SECTION 2.        HOLDERS

         A Person is deemed to be a holder of Transfer Restricted Securities
(each, a "HOLDER") whenever such Person owns Transfer Restricted Securities.

SECTION 3.        REGISTERED EXCHANGE OFFER

         (a) Unless the Exchange Offer shall not be permitted by applicable
federal law (after the procedures set forth in Section 6(a)(i) below have been
complied with), the Company and the Subsidiary Guarantors shall (i) cause the
Exchange Offer Registration Statement 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 (such 90th day being the "FILING Deadline"), (ii) use its best
efforts to cause such Exchange Offer Registration Statement to become effective
at the earliest possible time, but in no event later than 180 days after the
Closing Date (such 180th day being the "EFFECTIVENESS DEADLINE"), (iii) in
connection with the foregoing, (A) file all pre-effective amendments to such
Exchange Offer Registration Statement as may be necessary in order to cause it
to become effective, (B) file, if applicable, a post-effective amendment to such
Exchange Offer Registration Statement pursuant to Rule 430A under the Act and
(C) cause all necessary filings, if any, in connection with the registration and
qualification of the New Senior Subordinated 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 Exchange Offer
Registration Statement, commence and Consummate the Exchange Offer. The Exchange
Offer shall be on the appropriate form permitting (i) registration of the New
Senior Subordinated Notes to be offered in exchange for the Senior Subordinated
Notes that are Transfer Restricted Securities and (ii) resales of New Senior
Subordinated Notes by Broker-Dealers that tendered into the Exchange Offer
Senior Subordinated

                                       3
   5

Notes that such Broker-Dealer acquired for its own account as a result of market
making activities or other trading activities (other than Senior Subordinated
Notes acquired directly from the Company or any of its Affiliates) as
contemplated by Section 3(c) below.

         (b) The Company and the Subsidiary Guarantors shall use their
respective best efforts to 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 and the
Subsidiary Guarantors shall cause the Exchange Offer to comply with all
applicable federal and state securities laws. No securities other than the New
Senior Subordinated Notes shall be included in the Exchange Offer Registration
Statement. The Company and the Subsidiary Guarantors shall use their respective
best efforts to cause the Exchange Offer to be Consummated on the earliest
practicable date after the Exchange Offer Registration Statement has become
effective, but in no event later than 30 business days thereafter (such 30th day
being the "CONSUMMATION DEADLINE").

         (c) The Company shall include a "Plan of Distribution" section in the
Prospectus contained in the Exchange Offer Registration Statement and indicate
therein that any Broker-Dealer who holds Transfer Restricted Securities that
were acquired for the account of such Broker-Dealer as a result of market-making
activities or other trading activities (other than Senior Subordinated Notes
acquired directly from the Company or any Affiliate of the Company), may
exchange such Transfer Restricted Securities pursuant to the Exchange Offer.
Such "Plan of Distribution" section shall also contain all other information
with respect to such sales by such Broker-Dealers that the Commission may
require in order to permit such sales pursuant thereto, but such "Plan of
Distribution" shall not name any such Broker-Dealer or disclose the amount of
Transfer Restricted Securities held by any such Broker-Dealer, except to the
extent required by the Commission as a result of a change in policy, rules or
regulations after the date of this Agreement.

         Because 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 its initial sale of any New Senior
Subordinated Notes received by such Broker-Dealer in the Exchange Offer, the
Company and the Subsidiary Guarantors shall permit the use of the Prospectus
contained in the Exchange Offer Registration Statement by such Broker-Dealer to
satisfy such prospectus delivery requirement. To the extent necessary to ensure
that the prospectus contained in the Exchange Offer Registration Statement is
available for sales of New Senior Subordinated Notes by Broker-Dealers, the
Company and the Subsidiary Guarantors agree to use their respective reasonable
best efforts to keep the Exchange Offer Registration Statement continuously
effective, supplemented, amended and current as required by and subject to the
provisions of Section 6(a) and (c) hereof and in conformity 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 Consummation Deadline or such shorter period as will terminate when all
Transfer Restricted Securities covered by such Registration Statement have been
sold pursuant thereto. The Company and the Subsidiary Guarantors shall provide
sufficient copies of the latest version of such Prospectus to such
Broker-Dealers, promptly upon request, and in no event later than two business
days after such request, at any time during such period.

                                       4

SECTION 4.        SHELF REGISTRATION

      (a) Shelf Registration. If (i) the Exchange Offer is not permitted by
applicable law (after the Company and the Subsidiary Guarantors have complied
with the procedures set forth in Section 6(a)(i) below) or (ii) if any Holder of
Transfer Restricted Securities shall notify the Company within 20 Business Days
following the Consummation Deadline that (A) such Holder was prohibited by law
or Commission policy from participating in the Exchange Offer or (B) such Holder
may not resell the New Senior Subordinated Notes acquired by it in the Exchange
Offer to the public without delivering a prospectus and the Prospectus contained
in the Exchange Offer Registration Statement is not appropriate or available for
such resales by such Holder or (C) such Holder is a Broker-Dealer and holds
Senior Subordinated Notes acquired directly from the Company or any of its
Affiliates, then the Company and the Subsidiary Guarantors shall:

                  (x) cause to be filed, on or prior to 30 days after the
         earlier of (i) the date on which the Company determines that the
         Exchange Offer Registration Statement cannot be filed as a result of
         clause (a)(i) above and (ii) the date on which the Company receives the
         notice specified in clause (a)(ii) above (such earlier date, the
         "FILING DEADLINE"), a shelf registration statement pursuant to Rule 415
         under the Act (which may be an amendment to the Exchange Offer
         Registration Statement) (in either case, the "SHELF REGISTRATION
         STATEMENT"), relating to all Transfer Restricted Securities, and

                  (y) use their respective best efforts to cause such Shelf
         Registration Statement to become effective on or prior to 90 days after
         the Filing Deadline for the Shelf Registration Statement (such 90th day
         the "EFFECTIVENESS DEADLINE").

      If, after the Company has filed an Exchange Offer Registration Statement
that satisfies the requirements of Section 3(a) above, the Company is required
to file and make effective a Shelf Registration Statement solely because the
Exchange Offer is not permitted under applicable federal law (i.e., clause
(a)(i) above), then the filing of the Exchange Offer Registration Statement
shall be deemed to satisfy the requirements of clause (x) above; provided that,
in such event, the Company shall remain obligated to meet the Effectiveness
Deadline set forth in clause (y).

         To the extent necessary to ensure that the Shelf Registration Statement
is available for sales of Transfer Restricted Securities by the Holders thereof
entitled to the benefit of this Section 4(a) and the other securities required
to be registered therein pursuant to Section 6(b)(ii) hereof, the Company and
the Subsidiary Guarantors shall use their respective best efforts to keep any
Shelf Registration Statement required by this Section 4(a) continuously
effective, supplemented, amended and current as required by and subject to the
provisions of Sections 6(b) and (c) hereof and in conformity 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 (as extended pursuant to Section 6(c)(i)) following the Closing Date, or
such shorter period as will terminate when all Transfer Restricted Securities
covered by such Shelf Registration Statement have been sold pursuant thereto.

         (b) Provision by Holders of Certain Information in Connection with the
Shelf Registration Statement. No Holder of Transfer

                                       5
   7
Restricted Securities may include any of its Transfer Restricted Securities in
any Shelf Registration Statement pursuant to this Agreement unless and until
such Holder furnishes to the Company in writing, within 20 days after receipt of
a request therefor, the information specified in Item 507 or 508 of Regulation
S-K, as applicable, of the Act for use in connection with any Shelf Registration
Statement or Prospectus or preliminary Prospectus included therein. No Holder of
Transfer Restricted Securities shall be entitled to liquidated damages pursuant
to Section 5 hereof unless and until such Holder shall have provided all such
information. Each selling Holder agrees to promptly furnish additional
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 Registration Statement required by this Agreement is not
filed with the Commission on or prior to the applicable Filing Deadline, (ii)
any such Registration Statement has not been declared effective by the
Commission on or prior to the applicable Effectiveness Deadline, (iii) the
Exchange Offer has not been Consummated on or prior to the Consummation Deadline
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 without being succeeded within 5 days by a
post-effective amendment to such Registration Statement that cures such failure
and that is itself declared effective within 5 days of filing such
post-effective amendment to such Registration Statement (each such event
referred to in clauses (i) through (iv), a "REGISTRATION DEFAULT"), then the
Company and the Subsidiary Guarantors hereby jointly and severally agree to pay
to each Holder of Transfer Restricted Securities affected thereby liquidated
damages in an amount equal to $.05 per week per $1,000 in principal amount of
Transfer Restricted Securities held by such Holder for each week or portion
thereof that the Registration Default continues for the first 90-day period
immediately following the occurrence of such Registration Default. The amount of
the liquidated damages shall increase by an additional $.05 per week per $1,000
in principal amount of Transfer Restricted Securities with respect to each
subsequent 90-day period until all Registration Defaults have been cured, up to
a maximum amount of liquidated damages of $.50 per week per $1,000 in principal
amount of Transfer Restricted Securities; provided that the Company and the
Subsidiary Guarantors shall in no event be required to pay liquidated damages
for more than one Registration Default at any given time. Notwithstanding
anything to the contrary set forth herein, (1) upon filing of the Exchange Offer
Registration Statement (and/or, if applicable, the Shelf Registration
Statement), in the case of (i) above, (2) upon the effectiveness of the Exchange
Offer Registration Statement (and/or, if applicable, the Shelf Registration
Statement), in the case of (ii) above, (3) upon Consummation of the Exchange
Offer, in the case of (iii) above, or (4) upon the filing of a post-effective
amendment to the Registration Statement or an additional Registration Statement
that causes the Exchange Offer Registration Statement (and/or, if applicable,
the Shelf Registration Statement) to again be declared effective or made usable
in the case of (iv) above, the liquidated damages payable with respect to the
Transfer Restricted Securities as a result of such clause (i), (ii), (iii) or
(iv), as applicable, shall cease.

         All accrued liquidated damages shall be paid to the Holders entitled
thereto, in the manner provided for the payment of interest in the Indenture, on
each Interest Payment Date, as more fully set forth in the Indenture and the
Notes. Notwithstanding the fact that any securities for which liquidated damages
are due cease to be Transfer Restricted Securities, all obligations of the


                                       6
   8
Company and the Subsidiary Guarantors to pay liquidated damages with respect to
securities shall survive until such time as such obligations with respect to
such securities shall have been satisfied in full.

SECTION 6.        REGISTRATION PROCEDURES

         (a) Exchange Offer Registration Statement. In connection with the
Exchange Offer, the Company and the Subsidiary Guarantors shall (x) comply with
all applicable provisions of Section 6(c) below, (y) use their respective best
efforts to effect such exchange and to permit the resale of New Senior
Subordinated Notes by Broker-Dealers that tendered in the Exchange Offer Senior
Subordinated Notes that such Broker-Dealer acquired for its own account as a
result of its market making activities or other trading activities (other than
Senior Subordinated Notes acquired directly from the Company or any of its
Affiliates) being sold in accordance with the intended method or methods of
distribution thereof, and (z) comply with all of the following provisions:

             (i) If, following the date hereof there has been announced a change
        in Commission policy with respect to exchange offers such as the
        Exchange Offer, that in the reasonable opinion of counsel to the Company
        raises a substantial question as to whether the Exchange Offer is
        permitted by applicable federal law, the Company and the Subsidiary
        Guarantors hereby agree to seek a no-action letter or other favorable
        decision from the Commission allowing the Company and the Subsidiary
        Guarantors to Consummate an Exchange Offer for such Transfer Restricted
        Securities. The Company and the Subsidiary Guarantors hereby agree to
        pursue the issuance of such a decision to the Commission staff level. In
        connection with the foregoing, the Company and the Subsidiary Guarantors
        hereby agree to take all such other reasonable actions as may be
        requested by the Commission or otherwise required in connection with the
        issuance of such decision, including without limitation (A)
        participating in telephonic conferences with the Commission, (B)
        delivering 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 pursuing a resolution (which need not be favorable)
        by the Commission staff.

             (ii) As a condition to its participation in the Exchange Offer,
        each Holder of Transfer Restricted Securities (including, without
        limitation, any Holder who is a Broker Dealer) shall furnish, upon the
        request of the Company, prior to the Consummation of the Exchange Offer,
        a written representation to the Company and the Subsidiary Guarantors
        (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 New Senior Subordinated
        Notes to be issued in the Exchange Offer and (C) it is acquiring the New
        Senior Subordinated Notes in its ordinary course of business. As a
        condition to its participation in the Exchange Offer each Holder using
        the Exchange Offer to participate in a distribution of the New Senior
        Subordinated Notes shall acknowledge and agree that, if the resales are
        of New Senior Subordinated Notes obtained by such Holder in exchange for
        Senior Subordinated Notes acquired directly from the Company or an
        Affiliate thereof, it (1) could not, under

                                       7
   9
        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, if applicable, any no-action letter obtained pursuant to
        clause (i) above), and (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 must 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.

             (iii) Prior to effectiveness of the Exchange Offer Registration
        Statement, the Company and the Subsidiary Guarantors shall provide a
        supplemental letter to the Commission (A) stating that the Company and
        the Subsidiary Guarantors are 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) as interpreted in the Commission's letter to
        Shearman & Sterling dated July 2, 1993, and, if applicable, any
        no-action letter obtained pursuant to clause (i) above, (B) including a
        representation that neither the Company nor any Subsidiary Guarantor has
        entered into any arrangement or understanding with any Person to
        distribute the New Senior Subordinated Notes to be received in the
        Exchange Offer and that, to the best of the Company's and each
        Subsidiary Guarantor's information and belief, each Holder participating
        in the Exchange Offer is acquiring the New Senior Subordinated Notes in
        its ordinary course of business and has no arrangement or understanding
        with any Person to participate in the distribution of the New Senior
        Subordinated Notes received in the Exchange Offer and (C) any other
        undertaking or representation required by the Commission as set forth in
        any no-action letter obtained pursuant to clause (i) above, if
        applicable.

        (b) Shelf Registration Statement. In connection with the Shelf
        Registration Statement, the Company and the Subsidiary Guarantors shall:

            (i) comply with all the provisions of Section 6(c) below and use
        their respective best efforts to effect such registration to permit the
        sale of the Transfer Restricted Securities being sold in accordance with
        the intended method or methods of distribution thereof (as indicated in
        the information furnished to the Company pursuant to Section 4(b)
        hereof), and pursuant thereto the Company and the Subsidiary Guarantors
        will 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
        Securities in accordance with the intended method or methods of
        distribution thereof within the time periods and otherwise in accordance
        with the provisions hereof, and

            (ii) issue, upon the request of any Holder or purchaser of Senior
        Subordinated Notes covered by any Shelf Registration Statement
        contemplated by this Agreement, New Senior Subordinated Notes having an
        aggregate principal amount equal to the aggregate principal amount of
        Senior Subordinated Notes sold pursuant to the Shelf Registration
        Statement and surrendered to the Company for cancellation; the Company
        shall register


                                       8
   10

        New Senior Subordinated Notes on the Shelf Registration Statement for
        this purpose and issue the New Senior Subordinated Notes to the
        purchaser(s) of securities subject to the Shelf Registration Statement
        in the names as such purchaser(s) shall designate.

            (iii) promptly prior to the filing of any document that is to be

        in such document prior to the filing thereof as such selling Holders may
        reasonably request;

            (iv) make available, during reasonable business hours, for

        reasonably necessary to enable them to exercise any applicable due
        diligence responsibilities and cause the Company's and the Subsidiary
        Guarantors' officers, directors and employees to supply all information
        reasonably requested by any such Holder, attorney or accountant in
        connection with such Shelf Registration Statement or any post-effective
        amendment thereto subsequent to the filing thereof and prior to its
        effectiveness. Information that the Company and Subsidiary Guarantors
        determine, in good faith, to be confidential and any information that it
        notifies the Holders is confidential shall not be disclosed by the
        Holders unless (i) the disclosure of such information is necessary to
        avoid or correct a material misstatement or material omission in such
        Registration Statement, (ii) the release of such information is ordered
        pursuant to a subpoena or other order from a court of competent

        unless and until such information is generally available to the public.
        Each selling Holder and its representatives will be required to further
        agree that it will, upon learning that disclosure of such information is
        sought in a court of competent jurisdiction, give notice to the Company
        and the Subsidiary Guarantors and allow the Company and the Subsidiary
        Guarantors to undertake appropriate action to prevent disclosure of the
        information deemed confidential.

            (v) if requested by any Holders in connection with such exchange or
        sale, promptly include in any Shelf Registration Statement or
        Prospectus, pursuant to a supplement or post-effective amendment if
        necessary, such information as such Holders may reasonably request to
        have included therein, including, without limitation, information
        relating to the "Plan of Distribution" of the Transfer Restricted
        Securities; and make all required filings of such Prospectus supplement
        or post-effective amendment as soon as

                                       9
   11

        reasonably practicable after the Company is notified of the matters to
        be included in such Prospectus supplement or post-effective amendment;

            (vi) upon the request of the Holders of at least 50% in aggregate
        principal amount of the then outstanding Transfer Restricted Securities,
        enter into such agreements (including underwriting agreements) and make
        such representations and warranties and take all such other actions in
        connection therewith in order to expedite or facilitate the disposition
        of the Transfer Restricted Securities pursuant to any applicable Shelf
        Registration Statement contemplated by this Agreement as may be

        connection, the Company and the Subsidiary Guarantors shall:

                 Company and each Subsidiary Guarantor by (x) the President or
                 any Vice President and (y) a principal financial or accounting
                 officer of the Company and such Subsidiary Guarantor,
                 confirming, as of the date thereof, the matters set forth in
                 Sections 6(y), 9(a) and 9(b) of the Purchase Agreement and such
                 other similar matters as such Holders may reasonably request;

                 customary form and covering matters of the type customarily
                 covered in comfort letters to underwriters in connection with
                 underwritten offerings, and affirming the matters set forth in
                 the comfort letters delivered pursuant to Section 9(h) of the
                 Purchase Agreement; and

                 (B) deliver such other documents and certificates as may be
         reasonably requested by the selling Holders to evidence compliance with
         the matters covered in clause (A) above and with any customary
         conditions contained in any agreement entered into by the Company and
         the Subsidiary Guarantors pursuant to this clause (vi);

        (c) General Provisions. In connection with any Registration Statement
and any related Prospectus required by this Agreement, the Company and the
Subsidiary Guarantors shall:

                                       10
   12

            (i) use their respective 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 an untrue statement of material fact or omit to
         state any material fact necessary to make the statements therein not
         misleading or (B) not to be effective and usable for resale of Transfer
         Restricted Securities during the period required by this Agreement, the
         Company and the Subsidiary Guarantors shall file promptly an
         appropriate amendment to such Registration Statement curing such
         defect, and, if Commission review is required, use their respective
         best efforts to cause such amendment to be declared effective as soon
         as practicable.

            (ii) prepare and file with the Commission such amendments and
         post-effective amendments to the applicable Registration Statement as
         may be necessary to keep such Registration Statement effective for the
         applicable period set forth in Section 3 or 4 hereof, as the case may
         be; cause the Prospectus to be supplemented by any required Prospectus
         supplement, and as so supplemented to be filed pursuant to Rule 424
         under the Act, and to comply fully with Rules 424, 430A and 462, as
         applicable, under the Act in a timely manner; and comply with the
         provisions of the Act with respect to the disposition of all securities
         covered by such Registration Statement during the applicable period in
         accordance with the intended method or methods of distribution by the
         sellers thereof set forth in such Registration Statement or supplement
         to the Prospectus;

            (iii) advise each Holder promptly and, if requested by such Holder,
         confirm such advice in writing, (A) when the Prospectus or any
         Prospectus supplement or post-effective amendment has been filed, and,
         with respect to any applicable Registration Statement or any
         post-effective amendment thereto, when the same has become effective,
         (B) of any request by the Commission for amendments to the Registration
         Statement or amendments or supplements to the Prospectus or for
         additional information relating thereto, (C) of the issuance by the
         Commission of any stop order suspending the effectiveness of the
         Registration Statement under the Act or of the suspension by any state
         securities commission of the qualification of the Transfer Restricted
         Securities for offering or sale in any jurisdiction, or the initiation
         of any proceeding for any of the preceding purposes, (D) of the
         existence of any fact or the happening of any event that makes any
         statement of a material fact made in the Registration Statement, the
         Prospectus, any amendment or supplement thereto or any document
         incorporated by reference therein untrue, or that requires the making
         of any additions to or changes in the Registration Statement in order
         to make the statements therein not misleading, or that requires the
         making of any additions to or changes in the Prospectus in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading. If at any time the Commission
         shall issue any stop order suspending the effectiveness of the
         Registration Statement, or any state securities commission or other
         regulatory authority shall issue an order suspending the qualification
         or exemption from qualification of the Transfer Restricted Securities
         under state securities or Blue Sky laws, the Company and the Subsidiary
         Guarantors shall use their respective best efforts to obtain the
         withdrawal or lifting of such order at the earliest possible time;

                                       11
   13
                (iv) subject to Section 6(c)(i), if any fact or event
        contemplated by Section 6(c)(iii)(D) above shall exist or have occurred,
        prepare a supplement or post-effective amendment to the Registration
        Statement or related Prospectus or any document incorporated therein by
        reference or file any other required document so that, as thereafter
        delivered to the purchasers of Transfer Restricted Securities, the
        Prospectus will not contain an untrue statement of a material fact or
        omit to state any material fact necessary to make the statements
        therein, in the light of the circumstances under which they were made,
        not misleading;

                (v) furnish to each selling Holder in connection with such sale,
        if any, before filing with the Commission, copies of any Registration
        Statement or any related Prospectus included therein or any amendments
        or supplements to any such Registration Statement or Prospectus
        (including all documents incorporated by reference after the initial
        filing of such Registration Statement), which documents will be subject
        to the review and comment of such Holders in connection with such sale,
        if any, for a period of at least five business days, and the Company
        will not file any such Registration Statement or related Prospectus or
        any amendment or supplement to any such Registration Statement or
        Prospectus (including all such documents incorporated by reference) to
        which such selling Holders shall reasonably object within five business
        days after the receipt thereof. A selling Holder shall be deemed to have
        reasonably objected to such filing if such Registration Statement,
        amendment, related Prospectus or supplement, as applicable, as proposed
        to be filed, contains an untrue statement of a material fact or omit to
        state any material fact necessary to make the statements therein not
        misleading or fails to comply with the applicable requirements of the
        Act;

                (vi) furnish to each Holder who requests in connection with such
        exchange or sale, without charge, at least one copy of the Registration
        Statement, as first filed with the Commission, and of each amendment
        thereto, including all documents incorporated by reference therein and
        all exhibits (including exhibits incorporated therein by reference);

                (vii) deliver to each Holder without charge, as many copies of
        the Prospectus (including each preliminary prospectus) and any amendment
        or supplement thereto as such Persons reasonably may request; the
        Company and the Subsidiary Guarantors hereby consent to the use (in
        accordance with law) of the Prospectus and any amendment or supplement
        thereto by each selling Holder in connection with the offering and the
        sale of the Transfer Restricted Securities covered by the Prospectus or
        any amendment or supplement thereto;

                (viii) prior to any public offering of Transfer Restricted
        Securities, cooperate with the selling Holders and their counsel in
        connection with the registration and qualification of the Transfer
        Restricted Securities under the securities or Blue Sky laws of such
        jurisdictions as the selling Holders may request and do any and all
        other acts or things reasonably necessary or advisable to enable the
        disposition in such jurisdictions of the Transfer Restricted Securities
        covered by the applicable Registration Statement; provided, however,
        that neither the Company nor any Subsidiary Guarantor shall be required
        to register or qualify as a foreign corporation where it is not now so
        qualified or to take any action that

                                       12
   14
        would subject it to the service of process in suits or to taxation,
        other than as to matters and transactions relating to the Registration
        Statement, in any jurisdiction where it is not now so subject;

                (ix) in connection with any sale of Transfer Restricted
        Securities that will result in such securities no longer being Transfer
        Restricted Securities, cooperate with the selling Holders to facilitate
        the timely preparation and delivery of certificates representing
        Transfer Restricted Securities to be sold and not bearing any
        restrictive legends; and to register such Transfer Restricted Securities
        in such denominations and such names as the selling Holders may request
        at least two business days prior to such sale of Transfer Restricted
        Securities;

                (x) use their respective best efforts to cause the disposition
        of the Transfer Restricted Securities covered by the Registration
        Statement to be registered with or approved by such other governmental
        agencies or authorities as may be necessary to enable the seller or
        sellers thereof to consummate the disposition of such Transfer
        Restricted Securities, subject to the proviso contained in clause (viii)
        above;

                (xi) provide a CUSIP number for all Transfer Restricted
        Securities not later than the effective date of a Registration Statement
        covering such Transfer Restricted Securities and provide the Trustee
        under the Indenture with printed certificates for the Transfer
        Restricted Securities which are in a form eligible for deposit with the
        Depository Trust Company;

                (xii) otherwise use their respective best efforts to comply with
        all applicable rules and regulations of the Commission, and make
        generally available to its security holders with regard to any
        applicable Registration Statement, as soon as practicable, a
        consolidated earnings statement meeting the requirements of Rule 158
        (which need not be audited) covering a twelve-month period beginning
        after the effective date of the Registration Statement (as such term is
        defined in paragraph (c) of Rule 158 under the Act);

                (xiii) cause the Indenture to be qualified under the TIA not
        later than the effective date of the first Registration Statement
        required by this Agreement and, in connection therewith, cooperate with
        the Trustee and the Holders 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; and

                (xiv) provide promptly to each Holder, upon request, each
        document filed with the Commission pursuant to the requirements of
        Section 13 or Section 15(d) of the Exchange Act.

        (d) Restrictions on Holders. Each Holder agrees by acquisition of a
Transfer Restricted Security that, upon receipt of the notice referred to in
Section 6(c)(iii)(C) or any notice from the Company of the existence of any fact
of the kind described in Section 6(c)(iii)(D) hereof (in each


                                       13
   15
case, a "SUSPENSION NOTICE"), such Holder will forthwith discontinue disposition
of Transfer Restricted Securities pursuant to the applicable Registration
Statement until (i) such Holder has received copies of the supplemented or
amended Prospectus contemplated by Section 6(c)(iv) hereof, or (ii) such Holder
is advised in writing by the Company that the use of the Prospectus may be
resumed, and has received copies of any additional or supplemental filings that
are incorporated by reference in the Prospectus (in each case, the
"RECOMMENCEMENT DATE"). Each Holder receiving a Suspension Notice hereby agrees
that it will either (i) destroy any Prospectuses, other than permanent file
copies, then in such Holder's possession which have been replaced by the Company
with more recently dated Prospectuses or (ii) deliver to the Company (at the
Company's expense) all copies, other than permanent file copies, then in such
Holder's possession of the Prospectus covering such Transfer Restricted
Securities that was current at the time of receipt of the Suspension 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 a number of days
equal to the number of days in the period from and including the date of
delivery of the Suspension Notice to the date of delivery of the Recommencement
Date.

SECTION 7.        REGISTRATION EXPENSES

      (a) All expenses incident to the Company's and the Subsidiary Guarantors'

of any annual audit and the fees and expenses of any Person, including special

      (b) In connection with any Registration Statement required by this
Agreement (including, without limitation, the Exchange Offer Registration

   16
firm shall be chosen by the Holders of a majority in principal amount of the

SECTION 8.        INDEMNIFICATION

      (a) The Company and the Subsidiary Guarantors agree, jointly and
severally, to indemnify and hold harmless each Holder, its directors, officers
and each Person, if any, who controls such Holder (within the meaning of Section
15 of the Act or Section 20 of the Exchange Act), from and against any and all
losses, claims, damages, liabilities, judgments, (including without limitation,
any reasonable legal or other reasonable expenses incurred in connection with
investigating or defending any matter, including any action that could give rise
to any such losses, claims, damages, liabilities or judgments) caused by any
untrue statement or alleged untrue statement of a material fact contained in any
Registration Statement, preliminary prospectus or Prospectus (or any amendment
or supplement thereto) provided by the Company to any Holder or any prospective
purchaser of New Senior Subordinated Notes or registered Senior Subordinated
Notes, or caused by any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, except insofar as such losses, claims, damages, liabilities or
judgments are caused by an untrue statement or omission or alleged untrue
statement or omission that is based upon information relating to any of the
Holders furnished in writing to the Company by any of the Holders.

      (b) Each Holder of Transfer Restricted agrees, severally and not jointly,
to indemnify and hold harmless the Company and the Subsidiary Guarantors, and
their respective directors and officers, and each person, if any, who controls
(within the meaning of Section 15 of the Act or Section 20 of the Exchange Act)
the Company, or the Subsidiary Guarantors to the same extent as the foregoing
indemnity from the Company and the Subsidiary Guarantors set forth in section
(a) above, but only with reference to information relating to such Holder
furnished in writing to the Company by such Holder expressly for use in any
Registration Statement. In no event shall any Holder, its directors, officers or
any Person who controls such Holder be liable or responsible for any amount in
excess of the amount by which the total amount received by such Holder with
respect to its sale of Transfer Restricted Securities pursuant to a Registration
Statement exceeds (i) the amount paid by such Holder for such Transfer
Restricted Securities and (ii) the amount of any damages that such Holder, its
directors, officers or any Person who controls such Holder has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission.

      (c) In case any action shall be commenced involving any person in respect
of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the
"INDEMNIFIED PARTY"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "INDEMNIFYING PERSON") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 8(a) and 8(b), a Holder shall not be required to assume the
defense of such action pursuant to this Section 8(c), but may employ separate
counsel and participate in the defense thereof, but the fees and expenses of
such counsel, except as provided below, shall be at the expense of the Holder).
Any indemnified




                                       15
   17
party shall have the right to employ separate counsel in any such action and
participate in the defense thereof, but the fees and expenses of such counsel
shall be at the expense of the indemnified party unless (i) the employment of
such counsel shall have been specifically authorized in writing by the
indemnifying party, (ii) the indemnifying party shall have failed to assume the
defense of such action or employ counsel reasonably satisfactory to the
indemnified party, (iii) the named parties to any such action (including any
impleaded parties) include both the indemnified party and the indemnifying
party, and the indemnified party shall have been advised by such counsel that
there may be one or more legal defenses available to it which are different from
or additional to those available to the indemnifying party (in which case the
indemnifying party shall not have the right to assume the defense of such action
on behalf of the indemnified party) or (iv) there exists an actual Conflict of
interest between original counsel and such indemnified party. In any such case,
the indemnifying party shall not, in connection with any one action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances, be liable for the fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) for all indemnified parties and all such fees and expenses shall be
reimbursed as they are incurred. Such firm shall be designated in writing by a
majority of the Holders, in the case of the parties indemnified pursuant to
Section 8(a), and by the Company and Subsidiary Guarantors, in the case of
parties indemnified pursuant to Section 8(b). The indemnifying party shall
indemnify and hold harmless the indemnified party from and against any and all
losses, claims, damages, liabilities and judgments by reason of any settlement
of any action (i) effected with its prior written consent or (ii) effected
without its prior written consent if the settlement is entered into more than
twenty business days after the indemnifying party shall have received a request
from the indemnified party for reimbursement for the fees and expenses of
counsel (in any case where such fees and expenses are at the expense of the
indemnifying party) and, prior to the date of such settlement, the indemnifying
party shall have failed to comply with such reimbursement request. No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement or compromise of, or consent to the entry of
judgment with respect to, any pending or threatened action in respect of which
the indemnified party is or could have been a party and indemnity or
contribution may be or could have been sought hereunder by the indemnified
party, unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability on claims that
are or could have been the subject matter of such action and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act, by or on behalf of the indemnified party.

      (d) To the extent that the indemnification provided for in this Section 8
is unavailable to an indemnified party in respect of any losses, claims,
damages, liabilities or judgments referred to therein, then each indemnifying
party, in lieu of indemnifying such indemnified party, shall contribute to the
amount paid or payable by such indemnified party as a result of such losses,
claims, damages, liabilities or judgments (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company and the
Subsidiary Guarantors, on the one hand, and the Holders, on the other hand, from
their sale of Transfer Restricted Securities or (ii) if the allocation provided
by clause 8(d)(i) is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause
8(d)(i) above but also the relative fault of the Company and the Subsidiary
Guarantors, on the one hand, and of the Holder, on the other hand, in connection
with the statements or omissions which resulted in such losses, claims, damages,



                                       16
   18
liabilities or judgments, as well as any other relevant equitable
considerations. The relative fault of the Company and the Subsidiary Guarantors,
on the one hand, and of the 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 Subsidiary Guarantor, on
the one hand, or by the Holder, on the other hand, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The amount paid or payable by a party as a result of
the losses, claims, damages, liabilities and judgments referred to above shall
be deemed to include, subject to the limitations set forth in the second
paragraph of Section 8(a), any legal or other fees or expenses reasonably
incurred by such party in connection with investigating or defending any action
or claim.

         The Company, the Subsidiary Guarantors and each Holder agree that it
would not be just and equitable if contribution pursuant to this Section 8(d)
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 which does not
take account of the equitable considerations referred to in the immediately
preceding paragraph. The amount paid or payable by an indemnified party as a
result of the losses, claims, damages, liabilities or judgments referred to in
the immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any matter,
including any action that could have given rise to such losses, claims, damages,
liabilities or judgments. Notwithstanding the provisions of this Section 8, no
Holder, its directors, its officers or any Person, if any, who controls such
Holder shall be required to contribute, in the aggregate, any amount in excess
of the amount by which the total received by such Holder with respect to the
sale of Transfer Restricted Securities pursuant to a Registration Statement
exceeds (i) the amount paid by such Holder for such Transfer Restricted
Securities and (ii) the amount of any damages which 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 Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The Holders' obligations to contribute pursuant to this
Section 8(c) are several in proportion to the respective principal amount of
Transfer Restricted Securities held by each Holder hereunder and not joint.

SECTION 9.        RULE 144A AND RULE 144

         The Company and each Subsidiary Guarantor agrees with each Holder, for
so long as any Transfer Restricted Securities remain outstanding and during any
period in which the Company or such Subsidiary Guarantor (i) is not subject to
Section 13 or 15(d) of the Exchange Act, to make available, upon request of any
Holder, to such Holder or beneficial owner of Transfer Restricted Securities in
connection with any sale thereof and any prospective purchaser of such Transfer
Restricted Securities designated by such Holder or beneficial owner, the
information required by Rule 144A(d)(4) under the Act in order to permit resales
of such Transfer Restricted Securities pursuant to Rule 144A, and (ii) is
subject to Section 13 or 15 (d) of the Exchange Act, to make all filings
required thereby in a timely manner in order to permit resales of such Transfer
Restricted Securities pursuant to Rule 144.

SECTION 10.       MISCELLANEOUS

      (a) Remedies. The Company and the Subsidiary Guarantors acknowledge and
agree that any failure by the Company and/or the Subsidiary Guarantors to comply
with their respective obligations under Sections 3 and 4 hereof may result in
material irreparable injury to the Initial Purchaser or the Holders for which
there is no adequate remedy at law, that it will not be possible to measure
damages for such injuries precisely and that, in the event of any such failure,
the Initial Purchaser or any Holder may obtain such relief as may be required to
specifically enforce the Company's and the Subsidiary Guarantors' obligations
under Sections 3 and 4 hereof. The Company and the Subsidiary Guarantors further
agree to waive the defense in any action for specific performance that a remedy
at law would be adequate.

      (b) No Inconsistent Agreements. Neither the Company nor any Subsidiary
Guarantor will, 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.
Neither the Company nor any Subsidiary Guarantor has previously entered into any
agreement granting any registration rights with respect to its securities to any
Person. 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 and the Subsidiary Guarantors' securities under any agreement in
effect on the date hereof.

      (c) 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 hereof may not be given unless (i) in the case of Section 5
hereof and this Section 10(c)(i), the Company has obtained the written consent
of Holders of all outstanding Transfer Restricted Securities and (ii) in the
case of all other provisions hereof, the Company has obtained the written
consent of Holders of a majority of the outstanding principal amount of Transfer
Restricted Securities (excluding Transfer Restricted Securities held by the
Company or its Affiliates). Notwithstanding the foregoing, a waiver or consent
to departure from the provisions hereof that relates exclusively to the rights
of Holders whose Transfer Restricted Securities are being tendered pursuant to
the Exchange Offer, and that does not affect directly or indirectly the rights
of other Holders whose Transfer Restricted 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 Securities subject to
such Exchange Offer.

      (d) Third Party Beneficiary. The Holders shall be third party
beneficiaries to the agreements made hereunder between the Company and the
Subsidiary Guarantors, 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
they may deem such enforcement necessary or advisable to protect its rights or
the rights of Holders hereunder.

      (e) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail
(registered or certified, return receipt requested), telecopier, or air courier

transfer or other disposition of Transfer Restricted Securities in violation of
the terms hereof or of the Purchase Agreement or the Indenture. If any
transferee of any Holder shall acquire Transfer Restricted Securities in any
manner, whether by operation of law or otherwise, such Transfer Restricted
Securities shall be held subject to all of the terms of this Agreement, and by
taking and holding such Transfer Restricted Securities such Person shall be
conclusively deemed to have agreed to be bound by and to perform all of the
terms and provisions of this Agreement, including the restrictions on resale set
forth in this Agreement and, if applicable, the Purchase Agreement, and such
Person shall be entitled to receive the benefits hereof.

      (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.

CONFLICT OF LAW RULES THEREOF.

      (j) Severability. In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby.

      (k) Entire Agreement. This Agreement is intended by the parties as a final
expression of their agreement and intended to be a complete and exclusive
statement of the agreement and understanding of the parties hereto in respect of
the subject matter contained herein. There are no restrictions, promises,
warranties or undertakings, other than those set forth or referred to herein
with respect to the registration rights granted with respect to the Transfer
Restricted Securities. This Agreement supersedes all prior agreements and
understandings between the parties with respect to such subject matter.

      (l) Limitation of Liability. Each of Instron Realty Trust ("Trust") and
IRT-II ("Trust II")is a voluntary association with transferable shares organized
under the laws of the Commonwealth of Massachusetts (more commonly known as a
"Massachusetts Business Trust") and all persons dealing with each of Trust and
Trust II must look solely to the property of each of Trust and Trust II for the
enforcement of any claims against each of Trust and Trust II. Neither the
trustees, officers, agents nor shareholders of either Trust or Trust II assume
any liability for obligations entered into on its behalf. In no event shall the
Initial Purchaser seek or attempt to obtain any recovery or judgment against any
trustee, officer, director, employee or shareholder of either Trust or Trust II.
The Declaration of Trust, dated as of April 23, 1957, of Trust and the
Declaration of Trust, dated October 19, 1998, of Trust II are on file with the
