            TRANSFER RESTRICTION AND EXPENSE REIMBURSEMENT AGREEMENT


         For good and valuable consideration, the receipt and sufficiency of
which is hereby acknowledged, American Plumbing & Mechanical, Inc., a Delaware
corporation (the "Company") and the undersigned, being stockholders of the
Company (the "Undersigned") hereby agree as follows:

1.       TRANSFER RESTRICTIONS

         1.1 TRANSFER RESTRICTIONS. For a period of two years from the date of
issuance or, in the event that the Company completes a firm commitment
underwritten initial public offering of shares of stock of the Company managed
by one or more nationally recognized national investment banking firms (an
"IPO"), for a period through the second anniversary of the date of the closing
of such IPO (the "Restricted Period"), the Undersigned shall not (i) sell,
assign, exchange, transfer, pledge, or otherwise dispose of any shares of
restricted common stock or common stock of the Company (the "Stock") currently
owned or held by the Undersigned or any securities convertible into,
exchangeable or exercisable for any shares of Stock, (ii) grant any option to
purchase, or otherwise enter into any contract to sell, assign, transfer,
pledge or otherwise dispose of, any shares of Stock currently owned or held by
the Undersigned, or (iii) enter into any swap or any other agreement or any
transaction that transfers, in whole or in part, directly or indirectly, the
economic consequence of ownership of any currently owned or held Stock, whether
any such swap or transaction is to be settled by delivery of shares of Stock or
other securities, by the delivery or payment of cash or otherwise, except, in
the case of clauses (i), (ii) or (iii) above, (A) as otherwise agreed by the
Company, (B) for the sale of shares of Stock, and entering into agreements
relating to the sale of shares of Stock, pursuant to Section 3 hereof, (C) for
transfers to (I) immediate family members of the Undersigned or to equity
owners or members of the Undersigned who agree with the Company in writing to
be bound by the restrictions set forth in this Section 1.1, (II) trusts,
limited partnerships or other estate planning entities for the benefit of the
Undersigned or family members of the Undersigned which have agreed with the
Company in writing, through action taken by the trustees, partners or other
persons having authority to bind the trust, limited partnership or other estate
planning entity, to be bound by the restrictions set forth in this Section 1.1,
(III) any charitable organization that qualifies for receipt of charitable
contributions under Section 170(c) of the Code which agrees with the Company in
writing to be bound by the restrictions set forth in this Section 1.1, (D) the
sale by the Undersigned in an IPO of shares of Stock, provided that if the
Company is advised in writing in good faith by any managing underwriter of an
underwritten offering of the securities being offered pursuant to any
registration statement under Section 3.1 that the number of shares to be sold
by persons other than the Company is greater than the number of such shares
which can be offered without adversely affecting the success of the offering,
the Company may reduce pro rata (among the Undersigned and all other selling
security holders in the offering) the number of shares offered for the accounts
of such persons (based upon the number of shares held by such person) to a
number deemed satisfactory by such managing underwriter. During the Restricted
Period, the certificates evidencing the Stock owned or held by the Undersigned
will bear a legend substantially in the form set forth below:


                                      -1-

   2


THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED,
EXCHANGED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF WITHOUT THE WRITTEN
CONSENT OF THE COMPANY, AND THE COMPANY SHALL NOT BE REQUIRED TO GIVE EFFECT TO
ANY ATTEMPTED SALE, ASSIGNMENT, EXCHANGE, TRANSFER, PLEDGE OR OTHER DISPOSITION
PRIOR TO EXPIRATION OF TWO YEARS. SUCH RESTRICTIONS ON TRANSFER ARE SET FORTH
IN A TRANSFER RESTRICTION AGREEMENT, A COPY OF WHICH IS MAINTAINED AT THE
PRINCIPAL OFFICES OF THE COMPANY. UPON THE WRITTEN REQUEST OF THE HOLDER OF
THIS CERTIFICATE, THE COMPANY AGREES TO REMOVE THIS RESTRICTIVE LEGEND (AND ANY
STOP ORDER PLACED WITH THE TRANSFER AGENT) AFTER THE DATE SPECIFIED ABOVE.

2.       FEDERAL SECURITIES ACT REPRESENTATIONS

         2.1 COMPLIANCE WITH LAW. The Undersigned acknowledges that the shares
of Stock have not been and will not be registered under the Securities Act of
1933, as amended (the "1933 Act") (except as provided in Section 3 hereof) and
therefore may not be sold, assigned, exchanged, transferred, pledged or
otherwise disposed of without compliance with the 1933 Act which, among other
matters, would require registration under the 1933 Act unless exemption from
the registration requirements is available for such transaction. The Stock was
being acquired solely for the Undersigned's own account, for investment
purposes only, and with no present intention of selling, assigning, exchanging,
transferring, pledging, or otherwise disposing of it. The Undersigned
covenants, warrants and represents that neither the shares of Stock issued to
the Undersigned was offered, sold, assigned, exchanged, pledged, transferred or
otherwise disposed of except after full compliance with all of the applicable
provisions of the 1933 Act and the rules and regulations of the SEC. All
certificates representing the Stock shall bear the following legend in addition
to the legend required under Section 1 of this Agreement:

THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IF THE HOLDER
HEREOF COMPLIES WITH THE ACT AND APPLICABLE FEDERAL AND STATE SECURITIES LAWS.

3.       REGISTRATION RIGHTS

         3.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the date
hereof, whenever the Company proposes to register any Stock for its own or
other's account under the 1933 Act for a public offering, other than (i) any
shelf or other registration of shares to be used as consideration for
acquisitions of additional businesses by the Company and (ii) registrations
relating to employee benefit plans, the Company shall give the Undersigned
prompt written notice of its intent to do so. Upon the written request of the
Undersigned given within 15 calendar days after receipt of such notice,
notwithstanding the provisions of Section 1 (except as specified below with
respect to an IPO), the Company shall cause to be included in such registration
all of the Stock held or owned by


                                      -2-

   3


the Undersigned (including any stock issued as or issuable upon the conversion
or exchange of any convertible security, warrant, right or other security which
is issued by the Company as a stock split, dividend or other distribution with
respect to, or in exchange for, or in replacement of such Stock) which the
Undersigned requests, other than shares of Stock which may then be immediately
sold under Rule 144(k) (or any similar or successor provision) promulgated
under the 1933 Act, and other than shares of Stock that have been theretofore
sold by the Undersigned in accordance with the 1933 Act. In addition, if the
Company is advised in writing in good faith by any managing underwriter of an
underwritten offering of the securities being offered pursuant to any
registration statement under this Section 3.1 that the number of shares to be
sold by persons other than the Company is greater than the number of such
shares which can be offered without adversely affecting the success of the
offering, the Company may reduce pro rata (among the Undersigned and all other
selling security holders in the offering) the number of shares offered for the
accounts of such persons (based upon the number of shares held by such person)
to a number deemed satisfactory by such managing underwriter. If the
Undersigned disapproves of the terms of the underwriting, the Undersigned may
elect to withdraw therefrom by written notice to the Company and the managing
underwriter. The Undersigned's shares of Stock so withdrawn shall also be
withdrawn from registration.

         3.2 REGISTRATION PROCEDURES. Whenever the Company is required to
register shares of Stock pursuant to Section 3.1, the Company will, as
expeditiously as possible:

             (i) Prepare and file with the Securities and Exchange Commission
         (the "SEC") a registration statement with respect to such shares and
         use its best efforts to cause such registration statement to become
         effective (provided that before filing a registration statement or
         prospectus or any amendments or supplements or term sheets thereto,
         the Company will furnish a representative of the Undersigned with
         copies of all such documents proposed to be filed) as promptly as
         practical;

             (ii) Notify the Undersigned of any stop order issued or threatened
         by the SEC and take all reasonable actions required to prevent the
         entry of such stop order or to remove it if entered;

             (iii) Prepare and file with the SEC such amendments and
         supplements to such registration statement and the prospectus used in
         connection therewith as may be necessary to keep such registration
         statement effective for a period of not less than 120 days, cause the
         prospectus to be supplemented by any required prospectus supplement,
         and as so supplemented to be filed pursuant to Rule 424 under the 1933
         Act; and comply with the provisions of the 1933 Act applicable to it
         with respect to the disposition of all securities covered by such
         registration statement during the applicable period in accordance with
         the intended methods of disposition by the sellers thereof set forth
         in such registration statement or supplement to the prospectus;

             (iv) Furnish to the Undersigned upon request such number of copies
         of such registration statement, each amendment and supplement thereto
         and the prospectus included

                                      -3-

   4



         in such registration statement (including each preliminary prospectus
         and any term sheet associated therewith), and such other documents as
         the Undersigned may reasonably request in order to facilitate the
         disposition of the relevant shares;

             (v) Make "generally available to its security holders" (within the
         meaning of Rule 158) an earnings statement satisfying the provisions
         of Section 11(a) of the 1933 Act and Rule 158 thereunder no later than
         90 days after the end of the 12-month period beginning with the first
         day of the Company's first fiscal quarter commencing after the
         effective date of the registration statement;

             (vi) Make every reasonable effort to obtain the withdrawal of any
         order suspending the effectiveness of the registration statement at
         the earliest possible moment;

             (vii) If requested by the managing underwriter or underwriters, if
         any, or any participating stockholder, promptly incorporate in a
         prospectus supplement or post-effective amendment such information as
         the managing underwriter or underwriters or any participating
         stockholder, as the case may be, reasonably requests to be included
         therein, including, without limitation, information with respect to
         the number of shares of Stock being sold by participating stockholders
         to any underwriter or underwriters, the purchase price being paid
         therefor by such underwriter or underwriters and with respect to any
         other terms of an underwritten offering of the shares of Stock to be
         sold in such offering, and promptly make all required filings of such
         prospectus by supplement or post-effective amendment;

             (viii) Make available for inspection by participating
         stockholders, any underwriter participating in any disposition
         pursuant to such registration statement, and the counsel retained by
         the participating stockholders, counsel for the underwriters and any
         accountant or other agent retained by participating stockholders or
         any such underwriter (collectively, the "Inspectors"), all financial
         and other records, pertinent corporate documents and properties of the
         Company (the "Records"), as shall be reasonably necessary to enable
         them to exercise their due diligence responsibility, and cause the
         Company's officers, directors and employees to supply all information
         reasonably requested by any such Inspectors in connection with such
         registration statement; provided, that records which the Company
         determines, in good faith, to be confidential and which the Company
         notifies the Inspectors are confidential shall not be disclosed by the
         Inspectors unless (i) the disclosure of such Records is necessary to
         avoid or correct a misstatement or omission in the registration
         statement or (ii) the release of such Records is ordered pursuant to a
         subpoena or other order from a court of competent jurisdiction after
         delivery of sufficient notice to the Company to enable the Company to
         contest such subpoena or order;

             (ix) Take all other steps reasonably necessary to effect the
         registration of the shares of Stock contemplated hereby;


                                      -4-

   5


             (x) Use its best efforts to register or qualify the securities
         covered by such registration statement under such other securities or
         blue sky laws of such jurisdictions as shall be reasonably requested
         by the Undersigned, and to keep such registration or qualification
         effective during the period such registration statement is required to
         be kept effective, provided that the Company shall not be required to
         become subject to taxation, to qualify generally to do business or to
         file a general consent to service of process in any such states or
         jurisdictions;

             (xi) Cause all such shares of Stock to be listed or included not
         later than the date of the first sale of shares of Stock under such
         registration statement on any securities exchanges or trading systems
         on which similar securities issued by the Company are then listed or
         included; and

             (xii) Notify the Undersigned at any time when a prospectus
         relating thereto is required to be delivered under the 1933 Act within
         the period that the Company is required to keep the registration
         statement effective of the happening of any event as a result of which
         the prospectus included in such registration statement (as then in
         effect), together with any associated term sheet, contains an untrue
         statement of a material fact or omits to state any fact required to be
         stated therein or necessary to make the statements therein (in the
         case of the prospectus or any preliminary prospectus, in light of the
         circumstances under which they were made) not misleading, and, at the
         request of the Undersigned, the Company promptly will prepare a
         supplement or amendment to such prospectus so that, as thereafter
         delivered to the purchasers of the covered shares, such prospectus
         will not contain an untrue statement of material fact or omit to state
         any fact required to be stated therein or necessary to make the
         statements therein (in the case of the prospectus or any preliminary
         prospectus, in light of the circumstances under which they were made)
         not misleading.

         All expenses incurred in connection with the registration under this
Article 3 and compliance with securities and blue sky laws (including all
registration, filing, listing, escrow agent, qualification, legal, printer and
accounting fees, but excluding underwriting commissions and discounts), shall
be borne by the Company.

         3.3      INDEMNIFICATION.

                  (a) In connection with any registration under Section 3.1,
the Company shall indemnify, to the extent permitted by law, the Undersigned
(an "Indemnified Party") against all losses, claims, damages, liabilities and
expenses arising out of or resulting from any untrue or alleged untrue
statement of material fact contained or incorporated by reference in any
registration statement, prospectus or preliminary prospectus or associated term
sheet or any omission or alleged omission to state or incorporated by reference
therein a material fact required to be stated or incorporated by reference
therein or necessary to make the statements therein not misleading except
insofar as the same are caused by or contained in or omitted from any
information furnished in writing to the Company by such Indemnified Party
expressly for use therein or by any Indemnified Parties' failure

                                      -5-

   6


to deliver a copy of the registration statement or prospectus or any amendment
or supplements thereto after the Company has furnished such Indemnified Party
with a sufficient number of copies of the same.

                  (b) In connection with any registration under Section 3.1,
the Undersigned shall furnish to the Company in writing such information
concerning the Undersigned and his or her proposed offering of shares as is
reasonably requested by the Company for use in any such registration statement
or prospectus and will indemnify, to the extent permitted by law, the Company,
its directors and officers and each person who controls the Company (within the
meaning of the 1933 Act) against any losses, claims, damages, liabilities and
expenses resulting from any untrue or alleged untrue statement of a material
fact or any omission or alleged omission to state therein a material fact
required to be stated in the registration statement or prospectus or any
amendment thereof or supplement thereto or necessary to make the statements
therein not misleading, but only to the extent that such untrue or alleged
untrue statement or omission or alleged omission is contained in or omitted
from information so furnished in writing to the Company by the Undersigned
expressly for use in the registration statement. Notwithstanding the foregoing,
the liability of the Undersigned under this Section 3.3 shall be limited to an
amount equal to the net proceeds actually received by the Undersigned from the
sale of the relevant shares covered by the registration statement.

                  (c) Any person entitled to indemnification hereunder will (i)
give prompt notice to the indemnifying party of any claim with respect to which
it seeks indemnification and (ii) unless in such indemnified parties'
reasonable judgment, a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. Any failure to give prompt notice shall
deprive a party of its right to indemnification hereunder only to the extent
that such failure shall have adversely affected the indemnifying party. If the
defense of any claim is assumed, the indemnifying party will not be subject to
any liability for any settlement made without its consent (but such consent
shall not be unreasonably withheld). An indemnifying party that is not entitled
or elects not, to assume the defense of a claim, will not be obligated to pay
the fees and expenses of more than one counsel for all parties indemnified by
such indemnifying party with respect to such claim, unless in the reasonable
judgment of any indemnified party, a conflict of interest may exist between
such indemnified party and any other of such indemnified parties with respect
to such claim.

         3.4 UNDERWRITING AGREEMENT. In connection with each registration
pursuant to Section 3.1 covering an underwritten registered offering, (i) the
Undersigned shall execute and deliver to the Company a written power of
attorney instrument that (A) appoints an officer of the Company as the
Undersigned's attorney-in-fact for purposes of executing and delivering an
underwriting agreement among the Company, the underwriters named therein and
the Undersigned specifying the terms and conditions applicable to the sale of
Stock of the Undersigned in such offering and (B) otherwise is in such form and
containing such provisions as are customary in the securities business for such
an arrangement in connection with an underwritten registered offering

                                      -6-

   7


in which one or more stockholders of the issuer are participants, including a
provision that authorizes the attorney-in-fact appointed by the Undersigned to
execute and deliver such an underwriting agreement in the event that the net
price per share to be received by the Undersigned from the sale of the shares
of Stock to be sold in such offering is not less than a price specified in such
instrument and (iii) the Company and the Undersigned agree to enter into a
written agreement with the managing underwriters in such form and containing
such provisions as are customary in the securities business for such an
arrangement between such managing underwriters and companies of the Company's
size and investment stature, including indemnification; provided, however, that
(A) the Undersigned shall be exempt and excluded from any indemnification of
the managing underwriters other than with respect to information provided by
the Undersigned with respect to the Undersigned to the Company or the managing
underwriters specifically for inclusion in any such registration statement and
(B) the Undersigned shall not be obligated to enter into such an underwriting
agreement in the event that the net price per share to be received by the
Undersigned from the sale of shares of Stock to be sold in such offering is
less than the floor price specified in the power of attorney instrument
executed and delivered to the Company pursuant to clause (i) above.

         3.5 TRANSFER OF RIGHTS. The right to cause the Company to register
shares of Stock under this Agreement may be assigned to a transferee or
assignee of the Undersigned to the extent that such transferee or assignee is a
member of the immediate family of the Undersigned, a trust, limited partnership
or other estate planning entity for the benefit of any such persons or a
charitable organization that qualifies for receipt of charitable contributions
under Section 170(c) of the Code.

         3.6 RULE 144 REPORTING. With a view to making available the benefits
of certain rules and regulations of the SEC that may permit the sale of stock
to the public without registration, following an IPO the Company agrees to use
its reasonable efforts, from and after the completion of an IPO, to:

             (i) make and keep public information regarding the Company
         available as those terms are understood and defined in Rule 144 under
         the 1933 Act beginning 90 days following the effective date of a
         registration statement relating to an IPO;

             (ii) file with the SEC in a timely manner all reports and other
         documents required of the Company under the 1933 Act and the 1934 Act
         at any time after it has become subject to such reporting
         requirements; and

             (iii) so long as the Undersigned owns any restricted Stock,
         furnish to the Undersigned forthwith upon written request a written
         statement by the Company as to its compliance with the current public
         information requirements of Rule 144 (at any time from and after 90
         days following the effective date of a registration statement relating
         to an IPO), and of the 1933 Act and the 1934 Act (any time after it
         has become subject to such reporting requirements), a copy of the most
         recent annual or quarterly report of the Company, and such other
         reports and documents so filed as the Undersigned may reasonably
         request in availing itself of any rule or regulation of the SEC
         allowing the Undersigned to sell any such shares without registration.
