               (a) The Company shall prepare and file or cause to be prepared
and filed with the SEC no later than a date which is ninety (90) days after the
Issue Date (the "Filing Deadline Date") a Registration Statement for an offering
to be made on a delayed or continuous basis pursuant to Rule 415 of the
Securities Act (a "Shelf Registration Statement") registering the resale from
time to time by Holders thereof of all of the Registrable Securities (the
"Initial Shelf Registration Statement"). The Initial Shelf Registration
Statement shall be on Form S-3 or another appropriate form permitting
registration of such Registrable Securities for resale by such Holders in
accordance with the methods of distribution reasonably elected by the Holders
and set forth in the Initial Shelf Registration Statement; provided, that in no
event will such method(s) of distribution take the form of an underwritten
offering of the Registrable Securities without the prior agreement of the
Company. The Company shall use reasonable efforts to cause the Initial Shelf
Registration Statement to be declared effective under the Securities Act by the
date (the "Effectiveness Deadline Date") that is two hundred and ten (210) days
after the Issue Date, and to keep the Initial Shelf Registration Statement (or
any Subsequent Shelf Registration Statement) continuously effective under the
Securities Act until the expiration of the Effectiveness Period. At the time the
Initial Shelf Registration Statement is declared effective, each Holder that
became a Notice Holder on or prior to the date 10 Business Days


                                       4
<PAGE>   5
prior to such time of effectiveness shall be named as a selling security holder
in the Initial Shelf Registration Statement and the related Prospectus in such a
manner as to permit such Holder to deliver such Prospectus to purchasers of
Registrable Securities in accordance with applicable law (other than laws not
generally applicable to all such Holders). None of the Company's security
holders (other than the Holders of Registrable Securities) shall have the right
to include any of the Company's securities in the Shelf Registration Statement.

               (b) If the Initial Shelf Registration Statement or any Subsequent
Shelf Registration Statement ceases to be effective for any reason at any time
during the Effectiveness Period, the Company shall use reasonable efforts to
obtain the prompt withdrawal of any order suspending the effectiveness thereof,
and in any event shall within thirty (30) days of such cessation of
effectiveness amend the Shelf Registration Statement in a manner reasonably
expected by the Company to obtain the withdrawal of the order suspending the
effectiveness thereof, or file an additional Shelf Registration Statement
covering all of the securities that as of the date of such filing are
Registrable Securities (a "Subsequent Shelf Registration Statement"). If a
Subsequent Shelf Registration Statement is filed, the Company shall use
reasonable efforts to cause the Subsequent Shelf Registration Statement to
become effective as promptly as is reasonably practicable after such filing or,
if filed during a Deferral Period, after the expiration of such Deferral Period,
and to keep such Registration Statement (or subsequent Shelf Registration
Statement) continuously effective until the end of the Effectiveness Period.

               (c) The Company shall supplement and amend the Shelf Registration
Statement if required by the rules, regulations or instructions applicable to
the registration form used by the Company for such Shelf Registration Statement,
if required by the Securities Act or, to the extent to which the Company does
not reasonably object, as reasonably requested by the Initial Purchaser or by
the Trustee on behalf of the registered Holders.

               (d) Each Holder of Registrable Securities agrees that if such
Holder wishes to sell Registrable Securities pursuant to a Shelf Registration
Statement and related Prospectus, it will do so only in accordance with this
Section 2(d) and Section 3(i). Each Holder of Registrable Securities wishing to
sell Registrable Securities pursuant to a Shelf Registration Statement and
related Prospectus agrees to deliver a Notice and Questionnaire to the Company
at least five (5) Business Days prior to any intended distribution of
Registrable Securities under the Shelf Registration Statement. From and after
the date the Initial Shelf Registration Statement is declared effective, the
Company shall, as promptly as is reasonably practicable after the date a Notice
and Questionnaire is delivered, (i) if required by applicable law, file with the
SEC a post-effective amendment to the Shelf Registration Statement or prepare
and, if required by applicable law, file a supplement to the related Prospectus
or a supplement or amendment to any document incorporated therein by reference
or file any other document required by the SEC so that the Holder delivering
such Notice and Questionnaire is named as a selling security holder in the Shelf
Registration Statement and the related Prospectus in such a manner as to permit
such Holder to deliver such Prospectus to purchasers of the Registrable
Securities in accordance with applicable law (other than laws not generally
applicable to all Holders of Registrable Securities wishing to sell Registrable
Securities pursuant to the Shelf Registration Statement and related Prospectus)
and, if the


                                       5
<PAGE>   6
Company shall file a post-effective amendment to the Shelf Registration
Statement, use reasonable efforts to cause such post-effective amendment to be
declared effective under the Securities Act as promptly as is reasonably
practicable; (ii) provide such Holder copies of any documents filed pursuant to
Section 2(d)(i); and (iii) notify such Holder as promptly as is reasonably
practicable after the effectiveness under the Securities Act of any
post-effective amendment filed pursuant to Section 2(d)(i); provided, that if
such Notice and Questionnaire is delivered during a Deferral Period, the Company
shall so inform the Holder delivering such Notice and Questionnaire and shall
take the actions set forth in clauses (i), (ii) and (iii) above upon expiration
of the Deferral Period in accordance with Section 3(i), provided, further, that
if under applicable law the Company has more than one option as to the type or
manner of making any such filing, as set forth in an opinion of
nationally-recognized counsel experienced in such matters delivered by the
Holder to the Company, it will make the required filing or filings in the manner
or of a type that is reasonably expected to result in the earliest availability
of the Prospectus for effecting resales of Registrable Securities.
Notwithstanding anything contained herein to the contrary, the Company shall be
under no obligation to name any Holder that is not a Notice Holder as a selling
security holder in any Registration Statement or related Prospectus; provided,
however, that any Holder that becomes a Notice Holder pursuant to the provisions
of Section 2(d) of this Agreement (whether or not such Holder was a Notice
Holder at the time the Registration Statement was initially declared effective)
shall be named as a selling security holder in the Registration Statement or
related Prospectus subject to and in accordance with the requirements of this
Section 2(d).

               (e) The parties hereto agree that the Holders of Registrable
Securities will suffer damages, and that it would not be feasible to ascertain
the extent of such damages with precision, if (i) the Initial Shelf Registration
Statement has not been filed on or prior to the Filing Deadline Date, (ii) the
Initial Shelf Registration Statement has not been declared effective under the
Securities Act on or prior to the Effectiveness Deadline Date, or (iii) the
aggregate duration of Deferral Periods in any period exceeds the number of days
permitted in respect of such period pursuant to Section 3(i) hereof (each of the
events of a type described in any of the foregoing clauses (i) through (iii) are
individually referred to herein as an "Event," and the Filing Deadline Date in
the case of clause (i), the Effectiveness Deadline Date in the case of clause
(ii), and the date on which the aggregate duration of Deferral Periods in any
period exceeds the number of days permitted by Section 3(i) hereof in the case
of clause (iii), being referred to herein as an "Event Date"). Events shall be
deemed to continue until the "Event Termination Date," which shall be the
following dates with respect to the respective types of Events: the date the
Initial Shelf Registration Statement is filed in the case of an Event of the
type described in clause (i), the date the Initial Shelf Registration Statement
is declared effective under the Securities Act in the case of an Event of the
type described in clause (ii), termination of the Deferral Period that caused
the limit on the aggregate duration of Deferral Periods in a period set forth in
Section 3(i) to be exceeded in the case of the commencement of an Event of the
type described in clause (iii).

               Accordingly, commencing on (and including) any Event Date and
ending on (but excluding) the next date on which there are no Events that have
occurred and are continuing (a "Damages Accrual Period"), the Company agrees to
pay, as liquidated damages and not as a penalty, an amount (the "Liquidated
Damages Amount"), payable on the


                                       6
<PAGE>   7
Damages Payment Dates to Record Holders of then outstanding LYONs that are
Registrable Securities or of then outstanding shares of Underlying Common Stock
issued upon conversion of LYONs that are Registrable Securities, as the case may
be, accruing, for each portion of such Damages Accrual Period beginning on and
including a Damages Payment Date (or, in respect of the first time that the
Liquidation Damages Amount is to be paid to Holders on a Damages Payment Date as
a result of the occurrence of any particular Event, from the Event Date) and
ending on but excluding the first to occur of (A) the date of the end of the
Damages Accrual Period or (B) the next Damages Payment Date, at a rate per annum
equal to one-quarter of one percent (0.25%) for the first 90-day period from the
Event Date, and thereafter at a rate per annum equal to one-half of one percent
(0.5%) of the aggregate Applicable Principal Amount of such LYONs, the aggregate
Applicable Conversion Price of the shares of Underlying Common Stock and the
Restated Principal Amount of the Semi-annual Coupon Notes, as the case may be,
in each case determined as of the Business Day immediately preceding the next
Damages Payment Date; provided, that any Liquidated Damages Amount accrued with
respect to any LYON or portion thereof called for redemption on a redemption
date or converted into Underlying Common Stock on a conversion date or to
Semi-annual Coupon Notes prior to the Damages Payment Date, shall, in any such
event, be paid instead to the Holder who submitted such LYON or portion thereof
for redemption or conversion on the applicable redemption date or conversion
date, as the case may be, on such date (or promptly following the conversion
date, in the case of conversion). Notwithstanding the foregoing, no Liquidated
Damages Amounts shall accrue as to any Registrable Security from and after the
earlier of (x) the date such security is no longer a Registrable Security and
(y) expiration of the Effectiveness Period. The rate of accrual of the
Liquidated Damages Amount with respect to any period shall not exceed the rate
provided for in this paragraph notwithstanding the occurrence of multiple
concurrent Events. Following the cure of all Events requiring the payment by the
Company of Liquidated Damages Amounts to the Holders of Registrable Securities
pursuant to this Section, the accrual of Liquidated Damages Amounts will cease
(without in any way limiting the effect of any subsequent Event requiring the
payment of the Liquidated Damages Amount by the Company).

               The Trustee shall be entitled, on behalf of Holders of LYONs,
Underlying Common Stock or Semi-annual Coupon Notes, to seek any available
remedy for the enforcement of this Agreement, including for the payment of any
Liquidated Damages Amount. Notwithstanding the foregoing, the parties agree that
the sole monetary damages payable for a violation of the terms of this Agreement
with respect to which liquidated damages are expressly provided shall be such
liquidated damages. Nothing shall preclude a Notice Holder or Holder of
Registrable Securities from pursuing or obtaining specific performance or other
equitable relief with respect to this Agreement.

               All of the Company's obligations set forth in this Section 2(e)
that are outstanding with respect to any Registrable Security at the time such
security ceases to be a Registrable Security shall survive until such time as
all such obligations with respect to such security have been satisfied in full
(notwithstanding termination of this Agreement pursuant to Section 8(k)).


                                       7
<PAGE>   8
               The parties hereto agree that the liquidated damages provided for
in this Section 2(e) constitute a reasonable estimate of the damages that may be
incurred by Holders of Registrable Securities by reason of the failure of the
Shelf Registration Statement to be filed or declared effective or available for
effecting resales of Registrable Securities in accordance with the provisions
hereof.

               SECTION 3. Registration Procedures. In connection with the
registration obligations of the Company under Section 2 hereof, the Company
shall:

               (a) Before filing any Registration Statement or Prospectus or any
amendments or supplements (other than supplements that do nothing more
substantive than name one or more Notice Holders as selling security holders)
thereto with the SEC, furnish to the Initial Purchaser copies of all such
documents proposed to be filed and use reasonable efforts to reflect in each
such document when so filed with the SEC such comments as the Initial Purchaser
reasonably shall propose within two (2) Business Days of the delivery of such
copies to the Initial Purchaser.

               (b) Prepare and file with the SEC such amendments and
post-effective amendments to each Registration Statement as may be necessary to
keep such Registration Statement continuously effective for the applicable
period specified in Section 2(a); cause the related Prospectus to be
supplemented by any required Prospectus supplement, and as so supplemented to be
filed pursuant to Rule 424 (or any similar provisions then in force) under the
Securities Act; and use reasonable efforts to comply with the provisions of the
Securities Act applicable to it with respect to the disposition of all
securities covered by such Registration Statement during the Effectiveness
Period in accordance with the intended methods of disposition by the sellers
thereof set forth in such Registration Statement as so amended or such
Prospectus as so supplemented.

               (c) As promptly as reasonably practicable give notice to the
Notice Holders and the Initial Purchaser (i) when any Prospectus, Prospectus
supplement, Registration Statement or post-effective amendment to a Registration
Statement has been filed with the SEC and, with respect to a Registration
Statement or any post-effective amendment, when the same has been declared
effective (provided, however, that the Company shall not be required by this
clause (i) to notify (A) the Initial Purchaser of the filing of a Prospectus
supplement that does nothing more substantive than name one or more Notice
Holders as selling security holders or (B) any Notice Holder of the filing of a
Prospectus supplement that does nothing more substantive than name one or more
other Notice Holders as selling security holders), (ii) of any request,
following the effectiveness of the Initial Shelf Registration Statement under
the Securities Act, by the SEC or any other federal or state governmental
authority for amendments or supplements to any Registration Statement or related
Prospectus or for additional information, (iii) of the issuance by the SEC or
any other federal or state governmental authority of any stop order suspending
the effectiveness of any Registration Statement or the initiation or threatening
of any proceedings for that purpose, (iv) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purpose, (v) of the occurrence of (but not the nature of or details


                                       8
<PAGE>   9
concerning) a Material Event (provided, however, that no notice by the Company
shall be required pursuant to this clause (v) in the event that the Company
either promptly files a Prospectus supplement to update the Prospectus or a Form
8-K or other appropriate Exchange Act report that is incorporated by reference
into the Registration Statement, which, in either case, contains the requisite
information with respect to such Material Event that results in such
Registration Statement no longer containing any untrue statement of material
fact or omitting to state a material fact necessary to make the statements
contained therein not misleading) and (vi) of the determination by the Company
that a post-effective amendment to a Registration Statement will be filed with
the SEC, which notice may, at the discretion of the Company (or as required
pursuant to Section 3(i)), state that it constitutes a Deferral Notice, in which
event the provisions of Section 3(i) shall apply.

               (d) Use reasonable efforts to obtain the withdrawal of any order
suspending the effectiveness of a Registration Statement or the lifting of any
suspension of the qualification (or exemption from qualification) of any of the
Registrable Securities for sale in any jurisdiction in which they have been
qualified for sale, in either case at the earliest possible moment or, if any
such order or suspension is made effective during any Deferral Period, at the
earliest possible moment after the expiration of such Deferral Period.

               (e) If reasonably requested by the Initial Purchaser or any
Notice Holder, as promptly as reasonably practicable incorporate in a Prospectus
supplement or post-effective amendment to a Registration Statement such
information as the Initial Purchaser or such Notice Holder shall, on the basis
of a reasonable opinion of nationally-recognized counsel experienced in such
matters, determine to be required to be included therein by applicable law and
make any required filings of such Prospectus supplement or such post- effective
amendment; provided, that the Company shall not be required to take any actions
under this Section 3(e) that are not, in the reasonable opinion of counsel for
the Company, in compliance with applicable law.

               (f) As promptly as reasonably practicable furnish to each Notice
Holder and the Initial Purchaser, upon their request and without charge, at
least one (1) conformed copy of the Registration Statement and any amendment
thereto, including financial statements, but excluding schedules, all documents
incorporated or deemed to be incorporated therein by reference and all exhibits
(unless requested in writing to the Company by such Notice Holder or the Initial
Purchaser, as the case may be).

               (g) During the Effectiveness Period, deliver to each Notice
Holder in connection with any sale of Registrable Securities pursuant to a
Registration Statement, without charge, as many copies of the Prospectus or
Prospectuses relating to such Registrable Securities (including each preliminary
prospectus) and any amendment or supplement thereto as such Notice Holder may
reasonably request; and the Company hereby consents (except during such periods
that a Deferral Notice is outstanding and has not been revoked) to the use of
such Prospectus or each amendment or supplement thereto by each Notice Holder in
connection with any offering and sale of the Registrable Securities covered by
such Prospectus or any amendment or supplement thereto in the manner set forth
therein.

<PAGE>   10
               (h) Subject to Section 3(i), prior to any public offering of the
Registrable Securities pursuant to the Shelf Registration Statement, use
reasonable efforts to register or qualify or cooperate with the Notice Holders
in connection with the registration or qualification (or exemption from such
registration or qualification) of such Registrable Securities for offer and sale
under the securities or Blue Sky laws of such jurisdictions within the United
States as any Notice Holder reasonably requests in writing (which request may be
included in the Notice and Questionnaire), it being agreed that no such
registration or qualification will be made unless so requested; prior to any
public offering of the Registrable Securities pursuant to the Shelf Registration
Statement, use reasonable efforts to keep each such registration or
qualification (or exemption therefrom) effective during the Effectiveness Period
in connection with such Notice Holder's offer and sale of Registrable Securities
pursuant to such registration or qualification (or exemption therefrom) and do
any and all other acts or things necessary to enable the disposition in such
jurisdictions of such Registrable Securities in the manner set forth in the
relevant Registration Statement and the related Prospectus; provided, that the
Company will not be required to (i) qualify as a foreign corporation or as a
dealer in securities in any jurisdiction where it is not otherwise qualified or
(ii) take any action that would subject it to general service of process in
suits or to taxation in any such jurisdiction where it is not then so subject.

               (i) Upon (A) the issuance by the SEC of a stop order suspending
the effectiveness of the Shelf Registration Statement or the initiation of
proceedings with respect to the Shelf Registration Statement under Section 8(d)
or 8(e) of the Securities Act, (B) the occurrence of any event or the existence
of any fact (a "Material Event") as a result of which any Registration Statement
shall contain any 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 not misleading, or any Prospectus shall contain any 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 the light of the circumstances
under which they were made, not misleading (including, in any such case, as a
result of the non-availability of financial statements), or (C) the occurrence
or existence of any corporate development that, in the discretion of the
Company, makes it appropriate to suspend the availability of the Shelf
Registration Statement and the related Prospectus, (i) in the case of clause (B)
above, subject to the next sentence, as promptly as practicable prepare and file
a post-effective amendment to such Registration Statement or a supplement to the
related Prospectus or any document incorporated therein by reference or file any
other required document that would be incorporated by reference into such
Registration Statement and Prospectus so that such Registration Statement does
not contain any 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 not misleading, and such Prospectus does not contain any 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 the light of the
circumstances under which they were made, not misleading, as thereafter
delivered to the purchasers of the Registrable Securities being sold thereunder,
and, in the case of a post-effective amendment to a Registration Statement,
subject to the next sentence, use reasonable efforts to cause it to be declared
effective as promptly as is reasonably practicable, and (ii) give notice to the
Notice Holders that the availability of the Shelf Registration Statement is
suspended (a "Deferral Notice") and, upon receipt of any Deferral Notice, each
Notice Holder agrees not to sell any Registrable


                                       10
<PAGE>   11
Securities pursuant to the Registration Statement until such Notice Holder's
receipt of copies of the supplemented or amended Prospectus provided for in
clause (i) above, or until it is advised in writing by the Company that the
Prospectus may be used, and has received copies of any additional or
supplemental filings that are incorporated or deemed incorporated by reference
in such Prospectus. The Company will use reasonable efforts to ensure that the
use of the Prospectus may be resumed (x) in the case of clause (A) above, as
promptly as is practicable, (y) in the case of clause (B) above, as soon as, in
the sole judgment of the Company, public disclosure of such Material Event would
not be prejudicial to or contrary to the interests of the Company or, if
necessary to avoid unreasonable burden or expense, as soon as reasonably
practicable thereafter and (z) in the case of clause (C) above, as soon as, in
the discretion of the Company, such suspension is no longer appropriate. The
period during which the availability of the Registration Statement and any
Prospectus is suspended (the "Deferral Period") shall, without the Company
incurring any obligation to pay liquidated damages pursuant to Section 2(e), not
exceed forty-five (45) days in any three (3) month period or one hundred and
twenty (120) days in any twelve (12) month period.

               (j) If reasonably requested in writing in connection with a
disposition of Registrable Securities pursuant to a Registration Statement, make
reasonably available for inspection during normal business hours by a
representative for the Notice Holders of such Registrable Securities and any
broker-dealers, attorneys and accountants retained by such Notice Holders, all
relevant financial and other records, pertinent corporate documents and
properties of the Company and its subsidiaries, and cause the appropriate
executive officers, directors and designated employees of the Company and its
subsidiaries to make reasonably available for inspection during normal business
hours all relevant information reasonably requested by such representative for
the Notice Holders or any such broker-dealers, attorneys or accountants in
connection with such disposition, in each case as is customary for similar "due
diligence" examinations; provided, however, that such persons shall first agree
in writing with the Company pursuant to a customary confidentiality agreement
that any information that is reasonably designated by the Company in writing as
confidential at the time of delivery of such information shall be kept
confidential by such persons and shall be used solely for the purposes of
exercising rights under this Agreement, unless (i) disclosure of such
information is required by court or administrative order or is necessary to
respond to inquiries of regulatory authorities, (ii) disclosure of such
information is required by law (including any disclosure requirements pursuant
to federal securities laws in connection with the filing of any Registration
Statement or the use of any Prospectus referred to in this Agreement), (iii)
such information becomes generally available to the public other than as a
result of a disclosure or failure to safeguard by any such person or (iv) such
information becomes available to any such person from a source other than the
Company and such source is not bound by a confidentiality agreement; and
provided further, that the foregoing inspection and information gathering shall,
to the greatest extent possible, be coordinated on behalf of all the Notice
Holders and the other parties entitled thereto by the counsel referred to in
Section 5.

               (k) Comply with all applicable rules and regulations of the SEC
and make generally available to its securityholders earning statements (which
need not be audited) satisfying the provisions of Section 11(a) of the
Securities Act and Rule 158 thereunder (or any similar rule promulgated under
the Securities Act) no later than 45 days after the end of


                                       11
<PAGE>   12
any 12-month period (or 90 days after the end of any 12-month period if such
period is a fiscal year) commencing on the first day of the first fiscal quarter
of the Company commencing after the effective date of a Registration Statement,
which statements shall cover said 12-month periods.

               (l) Cooperate with each Notice Holder to facilitate the timely
preparation and delivery of certificates representing Registrable Securities
sold pursuant to a Registration Statement, and cause such Registrable Securities
to be in such denominations as are permitted by the Indenture and registered in
such names as such Notice Holder may request in writing at least two Business
Days prior to any sale of such Registrable Securities.

               (m) Provide a CUSIP number for all Registrable Securities covered
by each Registration Statement not later than the effective date of such
Registration Statement and provide the Trustee for the LYONs and the transfer
agent for the Common Stock with certificates for the Registrable Securities that
are in a form eligible for deposit with The Depository Trust Company.

               (n) Make reasonable effort to provide such information as is
required for any filings required to be made with the National Association of
Securities Dealers, Inc.

               (o) Upon (i) the filing of the Initial Shelf Registration
Statement and (ii) the effectiveness of the Initial Shelf Registration
Statement, announce the same, in each case by release to Reuters Economic
Services and Bloomberg Business News or other means of dissemination reasonably
expected to make such information known publicly.

               (p) Take all actions necessary, or reasonably requested by the
holders of a majority of the Registrable Securities being sold, in order to
expedite or facilitate disposition of such Registrable Securities; provided that
the Company shall not be required to take any action in connection with an
underwritten offering without its consent; and

               (q) Cause the Indenture to be qualified under the TIA not later
than the effective date of any Registration Statement; and in connection
therewith, cooperate with the Trustee to effect such changes to the Indenture as
may be required for the Indenture to be so qualified in accordance with the
terms of the TIA and execute, and use reasonable efforts to cause the Trustee to
execute, all documents as may be required to effect such changes, and all other
forms and documents required to be filed with the SEC to enable the Indenture to
be so qualified in a timely manner.

               SECTION 4. Holder's Obligations. Each Holder agrees, by
acquisition of the Registrable Securities, that no Holder of Registrable
Securities shall be entitled to sell any of such Registrable Securities pursuant
to a Registration Statement or to receive a Prospectus relating thereto, unless
such Holder has furnished the Company with a Notice and Questionnaire as
required pursuant to Section 2(d) hereof (including the information required to
be included in such Notice and Questionnaire) and the information set forth in
the next sentence. Each Notice Holder agrees promptly to furnish to the Company
all information required to be disclosed in order to make the information
previously furnished to the


                                       12
<PAGE>   13
Company by such Notice Holder not misleading, any other information regarding
such Notice Holder and the distribution of such Registrable Securities as may be
required to be disclosed in the Registration Statement under applicable law or
pursuant to SEC comments and any information otherwise required by the Company
to comply with applicable law or regulations. Each Holder further agrees,
following termination of the Effectiveness Period, to notify the Company within
10 business days of request, of the amount of Registrable Securities sold
pursuant to the Registration Statement and, in the absence of a response, the
Company may assume that all of the Holder's Registrable Securities were so sold.

               SECTION 5. Registration Expenses. The Company shall bear all fees
and expenses incurred in connection with the performance by the Company of its
obligations under Sections 2 and 3 of this Agreement whether or not any of the
Registration Statements are declared effective. Such fees and expenses shall
include, without limitation, (i) all registration and filing fees (including,
without limitation, fees and expenses (x) with respect to filings required to be
made with the National Association of Securities Dealers, Inc. and (y) of
compliance with federal and state securities or Blue Sky laws to the extent such
filings or compliance are required pursuant to this Agreement (including,
without limitation, reasonable fees and disbursements of the counsel specified
in the next sentence in connection with Blue Sky qualifications of the
Registrable Securities under the laws of such jurisdictions as the Notice
Holders of a majority of the Registrable Securities being sold pursuant to a
Registration Statement may designate)), (ii) printing expenses (including,
without limitation, expenses of printing certificates for Registrable Securities
in a form eligible for deposit with The Depository Trust Company), (iii)
duplication expenses relating to copies of any Registration Statement or
Prospectus delivered to any Holders hereunder, (iv) fees and disbursements of
counsel for the Company in connection with the Shelf Registration Statement, and
(v) reasonable fees and disbursements of the Trustee and its counsel and of the
registrar and transfer agent for the Common Stock. In addition, the Company
shall bear or reimburse the Notice Holders for the fees and disbursements of one
firm of legal counsel for the Holders, which shall, upon the written consent of
the Initial Purchaser (which shall not be unreasonably withheld), be a
nationally recognized law firm experienced in securities law matters designated
by the Company. In addition, the Company shall pay the internal expenses of the
Company (including, without limitation, all salaries and expenses of officers
and employees performing legal or accounting duties), the expense of any annual
audit, the fees and expenses incurred in connection with the listing of the
Registrable Securities on any securities exchange on which the same securities
of the Company are then listed and the fees and expenses of any person,
including special experts, retained by the Company.

               SECTION 6. Indemnification; Contribution.

               (a) The Company agrees to indemnify and hold harmless the Initial
Purchaser and each holder of Registrable Securities and each person, if any, who
controls the Initial Purchaser or any holder of Registrable Securities within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act, as follows:

               (i) against any and all loss, liability, claim, damage and
          expense whatsoever, as incurred, arising out of any untrue statement
          or alleged untrue statement of a material fact contained in the
          Registration Statement (or any


                                       13
<PAGE>   14
          amendment thereto), or the omission or alleged omission therefrom of a
          material fact necessary in order to make the statements therein, in
          light of the circumstances under which they were made, not misleading
          or arising out of any untrue statement or alleged untrue statement of
          a material fact included in any preliminary prospectus or the
          Prospectus (or any amendment or supplement thereto), or the omission
          or alleged omission therefrom of a material fact necessary in order to
          make the statements therein, in the light of the circumstances under
          which they were made, not misleading;

               (ii) against any and all loss, liability, claim, damage and
          expense whatsoever, as incurred, to the extent of the aggregate amount
          paid in settlement of any litigation, or any investigation or
          proceeding by any governmental agency or body, commenced or
          threatened, or of any claim whatsoever based upon any such untrue
          statement or omission, or any such alleged untrue statement or
          omission, provided that (subject to Section 6(d) below) any such
          settlement is effected with the prior written consent of the Company;
          and

               (iii) subject to Section 6(c) below, against any and all expense
          whatsoever, as incurred (including the fees and disbursements of
          counsel), reasonably incurred in investigating, preparing or defending
          against any litigation, or any investigation or proceeding by any
          governmental agency or body, commenced or threatened, or any claim
          whatsoever based upon any such untrue statement or omission, or any
          such alleged untrue statement or omission, to the extent that any such
          expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by or
on behalf of the Initial Purchaser, such holder of Registrable Securities (which
also acknowledges the indemnity provisions herein) or any person, if any, who
controls the Initial Purchaser or any such holder of Registrable Securities
expressly for use in the Registration Statement (or any amendment thereto), or
any preliminary prospectus or the Prospectus (or any amendment or supplement
thereto); provided, further, that this indemnity agreement shall not apply to
any loss, liability, claim, damage or expense (1) arising from an offer or sale
of Registrable Securities occurring during a Deferral Period, if a Deferral
Notice was given to such Notice Holder in accordance with Section 8(b), or (2)
if the Holder fails to deliver at or prior to the written confirmation of sale,
the most recent Prospectus, as amended or supplemented, and such Prospectus, as
amended or supplemented, corrected such untrue statement or omission or alleged
untrue statement or omission of a material fact and the delivery thereof was
required by law and would have constituted a complete defense to the claim in
respect of such untrue statement or omission or alleged untrue statement or
omission.

               (b) In connection with any Shelf Registration in which a holder,
including, without limitation, the Initial Purchaser, of Registrable Securities
is participating, in furnishing information relating to such holder of
Registrable Securities to the Company in writing expressly for use in such
Registration Statement, any preliminary prospectus, the


                                       14
<PAGE>   15
Prospectus or any amendments or supplements thereto, the holders of such
Registrable Securities agree, severally and not jointly, to indemnify and hold
harmless the Initial Purchaser and each person, if any, who controls the Initial
Purchaser within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act and the Company, and each person, if any, who
controls the Company within the meaning of either such Section, against any and
all loss, liability, claim, damage and expense described in the indemnity
contained in subsection (a) of this Section, as incurred, but only with respect
to untrue statements or omissions, or alleged untrue statements or omissions,
made in the Registration Statement (or any amendment thereto), or any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto) in reliance upon and in conformity with written information furnished
to the Company by or on behalf of such holder of Registrable Securities (which
also acknowledges the indemnity provisions herein) or any person, if any, who
controls any such holder of Registrable Securities expressly for use in the
Registration Statement (or any amendment thereto) or such preliminary prospectus
or the Prospectus (or any amendment or supplement thereto).

               The Initial Purchaser agrees to indemnify and hold harmless the
Company, the holders of Registrable Securities, and each person, if any, who
controls the Company or any holder of Registrable Securities within the meaning
of either Section 15 of the Securities Act or Section 20 of the Exchange Act
against any and all loss, liability, claim, damage and expense described in the
indemnity contained in subsection (a) of this Section, as incurred, but only
with respect to untrue statements or omissions, or alleged untrue statements or
omissions, made in the Registration Statement (or any amendment thereto), or any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto) in reliance upon and in conformity with written information furnished
to the Company or on behalf of by the Initial Purchaser expressly for use in the
Registration Statement (or any amendment thereto) or such preliminary prospectus
or the Prospectus (or any amendment or supplement thereto).

               (c) Each indemnified party shall give notice as promptly as
reasonably practicable to each indemnifying party of any action commenced
against it in respect of which indemnity may be sought hereunder, but failure to
so notify an indemnifying party shall not relieve such indemnifying party from
any liability hereunder to the extent it is not materially prejudiced as a
result thereof and in any event shall not relieve it from any liability which it
may have otherwise than on account of this indemnity agreement. The indemnifying
party, upon request of the indemnified party, shall retain counsel reasonably
satisfactory to the indemnified party to represent the indemnified party and any
others the indemnifying party may designate in such proceeding and shall pay the
fees and disbursements of such counsel related to such proceeding. In any such
proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the indemnifying party
shall not, in respect of the legal expenses of any indemnified party in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for


                                       15
<PAGE>   16
(a) the reasonable fees and expenses of more than one separate firm (in addition
to any local counsel) for the Initial Purchaser, Holders of Registrable
Securities, and all persons, if any, who control the Initial Purchaser or
Holders of Registrable Securities within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act (b) the reasonable fees and
expenses of more than one separate firm (in addition to any local counsel) for
the Company, its directors, and each person, if any, who controls the Company
within the meaning of either such Section, and that all such reasonable fees and
expenses shall be reimbursed as they are incurred. In the case of any such
separate firm for the Initial Purchaser, Holders of Registrable Securities, and
control persons of the Initial Purchaser and Holders of Registrable Securities,
such firm shall be designated in writing by the Initial Purchaser. In the case
of any such separate firm for the Company, and such directors, officers and
control persons of the Company, such firm shall be designated in writing by the
Company. No indemnifying party shall, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section 6 (whether or not the indemnified parties are actual or
potential parties thereto), unless such settlement, compromise or consent (i)
includes an unconditional release of each indemnified party from all liability
arising out of such litigation, investigation, proceeding 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) If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 6(a)(ii) effected without its
written consent if (i) such settlement is entered into more than 60 days after
receipt by such indemnifying party of aforesaid request, (ii) such indemnifying
party shall have received notice of the terms of such settlement at least 30
days prior to such settlement being entered into and (iii) such indemnifying
party shall not have reimbursed such indemnified party in accordance with such
request prior to the date of such settlement; provided, that an indemnifying
party shall not be liable for any such settlement effected without its consent
if such indemnifying party (1) reimburses such indemnified party in accordance
with such request to the extent it considers such request to be reasonable and
(2) provides written notice to the indemnified party describing any unpaid
balance it believes is unreasonable and the reasons therefor, in each case prior
to the date of such settlement.

               (e) If the indemnification to which an indemnified party is
entitled under this Section 6 is for any reason unavailable to or insufficient
although applicable in accordance with its terms to hold harmless an indemnified
party in respect of any losses, liabilities, claims, damages or expenses
referred to therein, then each indemnifying party shall contribute to the
aggregate amount of such losses, liabilities, claims, damages and expenses
incurred by such indemnified party, as incurred, in such proportion as is
appropriate to reflect the relative fault of the indemnifying party or parties
on the one hand and of the indemnified party on the other hand in connection
with the statements or omissions which resulted in such losses, liabilities,
claims, damages or expenses, as well as any other relevant equitable
considerations.


                                       16
<PAGE>   17
               The relative fault of the Company on the one hand and the holders
of the Registrable Securities or the Initial Purchaser on the other hand shall
be determined by reference to, among other things, whether any such untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact relates to information supplied by the Company or by the
holder of the Registrable Securities or the Initial Purchaser 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 contribution pursuant to this Section 6(e) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to above in this Section 6(e). The
aggregate amount of losses, liabilities, claims, damages, and expenses incurred
by an indemnified party and referred to above in this Section 6(e) shall be
deemed to include any out-of-pocket legal or other expenses reasonably incurred
by such indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.

               Notwithstanding the provisions of this Section 6, neither the
holder of any Registrable Securities nor the Initial Purchaser, shall be
required to indemnify or contribute any amount in excess of the amount by which
the total price at which the Registrable Securities sold by such holder of
Registrable Securities or by the Initial Purchaser, as the case may be, and
distributed to the public were offered to the public exceeds the amount of any
damages that such holder of Registrable Securities or the Initial Purchaser 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.

               For purposes of this Section 6(e), each person, if any, who
controls the Initial Purchaser or any holder of Registrable Securities within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act shall have the same rights to contribution as the Initial Purchaser or such
holder, and each person, if any, who controls the Company within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act shall have
the same rights to contribution as the Company.

               SECTION 7. Information Requirements. The Company covenants that,
if at any time before the end of the Effectiveness Period the Company is not
subject to the reporting requirements of the Exchange Act, it will cooperate
with any Holder of Registrable Securities and take such further reasonable
action as any Holder of Registrable Securities may reasonably request in writing
(including, without limitation, making such reasonable representations as any
such Holder 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 limitation of the exemptions provided by
Rule 144 and Rule


                                       17
<PAGE>   18
144A under the Securities Act and customarily taken in connection with
sales pursuant to such exemptions. Upon the written request of any Holder of
Registrable Securities, the Company shall deliver to such Holder a written
statement as to whether it has complied with such filing requirements, unless
such a statement has been included in the Company's most recent report required
to be filed and filed pursuant to Section 13 or Section 15(d) of Exchange Act.
Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to
require the Company to register any of its securities under any section of the
Exchange Act.

               SECTION 8. Miscellaneous; No Conflicting Agreements. The Company
is not, as of the date hereof, a party to, nor shall it, on or after the date of
this Agreement, enter into, any agreement with respect to its securities that
conflicts with the rights granted to the Holders of Registrable Securities in
this Agreement. The Company represents and warrants that the rights granted to
the Holders of Registrable Securities hereunder do not in any way conflict with
the rights granted to the holders of the Company's securities under any other
agreements.

               (a) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the Company has obtained the written consent of Holders
of a majority of the then outstanding Underlying Common Stock constituting
Registrable Securities (with Holders of LYONs or Semi-annual Coupon Notes deemed
to be the Holders, for purposes of this Section, of the number of outstanding
shares of Underlying Common Stock into which such LYONs or Semi-annual Coupon
Notes are or would be convertible or exchangeable as of the date on which such
consent is requested). Notwithstanding the foregoing, a waiver or consent to
depart from the provisions hereof with respect to a matter that relates
exclusively to the rights of Holders of Registrable Securities whose securities
are being sold pursuant to a Registration Statement and that does not directly
or indirectly affect the rights of other Holders of Registrable Securities may
be given by Holders of at least a majority of the Registrable Securities being
sold by such Holders pursuant to such Registration Statement; provided, that the
provisions of this sentence may not be amended, modified, or supplemented except
in accordance with the provisions of the immediately preceding sentence. Each
Holder of Registrable Securities outstanding at the time of any such amendment,
modification, supplement, waiver or consent or thereafter shall be bound by any
such amendment, modification, supplement, waiver or consent effected pursuant to
this Section 8(b), whether or not any notice, writing or marking indicating such
amendment, modification, supplement, waiver or consent appears on the
Registrable Securities or is delivered to such Holder.

               (b) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand delivery, by telecopier, by
courier guaranteeing overnight delivery or by first-class mail, return receipt
requested, and shall be deemed given (i) when made, if made by hand delivery,
(ii) upon confirmation, if made by telecopier, (iii) one (1) Business Day after
being deposited with such courier, if made by overnight courier or (iv) on the
date indicated on the notice of receipt, if made by first-class mail, to the
parties as follows:

such Holder to the Company in a Notice and Questionnaire or any amendment
thereto;
