Part I Item 1. Description of Business Integrated Surgical Systems, Inc. (the "Company") designs, manufactures, sells and services image-directed, computer-controlled robotic software and hardware products for use in orthopaedic and neurosurgical procedures. The Company was incorporated in Delaware in 1990. In 1997, the Company acquired 100% interest in a French company, Innovative Machines International, S.A., involved in the manufacturing and servicing of neurosurgical products and changed the name to Integrated Surgical Systems, S.A. ("ISS-SA"). Under French law, a company whose net assets are less than 50% of its capital stock may come under the supervision and control of a regional administrative tribunal. On September 30, 2003, the Tribunal de Commerce (the "Tribunal") in Lyon, France appointed an administrator to manage the Company's operations and the administrator exercised control over all aspects of ISS-SA's operations including employee retention, purchasing, sales and inventory management. Effective with the administrator's appointment, the Company no longer had access to the assets, personnel or records of ISS-SA. As a result, in the fourth quarter of 2003, the Company recorded a loss of $1,516,519 in connection with the liquidation of its investment in ISS-SA and closure of the Company's European operation. Orthopaedic Applications The Company's principal orthopaedic product, the ROBODOC(R) Surgical Assistant System ("ROBODOC"), integrates the ORTHODOC(R) Presurgical Planner ("ORTHODOC") with a computer-controlled robot for use in joint replacement surgeries. The surgeon uses ORTHODOC, a computer workstation with the Company's proprietary software, for preoperative surgical planning. ORTHODOC converts a computerized tomography ("CT") scan data of the patient's joint into three-dimensional bone images. The surgeon selects a prosthesis from the ORTHODOC prosthesis software library, and manipulates the three-dimensional prosthesis models against the bone image. The ORTHODOC then allows the surgeon to preoperatively visualize the possible results of the surgical outcome. The Company offers software for several lines of prostheses in its software library. Implant manufacturers contract with the Company for the development of prosthesis software. After the surgeon selects the optimal bone cuts and a prosthesis, ORTHODOC creates a surgical plan, which is then up-loaded to the surgical robot. The surgical plan guides the robot as it mills the bone in the operating room. Both hip and knee replacement surgeries involve removing a portion of the bone at the joint, referred to as "milling," to properly replace it with a prosthesis. For hip replacement surgery, a cavity is milled by the robot into which the selected prosthesis is inserted. In the case of knee replacement surgery, ROBODOC mills both the upper and lower leg bone ends for precise and accurate prosthesis placement according to the plan. Neurosurgical Applications The Company entered the neurosurgical equipment sector with the acquisition of Innovative Medical Machines International, S.A., of Lyon, France, in September 1997. This wholly-owned subsidiary, which was renamed Integrated Surgical Systems, S.A. ("ISS-SA"), designed, manufactured, sold and serviced the NeuroMate(TM) System ("NeuroMate"). The Company continues to market NeuroMate, although no sales have occurred since the end of the second quarter of 2003. Based on its experience of over five years in commercializing the NeuroMate System on a worldwide basis, the Company has developed a new strategy for the neurosurgery market. It consists of consolidating different robotic platforms to increase overall functionality while lowering the costs. The Company is planning to offer a new proprietary product to the neurosurgical market on a worldwide basis. Specialized Product Development The Company develops specialized presurgical planning software for several major implant manufacturing companies. These implant manufacturers contract with the Company for the development of software for particular lines of new prostheses to be used with the ROBODOC system. Utilizing its many years of experience in presurgical planning in the 3D mode, the Company has entered the presurgical planning software market for orthopaedics on an OEM basis. The Company offers presurgical planning software for use in stand-alone systems, as well as an integral part of PACS (Picture, Archiving and Communication Systems) commercialized worldwide by all major imaging corporations. 2

Marketing, Sales and Distribution As further discussed in "Government Regulations," ROBODOC cannot be marketed in the United States until it has been cleared by the U.S. Food and Drug Administration (the "FDA"). Accordingly, substantially all of the Company's sales are made to customers located in foreign countries. The Company markets the ROBODOC system to orthopaedic and trauma surgeons and hospitals in Europe through direct sales and through distributors in Japan, Korea and India. The Company promotes the ROBODOC system through presentations at trade shows, advertisements in professional journals and technical and clinical publications, and direct mail campaigns. Presentations to potential customers focus on the clinical benefits to the patient and the potential financial and marketing benefits to hospitals and surgeons. Manufacturing The Company's manufacturing process primarily consists of the assembly of purchased components, integration of proprietary software, product testing and packaging. The Company's manufacturing facility is located in Davis, California. The surgical components of the ROBODOC consist of readily available commercial parts, a customized robot arm, a robot base and a control cabinet. Upon receipt, these and other components are tested and assembled into a complete system. The final assembled product is tested once again before shipment to a customer. One of the key components of the ROBDOC system, a customized Robotic arm, has been manufactured by a Japanese manufacturer, Sankyo Seiki, per ISS specifications. The specifications for this component are the proprietary property of the Company and cannot be used by anyone else to build or supply robot arms. The manufacturer has discontinued their medical robot business, and will not manufacture new robot arms for the Company. This situation does not create immediate risk as the Company has supplies in inventory to meet anticipated demand through December 31, 2005, the Company is redesigning the robot arm and is securing a new vendor for alternative vendor manufacture. Any significant delay in securing a new vendor for this component could have a material adverse effect on the financial condition, results of operations, or cash flow of the Company. ORTHODOC consists of a pre-surgical planning computer workstation and associated data peripherals incorporating the Company's proprietary software. Surgical supplies, including sterile drapes and cutters, are manufactured to the Company's specification by outside vendors. These vendors are inspected periodically by the Company and samples are evaluated to ensure that these specifications are consistently met. The Company and the Company's authorized distributors purchase these items in quantity and distribute them to customers as needed. The Company's production facilities are subject to periodic inspection by the FDA for compliance with Good Manufacturing Practices. The Company is also subject to European manufacturing standards for European sales, and is routinely audited to ensure compliance to the EC Medical Device Directives. All products are shipped bearing the CE Mark, certifying that they meet the European Union's marketing requirement. Research and Development Since inception, the Company's engineering activities have focused on the development of innovative image-directed, pre-surgical planning and computer-controlled robotic products for surgical applications, along with specialized operating software and hardware systems to support these products. The Company incurred research and development expenses of approximately $994,000 during the year ended December 31, 2004, and $1,664,000 in the year ended December 31, 2003. 3

Competition The principal competition for ROBODOC comes from manual surgery performed by orthopaedic surgeons using surgical power tools, navigated instrumentation and manual devices. These tools and devices are manufactured and/or distributed by major orthopaedic companies, including Striker/Howmedica Osteonics (a division of Stryker Corporation), Zimmer, Inc., DePuy, Inc. (a subsidiary of Johnson & Johnson), Smith and Nephew, and Biomet, Inc. Navigational instrumentation systems, offered by the major manufacturers of orthopaedic devices, are an intermediate step between unaided free hand and robotic surgery. Navigational systems use a tracking device affixed to the end of traditional cutting tools to assist the surgeon in visualizing tool positions for bone preparation and implant placement. Since URS GmbH, a German medical robotics company, ceased its operations in 2002, there is no direct competition to the Company's product. Warranty and Service The Company offers a one-year warranty for parts and labor on all ROBODOC systems commencing upon the completion of training and installation, except when the sales contract requires formal customer acceptance. In most cases, the Company's customers purchase service contracts, which include 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 consumable products. The Company's technical staff trains medical professionals in its use of the product and provides field service. Additional technical support is provided by the Company's engineering department. In Europe, the Company has entered into an arrangement with a third party under which it provides warranty and extended warranty services to the Company's customers. For these customers, the Company may receive a royalty payment if the cost of providing such service meets certain threshold levels. Patents and Proprietary Rights The Company relies on a combination of patent, trade secret, copyright and trademark laws and contractual restrictions to establish and protect the Company's proprietary rights in its products and to maintain a competitive position. ROBODOC and ORTHODOC are registered trademarks of the Company. The Company has been issued five U.S. patents, has four U.S. patents pending, and has filed additional patent applications covering various aspects of the technology in Europe and in the United States. U.S. issued patents include: o Computer aided system for revision total hip replacement surgery; o Computer system and method for finish cutting bone cavities; o Computer system and method for positioning a surgical robot; o Computer system and method for cavity generation for surgical planning and initial placement of a bone prosthesis; and o Computer system and method for performing image directed robotic orthopaedic procedures without a fiducial reference system. Significant portions of ORTHODOC and ROBODOC software are protected by copyrights. IBM has granted the Company a perpetual royalty-free license for the underlying software code utilized in ROBODOC. In addition, IBM has agreed not to assert infringement claims against the Company with respect to an IBM patent relating to robotic medical technology, to the extent that this technology is used in its products. The Company has registered the marks ROBODOC and ORTHODOC. 4

The Company cannot guarantee that it will have the necessary working capital to enforce and/or defend its patents, copyrights or trademarks if challenged. Government Regulations The medical devices the Company manufactures and markets are subject to extensive regulation by the FDA and other federal and foreign governmental authorities. The ROBODOC system is approved for use in Europe and carries the European Union's CE Mark. The ORTHODOC is cleared by the FDA for marketing in the United States of America. While ROBODOC has not yet been approved for use by the Japanese regulatory agency, the Ministry of Health, Labor and Welfare ("MHLW"), Japanese hospitals and surgeons are able to purchase and use the systems while approval is pending. The Company completed clinical trials in Japan and submitted a petition for approval in 2002. Although no assurance can be offered, the Company believes the approval can reasonably be expected in late 2005. However, there can be no assurance that the determination will be favorable, or that any determination will not include unfavorable limitations or restrictions. U.S. clinical trials designed to secure FDA clearance to market the ROBODOC system in the U.S. began in December 2000. This trial strategy calls for performing pinless hip (latest version) replacement surgeries on up to 181 subjects. Upon completion, the Company will submit the application to the FDA for clearance to market this ROBODOC product in the United States. At December 31, 2004, a total of 111 patients have been enrolled in this study. In 2003, the Company added a third clinical study site in Buffalo, N.Y., and, with this additional study site, the Company anticipates the completion of clinical trials by the end of 2005, although no assurances can be given. In the fourth quarter of 2004, the principal investigator at the University of Arkansas Medical Science Department in Little Rock, Arkansas passed away. The ROBODOC system has been removed from this clinical site and final preparations are being made to relocate this system to a new clinical site. Products manufactured or distributed pursuant to FDA clearances or approvals are subject to pervasive and continuing regulation by the FDA, including quality system requirements, documentation and reporting of adverse experiences with the use of the device. Device manufacturers are required to register their facilities and list their devices with the FDA and with certain state agencies and are subject to periodic compliance inspections by the FDA and others. Labeling and promotion activities are subject to scrutiny by the FDA and, in certain instances, by the Federal Trade Commission. The Company is also subject to a variety of state laws and regulations in those states or localities where the products are or will be marketed. As is the case with other manufacturers, the Company is subject to numerous federal, state and local laws relating to such matters as safe working conditions, manufacturing practices, environmental protection, fire hazard control and disposal of hazardous or potentially hazardous substances. Although the Company has not been cleared to market the ROBODOC System in the U.S., the Company is permitted to export the system provided certain requirements are met. Products approved for use by European Union member countries, as well as Australia, Canada, India, Israel, Japan, Korea, New Zealand, Switzerland and South Africa, do not require FDA export approval. FDA export approval, when it is required, is granted when certain requirements are met including documentation demonstrating that the product is approved for import into the country to which it is to be exported and, in some instances, safety data from animal or human studies. 5

The introduction of products in foreign markets has subjected the Company, and will continue to subject the Company, to foreign regulatory clearances that vary from country to country. Many countries also impose product standards, packaging requirements, labeling requirements and import restrictions on medical devices. In addition, each country has its own tariff regulations, duties and tax requirements. ROBODOC satisfies international electromedical standard IEC 601-1 and the protection requirements of the Electromagnetic Compatibility Directive (89/336/EEC). The Company has also received ISO 9001 registration, EN 46001 certification, and ED Directive 93/42/EEC Annex II, Article 3 approval. Meeting these standards and requirements, and receiving these certifications and approvals, allows the Company to apply the CE Mark to its products. ROBODOC meets the relevant provisions of the Medical Device Directive for Class IIb Medical Devices. Product Liability Prior to June 2004, the Company maintained product liability insurance in the amount of $10 million per occurrence and $10 million in aggregate. This coverage was cancelled by the insurance carrier in June 2004, due to the Company's financial inability to pay the requisite insurance premiums. Effective March 4, 2005, the Company secured a new product liability insurance policy in the amount of $2 million per occurrence and $2 million in aggregate. The Company is subject to legal proceedings and claims that arise in the normal course of business as is discussed in Item 3 "Legal Proceedings" in this report. Major Customers The Company sells its robotic systems to international distributors, who in turn resell the product to specific international hospitals and clinics. The Company's international distributors are Imatron (KTEC) in Japan, ROCOM Frontier in Korea and Paramount Impex in India. A significant portion of the Company's sales are to a limited number of customers located in foreign countries. Three major foreign customers of the Company accounted for 45%, 24% and 22% of the Company's revenue during the year ended December 31, 2004, and three major foreign customers accounted for 22%, 14% and 13% for the year ended December 31, 2003. At December 31, 2004, two foreign customers accounted for 98% of accounts receivable, and at December 31, 2003, two customers accounted for 100% of accounts receivable. During the first nine months of 2003, the Company sold its products in Europe through its wholly owned subsidiary, ISS-SA. In the fourth quarter of 2003, the Company recorded a loss of $1,516,519 in connection with the liquidation of the Company's European operation. Since December 23, 2003, the Company's Davis, California headquarters office has assumed the sales responsibility for its products in Europe. The Company also develops specialized pre-surgical planning software for several major customers, including DePuy International Limited, Fujifilm Medical Systems USA, Inc, Stryker and Zimmer Inc. Employees On December 31, 2004, the Company had a total of 15 employees: 10 in engineering, 2 in manufacturing and 3 in sales and administration. None of the employees is covered by a collective bargaining agreement and the Company believes that the relationship with its employees is satisfactory. Item 2. Description of Property The Company's executive offices and production facility are located in Davis, California. The Company occupies the facility in Davis under a lease that expires in June 2005, which is currently being renegotiated. The Company can 6

give no assurance that the lease will be extended. If the lease were not extended, the Company would be unable to conduct business until another facility was leased, and there is no assurance That the company will be able to obtain a lease extension or a new lease on terms as favorable to the Company as are provided in the current lease. The Company's failure to secure a lease could have material effect on the business, financial condition, cash flows and results of operations. During the third quarter of 2004, the Company renegotiated this lease to reduce the square footage from approximately 30,500 square feet to approximately 16,000 square feet, with a corresponding per month reduction in monthly rent expense from approximately $32,500 per month to approximately $18,000 per month. Prior to the renegotiations of the lease, the Company paid utilities and maintenance fees directly to the providers of these services. These utility and maintenance fees are now paid by the lessor and billed back to the Company, along with property taxes, on a pro-rated percentage based on the Company's occupancy. Item 3. 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 any remedy could be reached on mutually agreeable terms, if at all. Due to the inherent uncertainties of litigation, the Company would not be able to accurately predict their ultimate outcome. On December 17, 2004, the Company was served with a summons and complaint commenced in Yolo County (California) Superior Court, styled Bischoff, et al. vs. Integrated Surgical Systems, Inc. et al. The plaintiffs' in the litigation, all from Germany, and all of whom were subject to medical treatment which utilized the ROBODOC System, allege that the Company's ROBODOC System is defective and dangerous, both in its manufacture and design and, as a result of such defect and dangerous condition, the plaintiffs sustained injury. The plaintiffs are seeking class status for this matter. The Company believes the plaintiff's allegations are without merit. The Company intends to conduct a vigorous defense against the allegations contained in the complaint. However, the Company did not have any product liability insurance from June 2004 through March 3, 2005, due to its financial inability to pay the requisite insurance premiums. Effective March 4, 2005 the Company secured a new product liability insurance policy in the amount of $2 million per occurrence and $2 million in aggregate. This case is at its incipient stages. The Company has retained competent counsel to represent it in this matter. The amount of damages, if any, are indeterminable at this juncture. Defending against a product liability action can be expensive and time consuming to management personnel. The Company currently does not have the funds, which may be necessary to defend against the plaintiffs' allegations. The failure to properly defend the Company against the allegations could result in a material judgement against the Company, which could adversely affect our financial condition, results of operation and cash flows. The Company may also currently not have the funds necessary to satisfy any judgement rendered against it. The Company's failure to successfully defend against the allegations could result in our seeking protection under the United States Bankruptcy Code. Such action could have a material adverse effect on the market price of the Company's common stock, business, financial condition, cash flow and results of operations. Item 4. Submission of Matters to a Vote of Security Holders None 7

Part II. Item 5. Market for Common Equity and Related Stockholder Matters and Small Business Issuers Purchase of Equity Market Information for Common Stock On May 24, 2004, the OTC Bulletin Board discontinued the quotation of the Company's stock on its system due to our failure to file our annual report on a timely basis. The Company's stock then began to be quoted, and continues to be quoted on the pink sheets, under the trading symbol "RDOC." The following table sets forth the high and low sales prices, as reported on the by the NASDAQ on-line web site www.NASDAQ. com, for shares of the Company's common stock for the periods indicated. Such prices reflect inter-dealer prices, without retail mark-up, mark-down or commission and may not represent actual transactions. Common Stock (RDOC) ---------------------- Fiscal Year Ended High Low December 31, 2004 ------ ------ ----------------- First Quarter $0.130 $0.060 Second Quarter $0.115 $0.050 Third Quarter $0.080 $0.050 Fourth Quarter $0.070 $0.035 Fiscal Year Ended December 31, 2003 ----------------- First Quarter $0.055 $0.022 Second Quarter $0.044 $0.025 Third Quarter $0.055 $0.038 Fourth Quarter $0.190 $0.040 As of April 11, 2005 there were 268 holders of record of the common stock. Dividends The Company has never paid dividends on its common stock and its present policy is to retain anticipated future earnings for use in its business. Recent Sale of Unregistered Securities During the twelve-month period ended December 31, 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. Equity Compensation Plans The following table provides information as of the fiscal year ended December 31, 2004 with respect to the Company's compensation plans (including individual compensation arrangements). 8

Item 6. Management's Discussion and Analysis or Plan of Operation The following discussion and analysis relates to the consolidated operations of the Company and should be read in conjunction with the consolidated financial statements of the Company, including the notes thereto, appearing elsewhere in this report. Results of Operations (2004 vs. 2003) Revenue of $2.4 million for the year ended December 31, 2004 was down 60% when compared to $5.8 million for the year ended December 31, 2003 primarily due to the decrease in product sales. Cost of revenue of $0.9 million for the year ended December 31, 2004 was down $3.1 million when compared to $4.0 million for the year ended December 31, 2003, primarily due to the decreased level of product sales. Operating expenses of $2.1 million for the year ended December 31, 2004 decreased by $3.5 million when compared to the year ended December 31, 2003. This decrease of $3.5 million in operating expenses was comprised of $1.3 million decrease in selling, general and administrative expense, $0.7 million decrease in research and development expense, and a $1.5 million decrease in non-recurring charges. The $1.5 million decrease in non-recurring charges was related to the one-time loss on disposal of subsidiary resulting from the liquidation of the Company's investment in ISS-SA and closure of its European operations in the fourth quarter 2003. Other income, net for the year ended December 31, 2004, decreased by $0.4 million when compared to $0.5 million for the year ended December 31, 2003, primarily due to non-recurring events, including the forgiveness of a $0.1 million loan and a gain of $0.2 million for the reversal of a reserve for clinical robots. These changes in revenue and expenses resulted in a net loss of $0.6 million for the period ended December 31, 2004 as compared to a loss of $3.3 million in the prior year. The decrease in revenue of approximately $3,471,000 in 2004 from 2003 is presented in the following table: 9

2004 2003 Increase (Decrease) ------------------- -------------------- -------------------- Units Units Units Sold Revenues Sold Revenues Sold Revenues ----- ----------- ----- ----------- ----- ----------- ROBODOC System 2 $ 793,000 4 $ 2,547,000 (2) $(1,754,000) ROBODOC Modules 3 262,000 -- -- 3 262,000 NeuroMate Systems -- -- 4 827,000 (4) (827,000) ----- ----------- ----- ----------- ----- ----------- Total Systems and Modules 5 1,055,000 8 3,374,000 (3) (2,319,000) ----- ----------- ----- ----------- ----- ----------- Service contracts, parts and consumables 547,000 1,907,000 (1,360,000) Development revenues 758,000 550,000 208,000 ----------- ----------- ----------- Total Revenues $ 2,360,000 $ 5,831,000 $(3,471,000) =========== =========== =========== The decrease in ROBODOC systems of two units in 2004, compared to four units in 2003, and the decrease in revenues from service contracts and consumables of approximately $1,360,000 in 2004 when compared to 2003 is directly related to the negative publicity in Germany concerning routine surgical complications in which the ROBODOC was used starting in late 2002, 2003 and 2004, that lead to the current law suit. Although no NeuroMate units have been sold since the second quarter of 2003, the Company continues to market this product. Development revenue of approximately $758,000 for the year ended December 31, 2004 was up 38% when compared to approximately $550,000 for the year ended December 31, 2003, due to completion of a greater number of projects. The FDA allows the Company to market NeuroMate as described in the Company's 510(k) pre-market notification. The gross margin for 2004 was 62% compared to 32% in 2003. The increase was primarily due to a reduction in manufacturing costs and overhead charged to cost of revenue, an increase in revenue from higher margin development projects, the sale of two refurbished ROBODOC Systems. The Company charges its manufacturing expense and overhead directly to cost of revenue due to its low manufacturing volume. During 2004, the Company reduced its work force and operating costs and, as a result, manufacturing expenses and overhead were reduced. The cost to manufacture a refurbished system is considerably less than the cost to manufacture a new system. For the year ended December 31, 2004, ROBODOC and NeoroMate systems generated 45% of revenues compared to 58% for the year ended December 31, 2003. Service contracts, parts, consumables and development revenues were 55% for the year ended December 31, 2004 as compared to 42% for the year ended December 31, 2003. The Company's margins for its service contracts, parts, consumables and development projects are substantially higher than margins on ROBODOC and NeuroMate systems. Selling and general and administrative expenses are comprised of salaries, commissions, travel expenses and costs associated with trade shows as well as its finance, legal and human resources functions. Selling and general administrative expenses for the year ended December 31, 2004 decreased 53% to $1,140,000 from $2,439,000 for the year ended December 31, 2003. The decrease in selling, general and administrative expenses was primarily due to a decrease in average staffing levels in the year ended December 31, 2004 due to attrition and the inability to replace employees due to the lack of working capital. 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 40% to $994,000 during the year ended December 31, 2004 as compared to $1,664,000 for the year ended December 31, 2003. The decrease in the year ended December 31, 2004 is due to decreased staffing and staffing related expenses due to attrition and the inability to replace employees due to the lack of working capital. Restatement of Interim Financial Information In conjunction with the audit of its financial statements for the year ended December 31, 2004, the Company determined that it had overstated accounts receivable and unearned income as of September 30, 2004 due to prematurely or incorrectly recording certain service contracts with its customers. Accounts 10

receivable and unearned income as of September 30, 2004 were overstated by $287,897 and $253,933, respectively. In the third quarter of 2004, net revenue was overstated by $33,964 and net loss understated by a similar amount, as a result of the amortization related to these service contracts. There was no impact on the reported amount of basic or diluted net loss per common share as a result of the correction. (See Note. 13. Unaudited Interim Financial Information (Restated) in Notes to Consolidated Financial Statements) Liquidity The reports of the Company's Independent Registered Public Accounting Firm on the 2004 and 2003 consolidated financial statements included explanatory paragraphs stating that there is substantial doubt with respect to the Company's ability to continue as a going concern. The Company believes that it has a plan to address these issues which will enable the Company to continue to operate through December 31, 2005. This plan includes obtaining additional equity or debt financing, increasing sales of the products in existing markets, increasing sales of system upgrades, and reducing operating expenses as necessary. 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, it is possible that it will cease operations or seek bankruptcy protection. The 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 on the Company's part to continue as a going concern. Through December 31, 2004, the Company has been funded through cash from operations and sales of equity securities (see, "Capital Resources"). At December 31, 2004, the "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 .18. It has been difficult for the Company to meet financial obligations, including payroll, as they come due, and the Company expects this situation to continue through 2005. Net cash provided by operating activities was $1,079,000 for the year ended December 31, 2004. This resulted from the net loss of $556,000, adjusted for non cash transactions of $21,000 for depreciation and $21,000 for stock compensation for non-employees. The primary changes in operating assets and liabilities were decreases in accounts receivable and other current assets of $133,000, increases in accounts payable of $211,000, accrued payroll and related expenses of $425,000 and other income of $1,074,000 offset by an increase in inventory of $159,000 and a decrease in accrued liabilities of $95,000. The increase in unearned income was primarily due to a December 2004 software license agreement with a customer. The increase in inventory was due to the capitalization of development project costs and the increase in accounts payable and accrued payroll and related expense is directly related to the lack of cash. Accrued liabilities decreased primarily as the result of accrued expenses transitioning to accounts payable. The increase in cash from financing activities of $96,000 was primarily due to the receipt of $150,000 received per a securities agreement (as defined in Item 6. Capital Resources) offset by repayment of loans which had been advanced by the officers of $56,000. The Company also received $3,000 from the exercising of stock options by former employees. The cash balance of $1,324,000 at December 31, 2004 was the result of a late December 2004 cash receipt for software development and licensing, and was mostly disbursed during the first quarter of 2005 to pay down existing liabilities. The Company expects to derive most of the cash required to support operations through sales of ROBODOC systems, continued conversion of the inventory balance into cash, collection of accounts receivable and through additional financing. It is critical for the Company to obtain cash from these sources. There can be no assurance given that the Company can continue to convert inventory, collect receivables or raise additional funds on acceptable terms or at all. 11

The Company has the following contractual obligations and commercial commitments at December 31, 2004: less than greater than Total 1 year 1-3 years 3 years ----- ------ --------- ------- Facility operating leases $90,017 $90,017 $0 $0 The Company will require substantial funds for operating activities, further product development, future clinical trials, regulatory approvals, litigation expenses and marketing of its products. The Company's future capital requirements will depend upon the progress of its research and development programs; the time and costs involved in securing regulatory approvals; the cost of filing, defending and enforcing intellectual property rights; and competing technology and market developments. Future expenditures for product development and clinical trials are discretionary and, accordingly, can be adjusted, as can certain selling, general and administrative expenses, based on the availability of cash. At December 31, 2004, the Company had an aggregate amount due to executive officers of approximately $1,013,000. These amounts due are in the form of deferred salaries and unreimbursed travel expenses. Of such amounts, $460,000 and $276,000 are included in accrued payroll and related expense and accounts payable and accrued liabilities, respectively, and are due to Ramesh C. Trivedi, president and chief executive officer of the Company; $141,000 and $27,000 are included in accrued payroll and related expense and accounts payable, respectively, and are due to Leland Witherspoon, vice president of engineering of the Company; and $109,000 is included in accrued payroll and related expense and is due to Charles J. Novak, chief financial officer of the Company. At December 31, 2004, the Company had accrued payroll and accrued payroll taxes of $479,000 for all other employees. Capital Resources On April 11, 2005, there were 45.1 million shares of the Company's common stock outstanding, and is listed on the pink sheets at $0.02 a share, giving the Company a market capitalization of $0.9 million. In the first quarter of 2001, the Company's common stock and warrants were delisted by the Nasdaq because the stock did not maintain the market's minimum bid price of $1.00 per share. On May 24, 2004, the OTC Bulletin Board ceased quoting the Company's stock due to the failure of the Company to file its annual report on Form 10-KSB on a timely basis. Securities traded at less than $5.00 and not traded on a national securities exchange or quoted on the Nasdaq are called "penny stocks". The Securities and Exchange Commission rules require brokers to provide specified information to purchasers of penny stocks, and these disclosure requirements and the requirement that brokers must make a special written determination that the penny stock is a suitable investment for the purchaser and receive the purchaser's written agreement to the transaction in advance may have the effect of reducing trading activity in the common stock and making it more difficult for investors to sell the shares of the Company's stock. 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. 12

The convertible debenture bears interest at 6 3/4%, matures two years from the date of issuance, and is convertible into, at the investor's option, 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 Annual Report on Form 10-KSB 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 $2.1 million in December 2004. Additional milestone payments totaling $0.4 million will be paid to the Company over a two-year period, assuming all such milestones are met. At December 31, 2004, the Company had 168 shares of convertible preferred stock outstanding. Each share of preferred stock has a stated value of $1,000 and is convertible into common stock at a conversion price equal to 80% of the lowest sale price of the common stock over the five trading days preceding the date of conversion. Because there is no minimum conversion price, there is no limit on the number of shares of common stock that holders of preferred stock may acquire upon conversion. The holders of the preferred stock could also engage in short sales of the common stock after delivering a conversion notice to the Company, which could contribute to a decline in the market price of the Company's common stock and give them the opportunity to profit from that decrease by covering their short position with the converted shares acquired at a 20% discount to the prevailing market price. This activity, or the possibility of such activity, could exacerbate any decline or impede any increase in the market price of the Company's common stock. 13

Critical Accounting Policies and Estimates The Company's discussion and analysis of the financial condition and results of operations are based upon the Company's audited consolidated financial statements included elsewhere in this Form 10-KSB and have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of such audited consolidated financial statements requires the Company to make estimates and judgments that affect the reported amounts of the Company's 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 has discussed its critical accounting policies with the audit committee of the Company. Actual results may differ from these estimates under different assumptions or conditions. The Company believes the following critical accounting policies affect the Company's more significant judgments and estimates used in the preparation of the 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 Japan 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. Development projects are accounted for under the provisions of Statement of Position ("SOP") 81-1, "Accounting for Performance of Construction-Type and Certain Production-Type Contracts," using the completed contract and percentage of completion method of accounting. The Company maintains 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 the 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 the 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. 14

Recent Accounting Pronouncements In November 2004, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standard (SFAS) No. 151, "Inventory Costs--An Amendment of ARB No. 43, Chapter 4". SFAS No. 151 amends the guidance in ARB No. 43, Chapter 4, "Inventory Pricing," to clarify the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage). Among other provisions, the new rule requires that items such as idle facility expense, excessive spoilage, double freight, and re-handling costs be recognized as current-period charges regardless of whether they meet the criterion of "so abnormal" as stated in ARB No. 43. Additionally, SFAS No. 151 requires that the allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. SFAS No. 151 is effective for fiscal years beginning after June 15, 2005. The Company is currently evaluating the effect that the adoption of SFAS No. 151 will have on its consolidated results of operations and financial condition but does not expect SFAS No. 151 to have a material impact. In December 2004, the FASB issued SFAS No. 123R (revised 2004),"Share-Based Payment," which replaces SFAS No. 123, "Accounting for Stock-Based Compensation," and supercedes Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees." SFAS No. 123R requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values beginning with the first interim or annual period that begins after December 15, 2005, with early adoption encouraged. The pro forma disclosures previously permitted under SFAS No. 123 no longer will be an alternative to financial statement recognition. The Company is required to adopt SFAS No. 123R beginning January 1, 2006. As of the effective date, the Company will be required to expense all awards granted, modified, cancelled or repurchased as well as the portion of prior awards for which the requisite service has not yet been rendered, based on the grant-date fair value of those awards as calculated for pro forma disclosures under SFAS No. 123. The Company will apply SFAS No. 123R using a modified version of prospective application. Under this method, compensation cost is recognized on or after the required effective date for the portion of outstanding awards for which the requisite service has not yet been rendered, based on the grant-date fair value of those awards calculated under SFAS No. 123 for either recognition or pro forma disclosures. Under SFAS No. 123R, the Company must determine the appropriate fair value model to be used for valuing share-based method to be used at date of adoption. The Company is evaluating the requirements of SFAS No. 123R and expects that the adoption of SFAS No. 123R will have a material impact on the Company's consolidated results of operations and earnings per share. The Company has not yet determined the method of adoption or the effect of adopting SFAS No. 123R, and it has not determined whether the adoption will result in amounts that are similar to the current pro forma disclosures under SFAS No. 123. Risk Factors and Cautionary Statement Regarding Forward-Looking Information The Company cautions that this Form 10-KSB contains "forward-looking statements," within the meaning of the Private Securities Litigation Reform Act of 1995, that involve risks and uncertainties. The Company's plans, strategies, objectives, expectations and intentions are subject to change at any time at the discretion of management and the board of directors. The plans and results of operations will be affected by the Company's ability to manage any growth and working capital and the ability to finance future operations, none of which is assured. In addition, the risk factors that follow may affect the actual results and may cause actual results to differ materially from those expressed in or implied by any forward-looking statement. These risk factors are not an exhaustive list. Additional factors are discussed elsewhere in this Form 10-KSB and also from time to time in the Company's filings with the Securities and Exchange Commission. The Company undertakes no obligation to update such factors in the future. The reports of the Company's Independent Registered Public Accounting Firm on the 2004 and 2003 consolidated financial statements included explanatory paragraphs stating that there is substantial doubt with respect to the Company's ability to continue as a going concern. The Company has a plan to address these issues which it believes will enable the Company to continue to operate through December 31, 2005. This plan includes obtaining additional equity or debt financing, increasing sales of the products in existing markets, increasing sales of system upgrades, and reducing operating expenses as necessary. 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, it is possible that the Company will cease operations or seek bankruptcy protection. 15

The 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 on the Company's part to continue as a going concern. The Company's facility lease expires on June 2, 2005. The Company's seven-year lease, of its executive offices and production facility located in Davis, California, will expire on June 2, 2005. The Company is currently negotiating with the lessor of the facility to extend the lease beyond June 2, 2005. The Company can give no assurance that the lease will be extended. If the lease were not extended, the Company would be unable to conduct business until another facility was leased, and there is no assurance That the company will be able to obtain a lease extension or a new lease on terms as favorable to the Company as are provided in the current lease. The Company's failure to secure a lease could have material effect on the business, financial condition, cash flows and results of operations. The Company's future financial performance will depend almost entirely on sales of the ROBODOC system. The Company expects to derive most of its near-term revenue from sales of the ROBODOC System. Having recognized revenue on two ROBODOC systems in 2004 and four ROBODOC systems in 2003, the Company must develop an effective sales and marketing organization and expend sufficient funds to inform potential customers of the distinctive characteristics and advantages of using the system instead of traditional surgical tools and procedures. Because the ROBODOC system employs innovative technology rather than an improvement of existing technology, and because it represents a substantial capital expenditure, the Company expects to encounter resistance to change, which it must overcome if the system is to achieve significant market acceptance. Furthermore, the Company's ability to market the ROBODOC System in the U.S. is dependent upon clearance by the FDA. The Company can give no assurance that it will receive FDA clearance, or that the ROBODOC System will achieve the market acceptance in the U.S. and foreign markets to generate sufficient revenue to secure profitability. The Company is dependent on foreign sales. Most of the sales have been to customers in Europe and Asia. Until such time, if ever, as the Company receives clearance from the FDA to market the ROBODOC System in the U.S., it will continue to be subject to the risks of foreign sales. These risks include economic or political instability, shipping delays, fluctuations in foreign currency exchange rates, changes in regulatory requirements, customs duties and export quotas and other trade restrictions. Any of these risks could have a material adverse effect on the Company's business. The Company's quarterly revenue and results of operations may fluctuate and may not be indicative of expected revenue and results of operations for the full year. The level of revenue and results of operations fluctuate with the number of ROBODOC Systems sold and development project revenue recognition. The number and timing of the systems sold may cause revenue and earnings to vary significantly on a quarterly basis and a quarter's results may not be indicative of revenue and earnings for the full year. The Company may not be able to secure the regulatory approvals needed to expand the sales of the products to new foreign markets. The introduction of the products in foreign markets has subjected and will continue to subject the Company to foreign regulatory approvals. These approvals may be unpredictable and uncertain and may impose substantial additional costs and burdens. Many countries also impose product standards, packaging requirements, labeling requirements and import restrictions on medical devices. The Company can give no assurance that any of the products will receive further approvals. The Company needs, but has not yet secured, clearance from the FDA under 510(k) petition to market the ROBODOC System in the U.S. In December 2000, the Company began U.S. clinical trials designed to demonstrate that the ROBODOC System is safe and effective for its intended use as an alternative to other surgical power tools and manual devices used in hip replacement surgery. The trials anticipate the completion of hip replacement surgeries in a total of up to 181 16

subjects performed at up to four clinical trial sites. The Company has established three sites, Sutter General Hospital in Sacramento, California, the University of Arkansas in Little Rock, Arkansas and Buffalo General Hospital in Buffalo, New York. In the fourth quarter of 2004, the principal investigator at the University of Arkansas Medical Science Department in Little Rock, Arkansas passed away. The ROBODOC system has been removed from this clinical site and final preparations are being made to relocate this system to a new clinical site. As of December 31, 2004, approximately 61% of the mandated total surgeries have been performed. The Company can provide no assurance that, at the completion of the clinical trials, the FDA will grant clearance to market the system in the U.S. and that such clearance will not include unfavorable limitations or restrictions. In addition, FDA clearance gives no assurance of market acceptance or that the Company will generate gross margins to obtain profitability. Even after receipt of any FDA clearance to market, the Company expects that the FDA may consider any new ROBODOC surgical applications to be new indications for use, which generally require FDA clearance prior to marketing. The FDA may require additional trials before allowing the Company to incorporate new imaging modalities (such as ultrasound and MRI) or other different technologies in the ROBODOC System. The FDA may require new clinical data to support new indications and may require new clinical data for clearance of enhanced technological characteristics. The Company may not be able to comply with quality system and other FDA reporting and inspection requirements. Although the Company believes it is in full compliance with the regulatory requirements in the markets in which it participates, there can be no assurance that the Company will be able to continue to comply with these requirements. Assuming that the Company secures the necessary FDA clearances for the products, in order to maintain these clearances the Company must, among other things, register its establishment and list the devices with the FDA and with certain state agencies. The Company must maintain extensive records, report any adverse experiences on the use of the products and submit to periodic inspections by the FDA and state agencies. The Food, Drug and Cosmetic Act also requires devices to be manufactured in accordance with the quality system regulation, which sets forth good manufacturing practices requirements with respect to manufacturing and quality assurance activities. Noncompliance with FDA requirements can result in fines, injunctions, civil penalties, recall or seizure of products, total or partial suspension of production, failure of the government to grant pre-market clearance or pre-market approval for devices, withdrawal of marketing clearances or approvals, and criminal prosecution. The FDA also has the authority to request repair, replacement or refund of the cost of any device the Company manufactures or distributes. The manufacture and sale of medical products exposes the Company to the risk of significant damages from product liability claims. On December 17, 2004, the Company was served with a summons and complaint commenced in Yolo County (California) Superior Court, styled Bischoff, et al. vs. Integrated Surgical Systems, Inc. et al. The plaintiffs, in the litigation, all from Germany, allege that the Company's ROBODOC System is defective and dangerous, both in its manufacture and design and, as a result of such defect and dangerous condition, the plaintiff, all of whom were subject to medical treatment utilized the ROBODOC System, sustained injury. The plaintiffs are seeking class status for this matter. The Company believes the plaintiff's allegations are without merit. The Company intends to conduct a vigorous defense against the allegations contained in the complaint. However, the Company did not have any product liability insurance from June 2004 through March 3, 2005, due to its financial inability to pay the requisite insured premiums. Effective March 4, 2005, the Company secured a new product liability insurance policy in the amount of $2 million per occurrence and $2 million in aggregate. This case is at its incipient stages. The Company has retained counsel to represent it in this matter. The amount of damages, if any, are indeterminable at this juncture. 17

Defending against a product liability action can be expensive and time consuming to management personnel. The Company currently does not have the funds which may be necessary to defend against the plaintiffs' allegations. The failure to properly defend the Company against the allegations could result in a material judgement against the Company which could adversely affect our financial condition and results of operation. The Company also may currently not have the funds necessary to satisfy any judgement rendered against it. The Company's failure to successfully defend against the allegations could result in our seeking protection under the United States Bankruptcy Code. Such action could have a material adverse effect on the market price of the Company's Common Stock. The Company has produced a limited number of commercial ROBODOC Systems and may not be able to manufacture the systems at a cost or in such quantity as will be necessary for profitable operation. Manufacturers often encounter difficulties in scaling up for manufacturing new products, including problems involving product yields, quality control and assurance, component and service availability, adequacy of control policies and procedures, lack of qualified personnel, compliance with FDA regulations, and the need for further FDA approval of new manufacturing processes and facilities. The Company can give no assurance that production yields, costs or quality will not be adversely affected as the Company seeks to increase production, and any such adverse effect could have a material adverse effect on the business, financial condition, cash flows and results of operations. The Company is dependent on the suppliers of robots. Although the Company has multiple sources for most of the components, parts and assemblies used in the systems, one of the key components of the ROBDOC system has been manufactured by a Japanese manufacturer, Sankyo Seiki, per ISS specification. The specifications, for this component, are the proprietary property of the Company and can not be used by anyone else to build or supply robot arms. The manufacturer has discontinued their medical robot business, and will not manufacture new robot arms for the Company. This situation does not create immediate risk as the Company has supplies in inventory to meet anticipated demand through December 31, 2005 and, the Company is redesigning the robot arm and is securing a new vendor for alternative vendor manufacture. Any significant delay in securing a new vendor for this component could have a material adverse effect on the financial condition, results of operations, or cash flow of the Company. The Company depends heavily on the principal members of its management team and engineers. The Company's growth and future success will depend in large part on the continued contributions of key technical and senior management personnel. Dr. Ramesh Trivedi, the Company's President and Chief Executive Officer, Charles J. Novak, the Company's Chief Financial Officer and Leland Witherspoon, the Company's Vice President, Engineering, are employed pursuant to employment agreements terminable by the Company or by such officer at any time. None of the executives or technical personnel, other than Dr. Trivedi, Mr. Novak and Mr. Witherspoon are employed pursuant to an employment agreement. The loss of the services of Dr. Trivedi, Mr. Novak, Mr. Witherspoon or other senior management or key technical personnel could have a material adverse effect on the business, financial condition, cash flows and results of the Company's operations. The Company's success may depend, in part, on its ability to defend its intellectual property. The Company has secured patent and other proprietary right protection for the technologies and relies on trade secrets, proprietary know-how and continuing technological innovation to develop the products. Any defense of the intellectual property could be costly and require significant time and the attention of the management and technical personnel. Purchases of the Company's shares are subject to the SEC's penny stock rules. Securities traded at less than $5.00 and not traded on a national securities exchange or quoted on the Nasdaq are called penny stocks. The Securities and Exchange Commission rules require brokers to provide information to purchasers of penny stocks, and these disclosure requirements and the requirement that brokers must make a special written determination that the penny stock is a suitable investment for the purchaser and receive the purchaser's written 18

agreement to the transaction in advance may have the effect of reducing trading activity in the common stock and make it more difficult for investors to sell. On May 24, 2004, the OTC Bulletin Board ceased quoting the Company's stock due to the Company's failure to file its annual report on a timely basis. Since that time, the Company's common stock has traded on the pink sheets (symbol "RDOC"). As a result, the market liquidity for the Company's securities is severely adversely affected by limiting the ability of broker-dealers to sell our securities and the ability of stockholders to sell their securities in the secondary market. Impact of issuing additional shares. The Company is seeking additional financing that may require issuing additional common or preferred shares of the Company. Although the dilution factor cannot be determined until the amount of shares are known, there will be a dilution of some unknown magnitude. Additional financing also could result in a change of control 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, at the investor's option, 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 Annual Report on Form 10-KSB should not be considered, in any manner, a solicitation for voting in favor of such an increase in the Company's authorized common stock. 19

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. Item 7. Financial Statements The financial statements follow Item 14 of this report. Item 8. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure The Company did not have any changes in or disagreements with the accountants on accounting and financial disclosure. Item 8A. Controls and Procedures An evaluation was performed, as of December 31, 2004, under the supervision and with the participation of the Company's management, including its Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company's disclosure controls and procedures. Based on such evaluation, the Company's management has concluded that its disclosure controls and procedures were effective as of December 31, 2004, except as described in the following paragraph. In connection with the audit of the Company's financial statements for the fiscal year ended December 31, 2004, the Company's independent registered public accounting firm identified weakness relating to the Company's documentation of its sales contracts with some of its customers. The Company has encountered difficulties in some instances in dealing with the cultural nuances involved in conducting business with some foreign customers. The Company will endeavor to resolve this issue by December 31, 2005. We expect that these efforts will, over time, positively address the weakness noted by our independent auditors. There have been no significant changes in the Company's internal controls or in other factors that could significantly affect the Company's internal controls subsequent to December 31, 2004. Item 8B.

Stock options have a 10-year term, except for Dr. Trivedi which have a 5-year term, and vest periodically over a period not to exceed five years. (2) As required by SEC rules, these columns show the potential gains that may exist for respective options, assuming that the market price for Integrated Surgical Systems, Inc.'s common stock appreciates from the date of grant to the end of the option terms at the annual rates of 5% and 10%, respectively. These numbers are not estimates of the Company's future stock price performance and are not necessarily indicative of the Company's future stock price performance. If the price of the Company's common stock does not increase above the exercise price, no value will be realizable from these options. The following table summarizes, for each of the Named Executive Officers, the total number of unexercised options held at December 31, 2004, and the aggregate dollar value of in-the-money, unexercised options, held at December 31, 2004. The value of the unexercised in-the-money options at December 31, 2004, is the difference between their exercise or base price and the value of the underlying common stock on December 31, 2004. The closing sale price of the common stock on December 31, 2004 was $0.035 per share. 25

REPORT OF MACIAS GINI & COMPANY LLP, INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Directors and Stockholders Integrated Surgical Systems, Inc. We have audited the accompanying consolidated balance sheet of Integrated Surgical Systems, Inc. as of December 31, 2004, and the related consolidated statements of operations, convertible preferred stock and stockholders' deficit, and cash flows for the years ended December 31, 2004 and 2003. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Integrated Surgical Systems, Inc. as of December 31, 2004, and the results of its operations and its cash flows for the years ended December 31, 2004 and 2003 in conformity with accounting principles generally accepted in the United States of America. The accompanying financial statements have been prepared assuming that Integrated Surgical Systems, Inc. will continue as a going concern. As more fully described in Note 2, the Company has incurred recurring operating losses, has a working capital deficit of $5,749,062 and an accumulated deficit of $68,287,471 as of December 31, 2004. In addition, as more fully described in Note 11, the Company is a defendant in a product liability lawsuit. The amount of damages, if any, related to the lawsuit is indeterminable. The Company may not be covered by insurance for legal fees, and damages, if any, related to this lawsuit. The Company does not have the funds, which may be necessary to defend itself against the plaintiffs claim, or satisfy any judgment against it. These conditions raise substantial doubt about the Company's ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 2. The financial statements do not include any adjustments that may result from the outcome of this uncertainty. /s/ MACIAS GINI & COMPANY LLP Sacramento, California April 15, 2005 33

Integrated Surgical Systems, Inc. Notes to Consolidated Financial Statements Note 1. Description of Business and Basis of Presentation Integrated Surgical Systems, Inc. ("the Company") designs, manufactures, sells and services image-directed, pre-surgical planning computer-controlled robotic software and hardware products for use in orthopaedic and neurosurgical procedures. The Company was incorporated in Delaware in 1990. In 1997, the Company acquired 100% interest in a French company, Innovative Machines International, S.A., involved in the manufacturing and servicing of neurosurgical products and changed the name to Integrated Surgical Systems, S.A. ("ISS-SA"). Under French law, a company whose net assets are less than 50% of its capital stock may come under the supervision and control of a regional administrative tribunal. On September 30, 2003, the Tribunal de Commerce (the "Tribunal") in Lyon, France appointed an administrator to manage the Company's operations and the administrator exercised control over all aspects of ISS-SA's operations including employee retention, purchasing, sales and inventory management. Effective with the administrator's appointment, the Company no longer had access to the assets, personnel or records of ISS-SA. As a result, in the fourth quarter of 2003, the Company recorded a loss of $1,516,519 in connection with the liquidation of its investment in ISS-SA and closure of the Company's European operation. The results of operations of ISS-SA are only included for the nine-months ended September 30, 2003, reflecting the Company's liquidation of its operations concurrent with the assumption of the Tribunal. The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiary Integrated Surgical Systems, BV ("ISS-BV") for the years ended December 31, 2004 and 2003. All significant intercompany balances and transactions have been eliminated. Note 2. Results of Operations and Management's Plans The Company had net losses of $556,262 and $3,250,219 for the years ended December 31, 2004 and 2003, respectively. In addition, the Company had a working capital deficit of $5,749,062 and an accumulated deficit of $68,287,471 at December 31, 2004. In addition, as more fully described in Note 11, the Company is a defendant in a product liability lawsuit. The report of Independent Registered Public Accounting Firm on the Company's December 31, 2004 and 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 December 31, 2005. This plan includes effecting the issuance of additional convertible debentures and warrants as described in Note 5, seeking additional sources of equity or debt financing, generating cash flows through product, system upgrade and technology sales and continued limitation of discretionary expenditures. Although the Company believes that the plan will be realized, there is no assurance that these events will occur, or that the plan will generate the necessary funds to allow the Company to defend itself against, or satisfy any judgment resulting from the product liability lawsuit (see Note 11). In the event that the Company is unsuccessful, it is possible that it will cease operations or seek bankruptcy protection. The 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 on the Company's part to continue as a going concern. Note 3. Significant Accounting Policies Revenue Recognition Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable and collectability is reasonably assured. 38

Integrated Surgical Systems, Inc. Notes to Consolidated Financial Statements Revenue for product sales is generally recognized upon completion of training and installation of the equipment 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 training and installation. Furthermore, due to business customs in Japan and the Company's interpretation of Japanese law, all equipment sales to Japan are recognized after customer acceptance, which generally occurs after the completion of training and installation. Revenue related to maintenance and service contracts is recognized ratably over the duration of the contracts. Effective with its adoption of Emerging Issues Task Force ("EITF") 00-21, "Multiple Deliverable Revenue Arrangements," when elements such as products and services or other elements are combined in a single arrangement, or in related arrangements with same customer, the Company allocates revenue to each element based on its relative fair value, provided that such element meets the criteria for treatment as a separate unit of accounting. The price charged when the element is sold separately generally determines fair value. In the absence of fair value for an undelivered element, the arrangement is accounted for as a single unit of accounting, resulting in a delay of revenue recognition for the delivered elements until the undelivered elements are fulfilled. 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. These contracts are accounted for under the provisions of Statement of Position ("SOP") 81-1, "Accounting for Performance of Construction-Type and Certain Production-Type Contracts," using the completed contract and percentage of completion method of accounting. Product development revenue for contracts recorded using the completed contract method is recognized when development is complete under the terms of the contract, and the customer has accepted the product. The direct cost, primarily labor, of product development contracts is deferred until the development revenue is recognized. Losses on contracts are accrued in the period that such losses are determined under the percentage of completion method. Under the percentage of completion method, revenue is recognized as work is performed, based on the relationship between actual costs incurred and total estimated costs at completion. Revenues are adjusted prospectively for revisions in estimated total contract costs when identified. Losses, if any, are recognized in full when identified. The Company has not leased any equipment to customers since liquidating its ISS-SA European operation in the fourth quarter of 2003. Prior to the fourth quarter of 2003, the Company, through its ISS-SA subsidiary, recognized revenue from leasing activities in accordance with Statement of Financial Accounting Standards ("SFAS") No. 13, "Accounting for Leases." Accordingly, leases that, transfer substantially all the benefits and risks of ownership are accounted for as sales-type leases. All other leases are accounted for as operating leases. Under the sales-type method, profit is recognized at lease inception by recording revenue and cost. Revenue consists of the present value of the future minimum lease payments discounted at the rate implicit in the lease. Cost consists of the equipment's book value. The present value of the estimated value of the equipment at lease termination (the residual value), which is generally not material, and the present value of the future minimum lease payments are recorded as assets. In each period, interest income is recognized as a percentage return on asset carrying values. The cost of equipment subject to operating leases is recorded as leased equipment and is depreciated on a 39

Integrated Surgical Systems, Inc. Notes to Consolidated Financial Statements straight-line basis over the estimated service life of the equipment. Operating lease revenue is recognized as earned over the term of the underlying lease. All such leasing activity was performed by, and recorded on the books of, ISS-SA. As a result, at December 31, 2003, the Company held no such leases. During the year ended December 31, 2004 and the year ended December 31, 2003, the Company recorded $0 and $238,000, respectively, in revenues from cancelable operating leases. Foreign Currency Translation The financial position and results of ISS-SA and ISS-BV are measured in Euros. Balance sheet accounts are translated into dollars at the year-end exchange rate and statement of operations amounts are translated at the average exchange rate for the period. The resulting translation adjustments are recorded in the other comprehensive income section of stockholders' deficit. The Company's foreign currency transactions are usually recorded and settled in the same foreign currency, without foreign exchange transaction gains or losses. Foreign exchange transaction gains or losses are, however, recognized when translating inter-company receivables and payables. Primarily due to the liquidation of ISS-SA and the closure of its European operations, the Company reversed its existing accumulated foreign exchange translation adjustment balance of $1,284,769 in December 2003. Research and Development Research and development costs are expensed as incurred. Grants received from third parties for research and development activities are recorded as reductions of research and development expense over the term of the agreement as the related activities are conducted. Shipping and Handling Costs Costs related to shipping and handling are included in costs of revenues for all periods presented. Certain Risks and Uncertainties The Company uses financial instruments that potentially subject it to concentrations of credit risk. Such instruments consist primarily of cash and accounts receivable. The Company's cash is invested in cash deposits, substantially all with one financial institution. The Company sells its products to companies in the healthcare industry, most of which are located in foreign countries. The Company requires a down payment when an order is received, with a progress payment upon shipment, and final payment upon completion of training and installation or customer acceptance. The Company believes that adequate provisions for uncollectable accounts receivable has been made in the accompanying consolidated financial statements. A significant portion of the Company's sales are to a limited number of customers located in foreign countries. Three major foreign customers of the Company accounted for 45%, 24% and 22% of the Company's revenue during the year ended December 31, 2004, and three major foreign customers accounted for 22%, 14% and 13% for the year ended December 31, 2003. At December 31, 2004, two foreign customers accounted for 98% of accounts receivable, and at December 31, 2003, two customers accounted for 100% of accounts receivable. 40

Integrated Surgical Systems, Inc. Notes to Consolidated Financial Statements Foreign revenue, substantially all from Western European countries, Japan, India and Korea was approximately $2,360,000 and $5,225,000 for the years ended December 31, 2004 and December 31, 2003, respectively. One of the key components of the ROBDOC system, a customized Robotic arm, has been manufactured by a Japanese manufacturer, Sankyo Seiki, per ISS specifications. The specifications, for this component, are the proprietary property of the Company and can not be used by anyone else to build or supply robot arms. The manufacturer has discontinued their medical robot business, and will not manufacture new robot arms for the Company. This situation does not create immediate risk as the Company has supplies in inventory to meet anticipated demand through December 31, 2005 and, the Company is redesigning the robot arm and is securing a new vendor for alternative vendor manufacture. Any significant delay in securing a new vendor for this component could have a material adverse effect on the financial condition, results of operations, or cash flow of the Company. Financial Statement Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash Cash includes cash deposited in bank accounts. Property and Equipment Property and equipment are stated at cost. Depreciation is calculated using the straight-line method over estimated useful lives of 3 to 5 years or the lease term, whichever is shorter. Inventory Inventory is recorded at the lower of cost (first-in, first-out method) or market and consists of materials and supplies used in the manufacture and service support of the Company's products, and deferred costs associated with certain of the Company's development contracts. Inventory consisted of the following at December 31, 2004: Raw materials $125,790 Work-in-process 219,669 Finished goods 94,181 Deferred product development contract costs 206,570 -------- $646,210 ======== 41

Integrated Surgical Systems, Inc. Notes to Consolidated Financial Statements Warranty The Company offers a one-year warranty for parts and labor on all ROBODOC systems commencing upon the completion of training and installation, except when the sales contract requires formal customer acceptance. In most cases, the Company's customers purchase a service contract, which includes warranty coverage (parts and labor), unspecified product maintenance updates, customer support services and various consumables required during surgical procedures. Revenue from service contracts is initially deferred and then recognized ratably over the term of the agreements. Service contracts can be renewed at the customers' option, annually thereafter. Where the Company's products are not covered by separate service agreements, the Company provides for the estimated cost of product warranties at the time revenue is recognized, based on historical results. 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 periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary. The Company has no recorded warranty liability for the periods ending December 31, 2004 and December 31, 2003, as all systems within the one-year warranty periods were covered by service contracts. Stock-Based Compensation As permitted under the provisions of SFAS No. 123 "Accounting for Stock-Based Compensation," the Company has elected to account for stock-based compensation using the intrinsic value method prescribed by Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to Employees." Under the intrinsic value method, compensation cost is the excess, if any, of the quoted market price or fair value of the stock at the grant date or other measurement date over the amount an employee must pay to acquire the stock. Pro forma information regarding net income (loss) and earnings (loss) per share is required by SFAS No. 123, which also requires that the information be determined as if the Company had accounted for the employee stock options granted subsequent to December 31, 1994 under the fair value method of that statement. The fair value for these options was estimated at the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions for 2004 and 2003, respectively: risk-free interest rates of 3.4% and 3.0%; dividend yield of 0%; volatility factors of the expected market price of the common stock of 101% and 107%; and an expected life of the option of 4 years. The weighted average grant date fair value of these options was $0.08 in 2004 and $0.03 in 2003. No options with option prices less than the fair market value of the Company's stock on the date of grant were granted to employees in 2004 or 2003. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility. Because the Company's employee stock options have characteristics significantly different from those of traded options and because changes in the subjective input assumptions can materially affect the fair value estimate, it is the Company's opinion, the existing models do not necessarily provide a reliable single measure of the fair value of the employee stock options. For purposes of pro forma disclosures, the estimated fair value of the options is amortized to expense over the vesting period. 42

Under this method, deferred income tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are scheduled to be in effect when the differences are expected to reverse. Recent Accounting Pronouncements In May 2003, FASB issued Statement of Financial Accounting Standards No. (SFAS No. 150), "Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity." SFAS No. 150 requires certain financial instruments that embody obligations of the issuer and have characteristics of both liabilities and equity to be classified as liabilities. Many of these instruments previously were classified as equity or temporary equity and, as such, SFAS No. 150 represents a significant change in practice in the accounting for a number of mandatorily redeemable equity instruments and certain equity derivatives that frequently are used in connection with share repurchase programs. SFAS No. 150 is effective for all financial instruments created or modified after May 31, 2003, and to other instruments at the beginning of the first interim period beginning after June 15, 2003. The adoption of SFAS No. 150 did not have a material impact on the Company's consolidated financial position, cash flows or results of operations. In November 2002, the EITF reached a consensus on Issue 00-21, "Multiple Deliverable Revenue Arrangements" (EITF 00-21). EITF 00-21 addresses how to account for arrangements that may involve the delivery or performance of multiple products, services, and/or rights to use assets. The consensus mandates how to identify whether goods or services, or both, are to be delivered separately in a bundled sales arrangement should be accounted for separately because they are "separate units of accounting." The guidance can affect the timing of revenue recognition for such arrangements, even though it does not change rules governing the timing or pattern of revenue recognition of individual items accounted for separately. The final consensus is applicable to agreements entered into in fiscal periods beginning after June 15, 2003, with early adoption permitted. Additionally, companies will be permitted 43

Integrated Surgical Systems, Inc. Notes to Consolidated Financial Statements to apply the consensus guidance to all existing arrangements as the cumulative effect of a change in accounting principle in accordance with APB Opinion No. 20, "Accounting Changes." The adoption of EITF 00-21 did not have a material impact on the Company's consolidated financial position, cash flows or results of operations. Note 4. Property and Equipment Property and equipment consists of the following at December 31, 2004: Computer hardware and purchased software $ 206,166 Machinery and equipment 242,210 ROBODOC and NeuroMate System equipment 687,082 Furniture and fixtures 85,997 Leasehold improvements 10,383 ---------- 1,231,838 Less accumulated depreciation 1,226,424 ---------- $ 5,414 ========== Note 5. Financing 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, at the investor's option, 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. 44

Integrated Surgical Systems, Inc. Notes to Consolidated Financial Statements 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 Annual Report on Form 10-KSB 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. Note 6. Note Payable The Company received a $143,403 interest-free loan in 1997 from ANVAR, a French agency established to aid research and development projects. The loan provided funding for the first phase of the development of NeuroMate applications for spinal surgery. Under the terms of the loan, 50% of the revenues generated from the sale or licensing of the related technology, prototype, or articles manufactured specifically for the research project, were to be paid to ANVAR in the subsequent year, up to the balance of the loan amount outstanding. No such revenues were recorded during the years ending December 31, 2004 and 2003. The loan also provided for the forgiveness of the loan under certain conditions, including a review by ANVAR. In August 2003, ANVAR completed a review of the loan balance and determined that the remaining balance of approximately $109,000 was forgiven. The Company has recorded the forgiveness of the loan in other income, net in August 2003. Note 7. Stockholders' Deficit Common Stock At December 31, 2004 the Company has reserved a total of 6,017,714 shares of common stock for future issuance pursuant to Series G Convertible Preferred Stock, warrants and options outstanding. The Company established an Employee Stock Purchase Plan ("ESPP") in 1998. The ESPP plan provides all eligible employees an opportunity to acquire an ownership interest in Integrated Surgical Systems, Inc. on a payroll deduction or other compensation basis at a 15% discount. The plan is intended to qualify as an employee stock purchase plan under Section 423 of the Internal Revenue Code. The plan covers an aggregate of 300,000 shares of the Company's common stock. At December 31, 2004, no offerings have been made to employees under the ESPP plan. 45

(4) Aggregate estimated fair value of $5,000, based on Black-Scholes option valuation model. (5) Aggregate estimated fair value of $18,000, based on Black-Scholes option valuation model Preferred Stock The Company's Certificates of Incorporation authorize 1,000,000 shares of undesignated, serial preferred stock. Preferred stock may be issued from time to time in one or more series. The Board of Directors is authorized to determine the rights, preferences, privileges, and restrictions granted to and imposed upon any wholly unissued series of preferred stock and designation of any such series without any further vote or action by the Company's stockholders. Convertible Preferred Stock The Company's convertible preferred stock is classified as mezzanine financing, outside of permanent equity, due to its liquidation rights upon a change in control, as this condition is not solely within the Company's control. Given the liquidation rights of the Company's convertible preferred stock, these securities have been accounted for as if they were redeemable preferred stock. As such, the redemption value of the convertible preferred stock has been its liquidation preference of $168,496, and the carrying value of the convertible preferred stock is adjusted to its redemption amount at each balance sheet date through corresponding debits and credits to accumulated deficit and convertible preferred stock respectively, up to the liquidation preference. 46

Integrated Surgical Systems, Inc. Notes to Consolidated Financial Statements Since September 1998, the Company has received aggregate net proceeds of $14,084,995 from the sale of eight series of convertible preferred stock. Information concerning these convertible preferred stock financing is set forth below: Shares Net Series Date of Sale Sold Proceeds -------------------------------------------------------------------- A September 10, 1998 3,520 $ 3,300,447 B March 26, 1999 1,000 916,918 C June 10, 1999 750 658,190 D June 30, 1999 2,000 1,861,549 E July 30, 1999 3,000 2,819,484 F February 8, 2000 2,000 1,850,861 G May 30, 2000 1,800 1,610,555 H August 17, 2000 1,200 1,066,991 Each series of convertible preferred stock has a stated value of $1,000 per share and is convertible into common stock at conversion prices equal to 80% or 85% of the lowest sale price of the common stock on its listed market over the five trading days preceding the date of conversion ("Beneficial Conversion Feature") subject to a maximum conversion price. The number of shares of common stock that may be acquired upon conversion is determined by dividing the stated value of the number of shares of convertible preferred stock to be converted by the conversion price. The value assigned to the Beneficial Conversion feature of each class of preferred stock was based upon the difference between the maximum conversion price and the quoted market price of the common stock on the date the convertible preferred stock was sold (the "Discount"). The Discount was accreted using the straight-line method over the conversion period. No series of convertible preferred stock entitles holders to dividends or voting rights, unless required by law or with respect to certain matters relating to a particular series of convertible preferred stock. During the year ended December 31, 2003, 82 shares of Series G convertible preferred stock were converted into 2,888,889 shares of common stock. At December 31, 2004 and 2003, 168 shares of Series G convertible preferred stock were outstanding. At December 31, 2004, the series G shares would have converted into a minimum of 103,371 shares of common stock based upon its maximum conversion price of $1.63. No other series of preferred stock were outstanding. The number of shares of common stock issued upon conversion and the average actual conversion price for each series of convertible preferred stock converted into shares of common stock through December 31, 2004 was as follows: 47

Options granted under the plans may be incentive stock options or non-incentive stock options and generally have a term of ten years from the date of grant. The exercise price of incentive stock options granted under the plans may not be less than 100% of the fair market value of the common stock on the date of the grant. The exercise price of non-statutory stock options granted under the plans may not be less than 85% of the fair market value of the common stock on the date of the grant. For a person who, at the time of the grant, owns stock representing 10% of the voting power of all classes of the Company's stock, the exercise price of the incentive stock options or the non-statutory stock options granted under the plans may not be less than 110% of the fair market value of the common stock on the date of the grant. Each plan is administered by the Company's board of directors, as the board of directors may be composed from time to time. Certain officers and directors may be deemed to be "affiliates" as that term is defined under the Securities Act. The common stock acquired under the Plans by an affiliate may be re-offered or resold only pursuant to an effective registration statement or pursuant to Rule 144 under the Securities Act or another exemption from the registration requirements of the Securities Act. The 1995 Stock Option Plan: The 1995 Plan was approved by the Company's board of directors on December 22, 1995. The purpose of the 1995 Plan is to attract, motivate and retain selected employees and other individuals providing services to us.

Integrated Surgical Systems, Inc. Notes to Consolidated Financial Statements Note 8. Income Taxes Deferred taxes result from temporary differences in the recognition of certain revenue and expense items for income tax and financial reporting purposes. The significant components of the Company's deferred taxes as of December 31, 2004 and 2003 are as follows: 2004 2003 ---------------------------- Deferred tax assets: Net operating loss carryover $19,249,000 $19,882,000 Research and development credit 2,301,000 2,212,000 Research and development 228,000 305,000 Accrued product retrofit costs -- -- Inventory 268,000 303,000 Depreciation 77,000 154,000 Stock compensation 289,000 289,000 Loss on investment 126,000 126,000 Deferred income 1,565,000 1,130,000 Other 199,000 227,000 ---------------------------- 24,302,000 24,628,000 Less valuation allowance 24,302,000 24,628,000 ---------------------------- Net deferred taxes $ -- $ -- ============================ The Company expects the carryforward amounts will not be used prior to the expiration of the carryforward periods. The principal reasons for the difference between the effective income tax rate and the federal statutory income tax rate as of December 31, 2004 and 2003 are as follows: 2004 2003 -------------------------- Federal benefit expected at statutory rates $ (189,129) $(1,136,670) Domestic net operating loss with no current benefit 187,539 5,019,945 Net effect of foreign operations -- (70,744) Other taxes 1,590 (3,814,892) Other non-deductible items -- 2,361 -------------------------- $ -- $ -- ========================== As a result of stock sales through December 31, 1995, a change of ownership (as defined in Section 382 of the Internal Revenue Code of 1986, as amended) has occurred. As a result of this change, the federal and state net operating loss carryforwards from these years will be subject to a total annual limitation in the amount of approximately $400,000. The Company had at December 31, 2004 a net operating loss carryover of approximately $42,055,000 for federal income tax purposes which expires between 2005 and 2023, a net operating loss carryforward of approximately $11,204,000 for state income tax purposes which expires between 2005 and 2013, and a net capital loss carryover for federal income tax purposes of $12,640,000 which will expire in 2008. 50

Integrated Surgical Systems, Inc. Notes to Consolidated Financial Statements The Company had at December 31, 2004 research and development credit carryovers of approximately $1,446,000 and $1,295,000 for federal and state income tax purposes, respectively. The Company paid $800 for income and franchise taxes during each of the two years ended December 31, 2004 and 2003. The valuation allowance decreased by $326,000 in 2004 and increased by $5,855,000 in 2003. Note 9. Net Loss Per Share Information At December 31, 2004, outstanding options to purchase 2,203,192 shares of common stock (with exercise prices ranging from $0.025 to $8.50), 2,606,479 outstanding warrants to purchase 2,606,479 shares of common stock (with exercise prices from $0.01 to $0.0625), and 6,017,714 shares of common stock issuable upon conversion of Series G Preferred Stock could potentially dilute basic earnings per share in the future and have not been included in the computation of diluted net loss per share because to do so would have been antidilutive for the periods presented. The exercise price and the ultimate number of shares of common stock issuable upon conversion of the warrants are subject to adjustments based upon the occurrence of certain future events. Note 10. Commitments The Company's executive offices and production facility are located in Davis, California. The Company occupies the facility in Davis under a lease that expires in June 2005, which is currently being renegotiated. During the third quarter of 2004, the Company renegotiated this lease to reduce the square footage from approximately 30,500 square feet to approximately 16,000 square feet, with a corresponding per month reduction in monthly rent expense from approximately $32,500 per month to approximately $18,000 per month. Prior to the renegotiations of the lease, the Company paid utilities and maintenance fees directly to the providers of these services. These utility and maintenance fees are now paid to the providers directly by the lessor and billed back to the Company, along with property taxes, on a pro-rated percentage based on the Company's percentage of occupancy. Future payments under the non-cancelable facility operating lease is approximately $90,000 for the year ending December 31, 2005. Aggregate rental expense under this lease and the Company's lease for ISS-SA's facility in France amounted to approximately $321,000 and $438,000 during the years ended December 31, 2004 and 2003, respectively. Effective October 1, 2003, the lease in France was terminated by the Tribunal and no further expenses were recorded. Note 11. 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 any remedy could be reached on mutually agreeable terms, if at all. Due to the inherent uncertainties of litigation, the Company would not be able to accurately predict their ultimate outcome. On December 17, 2004, the Company was served with a summons and complaint commenced in Yolo County (California) Superior Court, styled Bischoff, et al. vs. Integrated Surgical Systems, Inc. et al. The plaintiffs, in the litigation, 51

Integrated Surgical Systems, Inc. Notes to Consolidated Financial Statements all from Germany, allege that the Company's ROBODOC System is defective and dangerous, both in its manufacture and design and, as a result of such defect and dangerous condition, the plaintiff, all of whom were subject to medical treatment utilized the ROBODOC System, sustained injury. The plaintiffs are seeking class status for this matter. The Company believes the plaintiff's allegations are without merit. The Company intends to conduct a vigorous defense against the allegations contained in the complaint. However, the Company did not have any product liability insurance from June 2004 through March 3, 2005, due to its financial inability to pay the requisite insured premiums. Effective March 4, 2005 the Company secured a new product liability insurance policy in the amount of $2 million per occurrence and $2 million in aggregate. This case is at its incipient stages. The Company has retained competent counsel to represent it in this matter. The amount of damages, if any, are indeterminable at this juncture. Defending against a product liability action can be expensive and time consuming to management personnel. The Company currently does not have the funds, which may be necessary to defend against the plaintiffs' allegations. The failure to properly defend the Company against the allegations could result in a material judgement against the Company, which could adversely affect our financial condition, results of operations and cash flow. The Company may also currently not have the funds necessary to satisfy any judgement rendered against it. The Company's failure to successfully defend against the allegations could result in our seeking protection under the United States Bankruptcy Code. Such action could have a material adverse effect on the market price of the Company's common stock, business, financial condition, cash flow and results of operations. In accordance with SFAS No. 5. "Accounting for Contingencies," the Company has reviewed the facts related to the liquidation of its investment in ISS-SA and closure of its European operations (see Note 1) and has determined that no provision for loss is required related to this action. Were a claim to be filed the Company would not be able to accurately predict its ultimate outcome. Note 12. Related Party Transactions At December 31, 2004, the Company had an aggregate amount due to executive officers of approximately $1,013,000. These amounts due are in the form of an interest bearing advance, deferred salaries and unreimbursed travel expenses. Of such amounts, $460,000 and $276,000 are included in accrued payroll and related expense and accounts payable and accrued liabilities, respectively, and are due to Ramesh C. Trivedi, president and chief executive officer of the Company; $141,000 and $27,000 are included in accrued payroll and related expense and accounts payable, respectively, and are due to Leland Witherspoon, vice president of engineering of the Company; and $109,000 is included in accrued payroll and related expense and is due to Charles J. Novak, chief financial officer of the Company. At December 31, 2004, the Company had accrued payroll and accrued payroll taxes of $479,000 for all other employees. Note 13. Restatement of Unaudited Interim Financial Information In conjunction with the audit of its financial statements for the year ended December 31, 2004, the Company determined that it had overstated accounts receivable and unearned income as of September 30, 2004 due to prematurely or incorrectly recording certain service contracts with its customers. Accounts receivable and unearned income as of September 30, 2004 were overstated by $287,897 and $253,933, respectively. In the third quarter of 2004, net revenue 52

Integrated Surgical Systems, Inc. Notes to Consolidated Financial Statements was overstated by $33,964 and net loss understated by a similar amount, as a result of the amortization related to these service contracts. There was no impact on the reported amount of basic or diluted net loss per common share as a result of the correction. A summary of the Company's interim financial information as of, and for the three month period ended, September 30, 2004, as reported and as restated is provided below: - ---------------------------------------------------------------------------- As Reported As Restated - ---------------------------------------------------------------------------- Accounts Receivable $ 329,948 $ 42,051 - ---------------------------------------------------------------------------- Unearned Income $ 2,714,991 $ 2,461,058 - ---------------------------------------------------------------------------- Net Revenue $ 139,140 $ 105,176 - ---------------------------------------------------------------------------- Net Loss $ (332,861) $ (366,825) - ---------------------------------------------------------------------------- Basis and Diluted Net Loss Per Common Share $ (.01) $ (.01) - ---------------------------------------------------------------------------- 53
