    2   Registration Under the Securities Act.

    (a) Except as set forth in Section 2(b) below, the Company agrees to use its
reasonable best efforts to file under the Securities Act, as soon as
practicable, but no later than 90 days after the Closing, a registration
statement relating to an offer to exchange (such registration statement, an
"Exchange Registration Statement", and such offer, an "Exchange Offer") any and
all of the Securities for a like aggregate principal amount at maturity of debt
securities issued by the Company, which debt securities are substantially
identical to the Securities of such Series, respectively, (and are entitled to
the benefits of a trust indenture which is substantially identical to the
Indenture and which has been qualified under the Trust Indenture Act), except
that they have been registered pursuant to an effective registration statement
under the Securities Act and do not contain provisions for the additional
interest contemplated in Section 2(c) below (such new debt securities
hereinafter called "Exchange Securities"). The Company agrees to use its
reasonable best efforts to cause such Exchange Registration Statement to become
effective under the Securities Act as soon as practicable after the Closing. The
Exchange Offer will be registered under the Securities Act on the appropriate
form and will comply with all applicable tender offer rules and regulations
under the Exchange Act. The Company further agrees to use its reasonable best
efforts to commence the Exchange Offer promptly after such registration
statement has become effective, hold such Exchange Offer open for at least 20
business days and issue Exchange Securities for all Registrable Securities that
have been properly tendered and not withdrawn on or prior to the expiration of
such Exchange Offer.  Such Exchange Offer will be deemed to have been
"completed" only if the securities received by holders other than Restricted
Holders in such Exchange Offer for such Registrable Securities are, upon
receipt, transferable by each such holder without need for further compliance
with Section 5 of the Securities Act and the Exchange Act (except for the
requirement to deliver a prospectus included in the Exchange Registration
Statement applicable to resales by any broker-dealer of Exchange Securities
received by such broker-dealer pursuant to an Exchange Offer in exchange for
Registrable Securities other than those acquired by the broker-dealer directly
from the Company), and without material restrictions under the blue sky or
securities laws of a substantial majority of the States of the United States of
America. Such Exchange Offer shall be deemed to have been completed upon the
earlier to occur of (i) the Company having exchanged the applicable Exchange
Securities for all outstanding Registrable Securities of such Series pursuant to
the Exchange Offer and (ii) the Company having exchanged, pursuant to such
Exchange Offer, Exchange Securities for all Registrable Securities that have
been properly tendered and not withdrawn before the expiration of such Exchange
Offer, which shall be on a date that is at least 20 business days following the
commencement of such Exchange Offer. The Company agrees (x) to include in the
Exchange Registration Statement a prospectus for use in connection with any
resales of such Exchange Securities by a broker-dealer, other than resales of
such Exchange Securities received by a broker-dealer pursuant to an Exchange
Offer in exchange for

                                       4

 
Registrable Securities acquired by the broker-dealer directly from the Company,
and (y) to keep such Exchange Registration Statement effective for a period (the
"Resale Period") beginning when such Exchange Securities are first issued in
such Exchange Offer and ending upon the earlier of the expiration of the 90th
day after such Exchange Offer has been completed or such time as such broker-
dealers no longer own any Registrable Securities. With respect to such Exchange
Registration Statement, each broker-dealer that holds such Exchange Securities
received in such Exchange Offer in exchange for Registrable Securities not
acquired by it directly from the Company shall have the benefit of the rights of
indemnification and contribution set forth in Sections 6(a), (c), (d) and (e)
hereof.

    (b) If, prior to the time the Exchange Offer is completed, existing
Commission interpretations are changed such that the Securities received by
holders other than Restricted Holders in such Exchange Offer for Registrable
Securities are not or would not be, upon receipt, transferable by each such
holder without need for further compliance with Section 5 of the Securities Act
(except for the requirement to deliver a prospectus included in the Exchange
Registration Statement applicable to resales by broker-dealers of Exchange
Securities received by such broker-dealer pursuant to an Exchange Offer in
exchange for Registrable Securities other than those acquired by the broker-
dealer directly from the Company) or if such Exchange Offer has not been
consummated within 225 days following the Closing, in lieu of conducting the
Exchange Offer contemplated by Section 2(a) the Company shall use its reasonable
best efforts to file under the Securities Act as soon as practicable, but no
later than 45 days after the date on which the obligation to file such "shelf"
registration statement arises, a "shelf" registration statement providing for
the registration of, and the sale on a continuous or delayed basis by the
holders of, all of the Registrable Securities, pursuant to Rule 415 or any
similar rule that may be adopted by the Commission (such filing, a "Shelf
Registration" and such registration statement, a "Shelf Registration
Statement").  In addition, in the event that the Purchasers shall not have
resold all of the Securities initially purchased by them from the Company
pursuant to the Notes Purchase Agreement prior to the consummation of the
applicable Exchange Offer, the Company shall file under the Securities Act as
soon as practicable a Shelf Registration Statement in respect such Securities.
The Company agrees to use its reasonable best efforts (i) to cause the Shelf
Registration Statement to become or be declared effective no later than 105 days
following the date on which the obligation to file such Shelf Registration
Statement arose and to keep such Shelf Registration Statement continuously
effective (subject to the provisions of the last sentence of this Section 3(b))
in order to permit the prospectus forming a part thereof to be usable by holders
for resales of such Registrable Securities for a period ending on the earlier of
the second anniversary of the effective date thereof or such time as there are
no longer any Registrable Securities outstanding, provided, however, that no
holder shall be entitled to be named as a selling securityholder in such Shelf
Registration Statement or to use the prospectus forming a part thereof for
resales of applicable Registrable Securities unless such holder is an Electing
Holder, and (ii) after the Effective Time of such Shelf Registration Statement,
promptly upon the request of any holder of Registrable Securities that is not
then an Electing Holder, to take any action reasonably necessary to enable such

                                       5

 
holder to use the prospectus forming a part thereof for resales of Registrable
Securities, including, without limitation, any action necessary to identify such
holder as a selling securityholder in the Shelf Registration Statement,
provided, however, that nothing in this clause (ii) shall relieve any such
holder of the obligation to return a completed and signed Notice and
Questionnaire to the Company in accordance with Section 3(d)(iii) hereof. The
Company further agrees (subject to the provisions of the last sentence of this
Section 3(b)) to supplement or make amendments to the Shelf Registration
Statement, as and when required by the rules, regulations or instructions
applicable to the registration form used by the Company for such Shelf
Registration Statement or by the Securities Act or rules and regulations
thereunder for shelf registration, and the Company agrees to furnish to each
Electing Holder copies of any such supplement or amendment prior to its being
used or promptly following its filing with the Commission.  Notwithstanding the
requirement to keep such Shelf Registration Statement continuously effective,
the Company may suspend the effectiveness of a Shelf Registration Statement for
up to 45 consecutive days once during any 90-day period and up to three times
during any 365-day period, but no more than an aggregate of 90 days during any
365-period if, (a)(i) an event occurs and is continuing as a result of which the
Shelf Registration Statement would, in the Company's good faith judgment,
contain an untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements therein not misleading and (ii) the
Company determines in good faith that the disclosure of such event at such time
would have a material adverse effect on the business, operations or prospects of
the Company or (b) the disclosure otherwise relates to a pending material
business transaction or other corporate development.

    (c) In the event that (i) the Company has not filed the Exchange
Registration Statement or Shelf Registration Statement on or before the date on
which such registration statement is required to be filed pursuant to Section
2(a) or 2(b), respectively, or (ii) such Exchange Registration Statement has not
become effective or been declared effective by the Commission within 180 days of
the Closing, or (iii) such Shelf Registration Statement has not become effective
within 105 days of the date on which the obligation to file such Shelf
Registration Statement arose, or (iv) the Exchange Offer has not been completed
within 30 business days after the effectiveness deadline of the Exchange
Registration Statement relating to such Exchange Offer (if such Exchange Offer
is then required to be made) or (v) any Exchange Registration Statement or Shelf
Registration Statement required by Section 2(a) or 2(b) hereof is filed and
declared effective but shall thereafter either be withdrawn by the Company or
shall become subject to an effective stop order issued pursuant to Section 8(d)
of the Securities Act suspending the effectiveness of such registration
statement (except as specifically permitted herein) without being succeeded
within 30 days by an additional registration statement filed and declared
effective (each such event referred to in clauses (i) through (v), a
"Registration Default" and each period during which a Registration Default has
occurred and is continuing, a "Registration Default Period"), then, as
liquidated damages for such Registration Default, notwithstanding the provisions
of Section 9(b), special cash interest ("Special Interest"), in addition to Base
Interest, shall accrue and be payable at a per annum rate of 0.25%.  If the
Company has not completed the Exchange Offer by the

                                       6

 
270th day following the Closing (or, if applicable, the Shelf Registration has
not become effective by the 150th day after the obligation to file it arose),
the Special Interest shall accrue and be payable at a per annum rate of 0.5%
until the Company has completed such Exchange Offer (or until such Shelf
Registration has become effective).

    (d) The Company shall take all reasonable actions necessary or advisable to
be taken by it to ensure that the transactions contemplated herein are effected
as so contemplated.

    (e) Any reference herein to a registration statement as of any time shall be
deemed to include any document incorporated, or deemed to be incorporated,
therein by reference as of such time and any reference herein to any post-
effective amendment to a registration statement as of any time shall be deemed
to include any document incorporated, or deemed to be incorporated, therein by
reference as of such time.

     3. Registration Procedures.

     If the Company files a registration statement pursuant to Section 2(a) or
Section 2(b), the following provisions shall apply:

    (a) If the Company files a registration statement pursuant to Section 2(a)
or Section 2(b), at or before the Effective Time of any Exchange Offer or any
Shelf Registration, as the case may be, the Company shall qualify the Indenture
under the Trust Indenture Act.

    (b) If the Company files a registration statement pursuant to Section 2(a)
or Section 2(b), in the event that such qualification would require the
appointment of a new trustee under the Indenture, the Company shall appoint a
new trustee thereunder pursuant to the applicable provisions of the Indenture.

    (c) In connection with the Company's obligations with respect to the
registration of Exchange Securities as contemplated by Section 2(a) (an
"Exchange Registration"), if applicable, the Company shall, as soon as
practicable (or as otherwise specified):

          (i) use its reasonable best efforts to prepare and file with the
     Commission, as soon as practicable but no later than 90 days after the
     Closing, an Exchange Registration Statement on any form which may be
     utilized by the Company and which shall permit the Exchange Offer and
     resales of Exchange Securities by broker-dealers during the Resale Period
     to be effected as contemplated by Section 2(a), and use its reasonable best
     efforts to cause such Exchange Registration Statement to become effective
     as soon as practicable thereafter;

          (ii) as soon as practicable use its reasonable best efforts to prepare
     and file with the Commission such amendments and supplements to such
     Exchange

                                       7

 
     Registration Statement and the prospectus included therein as may be
     necessary to effect and maintain the effectiveness of such Exchange
     Registration Statement for the periods and purposes contemplated in Section
     2(a) hereof and as may be required by the applicable rules and regulations
     of the Commission and the instructions applicable to the form of such
     Exchange Registration Statement, and promptly provide each broker-dealer
     holding Exchange Securities with such number of copies of the prospectus
     included therein (as then amended or supplemented), in conformity in all
     material respects with the requirements of the Securities Act and the Trust
     Indenture Act and the rules and regulations of the Commission thereunder,
     as such broker-dealer reasonably may request prior to the expiration of the
     Resale Period, for use in connection with resales of such Exchange
     Securities;

          (iii) promptly notify each broker-dealer that has requested or
     received copies of the prospectus included in such registration statement,
     and confirm such advice in writing, (A) when such Exchange Registration
     Statement or the prospectus included therein or any prospectus amendment or
     supplement or post-effective amendment has been filed (delivery of a copy
     of the filed Exchange Registration Statement or amendment to the Initial
     Purchasers shall be sufficient notice for purposes of this clause (A)),
     and, with respect to such Exchange Registration Statement or any post-
     effective amendment, when the same has become effective, (B) of the
     issuance by the Commission of any stop order suspending the effectiveness
     of such Exchange Registration Statement or the initiation of any
     proceedings for that purpose, (C) of the receipt by the Company of any
     notification with respect to the suspension of the qualification of the
     Exchange Securities for sale in any jurisdiction or the initiation of any
     proceeding for such purpose or (D) at any time during the Resale Period
     when a prospectus is required to be delivered under the Securities Act,
     that such Exchange Registration Statement, prospectus, prospectus amendment
     or supplement or post-effective amendment does not conform in all material
     respects to the applicable requirements of the Securities Act and the Trust
     Indenture Act and the rules and regulations of the Commission thereunder or
     contains an untrue statement of a material fact or omits to state a
     material fact required to be stated therein or necessary to make the
     statements therein not misleading in light of the circumstances then
     existing;

          (iv) in the event that the Company would be required, pursuant to
     Section 3(c)(iii)(D) above, to notify any broker-dealers holding Exchange
     Securities, without unreasonable delay prepare and furnish to each such
     holder a reasonable number of copies of a prospectus supplemented or
     amended so that, as thereafter delivered to purchasers of such Exchange
     Securities during the Resale Period, such prospectus shall conform in all
     material respects to the applicable requirements of the Securities Act and
     the Trust Indenture Act and the rules and regulations of the Commission
     thereunder and shall not contain an untrue statement of a material fact or
     omit to state a material fact required to be stated

                                       8

     of the circumstances then existing;

          (v) use its reasonable best efforts to (A) register or qualify the
     Exchange Securities under the securities laws or blue sky laws of such
     jurisdictions as are contemplated by Section 2(a), if such registration or
     qualification is required by such laws, no later than the commencement of
     the Exchange Offer, (B) keep such registrations or qualifications in effect
     and comply with such laws so as to permit the continuance of offers, sales
     and dealings therein in such jurisdictions until the expiration of the
     Resale Period and (C) take any and all other actions as may be reasonably
     necessary or advisable to enable each broker-dealer holding such Exchange
     Securities to consummate the disposition thereof in such jurisdictions;
     provided, however, that the Company shall not be required for any such
     purpose to (1) qualify as a foreign corporation in any jurisdiction wherein
     it would not otherwise be required to qualify but for the requirements of
     this Section 3(c)(vi), (2) consent to general service of process in any
     such jurisdiction or (3) make any changes to its certificate of
     incorporation or by-laws or any agreement between it and its stockholders;

          (vi) use its reasonable best efforts to obtain the consent or approval
     of each governmental agency or authority, whether federal, state or local,
     which may be required to effect the Exchange Registration, the Exchange
     Offer and the offering and sale of the Exchange Securities by broker-
     dealers during the Resale Period;

          (vii) provide a CUSIP number for all Exchange Securities, not later
     than the Effective Time;

          (viii) comply with all applicable rules and regulations of the
     Commission, and make generally available to its securityholders as soon as
     practicable but no later than eighteen months after the effective date of
     such Exchange Registration Statement, an earning statement of the Company
     and its subsidiaries complying with Section 11(a) of the Securities Act
     (including, at the option of the Company, Rule 158 thereunder);

          (ix) prior to the consummation of the Exchange Offer, cause to be
     delivered to the Trustee for the benefit of holders an opinion of outside
     counsel to the effect that the Exchange Securities when issued and
     authenticated in accordance with the terms of the Indenture, the
     Registration Rights Agreement and the Exchange Offer, will constitute valid
     and legally binding obligations of the Company entitled to the benefits
     provided by the Indenture.

    (d) In connection with the Company's obligations with respect to any Shelf
Registration, if applicable, the Company shall, as soon as practicable (or as
otherwise specified):

                                       9

 
          (i) use its reasonable best efforts to prepare and file with the
     Commission, as soon as practicable but in any case within the time periods
     specified in Section 2(b), a Shelf Registration Statement on any form which
     may be utilized by the Company and which shall register all of the
     Registrable Securities for resale by the holders thereof in accordance with
     such method or methods of disposition as may be specified by such of the
     holders (subject to clause (xv) below) as, from time to time, may be

     Effective Time, and no holder shall be entitled to use the prospectus
     forming a part thereof for resales of such Registrable Securities at any
     time, unless such holder has returned a completed and signed Notice and
     Questionnaire to the Company by the deadline for response set forth
     therein; provided, however, holders of such Registrable Securities shall
     have at least 28 calendar days from the date on which the Notice and
     Questionnaire is first mailed to such holders to return a completed and
     signed Notice and Questionnaire to the Company;

          (iii)  after the Effective Time of the Shelf Registration Statement,
     upon the request of any holder of Registrable Securities that is not then
     an Electing Holder, promptly send a Notice and Questionnaire to such
     holder; provided that the Company shall not be required to take any action
     to name such holder as a selling securityholder in such Shelf Registration
     Statement or to enable such holder to use the prospectus forming a part
     thereof for resales of such Registrable Securities until such holder has
     returned a completed and signed Notice and Questionnaire to the Company;

          (iv) as soon as practicable prepare and file with the Commission such
     amendments and supplements to such Shelf Registration Statement and the
     prospectus included therein as may be necessary to effect and maintain the

     combination of such methods, and which shall not bear any restrictive
     legends; and, in the case of an underwritten offering, enable such

agent, if any, and the managing underwriters, if any, the Company shall without
delay prepare and furnish to each of the Electing Holders, to each placement or

discontinue the disposition of Registrable Securities pursuant to the Shelf
Registration Statement until such Electing Holder shall have received copies of
such amended or supplemented prospectus, and if so directed by the Company, such
Electing Holder shall deliver to the Company (at the Company's expense) all
copies, other than permanent file copies, then in such Electing Holder's
possession of the prospectus covering such Registrable Securities at the time of
receipt of such notice.

    (f) In the event of a Shelf Registration, in addition to the information

Company may require such Electing Holder to furnish to the Company such
additional information regarding such Electing Holder and such Electing Holder's
intended method of distribution of Registrable Securities as may be required in
order to comply with the Securities Act. Each such Electing Holder agrees to
notify the Company as promptly as practicable of any inaccuracy or change in
information previously furnished by such Electing Holder to the Company or of
the occurrence of any event in either case as a result of which any prospectus
relating to such Shelf Registration contains or would contain an untrue
statement of a material fact regarding such Electing Holder or such Electing
Holder's intended method of disposition of such Registrable Securities or omits
to state any material fact regarding such Electing Holder or such Electing
Holder's intended method of disposition of such Registrable Securities required
to be stated therein or necessary to make the statements therein not misleading
in light of the circumstances then existing, and promptly to furnish to the
Company any additional information required to correct and update any previously
furnished information or required so that such prospectus shall not contain,

Securities, an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing.

    (g) Until the expiration of two years after the Closing, the Company will
not, and will not permit any of its "affiliates" (as defined in Rule 144) to,
resell any of the Securities that have been reacquired by any of them except
pursuant to an effective registration statement under the Securities Act.

                                      19

 
statements therein not misleading, and the Company shall, and it hereby agrees
to, reimburse such holder, such Electing Holder, such agent and such underwriter
for any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such action or claim as such expenses are
incurred; provided, however, that the Company shall not be liable to any such
person in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in such registration statement,
or preliminary, final or summary prospectus, or amendment or supplement thereto,
in reliance upon and in conformity with written information furnished to the
Company by such person expressly for use therein;

    (b) Indemnification by the Electing Holders and any Agents and Underwriters.
The Company may require, as a condition to including any Registrable Securities
in any registration statement filed pursuant to Section 2(b) hereof and to
entering into any underwriting agreement with respect thereto, that the Company
shall have received an undertaking reasonably satisfactory to it from the
Electing Holder of such Registrable Securities and from each underwriter named
in any such underwriting agreement, severally and not jointly, to (i) indemnify
and hold harmless the Company, and all other holders of Registrable Securities,
against any losses, claims, damages or liabilities to which the Company or such
other holders of Registrable Securities may become subject, under the Securities
Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon an untrue statement
or alleged untrue statement of a material fact contained in such registration
statement, or any preliminary, final or summary prospectus contained therein or
furnished by the Company to any such Electing Holder, agent or underwriter, or
any amendment or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, in
each case to the extent, but only to the extent, that such untrue statement or
alleged untrue statement or omission or alleged omission was made in reliance
upon and in conformity with written information furnished to the Company by such
Electing Holder or underwriter expressly for use therein, and (ii) reimburse the
Company for any legal or other expenses reasonably incurred by the Company in
connection with investigating or defending any such action or claim as such
expenses are incurred; provided, however, that no such Electing Holder shall be
required to undertake liability to any person under this Section 6(b) for any
amounts in excess of the dollar amount of the proceeds to be received by such
Electing Holder from the sale of such Electing Holder's Registrable Securities
pursuant to such registration.

    (c) Notices of Claims, Etc. Promptly after receipt by an indemnified party
under subsection (a) or (b) above of written notice of the commencement of any
action, such indemnified party shall, if a claim in respect thereof is to be
made against an indemnifying party pursuant to the indemnification provisions of
or contemplated by this Section 6, notify such indemnifying party in writing of
the commencement of such action; but the omission so to notify the indemnifying
party shall not relieve it from any liability which it may have to any
indemnified party other than under the indemnification

                                      20

 
provisions of or contemplated by Section 6(a) or 6(b) hereof. In case any such
action shall be brought against any indemnified party and it shall notify an
indemnifying party of the commencement thereof, such indemnifying party shall be
entitled to participate therein and, to the extent that it shall wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party (who
shall not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, such
indemnifying party shall not be liable to such indemnified party for any legal
expenses of other counsel or any other expenses, in each case subsequently
incurred by such indemnified party, in connection with the defense thereof other
than reasonable costs of investigation. No indemnifying party shall, without the
written consent of the indemnified party, effect the settlement or compromise
of, or consent to the entry of any judgment with respect to, any pending or
threatened action or claim in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified party is an actual or
potential party to such action or claim) unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability arising out of such action or claim 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 any indemnified party.

    (d) Contribution. If for any reason the indemnification provisions
contemplated by Section 6(a) or Section 6(b) are unavailable to or insufficient
to hold harmless an indemnified party in respect of any losses, claims, damages
or liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative fault of the indemnifying party and the indemnified party in connection
with the statements or omissions which resulted in such losses, claims, damages
or liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations. The relative fault of such indemnifying party and
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by
such indemnifying party or by such indemnified party, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The parties hereto agree that it would not be just
and equitable if contributions pursuant to this Section 6(d) were determined by
pro rata allocation (even if the holders or any agents or underwriters or all of
them 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 this Section 6(d). The amount paid or payable by an indemnified party as a
result of the losses, claims, damages, or liabilities (or actions in respect
thereof) referred to above shall be deemed to include any legal or other fees or
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 6(d), no holder shall be required to contribute any
amount in excess of the amount by which the dollar amount of the proceeds
received by such

                                      21

 
holder from the sale of any Registrable Securities (after deducting any fees,
discounts and commissions applicable thereto) exceeds the amount of any damages
which such holder has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission, and no underwriter
shall be required to contribute any amount in excess of the amount by which the
total price at which the Registrable Securities underwritten by it and
distributed to the public were offered to the public exceeds the amount of any
damages which such underwriter 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 Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. The holders' and any
underwriters' obligations in this Section 6(d) to contribute shall be several in
proportion to the principal amount at maturity of Registrable Securities
registered or underwritten, as the case may be, by them and not joint.

    (e) The obligations of the Company under this Section 6 shall be in addition
to any liability which the Company may otherwise have and shall extend, upon the
same terms and conditions, to each officer, director and partner of each holder,
agent and underwriter and each person, if any, who controls any holder, agent or
underwriter within the meaning of the Securities Act; and the obligations of the
holders and any agents or underwriters contemplated by this Section 6 shall be
in addition to any liability which the respective holder, agent or underwriter
may otherwise have and shall extend, upon the same terms and conditions, to each
officer and director of the Company (including any person who, with his consent,
is named in any registration statement as about to become a director of the
Company) and to each person, if any, who controls the Company within the meaning
of the Securities Act.

    7.  Underwritten Offerings.

    (a) Selection of Underwriters. If any of the Registrable Securities covered
by the Shelf Registration are to be sold pursuant to an underwritten offering,
the managing underwriter or underwriters thereof shall be designated by Electing
Holders holding at least a majority in aggregate principal amount at maturity of
the  Registrable Securities to be included in such offering, provided that such
designated managing underwriter or underwriters is or are reasonably acceptable
to the Company.

    (b) Participation by Holders. Each holder of Registrable Securities hereby
agrees with each other such holder that no such holder may participate in any
underwritten offering hereunder unless such holder (i) agrees to sell such
holder's Registrable Securities on the basis provided in any underwriting
arrangements approved by the persons entitled hereunder to approve such
arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements.

    8.  Rule 144.

                                      22

 
     The Company covenants to the holders of Registrable Securities that to the
extent it shall be required to do so under the Exchange Act, the Company shall
timely file the reports required to be filed by it under the Exchange Act or the
Securities Act (including the reports under Section 13 and 15(d) of the Exchange
Act referred to in subparagraph (c)(1) of Rule 144 adopted by the Commission
under the Securities Act) and the rules and regulations adopted by the
Commission thereunder, and shall take such further action as any holder of
Registrable Securities may reasonably request, all to the extent required from
time to time to enable such holder to sell Registrable Securities without
registration under the Securities Act within the limitations of the exemption
provided by Rule 144 under the Securities Act, as such Rule may be amended from
time to time, or any similar or successor rule or regulation hereafter adopted
by the Commission.

    9.  Miscellaneous.

Agreement.

    (b) Specific Performance. The parties hereto acknowledge that there would be
no adequate remedy at law if the Company fails to perform any of its obligations
hereunder and that the Purchasers and the holders from time to time of the
Registrable Securities may be irreparably harmed by any such failure, and
accordingly agree that the Purchasers and such holders, in addition to any other
remedy to which they may be entitled at law or in equity, shall be entitled to
compel specific performance of the obligations of the Company under this
Exchange and Registration Rights Agreement in accordance with the terms and
conditions of this Exchange and Registration Rights Agreement, in any court of
the United States or any state thereof having jurisdiction.

Registration Rights Agreement shall be binding upon, shall inure to the benefit
of and shall be enforceable by the parties hereto and the holders from time to
time of the Registrable Securities and the respective successors and assigns of
the parties hereto and such holders. In the event that any transferee of any
holder of Registrable Securities shall

acquire Registrable Securities, in any manner, whether by gift, bequest,
purchase, operation of law or otherwise, such transferee shall, without any
further writing or action of any kind, be deemed a beneficiary hereof for all
purposes and such Registrable Securities shall be held subject to all of the
terms of this Exchange and Registration Rights Agreement, and by taking and
holding such Registrable Securities such transferee shall be entitled to receive
the benefits of, and be conclusively deemed to have agreed to be bound by all of
the applicable terms and provisions of this Exchange and Registration Rights
Agreement. If the Company shall so request, any such successor, assign or

subject to all of the applicable terms hereof.

     (e) Survival. The respective indemnities, agreements, representations,
warranties and each other provision set forth in this Exchange and Registration
Rights Agreement or made pursuant hereto shall remain in full force and effect
regardless of any investigation (or statement as to the results thereof) made by
or on behalf of any holder of Registrable Securities, any director, officer or
partner of such holder, any agent or underwriter or any director, officer or
partner thereof, or any controlling person of any of the foregoing, and shall
survive delivery of and payment for the Registrable Securities pursuant to the
Notes Purchase Agreement and the transfer and registration of Registrable
Securities by such holder and the consummation of any Exchange Offer.

Rights Agreement and shall not affect in any way the meaning or interpretation
of this Exchange and Registration Rights Agreement.

Agreement and the other writings referred to herein (including the Indenture and
the form of Securities) or delivered pursuant hereto which form a part hereof
contain the entire understanding of the parties with respect to its subject
matter. This Exchange and Registration Rights Agreement supersedes all prior
agreements and understandings between the parties with respect to its subject
matter. This Exchange and Registration Rights Agreement may be amended and the
observance of any term of this Exchange and Registration Rights Agreement may be
waived (either generally or in a particular instance and either retroactively or
prospectively) only by a written instrument duly executed by the Company and the
holders of at least a majority in aggregate principal amount at maturity of each
Series of the Registrable Securities at the time outstanding. Each holder of any
Registrable Securities at the time or thereafter outstanding shall be bound by
any amendment or waiver effected pursuant to this Section 9(h), whether or not
any notice,

                                       24

 
writing or marking indicating such amendment or waiver appears on such
Registrable Securities or is delivered to such holder.

     (i) Inspection. For so long as this Exchange and Registration Rights
Agreement shall be in effect, this Exchange and Registration Rights Agreement
and a complete list of the names and addresses of all the holders of Registrable
Securities shall be made available for inspection and copying on any business
day by any holder of Registrable Securities of the same Series for proper
purposes only (which shall include any purpose related to the rights of the
holders of Registrable Securities under the Securities, the Indenture and this
Agreement) at the offices of the Company at the address thereof set forth in
Section 9(c) above and at the office of the Trustee under the Indenture.

respective counterparts shall together constitute one and the same instrument.

     Agreed to and accepted as of the date referred to above.

                                    (Date)


     Reference is hereby made to the Exchange and Registration Rights Agreement
(the "Exchange and Registration Rights Agreement") between Clark Refining &
Marketing, Inc. (the "Company") and the Purchasers named therein. Pursuant to
the Exchange and Registration Rights Agreement, the Company has filed with the
United States Securities and Exchange Commission (the "Commission") a
registration statement on Form S-1 or S-3 (the "Shelf Registration Statement")
for the registration and resale under Rule 415 of the Securities Act of 1933, as
amended (the "Securities Act"), of the Company's 8 5/8% Senior Notes due 2008
(the "Securities"). A copy of the Exchange and Registration Rights Agreement is
attached hereto. All capitalized terms not otherwise defined herein shall have
the meanings ascribed thereto in the Exchange and Registration Rights Agreement.

     Each beneficial owner of Registrable Securities (as defined below) is
entitled to have the Registrable Securities beneficially owned by it included in
the Shelf Registration Statement. In order to have Registrable Securities
included in the Shelf Registration Statement, this Notice of Registration
Statement and Selling Securityholder Questionnaire ("Notice and Questionnaire")
must be completed, executed and delivered to the Company's counsel at the
address set forth herein for receipt ON OR BEFORE [DEADLINE FOR RESPONSE].
Beneficial owners of Registrable Securities who do not complete, execute and
return this Notice and Questionnaire by such date (i) will not be named as
selling securityholders in the Shelf Registration Statement and (ii) may not use
the Prospectus forming a part thereof for resales of Registrable Securities.

     Certain legal consequences arise from being named as a selling
securityholder in the Shelf Registration Statement and related Prospectus.
Accordingly, holders and beneficial owners of Registrable Securities are advised
to consult their own securities law counsel regarding the consequences of being
named or not being named as a selling securityholder in the Shelf Registration
Statement and related Prospectus.

     The term "Registrable Securities" is defined in the Exchange and
Registration Rights Agreement.
