You should consider carefully the following risk factors, togther with the other information in this Prospectus, before buying any Shares. You should also be aware that certain statements contained in this Prospectus that are not related to historical results are forward-looking statements. These forward-looking statements, such as statements of our strategies, plans, objectives, expectations and intentions, involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements. Uncertain market acceptance of Fibre Channel technology Our current products are all designed to comply with the Fibre Channel standard for data communications. Therefore, our success depends on the market acceptance of the Fibre Channel standard. Our products have historically sought to compete in the high performance local area network ("LAN") market. Our current effort is to deploy our products as switching devices in high performance storage area network ("SAN") markets. We have decided to focus the majority of our marketing and sales efforts on the SAN market. In the SAN market, adoption of Fibre Channel technology requires computer systems manufacturers to convert from the Small Computer System Interface interconnect protocol currently being used by many manufacturers. While many computer systems manufacturers have announced their intentions to convert to Fibre Channel as the standard for their products, we cannot assure you that they will. Nor can we assure you that manufacturers who have not announced their intentions will adopt the Fibre Channel standard. Even if Fibre Channel becomes a widely adopted standard, we cannot assure you that manufacturers will incorporate our products into the products they make. In the LAN market, Fibre Channel competes with a number of other network technologies which are more established than Fibre Channel. We do not plan to emphasize the LAN market for future sales Competition in the Fibre Channel market Our Fibre Channel products must compete with Fibre Channel products of other companies. For example, Brocade Communications Systems, Inc., Vixel, and McData have developed Fibre Channel switches. Other companies may also be developing switches. In addition, a number of companies, including Emulex Corp., Q Logic Corp., Jaycor Corp., Gadzoox Corp., G2 Corp. and Interphase Corp., are developing, or have developed, Fibre Channel products other than switches, such as adapters or hubs. We anticipate that these and other companies will introduce commercial Fibre Channel products in the near future. In the event that Fibre Channel technology gains wider market acceptance, it is likely that an increasing number of competitors will begin developing and marketing Fibre Channel products. Some of the companies that produce or may produce competitive Fibre Channel products have substantially greater financial, technological and marketing resources than Ancor. We may not be able to compete effectively against current or future competitors. Our competitors may succeed in adapting more rapidly and effectively to changes in technology or the market. Our competitors may develop or market products that will be more widely accepted than ours. If we fail to compete effectively, it would prevent us from generating sufficient sales to allow us to attain profitable operations. Dependence on Fibre Channel switches and ASICs We currently market only Fibre Channel switches and application specific integrated circuits ("ASICs"), and do not market other Fibre Channel products such as interface adapters. In the past, we have designed, manufactured and marketed interface adapters, but we no longer do so. There may be some future sales of previously developed interface adapters, but we expect that the sales will be small. As a result, we must derive all of our sales from Fibre Channel switches or ASICs. Although ASICs can either be sold as components for other companies' products or -3- the underlying technology can be licensed to other companies, we have not sold any ASICs as components and have only licensed the underlying technology to one company. Risk of technological obsolescence The data network communications and storage markets experience rapid technological change, including changes in customer requirements, frequent new product introductions and enhancements, and evolving industry standards. Our success depends in part on our ability to keep pace with technological developments and emerging industry standards. We must also respond to customer requirements by enhancing our current products and developing and introducing new products. If we fail to anticipate or respond rapidly to advances in technology by adapting our products appropriately, our products could become obsolete. If our products become obsolete, it would have a material adverse effect on our business, financial condition and results of operations. Product development risks Our success depends in part on our ability to develop and introduce product enhancements and new products. The success of any product enhancement or new product depends on many factors, including the amount of resources devoted to its development, product competition and marketing campaigns. We may not succeed in developing, introducing and marketing any product enhancements or new products. We cannot assure you that if we introduce new products they will gain market acceptance. Our failure to develop or introduce enhancements or new products, or significant delays in doing so, could have a material adverse effect on our business, financial condition and results of operations. Products as complex as ours frequently contain undetected hardware or software errors ("bugs") when first introduced or as new versions are released. Despite our testing and quality control efforts, we anticipate that errors may be found from time to time in our new or enhanced products after commercial introduction. In addition, errors may occur when our products are integrated with products of other companies which are designed to interoperate with our products. If we are unable to easily fix any errors it could result in the following and other consequences: o delay or loss of market acceptance of our products; o possible warranty expense; o diversion of engineering and other resources from product development efforts; o the loss of credibility in the market. Any of these consequences could have a material adverse effect on our business, financial condition and results of operations. Uncertainty of future profitability We have incurred net losses in each of the past three years and, at December 31, 1998, we had an accumulated shareholders' deficit of approximately $41.6 million. We have incurred operating losses of $14.5 million for the twelve months ended December 31, 1998. Net losses for the years ended December 31, 1996 and 1997 were approximately $5.3 million and $9.8 million, respectively. Future operating results will depend on many factors, including the growth of the Fibre Channel market, demand for our products, the level of product and price competition, our ability to develop and market new products, general economic conditions and other factors. We cannot assure you that we will achieve or sustain profitability in the future. As a result of our switch in focus from the LAN market to the SAN market and general economic conditions in Japan (where one of our largest customers is located), we must develop relationships with new customers to generate significant revenues in the future. -4- Risk of product returns We have allowed customers to return our products to us because we feel it is necessary to make concessions to customers during the initial introduction of a new technology product. During 1998 we fully used our allowances for product returns. We can not assure you that significant returns will not occur in the future. Any future returns could have a material adverse effect on our business, financial condition and results of operation. Dependence on certain customers A significant portion of our revenues have been generated by three customers. Hucom, Inc. generated 4% of our revenue in 1998, 88% in 1997, and 41% in 1996. Netmarks, Inc. generated 22% of our revenue in 1998. Additionally, Boeing Company generated 50% of our revenue in 1998, 9% in 1997, and 1% in 1996. A significant portion of products sold to Hucom, Inc. and Netmarks, Inc., our Japanese distributors, in 1998, 1997 and 1996 were to one end user. In future periods, our Japanese distributors' sales of our products to this specific end user are expected to decline from current levels. Additionally, general economic conditions in Japan make future sales to our Japanese distributors uncertain. If any of our large customers reduced their purchases of our products, it would have a material adverse effect on our business, financial condition and results of operation. Our revenues in the future may also be generated by a small number of significant customers. Lack of OEM selling experience To succeed in the SAN market, we will need to sell directly to original equipment manufacturers ("OEMs"). We have sold our products in the past either directly to end users or through resellers. Only recently have we sold our products to OEMs and, therefore, we have limited experience selling our products through this channel. We cannot assure you that we will be successful selling our products to OEMs. Risks associated with managing growth The anticipated growth of our operations will place significant strain on our management, sales and marketing, manufacturing, operating and financial systems resources. If our business grows, we may encounter the following difficulties and others: o lower than projected production rates; o lower quality control and assurance; o decreased product reliability; o increased manufacturing costs; o difficulties in maintaining internal accounting controls; o malfunctioning of existing and new equipment; o insufficient or untimely component supplies; o shortages of personnel. We may not be able to successfully plan for, or manage increased production and marketing of, our products. Our failure to do so could have a material adverse effect on our business, financial condition and results of operations. Dependence on subcontractors We subcontract a majority of our production activities, including the manufacture, assembly and testing of our proprietary Fibre Channel switch designs. We depend on subcontractors to deliver high quality products in a timely manner, but we cannot assure you that they will. Poor performance by one of our subcontractors would have a material adverse effect on us until we could find an alternate subcontractor. We cannot assure you that we would be able to find an alternate subcontractor to deliver quality products at an acceptable price. Therefore, if we -5- experience problems with one of our subcontractors, it will likely have a material adverse effect on our business, financial condition and results of operations. Dependence on suppliers and availability of components Some of the components we use in our products are available only from a single supplier, or from a limited number of suppliers. Other components may from time to time be in short supply or temporarily be available from only a single supplier. The following factors could each have a material adverse effect on our ability to produce and market our products: o scarce quantities of components; o a reduction or interruption in component supply; o a disruption of existing supplier relationships; o an inability to develop alternative sources; o a significant increase in the price of components. Need to attract and retain key personnel Our success depends on our ability to attract and retain highly trained personnel for such areas as management, sales and engineering. In particular, our success will depend in part on the continued service of Mr. Ken Hendrickson, our Chief Executive Officer, Mr. Calvin G. Nelson, our President, and Mr. Steven E. Snyder, our Chief Financial Officer. As we increase our production and sales levels, we will need to attract and retain additional qualified skilled and unskilled workers for our operations. In recent years there has been great demand for qualified skilled and unskilled employees in the Minneapolis area, where our main operations are located. We can give no assurance that we will be successful in attracting and retaining the personnel needed for our business. Any failure to do so would adversely affect our business, financial condition and results of operations. Dependence on intellectual property Our success will depend in part on our ability to protect our proprietary rights and to operate without infringing on the proprietary rights of others. We currently hold one U.S. patent covering certain aspects of one of our Fibre Channel switches. This patent will expire February 6, 2007. We have applied for additional patents and may apply for additional patents in the future. We cannot assure you that any of our future patent applications will result in issued patents, or that the scope of any current or future patents will prevent competitors from introducing competitive products. There is also a risk that any current or future patents issued to us would not be enforceable if challenged. In addition, other parties may hold or receive patents that contain claims covering other technology included in our current or future products that could hinder or prevent the sale of our products or require us to obtain licenses to such technology. Such licenses might not be available on acceptable terms or at all. In addition to patents, the source code for the software contained in our products is protected by copyright law. We also rely upon unpatented trade secrets, the know-how and expertise of our employees and on non-disclosure and confidentiality agreements with our employees, vendors and customers. Although we believe that we have been careful to protect our unpatented proprietary rights, we cannot assure you that our measures will be sufficient to protect our rights against third parties. Likewise, we cannot assure you that others will not independently develop or otherwise acquire unpatented technologies or products similar or superior to ours. We have registered four trademarks with the United States Patent and Trademark Office and have filed for registration of four additional marks in which we claim trademark rights, one of which has been allowed. United States trademark rights are acquired by use rather than by registration, and we cannot assure you that others do not have conflicting or superior rights to our unregistered trademarks. We cannot assure you that any of the trademarks covered by our applications for registration will be found registrable, that registrations will issue, or that we can support the cost of defense of our trademarks. -6- The high technology area frequently features disputes over intellectual property. We may be required to defend our intellectual property rights against infringement, duplication and discovery by third parties or to defend ourselves against third-party claims of infringement. Likewise, disputes may arise with respect to ownership of technology developed by employees who were previously employed by other companies. Any such litigation or disputes could result in substantial costs. An adverse determination could subject us to significant liabilities to third parties, require us to seek licenses from or pay royalties to third parties or require us to develop appropriate alternative technology. We can give no assurance that any such licenses would be available on acceptable terms or at all, or that we could develop alternate technology at an acceptable price or at all. Any of these events could have a material adverse effect on our business, financial condition and results of operations. Quarterly operating results are subject to fluctuation Our quarterly revenue and operating results have varied in the past and can be expected to vary in the future. In the future, our operating results may vary significantly from quarter to quarter due to such factors as: o changes in customer buying patterns; o the timing of the announcement and introduction of new products by Ancor or our competitors; o the tactics of our competitors; technological developments affecting the data communication network market; o the overall strength of the economy; uncertainties associated with the introduction of any new product or product enhancement; o gauging ultimate customer demand; o predicting general trends in the market for our products. Fluctuations in our quarterly operating results or our failure to meet analysts' projections or public expectations as to results may adversely affect the market price of our stock. Our operating results for any particular quarter are not necessarily indicative of results that we may achieve for any subsequent quarter or full fiscal year. Stock price volatility Like other technology companies, our stock price may be volatile. We may experience volatility in our stock price due to the following and other factors: o quarterly variations in our operating results; o the liquidity of the market for our stock; o announcements of business developments by Ancor or our competitors; o public perception regarding Fibre Channel's market status; o developments or disputes concerning proprietary rights; o technological innovations or newly introduced products; o general conditions in the data communications network industry and the economy. Future capital needs; uncertainty of additional funding We anticipate that cash on hand and anticipated revenues from operations will be sufficient to finance our operations at least through December 1999. However, we may require additional capital sooner than December 1999. In order to meet our needs beyond such time, we may be required to raise additional capital. Additional capital may be unavailable, or available only on unfavorable terms. Any additional equity financings may be dilutive to purchasers in this offering. Any debt financing may involve restrictive covenants. Failure to secure additional financing if and when needed could adversely affect our operations. If we are unable to raise additional capital we would be required to delay, scale back, or eliminate market expansion activities and research and development on existing or new products, or cease operations entirely. -7- Year 2000 risks We have completed an assessment of Year 2000 compliance for our critical operating and application systems. We have determined that through normal recurring system upgrades, the vast majority of our systems are currently, or will be by early 1999, Year 2000 compliant. In 1996 we purchased an enterprise-wide information system from a world-wide supplier and developer of information systems. The developer of this information system has provided its clients written assurance that the system will correctly function across the year 2000, as verified by previous system tests and Year 2000 certification by the International Technology Association of America. Additionally, our products, including software, are not date sensitive as to functionality. The costs of becoming Year 2000 compliant has not had and is not expected to have a material effect on our financial position, operations or cash flow because compliance has largely been the result of normal system upgrades. We cannot assure you that the Year 2000 issue will be properly addressed by customers, vendors, service utilities, government and other external entities. We are communicating with these parties to determine how they are addressing the Year 2000 issue and to evaluate any likely impact on us. We have requested commitment dates from these parties as to their Year 2000 readiness. This process will continue in fiscal 1999. The efforts of third parties are not within our control, however, and their failure to remedy Year 2000 issues successfully could result in business disruption, loss of revenue and increased operating cost. At the present time, it is not possible to determine whether any such events are likely to occur, or to quantify any potential negative impact they may have on our future results of operations and financial condition. We have not established contingency plans, but expect to assess our need for contingency plans during 1999. The foregoing discussion regarding Year 2000 contains forward-looking statements which are based on management's best estimates derived using various assumptions. These forward-looking statements involve inherent risks and uncertainties, and actual results could differ materially from those contemplated by such statements. Factors that might cause material differences include, but are not limited to, (i) our ability to obtain alternative manufacturing sources should our current sources' operations be disrupted due to Year 2000 complications, and (ii) our ability to respond to unforeseen Year 2000 complications. Such material differences could result in, among other things, business disruption, operational problems, financial loss, legal liability and similar risks. Inventory obsolescence We operate in a market characterized by rapid technological change. Our existing inventory could become obsolete due to changes in customer requirements, frequent new product introductions and enhancements, and evolving industry standards. These events may materially and adversely affect our business, financial conditions and results of operations. Anti-takeover provisions Provisions of our amended and restated articles of incorporation, Minnesota law and our Shareholders' Rights Plan could make it more difficult for a third party to acquire us, even if doing so would be beneficial to our shareholders. No dividends We have never declared or paid any cash dividends on our capital stock and do not anticipate paying any cash dividends in the forseeable future. -8- WHERE YOU CAN FIND MORE INFORMATION We file annual, quarterly and special reports, proxy statements and other information with the SEC.

Fibre Channel is a high bandwidth, low latency advance in data storage communications technology, developed under the auspices of the American National Standards Institute ("ANSI"), currently enabling the transfer of data at speeds of one Gigabit per second. We develop, manufacture, and market Fibre Channel switches and application specific integrated circuits ("ASICs"). Since our inception, our core technology has been built around the utilization of fiber optic cable for data transmission. In 1992, we delivered our first prototype Fibre Channel products, and commercial deliveries began in 1993. Our Fibre Channel products are used by organizations worldwide for enhanced network performance, scalability and connectivity. Today Ancor -- an active member of the ANSI Fibre Channel committee and the Fibre Channel Association -- focuses entirely on the development of Fibre Channel solutions. Prior to 1998, we focused our business and products on the local area network ("LAN") market, developing and marketing Fibre Channel switches and adapter cards for the LAN market. However, in 1998 we completed the refocusing of our business and our Fibre Channel products from the local area network market to the storage area network ("SAN") market. With Gigabit Ethernet the technology of choice for local area networks and with high quality, low-cost Fibre Channel host adapters now available from other sources, we discontinued that portion of our business to intensify our pursuit of the emerging Fibre Channel SAN market. Over the last decade, applications and computer processing performance have increased by many orders of magnitude. Additionally, with computer networks running more business critical applications, access to, and availability of, the associated data is strategic to business operations. Historically, the devices storing the required data were directly attached to individual servers on the LAN. However, LAN data paths often do not have the necessary performance to address storage requirements, resulting in network bottlenecks and overall system degradation. Thus, separate networks of storage devices are being developed. A SAN is a dedicated network optimized for storage-related functions over which information is permitted to be accessed, managed, and shared among various storage devices and servers. Although SANs are usually connected to the more widely accessed LAN, the SAN operates complementary to the LAN. Overall enterprise network performance improves because the LAN is free from the cumbersome overhead associated with file access, retrieval, storage, and data backup functions which place significant demands on network bandwidth. These functions are instead more effectively and efficiently performed by a network optimized for the demands of storage functions. The components of a typical SAN are software to manage and control the SAN, storage devices, network interface cards which are inserted into the servers, and a hub or switch to facilitate the interconnection between the servers and storage devices. We develop and market Fibre Channel switches. We currently sell Fibre Channel switches under the Gigworks trademark. During 1998 we introduced our GigWorks MKII 8-port switch, complementing our MKII 16-port switch and previous-generation switches. Our current switches enable very large SANs to be built by linking multiple switches in 8 and 16 node increments. Through the Fibre Channel switch, users are able to establish multiple simultaneous connect links. We have also developed ASICs which are a component of our switches, but which may be sold as separate products. Our ASICs provide building blocks at the chip level for implementing Fibre Channel technology. These ASICs combine a number of Fibre Channel functions in a single chip and thereby substantially reduce the number of components needed to implement Fibre Channel switches. Although our ASICs may be sold as a separate product, we have not done so in recent years. We have, however, licensed the use of the ASIC to a third party, and may sell our ASICs as a separate product in the future. -10- Our principal executive offices are located at 6130 Blue Circle Drive, Minnetonka, Minnesota 55343, (telephone number (612) 932-4000).

Indemnification of Directors and Officers Article eight of our Second Amended and Restated Articles of Incorporation provides that a director shall not be liable to us or our shareholders for monetary damages for a breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to us or our shareholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Sections 302A.559 or 80A.23 of the Minnesota Statutes, (iv) for any transaction from which the director derived an improper personal benefit, or (v) for any act or omission occurring prior to the date when such Article eight became effective. Our Restated Bylaws provide that our officers and directors and certain others will be indemnified to substantially the same extent permitted by Minnesota law. Section 302A.521 of the Minnesota Business Corporation Act provides that a corporation shall indemnify any person who was or is made or is threatened to be made a party to any proceeding, by reason of the former or present official capacity (as defined) of such person, against judgments, penalties, fines, settlements and reasonable expenses, including attorneys' fees and disbursements, incurred by such person in connection with the proceeding if certain statutory standards are met. "Proceeding" means a threatened, pending or complete civil, criminal, administrative, arbitration or investigative proceeding, including one by or in the right of the corporation. Section 302A.521 contains detailed terms regarding such right of indemnification and reference is made to that section for a complete statement of such indemnification rights. We maintain a standard policy of officers' and directors' insurance. Item 16. List of Exhibits 5 Opinion of Dorsey & Whitney LLP 23.1 Consent of KPMG Peat Marwick LLP 23.2 Consent of McGladrey & Pullen, LLP 23.3 Consent of Dorsey & Whitney LLP (included in Exhibit 5 to this Registration Statement) 24 Power of Attorney (included on signature page of this Registration Statement) Item 17. Undertakings The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change in the information set forth in the registration statement; Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the registration statement is on Form S-3 or Form S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) That, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement 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. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, 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 Act and is, therefore, unenforceable. In the event that a claim for indemnification against 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, 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 whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. II-2 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Minneapolis, State of Minnesota, on April 1, 1999.
