CT refers to a diagnostic imaging device in which cross-sectional (tomographic) images of a patient's anatomy are acquired from multiple intensity readings taken as an x-ray source rotates around the patient. Ultrafast CT technology is more than 20 times faster than conventional computed tomography, enabling users to perform certain tests involving organs in motion (e.g. the heart) that no other medical imaging equipment is able to perform. For over a decade, the scanner has been used in large and mid-sized hospitals and free standing imaging clinics. The Company also provides service, parts, and maintenance to hospitals and clinics that operate its scanners. The technological advantage provided by high-speed tomography now provides Imatron the opportunity to develop a new and additional market, by performing simple, low cost, non-invasive screening to detect the earliest signs of heart disease by means of the Coronary Artery Scan ("CAS"). This vast new market involves activity in both diagnostic services and equipment manufacturing. The Company is also engaged in the related businesses of performing research and development for itself and others in the field of CT devices and of licensing its patents and know-how in the field of imaging sciences. Imatron was incorporated in New Jersey in February, 1983. Its executive offices are located at 389 Oyster Point Boulevard, South San Francisco, California 94080, and its telephone number is (415) 583-9964. In 1993, Imatron organized HeartScan Imaging, Inc. as a wholly-owned subsidiary to develop and operate a network of company-owned coronary artery disease risk assessment centers in cooperation and conjunction with the established medical (primarily cardiology) community in specific metropolitan areas. In that same year, HeartScan opened a test facility adjacent to Imatron's headquarters. In July, 1995, it opened its first coronary artery disease risk assessment center in Seattle, Washington. In January, 1996, it opened its second facility in Houston, Texas. It plans to open similar facilities in Washington, D.C. and Pittsburgh, Pennsylvania, in July, 1996. HeartScan's centers deliver the CAS diagnostic test together with other risk factor tests in a manner consistent with established channels of patient referral, as well as with the new channels of patient referral being created by health care reform and the growth of managed-care systems. A significant component of HeartScan's approach is to offer the CAS procedure and a full battery of coronary artery disease risk assessment testing to consumers without necessarily requiring a physician's referral, an approach designed to result in more rapid acceptance of the test and a shorter return on the investment cycle. This is achieved by means of two broad and mutually supportive approaches - increasing the number of coronary artery disease risk assessment centers in operation, which in turn, both directly and indirectly, increases the demand 4 for Imatron's C-150/Evolution scanner currently in distribution. HeartScan management believes that the market for coronary artery disease risk assessment centers is very large and that HeartScan's comprehensive heart disease screening approach is both revolutionary and highly effective. HeartScan Imaging, Inc. was incorporated in Delaware in April, 1993. Its executive offices are currently co-located with those of Imatron Inc. at 389 Oyster Point Boulevard, South San Francisco, California 94080, and its telephone number is (415) 583-9964. RISK FACTORS The securities offered hereby are speculative and involve a high degree of risk. Prospective investors may lose all or a part of their investment. Consequently, the following factors, in addition to the other information contained in this Prospectus, should be considered carefully in evaluating the Company and its business before purchasing the securities offered hereby: Short Operating History. Imatron was incorporated in February, 1983 and in April, 1983 became the successor to Imatron Associates, a limited partnership established in February, 1981. Imatron operated as a development-stage company until the fourth quarter of 1984, at which time it recognized its initial sale of an ULTRAFAST CT(R) scanner. Imatron incurred losses each quarter from inception in February, 1981 through December 31, 1990. Its first recorded profitable year was the year ended December 31, 1991 during which a $4,000,000 payment for the licensing of technology to Siemens Corporation was received. The Company incurred net losses of $2,871,000 and $6,523,000 in the years ended December 31, 1993 and 1992, respectively. 1994 was the Company's first year of profit from operations. In 1995, the Company incurred a net loss of $2,449,000. There is no assurance that Imatron can return to profitable operations in the future. In the past, Imatron has funded its losses primarily through the sale of securities in two public offerings and a number of private placements, through the exercise of options and warrants, through the 1991 license for medical uses of its electron-beam technology to Siemens Corporation, and through revolving lines of credit. In 1995, the Company raised $9,882,000 (net of offering costs) in two offerings of Common Stock to certain institutional investors. The Company has an accumulated deficit of $57,557,000. Management believes that cash, cash equivalents and short-term investments existing at December 31, 1995 and the estimated proceeds from ongoing sales of products and services in 1996 will provide the Company with sufficient cash for operating activities and capital requirements through December 31, 1996. Need for Additional Financing. To satisfy the Company's future capital and operating requirements, profitable operations or additional public or private financing will be required. If future public or private financing is required by the Company, holders of the Company's securities may experience dilution. If such financing cannot be obtained, the Company may seek to sell or license additional portions of its technology, to sell some or all of its other assets or 5 to merge with another company. In addition, HSI will need substantial additional financing to fund its plan to own and operate CAS clinics. To date HSI has been unable to raise such funds and has relied upon the Company for financing. In the event HSI cannot raise such funds it will have to curtail its expansion activities. Material Dependence Upon Key Personnel. The Company has been and will continue to be materially dependent upon the technical expertise of its engineering management personnel. The loss of a significant number of such personnel would have a materially adverse effect upon the Company's business and future prospects. The Company does not maintain key-man life insurance. High Cost of Scanner. The distributor list price of Imatron's ULTRAFAST CT scanner is significantly higher than that of commercially available conventional CT scanners and higher than the price of "top-of-the-line" scanners. Such pricing may limit the market for Imatron's product. Potential customers' budgetary limitations, including those imposed by government regulation, may often compel the purchase of lower cost, conventional CT scanners. Limited Clinical Demonstration of Certain Advantages of Company's Scanner. The Company's scanners have been used in a clinical environment on humans since April, 1983. Clinical use of the C-100 XL scanner model began in February 1989 and twenty-seven C-150 scanners are currently installed in a clinical setting. The Company believes that market acceptance of the ULTRAFAST CT scanner continues to depend in substantial part upon the clinical demonstration of certain asserted technological advantages and diagnostic capabilities. There is no assurance that these advantages will result in the development of a significant market for the ULTRAFAST CT that will allow the Company to operate profitably. Product Liability Risks. As a manufacturer and marketer of medical diagnostic equipment, the Company is subject to potential product liability claims. For example, the exposure of normal human tissue to x-rays, which is inherent in the use of CT scanners for diagnostic imaging, may result in potential injury to patients, thereby subjecting the Company to possible liability claims. The Company presently maintains primary and excess product liability insurance with aggregate limits of $5,000,000 per occurrence. No assurance can be given that the Company's product liability insurance coverage will continue to be available or, if available, that it can be obtained in sufficient amounts or at reasonable cost or that it will prove sufficient to pay any claims that may arise. Reliance On Patents And Proprietary Technology. Imatron relies heavily on proprietary technology which it attempts to protect through patents and trade secrets. In February 1981, the Company was granted the exclusive use for five years and non-exclusive use thereafter of certain technology and a patent pending owned by the University of California (UC) under the terms of a license agreement between UC and Emersub, a wholly-owned subsidiary of a former principal shareholder of the Company, and a sublicense agreement between Emersub and Imatron Associates (the predecessor to the Company), respectively. In 6 June 1986, the license and sublicense agreements were amended to extend the Company's exclusive use of the technology through the remaining 9-year life of the patent in exchange for modified minimum annual royalty payments. Under the terms of Emersub's license with UC, Emersub was obligated to make certain additional payments in connection with the license. In October 1990, pursuant to subsequent amendments of the license and sublicense agreements, the Company issued an aggregate of 132,813 shares of Series A Preferred Stock to UC and Emersub in satisfaction of this obligation. The University of California converted their 125,000 Series A Preferred Stock into 625,000 common stock shares in 1993. Emersub converted their 7,813 Series A Preferred Stock into 39,065 common stock shares in September 1995. In addition, the sublicense agreement, as amended, requires the Company to pay annual royalties to Emersub equal to 2.125% of net sales of certain of the Company's products. The Company's Chairman of the Board, Dr. Douglas P. Boyd, receives 6% of all of the royalties paid by Emersub to UC. Loss by Imatron of its rights under the patent as a result of termination of its sublicense from Emersub, or the underlying license, could have a material adverse effect upon Imatron's business and future prospects. There are no present disputes with either UC or Emersub. Development of portions of the technology covered by the UC patent and sublicensed to Imatron has been funded in substantial part through research financing made available to UC by the National Institutes of Health. As a result of such financing, it is possible that the U. S. Government may assert certain claims in such UC patents, including the right to a royalty-free license for governmental use. In addition, Imatron holds twenty-seven U.S. Patents of its own (each with a remaining life in excess of 3 years) and has filed three U.S. patent applications covering various integral components of the scanner including, among others, its electron beam assembly and its x-ray detector and has filed applications corresponding to several of these patents and applications in various European Patent Convention countries, Canada and Japan. There can be no assurance that any such applications will result in the issuance of a patent to the Company. Imatron's patents and patent applications have not been tested in litigation and no assurance can be given that patent protection will be upheld or will be as extensive as claimed. Furthermore, no assurance can be given as to the Company's ability to finance litigation against parties which may infringe upon such patents or parties which may claim that the Company's scanner infringes upon their patents. However, the agreement signed by the Company and Siemens Corporation in March 1991 allows Siemens Corporation to enter litigation in favor of Imatron. On March 31, 1995, the Company and Siemens Corporation ("Siemens") entered into an agreement (the "Memorandum of Understanding") relating in part to certain of the Company's patents. Pursuant to the agreement, the Company transferred to Siemens five patents, two of which cover features of the Company's C-150 scanner, in consideration of the cancellation by Siemens of a $4 million term loan to the Company. As part of the agreement Siemens granted to the Company a non-exclusive, irrevocable, perpetual license to the five patents. The license 7 is subject to a royalty of $20,000 for each new C-150 unit produced by the Company beginning with the twenty-first C-150 unit produced in any year. Siemens has recently asserted a claim against the Company regarding the lapse of certain foreign registrations of one of the patents assigned to Siemens by the Company in connection with the March 31, 1995 agreement between the companies. The technology involved in the patent is not used presently in any of the Company's products. The Company believes that it can provide a new patent to Siemens to replace the lapsed patent. While the resolution of the claim is not expected to have a material effect on the Company's financial position it could however, have a material effect on the results of operations of a particular future period if resolved unfavorably. In the event some or all of the Company's patent applications are denied and/or some or all of its patents held invalid, the Company would be prevented from precluding its competitors from using the protected technology set forth in such patent applications or patents. Because the Company's products involve confidential proprietary technology and know-how, the Company does not believe such a loss of patent rights would have a material adverse effect upon the Company. The Company also believes that many of its proprietary technologies are better protected as trade secrets or copyrights than by patents. Moreover, although protection of the Company's existing proprietary technologies is important, other factors such as product development, customer support and marketing ability are equally important to the development of the Company's business. Limited or Single Sources of Supply. The Company manufactures its scanners at its South San Francisco, California facility. To date the typical manufacturing cycle has required six months based on inventory. Lead time can be significant between authorization of manufacturing to delivery of a scanner. Many of the components and sub-assemblies used in the scanner have been developed and designed by Imatron to its custom specifications and are obtainable from limited or single sources of supply. In view of the customized nature of many of these components and sub-assemblies, there may be extended delays between their order and deliver. Delays in such delivery could adversely affect Imatron's present and future production schedules. The Company has made and continues to make inventory investments to acquire long lead time components and sub-assemblies to minimize the impact of such delays. In recent years, the Company has developed alternative sources for many of its scanner subcomponents and continues its programs to qualify vendors for the remaining critical parts. Also, certain vendors currently require cash-on-delivery or prepay payment terms. There can be no assurance that such actions will not adversely affect the Company's production schedule and its ability to deliver products in a timely manner. As a result of certain vendors 8 currently requiring cash-on-delivery or prepay terms, the Company must maintain higher levels of cash and other sources of credit to fund material purchases than otherwise would be required. Volatility of Stock Price. The market prices for securities of advanced technology companies have historically been highly volatile, including the market price of shares of the Company's Common Stock. Future announcements by the Company or its competitors, including announcements concerning technological innovations or new commercial products, results of clinical testing, changes in government regulations, regulatory actions, health care reform, proprietary rights, litigation and public concerns as to the safety of the Company's or its collaborators' products, as well as period-to-period variances in financial results could cause the market price of the Common Stock to fluctuate substantially. In addition, the stock market has experienced extreme price and volume fluctuations that have particularly affected the market price for many advanced technology companies that have often been unrelated to the operating performance of these companies. These broad market fluctuations may adversely affect the market price of the Common Stock. Food And Drug Administration And Other Governmental Regulation. Amendments to the Federal Food, Drug, and Cosmetic Act ("Amendments") enacted in 1976, and regulations issued or authorized thereunder, provide for regulation by the Federal Food and Drug Administration ("FDA") of the marketing, manufacture, labeling, packaging, sale and distribution of "medical devices," including the Company's scanner. Among these regulations are requirements that medical device manufacturers register their manufacturing facilities with the FDA, list devices manufactured by them file various reports and comply with specified Good Manufacturing Practice ("GMP") regulations. The FDA enforces additional regulations regarding the safety of equipment utilizing x-rays, including CT scanners. Various states also impose similar regulations. The Amendments also impose certain requirements which must be met prior to the initial marketing of medical devices introduced into commerce after May 28, 1976. Other requirements imposed on medical device manufacturers include a pre-market notification process commonly known as the 510(k) application to market a new or modified medical device. Additionally, and specifically if required by the FDA, a pre-market approval ("PMA") may be required. This process is potentially expensive and time consuming and must be completed prior to marketing a new medical device. The Company has received appropriate clearances from the FDA to market both the C-100 and C-150 ULTRAFAST CT scanner. The Company believes that it is presently in substantial compliance with the GMP requirements and other regulatory issues promulgated by the FDA. The FDA also regulates the safety and efficacy of radiological devices. Although the Company believes it is in compliance with all applicable radiological health regulations promulgated by the FDA, there can be no assurance that the ULTRAFAST CT scanner will continue to comply with all such standards and regulations that may be promulgated. In any event, compliance with all such requirements can be costly and time consuming, with a resultant 9 materially adverse effect upon the development of the Company's business and its future profitability. FDA clearance to market does not guarantee or imply reimbursement by third-party payers such as Medicare, Medicaid, Blue Cross/Blue Shield or private health insurers. Medicare and Medicaid reimburse for procedures that are generally accepted or that have been proven safe and effective. The Health Care Financing Administration ("HCFA"), which oversees Medicare and Medicaid payment policies, will not authorize payment for procedures which are considered to be experimental. HCFA has determined that diagnostic examinations of the head and other parts of the body performed by CT scanners are covered if the contractor who administers the local Medicare program finds that medical and scientific literature and opinion support the effective use of a scan for the particular condition. The Federal government and certain states have enacted cost-containment measures such as the establishment of maximum fee standards in an attempt to limit the extent and cost of governmental reimbursement of allowable medical expenses under Medicare, Medicaid and similar governmental programs. A number of states have adopted or are considering the adoption of similar measures. Such limitations have led to a reduction in, and may further limit funds available for, the purchase of diagnostic equipment such as the Company's scanner and in the number of diagnostic imaging procedures performed in hospitals and other medical institutions such as imaging clinics. Certain states have adopted requirements that hospitals and other health care facilities, such as imaging clinics, obtain a Certificate of Need ("CON") for major capital expenditures, in the absence of which they will be denied reimbursement for services and funding relating to such capital expenditures. A number of states have enacted more stringent CON legislation such as requiring private physicians to obtain a CON for any CT scanner, regardless of cost. There can be no assurance that Imatron's potential customers will be able to secure CONs or will be willing to pursue the application procedure. The Company's primary customers operate in the healthcare industry. The health care industry is highly regulated. Both existing and future governmental regulations could adversely impact the market for the Company's ULTRAFAST CT scanner and the Company's business. The Company's operations are also subject to regulation by other federal, state and local governmental entities empowered to enforce pertinent statutes and regulations, such as those enforced by the Occupational Safety and Health Agency and the Environmental Protection Agency. In some cases, state or local regulations may be stricter than regulations imposed by the federal government. The Company was most recently inspected by the State of California Department of Occupational Safety and Health Administration in November, 1993. Minor violations were issued by Cal/OSHA and were immediately corrected by the Company. The subsequent follow up inspection in December by the same regulatory body yielded satisfactory results without the issuance of further notice of violation. The Company believes that it is in substantial compliance with California regulations applicable to its business. 10 Competition. In the non-cardiac imaging applications market (composed principally of hospital radiology departments), the Company's principal competition is from current manufacturers of conventional CT scanners, including General Electric Company, Siemens Corporation, Elscint, Picker International, Inc., Philips Medical Systems, and Toshiba Medical Corporation. Non-invasive diagnostic imaging techniques such as ultrasound, radioisotope imaging, digital subtraction angiography and magnetic resonance imaging are also partially competitive with the Company's scanners, particularly in the cardiac imaging market. Each of the companies named above markets equipment using one or more of these techniques. All of these companies have greater financial resources and larger and more established staffs than those of the Company and their products are in most cases substantially less expensive than the ULTRAFAST CT scanner. The Company believes that to compete successfully against these competitors, it must demonstrate that the ULTRAFAST CT scanner is both an acceptable substitute for conventional CT scanners in scanning areas of the body where motion is not a limitation and a valuable cardiac diagnostic tool capable of producing useful images of the heart. Although the Company believes that the ULTRAFAST CT can produce images of a quality and resolution as good as or superior to images produced by state-of-the-art conventional CT scanners, it lacks certain features that many competing premium scanners offer. These include lack of a high-resolution mode for imaging the temporal bones and inner ear and lower functionality in software used for automatically positioning the patient. There is no certainty that potential purchasers of the Company's scanner will accept it without such features. Also, the Company believes that customers and potential customers expect a continuing development effort to improve the functionality and features of the scanner. The Company continually seeks to develop product enhancements and improve product reliability. Imatron's future success may depend on its ability to complete certain product enhancement and product reliability projects currently in progress, as well as on its continued ability to develop new products or product enhancements in response to new products that may be introduced by other companies. There can be no assurance that Imatron will be able to continue to improve product reliability or introduce new product models or product enhancements as required to remain competitive. Other factors, in addition to those described above, that a potential purchaser would consider in the decision to replace a conventional CT scanner with an ULTRAFAST CT scanner include purchase price, patient throughput capacity, anticipated operating expenses, estimated useful life and post-sale customer service and support. The Company believes that its scanner and/or the Company is competitive with respect to each of these factors. Reliance on Distributors. A substantial portion of the Company's sales of its scanners is done through distributors. There is no assurance that the Company's distributors will actually meet their contractual minimums on a timely basis. Failure by the distributors to meet their obligations could adversely affect the Company. 11 No Dividends on Preferred and Common Stock. The Company has not paid any dividends on its Preferred or Common Stock since inception. Even if its future operations result in revenues and/or profitability, as to which there can be no assurance, there is no present anticipation that dividends will be paid. Rather, the Company expects that any future earnings will be applied toward the further development of the Company's business. USE OF PROCEEDS The Company will not receive any part of the proceeds from the sale of the Shares by the Selling Shareholders. As described under "Selling Shareholders", a portion of the Shares will be acquired by the Selling Shareholders upon exercise of the Warrants. Upon the exercise of a Warrant, the Company will receive the applicable exercise price per share from the Selling Shareholder. The Company will use such proceeds, if any, to increase working capital.

Undertakings. A. Rule 415 Offering. The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) To include any Prospectus required by Section 10(a)(3) of the Securities Act; (ii) To reflect in the Prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in the Registration Statement; Provided, however, that paragraphs (A)(1)(i) and (A)(1)(ii) do not apply if the Registration Statement is on Form S-3, or Form S-8, and the information required or to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (4) To deliver or cause to be delivered with the Prospectus, to each person to whom the Prospectus is sent or given, the latest annual report to security holders that is incorporated by reference in the Prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Exchange Act; and, where interim financial information required to be presented by Article 3 of Regulation S-X are not set forth in the Prospectus, to deliver, or cause to be delivered to each person to whom the Prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the Prospectus to provide such interim financial information. 19 B. Filings Incorporating Subsequent Exchange Act Documents By Reference. The Company hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Company's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in the Registration Statement shall be deemed to be a new Registration Statement relating to the securities offering therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. C. Acceleration of Effectiveness. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing provisions, or otherwise, the Company has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act, and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Company of expenses incurred or paid by a director, officer or controlling person of the Company in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Company will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. 20 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of South San Francisco, State of California, on June 15, 1996.

Each Purchaser will cause any proposed purchaser, assignee, transferee, or pledgee of the Shares to agree to take and hold such securities subject to the provisions and upon the conditions specified in this Agreement.

Until the sale or transfer of the Shares by the Purchasers shall be subject to an effective registration under Securities Act, each certificate representing the Shares and any other securities issued in respect of such securities upon any stock split, stock dividend, recapitalization, merger, consolidation or similar event shall (unless otherwise permitted by the provisions of Section 7 below) be stamped or otherwise imprinted with the following legends (in addition to any legend required under applicable state securities laws): "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AND SUBJECT TO CERTAIN EXCEPTIONS, MAY NOT BE SOLD IN THE UNITED STATES OR TO U.S. PERSONS. ANY SALE, TRANSFER, PLEDGE OR OTHER DISPOSITION THEREOF IN THE UNITED STATES OR TO U.S. PERSONS MAY BE MADE ONLY (i) IN A REGISTRATION UNDER SAID ACT OR (ii) IF AN EXEMPTION FROM REGISTRATION UNDER SAID ACT IS AVAILABLE AND THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL TO THAT EFFECT REASONABLY SATISFACTORY TO IT." Each Purchaser consents to the Company making a notation on its records and giving instructions to any transfer agent of the Shares in order to implement the restrictions on transfer established in this Agreement. As used hereinafter the term "Restricted Securities" shall mean the securities of the Company required to bear the legend set forth in this section. (c) Notice of Proposed Transfers. The holder of each certificate representing Restricted Securities by acceptance thereof agrees to comply in all respects with the provisions of this Section 4. Prior to any proposed sale, assignment, transfer or pledge of any Restricted Securities, unless there is in effect a registration statement under the Securities Act covering the proposed transfer, the holder thereof shall give written notice to the issuer thereof of such holder's intention to effect such transfer, sale, assignment or pledge. Each such notice shall describe the manner and circumstances of the proposed transfer, sale, assignment or pledge in sufficient detail, and shall, if reasonably requested by the issuer, be accompanied, at such holder's expense by either (i) written opinion of legal counsel who shall be, and whose legal opinion shall be, reasonably satisfactory to the Company addressed to the Company, to the effect that the proposed transfer of the Restricted Securities may be effected without registration under the Securities Act, or (ii) a "no action" letter from the Securities and Exchange Commission (the "Commission") to the effect that the transfer of such securities without registration will not result in a recommendation by the staff of the Commission that action be taken with respect thereto, 29 whereupon the holder of such Restricted Securities shall be entitled to transfer such Restricted securities in accordance with the terms of the notice delivered by the holder to the Company. 6. Covenants of the Company. The Company covenants and agrees with the Purchaser to refrain from engaging, and to insure that none of its affiliates will engage, in any Directed Selling Efforts with respect to the Shares or any distribution, as that term is used in the definition of Distributor, with respect to the shares. 7. Registration. (a) Certain Definitions.

(ii) "Holder" shall mean any Purchaser holding Registrable Securities and any person holding Registrable Securities to whom the rights under this Agreement have been transferred in compliance with Section 7.3 hereof.

IMATRON INC. COMMON STOCK PURCHASE WARRANT This Warrant Expires May 24, 1999 Warrant No. 96-A Shares: 2,000,000 THIS CERTIFIES that, subject to the terms and conditions herein set forth, JOSE MARIA SALEMA GARCAO (the "Holder") is entitled to purchase from Imatron Inc., a New Jersey corporation (the "Company"), at any time or from time to time during the Exercise Period (as hereinafter defined) the number of shares of fully paid and non-assessable shares of Common Stock of the Company (the "Shares") as provided herein upon surrender hereof at the principal office of the Company, and, at the election of the holder hereof, upon payment of the purchase price at said office in cash or by cashier's check or by the wire transfer of funds in a dollar amount equal to the purchase price of the Shares for which the consideration is being given. This Warrant shall be exercisable for that number of Shares as set forth above, in minimum units of 100,000 shares. 1. Purchase Price. Subject to adjustment as hereinafter provided, the purchase price of one share of Common Stock (or such securities as may be substituted for one share of Common Stock pursuant to the provisions hereinafter set forth) (the "Warrant Price") shall be the following: 1,200,000 shares $3.25 800,000 shares $3.75 39 2. Adjustment of Warrant Price and Number of Shares. The number and kind of securities issuable upon the exercise of this Warrant shall be subject to adjustment from time to time upon the happening of certain events as follows: (a) Adjustment for Dividends in Stock. In case at any time or from time to time on or after the date hereof the holders of the Common Stock of the Company (or any shares of stock or other securities at the time receivable upon the exercise of this Warrant) shall have received, or, on or after the record date fixed for the determination of eligible stockholders, shall have become entitled to receive, without payment therefor, other or additional stock of the Company by way of dividend (other than as provided for in Paragraph 2(b) below), then and in each such case, the holder of this Warrant shall, upon the exercise hereof, be entitled to receive, in addition to the number of shares of Common Stock receivable thereupon, and without payment of any additional consideration therefor, the amount of such other or additional stock of the Company which such holder would hold on the date of such exercise had it been the holder of record of such Common Stock on the date hereof and had thereafter, during the period from the date hereof to and including the date of such exercise, retained such shares called for during such period by this Paragraph 2. (b) Adjustment for Changes in Common Stock. In the event of changes in the outstanding Common Stock of the Company by reason of split-ups, recapitalizations, reclassifications, mergers, consolidations, combinations or exchanges of shares, separations, reorganizations, liquidations, or the like, the number and class of shares available under the Warrant in the aggregate and the Warrant Price shall be correspondingly adjusted by the Board of Directors of the Company. The adjustment shall be such as will give the holder of the Warrant on exercise for the same aggregate Warrant Price the total number, class, and kind of shares as he would have owned had the Warrant been exercised prior to the event and had he continued to hold such shares until after the event requiring adjustment. 3. No Fractional Shares. No fractional shares of Common Stock will be issued in connection with any subscription hereunder. In lieu of any fractional shares which would otherwise be issuable, the Company shall pay cash equal to the product of such fraction multiplied by the fair market value of one share of Common Stock on the date of exercise, as determined by the fair market value of one share of the Company's Common Stock on the date of exercise as determined in good faith by the Company's Board of Directors. 4. No Stockholder Rights. This Warrant shall not entitle its holder to any of the rights of a stockholder of the Company prior to exercise thereof. 5. Reservation of Stock. The Company covenants that during the period this Warrant is exercisable, the Company will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of Common Stock upon the exercise of this Warrant. The Company agrees that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing stock certificates to 40 execute and issue the necessary certificates for shares of Common Stock upon the exercise of this Warrant. 6. Exercise of Warrant. This Warrant may be exercised by the registered holder or its registered assigns, in whole or in part and in minimum units of 10,000 shares, by the surrender of this Warrant at the principal office of the Company, together with the form of subscription hereof duly executed, accompanied by payment in full of the amount of the Warrant Price in the form described in this Warrant. Upon partial exercise hereof, a new warrant or warrants containing the same date and provisions as this Warrant shall be issued by the Company to the registered holder for the number of shares of Common Stock with respect to which this Warrant shall not have been exercised. A Warrant shall be deemed to have been exercised immediately prior to the close of business on the date of its surrender for exercise as provided above, and the person entitled to receive the shares of Common Stock issuable upon such exercise shall be treated for all purposes as the holder of such shares of record as of the close of business on such date. As promptly as practicable on or after such date, the Company shall issue and deliver to the person or persons entitled to receive the same, a certificate or certificates for the number of full shares of Common Stock issuable upon such exercise, together with cash in lieu of any fraction of a share as provided above. 7. Certificate of Adjustment. Whenever the Warrant Price is adjusted as herein provided, the Company shall promptly deliver to the record holder of this Warrant a certificate of an officer of the Company setting forth the relevant Warrant Price or number of shares after such adjustment and setting forth a brief statement of the facts requiring such adjustment. 8. Compliance With Securities Act. The holder of this Warrant, by acceptance hereof, agrees that this Warrant and the shares of Common Stock to be issued upon exercise hereof (or shares of any security into which such Common Stock may be converted) are being acquired for investment and that the holder will not offer, sell, or otherwise dispose of this Warrant and any shares of Common Stock to be issued upon exercise hereof (or shares of any security into which such Common Stock may be converted) except under circumstances which will not result in a violation of the Securities Act of 1933, as amended (the "Securities Act"). Upon exercise of this Warrant, the holder hereof shall, if requested by the Company, confirm in writing its investment purpose and acceptance of the restrictions on transfer of the shares of Common Stock. 9. Subdivision of Warrant. At the request of the holder of this Warrant in connection with a transfer or exercise of a portion of the Warrant, upon surrender of such Warrant for such purpose to the Company, the Company at its expense (except for any transfer tax payable) will issue and exchange therefor warrants of like tenor and date representing in the aggregate the right to purchase such number of shares of such Common Stock as shall be designated by such holder at the time of such surrender; provided, however, that the Company's obligations to subdivide securities under this section shall be subject to and conditioned upon the compliance of any such subdivision with applicable state securities laws and with the Securities Act. 41 10. Loss, Theft, Destruction, or Mutilation of Warrant. Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction, or mutilation of this Warrant, and in case of loss, theft, or destruction, of indemnity or security reasonably satisfactory to it, and upon reimbursement to the Company of all reasonable expenses incidental thereto, and upon surrender and cancellation of this Warrant, if mutilated, the Company will make and deliver a new Warrant of like tenor and dates as of such cancellation, in lieu of this Warrant. 11. Miscellaneous. This Warrant shall be governed by the laws of the State of California.
