parties hereto. No failure to exercise and no delay in exercising any right,
power or privilege shall operate as a waiver thereof, nor shall any single or
partial exercise of any right, power or privilege preclude the exercise of any
other right, power or privilege. No waiver of any breach of any covenant or
agreement hereunder shall be deemed a waiver of any preceding or subsequent
breach of the same or any other covenant or agreement. The rights and remedies
of each party under this Agreement are in addition to all other rights and
remedies, at law or in equity, that such party may have against the other
parties. Any waiver hereunder by the Shareholders shall be determined by a
majority in interest of the Shareholders.

         10.4 Procedure Regarding Shareholders Indemnification. Subject to the
terms of the Escrow Agreement:

              (a) Any claim for indemnification hereunder by Purchaser shall
first be made by Purchaser against the Escrow Fund, by giving written notice to
the Shareholder Representative (the "First Notice") and the Escrow Agent.

              (b) Any claim for indemnification brought by the Purchaser
pursuant to paragraphs 10.2(b)(ii), 10.2(b)(iii) and 10.2(b)(iv) hereunder
against the Shareholders (other than the Non-Management Employee Shareholders)
shall be borne jointly and severally by the Shareholders, other than the
Non-Management Employee Shareholders, based upon each such Shareholder's
interest in the Initial Escrow Funding. Any claim for indemnification brought by
the Purchaser pursuant to paragraphs 10.2(b)(i) and 10.2(b)(v) hereunder against
an individual Shareholder (other than a Non-Management Employee Shareholder)
shall be borne solely by such individual Shareholder based upon such
Shareholder's interest in the Initial Escrow Funding. Any claim for
indemnification brought by the Purchaser against a Non-Management Employee
Shareholder with respect to such Non-Management Employee Shareholder's specific
representations and warranties set forth in Article 3 hereof and the covenants
made severally by such Non-Management Employee Shareholder, shall be borne
solely by such individual Non-Management Employee Shareholder and not by the
Escrow Fund.

              (c) Provided indemnification claims have not exceeded the Initial
Escrow Funding and no indemnification claims are outstanding, the Initial Escrow
Funding shall be reduced to $1,361,926 (the "Reduced Escrow Funding"), on the
first anniversary of the Closing Date (or if an indemnification claim is
outstanding, as soon thereafter as such claim is resolved) until the second
anniversary of the Closing Date. Any funds in excess of the Reduced Escrow
Funding on the first anniversary of the Closing Date (or if an indemnification
claim is outstanding, as soon thereafter as such claim is resolved) shall be
returned to the Shareholder Representative, who shall distribute such funds to
the Shareholders, other than the Non-Management Employee Shareholders, based
upon each Shareholder's interest in the Initial Escrow Funding.

              (d) Except as provided in paragraph (h) of this Section 10.4, on
the second anniversary of the Closing Date (or if an indemnification claim is
outstanding, as soon thereafter as such claim is resolved) (the "Escrow
Termination Date"), any funds remaining in the Escrow Fund shall be returned to
the

                                     - 50 -

<PAGE>



Shareholder Representative, who shall distribute such funds to the Shareholders,
other than the Non-Management Employee Shareholders, based upon each such
Shareholder's interest in the Initial Escrow Funding.

              (e) To the extent any claim for indemnification pursuant to
paragraph (a) of this Section 10.4 is unsatisfied or with regard to any
indemnification claim made after the Escrow Termination Date (solely with
respect to the representations and warranties set forth in Article 3 hereof),
Purchaser shall seek indemnification hereunder through written notice to the
Shareholder Representative (the "Second Notice"). If the claim for
indemnification brought by the Purchaser is pursuant to paragraphs 10.2(b)(ii),
10.2(b)(iii) and 10.2(b)(iv) such indemnification shall be borne jointly and
severally by the Shareholders (other than the Non-Management Employee
Shareholders, who shall only be responsible for their Article 3 representations
and warranties and their covenants, severally and not jointly), on the basis of
each such Shareholder's interest in the Initial Escrow Funding. If the claim for
indemnification brought by the Purchaser pursuant to paragraphs 10.2(b)(i) and
10.2(b)(v) such indemnification shall be borne solely by such individual
Shareholder (other than the Non-Management Employee Shareholders) based upon
such Shareholder's interest in the Initial Escrow Funding.

              (f) If after thirty (30) days of the Second Notice any part of the
indemnification claim remains unsatisfied, the Purchaser shall seek
indemnification payment relating to the unsatisfied indemnification claim
hereunder through written notice to the Shareholder Representative (the "Second
Notice"). If the claim for indemnification was pursuant to paragraphs
10.2(b)(ii), 10.2(b)(iii), or 10.2(b)(iv), such indemnification shall be paid
jointly and severally by the Shareholders (other than the Non-Management
Employee Shareholders, who shall only be responsible for their Article 3
representations and warranties and their covenants severally and not jointly),
on the basis of each such Shareholder's interest in the Initial Escrow Funding
exclusive of any interest attributable to any Shareholder who has not paid his
proportionate share of the indemnification claim pursuant to paragraph 10.4(a)
above.

              (g) If any part of the indemnification claim in paragraph 10.2(f)
(other than a claim against an individual Shareholder pursuant to paragraphs
10.2(b)(i) and 10.2(b)(v), which shall be borne severally by such individual
Shareholder) remains unsatisfied thirty (30) days after the Third Notice, the
Purchaser shall be entitled to indemnification from the Shareholders, other than
the Non-Management Employee Shareholders, jointly and severally.

                                     - 51 -

<PAGE>




              (h) Should any Schedule 4.11 Matter remain outstanding on the
second anniversary of Closing Date the Shareholder Representative (subject to
Section 10.7) and the Purchaser shall mutually and reasonably agree upon the
amount to remain in the Escrow Fund and the duration such funds shall remain
therein. Any funds in excess of such amount shall be returned to the Shareholder
Representative, who shall distribute such funds to the Shareholders, other than
the Non-Management Employee Shareholders, based upon each such Shareholder's
interest in the Initial Escrow Funding. Thereafter, the Shareholders shall have
no liability in excess of the amount agreed upon hereunder. The funds remaining
in the Escrow Fund shall not be distributed unless and until all Schedule 4.11
matters are resolved.

         10.5 Third Party Claims.

              (a) If any party entitled to be indemnified pursuant to Section
10.2 (an "Indemnified Party") receives notice of the assertion by any third
party to any claim or of the commencement by any such third person of any Action
(any such claim or Action being referred to herein as an "Indemnifiable Claim")
with respect to which another party hereto (an "Indemnifying Party") is or may
be obligated to provide indemnification, the Indemnified Party shall promptly
notify the Indemnifying Party in writing (the "Claim Notice") of the
Indemnifiable Claim; provided, that the failure to provide such notice shall not
relieve or otherwise affect the obligation of the Indemnifying Party to provide
indemnification hereunder, except to the extent that any Damages directly
resulted or were caused by such failure.

              (b) The Indemnifying Party shall have thirty days after receipt of
the Claim Notice to undertake, conduct and control, through counsel of its own
choosing, and at its expense, the settlement or defense thereof, and the
Indemnified Party shall cooperate with the Indemnifying Party in connection
therewith; provided, that (i) the Indemnifying Party shall permit the
Indemnified Party to participate in such settlement or defense through counsel
chosen by the Indemnified Party (subject to the consent of the Indemnifying
Party, which consent shall not be unreasonably withheld), provided that the fees
and expenses of such counsel shall not be borne by the Indemnifying Party, and
(ii) the Indemnifying Party shall not settle any Indemnifiable Claim without the
Indemnified Party's consent. So long as the Indemnifying Party is vigorously
contesting any such Indemnifiable Claim in good faith, the Indemnified Party
shall not pay or settle such claim without the Indemnifying Party's consent,
which consent shall not be unreasonably withheld.

                                     - 52 -

<PAGE>




              (c) If the Indemnifying Party does not notify the Indemnified
Party within thirty days after receipt of the Claim Notice that it elects to
undertake the defense of the Indemnifiable Claim described therein, the
Indemnified Party shall have the right to contest, settle or compromise the
Indemnifiable Claim in the exercise of its reasonable discretion; provided, that
the Indemnified Party shall notify the Indemnifying Party of any compromise or
settlement of any such Indemnifiable Claim.

              (d) Anything contained in this Section 10.3 to the contrary
notwithstanding, the Shareholders shall not be entitled to assume the defense
for any Indemnifiable Claim (and shall be liable for the reasonable fees and
expenses incurred by the Indemnified Party in defending such claim) if the
Indemnifiable Claim seeks an order, injunction or other equitable relief or
relief for other than money damages against Purchaser or the Company which
Purchaser determines, after conferring with its counsel, cannot be separated
from any related claim for money damages and which, if successful, would
adversely affect the business, properties or prospects of the Company.

         10.6 Sole and Exclusive Remedy. The indemnification provided under this
Article 10 shall constitute the sole and exclusive remedy of the Shareholders,
the Company and the Purchaser subsequent to the Closing for any Damages
sustained by the Shareholders, the Company or the Purchaser as a result of any
breach of this Agreement other than any Damages based upon proven fraud, or
intentional misrepresentation or criminal matters.

         10.7 Shareholder Representative.

              (a) Shareholder Representative. Each Shareholder hereby designates
and appoints Robert J. Beaury (the "Shareholder Representative") as
representative for each Shareholder to perform all such acts as are required,
authorized or contemplated by this Article 10 to be performed by any such Person
and hereby acknowledges that the Shareholder Representative shall be the only
Person authorized to take any action so required, authorized or contemplated by
this Article 10 by such Person. Each such Person further acknowledges that the
foregoing appointment and designation shall be deemed to be coupled with an
interest and shall survive the death or incapacity of such Person. Such Person
hereby authorizes the other parties hereto to disregard any notice or other
action taken by such Person pursuant to this Article 10 except for the
Shareholder Representative. The other parties hereto are and will be entitled to
rely on any action so taken or any notice

                                     - 53 -

<PAGE>



given by the Shareholder Representative and are and will be entitled and
authorized to give notices only to the Shareholder Representative for any notice
contemplated by this Article 10 to be given to any such Person. Notwithstanding
the foregoing, the Shareholder Representative agrees that, before taking any
action that would adversely affect any Shareholder, the Shareholder
Representative shall give notice to and obtain consent from each Shareholder. In
the event the Shareholder Representative ceases to own Common Stock of the
Company or dies, a successor to the Shareholder Representative may be chosen by
a majority in interest of the Common Stock held by the Shareholders, provided
that notice thereof is given by the new Shareholder Representative to the
Company and the Purchaser.

         11.4 Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of Purchaser and the Shareholders and their respective

         11.8 Governing Law. This Agreement shall be governed by and construed
in accordance with the internal laws (without giving effect to the conflict of
laws principles thereto) of the Commonwealth of Pennsylvania.

         11.9 Arbitration.

              (a) Any controversy or claim arising out of or relating to this
Agreement, any transaction contemplated hereunder or any certificate, document
or instrument provided pursuant hereto, or the breach thereof, whether common
law or statutory, shall be settled exclusively by arbitration in Philadelphia,
Pennsylvania using the American Arbitration Association. The arbitration shall
be heard before three arbitrators, one to be chosen by the Company, one to be
chosen by the Purchaser and the third to be chosen by those two arbitrators.

              (b) The arbitrators shall apply the law of Pennsylvania applicable
to contracts made and to be performed entirely in such state (without giving
effect to the conflicts of laws provisions thereof) in determining the rights,
obligations and liabilities of the parties. The arbitrators shall not have the
power to alter, modify, amend, add to or subtract from any term or provision of
this Agreement, nor to grant injunctive relief, including interim relief, of any
nature. In all other respects, the commercial rules of the American Arbitration
Association shall govern the arbitration. Judgment on the award of the
arbitrators may be entered by any court having jurisdiction to do so, and each
party hereto hereby irrevocably consents and submits to the personal
jurisdiction of the federal and state courts of Pennsylvania for that purpose.

              (c) The failure or refusal of any party to submit to arbitration
shall constitute a breach of this Agreement. Judicial action may be commenced in
order to compel arbitration. If such action is commenced and if arbitration is
in fact compelled, the party that shall have resisted arbitration shall be
required to pay to the other parties all costs and expenses, including, without
limitation, reasonable attorneys' fees, that they incur in compelling
arbitration. The prevailing party in arbitration shall be entitled to its
reasonable attorneys' fees and costs.

         11.10 Disclosure Schedules. Items required to be disclosed on the
Disclosure Schedules under Article 4 shall be deemed to be disclosed therein for
all purposes of Article 4 irrespective of whether they are disclosed with
reference to all of the specific subsections to which they relate.
