Incorporated, a Delaware corporation (the "Purchaser"),
Commonwealth Overseas Trading Company Limited, a Bermuda
corporation (the "Seller"), Sheik Mohammed A. Al-Tuwaijri (the

"Escrow Agent").

WITNESSETH:

     WHEREAS, the Purchaser, the Seller and the Shareholder have
entered into that certain Stock Purchase Agreement dated as of
March 20, 1996, as amended (the "Purchase Agreement") with respect
to the purchase by the Purchaser and the sale by the Seller of all
of the issued and outstanding capital stock of WMF Holdings Ltd.,
a Delaware corporation (the "Company");

     WHEREAS, an aggregate of 210,000 shares of common stock, par
value $.01 per share of the Purchaser (together with any
additional securities and instruments identified in Section 2.2(a)
and (b) hereof, the "NHPI Shares"), constructively received by the
Seller pursuant to the Purchase Agreement, are to be deposited
with the Escrow Agent subject to the terms and conditions of this
Escrow, as security for the indemnification obligations of the
Seller and the Shareholder under the Purchase Agreement; and

     WHEREAS, pursuant to Section 2.4 of the Purchase Agreement,
the parties thereto agreed to enter into an Escrow with the Escrow
Agent containing the provisions hereinafter set forth.

     NOW, THEREFORE, in consideration of the premises and for
other good and valuable consideration, the receipt and sufficiency
of which are acknowledged by each of the parties hereto, the
parties hereby agree as follows:

     1.   DEFINED TERMS.  All capitalized terms used but not
defined in this Escrow shall have the respective meanings ascribed
to such terms in the Purchase Agreement.

     2.   ESTABLISHMENT OF ESCROW; PURPOSE OF ESCROW.

          2.1  Simultaneously with the execution and delivery of
this Escrow, the Purchaser, pursuant to the instructions of the
Seller and in accordance with the Purchase Agreement, is
delivering to and depositing with the Escrow Agent the NHPI
Shares, issued in the name of the Seller, as holder of record,
comprising a portion of the Purchase Price payable under the
Purchase Agreement, together with stock powers in blank duly
executed by the Seller.

          2.2  Seller hereby agrees that the address of the Seller
on the stock ledger of the Purchaser (and any transfer agent of
the Purchaser's securities) with respect to any NHPI Shares or
other securities held in the Escrow Fund (as hereinafter defined)
shall

 2
be recorded as "care of" the Escrow Agent, which address may only
be changed upon the express written instructions of the Escrow
Agent.  If at any time and from time to time following the
execution of this Escrow the Seller shall become entitled to
receive, in connection with any of the NHPI Shares held in the
Escrow Fund, any:

               (a)  stock certificate, including, without
limitation, any certificate representing a stock dividend or in
connection with any increase or reduction of capital,
reclassification, merger, consolidation, sale of assets,
combination of shares, stock split, spin-off of split-off; or

               (b)  option, warrant, right, or other security
whether as an addition to or in substitution of or in exchange for
any of such NHPI Shares or otherwise;

then, the Seller hereby agrees and directs the Purchaser to
deliver the same to the Escrow Agent and the Seller hereby
covenants and agrees to deliver to the Escrow Agent, at the Escrow
Agent's request, appropriate endorsement when necessary, or
appropriate stock powers duly executed in blank, together with any
documentary tax stamps and any other documents necessary to cause
the Escrow Agent to have, for the benefit of the Purchaser, a
good, valid and perfected first pledge of, lien on and security
interest in the NHPI Shares, free and clear of any mortgage,
pledge, lien, security interest, hypothecation, assignment,
charge, right or encumbrance (collectively, an "Encumbrance").
The Escrow Agent shall promptly notify the Seller upon its receipt
of any of said certificates or other securities.  In the event
that the Seller shall receive any of said certificates or other
securities, the Seller hereby agrees and covenants that it shall
accept the same as the Escrow Agent's agent, in trust for the
Escrow Agent (as part of the Escrow Fund), and shall deliver the
same immediately to the Escrow Agent, in the exact form received,
with the appropriate endorsement when necessary, or appropriate
stock powers duly executed in blank, together with any documentary
tax stamps and any other documents necessary to cause the Escrow
Agent to have, for the benefit of the Purchaser, a good, valid and
perfected first pledge of, lien on and security interest in the
NHPI Shares, free and clear of any Encumbrance.

          2.3  The Escrow Agent hereby acknowledges receipt of the
Escrow Fund and agrees to hold (i) the NHPI Shares and (ii) any
dividends or other distributions thereon or substitutions
therefor, whether payable in the form of cash, securities,
instruments or other property or assets (collectively, the "Escrow
Fund"), and to invest any proceeds therefrom and disburse the
Escrow Fund for the benefit of the Purchaser, the Seller and the
Shareholder and their respective legal representatives, successors
and assigns as provided herein.  All interest and other earnings
on the Escrow Fund shall be added to and shall constitute a part
of the Escrow Fund and shall be held and disbursed only as herein
permitted and provided.  The Escrow Agent shall hold the Escrow
Fund in a separate escrow account.

          2.4  The Escrow Fund is being deposited with the Escrow
Agent to assure that funds will be available, in an amount equal
to the Escrow Fund and interest and other earnings thereon, to
meet certain indemnification obligations of the Seller and the

 3
Shareholder under the Purchase Agreement as more particularly set
forth therein and herein.  In order to secure the Seller's and the
Shareholder's full and timely payment of such indemnification
obligations, the Seller and the Shareholder each hereby pledges,
assigns, hypothecates, transfers, delivers and grants to the
Purchaser a first priority security interest in and to all of the
Seller's and the Shareholder's present and future right, title and
interest in and to the Escrow Fund, together with all accrued
interest thereon and all proceeds thereof and amounts with the
same fair value in substitution therefor, free and clear of any
Encumbrance.

          2.5  The Escrow Agent shall hold the Escrow Fund in
escrow in accordance with and subject to the terms and provisions
of this Escrow and shall invest the same and make disbursements
therefrom only as herein permitted and provided.

     3.   INVESTMENT OF ESCROW FUND.  The Escrow Agent shall
invest any proceeds of the NHPI Shares constituting a portion of
the Escrow Fund only in Permitted Investments as directed in
writing by the mutual consent of the Purchaser and the Seller.
For the purposes of this Escrow, the term "Permitted Investments"
shall mean:  certificates of deposit issued by banks or trust
companies having in each case a combined capital and surplus of
not less than $50 million, United States Overnight Repurchase
Agreements, or money market funds consisting of debt instruments
of the United States or its agencies.  The Escrow Agent shall not
incur any liability in acting in good faith in making investments
authorized herein.

     4.   NOTICE OF CLAIM.  Purchaser may submit a notice to the
Escrow Agent at any time that Purchaser believes that it has
identified a breach of a Representation and Warranty indemnifiable
under the Purchase Agreement (a "Notice of Claim"), which notice
may precede the filing of any claim or action against the Seller
or the Shareholder.

     5.   DISBURSEMENTS FROM ESCROW FUND.

          5.1  BASIS FOR DISBURSEMENTS.  Disbursements from the
Escrow Fund shall be made from time to time by the Escrow Agent to
reimburse the Purchaser for losses and damages arising from
breaches of Representations and Warranties and to pay to the
Purchaser amounts due in respect of the indemnification
obligations of the Seller and the Shareholder pursuant to Articles
XI and XII of the Purchase Agreement and for Adjustment Period
Interest thereon, subject to the threshold limitations of Section
2.6 of the Purchase Agreement, where applicable.

          5.2  PAYMENT NOTICE.  Disbursements from the Escrow Fund
shall be made only after the submission to the Escrow Agent by the
Purchaser of a payment notice (the "Payment Notice") which shall
set forth in reasonable detail the basis upon which the
Purchaser's claim of entitlement to a payment pursuant to Article
XI and XII and Section 2.6 (to the extent applicable) of the
Purchase Agreement is predicated, together with the computations
in respect of the calculation of the amount thereof.  In the event
that the Purchaser files a Payment Notice prior to the filing of
any Notice of Claim with respect to the same claim of entitlement,
such Payment Notice shall constitute a Notice of Claim for the
purpose of Section 12.5 of the Purchase Agreement.

 4
          5.3  MEASUREMENT OF DAMAGES.  In the event that the
Purchaser suffers losses, claims, damages, liabilities, costs,
counsel fees and/or other expenses for which the Purchaser is
entitled to indemnification pursuant to Article XI, Article XII
and/or Section 2.6 (to the extent applicable) of the Purchase
Agreement, the amount of such indemnity shall be based on the
actual loss incurred by the Company and/or the Purchaser;
PROVIDED, that with respect to losses related to loan servicing by
the Company, such amount shall equal the greater of (i) the actual
loss incurred or (ii) the value assigned to the servicing rights
in question by the Purchaser, in accordance with generally
accepted accounting principles, in its initial financial
statements prepared following the Closing Date.

          5.4  DISBURSEMENT PROCEDURE.  The following procedures
shall be observed in connection with the making of disbursements
from the Escrow Fund.

               (a)  The Purchaser shall simultaneously furnish
copies of each Payment Notice to each of the Escrow Agent, the
Seller and the Shareholder.  Unless the Escrow Agent receives a
notice from the Seller or the Shareholder objecting to the making
of the payment to which the Purchaser claims to be entitled and
setting forth with reasonable particularity the basis of such
objection (an "Objection Notice") within fifteen Business Days
after the Escrow Agent's receipt of a Payment Notice (the
"Objection Period"), the Escrow Agent shall, within ten Business
Days after the end of the Objection Period, disburse from the
Escrow Fund and transfer (in the case of stock) and pay (in all
other respects) to the Purchaser the amount claimed to be due as
set forth in the Payment Notice pursuant to the valuation
procedures in Section 5.5 of this Escrow.  A copy of any Objection
Notice submitted by the Seller or the Shareholder to the Escrow
Agent shall be simultaneously submitted by the Seller or the
Shareholder, as the case may be, to the Purchaser.

               (b)  If the Escrow Agent receives an Objection
Notice within the Objection Period, it shall not make the
disbursement demanded in the Payment Notice until it receives (i)
a written instruction signed by the Purchaser and either the
Seller or the Shareholder directing that the disbursement be made
(either in the amount originally set forth in the Payment Notice
or in a modified amount), (ii) a copy of an order of a court
having jurisdiction over the parties and the matter, which order
shall have become final and not subject to further appeal, or
(iii) a copy of a determination of the issue by arbitrators
appointed by the Purchaser and the Seller and/or the Shareholder.
The Escrow Agent shall fully comply with the terms of any such
written instruction, order or determination as promptly as shall
be practicable.

               (c)  If it shall be determined by a court or by
arbitrators appointed by the Purchaser and the Seller and/or the
Shareholder that any (i) Notice of Claim or Payment Notice
submitted to the Escrow Agent by the Purchaser or (ii) Objection
Notice submitted to the Escrow Agent by the Seller and/or the
Shareholder fails to meet the standard required of pleadings and
motions

 5
pursuant to Rule 11 of the Federal Rules of Civil Procedure, then
the Seller (in the case of a Notice of Claim or Payment Notice) or
the Purchaser (in the case of a Objection Notice) shall be
entitled to receive from the Escrow Fund, as liquidated damages to
compensate it for the costs and damages incurred as a result of
being forced to litigate or arbitrate a claim, cash or other
assets valued at One Hundred Thousand Dollars ($100,000).  The
Purchaser, the Seller and the Shareholder acknowledge that the
actual amount of damages that would be incurred as a result of the
assertion of any such claim would be difficult or impossible to
ascertain and that the amount specified herein as liquidated
damages constitutes a reasonable estimate of the amount of such
damages.

          5.5  VALUATION PROCEDURE.  In the event that the
Purchaser is entitled to a certain amount of disbursals from the
Escrow Fund (the "Disbursal Amount"), the Escrow Agent shall
observe the following procedures:

               (a)  The Escrow Agent shall first disburse any cash
or cash equivalents held in the Escrow Fund, up to the Disbursal
Amount.

               (b)  If the amount of cash or cash equivalents held
in the Escrow Fund is less than the Disbursal Amount, the Escrow
Agent shall determine the number of NHPI Shares necessary to make
up such shortfall, based on the then current market price per
share of NHPI Common Stock, as reported on the Nasdaq Stock Market
at the close of trading on the Business Day prior to such
determination (or other securities exchange on which such shares
are then trading), and shall, subject to the provisions of Section
5.5(c) hereof, disburse such NHPI Shares to NHPI.

               (c)  Upon a determination that NHPI Shares are to
be disbursed to the Purchaser pursuant to Section 5.5(b) hereof,
prior to such disbursal the Escrow Agent shall notify the Seller
and the Shareholder of the number of NHPI Shares to be disbursed
and the aggregate value determined for such shares.  Within five
Business Days of the Escrow Agent's delivery of such notice, the
Seller and/or the Shareholder may, at their option, wire transfer
immediately available funds to the Escrow Agent in the amount set
forth on such notice, in which case, upon the receipt of such
funds in the Escrow Fund, the Escrow Agent shall release the
number of NHPI Shares identified in such notice to the Seller and
shall disburse the exchanged funds to the Purchaser.

     6.   TERM OF ESCROW; RELEASE OF ESCROW FUND; TERMINATION.

          6.1  This Escrow shall be and remain in full force and
effect until the third anniversary of the Closing Date (the
"Escrow Termination Date").

          6.2  On the first anniversary of the Closing Date, or,
if such anniversary is not a Business Day, on the first Business
Day next succeeding such date, the Escrow Agent shall release to
the Seller that amount of NHPI Shares held in the Escrow Fund
which

 6
exceeds 105,000 NHPI Shares, or in the event that fewer than
105,000 NHPI Shares are then held in the Escrow Fund, that amount
of assets which exceeds the then current market value of 105,000
NHPI Common Shares (determined pursuant to Section 5.5(b) hereof).

          6.3  On the second anniversary of the Closing Date, or,
if such anniversary is not a Business Day, on the first Business
Day next succeeding such date, the Escrow Agent shall release to
the Seller that amount of NHPI Shares held in the Escrow Fund
which exceeds 52,500 NHPI Shares, or in the event that fewer than
52,500 NHPI Shares are then held in the Escrow Fund, that amount
of assets which exceeds the then current market value of 52,500
NHPI Common Shares (determined pursuant to Section 5.5(b) hereof).

          6.4  On the Escrow Termination Date, or, if the Escrow
Termination Date shall not be a Business Day, on the first
Business Day next succeeding the Escrow Termination Date, the
Escrow Agent shall disburse the then remaining balance in the
Escrow Fund to the Seller.

          6.5  For the purposes of the calculations in Section 6.2
and 6.3 hereof (i) the Escrow Fund shall exclude any Disbursal
Amount and (ii) the threshold number of NHPI Shares identified in
each section shall be adjusted proportionately in the event of any
stock splits or stock dividends by the Purchaser from and after
the Closing Date.

     7.   VOTING RIGHTS, ETC.  The Escrow Agent shall provide
appropriate notices to the Seller and Seller shall exercise any
and all voting rights pertaining to the NHPI Shares which at any
time may be held in the Escrow Fund; UNLESS a claim identified in
a Notice of Claim or Payment Notice filed by the Purchaser has not
been resolved, in which event, without further notice and whether
or not the NHPI Shares shall have been registered in the name of
the Escrow Agent or its nominee, the Seller shall have no right to
direct the voting of the NHPI Shares then held in the Escrow Fund,
or any other corporate rights or any conversion, exchange,
subscription or other rights, privileges or options pertaining
thereto.  The Escrow Agent shall not vote the NHPI Shares held in
this Escrow Fund and shall not exercise any other rights.

     8.   ESCROW AGENT PROTECTIVE PROVISIONS.

          8.1  The duties of the Escrow Agent shall be solely as
set forth in this Escrow.  The Escrow Agent's duties and
obligations shall be purely ministerial and not discretionary;
such duties and obligations shall be determined solely by the
express provisions of this Escrow, and the Escrow Agent shall have
no obligation to refer to any other documents or agreements
between or among the parties related in any way to the Purchase
Agreement, regardless of whether it has knowledge of the
provisions of such other agreements. The Escrow Agent is to be
considered and regarded as a depository only and shall not be
responsible or liable (except for its gross negligence or willful
misconduct) for the sufficiency or correctness as to form, manner
of execution, or

 7
validity of any instrument deposited with the Escrow Agent, nor as
to the identity, authority, or rights of any person executing the
same.  The Escrow Agent's duties hereunder shall be limited to the
safekeeping and investment of the Escrow Fund and for its
disbursement in accordance with the provisions of this Escrow.
The Escrow Agent may consult counsel satisfactory to it, including
in-house counsel, and the opinion of such counsel shall be full
and complete protection in respect of any action taken, suffered
or omitted by it hereunder in good faith and in accordance with
the opinion of such counsel.

          8.2  The Escrow Agent shall not incur any liability in
acting upon any signature, notice, request, waiver, consent,
receipt or other paper or document believed by the Escrow Agent to
be genuine, and the Escrow Agent may assume that any person
purporting to give the Escrow Agent any notice on behalf of  any
party in accordance with the provisions hereof has been duly
authorized to do so.

          8.3  In the event of the death of any person who may be
a party in interest hereunder, the Escrow Agent shall deem and
treat the legal representative of such person's estate as the
successor in interest of said deceased person for all purposes of
this Escrow.

          8.4  It is expressly understood that the Escrow Agent is
not responsible or liable in any manner whatsoever for the
sufficiency, correctness, genuineness or validity of any
instrument deposited with the Escrow Agent or for the form of
execution of such instruments, or for the identity, authority or
right of any person executing or depositing the same, or for the
terms and conditions of any instrument pursuant to the Escrow
Agent or the other parties hereto may act.

          8.5  Subject to Section 3 hereof, the Escrow Agent shall
not be responsible for any act or failure to act and shall have no
liability under this Escrow or in connection herewith except in
the case of its own willful misconduct or gross negligence.

          8.6  Subject to Section 3 hereof, neither the Escrow
Agent nor any of its directors, officers, or employees shall be
liable to anyone for any action taken or omitted to be taken by it
or any of its directors, officers or employees hereunder except in
the case of gross negligence or willful misconduct.  Each of the
Purchaser, the Seller and the Shareholder, jointly and severally,
covenant and agree to indemnify the Escrow Agent and hold it
harmless without limitation from and against any loss, liability
or expense of any nature incurred by the Escrow Agent arising out
of or in connection with this Escrow or with the administration of
its duties hereunder, including, but not limited to reasonable
legal fees and other reasonable costs and expenses of defending or
preparing to defend against any claim or liability in the
premises, unless such loss, liability or expense shall be caused
by the Escrow Agent's willful misconduct or gross negligence.  In
no event shall the Escrow Agent be liable for indirect, punitive,
special or consequential damage.

 8
          8.7  Subject to Section 3 hereof, the Escrow Agent shall
not be responsible for any  diminution of monies deposited with
the Escrow Agent except to the extent that such loss arises out of
gross negligence or willful misconduct of the Escrow Agent.

          8.8  The Purchaser, the Seller and the Shareholder,
jointly and severally, agree to assume any and all obligations
imposed now or hereafter by any applicable tax law with respect to
the payment of Escrow Funds under this Escrow, and to indemnify
and hold the Escrow Agent harmless from and against any taxes,
additions for late payment, interest, penalties and other
expenses, that may be assessed against the Escrow Agent on any
such payment or other activities under this Escrow.  Each of the
Purchaser, the Seller and the Shareholder undertake to instruct
the Escrow Agent in writing with respect to the Escrow Agent's
responsibility for withholding and other taxes, assessments or
other governmental charges, certifications and governmental
reporting in connection with its acting as Escrow Agent under this
Escrow.  The Purchaser, the Seller and the Shareholder, jointly
and severally, agree to indemnify and hold the Escrow Agent
harmless from any liability on account of taxes, assessments or
other governmental charges, including without limitation the
withholding or deduction or the failure to withhold or deduct
same, and any liability for failure to obtain proper
certifications or to properly report to governmental authorities,
to which the Escrow Agent may be or become subject in connection
with or which arises out of this Escrow, including costs and
expenses (including reasonable legal fees), interest and
penalties.  Notwithstanding the foregoing, no distributions will
be made unless the Escrow Agent is supplied with an original,
signed W-9 form or its equivalent prior to distribution.

          8.9  The Escrow Agent shall have no more or less
responsibility or liability on account of any action or omission
of any book-entry depository or subescrow agent employed by the
Escrow Agent than any such book-entry depository or subescrow has
to the Escrow Agent, except to the extent that such action or
omission of any book-entry depository or subescrow agent was
caused by the Escrow Agent's own gross negligence or bad faith.

          8.10 In case of conflicting demands upon the Escrow
Agent, it may (i) refuse to comply therewith as long as such
disagreement continues and make no delivery or other disposition
of any funds or property then held (and the Escrow Agent shall not
be or become liable in any way for such failure or refusal to
comply with such conflicting or adverse claims or demands); (ii)
continue to so refrain and so refuse to act until all differences
have been adjusted by agreement and the Escrow Agent has been
notified thereof by joint written instructions of the Purchaser,
the Seller and the Shareholder, or (iii) interplead the portion of
the Escrow Fund in dispute with the Clerk of the Superior Court of
the District of Columbia.

          8.11 The Escrow Agent may resign as Escrow Agent by
giving each of the Purchaser, the Seller and the Shareholder
twenty (20) Business Days written notice of its intention to
resign. Prior to the effective date of the resignation as
specified in such notice, the Purchaser will issue to the Escrow
Agent a written instruction authorizing redelivery of the Escrow
Funds to a bank or trust company that it selects subject to the

 9
reasonable consent of the Seller.  Such bank or trust company
shall have a principal office in Boston, Massachusetts or in the
Washington, D.C. metropolitan area, and shall have capital,
surplus and undivided profits in excess of $50,000,000.  If,
however, the Purchaser shall fail to name such a successor escrow
agent within fifteen (15) Business Days after the notice of
resignation from the Escrow Agent, the Seller shall be entitled to
name such successor escrow agent.  If no successor escrow agent is
named by the Purchaser or the Seller, the Escrow Agent may apply
to a court of competent jurisdiction for appointment of a
successor escrow agent.  The provisions of Sections 8.6 and 8.8
shall survive the termination of this Escrow.

          8.12 The Escrow Agent shall not be under any obligation
to take any legal action in connection with this Escrow or for its
enforcement, or to appear in, prosecute, or defend any action or
legal proceeding which, in its opinion, would or might involve it
in any costs, expense, loss, or liability, unless and as often as
required by it, it is furnished with satisfactory security and
indemnity against all such costs, expenses, losses, or
liabilities.

          8.13 Each of the Seller and the Shareholder agree to pay
the Escrow Agent's reasonable compensation for its normal services
hereunder in accordance with the attached fee schedule, which may
be subject to change on an annual basis.  The Escrow Agent shall
be entitled to reimbursement on demand for all expenses incurred
in connection with the administration of the escrow created hereby
which are in excess of its compensation for normal services
hereunder, including without limitation, payment of any legal fees
incurred by the Escrow Agent in connection with resolution of any
claim by any party hereunder.

          8.14 Notwithstanding any contrary provision contained
herein, the Escrow Agent, at all times, shall have full right and
authority to pay over and disburse the Escrow Fund in accordance
with the joint written instructions of the Purchaser, the Seller
and the Shareholder.  It is understood and agreed that should any
dispute arise with respect to the delivery, ownership, right of
possession, and/or disposition of the Escrow Fund, or should any
claim be made upon such fund by a third party, the Escrow Agent
upon receipt of written notice of such dispute or claim by the
parties hereto or by a third party, is authorized and directed to
retain in its possession without liability to anyone, all or any
of said mutual agreement of the parties involved or by a final
order, decree or judgment of a Court in the United States of
America, the time for perfection of an appeal or such order,
decree or judgment having expired.  The Escrow Agent may, but
shall be under no duty whatsoever to, institute or defend any
legal proceedings which relate to the Escrow Fund.

     9.   CONSENT TO JURISDICTION.  Each of the Purchaser, the
Seller and the Shareholder hereby absolutely and irrevocably
consent and submit to the jurisdiction of the courts of the
District of Columbia and of any Federal court located in said
jurisdiction in connection with any actions or proceedings brought
against the Purchaser, the Seller and/or the Shareholder by the
Escrow Agent arising out of or relating to this Escrow.  In any
such action or proceeding, each of the Purchaser, the Seller and
the Shareholder hereby absolutely and

 10
irrevocably waives personal service of any summons, complaint,
declaration or other process and hereby absolutely and irrevocably
agrees that the service thereof may be made by certified or
registered first-class mail directed to each of the Purchaser, the
Seller and the Shareholder, as the case may be, at their
respective addresses in accordance with Section 11 hereof.

     10.  ARBITRATION.  The parties hereto agree that any and all
disputes and claims of any nature whatsoever which relate to or
arise pursuant to this Agreement or the Purchase Agreement shall
be resolved, solely and exclusively, pursuant to arbitration in
the District of Columbia in accordance with the commercial
arbitration rules and procedures of the American Arbitration
Association in effect at the time at which the dispute or claim
arises, and judgment upon the award rendered by the arbitrator or
arbitrators may be entered in any court having jurisdiction
thereof.  If the matter in dispute concerns an amount in excess of
$300,000, there shall be three arbitrators arbitrating the matter,
with the Purchaser appointing the first arbitrator, the Seller and
the Shareholder together appointing  the second arbitrator, and
the first and second arbitrators together appointing a third
arbitrator.  The arbitrator or arbitrators shall be deemed to
possess the powers to issue mandatory orders and restraining
orders in connection with such arbitration; provided, however,
that nothing in this Section 10 shall be construed so as to deny
the Purchaser the right and power to seek and obtain injunctive
relief in a court of equity for any breach or threatened breach by
the Seller or the Shareholder of any of their covenants contained
in this Escrow.

     11.  NOTICES.  All notices, demands or requests required or
permitted hereunder shall be in writing and shall be deemed duly

shall include delivery by Express Mail, Federal Express or other
recognized overnight courier service that issues a receipt or
other confirmation of delivery) to the party for whom such
