                                      -3-
<PAGE>   5

                  registration on any appropriate form under the Act, which form
                  shall be available for the sale of the Transfer Restricted
                  Securities in accordance with the intended method or methods
                  of distribution thereof within the time periods and otherwise

                  Statement any securities other than the Transfer Restricted

                  Restricted Securities during the period required by this
                  Agreement, the Company shall file promptly (A) an appropriate
                  amendment to such Shelf Registration Statement curing such
                  defect, and, if Commission review is required, use its best
                  efforts to cause such amendment to be declared effective as
                  soon as practicable, (B) a supplement pursuant to Rule 424
                  under the Act curing such defect or (C) an Exchange Act report
                  incorporated by reference curing such defect;

                           (iii) prepare and file with the Commission such
                  amendments and post-effective amendments to the Shelf
                  Registration Statement as may be necessary to keep such Shelf
                  Registration Statement effective for the applicable period set
                  forth in Section 3 hereof, cause the Prospectus to be
                  supplemented by any required Prospectus supplement, and as so
                  supplemented to be filed pursuant to Rule 424 under the Act,
                  and to comply fully with Rules 424, 430A and 462, as
                  applicable, under the Act in a timely manner; and comply with
                  the provisions of the Act with respect to the disposition of
                  all Transfer Restricted Securities covered by such Shelf
                  Registration Statement during the applicable period in
                  accordance with the intended method or methods of distribution
                  by the sellers thereof set forth in such Shelf Registration
                  Statement or supplement to the Prospectus;

                           (iv) advise the Holders and underwriters, if any,
                  promptly and, if requested by such Persons, confirm such
                  advice in writing, (A) when the Shelf Registration Statement
                  or any Prospectus supplement or post- effective amendment has
                  been filed, and, with respect to the Shelf Registration
                  Statement or any post-effective amendment thereto, when the

                  Commission for amendments to the Shelf Registration Statement
                  or amendments or supplements to the Prospectus or for
                  additional information relating thereto, (C) of the issuance
                  by the Commission of any stop order suspending the
                  effectiveness of the Shelf Registration Statement under the

                  the qualification of the Transfer Restricted Securities for
                  offering or sale in any jurisdiction, or the initiation of any
                  proceeding for any of the preceding purposes, (D) of the
                  existence of any fact or the happening of any event that makes
                  any statement of a material fact made in the Shelf
                  Registration Statement, the Prospectus, any amendment or
                  supplement thereto made, not misleading;

                           (v) subject to Section 5(a)(ii), if any fact or event
                  contemplated by Section 5(iv)(D) above shall exist or have
                  occurred, prepare a post-effective amendment or supplement to
                  the Shelf Registration Statement or related Prospectus or any
                  document incorporated therein by reference or file any other
                  required document so that, as thereafter delivered to the
                  purchasers of Transfer Restricted Securities, the Prospectus
                  will not contain an untrue statement of a material fact or
                  omit to state any material fact necessary to make the
                  statements therein, in the light of the circumstances under
                  which they were made, not misleading;

                           (vi) deliver to each Holder and underwriter, if any,
                  without charge, a reasonable number of copies of the

                  amendment or supplement thereto as such Holder or underwriter
                  reasonably may request; the Company hereby consents to the use
                  (in accordance with law) of the Prospectus and any amendment
                  or supplement thereto by each Holder and each underwriter, if

Section 5(a)(iv)(C), (ii) any notice from the Company of the existence of any
fact of the kind described in Section 5(a)(iv)(D) hereof or (iii) any notice
from the Company that (a) sales under the Shelf Registration Statement would
require the disclosure of material information which the Company has a bona fide
business purpose for preserving as confidential, or (b) such disclosure would
impede the Company's ability to consummate a material transaction (in each case,
a "SUSPENSION NOTICE"), such Holder will forthwith discontinue disposition of
Transfer Restricted Securities pursuant to the Shelf Registration Statement
until (A) such Holder has received copies of the supplemented or amended
Prospectus contemplated by Section 5(a)(v) hereof, or (B) such Holder is advised
in writing by the Company that the use of the Prospectus may be resumed, and has
received copies of any additional or supplemental filings that are incorporated
by reference in the Prospectus (in each case, the "RECOMMENCEMENT DATE"),
provided, that any suspension pursuant to clause (iii) above shall not exceed 60
days in any twelve-month period. Each Holder receiving a Suspension Notice
hereby agrees that it will either (x) destroy any Prospectuses, other than
permanent file copies, then in such Holder's possession which have been replaced
by the Company with more recently dated Prospectuses or (y) deliver to the
Company (at the Company's expense) all copies, other than permanent file copies,
then in such Holder's possession of the Prospectus covering such Transfer
Restricted Securities that was current at the time of receipt of the Suspension
Notice.

                           (c) Restrictions on the Company. During the period
                  specified in Section 3 of this Agreement, the Company will not
                  effect any public sale or distribution of any securities the
                  same as or similar to the Transfer Restricted Securities, or
                  any securities convertible into or exchangeable or exercisable
                  for any Company securities the same as or similar to the
                  Transfer Restricted Securities (except pursuant to
                  registration on Form S-4 or any successor form, or otherwise
                  in connection with the acquisition of a business or assets of
                  a business, a merger, or an exchange offer for the securities
                  of the issuer of another entity, or registrations on Form S-8
                  or any successor form relating solely to securities offered
                  pursuant to any benefit plan), during the 14-day period prior
                  to and through the period (i) beginning on the commencement of
                  the public distribution of Transfer Restricted Securities
                  pursuant to the Shelf Registration Statement in an
                  underwritten offering by or on behalf of any Holder to the
                  extent timely notified in writing by the selling Holders or
                  the underwriters managing such distribution and (ii) ending on
                  the first to occur of (A) the 90th day after such commencement
                  and (B) the end of such distribution (the "Company Standstill
                  Period"), including that portion of such period following an
                  underwritten distribution commenced during the Company
                  Standstill Period that does not coincide with the Company
                  Standstill Period.

SECTION 6. PIGGYBACK REGISTRATIONS

         (a) In addition to the agreements relating to the Shelf Registration
Statement the Company agrees as follows:

                           (i) If at any time the Company proposes to file an
                  additional registration statement under the Act with respect
                  to an offering of Common Stock (x) for the Company's own
                  account (except pursuant to registrations on Form S-4 or any
                  successor form, or Form S-8 or any successor form relating
                  solely to securities issued pursuant to any benefit plan) or
                  (y) for the account of any holders of Common Stock other than
                  the Noteholders, then (A) the Company shall give written
                  notice of such proposed filing to the Noteholders as soon as
                  practicable (but in no event less than 30 days before the
                  anticipated filing date), (B) such notice shall offer each
                  Noteholder, subject to the terms and conditions hereof, the
                  opportunity to request that such actions be taken under Rule
                  429 under the Act ("Rule 429") as shall cause the prospectus
                  contained in such additional registration statement (a
                  "Noteholder Piggyback Registration Statement") to be available
                  to permit the offer and sale, at such Noteholder's election,
                  of some or all of the Transfer Restricted Securities owned by
                  such Noteholder on the same terms and conditions as the
                  Company's or such other holder's Common Stock (a Noteholder
                  Piggyback Sale"), and (C) the Company shall otherwise take
                  such reasonable actions as will enable such Noteholder to
                  effect a Noteholder Piggyback Sale on such terms and
                  conditions.

                           (ii) Subject to Section 6(b), the Company shall take
                  such actions as shall be required under Rule 429 to cause the
                  combined prospectus contained in such Noteholder Piggyback
                  Registration Statement to permit the offer and sale of all
                  Transfer Restricted Securities requested by such Noteholder
                  within 20 days after the receipt of any notice given by the
                  Company pursuant to Section 6(a)(i), clause (A), to be covered
                  by such combined prospectus; provided, however, that if, at
                  any time after giving written notice of its intention to
                  register any securities and prior to the effective date of
                  such Noteholder Piggyback Registration Statement, the Company
                  shall determine for any reason not to register or to delay
                  registration of such securities, the Company may, at its
                  election, give written notice of such determination to each
                  Noteholder and, thereupon, (i) in the case of a determination
                  not to register, will be relieved of any obligation to cause
                  any Transfer Restricted Securities to be covered by such
                  combined prospectus, without prejudice, however, to the rights
                  of any Noteholder to have its Transfer Restricted Securities
                  continue to be included in the Shelf Registration Statement
                  and (ii) in the case of a determination to delay registering,
                  shall be permitted to delay causing any Transfer Restricted
                  Securities to be covered by the combined prospectus for the
                  same period as the delay in registering such other securities.

                           (iii) If the offering pursuant to such Noteholder
                  Piggyback Registration Statement is to be underwritten, then
                  each Noteholder making a request for a Noteholder Piggyback
                  Sale pursuant to this Section 6(a) must participate in such
                  underwritten offering and shall not be permitted to make any
                  other offering in connection with such registration. If the
                  offering pursuant to such Noteholder

                                      -8-
<PAGE>   10

                  Piggyback Registration Statement is to be on any other terms,
                  then each Noteholder making a request for a Noteholder
                  Piggyback Sale pursuant to this Section 6(a) must participate
                  in such offering on such basis and shall not be permitted to
                  make an underwritten offering in connection with such
                  registration. Each Noteholder shall be permitted to withdraw
                  all or part of such Noteholder's Transfer Restricted
                  Securities from coverage by a Noteholder Piggyback
                  Registration Statement at any time prior to (but only prior
                  to) the effective date thereof without prejudice to the rights
                  of such Noteholder to have its Transfer Restricted Securities
                  continue to be included in the Shelf Registration Statement.

         (b) Notwithstanding anything contained herein, if the managing
underwriter or underwriters of a sale or offering described in Section 6(a)
pursuant to which a Noteholder has requested a Noteholder Piggyback Sale shall
advise the Company in writing that (x) the size of the offering that the
Noteholders, the Company and any other holders intend to make or (y) the kind of
securities that one or more Noteholders, the Company and such other holders
intend to include in such offering are such that the success of the offering
would be materially and adversely affected, then (A) if the size of the offering
is the basis of such underwriter's advice, the amount of Transfer Restricted
Securities to be offered for the account of any Noteholder shall be reduced to
the extent necessary to reduce the total amount of securities to be included in
such offering to the amount recommended by such managing underwriter or
underwriters; provided, however, that, if securities are being offered for the
account of Persons other than the Company or such Noteholder, the proportion by
which the amount of such Transfer Restricted Securities intended to be offered
for the account of any Noteholder is reduced shall not exceed the proportion by
which the amount of such securities intended to be offered for the account of
such Persons is reduced; and (B) if the combination of securities to be offered
is the basis of such underwriter's advice (1) the Transfer Restricted Securities
to be included in such offering shall be reduced as described in clause (A)
above (subject to the provision in clause (A)) or (2) if the actions described
in sub-clause (1) of this clause (B) would, in the judgment of the managing
underwriter, be insufficient to eliminate the adverse effect that inclusion of
the Transfer Restricted Securities requested to be included would have on such
offering, such Transfer Restricted Securities will be excluded from such
offering, but only if all shares of Common Stock are also excluded. Any
reduction in Transfer Restricted Securities to be included in an underwritten
offering as contemplated by this Section 6(b) shall be without prejudice to the
Noteholders' rights to have their Transfer Restricted Securities continue to be
included in the Shelf Registration Agreement.

SECTION 7. REGISTRATION EXPENSES

(a) All expenses incident to the Company's performance of or compliance with
this Agreement will be borne by the Company, regardless of whether a Shelf
Registration Statement required by this Agreement becomes effective, including
without limitation: (i) all registration and filing fees and expenses; (ii) all
fees and expenses of compliance with federal securities and state Blue Sky or
securities laws; (iii) all expenses of printing, messenger and delivery services
and telephone; (iv) all fees and disbursements of counsel for the Company and
not more than one counsel for the Holders of Transfer Restricted Securities as
described in Section 7(b) below; (v) all application and filing fees in
connection with listing the Common Stock on a national securities exchange
pursuant to the requirements hereof; (vi) all fees and disbursements of
independent certified public accountants of the

                                      -9-
<PAGE>   11

Company (including the expenses of any special audit and comfort letters
required by or incident to such performance); ; and (vii) fees and expenses in
connection with any review of underwriting arrangements by the National
Association of Securities Dealers, Inc. including fees and expenses of any
"qualified independent underwriter" in connection with an underwritten offering.

         The Company will, in any event, bear its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expenses of any annual audit and the
fees and expenses of any Person, including special experts, retained by the
Company. The Noteholders will bear the expense of any underwriting commissions
in connection with an underwritten offering.

         (b) The Company will reimburse the Holders selling Transfer Restricted
Securities pursuant to the "Plan of Distribution" contained in the Shelf
Registration Statement for the reasonable fees and disbursements of not more
than one counsel selected by the Holders of a majority of the Transfer
Restricted Securities.

SECTION 8. INDEMNIFICATION

         (a) The Company agrees to indemnify and hold harmless each Holder, its
directors, its officers and each Person, if any, who controls such Holder
(within the meaning of Section 15 of the Act and Section 20 of the Exchange
Act), from and against any and all losses, claims, damages, liabilities,
judgments, (including without limitation, any legal or other expenses incurred
in connection with investigating or defending any matter, including any action
that could give rise to any such losses, claims, damages, liabilities or
judgments) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Shelf Registration Statement, preliminary
prospectus or Prospectus (or any amendment or supplement thereto) provided by
the Company to any Holder or any prospective purchaser of Shares pursuant to the
Shelf Registration Statement or caused by any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, except insofar as such losses, claims,
damages, liabilities or judgments are caused by an untrue statement or omission
or alleged untrue statement or omission that is based upon information relating
to any of the Holders furnished in writing to the Company by any of the Holders
expressly for use in the Shelf Registration Statement or Noteholder Piggyback
Registration Statement.

         (b) Each Holder of Transfer Restricted Securities agrees, severally and
not jointly, to indemnify and hold harmless the Company and its directors and
officers, and each Person, if any, who controls (within the meaning of Section
15 of the Act or Section 20 of the Exchange Act) the Company, to the same extent
as the foregoing indemnity from the Company set forth in section (a) above, but
only with reference to information relating to such Holder furnished in writing
to the Company by such Holder expressly for use in the Shelf Registration
Statement.

         (c) In case any action shall be commenced involving any Person in
respect of which indemnity may be sought pursuant to Section 7(a) or 7(b) (the
"indemnified party"), the indemnified party shall promptly notify the Person
against whom such indemnity may be sought (the "indemnifying party") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees

                                      -10-
<PAGE>   12

and expenses of such counsel, as incurred (except that in the case of any action
in respect of which indemnity may be sought pursuant to both Sections 7(a) and
7(b), a Holder shall not be required to assume the defense of such action
pursuant to this Section 7(c), but may employ separate counsel and participate
in the defense thereof, but the fees and expenses of such counsel, except as
provided below, shall be at the expense of the Holder). Any indemnified party
shall have the right to employ separate counsel in any such action and
participate in the defense thereof, but the fees and expenses of such counsel
shall be at the expense of the indemnified party unless (i) the employment of
such counsel shall have been specifically authorized in writing by the
indemnifying party, (ii) the indemnifying party shall have failed to assume the
defense of such action or employ counsel reasonably satisfactory to the
indemnified party or (iii) the named parties to any such action (including any
impleaded parties) include both the indemnified party and the indemnifying
party, and the indemnified party shall have been advised by such counsel that
there may be one or more legal defenses available to it which are different from
or additional to those available to the indemnifying party (in which case the
indemnifying party shall not have the right to assume the defense of such action
on behalf of the indemnified party). In any such case, the indemnifying party
shall not, in connection with any one action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the fees and expenses of
more than one separate firm of attorneys (in addition to any local counsel) for
all indemnified parties and all such fees and expenses shall be reimbursed as
they are incurred. Such firm shall be designated in writing by the Holders of a
majority of the Transfer Restricted Securities, in the case of the parties
indemnified pursuant to Section 7(a), and by the Company, in the case of parties
indemnified pursuant to Section 7(b). The indemnifying party shall indemnify and
hold harmless the indemnified party from and against any and all losses, claims,
damages, liabilities and judgments by reason of any settlement of any action (i)
effected with its written consent or (ii) effected without its written consent
if the settlement is entered into more than (20) twenty Business Days after the
indemnifying party shall have received a request from the indemnified party for
reimbursement for the fees and expenses of counsel (in any case where such fees
and expenses are at the expense of the indemnifying party) and, prior to the
date of such settlement, the indemnifying party shall have failed to comply with
such reimbursement request. No indemnifying party shall, without the prior
written consent of the indemnified party, effect any settlement or compromise
of, or consent to the entry of judgment with respect to, any pending or
threatened action in respect of which the indemnified party is or could have
been a party and indemnity or contribution may be or could have been sought
hereunder by the indemnified party, unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability on claims that are or could have been the subject matter of such
action and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of the indemnified party.

         (d) To the extent that the indemnification provided for in this Section
7 is unavailable to an indemnified party in respect of any losses, claims,
damages, liabilities or judgments referred to therein, then each indemnifying
party, in lieu of indemnifying such indemnified party, shall contribute to the
amount paid or payable by such indemnified party as a result of such losses,
claims, damages, liabilities or judgments in such proportion as is appropriate
to reflect the relative fault of the Company on the one hand, and of the
Holders, on the other hand, in connection with the statements or omissions which
resulted in such losses, claims, damages, liabilities or judgments, as well as
any other relevant equitable considerations. The relative fault of the Company,
on the one hand, and of the Holders, on the other hand, shall be determined by
reference to, among other things, whether the

                                      -11-
<PAGE>   13

untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the
Company, on the one hand, or by the Holders, on the other hand, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The amount paid or payable by a party as a
result of the losses, claims, damages, liabilities and judgments referred to
above shall be deemed to include any legal or other fees or expenses reasonably
incurred by such party in connection with investigating or defending any action
or claim.

         The Company and each Holder agree that it would not be just and
equitable if contribution pursuant to this Section 8(d) were determined by pro
rata allocation (even if the Holders were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities or judgments referred to in the immediately
preceding paragraph shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any matter, including any action that could have given rise to such
losses, claims, damages, liabilities or judgments. Notwithstanding the
provisions of this Section 8, no Holder will be required to contribute any
amount in excess of the amount by which the net proceeds of the offering (before
deducting expenses) received by such Holder exceeds the amount of damages that
such Holder has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Holders' obligations to contribute pursuant to
this Section 8(d) are several in proportion to the respective Transfer
Restricted Securities held by each of the Holders hereunder and not joint.

SECTION 9. RULE 144A AND RULE 144

         The Company agrees with each Holder, for so long as any Transfer
Restricted Securities remain outstanding and during any period in which the
Company (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make
available, upon request of any Holder of Transfer Restricted Securities, to any
Holder or beneficial owner of Transfer Restricted Securities in connection with
any sale thereof and any prospective purchaser of Transfer Restricted Securities
designated by such Holder or beneficial owner, the information required by Rule
144A(d)(4) under the Act in order to permit resale of such Transfer Restricted
Securities pursuant to Rule 144A, and (ii) is subject to Section 13 or 15(d) of
the Exchange Act, to make all filings required thereby in a timely manner in
order to permit resales of such Transfer Restricted Securities pursuant to Rule
144 (if available).

SECTION 10. REPRESENTATIONS

                           (a) The Company (i) is a corporation duly organized,
                  validly existing and in good standing under the laws of the
                  State of Oklahoma, (ii) has the corporate power to execute and
                  deliver this Agreement and to consummate the transactions
                  contemplated hereby and (iii) is not in default under or in
                  violation of any provision of the Company's certificate of
                  incorporation or bylaws.

                                      -12-
<PAGE>   14

                  (b) The authorized capital stock of the Company consists of
                  250,000,000 shares of Common Stock and 10,000,000 shares of
                  preferred stock of which 122,721,082 shares of Common Stock
                  and 2,492,037 shares of preferred stock were issued and
                  outstanding as of June 16, 2000.

                           (c) The Company has delivered or made available to
                  the Noteholder each registration statement, report, definitive
                  proxy statement or definitive information statement and all
                  exhibits thereto filed since December 31, 1998, each in the
                  form (including exhibits and any amendments thereto) filed
                  with the Commission. Except as otherwise disclosed, such
                  reports were filed with the Commission in a timely manner,
                  constitute all forms, reports and documents required to be
                  filed by the Company under the Act, the Exchange Act and the
                  rules and regulations promulgated thereunder. As of their
                  respective dates, such reports (a) complied as to form in all
                  material respects with the applicable requirements of the Act
                  and the Exchange Act and (b) did not contain any untrue
                  statement of a material fact or omit to state a material fact
                  required to be stated therein or necessary to make the
                  statements made therein not misleading. Each of the balance
                  sheets of the Company included in or incorporated by reference
                  in such reports (including the related notes and schedules)
                  fairly presents the financial position of the Company as of
                  the date thereof and each of the statements of income,
                  retained earnings and cash flow of the Company included or
                  incorporated by reference into such reports (including any
                  related notes and schedules) fairly presents the results of
                  operations, retained earnings or cash flows, as the case may
                  be, of the Company for the periods set forth therein (subject,
                  in the case of unaudited statements, to normal year-end audit
                  adjustments which would not be material in amount or effect),
                  in each case in accordance with generally accepted accounting
                  principles consistently applied during the periods involved,

                  Agreement nor compliance with the terms and provisions of this
                  Agreement will violate any law, statute, rule or regulation of

                  or instrument to which the Company is a party.

SECTION 11. MISCELLANEOUS

         (a) Remedies. The Company acknowledges and agrees that any failure by
the Company to comply with its obligations under Section 3 hereof may result in
material irreparable injury to the Noteholders or the Holders for which there is
no adequate remedy at law, that it will not be possible to measure damages for
such injuries precisely and that, in the event of any such failure, the
Noteholders or any Holder may obtain such relief as may be required to
specifically enforce the Company's obligations under Section 3 hereof. The
Company further agrees to waive the defense in any action for specific
performance that a remedy at law would be adequate.

         (b) No Inconsistent Agreements. The Company will not, on or after the
date of this Agreement, enter into any agreement with respect to its securities
that is inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. The Company has not previously
entered into any agreement (which has not expired or been terminated) granting
any registration rights with respect to its securities to any Person. The rights
granted to the Holders hereunder do not in any way conflict with and are not
inconsistent with the rights granted to the holders of the Company's securities
under any agreement in effect on the date hereof.

         (c) No Piggybacks on Shelf Registration Statement. The Company shall
not grant to any of its security holders (other than the holders of Transfer
Restricted Securities in such capacity) the right to include any of their
securities in the Shelf Registration Statement other than the Transfer
Restricted Securities.

         (d) Amendments and Waivers. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to or departures from
the provisions hereof may not be given unless (i) in the case of Section 3
hereof and this Section 10(d)(i), the Company has obtained the written consent
of Holders of all outstanding Transfer Restricted Securities and (ii) in the
case of all other provisions hereof, the Company has obtained the written
consent of Holders of Shares representing a majority of the outstanding Transfer
Restricted Securities (excluding Transfer Restricted Securities held by the
Company or its Affiliates).

         (e) Third Party Beneficiary. The Holders shall be third party
beneficiaries to the agreements made hereunder between the Company, on the one
hand, and the Noteholders, on the other hand, and shall have the right to
enforce such agreements directly to the extent they may deem such enforcement
necessary or advisable to protect their rights hereunder.

of and be binding upon the successors and assigns of each of the parties,
including without limitation and without the need for an express assignment,
subsequent Holders of Transfer Restricted Securities; provided, that nothing
herein shall be deemed to permit any assignment, transfer or other disposition
of Transfer Restricted Securities in violation of the terms hereof or of the
Purchase Agreements. If any transferee of any Holder shall acquire Transfer
Restricted Securities in any manner, whether by operation of law or otherwise,
such Transfer Restricted Securities shall be held subject to all of the terms of
this Agreement, and by taking and holding such Transfer Restricted Securities
such Person shall be conclusively deemed to have agreed to be bound by and to
perform all of the terms and provisions of this Agreement, including the
restrictions on resale set forth in this Agreement and the applicable Purchase
Agreement, and such Person shall be entitled to receive the benefits hereof.

         (h) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO THE
CONFLICT OF LAW RULES THEREOF.

         (k) Severability. In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby.

         (l) Entire Agreement. This Agreement, together with the Purchase
Agreements, is intended by the parties as a final expression of their agreement
and intended to be a complete and exclusive statement of the agreement and
understanding of the parties hereto in respect of the subject matter contained
herein. There are no restrictions, promises, warranties or undertakings, other
than those set forth or referred to herein with respect to the registration
rights granted with respect to the Transfer Restricted Securities. This
Agreement supersedes all prior agreements and understandings between the parties
with respect to such subject matter.

         (m) Common Stock Issuance. Under the terms of paragraph 10.1 of each of
the Purchase Agreements, CEMI is obligated to cause the issuance of additional
shares of Common Stock or to pay additional cash to the Noteholders under
certain circumstances. The Company agrees to reserve sufficient shares to
satisfy any such obligations, to list such shares of Common Stock with the New
York Stock Exchange as provided herein and to include such shares in the Shelf
Registration Statement. If CEMI does not satisfy the obligations under paragraph
10.1 of any Purchase Agreement by issuing the required shares of Common Stock or
paying the required amount of cash, the Company will issue the number of shares
of Common Stock directly to the appropriate Noteholder required to satisfy such
obligations under the appropriate Purchase Agreement.

         IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first written above.

                              EMPLOYMENT AGREEMENT

         THIS AGREEMENT is made effective June 1, 2000 between CHESAPEAKE ENERGY
CORPORATION, an Oklahoma corporation (the "Company"), and MARCUS C. ROWLAND, an
individual (the "Executive") and replaces and supersedes those certain
Employment Agreements between Company and Executive dated March 1, 1995, July 1,
1997, and July 1, 1998.

                                   WITNESSETH:

         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 part-time basis. The
Executive will commit to a schedule to be mutually determined by Executive and
the Company from time to time, to average a minimum of two work days per week.
Initially the schedule will include all day Monday, one-half day Tuesday and
one-half day Wednesday. 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, subject to the part-time provision of the Employment
         Agreement. 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.

                                       1
<PAGE>   5

         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 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. The Executive currently conducts oil and gas activities
individually and through various related or family-owned entities, including
Infinity Resources, L.L.C. The Executive will be permitted to continue oil and
gas activities individually, and directly or indirectly through Infinity
Resources, L.L.C., provided that the Executive, subsequent to June 1, 2000, will
not 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. In the event the Executive or the Company becomes
aware of any oil and gas activities by the Executive that may violate the
foregoing provision, the party discovering the activity will immediately notify
the other party in writing and Executive will use his good faith efforts to
correct the situation by sale or transfer to the Company.

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 One Hundred Ten Thousand Dollars ($110,000.00),
         will be paid to the Executive in equal semi-monthly installments
         beginning June 15, 2000 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:

         4.4.1   Vacation. The Executive will be entitled to take three (3)
                 part-time weeks of paid vacation during each twelve month
                 period 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) forty percent (40%) of the monthly dues necessary to
                 maintain a full membership in a country club in the Oklahoma
                 City area selected by the Executive; and (b) one hundred
                 percent (100%) of the reasonable cost of any qualified Company
                 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.

                                       3

         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   Aircraft Allowance. The Executive will receive the right to use
                 up to ten (10) hours of flight time on the Company's aircraft
                 during each twelve (12) month period covered by this Agreement.
                 Executive agrees to reimburse company for the variable costs
                 associated with this use of flight time.

5. Term. In the absence of termination as set forth in paragraph 6 below, this
Agreement will extend for a term of two (2) years and one (1) month commencing
on June 1, 2000, and ending on June 30, 2002 (the "Expiration Date").

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

   6.1   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 thirty (30) 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 for a
                 three (3) month period following notice of termination; (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

                                       4
<PAGE>   8

                 business of the Company which results in injury to the Company;
                 (d) willfully and repeatedly fails to perform the Executive's
                 duties hereunder, or e) violates the Noncompetition paragraph
                 of this Agreement. 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. 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.

   6.2   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 thirty (30) 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.

   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 six (6) 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

                                       5
<PAGE>   9

         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 ("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.

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

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. 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 9 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.

    10.1    Time. Time is of the essence of each provision of this Agreement.
