          NOTES TO INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

                                  June 30, 1998


1. General

    The accompanying unaudited interim condensed consolidated financial
    statements include the accounts of Dental/Medical Diagnostic Systems, Inc.
    and Subsidiaries (the "Company"). All significant intercompany accounts and
    transactions have been eliminated in the consolidated financial statements.
    The interim consolidated financial statements have been prepared in
    accordance with generally accepted accounting principles for interim
    financial information and with instructions to Form 10-QSB and Item 10 of
    Regulation S-B. Accordingly, they do not include all of the information and
    footnotes required by generally accepted accounting principles for complete
    financial statements. In the opinion of management, all adjustments
    (consisting of normal recurring accruals) considered necessary for a fair
    representation have been included. Operating results for the six-month
    period ended June 30, 1998 are not necessarily indicative of the results
    that may be expected for the year ending December 31, 1998. For further
    information, refer to the consolidated financial statements and footnotes
    thereto included in the Company's annual report on Form 10-KSB for the
    period ended December 31, 1997.


2. Summary of Significant Accounting Policies


   Concentration of Credit Risk and Major Customers

    Financial instruments that potentially subject the Company to significant
    concentrations of credit risk consist principally of trade accounts
    receivable. Also, at various times throughout the year, cash balances are
    maintained in excess of Federally insured limits.

    For the six-month period ended June 30, 1998 and 1997, international
    customers accounted for 33% and 27% of sales, respectively. At June 30, 1998
    and 1997 international customers accounted for approximately 87% and 69% of
    trade accounts receivable, respectively.

    The Company performs ongoing credit evaluations of its customers' financial
    condition and generally does not require collateral. Estimated credit losses
    and returns have been provided for in the financial statements.

    The majority of the Company's current customers consist of dental
    professionals. Certain of the dental professionals lease the Company's
    products through third party leasing companies. Under the terms of the
    sales, the leasing companies have no recourse against the Company.


   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 at
    the date of the financial statements and the reported amounts of revenues
    and expenses during the reporting period. The significant estimates made in
    the preparation of the consolidated financial statements relate to the
    assessment of the carrying value of accounts receivable, inventories and
    warranty provisions. Actual results could differ from those estimates.



   Risks and Uncertainties

    The Company buys certain key components from one supplier or from a limited
    number of suppliers. Although there are a limited number of suppliers of the
    key components, management believes that other suppliers could provide
    similar components on comparable terms. Changes in key suppliers could cause
    delays in manufacturing and distribution of products and a possible loss in
    sales, which could adversely affect operating results.


                                       7
<PAGE>   8

    The Company has derived substantially all of its revenues from the sales of
    one product family. The Company believes that the inability to attract new
    customers, the loss of one or more of its major customers, a significant
    reduction in business from such customers, or the uncollectibility of
    amounts due from any of its larger customers, could have a material adverse
    affect on the Company.



   Revenue Recognition

    The Company recognizes revenue from the sales of systems and supplies at the
    time of shipment and satisfaction of significant vendor obligations, if any,
    net of an allowance for estimated sales returns. The Company generally
    provides warranties on its systems for one year. A provision for estimated
    future costs relating to warranty is recorded when systems are shipped.



   Cash and Cash Equivalents

    For purposes of the statement of cash flows, the Company considers all
    highly liquid investments purchased with an original maturity of three
    months or less to be cash equivalents.


   Income Taxes

    The Company accounts for income taxes under the liability method. Under this
    method, deferred tax assets and liabilities are determined based on the
    differences between the financial statement and tax bases of assets and
    liabilities, using enacted tax rates in effect for the year in which the
    differences are expected to reverse. Valuation allowances are established
    when necessary to reduce deferred tax assets to the amount expected to be
    realized. Income tax expense is the tax currently payable for the period and
    the change during the period in deferred tax assets and liabilities.

   Computation of Earnings Per Share

    The Company adopted Statement of Financial Accounting Standards (SFAS) No.
    128; "Earnings Per Share" for the year ended December 31, 1997, and has
    reported earnings per common share for all periods presented in accordance
    with the new standard. Net income (loss) per common share is computed by
    dividing net income (loss) by the weighted average number of shares of
    common stock outstanding during the period. Net income (loss) per common
    share assuming dilution is computed by dividing net income (loss) by the
    weighted average number of shares of common stock outstanding plus the
    number of additional common shares that would have been outstanding if all
    dilutive potential common shares had been issued. Potential common shares

   Recently Issued Accounting Standards

    In June 1997, the FASB issued SFAS No. 131, Disclosures about Segments of an
    Enterprise and Related Information. This statement will change the way
    public companies report information about segments of their business in
    their annual financial statements and requires them to report selected
    segment information in their quarterly reports issued to shareholders. It
    also requires entity-wide disclosures about the products and services an
    entity provides, the material countries in which it holds assets and reports
    revenues, and its major customers. The Statement is effective for fiscal
    years beginning after December 15, 1997. Management has not yet determined
    the effect, if any, of SFAS No. 131 on the consolidated financial
    statements.



   Comprehensive Income

    In January 1998, the Company adopted the provisions of Statement of
    Financial Accounting Standards No. 130, "Reporting Comprehensive Income"
    ("SFAS 130"). SFAS 130 establishes standards for reporting and displaying
    comprehensive income and its components (revenues, expenses, gains and
    losses) in financial statements. SFAS 130 requires that all items that are
    required to be recognized under accounting standards as components of
    comprehensive income to be reported in a financial statement that is
    displayed with the same prominence as other financial statements.

    No tax effect has been allocated to the foreign currency translation
    adjustment for the periods presented.

3. Related Party Transactions

    From December 1995 through February 1996, Robert H. Gurevitch, Chairman of
    the Board and Chief Executive Officer of the Company, and Boston Marketing
    Company, Ltd. ("Boston Marketing"), an affiliate of Hiroki Umezaki, a former
    Director of the Company, loaned the Company an aggregate of $377,015. The
    Promissory Notes evidencing such loans bear interest at 6% per annum and
    were originally payable within six months. On February 26, 1996, the Company
    repaid $50,000 to each of Mr. Gurevitch and Boston Marketing. In November
    1996, Mr. Gurevitch and Boston Marketing each agreed to extend the term of
    their respective notes. On May 23, 1997, Boston Marketing was paid the
    remaining principal balance of $150,000 of its loan plus the accrued
    interest of $3,526. Mr. Gurevitch was paid $25,000 on July 10, 1997 and
    $26,850 on October 22, 1997; $5,000 on October 30, 1997; $13,787 on November

</TABLE>

5. Capital Transactions

    On March 2, 1998, the Company entered into an agreement with accredited
    investors and institutional purchasers for the private placement (the "Debt
    Placement") of its 12% Senior Subordinated Notes due 1999 (the "Notes") and
    450,000 warrants (the "1998 Warrants"). The Debt Placement was consummated
    on March 19, 1998. The 1998 Warrants are (i) exercisable commencing on May
    15, 1998, and for five years thereafter for the purchase of one share of
    Common Stock per Warrant; and (ii) at an exercise price of $5.812 per share.
    The Notes (i) bear interest payable semi-annually at a rate of 12% per
    annum; (ii) mature on the first anniversary of the date of issuance; and
    (iii) may be repaid by the Company prior to maturity at one hundred and two
    (102%) percent of the amount of the unpaid principal plus interest due as of
    the date of repayment. As a result of the warrant issuance, the Senior
    Subordinated Notes were discounted by $1,620,225, which will be amortized
    over the term of the Notes. If the Notes are unpaid at maturity, each Note
    holder has the option to convert the outstanding principal and interest then
    due on such Note into Common Stock of the Company (the "Conversion Shares")
    at a conversion price equal to eighty (80%) percent of the average of the
    five lowest closing bid prices for the twenty consecutive trading days prior
    to the date of conversion. The unpaid principal and interest then due on the
    Notes is convertible into a maximum aggregate amount of 500,000 shares of
    Common Stock. Depending on the stock price at the time of conversion, more
    than 500,000 shares of common stock may be required to permit conversion of
    one hundred (100%) percent of the unpaid principal and interest then due on
    the Notes into Common Stock. The Company's stockholders approved issuance of
    a sufficient number of shares of Common Stock to permit conversion upon
    default of one hundred (100%) percent of the unpaid principal and interest
    then due on all of the outstanding Notes to Common Stock at the annual
    stockholders meeting on July 21, 1998.


6. Income Taxes

    Due to the cumulative loss position of the Company, a full valuation
    allowance has been provided against the deferred tax asset, as realization
    is not reasonably assured at this time.



7. Other

    The Company had obtained distribution rights under an agreement with Ion
    Laser Technology, Inc. ("ILT") for a composite curing and whitening device
    under development by ILT. That device, which was similar in many respects to
    the Apollo 95E, was intended to be marketed by the Company as the Apollo
    9500 in the United States and Canada. On May 4, 1998, ILT announced that it
    would not be able to perform its obligations under ILT's agreement with the
    Company. According to the terms of the agreement, ILT repaid the Company
    approximately $500,000 in inventory advances and prepaid license fees. The
    Company now intends to introduce the Apollo 95E into the United States and
    Canada. Shipment of the 95E into the United States requires regulatory
    notification from the Food and Drug Administration and, while no assurance
    of receipt of the required notifications can be given, the Company filed for
    such notification on June 2, 1998 and expects that a period of 60 to 90 days
    will be required to obtain the necessary notification. See "Cautionary
    Statements and Risk Factors -- Extensive Government Regulation."

Item 2. - Management's Discussion and Analysis or Plan of Operation

Introduction

This discussion summarizes the significant factors affecting the consolidated
operating results, financial condition and liquidity/cash flows of the Company
for the three-month and six-month periods ended June 30, 1998 and 1997. Except
for the historical information contained herein, the matters discussed in this
Management's Discussion and Analysis are forward looking statements that involve
risks and uncertainties and are based upon judgments concerning various factors
that are beyond the Company's control. Actual results could differ materially
from those projected in the forward looking statements as a result of, among
other factors, the factors set forth under the caption "Cautionary Statements
and Risk Factors" below.

Dental Medical Diagnostic Systems, Inc. ("Company") designs, develops,
manufactures and sells high technology dental equipment. The Company was
organized in New York in 1981 under the name Edudata Corporation and
reincorporated in Delaware in 1983. The Company was initially organized to
provide education in the use of personal computers, to market software programs
developed by others, and to provide a broad range of advisory services to
businesses in conjunction with both computer and non-computer related management
issues. From 1988 to early 1996, the Company's operations were limited to
exploring opportunities to acquire or to become an operating business.

The Company's primary product emphasis has been on the manufacture and sale of
an intraoral camera system known as the "TeliCam II System," a multi-operatory
intraoral camera system known as the InTELInet, for use in connection with the
TeliCam II System, and a teeth whitening and curing device known as the Apollo
95E which the Company markets internationally. The Company had obtained
distribution rights under an agreement with Ion Laser Technology, Inc. ("ILT")
for a composite curing and whitening device under development by ILT. That
device, which was similar in many respects to the Apollo 95E, was intended to be
marketed by the Company as the Apollo 9500 in the United States and Canada. On
May 4, 1998, ILT announced 


                                       11
<PAGE>   12

that it would not be able to perform its obligations under ILT's agreement with
the Company. The Company now intends to introduce the Apollo 95E into the United
States and Canada. Shipment of the 95E into the United States requires
regulatory notification from the Food and Drug Administration and, while no
assurance of receipt of the required notifications can be given, the Company
filed for such notification on June 2, 1998 and expects that a period of 60 to
90 days will be required to obtain necessary notifications. See "Cautionary
Statements and Risk Factors -- Extensive Government Regulation." The Company has
also developed an updated version of its intraoral camera system, the "TeliCam
Elite" and introduced the updated camera in the second quarter of fiscal year
1998.

The TeliCam II and Elite Systems display close-up color video images of dental
patients' teeth and gums. These TeliCam images assist dentists in displaying
dental health and hygiene problems to patients and, as a result of such display,
promote patient acceptance of treatment plans. The TeliCam II System offers
dentists the ability to capture and display multiple video images without an
expensive external capture device such as a video cassette recorder or color
printer, thereby providing a low-cost alternative to the more expensive
traditional intraoral dental camera systems. The Company commenced shipments of
a predecessor of the TeliCam II System known as the "TeliCam I System" to
customers in February 1996, shipped TeliCam II Systems commencing in the second
quarter of 1997 and shipped Elite Systems in the second quarter of 1998. The
Company believes that the market for intraoral cameras such as the TeliCam II
system is a market which has matured. TeliCam System II and Elite Systems sales
have recently been below levels of prior comparable periods, a trend which the
Company expects to continue.

The Company in the first quarter of 1998 introduced a curing and whitening
device, the Apollo 95E, to markets outside of the U.S. and Canada. The Apollo
95E was developed by S.E.D. Gerant ("S.E.D."), a developer and manufacturer of
medical and dental devices organized under the laws of France which was acquired
by the Company in 1997. The Company believes that the Apollo 95E produces faster
results than products currently available in that market place. This product is
designed to cure composite material in three seconds or less, and to produce
teeth whitening in a dental operatory in less than one hour. The Company will
also market the chemical composite and whitening materials to be used with this
product. See "Cautionary Statements and Risk Factors -- Substantial Dependence
on Third Parties -- Suppliers."

The Company has entered into an agreement with Suni Imaging Microsystems, Inc.
("Suni") to develop digital x-ray technology for incorporation into systems for
the dental market. The Company has obtained exclusive rights to market products
to the dental market incorporating certain digital x-ray technology developed by
Suni. Suni will retain the rights to developed microchip technology underlying
the x-ray system it develops for the Company. Digital x-ray systems, including
those currently on the market, reduce radiation exposure compared to
conventional x-ray systems and allow dentists to view x-ray images in real-time
without the time-consuming process of film development and eliminate the need to
use and dispose of chemicals required to develop conventional x-ray film. This
technology, if successfully developed for the Company by Suni, would provide an
improved image quality digital x-ray system at a price expected to be lower than
competitive systems. This technology also is designed to allow database storage
and recall of images for comparison purposes. The development of the technology
will be done by Suni and funded by the Company. No assurance can be given that
digital x-ray technology will be successfully developed, or if the technology is
developed, that the Company will be able to commercially exploit it.
Additionally, the Company believes that any products it may develop
incorporating the digital x-ray technology will require FDA notification prior
to marketing, and as a consequence, the timing of the domestic introduction of
such product is uncertain. The Company will determine whether or not to proceed
with the marketing of such product based upon the results of the development.
See "Cautionary Statements and Risk Factors -- Substantial Dependence on Third
Parties -- Suppliers."

In November 1996, the Company introduced its InTELInet Video Monitoring System
("InTELInet") which generally includes two TeliCam systems, a printer, a
video-cassette monitor, cabling and installation. InTELInet creates a
video-electronic information link between the different operatories of the
dental office. InTELInet is different from most other intra-office networking
systems known to the Company in that it enables simultaneous use of two or more
intraoral cameras, which allows dentists and their staffs to conduct more than
one patient examination at a time using two or more intraoral cameras
simultaneously. InTELInet is thus designed to be a cost-effective solution to
the problems generally associated with standard networking of various intraoral
cameras in multiple operatories within a single dental practice. The Company
emphasizes the savings to dental practices and the ease of use of the InTELInet
in its marketing campaigns. The InTELInet is being marketed by the Company only
in the United States due to the general absence of multiple operatory practices
outside of the United States. The InTELInet facilitates simple network expansion
and is only compatible with intraoral dental cameras marketed by the Company.
While there can be no assurance that digital x-ray technology will be developed,
the Company has designed the 


                                       12
<PAGE>   13

InTELInet system to be compatible with the digital x-ray technology the Company
is currently developing with Suni Imaging Microsystems, Inc.

On February 2, 1988 the Company formed "DMDS, Ltd." a wholly owned subsidiary
created under the laws of the United Kingdom. DMDS, Ltd. holds the assets
acquired from S.E.D. In addition, the Company currently plans to market certain
of its new products internationally through DMDS, Ltd.

On March 2, 1998, the Company entered into an agreement with accredited
investors and institutional purchasers for the private placement (the "Debt
Placement") of its 12% Senior Subordinated Notes due 1999 (the "Notes") and
450,000 warrants (the "1998 Warrants"). The Debt Placement was consummated on
March 19, 1998. The 1998 Warrants are (i) exercisable commencing on May 15,
1998, and for five years thereafter for the purchase of one share of Common
Stock per Warrant; and (ii) at an exercise price of $5.812 per share. The Notes
(i) bear interest payable semi-annually at a rate of 12% per annum; (ii) mature
on the first anniversary of the date of issuance; and (iii) may be repaid by the
Company prior to maturity at one hundred and two (102%) percent of the amount of
the unpaid principal plus interest due as of the date of repayment. As a result
of the warrant issuance, the Senior Subordinated Notes were discounted by
$1,620,225, which will be amortized over the term of the Notes. If the Notes are
unpaid at maturity, each Note holder has the option to convert the outstanding
principal and interest then due on such Note into Common Stock of the Company
(the "Conversion Shares") at a conversion price equal to eighty (80%) percent of
the average of the five lowest closing bid prices for the twenty consecutive
trading days prior to the date of conversion. The unpaid principal and interest
then due on the Notes is convertible into a maximum aggregate amount of 500,000
shares of Common Stock. Depending on the stock price at the time of conversion,
more than 500,000 shares of common stock may be required to permit conversion of
one hundred (100%) percent of the unpaid principal and interest then due on the
Notes into Common Stock. The Company has presented a proposal to its
stockholders at the annual meeting of stockholders to approve issuance of a
sufficient number of shares of Common Stock to permit conversion upon default of
one hundred (100%) percent of the unpaid principal and interest then due on all
of the outstanding Notes to Common Stock. This proposal was approved at the
meeting held on July 21, 1998.

Results of Operations

For the three-month periods ended June 30, 1998 and 1997, net sales totaled
$2,618,513 and $4,254,981, respectively. For the six-month periods ended June
30, 1998 and 1997, net sales totaled $4,729,044 and $8,183,263, respectively.
The Company incurred an operating loss of $1,645,334 for the quarter ended 
June 30, 1998 and an operating profit of $170,625 for the quarter ended 
June 30, 1997.

Net sales for the three-month period ended June 30, 1998 were $2,618,513
compared to $4,254,981 for the three-month period ended June 30, 1997, or a
decrease of approximately 38%. Net sales for the six-month period ended June 30,
1998 were $4,729,044 compared to $8,183,263 for the six-month period ended June
30, 1997, or a decrease of approximately 42%. Sales are comprised primarily of
sales of TeliCam Systems and related products. The decrease in sales was
primarily due to reduced TeliCam sales both domestically and internationally
resulting from weaker demand and increased competition as the market for
intraoral cameras matured. The Company expects the decline in TeliCam sales to
continue into the future. Partially offsetting the reduced TeliCam volume was
the introduction of the Apollo 95E, a tooth whitening and curing device, in
Europe. Sales of the Apollo 95E for the quarter ended June 30, 1998 were
$1,407,539. Although no assurance can be given that Apollo 95E sales will
ultimately offset the reduced TeliCam sales, the Company expects it will not
have the opportunity to fully offset the decline in TeliCam sales until it is
able to introduce the Apollo 95E in the United States. See - "Cautionary
Statements and Risk Factors - Importance of New Product Development to Growth".

Cost of sales for the three month period ended June 30, 1998 were $1,946,906 or
74% of sales as compared to $2,550,076 or 60% of sales for the three months
ended June 30, 1997. Cost of sales for the six month period ended June 30, 1998
were $3,496,995 or 74% of sales as compared to $5,027,720 or 61% of sales for
the six months ended June 30, 1997. Cost of sales increased as a percentage of
sales primarily due to the reduced sales volume effect on fixed overhead and a
change in sales mix to lower margin InTELInet sales. The Company expects margins
on the sale of the TeliCam's will be reduced in the next quarter as inventory of
the TeliCam II's will be sold at a discount in preparation for the introduction
of the TeliCam Elite.

Selling, general and administrative expenses totaled $2,134,639 and $1,496,707
for the three-months ended June 30, 1998 and 1997, respectively. Selling,
general and administrative expenses totaled $3,864,258 and $2,697,427 for the
six-months ended June 30, 1998 and 1997, respectively. The increase in expense
is primarily due to increased advertising, salary and wages, and 


                                       13
<PAGE>   14

legal and accounting expenses. These increases were primarily due to preparation
for the curing and whitening product introductions. These expenses are expected
to continue to increase as sales volume increases and as new products are
introduced. The Company expects that significant expenses will be incurred in
connection with introduction of the Apollo 95E.

Research and development expenses totaled $182,302 and $37,573 for the
three-month periods ended June 30, 1998 and 1997, respectively. Research and
development expenses totaled $324,689 and $73,334 for the six-month periods
ended June 30, 1998 and 1997, respectively. The increase is primarily the result
of continued expenditures on the development of the digital x-ray technology.
See "Cautionary Statements and Risk Factors - Importance of New Product
Development to Growth.", and "Cautionary Statements and Risk Factors - Expansion
through Undetermined Acquisitions and Joint-Ventures.". Increased expenditures
on research and development are expected to continue into future periods,
particularly in connection with the Company's digital x-ray product and in
connection with the investigation and/or development of additional product
lines.

Amortization of debt issuance cost totaled $75,000 and $28,370 for the three
month periods ended June 30, 1998 and 1997, respectively. Amortization of debt
issuance cost totaled $85,484 and $76,431 for the six- month periods ended June
30, 1998 and 1997, respectively. The amortization in the first six months of
1998 is a result of the costs associated with the $4.5 million Debt Placement on
March 19, 1998 and in the first six months of 1997, was a result of the Bridge
Notes issued in November 1996. This cost will continue into future periods.

Interest income totaled $64,057 and $48,965 for the three-month periods ended
June 30, 1998 and 1997, respectively. Interest income totaled $108,330 and
$48,965 for the six-month periods ended June 30, 1998 and 1997, respectively.
This is primarily the result of investing the net proceeds of the Private
Placement and Offering in a short-term management account through Comerica
Securities.

Interest expense totaled $549,497 and $42,427, respectively for the three month
periods ended June 30, 1998 and 1997. Interest expense totaled $633,290 and
$132,119, respectively for the six month periods ended June 30, 1998 and 1997.
Interest expense consists of interest paid on capital lease obligations,
interest accrued and amortization of debt discount on the $4.5 million Debt
Placement, interest accrued on the Comerica capital expenditure line, and notes
payable to related parties. The increase year-to-date is primarily due to the
amortization of debt discount and accrued interest on the $4.5 million Debt
Placement. This expense will also continue into future periods.



Capital Resources and Liquidity

For the six-month period ended June 30, 1998, the Company used net cash of
$4,147,103 in operations. Accounts receivable decreased by $343,819 to
$1,637,742 at June 30, 1998 primarily due to the reduction in camera sales and
to the slower sales months in the second quarter. See "Cautionary Statements and
Risk Factors - Fluctuations in Quarterly Results". Accounts payable and accrued
liabilities totaling $1,672,701 at June 30, 1998 decreased from $2,539,585 at
the prior year-end period primarily due to the reduction in purchases associated
with the TeliCam product line and the timing of payments. Inventory levels
increased $1,317,880 primarily due to the introduction of the Apollo 95E in
Europe.

Capital expenditures totaled $339,881 for the six month period ended June 30,
1998 and was primarily due to the new computer network system hardware and
software that is currently being implemented. Cash and cash equivalents on hand
at the end of the period were $3,914,316. The Debt Placement of the Company in
March 1998 provided approximately $4,200,000 in cash to the Company after
expenses.

On July 1, 1997, the Company finalized a credit agreement with Comerica Bank
("Comerica") extending up to a $2,000,000 line of credit to the Company, secured
by a first priority security interest in the Company's assets and by an
assignment of the Company's rights under the Boston Marketing Distribution
Agreement. The credit facility bears interest at the rate of prime plus .25% per
annum (8.75% at June 30, 1998). All borrowings under the facility are subject to
a formula based, generally, on accounts receivable and inventory. The Company
intends to use the credit facility, when needed, for working capital and general
corporate purposes. No amounts were outstanding at June 30, 1998.

On December 10, 1997, the Company finalized a second agreement with Comerica
Bank ("Comerica") extending up to a $500,000 line of credit to the Company for
capital expenditures, secured by a first priority interest in the Company's
assets. The 


                                       14
<PAGE>   15

credit facility bears interest at a rate of prime plus .5% per annum (9.0% at
June 30, 1998). The line expires on December 10, 1998. The principal balance
will amortize over a thirty-six--(36) month period. Borrowings are at 80% of the
capital expenditure. At June 30, 1998, $267,686 was outstanding.

At present, the expenditures for continued research and development for products
incorporating digital x-ray technology is the only significant future commitment
and will be financed by the remaining proceeds of the $4.5 million Debt
Placement. Based on its current operating plan, the Company anticipates that
unless a substantial portion of the Company's outstanding redeemable warrants
are exercised during the current fiscal year, in addition to the remaining
proceeds from the Debt Placement together with the credit facility, further
capital will be required during the next twelve months to satisfy the Company's
expected increased working capital and research and development requirements for
the new products. Exercise of the Company's redeemable warrants is unlikely
unless the market price of the Company's common stock is in excess of the
exercise of the redeemable warrants and, consequently, there can be no assurance
that a significant portion of the Company's outstanding redeemable warrants will
be exercised. The Company is currently exploring alternatives to fulfill its
financing requirements. No assurance can be given that additional financing will
be available when needed or that, if available, it will be on terms favorable to
the Company or its stockholders. If needed funds are not available, the Company
may be required to curtail its operations, which could have a material adverse
effect on the Company's business, operating results and financial condition.
There can be no assurance that the Company's working capital requirements during
this period will not exceed its available resources or that these funds will be
sufficient to meet the Company's longer-term cash requirements for operations.

Fluctuations in Quarterly Results

The Company's business is subject to certain quarterly influences. Net sales and
operating profit are generally higher in the fourth quarter due to the
purchasing patterns of dentists in the United States and are generally lower in
the first quarter due primarily to the effect upon demand of increased purchases
in the prior quarter. It is also expected that the Company's business will
experience lower sales in the summer months as a consequence of holiday
vacations and a lesser number of trade shows.

Quarterly results may be adversely affected in the future by a variety of other
factors, including the possible costs of obtaining capital, as well as the
release of new products and promotions taking place within the quarter. The
Company plans to continue to fund research and development and to increase
working capital requirements for the new products. To the extent that such
expenses precede or are not subsequently followed by increased revenues, the
Company's business, operating results and financial condition will be adversely
affected.

Year 2000 Issue

Many computer systems experience problems handling dates beyond the year 1999.
Therefore, some computer hardware and software will need to be modified prior to
the year 2000 in order to remain functional. The Company is assessing both the
internal readiness of its computer systems and compliance of its computer
products and software sold to customers for handling the year 2000. The Company
expects to implement successfully the systems programming changes necessary to
address year 2000 issues, and does not believe that the cost of such actions
will have a material effect on the Company's results of operations or financial
condition. There can be no assurance, however, that there will not be a delay
in, or increased costs associated with the implementation of such changes, and
the inability to implement such changes could have an adverse effect on future
results of operations.


CAUTIONARY STATEMENTS AND RISK FACTORS


Several of the matters discussed in this document contain forward looking
statements that involve risks and uncertainties. Factors associated with the
forward looking statements, which could cause actual results to differ
materially from those projected or forecast in the statements, appear below. In
addition to other information contained in this document, readers should
carefully consider the following cautionary statements and risks factors:

   Limited Operating History; History of Losses and Accumulated Deficit. While
the Company has been in existence since 1981, its operations between 1988 and
its acquisition of DMD and BDI in March 1996, were limited to the exploration of
acquisition opportunities. Dental/Medical Diagnostic Systems, the division of
the Company which designs and markets the Company's 


                                       15
<PAGE>   16

TeliCam Systems, and BDI, a subsidiary of the Company, have only been in
operation since October 1995. For the period from inception (October 23, 1995)
to March 2, 1996, the Company incurred a net loss of $1,625,213, and for the
ten-month period ended December 31, 1996, the Company had net income of
$137,151. For the twelve months ended December 31, 1997 the Company had a net
loss after extraordinary item of $2,044,729, and for the six months ended June
30, 1998 the Company had a net loss of $3,567,342. At June 30, 1998, the
Company's accumulated deficit was $7,100,132. The ability of the Company to
obtain and sustain profitability will depend, in part, upon the successful
marketing of existing products and the successful and timely introduction of new
products. There can be no assurance that the Company will be able to generate
and sustain net sales or profitability in the future.

   Dependence Upon a Single Product. The TeliCam Systems have been the Company's
primary product and, together with related products such as the InTELInet
system, accounted for a substantial portion of the Company's revenue. See "--
Importance of New Product Development to Growth." The Company believes that the
market for intraoral cameras, such as the TeliCam systems, is a market that has
matured. TeliCam Systems sales have recently been below levels of prior
comparable periods, a trend which the Company expects to continue. If the
Company is unable to successfully develop and introduce additional products and
product lines, or obtain 510(k) notification for domestic introduction of its
Apollo 95E now being sold internationally, it is likely that the Company's
business operations would be substantially and adversely impacted.

   Importance of New Product Development to Growth. The Company's ability to
develop and successfully introduce new products, particularly obtaining 510(k)
notification for the tooth whitening and curing device, the Apollo 95E, a line
of tooth whitening chemicals and composites, and the digital x-ray technology
under development for the Company by Suni, will be a significant factor in the
Company's ability to grow and remain competitive. See "Cautionary Statements and
Risk Factors -- Substantial Dependence on Third Parties -- Suppliers."
Development of new product lines is risk intensive as evidenced by ILT's recent
announcement that it will be unable to perform its obligations under its
agreement with the Company to develop and supply the Apollo 9500 to the Company.
New product development often requires long-term forecasting of market trends,
the development and implementation of new designs, compliance with extensive
governmental regulatory requirements and a substantial capital commitment. There
are a number of manufacturing and design risks inherent in engineering high cost
custom built prototypes upon which development and contracting decisions are
often made, into commercial products able to be manufactured in large quantities
at acceptable cost. Also, the medical and dental device industry is
characterized by rapid technological change. As technological changes occur in
the marketplace, the Company may have to modify its products in order to keep
pace with these changes and developments. The introduction of products embodying
new technologies, or the emergence of new industry standards, may render
existing products, or products under development, obsolete or unmarketable. Any
failure by the Company to anticipate or respond in a cost-effective and timely
manner to government requirements, market trends or customer requirements, or
any significant delays in product development or introduction, could have a
material adverse effect on the Company's business, operating results and
financial condition.

   Need For Additional Financing. Based on its current operating plan, the
Company anticipates that unless a substantial portion of the outstanding
warrants of the Company are exercised by the respective holders thereof, in
addition to the credit facility and the remaining proceeds of the Debt
Placement, further capital will be required during the next twelve months to
satisfy the Company's expected increased working capital and research and
development requirements for its planned new products. The Company is currently
exploring alternatives to fulfill these requirements. No assurance can be given
that additional financing will be available when needed or that, if available,
it will be on terms favorable to the Company or its stockholders. If needed
funds are not available, the Company may be required to curtail its operations,
which could have a material adverse effect on the Company's business, operating
results and financial condition. If additional funds are raised through the
issuance of equity securities, additional dilution to stockholders may occur. In
addition, if sufficient funds to repay the Notes are not available, the Notes
may be converted to shares of Common Stock and additional dilution to
stockholders may occur.

   Expansion through Undetermined Acquisitions and Joint Ventures. The Company
intends to expand its product lines and domestic and international markets, in
part, through acquisitions. The Company's ability to expand successfully through
acquisitions will depend upon the availability of suitable acquisition
candidates at prices acceptable to the Company, the Company's ability to
consummate such transactions and the availability of financing on terms
acceptable to the Company. There can be no assurance that the Company will be
successful in completing acquisitions. Such transactions involve numerous risks,
including possible adverse short-term effects on the Company's operating results
or the market price of the Common Stock. These acquisitions and joint ventures
may not be subject to approval or review by the Company's stockholders. The
Company does not expect that it will obtain an appraisal by any independent
appraisers with respect to any such acquisition. Certain of the Company's future
acquisitions may also give rise to an obligation by the Company to make
contingent payments or to satisfy 


                                       16
<PAGE>   17

certain repurchase obligations, which payments could have an adverse financial
effect on the Company. In addition, integrating acquired businesses may result
in a loss of customers or product lines of the acquired businesses and also
requires significant management attention and may place significant demands on
the Company's operations, information systems and financial resources. The
failure effectively to integrate acquired businesses with the Company's
operations could adversely affect the Company. In addition, the Company competes
for acquisition opportunities with companies which have significantly greater
financial and management resources than those of the Company. There can be no
assurance that suitable acquisition opportunities will be identified, that any
such transactions can be consummated, or that, if acquired, such new businesses
can be integrated successfully and profitably into the Company's operations.
Moreover, there can be no assurance that the Company's historic rate of growth
will continue, that the Company will continue to successfully expand, or that
growth or expansion will result in profitability.

The Company also intends to expand its product lines and domestic and
international markets through joint ventures. The Company's ability to expand
successfully through joint ventures will depend upon the availability of
suitable joint venture candidates whose terms are acceptable to the Company, the
Company's ability to consummate such transactions and the availability of
financing on terms acceptable to the Company. There can be no assurance that the
Company will be successful in completing joint ventures. Such transactions
involve numerous risks, including possible adverse short-term effects on the
Company's operating results or the market price of the Common Stock. The failure
effectively to integrate joint ventures with the Company's operations could
adversely affect the Company. In addition, the Company competes for expansion
opportunities with companies which have significantly greater financial and
management resources than those of the Company. There can be no assurance that
suitable investment opportunities will be identified, that any such transactions
can be consummated, or that such new businesses can be integrated successfully
and profitably into the Company's operations. Moreover, there can be no
assurance that the Company's historic rate of growth will continue, that the
Company will continue to successfully expand, or that growth or expansion will
result in profitability.

Substantial Dependence on Third Parties: The Company substantially depends upon
third parties for several critical elements of its business including the
development and licensing for distribution of its products.

   Suppliers. With the exception of the TeliCam System's CCD processor unit, the
Company believes that there are multiple sources from which it may purchase the
components of the TeliCam System. The Company anticipates that it will obtain
certain of the components of the TeliCam System from a single source or a
limited number of sources of supply. Although the Company believes it will be
able to negotiate satisfactory supply arrangements and relationships, the
failure to do so may have a material adverse effect on the Company. Furthermore,
there can be no assurance that suppliers will dedicate sufficient production
capacity to satisfy the Company's requirements within scheduled delivery times
or at all. Failure or delay by the Company's suppliers in fulfilling its
anticipated needs may adversely affect the Company's ability to market the
TeliCam System. Pursuant to the Boston Marketing Distribution Agreement, the
Company has the exclusive right to market Teli Units to the dental market.
Boston Marketing is a licensed distributor of the Teli Units under a separate
agreement with their manufacturer. The agreement between Boston Marketing and
the Teli Units manufacturer obligates Boston Marketing to meet minimum purchase
obligations. If Boston Marketing fails to meet these obligations, Boston
Marketing will be terminated as a licensed distributor. In the event of such
termination, the Company, as a sublicensee subdistributor of Boston Marketing,
may lose its right to purchase the Teli Units. Moreover, in the event the
Company is unable to meet its minimum annual purchase obligations under the
Boston Marketing Distribution Agreement, and, as a consequence, such agreement
terminates, the Company may be required to find an alternative source for the
primary component of its TeliCam System. The Company believes that, in the event
the Company loses its right to sell the Teli Units, replacement components could
be developed by and obtained from third parties, but that this may take more
than six months. The potential delay associated with locating an alternative
source of supply would have a significant adverse effect on the Company's
operating results and financial condition. In addition, there is no guarantee
that an intraoral dental camera system utilizing the replacement components will
be accepted by the dental marketplace. The Company has an oral agreement with
S.E.D. to manufacture its Apollo 95E product for sale internationally. Dr.
Duret, president of S.E.D. will oversee manufacturing of the Apollo 95E for the
Company, and will render consulting services for the Company. If S.E.D. were
unable to meet the Company's requirements, the Company would have to obtain an
alternative manufacturing arrangement. The Company believes that such
manufacturing capability could be developed by the Company or obtained from
third parties, but that developing or obtaining alternative capacities may take
up to four months. The potential delay associated with either developing or
locating an alternative source of supply could have a significant adverse effect
on the Company's operating results and financial condition.


                                       17
<PAGE>   18

The Company will be dependent upon third party developers and suppliers for the
development and manufacture of tooth whitening chemicals and composites for sale
with the Apollo 95E. Although tooth whitening chemicals and composites usable
with the Apollo 95E are commercially available, failure by the Company to
develop and market a proprietary line of tooth whitening and composite chemicals
would have an adverse effect on the companies earnings and revenues because of
higher cost of goods associated with and lesser functionality of commercially
available products.

   Suni. Under the Company's licensing and development arrangements with Suni
for the development of digital x-ray technology for the dental market, the
Company has obtained exclusive marketing rights to products incorporating
certain digital x-ray technology developed by Suni. The Company has paid
significant advances to, and is dependent upon Suni to successfully develop the
digital x-ray technology and to commercialize the digital x-ray technology.
There can be no assurance that Suni will be successful in this endeavor. If Suni
should not develop a digital x-ray product acceptable to the Company or the
marketplace, this would have a material adverse effect on the Company's
operating results and financial condition. The agreement with Suni provides that
the Company is obligated to make minimum royalty payments if products
incorporating the developed technology are introduced to the market in order to
maintain exclusivity. There can be no assurance that the Company will be able to
meet the royalty payments required to maintain exclusivity. Suni would then be
able to license the developed technology to the Company's competitors, or grant
an exclusive license to a competitor, which could have a material adverse effect
on the Company's operating results and financial condition.

   Fluctuations in Quarterly Results. The Company's business is subject to
certain quarterly influences. Management's prior experience in the industry
would indicate that net sales and operating profits are generally higher in the
fourth quarter due to the purchasing patterns of dentists and are generally
lower in the first quarter due primarily to increased purchases in the prior
quarter and during the summer months due to a reduced volume of trade shows and
increased unavailability of dentists due to summer vacations. The Company plans
to increase expenses to fund greater levels of research and development and to
fund investments in joint ventures and acquisitions. To the extent that such
expenses precede or are not subsequently followed by increased revenues, the
Company's business, quarterly operating results and financial condition will be
adversely affected. Quarterly results may also be adversely affected by a
variety of other factors, including the timing of acquisitions and their related
costs, as well as the release of new products and promotions taking place within
the quarter. Other factors that may influence the Company's quarterly operating
results include the timing of introduction or enhancement of products by the
Company or its competitors, market acceptance of the TeliCam Elite, the
InTELInet System, the Apollo 95E and other new products, development and
promotional expenses relating to the introduction of new products or
enhancements of existing products, reviews in the industry press concerning the
products of the Company or its competitors, changes or anticipated changes in
pricing by the Company or its competitors, mix of distribution channels through
which products are sold, mix of products sold, product returns, the timing of
orders from major distributors, order cancellations, delays in shipment and
general economic conditions. Due to all of the foregoing factors, it is also
likely that in some future periods the Company's operating results may be below
the expectations of analysts and investors. In such event, the price of the
Company's Common Stock would likely be materially adversely affected.

   Extensive Government Regulation. The Company's products and its manufacturing
practices are subject to regulation by the United States Food and Drug
Administration ("FDA") pursuant to the Federal Food, Drug and Cosmetic Act ("FDC
Act"), and by other state and foreign regulatory agencies. Under the FDC Act,
medical and dental devices, including those under development by the Company
must receive FDA clearance or notification before they may be sold, or be
exempted from the need to obtain such clearance or notification. FDA regulations
also require the Company to adhere to certain "Good Manufacturing Practices"
("GMP") regulations, which include validation testing, quality control and
documentation procedures. The Company's compliance with applicable regulatory
requirements is subject to periodic inspections by the FDA.

The Company has filed for 510(k) notification for its Apollo 95E and will need
to do the same for any new products that are developed in the future using
digital x-ray technology. The process of obtaining required regulatory
clearances or notifications can be time-consuming and expensive, and compliance
with the FDA's GMP regulations and other regulatory requirements can be
burdensome. Moreover, there can be no assurance that the required regulatory
notifications will be obtained, and those obtained may include significant
limitations on the uses of the product in question. In addition, changes in
existing regulations or the adoption of new regulations could make regulatory
compliance by the Company more difficult in the future. Although the Company
believes that its products and procedures are currently in material compliance
with all relevant FDA requirements, the failure to obtain the required
regulatory clearances or to comply with applicable regulations could result in
fines, delays or suspensions of clearances, seizures or recalls of products,
operating restrictions and criminal prosecutions, and would have a material
adverse effect on the Company.


                                       18
<PAGE>   19

   Competition. The manufacture and distribution of medical and dental devices
is intensely competitive. The Company competes with numerous other companies,
including several major manufacturers and distributors. With respect to the
intraoral camera market, the Company has at least twelve major competitors. The
Apollo 95E presently has two major competitors. Some of the Company's
competitors have greater financial and other resources than the Company.
Consequently, such entities may begin to develop, manufacture, market and
distribute systems which are substantially similar or superior to the Company's
products.

   Rapid Expansion of the Company's Business. From inception (October 23, 1995)
through June 30, 1998, the Company has experienced rapid and substantial growth
in revenues and geographic scope of operations. Any future growth may place a
significant strain on management and on the Company's financial resources and
information processing systems. The failure to recruit additional staff and key
personnel, to have sufficient financial resources, to maintain or upgrade these
financial reporting systems, or to respond effectively to difficulties
encountered during expansion could have a material adverse effect on the
Company's business, operating results and financial condition.

   Reliance on International Sales and Distributors and General Risks of
International Operations. For the six-month period ended June 30, 1998,
international sales have accounted for approximately 33% of the Company's net
sales, and the Company expects that international sales may increase as a
percentage of sales in the future. Consequently, the Company is subject to the
risks of conducting business internationally, including unexpected changes in,
or impositions of, legislative or regulatory requirements; fluctuations in the
US dollar which could materially adversely affect US dollar revenues; tariffs
and other barriers and restrictions; potentially adverse taxes; and the burdens
of complying with a variety of international laws and communications standards.
The Company's international sales involve potentially longer payment cycles and
the Company may experience greater difficulty collecting accounts receivable.
The Company currently depends on third party distributors for substantially all
of its international sales. At June 30, 1998, the Company's international
receivables accounted for 87% of the Company's accounts receivable, and
international sales were approximately $1,547,707 or 33%, of the Company's total
sales for the six-month period ended June 30, 1998. Certain of the Company's
third party distributors may also act as resellers for competitors of the
Company and could devote greater effort and resources to marketing competitive
products. The loss of, or other significant reduction in sales to, certain of
these third party distributors could have a material adverse effect on the
Company's business and results of operations. The Company is also subject to
general geopolitical risks, such as political and economic instability and
changes in diplomatic and trade relationships, in connection with its
international operations. There can be no assurance that these risks of
conducting business internationally will not have a material adverse effect on
the Company's business. Further, any failure by the Company to predict or plan
for changes in the international arena could have a material adverse effect on
the Company's business, operating results and financial condition.

   Dependence on Key Personnel. The Company's future performance will depend
significantly upon its Chairman of the Board and Chief Executive Officer, Robert
H. Gurevitch, and upon certain other key employees of the Company. The loss of
service of one or more of these persons could have a material adverse effect on
the Company's business and operations. The Company has entered into Employment
Agreements with Robert H. Gurevitch and Dewey Perrigo, the Company's Vice
President of Sales, pursuant to which they each have agreed to render services
to the Company until October 1, 1999. The Company has obtained "key person" life
insurance on Mr. Gurevitch in the amount of $2,000,000, of which the Company is
the sole beneficiary, but there can be no assurance that the proceeds of such
insurance will be sufficient to offset the loss to the Company in the event of
his death. The Company does not maintain any insurance on the lives of its other
senior management. In addition, the Company's success will be dependent upon its
ability to recruit and retain qualified personnel. Any failure by the Company to
retain and attract key personnel could have a material adverse effect on the
Company's business, operating results, and financial condition.

   Limited Proprietary Protection. The Company's success and ability to compete
is dependent in part upon its proprietary technology. The Company's proprietary
technology is not protected by any patents, with the exception of the Apollo 95E
which has a patent pending. Consequently, the Company relies primarily on
trademark, trade secret and copyright laws to protect its technology. Also, the
Company has implemented a policy that most senior and technical employees and
third-party developers sign nondisclosure agreements. However, there can be no
assurance that such precautions will provide meaningful protection from
competition or that competitors will not be able to develop similar or superior
technology independently. Also, the Company has no license agreements with the
end users of its products, so it may be possible for unauthorized third parties
to copy the Company's products or to reverse engineer or otherwise obtain and
use information that the Company regards as proprietary. If litigation is
necessary in the future, to enforce the Company's intellectual property rights,
to protect the Company's trade secrets or to determine the validity and scope of
the proprietary rights of others, such litigation could result in substantial
costs and diversion of resources and could have a material adverse effect on the
Company's business, operating results and 


                                       19
<PAGE>   20

financial condition. Ultimately, the Company may be unable, for financial or
other reasons, to enforce its rights under intellectual property laws. In
addition, the laws of certain countries in which the Company's products are or
may be distributed may not protect the Company's products and intellectual
property rights to the same extent as the laws of the United States.

The Company believes that its products do not infringe upon any valid existing
proprietary rights of third parties. Although the Company has received no
communication from third parties alleging the infringement of proprietary rights
of such parties, there can be no assurance that third parties will not assert
infringement claims in the future. Any such third party claims, whether or not
meritorious, could result in costly litigation or require the Company to enter
into royalty or licensing agreements. There can be no assurance that the Company
would prevail in any such litigation or that any such licenses would be
available on acceptable terms, if at all. If the Company were found to have
infringed upon the proprietary rights of third parties, it could be required to
pay damages, cease sales of the infringing products and redesign or discontinue
such products, any of which alternatives, individually or collectively could
have a material adverse effect on the Company's business, operating results and
financial condition.

   Conflict of Interests. Robert Gurevitch, Chairman of the Company, has loaned
money to the Company ("Loan Obligations") and has guaranteed the performance by
the Company under its leases for its Irvine (Technology Drive) and Westlake,
California premises. The Company believes that all of these transactions were on
terms no less favorable than were available from unaffiliated third parties. The
Company intends to attempt to relieve Mr. Gurevitch from his obligations under
each of these guarantees and it is possible that, in order to achieve the
release of Mr. Gurevitch from these guarantees, the Company will be required to
post collateral or provide other concessions to the recipients of the
guarantees. The Company has, in the past, entered into transactions with
affiliates and there can be no assurance that the Company will not enter into
transactions with affiliated parties in the future.

   Limitation of Liability and Indemnification. The Company's Amended and
Restated Certificate of Incorporation limits, to the maximum extent permitted by
the Delaware General Corporation Law ("Delaware Law"), the personal liability of
directors for monetary damages for breach of their fiduciary duties as a
director, and provides that the Company shall indemnify its officers and
directors and may indemnify its employees and other agents to the fullest extent
permitted by law. The Company has entered into indemnification agreements with
its directors and executive officers which may require the Company, among other
things, to indemnify such directors or executive officers against liabilities
that arise by reason of their status or service as directors or officers (other
than liabilities arising from willful misconduct of a culpable nature) and to
advance their expenses incurred as a result of any proceeding against them as to
which they could be indemnified. The Company has purchased director's and
officer's liability insurance in the amount of $5.0 million. Section 145 of the
Delaware Law provides that a corporation may indemnify a director, officer,
employee or agent made, or threatened to be, a party to an action by reason of
the fact that he was a director, officer, employee or agent of the corporation
or was serving at the request of the corporation against expenses actually and
reasonably incurred in connection with such action if he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the best interests
of the corporation, and, with respect to any criminal action or proceeding, if
he had no reasonable cause to believe his conduct was unlawful. Delaware Law
does not permit a corporation to eliminate a director's duty of care, and the
provisions of the Company's Amended and Restated Certificate of Incorporation
have no effect on the availability of equitable remedies, such as injunction or
rescission, for a director's breach of the duty of care.

   Anti-Takeover Provisions. The Company has an authorized class of 1,000,000
shares of preferred stock, which may be issued by the Board of Directors on such
terms, and with such rights, preferences and designations as the Board of
Directors may determine. Issuance of such preferred stock, depending upon the
rights, preferences and designations thereof, may have the effect of delaying,
deterring or preventing a change in control of the Company. In addition, certain
"anti-takeover" provisions of the Delaware Law, among other things, restrict the
ability of stockholders to effect a merger or business combination or obtain
control of the Company, and may be considered disadvantageous by a stockholder.

   Product Liability. Although the Company has not experienced any product
liability claims to date, the sale and support of products by the Company may
entail the risk of such claims, and there can be no assurance that the Company
will not be subject to such claims in the future. A successful product liability
claim or claim arising as a result of use of the Company's products brought
against the Company, or negative publicity attendant to any such claim, could
have a material adverse effect upon the Company's business, operating results
and financial condition. The Company maintains product liability insurance with
coverage limits of $1,000,000 per occurrence and $1,000,000 per year. While the
Company believes that it maintains adequate insurance coverage, there can be no
assurance that the amount of insurance will be adequate to satisfy claims made
against the Company in the future, or that the Company will be able to obtain
insurance in the future at satisfactory rates or in adequate amounts.

Item 2. Changes in Securities and Use of Proceeds.


RECENT SALES

On March 2, 1998, the Company entered into an agreement with accredited
investors and institutional purchasers for the private placement (the "Debt
Placement") of its 12% Senior Subordinated Notes due 1999 (the "Notes") and
450,000 warrants (the "Warrants"). The Debt Placement was consummated on March
19, 1998. The Debt Placement was exempt from Registration under Section 4(2) of
the Act and Rule 506 of Regulation D promulgated under the Act. The Warrants are
(i) exercisable commencing on May 15, 1998, and for five years thereafter for
the purchase of one share of Common Stock per Warrant (the "Warrant Shares");
and (ii) at an exercise price of $5.812 per share. The Company has filed a
registration statement with respect to the Warrant Shares. The Notes (i) bear
interest at a rate of 12% per annum payable semi-annually; (ii) mature on the
first anniversary of the date of issuance; and (iii) may be repaid by the
Company prior to maturity at one hundred and two (102%) percent of the amount of
the unpaid principal plus the interest due as of the date of repayment. If the
Notes are unpaid at maturity, each Note holder has the option to convert the
outstanding principal and interest then due on such Note into Common Stock of
the Company (the "Conversion Shares") at a conversion price equal to eighty
(80%) percent of the average of the five lowest closing bid prices for the
twenty consecutive trading days prior to the date of conversion. The unpaid
principal and interest then due on the Notes is convertible into a maximum
aggregate amount of 500,000 shares of Common Stock. Depending on the stock price
at the time of conversion, more than 500,000 shares of Common Stock may be
required to permit conversion of one hundred (100%) percent of the unpaid
principal and interest then due on the Notes into Common Stock. The Company
presented a proposal to its stockholders at the annual meeting of stockholder's,
held July 21,1998, to approve issuance of a sufficient number of shares of
Common Stock to permit conversion upon default of one hundred (100%) percent of
the unpaid principal and interest then due on all of the outstanding Notes to
Common Stock. The proposal was approved at that meeting. The Company has to file
a registration statement with respect to any Conversion Shares within 45 days of
the date the Notes mature, if the Notes are then unpaid. The Company intends to
use the proceeds of the Debt Placement of $4.2 million, net of commissions and
costs, to launch its Apollo 95E product, for product development and for other
working capital purposes.
