               Integrated Surgical Systems, Inc. and Subsidiaries
        Notes to Condensed Consolidated Financial Statements (unaudited)
                               September 30, 2004

1. Basis of Presentation

The condensed consolidated financial statements have been prepared by Integrated
Surgical Systems, Inc. (the "Company") pursuant to the rules and regulations of
the Securities and Exchange Commission ("SEC"). Certain information and footnote
disclosures normally included in annual financial statements prepared in
accordance with accounting principles generally accepted in the United States of
America have been condensed or omitted as permitted by such rules and
regulations. While the interim financial information contained in this filing is
unaudited, such financial statements reflect all adjustments, consisting only of
normal recurring adjustments, which the Company considers necessary for a fair
presentation. The results for interim periods are not necessarily indicative of
the results to be expected for the entire fiscal year. These financial
statements should be read in conjunction with the consolidated financial
statements and notes thereto included in the Company's Annual Report on Form
10-KSB for the fiscal period ended December 31, 2003.

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts and related
disclosures. Actual results could differ from those estimates.

2. Results of Operations and Management's Plan

The accompanying condensed consolidated financial statements have been prepared
on a going concern basis, which contemplates the realization of assets and the
satisfaction of liabilities in the normal course of business. As shown in the
accompanying condensed consolidated financial statements for the nine-month
period ended September 30, 2004, the Company incurred a net loss for such
nine-month period of $1,045,133 and had an accumulated deficit as of September
30, 2004 of $68,776,342. For the year ended December 31, 2003, the Company
incurred a net loss of $3,250,219 and had an accumulated deficit at December 31,
2003 of $67,731,209. The report of independent auditors on the Company's
December 31, 2003 consolidated financial statements includes an explanatory
paragraph indicating there is substantial doubt about the Company's ability to
continue as a going concern. The Company believes that it has a plan to address
these issues and enable the Company to continue operating through September 30,
2005. This plan includes obtaining additional equity or debt financing,
increasing product sales in existing markets, increasing sales of system
upgrades, and further reductions in operating expenses as necessary (see notes 5
and 11). Although the Company believes that the plan will be realized, there is
no assurance that these events will occur. In the event that the Company is
unsuccessful in realizing the benefits of such plan, it is possible that the
Company will cease operations and/or seek bankruptcy protection. The September
30, 2004 condensed consolidated financial statements do not include any
adjustments to reflect the uncertainties related to the recoverability and
classification of assets or the amounts and classification of liabilities that
may result from an inability of the Company to continue as a going concern.

3. Inventories

At September 30, 2004, the components of inventories were:

Raw materials                                                           $123,031
Work-in-process                                                          218,731
Finished goods                                                           137,465
Deferred product development contract costs                              129,364

                                                                        $608,591
                                                                        ========

4. Warranty and Service Contracts

The Company offers a one-year warranty for parts and labor on all ROBODOC(R)
systems. These warranties generally commence upon the completion of training and
installation. In most cases, the Company's customers purchase a service
contract, which includes extended warranty coverage (parts and labor),
unspecified product maintenance updates, customer support services and various
consumables required during surgical procedures. Customers not covered by
warranties or service contracts are billed on a time and materials basis for
service, and on a per unit basis for products. At September 30, 2004, the
Company had no recorded warranty liability as all systems within the one-year
warranty period were covered by service contracts. Revenue related to
maintenance and service contracts is recognized ratably over the duration of the
contract.

5. Securities Purchase Agreement

To obtain funding for the Company's ongoing operations, the Company entered into
a securities purchase agreement (the "Agreement") with an accredited investor on
June 15, 2004 with respect to the sale by the Company for aggregate
consideration of $150,000 of (i) a convertible debenture in the principal amount
of $150,000 and (ii) warrants to purchase 1,500,000 shares of Company common
stock. The Agreement contemplates the sale of additional convertible debentures
and warrants upon the occurrence of specific events. The Company is obligated to
register under the Securities Act for resale by the investor the common stock
underlying the debenture and warrants issued pursuant to the Agreement.

In connection with the sale of the original $150,000 convertible debenture and
1.5 million warrants the investor provided the Company with funds as follows:

     o    $100,000 was disbursed to the Company on June 15, 2004;

     o    $50,000 was disbursed to the Company on October 19, 2004; and

     o    $50,000 has been retained by the investor for disbursement to various
          professionals in payment for services to be provided to the Company.

The convertible debenture bears interest at 6 3/4%, matures two years from the
date of issuance, and is convertible into Company common stock at the investor's
option. The convertible debenture is convertible into the number of shares of
Company common stock equal to the principal amount of the debenture being
converted multiplied by 11, less the product of the conversion factor multiplied
by ten times the dollar principal amount of the debenture being converted. The
conversion factor for the convertible debenture is the lesser of (i) $0.25 or
(ii) eighty percent of the average of the five lowest volume weighted average
prices during the twenty (20) trading days prior to the conversion. Accordingly,
there is no limit on the number of shares into which the debenture may be
converted. In addition, the investor is obligated to proportionately exercise,
concurrently with the submission of a conversion notice by the selling
stockholder, the warrants. The warrants are at an exercise price of $1.00 per
share.

The investor has contractually agreed to restrict its ability to convert
or exercise its warrants and receive shares of Company common stock such that
the number of shares of common stock held by it and its affiliates after such
conversion and exercise does not exceed 4.9% of the then issued and outstanding
shares of Company common stock.

The issuance of more than 51.5 million shares of common stock upon conversion of
the convertible debenture and exercise of the warrants issued pursuant to the
Agreement would require the Company to issue shares of common stock in excess of
the Company's currently authorized shares of its common stock. The Company
intends to seek stockholder approval to amend the Company's certificate of
incorporation to increase the Company's authorized common stock from 100,000,000
to 300,000,000 shares. Such solicitation will be made pursuant to a proxy
statement conforming to the rules and regulations of the Securities and Exchange
Commission. This Quarterly Report on Form 10-QSB should not be considered, in
any manner, a solicitation for voting in favor of such an increase in the
Company's authorized common stock.


                                       8
<PAGE>


The issuance of the convertible debenture and warrants to the investor is
contingent upon stockholder approval of the increase in the Company's authorized
common stock. If such approval is not received, the Agreement will terminate and
the Company will be obligated to repay the proceeds received to date and other
funds disbursed by the investor to professionals in payment of services rendered
on behalf of the Company. As a result, the Company recorded such proceeds in
other current liabilities.

6. Stockholders' Equity

During the nine-month period ended September 30, 2004, 61,587 shares of common
stock were issued as a result of employees exercising stock options at exercise
prices ranging from $0.025 to $0.06 per share. The Company also issued 40,000
and 90,000 shares of its common stock, at $ 0.095 and $0.06 per share,
respectively, as payment for services rendered.

7. Stock-Based Compensation

The Company uses the intrinsic value method in accounting for its employee stock
options in accordance with Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees." Under the intrinsic value method,
when the exercise price of employee stock option equals or exceeds the market
price of the underlying stock on the date of grant, no compensation expense is
recognized. Stock option awards which are granted at less than fair market value
result in the recognition of deferred compensation. Deferred compensation is
shown as a reduction of stockholders' equity and is amortized to operating
expenses over the vesting period of the stock award. The Company had no deferred
compensation at September 30, 2004.

Statement of Financial Accounting Standards No. 148, "Accounting for Stock-Based
Compensation-Transition and Disclosure of an Amendment of SFAS No. 123" and
Statement of Financial Accounting Standards No. 123 ("SFAS No. 123"),
"Accounting for Stock-Based Compensation," require the disclosure of certain
information as if the Company had adopted the fair value provisions of SFAS No.
123. The table below illustrates the effect on net loss and net loss per share
had the Company adopted the fair value provisions of SFAS No. 123 using the
following assumptions: risk-free interest rates of 3.4% for the three-months
and nine-month periods ended September 30, 2004 and 3.0% for the three-months
and nine-month periods ended September 30, 2003; volatility factors of the
expected market price of the common stock of 1.006 for the three-months and
nine-month periods ended September 30, 2004 and 1.004 for the three-months and
nine-month periods ended September 30, 2003 and an expected life of the option
of 4 years.

8. Net Loss Per Share

Basic net loss per share is computed by dividing the net loss available to
common stockholders for the period by the weighted average number of common
shares outstanding during the period. Diluted net loss per share is computed by
dividing the net loss for the period by the weighted average number of common
and potential common shares outstanding during the period if their effect is
dilutive. Potential common shares are comprised of shares issuable upon exercise
or conversion of outstanding employee stock options, warrants and convertible
preferred stock. The potential common shares issuable under stock options,
warrants and preferred stock to purchase common shares have been excluded for
the three and nine-month periods ending September 30, 2004 and 2003 from the
diluted calculation because the effect of such shares would have been
anti-dilutive.

At September 30, 2004, the Company had outstanding options to purchase an
aggregate of 2,332,734 shares of common stock (with exercise prices ranging from
$0.025 to $8.50 per share), warrants to purchase an aggregate 2,606,479 shares
of common stock (with exercise prices from $0.01 to $0.0625 per share), and of
Series G convertible preferred stock convertible into 3,150,333 shares of common
stock. The exercise price and the ultimate number of shares of common stock
issuable upon exercise of outstanding options and warrants and conversion of the
Series G convertible preferred stock are subject to adjustments based upon the
occurrence of certain future events.

10. Contingencies

The Company is subject to legal proceedings and claims that arise in the normal
course of business. The Company cannot assure that it would prevail in such
matters nor can it assure that the Company would have sufficient funds available
to satisfy any adverse judgement. Due to the inherent uncertainties of
litigation, were there any such matters, the Company may not be in the position
at any specific time to accurately predict a litigation's ultimate outcome. As
of September 30, 2004, there were no current proceedings or litigation involving
the Company that the Company believes, if judgement were rendered against the
Company, would have a material adverse impact on its financial position, results
of operations or cash flows

11. Subsequent Events

On December 14, 2004 the Company entered into a $2.5 million agreement with
Fujifilm Medical Systems, USA ("Fuji") under which Fuji will license the
Company's orthopedic surgical planning technology for its use solely in the
Picture Archiving and Communications Systems ("PACS") market. Under the terms of
the license agreement the Company received $0.5 million in conjunction with the


                                       10

signing of the agreement. Additional milestone payments totaling $2.0 million
will be paid to the Company over a two year period, assuming all such milestones
are met.

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

Overview

The Company designs, manufactures, sells and services image-directed,
computer-controlled robotic software and hardware products for use in orthopedic
and neurosurgical procedures.

In 1997, the Company acquired a 100% interest in a French company, Innovative
Medical Machines International. S. A. ("ISS-SA"), involved in the manufacturing
and servicing of neurosurgical products. In the fourth quarter of 2003, the
Company recorded a loss of $1,516,519 in connection with the liquidation of the
Company's investment in ISS-SA and closure of the Company's European operation.

The Company's revenue consists of product revenue, product development revenue,
parts and consumables and service revenue.

Product revenue consists of the Company's principal orthopaedic product, the
ROBODOC(R) Surgical Assistant System ("ROBODOC"), which integrates the
ORTHODOC(R) Presurgical Planner ("ORTHODOC") with a computer-controlled robot
for use in joint replacement surgeries. Also included in product revenue for the
first and second quarters of 2003 are sales of the NeuroMate(TM) System
("NeuroMate"), which consists of a computer-controlled robotic arm, head
stabilizer, presurgical planning workstation and proprietary software used to
position and precisely hold critical tools during stereotactic brain surgery.
The Company continues to market NeuroMate, although no sales have occurred since
the end of the second quarter of 2003. The Company develops specialized
operating software for several implant manufacturing companies. These implant
manufacturers contract with the Company for the development of particular lines
of new prosthesis software to be used with the ROBODOC system. Fees for these
services are recorded as product development revenue as earned.

The Company offers a one-year warranty for parts and labor on all ROBODOC
systems. These warranties generally commence upon the completion of training and
installation. In most cases, the Company's customers purchase a service
contract, which includes extended warranty coverage (parts and labor),
unspecified product maintenance updates, customer support services and various
consumables required during surgical procedures. Customers not covered by
warranties or service contracts are billed on a time and materials basis for
service, and on a per unit basis for products. Revenue related to maintenance
and service contracts is recognized ratably over the duration of the contract.

Results of Operations

For the three-month period ending September 30, 2004, net revenue decreased
approximately 74% or $0.4 million when compared to the three-month period ended
September 30, 2003. Cost of revenue for the same three-month comparative periods
decreased 81% or $0.6 million which resulted in an increase in the gross margin
of 102% or $0.2 million. Operating expenses decreased during the three-month
period ending September 30, 2004 compared to the same three-month period of 2003
by 61% or $0.3 million, with an operating loss of approximately $325,000 and net
loss of approximately $332,000 for the three-month period ended September 30,
2004 as compared to an operating loss of $1,191,000 and net loss of $1,056,000,
respectively, for the same three-month comparative period in 2003. For the
nine-month period ending September 30, 2004, net revenue decreased 75% or $4.1
million when compared to the nine-month period ended September 30, 2003. Cost of
revenue decreased 82% or $3.2 million between the nine-month periods ended
September 30, 2004 and 2003, which resulted in a decrease in the gross margin of
58% or $1.0 million between the comparison periods. Operating expenses decreased
during the nine-month period ending September 30, 2004 compared to the same
nine-month period of 2003 by 53% or $1.0 million, with an operating loss of
approximately $1,035,000 and net loss of approximately $1,045,000 in the current
nine-month period as compared to an operating loss of approximately $1,473,000
and net loss of approximately $1,241,000 for the 2003 nine-month comparative
period.

Net Revenue

Net revenue of $0.5 million for the third quarter of 2003 decreased to $0.1
million for the third quarter of 2004. This 74% decrease for comparative
quarters is due to the loss of almost $0.4 million in net revenue generated by
the Company's European operations, that were liquidated during the fourth
quarter of 2003. The Company recorded no systems sales in the third quarter of
2003 or the third quarter of 2004. The only revenue derived during the third
quarter of 2003 and the third quarter of 2004 was from development projects and
servicing contracts. The revenues generated by service contracts, for the
Company's non-European operations, for the third quarters of 2004 and 2003 was
relatively flat.

Net revenue decreased 75% from $5.5 million during the first nine-months of 2003
to $1.4 million during the first nine months of 2004. The decrease in net
revenue was primarily due to the elimination of $3.0 million in net revenue
generated by the Company's European operations, which were liquidated in
December 2003. The remaining reduction of $1.1 million in revenue in the first
nine months of 2004, when compared to the first nine months of 2003, was
primarily due to a decrease in product development revenue as a result of
decreases in the number of projects and development activity that the Company's
non-European operations were involved in. During the nine-month period ended
September 30, 2003, the Company had recognized revenue on four ROBODOC systems
and four NeuroMate systems while only two ROBODOC systems were sold for the same
nine-month period of 2004. Both of the ROBODOC systems in 2004 were previously
returned units, which were recorded in inventory at a zero dollar value, and
have a lower average selling price when resold.

Cost of revenue

Cost of revenue decreased 81% from $0.7 million during the third quarter of 2003
to $0.1 million during the third quarter of 2004. The decrease in cost of
revenue was primarily due to the elimination of $0.3 million in cost of revenue
generated by the Company's European operations, which were liquidated during the
fourth quarter of 2003. The remaining reduction of $0.3 million in the cost of
revenue in the third quarter of 2004, when compared to the third quarter of
2003, primarily was the result of decreases in headcount and lease facility
expenses allocated to manufacturing.

Cost of revenue for the nine-month period ended September 30, 2004 decreased 82%
to $0.7 million from $3.8 million for the nine-month period ended September 30,
2003. The decrease in the cost of revenue was primarily due to the elimination
of $2.2 million in cost of revenue attributable to the Company's European
operations. The remaining reduction in cost of revenue during the nine-month
period ending September 30, 2004, when compared to the cost of revenue for the
same period of the prior year, primarily was due to the decreases in the number
of units shipped and cost reduction measures initiated during fiscal 2004 which
included reductions in headcount and related expenses.

Gross margin, as a percentage of net revenue, increased from an approximate
negative 31% for the three-month period ending September 30, 2003 to a positive
3% for the three-month period ending September 30, 2004 and increased from a
positive 30% for the nine-month period ending September 30, 2003 to a positive
50% for the nine-month period ending September 30, 2004. The increase for the
three and nine-month periods in 2004 was primarily due to the higher margins the
Company enjoyed on the sale of refurbished units as well as cost reductions
related to reduced headcount and manufacturing overhead costs.

Operating expenses

Total operating expenses have continued to decline as a result of the Company's
cost reduction program and the liquidation of its European operations. Selling
and general administrative expenses are comprised of salaries, commissions,
travel expenses and costs associated with trade shows as well as the finance,
legal and human resources departments and professional support fees for these
functions. Selling and general administrative expenses for the three-month
period ending September 30, 2004 decreased approximately 61% to $0.2 million
from $0.6 million for the three-month period ending September 30, 2003. Selling
and general administrative expenses for the nine-month period ending September
30, 2004 decreased 53% to $1.0 million from $1.9 million for the nine-month
period ending September 30, 2003. The primary factor causing such decreases in


                                       12
<PAGE>


selling, general and administrative expense is the liquidation of the Company's
European operation, which accounted for $0.2 million and $0.6 million of the
decrease for the three and nine-month periods ended September 30, 2003,
respectively. The remaining decrease in selling and general administrative
expense for the three-month period ending September 30, 2004 is due to a
reduction in staffing expense and rent expense. During the third quarter of
2004, the Company renegotiated the lease on its corporate headquarters and
manufacturing facilities to reduce the size of the leased premises and the
leased facilities expense by approximately 50%. In addition to the reduction of
occupancy expense, selling and general administrative expense decreased in the
nine-month period as a result of reduced headcount and commission expense
resulting from lower sales volume.

Research and development expenses are comprised of the engineering and related
costs associated with the development of innovative image-directed
computer-controlled robotic products for surgical applications, along with
specialized operating software and hardware systems to support these products,
quality assurance and testing. Research and development expenses decreased
approximately 80% from $0.5 million to $0.1 million for the three-month periods
ending September 30, 2003 and 2004 respectively. The primary reason for this
decrease was the reduction of the Company's direct and allocated research and
development expenses through downsizing, and an increase in development projects
performed for third-parties whose costs are deferred until the corresponding
revenue is recognized.

Research and development expenses for the nine-month period ended September 30,
2004 decreased approximately 31% from the expenses for the 2003 nine-month
period, after giving effect to $125,000 in grant funding recorded by the Company
as a reduction of research and development expense. The $125,000, which was
received in April 2003, was the final payment under a grant from the National
Institute for Standards and Technology of the United States Department of
Commerce ("NIST"). Under the terms of the NIST grant, the Company was entitled
to reimbursement for certain of the expenses incurred in connection with the
development of its revision hip surgery product. As of December 31, 2003, the
Company had received a cumulative total of approximately $1,221,000 in funding
from NIST since 1995. The Company has recorded the proceeds from the NIST grant
as a reduction of its research and development expenses.

During the three month period ended September 30, 2003, the Company recorded
$135,000 of other income (expense), net, of which $109,000 resulted from a loan
by the French national agency being forgiven. The French agency initially
granted the loan in 1997. Under the terms of the loan, which was established for
the development of a new neurological system, the balance could be forgiven upon
review by the French agency. The remaining income for the three-month period
ended September 30, 2003 resulted from favorable foreign currency exchange
rates. For the nine-month period ending September 30, 2003, other income
(expense), net was approximately $232,000 as compared to ($10,000) for the
nine-month period ending September 30, 2004. The income for the first nine
months of 2003 resulted from the loan forgiven by the French national agency and
favorable currency exchange rate for the Euro related to the Company's business
in Europe. The company was not effected by foreign currency exchange rates
during the three-month and nine-month periods ending September 30, 2004.

Critical Accounting Policies and Estimates

The preparation of the Company's unaudited condensed consolidated financial
statements requires the Company to make estimates and judgments that affect the
reported amounts of assets, liabilities, revenue and expenses, and related
disclosure of contingent assets and liabilities. On an on-going basis, the
Company evaluates the estimates, including those related to bad debts,
inventories, impairment of assets, warranties, contingencies and litigation. The
Company bases these estimates on historical experience and on other assumptions
believed to be reasonable under the circumstances, the results of which form the
basis for making judgments about the carrying values of assets and liabilities
that are not readily apparent from other sources. The Company's management has
discussed these critical accounting policies with the audit committee of the
Company. Actual results may differ from these estimates under different
assumptions or conditions.


                                       13

<PAGE>


The Company believes the following critical accounting policies affect the
Company's more significant judgments and estimates used in the preparation of
the condensed consolidated financial statements:

     The Company recognizes revenue from sales of its products upon the
     completion of equipment installation and training at the end-user's site,
     except when the sales contract requires formal customer acceptance.
     Equipment sales with contractual customer acceptance provisions are
     recognized as revenue upon written notification of customer acceptance,
     which generally occurs after the completion of installation and training.
     Furthermore, due to business customs in Japan and the interpretation of
     Japanese law, all equipment sales to Japanese customers are recognized
     after customer acceptance, which generally occurs after the completion of
     installation and training. Revenue related to maintenance and service
     contracts is recognized ratably over the duration of the contracts.

     The Company periodically evaluates the need for allowances for doubtful
     accounts for estimated losses resulting from the inability of the Company's
     customers to make required payments. If the financial condition of its
     customers were to deteriorate, resulting in an impairment of their ability
     to make payments, additional allowances may be required.

     Where the Company's products are not covered by separate service
     agreements, the Company reserves against the estimated cost of product
     warranties at the time revenue is recognized. The warranty obligation is
     affected by product failure rates, material usage and service delivery
     costs incurred in correcting a product failure. Should actual product
     failure rates, material usage or service delivery costs differ from these
     estimates, revisions to the estimated warranty liability would be required.

     The Company writes down inventory for estimated obsolescence or
     unmarketable inventory equal to the difference between the cost of
     inventory and the estimated market value based upon assumptions about
     future demand and market conditions. If actual market conditions are less
     favorable than those the Company projected additional inventory write-downs
     may be required.

     Property, plant and equipment are amortized over their useful lives. Useful
     lives are based on estimates of the period that the assets will generate
     revenue. Property and equipment are reviewed for impairment whenever events
     or changes in circumstances indicate that the carrying amount of an asset
     may not be recoverable.

Liquidity and Capital Resources

The cash position of the Company is inadequate, and although the Company has
identified potential sources of cash for future operations, there cannot be any
assurance given that the Company will receive these cash amounts, or that these
cash amounts will be sufficient to assure continuing operations. The report of
independent auditors on the Company's December 31, 2003 consolidated financial
statements includes an explanatory paragraph indicating there is substantial
doubt about the Company's ability to continue as a going concern. The Company
believes that it has a plan to address these issues and enable the Company to
continue operating through September 30, 2005. This plan includes obtaining
additional equity or debt financing, increasing product sales in existing
markets, increasing sales of system upgrades, and further reductions in
operating expenses as necessary (see notes 5 and 11). Although the Company
believes that the plan will be realized, there is no assurance that these events
will occur. In the event that the Company is unsuccessful in realizing the
benefits of such plan, it is possible that the Company will cease operations
and/or seek bankruptcy protection. The September 30, 2004 condensed consolidated
financial statements do not include any adjustments to reflect the uncertainties
related to the recoverability and classification of assets or the amounts and
classification of liabilities that may result from an inability of the Company
to continue as a going concern.

At September 30, 2004 the Company's "quick ratio" (cash and accounts receivable
divided by current liabilities), a conservative liquidity measure designed to
predict the Company's ability to pay bills, was only 5%. It has been difficult
for the Company to meet obligations, including payroll, as they come due, and
the Company expects this situation to continue through September 30, 2005. Net


                                       14

<PAGE>


cash used in operating activities was approximately $245,000 for the nine-month
period ended September 30, 2004. This primarily resulted from a net loss of
$1,045,000, an increase in accounts receivable of $219,000, an increase in
inventory of $122,000, and a decrease in unearned income of $129,000 which were
partially offset by increases in accounts payable of $389,000 and an increase in
accrued payroll and related expenses of $677,000 and $100,000 of other current
liabilities and $81,000 decrease in other current assets. The $100,000 in
increase in other current liabilities is directly related to a financing
agreement entered into by the Company on June 15, 2004. (See Note 5 of "Notes to
Condensed Consolidated Financial Statements (unaudited)").

At September 30, 2004, the Company had amounts due to the executive officers of
the Company of approximately $1,146,000, in the aggregate, in the forms of,
deferred salaries, unreimbursed travel expenses and noninterest bearing advance.
Of the $1,146,000, $437,000, $279,000 and $94,000 are included in accrued
payroll and related expense and accounts payable and accrued liabilities,
respectively, due to Ramesh C. Trivedi, president and chief executive officer of
the Company; $132,000, $25,000 and $53,000 are included in accrued payroll and
related expense and accounts payable and accrued liabilities, respectively, due
to Leland Witherspoon, vice president of engineering of the Company; $98,000 and
$28,000 are included in accrued payroll and related expense and accrued
liabilities, respectively, due to Charles J. Novak, chief financial officer of
the Company.

To obtain funding for the Company's ongoing operations, the Company entered into
a securities purchase agreement (the "Agreement") with an accredited investor on
June 15, 2004 with respect to the sale by the Company for aggregate
consideration of $150,000 of (i) a convertible debenture in the principal amount
of $150,000 and (ii) warrants to purchase 1,500,000 shares of Company common
stock. The Agreement contemplates the sale of additional convertible debentures
and warrants upon the occurrence of specific events. The Company is obligated to
register under the Securities Act for resale by the investor the common stock
underlying the debenture and warrants issued pursuant to the Agreement.
In connection with the sale of the original $150,000 convertible debenture and
1.5 million warrants the investor provided the Company with funds as follows:

     o    $100,000 was disbursed to the Company on June 15, 2004;

     o    $50,000 was disbursed to the Company on October 19, 2004; and

     o    $50,000 has been retained by the investor for disbursement to various
          professionals in payment for services to be provided to the Company.


The convertible debenture bears interest at 6 3/4%, matures two years from the
date of issuance, and is convertible into Company common stock at the investor's
option. The convertible debenture is convertible into the number of shares of
Company common stock equal to the principal amount of the debenture being
converted multiplied by 11, less the product of the conversion factor multiplied
by ten times the dollar principal amount of the debenture being converted. The
conversion factor for the convertible debenture is the lesser of (i) $0.25 or
(ii) eighty percent of the average of the five lowest volume weighted average
prices during the twenty (20) trading days prior to the conversion. Accordingly,
there is no limit on the number of shares into which the debenture may be
converted. In addition, the investor is obligated to proportionately exercise,
concurrently with the submission of a conversion notice by the selling
stockholder, the warrants. The warrants are at an exercise price of $1.00 per
share.

The investor has contractually agreed to restrict its ability to convert or
exercise its warrants and receive shares of Company common stock such that the
number of shares of common stock held by it and its affiliates after such
conversion and exercise does not exceed 4.9% of the then issued and outstanding
shares of Company common stock.

The issuance of more than 51.5 million shares of common stock upon conversion of
the convertible debenture and exercise of the warrants issued pursuant to the
Agreement would require the Company to issue shares of common stock in excess of
the Company's currently authorized shares of its common stock. The Company
intends to seek stockholder approval to amend the Company's certificate of


                                       15

<PAGE>


incorporation to increase the Company's authorized common stock from 100,000,000
to 300,000,000 shares. Such solicitation will be made pursuant to a proxy
statement conforming to the rules and regulations of the Securities and Exchange
Commission. This Quarterly Report on Form 10-QSB should not be considered, in
any manner, a solicitation for voting in favor of such an increase in the
Company's authorized common stock.

The issuance of the convertible debenture and warrants to the investor is
contingent upon stockholder approval of the increase in the Company's authorized
common stock. If such approval is not received, the Agreement will terminate and
the Company will be obligated to repay the proceeds received to date and other
funds disbursed by the investor to professionals in payment of services rendered
on behalf of the Company. As a result, the Company recorded such proceeds in
other current liabilities.

On December 14, 2004 the Company entered into a $2.5 million agreement with
Fujifilm Medical Systems, USA ("Fuji") under which Fuji will license the
Company's orthopedic surgical planning technology for its use solely in the
Picture Archiving and Communications Systems ("PACS") market. Under the terms of
the license agreement the Company received $0.5 million in conjunction with the
signing of the agreement. Additional milestone payments totaling $2.0 million
will be paid to the Company over a two-year period, assuming all such milestones
are met.

     Item 3. Controls and Procedures

(a) Under the supervision and with the participation of management, including
the Company's President and Chief Executive Officer and Chief Financial Officer,
an evaluation was made of the effectiveness of the Company's disclosure controls
and procedures, as such term is defined under Rule 13a-15(e) promulgated under
the Securities Exchange Act of 1934, as amended. Based upon that evaluation, the
President and Chief Executive Officer and the Chief Financial Officer concluded
that the Company's disclosure controls and procedures were effective as of the
end of the period covered by this quarterly report.

(b) There has been no change in the Company's internal control over financial
reporting during the quarter ended September 30, 2004 that has materially
affected, or is reasonably likely to materially affect, the Company's internal
control over financial reporting. Part II. Other Information

     Item 1. Legal Proceedings

The Company is subject to legal proceedings and claims that arise in the normal
course of business. The Company cannot assure that it would prevail in such
matters nor can it assure that the Company would have sufficient funds available
to satisfy any adverse judgement. Due to the inherent uncertainties of
litigation, were there any such matters, the Company may not be in the position
at any specific time to accurately predict a litigation's ultimate outcome. As
of September 30, 2004, there were no current proceedings or litigation involving
the Company that the Company believes, if judgement were rendered against the
Company, would have a material adverse impact on its financial position, results
of operations or cash flows.

     Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

During the three-month period ended September 30, 2004, the Company issued
300,000 warrants, which have been valued at $12,000, to outside legal counsel
for such firm foregoing demand for immediate payment to said firm. The Company
believes that the issuance of such warrants was exempt from the registration
requirements of the Securities Act pursuant to the provisions of Section 4(2) of
the Securities Act.
