Issuer shall at the written request of Required Holders file a registration

Registrable Notes for a like aggregate principal amount at maturity of debt

Commission to effect or maintain the qualification thereof under the TIA and
<PAGE>

                                      -6-

which has been qualified under the TIA and (B) that is otherwise in form and
substance reasonably satisfactory to the Required Holders (which must be
considered in good faith within time frames that permit the Issuer to comply
with its obligations hereunder) containing the covenants set forth in Sections
6.01(a), (b), (c) and (e) (for delivery to the Trustee only) and (g) and
Sections 7 and 8, the events of default and remedies set forth in Section 11.01,
the redemption provisions, related definitions and other material terms of the
Notes (excluding, in any event, Sections 3, 4, 5, 6.01(d) and (f), 9 and 13) as
are set forth in the Purchase Agreement, customary "boilerplate" indenture
provisions and no others, except that the Exchange Notes shall have been
registered pursuant to an effective Registration Statement under the Securities
Act and shall contain no restrictive legend thereon, except as otherwise
specifically required by the other provisions of this Agreement.  The Issuer
shall not be obligated to effect more than one Exchange Offer.  The Exchange
Offer shall be registered under the Securities Act on the appropriate form (the
"Exchange Registration Statement") and shall comply with all applicable tender
 -------------------------------
offer rules and regulations under the Exchange Act. The Issuer agrees to use its
reasonable best efforts to (i) file the initial Exchange Registration Statement
with the Commission on or prior to the Filing Date; (ii) cause the Exchange
Registration Statement to be declared effective under the Securities Act on or
before the Effectiveness Date; (iii) keep the Exchange Offer open for at least
20 Business Days (or longer if required by applicable law) after the date that
notice of the Exchange Offer is first mailed to Holders; and (iv) consummate the
Exchange Offer on or prior to the 45th day following the date on which the
Exchange Registration Statement is declared effective. If after such Exchange
Registration Statement is initially declared effective by the Commission, the
Exchange Offer or the issuance of the Exchange Notes thereunder is interfered
with by any stop order, injunction or other order or requirement of the
Commission or any other governmental agency or court, then such Exchange
Registration Statement shall be deemed not to have become effective for purposes
of this Agreement. Each Holder who participates in the Exchange Offer will be
required to represent that any Exchange Notes received by it will be acquired in
the ordinary course of its business, that at the time of the consummation of the
Exchange Offer such Holder will have no arrangement or understanding with any
Person to participate in the distribution of the Exchange Notes, that such
Holder is not an affiliate of the Issuer within the meaning of the Securities
Act and any additional representations that in the written opinion of counsel to
the Issuer are necessary under then-existing interpretations of the Commission
in order for the Exchange Registration Statement to be declared effective. Upon
consummation of the Exchange Offer in accordance with this Section 2, the
provisions of this Agreement shall continue to apply, mutatis mutandis, solely
with respect to Registrable Notes that are Exchange Notes held by Participating
Broker-Dealers, and the Issuer shall have no further obligation to register
Registrable Notes (other than in respect of any Restricted Exchange Notes)
pursuant to Section 3 of this Agreement. No securities other than the Exchange
Notes shall be included in the Exchange Registration Statement.
<PAGE>

                                      -7-

          (b)  The Issuer shall include within the Prospectus contained in the
Exchange Registration Statement a section entitled "Plan of Distribution,"
reasonably acceptable to the Purchasers, which shall contain a summary statement
of the positions taken or policies made by the Commission with respect to the
potential "underwriter" status of any broker-dealer that is the beneficial owner
(as defined in Rule 13d-3 under the Exchange Act) of Exchange Notes received by
such broker-dealer in the Exchange Offer (a "Participating Broker-Dealer"),
                                             ---------------------------
whether such positions or policies have been publicly disseminated by the
Commission or such positions or policies, in the judgment of the Purchasers,
represent the prevailing views of the Commission. Such "Plan of Distribution"
section shall also allow, to the extent permitted by applicable policies and
regulations of the Commission, the use of the Prospectus by all Persons subject
to the prospectus delivery requirements of the Securities Act, including, to the
extent so permitted, all Participating Broker-Dealers and include a statement
describing the manner in which Participating Broker-Dealers may resell the
Exchange Notes.

          The Issuer shall use its reasonable best efforts to keep the Exchange
Registration Statement effective and to amend and supplement the Prospectus
contained therein, in order to permit such Prospectus to be lawfully delivered
by all Persons subject to the prospectus delivery requirements of the Securities
Act for such period of time as such Persons must comply with such requirements
in connection with offers and sales of the Exchange Notes, which period shall
not exceed 180 days from the date on which the Exchange Offer commences (the
"Applicable Period").  The Issuer shall provide sufficient copies of the latest
 -----------------
version of such Prospectus to such Persons, promptly upon request, and in no
event later than three (3) Business Days after such request, at any time during
such period.

          Interest on the Exchange Notes will accrete from the last interest
accretion date on which interest accreted on the Notes surrendered in exchange
therefor or, if no interest has accreted on the Notes, then from the Closing
Time.

          In connection with the Exchange Offer, the Issuer shall:

             (1) mail to each Holder a copy of the Prospectus forming part of
     the Exchange Registration Statement, together with an appropriate letter of
     transmittal and related documents;

             (2) utilize the services of a depositary for the Exchange Offer
     with an address in the Borough of Manhattan, The City of New York, which
     may be the Trustee or an affiliate thereof;

             (3) permit Holders to withdraw tendered Registrable Notes at any
     time prior to the close of business, New York time, on the last Business
     Day on which the Exchange Offer shall remain open; and
<PAGE>

                                      -8-

             (4) otherwise comply in all material respects with all applicable
     laws.

          As soon as practicable after the close of the Exchange Offer, the
Issuer shall:

             (1) accept for exchange all Registrable Notes validly tendered and
     not validly withdrawn pursuant to the Exchange Offer;

             (2) deliver to the Trustee for cancellation all Registrable Notes
     so accepted for exchange; and

             (3) cause the Trustee to authenticate and deliver promptly to each
     Holder tendering such Registrable Notes, Exchange Notes, equal in aggregate
     principal amount at maturity to the Notes of such Holder so accepted for
     exchange.

          The Exchange Notes will be issued under the Indenture and the Exchange
Notes, and the Notes, if any, will vote and consent together on all matters as
one class, and none of the Exchange Notes or the Notes, if any, will have the
right to vote or consent as a separate class on any matter.

          (c)  In addition to conducting the Exchange Offer provided for in
Section 2(a) above, if (i) because of any change in law or in currently
prevailing interpretations of the Commission, the Issuer reasonably determines
in good faith, based upon written advice of qualified counsel (including,
without limitation, qualified in-house counsel), that it is not permitted to
effect the Exchange Offer; (ii) the Exchange Offer is not commenced on or prior
to the Effectiveness Date; (iii) the Exchange Offer is, for any reason, not
consummated on or prior to the 180th day after the Notice Date; (iv) in the case
of any Holder that participates in an Exchange Offer, the Issuer receives an
opinion of counsel (including, without limitation, qualified in-house counsel)
to such Holder reasonably acceptable to the Issuer to the effect that such
Holder did not receive Exchange Notes on the date of the exchange that may be
sold without restriction under federal securities laws; or (v) any Holder is an
Affiliate of the Issuer, then, (x) in the case of each of clause (i) through
(iv) of this sentence, the Issuer shall upon the request of the Required Holders
and (y) in the case of clause (v) of this sentence, the Issuer shall upon the
request of a Holder, in each case, at any time after the earlier of: (A)
February 2, 2001 and (B) the consummation of an Initial Public Equity Offering,
promptly deliver to the Holders a written notice thereof (the "Shelf Notice")
                                                               ------------
and shall file a Shelf Registration pursuant to Section 3; provided, however,
that the Issuer shall not be required to effect more than two Shelf
Registrations pursuant to clause (v) of this Section 2(c).

3.   Shelf Registration
     ------------------

          If a Shelf Notice is delivered as contemplated by Section 2(c), then:
<PAGE>

                                      -9-

          (a)  Shelf Registration.  The Issuer shall (i) privately exchange the
               ------------------
     Notes for Exchange Notes issued pursuant to the Indenture (such Exchange
     Notes to contain any appropriate restrictive legends as required by law) (a
     "Shelf Exchange") and (ii) as promptly as reasonably practicable file with
      --------------
     the Commission a Registration Statement for an offering to be made on a
     continuous basis pursuant to Rule 415 covering all of the Registrable Notes
     issued in the Shelf Exchange (the "Initial Shelf Registration"). The Issuer
                                        --------------------------
     shall file with the Commission the Initial Shelf Registration within 30
     days of the delivery of the Shelf Notice and shall use its reasonable best
     efforts to cause such Shelf Registration to be declared effective,
     supplemented, amended and current under the Securities Act on or prior to
     the Effectiveness Date. The Initial Shelf Registration shall be on Form S-1
     or another appropriate form permitting registration of all Exchange Notes
     constituting Registrable Notes for resale by Holders in the manner or
     manners designated by them (including, without limitation, one or more
     underwritten offerings). The Issuer shall not permit any securities other
     than the Registrable Notes to be included in any Shelf Registration. The
     Issuer shall use its reasonable best efforts to keep the Initial Shelf
     Registration continuously effective, supplemented, amended and current
     under the Securities Act until the date which is two years from the Closing
     Time (the "Effectiveness Period") or such shorter period ending when (i)
                --------------------
     all Registrable Notes covered by the Initial Shelf Registration have been
     sold in the manner set forth and as contemplated in the Initial Shelf
     Registration or (ii) a Subsequent Shelf Registration covering all of the
     Registrable Notes has been declared effective under the Securities Act.
     Any Exchange Notes issued under the Indenture in connection with a Shelf
     Exchange will vote and consent together on all matters as one class with
     Holders of Notes and Exchange Notes.  Interest on Registrable Notes issued
     in the Shelf Exchange will accrue interest from the last interest payment
     date on which interest was paid on the Notes surrendered in exchange
     therefor or, if no interest has been paid on the Notes, then from the
     Closing Time.

          (b)  Subsequent Shelf Registrations. If the Initial Shelf Registration
               ------------------------------
     or any Subsequent Shelf Registration (as defined) ceases to be effective
     for any reason at any time during the Effectiveness Period (other than
     because of the sale of all of the securities registered thereunder), then
     the Issuer shall use its commercially reasonable efforts to obtain the
     prompt withdrawal of any order suspending the effectiveness thereof and in
     any event shall within 30 days of such cessation of effectiveness amend the
     Shelf Registration in a manner to obtain the withdrawal of the order
     suspending the effectiveness thereof, or file an additional "shelf"
     Registration Statement pursuant to Rule 415 covering all of the Registrable
     Notes (a "Subsequent Shelf Registration").  If a Subsequent Shelf
               -----------------------------
     Registration is filed, then the Issuer shall use its commercially
     reasonable efforts to cause the Subsequent Shelf Registration to be
     declared effective as soon as practicable after such filing and to keep
     such Subsequent Shelf Registration
<PAGE>

                                      -10-

     continuously effective for a period equal to the number of days in the
     Effectiveness Period less the aggregate number of days during which the
     Initial Shelf Registration or any Subsequent Shelf Registrations was
     previously continuously effective. As used herein the term "Shelf
                                                                 -----
     Registration" means the Initial Shelf Registration and any Subsequent
     ------------
     Shelf Registration.

          (c)  Supplements and Amendments.  The Issuer shall promptly supplement
               --------------------------
     and amend any Shelf Registration if required by the rules, regulations or
     instructions applicable to the registration form used for such Shelf
     Registration, if required by the Securities Act, or if reasonably requested
     by the Holders of a majority in aggregate principal amount at maturity of
     the Registrable Notes covered by such Shelf Registration or by any
     underwriter of such Registrable Notes, in each case, with the Issuer's
     consent, which consent shall not be unreasonably withheld or delayed.

4.   Special Interest
     ----------------

          (a)  The Issuer and the Purchasers agree that the Holders of
Registrable Notes will suffer damages if the Issuer fails to fulfill its
obligations under Section 2 or Section 3 hereof and that it would not be
feasible to ascertain the extent of such damages with precision. Accordingly,
the Issuer agrees to pay, in cash, as liquidated damages, Special Interest on
the Registrable Notes ("Special Interest") under the circumstances and to the
                        ----------------
extent set forth below (each of which shall be given independent effect):

             (i) if (A) the Exchange Registration Statement has not been filed
     on or prior to the Filing Date or (B) notwithstanding that the Issuer has
     consummated or will consummate an Exchange Offer, the Issuer is required to
     file an Initial Shelf Registration and such Shelf Registration is not filed
     on or prior to the 90th day (or 30 days, if the Filing Date has occurred
     prior to the Shelf Notice being given) after delivery of the Shelf Notice,
     then, in the case of subclause (A), commencing on the day after the Filing
     Date or, in the case of subclause (B), commencing on the 91st day (or the
     31st day if the Filing Date has occurred prior to the Shelf Notice being
     given) following delivery of the Shelf Notice, Special Interest shall
     accrue on the Registrable Notes over and above the stated interest at a
     rate of 0.50% per annum of the Accreted Value of the Registrable Notes for
     the first 90 days immediately following the Filing Date or such 91st day
     (or the 31st day if the Filing Date has occurred prior to the Shelf Notice
     being given), as the case may be, such Special Interest rate increasing by
     an additional 0.25% per annum of the Accreted Value of the Registrable
     Notes at the beginning of each subsequent 90-day period;

             (ii) if (A) the Exchange Registration Statement is not declared
     effective on or prior to the Effectiveness Date applicable thereto or (B)
     notwithstanding that the Is-
<PAGE>

                                      -11-

     suer has consummated or will consummate an Exchange Offer, the Issuer is
     required to file an Initial Shelf Registration and such Shelf Registration
     is not declared effective by the Commission on or prior to the applicable
     Effectiveness Date, then, commencing on the day after such applicable
     Effectiveness Date, Special Interest shall accrue on the Registrable Notes
     over and above the stated interest at a rate of 0.50% per annum of the
     Accreted Value of the Registrable Notes for the first 90 days immediately
     following the day after the applicable Effectiveness Date, such Special
     Interest rate increasing by an additional 0.25% per annum of the Accreted
     Value of the Registrable Notes at the beginning of each subsequent 90-day
     period; and

             (iii) if (A) the Issuer has not exchanged Exchange Notes for all
     Notes validly tendered in accordance with the terms of the Exchange Offer
     on or prior to 45 days after the date on which the Exchange Registration
     Statement was declared effective; (B) the Exchange Registration Statement
     ceases to be effective prior to consummation of the Exchange Offer; or (C)
     if applicable, a Shelf Registration has been declared effective and such
     Shelf Registration ceases to be effective at any time during the
     Effectiveness Period, then Special Interest shall accrue on the Registrable
     Notes over and above the stated interest at a rate of 0.50% per annum of
     the Accreted Value of the Registrable Notes for the first 90 days
     commencing on the (x) 91st day after such effective date in the case of (A)
     above or (y) the day such Exchange Registration Statement or Shelf
     Registration ceases to be effective in the case of (B) and (C) above, such
     Special Interest rate increasing by an additional 0.25% per annum of the
     Accreted Value of the Registrable Notes at the beginning of each such
     subsequent 90-day period;

provided, however, that the Special Interest rate on the Registrable Notes may
not exceed in the aggregate 2.00% per annum of the Accreted Value of the
Registrable Notes; provided, further, that (1) upon the filing of the Exchange
Registration Statement or each Shelf Registration (in the case of (i) above);
(2) upon the effectiveness of the Exchange Registration Statement or each Shelf
Registration, as the case may be (in the case of (ii) above); or (3) upon the
exchange of Exchange Notes for all Registrable Notes tendered (in the case of
(iii)(A) above) or upon the effectiveness of an Exchange Registration Statement
or Shelf Registration which had ceased to remain effective (in the case of
(iii)(B) and (C) above), Special Interest on any Registrable Notes then accruing
Special Interest as a result of such clause (or the relevant subclause thereof),
as the case may be, shall cease to accrue.

          (b)  The Issuer shall notify the Holders within three business days
after each and every date on which an event occurs in respect of which Special
Interest is required to be paid (an "Event Date").  Any amounts of Special
                                     ----------
Interest due pursuant to (a)(i), (a)(ii) or (a)(iii) of this Section 4 will be
payable in cash semi-annually on each February 1 and August 1 (to the Holders of
Registrable Notes of record on the regular record date therefor (as
<PAGE>

                                      -12-

specified in the Purchase Agreement) immediately preceding such dates),
commencing with the first such date occurring after any such Special Interest
commences to accrue. The amount of Special Interest will be determined by
applying the applicable Special Interest rate to the Accreted Value of the Notes
outstanding on a daily basis during such period but utilizing a 360-day year
comprised of 12 30-day months. Notwithstanding the fact that any Registrable
Notes for which Special Interest is due thereafter cease to be Registrable
Notes, all obligations of the Issuer to pay Special Interest with respect to
such Registrable Notes shall survive until such time as such obligations with
respect to such Registrable Notes shall have been satisfied in full.

          (c)  The parties hereto agree that the Special Interest provided for
in this Section 4 constitutes the sole and exclusive remedy for a breach of
Sections 2 and 3 hereof and is a reasonable estimate of the damages that may be
incurred by Holders of Registrable Notes in the circumstances set forth in
Section 4(a).

5.   Registration Procedures
     -----------------------

          In connection with the filing of any Registration Statement pursuant
to Sections 2 or 3 hereof, the Issuer shall effect such registrations to permit
the sale of such securities covered thereby in accordance with the intended
method or methods of disposition thereof, and pursuant thereto and in connection
with any Registration Statement filed by the Issuer hereunder, the Issuer shall:

          (a)  Prepare and file with the Commission prior to the Filing Date,
     the Exchange Registration Statement or Shelf Registration, as the case may
     be, as prescribed by Section 2 or 3 and use its reasonable best efforts to
     cause each such Registration Statement to become effective and remain
     effective as provided herein; provided that, if (i) a Shelf Registration is
     filed pursuant to Section 3 or (ii) a Prospectus contained in an Exchange
     Registration Statement filed pursuant to Section 2 is required to be
     delivered under the Securities Act by any Participating Broker-Dealer who
     seeks to sell Exchange Notes during the Applicable Period and has advised
     the Issuer that it is a Participating Broker-Dealer, before filing any
     Registration Statement or Prospectus or any amendments or supplements
     thereto, then the Issuer shall, if requested, furnish to and afford the
     Holders of the Registrable Notes to be registered pursuant to such Shelf
     Registration or each such Participating Broker-Dealer, as the case may be,
     covered by such Registration Statement, their counsel and the managing
     underwriters, if any, a reasonable opportunity to review copies of all such
     documents (including copies of any documents to be incorporated by
     reference therein and all exhibits thereto) proposed to be filed (in each
     case at least five (5) Business Days prior to such filing). The Issuer
     shall not file any such Registration Statement or Prospectus or any
     amendments or supplements thereto if the Holders of a majority in aggregate
     principal amount at
<PAGE>

                                      -13-

     maturity of the Registrable Notes covered by such Registration Statement,
     or any such Participating Broker-Dealer, as the case may be, their counsel,
     or the managing underwriters, if any, shall reasonably object within five
     (5) Business Days of their receipt of such materials.

          (b)  Prepare and file with the Commission such amendments and post-
     effective amendments to each Shelf Registration or Exchange Registration
     Statement, as the case may be, as may be necessary to keep such
     Registration Statement continuously effective for the Effectiveness Period
     or the Applicable Period, as the case may be; cause the related Prospectus
     to be supplemented by any Prospectus supplement required by applicable law,
     and as so supplemented to be filed pursuant to Rule 424 (or any similar
     provisions then in force) under the Securities Act; and comply with the
     provisions of the Securities Act and the Exchange Act applicable to it with
     respect to the disposition of all securities covered by such Registration
     Statement as so amended or in such Prospectus as so supplemented and with
     respect to the subsequent resale of any securities being sold by a
     Participating Broker-Dealer covered by any such Prospectus. The Issuer
     shall be deemed not to have used its reasonable best efforts to keep a
     Registration Statement effective during the Applicable Period if it
     voluntarily takes any action that would result in selling Holders of the
     Registrable Notes covered thereby or Participating Broker-Dealers seeking
     to sell Exchange Notes not being able to sell such Registrable Notes or
     such Exchange Notes during that period unless such action is required by
     applicable law, rule or regulation or unless the Issuer complies with this
     Agreement, including, without limitation, the provisions of paragraph 5(k)
     hereof and the last paragraph of Section 5.

          (c)  If (i) a Shelf Registration is filed pursuant to Section 3 or
     (ii) a Prospectus contained in an Exchange Registration Statement filed
     pursuant to Section 2 is required to be delivered under the Securities Act
     by any Participating Broker-Dealer who seeks to sell Exchange Notes during
     the Applicable Period from whom the Issuer has received written notice that
     it will be a Participating Broker-Dealer, notify the selling Holders of
     Registrable Notes and each such Participating Broker-Dealer, their counsel
     and the managing underwriters, if any, promptly (but in any event within
     three Business Days), and confirm such notice in writing, (A) when a
     Prospectus or any Prospectus supplement or post-effective amendment has
     been filed, and, with respect to a Registration Statement or any post-
     effective amendment, when the same has become effective (including in such
     notice a written statement that any Holder may, upon request, obtain,
     without charge, one conformed copy of such Registration Statement or post-
     effective amendment including financial statements and schedules, documents
     incorporated or deemed to be incorporated by reference and exhibits); (B)
     of the issuance by the Commission of any stop order suspending the
     effectiveness
<PAGE>

                                      -14-

     of a Registration Statement or of any order preventing or suspending the
     use of any preliminary prospectus or the initiation of any proceedings for
     that purpose; (C) if at any time when a prospectus is required by the
     Securities Act to be delivered in connection with sales of the Registrable
     Notes the representations and warranties of the Issuer contained in any
     agreement (including any underwriting agreement contemplated by Section
     5(n) hereof) cease to be true and correct in any material respect; (D) of
     the receipt by the Issuer of any notification with respect to the
     suspension of the qualification or exemption from qualification of a
     Registration Statement or any of the Registrable Notes or the Exchange
     Notes to be sold by any Participating Broker-Dealer for offer or sale in
     any jurisdiction, or the initiation or threatening of any proceeding for
     such purpose; (E) of the happening of any event, the existence of any
     condition or any information becoming known that makes any statement made
     in such Registration Statement or related Prospectus or any document
     incorporated or deemed to be incorporated therein by reference untrue in
     any material respect or that requires the making of any changes in, or
     amendments or supplements to, such Registration Statement, Prospectus or
     documents so that, in the case of the Registration Statement, it will 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 that, in the case of the Prospectus,
     it will 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 light of the circumstances under which they were
     made, not misleading; and (F) of the Issuer's reasonable determination that
     a post-effective amendment to a Registration Statement would be
     appropriate.

          (d)  If (i) a Shelf Registration is filed pursuant to Section 3 or
     (ii) a Prospectus contained in an Exchange Registration Statement filed
     pursuant to Section 2 is required to be delivered under the Securities Act
     by any Participating Broker-Dealer who seeks to sell Exchange Notes during
     the Applicable Period, use its reasonable best efforts to prevent the
     issuance of any order suspending the effectiveness of a Registration
     Statement or of any order preventing or suspending the use of a Prospectus
     or suspending the qualification (or exemption from qualification) of any of
     the Registrable Notes or the Exchange Notes to be sold by any Participating
     Broker-Dealer, for sale in any jurisdiction, and, if any such order is
     issued, to use its commercially reasonable efforts to obtain the withdrawal
     of any such order at the earliest possible date.

          (e)  If a Shelf Registration is filed pursuant to Section 3 and if
     requested by the managing underwriters, if any, or the Holders of a
     majority in aggregate principal amount at maturity of the Registrable Notes
     being sold in connection with an underwritten offering, (i) as promptly as
     practicable incorporate in a prospectus supplement or post-effective
     amendment such information or revisions to information therein re-
<PAGE>

                                      -15-

     lating to such underwriters or selling Holders as the managing
     underwriters, if any, or such Holders or their counsel reasonably request
     to be included or made therein; (ii) make all required filings of such
     prospectus supplement or such post-effective amendment as soon as
     practicable after the Issuer has received notification of the matters to be
     incorporated in such prospectus supplement or post-effective amendment and
     (iii) supplement or make amendments to such Registration Statement.

          (f)  If (i) a Shelf Registration is filed pursuant to Section 3 or
     (ii) a Prospectus contained in an Exchange Registration Statement filed
     pursuant to Section 2 is required to be delivered under the Securities Act
     by any Participating Broker-Dealer who seeks to sell Exchange Notes during
     the Applicable Period, furnish to each selling Holder of Registrable Notes
     and to each such Participating Broker-Dealer who so requests and to counsel
     and each managing underwriter, if any, without charge, one conformed copy
     of the Registration Statement or Registration Statements and each post-
     effective amendment thereto, including financial statements and schedules,
     and, if requested, all documents incorporated or deemed to be incorporated
     therein by reference and all exhibits.

          (g)  If (i) a Shelf Registration is filed pursuant to Section 3 or
     (ii) a Prospectus contained in an Exchange Registration Statement filed
     pursuant to Section 2 is required to be delivered under the Securities Act
     by any Participating Broker-Dealer, deliver to each selling Holder of
     Registrable Notes or each such Participating Broker-Dealer, as the case may
     be, their respective counsel, and the underwriters, if any, without charge,
     as many copies of the Prospectus or Prospectuses (including each form of
     preliminary prospectus) and each amendment or supplement thereto and any
     documents incorporated by reference therein as such Persons may reasonably
     request; and, subject to the last paragraph of this Section 5, the Issuer
     hereby consents to the use of such Prospectus and each amendment or
     supplement thereto by each of the selling Holders of Registrable Notes and
     each Participating Broker-Dealer, and the underwriters or agents, if any,
     and dealers (if any), in connection with the offering and sale of the
     Registrable Notes covered by, or the sale by Participating Broker-Dealers
     of the Exchange Notes pursuant to, such Prospectus and any amendment or
     supplement thereto.

          (h)  Prior to any public offering of Registrable Notes or any delivery
     of a Prospectus contained in the Exchange Registration Statement by any
     Participating Broker-Dealer who seeks to sell Exchange Notes during the
     Applicable Period, use its reasonable best efforts to register or qualify,
     and cooperate with the selling Holders of Registrable Notes and each such
     Participating Broker-Dealer, the underwriters, if any, and their respective
     counsel in connection with the registration or qualification (or exemption
     from such registration or qualification) of such Registrable Notes or Ex-
<PAGE>

                                      -16-

     change Notes, as the case may be, for offer and sale under the securities
     or Blue Sky laws of such jurisdictions within the United States as any
     selling Holder, Participating Broker-Dealer, or the managing underwriter or
     underwriters, if any, reasonably request in writing; provided that where
     Exchange Notes held by Participating Broker-Dealers or Registrable Notes
     are offered pursuant to an underwritten offering, counsel to the
     underwriters shall, at the cost and expense of the Issuer, perform the Blue
     Sky investigations and file registrations and qualifications required to be
     filed pursuant to this Section 5(h); keep each such registration or
     qualification (or exemption therefrom) effective during the period such
     Registration Statement is required to be kept effective and do any and all
     other acts or things reasonably necessary or advisable to enable the
     disposition in such jurisdictions of the Exchange Notes by Participating
     Broker-Dealers or the Registrable Notes covered by the applicable
     Registration Statement; provided that the Issuer shall not be required to
     (i) qualify generally to do business in any jurisdiction where it is not
     then so qualified; (ii) take any action that would subject it to general
     service of process in any such jurisdiction where it is not then so
     subject; or (iii) subject itself to taxation in excess of a nominal dollar
     amount in any such jurisdiction where it is not then so subject.

          (i)  If a Shelf Registration is filed pursuant to Section 3, cooperate
     with the selling Holders of Registrable Notes, any Participating Broker-
     Dealer and the managing underwriter or underwriters, if any, to facilitate
     the timely preparation and delivery of certificates representing
     Registrable Notes to be sold, which certificates shall not bear any
     restrictive legends and shall be in a form eligible for deposit with The
     Depository Trust Company; and enable such Registrable Notes to be in such
     denominations and registered in such names as the managing underwriter or
     underwriters, if any, or Holders may reasonably request.

          (j)  If (i) a Shelf Registration is filed pursuant to Section 3 or
     (ii) a Prospectus contained in an Exchange Registration Statement filed
     pursuant to Section 2 is required to be delivered under the Securities Act
     by any Participating Broker-Dealer who seeks to sell Exchange Notes during
     the Applicable Period, upon the occurrence of any event contemplated by
     paragraph 5(c)(E) or 5(c)(F) hereof, as promptly as practicable prepare and
     (subject to Section 5(a) hereof) file with the Commission, at the Issuer's
     sole expense, a supplement or post-effective amendment to the Registration
     Statement or a supplement to the related Prospectus or any document
     incorporated or deemed to be incorporated therein by reference, or file any
     other required document so that, as thereafter delivered to the purchasers
     of the Registrable Notes being sold thereunder or to the purchasers of the
     Exchange Notes to whom such Prospectus will be delivered by a Participating
     Broker-Dealer, any such Prospectus will not contain an untrue statement of
     a material fact or omit to state a material fact required to be stated
<PAGE>

                                      -17-

     therein or necessary to make the statements therein, in light of the
     circumstances under which they were made, not misleading.

          (k)  Prior to the effective date of the first Registration Statement
     relating to the Registrable Notes, (i) provide the Trustee with
     certificates for the Registrable Notes in a form eligible for deposit with
     The Depository Trust Company; (ii) provide a CUSIP number for the
     Registrable Notes; and (iii) provide copies of the form of Indenture to the
     Trustee and the Holders.

          (l)  In connection with an underwritten offering of Registrable Notes
     pursuant to a Shelf Registration, enter into an underwriting agreement as
     is customary in underwritten offerings of debt securities similar to the
     Notes and take all such other actions as are reasonably requested by the
     managing underwriter or underwriters in order to expedite the registration
     or the disposition of such Registrable Notes and, in such connection, (i)
     make such representations and warranties to the underwriters, with respect
     to the business of the Issuer and its subsidiaries and the Registration
     Statement, Prospectus and documents, if any, incorporated or deemed to be
     incorporated by reference therein, in each case, as are customarily made by
     companies to underwriters in underwritten offerings of debt securities
     similar to the Notes and confirm the same in writing if and when reasonably
     requested; (ii) obtain the opinion of counsel to the Issuer and updates
     thereof in form and substance reasonably satisfactory to the managing
     underwriter or underwriters, addressed to the underwriters covering the
     matters customarily covered in opinions requested in underwritten offerings
     of debt securities similar to the Notes; (iii) obtain "cold comfort"
     letters and updates thereof in form and substance reasonably satisfactory
     to the managing underwriter or underwriters from the independent certified
     public accountants of the Issuer (and, if necessary, any other independent
     certified public accountants of any subsidiary of the Issuer or of any
     business acquired by the Issuer for which financial statements and
     financial data are, or are required to be, included in the Registration
     Statement), addressed to each of the underwriters, such letters to be in
     customary form and covering matters of the type customarily covered in
     "cold comfort" letters in connection with underwritten offerings of debt
     securities similar to the Notes; (iv) if an underwriting agreement is
     entered into, the same shall contain indemnification provisions and
     procedures no less favorable than those set forth in Section 7 hereof (or
     such other provisions and procedures acceptable to Holders of a majority in
     aggregate principal amount at maturity of Registrable Notes covered by such
     Registration Statement, the managing underwriter or underwriters or agents
     and the Issuer) with respect to all parties to be indemnified pursuant to
     such Section 7; and (v) deliver such other documents and certificates as
     may be reasonably requested by the managing underwriter or underwriters or
     selling Holders to evidence compliance with the matters covered in clauses
     (i) through (iv) above

                                      -18-

     and with any customary conditions contained in any underwriting agreement
     entered into by the Issuer pursuant to this clause (l).

          (m)  If (i) a Shelf Registration is filed pursuant to Section 3 or
     (ii) a Prospectus contained in an Exchange Registration Statement filed
     pursuant to Section 2 is required to be delivered under the Securities Act
     by any Participating Broker-Dealer who seeks to sell Exchange Notes during
     the Applicable Period, make available for inspection by any selling Holder
     of such Registrable Notes being sold, and each Participating Broker-Dealer,
     any underwriter participating in any such disposition of Registrable Notes,
     if any, and any attorney, accountant or other agent retained by any such
     selling Holder, each Participating Broker-Dealer, as the case may be, or
     underwriter (collectively, the "Inspectors"), at the offices where normally
                                     ----------
     kept, during reasonable business hours, all financial and other records,
     pertinent corporate documents and properties of the Issuer and its
     subsidiaries (collectively, the "Records") as shall be reasonably necessary
                                      -------
     to enable them to exercise any applicable due diligence responsibilities,
     and cause the officers, directors and employees of the Issuer and its
     subsidiaries to supply all information reasonably requested by any such
     Inspector in connection with such Registration Statement.  Records which
     the Issuer determines, in good faith, to be confidential and any Records
     which it notifies the Inspectors are confidential shall not be disclosed by
     the Inspectors unless (i) the disclosure of such Records is necessary to
     avoid or correct a misstatement or omission in such Registration Statement;
     (ii) the release of such Records is ordered pursuant to a subpoena or other
     order from a court of competent jurisdiction; (iii) the information in such
     Records has been made generally available to the public other than as a
     result of a disclosure or failure to safeguard by such Inspector; or (iv)
     disclosure of such information is, in the opinion of counsel for any
     Inspector, necessary or advisable in connection with any action, claim,
     suit or proceeding, directly or indirectly, involving or potentially
     involving such Inspector and arising out of, based upon, related to, or
     involving this Agreement, or any transactions contemplated hereby or
     arising hereunder.  Each selling Holder of such Registrable Notes and each
     Participating Broker-Dealer will be required to agree that information
     obtained by it as a result of such inspections shall be deemed confidential
     and shall not be used by it as the basis for any market transactions in the
     securities of the Issuer unless and until such is made generally available
     to the public.  Each inspector, each selling Holder of such Registrable
     Notes and each Participating Broker-Dealer will be required to further
     agree that it will, upon learning that disclosure of such Records is sought
     in a court of competent jurisdiction pursuant to clauses (ii) or (iv) of
     the previous sentence or otherwise, give notice to the Issuer and allow the
     Issuer, at the Issuer's expense, to undertake appropriate action to obtain
     a protective order or otherwise prevent disclosure of the Records deemed
     confidential.

                                      -19-

          (n)  Provide an indenture trustee for the Registrable Notes or the
     Exchange Notes, as the case may be, and cause the Indenture or the trust
     indenture provided for in Section 2(a) and 3(a), as the case may be, to be
     qualified under the TIA not later than the effective date of the Exchange
     Offer or the first Registration Statement relating to the Registrable
     Notes; and in connection therewith, cooperate with the trustee under any
     such indenture and the Holders of the Registrable Notes, to effect such
     changes to such indenture as may be required from time to time for such
     indenture to be so qualified in accordance with the terms of the TIA; and
     execute, and use its commercially reasonable efforts to cause such 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 Commission to
     enable such indenture to be so qualified in a timely manner.

          (o)  Comply with all applicable rules and regulations of the
     Commission and make generally available to its securityholders earnings
     statements 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 any 12-month period
     (or 90 days after the end of any 12-month period if such period is a fiscal
     year) (i) commencing at the end of any fiscal quarter in which Registrable
     Notes are sold to underwriters in a firm commitment or best efforts
     underwritten offering and (ii) if not sold to underwriters in such an
     offering, commencing on the first day of the first fiscal quarter of the
     Issuer after the effective date of a Registration Statement, which
     statements shall cover said 12-month periods.

          (p)  Upon consummation of the Exchange Offer or a Shelf Exchange,
     obtain an opinion of counsel to the Issuer, in a form customary for
     underwritten transactions, addressed to the Trustee for the benefit of all
     Holders of Registrable Notes participating in the Exchange Offer or the
     Shelf Exchange, that the Exchange Notes or Registrable Notes, as the case
     may be, and the related indenture constitute legally valid and binding
     obligations of the Issuer, enforceable against the Issuer in accordance
     with their respective terms.

          (q)  If the Exchange Offer or the Shelf Exchange is to be consummated,
     upon delivery of the Registrable Notes by Holders to the Issuer (or to such
     other Person as directed by the Issuer) in exchange for the Exchange Notes
     or Registrable Notes, as the case may be, the Issuer shall mark, or cause
     to be marked, on the Registrable Notes being delivered for cancellation,
     that such Registrable Notes are being cancelled in exchange for the
     Exchange Notes or Registrable Notes issued in the Shelf Exchange, as the
     case may be; in no event shall Registrable Notes being delivered for
     cancellation be marked as paid or otherwise satisfied.
<PAGE>

                                      -20-

          (r)  Cooperate with each seller of Registrable Notes covered by any
     Registration Statement and each underwriter, if any, participating in the
     disposition of such Registrable Notes and their respective counsel in
     connection with any filings required to be made with the National
     Association of Securities Dealers, Inc.

          (s)  Use its reasonable best efforts to take all other steps necessary
     or advisable to effect the registration of the Registrable Notes covered by
     a Registration Statement contemplated hereby.

          The Issuer may require each seller of Registrable Notes as to which
any registration is being effected to furnish to the Issuer such information
regarding such seller and the distribution of such Registrable Notes as the
Issuer may, from time to time, reasonably request. The Issuer may exclude from
such registration the Registrable Notes of any seller who fails to furnish such
information within twenty (20) Business Days after receiving such request. With
respect to a Shelf Registration, no Holder who has failed to furnish such
information shall be entitled to the Special Interest provided for in Section 4
that would otherwise have accrued or be payable during the period of time
commencing with the end of such twenty-Business Day period ending on the date
such requested information is received by the Issuer. Each seller as to which
any Shelf Registration Statement is being effected agrees to furnish promptly to
the Issuer all information required to be disclosed in order to make the
information previously furnished to the Issuer by such seller not materially
misleading.

          Each Holder of Registrable Notes and each Participating Broker-Dealer
agrees by acquisition of such Registrable Notes or Exchange Notes to be sold by
such Participating Broker-Dealer, as the case may be, that, upon receipt of any
notice from the Issuer of the happening of any event of the kind described in
Section 5(c)(B), 5(c)(D), 5(c)(E), or 5(c)(F), such Holder will forthwith
discontinue disposition of such Registrable Notes covered by such Registration
Statement or Prospectus or Exchange Notes to be sold by such Holder or
Participating Broker-Dealer, as the case may be, and, in each case,
dissemination of such Prospectus until such Holder's or Participating Broker-
Dealer's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 5(k), or until it is advised in writing (the "Advice")
                                                                      ------
by the Issuer that the use of the applicable Prospectus may be resumed, and has
received copies of any amendments or supplements thereto. In the event the
Issuer shall give any such notice, each of the Effectiveness Period and the
Applicable Period shall be extended by the number of days during such periods
from and including the date of the giving of such notice to and including the
date when each seller of Registrable Notes covered by such Registration
Statement or Exchange Notes to be sold by such Participating Broker-Dealer, as
the case may be, shall have received (i) the copies of the supplemented or
amended Prospectus contemplated by Section 5(k) or (ii) the Advice.

6.   Registration Expenses
     ---------------------

          All reasonable fees and expenses incident to the performance of or
compliance with this Agreement by the Issuer shall be borne by the Issuer
whether or not the Exchange Offer or a Shelf Registration is filed or becomes
effective, including, without limitation, (i) all registration and filing fees
(including, without limitation, (A) fees with respect to filings required to be
made with the NASD in connection with an underwritten offering and (B) fees and
expenses of compliance with federal securities and state securities or Blue Sky
laws (including, without limitation, reasonable fees and disbursements of one
counsel in connection with Blue Sky qualifications of the Registrable Notes or
Exchange Notes and determination of the eligibility of the Registrable Notes or
Exchange Notes for investment under the laws of such jurisdictions (x) where the
holders of Registrable Notes are located, in the case of the Exchange Notes, or
(y) as provided in Section 5(h) hereof, in the case of Registrable Notes or
Exchange Notes to be sold by a Participating Broker-Dealer during the Applicable
Period)); (ii) printing expenses, including, without limitation, expenses of
printing certificates for Registrable Notes or Exchange Notes in a form eligible
for deposit with The Depository Trust Company; (iii) fees and disbursements of
all independent certified public accountants referred to in Section 5(m)(iii)
(including, without limitation, the expenses of any "cold comfort" letters
required by or incident to such performance); (iv) fees and expenses of all
other Persons retained by the Issuer (including fees and expenses of the
Trustee); (v) internal expenses of the Issuer (including, without limitation,
all salaries and expenses of officers and employees of the Issuer performing
legal or accounting duties); (vi) the expenses relating to printing, word
processing and distributing all Registration Statements, underwriting
agreements, securities sales agreements, indentures and any other documents
necessary in order to comply with this Agreement, but excluding any fees and
disbursements of underwriters, including, without limitation, underwriting
discounts, commissions and transfer taxes attributable to the sale of each
Registrable Note; (vii) any fees associated with making the Registrable Notes or
Exchange Notes eligible for trading through The Depository Trust Company; and
(viii) the reasonable expenses of Shulte Roth & Zabel LLP if retained by the
Required Holders, not to exceed $10,000 incurred in connection with reviewing
the Indenture under Section 2 (a).

7.   Indemnification
     ---------------

          (a)  The Issuer agrees to indemnify and hold harmless each Holder of
Registrable Notes and each Participating Broker-Dealer, the officers, directors,
employees and agents of each such Person, and each Person, if any, who controls
any such Person within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act (each, a "Participant"), from and against any and
                                         -----------
all losses, claims, damages and liabilities (including, without limitation, the
reasonable legal fees and other reasonable expenses actually incurred in
connection with investigating or defending any suit, action or proceeding or any
claim asserted) caused by, arising out of or based upon any untrue statement or
alleged untrue state-
<PAGE>

                                      -22-

ment of a material fact contained in any Registration Statement or Prospectus
(as amended or supplemented if the Issuer shall have furnished any amendments or
supplements thereto) or caused by, arising out of or based upon any omission or
alleged omission to state therein a 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, except insofar as such losses,
claims, damages or liabilities are caused by any untrue statement or omission or
alleged untrue statement or omission made in reliance upon and in conformity
with information relating to any Participant furnished to the Issuer in writing
by or on behalf of such Participant expressly for use therein; provided,
however, that the Issuer shall not be liable if such untrue statement or
omission or alleged untrue statement or omission was contained or made in any
preliminary prospectus and corrected in the Prospectus or any amendment or
supplement thereto and the Prospectus does not contain any other untrue
statement or omission or alleged untrue statement or omission of a material fact
that was the subject matter of the related proceeding and any such loss,
liability, claim, damage or expense suffered or incurred by the Participants
resulted from any action, claim or suit by any Person who purchased Registrable
Notes or Exchange Notes which are the subject thereof from such Participant and
it is established in the related proceeding that such Participant failed to
deliver or provide a copy of the Prospectus (as amended or supplemented) to such
Person with or prior to the confirmation of the sale of such Registrable Notes
or Exchange Notes sold to such Person if required by applicable law, unless such
failure to deliver or provide a copy of the Prospectus (as amended or
supplemented) was a result of noncompliance by the Issuer with Section 5 of this
Agreement.

          (b)  Each Participant will be required to agree, severally and not
jointly, to indemnify and hold harmless the Issuer, its directors and officers
and each Person who controls the Issuer within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Issuer to each Participant, but only with reference
to information relating to such Participant furnished to the Issuer in writing
by such Participant expressly for use in any Registration Statement or
Prospectus, any amendment or supplement thereto, or any preliminary prospectus.
The liability of any Participant under this paragraph shall in no event exceed
the proceeds received by such Participant from sales of Registrable Notes or
Exchange Notes giving rise to such obligations.

          (c)  If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any Person in respect of which indemnity may be sought pursuant to either of the
two preceding paragraphs, then such Person (the "Indemnified Person") shall
                                                 ------------------
promptly notify the Person against whom such indemnity may be sought (the
"Indemnifying Person") in writing, and the Indemnifying Person, upon request of
--------------------
the Indemnified Person, shall retain counsel reasonably satisfactory to the
Indemnified Person to represent the Indemnified Person and any others the
Indemnifying Person may reasonably designate in such proceeding and shall pay
the reasonable fees and ex-
<PAGE>

                                      -23-

penses actually incurred by such counsel related to such proceeding; provided,
however, that the failure to so notify the Indemnifying Person shall not relieve
it of any obligation or liability which it may have hereunder or otherwise. In
any such proceeding, any Indemnified Person 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 Person unless (i) the Indemnifying Person and the
Indemnified Person shall have mutually agreed in writing to the contrary; (ii)
the Indemnifying Person has failed within a reasonable time to retain counsel
reasonably satisfactory to the Indemnified Person; or (iii) the named parties in
any such proceeding (including any impleaded parties) include both the
Indemnifying Person and the Indemnified Person 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, unless there is a
conflict among Indemnified Persons, the Indemnifying Person shall not, in
connection with any proceeding or related proceeding in the same jurisdiction,
be liable for the fees and expenses of more than one separate firm (in addition
to any local counsel) for all Indemnified Persons and that all such fees and
expenses shall be reimbursed as they are incurred. Any such separate firm for
the Participants and such control Persons of Participants shall be designated in
writing by Participants who sold a majority in interest of Registrable Notes
sold by all such Participants and any such separate firm for the Issuer, its
directors, officers and such control Persons of the Issuer shall be designated
in writing by the Issuer. The Indemnifying Person shall not be liable for any
settlement of any proceeding effected without its written consent, but if
settled with such consent or if there is a final non-appealable judgment for the
plaintiff, the Indemnifying Person agrees to indemnify any Indemnified Person
from and against any loss or liability by reason of such settlement or judgment.
Notwithstanding the foregoing sentence, if at any time an Indemnified Person
shall have requested an Indemnifying Person to reimburse the Indemnified Person
for reasonable fees and expenses actually incurred by counsel as contemplated by
the third sentence of this paragraph, the Indemnifying Person agrees that it
shall be liable for any settlement of any proceeding effected without its
consent if (i) such settlement is entered into more than 30 days after receipt
by such Indemnifying Person of the aforesaid request and (ii) such Indemnifying
Person shall not have reimbursed the Indemnified Person in accordance with such
request prior to the date of such settlement; provided, however, that the
Indemnifying Person shall not be liable for any settlement effected without its
consent pursuant to this sentence if the Indemnifying Person is contesting, in
good faith, the request for reimbursement. No Indemnifying Person shall, without
the prior written consent of the Indemnified Person, effect any settlement of
any pending or threatened proceeding in respect of which any Indemnified Person
is or could have been a party and indemnity could have been sought hereunder by
such Indemnified Person, unless such settlement (A) includes an unconditional
release of such Indemnified Person, in form and substance satisfactory to such
Indemnified Person, from all liability on claims that are the subject matter of
such proceeding and (B) does not include any statement as to an admission of
fault, culpability or failure to act by or on behalf of an Indemnified Person.
<PAGE>

                                      -24-

          (d)  If the indemnification provided for in the first and second
paragraphs of this Section 7 is legally unavailable to, and accordingly
insufficient to hold harmless, an Indemnified Person in respect of any losses,
claims, damages or liabilities referred to therein, then each Indemnifying
Person under such paragraphs, in lieu of indemnifying such Indemnified Person
thereunder and in order to provide for just and equitable contribution, shall
contribute to the amount paid or payable by such Indemnified Person as a result
of such losses, claims, damages or liabilities in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Person or Persons
on the one hand and the Indemnified Person or Persons on the other in connection
with the statements or omissions (or alleged statements or omissions) that
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof) as well as any other relevant equitable considerations.  The relative
fault of the parties shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Issuer on the one hand or by the Participants or such other
Indemnified Person, as the case may be, on the other, the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission and any other equitable considerations appropriate
under the circumstances.

          (e)  The parties agree that it would not be just and equitable if
contribution pursuant to this Section 7 were determined by pro rata allocation
(even if the Participants were treated as one entity for such purpose) or by any
other method of allocation that does not take account of the equitable
considerations referred to in the immediately preceding paragraph.  The amount
paid or payable by an Indemnified Person as a result of the losses, claims,
damages and liabilities referred to in the immediately preceding paragraph shall
be deemed to include, subject to the limitations set forth above, any reasonable
legal or other expenses actually incurred by such Indemnified Person in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 7, in no event shall a
Participant be required to contribute any amount in excess of the amount by
which proceeds received by such Participant from sales of Registrable Notes or
Exchange Notes, as the case may be, exceeds the amount of any damages that such
Participant 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.

          (f)  The indemnity and contribution agreements contained in this
Section 7 will be in addition to any liability which the Indemnifying Persons
may otherwise have to the Indemnified Persons referred to above.

8.   Underwritten Registrations
     --------------------------

          If any of the Registrable Notes covered by any Shelf Registration are
to be sold in an underwritten offering, then the investment banker or investment
bankers and manager or managers that will manage the offering will be selected
by the Holders of a majority in aggregate principal amount at maturity of such
Registrable Notes included in such offering and reasonably acceptable to the
Issuer; provided, however, that the Issuer shall be entitled to select one co-
lead manager to administer such offering, which co-lead manager shall be
reasonably acceptable to the Holders of a majority in aggregate principal amount
at maturity of such Registrable Notes included in such offering.

          No Holder of Registrable Notes may participate in any underwritten
registration hereunder unless such Holder (a) agrees to sell such Holder's
Registrable Notes on the basis provided in any underwriting arrangements
approved by the Persons entitled hereunder to approve such arrangements and (b)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents required under the terms of such
underwriting arrangements.

9.   Miscellaneous
     -------------

          (a)  Remedies. Except as otherwise specifically provided herein, in
               --------
the event of a breach by the Issuer of any of its obligations under this
Agreement, each Holder of Registrable Notes and each Participating Broker-Dealer
holding Exchange Notes, in addition to being entitled to exercise all rights
provided herein, in the Indenture or, in the case of a Purchaser, in the
Purchase Agreement, or granted by law, including recovery of damages, will be
entitled to specific performance of its rights under this Agreement.  Except as
otherwise specifically provided herein, the Issuer agrees that monetary damages
would not be adequate compensation for any loss incurred by reason of a breach
by it of any of the provisions of this Agreement and hereby further agrees that,
in the event of any action for specific performance in respect of such breach,
it shall waive the defense that a remedy at law would be adequate.

          (b)  No Inconsistent Agreements. The Issuer has not entered into, as
               --------------------------
of the date hereof, and shall not enter into, after the date of this Agreement,
any agreement with respect to any of its securities that is inconsistent with
the rights granted to the Holders of Registrable Notes in this Agreement or
otherwise conflicts with the provisions hereof. The Issuer has not entered into
and shall not enter into any agreement with respect to any of the Issuer's
securities which will grant to any Person piggy-back rights with respect to a
Registration Statement.

          (c)  Amendments and Waivers. The provisions of this Agreement may not
               ----------------------
be amended, modified or supplemented, and waivers or consents to departures from
the provi-
<PAGE>

                                      -26-

sions hereof may not be given, otherwise than with the prior written consent of
(i) the Holders of not less than a majority in aggregate principal amount at
maturity of the then outstanding Registrable Notes and (ii) in circumstances
that would adversely affect Participating Broker-Dealers, the Participating
Broker-Dealers holding not less than a majority in aggregate principal amount at
maturity of the Exchange Notes held by all Participating Broker-Dealers;
provided, however, that Section 7 and this Section 10(c) may not be amended,
modified or supplemented without the prior written consent of each Holder and
each Participating Broker-Dealer (including any Person who was a Holder or
Participating Broker-Dealer of Registrable Notes or Exchange Notes, as the case
may be, disposed of pursuant to any Registration Statement). 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
Notes whose securities are being tendered pursuant to the Exchange Offer or sold
pursuant to a Registration Statement and that does not directly or indirectly
affect, impair, limit or compromise the rights of other Holders of Registrable
Notes may be given by Holders of at least a majority in aggregate principal
amount at maturity of the Registrable Notes being tendered or being sold by such
Holders pursuant to such Registration Statement.

          (d)  Notices. All notices and other communications provided for or
               -------
permitted hereunder shall be made in writing by hand-delivery, registered first-
class mail, next-day air courier or telecopier:

          (i)  if to a Holder of Registrable Notes, at the most current address
     of such Holder set forth on the records of the Issuer or the registrar
     under the Indenture, as the case may be; and

          (ii) if to the Issuer at 5667 Gibraltar Drive, Pleasanton, CA 94588,
     attention: Bernard Schneider, or at such other address as the Issuer shall
     have specified to each Holder in writing with a copy to Cahill Gordon &
     Reindel, 80 Pine Street, New York, NY 10005, attention: Jonathan A.
     Schaffzin, Esq.

          All such notices and communications shall be deemed to have been duly
given:  when delivered by hand, if personally delivered; five business days
after being deposited in the mail, postage prepaid, if mailed; one business day
after being timely delivered to a next-day air courier guaranteeing overnight
delivery; and when receipt is acknowledged by the addressee, if telecopied.
