            This Registration Rights Agreement (this "AGREEMENT") is dated as of
June 16, 2000, among DAYTON SUPERIOR CORPORATION, an Ohio corporation (the

Guarantees are collectively referred to herein as the "SECURITIES". In order to
induce the Initial Purchasers to enter into the Purchase Agreement, the Issuers
have agreed to provide the registration rights set forth in this Agreement for

2.    EXCHANGE OFFER

            (a) To the extent not prohibited by any applicable law or applicable
interpretation of the staff of the SEC, the Issuers shall use all commercially
reasonable efforts to file with the SEC, no later than the Filing Date, a
Registration Statement (the "EXCHANGE OFFER REGISTRATION STATEMENT") on an
appropriate registration form with respect to a registered offer (the "EXCHANGE
OFFER") to exchange any and all of the Registrable Notes for a like aggregate
principal amount of notes of the Company, guaranteed by the Guarantors, that are
identical in all material respects to the Securities (the "EXCHANGE NOTES"),
except that (i) the Exchange Notes shall contain no restrictive legend thereon
and (ii) interest on each Exchange Note shall accrue (A) from the later of (i)
the last interest payment date on which interest was paid on the Note
surrendered in exchange therefor, or (ii) if the Note is surrendered for
exchange on a date which is subsequent to the record date for an interest
payment date to occur on or after the date of such exchange and as to which
interest will be paid, the date of such interest payment date or (B) if no
interest has been paid on such Note, from the Issue Date, and which are entitled
to the benefits of the Indenture or a trust indenture which is identical in all
material respects to the Indenture (other than such changes to the Indenture or
any such identical trust indenture as are necessary to comply with the TIA) and
which, in either case, has been qualified under the TIA. The Exchange Offer
shall comply with all applicable tender offer rules and regulations under the
Exchange Act and other applicable law. The Issuers shall use all commercially
reasonable efforts to (x) cause the Exchange Offer Registration Statement to be
declared effective under the Securities Act on or before the Effectiveness Date;
(y) keep the Exchange Offer open for not less than 30 days (or longer if
required by applicable law) after the date that notice of the Exchange Offer is
mailed to Holders; and (z) consummate the Exchange Offer on or prior to the
185th day after the Issue Date. If, after the Exchange Offer Registration
Statement is initially declared effective by the SEC, the Exchange Offer or the
issuance of the Exchange Notes thereunder is interfered with by any stop order,
injunction or other order or requirement of the SEC or any other governmental
agency or court, the Exchange Offer Registration Statement shall be deemed not
to have become effective for purposes of this Agreement during the period of
such interference, until the Exchange Offer may legally resume.

            Each Holder that participates in the Exchange Offer will be
required, as a condition to its participation in the Exchange Offer, to
represent to the Issuers in writing (which may be contained in the applicable
letter of transmittal) 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 such Holder will have no arrangement or
understanding with any Person to participate in the distribution of the Exchange
Notes in violation of the

<PAGE>
                                      -6-

provisions of the Securities Act, (iii) such Holder is not an "affiliate" (as
defined in Rule 405 promulgated under the Securities Act) of the Company, (iv)
if such Holder is not a broker-dealer, such Holder is not engaged in, and does
not intend to engage in, the distribution of Exchange Notes, (v) if such Holder
is a broker-dealer that will receive Exchange Notes for its own account in
exchange for Notes that were acquired as a result of market-making or other
trading activities, such Holder will deliver a prospectus in connection with any
resale of such Exchange Notes and (vi) the Holder is not acting on behalf of any
persons or entities who could not truthfully make the foregoing representations.
Such Holder will also be required to make such other representations as may be
necessary under applicable SEC rules, regulations or interpretations to render
available the use of Form S-4 or any other appropriate form under the Securities
Act.

            Upon consummation of the Exchange Offer in accordance with this
Section 2, the provisions of this Agreement shall continue to apply solely with
respect to Registrable Notes that are Private Exchange Notes, Exchange Notes as
to which Section 2(c)(iv) is applicable and Exchange Notes held by Participating
Broker-Dealers (as defined), and the Issuers shall have no further obligation to
register Registrable Notes (other than Private Exchange Notes and other than in
respect of any Exchange Notes as to which clause 2(c)(iv) hereof applies)
pursuant to Section 3 hereof.

            No securities other than the Exchange Notes shall be included in the
Exchange Offer Registration Statement.

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

            The Issuers shall use all commercially reasonable efforts to keep
the Exchange Offer Registration Statement effective and to amend and supplement
the Prospectus contained therein in order to permit such Prospectus to be
lawfully delivered by all Persons subject to the prospectus delivery
requirements of the Securities Act for such period of time as is neces-

<PAGE>
                                      -7-

sary to comply with applicable law in connection with any resale of the Exchange
Notes covered thereby, PROVIDED, HOWEVER, that such period shall not be required
to exceed 180 days, or such longer period if extended pursuant to the last
sentence of Section 5 (the "APPLICABLE Period").

            If, prior to consummation of the Exchange Offer, the Initial
Purchasers hold any Notes acquired by them that have the status of an unsold
allotment in the initial distribution, the Issuers upon the request of the
Initial Purchasers shall simultaneously with the delivery of the Exchange Notes
in the Exchange Offer, issue and deliver to the Initial Purchasers, in exchange
(the "PRIVATE EXCHANGE") for such Notes held by the Initial Purchasers, a like
principal amount of notes (the "PRIVATE EXCHANGE NOTES") of the Issuers,
guaranteed by the Guarantors, that are identical in all material respects to the
Exchange Notes except for the placement of a restrictive legend on such Private
Exchange Notes. The Private Exchange Notes shall be issued pursuant to the same
indenture as the Exchange Notes and bear the same CUSIP number as the Exchange
Notes.

            In connection with the Exchange Offer, the Issuers shall:

                        (1) mail, or cause to be mailed, to each Holder of
            record entitled to participate in the Exchange Offer a copy of the
            Prospectus forming part of the Exchange Offer Registration
            Statement, together with an appropriate letter of transmittal and
            related documents;

                        (2) use their best efforts to keep the Exchange Offer
            open for not less than 30 days after the date that notice of the
            Exchange Offer is mailed to Holders (or longer if required by
            applicable law);

                        (3) utilize the services of a depositary for the
            Exchange Offer with an address in the Borough of Manhattan, The City
            of New York;

                        (4) permit Holders to withdraw tendered Securities at
            any time prior to the close of business, New York time, on the last
            business day on which the Exchange Offer shall remain open; and

                        (5) otherwise comply in all material respects with all
            applicable laws, rules and regulations.

            As soon as practicable after the close of the Exchange Offer and the
Private Exchange, if any, the Issuers shall:

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

<PAGE>
                                      -8-

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

                        (3) cause the Trustee to authenticate and deliver
            promptly to each Holder of Securities, Exchange Notes or Private
            Exchange Notes, as the case may be, equal in principal amount to the
            Securities of such Holder so accepted for exchange.

            The Exchange Offer and the Private Exchange shall not be subject to
any conditions, other than that (i) the Exchange Offer or the Private Exchange,
as the case may be, does not violate applicable law or any applicable
interpretation of the staff of the SEC, (ii) no action or proceeding shall have
been instituted or threatened in any court or by any governmental agency which
might materially impair the ability of the Issuers to proceed with the Exchange
Offer or the Private Exchange, (iii) all governmental approvals shall have been
obtained, which approvals the Issuers deem necessary for the consummation of the
Exchange Offer or the Private Exchange, (iv) there has not been any material
change, or development involving a prospective material change, in the business
or financial affairs of the Issuers which, in the reasonable judgment of the
Issuers, would materially impair the Issuers' ability to consummate the Exchange
Offer or the Private Exchange, and (v) there has not been proposed, adopted or
enacted any law, statute, rule or regulation which, in the reasonable judgment
of the Issuers, would materially impair the Issuers' ability to consummate the
Exchange Offer or the Private Exchange or have a material adverse effect on the
Issuers if the Exchange Offer or the Private Exchange was consummated. In the
event that the Issuers are unable to consummate the Exchange Offer or the
Private Exchange due to any event listed in clauses (i) through (v) above, the
Issuers shall not be deemed to have breached any covenant under this Section 2.

            The Exchange Notes and the Private Exchange Notes shall be issued
under (i) the Indenture or (ii) an indenture identical in all material respects
to the Indenture and which, in either case, has been qualified under the TIA or
is exempt from such qualification and shall provide that the Exchange Notes
shall not be subject to the transfer restrictions set forth in the Indenture.
The Indenture or such indenture shall provide that the Exchange Notes, the
Private Exchange Notes and the Securities shall vote and consent together on all
matters as one class and that none of the Exchange Notes, the Private Exchange
Notes or the Securities will have the right to vote or consent as a separate
class on any matter.

            (c) If (i) because of any change in law or in currently prevailing
interpretations of the staff of the SEC, the Issuers are not permitted to effect
the Exchange Offer, (ii) the Exchange Offer is not consummated within 185 days
of the Issue Date, (iii) the holder of Private Exchange Notes so requests in
writing to the Issuers within 60 days after the consummation of the Exchange
Offer, or (iv) in the case of any Holder that participates in the Exchange
Offer, such Holder does not receive Exchange Notes on the date of the exchange
that may be sold without restriction under state and federal securities laws
(other than due solely to the

<PAGE>
                                      -9-

status of such Holder as an affiliate of one of the Issuers within the meaning
of the Securities Act), then in the case of each of clauses (i) to and including
(iv) of this sentence, the Issuers shall promptly deliver to the Holders and the
Trustee written notice thereof (the "SHELF NOTICE") and shall file a Shelf
Registration pursuant to Section 3 hereof.

3.    SHELF REGISTRATION

            If at any time a Shelf Notice is delivered as contemplated by
Section 2(c) hereof, then:

            (a) SHELF REGISTRATION. The Issuers shall file with the SEC a
Registration Statement for an offering to be made on a continuous basis pursuant
to Rule 415 covering all of the Registrable Notes not exchanged in the Exchange
Offer, Private Exchange Notes and Exchange Notes as to which Section 2(c)(iv) is
applicable (the "INITIAL SHELF REGISTRATION"). The Issuers shall use all
commercially reasonable efforts to file with the SEC the Initial Shelf
Registration on or before the applicable Filing Date. The Initial Shelf
Registration shall be on Form S-3 or another appropriate form permitting
registration of such Registrable Notes for resale by Holders in the manner or
manners designated by them (including, without limitation, one or more
underwritten offerings). The Issuers shall not permit any securities other than
the Registrable Notes to be included in the Initial Shelf Registration or any
Subsequent Shelf Registration (as defined below).

            The Issuers shall, subject to applicable law or applicable
interpretation of the staff of the SEC, use all commercially reasonable efforts
to cause the Initial Shelf Registration to be declared effective under the
Securities Act on or prior to the Effectiveness Date and to keep the Initial
Shelf Registration continuously effective under the Securities Act until the
date which is two years from the Issue Date or such shorter period ending when
(i) all Registrable Notes covered by the Initial Shelf Registration have been
sold in the manner set forth and as contemplated in the Initial Shelf
Registration or cease to be outstanding or (ii) a Subsequent Shelf Registration
covering all of the Registrable Notes covered by and not sold under the Initial
Shelf Registration or an earlier Subsequent Shelf Registration has been declared
effective under the Securities Act (the "EFFECTIVENESS PERIOD"), PROVIDED,
HOWEVER, that the Effectiveness Period in respect of the Initial Shelf
Registration shall be extended to the extent required to permit dealers to
comply with the applicable prospectus delivery requirements of Rule 174 under
the Securities Act and as otherwise provided herein.

            No holder of Registrable Notes may include any of its Registrable
Notes in any Shelf Registration Statement pursuant to this Agreement unless and
until such holder furnishes to the Company in writing, within 15 business days
after receipt of a request therefor, such information concerning such Holder
required to be included in any Shelf Registration Statement or Prospectus or
preliminary prospectus included therein. No holder of Registrable Notes shall be
entitled to Additional Interest pursuant to Section 4 hereof unless and until

<PAGE>
                                      -10-

such holder shall have provided all such information. Each holder of Registrable
Notes as to which any Shelf Registration Statement is being effected agrees to
furnish promptly to the Company all information required to be disclosed in
order to make information previously furnished to the Company by such Holder not
materially misleading.

            (b) SUBSEQUENT SHELF REGISTRATIONS. If the Initial Shelf
Registration or any Subsequent Shelf Registration ceases to be effective for any
reason at any time during the Effectiveness Period (other than because of the
sale of all of the securities registered thereunder), the Issuers shall use all
commercially reasonable efforts to obtain the prompt withdrawal of any order
suspending the effectiveness thereof, and in any event shall within 30 days of
such cessation of effectiveness amend the Initial Shelf Registration in a manner
to obtain the withdrawal of the order suspending the effectiveness thereof, or
file an additional "shelf" Registration Statement pursuant to Rule 415 covering
all of the Registrable Notes covered by and not sold under the Initial Shelf
Registration or an earlier Subsequent Shelf Registration (each, a "SUBSEQUENT
SHELF REGISTRATION"). If a Subsequent Shelf Registration is filed, the Issuers
shall use their best efforts to cause the Subsequent Shelf Registration to be
declared effective under the Securities Act as soon as practicable after such
filing and to keep such subsequent Shelf Registration continuously effective for
a period equal to the number of days in the Effectiveness Period less the
aggregate number of days during which the Initial Shelf Registration or any
Subsequent Shelf Registration was previously continuously effective. As used
herein the term "SHELF REGISTRATION" means the Initial Shelf Registration and
any Subsequent Shelf Registration.

            (c) SUPPLEMENTS AND AMENDMENTS. The Issuers shall promptly
supplement and amend any Shelf Registration if required by the rules,
regulations or instructions applicable to the registration form used for such
Shelf Registration, if required by the Securities Act, or if reasonably
requested by the Holders of a majority in aggregate principal amount of the
Registrable Notes covered by such Registration Statement or by any underwriter
of such Registrable Notes.

4.    ADDITIONAL INTEREST

            (a) The Issuers and the Initial Purchasers agree that the Holders
will suffer damages if the Issuers fail to fulfill their obligations under
Section 2 or Section 3 hereof and that it would not be feasible to ascertain the
extent of such damages with precision. Accordingly, the Issuers agree to pay, as
liquidated damages, additional interest on the Notes ("ADDITIONAL INTEREST")
under the circumstances and to the extent set forth below (each of which shall
be given independent effect):

                        (i) if (A) neither the Exchange Offer Registration
            Statement nor the Initial Shelf Registration has been filed on or
            prior to the applicable Filing Date or (B) notwithstanding that the
            Issuers have consummated or will consummate the Ex

            change Offer, the Issuers are required to file a Shelf Registration
            and such Shelf Registration is not filed on or prior to the Filing
            Date applicable thereto, then, commencing on the day after any such
            Filing Date, Additional Interest shall accrue on the principal
            amount of the Securities at a rate of 0.50% per annum for the first
            90 days immediately following each such Filing Date, and such
            Additional Interest rate shall increase by an additional 0.50% per
            annum at the beginning of each subsequent 90-day period; or

                        (ii) if (A) neither the Exchange Offer Registration
            Statement nor the Initial Shelf Registration is declared effective
            by the SEC on or prior to the relevant Effectiveness Date or (B)
            notwithstanding that the Issuers have consummated or will consummate
            the Exchange Offer, the Issuers are required to file a Shelf
            Registration and such Shelf Registration is not declared effective
            by the SEC on or prior to the Effectiveness Date in respect of such
            Shelf Registration, then, commencing on the day after such
            Effectiveness Date, Additional Interest shall accrue on the
            principal amount of the Securities at a rate of 0.50% per annum for
            the first 90 days immediately following the day after such
            Effectiveness Date, and such Additional Interest rate shall increase
            by an additional 0.50% per annum at the beginning of each subsequent
            90-day period; or

                        (iii) if (A) the Issuers have not exchanged Exchange
            Notes for all Securities validly tendered in accordance with the
            terms of the Exchange Offer on or prior to the 185th day after the
            Issue Date or (B) if applicable, a Shelf Registration has been
            declared effective and such Shelf Registration ceases to be
            effective at any time during the Effectiveness Period, then
            Additional Interest shall accrue on the principal amount of the
            Securities at a rate of 0.50% per annum for the first 90 days
            commencing on the (x) 185th day after the Issue Date in the case of
            (A) above, or (y) the day such Shelf Registration ceases to be
            effective in the case of (B) above, and such Additional Interest
            rate shall increase by an additional 0.50% per annum at the
            beginning of each such subsequent 90-day period;

PROVIDED, HOWEVER, that the Additional Interest rate on the Notes may not accrue
under more than one of the foregoing clauses (i)-(iii) at any one time and at no
time shall the aggregate amount of Additional Interest exceed 1.00% per annum;
PROVIDED, FURTHER, HOWEVER, that (1) upon the filing of the applicable Exchange
Offer Registration Statement or the applicable Shelf Registration Statement as
required hereunder (in the case of clause (i) above of this Section 4), (2) upon
the effectiveness of the Exchange Offer Registration Statement or the applicable
Shelf Registration Statement as required hereunder (in the case of clause (ii)
of this Section 4), or (3) upon the exchange of the applicable Exchange Notes
for all Securities tendered (in the case of clause (iii)(A) of this Section 4),
or upon the effectiveness of the applicable Shelf Registration Statement which
had ceased to remain effective (in the case of (iii)(B)

<PAGE>
                                      -12-

of this Section 4), Additional Interest on the Notes in respect of which such
events relate as a result of such clause (or the relevant subclause thereof), as
the case may be, shall cease to accrue.

            (b) The Issuers shall notify the Trustee within three business days
after each and every date on which an event occurs in respect of which
Additional Interest is required to be paid (an "EVENT DATE"). Any amounts of
Additional Interest due pursuant to (a)(i), (a)(ii) or (a)(iii) of this Section
4 will be payable in cash semiannually on each June 15 and December 15, (to the
holders of record on the June 1 and December 1 immediately preceding such
dates), commencing with the first such date occurring after any such Additional
Interest commences to accrue. The amount of Additional Interest will be
determined by multiplying the applicable Additional Interest rate by the
principal amount of the Registrable Notes, multiplied by a fraction, the
numerator of which is the number of days such Additional Interest rate was
applicable during such period (determined on the basis of a 360-day year
comprised of twelve 30-day months and, in the case of a partial month, the
actual number of days elapsed), and the denominator of which is 360.

5.    REGISTRATION PROCEDURES

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

            (a) Prepare and file with the SEC prior to the applicable Filing
Date, a Registration Statement or Registration Statements as prescribed by
Sections 2 or 3 hereof, and use their reasonable best efforts to cause each such
Registration Statement to become effective and remain effective as provided
herein; PROVIDED, HOWEVER, that, if (1) such filing is pursuant to Section 3
hereof, or (2) a Prospectus contained in the Exchange Offer Registration
Statement filed pursuant to Section 2 hereof is required to be delivered under
the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period relating thereto, before filing any
Registration Statement or Prospectus or any amendments or supplements thereto,
the Issuers shall furnish to and afford the Holders of the Registrable Notes
included in such Registration Statement or each such Participating
Broker-Dealer, as the case may be, their counsel and the managing underwriters,
if any, a reasonable opportunity to review copies of all such documents
(including copies of any documents to be incorporated by reference therein and
all exhibits thereto) proposed to be filed (in each case at least five days
prior to such filing, or such later date as is reasonable under the
circumstances). The Issuers shall not file any Registration Statement or
Prospectus or any amendments or supplements thereto if the Holders of a majority
in aggregate principal amount of the Registrable Notes included in such
Registration Statement, or any such Participating Broker-Dealer, as the

<PAGE>
                                      -13-

case may be, their counsel, or the managing underwriters, if any, shall
reasonably object on a timely basis.

            (b) Prepare and file with the SEC such amendments and post-effective
amendments to each Shelf Registration Statement or Exchange Offer Registration
Statement, as the case may be, as may be necessary to keep such Registration
Statement continuously effective for the Effectiveness Period or the Applicable
Period, as the case may be; cause the related Prospectus to be supplemented by
any Prospectus supplement required by applicable law, and as so supplemented to
be filed pursuant to Rule 424 (or any similar provisions then in force)
promulgated under the Securities Act; and comply with the provisions of the
Securities Act and the Exchange Act applicable to each of them with respect to
the disposition of all securities covered by such Registration Statement as so
amended or in such Prospectus as so supplemented and with respect to the
subsequent resale of any securities being sold by a Participating Broker-Dealer
covered by any such Prospectus. The Issuers shall be deemed not to have used all
commercially reasonable efforts to keep a Registration Statement effective
during the Effectiveness Period or the Applicable Period, as the case may be,
relating thereto if any Issuer voluntarily takes any action that would result in
selling Holders of the Registrable Notes covered thereby or Participating
Broker-Dealers seeking to sell Exchange Notes not being able to sell such
Registrable Notes or such Exchange Notes during that period unless such action
is required by applicable law or permitted by this Agreement.

            (c) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in the Exchange Offer Registration
Statement filed pursuant to Section 2 hereof is required to be delivered under
the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period relating thereto from whom the Issuers have
received written notice that it will be a Participating Broker-Dealer in the
Exchange Offer, notify the selling Holders of Registrable Notes, or each such
Participating Broker-Dealer, as the case may be, their counsel and the managing
underwriters, if any, promptly (but in any event within two business days), and
confirm such notice in writing, (i) when a 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, when the same
has become effective under the Securities Act (including in such notice a
written statement that any Holder may, upon request in writing, obtain, at the
sole expense of the Issuers, one conformed copy of such Registration Statement
or post-effective amendment including financial statements and schedules,
documents incorporated or deemed to be incorporated by reference and exhibits),
(ii) of the issuance by the SEC of any stop order suspending the effectiveness
of a Registration Statement or of any order preventing or suspending the use of
any preliminary prospectus or the initiation of any proceedings for that
purpose, (iii) if at any time when a prospectus is required by the Securities
Act to be delivered in connection with sales of the Registrable Notes or resales
of Exchange Notes by Participating Broker-Dealers the representations and
warranties of the Issuers contained in any agreement (includ-

<PAGE>
                                      -14-

ing any underwriting agreement) contemplated by Section 5(l) hereof cease to be
true and correct in all material respects, (iv) of the receipt by any Issuer of
any notification with respect to the suspension of the qualification or
exemption from qualification of a Registration Statement or any of the
Registrable Notes or the Exchange Notes to be sold by any Participating
Broker-Dealer for offer or sale in any jurisdiction, or the initiation or
threatening of any proceeding for such purpose, (v) of the happening of any
event, the existence of any condition or any information becoming known that
makes any statement made in such Registration Statement or related Prospectus or
any document incorporated or deemed to be incorporated therein by reference
untrue in any material respect or that requires the making of any changes in or
amendments or supplements to such Registration Statement, Prospectus or
documents so that, in the case of the Registration Statement, it will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein
not misleading, and that in the case of the Prospectus, it will not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading, and (vi) of the
Issuers' determination that a post-effective amendment to a Registration
Statement would be appropriate.

            (d) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in the Exchange Offer Registration
Statement filed pursuant to Section 2 hereof is required to be delivered under
the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period, use its reasonable best efforts to prevent
the issuance of any order suspending the effectiveness of a Registration
Statement or of any order preventing or suspending the use of a Prospectus or
suspending the qualification (or exemption from qualification) of any of the
Registrable Notes or the Exchange Notes to be sold by any Participating
Broker-Dealer, for sale in any jurisdiction, and, if any such order is issued,
to use its reasonable best efforts to obtain the withdrawal of any such order at
the earliest possible moment.

            (e) If a Shelf Registration is filed pursuant to Section 3 and if
requested by the managing underwriter or underwriters (if any), the Holders of a
majority in aggregate principal amount of the Registrable Notes being sold in
connection with an underwritten offering or any Participating Broker-Dealer, (i)
as promptly as practicable incorporate in a prospectus supplement or
post-effective amendment such information as the managing underwriter or
underwriters (if any), such Holders, any Participating Broker-Dealer or counsel
for any of them reasonably request to be included therein, (ii) make all
required filings of such prospectus supplement or such post-effective amendment
as soon as practicable after an Issuer has received notification of the matters
to be incorporated in such prospectus supplement or post-effective amendment,
and (iii) supplement or make amendments to such Registration Statement.

<PAGE>
                                      -15-

            (f) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in the Exchange Offer Registration
Statement filed pursuant to Section 2 hereof is required to be delivered under
the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period, furnish to each selling Holder of
Registrable Notes and to each such Participating Broker-Dealer who so requests
and to their respective counsel and each managing underwriter, if any, at the
sole expense of the Issuers, one conformed copy of the Registration Statement or
Registration Statements and each post-effective amendment thereto, including
financial statements and schedules, and, if requested in writing, all documents
incorporated or deemed to be incorporated therein by reference and all exhibits.

            (g) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in the Exchange Offer Registration
Statement filed pursuant to Section 2 hereof is required to be delivered under
the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period, deliver to each selling Holder of
Registrable Notes, or each such Participating Broker-Dealer, as the case may be,
their respective counsel, and the underwriters, if any, at the sole expense of
the Issuers, as many copies of the Prospectus or Prospectuses (including each
form of preliminary prospectus) and each amendment or supplement thereto and if
requested in writing, any documents incorporated by reference therein as such
Persons may reasonably request; and, subject to the last paragraph of this
Section 5, the Issuers hereby consent to the use of such Prospectus and each
amendment or supplement thereto (provided the manner of such use complies with
any limitations resulting from any applicable state securities "Blue Sky" laws
as provided in writing to such Holders by the Company and subject to the
provisions of this Agreement) each of the selling Holders of Registrable Notes
or each such Participating Broker-Dealer, as the case may be, and the
underwriters or agents, if any, and dealers (if any), in connection with the
offering and sale of the Registrable Notes covered by, or the sale by
Participating Broker-Dealers of the Exchange Notes pursuant to, such Prospectus
and any amendment or supplement thereto.

            (h) Prior to any public offering of Registrable Notes or any
delivery of a Prospectus contained in the Exchange Offer Registration Statement
by any Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period, use its best efforts to register or qualify, and to cooperate
with the selling Holders of Registrable Notes or each such Participating
Broker-Dealer, as the case may be, the managing underwriter or underwriters, if
any, and their respective counsel in connection with the registration or
qualification (or exemption from such registration or qualification) of such
Registrable Notes for offer and sale under the securities or Blue Sky laws of
such jurisdictions within the United States as any selling Holder, Participating
Broker-Dealer, or the managing underwriter or underwriters reasonably request in
writing; PROVIDED, HOWEVER, that where Exchange Notes held by Participating
Broker-Dealers or Registrable Notes are offered other than through an
underwritten offering, the Issuers agree to cause their counsel to perform Blue
Sky investigations and file

<PAGE>
                                      -16-

registrations and qualifications required to be filed pursuant to this Section
5(h), keep each such registration or qualification (or exemption therefrom)
effective during the period such Registration Statement is required to be kept
effective and do any and all other acts or things reasonably necessary or
advisable to enable the disposition in such jurisdictions of the Exchange Notes
held by Participating Broker-Dealers or the Registrable Notes covered by the
applicable Registration Statement; PROVIDED, HOWEVER, that no Issuer shall be
required to (A) qualify generally to do business in any jurisdiction where it is
not then so qualified, (B) take any action that would subject it to general
service of process in any such jurisdiction where it is not then so subject or
(C) subject itself to taxation in excess of a nominal dollar amount in any such
jurisdiction where it is not then so subject.

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

            (j) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in the Exchange Offer Registration
Statement filed pursuant to Section 2 hereof is required to be delivered under
the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange

prepare and (subject to Section 5(a) hereof) file with the SEC, at the sole
expense of the Issuers, a supplement or post-effective amendment to the
Registration Statement or a supplement to the related Prospectus or any document
incorporated or deemed to be incorporated therein by reference, or file any
other required document so that, as thereafter delivered to the purchasers of
the Registrable Notes being sold thereunder or to the purchasers of the Exchange
Notes to whom such Prospectus will be delivered by a Participating
Broker-Dealer, any such Prospectus will not contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading. Notwithstanding the foregoing, the Issuers
shall not be required to amend or supplement a Registration Statement, any
related Prospectus or any document incorporated therein by reference, in the
event that, and for a period not to exceed an aggregate of 60 days in any
calendar year if, (i) an event occurs and is continuing as a result of which the
Shelf Registration would, in the Issuers' good faith judgment, contain an untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements therein, in the light of the circumstances under which
they were made, not misleading, and (ii) (a) the Issuers determine in their good
faith judgment that the disclosure of such event at such time would have a
material adverse effect on the business, opera-

<PAGE>
                                      -17-

tions or prospects of the Issuers or (b) the disclosure otherwise relates to a
pending material business transaction that has not yet been publicly disclosed.

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

            (l) In connection with any underwritten offering of Registrable
Notes pursuant to a Shelf Registration, enter into an underwriting agreement as
is customary in underwritten offerings of debt securities similar to the
Securities in form and substance reasonably satisfactory to the Issuers and take
all such other actions as are reasonably requested by the managing underwriter
or underwriters in order to expedite or facilitate the registration or the
disposition of such Registrable Notes and, in such connection, (i) make such
representations and warranties to, and covenants with, the underwriters with
respect to the business of the Issuers and the subsidiaries of the Issuers
(including any acquired business, properties or entity, if applicable) and the
Registration Statement, Prospectus and documents, if any, incorporated or deemed
to be incorporated by reference therein, in each case, as are customarily made
by issuers to underwriters in underwritten offerings of debt securities similar
to the Securities, and confirm the same in writing if and when requested in form
and substance reasonably satisfactory to the Issuers; (ii) upon the request of
Holders of 10% of the Registrable Notes, obtain the written opinions of counsel
to the Issuers and written updates thereof in form, scope and substance
reasonably satisfactory to the managing underwriter or underwriters, addressed
to the underwriters covering the matters customarily covered in opinions
reasonably requested in underwritten offerings and such other matters as may be
reasonably requested by the managing underwriter or underwriters; (iii) upon the
request of Holders of 10% of the Registrable Notes, use its reasonable best
efforts to obtain "cold comfort" letters and updates thereof in form, scope and
substance reasonably satisfactory to the managing underwriter or underwriters
from the independent public accountants of the Issuers (and, if necessary, any
other independent public accountants of the Issuers, any subsidiary of the
Issuers or of any business acquired by the Issuers for which financial
statements and financial data are, or are required to be, included or
incorporated by reference in the Registration Statement), addressed to each of
the underwriters, such letters to be in customary form and covering matters of
the type customarily covered in "cold comfort" letters in connection with
underwritten offerings of debt securities similar to the Securities and such
other matters as reasonably requested by the managing underwriter or
underwriters as permitted by the Statement on Auditing Standards No. 72; and
(iv) if an underwriting agreement is entered into, cause the same to contain
indemnification provisions and procedures no less favorable to the sellers and
underwriters, if any, than those set forth in Section 7 hereof (or such other
provisions and procedures acceptable to Holders of a majority in aggregate
principal amount of Registrable Notes covered by such Registration Statement and
the managing underwriter or underwriters or agents, if any).

<PAGE>
                                      -18-

The above shall be done at each closing under such underwriting agreement, or as
and to the extent required thereunder.

            (m) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in the Exchange Offer Registration
Statement filed pursuant to Section 2 hereof is required to be delivered under
the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period, make available for inspection by any selling
Holder of such Registrable Notes being sold, or each such Participating
Broker-Dealer, as the case may be, any underwriter participating in any such
disposition of Registrable Notes, if any, and any attorney, accountant or other
agent retained by any such selling Holder or each such Participating
Broker-Dealer, as the case may be, or underwriter (collectively, the
"INSPECTORS"), at the offices where normally kept, during reasonable business
hours, all financial and other records, pertinent corporate documents and
instruments of the Issuers and subsidiaries of the Issuers (collectively, the
"RECORDS") as shall be reasonably necessary to enable them to exercise any
applicable due diligence responsibilities, and cause the officers, directors and
employees of the Issuers and any of their subsidiaries to supply all information
reasonably requested by any such Inspector in connection with such Registration
Statement and Prospectus. The foregoing inspection and information gathering
shall be coordinated on behalf of the other parties by one counsel designated by
such parties as described in Section 6(b) hereof. Each Inspector shall agree in
writing that it will keep the Records confidential and that it will not disclose
any of the Records that the Issuers determine, in good faith, to be confidential
(i) the release of such Records is ordered pursuant to a subpoena or other order
from a court of competent jurisdiction, or (ii) the information in such Records
has been made generally available to the public; PROVIDED, HOWEVER, that prior
notice shall be provided as soon as practicable to the Issuers of the potential
disclosure of any information by such Inspector pursuant to clause (i) of this
sentence to permit the Issuers to obtain a protective order or take other
appropriate action to prevent the disclosure of such information at the
Company's sole expense (or waive the provisions of this paragraph (m)) and that
such Inspector shall take such actions as are reasonably necessary to protect
the confidentiality of such information (if practicable) to the extent such
action is otherwise not inconsistent with, an impairment of or in derogation of
the rights and interests of the Holder or any Inspector.

            (n) Provide an indenture trustee for the Registrable Notes or the
Exchange Notes, as the case may be, and cause the Indenture or the trust
indenture provided for in Section 2(a) hereof, as the case may be, to be
qualified under the TIA not later than the effective date of the first
Registration Statement relating to the Registrable Notes; and in connection
therewith, cooperate with the trustee under any such indenture and the Holders
of the Registrable Notes to effect such changes to such indenture as may be
required for such indenture to be so qualified in accordance with the terms of
the TIA; and execute, and use its best efforts to cause such trustee to execute,
all documents as may be required to effect such changes, and all

<PAGE>
                                      -19-

other forms and documents required to be filed with the SEC to enable such
indenture to be so qualified in a timely manner.

            (o) Comply with all applicable rules and regulations of the SEC and
make generally available to its securityholders with regard to any applicable
Registration Statement, a consolidated earnings statement satisfying the
provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or
any similar rule promulgated under the Securities Act) no later than 60 days
after the end of any fiscal quarter (or 120 days after the end of any 12-month
period if such period is a fiscal year) (i) commencing at the end of any fiscal
quarter in which Registrable Notes are sold to underwriters in a firm commitment
or best efforts underwritten offering and (ii) if not sold to underwriters in
such an offering, commencing on the first day of the first fiscal quarter of the
Issuers after the effective date of a Registration Statement, which statements
shall cover said 12-month periods.

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

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

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

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

            The Issuers may require each seller of Registrable Notes as to which
any registration is being effected to furnish to the Issuers such information
regarding such seller and the distribution of such Registrable Notes as the
Issuers may, from time to time, reasonably re-

<PAGE>
                                      -20-

quest. The Issuers may exclude from such registration the Registrable Notes of
any seller so long as such seller fails to furnish such information within a
reasonable time after receiving such request. Each seller as to which any Shelf
Registration is being effected agrees to furnish promptly to the Issuers all
information required to be disclosed in order to make the information previously
furnished to the Issuers by such seller not materially misleading.

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

6.    REGISTRATION EXPENSES

            (a) All fees and expenses incident to the performance of or

Notes being registered in a Shelf Registration or the reasonable fees and
disbursements of not more than one counsel (in addition to appropriate local
counsel) chosen by the Holders of a majority in aggregate principal amount of
the Registrable Notes to be included in such Registration Statement and (ii)
reimburse reasonable out-of-pocket expenses (other than legal expenses and other
sale commissions or similar costs) of Holders of Registrable Notes incurred in
connection with the registration and sale of Registrable Notes pursuant to a
Shelf Registration or in connection with exchange of the Registrable Notes in
connection with the Exchange Offer. In addition, the Issuers shall reimburse the
Initial Purchasers for the reasonable fees and expenses of one counsel in
connection with the Exchange Offer, which shall be Cahill Gordon & Reindel, and
shall not be required to pay any other legal expenses in connection therewith.

7.    INDEMNIFICATION

            (a) Each of the Issuers, jointly and severally, agrees to indemnify
and hold harmless each Holder of Registrable Notes and each Participating
Broker-Dealer selling Exchange Notes during the Applicable Period, the
affiliates, officers, directors, representatives, employees and agents of each
such Person, and each Person, if any, who controls any such Person within the
meaning of either Section 15 of the Securities Act or Section 20 of the Exchange
Act (each, a "PARTICIPANT"), from and against any and all losses, claims,
damages, judgments, liabilities and expenses (including, without limitation, the
reasonable legal fees and other expenses actually incurred in connection with
any suit, action or proceeding or any claim asserted) caused by, arising out of
or based upon any untrue statement or alleged untrue statement of a material
fact contained in any Registration Statement (or any amendment thereto) or
Prospectus (as amended or supplemented if the Issuers shall have furnished any
amendments or supplements thereto) or any preliminary prospectus, or caused by,
arising out

<PAGE>
                                      -22-

of or based upon any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein,
in the case of the Prospectus in light of the circumstances under which they
were made, not misleading, EXCEPT insofar as such losses, claims, damages or
liabilities are caused by any untrue statement or omission or alleged untrue
statement or omission made in reliance upon and in conformity with information
relating to any Participant furnished to the Issuers in writing by such
Participant expressly for use therein and with respect to any preliminary
Prospectus, to the extent that any such loss, claim, damage or liability arises
solely from the fact that any Participant sold Notes to a person to whom there
was not sent or given a copy of the Prospectus (as amended or supplemented) at
or prior to the written confirmation of such sale if the Issuers shall have
previously furnished copies thereof to the Participant in accordance herewith
and the Prospectus (as amended or supplemented) would have corrected any such
untrue statement or omission.

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

            (c) If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any Person in respect of which indemnity may be sought pursuant to either of the
two preceding paragraphs, such Person (the "INDEMNIFIED PERSON") shall promptly
notify the Persons against whom such indemnity may be sought (the "INDEMNIFYING
PERSONS") in writing, and the Indemnifying Persons, upon request of the
Indemnified Person, shall retain counsel reasonably satisfactory to the
Indemnified Person to represent the Indemnified Person and any others the
Indemnifying Person may reasonably designate in such proceeding and shall pay
the reasonable fees and expenses actually incurred by such counsel related to
such proceeding; PROVIDED, HOWEVER, that the failure to so notify the
Indemnifying Persons will not relieve it from any liability under paragraph (a)
or (b) above unless and to the extent such failure results in the forfeiture by
the Indemnifying Person of substantial rights and defenses and the Indemnifying
Person was not otherwise aware of such action or claim. 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 Persons and the Indemnified Person shall have
mutually agreed to the contrary, (ii) the Indemnifying Persons shall have failed
within a reasonable period of time to retain counsel reasonably satisfactory to

<PAGE>
                                      -23-

the Indemnified Person or (iii) the named parties in any such proceeding
(including any impleaded parties) include both any Indemnifying Person and the
Indemnified Person and representation of both parties by the same counsel would
be inappropriate due to actual or potential differing interests between them. It
is understood that the Indemnifying Persons shall not, in connection with such
proceeding or separate but substantially similar related proceeding in the same
jurisdiction arising out of the same general allegations, 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 promptly as they are incurred. Any such separate firm for the
Participants and such control Persons of Participants shall be designated in
writing by Participants who sold a majority in interest of Registrable Notes and
Exchange Notes sold by all such Participants and shall be reasonably acceptable
to the Issuers, and any such separate firm for the Issuers, their affiliates,
officers, directors, representatives, employees and agents and such control
Persons of such Issuer shall be designated in writing by such Issuer and shall
be reasonably acceptable to the Holders.

            The Indemnifying Person shall not be liable for any settlement of
any proceeding effected without its prior written consent (which consent shall
not be unreasonably withheld or delayed), but if settled with such consent or if
there be a final non-appealable judgment for the plaintiff for which the
Indemnified Person is entitled to indemnification pursuant to this Agreement,
each Indemnifying Person agrees to indemnify and hold harmless each Indemnified
Person from and against any loss or liability by reason of such settlement or
judgment. No Indemnifying Person shall, without the prior written consent of the
Indemnified Person (which consent shall not be unreasonably withheld or
delayed), effect any settlement or compromise of any pending or threatened
proceeding in respect of which any Indemnified Person is or could have been a
party, or indemnity could have been sought hereunder by such Indemnified Person,
unless such settlement (A) includes an unconditional written release of such
Indemnified Person, in form and substance reasonably satisfactory to such
Indemnified Person, from all liability on claims that are the subject matter of
such proceeding and (B) does not include any statement as to an admission of
fault, culpability or failure to act by or on behalf of such Indemnified Person.

            (d) If the indemnification provided for in the first and second
paragraphs of this Section 7 is for any reason unavailable to, or insufficient
to hold harmless, an Indemnified Person in respect of any losses, claims,
damages or liabilities referred to therein, then each Indemnifying Person under
such paragraphs, in lieu of indemnifying such Indemnified Person thereunder and
in order to provide for just and equitable contribution, shall contribute to the
amount paid or payable by such Indemnified Person as a result of such losses,
claims, damages or liabilities in such proportion as is appropriate to reflect
the relative fault of the Indemnifying Person or Persons on the one hand and the
Indemnified Person or Persons on the other in connection with the statements or
omissions or alleged statements or omissions that resulted in such losses,
claims, damages or liabilities (or actions in respect thereof) as well as

<PAGE>
                                      -24-

any other relevant equitable considerations. The relative fault of the parties
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information supplied by the Issuers on the
one hand or such Participant or such other Indemnified Person, as the case may
be, on the other, the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission, and any other
equitable considerations appropriate in the circumstances.

            (e) The parties agree that it would not be just and equitable if
contribution pursuant to this Section 7 were determined by PRO RATA allocation
(even if the Participants were treated as one entity for such purpose) or by any
other method of allocation that does not take account of the equitable
considerations referred to in the immediately preceding paragraph. The amount
paid or payable by an Indemnified Person as a result of the losses, claims,
damages, judgments, liabilities and expenses referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any reasonable legal or other expenses actually incurred by such
Indemnified Person in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this Section 7, in no event shall a
Participant be required to contribute any amount in excess of the amount by
which proceeds received by such Participant from sales of Registrable Notes or
Exchange Notes, as the case may be, exceeds the amount of any damages that such
Participant has otherwise been required to pay or has paid 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) Any losses, claims, damages, liabilities or expenses for which
an indemnified party is entitled to indemnification or contribution under this
Section 7 shall be paid by the Indemnifying Person to the Indemnified Person as
such losses, claims, damages, liabilities or expenses are incurred. The
indemnity and contribution agreements contained in this Section 7 and the
representations and warranties of the Issuers set forth in this Agreement shall
remain operative and in full force and effect, regardless of (i) any
investigation made by or on behalf of any Holder or any person who controls a
Holder, the Issuers, their directors, officers, employees or agents or any
person controlling an Issuer, and (ii) any termination of this Agreement.

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

8.    RULES 144 AND 144A

            Each of the Issuers covenants and agrees that it will file the
reports required to be filed by it under the Securities Act and the Exchange Act
and the rules and regulations adopted by the SEC thereunder in a timely manner
in accordance with the requirements of the Securities Act and the Exchange Act
and, for so long as any Registrable Notes remain outstanding, and if such Issuer
is not required to file such reports, such Issuer will, upon the request of any
Holder or beneficial owner of Registrable Notes, make available such information
of the type specified in Sections 13 and 15(d) of the Exchange Act. Each of the
Issuers further covenants and agrees, for so long as any Registrable Notes
remain outstanding, to make available to any Holder or beneficial owner of
Registrable Notes in connection with any sale thereof and any prospective
purchaser of such Registrable Notes from such Holder or beneficial owner the
information required by Rule 144A(d)(4) and 144(c) under the Securities Act in
order to permit resales of such Registrable Notes pursuant to Rule 144A and Rule
144(k).

9.    UNDERWRITTEN REGISTRATIONS

            If any of the Registrable Notes covered by any Shelf Registration
are to be sold in an underwritten offering, the investment banker or investment
bankers and manager or managers that will manage the offering will be selected
by the Holders of a majority in aggregate principal amount of such Registrable
Notes included in such offering and shall be reasonably acceptable to the
Issuers.

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

10.   MISCELLANEOUS

            (a) NO INCONSISTENT AGREEMENTS. The Issuers have not, as of the date
hereof, and the Issuers shall not, after the date of this Agreement, enter into
any agreement with respect to any of their securities that is inconsistent with
the rights granted to the Holders of Registrable Notes in this Agreement or
otherwise conflicts with the provisions hereof. The 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 Issuers' other issued and outstanding
securities under any such agreements. The Issuers will not enter into any
agreement with respect to any of their securities which will grant to any Person
piggy-back registration rights with respect to any Registration Statement.

<PAGE>
                                      -26-

            (b) ADJUSTMENTS AFFECTING REGISTRABLE NOTES. The Issuers shall not,
directly or indirectly, take any action with respect to the Registrable Notes as
a class that would adversely affect the ability of the Holders of Registrable
Notes to include such Registrable Notes in a registration undertaken pursuant to
this Agreement.

            (c) ADDITIONAL AMOUNTS OF NOTES. The Notes are limited in aggregate
principal amount to $270,000,000, of which $170,000,000 will be issued on the
date hereof. Additional amounts of Notes may be issued in one or more series
from time to time under the Indenture (collectively "ADDITIONAL NOTES") prior to
the filing of any Registration Statement. The Issuers shall provide the
registration rights set forth under this Agreement to the Initial Purchasers and
any subsequent holder or holders of such Additional Notes and notwithstanding
anything contained herein may include such Additional Notes in any Registration
Statement filed hereunder.

            (d) AMENDMENTS AND WAIVERS. The provisions of this Agreement may not
be amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given, otherwise than with the prior written
consent of (I) the Issuers and (II)(A) the Holders of not less than a majority
in aggregate principal amount of the then outstanding Registrable Notes and (B)
in circumstances that would adversely affect the Participating Broker-Dealers,
the Participating Broker-Dealers holding not less than a majority in aggregate
principal amount of the Exchange Notes held by all Participating Broker-Dealers;
provided, HOWEVER, that Section 7 and this Section 10(c) may not be amended,
modified or supplemented without the prior written consent of each Holder and
each Participating Broker-Dealer (including any person who was a Holder or
Participating Broker-Dealer of Registrable Notes or Exchange Notes, as the case
may be, disposed of pursuant to any Registration Statement) affected by any such
amendment, modification or supplement. Notwithstanding the foregoing, a waiver
or consent to depart from the provisions hereof with respect to a matter that
relates exclusively to the rights of Holders of Registrable Notes whose
securities are being sold pursuant to a Registration Statement and that does not
directly or indirectly affect, impair, limit or compromise the rights of other
Holders of Registrable Notes may be given by Holders of at least a majority in
aggregate principal amount of the Registrable Notes being sold pursuant to such
Registration Statement.

            (e) NOTICES. All notices and other communications (including,
without limitation, any notices or other communications to the Trustee) provided
for or permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, next-day air courier or facsimile:

RELATING TO THIS AGREEMENT.

            (j) SEVERABILITY. If any term, provision, covenant or restriction of
this Agreement is held by a court of competent jurisdiction to be invalid,
illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their best efforts to find and employ an alternative means to
achieve the same or substantially the same result as that contemplated by such
term, provision, covenant or restriction. It is hereby stipulated and declared
to be the intention of the parties that they would have executed the remaining
terms, provisions, covenants and restrictions without including any of such that
may be hereafter declared invalid, illegal, void or unenforceable.

            (k) SECURITIES HELD BY THE ISSUERS OR THEIR AFFILIATES. Whenever the
consent or approval of Holders of a specified percentage of Registrable Notes is
required hereunder, Registrable Notes held by the Issuers or their affiliates
(as such term is defined in Rule 405 under the Securities Act) shall not be
counted in determining whether such consent or approval was given by the Holders
of such required percentage.

            (l) THIRD-PARTY BENEFICIARIES. Holders of Registrable Notes and
Participating Broker-Dealers are intended third-party beneficiaries of this
Agreement, and this Agreement may be enforced by such Persons.

Time, or as soon as practicable thereafter, the former holder thereof shall be
entitled to receive from the Company in consideration for such cancellation an
amount in cash equal to the product of (x) the number of Company Common Shares
previously subject to such Option and (y) the excess, if any, of the Cash Merger
Consideration per share over the exercise price per share, if any, previously
subject to such Option (the "NET VALUE"), subject to withholding or other taxes
required by law to be withheld or (ii) in the event the holder thereof does not
consent to such cancellation, shall after the Effective Time represent solely
the right to receive the Cash Merger Consideration per share upon exercise
thereof; PROVIDED, HOWEVER, that with respect to the individuals listed on
SCHEDULE 3.3 (as such schedule may be amended by the mutual consent of Sub and
the Company (such consent not to be unreasonably withheld by Sub or the Company)
from time to time prior to the Effective Time; it being understood that it is
contemplated that additional employees of the Company and its Subsidiaries may
be added to such schedule and the aggregate Net Value set forth opposite the
name of any Person set forth on such schedule may be modified as agreed with
such Person), Options held by each such individual representing an aggregate Net
Value not less than the amount set forth opposite such person's name on SCHEDULE
3.3 shall be retained and shall not be cancelled.

      (b) Except as provided herein or as otherwise agreed by the parties, the
Stock Option Plans and any other plan, program or arrangement with any current
or former employee, officer, director or consultant providing for the issuance
or grant of any other interest in respect of the capital stock of the Company or
any Subsidiary, including the 1996 Non-Employee Director Compensation Program,
shall terminate as of the Effective Time, and the Company shall exercise its
reasonable best efforts to ensure that following the Effective Time, no current
or former employee, officer, director or consultant shall have any Option to
purchase Company Common Shares or any other equity interest in the Company under
any Stock Option Plan or any other Employee Plan maintained by the Company.

      (c) Prior to the Effective Time, the Board of Directors (or, if
appropriate, any committee administering the Stock Option Plans) shall adopt
such resolutions or take such actions as are necessary, subject, if necessary,
to obtaining consents of the holders of Options to the cancellation thereof in
exchange for the consideration set forth in Section 3.3(a)(i), to carry out the
terms of this SECTION 3.3.

      3.4 EXCHANGE OF CERTIFICATES; PAYMENT OF CASH MERGER CONSIDERATION.
          --------------------------------------------------------------

      (a) As of or promptly after the Effective Time, Sub will cause the
Surviving Corporation to deposit with a paying agent to be selected by Sub and
reasonably acceptable to the Company (the "EXCHANGE AGENT") for the benefit of
the holders of Company Common Shares, for payment in accordance with this
Article III, the funds necessary to pay the Cash Merger Consideration for each
share and certificates for Surviving Corporation Common Shares.

      (b) As soon as practicable after the Effective Time, (i) each holder of an
outstanding certificate or certificates which pursuant to SECTION 3.2(B)
represents the right to receive Surviving Corporation Common Shares, upon
surrender to the Exchange Agent of such

                                       10
<PAGE>

certificate or certificates and acceptance thereof by the Exchange Agent, shall
be entitled to a certificate or certificates representing the Series A Share
Consideration, into which the number of Series A Shares previously represented
by such certificate or certificates surrendered shall have been converted
pursuant to this Agreement and (ii) each holder of an outstanding certificate or
certificates which immediately prior to the Effective Time represented Company
Common Shares, upon surrender to the Exchange Agent of such certificate or
certificates and acceptance thereof by the Exchange Agent, shall be entitled to
receive in exchange therefor the Cash Merger Consideration multiplied by the
number of Company Common Shares formerly represented by such certificate. No
interest will be paid on or accrue on the Cash Merger Consideration or Series A
Share Consideration. The Exchange Agent shall accept such certificates upon
compliance with such reasonable terms and conditions as the Exchange Agent may
impose (with the consent of the Company not to be unreasonably withheld) to
effect an orderly exchange thereof in accordance with customary exchange
practices. After the Effective Time, there shall be no further transfer on the
records of the Company or its transfer agent of certificates formerly
representing Company Common Shares which have been converted, in whole or in
part, pursuant to this Agreement, into the right to receive cash, and if such
certificates are presented to the Company for transfer, they shall be canceled
against delivery of such cash. Until surrendered as contemplated by this SECTION
3.4(B), (i) each certificate formerly representing Series A Shares shall be
deemed at any time after the Effective Time to represent only the right to
receive upon such surrender a new certificate or certificates representing
Surviving Corporation Common Shares, as contemplated by SECTION 3.2(B), and (ii)
each certificate formerly representing Company Common Shares (other than the
Dissenting Shares) shall be deemed at any time after the Effective Time to
represent only the right to receive upon such surrender the Cash Merger
Consideration for each Company Common Share.

      (c) No dividends or other distributions with respect to Surviving
Corporation Common Shares with a record date after the Effective Time shall be
paid to the holder of any certificate formerly representing Series A Shares not
surrendered with respect to the Merger. Subject to applicable law, following
surrender of any such certificate, there shall be paid to the holder of such
certificate or certificates, without interest, at the appropriate payment date,
the proportionate amount of dividends or other distributions with a record date
after the Effective Time but prior to such surrender and a payment date
subsequent to such surrender payable with respect to such shares.

      (d) All cash paid upon the surrender for exchange of certificates formerly
representing Company Common Shares in accordance with the terms of this Article
III shall be deemed to have been paid in full satisfaction of all rights
pertaining to the shares exchanged for cash theretofore represented by such
certificates.

      (e) Any cash or Series A Share Consideration deposited with the Exchange
Agent pursuant to this SECTION 3.4 (the "EXCHANGE FUND") which remains
undistributed to the holders of the certificates formerly representing Company
Common Shares or Series A Shares one year after the Effective Time shall be
delivered to the Surviving Corporation at such time and any former holders of
Company Common Shares or Series A Shares prior to the Merger who have not
theretofore complied with this Article III shall thereafter look only to the
Surviving

                                       11
<PAGE>

Corporation and only as general unsecured creditors thereof for payment of their
claim for Cash Merger Consideration or Series A Share Consideration, if any.

      (f) None of Sub, the Company or the Exchange Agent shall be liable to any
Person in respect of any cash from the Exchange Fund delivered to a public
office pursuant to any applicable abandoned property, escheat or similar law. If
any certificates representing Company Common Shares shall not have been
surrendered prior to two years after the Effective Time (or immediately prior to
such earlier date on which any cash in respect of such certificate would
otherwise escheat to or become the property of any federal, state, local, or
municipal, foreign or other government or subdivision, branch, department or
agency thereof and any governmental or quasi-governmental authority of any
nature, including any court or other tribunal), any such cash in respect of such
certificate shall, to the extent permitted by applicable law, become the
property of the Surviving Corporation, free and clear of all claims or interest
of any Person previously entitled thereto.

      (g) In the event any certificate formerly representing Company Common
Shares or Series A Shares shall have been lost, stolen or destroyed, upon the
making of an affidavit of that fact by the Person claiming such certificate to
be lost, stolen or destroyed and, if required by the Surviving Corporation, the
posting by such Person of a bond in such reasonable amount as the Surviving
Corporation may direct as indemnity against any claim that may be made against
it with respect to such certificate, the Exchange Agent will issue or pay, as
the case may be, in exchange for such lost, stolen or destroyed certificate the
shares representing the Series A Share Consideration, and unpaid dividends and
distributions on shares representing the Series A Share Consideration
deliverable in respect thereof pursuant to this Agreement, or the Cash Merger
Consideration, as applicable.

      3.5 DISSENTING SHARES. Notwithstanding SECTION 3.2 hereof, Dissenting
Shares shall not be converted into a right to receive the Cash Merger
Consideration. The holders thereof shall be entitled only to such rights as are
granted by Sections 1701.84 and 1701.85 of the OCL. Each holder of Dissenting
Shares who becomes entitled to payment for such shares pursuant to Section
1701.85 of the OCL shall receive payment therefor from the Surviving Corporation
in accordance with the OCL; PROVIDED, HOWEVER, that (i) if any such holder of
Dissenting Shares shall have failed to establish his entitlement to relief as a
dissenting shareholder as provided in Section 1701.85 of the OCL, (ii) if any
such holder of Dissenting Shares shall have effectively withdrawn his demand for
relief as a dissenting shareholder with respect to such shares or lost his right
to relief as a dissenting shareholder and payment for his shares under Section
1701.85 of the OCL, or (iii) if neither any holder of Dissenting Shares nor the
Surviving Corporation shall have filed a complaint demanding a determination of
the value of all Dissenting Shares within the time provided in Section 1701.85
of the OCL, such holder shall forfeit the right to relief as a dissenting
shareholder with respect to such shares and each such share shall be treated as
if it had been converted, as of the Effective Time, into the right to receive
the Cash Merger Consideration, without interest thereon, from the Surviving
Corporation as provided in SECTION 3.2. The Company shall give Sub prompt notice
of any demands received by the Company for relief as a dissenting shareholder,
and Sub shall have the right to participate in all negotiations and proceedings
with respect to such demands. The Company shall not, except with the prior

                                       12
<PAGE>

written consent of Sub, make any payment with respect to, or settle or offer to
settle, any such demands.

has been duly authorized by all requisite corporate action. This Agreement has
been duly authorized, executed and delivered by the Company and is a legal,
valid and binding obligation of the Company, enforceable against the Company in

conveyance or similar laws in effect which affect the enforcement of creditors'
rights generally or (b) general principles of equity, whether considered in a
proceeding at law or in equity.

its Subsidiaries own, or have valid leasehold or license interests in, all

          ---------------

          (i)    Pension Plans
                 -------------

                  (A) The Company has hired an enrolled actuary in order to
evaluate the funded status of the Pension Plans subject to Title IV of ERISA
and, to the knowledge of the Company, the funding method used by such actuary in
connection with each Pension Plan which is subject to the minimum funding
requirements of ERISA is acceptable and the actuarial assumptions used by such
actuary in connection with funding each such plan are reasonable. As of the last
day of the last plan year of each Pension Plan and as of the Closing Date, there
are (and were) no material "unfunded benefit liabilities" as defined in Section
4001(a)(18) of ERISA (but excluding from the definition of "current value" of
"assets" of such Pension Plan, accrued but unpaid contributions) with respect to
any Pension Plan. Within the six years immediately preceding the Closing Date,
no "accumulated funding deficiency" (for which an excise tax is due or would be
due in the absence of a waiver) as defined in Section 412 of the Code or as
defined in Section 302(a)(2) of ERISA, whichever may apply, has been incurred
with respect to any Pension Plan with respect to any plan year, whether or not
waived. Neither the Company nor any ERISA Affiliate has failed to pay when due
any "required installment," within the meaning of Section 412(m) of the Code and
Section 302(e) of ERISA, whichever may apply, with respect to any Pension Plan.
Neither Company nor any ERISA Affiliate is subject to any lien imposed under
Section 412(n) of the Code or Section 302(f) of ERISA, whichever may apply, with
respect to any Pension Plan.

                  (B) Neither the Company nor any ERISA Affiliate is required to
provide security to a Pension Plan under Section 401(a)(29) of the Code.

                  (C) Each Pension Plan and each related trust agreement,
annuity contract or other funding instrument which covers or, with respect to
any Pension Plan subject to Title IV of ERISA, within the past six years, has
covered current or former employees, directors, officers or consultants of
Company is qualified and tax-exempt under the provisions of Code

                                       19
<PAGE>

Sections 401(a) (or 403(a), as appropriate) and 501(a) and nothing has occurred
during the period from its adoption to date that could materially affect such
qualification.

                  (D) The Company has paid all premiums (and interest charges
and penalties for late payment, if applicable) due the PBGC with respect to each
Pension Plan for each plan year thereof for which such premiums are required.
Neither Company nor any ERISA Affiliate has engaged in, or is a successor or
parent corporation to an entity that has engaged in, a transaction described in
Section 4069 of ERISA. Within the six years ending on the date of this
Agreement, (1) there has been no "reportable event" (as defined in Section
4043(c) of ERISA and the PBGC regulations under such Section) with respect to
any Pension Plan and neither Company nor any ERISA Affiliate is subject to
Section 4043(b) of ERISA and no analogous event under applicable foreign law and
(2) except as set forth on SECTION 4.15 of the Disclosure Letter, no filing has
been made by the Company or any ERISA Affiliate with the PBGC, and no proceeding
has been commenced by the PBGC, to terminate any Pension Plan. No condition
exists and no event has occurred that could constitute grounds for the
termination of any Pension Plan by the PBGC. Within the six years ending on the
date of this Agreement, neither the Company nor any ERISA Affiliate has, at any
time, (1) ceased operations at a facility so as to become subject to the
provisions of Section 4062(e) of ERISA or analogous foreign law, (2) withdrawn
as a substantial employer so as to become subject to the provisions of Section
4063 of ERISA or analogous foreign law, or (3) ceased making contributions to
any Pension Plan subject to Section 4064(a) of ERISA or analogous foreign law to
which Company or any ERISA Affiliate made contributions during the six years
prior to the Closing Date.

          (ii)    MULTIEMPLOYER PLANS

                  (A) Within the six years ending on the date of this Agreement,
neither the Company nor any ERISA Affiliate has, at any time, withdrawn from a
Multiemployer Plan in a "complete withdrawal" or a "partial withdrawal" as
defined in Sections 4203 and 4205 of ERISA, respectively, so as to result in a
liability, contingent or otherwise (including without limitation the obligations
pursuant to an agreement entered into in accordance with Section 4204 of ERISA),
of the Company or any ERISA Affiliate. Neither the Company nor any ERISA
Affiliate has engaged in, or is a successor or parent corporation to an entity
that has engaged in, a transaction described in Section 4212(c) of ERISA.

                  (B) All contributions required to be made by Company or any
ERISA Affiliate to each Multiemployer Plan have been made when due.

                  (C) If, as of the Closing Date, Company (and all ERISA
Affiliates) were to withdraw from all Multiemployer Plans to which it (or any of
them) has contributed or been obligated to contribute, it (and they) would incur
no material liabilities to such plans under Title IV of ERISA or analogous
foreign law.

                  (D) As of the date of this Agreement, to the best of the
Company's knowledge, with respect to each Multiemployer Plan: (1) no such
Multiemployer Plan has been terminated or has been in reorganization under ERISA
so as to result, directly or indirectly, in any liability, contingent or
otherwise, of the Company or any ERISA Affiliate under Title IV of

                                       20
<PAGE>

ERISA; (2) no proceeding has been initiated by any person (including the PBGC)
to terminate such Multiemployer Plan; (3) a "mass withdrawal," as defined in
PBGC Reg. Section 2640.7, with respect to such Multiemployer Plan has not
occurred; (4) the Company and the ERISA Affiliates have no reason to believe
that such Multiemployer Plan will be terminated or will be reorganized under
ERISA or that a "mass withdrawal," as defined in PBGC Reg. Section 2640.7, will
occur with respect to such Multiemployer Plan; and (5) the Company and the ERISA
Affiliates do not expect to withdraw in a "complete withdrawal" or "partial
withdrawal" from such Multiemployer Plan.

         (iii)    WELFARE PLANS

                  (A) Except as set forth in SECTION 4.15(B)(III)(A) of the
Disclosure Letter, none of the Company, any ERISA Affiliate or any Welfare Plan
has any present or future obligation to make any payment to, or with respect to
any present or former employee of the Company or any ERISA Affiliate pursuant
to, any retiree medical benefit plan, or other retiree Welfare Plan, and, to the
knowledge of the Company, no condition exists which would prevent Company from
amending or terminating any such benefit plan or Welfare Plan.

                  (B) Each Welfare Plan which covers current or former
employees, directors, officers or consultants of the Company or an ERISA
Affiliate and which is a "group health plan," as defined in Section 607(1) of
ERISA, has been operated, in all material respects, in compliance with
provisions of Part 6 of Title I, Subtitle B of ERISA and Section 4980B of the
Code at all times.

                  (C) Neither the Company nor any ERISA Affiliate has incurred
any liability with respect to any Welfare Plan that is a "multiemployer plan,"
as defined in Section 3(37) of ERISA, under the terms of such Welfare Plan, any
collective bargaining agreement or otherwise resulting from any cessation of
contributions, cessation of obligation to make contributions or other form of
withdrawal from such Welfare Plan.

            (iv) COMPLIANCE WITH LAW. Each Employee Plan presently complies and
has been maintained in compliance with its terms and with the requirements
prescribed by any and all statutes, orders, rules and regulations which are
applicable to such Employee Plan, including without limitation, ERISA and the
Code, and by its terms can be amended or terminated at any time. Through the
date of this Agreement, the Company has made all contributions and payments
required to be made by it with respect to each Employee Plan, including any
Foreign Plan (as defined below), or adequate accruals therefor have been
provided for and will be reflected in accordance with GAAP on the Financial
Statements provided to the Sub by the Company.

            (v) DEDUCTIBILITY OF PAYMENTS. There is no contract, agreement, plan
or arrangement covering any current or former employee, director, officer or
consultant of the Company (with respect to its relationship with such entities)
that, individually or collectively, provides for the payment by the Company of
any amount that is not deductible under Section 162(m) or 404 of the Code.

                                       21
<PAGE>

            (vi) FOREIGN PLANS. Each Employee Plan that covers any current or
former employee, director, officer or consultant of any Foreign Subsidiary or is
otherwise not subject to ERISA or the Code (each, a "FOREIGN PLAN") has been
maintained in substantial compliance with its terms and with the requirements
prescribed by any and all applicable statutes, orders, rules and regulations
(including without limitation any special provisions relating to the tax status
of contributions to, earnings of or distributions from such Plans where each
such Plan was intended to have such tax status) and has been maintained in good
standing with applicable regulatory authorities.

            (vii) FIDUCIARY DUTIES AND PROHIBITED TRANSACTIONS. Neither Company
nor any plan fiduciary of any Welfare Plan or Pension Plan which covers or, with
respect to any Pension Plan subject to Title IV of ERISA, within the past six
years, has covered current or former employees, directors, officers or
consultants of the Company or any ERISA Affiliate, has engaged in any
transaction in violation of Sections 404 or 406 of ERISA or any "prohibited
transaction," as defined in Section 4975(c)(1) of the Code, for which no
exemption exists under Section 408 of ERISA or Section 4975(c)(2) or (d) of the
Code, or has otherwise violated the provisions of Part 4 of Title I, Subtitle B
of ERISA. The Company has not knowingly participated in a violation of Part 4 of
Title I, Subtitle B of ERISA by any plan fiduciary of any Welfare Plan or
Pension Plan (or other employee benefit plan subject to ERISA) and has not been
assessed any civil penalty under Section 502(l) of ERISA.

            (viii) LITIGATION. As of the date of this Agreement, there is no
action, order, writ, injunction, judgment or decree outstanding or claim, suit,
litigation, proceeding, arbitral action, governmental audit or investigation

current or former employees, directors, officers or consultants of the Company.

            (x) INSURANCE CONTRACTS. To the best of the Company's knowledge,

holds as an asset of any Employee Plan any interest in any annuity contract,
guaranteed investment contract or any other investment or insurance contract
issued by an insurance company that is the subject of bankruptcy,
conservatorship or rehabilitation proceedings, the consequence of which would be
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on the Company.

            (xi) NO ACCELERATION OR CREATION OF RIGHTS. Except as set forth in
SECTION 4.15 of the Disclosure Letter, neither the execution and delivery of
this Agreement or other related agreements by the Company nor the consummation

discussions or negotiations with such a Third Party who has made a bona fide
Acquisition Proposal and/or (iii) taking any non-appealable, final action
ordered to be taken by the Company or its Subsidiaries by any court of competent
jurisdiction, but in each case referred to in the foregoing clauses (i) and
(ii), only to the extent that, in response to a bona fide Acquisition Proposal
that the Board of Directors of the Company shall have determined in good faith
is reasonably likely to result in a Superior Proposal (as defined in SECTION
8.1(A)(VI), the Board of Directors of the Company shall have concluded in good
faith after consultation with outside counsel that such action is required to
prevent the Board of Directors of the Company from breaching its fiduciary
duties to the shareholders of the Company under applicable law; PROVIDED,
FURTHER, that the Board of Directors of the Company shall not take any of the
foregoing actions referred to in clauses (i) and (ii) until after the Company

the foregoing, if, prior to the Shareholder Vote, the Board of Directors of the
Company receives a bona fide Acquisition Proposal and as a result thereof the
Board of Directors determines in good faith, after consultation with outside
counsel, that it is necessary to do so in order to comply with their fiduciary
obligations, the Board of Directors of the Company may withdraw or modify its
approval or recommendation of the Merger and this Agreement. The Company shall
immediately cease and order its advisors, agents and other intermediaries to
cease any and all existing activities, discussions or negotiations with any
parties conducted heretofore with respect to any of the foregoing; PROVIDED that
the Company shall be responsible for any such advisor, agent or other
intermediary failing to cease such activities, discussions and negotiations.
Nothing contained in this SECTION 6.4 shall prohibit the Company from taking or
disclosing to its shareholders a position contemplated by Rule 14e-2(a) under
the Exchange Act or from making any disclosure to its shareholders if, in the
good faith judgment of the Board of Directors of the Company, after consultation
with outside counsel, failure to so disclose would be in violation of its
obligations under Applicable Law.

       (b) If a Payment Event (as hereinafter defined) occurs, the Company shall
pay to Sub, within one business day following such Payment Event, a fee of
$6,000,000. "PAYMENT EVENT" means (1) the termination of this Agreement pursuant
to SECTION 8.1(A)(V); (2) the termination of this Agreement pursuant to SECTION
8.1(A)(VI); or (3) the occurrence of any of the following events if this
Agreement shall have been terminated (i) by Sub pursuant to SECTION 8.1(A)(III)
due to a failure of the condition set forth in SECTION 7.1(A) to be satisfied or
(ii) by the Company pursuant to SECTION 8.1(A)(III) due to a failure of the
condition set forth in SECTION 7.1(A) to be satisfied: (A) prior to the
Shareholder Vote, (x) any Third Party shall have become the beneficial owner of
more than 20% of the outstanding Company Common Shares or (y) any Third Party
shall have made, or proposed, communicated or disclosed in a manner which is or
otherwise becomes public a bona fide intention to make an Acquisition Proposal
(including by making such an Acquisition Proposal) and (B) on or prior to the
date that is within 12 months of the termination of this Agreement, the Company
either consummates with a Third Party a transaction the proposal of which would
otherwise qualify as an Acquisition Proposal under SECTION 6.4(A) or enters into
a definitive agreement with a Third Party with respect to a transaction the
proposal of which would otherwise qualify as an Acquisition Proposal under
SECTION 6.4(A) and such transaction is consummated within six months of the date
of such definitive agreement (whether or not such Third Party is the Third Party
referred to in clause (x) above) (it being understood that for purposes of this
clause (B) the phrase "50%" is substituted

                                       34
<PAGE>

for the phrase "20%" in the definition of Acquisition Proposal and that in
determining whether such 50% threshold shall have been satisfied, all Assets and
Equity Securities acquired by the Third Party that consummates the Acquisition
Proposal prior to the termination of this Agreement shall be included).

       (c) Upon termination of this Agreement (1) pursuant to SECTION 8.1(A)(V),
8.1(A)(VI) or 8.1(A)(VII), (2) by Sub pursuant to SECTION 8.1(A)(III) due to a
failure of a condition set forth in SECTION 7.1(A) or SECTIONS 7.3(A), (E) or
(F) to be satisfied or (3) by the Company pursuant to SECTION 8.1(A)(III) due to
a failure of the condition set forth in SECTION 7.1(A) to be satisfied, the
Company shall reimburse Sub and its Affiliates not later than two business days
after submission of reasonable documentation thereof for all of their documented
out-of-pocket fees and expenses (including, without limitation, the reasonable
fees and expenses for their counsel and investment banking fees), actually
incurred by any of them or on their behalf in connection with this Agreement and
the transactions contemplated hereby and the arrangement of, obtaining the
commitment to provide or obtaining the Financing for transactions contemplated
by this Agreement (including any reasonable fees payable to the entities
providing for Financing and their respective counsel); PROVIDED that the
aggregate amount payable pursuant to this SECTION 6.4(D) shall not exceed
$1,250,000.

       (d) The Company shall (i) promptly notify Sub (orally and in writing) if
any offer is made, any discussions or negotiations are sought to be initiated,

respect to any Acquisition Proposal, (ii) promptly notify Sub of the material
terms of any proposal which it may receive in respect of any such Acquisition
Proposal, including, without limitation, the identity of the prospective
purchaser or soliciting party, (iii) promptly provide Sub with a copy of any
such offer, if written, or a written summary (in reasonable detail) of such
offer, if not in writing, and (iv) keep Sub informed of the status of such offer
and the offeror's efforts and activities with respect thereto (including,
without limitation, the response of the Board of Directors with respect
thereto).

       6.5 MEETING OF SHAREHOLDERS. The Company shall take all action necessary
in accordance with applicable law and its articles of incorporation and code of
regulations, including the timely mailing of the Proxy Statement, to convene the
Special Meeting of its Shareholders as promptly as practicable to consider and
vote upon the adoption of this Agreement and the approval of the transactions
contemplated hereby. The Board of Directors of the Company shall recommend such
adoption and approval, shall not withdraw or modify such recommendation and
shall take all lawful action to solicit such adoption and approval; PROVIDED
that the Board of Directors of the Company may fail to make or withdraw or
modify such recommendation, but only to the extent that the Board of Directors
of the Company shall have concluded in good faith after consultation with
outside counsel that such action is required to prevent the Board of Directors
of the Company from breaching its fiduciary duties to the shareholders of the
Company under applicable law. The Company will use its reasonable best efforts
to hold such meeting as soon as reasonably practicable after the date hereof.

       6.6 Proxy Statement.
           ---------------

       (a) Sub and the Company shall cooperate and prepare, and the Company
shall file with the SEC as soon as reasonably practicable, a proxy statement
with respect to the Special Meeting of the Shareholders in connection with the
Merger (the "PROXY STATEMENT"), respond to comments of the staff of the SEC,
clear the Proxy Statement with the staff of the SEC and promptly thereafter mail
the Proxy Statement to all holders of record of Company Common Shares. The
Company shall comply in all material respects with the requirements of the
Exchange Act and the Securities Act and the rules and regulations of the SEC
thereunder applicable to the Proxy Statement and the solicitation of proxies for
the Special Meeting (including any requirement to amend or supplement the Proxy
Statement) and each party shall furnish to the other such information relating

       (b) No amendment or supplement to the Proxy Statement shall be made by
the Company to which Sub reasonably objects. Prior to filing any amendment or
supplement to the Proxy Statement, the Company shall give Sub reasonable advance
notice and a copy of the proposed amendment or supplement. The Company shall
advise Sub of any request by the SEC for amendment of the Proxy Statement or
comments thereon and responses thereto or requests by the SEC for additional

       6.7 Director and Officer Liability.
           ------------------------------

       (a) For a period of six years after the Effective Time, Sub will cause
the Surviving Corporation to indemnify and hold harmless the present and former
officers and directors of the Company in respect of acts or omissions occurring
prior to the Effective Time to the extent provided under the Company's articles
of incorporation and code of regulations in effect on the date hereof; PROVIDED
that such indemnification shall be subject to any limitation imposed from time
to time under applicable law. To the maximum extent permitted by the OCL, such
indemnification shall be mandatory rather than permissive and the Surviving
Corporation shall advance expenses in connection with such indemnification. The
articles of incorporation and the code of regulations of the Surviving
Corporation shall contain provisions substantially similar in terms of the
rights granted to the provisions with respect to indemnification and insurance
set forth in the Company's articles of incorporation, which provisions shall not
be amended in any manner that would adversely affect the rights under those code
of regulations of the Company's employees, agents, directors or officers for
acts or omissions on or prior to the Effective Time, except if such amendment is
required by law. For a period of six years after the Effective Time, Sub will
cause the Surviving Corporation to use its reasonable best efforts to provide
officers' and directors' liability insurance in respect of acts or omissions
occurring prior to the Effective Time covering each such Person currently
covered by the Company's officers' and directors' liability insurance policy on
terms with respect to coverage and amount no less favorable than those of such
policy in effect on the date hereof, PROVIDED that in satisfying its obligation
under this SECTION 6.7, Sub shall not be obligated to cause the Surviving
Corporation to pay premiums in excess of 200% of the amount per annum the
Company paid in its last full fiscal year, which amount has been disclosed to
Sub.

                                       36
<PAGE>

(b) In furtherance of and not in limitation of the preceding paragraph, Sub
agrees that the officers and directors of the Company that are defendants in all
litigation commenced by shareholders of the Company with respect to (x) the
performance of their duties as such officers and/or directors under federal or
state law (including litigation under federal and state securities laws) and (y)
the Merger, including, without limitation, any and all such litigation commenced
on or after the date of this Agreement (the "SUBJECT LITIGATION") shall be
entitled to be represented, at the reasonable expense of the Company, in the
Subject Litigation by one counsel (and Ohio counsel if appropriate and one local
counsel in each jurisdiction in which a case is pending) each of which such
counsel shall be selected by a plurality of such director defendants; PROVIDED
that the Company shall not be liable for any settlement effected without its
prior written consent (which consent shall not be unreasonably withheld) and
that a condition to the indemnification payments provided in SECTION 6.8(A)
shall be that such officer/director defendant not have settled any Subject
Litigation without the consent of the Company (such consent not to be
unreasonably withheld) and, prior to the Closing, Sub; and PROVIDED FURTHER that
neither Sub nor the Company shall have any obligation hereunder to any
officer/director defendant when and if a court of competent jurisdiction shall
ultimately determine, and such determination shall have become final and
non-appealable, that indemnification of such officer/director defendant in the
manner contemplated hereby is prohibited by applicable law.

       (c) In the event the Surviving Corporation or any of its successors or
assigns (i) consolidates with or merges into any other Person and shall not be
the continuing or surviving corporation or entity of such consolidation or
merger or (ii) transfers all or substantially all of its properties and assets
to any Person, then, and in each such case, proper provisions shall be made so
that the successors and assigns of the Surviving Corporation shall assume its
obligations set forth in this SECTION 6.7.

       6.8 NOTICES OF CERTAIN EVENTS. Each of the Company and Sub shall promptly
notify the other of:

       (a) any notice or other communication from any Person alleging that the
consent of such Person is or may be required in connection with the transactions
contemplated by this Agreement;

       (b) any notice or other communication from any governmental or regulatory
agency or authority in connection with the transactions contemplated by this
Agreement; and

       (c) any Actions commenced or, to its knowledge, threatened, against the
Company or any of its Subsidiaries which, if pending on the date of this
Agreement, would have been required to have been disclosed pursuant to SECTION
4.11 or against the Company or any of its Subsidiaries or Sub which relate to
the consummation of the transactions contemplated by this Agreement.

       6.9 SUB NOTICE. Sub shall promptly advise the Company of any Material

comparison from the prior fiscal year. Such interim financial statements shall

Series A Shares having rights, preferences and designations set forth on
SCHEDULE 6.1(C) and (ii) take all such actions as may be necessary to exchange
each Company Common Share held by the Persons listed on SCHEDULE A that is set
forth opposite their respective names in SCHEDULE A (as such schedule may be
amended by the mutual consent of Sub and the Company (such consent not to be
unreasonably withheld by Sub or the Company) from time to time prior to the
Effective Time; it being understood that it is contemplated that additional
employees of the Company and its Subsidiaries may be added to such schedule and
the number of Preferred Shares set forth opposite the name of any Person set
forth on such schedule may be modified as agreed with such Person), for one
Series A Share and complete such exchange, in each case, pursuant to
documentation reasonably acceptable in form and substance to Sub, which
documentation shall provide, in any event, for adoption of this Agreement by
each such Person to the extent required by, and in accordance with, the OCL.

       6.13 BENEFIT ARRANGEMENTS. For a period of one year following the
Effective Time, Sub shall cause the Surviving Corporation (or in the case of
transfer of all the assets and business of the Surviving Corporation, its
successors and assigns) to maintain employee benefit plans (except stock option,
restricted stock, stock purchase or other equity based programs, plans and
arrangements) that are no less favorable in the aggregate than the Benefit
Arrangements, Pension Plans, Multiemployer Plans and Welfare Plans (except stock
option, restricted stock, stock purchase or other equity based programs, plans
and arrangements) in effect on the date of this Agreement.

       8.4 ENTIRE AGREEMENT; WAIVERS. This Agreement, together with all exhibits
and schedules hereto (including, without limitation, the Disclosure Letter), and
the other agreements referred to herein, constitute the entire agreement among
the parties pertaining to the subject matter hereof and supersedes all prior
agreements, understandings, negotiations and discussions, whether oral or
written, of the parties, other than the Confidentiality Letter. No waiver of any
of the provisions of this Agreement shall be deemed or shall constitute a waiver
of any other provision hereof (whether or not similar), nor shall such waiver
constitute a continuing waiver

                                       43
<PAGE>

unless otherwise expressly provided. The Confidentiality Letter shall terminate
at the Effective Time.

       8.5 MULTIPLE COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

       8.6 INVALIDITY. In the event that any one or more of the provisions
contained in this Agreement or in any other instrument referred to herein,
shall, for any reason, be held to be invalid, illegal or unenforceable in any
respect, then to the maximum extent permitted by law, such invalidity,
illegality or unenforceability shall not affect any other provision of this
Agreement or any other such instrument.

       8.7 TITLES. The titles, captions or headings of the Articles and Sections
herein are inserted for convenience of reference only and are not intended to be
a part of or to affect the meaning or interpretation of this Agreement.

       8.8 FEES AND EXPENSES. Except as provided in SECTION 6.4 hereof, all
costs and expenses incurred in connection with this Agreement shall be paid by
the party incurring such cost or expense. Notwithstanding the foregoing, a party
in breach of this Agreement shall, on demand, indemnify and hold harmless the
other party for and against all reasonable out-of-pocket expenses, including
legal fees, incurred by such other party by reason of the enforcement and
protection of its rights under this Agreement. The payment of such expenses is
in addition to any other relief to which such other party may be entitled.

       8.9 CUMULATIVE REMEDIES. All rights and remedies of either party hereto
are cumulative of each other and of every other right or remedy such party may
otherwise have at law or in equity, and the exercise of one or more rights or
remedies shall not prejudice or impair the concurrent or subsequent exercise of
other rights or remedies.

       8.10 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF OHIO, REGARDLESS OF THE LAWS THAT
MIGHT OTHERWISE GOVERN UNDER APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS.

       8.11 AMENDMENT. This Agreement may be amended by the parties hereto at
any time before or after approval of matters presented in connection with the
Merger by the shareholders of the Company, but after any such shareholder
approval, no amendment shall be made which by law requires the further approval
of shareholders without obtaining such further approval. This Agreement may not
be amended except by an instrument in writing signed on behalf of each of the
parties hereto.

       8.12 PUBLIC ANNOUNCEMENTS. Neither Sub or its Affiliates, on the one
hand, nor the Company, on the other hand, will issue any press release or public
statement with respect to the transactions contemplated by this Agreement,
including the Merger, without the other party's prior consent (such consent not
to be unreasonably withheld), except as may be required by Applicable Law, court
process or the requirements of the NYSE. In addition to the foregoing,

                                       44
<PAGE>

Sub or its Affiliates and the Company will consult with each other before
issuing, and provide each other the opportunity to review and comment upon, any
such press release or other public statements with respect to such transactions.
The parties agree that the initial press release or releases to be issued with
respect to the transactions contemplated by this Agreement shall be mutually
agreed upon prior to the issuance thereof.

       8.13 ENFORCEMENT OF AGREEMENT. The parties hereto agree that irreparable
damage would occur in the event that any of the provisions of this Agreement was
not performed in accordance with its specific terms or was otherwise breached.
It is accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions hereof, this being in addition to any other remedy to
which they are entitled at law or in equity.

       8.14 NON-SURVIVAL OF REPRESENTATIONS, WARRANTIES. The representations and
warranties in this Agreement or in any instrument delivered pursuant to this
Agreement shall terminate at the Effective Time.

                                 SCHEDULE 6.1(C)
                           PREFERRED SHARE DESIGNATION

       C. Series a Preferred Shares.
          -------------------------

         1. DESIGNATION. A total of 300,000 of the Corporation's authorized and
unissued Preferred Shares shall be designated as a series known as Series A
Preferred Shares, without par value (the "Series A Preferred Shares").

         The express terms of the Series A Preferred Shares shall be as follows:

         2. VOTING. Except as otherwise provided by law, the holders of Series A
Preferred Shares shall have no voting rights.

         3. DIVIDENDS. The holders of Series A Preferred Shares shall be
entitled to receive dividends out of funds legally available therefor at such
times and in such amounts as the directors may determine in their sole
discretion; provided, however, that no such dividend may be declared or paid on
any Series A Preferred Share unless at the same time a dividend is declared or
paid on all outstanding Common Shares and vice versa, with holders of Series A
Preferred Shares and Common Shares sharing in any such dividends as if they
constituted a single class of stock. Each Series A Preferred Share shall entitle
the holder thereof to receive dividends equal to the dividends payable with
respect to one Common Share. The right to dividends on the Series A Preferred
Shares shall not be cumulative, and no right shall accrue to holders of Series A
Preferred Shares by reason of the fact that dividends on said shares are not
declared in any prior period.

         4. LIQUIDATION PREFERENCE. Upon any liquidation, dissolution or winding
up of the Corporation and its subsidiaries, whether voluntary or involuntary (a
"Liquidation Event"), each holder of an outstanding Series A Preferred Share
shall be entitled to be paid out of the assets of the Corporation available for
distribution to shareholders, whether such assets are capital, surplus or
earnings, and before any amount shall be paid or distributed to the holders of
Common Shares or of any other shares ranking on liquidation junior to the Series
A Preferred Shares, an amount in cash equal to any declared but unpaid dividends
to which such holder of outstanding Series A Preferred Shares is then entitled
pursuant to Section 3 (the "Liquidation Preference Amount"); provided, however,
that if, upon any Liquidation Event, the amounts payable with respect to the
Liquidation Preference Amount are not paid in full, the holders of the Series A
Preferred Shares shall share ratably in any distribution of assets in proportion
to the full respective preferential amounts to which they are entitled.

         5. NO REISSUANCE OF SERIES A PREFERRED SHARES. No Series A Preferred
Shares acquired by the Corporation for or by any reason shall be reissued, and
all such shares shall be canceled, retired and eliminated from the Preferred
Shares which the Corporation shall be authorized to issue.

         6. CONTRACTUAL RIGHTS OF HOLDERS. The various provisions set forth
herein for the benefit of the holders of the Series A Preferred Shares shall be
deemed contract rights enforceable by them, including without limitation, one or
more actions for specific performance.

<PAGE>

         7. NO PRE-EMPTIVE RIGHTS. The holders of Series A Preferred Shares
shall not have any preemptive rights.

         8. CONVERSION. Upon the filing of the certificate of merger, or such
later time as specified therein, as contemplated by the Agreement and Plan of
Merger between Dayton Superior Corporation and Stone Acquisition Corp., dated as
of January 19, 2000 (the "Merger Agreement"), each Series A Preferred Share
shall by virtue of the merger contemplated by the Merger Agreement (the
"Merger") and without any action on the part of the holder thereof,
automatically be cancelled and converted into the right to receive one common
share, without par value, of the Company (as in existence immediately following
the Merger) upon surrender of the certificate formerly representing the Series A
Preferred Share.

                                 SCHEDULE 7.3(F)
                                  INDEBTEDNESS

Total indebtedness for borrowed money (long and short term) of the Company and
its Subsidiaries as of the Effective Time shall not exceed:

(1)......$149.5 million, less

(2)      the aggregate amount of all prepayment penalties and fees associated
         with the repayment of the Company's existing credit facilities, less

(3)      an amount equal to $21,250,000 minus the aggregate principal amount of
         Debentures outstanding and held by Persons other than the Company and
         its Affiliates as of the Effective Time, less

(4)      the aggregate amount to which the holders of the Debentures would be
         entitled to receive following the Effective Time upon conversion
         thereof (assuming for the purposes of this clause that the aggregate
         principal amount of Debentures outstanding immediately following the
         Effective Time is $21,250,000 and that all such Debentures are
         converted immediately following the Effective Time) minus $21,250,000;
         plus

(5)      to the extent that in connection with the EFCO V. SYMONS ET. AL matter,
         Symons Corporation is required to pay damages in excess of $1.0
         million, an amount equal to the lesser of (a) the amount of damages
         Symons Corporation is required to pay minus $1.0 million and (b) $14.0
         million; PROVIDED that if the Company and its Subsidiaries have not
         complied in all respects with Section 6.3(f) of the Agreement, this
         clause (3) shall be of no force or effect and the amount for purposes
         of Section 7.3(g) of the Agreement and this Schedule 7.3(g) shall be
         equal to the amount determined pursuant to clauses (1), (2), (3) and
         (4) of this Schedule 7.3(g).
