    SECTION 4. CONSTRUCTION OF PREMISES

    4.1. COMPLETION OF BUILDING. Landlord will construct on the Center the 
Building in which the Premises are to be located, or cause it to be 
constructed, as promptly as possible, subject to conditions constituting 
force majeure, or other causes beyond Landlord's reasonable control. In 
addition, Landlord shall, at its cost and expense, construct the Premises for 
Tenant's use and occupancy in accordance with plans and specifications 
prepared by Landlord or Landlord's architect, in the following manner. Within 
ten (10) days from the date of the execution of this Agreement. Tenant shall 
provide Landlord with Final Plans and Specifications (the "Final Plans and 
Specifications") prepared by a professional designer, interior designer, or 
architect, approved by Landlord in advance, for the layout of the Leased 
Premises, including the dimensioned location of all partitions, interior 
doors, lighting fixtures, lightpole switches, electrical outlets, telephone 
receptacles or systems, together with the specifications therefor and any 
other improvements Tenant desires to be made thereto prior to the 
commencement of the term of this Lease. If Tenant fails to submit the Final 
Plans and Specifications within ten (10) days after the execution of this 
Lease then Tenant shall be assessed a penalty equivalent to the one-thirtieth 
of the monthly installment of Basic Rent as set forth under Subsection 1.6 of 
this Lease for each day late. Upon completion, the Final Plans and 
Specifications shall be submitted to Landlord for its review and approval. 
The Final Plans and Specifications shall be substantially in the form of the 
Preliminary Plans and Specifications (the "Preliminary Plans and 
Specifications") attached hereto on Exhibit "B". The parties acknowledge and 
agree that the Basic Rent set forth in Subsection 1.6 incorporates the 
parties' best estimate, based upon the Preliminary Plans and Specifications 
and, as of the date of this Lease, of the cost of completion of Leasehold 
Improvements, and that such estimate may differ from the actual cost 
calculated with reference to the Final Plans and Specifications. Accordingly, 
Landlord shall have the right to adjust the Basic Rent to reflect of the 
cost to complete the modified improvements based upon the Final Plans and 
Specifications.

    Landlord shall notify Tenant of such adjustment, if any, at the time 
Landlord notifies Tenant of Landlord's approval of the Final Plans and 
Specifications. Tenant shall have five (5) days (not counting any intervening 
Saturday or Sunday) to approve or disapprove Landlord's adjustment to Basic 
Rent, if any, and shall be deemed to have accepted and approved the 
adjustment to Basic Rent, if any, unless Tenant shall have notified Landlord 
to the contrary, in writing, in accordance with Section 25 of this Lease, 
within such five (5) day period. If Tenant fails to accept the Landlord's 
adjustment to Basic Rent within such five (5) day period, then Landlord 
shall, at its sole option and discretion, have the right to declare this 
Agreement null and void and of no further force and effect. If, however, 
Tenant accepts the adjustment to Basic Rent, if any, whether by express 
letter of acceptance given within such five (5) day

                                      -3-                                     



period or by failure to reject the same within such five (5) day period, then 
Tenant agrees to execute and acknowledge such instruments confirming such 
acceptance as Landlord may from time to time require. Upon Tenant's 
acceptance of the adjustment to Basic Rent, if any, in the manner herein 
described, Landlord shall construct or cause to be constructed all of the 
Leasehold Improvements required by the Final Plans and Specifications. Upon 
taking possession and occupying the Leased Premises, Tenant shall thereby be 
deemed to have accepted the same and to have acknowledged that the Leased 
Premises are in the condition called for hereunder and under the Final Plans 
and Specifications. Under no circumstances shall Landlord be liable to Tenant 
for damages for any delay in commencing or completing construction of the 
Premises or for a total failure to complete or deliver the same.

    4.2. RIGHT OF CANCELLATION. Anything herein to the contrary 
notwithstanding, if for any reason the Term of this Lease shall not have 
commenced within one (1) year from the date of this Lease then either party 
shall have the right and option to terminate this Lease by written notice to 
the other, whereupon, effective with the giving of such notice, this Lease 
shall be cancelled and neither party shall have any liability arising 
hereunder, except that Landlord shall return any sum deposited by Tenant 
pursuant to Subsection 1.9 hereof, plus any interest accrued if monies were 
held in an interest bearing checking account.

    4.3. ACCEPTANCE OF PREMISES. By opening for business, Tenant shall be 
deemed to have accepted the Premises, to have acknowledged that they are in 
the condition called for hereunder and to have agreed that the obligations of 
Landlord imposed for the delivery of the Premises have been fully performed. 
Landlord agrees to assign for the benefit of Tenant such warranties as may be 
available from Landlord's contractors with respect to Landlord's work in the 
construction of the Premises.

    SECTION 5. RENT. Tenant covenants and agrees to pay to Landlord during 
the Term, as Rent for the Premises, the following.

    5.1 BASIC RENT. The Basic Rent shall be payable in equal monthly 
installments in advance on the first day of each full calendar month during 
the Term, without any deduction or setoff whatsoever, and without demand. The 
first monthly payment shall include any prorated Basic Rent for the period 
from the date of the commencement of the Term to the first day of the first 
full calendar month.

    5.2 DEPOSIT. Landlord hereby acknowledges receipt from Tenant of the 
Deposit. In no instance shall the amount of such Deposit be considered a 
measure of liquidated damages. All or any part of the Deposit may be applied 
by Landlord in total or partial satisfaction of any default by Tenant. The 
application of all or any part of the Deposit to any obligation or default of 
Tenant under this Lease shall not deprive

                                      -4-                                     



Landlord of any other rights or remedies Landlord may have nor shall such 
application by Landlord constitute a waiver by Landlord. If all or any part 
of the Deposit is applied to an obligation of Tenant under this Agreement 
then Landlord shall have the right to call upon Tenant to restore the Deposit 
to its original amount by giving notice to Tenant and Tenant shall 
immediately restore the Deposit by payment thereof to Landlord. The Deposit 
shall be held by Landlord without liability for interest; Landlord shall be 
entitled to the full use of the Deposit and shall not be required to keep it 
in a segregated account or escrow. It is understood and agreed that should 
Landlord convey its interest under this Lease, the Deposit may be turned over 
by Landlord to Landlord's grantee or transferee, and upon any such delivery 
of the Deposit, Tenant hereby releases Landlord herein named of any and all 
liability with respect to the Deposit, its application and return, and Tenant 
agrees to look solely to such grantee or transferee, and it is further 
understood that this provision shall also apply to subsequent grantees and 
transferees. Landlord will return the balance of the Deposit not previously 
applied as provided herein, within thirty (30) days after expiration of the 
Term, plus any interest accrued if monies were held in an interest bearing 
account.

    5.3. REAL ESTATE TAXES. Landlord shall pay all Taxes levied upon or 
assessed against the land and improvements comprising the Center and the 
appurtenances thereto during the Term of this Lease. If the Taxes payable by 
Landlord are increased in any Tax Year during the Term of this Lease over the 
amount of such Taxes due and payable with respect to the Center for the Tax 
Tear in effect as of the Commencement of this Lease, then Tenant shall pay to 
Landlord, as Additional Rent, its Proportionate Share of such Tax increase. 
The term "Taxes" shall be defined as (i) all real estate and other ad 
valorem taxes, including, without limitation, real estate rental, receipt or 
gross receipt tax or any other tax on Landlord (excluding Landlord's income 
taxes), now or hereafter imposed by any federal, state or local taxing 
authority and whether as a substitution for or in addition to the present 
method of real property taxation currently in use; (ii) costs of attorney's 
and appraiser's fees, if necessary, incurred in connection with any 
negotiation, contest or appeal pursued by Landlord in an effort to reduce 
taxes, and (iii) any metropolitan district water and sewer charges and other 
governmental charges which customarily are part of the real estate tax bill 
issued by governmental authorities charged with said responsibility.

    Taxes shall be adjusted on a proportionate basis for any period which 
shall be less than a Tax Year. The Tax Year shall be the year so established 
by the governmental authority charged with that responsibility. Landlord 
agrees to provide Tenant with a copy of the Tax bill and the calculation of 
Tenant's share thereof within a reasonable time. Tenant agrees to pay its 
Proportionate Share of any increase in Taxes above the amount of Taxes due 
and payable during the Tax Year in effect as of the commencement of the Term. 
Tenant shall pay such Proportionate Share of Taxes within thirty (30) days 
after written request therefor by Landlord, and further agrees, in lieu 
thereof, at the prior request and 

                                    -5-


election of Landlord, to pay the same in equal monthly installments in such 
amounts as are estimated and billed for each Tax Year by Landlord at the 
commencement of the Term and at the beginning of each successive Tax Year, 
with appropriate adjustment being made at the end of each Tax Year.

    5.4. COMMON AREA EXPENSE. During each Lease Year of this Lease, and during 
any Lease Year of any renewal term hereof, Tenant will pay to Landlord its 
Proportionate Share of Common Area Expense, at the time and in the manner 
provided in the last sentence of Section 5.3 hereof. "Common Area Expense" 
means the total cost and expense, including reasonable administrative charges 
and overhead, incurred by Landlord in the operation, maintenance and repair 
of common areas of the Center and all areas, space, equipment, facilities and 
improvements thereon and services therein, including, but not by way of 
limitation, the operation of the areas and services described in Sections 7 
and 10 hereof.

    5.5. ADDITIONAL RENT. Tenant's liability for its Proportionate Share of 
the expenses described in Subsections 5.3 and 5.4 hereof, together with any 
other charges due and payable from Tenant as set forth in the Lease, shall be 
deemed Additional Rent.

    5.6. ADJUSTMENT OF PROPORTIONATE SHARE. If Landlord, in Landlord's sole 
discretion, elects to construct one or more additional buildings ("Additional 
Building") within the Center, Landlord shall have the right, by written 
notice to Tenant, to adjust Tenant's Proportionate Share. The adjustment 
shall be made by adding to the Rentable Area of the Building the rentable 
area of any Additional Building upon substantial completion thereof, and by 
dividing the total by the Rentable Area of the Premises. Appropriate 
proration shall be made for any partial period of a Lease Year resulting from 
such adjustment.

    5.7. LATE CHARGE FOR FAILURE TO PAY RENT AND ADDITIONAL RENT. If Tenant 
fails to pay any Basic Rent or any Additional Rent within ten (10) days of 
the time it is due and payable then Landlord, in addition to all other rights 
and remedies contained in this Lease, may assess a one-time late charge 
against Tenant at a rate of five percent (5%) of the delinquent rental 
payment and such unpaid amounts shall bear interest from the due date thereof 
to the date of payment at a rate of twelve percent (12%) per annum. Tenant 
shall further be responsible for the payment of any reasonable legal expense 
and management fees incurred by Landlord in collecting any delinquent Rent 
due hereunder.

    5.8. ALL CHARGES CONSTITUTE RENT. Notwithstanding anything in this Lease 
to the contrary, all amounts payable by Tenant to or on behalf of Landlord 
under this Lease, whether or not expressly denominated as Basic Rent or 
Additional Rent, and including any and all advances, charges, costs or fees 
incurred by Landlord in collecting any sums due from Tenant hereunder, or 
otherwise in preserving the rights of

                                    -6-


Landlord hereunder or in enforcing the rights and obligations of Landlord and 
Tenant hereunder, (and specifically including legal expenses and management 
fees incurred by Landlord hereunder) shall constitute and shall be referred 
to as "Rent" for the purposes of this Lease as well as Section 502(b)(6) of 
the Bankruptcy Code, 11 U.S.C. section 502(b)(6).

    SECTION 6. PERMITTED USE AND CONTINUED OCCUPANCY. The Premises shall be 
used and occupied for the Permitted Use and for no other use or purpose. 
Furthermore, the premises shall not be used in any way which may violate any 
certificate of occupancy or other governmental requirements or restrictions 
of record.

    SECTION 7. COMMON AREAS. During the Term of this Lease Tenant shall be 
entitled to the non-exclusive use, free of charge, but in common with others, 
of the driveways, footways, and parking areas presently existing, provided 
that such use shall be subject to such reasonable rules and regulations as 
Landlord may from time to time prescribe; and provided further, that Landlord 
shall at all times have full and exclusive control, management and direction 
of the driveways, footways, and parking areas. Landlord shall further have 
the right to police them, to restrict parking by Tenants, their officers, 
agents, employees, contractors and invitees; to close temporarily all or any 
portion of the parking areas of facilities as may be required for proper 
maintenance and/or repair; to discourage non-customer parking; and to do and 
perform such other acts in and to such areas as, in the use of its business 
judgment, Landlord shall determine to be advisable in order to improve or 
make more convenient the use thereof by tenants, their officers, agents, 
employees and customers. Landlord may from time to time change the location, 
layout and arrangement of the parking areas, driveways, and footways and 
reduce them by erecting thereon buildings or other structures or improvements 
of any kind including, but not limited to, extensions to the Center; provided 
that the convenience of parking facilities available to Tenant shall not be 
substantially prejudiced thereby; and provided further that there shall at 
all times be provided such parking facilities as meet local governmental 
requirements. Landlord shall provide reasonable illumination for the 
driveways, footways and parking areas, and will keep them in reasonable 
repair and reasonably free of litter and snow.

    SECTION 8. ASSIGNMENT AND SUBLETTING. Tenant shall not assign, mortgage 
or encumber this Lease, in whole or in part, nor sublease all or any part of 
the Premises, nor permit other persons to occupy the Premises or any part 
thereof, nor grant any license or concession for all or any part of the 
Premises, without the prior written consent of Landlord in each instance, 
whose consent shall not be unreasonably withheld. Any consent by Landlord to 
an assignment or subletting of this Lease shall not constitute a waiver of 
the necessity of such consent as to any

                                    -7-


subsequent assignment or subletting and shall not relieve Tenant of liability 
hereunder. An assignment for the benefit of Tenant's creditors or otherwise 
by operation of law shall not be effective to transfer or assign Tenant's 
interest under this Lease unless Landlord shall have first consented thereto 
in writing. If any partnership interest or corporate shares of stock of 
Tenant are transferred by sale, assignment, bequest, inheritance, operation 
of law or otherwise, so as to result in a change of the voting control of 
Tenant by those owning a majority of the partnership interest or corporate 
shares of Tenant as of the date hereof, Tenant shall so notify Landlord of 
said change. Landlord may terminate this Lease at any time after any such 
change of control by giving Tenant ninety (90) days prior written notice 
thereof, but such cancellation shall not relieve Tenant of liability 
hereunder. If this Lease is assigned to any person or entity pursuant to the 
provisions of the Bankruptcy Code, 11 U.S.C. section 101, ET SEQ. (the 
"Bankruptcy Code"), any and all monies or other considerations payable or 
otherwise to be delivered in connection with such assignment shall be paid or 
delivered to Landlord, shall be and remain the exclusive property of Landlord 
and shall not constitute property of Tenant or of the Estate of Tenant within 
the meaning of the Bankruptcy Code. All monies or other considerations 
constituting Landlord's property under the preceding sentence not paid or 
delivered to Landlord shall be held in trust for the benefit of Landlord and 
be promptly paid or delivered to Landlord.

    SECTION 9. REPAIRS.

    9.1. EXTERIOR REPAIRS. Landlord shall keep and maintain the roof and other 
exterior portions of the Premises (exclusive of doors, windows, and glass) in 
repair, provided that Tenant shall give Landlord written notice of the 
necessity for such repairs, and provided that the damage thereto shall not 
have been caused by Tenant, its agents, contractors, or employees, in which 
event Tenant shall be responsible therefor and shall promptly repair it. 
Except as expressly set forth in this Subsection 9.1, Landlord shall be under 
no liability for repair or maintenance of the Premises, or any part thereof; 
nor shall Landlord be under any liability to repair or maintain any 
electrical, plumbing, heating, air conditioning or other mechanical 
installations or equipment.

    9.2. INTERIOR REPAIRS. Tenant shall keep the interior of the Premises, 
together with all electrical, plumbing, heating, air conditioning and other 
mechanical installations and equipment used by or in connection with the 
Premises, in good order, replacement and repair, and promptly replace any 
plate glass which may be broken or damaged with glass of like kind and 
quality, and surrender the Premises at the expiration of the Term in as good 
condition as when received except for ordinary wear and tear and damage by 
fire or other casualty included in the extended coverage endorsement to 
Landlord's fire insurance policies. Tenant will not overload the electrical 
wiring and will not install any additional electrical 

                                    -8-




wiring or plumbing unless it has first obtained Landlord's written consent 
thereto, and, if such consent is given, Tenant will install them at its own  
cost and expense. Tenant will repair promptly, at its own expense, any damage 
to the Premises caused by bringing into the Premises any property for 
Tenant's use, or by the installation, use or removal of such property, 
regardless of fault or by whom such damage shall be caused unless caused by 
Landlord, its agents, employees or contractors. In furtherance of Tenants 
obligations, Tenant covenants and agrees to obtain a maintenance, repair and 
service contract on the HVAC system, such contract to be on such terms and 
with such company as shall be approved reasonably by Landlord and delivered 
to Landlord within thirty (30) days after commencement of the Term. Landlord 
shall transfer all warranties on electrical, plumbing, HVAC and other 
mechanical equipment.

    9.3.  LANDLORD'S RIGHT TO REPAIR. If Tenant does not proceed promptly and 
diligently to make any repairs or perform any obligation imposed upon it by 
the preceding subsections within forty-eight (48) hours after receiving 
written notice from Landlord to make such repairs or perform such obligation, 
then Landlord may, at its option, enter the Premises and do and perform the 
things specified in the notice, without liability on the part of Landlord for 
any loss or damage resulting from any such action by Landlord, and Tenant 
agrees to pay promptly upon demand any cost or expense incurred by Landlord 
in taking such action. Landlord agrees, after written notice from Tenant, to 
make those repairs required of it under this Lease and to perform its 
obligations hereunder as promptly as reasonably possible under the 
circumstances.

    SECTION 10. UTILITIES. Tenant shall reimburse Landlord upon demand for 
Tenant's Proportionate Share of all utility charges for the Center not billed 
directly to Tenant. Tenant shall pay the charges for all utility services 
billed directly to Tenant promptly when due, including but without 
limitation, heat, electricity and telephone. If Tenant defaults in the 
payment of any such charges, Landlord may, at its option, pay them for 
Tenant's account, in which case Tenant shall promptly reimburse Landlord 
therefor. Landlord will provide and maintain the necessary mains and 
electrical conduits to bring water and electricity to the Premises. Landlord 
shall under no circumstances be liable to Tenant in damages or otherwise for 
any interruption in service of electricity, water, heat, telephone or air 
conditioning whether caused by the making of any repairs or improvements in 
the Building or otherwise. The cost of installing any meters, where necessary 
to measure Tenant's consumption of said utilities, shall be at Tenant's 
expense.

    SECTION 11. COMPLIANCE WITH RULES, ORDINANCES, ETC. Tenant shall, 
throughout the Term, at Tenant's sole cost and expense, promptly comply with 
all laws, ordinances, notices, orders, rules, regulations and requirements of 
or made by any and all federal, state or municipal governments of the 
appropriate departments, commissions, boards and officers thereof, as well as 
any and all notices, orders, rules and

                                      -9-


regulations of the National Board of Fire Underwriters, or any other body now 
or hereafter constituted and exercising similar functions, relating to all or 
any part of the Premises; provided, however, that Tenant shall not be 
required to take any affirmative action in order to comply with the 
foregoing laws, ordinances and notices with respect to the exterior of any 
portion of the Building other than the Premises unless the need for such 
compliance arises out of Tenant's use, manner of use or occupancy of, or 
installations within or upon, the Premises or such portion of the Building. 
Tenant shall likewise observe and comply with the requirements imposed by any 
and all policies of public liability, fire and other insurance at any time in 
force with respect to the Premises or with respect to the Building, any other 
improvements upon the Premises, and/or equipment therein. Tenant shall comply 
with the National Fire Code which prohibits smoking in storage areas 
containing combustible products and shall install, at its expense, "No 
Smoking" signs in those areas of the Premises. Tenant shall also install fire 
extinguishers throughout the Premises and shall inspect such extinguishers at 
least once a year and refill and maintain such extinguishers as often as 
necessary. Tenant shall also comply with Landlord's rules and regulations 
attached hereto as Exhibit C.

    SECTION 12. TENANT'S ALTERATIONS. Tenant shall not paint or decorate, or 
make any alterations, additions or improvements to the Building or to the 
Premises, or any part thereof, without Landlord's prior written consent in 
each instance which consent shall not be unreasonably withheld. Tenant shall 
present plans and specifications for such work to Landlord at the time 
approval is sought. Before making any alterations, additions, installations, 
or improvements Tenant shall, at its expense, obtain all permits, approvals 
and certificates required by governmental authorities and, upon completion, 
certificates of final approval thereof, and shall deliver duplicates of all 
such permits, approvals and certificates to Landlord promptly thereafter. 
Tenant agrees to carry and will cause Tenant's contractors and subcontractors 
to carry such workmen's compensation, general liability, personal and 
property damage insurance as Landlord may require. Any alterations, additions 
or improvements made by Tenant constituting fixtures shall immediately become 
the property of Landlord and shall remain upon the Premises. Alternately, 
Landlord may elect to require Tenant to remove such alterations, additions 
and improvements and restore the Premises to their original condition, in 
which case Tenant shall comply with such requirement prior to the expiration 
or other termination of this Lease. Tenant shall not cut or drill into or 
secure any fixtures, apparatus or equipment of any kind in or to any part of 
the Premises without first obtaining Landlord's written consent. Tenant shall 
cause to be removed within ten (10) days after notice thereof any lien, 
including any mechanic's lien asserted against work performed upon the 
Premises. Tenant shall also defend on Landlord's behalf, at Tenant's sole 
cost and expense, any action, suit or proceeding for the enforcement of any 
such lien, and Tenant shall pay any damages and satisfy and discharge any 
judgment entered thereon and save Landlord harmless from any loss, liability, 
expense, including reasonable counsel fees, claims or damages resulting 
therefrom.

                                      -10-


    SECTION 13. INSURANCE.

    13.1. LIABILITY INSURANCE, ETC. Tenant, at Tenant's sole cost and 
expense, shall maintain and keep in effect throughout the Term, insurance 
against loss or liability in connection with bodily injury or death or 
property damage or destruction in or upon the Premises, or arising out of the 
use of any portion of the Center by Tenant or its agents, employees, 
officers, invitees, visitors and guests, under policies of general public 
liability insurance having such limits as to each as may be reasonably 
required by Landlord from time to time, but in any event of not less than One 
Million Dollars ($1,000,000) for each person and One Million Dollars 
($1,000,000) for each occurrence with respect to bodily injury or death, and 
One Hundred Thousand Dollars ($100,000) for each occurrence with respect to 
property damage or destruction. Such policies shall name Landlord, any other 
parties in interest designated by Landlord from time to time, and Tenant as 
the insured parties, shall provide that they shall not be cancellable without 
at least thirty (30) days prior written notice to Landlord, and shall be 
issued by insurers of recognized responsibility licensed to do business in 
Maryland. At least five (5) days prior to the commencement of the Term, the 
originals or a signed duplicate copy of such policies shall be delivered by 
Tenant to Landlord and at least thirty (30) days before any such policy shall 
expire Tenant shall deliver the original or a signed duplicate copy of a 
replacement policy to Landlord.

    13.2 FIRE AND EXTENDED COVERAGE. Landlord shall maintain throughout the 
Term all risk or fire and extended coverage insurance on the Building and may 
maintain all risk or fire and extended coverage insurance on the equipment, 
fixtures and other improvements installed and/or owned by Landlord and used 
in connection with the Building and/or the Center, and/or all alterations, 
rebuildings, replacements and additions thereto, including but not limited to, 
insurance insuring the same against loss or damage by, or abatement of rental 
income resulting from fire, and other such hazards, casualties and 
contingencies, liability and indemnity insurance (all of which are 
hereinafter referred to collectively as "Insurance Costs"). Tenant shall pay 
to Landlord, as Additional Rent hereunder, upon demand, the amount, if any, by 
which Landlord's premium shall be increased by reason of Tenant's occupancy 
of the Premises. If the dollar amount of premiums for Insurance Costs for any 
Lease Year while this Lease is in effect is greater than the dollar premiums 
for Insurance Costs for the year in which this Lease commences, Tenant shall 
pay to Landlord, as Additional Rent hereunder, upon demand, its Proportionate 
Share of such increase during the Lease Year in which such increase takes 
place and during each Lease Year thereafter.

    13.3 RELEASE. Each of the parties hereto hereby releases the other, to 
the extent of the releasing party's actual recovery under its insurance 
policies, from any and all liability for any loss or damage which may be 
inflicted upon the property of such party, even if such loss or damage shall 
have arisen out

                                       -11-


of the negligent or intentionally tortious act or omission of the other 
party, its agents or employees; provided, however, that this release shall 
be effective only with respect to loss or damage occurring during such time as 
the appropriate policy of insurance shall contain a clause to the effect that 
this release shall not affect the said policy or the right of the insured to 
recover thereunder.

    SECTION 14. CHANGES TO CENTER. Landlord shall have the exclusive right to 
use all or any part of the roof and rear and side walls of the Premises for 
any purpose; to erect additional or other structures over all or any part of 
the Premises or the Center; to change or revise the layout of improvements 
within the Center, or relocate or remove the same; to partition the same; and 
to erect and maintain in connection with the construction thereof temporary 
scaffolds and other aids to construction on the exterior of the Premises, 
provided that access to the interior of the Premises shall not be denied, 
that there shall be no encroachment upon the interior of the Premises, and 
that the use and enjoyment of the Premises by Tenant and its customers shall 
not be unreasonably denied.

    SECTION 15. FIRE OR OTHER CASUALTY.

    15.1. REPAIR OR DAMAGE. If the Premises are damaged by fire, the 
elements, unavoidable accident or other casualty, Landlord shall promptly at 
its expense repair the damage and if the Premises are not thereby rendered 
untenantable in whole or in part, rent shall not abate. If the Premises are 
rendered untenantable only in part, rent shall abate during such period 
proportionately as to the portion of the Premises rendered untenantable. If 
the entire Premises are untenantable, rent shall abate entirely during the 
period of untenantability.

    15.2. NO LIABILITY FOR INTERRUPTION TO BUSINESS. In no event shall 
Landlord be liable for interruption to Tenant's business or for damage to or 
replacement or repair of Tenant's personal property, including inventory, 
trade fixtures, floor coverings, furniture, property removable by Tenant 
under the provisions of this Lease or leasehold improvements.

    15.3. LANDLORD'S ELECTION TO TERMINATE LEASE. If the Premises are (i) 
rendered wholly untenantable, or (ii) damaged as a result of any cause which 
is not covered under standard fire and extended coverage insurance, or (iii) 
substantially damaged during the last two years of the Term, or if the 
Building of which the Premises are a part (but not the Premises), is damaged 
to the extent that, in Landlord's judgment, reasonably exercised, it is 
necessary to demolish the Building and the Premises, then in that case, 
Landlord may terminate this Lease by giving to Tenant notice within ninety 
(90) days after the

                                      -12- 


occurrence of such event. Basic Rent and Additional Rent and other charges 
shall be adjusted as of the date of such cancellation.

    SECTION 16. SIGNS. Tenant shall not erect or maintain any exterior sign 
or any signs within the Premises visible from the outside anywhere upon the 
Center or Premises without first obtaining Landlord's written approval as to 
the size, design, location, type of composition or material thereof. Design 
shall be in accordance with the guidelines established by Landlord from time 
to time. Any such sign shall be inscribed, painted or affixed by Landlord, or 
a company approved by Landlord, but the entire cost thereof shall be borne by 
Tenant. Tenant shall maintain any such sign or signs in good condition and 
repair at all times, and pay any taxes imposed thereon.

    SECTION 17. EMINENT DOMAIN. If the whole or any part of the Premises is 
taken under the power of eminent domain then this Lease shall terminate as to 
the part so taken on the date Tenant is required to yield possession thereof 
to the condemning authority. Landlord shall make necessary repairs and 
alterations to restore the part not taken to useful condition and the Basic 
Rent shall be reduced proportionately as to the portion of the Premises so 
taken. If the amount of the Premises so taken substantially impairs the 
usefulness of the Premises for the purposes set forth in Section 6, then 
either party may terminate this Lease as of the date when Tenant is required 
to yield possession. All compensation awarded for any taking of the fee and 
the leasehold shall belong to and be the property of Landlord; provided, 
however, that Tenant, and not Landlord, shall be entitled to any portion of 
the award which does not serve to reduce Landlord's award and is made 
directly to Tenant in reimbursement for Tenant's cost of removal of its 
stock, trade fixtures, moving and relocation costs.

    SECTION 18. TRADE FIXTURES. All trade fixtures installed by Tenant in the 
Premises, other than improvements made by Tenant to the Premises, shall 
remain the property of Tenant and shall be removable from time to time and 
also at the expiration of the Term of this Lease or other termination 
thereof, provided Tenant shall not at such time be in default under any 
covenant or agreement contained in this Lease; otherwise such fixtures shall 
not be removable, and Landlord shall have a lien thereon to secure itself 
against loss and damage resulting from such default. Tenant further agrees to 
restore the Premises to their original condition, fair wear and tear excepted.

    SECTION 19. RIGHT OF ENTRY. Landlord and its representatives shall have 
the right at all reasonable times to enter the Premises for the purposes of 
(a) inspecting them, (b) repairing them or otherwise performing any work 
therein as herein provided; and (c) exhibiting them for sale, lease or 
financing; and Landlord shall not be liable in any manner for any entry into 
the Premises for such purposes.

                                      -13-


    SECTION 20. SURRENDER. Promptly upon the expiration or earlier 
termination of the Term, Tenant shall yield up the Premises and any and all 
improvements, alterations and additions thereto, and all fixtures and 
equipment servicing the Premises, clean and neat, and in the same condition, 
order and repair in which they are required to be kept throughout the term of 
this Lease. Tenant shall remove its signs, goods and effects and machinery, 
fixtures and equipment used in the conduct of its trade or business and not 
servicing the Building, and shall repair any damage caused by the 
installation or the removal thereof. Unless sooner terminated pursuant to the 
provisions hereof, this Lease shall expire absolutely upon the expiration of 
the Term without the necessity of any notice or other action from or by 
either party hereto. Tenant further agrees that during the six (6) month 
period preceding the expiration date of the Term, Landlord may place upon the 
Premises a FOR RENT sign.

    SECTION 21. CURING THE TENANT'S DEFAULTS. If Tenant defaults in the 
performance of any of its obligations under this Lease then, in addition to 
any other rights it may have in law or equity, and after written notice to 
Tenant except in the case of emergency, Landlord shall be entitled (but shall 
not be obligated) to cure such default, and Tenant shall reimburse Landlord 
for any sums paid or costs incurred by Landlord, including reasonable 
attorney's fees, in curing such default, plus interest thereon at the lesser 
of the highest rate permitted by law or fifteen percent (15%) per annum, 
which sums, costs and interest shall be deemed to be Additional Rent 
hereunder and shall be payable by Tenant upon demand by Landlord.

    SECTION 22. RESPONSIBILITY OF TENANT. Tenant shall be responsible for, 
and shall relieve and hereby relieves Landlord from and agrees to indemnify 
Landlord against, any and all liability by reason of any injury or damage to 
Tenant or to any other person or property upon the Premises (or in the said 
common areas in connection with Tenant's use and enjoyment thereof), caused 
by any fire, breakage, leakage, collapse or other event upon the Premises or 
any other portion of the Center, whether or not such event results from a 
condition which existed prior to the execution of this Lease and whether or 
not such event results in the termination of this Lease by reason of damage 
to or destruction of the Center or the Premises, unless such fire, breakage, 
leakage, collapse or other event, injury or damage was caused by or results 
from the negligent or intentionally tortious act or omission of Landlord or 
its agents, officers, invitees, visitors or guests.

    SECTION 23. SUBORDINATION AND ATTORNMENT. This Lease shall be subject and 
subordinate at all times to the lien of any underlying ground leases, 
mortgages or deeds of trust now or hereafter placed by Landlord upon the 
Center, and to any and all advances to be made thereunder, and to all 
renewals, replacements and extensions thereof. This subordination shall be 
self-operative, and no further

                                      -14-


agreement or act on the part of Tenant shall be required to effectuate such 
subordination. In confirmation thereof, Tenant shall execute such further 
assurances as may be requested. Any mortgagee or trustee under any deed 
of trust may elect that this Lease shall have priority over its mortgage or 
deed of trust, and upon notification of such election by such mortgages or 
trustee to Tenant, this Lease shall be deemed to have priority over such 
mortgage or deed of trust whether this Lease is dated prior to or subsequent 
to the date of such mortgage or deed of trust. If any proceedings are brought 
for the foreclosure of any portion of the Center of which the Premises are a 
part, or if the power of sale under a mortgage or deed of trust is exercised, 
then Tenant, upon request, shall attorn to the purchaser upon any such 
foreclosure or sale and recognize such purchaser as the Landlord under this 
Lease. Tenant hereby appoints Landlord to be the attorney-in-fact of Tenant 
(which appointment is irrevocable and coupled with an interest) to execute 
and deliver any such instrument or instruments for and on behalf of and in 
the name of Tenant.

    SECTION 24. DEFAULTS BY THE TENANT.

    24.1. DEFAULT. If any one or more of the following events shall occur: 
(a) Tenant shall fail to make any payment hereunder when due, whether for 
Rent or otherwise; or (b) any financial report or statement, certificate, 
statement, representation or warranty at any time furnished or made by or on 
behalf of Tenant or any guarantor of any of Tenant's obligations hereunder, 
including, without limitation, any representation or warranty made by Tenant 
herein, proves to have been false or misleading in any material respect at 
the time as of which the facts therein set forth were stated or certified, or 
any such financial report or statement has omitted any material contingent or 
unliquidated liability or claim against Tenant or any such guarantor; or (c) 
Tenant or any guarantor of any of Tenant's obligations hereunder shall fail 
to perform or observe any covenant, condition or agreement to be performed or 
observed by it hereunder or under any guaranty agreement; or (d) Tenant or 
any guarantor of Tenant's obligations hereunder shall be in breach of or in 
default in the payment and performance of any obligation owing to Landlord, 
whether or not related to this Lease and howsoever arising, whether by 
operation or law or otherwise, present or future, contracted for or acquired, 
and whether joint, several, absolute, contingent, secured, unsecured, matured 
or unmatured; or (e) Tenant or any guarantor of any of Tenant's obligations 
hereunder shall cease doing business as a going concern, make an assignment 
for the benefit of creditors, generally not pay its debts as they become due 
or admit in writing its inability to pay its debts as they become due, file a 
petition commencing a voluntary case under any chapter of the Bankruptcy 
Code, 11 U.S.C. Section 101, ET SEQ. (the "Bankruptcy Code"), be adjudicated 
an insolvent, file a petition seeking for itself any reorganization, 
arrangement, composition, readjustment, liquidation, dissolution or similar 
arrangement under any present or future statute, law, rule or regulation, or 
file an answer

                                      -15-


admitting the material allegations of a petition filed against it in any such 
proceeding, consent to the filing of such a petition or acquiesce in the 
appointment of a trustee, receiver, custodian or other similar official for 
it or of all or any substantial part of its assets or properties, or take any 
action looking to its dissolution or liquidation; or (f) an order for relief 
against Tenant or any guarantor of any of Tenant's obligations hereunder 
shall have been entered under any chapter of the Bankruptcy Code, or a decree 
or order, by a court having jurisdiction in the premises shall have been 
entered approving as properly filed a petition seeking reorganization, 
arrangement, readjustment, liquidation, dissolution or similar relief against 
Tenant or any guarantor of any of Tenant's obligations hereunder under any 
present or future statute, law, rule or regulation, or within thirty (30) 
days after the appointment without Tenant's or such grantor's consent or 
acquiescence of any trustee, receiver, custodian or other similar official 
for it or such grantor or of all or any substantial part of its or such 
guarantor's assets and properties, such appointment shall not be vacated; 
then Landlord may re-enter and repossess the Premises, together with any and 
all improvements thereon and additions thereto, and/or pursue any remedy 
permitted by law or equity for the enforcement of the provisions hereof. In 
the alternative, and at Landlord's election, Landlord may give to Tenant at 
any time after the occurrence of such default written notice of Landlord's 
election to terminate this Lease on a date to be specified in the notice, not 
less than ten (10) days after the giving thereof; and upon the date specified 
in the notice, this Lease and the Term shall (except for the continued 
liability of Tenant as hereinafter provided) expire and come to an end as 
fully and completely as if the date specified in the notice were the date 
definitely fixed in this Lease for the expiration of the Term, and Tenant 
shall quit and surrender the Premises, on or before the stated date, to the 
Landlord, without cost or charge to Landlord.

    24.2. LANDLORD'S ADDITIONAL REMEDIES FOR DEFAULT. If this Lease or the 
Tenant's possession of the Premises should be terminated as herein provided 
or by reentry, summary dispossession proceedings or any other method then 
Landlord may, at Landlord's option, as an additional or alternative remedy 
(a) relet the Premises or any part or parts thereof for the account of Tenant 
for the remainder of the Term, as herein originally specified, or (b) relet 
the Premises or any part or parts thereof for a period extending beyond the 
date when this Lease would have expired but for such prior expiration on 
default or for such reentry and termination, and deem that portion of the 
period within the Term, as herein originally specified, as a rental for the 
account of Tenant (which such reletting may provide for reasonable 
concessions in rent or a reasonable free rent period, but without thereby in 
any way affecting Tenant's liability hereunder for the Rent payable under 
this Lease for the period of such concession or free rent) and, in any of 
such events, Landlord may receive the rent therefor, applying the same first 
to the payment of such expenses of every kind and nature as the Landlord may 
have incurred or assumed in recovering the possession of the Premises and in 
connection with the reletting of the Premises, and then (to the extent of the 
remainder of so much

                                      -16-





of the said rental as shall have been received with respect to the Term, as 
herein originally specified) to the fulfillment of the covenants and 
agreements of Tenant hereunder including the payment of the Rent herein 
reserved, and Tenant shall remain liable as herein provided, but there shall 
be no obligation on the part of Landlord to relet nor any liability on its 
part for failure to relet, and Tenant's liability shall not be diminished or 
affected by such failure to relet, or the giving of such rental or other 
concessions in the event of any reletting, as aforesaid.

    24.3 TENANT'S LIABILITY FOR DEFAULT. If this Lease is terminated as 
herein provided, or if Tenant's possession is terminated by reentry, summary 
dispossession proceedings or any other method, whether or not the Premises is 
relet, then Tenant shall, until the time when this Lease would have expired 
but for such prior expiration or for such reentry, summary dispossession or 
termination, continue or remain liable for the Rent herein reserved less the 
avails of any such reletting (after the deduction therefrom of all expenses 
incurred by Landlord in recovering such possession and in reletting 
including, but not by way of limitation, broker's fees, reasonable counsel 
fees and costs of renovation), if any, and the same shall be due and payable 
by Tenant to Landlord at the time specified for the payment thereof, so that 
upon each of such days Tenant shall pay to Landlord the amount of the 
deficiency then existing. Upon such expiration, termination or reentry as 
aforesaid, neither Tenant nor Tenant's creditors and representatives shall 
thereafter have any right, legal or equitable, in or to the Center, the 
Premises or any portion thereof, or in or to the repossession of same, or in, 
to or under this Lease, and Tenant hereby waives any and all right or 
redemption which may then be provided by law. The words "reenter" and 
"reentry" as used in this Lease shall not be deemed to be restricted to their 
technical legal meaning.

    24.4 ALL SUMS DEEMED RENT. Any and all mention in this Section 24 of the 
"Rent" herein reserved after the termination of this Lease as in this Section 
24 provided, or after the termination of Tenant's possession by reentry, 
summary dispossession or other method as herein provided, shall be deemed to 
refer to the Basic Rent plus all Additional Rent and such additional sums as 
the Tenant shall be obligated to pay to Landlord under any of the terms, 
covenants and conditions of this Lease, whether or not designated or 
indicated herein to be payable as Basic Rent or Additional Rent, and all such 
sums shall constitute Rent for the purposes of Section 502(b)(6) of the 
Bankruptcy Code, 11 U.S.C. Section 502(b)(6).

    24.5 DISTRAINT FOR RENT. In addition to, and not in substitution for the 
remedies provided in this Section 24, if Tenant fails to pay any rent when 
due, beyond any applicable grace period, Landlord shall have the right to 
distrain therefor.

                                   -17-


    24.6 NO IMPLIED WAIVER OF LANDLORD'S RIGHT. The failure of Landlord to 
insist in any one or more instances upon the performance of any of the 
covenant or conditions of this Lease, or to exercise any right or privilege 
herein conferred shall not be construed as thereafter waiving or relinquishing 
Landlord's right to the performance of any such covenants, conditions, rights 
or privileges, and the same shall continue and remain in full force and 
effect, and the waiver of one default or right shall not constitute waiver of 
any other default, and the receipt of any rent by Landlord from Tenant or any 
assignee or subtenant of Tenant, whether the same be Rent that originally was 
reserved or that which may become payable under any covenants herein 
contained, or of any portion thereof, shall not operate as a waiver of 
Landlord's right to enforce the payment of the Additional Rent or of any of 
the other obligations of this Lease by such remedies as may be appropriate, 
and shall not waive or avoid Landlord's right at any time thereafter to elect 
to terminate this Lease, on account of such assignment, sub-letting, 
transferring of this Lease or any other breach of any covenant or condition 
herein contained, unless evidenced by Landlord's written waiver thereof. The 
acceptance of Rent or any other consideration by Landlord at any time shall 
not be deemed an accord and satisfaction, and Landlord shall have absolute 
discretion to apply same against any sum for any period or reason due 
hereunder without the same constituting a release of any other sums remaining 
due and unpaid.

    24.7 LANDLORD'S COSTS AND EXPENSES. If suit is brought for the recovery 
of possession of the Premises, for the recovery of Rent or any other amount 
due under the provisions of this Lease, for the preservation or enforcement 
of any other rights or remedies accruing to Landlord under this Lease or 
because of the breach of any covenant herein contained on the part of the 
Tenant to be kept or performed, then Tenant shall pay all of Landlord's 
expenses, including reasonable attorneys' fees, and such fees and expenses 
shall be deemed Additional Rent.

    24.8 TENANT'S WAIVER. Tenant shall and hereby does waive trial by jury in 
any action, proceeding or counterclaim brought by Landlord on any matters 
whatsoever arising out of or in any way connected with this Lease, the 
relationship of Landlord and Tenant, Tenant's use or occupancy of the Leased 
Premises and/or any claim of injury or damage. If Landlord commences any 
proceedings for the non-payment of Rent or Tenant will not interpose any 
counterclaim of whatever nature or description in any such proceeding. This 
shall not, however, be construed as a waiver of Tenant's right to assert such 
claims in any separate action or actions brought by Tenant.

    25. GRACE PERIOD. Anything contained in any of the foregoing provisions 
of this Lease to the contrary notwithstanding, neither party hereto will 
exercise any right or remedy provided for in this Lease or allowed by law 
because of any default of the other, unless such party shall first have given 

                                   -18-


notice thereof to the other, and the other, within a period of five (5) days 
thereafter, shall have failed to pay the sum or sums due if the default shall 
consist of the failure to pay money, or, if the default shall consist of 
something other than the payment of money, shall have failed promptly 
thereafter to begin to cure such default, and shall have failed to cure such 
default within a reasonable period of time in any event not to exceed thirty 
(30) days from the date of such notice; provided, that no such notice from 
Landlord shall be required, nor shall the Landlord be required to allow any 
part of the said notice period, (a) more than two (2) times during any twelve 
(12) month period, or (b) if the Tenant shall have removed from or shall be 
in the course of removing from the Premises, or (c) if a petition in 
bankruptcy or for reorganization shall have been filed by or against the 
Tenant, resulting in the entry of an Order For Relief under the Bankruptcy 
Code, 11 U.S.C. Section 101, ET SEQ., or (d) if a receiver or trustee shall 
have been appointed for Tenant and such appointment and such receivership or 
trusteeship shall not be terminated within thirty (30) days thereafter; or 
(e) if the Tenant shall have made an assignment for the benefit of creditors, 
or (f) if Tenant shall have been levied upon and is about to be sold out upon 
the Premises by any sheriff, marshall or constable.

    SECTION 26. NOTICES. All notices required or permitted to be given 
hereunder shall be in writing and shall be sent by registered or certified 
mail, return receipt requested, postage prepaid and shall be deemed given on 
the day on which same were posted. Notices to Tenant shall be addressed to 
Tenant's Notice Address. Notices to Landlord shall be addressed c/o 
Nottingham Properties, Inc., 100 West Pennsylvania Avenue, Towson, Maryland 
21204, with a carbon copy to any other persons designated by Landlord. Either 
party may, at any time, in the manner set forth for giving notices to the 
other, set forth a different address to which notices to it shall be sent.

    SECTION 27. TENANT'S CERTIFICATE. Tenant agrees at any time and from time 
to time within ten (10) days after Landlord's written request, to execute, 
acknowledge and deliver to Landlord a written instrument in recordable form 
certifying or stating: (a) that this Lease is unmodified and in full force 
and effect (or if there shall then have been modifications, that the same is 
in full force and effect as so modified, and setting forth such 
modifications); (b) that the Premises have been completed by Landlord in 
accordance with Section 4 hereof, (or if not so completed, stating the 
respects in which not completed); (c) that Tenant has accepted possession of 
the Premises, the date upon which the Term has commenced and the date of the 
expiration of the Term of this Lease; (d) the dates to which Rent and other 
charges have been paid in advance, if any; (e) whether or not to the best 
knowledge of the signer of such certificate Landlord is then in default in 
the performance of any covenant, agreement or condition contained in this 
Lease and, if so, specifying in detail each such default of which the signer 
may have knowledge; (f) as to any other matters as may be reasonably so 
requested; and (g) that it is understood that such instrument 

                                   -19-


may be relied upon by any prospective purchaser, mortgages, assignee or 
lessee of Landlord's interest in this Lease, in the Center, or any portion or 
part thereof.

    SECTION 28. THE LANDLORD. As used herein, the term "Landlord" means the 
Landlord named hereinabove as well as its heirs, personal representatives, 
successors and assigns, and any other subsequent owner of the leasehold 
estate or reversion in the Premises, as well as the heirs, personal 
representatives, successors and assigns of any such subsequent owner, each of 
whom shall have the same rights, remedies, powers, authorities and privileges 
as he would have had had he originally signed this Lease as Landlord, but any 
such person, whether or not named herein, shall have no liability hereunder 
after he shall cease to hold the title to or a leasehold interest in the said 
real estate, except for obligations which may have theretofore accrued. 
Neither Landlord nor any principal of Landlord, whether disclosed or 
undisclosed, shall have any personal liability with respect to this Lease or 
the Premises, and if Landlord shall breach or default with respect to its 
obligations or otherwise under this Lease, Tenant shall look solely to the 
Premises and to the rents, profits and issues to be received therefrom.

    SECTION 29. THE TENANT. As used herein, the term "Tenant" means the 
Tenant named in this Lease as well as its heirs, personal representatives, 
successors and assigns, each of which shall be under the same obligations, 
liabilities, and disabilities and have only such rights, privileges and 
powers as it would have possessed had it originally signed this Lease as 
Tenant. However, no such rights, privileges or powers shall inure to the 
benefit of any assignee of Tenant, immediate or removed, unless the 
assignment to such assignee shall have been consented to in writing by the 
Landlord, as aforesaid. Any person or entity to which this Lease is assigned 
pursuant to the provisions of the Bankruptcy Code, 11 U.S.C. Section 101, ET 
SEQ., shall be deemed without further act or deed to have assumed all of the 
obligations arising under this Lease on and after the date of such 
assignment. Any such Assignee shall upon demand execute and deliver unto 
Landlord an instrument confirming such assumption.

    SECTION 30. TENANT'S STATEMENT. Tenant shall furnish Landlord, when 
requested, annually, a copy of its annual audited and certified financial 
statement. It is mutually agreed that the Landlord may deliver a copy of such 
statements to its mortgagee and that Landlord's employees may review such 
statements, but otherwise, Landlord shall treat such statements and 
information contained therein as confidential.

    SECTION 31. RECORDING. Neither this Lease, nor any memorandum, affidavit, 
or other writing with respect thereto, shall be recorded by Tenant or by 
anyone acting through, under or on behalf of Tenant, and the recording 
thereof in violation of this provision, shall make this Lease null and void 
at 

                                   -20-




Landlord's election. Notwithstanding the foregoing prohibition, either party 
may request that the other party execute a memorandum or short form lease 
for recording, containing the name of the parties, the legal description and 
term of the Lease. The party so requesting such recordation shall pay all of 
the costs (including any transfer taxes and Recordation taxes) payable in 
connection with such recordation, except that Tenant covenants that if at 
any time any mortgagee of Landlord's interest in the Premises, any trustee or 
beneficiary under a deed of trust constituting a lien upon the Building of 
which deed of trust Landlord is grantor, or a landlord of Landlord in respect 
to the real property upon which the Building is situate, shall require the 
recordation of this Lease, or if the recordation of this Lease shall be 
required by any valid governmental order or if any governmental authority 
having jurisdiction in the matter shall assess and be entitled to collect 
transfer taxes or recordation taxes, or both such taxes on this Lease, then 
Tenant shall execute such acknowledgements as may be necessary to effect such 
recordations and pay, upon request of Landlord, all recording fees, transfer 
taxes and/or recordation taxes payable on, and/or in connection with this 
Lease and/or such recordation.

   SECTION 39. EXCUSE OF LANDLORD'S PERFORMANCE. Anything in this Agreement 
to the contrary notwithstanding, provided such is not due to Landlord's 
willful act or neglect, Landlord shall not be deemed in default with respect

                     LIMITED PARTNERSHIP AS LANDLORD AND
                    TOWSON COPY PRODUCTS, INC., AS TENANT

    Section 46. RENT ABATEMENT. The Tenant shall pay no Basic Rent for the 
first four (4) calendar months of the first Lease Year.

    Section 47. RENEWAL OPTION. Provided Tenant is not in default of any of 
its obligations hereunder and is in possession of the Premises, Tenant shall 
be entitled to renew this Lease for five (5) years immediately following the 
expiration of the original or previous Term on the same terms, conditions, 
and provisions as are set forth in this Lease with the same force and effect 
as though this Lease had originally provided for a nine (9) year, four (4) 
month, Term, with the following conditions:

      (a) Tenant will give written notification to the Landlord no later than 
ninety (90) days prior to the termination date of the original Term of his 
election to renew this Lease.

      (b) Beginning with and as of the first day of the renewal Term, the 
Basic Rent and each monthly installment thereof payable during the renewal 
Term shall be adjusted and modified according to the following formula:

      If the Consumer Price Index for all Urban Consumers (the "Index") for 
Baltimore, Maryland (1967 - 100), as determined and published by the United 
States Department of Labor, Bureau of Labor Statistics, based on all items, 
for the month preceding the commencement of the renewal term shall exceed 
said Index in effect as of the original Term of the Lease, then, in lieu of 
the Basic Rent as set forth in Section 1.6 respecting the original Term of 
the Lease, the Basic Rent for each year of the renewal Term shall be an 
amount equal to the Basic Rent as set forth in Section 1.6 multiplied by a 
fraction, the numerator of which shall be the Index for the month preceding 
the commencement of the renewal Term and denominator of which shall be the 
Index in effect as of the commencement of the original Term of the Lease, 
provided, however, that in no event shall the Basic Rent be less than that 
set forth in Subsection 1.6. The index will be adjusted in the event that 
said Index shall be converted and, if the Index shall cease to be published, 
an Index as nearly comparable as possible shall be used by the parties.

    In witness whereof the parties have hereto set their hands and seals as of 
the day and year first above written.
