     This change of control agreement ("Agreement") is entered into effective as
of _________, ____, by and between Canaan Energy Corporation ("Canaan") and
_____________ ("Employee").

     WHEREAS, Canaan desires to retain certain key employee personnel and,
accordingly, the Board of Directors of Canaan has approved Canaan entering into

continued service to Canaan.

     NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, Canaan and Employee agree as follows:

1.   DEFINITIONS.
     -----------

     (a)  "Change in Duties" shall mean the occurrence, within two (2) years
          after the date upon which a Change of Control occurs, of any one or
          more of the following:

          (i)   a reduction in Employee's annual salary from the level in effect
                immediately prior to the Change of Control;

          (ii)  failure of Canaan or any of its successors or assigns to provide
                Employee with an annual bonus, incentive compensation or other
                employee benefits (including but not limited to medical, dental,
                life insurance, accidental, death and long-term disability
                plans) that are materially consistent with such annual bonuses,
                incentive compensation or other employee benefits provided by
                Canaan or any of its successors or assigns to employees with
                comparable duties;

          (iii) a significant adverse alteration in the nature or status of
                Employee's duties, title, responsibilities, or the conditions of
                Employee's employment from those in effect immediately prior to
                such Change in Control; or

          (iv)  a change in the location of Employee's principal place of
                employment by Canaan or any of its successors or assigns by more
                than fifty (50) miles from the location where Employee was
                principally employed immediately preceding to the date on which
                a Change of Control occurs.

     (b)  "Change of Control" shall mean the occurrence after the effective date
          of this Agreement of:

          (i)   an acquisition (other than directly from Canaan) of any voting
                securities of Canaan (the "Voting Securities") by any "Person"
                (as the term person is used for purposes of Section 13(d) or
                14(d) of the Securities Exchange Act of 1934, as amended (the
                "Exchange Act")) immediately after which such

<PAGE>

                Person has "Beneficial Ownership" (within the meaning of Rule
                13d-3 promulgated under the Exchange Act) of fifty percent (50%)
                or more of the combined voting power of Canaan's then
                outstanding Voting Securities;

          (ii)  the individuals who, as of the effective date of this Agreement,
                are members of the Board of Directors of Canaan (the "Incumbent
                Board"), cease for any reason to constitute at least two-thirds
                of the members of the Board of Directors of Canaan (the
                "Board"); provided, however, that if the election, or nomination
                for election by Canaan's common stockholders, of any new
                director was approved by a vote of at least two-thirds of the
                Incumbent Board, such new director shall, for purposes of this
                Agreement, be considered as a member of the Incumbent Board;
                provided further, however, that no individual shall be
                considered a member of the Incumbent Board if such individual
                initially assumed office as a result of either an actual or
                threatened "election contest" (as described in Rule 14A-11
                promulgated under the Exchange Act) or other actual or
                threatened solicitation of proxies or consents by or on behalf
                of a Person other than the Board (a "Proxy Contest") including
                by reason of any agreement intended to avoid or settle any
                Election Contest or Proxy Contest; or

          (iii) consummation of:

                (A) A merger, consolidation or reorganization involving Canaan,
                    unless:

                    (1)  the stockholders of Canaan, immediately before such
                         merger, consolidation or reorganization, own directly
                         or indirectly immediately following such merger,
                         consolidation or reorganization, at least sixty percent
                         (60%) of the combined voting power of the outstanding
                         voting securities of the corporation resulting from
                         such merger or consolidation or reorganization (the
                         "Surviving Corporation") in substantially the same
                         proportion as their ownership of the Voting Securities
                         immediately before such merger, consolidation or
                         reorganization;

                    (2)  the individuals who were members of the Incumbent Board
                         immediately prior to the execution of the agreement
                         providing for such merger, consolidation or
                         reorganization constitute at least two-thirds of the
                         members of the board of directors of the Surviving
                         Corporation; and

                    (3)  no person other than Canaan, any subsidiary, any
                         employee benefit plan (or any trust forming a part
                         thereof) maintained by Canaan, the Surviving
                         Corporation, or any subsidiary, or

                                       2

<PAGE>

                         any person who, immediately prior to such merger,
                         consolidation or reorganization had Beneficial
                         Ownership of fifty percent (50%) or more of the then
                         outstanding Voting Securities, has Beneficial Ownership
                         of fifty percent (50%) or more of the combined voting
                         power of the Surviving Corporation's then outstanding
                         voting securities.

               (B)  a complete liquidation or dissolution of Canaan; or

               (C)  an agreement for the sale or other disposition of all or
                    substantially all of the assets of Canaan to any Person
                    (other than a transfer to a subsidiary).

     Notwithstanding the foregoing, a Change of Control shall not be deemed to
     occur solely because any Person (the "Subject Person") acquired Beneficial
     Ownership of more than the permitted percent of the outstanding Voting
     Securities as a result of the acquisition of Voting Securities by Canaan
     that, by reducing the number of Voting Securities outstanding, increases
     the proportional number of shares Beneficially Owned by the Subject Person,
     provided that if a Change of Control would occur (but for the operation of
     this sentence) as a result of the acquisition of Voting Securities by
     Canaan, and after such share acquisition by Canaan, the Subject Person
     becomes the Beneficial Owner of any additional Voting Securities that
     increases the percentage of the then outstanding Voting Securities
     Beneficially Owned by the Subject Person, then a Change of Control shall
     occur.

     (c)  "Code" shall mean the Internal Revenue Code of 1986, as amended.

     (d)  "Compensation" shall mean the sum of:

          (i)  Employee's annual salary at the rate in effect immediately prior
               to the date on which a Change of Control occurs; and

          (ii) the highest annual bonus received by Employee during the three
               (3) years immediately prior to the date on which a Change of
               Control occurs.

     (e)  "Involuntary Termination" shall mean any termination of Employee's
          employment with Canaan or any of its successors or assigns other than
          (i) termination for cause; (ii) termination as a result of death or
          disability; (iii) retirement; or (iv) resignation by Employee except
          resignation on or before the date that is ninety (90) days after the
          date upon which Employee receives notice of a Change in Duties.

     (f)  "Retirement" shall mean Employee's resignation on or after the date
          Employee reaches age sixty-five (65).

                                       3

<PAGE>

     (g)  "Severance Amount" shall mean an amount equal to three (3) times
          Employee's Compensation.

     (h)  "Termination for Cause" shall mean an Employee's termination of
          employment with Canaan or any of its successors or assigns because of:

          (i)  Employee's failure to devote reasonable time and effort to the
               performance of Employee's duties, and such failure has not been
               cured within thirty (30) days of the receipt by Employee of
               written notice thereof, which written notice shall specifically
               identify how Employee has not devoted reasonable time and effort
               to the performance of duties; or

          (ii) Employee's willful engagement in misconduct that is materially
               injurious to Canaan, monetarily and otherwise, and such
               midconduct has not been cured within thirty (30) days of the
               receipt by written notice thereof.

2.   SEVERANCE BENEFITS. If Employee's employment by Canaan or any of its
     ------------------
     successors or assigns is subject to an Involuntary Termination that occurs
     within two (2) years after the date upon which a Change of Control occurs,
     then Employee shall be entitled to receive, as additional compensation for
     services rendered to Canaan or any of its successors or assigns, at
     Employee's option, a lump sum cash payment, which payment shall be paid
     within ten (10) business days after ther effective date of the Involuntary
     Termination, in an amount equal to:

     (a)  if such payment is subject to Code Section 280G, the maximum amount
          payable to Employee without such payment (or any portion thereof)
          being characterized as a "parachute payment" pursuant to Code Section
          280G(b)(2)(A) after taking into consideration all payments to Employee
          covered by such section, which shall be limited to those payments
          calculated in the manner required under Code Section 280G that
          Employee receives or is deemed to receive (i) under this Agreement;
          (ii) under the Canaan Stock Option Plan by reason of the acceleration
          of any vesting of options granted thereunder; or (iii) under any other
          plan or arrangement that would otherwise be considered a "parachute
          payment" under Code Section 280G. Such payment shall be accompanied by
          a notice specifying the calculation of the payment as well as the
          amount of any "parachute payments" and the Company's deduction limit
          under Code Section 280G. Such notice shall contain sufficient detail
          to enable the Employee to challenge Canaan's computation of any
          payment without significant additional information; or

     (b)  if such payment is not subject to Code Section 280G, the greater of
          (i) the amount calculated under paragraph 2(a) hereof, as if such
          payment were subject to Code Section 280G, or (ii) the Severance
          Amount. Such payment shall be accompanied by a notice specifying the
          calculation of the payment, which note shall contain sufficient detail
          to enable Employee

                                       4

<PAGE>

               to challenge Canaan's computation of any payment without
               significant additional information.

     If Employee objects to Canaan's computation of any payment, he shall
     deliver to Canaan (or its respective successors or assigns) a dispute
     notice (signed by Employee) within fifteen (15) business days of receipt by
     Employee of the payment. If a dispute notice is not delivered prior to the
     expiration of such period, Canaan's calculation shall be final and binding
     on each party hereto. If a dispute notice is delivered to Canaan (or its
     respective successors or assigns), Canaan (or its respective successors or
     assigns) and Employee shall negotiate in good faith to resolve any
     differences related to the calculation of the payment promptly following
     delivery of the dispute notice. If Canaan (or its respective successors or
     assigns) and Employee fail to reach an agreement after ten (10) business
     days of such good faith negotiations, then the payment shall be determined
     by the Oklahoma City, Oklahoma office of a major national accounting firm
     agreed upon by Canaan (or its respective successors or assigns) and
     Employee (or, if they do not so agree within ten (10) business days, then
     each of them shall select such an accounting firm and the two firms so
     selected shall select a third such firm within ten (10) business days) (the
     "Determining Party"), whose determination of the payment shall be final and
     binding on each party hereto. Canaan (or its respective successors or
     assigns) and Employee will fully cooperate with the Determining Party in
     order to enable the Determining Party to reach its determination of the
     payment as soon as practicable, but in no event later than thirty (30) days
     after the matter is referred to the Determining Party. The cost of
     retaining the Determining Party with respect to a dispute regarding the
     payment will be borne by Canaan (or its respective successors or assigns).

3.   TERM. The term of this Agreement shall commence on the effective date
     ----
hereof and shall terminate on January 31, 2007 (the "Initial Term"). Unless
terminated as provided below, this Agreement shall be renewed automatically for
consecutive five-year periods as of January 31 of each successive fifth year
commencing January 31, 2007 (each such five-year period, a "Renewal Term") (the
Initial Term and all Renewal Terms are hereinafter collectively referred to as
the "Term"). On or before ninety (90) days immediately preceding the termination
of the Initial Term or any Renewal Term, Canaan shall have the right to review
this Agreement, and either continue and extend this Agreement, terminate this
Agreement, which termination shall be effective as of the termination of then
Initial Term or any Renewal Term, as the case may be, and/or offer Employee a
different agreement. Canaan will notify Employee of such action on or before
such ninety (90) day period. This Agreement shall remain in effect until
terminated as provided above and/or modified by Canaan. Failure of Canaan to
take any action on or before such ninety (90) day period shall be considered as
an extension of this Agreement for an additional five-year (5) period of time.
If a Change of Control occurs while this Agreement is in effect, then this
Agreement shall not be subject to termination or modification and shall remain
in force for a period of two (2) years after such Change of Control, and if
within said two (2) years the contingency factors occur that would entitle
Employee to the benefits as provided herein, this Agreement shall remain in
effect in accordance with its terms.

          effect and shall not be affected by the illegal, invalid, or

          Agreement corresponding to the unenforceable provision); and in lieu
          of such illegal, invalid, or unenforceable provision, there shall be
          added automatically as part of this Agreement, a provision as similar
