<PAGE>

Exchange Offer. The Company shall commence the Exchange Offer promptly after the

         will be accepted for exchange;

(ii)     the dates of acceptance for exchange (which shall be a period of at
         least 20 Business Days from the date such notice is mailed) (the
         "Exchange Dates");

(iii)    that any Registrable Note not tendered will remain outstanding and
         continue to accrue interest but will not retain any rights under this
         Agreement;

(iv)     that any Holder electing to have a Registrable Note exchanged pursuant
         to the Exchange Offer will be required to surrender such Registrable
         Note, together with the appropriate letters of transmittal, to the
         institution and at the address (located in the Borough of Manhattan,
         The City of New York) and in the manner specified in the notice, prior
         to the close of business on the last Exchange Date; and

(v)      that any Holder will be entitled to withdraw its election, not later
         than the close of business on the last Exchange Date, by sending to the
         institution and at the address (located in the Borough of Manhattan,
         The City of New York) specified in the notice, a telegram, telex,
         facsimile transmission or letter setting forth the name of such Holder,
         the principal amount of Registrable Notes delivered for exchange and a
         statement that such Holder is withdrawing its election to have such
         Notes exchanged.

         As a condition to participating in the Exchange Offer, a Holder will be
required to represent to the Company that (i) any Exchange Notes to be received
by it will be acquired in the ordinary course of its business, (ii) at the time
of the commencement of the Exchange Offer it has no arrangement or understanding
with any Person to participate in the distribution (within the meaning of the
Securities Act) of the Exchange Notes in violation of the provisions of the
Securities Act, (iii) it is not an "affiliate" (within the meaning of Rule 405
under Securities Act) of the Company and (iv) if such Holder is a broker-dealer
that will receive Exchange Notes for its own account in exchange for Registrable
Notes that were acquired as a result of market-making or other trading
activities, then such Holder will deliver a Prospectus in connection with any
resale of such Exchange Notes.

         As soon as practicable after the last Exchange Date, the Company shall:

(i)      accept for exchange Registrable Notes or portions thereof validly
         tendered and not properly withdrawn pursuant to the Exchange Offer; and

(ii)     deliver, or cause to be delivered, to the Trustee for cancellation all
         Registrable Notes or portions thereof so accepted for exchange by the
         Company and issue, and cause the Trustee to promptly authenticate and
         deliver to each Holder, Exchange Notes equal in

                                       4
<PAGE>

         principal amount to the principal amount of the Registrable Notes
         surrendered by such Holder.

         The Company shall use its reasonable best efforts to complete the
Exchange Offer as provided above and shall comply with the applicable
requirements of the Securities Act, the Exchange Act and other applicable laws
and regulations in connection with the Exchange Offer. The Exchange Offer shall
not be subject to any conditions, other than that the Exchange Offer does not
violate any applicable law or applicable interpretations of the Staff of the
SEC.

         (b) In the event that (i) the Company determines that the Exchange
Offer Registration provided for in Section 2(a) above is not available or may
not be completed as soon as practicable after the last Exchange Date because it
would violate any applicable law or applicable interpretations of the Staff of
the SEC, (ii) the Exchange Offer is not for any other reason completed by
September 12, 2002 or (iii) the Exchange Offer has been completed and in the
opinion of counsel for the Initial Purchasers a Registration Statement must be
filed and a Prospectus must be delivered by the Initial Purchasers in connection
with any offering or sale of Registrable Notes, the Company shall use its
reasonable best efforts to cause to be filed as soon as practicable after such
determination, date or notice of such opinion of counsel is given to the
Company, as the case may be, a Shelf Registration Statement providing for the
sale of all the Registrable Notes by the Holders thereof and to have such Shelf
Registration Statement declared effective by the SEC.

         In the event that the Company is required to file a Shelf Registration
Statement solely as a result of the matters referred to in clause (iii) of the
preceding sentence, the Company shall use its reasonable best efforts to file
and have declared effective by the SEC both an Exchange Offer Registration
Statement pursuant to Section 2(a) with respect to all Registrable Notes and a
Shelf Registration Statement (which may be a combined Registration Statement
with the Exchange Offer Registration Statement) with respect to offers and sales
of Registrable Notes held by the Initial Purchasers after completion of the
Exchange Offer.

         The Company agrees to use its reasonable best efforts to keep the Shelf
Registration Statement continuously effective until the expiration of the period
referred to in Rule 144(k) under the Securities Act with respect to the
Registrable Notes or such shorter period that will terminate when all the
Registrable Notes covered by the Shelf Registration Statement have been sold
pursuant to the Shelf Registration Statement. The Company further agrees to
supplement or amend the Shelf Registration Statement and the related Prospectus
if required by the rules, regulations or instructions applicable to the
registration form used by the Company for such Shelf Registration Statement or
by the Securities Act or by any other rules and regulations thereunder for shelf
registration or if reasonably requested by a Holder of Registrable Notes with
respect to information relating to such Holder, and to use its reasonable best
efforts to cause any such amendment to become effective and such Shelf
Registration Statement and Prospectus to become usable as soon as thereafter
practicable. The Company agrees to furnish to the Holders of Registrable Notes
copies of any such supplement or amendment promptly after its being used or
filed with the SEC.

         (c) The Company shall pay all Registration Expenses in connection with
the registration pursuant to Section 2(a) and Section 2(b) hereof. Each Holder
shall pay all underwriting discounts and commissions and transfer taxes, if any,
relating to the sale or disposition of such Holder's Registrable Notes pursuant
to the Shelf Registration Statement.

                                       5
<PAGE>

         (d) An Exchange Offer Registration Statement pursuant to Section 2(a)
hereof or a Shelf Registration Statement pursuant to Section 2(b) hereof will
not be deemed to have become effective unless it has been declared effective by
the SEC; provided that if, after it has been declared effective, the offering of
Registrable Notes pursuant to a Shelf Registration Statement is interfered with
by any stop order, injunction or other order or requirement of the SEC or any
court or other governmental or regulatory agency or body, such Registration
Statement will be deemed not to have become effective during the period of such
interference until the offering of Registrable Notes pursuant to such
Registration Statement may legally resume.

         In the event that either the Exchange Offer is not completed or the
Shelf Registration Statement, if required hereby, is not declared effective on
or prior to November 11, 2002, the interest rate on the Registrable Notes will
be increased by 0.50% per annum until the Exchange Offer is completed or the
Shelf Registration Statement, if required hereby, is declared effective by the
SEC or the Notes become freely tradable under the Securities Act.

         (e) Without limiting the remedies available to the Initial Purchasers
and the Holders, the Company acknowledges that any failure by the Company to
comply with its obligations under Section 2(a) and Section 2(b) hereof may
result in material irreparable injury to the Initial Purchasers or the Holders
for which there is no adequate remedy at law, that it will not be possible to
measure damages for such injuries precisely and that, in the event of any such
failure, the Initial Purchasers or any Holder may obtain such relief as may be
required to specifically enforce the Company's obligations under Section 2(a)
and Section 2(b) hereof.

         3. Registration Procedures. In connection with its obligations pursuant
to Section 2(a) and Section 2(b) hereof, the Company shall as expeditiously as
possible:

         (a) prepare and file with the SEC a Registration Statement on the
appropriate form under the Securities Act, which form (x) shall be selected by
the Company, (y) shall, in the case of a Shelf Registration, be available for
the sale of the Registrable Notes by the selling Holders thereof and (z) shall
comply as to form in all material respects with the requirements of the
applicable form and include all financial statements required by the SEC to be
filed therewith; and use its reasonable best efforts to cause such Registration
Statement to become effective and remain effective for the applicable period in
accordance with Section 2 hereof;

         (b) prepare and file with the SEC such amendments and post-effective
amendments to each Registration Statement as may be necessary to keep such
Registration Statement effective for the applicable period in accordance with
Section 2 hereof and cause each Prospectus to be supplemented by any required
prospectus supplement and, as so supplemented, to be filed pursuant to Rule 424
under the Securities Act; and keep each Prospectus current during the period
described in Section 4(3) of and Rule 174 under the Securities Act that is
applicable to transactions by brokers or dealers with respect to the Registrable
Notes or Exchange Notes;

         (c) in the case of a Shelf Registration, furnish to each Holder of
Registrable Notes, to counsel for the Initial Purchasers, to counsel for such
Holders and to each Underwriter of an Underwritten Offering of Registrable

preliminary Prospectus, and any amendment or supplement thereto, as each such
Holder, counsel or Underwriter may reasonably request, in order to facilitate
the sale or other disposition of the Registrable Notes thereunder; and the
Company consents to the use of such Prospectus and any amendment or supplement
thereto in accordance with

                                       6
<PAGE>

applicable law by each of the selling Holders of Registrable Notes and any such
Underwriters in connection with the offering and sale of the Registrable Notes
covered by and in the manner described in such Prospectus or any amendment or
supplement thereto in accordance with applicable law;

         (d) use its reasonable best efforts to register or qualify the
Registrable Notes under all applicable state securities or blue sky laws of such
jurisdictions as any Holder of Registrable Notes covered by a Registration
Statement shall reasonably request in writing by the time the applicable
Registration Statement is declared effective by the SEC; cooperate with the
Holders in connection with any filings required to be made with the National
Association of Securities Dealers, Inc.; and do any and all other acts and
things that may be reasonably necessary or advisable to enable each Holder to
complete the disposition in each such jurisdiction of the Registrable Notes
owned by such Holder; provided that the Company shall not be required to (i)
qualify as a foreign corporation or other entity or as a dealer in securities in
any such jurisdiction where it would not otherwise be required to so qualify,
(ii) file any general consent to service of process in any such jurisdiction or
(iii) subject itself to taxation in any such jurisdiction in which it is not so
subject;

         (e) in the case of a Shelf Registration, notify each Holder of
Registrable Notes, counsel for such Holders and counsel for the Initial
Purchasers promptly and, if requested by any such Holder or counsel, confirm
such advice in writing (i) when a Registration Statement has become effective
and when any post-effective amendment thereto has been filed and becomes
effective, (ii) of any request by the SEC or any state securities authority for
amendments and supplements to a Registration Statement and Prospectus or for
additional information after the Registration Statement has become effective,
(iii) of the issuance by the SEC or any state securities authority of any stop
order suspending the effectiveness of a Registration Statement or the initiation
of any proceedings for that purpose, (iv) if, between the effective date of a
Registration Statement and the closing of any sale of Registrable Notes covered
thereby, the representations and warranties of the Company contained in any
underwriting agreement, securities sales agreement or other similar agreement,
if any, relating to an offering of such Registrable Notes cease to be true and
correct in all material respects or if the Company receives any notification
with respect to the suspension of the qualification of the Registrable Notes for
sale in any jurisdiction or the initiation of any proceeding for such purpose,
(v) of the happening of any event during the period a Shelf Registration
Statement is effective that makes any statement made in such Registration
Statement or the related Prospectus untrue in any material respect or that
requires the making of any changes in such Registration Statement or Prospectus
in order to make the statements therein not misleading and (vi) of any
determination by the Company that a post-effective amendment to a Registration
Statement would be appropriate;

         (f) use its reasonable best efforts to obtain the withdrawal of any
order suspending the effectiveness of a Registration Statement at the earliest
possible moment and provide immediate notice to each Holder of the withdrawal of
any such order;

         (g) in the case of a Shelf Registration, furnish to each Holder of
Registrable Notes, without charge, at least one conformed copy of each
Registration Statement and any post-effective amendment thereto (without any

<PAGE>

Registrable Notes to be sold and not bearing any restrictive legends and enable

names (consistent with the provisions of the Indenture) as the selling Holders
may reasonably request at least two Business Days prior to the closing of any
sale of Registrable Notes;

         (i) in the case of a Shelf Registration, upon the occurrence of any
event contemplated by Section 3(e)(v) hereof, use its reasonable best efforts to
prepare and file with the SEC a supplement or post-effective amendment to a
Registration Statement or the related Prospectus or any document incorporated
therein by reference or file any other required document so that, as thereafter
delivered to purchasers of the Registrable Notes, such Prospectus will not
contain any untrue statement of a material fact or omit to state a material fact
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading; and the Company shall notify the
Holders of Registrable Notes to suspend use of the Prospectus as promptly as
practicable after the occurrence of such an event, and such Holders hereby agree
to suspend use of the Prospectus until the Company has amended or supplemented
the Prospectus to correct such misstatement or omission;

         (j) a reasonable time prior to the filing of any Registration
Statement, any Prospectus, any amendment to a Registration Statement or
amendment or supplement to a Prospectus or of any document that is to be
incorporated by reference into a Registration Statement or a Prospectus after
initial filing of a Registration Statement, provide copies of such document to
the Initial Purchasers and their counsel (and, in the case of a Shelf
Registration Statement, to the Holders of Registrable Notes and their counsel)
and make such of the representatives of the Company as shall be reasonably
requested by the Initial Purchasers or their counsel (and, in the case of a
Shelf Registration Statement, the Holders of Registrable Notes or their counsel)
available for discussion of such document; and the Company shall not, at any
time after initial filing of a Registration Statement, file any Prospectus, any
amendment of or supplement to a Registration Statement or a Prospectus, or any
document that is to be incorporated by reference into a Registration Statement
or a Prospectus, of which the Initial Purchasers and their counsel (and, in the
case of a Shelf Registration Statement, the Holders of Registrable Notes and
their counsel) shall not have previously been advised and furnished a copy or to
which the Initial Purchasers or their counsel (and, in the case of a Shelf
Registration Statement, the Holders or their counsel) shall reasonably object;

         (k) obtain a CUSIP number for all Exchange Notes or Registrable Notes,
as the case may be, not later than the effective date of a Registration
Statement;

         (l) cause the Indenture to be qualified under the Trust Indenture Act
(if not already so qualified) in connection with the registration of the
Exchange Notes or Registrable Notes, as the case may be; cooperate with the
Trustee and the Holders to effect such changes to the Indenture as may be
required for the Indenture to be so qualified in accordance with the terms of
the Trust Indenture Act; and execute, and use its reasonable best efforts to
cause the Trustee to execute, all documents as may be required to effect such
changes and all other forms and documents required to be filed with the SEC to
enable the Indenture to be so qualified in a timely manner;

         (m) in the case of a Shelf Registration, make available for inspection
by a representative of the Holders of the Registrable Notes, any Underwriter
participating in any disposition pursuant to such Shelf Registration Statement,
and attorneys and accountants designated by the Holders (such representative,
Underwriter, attorneys and accountants referred to herein as "Inspectors"), at
reasonable times and in a reasonable manner, all

                                       8
<PAGE>

pertinent financial and other records, documents and properties of the Company,
and cause the officers, directors and employees of the Company to supply all
information reasonably requested by any such Inspector, Underwriter, attorney or
accountant in connection with a Shelf Registration Statement; provided, however,
that the foregoing inspection and information gathering shall be coordinated on
behalf of the Initial Purchasers, by one counsel designated by the
representative or the Majority Holders. Any such access granted to the
inspectors under this Section 3 shall be subject to the prior receipt by the
Company of written undertakings to preserve the confidentiality of any
information deemed by the Company to be confidential in form and substance
reasonably satisfactory to the Company. Records that the Company determines, in
good faith, to be confidential and any records that it notifies the inspectors
are confidential shall not be disclosed by the inspectors unless (i) the Company
in its sole discretion based on advice of counsel determines 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)
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 such inspector and arising out of, based upon,
relating to or involving this Agreement or any transactions contemplated hereby
or arising hereunder or (iv) the information in such records has been made
generally available to the public. Each Holder will be required to further agree
that it will, upon learning that disclosure of such records is sought in a court
of competent jurisdiction, give notice to the Company and allow the Company to
undertake appropriate action to prevent disclosure of the records deemed
confidential. Each Holder 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
Company unless and until such information is generally available to the public.

         (n) in the case of a Shelf Registration, use its reasonable best
efforts to cause all Registrable Notes to be listed on any securities exchange
or any automated quotation system on which similar securities issued or
guaranteed by the Company are then listed if requested by the Majority Holders,
to the extent such Registrable Notes satisfy applicable listing requirements;

         (o) if reasonably requested by any Holder of Registrable Notes covered
by a Registration Statement, promptly incorporate in a Prospectus supplement or
post-effective amendment such information as required by the applicable rules
and regulations of the SEC and as such Holder specifies should be included
therein relating to the terms of the sale of such Registrable Notes, including
information with respect to the principal amount of Registrable Notes being sold
by such Holder or agent or to any underwriters, the name and description of such
Holder, agent or underwriter, the offering price of such Registrable Note and
any discount, commission or other compensation payable in respect thereof, the
purchase price being paid therefore by such underwriters and with respect to any
other terms of the offering of the Registrable Notes to be sold by such Holder
or agent to such underwriters; and make all required filings of such prospectus
supplement or post-effective amendment promptly after notification of the
matters to be incorporated in such prospectus supplement or post-effective
amendment;

         (p) in the case of a Shelf Registration, enter into such customary
agreements and take all such other actions in connection therewith (including
those requested by the Holders of a majority in principal amount of the
Registrable Notes being sold) in order to expedite or facilitate the disposition
of such Registrable Notes including, but not limited to, an Underwritten
Offering and in such connection, (i) to the extent possible, make such
representations and

                                       9
<PAGE>

warranties to the Holders and any Underwriters of such Registrable Notes with
respect to the business of the Company and its subsidiaries, the Registration
Statement, Prospectus and documents incorporated by reference or deemed
incorporated by reference, if any, in each case, in form, substance and scope as
are customarily made by issuers to underwriters in underwritten offerings and
confirm the same if and when requested, (ii) obtain opinions of counsel to the
Company (which counsel and opinions, in form, scope and substance, shall be
reasonably satisfactory to the Holders and such Underwriters and their
respective counsel) addressed to each selling Holder and Underwriter of
Registrable Notes, covering the matters customarily covered in opinions
requested in underwritten offerings, (iii) obtain "comfort" letters from the
independent certified public accountants of the Company (and, if necessary, any
other certified public accountant of any subsidiary of the Company, or of any
business acquired by the Company for which financial statements and financial
data are or are required to be included in the Registration Statement) addressed
to each selling Holder and Underwriter of Registrable Notes, such letters to be
in customary form and covering matters of the type customarily covered in
"comfort" letters in connection with underwritten offerings and (iv) deliver
such documents and certificates as may be reasonably requested by the Holders of
a majority in principal amount of the Registrable Notes being sold or the
Underwriters, and which are customarily delivered in underwritten offerings, to
evidence the continued validity of the representations and warranties of the
Company made pursuant to clause (i) above and to evidence compliance with any
customary conditions contained in an underwriting agreement.

         In the case of a Shelf Registration Statement, the Company may require
each Holder of Registrable Notes to furnish to the Company such information
regarding such Holder and the proposed disposition by such Holder of such
Registrable Notes as the Company may from time to time reasonably request in
writing.

         In the case of a Shelf Registration Statement, each Holder of
Registrable Notes agrees that, upon receipt of any notice from the Company of
(a) the happening of any event of the kind described in Section 3(e)(iii) or
3(e)(v) hereof, or (b) pending business acquisitions or combinations or other
material transactions, with respect to which the Company has determined that it
is necessary to refrain temporarily from making public offerings of its
securities, such Holder will forthwith discontinue disposition of Registrable
Notes pursuant to such Registration Statement until such Holder's receipt of the
copies of the supplemented or amended Prospectus contemplated by Section 3(i)
hereof and, if so directed by the Company, such Holder will deliver to the
Company all copies in its possession, other than permanent file copies then in
such Holder's possession, of the Prospectus covering such Registrable Notes that
is current at the time of receipt of such notice.

         If the Company shall give any such notice to suspend the disposition of
Registrable Notes pursuant to a Registration Statement, the Company shall extend
the period during which the Registration Statement shall be maintained effective
pursuant to this Agreement by the number of days during the period from and
including the date of the giving of such notice to and including the date when
the Holders shall have received copies of the supplemented or amended Prospectus
necessary to resume such dispositions. The Company may give any such notice only
twice during any 365-day period and any such suspensions shall not exceed 30
days for each suspension and there shall not be more than two suspensions in
effect during any 365-day period.

         The Holders of Registrable Notes covered by a Shelf Registration
Statement who desire to do so may sell such Registrable Notes in an Underwritten
Offering. In any such Underwritten Offering, the investment banker or investment
bankers and manager or managers (the

                                       10
<PAGE>

"Underwriters") that will administer the offering will be selected by the
Majority Holders of the Registrable Notes included in such offering.

         4. Participation of Broker-Dealers in Exchange Offer. (a) The Staff of
the SEC has taken the position that any broker-dealer that receives Exchange
Notes for its own account in the Exchange Offer in exchange for Notes that were
acquired by such broker-dealer as a result of market-making or other trading
activities (a "Participating Broker-Dealer") may be deemed to be an
"underwriter" within the meaning of the Securities Act and must deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such Exchange Notes.

         The Company understands that it is the Staff's position that if the
Prospectus contained in the Exchange Offer Registration Statement includes a
plan of distribution containing a statement to the above effect and the means by
which Participating Broker-Dealers may resell the Exchange Notes, without naming
the Participating Broker-Dealers or specifying the amount of Exchange Notes
owned by them, such Prospectus may be delivered by Participating Broker-Dealers
to satisfy its prospectus delivery obligation under the Securities Act in
connection with resales of Exchange Notes for their own accounts, so long as the
Prospectus otherwise meets the requirements of the Securities Act.

         (b) In light of the above, and notwithstanding the other provisions of
this Agreement, the Company agrees to amend or supplement the Prospectus
contained in the Exchange Offer Registration Statement, as would otherwise be
contemplated by Section 3(i), for a period of up to 180 days after the last
Exchange Date (as such period may be extended pursuant to the penultimate
paragraph of Section 3 of this Agreement), if requested by the Initial
Purchasers or by one or more Participating Broker-Dealers, in order to expedite
or facilitate the disposition of any Exchange Notes by Participating
Broker-Dealers consistent with the positions of the Staff recited in Section
4(a) above. The Company further agrees that Participating Broker-Dealers shall
be authorized to deliver such Prospectus during such period in connection with
the resales contemplated by this Section 4.

         (c) The Initial Purchasers shall have no liability to the Company or
any Holder with respect to any request that they may make pursuant to Section
4(b) above.

         5. Indemnification and Contribution. (a) The Company agrees to
indemnify and hold harmless each Initial Purchaser and each Holder, their
respective affiliates and each Person, if any, who controls any Initial
Purchaser or any Holder within the meaning of Section 15 of the Securities Act
or Section 20 of the Exchange Act, from and against any and all losses, claims,
damages and liabilities (including, without limitation, legal fees and other
expenses incurred in connection with any suit, action or proceeding or any claim
asserted), joint or several, caused by any untrue statement or alleged untrue
statement of a material fact contained in any Registration Statement or any
Prospectus, or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary in order 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 any
information relating to any Initial Purchaser or any Holder furnished to the
Company in writing through J.P. Morgan Securities Inc. or any selling Holder
expressly for use therein. In connection with any Underwritten Offering
permitted by Section 3, the Company will also indemnify the Underwriters, if
any, selling brokers, dealers and similar securities industry professionals
participating in the distribution, their respective affiliates and

                                       11
<PAGE>

each Person who controls such Persons (within the meaning of the Securities Act
and the Exchange Act) to the same extent as provided above with respect to the
indemnification of the Holders, if requested in connection with any Registration
Statement.

         (b) Each Holder agrees, severally and not jointly, to indemnify and
hold harmless the Company, the Initial Purchasers and the other selling Holders,
their respective affiliates, the directors of the Company, each officer of the
Company and each Person, if any, who controls the Company, any Initial Purchaser
and any other selling Holder within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act to the same extent as the indemnity set
forth in paragraph (a) above, but only with respect to any losses, claims,
damages or liabilities caused by any untrue statement or omission or alleged
untrue statement or omission made in reliance upon and in conformity with any
information relating to such Holder furnished to the Company in writing by such
Holder expressly for use in any Registration Statement and any Prospectus.

         (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 indemnification may be sought pursuant to either
paragraph (a) or (b) above, such Person (the "Indemnified Person") shall
promptly notify the Person against whom such indemnification may be sought (the
"Indemnifying Person") in writing; provided that the failure to notify the
Indemnifying Person shall not relieve it from any liability that it may have
under this Section 5 except to the extent that it has been materially prejudiced
(through the forfeiture of substantive rights or defenses) by such failure; and
provided, further, that the failure to notify the Indemnifying Person shall not
relieve it from any liability that it may have to an Indemnified Person
otherwise than under this Section 5. If any such proceeding shall be brought or
asserted against an Indemnified Person and it shall have notified the
Indemnifying Person thereof, the Indemnifying Person shall retain counsel
reasonably satisfactory to the Indemnified Person to represent the Indemnified
Person and any others entitled to indemnification pursuant to this Section 5
that the Indemnifying Person may designate in such proceeding and shall pay the
fees and expenses of such counsel related to such proceeding. 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 to the contrary; (ii) the Indemnifying Person
has failed within a reasonable time to retain counsel reasonably satisfactory to
the Indemnified Person; (iii) the Indemnified Person shall have reasonably
concluded that there may be legal defenses available to it that are different
from or in addition to those available to the Indemnifying Person; or (iv) 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 and agreed that 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 (x) for any Initial Purchaser, its affiliates
and any control Persons of such Initial Purchaser shall be designated in writing
by J.P. Morgan Securities Inc., (y) for any Holder, its affiliates and any
control Persons of such Holder shall be designated in writing by the Majority
Holders and (z) in all other cases shall be designated in writing by the
Company. The Indemnifying Person shall not be liable for any settlement of any
proceeding effected without its written consent, but if settled with such
consent, the Indemnifying Person agrees to indemnify each Indemnified Person
from and against any loss or liability by reason of such settlement. No
Indemnifying Person shall, without

                                       12
<PAGE>

the 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 indemnification 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 or any admission of
fault, culpability or a failure to act by or on behalf of any Indemnified
Person.

         (d) If the indemnification provided for in paragraphs (a) and (b) above
is unavailable to an Indemnified Person or insufficient in respect of any
losses, claims, damages or liabilities referred to therein, then each
Indemnifying Person under such paragraph, in lieu of indemnifying such
Indemnified Person thereunder, shall contribute to the amount paid or payable by
such Indemnified Person as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company from the offering of the Notes and the Exchange
Notes, on the one hand, and by the Holders from receiving Notes or Exchange
Notes registered under the Securities Act, on the other hand, or (ii) if the
allocation provided by clause (i) is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) but also the relative fault of the Company on the one hand and
the Holders on the other in connection with the statements or omissions that
resulted in such losses, claims, damages or liabilities, as well as any other
relevant equitable considerations. The relative fault of the Company on the one
hand and the Holders on the other 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 by the Holders and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

         (e) The Company and the Holders agree that it would not be just and
equitable if contribution pursuant to this Section 5 were determined by pro rata
allocation (even if the Holders 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 paragraph (d) above. The amount paid or payable by
an Indemnified Person as a result of the losses, claims, damages and liabilities
referred to in paragraph (d) above shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses incurred by such
Indemnified Person in connection with any such action or claim. Notwithstanding
the provisions of this Section 5, in no event shall a Holder be required to
contribute any amount in excess of the amount by which the total price at which
the Notes or Exchange Notes sold by such Holder exceeds the amount of any
damages that such Holder 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 remedies provided for in this Section 5 are not exclusive and
shall not limit any rights or remedies that may otherwise be available to any
Indemnified Person at law or in equity.

         (g) The indemnity and contribution provisions contained in this Section
5 shall remain operative and in full force and effect regardless of (i) any
termination of this Agreement, (ii) any investigation made by or on behalf of
the Initial Purchasers or any Holder, their respective affiliates or any Person
controlling any Initial Purchaser or any Holder, or by or on behalf of the
Company, its affiliates or the officers or directors of or any Person
controlling the

                                       13
<PAGE>

Company, (iii) acceptance of any of the Exchange Notes and (iv) any sale of
Registrable Notes pursuant to a Shelf Registration Statement.

         6.       General.

         (a) No Inconsistent Agreements. The Company represents, warrants and
agrees that (i) 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
any other outstanding securities issued or guaranteed by the Company under any
other agreement and (ii) the Company has not entered into, or on or after the
date of this Agreement will enter into, any agreement that is inconsistent with
the rights granted to the Holders of Registrable Notes in this Agreement or
otherwise conflicts with the provisions hereof.

         (b) Amendments and Waivers. The provisions of this Agreement, including
the provisions of this sentence, may not be amended, modified or supplemented,
and waivers or consents to departures from the provisions hereof may not be
given unless the Company has obtained the written consent of Holders of at least
a majority in aggregate principal amount of the outstanding Registrable Notes
affected by such amendment, modification, supplement, waiver or consent;
provided that no amendment, modification, supplement, waiver or consent to any
departure from the provisions of Section 5 hereof shall be effective as against
any Holder of Registrable Notes unless consented to in writing by such Holder.

         (c) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, telex, telecopier, or any courier guaranteeing overnight
delivery (i) if to a Holder, at the most current address given by such Holder to
the Company by means of a notice given in accordance with the provisions of this
Section 6(c), which address initially is, with respect to the Initial
Purchasers, the address set forth in the Purchase Agreement; and (ii) if to the
Company, initially at the Company's address set forth in the Purchase Agreement
and thereafter at such other address, notice of which is given in accordance
with the provisions of this Section 6(c). All such notices and communications
shall be deemed to have been duly given: at the time delivered by hand, if
personally delivered; five Business Days after being deposited in the mail,
postage prepaid, if mailed; when answered back, if telexed; when receipt is
acknowledged, if telecopied; and on the next Business Day if timely delivered to
an air courier guaranteeing overnight delivery. Copies of all such notices,
demands or other communications shall be concurrently delivered by the Person
giving the same to the Trustee, at the address specified in the Indenture.

         (d) Successors and Assigns. This Agreement shall inure to the benefit
of and be binding upon the successors, assigns and transferees of each of the
parties, including, without limitation and without the need for an express
assignment, subsequent Holders; provided that nothing herein shall be deemed to
permit any assignment, transfer or other disposition of Registrable Notes in
violation of the terms of the Purchase Agreement or the Indenture. If any
transferee of any Holder shall acquire Registrable Notes in any manner, whether
by operation of law or otherwise, such Registrable Notes shall be held subject
to all the terms of this Agreement, and by taking and holding such Registrable
Notes such Person shall be conclusively deemed to have agreed to be bound by and
to perform all of the terms and provisions of this Agreement and such Person
shall be entitled to receive the benefits hereof. The Initial Purchasers (in
their capacity as Initial Purchasers) shall have no liability or obligation to
the Company with respect to any failure by a Holder to comply with, or any
breach by any Holder of, any of the obligations of such Holder under this
Agreement.

                                       14
<PAGE>

         (e) Purchases and Sales of Notes. The Company shall not, and shall use
its reasonable best efforts to cause its affiliates (as defined in Rule 405
under the Securities Act) not to, purchase and then resell or otherwise transfer
any Registrable Notes.

         (f) Third Party Beneficiaries. Each Holder shall be a third party
beneficiary to the agreements made hereunder between the Company, on the one
hand, and the Initial Purchasers, on the other hand, and shall have the right to
enforce such agreements directly to the extent it deems such enforcement
necessary or advisable to protect its rights or the rights of other Holders
hereunder.

         (g) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

         (h) Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

         (i) Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York.

         (j) Miscellaneous. This Agreement contains the entire agreement between
the parties relating to the subject matter hereof and supersedes all oral
statements and prior writings with respect thereto. This Agreement may not be
amended or modified except by a writing executed by each of the parties hereto.
Section headings herein are for convenience only and are not a part of this
Agreement. If any term, provision, covenant or restriction contained in this
Agreement is held by a court of competent jurisdiction to be invalid, void or
unenforceable or against public policy, the remainder of the terms, provisions,
covenants and restrictions contained herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated. The Company and
the Initial Purchasers shall endeavor in good faith negotiations to replace the
invalid, void or unenforceable provisions with valid provisions the economic
effect of which comes as close as possible to that of the invalid, void or
unenforceable provisions.

                                       15

         IN WITNESS WHEREOF, the parties have executed this Agreement as of the

                                   ARTICLE IV
                               RETIREMENT BENEFITS

4.1   A Participant's Retirement Benefit under this Plan shall be the excess of

      (i)   the applicable Early, Normal, Late, Deferred Vested or Disability
            Retirement benefit to which the Participant is entitled pursuant to
            the applicable formula set forth in the Hubbell Retirement Plan as
            if the calculation were performed without consideration of the
            Compensation Cap and Defined Benefit Maximum, over

                                       2
<PAGE>
      (ii)  the amount to which the Participant is entitled under the Hubbell
            Retirement Plan.

4.2   Subject to Article X of this Plan, Retirement Benefits available under
      this Plan will be paid in the same form as the Participant has elected for
      payment of the underlying retirement benefits under the Hubbell Retirement
      Plan, and Retirement Benefit payments under this Plan shall be made in the
      same manner as elected by the Participant under the Hubbell Retirement
      Plan; provided, however, that notwithstanding any such election made under
      the Hubbell Retirement Plan, if the Actuarial Equivalent Value (as defined
      in and determined under Section 1.02 of the Hubbell Retirement Plan) of
      the Retirement Benefits payable to the Participant under this Plan is Ten
      Thousand Dollars ($10,000) or less at the time such Retirement Benefits
      are payable under this Plan, such Retirement Benefits shall be payable as
      a lump sum. In addition, Retirement Benefits are payable under the same
      circumstances and with the same restrictions (other than payment limits)
      as benefit payments under the Hubbell Retirement Plan.

                                    ARTICLE V
                         PAYMENT OF RETIREMENT BENEFITS

5.1   All Retirement Benefits hereunder shall be payable in monthly installments
      equal to one-twelfth (1/12th) of the annual amounts determined under this
      Plan; provided, however, that any portion of the Retirement Benefits
      payable under this Plan as a lump sum shall be paid sixty (60) days after
      the date when payments of the same Retirement Benefits under this Plan, if
      payable in the form of an annuity, would otherwise commence, or as soon as
      practicable thereafter, provided the Compensation Committee has approved
      such payment. Any such lump sum distribution of a Participant's or
      Beneficiary's Retirement Benefits under this Plan shall fully satisfy all
      present and future Plan liability with respect to such Participant or
      Beneficiary for such portion or all of such Retirement Benefits so
      distributed.

5.2   If paid in the form of an annuity, a Participant's Retirement Benefit, if
      any, hereunder shall be payable for the life of the Participant,
      commencing on the fifteenth (15th) day of the month commencing after the
      Participant's actual Retirement date under the Hubbell Retirement Plan (or
      any successor defined benefit pension plan). The Participant's last
      payment of Retirement Benefits hereunder shall be made on the fifteenth
      (15th) day of the month in which the Participant dies, unless the
      Participant has designated an eligible Beneficiary at his date of death
      with respect to benefits under the Hubbell Retirement Plan, in which case
      survivor benefit

                                       3
<PAGE>
      payments shall be made to said Beneficiary in accordance with the
      Participant's election regarding payment in such circumstances under the
      Hubbell Retirement Plan; provided, however, that notwithstanding any such
      election made under the Hubbell Retirement Plan, if the Actuarial
      Equivalent Value (as defined in and determined under Section 1.02 of the
      Hubbell Retirement Plan) of the Retirement Benefits payable under this
      Plan to the eligible Beneficiary is Ten Thousand Dollars ($10,000) or less
      at the time such Retirement Benefits are payable under this Plan, such
      Retirement Benefits shall be payable as a lump sum. In the event that the
      Participant has no such eligible Beneficiary at the time of his death, the
      amount, if any, payable under this Plan shall be distributed to the person
      or persons who would otherwise be entitled to receive a distribution of
      the Participant's benefits under the Hubbell Retirement Plan.

                                   ARTICLE VI
                     PRE-RETIREMENT SPOUSE'S EXCESS BENEFIT

6.1   If a married Participant dies prior to his Annuity Starting Date (as
      defined in Section 1.05 of the Hubbell Retirement Plan), leaving a
      surviving Spouse entitled to receive a Pre-Retirement Spouse's Retirement
      Benefit pursuant to Section 4.08 of the Hubbell Retirement Plan, such
      surviving Spouse shall be entitled to receive a Pre-Retirement Spouse's
      Excess Benefit under this Plan equal to the difference between

      (i)   the Pre-Retirement Spouse's Retirement Benefit to which the Spouse
            is entitled under the Hubbell Retirement Plan and

      (ii)  the amount to which the Spouse would be entitled if the calculation
            of the Pre-Retirement Spouse's Retirement Benefit were performed
            without consideration of the Compensation Cap and Defined Benefit
            Maximum.

6.2   Any Pre-Retirement Spouse's Excess Benefit available under this Plan shall
      be payable in the same form and manner as the Pre-Retirement Spouse's
      Retirement Benefit is paid under the Hubbell Retirement Plan, commencing
      on the fifteenth (15th) day of the month in which payment of the
      Pre-Retirement Spouse's Retirement Benefit under the Hubbell Retirement
      Plan commences and terminating on the fifteenth (15th) day of the month in
      which the Spouse's death occurs; provided, however, that any portion of
      the Pre-Retirement Spouse's Excess Benefit payable under this Plan as a
      lump sum shall be paid sixty (60) days after the date when payments of the
      same benefits under this Plan, if payable in the form of an annuity, would
      otherwise commence, or as soon as practicable thereafter, provided the
      Compensation Committee has approved such payment; and provided, further,
      that notwithstanding the above or any election made

                                       4
<PAGE>
      under the Hubbell Retirement Plan, if the Actuarial Equivalent Value
      (as defined in and determined under Section 1.02 of the Hubbell Retirement
      Plan) of the Pre-Retirement Spouse's Excess Benefit payable under this
      Plan to the eligible Spouse is Ten Thousand Dollars ($10,000) or less at
      the time such Pre-Retirement Spouse's Excess Benefit is payable under this
      Plan, such Pre-Retirement Spouse's Excess Benefit shall be payable as a
      lump sum. Any such lump sum distribution of a Pre-Retirement Spouse's
      Excess Benefit under this Plan shall fully satisfy all present and future
      Plan liability with respect to such Spouse for such portion or all of such
      benefits so distributed.

                                   ARTICLE VII
                                     FUNDING

7.1   Benefits under this Plan shall not be prefunded, but shall be paid by the
      Employer as and when they become due as provided herein. No Retirement
      Benefit payable hereunder shall be considered segregated funds and all
      such amounts shall, at all times prior to the payment of the same, be and
      continue to be the property of the Employer, commingled with its other
      assets and available to satisfy the claims of the general creditors of the
      Employer. A Participant's, Beneficiary's and/or Spouse's interests in
      benefits under this Plan shall only be those of unsecured creditors of the
      Employer.

                                  ARTICLE VIII
                               PLAN ADMINISTRATION

8.1   The general administration of this Plan and the responsibility for
      carrying out the provisions hereof shall be vested in the Compensation
      Committee. The Compensation Committee may adopt, subject to the approval
      of the Board of Directors, such rules and regulations as it may deem
      necessary for the proper administration of this Plan, and its decision in
      all matters shall be final, conclusive, and binding.

                                   ARTICLE IX
                            AMENDMENT AND TERMINATION

9.1   The Board of Directors reserves in its sole and exclusive discretion the
      right at any time and from time to time to amend this Plan in any respect
      or terminate this Plan without restriction and without the consent of any
      Participant, Beneficiary or Spouse; provided, however, that no amendment
      or termination of this Plan shall impair the right of any Participant,
      Beneficiary or Spouse to receive benefits earned and accrued hereunder
      prior to such amendment or termination. The Board of Directors shall not

                                       5
<PAGE>
      terminate this Plan solely to accelerate benefits earned and accrued
      hereunder. Any amounts not currently payable to a Participant, Beneficiary
      or Spouse shall revert to the Employer in the event of termination of the
      Plan.

                                    ARTICLE X
                            MISCELLANEOUS PROVISIONS

10.1  No Guarantee of Employment. Nothing contained herein shall be deemed to
      give any individual the right to be retained in the service of the
      Employer or to interfere with the rights of the Employer to discharge any
      individual at any time, with or without cause.

10.2  Non-Alienation of Benefits. No Retirement Benefit payable hereunder may be
      assigned, pledged, mortgaged or hypothecated and, to the extent permitted
      by law, no such Retirement Benefit shall be subject to legal process or
      attachment for the payment of any claims against any person entitled to
      receive the same. Notwithstanding any provision herein to the contrary,
      the Employer may, as the Compensation Committee in its sole and absolute
      discretion shall determine, offset any amount to be paid to a Participant,
      Beneficiary or Spouse hereunder against any amounts which such Participant
      may owe to the Employer or a subsidiary of the Employer.

10.3  Payment to Incompetents. If a Participant, Beneficiary or Spouse entitled
      to receive any benefit hereunder is deemed by the Compensation Committee
      or is adjudged by a court of competent jurisdiction to be legally
      incapable of giving valid receipt and discharge for such benefit, such
      payments shall be paid to such person or persons as the Compensation
      Committee shall designate or to the person's duly appointed guardian. Such
      payments shall, to the extent made, be deemed a complete discharge for
      such payments under this Plan.

10.4  Loss of Benefits. At the sole discretion of the Compensation Committee,
      and after written notice to the Participant, Beneficiary, or Spouse, as
      the case may be, rights to receive any benefit under this Plan may be
      forfeited, suspended, reduced or terminated in cases of gross misconduct
      by the Participant which is reasonably deemed to be prejudicial to the
      interests of the Employer or a subsidiary of the Employer, including but
      not limited to the utilization or disclosure of confidential information
      for gain or otherwise.

10.5  Noncompetition. A Participant shall forfeit for himself and his
      Beneficiary or Spouse any and all benefits pursuant to this Plan if said
      Participant violates the notice provision of this paragraph, or anywhere
      in the United

                                       6

      manages, operates, joins or controls, or participates in the ownership,
      management, operation or control of, or becomes a director or an employee
      of, or a consultant to, any person, firm, or corporation which competes
      with the Employer; provided, however, that the provisions of this Article
      10.5 shall not apply to investments by the Participant in shares of stock
      traded on a national securities exchange or on the national
      over-the-counter market which shall have an aggregate market value, at the
      time of acquisition, of less than two percent (2%) of the outstanding
      shares of such stock. A Participant shall be obligated to give the
      Employer at least sixty (60) days' prior written notice, by registered or
      certified mail, postage prepaid, addressed to the Secretary, Hubbell
      Incorporated, 584 Derby Milford Road, Orange, Connecticut 06477, of his
      intention, directly or indirectly, to own, manage, operate, join or
      control, or participate in the ownership, management, operation or control
      of, or become a director or an employee of, or a consultant to, any
      person, firm, or corporation following which, within a period of sixty
      (60) days from its receipt of such notice, the Employer will mail to the
      Participant by registered or certified mail, postage prepaid, a statement
      of its opinion as to whether said intention of the Participant violates
      this Article 10.5.

10.6  Withholding. Payments made by the Employer under this Plan to any
      Participant, Beneficiary or Spouse shall be subject to such withholding as
      shall, at the time for such payment, be required under any income tax or
      other laws, whether of the United States or any other jurisdiction.

10.7  Expenses. All expenses and costs in connection with the operation of this
      Plan shall be borne by the Employer.

10.8  Governing Law. The provisions of this Plan will be construed according to
      the laws of the State of Connecticut, excluding the provisions of any such
      laws that would require the application of the laws of another

10.9  Gender and Number. The masculine pronoun wherever used herein shall
      include the feminine gender and the feminine the masculine and the
      singular number as used herein shall include the plural and the plural the
      singular unless the context clearly indicates a different meaning.

10.10 Titles and Heading. The titles to articles and headings of sections of
      this Plan are for convenience of reference, and in case of any conflict,
      the text of the Plan, rather than such titles and headings, shall control.

            constitute a Change of Control of the Employer and such action is
            taken.

      (e)   "Continuing Director" shall mean any individual who is a member of

                                prior to the date on which the Participant
