CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, the accompanying prospectus supplement is accurate as of any date other thanand the dates on the front of such documents. 2 MIM CORPORATION We are a pharmacy benefit management, specialty pharmaceutical and fulfillment/e-commerce organization that partners with healthcare providers and sponsors to control prescription drug costs. Our pharmacy benefit products and services use clinically sound guidelines to ensure cost control and quality care. Our specialty pharmaceutical division specializes in serving the chronically ill afflicted with life threatening diseases and genetic impairments. Our fulfillment and e-commerce pharmacy specializes in serving individuals that require long-term maintenance medications. Our online pharmacy, www.MIMRx.com, develops private label websites to offer affinity groups and healthcare providers innovative and customized health information services and products on the Internet for the benefit of their members. We are incorporated under the laws of the State of Delaware. Our principal executive offices are located at 100 Clearbrook Road, Elmsford, New York 10523, and our telephone number is (914) 460-1600. RISK FACTORS You should carefully consider the following factors and other information included ordocuments incorporated by reference in this prospectus before deciding to invest in shares of common stock. We face substantial competition in our industries. The pharmacy benefit management industry, which we refer to as the PBM industry, the prescription mail serviceherein and the specialty pharmaceutical businesses are highly competitive and many of our current and potential competitors have considerably greater financial, technical, marketing and other resources than we do. The PBM business includes a number of large, well-capitalized companies with nationwide operations and many smaller organizations typically operating on a local or regional basis. One of the larger organizations is owned by or otherwise related to a brand name drug manufacturer andtherein may have significant influence on the distribution of pharmaceuticals. We also compete with several national and regional companies that primarily provide therapeutic pharmaceutical services to the chronically ill and genetically impaired, many of which also have substantial financial resources. Some of these competitors have been in the specialty pharmaceutical industry considerably longer than we have and have secured long-term supply or distribution arrangements for prescription pharmaceuticals necessary to treat certain chronic disease states on price terms substantially more favorable than the terms currently available to us. As a result of such advantageous pricing, we may be unable to compete with these companies on particular prescription products or in particular disease states. Any change in our relationship with managed care organizations providing health and prescription benefits under Tennessee's state health program could reduce our profitability. Historically, a majority of our revenues have been derived from providing PBM services in the state of Tennessee to managed care organizations, or MCOs, participating in Tennessee's TennCare (R) program. The TennCare (R) program operates under a demonstration waiver from the United States Health Care Financing Agency, which is due to expire on 3 December 31, 2001. We provide our ongoing service to those MCOs under this demonstration waiver program. If the waiver is not renewed, or we are not chosen to continue to provide pharmacy benefits to enrollees of a successor program, then the failure to provide such services would have a material adverse effect on our financial position and results of operations. The ongoing funding for the TennCare (R) program has been the subject of significant discussion at various governmental levels since its inception. Should the funding sources for the TennCare (R) program change significantly, our ability to serve those customers could be impacted and would have a material adverse effect on our financial position and results of operations. Increases in the price of pharmaceuticals may reduce our revenues. Under capitated arrangements, we are responsible for increases in prescription costs, which adversely affects our gross profits. In such instances, we may be required to increase capitated contract rates on new contracts and upon renewal of existing capitated contracts. However, there can be no assurance that we will be successful in obtaining these rate increases. If we lose relationships with one or more key pharmaceutical manufacturers or if the payments we receive from pharmaceutical manufacturers decline, our business, profitability and growth prospects could suffer. We have contractual relationships with numerous pharmaceutical manufacturers that pay us rebate payments based on use of selected drugs by health plan members, as well as fees for other programs and services. We believe our business, profitability and growth prospects could suffer if: o we lose relationships with one or more key pharmaceutical manufacturers; o rebates decline due to our failure to meet market share or other thresholds; o legal restrictions are imposed on the ability of pharmaceutical manufacturers to offer formulary rebates or purchase our programs or services; or o pharmaceutical manufacturers choose not to offer formulary rebates or purchase our programs or services. Over the next few years, as patents expire covering many brand name drugs that currently have substantial market share, generic products will be introduced that may substantially reduce the market share of the brand name drugs. Historically, manufacturers of generic drugs have not offered formulary rebates on their drugs. If the use of newly-approved, brand name drugs added to our formulary, which is the list of preferred prescription drugs covered by a health plan, does not offset any decline in use of brand name drugs whose patents expire, our profitability could be reduced. If we lose pharmacy network affiliations, our business, profitability and growth prospects could suffer. Our contracts with retail pharmacies, which are non-exclusive, are generally terminable by either party on short notice. If one or more of the top pharmacy chains elects to terminate its relationship with us or if we are only able to continue our relationship on terms less favorable to us, our members' access to retail pharmacies and our business could suffer. In addition, some large retail pharmacy chains either own or have strategic alliances with PBMs or could attempt to acquire or enter into 4 these kinds of relationships with PBMs in the future. Ownership of, or alliances with, PBMs by retail pharmacy chains could have a material adverse effect on our relationships with these retail pharmacy chains and on our business, profitability and growth prospects. We are subject to heightened federal regulatory scrutiny, which could result in sanctions or penalties. As a participant in the healthcare industry, our operations and relationships are subject to extensive federal and state laws and regulations and enforcement by federal and state governmental agencies. There are significant uncertainties regarding the application of many of these legal requirements to our business, and we cannot provide any assurance that a regulatory agency charged with enforcement of any of these laws or regulations will not interpret them differently or, if there is an enforcement action brought against us, that our interpretation would prevail. In addition, there are numerous proposed health care laws and regulations at the federal and state levels, many of which could materially affect our ability to conduct our business or adversely affect our results of operations. We are unable to predict what additional federal or state legislation or regulatory initiatives may be enacted in the future relating to our business or the health care industry in general, or what effect any such legislation or regulations might have on us. Under a corporate integrity agreement we entered into with the Office of Inspector General or OIG, within the U.S. Department of Health and Human Services or HHS, we are subject to increased oversight by the OIG. Should the oversight procedures reveal credible evidence of any violation of federal law, we are required to report such potential violations to the OIG and the U.S. Department of Justice. We are therefore subject to increased regulatory scrutiny and, if we commit legal or regulatory violations, we may be subject to an increased risk of sanctions or penalties, including exclusion from participation in the Medicare or Medicaid programs. Subject to certain statutory and regulatory exceptions (including exceptions relating to certain managed care, discount, group purchasing and personal services arrangements), Federal law prohibits the payment or receipt of remuneration to induce, arrange for or recommend the purchase of health care items or services paid for in whole or in part by Medicare or state health care programs (including Medicaid programs or Medicaid waiver programs, such as TennCare (R)). Certain state laws may extend the prohibition to items or services that are paid for by private insurance and self-pay patients. Our arrangements with RxCare of Tennessee, Inc., a pharmacy services administrative organization owned by the Tennessee Pharmacists Association, and other pharmacy network administrators, drug manufacturers, marketing agents, brokers, health plan sponsors, pharmacies and others parties routinely involve payments to or from persons who provide or purchase, or recommend or arrange for the purchase of, items or services paid in part by the TennCare (R) program or by other programs covered by such laws. We carefully consider the importance of such "anti-kickback" laws when structuring our operations, and believe that we are in compliance with such laws. Violation of the Federal anti-kickback statute could subject us to criminal and/or civil penalties, including exclusion from Medicare and Medicaid (including TennCare (R)) programs or state-funded programs in the case of state enforcement. The federal anti-kickback law has been interpreted broadly by courts, the OIG and administrative bodies. Because of the federal statutes, broad scope, federal regulations establish certain safe harbors from liability. 5 Safe harbors exist for certain properly reported discounts received from vendors, certain investment interest, and certain properly disclosed payments made by vendors to group purchasing organizations, as well as for other transactions or relationships. In late 1999, HHS adopted final rules revising the discount safe harbor to protect certain rebates. Because this revision is fairly recent, the guidance on how the safe harbor revision will be interpreted is not fully developed. Nonetheless, a practice that does not fall within a safe harbor is not necessarily unlawful, but may be subject to scrutiny and challenge. In the absence of an applicable exception or safe harbor, a violation of the statute may occur even if only one purpose of a payment arrangement is to induce patient referrals or purchases. Among the practices that have been identified by the OIG as potentially improper under the statute are certain "product conversion programs" in which benefits are given by drug manufacturers to pharmacists or physicians for changing a prescription (or recommending or requesting such a change) from one drug to another. Anti-kickback laws have been cited as a partial basis, along with state consumer protection laws, for investigations and multi-state settlements relating to financial incentives provided by drug manufacturers to retail pharmacies in connection with such programs. Certain governmental entities have commenced investigations of PBM companies and other companies having dealings with the PBM industry and have identified issues concerning selection of drug formularies, therapeutic substitution programs and discounts or rebates from prescription drug manufacturers. Additionally, at least one state has filed a lawsuit concerning similar issues against a health plan. To date, we have not been the subject of any such investigation or suit and have not received subpoenas or been requested to produce documents for any such investigation or suit. However, there can be no assurance that we will not receive subpoenas or be requested to produce documents in pending investigations or litigations in the future. We believe that we are in compliance with the legal requirements imposed by the anti-remuneration laws and regulations, and we believe that there are material and substantial differences between drug switching programs that have been challenged under these laws and the therapeutic interchange practices and formulary management programs offered by us to our customers. However, there can be no assurance that we will not be subject to scrutiny or challenge under such laws or regulations, or that any such challenge would not have a material adverse effect upon us. Pending and future litigation could materially affect our relationships with pharmaceutical manufacturers or subject us to significant monetary damages. Since 1993, retail pharmacies have filed over 100 separate lawsuits against pharmaceutical manufacturers, wholesalers and certain PBMs, challenging brand name drug pricing practices under various state and federal antitrust laws. The plaintiffs alleged, among other things, that the manufacturers had offered, and certain PBMs had knowingly accepted, discounts and rebates on purchases of brand name prescription drugs that violated the Federal Sherman Act and the Federal Robinson-Patman Act. Some manufacturers settled certain of these actions, including a Sherman Act case brought on behalf of a nationwide class of retail pharmacies. The class action settlements generally provided for commitments by the manufacturers in their discounting practices to retail pharmacies. The defendants who did not settle won the 6 Sherman Act class action on a directed verdict. With respect to the cases filed by plaintiffs who opted out of the class action, some drug manufacturers have settled certain of these actions, but such settlements are not part of the public record. The Robinson-Patman Act cases are still pending. We are not currently a party to any of these proceedings. To date, we do not believe any of these settlements have had a material adverse effect on our business. However, we cannot provide any assurance that the terms of the settlements will not materially adversely affect us in the future or that we will not be made a party to any separate lawsuit. In addition, we cannot predict the outcome or possible ramifications to our business of the Robinson-Patman Act cases. If legislative or regulatory initiatives restrict our ability to use patient identifiable medical information, our clinical programs and our business growth strategy based on these services could suffer. Through our health improvement programs, we help our health plan sponsor customers identify individuals who will most benefit from the programs. Governmental restrictions on the use of patient identifiable information may adversely affect our ability to conduct health improvement programs and medical outcome studies and could adversely affect our growth strategy based on these programs. Federal and state legislation has been proposed, and some state laws have been enacted, to restrict the use and disclosure of patient identifiable medical information. Legislation could be enacted in the future that severely restricts or prohibits our use of patient identifiable information, which could harm our business, profitability and growth prospects. In December 2000, HHS issued final regulations regarding the privacy of individually-identifiable health information pursuant to the Health Insurance Portability and Accountability Act of 1996, or HIPAA. This final rule on privacy applies to both electronic and paper records and imposes extensive requirements on the way in which health care providers, health plan sponsors and their business associates use and disclose protected information. The final rule gives patients significant rights to understand and control how their protected health information is used and disclosed. Direct providers, such as pharmacies, are required to obtain patient consents for treatment, payment and health care operations. For all uses or disclosures of protected information that do not involve treatment, payment or health care operations, the rule requires that all covered entities obtain a valid patient authorization. In most cases, use or disclosure of protected health information must be limited to the minimum amount necessary to achieve the purpose of the use or disclosure. Organizations subject to the rule will have approximately two years to comply with its provisions. In addition, HHS has proposed, but not yet finalized, regulations pursuant to HIPAA that govern the security of individually-identifiable health information. Sanctions for failing to comply with standards issued pursuant to HIPAA include criminal penalties and civil sanctions. Due to the complex and controversial nature of the privacy regulations, they may be subject to court challenge, as well as further legislative and regulatory actions that could alter their effect. We cannot at this time predict with specificity what impact the recently adopted final rule on the privacy of individually-identifiable health information, or the proposed rule on security of individually-identifiable health information may have on us. However, they will likely increase our burden of regulatory compliance with respect to our health improvement programs and other information-based products, and may reduce the amount of information we may use if patients do not consent to such use. There can be no assurance that the restrictions and duties imposed by the recently adopted final rule on the privacy of individually-identifiable health information, or the proposed rule on security of individually-identifiable health information, will not have a material adverse effect on our business, profitability and growth prospects. 7 Even without new legislation and beyond the final federal regulations, individual health plan sponsor customers could prohibit us from including their patients' medical information in our various databases of medical data. They could also prohibit us from offering services that involve the compilation of such information. The loss of a key employee could cause our business to suffer. Our success is largely dependent on the services of Richard H. Friedman, our Chairman and Chief Executive Officer, and to a lesser extent, other key management personnel. We have an employment agreement with Mr. Friedman which provides for his continued employment. However, we cannot assure you that we will be able to retain his services or the services of any other key management personnel. The loss of the services of one or more of our senior management could cause our business, profitability and growth prospects to suffer. We have anti-takeover provisions that could delay or prevent a change in control, even if it would benefit stockholders. We have adopted anti-takeover provisions that could delay or prevent a third party from gaining control of us in a transaction that our board of directors has not negotiated and approved, even if such change in control would be beneficial to our stockholders. These anti-takeover provisions could depress the market price of our common stock. These anti-takeover provisions include: o change in control provisions in employment agreements with various executive officers; o restrictions on who may call a special meeting of stockholders; and o a stockholders' rights plan. The trading price of our common stock is volatile. The trading price of our common stock could be subject to wide fluctuations in response to quarter-to-quarter variations in our operating results, government regulatory action, general conditions in the pharmaceutical industry, increased price competition, changes in earnings estimates by analysts or other events or factors, many of which are beyond our control. In addition, the stock market has experienced extreme price and volume fluctuations. 8 SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS This prospectus may include or incorporate by referencecontain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, including statements regarding our expectations, hopes, beliefs, intentions or strategies regarding the future.

Stockholders’ Agreement

On January 24, 2010 the Company entered into a stockholders’ agreement, to which we refer as the Stockholders’ Agreement, with Kohlberg Investors V, L.P., Kohlberg Partners V, L.P., Kohlberg Offshore Investors V, L.P., Kohlberg TE Investors V, L.P., KOCO Investors V, L.P., to whom we refer collectively as the Kohlberg Stockholders, and Robert Cucuel, Mary Jane Graves, Nitin Patel, Joey Ryan, Colleen Lederer, Blackstone Mezzanine Partners II L.P., Blackstone Mezzanine Holdings II L.P., and S.A.C. Domestic Capital Funding, Ltd. Pursuant to the Stockholders’ Agreement, so long as the Kohlberg Stockholders or their affiliates beneficially own:

·at least 50% of the Initial Kohlberg Shares (as defined in the Stockholders’ Agreement), Kohlberg will be entitled to designate two directors toour board of directors; or, as applicable,

The Company will include the Kohlberg’s nominees in each slate of nominees recommended byour board of directors in connection with any stockholders’ meeting. If at any time the Kohlberg Stockholders and/or their affiliates beneficially own in the aggregate less than 15% of the Initial Kohlberg Shares, then the stockholder parties to the Stockholders’ Agreement will not have the right to designate any directors toour board of directors. Furthermore, until Kohlberg ceases to have the right to designate one or more directors at least one of such Kohlberg designees will be entitled to representation on each of the Audit Committee, the Management Development and Compensation Committee and the Corporate Strategy Committee ofour board of directors.

Additionally, the Stockholders’ Agreement provides that, subject to certain exceptions, until Kohlberg ceases to have the right to designate one or more directors, as described above, none of the Kohlberg Stockholders, Robert Cucuel, Mary Jane Graves, Nitin Patel, Joey Ryan, or Colleen Lederer, or any of their directors, officers or controlled affiliates, will:

·effect, offer, propose, or actively participate in (other than to the extent their stock is otherwise impacted), or assist any other person/entity to effect, offer or propose or participate in:

·any recapitalization, restructuring, liquidation, dissolution or other extraordinary transaction with respect to the Company or any material portion of its business; or

·any “solicitation” of “proxies” (as such terms are defined under the Exchange Act), and the rules and regulations promulgated thereunder, but without regard to the exclusion from the definition of “solicitation” set forth in Rule l4a-l(l)(2)(iv) of Regulation 14A under the Exchange Act) with respect to the Company or any action resulting in such person or entity becoming a “participant” in any “election contest” (as such terms are used in Regulation 14A) with respect to the Company;

·request the Company or any of its affiliates, directors, officers, employees, representatives, advisors or agents, directly or indirectly, to amend or waive in any respect the Stockholders’ Agreement or the certificate of incorporation or the bylaws of the Company or any of its affiliates.

Anti-Takeover Provisions

Provisions of the DGCL and ouramended and restated certificate of incorporation and amended and restated bylaws could make it more difficult to acquire us by means of a tender offer, a proxy contest or otherwise, or to remove incumbent officers and directors. These provisions are expected to discourage certain types of coercive takeover practices and takeover bids that our board of directors may consider inadequate and to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of increased protection of our ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging takeover or acquisition proposals because, among other things, negotiation of these proposals could result in an improvement of their terms. This summary below does not purport to be complete and is qualified in its entirety by reference to the DGCL and ouramended and restated certificate of incorporation and amended and restated bylaws.

Interested Stockholder Transactions under Delaware Law.

We are subject to Section 203 of the DGCL. Section 203 generally prohibits a Delaware corporation from engaging in any “business combination” with any “interested stockholder” for a period of three years after the date that such stockholder became an interested stockholder, unless:

·before such date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested holder;

·upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction began, excluding for purposes of determining the number of shares outstanding those shares owned by persons who are directors and also officers and 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 after such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

Section 203 defines “business combination” to include:

·any merger or consolidation involving the corporation and the interested stockholder;

·any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder;

·subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;
·any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; or

·the receipt by the interested stockholder of the benefit of any loss, advances, guarantees, pledges or other financial benefits by or through the corporation.

In general, Section 203 defines “interested stockholder” as an entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation or any entity or person affiliated with or controlling or controlled by such entity or person.

Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws.

Provisions in ouramended and restated certificate of incorporation and amended and restated bylaws may have the effect of discouraging or delaying certain transactions that may result in a change in control of our company or management, including transactions in which stockholders might otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our common stock. Among other things, ouramended and restated certificate of incorporation and amended and restated bylaws:

·provide that stockholders do not have cumulative voting rights.

·provide that stockholders do not have the power to call a special meeting.

·impose advance notice requirements and procedures with respect to stockholder proposals and the nomination of candidates for election as directors.

·provide that the Company indemnifies our officers and directors against losses incurred in investigations and legal proceedings resulting from their services to us, which may include service in connection with takeover defense measures.

·permit the Company to issue shares of common stock without any action by stockholders. These additional shares may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans.

Blank Check Preferred Stock

Our amended and restated certificate of incorporation provides for 5,000,000 shares of preferred stock. The existence of authorized but unissued shares of preferred stock may enable our board of directors to render more difficult or to discourage an attempt to obtain control of us by means of a merger, tender offer or otherwise. To the extent our board causes shares of our preferred stock to be issued, the voting or other rights of a potential acquirer might be diluted. Our board of directors has the authority to issue shares of our preferred stock without any action by our stockholders. Any such issuance may have the effect of delaying, deterring or preventing a change of control of us.

DESCRIPTION OF PREFERRED STOCK

Our amended and restated certificate of incorporation authorizes the issuance of up to 5,000,000 shares of preferred stock, par value $0.0001 per share. As of March 5, 2013, zero shares of preferred stock were issued and outstanding. Our board of directors, without further action of our stockholders,is authorized to provide for the issuance of the shares of preferred stock in series, and by filing a certificate pursuant to the DGCL, to establish from time to time the number of shares to be included in each series, and to fix the designation, powers, preferences, and relative rights of each such series and the qualifications, limitations, or restrictions thereof. Each class or series shall be appropriately designated by a distinguishing designation prior to the issuance of any shares thereof. The preferred stock of all series shall have powers, preferences and relative rights and shall be subject to qualifications, limitations and restrictions identical with those of other shares of the same series and, except to the extent otherwise provided in the description of the series, with those of shares of other series of the same class.

The DGCL provides that the holders of preferred stock will have the right to vote separately as a class on any proposal involving fundamental changes in the rights of holders of that preferred stock. This right is in addition to any voting rights that may be provided for in the applicable certificate of designation. Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of our common stock. Preferred stock could be issued quickly with terms designed to delay or prevent a change in control of our company or make removal of management more difficult. Additionally, the issuance of preferred stock may have the effect of decreasing the market price of our common stock.

DESCRIPTION OF DEBT SECURITIES

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

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

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

General

The indenture provides that debt securities may be issued from time to time in one or more series. The indenture does not limit the amount of debt securities that may be issued thereunder, and the indenture provides that the specific terms of any series of debt securities shall be set forth in, or determined pursuant to, an authorizing resolution, an officers’ certificate and/or a supplemental indenture, if any, relating to such series. 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 each prospectus supplement the following terms relating to a series of debt securities:

·the title or designation of the debt securities;

·any limit upon the aggregate principal amount of the debt securities;

·the date or dates on which we will pay the principal on the debt securities;

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

·the manner in which the amounts of payment of principal of, premium or interest on the debt securities will be determined, if these amounts may be determined by reference to an index based on a currency or currencies other than that in which the debt securities are denominated or designated to be payable or by reference to a commodity, commodity index, stock exchange index or financial index;

·the currency of denomination of the debt securities;

·if payments of principal of, premium or interest on the debt securities will be made in one or more currencies or currency units other than that or those in which the debt securities are denominated, the manner in which the exchange rate with respect to these payments will be determined;
·the place or places where the principal of, premium, and interest on the debt securities will be payable;

·the terms and conditions upon which we may redeem the debt securities;

·any obligation we have to redeem or purchase the debt securities pursuant to any sinking fund or analogous provisions or at the option of a holder of debt securities;

·the dates on which and the price or prices at which we will repurchase the debt securities at the option of the holders of debt securities and other detailed terms and provisions of these repurchase obligations;

·the denominations in which the debt securities will be issued, if other than denominations of $1,000 and any integral multiple thereof;

·the portion of principal amount of the debt securities payable upon declaration of acceleration of the maturity date, if other than the principal amount;

·whether the debt securities are to be issued at any OID and the amount of discount with which such debt securities may be issued;

·whether the debt securities will be issued in the form of certificated debt securities or global debt securities;

·the form of the debt securities;

·the terms and conditions upon which the debt securities will be so convertible or exchangeable into securities or property of another person, if at all, and any additions or changes, if any, to permit or facilitate such conversion or exchange;

·whether the debt securities will be subject to subordination and the terms of such subordination;

·any restriction or condition on the transferability of the debt securities;

·any addition or change in the provisions related to compensation and reimbursement of the trustee which applies to securities of such series;

·any addition to or change in the events of default described in this prospectus or in the indenture with respect to the debt securities and any change in the acceleration provisions described in this prospectus or in the indenture with respect to the debt securities;

·any addition to or change in the covenants described in this prospectus or in the indenture with respect to the debt securities; and

·any other terms of the debt securities, which may modify or delete any provision of the indenture.

Conversion or Exchange Rights

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

15

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

The indenture provides that we may not merge or consolidate with or into another entity, or sell other than for cash or lease all or substantially all our assets to another entity, or purchase all or substantially all the assets of another entity unless we are the surviving entity or, if we are not the surviving entity, the successor, transferee or lessee entity expressly assumes all of our obligations under the indenture or the debt securities, as appropriate.

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

Events of Default Under the Indenture

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

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

·if we fail to pay the principal, or premium, if any, when due whether by maturity or called for redemption;

·if we fail to pay a sinking fund installment, if any, when due and our failure continues for 30 days;

·if we fail to observe or perform any other covenant relating to such series contained in the debt securities of such series or the indenture, other than a covenant specifically relating to and for the benefit of holders of another series of debt securities, and our failure continues for 90 days after we receive written notice from the debenture trustee or holders of not less than a majority in aggregate principal amount of the outstanding debt securities of the applicable series; and

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

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

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

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

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

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

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

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

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

·the debenture trustee does not institute the proceeding, and does not receive from the holders of a majority in aggregate principal amount of the outstanding debt securities of that series (or at a meeting of holders of such series at which a quorum is present, the holders of a majority in principal amount of the debt securities of such series represented at such meeting) other conflicting directions within 60 days after the notice, request and offer.

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

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

Modification of Indenture; Waiver

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

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

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

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

·extending the fixed maturity of the series of debt securities;

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

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

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

·impairing the right to institute suit for the enforcement of any payment on or after the fixed maturity date of any series of debt securities;

·materially adversely affect the economic terms of any right to convert or exchange any debt securities; and

·reducing the percentage of debt securities, the holders of which are required to consent to any amendment or waiver; or modifying, without the written consent of the debenture trustee, the rights, duties or immunities of the debenture trustee.

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

Discharge

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

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

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

·maintain paying agencies;

·hold monies for payment in trust;

·compensate and indemnify the debenture trustee; and

·appoint any successor trustee.

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

Form, Exchange, and Transfer

We will issue the debt securities of each series only in fully registered form without coupons and, unless we otherwise specify in the applicable prospectus supplement, in denominations of $1,000 and any integral multiple thereof. The 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 a prospectus supplement with respect to that series.

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 or in the indenture, we will make no service charge for any registration of transfer or exchange, but we may require payment of any taxes or other governmental charges.

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

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

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

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

Information Concerning the Debenture Trustee

The debenture trustee, other than during the occurrence and continuance of an event of default under the indenture, undertakes to perform only those duties as are specifically set forth in the indenture. Upon an event of default under the indenture, the debenture 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 debenture 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, will we make interest payments by check which we will mail to the holder. Unless we otherwise indicate in a prospectus supplement, we will designate the corporate trust office of the debenture trustee our sole paying agent for payments with respect to debt securities of each series. We will name in the applicable prospectus supplement any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.

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

Governing Law

The indenture and the debt securities will be governed and construed in accordance with the laws of the State of New York.

Subordination of Subordinated Debt Securities

Any subordinated debt securities will be subordinate and junior in priority of payment to certain of our other indebtedness to the extent described in a prospectus supplement.

The indenture in the form initially filed as an exhibit to the registration statement of which this prospectus forms a part does not limit the amount of indebtedness which we may incur, including senior indebtedness or subordinated indebtedness as well as senior convertible indebtedness or subordinated convertible indebtedness, and does not limit us from issuing any other debt, including secured indebtedness or unsecured indebtedness.

Global Securities

The debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depository identified in an applicable subsequent filing and registered in the name of the depository or a nominee for the depository. In such a case, one or more global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal amount of outstanding debt securities of the series to be represented by the global security or securities. Unless and until it is exchanged in whole or in part for debt securities in definitive certificated form, a global security may not be transferred except as a whole by the depository for the global security to a nominee of the depository or by a nominee of the depository to the depository or another nominee of the depository or by the depository or any nominee to a successor depository for that series or a nominee of the successor depository and except in the circumstances described in an applicable subsequent filing.

We expect that the following provisions will apply to depository arrangements for any portion of a series of debt securities to be represented by a global security. Any additional or different terms of the depository arrangement will be described in an applicable subsequent filing.

Upon the issuance of any global security, and the deposit of that global security with or on behalf of the depository for the global security, the depository will credit, on its book-entry registration and transfer system, the principal amounts of the debt securities represented by that global security to the accounts of institutions that have accounts with the depository or its nominee. The accounts to be credited will be designated by the underwriters or agents engaging in the distribution of the debt securities or by us, if the debt securities are offered and sold directly by us. Ownership of beneficial interests in a global security will be limited to participating institutions or persons that may hold interests through such participating institutions. Ownership of beneficial interests by participating institutions in the global security will be shown on, and the transfer of the beneficial interests will be effected only through, records maintained by the depository for the global security or by its nominee. Ownership of beneficial interests in the global security by persons that hold through participating institutions will be shown on, and the transfer of the beneficial interests within the participating institutions will be effected only through, records maintained by those participating institutions. The laws of some jurisdictions may require that purchasers of securities take physical delivery of the securities in certificated form. The foregoing limitations and such laws may impair the ability to transfer beneficial interests in the global securities.

So long as the depository for a global security, or its nominee, is the registered owner of that global security, the depository or its nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the global security for all purposes under the applicable indenture. Unless otherwise specified in an applicable subsequent filing and except as specified below, owners of beneficial interests in the global security will not be entitled to have debt securities of the series represented by the global security registered in their names, will not receive or be entitled to receive physical delivery of debt securities of the series in certificated form and will not be considered the holders thereof for any purposes under the indenture. Accordingly, each person owning a beneficial interest in the global security must rely on the procedures of the depository and, if such person is not a participating institution, on the procedures of the participating institution through which the person owns its interest, to exercise any rights of a holder under the indenture.

The depository may grant proxies and otherwise authorize participating institutions to give or take any request, demand, authorization, direction, notice, consent, waiver or other action which a holder is entitled to give or take under the applicable indenture. We understand that, under existing industry practices, if we request any action of holders or any owner of a beneficial interest in the global security desires to give any notice or take any action a holder is entitled to give or take under the applicable indenture, the depository would authorize the participating institutions to give the notice or take the action, and participating institutions would authorize beneficial owners owning through such participating institutions to give the notice or take the action or would otherwise act upon the instructions of beneficial owners owning through them.

Unless otherwise specified in applicable subsequent filings, payments of principal, premium and interest on debt securities represented by a global security registered in the name of a depository or its nominee will be made by us to the depository or its nominee, as the case may be, as the registered owner of the global security.

We expect that the depository for any debt securities represented by a global security, upon receipt of any payment of principal, premium or interest, will credit participating institutions’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global security as shown on the records of the depository. We also expect that payments by participating institutions to owners of beneficial interests in the global security held through those participating institutions will be governed by standing instructions and customary practices, as is now the case with the securities held for the accounts of customers registered in street name, and will be the responsibility of those participating institutions. None of us, the debenture trustee or any agent of ours or the debenture trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial interests in a global security, or for maintaining, supervising or reviewing any records relating to those beneficial interests.

Unless otherwise specified in the applicable subsequent filings, a global security of any series will be exchangeable for certificated debt securities of the same series only if:

the depository for such global securities notifies us that it is unwilling or unable to continue as depository or such depository ceases to be a clearing agency registered under the Exchange Act and, in either case, a successor depository is not appointed by us within 90 days after we receive the notice or become aware of the ineligibility;

we in our sole discretion determine that the global securities shall be exchangeable for certificated debt securities; or

there shall have occurred and be continuing an event of default under the applicable indenture with respect to the debt securities of that series.

Upon any exchange, owners of beneficial interests in the global security or securities will be entitled to physical delivery of individual debt securities in certificated form of like tenor and terms equal in principal amount to their beneficial interests, and to have the debt securities in certificated form registered in the names of the beneficial owners, which names are expected to be provided by the depository's relevant participating institutions to the debenture trustee.

In the event that DTC acts as depository for the global securities of any series, the global securities will be issued as fully registered securities registered in the name of Cede & Co., DTC’s partnership nominee.The following information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy or completeness thereof.

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds and provides asset servicing for U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments from countries that DTC’s participants, referred to as direct participants, deposit with DTC. DTC also facilitates the post-trade settlement among direct participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between direct participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly, referred to as indirect participants. The DTC Rules applicable to its participants are on file with the SEC.

DTC is awholly-ownedsubsidiary of The Depository Trust & Clearing Company, or DTCC.DTCC is owned by the users of its regulated subsidiaries.DTCC, through its subsidiaries, provides clearing, settlement and information services for equities, corporate and municipal bonds, government and mortgage backed securities, money market instruments and over the-counter derivatives. In addition, DTCC is a leading processor of mutual funds and insurance transactions, linking funds and carriers with their distribution networks. DTCC’s customer base extends to thousands of companies within the global financial services industry. DTCC serves brokers, dealers, institutional investors, banks, trust companies, mutual fund companies, insurance carriers, hedge funds and other financial intermediaries – either directly or through correspondent relationships.

To facilitate subsequent transfers, the debt securities may be registered in the name of DTC’s nominee, Cede & Co. The deposit of the debt securities with DTC and their registration in the name of Cede & Co. will effect no change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the debt securities. DTC's records reflect only the identity of the direct participating institutions to whose accounts debt securities are credited, which may or may not be the beneficial owners. The participating institutions remain responsible for keeping account of their holdings on behalf of their customers.

Delivery of notices and other communications by DTC to direct participating institutions, by direct participating institutions to indirect participating institutions, and by direct participating institutions and indirect participating institutions to beneficial owners of debt securities are governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect.

Neither DTC nor Cede & Co. consents or votes with respect to the debt securities. Under its usual procedures, DTC mails a proxy to the issuer as soon as possible after the record date. The proxy assigns Cede & Co.’s consenting or voting rights to those direct participating institution to whose accounts the debt securities are credited on the record date.

If applicable, redemption notices shall be sent to Cede & Co. If less than all of the debt securities of a series represented by global securities are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participating institution in that issue to be redeemed.

To the extent that any debt securities provide for repayment or repurchase at the option of the holders thereof, a beneficial owner shall give notice of any option to elect to have its interest in the global security repaid by us, through its participating institution, to the debenture trustee, and shall effect delivery of the interest in a global security by causing the direct participating institution to transfer the direct participating institution's interest in the global security or securities representing the interest, on DTC’s records, to the debenture trustee. The requirement for physical delivery of debt securities in connection with a demand for repayment or repurchase will be deemed satisfied when the ownership rights in the global security or securities representing the debt securities are transferred by direct participating institutions on DTC's records.

DTC may discontinue providing its services as securities depository for the debt securities at any time. Under such circumstances, in the event that a successor securities depository is not appointed, debt security certificates are required to be printed and delivered as described above.

We may decide to discontinue use of the system of book-entry transfers through the securities depository. In that event, debt security certificates will be printed and delivered as described above.

DTCC is industry-owned by its customers who are members of the financial community, such as banks, broker/dealers, mutual funds and other financial institutions. DTCC operates on an at-cost basis, returning excess revenue from transaction fees to its member firms. All services provided by DTC are regulated by the SEC.

Unless otherwise specified in the applicable prospectus supplement, warrants may be exercised at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement at any time up to 5:00 p.m., New York City time, on the expiration date set forth in the applicable prospectus supplement. After 5:00 p.m., New York City time, on the expiration date, unexercised warrants will become void. Upon receipt of payment and the warrant certificate properly completed and duly executed, we will, as soon as practicable, issue the securities purchasable upon exercise of the warrant. If less than all of the warrants represented by the warrant certificate are exercised, a new warrant certificate will be issued for the remaining amount of warrants.

No Rights of Security Holder Prior to Exercise

Before the exercise of their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon the exercise of the warrants, and will not be entitled to:

in the case of warrants to purchase debt securities, payments of principal of, or any premium or interest on, the debt securities purchasable upon exercise; or

DESCRIPTION OF UNITS

We may, from time to time, issue units comprised of one or more of the other securities that may be offered under this prospectus, in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and soldobligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately at any time, or at any time before a specified date.

Any applicable prospectus supplement may describe, among other things:

the material terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;
any material provisions relating to the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units;
any special United States federal income tax considerations applicable to the units; and
any material provisions of the governing unit agreement that differ from those described above.

Underwriters, Agents and Dealers

We or any selling stockholder may designate agents who agree to use their reasonable efforts to solicit purchases for the period of their appointment or to sell our securities for which they have been appointed an agent on a continuing basis.

If we or any selling stockholder use underwriters for a sale of securities, the underwriters will acquire the securities for their own account. The underwriters may resell the 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.

Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. The obligations of the underwriters to purchase our securities will be subject to the conditions set forth in the applicable underwriting agreement. The underwriters may change from time to time any initial public offering price and any discounts or concessions the underwriters allow or reallow or pay to dealers. We or any selling stockholder may use underwriters with whom we or any selling stockholder have a material relationship. We will describe in an applicable prospectus supplement the name of the underwriter and the nature of any such relationship.

The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale. Transactions through brokers or dealers may include block trades in which the broker-dealer so engagedbrokers or dealers will attempt to sell such sharessecurities as agent but may position and resell a portion of the block as principal to facilitate the transaction; o purchases by a broker-dealer as principal and resale by such broker-dealer for its own account pursuant to this prospectus; o over-the-counter distributionstransaction or in accordance with the rules of the NASD; o ordinary brokerage transactions and transactionscrosses, in which the same broker solicits purchasers; and o privately negotiated transactions.

We will bear all expenses in connection with the registration of the common stock except that the selling stockholder will pay all underwriting commissions and similar selling expenses, brokerage fees and transfer taxes as well as fees of its counsel. In connection with any distributions of the shares, the selling stockholder may enter into hedging transactions with broker-dealers or other financial institutions who may engage in short sales of our common stock in the course of hedging the positions they assume with the selling stockholder. The selling stockholder also may (i) sell the common stock short and redeliver the shares to close outtrade. Any such short positions; (ii) enter into option or other transactions with broker-dealers or other financial institutions which require the delivery thereto of the shares offered hereby, which shares such broker-dealer or other financial institutions may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction); or (iii) pledge such shares to a broker-dealer or other financial institution, and, upon a default, such broker-dealer or other financial institution, may effect sales of such pledged shares pursuant to this prospectus (as supplemented or amended to reflect such transaction). In addition, any such shares that qualify for sale pursuant to Rule 144 under the Securities Act may be sold under that Rule rather than pursuant to this prospectus. In effecting sales, brokers, dealers or agents engaged by the selling stockholder may arrange for other brokers or dealers to participate. Brokers, dealers or agents may receive commissions, discounts or concessions from the selling stockholder in amounts to be negotiated prior to the sale. Such brokers or dealersdealer may be deemed to be "underwriters" within the meaning ofan underwriter, as such term is defined in the Securities Act, of the securities so offered and sold.

Underwriters, dealers and agents that participate in connection with such sales,the distribution of our securities may be underwriters as defined in the Securities Act, and any such commissions, discounts or concessionscommissions they receive from us and any profit on their resale of the securities may be deemed to betreated as underwriting discounts orand commissions under the Securities Act. 11 In order to comply with the securities laws of certain states, the shares must be sold in such states only through registered or licensed brokers or dealers. In addition, in certain states shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirements is availableUnderwriters, dealers and has been complied with. The rules and regulations in Regulation M under the Exchange Act provide that during the period that any person is engaged in the distribution (as defined therein) of common stock, such person generally may not purchase shares of our common stock. The selling stockholder may be subject to such regulation which may limit the timing of its purchases and sales of shares of the common stock. At the time a particular offer of shares is made, if required, a prospectus supplement will be distributed that will set forth the number of shares being offered and the terms of the offering, including the name of any underwriter, dealer or agent, the purchase price paid by any underwriter, any discount, commission and other item constituting compensation, any discount, commission or concession allowed or reallowed or paid to any dealer, and the proposed selling price to the public.

Stabilization Activities

In connection with an offering through underwriters, an underwriter may purchase and sell securities in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of securities than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ option to purchase additional securities from us in the offering, if any. If the underwriters have an over-allotment option to purchase additional securities from us, the underwriters may 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 shares through the over-allotment option. “Naked” short sales are any sales in excess of such option or where the underwriters do not have an 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 there may be downward pressure on the price of the securities in the open market after pricing that could adversely affect investors who purchase in the offering.

Accordingly, to cover these short sales positions or to otherwise stabilize or maintain the price of the securities, the underwriters may bid for or purchase securities in the open market and may impose penalty bids. If penalty bids are imposed, selling concessions allowed to syndicate members or other broker-dealers participating in the offering are reclaimed if securities previously distributed in the offering are repurchased, whether in connection with stabilization transactions or otherwise. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. The imposition of a penalty bid may also affect the price of the securities to the extent that it discourages resale of the securities. The magnitude or effect of any stabilization or other transactions is uncertain.

Direct Sales

We or any selling security holder may also sell securities directly to one or more purchasers without using underwriters or agents. In this case, no agents, underwriters or dealers would be involved. We may sell securities upon the exercise of rights that we may issue to our securityholders. We or any selling security holder may also sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities.
