FORWARD-LOOKING STATEMENTS

The statements we have made in this prospectus supplement or in documents incorporated by reference herein which are not historical facts are “forward-looking statements.” These forward-looking statements are based on currently available operating, financial and competitive information and are subject to various risks and uncertainties that could cause actual results to differ materially from the Company’s historical experience and its present expectations.

The discussions in our “Risk Factors” section of this prospectus supplement and the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of our Annual Report on Form 10-K for the fiscal year ended December 31, 2013, which we refer to as our 2013 10-K, highlight some of the more important risks identified by our management, but should not be assumed to be the only factors that could affect future performance. Other factors that could cause the actual results of our operations or our financial condition to differ from those expressed or implied in these forward-looking statements include, but are not limited to, inflation of and volatility in raw material and energy costs, continuing pressure for lower cost products, our ability to implement our business strategies, including productivity initiatives and cost reduction plans, our debt level, currency movements and other risks of conducting business internationally, our ability to successfully identify and integrate acquired businesses and achieve anticipated synergies from such acquisitions, and the impact of regulatory and litigation matters, including those that could impact our ability to utilize our net operating losses to offset taxable income and those that impact our ability to protect and use our intellectual property, and other factors described in our filings with the SEC.

Table of Contents

Except to the extent required by the federal securities laws, we undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. The foregoing review of factors should not be construed as exhaustive or as any admission regarding the adequacy of our disclosures. Certain risk factors are detailed from time to time in our various public filings. You are advised, however, to consult any further disclosures we make on related subjects in our filings with the SEC.

You can identify forward-looking statements by the fact that they do not relate strictly to historic or current facts. Forward-looking statements use terms such as “anticipates,” “believes,” “continues,” “could,” “estimates,” “expects,” “intends,” “may,” “plans,” “potential,” “predicts,” “preliminary,” “will,” “should,” “seeks,” “pro forma” or similar expressions in connection with any disclosure of future operating or financial performance. These statements are only predictions and involve known and unknown risks, uncertainties and other factors that may cause our actual results of operations, financial condition, levels of activity, performance or achievements to be materially different from any future results of operations, financial condition, levels of activity, performance or achievements expressed or implied by such forward-looking statements. You should not place undue reliance on these forward-looking statements.

INDUSTRY AND MARKET DATA

This prospectus supplement includes industry data and statistics that we obtained from periodic industry publications, including Resource Information System Inc., Paper Shipping Sack Manufacturers’ Association, Inc. and Paperboard Packaging Council, as well as our internal estimates. We believe data regarding the paperboard packaging industry and our market position and market share within the industry are inherently imprecise, but generally indicate size and position and market share within the industry. Industry publications generally state that the information contained therein has been obtained from sources believed to be reliable. Although we believe that the information provided by these third parties is generally accurate, we have not independently verified any of the data from third-party sources nor have we ascertained the underlying economic assumptions relied upon therein. While we are not aware of any misstatements regarding any industry data presented herein, our estimates, in particular as they relate to our general expectations concerning the paperboard packaging and flexible packaging industries, involve risks and uncertainties and are subject to change based on various factors, including those discussed under “Risk Factors” in this prospectus supplement and our 2013 10-K.

RISK FACTORS

You should consider carefully all of the information set forth or incorporated by reference in this prospectus supplement and, in particular, the risks described below as well as the risk factors set forth in our 2013 10-K before you decide to invest in our shares of common stock. If any of the following uncertainties or risks actually occurs, our business, financial condition or results of operations could be materially adversely affected. The selected risks described below and in our 2013 10-K are not the only risks that may affect your investment. Additional risks and uncertainties not currently known to us or that we currently view as immaterial may also materially and adversely affect our business, financial condition or results of operations.

Risks Related to Our Common Stock

Our common stock is an equity security and is subordinate to our existing and future indebtedness.

The shares of common stock are equity interests and do not constitute indebtedness. As such, the shares of common stock will rank junior to all of our indebtedness and to other non-equity claims on us and our assets available to satisfy claims on us, including claims in a bankruptcy, liquidation or similar proceeding. Our existing indebtedness restricts, and future indebtedness may restrict, payment of dividends on our common stock.

Unlike indebtedness, where principal and interest customarily are payable on specified due dates, in the case of common stock, (i) dividends are payable only when and if declared by our board of directors or a duly authorized committee of the board and (ii) as a corporation, we are restricted to only making dividend payments and repurchasing our common stock out of legally available assets. Further, our common stock places no restrictions on our business or operations or on our ability to incur indebtedness or engage in any transactions, subject only to the voting rights available to stockholders generally.

In addition, any of our rights (including the rights of the holders of our common stock) to participate in the assets of any of our subsidiaries upon any liquidation or reorganization of any subsidiary will be subject to the prior claims of that subsidiary’s creditors (except to the extent we may ourselves be a creditor of that subsidiary), including that subsidiary’s trade creditors and our creditors who have obtained or may obtain guarantees from the subsidiaries. As a result, our common stock will be subordinated to our and our subsidiaries’ obligations and liabilities, including our liabilities under our credit facilities and outstanding notes.

Our ability to pay any dividends on our common stock may be limited and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of our common stock.

We have not historically paid any dividends on our common stock. Our current financing arrangements limit our ability to pay cash dividends on our common stock and any other financing arrangements that we enter into in the future may contain similar restrictions. Even if any financing arrangements to which we are a party permit us to pay cash dividends, any determination to do so will be at the discretion of our board of directors and will be based upon our financial condition, operating results, capital requirements, plans for expansion, business opportunities, restrictions imposed by any of our financing arrangements, provisions of applicable law and any other factors that our board of directors determines are relevant at that point in time.

The market price and trading volume of our common stock has been and may continue to be volatile, which could cause the value of your investment to decline.

The market price and trading volume of our common stock has been subject to volatility and, in the future, the market price and trading volume of our common stock could fluctuate widely in response to numerous factors, many of which are beyond our control. During the period from January 1, 2010 to February 10, 2014, the price per share for our common stock fluctuated from a high of $10.23 per share to a low of $2.85 per share. In addition to factors contemplated by the risk factors discussed in this prospectus supplement, the accompanying prospectus and the other documents incorporated herein and therein by reference, the price and trading volume of our common stock may be affected by:

S-10

Table of Contents

If we, the selling stockholders or other significant stockholders sell an additional large number of shares of our common stock, the market price of our common stock could decline.

The market price of our common stock could decline as a result of sales of a large number of shares of common stock in the market or the perception that such sales could occur. These sales, or the possibility that these sales may occur, also might make it more difficult for us to issue equity securities in the future at a time and at a price that we deem appropriate. We, the selling stockholders, and the Coors Family Stockholders have agreed not to offer or sell, dispose of or hedge, directly or indirectly, any common stock without the permission of the underwriter for a period of 45 days from the date of this prospectus supplement, subject to certain exceptions. In addition and pursuant to a registration rights agreement entered into with the selling stockholders and certain of our other stockholders, we have granted the selling stockholders and certain of our other stockholders the right to cause us, in certain instances, at our expense, to file registration statements under the Securities Act of 1933, as amended, which we refer to as the Securities Act, covering resales of our common stock held by them or to piggyback on a registration statement covering shares of common stock offered by the Company in certain circumstances. To the extent that such registration rights are exercised, the resulting sale of a substantial number of shares of our common stock into the market could cause the market price of our common stock to decline. The selling stockholders’ shares also may be sold pursuant to Rule 144 under the Securities Act, depending on their holding period and subject to certain additional restrictions in the case of shares held by persons deemed to be our affiliates. As restrictions on resale end, the market price of our common stock could also decline if the holders sell them or are perceived by the market as intending to sell them.

The TPG Entities and the Coors Family Stockholders will continue to have significant influence over us, including in connection with decisions that require the approval of our stockholders, which could limit your ability to influence the outcome of key transactions, including a change of control.

After giving effect to this offering, the TPG Entities and the Coors Family Stockholders are expected to beneficially own approximately 13.4% of our outstanding common stock. As a result, the TPG Entities and the Coors Family Stockholders potentially have the ability to influence the outcome of matters that require a vote of our stockholders, including the election of our board of directors and other corporate transactions, regardless of whether others believe that the transaction is in our best interests. The interests of the TPG Entities and the Coors Family Stockholders may not be fully aligned with interests of other stockholders and this could lead to a strategy that is not in the interests of other stockholders. The concentrated holdings of the TPG Entities and the Coors Family Stockholders may delay or deter possible

S-11

Table of Contents

changes in control of the Company, which may reduce the market price of our common stock, or may otherwise result in the Company either taking actions that our other stockholders do not support or failing to take actions that our other stockholders do support.

The issuance of shares of preferred stock could adversely affect holders of common stock, which may negatively impact your investment.

Our board of directors is authorized to cause us to issue classes or series of preferred stock without any action on the part of our stockholders. The board of directors also has the power, without stockholder approval, to set the terms of any such classes or series of preferred shares that may be issued, including the designation, preferences, limitations and relative rights over our common stock with respect to dividends or upon the liquidation, dissolution or winding up of our business and other terms. If we issue preferred shares in the future that have a preference over the common stock with respect to the payment of dividends or upon liquidation, dissolution or winding up, or if we issue preferred shares with voting rights that dilute the voting power of the common stock, the rights of holders of our common stock or the market price of the common stock could be adversely affected. As of the date of this prospectus supplement, we have no outstanding shares of preferred stock but we have 100 million authorized but unissued shares of preferred stock available for issuance.

Our certificate of incorporation, by-laws, stockholder rights plan and Delaware law may discourage takeovers and business combinations that our stockholders might consider in their best interests.

Provisions in our certificate of incorporation and by-laws, our stockholder rights plan and provisions of Delaware corporate law may delay, deter, prevent or render more difficult a takeover attempt which is not approved by our board of directors but which our stockholders might consider in their best interests. These provisions include:

These provisions may prevent our stockholders from receiving the benefit from any premium to the market price of our common stock offered by a bidder in a takeover context. Even in the absence of a takeover attempt, the existence of these provisions may adversely affect the prevailing market price of our common stock if they are viewed as discouraging takeover attempts in the future. These provisions may also make it difficult for stockholders to replace or remove our management.

CERTAIN U.S. FEDERAL INCOME AND ESTATE TAX CONSEQUENCES TO

NON-U.S. HOLDERS OF COMMON STOCK

The following is a general discussion of certain U.S. federal income and estate tax consequences of the purchase, ownership and disposition of our common stock that may be relevant to you if you are a non-U.S. holder (as defined below) that acquires our common stock pursuant to this offering. This discussion is limited to non-U.S. holders who hold our common stock as capital assets within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended, which we refer to as the Code.

This discussion does not address all aspects of U.S. federal income and estate taxation that may be relevant to you in light of your particular circumstances, and does not address any state, local, foreign or other U.S. federal tax consequences (such as U.S. gift tax consequences). Furthermore, this discussion does not consider all U.S. federal income tax consequences that may be relevant to a particular non-U.S. holder in light of the holder’s specific facts and circumstances or to non-U.S. holders subject to special rules under the U.S. federal income tax laws, including banks, insurance companies, financial institutions, partnerships or other pass-through entities (or investors therein), holders of 10-percent or more of our common stock, U.S. expatriates, “controlled foreign corporations”, “passive foreign investment companies”, and shareholders of such corporations, dealers and traders in securities, or persons that hold our common stock as part of a straddle, hedge, or conversion transaction. This discussion is based on provisions of the Code, U.S. Treasury regulations promulgated thereunder, and judicial decisions and current administrative rulings and practice, all as in effect and available as of the date of this prospectus supplement, and all of which are subject to change or differing interpretation, possibly with retroactive effect, which could result in tax consequences different from those as discussed below. If you are considering buying our common stock, you should consult your own tax advisor about current and possible future U.S. federal income and estate tax consequences of purchasing, owning and disposing of our common stock in your particular situation, as well as tax consequences arising under any state, local or foreign tax laws, any other U.S. federal tax laws, and any applicable tax treaty.

For purposes of this discussion, a “non-U.S. holder” is a beneficial owner of our common stock that is not any of the following for U.S. federal income tax purposes:

A modified definition of non-U.S. holder applies for U.S. federal estate tax purposes (as discussed below).

If an entity taxable as a partnership for U.S. federal income tax purposes holds shares of our common stock, the U.S. federal income tax treatment of a partner in such partnership generally will depend on the status of the partner and upon the activities of the partnership. Partnerships and their partners should consult their own tax advisors as to the tax consequences to them of the purchase, ownership and disposition of our common stock.

Distributions on our Common Stock

If distributions are paid on shares of our common stock, these distributions generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles, and then will constitute a return of capital that is applied against and reduces your adjusted tax basis in our common stock to the extent the distributions exceed those earnings and profits. Distributions in excess of our current and accumulated earnings and profits and your adjusted tax basis in our common stock (determined on a share by share basis) will be treated as a gain from the sale or exchange of our common stock, the treatment of which is discussed below. Dividends paid to a non-U.S. holder that are not “effectively connected” with the conduct of a trade or business within the U.S. of the

S-17

Table of Contents

non-U.S. holder will be subject to U.S. federal withholding tax at a 30-percent rate or, if an income tax treaty applies and certain certification requirements are satisfied (as described below), a lower rate specified by the treaty. Non-U.S. holders should consult their own tax advisors regarding their entitlement to benefits under a relevant tax treaty.

The U.S. federal withholding tax generally is imposed on the gross amount of a distribution, regardless of whether we have sufficient earnings and profits to cause the distribution to be a dividend for U.S. federal income tax purposes.

A non-U.S. holder that is eligible for a reduced rate of U.S. federal withholding tax under a tax treaty may establish its entitlement to the benefit of a reduced rate of withholding under such tax treaty by timely filing a properly completed Internal Revenue Service (“IRS”) Form W-8BEN (or a successor form) with us prior to the payment of a dividend. A non-U.S. holder eligible for a reduced rate of U.S. federal withholding tax under a tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for a refund together with the required information with the IRS.

Dividends paid on our common stock that are effectively connected with a non-U.S. holder’s conduct of a trade or business within the U.S. are exempt from U.S. federal withholding tax if the non-U.S. holder timely furnishes to us or the applicable withholding agent a properly completed IRS Form W-8ECI (or successor form) containing the non-U.S. holder’s taxpayer identification number. However, dividends exempt from U.S. federal withholding tax because they are effectively connected with the conduct of a U.S. trade or business are subject to U.S. federal income tax on a net income basis at the regular graduated U.S. federal income tax rates in the same manner as if the holder were a resident of the U.S. (unless an applicable income tax treaty provides otherwise). In addition, if the non-U.S. holder is a foreign corporation, any effectively connected earnings and profits may, under certain circumstances, be subject to an additional U.S. “branch profits tax” at a 30-percent rate (or a lower rate if specified by an applicable tax treaty).

Gain on Disposition of our Common Stock

A non-U.S. holder generally will not be subject to U.S. federal income tax or withholding tax with respect to gain recognized on a sale or other disposition of our common stock unless one of the following applies:

S-18

Table of Contents

Information Reporting and Backup Withholding

We must report annually to the IRS and to each non-U.S. holder the amount of dividends on our common stock paid to that holder and the tax, if any, withheld with respect to those dividends. These information reporting requirements apply even if withholding was not required. Pursuant to an applicable tax treaty or other agreement, copies of the information returns reporting those dividends and withholding may also be made available to the tax authorities in the country in which the non-U.S. holder resides.

Backup withholding (at a rate of 28%) generally will not apply to payments of dividends on common stock provided the non-U.S. holder furnishes to us or the applicable withholding agent the required certification of its non-U.S. status (generally a IRS Form W-8BEN or IRS Form W-8ECI) and the payor does not have actual knowledge or reason to know that such holder is a “United States person” as defined in the Code, or otherwise establishes an exemption.

Information reporting and, depending on the circumstances, backup withholding will apply to the proceeds of a sale of our common stock within the United States or conducted through certain United States-related financial intermediaries, unless the beneficial owner certifies under penalty of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that the beneficial owner is a United States person as defined under the Code), or such owner otherwise establishes an exemption.

Amounts withheld under the backup withholding rules do not constitute an additional U.S. federal income tax. Rather, any amounts withheld under the backup withholding rules will be refunded or allowed as a credit against the holder’s U.S. federal income tax liability, if any, provided the required information and appropriate claim for refund is timely filed with the IRS. Non-U.S. holders should consult their own tax advisors regarding the application of the information reporting and backup withholding rules to them.

Foreign Accounting Tax Compliance Act

Under Sections 1471 through 1474 of the Code, the final Treasury regulations promulgated thereunder, and subsequent IRS administrative guidance (commonly referred to as “FATCA”), a U.S. withholding agent may be required to withhold 30% of any dividends paid after June 30, 2014 and the gross proceeds of a sale of our common stock paid after December 31, 2016 to a foreign entity (whether such foreign entity is the beneficial owner or an intermediary) unless such foreign entity agrees to comply with certain certification, reporting and withholding obligations (which may include entering into an agreement with the IRS), or otherwise satisfies the requirements of an applicable FATCA intergovernmental agreement. Non-U.S. holders should contact their own tax advisors regarding the particular consequences to them of the application of FATCA.

U.S. Federal Estate Tax

Common stock owned or treated as owned by an individual who is not a citizen or resident, as defined for U.S. federal estate tax purposes, of the United States at the time of death will be included in that individual’s gross estate for U.S. federal estate tax purposes and may be subject to U.S. federal estate tax, unless an applicable estate tax treaty provides otherwise.

The foregoing discussion is a summary of certain U.S. federal income and estate tax consequences of the purchase, ownership and disposition of our common stock by non-U.S. holders. You are urged to consult your own tax advisor with respect to the particular tax consequences to you of the purchase, ownership and disposition of our common stock, including the effect of any U.S. state, local, non-U.S. tax consequences or other applicable tax laws.

UNDERWRITING

The underwriter named below, the selling stockholders and the Company have entered into an underwriting agreement with respect to the shares of common stock being offered. Subject to certain conditions, the underwriter has agreed to purchase the number of shares of common stock indicated in the following table from the selling stockholders.

The underwriter is committed to take and pay for all of the shares of common stock being offered, if any are taken.

The underwriter is purchasing the shares of common stock from the selling stockholders at $         per share (representing $         of aggregate proceeds to the selling stockholders). The underwriter may offer the shares of common stock from time to time for sale in one or more transactions on the NYSE, in the over-the-counter market, through negotiated transactions or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. In connection with the sale of the shares of common stock offered hereby, the underwriter may be deemed to have received compensation in the form of underwriting discounts. The underwriter may effect such transactions by selling shares of common stock to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriter and/or purchasers of shares of common stock for whom it may act as an agent or to whom it may sell as a principal. The offering of the shares of common stock by the underwriter is subject to receipt and acceptance and subject to the underwriter’s right to reject any order in whole or in part.

The Company, the selling stockholders and the Coors Family Stockholders have agreed that they will not, directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any shares of common stock or any securities convertible into or exchangeable or exercisable for common stock or, with respect to the Company, file any registration statement under the Securities Act in respect of, any shares of common stock or securities exchangeable for or convertible into shares of common stock (other than as contemplated by the underwriting agreement), without the prior written consent of the underwriter for a period of 45 days after the date of this prospectus supplement.

In connection with this offering, the underwriter may purchase and sell shares of common stock 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 underwriter of a greater number of shares than it is required to purchase in this offering. The underwriter may close out any covered short position by purchasing shares of common stock in the open market. A short position is more likely to be created if the underwriter is concerned that there may be downward pressure on the price of the shares of common stock in the open market after pricing that could adversely affect investors who purchase in this offering. Stabilizing transactions consist of various bids for or purchases of shares of common stock made by the underwriter in the open market prior to the completion of the offering.

Purchases to cover a short position and stabilizing transactions, as well as other purchases by the underwriter for its own account, may have the effect of preventing or retarding a decline in the market price of the Company’s common stock, and together with the imposition of the penalty bid, may stabilize, maintain or otherwise affect the market price of the common stock. As a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued at any time. These transactions may be effected on the NYSE, in the over-the-counter market or otherwise.

The Company estimates that its portion of the total expenses of the offering, excluding underwriting discounts and commissions, will be approximately $500,000.

The Company and the selling stockholders have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act.

In the ordinary course of the underwriter’s and its affiliates’ various business activities, the underwriter and its affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of the Company. The underwriter and its affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

European Economic Area

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”), the underwriter has represented and agreed that with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State (the “Relevant Implementation Date”) it has not made and will not make an offer of shares of common stock which are the subject of the offering contemplated by this prospectus supplement and the accompanying prospectus to the public in that Relevant Member State other than:

(c) in any other circumstances falling within Article 3(2) of the Prospectus Directive, provided that no such offer of shares of common stock shall require the Company or any underwriter to publish a prospectus pursuant to Article 3 of the Prospectus Directive.

For the purposes of this provision, the expression of an offer of shares to the public in relation to any shares of common stock in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the shares of common stock to be offered so as to enable an investor to decide to purchase shares of common stock, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, the expression Prospectus Directive means Directive 2003/71/EC (and amendments thereto, including the 2010 PD Amending Directive, to the extent implemented in the Relevant Member State), and includes any relevant implementing measure in the Relevant Member State and the expression 2010 PD Amending Directive means Directive 2010/73/EU.

OUR COMPANY

We are a leading provider of innovative packaging solutions for a wide variety of products to the global food, beverage and consumer products industries. We are the largest U.S. producer of folding cartons and we believe we are the only publicly traded company that has a majority of its sales derived from paperboard packaging. We are also the largest North American producer of coated unbleached kraft paperboard and coated recycled boxboard, which we use predominately for the internal production of our folding carton products. We also have leading U.S. market positions in multi-wall bags and heat transfer labels.

Our customers include some of the world’s most widely recognized companies who have well-known consumer brands. A majority of our sales are under multi-year contracts. For many of our beverage packaging customers, we provide proprietary packaging machines that pack bottles and cans into beverage carrier cartons. We also provide packaging machines and labels for other consumer products. These proprietary packaging systems help drive sales to our customers. We provide our customers with value-added packaging solutions designed to deliver marketing and performance benefits at a competitive cost by capitalizing on our low-cost paperboard mills and converting plants, proprietary carton and packaging designs and commitment to customer service.

We report our results in two business segments: paperboard packaging and flexible packaging.

Table of Contents

DESCRIPTION OF CAPITAL STOCK

Overview

Our restated certificate of incorporation authorizes 1 billion shares of common stock, par value $0.01 per share, and 100 million shares of preferred stock, par value $0.01 per share. Approximately 389.2 million shares of our common stock are issued and outstanding as of August 31, 2011, and no shares of preferred stock are issued and outstanding.

The following descriptions of our capital stock and provisions of our restated certificate of incorporation and amended and restated by-laws are summaries of their material terms and provisions and are qualified by reference to the complete text of our certificate of incorporation and by-laws, which are incorporated by reference in their entirety and filed as exhibits to the registration statement of which this prospectus is a part.

Common Stock

Holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not have cumulative voting rights. Holders of common stock are entitled to receive proportionately any dividends that may be declared by our board of directors, subject to the preferences and rights of any shares of preferred stock. In the event of our liquidation, dissolution or winding-up, holders of common stock will be entitled to receive proportionately any of our assets remaining after the payment of debts and liabilities and subject to the preferences and rights of any shares of preferred stock. Holders of common stock have no preemptive, subscription, redemption or conversion rights. The rights and privileges of holders of our common stock will be subject to any series of preferred stock that we may issue in the future, as described below.

Preferred Stock

Our certificate of incorporation provides that our board of directors has the authority, without further vote or action by our stockholders, to issue up to 100 million shares of preferred stock in one or more series and to fix the number of shares constituting any such series and the preferences, limitations and relative rights, including but not limited to, dividend rights, dividend rate, voting rights, terms of redemption, redemption price or prices, conversion rights and liquidation preferences of the shares constituting any series. The issuance of preferred stock could adversely affect the rights of holders of common stock.

Our certificate of incorporation authorizes shares of preferred stock that may be designated Series A junior participating preferred stock in connection with our stockholder rights plan. See “—Stockholder Rights Plan” below.

Change of Control Related Provisions

A number of provisions in our certificate of incorporation and by-laws and under the Delaware General Corporation Law, or the DGCL, may make it more difficult for third parties to acquire control of us. These provisions may have the effect of delaying, deferring, discouraging, preventing or rendering more difficult a future takeover attempt which is not approved by our board of directors, but which individual stockholders may deem to be in their best interests or in which stockholders may receive a substantial premium for their shares over then current market prices. As a result, stockholders who might desire to participate in such a transaction may not have an opportunity to do so. In addition, these provisions may adversely affect the prevailing market price of the common stock. These provisions are intended to:

Table of Contents

Unissued Shares of Common Stock

There are currently outstanding approximately 389.2 million shares of our authorized common stock. The remaining shares of authorized and unissued common stock are available for future issuance without additional stockholder approval, except as may be required by the rules or regulations of the New York Stock Exchange (“NYSE”) or other stock exchange on which our common stock may be listed. While the additional shares are not designed to deter or prevent a change of control, under some circumstances we could use the additional shares to create voting impediments or to frustrate persons seeking to effect a takeover or otherwise gain control by, for example, issuing those shares in private placements to purchasers who might side with our board of directors in opposing a hostile takeover bid.

Unissued Shares of Preferred Stock

Our certificate of incorporation grants our board of directors the authority, without any further vote or action by our stockholders, except as may be required by the rules or regulations of the NYSE or other stock exchange on which our common stock may be listed, to issue preferred stock in one or more series and to fix the number of shares constituting any such series and the preferences, limitations and relative rights, including but not limited to, dividend rights, dividend rate, voting rights, terms of redemption, redemption price or prices, conversion rights and liquidation preferences of the shares constituting any series. The existence of authorized but unissued preferred stock could reduce our attractiveness as a target for an unsolicited takeover bid since we could, for example, issue shares of preferred stock to parties who might oppose such a takeover bid or shares that contain terms the potential acquirer may find unattractive. This may have the effect of delaying or preventing a change in control, may discourage bids for the common stock at a premium over the market price of the common stock, and may adversely affect the market price of, and the voting and other rights of the holders of, common stock.

Classified Board of Directors, Vacancies and Removal of Directors

Our certificate of incorporation and by-laws provide that our board of directors is divided into three classes of even number or nearly even number, with each class elected for staggered three-year terms expiring in successive years. Any effort to obtain control of our board of directors by causing the election of a majority of the board of directors may require more time than would be required without a staggered board structure. Under the DGCL, for companies like us with a classified board of directors, stockholders may remove directors only for cause. Vacancies (including a vacancy created by increasing the size of the board) in our board of directors may only be filled by a majority vote of our directors. Any director elected to fill a vacancy will hold office for the remainder of the full term of the class of directors in which the vacancy occurred (including a vacancy created by increasing the size of the board) and until such director’s successor shall have been duly elected and qualified. No decrease in the number of directors will shorten the term of any incumbent director. Our certificate of incorporation and by-laws provide that the number of directors will be fixed and increased or decreased from time to time solely by resolution of the board of directors, but the board of directors will at no time consist of fewer than three directors. These provisions may have the effect of slowing or impeding a third party from initiating a proxy contest, making a tender offer or otherwise attempting a change in the membership of our board of directors that would effect a change of control.

Advance Notice Requirements for Nomination of Directors and Presentation of New Business at Meetings of Stockholders; Action by Written Consent

Our by-laws provide for advance notice requirements for stockholder proposals and nominations for director. Generally, to be timely, notice must be delivered to us not fewer than 90 days nor more than 120 days

10

Table of Contents

prior to the first anniversary date of the annual meeting for the preceding year. In addition, under the provisions of both our certificate of incorporation and by-laws, action may not be taken by written consent of stockholders; rather, any action taken by the stockholders must be effected at a duly called annual or special meeting. A special meeting may only be called by our board of directors. These provisions make it more procedurally difficult for a stockholder to place a proposal or nomination on the meeting agenda or to take action without a meeting, and therefore may reduce the likelihood that a stockholder will seek to take independent action to replace directors or seek a stockholder vote with respect to other matters that are not supported by management.

Business Combination under Delaware Law

We are subject to Section 203 of the DGCL. Subject to specified exceptions, Section 203, as currently in effect, 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:

A “business combination”, as further defined by the DGCL, includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. Except as otherwise described in the DGCL, an “interested stockholder” is defined to include (1) any person that is the owner of 15% or more of the outstanding voting stock of the corporation, or is an affiliate or associate of the corporation and was the owner of 15% or more of the outstanding voting stock of the corporation at any time within three years immediately before the date of determination, and (2) the affiliates and associates of any such person.

Certain stockholders that are members or affiliates of the Coors family (the “Coors Family Stockholders”) as well as certain investment partnerships organized by TPG Capital (the “TPG Entities”) that became stockholders as a result of the combination of the business of GPC with that of Altivity Packaging, LLC (the “Altivity Transaction”) and their respective affiliates or associates are not subject to the restrictions imposed by Section 203 because our board of directors approved the transactions, i.e., the business combinations, in which those stockholders became interested stockholders.

Limitation of Liability of Directors

Our certificate of incorporation provides that no director will be personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent that this limitation on or exemption from liability is not permitted by the DGCL. As currently enacted, the DGCL permits a corporation to provide in its certificate of incorporation that a director of the corporation will not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability for:

Table of Contents

The principal effect of this limitation on liability provision is that a stockholder will be unable to recover monetary damages against a director for breach of fiduciary duty unless the stockholder can demonstrate that one of the exceptions listed in the DGCL applies. The inclusion of this provision in our certificate of incorporation may discourage or deter stockholders or management from bringing a lawsuit against our directors for a breach of their fiduciary duties, even though such an action, if successful, might otherwise have benefited us and our stockholders. This provision should not affect the availability of equitable remedies such as an injunction or rescission of a transaction based upon a director’s breach of his or her fiduciary duties.

The DGCL provides that a corporation may indemnify its directors and officers as well as its other employees and agents against judgments, fines, amounts paid in settlement and expenses, including attorneys’ fees, actually and reasonably incurred in connection with various proceedings, other than an action brought by or in the right of the corporation, if such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, if he or she had no reasonable cause to believe his or her conduct was unlawful. A similar standard applies to actions brought by or in the right of the corporation, except that indemnification in such a case may only extend to expenses, including attorneys’ fees, incurred in connection with the defense or settlement of such actions, and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation.

Our certificate of incorporation and, with regard to our officers, our by-laws provide that we will indemnify our current and former directors, as well as any person who has agreed to become a director, and officers to the fullest extent permitted by the DGCL. Under these provisions and subject to the DGCL, we are required to indemnify our directors and officers for all judgments, fines, settlements, liabilities, losses, ERISA excise taxes or penalties, legal fees and other expenses actually and reasonably incurred in connection with pending or threatened legal proceedings because of the director’s or officer’s position with us or another entity that the director or officer serves as a director, officer, employee or agent at our request, subject to various conditions, and to advance funds to our directors and officers before final disposition of such proceedings to enable them to defend against such proceedings. To receive indemnification, the director or officer must have met the applicable standard of conduct required by Delaware law to be indemnified.

Unless otherwise ordered by a court, any indemnification of a present or former director, officer or employee of the Company shall be made by us (and may be made by us in the case of an agent) upon a determination that indemnification of such person is proper because he or she has met the applicable standard of conduct required by Delaware law to be indemnified. With respect to a person who is a director or officer at the time of such determination, such determination shall be made: (i) by a majority vote of the directors who are not parties to the proceeding, even though less than a quorum, (ii) a committee of such directors designated by a majority vote of such directors, even though less than a quorum, (iii) by independent legal counsel in a written opinion if there are no such directors or if such directors so direct, or (iv) by our stockholders. The by-laws also specifically authorize us to maintain insurance on behalf of any person who is or was or has agreed to become a director, officer, employee or agent, or is or was serving at our request as a director, officer, employee or agent of another entity, against certain liabilities.

Supermajority Voting Requirement for Amendment of Certain Provisions of Our Certificate of Incorporation and By-Laws

The provisions of our certificate of incorporation governing, among other things, our classified board of directors, the liability of directors and the elimination of the ability of stockholders to act by written consent, may not be amended, altered or repealed unless the amendment is approved by the vote of holders of 75% of the combined voting power of the then outstanding shares entitled to vote thereon. This requirement exceeds the majority vote of the outstanding stock that would otherwise be required by the DGCL for the repeal or amendment of such provisions of the certificate of incorporation. Our by-laws may be amended by the board of directors or by the vote of holders of 75% of the combined voting power of the then outstanding shares entitled to vote thereon. These provisions make it more difficult for any person to remove or amend any provisions that may have an anti-takeover effect.

Stockholder Rights Plan

We have adopted a stockholder rights plan under which each outstanding share of our common stock will be coupled with a stock purchase right. The description and terms of the rights can be found in a rights agreement between us and Wells Fargo Bank, N.A., as the rights agent. The following is a summary of the material provisions of the rights plan. This summary is qualified in its entirety by reference to the rights plan, which is attached as an exhibit to the registration statement of which this prospectus is a part and incorporated herein by reference in its entirety. This summary may not contain all of the information about the rights plan which is important to you, and we encourage you to read the rights plan in its entirety.

The rights are currently attached to the certificates representing outstanding shares of common stock, and no separate rights certificates will be distributed. The rights are transferable only with the common stock until a distribution date (as described below). Each right entitles the holder to purchase one one-thousandth of a share of our Series A junior participating preferred stock at an exercise price of $20.00, subject to adjustment. Each one one-thousandth of a share of Series A junior participating preferred stock will have economic and voting terms approximately equivalent to one share of our common stock. Until it is exercised, the right itself will not entitle the holder of the right to any rights as a stockholder, including the right to receive dividends or to vote at stockholder meetings.

The rights are not exercisable until the distribution date and will expire at the close of business on March 10, 2018, unless earlier redeemed or exchanged by us. As soon as practicable after the distribution date, we would issue separate certificates representing the rights which would trade separately from the shares of our common stock. A distribution date would generally occur upon the earlier of:

However, an acquiring person will not include us, any of our subsidiaries, any of our employee benefit plans or any person or entity acting under our employee benefit plans. In addition, an acquiring person will not include stockholders, including the Coors Family Stockholders and the TPG Entities, who beneficially owned 15% or more of our outstanding common stock immediately after the completion of the Altivity Transaction (referred to as “grandfathered persons,” provided that any such stockholder will cease to be a grandfathered person at such time when such stockholder beneficially owns less than 15% of our outstanding common stock).

If any person becomes an acquiring person, each right will represent, instead of the right to acquire one one-thousandth of a share of Series A junior participating preferred stock, the right to receive upon exercise a number of shares of common stock having a value equal to two times the purchase price of the right, subject to certain exceptions. All rights that are beneficially owned by an acquiring person or its transferee will become null and void.

If at any time after a public announcement has been made or we have received notice that a person has become an acquiring person and:

each right, except rights that previously have been voided as described above, will represent the right to receive, upon exercise, common stock of the acquiring company having a value equal to two times the purchase price of the right.

13

Table of Contents

At any time until the earlier of (1) the time we become aware that a person has become an acquiring person or (2) March 10, 2018, we may redeem all the rights at a price of $0.001 per right. At any time after a person has become an acquiring person and before the acquisition by such person and its affiliates of 50% or more of the outstanding shares of our common stock, we may exchange the rights, in whole or in part, at an exchange ratio of one share of common stock per right.

The purchase price of the rights, the number of thousandths of a share of Series A junior participating preferred stock and the amount of common stock, cash or other securities or property issuable upon exercise of, or exchange for, the rights, and the number of such rights outstanding, are subject to adjustment from time to time to prevent dilution. Except as provided in the rights agreement, no adjustment in the purchase price or the number of shares of Series A junior participating preferred stock issuable upon exercise of a right will be required until the cumulative adjustment would require an increase or decrease of at least 1% in the purchase price or number of shares for which a right is exercisable.

Before the time that a person or group becomes an acquiring person, and subject to specified limitations, the rights agreement may be supplemented or amended by us and the rights agent, without the approval of the holders of the rights.

The stockholder rights plan is designed to protect stockholders in the event of unsolicited offers to acquire us and other coercive takeover tactics which, in the opinion of our board of directors, could impair our ability to represent stockholder interests. The rights will not prevent a takeover of us. However, the provisions of the stockholder rights plan may render an unsolicited takeover more difficult or less likely to occur, even though such takeover may offer our stockholders the opportunity to sell their stock at a price above the prevailing market rate and/or may be favored by a majority of our stockholders.

Stockholders Agreement

The following is a summary of the material provisions of the stockholders agreement. This summary is qualified in its entirety by reference to the stockholders agreement, which is incorporated by reference in its entirety and is included as an exhibit to the registration statement of which this prospectus is a part. This summary may not contain all of the information about the stockholders agreement which is important to you, and we encourage you to read the stockholders agreement in its entirety.

Certain of our significant stockholders, including the Coors Family Stockholders, Clayton, Dubilier & Rice Fund V Limited Partnership (the “CDR Fund”), Old Town, S.A. (formerly known as EXOR Group S.A.) (“Old Town”), Field Holdings, Inc. and the TPG Entities, entered into the stockholders agreement in connection with the Altivity Transaction. The parties thereto have made certain agreements regarding matters further described below, that, among other things: (i) provides the covered stockholders certain rights to designate members of our board of directors and (ii) restricts the ability of the covered stockholders to transfer their shares of our common stock.

Designation Rights

The stockholders agreement provides that each of the Coors Family Stockholders, the CDR Fund, Old Town and the TPG Entities will have the right, subject to requirements related to stock ownership, to designate a certain number of individuals for nomination for election to our board of directors as described below. Each of the Coors Family Stockholders, the CDR Fund and Old Town is entitled to designate one individual for nomination for election to the board for so long as each such stockholder owns at least 3% of the fully diluted shares of our common stock.

The TPG Entities, as a group, are entitled to designate the following number of individuals for nomination for election to our board of directors for so long as they meet the requirements related to stock ownership specified below:

14

Table of Contents

The stockholders agreement further provides that each of our other directors, not designated in the manner described above, will be independent directors, as described below, designated for nomination by the nominating and corporate governance committee of our board.

Pursuant to the stockholders agreement, at each meeting of our stockholders at which directors are to be elected, we will recommend that our stockholders elect to the board of directors the designees of the individuals designated by the Coors Family Stockholders, the CDR Fund, Old Town and the TPG Entities. In addition, our then serving Chief Executive Officer shall be nominated for election to the board.

In the event that the Coors Family Stockholders, the CDR Fund, Old Town or the TPG Entities lose the right to designate a person to the board, such designee will resign immediately upon receiving notice from the nominating and corporate governance committee that it has identified a replacement director, and will resign in any event no later than 120 days after the designating person or entity loses the right to designate such designee to the board. The board seat formerly occupied by such designee shall become a seat for an additional independent director to be selected solely by the nominating and corporate governance committee or the board may determine to reduce its size by the number of vacated board seats.

An “independent director” is a director who: (i) is not an officer or employee of the Company or any of its affiliates, (ii) is not an officer or employee of any covered stockholder or, if such covered stockholder is a trust, a direct or indirect beneficiary of such trust and (iii) meets the standards of independence under applicable law and the requirements applicable to companies listed on the NYSE.

Agreement to Vote for Directors; Vacancies

Each covered stockholder is obligated to vote all of the shares owned by such covered stockholder in favor of the CEO director and each of the parties’ designees to the board, and to take all other steps within such covered stockholder’s power to ensure that the composition of the board is as contemplated by the stockholders agreement.

As long as the Coors Family Stockholders, the CDR Fund, Old Town or the TPG Entities, as the case may be, has the right to designate a person for nomination for election to the board, at any time at which the seat occupied by such party’s designee becomes vacant as a result of death, disability, retirement, resignation, removal or otherwise, such party will be entitled to designate for appointment by the remaining directors an individual to fill such vacancy and to serve as a director. We, along with each of the covered stockholders, have agreed to take such actions as will result in the appointment to the board as soon as practicable of any individual so designated by the Coors Family Representative, the CDR Fund, Old Town or the TPG Entities.

At any time at which a vacancy is created on the board as a result of the death, disability, retirement, resignation, removal or otherwise of one of the independent directors before the expiration of his or her term as director, the nominating and corporate governance committee will notify the board of a replacement who is an independent director. We, along with and the covered stockholders has agreed to take such actions as will result in the appointment of such replacement to the board as soon as practicable.

Actions of the Board of Directors; Affiliate Agreements

The stockholders agreement provides that actions of the board will require the affirmative vote of at least a majority of the directors present in person or by telephone at a duly convened meeting at which a quorum is

15

Table of Contents

present, or the unanimous written consent of the board, except that a board decision regarding the merger, consolidation or sale of substantially all our assets will require the affirmative vote of a majority of the directors then in office. In addition, a decision by us to enter into, modify or terminate any agreement with an affiliate of the Coors Family Stockholders, the CDR Fund, Old Town or the TPG Entities will require the affirmative vote of a majority of the directors not nominated by a covered stockholder which, directly or indirectly through an affiliate, has an interest in that agreement.

Committees of the Board of Directors

The stockholders agreement provides for the board to have an audit committee, a compensation and benefits committee and a nominating and corporate governance committee as follows:

The rights described above of each of the covered stockholders to have its director designee sit as a member of board committees will cease at such time as such stockholder holds less than 3% of the fully diluted shares of our common stock, and in the case of the two TPG Entities’ designees on the nominating and corporate governance committee, one such designee shall resign from the committee at such time as the TPG Entities have the right to designate only one director for nomination for election to the board. Our board of directors will fill any committee seats that become vacant in the manner provided in the preceding sentence with independent directors. The stockholders agreement prohibits the board from forming an executive committee.

Transfer Restrictions

DESCRIPTION OF THE DEBT SECURITIES

General

The following description of the terms of our senior debt securities and subordinated debt securities (together, the “debt securities”) sets forth certain general terms and provisions of the debt securities to which any prospectus supplement may relate. Unless otherwise noted, the general terms and provisions of our debt securities discussed below apply to both our senior debt securities and our subordinated debt securities. Our debt securities may be issued from time to time in one or more series. The particular terms of any series of debt securities and the extent to which the general provisions may apply to a particular series of debt securities will be described in the prospectus supplement relating to that series.

Debt securities may be issued either by GPHC or GPII. When describing any debt securities, references to “we”, “us” and “our” refer to the issuer of those debt securities.

The senior debt securities will be issued under an indenture between us and U.S. Bank National Association, as Senior Indenture Trustee (the “senior indenture”). The subordinated debt securities will be issued under an indenture between us and U.S. Bank National Association, as Subordinated Indenture Trustee (the “subordinated indenture” and, together with the senior indenture, the “indentures”). The Senior Indenture Trustee and the Subordinated Indenture Trustee are both referred to, individually, as the “Trustee.” The senior debt securities will constitute our unsecured and unsubordinated obligations and the subordinated debt securities will constitute our unsecured and subordinated obligations. A detailed description of the subordination provisions is provided below under the caption “—Ranking and Subordination—Subordination.” In general, however, if we declare bankruptcy, holders of the senior debt securities will be paid in full before the holders of subordinated debt securities will receive anything.

The statements set forth below are brief summaries of certain provisions contained in the indentures, which summaries do not purport to be complete and are qualified in their entirety by reference to the indentures, which are filed as exhibits to the registration statement of which this prospectus forms a part. Terms used herein that are otherwise not defined shall have the meanings given to them in the indentures. Such defined terms shall be incorporated herein by reference.

The indentures will not limit the amount of debt securities that may be issued under the applicable indenture, and debt securities may be issued under the applicable indenture up to the aggregate principal amount that may be authorized from time to time by us. Any such limit applicable to a particular series will be specified in the prospectus supplement relating to that series.

The prospectus supplement relating to any series of debt securities in respect of which this prospectus is being delivered will contain the following terms, among others, for each such series of debt securities:

18

Table of Contents

We may issue debt securities of any series at various times and we may reopen any series for further issuances from time to time without notice to existing holders of securities of that series.

Some of the debt securities may be issued as original issue discount debt securities. Original issue discount debt securities bear no interest or bear interest at below-market rates. These are sold at a discount below their stated principal amount. If we issue these securities, the prospectus supplement relating to such series of debt securities will describe any special tax, accounting or other information which we think is important. We encourage you to consult with your own tax and financial advisors on these important matters.

Unless we specify otherwise in the applicable prospectus supplement relating to such series of debt securities, the covenants contained in the indentures will not provide special protection to holders of debt securities if we enter into a highly leveraged transaction, recapitalization or restructuring.

19

Table of Contents

Unless otherwise set forth in the prospectus supplement relating to such series of debt securities, on each interest payment date, interest on outstanding debt securities will be paid to holders of record on the date that is 15 days prior to the date such interest is to be paid or, if not a business day, the next preceding business day. Unless otherwise specified in the prospectus supplement, debt securities will be issued in fully registered form only. Unless otherwise specified in the prospectus supplement, the principal amount of the debt securities will be payable at the corporate trust office of the Trustee in New York, New York. The debt securities may be presented for transfer or exchange at such office unless otherwise specified in the prospectus supplement, subject to the limitations provided in the applicable indenture, without any service charge, but we may require payment of a sum sufficient to cover any tax or other governmental charges payable in connection therewith.

Guarantees

The payment obligations of GPHC under any series of debt securities may be guaranteed by one or more of GPHC’s direct or indirect subsidiaries, including GPC, GPII or by other persons. The payment obligations of GPII under any series of debt security will be guaranteed fully and unconditionally by GPHC, and may be guaranteed by one or more of GPHC’s other direct or indirect subsidiaries or by other persons. If a series of debt securities is so guaranteed, the guarantors will execute a supplemental indenture or notation of guarantee as further evidence of their guarantee. The applicable prospectus supplement will describe the terms of any guarantee.

The obligations of each guarantor under its guarantee may be limited to the maximum amount that will not result in such guarantee obligations constituting a fraudulent conveyance or fraudulent transfer under federal or state law, after giving effect to all other contingent and fixed liabilities of that subsidiary and any collections from or payments made by or on behalf of any other guarantor in respect to its obligations under its guarantee.

Ranking and Subordination

General

The subordinated debt securities and the related guarantees will effectively rank junior in right of payment to any of our or the guarantors’ current and future secured obligations to the extent of the value of the assets securing such obligations. The debt securities and the guarantees will be effectively subordinated to all existing and future liabilities, including indebtedness and trade payables, of our non-guarantor subsidiaries. Unless otherwise set forth in the prospectus supplement relating to such series of debt securities, the indentures will not limit the amount of unsecured indebtedness or other liabilities that can be incurred by our non-guarantor subsidiaries.

Furthermore, GPHC is a holding company with no material business operations. GPHC’s ability to service its indebtedness and other obligations is dependent primarily upon the earnings and cash flows of its subsidiaries and the distribution or other payment to GPHC of such earnings or cash flows. In addition, certain indebtedness of GPHC’s subsidiaries contains, and future agreements relating to any indebtedness of its subsidiaries may contain, significant restrictions on the ability of its subsidiaries to pay dividends or otherwise make distributions to us.

Ranking of Debt Securities

The senior debt securities described in this prospectus will be unsecured, senior obligations of the issuing company and will rank equally with the issuing company’s other unsecured and unsubordinated obligations. Any guarantees of the senior debt securities will be unsecured and senior obligations of each of the guarantors, and will rank equally with all other unsecured and unsubordinated obligations of such guarantors. The subordinated debt securities will be unsecured, subordinated obligations and the any guarantees of the subordinated debt securities will be unsecured and subordinated obligations of each of the guarantors.

20

Table of Contents

Subordination

If issued, the indebtedness evidenced by the subordinated debt securities will be subordinate to the prior payment in full of all our Senior Indebtedness (as defined below). During the continuance beyond any applicable grace period of any default in the payment of principal, premium, interest or any other payment due on any of our Senior Indebtedness, we may not make any payment of principal of, or premium, if any, or interest on the subordinated debt securities. In addition, upon any payment or distribution of our assets upon any dissolution, winding up, liquidation or reorganization, the payment of the principal of, or premium, if any, and interest on the subordinated debt securities will be subordinated to the extent provided in the subordinated indenture in right of payment to the prior payment in full of all our Senior Indebtedness. Because of this subordination, if we dissolve or otherwise liquidate, holders of our subordinated debt securities may receive less, ratably, than holders of our Senior Indebtedness. The subordination provisions do not prevent the occurrence of an event of default under the subordinated indenture.

The subordination provisions also apply in the same way to each guarantor with respect to the Senior Indebtedness of such guarantor.

The term “Senior Indebtedness” of a person means with respect to such person the principal of, premium, if any, interest on, and any other payment due pursuant to any of the following, whether outstanding on the date of the subordinated indenture or incurred by that person in the future:

unless, in the case of any particular indebtedness, lease, renewal, extension or refunding, the instrument or lease creating or evidencing it or the assumption or guarantee relating to it expressly provides that such indebtedness, lease, renewal, extension or refunding is not superior in right of payment to the subordinated debt securities. Our senior debt securities, and any unsubordinated guarantee obligations of ours or any guarantor to which we and the guarantors are a party, including the guarantors’ guarantees of our debt securities and other indebtedness for borrowed money, constitute Senior Indebtedness for purposes of the subordinated indenture.

Pursuant to the subordinated indenture, the subordinated indenture may not be amended, at any time, to alter the subordination provisions of any outstanding subordinated debt securities without the consent of the requisite holders of each outstanding series or class of Senior Indebtedness (as determined in accordance with the instrument governing such Senior Indebtedness) that would be adversely affected thereby.

Consolidation, Merger, Conveyance or Transfer on Certain Terms

Except as described in the applicable prospectus supplement relating to such debt securities, we will not consolidate with or merge into any other entity or convey or transfer our properties and assets substantially as an entirety to any entity, unless:

Upon any consolidation or merger, or any conveyance or transfer of our properties and assets substantially as an entirety as set forth above, the successor person formed by such consolidation or into which we are merged or to which such conveyance or transfer is made shall succeed to, and be substituted for, and may exercise every right and power of ours under the applicable indenture with the same effect as if such successor had been named in the applicable indenture. In the event of any such conveyance or transfer, we, as the predecessor, shall be discharged from all obligations and covenants under the applicable indenture and the debt securities issued under such indenture and may be dissolved, wound up or liquidated at any time thereafter.

Certain Covenants

Any covenants pertaining to a series of debt securities will be set forth in a prospectus supplement relating to such series of debt securities.

Except as described in the prospectus and any applicable prospectus supplement relating to such series of debt securities, the indentures and the debt securities do not contain any covenants or other provisions designed to afford holders of debt securities protection in the event of a recapitalization or highly leveraged transaction involving us.

Certain Definitions

The following are certain of the terms defined in the indentures:

“GAAP” means generally accepted accounting principles as such principles are in effect in the United States as of the date of the applicable indenture.

“Significant Subsidiary” means any Subsidiary which would be a “significant subsidiary” as defined in Rule 1-02 of Regulation S-X, promulgated pursuant to the Securities Act of 1933 (the “Securities Act”), as in effect on the date of the applicable indenture.

“Subsidiary” means, with respect to any person, any corporation more than 50% of the voting stock of which is owned directly or indirectly by such person, and any partnership, association, joint venture or other entity in which such person owns more than 50% of the equity interests or has the power to elect a majority of the board of directors or other governing body.

Optional Redemption

Unless we specify otherwise in the applicable prospectus supplement, we may redeem any of the debt securities as a whole at any time or in part from time to time, at our option, on at least 15 days, but not more than 45 days, prior notice mailed to the registered address of each holder of the debt securities to be redeemed, at respective redemption prices equal to the greater of:

plus, in each case, accrued interest to the date of redemption that has not been paid (such redemption price, the “Redemption Price”).

“Comparable Treasury Issue” means, with respect to the debt securities, the U.S. Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term (“Remaining Life”) of the debt securities being redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the Remaining Life of such debt securities.

“Comparable Treasury Price” means, with respect to any redemption date for the debt securities: (1) the average of two Reference Treasury Dealer Quotations for that redemption date, after excluding the highest and lowest of four such Reference Treasury Dealer Quotations; or (2) if the Trustee obtains fewer than four Reference Treasury Dealer Quotations, the average of all quotations obtained by the Trustee.

“Independent Investment Banker” means one of the Reference Treasury Dealers, to be appointed by us.

“Reference Treasury Dealer” means four primary U.S. Government securities dealers to be selected by us.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by such Reference Treasury Dealer at 3:00 p.m., New York City time, on the third business day preceding such redemption date.

“Remaining Scheduled Payments” means, with respect to each debt security to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related redemption date but for such redemption; provided, however, that, if such redemption date is not an interest payment date with respect to such debt security, the amount of the next succeeding scheduled interest payment thereon will be deemed to be reduced by the amount of interest accrued thereon to such redemption date.

“Treasury Rate” means, with respect to any redemption date for the debt securities: (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury debt securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue; provided that if no maturity is within three months before or after the maturity date for the debt securities, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from those yields on a straight line basis, rounding to the nearest month; or (2) if that

23

Table of Contents

release, or any successor release, is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that redemption date. The Treasury Rate will be calculated on the third business day preceding the redemption date.

On and after the redemption date, interest will cease to accrue on the debt securities or any portion thereof called for redemption, unless we default in the payment of the Redemption Price, and accrued interest. On or before the redemption date, we shall deposit with a paying agent, or the applicable Trustee, money sufficient to pay the Redemption Price of and accrued interest on the debt securities to be redeemed on such date. If we elect to redeem less than all of the debt securities of a series, then the Trustee will select the particular debt securities of such series to be redeemed in a manner it deems appropriate and fair.

Defeasance

Except as otherwise set forth in the prospectus supplement relating to such series of debt securities, each indenture will provide that we, at our option,

in each case, if we deposit with the Trustee, in trust, money or the equivalent in securities of the government which issued the currency in which the debt securities are denominated or government agencies backed by the full faith and credit of such government, or a combination thereof, which through the payment of interest thereon and principal thereof in accordance with their terms will provide money in an amount sufficient to pay all the principal (including any mandatory sinking fund payments) of, and interest on, such series on the dates such payments are due in accordance with the terms of such series.

To exercise any such option, we are required, among other things, to deliver to the Trustee an opinion of counsel to the effect that the deposit and related defeasance would not cause the holders of such series to recognize income, gain or loss for federal income tax purposes and, in the case of a discharge pursuant to clause (a) above, accompanied by a ruling to such effect received from or published by the U.S. Internal Revenue Service.

In addition, we are required to deliver to the Trustee an officers’ certificate stating that such deposit was not made by us with the intent of preferring the holders over other creditors of ours or with the intent of defeating, hindering, delaying or defrauding creditors of ours or others.

Events of Default, Notice and Waiver

Except as otherwise set forth in the prospectus supplement relating to such series of debt securities, each indenture will provide that, if an Event of Default specified therein with respect to any series of debt securities issued thereunder shall have happened and be continuing, either the Trustee thereunder or the holders of 33-1/3% in aggregate principal amount of the outstanding debt securities of such series (or 33-1/3% in aggregate principal amount of all outstanding debt securities under such indenture, in the case of certain Events of Default affecting all series of debt securities issued under such indenture) may declare the principal of all the debt securities of such series to be due and payable.

Table of Contents

Except as otherwise set forth in the prospectus supplement relating to such series of debt securities, an “Event of Default” in respect of any series will be defined in the indentures as being any one of the following events:

Each indenture will provide that the Trustee thereunder will, within 90 days after the occurrence of a default with respect to the debt securities of any series issued under such indenture, give to the holders of the debt securities of such series notice of all uncured and unwaived defaults known to it; provided, however, that, except in the case of default in the payment of principal of, premium, if any, or interest, if any, on any of the debt securities of such series, the Trustee will be protected in withholding such notice if it in good faith determines that the withholding of such notice is in the interests of the holders of the debt securities of such series. The term “default” for the purpose of this provision means any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to debt securities of such series.

Each indenture will contain provisions entitling the Trustee under such indenture, subject to the duty of the Trustee during an Event of Default to act with the required standard of care, to be indemnified to its reasonable satisfaction by the holders of the debt securities before proceeding to exercise any right or power under the applicable indenture at the request of holders of such debt securities.

Each indenture will provide that the holders of a majority in aggregate principal amount of the outstanding debt securities of any series issued under such indenture may direct the time, method and place of conducting proceedings for remedies available to the Trustee or exercising any trust or power conferred on the Trustee in respect of such series, subject to certain conditions.

Except as otherwise set forth in the prospectus supplement relating to the debt securities, in certain cases, the holders of a majority in principal amount of the outstanding debt securities of any series may waive, on behalf of the holders of all debt securities of such series, any past default or Event of Default with respect to the debt securities of such series except, among other things, a default not theretofore cured in payment of the principal of, or premium, if any, or interest, if any, on any of the senior debt securities of such series or payment of any sinking or purchase fund or analogous obligations with respect to such senior debt securities.

Each indenture will include a covenant that we will file annually with the Trustee a certificate of no default or specifying any default that exists.

Modification of the Indentures

Except as set forth in the prospectus supplement relating to the debt securities, we and the Trustee may, without the consent of the holders of the debt securities issued under the indenture governing such debt securities, enter into indentures supplemental to the applicable indenture for, among others, one or more of the following purposes:

25

Table of Contents

No supplemental indenture for the purpose identified in clauses (2), (3) or (5) above may be entered into if to do so would adversely affect the rights of the holders of debt securities of any series issued under the same indenture in any material respect.

Except as set forth in the prospectus supplement relating to such series of debt securities, each indenture will contain provisions permitting us and the Trustee under such indenture, with the consent of the holders of a majority in principal amount of the outstanding debt securities of all series issued under such indenture to be affected voting as a single class, to execute supplemental indentures for the purpose of adding any provisions to or changing or eliminating any of the provisions of the applicable indenture or modifying the rights of the holders of the debt securities of such series to be affected, except that no such supplemental indenture may, without the consent of the holders of affected debt securities, among other things:

26

Table of Contents

In addition, the subordinated indenture will provide that we may not make any change in the terms of the subordination of the subordinated debt securities of any series in a manner adverse in any material respect to the holders of any series of subordinated debt securities without the consent of each holder of subordinated debt securities that would be adversely affected.

The Trustee

U.S. Bank National Association is the Trustee under each indenture. The Trustee and its affiliates may also provide banking, trustee and other services for, and transact other banking business with, us in the normal course of business.

Governing Law

The indentures will be governed by, and construed in accordance with, the laws of the State of New York.

Global Securities

We may issue debt securities through global securities. A global security is a security, typically held by a depositary, that represents the beneficial interests of a number of purchasers of the security. If we do issue global securities, the following procedures will apply.

We will deposit global securities with the depositary identified in the prospectus supplement. After we issue a global security, the depositary will credit on its book-entry registration and transfer system the respective principal amounts of the debt securities represented by the global security to the accounts of persons who have accounts with the depositary. These account holders are known as “participants.” The underwriters or agents participating in the distribution of the debt securities will designate the accounts to be credited. Only a participant or a person who holds an interest through a participant may be the beneficial owner of a global security. Ownership of beneficial interests in the global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the depositary and its participants.

We and the Trustee will treat the depositary or its nominee as the sole owner or holder of the debt securities represented by a global security. Except as set forth below, owners of beneficial interests in a global security will not be entitled to have the debt securities represented by the global security registered in their names. They also will not receive or be entitled to receive physical delivery of the debt securities in definitive form and will not be considered the owners or holders of the debt securities.

Principal, any premium and any interest payments on debt securities represented by a global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee as the registered owner of the global security. None of us, the Trustee or any paying agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the global security or maintaining, supervising or reviewing any records relating to the beneficial ownership interests.

27

Table of Contents

We expect that the depositary, upon receipt of any payments, will immediately credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global security as shown on the depositary’s records. We also expect that payments by participants to owners of beneficial interests in the global security will be governed by standing instructions and customary practices, as is the case with the securities held for the accounts of customers registered in “street names,” and will be the responsibility of the participants.

If the depositary is at any time unwilling or unable to continue as depositary and a successor depositary is not appointed by us within 90 days, we will issue registered securities in exchange for the global security. In addition, we may at any time in our sole discretion determine not to have any of the debt securities of a series represented by global securities. In that event, we will issue debt securities of that series in definitive form in exchange for the global securities.

DESCRIPTION OF THE WARRANTS

The following description of the terms of the warrants sets forth certain general terms and provisions of the warrants to which any prospectus supplement may relate. We may issue warrants for the purchase of common stock, preferred stock, or debt securities. Warrants may be issued independently or together with common stock, preferred stock, or debt securities offered by any prospectus supplement and may be attached to or separate from any such offered securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a bank or trust company, as warrant agent. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. The following summary of certain provisions of the warrants does not purport to be complete and is subject to, and qualified in its entirety by reference to, the provisions of the warrant agreement that will be filed with the SEC in connection with the offering of such warrants.

DESCRIPTION OF THE PURCHASE CONTRACTS

We may issue, from time to time, purchase contracts, including contracts obligating holders to purchase from us and us to sell to the holders, a specified principal amount of senior debt securities, subordinated debt securities, shares of common stock or preferred stock, government securities, or any of the other securities that we may sell under this prospectus at a future date or dates. The consideration payable upon settlement of the purchase contracts may be fixed at the time the purchase contracts are issued or may be determined by a specific reference to a formula set forth in the purchase contracts. The purchase contracts may be issued separately or as part of units consisting of a purchase contract and other securities or obligations issued by us or third parties, including United States treasury securities, securing the holders’ obligations to purchase the relevant securities under the purchase contracts. The purchase contracts may require us to make periodic payments to the holders of the purchase contracts or units or vice versa, and the payments may be unsecured or prefunded on some basis. The purchase contracts may require holders to secure their obligations under the purchase contracts.

The prospectus supplement related to any particular purchase contracts will describe, among other things, the material terms of the purchase contracts and of the securities being sold pursuant to such purchase contracts, a discussion, if appropriate, of any special United States federal income tax considerations applicable to the purchase contracts and any material provisions governing the purchase contracts that differ from those described above. The description in the prospectus supplement will not necessarily be complete and will be qualified in its entirety by reference to the purchase contracts, and, if applicable, collateral arrangements and depositary arrangements, relating to the purchase contracts.

DESCRIPTION OF THE 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 may also include debt obligations of third parties, such as U.S. Treasury securities. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each 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 prospectus supplement related to any particular units will describe, among other things:

SELLING STOCKHOLDERS

We may register shares of common stock covered by this prospectus for re-offers and resales by any selling stockholders named in a prospectus supplement filed with the Commission. We may register these shares to permit selling stockholders to resell their shares when they deem appropriate. Selling stockholders may resell all, a portion or none of their shares at any time and from time to time. Selling stockholders may also sell, transfer or otherwise dispose of some or all of their shares of our securities in transactions exempt from the registration requirements of the Securities Act. We do not know when or in what amounts the selling stockholders may offer shares for sale under this prospectus and any prospectus supplement. We may pay all expenses incurred with respect to the registration of the shares of common stock owned by the selling stockholders, other than underwriting fees, discounts or commissions, which will be borne by the selling stockholders. We will provide you with a prospectus supplement naming the selling stockholders, the amount of securities to be registered and sold and any other terms of the securities being sold by the selling stockholders.

PLAN OF DISTRIBUTION

We or the selling stockholders may offer and sell the securities in any one or more of the following ways:

In addition, we may enter into option, share lending or other types of transactions that require us to deliver shares of common stock to an underwriter, broker or dealer, who will then resell or transfer the shares of common stock under this prospectus. We may also enter into hedging transactions with respect to our securities.

Any selling stockholder will act independently of us in making decisions with respect to the timing, manner and size of each sale of shares of common stock covered by this prospectus.

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be identified in the applicable prospectus supplement (or a post-effective amendment). In addition, we may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

Shares of common stock may also be exchanged for satisfaction of the selling stockholders’ obligations or other liabilities to their creditors. Such transactions may or may not involve brokers or dealers.

Each time we or the selling stockholders sell securities, we will provide a prospectus supplement that will name any underwriter, dealer or agent involved in the offer and sale of the securities. The prospectus supplement will also set forth the terms of the offering, including:
