Common Stock, Par Value $5.00 (the "Shares") to be offered for purchase under the Shareholder Investment Plan Yankee Energy System, Inc. ("Yankee Energy" or the "Company") hereby offers participation in its Shareholder Investment Plan (the "Plan"). The Plan is designed to provide investors with a variety of services related to their investment in Yankee Energy. Under the Plan eligible investors may: - - - - Automatically reinvest cash dividends on Shares registered in their name (Dividend Reinvestment Option). - - - - Invest in additional Shares by making voluntary cash payments at any time up to a maximum of $10,000 per month. In addition, members of a registered shareholder's family are eligible to make initial investments in the Company (Voluntary Cash Investment Option). - - - - Sell Shares held in the Plan for a nominal fee (holders of fewer than 100 shares can sell all their Shares with no fee) (Share Sale Option). - - - - Donate Shares to a charitable organization selected by the shareholder (Charity Donation Option). - - - - Deposit Share certificates for safekeeping at no charge (Share Safekeeping Option). Shares may be purchased pursuant to the Plan in the open market, in privately negotiated transactions or from the Company from authorized but previously unissued Shares. At present, it is expected that Shares will be purchased from the Company. The price of any Shares purchased from the Company will be the average of the high and low sales prices of the Shares as reported on the New York Stock Exchange Composite Tape on the relevant Investment Date (as defined in the Plan). In the event Shares are purchased in the open market or by negotiated transactions, the purchase price will be the weighted average price paid by the Plan Administrator (as defined in the Plan) for all such Shares purchased with respect to a particular Investment Date. The closing price of the Shares on October 31, 1994, as shown on the New York Stock Exchange Composite Tape, was $22.375 per share. Shares will be credited to participant accounts at the average price per share of all Shares purchased with respect to the relevant Investment Date. See "Shareholder Investment Plan - Purchases of Shares." Participants pay a nominal $1.50 service charge but no brokerage commissions on each purchase of Shares under the Plan. Shares sold pursuant to the Plan will be sold in the open market and will not be offset against purchases made pursuant to the Plan. 1 This Prospectus relates to 1,200,000 Shares to be offered for purchase under the Plan. To the extent required by applicable law in certain jurisdictions, Shares offered under the Plan to persons not presently shareholders of Yankee Energy are offered through InvestNet Corporation.

Yankee Energy was incorporated in the State of Connecticut in 1989 and operates primarily as a holding company. Yankee Energy's principal operating subsidiary is Yankee Gas Services Company, a state-regulated utility providing retail distribution of natural gas to residential, commercial and industrial customers in Connecticut. The Company's principal executive offices are located at 599 Research Parkway, Meriden, Connecticut 06450 (telephone number (203) 639-4000). USE OF PROCEEDS At present, it is expected that Shares acquired under the Plan will be purchased directly from Yankee Energy, not in the open market. Yankee Energy intends to use any net proceeds from the sale of such Shares for general corporate purposes. No proceeds will be realized by the Company when purchases of Shares pursuant to the Plan are made in the open market or in privately negotiated transactions. 5 THE SHAREHOLDER INVESTMENT PLAN The following is a complete statement of the Shareholder Investment Plan (the "Plan"). The Plan provides eligible shareholders with a variety of services related to their investment in Shares of Yankee Energy. Yankee Energy hopes its shareholders will find the Plan to be a simple, convenient and cost-effective method of purchasing Shares and reinvesting cash dividends in additional Shares. The Plan is administered by Mellon Securities Trust Company ("Mellon" or the "Plan Administrator"). Participation by shareholders is entirely voluntary. Highlights - - - - If you are already enrolled in the Company's previous Dividend Reinvestment and Voluntary Cash Investment Plan, you will automatically be enrolled for these options in the new Plan. If you are eligible, you may enroll for any or all of the other shareholder services offered under this new Plan. Participation is entirely voluntary. - - - - You will pay no brokerage commission and only a nominal $1.50 service charge in connection with each time you purchase Shares under the Plan. - - - - The Plan provides you with an option for automatic reinvestment of cash dividends on all Shares registered in your name, whether or not such Shares are held by Mellon in a Plan account. In addition, or alternatively, you may purchase additional Shares through voluntary cash investments (subject to a minimum of $100 and a maximum of $10,000 per month). You may make such investments occasionally or at regular intervals, as you wish. - - - - Your family members may buy Shares directly from Yankee Energy, or you may buy Shares in the name of a family member as a gift. In each case, the minimum initial investment is $500, and the maximum investment is $10,000 per month. - - - - If you hold fewer than 100 Shares, you may, at any time, elect to sell all (but not less than all) of your Shares without paying any brokerage or service charge. For any other sale of Shares under the Plan, you will incur a $5.00 administrative fee plus a brokerage commission of $.06 per Share sold. - - - - You may also choose to donate all or a portion of your Shares to a charitable organization of your choice. The charitable organization will then have the benefits of the Plan, including the Share Sale option. - - - - Plan Shares are automatically held by Mellon for safekeeping at no cost to you. For your convenience, you may deposit other Share certificates registered in your name with Mellon to be maintained as part of your Plan account. - - - - Statements will be mailed to you after each purchase or sale in your account. The statements show the dividends and/or voluntary cash investments received, the number of Shares purchased or sold, the price, the service charge, if any, and the total number of Shares held in the your Plan account. 6 Administration The Plan Administrator is not affiliated with the Company. Yankee Energy will not exercise any direct or indirect control or influence over the times when, or the prices at which, the Plan Administrator may purchase or sell Shares, the amount of Shares to be purchased, or the selection of a broker or dealer through which purchases or sales of Shares pursuant to the Plan may be executed. Mellon will be the Plan Administrator and will purchase, sell and hold Shares acquired under the Plan, keep records, send statements of account activity to participating shareholders, and perform other duties related to the Plan. Shareholders should direct any questions or communications about the Plan to: Mellon Securities Trust Company Dividend Reinvestment Services P.O. Box 750 Pittsburgh, Pennsylvania 15230 Shareholders can call Mellon toll fee at 1-800-288-9541 between 9 a.m. and 5 p.m. Eastern time. Eligibility Eligibility for the shareholder services offered under the Plan is shown below. Option Eligibility Dividend All registered shareholders of 50 or Reinvestment more Shares. Voluntary Cash All registered shareholders and their Investment family members. Share Sale All registered shareholders of fewer than 100 Shares may sell all their Shares for no fee, whether or not such Shares are held in a Plan account. All registered shareholders with Plan Shares may sell Plan Shares for a nominal fee. Charity Donation All registered shareholders. Share Safekeeping All registered shareholders. 7 A "family member" is defined as any member of the shareholder's extended family, including but not limited to the following: child, spouse, parent, sibling, grandparent, grandchild, aunt, uncle, cousin, nephew or niece. Enrollment Procedures PARTICIPANTS IN YANKEE ENERGY'S PREVIOUS DIVIDEND REINVESTMENT AND VOLUNTARY CASH INVESTMENT PLAN WILL AUTOMATICALLY BE ENROLLED FOR THESE OPTIONS IN THE NEW PLAN. To enroll, after being furnished with a copy of this Prospectus, you should complete and sign an Enrollment Form, select the option(s) you want to participate in and return it to Mellon. If you are a current registered shareholder, you must sign your name (or names, in the case of joint ownership) on the Enrollment Form exactly as shown on your Share certificates. If your Shares are registered in another name (such as a broker, bank or trustee) and you wish to participate in the Plan (excepting the Odd-Lot Sale feature), you must contact the broker, bank or trustee and request that your Shares be issued in your name in certificate form. This step will make you eligible for the Plan as a registered Yankee Energy shareholder. Family members of a registered shareholder of Yankee Energy Shares must include a personal check or money order payable to Mellon Securities Transfer Services for the minimum initial investment of at least $500 with the completed Enrollment Form. Participation in the Plan will begin after the properly completed Enrollment Form has been reviewed and accepted by Mellon. PURCHASES OF SHARES: DIVIDEND REINVESTMENT OPTION AND VOLUNTARY CASH INVESTMENT OPTION You may elect to have cash dividends paid on all Shares registered in your name, whether or not such Shares are held in a Plan account, reinvested in additional Shares (Dividend Reinvestment Option). To enroll, you should send an Enrollment Form to Mellon, indicating an election for the Dividend Reinvestment Option. Once initiated, dividend reinvestment will occur with respect to all cash dividends earned on Shares registered to you and will continue until you elect to receive cash dividend payments. You also may elect to make voluntary cash investments by personal check or money order payable to Mellon Securities Trust Company, in U.S. dollars (Voluntary Cash Investment Option). Voluntary cash investments must be at least $100 for any single investment ($500 in the case of initial investments by or for a family member who is not already a shareholder) and may not exceed $10,000 per month. Once enrolled, there is no obligation to make voluntary cash investments at any time, and (subject to the applicable minimums) the amount of such investments may vary from time to time. Voluntary cash investments must be mailed to Mellon together with an Enrollment Form. Subsequent cash investments must be mailed to Mellon with the Cash Investment Form which is attached to each statement of account sent to you. Additional Enrollment Forms and Cash Investment Forms are available upon request from Mellon. 8 A service change of $1.50 will be charged to you for each calendar quarter in which you participate in the Dividend Reinvestment option, and for each month in which you make a Voluntary Cash Investment. Yankee Energy will incur the balance of the cost of any purchases of Shares pursuant to the Plan, as well as all brokerage charges for the Shares purchased. The service charge will automatically be deducted from the dividend payment or voluntary cash investment amount and the net amount will be used to purchase Shares. For months where you are participating in both the Dividend Reinvestment and the Voluntary Cash Investment options, a single service charge of $1.50 will be deducted from the total investment amount. Investment Dates Investment Dates will normally be the last business day of each month except for months in which dividends are paid, in which case the Investment Date will be the dividend payment date. Voluntary cash investments must be received by Mellon no later than three business days prior to an Investment Date to be invested with other funds received for that Investment Date. Voluntary cash investments received by Mellon less than three business days prior to an Investment Date will be held by Mellon until the next Investment Date. No interest will be paid on amounts held by Mellon pending investment. All investments of cash deposits are subject to collection of full value in U.S. funds for any check or money order. You may obtain a refund of any cash deposits provided your request for refund is made in writing and is received by the Plan Administrator at least two business days prior to the Investment Date. Refunds will not be made until checks or money orders have cleared. Source and Price of Shares The Company will direct the Plan Administrator to purchase Shares either in the open market, through negotiated transactions or directly from the Company from previously unissued Shares. At present, it is expected that Shares will be purchased from the Company. The Company will not change its determination with respect to the source of Shares purchased for the Plan except in compliance with applicable law, regulations or policies of the Securities Exchange Commission. If the Shares are to be purchased in the open market or in privately negotiated transactions, neither the Company nor you will have the power or authority to direct or influence the times when, or the price at which, Shares may be purchased by the Plan Administrator, the number of Shares to be purchased, the manner of such purchases or the selection of the broker or dealer through which such purchases will be made. 9 Mellon will commingle all dividends and voluntary cash investments that it receives at least three business days prior to the Investment Date for the purpose of executing purchases. Sales made by Mellon under the Share Sale Option of the Plan will not be offset against purchases made by Mellon. Shares purchased from Yankee Energy will be credited to your Plan account at a price per share that is the average of the high and low sales prices of the Shares as reported on the New York Stock Exchange Composite Tape on the Investment Date. If the Shares are not traded on that Investment Date, the purchase price per share will equal the average of the high and low sales prices of the Shares as reported on the New York Stock Exchange Composite Tape on the next business day on which the Shares are traded. Shares purchased on the open market or in negotiated transactions will be credited to your Plan account at the weighted average price per share of all Shares purchased by the Plan Administrator, as applicable, with respect to the Investment Date. Shares will be purchased at times determined in Mellon's best judgment as funds for a given Investment Date become available. The number of Shares purchased for you depends on the amount of your reinvested dividends and/or voluntary cash investments, less the $1.50 service charge, divided by the applicable purchase price per share on the Investment Date. Your Plan account will be credited with this number of Shares, including fractional Shares computed to four decimal places. Shares purchased under the Plan will be held by Mellon for you under the Share Safekeeping option of the Plan. SHARE SALE OPTION You may sell Shares under certain conditions under the Plan (Share Sale Option), as follows. Odd-Lot Sales If you hold fewer than 100 Shares, whether or not such Shares are held in a Plan account, you may sell all (but not less than all) of such Shares at any time and pay no brokerage fees or commissions. To sell all your Shares, you must send any Share certificates to Mellon (by registered, insured mail), along with a completed Enrollment Form. If you cannot locate the required Share certificates, you should call Mellon for the appropriate forms. 10 Cash Withdrawals from the Plan You may instruct Mellon to sell any number of whole Shares held in your Plan account in order to make a partial cash withdrawal. Only one partial cash withdrawal may be requested in each calendar year. A partial withdrawal does not affect your right to elect a complete withdrawal from the Plan at any time. Alternatively, you may elect a complete cash withdrawal by requesting that all whole Shares in your Plan account be sold as of the next Investment Date. A complete cash withdrawal automatically terminates participation in the Plan. You will be charged a $5.00 administrative charge to process a partial or complete cash withdrawal, as well as a brokerage commission of $0.06 per share for any Shares sold. All sales under the Share Sale Option will be commingled, and the Plan Administrator will make the sale as of an Investment Date at times determined in its best judgment. All sales orders received in good order at least three business days before the Investment Date will be included in the sale for that Investment Date. Sales will be credited to your Plan account at the weighted average price per share of all Shares sold by the Plan Administrator with respect to an Investment Date. Checks for proceeds will be mailed to you, net of the administrative and brokerage charges, if any, within two weeks following the Investment Date. If you are enrolled in the Dividend Reinvestment option of the Plan and you submit a share sale request for all of your Plan Shares after a dividend record date but before the related dividend payment date, there will be a delay in processing your request. This request will not be processed until the Investment Date next succeeding the dividend payment date to ensure the total liquidation of your Plan Shares. You will not have the authority or power to direct the date or price at which your Shares may be sold or the manner of such sale. Any Share Sale election must indicate the number of Shares to be sold and not the dollar amount to be attained. CHARITY DONATION OPTION Yankee Energy encourages support of charitable organizations. Stock gifts can be an important component of a charitable organization's fund-raising program, and there may be tax advantages to the shareholder for gifts of stock that have appreciated in value since acquisition by the shareholder. You may elect to donate all or a portion of your Shares to a charitable organization of your choice (Charity Donation Option), whether or not such Shares are held in a Plan account. To transfer your Shares, mail to Mellon a properly completed Enrollment Form and the Share certificates if not held in a Plan account. If you cannot locate the required Share certificates, you should call Mellon for the appropriate forms. The charitable institution will then be eligible to enroll in the Plan and will be entitled to all of the benefits of the Plan, including the Share Sale Option. Yankee Energy will mail to you an acknowledgment of the market value of the donated Shares on the date of transfer for your tax records. 11 SHARE SAFEKEEPING OPTION Plan Shares are automatically held by Mellon for safekeeping at no charge. You may also send other Share certificates held by you as the registered owner to Mellon for safekeeping at no charge. All Plan Shares will be credited to a Plan account for you, and will be maintained in the name in which the Shares are registered at the time you enroll in the Plan. Thereafter, Shares deposited for safekeeping will be treated in the same manner as Shares purchased through the Plan and may be transferred, sold or withdrawn through the Plan in the manner described in this Prospectus. To deposit Share certificates with Mellon, you must complete and return to Mellon, by registered, insured mail, the Share certificates to be deposited along with an Enrollment Form available from Mellon. The Share certificates should not be endorsed. OTHER INFORMATION Gift/Transfer of Shares Within the Program You may transfer the ownership of all or any whole number of Shares held under the Plan to a Plan account for another person, whether by gift, private sale or otherwise, by mailing to Mellon a properly completed Share Transfer form, along with an executed Stock Power, with signature guaranteed by an eligible guarantor institution. Such institutions generally include banks, brokers, dealers, credit unions, savings associations and other entities which are members in good standing of the Securities Transfer Agent's Medallion Program. Fractional Shares will be transferred only if you choose to transfer your entire Plan account. The transferee will automatically be enrolled under the Share Safekeeping option of the Plan and will receive a statement showing the number of Shares transferred to and held in the transferee's Plan account. Share Transfer forms and Stock Power forms are available upon request from Mellon. Reports to Participants You will receive a statement after any purchase of Shares for your Plan account showing the amount invested, the purchase price, the number of Shares purchased, deposited, sold, transferred or withdrawn, the total number of Shares accumulated, any service or brokerage charges and other information. The statement will consolidate all Shares registered in your name, whether or not such Shares are held in your Plan account. You should retain these statements in order to establish the cost basis of Shares purchased under the Plan for income tax and other purposes. Duplicate statements will be available from Mellon. 12 All notices, statements and reports from Mellon will be addressed to your latest address of record. PROMPTLY NOTIFY MELLON OF ANY CHANGE IN YOUR ADDRESS. Proxies If proxy materials are to be sent to you in connection with any annual or special meeting of shareholders, you will receive a single proxy card covering those Shares credited to your Plan account and any other Shares registered in your name that are not Plan Shares. If the proxy card is returned properly signed and marked for voting, all of the Shares will be voted as marked. Stock Split, Stock Dividends or Rights Should Yankee Energy declare a stock split or pay any dividends in Shares, all Plan Shares will be eligible. Dividend or split Shares distributed by the Company on Shares held by Mellon for Plan accounts will be added to the Plan accounts. Dividend or split Shares distributed on all Shares not held in a Plan account will be mailed directly to you in the same manner as to shareholders who are not participating in the Plan. Should Yankee Energy make available to holders of Shares any rights to purchase or receive securities other than Shares, the Plan Administrator will sell such rights accruing to Plan Shares and invest the resulting funds in Shares, which will be credited to your Plan account. If you wish to exercise such rights, you should request that the Plan Administrator issue Share certificates to you so the rights to purchase or receive additional Shares will accrue to those certificates. Withdrawal of Shares Share certificates may be obtained for all or some of the whole Shares held in a Plan account by giving written instructions to Mellon. Withdrawal of Shares in the form of a Share certificate in no way affects your dividend reinvestment election. Upon full withdrawal of shares from the Plan, you will receive a Share certificate for the whole Shares held in their Plan account, together with a check for the cash value (as of the next Investment Date after receipt of the withdrawal notice) of any fractional Shares held in the account. Certificates for fractional Shares will not be issued under any circumstances. 13 Change or Termination of the Plan The Company reserves the right to suspend, modify or terminate the Plan at any time in whole, in part, or in respect of shareholders in one or more jurisdictions, without prior notice. Company and Plan Administrator Responsibilities Neither the Company nor the Plan Administrator (nor any of their respective agents, representatives, employees, officers, directors or subcontractors) will be liable in administering the Plan for any act done in good faith nor for any good faith omission to act, including, without limitation, any claim of liability arising out of failure to terminate a participant's account upon death or with respect to the prices at which Shares are purchased or sold for Plan accounts, the times when purchases or sales are made, or with respect to any fluctuation in market value of the Shares. You must recognize that the Company cannot assure a profit or protect against a loss on the Shares purchased or sold under the Plan, and that the Company cannot assure that it will continue to pay dividends on the Shares in the future. In the event that applicable law or the closing of securities markets requires the temporary curtailment or suspension of purchases or sales of Shares under the Plan, Mellon shall not be accountable for its inability to make purchases or sales at such times. If such curtailment or suspension continues for a period longer than 90 days, Mellon will promptly mail to you a check in the amount of any unapplied funds in your Plan account. TAX CONSEQUENCES OF PARTICIPATION Yankee Energy believes the following is an accurate summary of the federal income tax consequences of participation in the Plan as of the date of this Prospectus. This summary may not reflect every possible situation that could result from your participation in the Plan, and may be affected by future legislation, IRS rulings and regulations or court decisions. In addition, the rules discussed below may not be applicable to certain participants in the Plan, such as tax exempt entities (e.g., pension funds and IRAs). You are advised to consult your tax or financial advisor with respect to federal, state, local and other tax laws that apply to your participation in the Plan and the subsequent disposal of any Shares you purchase pursuant to the Plan. 14 Cash dividends paid to individuals, including those generated by Shares held in the Plan, generally are subject to taxation in the year paid. For federal income tax purposes, there is no distinction between a dividend paid in cash and a dividend reinvested according to your instructions. Shares purchased with voluntary cash investments will not cause you to realize taxable income at the time of the purchase. In either case, the brokerage commissions and fees paid by Yankee Energy on your behalf, if any, are treated as income for U.S. income tax purposes. The price for Shares purchased under the Plan, shown in each December transaction statement, plus brokerage commissions and fees, shown on the Form 1099-DIV sent at year end, together are considered the cost basis for any Shares purchased. You should retain this information, which will be needed by you when the Shares are sold. In the case of foreign shareholders whose dividends are subject to U.S. withholding tax or other participants whose dividends are subject to backup withholding, the amount of tax to be withheld will be deducted from the amount of dividends and only the reduced amount will be reinvested by Mellon in Shares. You are responsible for filing any documentation required to obtain any reduction in the required withholding tax. The sale of Shares under the Plan is a taxable transaction for federal tax purposes and may also be taxable under state and local laws. You may realize a taxable gain or loss on the sale of Shares under the Plan and, in the case of a fractional Share, when you receive a cash payment for a fraction of a Share held in your Plan account upon termination of your participation in or the termination of the Plan. The amount of such gain or loss will be the difference between the amount that you receive for the Shares or fractional Share and the tax basis thereof. There is no recognizable event for federal income tax purposes if you request that certificates representing your Plan Shares be issued to you, whether pursuant to "Withdrawal of Shares" hereunder or upon your withdrawal from participation in or termination of the Plan. In the case of Shares held by an individual as a long-term capital asset that are donated to a charitable organization, if you itemize deductions, in most cases you will be able to claim a tax deduction for the market value of the contributions, subject to certain limitations based on such matters as the amount of your adjusted gross income and whether the designated charitable organization is a private foundation. Yankee Energy will mail to you an acknowledgment of the market value of the Shares donated under the Charity Donation Option. In addition, the Company will work with the charitable organization to provide you with the requisite information to satisfy IRS substantiation rules. 15 LEGAL OPINIONS Legal matters concerning the Plan and the legality of the Shares offered hereby have been passed upon for the Company by Shipman & Goodwin, Hartford, Connecticut counsel for the Company.

INDEMNIFICATION Section 33-320a of the Stock Corporation Act of Connecticut ("Section 33-320a") requires the Company, in certain circumstances and subject to certain limitations therein set forth, to indemnify each of its directors and officers, among others, made a party to any threatened, pending or completed legal proceeding by reason of his or her being or having been such a director or officer, against expenses, including attorneys' fees, incurred by him or her, and, in addition in the case of any such proceeding other than one by or in the right of the Company, against judgments, fines and penalties incurred, and settlement amounts paid, by him or her in connection with such proceeding. Article VI of the Bylaws of the Company provides for indemnification of directors and officers, among others, to the fullest extent now or hereafter permitted by law. The rights and remedies provided in Section 33-320a are exclusive, so Article VI of the Bylaws of the Company does not at present add to the indemnification rights of directors and officers. Section 33- 320a authorizes the Company to procure insurance providing greater indemnification than that authorized by Section 33-320a. The Company has purchased insurance policies which insure directors and officers of the Company and of certain of its subsidiaries against certain liabilities which might be incurred by them in such capacities and which insure the Company for amounts which may be paid by it to indemnify the directors and officers covered by the policies. 16 Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling the Company pursuant to the foregoing provisions, the Company has been informed that, in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. 17 SHAREHOLDER INVESTMENT PLAN PROSPECTUS _________, 1994 TABLE OF CONTENTS Page Available Information 3 Incorporation of Documents by Reference 4 Yankee Energy System, Inc. 4 Use of Proceeds 5 Shareholder Investment Plan 6 Highlights 6 Administration 7 Eligibility 7 Enrollment Procedures 8 Purchases of Shares: Dividend Reinvestment Option 8 and Voluntary Cash Investment Option Investment Dates 9 Source and Price of Shares 9 Share Sale Option 10 Charity Donation Option 11 Share Safekeeping Option 12 Other Information 12 Gift/Transfer of Shares Within the Program 12 Reports to Participants 12 Proxies 13 Stock Split, Stock Dividends or Rights 13 Withdrawal of Shares 13 Change or Termination of the Plan 14 Tax Consequences of Participation 14 Legal Opinions 16 Experts 16 No dealer, salesperson or other person has been authorized to give any information or to make any representations other than those contained or incorporated by reference in this Prospectus and, if given or made, such information or representations must not be relied upon as having been authorized by Yankee Energy or any dealer or agent.

II-1 Section 33-320a authorizes the Company to procure insurance providing greater indemnification than that authorized by Section 33-320a.

Undertakings The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post- effective amendment any of the securities being registered which remain unsold at the termination of the offering. The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the Registration Statement shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. The undersigned Registrant hereby undertakes to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report, to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934; and, where interim financial information required to be presented by Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information. Insofar as indemnification of liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or II-3 paid by a director, officer or controlling persons of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. II-4 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Meriden and State of Connecticut on the 4rd day of November, 1994.
