2 Item 1. Description of Registrant's Securities to be Registered. On November 18, 1999 (the "Rights Dividend Declaration Date"), the Board of Directors of Berry Petroleum Company (the "Company") declared a dividend of one Right (a "Right") for each outstanding share of capital stock (Class A Common Stock "Common Stock" and Class B Stock) to be distributed to stockholders of record at the close of business on December 8, 1999 (the "Record Date"). Each Right entitles the registered holder to purchase from the Company one one-hundredth of a share (a "Unit") of Series B Junior Participating Preferred Stock, par value $0.01 per share (the "Preferred Stock"), at a Purchase Price of $38.00, subject to adjustment. The description and terms of the Rights are set forth in a Rights Agreement (the "Rights Agreement") between the Company and ChaseMellon Shareholder Services, LLC, as Rights Agent. The following is a brief description of the Rights. It is intended to provide a general description only and is qualified in its entirety by reference to the Rights Agreement, which is attached hereto as Exhibit 1. Capitalized terms not otherwise defined herein shall have the meanings given to them in the Rights Agreement. Issuance of Rights. Each share of Common Stock and Class B Stock outstanding at the close of business on the Record Date will receive one Right. In addition, prior to the Distribution Date (as hereinafter defined), one additional Right (as such number may be adjusted pursuant to the provisions of the Rights Agreement) shall be deemed to be delivered for each share of Common Stock and Class B Stock issued or transferred by the Company after the Record Date. Following the Distribution Date (as hereinafter defined) and prior to the expiration or redemption of the Rights, the Company will issue one Right (as such number may be adjusted pursuant to the provisions of the Rights Agreement) for each share of Common Stock issued pursuant to the exercise of stock options or under employee plans or upon the exercise, conversion or exchange of securities issued by the Company after the effective date of the Rights Agreement. In any other case after the Distribution Date, the Company may issue Rights when it issues capital stock if the Board of Directors deems it to be necessary or appropriate but shall be under no obligation to do so. Capital Stock Certificates Representing Rights Prior to Distribution Date. Prior to the Distribution Date, the Rights will be attached to all capital stock certificates representing shares then outstanding and will be transferred with and 2

3 only with such capital stock certificates. No separate Rights certificates will be distributed. The surrender for transfer of any certificates for capital stock outstanding will also constitute the transfer of the Rights associated with the capital stock represented by such certificate. New capital stock certificates issued after the Record Date will contain a legend incorporating the Rights Agreement by reference. Distribution Date. The Rights will separate from the capital stock and a Distribution Date will occur (the "Distribution Date") upon the earlier of (i) 10 days following a public announcement that a person or group of affiliated or associated persons, other than the Company, any subsidiary of the Company, any employee benefit plan or employee stock plan of the Company or any subsidiary of the Company, any person or entity organized, appointed or established by the Company for or pursuant to the terms of any such plan, or a person who or which, together with its Affiliates and Associates, shall become the Beneficial Owner of 20% or more of the shares of Common Stock then outstanding solely as a result of a reduction in the number of shares of Common Stock outstanding due to a repurchase of Common Stock by the Company, unless such person shall thereafter purchase or otherwise become the Beneficial Owner of additional shares of Common Stock representing 1% of the shares of Common Stock then outstanding (an "Exempt Person"), who or which, without the consent of the Company, has acquired or obtained the right to acquire, beneficial ownership of 20% or more of the outstanding shares of capital stock (such person or group being referred to as an "Acquiring Person" and such date being referred to as the "Stock Acquisition Date"), or (ii) 10 business days following the commencement of a tender offer or exchange offer that would result in a person or group (other than an Exempt Person or person approved by the Company) beneficially owning 20% or more of the outstanding shares of Common Stock. As soon as practicable after the Distribution Date, Rights certificates will be mailed to holders of record of the capital stock as of the close of business on the Distribution Date and, thereafter, the separate Rights certificates alone will represent the Rights. Exercise of Rights. Rights Initially Not Exercisable. Prior to the Distribution Date, the Rights are not exercisable. Rights Entitling Holders to Purchase Preferred Stock. At any time after the Distribution Date, but prior to the earlier of the expiration or redemption of the Rights, each Right may be exercised at the stated purchase price of $38.00 (subject 3

4 to adjustment) for one one-hundredth of a share of the Preferred Stock; provided, however, that upon the occurrence of any of the events described below the Rights may no longer be exercised for the Preferred Stock and may only be exercised for certain other securities described below. Rights Entitling Holders (Except Any Acquiring Person) to Purchase Common Stock of the Company. In the event that at any time following the Rights Dividend Declaration Date, a person becomes an Acquiring Person (except pursuant to an offer for all outstanding shares of Common Stock which a majority of the independent directors determines to be fair to and otherwise in the best interests of the Company and its stockholders), then each holder of a Right will thereafter have the right to receive, upon exercise, Common Stock (or, in certain circumstances, cash, property or other securities of the Company) having a value equal to two times the exercise price of the Right. The Rights are exercisable following the occurrence of the foregoing only at such time as the Rights are not redeemable by the Company. Notwithstanding any of the foregoing, following the occurrence of the event set forth in this Paragraph, all Rights that are, or (under certain circumstances specified in the Rights Agreement) were, beneficially owned by an Acquiring Person will be null and void. Rights Entitling Holders (Except Any Acquiring Person) to Purchase Common Stock of an Acquiring Company. In the event that, at any time following the Stock Acquisition Date, (i) the Company is acquired in a merger or other business combination transaction in which the Company is not the surviving corporation or in which the Company's outstanding Common Stock is exchanged for cash, stock or other property (other than a merger which follows an offer described in the preceding Paragraph), or (ii) 50% or more of the Company's assets or earning power is sold or transferred, each holder of a Right (except Rights which previously have been voided as set forth above) shall thereafter have the right to receive, upon exercise, common stock of the acquiring company having a value equal to two times the exercise price of the Right. Adjustment of Number of Rights, Purchase Price and Number of Units of Preferred Stock. The Purchase Price payable and/or the number of Units of Preferred Stock or other securities or property issuable upon exercise of the Rights are subject to adjustment from time to time to prevent dilution, as set forth in the Rights Agreement. With certain exceptions, no adjustment in the Purchase Price will be required until cumulative adjustments amount to at least 1% of the Purchase Price. 4

5 Fractional Rights and Fractional Shares. No fractional Rights, fractions of shares of Preferred Stock (other than fractions which are integral multiples of one one-hundredth of a share), or fractional shares of Common Stock will be issued and, in lieu thereof, an adjustment in cash will be made based on the market price of the Rights, Preferred Stock, or Common Stock, respectively, on the last trading date prior to the date of exercise. Redemption of Rights. In general, the Company may redeem the Rights in whole, but not in part, at a price of $0.01 per Right, at any time until the Distribution Date. Immediately upon the action of the Board of Directors ordering redemption of the Rights, the Rights will terminate and the only right of the holders of Rights will be to receive the $0.01 redemption price. After the Distribution Date, the Company's ability to redeem the Rights can be reinstated in certain circumstances, subject to certain conditions, in connection with a permitted transaction not involving an Acquiring Person or where an Acquiring Person has decreased its beneficial ownership in the Company to less than 10% of the then outstanding shares of Common Stock and there is no other Acquiring Person. Amendments. Other than those provisions relating to the redemption price or the final expiration date of the Rights, any of the provisions of the Rights Agreement may be supplemented or amended by the Company prior to the Distribution Date, without approval of the Rights holders, whether or not a supplement or amendment is adverse to the Rights holders. After the Distribution Date, the provisions of the Rights Agreement (other than those provisions relating to the redemption price or the final expiration date of the Rights) may be amended by the Company in order to make changes which do not materially and adversely affect the interests of holders of Rights (excluding the interests of any Acquiring Person). Final Expiration Date. The Rights will expire at the close of business on December 8, 2009, unless earlier redeemed or exchanged by the Company or terminated, as described in the Rights Agreement. No Voting or Dividend Rights. Until a Right is exercised, the holder thereof, as such, will have no rights as a 5

6 stockholder of the Company, including, without limitation, the right to vote or to receive dividends. Terms of the Preferred Stock. The Company has initially reserved 250,000 shares of Preferred Stock for issuance upon exercise of the Rights, such number to be subject to adjustment from time to time in accordance with the Rights Agreement. The Preferred Stock will be nonredeemable and will rank junior to all other series of the Company's preferred stock. The dividend, liquidation and voting rights, and the rights upon consolidation or merger of the Preferred Stock are designed so that the value of the one one-hundredth interest in a share of Preferred Stock purchasable with each Right will approximate the value of one share of Common Stock. Each whole share of Preferred Stock will be entitled to receive a quarterly preferential dividend of the greater of $.25 per share or 100 times the dividend declared on the Common Stock. In the event of liquidation, the holders of the Preferred Stock will be entitled to receive a preferential liquidation payment of $100 per share but will be entitled to receive, in the aggregate, a liquidation payment equal to 100 times the payment made per share of Common Stock. Each share of Preferred Stock will have 100 votes, voting together with the Common Stock. Finally, in the event of any merger, consolidation or other transaction in which shares of Common Stock are exchanged for or changed into other stock or securities, cash and/or other property, each share of Preferred Stock will be entitled to receive 100 times the amount received per share of Common Stock. Item 2. Exhibits. 1. Rights Agreement, dated as of December 8, 1999, by and between the Company and ChaseMellon Shareholder Services, LLC, as Rights Agent, which includes as Exhibit B thereto the Form of Rights Certificate. Pursuant to the terms of the Rights Agreement, Rights Certificates will not be mailed until after the Distribution Date ( as that term is defined in the Rights Agreement). 6

With respect to certificates for the Common Stock outstanding as of the Record Date, until the Distribution Date, the Rights will be evidenced by such certificates for the Common Stock and the registered holders of the Common Stock shall also be the registered holders of the associated Rights. Until the earlier of the Distribution Date or the Expiration Date, the transfer of any certificates representing shares of Common Stock in respect of which Rights have been issued shall also constitute the transfer of the Rights associated with such shares of Common Stock. (c) Rights shall be issued in respect of all shares of Common Stock which are issued after the Record Date but prior to the earlier of the Distribution Date or the Expiration Date. Certificates representing such shares of Common Stock (including, without limitation, certificates issued upon transfer or exchange of Common Stock) shall also be deemed to be certificates for Rights, and shall bear the following legend: This certificate also represents Rights that entitle the holder hereof to certain rights as set forth in a Rights Agreement between Berry Petroleum Company (the "Company") and ChaseMellon Shareholder Services, L.L.C., as Rights Agent, dated as of December 8, 1999 (the "Rights Agreement"), the terms, conditions and limitations of which are hereby incorporated herein by reference and a copy of which is on file at the principal offices of the Company. Under certain circumstances, as set forth in the Rights Agreement, such Rights will be evidenced by separate certificates and will no longer be evidenced by this certificate. The Company will mail to the holder of this certificate a copy of the Rights Agreement, as in effect on the date of mailing, without charge promptly after receipt of a written request therefor. Under certain circumstances set forth in the Rights Agreement, Rights issued to, or beneficially owned by, any Person who is, was or becomes an Acquiring Person or any Affiliate or Associate thereof (as such terms are defined in the Rights Agreement), whether currently held by or on behalf of such Person or by any subsequent holder, may become null and void and no longer transferable. With respect to such certificates containing the foregoing legend, the Rights associated with the Common Stock represented by such certificates shall, until the Distribution Date, be evidenced by such certificates alone and registered holders of Common Stock shall also be the registered holders of the associated Rights, and the transfer of any of 7

8 such certificates shall also constitute the transfer of the Rights associated with the Common Stock represented by such certificates. Section 4. Form of Rights Certificates. (a) The Rights Certificates (and the forms of an election to purchase and of assignment and of certificates to be printed on the reverse thereof) when, as and if issued, shall each be substantially in the form set forth in Exhibit B hereto and may have such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Company may deem appropriate which do not affect the duties or responsibilities of the Rights Agent and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange on which the Rights may from time to time be listed, or to conform to usage. Subject to the provisions of Section 11 and Section 22 hereof, the Rights Certificates, whenever distributed, shall be dated as of the Record Date and on their face shall entitle the holders thereof to purchase such number of one one-hundredth of a share of Preferred Stock as shall be set forth therein at the price set forth therein (such exercise price per one one-hundredth of a share, the "Purchase Price"), but the amount and type of securities purchasable upon the exercise of each Right and the Purchase Price thereof shall be subject to adjustment as provided herein. (b) Notwithstanding any other provision of this Agreement, any Rights Certificate issued pursuant to Section 3(a) or Section 22 hereof that represents Rights beneficially owned by any Person known to be: (i) an Acquiring Person or any Associate or Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee after the Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee prior to or concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person to holders of equity interests in such Acquiring Person or to any Person with whom such Acquiring Person has any continuing agreement, arrangement or understanding regarding the transferred Rights or (B) a transfer which the Board of Directors of the Company has determined is part of a plan, arrangement or understanding which has as a primary purpose or effect avoidance of Section 7(e) hereof, and any Rights Certificate issued pursuant to Section 6 or Section 11 hereof upon transfer, exchange, replacement or adjustment of any other Rights Certificate referred to in this sentence, shall contain (to the extent feasible) the following legend, modified as applicable to apply to such Person: The Rights represented by this Rights Certificate are or were beneficially owned by a Person who was or became an Acquiring Person or an Affiliate or Associate of an Acquiring 8

9 Person (as such terms are defined in the Rights Agreement). Accordingly, this Rights Certificate and the Rights represented hereby may become null and void in the circumstances specified in Section 7(e) of such Agreement. The provisions of Section 7(e) of this Agreement shall be operative whether or not the foregoing legend is contained on any such Rights Certificate. The Company shall give notice to the Rights Agent promptly after it becomes aware of the existence of any Acquiring Person or any Associate or Affiliate thereof. Section 5. Countersignature and Registration. (a) The Rights Certificates shall be executed on behalf of the Company by its Chairman of the Board, its President or any Vice President, either manually or by facsimile signature, and shall have affixed thereto the Company's seal or a facsimile thereof which shall be attested by the Secretary or an Assistant Secretary of the Company, either manually or by facsimile signature. The Rights Certificates shall be manually countersigned by the Rights Agent and shall not be valid for any purpose unless so countersigned. In case any officer of the Company who shall have signed any of the Rights Certificates shall cease to be such officer of the Company before countersignature by the Rights Agent and issuance and delivery by the Company, such Rights Certificates, nevertheless, may be countersigned by the Rights Agent and issued and delivered by the Company with the same force and effect as though the person who signed such Rights Certificates had not ceased to be such officer of the Company; and any Rights Certificates may be signed on behalf of the Company by any person who, at the actual date of the execution of such Rights Certificate shall be a proper officer of the Company to sign such Rights Certificate, although at the date of the execution of this Rights Agreement any such person was not such an officer. (b) Following the Distribution Date, and receipt by the Rights Agent of all necessary information, the Rights Agent will keep or cause to be kept, at its office designated as the appropriate place for surrender of Rights Certificates upon exercise or transfer, books for registration and transfer of the Rights Certificates issued hereunder. Such books shall show the names and addresses of the respective holders of the Rights Certificates, the number of Rights evidenced on its face by each of the Rights Certificates and the certificate number and the date of each of the Rights Certificates. 9

10 Section 6. Transfer, Split Up, Combination and Exchange of Rights Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates. (a) Subject to the provisions of Section 4(b), Section 7(e), Section 14 and Section 24 hereof, at any time after the Close of Business on the Distribution Date, and at or prior to the Close of Business on the Expiration Date, any Rights Certificate or Certificates may be transferred, split up, combined or exchanged for another Rights Certificate or Certificates, entitling the registered holder to purchase a like number of one one-hundredth of a share of Preferred Stock (or, following a Triggering Event, Common Stock, other securities, cash or other assets, as the case may be) as the Rights Certificate or Certificates surrendered then entitled such holder (or former holder in the case of a transfer) to purchase. Any registered holder desiring to transfer, split up, combine or exchange any Rights Certificate or Certificates shall make such request in writing delivered to the Rights Agent, and shall surrender the Rights Certificate or Certificates to be transferred, split up, combined or exchanged at the office or offices of the Rights Agent designated for such purpose. Neither the Rights Agent nor the Company shall be obligated to take any action whatsoever with respect to the transfer of any such surrendered Rights Certificate until the registered holder shall have completed and signed the certificate contained in the form of assignment on the reverse side of such Rights Certificate and shall have provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates thereof as the Company shall reasonably request. Thereupon the Rights Agent shall, countersign and deliver to the Person entitled thereto a Rights Certificate or Rights Certificates, as the case may be, as so requested. The Company may require payment of a sum sufficient to cover any tax or charge that may be imposed in connection with any transfer, split up, combination or exchange of Rights Certificates. The Rights Agent shall have no duty or obligation under this Section unless and until it is satisfied that all such taxes and/or charges have been paid. (b) Upon receipt by the Company and the Rights Agent of evidence reasonably satisfactory to them of the loss, theft, destruction or mutilation of a Rights Certificate, and, in case of loss, theft or destruction, of indemnity or security satisfactory to them, and reimbursement to the Company and the Rights Agent of all reasonable expenses incidental thereto, and upon surrender to the Rights Agent and cancellation of the Rights Certificate if mutilated, the Company will execute and deliver a new Rights Certificate of like tenor to the Rights Agent for countersignature and delivery to the registered owner in lieu of the Rights Certificate so lost, stolen, destroyed or mutilated. Section 7. Exercise of Rights; Purchase Price; Expiration Date of Rights. (a) Subject to Section 7(e) hereof, the registered holder of any Rights Certificate may exercise the Rights evidenced thereby (except as otherwise provided 10

11 herein including, without limitation, the restrictions on exercisability set forth in Section 9(c), Section 11(a)(iii) and Section 23(a) hereof), in whole or in part at any time after the Distribution Date upon surrender of the Rights Certificate, with the form of election to purchase and the certificate on the reverse side thereof duly and properly executed, to the Rights Agent at the office of the Rights Agent designated as the appropriate place for such purpose, together with payment of the aggregate Purchase Price with respect to the total number of one one-hundredth of a share of Preferred Stock (or other securities, cash or other assets, as the case may be) as to which such surrendered Rights are then exercisable, at or prior to the earliest of (i) the Final Expiration Date, (ii) the time at which the Rights are redeemed as provided in Section 23 hereof, (iii) the time at which the Rights are exchanged as provided in Section 24 hereof, or (iv) the time at which the Rights expire as provided in Section 13(d) hereof (the earliest of (i) through (iv) being herein referred to as the "Expiration Date"). (b) The Purchase Price for each one one-hundredth of a share of Preferred Stock pursuant to the exercise of a Right shall initially be $38.00, and shall be subject to adjustment from time to time as provided in Sections 11 and 13(a) hereof and shall be payable in accordance with paragraph(c) below. (c) Upon receipt of a Rights Certificate representing exercisable Rights, with the form of election to purchase and the certificate duly and properly executed, accompanied by payment, with respect to each Right so exercised, of the Purchase Price per one one-hundredth of a share of Preferred Stock (or other shares, securities, cash or other assets, as the case may be) to be purchased as set forth below and an amount equal to any applicable transfer tax, the Rights Agent shall, thereupon promptly (i) (A) requisition from any transfer agent of the shares of Preferred Stock (or make available, if the Rights Agent is the transfer agent for such shares) certificates for the total number of one one-hundredth of a share of Preferred Stock to be purchased and the Company hereby authorizes its transfer agent to comply with all such requests, or (B) if the Company shall have elected to deposit the total number of shares of Preferred Stock issuable upon exercise of the Rights hereunder with a depositary agent, requisition from the depositary agent depositary receipts representing such number of one one-hundredth of a share of Preferred Stock as are to be purchased (in which case certificates for the shares of Preferred Stock represented by such receipts shall be deposited by the transfer agent with the depositary agent) and the Company will direct the depositary agent to comply with such request, (ii) requisition from the Company an amount of cash, if any, to be paid in lieu of fractional shares in accordance with Section 14 hereof, (iii) after receipt of such certificates or depositary receipts, cause the same to be delivered to or upon the order of the registered holder of such Rights Certificate, registered in such name or names as may be designated by such holder, and (iv) after receipt thereof, deliver such cash, if any, to or upon the order of the registered holder of such Rights Certificate. The payment of the Purchase Price (as such amount may be reduced pursuant to Section 11(a)(iii) hereof) may be made by 11

12 bank draft, certified bank check or money order payable to the order of the Company. In the event that the Company is obligated to issue other securities (including Common Stock) of the Company, pay cash and/or distribute other property pursuant to Section 11(a) hereof, the Company will make all arrangements necessary so that such other securities, cash and/or other property are available for distribution by the Rights Agent, if and when appropriate. (d) In case the registered holder of any Rights Certificate shall exercise less than all the Rights evidenced thereby, a new Rights Certificate evidencing Rights equivalent to the Rights remaining unexercised shall be issued by the Rights Agent and delivered to, or upon the order of, the registered holder of such Rights Certificate, registered in such name or names as may be designated by such holder, subject to the provisions of Section 14 hereof. (e) Notwithstanding anything in this Agreement to the contrary, from and after the occurrence of a Section 11(a)(ii) Event, any Rights beneficially owned by (i) an Acquiring Person or an Associate or Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee after the Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee prior to or concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) by or for the Acquiring Person to holders of equity interests in such Acquiring Person or to any Person with whom the Acquiring Person has any continuing agreement, arrangement or understanding regarding the transferred Rights or (B) a transfer which the Board of Directors of the Company has determined is part of a plan, arrangement or understanding which has as a primary purpose or effect the avoidance of this Section 7(e), shall become null and void without any further action and no holder of such Rights shall have any rights whatsoever with respect to such Rights, whether under any provision of this Agreement or otherwise. The Company shall use all reasonable efforts to insure that the provisions of this Section 7(e) and Section 4(b) hereof are complied with, but shall have no liability to any holder of Rights Certificates or other Person as a result of its failure to make any determinations with respect to an Acquiring Person or any of their respective Affiliates, Associates or transferees hereunder. (f) Notwithstanding anything in this Agreement to the contrary, neither the Rights Agent nor the Company shall be obligated to undertake any action with respect to a registered holder upon the occurrence of any purported exercise as set forth in this Section 7 unless such registered holder shall have (i) completed and signed the certificate contained in the form of election to purchase set forth on the reverse side of the Rights Certificate surrendered for such exercise, and (ii) provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or 12

13 Affiliates or Associates thereof as the Company or the Rights Agent shall reasonably request. Section 8. Cancellation and Destruction of Rights Certificates. All Rights Certificates surrendered for the purpose of exercises, transfer, split up, combination or exchange shall, if surrendered to the Company or any of its agents, be delivered to the Rights Agent for cancellation or in canceled form, or, if surrendered to the Rights Agent, shall be canceled by it, and no Rights Certificates shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Agreement. The Company shall deliver to the Rights Agent for cancellation and retirement, and the Rights Agent shall so cancel and retire, any other Rights Certificate purchased or acquired by the Company otherwise than upon the exercise thereof. The Rights Agent shall deliver all canceled Rights Certificates to the Company, or shall, at the written request of the Company, destroy such canceled Rights Certificates, and in such case shall deliver a certificate of destruction thereof to the Company. Section 9. Reservation and Availability of Capital Stock. (a) The Company covenants and agrees that it will cause to be reserved and kept available out of its authorized and unissued shares of Preferred Stock (and, following the occurrence of a Triggering Event, out of its authorized and unissued shares of Common Stock and/or other securities or out of its authorized and issued shares held in its treasury), the number of shares of Preferred Stock (and, following the occurrence of a Triggering Event, Common Stock and/or other securities) that, as provided in this Agreement including Section 11(a)(iii) hereof, will be sufficient to permit the exercise in full of all outstanding Rights, provided, however, that the Company shall not be required to reserve and keep available shares of Preferred Stock, Common Stock or other securities sufficient to permit the exercise in full of all outstanding Rights pursuant to the adjustments set forth in Section 11(a)(ii), Section 11(a)(iii) or Section 13 hereof unless, and only to the extent that, the Rights become exercisable pursuant to such adjustments. (b) So long as the shares of Preferred Stock (and, following the occurrence of a Triggering Event, Common Stock and/or other securities) issuable and deliverable upon the exercise of Rights may be listed on any national securities exchange, the Company shall use its best efforts to cause, from and after such time as the Rights become exercisable, all shares reserved for such issuance to be listed on such exchange upon official notice of issuance upon such exercise. (c) If necessary to permit the offer and issuance of Preferred Stock (and, following the occurrence of a Triggering Event, Common Stock and/or other securities)issuable and deliverable upon the exercise of Rights, the Company shall use its best efforts to (i) file, as soon as practicable following the earliest date after the occurrence 13

14 of a Section 11(a)(ii) Event on which the consideration to be delivered by the Company upon exercise of the Rights has been determined in accordance with Section 11(a)(iii) hereof, or as soon as is required by law following the Distribution Date, as the case may be, a registration statement under the Act, with respect to the securities purchasable upon exercise of the Rights on an appropriate form, (ii) cause such registration statement to become effective as soon as practicable after such filing, and (iii) cause such registration statement to remain effective (with a prospectus at all times meeting the requirements of the Act) until the earlier of (A) the date as of which the Rights are no longer exercisable for such securities, and (B) the date of the expiration of the Rights. The Company will also take such action as may be appropriate under, or to ensure compliance with, the securities or "Blue Sky" laws of the various states in connection with the exercisability of the Rights. The Company may temporarily suspend, for a period of time not to exceed ninety (90) days after the date set forth in clause (i) of the first sentence of this Section 9(c), the exercisability of the Rights in order to prepare and file such registration statement and permit it to become effective. Upon any such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect with prompt notice thereof to the Rights Agent. Notwithstanding any provision of this Agreement to the contrary, the Rights shall not be exercisable in any jurisdiction, unless the requisite qualification in such jurisdiction shall have been obtained and until a registration statement (if required) has been declared effective. (d) The Company covenants and agrees that it will take all such action as may be necessary to ensure that all one one-hundredth of a share of Preferred Stock (and, following the occurrence of a Triggering Event, Common Stock and/or other securities) delivered upon exercise of Rights shall, at the time of delivery of the certificates for such shares (subject to payment of the Purchase Price), be duly and validly authorized and issued and fully paid and nonassessable. (e) The Company further covenants and agrees that it will pay when due and payable any and all taxes and charges which may be payable in respect of the issuance or delivery of the Rights Certificates and of any certificates for a number of one one-hundredth of a share of Preferred Stock (or Common Stock and/or other securities, as the case may be) upon the exercise of Rights. The Company shall not, however, be required to pay any tax or charge which may be payable in respect of any transfer or delivery of Rights Certificates to a Person other than, or the issuance or delivery of a number of one one-hundredth of a share of Preferred Stock (or Common Stock and/or other securities, as the case may be) in respect of a name other than that of, the registered holder of the Rights Certificates evidencing Rights surrendered for exercise or to issue or deliver any certificates for a number of one one-hundredth of a share of Preferred Stock (or Common Stock and/or other securities, as the case may be) in a name other than that of the registered holder upon the exercise of any Rights until 14

15 such tax or charge shall have been paid (any such tax or charge being payable by the holder of such Rights Certificate at the time of surrender) or until it has been established to the Company's satisfaction that no such tax or charge is due. Section 10. Preferred Stock Record Date. Each person in whose name any certificate for a number of one one-hundredth of a share of Preferred Stock (or Common Stock and/or other securities, as the case may be) is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of such fractional shares of Preferred Stock (or Common Stock and/or other securities, as the case may be) represented thereby and such certificate shall be dated, the date upon which the Rights Certificate evidencing such Rights was duly surrendered and payment of the Purchase Price (and all applicable taxes or charges) was made; provided, however, that if the date of such surrender and payment is a date upon which the Preferred Stock (or Common Stock and/or other securities, as the case may be) transfer books of the Company are closed, such Person shall be deemed to have become the record holder of such shares (fractional or otherwise) on, and such certificate shall be dated, the next succeeding Business Day on which the Preferred Stock (or Common Stock and/or other securities, as the case may be) transfer books of the Company are open. Prior to the exercise of the Rights evidenced thereby, the holder of a Rights Certificate, as such, shall not be entitled to any rights of a stockholder of the Company with respect to shares for which the Rights shall be exercisable, including, without limitation, the right to vote, to receive dividends or other distributions or to exercise any preemptive rights, and shall not be entitled to receive any notice of any proceedings of the Company, except as provided herein. Section 11. Adjustment of Purchase Price, Number and Kind of Shares or Number of Rights. The Purchase Price, the number and kind of shares covered by each Right and the number of Rights outstanding are subject to adjustment from time to time as provided in this Section 11. (a) (i) In the event the Company shall at any time after the date of this Agreement (A) declare a dividend on the Preferred Stock payable in shares of Preferred Stock, (B) subdivide the outstanding Preferred Stock, (C) combine the outstanding Preferred Stock into a smaller number of shares, or (D) issue any shares of its capital stock in a reclassification of the Preferred Stock (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing or surviving corporation), except as otherwise provided in this Section 11(a) and Section 7(e) hereof, the Purchase Price in effect at the time of the record date for such dividend or of the effective date of such subdivision, combination or reclassification, and the number and kind of shares of Preferred Stock or capital stock, as the case may be, issuable on such date, shall be proportionately adjusted so that the holder of any Right exercised after such time shall be entitled to receive, upon payment of the Purchase Price then in effect, the aggregate number and kind of shares of Preferred Stock or 15

16 capital stock, as the case may be, which, if such Right had been exercised immediately prior to such date and at a time when the Preferred Stock transfer books of the Company were open, he would have owned upon such exercise and been entitled to receive by virtue of such dividend, subdivision, combination or reclassification. If an event occurs which would require an adjustment under both this Section 11(a)(i) and Section 11(a)(ii) hereof, the adjustment provided for in this Section 11(a)(i) shall be in addition to, and shall be made prior to, any adjustment required pursuant to Section 11(a)(ii) hereof. (ii) Subject to Section 24 of this Agreement, in the event any Acquiring Person, alone or together with its Affiliates and Associates, shall, at any time after the Rights Dividend Declaration Date, become the Beneficial Owner of 20% or more of the shares of Common Stock then outstanding, unless the event causing the 20% threshold to be crossed is a transaction set forth in Section 13(a) hereof, or is an acquisition of shares of Common Stock pursuant to a tender offer or an exchange offer for all outstanding shares of Common Stock at a price and on terms determined by at least a majority of the members of the Board of Directors who are not officers of the Company and who are not representatives, nominees, Affiliates or Associates of an Acquiring Person, after receiving advice from one or more investment banking firms to be (a) at a price which is fair to stockholders of the Company (taking into account all factors which such members of the Board deem relevant including, without limitation, prices which could reasonably be achieved if the Company or its assets were sold on an orderly basis designed to realize maximum value) and (b) otherwise in the best interests of the Company and its stockholders, then, proper provision shall be made so that each holder of a Right (except as provided below and in Section 7(e) hereof) shall thereafter have the right to receive, upon exercise thereof at the then current Purchase Price in accordance with the terms of this Agreement, in lieu of a number of one one-hundredth of a share of Preferred Stock, such number of shares of Common Stock of the Company as shall equal the result obtained by (x) multiplying the then current Purchase Price by the then number of one one-hundredth of a share of Preferred Stock for which a Right was exercisable immediately prior to the occurrence of a Section 11(a)(ii) Event, and (y) dividing that product (which, following such occurrence, shall thereafter be referred to as the "Purchase Price" for each Right and for all purposes of this Agreement) by 50% of the current market price (determined pursuant to Section 11(d) hereof) per share of Common Stock on the date of such occurrence (such number of shares is herein called the "Adjustment Shares"); provided that the Purchase Price and the number of Adjustment Shares shall be further adjusted as provided in this Agreement to reflect any events occurring after the date of such occurrence; and provided, further, that if the transaction that would otherwise give rise to the foregoing adjustment is also subject to the provisions of Section 13 hereof, then only the provisions of Section 13 hereof shall apply and no adjustment shall be made pursuant to this Section 11(a)(ii). 16

17 (iii) In the event that the number of shares of Common Stock which are authorized by the Company's certificate of incorporation but not outstanding or reserved for issuance for purposes other than upon exercise of the Rights is not sufficient to permit the exercise in full of the Rights in accordance with the foregoing subparagraph (ii) of this Section 11(a) and the Rights shall become so exercisable, to the extent permitted by applicable law and any agreements in effect on the date hereof to which the Company is a party, the Company shall: (A) determine the excess of (1) the value of the Adjustment Shares issuable upon the exercise of a Right (the "Current Value") over (2) the Purchase Price (such excess, the "Spread"), and (B) with respect to each Right, make adequate provision to substitute for the Adjustment Shares, upon payment of the applicable Purchase Price, (1) cash, (2) a reduction in the Purchase Price, (3) Common Stock or other equity securities of the Company (including, without limitation, shares, or units of shares, of preferred stock which the Board of Directors of the Company has deemed to have the same value as shares of Common Stock (such shares of preferred stock, "common stock equivalents")), (4) debt securities of the Company, (5) other assets, or (6) any combination of the foregoing, having an aggregate value equal to the Current Value, where such aggregate value has been determined by the Board of Directors of the Company based upon the advice of a nationally recognized investment banking firm selected by the Board of Directors of the Company; provided, however, if the Company shall not have made adequate provision to deliver value pursuant to clause (B) above within thirty (30) days following the later of (x) the occurrence of a Section 11(a)(ii) Event and (y) the date on which the Company's right of redemption pursuant to Section 23(a) expires (the later of (x) and (y) being referred to herein as the ASection 11(a)(ii) Trigger Date"), then the Company shall be obligated to deliver, upon the surrender for exercise of a Right and without requiring payment of the Purchase Price, shares of Common Stock (to the extent available) and then, if necessary, cash, which shares and/or cash have an aggregate value equal to the Spread. If the Board of Directors of the Company shall determine in good faith that it is likely that sufficient additional shares of Common Stock could be authorized for issuance upon exercise in full of the Rights, the thirty (30) day period set forth above may be extended to the extent necessary, but not more than ninety (90) days after the Section 11(a)(ii) Trigger Date, in order that the Company may seek stockholder approval for the authorization of such additional shares (such period, as it may be extended, the "Substitution Period"). To the extent that the Company determines that some action need be taken pursuant to the first and/or second sentences of this Section 11(a)(iii), the Company (x) shall provide, subject to Section 7(e) hereof, that such action shall apply uniformly to all outstanding Rights, and (y) may suspend the exercisability of the Rights until the expiration of the Substitution Period in order to seek any authorization of additional shares and/or to decide the appropriate form of distribution to be made pursuant to such first sentence and to determine the value thereof. In the event of any such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect in each case 17

18 with prompt notice thereof to the Rights Agent. For purposes of this Section 11(a)(iii), the value of the Common Stock shall be the current market price (as determined pursuant to Section 11(d) hereof) per share of the Common Stock on the Section 11(a)(ii) Trigger Date and the value of any "common stock equivalent" shall be deemed to have the same value as the Common Stock on such date. The Board of Directors may, but shall not be required to, establish procedures to allocate the right to receive Common Stock upon the exercise of Rights pursuant to this Section 11(a)(iii). (b) In case the Company shall fix a record date for the issuance of rights (other than the Rights), options or warrants to all holders of Preferred Stock entitling them to subscribe for or purchase (for a period expiring within forty-five (45) calendar days after such record date) Preferred Stock (or shares having the same rights, privileges and preferences as the shares of Preferred Stock ("equivalent preferred stock") or securities convertible into Preferred Stock or equivalent preferred stock at a price per share of Preferred Stock or per share of equivalent preferred stock (or having a conversion price per share, if a security convertible into Preferred Stock or equivalent preferred stock) less than the current market price (as determined pursuant to Section 11(d) hereof) per share of Preferred Stock on such record date, the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the number of shares of Preferred Stock outstanding on such record date, plus the number of shares of Preferred Stock which the aggregate offering price of the total number of shares of Preferred Stock (and/or equivalent preferred stock so to be offered and/or the aggregate initial conversion price of the convertible securities so to be offered) would purchase at such current market price, and the denominator of which shall be the number of shares of Preferred Stock outstanding on such record date, plus the number of additional shares of Preferred Stock and/or equivalent preferred stock to be offered for subscription or purchase (or into which the convertible securities so to be offered are initially convertible). In case such subscription price may be paid by delivery of consideration part or all of which may be in a form other than cash, the value of such consideration shall be as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of the Rights. Shares of Preferred Stock owned by or held for the account of the Company shall not be deemed outstanding for the purpose of any such computation. Such adjustment shall be made successively whenever such a record date is fixed, and in the event that such rights or warrants are not so issued, the Purchase Price shall be adjusted to be the Purchase Price which would then be in effect if such record date had not been fixed. (c) In case the Company shall fix a record date for a distribution to all holders of Preferred Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation) of 18

19 evidences of indebtedness, cash (other than a regular quarterly cash dividend out of the earnings or retained earnings of the Company), assets (other than a dividend payable in Preferred Stock, but including any dividend payable in stock other than Preferred Stock) or subscription rights or warrants (excluding those referred to in Section 11(b) hereof), the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the current market price (as determined pursuant to Section 11(d) hereof) per share of Preferred Stock on such record date, less the fair market value (as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent) of the portion of the cash, assets or evidences of indebtedness so to be distributed or of such subscription rights or warrants applicable to a share of Preferred Stock and the denominator of which shall be such current market price (as determined pursuant to Section 11(d) hereof per share of Preferred Stock. Such adjustments shall be made successively whenever such a record date is fixed, and in the event that such distribution is not so made, the Purchase Price shall be adjusted to be the Purchase Price which would have been in effect if such record date had not been fixed. (d) (i) For the purpose of any computation hereunder, other than computations made pursuant to Section 11(a)(iii) hereof, the "current market price" per share of Common Stock on any date shall be deemed to be the average of the daily closing prices per share of such Common Stock for the thirty (30) consecutive Trading Days (as such term is hereinafter defined) immediately prior to but not including such date, and for purposes of computations made pursuant to Section 11(a)(iii) hereof, the "current market price" per share of Common Stock on any date shall be deemed to be the average of the daily closing prices per share of such Common Stock for the ten (10) consecutive Trading Days immediately following such date; provided, however, that in the event that the current market price per share of the Common Stock is determined during a period following the announcement by the issuer of such Common Stock of (A) a dividend or distribution on such Common Stock payable in shares of such Common Stock or securities convertible into shares of such Common Stock (other than the Rights), or (B) any subdivision, combination or reclassification of such Common Stock, and prior to the expiration of the requisite thirty (30) Trading Day or ten (10) Trading Day period, as set forth above, after but not including the ex-dividend date for such dividend or distribution, or the record date for such subdivision, combination or reclassification, then, and in each such case, the "current market price" shall be properly adjusted to take into account ex-dividend trading. The closing price for each day shall be the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the shares of Common Stock are not listed or admitted to trading on the New York Stock Exchange, as reported in the principal consolidated transaction reporting system with 19

20 respect to securities listed on the principal national securities exchange on which the shares of Common Stock are listed or admitted to trading or, if the shares of Common Stock are not listed or admitted to trading on any national securities exchange the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over- the-counter market, as reported by the National Association of Securities Dealers, Inc. Automated Quotation System ("NASDAQ") or such other system then in use, or, if on any such date the shares of Common Stock are not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Common Stock selected by the Board of Directors of the Company. If on any such date no market maker is making a market in the Common Stock, the fair value of such shares on such date as determined in good faith by the Board of Directors of the Company shall be used. The term "Trading Day" shall mean a day on which the principal national securities exchange on which the shares of Common Stock are listed or admitted to trading is open for the transaction of business or, if the shares of Common Stock are not listed or admitted to trading on any national securities exchange, a Business Day. If the Common Stock is not publicly held or not so listed or traded, "current market price" per share shall mean the fair value per share as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes. (ii) For the purpose of any computation hereunder, the "current market price" per share of Preferred Stock shall be determined in the same manner as set forth above for the Common Stock in clause (i) of this Section 11(d) (other than the last sentence thereof). If the current market price per share of Preferred Stock cannot be determined in the manner provided above or if the Preferred Stock is not publicly held or listed or traded in a manner described in clause (i) of this Section 11(d), the "current market price" per share of Preferred Stock shall be conclusively deemed to be an amount equal to 100 (as such number may be appropriately adjusted for such events as stock splits, stock dividends and recapitalizations with respect to the Common Stock occurring after the date of this Agreement) multiplied by the current market price per share of the Common Stock. If neither the Common Stock nor the Preferred Stock is publicly held or so listed or traded, "current market price" per share of the Preferred Stock shall mean the fair value per share as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes. For all purposes of this Agreement, the "current market price" to one one-hundredth of a share of Preferred Stock shall be equal to the "current market price" of one share of Preferred Stock divided by 100. (e) Anything herein to the contrary notwithstanding, no adjustment in the Purchase Price shall be required unless such adjustment would require an increase or decrease of at least one percent (1%) in the Purchase Price; provided, however, that any 20

21 adjustments which by reason of this Section 11(e) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 11 shall be made to the nearest cent or to the nearest ten-thousandth of a share of Common Stock or other share or one-millionth of a share of Preferred Stock, as the case may be. Notwithstanding the first sentence of this Section 11(e), an adjustment required by this Section 11 shall be made no later than the earlier of (i) three (3) years from the date of the transaction which mandates such adjustments, or (ii) the Expiration date. (f) If as a result of an adjustment made pursuant to Section 11(a)(ii) or Section 13(a) hereof, the holder of any Right thereafter exercised shall become entitled to receive any shares of capital stock other than Preferred Stock, thereafter the number of such other shares so receivable upon exercise of any Right and the Purchase Price thereof shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Preferred Stock contained in Sections 11(a), (b), (c), (e), (g), (h), (i), (j), (k), and (m), and the provisions of Sections 7, 9, 10, 13 and 14 hereof with respect to the Preferred Stock shall apply on like terms to any such other shares. (g) All Rights originally issued by the Company subsequent to any adjustment made to the Purchase Price hereunder shall evidence the right to purchase, at the adjusted Purchase Price, the number of one one-hundredth of a share of Preferred Stock purchasable from time to time hereunder upon exercise of the Rights, all subject to further adjustment as provided herein. (h) Unless the Company shall have exercised its election as provided in Section 11(i), upon each adjustment of the Purchase Price as a result of the calculations made in Sections 11(b) and (c), each Right outstanding immediately prior to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted Purchase Price, that number of one one-hundredth of a share of Preferred Stock (calculated to the nearest one-ten-thousandth) obtained by (i) multiplying (x) the number of one one-hundredth of a share covered by a Right immediately prior to this adjustment, by (y) the Purchase Price in effect immediately prior to such adjustment of the Purchase Price, and (ii) dividing the product so obtained by the Purchase Price in effect immediately after such adjustment of the Purchase Price. (i) The Company may elect on or after the date of any adjustment of the Purchase Price to adjust the number of Rights, in lieu of any adjustment in the number of one one-hundredth of a share of Preferred Stock purchasable upon the exercise of a Right. Each of the Rights outstanding after the adjustment in the number of Rights shall be exercisable for the number of one one-hundredth of a share of Preferred Stock for which a Right was exercisable immediately prior to such adjustment. Each Right held of record prior to such adjustment of the number of Rights shall become that 21

22 number of Rights (calculated to the nearest one-ten-thousandth) obtained by dividing the Purchase Price in effect immediately prior to adjustment of the Purchase Price by the Purchase Price in effect immediately after adjustment of the Purchase Price. The Company shall make a public announcement of its election to adjust the number of Rights, indicating the record date for the adjustment to be made with prompt notice thereof to the Rights Agent. This record date may be the date on which the Purchase Price is adjusted or any day thereafter, but, if the Rights Certificates have been issued, shall be at least ten (10) days later than the date of the public announcement. If Rights Certificates have been issued, upon each adjustment of the number of Rights pursuant to this Section 11(i), the Company shall, as promptly as practicable, cause to be distributed to holders of record of Rights Certificates on such record date Rights Certificates evidencing, subject to Section 14 hereof, the additional Rights to which such holders shall be entitled as a result of such adjustment, or, at the option of the Company, shall cause to be distributed to such holders of record in substitution and replacement for the Rights Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Company, new Rights Certificates evidencing all the Rights to which such holders shall be entitled after such adjustment. Rights Certificates so to be distributed shall be issued executed and countersigned in the manner provided for herein (and may bear, at the option of the Company, the adjusted Purchase Price) and shall be registered in the names of the holders of record of Rights Certificates on the record date specified in the public announcement. (j) Irrespective of any adjustment or change in the Purchase Price or the number of one one-hundredth of a share of Preferred Stock issuable upon the exercise of the Rights, the Rights Certificates theretofore and thereafter issued may continue to express the Purchase Price per one one-hundredth of a share and the number of one one-hundredth of a share which were expressed in the initial Rights Certificates issued hereunder. (k) Before taking any action that would cause adjustment reducing the Purchase Price below the then stated value, if any, of the number of one one-hundredth of a share of Preferred Stock issuable upon exercise of the Rights, the Company shall take any corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue fully paid and nonassessable such number of one one-hundredth of a share of Preferred Stock at such adjusted Purchase Price. (l) In any case in which this Section 11 shall require that an adjustment in the Purchase Price be made effective as of a record date for a specified event, the Company may elect to defer with prompt notice thereof to the Rights Agent until the occurrence of such event the issuance to the holder of any Right exercised after such record date the number of one one-hundredth of a share of Preferred Stock and other 22

23 capital stock or securities of the Company, if any, issuable upon such exercise over and above the number of one one-hundredth of a share of Preferred Stock and other capital stock or securities of the Company, if any, issuable upon such exercise on the basis of the Purchase Price in effect prior to such adjustment; provided, however, that the Company shall deliver to such holder a due bill or other appropriate instrument evidencing such holder's right to receive such additional shares (fractional or otherwise) or securities upon the occurrence of the event requiring such adjustment. (m) Anything in this Section 11 to the contrary notwithstanding, the Company shall be entitled to make such reductions in the Purchase Price, in addition to those adjustments expressly required by this Section 11, as and to the extent that in their good faith judgment the Board of Directors of the Company shall determine to be advisable in order that any (i) consolidation or subdivision of the Preferred Stock, (ii) issuance wholly for cash or any shares of Preferred Stock at less than the current market price, (iii) issuance wholly for cash or shares of Preferred Stock or securities which by their terms are convertible into or exchangeable for shares of Preferred Stock, (iv) stock dividends or (v) issuance of rights, options or warrants referred to in this Section 11, hereafter made by the Company to holders of its Preferred Stock shall not be taxable to such stockholders. (n) The Company covenants and agrees that it shall not, at any time after the Distribution Date, (i) consolidate with any other Person (other than a Subsidiary of the Company in a transaction which complies with Section 11(o) hereof), (ii) merge with or into any other Person (other than a Subsidiary of the Company in a transaction which complies with Section 11(o) hereof), or (iii) sell or transfer (or permit any Subsidiary to sell or transfer), in one transaction, or a series of related transactions, assets or earning power aggregating more than 50% of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to any other Person or Persons (other than the Company and/or any of its Subsidiaries in one or more transactions each of which complies with Section 11(o) hereof), if (x) at the time of or immediately after such consolidation, merger, sale or transfer there are any rights, warrants or other instruments or securities outstanding or agreements in effect which would substantially diminish or otherwise eliminate the benefits intended to be afforded by the Rights or (y) prior to, simultaneously with or immediately after such consolidation, merger, sale or transfer, the shareholders of the Person who constitutes, or would constitute, the "Principal Party" for purposes of Section 13(a) hereof shall have received a distribution of Rights previously owned by such Person or any of its Affiliates and Associates. (o) The Company covenants and agrees that, after the Distribution Date, it will not, except as permitted by Section 23 or Section 27 hereof, take (or permit any Subsidiary to take) any action if at the time such action is taken it is reasonably 23

24 foreseeable that such action will diminish substantially or otherwise eliminate the benefits intended to be afforded by the Rights. (p) Anything in this Agreement to the contrary notwithstanding, in the event that the Company shall at any time after the Rights Dividend Declaration Date and prior to the Distribution Date (i) declare a dividend on the outstanding shares of Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding shares of Common Stock, or (iii) combine the outstanding shares of Common Stock into a smaller number of shares, the number of Rights associated with each share of Common Stock then outstanding, or issued or delivered thereafter but prior to the Distribution Date, shall be proportionately adjusted so that the number of Rights thereafter associated with each share of Common Stock following any such event shall equal the result obtained by multiplying the number of Rights associated with each share of Common Stock immediately prior to such event by a fraction the numerator which shall be the total number of shares of Common Stock outstanding immediately prior to the occurrence of the event and the denominator of which shall be the total number of shares of Common Stock outstanding immediately following the occurrence of such event. Section 12. Certificate of Adjusted Purchase Price or Number of Shares. Whenever an adjustment is made as provided in Section 11 and Section 13 hereof, the Company shall (a) promptly prepare a certificate setting forth such adjustment and a brief statement of the facts and computations accounting for such adjustment, (b) promptly file with the Rights Agent, and with each transfer agent for the Preferred Stock and the Common Stock, a copy of such certificate, and (c) mail a brief summary thereof to each holder of a Rights Certificate (or, if prior to the Distribution Date, to each holder of a certificate representing shares of Common Stock) in accordance with Section 26 hereof. Notwithstanding the foregoing sentence, the failure of the Company to give such notice shall not affect the validity of or the force or effect of or the requirement for such adjustment. The Rights Agent shall be fully protected in relying on any such certificate and on any adjustment therein contained. Any adjustment to be made pursuant to Sections 11 and 13 of this Agreement shall be effective as of the date of the event giving rise to such adjustment; provided, however, that the Rights Agent shall have no duty with respect to and shall not be deemed to have any knowledge of any such adjustment unless and until it shall have received such certificate. Section 13. Consolidation. Merger or Sale or Transfer of Assets or Earning Power. (a) In the event that, following the Stock Acquisition Date, directly or indirectly, (x) the Company shall consolidate with, or merge with and into, any other Person (other than a Subsidiary of the Company in a transaction which complies with 24

25 Section 11(o) hereof), and the Company shall not be the continuing or surviving corporation of such consolidation or merger, (y) any Person (other than a Subsidiary of the Company in a transaction which complies with Section 11(o) hereof) shall consolidate with, or merge with or into, the Company, and the Company shall be the continuing or surviving corporation of such consolidation or merger, and, in connection with such consolidation or merger, all or part of the outstanding shares of Common Stock shall be changed into or exchanged for stock or other securities of any other Person or cash or any other property, or (z) the Company shall sell or otherwise transfer (or one or more of its Subsidiaries shall sell or otherwise transfer), in one transaction or a series of related transactions, assets or earning power aggregating more than 50% of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to any Person or Persons (other than the Company or any Subsidiary of the Company in one or more transactions each of which complies with Section 11(o) hereof), then, and in each such case, proper provisions shall be made so that: (i) each holder of a Right, except as provided in Section 7(e) hereof, shall thereafter have the right to receive, upon the exercise thereof at the then current Purchase Price in accordance with the terms of this Agreement, such number of validly authorized and issued, fully paid, non-assessable and freely tradeable shares of Common Stock of the Principal Party (as such term is hereinafter defined), not subject to any liens, encumbrances, rights of first refusal or other adverse claims, as shall be equal to the result obtained by (1) multiplying the then current Purchase Price by the number of one one-hundredth of a share of Preferred Stock for which a Right was exercisable immediately prior to the occurrence of a Section 11(a)(ii) Event by the Purchase Price in effect immediately prior to such Section 11(a)(ii) Event, and (2) dividing that product (which, following the first occurrence of a Section 13 Event, shall be referred to as the "Purchase Price" for each Right and for all purposes of this Agreement) by 50% of the current market price (determined pursuant to Section 11(d)(i) hereof) per share of the Common Stock of such Principal Party on the date of consummation of such Section 13 Event (or the fair market value on such date of other securities or property of the Principal Party, as provided for herein); provided that the Purchase Price and the number of shares of Common Stock of such Principal Party issuable upon exercise of each Right shall be further adjusted as provided in this Agreement to reflect any events occurring after the date of the first occurrence of a Section 13 event; (ii) such Principal Party shall thereafter be liable for, and shall assume, by virtue of such Section 13 Event, all the obligations and duties of the Company pursuant to this Agreement; (iii) the term "Company" shall thereafter be deemed to refer to such Principal Party, it being specifically intended that the provisions of Section 11 hereof shall apply only to such Principal Party following the first occurrence of a Section 13 Event; (iv) such Principal Party shall take such steps (including, but not limited to, the reservation of a sufficient number of shares of its Common Stock) in connection with the consummation of any such transaction as may be necessary to assure that the provisions hereof shall thereafter be applicable, as nearly as reasonably may be, in relation to its shares of Common Stock thereafter 25

26 deliverable upon the exercise of the Rights; provided, however, that upon the subsequent occurrence of any merger, consolidation, sale of all or substantially all assets, recapitalization, reclassification of shares, reorganization or other extraordinary transaction in respect of such Principal Party, each holder of a Right shall thereupon be entitled to receive, upon exercise of a Right and payment of the Purchase Price, such cash, shares, rights, warrants and other property which such holder would have been entitled to receive had he, at the time of such transaction, owned the shares of Common Stock of the Principal Party purchasable upon the exercise of a Right, and such Principal Party shall take such steps (including, but not limited to, reservation of shares of stock) as may be necessary to permit the subsequent exercise of the Rights in accordance with the terms hereof for such cash, shares, rights, warrants and other property; and (v) the provisions of Section 11(a)(ii) hereof shall be of no effect following the first occurrence of any Section 13 Event. (b) "Principal Party" shall mean: (i) the case of any transaction described in clause (x) or (y) of the first sentence of Section 13(a): (A) the Person that is the issuer of any securities into which shares of Common Stock of the Company are converted in such merger or consolidation, or, if there is more than one such issuer, the issuer whose Common Stock has the greatest market value or (B) if no securities are so issued, (x) the Person that is the other party to such merger or consolidation and survives said merger or consolidation, or, if there is more than one such Person, the Person whose Common Stock has the greatest market value or (y) if the Person that is the other party to the merger or consolidation does not survive the merger or consolidation, the Person that does survive the merger or consolidation (including the Company if it survives); and (ii) in the case of any transaction described in clause (z) of the first sentence of Section 13(a), the Person that is the party receiving the greatest portion of the assets or earning power transferred pursuant to such transaction or transactions, or, if each Person that is a party to such transaction or transactions receives the same portion of the assets or earning power so transferred or if the Person receiving the greatest portion of the assets or earning power cannot be determined, whichever of such Persons as is the issuer of Common Stock having the greatest market value of shares outstanding; provided, however, that in any such case, (1) if the Common Stock of such Person is not at such time and has not been continuously over the preceding twelve (12) month period registered under Section 12 of the Exchange Act, and such Person is a direct or indirect subsidiary of another Person the Common Stock of which is and has been so registered, "Principal Party" shall refer to such other Person; and (2) if such Person is a Subsidiary, directly or indirectly, of more than one Person, the Common Stocks of two or more of which are and have been so registered, "Principal Party" shall refer to whichever of such persons is the issuer of the Common Stock having the greatest aggregate market value. 26

27 (c) The Company shall not consummate any such consolidation, merger, sale or transfer unless the Principal Party shall have a sufficient number of authorized shares of its Common Stock which have not been issued or reserved for issuance to permit the exercise in full of the Rights in accordance with this Section 13 and unless prior thereto the Company and such Principal Party shall have executed and delivered to the Rights Agent a supplemental agreement providing for the terms set forth in paragraphs (a) and (b) of this Section 13 and further providing that, as soon as practicable after the date of any consolidation, merger, sale or transfer mentioned in paragraph (a) of this Section 13, the Principal Party will: (i) prepare and file a registration statement under the Act, with respect to the Rights and the securities purchasable upon exercise of the Rights on an appropriate form, and will use its best efforts to cause such registration statement to (A) become effective as soon as practicable after such filing and (B) remain effective (with a prospectus at all times meeting the requirements of the Act) until the Expiration Date and similarly comply with applicable state securities laws; (ii) will deliver to holders of the Rights historical financial statements of the Principal Party and each of its Affiliates which comply in all respects with the requirements for registration on Form 10 (or any successor form) under the Exchange Act; (iii) use its best efforts, if the Common Stock of the Principal Party shall become listed on a national securities exchange, to list (or continue the listing of) the Rights and the securities purchasable upon exercise of the Rights on such securities exchange and, if the Common Stock of the Principal Party shall not be listed on a national securities exchange, to cause the Rights and the securities purchasable upon exercise of the Rights to be reported by NASDAQ or such other system then in use; and (iv) obtain waivers of any rights of first refusal or preemptive rights in respect of the shares of Common Stock of the Principal Party subject to purchase upon exercise of outstanding Rights. The provisions of this Section 13 shall similarly apply to successive mergers or consolidations or sales or transfers. In the event that a Section 13 Event shall occur at any time after the occurrence of a Section 11(a)(ii) Event, the Rights which have not theretofore been exercised shall thereafter become exercisable in the manner described in Section 13(a). (d) Notwithstanding anything in this Agreement to the contrary, Section 13 shall not be applicable to a transaction described in subparagraphs (x) and (y) of Section 13(a) if (i) such transaction is consummated with a Person or Persons who acquired shares of Common Stock pursuant to a tender offer or exchange offer for all 27

28 outstanding shares of Common Stock which complies with the provisions of Section 11(a)(ii) hereof (or a wholly owned subsidiary of any such Person or Persons), (ii) the price per share of Common Stock offered in such transaction is not less than the price per share of Common Stock paid to all holders of shares of Common Stock whose shares were purchased pursuant to such tender offer or exchange offer, and (iii) the form of consideration being offered to the remaining holders of shares of Common Stock pursuant to such transaction is the same as the form of consideration paid pursuant to such tender offer or exchange offer. Upon consummation of any such transaction contemplated by this Section 13(d), all Rights under this Agreement shall expire, and this Agreement shall terminate. Section 14. Fractional Rights and Fractional Shares. (a) The Company shall not be required to issue fractions of Rights, except prior to the Distribution Date as provided in Section 11(p) hereof, or to distribute Rights Certificates which evidence fractional Rights. In lieu of such fractional Rights, there shall be paid to the registered holders of the Rights Certificates with regard to which such fractional Rights would otherwise be issuable, an amount in cash equal to the same fraction of the current market value of a whole Right. For purposes of this Section 14(a), the current market value of a whole Right shall be the closing price of the Rights for the Trading Day immediately prior to the date on which such fractional Rights would have been otherwise issuable. The closing price of the Rights for any day shall be the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the Rights are not listed or admitted to trading on the New York Stock Exchange, as reported in the principal consolidated transaction reporting system with respect to securities listed on the principal national securities exchange on which the Rights are listed or admitted to trading, or if the Rights are not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by NASDAQ or such other system then in use or, if on any such date the Rights are not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Rights selected by the Board of Directors of the Company. If on any such date no such market maker is making a market in the Rights the fair value of the Rights on such date as determined in good faith by the Board of Directors of the Company shall be used. (b) The Company shall not be required to issue fractions of shares of Preferred Stock (other than fractions which are integral multiples of one one one-hundredth of a share of Preferred Stock) upon exercise of the Rights or to distribute certificates which evidence fractional shares of Preferred Stock (other than 28

29 fractions which are integral multiples of one one-hundredth of a share of Preferred Stock). In lieu of fractional shares of Preferred Stock that are not integral multiples of one one-hundredth of a share of Preferred Stock, the Company may pay to the registered holders of Rights Certificates at the time such Rights are exercised as herein provided an amount in cash equal to the same fraction of the current market value of one one-hundredth of a share of Preferred Stock. For purposes of this Section 14(b), the current market value of one one-hundredth of a share of Preferred Stock shall be one one-hundredth of the closing price of a share of Preferred Stock (as determined pursuant to Section 11(d)(ii) hereof) for the Trading Day immediately prior to the date of such exercise. (c) Following the occurrence of a Triggering Event, the Company shall not be required to issue fractions of shares of Common Stock upon exercise of the Rights or to distribute certificates which evidence fractional shares of Common Stock. In lieu of fractional shares of Common Stock, the Company may pay to the registered holders of Rights Certificates at the time such Rights are exercised as herein provided an amount in cash equal to the same fraction of the current market value of one (1) share of Common Stock. For purposes of this Section 14(c), the current market value of one share of Common Stock shall be the closing price of one share of Common Stock (as determined pursuant to Section 11(d)(i) hereof) for the Trading Day immediately prior to the date of such exercise. (d) The holder of a Right by the acceptance of the Rights expressly waives his right to receive any fractional Rights or any fractional shares upon exercise of a Right, except as permitted by this Section 14. Section 15. Rights of Action. All rights of action in respect of this Agreement, other than rights of action vested in the Rights Agent pursuant to this Agreement, are vested in the respective registered holders of the Rights Certificates (and, prior to the Distribution Date, the registered holders of the Common Stock); and any registered holder of any Rights Certificate (or, prior to the Distribution Date, of the Common Stock), without the consent of the Rights Agent or of the holder of any other Rights Certificate (or, prior to the Distribution Date, of the Common Stock) may, in his own behalf and for his own benefit, enforce, and may institute and maintain any suit, action or proceeding against the Company to enforce, or otherwise act in respect of, his right to exercise the Rights evidenced by such Rights Certificate in the manner provided in such Rights Certificate and in this Agreement. Without limiting the foregoing or any remedies available to the holders of Rights, it is specifically acknowledged that the holders of Rights would not have an adequate remedy at law for any breach of this Agreement and shall be entitled to specific performance of the obligations hereunder and injunctive relief against actual or threatened violations of the obligations hereunder of any Person subject to this Agreement. 29

30 Section 16. Agreement of Rights Holders. Every holder of a Right by accepting the same consents and agrees with the Company and the Rights Agent and with every other holder of a Right that: (a) Prior to the Distribution Date, the Rights will be transferable only in connection with the transfer of Common Stock; (b) After the Distribution Date, the Rights Certificates are transferable only on the registry books of the Rights Agent if surrendered at the office or offices of the Rights Agent designated for such purposes, duly endorsed or accompanied by a proper instrument of transfer and with the appropriate forms and certificates fully executed; (c) The Company and the Rights Agent may deem and treat the person in whose name a Rights Certificate (or, prior to the Distribution Date, the associated Common Stock certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of ownership or writing on the Rights Certificates or the associated Common Stock certificate made by anyone other than the Company or the Rights Agents) for all purposes whatsoever, and neither the Company nor the Rights Agent shall be required to be affected by any notice to the contrary; and (d) Notwithstanding anything in this Agreement to the contrary, neither the Company nor the Rights Agent shall have any liability to any holder of a Right or other Person as a result of its inability to perform any of its obligations under this Agreement by reason of any preliminary or permanent injunction or other order decree or ruling issued by a court of competent jurisdiction or by a governmental, regulatory or administrative agency or commission, or any statute, rule, regulation or executive order promulgated or enacted by any governmental authority, prohibiting or otherwise restraining performance of such obligation; provided, however, the Company must use its best efforts to have any such order, decree or ruling lifted or otherwise overturned as soon as possible. Section 17. Rights Certificate Holder Not Deemed a Stockholder. No holder, as such, of any Rights Certificate shall be entitled to vote, receive dividends or be deemed for any purposes the holder of the number of one one-hundredth of a share of Preferred Stock or any other securities of the Company which may at any time be issuable on the exercise of the Rights represented thereby, nor shall anything contained herein or in any Rights Certificate be construed to confer upon the holder of any Rights Certificate, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting stockholders (except as provided in Section 24 hereof), or to receive dividends or subscription rights, or otherwise, until the Right or 30

31 Rights evidenced by such Rights Certificate shall have been exercised in accordance with the provisions hereof. Section 18. Concerning the Rights Agent. (a The Company agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and disbursements and other disbursements incurred in the administration, preparation, delivery, amendment and execution of this Agreement and the exercise and performance of its duties hereunder. The Company also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability, damage, judgment, fine, penalty, claim, demand, settlement cost or expense, incurred without negligence, bad faith or willful misconduct, as determined by a court of competent jurisdiction, on the part of the Rights Agent, for any action taken, suffered or omitted by the Rights Agent in connection with the acceptance, amendment and administration of this Agreement, including, without limitation, the costs and expenses of defending against any claim of liability arising therefrom, directly or indirectly. The indemnity provided herein shall survive the termination of this Agreement and the termination and the expiration of the Rights. The costs and expenses incurred in enforcing this right of indemnification shall be paid by the Company. Anything to the contrary notwithstanding, in no event shall the Rights Agent be liable for special, punitive, indirect, consequential or incidental loss or damage of any kind whatsoever (including, but not limited to, lost profits), even if the Rights Agent has been advised of the likelihood of such loss or damage. (b The Rights Agent shall be authorized and protected and shall incur no liability for or in respect of any action taken, suffered or omitted by it in connection with its administration of this Agreement in reliance upon any Rights Certificate or certificate for Common Stock or for other securities of the Company, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, statement, or other paper or document believed by it to be genuine and to be signed, executed and, where necessary, verified or acknowledged, by the proper Person or Persons or otherwise upon the advice of counsel as set forth in Section 20. Section 19. Merger or Consolidation or Change of Name of Rights Agent. (a) Any Person into which the Rights Agent or any successor Rights Agent may be merged or with which it may be consolidated, or any Person resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any Person succeeding to the shareholder services business of the Rights Agent or any successor Rights Agent, shall be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act, on the 31

32 part of any of the parties hereto; provided, however, that such Person would be eligible for appointment as a successor Rights Agent under the provisions of Section 21 hereof. In case at the time such successor Rights Agent shall succeed to the agency created by this Agreement, any of the Rights Certificates shall have been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of a predecessor Rights Agent and deliver such Rights Certificates so countersigned; and in case at that time any of the Rights Certificates shall not have been countersigned, any successor Rights Agent may countersign such Rights Certificates either in the name of the predecessor or in the name of the successor Rights agent; and in all such cases such Rights Certificates shall have the full force provided in the Rights Certificates and in this Agreement. (b) In case at any time the name of the Rights Agent shall be changed and at such time any of the Rights Certificates shall have been countersigned but not delivered, the Rights Agent may adopt the countersignature under its prior name and deliver Rights Certificates so countersigned; and in case at that time any of the Rights Certificates shall not have been countersigned, the Rights Agent may countersign such Rights Certificates either in its prior name or in its changed name; and in all such cases such Rights Certificates shall have the full force provided in the Rights Certificates and in this Agreement. Section 20. Duties of Rights Agent. The Rights Agent undertakes only the duties and obligations expressly imposed by this Agreement upon the following terms and conditions, by all of which the Company and the holders of Rights Certificates, by their acceptance thereof, shall be bound: (a) The Rights Agent may consult with legal counsel (who may be legal counsel for the Company), and the advice or opinion of such counsel shall be full and complete authorization and protection to the Rights Agent as to any action taken, suffered or omitted by it in good faith and in accordance with such advice or opinion. (b) Whenever in the performance of its duties under this Agreement the Rights Agent shall deem it necessary or desirable that any fact or matter (including, without limitation, the identity of any Acquiring Person and the determination of "current market price") be proved or established by the Company prior to taking, omitting or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed by the Chairman of the Board, the President, any Vice President, the Treasurer, any Assistant Treasurer, the Secretary or any Assistant Secretary of the Company and delivered to the Rights Agent; and such certificate shall be full authorization and protection to the Rights Agent and the Rights Agent shall incur no liability for or in respect of any action taken, suffered or omitted 32

33 in good faith by it under the provisions of this Agreement in reliance upon such certificate. (c) The Rights Agent shall not be liable for or by reason of the statements of fact or recitals contained in this Agreement or in the Rights Certificates or be required to verify the same (except as to its countersignature on such Rights Certificates), but all such statements and recitals are and shall be deemed to have been made by the Company only. (d) The Rights Agent shall not be under any liability or responsibility in respect of the validity of this Agreement or the execution and delivery hereof (except the due execution hereof by the Rights Agent) or in respect of the validity or execution of any Rights Certificate (except its countersignature thereof), nor shall it be responsible or liable for any adjustment required under this Agreement or responsible for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment (except with respect to the exercise of Rights evidenced by Rights Certificates after receipt of the certificate described in Section 12 hereof setting forth any such adjustment); nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Common Stock or Preferred Stock to be issued pursuant to this Agreement or any Rights Certificates or as to whether any shares of Common Stock or Preferred Stock will, when so issued, be validly authorized and issued, fully paid and nonassessable. (e) The Company agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Rights Agent for the carrying out or performing by the Rights Agent of the provisions of this Agreement. (f) The Rights Agent is hereby authorized and directed to accept instructions with respect to the performance of its duties hereunder from the Chairman of the Board, the President, any Vice President, the Secretary, any Assistant Secretary, the Treasurer or any Assistant Treasurer of the Company, and to apply to such officers for advice or instructions in connection with its duties, and it shall not be liable for any action taken, suffered or omitted to be taken by it in good faith in accordance with instructions of any such officer or for any delay in acting while waiting for those instructions. Any application by the Rights Agent for written instructions from the Company may, at the option of the Rights Agent, set forth in writing any action proposed to be taken, suffered or omitted by the Rights Agent under this Agreement and the date on and/or after which such action shall be taken or suffered or such omission shall be effective. The Rights Agent shall not be liable for any action taken or suffered by, or omission of, the Rights Agent in accordance with a proposal included 33

34 in any such application on or after the date specified in such application (which date shall not be less than five (5) Business Days after the date any officer of the Company actually receives such application unless any such officer shall have consented in writing to an earlier date) unless, prior to taking any such action (or the effective date in the case of an omission), the Rights Agent shall have received written instructions in response to such application specifying the action to be taken, suffered or omitted. (g) The Rights Agent and any stockholder, director, Affiliate, officer or employee of the Rights Agent may buy, sell or deal in any of the Rights or other securities of the Company or become pecuniarily interested in any transaction in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it were not Rights Agent under this Agreement. Nothing herein shall preclude the Rights Agent from acting in any other capacity for the Company or for any other Person. (h) The Rights Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorneys or agents, and the Rights Agent shall not be answerable or accountable for any act, default, neglect or misconduct or any such attorneys or agents or for any loss to the Company resulting from any such act, default, neglect or misconduct absent negligence, bad faith or willful misconduct, as determined by a court of competent jurisdiction; provided, however, reasonable care was exercised in the selection and continued employment thereof. (i) No provision of this Agreement shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of its rights if there shall be reasonable grounds for believing that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it. (j) If, with respect to any Rights Certificate surrendered to the Rights Agent for exercise or transfer, the certificate attached to the form of assignment or form of election to purchase as the case may be, has either not been completed or indicates an affirmative response to clause 1 and/or 2 thereof, the Rights Agent shall not take any further action with respect to such requested exercise of transfer without first consulting with the Company. Section 21. Change of Rights Agent. The Rights Agent or any successor Rights Agent may resign (with or without cause) and be discharged from its duties under this Agreement upon thirty (30) days' notice in writing mailed to the Company, and to each transfer agent of the Common Stock and Preferred Stock by registered or certified mail, and to the holders of the Rights Certificates by first-class mail. The Company may remove the Rights Agent or any successor Rights Agent (with or without cause) 34

35 upon thirty (30) days' notice in writing, mailed to the Rights Agent or successor Rights Agent, as the case may be, and to each transfer agent of the Common Stock and Preferred Stock, by registered or certified mail, and to the holders of the Rights Certificates by first-class mail. If the Rights Agent shall resign or be removed or shall otherwise become incapable of acting, the Company shall appoint a successor to the Rights Agent. If the Company shall fail to make such appointment within a period of thirty (30) days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent or by the holder of a Rights Certificate (who shall, with such notice, submit his Rights Certificate for inspection by the Company), then the incumbent Rights Agent or any registered holder of any Rights Certificate may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Company or by such a court, shall be (a) organized and doing business under the laws of the United States or of any other state of the United States in good standing, which is authorized under such laws and is subject to supervision or examination by federal or state authority and which has at the time of its appointment as Rights Agent a combined capital and surplus of at least $50,000,000 or (b) an Affiliate of such a Person described in clause (a) of this sentence. After appointment, the successor Rights Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed; but the predecessor Rights Agent shall deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Company shall file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Stock and the Preferred Stock, and mail a notice thereof in writing to the registered holders of the Rights Certificates. Failure to give any notice provided for in this Section 21, however, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of the successor Rights Agent, as the case may be. Section 22. Issuance of New Rights Certificates. Notwithstanding any of the provisions of this Agreement or of the Rights to the contrary, the Company may, at its option, issue new Rights Certificates evidencing Rights in such form as may be approved by its Board of Directors to reflect any adjustment or change in the Purchase Price and the number or kind or class of shares or other securities or property purchasable under the Rights Certificates made in accordance with the provisions of this Agreement. In addition, in connection with the issuance or sale of shares of Common Stock following the Distribution Date and prior to the redemption or expiration of the Rights, the Company (a) shall, with respect to shares of Common Stock so issued or sold pursuant to the exercise of stock options or under any employee plan or arrangement, or upon the exercise, conversion or exchange of securities hereinafter issued by the Company, and (b) may, in any other case, if deemed 35

36 necessary or appropriate by the Board of Directors of the Company, issue Rights Certificates representing the appropriate number of Rights in connection with such issuance or sale; provided, however, that (i) no such Rights Certificate shall be issued if, and to the extent that, the Company shall be advised by counsel that such issuance would create a significant risk of material adverse tax consequences to the Company or the Person to whom such Rights Certificate would be issued, and (ii) no such Rights Certificate shall be issued if, and to the extent that, appropriate adjustment shall otherwise have been made in lieu of the issuance thereof. Section 23. Redemption and Termination. (a) (i) The Board of Directors of the Company may, at its option, at any time prior to the earlier of (x) the Close of Business on the tenth day following the Stock Acquisition Date (or, if the Stock Acquisition Date shall have occurred prior to the Record Date, the Close of Business on the tenth day following the Record Date), subject to extension by the Board of Directors by amendment as in Section 27 hereof or (y) the Close of Business on the Final Expiration Date, redeem all but not less than all the then outstanding Rights at a redemption price of $0.01 per Right, as such amount may be appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date hereof (such redemption price being hereinafter referred to as the "Redemption Price"). Notwithstanding anything contained in this Agreement to the contrary, the Rights shall not be exercisable after the occurrence of an event described in Section 11(a)(ii) until such time as the Company's right of redemption hereunder has expired. The Company may, at its option, pay the Redemption Price in cash, shares of Common Stock (based on the "current market price", as defined in Section 11(d)(i) hereof, of the Common Stock at the time of redemption) or any other form of consideration deemed appropriate by the Board of Directors. (ii) In addition, the Company's right of redemption shall be reinstated and the Company may, at its option, after the Distribution Date, but prior to any event described in Section 13(a) either (x) in connection with any event described in Section 13(a) in which all holders are treated alike and not involving (other than as a holder of Common Stock being treated like all other such holders) an Acquiring Person or an Affiliate or Associate of an Acquiring Person or any other Person acting directly or indirectly on behalf of or in association with any such Acquiring Person, Affiliate or Associate, or (y) following the occurrence of an event set forth in Section 11(a)(ii), if and for as long as the Acquiring Person is not thereafter the Beneficial Owner of securities representing 10% or more of the then outstanding shares of Common Stock, and at the time of redemption there are no other persons who are Acquiring Persons. (b) In the case of a redemption permitted by Section 23(a)(i), immediately upon the action of the Board of Directors of the Company ordering the redemption of 36

37 the Rights, and without any further action and without any notice, the right to exercise the Rights will terminate and the only right thereafter of the holders of Rights shall be to receive the Redemption Price for each Right so held, without any interest thereon. In the case of a redemption permitted only under Section 23(a)(ii), the right to exercise the Rights will terminate and represent only the right to receive the Redemption Price only after ten Business Days following the giving of notice of such redemption to the Rights Agent and to the holders of such Rights if no event set forth in Section 11(a)(ii) shall have occurred, and if such event shall have occurred, only at such date as may be determined by the Board of Directors. Promptly after the action of the Board of Directors ordering the redemption of the Rights, the Company shall give notice of such redemption to the Rights Agent and the holders of the then outstanding Rights by mailing such notice to all such holders at each holder's last address as it appears upon the registry books of the Rights Agent or, prior to the Distribution Date, on the registry books of the Transfer Agent for the Common Stock. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of redemption will state the method by which the payment of the Redemption Price will be made. The failure to give notice required by this Section 23(b) or any defect therein shall not affect the legality or validity of the action taken by the Company. Section 24. Exchange. (a) The Board of Directors of the Company may, at its option, at any time and from time to time after the first occurrence of a Section 11(a)(ii) Event, exchange all or part of the then outstanding and exercisable Rights (which shall not include Rights that have become void pursuant to the provisions of Section 7(e) hereof) for shares of Common Stock or Common Stock Equivalents or any combination thereof, at an exchange ratio of one share of Common Stock, or such number of Common Stock Equivalents or units representing fractions thereof as would be deemed to have the same value as one share of Common Stock, per Right, appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the Rights Dividend Declaration Date (such exchange ratio being hereinafter referred to as the "Exchange Ratio"). Any decision to exchange all or part of the then outstanding and exercisable Rights in the fourteen (14) day period after the occurrence of a Section 11(a)(ii) Event shall be superior to and preempt any attempted exercise by a holder under Section 11(a)(ii). (b) Immediately upon the action of the Board of Directors of the Company ordering the exchange of any Rights pursuant to subsection (a) of this Section 24 and without any further action and without any notice, the right to exercise such Rights shall terminate and the only right thereafter of the holders of such Rights shall be to receive that number of shares of Common Stock and/or Common Stock Equivalents equal to the number of such Rights held by such holder multiplied by the Exchange 37

38 Ratio. The Company shall promptly give public notice of any such exchange with prompt notice thereof to the Rights Agent; provided, however, that the failure to give, or any defect in, such notice shall not affect the validity of such exchange. The Company promptly shall mail a notice of any such exchange to all of the holders of such Rights at their last addresses as they appear upon the registry books of the Rights Agent. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of exchange will state the method by which the exchange of the shares of Common Stock and/or Common Stock Equivalents for Rights will be effected and, in the event of any partial exchange, the number of Rights that will be exchanged. Any partial exchange shall be effected pro rata based on the number of Rights (other than Rights which have become null and void pursuant to the provisions of Section 7(e) hereof) held by each holder of Rights. (c) In the event that the number of shares of Common Stock that are authorized by the Company's certificate of incorporation but not outstanding or reserved for issuance for purposes other than upon exercise of the Rights is not sufficient to permit an exchange of Rights as contemplated in accordance with this Section 24, the Company may, at its option, take all such action as may be necessary to authorize additional shares of Common Stock for issuance upon exchange of the Rights. (d) The Company shall not be required to issue fractions of shares of Common Stock or to distribute certificates or scrip evidencing fractional shares of Common Stock. In lieu of such fractional shares of Common Stock, the Company shall pay to the registered holders of Rights with regard to which such fractional shares of Common Stock would otherwise be issuable an amount in cash equal to the same fraction of the value of a whole share of Common Stock. For purposes of this Section 24, the value of a whole share of Common Stock shall be the closing price (as determined pursuant to the second sentence of Section 11(d)(i) hereof) for the Trading Day immediately prior to the date of exchange pursuant to this Section 24, and the value of any Common Stock Equivalent shall be deemed to have the same value as the Common Stock on such date. Section 25. Notice of Certain Events. (a) In case the Company shall propose, at any time after the Distribution Date, (i) to pay any dividend payable in stock of any class to the holders of Preferred Stock or to make any other distribution to the holders of Preferred Stock (other than a regular quarterly cash dividend out of earnings or retained earnings of the Company), or (ii) to offer to the holders of Preferred Stock rights or warrants to subscribe for or to purchase any additional shares of Preferred Stock or shares of stock of any class or any other securities, rights or options, or (iii) to effect any 38

39 reclassification of its Preferred Stock (other than a reclassification involving only the subdivision of outstanding shares of Preferred Stock), or (iv) to effect any consolidation or merger into or with any other Person (other than a Subsidiary of the Company in a transaction which complies with Section 11(o) hereof), or to effect any sale or other transfer (or to permit one or more of its Subsidiaries to effect any sale or other transfer), in one transaction or a series of related transactions, of more than 50% of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to any other Person or Persons (other than the Company and/or any of its Subsidiaries in one or more transactions each of which complies with Section 11(o) hereof), or (v) to effect the liquidation, dissolution or winding up of the Company, then, in each such case, the Company shall give to each holder of a Rights Certificate and the Rights Agent, to the extent feasible and in accordance with Section 26 hereof, a notice of such proposed action, which shall specify the record date for the purposes of such stock dividend, distribution of rights or warrants, or the date on which such reclassification, consolidation, merger, sale, transfer, liquidation, dissolution, or winding up is to take place and the date of participation therein by the holders of the shares of Preferred Stock, if any such date is to be fixed, and such notice shall be so given in the case of any action covered by clause (i) or (ii) above at least ten (10) days prior to the record date for determining holders of the shares of Preferred Stock for purposes of such action, and in the case of any such other action, at least ten (10) days prior to the date of the taking of such proposed action or the date of participation therein by the holders of the shares of Preferred Stock whichever shall be the earlier. The failure to give notice required by this Section 25 or any defect therein shall not affect the legality or validity of the action taken by the Company or the vote upon any such action. (b) In case any of the events set forth in Section 11(a)(ii) hereof shall occur, then, in any such case, (i) the Company shall as soon as practicable thereafter give to each holder of a Rights Certificate and the Rights Agent, to the extent feasible and in accordance with Section 26 hereof, a notice of the occurrence of such event, which shall specify the event and the consequences of the event to holders of Rights under Section 11(a)(ii) hereof, and (ii) all references in the preceding paragraph to Preferred Stock shall be deemed thereafter to refer to Common Stock and/or, if appropriate, other securities. Section 26. Notices. Notices or demands authorized by this Agreement to be given or made by the Rights Agent or by the holder of any Rights Certificate to or on the Company shall be sufficiently given or made if sent by first-class mail, postage prepaid, addressed (until another address is filed in writing with the Rights Agent) as follows: 39

Section 27. Supplements and Amendments. Prior to the Distribution Date (which date is subject to extension by the Board of Directors by amendment), and subject to the penultimate sentence of this Section 27, the Company may, in its sole and absolute discretion and the Rights Agent shall, if the Company so directs, supplement or amend any provision of this Agreement without the approval of any holders of certificates representing shares of Common Stock, whether or not such supplement or amendment is adverse to any holders of Rights. From and after the Distribution Date, and subject to the penultimate sentence of this Section 27, the Company may and the Rights Agent shall, if the Company so directs, supplement or amend this Agreement without the approval of any holders of Rights Certificates in order (i) to cure any ambiguity, (ii) to correct or supplement any provision contained herein which may be defective or inconsistent with any other provisions hereunder or (iii) to change or supplement the provisions hereunder in any manner which the Company may deem necessary or desirable and which shall not materially and adversely affect the interests of the holders of Rights Certificates (other than an Acquiring Person or an Affiliate or Associate of any such Person). Upon the delivery of a certificate from an appropriate officer of the Company which states that the proposed supplement or amendment is in compliance with the terms of this Section 27, and such supplement or amendment does not change or increase the Rights Agent's 40

41 duties, liabilities or obligations, the Rights Agent shall execute such supplement or amendment. Notwithstanding anything contained in this Agreement to the contrary, no supplement or amendment shall be made which changes the Redemption Price or the Final Expiration Date. Prior to the Distribution Date, the interests of the holders of Rights shall be deemed coincident with the interests of the holders of Common Stock. Section 28. Successors. All the covenants and provisions of this Agreement by or for the benefit of the Company or the Rights Agent shall bind and inure to the benefit of their respective successors and assigns hereunder. Section 29. Determination and Actions by the Board of Directors. Etc. For all purposes of this Agreement, any calculation of the number of shares of Common Stock outstanding at any particular time, including for purposes of determining the particular percentage of such outstanding shares of Common Stock of which any Person is the Beneficial Owner, shall be made in accordance with the last sentence of Rule 13d-3(d)(1)(i) of the General Rules and Regulations under the Exchange Act. The Board of Directors of the Company (or, as set forth herein, certain specified members thereof) shall have the exclusive power and authority to administer this Agreement and to exercise all rights and powers specifically granted to the Board of Directors of the Company or to the Company, or as may be necessary or advisable in the administration of this Agreement, including, without limitation, the right and power to (i) interpret the provisions of this Agreement, and (ii) make all determinations deemed necessary or advisable for the administration of this Agreement (including, but not limited to, a determination to redeem or not redeem the Rights, or to amend this Agreement). All such actions, calculations, interpretations and determinations (including, for purposes of clause (y) below, all omissions with respect to the foregoing) which are done or made by the Board of Directors of the Company, shall (x) be final, conclusive and binding on the Company, the Rights Agent, the holders of the Rights and all other parties, and (y) not subject any member of the Board of Directors to any liability to the holders of the Rights or to any other Person.

Nothing in this Agreement shall be construed to give to any Person other than the Company, the Rights Agent and the registered holders of the Rights Certificates (and, prior to the Distribution Date, registered holders of the Common Stock) any legal or equitable right, remedy or claim under this Agreement; but this Agreement shall be for the sole and exclusive benefit of the Company, the Rights Agent and the registered holders of the Rights Certificates (and, prior to the Distribution Date, registered holders of the Common Stock). Section 31. Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way 41

42 be affected, impaired or invalidated; provided, however, that notwithstanding anything in this Agreement to the contrary, if any such term, provision, covenant or restriction is held by such court or authority to be invalid, void or unenforceable and the Board of Directors of the Company determines in its good faith judgment that severing the invalid language from this Agreement would adversely affect the purpose or effect of this Agreement, the right of redemption set forth in Section 23 hereof shall be reinstated and shall not expire until the close of business on the tenth day following the date of such determination by the Board of Directors of the Company. Section 32. Governing Law. This Agreement, each Right and each Rights Certificate issued hereunder shall be deemed to be a contract made under the laws of the State of Delaware and for all purposes shall be governed by and construed in accordance with the laws of such State applicable to contracts made and to be performed entirely within such State; provided, however, all provisions regarding the rights, duties and obligations of the Rights Agent shall be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed entirely with such state.

Hoffman, President and Chief Executive Officer, and Kenneth A. Olson, Secretary, of Berry Petroleum Company, a corporation organized and existing under the General Corporation Law of the State of Delaware, in accordance with provisions of Section 103 thereof, DO HEREBY CERTIFY: That pursuant to the authority conferred upon the Board of Directors by the Restated Certificate of Incorporation of said Corporation, said Board of Directors on November 18, 1999, adopted the following resolution creating a series of 250,000 shares of Preferred Stock designated as "Series B Junior Participating Preferred Stock:" RESOLVED, that pursuant to the authority vested in the Board of Directors of the Corporation by the Restated Certificate of Incorporation, the Board of Directors does hereby provide for the issue of a series of Junior Preferred Stock, $0.01 par value, of the Corporation, to be designated "Series B Junior Participating Preferred Stock" (hereinafter referred to as the "Series B Preferred Stock"), initially consisting of 250,000 shares, and to the extent that the designations, powers, preferences and relative and other special rights and the qualifications, limitations and restrictions of the Series B Preferred Stock are not stated and expressed in the Restated Certificate of Incorporation, does hereby fix and herein state and express such designations, powers, preferences and relative and other special rights and the qualifications, limitations and restrictions thereof as follows (all terms used herein which are defined in the Restated Certificate of Incorporation shall be deemed to have the meanings provided therein): A. Designation and Amount. The shares of such series shall be designated as "Series B Junior Participating Preferred Stock" and the number of shares constituting such series shall be 250,000. Such number of shares may be increased or decreased by resolution of the Board of Directors; provided, however, that no decrease EX A-1

A-2 shall reduce the number of shares of Series B Junior Participating Preferred Stock to a number less than the number of shares then outstanding plus the number of shares reserved for issuance upon the exercise of outstanding options, rights or warrants or upon the conversion of any outstanding securities issued by the Corporation convertible into Series B Junior Participating Preferred Stock. B. Dividends and Distributions. (1) Subject to the prior and superior rights of the holders of any shares of any series of Preferred Stock ranking prior and superior to the shares of Series B Junior Participating Preferred Stock with respect to dividends, the holders of shares of Series B Junior Participating Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for the purpose, quarterly dividends payable in cash on the 15th day of January, April, July and October in each year (each such date being referred to herein as a "Quarterly Dividend Payment Date"), commencing on the first Quarterly Dividend Payment Date after the first issuance of a share or fraction of a share of Series B Junior Participating Preferred Stock, in an amount per share (rounded to the nearest cent) equal to the greater of (a) $0.25 or (b) subject to the provision for adjustment hereinafter set forth, 100 times the aggregate per share amount of all cash dividends, and 100 times the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions other than a dividend payable in shares of Common Stock or a subdivision of the outstanding shares of Common Stock (by reclassification or otherwise), declared on the Common Stock, par value $0.01 per share, of the Corporation (the "Common Stock") since the immediately preceding Quarterly Dividend Payment Date, or, with respect to the first Quarterly Dividend Payment Date, since the first issuance of any share or fraction of a share of Series B Junior Participating Preferred Stock. In the event the Corporation shall at any time after December 8, 1999 (the "Rights Declaration Date") (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the amount to which holders of shares of Series B Junior Participating Preferred Stock were entitled immediately prior to such event under Clause (b) of the preceding sentence shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. (2) The Corporation shall declare a dividend or distribution on the Series B Junior Participating Preferred Stock as provided in Paragraph B(1) above immediately after it declares a dividend or distribution on the Common Stock (other than a dividend payable in shares of Common Stock); provided, however, that, in the event no dividend or distribution shall have been declared on the Common Stock A-2

A-3 during the period between any Quarterly Dividend Payment Date, a dividend of $0.25 per share on the Series B Junior Participating Preferred Stock shall nevertheless be payable on such subsequent Quarterly Dividend Payment Date. (3) Dividends shall begin to accrue and be cumulative on outstanding shares of Series B Junior Participating Preferred Stock from the Quarterly Dividend Payment Date next preceding the date of issue of such shares of Series B Junior Participating Preferred Stock, unless the date of issue of such shares is prior to the record date for the first Quarterly Dividend Payment Date, in which case dividends on such shares shall begin to accrue from the date of issue of such shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a date after the record date for the determination of holders of shares of Series B Junior Participating Preferred Stock entitled to receive a quarterly dividend and before such Quarterly Dividend Payment Date, in either of which events such dividends shall begin to accrue and be cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on the shares of Series B Junior Participating Preferred Stock in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be allocated pro rata on a share-by-share basis among all such shares at the time outstanding. The Board of Directors may fix a record date for the determination of holders of shares of Series B Junior Participating Preferred Stock entitled to receive payment of a dividend or distribution declared thereon, which record date shall be no more than 30 days prior to the date fixed for the payment thereof. C. Voting Rights. The holders of shares of Series B Junior Participating Preferred Stock shall have the following voting rights: (1) Subject to the provision for adjustment hereinafter set forth, each share of Series B Junior Participating Preferred Stock shall entitle the holders thereof to 100 votes on all matters submitted to a vote of the stockholders of the Corporation. In the event the Corporation shall at any time after the Rights Declaration Date (a) declare any dividend on Common Stock payable in shares of Common Stock, (b) subdivide the outstanding Common Stock, or (c) combine the outstanding Common Stock into a smaller number of shares, then in each case the number of votes per share to which holders of shares of Series B Junior Participating Preferred Stock were entitled immediately prior to such event shall be adjusted by multiplying such number by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. (2) Except as otherwise provided herein or by law, the holders of shares of Series B Junior Participating Preferred Stock and the holders of shares of Common A-3

A-4 Stock shall vote together as one class on all matters submitted to a vote of stockholders of the Corporation. (3) (a) If at any time dividends on any Series B Junior Participating Preferred Stock shall be in arrears in an amount equal to six quarterly dividends thereon, the occurrence of such contingency shall mark the beginning of a period (herein called a "Default Period") that shall extend until such time when all accrued and unpaid dividends for all previous quarterly dividend periods and for the current quarterly dividend period on all shares of Series B Junior Participating Preferred Stock then outstanding shall have been declared and paid or set apart for payment. During each Default Period, all holders of Preferred Stock (including holders of the Series B Junior Participating Preferred Stock) upon which these or like voting rights have been conferred and are exercisable (the "Voting Preferred Stock") with dividends in arrears in an amount equal to six quarterly dividends thereon, voting as a class, irrespective of series, shall have the right to elect two Directors. (b) During any Default Period, such voting right of the holders of Series B Junior Participating Preferred Stock may be exercised initially at a special meeting called pursuant to Paragraph C(3)(c) or at any annual meeting of stockholders, and thereafter at annual meetings of stockholders, provided that neither such voting right nor the right of the holders of any other series of Voting Preferred Stock, if any, to increase, in certain cases, the authorized number of Directors shall be exercised unless the holders of ten percent in number of shares of Voting Preferred Stock outstanding shall be present in person or by proxy. The absence of a quorum of the holders of Common Stock shall not affect the exercise by the holders of Voting Preferred Stock of such voting right. At any meeting at which the holders of Voting Preferred Stock shall exercise such voting right initially during an existing Default Period, they shall have the right, voting as a class, to elect Directors to fill such vacancies, if any, in the Board of Directors as may then exist up to two Directors or, if such right is exercised at an annual meeting, to elect two Directors. If the number that may be so elected at any special meeting does not amount to the required number, the holders of the Voting Preferred Stock shall have the right to make such increase in the number of Directors as shall be necessary to permit the election by them of the required number. After the holders of the Voting Preferred Stock shall have exercised their right to elect Directors in any Default Period and during the continuance of such period, the number of Directors shall not be increased or decreased except by vote of the holders of Voting Preferred Stock as herein provided or pursuant to the rights of any equity securities ranking senior to or pari passu with the Series B Junior Participating Preferred Stock. (c) Unless the holders of Voting Preferred Stock shall, during an existing Default Period, have previously exercised their right to elect Directors, the Board of Directors may order, or any stockholder or stockholders owning in the A-4

A-5 aggregate not less than ten percent of the total number of shares of Voting Preferred Stock outstanding, irrespective of series, may request, the calling of a special meeting of the holders of Voting Preferred Stock, which meeting shall thereupon be called by the Chairman of the Board, the President, a Vice President or the Secretary of the Corporation. Notice of such special meeting and of any annual meeting at which holders of Voting Preferred Stock are entitled to vote pursuant to this Paragraph shall be given to each holder of record of Voting Preferred Stock by mailing a copy of such notice to each holder at their last address as the same appears on the books of the Corporation. Such special meeting shall be called for a time not earlier than 10 days and not later than 60 days after such order or request or, in default of the calling of such special meeting within 60 days after such order or request, such special meeting may be called on similar notice by any stockholder or stockholders owning in the aggregate not less than ten percent of the total number of shares of Voting Preferred Stock outstanding. Notwithstanding the provisions of this Paragraph, no such special meeting shall be called during the period within 60 days immediately preceding the date fixed for the next annual meeting of the stockholders. (d) In any Default Period, the holders of Common Stock, and other classes of stock of the Corporation, if applicable, shall continue to be entitled to elect the whole number of Directors until the holders of Voting Preferred Stock shall have exercised their right to elect two Directors voting as a class, after the exercise of which right (x) the Directors so elected by the holders of Voting Preferred Stock shall continue in office until their successors shall have been elected by such holders or until the expiration of the Default Period, and (y) any vacancy in the Board of Directors may (except as provided in Paragraph C(3)(b)) be filled by vote of a majority of the remaining Directors theretofore elected by the holders of the class of stock which elected the Director whose office shall have become vacant. References in this Paragraph to Directors elected by the holders of a particular class of stock shall include Directors elected by such Directors to fill vacancies as provided in Clause (y) of the foregoing sentence. (e) Immediately upon the expiration of a Default Period, (x) the right of the holders of Voting Preferred Stock as a class to elect Directors shall cease, (y) the term of any Directors elected by the holders of Voting Preferred Stock as a class shall terminate, and (z) the number of Directors shall be such number as may be provided for in the Restated Certificate of Incorporation or By-Laws irrespective of any increase made pursuant to the provisions of Paragraph C(3)(b) (such number being subject, however, to change thereafter in any manner provided by law or in the Restated Certificate of Incorporation or By-Laws). Any vacancies in the Board of Directors effected by the provisions of Clauses (y) and (z) in the preceding sentence may be filled by a majority of the remaining Directors. A-5

A-6 (4) Except as set forth herein, holders of Series B Junior Participating Preferred Stock shall have no special voting rights and their consent shall not be required (except to the extent they are entitled to vote with holders of Common Stock as set forth herein) for taking any corporate action. D. Certain Restrictions. (1) Whenever quarterly dividends or other dividends or distributions payable on the Series B Junior Participating Preferred Stock as provided in Paragraph B are in arrears, thereafter and until all accrued and unpaid dividends and distributions, whether or not declared, on shares of Series B Junior Participating Preferred Stock outstanding shall have been paid in full, the Corporation shall not: (a) Declare or pay dividends on, make any other distribution on, or redeem or purchase or otherwise acquire for consideration any shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series B Junior Participating Preferred Stock; (b) Declare or pay dividends on or make any other distributions on any shares of stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series B Junior Participating Preferred Stock, except dividends paid ratably on the Series B Junior Participating Preferred Stock and all such parity stock on which dividends are payable or in arrears in proportion to the total amounts to which the holders of all such shares are then entitled; (c) Redeem or purchase or otherwise acquire for consideration shares of any stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series B Junior Participating Preferred Stock, provided that the Corporation may at any time redeem, purchase or otherwise acquire shares of any such parity stock in exchange for shares of any stock of the Corporation ranking junior (either as to dividends or upon dissolution, liquidation for winding up) to the Series B Junior Participating Preferred Stock; or (d) Purchase or otherwise acquire for consideration any shares of Series B Junior Participating Preferred Stock, or any shares of stock ranking on a parity with the Series B Junior Participating Preferred Stock, except in accordance with a purchase offer made in writing or by publication (as determined by the Board of Directors) to all holders of such shares upon such terms as the Board of Directors, after consideration of the respective annual dividend rates and other relative rights and preferences of the respective series and classes, shall determine in good faith will result in fair and equitable treatment among the respective series or classes. A-6

A-7 (2) The Corporation shall not permit any subsidiary of the Corporation to purchase or otherwise acquire for consideration any shares of stock of the Corporation unless the Corporation could, under Paragraph D(1), purchase or otherwise acquire such shares at such time and in such manner. E. Reacquired Shares. Any shares of Series B Junior Participating Preferred Stock purchased or otherwise acquired by the Corporation in any manner whatsoever shall be retired and canceled promptly after the acquisition thereof. All such shares shall upon their cancellation become authorized but unissued shares of Preferred Stock and may be reissued as part of a new series of Preferred Stock to be created by resolution or resolutions of the Board of Directors, subject to the conditions and restrictions on issuance set forth herein. F. Liquidation, Dissolution or Winding Up. (1) Upon any liquidation (voluntary or otherwise), dissolution or winding up of the Corporation, no distribution shall be made to the holders of shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series B Junior Participating Preferred Stock unless, prior thereto, the holders of shares of Series B Junior Participating Preferred Stock shall have received $100 per share, plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment (the "Series B Liquidation Preference"). Following the payment of the full amount of the Series B Liquidation Preference, no additional distributions shall be made to the holders of shares of Series B Junior Participating Preferred Stock unless, prior thereto, the holders of shares of Common Stock shall have received an amount per share (the "Common Adjustment") equal to the quotient obtained by dividing (a) the Series B Liquidation Preference by (b) 100 (as appropriately adjusted as set forth in Paragraph F(3) below to reflect such events as stock splits, stock dividends and recapitalizations with respect to the Common Stock) (such number in Clause (b), the "Adjustment Number"). Following the payment of the full amount of the Series B Liquidation Preference and the Common Adjustment in respect of all outstanding shares of Series B Junior Participating Preferred Stock and Common Stock, respectively, holders of Series B Preferred Stock and holders of shares of Common Stock shall receive their ratable and proportionate share of remaining assets to be distributed in the ratio of the Adjustment Number to 1 with respect to such Preferred Stock and Common Stock, on a per share basis, respectively. (2) In the event, however, that there are not sufficient assets available to permit payment in full of the Series B Liquidation Preference and the liquidation preferences of all other series of Preferred Stock, if any, which rank on a parity with the Series B Junior Participating Preferred Stock, then such remaining assets shall be distributed ratably to the holders of such parity shares in proportion to their respective A-7

A-8 liquidation preferences. In the event, however, that there are not sufficient assets available to permit payment in full of the Common Adjustment, then such remaining assets shall be distributed ratably to the holders of Common Stock. (3) In the event the Corporation shall at any time after the Rights Declaration Date (a) declare any dividend on Common Stock payable in shares of Common Stock, (b) subdivide the outstanding Common Stock, or (c) combine the outstanding Common Stock into a smaller number of shares, then in each such case the Adjustment Number in effect immediately prior to such event shall be adjusted by multiplying such Adjustment Number by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. G. Consolidation, Merger, Etc. In the event the Corporation shall enter into any consolidation, merger, combination or other transaction in which the shares of Common Stock are exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case the shares of Series B Junior Participating Preferred Stock shall at the same time be similarly exchanged or changed in an amount per share (subject to the provision for adjustment hereinafter set forth) equal to 100 times the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the case may be, into which or for which each share of Common Stock is changed or exchanged. In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the amount set forth in the preceding sentence with respect to the exchange or change of shares of Series B Junior Participating Preferred Stock shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. H. No Redemption. The shares of Series B Junior Participating Preferred Stock shall not be redeemable. I. Ranking. The Series B Junior Participating Preferred Stock shall rank junior to all other series of the Corporation's preferred stock, if any, as to the payment of dividends and the distribution of assets, unless the terms of any such series shall provide otherwise. J. Amendment. The Restated Certificate of Incorporation of the Corporation shall not be further amended in any manner which would materially alter or change A-8

A-9 the powers, preferences or special rights of the Series B Junior Participating Preferred Stock so as to affect them adversely without the affirmative vote of the holders of a majority or more of the outstanding shares of Series B Junior Participating Preferred Stock, voting separately as a class. K. Fractional Shares. Series B Junior Participating Preferred Stock may be issued in fractions of a share, which shall entitle the holder, in proportion to such holder's fractional shares, to exercise voting rights, receive dividends, participate in distributions and to have the benefit of all other rights of holders of Series B Junior Participating Preferred Stock. RESOLVED FURTHER, that the proper officers of the Corporation be, and each of them hereby is, authorized to execute a Certificate of Designation with respect to the Series B Junior Participating Preferred Stock pursuant to Section 151 of the General Corporation Law of the State of Delaware and to take all appropriate action to cause such Certificate of Designation to become effective, including, but not limited to, the filing and recording of such Certificate with and/or by the Secretary of State of the State of Delaware. IN WITNESS WHEREOF, we have executed and subscribed this Certificate of Designation and do affirm the foregoing as true under the penalties of perjury this 18 day of November, 1999 /s/ Jerry V.

C-1 Exhibit C BERRY PETROLEUM COMPANY SUMMARY OF RIGHTS TO PURCHASE PREFERRED STOCK On November 18, 1999 (the "Rights Dividend Declaration Date"), the Board of Directors of Berry Petroleum Company (the "Company") declared a dividend of one Right (a "Right") for each outstanding share of capital stock (Class A Common Stock "Common Stock" and Class B Stock) to be distributed to stockholders of record at the close of business on December 8, 1999. Each Right entitles the registered holder to purchase from the Company one one-hundredth of a share (a "Unit") of Series B Junior Participating Preferred Stock, par value $0.01 per share (the "Preferred Stock"), at a Purchase Price of $38.00, subject to adjustment. The description and terms of the Rights are set forth in a Rights Agreement (the "Rights Agreement") between the Company and ChaseMellon Shareholder Services, L.L.C., as Rights Agent. Initially, the Rights will be attached to all capital stock certificates representing shares then outstanding, and no separate Rights Certificates will be distributed. The Rights will separate from such stock and a Distribution Date will occur (the "Distribution Date") upon the earlier of (i) 10 days following a public announcement that a person or group of affiliated or associated persons other than the Company, any subsidiary of the Company, any employee benefit plan or employee stock plan of the Company or any subsidiary of the Company, any person or entity organized, appointed or established by the Company for or pursuant to the terms of any such plan, or any person who or which, together with its Affiliates and Associates, shall become the Beneficial Owner of 20% or more of the shares of Common Stock then outstanding solely as a result of a reduction in the number of shares of Common Stock outstanding due to a repurchase of Common Stock by the Company, unless such person shall thereafter purchase or otherwise become the Beneficial Owner of additional shares of Common Stock representing 1% of the shares of Common Stock then outstanding (an "Exempt Person") who or which, without the consent of the Company, has acquired, or obtained the right to acquire, beneficial ownership of 20% or more of the outstanding shares of Common Stock (such person or group being referred to as an "Acquiring Person" and such date being referred to as the "Stock Acquisition Date"), or (ii) 10 business days following the commencement of a tender offer or exchange offer that would result in a person or group (other than an Exempt Person or a person approved by the Company) beneficially owning 20% or more of such outstanding shares of Common Stock. Until the Distribution Date (or earlier redemption, exchange or expiration of the Rights), (i) the Rights will be evidenced by the capital stock certificates and this C-1

C-2 Summary of Rights and will be transferred with and only with such certificates, (ii) new capital stock certificates issued after December 8, 1999 will contain a notation incorporating the Rights Agreement by reference, and (iii) the surrender for transfer of any certificates for capital stock outstanding will also constitute the transfer of the Rights associated with the stock represented by such certificates. The Rights are not exercisable until the Distribution Date and will expire at the close of business on December 8, 2009, unless earlier redeemed or exchanged by the Company or terminated, as described in the Rights Agreement. As soon as practicable after the Distribution Date, Rights Certificates will be mailed to holders of record of the Common Stock (and Class B Stock, if applicable) as of the close of business on the Distribution Date and, thereafter, the separate Rights Certificates alone will represent the Rights. In the event that at any time following the Rights Dividend Declaration Date, a person becomes an Acquiring Person, (except pursuant to an offer for all outstanding shares of Common Stock which a majority of the independent directors determine to be fair to and otherwise in the best interests of the Company and its stockholders), then each holder of a Right will thereafter have the right to receive, upon exercise, Common Stock (or, in certain circumstances, cash, property or other securities of the Company) having a value equal to two times the exercise price of the Right. Rights are exercisable following the occurrence of the foregoing only at such time as the Rights are not redeemable by the Company. Notwithstanding any of the foregoing, following the occurrence of the event set forth in this paragraph, all Rights that are, or (under certain circumstances specified in the Rights Agreement) were, beneficially owned by any Acquiring Person will be null and void. An example of the effect of the preceding paragraph is as follows. At an exercise price of $30.00 per Right, each Right not owned by an Acquiring Person (or by certain related parties) following the event set forth in the preceding paragraph would entitle its holder to purchase $60.00 worth of Common Stock (or other consideration, as noted above) for $30.00. Assuming that the Common Stock had a per share value of $10.00 at such time, the holder of each valid Right would be entitled to purchase six shares of Common Stock for $30.00. In the event that, at any time following the Stock Acquisition Date, (i) the Company is acquired in a merger or other business combination transaction in which the Company is not the surviving corporation or in which the Company's outstanding Common Stock is exchanged for cash, stock or other property (other than a merger which follows an offer described in the second preceding paragraph), or (ii) 50% or more of the Company's assets or earning power is sold or transferred, each holder of a Right (except Rights which previously have been voided as set forth above) shall thereafter C-2

C-3 have the right to receive, upon exercise, common stock of the Principal Party in such transaction, having a value equal to two times the exercise price of the Right. The Purchase Price payable, and the number of Units of Preferred Stock or other securities or property issuable, upon exercise of the Rights are subject to adjustment from time to time to prevent dilution, as set forth in the Rights Agreement. With certain exceptions, no adjustment in the Purchase Price will be required until cumulative adjustments amount to at least 1% of the Purchase Price. No fractional Rights, fractions of shares of Preferred Stock (other than fractions which are integral multiples of one one-hundredth of a share), or fractional shares of Common Stock will be issued and, in lieu thereof, an adjustment in cash will be made based on the market price of the Rights, Preferred Stock, or Common Stock, respectively, on the last trading date prior to the date of exercise. In general, the Company may redeem the Rights in whole, but not in part, at a price of $0.01 per Right, at any time until the Distribution Date. Immediately upon the action of the Board of Directors ordering redemption of the Rights, the Rights will terminate and the only right of the holders of Rights will be to receive the $0.01 per right redemption price. After the Distribution Date, the Company's ability to redeem the rights could be reinstated in certain circumstances, subject to certain conditions, in connection with a permitted transaction not involving an Acquiring Person or where an Acquiring Person has decreased its beneficial ownership in the Company to less than 10% of the then outstanding shares of Common Stock and there is no other Acquiring Person. Until a Right is exercised, the holder thereof, as such, will have no rights as a stockholder of the Company, including, without limitation, the right to vote or to receive dividends. The Board has the option, under certain circumstances, to exchange the rights for stock instead of requiring holders to exercise their rights, whereupon the holders' rights to exercise their rights would terminate. Other than those provisions relating to the redemption price or the final expiration date of the Rights, any of the provisions of the Rights Agreement may be supplemented or amended by the Company prior to the Distribution Date, without approval of the Rights holders, whether or not a supplement or amendment is adverse to the Rights holders. After the Distribution Date, the provisions of the Rights Agreement (other than the provisions relating to the redemption price or the final expiration date of the Rights) may be amended by the Company in order to make changes which do not materially and adversely affect the interests of holders of Rights (excluding the interests of any Acquiring Person).

A copy of the Rights Agreement is available free of charge from the Company.
