                                  ARTICLE FOUR
                          RENT ADJUSTMENTS AND PAYMENTS



4.01 RENT ADJUSTMENTS

Tenant shall pay to Landlord Rent Adjustments during the Term as follows:


                  (i) Commencing on January 1, 1999, the Rent Adjustment Deposit
         representing Tenant's Share of the increase in Operating Expenses and
         Taxes over the Base Year of 1998 attributable to any calendar year (or
         portion thereof) monthly during the Term at the time when the Monthly
         Base Rent is due; and


                  (ii) Any Rent Adjustments due in excess of the Rent Adjustment
         Deposits in accordance with Section 4.02.


4.02 STATEMENT OF LANDLORD

As soon as feasible (but in no event later than 210 days) after the expiration
of each calendar year of this Lease, Landlord will furnish Tenant a statement
("Landlord's Statement") showing the following:


                  (i) Operating Expenses and Taxes for the Adjustment Year and
         the amount of the increase over the Base Year;


                  (ii) The amount of Rent Adjustments due Landlord for the
         Adjustment Year, less credit for Rent Adjustment Deposits paid, if any;
         and


                  (iii) The Rent Adjustment Deposit due monthly in the calendar
         year next following the Adjustment Year including the amount or revised
         amount due for months prior to the rendition of the statement.



Tenant shall pay to Landlord within thirty (30) days after receipt of such
statement any amounts for Rent Adjustments then due in accordance with
Landlord's Statement. Any amounts due

                                       10





from Landlord to Tenant pursuant to this Section shall be credited to the Rent

Adjustment Deposit next coming due, or at Tenant's election (upon written notice
to Landlord) applied to the next payment of rent, or refunded to Tenant if the
Term has already expired provided Tenant is not in default hereunder. No
interest or penalties shall accrue on any amounts which Landlord is obligated to
credit to Tenant by reason of this Section 4.02. Landlord's failure to deliver
Landlord's Statement or in computing the amount of the Rent Adjustments shall
not constitute a waiver by Landlord of its right to deliver such items nor
constitute a release of Tenant's obligations to pay such amounts unless such
failure shall continue for 365 days after the expiration of each applicable
calendar year during the term of this Lease. The Rent Adjustment Deposit shall
be credited against Rent Adjustments due for the applicable Adjustment Year.
During the last complete calendar year or during any partial calendar year in
which the Lease terminates, Landlord may include in the Rent Adjustment Deposit
its reasonable estimate of Rent Adjustments which may not be finally determined
until after the termination of this Lease. Tenants's obligation to pay Rent
Adjustments (and Landlord's obligation to reimburse Tenant for any excess
estimated payments made by Tenant) survives the expiration or termination of the
Lease. Notwithstanding the foregoing, in no event shall the sum of Monthly Base
Rent and the Rent Adjustments be less than the Monthly Base Rent payable.


4.03 BOOKS AND RECORDS

Landlord shall maintain books and records showing Operating Expenses and Taxes
in accordance with sound accounting and management practices, consistently
applied. Upon written notice and request, Landlord shall make such records
available to Tenant in the State of New Jersey for Tenant review as set forth in
the sentence next following. The Tenant or its representative shall have the
right, for a period of one hundred Eighty (180) days following the date upon
which Landlord's Statement is delivered to Tenant, to examine the Landlord's
books and records with respect to the items in the foregoing statement of
Operating Expenses and Taxes during normal business hours, upon written notice,
delivered at least three (3) business days in advance. If Tenant does not object
in writing to Landlord's Statement within one hundred eighty (180) days of
Tenant's receipt thereof, specifying the nature of the item in dispute and the
reasons therefor, then Landlord's Statement shall be considered final and
accepted by Tenant. Any amount due to the Landlord as shown on Landlord's
Statement, whether or not disputed by Tenant as provided herein shall be paid by
Tenant when due as provided above, without prejudice to any such written
exception. Any dispute between Landlord and Tenant as to the matters which are
the subject of this Section 4.03 shall be resolved pursuant to Section 26.18
hereof.


4.04 PARTIAL OCCUPANCY

For purposes of determining Rent Adjustments for any Adjustment Year if the
Building is not fully rented during all or a portion of any year (including the
Base Year), Landlord shall make appropriate adjustments to the Operating
Expenses (that is, that portion thereof that would vary with occupancy levels)
for such Adjustment Year (including the Base Year) employing sound

                                       11






accounting and management principles consistently applied, to determine the
amount of Operating Expenses that would have been paid or incurred by Landlord
had the Building been 95% occupied, and the amount so determined shall be deemed
to have been the amount of Operating Expenses for such Adjustment Year. In the
event that the Real Property is not fully assessed for any year (including the
Base Year), then Taxes shall be adjusted to an amount which would have been
payable in such year (including the Base Year) if the Real Property had been
fully assessed (which estimated adjustment shall be revised, if necessary, to
reflect the actual full assessment and the Landlord and Tenant shall thereafter
reconcile any under or over payment made based on such readjustment). In the
event any other tenant in the Building provides itself with a service which
Landlord would supply under the Lease without an additional or separate charge
to Tenant, then Operating Expenses shall be deemed to include the cost Landlord
would have incurred had Landlord provided such service to such other tenant (but
only to the extent the cost for such service was included in Operating Expenses
for the Base Year.

applied by Landlord to.cure any default of Tenant under this Lease, and upon
notice by Landlord of such application, Tenant shall replenish the Security
Deposit in full by paying to Landlord within ten (10) days of demand the amount
so applied. Landlord shall not pay any interest on the Security Deposit. The
Security Deposit shall not be deemed an advance payment of Rent, nor a measure
of damages for any default by Tenant under this Lease, nor shall it be a bar or
defense of any action which Landlord may at any time commence against Tenant. In
the absence of evidence satisfactory to Landlord of an assignment of the right
to receive the Security Deposit or the remaining balance thereof, Landlord may
return the Security Deposit to the original Tenant, regardless of one or more
assignments of this Lease. Upon the transfer of Landlord's interest under this
Lease (and the written assumption by the transferee of the Landlord's
obligations hereunder with respect to the Security Deposit), Landlord's
obligation to Tenant with respect to the Security Deposit shall terminate upon
assumption of such obligation by the transferee.


If Tenant shall fully and faithfully comply with all the terms, provisions,
covenants, and conditions of this Lease, the Security Deposit, or any balance
thereof, shall be returned to Tenant after the following:




                                       12

without limitation, all Rent Adjustments due pursuant to the Lease as computed
by Landlord.

         Notwithstanding the foregoing, Tenant at Tenant's election, which
election shall be exercised by delivery to Landlord of an additional irrevocable
and unconditional letter of credit in the amount of $122,370.01 at least 90 days
prior to the expiration of the (i) term of this Lease (if No Renewal Option is
exercised) or (ii) any properly exercised Renewal Option, may elect, which
election shall be indicated in writing together with the delivery of the
additional irrevocable letter of credit, as set forth above, to have Landlord
apply the cash portion of the Security Deposit to the base rental payments for
the final three months of the then existing Term of this Lease or the properly
exercised Renewal Option. The additional letter of credit shall constitute a
portion of the Security Deposit and shall be applied or returned to Tenant as
set forth in this Lease. Upon the deposit with Landlord of such additional
letter of credit, the $163,166.68 letter of credit shall be delivered to
Landlord's counsel, to be held in escrow and applied or returned to Tenant
pursuant to the terms of this Lease.

invalidate, any policy of insurance carried on the Building or covering its
operations; (3) is contrary to or prohibited by the terms and conditions of this
Lease or the rules of the Building set forth in Article Eighteen; or (4) would
tend to create or continue a nuisance. Landlord represents that as of the
Commencement Date hereof, the use of the Premises for general office use will
not violate the Zoning Ordinance of Upper Saddle River, New Jersey.

         (b) Tenant and Landlord shall each comply with all Environmental Laws
concerning the proper storage, handling and disposal of any Hazardous Material
with respect to the Property. Tenant shall not generate, store, handle or
dispose of any Hazardous Material in, on, or about the Property without the
prior written consent of Landlord. Nothing herein shall prohibit the Tenant from
using reasonable quantities of properly packaged supplies which may contain
Hazardous Materials but which are customly present in premises devoted to office
use, provided that such use is in compliance with Environmental Laws. In the
event that Tenant is notified of any investigation or violation of any
Environmental Law arising from Tenant's activities at the Premises, Tenant shall

immediately deliver to Landlord a copy of such notice. In such event or in the
event Landlord reasonably believes that a violation of Environmental Law exists,
Landlord may conduct such tests and studies relating to compliance by Tenant
with Environmental Laws or the alleged presence of Hazardous Materials upon the
Premises as Landlord deems desirable, all of which shall be completed at
Tenant's expense. However, if such tests and/or studies were initiated and/or
required only by Landlord then in that event, Tenant shall be required to pay
for the same only if the test and/or studies reveal a situation in violation of
any Environmental Laws to which Tenant is responsible. Landlord's inspection and
testing rights are for Landlord's own protection only, and Landlord has not, and
shall not be deemed to have assumed any responsibility to Tenant or any other
party for compliance with Environmental Laws, as a result of the exercise, or
non-exercise of such rights. Tenant shall indemnify, defend, protect and hold
harmless the Indemnitees from any and all loss, claim, expense, liability and
cost (including attorneys' fees) arising out of or in any way related to the

                                       16





presence of any Hazardous Material introduced to the Premises, except as above
permitted, during the Lease Term by any party other than Landlord. If any
Hazardous Material is released, discharged or disposed of on or about the
Property and such release, discharge or disposal is not caused by Tenant or
other occupants of the Premises, or their employees, agents or contractors, such
release, discharge or disposal shall be deemed casualty damage under Article
Fourteen to the extent that the Premises are affected thereby; in such case,
Landlord and Tenant shall have the obligations and rights respecting such
casualty damage provided under such Article.

         (c) Landlord and Tenant acknowledge that the Americans With
Disabilities Act of 1990 (42 U.S.C S12101 et seq.) and regulations and
guidelines promulgated thereunder, as all of the same may be amended and
supplemented from time to time (collectively referred to herein as the "ADA")
establish requirements for business operations, accessibility and barrier
removal, and that such requirements may or may not apply to the Premises and the
Building depending on, among other things: (1) whether Tenant's business is
deemed a "public accommodation" or "commercial facility", (2) whether such
requirements are "readily achievable", and (3) whether a given alteration
affects a "primary function area" or triggers "path of travel" requirements. The
parties hereby agree that: (a) Landlord shall be responsible for ADA Title III
compliance in the Common Areas, except as provided below, (b) except for initial
Landlord's Work actually performed by Landlord or Landlord's agents, Tenant
shall be responsible for ADA Title III compliance in the Premises, and (c)
Landlord may perform, or require that Tenant perform, and Tenant shall be
responsible for the cost of, ADA Title III "path of travel" requirements
triggered by Tenant Alterations in the Premises. Tenant shall be solely
responsible for requirements under Title I of the ADA relating to Tenant's
employees.


7.02     LANDLORD ACCESS TO PREMISES


         (a) Tenant shall permit Landlord to erect, use and maintain pipes,
ducts, wiring and conduits in and through the Premises, so long as Tenant's use,
layout or design of the Premises is not materially affected or altered. Landlord
or Landlord's agents shall have the right to enter upon the Premises in the
event of an emergency, or to inspect the Premises, to perform janitorial and
other services, to conduct safety and other testing in the Premises and to make
such repairs, alterations, improvements or additions to the Premises or the
Building as Landlord may deem necessary or desirable upon not less than one (1)
business day prior notice to Tenant (unless an emergency exists in which event
no prior notice shall be required). Janitorial and cleaning services shall be
performed after normal business hours. In connection therewith, Landlord shall
be allowed to store on the Premises all necessary supplies and materials unless
the same will materially interfere with Tenant's conduct of business from the
Premises. Any entry or work by Landlord may be during normal business hours upon
one (1) business day prior notice to Tenant (except in the event of an emergency
with respect to which any entry or work may be done at any time) and Landlord
shall use reasonable efforts to see that any entry or work shall not materially
interfere with Tenant's occupancy of the Premises.



                                       17





         (b) If Tenant shall not be personally present to permit an entry into
the Premises when for any reason an entry therein shall be necessary or
permissible, Landlord (or Landlord's agents), after attempting to notify Tenant
(unless Landlord believes an emergency situation exists), may enter the Premises
without rendering Landlord or its agents liable therefor (if during such entry
Landlord or Landlord's agent shall accord reasonable care to Tenant's property),
and without relieving Tenant of any obligations under this Lease.


         (c) Landlord may upon not less than one (1) business day prior notice
to Tenant (unless an emergency exists in which event no prior notice shall be
required) enter the Premises, in the presence of a representative of the Tenant,
for the purpose of conducting such inspections, tests and studies as Landlord
may deem desirable or necessary to confirm Tenant' s compliance with all Laws
and Environmental Laws or for other purposes necessary in Landlord's reasonable
judgment to ensure the sound condition of the Building and the systems serving
the Building. Landlord's rights under this Section 7.02(c) are for Landlord's
own protection only, and Landlord has not, and shall not be deemed to have
assumed any responsibility to Tenant or any other party for compliance with Laws
or Environmental Laws, as a result of the exercise or non-exercise of such
rights.

         (d) Provided that Landlord acts reasonably to complete the work and/or
inspections as above provided then Landlord may do any of the foregoing, or
undertake any of the inspection or work described in the preceding paragraphs
without such action constituting an actual or constructive eviction of Tenant,

in whole or in part, or giving rise to an abatement of Rent by reason of loss or
interruption of business of the Tenant, or otherwise. Landlord shall, in doing
the foregoing, use reasonable efforts to minimize the interference with the
Tenant's conduct of business from the Premises.

7.03 QUIET ENJOYMENT

Landlord covenants that so long as Tenant is in compliance with the covenants
and conditions set forth in this Lease, Tenant shall have the right to quiet
enjoyment of the Premises without hindrance or interference from Landlord or
those claiming through Landlord.




7.04 COMPLIANCE WITH LAWS

Tenant shall comply with and execute at its own expense during and throughout
the term of this Lease, all Laws, ordinary or extraordinary, foreseen or
unforeseen, concerning the Tenant's Premises and the Tenants use and occupancy
thereof. Any law relating to the Building, and having application to the
Building regardless of the use made thereof, shall be the responsibility of the
Landlord and shall be considered an Operating Expense to the extent permitted by
the terms of this Lease, and except that as to the compliance with any
Environmental Law by

                                       18





Landlord as may be required by this Section 7.04 Tenant's payment in connection
with Tenant's Share's on an annual basis throughout the Term of this Lease
applicable to such compliance shall not exceed $15,000.00.



7.05 PERMITS

Except as specifically provided to the contrary in this Lease, Tenant shall be
responsible, at Tenant's expense, for obtaining any and all licenses, permits,
authorizations and approvals which may be required by any Law to be obtained for
the proper and lawful conduct of Tenant's business in the Premises.


                                  ARTICLE EIGHT
                                   MAINTENANCE


8.01 LANDLORD'S MAINTENANCE

Subject to the provisions of Article Fourteen, Landlord shall maintain and make
necessary repairs to the foundations, roofs, exterior walls, common areas,

parking areas, landscaping, and the structural elements of the Building, the
electrical, plumbing, heating, ventilation and air-conditioning systems of the
Building and the public corridors, washrooms and lobby of the Building, except
that: (a) Landlord shall not be responsible for the maintenance or repair of any
floor coverings or wall coverings in the Premises or any of such systems which
are located within the Premises; and (b) the cost of performing any of said
maintenance or repairs whether to the Premises or to the Building caused by the
negligence of Tenant, its employees, agents, servants, licensees, subtenants,
contractors or invitees, shall be paid by Tenant, provided, however, Landlord
agrees to credit Tenant with any insurance proceeds paid to Landlord or which
would have been payable to Landlord had Landlord maintained the insurance
required to be maintained by Landlord under the terms and conditions of this
Lease. Landlord shall not be liable to Tenant for any expense, injury, loss or
damage resulting from work done in or upon, or the use of, any adjacent or
nearby building, land, street, or alley.


8.02 TENANT'S MAINTENANCE

Subject to the provisions of Article Fourteen, Tenant, at its expense, shall
keep and maintain the Premises and all systems and items located therein that
exclusively serve the Premises, and all Tenant Additions in good order,
condition and repair (reasonable wear and tear and damage caused by fire or
other casualty excepted) and in accordance with all Laws and Environmental Laws.
Tenant shall not permit waste and shall promptly and adequately repair all
damages to the Premises and replace or repair all damaged or broken glass in the
interior of the Premises,

                                       19





fixtures or appurtenances unless caused by the negligence of Landlord or its
agents or representatives provided, however, Landlord agrees to credit Tenant
with any insurance proceeds paid to Landlord or which would have been payable to
Landlord had Landlord maintained the insurance required to be maintained by
Landlord under the terms and conditions of this Lease. Any repairs or
maintenance shall be completed with materials of similar quality to the original
materials, all such work to be completed under the supervision of Landlord. Any
such repairs or maintenance shall be performed only by contractors or mechanics
approved by Landlord, which approval shall not be unreasonably withheld,
conditioned or delayed, and whose work will not cause or threaten to cause
disharmony or interference with Landlord or other tenants in the Building and
their respective agents and contractors performing work in or about the
Building. If Tenant fails to perform any of its obligations set forth in this
Section 8.02, Landlord may, in its sole discretion and upon one (1) business day
prior notice to Tenant (except in the case of emergencies), perform the same,
and Tenant shall pay to Landlord any reasonable costs or expenses incurred by
Landlord within 30 days after demand.

                                  ARTICLE NINE
                          ALTERATIONS AND IMPROVEMENTS


9.01 TENANT'S ALTERATIONS

         (a) The following provisions shall apply to the completion of any
Tenant Alterations:


(1)      Tenant shall not, except as provided herein, without the prior written
         consent of Landlord, which consent shall not be unreasonably withheld,
         conditioned or delayed, make or cause to be made any Tenant Alterations
         in or to the Premises or any Building systems serving the Premises.
         Prior to making any Tenant Alterations, Tenant shall give Landlord ten
         (10) days prior written notice (or such earlier notice as would be
         necessary pursuant to applicable Law) to permit Landlord sufficient
         time to post appropriate notices of nonresponsibility. At the time that
         Landlord may respond in the affirmative to any request by Tenant to
         make such Tenant Alterations, Landlord shall advise Tenant whether or
         not Tenant shall be required to remove the Tenant Alterations upon the
         expiration of the Lease Term. Tenant may remove any Tenant's
         Alterations whether or not Landlord requires the same to be removed
         pursuant to the preceding sentence and such removal shall be performed
         in accordance with Article 12 of this Lease. Subject to all other
         requirements of this Article Nine, Tenant may undertake Decoration work
         without Landlord's prior written consent. Tenant shall furnish Landlord
         with the names and addresses of all contractors and subcontractors and
         copies of all contracts. All Tenant Alterations shall be completed at
         such time and in such manner as Landlord may from time to time
         reasonably designate, and only by contractors or mechanics approved by
         Landlord (except no such approval need be obtained with respect to
         Decorations), which approval shall not be unreasonably withheld, and
         whose work will not cause or threaten to cause disharmony or
         interference with Landlord or other tenants in the Building and their
         respective agents and contractors performing work in or about the
         Building. Any

                                       20





         contractor designated by Landlord as set forth above shall charge
         competitive rates for the completion of Tenant's Alterations. Landlord
         may further condition its consent upon Tenant furnishing to Landlord
         and Landlord approving prior to the commencement of any work or
         delivery of materials to the Premises related to the Tenant Alterations
         such of the following as specified by Landlord: architectural plans and
         specifications (if required by the permitting agency), opinions from
         engineers reasonably acceptable to Landlord stating that the Tenant
         Alterations will not unreasonably affect the Building's systems,
         including, without limitation, the mechanical, heating, plumbing,
         security, ventilating, air-conditioning, electrical, and the fire and
         life safety systems in the Building, necessary permits and licenses,
         certificates of insurance. Landlord may, in the exercise of reasonable

         judgment, request that Tenant provide Landlord with appropriate
         evidence of Tenant's ability to complete and pay for the completion of
         the Tenant Alterations such as a performance bond or letter of credit.
         A performance bond shall be required for all Tenant Alterations costing
         in excess of $30,000.00 in any single instance. Upon completion of the
         Tenant Alterations, Tenant shall deliver to Landlord an as-built set of
         plans and specifications for the Tenant Alterations.


(2)      Tenant shall pay the cost of all Tenant Alterations and the cost of
         decorating the Premises and any work to the Building occasioned
         thereby. In connection with completion of any Tenant Alterations,
         Tenant shall pay Landlord a construction fee equal to three (3%)
         percent of the construction cost of such Tenant Alterations and all
         elevator and hoisting charges at Landlord's then standard reasonable
         rate. Upon completion of Tenant Alterations, Tenant shall furnish
         Landlord with contractors' affidavits and full and final waivers of
         lien and receipted bills covering all labor and materials expended and
         used in connection therewith and such other documentation reasonably
         requested by Landlord or Mortgagee.


(3)      Tenant agrees to complete all Tenant Alterations (i) in accordance with
         all Laws, Environmental Laws, all requirements of applicable insurance
         companies and in accordance with Landlord's standard construction rules
         and regulations, and (ii) in a good and workmanlike manner with the use
         of good grades of materials. Tenant shall notify Landlord immediately
         if Tenant receives any notice of violation of any Law in connection
         with completion of any Tenant Alterations and shall immediately take
         such steps as are necessary to remedy such violation. In no event shall
         such supervision or right to supervise by Landlord nor shall any
         approvals given by Landlord under this Lease constitute any warranty by
         Landlord to Tenant of the adequacy of the design, workmanship or
         quality of such work or materials for Tenant's intended use, or of
         compliance with the requirements of Section 9.01(a) (3) (i) and (ii)
         above or impose any liability upon Landlord in connection with the
         performance of such work.



                                       21





         (b) All Tenant Alterations whether installed by Landlord or Tenant,
         shall without compensation or credit to Tenant, become part of the
         Premises and the property of Landlord at the time of their installation
         and shall remain in the Premises, unless pursuant to Article Twelve,
         Tenant removes them or is required to remove them at Landlord's
         request. Tenant shall not be required to remove the Landlord's Work
         installed as of the Commencement Date of this Lease.



9.02 LIENS

Tenant shall not permit any lien or claim for lien of any mechanic, laborer or
supplier or any other lien to be filed against the Building, the Land, the
Premises, or any part thereof arising out of work performed, or alleged to have
been performed by, or at the direction of, or on behalf of Tenant. If any such
lien or claim for lien is filed, Tenant shall within thirty (30) days (or ten
(10) days, if necessary, to avoid interference in Landlord's consummating a
transaction involving the Building) of receiving notice of such lien or claim
(a) have such lien or claim for lien released of record or (b) deliver to
Landlord a bond in form, content, amount, and issued by surety, reasonably
satisfactory to Landlord, indemnifying, protecting, defending and holding
harmless the Indemnitees against all costs and liabilities resulting from such
lien or claim for lien and the foreclosure or attempted foreclosure thereof. If
Tenant fails to take any of the above actions, Landlord, without investigating
the validity of such lien or claim for lien, may pay or discharge the same and
Tenant shall, as payment of additional Rent hereunder, reimburse Landlord upon
demand for the reasonable amount so paid by Landlord, including Landlord's
reasonable expenses and reasonable attorneys' fees.



                                   ARTICLE TEN
                            ASSIGNMENT AND SUBLETTING


10.01    ASSIGNMENT AND SUBLETTING

         (a) Without the prior written consent of Landlord, Tenant may not
sublease, assign, mortgage, pledge, hypothecate or otherwise transfer or permit
the transfer of this Lease or the encumbering of Tenant's interest therein in
whole or in part, by operation of law or otherwise or permit the use or
occupancy of the Premises, or any part thereof, by anyone other than Tenant. If
Tenant desires to enter into any sublease of the Premises or assignment of this
Lease, Tenant shall deliver written notice thereof to Landlord ("Tenant's
Notice"), together with the identity of the proposed subtenant or assignee and
the proposed principal terms thereof and financial and other information
sufficient for Landlord to make an informed judgment with respect to such
proposed subtenant or assignee at least thirty (30) days prior to the
commencement dated of the term of the proposed sublease or assignment. If Tenant
proposes to sublease less than all of the Rentable Area of the Premises, the
space proposed to be sublet and the space retained by Tenant must each be a
marketable unit as reasonably determined by Landlord and otherwise in compliance
with all Laws. Landlord shall notify Tenant in writing 

                                      22




of its approval or disapproval of the proposed sublease or assignment or its
decision to exercise its rights under Section 10.02 within twenty (20) days
after receipt of Tenant's Notice (and all required information). In no event may

Tenant sublease any portion of the Premises or assign the Lease to any other
tenant of the Building. Tenant shall submit for Landlord's approval (which
approval shall not be unreasonably withheld) any advertising which Tenant or its
agents intend to use with respect to the space proposed to be sublet or
assigned.


         (b) In making its determination of whether to consent to any proposed
sublease or assignment (which consent, subject to the provisions of this
subsection (b) shall not be unreasonably withheld or conditioned), Landlord may
take into consideration the business reputation and credit-worthiness of the
proposed subtenant or assignee; the nature of the business conducted by such
subtenant or assignee and whether such business would be deleterious to the
reputation of the Building or Landlord or would violate the provisions of any
other leases of tenants of the Building; the estimated pedestrian and vehicular
traffic in the Premises and to the Building which would be generated by the
proposed subtenant or assignee; whether the proposed assignee or subtenant is a
department, representative or agency of any governmental body, foreign or
domestic; and any other factors which Landlord shall deem relevant. In no event
shall Landlord be obligated to consider a consent to any proposed (i) sublease
of the Premises or assignment of the Lease if a Default then exists under the
Lease, or (ii) assignment of the Lease which would assign less than the entire
Premises.


         (c) If Landlord chooses not to recapture the space proposed to be
subleased or assigned as provided in Section 10.02, Landlord shall not
unreasonably withhold, delay or condition its consent to a subletting or
assignment under this Section 10. 01. Any approved sublease or assignment shall
be expressly subject to the terms and conditions of this Lease. Any such
subtenant or assignee shall execute such documents as Landlord may reasonably
require to evidence such subtenant's agreement to or assignee's assumption of
such obligations and liabilities. Tenant shall deliver to Landlord a copy of all
agreements executed by Tenant and the proposed subtenant and assignee with
respect to the Premises. Landlord's approval of a sublease or assignment shall
not constitute a waiver of Landlord's right to consent to further assignments or
subleases.


         (d) For purposes of this Article Ten, an assignment shall be deemed to
include a change in the majority control of Tenant, resulting from any transfer,
sale or assignment of shares of stock of Tenant occurring by operation of law or
otherwise if Tenant is a corporation whose shares of stock are not traded
publicly. If Tenant is a partnership, any change in the partners of Tenant shall
be deemed to be an assignment. The provisions of this subsection (d) shall not
be applicable to Tenant if it is a corporation whose stock is publicly traded.

                                       23




         (e) Landlord shall have no right to withhold consent to any assignment
of this Lease or to any subletting to a majority owned subsidiary of Tenant, its

parent or such other corporation which has more than fifty (50%) percent of
common legal and beneficial ownership, provided such does not result in a change
in the use of the Premises and provided further that such assignee continues to
be after such assignment a majority-owned subsidiary of Tenant, Tenant's parent
or other corporation which has more than fifty (50%) percent of common legal and
beneficial ownership of Tenant. In such case, Tenant shall remain directly and
primarily liable for the performance of the terms and conditions of this Lease.
Landlord shall have no right to withhold consent to any assignment of this Lease
or to any subletting in connection with a sale of Tenant's business, inclusive
of the Demised Premises, provided that the purchaser has a tangible net worth at
the time of such transaction equal to or greater than the greater of: (i)
Tenant's tangible net worth on the date of this Lease, or (ii) Tenant's tangible
net worth on the date of such transaction.

10.02     RECAPTURE

Except as provided in Section 10.01(e) Landlord shall have the option to exclude
from the Premises covered by this Lease ("recapture"), the entire space proposed
to be sublet or subject to the assignment, effective as of the proposed
commencement date of such sublease or assignment in any case where the Tenant
proposes to sublet or assign 6,600 square feet or more of the Premises. If
Landlord elects to recapture, Tenant shall surrender possession of the space
proposed to be subleased or subject to the assignment to Landlord on the
effective date of recapture of such space from the Premises such date being the
Termination Date for such space. Effective as of the date of recapture of any
portion of the Premises pursuant to this section, the Monthly Base Rent,
Rentable Area of the Premises and Tenant's Share shall be adjusted accordingly.



10.03    EXCESS RENT

(a) Tenant shall pay Landlord on the first day of each month during the term of
the sublease, fifty percent (50%) of the amount by which the sum of all rent and
other consideration (direct or indirect) but exclusive of any amount received
for the sale of all furniture, fixtures and equipment that does not exceed the
unamortized value thereof received from the subtenant for such month exceeds:
that portion of the Monthly Base Rent and Rent Adjustments due under this Lease
for said month which is allocable to the space sublet, less all reasonable costs
and expenses for the subletting of such space including but not limited to: (1)
brokerage commissions and attorneys' fees and expenses, (2) advertising for
subtenants; (3) the actual costs paid in making any improvements or
substitutions in the Premises required by any sublease; and (4) "free rent"
periods, costs of any inducements or concessions given to subtenant, moving
costs, and other amounts in respect of such subtenant's other leases or
occupancy arrangements.


                                       24






(b) Except as set forth in (a) above, Tenant shall pay Landlord on the effective
date of the assignment fifty (50%) percent of the amount of all consideration
(direct or indirect) received from the assignee, less reasonable costs and
expenses for the assignment of such space, including but not limited to: (1)
brokerage commissions and attorney's fees and expenses; (2) advertising for
assignees; (3) the actual costs paid in making any improvements or substitutions
in the Premises required by any assignment; and (4) "free rent" periods, costs
of any inducements or concessions given to assignee, moving costs, and other
amounts in respect of such assignee's other leases or occupancy arrangements.



10.04     TENANT LIABILITY

In the event of any sublease or assignment, Tenant shall not be released or
discharged from and shall remain jointly and severally primarily liable for any
liability, whether past, present or future, under this Lease, including any
liability arising from the exercise of any renewal or expansion option.



10.05     ASSUMPTION AND ATTORNMENT

If Tenant shall assign this Lease as permitted herein, the assignee shall
expressly assume all of the obligations of Tenant hereunder from and after the
date of the Assignment in a written instrument reasonably satisfactory to
Landlord and furnished to Landlord upon execution thereof. If Tenant shall
sublease the Premises as permitted herein, Tenant shall, at Landlord's option,
within fifteen (15) days following any request by Landlord, obtain and furnish
to Landlord the written agreement of such subtenant to the effect that the
subtenant will attorn to Landlord and will pay all subrent directly to Landlord.


                                 ARTICLE ELEVEN
                              DEFAULT AND REMEDIES


11.01     EVENTS OF DEFAULT

The occurrence or existence of any one or more of the following shall constitute
a "Default" by Tenant under this Lease:


               (i) Tenant fails to pay any installment or-other payment of Rent
         including without limitation Rent Adjustment Deposits or Rent
         Adjustments within five (5) days after notice that the same was not
         paid when due;

                                       25







            (ii) Tenant fails to observe or perform any of the other covenants,
         conditions or provisions of this Lease or Exhibits "B" and/or Exhibit
         "D" and fails to cure such default within thirty (30) days after
         written notice thereof to Tenant (unless the default involves a
         hazardous condition, which shall be cured forthwith), provided that if
         such failure to observe or perform cannot, with the exercise of
         reasonable effort be cured within such thirty (30) day period, the same
         shall not constitute a default if Tenant commences to cure during such
         30 day period and thereafter diligently prosecutes such cure to
         completion;


            (iii) the interest of Tenant in this Lease is levied upon under

11.02     LANDLORD'S REMEDIES

         (a) If a Default occurs, Landlord shall have the rights and remedies
hereinafter set forth, which shall be distinct and cumulative: (i) Landlord may
terminate this Lease by giving Tenant ten (10) days notice of Landlord's
election to do so, in which event, the term of this Lease shall end and all of
Tenant's rights and interests shall expire on the date stated in such notice,
but Tenant shall nevertheless remain liable for the payment of Rent and all
other sums due, payable and/or owing by it hereunder, which obligations shall
expressly survive the termination of this Lease; (ii) Landlord may terminate
Tenant's right of possession of the Premises without terminating this Lease by
giving ten (10) days notice to Tenant that Tenant's right of possession shall
end on the date specified in such notice but Tenant shall nevertheless remain
liable for the payment of Rent and all other sums due, payable and/or owing by
it hereunder; or (iii) Landlord may enforce the provisions of this Lease and may
enforce and protect the rights of the Landlord hereunder by a suit or suits in
equity or at law for the specific performance of any covenant or agreement
contained herein, or for the enforcement of any other appropriate legal or
equitable remedy, including recovery of all monies due or to become due for the
balance of the Term from Tenant under any of the provisions of this Lease.



                                       26




            (b) (1) In the event that Landlord terminates the Lease or Tenant's
right to possession, Landlord shall be entitled to recover as damages for loss
of the bargain and not as a penalty, Rent for the balance of the Term as and
when due, plus all Landlord's expenses of reletting, including without
limitation, repairs, alterations, improvements, additions, decorations, legal
fees and brokerage commissions (collectively, the "Reletting Expenses"), less
any rent received by Landlord for the Premises during such period.

                (2) No termination of this Lease by Landlord as provided herein
shall relieve Tenant of its liability and obligations under this Lease, and such
liability and obligations shall survive any such termination. In the event of
any such termination, whether or not the Premises shall have been relet, Tenant
shall pay to Landlord each month the base rent and additional rent and other
payments required to be paid by Tenant up to the time of such termination, and
thereafter Tenant, until the end of what would have been the term of this Lease
in the absence of such termination, shall be liable to Landlord for, and shall
pay to Landlord each month:

                  (i) The amount of the base rent, additional rent and other
payments which would be payable under this Lease by Tenant if this Lease were
still in effect together with any and all reasonable costs of any kind or nature
whatsoever, paid or incurred by Landlord as a result of such termination, which
costs shall be payable by Tenant forthwith, less

                  (ii) The net proceeds, if any, of any reletting, after
deducting all of Landlord's expenses in connection with such reletting,
including all repossession costs, brokerage commissions, legal expenses,
reasonable attorneys' fees, alteration costs, repairs and other reasonable
expenses of preparation for such reletting.

Tenant shall pay such current damages (herein called "deficiency") to Landlord
monthly on the days on which the base rent would have been payable under this
Lease if this Lease were still in effect, and Landlord shall be entitled to
recover from Tenant each monthly deficiency as the same shall arise. However, if
Landlord in its sole discretion so elects, at any time after any such
termination, Tenant shall pay to Landlord, within thirty (30) days of Landlord's
demand thereof, as and for liquidated and agreed final damages for Tenant's
default, an amount equal to the difference between the base rent, additional
rent and other payments hereunder for the unexpired portion of the term of this
Lease and the then fair and reasonable rental value of the Premises for the same
period discounted to present value based on the then current discount rate. If
the whole or any part of the Premises be relet by Landlord for the unexpired
term of this Lease or any portion thereof in an arms length transaction, before
presentation of proof of such liquidated damages to any court, commission or
tribunal, the amount of rent reserved upon such reletting shall be deemed the
fair and reasonable rental value for the whole or part of the Premises so relet
during the term of the reletting. Nothing herein contained shall limit or

prejudice the right of Landlord to prove for and obtain as liquidated damages by
reason of such termination, an amount equal to the maximum allowed by any
statute or rule of law in effect at the time, whether or not such amount be
greater, equal to, or less than the amount of the differences referred to above.

                                       27




         (c) In the event Landlord proceeds pursuant to subparagraph (a)(i) or
(ii) above, Landlord may, but shall not be obligated to relet the Premises, or
any part thereof for the account of Tenant, for such rent and term and upon such
terms and conditions as are reasonably acceptable to Landlord. For purposes of
such reletting, Landlord is authorized to decorate, repair, alter and improve
the Premises to the extent reasonably necessary or desirable. If the Premises
are relet and the consideration realized therefrom after payment of all
Landlord's Reletting Expenses, is insufficient to satisfy the payment when due
of Rent reserved under this Lease for any monthly period, then Tenant shall pay
Landlord upon demand any such deficiency monthly. If such consideration is
greater than the amount necessary to pay the full amount of the Rent, the full
amount of such excess shall be retained by Landlord (and shall in no event be
payable to Tenant) and applied against any deficiency of Tenant hereunder.
Tenant agrees that Landlord may file suit to recover any sums due to Landlord
hereunder from time to time and that such suit or recovery of any amount due
Landlord hereunder shall not be any defense to any subsequent action brought for
any amount not theretofore reduced to judgment in favor of Landlord.

         (d) In the event a Default occurs, Landlord may, at Landlord's option,
and pursuant to and with process of law, enter into the Premises, remove
Tenant's property, fixtures, furnishings, signs and other evidences of tenancy,
and take and hold such property; provided, however, that such entry and
possession shall not terminate this Lease or release Tenant, in whole or in
part, from Tenant's obligation to pay the Rent reserved hereunder for the full
Term or from any other obligation of Tenant under this Lease. Any and all
property which may be removed from the Premises by Landlord pursuant to the
authority of law, to which Tenant is or may be entitled, may be handled, removed
or stored by Landlord at the risk, cost and expense of Tenant, and Landlord
shall in no event, absent Landlord's gross negligence, be responsible for the
value, preservation or safekeeping thereof. Tenant shall pay Landlord, upon
demand, any and all reasonable expenses incurred in such removal and all storage
charges against such property so long as the same shall be in the Landlord's
possession or under the Landlord's control. Any such property of Tenant not
retaken from storage by Tenant after thirty (30) days notice given to Tenant
after the Termination Date by appropriate legal means shall be conclusively
presumed to have been conveyed by Tenant to Landlord under this Lease as a bill
of sale without further payment or credit by Landlord to Tenant.

         (e) Notwithstanding anything contained herein to the contrary Landlord
waives any common law or statutory right of distraint.


11.03     ATTORNEY'S FEES




                                       28






Tenant or Landlord shall pay upon demand, all reasonable costs and expenses,
including reasonable attorneys' fees, incurred by the other party in enforcing
the performance by Landlord and/or Tenant of any obligations under this Lease,
or resulting from a Default, or incurred by the non-defaulting party in any
litigation, negotiation or transaction in which such non-defaulting party to
become involved or concerned.


11.04     BANKRUPTCY

The following provisions shall apply in the event of the bankruptcy or
insolvency of Tenant:


         (a) In connection with any proceeding under Chapter 7 of the Bankruptcy
Code where the trustee of Tenant elects to assume this Lease for the purposes of
assigning it, such election or assignment, may only be made upon compliance with
the provisions of (b) and (c) below, which conditions Landlord and Tenant
acknowledge to be commercially reasonable. In the event the trustee elects to
reject this Lease then Landlord shall immediately be entitled to possession of
the Premises without further obligation to Tenant or the trustee.


         (b) Any election to assume this Lease under Chapter 11 or 13 of the
Bankruptcy Code by Tenant as debtor-in-possession or by Tenant's trustee (the
"Electing Party") must provide for:

         The Electing Party to cure or provide to Landlord adequate assurance
         that it will cure all monetary defaults under this Lease within thirty
         (30) days from the date of assumption and it will cure all nonmonetary
         defaults (or diligently proceed to cure all nonmonetary default) under
         this Lease within thirty (30) days from the date of assumption.
         Landlord and Tenant acknowledge such condition to be commercially
         reasonable.


         (c) If the Electing Party has assumed this Lease or elects to assign
Tenant's interest under this Lease to any other person, such interest may be
assigned only if the intended assignee has provided adequate assurance of future
performance (as herein defined), of all of the obligations imposed on Tenant
under this Lease.


         For the purposes hereof, "adequate assurance of future performance"
         means that Landlord has ascertained that each of the following

         conditions has been satisfied:


         (i) The assignee has submitted a current financial statement, certified
         by its chief financial officer, which shows a net worth and working
         capital in amounts sufficient to 



                                       29




         assure the future performance by the assignee of Tenant's obligations 
         under this Lease; and



         (ii) Landlord has obtained consents or waivers from any third parties
         which may be required under a lease, mortgage, financing arrangement,
         or other agreement by which Landlord is bound, to enable Landlord to
         permit such assignment.



         (d) Landlord's acceptance of rent or any other payment from any
trustee, receiver, assignee, person, or other entity will not be deemed to have
waived, or waive, the requirement of Landlord's consent, Landlord's right to
terminate this Lease for any transfer of Tenant's interest under this Lease
without such consent, or Landlord's claim for any amount of Rent due from
Tenant.

                                 ARTICLE TWELVE
                              SURRENDER OF PREMISES


12.01     IN GENERAL

Tenant shall not be required to remove the installation which constituted the
Landlord's Work at the commencement of the term hereof. Upon the Termination
Date, Tenant shall surrender and vacate the Premises immediately and deliver
possession thereof to Landlord in a clean, and good condition, ordinary wear and
tear, and damage caused by casualty and Landlord and/or its agents, employees
and servants excepted. Tenant shall deliver to Landlord all keys to the
Premises. Tenant shall be entitled to remove from the Premises all movable
personal property of Tenant, Tenant's trade fixtures and Tenant Alterations.
Tenant shall remove all Tenant Alterations which at the time of their
installation Landlord by notice to Tenant required Tenant to remove. Tenant
shall immediately repair all damage resulting from removal of any of Tenant's
property, furnishings or Tenant Additions, shall close all floor, ceiling and
roof openings and shall restore the Premises to a good condition as reasonably
determined by Landlord. If any of the Tenant Additions which were installed by
Tenant involved the lowering of ceilings, raising of floors or the installation

of specialized wall or floor coverings or lights, then Tenant shall also be
obligated to return such surfaces to their condition prior to the commencement
of this Lease. In the event possession of the Premises is not delivered to
Landlord as required hereunder, or if Tenant shall fail to remove those items
described above, Landlord may, at Tenant's reasonable expense, remove any of
such property therefrom without any liability to Landlord and undertake, at
Tenant's reasonable expense such restoration work as Landlord deems necessary or
advisable.

                                       30




12.02     LANDLORD'S RIGHTS

All property which may be removed from the Premises by Landlord shall be
conclusively presumed to have been abandoned by Tenant and Landlord may deal
with such property as provided in Section 11.02(d). Tenant shall also reimburse
Landlord for all reasonable costs and expenses incurred by Landlord in removing
any of Tenant Alterations and in restoring the Premises to the condition
required by this Lease at the Termination Date.


                                ARTICLE THIRTEEN
                                  HOLDING OVER


Tenant shall pay Landlord the greater of (i) double the monthly Rent (except
that for the first 60 days of the holdover Tenant shall pay 150% rather than
double) payable for the month immediately preceding the holding over (including
increases (but not double) for Rent Adjustments which Landlord may reasonably
estimate) or, (ii) double (except that for the first 60 days of the holdover
Tenant shall pay 150% rather than double) the fair market rental value of the
Premises as reasonably determined by Landlord, for each month or portion thereof
that Tenant retains possession of the Premises, or any portion thereof, after
the Termination Date (without reduction for any partial month that Tenant
retains possession). The provisions of this Article shall not constitute a
waiver by Landlord of any re-entry rights of Landlord and Tenant's continued
occupancy of the Premises shall be as a tenancy in sufferance.



                                ARTICLE FOURTEEN
                        DAMAGE BY FIRE OR OTHER CASUALTY



14.01  SUBSTANTIAL UNTENANTABILITY

         (a) If any fire or other casualty (whether insured or uninsured)
renders all or a substantial portion of the Premises or the Building
untenantable, Landlord shall, with reasonable promptness after the occurrence of
such damage, estimate the length of time that will be required to Substantially

Complete the repair and restoration and shall by notice advise Tenant of such
estimate ("Landlord's Notice"). If Landlord estimates that the amount of time
required to Substantially Complete such repair and restoration will exceed one
hundred eighty (180) days from the date such damage occurred, then Landlord, or
Tenant (but with respect to Tenant only if all or a substantial portion of the
Premises is rendered untenantable and the time period in excess of one hundred
eighty (180) days relates to the repair of the Premises), shall have the right
to terminate this Lease as of the date of such damage upon giving written notice
to the other at any time within twenty (20) days after delivery of Landlord's
Notice, provided that if Landlord so chooses, Landlord's Notice may also
constitute such notice of termination.


                                       31



(b) Unless this Lease is terminated as provided in the preceding subparagraph,
Landlord shall proceed with reasonable promptness, to repair and restore the
Premises to its condition as existed prior to such casualty, subject to
reasonable delays for insurance adjustments and Force Majeure delays, and also
subject to zoning laws and building codes then in effect. Notwithstanding
anything contained herein to the contrary, unless Landlord restores the Premises
to its condition as existed prior to such casualty within three hundred
sixty-five (365) days from the date of the casualty, (inclusive of Force
Majeure) Tenant may cancel this Lease on written notice to Landlord given within
10 days of the expiration of the 365 day period. If such notice to cancel is not
given within the above 10 day period then in that event Tenant shall have no
further right to cancel this Lease.



         (c) Tenant acknowledges that Landlord shall be entitled to the full
proceeds of any insurance coverage, whether carried by Landlord or Tenant, for
damages to the Premises, except for those proceeds of Tenant's insurance of its
own personal property and equipment which would be removable by Tenant at the
Termination Date. All such insurance proceeds shall be payable to Landlord
whether or not the Premises are to be repaired and restored.



         (d) Notwithstanding anything to the contrary herein set forth: (i)
Landlord shall have no duty pursuant to this Section to repair or restore any
portion of any Tenant Additions, or to expend for any repair or restoration of
the Premises or Building amounts in excess of insurance proceeds paid to
Landlord and available for repair or restoration of the Premises or Building
amounts in excess of insurance proceeds paid to Landlord and available for
repair or restoration; and (ii) Tenant shall not have the right to terminate
this Lease pursuant to this Section if any damage or destruction was caused by
the act or neglect of Tenant, its agent or employees.


         (e) Any repair or restoration of the Premises performed by Tenant shall
be in accordance with the provisions of Article Nine hereof.




14.02     INSUBSTANTIAL UNTENANTABILITY

If the Premises or the Building is damaged by a casualty but neither is rendered
substantially untenantable, then Landlord shall proceed to repair and restore
the Building or the Premises other than Tenant Alterations with reasonable
promptness, and unless Landlord completes such repair and restoration on or
before one hundred eighty (180) days following the date of the casualty
(inclusive of Force Majeure) and insurance adjustment, Tenant may cancel this
Lease 


                                       32




on written notice to Landlord given within 10 days of the expiration of the 180
day period. If such notice to cancel is not given within the above 10 day period
then in that event Tenant shall have no further right to cancel this Lease. In
the event of any damage to the Premises which occurs during the last six (6)
months of the Term, either Tenant or Landlord shall have the right to terminate
this Lease as of the date of such casualty by giving written notice thereof to
the other within twenty (20) days after the date of such casualty.



14.03      RENT ABATEMENT

Except for the wilful act of Tenant or its agents, employees, contractors or
invitees, if all or any part of the Premises are rendered untenantable by fire
or other casualty and this Lease is not terminated, Monthly Base Rent and Rent
Adjustments shall abate for that part of the Premises which is untenantable for
the purposes herein permitted on a per diem basis from the date of the casualty
until Landlord has Substantially Completed the repair and restoration work in
the Premises which it is required to perform, provided, that as a result of such
casualty, Tenant does not occupy the portion of the Premises which is
untenantable during such period.

In the event the whole or any substantial part of the Building, the Premises the
ingress or egress to and from public roads, or so much of the parking areas as
to reduce the parking available to a level below that which is required by law,
is taken or condemned by any competent authority for any public use or purpose
(including a deed given in lieu of condemnation), this Lease shall terminate as
of the date title vests in such authority, and Monthly Base Rent and Rent

Adjustments shall be apportioned as of the Termination Date. Notwithstanding
anything to the contrary herein set forth, in the event the taking is temporary
(for less than the remaining term of the Lease) , Landlord may elect either (i)
to terminate this Lease or (ii) permit Tenant to receive the entire award in
which case Tenant shall continue to pay Rent and this Lease shall not terminate.



15.02     TAKING OF PART


In the event a part of the Building or the Premises is taken or condemned by any
competent authority (or a deed is delivered in lieu of condemnation) and this
Lease is not terminated, the Lease shall be amended to reduce, or increase, as
the case may be, the Monthly Base Rent and Tenant's Proportionate Share to
reflect the Rentable Area of the Premises or Building, as the 


                                       33



case  may be, remaining after any such taking or condemnation. Landlord, upon
receipt and to the extent of the award in condemnation (or proceeds of sale)
shall make necessary repairs and restorations to the Premises (exclusive of
Tenant Alterations) and to the Building to the extent necessary to constitute
the portion of the Building not so taken or condemned as a complete
architectural and economically efficient unit. Notwithstanding the foregoing, if
as a result of any taking, or a governmental order that the grade of any street
or alley adjacent to the Building is to be changed and such taking or change of
grade makes it necessary or desirable to substantially remodel or restore the
Building or prevents the economical operation of the Building, Landlord shall
have the right to terminate this Lease upon ninety (90) days prior written
notice to Tenant.


15.03               COMPENSATION

Landlord shall be entitled to receive the entire award (or sale proceeds) from
any such taking, condemnation or sale without any payment to Tenant, and Tenant
hereby assigns to Landlord Tenant's interest, if any, in such award; provided,
however, Tenant shall have the right separately to pursue against the condemning
authority a separate award in respect of the loss, if any, to Tenant for Tenants
furniture, fixtures, equipments and moving expenses paid for by Tenant without
any credit or allowance from Landlord so long as there is no diminution of
Landlord's award as a result.

                                       35




16.04           WAIVER OF SUBROGATION

         (a) Landlord agrees that, if obtainable it will include in its "All
Risks" policies appropriate clauses pursuant to which the insurance companies
(i) waive all right of subrogation against Tenant with respect to losses payable
under such policies and/or (ii) agree that such policies shall not be
invalidated should the insured waive in writing prior to a loss any or all right
of recovery against any party for losses covered by such policies.



         (b) Tenant agrees to include, if obtainable in its "All Risks"
insurance policy or policies on its furniture, furnishings, fixtures and other
property removable by Tenant under the provisions of its lease of space in the
Building appropriate clauses pursuant to which the insurance company or
companies (i) waive the right of subrogation against Landlord and/or any tenant
of space in the Building who waives against Tenant with respect to losses
payable under such policy or policies and/or (ii) agree that such policy or

shall be named as an additional insured in accordance with the foregoing,
Landlord agrees to endorse promptly to the order of Tenant, without recourse,
any check, draft, or order for the payment of money representing the proceeds of
any such policy or representing any other payment growing out of or connected
with said policies, and Landlord does hereby irrevocably waive any and all
rights in and to such proceeds and payments.



         (c) Provided that Landlord's right of full recovery under its policy or
policies aforesaid is not adversely affected or prejudiced thereby, Landlord
hereby waives any and all right of recovery which it might otherwise have
against Tenant, its servants, agents and employees, for loss or damage occurring
to the Building and the fixtures, appurtenances and equipment therein, to the
extent the same is covered by Landlord's insurance, or would have been covered
by Landlord's insurance had Landlord maintained the insurance required to be
maintained by Tenant under the terms and conditions of this Lease,
notwithstanding that such loss or damage may result from the negligence or fault
of Tenant, its servants, agents or employees. Provided that Tenant's right of
full recovery under its aforesaid policy or policies is not adversely affected
or prejudiced thereby, Tenant hereby waives any and all right of recovery which
it might otherwise have against Landlord, its servants, and employees and
against every other tenant in the Building who shall have executed a similar
waiver as set forth in this Section 16.04 (c) for loss or damage to Tenant's
furniture, furnishings, fixtures and other property removable by Tenant under
the provisions hereof to the extent that same is covered by

invalidate the policy as to the other additional insured.

all claims against Indemnitees for, damage to person or property sustained by
the Tenant or any occupant of the Building or Premises resulting directly or
indirectly from any existing or future condition, defect, matter or thing in and
about the Property or the Premises or any part of either or any equipment or
appurtenance therein, or resulting from any accident in or about the Property,
or resulting directly or indirectly from any act or neglect of any tenant or
occupant of the Building or of any other persons, including Landlord's agents
and servants. Tenant hereby waives any consequential damages, compensation or
claims for inconvenience or loss of business, rents, or profits as a result of
such injury or damage regardless of whether caused by Landlord's willful,
negligent or wrongful acts. If any such damage, whether to the Premises or to
any part of the Property or any part thereof, or whether to Landlord or to other
tenants in the Building, results from any act or neglect of Tenant, its
employees, servants, agents, contractors, invitees and 


                                       37





customers, Tenant shall be liable therefor and Landlord may, at Landlord's
option, repair such damage and Tenant shall, upon demand by Landlord, as payment
of additional Rent hereunder, reimburse Landlord within ten (10) days of demand
for the total cost of such repairs, in excess of amounts, if any, paid to
Landlord under insurance covering such damages, or would have been paid to
Landlord had Landlord maintained the insurance required to be maintained by
Landlord under the terms and conditions of this Lease. Tenant shall not be
liable for any damage caused by its acts or neglect if Landlord has recovered
the full amount of the damage from proceeds of insurance policies required to be
maintained under the terms and condition of this Lease.

of Tenant's agents, servants, and/or employees in connection with Tenant's
occupancy of the Premises, from the undertaking of any Tenant Alterations or
repairs to the Premises, from the conduct of Tenant's business on the Premises,
or from any breach or default on the part of Tenant in the performance of any
covenant or agreement on the part of Tenant to be performed pursuant to the
terms of this Lease, or from any willful or negligent act of Tenant, its agents,
contractors, servants, employees, customers or invitees, in or immediately about
the Premises, but only to the extent of Landlord's liability, if any, in excess
of amounts, if any, paid to Landlord under insurance covering such claims or
liabilities. Tenant shall not be responsible for the negligent acts of the
Landlord or Landlord's agents, servants and/or employees. In case of any action
or proceeding brought against the Indemnitees by reason of any such claim, upon
notice from Landlord, Tenant covenants to defend such action or proceeding by
counsel reasonably satisfactory to Landlord, it being understood that counsel
retained by the applicable insurance company shall be deemed satisfactory.

                              MORTGAGEE PROTECTION



23.01     SUBORDINATION AND ATTORNMENT

This Lease is and shall be expressly subject and subordinate at all times to (i)
any ground or underlying lease of the Real Property, now or hereafter existing,
and all amendments, renewals and modifications to any such lease, and (ii) the
lien of any first mortgage or trust deed now or hereafter encumbering fee title
to the Real Property and/or the leasehold estate under any such lease, unless
such ground lease or ground lessor, or mortgage or Mortgagee, expressly provides
or elects that the Lease shall be superior to such lease or mortgage. If any
such mortgage or trust deed is foreclosed, or if any such lease is terminated,
upon request of the Mortgagee or ground lessor, as the case may be, Tenant will
attorn to the purchaser at the foreclosure sale or to the ground lessor under
such lease, as the case may be, provided, however, that such purchaser or ground
lessor shall not be (i) bound by any payment of Rent for more than one month in
advance except for (x) payments in the nature of security for the performance by
Tenant of its obligations under this Lease; and (y) free rent periods as set
forth in Section 1.01(8) of this Lease; (ii) subject to any offset, defense or
damages arising out of a default of any obligations of any preceding Landlord
except to the extent the same continues after Mortgagee has taken possession of
the Premises; (iii) bound by any amendment or modification of this Lease made
without the written consent of the Mortgagee or ground lessor; or (iv) liable
for any security deposits not actually received in cash by such purchaser or
ground lessor. This subordination shall be self-operative and no further
certificate or instrument  of subordination need be required by any such
Mortgagee or ground lessor. In confirmation of such subordination, however,
Tenant shall execute promptly any reasonable certificate or instrument 


                                       41



that Landlord, Mortgagee or ground lessor may request. Upon request by such
successor in interest, Tenant shall execute and deliver reasonable instruments
confirming the attornment provided for herein. Landlord shall use its best
efforts to secure a non-disturbance agreement for the benefit of Tenant from any
future mortgage lien holder on the Building, however failure to secure the
non-disturbance agreement shall not be a default under this Lease.


23.02    MORTGAGEE PROTECTION


Tenant agrees to give any Mortgagee or ground lessor, by registered or certified
mail, a copy of any notice of default served upon the Landlord by Tenant,
provided that prior to such notice Tenant has received notice (by way of service

on Tenant of a copy of an assignment of rents and leases, or otherwise) of the
address of such Mortgagee or ground lessor. Tenant further agrees that if
Landlord shall have failed to cure such default within the time provided for in
this Lease, then the Mortgagee or ground lessor shall have an additional thirty
(30) days after receipt of notice thereof within which to cure such default or
if such default cannot be cured within that time, then such additional time as
may be necessary, if, within such thirty (30) days, any Mortgagee or ground
lessor has commenced and is diligently pursuing the remedies necessary to cure
such default (including but not limited to commencement of foreclosure
proceedings or other proceedings to acquire possession of the Real Property, if
necessary to effect such cure). Such period of time shall be extended by any
period within which such Mortgagee or ground lessor is prevented from commencing
or pursuing such foreclosure proceedings or other proceedings to acquire
possession of the Real Property by reason of Landlord's bankruptcy. Until the
time allowed as aforesaid for Mortgagee or ground lessor to cure such defaults
has expired without cure, Tenant shall have no right to, and shall not,
terminate this Lease on account of default. This Lease may not be modified or
amended so as to reduce the rent or shorten the term, or so as to adversely
affect in any other respect to any material extent the rights of the Landlord,
nor shall this Lease be canceled or surrendered, without the prior written
consent, in each instance, of the ground lessor or the Mortgagee.

the Act and all rules, regulations, ordinances, opinions, orders and directives
issued or promulgated pursuant to or in connection with said Act by the
Department of Environmental Protection ("DEP") related in any way to Tenant's
use and occupancy of the Premises. (The Act and all said rules, regulations,
ordinances, opinions, orders and directives are hereinafter collectively
referred to as "ISRA"). Without limiting the foregoing, upon Landlord's request
therefor, and in all events no later than sixty (60) days prior to "closing,
terminating or transferring operations" (as said terms are

                                       48




defined in ISRA) which would be subject to an obligation to comply with ISRA if
an industrial establishment is present at the Premises, Tenant, at its sole cost
and expense, shall provide the Landlord with a true copy of:



                  (A) an non-applicability letter from DEP (or such other agency
or body which shall then have jurisdiction over ISRA matters) in form
satisfactory to Landlord's counsel, stating that ISRA does not apply to Tenant,
Tenant's use and occupancy of the Premises and to the closing, terminating or
transferring of Tenant's operations at the Premises; or



                  (B) a Negative Declaration (as said term is defined in ISRA)
duly approved by DEP (or such other agency or body then having jurisdiction over
ISRA matters); or



                  (C) a Remedial Action Workplan (as said term is defined in

ISRA) duly approved by DEP (or such other agency or body which shall then have
jurisdiction over ISRA matters).


                  (iii) Nothing contained in this Section shall be construed as
limiting Tenant's obligation to otherwise comply with ISRA as aforesaid.



                  (iv) In the event Tenant complies with subparagraph (a) (ii)
of this Section 26.17 by obtaining an approved Remedial Action Workplan, Tenant
agrees that it shall, at its sole cost and expense:



                           (A) post any financial guarantee or other assurance

Workplan; and


                           (B) promptly implement and diligently prosecute to
completion said Remedial Action Workplan in accordance with the schedule
contained therein or as may otherwise be ordered or directed by DEP or such
other agency or body which shall then have jurisdiction over such Remedial
Action Workplan. Tenant expressly understands, acknowledges and agrees that
Tenant's compliance with the provisions of this subparagraph (iv) may require

                                      49




Tenant to expend or do acts after the expiration or termination of the Term and
Tenant shall not be excused therefrom. Any remediation conducted at the Premises
by Tenant under ISRA or otherwise shall be to the standard applicable to ISRA
related to the Premises and shall not involve alternative standards,
institutional or engineering controls.



                  (v) Within ten (10) days after a written request by the
Landlord or any Mortgagee, Tenant shall deliver to Landlord and the Mortgagee,
if any, a duly executed and acknowledged affidavit of Tenant's chief executive
officer, certifying:


                           (A) the proper four digit Standard Industrial
Classification Number relating to Tenant's then current use of the Premises
(Standard Industrial Classification Number to be obtained by reference to the
then current Standard Industrial Classification manual prepared and published by
the Executive Office of the President, Office of Management and Budget or the
successor to such publication); and




                           (B) (i) that Tenant's then current use of the
Premises does not involve the generation, manufacture, refining, transportation,
treatment, storage, handling or disposal of Hazardous Material on the site,
above ground or below ground, or (ii) that Tenant's then current use does
involve the presence of Hazardous Material, in which event, said affidavit shall
describe in complete detail Tenant's operations which involves the presence of
Hazardous Material. Such description shall, inter alia, identify each Hazardous
Material and describe the manner in which Tenant generated, handled,
manufactured, refined, transported, treated, stored, and/or disposed of same.
Tenant shall supply Landlord and the Mortgagee, if any, with such additional
information relating to the presence of Hazardous Material as Landlord or its
Mortgagee reasonably requests (nothing contained in this subsection (B) shall be
deemed or construed to permit Tenant to use Hazardous Material).

indemnify and hold Landlord harmless from and against any and all liability,
penalty, loss, expenses, damages,


                                       50





costs, claims, causes of action, judgments and/or the like, of whatever nature,
including but not limited to attorney's fees and other costs of litigation or
preparation therefor, to the extent such costs arise from or in connection with
Tenant's failure or inability, for any reason whatsoever, to observe or comply
with ISRA and/or provisions of this subparagraph 26.17(a).



                  (vii) Tenant agrees that each and every provision of this
paragraph 26.17(a) shall survive the expiration or early termination of the
Term. The parties hereto expressly acknowledge and agree that the Landlord would
not enter into this Lease but for the provisions of this subparagraph 26.17(a)
and the aforesaid survival thereof.



         (b) (i) Tenant agrees that it shall, at its sole cost and expense,
observe, comply and fulfill all of the terms and provisions of the Spill

amended from time to time (the "Act") and all rules, regulations, ordinances,
opinions, orders and directives issued or promulgated pursuant to or in
connection with said Act by DEP, any subdivision or bureau thereof or
governmental or quasi-governmental agency or body having jurisdiction thereof
(said Act and all said rules, regulations, ordinances, opinions, orders and
directives are hereinafter in this subparagraph 26.17 (b) collectively referred
to as "Spill Act") .



(ii) Without limiting the foregoing, the Tenant agrees:



                                    (A) that it shall not do, omit to do or
suffer the commission or omission of any act which is prohibited by or may
result in any liability under the Spill Act including without limitation the
discharge of petroleum products or other hazardous substances (as said terms are
defined in the Spill Act); and



                                    (B) whenever the Spill Act requires the
"owner or operator" to do any act, Tenant shall do such act and fulfill all such
obligations at its sole cost and expense, it being the intention of the parties
hereto that Landlord shall be free of all expenses and obligations arising from
or in connection with compliance with the Spill Act based on Tenants actions
and/or non compliance.


                                       51




                                    (iii) without limiting the foregoing, Tenant
agrees:



                                    (A) at its sole cost and expense, to
promptly discharge and to remove any lien or any encumbrance against the
Premises, or any other property owned or controlled, in whole or in part, by
Landlord, imposed by Tenant' failure to comply with the Spill Act; and



                                    (B) to defend (with counsel approved by
Landlord), indemnify and hold Landlord harmless from and against any and all
liability, penalty, loss, expenses, damages, costs, claims, causes of action,
judgments and/or the like, of whatever nature, including but not limited to
attorneys' fees and other expenses of litigation or preparation therefor, to the
extent such costs arise from or in connection with Tenant's failure or

inability, for any reason whatsoever, to observe or comply with the Spill Act
and/or the provisions of this subparagraph 26.17(b).



                           (iv) Tenant agrees that each and every provision of
this subparagraph 26.17(b) shall survive the expiration or earlier termination
of the Term. The parties hereto expressly agree and acknowledge that the
Landlord would not enter into this Lease but for the provisions of this
subparagraph 26.17(b) and the aforesaid survival thereof.



                  (c) (i) Tenant agrees that it shall, at its sole cost and
expense, promptly comply with all Environmental Laws applicable to its business
and properties, wheresoever located, or the Premises. Without limiting the
foregoing, Tenant agrees:



                                    (A) that it shall not allow to occur any
action or omission which is prohibited by or may result in any liability under
any Environmental Law;



                                    (B) whenever any Environmental Law requires
any action of either or both of the owner or operator of the Premises, Tenant
shall fulfill all such obligations at its sole cost and expense as relates to
Tenants use and/or operations of its business in the Premises, it being the
intention of the parties hereto that the Landlord shall be free of all expenses
or obligations arising from or in connection with compliance with any
Environmental

                                       52




Law and Tenant shall bear all such expenses and obligations as if it is the sole
owner and operator of the Premises as relates to Tenants use and/or operations
of its business in the Premises.



                           (ii) Without limiting the foregoing, Tenant agrees:

                                    (A) at its sole cost and expense to promptly

the Landlord or any mortgagee of the Landlord, Tenant shall deliver to Landlord
and Landlord's mortgagee, if any, a fully executed acknowledged affidavit of

                              ARTICLE TWENTY-SEVEN
                                     PARKING


27.01 Without additional charges of any kind therefor, Tenant, its employees,
agents, and invitees shall be entitled to use of the unreserved parking area
adjoining the Building, subject to reasonable rules and regulations, during the
term of the Lease, in common with others.

                              ARTICLE TWENTY-EIGHT
                          TENANT'S RIGHT OF FIRST OFFER

     Upon condition that Tenant is not in default in any of the payment of any
rent or other charge payable by Tenant under this Lease and not in default in
the performance of any covenant or obligation to be performed by Tenant under
this Lease and further subject to the conditions and limits hereinafter set
forth, Landlord agrees that Landlord will not enter into any new lease of any
unit of space in the second floor of that certain centerpod portion of the
Building (as shaded on Exhibit "A") of which the Premises are a part which may
become vacant during the initial term of this Lease with any tenant unless
Landlord shall first offer, in writing, said space to Tenant on such terms and
conditions as are then acceptable to the Landlord. Landlord agrees that Tenant
shall thereupon have the one-time right to lease said space in accordance with
the terms contained in Landlord's written notice. Said right must be exercised
by Tenant within twenty (20) business days after Tenant's receipt of written
notice of said offer by Tenant's giving written notice to Landlord of the
exercise of said right. If Tenant shall fail to exercise its right hereunder,
then Tenant shall execute in recordable form a release of its right to first
offer herein granted as applicable to the space so offered to Tenant. This right
of first offer (i) is not assignable and shall be deemed personal only to
Professional Detailing, Inc.; (ii) will not apply to any space to be leased by
Landlord to a tenant at that time leasing other space in the Building; (iii) is
limited to the exercise of rights for space only once, and once offered and
declined all rights to lease the particular offered space shall cease and
terminate, however the right to lease other space not yet offered shall continue
to exist.

The following additional items shall apply to said Right of First Offer:

(i) Tenant's right to add space to the Premises under this Article 28 shall be
exercised by the notice to Landlord containing Tenant's election for the entire
amount of offered space;

                                       54





(ii) The added space shall become a part of the Premises and except for such
terms contained in the notice from Landlord the terms and conditions of this
Lease, including, but not limited to, the Lease Term and options shall be
applicable thereto.

(iii) Once the size of the added space has been determined this Lease and
Exhibit "A" shall be appropriately revised to reflect the revised payments and
Premises including the added space, signed and initialled by Landlord and Tenant

and added to or attached to this Lease as applicable.

(iv) Said right of first offer shall be subject to any other rights, similar or
dissimilar, granted by Landlord heretofore as set forth on Exhibit "G" attached
hereto and by this reference made a part hereof.

                               ARTICLE TWENTY-NINE
                                 RENEWAL OPTION;


29.01 (a)By written notice delivered to Landlord on or before the date which is
twelve (12) months prior to the expiration of the term of this Lease (the
"Exercise Date"), time being of the essence, expressly provided that Tenant is
not in default in any respect under the terms of this Lease beyond any
applicable notice and grace period on (i) the Exercise Date and (ii) the last
day of the term of this Lease (the "Expiration Date"), Tenant shall have the
option to extend the term of this Lease for five (5) years commencing on the
first day following the Expiration Date and ending on the date which is five (5)
years thereafter (hereinafter called the "Renewal Term") upon the same terms and
conditions hereof except that the Monthly Base Rent to be paid by Tenant for the
Renewal Term shall be then annual fair market rental value for the Premises, as
determined as hereinafter set forth, and to be effective on the first day of the
Renewal Term. In this regard, no earlier than three hundred thirty (330) days
and no later than three hundred (300) days prior to the Expiration Date, which
thirty (30) day period is hereinafter referred to as the "Exchange Period",
Landlord shall submit to Tenant a statement of Landlord's determination of the
annual fair market rental value for the Premises for the Renewal Term, which
statement shall show the basis upon which such determination was made.
Landlord's determination of the annual fair market rental value shall give due
consideration to the rents (including any concessions, tenant finish allowances
or related matters) charged by Landlord for all leases of comparably sized space
(excluding exercise of renewal rights where the tenant had a right of renewal
under the terms of its lease) entered into by Landlord for the twelve (12) month
period preceding the first day of the Exchange Period, except that if there were
no such leases or such leases were so peculiar to a particular situation that no
true comparables would be derived, Landlord may expand the basis of its
determination to include the rents being charged by other owners of comparable
first class office buildings located in the Northern Bergen County, New Jersey.
Within thirty (30) days after receipt of Landlord's determination, Tenant may
either (i) rescind the exercise of its option, (ii) accept Landlord's
determination of the annual fair market rental value or (iii) provide Landlord
with its own determination of the annual fair market rental value, including the
basis upon which such determination was made.


                                       55





If Tenant elects option (iii), then Landlord and Tenant shall, for a period of
thirty (30) days after Landlord's receipt of Tenant's determination, negotiate
in good faith to determine the annual fair market rental value and if Landlord

and Tenant are unsuccessful in reaching agreement within such thirty (30) days,
Tenant may cause the issue arbitrated as hereinafter in this Article 29 set
forth. If Tenant does not elect to have the issue arbitrated as hereinafter in
this Article 29 set forth, this option to renew shall automatically be null and
void and of no force or effect five (5) days following the thirty (30) day
period following Landlord's receipt of Tenant's determination of the annual fair
market rental value. Except for the Monthly Base Rent, the Renewal Term shall be
upon all of the terms, covenants and conditions contained in this Lease.

   (b) In the event Tenant elect's to arbitrate the issue of annual fair market
rental value, such issue shall be determined by arbitration as hereinafter
provided. Landlord and Tenant shall each appoint a fit and impartial person as
an arbitrator who shall have at least ten (10) years' experience in the
commercial real estate industry in the Saddle River, New Jersey area (a
"Qualified Arbitrator"). Such appointment shall be indicated in writing by each
party to the other within ten (10) days following the thirty (30) day period
following Landlord's receipt of Tenant's determination of the annual fair market
rental value, as aforesaid. If the arbitrators are unable to determine the
annual fair market rental value as set forth below within twenty (20) days of
their appointment, the arbitrators so appointed shall immediately appoint a
third Qualified Arbitrator. In case either party shall fail to appoint a
Qualified Arbitrator within a period of ten (10) business days after written
notice form the other party to make such appointment, the American Arbitration
Association, or its successor (the "AAA") shall appoint such Qualified
Arbitrator(s). The two (2) arbitrators so appointed shall appoint the third
(3rd) arbitrator, as aforesaid, otherwise the AAA shall similarly make such
appointment. The arbitrators shall proceed with all reasonable dispatch to
determine the annual fair market rental value and under all circumstances shall
be bound by the terms of this Lease and shall not add to, subtract from, or
otherwise modify such provisions, provided, however, the arbitrators shall take
into account all relevant factors in determining the annual fair market rental
value. The concurrence of any two said arbitrators shall be binding upon
Landlord and Tenant, or, in the vent no two of the arbitrators shall render a
concurrent determination, then the determination of the third (3rd) arbitrator
shall be binding upon Landlord and Tenant. The determination of such third (3rd)
arbitrator shall be no higher than Landlord's arbitrator's determination, and no
lower than Tenant's arbitrator's determination. The decision of the arbitrators
shall, in any event, be rendered within thirty (30) days after the appointment
of the first and second arbitrators and such decision shall be in writing and in
duplicate with one counterpart delivered to each Landlord and Tenant. The
arbitration shall be conducted in accordance with the rules of the AAA and
applicable New Jersey law, and a decision of a majority of the arbitrators shall
be binding, final conclusive upon Landlord and Tenant. The fees of the
arbitrators and the expenses incident to the proceedings shall be shared equally
between Landlord and Tenant.

(c) Once the option period rent is determined as set forth, Tenant shall
commence paying the same as of the first day of the option period.


                                       56
