USE OF PROCEEDS

We intend to use the net proceeds from the sale of any securities offered under this prospectus for general corporate purposes unless otherwise indicated in the applicable prospectus supplement. General corporate purposes may include the acquisition of companies or businesses, repayment and refinancing of debt, working capital and capital expenditures.

Table of Contents

DESCRIPTION OF DEBT SECURITIES

We may offer debt securities which may be senior or subordinated. We refer to the senior debt securities and the subordinated debt securities collectively as debt securities. The following description summarizes the general terms and provisions of the debt securities. We will describe the specific terms of the debt securities and the extent, if any, to which the general provisions summarized below apply to any series of debt securities in the prospectus supplement relating to the series and any applicable free writing prospectus that we authorize to be delivered. In this description, the word "Casella" refers only to Casella Waste Systems, Inc. and not to any of its subsidiaries. You can find the definitions of certain terms used in this description under the subheading "—Certain Definitions."

We may issue senior debt securities from time to time, in one or more series under a senior indenture to be entered into between us and a senior trustee to be named in a prospectus supplement, which we refer to as the senior trustee. We may issue subordinated debt securities from time to time, in one or more series under a subordinated indenture to be entered into between us and a subordinated trustee to be named in a prospectus supplement, which we refer to as the subordinated trustee. The forms of senior indenture and subordinated indenture are filed as exhibits to this registration statement. Together, the senior indenture and the subordinated indenture are referred to as the indentures and, together, the senior trustee and the subordinated trustee are referred to as the trustees. This prospectus briefly outlines some of the provisions of the indentures. The following summary of the material provisions of the indentures is qualified in its entirety by the provisions of the indentures, including definitions of certain terms used in the indentures. Wherever we refer to particular sections or defined terms of the indentures, those sections or defined terms are incorporated by reference in this prospectus or the applicable prospectus supplement. You should review the indentures that are filed as exhibits to the registration statement of which this prospectus forms a part for additional information.

General

The senior debt securities will be:

•: general unsecured and unsubordinated obligations of Casella;
•: equal in right of payment to all existing and future Senior Debt of Casella;
•: effectively subordinated to the secured debt of Casella, including the Second Lien Notes, to the extent of the value of the collateral securing such debt;
•: senior in right of payment to any future Indebtedness of Casella that expressly provides that it is junior in right of payment to the senior debt securities, including the Senior Subordinated Notes; and
•: unconditionally guaranteed by the Guarantors.

Unless provided otherwise in the applicable prospectus supplement, the senior debt securities will be guaranteed by each existing and future Restricted Subsidiary of Casella, other than any Foreign Subsidiary, any Insurance Subsidiary and certain Restricted Subsidiaries of Casella that do not guarantee the Senior Credit Facility, the Second Lien Notes or, in each case, any Permitted Refinancing Indebtedness in respect thereof.

The Subsidiary Guarantee by each Guarantor will be:

•: a general unsecured and unsubordinated obligation of such Guarantor;
•: equal in right of payment to all existing and future Senior Debt of such Guarantor;

Table of Contents

•: effectively subordinated to the secured debt of each Guarantor, including the guarantees of the Second Lien Notes, to the extent of the value of the collateral securing such debt;
•: effectively subordinated to all of the liabilities, including trade payables, of Casella's Subsidiaries that are not providing a Subsidiary Guarantee;
•: senior in right of payment to all future senior subordinated Indebtedness of such Guarantor; and
•: senior in right of payment to all future Indebtedness of such Guarantor that expressly provides that it is junior in right of payment to the Subsidiary Guarantee of such Guarantor, including the guarantees of the Senior Subordinated Notes.

Unless the applicable prospectus supplement provide otherwise, all Subsidiaries will be "Restricted Subsidiaries." However, under certain circumstances, we will be permitted to designate certain of our subsidiaries as "Unrestricted Subsidiaries." Unrestricted Subsidiaries will not guarantee the senior debt securities or be subject to the restrictive covenants in the indenture, but transactions between Casella and/or any of its Restricted Subsidiaries on the one hand and any of the Unrestricted Subsidiaries on the other hand will be subject to certain restrictive covenants.

The applicable prospectus supplement and/or free writing prospectus will include any additional or different terms of the debt securities being offered, including the following terms:

•: the title and type of the debt securities;
•: whether the debt securities will be senior or subordinated debt securities, and, with respect to debt securities issued under the subordinated indenture the terms on which they are subordinated;
•: the aggregate principal amount of the debt securities;
•: the price or prices at which we will sell the debt securities;
•: the maturity date or dates of the debt securities and the right, if any, to extend such date or dates;
•: the rate or rates, if any, per year, at which the debt securities will bear interest, or the method of determining such rate or rates;
•: the date or dates from which such interest will accrue, the interest payment dates on which such interest will be payable or the manner of determination of such interest payment dates and the related record dates;
•: the right, if any, to extend the interest payment periods and the duration of that extension;
•: the manner of paying principal and interest and the place or places where principal and interest will be payable;
•: provisions for a sinking fund, purchase fund or other analogous fund, if any;
•: any redemption dates, prices, obligations and restrictions on the debt securities;
•: the currency, currencies or currency units in which the debt securities will be denominated and the currency, currencies or currency units in which principal and interest, if any, on the debt securities may be payable;
•: any conversion or exchange features of the debt securities;
•: whether and upon what terms the debt securities may be defeased;
•: any events of default or covenants in addition to or in lieu of those set forth in the indenture;

Table of Contents

•: whether the debt securities will be issued in definitive or global form or in definitive form only upon satisfaction of certain conditions;
•: whether the series of debt securities will be guaranteed as to payment or performance;
•: any special tax implications of the debt securities; and
•: any other material terms of the debt securities.

We may from time to time, without notice to or the consent of the holders of any series of debt securities, create and issue further debt securities of any such series ranking equally with the debt securities of such series in all respects (or in all respects other than (1) the payment of interest accruing prior to the issue date of such further debt securities or (2) the first payment of interest following the issue date of such further debt securities). Such further debt securities may be consolidated and form a single series with the debt securities of such series and have the same terms as to status, redemption or otherwise as the debt securities of such series.

Debt securities may bear interest at a fixed rate or a floating rate. Debt securities bearing no interest or interest at a rate that at the time of issuance is below the prevailing market rate (original issue discount securities) may be sold at a discount below their stated principal amount. U.S. federal income tax considerations applicable to any such discounted debt securities or to certain debt securities issued at par which are treated as having been issued at a discount for U.S. federal income tax purposes will be described in the applicable prospectus supplement.

We may issue debt securities with the principal amount payable on any principal payment date, or the amount of interest payable on any interest payment date, to be determined by reference to one or more currency exchange rates, securities or baskets of securities, commodity prices or indices. You may receive a payment of principal on any principal payment date, or a payment of interest on any interest payment date, that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending on the value on such dates of the applicable currency, security or basket of securities, commodity or index. Information as to the methods for determining the amount of principal or interest payable on any date, the currencies, securities or baskets of securities, commodities or indices to which the amount payable on such date is linked and certain related tax considerations will be set forth in the applicable prospectus supplement.

Certain Terms of the Senior Debt Securities

Transfer and Exchange

A Holder may transfer or exchange the senior debt securities in accordance with the indenture. The Registrar and the trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and Casella may require a Holder to pay any taxes and fees required by law or permitted by the indenture. The registered Holder of a senior debt security will be treated as the owner of it for all purposes.

Certain Covenants

Set forth below are summaries of certain covenants contained in the indenture.

Liens

Casella will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien of any kind securing Indebtedness, Attributable Debt or trade payables on any asset now owned or hereafter acquired, except Permitted Liens, unless all payments due under the indenture and the senior debt securities are secured on an equal and ratable basis with the obligation so secured until such time as such is no longer secured by a Lien; provided

Table of Contents

that if such obligation is by its terms expressly subordinated to the senior debt securities or any Subsidiary Guarantee, the Lien securing such obligation shall be subordinate and junior to the Lien securing the senior debt securities and the Subsidiary Guarantees with the same relative priority as such subordinate or junior obligation shall have with respect to the senior debt securities and the Subsidiary Guarantees.

Dividend and Other Payment Restrictions Affecting Subsidiaries

Casella will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:

(1): pay dividends or make any other distributions on or in respect of its Equity Interests to Casella or any of Casella's Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits, or pay any indebtedness owed to Casella or any of Casella's Restricted Subsidiaries;
(2): make loans or advances to Casella or any of Casella's Restricted Subsidiaries; or
(3): transfer any of its properties or assets to Casella or any of Casella's Restricted Subsidiaries.

(1): the Senior Credit Facility, the Second Lien Notes Documents or any Existing Indebtedness, in each case, as in effect on the Issue Date of any such series and any amendments or refinancings thereof; provided that such amendments or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other restrictions than those contained in the Senior Credit Facility, the Second Lien Notes Documents, the Senior Subordinated Notes Documents or such Existing Indebtedness, as applicable, as in effect on the date of the indenture;
(2): the indenture and the senior debt securities;
(3): applicable law, rule, regulation or order of any governmental authority;
(4): any instrument governing Indebtedness or Capital Stock of a Person acquired by Casella or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired;
(5): customary non-assignment provisions (and sublease restrictions) in leases entered into in the ordinary course of business and consistent with past practices;
(6): Purchase Money Obligations that impose restrictions only on the property acquired of the nature described in clause (3) of the preceding paragraph;
(7): any agreement for the sale or other disposition of a Restricted Subsidiary that restricts distributions by such Restricted Subsidiary pending its sale or other disposition;
(8): Permitted Refinancing Indebtedness; provided that such dividend and other restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced;

Table of Contents

(9): Liens securing Indebtedness otherwise permitted to be incurred pursuant to the provisions of the covenant described above under the caption "—Liens" that limit the right of Casella or any of its Restricted Subsidiaries to dispose of the assets subject to such Lien;
(10): provisions with respect to the disposition or distribution of assets or property in joint venture agreements (including, without limitation, agreements with respect to Restricted Subsidiaries that are not wholly owned) and other similar agreements entered into in the ordinary course of business;
(11): customary restrictions on cash or other deposits or net worth imposed by customers or government authorities under contracts or other agreements entered into in the ordinary course of business; and
(12): any agreement relating to a Sale and Leaseback Transaction, Purchase Money Obligation, industrial revenue bond or Capital Lease Obligation, in each case, otherwise not prohibited by the indenture, but only on the property subject to such transaction or lease and only to the extent that such restrictions or encumbrances are customary with respect to a Sale and Leaseback Transaction, Purchase Money Obligation, industrial revenue bond or capital lease.

Reports

Whether or not required by the SEC, so long as any senior debt securities are outstanding, Casella will furnish to the Holders of senior debt securities, within the time periods specified in the SEC's rules and regulations:

(1): all quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if Casella were required to file such Forms, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" and, with respect to the annual information only, a report on the annual financial statements by Casella's certified independent accountants; and
(2): all current reports that would be required to be filed with the SEC on Form 8-K if Casella were required to file such reports;

provided that any such above information or reports filed with the Electronic Data Gathering, Analysis and Retrieval ("EDGAR") system of the SEC (or successor system) and available publicly on the Internet shall be deemed to be furnished to the Holders of senior debt securities.

Also, Casella has agreed that, for so long as any senior debt securities remain outstanding, Casella will furnish to the Holders of senior debt securities, in each quarterly and annual report, the dollar amount of debt of Casella that would serve as the threshold for evaluating any entity that is a beneficial holder's compliance with the first paragraph under "Limitation on Ownership of Senior Debt Securities."

If Casella has designated any of its Subsidiaries as Unrestricted Subsidiaries, and the Unrestricted Subsidiaries taken as a whole account for at least 5.0% of the Consolidated EBITDA (calculated for Casella and its Subsidiaries, not just Restricted Subsidiaries) for the period of the most recent four consecutive fiscal quarters for which internal financial statements are available, of Casella and its Subsidiaries, taken as a whole, then the quarterly and annual financial information required by the preceding paragraph shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management's Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of Casella and its Restricted Subsidiaries separate from the financial condition and results of operations of Casella's Unrestricted Subsidiaries.

Table of Contents

In addition, whether or not required by the SEC, Casella will file a copy of all of the information and reports referred to in clauses (1) and (2) above with the SEC for public availability within the time periods specified in the SEC's rules and regulations (unless the SEC will not accept such a filing) and make such information available to securities analysts and prospective investors upon request. Casella agrees that it will not take any action for the purpose of causing the SEC not to accept such filings. If, notwithstanding the foregoing, the SEC will not accept such filings for any reason, Casella will post the reports specified in the preceding sentence on its website within the time periods that would apply if Casella were required to file those reports with the SEC.

Casella and the Guarantors have agreed that, for so long as any senior debt securities remain outstanding, Casella and the Guarantors will furnish to Holders of senior debt securities, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

(a): is caused by a failure to pay principal of or premium, if any, or interest on such Indebtedness prior to the expiration of the applicable grace period (a "Payment Default"); or
(b): results in the acceleration of such Indebtedness prior to its express maturity,

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $10.0 million or more;

(f): admits in writing its inability to pay its debts generally as they become due.

In the case of an Event of Default under clause (7) or (8) with respect to Casella or any Significant Subsidiary, all outstanding senior debt securities will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the trustee or the Holders of at least 25% in principal amount of the then outstanding senior debt securities may declare all the senior debt securities to be due and payable immediately.

Holders of the senior debt securities may not enforce the indenture or the senior debt securities except as provided in the indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding senior debt securities may direct the trustee in its exercise of any trust or power. The trustee may withhold from Holders of the senior debt securities notice of any continuing Default (except a Default relating to the payment of principal or interest) if it determines that withholding notice is in their interest.

The Holders of a majority in aggregate principal amount of a series of senior debt securities then outstanding by notice to the trustee may on behalf of the Holders of all of the senior debt securities of such series waive any existing Default and its consequences under the indenture except a continuing Default in the payment of interest on, or the principal or premium of, the senior debt securities of such series.

Casella is required to deliver to the trustee annually a statement regarding compliance with the indenture. Upon becoming aware of any Default, Casella is required to deliver to the trustee a statement specifying such Default.

No Personal Liability of Directors, Officers, Employees and Stockholders

No director, officer, employee, incorporator or stockholder of Casella or any Guarantor, as such, shall have any liability for any obligations of Casella or the Guarantors under the senior debt securities,

Table of Contents

the indenture, the Guarantors' Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of senior debt securities by accepting a senior debt security waives and releases all such liability. The waiver and release are part of the consideration for issuance of the senior debt securities. The waiver may not be effective to waive liabilities under the federal securities laws.

Legal Defeasance and Covenant Defeasance

Casella may, at its option and at any time, elect to have all of its Obligations discharged with respect to any series of outstanding senior debt securities and the indenture, and all Obligations of the Guarantors discharged with respect to their related Subsidiary Guarantees ("Legal Defeasance") except for:

(1): the rights of Holders of such outstanding senior debt securities to receive payments in respect of the principal of, premium, if any, and interest on such senior debt securities when such payments are due from the trust referred to below;
(2): Casella's obligations with respect to such senior debt securities concerning issuing temporary senior debt securities, registration of senior debt securities, mutilated, destroyed, lost or stolen senior debt securities and the maintenance of an office or agency for payment and money for security payments held in trust;
(3): the rights, powers, trusts, duties and immunities of the trustee, and Casella's obligations in connection therewith; and
(4): the Legal Defeasance provisions of the indenture.

In addition, Casella may, at its option and at any time, and with respect to any series of outstanding senior debt securities elect to have the obligations of Casella and the Guarantors released with respect to certain covenants that are described in the indenture ("Covenant Defeasance") and thereafter any omission to comply with those covenants shall not constitute a Default with respect to such senior debt securities. In the event Covenant Defeasance occurs, (i) any event described in clauses (3), (4), (5) or (6) of the definition of "Event of Default" will no longer constitute an Event of Default with respect to such senior debt securities and (ii) any event described in clauses (1), (2), (7) or (8) of the definition of "Event of Default" will continue to constitute an Event of Default with respect to the senior debt securities.

In order to exercise either Legal Defeasance or Covenant Defeasance:

(1): Casella must irrevocably deposit with the trustee, in trust, for the benefit of the Holders of the applicable series of senior debt securities, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest on such outstanding senior debt securities on the Stated Maturity or on the applicable redemption date, as the case may be, and Casella must specify whether such senior debt securities are being defeased to maturity or to a particular redemption date;
(2): in the case of Legal Defeasance, Casella shall have delivered to the trustee an Opinion of Counsel reasonably acceptable to the trustee confirming that (a) Casella has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the date of the indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of such outstanding senior debt securities will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal

Table of Contents

income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3): in the case of Covenant Defeasance, Casella shall have delivered to the trustee an Opinion of Counsel reasonably acceptable to the trustee confirming that the Holders of such outstanding senior debt securities will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;
(4): no Default shall have occurred and be continuing either: (a) on the date of such deposit (other than a Default resulting from the borrowing of funds to be applied to such deposit), or (b) insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit; provided that such Legal Defeasance or Covenant Defeasance, as the case may be, shall be deemed to have occurred on the date of such deposit, subject to an Event of Default from bankruptcy or insolvency within such 91-day period;
(5): such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than the indenture) to which Casella or any of its Restricted Subsidiaries is a party or by which Casella or any of its Restricted Subsidiaries is bound;
(6): Casella must deliver to the trustee an Officers' Certificate stating that the deposit was not made by Casella with the intent of preferring the Holders of senior debt securities over the other creditors of Casella with the intent of defeating, hindering, delaying or defrauding creditors of Casella or others; and
(7): Casella must deliver to the trustee an Officers' Certificate and an Opinion of Counsel stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Amendment, Supplement and Waiver

Casella and the Guarantors, when authorized by board resolutions, and the trustee may enter into one or more supplemental indentures to amend the indenture or any series of senior debt securities with the written consent of Holders of a majority of the principal amount of the then outstanding senior debt securities of such series. The Holders of a majority in principal amount of then outstanding senior debt securities of any series may waive any existing Default or compliance with any provision of the indenture or such senior debt securities without prior notice to any holder of senior debt securities.

Notwithstanding the foregoing, without the consent of each Holder affected, an amendment or waiver may not (with respect to any senior debt securities held by a non-consenting Holder):

(1): reduce the principal amount of senior debt securities of any series whose Holders must consent to an amendment, supplement or waiver;
(2): reduce the principal of or change or have the effect of changing the fixed maturity of any senior debt security or alter the provisions with respect to the redemption of the senior debt securities;
(3): reduce the rate of or change the time for payment of interest on any senior debt security;
(4): waive an uncured Default in the payment of principal of or premium, if any, or interest on the senior debt securities (except a rescission of acceleration of the senior debt securities by the

Table of Contents

Holders of at least a majority in aggregate principal amount of the senior debt securities of the affected series and a waiver of the payment default that resulted from such acceleration);

(5): make any senior debt security payable in money other than that stated in such senior debt security;
(6): impair or affect the right of any Holder of senior debt securities to receive payment of principal of and interest on such senior debt securities on or after the due dates therefor or to institute suit for payment for the enforcement of any such payment on or after the due dates therefor, or make any changes in the provisions of the indenture permitting Holders of a majority in principal amount of any series senior debt securities to waive any past Default and its consequences;
(7): waive a redemption payment with respect to any senior debt securities;
(8): release any Guarantor from any of its obligations under its Subsidiary Guarantee or the indenture otherwise than in accordance with the terms of the indenture;
(9): make any change in the preceding amendment and waiver provisions.

Notwithstanding the foregoing, without the consent of or prior notice to any Holder of senior debt securities, Casella and the trustee may amend or supplement the indenture or the senior debt securities:

(1): to cure any ambiguity, defect or inconsistency;
(2): to provide for uncertificated senior debt securities in addition to or in place of certificated senior debt securities;
(3): to provide for the assumption of Casella's obligations to Holders of senior debt securities in the case of a merger or consolidation or sale of all or substantially all of Casella's assets;
(4): to make any change that would provide any additional rights or benefits to the Holders of senior debt securities or that does not adversely affect the legal rights under the indenture of any Holder;
(5): to comply with requirements of the SEC in order to effect or maintain the qualification of the indenture under the Trust Indenture Act; or
(6): to evidence and provide for the acceptance of appointment under the indenture by a successor or replacement trustee.

The consent of Holders of the senior debt securities is not necessary under the indenture to approve the particular form of any proposed amendment; it is sufficient if such consent approves the substance of the proposed amendment.

After an amendment under the indenture becomes effective, Casella is required to mail to the applicable Holders a notice briefly describing such amendment. However, the failure to give such notice to all Holders entitled to receive such notice, or any defect therein, will not impair or affect the validity of the amendment.

Limitation on Ownership of Senior Debt Securities

Unless provided otherwise in the applicable prospectus supplement, the indenture will require that each entity that is a beneficial holder of senior debt securities not knowingly acquire senior debt securities such that, after giving effect thereto, such entity owns 10% or more of the consolidated debt of Casella for which relevant subsidiaries of Casella are obligated (and to dispose of senior debt securities or other debt of Casella to the extent such entity becomes aware of exceeding such threshold), if such ownership would require consent of any regulatory authority under applicable law or regulation governing solid waste operators and such consent has not been obtained.

Table of Contents

Casella and each Guarantor will use commercially reasonable efforts to obtain the consent, permit modification, exemption or other relief necessary for any entity that is a beneficial holder or potential beneficial holder of senior debt securities to exceed any applicable debt ownership level under any applicable law or regulation promptly following written request by such entity that is a beneficial holder or potential beneficial holder (provided that such entity that is a beneficial holder or potential beneficial holder would qualify as an eligible or suitable holder under such law or regulation); provided, however, that nothing in this paragraph shall affect the provisions of the prior paragraph requiring a beneficial holder to dispose of senior debt securities or other debt if such consent has not been obtained and the failure to have such consent would constitute a violation of applicable law or regulation.

Governing Law

The indenture, the senior debt securities and the Subsidiary Guarantees will be governed by the laws of the State of New York.

Certain Terms of the Subordinated Debt Securities

Other than the terms of the subordinated indenture and subordinated debt securities relating to subordination or otherwise as described in the prospectus supplement relating to a particular series of subordinated debt securities, the terms of the subordinated indenture and subordinated debt securities are identical in all material respects to the terms of the senior indenture and senior debt securities.

Additional or different subordination terms may be specified in the prospectus supplement applicable to a particular series.

The payment of all Obligations on or relating to any series of the subordinated debt securities is subordinated in right of payment to the prior payment in full in cash or cash equivalents of all Obligations on Senior Debt of Casella (including all Obligations with respect to the Senior Credit Facility and all obligations with respect to the Second Lien Notes, whether outstanding on the Issue Date for such series or thereafter incurred). Notwithstanding the foregoing, payments and distributions made from the trust established pursuant to the provisions described under "—Legal Defeasance and Covenant Defeasance" shall not be so subordinated in right of payment so long as the payments into the trust were made in accordance with the requirements described under "—Legal Defeasance and Covenant Defeasance" and did not violate the subordination provisions when they were made.

The Subsidiary Guarantee of each Guarantor of the subordinated debt securities will be subordinated to the prior payment in full in cash or cash equivalents of all Senior Debt of that Guarantor to the same extent that the subordinated debt securities are subordinated to Senior Debt of Casella.

The holders of Senior Debt will be entitled to receive payment in full in cash or cash equivalents of all Obligations due in respect of Senior Debt before the Holders of any series of subordinated debt securities will be entitled to receive any payment or distribution of any kind or character with respect to any Obligations on, or relating to, such series of the subordinated debt securities (other than payments or distributions of Permitted Junior Securities) in the event of any distribution to creditors of Casella:

(1): in a total or partial liquidation, dissolution or winding up of Casella;
(2): in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to Casella or its assets;
(3): in an assignment for the benefit of creditors; or
(4): in any marshalling of Casella's assets and liabilities.

Table of Contents

As a result of the subordination provisions described above, in the event of a bankruptcy, liquidation or reorganization of Casella, Holders of subordinated debt securities may recover less ratably than creditors of Casella who are holders of Senior Debt.

(2): if interest on any Indebtedness actually incurred on the Transaction Date may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rates, then the interest rate in effect on the Transaction Date will be deemed to have been in effect during the Four Quarter Period; and
(3): notwithstanding clause (1) above, interest on Indebtedness determined on a fluctuating basis, to the extent such interest is covered by agreements relating to Hedging Obligations, shall be deemed to accrue at the weighted average rate per annum during the Four Quarter Period resulting after giving effect to the operation of such agreements.

DESCRIPTION OF CAPITAL STOCK

The following description of our capital stock is intended as a summary only. This description is based upon, and is qualified by reference to, our certificate of incorporation, our by-laws and applicable provisions of Delaware corporate law. This summary is not complete. You should read our certificate of incorporation and by-laws, which are filed as exhibits to the registration statement of which this prospectus forms a part, for the provisions that are important to you.

Our authorized capital stock consists of 100,000,000 shares of class A common stock, 1,000,000 shares of class B common stock and 944,250 shares of preferred stock. As of August 25, 2011, 25,898,225 shares of class A common stock were outstanding, 988,200 shares of class A common stock were issuable upon the conversion of outstanding shares of class B common stock, and no shares of preferred stock were outstanding. The only common stock that we would offer under this prospectus is class A common stock.

Common Stock

Annual Meeting. Annual meetings of our stockholders are held on the date designated in accordance with our by-laws. Written notice must be mailed to each stockholder entitled to vote not less than ten nor more than 60 days before the date of the meeting. The presence in person or by proxy of the holders of record of a majority of our issued and outstanding shares entitled to vote at such meeting constitutes a quorum for the transaction of business at meetings of the stockholders. Special meetings of the stockholders may be called for any purpose by the chief executive officer or the chairman of the board of directors. Except as may be otherwise provided by applicable law, our restated certificate of incorporation or our by-laws, all elections shall be decided by a plurality, and all other questions shall be decided by a majority, of the votes cast by stockholders entitled to vote thereon at a duly held meeting of stockholders at which a quorum is present.

Voting Rights. On all matters submitted to a vote of our stockholders, the holders of our class A common stock are entitled to one vote per share, and the holders of our class B common stock are entitled to ten votes per share. The holders of all classes of our common stock entitled to vote will generally vote together as a single class on all matters presented to the stockholders for their vote or approval, except that the holders of class A common stock, voting separately as a class, will at all times be entitled to elect one director, and such director may be removed, with or without cause, only by the holders of our class A common stock.

Dividends. The holders of our class A common stock and class B common stock are entitled to receive dividends if, as and when such dividends are declared by our board of directors out of assets legally available therefor, subject to any preferential rights of our preferred stock, if any. We may not make any dividend or distribution to any holder of any class of our common stock unless simultaneously with such dividend or distribution we make the same dividend or distribution with respect to each outstanding share of our common stock regardless of class. In the case of a dividend or other distribution payable in shares of a class of our common stock, including distributions pursuant to stock splits or divisions of common stock, only shares of our class A common stock may be distributed with respect to class A common stock, and only shares of our class B common stock may be distributed with respect to class B common stock. Whenever a dividend or distribution, including distributions pursuant to stock splits or divisions of common stock, is payable in shares of a class of common stock, the number of shares of each class of common stock payable per share of such class of common stock shall be equal in number. In the case of dividends or other distributions consisting of our other voting securities or of voting securities of any corporation which is a wholly-owned subsidiary of ours, we shall

Table of Contents

declare and pay such dividends in two separate classes of such voting securities, identical in all respects except that:

•: the voting rights of each such security issued to the holders of class A common stock shall be one-tenth of the voting rights of each such security issued to holders of class B common stock;
•: such security issued to holders of class B common stock shall convert into the security issued to the holders of class A common stock upon the same terms and conditions applicable to the conversion of class B common stock into class A common stock and shall have the same restrictions on transfer and ownership applicable to the transfer and ownership of our class B common stock; and
•: with respect only to dividends or other distributions of voting securities of any corporation which is a wholly owned subsidiary of ours, the respective voting rights of each such security issued to holders of class A common stock and class B common stock with respect to elections of directors shall otherwise be as comparable as is practicable to those of our class A common stock and class B common stock, respectively.

In the case of dividends or other distributions consisting of securities convertible into, or exchangeable for, our voting securities or of voting securities of any corporation which is a wholly owned subsidiary of ours, we are required to provide that such convertible or exchangeable securities and the underlying securities are identical in all respects, including, without limitation, the conversion or exchange rate, except that the underlying securities shall have the same differences as they would have if we issued voting securities of ours or of a wholly-owned subsidiary of ours rather than issuing securities convertible into, or exchangeable for, such securities.

Reclassification and Merger. In the event we enter into any consolidation, merger, combination or other transaction in which shares of our common stock are exchanged for or changed into other stock or securities, cash and/or any other property, then, and in such event, the shares of each class of our common stock will be exchanged for or changed into either:

•: the same amount of stock, securities, cash and/or any other property, as the case may be, into which or for which each share of any other class of common stock is exchanged or changed; provided, however, that if shares of common stock are exchanged for or changed into shares of capital stock, such share so exchanged for or changed into may differ to the extent and only to the extent that our class A common stock and class B common stock differ as provided in our certificate of incorporation; or
•: if holders of each class of common stock are to receive different distributions of stock, securities, cash and/or any other property, an amount of stock, securities, cash and/or property per share having a value, as determined by an independent investment banking firm of national reputation selected by our board of directors, equal to the value per share into which or for which each share of any other class of common stock is exchanged or changed.

Liquidation and Dissolution. In the event of our liquidation, dissolution or winding up, whether voluntary or involuntary, after payment or provision for payment of our debts and our other liabilities and after making provision for the holders of our preferred stock, if any, our remaining assets and funds, if any, will be divided among and paid ratably to the holders of our class A common stock and class B common stock treated as a single class.

Other Rights. The holders of our class A common stock and class B common stock are not entitled to preemptive rights. None of the class A common stock or class B common stock may be subdivided or combined in any manner unless the other class of common stock is subdivided or combined in the same proportion. We may not make any offering of options, rights or warrants to subscribe for shares of class B common stock. If we make an offering of options, rights or warrants to

Table of Contents

subscribe for shares of any other class or classes of capital stock (other than class B common stock) to all holders of a class of common stock, then we are required to simultaneously make an identical offering to all holders of the other classes of common stock other than to any class the holders of which, voting as a separate class, agree that such offering need not be made to such class. All such options, rights or warrants offerings shall offer the respective holders of class A common stock and class B common stock the right to subscribe at the same rate per share.

Transfer Agent and Registrar. Computershare is transfer agent and registrar for the Class A common stock.

Preferred Stock

As of August 25, 2011, no shares of preferred stock were outstanding. Other terms of any series of preferred stock will be described in the prospectus supplement relating to that series of preferred stock. The terms of any series of preferred stock may differ from the terms described below. Certain provisions of the preferred stock described below and in any applicable prospectus supplement are not complete.

We are authorized to issue "blank check" preferred stock, which may be issued in one or more series upon authorization of our board of directors. Our board of directors is authorized to fix the designation of the series, the number of authorized shares of the series, dividend rights and terms, conversion rights, voting rights, redemption rights and terms, liquidation preferences and any other rights, powers, preferences and limitations applicable to each series of preferred stock. The authorized shares of our preferred stock are available for issuance without further action by our stockholders, unless such action is required by applicable law or the rules of any stock exchange on which our securities may be listed. If the approval of our stockholders is not required for the issuance of shares of our preferred stock, our board may determine not to seek stockholder approval.

A series of our preferred stock could, depending on the terms of such series, impede the completion of a merger, tender offer or other takeover attempt. Our board of directors will make any determination to issue such shares based upon its judgment as to the best interests of our stockholders. Our directors, in so acting, could issue preferred stock having terms that could discourage an acquisition attempt through which an acquirer may be able to change the composition of our board of directors, including a tender offer or other transaction that some, or a majority, of our stockholders might believe to be in their best interests or in which stockholders might receive a premium for their stock over the then-current market price of the stock.

The preferred stock has the terms described below unless otherwise provided in the prospectus supplement relating to a particular series of preferred stock. You should read the prospectus supplement relating to the particular series of preferred stock being offered for specific terms, including:

•: the designation and stated value per share of the preferred stock and the number of shares offered;
•: the amount of liquidation preference per share;
•: the price at which the preferred stock will be issued;
•: the dividend rate, or method of calculation of dividends, the dates on which dividends will be payable, whether dividends will be cumulative or noncumulative and, if cumulative, the dates from which dividends will commence to accumulate;
•: any redemption or sinking fund provisions;

Table of Contents

•: if other than the currency of the United States, the currency or currencies including composite currencies in which the preferred stock is denominated and/or in which payments will or may be payable;
•: any conversion provisions;
•: whether we have elected to offer depositary shares as described under "Description of Depositary Shares;" and
•: any other rights, preferences, privileges, limitations and restrictions on the preferred stock.

The preferred stock will, when issued, be fully paid and nonassessable. Unless otherwise specified in the prospectus supplement, each series of preferred stock will rank equally as to dividends and liquidation rights in all respects with each other series of preferred stock. The rights of holders of shares of each series of preferred stock will be subordinate to those of our general creditors.

As described under "Description of Depositary Shares," we may, at our option, with respect to any series of preferred stock, elect to offer fractional interests in shares of preferred stock, and provide for the issuance of depositary receipts representing depositary shares, each of which will represent a fractional interest in a share of the series of preferred stock. The fractional interest will be specified in the prospectus supplement relating to a particular series of preferred stock.

Rank. Unless otherwise specified in the prospectus supplement, the preferred stock will, with respect to dividend rights and rights upon our liquidation, dissolution or winding up of its affairs, rank:

•: senior to our common stock and to all equity securities ranking junior to such preferred stock with respect to dividend rights or rights upon our liquidation, dissolution or winding up of our affairs;
•: on a parity with all equity securities issued by us, the terms of which specifically provide that such equity securities rank on a parity with the preferred stock with respect to dividend rights or rights upon our liquidation, dissolution or winding up of our affairs; and
•: junior to all equity securities issued by us, the terms of which specifically provide that such equity securities rank senior to the preferred stock with respect to dividend rights or rights upon our liquidation, dissolution or winding up of our affairs.

The term "equity securities" does not include convertible debt securities.

Dividends. Holders of the preferred stock of each series will be entitled to receive, when, as and if declared by our board of directors, cash dividends at such rates and on such dates described in the prospectus supplement. Different series of preferred stock may be entitled to dividends at different rates or based on different methods of calculation. The dividend rate may be fixed or variable or both. Dividends will be payable to the holders of record as they appear on our stock books on record dates fixed by our board of directors, as specified in the applicable prospectus supplement.

Dividends on any series of preferred stock may be cumulative or noncumulative, as described in the applicable prospectus supplement. If our board of directors does not declare a dividend payable on a dividend payment date on any series of noncumulative preferred stock, then the holders of that noncumulative preferred stock will have no right to receive a dividend for that dividend payment date, and we will have no obligation to pay the dividend accrued for that period, whether or not dividends on that series are declared payable on any future dividend payment dates. Dividends on any series of cumulative preferred stock will accrue from the date we initially issue shares of such series or such other date specified in the applicable prospectus supplement.

Table of Contents

No dividends may be declared or paid or funds set apart for the payment of any dividends on any parity securities unless full dividends have been paid or set apart for payment on the preferred stock. If full dividends are not paid, the preferred stock will share dividends pro rata with the parity securities.

No dividends may be declared or paid or funds set apart for the payment of dividends on any junior securities unless full dividends for all dividend periods terminating on or prior to the date of the declaration or payment will have been paid or declared and a sum sufficient for the payment set apart for payment on the preferred stock.

Liquidation Preference. Upon any voluntary or involuntary liquidation, dissolution or winding up of our affairs, then, before we make any distribution or payment to the holders of any common stock or any other class or series of our capital stock ranking junior to the preferred stock in the distribution of assets upon any liquidation, dissolution or winding up of our affairs, the holders of each series of preferred stock shall be entitled to receive out of assets legally available for distribution to stockholders, liquidating distributions in the amount of the liquidation preference per share set forth in the prospectus supplement, plus any accrued and unpaid dividends thereon. Such dividends will not include any accumulation in respect of unpaid noncumulative dividends for prior dividend periods. Unless otherwise specified in the prospectus supplement, after payment of the full amount of their liquidating distributions, the holders of preferred stock will have no right or claim to any of our remaining assets. Upon any such voluntary or involuntary liquidation, dissolution or winding up, if our available assets are insufficient to pay the amount of the liquidating distributions on all outstanding preferred stock and the corresponding amounts payable on all other classes or series of our capital stock ranking on parity with the preferred stock and all other such classes or series of shares of capital stock ranking on parity with the preferred stock in the distribution of assets, then the holders of the preferred stock and all other such classes or series of capital stock will share ratably in any such distribution of assets in proportion to the full liquidating distributions to which they would otherwise be entitled.

Upon any such liquidation, dissolution or winding up and if we have made liquidating distributions in full to all holders of preferred stock, we will distribute our remaining assets among the holders of any other classes or series of capital stock ranking junior to the preferred stock according to their respective rights and preferences and, in each case, according to their respective number of shares. For such purposes, our consolidation or merger with or into any other corporation, trust or entity, or the sale, lease or conveyance of all or substantially all of our property or assets will not be deemed to constitute a liquidation, dissolution or winding up of our affairs.

Redemption. If so provided in the applicable prospectus supplement, the preferred stock will be subject to mandatory redemption or redemption at our option, as a whole or in part, in each case upon the terms, at the times and at the redemption prices set forth in such prospectus supplement.

The prospectus supplement relating to a series of preferred stock that is subject to mandatory redemption will specify the number of shares of preferred stock that shall be redeemed by us in each year commencing after a date to be specified, at a redemption price per share to be specified, together with an amount equal to all accrued and unpaid dividends thereon to the date of redemption. Unless the shares have a cumulative dividend, such accrued dividends will not include any accumulation in respect of unpaid dividends for prior dividend periods. We may pay the redemption price in cash or other property, as specified in the applicable prospectus supplement. If the redemption price for preferred stock of any series is payable only from the net proceeds of the issuance of shares of our capital stock, the terms of such preferred stock may provide that, if no such shares of our capital stock shall have been issued or to the extent the net proceeds from any issuance are insufficient to pay in full the aggregate redemption price then due, such preferred stock shall automatically and mandatorily be converted into the applicable shares of our capital stock pursuant to conversion provisions specified in

Table of Contents

the applicable prospectus supplement. Notwithstanding the foregoing, we will not redeem any preferred stock of a series unless:

•: if that series of preferred stock has a cumulative dividend, we have declared and paid or contemporaneously declare and pay or set aside funds to pay full cumulative dividends on the preferred stock for all past dividend periods and the then current dividend period; or
•: if such series of preferred stock does not have a cumulative dividend, we have declared and paid or contemporaneously declare and pay or set aside funds to pay full dividends for the then current dividend period.

In addition, we will not acquire any preferred stock of a series unless:

•: if that series of preferred stock has a cumulative dividend, we have declared and paid or contemporaneously declare and pay or set aside funds to pay full cumulative dividends on all outstanding shares of such series of preferred stock for all past dividend periods and the then current dividend period; or
•: if that series of preferred stock does not have a cumulative dividend, we have declared and paid or contemporaneously declare and pay or set aside funds to pay full dividends on the preferred stock of such series for the then current dividend period.

However, at any time we may purchase or acquire preferred stock of that series (1) pursuant to a purchase or exchange offer made on the same terms to holders of all outstanding preferred stock of such series or (2) by conversion into or exchange for shares of our capital stock ranking junior to the preferred stock of such series as to dividends and upon liquidation.

If fewer than all of the outstanding shares of preferred stock of any series are to be redeemed, we will determine the number of shares that may be redeemed pro rata from the holders of record of such shares in proportion to the number of such shares held or for which redemption is requested by such holder or by any other equitable manner that we determine. Such determination will reflect adjustments to avoid redemption of fractional shares.

Unless otherwise specified in the prospectus supplement, we will mail notice of redemption at least 30 days but not more than 60 days before the redemption date to each holder of record of preferred stock to be redeemed at the address shown on our stock transfer books. Each notice shall state:

•: the redemption date;
•: the number of shares and series of preferred stock to be redeemed;
•: the redemption price;
•: the place or places where certificates for such preferred stock are to be surrendered for payment of the redemption price;
•: that dividends on the shares to be redeemed will cease to accrue on such redemption date;
•: the date on which the holder's conversion rights, if any, as to such shares shall terminate; and
•: the specific number of shares to be redeemed from each such holder if fewer than all the shares of any series are to be redeemed.

If notice of redemption has been given and we have set aside the funds necessary for such redemption in trust for the benefit of the holders of any shares called for redemption, then from and after the redemption date, dividends will cease to accrue on such shares, and all rights of the holders of such shares will terminate, except the right to receive the redemption price.

Table of Contents

Voting Rights. Holders of preferred stock will not have any voting rights, except as required by law or as indicated in the applicable prospectus supplement.

Unless otherwise provided for under the terms of any series of preferred stock, no consent or vote of the holders of shares of preferred stock or any series thereof shall be required for any amendment to our certificate of incorporation that would increase the number of authorized shares of preferred stock or the number of authorized shares of any series thereof or decrease the number of authorized shares of preferred stock or the number of authorized shares of any series thereof (but not below the number of authorized shares of preferred stock or such series, as the case may be, then outstanding).

Conversion Rights. The terms and conditions, if any, upon which any series of preferred stock is convertible into our common stock will be set forth in the applicable prospectus supplement relating thereto. Such terms will include the number of shares of common stock into which the shares of preferred stock are convertible, the conversion price, rate or manner of calculation thereof, the conversion period, provisions as to whether conversion will be at our option or at the option of the holders of the preferred stock, the events requiring an adjustment of the conversion price and provisions affecting conversion in the event of the redemption.

Transfer Agent and Registrar. The transfer agent and registrar for the preferred stock will be set forth in the applicable prospectus supplement.

Provisions of Our Certificate of Incorporation and By-laws and Delaware Law That May Have Anti-Takeover Effects

Board of Directors. Our certificate of incorporation and by-laws provide for the division of our board of directors into three classes as nearly equal in size as possible, with no class having more than one director more than any other class, with staggered three-year terms. The director nominated by holders of our class A common stock and elected to office is a class I director. Our certificate of incorporation and by-laws provide that directors may be removed with or without cause by the vote of the holders of shares representing at least 75% of the votes which all of our stockholders would be entitled to cast at any election of directors, other than an election of the class A director. The class A director may be removed only by the holders of at least 75% of the outstanding shares of our class A common stock. Moreover, our certificate of incorporation and by-laws provide that any vacancy on the board of directors, however occurring, including a vacancy resulting from an enlargement of the board, may only be filled by vote of a majority of the directors then in office. The term of any director elected to fill a vacancy between annual meetings will last until the next annual meeting and until such director's successor has been elected and qualified, or until his earlier death, resignation or removal. The classification of our board of directors and the limitations on the removal of directors and filling of vacancies could have the effect of making it more difficult for a third party to acquire, or discourage a third party from acquiring, us.

Removal of Directors by Stockholders. Delaware law provides that members of our board of directors may only be removed for cause by a vote of the holders of a majority of the outstanding shares entitled to vote on the election of the directors.

Stockholder Nomination of Directors. Our by-laws provide that a stockholder must notify us in writing of any stockholder nomination of a director not earlier than the 120^th day and not later than the 90^th day prior to the first anniversary of the preceding year's annual meeting; provided, that if the date of the annual meeting is advanced by more than 20 days, or delayed by more than 60 days from such anniversary date, notice by the stockholder to be timely must be so delivered not earlier than the 120^th day prior to the date of such annual meeting and not later than the close of business on the later of (x) the 90^th day prior to the date of such meeting and (y) the 10^th day following the day on which

Table of Contents

notice of the date such annual meeting was mailed or public disclosure of the date of such annual meeting was made, whichever occurs first.

No Action By Written Consent. Our restated certificate of incorporation provides that our stockholders may not act by written consent and may only act at duly called meetings of stockholders.

Delaware Business Combination Statute. Section 203 of the General Corporation Law of the State of Delaware, which we refer to as the DGCL, is applicable to us, Section 203 of the DGCL restricts some types of transactions and business combinations between a corporation and a 15% stockholder. A 15% stockholder is generally considered by Section 203 to be a person owning 15% or more of the corporation's outstanding voting stock. Section 203 refers to a 15% stockholder as an "interested stockholder." Section 203 restricts these transactions for a period of three years from the date the stockholder acquires 15% or more of our outstanding voting stock. With some exceptions, unless the transaction is approved by the board of directors and the holders of at least two-thirds of the outstanding voting stock of the corporation, Section 203 prohibits significant business transactions such as:

•: a merger with, disposition of significant assets to or receipt of disproportionate financial benefits by the interested stockholder, and
•: any other transaction that would increase the interested stockholder's proportionate ownership of any class or series of our capital stock.

The shares held by the interested stockholder are not counted as outstanding when calculating the two-thirds of the outstanding voting stock needed for approval.

The prohibition against these transactions does not apply if:

•: prior to the time that any stockholder became an interested stockholder, the board of directors approved either the business combination or the transaction in which such stockholder acquired 15% or more of our outstanding voting stock, or
•: the interested stockholder owns at least 85% of our outstanding voting stock as a result of a transaction in which such stockholder acquired 15% or more of our outstanding voting stock. Shares held by persons who are both directors and officers or by some types of employee stock plans are not counted as outstanding when making this calculation.

Directors' Liability

Our certificate of incorporation provides that a member of the board of directors will not be personally liable to us or our stockholders for monetary damages for breaches of their legal duties to us or our stockholders as a director, except to the extent that the General Corporation Law of Delaware prohibits the elimination or limitation of liability of directors for breaches of fiduciary duty.

Our certificate of incorporation also allows us to indemnify directors and officers to the fullest extent authorized by Delaware law.

DESCRIPTION OF DEPOSITARY SHARES

General

We may, at our option, elect to offer fractional shares of preferred stock, which we call depositary shares, rather than full shares of preferred stock. If we do, we will issue to the public receipts, called depositary receipts, for depositary shares, each of which will represent a fraction, to be described in the applicable prospectus supplement, of a share of a particular series of preferred stock. Unless otherwise provided in the prospectus supplement, each owner of a depositary share will be entitled, in proportion to the applicable fractional interest in a share of preferred stock represented by the depositary share, to all the rights and preferences of the preferred stock represented by the depositary share. Those rights include dividend, voting, redemption, conversion and liquidation rights.

The shares of preferred stock underlying the depositary shares will be deposited with a bank or trust company selected by us to act as depositary under a deposit agreement between us, the depositary and the holders of the depositary receipts. The depositary will be the transfer agent, registrar and dividend disbursing agent for the depositary shares.

The depositary shares will be evidenced by depositary receipts issued pursuant to the depositary agreement. Holders of depositary receipts agree to be bound by the deposit agreement, which requires holders to take certain actions such as filing proof of residence and paying certain charges.

The summary of terms of the depositary shares contained in this prospectus is not complete. You should refer to the form of the deposit agreement, our certificate of incorporation and the certificate of designation for the applicable series of preferred stock that are, or will be, filed with the SEC.

Dividends and Other Distributions

The depositary will distribute all cash dividends or other cash distributions, if any, received in respect of the preferred stock underlying the depositary shares to the record holders of depositary shares in proportion to the numbers of depositary shares owned by those holders on the relevant record date. The relevant record date for depositary shares will be the same date as the record date for the underlying preferred stock.

If there is a distribution other than in cash, the depositary will distribute property (including securities) received by it to the record holders of depositary shares, unless the depositary determines that it is not feasible to make the distribution. If this occurs, the depositary may, with our approval, adopt another method for the distribution, including selling the property and distributing the net proceeds from the sale to the holders.

Liquidation Preference

If a series of preferred stock underlying the depositary shares has a liquidation preference, in the event of the voluntary or involuntary liquidation, dissolution or winding up of us, holders of depositary shares will be entitled to receive the fraction of the liquidation preference accorded each share of the applicable series of preferred stock, as set forth in the applicable prospectus supplement.

Withdrawal of Stock

Unless the related depositary shares have been previously called for redemption, upon surrender of the depositary receipts at the office of the depositary, the holder of the depositary shares will be entitled to delivery, at the office of the depositary to or upon his or her order, of the number of whole shares of the preferred stock and any money or other property represented by the depositary shares. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole shares of preferred stock to be

Table of Contents

withdrawn, the depositary will deliver to the holder at the same time a new depositary receipt evidencing the excess number of depositary shares. In no event will the depositary deliver fractional shares of preferred stock upon surrender of depositary receipts. Holders of preferred stock thus withdrawn may not thereafter deposit those shares under the deposit agreement or receive depositary receipts evidencing depositary shares therefor.

Redemption of Depositary Shares

Whenever we redeem shares of preferred stock held by the depositary, the depositary will redeem as of the same redemption date the number of depositary shares representing shares of the preferred stock so redeemed, so long as we have paid in full to the depositary the redemption price of the preferred stock to be redeemed plus an amount equal to any accumulated and unpaid dividends on the preferred stock to the date fixed for redemption. The redemption price per depositary share will be equal to the redemption price and any other amounts per share payable on the preferred stock multiplied by the fraction of a share of preferred stock represented by one depositary share. If less than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or pro rata or by any other equitable method as may be determined by the depositary.

After the date fixed for redemption, depositary shares called for redemption will no longer be deemed to be outstanding and all rights of the holders of depositary shares will cease, except the right to receive the monies payable upon redemption and any money or other property to which the holders of the depositary shares were entitled upon redemption upon surrender to the depositary of the depositary receipts evidencing the depositary shares.

Voting the Preferred Stock

Upon receipt of notice of any meeting at which the holders of the preferred stock are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the depositary receipts relating to that preferred stock. The record date for the depositary receipts relating to the preferred stock will be the same date as the record date for the preferred stock. Each record holder of the depositary shares on the record date will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the number of shares of preferred stock represented by that holder's depositary shares. The depositary will endeavor, insofar as practicable, to vote the number of shares of preferred stock represented by the depositary shares in accordance with those instructions, and we will agree to take all action that may be deemed necessary by the depositary in order to enable the depositary to do so. The depositary will not vote any shares of preferred stock except to the extent it receives specific instructions from the holders of depositary shares representing that number of shares of preferred stock.

Charges of Depositary

We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will pay charges of the depositary in connection with the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary receipts will pay transfer, income and other taxes and governmental charges and such other charges (including those in connection with the receipt and distribution of dividends, the sale or exercise of rights, the withdrawal of the preferred stock and the transferring, splitting or grouping of depositary receipts) as are expressly provided in the deposit agreement to be for their accounts. If these charges have not been paid by the holders of depositary receipts, the depositary may refuse to transfer depositary shares, withhold dividends and distributions and sell the depositary shares evidenced by the depositary receipt.

Table of Contents

Amendment and Termination of the Deposit Agreement

The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may be amended by agreement between us and the depositary. However, any amendment that materially and adversely alters the rights of the holders of depositary shares, other than fee changes, will not be effective unless the amendment has been approved by the holders of a majority of the outstanding depositary shares. The deposit agreement may be terminated by the depositary or us only if:

•: all outstanding depositary shares have been redeemed; or
•: there has been a final distribution of the preferred stock in connection with our dissolution and such distribution has been made to all the holders of depositary shares.

Resignation and Removal of Depositary

The depositary may resign at any time by delivering to us notice of its election to do so, and we may remove the depositary at any time. Any resignation or removal of the depositary will take effect upon our appointment of a successor depositary and its acceptance of such appointment. The successor depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having the requisite combined capital and surplus as set forth in the applicable agreement.

Notices

The depositary will forward to holders of depositary receipts all notices, reports and other communications, including proxy solicitation materials received from us, that are delivered to the depositary and that we are required to furnish to the holders of the preferred stock. In addition, the depositary will make available for inspection by holders of depositary receipts at the principal office of the depositary, and at such other places as it may from time to time deem advisable, any reports and communications we deliver to the depositary as the holder of preferred stock.

Limitation of Liability

Neither we nor the depositary will be liable if either is prevented or delayed by law or any circumstance beyond its control in performing its obligations. Our obligations and those of the depositary will be limited to performance in good faith of our and their duties thereunder. We and the depositary will not be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred stock unless satisfactory indemnity is furnished. We and the depositary may rely upon written advice of counsel or accountants, on information provided by persons presenting preferred stock for deposit, holders of depositary receipts or other persons believed to be competent to give such information and on documents believed to be genuine and to have been signed or presented by the proper party or parties.

Table of Contents

DESCRIPTION OF PURCHASE CONTRACTS AND PURCHASE UNITS

We may issue purchase contracts, including contracts obligating holders to purchase from or sell to us, and obligating us to sell to or purchase from the holders, a specified number of shares of our common stock, preferred stock or depositary shares at a future date or dates, which we refer to in this prospectus as purchase contracts. The price per share of common stock, preferred stock or depositary shares and the number of shares of each may be fixed at the time the purchase contracts are issued or may be determined by reference to a specific formula set forth in the purchase contracts. The purchase contracts may be issued separately or as part of units, often known as purchase units, consisting of one or more purchase contracts and beneficial interests in debt securities or any other securities described in the applicable prospectus supplement or any combination of the foregoing, securing the holders' obligations to purchase the common stock, preferred stock or depositary shares under the purchase contracts.

The purchase contracts may require us to make periodic payments to the holders of the purchase units or vice versa, and these payments may be unsecured or prefunded on some basis. The purchase contracts may require holders to secure their obligations under those contracts in a specified manner, including pledging their interest in another purchase contract.

The applicable prospectus supplement will describe the terms of the purchase contracts and purchase units, including, if applicable, collateral or depositary arrangements.

Table of Contents

DESCRIPTION OF WARRANTS

We may issue warrants to purchase debt securities, preferred stock, depositary shares or common stock. We may offer warrants separately or together with one or more additional warrants, debt securities, preferred stock, depositary shares or common stock, or any combination of those securities in the form of units, as described in the applicable prospectus supplement. If we issue warrants as part of a unit, the accompanying prospectus supplement will specify whether those warrants may be separated from the other securities in the unit prior to the expiration date of the warrants. The applicable prospectus supplement will also describe the following terms of any warrants:

•: the specific designation and aggregate number of, and the offering price at which we will issue, the warrants;
•: the currency or currency units in which the offering price, if any, and the exercise price are payable;
•: the date on which the right to exercise the warrants will begin and the date on which that right will expire or, if you may not continuously exercise the warrants throughout that period, the specific date or dates on which you may exercise the warrants;
•: whether the warrants are to be sold separately or with other securities as parts of units;
•: whether the warrants will be issued in definitive or global form or in any combination of these forms, although, in any case, the form of a warrant included in a unit will correspond to the form of the unit and of any security included in that unit;
•: any applicable material U.S. federal income tax consequences;
•: the identity of the warrant agent for the warrants and of any other depositaries, execution or paying agents, transfer agents, registrars or other agents;
•: the proposed listing, if any, of the warrants or any securities purchasable upon exercise of the warrants on any securities exchange;
•: the designation and terms of any equity securities purchasable upon exercise of the warrants;

•: if applicable, the date from and after which any warrants issued as part of a unit and the related debt securities, preferred stock, depositary shares or common stock will be separately transferable;
•: the number of shares of preferred stock, the number of depositary shares or the number of shares of common stock purchasable upon exercise of a warrant and the price at which those shares may be purchased;
•: if applicable, the minimum or maximum amount of the warrants that may be exercised at any one time;
•: information with respect to book-entry procedures, if any;
•: the antidilution provisions of, and other provisions for changes to or adjustment in the exercise price of, the warrants, if any;
•: any redemption or call provisions; and
•: any additional terms of the warrants, including terms, procedures and limitations relating to the exchange or exercise of the warrants.

Table of Contents

FORMS OF SECURITIES

Each debt security, depositary share, purchase contract, purchase unit and warrant will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Unless the applicable prospectus supplement provides otherwise, certificated securities in definitive form and global securities will be issued in registered form. Definitive securities name you or your nominee as the owner of the security, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable. Global securities name a depositary or its nominee as the owner of the debt securities, depositary shares, purchase contracts, purchase units or warrants represented by these global securities. The depositary maintains a computerized system that will reflect each investor's beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below.

Registered Global Securities

We may issue the registered debt securities, depositary shares, purchase contracts, purchase units and warrants in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees.

If not described below, any specific terms of the depositary arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements.

Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. Upon the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants' accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some states may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes under the applicable indenture, purchase contract, warrant agreement or purchase unit agreement. Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the applicable indenture, depositary share agreement, purchase contract,

Table of Contents

purchase unit agreement or warrant agreement. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture, depositary share agreement, purchase contract, purchase unit agreement or warrant agreement. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the applicable indenture, depositary share agreement, purchase contract, purchase unit agreement or warrant agreement, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal, premium, if any, and interest payments on debt securities, and any payments to holders with respect to warrants, purchase agreements or purchase units, represented by a registered global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of us, the trustees, the warrant agents, the unit agents or any other agent of ours, agent of the trustees or agent of the warrant agents or unit agents will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

We expect that the depositary for any of the securities represented by a registered global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders on that registered global security, will immediately credit participants' accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers or registered in "street name," and will be the responsibility of those participants.

If the depositary for any of the securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Securities Exchange Act of 1934, and a successor depositary registered as a clearing agency under the Securities Exchange Act of 1934 is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee, warrant agent, unit agent or other relevant agent of ours or theirs. It is expected that the depositary's instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.

PLAN OF DISTRIBUTION

We may sell securities:

•: through underwriters;
•: through dealers;
•: through agents;
•: directly to purchasers; or
•: through a combination of any of these methods of sale.

In addition, we may issue the securities as a dividend or distribution or in a subscription rights offering to our existing security holders.

We may directly solicit offers to purchase securities, or agents may be designated to solicit such offers. We will, in the prospectus supplement relating to such offering, name any agent that could be viewed as an underwriter under the Securities Act, and describe any commissions that we must pay. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable prospectus supplement, on a firm commitment basis. This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement.

The distribution of the securities may be effected from time to time in one or more transactions:

•: at a fixed price, or prices, which may be changed from time to time;
•: at market prices prevailing at the time of sale;
•: at prices related to such prevailing market prices; or
•: at negotiated prices.

Each prospectus supplement will describe the method of distribution of the securities and any applicable restrictions.

The prospectus supplement with respect to the securities of a particular series will describe the terms of the offering of the securities, including the following:

•: the name of the agent or any underwriters;
•: the public offering or purchase price;
•: any discounts and commissions to be allowed or paid to the agent or underwriters;
•: all other items constituting underwriting compensation;
•: any discounts and commissions to be allowed or paid to dealers; and
•: any exchanges on which the securities will be listed.

If any underwriters or agents are utilized in the sale of the securities in respect of which this prospectus is delivered, we will enter into an underwriting agreement or other agreement with them at the time of sale to them, and we will set forth in the prospectus supplement relating to such offering the names of the underwriters or agents and the terms of the related agreement with them.

If a dealer is utilized in the sale of the securities in respect of which the prospectus is delivered, we will sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale.

Table of Contents

If we offer securities in a subscription rights offering to our existing security holders, we may enter into a standby underwriting agreement with dealers, acting as standby underwriters. We may pay the standby underwriters a commitment fee for the securities they commit to purchase on a standby basis. If we do not enter into a standby underwriting arrangement, we may retain a dealer-manager to manage a subscription rights offering for us.

Agents, underwriters, dealers and other persons may be entitled under agreements which they may enter into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, and may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

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

•: the purchase by an institution of the securities covered under that contract shall not at the time of delivery be prohibited under the laws of the jurisdiction to which that institution is subject; and
•: if the securities are also being sold to underwriters acting as principals for their own account, the underwriters shall have purchased such securities not sold for delayed delivery. The underwriters and other persons acting as our agents will not have any responsibility in respect of the validity or performance of delayed delivery contracts.

Certain agents, underwriters and dealers, and their associates and affiliates may be customers of, have borrowing relationships with, engage in other transactions with, and/or perform services, including investment banking services, for us or one or more of our respective affiliates in the ordinary course of business.

In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may overallot in connection with the offering, creating a short position for their own accounts. In addition, to cover overallotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.

Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. The applicable prospectus supplement may provide that the original issue date for your securities may be more than three scheduled business days after the trade date for your securities. Accordingly, in such a case, if you wish to trade securities on any date prior to the third business day before the original issue date for your securities, you will be required, by virtue of the fact that your securities initially are

expected to settle in more than three scheduled business days after the trade date for your securities, to make alternative settlement arrangements to prevent a failed settlement.

The securities may be new issues of securities and may have no established trading market. The securities may or may not be listed on a national securities exchange. We can make no assurance as to the liquidity of or the existence of trading markets for any of the securities.

In compliance with the guidelines of the Financial Industry Regulatory Authority, or FINRA, the aggregate maximum discount, commission or agency fees or other items constituting underwriting compensation to be received by any FINRA member or independent broker-dealer will not exceed 8% of the proceeds from any offering pursuant to this prospectus and any applicable prospectus supplement.
