The close of business on April 17, 2006 has been fixed as the record date for determining the stockholders of the Company entitled to notice of and to vote at the annual meeting. All holders of record of Common Stock of the Company at that date are entitled to vote at the annual meeting or any adjournment or postponement of the annual meeting.

Please complete, sign and mail the enclosed Proxy in the accompanying envelope even if you intend to be present at the annual meeting. Please sign the enclosed Proxy exactly as your name appears on it. Returning the Proxy will not limit your right to vote in person or to attend the annual meeting. If you hold shares of Common Stock of the Company in more than one name, or if your shares of Common Stock of the Company are registered in more than one way, you may receive more than one copy of the proxy material. If so, please sign and return each of the Proxies that you receive so that all of your shares of Common Stock of the Company may be voted.

The annual meeting will be held to vote on the first four items listed above, tabulate the votes cast in respect of those items and report the results of the vote. No presentations or other business matters are planned for the annual meeting.

This Proxy Statement and the accompanying proxy card are furnished in connection with the solicitation of proxies by the Board of Directors of Silgan Holdings Inc., or Silgan Holdings or the Company, for use at our annual meeting of stockholders, or the Meeting, to be held at the Courtyard by Marriott - Stamford Downtown, 275 Summer Street, Stamford, Connecticut 06901, on Wednesday, June 7, 2006, at 9:00 a.m., and at any postponements or adjournments of the Meeting. This Proxy Statement and the accompanying proxy card will first be mailed to stockholders on or about May , 2006.

Only holders of record of our Common Stock as of the close of business on April 17, 2006, the Record Date, will be entitled to notice of and to vote at the Meeting. As of the Record Date, we had 37,267,808 shares of our Common Stock outstanding. Each share of our Common Stock is entitled to one vote. We have no other class of voting securities issued and outstanding. The presence in person or by proxy of the holders of a majority of the outstanding shares of our Common Stock will be necessary to constitute a quorum for the transaction of business at the Meeting.

All shares of our Common Stock represented by properly executed proxies will be voted in accordance with the instructions indicated on such proxies unless such proxies previously have been revoked. If any proxies do not contain voting instructions, the shares of our Common Stock represented by such proxies will be voted FOR the election of the nominees for director listed below to serve until our annual meeting of stockholders in 2009 and until their successors are duly elected and qualified, FOR the authorization and approval of the Amended and Restated Certificate of Incorporation of the Company, FOR the approval of the amendment to the Silgan Holdings Inc. Senior Executive Performance Plan and FOR the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2006. We do not anticipate that any other matters will be brought before the Meeting. If any other matters properly come before the Meeting, the shares of our Common Stock represented by all properly executed proxies will be voted in accordance with the judgment of the persons named on such proxies. Shares of our Common Stock abstaining, and shares of our Common Stock held in street name as to which a broker has not voted on some matters but has voted on other matters, or Broker Shares, will be included in determining whether a quorum exists at the Meeting. Approval of each matter specified in the Notice of Meeting requires the affirmative vote of a majority of shares of our Common Stock present in person or by proxy at the Meeting, assuming that a quorum exists at the Meeting. Stockholders may not cumulate their votes. Abstentions and Broker Shares that have not been voted with respect to a particular proposal will not be counted in determining the total number of votes cast or in determining whether such proposal has received the requisite number of affirmative votes.

You may revoke your proxy at any time before it is exercised at the Meeting by (1) delivering to the Secretary of the Company a duly executed proxy bearing a later date; (2) filing a written notice of revocation with the Secretary of the Company; or (3) appearing at the Meeting and voting in person.

In addition to solicitations by mail, some of our directors, officers and employees may solicit proxies for the Meeting personally or by telephone without extra remuneration. We will also provide persons, banks, brokerage

firms, custodians, nominees, fiduciaries and corporations holding shares in their names or in the names of nominees, which in either case are beneficially owned by others, with proxy materials for transmittal to such beneficial owners and will reimburse such record owners for their expenses in doing so. The Company will bear the costs of soliciting proxies.

Our Board of Directors is currently composed of six members, divided evenly into three classes (designated Class I, Class II and Class III) with each class of directors serving staggered three-year terms. At each annual meeting of stockholders, the term of office of one class of directors of the Company expires, and directors nominated to the class of directors whose term is expiring at such annual meeting will be elected for a term of three years. Our remaining directors continue in office until their respective terms expire and until their successors are duly elected and qualified. Accordingly, at each annual meeting of stockholders of the Company one class of our directors will be elected, and each of our directors will be required to stand for election once every three years. At the Meeting, the term of office for our Class III Directors expires.

Our Class III Directors currently are Messrs. Jeffrey C. Crowe and Edward A. Lapekas. Pursuant to the Amended and Restated Stockholders Agreement dated as of November 6, 2001, or the Stockholders Agreement, among R. Philip Silver, D. Greg Horrigan and the Company, each of Messrs. Crowe and Lapekas was nominated for re-election at the Meeting as Class III Directors of the Company, to serve until our annual meeting of stockholders in 2009 and until his successor has been duly elected and qualified. You should read the section in this Proxy Statement titled “Certain Relationships and Related Transactions—Stockholders Agreement” for a description of the material provisions of the Stockholders Agreement.

Each nominee for Class III Director of the Company has consented to be named in this Proxy Statement and to serve on our Board of Directors if elected. If, prior to the Meeting, any nominee should become unavailable to serve on our Board of Directors for any reason, the shares of our Common Stock represented by all properly executed proxies will be voted for such alternate individual as shall be nominated pursuant to the Stockholders Agreement and designated by our Board of Directors.

We provide below certain information regarding each nominee for Class III Director of the Company and each Director of the Company whose term of office continues after the Meeting, including the individual’s age (as of December 31, 2005), principal occupation and business experience during at least the last five years, other directorships currently held and the year in which such individual was first elected a director of the Company.

THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE FOR BOTH NOMINEES FOR DIRECTOR (CLASS III) OF THE COMPANY.

R. Philip Silver, age 63, has been our Co-Chairman of the Board in a non-executive capacity since March 2006. Prior to that, Mr. Silver was our Co-Chief Executive Officer from March 1994 until March 2006. Mr. Silver was also our Co-Chairman of the Board in an executive capacity from August 2004 until March 2006 and, prior to that, our Chairman of the Board in an executive capacity. Mr. Silver is one of our co-founders and has been a Director since our inception in 1987. Prior to founding the Company in 1987, Mr. Silver was a consultant to the packaging industry. Mr. Silver was President of Continental Can Company from June 1983 to August 1986.

Until his retirement in 2000, Mr. Alden was Vice Chairman of UPS since 1996 and a director of UPS since 1988. Mr. Alden is also a director of Barnes Group Inc., The D & B Corporation and Arkansas Best Corporation.

Messrs. Crowe and Lapekas were elected as Directors of the Company at our annual meeting of stockholders in 2003. Messrs. Silver and Jennings were elected as Directors of the Company at our annual meeting of stockholders in 2004, and Messrs. Horrigan and Alden were elected as Directors of the Company at our annual meeting of stockholders in 2005.

Each of John W. Alden, Jeffrey C. Crowe, William C. Jennings and Edward A. Lapekas is an “independent director,” as defined in Rule 4200(a)(15) of the listing standards of the Nasdaq Stock Market. The independent directors held four meetings during 2005 following regularly scheduled quarterly meetings of the Board of Directors, without the presence of management or any inside directors.

Our Board of Directors met five times and acted by written consent fourteen times during 2005. Each of our Directors attended more than 75 percent of the aggregate of: (1) the total number of meetings of the Board of

Directors held in 2005 during which he was a Director and (2) the total number of meetings held in 2005 by all committees of the Board of Directors on which he served during which he was a Director.

The Company does not have a policy with regard to director attendance at annual meetings of stockholders. Two of our directors attended last year’s annual meeting of stockholders.

Each of our non-executive Co-Chairmen of the Board (Messrs. Silver and Horrigan) are paid an annual retainer fee of $100,000 for their service on our Board of Directors, plus travel and other reasonable out-of-pocket expenses. Our other Directors who do not receive compensation as officers or employees of the Company or any of our affiliates are paid an annual retainer fee of $36,000 for their service on our Board of Directors and a fee of $2,000 for each meeting of our Board of Directors that they attend and for each meeting of a committee of our Board of Directors that they attend, plus travel and other reasonable out-of-pocket expenses. Additionally, all Directors (including our Co-Chairmen of the Board) who do not receive compensation as officers or employees of the Company or any of our affiliates receive annual director awards, on the first business day after our annual meeting of stockholders, having an aggregate fair market value of $50,000 as of the date of grant, of either restricted shares of our Common Stock or restricted stock units related to shares of our Common Stock, in the discretion of the Board of Directors, under the Silgan Holdings Inc. 2004 Stock Incentive Plan, or the 2004 Stock Incentive Plan. Members of the Audit Committee of our Board of Directors are also paid an annual retainer fee of $12,000 for their service on the Audit Committee, and the chairpersons of each of the Audit and Compensation Committees of our Board of Directors are also paid an annual retainer fee of $10,000 for their service as chairperson of such committee.

Any Director who is an officer or employee of the Company or any of our affiliates would not receive any annual retainer or meeting fees or any awards under the 2004 Stock Incentive Plan.

Our Board of Directors has two standing committees. The principal responsibilities of each of the standing committees and the members of such committees are set forth below.

1. Audit Committee. The Audit Committee has the responsibility of overseeing the Company’s financial reporting process on behalf of our Board of Directors. The functions performed by the Audit Committee are described in the section of this Proxy Statement titled “Report of the Audit Committee.” During 2005, the Audit Committee held nine meetings and acted by written consent four times. The Audit Committee consists of Messrs. Jennings, Alden, Crowe and Lapekas, each of whom our Board of Directors has determined is independent as required by the written charter of the Audit Committee and the applicable listing standards of the Nasdaq Stock Market. All of our “independent directors” are members of the Audit Committee. Mr. Jennings is the Chairperson of the Audit Committee. The Board of Directors has determined that Mr. Jennings meets the criteria of an “audit committee financial expert” under applicable rules of the Securities and Exchange Commission, or the SEC. Mr. Jennings’ extensive background and experience includes leading the risk management and internal control consulting practice of PricewaterhouseCoopers LLP, serving as senior audit partner at Coopers & Lybrand and serving as Chief Financial Officer of Bankers Trust Company.

2. Compensation Committee. The Compensation Committee has the responsibility of reviewing and approving matters relating to the compensation of all executive officers of the Company (including all executive officers listed in the Summary Compensation Table in the section of this Proxy Statement titled “Executive Compensation”). The Compensation Committee also is responsible for administering the 2004 Stock Incentive Plan, making awards and grants under the 2004 Stock Incentive Plan to officers and other key employees of the Company and its subsidiaries and setting performance goals and certifying performance levels in respect of performance awards made under the 2004 Stock Incentive Plan. The Compensation Committee held two

meetings and acted by written consent eight times during 2005. The Compensation Committee consists of Messrs. Crowe, Alden, Jennings and Lapekas, each of whom is an “independent director” under the applicable listing standards of the Nasdaq Stock Market. Mr. Crowe is the Chairperson of the Compensation Committee.

In November 2001, the Company and Messrs. Silver and Horrigan, our Co-Chairmen of the Board, entered into the Stockholders Agreement. You should read the section in this Proxy Statement titled “Certain Relationships and Related Transactions—Stockholders Agreement” for a description of the material terms of the Stockholders Agreement. Under the Stockholders Agreement, Messrs. Silver and Horrigan have the contractual right to nominate for election all directors of the Company so long as Messrs. Silver and Horrigan beneficially own an aggregate of at least 7,153,090 shares of our Common Stock (as adjusted for the stock split effected on September 15, 2005). As of the date of this Proxy Statement, Messrs. Silver and Horrigan beneficially own an aggregate of 13,337,916 shares (or approximately 35.8%) of our Common Stock. In the very unlikely event that either of Messrs. Silver or Horrigan notifies our Board of Directors that they cannot agree on an individual for any nominee for director or if at least 45 days prior to our annual meeting of stockholders they fail to nominate for election at such annual meeting the requisite number of individuals to stand for election, then our Board of Directors has the right to nominate for director the number of individuals that Messrs. Silver and Horrigan could not agree on as nominees or failed to nominate timely.

Accordingly, our Board of Directors does not have a nominating committee because the right to nominate all directors has been contractually granted to Messrs. Silver and Horrigan, and our Board of Directors deems it very unlikely at this time that they would have to nominate for election any director. As a result, the Company does not have a nominating committee charter, does not have a policy to consider director candidates recommended by stockholders and does not have a process for identifying or evaluating nominees for director. Both nominees for Class III Director of the Company to be elected at the Meeting were nominated by Messrs. Silver and Horrigan pursuant to the Stockholders Agreement.

The Company’s Board of Directors has a formal process for security holders to send communications to it. Security holders may send written communications addressed to the Board of Directors or to any specified Director of the Company by mail to the Company’s office in Stamford, Connecticut. If the Company receives at its office in Stamford, Connecticut any such written communications, the Company will forward such written communications directly to all members of the Board of Directors or to such specified Director of the Company, as the case may be.

The Audit Committee is governed by a written charter approved by the Company’s Board of Directors. In accordance with the written charter of the Audit Committee and applicable listing standards of the Nasdaq Stock Market, all members of the Audit Committee are independent. The Audit Committee held nine meetings during 2005.

The Audit Committee provides assistance to the Board of Directors of the Company in fulfilling its oversight responsibility relating to the Company’s consolidated financial statements and financial reporting process, systems of internal accounting and financial controls, internal audit activities and compliance with legal and regulatory requirements relating to accounting and financial reporting matters and the annual independent audits of the Company’s consolidated financial statements and the effectiveness of the Company’s internal control over financial reporting. Management of the Company is responsible for the consolidated financial statements and reporting process of the Company, including maintaining effective internal control over financial reporting and assessing the effectiveness of the Company’s internal control over financial reporting. Ernst & Young LLP, the independent registered public accounting firm of the Company, is responsible for performing an independent audit of the Company’s consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) and for issuing a report thereon. The independent registered public accounting firm is also responsible for auditing management’s assessment that the Company maintained effective internal control over financial reporting and the effectiveness of the Company’s internal control over financial reporting. The Audit Committee’s responsibility is to oversee these audits and the financial reporting process of the Company.

In fulfilling its oversight responsibilities, the Audit Committee discussed with management, the Company’s internal auditors and the Company’s independent registered public accounting firm the overall scope and plans for the Company’s audits. The Audit Committee met with the Company’s internal auditors and independent registered public accounting firm, with and without management present, to discuss the Company’s audits, the Company’s consolidated financial statements and the Company’s internal control over financial reporting. The Audit Committee also reviewed and discussed with management and the Company’s independent registered public accounting firm the audited consolidated financial statements of the Company included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2005. Additionally, the Audit Committee reviewed with management its report on its assessment of the effectiveness of the Company’s internal control over financial reporting and the independent registered public accounting firm’s report on management’s assessment and the effectiveness of the Company’s internal control over financial reporting.

The Audit Committee also discussed with the Company’s independent registered public accounting firm its independence from management and the Company, including the matters in the written disclosures and the letter required by the Independence Standards Board, and considered the compatibility of nonaudit services with such firm’s independence. Additionally, in assessing such firm’s independence, the Audit Committee reviewed the amount of fees paid to Ernst & Young LLP for audit and nonaudit services.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors of the Company that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2005 for filing with the SEC.

The Audit Committee is also directly responsible for the appointment, compensation, retention and oversight of the work of the independent registered public accounting firm of the Company. Accordingly, the Audit Committee has approved, subject to stockholder ratification, the selection of Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2006.

The Audit Committee has adopted a formal policy, consistent with its written charter, that requires its approval in advance for any audit, audit-related, tax and other services to be performed by the Company’s independent registered public accounting firm. Pursuant to its formal policy, the Audit Committee approved in advance all audit, audit-related, tax and other services performed by the Company’s independent registered public accounting firm in 2005. This policy provides that the Audit Committee may delegate to any of its members the authority to approve in advance any audit and nonaudit services to be performed by the Company’s independent registered public accounting firm, and, in such case, requires such member to report any decisions to the Audit Committee at its next scheduled meeting.

Our Board of Directors appoints the officers of the Company. The officers of our subsidiaries are appointed by the respective boards of directors of our subsidiaries. We provide below certain information concerning the executive officers of the Company, including each individual’s age (as of December 31, 2005). There are no family relationships among any of the directors or executive officers of the Company.

Our Board of Directors has adopted a Code of Ethics applicable to our principal executive officer, principal financial officer, principal accounting officer or controller in order to deter wrongdoing and to promote the conduct of the Company’s business in an honest, lawful and ethical manner. A copy of this Code of Ethics was filed as an exhibit to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2003.

In November 2001, Messrs. Silver and Horrigan and the Company entered into the Stockholders Agreement. The Stockholders Agreement replaced in its entirety the Stockholders Agreement dated as of February 14, 1997, or the 1997 Stockholders Agreement, among Messrs. Silver and Horrigan and The Morgan Stanley Leveraged Equity Fund II, L.P., or MSLEF II, a former stockholder of the Company and an affiliate of Morgan Stanley & Co. Incorporated.

Under the Stockholders Agreement, the Group (as defined in the Stockholders Agreement) has the right to nominate for election all directors of the Company until the Group holds less than one-half of the number of shares of our Common Stock held by it in the aggregate on February 14, 1997. The Group generally includes Messrs. Silver and Horrigan and their affiliates and related family transferees and estates. At least one of the Group’s nominees must be either Mr. Silver or Mr. Horrigan. On February 14, 1997, the Group held 14,306,180 shares of our Common Stock in the aggregate (as adjusted for the stock split effected on September 15, 2005). Additionally, the Group has the right to nominate for election either Mr. Silver or Mr. Horrigan as a member of our Board of Directors when the Group no longer holds at least one-half of the number of shares of our Common Stock held by it in the aggregate on February 14, 1997 but beneficially owns 5% of our Common Stock. The Stockholders Agreement continues until the death or disability of both of Messrs. Silver and Horrigan.

If either Mr. Silver or Mr. Horrigan notifies our Board of Directors that the Group cannot agree on an individual for any of its nominees under the Stockholders Agreement or if at least 45 days prior to our annual meeting of stockholders the Group fails to nominate for election at such annual meeting the requisite number of individuals to stand for election to our Board of Directors at such annual meeting, then our Board of Directors has the right to nominate for election to our Board of Directors the number of individuals that Messrs. Silver and Horrigan could not agree on as nominees or that the Group failed to nominate timely.

The provisions of the Stockholders Agreement could have the effect of delaying, deferring or preventing a change of control of the Company and preventing our stockholders from receiving a premium for their shares of our Common Stock in any proposed acquisition of the Company.

In 2005, Landstar provided transportation services to our subsidiaries. We expect that Landstar will continue to provide transportation services to our subsidiaries in 2006. We believe that these transportation services were provided on terms no less favorable to us than provided generally to Landstar’s other customers. We paid Landstar approximately $1.3 million in 2005 for such transportation services, which amount represented approximately 0.05% of Landstar’s revenues in 2005. Mr. Jeffrey C. Crowe, a Director of the Company, is the Chairman of the Board of Landstar.

In the table below, we provide information concerning the annual and long-term compensation for services rendered in all capacities to the Company during the fiscal years ended December 31, 2005, 2004 and 2003 of certain persons, collectively referred to as the Named Executive Officers, who at December 31, 2005 were the Chief Executive Officer of the Company and the other four most highly compensated executive officers of the Company.

In the table below we provide information about equity securities of the Company authorized for issuance under all of the Company’s equity compensation plans. The information is as of December 31, 2005.

The Company has established pension plans covering a substantial number of its salaried employees. These pension plans are defined benefit plans intended to be qualified pension plans under Section 401(a) of the Code under which pension costs are determined annually on an actuarial basis with contributions made accordingly.

The table below illustrates the estimated annual normal retirement benefits that are payable under the pension plan, or the Containers Pension Plan, covering salaried employees of Silgan Containers and Silgan Holdings (other than Messrs. Silver and Horrigan (who were employees of Silgan Holdings until March 1, 2006) and Messrs. Allott and Lewis, none of whom participate in any pension plan of the Company). The benefit levels assume retirement at age 65, the years of service shown, continued existence of the Containers Pension Plan without substantial change and payment in the form of a single life annuity.

Benefits under the Containers Pension Plan are based on the participant’s average base pay (the “Salary” column in the Summary Compensation Table) over the final three years of employment. The amount of average base pay taken into account for any year is limited by Section 401(a)(17) of the Code, which imposes a cap of $210,000 (to be indexed for inflation) on compensation taken into account for 2005. Benefits under the Containers Pension Plan are not subject to any deduction for social security or other offset amounts.

As of December 31, 2005, Mr. Beam, the only Named Executive Officer who is an eligible participant under the Containers Pension Plan, had approximately eighteen years of credited service under the Containers Pension Plan. Mr. Beam also participates in the Containers Supplemental Plan, a nonqualified defined contribution plan that provides for contributions that are intended, among other things, to make up for benefits not payable under the Containers Pension Plan due to Code limitations. Amounts contributed by Silgan Containers for Mr. Beam under the Containers Supplemental Plan are included in the “All Other Compensation” column of the Summary Compensation Table.

The table below illustrates the estimated annual normal retirement benefits that are payable under the pension plan, or the Plastics Pension Plan, covering substantially all of the salaried employees of Silgan Plastics.

The benefit levels assume retirement age at 65, the years of service shown, continued existence of the Plastics Pension Plan without substantial change and payment in the form of a single life annuity.

Benefits under the Plastics Pension Plan are based on the participant’s average total cash compensation (the “Salary” and “Bonus” columns in the Summary Compensation Table) over the final 36 months of employment or over the highest three of the final five calendar years of employment, whichever produces the greater average compensation. In computing this average, compensation for any year cannot exceed 125% of base pay. Compensation used in determining benefits is also limited by Section 401(a)(17) of the Code, which imposes the cap indicated above.

Benefits under the Plastics Pension Plan are determined based on two methods. Under the first method, the Plastics Pension Plan provides for benefits based on a formula without any offset for social security. Most of Silgan Plastics’ officers are eligible participants under the Plastics Pension Plan based on this first method and the above table is based on this first method. Under the second method, benefits under the Plastics Pension Plan are based on one of three formulas, one of which provides for an offset for social security. Additionally, officers of Silgan Plastics are eligible to participate in the Plastics Supplemental Plan, a nonqualified defined contribution plan that provides for contributions that are intended, among other things, to make up for benefits not payable under the Plastics Pension Plan due to Code limitations.

Anthony J. Allott, President and Chief Executive Officer of the Company, entered into an employment agreement with the Company in April 2004. Mr. Allott’s employment agreement provides for, among other things, a severance benefit if Mr. Allott is terminated by the Company without cause in an amount equal to (i) the sum of his then current annual salary plus (ii) his annual bonus, calculated at the then current maximum amount payable as previously approved by the Compensation Committee (for 2006, 100% of his then current salary).

Robert B. Lewis, Executive Vice President and Chief Financial Officer of the Company, is entitled to a severance benefit, as provided in an employment letter from the Company dated June 30, 2004, if Mr. Lewis is terminated by the Company without cause in an amount equal to (i) the sum of his then current salary plus (ii) his annual bonus, calculated at 30% of his then current salary.

James D. Beam, President of Silgan Containers, has entered into an employment agreement with Silgan Containers. The initial term of his employment agreement was three years from its effective date, and the term has been, and will continue to be, automatically extended for successive one year periods unless terminated pursuant to the terms of his employment agreement. Mr. Beam’s employment agreement provides for, among other things, a minimum severance benefit equal to his then current base salary and benefits for a period of up to one year following termination if (i) Mr. Beam is terminated by Silgan Containers for any reason other than death, disability or for cause as specified in his employment agreement or (ii) Mr. Beam voluntarily terminates his employment due to a demotion, all as specified in his employment agreement.

The goals of the Company’s executive compensation program are as follows: (i) to attract and retain executives and to provide fair compensation to them taking into account the responsibilities undertaken by them; (ii) to motivate the Company’s executives to achieve the Company’s business strategy; and (iii) to align the interests of the Company’s executives and stockholders through the granting or awarding of equity based compensation. The principal components of the Company’s executive officer compensation program are base salary, annual cash bonuses and equity based compensation. Certain of the Company’s executive officers also receive additional forms of compensation as described in the Summary Compensation Table of this Proxy Statement and footnote (c) to the Summary Compensation Table and in the section in this Proxy Statement titled “Executive Compensation—Pension Plans.” For 2005, the Compensation Committee approved the compensation of all executive officers of the Company, including all Named Executive Officers.

Base salaries for the Company’s executive officers are determined, in part, through general geographic market conditions and comparisons with companies in the packaging industry and other companies with which the Company competes for personnel. Additionally, other factors are considered such as individual experience and performance and the overall performance of the Company. Each executive’s base salary is reviewed on an annual basis and may be adjusted, consistent with the terms of any applicable employment agreement, based on (i) the individual’s contribution to the Company over the preceding year; (ii) a change in the individual’s responsibilities over the preceding year; (iii) any change in median competitive pay levels; or (iv) a general increase in the cost of living.

Annual cash bonuses are paid to Messrs. Silver and Horrigan for the period of their employment with the Company (for 2006, until March 1, 2006) pursuant to the Company’s Senior Executive Performance Plan. At the beginning of each year, the Compensation Committee establishes one or more performance goals and related performance goal targets for such year pursuant to the Senior Executive Performance Plan. Following such year, the Compensation Committee certifies the extent to which the performance goal targets for such year were met and then cash bonuses are paid accordingly to Messrs. Silver and Horrigan pursuant to the Senior Executive Performance Plan. Annual cash bonuses are paid to Messrs. Allott and Lewis pursuant to their employment agreements based on the same performance goal targets established by the Compensation Committee pursuant to the Senior Executive Performance Plan and the extent to which such performance goal targets were met. As described in the section of this Proxy Statement titled “Approval of the Amendment to the Silgan Holdings Inc. Senior Executive Performance Plan,” the Compensation Committee approved an amendment to the Senior Executive Performance Plan on March 1, 2006, subject to approval by the stockholders at the Meeting. The amendment to the Senior Executive Performance Plan solely relates to the addition of Anthony J. Allott, our new Chief Executive Officer, as a person eligible to participate in the plan, and to the establishment of a maximum cash bonus amount payable to Mr. Allott under the plan for each year. Annual cash bonuses are paid to the other officers of the Company calculated on the basis of a weighted average of the levels of bonuses paid to officers of the Company’s business units. Annual cash bonuses are paid in the beginning of the year following the year in which they are earned.

Annual cash bonuses are paid to officers of the Company’s business units based upon such business unit achieving certain financial targets and, in some years, meeting certain organizational goals. The financial target levels and, if applicable, organizational goals of the Company’s business units for a given year are established at the beginning of such year. The amount of the bonus of each such officer is determined by a formula which calculates such bonus based on the percentage that the actual applicable financial target represents of the applicable financial target level and, if applicable, based on whether such organizational goals were met. In the

case of officers of Silgan Containers, a portion of their annual cash bonuses for 2005 was payable to them if Silgan Containers met certain organizational goals as established by the Compensation Committee at the beginning of the year, including management development, market related, operational and safety, working capital management, cost management and financial reporting goals. In the case of officers of Silgan Plastics, a portion of their annual cash bonuses for 2005 was payable to them if Silgan Plastics met certain organizational goals as established by the Compensation Committee at the beginning of the year, including working capital management goals and in some cases completion of a strategic planning effort. Annual cash bonuses are paid in the beginning of the year following the year in which they are earned.

The Compensation Committee of the Board of Directors is responsible for administering the 2004 Stock Incentive Plan. The Compensation Committee selects or approves award recipients, sets the terms and conditions of awards, makes adjustments to outstanding awards and to the share reserve as permitted by the 2004 Stock Incentive Plan, interprets the 2004 Stock Incentive Plan and prescribes rules for administering the 2004 Stock Incentive Plan. While the Compensation Committee is permitted to amend outstanding awards, it is not permitted to reduce the exercise price of any outstanding stock option or stock appreciation right without obtaining approval of the stockholders of the Company. The 2004 Stock Incentive Plan currently forms the basis of the Company’s long-term incentive compensation plan. The Compensation Committee believes that placing a portion of compensation in the form of equity achieves certain objectives: it aligns the interest of the Company’s executive officers and key employees with those of the Company’s stockholders; it gives executive officers and key employees a significant long-term interest in the Company’s success; and it helps the Company attract and retain executive officers and key employees. In determining to whom awards are granted, the terms of awards and the amount of an award for an executive officer or key employee, the Compensation Committee primarily considers the value of unvested awards previously granted and the prospective value of the awards to be granted. In 2005, no stock options were granted under the 2004 Stock Incentive Plan and restricted stock units, representing the right to receive an aggregate of 21,000 shares of our Common Stock, were awarded under the 2004 Stock Incentive Plan to three key employees of the Company’s subsidiaries. No awards were made to any of the Named Executive Officers listed in the Summary Compensation Table in 2005 under the 2004 Stock Incentive Plan. Additionally, in March 2005, the Compensation Committee fixed and established performance criteria for the Company’s 2005 fiscal year for potential grants of restricted stock units in 2006 under the 2004 Stock Incentive Plan to certain officers and other key employees of the Company and its subsidiaries. The performance criteria selected by the Compensation Committee was the Company’s earning before interest expense, provision for income taxes, depreciation and amortization expenses, or EBITDA, and the minimum level of performance required to be attained was based on the Company’s EBITDA for 2004.

For 2005, the base salary for each of Messrs. Silver and Horrigan was $766,875. The Compensation Committee used the factors described above under “Base Salary” to set Messrs. Silver’s and Horrigan’s base salary for 2005.

Additionally, for 2005, each of Messrs. Silver and Horrigan was awarded bonuses of $1,669,692 pursuant to the Company’s Senior Executive Performance Plan. They were awarded such bonuses because the maximum performance goal target relating to such bonuses established by the Compensation Committee pursuant to the Senior Executive Performance Plan at the beginning of 2005 was achieved in 2005. The amount of the bonuses awarded was the maximum amount that could be awarded to Messrs. Silver and Horrigan for 2005 under the Senior Executive Performance Plan. The performance goal for 2005 was based on the Company’s EBITDA, and the maximum performance goal target for 2005 was based on the Company’s EBITDA for 2004.

Section 162(m) of the Code disallows a federal income tax deduction to any publicly held corporation for compensation paid in excess of $1 million in any taxable year to an individual who is the chief executive officer or any of the four most highly compensated executive officers (other than the chief executive officer) employed by such corporation (or a member of its affiliated group) on the last day of such taxable year, but does allow a deduction for “performance-based compensation” in excess of $1 million the material terms of which are disclosed to and approved by stockholders. The Company’s intention is to maximize the tax deductibility of its compensation programs. However, because the Company believes that the use of prudent judgment in determining compensation levels is in the best interests of the Company and its stockholders, under some circumstances it may determine to pay amounts of compensation that may not be fully deductible. The Company reserves the right to use prudent judgment in establishing compensation policies to attract and retain qualified executives to manage the Company and to reward such executives for outstanding performance, while taking into consideration the financial impact of such actions on the Company.

In 2005, the Compensation Committee of our Board of Directors consisted of Messrs. Crowe, Alden, Jennings and Lapekas. During 2005, none of our executive officers served as: (i) a member of the compensation committee (or other board committee performing equivalent functions or, in the absence of any such committee, the entire board of directors) of another entity, one of whose executive officers served on the Compensation Committee of our Board of Directors, (ii) a director of another entity, one of whose executive officers served on our Board of Directors, or (iii) a member of the compensation committee (or other board committee performing equivalent functions or, in the absence of any such committee, the entire board of directors) of another entity, one of whose executive officers served on our Board of Directors. As described in the section of this Proxy Statement titled “Certain Relationships and Related Transactions—Other,” Landstar, a company of which Mr. Crowe is Chairman of the Board, provided transportation services to our subsidiaries in 2005 and is expected to continue to provide transportation services to our subsidiaries in 2006, all on terms, we believe, no less favorable to us than provided generally to Landstar’s other customers.

The graph below compares the Company’s Common Stock performance for the five year period ended December 31, 2005 with the performance of the Dow Jones Containers & Packaging Index and the Standard & Poor’s 500 Composite Stock Price Index, or the S&P 500 Index, for the same period by valuing the changes in common stock prices from December 31, 2000 through December 31, 2005 plus reinvested dividends. The companies included in the Dow Jones Containers & Packaging Index are: AptarGroup, Inc.; Ball Corporation; Bemis Company, Inc.; Chesapeake Corporation; Crown Holdings, Inc.; Owens-Illinois, Inc.; Packaging Corporation of America; Pactiv Corporation; Sealed Air Corporation; Smurfit Stone Container Corporation; Sonoco Products Company; and Temple-Inland, Inc. The graph below assumes in each case an initial investment of $100.00 on December 31, 2000 plus reinvestment of dividends, with the investment in the Dow Jones Containers & Packaging Index weighted on the basis of market capitalization.

In the table below, we provide information, as of the Record Date, with respect to the beneficial ownership of our Common Stock by (i) each current director and each Named Executive Officer of the Company, (ii) each person or entity who is known by the Company to own beneficially more than 5% of our Common Stock and (iii) by all executive officers and directors of the Company as a group. Except as otherwise described below, each of the persons named in the table below has sole voting and investment power with respect to the securities beneficially owned.

You are being asked to authorize and approve the Amended and Restated Certificate of Incorporation of the Company. The Amended and Restated Certificate of Incorporation amends and restates the Company’s current Restated Certificate of Incorporation dated February 11, 1997. The Board of Directors approved the Amended and Restated Certificate of Incorporation by a unanimous written consent dated as of April 10, 2006, subject to authorization and approval by the stockholders at the Meeting, and directed that the Amended and Restated Certificate of Incorporation be submitted for approval of the stockholders at the Meeting. A marked version of the Amended and Restated Certificate of Incorporation indicating the modifications from the Company’s Restated Certificate of Incorporation is set forth in Exhibit A to this Proxy Statement.

The Amended and Restated Certificate of Incorporation, among other things, increases the size of our Board of Directors from six members to seven members. If the Amended and Restated Certificate of Incorporation is approved by the stockholders at the Meeting, our Board of Directors intends to fill the vacancy resulting from such increase by electing Anthony J. Allott, our President and Chief Executive Officer, as a Class III Director. The Board of Directors believes that at least one of its members should be an executive officer of the Company. Mr. Allott’s term of office as a director would expire at the same time as the term of office would expire for our other Class III Directors in 2009. Other proposed changes in the Amended and Restated Certificate of Incorporation are being made to update information therein and to eliminate provisions regarding officers of the Company which are in the purview of the By-Laws of the Company. Specific changes include:

Stockholder approval of the Amended and Restated Certificate of Incorporation requires the favorable vote of a majority of the shares of our Common Stock present in person or by proxy at the Meeting.

THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE AUTHORIZATION AND APPROVAL OF THE AMENDED AND RESTATED CERTIFICATE OF INCORPORATION OF THE COMPANY.

You are being asked to approve the amendment to the Silgan Holdings Inc. Senior Executive Performance Plan and the material terms of the performance goals under the plan, as amended. This plan was adopted by the Board of Directors and the Compensation Committee of the Board of Directors on February 27, 2003, and adopted by our stockholders at our annual meeting of stockholders on June 5, 2003. The purpose of the plan is to attract and retain certain senior executives and motivate these senior executives to promote the profitability and growth of the Company, as well as to maximize the deductibility for tax purposes of compensation payable to these senior executives. The plan provides for payments of annual cash bonuses to these senior executives based on the attainment of pre-established performance goals for each fiscal year.

The Compensation Committee approved an amendment to the Senior Executive Performance Plan on March 1, 2006, subject to approval by the stockholders at the Meeting. The amendment to the Senior Executive Performance Plan solely relates to the addition of Anthony J. Allott, our new Chief Executive Officer, as a person eligible to participate in the plan, and to the establishment of a maximum cash bonus amount payable to Mr. Allott under the plan for each year.

A copy of the Amendment to the Senior Executive Performance Plan is set forth in Exhibit B to this Proxy Statement.

Stockholder approval of the amendment to the Senior Executive Performance Plan and the material terms of the performance goals under the plan, as amended, is required under Internal Revenue Service regulations in order to preserve the Company’s federal income tax deduction of payments made under the plan to these senior executives. Stockholder approval requires the favorable vote of a majority of shares of our Common Stock present in person or by proxy at the Meeting.

Section 162(m) of the Code sets limits on the Company’s federal income tax deduction for compensation paid in a taxable year to an individual who, on the last day of the taxable year, was (i) the Chief Executive Officer of the Company or (ii) among the four other most highly compensated executive officers of the Company whose compensation is reported in the Summary Compensation Table. “Qualified performance-based compensation,” which can include cash bonuses payable upon attainment of pre-established performance goals, is not subject to this tax deduction limit if certain conditions are met. One of the conditions is stockholder approval of the material terms of the performance goals under which the compensation will be paid. If

stockholders approve the amendment to the Senior Executive Performance Plan and the material terms of the performance goals under the plan, as amended, at the Meeting, then the compensation payable to Mr. Allott under the plan should be deductible for tax purposes. On March 1, 2006, the Company’s Compensation Committee approved, subject to approval by the stockholders at the Meeting of the amendment to the plan, the payment of an annual bonus for Mr. Allott for 2006 of up to 100% of his annual salary for 2006, with the amount of such annual bonus being calculated pursuant to a formula based on the Company’s earnings before interest expense, provision for income taxes, depreciation and amortization expenses for 2006 as compared to the Company’s earnings before interest expense, provision for income taxes, depreciation and amortization expenses for 2005.

If stockholders do not approve the amendment to the Senior Executive Performance Plan at the Meeting, then the amendment to the plan will not be implemented. In such event, the Compensation Committee has nevertheless approved the payment of a cash bonus to Mr. Allott for 2006 in an amount up to 100% of his annual salary for 2006, with the amount of such annual bonus being calculated on the same basis as it would have been calculated under the plan for 2006 had the amendment to the plan been approved by the stockholders at the Meeting, provided that in accordance with Section 162(m) of the Code the Company may not be able to deduct for tax purposes all amounts received by Mr. Allott as a bonus in 2006.

The material terms of the performance goals used to determine compensation payable under the plan consist of (i) the class of employees eligible to receive these cash bonuses; (ii) the types of business criteria on which the payments of cash bonuses are based; and (iii) the maximum amounts of cash bonuses that can be paid during a specified period to any senior executive under the plan.

Eligible Class: The amendment to the plan provides that cash bonuses under the plan may only be paid to Anthony J. Allott, the current President and Chief Executive Officer of the Company, and R. Philip Silver and D. Greg Horrigan, the Co-Chief Executive Officers of the Company until March 1, 2006. Messrs. Silver and Horrigan are entitled to receive payments under the plan on a pro rata basis for their service as Co-Chief Executive Officers until March 1, 2006, on which date they ceased to be employees of the Company and thus are no longer eligible to participate in the plan for periods from and after March 1, 2006.

Business Criteria: To determine whether cash bonuses will be paid under the plan and the amount of such cash bonuses, the Compensation Committee sets performance goals for each fiscal year of the Company. The performance goals will be based on the attainment by the Company of specified levels of various measures, which shall include one or more of the following: (i) net income; (ii) earnings per share; (iii) income from operations; (iv) earnings before interest expense and provision for income taxes (EBIT); (v) earnings before interest expense, provision for income taxes, depreciation and amortization expenses (EBITDA); (vi) economic value added; (vii) return on net assets; (viii) return on total assets; (ix) free cash flow from operations; (x) return on invested capital; (xi) return on stockholders’ equity; (xii) expense reduction; (xiii) working capital; (xiv) total shareholder return; and (xv) stock price performance of the Company’s Common Stock. On March 1, 2006, the Compensation Committee set a performance goal under the plan for the performance period of fiscal year 2006. The amount payable to each of the participating executives under the plan for 2006 shall be determined pursuant to a formula based on the Company’s EBITDA for 2006 as compared to the Company’s EBITDA for 2005.

The Compensation Committee may elect to exclude in measuring performance under any of these business criteria (i) unusual gains and unusual losses, (ii) the amount of all charges and expenses incurred or income earned in connection with any refinancing, restructuring, rationalization, recapitalization or reorganization involving the Company and its subsidiaries, (iii) the cumulative effects of accounting changes, (iv) discontinued operations, and (v) businesses, units, divisions, subsidiaries or other entities sold or acquired.

Maximum Amounts: For the fiscal year beginning January 1, 2006, the maximum cash bonus payable to all of the senior executives under the plan is $1,319,691. The maximum cash bonus payable to each of Messrs. Silver and Horrigan for fiscal year 2006 is $278,282. This amount represents a pro-rated amount of $1,669,692

(the maximum cash bonus that would have been payable to each of Messrs. Silver and Horrigan for the entire fiscal year 2006), reflecting the fact that they retired as Co-Chief Executive Officers on March 1, 2006 and were therefore not eligible to continue participating in the plan beyond their last date of employment. The amendment to the plan does not increase the maximum cash bonus amount payable to Messrs. Silver or Horrigan from last year. Assuming that the amendment to the plan is approved by our stockholders at the Meeting, the maximum cash bonus payable to Mr. Allott for fiscal year 2006 is $763,127 (100% of his projected annual salary for 2006).

The plan is administered by the Compensation Committee, which is comprised solely of “outside directors” meeting the requirements of the regulations under Code Section 162(m). Not later than 90 days after the beginning of each fiscal year, the Compensation Committee will establish in writing the business criteria that will be used to measure performance for such fiscal year, the specific target levels of performance required to achieve payment of cash bonuses, the method by which achievement of those targets will be measured and the maximum award for Mr. Allott for such fiscal year. Following the end of each fiscal year, the Compensation Committee will certify in writing the extent to which those targets have been attained, and, if the targets have been attained, cash bonuses will be paid as soon as practicable after the Compensation Committee makes its written certification.

The Compensation Committee has full authority to interpret the plan, establish rules and regulations relating to the operation of the plan, determine the amount of any cash bonuses under the plan, and make all determinations and take all other actions necessary or appropriate for the proper administration of the plan.

The plan may be terminated, amended or modified at any time by the unanimous vote of the members of the Compensation Committee. No amendment requiring stockholder approval under Code Section 162(m) or the Securities Exchange Act of 1934, as amended, or the Exchange Act, will be implemented without such approval, and no amendment adversely affecting a person’s rights to cash bonuses previously granted under the plan can be implemented without the agreement of such person.

THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE APPROVAL OF THE AMENDMENT TO THE SILGAN HOLDINGS INC. SENIOR EXECUTIVE PERFORMANCE PLAN AND THE MATERIAL TERMS OF THE PERFORMANCE GOALS UNDER THE PLAN, AS AMENDED.

The Audit Committee of the Board of Directors of the Company has appointed Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2006. The Board of Directors of the Company is requesting ratification of this appointment by the stockholders of the Company. It should be noted however that, even if this appointment is ratified by the stockholders of the Company, the Audit Committee in their discretion may replace Ernst & Young LLP as the Company’s independent registered public accounting firm and appoint a new independent registered public accounting firm for the Company at any time during the year if they determine that such a change would be in the best interests of the Company. In fact, under the direction of the Audit Committee, management of the Company has initiated a bid process for the audit of the Company’s 2006 consolidated financial statements, precipitated by the significant increase in the Company’s audit fees over the last couple of years. At this time, management is in the process of obtaining bids from Ernst & Young LLP and other “big four” accounting firms and expects to submit those bids to the Audit Committee shortly for their review and determination as to whether to change the Company’s independent registered public accounting firm for 2006.

A representative of Ernst & Young LLP is expected to be present at the Meeting and to be available to respond to appropriate questions from those attending the Meeting, but is not otherwise expected to make a statement.

THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2006.

Fees for audit services rendered by Ernst & Young LLP in 2005 and 2004 totaled $3.2 million and $3.6 million, respectively, in connection with the audit of the Company’s consolidated financial statements for such years, reviews of the Company’s unaudited financial statements included in its Quarterly Reports on Form 10-Q for such years, the audit of management’s assessment that the Company maintained effective internal control over financial reporting for such years and the audit of the effectiveness of the Company’s internal control over financial reporting for such years. Approximately $1.6 million and $2.0 million of the audit fees for 2005 and 2004, respectively, relate to the audit of management’s assessment that the Company maintained effective internal control over financial reporting for such years and the audit of the effectiveness of the Company’s internal control over financial reporting for such years.

Fees for audit-related services rendered by Ernst & Young LLP in 2005 and 2004 totaled $0.3 million and $0.1 million, respectively. Services provided in 2005 were in respect of due diligence related to the pending acquisition announced in February 2006 of Amcor Limited’s White Cap closures business in Europe, South America and Southeast Asia, employee benefit plan audits and examinations of certain contracts. Services provided in 2004 were in respect of employee benefit plan audits and examinations of certain contracts.

Fees for tax services rendered by Ernst & Young LLP in each of 2005 and 2004 totaled $0.1 million. Such services consisted of tax compliance services and advice.

In 2005 and 2004, Ernst & Young LLP did not render any other services to the Company.

Section 16(a) of the Exchange Act requires our directors and officers and persons holding more than ten percent of a registered class of our equity securities to file with the Securities and Exchange Commission initial reports of ownership, reports of changes in ownership and annual reports of ownership of Common Stock and other equity securities of the Company. These directors, officers and ten percent stockholders are also required to furnish us with copies of all such filed reports.

Based solely upon a review of the copies of reports furnished to us and/or representations that no reports were required, other than as set forth below we believe that all of our directors, officers and ten percent stockholders complied with all filing requirements under Section 16(a) of the Exchange Act in 2005.

On March 8, 2006, Mr. Russell F. Gervais, President of Silgan Plastics, reported the sale of 25 shares of our Common Stock and the transfer of another 25 shares of our Common Stock in a Form 5 filed with the Securities and Exchange Commission. The sale occurred on January 12, 2005 and the transfer occurred on January 13, 2005. Such transactions should have been reported on Form 4s filed within two business days after each such date.

Stockholders may submit proposals on matters appropriate for stockholder action at our annual meetings consistent with the rules and regulations adopted by the Securities and Exchange Commission. Proposals to be considered for inclusion in the Proxy Statement and the form of proxy for our annual meeting of stockholders in 2007 must be received by us at our principal executive offices not later than January , 2007. In accordance with the Exchange Act and the rules and regulations promulgated under the Exchange Act, proxies solicited by our Board of Directors will confer discretionary voting authority with respect to any proposal raised at our annual meeting of stockholders in 2007 as to which the proponent has not notified us by March , 2007. Proposals should be directed to the attention of the General Counsel, Silgan Holdings Inc., 4 Landmark Square, Stamford, Connecticut 06901.

The Board of Directors shall be divided into three {~~equal~~ }classes{,} with the term of office of the first class (the “Class I Directors”) to expire at the {~~1998~~}2007 annual meeting of stockholders, the term of office of the second class (the “Class II Directors”) to expire at the {~~1999~~}2008 annual meeting of stockholders and the term of office of the third class (the “Class III Directors”) to expire at the {~~2000~~}2009 annual meeting of stockholders.{ ~~After the filing of this Restated Certificate of Incorporation with the Secretary of State of the State of Delaware, the stockholders of the Corporation~~} There shall{ ~~elect the Board of~~} be two Class I Directors{ ~~of the Corporation at the 1997~~ }, two Class II Directors, and three Class III Directors. A director shall hold office until the annual{ meeting of stockholders or by the consent in writing, in lieu of the 1997 annual meeting of stockholders, of the holders of outstanding stock of the Corporation having not less than the minimum number of votes that would be necessary to authorize or take such action at a} meeting{ at} of stockholders of the year in which {~~all shares entitled~~}such director’s term expires and until such director’s successor shall be elected and shall qualify, subject, however, to {~~vote thereon were present and voted~~}prior death, resignation or removal from office. Any vacancies in the Board of Directors for any reason, and any directorships resulting from any increase in the number of directors, may be filled only by the Board of Directors (and not by the stockholders), acting by a majority of the directors then in office, and any directors so chosen shall hold office until the next election of the class for which such directors shall have been chosen and until their successors shall be elected and qualified. Notwithstanding the foregoing, and except as otherwise required by law, whenever the holders of any one or more series of Preferred Stock (as defined in Article SIXTH) shall have the right, voting separately as a class, to elect one or more directors of the Corporation, the terms of the director or directors elected by such holders shall expire at the next succeeding annual meeting of stockholders. Subject to the foregoing, at each annual meeting of stockholders the successors to the class of directors whose term shall then expire shall be elected to hold office for a term expiring at the third succeeding annual meeting.

B. At all meetings of the Board of Directors, a majority of the Directors then in office shall be required to constitute a quorum (“Quorum”) for the transaction of business. The approval of a majority of the entire Board of Directors, at a meeting at which a Quorum is present and acting throughout, shall be required to approve all matters submitted to the Board of Directors; provided, however, that the approval of a majority of the members of any committee of the Board of Directors shall be required to approve all matters submitted to such committee.

C. Notwithstanding any other provisions of this Amended and Restated Certificate of Incorporation or the By-Laws of the Corporation (and notwithstanding the fact that some lesser percentage may be specified by law, this Amended and Restated Certificate of Incorporation or the By-Laws of the Corporation), any director or the entire Board of Directors of the Corporation may be removed at any time, but only for cause and only by the affirmative vote of the holders of 75% or more of the outstanding shares of capital stock of the Corporation entitled to vote generally in the election of directors (considered for this purpose as one class) cast at a meeting of the stockholders called for that purpose. Notwithstanding the foregoing, and except as otherwise required by law, whenever the holders of any one or more series of Preferred Stock shall have the right, voting separately as a class, to elect one or more directors of the Corporation, the provisions of Section C of this Article shall not apply with respect to the director or directors elected by such holders of Preferred Stock.

D. There shall be an Audit Committee consisting of two or more of the directors of the Corporation, who shall perform such functions as shall be established by the Board of Directors.

8. Creation or incurrence of a lien or encumbrance on the property of the Corporation or any of its subsidiaries, except for liens relating to the Bank Financing or other minor liens, including liens for taxes or those arising by operation of law, permitted to exist under the terms of the Bank Financing.

9. Guarantees in excess of $1 million of payment by or performance of obligations of third parties other than in the ordinary course of business.

17. Entering into agreements or material transactions between the Corporation and a director or officer of the Corporation or any of {~~the following companies or their~~}its Affiliates (as defined in Article {~~NINTH~~}EIGHTH){~~: the Corporation and The Morgan Stanley Leveraged Equity Fund II, L.P., a Delaware limited partnership~~}.

18. Replacement of independent accountants for the Corporation or any of its subsidiaries.

19. Modification of significant accounting methods, practices, procedures and policies.

B. The Board of Directors of the Corporation may cause dividends to be paid to the holders of shares of Common Stock out of funds legally available for the payment of dividends by declaring an amount per share as a

C. Shares of Preferred Stock of the Corporation may be issued from time to time in one or more classes or series, each of which class or series shall have such distinctive designation or title as shall be fixed by the Board of Directors of the Corporation prior to the issuance of any shares thereof. Each such class or series of Preferred Stock shall have such voting powers, full or limited, or no voting powers, and such preferences and relative, participating, optional or other special rights and such qualifications, limitations or restrictions thereof, as shall be stated in such resolution providing for the issue of such class or series of Preferred Stock as may be adopted from time to time by the Board of Directors prior to the issuance of any shares thereof pursuant to the authority hereby expressly vested in it, all in accordance with the laws of the State of Delaware.

The payment of any amounts to any person pursuant to this Article {~~ELEVENTH~~}TENTH shall subrogate the Corporation to any right such person may have against any other person or entity.
