The Shares granted hereunder are subject to the Plan. The terms and provisions of the Plan, as it may be amended from time to time, are hereby incorporated herein by reference. In the event of a conflict between any term or provision contained herein and a term or provision of the Plan, the applicable terms and provisions of the Plan will govern and prevail.

Subject to the provisions of Section 13:

The total number of Shares which may be issued under the Plan is 200,000,000, of which no more than 20% may be issued in the form of Restricted Stock or Other Stock-Based Awards payable in Shares. The maximum aggregate number of Shares with respect to which Awards may be granted during a calendar year, net of any Shares which are subject to Awards (or portions thereof) which, during such year, terminate or lapse without payment of consideration, shall be equal to 2% of the number of Shares outstanding on December 31 of the preceding calendar year. The maximum number of Shares with respect to which Awards may be granted during a calendar year to any Participant shall be 2,000,000; provided that the maximum number of Shares that may be awarded in the form of Restricted Stock or Other Stock-Based Awards payable in Shares during any calendar year to any Participant shall be 600,000. The Shares may consist, in whole or in part, of unissued Shares or treasury Shares. The number of Shares available for issuance under the Plan shall be reduced by the full number of Shares covered by Awards granted under the Plan (including, without limitation, the full number of Shares covered by any Stock Appreciation Right, regardless of whether any such Stock Appreciation Right or other Award covering Shares under the Plan is ultimately settled in cash or by delivery of Shares); provided, however, that the number of Shares covered by Awards (or portions thereof) that are forfeited or that otherwise terminate or lapse without the payment of consideration in respect thereof shall again become available for issuance under the Plan; and provided further that any Shares that are forfeited after the actual issuance of such Shares to a Participant under the Plan shall not become available for re-issuance under the Plan.

Shares Subject to the Plan. Subject to [Section 16] of the Plan, the maximum aggregate number of Shares that may be subject to Awards under the Plan shall be 3,952,095, which amount (the “Gross Share Reserve”) consists of the sum of # the Shares Convertible from Plan Notes and # 3,315,218 additional Shares (the “Net Share Reserve”). The Gross Share Reserve, which is an amount equal to eight and three tenths percent (8.3%) of the Shares outstanding as of the Effective Date on a fully diluted basis, shall be divided into three grant pools:

Subject to adjustment in accordance with Section 3, as of March 3, 2016, 1,882,581 shares of Stock were reserved and available for issuance under the Plan for future Awards (reflecting the original 650,000-share authorization, the 1998 stock split adjustment, an additional 1,500,000 shares authorized at the January 2002 shareholder meeting, the 2005 stock split adjustment and 3,000,000 shares authorized at the April 2011 shareholder meeting, reduced by prior Awards). Shares of Stock allocable to an Award or portion of an Award that is canceled by forfeiture, expiration or for any other reason (excepting pursuant to a stock appreciation right election under Section 6.2(i)) shall again be available for additional Awards. If any option granted under the Plan shall be canceled as to any shares of Stock pursuant to Section 6.2(i) (stock appreciation rights), then such shares of Stock shall not be available for the grant of another Award. Shares of Stock not issued as the result of the net exercise of a stock appreciation right, shares tendered by the Participant or retained by Energen as full or partial payment to Energen for the purchase of an Award or to satisfy tax withholding obligations in connection with an Award, or shares repurchased on the open market with the proceeds from the payment of an exercise price of an option shall not again be available for issuance under the Plan.

Subject to adjustment as provided in Section 13 of the Plan, a total of 250,000 shares of Company Stock may be issued pursuant to Awards under the Plan.
