ARTICLE II

EXCHANGE

Section 2.1    Redemption and Purchase Rights.

(a)    Subject to Section 4.4(b) of the OpCo Limited Liability Company Agreement, Energen shall have the right, at any time and from time to time (subject to the terms and conditions set forth herein), to require the Partnership to redeem (each, a “Redemption”) all or a portion of the Class B Units held by Energen, which must be accompanied by an equal number of OpCo Units held by Energen (one OpCo Unit and one Class B Unit are referred to herein as one “Unit”, and Units that have in fact been tendered for redemption being hereafter referred to as “Tendered Units”), in exchange for the Common Unit Amount and the Redemption Amount. The Partnership shall deliver to Energen the Redemption Amount on the same date that it delivers the Common Unit Amount.

4

(i)    If Energen desires to exercise its right to require a Redemption, it shall deliver a written notice to the Partnership and the Operating Company specifying the number of Units Energen desires to tender for redemption (the “Notice of Redemption”). The Partnership shall not be obligated to effect a Redemption until the Specified Redemption Date (it being understood that the Partnership will not be required to consummate such Redemption with respect to any Tendered Units that are purchased by the Partnership pursuant to Section 2.1(b)).

(ii)    The Common Unit Amount shall be delivered by the Partnership on or before the Specified Redemption Date as duly authorized, validly issued, fully paid and non-assessable Common Units (except as such nonassessability may be affected by Sections 17-303, 17-607 or 18-704 of the Delaware LP Act), free of any pledge, lien, encumbrance or restriction, other than the restrictions provided in the Partnership Agreement, the Securities Act and relevant state securities or “blue sky” laws. Notwithstanding any delay in such delivery, Energen shall be deemed the owner of such Common Units for all purposes, including, without limitation, rights to vote and consent, receive distributions, and exercise rights, as of the Specified Redemption Date. Common Units issued upon a Redemption pursuant to this Section 2.1(a) may contain such legends regarding restrictions under the Securities Act and applicable state securities laws as the Partnership in good faith determines to be necessary or advisable in order to ensure compliance with such laws.

(b)    In lieu of any Redemption described in Section 2.1(a), the Partnership may, in its sole and absolute discretion (but subject to the approval of the Conflicts Committee), offer to purchase some or all of the Tendered Units (such amount, expressed as a percentage of the total number of Tendered Units rounded up to the nearest Unit, being referred to as the “Applicable Percentage”) from Energen by delivering a written notice of such election on or before the close of business on the Cut-Off Date. If Energen accepts such offer in writing, on the Specified Redemption Date Energen shall sell such number of the Tendered Units to the Partnership in exchange for a cash sum (the “Cash Purchase Price”) equal to (x) the Redemption Amount plus (y) the product of the Cash Amount and the Applicable Percentage. If the Partnership offers, subject to the approval of the Conflicts Committee, to purchase some or all of the Tendered Units and Energen accepts such offer:

(i)    the Cash Purchase Price shall be delivered, in Energen’s sole and absolute discretion, by wire transfer or as a certified or bank check payable to Energen, in each case in immediately available funds and on or before the Specified Redemption Date; and

(ii)    the remaining Tendered Units shall be subject to Redemption pursuant to Section 2.1(a).

(c)    In the event the Partnership elects to exercise its offer rights pursuant to Section 2.1(b), the Partnership shall provide a written notice to that effect (an “Exercise Notice”) to the Operating Company and Energen on or before the close of business on the Cut-Off Date. The failure of the Partnership to provide an Exercise Notice by the close of business on the Cut-Off Date shall be deemed to be an election by the Partnership not to make an offer to purchase any of the Tendered Units. Energen shall have five (5) Business Days after receipt of the Exercise Notice to give written notice of acceptance.

5

(d)    Without limiting the remedies of Energen, if the Partnership offers to purchase some or all of the Tendered Units under Section 2.1(b) for the Cash Purchase Price and Energen accepts, and the Cash Purchase Price is not paid on or before the Specified Redemption Date, interest shall accrue with respect to the Cash Purchase Price from the day after the Specified Redemption Date to and including the date on which the Cash Purchase Price is paid at a rate equal to the Applicable Federal Short-Term Rate as published monthly by the United States Internal Revenue Service.

(e)    Notwithstanding anything herein to the contrary, with respect to any Redemption pursuant to Section 2.1(a), or any purchase of Units by the Partnership pursuant to Section 2.1(b) hereof:

(i)    Without the consent of the Partnership, Energen may not effect a Redemption for (A) less than one thousand (1,000) Units or (B) if Energen holds less than one thousand (1,000) Units, all of the Units held by Energen.

(ii)    If (A) Energen surrenders Tendered Units during the period after the Record Date with respect to a distribution payable to Holders of OpCo Units, and before the record date established by the Partnership for a distribution to its unitholders of some or all of its portion of such Operating Company distribution, and (B) the Partnership elects to purchase any of such Tendered Units pursuant to Section 2.1(b), then Energen shall pay to the Partnership on the Specified Redemption Date an amount in cash equal to the Operating Company distribution paid or payable in respect of such Tendered Units.

(iii)    Notwithstanding anything to the contrary herein, the consummation of a Redemption pursuant to Section 2.1(a) hereof or a purchase of Tendered Units by the Partnership pursuant to Section 2.1(b) hereof, as the case may be, shall not be permitted to the extent the Partnership determines that such Redemption or purchase (A) would be prohibited by applicable law or regulation (including, without limitation, the Securities Act, the Delaware LLC Act or the Delaware LP Act) or (B) would not be permitted under the Partnership Agreement, the OpCo Limited Liability Company Agreement or any other agreements to which the Partnership or the Operating Company may be party or any written policies of the Partnership related to unlawful or improper trading (including, without limitation, the policies of the Partnership relating to insider trading).

(f)    The Partnership, the Operating Company and Energen shall bear their own expenses in connection with the consummation of any Exchange, whether or not any such Exchange is ultimately consummated, except that the Operating Company shall bear any transfer taxes, stamp taxes or duties, or other similar taxes in connection with, or arising by reason of, any Exchange; provided, however, that if any Common Units are to be delivered in a name other than that of Energen, then Energen and/or the person in whose name such shares are to be delivered shall pay to the Operating Company the amount of any transfer taxes, stamp taxes or duties, or other similar taxes in connection with, or arising by reason of, such Exchange or shall establish to the reasonable satisfaction of the Partnership that such tax has been paid or is not payable.

6

Section 2.2    Expiration. In the event that the Operating Company is dissolved pursuant to the OpCo Limited Liability Company Agreement, any Exchange Right pursuant to Section 2.1 of this Agreement shall terminate upon final distribution of the assets of the Operating Company pursuant to the terms and conditions of the OpCo Limited Liability Company Agreement.

Section 2.3    Adjustment. If there is any reclassification, reorganization, recapitalization or other similar transaction in which the OpCo Units, Common Units or Class B Units, as applicable, are converted or changed into another security, securities or other property, then upon any subsequent Exchange, Energen shall be entitled to receive the amount of such security, securities or other property that Energen would have received if such Exchange had occurred immediately prior to the effective date of such reclassification, reorganization, recapitalization or other similar transaction, taking into account any adjustment as a result of any subdivision (by any split, distribution or dividend, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse split, reclassification, recapitalization or otherwise) of such security, securities or other property that occurs after the effective time of such reclassification, reorganization, recapitalization or other similar transaction. For the avoidance of doubt, if there is any reclassification, reorganization, recapitalization or other similar transaction in which the OpCo Units, Common Units or Class B Units, as applicable, are converted or changed into another security, securities or other property, this Section 2.3 shall continue to be applicable, mutatis mutandis, with respect to such security or other property. This Agreement shall apply to, mutatis mutandis, and all references to “OpCo Units,” “Common Units” or “Class B Units” shall be deemed to include, any security, securities or other property of the Operating Company or the Partnership, as applicable, which may be issued in respect of, in exchange for or in substitution of the OpCo Units, Common Units or Class B Units, as applicable, by reason of any distribution or dividend, split, reverse split, combination, reclassification, reorganization, recapitalization, merger, exchange (other than an Exchange) or other transaction.
