                            INDEMNIFICATION AGREEMENT

         This Agreement ("Agreement") is made and entered into effective as of
the day of , 1999, by and between American Plumbing & Mechanical, Inc., a
Delaware corporation (the "Corporation"), and ________________________
("Indemnitee").

                                    RECITALS

         A. Highly competent persons are becoming more reluctant to serve
corporations as directors, executive officers or in other capacities unless they
are provided with adequate protection through insurance or adequate
indemnification against inordinate risks of claims and actions against them
arising out of their service to and activities on behalf of the corporation.

         B. The Board of Directors of the Corporation (the "Board") has
determined that the inability to attract and retain such persons would be
detrimental to the best interests of the Corporation and its shareholders and
that the Corporation should act to assure such persons that there will be
increased certainty of such protection in the future.

         C. The Board has also determined that it is reasonable, prudent and
necessary for the Corporation, in addition to purchasing and maintaining
directors' and officers' liability insurance, contractually to obligate itself
to indemnify such persons to the fullest extent permitted by applicable law and
to provide an arrangement of self-insurance so that they will serve or continue
to serve the Corporation free from undue concern that they will not be so
indemnified.

         D. Indemnitee is willing to serve or continue to serve on the condition
that he be so indemnified.

         In consideration of the mutual covenants herein contained, the parties
agree as follows:

                                    ARTICLE I

                                   ARTICLE II

                             SERVICES BY INDEMNITEE

         Indemnitee agrees to serve or continue to serve as a director or
officer of the Corporation. Indemnitee may from time to time also agree to
serve, as the Corporation may request from time to time, as a director, officer,
partner, employee, agent or fiduciary of either the Corporation or any other
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise in which the Corporation has an interest. Indemnitee and the
Corporation each acknowledge that they have entered into this Agreement as a
means of inducing Indemnitee to serve or continue to serve the Corporation in
such capacities. Indemnitee may at any time and for any reason resign from such
position or positions (subject to any other contractual obligation or any
obligation imposed by operation of law). The Corporation shall have no
obligation under this Agreement to continue Indemnitee in any such position or
positions.

                                   ARTICLE III

                                 INDEMNIFICATION

         Section 3.1 General. The Corporation shall indemnify, and advance
Expenses, to Indemnitee to the fullest extent permitted by applicable law in
effect on the date hereof and (without the necessity of any action to the
Corporation or Indemnitee) to such greater extent as applicable law may
hereafter from time to time permit. The rights of Indemnitee provided under the
preceding sentence shall include, but shall not be limited to, the right to be
indemnified and to have Expenses advanced in all Proceedings to the fullest
extent permitted by Section 145 of the DGCL as it currently exists or as it may
more fully permit in the future. The provisions set forth in this Agreement are
provided in addition to and as a means of furtherance and implementation of, and
not in limitation of, the obligations expressed in this Article III. No
requirement, condition to or limitation of any right to indemnification under
this Article III, or to advancement of Expenses under Articles III and IV shall
in any way limit the rights of Indemnitee under Section 7.2.

         Section 3.2 Additional Indemnity of the Corporation. Indemnitee shall
be entitled to indemnification pursuant to this Section 3.2 if, by reason of his
Corporate Status, he is, or is threatened to be made, a party to any Proceeding
(except to the extent limited by Section 3.3). Pursuant to this Section 3.2,
Indemnitee shall be indemnified against Expenses, judgments, penalties
(including excise or similar taxes), fines and amounts paid in settlement
actually and reasonably incurred by him or on his behalf in connection with such
Proceeding or any Claim therein, including but not limited to special, indirect,
incidental, consequential, treble, additional, punitive or exemplary damages if
(1) he conducted himself in good faith; (2) he reasonably believed: (a) in the
case of conduct in his official capacity, that his conduct was in the
Corporation's best interest; and (b) in all other cases, that his conduct was at
least not opposed to the Corporation's best interests and, (3) in the case of
any criminal Proceeding, had no reasonable cause to believe his conduct was
unlawful. Nothing in this Section 3.2 shall limit the benefits of Section 3.1 or
any other Section hereunder.


                                       -3-

   4


         Section 3.3 Limitation on Indemnity. The Indemnification otherwise
available to an Indemnitee under Section 3.2 shall be limited to the extent set
forth in this Section 3.3. In the event that an Indemnitee is found liable to
the Corporation or is found liable on the basis that personal benefit was
improperly received by the Indemnitee whether or not the benefit resulted from
an action taken in Indemnitee's official capacity the Indemnitee shall, with
respect to the Claim in the Proceeding in which such finding is made, be
indemnified only against reasonable expenses actually incurred by him in
connection with that Claim. Notwithstanding the foregoing, no indemnification
against such Expenses shall be made in respect of any Claim in such Proceeding
as to which Indemnitee shall have been adjudged to be liable for willful or
intentional misconduct in the performance of his duty to the Corporation
provided, however, that, if applicable law so permits, indemnification against
such Expenses shall nevertheless be made by the Corporation in such event if and
only to the extent that the court in which such Proceeding shall have been
brought or is pending, shall determine. In addition, no indemnification against
such Expenses shall be made on account of any suit in which final judgment is
rendered against Indemnitee for an accounting of profits made from sale or
purchase by Indemnitee of securities of the Corporation pursuant to the
provisions of Section 16(b) of the Exchange Act. In respect of remuneration paid
to Indemnitee, no indemnity shall be paid by the Corporation if it shall be
determined by a final judgment or other final adjudication that payment of such
remuneration was in violation of applicable law.

         Section 3.4 Notification and Defense of Claims. (a) Promptly after the
receipt by Indemnitee of notice of the commencement of any Proceeding,
Indemnitee will, if indemnification in respect thereof is to be requested the
Corporation under this Agreement, notify the Corporation of the commencement of
such Proceeding; provided, however, that the omission to so notify the
Corporation will not relieve the Corporation (i) from any liability which it may
have to Indemnitee under this Agreement unless, and then only to the extent
that, such omission results in insufficient time being available to permit the
Corporation or its counsel to effectively defend against or make timely response
to any Claim Expense, loss, damage, or liability resulting from such Proceeding
or otherwise has a material adverse effect on the Corporation's ability to
promptly deal with such Claim Expense, loss, claim, damage liability or (ii)
from any liability which it may have to Indemnitee otherwise than under this
Agreement.

                  (b) The following provisions shall apply with respect to any
such Proceeding as to which Indemnitee notifies the Corporation of the
commencement thereof:

                  (i) The Corporation shall be entitled to participate therein
         at its own expense.

                  (ii) Except as otherwise provided below, to the extent it may
         elect to do so, the Corporation (jointly with any other indemnifying
         party similarly notified) will be entitled to assume the defense
         thereof, with counsel of its own selection reasonably satisfactory to
         Indemnitee. After notice from the Corporation to Indemnitee of its
         election to so assume the defense thereof, the Corporation will not be
         liable to Indemnitee under this Agreement for any Expenses subsequently
         incurred by Indemnitee in connection with the defense of such
         Proceeding other than reasonable costs of investigation or as otherwise
         provided below.


                                       -4-

   5


         Indemnitee shall have the right to employ separate counsel in such
         Proceeding but the fees and expenses of such counsel incurred after
         notice from the Corporation of its assumption of the defense thereof
         shall be at the expense of Indemnitee unless (1) the employment of
         separate counsel by Indemnitee has been authorized by the Corporation;
         (2) Indemnitee shall have reasonably concluded that there may be a
         conflict of interest between the Corporation and Indemnitee in the
         conduct of the defense of such Proceeding; or (3) the Corporation shall
         not in fact have employed counsel to assume the defense of such
         Proceeding, in each of which cases the reasonable fees and expenses of
         Indemnitee's counsel shall be borne by the Corporation. The Corporation
         shall not be entitled to assume the defense of any Proceeding brought
         by or on behalf of the Corporation or as to which Indemnitee shall have
         made the conclusion provided for in (2) above. Nothing in this
         paragraph (ii) shall affect the obligation of the Corporation to
         indemnify Indemnitee against Expenses and liabilities paid in
         settlement for which it is otherwise obligated hereunder.

                  (iii) The Corporation shall not be liable to indemnify
         Indemnitee under this Agreement for any amounts paid in settlement of
         any Proceedings or Claims effected without its prior written consent.
         The Corporation shall not settle any Proceeding or claim in any manner
         which would impose any penalty or limitation on Indemnitee without
         Indemnitee's prior written consent. Neither the Corporation nor
         Indemnitee will unreasonably withhold or delay its consent to any
         proposed settlement.

                  (c) The Corporation agrees to promptly notify Indemnitee in
writing, as to the pendency of any Proceeding or Claim which may involve a claim
against the Indemnitee for which Indemnitee may be entitled to indemnification
or advancement of Expenses hereunder.

                                   ARTICLE IV

                                    EXPENSES

         Section 4.1 Expenses of a Party Who Is Wholly or Partly Successful.
Notwithstanding any other provision of this Agreement, Indemnitee shall be
indemnified against all Expenses actually and reasonably incurred by him in
connection with any Proceeding to which Indemnitee is a party by reason of his
Corporate Status and in which Indemnitee is successful, on the merits or
otherwise. In the event that Indemnitee is not wholly successful, on the merits
or otherwise, in a Proceeding but is successful, on the merits or otherwise, as
to any Claim in such Proceeding, the Corporation shall indemnify Indemnitee
against all Expenses actually and reasonably incurred by him or on his behalf
relating to each Claim. For purposes of this Section 4.1 and without limitation,
the termination of a Claim in a Proceeding by dismissal, with or without
prejudice, shall be deemed to be a successful result as to such Claim.

         Section 4.2 Expenses of a Witness. Notwithstanding any other provision
of this Agreement, to the extent that Indemnitee is, by reason of his Corporate
Status, a witness or otherwise participates in any Proceeding at a time when he
is not named a defendant or respondent in the


                                       -5-

   6


Proceeding, he shall be indemnified against all Expenses actually and reasonably
incurred by him or on his behalf in connection therewith.

         Section 4.3 Advancement of Expenses. The Corporation shall pay all
reasonable Expenses incurred by or on behalf of Indemnitee in connection with
any Proceeding or Claim, whether brought by the Corporation or otherwise, in
advance of any determination respecting entitlement to indemnification pursuant
to Article V hereof within 10 days after the receipt by the Corporation of a
written request from Indemnitee requesting such payment or payments from time to
time, whether prior to or after final disposition of such Proceeding or Claim.
Such statement or statements shall reasonably evidence the Expenses incurred by
Indemnitee. Indemnitee hereby undertakes and agrees that he will reimburse and
repay the Corporation for any Expenses so advanced to the extent that it shall
ultimately be expressly determined by a court in a final adjudication from which
there is no further right of appeal, that Indemnitee is not entitled to be
indemnified against such Expenses.

                                    ARTICLE V

                   PROCEDURE FOR DETERMINATION OF ENTITLEMENT
                               TO INDEMNIFICATION

         Section 5.1 Request by Indemnitee. To obtain indemnification under this
Agreement, Indemnitee shall submit to the Corporation a written request,
including therein or therewith such documentation and information as is
reasonably available to Indemnitee and is reasonably necessary to determine
whether and to what extent Indemnitee is entitled to indemnification. The
Secretary or an Assistant Secretary of the Corporation shall, promptly upon
receipt of such a request for indemnification, advise the Board in writing that
Indemnitee has requested indemnification.

         Section 5.2 Determination of Request. Upon written request by
Indemnitee for indemnification pursuant to the first sentence of Section 5.1
hereof, a determination, if required by applicable law, with respect to
Indemnitee's entitlement thereto, subject however to the provisions of Section
5.3, shall be made in the specific case in accordance with Section 145 of the
DGCL. If it is so determined that Indemnitee is entitled to indemnification
hereunder, payment to Indemnitee shall be made within 10 days after such
determination. Indemnitee shall cooperate with the Person making such
determination with respect to Indemnitee's entitlement to indemnification,
including providing to such Person upon reasonable advance request any
documentation or information that is not privileged or otherwise protected from
disclosure and that is reasonably available to Indemnitee and reasonably
necessary to such determination. Any costs or expenses (including attorneys'
fees and disbursements) incurred by Indemnitee in so cooperating with the Person
making such determination shall be borne by the Corporation (irrespective of the
determination as to Indemnitee's entitlement to indemnification) and the
Corporation hereby agrees to indemnify and hold harmless Indemnitee therefrom
and pay such costs and expenses within 10 days of receipt of written request for
such payment.

         Section 5.3 Independent Counsel. At Indemnitee's option, Indemnitee may
elect that the determination as to indemnification is to be made by Independent
Counsel, in which event the Independent Counsel shall be selected by Indemnitee,
and Indemnitee shall give written notice to the Corporation within 10 days
advising it of the identity of the Independent Counsel so selected (unless
Indemnitee shall request that such selection be made by the Board, in which
event the Corporation shall give written notice to Indemnitee within 10 days
after receipt of Indemnitee's request for indemnification advising him of the
identity of the Independent Counsel so selected). In either event, Indemnitee or
the Corporation, as the case may be, may, within seven days after such written
notice of selection shall have been given, deliver to the Corporation or to
Indemnitee, as the case may be, a written objection to such selection. Any
objection to selection of independent Counsel pursuant to this Section 5.3 may
be asserted only on the ground that the Independent Counsel so selected does not
meet the requirements of the definition of "Independent Counsel" in Article I
hereof, and the objection shall set forth with particularity the factual basis
of such assertion. If such written objection is timely made, the Independent
Counsel so selected may not serve as Independent Counsel unless and until a
court has determined that such objection is without merit. In the event of a
timely written objection to a choice of Independent Counsel, the party
originally selecting the Independent Counsel shall have seven days to make an
alternate selection of Independent Counsel and to give written notice of such
selection to the other party, after which time such other party shall have seven
days to make a written objection to such alternate selection. If, within 45 days
after submission by Indemnitee of a written request for indemnification pursuant
to Section 5.1 hereof, no Independent Counsel shall have been selected and not
objected to, either the Corporation or Indemnitee may petition a court of
competent Jurisdiction (the "Court") for resolution of any objection that shall
have been made by the Corporation or Indemnitee to the other's selection of
Independent Counsel and/or for the appointment as Independent Counsel of a
Person selected by the Court or by such other Person as the Court shall
designate, and the Person with respect to whom an objection is so resolved or
the Person so appointed shall act as Independent Counsel under Section 5.2
hereof. The Corporation shall pay any and all reasonable fees and expenses of
Independent Counsel incurred by such Independent Counsel in connection with
acting pursuant to hereto and provide such Person with appropriate
indemnification, and the Corporation shall pay all reasonable fees and expenses
incident to the procedures of this Section 5.3, regardless of the manner in
which such Independent Counsel was selected or appointed. Upon the due
commencement of any judicial proceeding or arbitration pursuant to Section
6.1(c) of this Agreement, Independent Counsel shall be discharged and relieved
of any further responsibility in such capacity (subject to the applicable
standards of professional conduct then prevailing).

         Section 5.4 Presumptions and Effect of Certain Proceedings.

         (a) The Indemnitee shall be presumed (except as otherwise expressly
provided in this Agreement) to be entitled to indemnification under this
Agreement upon submission of a request for indemnification under Section 5.1,
and thereafter the Corporation shall have the burden of proof in overcoming that
presumption in reaching a determination contrary to that presumption. The
presumption shall be used by Independent Counsel (or other Person or Persons
determining entitlement to indemnification) as a basis for a determination of
entitlement to indemnification


                                       -7-

   8


unless the Corporation provides information sufficient to overcome such
presumption by clear and convincing evidence.

         (b) If the Person or Persons empowered or selected under Article V of
this Agreement to determine whether Indemnitee is entitled to indemnification
shall not have made a determination within 60 days after receipt by the
Corporation of the request by Indemnitee therefor (or, if the determination of
entitlement to indemnification is to be made by Independent Counsel pursuant to
Section 5.3 of this Agreement, and such determination shall not have been made
and delivered in written opinion within 90 days after (i) such Independent
Counsel's being appointed, (ii) the overriding by the Court of objections to
such Counsel's selection or (iii) expiration of all periods for the Corporation
or Indemnitee to object to such Counsel's selection), the requisite
determination of entitlement to indemnification shall be deemed to have been
made and Indemnitee shall be entitled to such indemnification, absent a
prohibition of such indemnification under applicable law; provided, however,
that such 60-day period may be extended for a reasonable time, not to exceed an
additional 30 days, if the Person making the determination with respect to
entitlement to indemnification, in good faith requires such additional time for
the obtaining or evaluating of documentation and/or information relating to such
determination; and provided, further, that the 60-day limitation set forth in
this Section 5.4(b) shall not apply and such period shall be extended as
necessary if Independent Counsel is not to make the determination pursuant to
Section 5.3 of this Agreement and if within 30 days after receipt by the
Corporation of the request for indemnification under Section 5.1 the Board has
resolved to submit such determination to the shareholders for their
consideration at an annual meeting thereof to be held within 90 days after such
receipt and such determination is made thereat, or a special meeting of
shareholders is called within 30 days after such receipt for the purpose of
making such determination, such meeting is held for such purpose within 60 days
after having been so called and such determination is made thereat.

         (c) The termination of any Proceeding or of any Claim by judgment,
order, settlement or conviction, or upon a plea of nolo contendere or its
equivalent, shall not (except as otherwise expressly provided in this Agreement)
by itself adversely affect the right of Indemnitee to indemnification or create
a presumption that Indemnitee did not conduct himself in good faith and in a
manner that he reasonably believed in the case of conduct in his official
capacity, that was in the best interests of the Corporation or, in all other
cases, that was not opposed to the best interests of the Corporation or, with
respect to any criminal Proceeding, that Indemnitee had reasonable cause to
believe that his conduct was unlawful. Indemnitee shall be deemed to have been
found liable in respect of any Claim only after he shall have been so adjudged
by a court in competent jurisdiction after exhaustion of all appeals therefrom.

                                   ARTICLE VI

                         CERTAIN REMEDIES OF INDEMNITEE

         Section 6.1 Indemnitee Entitled to Adjudication in an Appropriate
Court. In the event (a) a determination is made pursuant to Article V that
Indemnitee is not entitled to indemnification under this Agreement or (b) there
has been any failure by the Corporation to make timely payment or advancement of
any amounts due hereunder, Indemnitee shall be entitled to commence an action
seeking an adjudication in an appropriate court of the State of Texas, or in any
other court of competent jurisdiction, of his entitlement to such
indemnification or advancement of Expenses. Alternatively, Indemnitee, at his
option, may seek an award in arbitration to be conducted by a single arbitrator
pursuant to the rules of the American Arbitration Association. Indemnitee shall
commence such action seeking an adjudication or an award in arbitration within
180 days following the date on which Indemnitee first has the right to commence
such action pursuant to this Section 6.1, or such right shall expire. The
Corporation agrees not to oppose Indemnitee's right to seek any such
adjudication or award in arbitration.

         Section 6.2 Adverse Determination Not to Affect any Judicial
Proceeding. In the event that a determination shall have been made pursuant to
Article V that Indemnitee is not entitled to indemnification, any judicial
proceeding or arbitration commenced pursuant to this Article VI shall be
conducted in all respects as a de novo trial or arbitration on the merits, and
Indemnitee shall not be prejudiced by reason of such determination. In any
judicial proceeding or arbitration commenced pursuant to this Article VI, the
Corporation shall have the burden of proving that Indemnitee is not entitled to
indemnification or advancement of Expenses, as the case may be.

         Section 6.3 Corporation Bound by Determination Favorable to Indemnitee
in any Judicial Proceeding or Arbitration. If a determination shall have been
made or deemed to have been made pursuant to Article V that Indemnitee is
entitled to indemnification, the Corporation shall be bound by such
determination in any judicial proceeding or arbitration commenced pursuant to
this Article VI.

         Section 6.4 Corporation Bound by the Agreement. The Corporation shall
be precluded from asserting in any judicial proceeding or arbitration commenced
pursuant to this Article VI that the procedures and presumptions of this
Agreement are not valid, binding and enforceable and shall stipulate in any such
court or before any such arbitrator that the Corporation is bound by all the
provisions of this Agreement.

         Section 6.5 Indemnitee Entitled to Expenses of Judicial Proceeding. In
the event that Indemnitee seeks a judicial adjudication of or an award in
arbitration to enforce his rights under, or to recover damages for breach of,
this Agreement, Indemnitee shall be entitled to recover from the Corporation,
and shall be indemnified by the Corporation against, any and all expenses (of
the types described in the definition of Expenses in Article I) actually and
reasonably incurred by him in such


                                       -9-
   10


judicial adjudication or arbitration but only if he prevails therein. If it
shall be determined in said judicial adjudication or arbitration that Indemnitee
is entitled to receive part but not all of the indemnification or advancement of
expenses or other benefit sought, the expenses incurred by Indemnitee in
connection with such judicial adjudication or arbitration shall be reasonably
prorated in good faith by counsel for Indemnitee. Notwithstanding the foregoing,
if a Change in Control shall have occurred, Indemnitee shall be entitled to
indemnification under this Section 6.5 regardless of whether Indemnitee
ultimately prevails in such judicial adjudication or arbitration.

                                   ARTICLE VII

                                  MISCELLANEOUS

         Section 7.1 Non-Exclusivity. The rights of Indemnitee to receive
indemnification and advancement of Expenses under this Agreement shall not be
deemed exclusive of any other rights to which Indemnitee may at any time be
entitled under applicable law, the Articles of Incorporation or Bylaws of the
Corporation, any other agreement, vote of shareholders or a resolution of
directors, or otherwise. No amendment or alteration of the Articles of
Incorporation or Bylaws of the Corporation or any provision thereof shall
adversely affect Indemnitee's rights hereunder and such rights shall be in
addition to any rights Indemnitee may have under the Corporation's Articles of
Incorporation, Bylaws and the DGCL or otherwise. To the extent that there is a
change in the DGCL (whether by statute or judicial decision) which allows
greater indemnification (including but not limited to any stronger procedural
protection) than would be afforded currently under the Corporation's Articles of
Incorporation or Bylaws and this Agreement, it is the intent of the parties
hereto that the Indemnitee shall enjoy by virtue of this Agreement the greater
benefit so afforded by such change without additional action on the part of
Indemnitee or the Corporation.

         Section 7.2 Insurance and Subrogation.

         (a) To the extent that the Corporation maintains an insurance policy or
policies providing liability insurance for directors, officers, employees,
agents or fiduciaries of the Corporation or of any other corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise
that such Person serves at the request of the Corporation, Indemnitee shall be
covered by such policy or policies in accordance with its or their terms to the
maximum extent of the coverage available for any such director, officer,
employee, agent or fiduciary under such policy or policies.

         (b) In the event of any payment by the Corporation under this
Agreement, the Corporation shall be subrogated to the extent of such payment to
all of the rights of recovery of Indemnitee, who shall execute all papers
required and take all action necessary to secure such rights, including
execution of such documents as are necessary to enable the Corporation to bring
suit to enforce such rights.

         (c) The Corporation shall not be liable under this Agreement to make
any payment of amounts otherwise indemnifiable hereunder if and to the extent
that Indemnitee has otherwise


                                      -10-

   11


actually received such payment under the Corporation's Articles of
Incorporation, or any Bylaw, insurance policy, contract, agreement or otherwise.

         Section 7.3 Self Insurance of the Corporation. The parties hereto
recognize that the Corporation may, but is not required to, procure or maintain
insurance or other similar arrangements, at its expense, to protect itself and
any Person, including the Indemnitee, who is or was a director, officer,
employee, agent or fiduciary of the Corporation or who is or was serving at the
request of the Corporation as a director, officer, partner, venturer,
proprietor, trustee, employee, agent or similar functionary of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise against any expense, liability or loss asserted against or incurred
by such Person, in such a capacity or arising out of his status as such a
Person, whether or not the Corporation would have the power to indemnify such
Person against such expense or liability.

         In considering the cost and availability of such insurance, the
Corporation, (through the exercise of the business of its directors and
officers), may from time to time, purchase insurance which provides for any and
all of (i) deductibles, (ii) limits on payments required to be made by the
insurer, or (iii) coverage exclusions and/or coverage which may not be as
comprehensive as that which might otherwise be available to the Corporation but
which otherwise available insurance the officers or directors of the Corporation
determine is inadvisable for the Corporation to purchase given the cost
involved. The purchase of insurance with deductibles, limits on payments and
coverage exclusions will be deemed to be in the best interest of the Corporation
but may not be in the best interest of the Indemnitee. As to the Corporation,
purchasing insurance with deductibles, limits on payments and coverage
exclusions is similar to the Corporation's self-insuring itself. In order to
protect Indemnitee who would otherwise be more fully or entirely covered under
such policies, the Corporation shall indemnify and hold Indemnitee harmless to
the extent (i) of such deductibles, (ii) of amounts exceeding payments required
to be made by an insurer or (iii) of coverage under policies of officer's and
director's liability insurance that are available, were available or which
became available to the Corporation or which are generally available to
companies comparable to the Corporation but which the officers or directors of
the Corporation determine is inadvisable for the Corporation to purchase, given
the cost involved. The obligation of the Corporation in the preceding sentence
shall be without regard to whether the Corporation would otherwise be entitled
to indemnify such officer or director under the other provisions of this
Agreement, or under any law, agreement, vote of shareholders or directors or
other arrangement. Notwithstanding the foregoing provisions of this Section 7.3,
the Indemnitee shall not be entitled to indemnification for the results of his
conduct that is intentionally adverse to the interests of the Corporation.
Without limiting the generality of any provision of this Agreement, the
procedures in Article V hereof shall, to the extent applicable, be used for
determining entitlement to indemnification under this Section 7.3. This
Agreement is authorized by Section 2.02-1(R) of the DGCL as in effect on January
19, 1999, and further is intended to establish an arrangement of self-insurance
pursuant to that section.

         Section 7.4 Exculpation of Directors. If Indemnitee is or was a
director of the Corporation, he shall not in that capacity be liable to the
Corporation or its shareholders for monetary


                                      -11-

   12


damages for an act or omission in Indemnitee's capacity as a director, except
that Indemnitee's liability shall not be eliminated or limited for: (a) a breach
of Indemnitee's duty of loyalty to the Corporation or its shareholders; (b) an
act or omission not in good faith that constitutes a breach of duty of the
director to the Corporation or an act or omission that involves intentional
misconduct or a knowing violation of the law; (c) a transaction from which
Indemnitee received an improper benefit, whether or not the benefit resulted
from an action taken within the scope of Indemnitee's office; or (d) an act or
omission for which the liability of Indemnitee is expressly provided for by
statute. If applicable law should in the future further limit the instances in
which Indemnitee may be so liable, this Section 7.4 shall automatically (without
the necessity of action by the Corporation or Indemnitee) be so limited.

         Section 7.5 Duration of Agreement. This Agreement shall continue for so
long as Indemnitee has Corporate Status and thereafter shall survive until
Indemnitee has ceased to have Corporate Status or for so long as Indemnitee
shall be subject to any possible Proceeding. This Agreement shall be binding
upon the Corporation and its successors and assigns and shall inure to the
benefit of Indemnitee and his heirs, executors, legal representatives and
administrators.

         Section 7.6 Amendment. This Agreement may not be modified or amended
except by a written instrument executed by or on behalf of each of the parties
hereto.

         Section 7.7 Waivers. The observance of any term of this Agreement may
be waived (either generally or in a particular instance and either retroactively
or prospectively) by the party entitled to enforce such term only by a writing
signed by the party against which such waiver is to be asserted. Unless
otherwise expressly provided herein, no delay on the part of any party hereto in
exercising any right, power or privilege hereunder shall operate as a waiver
thereof, nor shall any waiver on the part of any party hereto of any right,
power or privilege hereunder operate as a waiver of any other right, power or
privilege hereunder nor shall any single or partial exercise of any right, power
or privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, power or privilege hereunder.

         Section 7.8 Entire Agreement. This Agreement and the documents
expressly referred to herein constitute the entire agreement between the parties
hereto with respect to the matters covered hereby, and any other prior or
contemporaneous oral or written understandings or agreements with respect to the
matters covered hereby are expressly superseded by this Agreement.

         Section 7.9 Severability. If any provision of this Agreement (including
any provision within a single section, paragraph or sentence) or the application
of such provision to any Person or circumstance, shall be judicially declared to
be invalid, unenforceable or void, such decision will not have the effect of
invalidating or voiding the remainder of this Agreement or affect the
application of such provision to other Persons or circumstances, and the parties
hereto agree that the part or parts of this Agreement so held to be invalid,
unenforceable or void will be deemed to have been stricken herefrom and the
remainder of this Agreement will have the same force and effectiveness as if
such part or parts had never been included herein; provided, however, that the
parties shall negotiate in


                                      -12-
   13

good faith with respect to an equitable modification of the provision or
application thereof declared to be invalid, unenforceable or void. Any such
finding of invalidity or unenforceability shall not prevent the enforcement of
such provision in any other jurisdiction to the maximum extent permitted by
applicable law.

         Section 7.10 Notices. Unless otherwise expressly provided herein, all
notices, requests, demands, consents, waivers, instructions, approvals and other
