Inc. (the "Company") as of June 30, 1998 and for the three months ended June 30,
1998 and 1997 were prepared by the Company without audit in accordance with
generally accepted accounting principles for interim financial information and
in accordance with the instructions to Form 10-QSB and of the Securities and
Exchange Commission. Certain information and footnote disclosures normally
included in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to such rules and
regulations. In the opinion of management, all necessary adjustments to the
financial statements have been made to present fairly the financial position and
results of operations and cash flows of the Company. The results of operations
for the periods presented are not necessarily indicative of the results for the
respective complete years. For further information, refer to the consolidated

Earnings per share is computed based on the weighted average number of shares of
common stock and common stock equivalent shares outstanding during each period.
Common stock equivalent shares consist primarily of stock options that have a
dilutive effect when applying the treasury stock method.  The weighted average
number of shares outstanding were 6,974,653 and 5,428,724 at June 30, 1998 and
1997, respectively.

Reclassifications

Certain reclassifications, none of which affect net income, have been made to
the prior periods' amounts in order to conform to the current presentation.

2.   TERMINATION BENEFITS, IMPAIRMENT CHARGES AND ASSET WRITE-DOWNS

In April 1998, the Company's Board of Directors and management decided to close
its Utah operating facility, discontinue all activities related to the
industrial and scientific lines of business, and move its headquarters to
Pennsylvania.  As a result of the Company's decision to relocate its operations
to Pennsylvania and to focus exclusively in the dental whitening market, nearly
all of the Company's workforce of 63 employees in Utah was scheduled for
termination.  The plan of termination is expected to be completed by September
30, 1998 and a termination benefits liability of $200,000 was established and
charged to expense during the three months ended June 30, 1998.  As of June 30,
1998, the Company had terminated 50 employees and paid termination benefits of
approximately $100,000.

During the three months ended June 30, 1998, the Company has recorded additional
charges of $891,000 related to the impairment and write-down of certain assets
which will provide limited or no future benefits to the Company.  These charges
include the following:  (i) $324,000 write-down of fixed assets;  (ii) $213,000
write-down of aged accounts receivable; and (iii) $354,000 write-down of
inventories which were rendered obsolete or discontinued by the Company that
were either scrapped or sold at substantially reduced values.  The inventory
write-downs have been classified as cost of products sold - inventory write-
downs.

RESULTS OF OPERATIONS

QUARTER ENDED JUNE 30, 1998 (FISCAL 1999) VS. QUARTER ENDED JUNE 30, 1997
(FISCAL 1998)

Net Sales
- ---------

Sales for the fiscal 1999 quarter totaled $360,000 compared to $2,020,000 in the
fiscal 1998 quarter, a decrease of approximately $1,660,000 or 82%.  The
decrease in sales was due to the fact that the Company had no sales of the arc
lamp tooth whitening (TW) system in the fiscal 1999 quarter and has discontinued
all development work on the arc lamp TW system. However, management anticipates
the introduction of a new Light Activated Tooth Whitening (LATW) Device,
BriteSmile 2000, during the second half of its 1999 fiscal year.

Sales of tooth whitening chemical products declined from $344,000 in the fiscal
1998 quarter to $191,000 in the fiscal 1999 quarter due to the termination of
marketing efforts from Utah.  Marketing has been moved to Pennsylvania and sales
of tooth whitening chemical products are expected to improve.

Cost of Sales
- -------------

The Company's cost of sales, exclusive of the inventory write-downs,  increased
from 58% of sales in the fiscal 1998 quarter to 78% of sales in the fiscal 1999
quarter. The increase is due to the reduced sales of the higher margin laser
tooth whitening systems, as well as increased warranty costs as a percentage of
sales.

Selling & Administrative Expenses
- ---------------------------------

Selling and administrative expenses increased from approximately 39% of sales in
the fiscal 1998 quarter  to 244% of sales in the 1999 fiscal quarter.  This
increase is mostly attributable to the decline in sales.

Research & Development Expenses
- -------------------------------

Research and development expenses were $239,000 in the fiscal 1999 quarter
compared with $135,000 in the fiscal 1998 quarter.  This increase of $104,000 is
largely attributable to the research and development on the LATW Device,
BriteSmile 2000, which is expected to be introduced later in the current fiscal
year.  During the 1999 fiscal quarter, the Company  established a new research
and development facility in Evanston, Illinois.  The research and development
team is currently focused on the development of a new Light Activated Tooth
Whitening Device, BriteSmile 2000. Management anticipates research and
development expenditures to continue at rates at least comparable to prior
years.

Termination Benefits, Impairment Charges and Asset Write-Downs
- --------------------------------------------------------------

In April 1998, the Company's Board of Directors and management decided to close
its Utah operating facility, discontinue all activities related to the
industrial and scientific lines of business, and move its headquarters to
Pennsylvania.  As a result of the Company's decision to relocate its operations
to Pennsylvania and to focus exclusively on the dental whitening market, nearly
all of the Company's 63 employees located in Utah were scheduled for
termination.  The plan of termination is expected to be completed by September
30, 1998 and a termination benefits liability of $200,000 was established and
charged to expense during the fiscal 1999 quarter.  As of June 30, 1998, the
Company had terminated 50 employees and paid termination benefits of
approximately $100,000.

During the fiscal 1999 quarter, the Company has recorded additional charges of
$891,000  related to the impairment and write-down of certain assets which
will provide limited or no future benefit to the Company.  Included in the
charges were the following:  (i) $324,000 write-down of fixed assets; (ii)
$213,000 write-down of aged accounts receivable; and (iii) $354,000 write-down
of inventories which were  rendered obsolete or discontinued by the Company and
either scrapped or sold at substantially reduced values.  The inventory write-
downs have been classified as cost of products sold--inventory write-downs.

Income Taxes
- ------------

The Company had no income tax expense during fiscal 1998 due to its operating
loss.  Furthermore, no income tax benefit was recognized due to the uncertainty
associated with the Company's ability to realize its deferred assets, comprised
primarily of net operating loss carryforwards.

Inflation
- ---------

The Company actively strives to contain costs on parts from suppliers by
renegotiating purchase order contracts.  Inflation has not been a major factor
in the past and is not seen as a major factor that will impact the Company'
operations in the immediate future.

Net Income (Loss)
- -----------------

For the 1998 fiscal quarter, the Company incurred a net loss of $77,000 compared
to a loss of $2,115,000 for the 1999 fiscal quarter, of which $1,091,000 was due
to termination benefits, impairment charges and asset write-downs.  The
operating loss is due in large part to lower sales during the current fiscal
year as well as increased  research and development costs.


LIQUIDITY AND CAPITAL RESOURCES

The Company's financing activities resulted in an increase of $4,897,000 due
primarily to the $5,000,000 of equity capital capital raised in May, 1998.  This
increase was offset by the $1,476,000 of cash used by operating activities.

At March 31, 1998, the Company had outstanding purchase orders to acquire up to
approximately $2 million of inventory and supplies over an 18 month period.  In
connection with the reduced level of operations, management has been attempting
to cancel these orders.  As of July 31, 1998, the outstanding purchase orders
were approximately $750,000.

In this section, the term "Current Ratio" means current assets divided by
current liabilities.  "Working Capital" means current assets less current
liabilities.

                                       8
<PAGE>
 
The Company's Current Ratio and Working Capital at June 30, 1998 and March 31,
1998 were as follows:

 
                               June 30, 1998    March 31, 1998 
                               -------------    -------------- 
Current Ratio                           4.28              1.63 
Working Capital                   $4,552,000        $1,197,000  


In May, 1998, the Company completed a private placement of its common stock in
which it obtained proceeds of approximately $5,000,000.  As a result of the
curtailment of operations in Salt Lake City and reduced scope of operations,
the Company believes that cash on hand, cash flow from sales and amounts
generated through sale of certain assets will be sufficient to meet the
Company's needs for the next twelve months.

RECENT ACCOUNTING PRONOUNCEMENTS

During 1997, the Financial Accounting Standards Board issued SFAS No. 130,
Reporting Comprehensive Income.  This Standard will become effective for the
Company's 1999 fiscal year.  SFAS No. 130 establishes standards for reporting
and display of comprehensive income and its components in a full set of general-
purpose financial statements.  Management is currently assessing the impact of
implementation of this Standard on the consolidated financial statements of the
Company and does not believe that the implementation will have a material impact
on the Company's financial statements.

YEAR 2000

Many computer systems experience problems handling dates beyond the year 1999.
This is referred to widely as the "Year 2000" issue.  As a result of the May
1998 closure of its Salt Lake City manufacturing facility and downsizing of its
operations, the potential impact of the Year 2000 issue on the Company is
greatly reduced.  Additionally, the Company is in the process of upgrading its
primary financial and management systems, which upgrades are planned to be Year
2000 compliant.  The Company continues to evaluate the Year 2000 exposures
presented by its significant suppliers and other vendors whose systems may
impact the Company's operations.  However, based on the significant reduction in
operations noted above, management believes that the Year 2000 issue will not
have a material impact on the Company's operations.

  a.  "As-Is".  Tenant is leasing the Demised Premises on as "As-Is" basis,
      -------                                                              
except for the improvements provided by Landlord as noted on the attached Scope
of Work (Exhibit "B") dated May 27, 1998.  Tenant represents that it has
inspected the Demised Premises and is satisfied with its present condition.
Tenant agrees that it will be responsible to pay all costs for repair and
maintenance of the Demised Premises from the date of execution of this Lease,
including maintenance and repair of the interior plumbing, electricity, hot
water and HVAC systems in the Demised Premises.

  b.  Landlord's Work.  Utilizing a general contractor selected by Landlord,

to make substitutions of material of equivalent grade and quality when and if
any specified material shall not be readily and reasonably available, and (2) to
make changes necessitated by conditions met in the course of construction,
provided that Tenant's approval of any change shall first be obtained (which
approval shall not be unreasonably withheld) so long as there shall be general
conformity with Tenant's Improvement Plans and Tenant's intended use of the
Demised Premises and which approval must be given or denied (with reasons stated
in the case of denial) within forty-eight (48) hours after request or approval
shall be conclusively deemed to

      ----------------------------                                          
possession of the Demised Premises on the date of the commencement of the
Demised Term by reason of the holding over of a previous occupant, or by reason
of any cause beyond the control of the Landlord, or because the Demised Premises
is located in a building being constructed and which has not been sufficiently
completed to make the property ready for occupancy, or because a certificate of
occupancy has not been procured, or for any other reason, the Landlord shall not
be subject to any liability for such inability to give possession; under such
circumstances the payment of rent shall not commence until possession of the
Demised Premises is given to or the Demised Premises is available for occupancy
by the Tenant.  The failure to give possession on the date of commencement of
the Demised Term shall not affect the validity of this Lease or the obligations
of the Tenant hereunder, or extend the Demised Term, provided, however, in the

Tenant shall have the option of declaring the Lease terminated by giving
Landlord written notification thereof by registered mail on or before August 30,

  7.  Additional Rent.
      --------------- 

  (a)  Breach.  Tenant agrees to pay as rent in addition to the Basic Rent any
       ------                                                                 
and all sums which may become due by reason of the failure of Tenant to comply
with all of the covenants of this Lease and any and all damages, costs and
expenses, including attorney's fees, which the Landlord may suffer or incur by
reason of such default, and also any and all damages to the Demised Premises
caused by any act or neglect of the Tenant.

  (b)  Taxes, Assessments, Etc.  Tenant will duly promptly pay as additional
       ------------------------                                             
rent to Landlord, as the same shall become due and payable and before they
become delinquent, all taxes, rates, assessments and other governmental charges,
and charges of every kind and nature whatsoever, nonrecurring as well as
recurring, special or extraordinary as well as ordinary, foreseen and
unforeseen, and each and every installment thereof, which shall or may during
the term of the Lease be levied, assessed or imposed, or become due and payable
or become liens upon, or arise in connection with the use, occupancy or
possession of, or any interest in, the Demised Premises, or upon the rents,
issues, income and profits therefrom so as to prevent the same from becoming or
being an enforceable lien or claim against the property or the interest of
Landlord ("Expenses").  Landlord shall apply such payment by Tenant to the
payment of such Expenses, but in no event shall Landlord be required to pay such
Expenses early or during discount periods.  Such Expenses shall include all real
estate taxes, assessments, water and sewer charges which may become liens upon
the Demised Premises or any part thereof.  If Landlord requests Tenant to pay
such Expenses other than to Landlord, Tenant will furnish or cause to be
furnished to Landlord not less than fifteen (15) days prior to the date on which
payment of the same would become delinquent, or subject to penalty or interest,
receipts or other evidence satisfactory to Landlord of the payment of all such
Expenses.  If Landlord requests in writing, Tenant shall pay to Landlord, or as
Landlord may direct, such Expenses in advance in installments as estimated and
determined by Landlord, and deposited with Landlord, or as directed by Landlord,
for payment of all such Expenses when the same may become due and payable.
Notwithstanding the foregoing, Tenant shall not be responsible for gross

                                       3
<PAGE>
 
receipts or other income taxes incurred by Landlord on the rents received
hereunder unless it is imposed in lieu of another charge for which Tenant is
responsible hereunder.

  If the Tenant deems excessive or illegal any such Expenses, with the written
consent of the Landlord, the Tenant may make payment under protest.  Any
contest, whether before or after payment, may be made in the name of the
Landlord or the Tenant or both, with the written consent of the Landlord.  If
requested by Tenant, Landlord may, but shall not be required to participate in
any such contest, but the Tenant shall be entitled to any refund of any such
Expenses, and any penalty or interest thereon which may have been paid by the
Tenant, but all costs in connection with such contest shall be borne by the
Tenant.

  In case of failure of the Tenant to make any of the payments to be made by
Tenant for such Expenses, the Landlord may, but shall not be required to, pay
the amount of same, with penalty and interest thereon, if any.  The amount so
paid by the Landlord, with interest thereon from the date of payment thereof by
the Landlord, shall be added to and become a part of the next installment of
rent.

  If at any time during the term of this Lease the methods of taxation
prevailing at the commencement of the term hereof shall be altered so that in
lieu of or as a supplement to or a substitute for the whole or any part of the
real estate taxes or assessments now levied, assessed or imposed (1) a tax,
assessment, levy, imposition or charge, wholly or partially as a capital levy or
otherwise, on the rents received therefrom or (2) a tax, assessment, levy
(including but not limited to any municipal, state or federal levy), imposition
or charge measured by or based in whole or in part upon the premises and imposed
upon the Landlord, or (3) a license fee measured by the rent payable under this
Lease, then all such taxes, assessments, levies or impositions and charges, or
the part thereof so measured or based shall be deemed to be included in the
general real estate taxes and assessments payable by the Tenant pursuant hereto
to the extent that such taxes, assessments, levies, impositions and charges
would be payable if the premises were the only property of the Landlord subject
thereto, and the Tenant shall pay and discharge the same as herein provided in
respect of the payment of general real estate taxes and assessments.

  (c)  Insurance.  Landlord shall keep all buildings and improvements now or
       ---------

against loss by fire and other casualties and hazards usually covered by
extended coverage insurance in an amount not less than the replacement value of
the Demised Premises (excluding foundations and other parts below the surface of
the lowest floor), as determined not more than once annually by an appraiser or
rating bureau satisfactory to Landlord.  Tenant agrees that it will, throughout
the Demised Term, pay and discharge as additional rent, the cost incurred by
Landlord in insuring the Demised Premises as above stated.  Insurance premiums
at the beginning and end of the term shall be apportioned. It is expressly
understood and agreed that if for any reason attributable to Tenant it shall be
impossible to obtain Fire insurance on the building and improvements on the
Demised Premises in an amount and in the form and with fire insurance companies
acceptable to the Landlord, the Landlord may, if the Landlord elects, (a)
terminate this Lease and the term thereof on giving to the Tenant fifteen (15)
days' notice in writing of Landlord's intention so to do and upon the giving of
such notice this lease and the terms thereof, shall terminate and come to an

standard cost as if the condition attributable to Tenant did not exist and
Tenant shall be obligated to pay all of such additional cost.

improvements made to or inside the Demised Premises by Tenant.  Such policy
shall name as insured Landlord and Tenant, as their interests may appear and
shall name Landlord's first mortgagee, if any, as mortgagee.  A copy of such
policy shall be furnished to Landlord and Landlord's first mortgagee.

  (2)  Tenant at its own cost and expense will provide and keep in force during
the Demised Term of this Lease commercial general liability insurance covering
at least the hazards of "premises-operations", "elevators" (if applicable) and
"independent contractors", in which Landlord shall be included as a named
insured, in such other limits of liability as may be required by Landlord from
time to time, but not less than One Million Dollars ($1,000,000.00) combined
single limit, with a deductible not to exceed Five Thousand Dollars ($5,000.00).
Such insurance shall cover not only the Demised Premises but shall also include
all elevators, hoists, hallways, entranceways, stairs or any other common areas

areas, sidewalks and curbs adjacent thereto.

  (3)  All such policies shall contain provision for notice to the said Landlord
not less than ten (10) days in advance of any cancellation or material change of
such policy.  In case of failure of the Tenant to make premium payments when
due, the Landlord may pay the amount of any such premiums, which amount with
interest thereon from the date of payment by Landlord shall be added to and
become part of the next installment of rent.

  (4)  Copies of renewal policies or certificates for any insurance required
under this Paragraph shall be deposited by Tenant with Landlord at least ten
(10) days prior to the expiration of existing policies, and upon failure so to
do Landlord may immediately purchase, for the account of Tenant, the necessary
insurance from any reputable insurance company without notice to Tenant, and
Tenant shall reimburse Landlord for cost thereof within ten (10) days after
demand.

  (5)  All insurance required hereunder shall be issued by companies licensed to
do business in Pennsylvania and acceptable to Landlord.  Tenant shall have the
right to carry the insurance provided for in this Paragraph, or any portions of
such insurance under a blanket or comprehensive all-risks policy.

  (6)  Personal Property Insurance.  Tenant shall maintain, at its expense,
       ----------------------------                                        
insurance on all of its personal property, including removable trade fixtures,
located in the Demised Premises.

  (d)  Utilities.  Tenant further agrees to pay as additional rent all charges
       ---------                                                              
for water, sewer, gas, oil, electricity, light, heat, power, telephone or other
utility used by Tenant at the Demised Premises during the Demised Term.  Where

Landlord at the expense of Tenant.  All charges for installation or repairs to
the said water meter or

the right to do the following things and matters in and about the Demised
Premises:

  (a)  Inspection.  At all reasonable times by himself or his duly authorized
       ----------

  (b)  Rules and Regulations.  At any time or times and from time to time to

  (d)  Discontinuance of Facilities and Services.  The Landlord may discontinue
       -----------------------------------------                               
all facilities furnished and services rendered, or any of them by Landlord, not
expressly covenanted for herein, it being understood that they constitute no
part of the consideration for this Lease.

  12.  Responsibility of Tenant.  Landlord shall not in any event be
       ------------------------                                     
responsible, and the Tenant hereby specifically assumes responsibility for any
personal or bodily injury or death of any persons (including employees of Tenant
and Landlord) and damage, destruction, or loss of use of any property, including
the Demised Premises (except as specifically provided otherwise herein)
occasioned by any event happening on or about the Demised Premises, hallways,
entranceways, stairs or any other common areas (exterior or interior),
elevators, hoists, streets, driveways, parking and loading areas, alleys, lawns,
sidewalks and curbs adjacent thereto including those resulting from any work in
connection with any alterations, changes, new construction or demolition, except
if same results solely from the negligence of Landlord, its agents, servants, or
employees.  Tenant is subrogated to any rights of Landlord against any other
parties in connection therewith.  Tenant shall defend, indemnify and hold
harmless Landlord from and against any and all claims, demands, suits, damages,
liability and costs (including counsel fees and expenses) arising out of or in
any manner connected with any act or omission, negligent or otherwise of Tenant,
third persons, or any of their agents, servants or employees which arise out of
or are in any way connected with the erection, maintenance, use, operation,
existence or occupation of the Demised Premises, hallways, entranceways, stairs
or any other common areas (exterior or interior), elevators, hoists, streets,
driveways, parking and loading areas, alleys, lawns, sidewalks and curbs
adjacent thereto unless due solely to the negligence of Landlord, its agents,
servants or employees.

  The Landlord shall promptly notify the Tenant of any claim asserted against
the Landlord on account of any such injury or claimed injury to persons or
property and shall promptly deliver to the Tenant the original or a true copy of
any summons or other process, pleading or notice issued in any suit or other
proceeding to assert or enforce any such claim.  The Tenant shall have the right
to defend any such suit with attorneys of its own selection and the Landlord
shall have the right, if it sees fit, to participate in such defense.

  Tenant further shall defend, indemnify and hold harmless Landlord from claims,
demands, suits, liability for damages for personal or bodily injury or death of
any persons or damage or destruction of any property (including loss of use
thereof) caused by or in any manner arising out of any breach, violation or
nonperformance by Tenant of any covenant, term or provision of this Lease.

  13.  Damage to Demised Premises.
       -------------------------- 

  (a)  In the event that the Demised Premises is totally destroyed or so damaged
by fire or other casualty not occurring through fault or negligence of the
Tenant or those employed by or acting for 

                                       10
<PAGE>
 
him, that, in Landlord's judgment, the same cannot be repaired or restored
within one hundred eighty (180) days, this Lease shall absolutely cease and
determine, and the rent shall abate as of the date of casualty for the balance
of the term.

  (b)  If the damage caused as above be only partial and such that the Demised
Premises, in Landlord's judgment, can be restored within one hundred eighty
(180) days, the Landlord may, at its option, restore the same, excluding
fixtures and improvements owned by Tenant, with reasonable promptness, reserving
the right to enter upon the Demised Premises for that purpose.  The Landlord
also reserves the right to enter upon the Demised Premises whenever necessary to
repair damage caused by fire or other casualty to the building of which the
Demised Premises is a part, even though the effect of such entry be to render
the Demised Premises or a part thereof untenantable.  In either event the rent
shall be apportioned and suspended during the time the Landlord is in
possession, taking into account the portion of the Demised Premises rendered
untenantable and the duration of the Landlord's possession.  If a dispute arises
as to the amount of rent due under this clause, Tenant agrees to pay the full
amount claimed by Landlord.  Tenant shall, however, have the right to proceed by
law to recover the excess payment, if any.

  (c)  In the event that Landlord does not notify Tenant that in the Landlord's
judgement, the damage cannot be repaired within 180 days, or in the event that
Landlord fails to notify Tenant if Landlord exercises its election to repair the
damage within 180 days, then Tenant shall have the right to give notice to
Landlord, after the expiration of 30 days from the date of damage, that unless
Landlord advises Tenant within 10 days after receipt of such notice that
Landlord intends to complete the repair of the damage to the Demised Premises
within 180 days from the date of the damage, it shall be deemed conclusive that
Landlord has elected not to complete said repairs, and the Tenant may elect to
terminate the Lease, commencing the 11th day after such notice, at any time
prior to the receipt of notice from Landlord of its election to repair the
damage to the Demised Premises.

(d)  Notwithstanding the fact that Landlord may have given notice of election to
repair the Demised Premises within said thirty (30) day period, if the mortgagee
chooses to accelerate the mortgage due to damage by fire or other casualty to
the Demised Premises or the building of which the Demised Premises is a part,
Landlord shall have the right to rescind and/or cancel said election to repair
and shall have the right to elect not to repair the damaged to the Demised
Premises or the building of which the Demised Premises is a part, provided said
notification of election not to repair is given to Tenant within thirty (30)
days after date of the receipt of said notice of acceleration.

  (e)  Landlord shall not be liable for any damage, compensation or claim by
reason of inconvenience or annoyance arising from the necessity of repairing any
portion of the building, the interruption in the use of the Demised Premises, or
the termination of this Lease by reason of the destruction of the Demised
Premises.

  14.  Miscellaneous Agreements and Conditions.
       --------------------------------------- 

  (a)  Non-Waiver by Landlord or Tenant.  The failure of the Landlord or Tenant
       --------------------------------                                        
to insist 

                                       11
<PAGE>
 
upon strict performance of any of the covenants or conditions to this Lease, or
to exercise any option herein conferred in any one or more instances, shall not
be construed as a waiver or relinquishment for the future of any such covenants
or conditions of this Lease or option, but the same shall be and remain in full
force and effect.

  (b)  Accord and Satisfaction.  No payment by Tenant or receipt by Landlord of
       -----------------------                                                 
a lesser amount than the monthly rent herein stipulated shall be deemed to be
other than on account of the earliest stipulated rent, nor shall any endorsement
or statement on any check or any letter accompanying any check or payment as
rent be deemed an accord and satisfaction, and Landlord may accept such check or
payment without prejudice to Landlord's right to recover the balance of such
rent or pursue any other remedy herein.

  (c)  Jurisdiction and Law.  Tenant hereby subjects itself to the jurisdiction
       ---------------------                                                   
of the Court of Common Pleas of Delaware County, Pennsylvania.  The laws of the
Commonwealth of Pennsylvania shall be applicable to this lease and any
interpretations thereof.

  (d)  The Landlord has let the Demised Premises in its present condition and
without any representations on the part of Landlord, his officers, employees,
servants and/or agents.

  (e)  In the event that it is determined at any time during the Demised Term of
this Lease and any renewal period that the Tenant's proposed use of the Demised
Premises as set forth in Paragraph 1 is not permissible under the local Zoning
Ordinance or Regulations, then Tenant shall have the privilege of terminating
this Lease on the last day of any month thereafter, provided that at least sixty
(60) days prior to the termination date notice is given to Landlord in writing
and such privilege shall be Tenant's sole remedy against Landlord in such event.

  15.  Remedies of Landlord.  If the Tenant:
       --------------------                 

  (a)  Does not pay within five (5) days after it is due any and all
installments of rent and/or any other charge or payment herein reserved,
included, or agreed to be treated or collected as rent and/or any other charge,
expense, or cost herein agreed to be paid by the Tenant; or

  (b)  Violates or fails to perform or otherwise breaks any non-monetary
covenant or agreement herein contained which is not corrected in compliance
within twenty (20) days after the notice; or

  (c)  Vacates the Demised Premises or removes or attempts to remove or
manifests an intention to remove any goods or property therefrom otherwise than
in the ordinary and usual course of business without having first paid and
satisfied the Landlord in full for all rent and other charges then due; or

  (d)  Files or has filed against it (and if against not dismissed in thirty
(30) days) a petition under Title 11, United States Code, Bankruptcy, as now or
hereafter amended or supplemented, whether 

                                       12
<PAGE>
 
under Chapter 7, 11 or 13 of the aforesaid Bankruptcy Code; or if there is the
commencement of any action or proceeding under state or federal law for the
dissolution or liquidation of the Tenant in connection with bankruptcy or other
insolvency, whether instituted by or against (and if against not dismissed in
thirty (30) days) the Tenant or for the appointment of a receiver or trustee of
all or substantially all of the property of the Tenant; or if there is the
taking of possession of the property of the Tenant by any governmental officer
or agency pursuant to statutory authority for the dissolution, rehabilitation,
reorganization or liquidation of the Tenant; or if there is the making by the
Tenant of an assignment for the benefit of creditors;

  Then and in any of said events, there shall be deemed to be a breach of this
Lease, and thereupon Landlord shall have the following rights:

  (1)  To accelerate the whole or any part of the Basic Rent and additional rent
(sometimes collectively referred to herein as "Rent") and other charges,
payments, costs and expenses herein agreed to be paid by Tenant for the entire
unexpired balance of the term of this Lease, and any Rent, other charges,
payments, costs and expenses if so accelerated shall, in addition to any and all
installments of Rent already due and payable and in arrears, and/or any other
charge, expense or cost herein agreed to be paid by Tenant which may be due and
payable and in arrears, be deemed due and payable as if, by the terms and
provisions of this Lease, such accelerated Rent and other charges, payments,
costs and expenses were on that date payable in advance.

  (2)  To enter the Demised Premises and without further demand or notice
proceed to distrain and sell the goods and personal property there found, to
levy the Rent and Tenant shall pay all costs and officers' commissions,
including watchmen's wages and sums chargeable to Landlord, and further
including the five percent (5%) chargeable by the Act of Assembly as commissions
to the constable or other person making the levy, and in such case all costs,
officers' commissions and other charges shall immediately attach and become part
of the claim of Landlord for Rent, and any tender of rent without said costs,
commissions and charges made, after the issuance of a warrant of distress, shall
not be sufficient to satisfy the claim of Landlord.  Tenant specifically waives
any requirement of notice before distraint.

  (3)  To re-enter the Demised Premises and remove all persons and all or any
property therefrom, either by summary dispossess proceedings or by any suitable
action or proceeding at law, or by force or otherwise, without being liable to
indictment, prosecution or damages therefor, and repossess and enjoy the Demised
Premises, together with all alterations, fixtures, signs and other installations
of Tenant.  Upon recovering possession of the Demised Premises by reason of or
based upon or arising out of a default on the part of Tenant, Landlord may, at
Landlord's option, either terminate this Lease or make such alterations and
repairs as may be necessary in order to relet the Demised Premises and relet the
Demised Premises or any part or parts thereof, either in Landlord's name or
otherwise, for a term or terms which may at Landlord's option be less than or
exceed the period which would otherwise have constituted the balance of the term
of this Lease and at such rent or rents and upon such other terms and conditions
as in Landlord's sole discretion may seem advisable and to such person or
persons as may in Landlord's discretion seem best; upon each such reletting all
rents received by Landlord from such reletting shall be applied: first, to the
payment of any indebtedness other than rent due hereunder from 

                                       13
<PAGE>
 
Tenant to Landlord; second, to the payment of any costs and expenses of such
reletting, including brokerage fees and attorney's fees and all costs of such
alterations and repairs; third, to the payment of Rent due and unpaid hereunder;
and the residue, if any, shall be held by Landlord and applied in payment of
future Rent as it may become due and payable hereunder. If such rentals received
from such reletting during any month shall be less than that to be paid during
that month by Tenant hereunder, Tenant shall pay any such deficiency to
Landlord. Such deficiency shall be calculated and paid monthly. No such re-entry
or taking possession of the Demised Premises or the making of alterations and/or
improvements thereto or the reletting thereof shall be construed as an election
on the part of Landlord to terminate this Lease unless written notice of such
intention be given to Tenant. Landlord shall in no event be liable in any way
whatsoever for failure to relet the Demised Premises or, in the event that the
Demised Premises or any part or parts thereof are relet, for failure to collect
the rent thereof under such reletting. Tenant, for Tenant and Tenant's
successors and assigns, hereby irrevocably constitutes and appoints Landlord as
Tenant's and Landlord's agent to collect the rents due and to become due under
all subleases of the Demised Premises or any parts thereof without in any way
affecting Tenant's obligation to pay any unpaid balance of Rent due or to become
due hereunder. Notwithstanding any such reletting without termination, Landlord
may at any time thereafter elect to terminate this Lease for such previous
breach.

  (4)  To terminate this Lease and the term hereby created without any right on
the part of Tenant to waive the forfeiture by payment of any sum due or by other
performance of any condition, term or covenant broken.  Whereupon Landlord shall
be entitled to recover, in addition to any and all sums and damages for
violation of Tenant's obligations hereunder in existence at the time of such
termination, damages for Tenant's default in an amount equal to the greater of
(i) amount of the Rent reserved for the balance of the Demised Term, as well as
all other charges, payments, costs and expenses herein agreed to be paid by
Tenant, all discounted at the rate of nine percent (9%) per annum to their then
present worth, less the fair rental value of the Demised Premises for the
remainder of said term, also discounted at the rate of nine percent (9%) per
annum to its then present worth or (ii) three (3) months' rent, all of which
amount shall be immediately due and payable from Tenant to Landlord as
liquidated damages.

  (5)  If Tenant shall default in the payment of the Rent reserved or in the
payment of any other sums due hereunder by Tenant, Tenant hereby authorizes and
empowers any Prothonotary or attorney of any court of record to appear for
Tenant in any and all actions which may be brought for said Rent and/or said
other sums and to confess judgement against Tenant for all or any part of said
Rent and/or said other sums, including but not limited to the amounts due from
Tenant to Landlord under subsections (1), (2), (3) and/or (4) of this section;
and for interest and costs, together with an attorney's commission for
collection of ten percent (10%).  The right to institute an action pursuant to
Pennsylvania Rules of Civil Procedure and the authority to confess judgement
granted herein shall not be exhausted by one or more exercises thereof, so long
as each exercise refers or relates to separate sums, and successive complaints
may be filed and successive judgements may be entered from time to time for
separate sums as aforedescribed, as or after they become due, as well as after
the expiration of the original term and/or during or after expiration of any
extension or renewal of this Lease.

  (6)  When this Lease and the term or any extension or renewal thereof shall
have been terminated on account of any default by Tenant hereunder, and also
when the term hereby created 

                                       14
<PAGE>
 
or any extension or renewal thereof shall have expired, it shall be lawful for
any attorney of any court of record to appear as attorney for Tenant as well as
for all persons claiming by, through or under Tenant, and to sign an agreement
for entering in any competent court a confession of judgement in ejectment
against Tenant and all persons claiming by, through or under Tenant and therein
confess judgement for the recovery by Landlord of possession of the Demised
Premises, for which this Lease shall be his sufficient warrant; thereupon, if
Landlord so desires, an appropriate writ of possession may issue forthwith,
without any prior writ or proceeding whatsoever, and provided that if for any
reason after such action shall have been commenced it shall be terminated and
possession of the Demised Premises remain in or be restored to Tenant, Landlord
shall have the right for the same default and upon any subsequent default or
defaults, or upon the termination of this Lease or Tenant's right of possession
as hereinbefore set forth, to bring one or more further confession of judgement
actions as hereinbefore set forth to recover possession of the Demised Premises.

  (7)  In any confession of judgement of ejectment and/or for rent and/or other
sums brought hereon, Landlord shall first cause to be filed in such action an
affidavit made by Landlord or someone acting for Landlord, setting forth the
facts necessary to authorize the entry of judgement of which facts such
affidavit shall be prima facie evidence, and if a true copy of this Lease (and
of the truth of the copy such affidavit shall be sufficient evidence) shall be
filed in such suit, action or actions, it shall not be necessary to file the
original as a warrant of attorney, any rule of Court, custom or practice to the
contrary notwithstanding.

  16.  Right of Injunctive Relief.  In the event of a breach or threatened
       --------------------------                                         
breach by Tenant of any of the covenants or provisions hereof, Landlord shall
have the right of injunction and the right to invoke any remedy allowed at law
or in equity as if re-entry, summary proceedings and other remedies were not
herein provided for.

  17.  Rights Not Exclusive.  No right or remedy herein conferred upon or
       --------------------                                              
reserved to Landlord is intended to be exclusive of any other right or remedy
herein or by law provided but each shall be cumulative and in addition to every
other right or remedy given herein or now or hereafter existing at law or in
equity or by statute.
 
  18.  Waivers by Tenant.  Tenant expressly waives:
       -----------------                           

  (a)  The benefit of all laws, now or hereafter in force, exempting any goods
on the Demised Premises or elsewhere from distraint, levy or sale in any legal
proceedings taken by Landlord to enforce any rights under this Lease.

  (b)  The right to ten (10) days and/or fifteen (15) or thirty (30) days'
notice required under certain circumstances by The Landlord and Tenant Act of
1951, as amended in 1995, Tenant hereby agreeing that seven (7) days' notice
shall be sufficient in either or any such case.

  19.  Calculations of Amounts Due.  For the purpose of calculating the
       ---------------------------                                     
accelerated Rent payable under paragraph (1) of Paragraph 15 (d) of this Article
and the "Rent reserved for the balance of the term" 

                                       15
<PAGE>
 
of this Lease for the purposes of Paragraph (4) of Paragraph 15 (d) of this
Article, the amount payable as Tenant's share of real estate taxes, Tenant's
share of the cost of insurance on the Demised Premises and Tenant's share of
common area maintenance expenses and any other charges for which Tenant is
responsible hereunder for the balance of the term hereof shall be equal to the
sum of the highest amount paid or payable by Tenant in any calendar year for
each of the foregoing items multiplied by the number of calendar years
(including any fractional calendar year) remaining in the term of this Lease.

  20.  Right of Assignee of Landlord.  The right to pursue the remedies herein
       -----------------------------                                          
provided against Tenant and to enforce all of the other provisions of this Lease
may, at the option of any assignee of this Lease, be exercised by any assignee
of the Landlord's right, title and interest in this Lease in his, her or their
own name, any statute, rule of court, custom, or practice to the contrary
notwithstanding.

  21.  Remedies Cumulative.  All of the remedies hereinbefore given to Landlord
       -------------------                                                     
and all rights and remedies given to it by law and equity shall be cumulative
and concurrent.  No termination of this Lease or the taking or recovering of the
Demised Premises shall deprive Landlord of any of its remedies or actions
against Tenant for rent or sums due at the time or which, under the terms
hereof, would in the future become due as if there has been no termination; nor
shall the bringing of any action for rent or breach of covenant, or the resort
to any other remedy herein provided for the recovery of rent be construed as a
waiver of the right to obtain possession of the premises.

  22.  Condemnation.  If at any time during the Demised Term or any renewal or
       ------------                                                           
extension thereof the Demised Premises, or any portion thereof, be lawfully
condemned or conveyed in lieu of condemnation, the Landlord shall be entitled
to, and shall receive the award or payment therefor, and the Tenant shall
assign, and does hereby assign and transfer to the Landlord such award or
payment as may be made therefor.  Tenant, however, shall be entitled to make a
claim for damages payable specifically and solely to a business Tenant under the
terms of the Eminent Domain Code of Pennsylvania, Act of June 22, 1964, P.L. 84,
as now or hereafter amended, provided that any award to Tenant shall not in any
way diminish the Landlord's award.  This Lease shall, as to the part so taken
terminate as of the date title shall vest in the condemnor, and rent shall abate
in proportion to the square feet of the leased space taken or condemned.  In the
event, however, that more than thirty percent (30%) of the Demised Premises
(exclusive of Common Areas) is taken,  Tenant shall have the option of
terminating this Lease upon thirty (30) days prior written notice to Landlord.

  23.  Execution of Estoppel Certificate.  At any time, and from time to time,
       ---------------------------------                                      
upon the written request of Landlord or any first mortgagee, Tenant within
twenty (20) days of the date of such written request agrees to execute and
deliver to Landlord and/or such first mortgagee, without charge and in a form
satisfactory to Landlord and/or such mortgagee, a written statement: (a)
ratifying this Lease; (b) confirming the commencement and expiration date of the
term of this Lease and the minimum annual rental rate payable during the lease
term; (c) certifying that Tenant is in occupancy of the Demised Premises, and
that the Lease is in full force and effect and has not been modified, assigned,
supplemented or amended except by such writings as shall be stated; (d)
certifying that all conditions and agreements under this Lease to be satisfied
or performed by Landlord have been satisfied and performed except as shall be
stated; (e) certifying that Landlord is not in default under the Lease and there
are no defenses or offsets 

                                       16
<PAGE>
 
against the enforcement of this Lease by Landlord or stating the defaults and/or
defenses claimed by Tenant; (f) reciting the amount of advance rent, if any,
paid by Tenant and the date to which such rent has been paid and, if requested
by Landlord and/or Mortgagee, agreeing that Tenant shall not pay rent to
Landlord more than thirty days in advance; (g) reciting the amount of security
deposited with Landlord, if any; (h) certifying that Tenant has no option or
right of first refusal to purchase the Demised Premises or option to extend the
term of the Lease (unless specifically set forth to the contrary in the Lease);
(i) if requested by Landlord and/or Mortgagee, agreeing that the Lease will not
be modified without the prior written consent of the Mortgagee; (j) certifying
that tenant will not generate, store, handle or otherwise deal with any amount
of any hazardous substances or hazardous waste (as defined in federal, state and
local law) in or about the Demised Premises, in excess of those levels or
quantities specified for regulatory purposes; (k) agreeing, if requested by
Mortgagee, that Tenant will give Mortgagee such notice of any default by
Landlord and reasonable opportunity to cure such default, not in excess of
thirty (30) days, unless the default cannot be cured within said time, before
exercising Tenant's remedies under the Lease; and (l) any other information
which Landlord or the mortgagee shall require.

  24.  Failure to Execute Estoppel Certificate.  The failure of Tenant to
       ---------------------------------------                           
execute, acknowledge and deliver to Landlord and/or any first mortgagee a
statement in accordance with the provisions of Paragraph 23 above within the
said twenty (20) day period shall constitute acknowledgement by Tenant which may
be relied upon by any person holding or intending to acquire any interest
whatsoever in the Demised Premises that this Lease has not been assigned,
amended, changed, or modified, is in full force and effect and that the Basic
Rent and additional rent have been duly and fully paid not beyond the respective
due dates immediately preceding the date of the request for such statement and
shall constitute as to any persons entitled to rely on such statements a waiver
of any defaults by Landlord or defenses or offsets against the enforcement of
this Lease by Landlord which may exist prior to the date of the written request,
and Landlord at its option, may treat such failure as a deliberate event of
default.

  25.  Subordination and Attornment.  Tenant agrees:
       ----------------------------                 

  (a)  that, except as hereinafter provided, this Lease is, and all of Tenant's
rights hereunder are and shall always be, subject and subordinate to any first
mortgage ("First Mortgage"); and

  (b)  That if the holder of any such First Mortgage ("Mortgagee") or if the
purchaser at any foreclosure sale or at any sale under a power of sale contained
in any Mortgage shall at its sole option so request, Tenant will attorn to, and
recognize such mortgagee or purchaser, as the case may be as Landlord under this
Lease for the balance then remaining of the term of this Lease, subject to all
terms of this Lease; and

  (c)  That the aforesaid provisions shall be self-operative and no further
instrument or document shall be necessary unless required by any such First
Mortgagee or purchaser.  Notwithstanding anything to the contrary set forth
above, any First Mortgagee may at any time subordinate its Mortgage to this
Lease, without Tenant's consent, by notice in writing to Tenant, and thereupon
this Lease shall be deemed prior to such Mortgage without regard to their
respective dates of execution, delivery and/or recording and in that event such
First Mortgagee shall have the same rights with respect to this Lease as 

                                       17
<PAGE>
 
though this Lease had been executed and a memorandum thereof recorded prior to
the execution, delivery and recording of the Mortgage and as though this Lease
had been assigned to such First Mortgagee. Should Landlord or any First
Mortgagee or purchaser desire confirmation of either such subordination or such
attornment, as the case may be, Tenant upon written request, and from time to
time, will execute and deliver without charge and in form satisfactory to
Landlord, the First Mortgagee or the purchaser all instruments and/or documents
that may be requested to acknowledge such subordination and/or agreement to
attorn, in recordable form.

  26.  Failure to Execute Instruments and Documents.  In the event Tenant fails
       --------------------------------------------                            
to execute and deliver the instruments and documents as provided for in
Paragraphs 23 and 26 within twenty (20) days after request in writing by
Landlord or such First Mortgagee or purchaser, as the case may be, Tenant does
hereby make, constitute and appoint Landlord or such First Mortgagee or
purchaser, as the case may be, as Tenant's attorney-in-fact and in its name,
place and stead to do so, or Landlord may treat such failure as a deliberate
event of default.  The aforesaid power of attorney is given as coupled with an
interest and is irrevocable.

  27.  Quiet Enjoyment; Eviction by Foreclosure.  Tenant, on paying the rent
       ----------------------------------------                             
reserved, and performing all the covenants and conditions hereof, shall at all
times during the Demised Term, peaceably and quietly have, hold and enjoy the
Demised Premises; provided, however, eviction of the Tenant by reason of the
foreclosure of any First Mortgage now or hereafter on the Demised Premises shall
not be construed as a breach of this covenant, nor shall any action by reason
thereof be brought against the Landlord; and provided further, that no eviction
of the Tenant for any reason whatsoever, after the Landlord shall have conveyed
the fee of the Demised Premises shall be construed as a breach of this covenant,
and no action therefor shall be brought against the Landlord.

  28.  Termination of Lease.  It is hereby mutually agreed that either party
       ---------------------                                                
hereto may terminate this Lease at the end of the Demised Term by giving to the
other party written notice thereof at least 180 days prior thereto, but in
default of such notice, this Lease shall continue upon the same terms and
conditions in force immediately prior to the expiration of the Demised Term
hereof as are herein contained except for Basic Rent which shall be adjusted to
reflect the then current market rates for space comparable to the Demised
Premises as determined by Landlord based upon other of Landlord's rental
properties,  for a further period of one year and so on from year to year unless
or until termination by either party hereto, giving the other 180 days written
notice for removal previous to expiration of the then current term; PROVIDED,
however, that should this Lease be continued for a further period under the
terms herein-above mentioned, any allowances given Tenant on the Basic Rent
during the original term shall not extend beyond such original term.  In the
event that Tenant shall give notice, as stipulated in this Lease, of intention
to vacate the Demised Premises at the end of the Demised Term, or any renewal or
extension thereof, and shall fail or refuse so to vacate the same on the date
designated by such notice, then it is expressly agreed that Landlord shall have
the option either:

  (a)  To disregard the notice so given as having no effect, in which case all
the terms and conditions of this Lease shall continue thereafter, as set forth
above, with full force precisely as if such notice has not been given, or

                                       18
<PAGE>
 
  (b)  Landlord may, at any time within thirty days after the Demised Term or
any renewal or extension thereof, as aforesaid, give the said Tenant ten days'
written notice of his intention to terminate the said Lease; whereupon the
Tenant expressly agrees to vacate said premises at the expiration of the said
ten day period.

  All powers granted to Landlord by this lease may be exercised and all
obligations imposed upon Tenant by this Lease shall be performed by Tenant as
well during any extension of the Demised Term of this Lease as during the
Demised Term itself.

  29.  Notices.  All notices required shall be in writing given by certified
       -------

  30.  Mechanic's Liens.
       ---------------- 

  (a)  Mechanic's Liens Prohibited.  Tenant shall not suffer any mechanic's lien
       ---------------------------                                              
to be filed against the Demised Premises by reason of work, labor, services or
materials performed or furnished to Tenant or anyone holding the Demised
Premises, or any part hereof, through or under Tenant.  If any mechanic's lien
or any notice of intention to file a mechanic's lien shall at any time be filed
against the Demised Premises Tenant shall at Tenant's cost, within fourteen (14)
days after knowledge or notice of the filing of any mechanic's lien cause the
same to be removed or discharged of record by payment, bond, order of a court of
competent jurisdiction, or otherwise.

  (b)  Landlord's Remedy for Tenant's Breach.  If Tenant shall fail to remove or
       -------------------------------------                                    
discharge any mechanic's lien or any notice of intention to file a mechanic's
lien within the prescribed time, then in addition to any other right or remedy
of Landlord, Landlord may, at its option, procure the removal or discharge of
the same by payment or bond or otherwise.  Any amount paid by Landlord for such
purpose, 

                                       19
<PAGE>
 
together with all legal and other expenses of Landlord in procuring the
removal or discharge or such lien or notice of intention and together with
interest thereon at the highest permissible rate shall be and become due and
payable by Tenant to Landlord as additional rent, and in the event of Tenant's
failure to pay therefor within fifteen (15) days after demand, the same shall be
added to and be due and payable with the next month's rent.

  (c)  Non-Consent of Landlord to Filing of Liens.  Nothing contained in this
       ------------------------------------------                            
Lease shall be construed as a consent on the part of Landlord to subject
Landlord's estate in the Demised Premises to any lien or liability arising out
of Tenant's use or occupancy of the premises.

  31.  Lease Contains All Agreements.  It is expressly understood and agreed by
       -----------------------------                                           
and between the parties hereto that this Lease sets forth all the promises,
agreements, and conditions or understandings between Landlord or his Agent and
Tenant relative to the Demised Premises, and that there are no promises,
agreements, conditions or understandings, either oral or written, between them
other than are herein set forth.  It is further understood and agreed that,
except as herein otherwise provided, no subsequent alteration, amendment, change
or addition to this Lease shall be binding upon Landlord or Tenant unless
reduced to writing and signed by them.

  32.  Heirs and Assignees.  All rights and liabilities herein given to, or
       -------------------                                                 
imposed upon, the respective parties hereto shall extend to and bind the several
and respective heirs, executors, administrators, successors and assigns of said
parties; and if there shall be more than one Tenant, they shall all be bound
jointly and severally by the terms, covenants and agreements herein, and the
word "Tenant" shall be deemed and taken to mean each and every person or party
mentioned as a Tenant herein, be the same one or more; and if there shall be
more than one Tenant, any notice required or permitted by the terms of this
Lease may be given by or to any one thereof, and shall have the same force and
effect as if given by or to all thereof.  The words "his" and "him" or "its"
wherever stated herein, shall be deemed to refer to the "Landlord" or "Tenant"
whether such Landlord or Tenant be singular or plural and irrespective of
gender.  No rights, however, shall inure to the benefit of any assignee of
Tenant unless the assignment to such assignee has been approved by Landlord in
writing as aforesaid.

  33.  Security Deposit.  Tenant has deposited with Landlord at the signing of
       ----------------                                                       
this Lease, the sum of Nine Thousand Three Hundred Thirty-One and 98/100 Dollars
($9,331.98) representing three  (3) months' security for the faithful
performance and observance by Tenant of the terms, provisions and conditions of
this Lease.  Tenant shall not be entitled to interest on any such security
deposit.  It is agreed that in the event Tenant defaults in respect of any of
the terms, provisions and conditions of this Lease, including but not limited to
the payment of rent and additional rent, Landlord may use, apply or retain the
whole or any part of the security so deposited to the extent required for the
payment of any rent and additional rent or any other sum as to which Tenant is
in default or for any sum which Landlord may expend or may be required to expend
by reason of Tenant's default in respect of any of the terms, covenants and
conditions of this Lease, including but not limited to any damages or deficiency
accrued before or after summary proceedings or other re-entry by the Landlord.
In the event that Tenant shall fully and faithfully comply with all of the
terms, provisions, covenants and conditions of this Lease, the security shall be
returned to Tenant after the date fixed as the end of the Lease and after
delivery of entire possession of the Demised 

                                       20
<PAGE>
 
Premises to the Landlord.

  In the event of a sale of the land and building or leasing of the building, of
which the Demised Premises form a part, Landlord shall have the right to
transfer the security to the vendee or lessee and Landlord shall thereupon be
released by Tenant from all liability for the return of such security; and it is
agreed that the provisions hereof shall apply to every transfer or assignment
made of the security to a new Landlord.

  Tenant further covenants that it will not assign or encumber or attempt to
assign or encumber the monies deposited herein as security and that neither
Landlord nor its successors or assigns shall be bound by any such agreement,
encumbrance, attempted assignment or attempted encumbrance.

multitenant building with or without common areas, then Tenant shall be liable
for payment of any taxes, charges, premiums, rates, or assessments payable under
the terms of this Lease including, but not limited to those set forth in
Sections 7(b), (c), and (e) herein for the Demised Premises and common areas,
pro-rated based upon the ratio which the total number of leasable square feet of
floor space in the Demised Premises bears to the total number of square feet of
leasable floor space in the entire building as set forth below.

  Tenant's Pro Rata Share: 6.66% (determined by dividing the area of the Demised
Premises [4,666 rentable square feet] by the area of the building of which the
Demised Premises is a part [ 70,000 square feet]).

  36.  Late Payment.  In the event that any payment of Basic Rent or additional
       ------------                                                            
rent or any other charge required to be paid by Tenant under the provisions of
this Lease, shall not be paid within five (5) days of the due date, Tenant shall
pay to Landlord a late charge of five (5%) percent of such past due payment; and
such late charge shall be deemed "rent" for all purposes under this Lease.
 
  37.  Severability.  If a provision of this Lease Agreement is held invalid, it
       ------------                                                             
is hereby agreed that all valid provisions that are severable from the invalid
provision remain in effect.  If a provision in this Lease Agreement is held
invalid in one or more of its applications, the provision remains in effect in
all valid applications.

  38.  Landlord's Liability.  Anything to the contrary herein notwithstanding,
       --------------------                                                   
Landlord's liability for any damages or assessments hereunder shall be limited
solely to Landlord's interest in the Demised Premises or land and building of
which the Demised Premises is part, as the case may be.  It is further
covenanted and agreed by the parties hereto that in no case shall the Landlord
be liable for any consequential damages.

advertise Tenant's occupancy of the Premises and direct visitors, guests and the
like to Tenant's Premises provided that they comply with any and all laws and
ordinances applicable thereto.  Tenant shall not place any sign on any part of

hazardous substances or materials.  Tenant shall not allow the storage or use of
such substances or materials in any manner not sanctioned by law or by the
highest standards prevailing in the industry for the storage and use of such
substances except to use in the ordinary course of Tenant's business, and then
only after written notice is given to Landlord of the identity of such
substances or materials.  Without limitation, hazardous substances and materials
shall include those described in the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, as amended, 42 U.S.C. Section 9601 et
seq., any applicable state or local laws and the regulations adopted under these
acts.  If any lender or governmental agency shall ever require testing to
ascertain whether or not there has been any release of hazardous materials, then
the reasonable costs thereof shall be reimbursed by Tenant to Landlord upon
demand as additional charges if such requirement applies to the Premises.  In
addition, Tenant shall execute affidavits, representations and the like from
time to time at Landlord's request concerning Tenant's best knowledge and belief
regarding the presence of hazardous substances or materials on the Premises.  In
all events, Tenant shall indemnify Landlord in the manner elsewhere provided in
this lease from any release of hazardous materials on the Premises occurring
while Tenant is in possession, or elsewhere if caused by Tenant or persons
acting under Tenant.  The within covenants shall survive the expiration or
earlier termination of the lease term.

  (b)  Tenant shall conduct all of its operations at the Premises in compliance
with all federal, state and local statutes (including, but not limited to the
Comprehensive Environmental Response, Compensation, and Liability Act, 42 U.S.C.
Section 9601 et. seq, as amended by the Superfund Amendments and Reauthorization

hazardous substances or toxic substances as defined therein ("Environmental
Statutes").  Tenant shall obtain all permits, licenses or approvals and shall
make all notifications and registrations required by Environmental Statutes and
shall submit to Landlord, upon request, for inspecting and copying all
documents, permits, licenses, approvals, manifests and records required to be

notice of violation, summons, order, complaint or other document received by
Tenant pertaining to compliance with Environmental Statutes.

for the storage of any liquid or gas above or below ground except as in
compliance with the other provisions of this section and after obtaining written
permission to do so from Landlord.

  (d)  If, because of the manner in which Tenant operates its business, the
Landlord, Landlord's mortgage lender or a governmental agency shall require
testing by an environmental testing entity of its choice, to ascertain whether
there has been a release of Hazardous Materials by Tenant, its agents, servants,
employees or business invitees, in or around the Demised Premises, the
reasonable costs of such testing shall be reimbursed by Tenant to Landlord as
Additional Rent.  Tenant shall execute affidavits or representations, at
Landlord's request, stating that, to the best of Tenant's knowledge and belief,
since the time that Tenant took possession of the Demised Premises, there have
been no and there presently are no Hazardous Materials present in the Demised
Premises.

  (e)  Tenant hereby agrees to indemnify Landlord and to hold Landlord harmless
of, from and against any and all expense, loss, cost, fines, penalties, loss of
value or liability suffered by Landlord by reason of Tenant's breach of any of
the provisions of this section.

  (f)  The provisions of this section shall survive the termination of Tenant's

Premises by substituting comparable space with comparable work in the building
or in the same business park in a similar building.  In such case, Landlord will

last paragraph of Section 4(b)) are at least $3,000,000 for a period of 12

the first such 12-month period only, Employee will be granted by the Company
options to purchase 50,000 shares of the Company's Common Stock at $1.75 per
share pursuant to a separate option agreement.  If at or prior to the end of the

          6.  Termination Provisions.
              ---------------------- 

          (a) Termination for Cause.  The Board may terminate the Employee's
              ---------------------                                         
employment hereunder for Cause, as hereinafter defined, immediately upon written
notice to the Employee.  For purposes of this Agreement, "CAUSE" shall mean (i)
embezzlement, theft or other misappropriation of any property of the Company or
any Affiliate, (ii) gross or willful misconduct resulting in substantial loss to
the Company or any Affiliate or substantial damage to the reputation of the
Company or any Affiliate, (iii) any act involving moral turpitude which results
in a conviction for a felony involving moral turpitude, fraud or
misrepresentation, (iv) gross neglect of his assigned duties to the Company or
any Affiliate, (v) gross breach of his fiduciary obligations to the Company or
any Affiliate, or (vi) any chemical dependence which materially affects the
performance of his duties and responsibilities to the Company or any Affiliate;
provided that in the case of the misconduct set forth in clauses (iv)
- --------                                                             
and (vi) above, such misconduct shall continue for a period of 30 days following
written notice thereof by the Company to the Employee.  During the Term, the
Employee shall be entitled to only one such notice and right to cure for any
single act or event.  If the Employee's employment is terminated for Cause, the
Employee shall be entitled to receive only the unpaid portion of the Salary then
in effect which has accrued to the date of termination and any other payments
generally available to departing employees of the Company (such as unused
vacation and personal days).  The Employee shall not be entitled to receive any
severance payment with respect to such termination.  For the purpose of this
Agreement, the term "AFFILIATE" means, with respect to the Company, any person
or entity which, directly or indirectly, controls, is controlled by or under
common control with the Company, with "CONTROL" to be based on the ownership of
50% or more of the voting securities (or their equivalent) of a particular
entity.

          (b) Termination By Reason of Permanent Disability. If at any time
              ---------------------------------------------
during the Term the Employee has been unable, as a result of physical or mental
illness or incapacity, to perform his duties hereunder for a period of four
consecutive months or for an aggregate of more than six months in any twelve
month period (a "PERMANENT DISABILITY"), the Employee's employment hereunder may
be terminated by the Board upon thirty days' written notice to the Employee. If
the Employee's employment is terminated by reason of Permanent Disability, the
Employee shall be entitled to receive only the unpaid portion of the Salary then
in effect which has accrued to the date of termination, plus any other payments
generally available to departing employees of the Company (such as unused
vacation and personal days), plus an amount equal to three months of Employee's
Salary. Such amount shall be paid within thirty days after such termination.

          (c) Termination By Reason of Death. The Employee's employment
              ------------------------------
hereunder shall automatically terminate on the date of his death. If the
Employee's employment is so terminated by his death, the Company shall pay to
the Employee's estate in addition to the unpaid portion of the Salary then in
effect through date of Employee's death plus an amount equal to three months of
Employee's Salary, plus a pro rata portion of the Bonus which has accrued to the
date of Employee's death if such death occurs within the last six months of a
consecutive 12-month period during the Term, and plus any other payments
generally available to departing employees of the Company (such as unused
vacation and personal days). Such amount shall be paid within thirty days after
the date of his death if a personal representative has been appointed by the end
of such thirty day period or, if a personal representative has not been
appointed by the end of such thirty day period, promptly after a personal
representative has been appointed.

          (d) Termination Without Cause.  The Board may terminate the Employee's
              -------------------------                                         
employment hereunder at any time for any reason without Cause in which case the
Employee shall be entitled to receive an amount (the "SEVERANCE AMOUNT") equal
to six months of Employee's Salary and a pro rata portion of the Bonus which has
accrued to the date of termination if such termination occurs within the last
six months of a consecutive 12-month period during the Term.  The Severance
Amount shall be in lieu of any other severance payment to which Employee may be
otherwise entitled under any other severance plan maintained by the Company.
The Severance Amount shall be paid within 30 days of such termination.  In
addition, the Employee shall be entitled to receive any other payments generally
available to departing employees of the Company (such as unused vacation and
personal days).

     of its subsidiaries or Affiliates;

               (iii) the Employee agrees to take all reasonable steps necessary,

any of its subsidiaries or Affiliates of which the Employee gains or has
acquired knowledge during or prior to the Term by reason of his employment with
the Company that is (A) not generally known in any industry in which the Company

with all written, graphic and other materials relating to all or any part of the
same.

          8.  Improvements and Inventions.
              --------------------------- 

          (a) Disclosure of All Improvements and Inventions.  All designs,
              ---------------------------------------------               
discoveries, ideas and inventions, whether or not patentable, copyrightable or
protectable as trade secrets, and all innovations, improvements, variations,
modifications, and substitutions in each case to the extent relating to the

a light source or relating to "curing" materials used in the treatment of human
teeth, whether or not patentable, copyrightable or protectable as trade secrets,
including all patent and patent application rights and copyright and copyright
application rights relating thereto which the Employee may make or conceive
jointly or commonly with others during the Term in the course of performing his
duties for the Company based, in whole or in part, upon the Confidential
Information, or resulting, in whole or in part, from any other resources,
supplies, facilities or equipment or business, technical or financial

          (b) Assignment of Inventions.
              ------------------------ 

              (i)  In consideration of the compensation payable to the Employee
     under Section 4 hereof, the Employee agrees that all Inventions described
     in paragraph (a) above shall be the sole and exclusive property of the
     Company and available to the Company at all times.  At the request of the
     Company, the Employee agrees to sell, assign, transfer and set over to the
     Company, or its nominee, without royalty or any additional consideration,

     preparation, filing, prosecution and procuring of trademark, copyright
     and/or patent applications and/or trademarks, copyrights and letters patent
     in any country of the world and for the transfer of interests therein,
     including the execution of original, divisional, continuing and reissue

              (iii) The Employee further agrees that if it is legally or
     otherwise impossible for the Company or its designees or assignees to apply
     for any such trademark, copyright or letters patent, or if any court or
     other body with appropriate jurisdiction finds the transfer of trademark,
     copyright or patent rights and/or other rights in any Invention to the
     Company hereunder to be unenforceable for any reason, then, in any such
     case, the Employee in lieu of the Company shall pursue such trademark,
     copyright or letter patent in his own name and shall grant the Company the
     first option to an exclusive license, at a de minimis royalty to be
     negotiated in good faith based on the respective parties' contributions and
     relevant industry standards, to utilize the trademark or copyright or to
     manufacture, utilize and/or sell Inventions which constitute and/or contain
     such patent, trade secret, know-how and/or other proprietary information.
     If such a license is not created, then the Company shall be able to use
     such Invention or substance on a non-exclusive, royalty-free basis.

              (iv)  The Employee agrees to give testimony in any court action or

          Assume the Term begins on June 1, 1998 and the sales of the Products
are as follows for each of the following 6-month periods:

June 1, 1998 - November 30, 1998..  1,000,000
November 30, 1998 - June 1, 1999..  1,500,000

</TABLE>

          1. Bruhin is entitled to 50,000 options on November 30, 1999 because
sales of Products for the 12-month period from November 30, 1998 to November 30,
1999 total $3,250,000.  Even though sales in each 12-month period succeeding
November 30, 1999 exceed $3,000,000, Bruhin is not entitled to another grant of
options on account of the $3,000,000 benchmark.

          2. In addition to the 50,000 options to which Bruhin is entitled on
November 30, 1999, Bruhin is entitled to another 50,000 options on November 30,
2001 because sales of Products for the 12-month period from November 30, 2000 to
November 30, 2001 are at least $10,000,000.  Even though sales for the period
June 1, 2001 through June 1, 2002 are also at least $10,000,000, Bruhin is not
entitled to another grant of options on account of the $10,000,000 benchmark.

          -------------------------                                          
the Commencement Date as defined in Section 1.1 of this Lease.

          -----------

improvements and partitions erected by tenant and restore the Leased Premises to

title shall pass to Landlord under this Lease as by a bill of sale.  All such
alterations, removals and restoration shall be accomplished in a good and

the following: (i) the Landlord has not completed its preparation of the Leases
Premises, (ii) the Landlord is unable to give possession of the Leased Premises
by reason of the holding over or retention of possession of any tenant, tenants
or occupants, or (iii) for any other reason, Landlord shall not be subject to
any liability for failure to give possession, although Tenant shall have the
right to terminate this lease if the Leased Premises are not Substantially
Completed (as hereinafter defined), for any reason other than delays caused by
Tenant, by the ninetieth (90/th/) day after the Commencement Date.  Under such
circumstances the rent reserved and covenanted to be paid herein shall not
commence until the Leased Premises are available for occupancy, and no such
failure to give possession on the Commencement Date shall affect the validity of
this Lease or the obligations of the Tenant hereunder.  In the event that the
Commencement Date is delayed pursuant to this Subsection 2.4, the expiration
Date shall be deemed automatically adjusted so as to cause the Lease Term to
remain the same.  As used in this Lease, the term "Substantial Completion" shall
mean the date on which the earlier of the following three  events shall occur:
(i) the Tenant occupies the Leased Premises or a portion thereof; (ii) the date
on which the Landlord or its agent sufficiently complete the Landlord's Work to
enable the Tenant to use the Leased Premises for the purposes intended; or (iii)
the date on which the Landlord or Landlord's Agents sufficiently complete the
Landlord's Work to enable the Tenant's contractors, if any, to begin or complete
any additional work or a portion thereof not to be performed by the Landlord or
its agents.

Premises are in good and satisfactory condition as of the date on which
possession is so taken.  Upon the Commencement Date Tenant shall, if requested
by Landlord, execute and deliver to Landlord a letter of acceptance of delivery
of the Leased Premises, such letter to be on Landlord's standard from therefor.

     plans, or any other similar of like expenses incurred under the provisions
     of any collective bargaining agreement, or any other cost or expense which
     Landlord pays or incurs to provide benefits for employees so engaged in the
     operation, maintenance and repair of the Building, the charges of any
     independent contractor who, under contract with Landlord or its
     representatives, does any of the work of operating, maintaining or
     repairing of the Building, legal and accounting expenses, including, but
     not limited to, such expenses as relate in seeking or obtaining reductions
     in and refunds of Taxes (as hereinafter defined), amortizable expenses, as
     hereinafter described, or any other expense or charge, whether or not
     hereinbefore mentioned, considered as an expense of owning (except for
     ownership interest expenses for servicing mortgage indebtedness),
     maintaining, operating, or repairing the Building.  If any item of Expense,
     though paid in one year, relates to more than on calendar year, at the
     option of Lessor, such Expense shall be proportionately allocated among
     such related calendar years.  Amortizable Expenses shall include but not
     limited to:  (i) any item of operating expenses or group of similar items
     in excess of $10,000.00 which Landlord, in Landlord's sole discretion,
     determines to be distorting the amount of normal operating expenses in any
     calendar year; (ii) the cost of capital improvements or depreciable
     equipment which reduces some of the operating expenses or are required by
     law or applicable government regulation; or (iii) the unamortized portions

                                       5
<PAGE>
 
     of such expenses, plus interest on any unamortized amount thereof at the
     rate of ten percent (10%) per annum, may be amortized by Landlord over a
     period of not less than five (5) years or more than (10) years.  Expenses
     shall not include depreciation, the cost of altering or finishing other
     tenant space, rent under any ground lease and brokerage and leasing
     commissions.

          (2) "Rent Adjustment" means any amount owed by Tenant resulting from
               ---------------                                                
     increases in expenses and/or Taxes.  The Rent Adjustment shall be paid in
     addition to Base Rent and, notwithstanding anything herein to the contrary,
     shall be determined on a calendar year basis as opposed to a Lease Year.

          (3) "Rentable Area of the Building" is 81,044 square feet.
               -----------------------------                        

          (4) "Rentable Area of the Entire Leases Premises" is defined in
               -------------------------------------------               
     Section 1.1 of the Lease.  The parties acknowledge and agree that the
     Rentable Area of the Entire Leased Premises is computed by multiplying the
     usable square footage of the Leased Premises by a faction of 1.15.

          (5) "Rent Adjustment Deposit" shall be equal to the Rent Adjustments
               -----------------------                                        
     reasonably estimated by Landlord with respect to any calendar year (or any
     portion of a calendar year) included in the term of this Lease, divided by
     the number of months in said calendar year within the term hereof.  The
     Rent Adjustment Deposit shall be subject to change in accordance with
     provisions of Section 3.2(e).

          (6) "Taxes" means real estate taxes, assessments, sewer rents, rates
               -----                                                          
     and charges, transit taxes, taxes based upon the receipt of rent, and any
     other federal, state or local government charges, general, special,
     ordinary or extraordinary (but not including income of franchise taxes or
     any other taxes imposed upon or measured by Landlord's income or profits,
     unless the same shall be imposed in lieu of real estate taxes), which may
     now or hereafter be levied or assessed against the Building or the real
     estate underlying the Building excepting therefrom any interest and/or
     penalties payable on any of the above amounts due as a result of late
     payments.  In case of special taxes or assessments which may be payable in
     installments, only the amount of each installment paid during a calendar
     year shall be included in Taxes for that year.  Taxes shall also include
     any personal property taxes (attributable to the year in which paid)
     imposed upon the furniture, fixtures, machinery, equipment, apparatus,
     systems and appurtenances used in connection with the Building for the
     operation thereof.  The amount of Taxes attributable to any calendar year
     of the term of this Lease shall be the amount of Taxes payable in such
     year, notwithstanding that in each case the assessments for such Taxes may
     have been made for a different year or different years than the year in
     which payable.

          (7) "Tenant's Proportionate Share" is defined in Section 1.1 of the
               ----------------------------                                  
     Lease and means the proportion the Rentable Area of the Leased Premises
     bears to the Rentable Area of the Building.

                                       6
<PAGE>
 
     (b) If the amount of Expenses attributable to any calendar year during the
term hereof is greater than the Expense Base Stop defined in Section 1.1 of the
Lease, then Tenant shall pay Landlord as a Rent Adjustment for such calendar
year, Tenant's Proportionate Share of such excess.

     (c) If the amount of Taxes attributable to any calendar year during the
term hereof is greater than the Expense Base Stop defined in Section 1.1 of the
Lease, then Tenant shall pay Landlord as a Rent Adjustment for such calendar
year, Tenant's Proportionate Share of such excess.

     (d) Tenant shall pay Landlord the Rent Adjustment Deposit in the same
manner as Base Rent, in advance on the first day of each month during the term
hereof, provided however, the first monthly payment shall be made upon execution
hereof.

     (e) As soon as reasonably feasible after the expiration of each calendar
year during the term hereof, Landlord will furnish Tenant a statement (the
"Statement") showing the following:  (1) Expenses and Taxes for said calendar
year; (2) The amount of Rent Adjustment due Landlord for said calendar year ,
less credits for Rent Adjustment Deposits paid and attributable to said calendar
year, if any; and (3) The Rent Adjustment Deposit due in the current calendar
year, and the amount or revised amount due for the months prior to the rendition
of the Statement or any Revised Statement as hereinafter defined.  Any amount
due Landlord as shown on any such Statement shall be paid by Tenant within
thirty (30) days after it is furnished to Tenant.  Any over-payment by Tenant
shall be credited towards the monthly Rent Adjustment Deposits next coming due.
If any increase in Expenses occurs at any time after the preparation of any
Statement which increase results in a projected increase of five (5%) percent or
more in Expenses, the Statement may be revised by Landlord and the Rent
Adjustment Deposits for the remainder of the then current calendar year shall be
revised by entering such increases in expenses into the annualized projection
used in the Statement and recalculating the Rent Adjustment Deposits to provide
for the full payment of the new projected estimate of calendar year Expenses in
the months remaining in said calendar year after the issuance of such a  revised
statement (the "Revised Statement").  If a Revised Statement is issued, the
monthly amount due Landlord for the months prior to the rendition of the next
Statement in the succeeding calendar year shall be equal to one-twelfth (1/12th)
the amount of the recalculated annualized projection.

     (f) If the Commencement Date is on any day other than the first day of
January, or if the termination date is on any day other than the last day of
December, any Rent Adjustment Deposit payment due Landlord shall be prorated,
and Tenant shall pay such amount within thirty (30) days after being billed.
This covenant shall survive the termination of this Lease.

     3.3  Electric Service.  To the extent Tenant is not billed directly by a
          ----------------                                                   
public utility, Tenant shall pay Landlord in advance monthly, upon demand, as
additional rent, Landlord's monthly estimate of all electricity used by Tenant
in the Leased Premises for lighting, convenience outlets, and other direct uses.
Any difference between the Landlord's estimate and the Tenant's actual use as
subsequently determined by Landlord shall either be billed or credited to
Tenant's subsequent rent 

                                       7
<PAGE>
 
bills as the case may require. Tenant's actual use shall be based upon Tenant's
pro-rata share of the total electrical charges of the Building, however,
Landlord may, in its sole discretion, adjust said amount based upon any
extraordinary use of electrical power by Tenant, including, without limitation,
extended hours of operation as compared to other tenants of the Building and the
operation of equipment requiring large amounts of electricity. Tenant shall
furnish, at its own expense, all electric light bulbs, tubes and ballasts during
the Lease Term, provided, however, that Landlord agrees that all lighting
fixtures, light bulbs, tubes and ballasts provided by Landlord shall be in
working condition at the commencement of the Lease Term. Tenant will not without
the written consent of Landlord use any apparatus or device, including but not
limited to any computers and other high technology equipment in the Leased
Premises, which will in any way increase its usage beyond the amount of
electricity which Landlord determines to be reasonable for use of the Leased
Premises for the permitted uses described herein, nor connect with electric
current (except through existing electrical outlets in the Leased Premises).
Tenant shall not use or require electric current in excess of that which is
reasonably obtainable from existing electric outlets and normal for use of the
Leased Premises as determined by the Landlord for the permitted uses described
herein, unless Tenant shall first have procured the consent of Landlord and
Tenant shall have paid all costs of installation of all facilities necessary to
furnishing such excess capacity and for such increased electricity usage.
Interruptions of any service provided by Landlord and Tenant shall have paid all
costs of installation of all facilities necessary to furnishing such excess
capacity and for such increased electricity usage. Interruptions of any service
provided by Landlord resulting in whole or in part from any cause of causes
beyond the reasonable control of Landlord shall not be deemed an eviction or
disturbance of Tenant's use and possession of the Leased Premises or any part
thereof, or render Landlord liable for damages by abatement of rent or otherwise
or relieve Tenant from performance of Tenant's obligations under this Lease.

     3.4  Miscellaneous Charges.  Tenant shall also pay to Landlord as
          ---------------------                                       
additional rent hereunder all other sums payable to Landlord pursuant to any
other provision of this Lease.

     4.   Security Deposit.  In addition Tenant agrees to deposit, as a Security
          ----------------                                                      
Deposit, with Landlord on the date hereof the sum defined in Section 1.1, which
sum shall be held by Landlord, as security for the full, timely and faithful
performance of Tenant's covenants and obligations under this Lease, it being
expressly understood and agreed that such deposit is not an advance rental
deposit or a measure of Landlord's damages in case of Tenant's default.  Unless
specifically required by law, no interest shall be paid on the Security Deposit.
Upon the occurrence of any default by Tenant, Landlord may, from time to time,
without prejudice to any other remedy provided herein or provided by law, use
such fund to the extent necessary to make good any arrears of rent or other
payment due Landlord hereunder, and any other damage, injury, expense or
liability caused by any event of Tenant's default; and Tenant shall pay to
Landlord on demand the amount so applied in order to restore the Security
Deposit to its original amount.  Although the Security Deposit shall be the
property of Landlord, any remaining balance of such deposit shall be returned by
Landlord to Tenant at such time after termination of this Lease when Landlord
shall have determined that Tenant's obligations under this Lease have been
fulfilled.  If the Building is conveyed by Landlord, said deposit may, subject
to the other terms and conditions contained in this Lease, be turned over 

                                       8
<PAGE>
 
to Landlord's grantee, and in such event, Landlord shall be released from any
and all liability to Tenant with respect to said deposit and its application or
return. In the event that the Security Deposit is defined in Section 1.1 as a
specified number of months, then the initial Security Deposit shall be equal to
the product of the number of months specified in Section 1.1 multiplied by the
sum of the monthly Base Rent and the monthly Rent Adjustment Deposits.
Thereafter, Tenant shall maintain the Security Deposit at an amount at all times
equal to the product of the number of the months specified for the Security
Deposit in Section 1.1 multiplied by the sum of the monthly Base Rent and the
Rent Adjustment Deposits. Upon request from time to time, Tenant will
immediately deposit additional sums, if any, required to maintain the Security
Deposit at such amount based on Landlord's estimate of the Rent payable during
the twelve months following any such request.

     5.   Building Services.  Landlord agrees to furnish Tenant, at Landlord's
          -----------------                                                   
expense, while occupying the Leased Premises:  (a) janitor and maintenance
service on a daily basis, excluding weekends and Holidays (as hereinafter
defined); (b) passenger elevator service in common with other tenants daily and
freight elevator service in common with other tenants upon request; (c) water,
at those points of supply provided for general use of tenants; and (d) heated or
cooled air in season at such times as Landlord normally furnishes these services
to all tenants of the Building, and at such temperatures and in such amounts as
are in accordance with any applicable statutes, rules or regulations such
service on Sunday and Holidays to be provided by Landlord at Landlord's sole
option, and upon prior written request from Tenant (Landlord hereby reserves the
right to charge Tenant for any such Sunday or Holiday service used by Tenant on
a prorated basis with those other tenants, if any, using the service during said
time periods).  Holidays shall mean and include only the following days:  New
Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving and
Christmas.  At night, the building shall be locked and access shall be the same
as now exists in the Building.  If heat or air conditioning is furnished at the
request of the Tenant in hours other than normal working hours (Monday through
Friday from 8:00 A.M. to 8:00 P.M. and 8:00 A.M. to 4:00 P.M. on Saturday).
Tenant will pay Landlord charges to supply such services at Landlord's costs;
but neither failure to any extent to furnish, nor any stoppage or interruption
of, these defined services, resulting from any cause beyond Landlord's control,
shall render Landlord liable in any respect for damages to any person, property,
or business, nor be construed as an eviction of Tenant or work an abatement of
rent, nor relieve Tenant from fulfillment of any covenant or agreement hereof.
Tenant shall pay Landlord Tenant's Proportionate Share of the costs of such
services, or if ascertainable, the costs of Tenant's actual use of such
services, in monthly installments fixed by Landlord in addition to the Expenses
described in Section 3.2 of this Lease.  Should any equipment or machinery
furnished by Landlord cease to function properly, Landlord shall use reasonable
and diligent efforts to repair the same promptly.  Whenever heat generating
machines or equipment are used by Tenant in the Leased Premises which affect the
temperature otherwise maintained by the air conditioning equipment, Landlord
reserves the right to install air conditioning units in the Leased Premises (or
for the use of the Leased Premises), and the expense of such purchase,
installation, maintenance, and repair shall be paid by Tenant upon demand as
additional rent or in the alternative, Tenant shall continue to occupy the
Leased Premises without further responsibility of Landlord for additional air
conditioning.  Tenant acknowledges that Landlord does not provide 24-hour
security services in the Building, and hereby waives, on behalf of itself, its
officers, shareholders, partners, 

                                       9
<PAGE>
 
employees, agents and invitees, any and all claims of any nature or kind against
Landlord due to the fact that Landlord does not provide 24-hour security
services in the Building.

     6.   USE OF PREMISES

     6.1  Manner of Use.  Tenant will not occupy or use, nor permit any portion
          -------------                                                        
of Leased Premises to be occupied or used, for any business or purpose other
than that described in Section 1.1 or any other use or purpose which is unlawful
in part or in whole or deemed to be so in any manner, or which increases the
hazard of fire, nor permit anything to be done which will render void or in any
way increase the rate of fire insurance on the Building or its contents, and
Tenant shall immediately case and desist from such use, paying all costs and
expenses resulting therefrom.

     6.2  Compliance with Laws.  Tenant shall at its own cost and expense
          --------------------                                           
promptly obtain any and all licenses and permits necessary for any permitted
use.  Tenant shall comply with all governmental laws, ordinances and regulations
applicable to the permitted use and occupancy of the Leased Premises, and shall
promptly comply with all governmental orders and directors for the correction,
prevention and abatement of any violations or nuisances in or upon, or connected
with, the Leased Premises, all at Tenant's sole expense.  If, as a result of any
change in the governmental laws, ordinances, and regulations, the Leased
Premises must be altered to lawfully accommodate Tenant's use and occupancy,
such alterations shall be made only with the consent of Landlord and in
compliance with the terms of this Lease, but the entire cost shall be borne by
Tenant, provided, that, the necessity of Landlord's consent shall in no way
create any liability against Landlord for failure of Tenant to comply with such
laws, ordinances and regulations.

     6.3  Repairs.  Tenant will maintain the Leased Premises (including all
          -------                                                          
fixtures installed by Tenant and plate glass) is in good repair, reasonable wear
and tear excepted, and in a clean and healthful condition, and comply with all
laws, ordinances, orders, rules, and regulations (state, federal, municipal, and
other agencies or bodies having jurisdiction thereof) with reference to
condition, or occupancy of the Leased Premises.  Any repairs or replacements
shall be made in compliance with the terms of this Lease and with materials and
workmanship of the same character, kind and quality as the original.  Tenant
will not, without the prior written consent of Landlord, paint, install lighting
or decorations, or install any signs, window or door lettering or advertising,
media of any type on or about the Leased Premises.

     6.4  Conduct of Business.  Tenant will conduct its business and control its
          -------------------                                                   
agents, employees and invitees in such a manner as not to create any nuisance,
nor interfere with, annoy, or disturb other tenants or Landlord in the
management of the Building, and shall strictly observe any rules Landlord shall
have prescribed.

     6.5  Damage by Tenant.  Tenant shall pay upon demand ad additional rent the
          ----------------                                                      
full cost of repairing any damage to the Leased Premises, Building or related
facilities resulting from and/or caused in whole or in part by the negligence or
misconduct of Tenant, its gents, servants, employees, 

                                       10
<PAGE>
 
patrons, customers, or any other person entering upon the Property as a result
of Tenant's business activities or resulting from Tenant's default hereunder.

     6.6  Condition Upon Termination.  At termination of this Lease, upon its
          --------------------------                                         
expiration or otherwise, Tenant shall deliver up the Leased Premises with all
improvements located thereon (except as herein provided) in good repair and
condition, reasonable wear and tear excepted, broom clean and free of all
debris.

     7.   Inspections.  Landlord shall have the right to enter the Leased
          -----------                                                    
Premises at any time, for the following purposes:  (i) to ascertain the
condition of the Leased Premises; (ii) to determine whether Tenant is diligently
fulfilling Tenants' responsibilities under this Lease; (iii) to clean and to
make such repairs as may be required or permitted to be made by Landlord under
the terms of this Lease; (iv) to do any other act or thing which Landlord deems
reasonable to preserve the Leased Premises and the Building; or (v) to show the
Leased Premises to prospective purchasers or Mortgagees of the Leased Premises,
Building or Property.  During the six (6) months prior to the end of the term
hereof and at any time Tenant is in default hereunder, Landlord shall have the
right to enter the Leased premises at any time for the purpose of showing the
premises.  Tenant shall give written notice to Landlord at least thirty (30)
days prior to vacating and shall arrange to meet with Landlord for a joint
inspection of the Leased Premises.  In the event of Tenant's failure to give
such notice or arrange such joint inspection, any list of needed restoration or
repairs prepared by Landlord as a result of Landlord's inspection at or after
Tenant's vacating the Leased Premises shall be conclusively deemed correct for
purposes of determining Tenant's responsibility for repairs and restoration.

     8.   ASSIGNMENT AND SUBLETTING

     8.1  Restrictions.  Tenant shall not have the right to assign or pledge
          ------------                                                      
this Lease or to sublet the whole or any part of the Leased Premises, whether
voluntarily or by operation of law, or permit the use or occupancy of the Leased
Premises by anyone other than Tenant, without the prior written consent of
Landlord, which consent shall be in Landlord's sole discretion, and such
restrictions shall be binding upon any assignee or subtenant to which Landlord
has consented.  In the event Tenant desires to sublet the Leased premises, or
any portion thereof, or assign this Lease, Tenant shall give written notice
thereof to Landlord at least ninety (90) days prior to the proposed commencement
date of such subletting or assignment, which notice shall set forth the name of
the proposed subtenant or assignee, the relevant terms of any sublease and
copies of financial reports and other relevant financial information of the
proposed subtenant or assignee.  Landlord shall notify Tenant in writing of its
decision to approve or disapprove of the proposed subletting or assignment or to
exercise its option to recapture the Leased Premises (as provided in Paragraph
8.2 below) within thirty (30) days after Landlord's actual receipt of Tenant's
written notice.  Notwithstanding any assignment or subletting to which consent
is given, Tenant shall at all times remain directly, primarily and fully
responsible and liable from the payment of the rent herein specified and for
compliance with all of its other obligations under the terms, provisions and
covenants of this Lease.  Any approved sublease shall be expressly assigned
subject to the terms and conditions of this Lease, 

                                       11
<PAGE>
 
and Tenant shall pay landlord on the first day of each month during the term of
the sublease, one hundred percent (100%) of the excess of all rent and other
consideration due from the subtenant for such month over that portion of the
Base Rent, Rent Adjustment Deposits and Rent Adjustment due under this Lease for
said month which is allocable to the space sublet. Upon the occurrence of an
Event of default (as hereinafter defined), if the Leased Premises or any part
thereof are then assigned or sublet, Landlord, in addition to any other remedies
herein provided or provided by law, may, at its option, collect directly from
such assignee or subtenant all such rents due and becoming due to Tenant under
such assignment or sublease and apply such rent against any sums due to Landlord
from Tenant hereunder, and no such collection shall be construed to constitute a
novation or release of Tenant from the further performance of Tenant's
obligations hereunder. No assignment, pledge, or subletting shall become
effective until said assignee, pledgee, or subtenant has agreed in writing, on a
form prescribed by Landlord, to be bound by this Lease just as if said assignee,
pledgee, or subtenant were the original tenant.

     Notwithstanding anything to the contrary in this Section 8, if Tenant is a
closely-held corporation nd if during the Term of this Lease, the ownership of
shares of stock which constitute control of Tenant changes by reason of sale,
gift or death, Tenant shall notify Landlord of such change within five (5) days
thereof, and Landlord, at its option, may at any time thereafter terminate this
Lease by giving Tenant written notice of said termination at least sixty (60)
days prior to the date of termination stated in the notice.  The term "control"
as used herein means the power to directly or indirectly direct or cause the
direction of the management or policies of the Tenant.  A change or series of
changes in ownership of stock which would result in direct or indirect change in
ownership by the stockholders or an affiliated group of stockholders of less
than fifty percent (50%) of the outstanding voting stock shall not be considered
a change in control.

     8.2  Recapture.  In addition to, but not in limitation of, Landlord's right
          ---------                                                             
to approve of any subtenant or assignee, Landlord shall have the option, in its
sole discretion, in the event of any proposed subletting or assignment, to
terminate this Lease, or in the case of a proposed subletting of less than the
entire Leased Premises, to recapture the whole or the portion of the Leased
Premises to be sublet as of the date the subletting or assignment is to be
effective.  The option shall be exercised, if at all, by Landlord giving Tenant
written notice thereof within thirty (30) days following Landlord's receipt of
Tenant's written notice as the effective date of the sublease or assignment as
if that date had been originally fixed in this Lease for the expiration of the
term hereof. If Landlord recaptures under this paragraph only a portion of the
Leased Premises, the rent during the unexpired term shall abate proportionately
based on the rent contained in this Lease as of the date immediately prior to
such recapture multiplied by a fraction, the numerator of which is the rentable
area recaptured and the denominator of which is the total rentable area of the
Leased Premises immediately prior to such recapture.  Tenant shall, at Tenant's
own cost and expense, discharge in full any outstanding commission obligation on
the part of Landlord with respect to this Lease, and any commission which may be
due and owing as a result of any proposed assignment or subletting, whether or
not the Leased Premises are recaptured pursuant hereto and rented by Landlord to
the proposed tenant or any other tenant.

     9.   FIRE AND CASUALTY DAMAGE.

     9.1  Termination.  If the Building, improvements, or Leased Premises are
          -----------                                                        
rendered partially or wholly untenantable by fire or other casualty, and if such
damage cannot, in Landlords reasonable estimation, be materially repaired within
ninety (90) days of such damage, then Landlord may, at its sole option,
terminate this Lease as of the date of such fire or casualty.  Landlord shall
exercise its option provided herein by written notice to Tenant within sixty
(60) days of such fire or other casualty.  For purposes hereof, the Building,
improvements of Leased Premises shall be deemed "materially repaired" if they
are in such condition as would not prevent or materially interfere with Tenant's
use of the Leased Premises for the purpose for which it was being used before
such casualty.

     9.2  Restoration.  If this Lease is not terminated pursuant to Paragraph
          -----------                                                        
9.1, then Landlord shall proceed with all due diligence to repair and restore
the Building, improvements or Leased Premises, as the case may be (except that
Landlord may elect not to rebuild if such damage occurs during the last year of
the Term exclusive of any option which is unexercised at the date of such
damage).

     9.3  Effect of Termination.  If this Lease shall be terminated pursuant to
          ---------------------                                                
this Section 9, the term of this Lease shall end on the date of such damage as
if that date had been originally fixed in this Lease for the expiration of the
Term hereof.  If this Lease shall not be terminated by Landlord pursuant to this
Section 9 and if the Leased Premises are untenantable in whole or in part
following such damage, the Rent payable during the period in which the Premises
are untenantable shall be abated in the proportion that the untenantable area of
the Leased Premises bears to the total area of the Leased Premises, for the
period from the date of such damage or destruction to (i) the date the damage or
destruction shall be materially repaired, or (ii) if the Building, but not the
Leased Premises, is so damaged or destroyed, the date on which the Leased
Premises shall be made tenantable; provided, however, should Tenant reoccupy a
portion of the Leased Premises during the period the restoration work is taking
place and prior to the date that the Leased Premises are substantially repaired
or restored, the Rent allocable to such reoccupied portion, based upon (A) the
proportion which the area of the reoccupied portion of the Premises bears to (B)
the total area of the Premises, shall be payable by Tenant from and after the
date of such occupancy.  In the event that Landlord should fail to complete such
repairs and material restoration within one hundred fifty (150) days after the
date of such damage, Tenant may at its option and as its sole remedy terminate
this Lease by delivering written notice to Landlord, whereupon the Lease shall
end on the date of such notice as if the date of such notice were the date
originally fixed in this Lease for the expiration  of the Term hereof, provided,
however, that if construction is delayed because of changes, deletions, or
additions in construction requested by tenant, strikes, lockouts, casualties,
acts of God, war, material or labor shortages, governmental regulation or
control or other causes beyond the reasonable control of Landlord, the period
for restoration, repair or rebuilding shall be extended for the amount of time
Landlord is so delayed.

                                       13
<PAGE>
 
     In no event shall Landlord be required to rebuild, repair or replace any
port of the partitions, fixtures, additions and other improvements which may
have been placed in or about the Leased Premises by Tenant.  Any insurance which
may be carried by Landlord or Tenant against loss or damage to the Building or
Leased Premises shall be for the sole benefit of the party carrying such
insurance and under its sole control.

     9.4  Insurance Proceeds.  Notwithstanding anything herein to the contrary,
          ------------------                                                   
in the event the holder of any indebtedness secured by a mortgage or deed of
trust covering the Leased Premises, Building or Property requires that any
insurance proceeds be applied to such indebtedness, then Landlord shall have the
right to terminate this Lease by delivering written notice of termination to
Tenant within fifteen (15) days after such requirement is made by any such
holder, whereupon the Lease shall end on the date of such damage as if the date
of such damage were the date originally fixed in this Lease for the expiration
of the term hereof.

     9.5  Waiver of Subrogation.  Each of Landlord and Tenant hereby releases
          ---------------------                                              
the other from any and all liability or responsibility to the other or anyone
claiming through or under them by way of subrogation or otherwise for any loss
or damage to property caused by fire or any other perils insured in policies of
insurance covering such property, even if such loss or damage shall have been
caused by the fault or negligence of the other party, or anyone for whom such
party shall be responsible, including any other tenants or occupants of the
remainder of the Building in which the Leased Premises are located, provided,
however, that this release shall be lawful at that time and in any event only
with respect to loss or damage occurring during such times as the releasor's
policies shall contain a clause or endorsement to the effect that any such
release shall not adversely affect or impair said policies or prejudice the
right of the releasor to recover thereunder and then only to the extent of the
insurance proceeds payable under such policies.  Each of Landlord and Tenant
agrees that it will request its insurance carriers to include in its policies
such a clause or endorsement.  If extra cost shall be charged therefor, each
party shall advise the other thereof and of the amount of the extra cost, and
the other party, at its election, may pay the same, but shall not be obligated
to do so.  If such other party fails to pay such extra cost, the release
provisions of this Paragraph shall be inoperative against such other party to
the extent necessary to avoid invalidation of such releasor's insurance.

     9.6  Tenant' Property.  In the event of any damage or destruction to the
          ----------------                                                   
Building or the Leased Premises by an peril covered by the provision of this
Section 9, Tenant shall, upon notice from Landlord, forthwith remove, at its
sole cost and expense, such portion or all of the property belonging to Tenant
or his licenses from such portion or all of the Building or the Leased Premises
as Landlord shall request and Tenant hereby indemnifies and holds Landlord
harmless from any loss, liability, costs and expenses, including attorney's
fees, arising out of any claim of damage or injury as a result of any alleged
failure to properly secure the Leased Premises prior to such removal and/or such
removal.

     10.  Liability.  Landlord shall not be liable for and Tenant will indemnify
          ---------                                                             
and hold Landlord harmless from and against any and all loss, liability, costs
and expenses, including 

                                       14
<PAGE>
 
attorney's fees, arising out of any claim of injury or damage on or about the
Leased Premises and/or Property caused by the negligence or misconduct or breach
of this Lease by Tenant, its employees, subtenants, invitees or by any other
person entering the Leased Premises or the Building or Property under express or
implied invitation of Tenant or arising out of Tenant's use of the Leased
Premises. Landlord shall not be liable to Tenant or Tenant's agents, employees,
invitees or any person entering upon the Property in whole or in part because of
Tenant's use of the Leased premises for any damage to persons or property due to
condition, design, or defect in the Building or its mechanical systems which may
exist or occur, and Tenant assumes all risks of damage to such persons or
property. Landlord shall not be liable or responsible for any loss or damage to
any property or person occasioned by theft, fire, act of God, public enemy,
injunction, riot, strike, insurrection, war, court order, requisition or order
of governmental body or authority, or other matter beyond control of Landlord,
or for any injury or damage or inconvenience, which may arise through repair or
alteration of any part of the Building, or failure to make repairs, or from any
cause whatever except Landlord's willful acts or gross negligence. Tenant shall
procure and maintain throughout the term of this Lease a policy of insurance, in
form and substance satisfactory to Landlord, at a policy of insurance, in form
and substance satisfactory to Landlord, at Tenant's sole cost and expense,
naming Landlord as an additional named insured and insuring against all loss,
damage, claims, demands or actions arising out of or in connection with: (i) the
Leased Premises and the leasehold improvements, trade fixtures, merchandise, if
any, and other personal property located thereon; (ii) the condition of the
Leased Premises, and the leasehold improvements, trade fixtures, merchandise and
other personal property located thereon; (iii) the risk of damage to plate
glass, if any; (iv) all boilers, air conditioning equipment and other pressure
vessels and systems, whether fired or unfired, located in the Leased Premises,
if any; and if said objects and the damage that may be caused by them or result
from them are not covered by extended coverage insurance, then such boiler
insurance shall be in an amount not less than One Million Dollars ($1,000,000);
(v) Tenant's operations in and maintenance and use of the Leased Premises; and
(vi) Tenant's liability assumed under this Lease, the limits of such policy to
be in the amount of not less than $5,000,000 per occurrence in respect of injury
to persons (including death) and in the amount of not less than $1,000,000 per
occurrence in respect of property damage or destruction, including loss of use
thereof. Such policy shall be procured by Tenant from responsible insurance
companies satisfactory to Landlord. A certified copy of such policy, together
with receipt evidencing payment of the premium, shall be delivered to Landlord
prior to the Commencement Date of this Lease. Not less than thirty (30) days
prior to the expiration date of such policy, a certified copy of a renewal
thereof (bearing notations evidencing the payment of the renewal premium) shall
be delivered to Landlord. Such policy shall further provide that not less than
thirty (30) days prior to the expiration date of such policy, a certified copy
of a renewal thereof (bearing notations evidencing the payment of the renewal
premium) shall be delivered to Landlord. Such policy shall further provide that
not less than thirty (30) days written notice shall be given to Landlord before
such policy may be canceled or changed to reduce the insurance coverage provided
thereby and shall name Landlord's mortgagee, if any, as an additional named
insured.

     11.  CONDEMNATION.

                                       15
<PAGE>
 
     11.1 Taking of the Whole.  If any substantial part of the Building,
          -------------------                                           
improvements, or Leased Premises should be taken for any public or quasi-public
use under governmental law, ordinance or regulation, or by right of eminent
domain, or by private purchase in lieu thereof, and the taking would prevent or
materially interfere with the use of the Building or Leased Premises for the
purpose of which they are then being used, this Lease shall automatically
terminate effective when the physical taking shall occur in the same manner as
if the date of such taking were originally fixed in this Lease for the
expiration of the Term hereof.

     11.2 Partial Taking.  If part of the Building, improvements, or Leased
          --------------                                                   
Premises shall be taken for any public or quasi-public use under any
governmental law, ordinance or regulation, or by right of eminent domain, or by
private purchase in lieu thereof, this Lease shall not terminate and the Rent
payable hereunder shall not be reduced.  Landlord shall undertake to restore the
Building, improvements and Leased Premises to a condition suitable for Tenant's
use, as near to the condition thereof immediately prior to such taking as is
reasonably feasible under all circumstances.

     11.3 Condemnation Awards.  In the event of any such taking or private
          -------------------                                             
purchase in lieu thereof, Landlord and Tenant shall each be entitled to receive
and retain such separate awards and/or portion of lump sum awards as may be
allocated to their respective interests in any condemnation proceedings;
provided that Tenant shall not be entitled to receive any award for Tenant's
loss of its leasehold interest, the right to such award being hereby assigned by
Tenant to Landlord.

     12.  Holding Over.  Tenant will, at the termination of this Lease by lapse
          ------------                                                         
of time otherwise, yield up immediate possession to Landlord.  If Tenant retains
possession of the Leased Premises or any part thereof after such termination,
then Landlord may, at its option, serve written notice upon Tenant that such
holding over constitutes any on of (i) renewal of this Lease for one year, and
from year to year thereafter, or (ii) creation of a month to month tenancy, upon
the terms and conditions set forth in this Lease, or (iii) creation of a tenancy
at sufferance, in any case upon the terms and conditions set forth in this
Lease; provided, however that the monthly rental (or daily rental under (iii))
shall, in addition to all other sums which are to be paid by Tenant hereunder,
whether or not as additional rent, be equal to double the Rent (including all
additional rent) being paid monthly to Landlord under this Lease immediately
prior to such termination (prorated in the case of (iii) on the basis of a 360
day year for each day Tenant remains in possession.  If no such notice is
served, then a tenancy at sufferance shall be deemed to be created at the rent
in the preceding sentence.  Tenant shall also pay to Landlord all damages
sustained by Landlord resulting from retention of possession by Tenant,
including the loss of any proposed subsequent tenant for any portion of the
Leased Premises.  The provisions of this Section 12 shall not constitute a
waiver by Landlord of any right of re-entry as herein set forth; nor shall
receipt of any rent or any other act in apparent affirmance of the tenancy
operate as a waiver of the right to terminate this Lease for a breach of any of
the terms, covenants, or obligations herein on Tenant's part to be performed.

     13.  Quiet Enjoyment.  So long as Tenant shall not be in default under this
          ----------------                                                      
Lease, Tenant shall be entitled to peaceful and quiet enjoyment of the Leased
Premises subject to the terms of this Lease.

     14.  Events of Default.  The following events shall be deemed to be "Events
          ------------------                                                    
of Default" by Tenant under this Lease:

     (a) Tenant shall fail to pay when or before due any sum of money becoming
due to be paid to Landlord hereunder, whether such sum be any installment of the
Rent herein reserved, any other amount treated as Additional Rent hereunder, or
any other payment or reimbursement to Landlord required herein, whether or not
treated as additional rent hereunder, and such failure shall continue for period
of five (5) days from the date such payment was due; or

     (b) Tenant shall fail to comply with any other term, provision or covenant
of this Lease other than; (i) by failing to pay when or before due any sum of
money becoming due to be paid to Landlord hereunder or (ii) those provided in
Section 8.1, and shall not cure such failure within twenty (20) days (or
forthwith, if the default involves a hazardous condition) after written notice
thereof to Tenant; or

     (c) Tenant shall fail to observe or perform an of the restrictions or
covenants set forth in Section 8.1; or

     (d) Tenant shall abandon or vacate any substantial portion of the Leased

termination of this Lease, by lapse of time or otherwise, or upon termination of
Tenant's right to possession only; or

     (f) The leasehold interest of Tenant shall be levied upon under execution
or be attached by process of law or Tenant shall fail to contest diligently the
validity of any lien or claimed lien and give sufficient security to Landlord to
insure payment thereof or shall fail to satisfy any judgment rendered thereon
and have the same released, and such default shall continue for ten (10) days
after written notice thereof to Tenant; or

     (g) Tenant or any principal, shareholder, general partner or officer of
Tenant shall become insolvent, admit in writing its inability to pay its debts
generally as they become due, file a petition in bankruptcy or a petition to
take advantage of any insolvency statute, make an assignment for the benefit of
creditors, make a transfer in fraud of creditors, apply for or consent to the
appointment of a receiver of itself or of the whole or any substantial part of
its property, or file a petition or answer seeking reorganization or arrangement
under the federal bankruptcy laws, as now in effect or hereafter amended, or any
other applicable law or statute of the United States or any state thereof, or

     (h) A court of competent jurisdiction shall enter an order, judgment or
decree adjudicating Tenant a bankrupt, or appointing a receiver of Tenant, or of
the whole or any substantial part of its property, without the consent of
Tenant, or approving a petition filed against Tenant seeking reorganization or
arrangement of Tenant under the bankruptcy laws of the United States, as 

                                       17
<PAGE>
 
now in effect or hereafter amended, or any state thereof, and such order,
judgment or decree shall not be vacated or set aside or stayed within thirty
(30) days from the date of entry thereof.

     15.  Remedies. Upon the occurrence of any of such Events of Default
          ---------                                                     
described in Section 14 hereof or elsewhere in this Lease, Landlord shall have
the option to pursue any one or more of the following remedies without any
notice or demand whatsoever:
 
     (a) Landlord may, at its election, terminate this Lease or terminate
Tenant's right to possession only, without terminating the Lease;

     (b) Upon any termination of this Lease, whether by lapse of time or
otherwise, or upon any termination of Tenant's right to possession without
termination of the Lease, Tenant shall surrender possession and vacate the
Leased Premises immediately, and deliver possession thereof to Landlord, and
Tenant hereby grants to Landlord full and free license to enter into and upon
the Leased Premises in such event with or without process of law and to
repossess Landlord of the Leased Premises as of Landlord's former estate and to
expel or remove Tenant property therefrom, without being deemed in any manner
guilty of trespass, eviction or forcible entry or detainer, and without
incurring any liability for any damage resulting therefrom, Tenant hereby
waiving any right to claim damage for such reentry and expulsion, and without
relinquishing Landlord's right to rent or any other right given to Landlord
hereunder or by operation of law;

     (c) Upon any termination of this Lease, whether by lapse of time or
otherwise, Landlord shall be entitled to recover as damages, all unpaid and
delinquent Rent, and other sums due and payable by Tenant on the date of
termination, plus the sum of (i) an amount equal to the then present value of
the Rent and other sums provided herein to be paid by Tenant for the residue of
the state Term hereof, less any sums received by Landlord upon reletting of the
Leased Premises (taking into account the time and expense necessary to obtain a
replacement tenant or tenants, including expenses hereinafter described in
subparagraph (d) relating to recovery of the Leased Premises, preparation for
reletting and for reletting itself), and (ii) the cost of performing any other
covenants which would have otherwise been performed Tenant;

     (d)       (i)   Upon any termination of Tenant's right to possession only
         without termination of the Lease, Landlord may, at Landlord's option,
         enter into the Leased Premises, remove Tenant's signs and other
         evidences of tenancy, and take and hold possession thereof as provided
         in subparagraph (b) above, without such entry and possession terminate
         the lease or releasing Tenant, in whole or in part, from any
         obligation, including Tenant's obligation to pay the Rent, hereunder
         for the full Term. In any case Tenant shall pay forthwith to Landlord,
         if Landlord so elects, a sum equal to the entire amount of the Rent,
         hereunder for the residue of the stated Term hereof plus any other sums
         provided herein to be paid by Tenant for the remainder of the Lease
         Term, less any sums received by Landlord upon reletting of the Leased
         Premises (taking into account the time and expense necessary to obtain
         a replacement tenant or tenants, including expenses described in this
         Subparagraph (d)).

               (ii)  Landlord may, and shall use reasonable efforts to relet the
         Leased Premises or any part thereof for such rent and upon such terms
         as Landlord in its sole discretion shall determine (including the right
         to relet the Leased Premises for a greater or lesser term than that
         remaining under this Lease, the right to relet the Leased Premises as a
         part of a larger area, and the right to change the character or use
         made of the Leased Premises)f and Land shall not be required to observe
         any instructions given by Tenant about such reletting. In any such
         case, Landlord may make repairs, alterations and additions in or to the
         Leased Premises, and redecorate the same to the extent Landlord deems
         desirable, and Tenant shall, upon demand, pay the cost thereof,
         together with Landlord's expenses of reletting including, without
         limitation, any broker's commission incurred by Landlord. If the
         consideration collected by Landlord upon any such reletting plus any
         sums previously collected form Tenant are not sufficient to pay the
         full amount of all Rent and other sums reserved in this Lease for the
         remaining Term hereof, together with the costs of repairs, alterations,
         additions, redecorating and Landlord's expenses of reletting and the
         collection of the rent accruing therefrom (including attorney's fees
         and broker's commission), Tenant shall pay to Landlord the amount of
         such deficiency upon demand and Tenant agrees that Landlord may file
         suit to recover any sums falling due under this section from time to
         time and nothing contained in this Lease shall be deemed to require
         Landlord to postpone suit to the date when the Term would have expired,
         nor limit or preclude recovery by Landlord of any sums or damage to
         which, in addition to the damages particularly provided in this
         Paragraph 15. Landlord may lawfully be entitled by reason of any
         default hereunder on the part of the Tenant;

     (e) Landlord may, at Landlord's option, enter into and upon the Leased
Premises, with or without process of law, if Landlord determines in its sole
discretion that Tenant is not acting within a commercially reasonable time to
maintain, repair or replace anything for which Tenant is responsible hereunder
and correct the same, without being deemed in any manner guilty of trespass,
eviction or forcible entry and detainer and without incurring any liability for
any damage resulting therefrom and Tenant agrees to reimburse Landlord, on
demand, as additional rent, for any expenses which Landlord may incur in so
attempting to effect Tenant's compliance with Tenant's obligations under this
Lease;

     (f) Any and all property which may be removed from the Leased Premises by
Landlord pursuant to the authority of the Lease or of law, to which Tenant is or
may be entitled, may be handled, removed and stored, as the case may be, by or
at the direction of Landlord at the risk, cost and expense of Tenant, and
Landlord shall in no event be responsible for the value, preservation or
safekeeping thereof.  Tenant shall pay to Landlord, upon demand, any and all
expenses incurred in such removal and all storage charges against such property
so long as the same shall be in Landlord's possession or under Landlord's
control.  Any such property of Tenant not retaken by Tenant from storage within
thirty (30) days after removal from the Lease Premises shall, at Landlord's
option, conclusively be presumed to have conveyed by Tenant to Landlord under
this Lease as by a bill of sale without further payment or credit by Landlord to
Tenant.

                                       19
<PAGE>
 
     In the event Tenant fails to pay any installment of Rent or other sums
hereunder as and when such installment or other charge is due, Tenant shall pay
to Landlord on demand a late charge in an amount equal to five (5%) of such
installment or other charge overdue in any month and five percent (5%) each
month thereafter until paid in full to help defray the additional cost to
Landlord for processing such late payments, and such late charge shall be
additional rent hereunder and the failure to pay such late charge within ten
(10) days after demand therefor shall be an additional event of default
hereunder.  The provisions for such late charge shall be in addition to all of
Landlord's other rights and remedies hereunder or at law and shall not be
construed as liquidated damages or as limiting Landlord's remedies in any
manner.

     Pursuit of any of the foregoing remedies shall not preclude pursuit of any
of the other remedies herein provided or any other remedies provided by law (all
such remedies being cumulative), nor shall pursuit of any remedy herein provided
constitute a forfeiture or waiver of any rent due to Landlord hereunder or of
any damages accruing to Landlord by reason of the violation of any of the terms,
provisions and covenants herein contained.  No act or thing done by Landlord or
its agents during the Term hereby granted shall be deemed a termination of this
Lease or an acceptance of the surrender of the Leased Premises, and no agreement
to terminate this Lease or accept a surrender of said premises shall be valid
unless in writing signed by Landlord.  No waiver by Landlord of any violation or
breach of any of the terms, provisions and covenants herein contained shall be
deemed or construed to constitute a waiver of any other violation or breach of
any of the terms, provisions and covenants herein contained.  Landlord's
acceptance of the payment of rental or other payments hereunder after the
occurrence of an event of default shall not be construed as a waiver of such
default, unless Landlord so notifies Tenant in writing.  Forbearance by Landlord
to enforce one or more of the remedies herein provided upon an event of default
shall not be deemed or construed to constitute a waiver of such default or of
Landlord's right to enforce any such remedies with respect to such default or
any subsequent default.  Tenant shall pay all of Landlord's costs, charges and
expenses, including court costs and attorneys' fees, incurred in enforcing
Tenant's obligations under this Lease or incurred by Landlord in any litigation,
negotiation or transactions in which Tenant causes the Landlord, without
Landlord's fault, to become involved or concerned.  As used herein attorneys'
fees shall be and mean the normal hourly rate charged by the attorney's (and
their staff) selected by Landlord multiplied by the actual number of hours spent
by such attorneys on such matters.

     Without limited the foregoing, Tenant hereby: (i) appoints and designates
JCF Real Estate, Inc., 8601 West Bryn Mawr Avenue, Suite No. 114, Chicago,
Illinois 60631, or any party Landlord may from time to time hereinafter
designate, by notice to Tenant, as Tenant's true and lawful agent for service or
process only, and agrees that such service of process upon such party shall
constitute personal service of such process upon Tenant (provided, however,
Landlord does not hereby waive the right to serve Tenant with Process by and
other lawful means); and (ii) to the extent that it may lawfully be waived,
expressly waives the service of any notice under any existing or future law of
the State of Illinois applicable to Landlords and Tenants.

          ----------------

whatsoever upon, or in any manner to bind, the interest of Landlord in the
Leased Premises or to charge the rentals payable hereunder for any claim in
favor of any person dealing with Tenant, including those who may furnish
materials or perform labor for any construction or repairs, and each such claim

Tenant, and in case of the filing of any such lien, Tenant will promptly pay
same.  If any such lien shall remain in force and effect for twenty (20) days
after written notice thereof from Landlord to Tenant, Landlord shall have the
right and privilege of paying and discharging the same or any portion thereof
without inquiry as to the validity thereof, and any amounts so paid, including
attorneys fees, court costs and other expenses and interest, shall be so much
additional rent hereunder due from Tenant to Landlord and shall be paid to
Landlord immediately on rendition of bill therefor.  Notwithstanding the
foregoing, Tenant shall have the right to contest any such lien in good faith

connection therewith, protects the interest of Landlord and Landlord's
mortgagee(s) in the Leased Premises, the Property and the improvements thereon,
and Landlord and any such mortgagee(s) are, by the expiration of said twenty
(20) day period, furnished such

          6.  Termination Provisions.
              ---------------------- 

          (a) Termination for Cause.  The Board may terminate the Employee's
              ---------------------                                         
employment hereunder for Cause, as hereinafter defined, immediately upon written
notice to the Employee.  For purposes of this Agreement, "CAUSE" shall mean (i)
embezzlement, theft or other misappropriation of any property of the Company or
any Affiliate, (ii) gross or willful misconduct resulting in substantial loss to
the Company or any Affiliate or substantial damage to the reputation of the
Company or any Affiliate, (iii) any act involving moral turpitude which results
in a conviction for a felony involving moral turpitude, fraud or
misrepresentation, (iv) gross neglect of his assigned duties to the Company or
any Affiliate, (v) gross breach of his fiduciary obligations to the Company or

- --------                                                                      
above, such misconduct shall continue for a period of 30 days following written
notice thereof by the Company to the Employee. During the Term, the Employee
shall be entitled to only one such notice and right to cure for any single act
or event. If the Employee's employment is terminated for Cause, the Employee
shall be entitled to receive only the unpaid portion of the Salary then in
effect which has accrued to the date of termination and any other payments
generally available to 

                                      -2-
<PAGE>
 
departing employees of the Company (such as unused vacation and personal days).
The Employee shall not be entitled to receive any severance payment with respect
to such termination. For the purpose of this Agreement, the term "AFFILIATE"
means, with respect to the Company, any person or entity which, directly or
indirectly, controls, is controlled by or under common control with the Company,
with "CONTROL" to be based on the ownership of 50% or more of the voting
securities (or their equivalent) of a particular entity.

          (b) Termination By Reason of Permanent Disability.  If at any time
              ---------------------------------------------                 
during the Term the Employee has been unable, as a result of physical or mental
illness or incapacity, to perform his duties hereunder for a period of four
consecutive months or for an aggregate of more than six months in any twelve
month period (a "PERMANENT DISABILITY"), the Employee's employment hereunder may
be terminated by the Board upon thirty days' written notice to the Employee.  If
the Employee's employment is terminated by reason of Permanent Disability, the
Employee shall be entitled to receive only the unpaid portion of the Salary then
in effect which has accrued to the date of termination, plus any other payments
generally available to departing employees of the Company (such as unused
vacation and personal days), plus an amount equal to three months of Employee's
Salary.  Such amount shall be paid within thirty days after such termination.

          (c) Termination By Reason of Death.  The Employee's employment
              ------------------------------                            
hereunder shall automatically terminate on the date of his death.  If the
Employee's employment is so terminated by his death, the Company shall pay to
the Employee's estate in addition to the unpaid portion of the Salary then in
effect through date of Employee's death plus an amount equal to three months of
Employee's Salary, plus any other payments generally available to departing
employees of the Company (such as unused vacation and personal days).  Such
amount shall be paid within thirty days after the date of his death if a
personal representative has been appointed by the end of such thirty day period
or, if a personal representative has not been appointed by the end of such
thirty day period, promptly after a personal representative has been appointed.

          (d) Termination Without Cause.  The Board may terminate the Employee's
              -------------------------                                         
employment hereunder at any time for any reason without Cause in which case the
Employee shall be entitled to receive an amount (the "SEVERANCE AMOUNT") equal
to six months of Employee's Salary. The Severance Amount shall be in lieu of any
other severance payment to which Employee may be otherwise entitled under any
other severance plan maintained by the Company. The Severance Amount shall be
paid within 30 days of such termination. In addition, the Employee shall be
entitled to receive any other payments generally available to departing
employees of the Company (such as unused vacation and personal days).

          any of its subsidiaries or Affiliates;

              (iii) the Employee agrees to take all reasonable steps necessary,

          Information pursuant to this subparagraph (iv), he will not make or

              ------------------------ 

              (i)   In consideration of the compensation payable to the Employee
under Section 4 hereof, the Employee agrees that all Inventions described in
paragraph (a) above shall be the sole and exclusive property of the Company and
available to the Company at all times. At the request of the Company, the
Employee agrees to sell, assign, transfer and set over to the Company, or its
nominee, without royalty or any additional consideration, his entire right,
title and interest in, to and under any and all Inventions.

              (ii)  The Employee agrees to execute, both during and after the

any such trademark, copyright or letters patent, or if any court or other body
with appropriate jurisdiction finds the transfer of trademark, copyright or
patent rights and/or other rights in any Invention to the Company hereunder to
be unenforceable for any reason, then, in any such case, the Employee in lieu of
the Company shall pursue such trademark, copyright or letter patent in his own
name and shall grant the Company the first option to an exclusive license, at a
de minimis royalty to be negotiated in good faith based on the respective
parties' contributions and relevant industry standards, to utilize the trademark
or copyright or to manufacture, utilize and/or sell Inventions which constitute
and/or contain such patent, trade secret, know-how and/or other proprietary
information. If such a license is not created, then the Company shall be able to
use such Invention or substance on a non-exclusive, royalty-free basis.

administrative proceeding with respect to any matters mentioned above.
