Property or the Building, except those due to the act or omission of Tenant,
its agents, employees, invitees and contractors; or (ii) from any accident,
injury or damage occurring in or about the Premises where such accident,
damage or injury results or is claimed to have resulted from any act or
omission on the part of Landlord or Landlord's agents, employees, invitees and
contractors in either case, occurring at any time from the execution of this
Lease through the end of the Term or any Extended Term of this Lease.  This
indemnity and hold harmless agreement shall included indemnity against all
reasonable costs, expenses and liabilities incurred in, or in connection with,
any such claim or proceeding brought thereon and the defense thereof,
including, without limitation, reasonable attorneys' fees at both the trial
and appellate levels and shall survive the expiration or sooner termination of
the Term of this Lease.  This indemnity shall not apply to protect Tenant from
acts in breach of this Lease.

                          ARTICLE XV
                TENANT'S LIABILITY INSURANCE

Tenant shall maintain with respect to the demised premises, and to the
property of which the demised premises are a part, comprehensive public
liability insurance in limits of not less than $500,000/500,000, with property
damage insurance in limits of not less than $100,000 in responsible companies
qualified to do business in Massachusetts, and in good standing therein,
insuring against injury to persons or damage to property, as herein provided,
and naming Landlord and Tenant as insureds as their interests may appear. 
Tenant shall deposit with Landlord certificates of each policy of insurance
required by this Lease at, or prior to, the commencement of the Term, and
thereafter, within thirty (30) days prior written notice to each insured named
therein.

                     ARTICLE XVI
          FIRE, CASUALTY; EMINENT DOMAIN

Should the demised premises, or the Building, of which they are a part, be
damaged substantially by fire, or other casualty, or be taken in whole, or
part, by eminent domain, Lessor or Tenant may elect within thirty (30) days
after such casualty, or taking (notwithstanding that Landlord's entire
interest may have been divested by any such taking) to terminate this Lease. 
When such fire, casualty, or taking, renders the demised premises
substantially unsuitable for their intended use, a just and proportionate
abatement of rent shall be made, according to the nature and extent of the
damage, until the demised premises shall be restored by Landlord and Tenant
may elect to terminate this Lease, if Landlord fails to restore the demised
premises to a condition substantially suitable for their intended use, within
one hundred twenty (120) days after said fire, casualty, or taking; provided
that Tenant's notice shall be given within fifteen (15) days after said one
hundred twenty (120) day period.  Landlord's obligation to restore shall be
limited to insurance, or taking proceeds recovered, or recoverable, and made
available by Landlord's Mortgagees.

Landlord reserves, and Tenant hereby grants and assigns to Landlord, all
rights, which Tenant may have, for damages or injury to the demised premises,
or to the leasehold hereby created for any taking by eminent domain, except
for moving expenses, which may be separately awarded to Tenant, by taking the
authority.  Tenant shall execute and deliver to Landlord such confirmatory
instruments of this assignment as Landlord may, from time to time, request.

Each policy of insurance maintained by Landlord, or Tenant (whether or not
required under the provisions of this Lease), with respect to the demised
premises, or with respect to such party's property or improvements therein,
shall include provisions by which the insurance carrier(s); (a) waive(s) all


                             9
<PAGE>
<PAGE>

rights of subrogation against the other party (and against all those for whom
it may be legally responsible), on account of any loss payable under the
policy, and (b) agree(s) that the policy will not be invalidated because the
insured (in writing, and prior to the occurrence of any loss under the policy)
has waived part, or all, of its rights) of recovery against any party on
account of any loss or damage covered by the policy.  If either party is
unable to procure the inclusion of either of the clauses described in the
preceding sentence, without additional cost to it, it shall name the other
party as an additional insured in the policy, at its election, the other party
to pay an additional cost to be so added.

                     ARTICLE XVII
          TENANT'S DEFAULT AND BANKRUPTCY

In the event that:

(a) Tenant shall default in the payment of any installment of rent, or other
sum herein specified, and such default shall continue for ten (10) days after
receipt of written notice; or

(b) Tenant shall default in the observance, or performance, of any other
Tenant's covenants, agreements, or obligations hereunder and such default
shall not be corrected within twenty (20) days after receipt of written notice
thereof; or

(c) Tenant, or any guarantor of Tenant's obligations here under, shall be
declared bankrupt, or insolvent, according to law, or, if any assignment shall
be made of Tenant's property for the benefit of creditors, or by other process
of law, or if any proceedings for reorganization, or for an arrangement with
creditors, shall be commenced under any bankruptcy, or insolvency law, by, or
against Tenant, or any such guarantee, or any person or entity occupying the
demised premises, through or under Tenant (and as to involuntary proceedings
shall remain pending for at least ninety (90) days), then Landlord shall have
the right, at its sole election, either (i) without necessity or requirement
for making any entry, provide Tenant, which termination shall take effect on
the date, prior to the expiration of the Term, specified in Landlord's notice,
or (ii) to enter and take possession of the demised premises (or any part
thereof in the name of the whole) without demand or notice and repossess the
same as of Landlord's former estate, expelling Tenant and those claiming under
it, forcibly, if necessary, without being deemed guilty of any manner of
trespass, provided that such repossession shall not be construed to effect a
termination of this Lease, unless Landlord so declares as part of such entry,
or sends Tenant a written notice of termination, as provided above.  Any such
termination or entry shall be without prejudice to any remedy for arrears of
rent or preceding breach of contract.

If Landlord shall terminate this Lease, or take possession of the demised
premises, as aforesaid, Tenant, and those claiming under Tenant, shall
forthwith remove their goods and effects from the demised premises, and Tenant
agrees that in case of such termination, it shall, at the election of Landlord
(i) indemnify Landlord from, and against, any loss and damage sustained by
reason of any termination caused by the default of, or the breach by, Tenant.

Landlord's damages hereunder shall include, but shall not be limited to, any
loss of rents, reasonable broker's commissions for the re-letting of the
demised premises, advertising costs, the reasonable cost incurred in cleaning
and repainting the premises, in order to re-let the same; and moving and
storage charges incurred by Landlord in moving Tenant's belongings, all of
which Tenant agrees Landlord shall have the right to do or incur; and (ii) at
any time after such termination forthwith pay to Landlord, upon request, as
damages hereunder a sum equal to the present value of the amount by which the
rent and other payments called for hereunder for the remainder of the Term, or
any extension or renewal thereof.

                           10
<PAGE>
<PAGE>

Not more than seven (7) days after receipt of Landlord's bill therefore,
Tenant shall pay for Landlord all costs and expenses (including, without
limitation, reasonable attorney's fees) incurred by Landlord, at any time, in
enforcing tenant's obligations, or Landlord's rights, under this Lease.

                     ARTICLE XVIII
                     NOTICE

Any notice from Landlord to Tenant relating to the demised premises, or to the
occupancy thereof, shall be deemed duly served, if hand delivered to the
demised premises, or mailed to said premises, registered or certified mail,
return receipt requested, postage prepaid, addressed to Tenant, or to such
other address as may designate from time to time.  Any notice from Tenant to
Landlord relating to the demised premises shall be deemed duly served, if
mailed to Landlord by registered or certified mail, return receipt requested,
postage prepaid, and addressed to Landlord at the place where rent is payable
hereunder, or to such other address as Landlord may, from time to time,
designate in like manner.

Any notice, which is mailed in accordance with the provisions of this Article,
shall be deemed to have been received on the third business day following the
date of mailing.

                     ARTICLE XIX
                SURRENDER; YIELD UP

Tenant shall, at the expiration or other termination of this Lease, remove all
of Tenant's goods and effects from the demised premises, (including, without
hereby limiting the generality of the foregoing, all signs and lettering
affixed or painted by Tenant, either inside or outside the demised premises)
and shall leave the same in broom clean condition.  Tenant shall deliver to
Landlord the demised premises and all keys, locks thereto, and other fixtures
connected therewith, and all alterations and additions made to, or upon, the
demised premises except those alterations or additions consented to by
Landlord, in the same order, repair and condition as they are in on the
Commencement Date, or they have been put during the Term hereof, reasonable
wear and tear, and damage by fire or other casualty, and taking only excepted.

In the event of Tenant's failure to remove any of Tenant's property from the
demised premises, Landlord is hereby authorized, without liability to Tenant,
for loss or damage thereto, and, at the sole risk of Tenant, to remove and
store any of the property at Tenant's expense, or to retain the same under
Landlord's control, or to sell, at public or private sale, without notice, any
or all of the property not so removed and to apply the net proceeds of such
sale to the payment of any sum due hereunder, or to destroy such property.

                          ARTICLE XX
                          BROKERAGE

Each party warrants, and represents to the other, that it has not dealt with
any broker, other than Lynch, Murphy, Walsh & Partners and The Codman Company,
Inc.  in connection with the consummation  of this Lease, and each party shall
save harmless and indemnify the other party on account of loss, cost or
damage, which may arise by reason of such party's representation being untrue.

Landlord will be solely responsible for any compensation to Lynch, Murphy,
Walsh & Partners and The Codman Company in connection with this Lease.

                     ARTICLE XXI
                LANDLORD IMPROVEMENTS

Landlord shall, at its expense, perform the work described in Article I
hereof.  Landlord agrees to assign to Tenant any guarantees furnished to


                               11
<PAGE>
<PAGE>

Landlord by any contractor, or subcontractor, in connection with such work,
such assignment to be furnished at the commencement of the Lease Term.

Tenant agrees that Landlord may make any changes in such work, which may
become reasonably necessary or advisable, other than substantial changes,
without the prior approval of Tenant, provided notice thereof is promptly
given to Tenant, and Landlord may make substantial changes in such work, with
the prior written approval of Tenant.

Landlord covenants that (i) the demised premises shall be completed in a good
and workmanlike manner in accordance with the plans and specifications
referenced in Exhibit B hereto, and (ii) the demised premises and Building and
the means of access hereto shall be put in compliance with all applicable laws
and regulations, compliance with which is a condition precedent to the
Tenant's lawful occupancy of the demised premises.  The demised premises shall
be deemed to be Substantially Complete when the standards set forth in clauses
(i) and (ii) above are met, other than (with respect to clause (i)) completion
of items not reasonably necessary for the use of the demised premises for the
purpose for which it is leased hereunder, but the Landlord covenants to use
diligence to complete such items promptly an din any event no later than
thirty (30) days after the Commencement Date.

Landlord shall notify Tenant when Landlord's Improvements have advanced
sufficiently to permit Tenant to install its equipment and furnishings or to
perform any other work to be done by Tenant.  Entry by Tenant or its agents
for performing any other work shall be permitted by Landlord prior to the
commencement date of this Lease.

The cost of Landlord's Improvement as described in this section and the plans
and specifications attached hereto and marked Exhibit B, including without
limitation all labor and materials, electricity during the construction
period, building permits, charges of architects and engineers retained by
Landlord, and insurance relating to such work shall be paid by the Landlord,
or, if the Building is sold during construction, Landlord will provide to its
successor in interest to this Lease, funds sufficient to cover the costs of
Landlord's Improvements.

                     ARTICLE XXII
                MISCELLANEOUS PROVISIONS

22.1 OFFSET STATEMENTS.  Within five (5) days after receipt of Landlord's
written request therefore, Tenant shall execute and deliver to any mortgagee
of Landlord, present or future, and to any prospective purchaser of Landlord's
property, a statement acknowledging (if such be the case) that Landlord's
obligations hereunder have been fully performed to the date of such statement
(or, alternatively, specifying those matters as to which Tenant claims
Landlord is in default) and stating, also, the date, or dates, to which (or
the periods with respect to which) the payments required of Tenant hereunder
have been made and the then balance, according to Tenant's records, of any
Security Deposit held by Landlord hereunder.

22.2 WAIVER.  Tenant's failure to complain of any act or omission on the part
of the Landlord, or to complain of any deficiency in any payment or
performance tendered, (however long the same may continue), nor the payment or
acceptance of all or a part of the rent, nor the performance, either complete
or partial, of any other obligation, regardless of an accompanying
qualification at the time the payment of performance is tendered shall never
be deemed to waive, or to preclude, the exercise of any rights hereunder.  No
waiver, or any breach of any provision of this Lease, shall be deemed a waiver
of a breach of any other provision of this Lease, or a consent to any
subsequent occasion.  Each right and remedy under this Lease, or by operation


                             12
<PAGE>
<PAGE>

of law, shall be distinct and separate from every other right and remedy; all
such rights and remedies shall be cumulative, and none of them shall be deemed
inconsistent with, or exclusive of, any other, whether or not exercised; and
any two or more, or all such, rights and remedies may be exercised at the same
time, or successively.

22.3 "TENANT" DEFINED, SUCCESSORS.  The Term "Named Tenant", (as well as the
term "Tenant") and-the pronouns referring thereto, shall mean the party, or
parties, named originally in this Lease as such.  The term "Tenant" shall also
mean any assignee of the lessee interest in this Lease and party, or parties,
succeeding by operation of law to the interest of the Named Tenant and any
party, or parties, responsible for Tenant's obligations under this Lease.  If
there is more than one party named, or responsible, as Tenant, at any time,
the covenants of Tenant shall be joint and several obligations of each of the
partners and the obligations of the firm.

Except as expressly otherwise provided by any provisions of this Lease, the
terms and provisions of this Lease shall be binding upon and inure to the
benefit of the heirs, devisees, personal representatives, successors and
assigns, respectively, of the Landlord and Tenant.

22.4 LIMITATION OF LANDLORD'S LIABILITY.  If, at any time during the Term of
this Lease, the Landlord's interest hereunder shall be held by anyone acting
in a fiduciary capacity, then, notwithstanding any other provision of this
Lease, Landlord's obligations hereunder shall not be binding upon such
fiduciary individually, or upon any beneficiary or shareholder for whom such
fiduciary acts, but only upon such fiduciary in that capacity and upon the
trust estate.

The covenants of Landlord contained in this Lease shall be binding upon each
party holding the lessor interest herein only with respect to breaches
occurring during the time of that party's ownership of the Landlord's interest
hereunder.  In addition, Tenant specifically agrees to look solely to
Landlord's interest in the property of which the demised premises are a part
for the satisfaction of any claim or judgment against Landlord, it being
specifically agreed that neither Landlord, any partner, or other beneficial
owner of Landlord, nor anyone claiming under Landlord, shall ever be otherwise
liable for any such judgment.  In no event shall Landlord be liable for
indirect, or consequential, damages.

22.5 RULES AND REGULATIONS.  Tenant and its employees shall comply with all
rules and regulations promulgated by Landlord for the management of Building,
so long as the same shall be generally applicable to all occupants thereof. 
(Rules and Regulations, attached hereto as Exhibit C).

22.6 PRONOUNS.  Any pronoun shall be read in the singular, or plural, number,
and in such gender as the context may require.

22.7 HOLDING OVER.  If Tenant continues in occupancy of the demised premises
after the end of the Term, such occupancy shall be deemed a tenancy at
sufferance, terminable at Landlord's election, without notice to Tenant, or
anyone claiming under

Tenant, whether or not Landlord receives any payments for use and occupancy,
after the Term of this Lease ends, shall be calculated at the rate of one
hundred-fifty (150%) percent of the monthly rental for the last month of the
Leased Term, in addition to any other remedies of Landlord.

22.8 SEVERABILITY.  If any term, or provision, of this Lease, or the
application thereof to any person, or circumstance, shall, to any extent, be
invalid, or unenforceable, the remainder of this Lease, or the application of


                             13
<PAGE>
<PAGE>

such term, or provision, to persons, or circumstances, other than those as to
which it is held invalid, or unenforceable, shall not be affected thereby, and
each term and provision of this Lease shall be valid and be enforced to the
fullest extent permitted by law.


22.9 ENTIRE AGREEMENT.  The parties acknowledge and agree that, at all times,
they have intended that no preliminary agreements (either singly, or in
combination), oral statements, or representations, or prior written matter,
shall be binding on either party, or have any force, or effect, whatsoever,
and that they shall be bound to each other only by a single, formal,
comprehensive document containing all of the agreements of the parties, in
final form, which has been duly executed by Landlord, and by Tenant.

22.10 SIGNS.  Tenant shall not place, or erect, any sign on or about the
demised premises, or upon the outside of the Building, or which the demised
premises form a part, without the prior written consent of Landlord.

Landlord agrees to furnish and install building standard signage on the lobby
directory and tenant entry.

Landlord shall provide street signage identifying the Building and Landlord
may, at its sole discretion, provide Tenant signage on the street directory.

22.11 FORCE MAJEURE.  Whenever Landlord or Tenant shall be delayed in the
performance of any of its obligations hereunder, by reason of fire, strike,
labor difficulty, or other casualty, or other difficulties beyond Landlord's
control, the time for the performance of such obligations shall be extended
for the period of delay.

IN WITNESS WHEREOF, the parties hereto have executed this Lease, as of the
date first above written, to take effect as a sealed instrument.
