About F-star Therapeutics, Inc.

We are a clinical-stage biopharmaceutical company dedicated to developing next generation immunotherapies to transform the lives of patients with cancer. Our goal is to offer patients better and more durable benefits than currently available immuno-oncology treatments by developing medicines that seek to block tumor immune evasion. Through our proprietary tetravalent, bispecific natural antibody (mAb²) format, our mission is to generate highly differentiated medicines with monoclonal antibody-like manufacturability, good safety and tolerability. With four distinct binding sites in a natural human antibody format, we believe our proprietary technology will overcome many of the challenges facing current immuno-oncology therapies, due to the strong pharmacology enabled by tetravalent bispecific binding.

In 2020, combined sales of current immuno-oncology therapies were estimated to be approximately $28.7 billion. Despite the commercial success of currently approved immuno-oncology products, only approximately 20% of patients realize a long-lasting benefit from these treatments, leaving a large, unserved patient population without effective treatment options.

We believe the novel tetravalent and natural human antibody formats of our mAb2 bispecific antibodies have the potential to focus immune activation to enhance efficacy and reduce systemic toxicities.

Our mission is to generate highly differentiated, first and/or best-in-class product candidates that will transform the lives of patients with cancer. The key elements of our strategy include:

 

   

Rapidly accelerating the clinical development of our three novel mAb2 product candidates and novel cyclic dinucleotide, SB 11285, to treat a range of advanced cancers. We believe our mAb2 product candidates represent potentially best-in-class immuno-oncology therapies that address a variety of patients with cancer inadequately treated with existing therapies. We believe FS118, which is being evaluated in a proof of concept trial in PD-1/PD-L1 acquired resistance head and neck cancer patients, has the potential to provide significant clinical benefit through its dual-checkpoint inhibitor targets (LAG-3 and PD-L1). In addition to FS118, we are currently evaluating FS120, FS222 and SB 11285 for safety, tolerability and efficacy in Phase 1 clinical trials in patients with advanced cancers with the potential to address multiple immune evasion pathways that limit the effect of current immuno-oncology therapies.

 

   

Initially focusing our development strategy on tumors where checkpoint inhibitors are currently utilized but are poor long-term treatment options, and then subsequently broadening to other tumor types and potentially, first-line therapies. Our early-stage clinical trials include or will include a broad range of tumor types to evaluate safety, tolerability and dosing, as well as early signals of efficacy. Following these early-stage

clinical trials, we intend to employ a patient selection strategy, using biomarkers to focus further development on targeted patient subsets. These subsets are expected to include patients with high cancer target co-expression and/or resistance to current checkpoint therapies. We believe our mAb2 bispecific antibodies and SB 11285 may also ultimately deliver therapeutic benefit in a broader range of tumors, expanding beyond the initial indications we may pursue. We believe our development strategy best serves the patient, can be efficiently pursued by our organization and, is likely to lead to a rapid development strategy and regulatory pathway to market. For example, we have identified several tumor types which have a strong fit with the potential FS118 mechanism of action, including appropriate target expression, that would be candidates for accelerated approval pathways.

 

   

Leveraging the transformational potential of our modular antibody technology platform to create a leading immuno-oncology pipeline of differentiated clinical assets capable of improving patient outcomes. Our proprietary mAb2 bispecific antibodies have a number of potential advantages, compared to other modalities, resulting from their novel tetravalent and natural human antibody formats, which we believe will result in improved efficacy, minimized toxicity and simplified manufacturability. We believe our technology has the potential to be matched with any antibody domain in a modular “plug-and-play” approach to further expand our innovative pipeline of mAb2 product candidates. We believe these benefits provide multiple opportunities to consistently generate clinical candidates that could potentially address the needs of patients who are without adequate therapeutic options.

 

   

Leveraging and continuing to build our extensive intellectual property portfolio in order to protect our dominant position in mAb2 bispecific antibodies and our STING agonist program. We have built an extensive patent portfolio around our mAb2 technology and product pipeline. In addition, we have STING pathway-related filings, including those of a patent family relating to the composition of matter of the STING agonist SB 11285. This patent estate relates to our mAb2 bispecific format and STING agonist program and aims to provide us with robust intellectual property exclusivity and prohibit use of our technology by third parties. We intend to continue to seek additional patent protection as we develop additional novel mAb2 product candidates.

We have collaborative partnerships with Ares Trading S.A., an affiliate of Merck KGaA, Darmstadt, Germany, Denali Therapeutics Inc. and Kymab Limited, which enable us to further validate our technological approach. To date, we have generated more than $165.0 million in revenue from all collaborations. We believe that these partnerships will provide both continued validation and ongoing revenue as we continue to advance our proprietary pipeline.

We are led by a team of highly experienced executives, clinicians, scientists and advisors with notable expertise in antibody research, immuno-oncology, antibody manufacturing and clinical development. Our team has spent over a decade developing our proprietary mAb2 technology into a robust drug discovery platform. Our team has collectively worked on the development of 20 marketed products and has worked at companies including AstraZeneca, BMS, Celgene Corporation, Domantis Ltd., Eli Lilly, GSK, Immunocore Ltd. and Pfizer Inc.

Our Pipeline

FS118

Our most advanced product candidate, FS118, is currently being evaluated in a proof-of-concept trial in PD-1/PD-L1 acquired resistance head and neck cancer patients. FS118 is a tetravalent mAb2 bispecific antibody

Table of Contents

targeting two receptors, PD-L1 and LAG-3, both of which are established pivotal targets in immuno-oncology. Phase 1 data from 43 heavily pre-treated patients with advanced cancer, who have failed PD-1/PD-L1 therapy, showed that administration of FS118 was well-tolerated with no dose limiting toxicities up to 20/mg/kg. In addition, a disease control rate (“DCR”), defined as either a complete response, partial response or stable disease, of 49% was observed in 39 evaluable patients receiving dose levels of FS118 at 1 mg/kg or greater. In acquired resistance patients, DCR was 59% (16 out of 27 patients) and long-term (greater than six months) disease control was observed in six of these patients. We expect to provide an update from the proof-of-concept trial in PD-1/PD-L1 acquired resistance head and neck cancer patients in H1 2022.

FS120

We initiated a Phase 1 clinical trial for FS120 in patients with advanced cancers in late 2020. FS120 is a first-in-class dual agonist bispecific antibody, an antibody that stimulates two immune activating pathways, which we believe has the potential to overcome cancer resistance by simultaneously targeting CD137 (4-1BB) and OX40, two receptors present on the surface of tumor-infiltrating lymphocytes. Unlike checkpoint inhibitors, the mechanism of action of FS120 is designed to trigger a positive signal that enhances multiple mechanisms essential for killing tumor cells. FS120 has a natural human antibody format. It is engineered to abrogate Fc gamma receptor binding and effector activity, providing increased specificity and, we believe, superior performance while reducing toxicity through engineered conditional, crosslink-dependent activation upon binding to both CD137 and OX40. We expect to enroll up to 70 patients in a Phase 1 dose escalation clinical trial to assess the safety, tolerability and efficacy of FS120 in patients with advanced malignancies and include those patients who have high co-expression of CD137 and OX40. We expect to provide an update on study progress in mid-2021.

FS222

The third bispecific program from our proprietary platform, FS222, began a Phase 1 clinical trial for FS222 in patients with advanced cancers in late 2020. FS222 has the potential to provide clinical benefit through multiple mechanisms based on its tetravalency. These include: (1) blocking the PD-1/PD-L1 immunosuppressive pathway and (2) conditionally clustering and crosslinking CD137 receptors, resulting in activation of CD137 in a PD-L1-dependent manner. We believe this dual mechanism of action could lead to strong anti-tumor activity of FS222 including benefits in cancers with low PD-L1 expression. Our preclinical data shows that FS222 has the potential to be more effective than a combination of traditional PD-L1 and CD137 antibodies. FS222 has been designed with specific mutations to make its activity independent of binding to Fc gamma receptors. PD-L1 is frequently highly expressed on cells within cancer tissue compared to non-cancer tissue. Therefore, we believe this will make FS222 immune activation conditional within cancer tissue, limit potential systemic toxicities and lead to safety benefits. We expect to initiate a Phase 1 expansion cohort to measure pharmacokinetic (PK)/ pharmacodynamic (PD) for FS222 in Q4 2021.

SB 11285

In addition to the mAb2 product candidates, we are evaluating SB 11285 in a Phase 1 clinical trial as an intravenously (IV) administered monotherapy, and in combination with an anti-PD-L1 antibody, in patients with advanced cancers. SB 11285 is a next generation cyclic dinucleotide-based STING agonist with efficient cellular uptake. We believe that SB 11285 has the potential to produce anti-tumor activity by inducing interferon pathways and activating the innate and, indirectly, the adaptive immune system. We believe combining SB 11285 with PD-L1 therapy will further enhance anti-tumor activity. SB 11285 has been designed to allow IV administration which we believe will increase its applicability to treat a wide variety of advanced cancers. We expect to report an update on the trial in mid-2021.

Research

The tetravalent format of FS118 simultaneously targets two immune checkpoint receptors, LAG-3 and PD-L1, to directly address known tumor evasion pathways. FS118 is currently being evaluated in a proof-of-concept trial in PD-1/PD-L1 acquired resistance head and neck cancer patients. In the Phase 1 clinical trial in heavily pre-treated patients with advanced cancer who have failed PD-1/PD-L1 therapy it was demonstrated that administration of FS118 was well-tolerated and has provided long-term disease control in these patients. Our clinical pipeline also includes FS120, which targets CD137 and OX40 and FS222, which targets PD-L1 and CD137 and SB 11285 which targets the STING pathway. FS120 and FS222 are currently being evaluated for safety, tolerability and efficacy in Phase 1 clinical trials in patients with advanced cancers. SB 11285 is a next generation cyclic dinucleotide-based STING agonist that is being evaluated for safety, tolerability and efficacy as a monotherapy and in combination with an anti-PD-L1 antibody in a Phase 1 clinical trial with advanced cancers. Our portfolio includes further preclinical and clinical programs that are being developed by our partners.

Our Platform

We leverage our proprietary mAb2 technology to build our portfolio of wholly-owned immuno-oncology mAb2 product candidates and have generated a panel of early stage Fcab building blocks against a range of targets with the potential to go beyond immuno-oncology. These Fcab building blocks have been used to generate not only bispecific antibodies but also trispecific antibodies. We have over 230 granted patents and over 150 pending applications relating to our mAb2 technology and our product pipeline. We believe we have a leading position in mAb2 bispecific antibody development, and third parties are prohibited from utilizing our mAb2 technology without obtaining a license from us.

Impact of COVID-19

In March 2020, the World Health Organization declared the novel strain of coronavirus (COVID-19) a global pandemic and recommended containment and mitigation measures worldwide. The COVID-19 pandemic has been evolving, and to date has led to the implementation of various responses, including government-imposed quarantines, travel restrictions and other public health safety measures.

Management continues to closely monitor the impact of the COVID-19 pandemic on all aspects of the business, including how it will impact operations and the operations of customers, vendors, and business partners. Management took action in April 2020 to temporarily furlough some of its workforce which was reimbursed for $0.5 million by the Coronavirus Job Retention Scheme in the UK. Management did see approximately a three-to-six-month delay in the operationalization of its clinical trials for FS118, FS120, FS222 and SB 11285. The extent to which COVID-19 impacts the future business, results of operation and financial condition will depend on future developments, which are highly uncertain and cannot be predicted with confidence at this time, such as the continued duration of the outbreak, new information that may emerge concerning the severity or other strains of COVID-19 or the effectiveness of actions to contain COVID-19 or treat its impact, among others. If we or any of the third parties with which we engage, however, were to experience shutdowns or other business disruptions, the ability to conduct our business in the manner and on the timelines presently planned could be materially and negatively affected, which could have a material adverse impact on business, results of operation

USE OF PROCEEDS

Unless otherwise indicated in the applicable prospectus supplement, we intend to use any net proceeds from the sale of securities under this prospectus for general corporate purposes, including, but not limited to, clinical trials, research and development activities, working capital, capital expenditures, acquisitions, should we choose to pursue any, and collaborations. We have not determined the amounts we plan to spend on any of the areas listed above or the timing of these expenditures. As a result, our management will have broad discretion to allocate the net proceeds, if any, we receive in connection with securities offered pursuant to this prospectus for any purpose.

PLAN OF DISTRIBUTION

We may offer securities under this prospectus from time to time pursuant to underwritten public offerings, negotiated transactions, block trades or a combination of these methods. We may sell the securities (1) through underwriters or dealers, (2) through agents or (3) directly to one or more purchasers, or through a combination of such methods. We may distribute the securities from time to time in one or more transactions at:

 

   

a fixed price or prices, which may be changed from time to time;

 

   

market prices prevailing at the time of sale;

 

   

prices related to the prevailing market prices; or

 

   

negotiated prices.

We may directly solicit offers to purchase the securities being offered by this prospectus. We may also designate agents to solicit offers to purchase the securities from time to time and may enter into arrangements for “at-the-market,” equity line or similar transactions. We will name in a prospectus supplement any underwriter or agent involved in the offer or sale of the securities.

If we utilize a dealer in the sale of the securities being offered by this prospectus, we will sell the securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.

If we utilize an underwriter in the sale of the securities being offered by this prospectus, we will execute an underwriting agreement with the underwriter at the time of sale, and we will provide the name of any underwriter in the prospectus supplement which the underwriter will use to make resales of the securities to the public. In connection with the sale of the securities, we, or the purchasers of the securities for whom the underwriter may act as agent, may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the securities to or through dealers, and the underwriter may compensate those dealers in the form of discounts, concessions or commissions.

With respect to underwritten public offerings, negotiated transactions and block trades, we will provide in the applicable prospectus supplement information regarding any compensation we pay to underwriters, dealers or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers. Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters within the meaning of the Securities Act, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions. We may enter into agreements to indemnify underwriters, dealers and agents against civil liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make in respect thereof.

If so indicated in the applicable prospectus supplement, we will authorize underwriters, dealers or other persons acting as our agents to solicit offers by certain institutions to purchase securities from us pursuant to delayed delivery contracts providing for payment and delivery on the date stated in each applicable prospectus supplement. Each contract will be for an amount not less than, and the aggregate amount of securities sold pursuant to such contracts shall not be less nor more than, the respective amounts stated in each applicable prospectus supplement. Institutions with whom the contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions, but shall in all cases be subject to our approval. Delayed delivery contracts will not be subject to any conditions except that:

 

   

the purchase by an institution of the securities covered under that contract shall not at the time of delivery be prohibited under the laws of the jurisdiction to which that institution is subject; and

 

12


Table of Contents
   

if the securities are also being sold to underwriters acting as principals for their own account, the underwriters shall have purchased such securities not sold for delayed delivery. The underwriters and other persons acting as our agents will not have any responsibility in respect of the validity or performance of delayed delivery contracts.

One or more firms, referred to as “remarketing firms,” may also offer or sell the securities, if a prospectus supplement so indicates, in connection with a remarketing arrangement upon their purchase. Remarketing firms will act as principals for their own accounts or as our agents. These remarketing firms will offer or sell the securities in accordance with the terms of the securities. Each prospectus supplement will identify and describe any remarketing firm and the terms of its agreement, if any, with us and will describe the remarketing firm’s compensation. Remarketing firms may be deemed to be underwriters in connection with the securities they remarket. Remarketing firms may be entitled under agreements that may be entered into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, and may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

Certain underwriters may use this prospectus and any accompanying prospectus supplement for offers and sales related to market-making transactions in the securities. These underwriters may act as principal or agent in these transactions, and the sales will be made at prices related to prevailing market prices at the time of sale. Any underwriters involved in the sale of the securities may qualify as “underwriters” within the meaning of Section 2(a)(11) of the Securities Act. In addition, the underwriters’ commissions, discounts or concessions may qualify as underwriters’ compensation under the Securities Act and the rules of the Financial Industry Regulatory Authority, Inc., or FINRA.

Shares of our common stock sold pursuant to the registration statement of which this prospectus is a part will be authorized for listing and trading on the Nasdaq Capital Market. The applicable prospectus supplement will contain information, where applicable, as to any other listing, if any, on the Nasdaq Capital Market or any securities market or other securities exchange of the securities covered by the prospectus supplement. Underwriters may make a market in our common stock but will not be obligated to do so and may discontinue any market making at any time without notice. We can make no assurance as to the liquidity of or the existence, development or maintenance of trading markets for any of the securities.

In order to facilitate the offering of the securities, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the securities. This may include over-allotments or short sales of the securities, which involve the sale by persons participating in the offering of more securities than we sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option. In addition, these persons may stabilize or maintain the price of the securities by bidding for or purchasing the applicable security in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if the securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

The underwriters, dealers and agents may engage in other transactions with us, or perform other services for us, in the ordinary course of their business.

We are authorized to issue one class of common stock. Holders of our common stock are entitled to one vote for each share of common stock held of record for the election of directors and on all matters submitted to a vote of stockholders, except matters that relate only to one or more of the series of our preferred stock, and no holder has cumulative voting rights. Accordingly, the holders of a majority of the shares of common stock entitled to vote in any election of directors can elect all of the directors standing for election, if they so choose. Subject to preferences that may be applicable to any then outstanding preferred stock, holders of our common stock are entitled to receive dividends ratably, if any, as may be declared by our board of directors out of legally available funds, subject to any preferential dividend rights of any preferred stock then outstanding. Upon our dissolution, liquidation or winding up, holders of our common stock are entitled to share ratably in our net assets legally available after the payment of all our debts and other liabilities, subject to the preferential rights of any preferred stock then outstanding. Holders of our common stock have no preemptive, subscription, redemption or conversion rights. The rights, preferences and privileges of holders of common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that are currently designated and issued or that we may designate and issue in the future. Except as described under “Certain Provisions of Delaware Law and of the Company’s Certificate of Incorporation and Bylaws—Anti-Takeover Provisions” below, a majority vote of the holders of common stock is generally required to take action under our amended and restated certificate of incorporation and amended and restated bylaws.

DESCRIPTION OF PREFERRED STOCK

The following description of our preferred stock and the description of the terms of any particular series of preferred stock that we choose to issue hereunder are not complete. These descriptions are qualified in their entirety by reference to our amended and restated certificate of incorporation and the certificate of designation relating to any series of preferred stock issued by us. The rights, preferences, privileges and restrictions of the preferred stock of each series will be fixed by the certificate of designation relating to that series.

We are authorized, without action by the stockholders, to designate and issue up to an aggregate of 10,000,000 shares of preferred stock, par value $0.0001 per share. As of the date of this prospectus, no shares of our preferred stock were outstanding or designated. The following summary of certain provisions of our preferred stock does not purport to be complete. You should refer to our restated certificate of incorporation and our restated bylaws, both of which are included as exhibits to the registration statement of which this prospectus is a part. The summary below is also qualified by provisions of applicable law.

General

Our board of directors can designate the rights, preferences and privileges of the shares of each series and any of its qualifications, limitations or restrictions. Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of common stock. The issuance of preferred stock, while providing flexibility in connection with possible future financings and acquisitions and other corporate purposes could, under certain circumstances, have the effect of restricting dividends on our common stock, diluting the voting power of our common stock, impairing the liquidation rights of our common stock, or delaying, deferring or preventing a change in control of our Company, which might harm the market price of our common stock. See also “Certain Provisions of Delaware Law and of the Company’s Certificate of Incorporation and Bylaws—Anti-Takeover Provisions.” Our board of directors will make any determination to issue such shares based on its judgment as to our Company’s best interests and the best interests of our stockholders.

If we offer a specific series of preferred stock under this prospectus, we will describe the terms of the preferred stock in the prospectus supplement for such offering and will file a copy of the amended and restated certificate establishing the terms of the preferred stock with the SEC. To the extent required, this description will include:

 

   

the maximum number of shares;

 

   

the designation of the shares;

the voting rights;

DESCRIPTION OF DEBT SECURITIES

The following description, together with the additional information we include in any applicable prospectus supplements, summarizes the material terms and provisions of the debt securities that we may offer under this prospectus. While the terms we have summarized below will apply generally to any future debt securities we may offer pursuant to this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the applicable prospectus supplement. If we so indicate in a prospectus supplement, the terms of any debt securities offered under such prospectus supplement may differ from the terms we describe below, and to the extent the terms set forth in a prospectus supplement differ from the terms described below, the terms set forth in the prospectus supplement shall control.

We may sell from time to time, in one or more offerings under this prospectus, debt securities, which may be senior or subordinated. We will issue any such senior debt securities under a senior indenture that we will enter into with a trustee to be named in the senior indenture. We will issue any such subordinated debt securities under a subordinated indenture, which we will enter into with a trustee to be named in the subordinated indenture. We have filed forms of these documents as exhibits to the registration statement, of which this prospectus is a part. We use the term “indentures” to refer to either the senior indenture or the subordinated indenture, as applicable. The indentures will be qualified under the Trust Indenture Act of 1939, as in effect on the date of the indenture. We use the term “debenture trustee” to refer to either the trustee under the senior indenture or the trustee under the subordinated indenture, as applicable.

The following summaries of material provisions of the senior debt securities, the subordinated debt securities and the indentures are subject to, and qualified in their entirety by reference to, all the provisions of the indenture applicable to a particular series of debt securities.

General

Each indenture provides that debt securities may be issued from time to time in one or more series and may be denominated and payable in foreign currencies or units based on or relating to foreign currencies. Neither indenture limits the amount of debt securities that may be issued thereunder, and each indenture provides that the specific terms of any series of debt securities shall be set forth in, or determined pursuant to, an authorizing resolution and/or a supplemental indenture, if any, relating to such series.

We will describe in each prospectus supplement the following terms relating to a series of debt securities:

 

   

the title or designation;

 

   

the aggregate principal amount and any limit on the amount that may be issued;

 

   

the currency or units based on or relating to currencies in which debt securities of such series are denominated and the currency or units in which principal or interest or both will or may be payable;

 

   

whether we will issue the series of debt securities in global form, the terms of any global securities and who the depositary will be;

 

   

the maturity date and the date or dates on which principal will be payable;

 

   

the interest rate, which may be fixed or variable, or the method for determining the rate and the date interest will begin to accrue, the date or dates interest will be payable and the record dates for interest payment dates or the method for determining such dates;

 

   

whether or not the debt securities will be secured or unsecured, and the terms of any secured debt;

 

   

the terms of the subordination of any series of subordinated debt;

 

   

the place or places where payments will be payable;

 

   

our right, if any, to defer payment of interest and the maximum length of any such deferral period;

 

17


Table of Contents
   

the date, if any, after which, and the price at which, we may, at our option, redeem the series of debt securities pursuant to any optional redemption provisions;

 

   

the date, if any, on which, and the price at which we are obligated, pursuant to any mandatory sinking fund provisions or otherwise, to redeem, or at the holder’s option to purchase, the series of debt securities;

 

   

whether the indenture will restrict our ability to pay dividends, or will require us to maintain any asset ratios or reserves;

 

   

whether we will be restricted from incurring any additional indebtedness;

 

   

a discussion of any material or special U.S. federal income tax considerations applicable to a series of debt securities;

 

   

the denominations in which we will issue the series of debt securities, if other than denominations of $1,000 and any integral multiple thereof; and

 

   

any other specific terms, preferences, rights or limitations of, or restrictions on, the debt securities.

We may issue debt securities that provide for an amount less than their stated principal amount to be due and payable upon declaration of acceleration of their maturity pursuant to the terms of the indenture. We will provide you with information on the federal income tax considerations and other special considerations applicable to any of these debt securities in the applicable prospectus supplement.

Conversion or Exchange Rights

We will set forth in the prospectus supplement the terms, if any, on which a series of debt securities may be convertible into or exchangeable for our common stock or our other securities. We will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option. We may include provisions pursuant to which the number of shares of our common stock or our other securities that the holders of the series of debt securities receive would be subject to adjustment.

Consolidation, Merger or Sale; No Protection in Event of a Change of Control or Highly Leveraged Transaction

The indentures do not contain any covenant that restricts our ability to merge or consolidate, or sell, convey, transfer or otherwise dispose of all or substantially all of our assets. However, any successor to or acquirer of such assets must assume all of our obligations under the indentures or the debt securities, as appropriate.

Unless we state otherwise in the applicable prospectus supplement, the debt securities will not contain any provisions that may afford holders of the debt securities protection in the event we have a change of control or in the event of a highly leveraged transaction (whether or not such transaction results in a change of control), which could adversely affect holders of debt securities.

Events of Default Under the Indenture

The following are events of default under the indentures with respect to any series of debt securities that we may issue:

 

   

if we fail to pay interest when due and our failure continues for 90 days and the time for payment has not been extended or deferred;

 

   

if we fail to pay the principal, or premium, if any, when due and the time for payment has not been extended or delayed;

 

   

if we fail to observe or perform any other covenant set forth in the debt securities of such series or the applicable indentures, other than a covenant specifically relating to and for the benefit of holders of

 

18


Table of Contents
 

another series of debt securities, and our failure continues for 90 days after we receive written notice from the debenture trustee or holders of not less than a majority in aggregate principal amount of the outstanding debt securities of the applicable series; and

 

   

if specified events of bankruptcy, insolvency or reorganization occur as to us.

No event of default with respect to a particular series of debt securities (except as to certain events of bankruptcy, insolvency or reorganization) necessarily constitutes an event of default with respect to any other series of debt securities. The occurrence of an event of default may constitute an event of default under any bank credit agreements we may have in existence from time to time. In addition, the occurrence of certain events of default or an acceleration under the indenture may constitute an event of default under certain of our other indebtedness outstanding from time to time.

If an event of default with respect to debt securities of any series at the time outstanding occurs and is continuing, then the trustee or the holders of not less than a majority in principal amount of the outstanding debt securities of that series may, by a notice in writing to us (and to the debenture trustee if given by the holders), declare to be due and payable immediately the principal (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be specified in the terms of that series) of and premium and accrued and unpaid interest, if any, on all debt securities of that series. Before a judgment or decree for payment of the money due has been obtained with respect to debt securities of any series, the holders of a majority in principal amount of the outstanding debt securities of that series (or, at a meeting of holders of such series at which a quorum is present, the holders of a majority in principal amount of the debt securities of such series represented at such meeting) may rescind and annul the acceleration if all events of default, other than the non-payment of accelerated principal, premium, if any, and interest, if any, with respect to debt securities of that series, have been cured or waived as provided in the applicable indenture (including payments or deposits in respect of principal, premium or interest that had become due other than as a result of such acceleration). We refer you to the prospectus supplement relating to any series of debt securities that are discount securities for the particular provisions relating to acceleration of a portion of the principal amount of such discount securities upon the occurrence of an event of default.

Subject to the terms of the indentures, if an event of default under an indenture shall occur and be continuing, the debenture trustee will be under no obligation to exercise any of its rights or powers under such indenture at the request or direction of any of the holders of the applicable series of debt securities, unless such holders have offered the debenture trustee reasonable indemnity. The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the debenture trustee, or exercising any trust or power conferred on the debenture trustee, with respect to the debt securities of that series, provided that:

 

   

the direction so given by the holder is not in conflict with any law or the applicable indenture; and

 

   

subject to its duties under the Trust Indenture Act, the debenture trustee need not take any action that might involve it in personal liability or might be unduly prejudicial to the holders not involved in the proceeding.

A holder of the debt securities of any series will only have the right to institute a proceeding under the indentures or to appoint a receiver or trustee, or to seek other remedies if:

 

   

the holder previously has given written notice to the debenture trustee of a continuing event of default with respect to that series;

 

   

the holders of at least a majority in aggregate principal amount of the outstanding debt securities of that series have made written request, and such holders have offered reasonable indemnity to the debenture trustee to institute the proceeding as trustee; and

 

   

the debenture trustee does not institute the proceeding and does not receive from the holders of a majority in aggregate principal amount of the outstanding debt securities of that series (or at a meeting

 

19


Table of Contents
 

of holders of such series at which a quorum is present, the holders of a majority in principal amount of the debt securities of such series represented at such meeting) other conflicting directions within 60 days after the notice, request and offer.

These limitations do not apply to a suit instituted by a holder of debt securities if we default in the payment of the principal, premium, if any, or interest on, the debt securities.

We will periodically file statements with the applicable debenture trustee regarding our compliance with specified covenants in the applicable indenture.

Modification of Indenture; Waiver

The debenture trustee and we may change the applicable indenture without the consent of any holders with respect to specific matters, including:

 

   

to fix any ambiguity, defect or inconsistency in the indenture; and

 

   

to change anything that does not materially adversely affect the interests of any holder of debt securities of any series issued pursuant to such indenture.

In addition, under the indentures, the rights of holders of a series of debt securities may be changed by us and the debenture trustee with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each series (or, at a meeting of holders of such series at which a quorum is present, the holders of a majority in principal amount of the debt securities of such series represented at such meeting) that is affected. However, the debenture trustee and we may make the following changes only with the consent of each holder of any outstanding debt securities affected:

 

   

extending the fixed maturity of the series of debt securities;

 

   

reducing the principal amount, reducing the rate of or extending the time of payment of interest, or any premium payable upon the redemption of any debt securities;

 

   

reducing the principal amount of discount securities payable upon acceleration of maturity;

 

   

making the principal of or premium or interest on any debt security payable in currency other than that stated in the debt security; or

 

   

reducing the percentage of debt securities, the holders of which are required to consent to any amendment or waiver.

Except for certain specified provisions, the holders of at least a majority in principal amount of the outstanding debt securities of any series (or, at a meeting of holders of such series at which a quorum is present, the holders of a majority in principal amount of the debt securities of such series represented at such meeting) may on behalf of the holders of all debt securities of that series waive our compliance with provisions of the indenture. The holders of a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all the debt securities of such series waive any past default under the indenture with respect to that series and its consequences, except a default in the payment of the principal of, premium or any interest on any debt security of that series or in respect of a covenant or provision, which cannot be modified or amended without the consent of the holder of each outstanding debt security of the series affected; provided, however, that the holders of a majority in principal amount of the outstanding debt securities of any series may rescind an acceleration and its consequences, including any related payment default that resulted from the acceleration.

Discharge

Each indenture provides that we can elect to be discharged from our obligations with respect to one or more series of debt securities, except for obligations to:

 

   

register the transfer or exchange of debt securities of the series;

 

20


Table of Contents
   

replace stolen, lost or mutilated debt securities of the series;

 

   

maintain paying agencies;

 

   

hold monies for payment in trust;

 

   

compensate and indemnify the trustee; and

 

   

appoint any successor trustee.

In order to exercise our rights to be discharged with respect to a series, we must deposit with the trustee money or government obligations sufficient to pay all the principal of, the premium, if any, and interest on, the debt securities of the series on the dates payments are due.

Form, Exchange, and Transfer

We will issue the debt securities of each series only in fully registered form without coupons and, unless we otherwise specify in the applicable prospectus supplement, in denominations of $1,000 and any integral multiple thereof. The indentures provide that we may issue debt securities of a series in temporary or permanent global form and as book-entry securities that will be deposited with, or on behalf of, The Depository Trust Company or another depositary named by us and identified in a prospectus supplement with respect to that series.

At the option of the holder, subject to the terms of the indentures and the limitations applicable to global securities described in the applicable prospectus supplement, the holder of the debt securities of any series can exchange the debt securities for other debt securities of the same series, in any authorized denomination and of like tenor and aggregate principal amount.

Subject to the terms of the indentures and the limitations applicable to global securities set forth in the applicable prospectus supplement, holders of the debt securities may present the debt securities for exchange or for registration of transfer, duly endorsed or with the form of transfer endorsed thereon duly executed if so required by us or the security registrar, at the office of the security registrar or at the office of any transfer agent designated by us for this purpose. Unless otherwise provided in the debt securities that the holder presents for transfer or exchange or in the applicable indenture, we will make no service charge for any registration of transfer or exchange, but we may require payment of any taxes or other governmental charges.

We will name in the applicable prospectus supplement the security registrar, and any transfer agent in addition to the security registrar, that we initially designate for any debt securities. We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.

If we elect to redeem the debt securities of any series, we will not be required to:

 

   

issue, register the transfer of, or exchange any debt securities of that series during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of any debt securities that may be selected for redemption and ending at the close of business on the day of the mailing; or

 

   

register the transfer of or exchange any debt securities so selected for redemption, in whole or in part, except the unredeemed portion of any debt securities we are redeeming in part.

Information Concerning the Debenture Trustee

The debenture trustee, other than during the occurrence and continuance of an event of default under the applicable indenture, undertakes to perform only those duties as are specifically set forth in the applicable indenture. Upon an event of default under an indenture, the debenture trustee under such indenture must use the

 

21


Table of Contents

same degree of care as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to this provision, the debenture trustee is under no obligation to exercise any of the powers given it by the indentures at the request of any holder of debt securities unless it is offered reasonable security and indemnity against the costs, expenses and liabilities that it might incur.

Payment and Paying Agents

Unless we otherwise indicate in the applicable prospectus supplement, we will make payment of the interest on any debt securities on any interest payment date to the person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular record date for the interest.

We will pay principal of and any premium and interest on the debt securities of a particular series at the office of the paying agents designated by us, except that unless we otherwise indicate in the applicable prospectus supplement, will we make interest payments by check which we will mail to the holder. Unless we otherwise indicate in a prospectus supplement, we will designate the corporate trust office of the debenture trustee in the City of New York as our sole paying agent for payments with respect to debt securities of each series. We will name in the applicable prospectus supplement any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.

All money we pay to a paying agent or the debenture trustee for the payment of the principal of or any premium or interest on any debt securities which remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of the security thereafter may look only to us for payment thereof.

Governing Law

The indentures and the debt securities will be governed by and construed in accordance with the laws of the State of New York, except to the extent that the Trust Indenture Act is applicable.

Subordination of Subordinated Debt Securities

Our obligations pursuant to any subordinated debt securities will be unsecured and will be subordinate and junior in priority of payment to certain of our other indebtedness to the extent described in a prospectus supplement. The subordinated indenture does not limit the amount of senior indebtedness we may incur. It also does not limit us from issuing any other secured or unsecured debt.

DESCRIPTION OF RIGHTS

General

We may issue rights to our stockholders to purchase shares of our common stock, preferred stock or the other securities described in this prospectus. We may offer rights separately or together with one or more additional rights, debt securities, preferred stock, common stock or warrants, or any combination of those securities in the form of units, as described in the applicable prospectus supplement. Each series of rights will be issued under a separate rights agreement to be entered into between us and a bank or trust company, as rights agent. The rights agent will act solely as our agent in connection with the certificates relating to the rights of the series of certificates and will not assume any obligation or relationship of agency or trust for or with any holders of rights certificates or beneficial owners of rights. The following description sets forth certain general terms and provisions of the rights to which any prospectus supplement may relate. The particular terms of the rights to which any prospectus supplement may relate and the extent, if any, to which the general provisions may apply to the rights so offered will be described in the applicable prospectus supplement. To the extent that any particular terms of the rights, rights agreement or rights certificates described in a prospectus supplement differ from any of the terms described below, then the terms described below will be deemed to have been superseded by that prospectus supplement. We encourage you to read the applicable rights agreement and rights certificate for additional information before you decide whether to purchase any of our rights. We will provide in a prospectus supplement the following terms of the rights being issued:

 

   

the date of determining the stockholders entitled to the rights distribution;

any applicable material U.S. federal income tax considerations; and

 

   

any other terms of the rights, including terms, procedures and limitations relating to the distribution, exchange and exercise of the rights, as applicable.

Each right will entitle the holder of rights to purchase for cash the principal amount of shares of common stock, preferred stock or other securities at the exercise price provided in the applicable prospectus supplement. Rights may be exercised at any time up to the close of business on the expiration date for the rights provided in the applicable prospectus supplement.

Holders may exercise rights as described in the applicable prospectus supplement. Upon receipt of payment and the rights certificate properly completed and duly executed at the corporate trust office of the rights agent or

Table of Contents

any other office indicated in the prospectus supplement, we will, as soon as practicable, forward the shares of common stock, preferred stock or other securities, as applicable, purchasable upon exercise of the rights.

DESCRIPTION OF UNITS

The following description, together with the additional information that we include in any applicable prospectus supplements summarizes the material terms and provisions of the units that we may offer under this prospectus. While the terms we have summarized below will apply generally to any units that we may offer under this prospectus, we will describe the particular terms of any series of units in more detail in the applicable prospectus supplement. The terms of any units offered under a prospectus supplement may differ from the terms described below.

We will incorporate by reference from reports that we file with the SEC, the form of unit agreement that describes the terms of the series of units we are offering, and any supplemental agreements, before the issuance of the related series of units. The following summaries of material terms and provisions of the units are subject to, and qualified in their entirety by reference to, all the provisions of the unit agreement and any supplemental agreements applicable to a particular series of units. We urge you to read the applicable prospectus supplements related to the particular series of units that we may offer under this prospectus, as well as any related free writing prospectuses and the complete unit agreement and any supplemental agreements that contain the terms of the units.

General

We may issue units consisting of common stock, preferred stock, one or more debt securities, warrants or rights for the purchase of common stock, preferred stock and/or debt securities in one or more series, in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each security included in the unit. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

We will describe in the applicable prospectus supplement the terms of the series of units being offered, including:

 

   

the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

 

   

any provisions of the governing unit agreement that differ from those described below; and

 

   

any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units.

The provisions described in this section, as well as those set forth in any prospectus supplement or as described under “Description of Common Stock,” “Description of Preferred Stock,” “Description of Debt Securities,” “Description of Warrants,” and “Description of Rights” will apply to each unit, as applicable, and to any common stock, preferred stock, debt security, warrant or right included in each unit, as applicable.

Unit Agent

The name and address of the unit agent, if any, for any units we offer will be set forth in the applicable prospectus supplement.

Issuance in Series

We may issue units in such amounts and in such numerous distinct series as we determine.

Enforceability of Rights by Holders of Units

Each unit agent will act solely as our agent under the applicable unit agreement and will not assume any obligation or relationship of agency or trust with any holder of any unit. A single bank or trust company may act

 

26


Table of Contents

as unit agent for more than one series of units. A unit agent will have no duty or responsibility in case of any default by us under the applicable unit agreement or unit, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a unit may, without the consent of the related unit agent or the holder of any other unit, enforce by appropriate legal action its rights as holder under any security included in the unit.

CERTAIN PROVISIONS OF DELAWARE LAW AND OF THE COMPANY’S CERTIFICATE OF INCORPORATION AND BYLAWS

Anti-Takeover Provisions

The provisions of Delaware law, our restated certificate of incorporation and our restated bylaws may have the effect of delaying, deferring or discouraging another person from acquiring control of our company.

Delaware Law

Section 203 of the Delaware General Corporation Law prevents some Delaware corporations from engaging, under some circumstances, in a business combination, which includes a merger or sale of at least 10% of the corporation’s assets with any interested stockholder, meaning a stockholder who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of the corporation’s outstanding voting stock, unless:

 

   

the transaction is approved by the board of directors prior to the time that the interested stockholder became an interested stockholder;

 

   

upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced; or

 

   

at or subsequent to such time that the stockholder became an interested stockholder the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders by at least two-thirds of the outstanding voting stock that is not owned by the interested stockholder.

If Section 203 applied to us, the restrictions could prohibit or delay mergers or other takeover or change in control attempts and, accordingly, could discourage attempts to acquire us.

Restated Certificate of Incorporation and Restated Bylaw Provisions

Our restated certificate of incorporation and our restated bylaws include a number of provisions that may have the effect of deterring hostile takeovers or delaying or preventing changes in control of our management team, including the following:

 

   

Board of Directors Vacancies. Our restated certificate of incorporation and restated bylaws authorize only our board of directors to fill vacant directorships. In addition, the number of directors constituting the full board of directors shall not be changed without the affirmative vote of the board of directors. These provisions hinder a stockholder from increasing the size of our board of directors and gaining control of our board of directors by filling the resulting vacancies with its own nominees.

 

   

Classified Board. Our restated certificate of incorporation and proposed restated bylaws provide that our board of directors is classified into three classes of directors. The existence of a classified board could delay a successful tender offeror from obtaining majority control of our board of directors, and the prospect of that delay might deter a potential offeror. Pursuant to Delaware law, the directors of a corporation having a classified board may be removed by the stockholders only for cause, and pursuant to our restated certificate of incorporation, by the affirmative vote of at least sixty-six and two thirds percent (66 2/3%) of the votes that all stockholders would be entitled to cast in an election of directors. In addition, stockholders will not be permitted to cumulate their votes for the election of directors.

 

   

Stockholder Action; Special Meeting of Stockholders. Our restated certificate of incorporation provides that our stockholders may not take action by written consent but may only take action at annual or special meetings of our stockholders. Our restated certificate of incorporation further provides that special meetings of our stockholders may be called only by a majority of our board of

 

28


Table of Contents
 

directors, the chairman of our board of directors and our chief executive officer, or upon the request of the holders of a majority of our issued and outstanding common stock.

 

   

Advance Notice Requirements for Stockholder Proposals and Director Nominations. Our restated bylaws provide advance notice procedures for stockholders seeking to bring business before our annual meeting of stockholders, or to nominate candidates for election as directors at our annual meeting of stockholders. Our restated bylaws also specify certain requirements regarding the form and content of a stockholder’s notice. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders.

 

   

Stockholders. Our restated bylaws also specify certain requirements regarding the form and content of a stockholder’s notice. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders.

 

   

Issuance of Undesignated Preferred Stock. Under our restated certificate of incorporation, our board of directors has the authority, without further action by the stockholders, to issue up to 10,000,000 shares of undesignated preferred stock with rights and preferences, including voting rights, designated from time to time by the board of directors. The existence of authorized but unissued shares of preferred stock enables our board of directors to render more difficult or to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise.

 

   

Exclusive Forum. Our restated certificate of incorporation specifies that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for: (i) any derivative action or proceeding brought on behalf of the corporation; (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the corporation to the corporation or the corporation’s stockholders; (iii) any action asserting a claim arising pursuant to any provision of the DGCL; and (iv) any action asserting a claim governed by the internal affairs doctrine. We believe this provision benefits us by providing increased consistency in the application of Delaware law by chancellors particularly experienced in resolving corporate disputes, efficient administration of cases on a more expedited schedule relative to other forums and protection against the burdens of multi-forum litigation. However, the provision may have the effect of discouraging lawsuits against our directors and officers. The enforceability of similar choice of forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that, in connection with any applicable action brought against us, a court could find the choice of forum provisions contained in our restated certificate of incorporation to be inapplicable or unenforceable in such action.

Limitation of Liability and Indemnification

As permitted by Delaware law, we have adopted provisions in our certificate of incorporation that limit or eliminate the personal liability of our directors. Our restated certificate of incorporation limits the liability of directors to the maximum extent permitted by Delaware law. Delaware law provides that directors of a corporation will not be personally liable for monetary damages for breaches of their fiduciary duties as directors, except liability for:

 

   

any breach of the director’s duty of loyalty to us or our stockholders;

 

   

any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

 

   

any unlawful payments related to dividends or unlawful stock repurchases, redemptions or other distributions; or

 

   

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

 

29


Table of Contents

These limitations do not apply to liabilities arising under federal securities laws and do not affect the availability of equitable remedies, including injunctive relief or rescission. If Delaware law is amended to authorize the further elimination or limiting of a director, then the liability of our directors will be eliminated or limited to the fullest extent permitted by Delaware law as so amended.

As permitted by Delaware law, our certificate of incorporation also provides that:

 

   

we will indemnify our directors and officers to the fullest extent permitted by law;

 

   

we may indemnify our other employees and other agents to the same extent that we indemnify our officers and directors, unless otherwise determined by our board of directors; and

 

   

we will advance expenses to our directors and officers in connection with legal proceedings in connection with a legal proceeding to the fullest extent permitted by law.

The indemnification provisions contained in our certificate of incorporation are not exclusive. In addition, we have entered into indemnification agreements with each of our directors and executive officers. Each of these indemnification agreements provides, among other things, that we will indemnify such director or executive officer to the fullest extent permitted by law for claims arising in his or her capacity as a director or officer, as applicable, provided that he or she acted in good faith and in a manner that he or she reasonably believed to be in, or not opposed to, our best interests and, with respect to any criminal proceeding, had no reasonable cause to believe that his or her conduct was unlawful. Each of these indemnification agreements provide that in the event that we do not assume the defense of a claim against a director or officer, as applicable, we will be required to advance his or her expenses in connection with his or her defense, provided that he or she undertakes to repay all amounts advanced if it is ultimately determined that he or she is not entitled to be indemnified by us.

We believe that these provisions and agreements are necessary to attract and retain qualified persons as directors and officers. Insofar as indemnification for liabilities arising under the Securities Act of 1933, which we refer to as the Securities Act, may be permitted to directors, officers or persons controlling our company pursuant to the foregoing provisions, we understand that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

In addition, we maintain standard policies of insurance under which coverage is provided to our directors and officers against losses arising from claims made by reason of breach of duty or other wrongful act, and to us with respect to payments which may be made by us to such directors and officers pursuant to the above indemnification provisions or otherwise as a matter of law.

The foregoing discussion of our restated certificate of incorporation, restated bylaws, indemnification agreements and Delaware law is not intended to be exhaustive and is qualified in its entirety by such restated certificate of incorporation, restated bylaws, indemnification agreements or law.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

LEGAL MATTERS

Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., Boston, Massachusetts, will pass upon the validity of the issuance of the securities to be offered by this prospectus.

About F-star Therapeutics, Inc.

We are a clinical-stage biopharmaceutical company dedicated to developing next generation immunotherapies to transform the lives of patients with cancer. Our goal is to offer patients better and more durable benefits than currently available immuno-oncology treatments by developing medicines that seek to block tumor immune evasion. Through our proprietary tetravalent, bispecific natural antibody (mAb²) format, our mission is to generate highly differentiated medicines with monoclonal antibody-like manufacturability, good safety and tolerability. With four distinct binding sites in a natural human antibody format, we believe our proprietary technology will overcome many of the challenges facing current immuno-oncology therapies, due to the strong pharmacology enabled by tetravalent bispecific binding In 2020, combined sales of current immuno-oncology therapies were estimated to be approximately $28.7 billion. Despite the commercial success of currently approved immuno-oncology products, only approximately 20% of patients realize a long-lasting benefit from these treatments, leaving a large, unserved patient population without effective treatment options.

We believe the novel tetravalent and natural human antibody formats of our mAb2 bispecific antibodies have the potential to focus immune activation to enhance efficacy and reduce systemic toxicities.

Our mission is to generate highly differentiated, first and/or best-in-class product candidates that will transform the lives of patients with cancer. The key elements of our strategy include:

 

   

Rapidly accelerating the clinical development of our three novel mAb2 product candidates and novel cyclic dinucleotide, SB 11285, to treat a range of advanced cancers. We believe our mAb2 product candidates represent potentially best-in-class immuno-oncology therapies that address a variety of patients with cancer inadequately treated with existing therapies. We believe FS118, which is being evaluated in a proof of concept trial in PD-1/PD-L1 acquired resistance head and neck cancer patients, has the potential to provide significant clinical benefit through its dual-checkpoint inhibitor targets (LAG-3 and PD-L1). In addition to FS118, we are currently evaluating FS120, FS222 and SB 11285 for safety, tolerability and efficacy in Phase 1 clinical trials in patients with advanced cancers with the potential to address multiple immune evasion pathways that limit the effect of current immuno-oncology therapies.

 

   

Initially focusing our development strategy on tumors where checkpoint inhibitors are currently utilized but are poor long-term treatment options, and then subsequently broadening to other tumor types and potentially, first-line therapies. Our early-stage clinical trials include or will include a broad range of tumor types to evaluate safety, tolerability and dosing, as well as early signals of efficacy. Following these early-stage clinical trials, we intend to employ a patient selection strategy, using biomarkers to focus further development on targeted patient subsets. These subsets are expected to include patients with high cancer target co-expression and/or resistance to current checkpoint

therapies. We believe our mAb2 bispecific antibodies and SB 11285 may also ultimately deliver therapeutic benefit in a broader range of tumors, expanding beyond the initial indications we may pursue. We believe our development strategy best serves the patient, can be efficiently pursued by our organization and, is likely to lead to a rapid development strategy and regulatory pathway to market. For example, we have identified several tumor types which have a strong fit with the potential FS118 mechanism of action, including appropriate target expression, that would be candidates for accelerated approval pathways.

 

   

Leveraging the transformational potential of our modular antibody technology platform to create a leading immuno-oncology pipeline of differentiated clinical assets capable of improving patient outcomes. Our proprietary mAb2 bispecific antibodies have a number of potential advantages, compared to other modalities, resulting from their novel tetravalent and natural human antibody formats, which we believe will result in improved efficacy, minimized toxicity and simplified manufacturability. We believe our technology has the potential to be matched with any antibody domain in a modular “plug-and-play” approach to further expand our innovative pipeline of mAb2 product candidates. We believe these benefits provide multiple opportunities to consistently generate clinical candidates that could potentially address the needs of patients who are without adequate therapeutic options.

 

   

Leveraging and continuing to build our extensive intellectual property portfolio in order to protect our dominant position in mAb2 bispecific antibodies and our STING agonist program. We have built an extensive patent portfolio around our mAb2 technology and product pipeline. In addition, we have STING pathway-related filings, including those of a patent family relating to the composition of matter of the STING agonist SB 11285. This patent estate relates to our mAb2 bispecific format and STING agonist program and aims to provide us with robust intellectual property exclusivity and prohibit use of our technology by third parties. We intend to continue to seek additional patent protection as we develop additional novel mAb2 product candidates.

We have collaborative partnerships with Ares Trading S.A., an affiliate of Merck KGaA, Darmstadt, Germany, and Denali Therapeutics Inc., which enable us to further validate our technological approach. Since inception, the F-star entities which have entered into collaborations, which are F-star Alpha Limited, F-star Beta Limited, F-star Biotechnology Limited and F-star Delta Limited, have collectively generated over $167 million in revenue to date, $90 million of which has been included in the cumulative equity of the Company. We believe that these partnerships will provide both continued validation and ongoing revenue as we continue to advance our proprietary pipeline.

We are led by a team of highly experienced executives, clinicians, scientists and advisors with notable expertise in antibody research, immuno-oncology, antibody manufacturing and clinical development. Our team has spent over a decade developing our proprietary mAb2 technology into a robust drug discovery platform. Our team has collectively worked on the development of 20 marketed products and has worked at companies including AstraZeneca, BMS, Celgene Corporation, Domantis Ltd., Eli Lilly, GSK, Immunocore Ltd. and Pfizer Inc.

Our Pipeline

FS118

Our most advanced product candidate, FS118, is currently being evaluated in a proof-of-concept trial in PD-1/PD-L1 acquired resistance head and neck cancer patients. FS118 is a tetravalent mAb2 bispecific antibody targeting two receptors, PD-L1 and LAG-3, both of which are established pivotal targets in immuno-oncology. Phase 1 data from 43 heavily pre-treated patients with advanced cancer, who have failed PD-1/PD-L1 therapy, showed that administration of FS118 was well-tolerated with no dose limiting toxicities up to 20/mg/kg. In

addition, a disease control rate (“DCR”), defined as either a complete response, partial response or stable disease, of 49% was observed in 39 evaluable patients receiving dose levels of FS118 at 1 mg/kg or greater. In acquired resistance patients, DCR was 59% (16 out of 27 patients) and long-term (greater than six months) disease control was observed in six of these patients. We expect to provide an update from the proof-of-concept trial in PD-1/PD-L1 acquired resistance head and neck cancer patients in H1 2022.

FS120

We initiated a Phase 1 clinical trial for FS120 in patients with advanced cancers in late 2020. FS120 is a first-in-class dual agonist bispecific antibody, an antibody that stimulates two immune activating pathways, which we believe has the potential to overcome cancer resistance by simultaneously targeting CD137 (4-1BB) and OX40, two receptors present on the surface of tumor-infiltrating lymphocytes. Unlike checkpoint inhibitors, the mechanism of action of FS120 is designed to trigger a positive signal that enhances multiple mechanisms essential for killing tumor cells. FS120 has a natural human antibody format. It is engineered to abrogate Fc gamma receptor binding and effector activity, providing increased specificity and, we believe, superior performance while reducing toxicity through engineered conditional, crosslink-dependent activation upon binding to both CD137 and OX40. We expect to enroll up to 70 patients in a Phase 1 dose escalation clinical trial to assess the safety, tolerability and efficacy of FS120 in patients with advanced malignancies and include those patients who have high co-expression of CD137 and OX40. We expect to provide an update on study progress in mid-2021.

FS222

The third bispecific program from our proprietary platform, FS222, began a Phase 1 clinical trial for FS222 in patients with advanced cancers in late 2020. FS222 has the potential to provide clinical benefit through multiple mechanisms based on its tetravalency. These include: (1) blocking the PD-1/PD-L1 immunosuppressive pathway and (2) conditionally clustering and crosslinking CD137 receptors, resulting in activation of CD137 in a PD-L1-dependent manner. We believe this dual mechanism of action could lead to strong anti-tumor activity of FS222 inclding benefits in cancers with low PD-L1 expression. Our preclinical data shows that FS222 has the potential to be more effective than a combination of traditional PD-L1 and CD137 antibodies. FS222 has been designed with specific mutations to make its activity independent of binding to Fc gamma receptors. PD-L1 is frequently highly expressed on cells within cancer tissue compared to non-cancer tissue. Therefore, we believe this will make FS222 immune activation conditional within cancer tissue, limit potential systemic toxicities and lead to safety benefits. We expect to initiate a Phase 1 expansion cohort to measure pharmacokinetic (PK)/ pharmacodynamic (PD) for FS222 in Q4 2021.

SB 11285

In addition to the mAb2 product candidates, we are evaluating SB 11285 in a Phase 1 clinical trial as an intravenously (IV) administered monotherapy, and in combination with an anti-PD-L1 antibody, in patients with advanced cancers. SB 11285 is a next generation cyclic dinucleotide-based STING agonist with efficient cellular uptake. We believe that SB 11285 has the potential to produce anti-tumor activity by inducing interferon pathways and activating the innate and, indirectly, the adaptive immune system. We believe combining SB 11285 with PD-L1 therapy will further enhance anti-tumor activity. SB 11285 has been designed to allow IV administration which we believe will increase its applicability to treat a wide variety of advanced cancers. We expect to report an update on the trial in mid-2021.

Research

The tetravalent format of FS118 simultaneously targets two immune checkpoint receptors, LAG-3 and PD-L1, to directly address known tumor evasion pathways. FS118 is currently being evaluated in a

Table of Contents

proof-of-concept trial in PD-1/PD-L1 acquired resistance head and neck cancer patients. In the Phase 1 clinical trial in heavily pre-treated patients with advanced cancer who have failed PD-1/PD-L1 therapy it was demonstrated that administration of FS118 was well-tolerated and has provided long-term disease control in these patients. Our clinical pipeline also includes FS120, which targets CD137 and OX40 and FS222, which targets PD-L1 and CD137 and SB 11285 which targets the STING pathway. FS120 and FS222 are currently being evaluated for safety, tolerability and efficacy in Phase 1 clinical trials in patients with advanced cancers. SB 11285 is a next generation cyclic dinucleotide-based STING agonist that is being evaluated for safety, tolerability and efficacy as a monotherapy and in combination with an anti-PD-L1 antibody in a Phase 1 clinical trial with advanced cancers. Our portfolio includes further preclinical and clinical programs that are being developed by our partners.

Our Platform

We leverage our proprietary mAb2 technology to build our portfolio of wholly-owned immuno-oncology mAb2 product candidates and has generated a panel of early stage Fcab building blocks against a range of targets with the potential to go beyond immuno-oncology. These Fcab building blocks have been used to generate not only bispecific antibodies but also trispecific antibodies. We have over 230 granted patents and over 150 pending applications relating to our mAb2 technology and product pipeline. We believe we have a leading position in mAb2 bispecific antibody development, and third parties are prohibited from utilizing our mAb2 technology without obtaining a license from us.

Impact of COVID-19

In March 2020, the World Health Organization declared the novel strain of coronavirus (COVID-19) a global pandemic and recommended containment and mitigation measures worldwide. The COVID-19 pandemic has been evolving, and to date has led to the implementation of various responses, including government-imposed quarantines, travel restrictions and other public health safety measures.

Management continues to closely monitor the impact of the COVID-19 pandemic on all aspects of the business, including how it will impact operations and the operations of customers, vendors, and business partners. Management took action in April 2020 to temporarily furlough some of its workforce which was reimbursed for $0.5 million by the Coronavirus Job Retention Scheme in the UK. Management did see approximately a three-to-six-month delay in the operationalization of its clinical trials for FS118, FS120, FS222 and SB 11285. The extent to which COVID-19 impacts the future business, results of operation and financial condition will depend on future developments, which are highly uncertain and cannot be predicted with confidence at this time, such as the continued duration of the outbreak, new information that may emerge concerning the severity or other strains of COVID-19 or the effectiveness of actions to contain COVID-19 or treat its impact, among others. If the we or any of the third parties with which we engage, however, were to experience shutdowns or other business disruptions, the ability to conduct our business in the manner and on the timelines presently planned could be materially and negatively affected, which could have a material adverse impact on business, results of operation and financial condition. The estimates of the impact on the Company’s business may change based on new information that may emerge concerning COVID-19 and the actions to contain it or treat its impact and the economic impact on local, regional, national, and international markets.

Risks Related to This Offering

Our management will have broad discretion over the use of the net proceeds from this offering, and you may not agree with how we use the proceeds, and the proceeds may not be invested successfully.

Our management will have broad discretion as to the use of the net proceeds from this offering and could use them for purposes other than those contemplated at the time of this offering. Accordingly, you are relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds will be used appropriately. It is possible that the proceeds will be invested in a way that does not yield a favorable, or any, return for F-star.

Purchasers will experience immediate dilution in the book value per share of the common stock purchased in the offering.

The shares sold in this offering, if any, will be sold from time to time at various prices. However, we expect that the offering price of our common stock will be substantially higher than the net tangible book value per share of our outstanding common stock. After giving effect to the sale of shares of our common stock in the aggregate amount of $50,000,000.00 at an assumed offering price of $9.22 per share, the last reported sale price of our common stock on March 29, 2021 on the Nasdaq Capital Market, and after deducting commissions and estimated offering expenses, our as adjusted net tangible book value as of December 31, 2020 would have been approximately $54.5 million or approximately $3.75 per share. This represents an immediate increase in net tangible book value of approximately $3.06 per share to our existing stockholders and an immediate dilution in as adjusted net tangible book value of approximately $5.47 per share to purchasers of our common stock in this offering.

In addition to this offering, subject to market conditions and other factors, we may pursue additional equity financings in the future, including future public offerings or future private placements of equity securities or securities convertible into or exchangeable for equity securities. Further, the exercise of outstanding options or warrants could result in further dilution to investors and any additional shares issued in connection with acquisitions, should we choose to pursue any, will result in dilution to investors. In addition, the market price of our common stock could fall as a result of resales of any of these shares of common stock due to an increased number of shares available for sale in the market.

You may experience future dilution as a result of future equity offerings.

In order to raise additional capital, we may in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock. We cannot assure you that we will be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock or other securities convertible into or exchangeable for our common stock in future transactions may be higher or lower than the price per share in this offering.

Our stock price is and may continue to be volatile and you may not be able to resell our securities at or above the price you paid.

The market price for our common stock is volatile and may fluctuate significantly in response to a number of factors, most of which we cannot control, such as quarterly fluctuations in financial results, the timing and our ability to advance the development of our product candidates or changes in securities analysts’ recommendations could cause the price of our stock to fluctuate substantially. Each of these factors, among others, could harm your investment in our common stock and could result in your being unable to resell the common stock that you purchase at a price equal to or above the price you paid.

Sales of a significant number of shares of our common stock in the public markets, or the perception that such sales could occur, could depress the market price of our common stock.

Sales of a substantial number of shares of our common stock in the public markets could depress the market price of our common stock and impair our ability to raise capital through the sale of additional equity securities. We cannot predict the effect that future sales of our common stock would have on the market price of our common stock.

Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall.

Sales of a substantial number of shares of our common stock in the public market or the perception that these sales might occur could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that such sales may have on the prevailing market price of our common stock. In addition, the sale of substantial amounts of our common stock could adversely impact its price. The sale or the availability for sale of a large number of shares of our common stock in the public market could cause the price of our common stock to decline.

It is not possible to predict the aggregate proceeds resulting from sales made under the sales agreement.

Subject to certain limitations in the sales agreement between us and SVB Leerink and compliance with applicable law, we have the discretion to deliver a placement notice to SVB Leerink at any time throughout the term of the sales agreement. The number of shares that are sold through SVB Leerink after delivering a placement notice will fluctuate based on a number of factors, including the market price of our common stock during the sales period, any limits we may set with SVB Leerink in any applicable placement notice and the demand for our common stock. Because the price per share of each share sold pursuant to the sales agreement will fluctuate over time, it is not currently possible to predict the aggregate proceeds to be raised in connection with sales under the sales agreement.

The common stock offered hereby will be sold in “at the market offerings” and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares in this offering at different times will likely pay different prices, and accordingly may experience different levels of dilution and different outcomes in their investment results. We

will have discretion, subject to market demand, to vary the timing, prices and number of shares sold in this offering. In addition, subject to the final determination by our board of directors or any restrictions we may place in any applicable placement notice, there is no minimum or maximum sales price for shares to be sold in this offering. Investors may experience a decline in the value of the shares they purchase in this offering as a result of sales made at prices lower than the prices they paid.

If securities or industry analysts do not publish an adequate amount of research, or publish inaccurate or unfavorable research, about our business, our stock price and trading volume could decline.

The trading market for our common stock will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. Securities and industry analysts may not publish an adequate amount of research on us, which may negatively impact the trading price for our stock. In addition, if one or more of the analysts who cover us downgrade our stock or publish inaccurate or unfavorable research about our business, our stock price would likely decline. Further, if our operating results fail to meet the forecasts of analysts, our stock price would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for our stock could decrease, which might cause our stock price and trading volume to decline.

USE OF PROCEEDS

We may issue and sell shares of our common stock having aggregate sale proceeds of up to $50,000,000.00 from time to time. Because there is no minimum offering amount required to be sold in connection with this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. We intend to use any net proceeds from the sale of common stock under this prospectus for general corporate purposes, including, but not limited to, clinical trials, research and development activities, working capital, capital expenditures, investments, acquisitions, should we choose to pursue any, and collaborations. The amounts and timing of our actual expenditures will depend on numerous factors, including the progress of our clinical trials and other development efforts and other factors described under “Risk Factors” in this prospectus and the documents incorporated by reference herein, as well as the amount of cash used in our operations. As a result, our management will have broad discretion to allocate the net proceeds, if any, we receive in connection with securities offered pursuant to this prospectus for any purpose.

DILUTION

If you invest in our common stock, your interest will be diluted to the extent of the difference between the price per share of our common stock you pay in this offering and the as adjusted net tangible book value per share of our common stock immediately after this offering.

As of December 31, 2020, our net tangible book value was approximately $6.3 million, or $0.69 per share of common stock. Net tangible book value per share represents the amount of our total tangible assets less total liabilities, divided by 9,100,117, the number of shares of common stock outstanding as of December 31, 2020.

After giving effect to the sale of our common stock in the aggregate amount of $50 million at an assumed offering price of $9.22 per share, the last reported sale price of our common stock on the Nasdaq Capital Market on March 29, 2021, and after deducting commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of December 31, 2020 would have been $54.5 million, or $3.75 per share of common stock. This amount would represent an immediate increase in net tangible book value of $3.06 per share to our existing stockholders and an immediate dilution in net tangible book value of approximately $5.47 per share to new investors in this offering.

The following table illustrates this calculation on a per share basis. The as adjusted information is illustrative only and will adjust based on the actual price to the public, the actual number of shares sold and other terms of the offering determined at the time shares of our common stock are sold pursuant to this prospectus. The shares sold in this offering, if any, will be sold from time to time at various prices.

 

Assumed offering price per share

   $ 9.22  

Net tangible book value per share as of December 31, 2020

   $ 0.69  

Increase in net tangible book value per share attributable to this offering

   $ 3.06  

As adjusted net tangible book value per share after this offering

   $ 3.75  

Dilution per share to new investors participating in this offering

   $ 5.47  

The table above assumes for illustrative purposes that an aggregate of 5,422,993 shares of our common stock are sold pursuant to this prospectus at a price of $9.22 per share, the last reported sale price of our common stock on the Nasdaq Capital Market on March 29, 2021, for aggregate gross proceeds of $50 million. The shares are being sold from time to time at various prices pursuant to the sales agreement with SVB Leerink. A $1.00 increase in the assumed offering price of $9.22 per share, which was the last reported sale price of our common stock on the Nasdaq Capital Market on March 29, 2021, would increase dilution per share to purchasers by approximately $5.33, after deducting commissions and estimated offering expenses payable by us. A $1.00 decrease in the assumed offering price of $9.22 per share, which was the last reported sale price of our common stock on the Nasdaq Capital Market on March 29, 2021, would decrease dilution per share to purchasers by approximately $6.32, after deducting commissions and estimated offering expenses payable by us.

The above discussion and table are based on 9,100,117 shares of our common stock issued and outstanding as of December 31, 2020, and excludes, as of that date:

 

   

603,348 shares issuable upon the exercise of options outstanding as of December 31, 2020 at a weighted average exercise price of $2.94 per share;

 

   

678,949 shares reserved for issuance under the Amended and Restated 2015 Stock Option Plan as of December 31, 2020;

 

   

27,542 shares reserved for issuance under our 2019 Equity Incentive Plan as of December 31, 2020; and

 

   

144,384 shares issuable upon the exercise of warrants outstanding as of December 31, 2020 at a weighted average exercise price of $28.22 per share.

 

S-14


Table of Contents

To the extent that outstanding options or warrants are exercised, you will experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities may result in further dilution to our stockholders.

As of December 31, 2020, we had 9,100,117 shares of common stock outstanding with approximately 149 common stockholders of record and no shares of preferred stock outstanding.

The following summary of certain provisions of our common stock does not purport to be complete. You should refer to the section of this prospectus entitled “Certain Provisions of Delaware Law and of our Certificate of Incorporation and Bylaws” and our amended and restated certificate of incorporation and our amended and restated bylaws, both of which are included as exhibits to the registration statement of which this prospectus is a part. The summary below is also qualified by provisions of applicable law.

Common Stock

We are authorized to issue one class of common stock. Holders of our common stock are entitled to one vote for each share of common stock held of record for the election of directors and on all matters submitted to a vote of stockholders, except matters that relate only to one or more of the series of our preferred stock, and no holder has cumulative voting rights. Accordingly, the holders of a majority of the shares of common stock entitled to vote in any election of directors can elect all of the directors standing for election, if they so choose. Subject to preferences that may be applicable to any then outstanding preferred stock, holders of our common stock are entitled to receive dividends ratably, if any, as may be declared by our board of directors out of legally available funds, subject to any preferential dividend rights of any preferred stock then outstanding. Upon our dissolution, liquidation or winding up, holders of our common stock are entitled to share ratably in our net assets legally available after the payment of all our debts and other liabilities, subject to the preferential rights of any preferred stock then outstanding. Holders of our common stock have no preemptive, subscription, redemption or conversion rights. The rights, preferences and privileges of holders of common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that are currently designated and issued or that we may designate and issue in the future. Except as described under “Certain Provisions of Delaware Law and of the Company’s Certificate of Incorporation and Bylaws—Anti-Takeover Provisions” below, a majority vote of the holders of common stock is generally required to take action under our amended and restated certificate of incorporation and amended and restated bylaws.

Preferred Stock

Our board of directors is authorized, without action by the stockholders, to designate and issue up to an aggregate of 10,000,000 shares of preferred stock, par value $0.0001 per share, in one or more series. Our board of directors can designate the rights, preferences and privileges of the shares of each series and any of its qualifications, limitations or restrictions. Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of common stock.

Stock Options and Warrants

As of December 31, 2020, we had outstanding warrants to purchase 144,384 shares of our common stock at exercise prices ranging from $8.32 to $60.00 per share. Warrants to purchase 7,087 shares of our common stock will expire on May 5, 2021, 71,047 warrants will expire on November 21, 2021, 3,750 warrant will expire on September 21, 2021 and 62,500 warrants will expire on September 19, 2025.

CERTAIN PROVISIONS OF DELAWARE LAW AND OF THE COMPANY’S CERTIFICATE OF INCORPORATION AND BYLAWS

Anti-Takeover Provisions

The provisions of Delaware law, our restated certificate of incorporation and our restated bylaws may have the effect of delaying, deferring or discouraging another person from acquiring control of our company.

Delaware Law

Section 203 of the Delaware General Corporation Law prevents some Delaware corporations from engaging, under some circumstances, in a business combination, which includes a merger or sale of at least 10% of the corporation’s assets with any interested stockholder, meaning a stockholder who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of the corporation’s outstanding voting stock, unless:

 

   

the transaction is approved by the board of directors prior to the time that the interested stockholder became an interested stockholder;

 

   

upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced; or

 

   

at or subsequent to such time that the stockholder became an interested stockholder the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders by at least two-thirds of the outstanding voting stock that is not owned by the interested stockholder.

If Section 203 applied to us, the restrictions could prohibit or delay mergers or other takeover or change in control attempts and, accordingly, could discourage attempts to acquire us.

Restated Certificate of Incorporation and Restated Bylaw Provisions

Our restated certificate of incorporation and our restated bylaws include a number of provisions that may have the effect of deterring hostile takeovers or delaying or preventing changes in control of our management team, including the following:

 

   

Board of Directors Vacancies. Our restated certificate of incorporation and restated bylaws authorize only our board of directors to fill vacant directorships. In addition, the number of directors constituting the full board of directors shall not be changed without the affirmative vote of the board of directors. These provisions hinder a stockholder from increasing the size of our board of directors and gaining control of our board of directors by filling the resulting vacancies with its own nominees.

 

   

Classified Board. Our restated certificate of incorporation and proposed restated bylaws provide that our board of directors is classified into three classes of directors. The existence of a classified board could delay a successful tender offeror from obtaining majority control of our board of directors, and the prospect of that delay might deter a potential offeror. Pursuant to Delaware law, the directors of a corporation having a classified board may be removed by the stockholders only for cause, and pursuant to our restated certificate of incorporation, by the affirmative vote of at least sixty-six and two thirds percent (66 2/3%) of the votes that all stockholders would be entitled to cast in an election of directors. In addition, stockholders will not be permitted to cumulate their votes for the election of directors.

 

   

Stockholder Action; Special Meeting of Stockholders. Our restated certificate of incorporation provides that our stockholders may not take action by written consent, but may only take action at annual or special meetings of our stockholders. Our restated certificate of incorporation further provides that special meetings of our stockholders may be called only by a majority of our board of

 

S-18


Table of Contents
 

directors, the chairman of our board of directors and our chief executive officer, or upon the request of the holders of a majority of our issued and outstanding common stock.

 

   

Advance Notice Requirements for Stockholder Proposals and Director Nominations. Our restated bylaws provide advance notice procedures for stockholders seeking to bring business before our annual meeting of stockholders, or to nominate candidates for election as directors at our annual meeting of stockholders. Our restated bylaws also specify certain requirements regarding the form and content of a stockholder’s notice. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders.

 

   

Stockholders. Our restated bylaws also specify certain requirements regarding the form and content of a stockholder’s notice. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders.

 

   

Issuance of Undesignated Preferred Stock. Under our restated certificate of incorporation, our board of directors has the authority, without further action by the stockholders, to issue up to 10,000,000 shares of undesignated preferred stock with rights and preferences, including voting rights, designated from time to time by the board of directors. The existence of authorized but unissued shares of preferred stock enables our board of directors to render more difficult or to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise.

 

   

Exclusive Forum. Our restated certificate of incorporation specifies that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for: (i) any derivative action or proceeding brought on behalf of the corporation; (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the corporation to the corporation or the corporation’s stockholders; (iii) any action asserting a claim arising pursuant to any provision of the DGCL; and (iv) any action asserting a claim governed by the internal affairs doctrine. We believe this provision benefits us by providing increased consistency in the application of Delaware law by chancellors particularly experienced in resolving corporate disputes, efficient administration of cases on a more expedited schedule relative to other forums and protection against the burdens of multi-forum litigation. However, the provision may have the effect of discouraging lawsuits against our directors and officers. The enforceability of similar choice of forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that, in connection with any applicable action brought against us, a court could find the choice of forum provisions contained in our restated certificate of incorporation to be inapplicable or unenforceable in such action.

Limitation of Liability and Indemnification

As permitted by Delaware law, we have adopted provisions in our certificate of incorporation that limit or eliminate the personal liability of our directors. Our restated certificate of incorporation limits the liability of directors to the maximum extent permitted by Delaware law. Delaware law provides that directors of a corporation will not be personally liable for monetary damages for breaches of their fiduciary duties as directors, except liability for:

 

   

any breach of the director’s duty of loyalty to us or our stockholders;

 

   

any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

 

   

any unlawful payments related to dividends or unlawful stock repurchases, redemptions or other distributions; or

 

   

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

 

S-19


Table of Contents

These limitations do not apply to liabilities arising under federal securities laws and do not affect the availability of equitable remedies, including injunctive relief or rescission. If Delaware law is amended to authorize the further elimination or limiting of a director, then the liability of our directors will be eliminated or limited to the fullest extent permitted by Delaware law as so amended.

As permitted by Delaware law, our certificate of incorporation also provides that:

 

   

we will indemnify our directors and officers to the fullest extent permitted by law;

 

   

we may indemnify our other employees and other agents to the same extent that we indemnify our officers and directors, unless otherwise determined by our board of directors; and

 

   

we will advance expenses to our directors and officers in connection with legal proceedings in connection with a legal proceeding to the fullest extent permitted by law.

The indemnification provisions contained in our certificate of incorporation are not exclusive. In addition, we have entered into indemnification agreements with each of our directors and executive officers. Each of these indemnification agreements provides, among other things, that we will indemnify such director or executive officer to the fullest extent permitted by law for claims arising in his or her capacity as a director or officer, as applicable, provided that he or she acted in good faith and in a manner that he or she reasonably believed to be in, or not opposed to, our best interests and, with respect to any criminal proceeding, had no reasonable cause to believe that his or her conduct was unlawful. Each of these indemnification agreements provide that in the event that we do not assume the defense of a claim against a director or officer, as applicable, we will be required to advance his or her expenses in connection with his or her defense, provided that he or she undertakes to repay all amounts advanced if it is ultimately determined that he or she is not entitled to be indemnified by us.

We believe that these provisions and agreements are necessary to attract and retain qualified persons as directors and officers. Insofar as indemnification for liabilities arising under the Securities Act of 1933, which we refer to as the Securities Act, may be permitted to directors, officers or persons controlling our company pursuant to the foregoing provisions, we understand that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

In addition, we maintain standard policies of insurance under which coverage is provided to our directors and officers against losses arising from claims made by reason of breach of duty or other wrongful act, and to us with respect to payments which may be made by us to such directors and officers pursuant to the above indemnification provisions or otherwise as a matter of law.

The foregoing discussion of our restated certificate of incorporation, restated bylaws, indemnification agreements and Delaware law is not intended to be exhaustive and is qualified in its entirety by such restated certificate of incorporation, restated bylaws, indemnification agreements or law.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

PLAN OF DISTRIBUTION

We have entered into a sales agreement with SVB Leerink, under which we may issue and sell from time to time up to $50,000,000.00 of our common stock through SVB Leerink as our sales agent. Sales of our common stock, if any, will be made at market prices by any method that is deemed to be an “at the market” offering as defined in Rule 415 under the Securities Act, including sales made directly on the Nasdaq Capital Market or any other trading market for our common stock. Upon delivery of a placement notice and subject to the terms and conditions of the sales agreement, we may instruct SVB Leerink not to sell common stock if the sales cannot be effected at or above the price designated by us from time to time. We or SVB Leerink may suspend the offering of common stock upon notice and subject to other conditions.

SVB Leerink will offer our common stock subject to the terms and conditions of the sales agreement on a daily basis or as otherwise agreed upon by us and SVB Leerink. We will designate the maximum amount of common stock to be sold through SVB Leerink on a daily basis or otherwise determine such maximum amount together with SVB Leerink. Subject to the terms and conditions of the sales agreement, SVB Leerink will use its commercially reasonable efforts consistent with its normal trading and sales practices to sell on our behalf all of the shares of common stock requested to be sold by us. We may instruct SVB Leerink not to sell common stock if the sales cannot be effected at or above the price designated by us in any such instruction. SVB Leerink or we may suspend the offering of our common stock being made through SVB Leerink under the sales agreement upon proper notice to the other party. SVB Leerink and we each have the right, by giving written notice as specified in the sales agreement, to terminate the sales agreement in each party’s sole discretion at any time. The offering of shares of our common stock pursuant to the sales agreement will otherwise terminate upon the termination of the sales agreement as provided therein.

The aggregate compensation payable to SVB Leerink as sales agent equals 3% of the gross sales price of the shares sold through it pursuant to the sales agreement. In addition, we have agreed to reimburse SVB Leerink up to $65,000 for certain of its legal fees and expenses in connection with the preparation of the sales agreement and establishment of the at the market offering, and $15,000 in connection with each periodic update for the offering as set forth in the sales agreement. In accordance with Financial Industry Regulatory Authority, Inc. Rule 5110, these reimbursed fees and expenses are deemed sales compensation in connection with this offering. We estimate that the total expenses of the offering payable by us, excluding commissions payable to SVB Leerink under the sales agreement, will be approximately $59,000.

The remaining sales proceeds, after deducting any expenses payable by us and any transaction fees imposed by any governmental, regulatory, or self-regulatory organization in connection with the sales, will equal our net proceeds for the sale of such common stock.

SVB Leerink will provide written confirmation to us following the close of trading on the Nasdaq Capital Market on each day in which common stock is sold through it as sales agent under the sales agreement. Each confirmation will include the number of shares of common stock sold through it as sales agent on that day, the volume weighted average price of the shares sold, the compensation payable by us to SVB Leerink, and the net proceeds to us.

We will report at least quarterly the number of shares of common stock sold through SVB Leerink under the sales agreement, the net proceeds to us and the compensation paid by us to SVB Leerink in connection with the sales of common stock.

Settlement for sales of common stock will occur, unless the parties agree otherwise, on the second business day that is also a trading day following the date on which any sales were made in return for payment of the net proceeds to us. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

Table of Contents

Under the sales agreement, we may also sell shares of common stock to SVB Leerink as principal for its own account, at a price to be agreed upon at the time of sale. If we sell shares to SVB Leerink as principal, we will enter into a separate terms agreement with SVB Leerink, and we will describe the agreement in a separate prospectus supplement or pricing supplement.

In connection with the sales of our common stock on our behalf, SVB Leerink will be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to SVB Leerink will be deemed to be underwriting commissions or discounts. We have agreed in the sales agreement to provide indemnification and contribution to SVB Leerink against certain liabilities, including liabilities under the Securities Act or the Exchange Act. As sales agent, SVB Leerink will not engage in any transaction that stabilizes our common stock.

Our common stock is listed on the Nasdaq Capital Market and trades under the symbol “FSTX.” The transfer agent of our common stock is Computershare Investor Services, 462 South 4th Street, Suite 1600, Louisville, KY 40202.

SVB Leerink and/or its affiliates have provided, and may in the future provide, various investment banking and other financial services for us for which services they have received and, may in the future receive, customary fees.

Item 15.

Indemnification of Directors and Officers

Section 102 of the General Corporation Law of the State of Delaware (the “Delaware General Corporation Law”) permits a corporation to eliminate the personal liability of directors of a corporation to the corporation or its stockholders for monetary damages for a breach of fiduciary duty as a director, except where the director breached his duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit.

Section 145 of the Delaware General Corporation Law authorizes a court to award, or a corporation’s board of directors to grant, indemnity to directors and officers in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities, including reimbursement for expenses incurred, arising under the Securities Act.

Section 145 of the Delaware General Corporation Law states:

(a) A corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that the person’s conduct was unlawful.

(b) A corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to

 

II-1


Table of Contents

procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

(c) To the extent that a present or former director or officer of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (a) and (b) of this section, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith.

(d) Any indemnification under subsections (a) and (b) of this section (unless ordered by a court) shall be made by the corporation only as authorized in the specific case upon a determination that indemnification of the present or former director, officer, employee or agent is proper in the circumstances because the person has met the applicable standard of conduct set forth in subsections (a) and (b) of this section. Such determination shall be made, with respect to a person who is a director or officer of the corporation at the time of such determination:

 

  (1)

By a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum; or

 

  (2)

By a committee of such directors designated by majority vote of such directors, even though less than a quorum; or

 

  (3)

If there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion; or

 

  (4)

By the stockholders.

(e) Expenses (including attorneys’ fees) incurred by an officer or director of the corporation in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the corporation as authorized in this section. Such expenses (including attorneys’ fees) incurred by former directors and officers or other employees and agents of the corporation or by persons serving at the request of the corporation as directors, officers, employees or agents of another corporation, partnership, joint venture, trust or other enterprise may be so paid upon such terms and conditions, if any, as the corporation deems appropriate.

(f) The indemnification and advancement of expenses provided by, or granted pursuant to, the other subsections of this section shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person’s official capacity and as to action in another capacity while holding such office. A right to indemnification or to advancement of expenses arising under a provision of the certificate of incorporation or a bylaw shall not be eliminated or impaired by an amendment to the certificate of incorporation or the bylaws after the occurrence of the act or omission that is the subject of the civil, criminal, administrative or investigative action, suit or proceeding for which indemnification or advancement of expenses is sought, unless the provision in effect at the time of such act or omission explicitly authorizes such elimination or impairment after such action or omission has occurred.

 

II-2


Table of Contents

(g) A corporation shall have power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation would have the power to indemnify such person against such liability under this section.

(h) For purposes of this section, references to “the corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under this section with respect to the resulting or surviving corporation as such person would have with respect to such constituent corporation if its separate existence had continued.

(i) For purposes of this section, references to “other enterprises” shall include employee benefit plans; references to “fines” shall include any excise taxes assessed on a person with respect to any employee benefit plan; and references to “serving at the request of the corporation” shall include any service as a director, officer, employee or agent of the corporation which imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner such person reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the corporation” as referred to in this section.

(j) The indemnification and advancement of expenses provided by, or granted pursuant to, this section shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

(k) The Court of Chancery is hereby vested with exclusive jurisdiction to hear and determine all actions for advancement of expenses or indemnification brought under this section or under any bylaw, agreement, vote of stockholders or disinterested directors, or otherwise. The Court of Chancery may summarily determine a corporation’s obligation to advance expenses (including attorneys’ fees).

As permitted by Delaware law, our amended and restated certificate of incorporation limits or eliminates the personal liability of our directors to the maximum extent permitted by Delaware law.

Our amended and restated bylaws provide for indemnification of our directors and executive officers to the maximum extent permitted by the Delaware General Corporation Law.

In addition, we have entered into indemnification agreements with each of our current directors and executive officers and we intend to enter into new indemnification agreements with certain of our current directors and each of our executive officers. These agreements will require us to indemnify these individuals to the fullest extent permitted under Delaware law against liabilities that may arise by reason of their service to us and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified. We also intend to enter into indemnification agreements with our future directors and executive officers.

We also maintain standard policies of insurance under which coverage is provided to our directors and officers against losses arising from claims made by reason of breach of duty or other wrongful act, and to us with respect to payments which may be made by us to such directors and officers pursuant to the above indemnification provisions or otherwise as a matter of law

 

II-3


Table of Contents

The above discussion of our amended and restated certificate of incorporation, our amended and restated bylaws, our indemnification agreements with our current directors and executive officers and Sections 102 and 145 of the Delaware General Corporation Law is not intended to be exhaustive and is respectively qualified in its entirety by such amended and restated certificate of incorporation, such amended and restated bylaws, such indemnification agreements and such statutes.

To the extent that our directors, officers and controlling persons are indemnified under the provisions contained in our amended and restated certificate of incorporation, Delaware law or contractual arrangements against liabilities arising under the Securities Act, we have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Undertakings

 

(a)

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 the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. 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; and

 

  (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 such information in the registration statement; provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii)

 

II-5


Table of Contents
  do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission 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, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

 

  (2)

That, for the purpose 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.

 

  (4)

That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

 

  (i)

Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

 

  (ii)

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

 

  (5)

That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

 

  (i)

Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

 

  (ii)

Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

 

  (iii)

The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

 

  (iv)

Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

 

II-6


Table of Contents
(b)

That, for purposes of determining any liability under the Securities Act:

 

  (i)

the information omitted from the form of prospectus filed as part of the registration statement in reliance upon Rule 430A and contained in the form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of the registration statement as of the time it was declared effective; and

 

  (ii)

each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

 

(c)

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 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to 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.

 

(d)

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant, 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 such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, 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.

 

(e)

The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act (“Act”) in accordance with the rules and regulations prescribed by the Commission under section 305(b)(2) of the Act
