those whose first letters are capitalized) are defined in Exhibit E attached
hereto and, as used in this Agreement, they shall have the respective meanings
assigned or referred to in that exhibit.


2  Lease of the Leased Premises.

Premises, any of their respective employees, other agents and guests and such
other persons as the Landlord may, in the Landlord's sole discretion, determine

receipt of the Tenant's notice, the Landlord shall obtain, at the Tenant's
expense, a reputable, independent electrical engineer's formal written estimate

                                       14

authorized agent, upon one week's prior notice to the Landlord, may inspect the
Landlord's books and records, as they pertain to the particular expense in
question, at the Landlord's office regarding the subject of any such notice to
verify the amount(s) and calculations thereof.  After payment of its Tenant's
Share of the respective item for any period in accordance with the provisions of
section 10 of this Agreement, no further inspection or review shall be conducted
regarding Operational Expenses, Taxes, Capital Expenditures, Base Year
Operational Expenses or Base Year Taxes except with respect to items and periods
which may have been timely and otherwise properly questioned within the 45 day
period.  No inspection or review shall be conducted by any agent of the Tenant
engaged, in whole or in part, on a contingent fee basis; and if any inspection
or review is conducted, the Landlord shall have the right to verify that the
provisions of this prohibition have been satisfied in each instance.  The
Landlord shall cooperate in such review and inspection by making such records
reasonably available to the Tenant or its representatives.  In the event that as
a result of such inspection and review the parties agree that the Tenant has
paid to the Landlord an amount which is in excess of one hundred five (105%)
percent of the amount which Tenant should have paid pursuant to the notice given
by the Landlord in accordance with subsection 10.8 of this Agreement, the
Landlord shall credit the amount of the total overpayment against any amounts
next due from the Tenant under this Agreement, or in the event that there are no
longer any amounts due from the Tenant, the Landlord shall pay the amount of
such excess to the Tenant within thirty (30) days after the Landlord and the
Tenant agree to same.  In the event that as a result of such inspection and
review the parties agree that the Tenant has paid to the Landlord less than
ninety five (95%) percent of the amount Tenant should have paid pursuant to the
notice given by the Landlord in accordance with subsection 10.8 of this
Agreement, the Tenant shall pay to the Landlord the amount of the total
underpayment within thirty (30) days after the Landlord and Tenant agree to
same.  In the event that as a result of such inspection and review the parties
agree that the Tenant has paid to the Landlord, pursuant to the notice given by
the Landlord in accordance with subsection 10.8 of this Agreement, an amount
which is one hundred ten (110%) percent or more of the amount which Tenant
should have paid under subsection 10.8 of this Agreement, the Landlord shall pay
the Tenant's reasonable and actual costs of such inspection and review.  The
Tenant shall keep any information gained from such audit confidential and shall
not disclose it to any other party except the Tenant's retained professionals
and except in the context of any judicial or administrative proceedings
concerning Operational Expenses.  The exercise by the Tenant of its audit rights
hereunder shall not relieve the Tenant of its obligation to timely pay all sums
due hereunder, including, without limitation, any disputed Operational Expenses.
The provisions of this section shall survive the expiration or earlier
termination of this Agreement.

     10.12  The mere enumeration of an item within the definitions of
Operational Expenses and Capital Expenditures in subsections 10.2 and 10.3 of
this Agreement, respectively, shall not be deemed to create an obligation on the
part of the Landlord to provide such item unless the Landlord is affirmatively
required to provide such item elsewhere in this Agreement.

therefor and without such closing or interruption being deemed an eviction or
constructive eviction or requiring an abatement of Rent.  However, in
accomplishing any such work, the Landlord shall endeavor not to materially
interfere with the Tenant's use and enjoyment of the Leased Premises or the
conduct of the Tenant's business and to minimize interference, inconvenience and
annoyance to the Tenant.

     13.3  At all reasonable hours and upon reasonable prior notice for the
purpose of operating, inspecting or examining the Building, including the Leased
Premises, or the Property, provided that such entry shall not adversely affect
or interfere with the Tenant's business.

     13.4  At any time after the Tenant has vacated the Leased Premises, for the
purpose of preparing the Leased Premises for another tenant or prospective
tenant.

     13.5  If practicable by appointment with the Tenant, at all reasonable
hours for the purpose of showing the Building to prospective purchasers,
mortgagees and prospective mortgagees and prospective ground lessees and
lessors.

     13.6  If practicable by appointment with the Tenant, at all reasonable
hours during the last six months of the Term for the purpose of showing the
Leased Premises to prospective tenants thereof.

                                       18


     13.7  The mere enumeration of any right of the Landlord within this section
13 of the Agreement shall not be deemed to create an obligation on the part of
the Landlord to exercise any such right unless the Landlord is affirmatively
required to exercise such right elsewhere in this Agreement.

14  Liabilities and Insurance Obligations.
    --------------------------------------

     14.1  The Tenant shall, at the Tenant's own expense, purchase before the
Commencement Date, and maintain in full force and effect throughout the Term and
any other period during which the Tenant may have possession of the Leased
Premises, the following types of insurance coverage from financially sound and
reputable insurers, licensed by the State of New Jersey to provide such
insurance and acceptable to the Landlord, in the minimum amounts set forth
below, each of which insurance policies shall be for the benefit of, and shall
name the Landlord, the Landlord's managing agent and mortgagees and ground
lessors known to the Tenant, if any, of the Building, the Common Facilities, the
Property or any interest therein, their successors and assigns as additional
persons insured, and none of which insurance policies shall contain a "co-
insurance" clause:

           14.1.1  commercial general liability insurance and excess
("umbrella") insurance which, without limiting the generality of the foregoing,
considered together shall insure against such risks as bodily injury, personal
injury and property damage, with a combined single limit of not less than
$3,000,000.00 for each occurrence and in the aggregate (or such greater amounts
as the Landlord may reasonably specify from time to time by notice to the
Tenant);

           14.1.2  contractual liability insurance which shall insure the risk
of the Tenant's failure to perform all the Tenant's obligations under this
Agreement by which the Tenant indemnities the Landlord, in an amount not less
than $3,000,000.00; and

           14.1.3  "all risks" insurance covering the Leased Premises and
leasehold improvements thereto in an amount sufficient to cover the replacement
cost of all the Tenant's alterations, improvements, fixtures and personal
property located in or on the Leased Premises.

     14.2  With respect to risks:

           14.2.1  as to which this Agreement requires either party to maintain
insurance, or

           14.2.2  As to which either party is effectively insured and for which
risks the other party may be liable, the party required to maintain such
insurance and the party effectively insured shall use its best efforts to obtain
a clause, if available from the respective insurer, in each such insurance
policy expressly waiving any right of recovery, by reason of subrogation to such
party's rights or otherwise, the respective insurer might otherwise have or
obtain against the other party, so long as such a clause can be obtained in the
respective insurance policy without additional premium cost. If such a clause
can be obtained in the respective insurance policy, but only at additional
premium cost, such party shall, by notice to the other party, promptly advise
the other party of such fact and the amount of the additional premium cost. If
the other party

                                       19


desires the inclusion of such a clause in the notifying party's respective
insurance policy, the other party shall, within 10 days of receipt of the
notifying party's notice, by notice advise the notifying party of its desire and
enclose therewith its check in the full amount of the additional premium cost;
otherwise the notifying party need not obtain such a clause in the respective
insurance.

     14.3  Each party hereby waives any right of recovery against the other
party for any and all damages for property losses and property damages which are
actually insured by either party, but only to the extent:

           14.3.1  that the waiver set forth in this subsection 14.3 does not
cause or result in any cancellation of, or diminution in, the insurance coverage
otherwise available under any applicable insurance policy;

           14.3.2  of the proceeds of any applicable insurance policy (without
adjustment for any deductible amount set forth therein) actually received by
such party for such respective loss or damages; and

           14.3.3  the substance of the clause contemplated by subsection 14.2
of this Agreement is actually and effectively set forth in the respective
insurance policy.

The waiver set forth in this subsection 14.3 of the Agreement shall not apply
with respect to liability insurance policies (as opposed to property and
casualty insurance policies).

     14.4  The Tenant hereby waives any right of recovery it might otherwise
have against the Landlord for losses and damages caused actively or passively,
in whole or in part, by any of the risks the Tenant is required to insure
against in accordance with subsections 14.1.1 or 14.1.3 of this Agreement,
unless such waiver would cause or result in a cancellation of, or diminution in,
the coverage of the Tenant's policies of insurance against such risks.

     14.5  The Landlord shall have no liability whatsoever to the Tenant or the
Tenant's employees, other agents or Guests or anyone else for any death, bodily
injury, property loss or other damages suffered by any of them or any of their
property which is not caused by the negligence or intentional misconduct of the
Landlord.

     14.6  Each policy of insurance required under subsection 14.1 of this
Agreement shall include provisions to the effect that:

           14.6.1  no act or omission of the Tenant, its employees, other agents
or Guests shall result in a loss of insurance coverage otherwise available under
such policy to any person required to be named as an additional insured in
accordance with subsection 14.1 of this Agreement; and

           14.6.2  the insurance coverage afforded by such policy shall not be
diminished, cancelled, permitted to expire or otherwise terminated for any
reason except upon 30 days' prior

                                       20


written notice from the insurer to every person required to be named as an
additional insured in accordance with subsection 14.1 of this Agreement.

     14.7   At any time when the Tenant or its contractors may be building out
the Leased Premises or altering or improving any part of the Building at the
Tenant's instance, the Tenant shall, at the Tenant's own expense, purchase
before commencing such work, and maintain in full force and effect until final
completion of the respective work, builders' risk insurance coverage from
financially sound and reputable insurers, licensed by the State of New Jersey to
provide such insurance and acceptable to the Landlord, which provides
replacement cost coverage in the event any of the work is damaged by a covered
peril as defined in the policy, which insurance policy shall be for the benefit
of, and shall name, the Landlord, the Landlord's managing agent and mortgagees
and ground lessors known to the Tenant, if any, of the Building, the Common
Facilities, the Property or any interest therein, their successors and assigns
as additional persons insured, and none of which insurance policies shall
contain a "co-insurance" clause.

     14.8   With respect to each type of insurance coverage referred to in
subsection 14.1 of this Agreement, prior to the Commencement Date the Tenant
shall cause its insurer(s) to deliver to the Landlord the certificates) of the
insurer(s) setting forth the name and address of the insurer, the name and
address of each additional insured, the type of coverage provided, the limits of
the coverage, the effective dates of coverage and that each policy under which
coverage is provided affirmatively includes provisions to the effect set forth
in subsection 14.6 of this Agreement.  In the event any of such certificates
indicates a coverage termination date earlier than the end of the Term or the
end of any other period during which the Tenant may have possession of the
Leased Premises, no later than 10 days before any such coverage termination
date, the Tenant shall deliver to the Landlord respective, equivalent, new
certificates) of the insurer(s).

     14.9   Throughout the Term, the Landlord shall insure the Building against
loss due to fire and other casualties covered in standard extended coverage
insurance policies in an amount equal to at least 100% of the replacement cost
thereof, exclusive of architectural and engineering fees and excavation,
footings and foundations costs.  Such insurance shall also cover any initial
leasehold improvements constructed or installed in the Leased Premises, as may
be contemplated by section 5 of this Agreement, but shall not cover the Tenant's
furniture, fixtures, equipment or other personal property of the Tenant in the
Leased Premises.  Throughout the Term, the Landlord shall maintain comprehensive
general public liability insurance and excess ("umbrella") insurance which,
without limiting the generality of the foregoing, considered together shall
insure against such risks as bodily injury, death and property damage with a
combined single limit of not less than $3,000,000 for each occurrence and in the
aggregate.

     14.10  The Landlord hereby waives any right of recovery it might otherwise
have against the Tenant for losses and damages caused actively or passively, in
whole or in part, by any of the risks the Landlord is required to insure against
in accordance with this Agreement, unless such waiver would cause or result in a
cancellation of, or diminution in, the coverage of the Landlord's policies of
insurance against such risks.

15  Casualty Damage to Building or Leased Premises.
    ----------------------------------------------

                                       21


     15.1  In the event of any damage to the Building or any portion thereof by
fire or other casualty, with the result that the Leased Premises are rendered
unusable, in whole or in part, or not reasonably accessible to and from the
Building's Common Facilities, within 30 business days of the occurrence of the
casualty the Landlord shall determine and give notice of its determination to
the Tenant whether, due to the extent of damage and the Landlord's analysis of
the economic feasibility of rebuilding or restoring, the Landlord intends not to
rebuild or restore the Building or, if the Landlord shall not have made that
determination, the Landlord's reasonable opinion of the period of time required
to restore the Building and the Leased Premises to their condition immediately
prior to the occurrence of the respective casualty (exclusive of any
improvements constructed, installed or added in the Leased Premises as
contemplated by sections 5 or 12 of this Agreement).

           15.1.1  If the Landlord gives timely notice of its determination that
it does not intend to rebuild or restore, due to the extent of damage and the
Landlord's analysis of the economic feasibility of rebuilding or restoring, then
this Agreement and the Term shall terminate effective as of the date of the
subject casualty with respect to those portions of the Leased Premises rendered
unusable by the subject casualty and as of the date of the Tenant's surrender
with respect to those portions of the Leased Premises which were not rendered
unusable by the subject casualty.

           15.1.2  Otherwise, if, in Landlord's reasonable opinion, the
restoration contemplated by subsection 15.1 of this Agreement will take more
than 240 days (inclusive of a reasonable period for adjustment of the Landlord's
insurance claim, but exclusive of any period for resort to a formal dispute
resolution forum with the insurer), then either the Landlord or the Tenant may
elect to terminate the Term and this Agreement (effective as of the date of the
subject casualty with respect to those portions of the Leased Premises rendered
unusable by the subject casualty and as of the date of the Tenant's giving
notice with respect to those portions of the Leased Premises which were not
rendered unusable by the subject casualty) by timely notice of its election to
the other.  Notice of the Landlord's election to terminate, if any, shall be
given to the Tenant within the 30 business day period contemplated by subsection
15.1 of this Agreement.  If the Landlord shall not timely elect to terminate the
Term and this Agreement, notice of the Tenant's election to terminate, if any,
shall be given to the Landlord within the 30 day period immediately succeeding
the Landlord's giving notice to the Tenant of the Landlord's estimated period to
rebuild or restore.

           15.1.3  If (a) in the Landlord's reasonable opinion, the restoration
contemplated by subsection 15.1 of this Agreement will take more than 240 days
(inclusive of a reasonable period for adjustment of the Landlord's insurance
claim, but exclusive of any period for resort to a formal dispute resolution
forum with the insurer) and neither the Landlord nor the Tenant shall have
timely exercised their respective rights to terminate contemplated by subsection
15.1.2 of this Agreement or (b) in the Landlord's reasonable opinion, the
restoration contemplated by subsection 15.1 of this Agreement will take 240 days
or less (inclusive of a reasonable period for adjustment of the Landlord's
insurance claim, but exclusive of any period for resort to a formal dispute
resolution forum with the insurer), then this Agreement shall remain in effect
and the

                                       22


Landlord shall restore the Building and the Leased Premises as contemplated by
subsection 15.1 of this Agreement to the extent the Landlord shall have received
(and no mortgagee of the Property or the Building shall have received) proceeds
of any property, casualty or liability insurance on the damaged portions,
causing the restoration to proceed diligently and expediently. Under the
circumstances contemplated by clause (b) of this subsection 15.1.3 of the
Agreement, if the Landlord shall not have timely restored the Building and the
Leased Premises as contemplated by subsection 15.1 of this Agreement to the
extent the Landlord shall have received proceeds of any property or liability
insurance on the damaged portions, the Term shall terminate upon the expiration
of 90 additional days (without the Landlord's completion of its restoration
obligation in the interim) after the Tenant shall have given prompt notice that
the Landlord has not completed its restoration obligations on a timely basis and
that the Tenant desires termination of the Term (which termination shall be
effective as of the date of the subject casualty with respect to those portions
of the Leased Premises rendered unusable by the subject casualty and as of the
date of the Tenant's giving notice with respect to those portions of the Leased
Premises which were not rendered unusable by the subject casualty).

     15.2  Under the circumstances contemplated by subsection 15.1 of this
Agreement, Rent shall abate from the date of the casualty until such time as the
Building and the Leased Premises are again restored by the Landlord as
contemplated by subsection 15.1 of this Agreement by the amount which bears the
same proportion to the Rent otherwise payable during such period as the gross
rentable floor space of the Leased Premises which are rendered unusable or not
reasonably accessible to and from the Common Facilities of the Building bears to
the gross rentable floor space of the Leased Premises.

     15.3  The restoration of the improvements constructed or installed in the
Leased Premises as contemplated by sections 5 or 12 of this Agreement shall be
the Tenant's responsibility.  The Tenant shall make reasonable, good faith
efforts to integrate the restoration which is its responsibility with the
restoration which is the Landlord's responsibility.  To the extent such
integration is not feasible, the Tenant shall be allowed an additional,
reasonable interval to complete its work, not to exceed 30 days after the
completion of the Landlord's restoration work, and Rent shall continue to abate
until the earlier of (i) the expiration of such additional interval or (ii) the
completion of the Tenant's work, to the same extent contemplated by subsection
15.2.  The Landlord shall cooperate with Tenant to integrate the restoration of
such improvements during the reconstruction period.

     15.4  In the event either the Landlord shall make any election to cancel
contemplated by subsection 15.1.1 of this Agreement or either the Landlord or
the Tenant shall make any election to cancel contemplated by subsection 15.1.2
of this Agreement and this Agreement has in fact been terminated, then the
Landlord may proceed with restoration (or non-restoration) in any manner it
chooses, without any liability to Tenant.

     15.5  The Tenant shall promptly advise the Landlord by the quickest means
of communication of the occurrence of any casualty damage to the Building or the
Leased Premises of which the Tenant becomes aware.

                                       23


16  Condemnation.
    ------------

     16.1  This section 16 of the Agreement shall apply if the power of eminent
domain (or private purchase by any public or quasi-public body in lieu thereof
for any public or quasi-public purpose) shall be exercised with the result that:

           16.1.1  all or substantially all the Property or the Leased Premises
is taken during the Term for at least the balance of the Term;

           16.1.2  less than substantially all the Property, the Building or the
Common Facilities (but none of the Leased Premises) is taken during the Term for
at least the balance of the Term, but the Landlord reasonably promptly
determines in good faith that it is not economically feasible for the Landlord
to make any necessary alterations and continue to operate the portions not so
taken, as they may be altered, as a first class Building and facility in the
vicinity for the balance of the Term;

           16.1.3  less than substantially all the Leased Premises is taken
during the Term for at least the balance of the Term, but the Tenant reasonably
promptly determines in good faith that it can not continue to use and enjoy the
portions not so taken for the conduct of its business in the ordinary course
during the balance of the Term; or

           16.1.4  so much of the Property or the Common Facilities is taken
during the Term for at least the balance of the Term that the Leased Premises
are not reasonably accessible to and from the Common Facilities and reasonable
alternate access is not provided by the Landlord.

     16.2  Under the circumstances contemplated by subsections 16.1.1 and
subsections 16.1.4 of this Agreement, then either the Landlord or the Tenant may
elect to terminate the Term by notice to the other given within 30 days after,
and effective as of, the later of the date (i) that the condemnor acquires title
to the portions taken or (ii) that possession of the portions taken is required
to be delivered or surrendered to the condemning authority.  Under the
circumstances contemplated by subsection 16.1.2 of this Agreement the Landlord,
and under the circumstances contemplated by subsection 16.1.3 of this Agreement
the Tenant, respectively, may elect to terminate the Term by notice to the other
given within 30 days after, and effective as of, the later of the date (i) that
the condemnor acquires title to the portions taken or (ii) that possession of
the portions taken is required to be delivered or surrendered to the condemning
authority.

     16.3  Under the circumstances contemplated by subsection 16.1 of this
Agreement, if no party with any right to elect to terminate the Term under
subsection 16.2 of this Agreement shall have given timely notice to the other of
exercise of its election to terminate the Term, this Agreement shall continue in
full force and effect, but Rent shall abate, effective as of the later of the
date (i) that the condemnor acquires title to the portions taken or (ii) that
possession of the portions taken is required to be delivered or surrendered to
the condemning authority, by the amount which bears the same proportion to the
Rent otherwise payable during any period as the

                                       24


gross rentable floor space, if any, of the Leased Premises which is taken bears
to the gross rentable floor space of the Leased Premises.

     16.4  Under any of the circumstances contemplated by this section 16 of the
Agreement, the Tenant hereby waives any claim against the Landlord, the
condemning authority for any thing of value, tangible or intangible, including,
without limiting the generality of the foregoing, the putative value of any
leasehold interest or the loss of the use of same, except for any right the
Tenant might have to make a claim, independent of, and without reference to or
having any effect on, any claim, award or settlement of the Landlord, against
the condemning authority regarding the value of the Tenant's installed trade
fixtures and other installed equipment which are not removable from the Leased
Premises or for ordinary and necessary moving and relocation expenses occasioned
by the taking.

17  Assignment or Subletting by Tenant.
    ----------------------------------

     17.1  Except as may be specifically set forth in this section 17 of the
Agreement, the Tenant shall not:

           17.1.1  assign, or purport to assign, this Agreement or any of the
Tenant's rights hereunder;

           17.1.2  sublet, or purport to sublet, the Leased Premises or any

           17.1.3  license, or purport to license, the use or occupancy of the
Leased Premises or any portion thereof;

           17.1.4  otherwise transfer, or attempt to transfer any interest

use and occupancy of the Leased Premises; or

           17.1.5  indirectly accomplish, or permit or suffer the accomplishment
of, any of the foregoing by merger or consolidation with another entity, by
acquisition or disposition of assets or liabilities outside the ordinary course
of the Tenant's business or by acquisition or disposition, by the Tenant's
equity owners or subordinated creditors, of any of their respective interests in
the Tenant.

     17.2  The Tenant shall not assign this Agreement or any of the Tenant's
rights hereunder or sublet the Leased Premises or any portion thereof without
first giving sixty days' prior notice to the Landlord of its desire to assign or
sublet and requesting the Landlord's consent and without first receiving the
Landlord's prior written consent, which consent shall not be unreasonably,
withheld, delayed or conditioned.  The Tenant's notice to the Landlord shall
include:

           17.2.1  the full name, address and telephone number of the proposed
assignee or sublessee;

the proposed assignment or sublease including, without limiting the generality
of the foregoing, all consideration paid or given, or proposed to be paid or to
be given, by the proposed assignee, sublessee or other person to the Tenant and
the respective times of payment or delivery; and

           17.2.7  any other information reasonably requested by the Landlord.

     17.3  By the expiration of the notice period contemplated by subsection
17.2 of this Agreement, the Landlord, in its sole discretion, shall take one of
the following actions by notice to the Tenant:

           17.3.1  grant consent on the terms and conditions set forth in
subsection 17.4 of this Agreement and such other reasonable terms and conditions
set forth in the Landlord's notice;

           17.3.2  refuse to grant consent for any of the reasons set forth in
subsection 17.5 of this Agreement or for any other reasonable reason set forth
in the Landlord's notice; or

           17.3.3  elect to terminate the Term as of (a) the end of the third
full month after the Tenant has given notice of the Tenant's desire to assign or

     17.4  The Landlord's consent to the Tenant's proposed assignment or
sublease, if granted under subsection 17.3.1 of this Agreement, shall be subject
to all the following terms and conditions (and to any other terms and conditions
permitted by that subsection):

           17.4.1  any proposed assignee or sublessee shall, by document
executed and delivered forthwith to the Landlord, agree to be bound by all the
obligations of the Tenant set forth in this Agreement;

                                       26


           17.4.2  the Tenant shall remain liable under this Agreement, jointly

value of any other thing of value within 10 days of receipt of same; and

           17.4.5  with respect to any amount payable to the Tenant in equal

amount of the balance of unrecovered Transaction Costs in connection with the
respective assignment or sublet, amortized over the term of the respective
assignment or sublet), which amount is in excess of the amount which bears the
same ratio to the monthly installment of Rent due from the Tenant as the usable
floor space of the Leased Premises subject to the assignment or sublease bears
to the usable floor space of the entire Leased Premises, the Tenant shall pay
one-half of such excess to the Landlord together with the Tenant's monthly
installment of Rent.

     17.5  The Landlord's refusal to grant consent under subsection 17.3.2 of
this Agreement shall not be deemed an unreasonable withholding of consent if
based upon any of the following reasons (or any other reason permitted by that
subsection):

the Term;

           17.5.5  less than one year remains in the Term as of the proposed
effective date of the proposed assignment or sublease;

                                       27


           17.5.6  the general reputation, financial position or ability or type
of business of, or the anticipated use of the Leased Premises by, the proposed
assignee or proposed sublessee is unsatisfactory to the Landlord or is
inconsistent with those of tenants of Other Leased Premises or of the Carnegie
Center Complex or inconsistent with any commitment made by the Landlord to any
such other tenant;

           17.5.7  the proposed consideration to be paid to the Tenant during
any period of 12 months is less than ninety five (95%) percent of the amount of
the Market Rental Rate divided by the gross rentable floor space of the Leased
Premises and multiplied by that portion of the gross rentable floor space of the
Leased Premises proposed to be subject to the proposed assignment or sublease;

           17.5.8  the gross rentable floor space of the portion of the Leased
Premises proposed to be sublet is less than one-third of the gross rentable
floor space of the Leased Premises; or

           17.5.9  the proposed assignee or sublessee is a tenant of Other
Leased Premises; or

           17.5.10 the proposed assignee or sublessee is a tenant of other

election, and the effective date thereof, to the Tenant and to receive Re-
Leasing Damages;

           23.1.3  if the Tenant remains in possession of the Leased Premises
after the Tenant's obligation to surrender the Leased Premises shall have
arisen, to remove the Tenant and

the Tenant's and any others' possessions from the Leased Premises by any of the
following means without any liability to the Tenant therefor, any such liability
to the Tenant therefor which might otherwise arise being hereby waived by the
Tenant: legal proceedings (summary or otherwise), writ of dispossession and any
other means and to receive Holdover Damages and, except in the circumstances
contemplated by section 20 of this Agreement, to receive all expenses incurred
in removing the Tenant and the Tenant's and any others' possessions from the
Leased Premises, and of storing such possessions if the Landlord so elects;

           23.1.4  to seek specific performance, temporary restraints and
preliminary and permanent injunctive relief regarding Events of Default where
the Landlord's rights and remedies at law may be inadequate, without the
necessity of proving actual damages or the inadequacy of the rights and remedies
at law;

           23.1.5  to receive all expenses incurred in securing, preserving,
maintaining and operating the Leased Premises during any period of vacancy, in
making repairs to the Leased Premises, in preparing the Leased Premises for re-

generality of the foregoing, any brokerage commissions;

           23.1.6  to receive all legal expenses, including without limiting the
generality of the foregoing, reasonable attorneys' fees incurred in connection
with pursuing any of the Landlord's rights and remedies, including
indemnification rights and remedies;

           23.1.7  if the Landlord, in its sole discretion, elects to perform
any obligation of the Tenant under this Agreement (other than the obligation to
pay Rent) which the Tenant has not timely performed, to receive all expenses

           23.1.8  to elect to pursue any legal or equitable right and remedy

any of the rights and remedies set forth in subsection 23.1 of this Agreement.

     23.2  In the event the Landlord elects the right and remedy set forth in
subsection 23.1.1 of this Agreement, Termination Damages shall be equal to the
amount which, at the time of actual payment thereof to the Landlord, is the sum
of:

           23.2.1  all accrued but unpaid Rent;

           23.2.2  the present value (calculated using the most recently
available (at the time of calculation) published weekly average yield on United
States Treasury securities having maturities comparable to the balance of the
then remaining Term) of the sum of all payments of Rent remaining due (at the
time of calculation) until the date the Term would have expired (had there been
no election to terminate it earlier) less the present value (similarly
calculated) of all payments of rent to be received through the end of the Term
(had there been no election to terminate it earlier) from a lessee, if any, of
the Leased Premises at the time of calculation (and it

                                       32


shall be assumed for purposes of such calculations that (i) the amount of future
Additional Rent due per year under this Agreement will be equal to the average
Additional Rent per month due during the 12 full calendar months immediately
preceding the date of any such calculation, increasing annually at a rate of
eight percent compounded, (ii) if any calculation is made before the first
anniversary of the end of the No Pass Through Period, the average Additional
Rent due for any month after the end of the No Pass Through Period will be equal
to nine percent of the sum of the Base Year Operating Expenses, Base Year Taxes,
Annual Amortized Capital Expenditures and Tenant Electric Charges (considered on
an annual basis), (iii) if any calculation is made before the beginning of the
Base Year, the sum of Base Year Taxes and Base Year Operational Expenses shall
be assumed to be $5.00 per gross rentable square foot and (iv) if any
calculation is made before the end of the Base Year, Base Year Taxes and Base
Year Operational Expenses may be extrapolated based on the year to date
experience of the Landlord);

           23.2.3  the Landlord's reasonably estimated cost of demolishing any
leasehold improvements to the Leased Premises; and

           23.2.4  that amount, which as of the occurrence of the Event of
Default, bears the same ratio to the costs, if any, incurred by the Landlord
(and not paid by the Tenant) in building out the Leased Premises in accordance
with section 5 of this Agreement as the number of months remaining in the Term
(immediately before the occurrence of the Event of Default) bears to the number
of months in the entire Term (immediately before the occurrence of the Event of
Default).

     23.3  In the event the Landlord elects the right and remedy set forth in
subsection 23.1.2 of this Agreement, Re-Leasing Damages shall be equal to the
Rent less any rent actually and timely received by the Landlord from any lessee
of the Leased Premises or any portion thereof, payable at the respective times
that Rent is payable under the Agreement plus the cost, if any, to the Landlord
of building out or otherwise preparing the Leased Premises for, and leasing the
Leased Premises to, any such lessee.

     23.4  In the event the Landlord elects the right and remedy set forth in
subsection 23.1.3 of this Agreement, Holdover Damages shall mean damages at the
rate per month or part thereof equal to the greater of:  (a) one and one-half
times one-twelfth of the then Market Rental Rate plus all Additional Rent as set
forth in this Agreement or (b) double the average amount of all payments of Rent
due under this Agreement during each of the last 12 full calendar months prior
to the Landlord's so electing or, in the event the Term shall have terminated by
expiration under subsection 24.1.1 of this Agreement, the last full 12 calendar
months of the Term, in either case payable in full on the first day of each
holdover month or part thereof.

     23.5  In connection with any summary proceeding to dispossess and remove
the Tenant from the Leased Premises under subsection 23.1.3 of this Agreement,
the Tenant hereby waives:

           23.5.1  any notices for delivery of possession thereof, of
termination, of demand for removal therefrom, of the cause therefor, to cease,
to quit and all other notices that might otherwise be required pursuant to 2A
N.J.S.A. 18-53 et seq.;
               ------

                                       33


           23.5.2  any right the Tenant might otherwise have to cause a
termination of the action or proceeding by paying to the Landlord or into court
or otherwise any Rent in arrears;

           23.5.3  any right the Tenant might otherwise have to a period of
waiting between issuance of any warrant in execution of any judgment for
possession obtained by the Landlord and the execution thereof;

           23.5.4  any right the Tenant might otherwise have to transfer or
remove such proceeding from the court (or the particular division or part of the
court) or other forum in which it shall have been instituted by the Landlord to
another court, division or part;

           23.5.5  any right the Tenant might otherwise have to redeem the
Tenant's former leasehold interest between the entry of any judgment and the
execution of any warrant issued in connection therewith by paying to the
Landlord or into Court or otherwise any Rent in arrears; and

           23.5.6  any right the Tenant might otherwise have to appeal any
judgment awarding possession of the Leased Premises to the Landlord.

     23.6  The enumeration of rights and remedies in this section 23 of the
Agreement is not intended to be exhaustive or exclusive of any rights and
remedies which might otherwise be available to the Landlord, or to force an
election of one or more rights and remedies to the exclusion of others,
concurrently, consecutively or sequentially.  On the contrary, each right and
remedy enumerated in this section 23 of the Agreement is intended to be
cumulative with each other right and remedy enumerated in this section 23 of the
Agreement and with each other right and remedy that might otherwise be available
to the Landlord; and the selection of one or more of such rights and remedies at
any time shall not be deemed to prevent resort to one or more others of such
rights and remedies at the same time or a subsequent time, even with regard to
the same occurrence sought to be remedied.

     23.7  The Landlord shall use reasonable efforts to mitigate damages.

24  Termination of the Term.
    -----------------------

     24.1  The Term shall terminate upon the earliest of the following events to
occur:

           24.1.2  in connection with a transaction contemplated by section 16
of this Agreement and under the circumstances contemplated by subsection 16.2 of
this Agreement, the effective date of termination of the Term as set forth in
subsection 16.2;

                                       34


           24.1.3  upon the respective effective dates of termination set forth
in the various subsections (whichever may be applicable) of subsection 15.1 of
this Agreement providing for termination of the Term under various
circumstances; or

           24.1.4  the effective date of any election by the Landlord under
subsection 17.3.3 of this Agreement in response to the Tenant's notice of the
Tenant's desire to assign this Agreement or to sublet all or a portion of the
Leased Premises; or

           24.1.5  the effective date of any election by the Landlord to
terminate the Term under subsection 23.1.1 of this Agreement.

     24.2  No termination of the Term shall have the effect of releasing the
Tenant from any obligation or liability theretofore or thereby incurred and,
until the Tenant shall have surrendered the Leased Premises in accordance with
section 21 of this Agreement, from any obligation or liability thereafter
incurred.

25  Mortgage and Underlying Lease Priority.  This Agreement and the estate,
    --------------------------------------
interest and rights hereby created for the benefit of the Tenant are, and shall
always be, subject and subordinate to the lien, terms and provisions of any
mortgage (other than a mortgage created by the Tenant or a sale, transfer or
other disposition by the Tenant in the nature of a security interest in
violation of subsections 17.1.4 and 22.5, respectively, of this Agreement)
already or afterwards placed on the Carnegie Center Complex, the Property, the
Common Facilities, the Building or any estate or interest therein including,
without limiting the generality of the foregoing, any new mortgage or any
mortgage extension, renewal, modification, consolidation, replacement,
supplement or substitution.  This Agreement and the estate, interest and rights
hereby created for the benefit of the Tenant are, and shall always be,
subordinate to any ground lease already or afterwards made with regard to the
Carnegie Center Complex, the Property, the Common Facilities, the Building or
any estate or interest therein including, without limiting the generality of the
foregoing, any new ground lease or any ground lease extension, renewal,
modification, consolidation, replacement, supplement or substitution.  The
provisions of this section 25 of the Agreement shall be self-effecting; and no
further instrument shall be necessary to effect any such subordination.
However, in confirmation of either of the foregoing subordinations, the Tenant
shall, at the Landlord's written request, execute any requisite or appropriate
certificate or other document.  If the Tenant does not execute and deliver any
requisite or appropriate certificate or other document within 10 days of the
Landlord's written request therefor, the Tenant hereby constitutes and appoints
the Landlord as the Tenant's attorney in fact to execute any such certificate or
other document for or on behalf of the Tenant.  Nevertheless, the Tenant hereby
consents that any mortgagee or mortgagee's successor in interest may, at any
time and from time to time, by notice to the Tenant, subordinate its mortgage to
the estate and interest created by this Agreement; and upon the giving of such
notice, the subject mortgage shall be deemed subordinate to the estate and
interest created by this Agreement regardless of the respective times of
execution or delivery of either or of recording the subject mortgage.

26  Transfer by Landlord.
    --------------------

                                       35


     26.1  The Landlord shall have the right at any time and from time to time
to sell, transfer, lease or otherwise dispose of the Carnegie Center Complex,
the Property, the Common Facilities or the Building or any of the Landlord's
interests therein, or to assign this Agreement or any of the Landlord's rights
thereunder.

     26.2  Upon giving notice of the occurrence of any transaction contemplated
by subsection 26.1 of this Agreement, the Landlord shall thereby be relieved of
any obligation that might otherwise exist under this Agreement with respect to
periods subsequent to the effective date of any such transaction.  If, in
connection with any transaction contemplated by subsection 26.1 of this
Agreement the Landlord transfers, or makes allowance for, any Security Deposit
of the Tenant and gives notice of that fact to the Tenant, the Landlord shall
thereby be relieved of any further obligation to the Tenant with regard to any
such Security Deposit; and the Tenant shall look solely to the transferee with
respect to any such Security Deposit.

     26.3  In the event of the occurrence of any transaction contemplated by
subsection 26.1 of this Agreement the Tenant, upon written request therefor from
the transferee, shall attorn to and become the tenant of such transferee upon
the terms and conditions set forth in this Agreement.

     26.4  Notwithstanding anything to the contrary that may be set forth in
subsections 26.1, 26.2 and 26.3 of this Agreement, in the event any mortgage
contemplated by section 25 of this Agreement is enforced by the respective
mortgagee pursuant to remedies provided in the mortgage or otherwise provided by
law or equity and any person succeeds to the interest of the Landlord as a
result of, or in connection with, any such enforcement, the Tenant shall, upon
the request of such successor in interest, automatically attorn to and become
the Tenant of such successor in interest without any change in the terms or
provisions of this Agreement, except that such successor in interest shall not
be bound by:  (a) any payment of Basic Rent or Additional Rent (exclusive of
prepayments in the nature of a Security Deposit actually received by such
successor) for more than one month in advance or (b) any amendment or other
modification of this Agreement which was made without the consent of such
mortgagee or such successor in interest; and, upon the request of such successor
in interest, the Tenant shall execute, acknowledge and deliver any instruments)
confirming such attornment.  Furthermore, the Tenant agrees that on such
attornment, such successor shall not be (i)liable for damages for any act or
omission of any prior landlord or (ii) be subject to any credits, offsets,
defenses, claims or counterclaims that the Tenant might have against any prior
landlord for periods prior to such attornment.  The Tenant waives the provisions
of any statute or rule of law, now or hereafter in effect, which may give or
purport to give the Tenant any right to terminate or otherwise adversely affect
this Agreement and the obligations of the Tenant hereunder in the event of the
enforcement of any mortgage as set forth above.  In all events, within-10 days
of the written request of the Landlord, the Tenant shall execute and deliver to
the Landlord a subordination, non-disturbance and attornment agreement in the
then current standard form of any mortgagee of the Property or any portion
thereof, provided such standard form does not purport to increase the Tenant's
obligations under this Agreement or to diminish the Tenant's rights under this
Agreement.

                                       36


     26.5  If this Agreement and the estate, interest and rights hereby created
for the benefit of the Tenant are ever subject and subordinate to any ground
lease contemplated by section 25 of this Agreement:

           26.5.1  upon the expiration or earlier termination of the term of any
such ground lease before the termination of the Term under this Agreement, the
Tenant shall attorn to, and become the Tenant of, the lessor under any such
ground lease and recognize such lessor as the Landlord under this Agreement for
the balance of the Term; and

           26.5.2  such expiration or earlier termination of the term of any
such ground lease shall have no effect on the Term under this Agreement.

     26.6  Notwithstanding anything to the contrary that may be set forth in
section 25 of this Agreement, with respect to any mortgages or ground leases
contemplated by section 25 of this Agreement, the Landlord shall use reasonable
commercial efforts to obtain from each such mortgagee and ground lessor its
respective standard form of non-disturbance, attornment and subordination
agreement which includes a provision to the effect that, in the event of
enforcement of any remedies provided in the respective mortgage or ground lease,
respectively, or otherwise, so long as an Event of Default shall not have
occurred, the Tenant shall not be disturbed in its possession of the Leased
Premises in accordance with this Agreement and which does not include any
provision increasing the Tenant's obligations otherwise due, or diminishing the
Tenant's rights otherwise available, in either case in accordance with this
Agreement.  Any processing or other fee that the mortgagee or ground lessor may
charge and any reasonable legal expense that the Landlord may incur in
connection with performing its obligations under this subsection shall be paid
by the Tenant.

     26.7  No part of the Rent payable under this Agreement, if any, shall be
based in whole or in part on the income or profits derived from the Leased
Premises except for percentage rent based on gross (not net) receipts or sales.
If the mortgagee providing financing of all or any part of the Property succeeds
to the Landlord's interest under this Agreement and such mortgagee's counsel
advises the Landlord in writing that all or any portion or the Rent payable
under this Agreement is or may be deemed to be unrelated business income within
the meaning of the Internal Revenue Code or regulations issued thereunder, such
mortgagee may elect to amend unilaterally the calculation of the Rent under this
Agreement will constitute unrelated business income, but such amendment shall
not increase the Tenant's payment obligations or other liability under this
Agreement or reduce the Landlord's obligations under this Agreement.  If such
mortgagee so request in writing, the Tenant shall be obligated to execute any
document the mortgagee deems necessary to effect such amendment of this
Agreement.  Any sublease of the Leased Premises or any portion thereof shall
include the provisions of this subsection 26.7.

27  Indemnification.
    ---------------

     27.1  The Tenant shall, and hereby does, indemnify the Landlord against any
and all liabilities, obligations, damages, penalties, claims, costs, charges and
expenses including, without limiting the generality of the foregoing, expenses
of investigation, defense and enforcement

                                       37


thereof or of the obligation set forth in this section 27 of the Agreement
including, without limiting the generality of the foregoing, attorneys' fees,
imposed on or incurred by the Landlord in connection with any of the following
matters which occurs during the Term:

           27.1.1  any matter, cause or thing arising out of the use, occupancy,
control or management of the Leased Premises or any portion thereof which is not
caused by the Landlord's negligence or intentional act;

           27.1.2  any negligence or intentional act on the part of the Tenant
or any of its employees, other agents or Guests;

           27.1.3  any accident, injury or damage to any person or property
occurring in or about the Leased Premises which is not caused by the Landlord's
active gross negligence or intentional act;

           27.1.4  any representation made by the Tenant in this Agreement shall
have been inaccurate or incomplete in any material respect either on the date it
was made or the date as of which it was made;

           27.1.5  the imposition of any mechanic's, materialman's or other lien
on the Property, the Common Facilities, the Building, the Leased Premises or any
portion of any of the foregoing, or the filing of any notice of intention to
obtain any such lien, in connection with any alteration, improvement or other
modification of the Leased Premises made or authorized by the Tenant (which
indemnification obligation shall be deemed to include the Tenant's obligations
set forth in subsection 12.2.4.3 of this Agreement); or

           27.1.6  any failure on the part of the Tenant to perform or comply
with any obligation of the Tenant set forth in this Agreement.  Notwithstanding

participate therein and, to the extent it may desire, assume the defense thereof
through independent counsel selected by the Tenant and reasonably satisfactory
to the Landlord.  The Landlord shall not be bound by any compromise or
settlement of any such claim, action or proceeding without its prior written
consent.

28  Parties' Liability.
    -------------------

                                       38


     28.1  None of the following occurrences shall constitute a breach of this
Agreement by the Landlord, a termination of the Term, an active or constructive
eviction or an occurrence requiring an abatement of Rent:

           28.1.1  the inability of the Landlord to provide any utility or
service to be provided by the Landlord, as described in section 8 of this
Agreement which is due to causes beyond the Landlord's control, or to necessary
or advisable improvements, maintenance, repairs or emergency, so long as the
Landlord uses reasonable efforts and diligence under the circumstances to
restore the interrupted service or utility;

           28.1.2  any improvement, modification, alteration or other change
made to the Carnegie Center Complex, the Property, the Building or the Common
Facilities by the Landlord consistently with the Landlord's obligations set
forth in subsection 13.2 of this Agreement; and

           28.1.3  any change in any Federal, state or local law or ordinance.

     28.2  Except for the commencement, duration or termination of the Term
(other than under the circumstances contemplated by subsection 15.1 of this
Agreement), the Tenant's obligation to make timely payments of Rent, the
Tenant's obligation to maintain certain insurance coverage in effect, the
Tenant's failure to perform any of its other obligations under this Agreement if
such failure has caused loss or damage that can not promptly be cured by
subsequent act of the Tenant and the period within which any type of option or
optional right exercisable by the Tenant must be exercised, any period of time
during which the Landlord or the Tenant is prevented from performing any of its
respective obligations under this Agreement because of fire, any other casualty
or catastrophe, strikes, lockouts, civil commotion, acts of God or the public
enemy, governmental prohibitions or preemptions, embargoes or inability to
obtain labor or material due to shortage, governmental regulation or prohibition
or any other cause beyond the Landlord's control, shall be added to the time
when such performance is otherwise required under this Agreement.

     28.3  In the event the Landlord or any of its successors or assigns is an
individual, partnership, joint venture, association or a participant in a joint
tenancy or tenancy in common, the Landlord, the partners, venturers, members and
joint owners and any successors and assigns of the Landlord shall not have any
personal liability or obligation under or in connection with this Agreement or
the Tenant's use and occupancy of the Leased Premises; but recourse shall be
limited exclusively to the Landlord's interest and the Landlord's successors and
assigns in the Building, including, but not limited to, rents, insurance
proceeds and condemnation awards received thereby.

     28.4  If, at any time during the Term, the payment or collection of any
Rent otherwise due under this Agreement shall be limited, frozen or otherwise
subjected to a moratorium by applicable law, and such limitation, freeze or
other moratorium shall subsequently be lifted, whether before or after the
termination of the Term, such aggregate amount of Rent as shall not have been
paid or collected during the Term on account of any such limitation, freeze or
other

                                       39


moratorium, shall thereupon be due and payable at once. There shall be added to
the maximum period of any otherwise applicable statute of limitation the entire
period during which any such limitation, freeze or other moratorium shall have
been in effect.

     28.5  If this Agreement is executed by more than one person as Tenant,
their liability under this Agreement and in connection with the use and
occupancy of the Leased Premises shall be joint and several.

     28.6  In the event any rate of interest, or other charge in the nature of
interest, calculated as set forth in this Agreement would lead to the imposition
of a rate of interest in excess of the maximum rate permitted by applicable
usury law, only the maximum rate permitted shall be charged and collected.

     28.7  The rule of construction that any ambiguities that may be contained
in any contract shall be construed against the party drafting the contract shall
be inapplicable in construing this Agreement.

     28.8  Notwithstanding anything to the contrary that may be set forth in
subsection 28.1 of this Agreement, if (a) electricity or, between May 15/th/ and
September 30/th/ of each year during the Term, building standard air
conditioning or, between October 15/th/ and May 14/th/, heat as needed to the
Building or to the Leased Premises or any material portion of either is
interrupted for a period of more than fifteen (15) consecutive days; and (b) if,
and to the extent, the Tenant is prevented by such interruption from using the
Leased Premises or any material portion thereof; and (c) if the cause of such
interruption is located on the Property and distinctly within the control of the
Landlord to cure (as opposed to interruptions caused by a utility or vendor
outage affecting other properties in the area as well as the Property), then
Rent shall abate, to the extent the Tenant is prevented by such interruption
from using the Leased Premises or any material portion thereof, from the day
after the conclusion of such fifteen (15) day period until such interruption is
so cured that the Tenant may again utilize the Leased Premises or the material
portion thereof it was prevented thereby from using as a result of such
interruption.

                                       40


29  Security Deposit.
    ----------------

     29.1  The Tenant shall pay to the Landlord upon execution and delivery of
this Agreement the sum of $80,553.00 as a security deposit to be held by the
Landlord as security for the Tenant's performance of all the Tenant's
obligations under this Agreement. The Landlord may commingle the Security
Deposit with its general funds. Any interest earned on the Security Deposit
shall belong to the Landlord. The Tenant shall not encumber the Security
Deposit. The Landlord, in its sole discretion, may apply the Security Deposit to
cure any Event of Default under this Agreement. If any such application is made,
upon notice by the Landlord to the Tenant, the Tenant shall promptly replace the
amount so applied. If there has been no Event of Default, within 30 days after
termination of the Term the Landlord shall return the entire balance of the
Security Deposit to the Tenant. The Tenant will not look to any foreclosing
mortgagee of the Property, the Building, the Common Facilities or any interest
therein for such return of the balance of the Security Deposit, unless the
mortgagee has expressly assumed the Landlord's obligations under this Agreement
or has actually received the balance of the Security Deposit.

     29.2  As an alternative to the cash Security Deposit contemplated by
subsection 29.1 of this Agreement, the Tenant may, upon execution and delivery
of this Agreement, deliver to the Landlord an irrevocable letter of credit in
the same amount for the benefit of the Landlord, draws upon which are
conditioned only on the Landlord's certification of the occurrence of an Event
of Default that, at the time of the draw, shall not have been cured in full by
the Tenant. The letter of credit shall be issued by a reputable commercial bank
operating in the United States reasonably satisfactory to the Landlord. The
letter of credit shall be held by the Landlord as a Security Deposit for the
Tenant's performance of all the Tenant's obligations under this Agreement. The
Tenant shall not encumber the Security Deposit. The Landlord, in its sole
discretion, may draw upon the Security Deposit to cure any Event of Default
under this Agreement. If any such application is made, upon notice by the
Landlord to the Tenant, the Tenant shall promptly replace the amount so applied,
either in cash or in the form of an additional letter of credit with otherwise
similar terms. The letter of credit shall be for a term equal to the Term or, if
the issuer of the letter of credit regularly and customarily only issues letters
of credit for shorter terms, for the longest of such shorter regular and
customary terms, but in no event for a term shorter than one year. If the letter
of credit is issued for a term shorter than the Term, the Tenant shall obtain
and deliver to the Landlord a renewal letter of credit for a term equal to the
shorter of (i) the balance of the Term or (ii) the longest of the issuer's
regular and customary terms, no later than 30 days prior to expiration of the
term of the then current letter of credit. If the Tenant shall fail to obtain
and deliver to the Landlord on a timely basis any such conforming renewal letter
of credit, the Landlord shall have the right to draw 100% of the then current
letter of credit and hold the proceeds as a cash Security Deposit in accordance
with subsection 29.1 of this Agreement.

of this Agreement; and

           30.2.4  the Landlord has good right and full power to let and lease

31  Reservation in Favor of Tenant.  Neither the Landlord's forwarding a copy of

Landlord prior to execution and delivery of this Agreement by the Landlord shall
give rise to any implication that any prospective tenant has a reservation, an
option to lease or an outstanding offer to lease any premises.

                                       42

    ------------
application of any provision in any instance, shall be conclusively determined
by a court of competent jurisdiction to be illegal, invalid or otherwise
unenforceable, such determination shall not affect the validity or
enforceability of the balance of this Agreement.

35  Notices. All notices contemplated by, permitted or required by this
    -------
Agreement shall be in writing. All notices required by this Agreement shall be
personally delivered or forwarded by certified mail--return receipt requested,

the case of notices to the Landlord after the Commencement Date, "Attention:
Lease Administration") or, in the case of notices to the Tenant during the Term

amended or otherwise modified except by a writing signed by all the parties to
this Agreement.

42  Waiver.  Except as may otherwise be specifically set forth in this
    ------
Agreement, the failure of any party at any time or times to require performance

later time to enforce the same.  No waiver by any party of any condition, or of
the breach of any term, covenant, representation or warranty set forth in this
Agreement, whether by conduct or otherwise, in any one or more instances shall
be deemed to be or construed as a further or continuing waiver of any such
condition or breach, or as a waiver of any other condition or of the breach of
any other term, covenant, representation or warranty set forth in this
Agreement.

The Landlord's acceptance of, or endorsement on, any partial payment of Rent or
any late payment of Rent from the Tenant shall not operate as a waiver of the
Landlord's right to the balance of the Rent due on a timely basis regardless of
any writing to the contrary on, or accompanying, the Tenant's partial payment or
the Landlord's putative acquiescence therein.

43  Course of Performance.  No course of dealing or performance by the parties,
    ---------------------
or any of them, shall be admissible for the purpose of obtaining an
interpretation or construction of this Agreement at variance with the express
language of the Agreement itself.
