While we have included what we believe to be the most important information about the company and this offering, the following summary may not contain all the information that may be important to you. You should read this entire prospectus carefully, including the risks of investing discussed under “Risk Factors” beginning on page 2, the financial statements and related notes, and the information to which we refer you and the information incorporated into this prospectus by reference, for a complete understanding of our business and this offering. References in this prospectus to “our company,” “we,” “our,” “Solexa” and “us” refer to Solexa, Inc. Reference to “selling stockholders” refers to those stockholders listed herein under Selling Stockholders, who may sell shares from time to time as described in this prospectus.
Solexa, Inc.
      We are in the business of developing and commercializing genetic analysis technologies. We are currently developing and preparing to commercialize a novel instrumentation system for genetic analysis based on our Sequencing-by-Synthesis, or SBS, chemistry and the DNA “cluster” technology we acquired in 2004. This platform is expected to support many types of genetic analysis, including DNA sequencing, gene expression, genotyping and micro-RNA analysis. We believe that this technology, which can potentially generate over a billion bases of DNA sequence from a single experiment with a single sample preparation, will dramatically reduce the cost, and improve the practicality, of human re-sequencing relative to conventional technologies. We anticipate launching our first generation whole-genome sequencing system by the end of 2005. We believe our new DNA sequencing system will enable us to implement a new business model based primarily on the sales of genomic sequencing equipment, reagents and services to end user customers. Our longer-term goal is to further reduce the cost of human re-sequencing to a few thousand dollars for use in a wide range of applications from basic research through clinical diagnostics.
      We incorporated in the state of Delaware in February 1992. In March 2005, we completed the combination of our company with Solexa Limited, a company registered in England and Wales, and changed our name from Lynx Therapeutics, Inc. (“Lynx” or the “Company”)to Solexa, Inc. Our principal executive offices are located at 25861 Industrial Blvd., Hayward, CA 94545. Our telephone number is (510) 670-9300.

RISK FACTORS
Investment in our shares involves a leader in the development and applicationhigh degree of novel genomics analysis solutions that provide comprehensive and quantitative digital gene expression information important to modern systems biology research in the pharmaceutical, biotechnology and agricultural industries. These solutions are based on Megaclone and Massively Parallel Signature Sequencing, or MPSS™, Lynx’s unique and proprietary cloning and sequencing technologies. Gene expression refersrisk. In addition to the number of genes and the extent a cell or tissue expresses those genes, and represents a way to move beyond DNA sequence data to understand the function of genes, the proteins that they encode and the role they playother information in health and disease. Systems biology is an approach in which researchers seek to gain a complete molecular understanding of biological systems in health and disease.

RISK FACTORS

Youthis prospectus, you should carefully consider the following risk factors, in addition to other information included or incorporated by reference in this prospectus,risks described below, which we believe are the material risks we face, before making an investment decision. Additional risks that we do not yet know of or that we currently think are immaterial may also impairpurchasing our business operations.common stock. If any of the events or circumstances described in the following risks actually occurs, our business may suffer,could be materially harmed, and our financial condition and results of operations could be materially and adversely affected. As a result, the trading price of our common stock could decline, and you might lose all of your investment. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties, not presently known to us, or that we currently see as immaterial, may also harm our business. If any of these additional risks and uncertainties occurs, the trading price of our common stock could decline, and you might lose all or part of your investment.

We have a history of net losses. We expect to continue to incur net losses, and we may not achieve or maintain profitability.

We have a history of net losses, expect to continue to incur net losses and may not achieve or maintain profitability.
      We have incurred net losses each yearyears since our inception in 1992, including1992. In addition, Solexa Limited, a wholly owned subsidiary, has incurred net losses of approximately $8.8 millioneach year since its inception in 1998, including a net loss for the yearthree months ended DecemberMarch 31, 2003, $15.5 million in 2002 and $16.7 million in 2001.2005. As of December 31, 2003,2004 we had an accumulated deficit of approximately $107.7$28.0 million. Net losses for the combined company may continue for at least the next several years as we proceedthe combined company proceeds with the development and commercialization and additional development of ourits technologies. The presence and size of these potential net losses will depend, in part, on the rate of growth, if any, in our revenues and on the level of our expenses. Our researchResearch and development expenditures and general and administrative costs have exceeded our revenues to date. Researchdate, and developmentthese expenses may increase due to spending for ongoing technology development and implementation, as well as new applications.in the future. We will need to generate significant additional revenues to achieve profitability. Evenprofitability, and even if we do increaseare successful in achieving profitability, there is no assurance we will be able to sustain profitability.
We will need to raise additional funding, which may not be available on favorable terms, if at all.
      We will need to raise additional capital through public or private equity or debt financings in order to satisfy our revenuesprojected capital needs.
      The amount of additional capital we will need to raise depends on many factors, including:
• the progress and scope of research and development programs;
• the progress of efforts to develop and commercialize new products and services, and
• the costs involved in preparing, filing, prosecuting, maintaining and enforcing patent claims and other intellectual property rights.
      We cannot be certain that additional capital will be available when and achieve profitability,as needed or that our actual cash requirements will not be greater than anticipated. If we require additional capital at a time when investment in biotechnology companies or in the marketplace in general is limited due to the then prevailing market or other conditions, we may not be able to sustain profitability.raise such funds at the time that we desire or any time thereafter. If we are unable to obtain financing on terms favorable to us, we may be unable to execute our business plan and may be required to cease or reduce development or commercialization of our products, to sell some of all of our technology or assets or to merge with another entity.
We may not realize the benefits we expect from the combination of Solexa Limited and Solexa.
      The integration of Solexa Limited and Solexa will be complex, time consuming and expensive, and may disrupt our business. We will need to overcome significant challenges in order to realize any benefits or synergies from the combination of Solexa Limited and Solexa. These challenges include the timely, efficient and successful execution of a number of post-transaction events.
      We may not succeed in addressing these risks or any other problems encountered in connection with the combination. The inability to successfully integrate the operations, technology and personnel of Solexa

     Our2


Limited and Solexa, or any significant delay in achieving integration, could hurt our business and, as a result, the market price of our common stock.
If management is unable to effectively manage the increased size and complexity of the combined company, our operating results will suffer.
      On March 4, 2005, Solexa Limited’s 60 employees based outside of Cambridge, U.K. were added to our existing 75 employees based in Hayward, California. As a result we will face challenges inherent in efficiently managing an increased number of employees over large geographic distances, including the need to implement appropriate systems, financial controls, policies, standards and benefits and compliance programs. The inability to successfully manage the substantially larger and internationally diverse organization, or any significant delay in achieving successful management, could hurt our business.
We have a new management team that may not be able to define or execute on our business plan.
      Effective March 4, 2005, John West was named our chief executive officer. Mr. West has been the chief executive officer of Solexa Limited since August 2004. Effective March 10, 2005, Peter Lundberg was named our vice president and chief technical officer. Effective March 31, 2005, Linda Rubinstein was named our vice president and chief financial officer. In addition we anticipate hiring during 2005 to fill executive positions in marketing and manufacturing. While Mr. West has experience managing private genomics companies and large genomics teams within public U.S. companies, he has not previously been chief executive of a public company in the U.S. Mr. West anticipates dividing his time between our operations in California and our operations in the U.K. for the foreseeable future. These executives are new to our company and may not be effective, individually or as a group, in executing our business plan, and our operating results may suffer as a result.
We could lose key personnel, which could materially affect our business and require us to incur substantial costs to recruit replacements for lost personnel.
      As a result of the combination, current and prospective employees of the combined company could experience uncertainty about their future roles within the combined company. Any of our key personnel could terminate their employment, sometimes without notice, at any time. People key to the operation and management of the combined company are John West, our chief executive officer; Peter Lundberg, our vice president and chief technical officer, Linda Rubinstein, our vice president and chief financial officer, and Tony Smith, our vice president and chief scientific officer. We are also highly dependent on the principal members of our scientific staff. The loss of any of these persons’ services might adversely impact the achievement of our objectives and the continuation of existing customer, collaborative and license agreements. In addition, recruiting and retaining qualified scientific personnel to perform future research and development work will be critical to our success. There is currently a shortage of skilled executives and employees with technical expertise, and this shortage is likely to continue. As a result, competition for skilled personnel is intense and turnover rates are high. Competition for experienced scientists from numerous companies, academic and other research institutions may limit our ability to attract and retain such personnel.
Our company’s officers, and directors and their affiliated entities have substantial control over the company.
      As of July 12, 2005, our company’s executive officers, directors and entities affiliated with them, in the aggregate, beneficially own approximately 72.4% of the combined company, including warrants issued in the private placement not currently exercisable within 60 days of July 12, 2005. These stockholders, if acting together, would be able to influence significantly all matters requiring approval by our stockholders, including the election of directors and the approval of mergers or other changes in corporate control.

We intend to implement a business model that is unproven and different from our former business model.
      Our current business model is based primarily on the planned sales of genomic sequencing equipment and future sales of reagents and services to support customers in their use of that equipment. Our historical business model was based on providing genomics services using our MPSS technology and supplying customers with DNA sequences and other information that result from experiments. A change in emphasis from our former business model may cause our current customers to delay, defer or cancel any purchasing decisions with respect to new or existing agreements. To date, we have not been contacted by any current customer with respect to any such delay, deferral or cancellation of any existing agreement. There is no assurance that we will be successful in changing the emphasis of our business model from providing sequencing services to selling equipment, reagents and support services to new or existing customers.
It is uncertain whether we will be able to successfully develop and commercialize our new products or to what extent we can increase our revenues or become profitable.
      We set out to develop new genomics sequencing technologies and we are now using those technologies to develop new equipment, reagents and services. If our strategy does not result in the development of products that we can commercialize, we will be unable to generate revenuessignificant revenues. Although we have developed DNA sequencing machines and achieve profitabilityprovide gene expression services to customers with our machines, these were based on the MPSS technology that we previously developed rather than the new technologies under development. We cannot be certain that we can successfully develop any new products or that they will receive commercial acceptance, in which case we may not be able to recover our investment in the product development.
We will need to develop manufacturing capacity by ourselves or with a partner.
      If we are successful in achieving market acceptance for our new DNA analytical instruments, we will need either to build internal manufacturing capacity or to contract with a manufacturing partner. There is no assurance that we will be able to build manufacturing capacity internally, or to find a manufacturing partner, to meet both the volume and quality requirements necessary to be successful in the market. Any delay in establishing or inability to expand our manufacturing capacity could hurt our business.
Our technology platform is at the development stage and is unproven for market acceptance.
      While some of our gene expression technology has been commercialized and is currently in use, we are developing additional technologies to generate information about gene sequences that may enable scientists to better understand complex biological processes. These technologies are still in development, and we may not be able to successfully complete development of these technologies or to commercialize them. Our success depends on many factors, including:

our ability to continue existing customer relationships and enter into additional corporate collaborations and agreements;

• technical performance of our technologies in relation to competing technologies;
• the acceptance of our technology in the market place;
• the ability to establish an instrument manufacturing capability, or to obtain instruments from another manufacturer; and
• the ability to manufacture reagents and other consumables, or obtain licenses to resell reagents and other consumables.

our ability to expand the scope of our products and services into new areas of pharmaceutical, biotechnology and agricultural research;

our customers’ and collaborators’ abilities to develop diagnostic, therapeutic and other commercial products from the application of our technologies; and

the successful clinical testing, regulatory approval and commercialization of such products by our customers and collaborators.

     The time required to reach profitability is highly uncertain. We may not achieve profitability on a sustained basis, if at all.

We will need additional funds in the future, which may not be available to us.

     We have invested significant capital in our scientific and business development activities. Our future capital requirements will be substantial as we conduct our operations, and will depend on many factors including:

the progress and scope of our research and development projects;

payments received under our customer, license and collaborative agreements;

our ability to establish and maintain customer, license and collaborative arrangements;

1


the progress of the development and commercialization efforts under our customer, license and collaborative agreements;

the costs associated with obtaining access to biological samples and related information; and

the costs involved in preparing, filing, prosecuting, maintaining and enforcing patent claims and other intellectual property rights.

     We have experienced losses since our inception, including a net loss of $8.8 million for the year ended December 31, 2003. Net losses may continue for at least the next several years as we proceed with the commercialization and additional development of our technologies. The presence and size of these potential net losses will depend, in part, on the rate of growth, if any, in our revenues and on the level of our expenses. Our cash and cash equivalents have decreased from $11.7 million as of December 31, 2002. As of December 31, 2003, our cash and cash equivalents were $5.6 million, which includes restricted cash of $0.7 million. In March 2004, the Company raised $4 million from a private placement of its common stock, and reduced its headcount by 15% to 76 employees. We believe that with the funds raised in March 2004, our current cash, cash equivalents and restricted cash, along with cashflows to be generated from customers, collaborators and licensees will be sufficient to enable us to meet our projected operating and capital requirements through at least December 31, 2004. We may seek additional financing, as needed, through arrangements with customers, collaborators and licensees and equity or debt offerings. If we raise additional capital by issuing equity or convertible debt securities, our existing stockholders may experience substantial dilution. There can be no assurance that additional financing will be available on satisfactory terms, or at all. If we are unable to secure additional financing on reasonable terms, or are unable to generate sufficient new sources of revenue through arrangements with customers, collaborators and licensees, we will be forced to take substantial restructuring actions, which may include significantly reducing our anticipated level of expenditures, the sale of some or all of our assets, or obtaining funds by entering into financing or collaborative agreements on unattractive terms, or we will not be able to fund operations.

Our technologies are new and unproven and may not allow our customers, collaborators or us to identify genes, proteins or targets for drug discovery.

      You must evaluate us in light of the uncertainties and complexities affecting an early stage genomicsgenetic analysis company. Our technologies are new and unproven. The application of theseour technologies is in too early a stage to determine whether itthey can be successfully implemented. These technologies assume that information about gene expression and gene sequences may enable scientists to better understand complex biological processes and, therefore, provide us with increased commercial opportunities for our products. Our technologies also depend on the successful integration of independent technologies, each of which has its own development risks. Relatively few therapeutic products based on gene discoveries have beenFurthermore, we are anticipating that, if our technology is able to successfully developed and commercialized.

There is no guarantee, even if our technology is able to successfully reduce the cost of genetic analysis relative to existing providers, that we will be able to induce customers collaboratorswith installed bases of conventional genetic analysis instruments to purchase our system or us to identify genes, proteins or targetsexpand the market for drug discovery.

We do notcompanies. At present, our services business constitutes generates substantially all of our revenues.

If we cannot negotiate additional collaborative arrangementsare successful in commercializing our genetic analytical instrument systems, we anticipate continuing to provide genetic analysis services after the commercial launch of our genetic analysis instrument systems to meet particular customer requirements, but also to support the marketing of our instruments by, for example, allowing potential systems customers to understand how our instrumentation performs on their samples of interest. There is no guarantee, however, that our service business will generate positive cash flow or contractsbecome profitable. Furthermore, unless and until we are able to commercialize our new genetic analytical instrument systems under development, we will be dependent on acceptable terms,a small number of customers to continue our current services business, and the loss of one or at all, or if such collaborations or relationships are not successful,more of those customers could harm our results of operations.
      Prior to our business combination with Solexa Limited, we may never become profitable.

     We have derived substantially all of our revenues from corporate collaborations, customer agreements and licensing arrangements. Revenues from such agreements depend upon continuation of the related relationships,to our performance of genomics discovery services the achievement of milestones and royalties derived from future products developed from our research and technologies. To date, we have received, and expect to continue to receive in the future, abusiness. A significant portion of our revenues came from a small number of collaborators, customers and licensees, as shown on the following table:

     Iflicensees. Thus, until we failare able to perform genomics discovery services or successfully achieve milestones orcommercialize our collaborators fail to develop successfulnew products under development, we will not earn the revenues contemplated under such agreements. If our collaborators, customers or licensees do not renew existing agreements, we lose one of these collaborators, customers or licensees, we do not attract new collaborators, customers or licensees or we are unable to enter into new collaborative, customer or license agreementsbe dependent on commercially acceptable terms, our revenues may decrease, and our activities may fail to lead to commercialized products.

     Our dependence on collaborations, agreements or licenses with third parties subjects us to a small number of risks. We have limitedcustomers to continue our current business, and the loss of one or no control over the resources that such third parties may choose to devote tomore of those customers could harm our joint efforts. Our collaborators, customers or licensees may breach or terminate their agreements with us or fail to perform their obligations thereunder. Further, our collaborators, customers or licensees may elect not to develop products arising outresults of our agreements or may fail to devote sufficient resources to the development, manufacture, marketing or sale of such products. While we do not currently compete directly with any of our customers and collaborators, some of our customers and collaborators could become our competitors in the future if they internally develop DNA analysis technologies or if they acquire other genomics companies and move into the genomics industry. We will not earn the revenues contemplated under our customer and collaborative arrangements, if our customers and collaborators:

We operate in an intensely competitive industry with rapidly evolving technologies, and our competitors may develop products and technologies that make ours obsolete.

develop competing products;

preclude us from entering into collaborations with their competitors;

fail to obtain necessary regulatory approvals; or

terminate their agreements with us.

We depend on a single supplier to manufacture flow cells used in our MPSS technology.

     Flow cells are glass plates that are micromachined, or fabricated to very precise, small dimensions, to create a grooved chamber for immobilizing micro-beads in a planar microarray, which is a two-dimensional, dense ordered array of DNA samples. We use flow cells in our MPSS technology. We currently purchase the flow cells used in our MPSS technology from a single supplier, although the flow cells are potentially available from multiple suppliers. While we believe that alternative suppliers for flow cells exist, identifying and qualifying new suppliers could be an expensive and time-consuming process. Our reliance on outside vendors involves several risks, including:

the inability to obtain an adequate supply of required components due to manufacturing capacity constraints, a discontinuance of a product by a third-party manufacturer or other supply constraints;

reduced control over quality and pricing of components; and

delays and long lead times in receiving materials from vendors.

We operate in an intensely competitive industry with rapidly evolving technologies, and our competitors may develop products and technologies that make ours obsolete.

      The biotechnology industry is highly fragmented and is characterized by rapid technological change. In particular, the areaareas of genetic analysis platforms and genomics research is aare rapidly evolving field.fields. Competition among entities attempting to identify genes and proteins associated with specific diseases and to develop products based on such discoveriesdeveloping genetic analysis systems is intense. Many of our competitors have substantially greater research and product development capabilities and financial, scientific and marketing resources than we do.

     We

      In our genetic analysis systems business, we face, and will continue to face, competition primarily from pharmaceutical, biotechnology and agricultural companies, as well as academic research institutions, clinical reference laboratories and government agencies. Some of our competitors, such as Affymetrix, Inc., Celera Genomics Group, Gene Logic, Inc., and Genome Therapeutics Corporation may be:

A number of large companies offer DNA sequencing equipment including Applera Corporation, Beckman Coulter, Inc., and the Amersham Biosciences business of General Electric. A number of other smaller companies are also in the process of developing novel techniques for DNA sequencing. These companies include 454 Corporation, Helicos Biosciences, Nanofluidics, Visigen and Genovoxx. In order to successfully compete against existing and future technologies, we will need to

5


demonstrate to potential customers that our technologies and capabilities are superior to those of our competitors. Some of our competitors may be:
• attempting to identify and patent randomly sequenced genes and gene fragments and proteins;
• pursuing a gene identification, characterization and product development strategy based on positional cloning, which uses disease inheritance patterns to isolate the genes that are linked to the transmission of disease from one generation to the next; and
• using a variety of different gene and protein expression analysis methodologies, including the use of chip-based systems, to attempt to identify disease-related genes and proteins.
      In addition, numerous pharmaceutical, biotechnology and agricultural companies are developing genomics research programs, either alone or in partnership with our competitors. Our future success will depend on our ability to maintain a competitive position with respect to technological advances. Rapid technological development by others may make our technologies and future products obsolete.

      Any products developed through our technologies will compete in highly competitive markets. Our competitors may be more effective at using their technologies to develop commercial products. Moreover, our competitors may introduce novel genetic analysis platforms before we do so, which, if adopted by customers, could eliminate the market for our new genetic analysis systems. Further, our competitors may obtain intellectual property rights that would limit the use of our technologies or the commercialization of diagnostic or therapeutic products using our technologies. As a result, our competitors’ products or technologies may render our technologies and products, and those of our collaborators, obsolete or noncompetitive.

If

We have limited experience in sales and marketing and thus may be unable to further commercialize our genetic analytical instruments systems and services.
      Our ability to achieve profitability depends on attracting customers for our genetic analysis instrument systems and services. There are a limited number of research institutes and pharmaceutical, biotechnology and agricultural companies that are potential customers for our products and services. To market our products, we failintend to adequately protect our proprietary technologies,develop a sales and marketing group with the appropriate technical expertise. We may not successfully build such a sales force. In addition, we may seek to enlist a third parties mayparty to assist with sales and distribution globally or in certain regions of the world. There is no guarantee, if we do seek to enter into such an arrangement, that we will be successful in attracting a desirable sales and distribution partner, or that we will be able to useenter into such an arrangement on favorable terms. If our sales and marketing efforts, or those of any third-party sales and distribution partner, are not successful, our technologies which could prevent us from competingand products may not to gain market acceptance.
Our sales cycle for our service business is lengthy, and we may spend considerable resources on unsuccessful sales efforts or may not be able to enter into agreements on the schedule we anticipate.
      Our ability to obtain customers and collaborators for our technologies and products depends in significant part upon the perception that our technologies and products can help accelerate their drug discovery and genomics efforts. Our sales cycle for our service business is typically lengthy, up to approximately nine months, because we need to educate our potential customers and collaborators and sell the benefits of our products to a variety of constituencies within such companies. In addition, we may be required to negotiate agreements containing terms unique to each collaborator or customer. We may expend substantial funds and management effort without any assurance that we will successfully sell our technologies and products. Actual and proposed consolidations of pharmaceutical companies have negatively affected, and may in the market.future negatively affect, the timing and progress of our sales efforts.
We currently utilize a single supplier to purchase PacI, an enzyme used in our MPSS service.
      PacI is a restriction enzyme used to digest the PCR product that is loaded onto 5-micron beads prior to MPSS sequencing. We currently purchase PacI from New England BioLabs under a supply agreement,

6


the term of which is scheduled to expire on August 15, 2005. Our reliance on a sole vendor involves several risks, including:
• the inability to obtain an adequate supply due to manufacturing capacity constraints, a discontinuance of a product by a third-party manufacturer or other supply constraints;
• the potential lack of leverage in contract negotiations with the sole vendor;
• reduced control over quality and pricing of components; and
• delays and long lead times in receiving materials from vendors.
      We do not believe, however, that our business is dependent substantially on PacI or the intellectual property associated with PacI. We believe that we would be able to purchase alternative enzymes from other providers without incurring significant additional expenses or time delays should the need arise. In addition, if we are able to successfully implement new SBS sequencing technologies under development in our genetic services business, we will no longer require PacI or an alternative enzyme. We intend to seek to extend or renew our contract with New England BioLabs and believe we can extend or renew the contract without unreasonable effort or expense.
We use hazardous chemicals and radioactive and biological materials in our business. Any claims relating to improper handling, storage or disposal of these materials could be time consuming and costly.
      Our research and development processes involve the controlled use of hazardous materials, including chemicals and radioactive and biological materials. Our operations produce hazardous waste products. We cannot eliminate the risk of accidental contamination or discharge and any resultant injury from these materials. We may be sued for any injury or contamination that results from our use or the use by third parties of these materials, and our liability may exceed our insurance coverage and our total assets. Federal, state and local laws and regulations govern the use, manufacture, storage, handling and disposal of hazardous materials. Compliance with environmental laws and regulations may be expensive, and current or future environmental regulations may impair our research, development and production efforts.
If we fail to adequately protect our proprietary technologies, third parties may be able to use our technologies, which could prevent us from competing in the market.
      Our success depends in part on our ability to obtain patents and maintain adequate protection of the intellectual property related to our technologies and products. The patent positions of biotechnology DNA sequencing instrument, regent sales and services companies, including our patent position,us, are generally uncertain and involve complex legal and factual questions. We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our proprietary technologies are covered by valid and enforceable patents or are effectively maintained as trade secrets. The laws of some foreign countries do not protect proprietary rights to the same extent as the laws of the U.S., and many companies have encountered significant problems in protecting and defending their proprietary rights in foreign jurisdictions. We have applied and will continue to apply for patents covering our technologies, processes and products, as and when we deem appropriate. However, third parties may challenge these applications, or these applications may fail to result in issued patents. Our existing patents and any future patents we obtain may not be sufficiently broad to prevent others from practicing our technologies or from developing competing products. Furthermore, others may independently develop similar or alternative technologies or design around our patents. In addition, our patents may be challenged or invalidated or fail to provide us with any competitive advantage.

      We also rely on trade secret protection for our confidential and proprietary information. However, trade secrets are difficult to protect. We protect our proprietary information and processes, in part, with confidentiality agreements with employees, collaborators and consultants. However, third parties may breach these agreements, we may not have adequate remedies for any such breach or our trade secrets may still otherwise become known by our competitors. In addition, our competitors may independently develop substantially equivalent proprietary information.

Litigation or third-party claims of intellectual property infringement could require us to spend substantial time and money and adversely affect our ability to develop and commercialize our technologies and products.7


Litigation or third-party claims of intellectual property infringement could require us to spend substantial time and money and adversely affect our ability to develop and commercialize our technologies and products.
      Our commercial success depends in part on our ability to avoid infringing patents and proprietary rights of third parties and not breaching any licenses that we have entered into with regard to our technologies. Other parties have filed, and in the future are likely to file, patent applications covering imaging, image analysis, fluid delivery, DNA arrays on solid surfaces, chemical and biological reagents for DNA sequencing, genes, gene fragments, proteins, the analysis of gene sequence, gene expression and protein expression and the manufacture and use of DNA chips or microarrays, which are tiny glass or silicon wafers on which tens of thousands of DNA molecules can be arrayed on the surface for subsequent analysis. We intend to continue to apply for patent protection for methods relating to gene expression and protein expression and for the individual disease genes and proteins and drug discovery targets we discover. If patents covering technologies required by our operations are issued to others, we may have to rely on licenses from third parties, which may not be available on commercially reasonable terms, or at all.

      Third parties may accuse us of employing their proprietary technology without authorization. In addition, third parties may obtain patents that relate to our technologies and claim that use of such technologies infringes these patents. Regardless of their merit, such claims could require us to incur substantial costs, including the diversion of management and technical personnel, in defending ourselves against any such claims or enforcing our patents. In the event that a successful claim of infringement is brought against us, we may need to pay damages and obtain one or more licenses from third parties. We may not be able to obtain these licenses at a reasonable cost, or at all. Defense of any lawsuit or failure to

4


obtain any of these licenses could adversely affect our ability to develop and commercialize our technologies and products and thus prevent us from achieving profitability.

We have limited experience in sales and marketing and thus may be unable to further commercialize our technologies and products.

     Our ability to achieve profitability depends on attracting collaborators and customers for our technologies and products. There are a limited number of pharmaceutical, biotechnology and agricultural companies and research institutes that are potential collaborators and customers for our technologies and products. To market our technologies and products, we must develop a sales and marketing group with the appropriate technical expertise. We may not successfully build such a sales force. If our sales and marketing efforts fail to be successful, our technologies and products may fail to gain market acceptance.

Our sales cycle is lengthy, and we may spend considerable resources on unsuccessful sales efforts or may not be able to enter into agreements on the schedule we anticipate.

     Our ability to obtain collaborators and customers for our technologies and products depends in significant part upon the perception that our technologies and products can help accelerate their drug discovery and genomics efforts. Our sales cycle is typically lengthy because we need to educate our potential collaborators and customers and sell the benefits of our products to a variety of constituencies within such companies. In addition, we may be required to negotiate agreements containing terms unique to each collaborator or customer. We may expend substantial funds and management effort without any assurance that we will successfully sell our technologies and products. Actual and proposed consolidations of pharmaceutical companies have negatively affected, and may in the future negatively affect, the timing and progress of our sales efforts.

The loss of key personnel or the inability to attract and retain additional personnel could impair the growth of our business.

     We are highly dependent on the principal members of our management and scientific staff. The loss of any of these persons’ services might adversely impact the achievement of our objectives and the continuation of existing customer, collaborative and license agreements. In addition, recruiting and retaining qualified scientific personnel to perform future research and development work will be critical to our success. There is currently a shortage of skilled executives and employees with technical expertise, and this shortage is likely to continue. As a result, competition for skilled personnel is intense and turnover rates are high. Competition for experienced scientists from numerous companies, academic and other research institutions may limit our ability to attract and retain such personnel. We depend on our President and Chief Executive Officer, Kevin P. Corcoran, the loss of whose services could have a material adverse effect on our business. Although we have an employment agreement with Mr. Corcoran in place, currently we do not maintain “key person” insurance for him or any other key personnel.

We use hazardous chemicals and radioactive and biological materials in our business. Any claims relating to improper handling, storage or disposal of these materials could be time consuming and costly.

     Our research and development processes involve the controlled use of hazardous materials, including chemicals and radioactive and biological materials. Our operations produce hazardous waste products. We cannot eliminate the risk of accidental contamination or discharge and any resultant injury from these materials. We may be sued for any injury or contamination that results from our use or the use by third parties of these materials, and our liability may exceed our insurance coverage and our total assets. Federal, state and local laws and regulations govern the use, manufacture, storage, handling and disposal of hazardous materials. Compliance with environmental laws and regulations may be expensive, and current or future environmental regulations may impair our research, development and production efforts.

Ethical, legal and social issues may limit the public acceptance of, and demand for, our technologies and products.

Ethical, legal and social issues may limit the public acceptance of, and demand for, our technologies and products.
      Our collaborators and customers may seek to develop diagnostic products based on genes or proteins. The prospect of broadly available gene-based diagnostic tests raises ethical, legal and social issues regarding the appropriate use of gene-based diagnostic testing and the resulting confidential information. It is possible that discrimination by third-party payors, based on the results of such testing, could lead to the increase of premiums by such payors to prohibitive levels, outright cancellation of insurance or unwillingness to provide coverage to individuals showing unfavorable gene or protein expression profiles. Similarly, employers could discriminate against employees with gene or protein expression profiles

5


indicative of the potential for high disease-related costs and lost employment time. Finally, government authorities could, for social or other purposes, limit or prohibit the use of such tests under certain circumstances. These ethical, legal and social concerns about genetic testing and target identification may delay or prevent market acceptance of our technologies and products.

      Although our technology does not depend on genetic engineering, genetic engineering plays a prominent role in our approach to product development. The subject of genetically modified food has received negative publicity, which has aroused public debate. Adverse publicity has resulted in greater regulation internationally and trade restrictions on imports of genetically altered agricultural products. Claims that genetically engineered products are unsafe for consumption or pose a danger to the environment may influence public attitudes and prevent genetically engineered products from gaining public acceptance. The commercial success of our future products may depend, in part, on public acceptance of the use of genetically engineered products, including drugs and plant and animal products.

If we develop products with our collaborators, and if product liability lawsuits are successfully brought against us, we could face substantial liabilities that exceed our resources.

     We may be held liable, if any product we develop with our collaborators causes injury or is otherwise found unsuitable during product testing, manufacturing, marketing or sale. Although we have general liability and product liability insurance, this insurance may become prohibitively expensive or may not fully cover our potential liabilities. Inability to obtain sufficient insurance coverage at an acceptable cost or to otherwise protect us against potential product liability claims could prevent or inhibit our ability to commercialize products developed with our collaborators.

Healthcare reform and restrictions on reimbursements may limit our returns on diagnostic or therapeutic products that we may develop with our collaborators.

     If we successfully validate targets for drug discovery, products that we develop with our collaborators based on those targets may include diagnostic or therapeutic products. The ability of our collaborators to commercialize such products may depend, in part, on the extent to which reimbursement for the cost of these products will be available from government health administration authorities, private health insurers and other organizations. In the U.S., third-party payors are increasingly challenging the price of medical products and services. The trend towards managed healthcare in the U.S., legislative healthcare reforms and the growth of organizations such as health maintenance organizations that may control or significantly influence the purchase of healthcare products and services, may result in lower prices for any products our collaborators may develop. Significant uncertainty exists as to the reimbursement status of newly approved healthcare products. If adequate third-party coverage is not available in the future, our collaborators may fail to maintain price levels sufficient to realize an appropriate return on their investment in research and product development.

Our facilities in Hayward, California are located near known earthquake fault zones, and the occurrence of an earthquake or other catastrophic disaster could cause damage to our facilities and equipment, which could require us to cease or curtail operations.
Our facilities are located near known earthquake fault zones, and the occurrence of an earthquake or other catastrophic disaster could cause damage to our facilities and equipment, which could require us to cease or curtail operations.

     Our facilitiesin Hayward, California are located near known earthquake fault zones and are vulnerable to damage from earthquakes. We are also vulnerable to damage from other types of disasters, including fire, floods, power loss, communications failures and similar events. If any disaster were to occur,

our ability to operate our business at our facilities would be seriously, or potentially completely, impaired. In addition, the unique nature of our research activities could cause significant delays in our programs and make it difficult for us to recover from a disaster. The insurance we maintain may not be adequate to cover our losses resulting from disasters or other business interruptions. Accordingly, an earthquake or other disaster could materially and adversely harm our ability to conduct business.

Our stock price may be extremely volatile.

Our stock price may be extremely volatile.
      We believe that the market price of our common stock will remain highly volatile and may fluctuate significantly due to a number of factors. The market prices for securities of many publicly-held, early-stage biotechnology companies have in the past been, and can in the future be expected to be, especially volatile. For example, during the two-year period from JanuaryApril 1, 20022004 to December 31, 2003,June 30, 2005, the closing sales price of our common stock as quoted on the Nasdaq National Market and Nasdaq SmallCap Market fluctuated from a low of $1.61$2.96 to a high of $32.89$17.00 per share. In addition, the securities markets have from time to time experienced significant price and volume fluctuations that may be unrelated to the operating performance of particular companies. The following factors and events may have a significant and adverse impact on the market price of our common stock:

6


• fluctuations in our operating results;
• announcements of technological innovations or new commercial products by us or our competitors;
• release of reports by securities analysts;
• developments or disputes concerning patent or proprietary rights;
• developments in our relationships with current or future collaborators, customers or licensees; and
• general market conditions.

announcements of technological innovations or new commercial products by us or our competitors;

release of reports by securities analysts;

developments or disputes concerning patent or proprietary rights;

developments in our relationships with current or future collaborators, customers or licensees; and

general market conditions.

      Many of these factors are beyond our control. These factors may cause a decrease in the market price of our common stock, regardless of our operating performance.

Our securities have been transferred from the Nasdaq National Market to the Nasdaq SmallCap Market, which has subjected us to various statutory requirements and may have adversely affected the liquidity of our common stock, and a failure by us to meet the listing maintenance standards of the Nasdaq SmallCap Market could result in delisting from the Nasdaq SmallCap Market.

Our common stock is listed on the Nasdaq SmallCap Market, which subjects us to various statutory requirements and may have adversely affected the liquidity of our common stock, and a failure by us to meet the listing maintenance standards of the Nasdaq SmallCap Market could result in delisting from the Nasdaq SmallCap Market.
      Effective May 22, 2003, a Nasdaq Qualifications Panel terminated our Nasdaq National Market Listing and transferred our securities to the Nasdaq SmallCap Market. In order to maintain the listing of our securities on the Nasdaq SmallCap Market, we must be able to demonstrate compliance with all applicable listing maintenance requirements. In the event we are unable to do so, our securities will be delisted from the Nasdaq Stock Market.

      With our securities listed on the Nasdaq SmallCap Market, we face a variety of legal and other consequences that will likely negatively affect our business including, without limitation, the following:
• we may have lost our exemption from the provisions of Section 2115 of the California Corporations Code, which imposes aspects of California corporate law on certain non-California corporations operating within California. As a result, (i) our stockholders may be entitled to cumulative voting and (ii) we may be subject to more stringent stockholder approval requirements and more stockholder-favorable dissenters’ rights in connection with certain strategic transactions;
• the state securities law exemptions available to us are more limited, and, as a result, future issuances of our securities may require time-consuming and costly registration statements and qualifications;

      In addition, we are required to satisfy various listing maintenance standards for our common stock to be quoted on the Nasdaq SmallCap Market. If we fail to meet such standards, our common stock would likely be delisted from the Nasdaq SmallCap Market and trade on the over-the-counter bulletin board, commonly referred to as the “pink sheets.”board. This alternative is generally considered to be a less efficient market and would seriously impair the liquidity of our common stock and limit our potential to raise future capital through the sale of our common stock, which could materially harm our business.

Anti-takeover provisions in our charter documents and under Delaware law may make it more difficult to acquire us or to effect a change in our management, even though an acquisition or management change may be beneficial to our stockholders.
      Under our certificate of incorporation, our board of directors has the authority, without further action by the holders of our common stock, to issue 2,000,000 additional shares of preferred stock from time to time in series and with preferences and rights as it may designate. These preferences and rights may be superior to those of the holders of our common stock. For example, the holders of preferred stock may be given a preference in payment upon our liquidation or for the payment or accumulation of dividends before any distributions are made to the holders of common stock.

7


      Any authorization or issuance of preferred stock, while providing desirable flexibility in connection with financings, possible acquisitions and other corporate purposes, could also have the effect of making it more difficult for a third party to acquire a majority of our outstanding voting stock or making it more difficult to remove directors and effect a change in management. The preferred stock may have other rights, including economic rights senior to those of our common stock, and, as a result, an issuance of additional preferred stock could lower the market value of our common stock. Provisions of Delaware law may also discourage, delay or prevent someone from acquiring or merging with us.

PLAN OF DISTRIBUTION
      The selling stockholders may, from time to time, sell any or all of their shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. The selling stockholders may use any one or more of the following methods when selling shares:
• ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
• block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;
• purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
• an exchange distribution in accordance with the rules of the applicable exchange;
• privately negotiated transactions;
• short sales;
• broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;
• a combination of any such methods of sale; and
• any other method permitted pursuant to applicable law.
      The selling stockholders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus.
      The selling stockholders may also engage in short sales against the box, puts and calls and other transactions in our securities or derivatives of our securities and may sell or deliver shares in connection with these trades.
      Broker-dealers engaged by the selling stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The selling stockholders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved. Any profits on the resale of shares of common stock by a broker-dealer acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. Discounts, concessions, commissions and similar selling expenses, if any, attributable to the sale of shares will be borne by a selling stockholder. The selling stockholders may agree to indemnify any agent, dealer or broker-dealer that participates in transactions involving sales of the shares if liabilities are imposed on that person under the Securities Act.

16


      The selling stockholders may from time to time pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time to time under this prospectus after we have filed an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933 amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus.
      The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.
      The selling stockholders and any broker-dealers or agents that are involved in selling the shares of common stock may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares of common stock purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.
      We are required to pay all fees and expenses incident to the registration of the shares. We have agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.
      The selling stockholders have advised us that they have not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of their shares of common stock, nor is there an underwriter or coordinating broker acting in connection with a proposed sale of shares of common stock by any selling stockholder. If we are notified by any selling stockholder that any material arrangement has been entered into with a broker-dealer for the sale of shares of common stock, if required, we will file a supplement to this prospectus. If the selling stockholders use this prospectus for any sale of the shares of common stock, they will be subject to the prospectus delivery requirements of the Securities Act.
      The anti-manipulation rules of Regulation M under the Securities Exchange Act of 1934 may apply to sales of our common stock and activities of the selling stockholders.

SELLING STOCKHOLDERS

         We issued 788,235 shares of our common stock, and warrants to purchase up to 181,295 shares of our common stock, in a private placement transaction on March 9, 2004. We are registering the 969,530 shares covered by this prospectus on behalf of the selling stockholders named in the table below. We agreed to register all of the above referenced shares of common stock for resale in connection with the terms and conditions of the March 9, 2004 private placement transaction. We have registered the shares to permit each of the selling stockholders and their pledgees, donees, transferees or other successors-in-interest that receive their shares from each selling stockholder as a gift, partnership distribution or other non-sale related transfer after the date of this prospectus to resell the shares.

         The following table sets forth the name of each selling stockholder, the number of shares owned by each of the respective selling stockholders, the number of shares that may be offered under this prospectus and the number of shares of our common stock owned by the selling stockholders after this offering is completed. Except as otherwise disclosed below, none of the selling stockholders has, or within the past three years has had, any position, office or other material relationship with us. The number of shares in the column “Number of Shares Being Offered” represents all of the shares that a selling stockholder may offer under this prospectus, and assumes the exercise of all the warrants for common stock. The selling stockholders may sell some, all or none of their shares. We do not know how long the selling stockholders will hold the shares before selling them, and we currently have no agreements, arrangements or understandings with the selling stockholders regarding the sale of any of the shares. The shares offered by this prospectus may be offered from time to time by the selling stockholders.

Beneficial ownership is determined in accordance with Rule 13d-3(d) promulgated by the SEC under the Securities Exchange Act of 1934. Unless otherwise noted, none of the share amounts set forth below represents more than 1% of our outstanding stock as of March 16, 2004, adjusted as required by rules promulgated by the SEC.

PLAN OF DISTRIBUTION

              The selling stockholders may, from time to time, sell any or all of their shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. The selling stockholders may use any one or more of the following methods when selling shares:

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;
purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
an exchange distribution in accordance with the rules of the applicable exchange;
privately negotiated transactions;
short sales;
broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;
a combination of any such methods of sale; and
any other method permitted pursuant to applicable law.

              The selling stockholders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus.

              The selling stockholders may also engage in short sales against the box, puts and calls and other transactions in our securities or derivatives of our securities and may sell or deliver shares in connection with these trades.

              Broker-dealers engaged by the selling stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The selling stockholders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved. Any profits on the resale of shares of common stock by a broker-dealer acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. Discounts, concessions, commissions and similar selling expenses, if any, attributable to the sale of shares will be borne by a selling stockholder. The selling stockholders may agree to indemnify any agent, dealer or broker-dealer that participates in transactions involving sales of the shares if liabilities are imposed on that person under the Securities Act.

              The selling stockholders may from time to time pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time to time under this prospectus after we have filed an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933 amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus.

              The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus and may sell the shares of common stock from time to time under this prospectus after we have filed an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933 amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus.

11


              The selling stockholders and any broker-dealers or agents that are involved in selling the shares of common stock may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares of common stock purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.

              We are required to pay all fees and expenses incident to the registration of the shares of common stock, including $10,000 of fees and disbursements of counsel to the selling stockholders. We have agreed to indemnify the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

              The selling stockholders have advised us that they have not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of their shares of common stock, nor is there an underwriter or coordinating broker acting in connection with a proposed sale of shares of common stock by any selling stockholder. If we are notified by any selling stockholder that any material arrangement has been entered into with a broker-dealer for the sale of shares of common stock, if required, we will file a supplement to this prospectus. If the selling stockholders use this prospectus for any sale of the shares of common stock, they will be subject to the prospectus delivery requirements of the Securities Act.

              The anti-manipulation rules of Regulation M under the Securities Exchange Act of 1934 may apply to sales of our common stock and activities of the selling stockholders.

              The validity of the shares of common stock offered hereby will be passed upon by Cooley Godward LLP, Palo Alto, California. James C. Kitch, a partner at Cooley Godward LLP, has served as a director of Lynx since 1993, and owns 2,568 shares of our common stock, a warrant to purchase 908 shares of our common stock and options to purchase 4,210 shares of our common stock.

Item 15.Indemnification of Officers and Directors

Item 15. Indemnification of Directors and Officers

      As permitted by Delaware law, our amended and restated certificate of incorporation provides that no director of ours will be personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director, except for liability:

for any breach of duty of loyalty to us or to our stockholders;

• for any breach of duty of loyalty to us or to our stockholders;
• for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;
• for unlawful payment of dividends or unlawful stock repurchases or redemptions under Section 174 of the Delaware General Corporation Law; or
• for any transaction from which the director derived an improper personal benefit.

for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;

for unlawful payment of dividends or unlawful stock repurchases or redemptions under Section 174 of the Delaware General Corporation Law; or

for any transaction from which the director derived an improper personal benefit.

      Our bylaws, as amended, further provides that we must indemnify our directors and executive officers and may indemnify our other officers and employees and agents to the fullest extent permitted by Delaware law. We believe that indemnification under our bylaws, as amended, covers negligence and gross negligence on the part of indemnified parties.

      We have entered into indemnification agreements with each of our directors and certain officers. These agreements, among other things, require us to indemnify each director and officer for certain expenses including attorneys’ fees, judgments, fines and settlement amounts incurred by any such person in any action or proceeding, including any action by or in the right of Lynx Therapeutics,Solexa, Inc., arising out of the person’s services as our director or officer, any subsidiary of ours or any other company or enterprise to which the person provides services at our request.

      At present, there is no pending litigation or proceeding involving a director or officer of LynxSolexa as to which indemnification is being sought nor are we aware of any threatened litigation that may result in claims for indemnification by any officer or director.

(i) To include any prospectus required by section 10(a)(3) of the Securities Act;

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) (§ 230.424(b) of this chapter) 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 to thatsuch information in the registration statement.statement;

Provided, however, that paragraphs (a)(i) and (a)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the issuer pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference herein.

2. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
