                  (i) use its best efforts to effect such registration to permit
             the sale of the Transfer Restricted Securities being sold in
             accordance with the intended method or methods of distribution
             thereof (as indicated in the information furnished to the Company
             pursuant to Section 4 hereof), and pursuant thereto the Company
             will prepare and file with the Commission a Shelf Registration
             Statement relating to the 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 in accordance with the provisions hereof. The Company

             such Shelf Registration Statement or the Prospectus contained
             therein (i) to contain an untrue statement of a material fact or
             omit to state any material fact necessary to make the statements

             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 same has become effective, (B) of any
             request by 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 Act or of the suspension by
             any state securities commission of 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, and (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

                                     - 4 -

             reasonable number of copies of the Prospectus (including each
             preliminary prospectus) and any 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 any, in connection with the offering and
             the sale of the Transfer Restricted Securities covered by the
             Prospectus or any amendment or supplement thereto;

                  (vii) prior to any offering of Transfer Restricted Securities,
             cooperate with the Holders in connection with the registration and
             qualification of the Transfer Restricted Securities under the
             securities or Blue Sky laws of such jurisdictions as reasonably
             requested and do any and all other acts or things necessary or
             advisable to enable the disposition in such jurisdictions of the
             Transfer Restricted Securities covered by the Shelf Registration
             Statement; provided, however, that the Company shall not be
             required to register or qualify as a foreign corporation where it
             is not now so qualified or to take any action that would subject it
             to the service of process in suits or to taxation, other than as to
             matters and transactions relating to the Shelf Registration
             Statement, in any jurisdiction where it is not now so subject;

             which the Common Stock is then listed;

                  (x) use its best efforts to cause the disposition of the
             Transfer Restricted Securities covered by the Shelf Registration
             Statement to be registered with or approved by such other
             governmental agencies or authorities as may be required to enable

             Transfer Restricted Securities;

                  (xi) use its best efforts to comply with all applicable rules
             and regulations of the Commission, and make generally available to

             statement meeting the requirements of Rule 158 (which need not be

             required, in the judgment of the Company, by the Act;

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

             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 Certificate Holder, then (A) the Company shall give
             written notice of such proposed filing to the Certificate Holder as
             soon as practicable (but in no event less than 30 days before the
             anticipated filing date), (B) such notice shall offer the
             Certificate Holder, 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 "Piggyback
             Registration Statement") to be available to permit the offer and
             sale, at the Certificate Holder's election, of some or all of the
             Transfer Restricted Securities owned by the Certificate Holder on
             the same terms and conditions as the Company's or such other
             holder's Common Stock (a "Piggyback Sale"), and (C) the Company
             shall otherwise take such reasonable actions as will enable the
             Certificate Holder to effect a 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 the Piggyback Registration Statement to
             permit the offer and sale of all Transfer Restricted Securities
             requested by the Certificate Holder 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 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 the Certificate Holder
             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 the Certificate Holder 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 Piggyback Registration
             Statement is to be underwritten, then the Certificate Holder making
             a request for a 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 Piggyback
             Registration Statement is to be on any other terms, then the
             Certificate Holder making a request for a 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. The Certificate Holder shall
             be permitted to withdraw all or part of the Certificate Holder's
             Transfer Restricted Securities from coverage by a Piggyback
             Registration Statement at any time prior to (but only prior to) the
             effective date thereof without prejudice to the rights of the
             Certificate Holder 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 the Certificate Holder has requested a Piggyback Sale shall
advise the Company in writing that (x) the size of the offering that the
Certificate Holder, the Company and any other holders intend to make or (y) the
kind of securities that the Certificate Holder, 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 the Certificate Holder
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 the
Certificate Holder, the proportion by which the amount of such Transfer
Restricted Securities intended to be

                                     - 8 -
<PAGE>   10

offered for the account of the Certificate Holder 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 Certificate Holder's rights to have the 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 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
Certificate Holder 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

                                     - 9 -
<PAGE>   11

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 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 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

                                     - 10 -
<PAGE>   12

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 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

                                     - 11 -

<PAGE>   13
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

reports (a) complied as to form in all material respects with the applicable

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

                                     - 12 -
<PAGE>   14

as may be noted therein and except, in the case of any unaudited statements, as
permitted by Form 10-Q promulgated under the Exchange Act.

         (d) Neither the execution and delivery of this Agreement nor compliance
with the terms and provisions of this Agreement will violate any law, statute,
rule or regulation of any governmental authority, or will on the Closing Date
conflict with or result in a breach of any of the terms, conditions or
provisions of any judgment, order, injunction, decree or ruling of any court or
governmental agency, authority to which the Company is subject or of any
agreement or instrument to which the Company is a party.

         (e) The execution, delivery and performance of this Agreement have been
duly and validly authorized and approved by all requisite corporate action on
the part of the Company. This Agreement has been, and the other agreements
contemplated hereby when executed and delivered will be, duly executed and
delivered by the Company and, assuming the due authorization, execution and
delivery hereof and thereof by the other parties hereto or thereto, this
Agreement constitutes and, when executed, each of the other agreements
contemplated hereby will constitute, a valid and binding obligation of the
Company, enforceable against the Company in accordance with its terms subject to
applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent
conveyance and similar laws affecting creditors' rights generally from time to
time and to general principles of equity.

         (f) There is no litigation, proceeding or investigation pending or, to
the knowledge of the Company threatened against or affecting the Company that
questions the validity or enforceability of this Agreement or any other
document, instrument or agreement to be executed and delivered by either the

         (g) No vote of the holders of any class or series of the Company's
capital stock or other voting securities is necessary to approve this Agreement
or the transactions contemplated hereby.

         (h) As of the Closing Date CEMI is solvent.

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 Certificate Holder 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 Certificate Holder 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

                                     - 13 -
<PAGE>   15

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 Certificate Holder, 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.

         (f) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail
(registered or certified, return receipt requested), telex, telecopier, or air
courier guaranteeing overnight delivery:

                  (i) if to a Holder, to the address set forth on the records of
             either the Registrar with respect to the Shares or The Depository
             Trust Company, as the case may be;

                  (ii) if to the Company: to Chesapeake Energy Corporation, 6100
             North Western Avenue, Oklahoma City, Oklahoma 73118, Attention:

             Attention: Connie S. Stamets; and

                  (iii) if to the Certificate Holder: to Paribas North America,
             Inc. 787 Seventh Avenue, New York, New York 10019, Attention: Mr.
             Albert Young or in any case to such other address as the Person to
             be notified may have requested in writing.

All such notices and communications shall be deemed to have been duly given: at
the time delivered by hand, if personally delivered; five (5) Business Days
after being deposited in the mail, postage prepaid, if mailed; when receipt is
acknowledged, if telecopied; and on the next business day, if timely delivered
to an air courier guaranteeing overnight delivery.

         (g) Successors and Assigns. This Agreement shall inure to the benefit
of and be binding upon the successors and assigns of each of the parties,
including without limitation and without the

                                     - 14 -
<PAGE>   16

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 Agreement. 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 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.

         (i) Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

         (j) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
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
Agreement, 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 the
Purchase Agreement, CEMI is obligated to cause the issuance of additional shares
of Common Stock or to pay additional cash to the Certificate Holder 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 the 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 Certificate Holder required to satisfy such
obligations under the Purchase Agreement.

SECTION 5. SHELF REGISTRATION PROCEDURES

     (a)  Procedures. In connection with the Shelf Registration Statement, the
          Company will:

               (i) use its best efforts to effect such registration to permit
          the sale of the Transfer Restricted Securities being sold in
          accordance with the intended method or methods of distribution thereof
          (as indicated in the information furnished to the Company pursuant to
          Section 4 hereof), and pursuant thereto the Company will prepare and
          file with the Commission a Shelf Registration Statement relating to
          the registration on any appropriate form under the Act, which form
          will 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 in accordance with the
          provisions hereof. Except for the Common Stock covered by that certain
          Registration Rights Agreement dated effective June 27, 2000, among the
          Company, Appaloosa Investment Limited Partnership I, Palomino Fund,
          Ltd., Tersk L.L.C., Oppenheimer Strategic Income Fund, Oppenheimer
          Champion Income Fund, Oppenheimer High Yield Fund, Oppenheimer
          Strategic Bond Fund/VA, Atlas Strategic Income Fund and that certain
          Registration Rights Agreement dated effective August 29, 2000 between
          the Company and Paribas North America, Inc. (collectively, the
          "Discount Noteholder Rights Agreement"), the Company will not be
          permitted to include in the Shelf Registration Statement any
          securities other than the Transfer Restricted Securities. If the
          registration of the sale of the Transfer Restricted Securities is an
          underwritten offering and other holders of unregistered Common Stock
          exercise piggy-back registration rights with respect to such
          underwritten offering, in the event the managing underwriter
          determines in its sole

                                      -4-
<PAGE>   5

          discretion that including all of the Common Stock requested to be
          included in such underwritten offering will jeopardize the success of
          the offering, unless the Company is legally obligated to cut back pro
          rata, the Common Stock requested to be included by the holders of such
          piggy-back registration rights will be excluded from such underwritten
          offering prior to any exclusion therefrom of any of the Transfer
          Restricted Securities.

               (ii) use its best efforts to keep such Shelf Registration
          Statement continuously effective and provide all requisite financial
          statements and any other information for the period specified in
          Section 3 of this Agreement. Upon the occurrence of any event that
          would cause any such Shelf Registration Statement or the Prospectus
          contained therein (i) to contain an untrue statement of a material
          fact or omit to state any material fact necessary to make the
          statements therein not misleading or (ii) not to be effective and
          usable for resale of Transfer Restricted Securities during the period
          required by this Agreement, the Company will subject to this Section 5
          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, and such other Rules
          as are applicable to the Prospectus, 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 same has become effective, (B) of any request by 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 Act or of the suspension by any state securities commission of the
          qualification of the Transfer Restricted Securities for offering or
          sale in any jurisdiction, or the initiation of any proceeding

                                      -5-
<PAGE>   6

          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, misleading.

               (v) subject to Section 5(a)(ii), if any fact or event
          contemplated by Section 5(iv)(D) above will 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 Prospectus (including each preliminary
          prospectus) and any 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 any, in
          connection with the offering and the sale of the Transfer Restricted
          Securities covered by the Prospectus or any amendment or supplement
          thereto.

               (vii) prior to any offering of Transfer Restricted Securities,
          cooperate with the Holders in connection with the registration and
          qualification of the Transfer Restricted Securities under the
          securities or Blue Sky laws of such jurisdictions as reasonably
          requested and do any and all other acts or things necessary or
          advisable to enable the disposition in such jurisdictions of the
          Transfer Restricted Securities covered by the Shelf Registration
          Statement; provided, however, that the Company will not be required to
          register or qualify as a foreign corporation where it is not now so
          qualified or to take any action that would subject it to the service
          of process in suits or to taxation, other than as to matters and
          transactions relating to the Shelf Registration Statement, in any
          jurisdiction where it is not now so subject.

               (viii) in connection with any sale of Transfer Restricted
          Securities that will result in such securities no longer being
          Transfer Restricted Securities, cooperate with the Holders to
          facilitate the timely preparation and delivery of certificates
          representing Transfer Restricted Securities to be sold and not bearing
          any restrictive legends.

               (ix) list all shares of Common Stock covered by the Shelf
          Registration Statement on the principal U.S. securities exchange on
          which the Common Stock is then listed.

               (x) use its best efforts to cause the disposition of the Transfer
          Restricted Securities covered by the Shelf Registration Statement to
          be registered with or

                                      -6-
<PAGE>   7

          approved by such other governmental agencies or authorities as may be
          required to enable the seller or sellers thereof to consummate the
          disposition of such Transfer Restricted Securities.

               (xi) use its best efforts to comply with all applicable rules and
          regulations of the Commission, and make generally available to its
          security holders with regard to the Shelf Registration Statement, as
          soon as practicable, a consolidated earnings statement meeting the
          requirements of Rule 158 (which need not be audited) covering a
          twelve-month period beginning after the Effective Date (as such term
          is defined in paragraph (c) of Rule 158 under the Act).

               (xvii) provide the Holders with a reasonable opportunity to
          review and comment on any registration statement to be filed pursuant
          to this Agreement prior to the filing thereof with the Commission, and
          will make all changes thereto as any Holder may request in writing to
          the extent such changes are required, in the judgment of the Company,
          by the Act.

               (xviii) use best efforts to obtain the withdrawal of any order
          suspending the effectiveness of such registration statement, or the
          lifting of any suspension of the qualification (or exemption from
          qualification) of any of the Transfer Restricted Securities for sale
          in any jurisdiction, at the earliest possible moment.

               (xix) use its best efforts to furnish to each Holder and to each
          managing underwriter, if any, a signed counterpart, addressed to such
          Holder or such underwriter, if any, of (i) an opinion or opinions of
          counsel to the Company and (ii) a comfort letter or comfort letters
          from the Company=s independent public accountants pursuant to SAS 72,
          each in customary form and covering such matters of the type
          customarily covered by opinions or comfort letters, as the case may
          be, as such Holder or the managing underwriter reasonably requests.

               (xx) enter into customary agreements (including underwriting
          agreements in customary form, which will include "lock-up" obligations
          as may be requested by the managing underwriters, not to exceed 90
          days in duration, but excluding shares that may be issued pursuant to
          benefit plans or in connection with mergers or acquisitions) and take
          such other actions (including using its reasonable efforts to make
          such domestic road show presentations and otherwise engaging in such
          reasonable marketing support in connection with any underwritten
          offering, including without limitation the obligation to make its
          executive officers available for such purpose of so requested by the
          selling Holder (a "Road Show")) as are reasonably requested by any
          selling Holder in order to expedite or facilitate the sale of any
          Transfer Restricted Securities covered by a registration statement
          pursuant to an underwritten offering in accordance herewith.

               (xxi) offer Lehman the opportunity to manage any underwritten
          offering under this Agreement, subject to the reasonable consent of
          the Holders of a majority of the Transfer Restricted Securities to be
          included in such registration.

                                      -7-
<PAGE>   8

     (b) Restrictions on Holders. Each Holder agrees by acquisition of a
Transfer Restricted Security that, upon receipt of (i) the notice referred to in
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
substantially 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"). The aggregate suspension pursuant to clause (iii) above will 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 90 th 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

                                      -8-

<PAGE>   9

          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 or other
          holders of Notes or for the owners of Common Stock covered by Discount
          Noteholders Rights Agreement), then (A) the Company will 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 will 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 will
          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 will 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 will take such actions
          as will 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 will 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, will 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 will
          not be permitted to make any other offering in connection with such
          registration. If the offering pursuant to such Noteholder 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 will not be permitted to make an underwritten offering in
          connection with such registration. Each Noteholder will be permitted
          to withdraw all or part of such Noteholder=s Transfer Restricted
          Securities

                                      -9-
<PAGE>   10

          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 will 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 will 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 will 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 will 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) will 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 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.

                                      -10-
<PAGE>   11

     . 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, its employees, its agents and underwriters 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.

                                      -11-
<PAGE>   12

     (c) In case any action will 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 will promptly notify the Person against whom such
indemnity may be sought (the "indemnifying party") in writing and the
indemnifying party will assume the defense of such action, including the
employment of counsel reasonably satisfactory to the indemnified party and the
payment of all fees 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 will 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, will be at the expense of the Holder). Any
indemnified party will 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 will be at the expense of the indemnified party unless (i) the
employment of such counsel will have been specifically authorized in writing by
the indemnifying party, (ii) the indemnifying party will 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 will 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 will not have the right to assume the defense of such action
on behalf of the indemnified party). In any such case, the indemnifying party
will 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 will be reimbursed as
they are incurred. Such firm will 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 will 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 will 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 will have failed to comply with
such reimbursement request. No indemnifying party will, 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, will

                                      -12-
<PAGE>   13

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,
will be determined by reference to, among other things, whether the 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 will 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 will 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) will 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. 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 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. The Company and each of the Holders
hereby agree that: (a) the terms of this Agreement and the registration rights
granted hereunder are subject to the terms and conditions of the Discount
Noteholder Rights Agreement; and (b) the registration rights granted under the
Discount Noteholders Rights Agreement are prior to the rights granted under this
Agreement.

     (c) No Piggybacks on Shelf Registration Statement. After the date of this
Agreement the Company will 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 and the Common Stock covered by the Discount
Noteholders Rights Agreement.

     (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 parties agree that: (a) each
representation, warranty, covenant and agreement under this Agreement is between
the Company, on the one hand, and each Holder, on the other hand; and (b) no
Holder will be deemed a direct or indirect beneficiary of any representation,
warranty, covenant or agreement by or between the Company and any other Holder.

     (f) Notices. All notices and other communications provided for or permitted
hereunder will be made in writing by hand-delivery, first-class mail (registered
or certified, return receipt requested), telex, telecopier, or air courier
guaranteeing overnight delivery:

               (i) if to a Holder, to the address set forth on the records of
          either the Registrar with respect to the Shares or The Depository
          Trust Company, as the case may be;

          by the Noteholder; or in any case to such other address as the Person
          to be notified may have requested in writing.

     All such notices and communications will be deemed to have been duly given:
at the time delivered by hand, if personally delivered; five (5) Business Days
after being deposited in the mail, postage prepaid, if mailed; when receipt is
acknowledged, if telecopied; and on the next business day, if timely delivered
to an air courier guaranteeing overnight delivery.

     (g) Successors and Assigns. This Agreement will inure to the benefit 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 will 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 will acquire Transfer Restricted
Securities in any manner, whether by operation of law or otherwise, such
Transfer Restricted Securities will be held subject to all of the terms of this
Agreement, and by taking and holding such Transfer Restricted Securities such
Person will 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 will 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 will be deemed to be an original and all of which taken
together will constitute one and the same agreement.

     (i) Headings. The headings in this Agreement are for convenience of
reference only and will not limit or otherwise affect the meaning hereof.

     (j) Governing Law. THIS AGREEMENT WILL BE GOVERNED BY AND CONSTRUED IN
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 will 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

                                      -15-

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.

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