            (b) Further, income earned on the Escrow Fund shall be distributed

Agreement;

            (c) All disbursements hereunder pursuant to Section 5(a)(i) or
5(a)(ii) shall be made by the Escrow Agent within two (2) business days
following Escrow Agent's receipt of a Notice of Distribution, as contemplated in
Section 5(a) above.

      6. The Escrow Agent's Duties. The Escrow Agent shall be obligated to
perform only such duties as are expressly set forth in this Agreement, and shall
not be required, in carrying out its duties under this Agreement, to take notice
of or refer to any other document or agreement, including the Purchase
Agreement. The provisions of this Section 6 shall survive the resignation or
removal of the Escrow Agent or the termination of this Agreement.

      7. The Escrow Agent's Fees and Expenses. The Purchaser agrees to (i) pay
or reimburse the Escrow Agent for its attorney's fees and expenses incurred in
connection with the preparation of this Escrow Agreement, and (ii) pay the
Escrow Agent's compensation for its services hereunder in accordance with the
fee schedule attached hereto as Exhibit A and made a part hereof, which may be
subject to change hereafter by the Escrow Agent on an annual basis. The
Purchaser agrees to reimburse the Escrow Agent on demand for all costs and
expenses incurred in connection with the administration of this Escrow Agreement
or the escrow created hereby or the performance or observance of its duties
hereunder which are in excess of its compensation for normal services hereunder,
including without limitation payment of any legal fees and expenses incurred by
the Escrow Agent in connection with resolution of any claim by any party
hereunder.

      8. Provisions Relating To The Escrow Agent.

            (a) The Escrow Agent shall not be liable for any action or omission
hereunder, except for its own gross negligence or willful misconduct. Further,
except with respect to claims based upon such gross negligence or willful
misconduct that are successfully asserted against the Escrow Agent, Purchaser
agrees to indemnify and hold harmless the Escrow Agent and each of its officers,
directors, employees and agents (and any successor escrow agent) from and
against any and all losses, liabilities, claims, actions, damages and expenses,
including reasonable attorneys' fees and disbursements, arising directly or
indirectly out of or in connection with this Agreement or the Escrow Agent's
undertaking to serve as escrow agent hereunder. As between the parties hereto
other than the Escrow Agent, if Seller's acts or omissions give rise to the
above-mentioned indemnity obligation to the Escrow Agent, then Seller shall
reimburse Purchaser for any expense incurred by Purchaser in connection with the
indemnity of Escrow Agent. Without limiting the foregoing, the Escrow Agent
shall in no event be liable in connection with its investment or reinvestment of
any cash held by it hereunder in good faith, in accordance with the terms
hereof, including, without limitation, any liability for any delays (not
resulting from its own gross negligence or willful misconduct) in the investment
or reinvestment of the Escrow Fund, or any loss of interest incident to any such
delays.

            (b) Provided that the Escrow Agent acts in good faith, the Escrow
Agent shall be entitled to rely upon any order, judgment, certification, demand,
notice, instrument or other writing delivered to it hereunder without being
required to determine the authenticity or the

                                      -3-
<PAGE>

correctness of any fact stated therein or the propriety or validity of the
service thereof. The Escrow Agent may act in reliance upon any instrument or
signature believed by it in good faith to be genuine and provided that it
believes in good faith that the person executing such instrument has been
authorized to do so. The Escrow Agent may conclusively assume that the
undersigned representative of any party hereto which is an entity other than a
natural person has full power and authority to instruct the Escrow Agent on
behalf of that party unless written notice to the contrary is delivered to the
Escrow Agent.

            (c) The Escrow Agent may act pursuant to the advice of counsel with
respect to any matter relating to this Agreement and shall be fully protected
and not be liable for any action taken or omitted by it in good faith in
accordance with such advice.

            (d) Any payments of income from the Escrow Fund shall be subject to
withholding regulations then in force with respect to United States taxes. The
Seller will provide the Escrow Agent with appropriate Internal Revenue Service
Forms W-9 for tax identification number certification or non-resident alien
certifications. The Escrow Agent shall have no duty or obligation with respect
to the preparation or the filing of any report or return pertaining to any state
or Federal taxation. The Seller agrees that, for purposes of federal and state
income taxes, the Seller will report all income, if any, that is earned on, or
derived from, the Escrow Fund as its income in the taxable year or years in
which such income is properly includable and pay any taxes attributable thereto.

            (e) In the event of any disagreement between the Purchaser on the
one hand, and the Seller on the other hand, or any other dispute or disagreement
resulting in adverse claims or demands being made in connection with the Escrow
Fund or this Agreement or in the event that the Escrow Agent is in doubt as to
what action it should take hereunder, the Escrow Agent shall be entitled to (i)
retain the Escrow Fund until the Escrow Agent shall have received (A) a final
non-appealable order of an arbitrator or a court of competent jurisdiction
directing delivery of the Escrow Fund, or (B) Notice of Distribution directing
delivery of the Escrow Fund, in which event the Escrow Agent shall disburse the
Escrow Fund in accordance with such Notice of Distribution; or (ii) tender into
the registry or custody of any court of competent jurisdiction any part or all
of the Escrow Fund, in which case the Escrow Agent shall thereupon be discharged
from all further duties as escrow agent under this Agreement. Any court order
shall be accompanied by a legal opinion by counsel for the presenting party
reasonably satisfactory to the Escrow Agent to the effect that the order is
final and non-appealable. The Escrow Agent may rely conclusively and without
inquiry on the validity and genuineness of any such court order and opinion
furnished to the Escrow Agent and shall act in accordance with such court order
and legal opinion without further question.

            (f) The provisions of this Section 8 shall survive the resignation
or removal of the Escrow Agent or the termination of this Agreement.

      9. Resignation of the Escrow Agent. The Escrow Agent may at any time
resign as escrow agent hereunder by giving thirty (30) days' prior written
notice of resignation to the Purchaser and the Seller. Prior to the effective
date of the resignation as specified in such notice, the Purchaser and the
Seller will issue to the Escrow Agent joint written instructions directing
redelivery of all property held pursuant to this Agreement to a bank or trust
company which they

                                     - 4 -
<PAGE>

mutually select. If, however, the Purchaser and the Seller shall fail to name
such a successor escrow agent within twenty (20) days after the notice of
resignation from the Escrow Agent, the Escrow Agent may (i) apply to a court of
competent jurisdiction for appointment of a successor escrow agent, or (ii)
deposit all property held pursuant to this Agreement into the registry of a
court of proper jurisdiction, and in either such case the Escrow Agent shall
thereupon be relieved of any further obligation under this Agreement. Any such
successor escrow agent must agree to be and shall be bound by, and shall have
all the rights, duties and responsibilities of the Escrow Agent under this
Agreement. Such resignation shall not deprive the Escrow Agent of its
compensation earned prior to such resignation, the Escrow Agent's right to
reimbursement of expenses, or the Escrow Agent's rights to the indemnification
provided for in Section 8 hereof.

      10. Notices. All notices, consents, waivers, and other communications
under this Agreement must be in writing and will be deemed to have been duly
