Series X Convertible Preferred Stock

Common Stock

 

 

We are offering 5,003 shares of our Series X Convertible Preferred Stock (“Series X Preferred Stock”) and 1,200,000 shares of our common stock (and the common stock issuable from time to time upon conversion of the Series X Preferred Stock) pursuant to this prospectus supplement and the accompanying prospectus. The Series X Preferred Stock and the common stock will be issued separately. The shares of Series X Preferred Stock and common stock are being sold directly to Biotechnology Value Fund, L.P. (“BVF”) which is an existing stockholder of the Company, and certain entities affiliated with BVF, pursuant to a subscription agreement dated as of February 10, 2017.

Our common stock is listed on the NASDAQ Global Market under the symbol “XOMA.” On February 10, 2017, the last reported sale price for our common stock on the NASDAQ Global Market was $4.03 per share. There is no established public trading market for the Series X Preferred Stock, and we do not expect a market to develop. In addition, we do not intend to apply for listing of the Series X Preferred Stock on any national securities exchange or other nationally recognized trading system.

Each share of Series X Preferred Stock is convertible into 1,000 shares of our common stock at any time at the option of the holder provided that each holder will be prohibited from converting Series X Preferred Stock into our common stock if, as a result of such conversion, the holder, together with its affiliates, would own more than a pre-set conversion blocker threshold, which will initially be set at 19.99% of the total number shares of our common stock then issued and outstanding. In the event of our liquidation, dissolution or winding up, holders of our Series X Preferred Stock will participate pari passu with any distribution of proceeds to holders of our common stock. Shares of Series X Preferred Stock will generally have no voting rights, except as required by law and except that the consent of the holders of the outstanding Series X Preferred Stock will be required to amend the terms of the Series X Preferred Stock and to approve certain corporate actions.

The Series X Preferred Stock and common stock are being offered directly to investors without a placement agent or underwriter.

We are not paying underwriting discounts or commissions in connection with the offering. We estimate that the gross proceeds to us before expenses will be approximately $25,000,000. We estimate the total expenses of this offering will be approximately $110,000.

 

 

An investment in our Series X Preferred Stock and our common stock involves risks. Before making an investment decision, you should carefully review the information under “ Risk Factors ” beginning on page S-5 of this prospectus supplement and in our Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2016, which has been filed with the Securities and Exchange Commission and is incorporated by reference in this prospectus supplement and the accompanying prospectus.

PROSPECTUS SUPPLEMENT SUMMARY

The following summary highlights some of the information contained elsewhere in this prospectus supplement or the accompanying prospectus or incorporated by reference herein or therein. Because this is only a summary, however, it does not contain all of the information that may be important to you. You should carefully read this prospectus supplement and the accompanying prospectus, including the documents incorporated by reference, which are described under “Incorporation of Certain Information by Reference” in this prospectus supplement and under “Incorporation of Certain Information by Reference” and “Where You Can Find Additional Information” in the accompanying prospectus. You also should carefully consider the matters discussed in the section entitled “Risk Factors” in the accompanying prospectus and in other periodic reports incorporated herein by reference.

Company Overview

XOMA Corporation (“XOMA”), a Delaware corporation, discovers and develops innovative antibody-based therapeutics. We also seek to optimize, license and monetize our portfolio of proprietary antibodies and underlying technologies that we have invented. Our asset base includes antibodies with unique properties including several that interact at allosteric sites on a specific protein rather than the orthosteric, or active, sites. These compounds are designed to either enhance or diminish the target protein’s activity as desired. We believe allosteric-modulating antibodies may be more selective or offer a safety advantage in certain disease indications when compared to more traditional modes of action.

We have an extensive portfolio of products, programs, and technologies that are the subject of licenses we have in place with other biotech and pharmaceutical companies. There are over 25 such programs that are funded by other companies and could produce milestone payments and royalty payments in the future. An example of this is the anti-TGFb program that we licensed to Novartis in September 2015 for which we received an upfront payment of $37.0 million, potential milestone payments of up to $480.0 million, and up to double digit royalties.

In February 2017, we announced we were expanding the first-in-class 358 clinical program into two multi-dose clinical studies for patients with hypoglycemia due to Congenital Hyperinsulinism and patients with hypoglycemia post bariatric surgery. These two indications are rare conditions with very few therapeutic options. Our current clinical development focus is initially on the XOMA 358 clinical programs.

We were incorporated in Delaware in 1981 and became a Bermuda exempted company in December 1998. Effective December 31, 2011, we changed our jurisdiction of incorporation from Bermuda to Delaware and changed our name from XOMA Ltd. to XOMA Corporation.

Our principal executive offices are located at 2910 Seventh Street, Berkeley, California 94710, and we maintain a registered office located at Corporation Trust Center, 1209 Orange Street, Wilmington, Delaware 19801. Our telephone number at our principal executive offices is (510) 204-7200. Our website address is www.xoma.com. Information found on, or accessible through, our website is not a part of, and is not incorporated into, this prospectus supplement, and you should not consider it part of this prospectus supplement. Our website address is included in this document as an inactive textual reference only.

Risks Associated with Our Business

We have been and are developing numerous product candidates, and as a result have experienced significant losses. As of September 30, 2016, we had an accumulated deficit of $1.2 billion. Our product candidates are still being developed, and we do not know whether we will ever achieve sustained profitability or whether cash flow from future operations will be sufficient to meet our needs.

We have devoted most of our financial resources to research and development, including our non-clinical development activities and clinical trials. To date, we have financed our operations primarily through the sale of equity securities and debt, and collaboration and licensing arrangements. Our total debt currently exceeds our total cash and cash equivalents. The size of our future net losses will depend, in part, on the rate of future expenditures and our ability to generate revenues. We expect to continue to incur substantial expenses as we continue our research and development activities for our product candidates. If our product candidates are not successfully developed or commercialized, or if revenues are insufficient following marketing approval, we will not achieve profitability and our business may fail. Our ability to achieve profitability is dependent in large part on the success of our development programs, obtaining regulatory approval for our product candidates and licensing certain of our preclinical compounds, all of which are uncertain. Our success is also dependent on obtaining regulatory approval to market our product candidates through current and future collaborations, which may not materialize or prove to be successful.

You should read these risks before you invest in our securities.

RISK FACTORS

An investment in our common stock and Series X Preferred Stock involves a high degree of risk. Before making an investment decision, you should carefully consider the risks described below and in the section titled “Risk Factors” contained in our Quarterly Report on Form 10-Q for the period ended September 30, 2016, which are incorporated by reference in this prospectus supplement and the accompanying prospectus in their entirety, together with all of the other information included in this prospectus supplement, the accompanying prospectus, the documents incorporated by reference in this prospectus supplement and the accompanying prospectus, and in any free writing prospectus that we have authorized for use in connection with this offering. The risks described in such documents are not intended to be an all-inclusive list of the potential risks relating to an investment in our securities. Any of such risk factors could significantly and adversely affect our business, prospects, financial condition and results of operations. As a result, the trading price or value of our securities could be materially adversely affected and you may lose all or part of your investment.

Risks Related to this Offering

We may conclude that there is substantial doubt regarding our ability to continue as a going concern.

Regardless of the amount of the net proceeds that we receive from this offering, if any, we may conclude, in connection with the issuance of our consolidated financial statements for the year ended December 31, 2016, or any other subsequent period, that there is substantial doubt regarding our ability to continue as a going concern. If our independent registered public accounting firm issues a “going concern” opinion, it could impair our ability to finance our operations through the sale of equity, incurring debt, or other financing alternatives. If we fail to raise sufficient additional capital, we will not be able to completely execute our business plan. As a result, our business would be jeopardized and we may not be able to continue. If we ceased operations, it is likely that purchasers of our common stock would lose their entire investment.

Management will have broad discretion as to the use of the proceeds from this offering and may not use the proceeds effectively.

Our management will have broad discretion as to the application of the net proceeds from this offering other than the proceeds that we will use to prepay certain outstanding indebtedness, as described below in “Use of Proceeds.” Our management may use the net proceeds for corporate purposes that may not improve our financial condition or market value of our common stock. Pending use of the net proceeds, we may invest the proceeds in short-term, investment-grade, interest-bearing instruments. These investments may not yield a favorable return to our stockholders.

Future sales of substantial amounts of our common stock, or the possibility that such sales could occur, or the conversion of our preferred stock into common stock, could adversely affect the market price of our common stock.

Sales of substantial amounts of our common stock in the public market, or the perception that significant sales are likely, could adversely affect the market price of our common stock. Assuming the sale of 1,200,000 shares of common stock at an offering price of $4.03 per share (the closing price of our common stock on February 10, 2017, as reported on the NASDAQ Global Market), the number of shares of common stock offered by us in this offering is equal to approximately 19.0% of the outstanding common stock as of February 10, 2017. We cannot predict the effect that market sales of such a large number of shares would have on the market price of our common stock. Moreover, actual or anticipated downward pressure on the market price of our common stock due to actual or anticipated sales of our common stock could cause some institutions or individuals to engage in short sales of our common stock, which may itself cause the market price of our common stock to decline.

There is no public market for the Series X Preferred Stock offered in this offering.

There is no established public trading market for the Series X Preferred Stock being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply for listing of the Series X Preferred Stock on any national securities exchange or other nationally recognized trading system. Without an active market, the liquidity of the Series X Preferred Stock will be limited.

Purchasers who convert their shares of Series X Preferred Stock into common stock will incur immediate dilution.

Upon conversion of your shares of Series X Preferred Stock, you will experience immediate and substantial dilution because the per share conversion price of your shares of Series X Preferred Stock will be higher than the net tangible book value per share of the common stock outstanding immediately after this offering.

 

S-5


Table of Contents

Holders of the Series X Preferred Stock will have no rights as holders of common stock until they acquire common stock.

Until you acquire common stock upon conversion of the Series X Preferred Stock, other than the right of the convertible preferred stock to receive dividends equal to and on the same terms as dividends actually paid on shares of our common stock, you will have no rights as a holder of our common stock, including rights to vote or respond to tender offers. Upon conversion of your Series X Preferred Stock, you will be entitled to exercise the rights of a holder of common stock only as to matters for which the record date occurs after the conversion date.

Because we will not declare cash dividends on our common stock in the foreseeable future, stockholders must rely on appreciation of the value of our common stock for any return on their investment.

We have never declared or paid cash dividends on our common stock. We currently anticipate that we will retain future earnings for the development, operation and expansion of our business and will not declare or pay any cash dividends in the foreseeable future. As a result, only appreciation of the price of our common stock, if any, will provide a return to investors in this offering.

 

S-6


Table of Contents

USE OF PROCEEDS

We estimate that the net proceeds that we will receive from this offering will be approximately $24.9 million after deducting estimated expenses payable by us.

We currently intend to use the net proceeds from this offering to prepay certain outstanding indebtedness, fund the clinical development of XOMA 358, fund additional preclinical and regulatory activities for other product candidates, and for other general corporate purposes.

We currently intend to use approximately $6.8 million of the proceeds to reduce our outstanding indebtedness under the Loan and Security Agreement with Hercules Technology III, L.P., dated February 27, 2015, as amended December 21, 2016, under which we initially borrowed $20.0 million. The Hercules Term Loan has a variable interest rate that is the greater of either (i) 9.40% plus the prime rate as reported from time to time in The Wall Street Journal minus 7.25%, or (ii) 9.40% and a maturity date of September 1, 2018. In addition to the principal repayment, we may be required to pay a prepayment charge of up to 2.0% of the principal amount prepaid.

With the exception of the prepayment of indebtedness, we have not determined the amount of net proceeds from this offering that we will use specifically for any of the foregoing purposes. Pending use of the net proceeds, we intend to invest the proceeds in a variety of capital preservation instruments, including short-term, investment-grade, interest-bearing instruments.

Table of Contents

DESCRIPTION OF SECURITIES WE ARE OFFERING

Common Stock

The material terms and provisions of our common stock and each other class of our securities which qualifies or limits our common stock are described under the caption “Description of Capital Stock” starting on page 10 of the accompanying prospectus.

Series X Preferred Stock

The material terms and provisions of the Series X Preferred Stock being offered pursuant to this prospectus supplement and the accompanying prospectus are summarized below. This summary is subject to, and qualified in its entirety by, the rights, preferences and privileges of the Series X Preferred Stock set forth in the articles of amendment to our articles of incorporation to be filed as an exhibit to our Current Report on Form 8-K, which we expect to file with the Commission in connection with this offering.

General. Our certificate of incorporation authorizes our board of directors to issue up to 1,000,000 shares of our preferred stock, par value $0.05 per share, of which none are issued and outstanding.

Subject to the limitations prescribed by our certificate of incorporation, our board of directors is authorized to establish the number of shares constituting each series of preferred stock and to fix the designations, powers, preferences and rights of the shares of each of those series and the qualifications, limitations and restrictions of each of those series, all without any further vote or action by our stockholders. Our board of directors has designated 5,003 of the 1,000,000 authorized shares of preferred stock as Series X Preferred Stock. When issued, the shares of Series X Preferred Stock will be validly issued, fully paid and non-assessable.

Rank. The Series X Preferred Stock will rank:

 

    senior to any class or series of our capital stock hereafter created specifically ranking by its terms junior to the Series X Preferred Stock;

 

    on parity to our common stock;

 

    on parity to any class or series of our capital stock hereafter created specifically ranking by its terms on parity with the Series X Preferred Stock; and

 

    junior to any class or series of our capital stock hereafter created specifically ranking by its terms senior to the Series X Preferred Stock;

in each case, as to distributions of assets upon our liquidation, dissolution or winding up whether voluntarily or involuntarily.

Dividends. Holders of Series X Preferred Stock are entitled to receive dividends on shares of Series X Preferred Stock equal (on an as if converted to common stock basis) to and in the same form as dividends actually paid on our common stock or other junior securities.

Liquidation Preference. In the event of our liquidation, dissolution, or winding up, holders of our Series X Preferred Stock will participate pari passu (on an as-converted basis, without regard to any blocker provisions) with any distribution of proceeds to holders of our common stock.

Redemption. We are not obligated to redeem or repurchase any shares of Series X Preferred Stock. Shares of Series X Preferred Stock are not otherwise entitled to any redemption rights or mandatory sinking fund or analogous fund provisions.

Exchange Listing. We do not plan on making an application to list the Series X Preferred Stock on the NASDAQ Global Market, any national securities exchange or other nationally recognized trading system. We expect the common stock issuable upon conversion of the Series X Preferred Stock to be listed on the NASDAQ Global Market.

Conversion. The Series X Preferred Stock shall be convertible at the option of the holders thereof at any time after issuance into the number of registered shares of common stock determined by dividing the aggregate stated value of the Series X Preferred Stock being converted by the conversion price then in effect. The initial conversion price is $4.03 and is subject to adjustment as described

 

S-8


Table of Contents

below. No holder may request a conversion of its Series X Preferred Stock to the extent such conversion would result in the holder and its affiliates beneficially owning more than a pre-set conversion blocker threshold, which will initially be set at 19.99% of our common stock then outstanding (the “Beneficial Ownership Limitation”). The amount of beneficial ownership of a holder and its affiliates will be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations of that section.

Conversion Price Adjustment—Stock Dividends and Stock Splits. If we pay a stock dividend or otherwise make a distribution payable in common stock on our common stock or any common stock equivalents, subdivide or combine our outstanding common stock, or reclassify our common stock in such a way that we issue additional shares of our capital stock, the conversion price will be adjusted by multiplying the then-existing conversion price by a fraction, the numerator of which is the number of shares of common stock outstanding immediately before the distribution, dividend, adjustment or recapitalization and the denominator of which is the number of shares of common stock outstanding immediately after such action.

Fundamental Transaction. If we effect a “fundamental transaction” (as defined below), then upon any future conversion of the Series X Preferred Stock, the holders will have the right to receive, for each common share they would have received upon such conversion, the same kind and amount of securities, cash or property as such holder would have been entitled to receive in the fundamental transaction had it been the holder of common stock immediately prior to the fundamental transaction. The term “fundamental transaction” means any of the following:

 

    a merger or consolidation of the Company with or into another entity or any stock sale to, or other business combination in which the Company is not the surviving entity;

 

    the sale of all or substantially all of our assets in one transaction or a series of related transactions;

 

    any completed tender offer or exchange offer involving holders of common stock in which more than 50% of the common stock is converted or exchanged into other securities, cash or property, regardless of who makes such offer; or

 

    any reclassification of common stock or any compulsory share exchange by which our common stock is effectively converted into or exchanged for other securities, cash or property (but not a reverse stock split).

If the holders of common stock are given a choice as to the securities, cash or property to be received in a fundamental transaction, the holders of Series X Preferred Stock will be given the same choice on conversion of such holders’ shares.

Voting Rights. The Series X Preferred Stock shall have no voting rights, except to the extent expressly provided in our articles of incorporation or as otherwise required by law. However, so long as 2,502 shares of Series X Preferred Stock are outstanding, we may not take any of the following actions without the affirmative consent of holders of a majority of the outstanding Series X Preferred Stock:

 

    amend our articles of incorporation, bylaws or other charter documents so as to materially, specifically and adversely affect the preferences, rights, privileges of the Series X Preferred Stock;

 

    issue additional shares of Series X Preferred Stock or increase or decrease the number of authorized shares of Series X Preferred Stock;

 

    sell, assign, monetize, pledge or otherwise divest or encumber our rights under any material license agreement, joint venture or other partnership agreement to which we are a party as of the date of this offering and involving any drug or drug candidate;

 

    issue or commit to issue any other equity securities, with certain exceptions;

 

    issue any equity-based award or compensation to certain of our officers, unless the award has been unanimously approved by our compensation committee at a time when a designee appointed by the Series X Preferred holders is then serving on that committee; or

 

    enter into any agreement or understanding to take any of the actions listed above.

Anti-Takeover Effects of Our Charter Documents and Some Provisions of Delaware Law

Certificate of incorporation and bylaws.  Our certificate of incorporation authorizes our board of directors to issue up to 1,000,000 shares of preferred stock without stockholder approval and to set the rights, preferences and other designations, including voting rights, of those shares as the board of directors may determine. In addition, our bylaws require certain procedures to be followed and time periods to be met for any stockholder to propose matters to be considered at annual meetings of stockholders,

 

S-9


Table of Contents

including nominating directors for election at those meetings. Our bylaws also provide that our board of directors is able to elect a director to fill a vacancy created by the expansion of the board of directors or due to the resignation or departure of an existing board member. Provisions of Delaware law and our certificate of incorporation and bylaws could make the acquisition of our company through a tender offer, a proxy contest or other means more difficult and could make the removal of incumbent officers and directors more difficult.

We expect these provisions to discourage coercive takeover practices and inadequate takeover bids and to encourage persons seeking to acquire control of our company to first negotiate with our board of directors. We believe that the benefits provided by our ability to negotiate with the proponent of an unfriendly or unsolicited proposal outweigh the disadvantages of discouraging these proposals. We believe the negotiation of an unfriendly or unsolicited proposal could result in an improvement of its terms.

Section  203 of the Delaware General Corporation Law . We are subject to Section 203 of the DGCL, an anti-takeover law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years following the date the person became an interested stockholder, unless:

 

    prior to the date of the transaction, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

 

    the stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding (a) shares owned by persons who are directors and also officers, and (b) shares owned by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

 

    on or subsequent to the date of the transaction, the business combination is approved by the board and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66% of the outstanding voting stock which is not owned by the interested stockholder.

Generally, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. An “interested stockholder” is a person 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 a corporation’s outstanding voting securities. We expect the existence of this provision to have an anti-takeover effect with respect to transactions our board of directors does not approve in advance. We also anticipate that Section 203 may discourage attempts that might result in a premium over the market price for the shares of common stock held by stockholders.

DILUTION

If you purchase our common stock in this offering, you will experience dilution to the extent of the difference between the price per common share you pay in this offering and the net tangible book value per common share immediately after this offering. Our net tangible book value as of September 30, 2016 was approximately $(31.2) million or approximately $(5.17) per share of common stock. Net tangible book value per share represents our total tangible assets less total tangible liabilities, divided by the number of shares of common stock outstanding as of September 30, 2016.

After giving effect to the sale by us of 1,200,000 shares of our common stock in this offering at an assumed public offering price of $4.03 per share (the closing price of our common stock on February 10, 2017) and 5,003 shares of our Series X Preferred Stock at an assumed public offering price of $4,030 (excluding any shares of common stock issued upon conversion of Series X Preferred Stock), and after deducting the estimated fees and commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of September 30, 2016 would have been approximately $(6.3) million or approximately $(0.87) per share of common stock. This represents an immediate increase in net tangible book value of approximately $4.30 per share of common stock to existing stockholders and an immediate dilution of approximately $4.90 per share of common stock to new investors. The following table illustrates this per share dilution:

 

Assumed public offering price per share of common stock

      $ 4.03   

Net tangible book value per share of common stock as of September 30, 2016

   $ (5.17   

Increase in net tangible book value per share attributable to new investors purchasing shares of common stock and Series X Preferred Stock

   $ 4.30      
  

 

 

    

As adjusted net tangible book value per share of common stock as of September 30, 2016, after giving effect to this offering

      $ (0.87
     

 

 

 

Dilution per share of common stock to new investors in the offering

      $ 4.90   
     

 

 

 

Assuming the shares of Series X Preferred Stock were immediately converted, this would result in an as adjusted net tangible book value per share, after giving effect to this offering and the Preferred Stock conversion of $(0.51), which represents a dilution per share to new investors of $4.54, and an increase in net tangible book value per share to existing stockholders of $4.66.

The above discussion and table are based on 6,029,564 shares outstanding on September 30, 2016, and excludes:

 

    5,003,000 shares of common stock issuable upon conversion of the Series X Preferred Stock and common stock offered hereby;

 

    368,560 shares of common stock issuable upon the exercise of stock options outstanding, with a weighted average exercise price of $119.10 per share;

 

    1,018,000 shares of common stock issuable upon the exercise of stock options granted in February 2017, with an exercise price of $4.03 per share (subject to approval by our stockholders of a commensurate increase in the number of shares available under our 2010 Long Term Incentive and Stock Award Plan);

 

    187,910 shares of common stock issuable upon the vesting of outstanding restricted stock units;

 

    916,547 shares of common stock issuable upon the exercise of our outstanding warrants, at an exercise price of $89.47 per share; and

 

    283,794 shares of common stock reserved for future issuance under our equity incentive plans and 3,362 shares of common stock reserved for issuance under our employee stock purchase plan.

In addition, up to $74.4 million of common stock may be issued pursuant to our ATM sales agreement with Cowen and Company, LLC. To the extent that options outstanding as of September 30, 2016 have been or are exercised, or other shares are issued, investors purchasing shares in this offering could experience further dilution. To the extent that additional capital is raised through the sale of equity or convertible debt securities, including pursuant to our ATM sales agreement with Cowen and Company, LLC, the issuance of these securities could result in further dilution to our stockholders.

S-A-20


Table of Contents

ii. If, on any date, the number of authorized but unissued (and otherwise unreserved) shares of Common Stock is less than the Required Minimum on such date (such date, the “ Authorized Share Failure ”), then the Company shall promptly take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve and have available the Required Minimum as of such date. Without limiting the generality of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than 90 days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its stockholders or conduct a consent solicitation for the approval of an increase in the number of authorized shares of Common Stock to have available the Required Minimum

The BVF Nominee’s appointment shall be subject to reasonable confirmation that such nominee is not prohibited from such service pursuant to the applicable legal, regulatory and stock market requirements. For so long as the Lead Investor continues to beneficially own in excess of 19.9% of the Company’s outstanding Common Stock (with beneficial ownership to be determined without regard to conversion blockers, such as the “Beneficial Ownership Limitation” set forth in the Series X Preferred Stock Certificate of Designation (a “ Blocker ”) as of the record date for such Annual Meeting of Stockholders ): (a) the Board of Directors of the Company shall consist of no more than seven members after the date of 2017 Annual Meeting of Stockholders, and (b), the Lead Investor shall have the right (but not the obligation) to nominate a single director for inclusion in the Company’s proxy statement on Schedule 14A for use in soliciting proxies for each Annual Meeting of Stockholders after the Effective Date, but only if the BVF Nominee is not already named in such proxy statement as a director nominee put forth by the Board of Directors for reelection at such meeting.

Maximum ”) on the same terms, conditions and price provided for in the Subsequent Financing (provided that if the Purchaser is limited or chooses to be limited in its ability to purchase beyond a given level of beneficial ownership (e.g., due to applicable NASDAQ limits or due to a desire to stay below 10% beneficial ownership), then the Company shall instead offer the Purchaser the right to purchase a comparable security with a Blocker and otherwise substantially similar economic rights and interests). Notwithstanding anything in this Section  4.8 , in the event a Subsequent Financing is an offering registered under the Securities Act, the Company shall offer the Purchasers the same right to participate in such registered offering (up to its pro rata amount) only when it is lawful for the Company to do so.

ii. Subject to compliance with any applicable laws, at least three Trading Days prior to the closing of the Subsequent Financing, the Company shall deliver to the Purchasers a written notice of its intention to effect a Subsequent Financing
(“ Pre-Notice ”), which Pre-Notice shall inquire with the Purchasers whether it wishes to review the details of such proposed financing (such additional notice, a “ Subsequent Financing Notice ”). Upon the request of the Purchasers, and only upon a request by the Purchasers, for a Subsequent Financing Notice, the Company shall promptly, but no later than one Trading Day after such request, deliver a Subsequent Financing Notice to the Purchasers. The requesting Purchasers shall be deemed to have acknowledged that the Subsequent Financing Notice may contain material non-public information. Subject to compliance with any applicable laws, the Subsequent Financing Notice shall describe in reasonable detail the proposed terms of such Subsequent Financing, the amount of proceeds intended to be raised thereunder and the Person or Persons through or with whom such Subsequent Financing is proposed to be effected and shall include a term sheet or similar document relating thereto as an attachment.

iii. If a Purchaser wishes to participate in such Subsequent Financing, it must provide written notice to the Company by not later than 5:30 p.m. (Pacific Time) on the second Trading Day after the Purchasers have received the Subsequent Financing Notice, that such Purchaser is willing to participate in the Subsequent Financing and the amount of such Purchaser’s participation. If the Company receives no such notice from a given Purchaser as of such second Trading Day, that Purchaser shall be deemed to have notified the Company that it does not elect to participate and the Company may effect the Subsequent Financing on the terms and with the Persons (including any participating Purchasers) set forth in the Subsequent Financing Notice.

iv. If by 5:30 p.m. (Pacific Time) on the second Trading Day after the Purchasers have received the Subsequent Financing Notice, the Company has received written notification by one or more Purchasers of their willingness to participate in the Subsequent Financing (or to cause its designees to participate), then the Company shall effect the Subsequent Financing with such Purchaser(s) (in the amount indicated in its notification up to the Participation Maximum) and, with respect to the remaining portion of such Subsequent Financing on the terms and with the Persons set forth in the Subsequent Financing Notice, subject to compliance with any applicable laws.

v. The Company must provide the Purchasers with a second Subsequent Financing Notice, and the Purchasers will again have the right of participation set forth above in this Section 4.8, if the Subsequent Financing subject to the initial Subsequent Financing Notice is amended in any material respect or is not consummated for any reason on the terms set forth in such Subsequent Financing Notice within 30 days after the date of the initial Subsequent Financing Notice.

vi. Notwithstanding anything to the contrary in this Section  4.8 and unless otherwise agreed to by the Purchasers, the Company shall either confirm in writing to the Purchasers that the transaction with respect to the Subsequent Financing has been abandoned or shall publicly disclose its intention to issue the securities in the Subsequent Financing, in either case in such a manner such that the Purchasers will not be in possession of any material, non-public information, by the third Business Day following delivery of the Subsequent Financing Notice. If by such third Business Day, no public disclosure regarding a transaction with respect to the Subsequent Financing has been made, and no notice regarding the abandonment of such transaction has been received by the Purchasers, such transaction shall be deemed to have been abandoned and the Purchasers shall not be deemed to be in possession of any material, non-public information with respect to the Company or any of its Subsidiaries.

4.9 Equity Plan Increase . At the 2017 Annual Meeting of Stockholders, the Company will seek stockholder approval of an increase in the available pool of shares of Common Stock available for grant under the Company’s Amended and Restated 2010 Long Term Incentive and Stock Award Plan (the “ 2010 Plan ”), with the aggregate number of shares authorized for issuance under all equity plans currently or previously maintained by the Company (including the 2010 Plan) and all outstanding equity awards to equal, in total, approximately 12.5% of the total number of issued and outstanding shares of Common Stock immediately after the Closing (calculated on a pro forma basis, and assuming the conversion of all Series X Preferred Stock, without giving effect to any Blockers). No new issuances of awards shall be made under the 2010 Plan between the Effective Date and the Closing Date. Following the Closing Date, any new awards grants to the Company’s principal executive officer or principal financial officer issued under the 2010 Plan shall be made solely in accordance with the conditions set forth in Section 4(b) of the Series X Certificate of Designations.

XOMA CORPORATION

Overview

XOMA Corporation (“XOMA”), a Delaware corporation, discovers and develops innovative antibody-based therapeutics. Several of our antibodies have unique properties due to their interaction at allosteric sites on specific protein rather than the orthosteric, or active sites. The compounds are designed to either enhance or diminish the protein’s activity as desired. We believe allosteric-modulating antibodies may be more selective or offer a safety advantage in certain disease indications when compared to more traditional modes of action.

Our lead drug candidate, gevokizumab, is a proprietary potent, humanized allosteric-modulating monoclonal antibody that binds to the inflammatory cytokine interleukin-1 beta (“IL-1 beta”). We believe that by targeting IL-1 beta, gevokizumab has the potential to address the underlying inflammatory causes of a wide range of diseases that have been identified as having unmet medical needs.

Together with our development partner, Les Laboratoires Servier (“Servier”), an independent French pharmaceutical research company, we have initiated four pivotal clinical trials evaluating gevokizumab for the treatment of non-infectious intermediate, posterior or pan-uveitis (“NIU”) and Behçet’s disease uveitis. We are responsible for all of the clinical study sites in the United States, and Servier is responsible for all of the clinical study sites outside of the United States. These studies are known as the EYEGUARD™ program, which includes EYEGUARD-A (patients with active NIU), EYEGUARD-B (patients with Behçet’s disease uveitis outside of the United States), EYEGUARD-C (patients with a history of NIU currently controlled with systemic treatment), and EYEGUARD-US (patients with Behçet’s disease uveitis being conducted at study centers in the United States).

Our strategy is to pursue Behçet’s disease uveitis as our first indication for gevokizumab in the United States. Upon the successful completion of SERVIER’s EYEGUARD-B study, we intend to meet with the U.S. Food and Drug Administration (“FDA”) to review the Phase 3 EYEGUARD-B data together with the data from the two Behçet’s disease uveitis Phase 2 studies conducted independently by XOMA and Servier. We believe the seriousness of this disease and the small patient population warrant consideration for approval based upon positive data from a single pivotal study. There is significant precedence for regulatory approval based upon a single study for indications of similar seriousness in patient populations. Should EYEGUARD-B successfully demonstrate patients with Behçet’s disease uveitis receiving gevokizumab took longer to exacerbate than the placebo-treated patients during the tapering of administered steroids, we believe we will be in position to begin the Biologics License Application (“BLA”) submission process.

In addition to the EYEGUARD studies, we are evaluating gevokizumab in pyoderma gangrenosum (“PG”), a rare ulcerative skin disease that is a specific indication under the umbrella of diseases known as neutrophilic dermatosis. Patients experience painful expanding skin ulcers that have a significant impact on their quality of life. The U.S. Department of Health and Human Services’ National Institutes of Health’s Office of Rare Disease Research lists PG occurring in about one per 100,000 people. Claims data compiled

Table of Contents

over the past three years indicate the number of diagnosed PG patients in the U.S. ranges between 11,000 and 14,000 annually. Based upon what we believe are compelling data from our pilot study in patients with PG, we initiated a Phase 3 clinical program in October 2014. The PG Phase 3 program includes two double-blind, placebo-controlled clinical studies, each of which is designed to enroll 58 patients with active PG to receive gevokizumab 60 mg or placebo dosed subcutaneously once monthly, in addition to their current treatment regimen of low-dose corticosteroids and/or immunosuppressants. The primary endpoint is the complete closure of the PG target ulcer determined at Day 126 and confirmation of complete closure a minimum of two weeks later on or after Day 140.

We and Servier also have an active gevokizumab Proof-of-Concept (“POC”) development program to identify other illnesses for late-stage development.

Gevokizumab has been generally well tolerated across all of our clinical studies. The most common adverse events were headache, pain, arthralgia, urinary tract infections, upper respiratory tract infections and pneumonia, and they were comparable between gevokizumab and placebo.

Our proprietary pipeline includes classes of allosteric modulating antibodies that activate, sensitize or deactivate the insulin receptor in vivo, which we have named XOMA Metabolism or XMet. Insulin is the major hormone for lowering blood glucose levels. Abnormal increases in insulin secretion can lead to profound hypoglycemia (low blood sugar), a state that may result in significant morbidities including cerebral damage and epilepsy. In some instances, profound hypoglycemia can result in fatality. There are three programs in the XMet portfolio, XOMA 358, which is designed to deactivate the insulin receptor, XMetA, which is designed to activate the insulin receptor, and XMetS, which is designed to sensitize the insulin receptor when in an insulin resistant state. These programs are highly novel as the antibodies bind to different sites on the insulin receptor than currently marketed drugs.

XOMA 358 is a fully human monoclonal allosteric modulating antibody that binds to insulin receptors and attenuates insulin action. It is designed to negatively modulate the insulin receptor and its downstream signaling capabilities. We launched clinical development activities for XOMA 358 in October 2014, with the first patient dosed in our Phase 1 safety and tolerability study. We intend to investigate this compound as a novel treatment for non-drug-induced, endogenous hyperinsulinemic hypoglycemia (low blood glucose caused by excessive insulin produced by the body). A therapy that safely and effectively mitigates insulin-induced hypoglycemia has the potential to address a significant unmet therapeutic need for certain rare medical conditions associated with hyperinsulinism.

We intend to retain full ownership of the XOMA 358, as it aligns with our focus to develop products for diseases with significant unmet medical need and treated by the specialist prescriber. We intend to license XMetA and XMetS to a pharmaceutical company with expertise in developing and commercializing compounds for Types 1 and 2 diabetes. This portfolio of antibodies represents potential new therapeutic approaches to the treatment of diabetes and several rare diseases that have insulin involvement.

Our business is subject to numerous risks, as described under the heading “Risk Factors” contained in the applicable prospectus supplement and in any free writing prospectuses we have authorized for use in connection with a specific offering, and under similar headings in the documents that are incorporated by reference into this prospectus.

Risk Factors

Investing in our securities involves a high degree of risk. Before deciding whether to invest in our securities, you should consider carefully the risks and uncertainties described under the heading “Risk Factors” contained in the applicable prospectus supplement and any related free writing prospectus, and discussed under the section entitled “Risk Factors” contained in our most recent Annual Report on Form 10-K and in our most recent Quarterly Report on Form 10-Q, as well as any amendments thereto reflected in subsequent filings with the SEC, which are incorporated by reference into this prospectus in their entirety, together with other information in this prospectus, the documents incorporated by reference and any free writing prospectus that we may authorize for use in connection with this offering. The risks described in these documents are not the only ones we face, but those that we consider to be material. There may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could have material adverse effects on our future results. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occurs, our business, financial condition, results of operations or cash flow could be seriously harmed. This could cause the trading price of our common stock to decline, resulting in a loss of all or part of your investment. Please also read carefully the section below entitled “Forward-Looking Statements.”

Forward-Looking Statements

This prospectus, including the documents that we incorporate by reference herein, contains, and any applicable prospectus supplement or free writing prospectus including the documents we incorporate by reference therein may contain, forward-looking statements, including statements related to the anticipated size of clinical trials, the anticipated timing of initiation of clinical trials, the expected availability of clinical trial results, the sufficiency of our cash resources, the estimated costs of clinical trials and the amounts of certain revenues and certain costs in comparison to prior years, or that otherwise relate to future periods, are forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The words “believe,” “may,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “predict,” “potential” and similar expressions are intended to identify forward-looking statements. These statements are based on assumptions that may not prove accurate. Actual results could differ materially from those anticipated due to certain risks inherent in the biotechnology industry and for companies engaged in the development of new products in a regulated market. Among other things: our product candidates are still being developed, and we will require substantial funds to continue development which may not be available; we have sustained losses in the past and we expect to sustain losses in the future; we are substantially dependent on Servier for the development and commercialization of gevokizumab and for other aspects of our business; we have received negative results from certain of our clinical trials, and the pace of certain ongoing trials has not always been what was initially anticipated, and we face uncertain results of other clinical trials of our product candidates; if our therapeutic product candidates do not receive regulatory approval, neither our third-party collaborators, our contract manufacturers nor we will be able to manufacture and market them; we may not obtain orphan drug exclusivity or we may not receive the full benefit of orphan drug exclusivity even if we obtain such exclusivity; even once approved, a product may be subject to additional testing or significant marketing restrictions, its approval may be withdrawn or it may be voluntarily taken off the market; we may not be successful in commercializing our products, which could also affect our development efforts; we are subject to various state and federal healthcare related laws and regulations that may impact the commercialization of ACEON or our product candidates and could subject us to significant fines and penalties; and certain of our technologies are in-licensed from third parties, so our capabilities using them are restricted and subject to additional risks. These and other risks, including those related to current economic and financial market

Use of Proceeds

Except as described in any applicable prospectus supplement or in any free writing prospectuses we have authorized for use in connection with a specific offering, we currently intend to use the net proceeds from the sale of the securities offered by us hereunder, if any, for working capital and general corporate purposes, including research and development expenses and capital expenditures.

The amounts and timing of our use of the net proceeds from this offering will depend on a number of factors, such as the timing and progress of our research and development efforts, the timing and progress of any partnering and commercialization efforts, technological advances and the competitive environment for our products. As of the date of this prospectus, we cannot specify with certainty all of the particular uses for the net proceeds to us from the sale of the securities offered by us hereunder. Accordingly, our management will have broad discretion in the timing and application of these proceeds.

Description of Capital Stock

As of the date of this prospectus, our certificate of incorporation, as amended, authorizes us to issue 277,333,332 shares of common stock, par value $0.0075 per share, and 1,000,000 shares of preferred stock, par value $0.05 per share. As of December 31, 2014, 115,892,450 shares of common stock were outstanding and no shares of preferred stock were outstanding.

The following summary describes the material terms of our capital stock. The description of capital stock is qualified by reference to our certificate of incorporation and our bylaws.

Common Stock

Dividends and distributions. The holders of our common stock have the right to receive dividends and distributions, whether payable in cash or otherwise, as may be declared from time to time by our board of directors, from legally available funds. We have not paid cash dividends on the common stock. We currently do not intend to pay dividends and intend to retain any of our earnings for use in our business and the financing of our capital requirements for the foreseeable future. The payment of any future cash dividends on the common stock is necessarily dependent upon our earnings and financial needs, along with applicable legal and contractual restrictions.

Voting rights . Each holder of our common stock is generally entitled to one vote for each share of common stock owned of record on all matters submitted to a vote of our stockholders. Except as otherwise required by law, holders of common stock (as well as holders of any preferred stock entitled to vote with the common stockholders) will generally vote together as a single class on all matters presented to the stockholders for their vote or approval, including the election of directors. Any matter brought before the stockholders for a vote, other than the election of directors, will generally be decided by a majority of the votes cast on the matter, unless the matter is one in which an express provision of the Delaware General Corporation Law, or the DGCL, the certificate of incorporation, the bylaws, the rules or regulations of any stock exchange applicable to us, applicable law or pursuant to any regulation applicable to us or our securities requires a different vote, in which case the express provision will govern and control the decision of the matter. Directors will be elected by a plurality of the votes cast and entitled to vote generally on the election of directors. There are no cumulative voting rights with respect to the election of directors or any other matters.

No preemptive or similar rights . Holders of our common stock have no redemption rights, conversion rights or preemptive rights to purchase or subscribe for our securities.

Right to receive liquidation distributions . In the event of our liquidation, dissolution or winding-up, holders of our common stock will be entitled to share equally in the assets available for distribution after payment of all creditors and the liquidation preferences of our preferred stock (if any).

Restrictions on transfer . Neither our certificate of incorporation nor our bylaws contain any restrictions on the transfer of our common stock. However, in the case of any transfer of shares, there may be restrictions imposed by applicable securities laws or by the terms of restricted share award grants.

Other Provisions . There are no redemption provisions or sinking fund provisions applicable to our common stock.

The rights of the holders of our common stock are subject to, and may be adversely affected by, the rights of holders of shares of any preferred stock that we may designate and issue in the future.

Preferred Stock

General. Under our certificate of incorporation, our board of directors is authorized by resolution to divide the preferred stock into series and, with respect to each series, to determine the designations and the powers, preferences and rights, and the qualifications, limitations and restrictions thereof, including the dividend rights, conversion or exchange rights, voting rights, redemption rights and terms, liquidation preferences, sinking fund provisions and the number of shares constituting the series. Our board of directors can, without stockholder approval but subject to the terms of the certificate of incorporation and to any resolution of the stockholders approved by at least 75% of all issued shares entitled to vote in respect thereof, issue preferred stock with voting and other rights that could adversely affect the voting power of the holders of our common stock and which could have certain anti-takeover effects. Before we may issue any series of preferred stock, our board of directors will be required to adopt resolutions creating and designating such series of preferred stock.

The following summary of terms of our preferred stock is not complete. You should refer to the provisions of our certificate of incorporation and bylaws and the resolutions containing the terms of each class or series of the preferred stock which have been or will be filed with the SEC at or prior to the time of issuance of such class or series of preferred stock and described in the applicable prospectus supplement. The applicable prospectus supplement may also state that any of the terms set forth herein are inapplicable to such series of preferred stock, provided that the information set forth in such prospectus supplement does not constitute material changes to the information herein such that it alters the nature of the offering or the securities offered.

The Series A Preferred Stock. We have designated 210,000 shares of our preferred stock as Series A Preferred Stock. There are no shares of Series A Preferred Stock issued and outstanding. Pursuant to the rights of the Series A Preferred Stock, subject to the rights of holders of any shares of any series of preferred stock ranking prior and superior, the holders of Series A Preferred Stock are entitled to receive, when, as and if declared by our board of directors out of funds legally available for the purpose, quarterly dividends payable in cash on the first day of March, June, September and December in each year, commencing on the first dividend payment date after the first issuance of a share or fraction of a share of Series A Preferred Stock, in an amount per share equal to the greater of (a) U.S.$1.00 or (b) 66  2 3 times the aggregate per share amount of all cash dividends, plus 66  2 3 times the aggregate per share amount of all non-cash dividends or other distributions, other than a dividend payable in common stock, declared on the common stock since the immediately preceding dividend payment date, or, with respect to the first dividend payment date, since the first issuance of Series A Preferred Stock.

In addition to any other voting rights required by law, holders of Series A Preferred Stock have the right to vote on all matters submitted to a vote of our stockholders with each share of Series A Preferred Stock entitled to 66 2/3 votes. Except as otherwise provided by law, holders of Series A Preferred Stock and holders of common stock generally vote together as one class on all matters submitted to a vote of our stockholders.

Unless otherwise provided in the rights attaching to a subsequently designated series of our preferred stock, the shares of Series A Preferred Stock rank junior to any other series of preferred stock subsequently issued as to the payment of dividends and distribution of assets on liquidation, dissolution or winding-up and rank senior to the common stock. Upon any liquidation, dissolution or winding-up of us, no distributions shall be made to holders of shares ranking junior to the Series A Preferred Stock unless, prior thereto, the holders of Series A Preferred Stock shall have received an amount equal to accrued and unpaid dividends and distributions, whether or not declared, to the date of such payment, plus an amount equal to the greater of (1) U.S. $100.00 per share or (2) an aggregate amount per share equal to 66  2 3 times the aggregate amount to be distributed per share to holders of common stock or to the holders of shares ranking on parity with the Series A Preferred Stock, except distributions made ratably on the Series A Preferred Stock and all other such parity shares in proportion to the total amount to which the holders of all such shares are entitled upon such liquidation, dissolution or winding-up.

Table of Contents

If we enter into any consolidation, amalgamation, merger, combination or other transaction in which shares of common stock are exchanged for or changed into cash, other securities and/or any other property, then any shares of Series A Preferred Stock issued and outstanding shall at the same time be similarly exchanged or changed in an amount per share equal to 66  2 3 times the aggregate amount of cash, securities and/or other property, as the case may be, into which or for which each share of common stock is changed or exchanged.

The Series A Preferred Stock is not redeemable.

Preferred Stock . We will fix the designations, voting powers, preferences and rights of the preferred stock of each series we issue under this prospectus, as well as the qualifications, limitations or restrictions thereof, in the certificate of designation relating to that series. We will file as an exhibit to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of any certificate of designation that describes the terms of the series of preferred stock we are offering. We will describe in the applicable prospectus supplement the terms of the series of preferred stock being offered, including, to the extent applicable:

 

    the title and stated value;

 

    the number of shares we are offering;

 

    the liquidation preference per share;

 

    the purchase price;

 

    the dividend rate, period and payment date and method of calculation for dividends;

 

    whether dividends will be cumulative or non-cumulative and, if cumulative, the date from which dividends will accumulate;

 

    the procedures for any auction and remarketing;

 

    the provisions for a sinking fund;

 

    the provisions for redemption or repurchase, if applicable, and any restrictions on our ability to exercise those redemption and repurchase rights;

 

    any listing of the preferred stock on any securities exchange or market;

 

    whether the preferred stock will be convertible into our common stock, and, if applicable, the conversion price, or how it will be calculated, and the conversion period;

 

    whether the preferred stock will be exchangeable into debt securities, and, if applicable, the exchange price, or how it will be calculated, and the exchange period;

 

    voting rights of the preferred stock;

 

    preemptive rights;

 

    restrictions on transfer, sale or other assignment;

 

    whether interests in the preferred stock will be represented by depositary shares;

 

    a discussion of material United States federal income tax considerations applicable to the preferred stock;

 

    the relative ranking and preferences of the preferred stock as to dividend rights and rights if we liquidate, dissolve or wind up our affairs;

 

12


Table of Contents
    any limitations on the issuance of any class or series of preferred stock ranking senior to or on a parity with the series of preferred stock as to dividend rights and rights if we liquidate, dissolve or wind up our affairs; and

 

    any other specific terms, preferences, rights or limitations of, or restrictions on, the preferred stock.

If we issue shares of preferred stock under this prospectus, the shares will be fully paid and non-assessable.

The issuance of preferred stock could adversely affect the voting power of holders of common stock and reduce the likelihood that common stockholders will receive dividend payments and payments upon liquidation. The issuance could have the effect of decreasing the market price of the common stock. The issuance of preferred stock also could have the effect of delaying, deterring or preventing a change in control of us.

Outstanding Warrants

In December 2014, we issued warrants to purchase 8,097,165 shares of our common stock to select institutional investors in connection with a registered direct offering, which are immediately exercisable for a period of two years from the date of issuance at an exercise price of $7.90 per share. As of December 31, 2014, all of these warrants were outstanding.

In September 2012, we issued warrants to purchase 39,346 shares of our common stock to General Electric Capital Corporation in connection with a loan amendment, which are immediately exercisable at an exercise price of $3.54 per share, and have a five year term. As of December 31, 2014, all of these warrants were outstanding.

In March 2012, we issued warrants to purchase 14,834,577 shares of our common stock in connection with an underwritten offering, which are immediately exercisable at an exercise price of $1.76 per share and have a five-year term. As of December 31, 2014, 12,109,418 of these warrants were outstanding.

In December of 2011, we issued warrants in connection with a debt financing, which entitle the holder to purchase up to an aggregate of 263,158 unregistered shares of our common stock at an exercise price equal to $1.14 per share, are immediately exercisable and will expire on December 30, 2016. In February of 2010, we issued warrants to purchase 1,260,000 shares of our common stock in connection with an underwritten offering, which are exercisable beginning six months and one day after issuance and have a five-year term and an exercise price of $10.50 per share. As of December 31, 2014, all of the warrants issued in December of 2011 and February of 2010 were outstanding.

Anti-Takeover Effects of Our Charter Documents and Some Provisions of Delaware Law

Certificate of incorporation and bylaws. Our certificate of incorporation authorizes our board of directors to issue up to 1,000,000 shares of preferred stock without stockholder approval and to set the rights, preferences and other designations, including voting rights, of those shares as the board of directors may determine. In addition, our bylaws require certain procedures to be followed and time periods to be met for any stockholder to propose matters to be considered at annual meetings of stockholders, including nominating directors for election at those meetings. Our bylaws also provide that our board of directors is able to elect a director to fill a vacancy created by the expansion of the board of directors or due to the resignation or departure of an existing board member. Provisions of Delaware law and our certificate of incorporation and bylaws could make the acquisition of our company through a tender offer, a proxy contest or other means more difficult and could make the removal of incumbent officers and directors more difficult.

Table of Contents

We expect these provisions to discourage coercive takeover practices and inadequate takeover bids and to encourage persons seeking to acquire control of our company to first negotiate with our board of directors. We believe that the benefits provided by our ability to negotiate with the proponent of an unfriendly or unsolicited proposal outweigh the disadvantages of discouraging these proposals. We believe the negotiation of an unfriendly or unsolicited proposal could result in an improvement of its terms.

Section 203 of the Delaware General Corporation Law . We are subject to Section 203 of the DGCL, an anti-takeover law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years following the date the person became an interested stockholder, unless:

 

    prior to the date of the transaction, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

 

    the stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding (a) shares owned by persons who are directors and also officers, and (b) shares owned by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

 

    on or subsequent to the date of the transaction, the business combination is approved by the board and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66% of the outstanding voting stock which is not owned by the interested stockholder.

Generally, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. An “interested stockholder” is a person 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 a corporation’s outstanding voting securities. We expect the existence of this provision to have an anti-takeover effect with respect to transactions our board of directors does not approve in advance. We also anticipate that Section 203 may discourage attempts that might result in a premium over the market price for the shares of common stock held by stockholders.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Wells Fargo Shareowner Services.

Listing on the NASDAQ Global Market

Our common stock is listed on the NASDAQ Global Market under the symbol “XOMA.”

Description of Debt Securities

We may issue debt securities from time to time, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. While the terms we have summarized below will apply generally to any debt securities that we may offer under this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the applicable prospectus supplement. The terms of any debt securities offered under a prospectus supplement may differ from the terms described below. Unless the context requires otherwise, whenever we refer to the indenture, we also are referring to any supplemental indentures that specify the terms of a particular series of debt securities.

We will issue the debt securities under the indenture that we will enter into with the trustee named in the indenture. The indenture will be qualified under the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act. We have filed the form of indenture as an exhibit to the registration statement of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that we file with the SEC.

The following summary of material provisions of the debt securities and the indenture is subject to, and qualified in its entirety by reference to, all of the provisions of the indenture applicable to a particular series of debt securities. We urge you to read the applicable prospectus supplements and any related free writing prospectuses related to the debt securities that we may offer under this prospectus, as well as the complete indenture that contains the terms of the debt securities.

General

The indenture does not limit the amount of debt securities that we may issue. It provides that we may issue debt securities up to the principal amount that we may authorize and may be in any currency or currency unit that we may designate. Except for the limitations on consolidation, merger and sale of all or substantially all of our assets contained in the indenture, the terms of the indenture do not contain any covenants or other provisions designed to give holders of any debt securities protection against changes in our operations, financial condition or transactions involving us.

We may issue the debt securities issued under the indenture as “discount securities,” which means they may be sold at a discount below their stated principal amount. These debt securities, as well as other debt securities that are not issued at a discount, may be issued with “original issue discount,” or OID, for U.S. federal income tax purposes because of interest payment and other characteristics or terms of the debt securities. Material U.S. federal income tax considerations applicable to debt securities issued with OID will be described in more detail in any applicable prospectus supplement.

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

 

    the title of the series of debt securities;

 

    any limit upon the aggregate principal amount that may be issued;

 

    the maturity date or dates;

Conversion or Exchange Rights

We will set forth in the applicable prospectus supplement the terms 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 settlement upon conversion or exchange and 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

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the indenture will not contain any covenant that restricts our ability to merge or consolidate, or sell, convey, transfer or otherwise dispose of our assets as an entirety or substantially as an entirety. However, any successor to or acquirer of such assets (other than a subsidiary of ours) must assume all of our obligations under the indenture or the debt securities, as appropriate.

Events of Default under the Indenture

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the following are events of default under the indenture with respect to any series of debt securities that we may issue:

 

    if we fail to pay any installment of interest on any series of debt securities, as and when the same shall become due and payable, and such default continues for a period of 90 days; provided, however, that a valid extension of an interest payment period by us in accordance with the terms of any indenture supplemental thereto shall not constitute a default in the payment of interest for this purpose;

 

    if we fail to pay the principal of, or premium, if any, on any series of debt securities as and when the same shall become due and payable whether at maturity, upon redemption, by declaration or otherwise, or in any payment required by any sinking or analogous fund established with respect to such series; provided, however, that a valid extension of the maturity of such debt securities in accordance with the terms of any indenture supplemental thereto shall not constitute a default in the payment of principal or premium, if any;

 

    if we fail to observe or perform any other covenant or agreement contained in the debt securities or the indenture, other than a covenant specifically relating to another series of debt securities, and our failure continues for 90 days after we receive written notice of such failure, requiring the same to be remedied and stating that such is a notice of default thereunder, from the trustee or holders of at least 25% in aggregate principal amount of the outstanding debt securities of the applicable series; and

 

    if specified events of bankruptcy, insolvency or reorganization occur.

If an event of default with respect to debt securities of any series occurs and is continuing, other than an event of default specified in the last bullet point above, the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series, by notice to us in writing, and to the trustee if notice is given by such holders, may declare the unpaid principal of, premium, if any, and accrued interest, if any, due and payable immediately. If an event of default specified in the last bullet point above occurs with respect to us, the principal amount of and accrued interest, if any, of each issue of debt securities then outstanding shall be due and payable without any notice or other action on the part of the trustee or any holder.

The holders of a majority in principal amount of the outstanding debt securities of an affected series may waive any default or event of default with respect to the series and its consequences, except defaults or events of default regarding payment of principal, premium, if any, or interest, unless we have cured the default or event of default in accordance with the indenture. Any waiver shall cure the default or event of default.

Subject to the terms of the indenture, if an event of default under an indenture shall occur and be continuing, the 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 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 trustee, or exercising any trust or power conferred on the 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

 

18


Table of Contents
    subject to its duties under the Trust Indenture Act, the 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 have the right to institute a proceeding under the indenture or to appoint a receiver or trustee, or to seek other remedies only if:

 

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

 

    the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have made written request,

 

    such holders have offered to the trustee indemnity satisfactory to it against the costs, expenses and liabilities to be incurred by the trustee in compliance with the request; and

 

    the 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 other conflicting directions within 90 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 trustee regarding our compliance with specified covenants in the indenture.

Modification of Indenture; Waiver

We and the trustee may change an indenture without the consent of any holders with respect to specific matters:

 

    to cure any ambiguity, defect or inconsistency in the indenture or in the debt securities of any series;

 

    to comply with the provisions described above under “Description of Debt Securities—Consolidation, Merger or Sale;”

 

    to provide for uncertificated debt securities in addition to or in place of certificated debt securities;

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 specified obligations, including obligations to:

 

    provide for payment;

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

    appoint any successor trustee.

In order to exercise our rights to be discharged, we must deposit with the trustee money or government obligations sufficient to pay all the principal of, any 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 provide otherwise in the applicable prospectus supplement, in denominations of $1,000 and any integral multiple thereof. The indenture provides 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 DTC, or another depositary named by us and identified in the applicable prospectus supplement with respect to that series. To the extent the debt securities of a series are issued in global form and as book-entry, a description of terms relating to any book-entry securities will be set forth in the applicable prospectus supplement.

At the option of the holder, subject to the terms of the indenture 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 indenture 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, we will impose 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

 

21


Table of Contents
    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 Trustee

The trustee, other than during the occurrence and continuance of an event of default under an 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 trustee must use the 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 trustee is under no obligation to exercise any of the powers given it by the indenture 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, we will make interest payments by check that we will mail to the holder or by wire transfer to certain holders. Unless we otherwise indicate in the applicable prospectus supplement, we will designate the corporate trust office of the trustee 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 trustee for the payment of the principal of or any premium or interest on any debt securities that 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 debt security thereafter may look only to us for payment thereof.

Governing Law

The indenture and the debt securities will be governed by and construed in accordance with the internal laws of the State of New York, except to the extent that the Trust Indenture Act of 1939 is applicable.

Description of Warrants

We may issue warrants for the purchase of common stock, preferred stock and/or debt securities in one or more series. We may issue warrants independently or together with common stock, preferred stock and/or debt securities, and the warrants may be attached to or separate from these securities. While the terms summarized below will apply generally to any warrants that we may offer, we will describe the particular terms of any series of warrants in more detail in the applicable prospectus supplement. The terms of any warrants offered under a prospectus supplement may differ from the terms described below.

Warrants issued under this prospectus may be issued under warrant agreements which we will enter into with a warrant agent to be selected by us. We use the term “warrant agreement” to refer to any of these warrant agreements. We use the term “warrant agent” to refer to the warrant agent under any of these warrant agreements. The warrant agent will act solely as an agent of ours in connection with the warrants and will not act as an agent for the holders or beneficial owners of the warrants.

The following summaries of material provisions of the warrants and the warrant agreements are subject to, and qualified in their entirety by reference to, all the provisions of the warrant agreement applicable to a particular series of warrants. We urge you to read the applicable prospectus supplements or free writing prospectus related to the warrants that we sell under this prospectus, as well as the complete warrant agreements that contain the terms of the warrants.

General

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

 

    the offering price and aggregate number of warrants offered;

 

    the currency for which the warrants may be purchased;

 

    the designation and terms of the securities with which the warrants are issued and the number of warrants issued with each such security or each principal amount of such security;

 

    the date on and after which the warrants and the related securities will be separately transferable;

 

    in the case of warrants to purchase debt securities, the principal amount of debt securities purchasable upon exercise of one warrant and the price at, and currency in which, this principal amount of debt securities may be purchased upon such exercise;

 

    in the case of warrants to purchase common stock or preferred stock, the number of shares of common stock or preferred stock, as the case may be, purchasable upon the exercise of one warrant and the price at which these shares may be purchased upon such exercise;

 

    the effect of any merger, consolidation, sale or other disposition of our business on the warrant agreements and the warrants;

 

    the terms of any rights to redeem or call the warrants;

 

    any provisions for changes to or adjustments in the exercise price or number of securities issuable upon exercise of the warrants;

 

    the dates on which the right to exercise the warrants will commence and expire;

 

    the manner in which the warrant agreements and warrants may be modified;

 

    a discussion of material United States federal income tax consequences of holding or exercising the warrants;

 

23


Table of Contents
    the terms of the securities issuable upon exercise of the warrants; and

 

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

Before exercising their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including:

 

    in the case of warrants to purchase debt securities, the right to receive payments of principal of, or premium, if any, or interest on, the debt securities purchasable upon exercise or to enforce covenants in the applicable indenture; or

 

    in the case of warrants to purchase common stock or preferred stock, the right to receive dividends, if any, or, payments upon our liquidation, dissolution or winding up or to exercise voting rights, if any.

Exercise of Warrants

Each warrant will entitle the holder to purchase the securities that we specify in the applicable prospectus supplement at the exercise price that we describe in the applicable prospectus supplement. Unless we otherwise specify in the applicable prospectus supplement, holders of the warrants may exercise the warrants at any time up to the specified time on the expiration date that we set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

Holders of the warrants may exercise the warrants by delivering the warrant or warrant certificate representing the warrants to be exercised together with specified information, and paying the required amount to the warrant agent, if applicable, in immediately available funds, as provided in the applicable prospectus supplement. We will set forth on the reverse side of any warrant certificate and in the applicable prospectus supplement the information that the holder of the warrant will be required to deliver to any warrant agent.

Upon receipt of the required payment and any warrant certificate properly completed and duly executed at the corporate trust office of any warrant agent or any other office indicated in the applicable prospectus supplement, we will issue and deliver the securities purchasable upon such exercise. If fewer than all of the warrants represented by a warrant certificate are exercised, then we will issue a new warrant certificate for the remaining amount of warrants. If we so indicate in the applicable prospectus supplement, holders of the warrants may surrender securities as all or part of the exercise price for warrants.

Governing Law

Unless we provide otherwise in the applicable prospectus supplement, the warrants and warrant agreements will be governed by and construed in accordance with the laws of the State of New York.

Enforceability of Rights by Holders of Warrants

Any warrant agent will act solely as our agent under the applicable warrant agreement and will not assume any obligation or relationship of agency or trust with any holder of any warrant. A single bank or trust company may act as warrant agent for more than one issue of warrants. A warrant agent will have no duty or responsibility in case of any default by us under the applicable warrant agreement or warrant, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a warrant may, without the consent of any related warrant agent or the holder of any other warrant, enforce by appropriate legal action its right to exercise, and receive the securities purchasable upon exercise of, its warrants.

Legal Ownership of Securities

We can issue securities in registered form or in the form of one or more global securities. We describe global securities in greater detail below. We refer to those persons who have securities registered in their own names on the books that we or any applicable trustee, depositary or warrant agent maintain for this purpose as the “holders” of those securities. These persons are the legal holders of the securities. We refer to those persons who, indirectly through others, own beneficial interests in securities that are not registered in their own names, as “indirect holders” of those securities. As we discuss below, indirect holders are not legal holders, and investors in securities issued in book-entry form or in street name will be indirect holders.

Book-Entry Holders

We may issue securities in book-entry form only, as we will specify in the applicable prospectus supplement. This means securities may be represented by one or more global securities registered in the name of a financial institution that holds them as depositary on behalf of other financial institutions that participate in the depositary’s book-entry system. These participating institutions, which are referred to as participants, in turn, hold beneficial interests in the securities on behalf of themselves or their customers.

Only the person in whose name a security is registered is recognized as the holder of that security. Securities issued in global form will be registered in the name of the depositary or its participants. Consequently, for securities issued in global form, we will recognize only the depositary as the holder of the securities, and we will make all payments on the securities to the depositary. The depositary passes along the payments it receives to its participants, which in turn pass the payments along to their customers who are the beneficial owners. The depositary and its participants do so under agreements they have made with one another or with their customers; they are not obligated to do so under the terms of the securities.

As a result, investors in a book-entry security will not own securities directly. Instead, they will own beneficial interests in a global security, through a bank, broker or other financial institution that participates in the depositary’s book-entry system or holds an interest through a participant. As long as the securities are issued in global form, investors will be indirect holders, and not holders, of the securities.

Street Name Holders

We may terminate a global security or issue securities in non-global form. In these cases, investors may choose to hold their securities in their own names or in “street name.” Securities held by an investor in street name would be registered in the name of a bank, broker or other financial institution that the investor chooses, and the investor would hold only a beneficial interest in those securities through an account he or she maintains at that institution.

For securities held in street name, we will recognize only the intermediary banks, brokers and other financial institutions in whose names the securities are registered as the holders of those securities, and we will make all payments on those securities to them. These institutions pass along the payments they receive to their customers who are the beneficial owners, but only because they agree to do so in their customer agreements or because they are legally required to do so. Investors who hold securities in street name will be indirect holders, not holders, of those securities.

Legal Holders

Our obligations, as well as the obligations of any applicable trustee and of any third parties employed by us or a trustee, run only to the legal holders of the securities. We do not have obligations to investors who hold beneficial interests in global securities, in street name or by any other indirect means. This will be the case whether an investor chooses to be an indirect holder of a security or has no choice because we are issuing the securities only in global form.

 

25


Table of Contents

For example, once we make a payment or give a notice to the holder, we have no further responsibility for the payment or notice even if that holder is required, under agreements with depositary participants or customers or by law, to pass it along to the indirect holders but does not do so. Similarly, we may want to obtain the approval of the holders to amend an indenture, to relieve us of the consequences of a default or of our obligation to comply with a particular provision of the indenture or for other purposes. In such an event, we would seek approval only from the holders, and not the indirect holders, of the securities. Whether and how the holders contact the indirect holders is up to the holders.

 

26


Table of Contents

Special Considerations for Indirect Holders

If you hold securities through a bank, broker or other financial institution, either in book-entry form or in street name, you should check with your own institution to find out:

 

    how it handles securities payments and notices;

 

    whether it imposes fees or charges;

 

    how it would handle a request for the holders’ consent, if ever required;

 

    whether and how you can instruct it to send you securities registered in your own name so you can be a holder, if that is permitted in the future;

 

    how it would exercise rights under the securities if there were a default or other event triggering the need for holders to act to protect their interests; and

 

    if the securities are in book-entry form, how the depositary’s rules and procedures will affect these matters.

Global Securities

A global security is a security that represents one or any other number of individual securities held by a depositary. Generally, all securities represented by the same global securities will have the same terms.

Each security issued in book-entry form will be represented by a global security that we deposit with and register in the name of a financial institution or its nominee that we select. The financial institution that we select for this purpose is called the depositary. Unless we specify otherwise in the applicable prospectus supplement, DTC will be the depositary for all securities issued in book-entry form.

A global security may not be transferred to or registered in the name of anyone other than the depositary, its nominee or a successor depositary, unless special termination situations arise. We describe those situations below under “Special Situations When a Global Security Will Be Terminated.” As a result of these arrangements, the depositary, or its nominee, will be the sole registered owner and holder of all securities represented by a global security, and investors will be permitted to own only beneficial interests in a global security. Beneficial interests must be held by means of an account with a broker, bank or other financial institution that in turn has an account with the depositary or with another institution that does. Thus, an investor whose security is represented by a global security will not be a holder of the security, but only an indirect holder of a beneficial interest in the global security.

If the prospectus supplement for a particular security indicates that the security will be issued in global form only, then the security will be represented by a global security at all times unless and until the global security is terminated. If termination occurs, we may issue the securities through another book-entry clearing system or decide that the securities may no longer be held through any book-entry clearing system.

Special Considerations for Global Securities

The rights of an indirect holder relating to a global security will be governed by the account rules of the investor’s financial institution and of the depositary, as well as general laws relating to securities transfers. We do not recognize an indirect holder as a holder of securities and instead deal only with the depositary that holds the global security.

If securities are issued only in the form of a global security, an investor should be aware of the following:

 

27


Table of Contents
    an investor cannot cause the securities to be registered in his or her name, and cannot obtain non-global certificates for his or her interest in the securities, except in the special situations we describe below;

 

    an investor will be an indirect holder and must look to his or her own bank, broker or other financial institution for payments on the securities and protection of his or her legal rights relating to the securities, as we describe above;

 

    an investor may not be able to sell interests in the securities to some insurance companies and to other institutions that are required by law to own their securities in non-book-entry form;

 

    an investor may not be able to pledge his or her interest in a global security in circumstances where certificates representing the securities must be delivered to the lender or other beneficiary of the pledge in order for the pledge to be effective;

 

    the depositary’s policies, which may change from time to time, will govern payments, transfers, exchanges and other matters relating to an investor’s interest in a global security;

 

    we and any applicable trustee have no responsibility for any aspect of the depositary’s actions or for its records of ownership interests in a global security, nor do we or any applicable trustee supervise the depositary in any way;

 

    the depositary may, and we understand that DTC will, require that those who purchase and sell interests in a global security within its book-entry system use immediately available funds, and your bank, broker or other financial institution may require you to do so as well; and

 

    financial institutions that participate in the depositary’s book-entry system, and through which an investor holds its interest in a global security, may also have their own policies affecting payments, notices and other matters relating to the securities.

There may be more than one financial intermediary in the chain of ownership for an investor. We do not monitor and are not responsible for the actions of any of those intermediaries.

Special Situations When a Global Security Will Be Terminated

In a few special situations described below, the global security will terminate and interests in it will be exchanged for physical certificates representing those interests. After that exchange, the choice of whether to hold securities directly or in street name will be up to the investor. Investors must consult their own banks, brokers or other financial institutions to find out how to have their interests in securities transferred to their own name, so that they will be direct holders. We have described the rights of holders and street name investors above.

Unless we provide otherwise in the applicable prospectus supplement, the global security will terminate when the following special situations occur:

 

    if the depositary notifies us that it is unwilling, unable or no longer qualified to continue as depositary for that global security and we do not appoint another institution to act as depositary within 90 days;

 

    if we notify any applicable trustee that we wish to terminate that global security; or

 

    if an event of default has occurred with regard to securities represented by that global security and has not been cured or waived.

The prospectus supplement may also list additional situations for terminating a global security that would apply only to the particular series of securities covered by the applicable prospectus supplement. When a global security terminates, the depositary, and not we or any applicable trustee, is responsible for deciding the names of the institutions that will be the initial direct holders.

Plan of Distribution

We may sell our securities covered by this prospectus in any of three ways (or in any combination):

 

    to or through underwriters or dealers;

 

    directly to one or more purchasers; or

 

    through agents.

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;

 

    at market prices prevailing at the time of sale;

 

    at prices related to the prevailing market prices; or

 

    at negotiated prices.

Each time we offer and sell securities covered by this prospectus, we will provide a prospectus supplement or supplements that will describe the method of distribution and set forth the terms of the offering, including:

 

    the name or names of any underwriters, dealers or agents;

 

    the amounts of securities underwritten or purchased by each of them;

 

    the purchase price of securities and the proceeds we will receive from the sale;

 

    any over-allotment options under which underwriters may purchase additional securities from us;

 

    any underwriting discounts or commissions or agency fees and other items constituting underwriters’ or agents’ compensation;

 

    the public offering price of the securities;

 

    any discounts, commissions or concessions allowed or reallowed or paid to dealers; and

 

    any securities exchange or market on which the securities may be listed.

Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time. We may determine the price or other terms of the securities offered under this prospectus by use of an electronic auction. We will describe how any auction will determine the price or any other terms, how potential investors may participate in the auction and the nature of the obligations of the underwriter, dealer or agent in the applicable prospectus supplement.

Underwriters or dealers may offer and sell the offered securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. If underwriters or dealers are used in the sale of any securities, the securities will be acquired by the underwriters or dealers for their own account and may be resold from time to time in one or more transactions described above. The securities may be either offered to the public through underwriting syndicates represented by managing underwriters, or directly by underwriters or dealers. Generally, the underwriters’ or dealers’ obligations to purchase the securities will be subject to certain conditions precedent. The underwriters or dealers will be obligated to purchase all of the securities if they purchase any of the securities, unless otherwise specified in the prospectus supplement. We may use underwriters with whom we have a material relationship. We will describe the nature of any such relationship in the prospectus supplement, naming the underwriter.

 

29


Table of Contents

We may sell the securities through agents from time to time. The prospectus supplement will name any agent involved in the offer or sale of the securities and any commissions we pay to them. Generally, any agent will be acting on a best efforts basis for the period of its appointment. We may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase the securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we pay for solicitation of these contracts.

Agents, dealers and underwriters may be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which the agents, dealers or underwriters may be required to make in respect thereof. Agents, dealers and underwriters may be customers of, engage in transactions with, or perform services for us in the ordinary course of business.

All securities we may offer, other than common stock, will be new issues of securities with no established trading market. Any underwriters may make a market in these securities, but will not be obligated to do so and may discontinue any market making at any time without notice. We cannot guarantee the liquidity of the trading markets for any securities.

Any underwriter may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with Regulation M under the Securities Exchange Act of 1934, as amended. Overallotment involves sales in excess of the offering size, which create a short position. This short sales position may involve either “covered” short sales or “naked” short sales. Covered short sales are short sales made in an amount not greater than the underwriters’ over-allotment option to purchase additional securities in this offering described above. The underwriters may close out any covered short position either by exercising their over-allotment option or by purchasing securities in the open market. To determine how they will close the covered short position, the underwriters will consider, among other things, the price of securities available for purchase in the open market, as compared to the price at which they may purchase securities through the over-allotment option. Naked short sales are short sales in excess of the over-allotment option. The underwriters must close out any naked short position by purchasing securities in the open market. A naked short position is more likely to be created if the underwriters are concerned that, in the open market after pricing, there may be downward pressure on the price of the securities that could adversely affect investors who purchase securities in this offering. Stabilizing transactions permit bids to purchase the underlying security for the purpose of fixing the price of the security so long as the stabilizing bids do not exceed a specified maximum. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions.

Any underwriters who are qualified market makers on the NASDAQ Global Market may engage in passive market making transactions in our common stock, preferred stock, warrants and debt securities, as applicable, on the NASDAQ Global Market in accordance with Rule 103 of Regulation M, during the business day prior to the pricing of the offering, before the commencement of offers or sales of the securities. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker’s bid, however, the passive market maker’s bid must then be lowered when certain purchase limits are exceeded.

Table of Contents

In compliance with guidelines of the Financial Industry Regulatory Authority, or FINRA, the maximum consideration or discount to be received by any FINRA member or independent broker dealer may not exceed 8% of the aggregate amount of the securities offered pursuant to this prospectus and any applicable prospectus supplement.

Similar to other purchase transactions, an underwriter’s purchase to cover the syndicate short sales or to stabilize the market price of our securities may have the effect of raising or maintaining the market price of our securities or preventing or mitigating a decline in the market price of our securities. As a result, the price of our securities may be higher than the price that might otherwise exist in the open market. The imposition of a penalty bid might also have an effect on the price of the securities if it discourages resales of the securities.

Neither we nor the underwriters make any representation or prediction as to the effect that the transactions described above may have on the price of the securities. If such transactions are commenced, they may be discontinued without notice at any time.

The validity of the securities being offered hereby will be passed upon for us by Cooley LLP, Palo Alto, California.
