	2.  PREMISES.

Landlord leases to Tenant and Tenant leases from Landlord that certain space
in the Building outlined in the floor plan(s) attached as Exhibit A together
with the improvements now or hereafter located in the Premises (the
"Premises"), together with the right, in common with others lawfully entitled
to use the Common Areas upon and subject to the provisions contained in this
Lease.  "Common Areas" shall mean the exterior areas serving the Building
shown in the site plan attached as Exhibit A-1 intended for the common use of
tenants and occupants of the Building, including, without limitation, parking
areas, driveways, landscaping, sidewalks, hallways, stairways, elevators,
common entrances, lobbies, restrooms and other similar public areas and
access ways.  Tenant shall have a non-exclusive right to use the parking
spaces appurtenant to the Building.  Landlord and Tenant agree that, for
purposes of this Lease, the Premises shall be deemed to have the Premises
Rentable Area equal to the square footage specified in the Basic Lease
Information.  The Premises are located at the Building Address shown in the
Basic Lease Information.
	3.  TERM.
The Premises are leased for a term (the "Term") to commence and end on the
dates respectively specified in the Basic Lease Information, unless the Term
shall sooner terminate as provided below. The dates upon which the Term shall
commence and terminate pursuant to this Section 3 are called the
"Commencement Date" and the "Expiration Date," respectively.
	4.  POSSESSION; TENANT'S WORK.

		(a)	If Landlord, for any reason whatsoever, cannot deliver
possession of the Premises to Tenant on the Commencement Date, this Lease
shall not be void or voidable, nor shall Landlord be liable to Tenant for any
loss or damage resulting from the Landlord's failure to deliver the Premises
on the Commencement Date, but in that event Rent (as defined below) shall be
waived for the period between the Commencement Date and the date Landlord
delivers possession of the Premises to Tenant.  If such delay, however, is
due primarily to the fault of Tenant or anyone acting under Tenant, there
shall be no waiver of Rent.  No delay in delivery of possession shall operate
to extend the Expiration Date beyond the date specified in the Basic Lease
Information.  Landlord and Tenant acknowledge and agree that the Premises
shall be delivered to Tenant subject to the Sublease described in Section
13(d) below.

		(b)	The Premises shall be delivered to and accepted by Tenant
"as is," in their then state of construction, finish and decoration, without
any additional obligation on the part of Landlord to prepare or construct the
Premises for Tenant's occupancy. Tenant acknowledges that (i) substantial
work must be performed by Tenant before the Premises can be occupied by
Tenant for the conduct of its business, and (ii) during the first year of the
Term of this Lease, Tenant will make certain capital improvements to the
Premises which shall include but not be limited to the following matters,
some of which are more fully described on Exhibit I attached hereto:  (1)
upgrading of the Building's electrical system(s), (2) replacement of the
Building's HVAC system, (3) replacement of the roof of the Building, (4)
removal of the asbestos in the Building identified in the Phase I
Environmental Site Assessment dated March, 2000 prepared by GZA
GeoEnvironmental, Inc. ("GZA") (File No. 16225.00) in accordance with an
"Operation and Maintenance Program for Asbestos" to be prepared by GZA within
ten (10) Business Days of the date hereof, and (5) making of certain "general
office improvements" (which shall include, but not be limited to new carpet
installation, ceiling upgrades, new or upgraded dry walls and, if necessary,
glass and window replacement) (items (i) and (ii) shall be collectively
referred to herein as the "Tenant's Work").  All of such Tenant's Work shall
be performed by Tenant at its sole risk, cost and expense in accordance with
the provisions of the Tenant Improvement Workletter attached hereto as
Exhibit B, including Tenant's obligation to obtain a new Certificate of
Occupancy for the Building allowing occupancy and use of the Premises in
accordance with the Permitted Use.  The Tenant's Work and Tenant's Work
Completion Criteria (as defined below in Section 4(e)(B)) shall be completed
and satisfied, respectively, no later than that date which is one (1) year
after the Commencement Date (the "Tenant's Work Completion Date").  Landlord
shall cooperate with Tenant in its application for any Certificate of
Occupancy including prompt execution of any necessary applications therefor
or filings in connection therewith requested reasonably by Tenant.
Notwithstanding the foregoing, Section 10 of this Lease and the provisions of
this Lease setting forth Tenant's insurance obligations (i.e., Section 16)
shall not apply during the performance of Tenant's Work and such matters
shall, during such time, be governed by the applicable provisions of Exhibit
B and Exhibit B-1A hereto.

		(c)	Landlord shall have the right to change Landlord's
Construction Representative at any time by giving written notice thereof to
Tenant.

		(d)	Subject to the provisions of Exhibit B, commencing on the
date hereof, Landlord shall permit Tenant to enter the Premises for the
purpose of performing Tenant's Work.  Any such entry shall be at Tenant's
sole risk and Landlord shall not be responsible for any damage or loss to
property or installations placed in the Premises by Tenant prior to the
Commencement Date other than those caused by the willful intent or negligence
of Landlord and its agents or advisers.  In addition, in no event shall
Tenant make use of any labor in the Building or otherwise suffer or permit
any action to be taken which would result in labor difficulties or otherwise
harm or inconvenience Landlord.  Prior to performing any of Tenant's Work,
Tenant shall provide Landlord with proof of insurance in accordance with
Exhibit B and Exhibit B-1A hereto.

		(e)	The provisions set forth below in this Section 4(e) shall
govern the security to be provided by Tenant to Landlord in connection with
the performance and Landlord's approval of the Tenant's Work.

	A.	First Floor Tenant's Work Security Amount.  As security for the
completion of the that portion of the Tenant's Work relating to the first
floor of the Premises (which work is described on Exhibit I hereto and
hereinafter referred to as the "First Floor Tenant's Work") in accordance
with the terms of this Lease, on the Commencement Date Tenant shall pay to
Landlord in immediately available United States funds the sum of Two Million
Five Hundred Thousand Dollars ($2,500,000) (the "First Floor Tenant's Work
Security Amount").  The First Floor Tenant's Work Security Amount shall be
held by Landlord in escrow in an interest bearing account in accordance with
the terms of this Section 4.  No trust relationship shall be created with
respect to the First Floor Tenant's Work Security Amount.  The First Floor
Tenant's Work Security Amount shall secure Tenant's obligations hereunder to
fully and faithfully perform all of its obligations hereunder in respect of
the First Floor Tenant's Work.  In the event that Tenant defaults in the
performance of any of its obligations hereunder relating to the First Floor
Tenant's Work and said default has not been cured within fifteen (15)
business days of Tenant's receipt of written notice of same from Landlord (or
if it shall not be reasonably possible to cure said default with fifteen (15)
business days, within such reasonable period of time as may be required to
cure said default, provided that Tenant diligently and expeditiously takes
whatever actions may be necessary to effect said cure), Landlord may, but
shall not be required to, draw on the First Floor Tenant's Work Security
Amount (or any portion thereof).  Landlord may use the monies realized from
said draw to cure Tenant's default and to compensate Landlord for any loss or
damage which Landlord may suffer as a result thereof.  If any portion of the
First Floor Tenant's Work Security Amount shall be so drawn or used, Tenant
shall within five (5) business days of a written demand therefor from
Landlord, pay to Landlord in immediately available United States funds that
amount which is necessary to replenish the First Floor Tenant's Work Security
Amount to the level of Two Million Five Hundred Thousand Dollars ($2,500,000)
and said replenishment payment shall be held by Landlord in the same manner
as the original funds constituting the First Floor Tenant's Work Security
Amount.  Landlord shall have the right to assign or pledge the First Floor
Tenant's Work Security Amount to any lender it may have during the term of
this Lease.

	B.	Return of First Floor Tenant's Work Security Amount.  Landlord
and Tenant agree that Tenant shall be entitled to the return of the First
Floor Tenant's Work Security Amount on substantial completion of the First
Floor Tenant's Work and on satisfaction of the conditions set forth in this
Section 4(e)(B).  Specifically, Landlord shall within fifteen (15) business
days of the satisfaction of the conditions set forth below return to Tenant
all of the First Floor Tenant's Work Security Amount then held by Landlord
(provided that for purposes of the return of the First Floor Tenant's Work
Security Amount said conditions shall be interpreted to apply only to the
First Floor Tenant's Work and not to the Tenant's Work on the second floor of
the Building):  (i) Landlord shall have received a written request from
Tenant for the return of the First Floor Tenant's Work Security Amount (a
"Request for Release") in the form attached to the Tenant Improvement
Agreement as Schedule 1, provided that any Request for Release submitted to
Landlord by Tenant shall have attached thereto by Tenant those items listed
at Section 6(d) of the Tenant Improvement Agreement attached hereto as
Exhibit G (which items shall be prepared or procured by Tenant and addressed
to Landlord's lender such that Landlord shall have no obligation for the
preparation or procurement thereof other than an obligation to cooperate
reasonably with Tenant in its preparation and procurement thereof); (ii)
Tenant shall have completely complied with all of its obligations hereunder
relating to the good and workmanlike completion of the Tenant's Work; (iii)
Tenant shall have provided Landlord with a Certificate of Occupancy for the
Tenant's Work and such other approvals, permits, licenses and certifications
as may be necessary for the Tenant to occupy the Premises for the Permitted
Use (provided that Tenant shall not be required to obtain a Certificate of
Occupancy in connection with its Request for Release of the First Floor
Tenant's Security Work Amount in the event that the City of Waltham refuses
to issue a partial Certificate of Occupancy for the First Floor Tenant's Work
prior to completion of all of the Tenant's Work); (iv) Tenant shall have
delivered bona fide copies of invoices and receipts for the out of pocket
costs paid by Tenant to arm's length third parties to complete the Tenant's
Work in accordance with this Lease, which receipts shall total an amount
equal to or greater than the First Floor Tenant's Work Security Amount, and
Tenant shall have provided Landlord with a certificate signed by Tenant
confirming same; and (v) Tenant shall not be in default under this Lease, the
Tenant Improvement Agreement or the Security Deposit Agreement nor shall
there be any act, event or condition that with the giving of notice or the
passage of time, or both, would constitute a breach or default under any of
said three agreements (the above items (i) - (v), inclusive, are herein
collectively referred to as the "Tenant's Work Completion Criteria").  Any
amounts due to Landlord's lender pursuant to Section 6(e)(ii) of the Tenant
Improvement Agreement shall be the sole responsibility of Tenant (which
amounts shall be deemed to be Additional Charges hereunder, the non-payment
of which shall constitute an Event of Default by Tenant hereunder).  No
partial releases of the First Floor Tenant's Work Security Amount by Landlord
to Tenant shall be permitted hereunder.

	C.	Completion of Tenant's Work; Liquidated Damages.  Tenant shall
complete the Tenant's Work and satisfy all of the Tenant's Work Completion
Criteria by no later than the Tenant's Work Completion Date.  In the event
that the Tenant's Work has not been fully completed and the Tenant's Work
Completion Criteria have not been fully satisfied by the Tenant's Work
Completion Date Landlord shall have the right, but shall not be obligated, to
claim and pay to itself the entire amount of the First Floor Tenant's Work
Security Amount then held in escrow by Landlord as liquidated damages (the
"Liquidated Damages Amount"), and not as a penalty, for those losses and
damages which Landlord has suffered as a result thereof.  Landlord and Tenant
agree that the completion of the Tenant's Work and satisfaction of the
Tenant's Work Completion Criteria by the Tenant's Work Completion Date is of
critical importance to Landlord and its business and that a breach of
Tenant's obligations to timely complete and satisfy same would cause Landlord
significant losses and damages which would be extremely difficult, if not
impossible, to ascertain with any accuracy and that the Liquidated Damages
Amount represents both parties' best efforts to approximate such potential
damages and losses.  In the event of a transfer of Landlord's interest in
this Lease, Landlord may transfer the First Floor Tenant's Work Security
Amount to Landlord's successor in interest and, upon such transfer, Landlord
shall be relieved of any and all liability for or obligation with respect to
the First Floor Tenant's Work Security Amount.  Landlord and Tenant further
agree that Landlord's lender has rights to claim the First Floor Tenant's
Work Security Amount as liquidated damages pursuant to Section 6(f) of the
Tenant Improvement Agreement in the event that a Loan Default and a Lease
Default (as each term is defined therein) occur within thirty (30) days of
one another.

	D.	Tenant Improvement Agreement.  The First Floor Tenant's Work
Security Amount shall also be governed by the terms of that certain Tenant
Improvement Agreement (the "Tenant Improvement Agreement") attached hereto as
Exhibit G.  The Tenant Improvement Agreement shall be executed by Landlord
and Tenant on or before the Commencement Date.  Tenant agrees that in the
event of any inconsistency between this Lease and the Tenant Improvement
Agreement the terms of this Lease shall prevail.

		(f)	Landlord reserves the right, at any time and from time to
time, to make alterations or additions to the Building and/or the Common
Areas, and Landlord also reserves the right at any time and from time to time
to construct other improvements in the Building (including within the Common
Areas) and to reduce or enlarge, make alterations in or make additions to the
Building and/or the Common Areas, provided that such alterations or additions
shall not unreasonably interfere with Tenant's Permitted Use hereunder.
	5.  RENT.

		(a)	Beginning on the Commencement Date, Tenant shall pay to
Landlord as annual minimum rent for the Premises the sum specified in the
Basic Lease Information as "Base Rent".   Base Rent shall be payable in equal
monthly installments on or before the first day of the Term and on or before
the fifteenth day of each and every calendar month thereafter during the
Term.  In the event the Term commences or ends on a day other than the first
or last day, respectively, of a calendar month, then the monthly Base Rent
for such fractional month shall be prorated on a daily basis based upon a
thirty (30) day calendar month.  Base Rent shall be paid to Landlord, without
any prior demand and without any deduction or offset whatsoever, in lawful
money of the United States of America at the address for payment of rent
specified in the Basic Lease Information, or to such other person or at such
other place as Landlord may from time to time designate by notice to Tenant.

		(b)	Tenant shall pay to Landlord as additional charges all
fees, costs, expenses, charges, and other amounts required to be paid by
Tenant under this Lease other than Base Rent ("Additional Charges").
Additional Charges shall be payable to Landlord at the place where the Base
Rent is payable.  Landlord shall have the same remedies for a default in the
payment of Additional Charges as for a default in the payment of Base Rent.
The terms 'Base Rent' and 'Additional Charges' are sometimes collectively
referred to herein as "Rent".

		(c)	If Tenant shall fail to pay to Landlord any installment of
Rent on or before the date such installment is due and payable more than one
(1) time in any twelve (12) consecutive month period, then Tenant shall pay
to Landlord in each instance a late payment charge equal to five percent (5%)
of the unpaid amount of such Rent to cover Landlord's additional
administrative costs resulting from Tenant's failure.  Additionally, without
limiting any of Landlord's other rights and remedies under this Lease, if any
payment of Rent or any other payment payable under this Lease by Tenant to
Landlord shall not be paid when due, such Rent or other payment shall bear
interest from the date when the Rent or other payment, as may be the case,
was payable until the date paid at (a) the prime rate as announced by Fleet
National Bank at its main branch in Boston, Massachusetts from time to time
plus two percent (2%), but not more than (b) the highest lawful rate of
interest which Landlord may charge Tenant without violating any applicable
law.  Such interest shall constitute an Additional Charge hereunder.

		(d)	Tenant agrees that acceptance by Landlord of any partial
payment of any item of rental due under this Lease (whether denominated as
Base Rent, Additional Charges or otherwise) shall not constitute an accord
and satisfaction by Landlord of any of Tenant's obligations under this Lease,
and that Landlord shall be entitled to collect from Tenant the balance of any
such item of Rent remaining due.

		(e)	Tenant agrees that this Lease is a net lease and the Base
Rent, Additional Charges, Taxes, Expenses and all other sums payable under this
Lease to Landlord shall be paid without notice or demand, and without setoff,
abatement, suspension, deferment, reduction or deduction, except as otherwise
expressly provided herein.
	6.  SECURITY DEPOSIT.
  The provisions set forth below in this Section 6 shall govern the Security
Deposit to be held by Landlord pursuant to the terms of this Lease.

	(a)	Security Deposit Letter of Credit.  Simultaneously with its
execution and delivery of this Lease, Tenant shall deposit with Landlord the
sum specified in the Basic Lease Information as the "Security Deposit" in the
form of the Security Deposit Letter of Credit. The Security Deposit Letter of
Credit shall (i) name Landlord as beneficiary thereof, (ii) have a term of
not less than one (1) year, (iii) be in the original amount equal to the
Security Deposit, and (iv) otherwise be in form and content satisfactory to
Landlord.  The Security Deposit Letter of Credit shall, in any event, provide
that:

		(1)	The Issuing Bank shall pay to Landlord an amount up to the
face amount of the Security Deposit Letter of Credit upon presentation
of only a demand for payment in the amount to be drawn;

		(2)	The Security Deposit Letter of Credit shall be deemed to be
automatically renewed, without amendment, for consecutive periods of
one year each and shall have a final expiry date of not earlier than
thirty (30) days after the Expiration Date, as such may be extended as
provided herein, unless the Issuing Bank sends written notice
(hereinafter called the "Non-Renewal Notice") to Landlord both by
Federal Express or another recognized national or regional courier and
by certified or registered mail, return receipt requested, not less
than sixty (60) days next preceding the then expiration date of the
Security Deposit Letter of Credit, that it elects not to have such
Security Deposit Letter of Credit renewed;

		(3)	Landlord, after receipt of the Non-Renewal Notice, or
within sixty (60) days prior to the expiration date of any Security
Deposit Letter of Credit then held by Landlord, shall have the right,
exercisable by a demand for payment draft only to draw upon the
Security Deposit Letter of Credit and receive the proceeds thereof
(which shall be held by Landlord as a cash deposit pursuant to the
terms of this Section 6 pending the replacement of such Security
Deposit Letter of Credit or applied as permitted by the terms of this
Section 6); and

		(4)	Upon Landlord's sale or other transfer of the Land or the
Building, or Landlord's interest therein, or a leasing of the Building,
the Security Deposit Letter of Credit shall be transferable by Landlord
and Landlord shall thereupon be released by Tenant from all liability
for the return of such Security Deposit Letter of Credit.  In such
event, Tenant agrees to look solely to the new Landlord for the return
of said Security Deposit Letter of Credit.  Tenant shall execute such
documents as may be necessary to accomplish such transfer or assignment
of the Security Deposit Letter of Credit and shall pay any transfer
fees of the Issuing Bank.

	Tenant covenants that it will not assign or encumber, or attempt to
assign or encumber, the Security Deposit Letter of Credit or proceeds
thereof, and that neither Landlord nor its successors or assigns shall be
bound by any such assignment, encumbrance, attempted assignment, or attempted
encumbrance.  If Landlord determines that the financial condition of the
Issuing Bank has so declined as to cause concern that the Issuing Bank may
not honor a draw on its Security Deposit Letter of Credit and provides Tenant
of notice of the same, Tenant shall promptly obtain a replacement Security
Deposit Letter of Credit complying with the terms hereof from another
commercial bank acceptable to Landlord.

	(b)	Draws and Transfer of Security Deposit Letter of Credit.  The
Security Deposit shall be held by Landlord as security for the full and
faithful performance by Tenant of all the provisions of this Lease.  If
Tenant defaults with respect to any provision of this Lease, including,
without limitation, provisions relating to the payment of Rent, Landlord may,
but shall not be required to, draw on the Security Deposit Letter of Credit
and use, apply or retain all or any part of the Security Deposit for the
payment of any Rent or to compensate Landlord for any other loss or damage
which Landlord may suffer by reason of Tenant's default.  If any portion of
the Security Deposit is so used, applied or retained, Tenant shall within
five (5) days after demand from Landlord, provide Landlord with a replacement
letter of credit in the amount and on the terms specified in the Basic Lease
Information provisions relating to the Security Deposit Letter of Credit.  No
trust relationship shall be created with respect to the Security Deposit and
Tenant shall not be entitled to interest on the Security Deposit.  If Tenant
shall fully and faithfully perform every provision of this Lease and this
Lease shall expire or be terminated, the Security Deposit Letter of Credit
shall be promptly returned to Tenant by Landlord in its then current
condition.  In the event of termination of Landlord's interest in this Lease,
Landlord may transfer the Security Deposit to Landlord's successor in
interest and, upon such transfer, Landlord shall be relieved of any and all
liability for or obligation with respect to the Security Deposit.  Landlord
shall also have the right to assign or pledge the Security Deposit Letter of
Credit to any lender it may have during the Term of this Lease.

	(c)	Security Deposit Agreement.  The Security Deposit shall be
governed by the terms of that certain Agreement Concerning Disposition of
Security Deposit (the "Security Deposit Agreement") attached hereto as
Exhibit H.  The Security Deposit Agreement shall be executed and delivered by
Landlord and Tenant on or before the Commencement Date.  Tenant agrees that
in the event of any inconsistency between this Lease and the Security Deposit
Agreement the terms of this Lease shall prevail.
	7.  TENANT'S SHARE OF COSTS.

		(a)	During the Term, Tenant shall pay to Landlord as Additional
Charges: (i) Tenant's Share of all Taxes and Expenses (each as defined
below).

		(b)	During the last month of each Expense Computation Year and
each Tax Computation Year (each as defined below), as the case may be, or as
soon thereafter as practicable, Landlord shall give to Tenant notice of
Landlord's estimate of the amounts payable by Tenant under Section 7(a) for
the following Expense Computation Year or Tax Computation Year, as the case
may be.  On or before the first day of each month during the following
Expense Computation or Tax Computation Year, as the case may be, Tenant shall
pay to Landlord one-twelfth (1/12th) of such estimated amounts; provided,
however, that if Landlord fails to give such notice in the last month of the
prior Expense Computation Year or Tax Computation Year, as the case may be,
then Tenant shall continue to pay on the basis of the prior year's estimate
until the first day of the calendar month next succeeding the date such
notice is given by Landlord.  If at any time or times Landlord determines
that the amounts payable under Section 7(a) for the current Expense or Tax
Computation Year, or both, will vary from its estimate given to Tenant,
Landlord, by notice to Tenant, may revise its estimate for such Expense or
Tax Computation Year, or both, and subsequent payments by Tenant for such
Expense or Tax Computation Year, or both, shall be based upon such revised
estimate.

		(c)	Following the end of each Expense Computation Year or Tax
Computation Year, Landlord shall deliver to Tenant a statement of amounts
payable under Section 7(a) for such Expense Computation Year and Tax
Computation Year.  If such statement shows an amount owing by Tenant that is
less than the payments for such Expense Computation Year or Tax Computation
Year, or both, previously made by Tenant, and if no Event of Default (as
defined below) is outstanding at the time such statement is delivered,
Landlord shall credit such amount to the next payments of Rent falling due
under this Lease.  If such statement shows an amount owing by Tenant that is
more than the estimated payments for such Expense Computation Year or Tax
Computation Year, or both, previously made by Tenant, Tenant shall pay the
deficiency to Landlord within thirty (30) days after delivery of such
statement.  The respective obligations of Landlord and Tenant under this
Section 7(c) shall survive the Expiration Date, and, if the Expiration Date
is a day other than the last day of an Expense or Tax Computation Year, or
both, the adjustment in Rent pursuant to this Section 7 for the Expense
Computation Year or Tax Computation Year, or both, in which the Expiration
Date occurs shall be prorated in the proportion that the number of days in
such Expense Computation Year and/or Tax Computation Year preceding the
Expiration Date bears to 365.

		(d)	As used in this Lease, the following terms shall have the
meanings specified below:

			(i)	"Expenses" shall mean (1) all costs of management (if
applicable, said costs shall not exceed two percent (2%) of the net operating
income of the Building), operation, maintenance and repair of the Land,
Building and Common Areas, and the improvements situated thereon, including,
without limitation, janitorial, maintenance, maintenance and repair of the
roof of the Building and parking and landscaped areas on the Land, security

reasonably charged by Landlord if Landlord performs any such services in
connection with the Building; and (2) the cost of any capital improvements
made to the Building after its construction that reduce other Expenses or
made to the Building after the date of this Lease as a result of governmental
orders, ordinances, codes, rules and regulations that were inapplicable to
the Building at the time permits for its construction were obtained, such
cost to be amortized over the useful life of such capital improvement as
determined in accordance with generally accepted accounting procedures,
together with interest on the unamortized balance at a rate equal to ten
percent (10%) per annum or such higher rate as may have been paid by Landlord
on funds borrowed for the purpose of constructing such improvements.
Notwithstanding the foregoing, Expenses shall not include Taxes, depreciation
on the Building, costs of installing capital improvements (except as provided
in clause (2) above), real estate brokers' commissions, executive salaries
(exclusive of salaries, wages or fees paid for management activities), tenant

Tenant.

			(ii)	"Taxes" shall mean all taxes, assessments and charges
levied upon or with respect to the Building, any personal property of
Landlord used in the operation of the Building or Landlord's interest in the
Building or such personal property.  Taxes shall include, without limitation,
all general real property taxes and general and special assessments, transit
charges, service payments in lieu of taxes and any tax, fee or excise on the
act of entering into this Lease or any other lease of space in the Building,

also include any other tax, fee or other excise, however described, that may
be levied or assessed as a substitute for, or as an addition to, in whole or
in part, any other Taxes, whether or not now customary or within the
contemplation of the parties.  Taxes shall not include franchise, transfer or
inheritance taxes, or income taxes measured by the net income of Landlord
from all sources, unless, due to a change in the method of taxation, any of
these taxes are levied or assessed against Landlord as a substitute for, or
as an addition to, in whole or in part, any other tax that would otherwise
constitute a Tax.  Taxes shall also include reasonable legal and tax
consultants' fees, costs and disbursements incurred in connection with
proceedings to contest, determine or reduce Taxes.

			(iii)	"Tenant's Share" shall mean the percentage figure so
specified in the Basic Lease Information, which is calculated by dividing the

(12) consecutive month period commencing January 1st of each year during the
Term.

		(a)	Tenant shall use and occupy the Premises for any purpose

use or permit the Premises to be used for any other purpose.

		(b)	Tenant shall take no action, nor permit any action to be
taken, in or about the Premises that will in any way increase the existing
rate of or affect any fire or other insurance upon the Building or any of its
contents, or cause cancellation of any insurance policy covering all or any
part of the Building or any of its contents.  Tenant shall not use or allow
the Premises to be used for any improper, immoral, unlawful or objectionable
purpose, permit pornography or apparatus for the use of illegal drugs to be
held on the Premises, or cause, maintain or permit any nuisance in, on or

any waste in, on or about the Premises.

		(c)	Tenant shall not cause or suffer or permit any Hazardous
Materials, as defined below, to be brought upon, kept, used, discharged,
deposited or leaked in or about the Premises or the Building or Common Areas
by Tenant or any of Tenant's agents or by anyone in the Premises (other than
Landlord or its agents, employees or contractors), except to the extent such
Hazardous Materials are customarily kept or used by typical office tenants
and are kept and used in accordance with all applicable Laws.  If Tenant
breaches the obligations stated in the preceding sentence, or if the presence
of any Hazardous Material on the Premises or the Building or Common Areas
caused or suffered or permitted by Tenant or any of Tenant's agents or by
anyone in the Premises (other than Landlord or its agents, employees or
contractors) results in contamination of the Premises or the Building or
Common Areas, or if contamination of the Premises or the Building by any
Hazardous Material otherwise occurs for which Tenant is legally liable, then
Tenant shall indemnify, defend and hold Landlord harmless from any and all
claims, damages, costs, liabilities and expenses (including, without
limitation, diminution in value or use of the Building, attorneys' fees,
consultant fees and expert fees) which arise during or after the Term as a
result of such contamination.  This indemnification shall include, without
limitation, costs incurred in connection with any investigation of site
conditions or any clean-up, remediation, removal or restoration work on or
under the Premises or the Building or Common Areas.  "Hazardous Materials"
means any hazardous or toxic substance, material or waste which is or becomes
regulated by any local, state or federal governmental authority or by common
law decisions, including without limitation (i) all chlorinated solvents,
(ii) petroleum products or by-products, (iii) asbestos, and (iv)
polychlorinated biphenyls.  Notwithstanding the above provisions, Tenant
shall have the right to install a "back-up" generator on or about the
Premises.  Installation of the "back-up" generator shall be performed in a
good and workmanlike manner in compliance with all applicable Laws by
licensed contractors reasonably approved by Landlord.  Landlord agrees that
Tenant shall have the right to remove and retain the "back-up" generator upon
the expiration or earlier termination of this Lease, provided Tenant repairs
and restores the Premises (in connection with the removal of the "back-up"
generator) to their condition prior to the installation of such "back-up"
generator.  Tenant agrees that it shall indemnify, defend and hold Landlord
harmless from any and all claims, damages, costs, liabilities and expenses
(including, without limitation, diminution in value or use of the Building,
reasonable attorneys' fees, consultant fees and expert fees) which arise
during or after the Term as a result of the installation, use or removal of
such "back-up" generator.
	9.  COMPLIANCE WITH LAW.
Tenant shall not use the Premises in any manner, or permit anything to be
done in or about the Premises, which will in any way conflict with any law,
statute, ordinance or governmental rule, regulation or order now in force or
hereafter enacted or promulgated (collectively, "Laws").
	10.  ALTERATIONS.
Except for Tenant's Work (for which Landlord review and approval is required
pursuant to Exhibit B) and installation of the "back-up" generator referred
to above in Section 8(c), Tenant shall not before or during the Term make or
suffer to be made any alterations, additions or improvements in or to the
Premises (herein collectively called "Alterations") without first obtaining
Landlord's written consent.  Tenant shall submit detailed plans and
specifications for the Alterations in connection with requesting Landlord's
consent.  Landlord's consent may be withheld in Landlord's sole discretion if
the Alterations will affect the structure of the Building or the Building's
systems; otherwise Landlord's consent shall not be unreasonably withheld.  As
a condition of approving the proposed Alterations, Landlord may require
Tenant to agree to remove all or any part of such Alterations on or before
the Expiration Date and to reimburse Landlord for any reasonable expenses
incurred by Landlord in reviewing the plans and specifications, including,
without limitation, the reasonable costs of any outside consultants retained
by Landlord.  All Alterations shall immediately become Landlord's property
and shall remain in the Premises at the end of the Term without compensation
to Tenant unless Landlord conditioned its approval of such Alterations on
Tenant's agreement to remove them, in which event Tenant shall by the
Expiration Date remove such Alterations and restore the Premises to their
condition prior to the installation of such Alterations.  All Alterations
shall be done in a good and workmanlike manner, in compliance with all
applicable Laws by licensed contractors approved by Landlord.  Tenant shall
also comply with the provisions of Section 11 in connection with any Tenant
Alterations it undertakes at the Premises.

	11.  REPAIRS.

		(a)	By occupying the Premises, Tenant accepts the Premises as
being in the condition in which Landlord is obligated to deliver the Premises
under the terms of this Lease.  Tenant shall, at all times during the Term,
and at Tenant's sole expense, keep all of the Premises in good condition and
repair, except for ordinary wear and tear or damage by fire or casualty.
Tenant waives all rights to make repairs at the expense of Landlord or in
lieu of such repairs to vacate the Premises as provided by any law, statute
or ordinance now or hereafter in effect.  Tenant shall at the end of the Term
surrender the Premises to Landlord in the same or improved condition as when
received, except for ordinary wear and tear, damage by fire, casualty and
Alterations approved by Landlord and not required by Landlord to be removed
by Tenant.

		(b)	Notwithstanding the provisions of Section 11(a), Landlord
shall repair and maintain the structural portions of the Building (including
load-bearing walls), unless the necessity for such maintenance and repairs is
in any way caused by the act, neglect, fault or omission of Tenant, its
agents, servants, employees or invitees, in which case Tenant shall pay to
Landlord the reasonable cost of such maintenance and repairs.  Landlord shall
not be liable for any failure to make any such repairs or to perform any such
maintenance.  Rent shall not abate nor shall Landlord be liable as a result
of any injury to or interference with Tenant's business arising from the
making of any repairs, or the performance of any maintenance, in or to any
portion of the Building or the Premises or the Common Areas.
	12.  LIENS.
Tenant shall keep the Premises and the Building free from any liens arising
out of any act or omission of Tenant, including, without limitation, any work
performed, materials furnished or obligations incurred by Tenant.  In the
event that Tenant shall not, within fifteen (15) days following notice of the
imposition of any such lien, cause same to be released of record by payment
or posting of a bond fully satisfactory to Landlord in form and substance,
Landlord shall have, in addition to all other remedies provided herein and by
law, the right (but not the obligation) to cause the lien to be released by
such means as Landlord shall deem proper, including, without limitation,
payment of the claim giving rise to such lien.  All such sums paid by
Landlord and all expenses incurred by it in connection with investigating,
releasing, bonding-off or disputing liens on the Premises or the Building
arising out of any act or omission of Tenant shall be considered Additional
Charges and shall be payable by Tenant within thirty (30) days after demand.
Landlord shall have the right to post and keep posted on the Premises any
notices that may be provided by law or that Landlord may deem to be proper
for the protection of Landlord, the Premises and the Building from such
liens.  Tenant shall give to Landlord at least ten (10) days' prior notice of
the date of commencement of any Alterations on the Premises in order to
permit the posting of such notices by Landlord.  Landlord may require, in
Landlord's sole discretion, that Tenant, at Tenant's sole expense, provide to
Landlord a lien and completion bond in form and substance satisfactory to
Landlord in an amount equal to one hundred fifty percent (150%) of the total
estimated cost of any Alterations to insure Landlord against any liability
for mechanics' and materialmen's liens and to insure completion of work.
Notice is hereby given that Landlord shall not be liable for any labor,
services or materials furnished or to be furnished to Tenant for the Premises
or to anyone holding any of the Premises through or under Tenant, and that
mechanics', construction or other liens for any such labor, services or
materials shall not attach to the Premises or otherwise affect the interest
of Landlord in and to the Premises.  Tenant agrees to notify any contractors,
subcontractors or others performing services or providing materials to the
Premises of the foregoing provision of this Lease.

	13.  ASSIGNMENT AND SUBLETTING.

		(a)	Tenant shall not (i) assign or mortgage this Lease or any
right under or interest in it, (ii) allow this Lease to be assigned by
operation of law or otherwise, (iii) sublet the Premises or any part of the
Premises, or (iv) permit anyone to use or occupy the Premises or any part of
the Premises in place of Tenant without the prior written consent of
Landlord.  Any sale or other transfer of a majority of the voting stock or
partnership interest of Tenant or any guarantor of Tenant's obligations under
this Lease shall be considered an assignment for purposes of this Section 13.
Any such assignment, mortgage or subletting without Landlord's consent shall
be void and shall, at Landlord's option, constitute a breach of this Lease.
Notwithstanding consent by Landlord of any subletting or assignment by
Tenant, Tenant, any guarantor of Tenant's obligations under this Lease and
each assignee and subtenant shall remain directly and primarily responsible
and jointly and severally liable for payment of the Rent required under this
Lease and for compliance with all of Tenant's other obligations, and no usage
of the Premises different from the usage herein provided to be made by Tenant
shall be permitted.  In the event that the rent due and payable by an
assignee or sublessee exceeds the Rent payable under this Lease, the excess
rental or consideration shall be paid by Tenant to Landlord within ten (10)
days following receipt of any excess rental or consideration by Tenant.
Consent of Landlord to any assignment, mortgage or subletting shall
constitute approval only as to that specific assignment, mortgage or
subletting, and none other.

		(b)	Any request by Tenant for Landlord's consent to a specific
assignment or sublease shall include (i) the name of the proposed assignee,
sublessee or occupant, (ii) the nature of the proposed assignee's,
sublessee's or occupant's business to be carried on in the Premises, (iii) a
copy of the proposed assignment or sublease, and (iv) such financial
information and such other information as Landlord may reasonably request
concerning the proposed assignee, sublessee or occupant or its business.
Landlord shall respond in writing, stating the reasons for any disapproval,
within fifteen (15) business days after receipt of all information reasonably
necessary to evaluate the proposed assignment or sublease.

		(c)	Tenant shall pay to Landlord the reasonable amount of
Landlord's cost of processing every proposed assignment or sublease
including, but not limited to, attorneys' fees and the reasonable amount of
all direct and indirect expenses incurred by Landlord arising from any
assignee, sublessee or occupant taking occupancy.

		(d)	Notwithstanding any other provision set forth herein,
Tenant shall be permitted to enter into a sublease (the "Sublease") of the
Premises by and between Tenant, as sublandlord, and Fleet National Bank, a
national banking association (the "Subtenant") as subtenant, for
approximately Eighteen Thousand Sixty (18,060) square feet of space on the
second floor of the Building and approximately Ten Thousand (10,000) square
feet of space on the first floor of the Building.  The Sublease shall be in
the form attached hereto as Exhibit E.  Provided that Subtenant is not in
material default of the Sublease, Landlord shall not disturb Subtenant's
quiet enjoyment of its premises under the Sublease for the entire term
thereof.

		(e)	Notwithstanding the foregoing provisions of this Section
13, an assignment, sublease or transfer of the Premises shall not require the
consent of the Landlord if such assignment, sublease or transfer is to an
Affiliate of the Tenant (as defined herein) provided such Affiliate agrees
directly with Landlord to be bound by all obligations of Tenant hereunder.
For purposes hereof, "Affiliate" means (i) any entity directly controlling,
controlled by or under common control with Tenant; (ii) any entity owning or
controlling fifty percent (50%) or more of the outstanding voting interests
of Tenant; (iii) any entity of which Tenant owns or controls fifty percent
(50%) or more of the voting interests; (iv) any entity into which Tenant is
merged or consolidated; (v) any entity into which Tenant is merged or any
corporation or other entity resulting from the consolidation of Tenant with
some other entity; and (vi) any successor corporation to Tenant or other
entity arising from any bona fide reorganization of Tenant.  No subletting,
assignment or transfer of this Lease either with or without the consent of
Landlord shall relieve the Tenant from its obligations under this Lease and
Tenant hereby guarantees the prompt and timely payment of all Base Rent and
Additional Charges and the timely performance of all other obligations of
Tenant hereunder.
	14.  INDEMNIFICATION.

		(a)	If Tenant shall default in the performance of its
obligations under this Lease, Landlord, at any time thereafter on five (5)
business days written notice, may remedy such default for Tenant's account
and at Tenant's expense.  By curing such default, Landlord does not waive any
other rights or remedies of Landlord with respect to such default.

		(b)	Tenant agrees to indemnify Landlord against and hold
Landlord harmless from any and all loss, cost, liability, damage and expense
including, without limitation, penalties, fines and reasonable attorneys'
fees, incurred in connection with or arising from any cause whatsoever in, on
or about the Premises.

		(c)	Tenant waives all claims against Landlord for damage to any
property or injury or death of any person in, upon or about the Premises or
Building or Common Areas arising at any time and from any cause other than
solely by reason of the gross negligence or willful act of Landlord or its
employees or contractors.

		(d)	Tenant's obligations under this Section 14 shall survive
the expiration or sooner termination of the Term.

		(e)	All fixtures, equipment, signs, merchandise, supplies and
other property on or about the Premises shall be at Tenant's sole risk and
hazard, and if the whole or any part thereof shall be destroyed or damaged by
fire, water or otherwise, or by use or abuse of water, or by leaking or
bursting of water pipes, or in any way or manner, including, without
limitation, the acts or omissions of any other occupant of any portion of the
Building, no part of said destruction or damage is to be charged to or borne
by Landlord in any case whatsoever, except only to the extent caused by
Landlord's gross negligence or willful default and, except to such extent,
Tenant agrees to exonerate Landlord from and against any and all claims,
suits, obligations, liabilities and damages, including reasonable attorneys'
fees, based upon or arising out of any of the foregoing.
	15.  SUBROGATION.
Landlord and Tenant each shall obtain from their respective insurers under all
policies of fire and extended coverage insurance maintained by either at any
time during the Term insuring or covering the Building or Premises or any
improvements, fixtures, equipment, furnishings or other property, including
salable goods, merchandise, and inventory in, on or about the Premises, if any,
a waiver of all rights of subrogation which such party or the insurer of such
party might have against the other party or its insurer.

Tenant agrees to carry and keep in force during the Term, at Tenant's sole
expense, the following types of insurance:

		(i)	Public Liability and Property Damage.  Commercial general
liability insurance including contractual liability with a minimum combined

		(ii)	Tenant's Property.  Insurance covering any and all
fixtures, equipment, furnishings and personal property of Tenant from time to
time in, on or about the Premises, providing protection against all perils
included within a standard fire and extended coverage "all risk form"

the leases in the Building (whether or not such leases are terminable in the
event of a fire or casualty), such rental loss insurance to cover rental
losses for a period of at least one (1) year after the date of the fire or
casualty in question.  The amount of such rental loss insurance shall be
increased from time to time during the term of this Lease as and when new

increased additional rent payable by all of the tenants under such renewal
leases and all rent and additional rent payable by all of the tenants under
such new leases;

insurance companies with a general policyholders' rating of not less than A
and a financial rating of XIII as rated in the most current available "Best's
Insurance Reports," and qualified to do business in the Commonwealth of
Massachusetts; and, except for workers' compensation and employers'
liability, all such policies shall include Landlord and Landlord's lender as
additional insureds.  All such policies of insurance shall be procured for
periods of not less than one (1) year.  Executed copies or certificates of
all such policies of insurance shall be delivered to Landlord within ten (10)
days before delivery of possession of the Premises to Tenant, and thereafter
within thirty (30) days prior to the expiration of the term of each such
policy.  All commercial general liability insurance policies shall contain a
provision that Landlord, although included as an additional insured, shall
nevertheless be entitled to recovery under such policies for any loss
occasioned to Landlord, its agents and employees by reason of the negligence
or willful act of Tenant.  As often as any such policy shall expire or
terminate, renewal or additional policies shall be procured and maintained by
Tenant in like manner and to like extent.  All such policies of insurance
shall provide that the company writing such policy shall give to Landlord
thirty (30) days' prior written notice of any cancellation or lapse or the
effective date of any reduction in the amounts of insurance.  Notwithstanding
the foregoing, if any such insurance expires without having been renewed by
Tenant, Landlord shall have the option in addition to Landlord's other
remedies to procure such insurance for the account of Tenant immediately and
without notice to Tenant, and the cost of such insurance shall be paid to
Landlord an Additional Charge.  The limits of the insurance required under
this Lease shall not limit the liability of Tenant.  All public liability,
property damage and other casualty policies shall be written as primary
policies, not contributing with and not in excess of, any coverage which
Landlord may carry.
	17.  SERVICES AND UTILITIES.

		(a)	Tenant shall make all arrangements for and pay before
delinquent all charges for all utilities and services furnished to or used by
it in connection with the Premises, including, without limitation, gas,
electricity, water, telephone service, and trash collection, and for all
connection charges.  Landlord shall not be liable for, and Tenant shall not
be entitled to, any reduction of Rent by reason or on account of (i) the
installation, use of or interruption of use of any equipment in connection
with the furnishing of any of the foregoing services, (ii) the failure to
furnish or delay in furnishing any of the foregoing services when such
failure is caused by accident, breakage, repairs, strikes, lockouts or other
labor disturbances or labor disputes of any character, or by any other cause,
similar or dissimilar, or by the making of any repairs or improvements to the
Premises or to the Building or any portion of either, or (iii) the
limitation, curtailment, rationing or restriction on use of water,
electricity, gas or any other utility serving the Premises or the Building by
any utility or governmental agency.

		(b)	The cost of any such meters and of their installation,
maintenance and repair shall be paid for by Tenant, and Tenant agrees to pay
to Landlord as Additional Charges promptly upon demand all charges for such
water and electric current consumed as shown by such meters, at the rates
charged for such services by the local public utility furnishing the same,
plus any additional expense incurred in providing and keeping account of the
water and electric current so consumed.  If a separate meter is not
installed, such excess cost for such water and electric current shall be
established by an estimate made by a utility company or an engineer selected
by Landlord and shall be paid to Landlord as Additional Charges.
	18.  TAXES ON TENANT'S PERSONAL PROPERTY.
 Tenant agrees to pay, before delinquency, any and all taxes levied or
assessed during the Term upon Tenant's equipment, furniture, fixtures, and
other personal property located in, on or about the Premises or Building.  In
the event any or all of Tenant's equipment, furniture, fixtures and other
personal property shall be assessed and taxed with the Building, Tenant shall
pay to Landlord as Additional Charges the taxes so levied with respect to
such personal property within ten (10) days after delivery to Tenant by
Landlord of a statement setting forth the amount of such taxes applicable to
Tenant's property.
	19.  RULES AND REGULATIONS.
Tenant shall faithfully observe and comply with the rules and regulations
with respect to the Building and Common Areas that are attached as Exhibit C.
Landlord reserves the right from time to time to make reasonable additions
and modifications to such rules and regulations.  Any such additions and
modifications shall be binding upon Tenant upon delivery of a copy of them to
Tenant.
	20.  HOLDING OVER.
Any holding over by Tenant after the Expiration Date with the prior consent
of Landlord shall be construed to be a tenancy from month to month on all of
the terms, covenants, and conditions herein specified but at a monthly Base
Rent equal to twice the monthly Base Rent in effect immediately prior to the
Expiration Date, provided that Tenant shall not be liable for consequential
damages in connection with holding over pursuant to the provisions of this
Section 20.  Acceptance by Landlord of Rent after the Expiration Date without
Landlord's prior consent shall not constitute a consent by Landlord to any
such tenancy from month to month or result in any other tenancy or any
renewal of the Term.  The provisions of this Section 20 are in addition to,
and do not affect, Landlord's right of re-entry or other rights under this
Lease or provided by law.
	21.  ENTRY BY LANDLORD.
  Landlord, its agents, and employees shall have access to and the right to
enter upon the Premises at any reasonable time upon reasonable advance notice
to Tenant, to examine the condition of the Premises, to make any repairs or
alterations required to be made by Landlord under this Lease, to show the
Premises to prospective purchasers, lenders, or tenants, and for any other
purpose deemed reasonable by Landlord, without liability for trespass.  In
any circumstances where Landlord is permitted to enter upon the Premises
during the Term, no such entry shall constitute an eviction or disturbance of
Tenant's use and possession of the Premises or a breach by Landlord of any of
its obligations under this Lease or render Landlord liable for damages for
loss of business or otherwise entitle Tenant to be relieved from any of its
obligations under this Lease or grant Tenant any right of setoff or
recoupment remedy.
	22.  DAMAGE AND DESTRUCTION.
  If the Premises or the Building is damaged by fire or other casualty,
Landlord shall promptly repair such damage to the extent of the insurance
proceeds (after deduction of Landlord's costs of adjustment and collection)
available for restoration of the Premises or the Building, as the case may
be, subject to the provisions of this Section 22, if, in Landlord's judgment,
such repairs can be made within one hundred twenty (120) days.  During the
making of such repairs by Landlord, this Lease shall remain in full force and
effect, except that if the damage is not the result of any act, neglect,
default or omission of Tenant, its agents, employees or invitees, Tenant
shall be entitled to a reduction of Rent while such repair is being made in
the proportion that the Premises Rentable Area rendered untenantable by such
damage bears to the total Premises Rentable Area.   In the event (i) the
uninsured portion of any damage to or destruction of the Building equals or
exceeds ten percent (10%) of the replacement cost of the Building; or (ii)
the Term will expire within one (1) year from the date of any material damage
to or destruction of the Premises; or (iii) the damage cannot, in Landlord's
reasonable opinion, be repaired within one hundred twenty (120) days,
Landlord shall have the option either (a) to repair such damage, this Lease
continuing in full force and effect but with the Rent proportionately reduced
upon the conditions and as provided above, or (b) at any time within
thirty (30) days after the occurrence of such damage, to give notice to
Tenant terminating this Lease as of a date specified in such notice, which
date shall not be less than thirty (30) nor more than sixty (60) days after
the giving of such notice.  If Landlord elects to terminate this Lease by
giving such notice of termination to Tenant, this Lease and all interest of
Tenant in the Premises shall terminate on the date specified in such notice,
and the Rent, proportionately reduced as provided above, shall be paid up to
the date of such termination, with Landlord refunding to Tenant any Rent
previously paid for any period of time subsequent to such date.  If Landlord
elects or is required to repair the Premises or the Building under this
Section 22, Landlord shall repair at its cost any injury or damage to the
Building and the leasehold improvements in the Premises, and Tenant shall be
responsible for and shall repair at its sole cost all fixtures, equipment,
furniture or any other property of Tenant in the Premises.  Tenant shall not
be entitled to any compensation or damages from Landlord for damage to any of
Tenant's fixtures, personal property or equipment, for loss of use of all or
any part of the Premises, for any damage to Tenant's business or profits, or
for any disturbance to Tenant caused by any casualty or the restoration of
the Premises following such casualty.
	23.  DEFAULT.
The occurrence of any one or more of the following events shall constitute a
default and breach of this Lease by Tenant (collectively, an "Event of
Default"):

		(a)	The failure of Tenant to pay any installment of Rent on or
before the date such installment is due and such delinquency or failure to pay
shall continue for ten (10) days after written notice from Landlord.

		(b)	The failure by Tenant to observe or perform any of the
provisions of this Lease to be observed or performed by Tenant, other than as
described in Section 23(a), where such failure shall continue for a period of
fifteen (15) days after notice of such failure by Landlord to Tenant;
provided, however, that if the nature of Tenant's default is such that more
than fifteen (15) days are reasonably required for its cure, then Tenant
shall not be deemed to be in default if Tenant commences such cure within
such fifteen (15) day period and thereafter diligently prosecutes such cure
to completion.

		(c)	The making by Tenant of any general assignment or general
arrangement for the benefit of creditors; or the filing of any action by or
against Tenant under any insolvency, bankruptcy, reorganization, moratorium,
or other debtor relief statute, whether now or hereafter existing, (unless in
the case of such action taken against Tenant, the same is dismissed within
sixty (60) days); or the appointment of a trustee or a receiver to take
possession of substantially all of Tenant's assets located at the Premises or
of Tenant's interest in this Lease, where possession is not restored to
Tenant within thirty (30) days; or the attachment, execution or other
judicial seizure of substantially all of Tenant's assets located at the
Premises or of Tenant's interest in this Lease, where such seizure is not
discharged in ten (10) days; or the admission by Tenant in writing of the
inability to pay its debts as they become due.

		(d)	If this Lease or all or any part of the estate or interest
of Tenant under this Lease or created by this Lease shall be assigned,
subleased, mortgaged, encumbered or otherwise disposed of without compliance
with the provisions of this Lease.
	24.  REMEDIES IN DEFAULT.

		(a)	Upon the occurrence of an Event of Default, Landlord shall
have the option to take any one or more of the following actions without
notice or demand, in addition to and not in limitation of any other remedy
permitted by law or by this Lease.

			(i)	Terminate this Lease, at which time Tenant shall
immediately surrender the Premises to Landlord.  If Tenant fails to do so,
Landlord may expel or remove Tenant and its property and retake possession of
the Premises without liability for any prosecution or any claim for damages
by reason of such re-entry.  Tenant further agrees to indemnify Landlord for
all loss and damage suffered by Landlord by reason of such termination,
including loss of Rent for the remainder of the Term.

			(ii)	Enter upon and take possession of the Premises as
Tenant's agent without terminating this Lease and without liability to
prosecution of any claim for damages by reason of such re-entry, and relet
the Premises as Tenant's agent and receive rent for such reletting.  Tenant
agrees to pay to Landlord on demand for any costs incurred by Landlord
through such reletting, including costs of renovating or repairing the
Premises for a new tenant and for any deficiency that may arise between the
amount of rent due for the remainder of the Term and that received by
Landlord from reletting the Premises.

			(iii)	Landlord may do whatever Tenant is obligated to do
under the terms of this Lease and in order to accomplish this purpose
Landlord may enter the Premises without liability to prosecution or any claim
for damages arising from Landlord's entering the Premises to satisfy Tenant's
obligations under this Lease.  Tenant shall reimburse Landlord for any
expenses Landlord may incur in effecting compliance with this Lease on
Tenant's behalf.  Tenant further agrees that Landlord shall not be liable for
any damages which may result to Tenant from such action by Landlord, whether
caused by Landlord's negligence or otherwise.

		(b)	In the event of any termination of this Lease, Tenant shall
pay the Base Rent, Additional Charges, Taxes, Expenses and all other amounts
payable under this Lease up to the time of such termination, and thereafter
Tenant, until the end of what would have been the Term in the absence of such
termination, and whether or not the Premises shall have been relet, shall be
liable to Landlord for, and shall pay to Landlord, as liquidated current
damages, the Base Rent, Additional Charges, Taxes, Expenses and all other
amounts payable under this Lease had such termination not occurred, less the
net proceeds, if any, of any reletting of the Premises, after deducting all
expenses in connection with such reletting, including, without limitation,
all repossession costs, brokerage commissions, legal expenses, advertising
and marketing costs, expenses of employees, and expenses of preparation for
such reletting.  Tenant shall pay such current damages to Landlord monthly on
the days on which the Base Rent, Additional Charges, Taxes, Expenses and all
other amounts payable under this Lease which would have been payable had this
Lease not been terminated.

		(c)	At any time after the termination of this Lease, whether or
not Landlord shall have collected any current damages pursuant to Section
24(b), as liquidated final damages, and in lieu of all current damages
payable by Tenant pursuant to Section 24(b) thereafter, at Landlord's
election, Tenant shall pay to Landlord an amount which at the time of such
election represents the then value of the excess, if any, of (1) the Base
Rent, Additional Charges, Taxes, Expenses and all other amounts payable under
this Lease which would have been payable by Tenant (conclusively presuming
the annual payments with respect to Base Rent, real estate taxes and expense
escalation obligations to be the same as were payable for the preceding year)
for the period commencing with the date of Landlord's election and ending
with the date contemplated as the expiration date hereof if this Lease had
not so terminated, over (2) the aggregate fair market rental value of the
Premises for the same period.
	25.  EMINENT DOMAIN.
In the event the Building, Premises, or any portion of the Building or the
Premises shall be taken or condemned in whole or in part for public purposes
then the Term shall, at the option of Landlord, forthwith cease and
terminate, and Landlord shall receive the entire award, including any award
for the value of the leasehold estate created under this Lease.  In the event
Landlord does not terminate as herein provided, Rent shall abate in
proportion to the portion of the Premises taken by such condemnation or other
taking.
	26.  ESTOPPEL CERTIFICATE.
  At any time and from time to time but on not less than ten (10) business
days' prior notice by Landlord, Tenant shall promptly execute, acknowledge
and deliver to Landlord, and, at Landlord's request, to any prospective
purchaser, ground lessor, or mortgagee, a certificate certifying (a) that
Tenant has accepted the Premises (or, if Tenant has not done so, that Tenant
has not accepted the Premises and specifying the reasons for not accepting
them); (b) the Commencement and Expiration Dates; (c) that this Lease is
unmodified and in full force and effect (or, if there have been
modifications, that this Lease is in full force and effect as modified and
stating the date and nature of each modification); (d) the dates, if any, to
which Rent has been paid; (e) whether or not there are then existing any
defenses against the enforcement of any of the obligations of Tenant under
this Lease (and, if so, specifying same); (f) whether or not there are then
existing any defaults by Landlord in the performance of its obligations under
this Lease (and, if so, specifying same); and (g) such other matters as may
be reasonably requested by Landlord.  Any such certificate may be relied upon
by Landlord and by any prospective purchaser, ground lessor, or mortgagee
considering the purchase of or a loan on all or any part of the Building or
interest in the Building.  Tenant shall indemnify and hold Landlord harmless
from and against all costs, damages, expenses, liabilities and fees,
including, without limitation, reasonable attorneys' fees and any
consequential damages or lost profits, arising from or in any way related to
or connected with Tenant's failure to deliver any such certificate within the
time specified in this Section 26.
	27.  AUTHORITY OF PARTIES.
If Tenant is a corporation or partnership, each individual executing this
Lease on behalf of Tenant represents and warrants that he is duly authorized
to execute and deliver this Lease on behalf of Tenant, that Tenant is a duly
authorized and existing entity, that Tenant has and is qualified to do
business in Massachusetts, that Tenant has full right and authority to enter
into this Lease, and that this Lease is binding upon such corporation or
partnership in accordance with its terms.  Upon Landlord's request, Tenant
shall provide Landlord with evidence reasonably satisfactory to Landlord
confirming the foregoing representations and warranties.
	28.  BROKERS.
Tenant warrants that it has had no dealings with any real estate broker or
agent in connection with the negotiation of this Lease excepting only the
brokers specified in the Basic Lease Information, and it knows of no other
real estate broker or agent who is entitled to a commission in connection
with this Lease.  Tenant agrees to indemnify Landlord and hold Landlord
harmless from and against any and all claims, demands, losses, liabilities,
lawsuits, judgments, costs and expenses (including reasonable attorneys'
fees) with respect to any leasing commission or equivalent compensation
alleged to be owing on account of Tenant's dealings with any real estate
broker or agent other than as specified in the Basic Lease Information.
	29.  GENERAL PROVISIONS.

		(a)	Waiver.  The waiver by Landlord or Tenant of the other
party's failure to perform or observe any provision of this Lease shall not
be deemed to be a continuing waiver of such provision or a waiver of any
subsequent failure of Landlord or Tenant to perform or observe the same or
any other such provision, and no custom or practice which may develop between
the parties during the Term shall be deemed a waiver of, or in any way
affect, the right of Landlord or Tenant to insist upon performance and
observance by the other party in strict accordance with the terms of this
Lease.

		(b)	Notices.  Any bills, statements, notices, demands, requests
or other communications given or required to be given under this Lease shall
be effective only if rendered or given in writing, sent by a recognized
overnight courier service or delivered personally, (a) to Tenant (i) at
Tenant's address set forth in the Basic Lease Information, if sent prior to
Tenant's taking possession of the Premises, or (ii) at Tenant's address at
the Building, if sent subsequent to Tenant's taking possession of the
Premises, or (iii) at any place where Tenant or any agent or employee of
Tenant may be found if sent subsequent to Tenant's vacating, deserting,
abandoning, or surrendering the Premises, or (b) to Landlord at Landlord's
address set forth in the Basic Lease Information, or (c) to such other
address as either Landlord or Tenant may designate as its new address for
such purpose by notice given to the other in accordance with the provisions
of this Section 29(b).  Any such bill, statement, notice, demand, request or
other communication shall be deemed to have been rendered or given one (1)
day after the date when it shall have been mailed as provided in this
Section 29(b) if sent by a recognized overnight courier service, or upon the
date personal delivery is made or refused.  If Tenant is notified of the
identity and address of Landlord's mortgagee or ground or underlying lessor,
Tenant shall give to such mortgagee or ground or underlying lessor notice of
any default by Landlord under the terms of this Lease in writing sent by a
recognized overnight courier service, and such mortgagee or ground or
underlying lessor shall be given a reasonable opportunity to cure such
default prior to Tenant exercising any remedy available to it.

		(c)	Examination of Lease.  Submission of this instrument to
Tenant for its execution does not constitute a reservation, offer or option
for a lease, and this instrument is not and shall not be deemed to be
effective as a lease or otherwise until its execution and delivery by both
Landlord and Tenant.  This Lease may be executed in counterparts and, when
all counterpart documents are executed, the counterparts shall constitute a
single binding instrument.

		(d)	Captions.  The captions of this Lease are for convenience
of reference only and shall have no effect upon the construction or
interpretation of any provision of this Lease.

		(e)	Definitions.  The words "Landlord" and "Tenant" as used
herein shall include the plural as well as the singular.  The words used in
the neuter gender include the masculine and feminine.  If the Tenant is more
than one entity, the obligations under this Lease imposed on Tenant shall be
joint and several.

		(f)	Time.  Time is of the essence of this Lease and each and
all of its provisions in which performance is a factor.

		(g)	Successors and Assigns.  The terms, covenants and
conditions contained in this Lease shall bind and inure to the benefit of
Landlord and Tenant and, except as otherwise provided herein, their
respective personal representatives and successors and assigns; provided,
however, upon the sale, assignment or transfer by the Landlord named herein
(or by any subsequent landlord) of its interest in the Building as owner or
lessee, including any transfer by operation of law, the Landlord named herein
(or any subsequent landlord) shall be relieved from all subsequent
obligations or liabilities under this Lease, and all obligations subsequent
to such sale, assignment or transfer (but not any obligations or liabilities
that have accrued prior to the date of such sale, assignment or transfer)
shall be binding upon the grantee, assignee or transferee of such interest,
and any such grantee, assignee or transferee, by accepting such interest,
shall be deemed to have assumed such subsequent obligations and liabilities.

		(h)	Recordation.  Tenant may record a notice of this Lease in
the form of Exhibit F hereto.  In the event that a notice of Lease is
consented to by Landlord and such notice of Lease is recorded, Tenant agrees
to execute a discharge or release of such notice of Lease upon the expiration
or earlier termination of this Lease.  Tenant further agrees that should
Tenant fail to execute such discharge or release, that Tenant shall appoint
Landlord its attorney-in-fact and give Landlord such power of attorney for
the sole purpose of executing a discharge or release of such notice of Lease
on behalf of Tenant.

		(i)	Quiet Possession.  Upon Tenant paying the Rent reserved
under this Lease and observing and performing all of the provisions of this
Lease, Tenant shall have quiet possession of the Premises for the entire
Term, subject to all the provisions of this Lease.

		(j)	Prior Agreements.  This Lease contains all of the
agreements of the Landlord and Tenant with respect to any matter covered or
mentioned in this Lease, and no prior agreements or understandings pertaining
to any such matters shall be effective for any purpose.  No provision of this
Lease may be amended or added to except by an agreement in writing signed by
the parties or their respective successors in interest.  Tenant acknowledges
that in executing and delivering this Lease, Tenant is not relying on any
verbal or written understanding, promise or representation outside the scope
of this Lease and not described or referred to herein.

		(k)	Attorneys' Fees.  In the event of any action or proceeding
brought by either party against the other under this Lease, the prevailing
party shall be entitled to recover all costs and expenses including its
attorneys' fees in such action or proceeding in such amount as the court may
adjudge reasonable.  The prevailing party shall be determined by the court
based upon an assessment of which party's major arguments made or positions
taken in the proceedings could fairly be said to have prevailed over the
other party's major arguments or positions on major disputed issues in the
court's decision.  If the party which shall have commenced or instituted the
action, suit or proceeding shall dismiss or discontinue it without the
concurrence of the other party, such other party shall be deemed the
prevailing party.

		(l)	Subordination; Attornment.  Without the necessity of any
additional document being executed by Tenant for the purpose of effecting a
subordination, this Lease shall be subject and subordinate at all times to:
(i) all ground leases or underlying leases which may now exist or hereafter
be executed affecting the Building or the Land or both, and (ii) the lien of
any mortgage or deed of trust which may now exist or hereafter be executed in
any amount for which the Building, Land, ground leases or underlying leases
or Landlord's interest or estate in any of such liens is specified as
security, provided that the lessees under such ground or underlying leases,
and the mortgagees or beneficiaries named in such mortgages or deeds of
trust, shall agree to recognize the interest of Tenant under this Lease in
the event of foreclosure, if Tenant is not then in default.  Landlord agrees
to use commercially reasonable efforts to obtain and deliver to Tenant a non-
disturbance agreement executed and delivered by Landlord's fee
mortgagee/lender, in said fee mortgagee/lender's standard form.
Notwithstanding the foregoing, Landlord shall have the right to subordinate
or cause to be subordinated any such ground leases or underlying leases or
any such liens to this Lease.  In the event that any ground lease or
underlying lease terminates for any reason or any mortgage or deed of trust
is foreclosed or a conveyance in lieu of foreclosure is made for any reason,
Tenant shall, notwithstanding any subordination, attorn to and become the
Tenant of the successor in interest to Landlord, at the option of such
successor in interest.  The provisions of this paragraph shall be self-
operative and no further instrument shall be required to effect the
provisions of this paragraph.  Notwithstanding the foregoing, Tenant
covenants and agrees to execute and deliver, upon demand by Landlord and in
the form requested by Landlord, any additional documents evidencing the
priority or subordination of this Lease with respect to any such ground
leases or underlying leases or the lien of any such liens.

		(m)	Names.  Tenant shall not use the name of the Building or of
the development in which the Building is situated for any purpose other than
as an address of the business to be conducted by Tenant in the Premises.

		(n)	Separability.  Any provision of this Lease which shall
prove to be invalid, void, illegal or unenforceable shall in no way affect,
impair or invalidate any other provisions of this Lease, and such other
provisions and this Lease shall remain in full force and effect.

		(o)	Cumulative Remedies.  No remedy or election under this
Lease shall be deemed exclusive but shall, wherever possible, be cumulative
with all other remedies at law or in equity.

		(p)	Choice of Law.  This Lease shall be governed by and
construed in accordance with the laws of the Commonwealth of Massachusetts.

		(q)	Signs and Building Name.  Tenant shall not place any sign
upon the Premises, Building or Land without Landlord's prior consent, such
consent not to be unreasonably withheld, delayed or conditioned.  All signs
so consented to by Landlord and placed by Tenant upon or in the Premises
shall comply in all respects with size, design, lettering and material
guidelines established by Landlord for the Building.  Landlord reserves the
right to change or alter such guidelines at such times and for such tenants
as Landlord may determine in its sole and absolute discretion.

		(r)	No Merger.  The voluntary or other surrender of this Lease
by Tenant, or a mutual cancellation of this Lease, shall not constitute a
merger, and shall, at the option of Landlord, terminate all or any existing
subleases or subtenancies or may, at the option of Landlord, operate as an
assignment to Landlord of any or all such subleases or subtenancies.

		(s)	Jury Trial.  Tenant and Landlord waive the right to a jury
trial in any action brought under this Lease or arising out of the
landlord/tenant relationship.

		(t)	Force Majeure.  In the event Landlord shall be delayed,
hindered, or prevented from the performance of any act required under this
Lease by reason of act of God; act of common enemy; fire, storm, flood,
explosion or other casualty; strike, lockouts, labor disputes, labor
troubles; inability to procure materials; failure of power; restrictive
governmental laws or regulations; riots; insurrection; war; settlement of
losses with insurance carriers; injunction; order of any court or
governmental authority; or other cause not within the reasonable control of
Landlord, then the performance of such act shall be excused for the period of
the delay and the period for the performance of any such act shall be
extended for a period equivalent to the period of such delay.

		(u)	Financial Statements.  Upon Landlord's written request from
time to time (but not more frequently than once per year), Tenant shall
promptly furnish Landlord with certified financial statements reflecting
Tenant's then-current financial condition, in such form and detail as
Landlord may reasonably request; provided, however, that if the stock of
Tenant is traded on a national exchange, Tenant may furnish a copy of the
annual report filed with the Securities and Exchange Commission instead of
financial statements.

		(v)	Compliance with Americans with Disabilities Act.
Notwithstanding any provision of this Lease to the contrary, Tenant is and
shall be solely responsible for assuring that the Premises at all times
comply in full with the Americans with Disabilities Act, 42 USC Section 12181
et seq. (the "Act") as now or hereafter amended, and all regulations now or
hereafter promulgated pursuant to the Act (the "Regulations"), including but
not limited to any remodeling or alterations done to the Premises.  Tenant is
and shall be solely responsible for all costs and expenses associated with
complying with the Act and the Regulations, whether such expenditures are
capital or otherwise.  Tenant acknowledges that Landlord makes no
representations or warranties regarding the Premises' compliance with the Act
or Regulations.  Tenant shall indemnify and defend Landlord against, and hold
Landlord harmless from any and all claims, demands, causes of action, suits,
lawsuits, costs and expenses (including, but not limited to, reasonable
attorneys' fees and litigation costs), damages, penalties and fines asserted
against, or suffered or incurred by, Landlord in any way relating to or
arriving from, in whole or in part, an actual or asserted claim that Premises
or any portion of the Premises, is in violation of the Act or the
Regulations.

		(w)	Limitation on Landlord Liability.  Neither the
shareholders, investors, officers, directors, trustees, employees,
individuals, or partners comprising Landlord, nor the shareholders,
investors, directors, trustees, officers, or partners of any of the foregoing
(collectively, the "Parties") shall be liable for the performance of
Landlord's obligations under this Lease.  Tenant shall look solely to
Landlord to enforce Landlord's obligations under this Lease and shall not
seek any damages against any of the Parties.  Tenant shall not look to the
property or assets of Landlord, excepting only the Building, or of any of the
Parties, in seeking to enforce Landlord's obligations under this Lease or to
satisfy a judgment for Landlord's failure to perform such obligations.

		(x)	Exhibits.  The Exhibits listed in the Table of Contents to
this Lease are incorporated herein by reference and shall be read and
construed as if they formed a part hereof.

EXHIBIT D

PREVAILING MARKET RATE
DETERMINATION PROCEDURE
If Landlord exercises its option to adjust the Base Rent pursuant to
paragraph "c" in the definition of "Base Rent" set forth in the Basic
Lease Information, the "Prevailing Market Rate" shall be determined as set
forth below.
As used herein, the term "Prevailing Market Rate" for the Premises
shall mean the rental and all other monetary payments and escalations,
including, without limitation, consumer price indexing, that Landlord
could obtain from an arm's length third party desiring to lease the
Premises as of the date at which Base Rent is to be adjusted (the "Base
Rent Adjustment Date") taking into account the age of the Building, the
size of the Premises, the quality of construction of the Building and the
Premises, the services provided under the terms of this Lease, the rental
then being obtained for new leases of space comparable to the Premises in
the locality of the Building, and all other factors that would be relevant
to a third party desiring to lease the Premises as of the Base Rent
Adjustment Date in determining the rental such party would be willing to
pay therefor; provided, however, that no allowance for the construction of
tenant improvements shall be taken into account in determining the
Prevailing Market Rate.  No later than one hundred twenty (120) days prior
to the Base Rent Adjustment Date, Landlord shall notify Tenant of
Landlord's determination of the Prevailing Market Rate to be used to
calculate the Base Rent after the Base Rent Adjustment Date.  If Tenant
wishes to dispute Landlord's determination Tenant shall give notice to
Landlord, within thirty (30) days after receipt of notice of Landlord's
determination, of Tenant's intent to submit the matter to the appraisal
process described below.  If Tenant so elects, then within fifteen (15)
days after the date of Tenant's notice of its election to submit the
matter to the appraisal process, each party, at its sole cost, shall
engage a real estate appraiser to act on its behalf in determining the
Prevailing Market Rate for the Premises as of the Base Rent Adjustment
Date.  The appraisers shall have at least five (5) years' commercial
experience in the metropolitan area in which the Building is located, be
designated as an MAI appraiser, and shall be persons who would qualify as
expert witnesses over objection to give opinion testimony on the issue of
the Prevailing Market Rate for the Premises in a court of competent
jurisdiction.  If a party does not appoint an appraiser within fifteen
(15) days after the other party has given written notice to the non-
appointing party of the name of its appraiser, the single appraiser
appointed shall be the sole appraiser and shall set the Prevailing Market
Rate for the Premises as of the Base Rent Adjustment Date.  If the two
appraisers are appointed by the parties in accordance with this Exhibit D,
such appraisers shall meet promptly and attempt to set the Prevailing
Market Rate for the Premises as of the Base Rent Adjustment Date.  If such
appraisers are unable to agree within thirty (30) days after appointment
of the second appraiser, the appraisers shall elect a third appraiser
meeting the qualifications stated in this Exhibit D within ten (10) days
after the last date the two appraisers are given to set the Prevailing
Market Rate for the Premises.  If the two appraisers are unable to agree
on the third appraiser, either party may apply to the Superior Court in
the county in which the Building is located, to appoint said third
appraiser.  Each of the parties shall bear one-half (1/2) the cost of
appointing the third appraiser and of paying the third appraiser's fee.
The third appraiser shall be a person who has not previously acted in any
capacity for either party.  Within thirty (30) days after the selection of
the third appraiser, the Prevailing Market Rate for the Premises as of the
Base Rent Adjustment Date shall be fixed by the three appraisers in
accordance with the following procedures.  Each of the appraisers selected
by the parties shall state, in writing, his or her determination of the
Prevailing Market Rate for the Premises as of the Base Rent Adjustment
Date supported by the reasons therefor and shall make counterpart copies
for each of the other appraisers.  The appraisers shall arrange for a
simultaneous exchange of such proposed resolutions.  The role of the third
appraiser shall be to select which of the two proposed resolutions most
closely approximates his or her determination of Prevailing Market Rate
for the Premises as of the Base Rent Adjustment Date.  The third appraiser
shall have no right to propose a middle ground or any modification of
either of the two proposed resolutions.  The resolution he chooses as that
most closely approximating his determination of the Prevailing Market Rate
for the Premises as of the Base Rent Adjustment Date shall constitute the
decision of the appraisers and shall be final and binding upon the
parties.  If either by agreement of the parties or by appraisal the
Prevailing Market Rate is not finally determined by the Base Rent
Adjustment Date, then Tenant shall continue to pay the monthly Base Rent
in effect for the annual period immediately prior to the Base Rent
Adjustment Date until such time as the Prevailing Market Rate is finally
determined by agreement of the parties or by an appraiser.  If the monthly
Prevailing Market Rate as finally determined as of the Base Rent
Adjustment Date exceeds the monthly amount previously paid by Tenant for
said period following the Base Rent Adjustment Date, Tenant shall
forthwith pay the difference to Landlord for each of the months Tenant
paid the lesser amount.  Notwithstanding the provisions set forth above in
this Exhibit D, in the event that said provisions result in a Prevailing
Market Rate which is below the amount of Base Rent paid by Tenant during
the year of the Lease Term immediately preceding the Base Rent Adjustment
Date the Prevailing Market Rate shall be the Base Rent paid by Tenant
during said year of the Lease Term immediately preceding the Base Rent
Adjustment Date.  Once determined, the Prevailing Market Rate (expressed
on a per square foot basis) shall be deemed to be substituted for the rate
of Base Rent set forth in paragraph "a" of the definition of Base Rent set
forth in the Basic Lease Information section hereof and Tenant shall pay
said revised rate in accordance with the terms of this Lease from and
after the Base Rent Adjustment Date.

NOW,  THEREFORE,  the  parties to this Amendment hereby agree that the Executive
Stock  Agreement  is  amended  and  restated  to  read  as  follows:

     THIS  AGREEMENT  is  made  as  of  April  2, 1998, between Ranger Aerospace
Corporation,  a  Delaware  corporation  (the  "Company")  and  Stephen D. Townes
                                               --------
("Executive").

     The Company and the Executive desire to enter into an agreement pursuant to
which  Executive  shall  purchase, and the Company shall sell, 2,663 shares (the
"Purchased  Shares")  of  the Company's Class A Common Stock, par value $.01 per

                                                     --------------
shares  of  Company  Stock and all shares of Company Stock hereafter acquired by
Executive  are  referred to herein as "Executive Stock." Certain definitions are
                                       ----------------
set  forth  in  paragraph  7  of  this  Agreement.

     NOW,  THEREFORE, in consideration of the mutual covenants contained herein,
and  for  other  good and valuable consideration, the receipt and sufficiency of
which  is  hereby  acknowledged,  the  parties  hereto  agree  as  follows:

     1.     Purchase  and  Sale  of  Executive  Stock.
            -----------------------  ----------------

     (a)     Upon execution of this Agreement, Executive shall purchase, and the
Company  shall sell, 2,663 shares of Class A Common Stock at a price of $100 per
share.  The Company shall deliver to Executive the certificate representing such
shares of Company Stock, and Executive shall deliver to the Company a promissory
note  in the form of Annex A attached hereto in an aggregate principal amount of
                     -------
$266,300 (the "Executive Note"). Executive's obligation under the Executive Note
               ----------------
shall  be  secured  by  a  pledge  of  the  2,663 shares of Class A Common Stock
purchased  by  Executive  hereunder and in connection therewith, Executive shall
enter  into  a  pledge  agreement  in  the  form  of  Annex  B  attached hereto.

     (b)     Within  30  days  after Executive purchases any shares of Executive
Stock  from  the  Company  hereunder, Executive shall make an effective election
with  the  Internal  Revenue Service under Section 83(b) of the Internal Revenue
Code and the regulations promulgated there-under in the form of Annex C attached
                                                                -------
hereto  and  any  similar  filing  required  by  applicable  state  law.

<PAGE>

     (c)     In  connection  with  the  purchase and sale of the Executive Stock
hereunder,  Executive  represents  and  warrants  to  the  Company  that:

     (i)     The  Executive  Stock  to be acquired by Executive pursuant to this
Agreement  shall be acquired for Executive's own account and not with a view to,
or  intention  of,  distribution  thereof  in  violation of the 1933 Act, or any
applicable  state securities laws, and the Executive Stock shall not be disposed
of  in  contravention  of  the 1933 Act or any applicable state securities laws.

     (ii)     Executive  is  sophisticated  in  financial matters and is able to
evaluate  the  risks  and  benefits  of  the  investment in the Executive Stock.

     (iii)     Executive  is able to bear the economic risk of his investment in
the Executive Stock for an indefinite period of time. Executive understands that
the  Executive  Stock has not been registered under the 1933 Act and, therefore,
cannot be sold unless subsequently registered under the 1933 Act or an exemption
from  such  registration  is  available.

     (iv)     Executive  has  had  an  opportunity  to ask questions and receive
answers  concerning  the terms and conditions of the offering of Executive Stock
and  has had full access to (A) such other information concerning the Company as
he has requested and (B) such other information which is necessary and desirable
to  make  an  informed  investment  decision regarding the purchase of Executive
Stock  hereunder. Executive has reviewed a copy of the Share Purchase Agreement,
dated  as  of  March  14,  1998  and  amended as of the date hereof, between the
Company,  Viad  Corp.  and  Viad  Service Company, Limited pursuant to which the
Company  acquired  substantially  all  of  the  stock of certain subsidiaries of
Aircraft  Service  International Group, Inc. and the Security Purchase Agreement
dated  as  of  the  date  hereof,  between the Company, John Hancock Mutual Life
Insurance  Company  and CIBC Wood Gundy Ventures, Inc. and Executive is familiar
with  the  transactions  contemplated  thereby.

     (v)     This  Agreement constitutes the legal, valid and binding obligation
of  Executive,  enforceable  in  accordance  with  its terms, and the execution,
delivery  and  performance  of  this Agreement by Executive do not and shall not
conflict  with,  violate  or  cause  a  breach  of  any  agreement,  contract or
instrument  to  which  Executive  is a party or any judgment, order or decree to
which  Executive  is  subject.

     (d)     As  an  inducement  to  the Company to issue the Executive Stock to
Executive,  and  as a condition thereto, Executive acknowledges and agrees that:

     (i)     neither  the  issuance  of the Executive Stock to Executive nor any
provision  contained  herein shall entitle Executive to remain in the employment
of  the  Company  or  its  Subsidiaries  or  affect  the right of the Company to
terminate  Executive's  employment  at  any  time;  and

     (ii)     the  Company  shall  have  no  duty  or  obligation to disclose to
Executive,  and  Executive  shall  have  no right to be advised of, any material
information regarding the Company or its Subsidiaries at any time prior to, upon
or  in connection with the repurchase of Executive Stock upon the termination of
Executive's  employment  with  the  Company  or its Subsidiaries or as otherwise
provided  hereunder.

     (e)     The Company and Executive acknowledge and agree that this Agreement
has  been  executed  and  delivered,  and  the  Executive  Stock has been issued
hereunder,  in  connection  with and as a part of the compensation and incentive
arrangements  between  the  Company  and  Executive.

     2.     All Executive Stock purchased hereunder shall become fully vested on
March  7,  2000.

     3.     Repurchase  Option.
            ------------------

<PAGE>

     (a)     In  the event Executive ceases to be employed by the Company or its
Subsidiaries  (the  "Termination") for any reason, the Purchased Shares (whether
                     -----------
held by Executive or one or more of Executive's transferees) shall be subject to
repurchase by the Company pursuant to the terms and conditions set forth in this
paragraph  3  (the  "Repurchase  Option").
                     ------------------

     (b)     The  purchase  price  for  each share of Purchased Shares purchased
pursuant  to  this  paragraph  3  shall  be  the Fair Market Value of such share
(determined  as of the date of the Repurchase Notice, or if no Repurchase Notice
is  given,  as  of  the  last  day  of  the  Company  Election  Period).

     (c)     The  Company  may elect to purchase all or any portion of Purchased
Shares  by delivery of written notice (the "Repurchase Notice") to the holder(s)
                                            -----------------
of  Purchased  Shares  within  45 days after the Termina-tion Date (the "Company
                                                                         -------
Election Period"). The Repurchase Notice shall set forth the number of shares of
   ------------
each  class of the Purchased Shares to be acquired from each holder of Purchased
Shares,  the aggregate consideration to be paid for such shares and the time and
place for the closing of the transaction. The number of shares to be repurchased
by  the  Company shall first be satisfied to the extent possible from the shares
of  Purchased Shares held by Executive at the time of delivery of the Repurchase
Notice.  If  the  number of shares of Purchased Shares then held by Executive is
less than the total number of shares of Purchased Shares the Company has elected
to  purchase,  the  Company  shall  purchase  the remaining shares elected to be
purchased from the other holder(s) of Purchased Shares under this Agreement, pro
rata  according  to  the number of shares of Purchased Shares held by such other
holder(s) at the time of delivery of such Repurchase Notice (determined as close
as  practicable  to  the  nearest  whole  shares).

     (d)     If for any reason the Company does not elect to purchase all of the
Unvested  Stock  pursuant  to  the  Repurchase  Option,  the  Investors shall be
entitled  to  exercise  the Repurchase Option for the shares of Purchased Shares
the  Company  has  not elected to purchase (the "Available Shares").  As soon as
                                                 ---------
practica-ble  after  the  Company  has  determined  that there will be Available
Shares,  but  in  any event within 5 days after the Company Election Period, the
Company shall give written notice (the "Option Notice") to the Investors setting
                                        -------------
forth  the  number and class of Available Shares and the purchase price for each
Available  Share.  The  Investors  may elect to purchase any number of Available
Shares  by  delivering  written  notice  (the  "Election Notice") to the Company
                                                ----------------
within  30  days  after  receipt of the Option Notice from the Company; provided
                                                                        --------
that  if  more  than one Investor elects to purchase any or all Available Shares
and  the  number  of  Available  Shares  is  less  than  the aggregate number of
Purchased  Shares  elected  to  be  purchased  by  such electing Investors, each
Investor shall be entitled to purchase the lesser of (i) the number of shares of
such  class  that  such  Investor  has  elected  to purchase as indicated in the
Election  Notice  or  (ii)  the  number  of  shares  of  such class ob-tained by
multiplying  the  number of shares specified in the Option Notice by a fraction,
the  numerator  of  which is the number of shares of such class of Company Stock
(on a fully-diluted basis) held by such Investor and the denominator of which is
the  aggregate  number  of  Shares  of  such  class  of  Company  Stock  (on  a
fully-diluted  basis) held by all electing Investors. In the event all Available
Shares  are not purchased by the Investors pursuant to the immediately preceding
sentence,  the  Available  Shares  remaining  to be purchased shall be allocated
among the Investors who elect to purchase more Available Shares (as indicated in
their  respective  Election Notices) than they are entitled to purchase pursuant
to  the  immediately preceding sentence as the Investors shall agree in writing.
As  soon  as practicable, and in any event within 5 days after the expiration of
the  30-day  period  set  forth  above,  the Company shall notify each holder of
Purchased  Shares as to the number of shares being purchased from such holder by
the  Investors  (the  "Supplemental Repurchase Notice"). At the time the Company
                       --------------------------------
delivers  the  Supplemental  Repurchase  Notice  to  the  holder(s) of Purchased
Shares,  the  Company shall also deliver written notice to each Investor setting
forth  the number of shares such Investor is entitled to purchase, the aggregate
purchase  price  and  the  time  and  place  of  the closing of the transaction.

     (e)     The purchase of Purchased Shares pursuant to this paragraph 3 shall
be  closed  at  the  Company's  executive  offices  on  a date determined by the
Company,  which date shall be within 60 days after the expiration of the Company
Election  Period.  The  Company and/or the Investors shall pay for the Purchased
Shares  to be purchased pursuant to the Repurchase Option by delivery of, in the
case of each Investor, a check or wire transfer of funds and, in the case of the
Company  at its option, (1) cancellation or exchange of the Executive Note, (ii)
a check or wire transfer of funds, (iii) a subordinated note or notes payable in
up to, three equal annual installments beginning on the first anniversary of the
closing  of such purchase and bearing interest (payable quarterly) at a rate per
annum  equal  to  the  interest rate then being charged to the Company under any
revolving working capital credit facility, or (iv) any combination of (i)-(iii),
in the aggregate amount of the purchase price for such shares; provided that the
                                                               -------- ----

<PAGE>

Company  shall  use reasonable efforts to make all such repurchases in excess of
the  amount due under any Executive Note with a check or wire transfer of funds.
Any notes issued by the Company pursuant to this paragraph 3(e) shall be subject
to  any restrictive covenants to which the Company or any of its subsidiaries is
subject  at  the  time  of  such  purchase.  In  addition  to offsetting amounts
outstanding  under  the  Executive  Note  issued  to  the Company hereunder, the
Company  may pay the purchase price for such shares by offsetting any other bona
fide  debts owed by Executive to the Company. The purchasers of Purchased Shares
hereunder  shall be entitled to receive customary representations and warranties
from  the  sellers  regarding such sale of shares (including representations and
warranties  regarding  good title to such shares, free and clear of any liens or
encumbrances) and to require all sellers' signatures be guaranteed by a national
bank  or  reputable  securities  broker.

     (f)     The  right of the Company and the Investors to repurchase Purchased
Shares  pursuant  to this paragraph 3 shall terminate upon the expiration of the
time  periods  within  which  the  Company  and  the  Investors have to elect to
repurchase  the  Purchased  Shares set forth in paragraphs 3(c) and 3(d) hereof,
and  otherwise  shall  not  terminate.

     (g)     Notwithstanding  anything  to  the  contrary  contained  in  this
Agreement,  all  repurchases of Purchased Shares by the Company shall be subject
to applicable restrictions contained in the Delaware General Corporation Law and
in  the  Company's and its Subsidiaries debt and equity financing agreements. If
any  such  restrictions  prohibit  the  repurchase of Purchased Shares hereunder
which  the  Company  is otherwise entitled or required to make, the time periods
provided  in  this paragraph 3 shall be suspended, and the Company may make such
repurchases  as soon as it is permitted to do so under such restrictions. If the
repurchase  of  Purchased  Shares  is  delayed as contemplated in this Paragraph

(i)  by  cancellation  of  the  Executive  Note  and/or  any  other  outstanding
indebtedness  of  the  Executive to the Company in an amount no greater than the
Put  Price for such shares, and thereafter, (ii) by cashier's or certified check

Agreement, all repurchases of Executive Stock by the Company shall be subject to
applicable restrictions contained in the Delaware General Corporation Law and in
the  Company's and its Subsidiaries debt and equity financing agreements. If any
such restrictions prohibit the repurchase of Executive Stock hereunder which the
Company  is otherwise entitled or required to make, the time periods provided in
this  paragraph  4 shall be suspended, and shall recommence when the Company may
make  such  repurchases  under such restrictions. If the repurchase of Executive
Stock  is delayed as contemplated in this Paragraph 4(f), the Put Price shall be
equal  to  the  Fair  Market Value of the Executive Stock on the date of the Put
Notice  plus  interest  accruing over the period of delay equal to the lesser of
9.5% per annum, compounded annually, computed on the basis of a 360 day year and
the  actual  number  of days elapsed or the maximum rate permitted by applicable
law.

     (g)     Notwithstanding  anything  contained  herein  to  the  contrary,
Executive  shall  not  have  the  right to require the Company to repurchase any
shares  held by the Executive, pursuant to this Paragraph 4, other than pursuant
