PROXY STATEMENT
December 21, 2004

        The enclosed proxy is solicited by and on behalf of the Board of Directors of Chase Corporation (the "Company") for the annual meeting of the Company's shareholders to be held on January 25, 2005 at 9:30 a.m., and at any adjournment thereof (the "Meeting"). The cost of solicitation will be borne by the Company. In addition to solicitation by mail, directors, officers and regular employees of the Company may solicit proxies personally or by telephone.

        The authority granted by a duly executed proxy may be revoked at any time before it is exercised by filing with the Secretary of the Company a written revocation or a duly executed proxy bearing a later date or by voting in person at the Meeting. Shareholders who attend the Meeting in person will not be deemed thereby to have revoked their proxies unless they affirmatively indicate at the meeting their intention to vote their shares in person. Unless a proxy is revoked, the shares represented thereby will be voted as directed. If no specifications are made, then proxies will be voted "for" the election of the directors nominated by the Board of Directors and "for" the proposal to amend the Company's bylaws.

        On November 30, 2004, there were 3,754,009 outstanding shares of the Company's Common Stock, $0.10 par value per share (the "Common Stock"), which is the only class of voting stock outstanding. Shareholders of record at the close of business on November 30, 2004 are entitled to vote at the Meeting. With respect to all matters that will come before the Meeting, each shareholder may cast one vote for each share of Common Stock registered in his or her name on the record date.

        A majority in interest of the Company's Common Stock outstanding and entitled to vote represented at the Meeting in person or by proxy will constitute a quorum for the transaction of business at the Meeting. Directions to withhold authority, abstentions, and broker non-votes will be counted for purposes of determining the existence of a quorum at the Meeting. A "broker non-vote" occurs when a registered broker holding a customer's shares in the name of the broker has not received voting instructions on a matter from the customer and is barred by applicable rules from exercising discretionary authority to vote on the matter and so indicates on the proxy.

        The approximate date on which this proxy statement and form of proxy will be first sent or given to shareholders is December 21, 2004. The Company's annual report for the fiscal year ended August 31, 2004 will be sent to shareholders on the same date.

Certain Transactions

        On December 10, 2003, the Company sold its Sunburst Electronics Manufacturing Solutions, Inc. subsidiary ("Sunburst") to the Edward L. Chase Revocable Trust (the "Trust") in exchange for 230,406 shares of the Company's Common Stock valued at $3.0 million. The value of the shares delivered as purchase price was calculated based upon the average closing price of the Company's Common Stock over the 20 trading days ending December 5, 2003 (the "Average Closing Price"). Concurrent with this transaction, the Company also purchased 250,000 shares of Common Stock held by the Trust at the Average Closing Price, having an aggregate purchase price of $3,255,125.

        Pursuant to the Voting Agreement dated December 26, 2002, as amended December 10, 2003, the Trustees of the Trust have agreed to vote for the nominees for director of the Company, as approved from time to time by the Company's Governance and Nominating Committee, through the annual meeting in January 2013. The Company paid the Trust $200,000 as consideration for the amendment of the Voting Agreement. The Voting Agreement requires that Andrew Chase be elected a director of the Company, unless the Trust designates a different person as its representative.

        The terms and conditions of the transactions between the Company and the Trust, including, without limitation, the purchase price for Sunburst, were determined through arm's-length negotiations between the Company and the Trust. The transactions were reviewed and approved by an independent committee of the Board of Directors following receipt of a valuation and fairness opinion completed by an independent third party valuation firm.

        As further security for Sunburst's obligations under a Revolving Demand Line of Credit Agreement in the principal amount of $2.0 million, the Company executed and delivered to the lender a Limited Guaranty dated December 2, 2003. The Limited Guaranty was limited to the repayment of no more than $500,000 towards the outstanding guaranteed obligations of Sunburst in the event that Sunburst was required to liquidate and the liquidation of Sunburst's assets did not provide sufficient funds to pay off its outstanding guaranteed amounts. Cash collateral of $500,000 related to the Limited Guaranty was held on deposit by the lender. As of August 26, 2004, the Limited Guaranty was released by the lender.

        The Company and Sunburst have also entered into a lease dated December 1, 2003 whereby the Company will lease to Sunburst, for a term of thirty-six months at a base rent of $11,900 per month, which approximates fair value, the building and land currently being occupied by Sunburst. At the end of the lease term, Sunburst maintains an option to purchase the building and land at its fair market value. Chase and Sunburst have also agreed, for a term of two years, to a mutual confidentiality, non-disclosure and non-solicitation agreement concerning Chase and Sunburst customers, suppliers and employees.

        The Trustees of the Trust have the power to vote the 882,956 shares of the Company's Common Stock held of record by the Trust on November 30, 2004 at the Meeting. In September 2002, Peter R. Chase and Andrew Chase, together with other family members, became Trustees of the Trust. Peter R. Chase resigned as a Trustee of the Trust in December 2002. Andrew Chase continues to serve as a Trustee of the Trust.

Compensation Committee Interlocks and Insider Participation

        George M. Hughes (a director) is general counsel to the Company. For his services as general counsel to the Company during the fiscal year ended August 31, 2004, the Company paid Mr. Hughes approximately $117,000.

Corporate Governance

        The Company has long believed that good corporate governance and high corporate ethics is important to ensure that the Company is managed for the long-term benefit of its shareholders.

        The Company's Board of Directors held six meetings during the fiscal year ended August 31, 2004. Each director attended at least 75% of the aggregate of all meetings of the Board of Directors and all meetings held by committees of the Board on which they served.

        The Company does not have a formal policy with respect to director attendance at annual shareholders meetings, however it does encourage all directors to attend. All directors attended last year's annual shareholders meeting held in January 2004.

        The Company has adopted the Chase Corporation Financial Code of Ethics, which is applicable to the Chief Executive Officer, Chief Financial Officer and Corporate Controller and other employees with important roles in the financial reporting process. The Chase Corporation Financial Code of Ethics is Exhibit 14 to the Company's Annual Report on Form 10-K for the fiscal year ended August 31, 2004, which was filed on November 24, 2004.

        Shareholders may contact an individual director, the Board as a group, or a specified Board committee or group, including the non-employee directors as a group, by writing to: Chase Corporation, 26 Summer Street, Bridgewater, Massachusetts 02324, Attn: Board of Directors.

        The Board of Directors has determined that the following directors are independent, as defined in the listing standards of the American Stock Exchange: Lewis P. Gack, Edward F. Hines, Jr., Ronald Levy, and Carl J. Yankowski.

Committees of the Board of Directors

        The Board has standing audit, compensation and nominating committees. All members of the committees serve at the pleasure of the Board of Directors. The functions and current membership of each committee are as follows:

        Audit Committee.    The Audit Committee recommends to the Board of Directors the engagement of the Company's independent accountants, reviews the scope and extent of their audit of the Company's financial statements, reviews the annual financial statements with the independent accountants and with management, and makes recommendations to the Board of Directors regarding the Company's policies and procedures as to internal accounting and financial controls. The members of the Audit Committee are Lewis P. Gack, Chairman, Edward F. Hines, Jr. and Carl J. Yankowski. Each member of the committee is independent, as independence for audit committee members is defined in the listing standards of the American Stock Exchange. The Board has determined that Lewis P. Gack is an audit committee financial expert as defined in the Securities and Exchange Commission regulations. The Audit Committee held six meetings during the fiscal year ended August 31, 2004. The Audit Committee operates under a written charter that is attached to this proxy statement as Exhibit B. At the next scheduled meeting of the Board of Directors of the Company in January 2005, the Board of Directors intends to adopt an amendment to the Audit Committee's charter. The Company intends to make a copy of the amended charter available through the Company's website at www.chasecorp.com following the January 2005 meeting of the Board of Directors.

---

        Compensation and Management Development Committee.    The Compensation and Management Development Committee advises the Board of Directors on matters of management, organization, and succession, recommends persons for appointments to key employee positions, and makes recommendations to the Board of Directors regarding compensation for directors, officers and key employees. The committee administers the Company's equity incentive plans, except for plans for directors who are not employees of the Company. The members of the committee are Ronald Levy, Chairman, George M. Hughes, Lewis P. Gack and Carl J. Yankowski. The committee held three meetings during the fiscal year ended August 31, 2004.

        Governance and Nominating Committee.    The Governance and Nominating Committee recommends persons for election as directors of the Company, and makes recommendations to the Board of Directors regarding the structure and membership of the various committees of the Board of Directors, including the Governance and Nominating Committee itself. The members of the Governance and Nominating Committee are George M. Hughes, Chairman, Ronald Levy and Edward F. Hines, Jr. Each member of the committee, except Mr. Hughes, is independent, as independence for nominating committee members is defined in the listing standards of the American Stock Exchange. The Governance and Nominating Committee did not hold any meetings during the fiscal year ended August 31, 2004. The Governance and Nominating Committee operates under a written charter that is available through the Company's website at www.chasecorp.com.

        George M. Hughes is a member of the Compensation and Management Development Committee and is the Chairman of the Governance and Nominating Committee. Under the rules of the American Stock Exchange, Mr. Hughes, who is the Company's general counsel, is not an independent director. The Company's Board of Directors determined at its November 22, 2004 meeting that Mr. Hughes' service on these committees was required by the best interests of the Company and its shareholders because of Mr. Hughes' long service as a director and general counsel and his familiarity with numerous aspects of the Company's compensation plans and governance procedures. Under an exception to the American Stock Exchange rules, Mr. Hughes may not serve on these committees for more than two years after October 31, 2004.

Director Nomination Process

        The Governance and Nominating Committee identifies individuals believed to be qualified to become Board members and recommends individuals to fill vacancies. In nominating candidates the Committee takes into consideration such factors as it deems appropriate, including judgment, experience, skills and personal character, as well as the needs of the Company. The Governance and Nominating Committee will consider nominees recommended by shareholders if such recommendations are made in writing to the committee. The Governance and Nominating Committee does not plan to make any differences in the manner in which the committee evaluates nominees for election as a director based on whether the nominee has been recommended by a stockholder or otherwise.

        Andrew Chase has been nominated for election as a director of the Company pursuant to a Voting Agreement dated December 26, 2002, as amended December 10, 2003, between the Company and the Edward L. Chase Revocable Trust. See "Certain Transactions."

        The Company's Bylaws provide that the Governance and Nominating Committee shall recommend for election to the Board (i) a lineal decendant or spouse of Edward L. Chase (so long as the spouse of Edward L. Chase, his issue, a trust for the benefit of his spouse and/or his issue, or his estate owns 10% or more of the outstanding voting stock of the Company) and (ii) the Chief Executive Officer of the Company.

6

---

        The Company's Bylaws also provide that the Governance and Nominating Committee shall recommend to the Board of Directors any individual or individuals for election to the Board of Directors if, after such election, a majority of the Board of Directors shall consist of "non-affiliated directors." "Non-affiliated directors" are directors (i) who are not lineal descendants of Edward L. Chase (whether by blood or adoption); (ii) who are not the spouse of Edward L. Chase or of any of his lineal descendents; (iii) who are not at the time of determination, and shall not have been at any time within three years preceding such time, officers or employees of the Company (or its predecessor) or any of its subsidiaries, affiliates or divisions; (iv) who are not at the time of determination the beneficial owners of more than 10% of the issued and outstanding shares of any class of the Company's stock; and (v) who are not officers, employees, directors or partners of any person who at the time of determination is a holder of more than 10% of the issued and outstanding shares of any class of the Company's stock.

        Also, at least a majority of the directors on the Board must be independent directors as defined in the rules of the American Stock Exchange.

PROPOSAL NUMBER 2
PROPOSAL TO AMEND THE COMPANY'S BYLAWS

Restated Company Bylaws

        The Massachusetts Legislature enacted the Massachusetts Business Corporation Act (the "MBCA") which became effective on July 1, 2004 and which supersedes the former business corporation statute. The MBCA is based on the Model Business Corporation Act, which is the basis for the corporate statutes in most other states, and is intended to give Massachusetts courts the benefit of interpretative decisions by the courts of those states. On November 22, 2004 the Board of Directors of the Company approved the Amended and Restated Bylaws attached hereto as Exhibit A, subject to shareholder approval, in order to bring the Company's existing Bylaws into compliance with certain of the provisions of the MBCA and to explicitly incorporate into the Amended and Restated Bylaws certain provisions of the MBCA which are effective by their own terms so that those sections would be set forth in the Company's Amended and Restated Bylaws.

Vote Required

        The affirmative vote of the holders of a majority of the shares of Common Stock outstanding and entitled to vote will be required to approve the proposal to amend the Company's Bylaws. Abstentions and broker non-votes will have the same effect as votes against the proposal.

Summary of Amended and Restated Bylaws

        The following is a brief summary of the Amended and Restated Bylaws. The summary, which is necessarily incomplete, is intended as a matter of convenience to help shareholders understand certain of the changes effected by the Amended and Restated Bylaws and it is recommended that shareholders read the entire text of Exhibit A. The Board of Directors recommends that the Company's shareholders approve the Amended and Restated Bylaws as submitted.

        General.    The MBCA provides the statutory office formerly referred to as the "clerk" now be redesignated as the "secretary". In addition to the changes resulting from the enactment of the MBCA, the Amended and Restated Bylaws update the Company's exiting Bylaws by making the appointment by the Board of a chairman elective, confirming that the president is the chief executive officer, and deleting certain obsolete provisions that were applicable solely to Francis M. Chase who formerly served as chairman and chief executive officer and together with his estate was formerly entitled to representation on the Company's Board of Directors.

        Article II. Meeting of Stockholders.    The amendments elaborate on notice requirements and waiver of notice provisions and expand the form of shareholder action to include certain electronic transmissions.

        Article III. Officers and Directors.    Section 4 provides that the removal of any director or directors or the entire Board of Directors may be effected only for cause by the affirmative vote of a majority of (a) the directors then in office or (b) the shares outstanding and entitled to vote in the election of directors. "Cause" shall mean only (i) conviction of a felony, (ii) declaration of unsound mind by order of court, (iii) gross dereliction of duty, (iv) commission of an action involving moral turpitude, or (v) commission of an action which constitutes intentional misconduct or a knowing violation of law if such action in either event results both in an improper substantial personal benefit and a material injury to the Company. A director may be removed by the shareholders or the directors only at a meeting called for the purpose of removing him or her, and the meeting notice must state that the purpose, or one of the purposes, of the meeting is removal of the director.

8

---

Article IV. Powers and Duties of Directors and Officers.

        Section 1 provides that all corporate power shall be exercised by or under the authority of, and the business and affairs of the Company shall be managed under the direction of, its Board of Directors. The Board of Directors may create one or more committees and appoint members of the Board of Directors to serve on them. Each committee may have one or more members, who serve at the pleasure of the Board of Directors. The creation of a committee and appointment of members to it must be approved by a majority of all the directors in office when the action is taken. To the extent specified by the Board of Directors and to the extent permitted by law, each committee may exercise the authority of the Board of Directors.

        Section 7 relating to the Nominating Committee provides that the Nominating Committee shall from time to time prepare and propose to the directors its charter, which shall comply with all applicable requirements of the Securities and Exchange Commission and any stock exchange on which the Company's shares may be listed.

        Section 8 defines the general standard of conduct for directors in accordance with the MBCA. Comments by the drafters of the MBCA state that the standard focuses on the manner in which the director performs his duties, not the correctness of his decisions, and by emphasizing the decision-making process, not the decision itself. The drafters point out that although some decisions may turn out to be unwise or the result of a mistake in judgment, it is unreasonable to reexamine these decisions with the benefit of hindsight. A director, state the drafters, is not liable for injury or damage caused by his decision, no matter how unwise or mistaken it may turn out to be, if in performing his duties, he has met the requirements of the statute.

        Section 8 provides that:

        (a)   A director shall discharge his or her duties as a director, including his or her duties as a member of a committee: (1) in good faith; (2) with the care that a person in a like position would reasonably believe appropriate under similar circumstances; and (3) in a manner the director reasonably believes to be in the best interests of the corporation. In determining what the director reasonably believes to be in the best interests of the corporation, a director may consider the interests of the corporation's employees, suppliers, creditors and customers, the economy of the state, the region and the nation, community and societal considerations, and the long-term and short-term interests of the corporation and its shareholders, including the possibility that these interests may be best served by the continued independence of the corporation.

        (b)   In discharging his or her duties, a director who does not have knowledge that makes reliance unwarranted is entitled to rely on information, opinions, reports, or statements, including financial statements and other financial data, if prepared or presented by: (1) one or more officers or employees of the corporation whom the director reasonably believes to be reliable and competent with respect to the information, opinions, reports or statements presented; (2) legal counsel, public accountants, or other persons retained by the corporation, as to matters involving skills or expertise the director reasonably believes are matters (i) within the particular person's professional or expert competence or (ii) as to which the particular person merits confidence; or (3) a committee of the board of directors of which the director is not a member if the director reasonably believes the committee merits confidence.

        (c)   A director is not liable for any action taken as a director, or any failure to take any action, if he or she performed the duties of his or her office in compliance with this Section.

        Section 9 deals with "conflict of interest" transactions by a director and the Company which are defined as transactions in which the director has a material interest either directly or indirectly. The MBCA rejects the common law view of some states other than Massachusetts that all conflict of interest transactions entered into by the directors are voidable at the option of the Company without regard to the fairness of the transaction or the manner in which the transaction was approved.

9

---

        Section 9 provides that:

        (a)   A conflict of interest transaction is a transaction with the corporation in which a director of the corporation has a material direct or indirect interest. A conflict of interest transaction is not voidable by the corporation solely because of the director's interest in the transaction if any one of the following is true:

        (1)   the material facts of the transaction and the director's interest were disclosed or known to the board of directors or a committee of the board and the board or committee authorized, approved, or ratified the transaction;

        (2)   the material facts of the transaction and the director's interest were disclosed or known to the shareholders entitled to vote and they authorized, approved, or ratified the transaction; or

        (3)   the transaction was fair to the corporation.

        (b)   For purposes of this Section, and without limiting the interests that may create conflict of interest transactions, a director of the corporation has an indirect interest in a transaction if: (1) another entity in which he or she has a material financial interest or in which he or she is a general partner is a party to the transaction; or (2) another entity of which he or she is a director, officer, or trustee or in which he or she holds another position is a party to the transaction and the transaction is or should be considered by the board of directors of the corporation.

        (c)   For purposes of clause (1) of subsection (a), a conflict of interest transaction is authorized, approved, or ratified if it receives the affirmative vote of a majority of the directors on the board of directors (or on the committee) who have no direct or indirect interest in the transaction, but a transaction may not be authorized, approved, or ratified under this Section by a single director. If a majority of the directors who have no direct or indirect interest in the transaction vote to authorize, approve, or ratify the transaction, a quorum is present for the purpose of taking action under this Section. The presence of, or a vote cast by, a director with a direct or indirect interest in the transaction does not affect the validity of any action taken under clause (1) of subsection (a) if the transaction is otherwise authorized, approved, or ratified as provided in that subsection.

        Section 10 sets forth standards of conduct for officers of the corporation and provides that:

        An officer shall discharge his or her duties: (a) in good faith; (b) with the care that a person in a like position would reasonably exercise under similar circumstances; and (c) in a manner the officer reasonably believes to be in the best interests of the corporation. In discharging his or her duties, an officer, who does not have knowledge that makes reliance unwarranted, is entitled to rely on information, opinions, reports, or statements, including financial statements and other financial data, if prepared or presented by: (1) one or more officers or employees of the corporation whom the officer reasonably believes to be reliable and competent with respect to the information, opinions, reports or statements presented; or (2) legal counsel, public accountants, or other persons retained by the corporation as to matters involving skills or expertise the officer reasonably believes are matters (i) within the particular person's professional or expert competence or (ii) as to which the particular person merits confidence. An officer shall not be liable to the corporation or its shareholders for any decision to take or not to take any action taken, or any failure to take any action, as an officer, if the duties of the officer are performed in compliance with this Section.

        Article V. Meeting of the Directors.    Amendments to this Article include changes to the mechanics of calling director meetings. Section 4 further provides that:

        A director who is present at a meeting of the board of directors or a committee of the board when corporate action is taken is considered to have assented to the action taken unless: (a) he or she objects at the beginning of the meeting, or promptly upon his or her arrival, to holding it or transacting business at the meeting; (b) his or her dissent or abstention from the action taken is entered in the

10

---

minutes of the meeting; or (c) he or she delivers written notice of his or her dissent or abstention to the presiding officer of the meeting before its adjournment or to the corporation immediately after adjournment of the meeting. The right of dissent or abstention is not available to a director who votes in favor of the action taken.

        Article VI. Corporate Records.    Section 1 of this article describes the records that the Company must keep, the form in which they may be maintained and, to a limited extent, where the records must be kept:

        (a)   The corporation shall keep as permanent records minutes of all meetings of its shareholders and board of directors, a record of all actions taken by the shareholders or board of directors without a meeting, and a record of all actions taken by a committee of the board of directors in place of the board on behalf of the corporation. The corporation shall maintain appropriate accounting records. The corporation or its agent shall maintain a record of its shareholders, in a form that permits preparation of a list of the names and addresses of all shareholders, in alphabetical order by class of shares showing the number and class of shares held by each. The corporation shall maintain its records in written form or in another form capable of conversion into written form within a reasonable time.

        (b)   The corporation shall keep within the Commonwealth of Massachusetts a copy of the following records at its principal office or an office of its transfer agent or of its Secretary or Assistant Secretary or of its registered agent:

        (i)    its Articles or Restated Articles of Organization and all amendments to them currently in effect;

        (ii)   its Bylaws or restated Bylaws and all amendments to them currently in effect;

        (iii)  resolutions adopted by its board of directors creating one or more classes or series of shares, and fixing their relative rights, preferences, and limitations, if shares issued pursuant to those resolutions are outstanding;

        (iv)  the minutes of all shareholders' meetings, and records of all action taken by shareholders without a meeting, for the past three years;

        (v)   all written communications to shareholders generally within the past three years, including the financial statements furnished under Section 16.20 of the MBCA for the past three years;

        (vi)  a list of the names and business addresses of its current directors and officers; and

        (vii) its most recent annual report delivered to the Massachusetts Secretary of State.

        Sections 2 and 3 provide for a shareholder right of inspection of corporate records. The drafters of the MBCA state that the rights set forth in Sections 2 and 3 are independent of the right to inspect a shareholder list prior to a meeting, the right of discovery in litigation, and any "common law" right to inspect that may exist under judicially-created law:

        Section 2. Inspection of Records by Shareholders.

        (a)   A shareholder is entitled to inspect and copy, during regular business hours at the office where they are maintained pursuant to Section 1(b) of this Article, copies of any of the records of the corporation described in said Section if he or she gives the corporation written notice of his or her demand at least five business days before the date on which he or she wishes to inspect and copy.

        (b)   A shareholder is entitled to inspect and copy, during regular business hours at a reasonable location specified by the corporation, any of the following records of the corporation if the shareholder

11

---

meets the requirements of subsection (c) and gives the corporation written notice of his or her demand at least five business days before the date on which he or she wishes to inspect and copy:

        (1)   excerpts from minutes reflecting action taken at any meeting of the board of directors, records of any action of a committee of the board while acting in place of the board on behalf of the corporation, minutes of any meeting of the shareholders, and records of action taken by the shareholders or board of directors without a meeting, to the extent not subject to inspection under subsection (a) of this Section;

        (2)   accounting records of the corporation, but if the financial statements of the corporation are audited by a certified public accountant, inspection shall be limited to the financial statements and the supporting schedules reasonably necessary to verify any line item on those statements; and

        (3)   the record of shareholders described in Section 1(a) of this Article.

        (c)   A shareholder may inspect and copy the records described in subsection (b) only if:

        (1)   his or her demand is made in good faith and for a proper purpose;

        (2)   he or she describes with reasonable particularity his or her purpose and the records he or she desires to inspect;

        (3)   the records are directly connected with his or her purpose; and

        (4)   the corporation shall not have determined in good faith that disclosure of the records sought would adversely affect the corporation in the conduct of its business or, in the case of a public corporation, constitute material non-public information at the time when the shareholder's notice of demand to inspect and copy is received by the corporation.

        (d)   For purposes of this Section, "shareholder" includes a beneficial owner whose shares are held in a voting trust or by a nominee on his or her behalf.

        Section 3. Scope of Inspection Right.

        (a)   A shareholder's agent or attorney has the same inspection and copying rights as the shareholder represented.

        (b)   The corporation may, if reasonable, satisfy the right of a shareholder to copy records under Section 2 of this Article by furnishing to the shareholder copies by photocopy or other means chosen by the corporation including copies furnished through an electronic transmission.

        (c)   The corporation may impose a reasonable charge, covering the costs of labor, material, transmission and delivery, for copies of any documents provided to the shareholder. The charge may not exceed the estimated cost of production, reproduction, transmission or delivery of the records.

        (d)   The corporation may comply at its expense, with a shareholder's demand to inspect the record of shareholders under Section 2(b)(3) of this Article by providing the shareholder with a list of shareholders that was compiled no earlier than the date of the shareholder's demand.

        (e)   The corporation may impose reasonable restrictions on the use or distribution of records by the demanding shareholder.

        Article IX. Indemnification.    Article IX provides extensive provisions regarding the indemnification by the Company of its directors and officers:

        Section 1. Definitions.    In this Article the following words have the following meanings unless the context requires otherwise:

        "Corporation", includes any domestic or foreign predecessor entity of the corporation in a merger.

12

---

        "Director" or "officer", an individual who is or was a director or officer, respectively, of the Corporation or who, while a director or officer of the Corporation, is or was serving at the Corporation's request as a director, officer, partner, trustee, employee, or agent of another domestic or foreign corporation, partnership, joint venture, trust, employee benefit plan, or other entity. A director or officer is considered to be serving an employee benefit plan at the Corporation's request if his or her duties to the Corporation also impose duties on, or otherwise involve services by, him or her to the plan or to participants in or beneficiaries of the plan. "Director" or "officer" includes, unless the context requires otherwise, the estate or personal representative of a director or officer.

        "Disinterested Director", a director who, at the time of a vote or selection referred to in Section 4 of this Article, is not (i) a party to the proceeding, or (ii) an individual having a familial, financial, professional, or employment relationship with the director whose indemnification or advance for expenses is the subject of the decision being made, which relationship would, in the circumstances, reasonably be expected to exert an influence on the director's judgment when voting on the decision being made.

        "Expenses", includes counsel fees.

        "Liability", the obligation to pay a judgment, settlement, penalty, fine including an excise tax assessed with respect to an employee benefit plan, or reasonable expenses incurred with respect to a proceeding.

        "Party", an individual who was, is, or is threatened to be made, a defendant or respondent in a proceeding.

        "Proceeding", any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, arbitrative, or investigative and whether formal or informal.

Section 2. Indemnification of Directors and Officers.

        (a)   Except as otherwise provided in this Section, the Corporation shall indemnify to the fullest extent permitted by law an individual who is a party to a proceeding because he or she is a director or officer against liability incurred in the proceeding if: (1) (i) he or she conducted himself or herself in good faith; and (ii) he or she reasonably believed that his or her conduct was in the best interests of the Corporation or that his or her conduct was at least not opposed to the best interests of the Corporation; and (iii) in the case of any criminal proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful; or (2) he or she engaged in conduct for which he or she shall not be liable under a provision of the Articles of Organization authorized by Section 2.02(b)(4) of the MBCA or any successor provision to such Section.

        (b)   A director's or officer's conduct with respect to an employee benefit plan for a purpose he or she reasonably believed to be in the interests of the participants in, and the beneficiaries of, the plan is conduct that satisfies the requirement that his or her conduct was at least not opposed to the best interests of the Corporation.

        (c)   The termination of a proceeding by judgment, order, settlement, or conviction, or upon a plea of nolo contendere or its equivalent, is not, of itself, determinative that the director or officer did not meet the relevant standard of conduct described in this Section.

        (d)   Unless ordered by a court, the Corporation may not indemnify a director or officer under this Section if his or her conduct did not satisfy the standards set forth in subsection (a) or subsection (b).

        Section 3. Advance for Expenses.    The Corporation shall, before final disposition of a proceeding, advance funds to pay for or reimburse the reasonable expenses incurred by a director or officer who is a party to a proceeding because he or she is a director or officer if he or she delivers to the Corporation:

13

---

        (a)   a written affirmation of his or her good faith belief that he or she has met the relevant standard of conduct described in Section 2 of this Article or that the proceeding involves conduct for which liability has been eliminated under a provision of the Articles of Organization as authorized by Section 2.02(b)(4) of the MBCA or any successor provision to such Section; and

        (b)   his or her written undertaking to repay any funds advanced if he or she is not wholly successful, on the merits or otherwise, in the defense of such proceeding and it is ultimately determined pursuant to Section 4 of this Article or by a court of competent jurisdiction that he or she has not met the relevant standard of conduct described in Section 2 of this Article. Such undertaking must be an unlimited general obligation of the director or officer but need not be secured and shall be accepted without reference to the financial ability of the director or officer to make repayment.

        Section 4. Determination of Indemnification.    The determination of whether a director has met the relevant standard of conduct set forth in Section 2 shall be made:

        (a)   if there are two or more disinterested directors, by the Board of Directors by a majority vote of all the disinterested directors, a majority of whom shall for such purpose constitute a quorum, or by a majority of the members of a committee of two or more disinterested directors appointed by vote;

        (b)   by special legal counsel (1) selected in the manner prescribed in clause (a); or (2) if there are fewer than two disinterested directors, selected by the Board of Directors, in which selection directors who do not qualify as disinterested directors may participate; or

        (c)   by the shareholders, but shares owned by or voted under the control of a director who at the time does not qualify as a disinterested director may not be voted on the determination.

Section 5. Notification and Defense of Claim; Settlements.

        (a)   In addition to and without limiting the foregoing provisions of this Article and except to the extent otherwise required by law, it shall be a condition of the Corporation's obligation to indemnify under Section 2 of this Article (in addition to any other condition provide in these Bylaws or by law) that the person asserting, or proposing to assert, the right to be indemnified, must notify the Corporation in writing as soon as practicable of any action, suit, proceeding or investigation involving such person for which indemnity will or could be sought, but the failure to so notify shall not affect the Corporation's objection to indemnify except to the extent the Corporation is adversely affected thereby. With respect to any proceeding of which the Corporation is so notified, the Corporation will be entitled to participate therein at its own expense and/or to assume the defense thereof at its own expense, with legal counsel reasonably acceptable to such person. After notice from the Corporation to such person of its election so to assume such defense, the Corporation shall not be liable to such person for any legal or other expenses subsequently incurred by such person in connection with such action, suit, proceeding or investigation other than as provided below in this subsection (a). Such person shall have the right to employ his or her own counsel in connection with such action, suit, proceeding or investigation, but the fees and expenses of such counsel incurred after notice from the Corporation of its assumption of the defense thereof shall be at the expense of such person unless (1) the employment of counsel by such person has been authorized by the Corporation, (2) counsel to such person shall have reasonably concluded that there may be a conflict of interest or position on any significant issue between the Corporation and such person in the conduct of the defense of such action, suit, proceeding or investigation or (3) the Corporation shall not in fact have employed counsel to assume the defense of such action, suit, proceeding or investigation, in each of which cases the fees and expenses of counsel for such person shall be at the expense of the Corporation, except as otherwise expressly provided by this Article. The Corporation shall not be entitled, without the consent of such person, to assume the defense of any claim brought by or in the right of the Corporation or as to which counsel for such person shall have reasonably made the conclusion provided for in clause (2) above.

14

---

        (b)   The Corporation shall not be required to indemnify such person under this Article for any amounts paid in settlement of any proceeding unless authorized in the same manner as the determination that indemnification is permissible under Section 4 of this Article, except that if there are fewer than two disinterested directors, authorization of indemnification shall be made by the Board of Directors, in which authorization directors who do not qualify as disinterested directors may participate. The Corporation shall not settle any action, suit, proceeding or investigation in any manner which would impose any penalty or limitation on such person without such person's written consent. Neither the Corporation nor such person will unreasonably withhold their consent to any proposed settlement.

        Section 6. Insurance.    The Corporation may purchase and maintain insurance on behalf of an individual who is a director or officer of the Corporation, or who, while a director or officer of the Corporation, serves at the Corporation's request as a director, officer, partner, trustee, employee, or agent of another domestic or foreign corporation, partnership, joint venture, trust, employee benefit plan, or other entity, against liability asserted against or incurred by him or her in that capacity or arising from his or her status as a director or officer, whether or not the Corporation would have power to indemnify or advance expenses to him or her against the same liability under this Article.

Section 7. Application of this Article.

        (a)   The Corporation shall not be obligated to indemnify or advance expenses to a director or officer of a predecessor of the Corporation, pertaining to conduct with respect to the predecessor, unless otherwise specifically provided.

        (b)   This Article shall not limit the Corporation's power to (1) pay or reimburse expenses incurred by a director or an officer in connection with his or her appearance as a witness in a proceeding at a time when he or she is not a party or (2) indemnify, advance expenses to or provide or maintain insurance on behalf of an employee or agent.

        (c)   The indemnification and advancement of expenses provided by, or granted pursuant to, this Article shall not be considered exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled.

        (d)   Each person who is or becomes a director or officer shall be deemed to have served or to have continued to serve in such capacity in reliance upon the indemnity provided for in this Article. All rights to indemnification under this Article shall be deemed to be provided by a contract between the Corporation and the person who serves gas a director or officer of the Corporation at any time while these Bylaws and the relevant provisions of the MBCA are in effect. Any repeal or modification thereof shall not affect any rights or obligations then existing.

        (e)   If the laws of the Commonwealth of Massachusetts are hereafter amended from time to time to increase the scope of permitted indemnification, indemnification hereunder shall be provided to the fullest extent permitted or required by any such amendment.

Other Compensation Matters

        Executive Severance and Change in Control Agreement.    In October 1994, the Company and Peter R. Chase (the "Executive") entered into an Executive Severance Agreement. Under the terms of the agreement, if the Executive's employment is terminated within 24 months after the occurrence of a change in control of the Company, then the Executive shall receive the following benefits.

•

If terminated for cause, the Executive shall be entitled to his salary through the period ending with the date of such termination and any accrued benefits.



•

In case of death, disability or retirement, the Executive shall be entitled to such benefits as may be provided to him pursuant to the Company's employee benefit plans.



•

If terminated without cause or if the Executive resigns for good reason, the Executive shall be entitled to the following benefits:



a.

Severance pay in an amount equal to two times the greater of his annual salary in effect prior to the change in control or his annual salary in effect immediately prior to termination.



b.

Health insurance, dental insurance and group term life insurance for a period ending on the earlier of the commencement date of equivalent benefits from a new employer or his normal retirement date, provided the Executive continues to pay an amount equal to the employee's share of contributions.



c.

If the Executive is 55 or older on the date of termination, the Executive will continue to receive, until his normal retirement date, service credit under the Company's pension plans and any supplemental arrangement.



d.

At the request of the Executive, the Company shall pay the reasonable costs of an out-placement service for up to two years.

        2001 Senior Management Stock Plan.    The 2001 Senior Management Stock Plan (the "Management Plan") reserves 750,000 shares of the Company's Common Stock for option grants to senior management, including the named executive officers. Under the terms of the Management Plan, options may be granted in the form of incentive stock options, non-qualified stock options and restricted stock. Options granted under the Management Plan generally vest over a period ranging from

17

---

three to five years and expire after ten years. The Company did not grant any options under the Management Plan to the named executive officers during fiscal 2004. As of August 31, 2004 there were 210,000 shares of the Company's Common Stock available for future issuance under the Management Plan.

        Non-Qualified Retirement Savings Plan.    The Company maintains a Non-Qualified Retirement Savings Plan covering selected employees, including the named executive officers. Participants may elect to defer a portion of their compensation for future payment in accordance with the terms of the plan.

        Pension Plan.    The Company maintains a tax-qualified defined benefit pension plan and a non-qualified excess benefit plan. The qualified pension plan covers substantially all of the Company's employees who have attained the age of 21 and have completed six months of service. The excess benefit plan, which is part of the Employee's Supplemental Pension and Savings Plan, covers those employees of the Company that from time to time may be designated by the Board of Directors. Currently, only the Company's Chief Executive Officer has been designated by the Board of Directors as being covered by the excess benefit plan. Benefits under the qualified pension plan are determined based on final average base earnings (subject to Code-imposed limits on covered compensation and excluding bonuses, overtime, and other extraordinary amounts) and total years service with the Company (up to a maximum of 40 years). Benefits under the excess benefit plan are determined based on final average earnings (including base salary and bonuses) and total years of service with the Company. Benefits are payable upon the retirement of a participant at age 65, or upon the fifth anniversary of employment, if later, or earlier if the participant is at least 55 years old and has completed at least five years of service. The plan offers the option for a participant to receive a lump sum distribution upon attainment of age 65 and five years of employment even if the employee elects to remain actively employed. Benefits may be paid in a variety of forms, including a lump sum, at the election of the participant.

        The following Tables 1 and 2 show estimates of aggregate annual benefits payable under the qualified pension plan and excess benefit plan upon retirement at age 65 or upon the fifth anniversary of employment, if later. Table 1 relates to those participants who were employed prior to May 1, 1995 or are covered by a collective bargaining agreement and are in the specified compensation and years-of-service classifications before an offset of 0.6% of covered compensation at the time of retirement times the number of years-of-service (up to a maximum of 35 years).

        Table 2 relates to those participants who became employed on or after May 1, 1995 and are not covered by a collective bargaining agreement and are in the specified compensation and years-of-service classifications before any offset of 0.3% of covered compensation at the time of retirement times the number of years-of-service (up to a maximum of 35 years).

*

As required by Section 415 of the Code, qualified plan payments may not provide annual benefits exceeding a maximum amount ($165,000 for 2004 and $160,000 for 2003). For employees who are covered under the excess benefit plan, amounts above this maximum will be paid under the terms of the excess benefit plan up to the amounts shown in the table above. Pursuant to Section 401(a)(17) of the Code, annual compensation in excess of $205,000 for 2004 and $200,000 for 2003 cannot be taken into account in determining qualified plan benefits.

Mr. Chase and Mr. Chadwick have approximately 33 and 16 years of service, respectively.

        Compensation of Directors.    Directors who are not employees and are part of a committee of the Company are paid an annual retainer of $25,000. Any non-employee director who is not sitting on any committee is paid an annual retainer of $18,000. The retainer covers all meetings and any director's status as a chairperson.

        2001 Non-Employee Director Stock Option Plan.    The 2001 Non-Employee Director Stock Option Plan (the "Director Plan") reserves 90,000 shares of the Company's Common Stock for option grants to directors. Options granted under the Director Plan will be issued as non-qualified stock options. Options granted under the Director Plan generally vest over a period ranging from three to five years and expire after ten years. The Company did not grant any options under the Director Plan during fiscal 2004. As of August 31, 2004 there were 15,000 shares of the Company's Common Stock available for future issuance under the Director Plan.

        Non-Qualified Retirement Savings Plan for the Board of Directors.    The Company maintains the Non-Qualified Retirement Savings Plan for the Board of Directors. Participants may elect to defer a portion of their compensation for future payment in accordance with the terms of the plan.

        George M. Hughes also receives compensation for his services as general counsel to the Company.

Compensation and Management Development Committee Report on Executive Compensation

        Recommendations on compensation for the Company's executive officers are made by the Compensation and Management Development Committee of the Board of Directors (the "Committee"). A majority of the Committee is composed of independent non-employee directors who have no interlocking directorships as defined by the Securities and Exchange Commission. Committee decisions are reviewed and approved by the full Board of Directors.

        The Company's executive compensation program is designed to accomplish the following objectives:

•

Reward key executives at levels that are competitive with those of similar comparative companies.



•

Provide incentives that are directly linked to the achievement of Company strategies, profits and enhancements of shareholder value.



•

Ensure that the objectives for corporate and business unit performance are established and measured.



•

Attract and retain executives who have the capabilities needed to ensure proper growth and profitability.

        The Company, acting through the Committee, employs three programs to compensate its senior management. These include an annual base salary program, a contingent compensation program that is based on selected financial performance measures and a stock option plan. Following is a description of the manner in which each program was administered during the last fiscal year, which includes an explanation of the rationale for the compensation paid to the Chief Executive Officer.

Annual Base Salary Program

        Salary ranges are established for executive positions, including the named executive officers, with range midpoints equal to the median salary determined from appropriate comparative survey data provided by an independent consultant. The actual salary of each individual holding an executive position is determined using the established salary ranges and also by taking into consideration the individual's qualifications, sustained performance and level of responsibility, each as evaluated by the Committee. Adjustments in base salary are made after an analysis of the foregoing factors and any external trends in compensation reflected in the survey data discussed above.

        The base salary for Peter R. Chase was set by the Committee using the same policies and criteria used for other executive officers of the Company. His base salary for the fiscal year ended 2004 was set at about the median salary level for chief executive officers in the Company's industry as reflected in the comparative survey data and adjusted based on the Committee's evaluation of the additional criteria discussed above. While corporate performance measures are used in determining bonuses, such corporate performance measures are not considered by the Committee in determining Mr. Chase's base salary.

Contingent Compensation Program

        Under the Company's contingent compensation program, each executive officer, including the named executive officers, was eligible to earn additional contingent compensation in an amount equal to a designated percentage of annual base salary. In the 2004 fiscal year, the target percentage for achieving targeted operating profits set with reference to the three prior fiscal years was 50% of annual base salary for the Chief Executive Officer and 30% for the Chief Financial Officer. Potential incentive earnings could range from 0% to 100% of annual base salary, depending upon whether the Company's actual performance during the year met, exceeded or fell short of the operating profit goals. The

20

---

Company exceeded the operating profit goals established for payment of the targeted incentive compensation in fiscal year 2004; therefore, using the plan as a basis, the Chief Executive Officer and the Chief Financial Officer received contingent compensation in an amount equal to 73% and 62% respectively, of their annual base salary for the last fiscal year.

Senior Management Stock Plan

        The Committee and Board of Directors, with the assistance of an independent compensation consultant, have developed long term equity incentive plans for the Company. The 2001 Senior Management Stock Plan was designed in part to retain and provide incentives to the Company's Chief Executive and Chief Financial Officers as well as other senior members of the Company's management. The Committee believes that these executives are in a position to make the most significant contribution to the Company's future success. The program is designed to recognize significant contributions and provide longer-term incentives to increase shareholder value. All options granted by the Company to its executives have been granted at an exercise price equal to or in excess of the market price of the Company's Common Stock on the date of grant. Consequently, these stock options will have value only if the price of the Company's Common Stock increases.

Performance Graph

        The following line graph compares the yearly percentage change in the Company's cumulative total shareholder return on the Common Stock for the last five fiscal years with the cumulative total return on the Standard & Poor's 500 Stock Index ("the S&P 500 Index"), and a composite peer index that is weighted by market equity capitalization on companies with the Chase Corporation Standard Industrial Classification (S.I.C.) code (the "Peer Group Index"). The companies included in the Peer Group Index are American Biltrite, Inc., Lamson & Sessions Co., Plymouth Rubber Company Inc., MacDermid Inc., Bairnco Corp., and Flamemaster Corp. Cumulative total returns are calculated assuming that $100 was invested August 31, 1999 in each of the Common Stock, the S&P 500 and the Peer Group Index, and that all dividends were reinvested.

The Audit Committee, in accordance with its written charter (See Exhibit B), oversees the Company's financial reporting process on behalf of the Board of Directors. Management has the primary responsibility for the financial statements and the reporting process including the systems of internal controls. In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed the audited financial statements for the fiscal year ended August 31, 2004 with management including a discussion of the quality, not just the acceptability of the Company's accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements.

Independent Registered Public Accounting Firm

        Livingston & Haynes, P.C. served as the Company's independent auditors for the fiscal years ended August 31, 2003 and 2002. The Company selected the firm of PricewaterhouseCoopers LLP to serve as its Independent Registered Public Accounting Firm for the fiscal year ended August 31, 2004.

        Livingston & Haynes, P.C.'s reports on the Company's financial statements for the fiscal years ended August 31, 2003 and 2002 did not contain an adverse opinion or disclaimer of opinion, nor were such reports qualified or modified as to uncertainty, audit scope, or accounting principles. During the Company's fiscal years ended August 31, 2003 and 2002 and the subsequent interim period through December 15, 2003, there were no disagreements with Livingston & Haynes, P.C. on any matter of accounting principles or practices, financial statement disclosures or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Livingston & Haynes, P.C., would have caused them to make reference to the subject matter of the disagreements in connection with their reports.

Section 16(a) Beneficial Ownership Reporting Compliance

        The Company's directors and executive officers file reports with the SEC indicating the number of shares of any class of the Company's equity securities that they owned when they became a director or an executive officer and, after that, any changes in their ownership of the Company's equity securities. Based solely upon a review of these reports on Forms 3, 4 and 5 and amendments thereto furnished to the Company with respect to its most recent fiscal year, the Company believes that all reporting persons filed on a timely basis the reports required by Section 16(a) of the Securities Exchange Act of 1934, as amended, during the most recent fiscal year, except for the following: (a) a late Form 4 was filed for Peter R. Chase on October 24, 2004 and (b) a late Form 3 was filed on December 9, 2004 for each of Andrew Chase and Carl J. Yankowski, who were elected to the Board on January 27, 2004.

In determining what the director reasonably believes to be in the best interests of the corporation, a director may consider the interests of the corporation's employees, suppliers, creditors and customers, the economy of the state, the region and the nation, community and societal considerations, and the long-term and short-term interests of the corporation and its shareholders, including the possibility that these interests may be best served by the continued independence of the corporation.

        Section 9.    Conflict of Interest.    

        (a)   A conflict of interest transaction is a transaction with the corporation in which a director of the corporation has a material direct or indirect interest. A conflict of interest transaction is not voidable by the corporation solely because of the director's interest in the transaction if any one of the following is true:

        (1)   the material facts of the transaction and the director's interest were disclosed or known to the board of directors or a committee of the board and the board or committee authorized, approved, or ratified the transaction;

        (2)   the material facts of the transaction and the director's interest were disclosed or known to the shareholders entitled to vote and they authorized, approved, or ratified the transaction; or

        (3)   the transaction was fair to the corporation.

        (b)   For purposes of this Section, and without limiting the interests that may create conflict of interest transactions, a director of the corporation has an indirect interest in a transaction if: (1) another entity in which he or she has a material financial interest or in which he or she is a general partner is a party to the transaction; or (2) another entity of which he or she is a director, officer, or trustee or in which he or she holds another position is a party to the transaction and the transaction is or should be considered by the board of directors of the corporation.

        (c)   For purposes of clause (1) of subsection (a), a conflict of interest transaction is authorized, approved, or ratified if it receives the affirmative vote of a majority of the directors on the board of directors (or on the committee) who have no direct or indirect interest in the transaction, but a transaction may not be authorized, approved, or ratified under this Section by a single director. If a majority of the directors who have no direct or indirect interest in the transaction vote to authorize, approve, or ratify the transaction, a quorum is present for the purpose of taking action under this Section. The presence of, or a vote cast by, a director with a direct or indirect interest in the transaction does not affect the validity of any action taken under clause (1) of subsection (a) if the transaction is otherwise authorized, approved, or ratified as provided in that subsection.

        Section 10.    Standards Of Conduct For Officers.    An officer shall discharge his or her duties: (a) in good faith; (b) with the care that a person in a like position would reasonably exercise under similar circumstances; and (c) in a manner the officer reasonably believes to be in the best interests of the corporation. In discharging his or her duties, an officer, who does not have knowledge that makes reliance unwarranted, is entitled to rely on information, opinions, reports, or statements, including financial statements and other financial data, if prepared or presented by: (1) one or more officers or employees of the corporation whom the officer reasonably believes to be reliable and competent with respect to the information, opinions, reports or statements presented; or (2) legal counsel, public accountants, or other persons retained by the corporation as to matters involving skills or expertise the officer reasonably believes are matters (i) within the particular person's professional or expert competence or (ii) as to which the particular person merits confidence. An officer shall not be liable to the corporation or its shareholders for any decision to take or not to take any action taken, or any failure to take any action, as an officer, if the duties of the officer are performed in compliance with this Section.

        (3)   the records are directly connected with his or her purpose; and

        (4)   the corporation shall not have determined in good faith that disclosure of the records sought would adversely affect the corporation in the conduct of its business or, in the case of a public corporation, constitute material non-public information at the time when the shareholder's notice of demand to inspect and copy is received by the corporation.

        (d)   For purposes of this Section, "shareholder" includes a beneficial owner whose shares are held in a voting trust or by a nominee on his or her behalf.

        (c)   The corporation may impose a reasonable charge, covering the costs of labor, material, transmission and delivery, for copies of any documents provided to the shareholder. The charge may not exceed the estimated cost of production, reproduction, transmission or delivery of the records.

        (d)   The corporation may comply at its expense, with a shareholder's demand to inspect the record of shareholders under Section 2(b)(3) of this Article by providing the shareholder with a list of shareholders that was compiled no earlier than the date of the shareholder's demand.

ARTICLE IX
Indemnification.

        Section 1.    Definitions.    In this Article the following words shall have the following meanings unless the context requires otherwise:

        "Corporation", includes any domestic or foreign predecessor entity of the corporation in a merger.

        "Director" or "officer", an individual who is or was a director or officer, respectively, of the corporation or who, while a director or officer of the corporation, is or was serving at the corporation's request as a director, officer, partner, trustee, employee, or agent of another domestic or foreign corporation, partnership, joint venture, trust, employee benefit plan, or other entity. A director or officer is considered to be serving an employee benefit plan at the corporation's request if his or her duties to the corporation also impose duties on, or otherwise involve services by, him or her to the plan or to participants in or beneficiaries of the plan. "Director" or "officer" includes, unless the context requires otherwise, the estate or personal representative of a director or officer.

        "Disinterested Director", a director who, at the time of a vote or selection referred to in Section 4 of this Article, is not (i) a party to the proceeding, or (ii) an individual having a familial, financial, professional, or employment relationship with the director whose indemnification or advance for expenses is the subject of the decision being made, which relationship would, in the circumstances, reasonably be expected to exert an influence on the director's judgment when voting on the decision being made.

        "Expenses", includes counsel fees.

        "Liability", the obligation to pay a judgment, settlement, penalty, fine including an excise tax assessed with respect to an employee benefit plan, or reasonable expenses incurred with respect to a proceeding.

        "Party", an individual who was, is, or is threatened to be made, a defendant or respondent in a proceeding.

        "Proceeding", any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, arbitrative, or investigative and whether formal or informal.¹

        Section 2.    Indemnification of Directors and Officers.    

        (a)   Except as otherwise provided in this Section, the corporation shall indemnify to the fullest extent permitted by law an individual who is a party to a proceeding because he or she is a director or officer against liability incurred in the proceeding if: (1) (i) he or she conducted himself or herself in good faith; and (ii) he or she reasonably believed that his or her conduct was in the best interests of the corporation or that his or her conduct was at least not opposed to the best interests of the corporation; and (iii) in the case of any criminal proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful; or (2) he or she engaged in conduct for which he or she shall not be liable under a provision of the Articles of Organization authorized by Section 2.02(b)(4) of the MBCA or any successor provision to such Section.

        (b)   A director's or officer's conduct with respect to an employee benefit plan for a purpose he or she reasonably believed to be in the interests of the participants in, and the beneficiaries of, the plan is conduct that satisfies the requirement that his or her conduct was at least not opposed to the best interests of the corporation.

        (c)   The termination of a proceeding by judgment, order, settlement, or conviction, or upon a plea of nolo contendere or its equivalent, is not, of itself, determinative that the director or officer did not meet the relevant standard of conduct described in this Section.

        (d)   Unless ordered by a court, the corporation may not indemnify a director or officer under this Section if his or her conduct did not satisfy the standards set forth in subsection (a) or subsection (b).

        Section 3.    Advance for Expenses.    The corporation shall, before final disposition of a proceeding, advance funds to pay for or reimburse the reasonable expenses incurred by a Director or officer who is a party to a proceeding because he or she is a director or officer if he or she delivers to the corporation:

        (a)   a written affirmation of his or her good faith belief that he or she has met the relevant standard of conduct described in Section 2 of this Article or that the proceeding involves conduct for which liability has been eliminated under a provision of the Articles of Organization as authorized by Section 2.02(b)(4) of the MBCA or any successor provision to such Section; and

        (b)   his or her written undertaking to repay any funds advanced if he or she is not wholly successful, on the merits or otherwise, in the defense of such proceeding and it is ultimately determined pursuant to Section 4 of this Article or by a court of competent jurisdiction that he or she has not met the relevant standard of conduct described in Section 2 of this Article. Such undertaking must be an unlimited general obligation of the Director or officer but need not be secured and shall be accepted without reference to the financial ability of the Director or officer to make repayment.

        Section 4.    Determination of Indemnification.    The determination of whether a Director has met the relevant standard of conduct set forth in Section 2 shall be made:

        (a)   if there are two or more disinterested directors, by the Board of Directors by a majority vote of all the disinterested directors, a majority of whom shall for such purpose constitute a quorum, or by a majority of the members of a committee of two or more disinterested directors appointed by vote;

        (b)   by special legal counsel (1) selected in the manner prescribed in clause (a); or (2) if there are fewer than two disinterested directors, selected by the Board of Directors, in which selection directors who do not qualify as disinterested directors may participate; or

        (c)   by the shareholders, but shares owned by or voted under the control of a director who at the time does not qualify as a disinterested director may not be voted on the determination.

A-10

        Section 5.    Notification and Defense of Claim; Settlements.    

        (a)   In addition to and without limiting the foregoing provisions of this Article and except to the extent otherwise required by law, it shall be a condition of the corporation's obligation to indemnify under Section 2 of this Article (in addition to any other condition provide in these Bylaws or by law) that the person asserting, or proposing to assert, the right to be indemnified, must notify the Corporation in writing as soon as practicable of any action, suit, proceeding or investigation involving such person for which indemnity will or could be sought, but the failure to so notify shall not affect the corporation's objection to indemnify except to the extent the corporation is adversely affected thereby. With respect to any proceeding of which the corporation is so notified, the corporation will be entitled to participate therein at its own expense and/or to assume the defense thereof at its own expense, with legal counsel reasonably acceptable to such person. After notice from the corporation to such person of its election so to assume such defense, the corporation shall not be liable to such person for any legal or other expenses subsequently incurred by such person in connection with such action, suit, proceeding or investigation other than as provided below in this subsection (a). Such person shall have the right to employ his or her own counsel in connection with such action, suit, proceeding or investigation, but the fees and expenses of such counsel incurred after notice from the corporation of its assumption of the defense thereof shall be at the expense of such person unless (1) the employment of counsel by such person has been authorized by the corporation, (2) counsel to such person shall have reasonably concluded that there may be a conflict of interest or position on any significant issue between the corporation and such person in the conduct of the defense of such action, suit, proceeding or investigation or (3) the corporation shall not in fact have employed counsel to assume the defense of such action, suit, proceeding or investigation, in each of which cases the fees and expenses of counsel for such person shall be at the expense of the corporation, except as otherwise expressly provided by this Article. The corporation shall not be entitled, without the consent of such person, to assume the defense of any claim brought by or in the right of the corporation or as to which counsel for such person shall have reasonably made the conclusion provided for in clause (2) above.

        (b)   The corporation shall not be required to indemnify such person under this Article for any amounts paid in settlement of any proceeding unless authorized in the same manner as the determination that indemnification is permissible under Section 4 of this Article, except that if there are fewer than two disinterested directors, authorization of indemnification shall be made by the Board of Directors, in which authorization directors who do not qualify as disinterested directors may participate. The corporation shall not settle any action, suit, proceeding or investigation in any manner which would impose any penalty or limitation on such person without such person's written consent. Neither the corporation nor such person will unreasonably withhold their consent to any proposed settlement.

        Section 6.    Insurance.    The corporation may purchase and maintain insurance on behalf of an individual who is a director or officer of the corporation, or who, while a director or officer of the corporation, serves at the corporation's request as a director, officer, partner, trustee, employee, or agent of another domestic or foreign corporation, partnership, joint venture, trust, employee benefit plan, or other entity, against liability asserted against or incurred by him or her in that capacity or arising from his or her status as a Director or officer, whether or not the corporation would have power to indemnify or advance expenses to him or her against the same liability under this Article.

        Section 7.    Application of this Article.    

        (a)   The corporation shall not be obligated to indemnify or advance expenses to a director or officer of a predecessor of the corporation, pertaining to conduct with respect to the predecessor, unless otherwise specifically provided.

        (b)   This Article shall not limit the corporation's power to (1) pay or reimburse expenses incurred by a director or an officer in connection with his or her appearance as a witness in a proceeding at a

A-11

---

time when he or she is not a party or (2) indemnify, advance expenses to or provide or maintain insurance on behalf of an employee or agent.

        (c)   The indemnification and advancement of expenses provided by, or granted pursuant to, this Article shall not be considered exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled.

        (d)   Each person who is or becomes a director or officer shall be deemed to have served or to have continued to serve in such capacity in reliance upon the indemnity provided for in this Article. All rights to indemnification under this Article shall be deemed to be provided by a contract between the corporation and the person who serves as a Director or officer of the corporation at any time while these Bylaws and the relevant provisions of the MBCA are in effect. Any repeal or modification thereof shall not affect any rights or obligations then existing.

        (e)   If the laws of the Commonwealth of Massachusetts are hereafter amended from time to time to increase the scope of permitted indemnification, indemnification hereunder shall be provided to the fullest extent permitted or required by any such amendment.
