(a) At June 30, 1997, the closing price of the Common Stock on the New York
    Stock Exchange ("NYSE") was $9.94. "In-the-money options" are stock options
    with respect to which the market value of the underlying shares of Common
    Stock exceeded the exercise price at June 30, 1997. The values shown were
    determined by subtracting the aggregate exercise price of such options from
    the aggregate market value of the underlying shares of Common Stock on June
    30, 1997.
 
(b) Represents amounts determined by subtracting the aggregate exercise price of
    such options from the aggregate market value of the underlying shares of
    Common Stock on the exercise date.
 
(c) Mr. McClendon has not sold any of such shares.
 
EMPLOYMENT AGREEMENTS
 
     The Company has employment agreements with Messrs. McClendon and Ward, each
of which provides, among other things, for an annual base salary of not less
than $300,000 commencing July 1, 1997; bonuses at the discretion of the Board of
Directors; eligibility for stock options; and benefits, including an automobile
and aircraft allowance, club membership and personal accounting support. Each
agreement has a term of three years commencing July 1, 1997, which term is
automatically extended for one additional year on each June 30 unless the
Company provides 30 days prior notice of non-extension.
 
     The employment agreements between the Company and Messrs. McClendon and
Ward permit them to participate in each well drilled by the Company on terms no
less favorable to the Company than those agreed to by unaffiliated industry
partners. Messrs. McClendon and Ward have participated in all wells drilled by
the Company since its initial public offering in February 1993 and intend to
continue participating in wells drilled by the Company under the terms of their
employment agreements. Thirty days prior to the beginning of each calendar
quarter, Messrs. McClendon and Ward and the disinterested members of the
Compensation Committee of the Board of Directors agree upon the working interest
percentage in all wells spudded during that quarter to be purchased by Messrs.
McClendon and Ward. That percentage may not be adjusted during such quarter
except with the approval of such disinterested directors. No such adjustments
have ever been requested or granted. The participation election by Messrs.
McClendon or Ward may not exceed a 2.5% working interest in a well. Messrs.
McClendon and Ward are obligated to pay within 150 days after billing all costs
and expenses associated with the working interests they acquire under this
arrangement. In addition, for each calendar year during which the employment
agreements are in effect, Messrs. McClendon and Ward each agree to hold shares
of the Company's Common Stock having an aggregate investment value equal to 500%
of his annual base salary and bonus.
 
     The Company has a similar employment agreement with Mr. Rowland. It
provides for an annual base salary of not less than $225,000 commencing July 1,
1997. The agreement has a term of three years beginning July 1, 1997, which term
is automatically extended for one additional year on each June 30 unless the
Company provides 30 days prior notice of non-extension. Mr. Rowland is permitted
to participate in wells drilled by the Company in the same manner as Messrs.
McClendon and Ward, except that Mr. Rowland's
 
                                        6
<PAGE>   8
 
working interest participation in a well may not exceed 1%. Messrs. McClendon,
Ward and Rowland may not participate in any well in which their combined working
interests cause the Company's working interest to be reduced to less than 12.5%.
Mr. Rowland agrees to hold shares of the Company's Common Stock having an
aggregate investment value equal to 100% of his annual base salary and bonus
during each calendar year for the term of the agreement.
 
     Messrs. McClendon, Ward and Rowland have agreed that they will not engage
in oil and gas operations individually except pursuant to the aforementioned
participation in Company wells and as a result of subsequent operations on
properties owned by them or their affiliates as of July 1, 1995 or acquired from
the Company with respect to Messrs. McClendon and Ward and as of March 1, 1993
with respect to Mr. Rowland.
 
     The Company also has employment agreements with Messrs. Dixon, Lester and
Hood. These agreements have a term of three years from July 1, 1997, with annual
base salaries of $175,000 for Mr. Dixon, $160,000 for Mr. Lester and $155,000
for Mr. Hood for the term of their agreements. The agreements require each of
them to acquire and continue to hold shares of the Company's Common Stock having
an annual aggregate investment value equal to 15% for Messrs. Dixon and Lester
and 10% for Mr. Hood of the annual base salary and bonus compensation paid to
them under their respective agreements.
 
     The Company may terminate any of the employment agreements with its
executive officers at any time without cause; however, upon such termination
Messrs. McClendon, Ward and Rowland are entitled to continue to receive salary
and benefits for the balance of the contract term. Messrs. Dixon, Hood and
Lester are entitled to 90 days compensation and benefits. Each of the employment
agreements for Messrs. McClendon, Ward and Rowland further states that if,
during the term of the agreement, there is a change of control and within one
year (i) the agreement expires and is not extended; (ii) the executive officer
is terminated other than for cause, death or incapacity; or (iii) the executive
resigns as a result of a reassignment of duties inconsistent with his position
or a reduction in his compensation, then the executive officer will be entitled
to a severance payment in an amount equal to 36 months of base salary
compensation. Change of control is defined in these agreements to include (x) an
event which results in a person acquiring beneficial ownership of securities
having 35% or more of the voting power of the Company's outstanding voting
securities, or (y) within two years of a tender offer or exchange offer for the
voting stock of the Company or as a result of a merger, consolidation, sale of
assets or contested election, a majority of the members of the Company's Board
of Directors is replaced by directors who were not nominated and approved by the
Board of Directors.
 
DIRECTORS' COMPENSATION
 
     During fiscal year 1997, each director who was not an officer of the
Company received $2,500 for each regular meeting of the Board attended, up to a
maximum of $10,000 during the year. Beginning in fiscal 1998, directors who are
not officers of the Company will receive an annual retainer of $10,000, payable
quarterly, and $1,250 for each meeting of the Board attended. Directors are
reimbursed for travel and other expenses. Officers who also serve as directors
do not receive fees for serving as directors.
 
     During fiscal year 1997, each director who was not an officer of the
Company was granted an option for 20,000 shares (10,000 shares pre-split) at an
exercise price of $30.63 ($61.25 pre-split) per share under the Company's 1992
Nonstatutory Stock Option Plan (the "1992 NSO Plan"). During fiscal year 1998,
each director who is not an officer will receive ten-year non-qualified options
under the 1992 NSO Plan to purchase 15,000 shares of Common Stock, options for
3,750 shares granted on the first day of each quarter, at an exercise price
equal to the market price on the date of grant.

     During fiscal 1997, the Compensation Committee was composed of Aubrey K.
McClendon, Tom L. Ward, E.F. Heizer, Jr. and Frederick B. Whittemore. Mr.

     Messrs. McClendon and Ward administer the Company's 1992 stock options
plans. The grant of new options under the 1992 Incentive Stock Option Plan (the

the 1992 NSO Plan during fiscal 1997 were those to the Company's non-employee

     Legal Counsel. Shannon T. Self, a director of the Company, is a shareholder
in the law firm of Self, Giddens & Lees, Inc., which provides legal services to
the Company. During fiscal 1997, the firm billed the Company approximately
$207,000 for such legal services.
 
     Oil and Gas Operations. Prior to 1989, Messrs. McClendon and Ward and their
affiliates, as independent oil producers, acquired various leasehold and working
interests. In 1989, Chesapeake Operating, Inc. ("COI"), a wholly-owned
subsidiary of the Company, was formed to drill and operate wells in which
Messrs. McClendon and Ward or their affiliates owned working interests. COI
entered into joint operating agreements with Messrs. McClendon and Ward and
other working interest owners and billed each for their respective shares of
expenses and fees.
 
     COI continues to operate wells in which directors, executive officers and
related parties own working interests. In addition, directors, executive
officers and related parties have acquired working interests directly and
indirectly from the Company and participated in wells drilled by COI on terms no
less favorable to the

Company than available to unrelated parties. Other than interests owned prior to
the Company's initial public offering in 1993, the Company's directors who are
not officers have not acquired from the Company interests in any new wells
drilled by the Company since their election as directors and have no present
intention to acquire interests in any new wells of the Company. The table below
presents information about drilling, completion, equipping and operating costs
billed to the person named from July 1, 1996 to June 30, 1997, the largest
amount owed by them during the period and the balance owed at July 1, 1996 and
June 30, 1997. No interest is charged on amounts owing for such costs, unless
such costs are not paid in a timely manner. The amounts for all other directors,
executive officers and related parties were insignificant.

                              EMPLOYMENT AGREEMENT

         THIS AGREEMENT is made effective July 1, 1997, between CHESAPEAKE
ENERGY CORPORATION, an Oklahoma corporation (the "Company"), and AUBREY K.
McCLENDON, an individual (the "Executive") and replaces and supersedes that
certain Employment Agreement between Company and Executive dated July 1, 1995.

                              W I T N E S S E T H:

         WHEREAS, the Company desires to retain the services of the Executive
and the Executive desires to make the Executive's services available to the
Company.

         NOW, THEREFORE, in consideration of the mutual promises herein
contained, the Company and the Executive agree as follows:

1.       Employment.  The Company hereby employs the Executive and the
Executive hereby accepts such employment subject to the terms and conditions
contained in this Agreement.  The Executive is engaged as an employee of the
Company, and the Executive and the Company do not intend to create a joint
venture, partnership or other relationship which might impose a fiduciary
obligation on the Executive or the Company in the performance of this
Agreement.

2.       Executive's Duties.  The Executive is employed on a full-time basis.
Throughout the term of this Agreement, the Executive will use the Executive's
best efforts and due diligence to assist the Company in achieving the most
profitable operation of the Company and the Company's affiliated entities
consistent with developing and maintaining a quality business operation.

         2.1     Specific Duties.  The Executive will serve as Chairman of the
                 Board and Chief Executive Officer for the Company.  From time
                 to time, the Executive may be appointed as an officer of one
                 (1) or more of the Company's subsidiaries. During the term of
                 this Agreement, the Executive will be nominated for election
                 or appointed to serve as a director of the Company and one (1)
                 or more of the Company's subsidiaries.  The Executive will
                 perform all of the services required to fully and faithfully
                 execute the office and position to which the Executive is
                 appointed and such other services as may be reasonably
                 directed by the board of directors of the Company.

         2.2     Modifications.  The precise duties to be performed by the
                 Executive may be extended or curtailed in the discretion of
                 the respective boards of directors of the Company.  However,
                 except for termination for cause under paragraph 6.1.2 of this
                 Agreement, the failure of the Executive to be elected, be
                 reelected or serve as a director of the Company during the
                 term of this Agreement, the

                                      1

<PAGE>   5
                 removal of the Executive as a member of the board of directors
                 of the Company, the withdrawal of the designation of the
                 Executive as Chairman of the Board or Chief Executive Officer
                 of the Company, or the assignment of the performance of duties
                 incumbent on the foregoing offices to other persons without
                 the prior written consent of the Executive will constitute
                 termination without cause by the Company.

         2.3     Rules and Regulations.  The Company currently has an
                 Employment Policies Manual which addresses frequently asked
                 questions regarding the Company. The Executive agrees to
                 comply with the Employment Policies Manual except to the
                 extent inconsistent with this Agreement.  The Employment
                 Policies Manual is subject to change without notice in the
                 sole discretion of the Company at any time.

         2.4     Stock Investment. For each calendar year during which this
                 Agreement is in effect, the Executive agrees to hold shares of
                 the Company's common stock having aggregate Investment Value
                 equal to five hundred percent (500%) of the compensation paid
                 to the Executive under paragraphs 4.1 and 4.2 of this
                 Agreement during such calendar year.  For purposes of this
                 section, the "Investment Value" of each share of stock will be
                 the higher of either (a) the price paid by the Executive for
                 such share as part of an open market purchase; or (b) the fair
                 market value on the date of exercise for shares acquired
                 through the exercise of employee stock options.  Any shares of
                 common stock acquired by the Executive prior to the date of
                 this Agreement and still owned by the Executive during the
                 term of this Agreement may be used to satisfy this requirement
                 to acquire common stock.  The Investment Value for previously
                 acquired stock shall be calculated using the average stock
                 price during the first six months of this Agreement.

                 The stock acquired or owned pursuant to this paragraph 2.4
                 must be held by the Executive at all times during the
                 Executive's employment by the Company or the Company's
                 affiliated entities.  In order to administer this provision,
                 the Executive agrees to return to the Company's Chief
                 Executive Officer a semi-annual report of purchases and
                 ownership in a form prepared by the Company.  This paragraph
                 will become null and void if the Company's common stock ceases
                 to be listed on the New York Stock Exchange or on the National
                 Association of Securities Dealers Automated Quotation System.
                 The Company has no obligation to sell or to purchase from the
                 Executive any of the Company's stock in connection with this
                 paragraph 2.4 and has made no representations or warranties
                 regarding the Company's stock, operations or financial
                 condition.

3.   Other Activities.  Except for the activities (the "Permitted Activities")
expressly permitted by paragraphs 3.1 and 3.2 of this Agreement, or the prior
written approval of the board of directors of the Company, the Executive will
not: (a) engage in business independent of the



                                      2
<PAGE>   6
Executive's employment by the Company which requires any substantial portion of
the Executive's time; (b) serve as an officer, general partner or member in any
corporation, partnership, company, or firm; (c) directly or indirectly invest
in, participate in or acquire an interest in any oil and gas business,
including, without limitation, (i) producing oil and gas,  (ii) drilling,
owning or operating oil and gas leases or wells, (iii) providing services or
materials to the oil and gas industry, (iv) marketing or refining oil or gas,
or (v) owning any interest in any corporation, partnership, company or entity
which conducts any of the foregoing activities.  The limitation in this
paragraph 3 will not prohibit an investment by the Executive in publicly traded
securities.  Notwithstanding the foregoing, the Executive will be permitted to
participate in the following activities which will be deemed to be approved by
the Company, if such activities are undertaken in strict compliance with this
Agreement.

         3.1     Company's Activities.  The Executive or the Executive's
                 designated affiliate will be permitted to acquire a working
                 interest in all of the wells spudded by the Company or the
                 Company's subsidiary corporations, partnerships or entities
                 (the "Program Wells") during any Calendar Quarter (as
                 hereafter defined) on the terms and conditions set forth
                 herein.  The Program Wells include any well spudded during
                 such Calendar Quarter in which the Company or the Company's
                 subsidiary corporations, partnerships or entities participate
                 as a nonoperator.

                 3.1.1    Amount of Participation.  On or before the date which
                          is thirty (30) days before the first (st) day of each
                          Calendar Quarter, the Executive will provide notice
                          to the compensation committee of the Company's board
                          of directors of the Executive's intent to participate
                          in the Program Wells during the succeeding Calendar
                          Quarter and the approximate percentage working
                          interest which the Executive proposes to participate
                          with during such Calendar Quarter.  The Executive's
                          percentage working interest in the Program Wells
                          spudded during such Calendar Quarter will be subject
                          to approval by the disinterested members of the
                          compensation committee of the Company's board of
                          directors and to the limitations set forth herein
                          (the "Approved Percentage").  The Executive's
                          Approved Percentage working Interest participation
                          (determined without consideration of any carried
                          interest) in the Program Wells for any Calendar
                          Quarter will not exceed two and one-half percent
                          (2.5%) on an eight-eighths (8/8ths) basis.  On
                          designation of the Approved Percentage for a Calendar
                          Quarter, the Executive will be deemed to have elected
                          to participate in each Program Well spudded during
                          such calendar Quarter with a working interest equal
                          to the following applicable percentage determined on
                          a well-by-well basis (the "Minimum Participation"):
                          (a) the Approved Percentage for a Program Well which
                          does not fall within clause (b) of this paragraph
                          3.1.1 or an Operations Well; or (b) zero percent (0%)
                          if the combined participation in the Program Well by
                          the Executive, Mr. Tom L. Ward and Mr. Marcus C.
                          Rowland with such individuals'


                                      3
<PAGE>   7
                          Approved Percentage under their respective employment
                          agreements causes the Company's working interest
                          (determined without consideration of any carried
                          interest) on the spud date for such Program Well to
                          be less than twelve and one-half percent (12.5%) on
                          an eight-eighths (8/8ths) basis.  If clause (b) of
                          this paragraph 3.1.1 prohibits the Executive's
                          participation in a Program Well, then Messrs. Ward
                          and Rowland will not be entitled to participate in
                          such Program Well under their employment agreements.
                          An "Operations Well" means a Program Well which falls
                          within the provisions of clause (b) of this paragraph
                          3.1.1, but for which the Executive's participation is
                          deemed necessary for the Company to retain operations
                          as determined by the disinterested members of the
                          compensation committee of the Company's board of
                          directors.  If the Executive fails to provide notice
                          of the Executive's intent to participate and the
                          Executive's proposed participation prior to the
                          specified date as provided herein, the amount of the
                          Approved Percentage for the Calendar Quarter will be
                          deemed to be zero (0).

                 3.1.2    Conditions of Participation.    The Participation by
                          the Executive in each Program Well will be on no
                          better terms than the terms agreed to by unaffiliated
                          third party participants in connection with the
                          acquisition of an interest in such Program Well from
                          the Company or its subsidiary corporations,
                          partnerships or entities.  The Approved Percentage
                          cannot be changed during any Calendar Quarter without
                          the prior approval of the disinterested members of
                          the compensation committee of the Company's board of
                          directors.  Any participation by the Executive under
                          this paragraph 3.1 is also conditioned upon the
                          Executive's participation in each Program Well
                          spudded during such Calendar Quarter in an amount
                          equal to the Minimum Participation.  The Executive
                          hereby agrees to execute and deliver any documents
                          reasonably requested by the Company and hereby
                          appoints the Company as the Executive's agent and
                          attorney-in-fact to execute and deliver such
                          documents if the Executive fails or refuses to
                          execute such documents.  The Executive further agrees
                          to pay all joint interest billings within one hundred
                          fifty (150) days after receipt.  For purposes of this
                          Agreement, the term "Calendar Quarter" means the
                          three (3) month periods commencing on the first (1st)
                          day of January, April, July and October.

         3.2     Other Activities.  The Executive currently conducts oil and
                 gas investment activities individually and through Chesapeake
                 Investments, an Oklahoma Limited Partnership ("Investments"),
                 Chesapeake Production Company, an Oklahoma corporation
                 ("Production"), and Chesapeake/Wood Joint Venture ("Venture").
                 The Executive will be permitted to continue oil and gas
                 activities in such entities but only to the extent such
                 activities are conducted on oil and


                                      4

                 gas leases or interests owned by the Executive, Investments,
                 Production or Venture as of July 1, 1995, or acquired by
                 Investments, production or Venture from the Company.  The
                 interests acquired by Investments shall be limited by the
                 provisions of paragraph 3.1 of this Agreement.  The Company
                 also consents to the Executive serving on the Board of
                 Directors of American Bank and Trust Company, located in
                 Edmond, OK.

4.       Executive's Compensation.  The Company agrees to compensate the
         Executive as follows:

         4.1     Base Salary.  A base salary (the "Base Salary"), at the
                 initial annual rate of not less than Three Hundred Thousand
                 Dollars ($300,000.00), will be paid to the Executive in equal
                 semi-monthly installments beginning July 15, 1997 during the
                 term of this Agreement.

         4.2     Bonus.  In addition to the Base Salary described at paragraph
                 4.1 of this Agreement, the Company may periodically pay bonus
                 compensation to the Executive.  Any bonus compensation will be
                 at the absolute discretion of the Company in such amounts and
                 at such times as the board of directors of the Company may
                 determine.

         4.3     Stock Options.  In addition to the compensation set forth in
                 paragraphs 4.1 and 4.2 of this Agreement, the Executive may

                 Company's various stock option plans, subject to the terms and
                 conditions thereof.

         4.4     Benefits.  The Company will provide the Executive such
                 retirement benefits, reimbursement of reasonable expenditures
                 for dues, travel and entertainment and such other benefits as
                 are customarily provided by the Company and as are set forth
                 in the Company's Employment Policies Manual.  The Company will
                 also provide the Executive the opportunity to apply for
                 coverage under the Company's medical, life and disability
                 plans, if any.  If the Executive is accepted for coverage
                 under such plans, the Company will provide such coverage on
                 the same terms as is customarily provided by the Company to
                 the plan participants as modified from time to time.  The
                 following specific benefits will also be provided to the
                 Executive at the expense of the Company:

                          three (3) weeks of paid vacation each twelve months
                          during the term of this Agreement.  No additional
                          compensation will be paid for failure to take
                          vacation and no vacation may be carried forward from

                          and/or country club in the Oklahoma City area as the
                          Executive may select; and (b) the reasonable cost of
                          any qualified business entertainment at such country
                          club.  All other costs, including, without implied
                          limitation, any initiation costs, initial membership
                          costs, personal use and business entertainment
                          unrelated to the Company will be the sole obligation
                          of the Executive and the Company will have no
                          liability with respect to such amounts.

                 4.4.3    Compensation Review.  The compensation of the
                          Executive will be reviewed not less frequently than
                          annually by the board of directors of the Company.
                          The compensation of the Executive prescribed by
                          paragraph 4 of this Agreement may be increased at the
                          discretion of the Company, but may not be reduced
                          without the prior written consent of the Executive.

                 4.4.4    Automobile and Travel Allowance.  The Executive will
                          receive a monthly cash allowance in the amount of One
                          Thousand Five Hundred Dollars ($1,500.00) to defer a
                          portion of the Executive's cost of acquiring,
                          operating and maintaining an automobile for use in
                          the Executive's employment.  Additionally, the
                          Executive will be entitled to utilize any aircraft
                          owned by the Company (whether in whole or in part)
                          for personal use and will not be required to
                          reimburse the Company for any cost related to such
                          use or pay any cost or charge with respect to such
                          use up to an amount during any fiscal year equal to
                          the Aircraft Allowance. For purposes of this
                          Agreement the term "Aircraft Allowance" means the
                          variable costs directly identifiable with each use
                          (including fuel, pilot charges, landing fees, hourly
                          charges under co-ownership arrangements and other
                          such costs) but specifically excluding any fixed
                          costs of the aircraft (including acquisition costs
                          and depreciation) and will be equal to $40,000.00 for
                          the Company's fiscal year ending on June 30, 1997,
                          and $50,000.00 for each fiscal year thereafter during
                          the term of this Agreement.  If the Executive's use
                          of the Company's aircraft exceeds the Aircraft
                          Allowance during any fiscal year the Executive will
                          be required to reimburse the Company for the variable
                          costs directly identified with each such use.

                 4.4.5    Accounting Support.  The Executive will be permitted
                          to utilize the Company's office space, computer
                          facilities and the equivalent of one (1) full-time
                          accounting employee (presently Linda Peterburs) of
                          the Company to maintain books and records for the
                          Executive and the Executive's Permitted Activities.
                          The Executive will not be required to pay any
                          compensation to the Company in connection with such
                          accounting services.

5.       Term.  In the absence of termination as set forth in paragraph 6
below, this Agreement will extend for a term of three (3) years commencing on
July 1, 1997, and ending on June 30, 2000 (the "Expiration Date").  Unless the
Company provides thirty (30) days prior written notice of nonextension to the
Executive, on each June 30 during the term of this Agreement, the term will be
automatically extended for one (1) additional year so that the remaining term
on this Agreement will be not less than two (2) and not more than three (3)
years.

6.       Termination.  This Agreement will continue in effect until the
expiration of the term stated at paragraph 5 of this Agreement unless earlier
terminated pursuant to this paragraph 6.

         6.1       Termination by Company.  The Company will have the following
                   rights to terminate this Agreement:

                   6.1.1       Termination without Cause.  The Company may
                               terminate this Agreement without cause at any
                               time by the service of written notice of
                               termination to the Executive specifying an
                               effective date of such termination not sooner
                               than sixty (60) business days after the date of
                               such notice (the "Termination Date").  In the
                               event the Executive is terminated without cause,
                               the Executive will receive as termination
                               compensation: (a) continuation of the Base
                               Salary provided by paragraph 4.1 during the
                               portion of the contract period remaining after
                               the date of the Executive's termination, but in
                               any event, through the Expiration Date; (b) any
                               benefits payable by operation of paragraph 4.4
                               of this Agreement during the portion of the
                               contract period remaining after the date of the
                               Executive's termination, but in any event,
                               through the Expiration Date; and (c) any
                               vacation pay accrued through the Termination
                               Date.  The termination compensation in (a) shall
                               be paid only if the Executive executes the
                               Company's standard termination agreement
                               releasing all legally waivable claims arising
                               from the Executive's employment.

                   6.1.2       Termination for Cause.  The Company may
                               terminate this Agreement for cause if the
                               Executive: (a) misappropriates the property of
                               the Company or commits any other act of
                               dishonesty; (b) engages in personal misconduct
                               which materially injures the Company; (c)
                               willfully violates any law or regulation
                               relating to the business of the Company which
                               results in injury to the Company; or (d)
                               willfully and repeatedly fails to perform the
                               Executive's duties hereunder.  In the event this
                               Agreement is terminated for cause, the Company
                               will not have any obligation to provide any
                               further payments or benefits to the Executive
                               after the effective date of such termination.
                               This Agreement will not be deemed to have
                               terminated for cause unless a written
                               determination specifying the


                                      7
<PAGE>   11
                               reasons for such termination is made, approved
                               by a majority of the disinterested members of
                               the board of directors of the Company and
                               delivered to the Executive.  Thereafter, the
                               Executive will have the right for a period of
                               twenty (20) days to request a board of directors
                               meeting to be held at a mutually agreeable time
                               and location within thirty (30) days, at which
                               meeting the Executive will have an opportunity
                               to be heard.  Failing such determination and
                               opportunity for hearing, any termination of this
                               Agreement will be deemed to have occurred
                               without cause.

                   6.1.3       Termination After Change in Control.  If, during
                               the term of this Agreement, there is a "Change
                               of Control" and within one (1) year thereafter:
                               (a) this Agreement expires and is not extended;
                               or (b) the Executive is terminated other than
                               under paragraphs 6.1.2, 6.3 or 6.4 based on
                               adequate grounds; or (c) the Executive resigns
                               as a result of a reassignment of duties
                               inconsistent with the Executive's position, a
                               reduction in the Executive's then current
                               compensation under paragraph 4 of this
                               Agreement, or a required relocation more than 25
                               miles from the Executive's then current place of
                               employment, then the Executive will be entitled
                               to a severance payment (in addition to any other
                               amounts payable to the Executive under this
                               Agreement or otherwise) in an amount equal to
                               thirty six (36) months of Base Salary as set
                               forth in paragraph 4.1 of this Agreement.  The
                               term "Change of Control" means any action of a
                               nature that would be required to be reported in
                               response to Item 6(e) of Schedule 14A of
                               Regulation 14A under the Securities Exchange Act
                               of 1934 with respect to the Company including,
                               without limitation (i) the direct or indirect
                               acquisition by any person after the date hereof
                               of beneficial ownership of the right to vote or
                               securities of the Company representing the right
                               to vote thirty five percent (35%) or more of the
                               combined voting power of the Company's then
                               outstanding securities having the right to vote
                               for the election of directors, or (ii) within
                               two years of a tender offer or exchange offer
                               for the voting stock of the Company or as a
                               result of a merger, consolidation, sale of
                               assets or contested election (or any combination
                               of the foregoing), a majority of the members of
                               the Company's board of directors is replaced by
                               directors who were not nominated and approved by
                               the board of directors.

         6.2       Termination by Executive.  The Executive may voluntarily
                   terminate this Agreement with or without cause by the
                   service of written notice of such termination to the Company
                   specifying an effective date of such termination sixty (60)
                   days after the date of such notice, during which time
                   Executive may use remaining accrued vacation days, or at the
                   Company's option, be paid for such days.  In the event this
                   Agreement is terminated by the Executive,


                                      8
<PAGE>   12
                   neither the Company nor the Executive will have any further
                   obligations hereunder including, without limitation, any
                   obligation of the Company to provide any further payments or
                   benefits to the Executive after the effective date of such
                   termination.

         6.3       Incapacity of Executive.  If the Executive suffers from a
                   physical or mental condition which in the reasonable
                   judgment of the Company's management prevents the Executive
                   in whole or in part from performing the duties specified
                   herein for a period of three (3) consecutive months, the
                   Executive may be terminated.  Although the termination shall
                   be deemed as a termination with cause, any compensation
                   payable under paragraph 4 of this Agreement will be
                   continued through the remaining contract period, but in any
                   event, through the Expiration Date.  Notwithstanding the
                   foregoing, the Executive's Base Salary specified in
                   paragraph 4.1 of this Agreement shall be reduced by any
                   benefits payable under any disability plans.

         6.4       Death of Executive.  If the Executive dies during the term
                   of this Agreement, the Company may thereafter terminate this
                   Agreement without compensation to the Executive's estate
                   except: (a) the obligation to continue the Base Salary
                   payments under paragraph 4.1 of this Agreement for twelve
                   (12) months and (b) the benefits described in paragraph 4.4
                   of this Agreement accrued through the effective date of such
                   termination.

         6.5       Effect of Termination.  The termination of this Agreement
                   will terminate all obligations of the Executive to render
                   services on behalf of the Company, provided that the
                   Executive will maintain the confidentiality of all
                   information acquired by the Executive during the term of his
                   employment in accordance with paragraph 7 of this Agreement.
                   Except as otherwise provided in paragraph 6 of this
                   Agreement, no accrued bonus, severance pay or other form of
                   compensation will be payable by the Company to the Executive
                   by reason of the termination of this Agreement.  All keys,
                   entry cards, credit cards, files, records, financial
                   information, furniture, furnishings, equipment, supplies and
                   other items relating to the Company will remain the property

                   any items remaining and to reassign the Executive's office
                   space after such date.  Prior to the effective date of
                   termination, the Executive will render such services to the
                   Company as might be reasonably required to provide for the
                   orderly termination of the Executive's employment.

7.       Confidentiality. The Executive recognizes that the nature of the
Executive's services are such that the Executive will have access to
information which constitutes trade secrets, is of a confidential nature, is of
great value to the Company or is the foundation on which the business of the
Company is predicated.  The Executive agrees not to disclose to any person
other than the Company's employees or the Company's legal counsel nor use for
any purpose, other than the performance of this Agreement, any confidential

Agreement, was available to the party to whom disclosed on a non-confidential
basis by disclosure or access provided by the Company or a third party, or was
otherwise developed or obtained independently by the person to whom disclosed

will be entitled to a copy of any Confidential Information in the possession of
the Executive. The Executive also agrees that the provisions of this paragraph
7 will survive the termination, expiration or cancellation of this Agreement
for a period of five (5) years.  The Executive will deliver to the Company all
originals and copies of the documents or materials containing Confidential
Information.  For purposes of paragraphs 7, 8, and 9 of this Agreement, the
Company expressly includes any of the Company's affiliated corporations,
partnerships or entities.

8.       Noncompetition.  For a period of twelve (12) months after Executive is
no longer employed by the Company as a result of either the resignation by the
Executive pursuant to paragraph 6.2 above, or Termination for Cause pursuant to
paragraph 6.1.2 above, Executive will not: (a) acquire, attempt to acquire or
aid another in the acquisition or attempted acquisition of an interest in oil
and gas assets, oil and gas production, oil and gas leases, mineral interests,
oil and gas wells or other such oil and gas exploration, development or
production activities within five (5) miles of any operations or ownership
interests of the Company or its affiliated corporations, partnerships or
entities, provided, however, this provision shall not apply to acquisitions
within said five (5) mile radius of assets or activities of a successor entity
resulting from a "Change in Control" as described in paragraph 6.1.3., which
assets were owned or activities were being conducted (1) prior to the date of
such Change in Control, or (2) after such Change in Control but for which the
Executive had no material responsibility; and; (b) for the Executive's own
account or for the benefit of another party solicit, induce, entice or attempt
to entice any employee, contractor, customer, vendor or subcontractor to
terminate or breach any relationship with the Company or the Company's
affiliates.  The Executive further agrees that the Executive

<PAGE>   14
will not circumvent or attempt to circumvent the foregoing agreements by any
future arrangement or through the actions of a third party.

9.       Proprietary Matters.  The Executive expressly understands and agrees
that any and all improvements, inventions, discoveries, processes or know-how
that are generated or conceived by the Executive during the term of this
Agreement, whether generated or conceived during the Executive's regular
working hours or otherwise, will be the sole and exclusive property of the
Company.  Whenever requested by the Company (either during the term of this
Agreement or thereafter), the Executive will assign or execute any and all
applications, assignments and or other instruments and do all things which the
Company deems necessary or appropriate in order to permit the Company to:  (a)
assign and convey or otherwise make available to the Company the sole and
exclusive right, title, and interest in and to said improvements, inventions,
discoveries, processes, know-how, applications, patents, copyrights, trade
names or trademarks; or (b) apply for, obtain, maintain, enforce and defend
patents, copyrights, trade names, or trademarks of the United States or of
foreign countries for said improvements, inventions, discoveries, processes or
know-how.  However, the improvements, inventions, discoveries, processes or
know-how generated or conceived by the Executive and referred to above (except
as they may be included in the patents, copyrights or registered trade names or
trademarks of the Company, or corporations, partnerships or other entities
which may be affiliated with the Company) shall not be exclusive property of
the Company at any time after having been disclosed or revealed or have
otherwise become available to the public or to a third party on a
non-confidential basis other than by a breach of this Agreement, or after they
have been independently developed or discussed without a breach of this
Agreement by a third party who has no obligation to the Company or its
affiliates.

10.      Arbitration.  The parties will attempt to promptly resolve any dispute
or controversy arising out of or relating to this Agreement or termination of
the Executive by the Company.  Any negotiations pursuant to this paragraph 10
are confidential and will be treated as compromise and settlement negotiations
for all purposes.  If the parties are unable to reach a settlement amicably,
the dispute will be submitted to binding arbitration before a single arbitrator
in accordance with the Employment Dispute Resolution Rules of the American
Arbitration Association.  The arbitrator will be instructed and empowered to
take reasonable steps to expedite the arbitration and the arbitrator's judgment
will be final and binding upon the parties subject solely to challenge on the
grounds of fraud or gross misconduct.  Except for damages arising out of a
breach of paragraphs 7, 8 or 9 of this Agreement, the arbitrator is not
empowered to award total damages (including compensatory damages) which exceed
300% of compensatory damages and each party hereby irrevocably waives any
damages in excess of that amount.  The arbitration will be held in Oklahoma
County, Oklahoma.  Judgment upon any verdict in arbitration may be entered in
any court of competent jurisdiction and the parties hereby consent to the
jurisdiction of, and proper venue in, the federal and state courts located in
Oklahoma County, Oklahoma.  Each party will bear its own costs in connection
with the arbitration and the costs of the arbitrator will be borne by the party
who the arbitrator determines did not prevail in the matter.  Unless otherwise
expressly set forth in this Agreement, the procedures specified in this
paragraph 10 will be


                                     11
<PAGE>   15
the sole and exclusive procedures for the resolution of disputes and
controversies between the parties arising out of or relating to this Agreement.
Notwithstanding the foregoing, a party may seek a preliminary injunction or
other provisional judicial relief if in such party's judgment such action is
necessary to avoid irreparable damage or to preserve the status quo.


11.      Miscellaneous.  The parties further agree as follows:

                              EMPLOYMENT AGREEMENT

         THIS AGREEMENT is made effective July 1, 1997, between CHESAPEAKE
ENERGY CORPORATION, an Oklahoma corporation (the "Company"), and TOM L. WARD,
an individual (the "Executive") and replaces and supersedes that certain
Employment Agreement between Company and Executive dated July 1, 1995.

                             W I T N E S S S E T H:

         WHEREAS, the Company desires to retain the services of the Executive
and the Executive desires to make the Executive's services available to the
Company.

         NOW, THEREFORE, in consideration of the mutual promises herein
contained, the Company and the Executive agree as follows:

1.       Employment.  The Company hereby employs the Executive and the
Executive hereby accepts such employment subject to the terms and conditions
contained in this Agreement.  The Executive is engaged as an employee of the
Company, and the Executive and the Company do not intend to create a joint
venture, partnership or other relationship which might impose a fiduciary
obligation on the Executive or the Company in the performance of this
Agreement.

2.       Executive's Duties.  The Executive is employed on a full-time basis.
Throughout the term of this Agreement, the Executive will use the Executive's
best efforts and due diligence to assist the Company in achieving the most
profitable operation of the Company and the Company's affiliated entities
consistent with developing and maintaining a quality business operation.

         2.1     Specific Duties.  The Executive will serve as President and
                 Chief Operating Officer for the Company.  From time to time,
                 the Executive may be appointed as an officer of one (1) or
                 more of the Company's subsidiaries. During the term of this
                 Agreement, the Executive will be nominated for election or
                 appointed to serve as a director of the Company and one (1) or
                 more of the Company's subsidiaries.  The Executive will
                 perform all of the services required to fully and faithfully
                 execute the office and position to which the Executive is
                 appointed and such other services as may be reasonably
                 directed by the board of directors of the Company.

         2.2     Modifications.  The precise duties to be performed by the
                 Executive may be extended or curtailed in the discretion of
                 the respective boards of directors of the Company.  However,
                 except for termination for cause under paragraph 6.1.2 of this
                 Agreement, the failure of the Executive to be elected, be
                 reelected or serve as a director of the Company during the
                 term of this Agreement, the





                                       1
<PAGE>   5
                 removal of the Executive as a member of the board of directors
                 of the Company, the withdrawal of the designation of the
                 Executive as President and Chief Operating Officer of the
                 Company, or the assignment of the performance of duties
                 incumbent on the foregoing offices to other persons without
                 the prior written consent of the Executive will constitute
                 termination without cause by the Company.

         2.3     Rules and Regulations.  The Company currently has an
                 Employment Policies Manual which addresses frequently asked
                 questions regarding the Company. The Executive agrees to
                 comply with the Employment Policies Manual except to the
                 extent inconsistent with this Agreement.  The Employment
                 Policies Manual is subject to change without notice in the
                 sole discretion of the Company at any time.

         2.4     Stock Investment. For each calendar year during which this
                 Agreement is in effect, the Executive agrees to hold shares of
                 the Company's common stock having aggregate Investment Value
                 equal to five hundred percent (500%) of the compensation paid
                 to the Executive under paragraphs 4.1 and 4.2 of this
                 Agreement during such calendar year.  For purposes of this
                 section, the "Investment Value" of each share of stock will be
                 the higher of either (a) the price paid by the Executive for
                 such share as part of an open market purchase; or (b) the fair
                 market value on the date of exercise for shares acquired
                 through the exercise of employee stock options.  Any shares of
                 common stock acquired by the Executive prior to the date of
                 this Agreement and still owned by the Executive during the
                 term of this Agreement may be used to satisfy this requirement
                 to acquire common stock.  The Investment Value for previously
                 acquired stock shall be calculated using the average stock
                 price during the first six months of this Agreement.

                 The stock acquired or owned pursuant to this paragraph 2.4
                 must be held by the Executive at all times during the
                 Executive's employment by the Company or the Company's
                 affiliated entities.  In order to administer this provision,
                 the Executive agrees to return to the Company's Chief
                 Executive Officer a semi-annual report of purchases and
                 ownership in a form prepared by the Company.  This paragraph
                 will become null and void if the Company's common stock ceases
                 to be listed on the New York Stock Exchange or on the National
                 Association of Securities Dealers Automated Quotation System.
                 The Company has no obligation to sell or to purchase from the
                 Executive any of the Company's stock in connection with this
                 paragraph 2.4 and has made no representations or warranties
                 regarding the Company's stock, operations or financial
                 condition.

3.   Other Activities.  Except for the activities (the "Permitted Activities")
expressly permitted by paragraphs 3.1 and 3.2 of this Agreement, or the prior
written approval of the board of directors of the Company, the Executive will
not: (a) engage in business independent of the





                                       2
<PAGE>   6
Executive's employment by the Company which requires any substantial portion of
the Executive's time; (b) serve as an officer, general partner or member in any
corporation, partnership, company, or firm; (c) directly or indirectly invest
in, participate in or acquire an interest in any oil and gas business,
including, without limitation, (i) producing oil and gas,  (ii) drilling, owning
or operating oil and gas leases or wells, (iii) providing services or materials
to the oil and gas industry, (iv) marketing or refining oil or gas, or (v)
owning any interest in any corporation, partnership, company or entity which
conducts any of the foregoing activities.  The limitation in this paragraph 3
will not prohibit an investment by the Executive in publicly traded securities. 
Notwithstanding the foregoing, the Executive will be permitted to participate in
the following activities which will be deemed to be approved by the Company, if
such activities are undertaken in strict compliance with this Agreement.

         3.1     Company's Activities.  The Executive or the Executive's
                 designated affiliate will be permitted to acquire a working
                 interest in all of the wells spudded by the Company or the
                 Company's subsidiary corporations, partnerships or entities
                 (the "Program Wells") during any Calendar Quarter (as
                 hereafter defined) on the terms and conditions set forth
                 herein.  The Program Wells include any well spudded during
                 such Calendar Quarter in which the Company or the Company's
                 subsidiary corporations, partnerships or entities participate
                 as a nonoperator.

                 3.1.1    Amount of Participation.  On or before the date which
                          is thirty (30) days before the first (1st) day of each
                          Calendar Quarter, the Executive will provide notice
                          to the compensation committee of the Company's board
                          of directors of the Executive's intent to participate
                          in the Program Wells during the succeeding Calendar
                          Quarter and the approximate percentage working
                          interest which the Executive proposes to participate
                          with during such Calendar Quarter.  The Executive's
                          percentage working interest in the Program Wells
                          spudded during such Calendar Quarter will be subject
                          to approval by the disinterested members of the
                          compensation committee of the Company's board of
                          directors and to the limitations set forth herein
                          (the "Approved Percentage").  The Executive's
                          Approved Percentage working Interest participation
                          (determined without consideration of any carried
                          interest) in the Program Wells for any Calendar
                          Quarter will not exceed two and one-half percent
                          (2.5%) on an eight-eighths (8/8ths) basis.  On
                          designation of the Approved Percentage for a Calendar
                          Quarter, the Executive will be deemed to have elected
                          to participate in each Program Well spudded during
                          such calendar Quarter with a working interest equal
                          to the following applicable percentage determined on
                          a well-by-well basis (the "Minimum Participation"):
                          (a) the Approved Percentage for a Program Well which
                          does not fall within clause (b) of this paragraph
                          3.1.1 or an Operations Well; or (b) zero percent (0%)
                          if the combined participation in the Program Well by
                          the Executive, Mr. Aubrey K.  McClendon and Mr.
                          Marcus C. Rowland with such





                                       3
<PAGE>   7
                          individuals' Approved Percentage under their
                          respective employment agreements causes the Company's
                          working interest (determined without consideration of
                          any carried interest) on the spud date for such
                          Program Well to be less than twelve and one-half
                          percent (12.5%) on an eight-eighths (8/8ths) basis.
                          If clause (b) of this paragraph 3.1.1 prohibits the
                          Executive's participation in a Program Well, then
                          Messrs. McClendon and Rowland will not be entitled to
                          participate in such Program Well under their
                          employment agreements.  An "Operations Well" means a
                          Program Well which falls within the provisions of
                          clause (b) of this paragraph 3.1.1, but for which the
                          Executive's participation is deemed necessary for the
                          Company to retain operations as determined by the
                          disinterested members of the compensation committee
                          of the Company's board of directors.  If the
                          Executive fails to provide notice of the Executive's
                          intent to participate and the Executive's proposed
                          participation prior to the specified date as provided
                          herein, the amount of the Approved Percentage for the
                          Calendar Quarter will be deemed to be zero (0).

                 3.1.2    Conditions of Participation.    The Participation by
                          the Executive in each Program Well will be on no
                          better terms than the terms agreed to by unaffiliated
                          third party participants in connection with the
                          acquisition of an interest in such Program Well from
                          the Company or its subsidiary corporations,
                          partnerships or entities.  The Approved Percentage
                          cannot be changed during any Calendar Quarter without
                          the prior approval of the disinterested members of
                          the compensation committee of the Company's board of
                          directors.  Any participation by the Executive under
                          this paragraph 3.1 is also conditioned upon the
                          Executive's participation in each Program Well
                          spudded during such Calendar Quarter in an amount
                          equal to the Minimum Participation.  The Executive
                          hereby agrees to execute and deliver any documents
                          reasonably requested by the Company and hereby
                          appoints the Company as the Executive's agent and
                          attorney-in-fact to execute and deliver such
                          documents if the Executive fails or refuses to
                          execute such documents.  The Executive further agrees
                          to pay all joint interest billings within one hundred
                          fifty (150) days after receipt.  For purposes of this
                          Agreement, the term "Calendar Quarter" means the
                          three (3) month periods commencing on the first (1st)
                          day of January, April, July and October.

         3.2     Other Activities.  The Executive currently conducts oil and
                 gas investment activities individually and through TLW
                 Production Company, an Oklahoma corporation ("Production"),
                 and TLW Investments, Inc., an Oklahoma corporation
                 ("Investments").  The Executive will be permitted to continue
                 oil and gas activities in such entities, but only to the
                 extent such activities are conducted on oil and gas leases or
                 interests owned by the Executive,





                                       4

                 Production or Investments as of July 1, 1995, or acquired by
                 Production or Investments from the Company.  The interests
                 acquired by Investments shall be limited by the provisions of
                 paragraph 3.1 of this Agreement.

4.       Executive's Compensation.  The Company agrees to compensate the
Executive as follows:

         4.1     Base Salary.  A base salary (the "Base Salary"), at the
                 initial annual rate of not less than Three Hundred Thousand
                 Dollars ($300,000.00), will be paid to the Executive in equal
                 semi-monthly installments beginning July 15, 1997 during the
                 term of this Agreement.

         4.2     Bonus.  In addition to the Base Salary described at paragraph
                 4.1 of this Agreement, the Company may periodically pay bonus
                 compensation to the Executive.  Any bonus compensation will be
                 at the absolute discretion of the Company in such amounts and
                 at such times as the board of directors of the Company may
                 determine.

         4.3     Stock Options.  In addition to the compensation set forth in
                 paragraphs 4.1 and 4.2 of this Agreement, the Executive may
                 periodically receive grants of stock options from the
                 Company's various stock option plans, subject to the terms and
                 conditions thereof.

         4.4     Benefits.  The Company will provide the Executive such
                 retirement benefits, reimbursement of reasonable expenditures
                 for dues, travel and entertainment and such other benefits as
                 are customarily provided by the Company and as are set forth
                 in the Company's Employment Policies Manual.  The Company will
                 also provide the Executive the opportunity to apply for
                 coverage under the Company's medical, life and disability
                 plans, if any.  If the Executive is accepted for coverage
                 under such plans, the Company will provide such coverage on
                 the same terms as is customarily provided by the Company to
                 the plan participants as modified from time to time.  The
                 following specific benefits will also be provided to the
                 Executive at the expense of the Company:

                          three (3) weeks of paid vacation each twelve months
                          during the term of this Agreement.  No additional
                          compensation will be paid for failure to take
                          vacation and no vacation may be carried forward from
                          one twelve month period to another.

                 4.4.2    Membership Dues. The Company will reimburse the
                          Executive for: (a) the monthly dues necessary to
                          maintain a full membership in a golf and/or country
                          club in the Oklahoma City area as the Executive may
                          select; and (b) the reasonable cost of any qualified
                          business entertainment at such country club.  All
                          other costs, including, without





                                       5

                          implied limitation, any initiation costs, initial
                          membership costs, personal use and business
                          entertainment unrelated to the Company will be the
                          sole obligation of the Executive and the Company will
                          have no liability with respect to such amounts.

                 4.4.3    Compensation Review.  The compensation of the
                          Executive will be reviewed not less frequently than
                          annually by the board of directors of the Company.
                          The compensation of the Executive prescribed by
                          paragraph 4 of this Agreement may be increased at the
                          discretion of the Company, but may not be reduced
                          without the prior written consent of the Executive.

                 4.4.4    Automobile and Travel Allowance.  The Executive will
                          receive a monthly cash allowance in the amount of One
                          Thousand Five Hundred Dollars ($1,500.00) to defer a
                          portion of the Executive's cost of acquiring,
                          operating and maintaining an automobile for use in
                          the Executive's employment.  Additionally, the
                          Executive will be entitled to utilize any aircraft
                          owned by the Company (whether in whole or in part)
                          for personal use and will not be required to
                          reimburse the Company for any cost related to such
                          use or pay any cost or charge with respect to such
                          use up to an amount during any fiscal year equal to
                          the Aircraft Allowance. For purposes of this
                          Agreement the term "Aircraft Allowance" means the
                          variable costs directly identifiable with each use
                          (including fuel, pilot charges, landing fees, hourly
                          charges under co-ownership arrangements and other
                          such costs) but specifically excluding any fixed
                          costs of the aircraft (including acquisition costs
                          and depreciation) and will be equal to $40,000.00 for
                          the Company's fiscal year ending on June 30, 1997,
                          and $50,000.00 for each fiscal year thereafter during
                          the term of this Agreement.  If the Executive's use
                          of the Company's aircraft exceeds the Aircraft
                          Allowance during any fiscal year the Executive will
                          be required to reimburse the Company for the variable
                          costs directly identified with each such use.

                 4.4.5    Accounting Support.  The Executive will be permitted
                          to utilize the Company's office space, computer
                          facilities and the equivalent of one (1) full-time
                          accounting employee (presently Cheryl Hamilton) of
                          the Company to maintain books and records for the
                          Executive and the Executive's Permitted Activities.
                          The Executive will not be required to pay any
                          compensation to the Company in connection with such
                          accounting services.

5.       Term.  In the absence of termination as set forth in paragraph 6
below, this Agreement will extend for a term of three (3) years commencing on
July 1, 1997, and ending on June 30, 2000 (the "Expiration Date").  Unless the
Company provides thirty (30) days prior written notice of nonextension to the
Executive, on each June 30 during the term of this





                                       6
<PAGE>   10
Agreement, the term will be automatically extended for one (1) additional year
so that the remaining term on this Agreement will be not less than two (2) and
not more than three (3) years.

6.       Termination.  This Agreement will continue in effect until the
expiration of the term stated at paragraph 5 of this Agreement unless earlier
terminated pursuant to this paragraph 6.

         6.1     Termination by Company.  The Company will have the following
                 rights to terminate this Agreement:

                 6.1.1    Termination without Cause.  The Company may terminate
                          this Agreement without cause at any time by the
                          service of written notice of termination to the
                          Executive specifying an effective date of such
                          termination not sooner than sixty (60) business days
                          after the date of such notice (the "Termination
                          Date").  In the event the Executive is terminated
                          without cause, the Executive will receive as
                          termination compensation: (a) continuation of the
                          Base Salary provided by paragraph 4.1 during the
                          portion of the contract period remaining after the
                          date of the Executive's termination, but in any
                          event, through the Expiration Date; (b) any benefits
                          payable by operation of paragraph 4.4 of this
                          Agreement during the portion of the contract period
                          remaining after the date of the Executive's
                          termination, but in any event, through the Expiration
                          Date; and (c) any vacation pay accrued through the
                          Termination Date.  The termination compensation in
                          (a) shall be paid only if the Executive executes the
                          Company's standard termination agreement releasing
                          all legally waivable claims arising from the
                          Executive's employment.

                 6.1.2    Termination for Cause.  The Company may terminate
                          this Agreement for cause if the Executive: (a)
                          misappropriates the property of the Company or
                          commits any other act of dishonesty; (b) engages in
                          personal misconduct which materially injures the
                          Company; (c) willfully violates any law or regulation
                          relating to the business of the Company which results
                          in injury to the Company; or (d) willfully and
                          repeatedly fails to perform the Executive's duties
                          hereunder.  In the event this Agreement is terminated
                          for cause, the Company will not have any obligation
                          to provide any further payments or benefits to the
                          Executive after the effective date of such
                          termination.  This Agreement will not be deemed to
                          have terminated for cause unless a written
                          determination specifying the reasons for such
                          termination is made, approved by a majority of the
                          disinterested members of the board of directors of
                          the Company and delivered to the Executive.
                          Thereafter, the Executive will have the right for a
                          period of twenty (20) days to request a board of





                                       7
<PAGE>   11
                          directors meeting to be held at a mutually agreeable
                          time and location within thirty (30) days, at which
                          meeting the Executive will have an opportunity to be
                          heard.  Failing such determination and opportunity
                          for hearing, any termination of this Agreement will
                          be deemed to have occurred without cause.

                 6.1.3    Termination After Change in Control.  If, during the
                          term of this Agreement, there is a "Change of
                          Control" and within one (1) year thereafter:  (a)
                          this Agreement expires and is not extended; or (b)
                          the Executive is terminated other than under
                          paragraphs 6.1.2, 6.3 or 6.4 based on adequate
                          grounds; or (c) the Executive resigns as a result of
                          a reassignment of duties inconsistent with the
                          Executive's position, a reduction in the Executive's
                          then current compensation under paragraph 4 of this
                          Agreement, or a required relocation more than 25
                          miles from the Executive's then current place of
                          employment, then the Executive will be entitled to a
                          severance payment (in addition to any other amounts
                          payable to the Executive under this Agreement or
                          otherwise) in an amount equal to thirty six (36)
                          months of Base Salary as set forth in paragraph 4.1
                          of this Agreement.  The term "Change of Control"
                          means any action of a nature that would be required
                          to be reported in response to Item 6(e) of Schedule
                          14A of Regulation 14A under the Securities Exchange
                          Act of 1934 with respect to the Company including,
                          without limitation (i) the direct or indirect
                          acquisition by any person after the date hereof of
                          beneficial ownership of the right to vote or
                          securities of the Company representing the right to
                          vote thirty five percent (35%) or more of the
                          combined voting power of the Company's then
                          outstanding securities having the right to vote for
                          the election of directors, or (ii) within two years
                          of a tender offer or exchange offer for the voting
                          stock of the Company or as a result of a merger,
                          consolidation, sale of assets or contested election
                          (or any combination of the foregoing), a majority of
                          the members of the Company's board of directors is
                          replaced by directors who were not nominated and
                          approved by the board of directors.

         6.2     Termination by Executive.  The Executive may voluntarily
                 terminate this Agreement with or without cause by the service
                 of written notice of such termination to the Company
                 specifying an effective date of such termination sixty (60)
                 days after the date of such notice, during which time
                 Executive may use remaining accrued vacation days, or at the
                 Company's option, be paid for such days.  In the event this
                 Agreement is terminated by the Executive, neither the Company
                 nor the Executive will have any further obligations hereunder
                 including, without limitation, any obligation of the Company
                 to provide any further payments or benefits to the Executive
                 after the effective date of such termination.





                                       8
<PAGE>   12
         6.3     Incapacity of Executive.  If the Executive suffers from a
                 physical or mental condition which in the reasonable judgment
                 of the Company's management prevents the Executive in whole or
                 in part from performing the duties specified herein for a
                 period of three (3) consecutive months, the Executive may be
                 terminated.  Although the termination shall be deemed as a
                 termination with cause, any compensation payable under
                 paragraph 4 of this Agreement will be continued through the
                 remaining contract period, but in any event, through the
                 Expiration Date.  Notwithstanding the foregoing, the
                 Executive's Base Salary specified in paragraph 4.1 of this
                 Agreement shall be reduced by any benefits payable under any
                 disability plans.

         6.4     Death of Executive.  If the Executive dies during the term of
                 this Agreement, the Company may thereafter terminate this
                 Agreement without compensation to the Executive's estate
                 except: (a) the obligation to continue the Base Salary
                 payments under paragraph 4.1 of this Agreement for twelve (12)
                 months and (b) the benefits described in paragraph 4.4 of this
                 Agreement accrued through the effective date of such
                 termination.

         6.5     Effect of Termination.  The termination of this Agreement will
                 terminate all obligations of the Executive to render services
                 on behalf of the Company, provided that the Executive will
                 maintain the confidentiality of all information acquired by
                 the Executive during the term of his employment in accordance
                 with paragraph 7 of this Agreement.  Except as otherwise
                 provided in paragraph 6 of this Agreement, no accrued bonus,
                 severance pay or other form of compensation will be payable by
                 the Company to the Executive by reason of the termination of
                 this Agreement.  All keys, entry cards, credit cards, files,
                 records, financial information, furniture, furnishings,
                 equipment, supplies and other items relating to the Company
                 will remain the property of the Company.  The Executive will
                 have the right to retain and remove all personal property and
                 effects which are owned by the Executive and located in the
                 offices of the Company.  All such personal items will be
                 removed from such offices no later than seven (7) days after
                 the effective date of termination, and the Company is hereby
                 authorized to discard any items remaining and to reassign the
                 Executive's office space after such date.  Prior to the
                 effective date of termination, the Executive will render such
                 services to the Company as might be reasonably required to
                 provide for the orderly termination of the Executive's
                 employment.


7.       Confidentiality. The Executive recognizes that the nature of the
Executive's services are such that the Executive will have access to
information which constitutes trade secrets, is of a confidential nature, is of
great value to the Company or is the foundation on which the business of the
Company is predicated.  The Executive agrees not to disclose to any person
other than the Company's employees or the Company's legal counsel nor use for
any





                                       9

purpose, other than the performance of this Agreement, any confidential
information ("Confidential Information").  Confidential Information includes
data or material (regardless of form) which is:  (a) a trade secret; (b)
provided, disclosed or delivered to Executive by the Company, any officer,
director, employee, agent, attorney, accountant, consultant, or other person or
entity employed by the Company in any capacity, any customer, borrower or
business associate of the Company or any public authority having jurisdiction
over the Company of any business activity conducted by the Company; or (c)
produced, developed, obtained or prepared by or on behalf of Executive or the
Company (whether or not such information was developed in the performance of
this Agreement) with respect to the Company or any assets oil and gas
prospects, business activities, officers, directors, employees, borrowers or
customers of the foregoing.  However, Confidential Information shall not
include any information, data or material which at the time of disclosure or
use was generally available to the public other than by a breach of this
Agreement, was available to the party to whom disclosed on a non-confidential
basis by disclosure or access provided by the Company or a third party, or was
otherwise developed or obtained independently by the person to whom disclosed
without a breach of this Agreement.  On request by the Company, the Company
will be entitled to a copy of any Confidential Information in the possession of
the Executive.  The Executive also agrees that the provisions of this paragraph
7 will survive the termination, expiration or cancellation of this Agreement
for a period of five (5) years.  The Executive will deliver to the Company all
originals and copies of the documents or materials containing Confidential
Information.  For purposes of paragraphs 7, 8, and 9 of this Agreement, the
Company expressly includes any of the Company's affiliated corporations,
partnerships or entities.

8.       Noncompetition.  For a period of twelve (12) months after Executive is
no longer employed by the Company as a result of either the resignation by the
Executive pursuant to paragraph 6.2 above, or Termination for Cause pursuant to
paragraph 6.1.2 above, Executive will not: (a) acquire, attempt to acquire or
aid another in the acquisition or attempted acquisition of an interest in oil
and gas assets, oil and gas production, oil and gas leases, mineral interests,
oil and gas wells or other such oil and gas exploration, development or
production activities within five (5) miles of any operations or ownership
interests of the Company or its affiliated corporations, partnerships or
entities, provided, however, this provision shall not apply to acquisitions
within said five (5) mile radius of assets or activities of a successor entity
resulting from a "Change in Control" as described in paragraph 6.1.3., which
assets were owned or activities were being conducted (1) prior to the date of
such Change in Control, or (2) after such Change in Control but for which the
Executive had no material responsibility; and; (b) for the Executive's own
account or for the benefit of another party solicit, induce, entice or attempt
to entice any employee, contractor, customer, vendor or subcontractor to
terminate or breach any relationship with the Company or the Company's
affiliates.  The Executive further agrees that the Executive will not
circumvent or attempt to circumvent the foregoing agreements by any future
arrangement or through the actions of a third party.

9.       Proprietary Matters.  The Executive expressly understands and agrees
that any and all improvements, inventions, discoveries, processes or know-how
that are generated or





                                       10

conceived by the Executive during the term of this Agreement, whether generated
or conceived during the Executive's regular working hours or otherwise, will be
the sole and exclusive property of the Company.  Whenever requested by the
Company (either during the term of this Agreement or thereafter), the Executive
will assign or execute any and all applications, assignments and or other
instruments and do all things which the Company deems necessary or appropriate
in order to permit the Company to:  (a) assign and convey or otherwise make
available to the Company the sole and exclusive right, title, and interest in
and to said improvements, inventions, discoveries, processes, know-how,
applications, patents, copyrights, trade names or trademarks; or (b) apply for,
obtain, maintain, enforce and defend patents, copyrights, trade names, or
trademarks of the United States or of foreign countries for said improvements,
inventions, discoveries, processes or know-how.  However, the improvements,
inventions, discoveries, processes or know-how generated or conceived by the
Executive and referred to above (except as they may be included in the patents,
copyrights or registered trade names or trademarks of the Company, or
corporations, partnerships or other entities which may be affiliated with the
Company) shall not be exclusive property of the Company at any time after
having been disclosed or revealed or have otherwise become available to the
public or to a third party on a non-confidential basis other than by a breach
of this Agreement, or after they have been independently developed or discussed
without a breach of this Agreement by a third party who has no obligation to
the Company or its affiliates.

10.      Arbitration.  The parties will attempt to promptly resolve any dispute
or controversy arising out of or relating to this Agreement or termination of
the Executive by the Company.  Any negotiations pursuant to this paragraph 10
are confidential and will be treated as compromise and settlement negotiations
for all purposes.  If the parties are unable to reach a settlement amicably,
the dispute will be submitted to binding arbitration before a single arbitrator
in accordance with the Employment Dispute Resolution Rules of the American
Arbitration Association.  The arbitrator will be instructed and empowered to
take reasonable steps to expedite the arbitration and the arbitrator's judgment
will be final and binding upon the parties subject solely to challenge on the
grounds of fraud or gross misconduct.  Except for damages arising out of a
breach of paragraphs 7, 8 or 9 of this Agreement, the arbitrator is not
empowered to award total damages (including compensatory damages) which exceed
300% of compensatory damages and each party hereby irrevocably waives any
damages in excess of that amount.  The arbitration will be held in Oklahoma
County, Oklahoma.  Judgment upon any verdict in arbitration may be entered in
any court of competent jurisdiction and the parties hereby consent to the
jurisdiction of, and proper venue in, the federal and state courts located in
Oklahoma County, Oklahoma.  Each party will bear its own costs in connection
with the arbitration and the costs of the arbitrator will be borne by the party
who the arbitrator determines did not prevail in the matter.  Unless otherwise
expressly set forth in this Agreement, the procedures specified in this
paragraph 10 will be the sole and exclusive procedures for the resolution of
disputes and controversies between the parties arising out of or relating to
this Agreement.  Notwithstanding the foregoing, a party may seek a preliminary
injunction or other provisional judicial relief if in such party's judgment
such action is necessary to avoid irreparable damage or to preserve the status
quo.

                 incurred by the successful party.

                 and the Executive, the relationship between the Company and
                 the Executive will be bound by the terms of this Agreement and
                 the Employment Policies Manual and not by any other agreements
                 or otherwise.  In the event of a conflict between the

                              EMPLOYMENT AGREEMENT

    THIS AGREEMENT is made effective July 1, 1997, between CHESAPEAKE ENERGY
CORPORATION, an Oklahoma corporation (the "Company"), and MARCUS C. ROWLAND, an
individual (the "Executive") and replaces and supersedes that certain
Employment Agreement between Company and Executive dated March 1, 1995.

                              W I T N E S S E T H:

    WHEREAS, the Company desires to retain the services of the Executive and
the Executive desires to make the Executive's services available to the
Company.

    NOW, THEREFORE, in consideration of the mutual promises herein contained,
the Company and the Executive agree as follows:

1.  Employment. The Company hereby employs the Executive and the Executive
hereby accepts such employment subject to the terms and conditions contained in
this Agreement. The Executive is engaged as an employee of the Company, and the
Executive and the Company do not intend to create a joint venture, partnership
or other relationship which might impose a fiduciary obligation on the
Executive or the Company in the performance of this Agreement.

2.  Executive's Duties. The Executive is employed on a full-time basis.
Throughout the term of this Agreement, the Executive will use the Executive's
best efforts and due diligence to assist the Company in achieving the most
profitable operation of the Company and the Company's affiliated entities
consistent with developing and maintaining a quality business operation.

    2.1  Specific Duties. The Executive will serve as Chief Financial Officer
         and Senior Vice President - Finance for the Company. The Executive
         will perform all of the services required to fully and faithfully
         execute the office and position to which the Executive is appointed
         and such other services as may be reasonably requested by the
         Executive's supervisor. During the term of this Agreement, the
         Executive may be nominated for election or appointed to serve as a
         director or officer of the Company's subsidiaries as determined in the
         board of directors' sole discretion.

    2.2  Supervision. The services of the Executive will be requested and
         directed by the Chief Executive Officer, Mr. Aubrey K. McClendon.

    2.3  Rules and Regulations. The Company currently has an Employment
         Policies Manual which addresses frequently asked questions regarding
         the Company. The Executive agrees to comply with the Employment
         Policies Manual except to the extent inconsistent with this Agreement.
         The Employment Policies





                                       1
<PAGE>   5
         Manual is subject to change without notice in the sole discretion of
         the Company at any time.

    2.4  Stock Investment. For each calendar year during which this Agreement
         is in effect, the Executive agrees to hold shares of the Company's
         common stock having aggregate Investment Value equal to one hundred
         percent (100%) of the compensation paid to the Executive under
         paragraphs 4.1 and 4.2 of this Agreement during such calendar year.
         For purposes of this section, the "Investment Value" of each share of
         stock will be the higher of either (a) the price paid by the Executive
         for such share as part of an open market purchase; or (b) the fair
         market value on the date of exercise for shares acquired through the
         exercise of employee stock options. Any shares of common stock
         acquired by the Executive prior to the date of this Agreement and
         still owned by the Executive during the term of this Agreement may be
         used to satisfy this requirement to acquire common stock. The
         Investment Value for previously acquired stock shall be calculated
         using the average stock price during the first six months of this
         Agreement.

         The stock acquired or owned pursuant to this paragraph 2.4 must be
         held by the Executive at all times during the Executive's employment
         by the Company or the Company's affiliated entities. In order to
         administer this provision, the Executive agrees to return to the
         Company's Chief Executive Officer a semi-annual report of purchases
         and ownership in a form prepared by the Company. This paragraph will
         become null and void if the Company's common stock ceases to be listed
         on the New York Stock Exchange or on the National Association of
         Securities Dealers Automated Quotation System. The Company has no
         obligation to sell or to purchase from the Executive any of the
         Company's stock in connection with this paragraph 2.4 and has made no
         representations or warranties regarding the Company's stock,
         operations or financial condition.

3.  Other Activities. Except for the activities (the "Permitted Activities")
expressly permitted by paragraphs 3.1 and 3.2 of this Agreement, or the prior
written approval of the board of directors of the Company, the Executive will

                                       2

permitted to participate in the following activities which will be deemed to be
approved by the Company, if such activities are undertaken in strict compliance
with this Agreement.

    3.1  Company's Activities. The Executive or the Executive's designated
         affiliate will be permitted to acquire a working interest in all of
         the wells spudded by the Company or the Company's subsidiary
         corporations, partnerships or entities (the "Program Wells") during
         any Calendar Quarter (as hereafter defined) on the terms and
         conditions set forth herein. The Program Wells include any well
         spudded during such Calendar Quarter in which the Company or the
         Company's subsidiary corporations, partnerships or entities
         participate as a nonoperator.

         3.1.1       Amount of Participation. On or before the date which is
                     thirty (30) days before the first (1st) day of each
                     Calendar Quarter, the Executive will provide notice to the
                     compensation committee of the Company's board of directors
                     of the Executive's intent to participate in the Program
                     Wells during the succeeding Calendar Quarter and the
                     approximate percentage working interest which the
                     Executive proposes to participate with during such
                     Calendar Quarter. The Executive's percentage working
                     interest in the Program Wells spudded during such Calendar
                     Quarter will be subject to approval by the disinterested
                     members of the compensation committee of the Company's
                     board of directors and to the limitations set forth herein
                     (the "Approved Percentage"). The Executive's Approved
                     Percentage working Interest participation (determined
                     without consideration of any carried interest) in the
                     Program Wells for any Calendar Quarter will not exceed one
                     percent (1.0%) on an eight-eighths (8/8ths) basis. On
                     designation of the Approved Percentage for a Calendar
                     Quarter, the Executive will be deemed to have elected to
                     participate in each Program Well spudded during such
                     calendar Quarter with a working interest equal to the
                     following applicable percentage determined on a well-by-
                     well basis (the "Minimum Participation"): (a) the Approved
                     Percentage for a Program Well which does not fall within
                     clause (b) of this paragraph 3.1.1 or an Operations Well;
                     or (b) zero percent (0%) if the combined participation in
                     the Program Well by the Executive, Mr. Tom L. Ward and Mr.
                     Aubrey K. McClendon with such individuals' Approved
                     Percentage under their respective employment agreements
                     causes the Company's working interest (determined without
                     consideration of any carried interest) on the spud date
                     for such Program Well to be less than twelve and one-half
                     percent (12.5%) on an eight-eighths (8/8ths) basis. If
                     clause (b) of this paragraph 3.1.1 prohibits the
                     Executive's participation in a Program Well, then Messrs.
                     Ward and McClendon will not be entitled to participate in
                     such Program Well under their employment agreements. An
                     "Operations Well" means a Program Well which falls within
                     the provisions of clause (b) of this paragraph 3.1.1, but
                     for which the





                                       3
<PAGE>   7
                     Executive's participation is deemed necessary for the
                     Company to retain operations as determined by the
                     disinterested members of the compensation committee of the
                     Company's board of directors. If the Executive fails to
                     provide notice of the Executive's intent to participate
                     and the Executive's proposed participation prior to the
                     specified date as provided herein, the amount of the
                     Approved Percentage for the Calendar Quarter will be
                     deemed to be zero (0).

             3.1.2   Conditions of Participation. The Participation by the
                     Executive in each Program Well will be on no better terms
                     than the terms agreed to by unaffiliated third party
                     participants in connection with the acquisition of an
                     interest in such Program Well from the Company or its
                     subsidiary corporations, partnerships or entities. The
                     Approved Percentage cannot be changed during any Calendar
                     Quarter without the prior approval of the disinterested
                     members of the compensation committee of the Company's
                     board of directors. Any participation by the Executive
                     under this paragraph 3.1 is also conditioned upon the
                     Executive's participation in each Program Well spudded
                     during such Calendar Quarter in an amount equal to the
                     Minimum Participation. The Executive hereby agrees to
                     execute and deliver any documents reasonably requested by
                     the Company and hereby appoints the Company as the
                     Executive's agent and attorney-in-fact to execute and
                     deliver such documents if the Executive fails or refuses
                     to execute such documents. The Executive further agrees to
                     pay all joint interest billings within one hundred twenty
                     (120) days after receipt. For purposes of this Agreement,
                     the term "Calendar Quarter" means the three (3) month
                     periods commencing on the first (1st) day of January,
                     April, July and October.

    3.2  Other Activities. The Executive currently conducts oil and gas
         investment activities individually and through MJ Partners, a Texas
         general partnership ("MJ"). The Executive will be permitted to 
         continue oil and gas activities in such entity, but only to the extent
         such activities are conducted on oil and gas leases or interests owned
         by the Executive or MJ as of March 1, 1993, or acquired pursuant to
         paragraph 3.1 of this Agreement.

4.  Executive's Compensation. The Company agrees to compensate the Executive as
follows:

    4.1  Base Salary. A base salary (the "Base Salary"), at the initial annual
         rate of not less than Two Hundred Twenty Five Thousand Dollars
         ($225,000.00), will be paid to the Executive in equal semi-monthly
         installments beginning July 15, 1997 during the term of this
         Agreement.





                                       4

    4.2  Bonus. In addition to the Base Salary described at paragraph 4.1 of
         this Agreement, the Company may periodically pay bonus compensation to
         the Executive. Any bonus compensation will be at the absolute
         discretion of the Company in such amounts and at such times as the
         board of directors of the Company may determine.

    4.3  Stock Options. In addition to the compensation set forth in paragraphs
         4.1 and 4.2 of this Agreement, the Executive may periodically receive
         grants of stock options from the Company's various stock option plans,
         subject to the terms and conditions thereof.

    4.4  Benefits. The Company will provide the Executive such retirement
         benefits, reimbursement of reasonable expenditures for dues, travel
         and entertainment and such other benefits as are customarily provided

         Policies Manual. The Company will also provide the Executive the
         opportunity to apply for coverage under the Company's medical, life
         and disability plans, if any. If the Executive is accepted for
         coverage under such plans, the Company will provide such coverage on
         the same terms as is customarily provided by the Company to the plan
         participants as modified from time to time. The following specific
         benefits will also be provided to the Executive at the expense of the
         Company:

         4.4.1   Vacation. The Executive will be entitled to take three (3)
                 weeks of paid vacation each twelve months during the term of
                 this Agreement. No additional compensation will be paid for
                 failure to take vacation and no vacation may be carried
                 forward from one twelve month period to another.

         4.4.2   Membership Dues. The Company will reimburse the Executive for:

                 in a country club in the Oklahoma City area selected by the
                 Executive; and (b) the reasonable cost of any qualified
                 business entertainment at such country club. All other costs,
                 including, without implied limitation, any initiation costs,
                 initial membership costs, personal use and business
                 entertainment unrelated to the Company will be the sole
                 obligation of the Executive and the Company will have no
                 liability with respect to such amounts.

         4.4.3   Compensation Review. The compensation of the Executive will be
                 reviewed not less frequently than annually by the board of
                 directors of the Company. The compensation of the Executive
                 prescribed by paragraph 4 of this Agreement may be increased
                 at the discretion of the Company, but may not be reduced
                 without the prior written consent of the Executive.

                 acquiring, operating and maintaining an automobile for use in
                 the Executive's employment.

5.  Term. In the absence of termination as set forth in paragraph 6 below, this
Agreement will extend for a term of three (3) years commencing on July 1, 1997,
and ending on June 30, 2000 (the "Expiration Date"). Unless the Company
provides thirty (30) days prior written notice of nonextension to the
Executive, on each June 30 during the term of this Agreement, the term will be
automatically extended for one (1) additional year so that the remaining term
on this Agreement will be not less than two (2) and not more than three (3)

6.  Termination. This Agreement will continue in effect until the expiration of
the term stated at paragraph 5 of this Agreement unless earlier terminated
pursuant to this paragraph 6.

                 Agreement without cause at any time by the service of written
                 notice of termination to the Executive specifying an effective
                 date of such termination not sooner than sixty (60) business
                 days after the date of such notice (the "Termination Date").
                 In the event the Executive is terminated without cause, the

                 continuation of the Base Salary provided by paragraph 4.1
                 during the portion of the contract period remaining after the

                 the Expiration Date; (b) any benefits payable by operation of
                 paragraph 4.4 of this Agreement during the portion of the

                 termination, but in any event, through the Expiration Date;
                 and (c) any vacation pay accrued through the Termination Date.
                 The termination compensation in (a) shall be paid only if the

                 agreement releasing all legally waivable claims arising from
                 the Executive's employment.

         6.1.2   Termination for Cause. The Company may terminate this
                 Agreement for cause if the Executive: (a) misappropriates the
                 property of the Company or commits any other act of
                 dishonesty; (b) engages in personal misconduct which
                 materially injures the Company; (c) willfully violates any law
                 or regulation relating to the business of the Company which

<PAGE>   10
                 hereunder. In the event this Agreement is terminated for
                 cause, the Company will not have any obligation to provide any
                 further payments or benefits to the Executive after the
                 effective date of such termination.

         6.1.3   Termination After Change in Control. If, during the term of
                 this Agreement, there is a "Change of Control" and within one
                 (1) year thereafter: (a) this Agreement expires and is not
                 extended; or (b) the Executive is terminated other than under
                 paragraphs 6.1.2, 6.3 or 6.4 based on adequate grounds; or (c)

                 Executive's then current compensation under paragraph 4 of
                 this Agreement, or a required relocation more than 25 miles
                 from the Executive's then current place of employment, then
                 the Executive will be entitled to a severance payment (in
                 addition to any other amounts payable to the Executive under
                 this Agreement or otherwise) in an amount equal to thirty six
                 (36) months of Base Salary as set forth in paragraph 4.1 of
                 this Agreement. The term "Change of Control" means any action
                 of a nature that would be required to be reported in response
                 to Item 6(e) of Schedule 14A of Regulation 14A under the
                 Securities Exchange Act of 1934 with respect to the Company
                 including, without limitation (i) the direct or indirect
                 acquisition by any person after the date hereof of beneficial
                 ownership of the right to vote or securities of the Company
                 representing the right to vote thirty five percent (35%) or
                 more of the combined voting power of the Company's then
                 outstanding securities having the right to vote for the
                 election of directors, or (ii) within two years of a tender
                 offer or exchange offer for the voting stock of the Company or
                 as a result of a merger, consolidation, sale of assets or
                 contested election (or any combination of the foregoing), a
                 majority of the members of the Company's board of directors is
                 replaced by directors who were not nominated and approved by
                 the board of directors.

    6.2  Termination by Executive. The Executive may voluntarily terminate this
         Agreement with or without cause by the service of written notice of
         such termination to the Company specifying an effective date of such
         termination sixty (60) days after the date of such notice, during
         which time Executive may use remaining accrued vacation days, or at
         the Company's option, be paid for such days. In the event this
         Agreement is terminated by the Executive, neither the Company nor the
         Executive will have any further obligations hereunder including,
         without limitation, any obligation of the Company to provide any
         further payments or benefits to the Executive after the effective date
         of such termination.





                                       7
<PAGE>   11
    6.3  Incapacity of Executive. If the Executive suffers from a physical or
         mental condition which in the reasonable judgment of the Company's
         management prevents the Executive in whole or in part from performing
         the duties specified herein for a period of three (3) consecutive
         months, the Executive may be terminated. Although the termination
         shall be deemed as a termination with cause, any compensation payable
         under paragraph 4 of this Agreement will be continued through the
         remaining contract period, but in any event, through the Expiration
         Date.  Notwithstanding the foregoing, the Executive's Base Salary
         specified in paragraph 4.1 of this Agreement shall be reduced by any
         benefits payable under any disability plans.

    6.4  Death of Executive. If the Executive dies during the term of this
         Agreement, the Company may thereafter terminate this Agreement without
         compensation to the Executive's estate except: (a) the obligation to
         continue the Base Salary payments under paragraph 4.1 of this
         Agreement for twelve (12) months and (b) the benefits described in
         paragraph 4.4 of this Agreement accrued through the effective date of
         such termination.

    6.5  Effect of Termination. The termination of this Agreement will
         terminate all obligations of the Executive to render services on
         behalf of the Company, provided that the Executive will maintain the
         confidentiality of all information acquired by the Executive during
         the term of his employment in accordance with paragraph 7 of this
         Agreement. Except as otherwise provided in paragraph 6 of this
         Agreement, no accrued bonus, severance pay or other form of
         compensation will be payable by the Company to the Executive by reason
         of the termination of this Agreement. All keys, entry cards, credit
         cards, files, records, financial information, furniture, furnishings,
         equipment, supplies and other items relating to the Company will
         remain the property of the Company. The Executive will have the right
         to retain and remove all personal property and effects which are owned
         by the Executive and located in the offices of the Company. All such
         personal items will be removed from such offices no later than two (2)
         days after the effective date of termination, and the Company is
         hereby authorized to discard any items remaining and to reassign the
         Executive's office space after such date. Prior to the effective date
         of termination, the Executive will render such services to the Company
         as might be reasonably required to provide for the orderly termination
         of the Executive's employment.


7.  Confidentiality. The Executive recognizes that the nature of the
Executive's services are such that the Executive will have access to
information which constitutes trade secrets, is of a confidential nature, is of
great value to the Company or is the foundation on which the business of the
Company is predicated. The Executive agrees not to disclose to any person other
than the Company's employees or the Company's legal counsel nor use for any
purpose, other than the performance of this Agreement, any confidential
information





                                       8
<PAGE>   12

("Confidential Information"). Confidential Information includes data or
material (regardless of form) which is: (a) a trade secret; (b) provided,       
disclosed or delivered to Executive by the Company, any officer, director,
employee, agent, attorney, accountant, consultant, or other person or entity
employed by the Company in any capacity, any customer, borrower or business
associate of the Company or any public authority having jurisdiction over the
Company of any business activity conducted by the Company; or (c) produced,
developed, obtained or prepared by or on behalf of Executive or the Company
