<PAGE>   5
                                                                               5

                           Holder Questionnaire are registered under the Shelf
                           Registration Statement and have been disposed of in
                           accordance with the Shelf Registration Statement.


                 (b) No Holder of Transfer Restricted Securities may include any
of its Transfer Restricted Securities in the Shelf Registration Statement
pursuant to this Agreement unless such Holder furnishes to the Company in
writing, prior to or on the 20th Business Day after a request therefor (the
"QUESTIONNAIRE DEADLINE"), such information as the Company may reasonably
request for use in connection with the Shelf Registration Statement or
Prospectus or preliminary Prospectus included therein and in any application to
be filed with or under state securities laws (the form of which request is
attached as an Exhibit to the Supplemental Indenture and is referred to herein
as the "HOLDER QUESTIONNAIRE"). In connection with all such requests for
information from Holders of Transfer Restricted Securities, the Company shall
notify such Holders of the requirements set forth in the preceding sentence.
Holders that do not complete the Holder Questionnaire and timely deliver it to
the Company shall not be named as selling securityholders in the Prospectus or
preliminary Prospectus included in the Shelf Registration Statement and
therefore shall not be permitted to sell any Transfer Restricted Securities
pursuant to the Shelf Registration Statement. No Holder of Transfer Restricted
Securities shall be entitled to Liquidated Damages pursuant to Section 3 hereof
unless such Holder shall have provided all such reasonably requested information
prior to or on the Questionnaire Deadline. Each Holder as to which the Shelf
Registration Statement is being effected agrees to furnish promptly to the
Company all information required to be disclosed in order to make information
previously furnished to the Company by such Holder not materially misleading.
Each Holder who intends to be named as a selling Holder in the Shelf
Registration Statement shall promptly furnish to the Company in writing such
other information as the Company may from time to time reasonably request in
writing.

                 3. Liquidated Damages.

                 (a) If:

                           (i) the Shelf Registration Statement is not filed
                 with the Commission prior to or on the Shelf Filing Deadline;

                           (ii) the Shelf Registration Statement has not been
                 declared effective by the Commission prior to or on the
                 Effectiveness Target Date;

                           (iii) except as provided in Section 4(b)(i) hereof,
                 the Shelf Registration Statement is filed and declared
                 effective but, during the Effectiveness Period, shall
                 thereafter cease to be effective or fail to be usable for its
                 intended purpose without being succeeded within five Business
                 Days by a post-effective amendment to the Shelf Registration
                 Statement or a report filed with the Commission pursuant to
                 Section 13(a), 13(c), 14 or 15(d) of the Exchange Act that
                 cures such failure and, in the case of a post-effective
                 amendment, is itself immediately declared effective; or
<PAGE>   6
                                                                               6

                           (iv) (A) prior to or on the 45th or 75th day, as the
                 case may be, of any Suspension Period, such suspension has not
                 been terminated or (B) Suspension Periods exceed an aggregate
                 of 90 days in any 360 day period,

(each such event referred to in foregoing clauses (i) through (iv), a
"REGISTRATION DEFAULT"), the Company hereby agrees to pay liquidated damages
("LIQUIDATED DAMAGES") with respect to the Transfer Restricted Securities from
and including the day following the Registration Default to but excluding the
day on which the Registration Default has been cured, accruing at a rate:

                           (A) in respect of the Securities, to each holder of
                 Securities, (x) with respect to the first 90-day period during
                 which a Registration Default shall have occurred and be
                 continuing, equal to 0.25% per annum of the principal amount of
                 the Securities, and (y) with respect to the period commencing
                 on the 91st day following the day the Registration Default
                 shall have occurred and be continuing, equal to 0.50% per annum
                 of the principal amount of the Securities; provided that in no
                 event shall Liquidated Damages accrue at a rate per year
                 exceeding 0.50% of the principal amount of the Securities; and

                           (B) in respect of any shares of Common Stock, to each
                 holder of shares of Common Stock issued upon conversion of
                 Securities, (x) with respect to the first 90-day period in
                 which a Registration Default shall have occurred and be
                 continuing, equal to 0.25% per annum of the principal amount of
                 the converted Securities, and (y) with respect to the period
                 commencing the 91st day following the day the Registration
                 Default shall have occurred and be continuing, equal to 0.50%
                 per annum of the principal amount of the converted Securities;
                 provided that in no event shall Liquidated Damages accrue at a
                 rate per year exceeding 0.50% of the principal amount of the
                 converted Securities.

                 (b) All accrued Liquidated Damages shall be paid in arrears to
Record Holders by the Company on each Damages Payment Date by wire transfer of
immediately available funds or by federal funds check. Upon the cure of all
Registration Defaults relating to any particular Security or share of Common
Stock, the accrual of Liquidated Damages with respect to such Security or share
of Common Stock will cease.

                 All obligations of the Company set forth in this Section 3 that
are outstanding with respect to any Transfer Restricted Security at the time
such security ceases to be a Transfer Restricted Security shall survive until
such time as all such obligations with respect to such Transfer Restricted
Security shall have been satisfied in full.

                 The Liquidated Damages set forth above shall be the exclusive
monetary remedy available to the Holders of Transfer Restricted Securities for
such Registration Default.

                 4.        Registration Procedures.

                 (a) In connection with the Shelf Registration Statement, the
Company shall comply with all the provisions of Section 4(b) hereof and shall
use its reasonable commercial 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, and pursuant thereto, shall
as expeditiously as possible prepare and file with the Commission a Shelf
Registration Statement relating to the registration on any appropriate form
under the Securities Act.

                 (b) In connection with the Shelf Registration Statement and any
Prospectus required by this Agreement to permit the sale or resale of Transfer
Restricted Securities, the Company shall:

                           (i) Subject to any notice by the Company in
                 accordance with this Section 4(b) of the existence of any fact
                 or event of the kind described in Section 4(b)(iii)(D), use its
                 reasonable commercial efforts to keep the Shelf Registration
                 Statement continuously effective during the Effectiveness
                 Period; upon the occurrence of any event that would cause the
                 Shelf Registration Statement or the Prospectus contained
                 therein (A) to contain a material misstatement or omission or
                 (B) not be effective and usable for resale of Transfer
                 Restricted Securities during the Effectiveness Period, the
                 Company shall file promptly an appropriate amendment to the
                 Shelf Registration Statement or a report filed with the
                 Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the
                 Exchange Act, in the case of clause (A), correcting any such
                 misstatement or omission, and, in the case of either clause (A)
                 or (B), use its reasonable commercial efforts to cause such
                 amendment to be declared effective and the Shelf Registration
                 Statement and the related Prospectus to become usable for their
                 intended purposes as soon as practicable thereafter.
                 Notwithstanding the foregoing, the Company may suspend the
                 effectiveness of the Shelf Registration Statement by written
                 notice to the Holders for a period not to exceed an aggregate
                 of 45 days in any 90-day period (each such period, a
                 "SUSPENSION PERIOD") if:

                                    (x) an event occurs and is continuing as a
                           result of which the Shelf Registration Statement
                           would, in the Company's reasonable judgment, contain
                           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; and

                                    (y) the Company reasonably determines that
                           the disclosure of such event at such time would have
                           a material adverse effect on the business of the
                           Company and its subsidiaries taken as a whole;

                 provided that, in the event the disclosure relates to a
                 previously undisclosed proposed or pending material business
                 transaction, the disclosure of which would impede the Company's
                 ability to consummate such transaction, the Company may extend
                 a Suspension Period from 45 days to 75 days; provided, however,
                 that Suspension Periods shall not exceed an aggregate of 90
                 days in any 360-day period.

                           (ii) Prepare and file with the Commission such
                 amendments and post-effective amendments to the Shelf
                 Registration Statement as may be necessary to keep the Shelf
                 Registration Statement effective during the Effectiveness
                 Period; cause the Prospectus to be supplemented by any required
                 Prospectus supplement, and as so supplemented to be filed
                 pursuant to Rule 424 under the Securities Act, and to comply
                 fully with the applicable provisions of Rules 424 and 430A
                 under the Securities Act in a timely manner; and comply with
                 the provisions of the Securities Act with respect to the
                 disposition of all securities covered by the Shelf Registration
                 Statement during the applicable period in accordance with the
                 intended method or methods of distribution by the sellers
                 thereof set forth in the Shelf Registration Statement or
                 supplement to the Prospectus; provided that, in no event will
                 such method(s) of distribution take the form of an Underwritten
                 Offering without the prior agreement of the Company, which
                 agreement will not be unreasonably withheld.

                           (iii) Advise the underwriter(s), if any, and selling
                 Holders promptly (but in any event within five Business Days)
                 and, if requested by such Persons, to confirm such advice in
                 writing, except as provided in clause (D) below:

                                    (A) when the Prospectus 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 Securities 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, or

                                    (D) of the existence of any fact or the
                           happening of any event, during the Effectiveness
                           Period, that makes any statement of a material fact
                           made in the Shelf Registration Statement, the
                           Prospectus, any amendment or supplement thereto, or
                           any document incorporated by reference therein
                           untrue, or that requires the making of any additions
                           to or changes in the Shelf Registration Statement or
                           the Prospectus in order to make the statements
                           therein not misleading; provided that such notice
                           need only be provided to underwriters, if any, with
                           respect to an Underwritten Offering of which the
                           Issuer has notice and to selling Holders who have
                           given a Sale Notice as set forth in Section 4(d)
                           hereof who are then entitled to sell Transfer
                           Restricted Securities under the Shelf Registration
                           Statement pursuant to Section 4(d).

                 If at any time the Commission shall issue any stop order
                 suspending the effectiveness of the Shelf Registration
                 Statement, or any state securities commission or other
                 regulatory authority shall issue an order suspending the
                 qualification or exemption from qualification of the Transfer
                 Restricted Securities under state securities or Blue Sky laws,
                 the Company shall use its reasonable commercial efforts to
                 obtain the withdrawal or lifting of such order at the earliest
                 possible time and will provide to the Initial Purchaser and
                 each Holder who is named in the Shelf Registration Statement
                 prompt notice of the withdrawal of any such order.

                           (iv) Furnish to one counsel for the selling Holders
                 and each of the underwriter(s), if any, before filing with the
                 Commission, a copy of the Shelf Registration Statement and
                 copies of any Prospectus included therein or any amendments or
                 supplements to the Shelf Registration Statement or Prospectus
                 (other than documents incorporated by reference after the
                 initial filing of the Shelf Registration Statement), which
                 documents will be subject to the review of such holders and
                 underwriter(s), if any, for a period of at least five Business
                 Days (in the case of the Shelf Registration Statement) and two
                 Business Days (in the case of any amendment or supplement
                 thereto), and the Company will not file the Shelf Registration
                 Statement or Prospectus or any amendment or supplement to the
                 Shelf Registration Statement or Prospectus (other than
                 documents incorporated by reference) to which a selling Holder
                 of Transfer Restricted Securities covered by the Shelf
                 Registration Statement or the underwriter(s), if any, shall
                 reasonably object prior to the filing thereof. A selling Holder
                 or underwriter, if any, shall be deemed to have reasonably
                 objected to such filing if the Shelf Registration Statement,
                 amendment, Prospectus or supplement, as applicable, as proposed
                 to be filed, contains a material misstatement or omission.

                           (v) Make available at reasonable times for inspection
                 by one or more representatives of the selling Holders,
                 designated in writing by a Majority of Holders whose Transfer
                 Restricted Securities are included in the Shelf Registration
                 Statement, any underwriter participating in any distribution
                 pursuant to the Shelf Registration Statement, and any attorney
                 or accountant retained by such selling Holders or any of the
                 underwriter(s), all financial and other records, pertinent
                 corporate documents and properties of the Company as shall be
                 reasonably necessary to enable them to conduct a reasonable
                 investigation within the meaning of Section 11 of the
                 Securities Act, and cause the Company's officers, directors,
                 managers and employees to supply all information reasonably
                 requested by any such representative or representatives of the
                 selling Holders, underwriter, attorney or accountant in
                 connection therewith; provided, however, that the foregoing
                 inspection and information gathering shall be coordinated on
                 behalf of the selling Holders and any such underwriters by one
                 firm of counsel, which firm shall be Simpson Thacher & Bartlett
                 until another firm shall be designated in writing to the
                 Company by a Majority of Holders whose Transfer Restricted
                 Securities are included in the Shelf Registration Statement;
                 and provided further, that any information that is designated
                 in writing by the Company, in good faith, as confidential at
                 the time of delivery of such information shall be kept
                 confidential by the Holders or any such underwriters, attorney,
                 accountant or agent, unless such disclosure is made in
                 connection with a court proceeding or required by law, or
<PAGE>   10
                                                                              10

                 such information becomes available to the public generally or
                 through a third party without an accompanying obligation of
                 confidentiality.

                           (vi) If requested by any selling Holders or the
                 underwriter(s), if any, promptly incorporate in the Shelf
                 Registration Statement or Prospectus, pursuant to a supplement
                 or post-effective amendment if necessary, such information as
                 such selling Holders and underwriter(s), if any, may reasonably
                 request to have included therein, including, without limitation
                 (1) information relating to the "PLAN OF DISTRIBUTION" of the
                 Transfer Restricted Securities, (2) information with respect to
                 the principal amount of Securities or number of shares of
                 Common Stock being sold to such underwriter(s), (3) the
                 purchase price being paid therefor and (4) any other terms of
                 the offering of the Transfer Restricted Securities to be sold
                 in such offering and make all required filings of such
                 Prospectus supplement or post-effective amendment as soon as
                 reasonably practicable after the Company is notified of the
                 matters to be incorporated in such Prospectus supplement or
                 post-effective amendment necessary for Holders to be named as
                 selling Holders in the Prospectus and to allow such Holders to
                 deliver the Prospectus in connection with a sale of their
                 Transfer Restricted Securities, subject to Section 4(b)(i).

                           (vii) Furnish to each selling Holder and each of the
                 underwriter(s), if any, upon their request, without charge, at
                 least one copy of the Shelf Registration Statement, as first
                 filed with the Commission, and of each amendment thereto (and
                 any documents incorporated by reference therein or exhibits
                 thereto (or exhibits incorporated in such exhibits by
                 reference) as such Person may request).

                           (viii) Deliver to each selling Holder and each of the
                 underwriter(s), if any, without charge, as many copies of the
                 Prospectus (including each preliminary prospectus) and any
                 amendment or supplement thereto as such Persons reasonably may
                 request; subject to any notice by the Company in accordance
                 with this Section 4(b) of the existence of any fact or event of
                 the kind described in Section 4(b)(iii) (D), the Company hereby
                 consents to the use of the Prospectus and any amendment or
                 supplement thereto by each of the selling Holders and each of
                 the underwriter(s), if any, in connection with the offering and
                 the sale of the Transfer Restricted Securities covered by the

                           substance and scope as they may reasonably request
                           and as are customarily made by issuers to
                           underwriters in primary underwritten offerings for
                           selling security holders, upon the date of closing of
                           any sale of Transfer Restricted Securities in an

                                    professional standards, in the customary

                                    customarily covered in comfort letters to
                                    underwriters in connection with underwritten

                                    (B) set forth in full in the underwriting
                           agreement, if any, indemnification provisions and
                           procedures which provide rights no less protective
                           than those set forth in Section 7 of the Purchase
                           Agreement with respect to all parties to be
                           indemnified; and

                                    (C) deliver such other documents and
                           certificates as may be reasonably requested by such
                           parties to evidence compliance with clause (A) above
                           and with any customary conditions contained in the
                           underwriting agreement or other agreement entered
                           into by the selling Holders pursuant to this clause
                           (ix).

                           (x) Before any public offering of Transfer Restricted
                 Securities, cooperate with the selling Holders, the
                 underwriter(s), if any, and their respective counsel in
                 connection with the registration and qualification of the
                 Transfer Restricted Securities under the securities or Blue Sky
                 laws of such jurisdictions in the United States as the selling
                 Holders or underwriter(s), if any, may reasonably request 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 (A) to register or qualify as a foreign corporation or
                 a dealer of securities where it is not now so qualified or to
                 take any action that would subject it to the service of process
                 in any jurisdiction where it is not now so subject or (B) to
                 subject themselves to taxation in any such jurisdiction if they
                 are not now so subject.

                           (xi) Cooperate with the selling Holders and the
                 underwriter(s), if any, to facilitate the timely preparation
                 and delivery of certificates representing Transfer Restricted
                 Securities to be sold and not bearing any restrictive legends
                 (unless required by applicable securities laws); and enable
                 such Transfer Restricted Securities to be in such denominations
                 and registered in such names as the Holders or the
                 underwriter(s), if any, may request at least two Business Days
                 before any sale of Transfer Restricted Securities made by such
                 underwriter(s).

                           (xii) Subject to Section 4(b)(i) hereof, if any fact
                 or event contemplated by Section 4(b)(iii)(D) hereof shall

                 commercial efforts to prepare a supplement or post-effective
                 amendment 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 required to be
                 stated therein or necessary to make the statements therein, in
                 light of the circumstances in which they are made, not
                 misleading.

                           (xiii) Provide CUSIP numbers for all Transfer
                 Restricted Securities not later than the effective date of the
                 Shelf Registration Statement and provide the Trustee under the
                 Indenture with certificates for the Securities that are in a
                 form eligible for deposit with The Depository Trust Company.

                           (xiv) Cooperate and assist in any filings required to
                 be made with the NASD and in the performance of any due
                 diligence investigation by any underwriter that is required to
                 be retained in accordance with the rules and regulations of the
                 NASD.

                           (xv) Otherwise use its reasonable commercial efforts
                 to comply with all applicable rules and regulations of the
                 Commission and all reporting requirements under the rules and
                 regulations of the Exchange Act.

                           (xvi) Cause the Indenture to be qualified under the
                 TIA not later than the effective date of the Shelf Registration
                 Statement required by this Agreement, and, in connection
                 therewith, cooperate with the Trustee and the holders of
                 Securities to effect such changes to the Indenture as may be
                 required for such Indenture to be so qualified in accordance
                 with the terms of the TIA; and execute and use its reasonable
                 commercial efforts to cause the Trustee thereunder to execute
                 all documents that may be required to effect such changes and
                 all other forms and documents required to be filed with the
                 Commission to enable such Indenture to be so qualified in a
                 timely manner.

                           (xvii) Cause all Conversion Shares covered by the
                 Shelf Registration Statement to be listed or quoted, as the
                 case may be, on each securities exchange or automated quotation
                 system on which similar securities issued by the Company are
                 then listed or quoted.

                           (xviii) Provide to each Holder upon written request
                 each document filed with the Commission pursuant to the
                 requirements of Section 13 and Section 15 of the Exchange Act
                 after the effective date of the Shelf Registration Statement.

                 (c) Each Holder agrees by acquisition of a Transfer Restricted
Security that, upon receipt of any notice (a "SUSPENSION NOTICE") from the
Company of the existence of any fact of the kind described in Section
4(b)(iii)(D) hereof, such Holder will, and will use its reasonable best efforts
to cause any underwriter(s) in an Underwritten Offering to, forthwith
discontinue disposition of Transfer Restricted Securities pursuant to the Shelf
Registration Statement until:
<PAGE>   13
                                                                              13

                           (i) such Holder has received copies of the
                 supplemented or amended Prospectus contemplated by Section
                 4(b)(xiii) hereof; or

                           (ii) 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.

If so directed by the Company, each Holder will 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 such notice of suspension.

                 (d) Upon the effectiveness of the Shelf Registration Statement,
each Holder shall notify the Company at least three Business Days prior thereto
of any intended distribution of Transfer Restricted Securities pursuant to the
Shelf Registration Statement (a "SALE NOTICE"), which notice shall be effective
for five Business Days. Each Holder of Transfer Restricted Securities, by
accepting the same, agrees to hold any communication by the Company in response
to a Sale Notice in confidence. Upon receipt of a Sale Notice, the Company shall
inform each Holder in writing of the existence of a Suspension Period or
otherwise, of the kind of event described in Section 4(b)(iii)(D).

                 5. Registration Expenses.

                 (a) All expenses incident to the Company's performance of or
compliance with this Agreement shall be borne by the Company regardless of
whether a Shelf Registration Statement becomes effective, including, without
limitation:

                           (i) all registration and filing fees and expenses
                 (including filings made by any Initial Purchaser or Holders
                 with the NASD);

                           (ii) all fees and expenses of compliance with federal
                 securities and state Blue Sky or securities laws;

                           (iii) all expenses of printing (including printing of
                 Prospectuses and certificates for the Common Stock to be issued
                 upon conversion of the Securities) and the Company's expenses
                 for messenger and delivery services and telephone;

                           (iv) all fees and disbursements of counsel to the
                 Company and, subject to Section 5(b) below, the Holders of
                 Transfer Restricted Securities;

                           (v) all application and filing fees in connection
                 with listing (or authorizing for quotation) the Common Stock on
                 a national securities exchange or automated quotation system
                 pursuant to the requirements hereof; and

                           (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).
<PAGE>   14
                                                                              14

                 The Company shall bear its internal expenses (including,
without limitation, all salaries and expenses of their officers and employees
performing legal, accounting or other duties), the expenses of any annual audit
and the fees and expenses of any Person, including special experts, retained by
the Company.

                 (b) In connection with the Shelf Registration Statement
required by this Agreement, including any amendment or supplement thereto, and
any other documents delivered to any Holders, the Company shall reimburse the
Initial Purchaser and the Holders of Transfer Restricted Securities being
registered pursuant to the Shelf Registration Statement, as applicable, for the
reasonable fees and disbursements of not more than one counsel, which shall be
Simpson Thacher & Bartlett, or such other counsel as may be chosen by a Majority
of Holders for whose benefit the Shelf Registration Statement is being prepared.

                 6. Indemnification and Contribution.

                 (a) The Company shall indemnify and hold harmless each Holder,
such Holder's officers and employees and each person, if any, who controls such
Holder within the meaning of the Securities Act (each, an "INDEMNIFIED HOLDER"),
from and against any loss, claim, damage or liability, joint or several, or any
action in respect thereof (including, but not limited to, any loss, claim,
damage, liability or action relating to resales of the Transfer Restricted
Securities), to which such Indemnified Holder may become subject, insofar as any
such loss, claim, damage, liability or action arises out of, or is based upon:

                 (i) any untrue statement or alleged untrue statement of a
        material fact contained in the Shelf Registration Statement or
        Prospectus or any amendment or supplement thereto; or

                 (ii) the omission or alleged omission to state therein any
        material fact required to be stated therein or necessary to make the
        statements therein, in the light of the circumstances under which they
        were made, not misleading,

and shall reimburse each Indemnified Holder promptly upon demand for any legal
or other expenses reasonably incurred by such Indemnified Holder in connection
with investigating or defending or preparing to defend against any such loss,
claim, damage, liability or action as such expenses are incurred; provided,
however, that the Company shall not be liable in any such case to the extent
that any such loss, claim, damage, liability or action arises out of, or is
based upon, any untrue statement or alleged untrue statement or omission or
alleged omission made in the Shelf Registration Statement or Prospectus or
amendment or supplement thereto in reliance upon and in conformity with written
information furnished to the Company by or on behalf of any Holder (or its
related Indemnified Holder) specifically for use therein. The foregoing
indemnity agreement is in addition to any liability which the Company may
otherwise have to any Indemnified Holder.

                 (b) Each Holder, severally and not jointly, shall indemnify and
hold harmless the Company, its officers and employees and each person, if any,
who controls the Company within the meaning of the Securities Act, from and
against any loss, claim, damage or liability, joint or several, or any action in
respect thereof, to which the Company or any such officer, employee or
controlling person may become subject, insofar as any such loss, claim, damage
or liability or action arises out of, or is based upon:
<PAGE>   15
                                                                              15

                 (i) any untrue statement or alleged untrue statement of any
        material fact contained in the Shelf Registration Statement or
        Prospectus or any amendment or supplement thereto; or

                 (ii) the omission or the alleged omission to state therein any
        material fact required to be stated therein or necessary to make the
        statements therein, in light of the circumstances under which they were
        made, not misleading,

but in each case 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 or on behalf of
such Holder (or its related Indemnified Holder) specifically for use therein,
and shall reimburse the Company and any such officer, employee or controlling
person promptly upon demand for any legal or other expenses reasonably incurred
by the Company or any such officer, employee or controlling person in connection
with investigating or defending or preparing to defend against any such loss,
claim, damage, liability or action as such expenses are incurred. The foregoing
indemnity agreement is in addition to any liability which any Holder may
otherwise have to the Company and any such officer, employee or controlling
person.

                 (c) Promptly after receipt by an indemnified party under this
Section 6 of notice of any claim or the commencement of any action, the
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under this Section 6, notify the indemnifying party in
writing of the claim or the commencement of that action; provided, however, that
the failure to notify the indemnifying party shall not relieve it from any
liability which it may have under this Section 6 except to the extent it has
been materially prejudiced by such failure and, provided, further, that the
failure to notify the indemnifying party shall not relieve it from any liability
which it may have to an indemnified party otherwise than under this Section 6.
If any such claim or action shall be brought against an indemnified party, and
it shall notify the indemnifying party thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it wishes, jointly with
any other similarly notified indemnifying party, to assume the defense thereof
with counsel satisfactory to the indemnified party. After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 6 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
the Holders shall have the right to employ one separate firm to represent
jointly the Holders and their officers, employees and controlling persons who
may be subject to liability arising out of any claim in respect of which
indemnity may be sought by the Holders against the Company under this Section 6
if the Holders seeking indemnification shall have been advised by legal counsel
that there may be one or more legal defenses available to such Holders and their
officers, employees and controlling persons that are different from or
additional to those available to the Issuer, and in that event the fees and
expenses of such separate counsel shall be paid by the Company. No indemnifying
party shall:

                 (i) without the prior written consent of the indemnified
        parties (which consent shall not be unreasonably withheld) settle or
        compromise or consent to the entry of any judgment with respect to any
        pending or threatened claim, action, suit or proceeding in respect of
        which indemnification or contribution may be sought hereunder (whether
        or not
<PAGE>   16
                                                                              16

        the indemnified parties are actual or potential parties to such claim or
        action) unless such settlement, compromise or consent includes an
        unconditional release of each indemnified party from all liability
        arising out of such claim, action, suit or proceeding, or

                 (ii) be liable for any settlement of any such action effected
        without its written consent (which consent shall not be unreasonably
        withheld), but if settled with its written consent or if there be a
        final judgment for the plaintiff in any such action, the indemnifying
        party agrees to indemnify and hold harmless any indemnified party from
        and against any loss of liability by reason of such settlement or
        judgment.

                 (d) If the indemnification provided for in this Section 6 shall
for any reason be unavailable or insufficient to hold harmless an indemnified
party under Section 6(a) or 6(b) in respect of any loss, claim, damage or
liability (or action in respect thereof) referred to therein, each indemnifying
party shall, in lieu of indemnifying such indemnified party, contribute to the
amount paid or payable by such indemnified party as a result of such loss,
claim, damage or liability (or action in respect thereof):

                  (i) in such proportion as is appropriate to reflect the
        relative benefits received by the Company from the offering and sale of
        the Transfer Restricted Securities on the one hand and a Holder with
        respect to the sale by such Holder of the Transfer Restricted Securities
        on the other, or

                 (ii) if the allocation provided by clause (6)(d)(i) is not
        permitted by applicable law, in such proportion as is appropriate to
        reflect not only the relative benefits referred to in clause 6(d)(i) but
        also the relative fault of the Company on the one hand and the Holders
        on the other in connection with the statements or omissions or alleged
        statements or alleged omissions that resulted in such loss, claim,
        damage or liability (or action in respect thereof), as well as any other
        relevant equitable considerations.

The relative benefits received by the Company on the one hand and a Holder on
the other with respect to such offering and such sale shall be deemed to be in
the same proportion as the total net proceeds from the offering of the
Securities purchased under the Purchase Agreement (before deducting expenses)
received by the Company, on the one hand, bear to the total net gain received by
such Holder with respect to its sale of Transfer Restricted Securities on the
other. The relative fault of the parties shall be determined by reference to
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 the Holders on the other, the intent
of the parties and their relative knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and
each Holder agree that it would not be just and equitable if the amount of
contribution pursuant to this Section 6(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the first sentence of this paragraph
(d). The amount paid or payable by an indemnified party as a result of the loss,
claim, damage or liability, or action in respect thereof, referred to above in
this Section 6 shall be deemed to include, for purposes of this Section 6, any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending or preparing to defend any such
action or claim. Notwithstanding the provisions of this Section 6, no Holder
shall be required to contribute any amount in excess of the amount by which the
total price at which the Transfer Restricted Securities purchased by it were
resold exceeds the amount of any damages which such
<PAGE>   17
                                                                              17

Holder has otherwise been required to pay by reason of any 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' obligations to contribute as provided
in this Section 6(d) are several and not joint.

                 7. Rule 144A. In the event the Company is not subject to
Section 13 or 15(d) of the Exchange Act, the Company hereby agrees with each
Holder, for so long as any Transfer Restricted Securities remain outstanding, to
make available to any Holder or beneficial owner of Transfer Restricted
Securities in connection with any sale thereof and any prospective purchaser of
such Transfer Restricted Securities from such Holder or beneficial owner, the
information required by Rule 144A(d)(4) under the Securities Act in order to
permit resales of such Transfer Restricted Securities pursuant to Rule 144A.

                 8. Participation in Underwritten Registrations. No Holder may
participate in any Underwritten Registration hereunder unless such Holder:

                 (i) agrees to sell such Holder's Transfer Restricted 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 reasonable questionnaires,
        powers of attorney, indemnities, underwriting agreements, lock-up
        letters and other documents required under the terms of such
        underwriting arrangements.

                 9. Selection of Underwriters. The Holders of Transfer
Restricted Securities covered by the Shelf Registration Statement who desire to
do so may sell such Transfer Restricted Securities in an Underwritten Offering
if approved by the Company as provided in Section 4(b)(ii). In any such
Underwritten Offering, the investment banker or investment bankers and manager
or managers that will administer the offering will be selected by a Majority of
Holders whose Transfer Restricted Securities are included in such offering;
provided, that such investment bankers and managers must be reasonably
satisfactory to the Company.

                 10. Miscellaneous.

                 (a) Remedies. The Company acknowledges and agrees that any
failure by the Company to comply with its obligations under Section 2 hereof may
result in material irreparable injury to the Initial Purchaser 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 Initial Purchaser or any Holder may obtain such relief as may be
required to specifically enforce the Company's obligations under Section 2
hereof. The Company further agrees to waive the defense in any action for
specific performance that a remedy at law would be adequate.

                 (b) Actions Affecting Transfer Restricted Securities. The
Company shall not, directly or indirectly, take any action with respect to the
Transfer Restricted Securities as a class that would adversely affect the
ability of the Holders of Transfer Restricted Securities to include such
Transfer Restricted Securities in a registration undertaken pursuant to this
Agreement.
<PAGE>   18
                                                                              18

                 (c) 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 breaches or results in a default under or violation of
the provisions hereof. In addition, 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 its securities in the Shelf
Registration Statement provided for in this Agreement other than the Transfer
Restricted Securities. 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 which rights conflict with the
provisions hereof.

                 (d) Amendments and Waivers. 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 the Company has obtained the written
consent of a Majority of Holders.

                 (e) Notices. All notices and other communications provided for
or permitted hereunder shall be made in writing by hand-delivery, first-class

                 (f) 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 need for an express
assignment, subsequent Holders of Transfer Restricted Securities; provided,
however, that (i) this Agreement shall not inure to the benefit of or be binding
upon a successor or assign of a Holder unless and to the extent such successor
or assign acquired Transfer Restricted Securities from such Holder and (ii)
nothing contained herein shall be deemed to permit any assignment, transfer or
other disposition of Transfer Restricted Securities in violation of the terms of
the Purchase Agreement or the Indenture. 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.
 .
                 (g) 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.

                 (h) Securities Held by the Company or Their Affiliates.
Whenever the consent or approval of Holders of a specified percentage of
Transfer Restricted Securities is required hereunder, Transfer Restricted
Securities held by the Company or its "affiliates" (as such term is defined in
Rule 405 under the Securities Act) shall not be counted in determining whether
such consent or approval was given by the Holders of such required percentage.

                 (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 LAW OF THE STATE OF NEW YORK.

                 (k) Severability. If 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 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 by the Company with
respect to the Transfer Restricted Securities. This Agreement supersedes all
prior agreements and understandings between the parties with respect to such
subject matter.
