THE COMPANY

CardioVascular Dynamics, Inc. ("CVD" or the "Company") designs, develops, manufactures and markets catheters used to treat certain vascular diseases. The Company's catheters are used in conjunction with angioplasty and other interventional procedures such as vascular stenting and drug delivery. The Company's proprietary FOCAL and Multiple Microporous Membrane ("M3") technologies enable physicians to deliver therapeutic radial force, stents, drugs or contrast media accurately and effectively to the treatment site, and also allow the perfusion of blood during an interventional procedure. The Company believes that the combination of these technologies on a multiple-purpose catheter enables physicians to effectively perform challenging interventional procedures, resulting in improved treatment outcomes and lower costs. The Company has five issued and four allowed U.S. patents covering certain aspects of its catheter technologies. Since commencing commercial sales in 1994, the Company has sold more than 12,000 catheters.

Cardiovascular disease, the leading cause of death in the United States, is caused principally by atherosclerosis. Atherosclerosis is a progressive and degenerative vascular disease in which cholesterol and other fatty materials are deposited on the walls of blood vessels, forming a build-up known as plaque. Treatments for atherosclerosis include drug therapy and open-heart bypass surgery. In addition, cardiologists are increasingly utilizing minimally invasive catheter-based treatments such as balloon angioplasty, atherectomy and laser angioplasty to treat atherosclerosis.

Although catheter-based interventional therapies are generally successful in initially increasing blood flow, studies indicate that after a traditional coronary balloon angioplasty up to 50% of treated patients experience restenosis (generally defined as a 50% or greater reduction in the lumen, or interior, diameter of the treated vessel at the lesion site). In addition, studies show that 5% to 8% of elective coronary balloon angioplasty patients may experience acute reclosure of the treated vessel. Acute reclosure is an increase in the severity of the vessel closure accompanied by a reduction in blood flow within the vessel as a consequence of the intervention which occurs within 24 hours of the procedure. A study has also indicated that angioplasty of chronic total occlusions represents 10% to 20% of all coronary angioplasty procedures. A chronic total occlusion is a complete blockage of the vessel preventing blood flow beyond the lesion site. The Company believes that these challenges are inadequately addressed with existing, single function, uniform diameter angioplasty balloons. However, while the Company believes that its products address certain disadvantages of existing catheter technology, limitations remain in the use of balloon angioplasty to treat atherosclerosis. The Company's products may not be suitable for the treament of all forms of atherosclerosis. For example, in many cases the existence of a total occlusion limits treatment options to bypass surgery.

CVD has utilized its core proprietary technologies to develop catheters that provide clinical and cost benefits in the treatment of vascular diseases. The Company's catheters are designed to address three principal challenges facing cardiologists: restenosis of a treated vessel, chronic total occlusions and acute reclosure of a vessel during or soon after a procedure. The Company's patented FOCAL technology combines compliant and non-compliant balloon materials on a single catheter, creating an angioplasty balloon that has an adjustable, larger center diameter with fixed, smaller diameters at each end. These characteristics allow a single balloon to expand to multiple diameters, enabling the physician to perform interventional procedures in vessels of varying diameters and anatomical locations. The Company's proprietary M3 technology combines multiple membranes of polymeric balloon material to form a single balloon that enables the accurate delivery of drugs or contrast agents to the lesion or thrombus site. The M3 technology can also be utilized to provide perfusion of blood during an interventional procedure. The Company believes that the FOCAL and M3 technologies may enable physicians to cost-effectively treat vascular diseases by reducing the cost of those procedures which require more than one catheter.

RISK FACTORS

In evaluating the Company's business, prospective investors should consider carefully the following risk factors in addition to the other information presented in this Prospectus. This Prospectus contains forward-looking statements that involve risks and uncertainties. The Company's actual results may differ materially from those described in the forward-looking statements. Investors should carefully consider the following risk factors in addition to the other information contained in this Prospectus before purchasing the Common Stock offered hereby.

History of Operating Losses; Anticipated Future Losses; Future Capital Requirements. The Company was founded in 1992 and has experienced annual operating losses since its inception. Its net loss in 1995 was $2.9 million. The Company's accumulated deficit at March 31, 1996 was $6.8 million. The Company expects to continue to incur operating losses through at least 1997 and there can be no assurance that the Company will ever be able to achieve or sustain profitability in the future. The Company expects to incur substantially increased costs related to, among other things, clinical testing, product development, manufacturing scale-up and sales and marketing activities. The Company anticipates that its existing capital resources, including the net proceeds from this offering and the interest earned thereon, will be sufficient to fund its operations through 1997. The Company's future capital requirements will depend on many factors, including its research and development programs, the scope and results of clinical trials, the time and costs involved in obtaining regulatory approvals, the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property, the status of competitive products, the establishment and scale-up of manufacturing capacity, the establishment of sales and marketing capabilities, the establishment of collaborative relationships with other parties and costs related to the acquisition of new technologies and product development. The Company may require additional funds to finance these activities and for working capital requirements. The Company may seek such funds through additional financings, including private or public equity or debt offerings and collaborative arrangements with corporate partners. There can be no assurance that funds will be raised on favorable terms, if at all. If adequate funds are not available, the Company may be required to delay, scale back or eliminate one or more of its development programs or obtain funds through arrangements with collaborative partners or others that may require the Company to relinquish rights to certain technologies, product candidates or products that the Company would not otherwise relinquish. See "Use of Proceeds" and "Management's Discussion and Analysis of Financial Condition and Results of Operations."

Limited Sales to Date; Uncertainty of Market Acceptance. The Company's catheters are used in conjunction with angioplasty and other intravascular procedures such as vascular stenting and drug delivery. Although the Company has received regulatory clearance for a total of thirty-two products, only eight of such products have been marketed. Of those products which have been marketed, many have been marketed only in limited quantities or in certain markets, or are allowed to be marketed only in certain countries. In addition, while interventional catheters are widely used technologies, the Company's catheter designs are relatively new. The commercial success of the Company's products will depend upon their acceptance by the medical community as useful, cost-effective components of interventional cardiovascular and peripheral vascular procedures, including the acceptance by the medical community of stents and the availability and acceptance of therapeutic drugs for use in interventional procedures. The Company currently relies upon relationships with certain prominent doctors and researchers in the medical community to promote the uses and acceptance of its approved products. There can be no assurance that the Company will be able to maintain such relationships or establish additional relationships in the future. The erosion or loss of any such relationship could detrimentally affect the market acceptance of the Company's products. Failure of the Company's products to achieve such market acceptance would have a material adverse effect on the Company's business, financial condition and results of operations. See "Business -- Products."

Dependence Upon New Products; Rapid Technological Change; Risk of Obsolescence. The medical device industry generally, and the interventional catheter market in particular, are characterized by rapid technological change, changing customer needs, and frequent new product introductions. As a result, the useful lives of both the technology and products for the treatment of cardiovascular and peripheral vascular diseases are limited, in some instances to as little as twelve months. The Company's future success will depend

6

upon its ability to develop, manufacture and introduce new products that address the needs of its customers. There can be no assurance that the Company will be successful in developing and marketing new products that achieve market acceptance or that the Company will not experience difficulties that could delay or prevent the successful development, introduction and marketing of new products. In addition, there can be no assurance that the Company's existing products will not be rendered obsolete as a result of technological developments or that the products that the Company has under development will not be rendered obsolete prior to the introduction of such products. See "Business -- Products."

Fluctuations in Quarterly Operating Results. CVD's results of operations have varied significantly from quarter to quarter. The Company has experienced an operating loss for each of the last three years. Quarterly operating results will depend upon several factors, including the timing and amount of expenses associated with expanding the Company's operations, the conduct of clinical trials and the timing of regulatory approvals, new product introductions both in the United States and internationally, the mix between pilot production of new products and full-scale manufacturing of existing products, the mix between domestic and export sales, variations in foreign exchange rates, changes in third-party payors' reimbursement policies and healthcare reform. The Company does not operate with a significant backlog of customer orders, and therefore revenues in any quarter are significantly dependent on orders received within that quarter. In addition, the Company cannot predict ordering rates by distributors, some of whom place infrequent stocking orders. The Company's expenses are relatively fixed and difficult to adjust in response to fluctuating revenues. As a result of these and other factors, the Company expects to continue to experience significant fluctuations in quarterly operating results, and there can be no assurance that the Company will be able to achieve or maintain profitability in the future. See "Management's Discussion and Analysis of Financial Condition and Results of Operations."

Reliance on Patents and Proprietary Technology; Risk of Patent Infringement. While the Company owns certain issued and allowed U.S. patents and has additional U.S. and foreign patent applications pending, there can be no assurance that the Company's patent applications will issue as patents or that any issued patents will provide competitive advantages for the Company's products or will not be successfully challenged or circumvented by its competitors. The interventional cardiovascular market in general and the market for balloon angioplasty catheters (including the type of catheters offered by
CVD) in particular has been characterized by substantial litigation regarding patent and other intellectual property rights. There can be no assurance that the Company's products do not infringe such patents or rights. In the event that any such parties assert claims against the Company for patent infringement and such patents are upheld as valid and enforceable, the Company could be prevented from utilizing the subject matter claimed in such patents, or would be required to obtain licenses from the owners of any such patents or redesign its products or processes to avoid infringement. There can be no assurance that such licenses would be available or, if available, would be so on terms acceptable to the Company or that the Company would be successful in any attempt to redesign its products or processes to avoid infringement. In addition, foreign intellectual property laws may not provide protection commensurate with that provided by U.S. intellectual property laws, and there can be no assurance that foreign intellectual property laws will adequately protect the Company's intellectual property rights abroad. The Company also relies on trade secrets and proprietary technology and enters into confidentiality and non-disclosure agreements with its employees, consultants and advisors. There can be no assurance that the confidentiality of such trade secrets or proprietary information will be maintained by employees, consultants, advisors or others, or that the Company's trade secrets or proprietary technology will not otherwise become known or be independently developed by competitors in such a manner that the Company has no practical recourse. Litigation may be necessary to defend against claims of infringement or invalidity, to enforce patents issued to the Company or to protect trade secrets, and there can be no assurance that any such litigation would be successful. Any litigation could result in substantial costs to, and diversion of resources by, the Company and its officers, which could have a material adverse effect on the Company's business, financial condition and results of operations. See "Business -- Patents and Proprietary Information."

Significant Competition. Competition in the market for devices used in the treatment of cardiovascular and peripheral vascular disease is intense, and is expected to increase. The interventional cardiology market is characterized by rapid technological innovation and change, and the Company's products could be rendered obsolete as a result of future innovations. The Company's catheters compete or will compete with catheters

7

marketed by a number of manufacturers, including Advanced Cardiovascular Systems, Inc., a subsidiary of Guidant Corporation ("ACS"), SCIMED Life Systems, Inc., a subsidiary of Boston Scientific Corporation ("SCIMED"), Johnson & Johnson Interventional Systems ("JJIS") and Cordis Corporation, subsidiaries of Johnson & Johnson, Medtronic, Inc., C.R. Bard, Inc. and Schneider USA, a subsidiary of Pfizer, Inc. Such companies have significantly greater financial, management and other resources, established market positions, and significantly larger sales and marketing organizations than does the Company. The Company also faces competition from manufacturers of other catheter-based devices, vascular stents and pharmaceutical products intended to treat vascular disease. In addition, the Company believes that many of the customers and potential customers of the Company's products prefer to purchase catheter products from a single source. Accordingly, many of the Company's competitors, because of their size and range of product offerings, have a competitive advantage over the Company. There can be no assurance that the Company's competitors will not succeed in developing or marketing technologies or products that are more clinically effective or cost effective than any that are being marketed or developed by the Company, or that such competitors will not succeed in obtaining regulatory approval for introducing or commercializing any such products prior to the Company. See "Business -- Competition."

Limited Manufacturing Experience. The Company's success will depend in part on its ability to manufacture its products in compliance with ISO 9001, the FDA's Good Manufacturing Practices ("GMP") regulations, California Department of Health Services ("CDHS") licensing and other regulatory requirements, in sufficient quantities and on a timely basis, while maintaining product quality and acceptable manufacturing costs. The Company began manufacturing certain of its products at its facilities in July 1995. Accordingly, the Company has very limited experience in manufacturing its products. In addition, the Company currently intends to introduce a significant number of new products in 1996. The Company has undergone and expects to continue to undergo regular GMP inspections in connection with the manufacture of its products at the Company's facilities. The Company's success will depend, among other things, on its ability to efficiently manage the simultaneous manufacture of different products and to integrate the manufacture of new products with existing products. There can be no assurance that the Company will not encounter difficulties in scaling up production of new products, including problems involving production yields, quality control and assurance, component supply and shortages of qualified personnel. The Company's failure to successfully commence the manufacturing of these new products, or to increase production volumes of new or existing products in a timely manner, would materially adversely affect the Company's business, financial condition and results of operations. Failure to increase production volumes in a timely or cost-effective manner or to achieve or maintain compliance with ISO 9001, GMP regulations, CDHS licensing or other regulatory requirements could have a material adverse effect on the Company's business, financial condition and results of operations.

The Company purchases many standard and custom built components from independent suppliers and subcontracts certain manufacturing processes from independent vendors. Most of these components and processes are available from more than one vendor. However, certain manufacturing processes are currently performed by single vendors. An interruption of performance by any of these vendors could have a material adverse effect on the Company's ability to manufacture its products until a new source of supply was qualified and, as a result, could have an adverse effect on the Company's business, financial condition and results of operations. See "Business -- Manufacturing" and "Business -- Government Regulation."

Potential Inability to Manage Growth. The Company has historically relied on EndoSonics to perform certain activities on its behalf, including manufacturing, financial, regulatory and administrative functions. Since July 1995, CVD has conducted its manufacturing operations at its facilities in Irvine and also currently performs the financial, regulatory and administrative functions previously performed by EndoSonics. Accordingly, the Company has experienced a period of significant expansion of its operations that has placed a significant strain upon its management systems and resources. The Company has recently implemented a number of new financial and management controls, reporting systems and procedures. In addition, the Company has recently hired a significant number of employees and plans to further increase its total headcount. The Company also plans to expand the geographic scope of its customer base and operations. This expansion has resulted and will continue to result in substantial demands on the Company's management

8

resources. The Company's ability to manage future expansion of its operations will require the Company to continue to improve its financial and management controls, reporting systems and procedures on a timely basis and to expand, train and manage its employee work force. There can be no assurance that the Company will be able to do so successfully. The failure to do so would have a material adverse effect on the Company's business, financial condition and results of operations.

Limited Marketing and Sales Resources; Dependence Upon Strategic Partners. CVD intends to rely primarily on certain strategic relationships, medical device distributors and its direct sales organization to distribute its products. The Company's ability to distribute its products successfully depends in part on the marketing capabilities of its strategic partners. In recent years there has been significant consolidation among medical device suppliers as the major suppliers have attempted to broaden their product lines in order to respond to cost pressures from health care providers. This consolidation has made it increasingly difficult for smaller suppliers, such as the Company, to effectively distribute their products without a relationship with one or more of the major suppliers. The Company is currently marketing certain of its products through licensing agreements with SCIMED and ACS. In addition, Fukuda Denshi Company, Ltd. ("Fukuda") is the Company's exclusive distributor in Japan for certain of the Company's products. Fukuda is also responsible for obtaining regulatory approval for the Company's products in Japan. The Company's revenue from these relationships is dependent upon the efforts made by such parties and there can be no assurance that such efforts will be successful. There can be no assurance that the Company will be able to maintain or expand its relationships with its strategic partners or to replace its strategic partners in the event any such relationship were terminated. In the event of such a termination, the Company's ability to distribute its products would be materially adversely affected, which would have a material adverse effect on the Company's business, financial condition and results of operations.

CVD currently has a limited marketing and sales staff. The Company intends to expand its direct sales force to market the Company's products, and intends to use a portion of the net proceeds from this offering to fund this expansion. However, there can be no assurance that CVD will successfully expand its direct sales and marketing organization, or that if expanded, such organization will be able to effectively distribute CVD's products. If CVD is unable to achieve distribution of its products through its direct sales organization, the Company's business, financial condition and results of operations would be materially adversely affected.

The Company also has product development relationships with SCIMED and ACS. SCIMED currently funds certain research and development efforts undertaken by CVD in the area of combined drug delivery and coronary angioplasty. ACS conducts development work on the Company's perfusion technology. If CVD is unable to maintain its relationships with these or future strategic partners its product development efforts could be materially adversely affected, which would materially adversely affect the Company's business, financial condition and results of operations. See "Business -- Marketing and Sales" and "Business -- Strategic Relationships."

Government Regulation. The manufacturing and marketing of the Company's products are subject to extensive and rigorous government regulation in the United States and in other countries. The Company believes that its success will be significantly dependent upon commercial sales of improved versions of its catheter products. The Company will not be able to market these new products in the United States unless and until the Company obtains approval or clearance from the FDA. Foreign and domestic regulatory approvals, if granted, may include significant limitations on the indicated uses for which a product may be marketed.

If a medical device manufacturer can establish that a newly developed device is "substantially equivalent" to a legally marketed Class I or Class II device, or to a Class III device that the FDA has not called for a premarket approval ("PMA"), the manufacturer may seek clearance from the FDA to market the device by filing a premarket notification with the FDA under Section 510(k) of the Federal Food, Drug, and Cosmetic Act ("510(k)"). All of the 510(k) clearances received for the Company's catheters were based on substantial equivalence to legally marketed devices. There can be no assurance that 510(k) clearance for any future product or significant modification of an existing product will be granted or that the process will not be unduly lengthy. In addition, if the FDA has concerns about the safety or effectiveness of any of the Company's products, it could act to withdraw approval or clearances of those products or request that the Company

9

present additional data. Any such actions would have a material adverse effect on the Company's business, financial condition and results of operations.

If substantial equivalence cannot be established, or if the FDA determines that the device or the particular application for the device requires a more rigorous review to assure safety and effectiveness, the FDA will require that the manufacturer submit a PMA application that must be reviewed and approved by the FDA prior to sales and marketing of the device in the United States. The PMA process is significantly more complex, expensive and time consuming than the 510(k) clearance process and always requires the submission of clinical data. It is expected that certain of the Company's products under development will be subject to this PMA process. The Company currently has a non-exclusive, royalty-free right to submit PMA supplement applications utilizing an EndoSonics PMA as a reference and to manufacture and distribute CVD products as a supplement to the EndoSonics PMA. This agreement may be terminated in the event of breach upon 60 days notice by the non-breaching party, subject to the breaching party's right to cure. In the event of termination, the Company would be prohibited from submitting new PMA supplements referencing the EndoSonics PMA and would be required to seek independent FDA approval for any such products, which would have a material adverse effect on the Company's business, financial condition and results of operations.

The Company is also required to register as a medical device manufacturer with the FDA and maintain a license with certain state agencies, such as the CDHS. As such, the Company is inspected on a routine basis by both the FDA and the CDHS for compliance with GMP regulations. These regulations require that the Company manufacture its products and maintain related documentation in a prescribed manner with respect to manufacturing, testing and control activities. The Company has also undergone and expects to continue to undergo regular GMP inspections in connection with the manufacture of its products at the Company's facilities. Further, the Company is required to comply with various FDA requirements for labeling. The Medical Device Reporting laws and regulations require that the Company provide information to the FDA on deaths or serious injuries alleged to have been associated with the use of its devices, as well as product malfunctions that would likely cause or contribute to death or serious injury if the malfunction were to recur. In addition, the FDA prohibits an approved device from being marketed for unapproved applications. CVD has received FDA approval to market the FACT catheters, which utilize the FOCAL technology, for coronary balloon angioplasty. These catheters are marketed outside the United States for use in stent deployment. However, without specific FDA approval for stent deployment, these catheters may not be marketed by the Company in the United States for such use.

Failure to comply with applicable regulatory requirements can, among other consequences, result in fines, injunctions, civil penalties, suspensions or loss of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution. In addition, government regulations may be established in the future that could prevent or delay regulatory clearance or approval of the Company's products. Delays in receipt of clearances or approvals, failure to receive clearances or approvals or the loss of previously received clearances or approvals would have a material adverse effect on the Company's business, financial condition and results of operations.

The Company is also subject to other federal, state and local laws, regulations and recommendations relating to safe working conditions, laboratory and manufacturing practices. The extent of government regulation that might result from any future legislation or administrative action cannot be accurately predicted. Failure to comply with regulatory requirements could have a material adverse effect on the Company's business, financial condition and results of operations. See "Business -- Products" and "Business -- Government Regulation."

International sales of the Company's products are subject to the registration requirements of each country. The regulatory review process varies from country to country and may in some cases require the submission of clinical data. The Company typically relies on its distributors in such foreign countries to obtain the requisite regulatory approvals. There can be no assurance, however, that such approvals will be obtained on a timely basis or at all. In addition, the FDA must approve the export to certain countries of devices that require a PMA but are not yet approved domestically.

10

The Company is in the process of implementing policies and procedures which are intended to allow the Company to receive ISO 9001 certification of its quality system. The ISO 9000 series of standards for quality operations has been developed to ensure that companies know the standards of quality to which they must adhere to receive certification. The European Union has promulgated rules which require that medical products receive by mid-1998 the right to affix the CE mark, an international symbol of adherence to quality assurance standards and compliance with applicable European medical device directives. ISO 9001 certification is one of the CE mark certification requirements. Failure to receive the right to affix the CE mark will prevent the Company from selling its products in member countries of the European Union. While the Company is in the process of becoming ISO 9001 certified, there can be no assurance that the Company will be successful in meeting these or any other certification requirements on a timely basis, or at all.

Limitations on Third-Party Reimbursement. In the United States, the Company's products are purchased primarily by medical institutions, which then bill various third-party payors, such as Medicare, Medicaid, and other government programs and private insurance plans, for the health care services provided to patients. Government agencies, private insurers and other payors determine whether to provide coverage for a particular procedure and reimburse hospitals for medical treatment at a fixed rate based on the diagnosis-related group ("DRG") established by the U.S. Health Care Financing Administration ("HCFA"). The fixed rate of reimbursement is based on the procedure performed, and is unrelated to the specific devices used in that procedure. If a procedure is not covered by a DRG, payors may deny reimbursement. In addition, some payors may deny reimbursement if they determine that the device used in a treatment was unnecessary, inappropriate or not cost-effective, experimental or used for a non-approved indication. Reimbursement of interventional procedures utilizing the Company's products is currently covered under a DRG. There can be no assurance that reimbursement for such procedures will continue to be available, or that future reimbursement policies of payors will not adversely affect the Company's ability to sell its products on a profitable basis. In addition, reimbursement may be denied if the product use is not in accordance with approved FDA labeling. Failure by hospitals and other users of the Company's products to obtain reimbursement from third-party payors, or changes in government and private third-party payors' policies toward reimbursement for procedures employing the Company's products, would have a material adverse effect on the Company's business, financial condition and results of operations. See "Business -- Third-Party Reimbursement."

Dependence Upon International Sales. The Company derives, and expects to continue to derive, a significant portion of its revenue from international sales. In 1995 and the three months ended March 31, 1996, the Company's international sales were $2.1 million and $1.1 million, respectively, or 59% and 64%, respectively, of product sales. The Company expects to continue to derive significant revenue from international sales and therefore a significant portion of the Company's revenues will continue to be subject to the risks associated with international sales, including economic or political instability, shipping delays, changes in applicable regulatory policies, inadequate protection of intellectual property, fluctuations in foreign currency exchange rates and various trade restrictions, all of which could have a significant impact on the Company's ability to deliver products on a competitive and timely basis. Future imposition of, or significant increases in the level of, customs duties, import quotas or other trade restrictions, could have an adverse effect on the Company's business, financial condition and results of operation. In foreign countries, the Company's products are subject to governmental review and certification. The regulation of medical devices, particularly in the European Union, continues to expand and there can be no assurance that new laws or regulations will not have an adverse effect on the Company's business, financial condition and results of operations. See "Management's Discussion and Analysis of Financial Condition and Results of Operations."

Control by Existing Stockholder; Limitations on Pooling-of-Interests Accounting in Merger Transactions. After this offering, EndoSonics will own approximately 49% of the Company's outstanding Common Stock. EndoSonics will be able to elect at least two members to the Company's five person board of directors and will have the ability to effectively control the Company and influence its affairs and the conduct of its business. Such concentration of ownership may have the effect of delaying, deferring or preventing a change in control of the Company. In accordance with applicable accounting standards, the Company would be prohibited from accounting for a merger transaction, of or by the Company, as a pooling-of-interests for a period of two years following the date on which EndoSonics controls less than 50% of the outstanding voting Common Stock of

11

the Company. As a result, any business combination consummated during such period would have to be accounted for using the purchase method. Under the purchase method, the excess of the purchase price over the net book value of the assets acquired would be amortized to expense, which could result in a significant negative impact on the acquiror's results of operations and, therefore, reduce the attractiveness of, or the price paid in, a particular acquisition transaction.

EndoSonics has informed the Company that EndoSonics presently intends to distribute or otherwise transfer to EndoSonics stockholders a portion of the CVD shares it will hold on consummation of this offering. While EndoSonics indicated that it may so distribute or transfer up to a majority of the shares it will hold, it also indicated that the precise amount and timing of any such distribution or transfer will depend upon, among other matters, an analysis of the tax consequences to EndoSonics and its stockholders. Any such distribution or transfer may result in a change of control of CVD. Notwithstanding EndoSonics' stated intent, EndoSonics is not obligated to make any such distribution or transfer nor is it obligated to take any action or refrain from taking any action with respect to the shares of CVD which it will hold upon completion of this offering. See "Certain Transactions."

Dependence Upon Key Personnel. The Company depends to a significant extent upon key management and technical personnel. The Company's growth and future success will depend in large part upon its ability to hire, motivate and retain highly qualified personnel. Competition for such personnel is intense and there can be no assurance that the Company will be successful in hiring, motivating or retaining such qualified personnel. The loss of key personnel or the inability to hire or retain qualified personnel could have a material adverse effect on the Company's business, financial condition and results of operations. See "Business -- Marketing and Sales," "Business -- Employees" and "Management."

Potential Product Liability; Limited Insurance. The Company faces the risk of financial exposure to product liability claims. The Company's products are often used in situations in which there is a high risk of serious injury or death. Such risks will exist even with respect to those products that have received, or in the future may receive, regulatory approval for commercial sale. The Company is currently covered under EndoSonics' product liability insurance policy with coverage limits of $2.0 million per occurrence and $2.0 million per year in the aggregate. However, this coverage will terminate when the Company ceases to be a majority-owned subsidiary of EndoSonics. Accordingly, following this offering, the Company expects to obtain product liability insurance with similar coverage limits. There can be no assurance that the Company's product liability insurance is adequate or that such insurance coverage will remain available at acceptable costs. There can be no assurance that the Company will not incur significant product liability claims in the future. A successful claim brought against the Company in excess of its insurance coverage could have a material adverse effect on the Company's business, financial condition and results of operations. Additionally, adverse product liability actions could negatively affect the reputation and sales of the Company's products and the Company's ability to obtain and maintain regulatory approval for its products and substantially divert the time and effort of management away from the Company's operations.

No Prior Public Market; Possible Volatility of Stock Price. Prior to this offering, there has been no public market for the Common Stock, and there can be no assurance that an active trading market will develop or be sustained. The initial public offering price will be determined by negotiation between the Company and the Representatives of the Underwriters based upon several factors, and may not be indicative of the market price of the Common Stock after this offering. The trading price of the Common Stock could also be subject to significant fluctuations in response to variations in quarterly results of operations, any future litigation involving the Company, announcements of technological innovations or new products by the Company or its competitors, governmental regulatory action, other developments or disputes with respect to proprietary rights, general trends in the industry and overall market conditions, and other factors. See "Underwriting."

Shares Eligible for Future Sale; Potential Adverse Effect on Market Price. Sales of Common Stock in the public market after this offering could adversely affect the market price of the Common Stock. The 3,400,000 shares sold in this offering will be freely tradable without restriction. Beginning 180 days following

12

the date of this offering (or earlier with the consent of Volpe, Welty & Company), approximately 4,000,000 shares will be eligible for sale, representing 3,240,000 shares held by EndoSonics and 760,000 shares held by SCIMED. Sales of any such shares in the public market after this offering could adversely affect the market price of the Common Stock. The Company also intends to register approximately 1,200,000 shares of Common Stock reserved for issuance under the Company's 1996 Stock Option/Stock Issuance Plan and 200,000 shares under the Company's Employee Stock Purchase Plan as soon as practicable following the date of this Prospectus. As of March 31, 1996, there were outstanding options under the Company's stock option plans to acquire 977,000 shares, all of which are subject to 180-day lock-up agreements with the Underwriters. After the expiration of the 180-day lock-up period, SCIMED will be entitled to certain demand and piggyback registration rights with respect to its shares. If SCIMED, by exercising its demand registration rights, causes a large number of shares to be registered and sold in the public market, such sales could have an adverse effect on the market price for the Common Stock. If the Company were required to include in a Company-initiated registration shares held by SCIMED pursuant to the exercise of its piggyback registration rights, such sales may have an adverse effect on the Company's ability to raise needed capital. See "Shares Eligible for Future Sale."

Effect of Certain Charter Provisions; Anti-takeover Effects of Certificate of Incorporation, Bylaws and Delaware Law. The Company's Board of Directors has the authority to issue up to 5,000,000 shares of Preferred Stock and to determine the price, rights, preferences, privileges and restrictions, including voting rights, of those shares without any further vote or action by the stockholders. The rights of the holders of Common Stock will be subject to, and may be adversely affected by, the rights of the holders of any Preferred Stock that may be issued in the future. The issuance of Preferred Stock could have the effect of making it more difficult for a third party to acquire a majority of the outstanding voting stock of the Company. In addition, the Company is subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law, which will prohibit the Company from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. The application of Section 203 also could have the effect of delaying or preventing a change of control of the Company. Further, certain provisions of the Company's Certificate of Incorporation and Bylaws and of Delaware law could delay or make more difficult a merger, tender offer or proxy contest involving the Company, which could adversely affect the market price of the Company's Common Stock. See "Description of Capital Stock."

Absence of Dividends; Dilution. The Company has never paid any cash dividends on the Common Stock and does not anticipate paying any cash dividends on the Common Stock in the foreseeable future. Purchasers of the Common Stock offered hereby will incur immediate substantial dilution in the net tangible book value per share of Common Stock. See "Dividend Policy" and "Dilution."

THE COMPANY

The Company was originally incorporated in California in March 1992 and became a Delaware corporation in June 1993 after being acquired by EndoSonics. The Company's principal executive offices are located at 13900 Alton Parkway, Suite 122, Irvine, California 92718 and its telephone number is (714) 457-9546.

USE OF PROCEEDS

The net proceeds from the sale of the 3,400,000 shares of Common Stock offered hereby at an assumed initial public offering price of $12.00 per share are estimated to be $37,174,000 ($42,866,000 if the Underwriters' over-allotment option is exercised in full) after deducting underwriting discounts and commissions and estimated offering expenses payable by the Company.

The Company anticipates that approximately $12 million of the net proceeds will be used in continuing product development and that approximately $5 million will be used for capital expenditures. The Company also intends to pay the $2.6 million payable to EndoSonics from the net proceeds of this offering. A portion of the net proceeds will be used to fund the expansion of the Company's sales and marketing capabilities and the balance will be used for working capital and other general corporate purposes. The Company may also spend a portion of the proceeds to license or acquire products or technologies complementary to its business and to conduct additional research and development programs. Pending such uses, the Company intends to invest the net proceeds in short-term, interest-bearing, investment grade securities.

The exact allocation of the proceeds for the purposes set forth above and timing of the expenditures may vary significantly depending upon numerous factors, including research and development programs, the scope and results of clinical trials, the time and costs involved in obtaining regulatory approvals, the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual property, the status of competitive products, the establishment of manufacturing capacity or third-party manufacturing arrangements, the establishment of sales and marketing capabilities, the establishment of collaborative relationships with other parties, and the costs of manufacturing scale-up. There can be no assurance that the proceeds of this offering, after deducting cash used in the Company's operations will be adequate to fund these activities. If adequate funds are not available, the Company may be required to delay, scale back or eliminate one or more of its development programs or obtain funds through arrangements with collaborative partners or others that may require the Company to relinquish rights to certain technologies, product candidates or products that the Company would not otherwise relinquish.

The Company anticipates that its existing capital resources, including the net proceeds of this offering and the interest earned thereon will be sufficient to fund its operations through 1997. However, there can be no assurance that the Company will not be required to seek additional financing sooner or that such financing, if required, will be available on terms satisfactory to the Company. See "Risk Factors -- History of Operating Losses; Anticipated Future Losses; Future Capital Requirements" and "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources."

DIVIDEND POLICY

The Company has not paid dividends since its inception. The Company currently intends to retain all earnings, if any, for use in the expansion of its business and therefore does not anticipate paying any dividends in the foreseeable future.

CAPITALIZATION

The following table sets forth the actual capitalization of the Company as of March 31, 1996 and the capitalization as adjusted to reflect the receipt of the estimated net proceeds from the sale of 3,400,000 shares of Common Stock at an assumed initial public offering price of $12.00 pursuant to this offering and the conversion of all outstanding shares of Preferred Stock into Common Stock upon the closing of this offering:

                                                                             MARCH 31, 1996
                                                                        -------------------------

DILUTION

The net tangible book value of the Company's Common Stock as of March 31, 1996 was $6,551,000, or approximately $1.35 per share. Net tangible book value per share represents the amount of the Company's stockholders' equity, less intangible assets, divided by 4,862,500 shares of Common Stock outstanding after giving effect to the conversion of the Convertible Obligation and all outstanding shares of Preferred Stock into Common Stock upon completion of this offering. After giving effect to the sale of 3,400,000 shares of Common Stock in this offering at an assumed initial public offering price of $12.00 and the application of the estimated net proceeds therefrom, the net tangible book value of the Company as of March 31, 1996 would have been $44,475,000 or $5.38 per share. This represents an immediate increase in net tangible book value of $3.97 per share to existing stockholders and an immediate dilution in net tangible book value of $6.67 per share to purchasers of Common Stock in this offering. Investors participating in this offering will incur immediate, substantial dilution. This is illustrated in the following table:

Assumed initial public offering price per share....................             $12.00
  Net tangible book value per share as of March 31, 1996...........  $ 1.35

As of March 31, 1996, there were options outstanding to purchase a total of 977,000 shares of Common Stock at a weighted average exercise price of $1.21 per share under the Company's 1995 Stock Option Plan and a warrant outstanding to purchase a total of 80,000 shares of Common Stock at an exercise price of $3.29 per share. Subsequent to March 31, 1996 the Company issued an additional warrant to purchase a total of 40,000 shares of Common Stock at an exercise price of $3.29 per share. To the extent outstanding options and warrants are exercised, there will be further dilution to new investors.

The following table sets forth as of March 31, 1996, after giving effect to the conversion of the Convertible Obligation and all outstanding shares of Preferred Stock into Common Stock upon the closing of this offering, the difference between the number of shares of Common Stock purchased from the Company, the total consideration paid and the average price per share paid by existing stockholders and by the new investors purchasing shares in this offering at an assumed initial public offering price of $12.00 per share and before deducting underwriting discounts and estimated offering expenses payable by the Company:

MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Prospectus contains certain forward-looking statements. The Company's actual results may differ materially from those described in the forward-looking statements. Investors should carefully consider the information set forth under the heading "Risk Factors" in addition to the other information contained in this Prospectus before purchasing the Common Stock offered hereby.

OVERVIEW

CVD designs, develops, manufactures and markets catheters used to treat certain vascular diseases. The Company's patented catheters utilize its FOCAL and M3 technologies to deliver therapeutic radial pressure, stents, drugs or contrast media and improved blood flow during angioplasty and stent placement procedures. To date, the majority of the Company's revenue has been derived from sales of its angioplasty and angioplasty-related catheters.

From inception (March 16, 1992) through the first quarter of 1994, the Company operations were limited and consisted primarily of research and development and other start-up activities. On June 15, 1992, EndoSonics acquired a 40% interest in CVD in exchange for $0.5 million in cash. Pursuant to an Agreement and Plan of Reorganization between EndoSonics and CVD signed on June 9, 1993, EndoSonics acquired all of the outstanding capital stock of CVD in exchange for $0.3 million in cash and 250,000 shares of EndoSonics' Common Stock with an aggregate market value of $1.6 million. The acquisition by EndoSonics resulted in a new basis for CVD's assets and liabilities. Accordingly, the purchase price paid by EndoSonics has been allocated to CVD's identifiable assets and liabilities, including $2.0 million to acquired in-process research and development, which was immediately expensed, as no CVD products had received regulatory approval and the technology did not have alternative future uses. Pursuant to the terms of the Agreement and Plan of Reorganization, in June 1995, EndoSonics became obligated to issue 50,000 shares of its Common Stock with an aggregate market value of $0.5 million, to the former shareholders of CVD because the market price of EndoSonics' stock did not exceed a specified price for a specified period during the two-year period following the acquisition. The fair value of such shares was charged to acquired in-process technology. In addition, EndoSonics recently purchased 400,000 shares of CVD's Series B Preferred Stock for a purchase price of $8.0 million, which will convert into 800,000 shares of Common Stock upon the consummation of this offering. See "Certain Transactions -- Relationship with EndoSonics Corporation."

In September 1994, CVD and SCIMED entered into a Stock Purchase and Technology License Agreement to develop and license CVD's patented combination balloon angioplasty/site-specific drug delivery technology (the Transport product line) for use in the coronary vessels. Through March 31, 1996 the Company had received in the aggregate approximately $2.0 million in license fees, research and development funding and technical assistance from SCIMED under this agreement. SCIMED also purchased a 19% equity position in the Company for a purchase price of $2.5 million. See "Business -- Strategic Relationships."

In January 1995, the Company and ACS entered into an agreement pursuant to which the Company acquired certain rights to ACS' SmartNeedle Technology, subject to the payment of certain royalties. The parties subsequently confirmed their understanding with respect to certain matters in a second agreement dated March 4, 1996 (collectively, the "ACS Agreements"). Pursuant to the ACS Agreements, ACS was granted the option to acquire the exclusive worldwide rights to certain CVD perfusion technology, which ACS exercised on February 14, 1996. In exchange for this perfusion technology, ACS is obligated to make milestone and minimum annual royalty payments to CVD, and also has certain obligations to develop and market the perfusion technology. Through March 31, 1996 the Company had received approximately $0.2 million in milestone payments under the ACS Agreements. See "Business -- Strategic Relationships."

The Company currently sells its products through a combination of medical device distributors and a limited number of direct sales personnel. The Company is a party to three agreements for the U.S. distribution of products incorporating its FOCAL and M3 technologies. CVD distributes certain products in Japan through an exclusive distribution agreement with Fukuda. CVD also has distribution agreements with 18 companies covering 35 countries outside the United States and Japan. See "Business -- Strategic Relationships."

18

Based on the Company's limited operations in 1993, the Company believes that a year-to-year comparison of 1994 to 1993 is not meaningful and has not included such a comparison in the discussion that follows.

RESULTS OF OPERATIONS

Years Ended December 31, 1994 and December 31, 1995

Sales Revenue. Sales revenue increased to $3.5 million in 1995 from $1.2 million in 1994, representing an increase of 196%. Sales revenue in 1994 resulted primarily from sales of the Company's Transport products, which were subsequently licensed to SCIMED in 1995. The Company no longer receives sales revenue for the Transport. Sales revenue in 1995 was due to sales of the Company's CAT catheter, which was introduced in the first quarter of 1995, and sales of the SmartNeedle vascular access products beginning in the second quarter of 1995. Sales of products in Japan through the Company's exclusive distribution relationship with Fukuda accounted for 18% of the Company's revenue in 1995. In addition, sales to JJIS accounted for 12% of the Company's revenue in 1995.

License Fee and Other Revenue from Related Party. License fee and other revenue represents amounts earned under the aforementioned agreement with SCIMED. The 1994 amount consists of a $1.0 million license fee and $0.2 million of development and other revenue. The 1995 amount consists of $0.6 million of development and other revenue. Future revenue under this agreement will be derived primarily from royalties earned on SCIMED's sales of the Transport.

Cost of Sales. Cost of sales increased to $2.1 million in 1995 from $0.8 million in 1994, representing an increase of 142%. This increase resulted primarily from increased manufacturing volumes related to increased product sales. In July 1995, the Company transferred its product manufacturing from EndoSonics' facility to the Company's facility in Irvine, California.

Charge for Acquired In-process Research and Development. The Company incurred a charge of $0.5 million in 1995 in connection with the 1995 payment by EndoSonics of additional consideration related to the original acquisition by EndoSonics of CVD stock. This portion of the excess of the purchase price of CVD over the fair market value of the net assets acquired was recorded as in-process research and development. The acquired in-process research and development was immediately written off as CVD was in the development stage and had not yet received regulatory approval for any of its products at the time of the acquisition.

Research and Development. Research and development expenses increased to $1.7 million in 1995 compared to $1.2 million in 1994, representing an increase of 37%. This increase was due primarily to increased expenditures related to development of the Company's FOCAL and M3 technology products. These expenses also increased due to clinical trials and studies related to the FOCAL technology products. The Company believes that it must maintain a substantial commitment to research and development to remain competitive and expects expenditures related to research and development to increase.

Marketing and Sales. Marketing and sales expenses increased to $1.5 million in 1995 from $0.7 million in 1994, representing an increase of 104%. This increase resulted from the development and expansion of the Company's U.S. sales organization and marketing expenses related to the product launch of the SmartNeedle products. The Company expects to expand its marketing and sales force and expects expenses associated with marketing and sales to increase in the future.

General and Administrative. General and administrative expenses increased to $1.3 million in 1995 from $0.6 million in 1994, representing an increase of 127%. This increase resulted from expenses incurred as the Company commenced operations as an independent entity, rather than as a division of EndoSonics, and included the addition of a full-time Chief Executive Officer, increased legal and accounting expenses, increased support staff and increased travel expenses.

Other Income. Total other income remained relatively constant from 1994 to 1995.

19

Three Months Ended March 31, 1995 and March 31, 1996

Sales Revenue. Sales revenue increased to $1.8 million in the three months ended March 31, 1996 from $0.2 million in the three months ended March 31, 1995, representing increased sales of the Company's FOCAL catheters, and the introduction of additional products. Sales of products in Japan through the Company's exclusive distribution relationship with Fukuda accounted for 22% of the Company's revenue in the three months ended March 31, 1996.

License Fees and Other Revenue. License fees and other revenue from SCIMED decreased to $0.1 million in the three months ended March 31, 1996 from $0.2 million in the three months ended March 31, 1995 due to scheduled payment reductions in accordance with the provisions of the licensing agreement with SCIMED.

Contract Revenue. Contract revenue was $0.2 million in the three months ended March 31, 1996 and results from amounts earned under the ACS Agreements. The Company had no such revenues in 1995.

Cost of Sales. Cost of sales increased to $0.9 million in the three months ended March 31, 1996 from $0.1 million in the comparable period in 1995. This increase resulted primarily from increased manufacturing volumes related to increased product sales. In July 1995, the Company transferred its product manufacturing from EndoSonics' facility to the Company's facility in Irvine, California.

Research and Development. Research and development increased to $0.6 million in the three months ended March 31, 1996 compared to $0.4 million in the three months ended March 31, 1995, representing an increase of 45%. This increase resulted primarily from expenditures on the development of FOCAL technology and vascular access products. The Company believes that it must maintain a substantial commitment to research and development to remain competitive and expects expenditures related to research and development to increase.

Marketing and Sales. Marketing and sales expenses increased to $0.6 million in the three months ended March 31, 1996 from $0.3 million in the comparable period in 1995, representing an increase of 126%. This increase resulted mainly from the expansion of the Company's direct sales force in the United States and marketing expenses related to the product launch of the FACT catheter. The Company expects to expand its marketing and sales resources and expects expenses associated with these activities to increase in the future.

General and Administrative. General and administrative expenses remained unchanged at approximately $0.3 million in both the three months ended March 31, 1996 and 1995.

Other Income. Other income, principally interest income, remained unchanged in both the three months ended March 31, 1996 and 1995.

The Company has experienced an operating loss for each of the last three years. The Company expects to continue to incur operating losses through at least 1997 and there can be no assurance that the Company will ever be able to achieve or sustain profitability in the future. CVD's results of operations have varied significantly from quarter to quarter. Quarterly operating results will depend upon several factors, including the timing and amount of expenses associated with expanding the Company's operations, the conduct of clinical trials and the timing of regulatory approvals, new product introductions both in the United States and internationally, the mix between pilot production of new products and full-scale manufacturing of existing products, the mix between domestic and export sales, variations in foreign exchange rates, changes in third-party payors' reimbursement policies and healthcare reform. The Company does not operate with a significant backlog of customer orders, and therefore revenues in any quarter are significantly dependent on orders received within that quarter. In addition, the Company cannot predict ordering rates by distributors, some of whom place infrequent stocking orders. The Company's expenses are relatively fixed and difficult to adjust in response to fluctuating revenues. As a result of these and other factors, the Company expects to continue to experience significant fluctuations in quarterly operating results, and there can be no assurance that the Company will be able to achieve or maintain profitability in the future.

20

LIQUIDITY AND CAPITAL RESOURCES

Since inception, the Company has financed its operations primarily from the sale of its equity securities, advances from EndoSonics, licensing its technologies and through international product distribution agreements. From inception through March 31, 1996, the Company raised approximately $11.4 million from the private sales of Preferred and Common Stock and $2.6 million in working capital from EndoSonics. The Company intends to repay EndoSonics with a portion of the proceeds from this offering. The Company has also received $0.2 million and $2.0 million in licensing and contract revenue from ACS and SCIMED, respectively, as well as $0.8 million from Fukuda in connection with an exclusive distribution agreement. For the years ended December 31, 1995 and 1994, the Company's net cash used in operating activities was $2.1 million and $1.5 million, respectively. The increase was primarily due to funding of operating losses.

On March 31, 1996, the Company had cash, cash equivalents and short-term investments of $8.7 million. The Company expects to incur substantial costs related to, among other things, clinical testing, product development, marketing and sales expenses, and increased working capital, prior to achieving positive cash flow from operations. The Company anticipates that its existing capital resources, together with the net proceeds from this offering and the interest earned thereon, will be sufficient to fund its operations through 1997. The Company's future capital requirements will depend on many factors, including its funding requirements, research and development programs, the scope and results of clinical trials, the regulatory approval process, the costs involved in intellectual property rights enforcement or litigation, competitive products, the establishment of manufacturing capacity, the establishment of sales and marketing capabilities, and the establishment of collaborative relationships with other parties. The Company may need to raise funds through additional financings, including private or public equity offerings and collaborative arrangements with existing or new corporate partners. There can be no assurance that funds will be raised on favorable terms, or at all. If adequate funds are not available, the Company may be required to delay, scale back or eliminate one or more of its development programs or obtain funds through arrangements with collaborative partners or others that may require the Company to grant rights to certain technologies or products that the Company would not otherwise grant.

BUSINESS

OVERVIEW

CardioVascular Dynamics, Inc. ("CVD" or the "Company") designs, develops, manufactures and markets catheters used to treat certain vascular diseases. The Company's catheters are used in conjunction with angioplasty and other interventional procedures such as vascular stenting and drug delivery. The Company's proprietary FOCAL and Multiple Microporous Membrane ("M3") technologies enable physicians to deliver therapeutic radial force, stents, drugs or contrast media accurately and effectively to the treatment site, and also allow the perfusion of blood during an interventional procedure. The Company believes that the combination of these technologies on a multiple purpose catheter enables physicians to more effectively perform challenging interventional procedures, which may result in improved treatment outcomes and lower costs. The Company's catheters are designed to address three principal challenges facing cardiologists: restenosis of a treated vessel, chronic total occlusions and acute reclosure of a vessel during or soon after a procedure. The Company has five issued and four allowed U.S. patents covering certain aspects of its catheter technologies. Since commencing commercial sales in 1994, the Company has sold more than 12,000 catheters.

INDUSTRY BACKGROUND

Cardiovascular disease, the leading cause of death in the United States, is caused principally by atherosclerosis. Atherosclerosis is a progressive and degenerative vascular disease in which cholesterol and other fatty materials are deposited on the walls of blood vessels, forming a build-up known as plaque. The accumulation of plaque narrows the interior of the blood vessels, thereby reducing blood flow. Atherosclerosis in the coronary arteries can lead to heart attack and death. In peripheral vessels, atherosclerosis can lead to decreased mobility, loss of function and other complications of the affected limb.

Traditional treatments for atherosclerosis include drug therapy and open-heart bypass surgery. Currently available drug therapies may alleviate some of the symptoms of atherosclerosis but may be ineffective with severe disease and may cause adverse side effects. Traditional open-heart bypass surgery involves opening a patient's chest, cutting through the sternum, connecting the patient to a heart/lung machine and grafting a blood vessel to redirect blood flow around the occluded portion of an artery. Such a procedure is costly and generally requires up to a week of hospitalization and an extensive recovery period. In addition, certain companies are developing methods and devices for performing bypass surgery using minimally invasive techniques.

The need for less invasive and less costly treatments for atherosclerosis has led to the development of minimally invasive catheter-based treatments such as balloon angioplasty ("PTCA" in the coronary arteries and "PTA" in the peripheral arteries), atherectomy and laser angioplasty. These treatments involve making a small incision in a patient's leg to access an artery and inserting a catheter. Balloon angioplasty is a procedure in which a balloon-tipped catheter is guided to the lesion (the site of the plaque) and then inflated and deflated several times, delivering therapeutic radial force, which cracks or reshapes the plaque and increases blood flow. Balloons used to perform such procedures are characterized by their response to pressure as either compliant (balloon diameter increases with increased pressure) or non-compliant (balloon diameter remains relatively constant with increasing pressure). Conventional balloon technology only allows the balloon to expand to a single, uniform diameter along the length of the balloon. Because of variations in vessel diameters at the lesion site, multiple catheters are often required to treat a single lesion. In addition, conventional catheter technologies often are unable to limit the delivery of therapeutic radial force specifically to the lesion site and may damage the adjacent vessel wall. Conventional catheter technology also interrupts blood flow when the balloon is inflated, which may cause tissue damage, heart attack or death, particularly if the balloon inflation required is of significant duration. Existing catheters that do not perfuse blood require cardiologists to inflate and deflate the balloon multiple times which may reduce the clinical effectiveness of the treatment. Other treatments include the use of atherectomy catheters, which cut or grind away the plaque, and laser angioplasty catheters, which deliver laser energy to break down the plaque.

22

Although catheter-based interventional therapies are generally successful in initially increasing blood flow, studies indicate that after a traditional coronary balloon angioplasty up to 50% of treated patients experience restenosis (generally defined as a 50% or greater reduction in the lumen, or interior, diameter of the treated vessel at the lesion site). In addition, studies show that 5% to 8% of elective coronary balloon angioplasty patients may experience acute reclosure of the treated vessel. Acute reclosure is an increase in the severity of the vessel closure accompanied by a reduction in blood flow within the vessel as a consequence of the intervention which occurs within 24 hours of the procedure. A study has also indicated that angioplasty of chronic total occlusions represents 10% to 20% of all coronary angioplasty procedures. A chronic total occlusion is a complete blockage of the vessel preventing blood flow beyond the lesion site. The Company believes that these challenges are inadequately addressed with existing, single function, uniform diameter angioplasty balloons. However, while the Company believes that its products address certain disadvantages of existing catheter technology, limitations remain in the use of balloon angioplasty to treat atherosclerosis. The Company's products may not be suitable for the treatment of all forms of atherosclerosis. For example, in many cases the existence of a total occlusion limits treatment options to bypass surgery.

Coronary stents have recently emerged as an additional minimally invasive device for the treatment of atherosclerosis. Stents were used initially for treating failed angioplasty procedures and acute or threatened vessel closures. However, improved techniques for the deployment and assessment of stents, changes in accompanying drug therapy and advancements in stent technology have led to the increased use of stents to treat restenosis. After an angioplasty, atherectomy or other catheter-based treatment, a stent, which is a small metal prostheses, is then advanced along a guidewire to the desired position, expanded against the inside of the vessel wall and left in place. While certain stents are self-expanding, most are deployed through the expansion of a compliant or semi-compliant balloon. Following this deployment, physicians have increasingly adopted the technique of using a second, high pressure non-compliant balloon to further expand the stent. Despite advancements in stent technology, existing compliant or semi-compliant balloons used for stent delivery are designed to achieve a uniform diameter along the length of the balloon, and their use may result in sub-optimal stent deployment or damage of the vessel adjacent to the lesion.

Although there continue to be significant technological and clinical advances in the treatment of cardiovascular disease, challenges remain in cost-effectively treating certain conditions, including restenosis of a treated vessel, chronic total occlusions and acute reclosure of a vessel during or soon after a procedure. The Company believes that these challenges are inadequately addressed with existing, single function, uniform diameter angioplasty balloons.

THE CARDIOVASCULAR DYNAMICS SOLUTION

CVD has utilized its core proprietary technologies to develop catheters that provide clinical and cost benefits in the treatment of vascular disease. The Company's proprietary FOCAL and M3 technologies, which may be utilized alone or in combinations on a single catheter, enable physicians to deliver therapeutic radial force, stents, drugs or contrast media accurately to the treatment site, and also allow the perfusion of blood during an interventional procedure. The Company believes that the combination of these technologies on a single catheter enables physicians to cost-effectively treat vascular diseases by reducing the cost of those procedures that require more than one catheter.

The Company's patented FOCAL technology combines compliant and non-compliant balloon materials on a single catheter, creating a balloon that has an adjustable, larger center diameter with fixed, smaller diameters at each end. These characteristics allow a single balloon to expand to multiple diameters, enabling the physician to perform interventional procedures in vessels of varying diameters and anatomical locations. In particular, the FOCAL technology enables cardiologists to incrementally increase the angioplasty balloon's center diameter during a procedure to enhance the effectiveness of the treatment in vessels that have uncertain or varying diameters or irregular plaque deposits. Use of conventional catheter technology in these situations may require multiple catheters to achieve a similar outcome. The FOCAL technology may also reduce the incidental damage to the artery wall adjacent to the lesion, as the therapeutic radial force is applied more accurately to the treatment site.

23

The Company's proprietary M(3) technology combines multiple membranes of polymeric balloon material to form a single balloon that enables the accurate delivery of drugs or contrast agents to the lesion or thrombus site. Drugs are utilized by cardiologists to reduce the occurrence of restenosis and acute reclosure, and to dissolve blood clots. Typically, therapeutic drug delivery is accomplished by means of an intravenous injection, a method that requires larger amounts of drug than is clinically required because the drug is diffused throughout the body. The accurate delivery of drugs to the treatment site may enhance the effectiveness of these pharmacological agents, thereby reducing the quantity of drug required to achieve an acceptable clinical outcome and potentially reducing the incidence of acute reclosure and restenosis. In addition, the Company has developed M(3) catheters with multiple inner lumens, providing the cardiologist with flexibility in drug treatment regimens. The multiple lumens of the catheter may also be used to deliver contrast media for angiographic viewing when advancing a catheter along a totally occluded vessel. Traditional catheters must be removed to inject contrast media into a total occlusion. Finally, the M(3) technology can be utilized to provide perfusion of blood during an interventional procedure. The interruption in blood flow caused by a conventional angioplasty balloon may cause tissue damage, heart attack or death, particularly if the balloon inflation required is of significant duration. Existing catheters that do not perfuse blood require cardiologists to inflate and deflate the balloon multiple times for shorter periods which may reduce the clinical effectiveness of the treatment.

STRATEGY

The Company's objective is to be a leader in the design, development and commercialization of clinically effective solutions for certain vascular diseases. While there can be no assurance that the Company will achieve this objective, following are the key elements of CVD's strategy.

Maintain Technological Leadership and Product Technology Advantages. CVD's strategy is to be a technological leader in the treatment of vascular diseases through product innovation. The Company believes that its products have significant performance advantages over alternative catheter technologies. The Company intends to maintain and advance its position of technology leadership through aggressive research, development and clinical testing programs. The Company owns five issued and four allowed U.S. patents related to key aspects of its catheter technologies and has applied for additional U.S. patents as well as foreign patent protection.

Market Products through Independent Distributors and a Direct Salesforce. The Company currently markets its products through a combination of independent distributors and a dedicated salesforce. The Company currently employs nine direct sales people who target the more densely-populated regions of the United States, and plans to significantly expand its direct sales force over the next eighteen months. CVD utilizes independent distributors internationally and in selected U.S. markets.

Establish Relationships with Clinical Opinion Leaders. The Company believes that establishing relationships with clinical opinion leaders in the field of interventional cardiology may raise the awareness of the clinical and cost benefits of the Company's products. CVD is currently conducting or planning three post-marketing clinical studies with certain of such leaders. In addition, the Company consults with certain cardiologists who assist the Company in ongoing product and technology development.

Target International Markets. CVD seeks to commercialize its products in those international markets where regulatory approval can be obtained more quickly than in the United States. This enables CVD to generate revenue more quickly from its product development efforts, to fund its operations and increase awareness of its products within the international interventional cardiology community.

Establish Strategic Partnerships. The Company attempts to identify and evaluate potential strategic relationships where such relationships may complement and expand the Company's research, development, sales and marketing capabilities. The Company believes that such strategic relationships may facilitate the market acceptance of the Company's products.

(1) Available only outside the United States due to patent restrictions.
(2) Not approved in the United States for stent delivery. The marketing of this product in the United States for such use will require the Company to obtain a PMA supplement approval. The Company is not currently seeking such approval.

FOCAL Catheters. The Company's FOCAL products have a catheter balloon that has an adjustable, larger center diameter and smaller, fixed, distal and proximal diameters. This characteristic provides increased utility in a variety of therapeutic treatments and anatomical locations. Existing uniform diameter catheters require cardiologists to use multiple balloons to treat vessels of varying diameters, resulting in unnecessary costs. In addition, the FOCAL catheters may deliver stents more effectively by focusing the radial deployment force on the stented section, rather than along the entire balloon, which may reduce the damage to the adjacent vessel.

25

M(3) Catheters. The Company's M(3) catheters offer cardiologists the ability to deliver drugs or contrast media to the treatment site accurately, and enable the perfusion of blood during angioplasty procedures. These capabilities may be combined on an interventional catheter to provide cardiologists the functionality of multiple catheters, in a single, cost-effective device. The accurate delivery of drugs to the treatment site may enhance the effectiveness of these pharmacological agents and may reduce the quantity of drug required to achieve an acceptable outcome. Drugs are utilized by cardiologists to reduce the occurrence of restenosis and acute reclosure, and to dissolve blood clots. Typically, therapeutic drug delivery is accomplished by means of an intravenous injection, a method that requires larger amounts of drug than is clinically required because the drug is diffused throughout the body. The Company's M(3) technology enables cardiologists to deliver drugs directly to the treatment site through a catheter's lumen, or interior channel. While CVD's M(3) site-specific drug delivery catheters are currently marketed internationally, they can only be used in the United States to administer drugs specifically approved by the FDA for administration by such catheters. The multiple lumens of the catheter may also be used to deliver contrast media for angiographic viewing when advancing the catheter along a totally occluded vessel. Traditional catheters must be removed to inject contrast media into a total occlusion. Finally, the M(3) technology can be utilized to provide perfusion of blood during an interventional procedure. This perfusion capability allows the balloon to be inflated for longer durations and reduces the number of inflations and deflations required in certain procedures, and may increase the clinical effectiveness of the treatment.

Vascular Access Products

The Company's vascular access products utilize patented technology to provide rapid, accurate access to the body's vascular system for guidewire and catheter entry. The principal current product, called the SmartNeedle, was acquired from ACS and is based on Doppler ultrasound technology. A miniaturized ultrasound chip is placed at the tip of a disposable ultrasonic probe which is then placed inside a conventional vascular access needle. The probe is then connected to a separate reusable monitor. Once placed in the body as a part of the access needle, the Doppler chip emits an audible signal which enables the physician to more accurately determine whether or not the needle resides in the proper location within the intended arterial or venous lumen. Once positioned properly, the probe is removed, leaving the conventional access needle in place within the artery or vein. Since introduction, the SmartNeedle's primary use has been in interventional cardiology and radiology procedures.

26

NEW PRODUCT DEVELOPMENT

The Company focuses its research and development efforts on utilizing the Company's proprietary processes and patented technologies to develop cost-effective products that address existing and emerging clinical demands. The Company's strategy is to refine its existing technologies and to enhance the performance of its existing product offerings, including efforts to make its FOCAL and M(3) products lower profile, more flexible and trackable, and operable at a broader range of inflation pressures. In addition, the Company is developing additional products utilizing combinations of its technologies that may provide cardiologists greater therapeutic applicability in a single device. The Company is also in the process of developing unique catheter designs intended to provide enhanced delivery of therapeutic radial force and pharmacological agents. The Company will be required to seek FDA approval for any new product and it is expected that some of these products will be subject to the PMA process. The Company's current new product development efforts are summarized in the table below.

The M(3) technology is being utilized in various experimental clinical programs to administer the site-specific delivery of therapeutic agents following angioplasty or stent delivery for the purpose of reducing or eliminating restenosis. The Company is also using M(3) technology in its MicroMembrane Radiation Therapy development program for restenosis prevention. This program is evaluating CVD's M(3) technology to more accurately deliver radioactive substances specifically to the treatment site.

27

TECHNOLOGY

The Company has developed proprietary material manufacturing processes that it has utilized to develop patented interventional catheters. Traditional balloon extrusion technology does not enable the combination of compliant and non-compliant materials, resulting in a catheter that can be inflated only to a uniform diameter. The Company's FOCAL technology bonds a membrane between compliant and non-compliant materials, resulting in a balloon with a large center diameter and smaller, fixed diameters at each end. The center compliant section of the FOCAL catheter enlarges predictably at a rate of 0.1mm per atmosphere of pressure when inflation pressures exceed six atmospheres. The ends of the balloon remain at their nominal diameters and do not expand with increased pressure. The FOCAL capability enables cardiologists to deliver stents or therapeutic radial force accurately to the treatment site, while minimizing the force applied to adjacent tissue. Conventional uniform diameter catheters may damage healthy vessel sections, as these sections receive as much radial force as do the diseased sites. It is widely believed that vessel wall damage may lead to acute reclosure of the vessel or restenosis.

The Company's M(3) technology creates a membrane by applying mechanical and radiation treatment to standard polymeric balloon material during the extrusion process. Microporous holes are then drilled in the resulting material by proprietary mechanical or laser drilling processes. CVD's M(3) technology also enables blood to flow through a coil lumen or inner shaft of the catheter, allowing perfusion to the distal vessels (those beyond the treatment site) during angioplasty or drug delivery. Prior to inflation, the balloon acts as a shaft for the distal portion of the catheter. Once the balloon is inflated, the cardiologist advances a coil into and through the inner lumen of the inflated balloon. The coil supports the balloon during balloon angioplasty or drug delivery and facilitates the perfusion of the distal vessels. The M(3) technology enables the Company to combine balloon angioplasty and perfusion capabilities on a single catheter in a profile comparable to standard balloon angioplasty catheters without perfusion capability. The Company believes that the M(3) technology also enables it to combine PTCA and perfusion capabilities on a single catheter with a lower profile than any currently marketed catheter with similar capabilities.

MANUFACTURING

With the exception of certain final assembly and sterilization procedures for those products designed to be sold only outside the United States, and the manufacture of those products which the Company has licensed to third parties, all of the Company's products are produced in its facilities in Irvine, California. The Company fabricates certain proprietary components, then assembles, inspects, tests and packages all components into finished products. By designing and assembling its catheter products, the Company believes it is better able to control quality and costs, limit third-party access to its proprietary technology, and manage manufacturing process enhancements and new product introductions. In addition, the Company purchases many standard and custom-built components from independent suppliers and subcontracts certain processes from independent vendors. Most of these components and processes are available from more than one vendor. However, certain manufacturing processes are currently performed by single vendors. While the Company believes that there are other vendors available to perform these processes, an interruption of performance by any of these vendors could have a material adverse effect on the Company's ability to manufacture its products until a new source of supply were qualified and, as a result, could have an adverse effect on the Company's business, financial condition and results of operations.

The Company's success will depend in part upon its ability to manufacture its products in compliance with ISO 9001, the FDA's GMP regulations, CDHS licensing and other regulatory requirements, in sufficient quantities and on a timely basis, while maintaining product quality and acceptable manufacturing costs. The Company began manufacturing certain of its products at its facilities in July 1995. Accordingly, the Company has very limited experience in manufacturing its products. In addition, the Company currently intends to introduce a significant number of new products in 1996. The Company has undergone and expects to continue to undergo regular GMP inspections in connection with the manufacture of its products at the Company's facilities. The Company's success will depend, among other things, upon its ability to efficiently manage the simultaneous manufacture of different products and to integrate the manufacture of new products with existing products. There can be no assurance that the Company will not encounter difficulties in scaling up production of new products, including problems involving production yields, quality control and assurance, component supply and shortages of qualified personnel. The Company's failure to successfully commence the

28

manufacturing of these new products, or to increase production volumes of new and existing products in a timely manner, would materially adversely affect the Company's business, financial condition and results of operations. Failure to increase production volumes in a timely or cost-effective manner or to maintain compliance with ISO 9001, GMP regulations, CDHS or other regulatory requirements could have a material adverse effect on the Company's business, financial condition and results of operations. See "Risk Factors -- Limited Manufacturing Experience."

MARKETING AND SALES

The Company's products are sold in the United States and international markets, principally Europe and Japan. However, certain of the Company's products are not available in each market due to regulatory and intellectual property restrictions. The Company currently sells its products through a combination of strategic partners, medical device distributors and nine direct sales personnel. The Company is a party to three agreements for the U.S. distribution of products incorporating its FOCAL and M(3) technologies. CVD also has distribution agreements with 18 companies covering 35 countries outside the United States and Japan. CVD distributes certain products in Japan through an exclusive distribution agreement with Fukuda. Sales of the Company's products through Fukuda accounted for 18% and 22% of the Company's revenue in 1995 and the first three months of 1996, respectively. In addition, sales to JJIS accounted for 12% of revenue in 1995. The Company intends to expand its sales and marketing capability and to distribute selected new products through strategic partnerships. See "Risk Factors -- Limited Marketing and Sales Resources; Dependence Upon Strategic Relationships."

In 1993, 1994, 1995 and the first three months of 1996, total export sales were $101,000, $970,000, $2,054,000 and $1,138,000, respectively, or approximately 80%, 83%, 59% and 64%, respectively, of total product sales. In 1993, 1994, 1995 and the first three months of 1996 sales to Europe accounted for $101,000, $255,000, $1,179,000 and $411,000, respectively; sales to Japan represented $0, $715,000, and $744,000 and $455,000, respectively; and sales to Latin America represented $0, $0, $131,000 and $272,000, respectively. The Company expects to continue to derive significant revenue from international sales and therefore a significant portion of the Company's revenues will continue to be subject to the risks associated with international sales, including economic or political instability, shipping delays, changes in applicable regulatory policies, inadequate protection of intellectual property, fluctuations in foreign currency exchange rates and various trade restrictions, all of which could have a significant impact on the Company's ability to deliver products on a competitive and timely basis. Future imposition of, or significant increases in the level of, customs duties, export quotas or other trade restrictions, could have an adverse effect on the Company's business, financial condition and results of operation. In foreign countries, the Company's products are subject to a wide variety of governmental review and certification. The regulation of medical devices, particularly in the European Community, continues to expand and there can be no assurance that new laws or regulations will not have an adverse effect on the Company. See Note 1 of Notes to Financial Statements. See "Risk Factors -- Dependence Upon International Sales."

POST-MARKETING CLINICAL STUDIES

The Company has completed the clinical trials required for FDA approval of those products which are marketed in the United States. In addition to those trials, the Company is also sponsoring two controlled, randomized, multicenter clinical studies in the United States and overseas to continue to evaluate the clinical and economic value of its core technologies. Data from these studies are being accumulated and analyzed to support the marketing of the Company's current products.

In a Comparative Performance and Pathological Study conducted by the Division of Cardiology at the University of Texas Department of Medicine, the Company's FACT catheter was compared with conventional PTCA catheters from other leading manufacturers in an animal study. The investigators concluded that the use of the FACT catheter resulted in reduced arterial damage without reduction in catheter performance as determined by catheter preparation, trackability, pushability, inflation/deflation and angiographic visualization.

A second study is comparing the FOCAL PTCA catheter with conventional PTCA catheters. The FOCAL Lesion Expansion Optimizes Results Study ("FLEXOR Study") will evaluate the efficacy of FOCAL technology in improving clinical results following angioplasty procedures. Success will be measured

29

based on the ability of FOCAL technology to improve the minimal lumen diameter ("MLD") of the arterial opening, to increase safety and to reduce the number of catheters necessary for PTCA procedures. Results will be interpreted in light of any procedure-related vascular complications, restenosis and occurrences of other major clinical adverse cardiac events. MLD is a commonly-used measurement of the ability of a therapeutic tool to open a blocked artery and reestablish required blood flow. The FLEXOR Study protocol is being finalized and is expected to begin during the third quarter of 1996. Completion is expected in 1997.

Certain of the Company's products which utilize FOCAL technology have received FDA approval for PTCA and PTA indications. However, none of these products has received FDA approval for use in stent delivery. An investigator-controlled study is currently testing the Company's FOCAL technology with respect to stent implantation. The Optimal Stent Implantation Study ("OSTI-2 Study") is evaluating the ability of stent delivery with FOCAL technology compared with conventional delivery techniques to reduce acute outcomes and restenosis rates. The study is being conducted using two patient subgroups of approximately 100 patients each divided according to vessel size. In the first group, stent delivery is being evaluated in vessels greater than three millimeters in diameter; in the second group stent delivery is being evaluated in vessels less than three millimeters in diameter. Each subgroup presents different clinical issues related to stent delivery and the OSTI-2 Study protocol is evaluating the efficacy of FOCAL technology in each subgroup. The OSTI-2 Study began in February 1996 and is expected to be completed in 1997.

The Company also intends to sponsor additional studies from time to time to assess the value of, and to expand clinical indications of, its existing and new technologies. The Company is planning a clinical study to expand the clinical uses of its FOCAL technology catheters to include balloon dilatation of previously deployed stents in order to properly implant the stent in the arterial wall. The Company is finalizing the clinical protocol for this study and expects to begin this study prior to the end of 1996. This study will include approximately 100 patients and is expected to be completed in 1997.

STRATEGIC RELATIONSHIPS

The Company evaluates on an ongoing basis potential strategic relationships with corporate and other partners where such relationships may complement and expand CVD's research, development, sales and marketing capabilities. The Company is currently a party to four such agreements, described below.

Advanced Cardiovascular Systems, Inc.. In January 1995, the Company entered into a license agreement with ACS. The parties subsequently confirmed their understanding with respect to certain matters in a second agreement dated March 4, 1996 (collectively, the "ACS Agreements"). Under the ACS Agreements, the Company acquired certain rights to ACS' SmartNeedle technology, subject to the payment of certain royalties. ACS was granted the option to acquire the exclusive worldwide rights to certain CVD perfusion technology, which ACS exercised on February 14, 1996. As a result, ACS has an exclusive worldwide right to develop, manufacture and market the Company's MAC I product line. In exchange for this technology, ACS is obligated to make milestone and minimum annual royalty payments to CVD, and also has certain obligations to develop and market the technology. In addition, in the event that CVD develops a product which combines coronary balloon angioplasty, perfusion and drug delivery technology on the same catheter, ACS will have certain rights to license such product. The ACS Agreements may be terminated upon 60 days notice in the event of a breach by the other party, subject to the breaching party's right to cure, or by ACS upon 30 days notice without cause.

SCIMED Life Systems, Inc. The Company has entered into a Stock Purchase and Technology License Agreement, dated September 10, 1994, with SCIMED (the "SCIMED Agreement"). Pursuant to the SCIMED Agreement, SCIMED purchased a 19% equity position in the Company. SCIMED was also granted an exclusive worldwide license to certain combined site-specific drug delivery and coronary angioplasty technology, including the Company's Transport products, for use in the cardiovascular field in exchange for license and royalty fees. The SCIMED Agreement also requires CVD to provide certain technical assistance and to perform additional research and development relating to the licensed technology in exchange for fees and reimbursement of expenses. In the event that CVD's SCIMED-funded research and development efforts result in improvements to the licensed technology, SCIMED will have an exclusive worldwide license to the technology in the cardiovascular field and a non-exclusive license outside the cardiovascular field, both of which are subject to the payment of royalties. The SCIMED Agreement may be

30

terminated in the event of breach on 90 days notice by the non-breaching party (or on 30 days notice in certain limited circumstances) or by SCIMED upon 180 days notice.

Fukuda Denshi Co., Ltd. The Company has entered into a Distribution Agreement, dated May 28, 1993, with Fukuda Denshi Co., Ltd. (the "Fukuda Agreement"), whereby Fukuda serves as CVD's exclusive distributor for certain of the Company's products in Japan. In exchange for this exclusive distributorship, Fukuda paid a fee to CVD in addition to payments owing upon the purchase of the products. Fukuda also agreed to undertake all necessary clinical trials to obtain approval from Japanese regulatory authorities for the sale of the products in Japan. Fukuda's purchases under the Fukuda Agreement are subject to certain minimum requirements. The initial term of the Fukuda Agreement expires on May 31, 1998, subject to a five-year extension. The Fukuda Agreement may also be terminated in the event of breach upon 90 days notice by the non-breaching party. In July 1995 and May 1996, the distribution agreement with Fukuda was amended to grant Fukuda exclusive distribution rights to additional CVD products. Under these amendments, the Company received a $750,000 investment which is convertible by Fukuda into Common Stock upon the consummation of this offering (the "Convertible Obligation").

EndoSonics Corporation. The Company has entered into a license agreement with EndoSonics, dated December 22, 1995 (the "EndoSonics Agreement"), pursuant to which CVD granted EndoSonics the non-exclusive, royalty-free right to CVD's FOCAL technology for the development and sale of a combined FOCAL/Ultrasound product. In exchange, CVD received the non-exclusive, royalty-free right to submit PMA supplement applications utilizing an EndoSonics PMA as a reference and to manufacture and distribute CVD products as a supplement to the EndoSonics PMA. The EndoSonics Agreement may be terminated in the event of breach upon 60 days notice by the non-breaching party, subject to the breaching party's right to cure. In the event of termination, the Company would be prohibited from submitting new PMA supplements referencing the EndoSonics PMA and would be required to seek independent FDA approval for such products, which would have a material adverse effect on the Company's business, financial condition and results of operations. In addition, EndoSonics recently purchased 400,000 shares of CVD's Series B Preferred Stock for a purchase price of $8,000,000, which will convert into 800,000 shares of Common Stock upon the consummation of this offering. See "Certain Transactions -- Relationship with EndoSonics Corporation."

PATENTS AND PROPRIETARY INFORMATION

The Company's policy is to protect its proprietary position by, among other methods, filing U.S. and foreign patent applications to protect technology, inventions and improvements that are important to the development of its business. The Company has five issued and four allowed U.S. patents covering certain aspects of its catheter technology and licenses additional patents relating to the vascular access technology. Eleven additional patent applications have been submitted to the U.S. Patent Office and additional patent applications have been submitted to international agencies for review. No assurance can be given that pending patent applications will be approved, or that any issued patents will provide competitive advantages for the Company's products, or that they will not be challenged or circumvented by competitors.

The interventional cardiovascular market in general and the balloon angioplasty catheter market (including the type of catheters offered by CVD) in particular have been characterized by substantial litigation regarding patent and other intellectual property rights. Although the Company believes that its products do not infringe other parties' patents and proprietary rights, there can be no assurance that its products do not infringe such patents or rights. In the event that any such third-parties assert claims against the Company for patent infringement and such patents are upheld as valid and enforceable, the Company could be prevented from utilizing the subject matter claimed in such patents, or would be required to obtain licenses from the owners of any such patents or redesign its products or processes to avoid infringement. There can be no assurance that such licenses would be available or, if available, would be so on terms acceptable to the Company or that the Company would be successful in any attempt to redesign its products or processes to avoid infringement. In addition, foreign intellectual property laws may not provide protection commensurate with that provided by U.S. intellectual property laws, and there can be no assurance that foreign intellectual property laws will adequately protect the Company's intellectual property rights abroad. The Company also relies on trade secrets and proprietary technology and enters into confidentiality and non-disclosure agree-

31

ments with its employees, consultants and advisors. There can be no assurance that the confidentiality of such trade secrets or proprietary information will be maintained by employees, consultants, advisors or others, or that the Company's trade secrets or proprietary technology will not otherwise become known or be independently developed by competitors in such a manner that the Company has no practical recourse. Litigation may be necessary to defend against claims of infringement or invalidity, to enforce patents issued to the Company or to protect trade secrets. There can be no assurance that any such litigation would be successful. Any litigation could result in substantial costs to, and diversion of resources by, the Company and its officers, which would have a material adverse effect on its business, financial condition and results of operations. See "Risk Factors -- Reliance on Patents and Proprietary Technology; Risk of Patent Infringement."

COMPETITION

The Company believes that the primary competitive factors in the market for interventional cardiology devices are: clinical effectiveness, product safety, catheter size, flexibility and trackability, ease of use, reliability, price and availability of third party reimbursement. In addition, a company's distribution capability and the time in which products can be developed and receive regulatory approval are important competitive factors. The Company believes it competes favorably with respect to the foregoing factors. The Company also believes that its competitive position is dependent upon its ability to continue to develop innovative new catheter technologies and obtain rapid regulatory approval.

Competition in the market for devices used in the treatment of cardiovascular and peripheral vascular disease is intense, and is expected to increase. The interventional cardiology market is characterized by rapid technological innovation and change, and the Company's products could be rendered obsolete as a result of future innovations. The Company's catheters compete or will compete with catheters marketed by a number of manufacturers, including ACS, SCIMED, JJIS and Cordis Corporation, subsidiaries of Johnson & Johnson, Medtronic, Inc., C.R. Bard, Inc. and Schneider USA, a subsidiary of Pfizer, Inc. Such companies have significantly greater financial, management and other resources, established market positions, and significantly larger sales and marketing organizations than does the Company. The Company also faces competition from manufacturers of other catheter-based atherectomy devices, vascular stents and pharmaceutical products intended to treat vascular disease. In addition, the Company believes that many of the purchasers and potential purchasers of the Company's products prefer to purchase catheter products from a single source. Accordingly, many of the Company's competitors, because of their size and range of product offerings, have a competitive advantage over the Company. There can be no assurance that the Company's competitors will not succeed in developing or marketing technologies and products that are more clinically effective or cost effective than any that are being marketed or developed by the Company, or that such competitors will not succeed in obtaining regulatory approval for introducing or commercializing any such products prior to the Company. See "Risk Factors -- Significant Competition."

THIRD-PARTY REIMBURSEMENT

In the United States, the Company's products are purchased primarily by medical institutions, which then bill various third-party payors, such as Medicare, Medicaid, and other government programs and private insurance plans, for the health care services provided to patients. Government agencies, private insurers and other payors determine whether to provide coverage for a particular procedure and reimburse hospitals for medical treatment at a fixed rate based on the diagnosis-related group ("DRG") established by the U.S. HCFA. The fixed rate of reimbursement is based on the procedure performed, and is unrelated to the specific devices used in that procedure. If a procedure is not covered by a DRG, payors may deny reimbursement. In addition, some payors may deny reimbursement if they determine that the device used in a treatment was unnecessary, inappropriate or not cost-effective, experimental or used for a non-approved indication. Reimbursement of interventional procedures utilizing the Company's products is currently covered under a DRG. There can be no assurance that reimbursement for such procedures will continue to be available, or that future reimbursement policies of payors will not adversely affect the Company's ability to sell its products on a profitable basis. Failure by hospitals and other users of the Company's products to obtain reimbursement from

32

third-party payors, or changes in government and private third-party payors' policies toward reimbursement for procedures employing the Company's products, would have a material adverse effect on the Company's business, financial condition and results of operations. See "Risk Factors -- Limitations on Third-Party Reimbursement."

GOVERNMENT REGULATION

The manufacturing and marketing of the Company's products are subject to extensive and rigorous government regulation in the United States and in other countries. The Company believes that its success will be significantly dependent upon commercial sales of improved versions of its catheter products. The Company will not be able to market these new products in the United States unless and until the Company obtains approval or clearance from the FDA. Foreign and domestic regulatory approvals, if granted, may include significant limitations on the indicated uses for which a product may be marketed.

If a medical device manufacturer can establish that a newly developed device is "substantially equivalent" to a legally marketed Class I or Class II device, or to a Class III device that the FDA has not called for a PMA, the manufacturer may seek clearance from the FDA to market the device by filing a premarket notification with the FDA under Section 510(k) of the Federal Food, Drug, and Cosmetic Act. All of the 510(k) clearances received for the Company's catheters were based on substantial equivalence to legally marketed devices. There can be no assurance that 510(k) clearance for any future product or significant modification of an existing product will be granted or that the process will not be unduly lengthy. In addition, if the FDA has concerns about the safety or effectiveness of any of the Company's products, it could act to withdraw approval or clearances of those products or request that the Company present additional data. Any such actions would have a material adverse effect on the Company's business, financial condition and results of operations.

If substantial equivalence cannot be established, or if the FDA determines that the device or the particular application for the device requires a more rigorous review to assure safety and effectiveness, the FDA will require that the manufacturer submit a PMA application that must be reviewed and approved by the FDA prior to sales and marketing of the device in the United States. The PMA process is significantly more complex, expensive and time consuming than the 510(k) clearance process and always requires the submission of clinical data. It is expected that certain of the Company's products under development will be subject to this PMA process. The Company currently has a non-exclusive, royalty-free right to submit PMA supplement applications utilizing an EndoSonics PMA as a reference and to manufacture and distribute CVD products as a supplement to the EndoSonics PMA. This agreement may be terminated in the event of breach upon 60 days notice by the non-breaching party, subject to the breaching party's right to cure. In the event of termination, the Company would be prohibited from submitting new PMA supplements referencing the EndoSonics PMA and would be required to seek independent FDA approval for any such products, which would have a material adverse effect on the Company's business, financial condition and results of operations.

The Company is also required to register as a medical device manufacturer with the FDA and maintain a license with certain state agencies, such as the CDHS. As such, the Company is inspected on a routine basis by both the FDA and the CDHS for compliance with GMP regulations. These regulations require that the Company manufacture its products and maintain related documentation in a prescribed manner with respect to manufacturing, testing and control activities. The Company has also undergone and expects to continue to undergo regular GMP inspections in connection with the manufacture of its products at the Company's facilities. Further, the Company is required to comply with various FDA requirements for labeling. The Medical Device Reporting laws and regulations require that the Company provide information to the FDA on deaths or serious injuries alleged to have been associated with the use of its devices, as well as product malfunctions that would likely cause or contribute to death or serious injury if the malfunction were to recur. In addition, the FDA prohibits an approved device from being marketed for unapproved applications. CVD has received FDA approval to market the FACT catheters, which utilize the FOCAL technology, for coronary balloon angioplasty. These catheters are marketed outside the United States for use in stent deployment. However, without specific FDA approval for stent deployment, these catheters may not be marketed by the Company in the United States for such use.

33

Failure to comply with applicable regulatory requirements can, among other consequences, result in fines, injunctions, civil penalties, suspensions or loss of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution. In addition, government regulations may be established in the future that could prevent or delay regulatory clearance or approval of the Company's products. Delays in receipt of clearances or approvals, failure to receive clearances or approvals or the loss of previously received clearances or approvals would have a material adverse effect on the Company's business, financial condition and results of operations.

The Company is also subject to other federal, state and local laws, regulations and recommendations relating to safe working conditions, laboratory and manufacturing practices. The extent of government regulation that might result from any future legislation or administrative action cannot be accurately predicted. Failure to comply with regulatory requirements could have a material adverse effect on the Company's business, financial condition and results of operations.

International sales of the Company's products are subject to the registration requirements of each country. The regulatory review process varies from country to country and may in some cases require the submission of clinical data. The Company typically relies on its distributors in such foreign countries to obtain the requisite regulatory approvals. There can be no assurance, however, that such approvals will be obtained on a timely basis or at all. In addition, the FDA must approve the export to certain countries of devices that require a PMA but are not yet approved domestically.

The Company is in the process of implementing policies and procedures which are intended to allow the Company to receive ISO 9001 certification of its quality system. The ISO 9000 series of standards for quality operations has been developed to ensure that companies know the standards of quality to which they must adhere to receive certification. The European Union has promulgated rules which require that medical products receive by mid-1998 the right to affix the CE mark, an international symbol of adherence to quality assurance standards and compliance with applicable European medical device directives. ISO 9001 certification is one of the CE mark certification requirements. Failure to receive the right to affix the CE mark will prevent the Company from selling its products in member countries of the European Union. While the Company is in the process of becoming ISO 9001 certified, there can be no assurance that the Company will be successful in meeting these or any other certification requirements on a timely basis, or at all.

PRODUCT LIABILITY

The Company faces the risk of financial exposure to product liability claims. The Company's products are often used in situations in which there is a high risk of serious injury or death. Such risks will exist even with respect to those products that have received, or in the future may receive, regulatory approval for commercial sale. The Company is currently covered under EndoSonics' product liability insurance policy with coverage limits of $2.0 million per occurrence and $2.0 million per year in the aggregate. However, this coverage will terminate when the Company ceases to be a majority-owned subsidiary of EndoSonics. Accordingly, following this offering, the Company expects to obtain product liability insurance with similar coverage limits. There can be no assurance that the Company's product liability insurance is adequate or that such insurance coverage will remain available at acceptable costs. There can be no assurance that the Company will not incur significant product liability claims in the future. A successful claim brought against the Company in excess of its insurance coverage could have a material adverse effect on the Company's business, financial condition and results of operations. Additionally, adverse product liability actions could negatively affect the reputation and sales of the Company's products and the Company's ability to obtain and maintain regulatory approval for its products and substantially divert the time and effort of management away from the Company's operations.

EMPLOYEES

As of April 30, 1996, the Company had 92 employees, including 56 in manufacturing, 12 in research, development and regulatory affairs, 15 in sales and marketing, 5 in administration and 4 in quality assurance. The Company believes that the success of its business will depend, in part, on its ability to attract and retain qualified personnel. The Company believes it has good relations with its employees.

34

PROPERTIES

Currently, the Company leases facilities aggregating approximately 22,000 square feet in Irvine, California under lease agreements which expire beginning in 1997. The Company believes that its facilities are adequate to meet its requirements through 1997.

(1) Each of the options listed in the table was granted under the Company's 1995 Stock Option Plan. Each such option will be incorporated into the 1996 Stock Option/Stock Issuance Plan.

(2) Based upon options granted for an aggregate of 957,000 shares to employees in 1995, including the Named Officer.

(3) The exercise price may be paid in cash, in shares of the Company's Common Stock valued at fair market value on the exercise date or through a cashless exercise procedure involving a same-day sale of the purchased shares. The Company may also finance the option exercise by loaning the optionee sufficient funds to pay the exercise price for the purchased shares, together with any federal and state income tax liability incurred by the optionee in connection with such exercise. The Compensation Committee of the Board of Directors, as the Plan Administrator of the Company's 1996 Stock Option/Stock Issuance Plan, has the discretionary authority to reprice the options through the cancellation of those options and the grant of replacement options with an exercise price based on the fair market value of the option shares on the grant date.

(4) The 5% and 10% assumed annual rates of compounded stock price appreciation are mandated by rules of the Securities and Exchange Commission. There can be no assurance provided to any executive officer or any other holder of the Company's securities that the actual stock price appreciation over the option term will be at the assumed 5% and 10% levels or at any other defined level. Unless the market price of the Common Stock appreciates over the option term, no value will be realized from the option grants made to the executive officers.

(5) The option was granted on May 15, 1995 and has a maximum term of ten years measured from the grant date, subject to earlier termination upon the optionee's termination of service with the Company. Each option is immediately exercisable subject to a repurchase right in favor of the Company which lapses in a series of annual and monthly installments over the optionee's period of service with the Company. The Company's repurchase right lapses as to 25% of the option shares upon the optionee's completion of one year of service measured from November 21, 1994 and as to the balance of the option shares in a series of successive equal monthly installments upon the optionee's completion of each additional month of service over the next 36 months thereafter.

(6) The option was granted on December 19, 1995 and has a maximum term of ten years measured from the grant date, subject to earlier termination upon the optionee's termination of service with the Company. Each option is immediately exercisable subject to a repurchase right in favor of the Company which lapses in a series of annual and monthly installments over the optionee's period of service with the Company. The Company's repurchase right lapses as to 25% of the option shares upon the optionee's completion of one year of service measured from the grant date and as to the balance of the option shares in a series of successive equal monthly installments upon the optionee's completion of each additional month of service over the next 36 months thereafter.

(1) Options are immediately exercisable for all the option shares, but any shares purchased under the options will be subject to repurchase by the Company at the original exercise price per share upon the optionee's cessation of service. Shares subject to repurchase are shown under the "Unexercisable" column.

(2) Based on the fair market value of the Company's Common Stock at year-end, $1.50 per share (as determined by the Company's Board of Directors), less the exercise price payable for such shares.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

The Compensation Committee of the Company's Board was formed in May 1996, and the members of the Compensation Committee are Messrs. Davis and Dann. Neither of these individuals was at any time during the fiscal year ended December 31, 1995, or at any other time, an officer or employee of the Company. No member of the Compensation Committee of the Company serves as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of the Company's Board of Directors or Compensation Committee.

1996 STOCK OPTION/STOCK ISSUANCE PLAN

The Company's 1996 Stock Option/Stock Issuance Plan (the "1996 Plan") is intended to serve as the successor equity incentive program to the Company's 1995 Stock Option Plan (the "Predecessor Plan"). The 1996 Plan was adopted by the Board of Directors and approved by the stockholders on May 1, 1996, (the "Effective Date"). Under the 1996 Plan, 1,200,000 shares of Common Stock have been authorized for issuance. This share reserve is comprised of the shares which remained available for issuance under the Predecessor Plan as of the Effective Date, including the shares subject to outstanding options thereunder. Those outstanding options will be incorporated into the 1996 Plan on the Effective Date, and no further option grants will be made under the Predecessor Plan. The incorporated options will continue to be governed by their existing terms, unless the Plan Administrator elects to extend one or more features of the 1996 Plan to those options. However, except as otherwise noted below, the outstanding options under the Predecessor Plan contain substantially the same terms and conditions specified below for the Discretionary Option Grant Program in effect under the 1996 Plan. In no event may any one participant in the 1996 Plan receive option grants or direct stock issuances for more than 800,000 shares in the aggregate over the term of the Plan.

The 1996 Plan is divided into three separate components: (i) the Discretionary Option Grant Program under which eligible individuals may, at the discretion of the Plan Administrator, be granted options to purchase shares of Common Stock at an exercise price not less than 85% of their fair market value on the grant date, (ii) the Stock Issuance Program under which such individuals may, in the Plan Administrator's discretion, be issued shares of Common Stock directly, through the purchase of such shares at a price not less than 85% of their fair market value at the time of issuance or as a bonus tied to the performance of services and (iii) the Automatic Option Grant Program under which option grants will automatically be made at periodic intervals to eligible non-employee Board members to purchase shares of Common Stock at an exercise price equal to 100% of their fair market value on the grant date.

The Discretionary Option Grant Program and the Stock Issuance Program will be administered by the Compensation Committee. The Compensation Committee as Plan Administrator will have complete discretion to determine which eligible individuals are to receive option grants or stock issuances, the time or times

40

when such option grants or stock issuances are to be made, the number of shares subject to each such grant or issuance, the status of any granted option as either an incentive stock option or a non-statutory stock option under the Federal tax laws, the vesting schedule to be in effect for the option grant or stock issuance and the maximum term for which any granted option is to remain outstanding.

Under the 1996 Plan, upon an acquisition of the Company by merger or asset sale or a hostile take-over of the Company, each outstanding option and unvested stock issuance will be subject to accelerated vesting under certain circumstances. The options granted under the Predecessor Plan will be assumed or replaced in a merger or asset sale but do not include any acceleration provisions in connection with a merger or asset-sale or upon a hostile take-over, although such options may be accelerated at the discretion of the Plan Administrator.

Stock appreciation rights are authorized for issuance under the Discretionary Option Grant Program which provide the holders with the election to surrender their outstanding options for an appreciation distribution from the Company equal to the excess of (i) the fair market value of the vested shares of Common Stock subject to the surrendered option over (ii) the aggregate exercise price payable for such shares. Such appreciation distribution may be made in cash or in shares of Common Stock. No stock appreciation rights exist with respect to options currently outstanding under the Predecessor Plan.

The Plan Administrator has the authority to effect the cancellation of outstanding options under the Discretionary Option Grant Program (including options incorporated from the Predecessor Plan) in return for the grant of new options for the same or different number of option shares with an exercise price per share based upon the fair market value of the Common Stock on the new grant date.

Under the Automatic Option Grant Program, each individual serving as a non-employee Board member on the date the Underwriting Agreement for this offering is executed will receive an option grant on such date for 5,000 shares of Common Stock, provided such individual has not otherwise been in the prior employ of the Company. Each individual who first becomes a non-employee Board member thereafter will receive a 5,000-share option grant on the date such individual joins the Board provided such individual has not been in the prior employ of the Company. In addition, at each Annual Stockholders Meeting held after the date of this offering, each individual who is to continue to serve as a non-employee Board after the meeting will receive an additional option grant to purchase 5,000 shares of Common Stock whether or not such individual has been in the prior employ of the Company.

Each automatic grant will have a term of 10 years, subject to earlier termination following the optionee's cessation of Board service. Each automatic option will be immediately exercisable; however, any shares purchased upon exercise of the option will be subject to repurchase should the optionee's service as a non-employee Board member cease prior to vesting in the shares. The initial 5,000-share grant will vest in four equal and successive annual installments over the optionee's period of Board service. Each additional annual 5,000-share grant will vest upon the optionee's completion of one year of Board service measured from the grant date. However, each outstanding option will immediately vest upon (i) certain changes in the ownership or control of the Company or (ii) the death or disability of the optionee while serving as a Board member.

The Board may amend or modify the 1996 Plan at any time. The 1996 Plan will terminate on April 30, 2006, unless sooner terminated by the Board.

EMPLOYEE STOCK PURCHASE PLAN

The Company's Employee Stock Purchase Plan (the "Purchase Plan") was adopted by the Board of Directors and approved by the stockholders on May 1, 1996. The Purchase Plan is designed to allow eligible employees of the Company and participating subsidiaries to purchase shares of Common Stock, at semi- annual intervals, through their periodic payroll deductions under the Purchase Plan, and a reserve of 200,000 shares of Common Stock has been established for this purpose.

The Purchase Plan will be implemented in a series of successive offering periods, each with a maximum duration of twenty-four months. The initial offering period will begin on the day the Underwriting Agreement is executed based on the initial public offering price and will end on the last business day in July 1998. Each offering period will be comprised of successive purchase intervals, each of a duration of six months. However,

41

the first purchase interval under the initial offering period may be of a duration in excess of six months. Shares of Common Stock will be purchased for each participant at the end of each purchase interval during the offering period. If the fair market value of the Common Stock on any purchase date in the offering period is less than the fair market value of the Common Stock at the start of the offering period, then that offering period will terminate and a new offering period will automatically commence on the next business day following that purchase date.

Payroll deductions may not exceed 10% of base salary for each purchase interval. The purchase price per share will be 85% of the lower of (i) the fair market value of the Common Stock on the participant's entry date into the offering period or (ii) the fair market value on the semi-annual purchase date. In no event may any participant purchase more than 950 shares of Common Stock on any purchase date.

The Board may terminate the Purchase Plan at any time. The Purchase Plan will terminate in all events on the last business day in July 2006.

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS

The Company's Certificate of Incorporation limits the liability of directors to the maximum extent permitted by Delaware law. Delaware law provides that a director of a corporation will not be personally liable for monetary damages for breach of such individual's fiduciary duties as a director except for liability (i) for any breach of such director's duty of loyalty to the corporation, (ii) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) for unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law, or (iv) for any transaction from which a director derives an improper personal benefit.

The Company's Bylaws provide that the Company will indemnify its directors and may indemnify its officers, employees and other agents to the full extent permitted by law. The Company believes that indemnification under its Bylaws covers at least negligence and gross negligence on the part of an indemnified party and permits the Company to advance expenses incurred by an indemnified party in connection with the defense of any action or proceeding arising out of such party's status or service as a director, officer, employee or other agent of the Company upon an undertaking by such party to repay such advances if it is ultimately determined that such party is not entitled to indemnification.

The Company has entered into separate indemnification agreements with each of its directors. These agreements require the Company, among other things, to indemnify such director against expenses (including attorneys's fees), judgments, fines and settlements (collectively, "Liabilities") paid by such individual in connection with any action, suit or proceeding arising out of such individual's status or service as a director of the Company (other than Liabilities arising from willful misconduct or conduct that is knowingly fraudulent or deliberately dishonest) and to advance expenses incurred by such individual in connection with any proceeding against such individual with respect to which such individual may be entitled to indemnification by the Company.

The Company believes that its Certificate of Incorporation and Bylaw provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers. At present the Company is not aware of any pending litigation or proceeding involving any director, officer, employee or agent of the Company where indemnification will be required or permitted. The Company is not aware of any threatened litigation or proceeding that might result in a claim for such indemnification.

EMPLOYMENT CONTRACTS AND CHANGE OF CONTROL ARRANGEMENTS

The Company does not presently have any employment contracts in effect with any of its executive officers.

The Compensation Committee as Plan Administrator of the 1996 Plan will have the authority to provide for the accelerated vesting of the shares of Common Stock subject to outstanding options held by the Chief Executive Officer and any other executive officer or the shares of Common Stock subject to direct issuances held by such individual, in connection with certain changes in control of the Company or the subsequent termination of the officer's employment following the change in control event.

CERTAIN TRANSACTIONS

RELATIONSHIP WITH ENDOSONICS CORPORATION

On June 15, 1992, EndoSonics acquired a 40% interest in CVD in exchange for $568,000 in cash. Upon completion of this investment, EndoSonics' President and Chief Executive Officer owned a 19% equity interest in CVD and served as Chairman of the Board. Pursuant to an Agreement and Plan of Reorganization between EndoSonics and CVD signed on June 9, 1993, EndoSonics acquired all of the outstanding capital stock of CVD in exchange for $335,000 in cash and 250,000 shares of EndoSonics' Common Stock with an aggregate market value of $1,563,000. Pursuant to the terms of the Agreement and Plan of Reorganization, in June 1995, EndoSonics became obligated to issue 50,000 shares of its Common Stock with an aggregate market value of $488,000, to the former shareholders of CVD because the market price of EndoSonics' stock did not exceed a specified price for a specified period during the two-year period following the acquisition. On March 29, 1996, EndoSonics acquired 400,000 shares of Series B Preferred Stock for a purchase price of $8,000,000, which will convert into 800,000 shares of Common Stock upon the consummation of this offering.

During 1994 and 1995, EndoSonics manufactured certain of the Company's catheter products. Total purchases from EndoSonics during 1994 and 1995 amounted to $0.8 million and $0.2 million, respectively. In addition, during 1994 EndoSonics performed certain billing and collection services for the Company in return for a fee per invoice which amounted to $10,000. In addition, since August 1993, certain of EndoSonics' corporate expenses, including Mr. Henson's salary, were paid by EndoSonics and accounting, cash management and other administrative services were performed by EndoSonics. Pursuant to this arrangement, the Company paid EndoSonics an aggregate of $290,000, $340,000, $54,000 and $48,000 for 1993, 1994, 1995 and the three months ended March 31, 1996, respectively. In addition, EndoSonics paid Mr. Henson's bonus for 1995. See "Management -- Executive Compensation."

The Company has entered into a license agreement with EndoSonics, dated December 22, 1995 (the "EndoSonics Agreement"), pursuant to which CVD granted EndoSonics the non-exclusive, royalty-free right to CVD's FOCAL technology for the development and sale of a combined FOCAL/Ultrasound product. In exchange, CVD received the non-exclusive, royalty-free right to submit PMA supplement applications utilizing an EndoSonics PMA as a reference and to manufacture and distribute CVD products as a supplement to the EndoSonics PMA. The EndoSonics Agreement may be terminated in the event of breach upon 60 days notice by the non-breaching party, subject to the breaching party's right to cure. In addition, EndoSonics recently purchased 400,000 shares of CVD's Series B Preferred Stock for a purchase price of $8,000,000, which will convert into 800,000 shares of Common Stock upon the consummation of this offering.

CVD and EndoSonics will enter into certain agreements for the purpose of defining the ongoing relationship between the two companies. EndoSonics owned approximately 84% of the outstanding voting capital stock of CVD prior to the offering made hereby and will own approximately 49% of CVD's Common Stock after the offering. Accordingly, these agreements are not the result of arm's-length negotiations between independent parties.

Prior to the completion of this offering, CVD and EndoSonics will enter into a Tax Allocation Agreement that will provide, among other things, for (i) the allocation of tax liabilities and adjustments thereto as between the business of the Company and other businesses conducted by EndoSonics and its affiliates related to periods in which the Company is includable in consolidated federal income tax returns filed by EndoSonics, (ii) the allocation of responsibility for filing tax returns and (iii) the conduct of and responsibility for taxes owed in connection with tax audits and various related matters, as described below.

EndoSonics will agree to indemnify CVD for any federal and state income tax liability arising out of any audit with respect to periods ending prior to the closing of the offering hereby and for which CVD was included in EndoSonics' consolidated federal income tax return or a state unitary or combined return. In addition, with respect to periods for which CVD is included in EndoSonics' federal consolidated or state unitary tax return, EndoSonics shall control the filing of such returns and the conduct of any audits thereof. With respect to periods following the closing of this offering, the Company will file its own federal income tax return and will not be included in EndoSonics' federal return. The Company will initially be included in

43

certain unitary or combined returns for state tax purposes. To the extent this occurs, this agreement generally will treat the Company as a separate taxpayer and will charge the Company with its separate tax return liability.

EndoSonics and CVD will enter into a Stockholder Agreement providing that all transactions between the Company and EndoSonics or any affiliate of EndoSonics must be approved by a special committee of CVD's Board of Directors comprised of two directors who are not officers, directors, employees or affiliates of EndoSonics. The members of this committee are Mitchell Dann and Gerard von Hoffmann. No transactions between the Company and EndoSonics are currently contemplated. During the effective term of the Agreement, EndoSonics may not vote to eliminate from the Company's Certificate of Incorporation provisions requiring cumulative voting for the election of directors. The provisions of the Agreement become effective upon the consummation of the offering made hereby and terminate on the earlier of seven years from the date of the Agreement or on the date EndoSonics beneficially owns less than 25% of CVD's Common Stock.

EndoSonics has informed the Company that EndoSonics presently intends to distribute or otherwise transfer to EndoSonics stockholders a portion of the CVD shares it will hold on consummation of this offering. While EndoSonics indicated that it may so distribute or transfer up to a majority of the shares it will hold, it also indicated that the precise amount and timing of any such distribution or transfer will depend upon, among other matters, an analysis of the tax consequences to EndoSonics and its stockholders. Any such distribution or transfer may result in a change of control of CVD. Notwithstanding EndoSonics' stated intent, EndoSonics is not obligated to make any such distribution or transfer nor is it obligated to take any action or refrain from taking any action with respect to the shares of CVD which it will hold upon completion of this offering.

OTHER TRANSACTIONS

On September 10, 1994, the Company entered into a Stock Purchase and Technology License Agreement with SCIMED (the "SCIMED Agreement"). Pursuant to the SCIMED Agreement, SCIMED purchased a 19% equity position in the Company for a purchase price of $2,500,000. SCIMED was also granted an exclusive worldwide license to certain site-specific drug delivery/PTCA technology for use in the cardiovascular field in exchange for license and royalty fees. The SCIMED Agreement also requires CVD to provide certain technical assistance and to perform additional research and development relating to the licensed technology in exchange for fees and reimbursement of expenses, respectively. In the event that CVD's SCIMED-funded research and development efforts result in improvements to the licensed technology, SCIMED will have an exclusive worldwide license to the technology in the cardiovascular field and a non-exclusive license outside the cardiovascular field, both of which are subject to the payment of royalties. The SCIMED Agreement may be terminated in the event of breach on 90 days notice by the non-breaching party (or on 30 days notice in certain limited circumstances) or by SCIMED upon 180 days notice.

In connection with the adoption of the Predecessor Plan, the Company issued a warrant to SCIMED in June 1995 to purchase 40,000 shares of Series A Preferred Stock at an exercise price of $6.58 per share in exchange for a waiver of SCIMED's anti-dilution rights under the SCIMED Agreement. The Company subsequently issued a warrant for an additional 20,000 shares of Series A Preferred at $6.58 per share in connection with an increase in the number of shares reserved for issuance under the Predecessor Plan. Following the consummation of this offering, these warrants shall be exercisable for 80,000 shares of Common Stock and 40,000 shares of Common Stock, respectively, at an exercise price of $3.29 per share.

EndoSonics and SCIMED have entered into lock-up agreements with the Company limiting sales of the Company's Common Stock during the 180-day period following the date of this Prospectus. See "Shares Eligible for Future Sale."

CVD intends to extend a loan in the amount of $150,000, to Jeffrey F. O'Donnell, the Company's Vice President of Sales and Marketing. The note, which will be secured by a second deed of trust on Mr. O'Donnell's home, will have a five-year term with interest compounding semi-annually at 6%. The principal and interest will be due five years from the date of the note.

The Company believes that all of the transactions set forth above were made on terms no less favorable to the Company than could have been obtained from unaffiliated third parties. All future transactions, including loans, between the Company and its officers, directors, principal stockholders and their affiliates will be approved by a majority of the Board of Directors, including a majority of the independent and disinterested outside directors on the Board of Directors, and will continue to be on terms no less favorable to the Company than could be obtained from unaffiliated third parties.

DESCRIPTION OF CAPITAL STOCK

The authorized capital stock of the Company consists of 30,000,000 shares of Common Stock, $.001 par value, and 5,000,000 shares of Preferred Stock, $.001 par value, after giving effect to the amendment of the Company's Certificate of Incorporation to delete references to Series A Preferred Stock and Series B Preferred Stock following conversion of such Preferred Stock into Common Stock upon the closing of this offering.

COMMON STOCK

As of March 31, 1996, there were 4,800,000 shares of Common Stock outstanding that were held of record by 2 stockholders. There will be 8,262,500 shares of Common Stock outstanding (assuming no exercise of the Underwriters' overallotment option and assuming no exercise of options after March 31, 1996) after giving effect to the sale of the shares of Common Stock to the public offered hereby and the conversion of the Convertible Obligation and the Company's Series A Preferred Stock and Series B Preferred Stock into Common Stock.

The holders of Common Stock are entitled to one vote per share on all matters to be voted upon by the stockholders. Subject to preferences that may be applicable to any outstanding Preferred Stock, the holders of Common Stock are entitled to receive ratably such dividends, if any, as may be declared from time to time by the Board of Directors out of funds legally available therefore. See "Dividend Policy." In the event of the liquidation, dissolution or winding up of the Company, the holders of Common Stock are entitled to share ratably in all assets remaining after payment of liabilities, subject to prior distribution rights of Preferred Stock, if any, then outstanding. The Common Stock has no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the Common Stock. All outstanding shares of Common Stock are fully paid and nonassessable, and the shares of Common Stock to be issued upon completion of this offering will be fully paid and nonassessable.

PREFERRED STOCK

The Company's Certificate of Incorporation authorizes 5,000,000 shares of Preferred Stock. The Board of Directors has the authority to issue the Preferred Stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, dividend rates, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any series or the designation of such series, without further vote or action by the stockholders. The issuance of Preferred Stock may have the effect of delaying, deferring or preventing a change in control of the Company without further action by the stockholders and may adversely affect the voting and other rights of the holders of Common Stock. The issuance of Preferred Stock with voting and conversion rights may adversely affect the voting power of the holders of Common Stock, including the loss of voting control to others. At present, the Company has no plans to issue any of the Preferred Stock.

ANTITAKEOVER EFFECTS OF PROVISIONS OF THE CERTIFICATE OF INCORPORATION, BYLAWS AND DELAWARE LAW

Certificate of Incorporation and Bylaws

The Certificate of Incorporation provides that, effective upon the closing of this offering, all stockholder actions must be effected at a duly called meeting and not by a consent in writing. The Bylaws provide that the Company's stockholders may call a special meeting of stockholders only upon a request of stockholders owning at least 50% of the Company's capital stock. These provisions of the Certificate of Incorporation and Bylaws could discourage potential acquisition proposals and could delay or prevent a change in control of the Company. These provisions are intended to enhance the likelihood of continuity and stability in the composition of the Board of Directors and in the policies formulated by the Board of Directors and to discourage certain types of transactions that may involve an actual or threatened change of control of the Company. These provisions are designed to reduce the vulnerability of the Company to an unsolicited acquisition proposal. The provisions also are intended to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for the Company's shares and, as a consequence, they also may inhibit fluctuations in the market price of the Company's shares that could result from actual or rumored takeover attempts. Such provisions also may have

47

the effect of preventing changes in the management of the Company. See "Risk Factors -- Effect of Certain Charter Provisions; Antitakeover Effects of Certificate of Incorporation, Bylaws and Delaware Law."

Delaware Takeover Statute

The Company is subject to Section 203 of the Delaware General Corporation Law ("Section 203"), which, subject to certain exceptions, prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that such stockholder became an interested stockholder, unless: (i) prior to such date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;
(ii) upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned (x) by persons who are directors and also officers and (y) by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or (iii) on or subsequent to such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

Section 203 defines business combination to include: (i) any merger or consolidation involving the corporation and the interested stockholder; (ii) any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder; (iii) subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder; (iv) any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; or (v) the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation. In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by such entity or person.

SHARES ELIGIBLE FOR FUTURE SALE

Upon completion of this offering, the Company will have 8,262,500 shares of Common Stock outstanding (assuming no exercise of options after March 31, 1996 and the conversion of the Convertible Obligation. Of these shares, the 3,400,000 shares sold in this offering will be freely tradeable without restriction or further registration under the Securities Act, except that any shares purchased by "affiliates" of the Company, as that term is defined under the Securities Act ("Affiliates"), may generally only be sold in compliance with the limitations of Rule 144 described below.

SALES OF RESTRICTED SHARES

The remaining 4,862,500 shares of Common Stock are deemed "Restricted Shares" under Rule 144. The number of shares of Common Stock available for sale in the public market is limited by restrictions under the Securities Act and lock-up agreements under which the holders of such shares have agreed not to sell or otherwise dispose of any of their shares for a period of 180 days after the date of this Prospectus without the prior written consent of the Representatives of the Underwriters. On the date of this Prospectus, no shares other than the 3,400,000 shares offered hereby will be eligible for sale. Beginning 180 days after the date of this Prospectus (or earlier with the consent of the Representatives of the Underwriters), 4,000,000 Restricted Shares will become available for sale in the public market subject to certain limitations of Rule 144 of the Securities Act. In addition, the Company intends to register on a registration statement on Form S-8, approximately 30 days after the effective date of this offering, a total of 200,000 shares of Common Stock reserved for issuance under the Company's Employee Stock Purchase Plan and a total of 1,200,000 shares of Common Stock subject to outstanding options or reserved for issuance under the Company's 1996 Stock Option/Stock Issuance Plan. See "Certain Transactions -- Relationship with EndoSonics Corporation" and "Risk Factors -- Control by Existing Stockholder; Limitations on Pooling-of-Interests Accounting" for a discussion of possible distributions of CVD shares held by EndoSonics to EndoSonics' stockholders.

In general, under Rule 144 of the Securities Act as currently in effect, beginning 90 days after this offering, a person (or persons whose shares are aggregated) who has beneficially owned "restricted" shares for at least two years, including a person who may be deemed an Affiliate of the Company, is entitled to sell within any three-month period a number of shares of Common Stock that does not exceed the greater of 1% of the then-outstanding shares of Common Stock of the Company (approximately 82,625 shares after giving effect to this offering) and the average weekly trading volume of the Common Stock on the Nasdaq National Market during the four calendar weeks preceding such sale. Sales under Rule 144 of the Securities Act are subject to certain restrictions relating to manner of sale, notice and the availability of current public information about the Company. A person who is not an Affiliate of the Company at any time during the ninety days preceding a sale, and who has beneficially owned shares for at least three years, would be entitled to sell such shares immediately following this offering without regard to the volume limitations, manner of sale provisions or notice or other requirements of Rule 144 of the Securities Act. However, the transfer agent may require an opinion of counsel that a proposed sale of shares comes within the terms of Rule 144 of the Securities Act prior to effecting a transfer of such shares.

Prior to this offering, there has been no public market for the Common Stock of the Company and no predictions can be made of the effect, if any, that the sale or availability for sale of shares of additional Common Stock will have on the market price of the Common Stock. Nevertheless, sales of substantial amounts of such shares in the public market, or the perception that such sales could occur, could adversely affect the market price of the Common Stock and could impair the Company's future ability to raise capital through an offering of its equity securities.

OPTIONS

As of March 31, 1996, options to purchase a total of 977,000 shares of Common Stock pursuant to the 1995 Stock Option Plan were outstanding and exercisable. All of the shares subject to options are subject to Lock-up Agreements. See "-- Lock-up Agreements." An additional 223,000 shares of Common Stock were available as of May 1, 1996 for future option grants or direct issuances under the 1996 Stock Option/Stock Issuance Plan. See "Management -- 1996 Stock Option/Stock Issuance Plan," and Notes 9 and 11 of Notes to Financial Statements.

49

Rule 701 under the Securities Act provides that shares of Common Stock acquired on the exercise of outstanding options may be resold by persons other than Affiliates, beginning 90 days after the date of this Prospectus, subject only to the manner of sale provisions of Rule 144, and by Affiliates, beginning 90 days after the date of this Prospectus, subject to all provisions of Rule 144 except its two-year minimum holding period. The Company intends to file one or more registration statements on Form S-8 under the Securities Act to register all shares of Common Stock subject to outstanding stock options and Common Stock issued or issuable pursuant to the Company's 1996 Stock Option/Stock Issuance Plan and Common Stock issuable pursuant to the Company's Employee Stock Purchase Plan. The Company expects to file the registration statements covering shares issuable pursuant to the Employee Stock Purchase Plan and 1996 Stock Option/Stock Issuance Plan approximately 30 days after the closing of this offering. Such registration statements are expected to become effective upon filing. Shares covered by these registration statements will thereupon be eligible for sale in the public markets, subject to the Lock-up Agreements, if applicable.

LOCK-UP AGREEMENTS

Each of the Company's directors and officers and each stockholder of the Company has agreed that they will not, without the prior written consent of the Representatives of the Underwriters, offer, sell, contract to sell or otherwise dispose of any shares of Common Stock beneficially owned by them or any shares issuable upon exercise of stock options for a period of 180 days from the effective date of this offering.

REGISTRATION RIGHTS

Further, SCIMED may require the Company to file additional registration statements on Form S-3 at the Company's expense. These rights are subject to certain conditions and limitations, among them the right of the underwriters of an offering to limit the number of shares included in such registration in certain circumstances.

The Underwriting Agreement provides that the obligations of the Underwriters are subject to certain conditions precedent, including the absence of any material adverse change in the Company's business and the receipt of certain certificates, opinions and letters from the Company and its counsel and independent auditors. The nature of the Underwriters' obligations is such that they are committed to purchase all shares of Common Stock offered hereby if any of such shares are purchased.

The Representatives have advised the Company that the Underwriters propose to offer the shares of Common Stock to the public at the offering price set forth on the cover page of this Prospectus and to certain dealers at such price less a concession of not in excess of $ per share, of which $ may be reallocated to other dealers. After the Offering, the public offering price, concession and reallowance to dealers may be reduced by the Representatives. No such reduction shall change the amount of proceeds to be received by the Company as set forth on the cover page of this Prospectus.

The Company has granted the Underwriters an option for thirty days after the date of this Prospectus to purchase, at the offering price, less the underwriting discounts and commissions as set forth on the cover page of this Prospectus, up to 510,000 additional shares of Common Stock at the same price per share as the Company receives for the 3,400,000 shares of Common Stock offered hereby, solely to cover over-allotments, if any. If the Underwriters exercise their over-allotment option, the Underwriters have severally agreed, subject to certain conditions, to purchase approximately the same percentage thereof that the number of shares of Common Stock to be purchased by each of them, as shown in the foregoing table, bears to the 3,400,000 shares of Common Stock offered hereby. The Underwriters may exercise such option only to cover the over-allotments in connection with the sale of the 3,400,000 shares of Common Stock offered hereby.

Each of the Company's directors and officers and each stockholder of the Company, has agreed not to offer, sell, contract to sell or otherwise dispose of Common Stock or securities convertible into or exchangeable for, or any rights to purchase or acquire, Common Stock for a period of 180 days following the Effective Date, without the prior written consent of Volpe, Welty & Company.

51

contract to sell or otherwise dispose of any shares of Common Stock or any securities convertible into or exchangeable for, or any rights to purchase or acquire, Common Stock for a period of 180 days following the date of this Prospectus without the prior written consent of Volpe, Welty & Company, except for the granting of options or the sale of stock pursuant to the Company's existing stock and option plans. Volpe, Welty & Company, in its discretion, may waive the foregoing restrictions in whole or in part, with or without a public announcement of such action.

The offering of the shares is made for delivery when, as and if accepted by the Underwriters and subject to prior sale and to withdrawal, cancellation or modification of the offering without notice. The Underwriters reserve the right to reject an order for the purchase of shares in whole or in part.

Prior to this offering, there has been no public market for the Company's Common Stock. The initial public offering price of the Common Stock will be determined by negotiations between the Company and the Representatives. Among the factors considered in determining the initial public offering price of the Common Stock, in addition to prevailing market conditions will be the Company's historical performance, estimates of the business potential and earnings prospects of the Company, an assessment of the Company's management and the consideration of the above factors in relation to market valuations of companies in related business.

The Company has agreed to indemnify the Underwriters against certain liabilities that may be incurred in connection with this offering, including liabilities under the Securities Act, or to contribute payments that the Underwriters may be required to make in respect thereof.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Shareholders
CardioVascular Dynamics, Inc.

We have audited the accompanying balance sheets of CardioVascular Dynamics, Inc. (a subsidiary of EndoSonics Corporation) as of December 31, 1994 and 1995, and the related statements of operations, stockholders' equity (net capital deficiency) and cash flows for the period from June 10, 1993 to December 31, 1993 and the years ended December 31, 1994 and 1995, and the statements of operations, stockholders' equity and cash flows of the predecessor company for the period from January 1, 1993 through June 9, 1993. 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 audit.

We conducted our audit in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of CardioVascular Dynamics, Inc. at December 31, 1994 and 1995, and the results of its operations and its cash flows for the period from June 10, 1993 to December 31, 1993 and the years ended December 31, 1994 and 1995 and the results of operations and cash flows of the predecessor company for the period from January 1, 1993 through June 9, 1993, in conformity with generally accepted accounting principles.

(IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)

1. BUSINESS, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Business and Basis of Presentation

CardioVascular Dynamics, Inc. (the "Predecessor") was incorporated on March 16, 1992 in the State of California. The Predecessor, and its successor corporation discussed below, develops, manufactures and markets proprietary therapeutic catheters used to treat certain vascular diseases.

In June 1992, EndoSonics Corporation ("EndoSonics" or "Parent") acquired a 40% preferred interest in the Predecessor. EndoSonics, a Delaware corporation, develops, manufactures, and markets intravascular ultrasound imaging systems and diagnostic, therapeutic and imaging catheters for the treatment of coronary and peripheral vascular disease.

In June 1993, EndoSonics acquired all of the remaining Preferred and Common Stock of the Predecessor. The acquisition was accomplished through a merger between the Predecessor and EndoSonics Acquisition Corp., a wholly owned subsidiary of EndoSonics (which then changed its name to CardioVascular Dynamics, Inc.). The merger was treated as a tax-free reorganization for income tax purposes. The accompanying financial statements present the results of operations, cash flows and changes in stockholders' equity for the Predecessor through June 9, 1993, and of CardioVascular Dynamics, Inc. (hereinafter referred to as "CVD" or the "Company") thereafter. For practical purposes the actual cut-off date was June 30, 1993; however, the activity between June 10, 1993 and June 30, 1993 was not material.

The acquisition by EndoSonics resulted in a new basis for the CVD assets and liabilities. Accordingly, the purchase price paid by EndoSonics has been allocated to the identifiable assets and liabilities, including in-process research and development, which was immediately expensed as no CVD products had received regulatory approval and the technology did not have identifiable alternative uses. The amount by which the purchase price exceeded the Predecessor's net book value has been reflected as paid-in capital in the accompanying financial statements. Pursuant to the terms of the original merger agreement, in June 1995 EndoSonics issued an additional 50,000 shares of its Common Stock to the former shareholders of the Predecessor. The fair market value of such shares of $488 has been reflected in the accompanying financial statements as an additional charge for acquired in-process technology.

Subsequent to the acquisition, EndoSonics began performing certain services for CVD (see Note 3), including general management, accounting, cash management, and other administrative and engineering services. The amounts charged to CVD for such services have been determined based on proportional cost allocations and have been agreed to by the management of CVD and EndoSonics. In the opinion of CVD's management, the allocation methods used are reasonable. Such allocations, however, are not necessarily indicative of costs that would have been incurred had CVD continued to operate independent of EndoSonics. No formal agreement currently exists which specifies the nature of services to be provided by EndoSonics to CVD, or the charges for such services. Therefore, the 1995 amounts are not necessarily indicative of the future charges to be incurred by CVD.

In 1994, the Board of Directors of CVD approved a 16,200-for-1 Common Stock split which has been reflected retroactively for all periods subsequent to the merger in the accompanying financial statements (See Note 11).

Interim Results

The accompanying balance sheet as of March 31, 1996 and the statements of operations, stockholders' equity and cash flows for the three months ended March 31, 1995 and 1996 are unaudited. In the opinion of

management, the statements have been prepared on the same basis as the audited financial statements and include all adjustments, consisting only of normal recurring adjustments, necessary for the fair statement of the results of interim periods. The data disclosed in these notes to the financial statements for these periods are unaudited.

Use of Estimates

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

Inventories

Inventories are comprised of raw materials, work-in-process and finished goods and are stated at the lower of cost, determined on an average cost basis, or market value.

Property and Equipment

Property and equipment are stated at cost and depreciated or amortized on a straight-line basis over the lesser of the estimated useful lives of the assets or the lease term. The estimated useful lives range from three to five years.

Concentrations of Credit Risk and Significant Customers

The Company maintains its cash in deposit accounts at a major financial institution.

The Company sells its products primarily to medical institutions and distributors worldwide. The Company performs ongoing credit evaluations of its customers' financial condition and generally does not require collateral from customers. Management believes that an adequate allowance for doubtful accounts has been provided.

During 1994 and 1995, product sales to Fukuda Denshi Co., Ltd., ("Fukuda"), the Company's Japanese distributor (see Note 4), comprised 61% and 18% of total revenue. Accounts receivable from Fukuda represented 78% and 15% of net accounts receivable at December 31, 1994 and 1995, respectively.

During the period from June 10, 1993 to December 31, 1993, product sales to another of the Company's international distributors comprised 57% of total revenue. One customer comprised 12% of revenues for the year ended December 31, 1995 and 14% of accounts receivable at December 31, 1995.

Export Sales

The Company had export sales by region as follows:

Revenue Recognition and Warranty

The Company recognizes revenue from the sale of its products when the goods are shipped to its customers. Reserves are provided for anticipated product returns and warranty expenses at the time of shipment.

Accounting for Stock-Based Compensation

In October 1995, the Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation," ("SFAS 123") was issued and is effective for the Company's 1996 year end. The Company intends to continue to account for employee stock options in accordance with APB Opinion No. 25 and will make the pro forma disclosures required by SFAS 123 beginning in 1996.

Income Taxes

Since June 1993, the Company's results of operations have been included in consolidated tax returns filed by EndoSonics. There was no income tax provision for the consolidated tax group during the periods covered by these financial statements. All net operating loss and credit carryforwards and deferred tax assets and liabilities have been disclosed herein on a separate company basis for CVD.

Pro Forma Net Loss Per Share

Pro forma net loss per share is computed using the weighted average number of shares of Common Stock, convertible Preferred Stock (using the as-if-converted method) and Common Stock issuable upon conversion of the Convertible Obligation, outstanding. Common equivalent shares from stock options and warrants are not included as the effect is anti-dilutive, except that in accordance with Securities and Exchange Commission Staff Accounting Bulletins, common equivalents shares issued by the Company at prices substantially below the anticipated initial public offering price during the period beginning one year prior to the proposed public offering have been included in the calculation as if they were outstanding for all periods presented (using the treasury stock method and the estimated initial public offering price).

Net loss per share information calculated in accordance with APB Opinion No. 15 for the periods from January 1, 1993 to June 9, 1993 (predecessor entity) and from June 10, 1993 to December 31, 1993 has not been presented as such information is not meaningful as a result of the changes in the Company's capital structure during those periods.

2. SCIMED LIFE SYSTEMS, INC.

In September 1994, CVD and EndoSonics entered into a Stock Purchase and Technology License Agreement with SCIMED Life Systems, Inc. ("SCIMED"). SCIMED acquired a 19% interest in CVD in exchange for $2,500 in cash. If the Company has not completed an initial public offering, or in certain other circumstances, at the three year anniversary of the agreement, SCIMED may exchange its shares of CVD Series A Preferred Stock for shares of EndoSonics Common Stock at a guaranteed conversion rate such that the value of the EndoSonics shares issued will not be less than $2,500. The Company also granted SCIMED the right, through the earlier of December 31, 1997 or the effective date of an initial registration, and offering of CVD shares to the public, to maintain its 19% ownership interest ("anti-dilution right").

CVD also granted SCIMED an exclusive license to certain patents in the cardiovascular field of use, which allows SCIMED to manufacture the Transport PTCA infusion catheter (the "Transport") developed by CVD in exchange for a $1,000 license fee that was paid in 1994.

sales of the Transport and other products which use this patented technology. CVD retains rights to this technology and the associated patents for use outside of the cardiovascular field.

During June 1995, the Company issued a warrant to SCIMED to purchase up to 40,000 shares of Series A Preferred Stock at an exercise price of $6.58 per share in exchange for a waiver of SCIMED's anti-dilution right. The warrant expires in September 1997.

SCIMED also paid CVD $220 and $641 in 1994 and 1995, respectively, on a cost reimbursement basis to fund continuing development of the technology and for other support. Additionally, the Company recorded $43 in product sales to SCIMED during 1994 (none in 1995) and had accounts receivable from SCIMED totaling $125 as of December 31, 1994, none at December 31, 1995 and $100 at March 31, 1996.

The agreement provides Fukuda with exclusive distribution rights relative to certain of the Company's products in Japan for periods extending through May 1999, which may be extended at the option of the parties. Distribution fee revenue received from Fukuda are deferred and are being recognized as revenue over the initial periods covered by the respective agreements.

In July 1995 and May 1996, the distribution agreement with Fukuda was amended. In exchange for the exclusive distribution rights to additional CVD products, the Company received $750 which is convertible into Common Stock upon the consummation of this offering. The Company has accounted for this as a convertible obligation payable as of December 31, 1995.

ACS was granted an option, which was exercised in February 1996, to obtain exclusive worldwide rights to certain CVD perfusion technology. In exchange for the perfusion technology, ACS is obligated to make milestone and minimum royalty payments to CVD, and also has certain obligations to develop and market the perfusion technology. An initial milestone of $150 was earned in the three-months ended March 31, 1996.

The Company has entered into a license agreement with EndoSonics pursuant to which CVD granted EndoSonics the non-exclusive, royalty-free right to certain technology for use in the development and sale of certain products.

The holders of Preferred Stock are entitled to receive dividends when and if declared by the Board of Directors. These dividends are in preference to any declaration or payment of any dividends or distributions with respect to the Company's Common Stock. As of December 31, 1995, no dividends have been declared.

Preferred stockholders have voting rights equivalent to the number of shares of Common Stock into which their shares are convertible. Subject to certain antidilution provisions and other adjustments, each share of Series A and Series B Preferred Stock is convertible, at the holder's option, into two shares of Common Stock. All shares of Preferred Stock convert automatically to Common Stock upon the earlier of a public offering of the Company's Common Stock with an aggregate offering price of $7,500 or upon the date which the Company obtains the consent of the holders of a majority of the then-outstanding shares of Preferred Stock.

Stock Option Plan

Under the terms of the Company's 1995 Stock Option Plan (the "1995 Plan") eligible key employees, directors, and consultants can receive options to purchase shares of the Company's Common Stock at a price not less than 100% for incentive stock options and 85% for nonqualified stock options of the fair value on the date of grant, as determined by the Board of Directors. The Company has authorized 977,000 shares of Common Stock for issuance under the 1995 Plan. The options granted under the 1995 Plan are exercisable over a maximum term of ten years from the date of grant and generally vest over a four year period. Shares underlying the exercise of unvested options are subject to various restrictions as to resale and right of repurchase by the Company which lapses over the vesting period.

Through December 31, 1995 the Company had granted options to purchase 957,000 shares of Common Stock with exercise prices ranging from $1.00 to $1.50. An additional 20,000 options were granted during the three-month period ended March 31, 1996 at an exercise price of $2.50 per share. No options have been exercised and 125,000 options were exercisable at December 31, 1995 (184,458 at March 31, 1996).

During 1995, the Company recorded deferred compensation of approximately $345 for financial reporting purposes to reflect the difference between the exercise price of certain options and the deemed fair value, for financial statement presentation purposes, of the Company's shares of Common Stock. An additional $50 of deferred compensation was recorded during the three-month period ended March 31, 1996. Deferred compensation is being amortized over the vesting period of the related options.

The Company believes that, based on a number of factors including the lack of an earnings history, there is uncertainty regarding the realizability of the deferred tax assets such that a full valuation allowance has been recorded. The valuation allowance increased by $317, $391 and $1,072 in 1993, 1994 and 1995, respectively.

At December 31, 1995, the Company has net operating loss carryforwards for federal income tax purposes of approximately $3,800, which expire in the years 2006 through 2010 and net operating loss carryforwards for state tax purposes of approximately $1,000 which expire in the years 1997 through 2000.

Because of the "change of ownership" provision of the Tax Reform Act of 1986, utilization of the Company's net operating loss carryforwards may be subject to an annual limitation against taxable income in future periods. As a result of the annual limitation, a portion of these carryforwards may expire before ultimately becoming available to reduce future income tax liabilities.

11. SUBSEQUENT EVENTS

In May 1996, the Board of Directors authorized management of the Company to file a registration statement with the Securities and Exchange Commission authorizing the issuance of 3,400,000 shares of Common Stock to the public (the "offering"). If the offering is consummated under the terms presently anticipated, each share of convertible Preferred Stock outstanding will convert into two shares of Common Stock and the Convertible Obligation will convert into 62,500 shares of Common Stock (assuming an initial public offering price of $12.00 per share). Unaudited pro forma stockholders' equity, as adjusted for the assumed conversion of the convertible Preferred Stock and Convertible Obligation described above, is set forth on the accompanying balance sheet.

In anticipation of the offering, the Company effected a 2-for-1 stock split of all outstanding shares of Common Stock and options and changed the conversion ratio of Preferred Stock to two shares of Common Stock for each Preferred share. All Common share and per share amounts included in the accompanying

(IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)

financial statements have been retroactively adjusted to reflect the stock split as well as the change in the Preferred Stock conversion ratio.

In May 1996 the Company adopted the 1996 Stock Option/Stock Issuance Plan (the "1996 Plan") which is the successor to the Company's existing 1995 Plan (see Note 9). A total of 1,200,000 shares of Common Stock have been reserved for future issuance under the 1996 Plan including those shares previously reserved under the 1995 Plan. The 1996 Plan provides for the grant of stock options or issuances of stock to employees, consultants and directors of the Company.

In May 1996, the Company also adopted the 1996 Employee Stock Purchase Plan (the "Purchase Plan"). A total of 200,000 shares of Common Stock are reserved for issuance under the Purchase Plan. The Purchase Plan permits eligible employees to purchase Common Stock through payroll deductions at a price equal to the lower of 85% of the fair market value of the Company's Common Stock at the beginning or end of the applicable offering period.

During May 1996, the Company agreed to issue an additional warrant to SCIMED to purchase up to 20,000 shares of Series A Preferred Stock at an exercise price of $6.58 per share in exchange for a waiver of SCIMED's anti-dilution right related to the shares to be issued under the 1996 Plan. (See Note 2).

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 145 of the Delaware General Corporation Law authorizes a court to award or a corporation's Board of Directors to grant indemnification to directors and officers in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act of 1933, as amended (the "Securities Act"). Article VIII of the Registrant's Bylaws provides for mandatory indemnification of its directors and officers and permissible indemnification of employees and other agents to the maximum extent permitted by the Delaware General Corporation Law. The Registrant's Certificate of Incorporation provides that, pursuant to Delaware law, its directors shall not be liable for monetary damages for breach of the directors' fiduciary duty as directors to the Company and its stockholders. This provision in the Certificate of Incorporation does not eliminate the directors' fiduciary duty, and in appropriate circumstances equitable remedies such as injunctive or other forms of non-monetary relief will remain available under Delaware law. In addition, each director will continue to be subject to liability for breach of the director's duty of loyalty to the Company for acts or omissions not in good faith or involving intentional misconduct, for knowing violations of law, for actions leading to improper personal benefit to the director, and for payment of dividends or approval of stock repurchases or redemptions that are unlawful under Delaware law. The provision also does not affect a director's responsibilities under any other law, such as the federal securities laws or state or federal environmental laws. The Registrant has entered into Indemnification Agreements with its directors, a form of which is attached as Exhibit 10.1 hereto and incorporated herein by reference. The Indemnification Agreements provide the Registrant's directors with further indemnification to the maximum extent permitted by the Delaware General Corporation Law. Reference is also made to the Underwriting Agreement contained in Exhibit 1.1 hereto, indemnifying officers and directors of the Registrant against certain liabilities.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

Since June 1993, the Registrant has issued and sold the following securities:

1. On September 10, 1994, the Company issued and sold an aggregate of 380,000 shares of Common Stock (subsequently recapitalized into Series A Preferred Stock) to SCIMED for an aggregate purchase price of $2,500,000.

II-1


2. On July 17, 1995, the Company issued a $750,000 convertible obligation to Fukuda. The convertible obligation will convert into Common Stock at the public offering price upon the consummation of this offering.

3. On June 30, 1995 and May 2, 1996, the Company issued warrants to SCIMED to purchase 40,000 shares of Series A Preferred Stock and 20,000 shares of Series A Preferred Stock, respectively, each at an exercise price of $6.58 per share. The warrants were issued in connection with the waiver of certain rights by SCIMED under the Stock Purchase and Technology License Agreement dated September 10, 1994, as amended on September 29, 1995.

4. On March 29, 1996, the Company issued and sold an aggregate of 400,000 shares of Series B Preferred Stock to EndoSonics Corporation for an aggregate purchase price of $8,000,000.

The issuances of the securities described above were deemed to be exempt from registration under the Securities Act in reliance on Section 4(2) of such Act as transactions by an issuer not involving any public offering. In addition, the recipients of securities in each such transaction represented their intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof and appropriate legends were affixed to the share certificates issued in such transactions. All recipients had adequate access, through their relationships with the Registrant, to information about the Registrant.

ITEM 17. UNDERTAKINGS

The Registrant hereby undertakes to provide to the Underwriters at the closing specified in the Underwriting Agreement, certificates in such denominations and registered in such names as required by the Underwriters to permit prompt delivery to each purchaser.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the Delaware General Corporation Law, the Certificate of Incorporation or the Bylaws of the Registrant, Indemnification Agreements entered into between the Registrant and its directors, the Underwriting Agreement, or otherwise, the Registrant 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 Registrant of expenses incurred or paid by a director, officer, or controlling person of the Registrant 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 hereunder, the Registrant 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 of 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.

The Registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act, the information omitted from the form of Prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in a form of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
(4) or 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of Prospectus 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.

Dear Sirs and Madams:

CardioVascular Dynamics, Inc., a Delaware corporation (the "Company"), proposes to issue and sell 3,400,000 shares (the "Firm Shares") of its authorized but unissued Common Stock, $0.001 par value (the "Common Stock"). The Company proposes to grant to the Underwriters (as defined below) an option to purchase up to 510,000 additional shares of Common Stock (the "Optional Shares" and, with the Firm Shares, collectively, the "Shares"). The Common Stock is more fully described in the Registration Statement and the Prospectus hereinafter mentioned. EndoSonics Corporation, a Delaware corporation, is hereinafter referred to as the "Principal Securityholder."

The Company hereby confirms the agreements made with respect to the purchase of the shares by the several underwriters, for whom you are acting, named in Schedule I hereto (collectively, the "Underwriters," which term shall also include any underwriter purchasing Stock pursuant to Section 3(b) hereof). You represent and warrant that you have been authorized by each of the other Underwriters to enter into this Agreement on its behalf and to act for it in the manner herein provided.

SECTION 1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company hereby represents and warrants to the several Underwriters as of the date hereof and as of each Closing Date (as defined below) that:

(a) The Company has filed with the Securities and Exchange Commission (the "Commission") a registration statement on Form S-1 (No. 333-4560), including the related preliminary


(1) Plus an option to purchase from the Company up to 510,000 additional shares to cover over-allotments.

prospectus, for the registration under the Securities Act of 1933, as amended (the "Securities Act") of the Shares. Copies of such registration statement and of each amendment thereto, if any, including the related preliminary prospectus (meeting the requirements of Rule 430A of the rules and regulations of the Commission) heretofore filed by the Company with the Commission have been delivered to you.

The term Registration Statement as used in this agreement shall mean such registration statement, including all exhibits and financial statements, all information omitted therefrom in reliance upon Rule 430A and contained in the Prospectus referred to below, in the form in which it became effective, and any registration statement filed pursuant to Rule 462(b) of the rules and regulations of the Commission with respect to the shares (a "Rule 462(b) registration statement"), and, in the event of any amendment thereto after the effective date of such registration statement (the "Effective Date"), shall also mean (from and after the effectiveness of such amendment) such registration statement as so amended (including any Rule 462(b) registration statement). The term Prospectus as used in this Agreement shall mean the prospectus relating to the Shares first filed with the Commission pursuant to Rule 424(b) and Rule 430A
(or if no such filing is required, as included in the Registration Statement)
and, in the event of any supplement or amendment to such prospectus after the Effective Date, shall also mean (from and after the filing with the Commission of such supplement or the effectiveness of such amendment) such prospectus as so supplemented or amended. The term Preliminary Prospectus as used in this Agreement shall mean each preliminary prospectus included in such registration statement prior to the time it becomes effective.

The Registration Statement has been declared effective under the Securities Act, and no post-effective amendment to the Registration Statement has been filed as of the date of this Agreement. The Company has caused to be delivered to you copies of each Preliminary Prospectus and has consented to the use of such copies for the purposes permitted by the Securities Act.

(b) The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation, has full corporate power and authority to own or lease its properties and conduct its business as described in the Registration Statement and the Prospectus and as being conducted, and is duly qualified as a foreign corporation and in good standing in all jurisdictions in which the character of the property owned or leased or the nature of the business transacted by it makes qualification necessary (except where the failure to be so qualified would not have a material adverse effect on the business, business prospects, properties, condition (financial or otherwise) or results of operations of the Company).

(c) The Company does not own or control, directly or indirectly, any corporation, association or other entity. The Company is in possession of and operating in compliance with all material authorizations, licenses, permits, consents, certificates and orders material to the conduct of its businesses as described in the Prospectus, all of which are valid and in full force and effect.

(d) Since the respective dates as of which information is given in the Registration Statement and the Prospectus, there has not been any materially adverse change in the business, business prospects, properties, condition (financial or otherwise) or results of operations of the Company, whether or not arising from transactions in the ordinary course of business, other than as set forth in the Registration Statement and the Prospectus, and since such dates, except in the ordinary course of business,


the Company has not entered into any material transaction not referred to in the Registration Statement and the Prospectus.

(e) The Registration Statement and the Prospectus comply, and on the Closing Date (as hereinafter defined) and any later date on which Optional Shares are to be purchased, the Prospectus will comply, in all material respects, with the provisions of the Securities Act and the rules and regulations of the Commission thereunder; on the Effective Date, the Registration Statement did not contain any untrue statement of a material fact and did not omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; and, on the Effective Date the Prospectus did not and, on the Closing Date and any later date on which Optional Shares are to be purchased, will not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that none of the representations and warranties in this subparagraph (iii) shall apply to statements in, or omissions from, the Registration Statement or the Prospectus made in reliance upon and in conformity with information herein or otherwise furnished in writing to the Company by or on behalf of the Underwriters for use in the Registration Statement or the Prospectus.

(f) The Company has authorized and outstanding capital stock as set forth under the heading "Capitalization" in the Prospectus. The issued and outstanding shares of Common Stock have been duly authorized and validly issued, are fully paid and nonassessable, have been issued in compliance with all federal and state securities laws, and were not issued in violation of or subject to any preemptive rights or other rights to subscribe for or purchase securities. Except as disclosed in or contemplated by the Prospectus and the financial statements of the Company and the related notes thereto included in the Prospectus, the Company has no outstanding options to purchase, or any preemptive rights or other rights to subscribe for or to purchase, any securities or obligations convertible into, or any contracts or commitments to issue or sell, shares of its capital stock or any such options, rights, convertible securities or obligations. The description of the Company's stock option, stock bonus and other stock plans or arrangements, and the options or other rights granted and exercised thereunder, set forth in the Prospectus accurately and fairly presents the information required by the Securities Act and the Rules and Regulations to be shown with respect to such plans, arrangements, options and rights.

(g) The Shares are duly authorized, are (or, in the case of Shares to be sold by the Company, will be, when issued and sold to the Underwriters as provided herein) validly issued, fully paid and nonassessable and conform to the description thereof in the Prospectus. No further approval or authority of the stockholders or the Board of Directors of the Company will be required for issuance and sale of the Shares to be sold by the Company as contemplated herein.

(h) The Shares to be issued and sold by the Company will be authorized for listing on the Nasdaq National Market upon official notice of issuance.

(i) The Shares to be sold by the Company will be sold free and clear of any pledge, lien, security interest, encumbrance, claim or equitable interest, and will conform to the description thereof contained in the Prospectus. No preemptive right, co-sale right, registration right, right of first refusal or other similar right to subscribe for or purchase securities of the Company exists with respect to the issuance and sale of the Shares by the Company pursuant to this Agreement. No stockholder of the Company has


any right which has not been waived, or complied with, to require the Company to register the sale of any shares owned by such stockholder under the Securities Act in the public offering contemplated by this Agreement.

(j) The Company has full corporate power and authority to enter into this Agreement and perform the transactions contemplated hereby. This Agreement has been duly authorized, executed and delivered by the Company and constitutes a valid and binding obligation of the Company enforceable in accordance with its terms, except as enforceability may be limited by general equitable principles, bankruptcy, insolvency, reorganization, moratorium laws affecting creditors' rights generally and except as to those provisions relating to indemnity or contribution for liabilities arising under federal and state securities laws. The making and performance of this Agreement by the Company and the consummation of the transactions contemplated hereby (i) will not violate any provisions of the Certificate of Incorporation, Bylaws or other organizational documents of the Company, and (ii) will not conflict with, result in a material breach or violation of, or constitute, either by itself or upon notice or the passage of time or both, a material default under (A) any agreement, mortgage, deed of trust, lease, franchise, license, indenture, permit or other instrument to which the Company is a party or by which the Company or any of its properties may be bound or affected, or (B) any statute or any authorization, judgment, decree, order, rule or regulation of any court or any regulatory body, administrative agency or other governmental body applicable to the Company or any its properties. No consent, approval, authorization or other order of any court, regulatory body, administrative agency or other governmental body that has not already been obtained is required for the execution and delivery of this Agreement or the consummation of the transactions contemplated by this Agreement, except for compliance with the Securities Act, the blue sky laws applicable to the public offering of the Common Shares by the several Underwriters and the clearance of such offering with the NASD.

(k) The financial statements and schedules of the Company and the related notes thereto included in the Registration Statement and the Prospectus present fairly the financial position of the Company as of the respective dates of such financial statements and schedules, and the results of operations and cash flows of the Company for the respective periods covered thereby. Such statements, schedules and related notes have been prepared in accordance with generally accepted accounting principles applied on a consistent basis throughout the periods specified, as certified by the independent accountants named in subsection 3(g). No other financial statements or schedules are required to be included in the Registration Statement. The selected financial data set forth in the Prospectus under the captions "Capitalization" and "Selected Consolidated Financial Information" fairly present the information set forth therein on the basis stated in the Registration Statement.

(l) The Company maintains a system of internal accounting controls sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management's general or specific authorizations,
(ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain accountability for assets, (iii) access to assets is permitted only in accordance with management's general or specific authorization, and (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The representations and warranties given by the Company and its officers to its independent public accountants for the purpose of supporting the letters referred to in Sections 10(f) and 10(g) are true and correct.


(m) The Company is not (i) in violation or default of any provision of its Certificate of Incorporation, Bylaws or other organizational documents, or (ii) in a material breach of or default with respect to any provision of any agreement, judgment, decree, order, mortgage, deed of trust, lease, franchise, license, indenture, permit or other instrument to which it is a party or by which it or any of its properties are bound; and there does not exist any state of facts which, with notice or lapse of time or both would constitute such a breach or default on the part of the Company.

(N) There are no contracts or other documents required to be described in the Registration Statement or to be filed as exhibits to the Registration Statement by the Securities Act or by the Rules and Regulations which have not been described or filed as required. The contracts so described in the Prospectus are in full force and effect on the date hereof.

(o) Except as disclosed in the Prospectus, there are no legal or governmental actions, suits or proceedings pending or threatened to which the Company is or is threatened to be made a party or of which property owned or leased by the Company is or is threatened to be made the subject, which actions, suits or proceedings could, individually or in the aggregate, prevent or adversely affect the transactions contemplated by this Agreement or result in a material adverse change in the business, business prospects, properties, condition (financial or otherwise), or results of operations of the Company; and no labor disturbance by the employees of the Company exists or is imminent which could materially adversely affect the business, business prospects, properties, condition (financial or otherwise), or results of operations of the Company. The Company is not a party or subject to the provisions of any material injunction, judgment, decree or order of any court, regulatory body, administrative agency or other governmental body. Except as disclosed in the Prospectus, there are no material legal or governmental actions, suits or proceedings pending or, to the Company's knowledge, threatened against any executive officers or directors of the Company.

(p) The Company has good and marketable title to all the properties and assets reflected as owned in the financial statements hereinabove described (or elsewhere in the Prospectus), subject to no lien, mortgage, pledge, charge or encumbrance of any kind except (i) those, if any, reflected in such financial statements (or elsewhere in the Prospectus), or (ii) those which are not material in amount to the Company, and do not adversely affect the use made and proposed to be made of such property by the Company. The Company holds its leased properties under valid and binding leases. Except as disclosed in the Prospectus, the Company owns or leases all such properties as are necessary to its operations as now conducted or as proposed to be conducted.

(q) Since the respective dates as of which information is given in the Registration Statement and Prospectus, and except as described in or specifically contemplated by the Prospectus: (i) the Company has not (A) incurred any liabilities or obligations, indirect, direct or contingent, or (B) entered into any oral or written agreement or other transaction, which in the case of (A) or (B) is not in the ordinary course of business; (ii) the Company has not sustained any material loss or interference with its business or properties from fire, flood, windstorm, accident or other calamity, whether or not covered by insurance; (iii) the Company has not paid or declared any dividends or other distributions with respect to its respective capital stock and the Company and its subsidiaries are not in default in the payment of principal or interest on any outstanding debt obligations; (iv) there has not been any change in the capital stock of the Company (other than upon the sale of the Shares hereunder or upon the exercise of any options or

(r) The Company is conducting business in compliance with all applicable laws, rules and regulations of the jurisdictions in which it is conducting business, except where the failure to be so in compliance would not have a material adverse effect on the business, business prospects, properties, condition (financial or otherwise) or results of operations of the Company.

(s) The Company has filed all necessary federal, state and foreign income and franchise tax returns, and all such tax returns are complete and correct in all material respects, and the Company has not failed to pay any taxes which were payable pursuant to said returns or any assessments with respect thereto.

The Company has not been refused any insurance coverage sought or applied for, and the Company has no reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not materially adversely affect the business, business prospects, properties, condition (financial or otherwise) or results of operations of the Company.

(v) The Company is not and, to the best of the Company's knowledge, none of the Company's employees or agents has at any time during the last five years (i) made any unlawful contribution to any candidate for foreign office, or failed to disclose fully any contribution in violation of law, or

(y) Neither the Company nor any of its affiliates does business with the government of Cuba or with any person or affiliate located in Cuba.

(z) Except as specifically disclosed in the Prospectus, the Company has sufficient trademarks, trade names, patent rights, copyrights, licenses, approvals and governmental authorizations to conduct their businesses as now conducted; the expiration of any trademarks, trade names, patent rights, copyrights, licenses, approvals or governmental authorizations would not have a material adverse effect on the business, business prospects, properties, condition (financial or otherwise) or results of operations have been of the Company; the Company has no knowledge of any infringement by the Company of trademark, trade name rights, patent rights, copyrights, licenses, trade secret or other similar rights of others; and no claims have been made or are threatened against the Company regarding trademark, trade name, patent, copyright, license, trade secret or other infringement which could have a material adverse effect on the business, business prospects, properties, condition (financial or otherwise) or results of operations or prospects of the Company.

(bb) The Company is not an "investment company" within the meaning of the Investment Company Act of 1940, as amended.

SECTION 2. REPRESENTATION AND WARRANTY OF THE PRINCIPAL SECURITYHOLDER. The Principal Securityholder hereby represents and warrants to the several Underwriters as of the date hereof and as of each Closing Date that:

(a) The Registration Statement and the Prospectus comply, and on the Closing Date (as hereinafter defined) and any later date on which Optional Shares are to be purchased, the Prospectus will comply, in all material respects, with the provisions of the Securities Act and the rules and regulations of the Commission thereunder; on the Effective Date, the Registration Statement did not contain any untrue statement of a material fact and did not omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; and, on the Effective Date the Prospectus did not and, on the Closing Date and any later date on which Optional Shares are to be purchased, will not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that none of the representations and warranties in this subparagraph (iii) shall apply to statements in, or omissions from, the Registration Statement or the Prospectus made in reliance upon and in conformity with information herein or otherwise furnished in writing to the Company by or on behalf of the Underwriters for use in the Registration Statement or the Prospectus.

SECTION 3. PURCHASE OF THE SHARES BY THE UNDERWRITERS.

(a) On the basis of the representations and warranties and subject to the terms and conditions herein set forth, the Company agrees to issue and sell 3,400,000 of the Firm Shares to the several Underwriters, and each of the Underwriters agrees to purchase from the Company the respective aggregate number of Firm Shares set forth opposite its name in Schedule I. The price at which such Firm Shares shall be sold by the Company and purchased by the several Underwriters shall be $___ per share. The obligation of each Underwriter to the Company shall be to purchase from the Company that number of Firm Shares which represents the same proportion of the total number of Firm Shares to be sold by each of the Company pursuant to this Agreement as the number of Firm Shares set forth opposite the name of such Underwriter in Schedule I hereto represents of the total number of shares of the Firm Shares to be purchased by all Underwriters pursuant to this Agreement, as adjusted by you in such manner as you deem advisable to avoid fractional shares. In making this Agreement, each Underwriter is contracting severally and not jointly; except as provided in paragraphs (b) and (c) of this Section 3, the agreement of each Underwriter is to purchase only the respective number of shares of the Firm Shares specified in Schedule I.

(b) If for any reason one or more of the Underwriters shall fail or refuse (otherwise than for a reason sufficient to justify the termination of this Agreement under the provisions of Section 9 or 10 hereof) to purchase and pay for the number of Shares agreed to be purchased by such Underwriter or Underwriters, the Company shall immediately give notice thereof to you, and the non-defaulting Underwriters shall have the right within 24 hours after the receipt by you of such notice to purchase, or procure one or more other Underwriters to purchase, in such proportions as may be agreed upon between you and such purchasing Underwriter or Underwriters and upon the terms herein set forth, all or any part


of Shares which such defaulting Underwriter or Underwriters agreed to purchase. If the non-defaulting Underwriters fail so to make such arrangements with respect to all such shares and portion, the number of Shares which each non-defaulting Underwriter is otherwise obligated to purchase under this Agreement shall be automatically increased on a pro rata basis to absorb the remaining shares and portion which the defaulting Underwriter or Underwriters agreed to purchase; provided, however, that the non-defaulting Underwriters shall not be obligated to purchase the portion which the defaulting Underwriter or Underwriters agreed to purchase if the aggregate number of such Shares exceeds 10% of the total number of Shares which all Underwriters agreed to purchase hereunder. If the total number of Shares which the defaulting Underwriter or Underwriters agreed to purchase shall not be purchased or absorbed in accordance with the two preceding sentences, the Company shall have the right, within 24 hours next succeeding the 24-hour period above referred to, to make arrangements with other underwriters or purchasers satisfactory to you for purchase of such Shares and portion on the terms herein set forth. In any such case, either you or the Company shall have the right to postpone the Closing Date determined as provided in Section 5 hereof for not more than seven business days after the date originally fixed as the Closing Date pursuant to
Section 5 in order that any necessary changes in the Registration Statement, the Prospectus or any other documents or arrangements may be made. If neither the non-defaulting Underwriters nor the Company shall make arrangements within the 24-hour periods stated above for the purchase of all of the Shares which the defaulting Underwriter or Underwriters agreed to purchase hereunder, this Agreement shall be terminated without further act or deed and without any liability on the part of the Company to any non-defaulting Underwriter and without any liability on the part of any non-defaulting Underwriter to the Company. Nothing in this paragraph (b), and no action taken hereunder, shall relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

(c) On the basis of the representations, warranties and covenants herein contained, and subject to the terms and conditions herein set forth, the Company grants an option to the several Underwriters to purchase, severally and not jointly, up to 510,000 Optional Shares from the Company at the same price per share as the Underwriters shall pay for the Firm Shares. Said option may be exercised only to cover over-allotments in the sale of the Firm Shares by the Underwriters and may be exercised in whole or in part at any time on or before the thirtieth day after the date of this Agreement upon written or telegraphic notice by you to the Company setting forth the aggregate number of Optional Shares as to which the several Underwriters are exercising the option. Delivery of certificates for the Optional Shares, and payment therefor, shall be made as provided in Section 5 hereof. The number of Optional Shares to be purchased by each Underwriter shall be the same percentage of the total number of Optional Shares to be purchased by the several Underwriters as such Underwriter is purchasing of the Firm Shares, as adjusted by you in such manner as you deem advisable to avoid fractional shares.

SECTION 4. OFFERING BY UNDERWRITERS.

(a) The terms of the initial public offering by the Underwriters of the Shares to be purchased by them shall be as set forth in the Prospectus. The Underwriters may from time to time change the public offering price after the closing of the initial public offering and increase or decrease the concessions and discounts to dealers as they may determine.


(b) The information (insofar as such information relates to the Underwriters) set forth in the last paragraph on the front cover page and under "Underwriting" in the Registration Statement, any Preliminary Prospectus and the Prospectus relating to the Shares constitutes the only information furnished by the Underwriters to the Company for inclusion in the Registration Statement, any Preliminary Prospectus, and the Prospectus, and you on behalf of the respective Underwriters represent and warrant to the Company that the statements made therein are correct.

SECTION 5. DELIVERY OF AND PAYMENT FOR THE SHARES.

(a) Delivery of certificates for the Firm Shares and the Optional Shares (if the option granted by Section 3(c) hereof shall have been exercised not later than 7:00 A.M., San Francisco time, on the date two business days preceding the Closing Date), and payment therefor, shall be made at the office of Brobeck, Phleger & Harrison LLP, 2200 Geng Road, Palo Alto, California, at 7:00 a.m., San Francisco time, on the [fourth](2) business day after the date of this Agreement, or at such time on such other day, not later than seven full business days after such [fourth] business day, as shall be agreed upon in writing by the Company, and you. The date and hour of such delivery and payment (which may be postponed as provided in Section 4(b) hereof) are herein called the "Closing Date".

(b) If the option granted by Section 3(c) hereof shall be exercised after 7:00 a.m., San Francisco time, on the date two business days preceding the Closing Date, delivery of certificates for the shares of Optional Shares, and payment therefor, shall be made at the office of Brobeck, Phleger & Harrison LLP, 2200 Geng Road, Palo Alto, California, at 7:00 a.m., San Francisco time, on the third business day after the exercise of such option.

(c) Payment for the shares purchased from the Company shall be made to the Company or its order, by (i) one or more certified or official bank check or checks in next day funds (and the Company agrees not to deposit any such check in the bank on which drawn until the day following the date of its delivery to the Company or the Custodian, as the case may be) or (ii) federal funds wire transfer. Such payment shall be made upon delivery of certificates for the shares to you for the respective accounts of the several Underwriters (including without limitation by "full-fast" electronic transfer by Depository Trust Company) against receipt therefor signed by you. Certificates for the shares to be delivered to you shall be registered in such name or names and shall be in such denominations as you may request at least one business day before the Closing Date, in the case of Firm Shares, and at least one business day prior to the purchase thereof, in the case of the Optional Shares. Such certificates will be made available to the Underwriters for inspection, checking and packaging at the offices of agent of Volpe, Welty & Company's clearing agent, Bear Sterns Securities Corp., on the business day prior to the Closing Date or, in the case of the Optional Shares, by 3:00 p.m., New York time, on the business day preceding the date of purchase.

It is understood that you, individually and not on behalf of the Underwriters, may (but shall not be obligated to) make payment to the Company for shares to be purchased by any Underwriter whose


(2) This assumes that the transaction will be priced after the close of market and that T + 4 will apply to the transaction. If the pricing takes place before or during market hours the closing will be three business days after pricing.

check shall not have been received by you on the Closing Date or any later date on which Optional Shares are purchased for the account of such Underwriter. Any such payment by you shall not relieve such Underwriter from any of its obligations hereunder.

SECTION 6. COVENANTS OF THE COMPANY. The Company covenants and agrees as follows:

(a) The Company will (i) prepare and timely file with the Commission under Rule 424(b) a Prospectus containing information previously omitted at the time of effectiveness of the Registration Statement in reliance on Rule 430A and (ii) not file any amendment to the Registration Statement or supplement to the Prospectus of which you shall not previously have been advised and furnished with a copy or to which you shall have reasonably objected in writing or which is not in compliance with the Securities Act or the rules and regulations of the Commission.

(b) The Company will promptly notify each Underwriter in the event of (i) the request by the Commission for amendment of the Registration Statement or for supplement to the Prospectus or for any additional information,
(ii) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, (iii) the institution or notice of intended institution of any action or proceeding for that purpose, (iv) the receipt by the Company of any notification with respect to the suspension of the qualification of the shares for sale in any jurisdiction, or (v) the receipt by it of notice of the initiation or threatening of any proceeding for such purpose. The Company will make every reasonable effort to prevent the issuance of such a stop order and, if such an order shall at any time be issued, to obtain the withdrawal thereof at the earliest possible moment.

(c) The Company will (i) on or before the Closing Date, deliver to you a signed copy of the Registration Statement as originally filed and of each amendment thereto filed prior to the time the Registration Statement becomes effective and, promptly upon the filing thereof, a signed copy of each post-effective amendment, if any, to the Registration Statement (together with, in each case, all exhibits thereto unless previously furnished to you) and will also deliver to you, for distribution to the Underwriters, a sufficient number of additional conformed copies of each of the foregoing (but without exhibits) so that one copy of each may be distributed to each Underwriter, (ii) as promptly as possible deliver to you and send to the several Underwriters, at such office or offices as you may designate, as many copies of the Prospectus as you may reasonably request, and (iii) thereafter from time to time during the period in which a prospectus is required by law to be delivered by an Underwriter or dealer, likewise send to the Underwriters as many additional copies of the Prospectus and as many copies of any supplement to the Prospectus and of any amended prospectus, filed by the Company with the Commission, as you may reasonably request for the purposes contemplated by the Securities Act.

(d) If at any time during the period in which a prospectus is required by law to be delivered by an Underwriter or dealer any event relating to or affecting the Company, or of which the Company shall be advised in writing by you, shall occur as a result of which it is necessary, in the opinion of counsel for the Company or of counsel for the Underwriters, to supplement or amend the Prospectus in order to make the Prospectus not misleading in the light of the circumstances existing at the time it is delivered to a purchaser of the shares, the Company will forthwith prepare and file with the Commission a supplement to the Prospectus or an amended prospectus so that the Prospectus as so supplemented or amended will not contain any untrue statement of a material fact or omit to state any material fact necessary


in order to make the statements therein, in the light of the circumstances existing at the time such Prospectus is delivered to such purchaser, not misleading. If, after the initial public offering of the shares by the Underwriters and during such period, the Underwriters shall propose to vary the terms of offering thereof by reason of changes in general market conditions or otherwise, you will advise the Company in writing of the proposed variation, and, if in the opinion either of counsel for the Company or of counsel for the Underwriters such proposed variation requires that the Prospectus be supplemented or amended, the Company will forthwith prepare and file with the Commission a supplement to the Prospectus or an amended prospectus setting forth such variation. The Company authorizes the Underwriters and all dealers to whom any of the shares may be sold by the several Underwriters to use the Prospectus, as from time to time amended or supplemented, in connection with the sale of the shares in accordance with the applicable provisions of the Securities Act and the applicable rules and regulations thereunder for such period.

(e) Prior to the filing thereof with the Commission, the Company will submit to you, for your information, a copy of any post-effective amendment to the Registration Statement and any supplement to the Prospectus or any amended prospectus proposed to be filed.

(f) The Company will cooperate, when and as requested by you, in the qualification of the shares for offer and sale under the securities or blue sky laws of such jurisdictions as you may designate and, during the period in which a prospectus is required by law to be delivered by an Underwriter or dealer, in keeping such qualifications in good standing under said securities or blue sky laws; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation in any jurisdiction in which it is not so qualified. The Company will, from time to time, prepare and file such statements, reports, and other documents as are or may be required to continue such qualifications in effect for so long a period as you may reasonably request for distribution of the shares.

(g) During a period of five years commencing with the date hereof, the Company will furnish to you, and to each Underwriter who may so request in writing, copies of all periodic and special reports furnished to stockholders of the Company and of all information, documents and reports filed with the Commission (including the Report on Form SR required by Rule 463 of the Commission under the Securities Act).

(h) Not later than the 45th day following the end of the fiscal quarter first occurring after the first anniversary of the Effective Date, the Company will make generally available to its security holders an earnings statement in accordance with Section 11(a) of the Securities Act and Rule 158 thereunder.

(i) The Company agrees to pay all costs and expenses incident to the performance of its obligations under this Agreement, including all costs and expenses incident to (i) the preparation, printing and filing with the Commission and the National Association of Securities Dealers, Inc. ("NASD") of the Registration Statement, any Preliminary Prospectus and the Prospectus, (ii) the furnishing to the Underwriters and the persons designated by them of copies of any Preliminary Prospectus and of the several documents required by paragraph
(c) of this Section 6 to be so furnished, (iii) the printing of this Agreement and related documents delivered to the Underwriters, (iv) the preparation, printing and filing of all supplements and amendments to the Prospectus referred to in paragraph (d) of this Section 6, (v) the


furnishing to you and the Underwriters of the reports and information referred to in paragraph (g) of this Section 6 and (vi) the printing and issuance of stock certificates, including the transfer agent's fees.

(j) The Company agrees to reimburse you, for the account of the several Underwriters, for blue sky fees and related disbursements (including counsel fees and disbursements and cost of printing memoranda for the Underwriters) paid by or for the account of the Underwriters or their counsel in qualifying the shares under state securities or blue sky laws and in the review of the offering by the NASD.

(k) The provisions of paragraphs (i) and (j) of this Section are intended to relieve the Underwriters from the payment of the expenses and costs which the Company hereby agrees to pay and shall not affect any agreement which the Company may make, or may have made, for the sharing of any such expenses and costs.

(l) The Company hereby agrees that, without the prior written consent of Volpe, Welty & Company, the Company will not, for a period of 180 days following the date the Registration Statement becomes effective, (i) offer, sell, contract to sell, make any short sale (including without limitation short against the box), pledge, or otherwise dispose of, directly or indirectly, any shares of Common Stock or any options to acquire shares of Common Stock or securities convertible into or exchangeable or exercisable for or any other rights to purchase or acquire Common Stock (including without limitation, Common Stock of the Company which may be deemed to be beneficially owned in accordance with the rules and regulations of the Commission) other than the exercise or conversion of outstanding options, warrants or convertible securities or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences or ownership of Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise; provided, however, that bona fide gift transactions and transfers which will not result in any change in beneficial ownership may be permitted if the transferee enters into a lock-up agreement in substantially the same form covering the remainder of the lock-up period. The foregoing sentence shall not apply to (A) the shares to be sold to the Underwriters pursuant to this Agreement, (B) shares of Common Stock issued by the Company upon the exercise of options granted under the option plans of the Company (the "Option Plans") or upon the exercise of warrants outstanding as of the date hereof, all as described in footnote (1) to the table under the caption "Capitalization" in the Preliminary Prospectus, and
(C) options to purchase Common Stock granted under the Option Plans.

(m) If at any time during the 25-day period after the Registration Statement becomes effective any rumor, publication or event relating to or affecting the Company shall occur as a result of which in your opinion the market price for the shares has been or is likely to be materially affected (regardless of whether such rumor, publication or event necessitates a supplement to or amendment of the Prospectus), the Company will, after written notice from you advising the Company to the effect set forth above, forthwith prepare, consult with you concerning the substance of, and disseminate a press release or other public statement, reasonably satisfactory to you, responding to or commenting on such rumor, publication or event.

(n) The Company is familiar with the Investment Company Act of 1940, as amended, and has in the past conducted its affairs, and will in the future conduct its affairs, in such a manner to ensure that the Company was not and will not be an "investment company" or a company "controlled" by an


"investment company" within the meaning of the Investment Company Act of 1940, as amended, and the rules and regulations thereunder.

(o) The Company agrees to maintain directors' and officers' insurance in amounts customary for the size and nature of the Company's business for a period of two years from the date of this Agreement.

SECTION 7. INDEMNIFICATION AND CONTRIBUTION.

(a) The Company agrees to indemnify and hold harmless each Underwriter and each person (including each partner or officer thereof) who controls any Underwriter within the meaning of Section 15 of the Securities Act from and against any and all losses, claims, damages or liabilities, joint or several, to which such indemnified parties or any of them may become subject under the Securities Act, the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or the common law or otherwise, and the Company agrees to reimburse each such Underwriter and controlling person for any legal or other expenses (including, except as otherwise hereinafter provided, reasonable fees and disbursements of counsel) incurred by the respective indemnified parties in connection with defending against any such losses, claims, damages or liabilities or in connection with any investigation or inquiry of, or other proceeding which may be brought against, the respective indemnified parties, in each case arising out of or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (including the Prospectus as part thereof and any Rule 462(b) registration statement) or any post-effective amendment thereto (including any Rule 462(b) registration statement), or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus or the Prospectus (as amended or as supplemented if the Company shall have filed with the Commission any amendment thereof or supplement thereto) or the omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that (1) the indemnity agreements of the Company contained in this paragraph (a) shall not apply to any such losses, claims, damages, liabilities or expenses if such statement or omission was made in reliance upon and in conformity with information furnished as herein stated or otherwise furnished in writing to the Company by or on behalf of any Underwriter for use in any Preliminary Prospectus or the Registration Statement or the Prospectus or any such amendment thereof or supplement thereto and (2) the indemnity agreement contained in this paragraph (a) with respect to any Preliminary Prospectus shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, damages, liabilities or expenses purchased the shares which is the subject thereof (or to the benefit of any person controlling such Underwriter) if at or prior to the written confirmation of the sale of such Stock a copy of the Prospectus (or the Prospectus as amended or supplemented) was not sent or delivered to such person and the untrue statement or omission of a material fact contained in such Preliminary Prospectus was corrected in the Prospectus (or the Prospectus as amended or supplemented) unless the failure is the result of noncompliance by the Company with paragraph (c) of Section 6 hereof. The indemnity agreements of the Company contained in this paragraph (a) and the representations and warranties of the Company and Principal Securityholder contained in Section 2 and Section 3 hereof shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any indemnified party and shall survive the delivery of and payment for the shares.


(b) Each Underwriter severally agrees to indemnify and hold harmless the Company, each of its officers who signs the Registration Statement on his own behalf or pursuant to a power of attorney, each of its directors, each other Underwriter and each person (including each partner or officer thereof) who controls the Company or any such other Underwriter within the meaning of Section 15 of the Securities Act, from and against any and all losses, claims, damages or liabilities, joint or several, to which such indemnified parties or any of them may become subject under the Securities Act, the Exchange Act, or the common law or otherwise and to reimburse each of them for any legal or other expenses (including, except as otherwise hereinafter provided, reasonable fees and disbursements of counsel) incurred by the respective indemnified parties in connection with defending against any such losses, claims, damages or liabilities or in connection with any investigation or inquiry of, or other proceeding which may be brought against, the respective indemnified parties, in each case arising out of or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (including the Prospectus as part thereof and any Rule 462(b) registration statement) or any post-effective amendment thereto (including any Rule 462(b) registration statement) or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (as amended or as supplemented if the Company shall have filed with the Commission any amendment thereof or supplement thereto) or the omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, if such statement or omission was made in reliance upon and in conformity with information furnished as herein stated or otherwise furnished in writing to the Company by or on behalf of such indemnifying Underwriter for use in the Registration Statement or the Prospectus or any such amendment thereof or supplement thereto. The indemnity agreement of each Underwriter contained in this paragraph (b) shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any indemnified party and shall survive the delivery of and payment for the shares.

(c) Each party indemnified under the provision of paragraphs
(a) and (b) of this Section 7 agrees that, upon the service of a summons or other initial legal process upon it in any action or suit instituted against it or upon its receipt of written notification of the commencement of any investigation or inquiry of, or proceeding against, it in respect of which indemnity may be sought on account of any indemnity agreement contained in such paragraphs, it will promptly give written notice (the "Notice") of such service or notification to the party or parties from whom indemnification may be sought hereunder. No indemnification provided for in such paragraphs shall be available to any party who shall fail so to give the Notice if the party to whom such Notice was not given was unaware of the action, suit, investigation, inquiry or proceeding to which the Notice would have related and was prejudiced by the failure to give the Notice, but the omission so to notify such indemnifying party or parties of any such service or notification shall not relieve such indemnifying party or parties from any liability which it or they may have to the indemnified party for contribution or otherwise than on account of such indemnity agreement. Any indemnifying party shall be entitled at its own expense to participate in the defense of any action, suit or proceeding against, or investigation or inquiry of, an indemnified party. Any indemnifying party shall be entitled, if it so elects within a reasonable time after receipt of the Notice by giving written notice (the "Notice of Defense") to the indemnified party, to assume (alone or in conjunction with any other indemnifying party or parties) the entire defense of such action, suit, investigation, inquiry or proceeding, in which event such defense shall be conducted, at the expense of the indemnifying party or parties, by counsel chosen by such indemnifying party or parties and reasonably satisfactory to the indemnified party


or parties; provided, however, that (i) if the indemnified party or parties reasonably determine that there may be a conflict between the positions of the indemnifying party or parties and of the indemnified party or parties in conducting the defense of such action, suit, investigation, inquiry or proceeding or that there may be legal defenses available to such indemnified party or parties different from or in addition to those available to the indemnifying party or parties, then counsel for the indemnified party or parties shall be entitled to conduct the defense to the extent reasonably determined by such counsel to be necessary to protect the interests of the indemnified party or parties and (ii) in any event, the indemnified party or parties shall be entitled to have counsel chosen by such indemnified party or parties participate in, but not conduct, the defense. If, within a reasonable time after receipt of the Notice, an indemnifying party gives a Notice of Defense and the counsel chosen by the indemnifying party or parties is reasonably satisfactory to the indemnified party or parties, the indemnifying party or parties will not be liable under paragraphs (a) through (c) of this Section 7 for any legal or other expenses subsequently incurred by the indemnified party or parties in connection with the defense of the action, suit, investigation, inquiry or proceeding, except that (A) the indemnifying party or parties shall bear the legal and other expenses incurred in connection with the conduct of the defense as referred to in clause (i) of the proviso to the preceding sentence and (B) the indemnifying party or parties shall bear such other expenses as it or they have authorized to be incurred by the indemnified party or parties. If, within a reasonable time after receipt of the Notice, no Notice of Defense has been given, the indemnifying party or parties shall be responsible for any legal or other expenses incurred by the indemnified party or parties in connection with the defense of the action, suit, investigation, inquiry or proceeding.

(d) If the indemnification provided for in this Section 7 is unavailable or insufficient to hold harmless an indemnified party under paragraph (a) or (b) of this Section 7, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in paragraph (a) or (b) of this Section 7 (i) in such proportion as is appropriate to reflect the relative benefits received by each indemnifying party from the offering of the shares or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of each indemnifying party in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, or actions in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the shares received by the Company and the total underwriting discount received by the Underwriters, as set forth in the table on the cover page of the Prospectus, bear to the aggregate public offering price of the shares. Relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by each indemnifying party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission.

The parties agree that it would not be just and equitable if contributions pursuant to this paragraph (d) were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to in the


first sentence of this paragraph (d). The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities, or actions in respect thereof, referred to in the first sentence of this paragraph (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigation, preparing to defend or defending against any action or claim which is the subject of this paragraph (d). Notwithstanding the provisions of this paragraph (d), no Underwriter shall be required to contribute any amount in excess of the underwriting discount applicable to the shares purchased by such Underwriter. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations in this paragraph
(d) to contribute are several in proportion to their respective underwriting obligations and not joint.

Each party entitled to contribution agrees that upon the service of a summons or other initial legal process upon it in any action instituted against it in respect of which contribution may be sought, it will promptly give written notice of such service to the party or parties from whom contribution may be sought, but the omission so to notify such party or parties of any such service shall not relieve the party from whom contribution may be sought from any obligation it may have hereunder or otherwise (except as specifically provided in paragraph (c) of this Section 7).

(e) The Company will not, without the prior written consent of each Underwriter, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought hereunder (whether or not such Underwriter or any person who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act is a party to such claim, action, suit or proceeding) unless such settlement, compromise or consent includes an unconditional release of such Underwriter and each such controlling person from all liability arising out of such claim, action, suit or proceeding.

SECTION 8. REIMBURSEMENT OF CERTAIN EXPENSES. In addition to their other obligations under Section 8 of this Agreement, the Company agrees to reimburse on a monthly basis the Underwriters for all reasonable legal and other expenses incurred in connection with investigating or defending any claim, action, investigation, inquiry or other proceeding arising out of or based upon any statement or omission, or any alleged statement or omission, described in paragraph (a) of Section 7 of this Agreement, notwithstanding the absence of a judicial determination as to the propriety and enforceability of the obligations under this Section 8 and the possibility that such payments might later be held to be improper; provided, however, that (i) to the extent any such payment is ultimately held to be improper, the persons receiving such payments shall promptly refund them and (ii) such persons shall provide to the Company, upon request, reasonable assurances of their ability to effect any refund, when and if due.

SECTION 9. TERMINATION. This Agreement may be terminated by you at any time prior to the Closing Date by giving written notice to the Company in accordance with Section 10, or if after the date of this Agreement trading in the Common Stock shall have been suspended, or if there shall have occurred (i) the engagement in hostilities or an escalation of major hostilities by the United States or the declaration of war or a national emergency by the United States on or after the date hereof, (ii) any outbreak of hostilities or other national or international calamity or crisis or change in economic or political conditions if the effect of such outbreak, calamity, crisis or change in economic or political conditions in the financial markets of the United States or the Company's industry sector would, in the Underwriters' reasonable judgment, make the offering or delivery of the shares impracticable, (iii) suspension of trading


in securities generally or a material adverse decline in value of securities generally on the New York Stock Exchange, the American Stock Exchange, or the Nasdaq National Market, or limitations on prices (other than limitations on hours or numbers of days of trading) for securities on either such exchange or system, (iv) the enactment, publication, decree or other promulgation of any federal or state statute, regulation, rule or order of, or commencement of any proceeding or investigation by, any court, legislative body, agency or other governmental authority which in the Underwriters' reasonable opinion materially and adversely affects or will materially or adversely affect the business or operations of the Company, (v) declaration of a banking moratorium by either federal or New York State authorities or (vi) the taking of any action by any federal, state or local government or agency in respect of its monetary or fiscal affairs which in the Underwriters' reasonable opinion has a material adverse effect on the securities markets in the United States. If this Agreement shall be terminated pursuant to this Section 9, there shall be no liability of the Company or the Principal Securityholder to the Underwriters and no liability of the Underwriters to the Company or the Principal Securityholder; provided, however, that in the event of any such termination the Company agrees to indemnify and hold harmless the Underwriters from all costs or expenses incident to the performance of the obligations of the Company under this Agreement, including all costs and expenses referred to in paragraphs (i) and (j) of
Section 6 hereof.

SECTION 10. CONDITIONS OF UNDERWRITERS' OBLIGATIONS.

forth in such a supplement or amendment; (iii) since the respective dates as of which information is given in the Registration Statement in the form in which it originally became effective and the Prospectus contained therein, there has not been any material adverse change or any development involving a prospective material adverse change in or affecting the business, properties, financial condition or results of operations of the Company, whether or not arising from transactions in the ordinary course of business, and, since such dates, except in the ordinary course of business, the Company has not entered into any material transaction not referred to in the Registration Statement in the form in which it originally became effective and the Prospectus contained therein;

(ii) the authorized capital stock of the Company consists of 30,000,000 shares of Common Stock, $0.001 par value, of which there are ______________outstanding shares, and 5,000,000 shares of Preferred Stock, $0.001 par value, of which there are outstanding _____________ shares; all of the outstanding shares of such capital stock (including the Firm Shares and the Optional Shares issued, if any) have been duly authorized and validly issued and are fully paid and nonassessable; any Optional Shares purchased after the Closing Date have been duly authorized and, when issued and delivered to, and paid for by, the Underwriters as provided in the Underwriting Agreement, will be validly issued and fully paid and nonassessable; and no preemptive rights of, or rights of refusal in favor of, stockholders exist with respect to the Shares, or the issue and sale thereof, pursuant to the Certificate of Incorporation or Bylaws of the Company or any other instrument and, to the knowledge of such counsel, there are no contractual preemptive rights that have not been waived, rights of first refusal or rights of co-sale which exist with respect to sale of the Shares by the Company;

(iii) the Registration Statement has become effective under the Securities Act and, to the best of such counsel's knowledge, no stop order suspending the effectiveness of the Registration Statement or suspending or preventing the use of the Prospectus is in effect and no proceedings for that purpose have been instituted or are pending or contemplated by the Commission;

(iv) the Registration Statement and the Prospectus (except as to the financial statements and schedules and other financial data contained therein, as to which such counsel need express no opinion) comply as to form in all material respects with the requirements of the Securities Act and with the rules and regulations of the Commission thereunder;

(v) such counsel have no reason to believe that the Registration Statement (except as to the financial statements and schedules and other financial data contained therein, as to which such counsel need not express any opinion or belief) at the Effective Date contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or that the Prospectus (except as to the financial statements and schedules and other financial data contained therein, as to which such counsel need not express any opinion or belief) as of its date or at the Closing Date (or any later date on which Optional Shares are purchased), contained or contains any


untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading;

(vi) the information required to be set forth in the Registration Statement in answer to Items 9, 10 (insofar as it relates to such counsel) and 11(c) of Form S-1 is to the best of such counsel's knowledge accurately and adequately set forth therein in all material respects or no response is required with respect to such Items, and, the description of the Company's employee stock purchase plan and its stock option plans and the options granted and which may be granted thereunder and the options granted otherwise than under such plans set forth or incorporated by reference in the Prospectus accurately and fairly presents the information required to be shown with respect to said plans and options to the extent required by the Securities Act and the rules and regulations of the Commission thereunder;

(vii) such counsel do not know of any franchises, contracts, leases, documents or legal proceedings, pending or threatened, which in the opinion of such counsel are of a character required to be described in the Registration Statement or the Prospectus or to be filed as exhibits to the Registration Statement, which are not described and filed as required;

(viii) the Underwriting Agreement has been duly authorized, executed and delivered by the Company;

(ix) the Company has full corporate power and authority to enter into the Underwriting Agreement and to sell and deliver the Shares to be sold by it to the several Underwriters; the Underwriting Agreement is a valid and binding agreement of the Company enforceable in accordance with its terms, except as enforceability may be limited by general equitable principles, bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditor's rights generally and except as to those provisions relating to indemnity or contribution for liabilities arising under federal and state securities laws (as to which no opinion need be expressed).

(x) the issue and sale by the Company of the Shares sold by the Company as contemplated by the Underwriting Agreement will not conflict with, or result in a breach of, or constitute a default under the Certificate of Incorporation or Bylaws of the Company or any agreement or instrument known to such counsel to which the Company is a party or by which any of its properties may be bound or any applicable law or regulation, or so far as is known to such counsel, any order, writ, injunction or decree, of any jurisdiction, court or governmental instrumentality;

(xi) all holders of securities of the Company having rights to the registration of shares of Common Stock, or other securities, because of the filing of the Registration Statement by the Company have waived such rights or such rights have expired by reason of lapse of time following notification of the Company's intent to file the Registration Statement;

Copies of any opinions so relied upon shall be delivered to the Representatives and to counsel for the Underwriters and the foregoing opinion shall also state that counsel knows of no reason the Underwriters are not entitled to rely upon the opinions of such local counsel.


ANNEX B

PROPOSED FORM OF OPINION OF GERARD KNOBBE, MARTENS, OLSON & BEAR,
PATENT COUNSEL FOR THE COMPANY

_____________, 1996

Volpe, Welty & Company
Wessels, Arnold & Henderson
Vector Securities International, Inc.
As Representatives of the several Underwriters c/o Volpe, Welty & Company
One Maritime Plaza, 11th Floor
San Francisco, California 94111

Dear Sirs and Madams:

This opinion is being delivered pursuant to Section 10(c) of the Underwriting Agreement between you and CardioVascular Dynamics, Inc. (the "Company") dated __________, 1996 (the "Underwriting Agreement"), relating to a public offering of the Company's common stock pursuant to a registration statement on Form S-1 (Registration No. 333-4560) (the "Registration Statement"). We are intellectual property counsel for the Company, and are familiar with the Company's technology as described in the Prospectus included in the Registration Statement and with the manner in which the Company uses that technology.

We have reviewed the patents listed on Schedule A attached hereto (the "CVD Patents") and the patent applications listed on Exhibit B attached hereto (the "CVD Applications"), relating to the technology described in the Prospectus. Furthermore, we have reviewed copies of assignments where each individual named as an inventor in each of the CVD Patents and Applications described in Exhibits A and B hereto has assigned to CVD his or her entire right, title and interest in the invention described in the subject patent or patent application.

We have relied on such certificates, documents and records with respect to the accuracy of factual matters as we have deemed appropriate for the opinions expressed herein. We have assumed without investigation the authenticity of all documents submitted to us as originals, the conformity to original documents of documents submitted to us as certified or photostatic copies of original documents, the genuineness of all signatures, the legal capacity of natural persons and the accuracy of the statements contained in such certificates.


The validity, binding effect and enforceability of instruments of assignment of patent applications and issued patents may be subject to or affected by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance, or similar laws affecting the enforcement of the rights of creditors generally.

The availability of the remedy of specific performance or injunctive relief, or any other equitable remedy, is subject to the discretion of a court or tribunal before which any proceeding therefor may be brought, and we are not commenting on the question of whether such remedies would be available in the opinions expressed herein.

We are familiar with the technology used by the Company in its business and the manner of its use thereof and have read the Registration Statement and the Prospectus, including particularly the portions of the Registration Statement and the Prospectus referring to patents, trade secrets, trademarks, service marks or other proprietary information or materials.

Based on the foregoing, and subject to the additional qualifications set forth below, it is our opinion that:

1. The Company is listed in the records of the Patent and Trademark Office as the holder of record of each of the CVD Patents and CVD Applications. To the best of our knowledge, we know of no claims of third parties to any ownership interest or lien with respect to any of the CVD Patents or Applications.

2. To the best of our knowledge, the Company is listed in the records of the appropriate foreign office as the sole holder of record of each of the foreign CVD Applications listed on Exhibit B attached hereto. We are not aware of any claim of any third party to any of the foreign applications.

3. We have examined the following portions of the Prospectus included in the Registration Statement (collectively, the "Intellectual Property Portion"):

(i) the section entitled "Risk Factors -- Reliance on Patents and Proprietary Technology; Risk of Patent Infringement"; and

(ii) the sections entitled "Business -- Patents and Proprietary Information," "Business - - Products" and "Business -- Technology".

Insofar as such statements constitute a summary of the CVD Patents and Applications, they are in all material respects accurate summaries and fairly summarize in all material respects the legal matters, documents and proceedings relating to the CVD Patents and Applications described therein. The Company currently owns _____ issued U.S. patents and _____ pending U.S. patent applications.

4. We are not aware of any facts that would lead us to conclude that any of the CVD Patents are invalid or that any patent issued in respect of a CVD Application would be invalid.


5. Except as disclosed in the Intellectual Property Portion, we are not aware that any valid patent owned by any third party is infringed by the activities of the Company described in the Prospectus or by the manufacture, use or sale of any product, device, instrument, drug or other material made and used according to the CVD Patents or Applications.

6. We are not aware of any material defects of form in the preparation or filing of the CVD Applications on behalf of the Company. To the best of our knowledge, the CVD Applications are being diligently pursued by the Company.

7. We are not aware of any pending or threatened action, suit, proceeding or claim by others that the Company is infringing or otherwise violating any patents or trade secrets.

8. We are not aware of any pending or threatened action, suit, proceeding or claim by others challenging the validity or scope of the CVD Patents or Applications.

9. We are not aware of any infringement on the part of any third party of the CVD Patents, trade secrets, know-how or other proprietary rights of the Company.

10. We have no reason to believe that the Registration Statement or the Prospectus (A) contains any untrue statement of a material fact with respect to patents, trade secrets, trademarks, service marks or other proprietary information or materials owned or used by the Company, or the manner of its use thereof, or any allegation on the part of any person that the Company is infringing any patent rights, trade secrets, trademarks, service marks or other proprietary information or materials of any such person or (B) omits to state any material fact relating to patents, trade secrets, trademarks, service marks or other proprietary information or materials owned or used by the Company, or the manner of its use thereof, or any allegation of which such counsel have knowledge, that is required to be stated in the Registration Statement or the Prospectus or is necessary to make the statements therein not misleading.

We express no opinion as to matters governed by laws of any jurisdiction other than the laws of the State of California and federal laws of the United States.

Terms used but not defined herein shall have the meaning set forth in the Underwriting Agreement.

This opinion is solely for your benefit and may not be relied on by, nor may copies be delivered to, any person other than the addressee without our prior written consent.

Wessels, Arnold & Henderson
Vector Securities International, Inc.
As Representatives of the several Underwriters c/o Volpe, Welty & Company
One Maritime Plaza, 11th Floor
San Francisco, California 94111

Dear Sirs and Madams:

This opinion is being delivered pursuant to Section 10(c) of the Underwriting Agreement between you and CardioVascular Dynamics, Inc. (the "Company") dated __________, 1996 (the "Underwriting Agreement"), relating to a public offering of the Company's common stock pursuant to a registration statement on Form S-1 (Registration No. 333-4560) (the "Registration Statement"). This firm has acted as special Federal Food and Drug Administration (FDA) Regulatory Counsel to the Company in connection with the public offering by the Company of up to 3,400,000 shares of its Common Stock.

This opinion is to the best of our knowledge and is based solely on matters of law as they pertain to the Food, Drug and Cosmetic Act, as implemented by FDA, and the Medicare and Medicaid Acts regarding reimbursement as it applies to medical devices, as implemented by the Health Care Financing Administration (HCFA), and we express no opinion as to any other laws, statutes, regulations, or ordinances. Based on, subject to, and limited by the foregoing, we are of the opinion that:

(i) The statements under the captions "Risk Factors--Government Regulation," "Risk Factors-- Limitations on Third Party Reimbursement," "Business--Third Party Reimbursement," "Business--Government Regulation," "Business--Products" and "Business--New Product Development" (collectively, the "Regulatory Portion") in the Registration Statement and the Prospectus which constitutes a part thereof (the "Prospectus") and any amendment or supplement thereto, to the extent that they reflect matters of law, summaries of law or regulations are correct in all material respects, subject to the qualifications set forth therein.

(ii) Subject to the conditions and limitations expressed in this opinion letter and in the Prospectus, nothing has come to the attention of such counsel that would lead such counsel to believe that the Regulatory Portion of the Registration Statement, at the time it became effective, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading or that, on the closing date of the public offering, the information contained in the Regulatory Portion of the Prospectus or any amendment or supplement to the Prospectus contained any untrue statement of a material

C-1

fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

Terms used but not defined herein shall have the meaning set forth in the Underwriting Agreement.

We assume no obligations to advise you of any changes in the foregoing subsequent to the delivery of this opinion. This opinion has been prepared solely for your use in connection with the subject transaction that is the one represented by the Registration Statement and the Prospectus. This opinion may not be used for any other purpose, quoted or otherwise referred to by any person without the written consent of this law firm.

Re: Registration Statement on Form S-1

Ladies and Gentlemen:

We have examined the Registration Statement on Form S-1 originally filed by CardioVascular Dynamics, Inc. (the "Company") with the Securities and Exchange Commission (the "Commission") on May 3, 1996, as thereafter amended or supplemented (the "Registration Statement"), in connection with the registration under the Securities Act of 1933, as amended, of 3,910,000 shares of the Company's Common Stock (the "Shares"). The Shares include an over-allotment option to the Underwriters to purchase up to 510,000 additional shares of the Company's Common Stock and are to be sold to the Underwriters as described in the Registration Statement for resale to the public. As your counsel in connection with this transaction, we have examined the proceedings taken and are familiar with the proceedings proposed to be taken by you in connection with the sale and issuance of the Shares.

It is our opinion that, upon conclusion of the proceedings being taken or contemplated by us, as your counsel, to be taken prior to the issuance of the Shares, the Shares, when issued and sold in the manner described in the Registration Statement, will be validly issued, fully paid and nonassessable.

We consent to the use of this Opinion as an exhibit to said Registration Statement, and further consent to the use of our name wherever appearing in said Registration Statement, including the prospectus constituting a part thereof, and in any amendment thereto.

Very truly yours,

TAX ALLOCATION AGREEMENT

This Tax Allocation Agreement (The "Agreement") is made as of this ____ day of ______, 1996, by and between EndoSonics Corporation, a Delaware corporation ("EndoSonics") and CardioVascular Dynamics, Inc., a Delaware Corporation ("CVD").

WHEREAS, EndoSonics is the common parent of an affiliated group of corporations, as defined in section 1504(a) of the Internal Revenue code of 1986, as amended (the "Code"), of which the CVD is a member; and

WHEREAS, EndoSonics, on behalf of its affiliated group, has filed and will file consolidated federal income tax returns and certain consolidated and/or combined tax returns for state income tax purposes;

WHEREAS, it is anticipated that CVD will no longer be a member of EndoSonics's federal consolidated group following an anticipated initial public offering ("IPO") but may be a member of a consolidated, combining or unitary group under state tax laws following the IPO;

WHEREAS, the parties wish to provide for the allocation among them of tax liability and certain related matters;

NOW, THEREFORE, in consideration of the foregoing premises and of the mutual covenants and agreements contained herein, the parties hereto agree as follows:

1. DEFINITIONS

For purposes of this Agreement, the terms set forth below shall be defined as follows:

(a) "CVD" shall mean (i) CVD, (ii) any corporation which succeeds to and takes into account the net operating loss carryover and other tax attributes of CVD in accordance with Internal Revenue Code Section 381(a), or (iii) any affiliated group of corporations of which CVD is a member and with whom CVD files consolidated federal income tax returns.

(b) "EndoSonics" shall mean and include (i) EndoSonics, (ii) any successor common parent corporation described in Treas. Reg. Section 1.1502-75(d)(2)(i) or (2)(ii), or (iii) any corporation as to which EndoSonics (or a successor corporation described in


clause (ii) hereof) is the "predecessor" within the meaning of Treas. Reg. Section1.1502-1(f)(1), if such corporation acquires EndoSonics (or a successor corporation described in clause (ii) hereof) in a "reverse acquisition" within the meaning of Treas. Reg. Section1.1502-75(d)(3).

(c) "EndoSonics Group" shall mean any group of corporations which files a consolidated federal income tax return with EndoSonics.

(d) "IPO Date" shall mean the closing date of IPO.

(e) "Tax Payment" shall mean any payment required to be made by CVD or EndoSonics to the other in accordance with the terms of this Agreement.

(f) "Tax Liability" shall mean any state or federal income tax liability and shall include any interest or penalties assessed with respect to any deficiency with respect thereto.

2. ALLOCATION OF FEDERAL TAX LIABILITY

EndoSonics and CVD agree and acknowledge that each has incurred substantial net operating losses for federal income tax purposes (on both a separate and consolidated basis) for all taxable years ending prior to the IPO Date and that, as a result, neither has incurred any federal income tax liability for any such year. EndoSonics and CVD further agree and acknowledge that CVD has and will incur a net operating loss for its taxable year ending on the IPO date. Based on such agreement and acknowledgments, CVD shall not be required to make any Tax Payment to EndoSonics for any period ending prior to or on the IPO Date or with respect to any EndoSonics Group consolidated federal income tax returns or for the current taxable year, and EndoSonics will not be required to make any Tax Payments to CVD with respect to such returns for such periods.

3. ALLOCATION OF STATE TAX LIABILITY

A. EndoSonics and CVD agree and acknowledge that each has incurred substantial net operating losses for state income tax purposes (on both a separate and combined basis) for all taxable years ending prior to the IPO Date and that, as a result, neither has incurred any state income tax liability for any such year. EndoSonics and CVD further agree and acknowledge that CVD has and will incur a net operating loss for its taxable year ending on the IPO date. Based on such agreement and acknowledgments, CVD shall not be required to make any Tax Payment to EndoSonics for any period ending prior to or on the IPO Date or with respect to any state income taxes for the portion of the current taxable ending on the IPO date, and EndoSonics will not be required to make any Tax Payments to CVD with respect to state income tax for such periods.


B. Notwithstanding that EndoSonics and CVD may be required to file any consolidated or combined state income tax returns for any period ending after the IPO Date, it is the intention of EndoSonics and CVD by this Agreement to cause CVD's Tax Liability from and after the IPO Date to be the same as it would have been had CVD filed separate returns for such periods. As a result, it is intended that EndoSonics will realize any and all benefits and suffer any and all detriments occasioned by such consolidated or combined reporting.

C. In keeping with the intention of EndoSonics as set forth above, a Tax Payment shall be required to be made with respect to state income taxes incurred in any state with respect to Periods occurring subsequent to the IPO Date in which EndoSonics and CVD are required to file consolidated or combined returns (i) by EndoSonics to CVD to the extent that CVD has a Net Increase in Tax Liability to such state as a result of the filing of a consolidated or combined return; or (ii) by CVD to EndoSonics to the extent that CVD has a Net Decrease in Tax Liability to such state as a result of the filing a consolidated return or report.

D. For purposes of this Paragraph 3, for each taxable year of CVD ending after the IPO Date (treating the period commencing with the IPO Date through the balance of the taxable year as a separate taxable year) and for each jurisdiction in which EndoSonics and CVD are required to file a consolidated or combined state income tax return, CVD shall prepare a hypothetical return on a separate basis (the "Hypothetical Returns"). Such Hypothetical Returns shall be prepared in a manner which is consistent with the methods of accounting and with reporting of income, gain, loss or deduction by CVD for federal income tax purposes. Such Hypothetical Return shall be prepared by CVD and delivered to EndoSonics within 30 days of the date on which CVD has prepared and filed its federal income tax return for such period. CVD shall bear the cost of preparing the Hypothetical Returns except that, in any year in which CVD is required to make a Tax Payment to EndoSonics, CVD may reduce the amount of such payment by the costs directly incurred in preparing such Hypothetical Returns.

E. In the event that any adjustment is made to the federal income tax return of CVD, CVD shall make a corresponding adjustment in its Hypothetical Returns. Similarly, any adjustment to any consolidated or combined state income tax return (other than an adjustment agreed to by EndoSonics without the consent of CVD in accordance with Paragraph 8 hereof) shall require an appropriate adjustment to the Hypothetical Returns. The Net Increase in Tax Liability for any state shall mean the excess of (i) CVD's tax liability to such state in accordance with the consolidated or combined return of EndoSonics and CVD, over
(ii) the tax shown on CVD's hypothetical return for such state. The Net Decrease in Tax Liability for any state shall mean the excess of (i) the tax shown on CVD's hypothetical return for such state, over (ii) CVD's tax liability to such state under the consolidated or combined return of EndoSonics and CVD.


4. PREPARATION AND FILING OF RETURNS

A. Subject to the provisions of Section 8(b) hereof, EndoSonics shall include CVD with EndoSonics in a consolidated or combined return for any period (including periods or portions of any period) following the IPO Date for which EndoSonics determines that it is required to do so or for any period in which EndoSonics, in its sole discretion, determines to do so and for which it believes, in good faith, that it is eligible to do so. CVD shall execute and file such consents, elections, powers of attorney and other documentation as may be required or appropriate for the proper filing of such returns.

B. (I) With respect to any consolidated or combined return which includes EndoSonics or CVD, EndoSonics shall have the right, in its sole discretion, to (i) make any elections which are employed in the preparation and filing of such returns, including any schedules and elections and choice of methods of accounting and depreciation; (ii) determine the substance and manner in which such returns (including schedules) shall be prepared and filed, including without limitation, the substance and manner in which any item of income, gain, loss, deduction or credit shall be reported; (ii) contest, compromise, settle or otherwise control (at its own expense) any adjustment, assessment or deficiency proposed, asserted or assessed as a result of any audit, examination or other proceeding with respect to such returns; (iii) file, prosecute, compromise or settle any claim for refund; and (iv) determine whether any refunds which are available shall be paid by way of refund or credit against the income tax liability.

(II) CVD hereby irrevocably agrees that EndoSonics is authorized to act on CVD's behalf and as the exclusive agent and attorney-in-fact for CVD for all tax matters arising in any state relating to a taxable period for which EndoSonics and CVD prepared consolidated or combined state income tax returns.

(III) Notwithstanding the above, EndoSonics shall not take any position on a consolidated or combined state income tax return with respect to any item of CVD income, gain, loss or deductions which is inconsistent with the reporting of such item by CVD on its federal income tax return.

5. ALTERED FILING STATUS

A. In the event that a state taxing authority seeks to consolidate or combine, under unitary tax principles or otherwise, the items of income and deductions of CVD with those of EndoSonics (a "Unitary Claim") in a taxable period (or portion thereof) following the IPO Date where EndoSonics did not include CVD in such return, then EndoSonics shall be entitled (and CVD hereby irrevocably authorizes EndoSonics) to control the defense, settlement or compromise of any audit, examination, adjustment or other proceeding with such taxing authority and CVD shall execute all powers of


attorney and take all other action to permit EndoSonics to do so. CVD shall also cooperate in any such proceeding. EndoSonics shall bear the full cost of any such such defense, settlement or compromise. In the event that it is ultimately determined that a consolidated or combined state income tax return is required, Paragraph 3.B.(ii) shall apply as if such return had been originally filed.

B. In the event that a state taxing authority seeks to require separate filings with respect to CVD in a year in which EndoSonics included CVD in a consolidated or combined state income tax return (a "Separate Claim"), then EndoSonics shall still be entitled (at its own expense) to (and CVD hereby irrevocably authorizes EndoSonics) to control the defense, settlement or compromise of any audit, examination, adjustment or other proceeding with such taxing authority and CVD shall execute all powers of attorney and take all other action to permit EndoSonics to do so. CVD shall also cooperate in any such proceeding.

6. TIME FOR PAYMENT; DEFAULT INTEREST

A. Any Tax Payment required hereunder with respect to originally filed consolidated or combined state income tax returns shall be paid on or before the later to occur of (i) five (5) business days following the date on which CVD has delivered to EndoSonics its Hypothetical Returns, or (ii) the date on which the consolidated or combined return is filed. Any Tax Payment required as a result of adjustments to a consolidated or combined state income tax return or any Hypothetical Return, shall be made within five (5) business days of the date that the adjustments giving rise to such Tax Payment have been paid or otherwise become final.

B. Where a Tax Payment required by this Agreement to be made from one party to another is not made within the time provided (or otherwise promptly paid if no time is specified), the amount not timely paid shall bear interest at the rate established pursuant to Section 6621(a)(2) of the Code.

C. Where a Tax Payment is required under the terms of this Agreement as a result of an adjustment to any consolidated or combined state income tax return or a Hypothetical Return, and the amount of the amount of the Tax Payment is not otherwise based on a Tax Liability which includes an interest charge, the amount of the Tax Payment shall bear interest from the date on which the payment would have been due had the consolidated or combined state income tax return and the Hypothetical Returns been originally prepared as so adjusted to the date on which the payment is actually made. The interest shall be computed at the rate established pursuant to Section 6621(a)(2) of the Internal Revenue Code.


7. TERMINATION OF AFFILIATION

A. This Agreement shall survive any termination of affiliation.

B. EndoSonics and CVD shall consult and shall furnish each other with such information as is required to prepare accurately any consolidated or combined state income tax return required or permitted hereunder for any taxable years.

C. EndoSonics and CVD shall also consult and furnish each other with information concerning the status of any tax audit or tax refund claim relating to a taxable year in which the result of such matter could affect the federal or state Tax Liability of the other or which could result in an adjustment of any Tax Payment required hereunder.

8. CONTROL OF AUDITS

A. EndoSonics shall have the exclusive right to control any and all disputes affecting the Tax Liability of EndoSonics and or CVD with respect to any state in which EndoSonics and CVD file consolidated or combined returns, provided that no adjustment of an item of income, gain, loss or deduction shall be reflected on the Hypothetical Returns of CVD prepared in accordance with Paragraph 3.C unless CVD shall have consented to such adjustment in accordance with Paragraph 8.B.

B. In the event that an adjustment is made or proposed to be made to an item of income, gain, loss or deduction reflected in the separate return of CVD and EndoSonics requests CVD to consent to such adjustment, CVD shall not unreasonably withhold consent. For this purpose, consent will be deemed to have been reasonably withheld if CVD has obtained advice of counsel or other tax advisor that the treatment of the item as reported on their separate return is at least as likely as not to be the correct treatment of the item for applicable tax purposes.

C. In the event that CVD withholds consent to any proposed adjustment, CVD shall thereafter bear the costs or resisting such adjustment. If the proposed adjustment can be reasonably separated from other matters involved in the audit without undue cost or delay, CVD shall assume responsibility for disputing the adjustment and shall pay such costs as it may incur in connection with such dispute. If the matter cannot be reasonably separated from other disputed matters which continue to be the subject of dispute, CVD shall pay such costs as are directly traceable to such item.

9. RESOLUTION OF DISPUTES BETWEEN PARTIES

A. The parties shall attempt to resolve any disputes in a manner consistent with the provisions hereof as quickly as possible. To the extent they are unable to do so, and the dispute relates to the calculation or allocation of any tax liability, the matter


shall be referred to a mutually agreeable accounting firm or law firm (the "Firm") for binding arbitration. The parties agree to share equally the expenses of the Firm.

B. Other than with respect to the taxable period that includes the day after the IPO Date, CVD shall have the right to challenge prospectively EndoSonics's decision to include CVD in a Post-IPO-Unitary Return. To the extent CVD and EndoSonics are unable to resolve this issue, it shall be resolved by either (i) seeking a ruling (at the expense of CVD) on this issue; or (ii) referring to the Firm. The standard for decision (other than by ruling) shall be whether it is "more likely than not" that a Unitary Return cannot be filed.

10. MISCELLANEOUS PROVISIONS

A. This Agreement shall become effective on the IPO Date and shall continue in effect until such time as (i) the parties mutually agree to its termination or (ii) there is no longer any possibility that any Tax Payment would be required hereunder. Specifically, this Agreement shall continue in effect for the period described above notwithstanding that EndoSonics and CVD have ceased to file any consolidated or combined state income tax returns.

B. This Agreement contains the entire understanding of the parties hereto with respect to the subject matter contained herein and supersedes all prior written, oral or implied understandings, representations and agreements among the parties with respect thereto except with respect to the agreements attached as appendices hereto which shall continue in effect to the extent provided for herein.

Should all of the Company's outstanding Series A Preferred Stock be, at any time prior to the expiration of this Warrant, converted into shares of the Company's Common Stock in accordance with the Company's Certificate of Incorporation, as amended and/or restated and effective immediately prior to the conversion of all of the Company's Series A Preferred Stock (the "Certificate"), then this Warrant shall immediately become exercisable for that number of shares of the Company's Common Stock equal to the number of shares of Common Stock which would have been received if this Warrant had been exercised in full and the Warrant Stock received thereupon had been simultaneously converted into Common Stock immediately prior to such event. The per share purchase price shall be immediately adjusted to equal the quotient obtained by dividing (x) the aggregate purchase price of the number of shares of Series A Preferred Stock for which this Warrant was exercisable immediately prior to such conversion by (y) the number of shares of Common Stock for which this Warrant is exercisable immediately after such conversion.

C. ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC. In case of any consolidation or merger of the Company with or into any other corporation, entity or person, or any other corporate reorganization, in which the Company shall not be the continuing or surviving entity of such consolidation, merger or reorganization (any such transaction being hereinafter referred to as a "Reorganization"), then, in each case, the holder of this Warrant, on exercise hereof at any time after the consummation or effective date of such Reorganization (the "Effective Date"), shall receive, in lieu of the shares of stock or other securities at any time issuable upon the exercise of the Warrant issuable on such exercise prior to the Effective Date, the stock and other securities and property (including cash) to which such holder would have been entitled upon the Effective Date if such holder had exercised this Warrant immediately prior thereto (all subject to further adjustment as provided in this Warrant).

D. CERTIFICATE AS TO ADJUSTMENTS. In case of any adjustment or readjustment in the price or kind of securities issuable on the exercise of this Warrant, the Company will promptly give written notice thereof to the holder of this Warrant in the form of a certificate, certified and confirmed by the Board of Directors of the Company, setting forth such adjustment or readjustment and showing in reasonable detail the facts upon which such adjustment or readjustment is based.

V. NOTICES OF RECORD DATE, ETC. In the event of

A. any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, or any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property,

B. any capital reorganization of the Company, any reclassification or recapitalization of the capital stock of the Company, or any transfer of all or substantially all the assets of the Company to or consolidation or merger of the Company with or into any other person, or

2.


C. any voluntary or involuntary dissolution, liquidation or winding-up of the Company,

then and in each such event the Company will mail to the holder hereof a notice specifying (i) the date on which any such record is to be taken for the purpose of such dividend, distribution or right, and stating the amount and character of such dividend, distribution or right and (ii) the date on which any such reorganization, reclassification, recapitalization, transfer, consolidation, merger, dissolution, liquidation or winding-up is to take place, and the time, if any is to be fixed, as of which the holders of record of shares of stock or other securities at the time issuable upon the exercise of this Warrant shall be entitled to exchange their shares for securities or other property deliverable on such reorganization, reclassification, recapitalization, transfer, consolidation, merger, dissolution, liquidation or winding-up. Such notice shall be mailed at least twenty (20) days prior to the date therein specified.

VI. EXCHANGE OF WARRANTS. Subject to the transfer condition referred to in the legend endorsed hereon, on surrender for exchange of this Warrant, properly endorsed, to the Company, the Company at its expense will issue and deliver to or on the order of the holder thereof a new Warrant of like tenor, in the name of such holder or as such holder may direct, calling in the aggregate on the face thereof for the number of shares of Series A Preferred Stock called for on the face of the Warrant so surrendered.

VII. REPLACEMENT OF WARRANTS. On receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of any such loss, theft or destruction of this Warrant, on delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of any such mutilation, on surrender and cancellation of such Warrant, the Company at its expense will execute and deliver, in lieu thereof, a new Warrant of like tenor.

VIII. INVESTMENT INTENT. Unless a current registration statement under the Securities Act of 1933, as amended, shall be in effect with respect to the securities to be issued upon exercise of this Warrant, the holder thereof, by accepting this Warrant, covenants and agrees that, at the time of exercise hereof, and at the time of any proposed transfer of securities acquired upon exercise hereof, such holder will deliver to the Company a written statement that the securities acquired by the holder upon exercise hereof are for the own account of the holder for investment and are not acquired with a view to, or for sale in connection with, any distribution thereof (or any portion thereof) and with no present intention (at any such time) of offering and distributing such securities (or any portion thereof).

IX. TRANSFER. Subject to the transfer conditions referred to in the legend endorsed hereon, this Warrant and all rights hereunder are transferrable, in whole or in part, without charge to the holder hereof upon surrender of this Warrant with a properly executed assignment (in the form annexed hereto) at the principal office of the Company. Upon any partial transfer, the Company will at its expense issue and deliver to the holder hereof a new Warrant of like tenor, in the name of the holder hereof, which shall be exercisable for such number or amount of Series A Preferred Stock which were not so transferred.

X. NO RIGHTS OR LIABILITY AS A SHAREHOLDER. This Warrant does not entitle the holder hereof to any voting rights or other rights as a shareholder of the Company. No provisions hereof, in the absence of affirmative action by the holder hereof to purchase Series A Preferred Stock, and no enumeration herein of the rights or privileges of the holder hereof shall give rise to any liability of such holder as a shareholder of the Company.

XI. NOTICES. All notices referred to in this Warrant shall be in writing and shall be delivered personally or by certified or registered mail, return receipt requested, postage prepaid and will be deemed to have been given when so delivered or mailed (i) to the Company, at its principal executive offices

3.


and (ii) to the holder of this Warrant, at such holder's address as it appears in the records of the Company (unless otherwise indicated by such holder).

XII. MISCELLANEOUS. This Warrant and any term hereof may be changed, waived, discharged or terminated only by an instrument in writing signed by the party against which enforcement of such change, waiver, discharge or termination is sought. This Warrant is being delivered in the State of California and shall be governed by and construed and enforced in accordance with the internal laws of the State of California (without reference to any principles of the conflicts of laws). The headings in this Warrant are for purposes of reference only, and shall not limit or otherwise affect any of the terms hereof.
