                               OFFICE LEASE AGREEMENT

     THIS OFFICE LEASE AGREEMENT ("Lease") is made this ___ day of 
____________, 19__, by and between Riggs Distler & Co., Inc. (the "Landlord") 
and ____________, as formed and existing under the laws of the State of 
Maryland and Imtek Co., Inc. (the "Tenant").

     WITNESSETH, that for good and valuable consideration, the Landlord 
hereby leases to the Tenant, and the Tenant hereby leases from the Landlord, 
certain space containing an agreed-upon amount of 8,300 rentable square feet 
of floor area (the "Premises") on the floor of an office building known as 
2111 Van Deman Street (the "Building"), as more particularly shown on the 
floor plan attached hereto as Exhibit A, which Building together with other 
real property and improvements is located at ____________ in ____________, 
(collectively the "Property"), all upon the following terms and conditions:

                                  ARTICLE I - TERM

     SECTION 1.01  LENGTH.

     This Lease shall be for eighteen (18) months (the "Term") which begins 
on that date (the "Commencement Date") which is the earlier of (i) 
November 15, 1997 (the "Target Date"), (ii) the first date on which the 
initial improvements to the Premises described are substantially complete 
(i.e., sufficient for the Tenant to occupy such Premises and undertake 
business therein), or (iii) the date on which Tenant actually moves into 
occupancy of the Premises and conducts business therein.  The Term shall be 
for one year and six months and shall expire at midnight on the last day of 
the calendar month in which the term shall end May 15, 1999 (the "Expiration 
Date").  In the event that the Tenant enters into occupancy of the Premises 
prior to the Commencement Date for the purpose of constructing improvements 
or installing fixtures therein (and without conducting business therein), 
then all terms of this Lease except that regarding the payment of rent and 
other charges shall apply to such occupancy.

     SECTION 1.02  CONFIRMATION.

     Landlord shall, within 30 days after the commencement of the Term, confirm
to Tenant in writing the actual dates of the Commencement Date and the
Expiration Date.

     SECTION 1.03  SURRENDER.

     The Tenant shall at the expiration of the Term or any earlier 
termination of this Lease (a) promptly surrender to the Landlord possession 
of the Premises, including any fixtures or other improvements which under the 
provisions of this Lease are property of the Landlord, all in good order and 
repair (ordinary wear and tear excepted) and broom clean, (b) remove 
therefrom the Tenant's signs, goods and effects and any machinery, trade 
fixtures and equipment used in conducting the Tenant's trade or business and 
not owned by the Landlord, and (c) repair any damage to the Premises or the 
Building caused by such removal.

     SECTION 1.04  HOLDING OVER.

     If the Tenant continues to occupy the Premises beyond the Expiration Date
or any earlier termination of this Lease, such occupancy shall be subject to all
of the same terms and conditions as are contained in this Lease, except that the
rental payable during the period of such occupancy shall be equal to two times
the amount of all Rent which was last in effect during the Term.  Nothing in the
foregoing shall be deemed in any way to limit or impair the Landlord's right to
immediately evict the Tenant or exercise its other rights and remedies under the
provisions of this Lease or applicable law, including collection of
consequential damages, on account of the Tenant's occupancy of the Premises
without having obtained Landlord's prior consent.

                                 ARTICLE II - RENT

     SECTION 2.01  BASE RENT.

     Tenant shall pay a minimum annual rental in each one-year period during the
Term hereof which shall be referred to hereinafter as "Base Rent." Base Rent
shall be calculated and increased for each such year as follows:

          (1) Base Rent for the first one-year period in the Lease Term shall be
the sum of $99,600.00 payable in equal monthly installments of $8,300.00 each.

          (2) Base Rent for the second sixth (6) month period in the Lease Term
shall be the sum of $51,294.00, payable in equal monthly installments of
$8,549.00 each.

     SECTION 2.02  REAL ESTATE TAXES.







                                    -2-


     SECTION 2.04   WHEN DUE AND PAYABLE.

     (A)   All rental obligations set forth in the foregoing provisions and 
elsewhere in this Lease, except for Base Rent, shall be referred to 
hereinafter as "Additional Rent." All Base Rent and Additional Rent are 
sometimes hereinafter together referred to as "Rent."

     (B)   The Base Rent for each year (or part thereof) during the Term 
shall be due and payable in 12 consecutive, equal monthly installments, in 
advance, on the first day of each calendar month during the Term, provided 
that the installment of Rent for the first full calendar month of the Term 
shall be due upon execution of this Lease. All payments shall be sent to the 
notice address shown in this Lease, or to such other address as Landlord may 
designate in writing.

     (C)   Tenant shall pay all Additional Rent within 30 days after being 
billed therefor by Landlord. However, Landlord may, at its discretion, (a) 
make from time to time during the Term a reasonable estimate of the 
Additional Rent which may become due for any year, (b) require the Tenant to 
pay to the Landlord such Additional Rent in equal installments at the time 
and in the manner that the Tenant is required hereunder to pay monthly 
installments of Base Rent, and (c) at the Landlord's reasonable discretion, 
increase or decrease from time to time during such year the amount initially 
estimated for such year, all by giving the Tenant written notice thereof. In 
such event, the Landlord shall cause the actual amount of such Additional 
Rent to be calculated, and the Tenant or the Landlord shall within 30 days 
pay to the other the amount of any deficiency or overpayment, whichever the 
case may be.

     (D)   Landlord shall have the right to apply any payment of Rent by 
Tenant to any amounts outstanding, in any order, in Landlord's sole 
discretion. Acceptance by Landlord of any partial payment of Rent shall not 
be deemed a waiver or satisfaction of the Tenant's obligation to pay all 
remaining amounts of Rent hereunder, which amounts shall remain due in their 
entirety according to the terms of this Lease.

     SECTION 2.05   PRORATION.

     All items of Rent shall be prorated, based on actual days elapsed, for 
any month during the Term which is not a full calendar month or in which two 
different rental rates are applicable. Appropriate prorations shall also be 
made in determining the Tenant's proportionate share of increases in Real 
Estate Taxes to the extent the tax/fiscal year is not a calendar year. In 
addition, at Landlord's election, the Tenant's proportionate share of 
increases in Real Estate Taxes and in Operating Expenses may be calculated on 
a per square foot basis; in this case, the Tenant's proportionate share shall 
be equal to (a) the difference between (1) the total Real Estate Taxes or 
Operating Expenses (as the case may be) for the year in question divided by 
the square footage of the Building and (2) the Base Real Estate Taxes or Base 
Operating Expenses (as the case may be) divided by the square footage of the 
Building, (b) multiplied by the number of rentable square feet in the 
Premises. If only part of any calendar year falls within the Term, the amount 
computed as Additional Rent for such calendar year under the foregoing 
provisions of this section shall be appropriately prorated, but the 
expiration of the Term before the end of a calendar year shall not limit the 
Tenant's obligation hereunder to pay the prorated portion of Additional Rent 
applicable to that portion of such calendar year falling within the Term.

                                      -3-



     SECTION 2.06   LATE PENALTIES.

     Each such payment of Rent shall be made promptly when due, without any 
demand, deduction or setoff whatsoever, at the place directed by Landlord. 
Any payment of Rent not made when due shall, at Landlord's sole option, bear 
interest at the rate of 18% per annum from the due date until paid. 
Additionally, any payment of Rent not paid within 10 days of when due shall 
be considered delinquent and subject to a late payment charge, for each 
occurrence of delinquency, of 5% of the amount overdue and payable. This late 
payment charge shall be in addition to the interest provided for above and 
shall be due and payable with the next succeeding Rent payment. The 
obligation to pay Rent shall survive termination of this Lease.

     SECTION 2.07   SECURITY DEPOSIT.

     Upon signing this Lease, Tenant shall deposit with the Landlord the sum 
of $8,300.00, which shall be retained by the Landlord as security for the 
Tenant's payment of Rent and performance of all of its other obligations 
under the provisions of this Lease. On the occurrence of an Event of Default 
(as defined herein), the Landlord shall be entitled, at its sole discretion, 
to (i) apply any or all of such sum in payment of any Rent then due and 
unpaid, any expense incurred by the Landlord in curing any such default, 
and/or any damages incurred by the Landlord by reason of such default 
(including but not limited to attorneys' fees), in which event Tenant shall 
immediately restore the amount so applied, and/or (ii) to retain any or all 
of such sum in liquidation of any or all damages suffered by the Landlord by 
reason of such default. However, the foregoing shall not serve in any event 
to limit the rights, remedies and damages accruing to Landlord under Article 
XIV or any other provision of this Lease on account of default by Tenant. The 
security deposit shall not be applied to the last month's installment of 
Rent; rather, upon the termination of this Lease, any of such security 
deposit then remaining shall be returned to the Tenant. Such security deposit 
shall not bear interest while being held by the Landlord hereunder.

                           ARTICLE III - USE OF PREMISES

     SECTION 3.01   USE.

     The Tenant shall use the Premises as a business office and for no other 
purposes.

     SECTION 3.02   LAWS.

     Tenant shall comply with any and all federal, state and local laws, 
ordinances and regulations, including but not limited to the Americans With 
Disabilities Act, applicable to the Premises, to the Tenant's use of the 
Premises or to any common areas of the Property, and Tenant shall make any 
changes or improvements to the Premises required thereby, subject to Section 
5.03 hereof.

     SECTION 3.03   COMMON AREAS.

     The Landlord hereby grants to the Tenant a non-exclusive license to use 
(a) all elevators, stairways, lobbies, hallways and other common areas of the 
Building, and (b) all portions of the grounds on which the Building is 
located which are manifestly designed and intended for common use by the 
occupants of the Building, all for pedestrian ingress and egress to and from 
the Premises. Such license shall be exercised in common with the Landlord and 
other tenants and their respective employees and invitees and in accordance 
with the Rules and Regulations promulgated from time to time pursuant to the 
provisions of Article XI.

     SECTION 3.04   RELOCATION.

     The Landlord shall have the right from time to time during the Term, at 
the Landlord's expense, to relocate the Tenant's Premises from its present 
location within the Building to another location within the Building having 
at least the same floor area, provided that the Landlord gives the Tenant 
written notice of the Landlord's intention to do so at least 60 days before 
undertaking such relocation. In such event, the Landlord shall, at the 
Landlord's expense, install within the Premises as so relocated improvements 
of the same quality and quantity as those made by the Tenant or the Landlord 
to the Premises, and on the completion of such installation shall cause the 
Tenant's machinery, furniture, fixtures and equipment within the Premises to 
be moved to the Premises as so relocated. Upon the completion of such 
relocation, this Lease shall automatically cease to cover the space 
constituting the Premises immediately before such relocation, and shall 
automatically thereafter cover the space to which the Premises have been 
relocated, as aforesaid, all on the same terms and subject to the same 
conditions as those set forth in the provisions of this

                                      -4-



Lease as in effect immediately before such relocation, and all without the 
necessity of further action by either party hereto. Also, the Base Rent shall 
be adjusted on the basis of the per square foot rates otherwise in effect, 
and the Tenant's Proportionate Share of Real Estate Taxes and Operating 
Expenses shall be proportionately adjusted, to reflect any difference between 
the size of the Premises prior to relocation and that after relocation. Each 
party hereto shall, promptly upon its receipt of a written request therefor 
from the other, enter into such amendment of this Lease as the requesting 
party considers reasonably necessary to confirm such relocation.

                   ARTICLE IV - INSURANCE AND INDEMNIFICATION

     SECTION 4.01   TENANT'S INSURANCE.

     The Tenant shall procure and maintain, at its expense and throughout the 
Term, the following insurance:

          (a)   General public liability insurance against loss or liability 
in connection with bodily injury, death, property damage or destruction 
occurring within the Premises or arising out of the use thereof by the Tenant 
or its agents, employees, invitees and licensees, having such limits as are 
reasonably required by the Landlord from time to time, but in any event not 
less than (i) $1,000,000 for bodily injury to or death of any one person 
during any one occurrence, (ii) $2,000,000 for bodily injury to or death of 
all persons in any one occurrence, and (iii) $500,000 for property damage or 
destruction during any one occurrence;

          (b)   Contractual liability insurance covering all contractual 
indemnities by Tenant contained in this Lease;

          (c)   All-risk casualty insurance covering all alterations and 
improvements to the Premises (regardless of ownership) and all furniture, 
equipment and fixtures of the Tenant in the Premises up to the replacement 
value of such property. Each liability policy shall name the Tenant, the 
Landlord, and the Landlord's managing agent (and, at the Landlord's request, 
any mortgagee) as the insureds thereunder. Each liability, property, and 
other policy shall (i) by its terms, not be cancelable without at least 30 
days' prior written notice to the Landlord (and, at the Landlord's request, 
any mortgagee), and (ii) be issued by an insurer of recognized responsibility 
licensed to issue such policy in the state in which the premises are located 
and having a Best's rating of A- or better. At least 5 days before the 
Commencement Date, Tenant shall deliver to the Landlord a copy or certificate 
of each such policy. At least 30 days before any such policy expires, Tenant 
shall deliver to the Landlord a certificate of renewal or replacement 
therefor.

     SECTION 4.02   LANDLORD'S INSURANCE.

     The Landlord shall maintain throughout the Term all-risk or fire and 
extended coverage insurance upon the Building in an amount of at least 80% of 
the replacement value thereof. The cost of the premiums for such insurance 
and of each endorsement thereto shall be deemed, for purposes of Section 2.03 
hereof, to be a cost of operating and maintaining the Property.

     SECTION 4.03   WAIVER OF SUBROGATION.

     Landlord and Tenant agree that neither shall be liable to the other for 
loss or injury to the extent such loss or injury is required to be insured 
against hereunder. This agreement shall be binding whether or not such loss 
or injury is caused by negligence of either party or their contractors, 
agents, employees, invitees or licensees. Each party further agrees that each 
will cause its policies of insurance to contain a clause providing that the 
insurance shall not be invalidated should the insured waive in writing prior 
to a loss any or all right of recovery against any person or entity for loss 
covered by such insurance.

     SECTION 4.04   INDEMNIFICATION.

     Tenant hereby agrees to indemnify and hold Landlord harmless from and 
against any cost, damage, claim, liability or expense (including attorney's 
fees) incurred by or claimed against Landlord, directly or indirectly, as a 
result of or in any way arising from Tenant's use and occupancy of the 
Premises or in any other manner which relates to the business of Tenant. The 
liability of Tenant to indemnify Landlord shall not extend to any matter 
against which Landlord shall be effectively protected by insurance, provided, 
however, that if any such liability exceeds the amount of effective and 
collectable insurance, said liability of Tenant shall apply to such excess. 
Furthermore, Tenant acknowledges that Landlord is not responsible for any 
theft, damage, or other loss, regardless of the reason or cause, to the 
equipment, appliances, furniture,

                                      -5-



or other personal property of the Tenant or Tenant's employees or customers 
occurring in or about the Premises.

                      ARTICLE V - IMPROVEMENTS TO PREMISES

     SECTION 5.01   INITIAL IMPROVEMENTS.





                                      -6-



     SECTION 5.02   ACCEPTANCE.

     Except for latent defects or work to be performed by Landlord pursuant 
to Section 5.01 above but remaining incomplete, the Tenant shall for all 
purposes of this Lease be deemed to have accepted the Premises as is upon 
assuming occupancy thereof and to have acknowledged the Premises to be in the 
condition required hereunder.

     SECTION 5.03   TENANT'S ALTERATIONS.

     The Tenant shall not make any alteration, addition or improvement to the 
Premises, whether structural or nonstructural and including any signs or 
other items which may be visible from the exterior of the Premises, without 
the Landlord's prior written consent. Tenant shall provide such drawings, 
plans and specifications as are requested by Landlord in reviewing any such 
proposed improvements. If the Landlord consents to any such proposed 
alteration, addition or improvement, it shall be made at the Tenant's sole 
expense (and the Tenant shall hold the Landlord harmless from any cost 
incurred on account thereof), and at such time and in such manner as to not 
unreasonably interfere with the use and enjoyment of the remainder of the

                                      -7-


Property by any other tenant or other person. All such alterations and 
improvements shall comply in all respects with any and all applicable 
federal, state and local laws, ordinances and regulations, including but not 
limited to the Americans With Disabilities Act and regulations promulgated 
thereunder. Furthermore, Tenant shall indemnify Landlord from all damages, 
losses or liability arising from such alterations or improvements or the 
construction thereof by Tenant or by any other party other than Landlord.

     SECTION 5.4 MECHANICS' LIENS.

     The Tenant shall (a) immediately bond or have released any mechanics', 
materialman's or other lien filed or claimed against any or all of the 
Premises, the Building, or any other property owned or leased by the Landlord 
by reason of labor or materials provided for the Tenant or any of its 
contractors or subcontractors, or otherwise arising out of the Tenant's use 
or occupancy of the Premises, and (b) defend, indemnify and hold harmless the 
Landlord against and from any and all liability or expense (including but not 
limited to attorneys' fees) incurred by the Landlord on account of any such 
lien or claim.

     SECTION 5.05 FIXTURES.

     Any and all improvements, repairs, alterations or other property attached 
to, used in connection with or otherwise installed within the Premises by the 
Landlord or the Tenant shall, immediately on the completion of their 
installation, become the Landlord's property without payment therefor by the 
Landlord, except that any furniture, appliances and office equipment 
installed by the Tenant and used in the conduct of the Tenant's trade or 
business (rather than to service the Premises or any of the remainder of the 
Building or the Property) shall remain the Tenant's property.

                       ARTICLE VI - MAINTENANCE AND SERVICES

     SECTION 6.01 ORDINARY SERVICES.

     During the hours of 8:00 a.m. to 6:00 p.m. Monday through Friday and 8:00 
a.m. to 1:00 p.m. on Saturdays (except federal holidays) in the appropriate 
seasons of the year, Landlord shall provide heating and air-conditioning to 
the Premises for the comfortable use and occupancy of the Premises. In 
addition, Landlord shall provide (a) electricity and water suitable for the 
use of the Premises in accordance with the provisions of Section 3.01, (b) 
automatic elevator service within the Building, and (c) janitorial service 
and trash removal service.

     SECTION 6.02 EXTRAORDINARY SERVICES.

     The Landlord shall not be obligated to provide to or for the benefit of 
the Premises any of the services referred to in the provisions of Section 
6.01 above other than during the hours referred to therein. If the Tenant 
requests such services to be continued during extended hours, Tenant shall 
pay to the Landlord as Additional Rent the amount from time to time charged 
by the Landlord for such extended service, such amount to be calculated as a 
function of the costs to provide such services during extended hours and the 
number of tenants sharing same at the time requested.

     SECTION 6.03 EXCESSIVE USE.

     The Tenant shall not, without first obtaining the Landlord's written 
consent thereto, install within the Premises any electrical machinery, 
appliances or equipment (including, by way of example rather than of 
limitation, any electrical heating, cooking, water-heating or refrigeration 
equipment, kitchen equipment, photocopying equipment, electronic data 
processing machinery, reproduction equipment or punch-card machinery) which 
uses electrical current in excess of that which is standard for the Building, 
and Tenant shall pay as Additional Rent the additional expense incurred by 
the Landlord as a result of any of the foregoing, including that resulting 
from any installation of such equipment. In the event Landlord determines 
Tenant is consuming a disproportionate amount of electricity or other 
utilities at the Premises in relation to other tenants, and regardless of 
whether such determination is reached by surveys, submetering, or other 
methods, Landlord may, at its option, either (a) install at Tenant's expense 
a submeter gauging consumption of the respective utility at the Premises, in 
which case Tenant shall arrange to pay such utility directly to the supplier, 
or (b) require that Tenant pay Landlord monthly, as Additional

                                      -8-


Rent, the cost of such additional electricity or other utilities, which cost 
shall be estimated on a monthly basis by the Landlord using its reasonable 
discretion.

     SECTION 6.04 MAINTENANCE BY TENANT.

     The Tenant shall at all times maintain the interior of the Premises in 
good, clean and safe repair and condition, ordinary wear and tear excepted.

     SECTION 6.05 MAINTENANCE BY LANDLORD.

     The Landlord shall furnish, supply and maintain in good order and repair 
(a) the roof and other structural portions of the exterior of the Building, 
(b) all hallways, stairways, lobbies, elevators, heating and air-conditioning 
facilities and restroom facilities, (c) all standard interior light fixtures 
and bulbs, including that within the Premises, and (d) all other common areas.

     SECTION 6.06 INTERRUPTION.

     The Landlord shall have no liability to the Tenant on account of any 
failure, modification or interruption of electricity, water or other utility 
or HVAC or other service, but in the event of interruption Landlord shall 
take reasonable steps to provide for the resumption of such service to the 
extent the same is within Landlord's control.

                        ARTICLE VII - RIGHT OF ENTRY

     SECTION 7.01 RIGHT OF ENTRY.

     Landlord and its agents and contractors shall be entitled to enter the 
Premises at any time (a) to inspect the Premises, (b) to exhibit the Premises 
to any existing or prospective purchaser, tenant or mortgagee thereof, (c) to 
make any alteration, improvement or repair to the Building or the Premises, 
or (d) for any other purpose relating to the operation or maintenance of the 
Property, all provided that the Landlord shall (1) give the Tenant at least 
24 hours' prior notice of its intention to enter the Premises (unless doing 
so is impractical or unreasonable because of emergency), and (2) use 
reasonable efforts to avoid interfering with the Tenant's use and enjoyment 
thereof.

                        ARTICLE VIII - CASUALTIES

     SECTION 8.01 GENERAL.

     If the Premises are damaged by fire or other casualty during the Term, 
then the following shall apply:

     (A) The Landlord shall restore the Premises with reasonable promptness, 
taking into account the time required by the Landlord to effect a settlement 
with, and to procure any insurance proceeds from, any insurer against such 
casualty, to substantially the same condition as existed immediately before 
such casualty. Landlord may temporarily enter and possess any or all of the 
Premises for such purpose. The Landlord shall not be obligated to repair, 
restore or replace any fixture, improvement, alteration, furniture or other 
property owned or installed by the Tenant.

     (B) The times for commencement and completion of any such restoration 
shall be extended for the period of any delay arising due to force majeure 
causes beyond the Landlord's control. If the Landlord undertakes to restore 
the Premises and such restoration is not accomplished within 180 days plus 
the period of any extension for force majeure as aforesaid, the Tenant may 
terminate this lease by giving written notice thereof to the Landlord within 
30 days after the expiration of such period as so extended.

     (C) From the time of such casualty to the completion of restoration as 
described above, Tenant's rental obligations shall be abated proportionately 
from that portion of the Premises which is rendered untenantable as a result 
of the casualty.

     SECTION 8.02 SUBSTANTIAL DESTRUCTION.

     Anything contained in the foregoing provisions of this section to the 
contrary notwithstanding:

     (A) If during the Term the Building is so damaged by fire or other 
casualty that (a) either the Premises or the Building are rendered 
substantially unfit for occupancy, as reasonably determined by the Landlord, 
or (b) the Building is damaged to the extent that the Landlord elects to 
demolish the Building, or if any mortgagee or lender requires that any or all 
of the insurance


                                      -9-



proceeds issued on account thereof be used to retire any or all of the debt 
secured by mortgage, then in any such case the Landlord may elect to 
terminate this Lease as of the date of such casualty by giving written notice 
thereof to the Tenant within 60 days after such date; and

     (B) In such event, (1) the Tenant shall pay to the Landlord the Base Rent 
and any Additional Rent payable by the Tenant hereunder and accrued through 
the date of such casualty, (2) the Landlord shall repay to the Tenant any and 
all prepaid Rent for periods beyond such casualty, and (3) the Landlord may 
enter upon and repossess the Premises without further notice.

     SECTION 8.03 TENANT'S NEGLIGENCE.

     Anything contained in any provision of this Lease to the contrary 
notwithstanding, if any such damage to the Premises, the Building or Property 
are caused by or result from the negligent or intentional act or omission of 
the Tenant or any of its employees, contractors, agents, invitees or 
licensees, then (a) the Rent shall not be abated or apportioned as aforesaid, 
and (b) the Tenant shall pay to the Landlord upon demand, as Additional Rent, 
the cost of (i) any repairs and restoration made or to be made as a result of 
such damage, or (ii) (if the Landlord elects not to restore the Building) any 
damage or loss which the Landlord incurs as a result of such damage, except 
if and to the extent that the Tenant is released from liability therefor 
pursuant to the provisions of Section 4.03 hereof.

                      ARTICLE IX - CONDEMNATION

    SECTION 9.01 RIGHT TO AWARD.

     If any or all of the Premises are taken by the exercise of any power of 
eminent domain or are conveyed to or at the direction of any governmental 
entity under a threat of any such taking (each of which a "Condemnation"), 
the Landlord shall be entitled to collect from the condemning authority 
thereunder the entire amount of any award or consideration for such 
conveyance, without deduction therefrom for any leasehold or other estate 
held by the Tenant under this Lease. The Landlord shall be entitled to 
conduct any condemnation proceeding and any settlement connected therewith 
free of interference from the Tenant, and the Tenant hereby waives any right 
which it has to participate therein. However, the Tenant may seek, in a 
separate proceeding, a separate award on account of any damages or costs 
incurred by the Tenant as a result of any such Condemnation, so long as such 
separate award in no way diminishes any award or payment which the Landlord 
would otherwise receive as a result of such Condemnation.

     SECTION 9.02 EFFECT OF CONDEMNATION.

     If (a) all of the Premises are covered by a Condemnation, or (b) any part 
of the Premises is covered by a Condemnation and the remainder is 
insufficient for the reasonable operation of the Tenant's business, or (c) 
any of the Building is covered by a Condemnation and, in the Landlord's 
reasonable opinion, it would be impractical to restore the remainder thereof, 
or (d) any of the rest of the Property is covered by a Condemnation and, in 
the Landlord's reasonable opinion, it would be impractical to continue to 
operate the remainder of the Property thereafter, then, in any such event, 
the Term shall terminate on the date on which possession of the property 
covered by such Condemnation is taken by the condemning authority thereunder, 
and all Rent (including any Additional Rent and other charges payable 
hereunder) shall be apportioned and paid to such date. If there is a 
Condemnation and the Term does not terminate pursuant to the foregoing 
provisions of this subsection, the operation and effect of this Lease shall 
be unaffected by such Condemnation, except that the Base Rent shall be 
reduced in proportion to the square footage of floor area, if any, of the 
Premises covered by such Condemnation.

     SECTION 9.03 INTERRUPTION.

     If there is a Condemnation, the Landlord shall have no liability to the 
Tenant on account of any (a) interruption of the Tenant's business upon the 
Premises, (b) diminution in the Tenant's ability to use the Premises, or (c) 
other injury or damage sustained by the Tenant as a result of such 
Condemnation.

                   ARTICLE X - ASSIGNMENT AND SUBLETTING

     SECTION 10.01 CONSENT.

     Tenant agrees to not (a) assign any of its rights under this Lease or (b) 
make or permit any sublease, license, mortgage, pledge or other transfer of 
any part of the Premises (any of the


                                      -10-



foregoing in (a) or (b) hereinafter referred to as a "Transfer"), without 
first obtaining the Landlord's written consent thereto, which consent may be 
given or withheld by the Landlord in its sole and absolute subjective 
discretion. If consent to any one Transfer is given, such consent shall not 
extend to any subsequent Transfer. The Landlord shall be entitled, at its 
sole discretion, to condition any such consent upon the entry by such person 
into an agreement with (and in form and substance satisfactory to) the 
Landlord, by which it assumes all of the Tenant's obligations hereunder. Any 
person to whom any Transfer is attempted without such consent shall have no 
claim, right or remedy whatsoever hereunder against the Landlord, and the 
Landlord shall have no duty to recognize any person claiming under or through 
such Transfer. The sale, assignment or other transfer of a controlling 
interest in the ownership of Tenant (if a corporation), the sale, assignment 
or other transfer of any general partnership interest in Tenant (if a 
partnership), the sale of substantially all of Tenant's assets, and the 
merger of Tenant into another organization, after which merger Tenant shall 
not be the surviving corporation or partnership, shall each be considered a 
Transfer for the purposes of this Lease.

     SECTION 10.02 NO RELEASE.

     No such Transfer or other action taken with or without the Landlord's 
consent shall in any way relieve or release the Tenant from full liability 
for the timely performance of all of the Tenant's obligations under this 
Lease.

     SECTION 10.03 EXCESS RENTS.

     In the event that Tenant effects a Transfer and at any time receives 
periodic rent and/or other consideration which exceeds that which Tenant is 
obligated to pay to Landlord hereunder, Tenant shall pay to Landlord all of 
such excess rent or other consideration promptly (but in no event later than 
2 days) after receipt of such monies.

     SECTION 10.04 LANDLORD'S TRANSFERS.

     Landlord shall have the unrestricted right to assign or transfer this 
Lease to purchasers of the Building, to holders of mortgages or deeds of trust 
on the Building, or to any other party.

                     ARTICLE XI - RULES AND REGULATIONS

     SECTION 11.01 LANDLORD'S RULES.

     The Landlord shall have the right to impose and subsequently modify, from 
time to time and at its sole discretion, reasonable rules and regulations 
(hereinafter referred to as the "Rules and Regulations") having uniform 
applicability to all tenants of the Building (subject to the provisions of 
their respective leases) and governing their use and enjoyment of the 
Building and the remainder of the Property. The Tenant and its agents, 
employees, invitees and licensees shall comply with such Rules and 
Regulations. A copy of the Rules and Regulations in effect on the date hereof 
is attached hereto as Exhibit C.

                             ARTICLE XII - MORTGAGE LENDERS

     SECTION 12.01 SUBORDINATION.

     This Lease shall be subject and subordinate to the lien, operation and 
effect of each mortgage, deed of trust, ground lease and/or other similar 
instrument covering any or all of the Premises or the Property, and each 
renewal, modification or extension thereof (each of which referred to as a 
"Mortgage"), all automatically and without the necessity of any further 
action by either party hereto, provided, however, that in the event the 
beneficiary under any such Mortgage (referred to as a "Mortgagee") succeeds to 
the interest of Landlord hereunder through foreclosure or otherwise, such 
Mortgagee shall honor this Lease and not disturb Tenant in its possession of 
the Premises except upon an Event of Default (defined in Section 14.01 
below). In addition, Tenant shall attorn to any such Mortgagee and agrees that 
such Mortgagee shall not be liable to Tenant for any defaults by Landlord 
under this Lease or for any other event occurring prior to such Mortgagee's 
succeeding to the interest of Landlord hereunder.

     SECTION 12.02 WRITTEN AGREEMENT.

     The Tenant shall, within 7 days after request by the Landlord or any 
Mortgagee, execute, acknowledge and deliver such further instrument as is 
requested by Landlord or any Mortgagee to acknowledge the rights of the 
parties described in Section 12.01 above and providing such other

                                      -11-



information and certifications as is reasonably requested. Any Mortgagee may 
at any time subordinate the lien of its Mortgage to the operation and effect 
of this Lease without obtaining the Tenant's consent thereto, in which event 
this Lease shall be deemed to be senior to such Mortgage without regard to 
their respective dates of execution, delivery and/or recordation among the 
land records of the jurisdiction in which the Property is located.

     SECTION 12.03 ESTOPPEL CERTIFICATE.

     The Tenant shall from time to time, within 7 days after request by the 
Landlord or any Mortgagee, execute, acknowledge and deliver to the Landlord 
(or, at the Landlord's request, to any existing or prospective purchaser, 
assignee or Mortgagee) a written certification (a) that this Lease is 
unmodified and in full force and effect (or, if there has been any 
modification, stating the nature of such modification), (b) as to the dates 
to which the Base Rent and any Additional Rent and other charges arising 
hereunder have been paid, (c) as to the amount of any prepaid Rent or any 
credit due to the Tenant hereunder, (d) that the Tenant has accepted 
possession of the Premises and all improvements thereto are as required 
hereunder, and the date on which the Term commenced, (e) as to whether, to 
the best knowledge, information and belief of the Tenant, the Landlord or 
the Tenant is then in default in performing any of its obligations hereunder 
(and, if so, specifying the nature of each such default), and (f) as to any 
other fact or condition reasonably requested by the Landlord or such other 
party. Any such certificate may be relied upon by the Landlord and any such 
other party to whom the certificate is directed.

                  ARTICLE XIII - ENVIRONMENTAL COVENANTS

     SECTION 13.01 PROHIBITIONS.

     Tenant agrees that Tenant, its employees, licensees, invitees, agents and 
contractors shall not use, manufacture, release, store or dispose of on, 
under or about the Premises any explosives, flammable substances, radioactive 
materials, asbestos in any form, paint containing lead, materials containing 
urea formaldehyde, polychlorinated biphenyls, or any other hazardous, toxic or 
dangerous substances, wastes or materials, whether having such 
characteristics in fact or defined as such under federal, state or local laws 
or regulations and any amendments thereto (all such materials and substances 
being hereinafter referred to as "Hazardous Materials") provided that Tenant 
may store products which are of a type customarily found in offices (such as 
toner for copiers and the like) in a safe and lawful manner and without 
contaminating the Premises or the environment.

     SECTION 13.02 INSPECTION.

     Landlord, in addition to its other rights under this Lease, may enter 
upon the Premises at any time for the purposes of inspecting to determine 
whether the Premises or the environment have become contaminated with 
Hazardous Materials. In the event Landlord discovers the existence of any 
such Hazardous Materials due to fault or other act of Tenant or its agents, 
employees, invitees or licensees, Tenant shall reimburse Landlord upon demand 
for the costs of such inspection, sampling and analysis.

     SECTION 13.03 INDEMNIFICATION.

     Without limiting the above, Tenant shall indemnify and hold harmless 
Landlord from and against any and all claims, losses, liabilities, damages, 
costs and expenses, including without limitation attorneys' fees and the 
costs of any required or necessary repair, cleanup or detoxification, arising 
out of or in any way connected with the existence, use, manufacture, storage 
or disposal of Hazardous Materials by Tenant or its employees, agents, 
invitees, licensees or contractors on, under or about the Premises, the 
Building or the Property. The indemnity obligations of Tenant under this 
clause shall survive any termination of this Lease.

                   ARTICLE XIV - DEFAULTS AND REMEDIES

     SECTION 14.01 DEFAULTS.

     As used in the provisions of this Lease, each of the following events 
shall constitute, and is hereinafter referred to as, an "Event of Default".

     (A) If the Tenant fails to (1) pay any Rent or any other sum which it is 
obligated to pay by any provision of this Lease, when and as due and payable 
hereunder, or (2) perform any of its other obligations under the provisions 
of this Lease; or
                                      -12-


    (B)  If the Tenant or any guarantor of this Lease (1) applies for or 
consents to the appointment of a receiver, trustee or liquidator of the Tenant 
or of all or a substantial part of its assets, (2) is subject to a petition 
in bankruptcy or admits in writing its inability to pay its debts as they 
come due, (3) makes an assignment for the benefit of its creditors, (4) files 
a petition or an answer seeking a reorganization or an arrangement with 
creditors, or seeks to take advantage of any insolvency law, (5) performs any 
other act of bankruptcy, or (6) files an answer admitting the material 
allegations of a petition filed against the Tenant in any bankruptcy, 
reorganization or insolvency proceeding; or

    (C)  If the Tenant fails to assume possession and occupancy of the 
Premises within 15 days after the Commencement Date, or if thereafter the 
Tenant vacates or abandons the Premises for more than 3 continuous days.

    SECTION 14.02 GRACE PERIOD.

    Anything contained in the provisions of this article to the contrary 
notwithstanding, on the occurrence of an Event of Default, the Landlord shall 
not exercise any right or remedy which it holds under any provision of this 
Lease or applicable law unless and until:

    (A)  The Landlord has given written notice thereof to the Tenant, and 

    (B)  The Tenant has failed, (1) if such Event of Default consists of a 
failure to pay money, to pay all such money within 5 days after such notice, 
or (2) if such Event of Default consists of something other than a failure to 
pay money, to fully cure such Event of Default within 15 days after such 
notice or, if such Event of Default cannot be cured within 15 days and Tenant 
commences to cure same within 15 days, to fully cure such Event of Default 
within 30 days; all provided, that

    (C)  No such notice shall be required, and the Tenant shall be entitled 
to no such grace period, (1) in any emergency situation in which the Landlord 
acts to cure such Event of Default pursuant to the provisions of Paragraph 
(B) in Section 14.03 below, or (2) an Event of Default occurs more than twice 
during any 12 month period, or (3) if the Tenant has substantially terminated 
or is in the process of substantially terminating its continuous occupancy 
and use of the Premises, or (4) in the case of any Event of Default 
enumerated in the provisions of Paragraph (B) in Section 14.01 above.

    SECTION 14.03 REMEDIES.
    
    Upon the occurrence of any Event of Default, the Landlord may (subject to 
Section 14.02 above) take any or all of the following actions:

    (A)  Sell at public or private sale all or any part of the fixtures, 
equipment, inventory and other property belonging to Tenant and in which the 
Tenant has granted a lien to Landlord under Section 14.05 below, at which 
sale Landlord shall have the right to become the purchaser upon being the 
highest bidder, and apply the proceeds of such sale, first, to the payment of 
all costs and expenses of seizing and storing such property and conducting 
the sale (including all attorneys' fees), second, toward the payment of any 
indebtedness, including (without limitation) that for Rent, which may be or 
may become due from Tenant to Landlord, and, third, to pay Tenant any surplus 
remaining after all indebtedness of Tenant to Landlord including expenses has 
been fully paid;

    (B)  Perform on behalf of and at the expense of Tenant any obligation of 
Tenant under this Lease which Tenant has failed to perform, without prior 
notice to Tenant, the total cost of which by Landlord, together with interest 
thereon at the rate of 18% per annum from the date of such expenditure, shall 
be deemed Additional Rent and shall be payable by Tenant to Landlord upon 
demand;

    (C)  With or without terminating this Lease and the tenancy created 
hereby, re-enter the Premises with or without court action or summary 
proceedings, remove Tenant and all other persons and property from the 
Premises, and store any such property in a public warehouse or elsewhere at 
the costs of and for the account of Tenant, all without resort to legal 
process and without Landlord being deemed guilty of trespass or liable for 
any loss or damage occasioned thereby;

    (D)  With or without terminating this Lease, and from time to time, make 
such improvements, alterations and repairs as may be necessary in order to 
relet the Premises, and relet the Premises or any part thereof upon such term 
or terms (which may be for a term extending beyond the term of this Lease) at 
such rental or rentals and upon such other terms and conditions (which may 
include concessions, free rent and/or improvements) as Landlord in its sole 
discretion may deem advisable; and, upon each such reletting, all rentals 
received by Landlord shall be applied, first, to the payment of any 
indebtedness other than Rent due hereunder from Tenant to 

                                     -13-


Landlord, second, to the payment of all costs and expenses of such reletting 
(including but not limited to brokerage fees, attorneys' fees and costs of 
improvements, alterations and repairs), third, to the payment of all Rent due 
and unpaid hereunder, and the balance, if any, shall be held by Landlord and 
applied in payment of future rent as the same may become due and payable 
hereunder; and/or 

    (E)  Exercise any other legal or equitable right or remedy which it may 
have by law or otherwise.

         No reentry or taking possession of the Premises by Landlord shall be 
construed as an election on its part to terminate this Lease unless a written 
notice of such intention be given to Tenant or unless the termination thereof 
be decreed by a court of competent jurisdiction. Notwithstanding that 
Landlord may have re-leased the Premises without termination, Landlord may at 
anytime thereafter elect to terminate this Lease for any previous default. If 
the Premises or any part thereof is re-leased, Landlord shall not be liable 
for, nor shall Tenant's obligations hereunder be diminished by reason of, any 
failure by Landlord to relet the Premises or any failure by Landlord to 
collect any rent due upon such reletting. No action taken by the Landlord 
under the provisions of this section shall operate as a waiver of any right 
which the Landlord would otherwise have against the Tenant for the Rent 
hereby reserved or otherwise, and the Tenant shall at all times remain 
responsible to the Landlord for any loss and/or damage suffered by the 
Landlord by reason of any Event of Default.

    SECTION 14.04 DAMAGES.

    Upon any Event of Default, Tenant shall remain liable to the Landlord for 
the following amounts: (a) any Rent of any kind whatsoever which may have 
become due with respect to the period in the Term which has already expired, 
(b) all Rent which becomes due during the remainder of the Term, (c) all 
costs, fees and expenses incurred by Landlord in leasing the Premises to 
others from time to time, including but not limited to leasing commissions, 
construction and other build-out costs, design and permitting costs and the 
like, and (d) all costs, fees and expenses incurred by Landlord in pursuit of 
its remedies hereunder, including but not limited to attorneys' fees and 
court costs. All such amounts shall be due and payable immediately upon 
demand by Landlord and shall bear interest at 18% per annum until paid. 
Furthermore, at Landlord's option, Tenant shall be obligated to pay, in lieu 
of item (b) above in this Section 14.04, an amount (the "Substitute Amount") 
which is equal to the present value of all Rent which would become due during 
the remainder of the Term, including all Additional Rent which shall be 
deemed to continue and increase over such remainder of the Term at the 
average rate of increase occurring over the then-expired portion of the Term, 
with such present value to be determined by discounting at an annual rate of 
interest which is equal to 5%. Provided that the Substitute Amount is 
actually paid in full to Landlord and the Premises are surrendered by Tenant, 
Landlord shall affirmatively list the Premises with its broker as available 
for lease (to the extent Landlord's contract with such broker does not 
already apply to all vacant space at the Building), and Tenant shall receive 
a reduction and reimbursement of all such amounts which is equal to the 
amount of any rent actually received from others to whom the Premises may be 
rented during the remainder of the original Term. Tenant and Landlord 
acknowledge and agree that payment to Landlord of the foregoing Substitute 
Amount, together with the corresponding reduction by reimbursement to Tenant 
of any rent paid by substitute tenants, are a reasonable forecast of the 
actual damages which will be suffered by Landlord in case of an Event of 
Default by Tenant, which actual damages are otherwise difficult or impossible 
to ascertain, and therefore such payment and reimbursement together 
constitute liquidated damages and not a penalty. Any suit or action brought 
by Landlord to collect any such liquidated damages shall not in any manner 
prejudice any other rights or remedies of Landlord hereunder.

    SECTION 14.05 LANDLORD'S LIEN.

    Tenant hereby grants to Landlord an express first and prior contract lien 
and security interest on all fixtures, equipment, inventory and other 
property which may be placed in the Premises or affixed or attached thereto 
and also upon all proceeds of any insurance which may be issued on account of 
damage to any such property. All exemption laws are hereby waived in favor of 
said lien and security interest benefiting Landlord. This lien and security 
interest is given in addition to any statutory lien benefiting Landlord and 
shall be cumulative thereto or alternative thereto as elected by Landlord at 
any time. If requested by Landlord, Tenant shall execute, deliver to Landlord 
and/or file at Tenant's expense with the public records Uniform Commercial 
Code financing statements in sufficient form to perfect the security interest 
hereby given.


                                     -14-


Landlord shall, in addition to all of its rights under the Lease, also have 
all of the rights and remedies of a secured party under the Uniform 
Commercial Code of the state in which the Premises are located.

    SECTION 14.06 WAIVER OF JURY TRIAL.

    All parties hereto, both the Landlord and Tenant as principals and any 
guarantors, hereby release and waive any and all rights provided by law to a 
trial by jury in any court or other legal proceeding initiated to enforce the 
terms of this Lease, involving any such parties, or connected in any other 
manner with this Lease.
