holder of Transfer Restricted Notes (each, a "Holder") whenever such Person owns

SECTION 3. REGISTERED EXCHANGE OFFER

         (a) Unless the Exchange Offer shall not be permissible under applicable
law or Commission policy (after the procedures set forth in Section 6(a) below
have been complied with), the Company shall (i) cause to be filed with the
Commission as soon as practicable after the Closing Date, but in no event later
than 90 days after the Closing Date, a Registration Statement under the Act
relating to the Series B Notes and the




                                       4
<PAGE>   5

Exchange Offer, (ii) use its best efforts to cause such Registration Statement
to become effective at the earliest possible time, but in no event later than
180 days after the Closing Date, (iii) in connection with the foregoing, file
(A) all pre-effective amendments to such Registration Statement as may be
necessary in order to cause such Registration Statement to become effective, (B)
if applicable a post-effective amendment to such Registration Statement pursuant
to Rule 430A under the Act and (C) cause all necessary filings in connection
with the registration and qualification of the Series B Notes to be made under
the Blue Sky laws of such jurisdictions as are necessary to permit Consummation
of the Exchange Offer, and (iv) upon the effectiveness of such Registration
Statement, commence the Exchange Offer. The Exchange Offer shall be on the
appropriate form permitting registration of the Series B Notes to be offered in
exchange for the Transfer Restricted Notes and to permit resales of Notes held
by Broker-Dealers as contemplated by Section 3(c) below.

         (b) The Company shall cause the Exchange Offer Registration Statement
to be effective continuously and shall keep the Exchange Offer open for a period
of not less than the minimum period required under applicable federal and state
securities laws to Consummate the Exchange Offer; provided, however, that in no
event shall such period be less than 20 business days. The Company shall cause
the Exchange Offer to comply with all applicable federal and state securities
laws. No securities other than the Notes shall be included in the Exchange Offer
Registration Statement. The Company shall use its best efforts to cause the
Exchange Offer to be Consummated on the earliest practicable date after the
Exchange Offer Registration Statement has become effective and not later than 30
business days thereafter.

         (c) The Company shall indicate in a "Plan of Distribution" section
contained in the Prospectus contained in the Exchange Offer Registration
Statement that any Broker-Dealer who holds Series C Notes that are Transfer
Restricted Notes and that were acquired for its own account as a result of
market-making activities or other trading activities (other than Transfer
Restricted Notes acquired directly from the Company) may exchange such Series C
Notes pursuant to the Exchange Offer; however, such Broker-Dealer may be deemed
to be an "underwriter" within the meaning of the Act and must, therefore,
deliver a prospectus meeting the requirements of the Act in connection with any
resales of the Series B Notes received by such Broker-Dealer in the Exchange
Offer, which prospectus delivery requirement may be satisfied by the delivery by
such Broker-Dealer of the Prospectus contained in the Exchange Offer
Registration Statement. Such "Plan of Distribution" section shall also contain
all other material information with respect to such resales by Broker-Dealers
that the Commission may require in order to permit such resales pursuant
thereto, but such "Plan of Distribution" shall not name any such Broker-Dealer
or disclose the amount of Notes held by any such Broker-Dealer except to the
extent required by the Commission as a result of a change in policy after the
date of this Agreement.

         The Company shall use its best efforts to keep the Exchange Offer
Registration Statement continuously effective, supplemented and amended as
required by the provisions of Section 6(c) below to the extent necessary to
ensure that it is available for 




                                       5
<PAGE>   6

resales of Notes acquired by Broker-Dealers for their own accounts as a result
of market-making activities or other trading activities, and to ensure that it
conforms with the requirements of this Agreement, the Act and the policies,
rules and regulations of the Commission as announced from time to time, for a
period of 180 days from the date on which the Exchange Offer Registration
Statement is declared effective.

         The Company shall provide sufficient copies of the latest version of
such Prospectus to Broker-Dealers promptly upon request at any time during such
one-year period in order to facilitate such resales.

SECTION 4. SHELF REGISTRATION

         (a) Shelf Registration. If (i) the Exchange Offer is not available to
any Holder or may not be consummated because, in either case, it would violate
applicable securities laws or because the applicable interpretations of the
staff of the Commission would not permit the Company to effect the Exchange
Offer (after the procedures set forth in Section 6(a) below have been complied
with) or (ii) the Company has not Consummated the Exchange Offer within 210 days
of the Closing Date, then the Company shall use its reasonable best efforts to:

                           (x) cause to be filed a shelf registration statement
                  pursuant to Rule 415 under the Act, which may be an amendment
                  to the Exchange Offer Registration Statement (in either event,
                  the "Shelf Registration Statement") on or prior to the earlier
                  to occur of (1) the 60th day after the date on which the
                  Company determines that it is not required to file the
                  Exchange Offer Registration Statement or to consummate the
                  Exchange Offer and (2) the 240th day after the Closing Date
                  (such earliest date being the "Shelf Filing Deadline"), which
                  Shelf Registration Statement shall provide for resales of all
                  Transfer Restricted Notes the Holders of which shall have
                  provided the information required pursuant to Section 4(b)
                  hereof; and

                           (y) cause such Shelf Registration Statement to be
                  declared effective by the Commission on or before the 75th day
                  after the Shelf Filing Deadline.

The Company shall use its best efforts to keep such Shelf Registration Statement
continuously effective, supplemented and amended as required by the provisions
of Sections 6(b) and (c) hereof to the extent necessary to ensure that it is
available for resales of Notes by the Holders of Transfer Restricted Notes
entitled to the benefit of this Section 4(a), and to ensure that it conforms
with the requirements of this Agreement, the Act and the policies, rules and
regulations of the Commission as announced from time to time, for a period of at
least two years following the Closing Date.

         (b) Provision by Holders of Certain Information in Connection with the
Shelf Registration Statement. No Holder of Transfer Restricted Notes may include
any of its Transfer Restricted Notes in any Shelf Registration Statement
pursuant to this Agreement




                                       6
<PAGE>   7

unless and until such Holder furnishes to the Company in writing, within 20
business days after receipt of a request therefor, such information as the
Company may reasonably request for use in connection with any Shelf Registration
Statement or Prospectus or preliminary Prospectus included therein. No Holder of
Transfer Restricted Notes shall be entitled to Liquidated Damages pursuant to
Section 5 hereof unless and until such Holder shall have used its best efforts
to provide all such reasonably requested information. Each Holder as to which
any Shelf Registration Statement is being effected agrees to furnish promptly to
the Company all information required to be disclosed in order to make the
information previously furnished to the Company by such Holder not materially
misleading.

SECTION 5. LIQUIDATED DAMAGES

         If (i) any of the Registration Statements required by this Agreement is
not filed with the Commission on or prior to the date specified for such filing
in this Agreement, (ii) any of such Registration Statements has not been
declared effective by the Commission on or prior to the date specified for such
effectiveness in this Agreement (the "Effectiveness Target Date"), (iii) the
Exchange Offer has not been Consummated within 30 business days after the
Effectiveness Target Date with respect to the Exchange Offer Registration
Statement (assuming that the Company is required pursuant to Section 3 of this
Agreement to file the Exchange Offer Registration Statement and to consummate
the Exchange Offer) or (iv) any Registration Statement required by this
Agreement is filed and declared effective but shall thereafter cease to be
effective or fail to be usable for its intended purpose (during the period that
such Registration Statement is required to be kept effective or usable for its
intended purpose) without being succeeded immediately by a post-effective to
such Registration Statement that causes such failure and that is itself
immediately declared effective (each such event referred to in clauses (i)
through (iv), a "Registration Default"), the Company hereby agrees to pay
liquidated damages to each Holder of Transfer Restricted Notes affected by such
Registration Default on each Interest Payment Date accruing from and after the
date of each Registration Default, and shall continue to accrue thereafter until
such Registration Default has been cured or waived, at a rate equal to 0.25% per
annum of the principal amount of Notes during the first 90-day period
immediately following the occurrence of such Registration Default, which rate
shall increase by an additional 0.25% per annum on the first day of each
subsequent 90-day period up to a maximum rate equal to 1.0% per annum. All
accrued liquidated damages shall be paid to Record Holders by the Company in the
manner provided in the Indenture. Following the cure of all Registration
Defaults relating to any particular Transfer Restricted Notes, the accrual of
liquidated damages with respect to such Transfer Restricted Notes will cease.

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

SECTION 6. REGISTRATION PROCEDURES

         (a) Exchange Offer Registration Statement. In connection with the
Exchange Offer, the Company shall comply with all of the provisions of Section
6(c) below, shall use its best efforts to effect such exchange to permit the
sale of Transfer Restricted Notes being sold in accordance with the intended
method or methods of distribution thereof, and shall comply with all of the
following provisions:

                           (i) If in the reasonable opinion of counsel to the
                  Company there is a significant question as to whether the
                  Exchange Offer is permitted by applicable law, the Company
                  hereby agrees to seek a no-action letter or other favorable
                  decision from the Commission allowing the Company to
                  Consummate an Exchange Offer for such Series C Notes. The
                  Company hereby agrees to pursue the issuance of such a
                  decision to the Commission staff level but shall not be
                  required to take commercially unreasonable action to effect a
                  change of Commission policy. The Company hereby agrees,
                  however, to (A) participate in telephonic conferences with the
                  Commission, (B) deliver to the Commission staff an analysis
                  prepared by counsel to the Company setting forth the legal
                  bases, if any, upon which such counsel has concluded that such
                  an Exchange Offer should be permitted and (C) diligently
                  pursue a resolution (which need not be favorable) by the
                  Commission staff of such submission.

                           (ii) As a condition to its participation in the
                  Exchange Offer pursuant to the terms of this Agreement, each
                  Holder of Transfer Restricted Notes shall furnish, upon the
                  request of the Company, prior to the Consummation thereof, a
                  written representation to the Company (which may be contained
                  in the letter of transmittal contemplated by the Exchange
                  Offer Registration Statement) to the effect that (A) it is not
                  an affiliate of the Company, (B) it is not engaged in, and
                  does not intend to engage in, and has no arrangement or
                  understanding with any Person to participate in, a
                  distribution of the Series B Notes to be issued in the
                  Exchange Offer and (C) it is acquiring the Series B Notes in
                  its ordinary course of business. In addition, all such Holders
                  of Transfer Restricted Notes shall otherwise cooperate in the
                  Company's preparations for the Exchange Offer. Each Holder
                  will be required to acknowledge and agree (as set forth in the
                  letter of transmittal contemplated by the Exchange Offer
                  Registration Statement) that, if it is a Broker-Dealer or if
                  such Holder intends to use the Exchange Offer to participate
                  in a distribution of the securities to be acquired in the
                  Exchange Offer, such Holder (1) could not under Commission
                  policy as in effect on the date of this Agreement rely on the
                  position of the Commission enunciated in Morgan Stanley and
                  Co., Inc. (available June 5, 1991) and Exxon Capital Holdings
                  Corporation (available May 13, 1988), as interpreted in the
                  Commission's letter to Shearman & Sterling dated July 2, 1993,
                  and similar no-action letters (including any no-action letter
                  obtained pursuant to clause (i) above), and 




                                       8
<PAGE>   9

                  (2) must comply with the registration and prospectus delivery
                  requirements of the Act in connection with a secondary resale
                  transaction and that such a secondary resale transaction
                  should be covered by an effective registration statement
                  containing the selling security holder information required by
                  Item 507 or 508, as applicable, of Regulation S-K, if the
                  resales are of Series B Notes obtained by such Holder in
                  exchange for Series C Notes acquired by such Holder directly
                  from the Company.

                           (iii) Prior to effectiveness of the Exchange Offer
                  Registration Statement, the Company shall, if requested by the
                  Commission, provide a supplemental letter to the Commission
                  (A) stating that the Company is registering the Exchange Offer
                  in reliance on the position of the Commission enunciated in
                  Exxon Capital Holdings Corporation (available May 13, 1988),
                  Morgan Stanley and Co., Inc. (available June 5, 1991) and, if
                  applicable, any no-action letter obtained pursuant to clause
                  (i) above and (B) including a representation that the Company
                  has not entered into any arrangement or understanding with any
                  Person to distribute the Series B Notes to be received in the
                  Exchange Offer and that, to the best of the Company's
                  information and belief, each Holder participating in the
                  Exchange Offer is acquiring the Series B Notes in its ordinary
                  course of business and has no arrangement or understanding
                  with any Person to participate in the distribution of the
                  Series B Notes received in the Exchange Offer.

         (b) Shelf Registration Statement. In connection with the Shelf
Registration Statement, the Company shall comply with all the provisions of
Section 6(c) below and shall use its best efforts to effect such registration to
permit the sale of the Transfer Restricted Notes being sold in accordance with
the intended method or methods of distribution thereof and, pursuant thereto,
the Company will as expeditiously as possible prepare and file with the
Commission a Registration Statement relating to the registration on any
appropriate form under the Act, which form shall be available for the sale of
the Transfer Restricted Notes in accordance with the intended method or methods
of distribution thereof.

         (c) General Provisions. In connection with any Registration Statement
and any Prospectus required by this Agreement to permit the sale or resale of
Transfer Restricted Notes (including, without limitation, any Registration
Statement and the related Prospectus required to permit resales of Notes by
Broker-Dealers) the Company shall:

                           (i) use its best efforts to keep such Registration
                  Statement continuously effective and provide all requisite
                  financial statements for the period specified in Section 3 or
                  4 of this Agreement, as applicable; upon the occurrence of any
                  event that would cause any such Registration Statement or the
                  Prospectus contained therein (A) to contain a material
                  misstatement or omission or (B) not to be effective and usable
                  for resale of Transfer Restricted Notes during the period
                  required by this Agreement, 




                                       9
<PAGE>   10

                  Holders of Notes to effect such changes to the Indenture as
                  may be required for such Indenture to be so qualified in
                  accordance with the terms of the TIA; and execute and use its
                  best efforts to cause the Trustee to execute, all documents
                  that may be required to effect such changes and all other
                  forms and documents required to be filed with the Commission
                  to enable such Indenture to be so qualified in a timely
                  manner;

                           (xxi) use its best efforts to cause all Transfer
                  Restricted Notes covered by the Registration Statement to be
                  listed on each securities exchange on which similar securities
                  issued by the Company are then listed if requested by the
                  Holders of a majority in aggregate principal amount of Series
                  C Notes or the managing underwriter(s), if any; and

                           (xxii) provide promptly to each Holder upon request
                  each document filed with the Commission pursuant to the
                  requirements of Section 13 and Section 15 of the Exchange Act.

         Each Holder agrees by acquisition of a Transfer Restricted Note that,
upon receipt of any notice from the Company of the existence of any fact of the
kind described in Section 6(c)(iii)(D) hereof, such Holder will forthwith
discontinue disposition of Transfer Restricted Notes pursuant to the applicable
Registration Statement until such Holder's receipt of the copies of the
supplemented or amended Prospectus contemplated by Section 6(c)(xvi) hereof, or
until it is advised in writing (the "Advice") by the Company that the use of the
Prospectus may be resumed, and has received copies of any additional or
supplemental filings that are incorporated by reference in this Prospectus. If
so desired by the Company, each Holder will deliver to the Company (at the
Company's expense) all copies, other than permanent file copies then in such
Holder's possession, of the Prospectus covering such Transfer Restricted Notes
that was current at the time of receipt of such notice. In the event the Company
shall give any such notice, the time period regarding the effectiveness of such
Registration Statement set forth in Section 3 or 4 hereof, as applicable, shall
be extended by the number of days during the period from the date of such notice
to the date when each selling Holder covered by such Registration Statement
shall have received the copies of the supplemented or amended Prospectus
contemplated by Section (6)(c)(xvi) hereof or shall have received the Advice.

         (a) All expenses incident to the Company's performance of or compliance

Holders of a majority in principal amount of the Transfer Restricted Notes for
whose benefit such Registration Statement is being prepared. Such Holders shall
be responsible for any and all other out-of-pocket expenses of the Holders of
Transfer Restricted Notes incurred in connection with the registration of the
Transfer Restricted Notes of such Holders.

SECTION 8. INDEMNIFICATION

         (a) The Company agrees to indemnify and hold harmless (i) each Holder,
(ii) each person, if any, who controls any Holder within the meaning of Section
15 of the Act or Section 20(a) of the Exchange Act and (iii) the respective
officers, directors, partners and employees of any Holder or any controlling
person (any person referred to in clauses (i), (ii) or (iii) may hereinafter be
referred to as an "indemnified Holder"), to the fullest extent lawful, from and
against any and all losses, liabilities, claims, damages and expenses whatsoever
(including but not limited to reasonable attorneys' fees and any and all
expenses whatsoever reasonably incurred in investigating, preparing or defending
against any investigation or litigation, commended or threatened, or any claim
whatsoever, and any and all amounts paid in settlement of any claim or
litigation), joint or several, to which they or any of them may become subject
under the Act, the Exchange Act or otherwise, insofar as such losses,
liabilities, claims damages or expenses (or actions in respect thereof) arise
out of or are based upon any untrue statement or alleged untrue statement of




                                       16
<PAGE>   17

a material fact contained in any Registration Statement or Prospectus, or in any
supplement thereto or amendment thereof, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading; provided, however,
that the Company will not be liable in any such case to the extent, but only to
the extent, that any such loss, liability, claim, damage or expense arises out
of or is based upon any such untrue statement or alleged untrue statement or
omission made therein upon and in conformity with written information furnished
to the Company by or on behalf of any of the Holders expressly for use therein.
This indemnity agreement will be in addition to any liability which the Company
may otherwise have, including under this Agreement.

         (b) Each Holder of Transfer Restricted Notes agrees, severally and not
jointly, to indemnify and hold harmless the Company, and each person, if any,
who controls the Company within the meaning of Section 15 of the Act or Section
20(a) of the Exchange Act to the same extent as the foregoing indemnity from the
Company to each of the Indemnified Holders, but only with respect to information
relating to such Holder furnished in writing by such Holder for use in any
Registration Statement, or in any amendment thereof or supplement thereto:
provided, however, that in no case shall any selling Holder be liable or
responsible for any amount in excess of proceeds received by such Holder upon
the sale of the Registrable Securities giving rise to such indemnification
obligation. This indemnity will be in addition to any liability which the Holder
may otherwise have, including under this Agreement.

         (c) Promptly after receipt by an indemnified party under subsection (a)
or (b) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under such subsection, notify each party against whom indemnification is
to be sought in writing of the commencement thereof (but the failure so to
notify an indemnifying party shall not relieve it from any liability which it
may have under this Section 6 or otherwise except to the extent that it has been
prejudiced in any material respect by such failure). In case any such action is
brought against any indemnified party, and it notified an indemnifying party of
the commencement thereof, the indemnifying party will be entitled to participate
therein, and to the extent it may elect by written notice delivered to the
indemnified party promptly after receiving the aforesaid notice from such
indemnified party to assume the defense thereof with counsel reasonably
satisfactory to such indemnified party. Notwithstanding the foregoing, the
indemnified party or parties shall have the right to employ its or their own
counsel in any such case, but the fees and expenses of such counsel shall be at
the expense of such indemnified party or parties unless (i) the employment of
such counsel shall have been authorized in writing by the indemnifying parties
in connection with the defense of such action, (ii) the indemnifying parties
shall not have employed counsel to take charge of the defense of such action
within a reasonable time after notice of commencement of the action, or (iii)
such indemnified party or parties shall have been advised by counsel that there
may be legal defenses available to it or them which are different from or
additional to those available to the indemnifying parties (in which case the
indemnifying party or parties shall not have the right to direct the defense




                                       17
<PAGE>   18

of such action on behalf of the indemnified party or parties), in any of which
events such fees and expenses of counsel shall be borne by the indemnifying
parties; provided, however, that the indemnifying party under subsection (a) or
(b) above shall only be liable for the legal expenses of one counsel (in
addition to any local counsel) for all indemnified parties in each jurisdiction
in which any claim or action is brought. Anything in this subsection to the
contrary notwithstanding, an indemnifying party shall not be liable for any
settlement of any claim or action effected without its prior written consent;
provided that such consent was not unreasonably withheld.

SECTION 9. CONTRIBUTION

         In order to provide for contribution in circumstances in which the
indemnification provided for in Section 8 is for any reason held to be
unavailable from the Company or is insufficient to hold harmless a party
indemnified thereunder, the Company, on the one hand, and the Holders on the
other hand, shall contribute to the aggregate losses, claims, damages,
liabilities and expenses of the nature contemplated by such indemnification
provision (including any investigation, legal and other expenses reasonably
incurred in connection with, and any amount paid in settlement of, any action,
suit or proceeding or any claims asserted, but after the deducting in the case
of losses, claims, damages, liabilities and expenses suffered by the Company,
any contribution received by the Company from persons, other than a Holder, who
may also be liable for contribution, including persons who control the Company
within the meaning of Section 15 of the Act or Section 20(a) of the Exchange
Act) to which the Company, or any Holder may be subject, in such proportion as
is appropriate to reflect the relative benefits received by the Company, on one
hand, and each Holder, on the other hand, from the offering of the Series C
Notes or, if such allocation is not permitted by applicable law or
indemnification is not available as a result of the indemnifying party not
having received notice as provided in Section 8, in such proportion as is
appropriate to reflect not only the relative benefits referred to above but also
the relative fault of the Company, on one hand, and the Holders on the other
hand, in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations. The relative benefits received by the Company, on one
hand, and the Holders, on the other hand, shall be deemed to be in the same
proportion as (i) the total proceeds from the offering of Series C Notes (net of
discounts but before deducting expenses) received by the Company and (ii) the
discounts and commissions received by the Initial Purchaser respectively. The
relative fault of the Company, on one hand, and of each Holder, on the other
hand, shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
or such Holder and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and each Holder of Transfer Restricted Notes agree that it would not
be just and equitable if contribution pursuant to this Section 9 were determined
by pro rata allocation or by any other method of allocation which does not take
into account the equitable considerations referred to above. Notwithstanding the
provisions of this Section 9, (i) in no case shall any Holder be required to
contribute any amount in excess of the amount by which the 




                                       18
<PAGE>   19

proceeds received by such Holder upon the sale of the Transfer Restricted Notes
giving rise to such obligation exceeds the amount of any damages which such
Holder has otherwise been required to pay by reason of any untrue or alleged
untrue statement or omission or alleged omission and (ii) no person guilty of
fraudulent misrepresentation (with the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentations. For purposes of this Section 7, (A) each person,
if any, who controls the Initial Purchaser within the meaning of Section 15 of
the Act or Section 20(a) of the Exchange Act and (B) the respective officers,
directors, partners, employees, representatives and agents of such Holder or any
controlling persons shall have the same rights to contribution as the Initial
Purchaser, and each person, if any, who controls the Company within the meaning
of Section 15 of the Act or Section 20(a) of the Exchange Act shall have the
same rights to contribution as the Company, subject in each case to clauses (i)
and (ii) of this Section 9. Any party entitled to contribution will, promptly
after receipt of notice of commencement of any action, suit or proceeding
against such party in respect of which a claim for contribution may be made
against another party or parties under this Section 9, notify such party or
parties from whom contribution may be sought, but the failure to so notify such
party or parties shall not relieve the party or parties from whom contribution
may be sought from any obligation it or they may have under this Section 9 or
otherwise. No party shall be liable for contribution with respect to any action
or claim settled without its prior written consent; provided that such written
consent was not unreasonably withheld.

SECTION 10. RULE 144A

         The Company hereby agrees with each Holder, for so long as any Transfer
Restricted Notes remain outstanding and during any period in which the Company
is not subject to Section 13 or 15(d) of the Securities Exchange Act of 1934, as
amended, to make available to any Holder or beneficial owner of Transfer
Restricted Notes in connection with any sale thereof and any prospective
purchaser of such Transfer Restricted Notes from such Holder or beneficial
owner, in each case upon request, the information required by Rule 144A(d)(4)
under the Act in order to permit resales of such Transfer Restricted Notes
pursuant to Rule 144A.

SECTION 11. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS

         No Holder may participate in any Underwritten Registration hereunder
unless such Holder (a) agrees to sell such Holder's Transfer Restricted 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 reasonable questionnaires, powers of attorney, indemnities, underwriting
agreements, lock-up letters and other documents required under the terms of such
underwriting arrangements.

SECTION 12. SELECTION OF UNDERWRITERS

         The Holders of Transfer Restricted Notes covered by the Shelf
Registration Statement who desire to do so may sell such Transfer Restricted
Notes in an Underwritten




                                       19
<PAGE>   20

Offering. In any such Underwritten Offering, the investment banker or investment
bankers and manager or managers that will administer the offering will be
selected by the Holders of a majority in aggregate principal amount of the
Transfer Restricted Notes included in such offering; provided that such
investment bankers and managers must be reasonably satisfactory to the Company.

SECTION 13. MISCELLANEOUS

         (a) Remedies. The Company agrees that monetary damages (including the
liquidated damages contemplated thereby) would not be adequate compensation for
any loss incurred by reason of a breach by it of the provisions of this
Agreement and hereby agrees to waive the defense in any action for specific
performance that a remedy at law would be adequate.

         (b) No Inconsistent Agreements. The Company shall not, on or after the
date of this Agreement, enter into any agreement with respect to its securities
that is inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. The rights granted to the
Holders hereunder do not in any way conflict with and are not inconsistent with
the rights granted to the holders of the Company's securities under any
agreement in effect on the date hereof.

         (c) Adjustments Affecting the Notes. The Company shall not take any
action, or permit any change to occur, with respect to the Notes that would
materially and adversely affect the ability of the Holders to consummate any
Exchange Offer.

         (d) Amendments and Waivers. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to or departures from
the provisions hereby may not be given unless the Company has obtained the
written consent of Holders of a majority of the outstanding principal amount of
Transfer Restricted Notes. Notwithstanding the foregoing, a waiver or consent to
departure from the provisions hereof the relates exclusively to the rights of
Holders whose securities are being tendered pursuant to the Exchange Offer and
that does not affect directly or indirectly the rights of other Holders whose
securities are not being tendered pursuant to such Exchange Offer may be given
by the Holders of a majority of the outstanding principal amount of Transfer
Restricted Notes being tendered or registered.

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