Warrants.

    (o) Transfer to Comply With the Securities Act of 1933. The Company may
cause the following legend, or one similar thereto, to be set forth on the
Warrants and on each certificate representing Warrant Securities, or any other
security issued or issuable upon exercise of this Warrant not theretofore
distributed to the public or sold to underwriters for distribution to the public
pursuant to Sections (h) or (i) hereof; unless counsel satisfactory to the
Company is of the opinion as to any such certificate that such legend, or one
similar thereto, is unnecessary:

    The warrants represented by this certificate are restricted securities and
may not be offered for sale, sold OR otherwise transferred unless an opinion of

Ladies and Gentlemen:

         We are familiar with the Registration Statement on Form SB-2,
Registration No. 333-64499 filed by Implant Sciences Corporation, a
Massachusetts corporation (the "Company"), with the Securities and Exchange
Commission under the Securities Act of 1933, as amended (the "Registration
Statement"). The Registration Statement relates to the proposed public offering
by the Company of 1,150,000 Units (the "Units") to be issued by the Company.
Each Unit consists of one share of Common Stock, $0.10 par value per share
("Common Stock"), and one Redeemable Common Stock Purchase Warrant ("Warrants").
(The foregoing number of Units assumes exercise in full of the over-allotment
option described in the Registration Statement.)

         We are familiar with the Company's Articles of Organization and all
amendments thereto, its By-Laws and all amendments thereto, records of meetings
and consents of its Board of Directors and of its stockholders provided to us by
the Company, and its stock records. In addition, we have examined and relied on
the originals or copies certified or otherwise identified to our satisfaction of
all such corporate records of the Company and such other instruments and other
certificates of public officials, officers and representatives of the Company
and such other persons, and we have made such investigations of law, as we have
deemed appropriate as a basis for the opinions expressed below.

         Based on the foregoing, it is our opinion that the Company has
corporate power adequate for the issuance of the Units in accordance with the
Registration Statement. The Company has taken all necessary corporate action
required to authorize the issuance and sale of the Units. When certificates for
the Units have been duly executed and countersigned, and delivered against due
receipt of consideration therefor as described in the Registration Statement,
the Units will be legally issued, fully paid and non-assessable.

                  the Company and shall bear a facsimile of the Company's
                  corporate seal. If any person, whose facsimile signature has
                  been placed upon any Unit Certificate as the signature of an
                  officer of the Company, shall have ceased to be such officer
                  before such Unit Certificate is countersigned, issued and
                  delivered, such Unit Certificate shall be countersigned,
                  issued and delivered with the same effect as if such person
                  had not ceased to be such officer. Any Unit Certificate may be
                  signed by, or made to bear the facsimile signature of, any
                  person who at the actual date of the preparation of such Unit
                  Certificate shall be a proper officer of the Company to sign
                  such Unit Certificate even though such person was not such an
                  officer upon the date of the Agreement.

                           The Warrant Certificates shall be in registered form
                  only and shall be substantially in the form set forth in
                  Exhibit B attached to this Agreement. Warrant Certificates
                  shall be signed by, or shall bear the facsimile signature of,
                  the President or a Vice President of the Company and the
                  Treasurer or an Assistant Treasurer of the Company and shall
                  bear a facsimile of the Company's corporate seal. If any
                  person, whose facsimile signature has been placed upon any
                  Warrant Certificate as the signature of an officer of the
                  Company, shall have ceased to be such officer before such
                  Warrant Certificate is countersigned, issued and delivered,
                  such Warrant Certificate shall be countersigned, issued and
                  delivered with the same effect as if such person had not
                  ceased to be such officer. Any Warrant Certificate may be
                  signed by, or made to bear the facsimile signature of, any
                  person who at the actual date of the preparation of such
                  Warrant Certificate shall be a proper officer of the Company
                  to


                                        4
<PAGE>   5
                  sign such Warrant Certificate even though such person was not
                  such an officer upon the date of the Agreement.

                           The Company shall furnish the Agent with a sufficient
                  quantity of blank Certificates and from time to time will
                  renew such supply upon the reasonable request of the Agent.
                  Such blank Certificates shall be properly signed by officers
                  of the Company authorized by law and in accordance with the
                  Company's by-laws to sign such Certificates and, if requested
                  by the Agent, shall bear the corporate seal or a facsimile
                  thereof.

                           Unit Certificates and Warrant Certificates are
                  sometimes hereinafter referred to collectively as
                  "Certificates." The holder of a Certificate is referred to
                  herein as a "Holder".

         6.       Countersigning. Certificates shall be manually countersigned
                  by the Agent and shall not be valid for any purpose unless so
                  countersigned. The Agent hereby is authorized to countersign
                  and deliver to, or in accordance with the proper instructions
                  of, any Unit Holder or Warrant Holder any Certificate which is
                  properly issued.

         7.       Registration of Transfer and Exchanges. Subject to this
                  Agreement including, without limitation, Sections 1 and 2, the
                  Agent shall from time to time register the transfer of any
                  outstanding Certificate upon records maintained by the Agent
                  for such


                                        5
<PAGE>   6
                  purpose upon surrender of such Certificate to the Agent for
                  transfer, accompanied by appropriate instruments of transfer
                  in form satisfactory to the Company and the Agent and duly
                  executed by the Holder or a duly authorized attorney. Upon any
                  such registration of transfer, a new Certificate or
                  Certificates shall be issued in the name of and to the
                  transferee and the surrendered Certificate shall be canceled.

         8.       Exercise and Redemption of Warrants.

                  (a)      Subject to this Agreement including, without
                           limitation, Sections 8(i), 12 and 13, any one Warrant
                           or any multiple of one Warrant evidenced by any
                           Warrant Certificate may be exercised upon any single
                           occasion on or after the Exercise Date, and on or
                           before the Expiration Date (as more particularly set
                           forth in Section 4). A Warrant shall be exercised by
                           the Warrant Holder by surrendering to the Agent the
                           Warrant Certificate evidencing such Warrant with the
                           exercise form on the reverse of such Warrant
                           Certificate duly completed and executed and
                           delivering to the Agent, by good check or bank draft
                           payable to the order of the Company, the Exercise
                           Price for each Share to be purchased.

                  (b)      Upon receipt of a Warrant Certificate with the
                           exercise form thereon duly executed together with
                           payment in full of the Exercise Price for the Shares
                           for which Warrants are then being exercised, the
                           Agent shall requisition from any transfer agent for
                           the Shares, and upon receipt shall make delivery of,
                           certificates evidencing the total number of whole
                           Shares for which Warrants


                                        6

                           are then being exercised in such names and
                           denominations as are required for delivery to, or in
                           accordance with the instructions of, the Warrant
                           Holder. Such certificates for the Shares shall be
                           deemed to be issued, and the person to whom such
                           Shares are issued of record shall be deemed to have
                           become a holder of record of such Shares, as of the
                           date of the surrender of such Warrant Certificate and
                           payment of the Exercise Price, whichever shall last
                           occur; provided that if the books of the Company with
                           respect to the Shares shall be deemed to be closed,
                           the person to whom such Shares are issued of record
                           shall be deemed to have become a record holder of
                           such Shares, as of the date on which such books shall
                           next be open (whether before, on or after the
                           Expiration Date), whichever shall have last occurred.

                  (c)      If less than all the Warrants evidenced by a Warrant
                           Certificate are exercised upon a single occasion, a
                           new Warrant Certificate for the balance of the
                           Warrants not so exercised shall be issued and
                           delivered to, or in accordance with, transfer
                           instructions properly given by the Warrant Holder
                           until the Expiration Date.

                  (d)      All Warrant Certificates surrendered upon exercise of
                           the Warrants shall be canceled and shall not be
                           reissued.

                  (e)      Upon the exercise of any Warrant, the Agent shall
                           promptly deposit the payment into an escrow account
                           established by mutual agreement of the Company and
                           the Agent at a federally insured commercial bank. All
                           funds deposited in the escrow account will be
                           disbursed on a weekly basis to the


                                        7

                           Company once they have been determined by the Warrant
                           Agent to be collected funds. Once the funds are
                           determined to be collected, the Warrant Agent shall
                           cause the share certificate(s) representing the
                           exercised Warrants to be issued.

                  (f)      Usual and customary out-of-pocket expenses incurred
                           by American Securities Transfer & Trust, Inc. while
                           acting in the capacity as Agent will be paid by the
                           Company. These expenses, including costs of delivery
                           of Share certificates to the Warrant Holder upon
                           exercise of Warrants, will be deducted from the
                           exercise fee submitted prior to distribution of funds
                           to the Company. A detailed accounting statement
                           relating to the number of Shares exercised, names of
                           registered Warrant Holder(s) and the net amount of
                           exercised funds remitted will be given to the Company
                           with the payment of each exercise amount.

                  (g)      Except as otherwise provided in Section 9 of this
                           Agreement, at the time of exercise of the Warrant(s),
                           the transfer fee is to be paid by the Company. In the
                           event the shareholder must pay the fee and fails to
                           remit same, the fee will be deducted from the
                           proceeds prior to distribution to the Company.

                  (h)      The Company in its sole discretion, may extend the
                           Expiration Date. If the Company elects to do so, it
                           will give not less than 30 days prior written notice
                           of such extension, specifying the date to which the
                           Expiration Date has been extended, to the Agent, the
                           Warrant Holders and to any stock exchange or Self
                           Regulatory Organization on which the Warrants may be
                           listed.

                  (i)      The Company may redeem the Warrants after the
                           Warrants become exercisable, by giving notice to the
                           Agent, if the Common Stock of the Company shall have
                           had a Closing Price (hereinafter defined) of not less
                           than 140% per share of the assumed initial public
                           offering price of the Common Stock included in the
                           Units for a period of 15 consecutive trading days
                           after the Warrants became exercisable. The Company
                           shall pay Warrant Holders $.20 per Warrant for each
                           Warrant not exercised prior to the close of business
                           on the date specified in the notice ("Redemption Call
                           Date"). Whenever the Exercise Price is adjusted
                           pursuant to Section 13, a similar and proportionate
                           adjustment will be made in the redemption price. Such
                           notice shall contain a certification by the Company
                           that the above condition to redemption of the
                           Warrants has been satisfied. Notice of redemption
                           shall be mailed by the Agent to all registered
                           holders of Warrants in accordance with the provisions
                           of Section 20, at least 30 days, but no more than 60
                           days, prior to the Redemption Call Date. The Agent
                           shall mail such notice to all registered holders of
                           Warrants on a date designated by the Company, but in
                           no event shall such designated date be earlier than
                           the fifth business day after the date on which the
                           Agent received notice of the redemption from the
                           Company. The right to exercise the Warrants shall
                           expire at the close of business on the Redemption
                           Call Date. At the time of any such notice or any time
                           after such notice or prior to the Redemption Call
                           Date, the Company may deposit, or cause its nominee
                           to deposit, the aggregate redemption price (the
                           calculation

                           of which shall be certified by the Company or its
                           agents) for disbursal of the monies so deposited upon
                           proper surrender of the Warrants. In the event the
                           Warrant Holder shall not, within three years after
                           the Redemption Call Date, claim the amount deposited
                           for the redemption of the Warrants, the depositary
                           shall upon demand pay over to the Company such
                           unclaimed amounts and shall thereafter be relieved
                           from all responsibility.

                  (j)      As used in this Warrant Agreement, the term "Closing
                           Price" of the shares of Common Stock for a day or
                           days shall mean (i) if the shares of Common Stock are
                           not listed or admitted for trading on a national
                           securities exchange, (A) the closing bid price of the
                           shares of Common Stock in the Nasdaq Small Cap Market
                           (or on the Nasdaq Stock Market, if so quoted) or (B)
                           if the shares of Common Stock are not so quoted, in
                           the over-the-counter market, as reported by the
                           National Quotation Bureau, Inc., or an equivalent
                           generally accepted reporting service, or (ii) if the
                           shares of Common Stock are listed or admitted for
                           trading on a national securities exchange, the last
                           reported sale price regular way, or, in case no such
                           reported sale takes place on such day or days, the
                           reported closing bid price regular way, in either
                           case on the principal national securities exchange on
                           which the shares of Common Stock are listed or
                           admitted for trading.

         9.       Transfer Taxes and Fees. The Company will pay all transfer

<PAGE>   11
                  shall not, however, be required to pay any transfer taxes and
                  fees which may be payable in respect to any transfer involved
                  in any issue of Unit Certificates or Warrant Certificates or
                  in the issue of any certificates of Shares in the name other
                  than that of the Warrant Holder upon the exercise of any
                  Warrant.

         10.      Mutilated or Missing Certificates. On receipt by the Company
                  and the Agent of evidence satisfactory as to the ownership of
                  and the loss, theft, destruction or mutilation of any
                  Certificate, the Company shall execute and the Agent shall
                  countersign and deliver in lieu thereof, a new Certificate
                  representing an equal aggregate number of Units or Warrants as
                  the case may be. In the case of loss, theft or destruction of
                  any Certificate, the Holder requesting issuance of a new
                  Certificate shall be required to secure an indemnity bond from
                  an approved surety bonding company. In the event a Certificate
                  is mutilated, such Certificate shall be surrendered and
                  canceled by the Agent prior to delivery of a new Certificate.
                  Applicants for a substitute Certificate shall also comply with
                  such other regulations and pay such other reasonable charges
                  as the Agent may prescribe.

         11.      Reservation of Shares. For the purpose of enabling the Company
                  to satisfy all obligations to issue Shares upon exercise of
                  Warrants, the Company will at all times reserve and keep
                  available free from preemptive rights, out of the aggregate of
                  its authorized but unissued shares, the full number of Shares
                  which may be issued upon the exercise of the Warrants and such
                  Shares will upon issue be fully paid and


                                       11
<PAGE>   12
                  nonassessable by the Company and free from all taxes, liens,
                  charges and security interests with respect to the issue
                  thereof.

         12.      Governmental Restrictions. If any Shares issuable upon the
                  exercise of Warrants require registration or approval of any
                  governmental authority, the Company will endeavor to secure
                  such registration or approval; provided that in no event shall
                  such Shares be issued, and the Company shall have the
                  authority to suspend the exercise of all Warrants, until such
                  registration or approval shall have been obtained. If any such
                  period of suspension continues past the Expiration Date, all
                  Warrants, the exercise of which have been requested on or
                  prior to the Expiration Date, shall be exercisable upon the
                  removal of such suspension until the close of business on the
                  business day immediately following the expiration of such
                  suspension.

                  Notwithstanding any other provision of this Agreement or of
                  the Warrants to the contrary, the Warrants shall not be
                  exercisable by the holder of any Warrant Certificate (a) if a
                  registration statement covering the issuance of the shares of
                  Common Stock subject to such Warrant is not effective at the
                  time of exercise or an exception from registration not
                  available or (b) if such holder is resident in a jurisdiction
                  under the securities or blue sky laws of which the shares of
                  Common Stock issuable upon exercise of such Warrant
                  Certificate are not registered or qualified or exempt from
                  registration or qualification or in which a current prospectus

                  meeting the requirements of the laws of such jurisdiction
                  cannot be lawfully delivered by or on behalf of the Company.

                  The Company covenants and agrees that it will file a
                  registration statement under the Securities Act, (which
                  registration statement may be the registration statement for
                  the Company's initial public offering), use its best efforts
                  to cause such registration statement to become effective, use
                  its best efforts to keep such registration statement current,
                  if required under the Securities Act, while any of the
                  Warrants are outstanding, and deliver a prospectus which
                  complies with Section 10(a) (3) of the Securities Act to any
                  Holder exercising a Warrant (if so required by the Securities
                  Act).

         13.      Adjustment of Exercise Price, Number of Shares, or Number of
                  Warrants. The Exercise Price, the number and kind of
                  securities purchasable upon the exercise of each Warrant, and
                  the number of Warrants outstanding shall be subject to
                  adjustment from time to time upon the happening of the events
                  enumerated in this Section 13.

                  (a)      In case the Company shall at any time after the date
                           of this Warrant Agreement (i) pay a dividend in
                           shares of Common Stock or other stock of the Company
                           or make a distribution in shares of Common Stock or
                           such other stock to holders of all its outstanding
                           shares of Common Stock, (ii) subdivide the
                           outstanding shares of Common Stock, (iii) combine the
                           outstanding shares of Common Stock into a smaller
                           number of shares of Common Stock, or (iv)

                           Stock other securities of the Company (including any
                           such reclassification in connection with a
                           consolidation or merger in which the Company is the
                           continuing corporation), the number and kind of
                           shares purchasable upon exercise of each Warrant
                           outstanding immediately prior thereto shall be
                           adjusted so that the holder of each Warrant shall be
                           entitled to receive at the same aggregate Warrant
                           Exercise Price the kind and number of shares of
                           Common Stock or other securities of the Company which
                           the holder would have owned or have been entitled to
                           receive after the happening of any of the events
                           described above had such Warrant been exercised in
                           full immediately prior to the earlier of the
                           happening of such event or any record date with
                           respect thereto. In the event of any adjustment of
                           the total number of shares of Common Stock
                           purchasable upon the exercise of the then outstanding
                           Warrants pursuant to this paragraph (a), the Exercise
                           Price shall be adjusted to be the amount resulting
                           from dividing the number of shares of Common Stock
                           (including fractional shares of Common Stock) covered
                           by such Warrant immediately after such adjustment
                           into the total amount payable upon exercise of such
                           Warrant in full immediately prior to such adjustment.
                           An adjustment made pursuant to this paragraph 13(a)
                           shall become effective immediately after the
                           effective date of such event retroactive to the
                           record date, if any, for such event. Such adjustment
                           shall be made successively whenever any event listed
                           above shall occur.

                  (b)      In case the Company shall issue rights, options, or
                           warrants to all holders of its outstanding shares of
                           Common Stock, entitling them (for a period expiring
                           within 45 days after the record date for the
                           determination of stockholders entitled to receive
                           such rights, options, or warrants) to subscribe for
                           or purchase shares of Common Stock (or securities
                           exchangeable for or convertible into shares of Common
                           Stock) at a price per share of Common Stock (or
                           having an exchange or conversion price per share of
                           Common Stock, with respect to a security exchangeable
                           for or convertible into shares of Common Stock) which
                           is less than 95% of the current Market Price per
                           share of Common Stock (as defined in paragraph (d) of
                           Section 13) on such record date, then the Exercise
                           Price shall be adjusted by multiplying the Exercise
                           Price in effect immediately prior to such record date
                           by a fraction, of which the numerator shall be the
                           number of shares of Common Stock outstanding on such
                           record date plus the number of shares of Common Stock
                           which the aggregate offering price of the total
                           number of shares of Common Stock so to be offered (or
                           the aggregate initial exchange or conversion price of
                           the exchangeable or convertible securities to be
                           offered) would purchase at such Market Price and of
                           which the denominator shall be the number of shares
                           of Common Stock outstanding on such record date plus
                           the number of additional shares of Common Stock to be

                           the exchangeable or convertible securities so to be
                           offered are initially exchangeable or convertible).
                           Such adjustment shall become effective at the

                           the extent that shares of Common Stock (or securities
                           exchangeable for or convertible into shares of Common
                           Stock) are not delivered after the expiration of such
                           rights, options, or warrants, the Exercise Price
                           shall be readjusted (but only with respect to
                           Warrants exercised after such expiration) to the
                           Exercise Price which would then be in effect had the
                           adjustments made upon the issuance of such rights,

                           shares of Common Stock) actually issued. In case any
                           subscription price may be paid in a consideration,
                           part or all of which shall be in a form other than
                           cash, the value of such consideration shall be as
                           determined by the Board of Directors of the Company
                           and shall be described in a statement filed with the
                           Warrant Agent. Shares of Common Stock owned by or
                           held for the account of the Company shall not be
                           deemed outstanding for the purpose of any such
                           computation.

                           Exercise Price in effect immediately prior to the
                           record date for the determination of stockholders

                           calculations under this Section 13 shall be made to
                           the nearest cent or to the nearest one-hundredth of a
                           share, as the case may be

                  (f)      Unless the Company shall have exercised its election
                           as provided in paragraph (g) of this Section 13, upon
                           each adjustment of the Exercise Price as a result of
                           the calculations made in paragraphs (b) or (c) of
                           this Section 13, each Warrant outstanding prior to
                           the making of the adjustment in the Exercise Price
                           shall thereafter evidence the right to purchase at
                           the adjusted Exercise Price, that number of shares of
                           Common Stock (calculated to the nearest hundredth)
                           obtained by (i) multiplying the number of shares of
                           Common Stock purchasable upon exercise of a Warrant
                           prior to adjustment of the number of shares of Common
                           Stock by the Exercise Price in effect prior to
                           adjustment of the Exercise Price and (ii) dividing
                           the product so obtained by the Exercise Price in
                           effect after such adjustment of the Exercise Price.

                  (g)      The Company may elect on or after the date of any
                           adjustment of the Exercise Price to adjust the number
                           of Warrants in substitution for any adjustment in the
                           number of shares of Common Stock purchasable upon the
                           exercise of a Warrant as provided in paragraph (f) of
                           this Section 13. Each of the Warrants


                                       18
<PAGE>   19
                           outstanding after such adjustment of the number of
                           Warrants shall be exercisable for one share of Common
                           Stock. Each Warrant held of record prior to such
                           adjustment of the number of Warrants shall become
                           that number of Warrants (calculated to the nearest
                           hundredth) obtained by dividing the Exercise Price in
                           effect prior to adjustment of the Exercise Price by
                           the Exercise Price in effect after adjustment of the
                           Exercise Price. The Company shall cause the Agent to
                           send to each Warrant Holder an announcement of its
                           election to adjust the number of Warrants, indicating
                           the record date for the adjustment, and, if known at
                           the time, the amount of the adjustment to be made.
                           This record date may be the date on which the
                           Exercise Price is adjusted or any day thereafter, but
                           shall be at least ten days later than the date such
                           announcement is sent to the Warrant Holders. Upon
                           each adjustment of the number of Warrants pursuant to
                           this paragraph (g), the Company shall, as promptly as
                           practicable, cause to be distributed to holders of
                           record of Warrant Certificates on such record date
                           Warrant Certificates evidencing, the additional
                           Warrants to which such holders shall be entitled as a
                           result of such adjustment, or at the option of the
                           Company, shall cause to be distributed to such
                           holders of record in substitution and replacement for
                           the Warrant Certificates held by such holders prior
                           to the date of adjustment, and upon surrender thereof
                           if required by the Company, new Warrant Certificates
                           evidencing all the Warrants to which such holders
                           shall be entitled after such adjustment. Warrant
                           Certificates so to be distributed shall be issued,

                           executed, and countersigned in the manner specified
                           in this Agreement (but may bear, at the option of the
                           Company, the adjusted Exercise Price) and shall be
                           registered in the names of the holders of record of
                           Warrant Certificates on the record date specified in
                           the announcement sent to Warrant Holders.

                  (h)      In case of any capital reorganization of the Company,
                           or of any reclassification of the shares of Common
                           Stock (other than a reclassification of the shares of
                           Common Stock referred to in paragraph (a) of this
                           Section 13, or in case of the consolidation of the
                           Company with, or other merger of the Company with, or
                           merger of the Company into, any other corporation
                           (other than a reclassification of the shares of
                           Common Stock referred to in paragraph (a) of this
                           Section 13 or a consolidation or merger which does
                           not result in any reclassification or change of the
                           outstanding shares of Common Stock) or of the sale of
                           the properties and assets of the Company as, or
                           substantially as, an entirety to any other
                           corporation or entity, each Warrant shall after such
                           capital reorganization, reclassification of shares of
                           Common Stock, consolidation, merger or sale, be
                           exercisable, upon the terms and conditions specified
                           in this Warrant Agreement, for the number of shares
                           or other securities, assets, or cash to which a
                           holder of the number of shares of Common Stock
                           purchasable (at the time of such capital
                           reorganization, reclassification of shares of Common
                           stock, consolidation, merger or sale) upon exercise
                           of such Warrant would have been entitled upon such
                           capital reorganization, reclassification of shares of

                           consolidation, merger, or sale; and in any such case,
                           if necessary, the provisions set forth in this
                           Section 13 with respect to the rights and interests
                           thereafter of the holders of the Warrants shall be
                           appropriately adjusted so as to be applicable, as
                           nearly as may reasonably be, to any shares or other
                           securities, assets, or cash thereafter deliverable
                           on the exercise of the Warrants. The subdivision or
                           combination of shares of Common Stock at any time
                           outstanding into a greater or lesser number of shares
                           shall not-be deemed to be a reclassification of the
                           shares of Common Stock for the purposes of this
                           paragraph. The Company shall not effect any such
                           consolidation, merger, or sale, unless prior to or
                           simultaneously with the consummation thereof the
                           successor corporation or entity (if other than the
                           Company) resulting from such consolidation or merger
                           or the corporation or entity purchasing such assets
                           or other appropriate corporation or entity shall
                           assume, by written instrument executed and delivered
                           to, and in form reasonably acceptable to, the Warrant
                           Agent, the obligations to deliver to the holder of
                           each Warrant such shares, securities, assets, or cash
                           as, in accordance with the foregoing provisions, such
                           holders may be entitled to purchase and the other
                           obligations under this Warrant Agreement.

                  (i)      In the event that at any time, as a result of an
                           adjustment made pursuant to this Section 13 the
                           holders of a Warrant or Warrants shall become
                           entitled to purchase any shares or securities of the
                           Company other than the shares of Common Stock,
                           thereafter the number of such other shares or
                           securities so

<PAGE>   22
                           purchasable upon exercise of each Warrant and the
                           Exercise Price for such shares or securities shall be
                           subject to adjustment from time to time in a manner
                           and on terms as nearly equivalent as practicable to
                           the provisions with respect to the shares of Common
                           Stock contained in paragraphs (a) through (h) of
                           Section 13, inclusive, and the other provisions of
                           this Agreement, with respect to the shares of Common
                           Stock shall apply on like terms to any such other
                           shares.

                  (j)      In any case in which this Section 13 shall require
                           that an adjustment in the Exercise Price be made
                           effective as of a record date for a specified event,
                           the Company may elect to defer until the occurrence
                           of such event issuing to the holder of any Warrant
                           exercised after such record date the shares of Common
                           Stock if any, issuable upon exercise over and above
                           the shares of Common Stock, if any, issuable upon
                           such exercise on the basis of the Exercise Price in
                           effect prior to such adjustment; provided, however,
                           that the Warrant Agent shall deliver as soon as
                           practicable to such holder a due bill or other
                           appropriate instrument provided by the Company and in
                           form acceptable to the Warrant Agent, evidencing such
                           holder's right to receive such additional shares of
                           Common Stock upon the occurrence of the event
                           requiring such adjustment.

         14.      Notice to Warrant Holders. Upon any adjustment as described in
                  Section 13, the Company within 20 business days thereafter
                  shall (i) cause to be filed with the Agent


                                       22
<PAGE>   23
                  a certificate signed by a Company officer setting forth the
                  details of such adjustment, the method of calculation and the
                  facts upon which such calculation is based, which certificate
                  shall be conclusive evidence of the correctness of the matters
                  set forth therein, and (ii) cause written notice of such
                  adjustments to be given to each Warrant Holder (or Unit
                  Holders, if prior to the Separation Date) as of the record
                  date applicable to such adjustment. Also, if the Company
                  proposes to enter into any reorganization, reclassification,
                  sale of substantially all of its assets, consolidation,
                  merger, dissolution, liquidation or winding up, the Company
                  shall give notice of such fact at least 20 days prior to the
                  consummation of such action to all Warrant Holders (or Unit
                  Holders, if prior to the Separation Date) which notice shall
                  set forth such facts as indicate the effect of such action (to
                  the extent such effect may be known at the date of such
                  notice) on the Exercise Price and the kind and amount of the
                  shares or other securities and property deliverable upon
                  exercise of the Warrants. Without limiting the obligation of
                  the Company hereunder to provide notice to each Warrant Holder
                  (or Unit Holder, if prior to the Separation Date), failure of
                  the Company to give notice shall not invalidate any corporate
                  action taken by the Company.

         15.      No Fractional Warrants or Shares. The Company shall not be
                  required to issue fractions of Warrants upon the reissue of
                  Warrants, any adjustments as described in Section 13 or
                  otherwise; but the Company in lieu of issuing any such
                  fractional interest, shall round up or down to the nearest
                  full Warrant. If the total Warrants surrendered by exercise
                  would result in the issuance of a fractional share, the


                                       23
<PAGE>   24
                  Company shall not be required to issue a fractional share but
                  rather the aggregate number of shares issuable will be rounded
                  up or down to the nearest full share.

         16.      Rights of Warrant Holders. No Warrant Holder, as such, shall
                  have any rights of a shareholder of the Company, either at law
                  or equity, and the rights of the Warrant Holders, as such, are
                  limited to those rights expressly provided in this Agreement
                  or in the Warrant Certificates. The Company and the Agent may
                  treat the registered Warrant Holder in respect of any Warrant
                  Certificates as the absolute owner thereof for all purposes
                  notwithstanding any notice to the contrary.

         17.      Agent. The Company hereby appoints the Agent to act as the
                  agent of the Company and the Agent hereby accepts such
                  appointment upon all of the terms and conditions set forth in
                  this Agreement including, without limitation, the following
                  terms and conditions by all of which the Company and every
                  Unit Holder and Warrant Holder, by acceptance of his Units or
                  Warrants, shall be bound:

                  (a)      Statements contained in this Agreement and in the
                           Certificates shall be taken as statements of the
                           Company. The Agent assumes no responsibility for the
                           correctness of any of the same except such as
                           describes the Agent or for action taken or to be
                           taken by the Agent.

                  (b)      The Agent shall not be responsible for any failure of
                           the Company to comply with any of the Company's
                           covenants contained in this Agreement or in the
                           Warrant Certificates.

                  (c)      The Agent may consult at any time with counsel
                           satisfactory to it (who may be counsel for the
                           Company) and the Agent shall incur no liability or
                           responsibility to the Company or to any Unit Holder
                           or Warrant Holder in respect of any action taken,
                           suffered or omitted by it hereunder in good faith and
                           in accordance with the opinion or the advice of such
                           counsel; provided the Agent shall have exercised
                           reasonable care in the selection and continued
                           employment of such counsel.

                  (d)      The Agent shall incur no liability or responsibility
                           to the Company or to any Unit Holder or Warrant
                           Holder for any action taken in reliance upon any
                           notice, resolution, waiver, consent, order,
                           certificate or other paper, document or instrument
                           believed by it to be genuine and to have been signed,
                           sent or presented by the proper party or parties.

                  (e)      The Company agrees to pay to the Agent compensation
                           for all services rendered by the Agent in the
                           execution of this Agreement in accordance with the
                           fee schedule attached in Exhibit C hereto, to
                           reimburse the Agent for all reasonable out-of-pocket
                           expenses, taxes and governmental charges and all
                           other charges of any kind or nature incurred by the
                           Agent in the execution of this Agreement and to
                           indemnify the Agent and save it harmless against any
                           and all liabilities, including judgments, costs and
                           reasonable counsel fees, for this Agreement except
                           those costs and fees arising as a result of the
                           Agent's negligence or bad faith.

                  (f)      The Agent shall be under no obligation to institute
                           any action, suit or legal proceeding or to take any
                           other action likely to involve expense unless the
                           Company or one or more Unit Holders or Warrant
                           Holders shall furnish the Agent with reasonable
                           security and indemnity for any costs and expenses
                           which may be incurred in connection with such action,
                           suit or legal proceeding, but this provision shall
                           not affect the power of the Agent to take such action
                           as the Agent may consider proper, whether with or
                           without any such security or indemnity. All rights of
                           action under this Agreement or under any of the
                           Warrants may be enforced by the Agent without the
                           possession of any of the Warrant Certificates or the
                           production thereof at any trial or other proceeding
                           relative thereto, and any such action, suit or
                           proceeding instituted by the Agent shall be brought
                           in its name as Agent, and any recovery of judgement
                           shall be for the ratable benefit of the Unit Holders
                           or Warrant Holders, as the case may be, as their
                           respective rights or interest may appear.

                  (g)      The Agent and any shareholder, director, officer or
                           employee of the Agent may buy, sell or deal in any of
                           the Units or Warrants or other securities of the
                           Company or become pecuniarily interested in any
                           transaction in which the Company may be interested,
                           or contract with or lend money to the Company or
                           otherwise act as fully and freely as though it were
                           not Agent under this Agreement. Nothing herein shall
                           preclude the Agent from acting in any other capacity
                           for the Company or for any other legal entity.

                  (h)      At any time the Agent may apply to the Company or its
                           counsel for instructions or information, and may
                           consult with its own counsel, with respect to any
                           matter arising in connection with the agency created
                           hereby and the Agent shall not be liable for any
                           action taken or omitted in accordance with such
                           instructions, information or the advice or opinion of
                           such officer or counsel. The Agent shall not be
                           liable for acting upon any paper or document believed
                           by it to be genuine and to have been signed by the
                           proper person(s). The Agent shall also not be liable
                           for recognizing stock certificates which it
                           reasonably believes bear the proper manual or
                           facsimile signatures of the officers of the Company
                           and the proper counter-signature of a transfer agent
                           or registrar, or of a co-transfer agent or
                           co-registrar. The Agent, if it so elects, may rely
                           conclusively, for any and all purposes, upon any
                           advice or transfer or transfers made in the course of
                           transferring or registering original issuances,
                           retirements or cancellation of Units or Warrants;
                           upon advice of stop transfer orders placed, released
                           or in effect against outstanding Certificates; and
                           upon any certification or notification as to the
                           number of Certificates issued, the Certificates
                           representing such Units or Warrants and other
                           information which the Agent may receive from time to
                           time from any co-transfer agent or co-registrar. The
                           Agent shall further not be liable for relying upon
                           all information contained in Certification of
                           Corporate Secretary or otherwise supplied to the
                           Agent by the Company in accordance with the terms of
                           this Agreement. The Agent may deliver to the Company
                           from time


                                       27
<PAGE>   28
                           to time at its discretion, for safekeeping or
                           disposition by the Company in accordance with law,
                           such records, papers, stock certificates which have
                           been cancelled in transfer or exchanges and other
                           documents accumulated in the execution of its duties
                           hereunder as the Agent may deem expedient, other than
                           those which the Agent is itself required to maintain
                           pursuant to applicable laws and regulations. Upon
                           delivery of such records, the Company shall assume
                           all responsibility for any failure thereafter to
                           produce any record, paper, cancelled stock
                           certificate or other document so returned, if and
                           when required. The Agent will endeavor to notify the
                           Company of, and will follow instructions received
                           from the Company with respect to, any request or
                           demand for the inspection of the Company's books.
                           However, the Agent reserves the right to exhibit the
                           records to any person if it is advised by its counsel
                           that it may be held liable for the failure to exhibit
                           such records to such person.

         18.      Successor Agent. Any corporation into which the Agent may be
                  merged or converted or with which it may be consolidated, or
                  any corporation resulting from any merger, conversion or
                  consolidation to which the Agent shall be a party, or any
                  corporation succeeding to the corporate trust business of the
                  Agent, shall be the successor to the Agent hereunder without
                  the execution or filing of any paper or any further act of a
                  party or the parties hereto. In any such event or if the name
                  of the Agent is changed, the Agent or such successor may adopt
                  the countersignature of the original Agent and


                                       28
<PAGE>   29
                  may countersign Certificates either in the name of the
                  predecessor Agent or in the name of the successor Agent.

         19.      Change of Agent. The Agent may resign or be discharged by the
                  Company from its duties under this Agreement, by the Agent or
                  the Company, as the case may be, giving notice in writing to
                  the other, and by giving a date when such resignation or
                  discharge shall take effect, which notice shall be sent at
                  least 30 days prior to the date so specified. If the Agent
                  shall resign, be discharged or shall otherwise become
                  incapable of acting, the Company shall appoint a successor to
                  the Agent. If the Company shall fail to make such appointment
                  within a period of 30 days after it has been notified in
                  writing of such resignation or incapacity by the Agent after
                  discharging the Agent, then any Unit Holder or Warrant Holder
                  may apply to the District Court for Denver County, Colorado,
                  for the appointment of a successor to the Agent. Pending
                  appointment of a successor to the Agent, either by the Company
                  or by such Court, the duties of the Agent shall be carried out
                  by the Company. Any successor Agent, whether appointed by the
                  Company or by such Court, shall be a bank or a trust company,
                  in good standing, organized under the laws of any State of the
                  United States of America, and having at the time of its
                  appointment as Agent, a combined capital and surplus of at
                  least four million dollars. After appointment, the successor
                  Agent shall be vested with the same powers, rights, duties and
                  responsibilities as if it had been originally named as Agent
                  without further act or deed and the former Agent shall deliver
                  and transfer to the successor Agent any property at the time
                  held by it


                                       29
<PAGE>   30
                  thereunder, and execute and deliver any further assurance,
                  conveyance, act or deed necessary for effecting the delivery
                  or transfer. Failure to give any notice provided for in this
                  section, however, or any defect therein, shall not affect the
                  legality or validity of the resignation or removal of the
                  Agent or the appointment of the successor Agent, as the case
                  may be.

         20.      Notices. Any notice or demand authorized by this Agreement to
                  be given or made by the Agent or by any Unit Holder or Warrant
                  Holder to or on the Company shall be sufficiently given or
                  made if sent by mail, first class, certified or registered,
                  postage prepaid, addressed (until another address is filed in
                  writing by the Company with the Agent), as follows:

                                    Attn: Dave Broadwin, Esq.


                  Any notice or demand authorized by this Agreement to be given
                  or made by any Unit Holder, Warrant Holder or by the Company
                  to or on the Agent shall be sufficiently given or made if sent
                  by mail, first class, certified or registered, postage
                  prepaid,


                                       30
<PAGE>   31
                  addressed (until another address is filed in writing by the
                  Agent with the Company), as follows:

                                    American Securities Transfer & Trust, Inc.
                                    1825 Lawrence Street, Suite 444
                                    Denver, CO 80202-1817


                  Any distribution, notice or demand required or authorized by
                  this Agreement to be given or made by the Company or the Agent
                  to or on the Unit Holders or Warrant Holders shall be
                  sufficiently given or made if sent by mail, first class,
                  certified or registered, postage prepaid, addressed to the
                  Unit Holders or Warrant Holders at their last known addresses
                  as they shall appear on the registration books for the
                  Certificates maintained by the Agent.

         21.      Supplements and Amendments. The Company and the Agent may make
                  such modifications to this Agreement and to the Warrants that
                  they deem necessary and desirable that do not materially
                  adversely affect the interests of the Unit Holders and Warrant
                  Holders. No other modifications may be made to the Units and
                  Warrants without the consent of the majority of the Unit
                  Holders and Warrant Holders, respectively. Reduction of the
                  number of securities purchasable upon the exercise of any
                  Warrant, increase in the exercise price and shortening of the
                  expiration date with respect to any Warrant requires the
                  consent of the holder of such Warrant unless such modification
                  occurs in connection with a stock split, stock dividend,
                  recapitalization, reclassification or similar event.

         22.      Successors. All the covenants and provisions of this Agreement
                  by or for the benefit of the Company or the Agent shall bind
                  and inure to the benefit of their respective successors and
                  assigns hereunder.

         23.      Termination. This Agreement shall terminate at the close of
                  business on the Expiration Date or such earlier date upon
                  which all Warrants have been exercised or redeemed; provided,
                  however, that if exercise of the Warrants is suspended
                  pursuant to Section 12 and such suspension continues past the
                  Expiration Date, this Agreement shall terminate at the close
                  of business on the business day immediately following
                  expiration of such suspension. The provisions of Section 17
                  shall survive such termination.

         24.      Governing Law. This Agreement and each Certificate issued
                  hereunder shall be deemed to be a contract made under the laws
                  of the State of New York and for all purposes shall be
                  construed in accordance with the laws of said State.

         25.      Benefits of this Agreement. Nothing in this Agreement shall be
                  construed to give any person or corporation other than the
                  Company, the Agent and the Unit Holders and Warrant Holders
                  any legal or equitable right, remedy or claim under this
                  Agreement; but this Agreement shall be for the sole and
                  exclusive benefit of the Company, the Agent and the Unit

force and effect as if they were given in full text. Upon request, the
Contracting Officer will make their full text available. Also, the full text of
a clause may be accessed electronically at this/these address(es):

- ------------------------------------


252.227-7036   DECLARATION OF TECHNICAL DATA CONFORMITY (JAN 1997)

All technical data delivered under this contract shall be accompanied by the
following written declaration:

The Contractor, __________________, hereby declares that, to the best of its
knowledge and belief, the technical data delivered herewith under Contract No.
____________ is complete, accurate, and complies with all requirements of the
contract.

Date_______________________________

252.232-7007   LIMITATION OF GOVERNMENT'S OBLIGATION (AUG 1993)

(a) Contract line item(s) 0001 through 0002 are incrementally funded. For these
item(s), the sum of $95,000 of the total price is presently available for
payment and allotted to this contract. An allotment schedule is set forth in
paragraph (i) of this clause.

(b) For item(s) identified in paragraph (a) of this clause, the Contractor
agrees to perform up to the point at which the total amount payable by the
Government, including reimbursement in the event of termination of those item(s)
for the Government's convenience, approximates the total amount currently
allotted to the contract. The Contractor will not be obligated to continue work
on those item(s) beyond that point. The Government will not be obligated in any
event to reimburse the Contractor in excess of the amount allotted to the
contract for those item(s) regardless of anything to the contrary in the clause
entitled "TERMINATION FOR THE CONVENIENCE OF THE GOVERNMENT." As used in this
clause, the total amount payable by the Government in the event of termination
of applicable contract line item(s) for convenience includes costs, profit and
estimated termination settlement costs for those item(s).

(c) Notwithstanding the dates specified in the allotment schedule in paragraph
(i) of this clause, the Contractor will notify the Contracting Officer in
writing at least NINETY days prior to the date when, in the Contractor's best
judgment, the work will reach the point at which the total amount payable by the
Government, including any cost for termination for convenience, will approximate
85 percent of the total amount then allotted to the contract for performance of
the applicable item(s). The notification will state (1) the estimated date when
that point will be reached and (2) an estimate of additional funding, if any,
needed to continue performance of applicable line items up to the next scheduled
date for allotment of funds identified in paragraph (i) of this clause, or to a
mutually agreed upon substitute date. The notification will also advise the
Contracting Officer of the estimated amount of additional funds that will be
required for the timely performance of the item(s) funded pursuant to this
clause, for subsequent period as may be specified in the allotment schedule in
paragraph (i) of this clause, or otherwise agreed to by the parties. If after
such notification additional funds are not allotted by the date identified in
the Contractor's




                                       13
<PAGE>   13




notification, or by an agreed substitute date, the Contracting Officer will
terminate any item(s) for which additional funds have not been allotted,
pursuant to the clause of this contract entitled "TERMINATION FOR THE
CONVENIENCE OF THE GOVERNMENT."

(d) When additional funds are allotted for continued performance of the contract
line item(s) identified in paragraph (a) of this clause, the parties will agree
as to the period of contract performance which will be covered by the funds. The
provisions of paragraph (b) through (d) of this clause will apply in like manner
to the additional allotted funds and agreed substitute date, and the contract
will be modified accordingly.

(e) If, solely by reason of failure of the Government to allot additional funds,
by the dates indicated below, in amounts sufficient for timely performance of
the contract line item(s) identified in paragraph (a) of this clause, the
Contractor incurs additional costs or is delayed in the performance of the work
under this contract and if additional funds are allotted, an equitable
adjustment will be made in the price or prices (including appropriate target,
billing, and ceiling prices where applicable) of the item(s), or in the time of
delivery, or both. Failure to agree to any such equitable adjustment hereunder
will be a dispute concerning a question of fact within the meaning of the clause
entitled "disputes."

(f) The Government may at any time prior to termination allot additional funds
for the performance of the contract line item(s) identified in paragraph (a) of
this clause.


(g) The termination provisions of this clause do not limit the rights of the
Government under the clause entitled "DEFAULT." The provisions of this clause
are limited to work and allotment of funds for the contract line item(s) set
forth in paragraph (a) of this clause. This clause no longer applies once the
contract if fully funded except with regard to the rights or obligations of the
parties concerning equitable adjustments negotiated under paragraphs (d) or (e)
of this clause.


(h) Nothing in this clause affects the right of the Government to this contract
pursuant to the clause of this contract entitled "TERMINATION FOR CONVENIENCE OF
THE GOVERNMENT."

(i) The parties contemplate that the Government will allot funds to this
contract in accordance with the following schedule:

On execution of contract .............  $95,000
          FY00                          $375,000
          FY01                          $280,000

(End of clause)
