Chesapeake Energy (CHK)

General

We are the largest independent producer of natural gas in the United States. We own interests in approximately 41,200 producing natural gas and oil wells that are currently producing approximately 2.3 billion cubic feet equivalent (bcfe) per day, 92% of which is natural gas. Our strategy is focused on discovering, developing and acquiring conventional and unconventional natural gas reserves onshore in the U.S., primarily in the “Big 4” natural gas shale plays: the Barnett Shale in the Fort Worth Basin of north-central Texas, the Haynesville Shale in the Ark-La-Tex area of northwestern Louisiana and East Texas, the Fayetteville Shale in the Arkoma Basin of central Arkansas and the Marcellus Shale in the northern Appalachian Basin of West Virginia, Pennsylvania and New York. We also have substantial operations in various other plays, both conventional and unconventional, in the Mid-Continent, Appalachian Basin, Permian Basin, Delaware Basin, South Texas, Texas Gulf Coast and Ark-La-Tex regions of the U.S.

We have been developing expertise in horizontal drilling technology since shortly after our inception in 1989 and have focused almost exclusively on developing natural gas properties in the U.S. since 2000. We were one of the first companies to recognize the potential of unconventional natural gas properties, especially shales, in the U.S. during the early part of this decade. During the past five years, we have grown from the eighth largest natural gas producer in the U.S. to the largest independent natural gas producer, in large part as a result of our success in finding and developing unconventional natural gas assets.

As of December 31, 2008, we had 12.051 trillion cubic feet equivalent, or tcfe, of proved reserves, of which 94% were natural gas and all of which were onshore in the U.S. During 2008, we produced an average of 2.303 bcfe per day, an 18% increase over the 1.957 bcfe per day produced in 2007. We replaced our 843 bcfe of production with an internally estimated 2.015 tcfe of new proved reserves for a reserve replacement rate of 239%. Reserve replacement through the drillbit was 2.545 tcfe, or 302% of production including 1.248 tcfe of positive performance revisions and 298 bcfe of negative revisions resulting from natural gas and oil price decreases between December 31, 2007 and December 31, 2008. Reserve replacement through the acquisition of proved reserves was 172 bcfe. During 2008, we divested 702 bcfe of estimated proved reserves. In total, our proved reserves grew by 11% during 2008, from 10.9 tcfe to 12.1 tcfe. Of our 12.1 tcfe of proved reserves, 67% were proved developed reserves.

During 2008, Chesapeake continued the industry’s most active drilling program and drilled 1,819 gross (1,491 net) operated wells and participated in another 1,857 gross (242 net) wells operated by other companies. The company’s drilling success rate was 99% for company-operated wells and 98% for non-operated wells. Also during 2008, we invested $5.043 billion in operated wells (using an average of 145 operated rigs) and $754 million in non-operated wells (using an average of 110 non-operated rigs) for total drilling, completing and equipping costs of $5.797 billion.

During the second half of 2008, we entered into joint venture arrangements that monetized a portion of our investment in three of the Big 4 Shale plays and provide drilling cost carries for our retained interest. In the Haynesville Shale, we entered into a joint venture with Plains Exploration & Production Company in July 2008 in which we sold Plains a 20% interest in our Haynesville properties and received an upfront cash payment of $1.65 billion and drilling cost carries of up to $1.65 billion. In the Fayetteville Shale, we entered into a joint venture with BP America Production Company in September 2008 in which we sold BP a 25% interest in our Fayetteville properties and received an upfront cash payment of $1.1 billion and drilling cost carries of $800 million. Most recently, we entered into a joint venture with StatoilHydro ASA in November 2008 in which we sold a 32.5% interest in our Marcellus properties and received an upfront cash payment of $1.25 billion and drilling cost carries of $2.125 billion. Collectively in these three joint ventures, we received upfront cash payments of $4.0 billion and future drilling cost carries of up to $4.6 billion for total consideration of up to $8.6 billion against a cost basis of approximately $1.2 billion in the property interests we sold. Moreover, Chesapeake retained an 80% interest in the Haynesville Shale properties, a 75% interest in the Fayetteville Shale properties and a 67.5% interest in the Marcellus Shale properties.

Section 10.2 Acceleration of Awards on Disability, Death, Retirement or Involuntary Termination. With respect to (i) a Participant who ceases to be an Eligible Person due to a Disability, (ii) the personal representative of a deceased Participant, or (iii) any other Participant who ceases to be an Eligible Person due to the Participant’s retirement or involuntary termination (as defined by the Committee), the Committee, in its sole discretion, may permit the purchase of all or any part of the shares subject to any unvested Option or waive the vesting requirements of any Award on the date the Participant ceases to be an Eligible Person due to a Disability, death, retirement or involuntary termination. With respect to Options which have already vested at such date or the vesting of which is accelerated by the Committee in accordance with the foregoing provision, the Participant or the personal representative of a deceased Participant shall have the right to exercise such vested Options within such period(s) as the Committee shall determine. The purchase of all or any part of the shares subject to any unvested Option or the waiver the vesting requirements of any Award on the date the Participant ceases to be an Eligible Person due to an involuntary termination pursuant to this Section 10.2 will be limited to 5% of the aggregate number of shares of Common Stock which are available for Awards under the Plan pursuant to Section 3.3 of the Plan.

Withholding Taxes. A Participant must pay in cash to the Company the amount of taxes required to be withheld by law upon the exercise of an Option. Required withholding taxes associated with Restricted Stock, Performance Shares, Cash or Other Stock Awards must also be paid in cash unless the Committee requires a Participant to pay the amount of taxes required by law to be withheld from such Awards by directing the Company to withhold from any Award the number of shares of Common Stock having a Fair Market Value on the date of vesting equal to the amount of required withholding taxes.

Section 10.3 Code Section 83(b) Elections.

Any Participant who makes an election pursuant to Section 83(b) will promptly provide the Committee with a copy of the election form.

Section 10.4 Code Section 162(m). It is the intent of the Company that the Plan comply in all respects with Section 162(m) of the Code and that any ambiguities or inconsistencies in construction of the Plan be interpreted to give effect to such intention.

Section 10.5 Code Section 409A. It is the intent of the Company that no Award under the Plan be subject to Section 409A of the Code. The Committee shall design and administer the Awards under the Plan so that they are not subject to Section 409A of the Code.

Section 10.6 Certain Additional Payments by the Company. The Committee may, in its sole discretion, provide in any Award Agreement for certain payments by the Company in the event that acceleration of vesting of any Award under the Plan is subject to the excise tax imposed by Section 4999 of the Code or any interest or

A-10

penalties with respect to such excise tax (such excise tax, interest and penalties, collectively, the “Excise Tax”). An Award Agreement may provide that the Participant shall be entitled to receive a payment (a “Gross-Up Payment”) in an amount such that after payment by the Participant of all taxes (including any interest or penalties imposed with respect to such taxes), including any Excise Tax imposed upon the Gross-Up Payment, the Participant retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon such acceleration of vesting of any Award.

Notwithstanding the foregoing, an Award held by a Non-Employee Director may be transferable under certain circumstances as specified by the Committee in the Award Agreement.

Section 10.8 Non-Uniform Determinations.

Section 10.9 Leaves of Absence, Suspensions. The Committee shall be entitled to make such rules, regulations and determinations as it deems appropriate under the Plan in respect of any suspension of employment or leave of absence from the Company granted to a Participant whether such suspension or leave is paid or unpaid and whether due to a Disability or otherwise. Without limiting the generality of the foregoing, the Committee shall be entitled to determine (i) whether or not any such suspension or leave of absence shall be treated as if the Participant ceased to be an employee of the Company and (ii) the impact, if any, of any such suspension or leave of absence on Awards under the Plan.

The Committee shall be entitled to make such rules, regulations and determinations as it deems appropriate under the Plan in respect of any suspension of employment or leave of absence from the Company granted to a Participant whether such suspension or leave is paid or unpaid and whether due to a Disability or otherwise. Without limiting the generality of the foregoing, the Committee shall be entitled to determine (i) whether or not any such suspension or leave of absence shall be treated as if the Participant ceased to be an employee of the Company and (ii) the impact, if any, of any such suspension or leave of absence on Awards under the Plan.
