When calculating the number or percentage of Shares owned by a Shareholder, all Shares of convertible preferred stock 2 shall be deemed to be converted to Shares of Common Stock at the then conversion ratio and such Shareholder shall be deemed to own all Shares of Common Stock issuable upon the conversion of preferred stock of the Corporation. Aside from the signatories of this Agreement, except as provided herein, no person shall have the right to sign this Agreement and no person shall be entitled to the benefits of this Agreement. Capitalized terms used but not defined in this Agreement shall have the same meaning as in the Purchase Agreement of even date among the parties hereto (other than Prudential) ("Purchase Agreement"). 1.3 The Shareholders desire to impose certain restrictions on the sale, transfer or other disposition of the Shares and to make arrangements for the voting of the Shares. 1.4 The Shareholders have agreed that for the purpose of designating candidates for election of directors the Shareholders shall be divided into four categories of shareholders, as follows: Name Category ---- -------- Petroleum Heat and Power Co., Inc.

Elections to the Board of Directors. ----------------------------------- 2.1 Star Gas shall be governed by a Board of Directors consisting of no less than 6 and no more than 8 persons. Each category of Shareholder shall have the right to nominate directors as follows: The Petro Shareholder shall have the right to nominate for election up to but no more than 3 directors, the Holdings Shareholder shall have the right to nominate for election up to but no more than 2 directors, the First Reserve Shareholders shall have the right to nominate for election up to but no more than 1 director so long as the First Reserve Shareholders collectively hold at least 5% of the outstanding Shares and the Prudential Shareholder shall have the right to nominate for election no more than 2 directors so long as the Prudential Shareholder holds at least 15% of the outstanding Shares and the right to nominate for election 1 director so long as the Prudential Shareholder holds at least 5% and less than 15% of the outstanding Shares. The outstanding Shares for purposes of calculating the percentage of any category of Shareholders shall exclude Shares resulting from additional 4 issuances of equity securities after the date hereof other than (i) pursuant to the conversion of Convertible Preferred Stock outstanding on the date hereof and (ii) Shares issued in accordance with Section 4 hereof to the extent that such category of Shareholders have exercised their preemptive rights. 2.2 (a) The current Board of Directors shall consist of the following persons: Petro Shareholder First Reserve Prudential Directors Shareholders Director Shareholder Directors --------- --------------------- --------------------- 3 persons 1 person 2 persons Holdings Shareholder Directors --------- 2 persons (b) The Shareholders agree to vote their Shares at any meeting of the Shareholders of Star Gas called for such purpose (or to deliver their written consents in lieu of such a meeting) as follows: (i) To fill any vacancy on the Board of Directors by the election of a person designated by the Shareholders of the category of Shareholders entitled to fill such vacancy. (ii) To remove from office any director elected as a representative of the Petro Shareholder, the Holdings Shareholder, the First Reserve Shareholders or the Prudential Shareholder at the request of the Shareholders of the category of Shareholders which initially designated the director. 5 The Petro Shareholder, the Holdings Shareholder, the First Reserve Shareholders or Prudential Shareholder may make their request for the election or removal of a director representing the Shareholders of their respective category by delivering to the other Shareholders one or more written instruments signed by the holders of the Shares representing a majority of the voting power of the Shares held by the category of Shareholders making the request. The right to designate nominees for directors and to have them elected under this Article shall inure to the benefit of transferees of Shares pursuant to Articles 5 and 6; provided, however, that such benefits shall not inure to a person which purchases Shares from Prudential pursuant to Section 5.2 prior to the date of a Change of Control with respect to Petro. 2.3 For as long as the First Reserve Shareholders are entitled to designate a director to the Board of Directors, each First Reserve Shareholder that is a First Reserve Shareholder on the date hereof (a "Current FRC Shareholder") shall be entitled to designate a non-voting observer to attend meetings of the Board of Directors, provided that the aggregate number of observers and the First Reserve Shareholder director shall not exceed the number of Current FRC Shareholders. The Corporation shall provide each such observer with the same notice of meetings of the Board of Directors as that provided to 6 directors. Each such observer shall be provided reasonable access to the books, records and properties of the Corporation and shall be provided with a reasonable opportunity to discuss the business and affairs of the Corporation with the officers of the Corporation, provided that the First Reserve Shareholders shall cause all information relating to the Corporation that is provided to such observers to be held in confidence. 3. Certain Action Requiring Super Majority -------------------------------------------------- Shareholder Vote. ---------------- 3.1 The Shareholders shall vote their Shares to include in the Certificate of Incorporation of Star Gas provisions that whenever Star Gas shall take any of the actions specified below, such action may be taken only by the affirmative vote of the holders of eighty percent (80%) (this percentage shall be adjusted after the issuance of any Shares after the date hereof or upon the sale by Prudential of any Shares as provided in Section 3.2) of the Shares (for this purpose, Shares includes the Series B and Series D 8% Cumulative Convertible Preferred Stock); provided, however, that (i) so long as Prudential shall own 10% or more of such Shares no such action shall be taken without the affirmative vote of Prudential; (ii) so long as First Reserve Shareholders own any Common Stock no change will be made to the Certificate of Designation of Star Gas establishing the relative rights and preferences of the 8% Cumulative Convertible Preferred Stock and the 12.625% Cumulative Redeemable Preferred Stock without the affirmative vote of the First Reserve 7 Shareholders holding a majority of the Common Stock owned by such category; and (iii) the affirmative vote of a majority of the holders of Shares of each Shareholder category shall be required to approve any merger or other business combination in which the value of the consideration (as determined pursuant to Section 5.7) to be received by any class or series of stock is not equal to that received by all others: (a) Any material change in the Certificate of Incorporation or any Certificate of Designations establishing the relative rights and preferences of any class of preferred stock. (b) The merger or consolidation of the Corporation with any other Corporation if such other Corporation is engaged in any business other than the sale and distribution of propane and other activities which are incidental to such business, except the merger of any subsidiary into another subsidiary or the Corporation. (c) The liquidation or dissolution of the Corporation. (d) Engaging in any business other than the (i) sale and distribution of propane and other activities which are incidental to 8 that business and (ii) the engagement by Star Gas' Highway division in its present business activities. (e) Granting to any employee of Star Gas any option, warrant or right to purchase any shares of capital stock of Star Gas. (f) Except pursuant to the Star Gas Put/Call Agreement of even date between the Corporation and Prudential, repurchasing from any Shareholder any shares of capital stock of Star Gas except as contemplated by the express terms of such capital stock. (g) Modifying, amending, repealing or adopting any By-Law of Star Gas that would materially alter the rights of any category of Shareholders. (h) Any reorganization or recapitalization of the Corporation or the reclassification of the Corporation's capital stock. (i) Amending, modifying or renewing the Management Services Agreement. (j) The sale by the Corporation of any securities to a Shareholder or any affiliate of a Shareholder other than 9 for cash or other than pursuant to the Petro Option, the FRC Option and the Management Services Agreement. 3.2 If solely as a result of the sale or issuance of additional equity securities of the Corporation, Prudential shall own shares representing less than twenty percent (20%) of the voting power of all shares entitled to vote on the matters listed above, then the eighty percent (80%) voting requirement shall be changed to equal that percentage that is one percentage greater than 100% minus the actual percentage voting power of Prudential; provided, however, (i) the percentage voting requirement shall never exceed ninety percent (90%) and (ii) upon transfer of Shares by Prudential pursuant to Article 5.2, the voting percentage shall be reduced to sixty-six and 2/3 percent (66 2/3%) if at the time of such transfer or any time thereafter the FRC Shareholders hold less than 20% of the voting power of all Shares entitled to vote on such matters. Notwithstanding the foregoing, Sections 3.1 and 3.2 shall terminate at such time that (a) Prudential holds less than 10% of the voting power of all Shares entitled to vote on such matters and (b) the FRC Shareholders hold less than 20% of the voting power of all Shares entitled to vote on such matters. It is understood that any sale of the assets or stock of Petroleum Heat and Power Co., Inc. ("Petro") or a merger or consolidation to which Petro is a party, other than a sale to, or 10 a merger or consolidation with, Star Gas, is not covered by this Section. 3.3 The By-Laws of the Corporation shall provide that a special meeting of Shareholders shall be called by the Secretary at the request of the holders of a majority of the Shares held by any category of Shareholders or as otherwise required by law. 3.4 Approval of Certain Matters. The affirmative --------------------------- vote of a majority of the disinterested members of the Corporation's Board of Directors, including, so long as there are any Prudential Shareholder directors, at least one Prudential Shareholder director and one First Reserve Shareholder director, shall be required for each of the following: (a) (i) Entering into or modifying any agreement, arrangement or contract (other than an agreement or contract for the issuance or sale of equity securities governed by Article 4 hereof) between Star Gas and any Shareholder or any entity or person controlling, controlled by or under common control with, any Shareholder, or (ii) issuing or selling any securities to any Shareholder or any entity or person controlling, controlled by or under common control with, any Shareholder (other than any issuance or sale of equity securities 11 governed by Article 4 hereof or any issuance of equity securities upon the conversion or exchange of other securities in accordance with their terms). (b) Approving the reimbursement of Petro for services rendered pursuant to Paragraph 4(d) of that certain Management Services Agreement dated the date hereof between Petro and Star Gas. (c) The exercise by the Corporation of First Refusal Rights pursuant to this Agreement. For purposes of this agreement, a "disinterested director" is a director of the Corporation that does not have any direct or indirect interest in the relevant matter and who was appointed by a shareholder group no member of which, nor any affiliate of any such member, has any direct or indirect interest in the relevant matter except, in any such case, as a stockholder of Star Gas, provided that the Holdings Shareholder Directors and the Petro Shareholder Directors shall be deemed to be independent of each other and disinterested as to matters only affecting the other, unless Holdings owns securities representing 5% or more (i) of the voting power of Petro's voting securities or (ii) in value of Petro's outstanding equity securities. For purposes of paragraph (a) above, each member of the Sevin Group shall be deemed to control Petro. 12 Notwithstanding the foregoing, at such time as there are no Prudential Shareholder directors serving the affirmative vote of the First Reserve Shareholders director shall be required to take any action with respect to the matters set forth in subsections (a), (b) or (c) of this Section 3.4. 3.5 The restrictions contained in this Article 3 that are applicable to Star Gas shall also apply to each Company Subsidiary (as defined in the certain Purchase Agreement) now existing or hereafter created and any restricted activity shall not be taken without the required Star Gas director approval. 3.6 In the event the Corporation sells all or substantially all of its assets, then at the election of Prudential, all of the Shareholders shall vote their Shares so as to cause the dissolution and liquidation of the Corporation. 3.7 The provisions of this Article 3 shall terminate immediately upon the completion of the initial public offering of the Common Stock of the Corporation. 3.8 All propane distribution business opportunities that are referred to Petro shall be deemed business opportunities of the Corporation and not of Petro. Petro may not avail itself of any such opportunity without the unanimous vote of the disinterested directors of the Corporation. 4. Sale of Equity Securities. ------------------------- 4.1 If the Board of Directors shall determine that it is in the best interest of the Corporation to sell equity securities for cash, then the Corporation may sell such equity 13 securities provided, however, that prior to such sale the Corporation shall provide to the Shareholders for a period of 30 days and on a pro rata basis in proportion to the number of Shares owned by each Shareholder the right to purchase such equity securities on the same terms and conditions as the Corporation proposes to sell them. Each Shareholder may elect to purchase all or any part of its pro rata portion of such securities and may transfer its pre-emptive rights to one or more persons controlling, controlled by or under common control with such Shareholder. In determining the number of Shares of Common Stock owned by a Shareholder for purposes of this Section, each Shareholder shall be deemed to own the number of shares of Common Stock actually owned by it plus the number of shares of Common Stock issuable to it upon the conversion of the 8% Cumulative Convertible Preferred Stock of the Company owned by such Shareholder. Any Shareholder may condition its election to purchase such equity securities on any one or more Shareholders also electing to purchase such equity securities. Subject to the preceding sentence, to the extent that all or any portion of such equity securities are not purchased and paid for by the Shareholders within such 30 day period, the Corporation may sell such unpurchased securities on substantially the same terms and conditions for a period of 120 days following the expiration of such 30 day period. To the extent that such equity securities are not sold during such period of 120 days, this section shall apply to any future sale. The provisions of this Section 4.1 14 shall terminate immediately upon the completion of the initial public offering of Common Stock of the Corporation. 4.2 The Shareholders agree to cause the Corporation to change its capital structure immediately prior to any initial offering of equity securities of the Corporation to the public. The new capital structure shall require that each Shareholder contribute ten percent (10%) of the Shares that it holds at such time to the Corporation in return for an equal number of shares of Class C Common Stock having the terms contained in the Amended and Restated Certificate of Incorporation of Star Gas in effect on the date hereof. In such event, the provisions of this Agreement that relate to the Shares will terminate with respect to the Shares and will instead apply to the shares of such Class C Common Stock. Notwithstanding the foregoing, holders of Class B Common Stock (non-voting) may elect in writing not to exchange their Shares for Class C Common Stock. Such election shall be irrevocable. 5. No Shares of the Corporation shall be sold, trans- ferred, hypothecated, negotiated, pledged, assigned, encumbered or otherwise disposed of by any Shareholder, except as herein provided in accordance with the following procedures and the procedures set forth in Article 6: 5.1 Any Shareholder may transfer all or any por- tion of his Shares to any other Shareholder in its category of 15 Shareholders, and Holdings may transfer its shares to Petro, free of the First Offer Right and First Refusal Right referred to below. Following any Change of Control with respect to Petro, Prudential and each of the FRC Shareholders may transfer its Shares free of any restrictions imposed by this Agreement. A Shareholder may transfer Shares to any other person or entity controlling, controlled by or under common control with it, free of the First Refusal Right, and Prudential may transfer Shares to any portfolio or fund managed or advised by Prudential or any of its affiliates without restriction. In addition, the First Reserve Shareholders may pledge their Shares to Brooklyn Union Gas or a wholly owned subsidiary thereof or transfer the pledged Shares subject to Section 5.4 hereof. 5.2 In addition to any rights it may have under Section 5.3 below, Prudential may sell Shares to a Qualified Purchaser provided it has granted a right to purchase such Shares ("First Offer Right") first to the Corporation and then to Petro and Holdings as follows: (a) Prudential shall give notice to the Corporation and to Petro and Holdings stating its intention of offer for sale a number of Shares, the number of Shares intended to be so offered, the price at which such Shares will be offered and any other terms of the Offer. (b) Petro and Holdings shall have the First Offer Right for a period of 30 days to purchase all, but not less than all, of the Shares described in the notice and on a pro rata 16 basis (or on such other proportions as they may agree upon) on the same terms and conditions and at the same price. (c) If the First Offer Right is not exercised in its entirety as provided above, then no Shares shall be purchased pursuant to this Section 5.2 and Prudential, subject to the conditions set forth in Article 6, may sell such Shares to a Qualified Purchaser (and to no other purchaser) in accordance with the terms and at a price not less than the price specified in the notice during the period of 120 days following the expiration of the First Offer Right. (d) If such Shares are not sold as provided herein within such period of 120 days, this Article 5 shall apply to any future offer. 5.3 No Shareholder (other than sales by Prudential pursuant to Section 5.2) ("Offeror Shareholder") may sell any Shares until it has granted a right to purchase its shares ("First Refusal Right") first to the Corporation and then to the other Shareholders, including Prudential, as follows: (a) If an Offeror Shareholder receives from a third party or third parties (other than an underwriter in connection with any public offering of Shares) a bonafide offer or offers ("First Refusal Offer") to purchase or otherwise acquire all or a portion of its Shares, it shall provide written notice ("First Refusal Notice") to the Corporation and the other Shareholders of the terms of the First Refusal Offer which shall identify the purchaser(s), the number of Shares subject to the 17 First Refusal Offer, the price and all other terms and conditions. If the First Refusal Offer consists in part or in whole of consideration other than cash, the Offeror Shareholder shall provide such information as may be reasonably necessary to analyze the non-cash component of the consideration, together with the Offeror Shareholder's estimate of the fair value of such non-cash component. (b) Subject to subsection 5.3(d), for a period of 15 days from the receipt of such notice, the Corporation shall have the First Refusal Right to purchase all or any portion of the Shares described in the First Refusal Notice on the same terms and conditions and at the same price specified in the First Refusal Notice. (c) Subject to subsection 5.3(d), if the First Refusal Right is not exercised in its entirety by the Corporation, then the other Shareholders shall have the First Refusal Right for an additional period of 15 days to purchase the remaining Shares described in the First Refusal Notice on a pro rata basis (or in such other proportions as they may agree upon) on the same terms and conditions and at the same price as described in the First Refusal Notice. (d) If the First Refusal Right is not exercised in its entirety as to all of the Shares as described above, then no Shares shall be purchased pursuant to this Section 5.3 and the Offeror Shareholder may sell such Shares in accordance with the First Refusal Offer during the period of 120 18 days following the expiration of the First Refusal Right and to the extent such Shares are not sold as provided herein within such period of 120 days, this Article 5 shall apply to any future offer. 5.4 Any transferee of shares, pursuant to Article 5 or 6 hereof, shall execute this Agreement. Any such transferee shall become a member of the same category of Shareholders as its transferor. 5.5 Any Shareholder entitled to take action during a time period specified in this Article 5 may waive the duration of such period and agree to a time period of a shorter duration. 5.6 Immediately upon completion of the initial public offering of Common Stock of the Corporation, the provisions of this Article 5 shall apply only to the Corporation's Class C Common Stock and shall terminate with respect to all other classes of Common Stock. 5.7 For purposes of Article 5 and Article 6, the terms of any sale of Shares of one class or series of securities (the "First Securities") shall be deemed to be the same as those for another class or series of securities (the "Second Securities") if (i) (A) the consideration received in such sale for each Share of the First Securities divided by the number of Shares of common stock of the Corporation which each Share of the First Security could be converted into based on the relevant 19 conversion ratio for such security in effect immediately preceding such sale equals (B) the consideration received in such sale for each Share of the Second Securities divided by one (if the Second Security is common stock of the Corporation) or (in all other cases) the number of Shares of common stock for the Corporation which each Share of the Second Security could be converted into based on the exchange ratio for such security in effect immediately preceding such sale and (ii) all other terms of the sale of the First Securities and the Second Securities are the same. 5.8 Any party that acquires Shares of any First Reserve Shareholder or the Prudential Shareholder shall agree in writing to assume such party's obligations in respect of such shares under the Shareholders Put/Call Agreement of even date herewith in the event that such assumption is required by the terms of the Shareholder Put/Call Agreement. 5.9 For purposes of this Agreement, the following definitions shall apply: "Qualified Purchaser" means: (i) existing shareholders of the Corporation; (ii) insurance companies with assets of not less than $1,000,000,000; (iii) commercial banks and investments banks with 20 assets of not less than $1,000,000,000; and (iv) investment managers (including mutual funds and pension funds) with assets under management of not less than $1,000,000,000. "Change of Control" means the occurrence of any event which results in the number of directors of Petro's Board of Directors who are designated by the Sevin Group (in an individual or fiduciary capacity) in accordance with a shareholders agreement dated as of July 28, 1992 among Petro and certain shareholders constituting less than a majority of the Board. "Sevin Group" shall mean, collectively, the Estate of Malvin P. Sevin, Audrey L. Sevin, Irik P. Sevin, Thomas J. Edelman, Margot Gordon and Phillip Ean Cohen. 6. Tag Along Rights. (a)(i) If any Shareholder ----------------- entitled to sell Shares pursuant to Section 5.2 or 5.3 (the "Tag-along Offering Holders") receives from a third party or third parties (other than from an underwriter in connection with any public offering of Shares) a bona fide offer or offers to purchase or otherwise acquire, in one transaction or any series of similar transactions not subject to Section 5.1 (a "Tag-along Transfer Offer"), a number of Shares representing at least 5% of the then outstanding Shares (the "Tag-along Transfer Stock"), such Tag-along Offering Holders shall then cause the Tag-along 21 Transfer Offer to be reduced to writing and shall provide written notice (the "Tag-along Transfer Notice") of such Tag-along Transfer Offer to the Corporation and the Corporation shall provide written notice of such Tag-along Transfer Notice to each of the other Shareholders (the "Tag-along Transfer Offerees") in the manner set forth in this Section. The Tag-along Transfer Notice shall contain a true and correct copy of the Tag-along Transfer Offer. In addition, the Tag-along Transfer Notice shall identify the third party, the Tag-along Transfer Stock, the price contained in the Tag-along Transfer Offer, the estimated expenses associated with the sale, all the other terms and conditions of the Tag-along Transfer Offer and, in the case of a Tag-along Transfer Offer in which the consideration payable for Shares consists in part or in whole of consideration other than cash, such information as may be reasonably necessary to analyze the non-cash component of the consideration, together with the Tag-along Offering Holders' reasonable estimate of the fair value of such non-cash component. The Tag-along Transfer Offerees shall have the right and option, exercisable as set forth below, to accept the Tag-along Transfer Offer for up to such number of Shares as is determined in accordance with the provisions of this Section 6(a). The terms of any sale of Shares by a Tag-along Transfer Offeree pursuant to the exercise of its option under this Section shall be the same terms as those for the sale of such Shares by 22 the Tag-along Offering Holders; provided that any indemnity given -------- by the sellers to the purchasers in connection with such sale shall be apportioned among all the sellers according to the consideration to be received by each seller. Each Tag-along Transfer Offeree that desires to exercise such option shall provide the Tag-along Offering Holder with written irrevocable notice (specifying the number of shares of the Tag-along Transfer Stock as to which such Tag-along Transfer Offeree is accepting the offer) within 15 days after the date the Tag-along Transfer Notice is received ("Tag-along Notice Period"), and shall simultaneously provide a copy of such notice to the Corporation and the other Tag-along Transfer Offerees. Such written notice may not be withdrawn or modified at any time. At the expiration of the Tag-along Notice Period each accepting Tag-along Transfer Offeree shall, simultaneously with such expiration, deliver to the Corporation (or such other person as may be agreed between the Tag-along Offering Holder and the accepting Tag-along Transfer Offeree) to be held by such person for sale or return upon the terms of this Section 6, the certificate or certificates representing the Shares to be sold or otherwise disposed of pursuant to such Tag-along Transfer Offer by such Tag-along Transfer Offeree, duly endorsed, together with a limited power-of-attorney authorizing the Tag-along Offering Holder to sell or otherwise dispose of such Shares pursuant to the terms of the Tag-along Transfer Offer. 23 (ii) Each Tag-along Transfer Offeree shall have the right to sell, pursuant to the Tag-along Transfer Offer, an amount of Shares equal to the amount specified in such person's notice, or if less an amount of Shares equal to the product of (A) the total number of Shares of Tag-along Transfer Stock (including the shares of any Tag-along Transfer Offeree) to be sold pursuant to such Tag-along Transfer Offer, times (B) a fraction, the numerator of which shall be the total number of Shares held by such Tag-along Transfer Offeree, and the denominator of which shall be the total number of Shares held by all Tag-along Transfer Offerees that are accepting such Offer and the Tag-along Offering Holders. For purposes of this paragraph, Shares held by any Shareholder shall include (without duplication) Shares held by any affiliate of such shareholder, and Shares then issuable upon exercise of all warrants or options then held by such persons. The aggregate of such Shares for which Tag-along Transfer Offerees have elected to sell pursuant to this Section 6 shall be referred to as the "Tag-along Transfer Offeree Shares." (iii) Promptly after the consummation of the sale or other disposition of the Shares of the Tag-along Offering Holder and the Tag-along Transfer Offerees to the third party pursuant to the Tag-along Transfer Offer and in any event no later than one business day after such consummation, the Tag-along Offering Holder shall notify the Tag-along Transfer Offerees thereof, 24 shall remit to each of the Tag-along Transfer Offerees the total sales price of the Shares of such Tag-along Transfer Offeree sold or otherwise disposed of pursuant thereto (after deduction of such Tag-along Transfer Offeree's proportionate share of the out- of-pocket expenses associated with such sale based on the number of Shares sold by the Tag-along Offering Holder and each Tag-along Transfer Offeree), and shall furnish such other evidence of the expenses associated with and the completion and time of completion of such sale or other disposition and the terms thereof as may be reasonably requested by the Tag-along Transfer Offerees. (iv) If at the termination of the Tag-along Notice Period any Tag-along Transfer Offeree shall not have accepted the offer contained in the Tag-along Transfer Notice with respect to any Tag-along Transfer Offer, such Tag-along Transfer Offeree will be deemed to have waived any of and all of its rights under this Section 6 with respect to the sale or other disposition of its Tag-along Transfer Offeree Shares pursuant to such Tag-along Transfer Offer. The Tag-along Offering Holders shall have 120 days in which to sell the Tag-along Transfer Stock and Tag-along Transfer Offeree Shares not otherwise excluded pursuant to the previous sentence, to the third party, at a price not higher than that contained in the Tag-along Transfer Notice and on terms not more favorable to the Tag-along Offering Holder than were contained in the Tag-along Transfer Notice. Promptly after any 25 sale pursuant to this Section 6, the Tag-along Offering Holder shall notify the Corporation of the consummation thereof and shall furnish such evidence of the completion thereof (including time of completion) of such sale and of the terms of the terms thereof as the Corporation may request. If, at the end of such 60 day period (or such longer period, as aforesaid), the Tag-along Offering Holder has not completed the sale of all the Tag-along Transfer Stock and Tag-along Transfer Offeree Shares, the Tag-along Offering Holder shall return to such Tag-along Transfer Offerees all certificates representing the Shares which such Tag-along Transfer Offerees delivered for sale or other disposition pursuant to this Section 6(a), and all the restrictions on sale or other disposition contained in this Agreement with respect to Shares owned by the Tag-along Offering Holder shall again be in effect. (v) Notwithstanding anything contained in this Section 6, there shall be no liability on the part of the Tag-along Offering Holder to any Tag-along Transfer Offeree if the sale of Shares to a third party is not consummated for whatever reason. Whether to effect a sale of Shares pursuant to this Section 6 by the Tag-along Offering Holder is in the sole and absolute discretion of such Tag-along Offering Holder. (b) The failure by any Tag-along Transfer Offeree to exercise its First Offer Right or First Refusal Right pursuant to 26 Article 5 shall not affect the rights of such person to exercise its Tag-along rights pursuant to Article 6, including its right to exercise its Tag-along Rights in connection with the sale of Tag-along Transfer Stock. (c) The Tag-along Offering Holders shall cause any third party purchasing Shares hereunder to assume the obligations of the relevant Tag-along Transfer Offerees under the Shareholder Put/Call Agreement of even date herewith in respect of the relevant Shares. (d) The provisions of this Article 6 shall terminate immediately upon completion of the initial public offering of Common Stock of the Corporation. 7. Financial Statements. During the term of this -------------------- Agreement, the Corporation covenants and agrees that it shall furnish to each Shareholder (i) within ninety (90) days after the end of each fiscal year of the Corporation a consolidated balance sheet of the Corporation and its subsidiaries as at the end of such fiscal year and consolidated statements of income (loss), stockholders' equity and cash flows of the Corporation and its subsidiaries for such fiscal year audited by the Corporation's regularly employed, nationally-recognized firm of independent public accountants in accordance with generally accepted account- ing principles applied on the basis consistently maintained throughout the period involved, (ii) within forty-five (45) days after the close of each fiscal quarter the financial statements 27 referred to in clause "(i)" which shall be prepared by the Corporation and need not be covered by the report of any independent public accountants. With each quarterly and annual financial report, the Corporation shall deliver a list of shareholders including their respective equity security holdings. The Corporation shall deliver to each Shareholder a description of any action taken by written consent of directors or shareholders in lieu of a meeting promptly after such action is taken. The Corporation shall also deliver to each Shareholder a true and complete copy of each report, including but not limited to audit reports, review reports, special reports, reports on internal controls and management reports, submitted by a firm of certified public accountants to the Corporation or its board of directors promptly after the Corporation or board receives such report. Upon the request of any Shareholder, the Corporation shall promptly deliver to such Shareholder the information specified in paragraph (d)(4) of Rule 144A under the Securities Act of 1933. Additionally, during normal business hours, the Corporation shall permit each Shareholder reasonable access to the books and records of the Corporation and shall make available to representatives of each Shareholder, employees of the Corporation to explain such books and records and financial statements. The provisions of this Section shall terminate immediately upon a class of equity securities of the Corporation becoming subject to the periodic reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934. 28 8. The parties agree that it is impossible to determine the monetary damages which will accrue to a Shareholder by reason of a failure of any other Shareholder to perform any of the obligations under this Agreement requiring the performance of an act other than the payment of money only. Therefore, if any party hereto shall institute any action or proceeding in equity to enforce the provisions hereof, any person (including the Corporation) against whom such equitable action or proceeding is brought hereby waives the claim or defense therein that such party or such legal representative has an adequate remedy at law, and such person shall not urge in such equitable action or proceeding the claim or defense that such remedy at law exists. 9. In the event that any of the covenants, terms or conditions of this Agreement are held illegal and in the further event that director and/or shareholder action, including, but not by way of limitation, the execution of any documents or instru- ments, such as an amendment of the Certificate of Incorporation of the Corporation, will make such covenants, terms or conditions legal and enforceable, each of the parties hereto hereby agrees that he shall take such action as may reasonably be required to make any such covenant, term or condition valid and enforceable. In the event that any of the parties hereto refuses to take such action, the remaining Shareholders who are parties hereto are hereby jointly and severally appointed as the attorney-in-fact for the other Shareholders for the purpose of taking any action 29 that is authorized by the terms of this paragraph, including, but not limited to: (a) The voting of the other Shareholder's shares. (b) The removal of the Shareholder or his appointee(s) in breach of this paragraph as a director. (c) The nomination and election of a new director for the purpose of initiating and completing such action as may be required to make any illegal or unenforceable covenant, term or condition of this Agreement valid and enforceable. (d) The signing of any document or certificate, including, but not limited to an amendment to the Certificate of Incorporation of the Corporation, which will make said invalid and/or unenforceable covenant, term or condition valid and enforceable. 10. The Shareholders agree that the following legends shall be placed upon each certificate representing all or a portion of their Shares: "Transfer, hypothecation, negotiation, pledge, sale, encumbrance, assignment or other disposition of this share certificate and the shareholdings represented hereby are restricted by and are subject to all of the terms, conditions and provisions of a certain agreement entered into between certain of the shareholders and the Corporation as of December 21, 1993, as amended, a copy of which is on file with the Secretary at the principal office of the Corporation." 11. Any controversy arising out of or in any way relating to this Agreement including any modification or amend- 30 ment thereof, shall be resolved by arbitration in the City of New York, pursuant to the rules then obtaining of the American Arbi- tration Association. The parties agree that the arbitrators sitting in any such controversy shall have no power or jurisdic- tion to alter or modify any express provision of this Agreement, or to make any award which by its terms effects such alteration or modification. The parties hereto hereby consent to (a) the application of the Federal Arbitration Statutes (b) the jurisdic- tion of the Supreme Court of the State of New York and of the United States District Court for the Southern District of New York for all purposes in connection with said arbitration and (c) that any notice, process or notice of motion or other application to either of said Courts or Judges thereof or of any notice in connection therewith any arbitration hereunder, may be served in or out of the State or Southern District of New York by certified or registered mail return receipt requested or by personal ser- vice, provided a reasonable time for appearance is allowed, or in such other manner as may be permitted under the Rules of the American Arbitration Association or of either of said Courts. Judgment upon the award rendered may be entered by any court having jurisdiction.

None of the events referred to above shall effect any obligations theretofore incurred by the Corporation or any Share- holder pursuant to this Agreement. (b) This Agreement may be modified or rescinded only with the written consent of the Corporation and all of the Shareholders. 13. This Agreement contains the entire agreement of the parties concerning the subject matter hereof, and supersedes any and all prior agreements and amendments among the parties hereto concerning the subject matter hereof, which prior agreements are hereby canceled. The Shareholders Agreement, dated January 30, 1987, and as subsequently amended, between the Corporation and the First Reserve Shareholders has been terminated and canceled pursuant to a separate agreement. This Agreement shall terminate ten years from the date hereof and shall be automatically renewed for successive ten-year periods thereafter unless the parties hereto agree otherwise in writing. 32 14. If any provision of this Agreement is held invalid, such invalidity shall not affect the other provisions hereof which can be given effect without the invalid provision, and to this end the provisions of this Agreement are intended to be and shall be deemed severable. 15.
