benefit of the Holders, at the Company's cost, (A) prepare and, as soon as
practicable but not later than 60 days following the Closing Date, file with the
SEC an Exchange Offer Registration Statement on an appropriate form under the
1933 Act with respect to a proposed Exchange Offer and the issuance and delivery
to the Holders, in exchange for the Registrable Securities (other than Private

their reasonable best efforts to cause the Exchange Offer Registration Statement
to be declared effective under the 1933 Act within 150 days of the Closing Date,
(C) use their reasonable best efforts to keep the Exchange Offer Registration
Statement effective until the closing of the Exchange Offer and (D) use their
reasonable best efforts to cause the Exchange Offer to be consummated not later
than 180 days following the Closing Date. The Exchange Securities will be issued
under the Indenture. Upon the effectiveness of the Exchange Offer Registration
Statement, the Company and the Guarantors shall promptly commence the Exchange
Offer, it being the objective of such Exchange Offer to enable each Holder
eligible and electing to exchange Registrable Securities for Exchange Securities
(assuming that such Holder (a) is not an affiliate of the Company within the
meaning of Rule 405 under the 1933 Act, (b) is not a broker-dealer tendering
Registrable Securities acquired directly from the Company for its own account,
(c) acquired the Registrable Securities in the ordinary course of such Holder's
business and (d) has no arrangements or understandings with any Person to
participate in the Exchange Offer for the purpose of distributing the Exchange
Securities) to transfer such Exchange Securities from and after their receipt
without any limitations or restrictions under the 1933 Act or under state
securities or blue sky laws.

         In connection with the Exchange Offer, the Company shall:

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

                  (b) keep the Exchange Offer open for acceptance for a period
         of not less than 30 calendar days after the date notice thereof is
         mailed to the Holders (or longer if required by applicable law) (such
         period referred to herein as the "Exchange Period");

                  (c) utilize the services of the Depositary for the Exchange
         Offer;

                  (d) permit Holders to withdraw tendered Registrable Securities
         at any time prior to 5:00 p.m. (Eastern Time) on the last business day
         of the Exchange Period, by sending to the institution specified in the
         notice a telegram, telex, facsimile transmission or letter setting
         forth the name of such Holder, the principal amount of Registrable
         Securities delivered for exchange, and a statement that such Holder is
         withdrawing such Holder's election to have such Securities exchanged;

                  (e) notify each Holder that any Registrable Security not
         tendered will remain outstanding and continue to accrue interest, but
         will not retain any rights under this Agreement (except in the case of
         the Initial Purchasers and Participating Broker-Dealers as provided
         herein); and


                                      -4-
   5

                  (f) otherwise comply in all respects with all applicable laws
         relating to the Exchange Offer.

         If, prior to consummation of the Exchange Offer, the Initial Purchasers
hold any Securities acquired by them and having the status of an unsold
allotment in the initial distribution, the Company and the Guarantors upon the
request of any Initial Purchaser shall, simultaneously with the delivery of the
Exchange Securities in the Exchange Offer, issue and deliver to such Initial
Purchaser in exchange (the "Private Exchange") for the Securities held by such
Initial Purchaser, a like principal amount of debt securities of the Company and
related guarantees by the Guarantors that are identical (except that such
securities shall bear appropriate transfer restrictions) to the Exchange
Securities (the "Private Exchange Securities").

         The Exchange Securities and the Private Exchange Securities 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 Trust Indenture Act of 1939, as amended (the "TIA"), or is exempt from such
qualification and shall provide that the Exchange Securities shall not be
subject to the transfer restrictions applicable to the Registrable Securities
set forth in the Indenture but that the Private Exchange Securities shall be
subject to such transfer restrictions. The Indenture or such indenture shall
provide that the Exchange Securities, the Private Exchange Securities and the
Securities shall vote and consent together on all matters as one class and that
none of the Exchange Securities, the Private Exchange Securities or the
Securities will have the right to vote or consent as a separate class on any
matter. The Private Exchange Securities shall be of the same series as and the
Company shall use all commercially reasonable efforts to have the Private
Exchange Securities bear the same CUSIP number as the Exchange Securities. The
Company shall not have any liability under this Agreement solely as a result of
such Private Exchange Securities not bearing the same CUSIP number as the
Exchange Securities.

         As soon as practicable after the close of the Exchange Offer and/or the
Private Exchange, as the case may be, the Company and the Guarantors shall:

                  (i) accept for exchange all Registrable Securities duly
         tendered and not validly withdrawn pursuant to the Exchange Offer in
         accordance with the terms of the Exchange Offer Registration Statement
         and the letter of transmittal which shall be an exhibit thereto;

                 (ii) accept for exchange all Securities properly tendered
         pursuant to the Private Exchange;

                  (iii) deliver to the Trustee for cancellation all Registrable
         Securities so accepted for exchange; and

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

         Interest on each Exchange Security and Private Exchange Security will
accrue from the last date on which interest was paid on the Registrable
Securities surrendered in exchange therefor or, if no interest has been paid on
the Registrable Securities, from the date of original issuance. The Exchange
Offer and the Private Exchange shall not be subject to any conditions, other
than (i) that the Exchange Offer or the Private Exchange, or the making of any
exchange by a Holder, does not violate applicable law or any applicable
interpretation of the staff of the SEC, (ii) the due tendering of Registrable
Securities in accordance with the Exchange Offer and the Private Exchange, (iii)
that each Holder of Registrable Securities exchanged in the Exchange Offer shall
have represented that all Exchange Securities to be received by it shall be
acquired in the ordinary course of its business and that at the time of the
consummation of the Exchange Offer it shall have no arrangement or understanding


                                      -5-
   6

with any person to participate in the distribution (within the meaning of the
1933 Act) of the Exchange Securities and shall have made such other
representations as may be reasonably necessary under applicable SEC rules,
regulations or interpretations to render the use of Form S-4 or other
appropriate form under the 1933 Act available and (iv) that no action or
proceeding shall have been instituted or threatened in any court or by or before
any governmental agency with respect to the Exchange Offer or the Private
Exchange which, in the Company's judgment, would reasonably be expected to
impair the ability of the Company to proceed with the Exchange Offer or the
Private Exchange. The Company shall inform the Initial Purchasers of the names
and addresses of the Holders to whom the Exchange Offer is made, and the Initial
Purchasers shall have the right to contact such Holders and otherwise facilitate
the tender of Registrable Securities in the Exchange Offer.

         2.2 Shelf Registration. (i) If, because of any changes in law, SEC
rules or regulations or applicable interpretations thereof by the staff of the
SEC, the Company is not permitted to effect the Exchange Offer as contemplated
by Section 2.1 hereof, (ii) if for any other reason the Exchange Offer
Registration Statement is not declared effective within 150 days following the
original issue of the Registrable Securities or the Exchange Offer is not
consummated within 180 days after the original issue of the Registrable
Securities, (iii) upon the request of any of the Initial Purchasers or (iv) if a
Holder is not permitted to participate in the Exchange Offer or does not receive
fully tradeable Exchange Securities pursuant to the Exchange Offer, then in case
of each of clauses (i) through (iv) the Company and the Guarantors shall, at the
Company's cost:

                  (a) As promptly as practicable, file with the SEC, and
         thereafter shall use their reasonable best efforts to cause to be
         declared effective as promptly as practicable but no later than 150
         days after the date the obligation to file the Shelf Registration
         Statement arises, a Shelf Registration Statement relating to the offer
         and sale of the Registrable Securities by the Holders from time to time
         in accordance with the methods of distribution elected by the Majority
         Holders participating in the Shelf Registration and set forth in such
         Shelf Registration Statement.

                  (b) Use their reasonable best efforts to keep the Shelf
         Registration Statement continuously effective in order to permit the
         Prospectus forming part thereof to be usable by Holders for a period of
         two years from the date the Shelf Registration Statement is declared
         effective by the SEC, or for such shorter period that will terminate
         when all Registrable Securities covered by the Shelf Registration
         Statement have been sold pursuant to the Shelf Registration Statement
         or cease to be outstanding or otherwise cease to be Registrable
         Securities (the "Effectiveness Period"); provided, however, that the
         Effectiveness Period in respect of the Shelf Registration Statement
         shall be extended to the extent required to permit dealers to comply
         with the applicable prospectus delivery requirements of Rule 174 under
         the 1933 Act and as otherwise provided herein; and provided, further,
         that the Company and the Guarantors shall not be obligated to keep the
         Shelf Registration Statement effective or to permit the use of any
         Prospectus forming a part of the Shelf Registration Statement if (A)
         the Company determines, in its reasonable judgment, upon advice of
         counsel, that the continued effectiveness and use of the Shelf
         Registration Statement would (x) require the disclosure of material
         information which the Company has a bona fide business reason for
         preserving as confidential, or (y) interfere with any financing,
         acquisition, corporate reorganization or other material transaction
         involving the Company or any of its subsidiaries, and provided,
         further, that the failure to keep the Shelf Registration Statement
         effective and usable for offers and sales of Registrable Securities for
         such reasons shall last no longer than an aggregate of 30 days in any
         consecutive twelve-month period (whereafter a Registration Default, as
         defined in Section 2.5, shall occur), and (B) the Company promptly
         thereafter complies with the requirements of Section 3(k) hereof, if
         applicable (any such period during which the Company is excused from
         keeping the Shelf Registration Statement effective and usable for
         offers and sales of Registrable Securities is referred to herein as a
         "Suspension Period", and a Suspension Period shall commence on and
         include the date that the Company gives notice to the Holders that the
         Shelf Registration Statement is no longer effective or the prospectus
         included therein is no longer usable for offers and sales of
         Registrable Securities as a result of the foregoing provisions and
         shall end on the earlier to occur of the date


                                      -6-
   7

         on which each seller of Registrable Securities covered by the Shelf
         Registration Statement either receives the copies of the supplemented
         or amended prospectus contemplated by Section 3(k) hereof or is advised
         in writing by the Company that use of the prospectus may be resumed);
         and

                  (c) use their reasonable best efforts to ensure that (i) any
         Shelf Registration Statement and any amendment thereto and any
         Prospectus forming part thereof and any supplement thereto complies in
         all material respects with the 1933 Act and the rules and regulations
         thereunder, (ii) any Shelf Registration Statement and any amendment
         thereto does not, when it becomes effective, 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 not
         misleading and (iii) subject to Section 2(b) above, any Prospectus
         forming part of any Shelf Registration Statement, and any supplement to
         such Prospectus (as amended or supplemented from time to time), does
         not include an untrue statement of a material fact or omit to state a
         material fact necessary in order to make the statements, in light of
         the circumstances under which they were made, not misleading.

         The Company shall not permit any securities other than Registrable
Securities to be included in the Shelf Registration Statement. The Company and
the Guarantors further agree, if necessary, to supplement or amend the Shelf
Registration Statement, as required by Section 3(b) below, and to furnish to the
Holders of Registrable Securities copies of any such supplement or amendment
promptly after its being used or filed with the SEC.

         2.3 Expenses. The Company shall pay all Registration Expenses in
connection with the registration pursuant to Section 2.1 or 2.2. Each Holder
shall pay all underwriting discounts and commissions and transfer taxes, if any,
relating to the sale or disposition of such Holder's Registrable Securities
pursuant to the Shelf Registration Statement.

         2.4 Effectiveness. (a) The Company and the Guarantors will be deemed
not to have used their reasonable best efforts to cause the Exchange Offer
Registration Statement or the Shelf Registration Statement, as the case may be,
to become, or to remain, effective during the requisite period if they
voluntarily take any action that would, or omits to take any action which
omission would, result in any such Registration Statement not being declared
effective or in the Holders of Registrable Securities covered thereby not being
able to exchange or offer and sell such Registrable Securities during that
period as and to the extent contemplated hereby, unless such action is required
by applicable law.

         (b) An Exchange Offer Registration Statement pursuant to Section 2.1
hereof or a Shelf Registration Statement pursuant to Section 2.2 hereof will not
be deemed to have become effective unless it has been declared effective by the
SEC; provided, however, that if, after it has been declared effective, the
offering of Registrable Securities pursuant to an Exchange Offer Registration
Statement or a Shelf Registration Statement is interfered with by any stop
order, injunction or other order or requirement of the SEC or any other
governmental agency or court, such Registration Statement will be deemed not to
have become effective during the period of such interference, until the offering
of Registrable Securities pursuant to such Registration Statement may legally
resume.

         2.5 Additional Interest. The Indenture executed in connection with the
Securities will provide that in the event that either (a) the Exchange Offer
Registration Statement is not filed with the Commission on or prior to the 60th
calendar day following the date of original issue of the Securities, (b) the
Exchange Offer Registration Statement has not been declared effective on or
prior to the 150th calendar day following the date of original issue of the
Securities , (c) the Exchange Offer is not consummated on or prior to the 180th
calendar day following the date of original issue of the Securities or a Shelf
Registration Statement is not declared effective prior to the 150th day
following the date the obligation to file such Shelf Registration Statement
arises or (d) after the Shelf Registration Statement has been filed and declared
effective, the Shelf Registration Statement is


                                      -7-
   8

unusable by the Holders for any reason during the Effectiveness Period, and the
aggregate number of days in any consecutive twelve-month period for which the
Shelf Registration Statement shall not be usable exceeds 30 days in the
aggregate (each such event referred to in clauses (a) through (d) above, a
"Registration Default"), the interest rate borne by the Registrable Securities
shall be increased ("Additional Interest") by 0.25% per annum upon the
occurrence of each Registration Default, which rate will increase by 0.25% per
annum each 90-day period that such Additional Interest continues to accrue under
any such circumstance, provided that the maximum aggregate increase in the
interest rate will in no event exceed 0.50% per annum. Additional Interest shall
be computed based on the actual number of days elapsed in each period in which a
Registration Default occurs. Following the cure of all Registration Defaults the
accrual of Additional Interest will cease and the interest rate will revert to
the original rate.

         The Company 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"). Additional Interest shall be
paid by depositing with the Trustee, in trust, for the benefit of the Holders of
Registrable Securities, on or before the applicable semiannual interest payment
date, immediately available funds in sums sufficient to pay the Additional
Interest then due. The Additional Interest due shall be payable on each interest
payment date to the record Holder of Securities entitled to receive the interest
payment to be paid on such date as set forth in the Indenture. Each obligation
to pay Additional Interest shall be deemed to accrue from and including the day
following the applicable Event Date.

         Section 2 hereof;

                  (b) prepare and file with the SEC such amendments and

         underwritten offering of Registrable Securities shall reasonably
         request by the time the applicable Registration Statement is declared
         effective by the SEC, and do any and all other acts and things which
         may be reasonably necessary or advisable to enable each such Holder and
         underwriter to consummate the disposition in each such jurisdiction of
         such Registrable Securities owned by such Holder; provided, however,
         that the Company shall not be required to (i) qualify as a foreign
         corporation or as a dealer in securities in any jurisdiction where it
         would not otherwise be required to qualify but for this Section 3(d),
         or (ii) take any action which would subject it to general service of
         process or taxation in any such jurisdiction where it is not then so
         subject;

                  (e) notify promptly each Holder of Registrable Securities
         included in a Shelf Registration or any Participating Broker-Dealer who

         requested by such Holder or Participating Broker-Dealer, confirm such

         initiation of any proceedings for that purpose, (iv) of the happening
         of any event or the discovery of any facts during the period a Shelf
         Registration Statement is effective which makes any statement made in
         such Registration Statement or the related Prospectus untrue in any
         material respect or which requires the making of any changes in such
         Registration Statement or Prospectus in order to make the statements
         therein not misleading or to include omitted material information, (v)
         of the receipt by the Company of any notification with respect to the
         suspension of the qualification of the Registrable Securities or the
         Exchange Securities, as the case may be, for sale in any jurisdiction
         or the initiation or threatening of any proceeding for such purpose and

         account as a result of market-making activities or other trading
         activities and that will be the beneficial owner (as defined in Rule
         13d-3 under the Exchange Act) of Exchange Securities to be received by
         such broker-dealer in the Exchange Offer, 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, including a statement that any such broker-dealer who
         receives Exchange Securities for Registrable Securities pursuant to the
         Exchange Offer may be deemed a statutory underwriter and must deliver a
         prospectus meeting the requirements of the 1933 Act in connection with
         any resale of such Exchange Securities, (ii) furnish to each
         Participating Broker-Dealer who has delivered to the Company the notice

                  Registrable Securities acquired for its own account as a
                  result of market-making activities or other trading
                  activities, it will deliver a prospectus meeting the
                  requirements of the 1933 Act in connection with any resale of
                  Exchange Securities received in respect of such Registrable
                  Securities pursuant to the Exchange Offer;" and

         within the meaning of the 1933 Act; and

                  (B) in the case of any Exchange Offer Registration Statement,
         the Company agrees to deliver to the Initial Purchasers on behalf of
         the Participating Broker-Dealers upon the effectiveness of the Exchange
         Offer Registration Statement (i) an opinion of counsel or opinions of

         agreed upon procedures letter in customary form) from the Company's
         independent certified public accountants (and, if necessary, any other
         independent certified public accountants of any subsidiary of the
         Company or of any business acquired by the Company for which financial
         statements are, or are required to be, included in the Registration
         Statement) at least as broad in scope and coverage as the comfort
         letter or comfort letters delivered to the Initial Purchasers in
         connection with the initial sale of the Securities to the Initial
         Purchasers;

                  (g) (i) in the case of an Exchange Offer, furnish counsel for

                  (h) make every reasonable effort to obtain the withdrawal of
         any order suspending the effectiveness of a Registration Statement at
         the earliest possible moment;

                  (i) in the case of a Shelf Registration, furnish to each
         Holder of Registrable Securities, and each underwriter, if any, without

         enable such Registrable Securities to be in such denominations
         (consistent with the provisions of the Indenture) and registered in
         such names as


                                      -10-
   11

         the selling Holders or the underwriters, if any, may reasonably request
         at least three business days prior to the closing of any sale of
         Registrable Securities;

                  (k) in the case of a Shelf Registration, upon the occurrence
         of any event or the discovery of any facts, each as contemplated by
         Sections 3(e)(iv) and 3(e)(v) hereof, as promptly as practicable after
         the occurrence of such an event, subject to Section 2.2(b), use its
         reasonable best efforts to prepare a supplement or post-effective
         amendment to the Registration Statement or the related Prospectus or
         any document incorporated therein by reference or file any other
         required document so that, as thereafter delivered to the purchasers of
         the Registrable Securities or Participating Broker-Dealers, such
         Prospectus will not contain at the time of such delivery any untrue
         statement of a material fact or omit to state a material fact necessary
         to make the statements therein, in light of the circumstances under
         which they were made, not misleading or will remain so qualified. At
         such time as such public disclosure is otherwise made or the Company
         determines that such disclosure is not necessary, in each case to
         correct any misstatement of a material fact or to include any omitted
         material fact, the Company agrees promptly to notify each Holder of

         into a Registration Statement or a Prospectus after initial filing of a
         Registration Statement, provide copies of such document to the Initial
         Purchasers on behalf of such Holders; and make representatives of the
         Company as shall be reasonably requested by the holders of a majority
         of the Registrable Securities being sold, or the Initial Purchasers on
         behalf of such Holders, available for discussion of such document;

                  (m) obtain a CUSIP number for all Exchange Securities, Private
         Exchange Securities or Registrable Securities, as the case may be, not
         later than the effective date of a Registration Statement, and provide
         the Trustee with printed certificates for the Exchange Securities,
         Private Exchange Securities or the Registrable Securities, as the case
         may be, in a form eligible for deposit with the Depositary;

                  (n) (i) cause the Indenture to be qualified under the TIA in
         connection with the registration of the Exchange Securities or
         Registrable Securities, as the case may be, (ii) cooperate with the
         Trustee and the Holders to effect such changes to the Indenture as may

         to cause the Trustee to execute, all documents as may be required to
         effect such changes, and all other forms and documents required to be
         filed with the SEC to enable the Indenture to be so qualified in a
         timely manner;

                  (o) in the case of a Shelf Registration, enter into agreements
         (including underwriting agreements) and take all other customary and
         appropriate actions reasonably required in order to expedite or
         facilitate the disposition of such Registrable Securities:

                           (i) make such representations and warranties to the
                  Holders of such Registrable Securities and the underwriters,
                  if any, in form, substance and scope as are customarily made
                  by issuers to underwriters in similar underwritten offerings
                  as may be reasonably requested by them;

                  things, the appointment of such agent for the selling Holders
                  for the purpose of soliciting purchases of Registrable

         underwriter or underwriters reasonably request and not file any such
         document in a form to which the Majority Holders, the Initial
         Purchasers on behalf of the Holders of Registrable Securities, counsel
         for the Holders of Registrable Securities or any underwriter shall not
         have previously been advised and furnished a copy of or to which the
         Majority Holders, the Initial Purchasers of behalf of the Holders of
         Registrable Securities, counsel to the Holders of Registrable
         Securities or any underwriter shall reasonably object, and make the
         representatives of the Company available for discussion of such
         document as shall be reasonably requested by the Holders of Registrable
         Securities, the Initial Purchasers on behalf of such Holders, counsel
         for the Holders of Registrable Securities or any underwriter;

                  (r) otherwise comply with all applicable rules and regulations
         of the SEC and make available to its security holders, as soon as
         reasonably practicable, an earnings statement covering at least 12
         months which shall satisfy the provisions of Section 11(a) of the 1933
         Act and Rule 158 thereunder;

                  (s) cooperate and assist in any filings required to be made
         with the NASD and, in the case of a Shelf Registration, in the
         performance of any due diligence investigation by any underwriter and
         its counsel (including any "qualified independent underwriter" that is
         required to be retained in accordance with the rules and regulations of
         the NASD); and

                  (t) upon consummation of an Exchange Offer or a Private
         Exchange, obtain a customary opinion of counsel to the Company and the
         Guarantors addressed to the Trustee for the benefit of all Holders of
         Registrable Securities participating in the Exchange Offer or Private
         Exchange, and which includes an opinion that (i) the Company and the
         Guarantors have duly authorized, executed and delivered the Exchange
         Securities and/or Private Exchange Securities, as applicable, and the
         related indenture, and (ii) each of the Exchange Securities and related
         indenture constitute a legal, valid and binding obligation of the
         Company and the Guarantors, enforceable against the Company and the
         Guarantors in accordance with its respective terms (with customary
         exceptions).

         In the case of a Shelf Registration Statement, the Company may (as a
condition to such Holder's participation in the Shelf Registration) require each
Holder of Registrable Securities to furnish to the Company such information
regarding the Holder and the proposed distribution by such Holder of such
Registrable Securities as the Company may from time to time reasonably request
in writing.

         In the case of a Shelf Registration Statement, each Holder agrees that,
upon receipt of any notice from the Company of (a) the happening of any event or
the discovery of any facts, each of the kind described in Section 3(e)(iv)
hereof or (b) the Company's election to begin a Suspension Period pursuant to
Section 2.2(b), such Holder will forthwith discontinue disposition of
Registrable Securities pursuant to a Registration Statement until such Holder's
receipt of the copies of the supplemented or amended Prospectus contemplated by
Section 3(k) hereof or written notice from the Company of termination of such
Suspension Period, and, if so directed by the Company, such Holder will deliver
to the Company (at the Company's expense) all copies in such Holder's


                                      -13-
   14

possession, other than permanent file copies then in such Holder's possession,
of the Prospectus covering such Registrable Securities current at the time of
receipt of such notice.

         If any of the Registrable Securities covered by any Shelf Registration
Statement are to be sold in an underwritten offering, the underwriter or
underwriters and manager or managers that will manage such offering will be
selected by the Majority Holders of such Registrable Securities included in such
offering and shall be acceptable to the Company. No Holder of Registrable
Securities may participate in any underwritten registration hereunder unless
such Holder (a) agrees to sell such Holder's Registrable Securities 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.

         4. Indemnification; Contribution.

         (a) The Company and the Guarantors jointly and severally agree to
indemnify and hold harmless the Initial Purchasers, each Holder, each
Participating Broker-Dealer, each Person who participates as an underwriter (any
such Person being an "Underwriter") and each Person, if any, who controls any
Holder or Underwriter within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act as follows:

                  (i) against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, arising out of any untrue statement or
         alleged untrue statement of a material fact contained in any
         Registration Statement (or any amendment or supplement thereto)
         pursuant to which Exchange Securities or Registrable Securities were
         registered under the 1933 Act, including all documents incorporated
         therein by reference, or the omission or alleged omission therefrom of
         a material fact required to be stated therein or necessary to make the
         statements therein not misleading, or arising out of any untrue
         statement or alleged untrue statement of a material fact contained in
         any Prospectus (or any amendment or supplement thereto) or the omission
         or alleged omission therefrom of a material fact necessary in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading;

                 (ii) against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, to the extent of the aggregate amount
         paid in settlement of any litigation, or any investigation or
         proceeding by any governmental agency or body, commenced or threatened,
         or of any claim whatsoever based upon any such untrue statement or
         omission, or any such alleged untrue statement or omission; provided
         that (subject to Section 4(d) below) any such settlement is effected
         with the written consent of the Company; and

                (iii) against any and all expense whatsoever, as incurred
         (including the fees and disbursements of counsel chosen by any
         indemnified party), reasonably incurred in investigating, preparing or
         defending against any litigation, or any investigation or proceeding by
         any governmental agency or body, commenced or threatened, or any claim
         whatsoever based upon any such untrue statement or omission, or any
         such alleged untrue statement or omission, to the extent that any such
         expense is not paid under subparagraph (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by the
Holder or Underwriter expressly for use in a Registration Statement (or any
amendment thereto) or any Prospectus (or any amendment or supplement thereto).



                                      -14-
   15

         (b) Each Holder severally, but not jointly, agrees to indemnify and
hold harmless the Company, the Guarantors, the Initial Purchasers, each
Underwriter and the other selling Holders, and each of their respective
directors and officers, and each Person, if any, who controls the Company, any
Guarantor, any Initial Purchaser, any Underwriter or any other selling Holder
within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act,
against any and all loss, liability, claim, damage and expense described in the
indemnity contained in Section 4(a) hereof, as incurred, but only with respect
to untrue statements or omissions, or alleged untrue statements or omissions,
made in the Shelf Registration Statement (or any amendment thereto) or any
Prospectus included therein (or any amendment or supplement thereto) in reliance
upon and in conformity with written information with respect to such Holder
furnished to the Company by such Holder expressly for use in the Shelf
Registration Statement (or any amendment thereto) or such Prospectus (or any
amendment or supplement thereto); provided, however, that no such Holder shall
be liable for any claims hereunder in excess of the amount of net proceeds
received by such Holder from the sale of Registrable Securities pursuant to such
Registration Statement.

         (c) Each indemnified party shall give notice as promptly as reasonably
practicable to each indemnifying party of any action or proceeding commenced
against it in respect of which indemnity may be sought hereunder, but failure so
to notify an indemnifying party shall not relieve such indemnifying party from
any liability hereunder to the extent it is not materially prejudiced as a
result thereof and in any event shall not relieve it from any liability which it
may have otherwise than on account of this indemnity agreement. An indemnifying
party may participate at its own expense in the defense of such action;
provided, however, that counsel to the indemnifying party shall not (except with
the consent of the indemnified party) also be counsel to the indemnified party.
In no event shall the indemnifying party or parties be liable for the fees and
expenses of more than one counsel (in addition to any local counsel) separate
from their own counsel for all indemnified parties in connection with any one
action or separate but similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances. No indemnifying
party shall, without the prior written consent of the indemnified parties,
settle or compromise or consent to the entry of any judgment with respect to any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever in respect of which
indemnification or contribution could be sought under this Section 4 (whether or
not the indemnified parties are actual or potential parties thereto), unless
such settlement, compromise or consent (i) includes an unconditional release of
each indemnified party from all liability arising out of such litigation,
investigation, proceeding or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act by or on behalf of any
indemnified party.

         (d) If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 4(a)(ii) effected without its
written consent if (i) such settlement is entered into more than 45 days after
receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least 30 days prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement; provided,
however, that an indemnifying party shall not be liable for any such settlement
effected without its consent if such indemnifying party, prior to the date of
such settlement, (1) reimburses such indemnified party in accordance with such
request for the amount of such fees and expenses of counsel as the indemnifying
party believes in good faith to be reasonable, and (2) provides written notice
to the indemnified party that the indemnifying party disputes in good faith the
reasonableness of the unpaid balance of such fees and expenses.

         (e) If the indemnification provided for in this Section 4 is for any
reason unavailable to or insufficient to hold harmless an indemnified party in
respect of any losses, liabilities, claims, damages or expenses referred to
therein, then each indemnifying party shall contribute to the aggregate amount
of such losses, liabilities, claims, damages and expenses incurred by such
indemnified party, as incurred, in such proportion as is appropriate to reflect
the relative fault of the Company and the Guarantors on the one hand and the
Holders and the


                                      -15-
   16

Initial Purchasers on the other hand in connection with the statements or
omissions which resulted in such losses, liabilities, claims, damages or
expenses, as well as any other relevant equitable considerations.

         The relative fault of the Company and the Guarantors on the one hand
and the Holders and the Initial Purchasers on the other hand shall be determined
by reference to, among other things, whether any such untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact relates to information supplied by the Company, the Guarantors, the Holders
or the Initial Purchasers and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

         The Company, the Guarantors, the Holders and the Initial Purchasers
agree that it would not be just and equitable if contribution pursuant to this
Section 4 were determined by pro rata allocation (even if the Initial Purchasers
were treated as one entity for such purpose) or by any other method of
allocation which does not take account of the equitable considerations referred
to above in this Section 4. The aggregate amount of losses, liabilities, claims,
damages and expenses incurred by an indemnified party and referred to above in
this Section 4 shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in investigating, preparing or defending
against any litigation, or any investigation or proceeding by any governmental
agency or body, commenced or threatened, or any claim whatsoever based upon any
such untrue or alleged untrue statement or omission or alleged omission.

         Notwithstanding the provisions of this Section 4, no Initial Purchaser
shall be required to contribute any amount in excess of the amount by which the
total price at which the Securities sold by it were offered exceeds the amount
of any damages which such Initial Purchaser has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged
omission.

         No Person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

         For purposes of this Section 4, each Person, if any, who controls an
Initial Purchaser or Holder within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act shall have the same rights to contribution as such
Initial Purchaser or Holder, and each director of the Company or any Guarantor,
and each Person, if any, who controls the Company or any Guarantor within the
meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have
the same rights to contribution as the Company and the Guarantors. The Initial
Purchasers' respective obligations to contribute pursuant to this Section 4 are
several in proportion to the principal amount of Securities set forth opposite
their respective names in Schedule A to the Purchase Agreement and not joint.

         5. Miscellaneous.

         5.1 Rule 144 and Rule 144A. For so long as the Company is subject to
the reporting requirements of Section 13 or 15 of the 1934 Act, the Company
covenants that it will file the reports required to be filed by it under the
1933 Act and Section 13(a) or 15(d) of the 1934 Act and the rules and
regulations adopted by the SEC thereunder. If the Company ceases to be so
required to file such reports, the Company covenants that it will upon the
request of any Holder of Registrable Securities (a) make publicly available such
information as is necessary to permit sales pursuant to Rule 144 under the 1933
Act, (b) deliver such information to a prospective purchaser as is necessary to
permit sales pursuant to Rule 144A under the 1933 Act and it will take such
further action as any Holder of Registrable Securities may reasonably request,
and (c) take such further action that is reasonable in the circumstances, in
each case, to the extent required from time to time to enable such Holder to
sell its Registrable Securities without registration under the 1933 Act within
the limitation of the exemptions provided by (i) Rule 144 under the 1933 Act, as
such Rule may be amended from time to time, (ii) Rule 144A under the 1933 Act,
as such Rule may be amended from time to time, or (iii) any similar rules or
regulations


                                      -16-
   17

hereafter adopted by the SEC. Upon the request of any Holder of Registrable
Securities, the Company will deliver to such Holder a written statement as to
whether it has complied with such requirements.

         5.2 No Inconsistent Agreements. The Company has not entered into and
the Company will not after the date of this Agreement enter into any agreement
which is inconsistent with the rights granted to the Holders of Registrable
Securities in this Agreement or otherwise conflicts with the provisions hereof.
The rights granted to the Holders hereunder do not and will not for the term of
this Agreement in any way conflict with the rights granted to the holders of the
Company's other issued and outstanding securities under any such agreements.

         5.3 Amendments and Waivers. The provisions of this Agreement, including
the provisions of this sentence, may not be amended, modified or supplemented,
and waivers or consents to departures from the provisions hereof may not be
given unless the Company has obtained the written consent of the Majority
Holders affected by such amendment, modification, supplement, waiver or
departure.

         5.4 Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand delivery, registered
first-class mail, telex, telecopier, or any courier guaranteeing overnight
delivery (a) if to a Holder, at the most current address given by such Holder to
the Company by means of a notice given in accordance with the provisions of this
Section 5.4, which address initially is the address set forth in the Purchase
Agreement with respect to the Initial Purchasers; and (b) if to the Company or
any Guarantor, initially at the Company's address set forth in the Purchase
Agreement, and thereafter at such other address of which notice is given in
accordance with the provisions of this Section 5.4.

         All such notices and communications shall be deemed to have been duly
given: at the time delivered by hand, if personally delivered; two business days
after being deposited in the mail, postage prepaid, if mailed; when answered
back, if telexed; when receipt is acknowledged, if telecopied; and on the next
business day if timely delivered to an air courier guaranteeing overnight
delivery.

         Copies of all such notices, demands, or other communications shall be
concurrently delivered by the person giving the same to the Trustee under the
Indenture, at the address specified in such Indenture.

         5.5 Successor and Assigns. This Agreement shall inure to the benefit of
and be binding upon the successors, assigns and transferees of each of the
parties, including, without limitation and without the need for an express
assignment, subsequent Holders; provided that nothing herein shall be deemed to
permit any assignment, transfer or other disposition of Registrable Securities
in violation of the terms of the Purchase Agreement or the Indenture. If any
transferee of any Holder shall acquire Registrable Securities, in any manner,
whether by operation of law or otherwise, such Registrable Securities shall be
held subject to all of the terms of this Agreement, and by taking and holding
such Registrable Securities such person shall be conclusively deemed to have
agreed to be bound by and to perform all of the terms and provisions of this
Agreement, including the restrictions on resale set forth in this Agreement and,
if applicable, the Purchase Agreement, and such person shall be entitled to
receive the benefits hereof.

         5.6 Third Party Beneficiaries. The Initial Purchasers (even if the
Initial Purchasers are not Holders of Registrable Securities) shall be third
party beneficiaries to the agreements made hereunder between the Company and the
Guarantors, on the one hand, and the Holders, on the other hand, and shall have
the right to enforce such agreements directly to the extent they deem such
enforcement necessary or advisable to protect their rights or the rights of
Holders hereunder. Each Holder of Registrable Securities shall be a third party
beneficiary to the agreements made hereunder between the Company and the
Guarantors, on the one hand, and the Initial Purchasers, on the other hand, and
shall have the right to enforce such agreements directly to the extent it deems
such enforcement necessary or advisable to protect its rights hereunder.



                                      -17-
   18

         5.7 Specific Enforcement. Without limiting the remedies available to
the Initial Purchasers and the Holders, the Company and the Guarantors
acknowledge that any failure by the Company and the Guarantors to comply with
their obligations under Sections 2.1 through 2.4 hereof may result in material
irreparable injury to the Initial Purchasers or the Holders for which there is
no adequate remedy at law, that it would not be possible to measure damages for
such injuries precisely and that, in the event of any such failure, the Initial
Purchasers or any Holder may obtain such relief as may be required to
specifically enforce the obligations of the Company and the Guarantors under
Sections 2.1 through 2.4 hereof.

         5.8 Restriction on Resales. Until the expiration of two years after the
original issuance of the Securities, the Company and the Guarantors will not
resell any Securities which are "restricted securities" (as such term is defined
under Rule 144(a)(3) under the 1933 Act) that have been reacquired by any of
them and shall immediately upon any purchase of any such Securities submit such
Securities to the Trustee for cancellation.

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

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

         5.11 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE
PRINCIPLES OF CONFLICT OF LAWS THEREOF. SPECIFIED TIMES OF DAY REFER TO NEW YORK
CITY TIME.

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

Ladies and Gentlemen:

         We have acted as counsel for American Plumbing & Mechanical, Inc., a
Delaware corporation (the "Company") and the Guarantors described below in
connection with the sale by the Company to the Initial Purchasers (as defined
below) of $150,000,000 aggregate principal amount of 11 5/8% Senior Subordinated
Notes due 2009 (the "Notes") of the Company together with the related guarantees
of the obligation of the Company under such Notes, pursuant to the Purchase
Agreement dated May 12, 1999 (the "Purchase Agreement") among the Company, the
Guarantors named therein (the "Guarantors") and Fleet Securities, Inc., Merrill
Lynch, Pierce, Fenner & Smith Incorporated, Banc One Capital Markets, Inc. and
Credit Lyonnais Securities (USA) Inc. (collectively, the "Initial Purchasers")
and the filing by the Company and the Guarantors of an Exchange Offer
Registration Statement (the "Registration Statement") in connection with an
Exchange Offer to be effected pursuant to the Registration Rights Agreement (the
"Registration Rights Agreement"), dated May 19, 1999 among the Company, the
Guarantors and the Initial Purchasers. This opinion is furnished to you pursuant
to Section 3(f)(B) of the Registration Rights Agreement. Unless otherwise
defined herein, capitalized terms used in this opinion that are defined in the
Registration Rights Agreement are used herein as so defined.

         We have examined such documents, records and matters of law as we have
deemed necessary for purposes of this opinion. In rendering this opinion, as to
all matters of fact relevant to this opinion, we have assumed the completeness
and accuracy of, and are relying solely upon, the representations and warranties
of the Company and the Guarantors set forth in the Purchase Agreement and the
statements set forth in certificates of public officials and officers of the
Company and the Guarantors, without making any independent investigation or
inquiry with respect to the completeness or accuracy of such representations,
warranties or statements, other than a review of the certificate of
incorporation, by-laws and relevant minute books of the Company and the
Guarantors.

         Based on and subject to the foregoing, we are of the opinion that:

         1. The Exchange Offer Registration Statement and the Prospectus (other
than the financial statements, notes or schedules thereto and other financial
data and supplemental schedules included or incorporated by reference therein or
omitted therefrom and the Form T-1, as to which such counsel need express no
opinion), comply as to form in all material respects with the requirements of
the 1933 Act and the applicable rules and regulations promulgated under the 1933
Act.

         2. We have participated in the preparation of the Registration
Statement and the Prospectus and in the course thereof have had discussions with
representatives of the Underwriters, officers and other representatives of the
Company and the Company's independent public accountants, during which the
contents of the Registration Statement and the Prospectus were discussed. We
have not, however, independently verified and are not passing upon, and do not
assume any responsibility for, the accuracy, completeness or fairness of the
statements contained in the Registration Statement and the Prospectus. Based on
our participation as described above, nothing has come to our attention that
would lead us to believe that the Registration Statement (except for financial
statements and schedules and other financial data included therein as to which
we make no statement) contained an untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein not misleading or that the Prospectus or any
amendment or supplement thereto (except for financial statements and schedules
and other financial data included therein, as to which such counsel need make no
statement), at the time the Prospectus was issued, at the time any such amended
or supplemented Prospectus was issued or at the Closing Time, included or
includes an untrue statement of a material fact or omitted or omits 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.

         This opinion is being furnished to you solely for your benefit in
connection with the transactions contemplated by the Registration Rights
Agreement, and may not be used for any other purpose or relied upon by any
person other than you. Except with our prior written consent, the opinions
herein expressed are not to be used, circulated, quoted or otherwise referred to
in connection with any transactions other than those contemplated by the
Registration Rights Agreement by or to any other person.

                                                     Very truly yours,


                                      -2-
