                 renovation of space for new tenants, and renovation as a
                 result of casualty from causes against which Landlord carried
                 insurance.  If Tenant fails to pay its share of these
                 expenses, Landlord shall have the remedies provided for the
                 failure to pay rent.

         5.2(b)  PAYMENT OF ADDITIONAL RENT:  Additional rent, together with
                 any tax measured by the amount of the additional rent, will be
                 paid in monthly installments on the first day of each month in
                 an amount reasonably established from time to time by
                 Landlord.  Property costs for period including time outside
                 the Lease Term will be prorated.  Landlord will provide an
                 accounting of actual costs at least annually and any refund
                 due Tenant or payment due Landlord shall be paid within
                 fifteen (15) days from receipt of notice.

         5.2(c)  TENANT'S SHARE:  Tenant's share is the percentage obtained by
                 dividing the number of square feet of leasable area in the
                 Premises by the number of square feet of leasable area in the
                 building or Industrial Park (whichever is applicable).  The
                 tenant's share is initially established as set forth in the
                 Information Schedule.

         5.3     RENT OBLIGATIONS INDEPENDENT, STATEMENT, PRORATION, WHERE
                 PAYABLE, LATE CHARGE:  The rent obligations are independent of
                 any other obligations of Tenant or Landlord and Tenant is not
                 entitled to any abatement or reduction in rent except as
                 expressly provided. Tenant waives the benefit of any statute
                 which would alter this agreement of the parties.  Rent due for
                 any period which is less than one month will be prorated.
                 Rent is payable to Landlord at the address listed in the
                 Information Schedule or such other places the Landlord may
                 designate from time to time in writing.  A five (5%) percent
                 handling fee is due on any rent not paid within ten (10) days
                 of the due date, unless Landlord elects to pursue actions
                 under Paragraph 13.

6.       USE:

         6.1     USE:  Tenant covenants and agrees to use the Premises for no
                 purpose other than those listed in the Information Schedule.

         6.2     COMPLIANCE WITH LAW:  Tenant at its expense will comply
                 promptly with all statutes, ordinances, rules and regulations,
                 orders and requirements (including the recommendations of fire
                 rating organizations, Tenant's and Landlord's underwriters and
                 insurance companies), in effect during the Lease Term
                 regulating the use of the Premises by Tenant.  Tenant will not
                 carry on nor permit any dangerous or offensive activity so as
                 to create damage to the Property, waste, a nuisance or
                 disturbance to other tenants.

         6.3     ENVIRONMENTAL PROTECTIONS:  Tenant acknowledges that there are
                 in effect federal, state and local laws, regulations, and
                 guidelines, and that additional and other laws, regulations,
                 and guidelines may hereinafter be enacted to take effect
                 relating to or affecting the Premises, and concerning the
                 impact on the environment of construction, land use,
                 maintenance and operation of structures, and the conduct of
                 business.  Tenant will not cause or permit to be caused, any
                 act or practice, by negligence, omission, or otherwise, that
                 would adversely affect the environment, or do anything or
                 permit anything to be done that would violate any of said
                 laws, regulations or guidelines.  Tenant agrees to comply with
                 Exhibit "D" ("Control of Dangerous/Hazardous Chemicals and
                 Materials").  Tenant shall indemnify, defend, protect and hold
                 Landlord, its employees, agents, officers and directors,
                 harmless from and against all claims, accidents, suits,
                 proceedings, judgments, losses, costs, damages, liabilities
                 (including, without limitation, sums paid in settlement of
                 claims), deficiencies, fines, penalties, punitive damages or
                 expenses (including, without limitation, reasonable attorneys,
                 experts', and consultants' fees, investigation and laboratory
                 fees, court costs and litigation expenses) resulting from any
                 adverse affect to the environment by Tenant, directly or
                 indirectly resulting from the presence of any



                                     -2-
   5

                 Hazardous Materials in, on, or under the Premises that were
                 introduced to the Premises by Tenant.  All obligations of
                 Tenant under this Article 6.3 shall survive the expiration or
                 earlier termination of the Lease.

         6.4     CONDITION OF PREMISES:  Tenant accepts the Premises in the
                 condition existing as of the date of this Lease, subject only
                 to the completion of Landlord's work.  Tenant accepts the
                 Premises subject to all applicable zoning, municipal, county,
                 state and federal laws, ordinances and regulations governing
                 use of the Premises and to any covenants or restrictions of
                 record, and matters disclosed by any attached exhibits.
                 Tenant acknowledges that Landlord and Landlord's agent have
                 not made any representation or warranty as to the suitability
                 of the Premises for Tenant's business.

7.       MAINTENANCE, REPAIRS AND ALTERATIONS:

         7.1     TENANT'S OBLIGATIONS:  During the Lease Term Tenant shall
                 maintain, replace and keep the Premises, fixtures and
                 equipment in good and clean order, condition and repair,
                 including but not limited to all windows and doors and their
                 fixtures, loading dock equipment (dock levelers, overhead
                 doors, dock shelters, seals and bumpers), pavement under sole
                 use of Tenant, electrical system, lighting (fixtures, bulbs,
                 ballasts, starters, and diffusers), plumbing, heating and
                 cooling system and equipment, floors, sprinkler system,
                 interior wall surfaces, interior partitions, mezzanines and
                 all adjacent site improvements.  Tenant will maintain
                 maintenance contracts satisfactory to Landlord covering the
                 air conditioners and insurance policies covering boilers.
                 Tenant waives the benefits of any statute which would give
                 Tenant the right to make repairs at Landlord's expense or to
                 terminate this Lease because of Landlord's failure to keep the
                 Premises in good order, condition and repair.

                 Tenant agrees to store trash in suitable containers outside
                 the building.  Tenant agrees not to store goods, pallets,
                 drums, or any other materials outside the premises.

                 Tenant shall not place a load upon any floor of the premises
                 exceeding the floor load per square foot area which such floor
                 was designed to carry and which is allowed by law.  Use by
                 Tenant of any mezzanines for storage is at Tenant's sole risk
                 and Tenant agrees to indemnify Landlord from any claims
                 resulting from any such use.

                 In the event Landlord designated specific parking areas within
                 the parking and loading areas, Tenant will cause its
                 employees, agents, and invitees to park only in the designated
                 areas.  No repair or servicing of any motorized vehicle shall
                 be allowed in the Premises or any parking or loading areas,
                 roadways or service areas within the Industrial Park.  No
                 vehicle (including equipment, trailers, and machinery) shall
                 be abandoned or disabled or in a state of non-operation or
                 disrepairship upon the property of the Landlord, and Tenant
                 shall enforce this restriction against Tenant's employees,
                 agents, and invitees.  Should Landlord determine that a
                 violation of this restriction has occurred, Landlord shall
                 have the right to cause the offending vehicle to be removed
                 and all costs of such removal shall be the obligation of the
                 Tenant responsible for such vehicle within ten (10) days of
                 written notice to Tenant.

         7.2     LANDLORD'S OBLIGATIONS:  Landlord will maintain the roof, the
                 structural integrity of the exterior walls, structural
                 supports and foundations of the Building and the paved areas
                 of the Industrial Park (except for pavement under Tenant's
                 sole use), unless covered by the provisions of Paragraph 9.3.
                 Landlord may enter the Premises on reasonable notice to carry
                 out its obligations.  Landlord will not unduly interfere with
                 Tenant's operations.  Landlord is not liable for any
                 reasonable interruption of Tenant's use of the Premises.

                 It is expressly agreed between the parties that the Landlord
                 will not be liable to the Tenant for any damage or injury
                 which may be sustained by the Tenant or those claiming through
                 Tenant as a result of leaks in the roof, foundation or outside
                 walls.  The Landlord will be liable to the Tenant only in the
                 event of the Landlord's willful refusal to repair the roof,
                 foundation and outside walls, or Landlord's gross negligence
                 in making such repairs.

         7.3     RAIL SPUR USE AND COSTS (WHERE APPLICABLE):

                 (a)      If Tenant has sole access to a rail spur servicing
                          the Building or Industrial Park, Tenant, at its sole
                          cost and expense, shall maintain and repair the
                          entire rail spur.  Tenant also agrees to reimburse
                          Landlord as additional rent for all insurance and
                          other operating costs incurred by Landlord regarding
                          the rail spur within ten (10) days after receipt of a
                          statement from Landlord.

                 (b)      If more than one tenant has access to a rail spur or
                          spurs servicing the Building or Industrial Park, the
                          Landlord shall coordinate all maintenance and
                          repairs.  Tenants with access to the rail spur(s)
                          shall reimburse Landlord for the maintenance,
                          repairs, insurance and other operating costs based
                          upon the proportion of the Premises to the total
                          leasable area leased, from time to time, to tenants
                          having access to the rail spur(s).  Tenant shall
                          reimburse Landlord as additional rent for such costs
                          within ten (10) days after receipt of a statement
                          from Landlord.

         7.4     SURRENDER OF PREMISES:  At the end of the term,  or any other
                 termination, Tenant will return the Premises in good, clean
                 condition and operating order, after completion of maintenance
                 and replacement which is Tenant's responsibility.  Damage by
                 ordinary wear and tear is excepted to the extent that it is
                 not part of Tenant's obligation to maintain and replace.  Also
                 excepted is casualty from causes against which Landlord
                 carried insurance.  Extraordinary wear and tear due to
                 Tenant's use of the Premises is the responsibility of Tenant.
                 Damage to the Premises caused by Paragraph 7.5(c) removals
                 will be repaired by Tenant.  Tenant shall notify Landlord in
                 writing (cont) at least 120 days prior to vacating the
                 Premises and shall within 30 days prior to vacating arrange to
                 meet with Landlord for a joint inspection of the Premises
                 shall be deemed correct for the purpose of determining
                 Tenant's responsibility for repairs and restoration of the
                 Premises.

         7.5     ALTERATIONS AND ADDITIONS:

         7.5(a)  CONSENT:  Tenant will not make any alterations or improvements
                 to the Premises, or changes to the exterior of the Premises,
                 or the exterior of the Building without Landlord's prior
                 written consent.  Landlord may condition its consent with any
                 of the following:

                 (i)      Tenant's agreement to remove any alterations or
                          improvements upon termination, and to restore the
                          Premises to the prior condition.
                       
                 (ii)     A lien and completion bond equal to one and one-half
                          times the estimated cost of improvements.
                       
                 (iii)    Insurance necessary to protect both parties while
                          work is in progress.

                 (iv)     Waivers of Liens from all contractors or
                          sub-contractors involved in the alterations or
                          improvements.

         7.5(b)  LIENS:  Claims for labor or materials for, or purporting to be
                 for, labor or materials furnished to Tenant shall be paid by
                 Tenant when due, or secured by bond, so as to immediately
                 discharge any liens filed against the Premises, Building or
                 Industrial Park.  In the event Tenant does not discharge any
                 such liens, Landlord shall have the right, but not the
                 obligation, to discharge such liens.  Any such amount paid or
                 incurred by Landlord shall be immediately due and payable as
                 additional rent by Tenant to Landlord together with interest
                 at the rate indicated in Paragraph 24.10 from the date of
                 payment by Landlord until paid by Tenant.

         7.5(c)  SURRENDER OR REMOVAL OF ALTERATIONS:  Unless removal is
                 required by Landlord, at Landlord's option, all alterations or
                 improvements will become the property of Landlord and will be
                 surrendered with the Premises at the end of the Lease Term or
                 other termination, without payment.  Tenant's machinery and
                 equipment, unless it is fixed to the Premises so that it
                 cannot be removed without material damage, remains the
                 property of Tenant and may be removed by Tenant subject to
                 Paragraph 7.4.

8.       INSURANCE:

         8.1     LIABILITY INSURANCE:  During the Lease Term Tenant will
                 maintain a broad form policy of comprehensive general
                 liability insurance insuring Landlord and Tenant against
                 liability arising out of the use, occupancy or maintenance of
                 the Premises.  The insurance will be for not less than
                 $1,000,000 combined single limit personal injury and property
                 damage.  The limits of the insurance will not limit the
                 liability of Tenant. The policy will contain cross-liability
                 endorsements, if applicable, and will insure Tenant's
                 performance of the indemnity provisions of Paragraph 8.5.  If
                 Tenant fails to maintain the required insurance, Landlord may,
                 but is not obligated to, maintain the insurance at Tenant's
                 expense.  The policy shall expressly provide that it is not
                 subject to invalidation of the Landlord's interest by reason
                 of any act or omission on the part of Tenant.

         8.2(a)  LANDLORD'S INSURANCE:  During the Lease Term Landlord will
                 maintain policies of insurance covering loss or damage to the
                 Building in the amount of the full replacement value,
                 providing protection against all perils included within the
                 classification of fire and extended coverage.  Landlord may
                 elect to provide comprehensive general liability insurance,
                 rent loss, vandalism, malicious mischief, sprinkler leakage,
                 war, automobile, umbrella, flood boiler, air conditioner and
                 all-risk insurance.  The insurance will provide for payment
                 for loss to Landlord or to the holder of a first mortgage or
                 deed of trust on the property.

         8.2(b)  PAYMENT OF PREMIUMS, INSURANCE POLICIES:  Landlord shall pay
                 the premiums for the insurance policies maintained by Landlord
                 under Paragraph 8.2(a) and Tenant shall pay Landlord as
                 Additional Rent Tenant's share of the Premiums as provided in
                 Paragraph 5.2.  If the Lease Term expires before the
                 expiration of the insurance period, Tenant's liability shall
                 be prorated on an annual basis.

         8.2(c)  TENANT'S PERSONAL PROPERTY:  Tenant assumes all risk of loss
                 or damage to Tenant's Property.  Tenant assumes the risk that
                 loss or damage to Tenant's Property, to the Premises or to the
                 Property may result in loss of income, profits or goodwill to
                 the business of Tenant or other persons interested in Tenant's
                 Property.  Tenant releases and holds Landlord harmless from
                 liability for these losses or damage, except arising out of
                 Landlord's gross negligence or willful misconduct.  Tenant's
                 Property includes all goods, equipment, inventory,
                 merchandise, records and other personal property and all
                 fixtures, improvements and betterments placed in or about the
                 Premises, belonging to Tenant or any person connected with, or
                 claiming under or through Tenant.  Tenant agrees to indemnify
                 Landlord and save it harmless from all loss or claims,
                 including reasonable attorneys fees and costs in defending a
                 claim, arising out of loss or damage to Tenant's Property
                 belonging to others.  Landlord means Landlord, its employees
                 and agents.

                 TENANT SHALL PROVIDE INSURANCE TO THE EXTENT OF NOT LESS THAN
                 NINETY PERCENT (90%) OF THE FAIR MARKET VALUE OF TENANT'S
                 PROPERTY AS APPRAISED BY TENANT'S INSURER(S), WITH AN AGREED
                 AMOUNT ENDORSEMENT.  TENANT, AT ITS SOLE COST AND EXPENSE,
                 SHALL OBTAIN THE INSURANCE COVERAGES NECESSARY TO PROVIDE
                 PROTECTION FOR THE RISKS AND OBLIGATIONS TO INDEMNIFY ASSUMED
                 BY TENANT AND SHALL MAINTAIN SUCH INSURANCE FOR THE LEASE
                 TERM.  TENANT AGREES TO NOTIFY EACH INSURANCE CARRIER OF THE
                 TENANT'S ASSUMPTION OF RISK, RELEASE AND INDEMNIFICATION
                 STATED ABOVE.  TENANT ACKNOWLEDGES THAT ITS INSURANCE
                 COVERAGES COULD BE VOIDED OR OTHERWISE ADVERSELY AFFECTED BY
                 THE FOREGOING PARAGRAPH UNLESS THE INSURANCE CARRIER HAS
                 WAIVED ITS RIGHT OF SUBROGATION OR HAS OTHERWISE AGREED TO THE
                 ABOVE ASSUMPTION OF RISK, RELEASE AND HOLD HARMLESS AGREEMENT
                 AND INDEMNIFICATION.

         8.3(a)  TENANT'S INSURANCE POLICIES:  Insurance carried by Tenant will
                 be with responsible carriers acceptable to Landlord and
                 licensed in the State in which the Property is located.  The
                 Tenant will deliver to Landlord certified copies of the
                 policies of insurance or certificates evidencing the existence
                 and amounts of the insurance.  No policy shall be cancelable
                 or subject to reduction of coverage or other modification
                 except after 30 days prior written notice to Landlord.  Tenant
                 shall, at least 30 days prior to the expiration of the
                 policies,





                                     -5-
   8

                 furnish Landlord with renewals or "Binders" for the policies,
                 or Landlord may order the required insurance and charge the
                 cost to Tenant pursuant to Paragraph 23.

         8.3(b)  INCREASED RISK:  Tenant will not do anything or permit
                 anything to be done or any hazardous condition to exist
                 ("Increased Risk") which shall invalidate or cause the
                 cancellation of the insurance policies carried by either
                 Tenant or Landlord.  If Tenant does or permits any Increased
                 Risk which causes an increase in the cost of Landlord's
                 insurance policies then Tenant shall reimburse Landlord
                 pursuant to Paragraph 23 for additional premiums attributable
                 to any act, omission or operation of Tenant causing the
                 increase in the premiums, including, but not limited to,
                 non-compliance with recommendations under Paragraph 6.2.
                 Payment of additional premiums will not excuse Tenant from
                 terminating or removing the Increased Risk unless Landlord
                 agrees in writing.  Absent agreement, Tenant shall promptly
                 terminate or remove the Increased Risk.

         8.4     WAIVER OF SUBROGATION ON PROPERTY POLICIES:  Each party
                 releases the other party from any and all liability or
                 responsibility (to the other party or anyone claiming
                 through___ under them by way of subrogation or otherwise) for
                 _____ or damage to property resulting from causes insured
                 against, even if such casualty has been caused by the fault or
                 negligence of the other party, or anyone for whom such party
                 may be responsible.

         8.5     INDEMNIFY:  Tenant shall indemnify and hold harmless Landlord,
                 its agents and employees, from and against any and all claims
                 arising from:  (a) Tenant's use of the Premises, (b) the
                 conduct of Tenant's business or anything else done or
                 permitted by Tenant to be done in or about the Premises or
                 elsewhere in the Industrial Park, (c) any breach or default in
                 the performance of Tenant's obligations under the Lease, or
                 arising from any negligence of the Tenant, or Tenant's agents,
                 contractors or employees.  Tenant shall defend Landlord
                 against all costs, attorney's fees, expenses and liabilities
                 incurred in the defense of any such claim action or
                 proceeding.  In case any action or proceeding is brought
                 against Landlord by reason of a claim, Tenant, upon notice
                 from Landlord, shall defend the same at Tenant's expense by
                 counsel satisfactory to Landlord.  Tenant assumes all risk of
                 damage to property or injury to persons, in or about the
                 Premises arising from any cause and Tenant waives all such
                 claims against Landlord, except claims due to Landlord's gross
                 negligence or willful misconduct.  The liability of Tenant to
                 indemnify Landlord, its agents and employees, shall not extend
                 to any matter against which Landlord shall be effectively
                 protected by insurance, provided that if any liability shall
                 exceed the amount of effective and collectable insurance, the
                 liability of Tenant shall apply to the excess.  Whether the
                 insurance is "effective" depends in part, but not by way of
                 limitation, on the absence of any defense to coverage made the
                 insurer.

9.       CASUALTY, DAMAGE:

         9.1     DAMAGE TO PREMISES:  Tenant will give immediate notice to
                 Landlord of fire or other casualty damage to the Premises.
                 Landlord will repair the Premises, except damage from items in
                 which Tenant is responsible for under Paragraph 6.3 herein and
                 unless it decides to terminate under Paragraph 9.2.  Tenant
                 will be obligated to pay pro rata fixed and additional rent on
                 the portion of the Premises it can occupy.

         9.2     OPTIONS TO TERMINATE:

         9.2(a)  PREMISES DAMAGE:  If the Building is substantially destroyed
                 or the damage requires more than 150 days from the date of the
                 damage to repair, either Landlord or Tenant has the option to
                 terminate this Lease by giving written notice within 30 days
                 after the date of the damage (except Tenant shall not have
                 such option if less than twenty-five (25%) percent of the
                 Premises is damaged, in which case the provisions of 9.2(b)
                 shall apply).  This Lease shall terminate either 30 days after
                 receipt of the notice or the date Tenant vacates the Premises,
                 whichever is sooner.

         9.2(b)  REPAIRS REQUIRING LESS THAN 150 DAYS TO REPAIR:  If the
                 estimated repair time is less than 150 days and Landlord
                 diligently pursues repairs, Tenant may not terminate if repair
                 time runs over 150 days due to causes beyond Landlord's
                 control.





                                     -6-
   9

         9.2(c)  DAMAGE DURING LAST SIX MONTHS OF TERM:  If casualty damage
                 occurs to the Premises or to the Building during the last six
                 (6) months of the Lease Term, Landlord may terminate this
                 Lease.  If Tenant has an unexpired option to extend, the
                 option to extend or renew must be exercised within twenty (20)
                 days of the casualty.  If the option is exercised Landlord may
                 not cancel unless there is substantial damage.  If the option
                 is not exercised, the option is terminated and Landlord may
                 terminate the Lease.

         9.3     NEGLIGENCE OF TENANT - UNINSURED LOSS:  An "Insured Loss" is
                 damage caused by an event which is either required to be or
                 which has been elected by Landlord to be covered by insurance
                 described in Paragraph 8.2(a).  If casualty damage occurs
                 which is not an Insured Loss and which is due to a negligent
                 or willful act of Tenant, Tenant will repair the damage at its
                 expense and will remain liable for the full rent during
                 repair.  Termination under Paragraph 9.2 will not be available
                 to Tenant.

         9.4     TENANT CLAIMS:  No compensation, claims, or diminution of rent
                 will be paid or allowed by Landlord, by reason of
                 inconvenience, annoyance, or injury to business, arising from
                 the necessity of repairing any other portion of the Building
                 however the necessity may occur.

10.      REAL PROPERTY TAXES:

         10.1    PAYMENT OF TAXES:  Landlord shall pay the "Base Real Property
                 Taxes" on the Property during the Lease Term.  Base Real
                 Property Taxes are real property taxes applicable to the
                 Property as shown on the tax bill for the most recent tax
                 fiscal year ending prior to the Commencement Date.  Tenant
                 shall pay Landlord, Tenant's Share of the amount, if any, by
                 which the real property taxes during the Lease Term exceed the
                 Base Real Property Taxes as Additional Rent as provided in
                 Paragraph 5.2.  If the Premises are not separately assessed,
                 Tenant's share of the real property tax payable by Tenant
                 shall be prorated.

         10.2    DEFINITION OF "REAL PROPERTY TAX".  The term "Real Property
                 Tax" includes any form of assessment, license fee, levy,
                 penalty or tax (other than inheritance or estate taxes),
                 imposed by an authority with direct or indirect power to tax
                 any legal or equitable interest of Landlord in the real
                 property of which the Premises are a part, but shall not
                 include any rent tax payable by Tenant under Paragraph 5, nor
                 any corporate franchise or income taxes.

         10.3    PERSONAL PROPERTY TAXES:  Tenant will pay, before delinquent,
                 all taxes assessed against trade fixtures, furnishings,
                 equipment and all other personal property of Tenant.  Tenant
                 will cause these items to be assessed and billed separately
                 from the real property of Landlord.

11.      UTILITIES:  Tenant will pay directly to the appropriate supplier, the
         cost of all water/sewer, gas, heat, light, electrical, telephone,
         refuse disposal and other utilities and services supplied to the
         Premises, and any taxes on those bills.  If any services are not
         separately metered, Tenant will pay as Additional Rent as provided in
         Paragraph 5.2 a proportion of all jointly-metered utilities used by
         other occupants of the property based either upon type and extent of
         use or on area, as reasonably determined by Landlord.

12.      ASSIGNMENT AND SUBLETTING:

         12.1    LANDLORD'S CONSENT REQUIRED:  Tenant will not voluntarily or
                 by operation of law assign, transfer, mortgage, sublet or
                 otherwise transfer or encumber all or part of Tenant's
                 interest in this Lease or in the Premises, without Landlord's
                 prior written consent which consent may not be unreasonably
                 withheld by Landlord.  Any attempted assignment, transfer,
                 mortgage, encumbrance or subletting without consent shall be
                 void as against Landlord, and shall constitute a breach of the
                 Lease.

         12.2    NO RELEASE OF TENANT:  Regardless of Landlord's consent, no
                 subletting or assignment will alter the primary liability of
                 Tenant to pay the rent and to perform all other obligations to
                 be performed by Tenant.  Acceptance





                                     -7-
   10

                 of rent from any other person will not be deemed a waiver by
                 Landlord of any provision of this Lease.  Consent to one
                 assignment or subletting will not be deemed consent to any
                 subsequent assignment or subletting.

         12.3    PARTICIPATION BY LANDLORD:  In the event of any assignment or
                 sublease involving rent in excess of the Fixed Minimum Rent or
                 Additional Rent required under this Lease as Excess Rent),
                 Landlord shall participate in the Excess Rent.  Tenant shall
                 promptly forward to Landlord fifty (50%) percent of all such
                 Excess Rent collected from the assignee or subtenant and shall
                 supply Landlord with true copies as executed of all
                 assignments and subleases.

         12.4    PROCESSING FEES:  If Landlord consents to sublease or
                 assignment, Tenant will pay a processing fee of $350.

13.      DEFAULTS, REMEDIES:

         13.1    EVENTS OF DEFAULT:  It is a default under this Lease if any of
                 the following "Events of Default" happens:

                 (a)      If any Fixed Monthly Rent is not paid when due and
                          default continues for a period of five (5) days; or

                 (b)      If any additional rent is not paid when due and
                          default continues for a period of ten (10) days; or

     (c)      If the provisions of Paragraph 6.3 are not fully complied with; or

                 (d)      If Tenant defaults under any of the terms of this
                          Lease other than those in 13.1(a), (b) and (c), and
                          default continues for fifteen (15) days after written
                          notice (except if default cannot be completely cured
                          within fifteen (15) days, it will not be an Event of
                          Default if Tenant starts to cure within the fifteen
                          (15) day period, and in good faith continually
                          proceeds to remedy the default); or

                 (e)      If Tenant or any person who has guaranteed
                          performance, files a voluntary petition in bankruptcy
                          or is adjudicated a bankrupt or insolvent, or files a
                          petition or answer seeking relief under any federal,
                          state or other statute or regulation, or seeks or
                          consents or acquiesces in the appointment of a
                          trustee, receiver or liquidator of Tenant or
                          guarantor, or of all or any substantial part of
                          Tenant's properties or of the Premises or any or all
                          rents, earnings, or income or makes an assignment for
                          the benefit of creditors, or admits in writing its
                          inability to pay its debts generally as they become
                          due; or

                 (f)      If a petition is filed against Tenant, or any person
                          who has guaranteed performance, seeking relief under
                          any federal, state or other statute or regulation,
                          which remains undismissed or unstayed for an
                          aggregate of sixty (60) days (whether or not
                          consecutive), or if a trustee, receiver or liquidator
                          of Tenant or guarantor, or of all or any substantial
                          part of its properties or of the Premises or any or
                          all rents, or income is appointed without the consent
                          or acquiescence of Tenant, or guarantor, and the
                          appointment remains unvacated or unstayed for an
                          aggregate of sixty (60) days (whether or not
                          consecutive).

                 (g)      In the event Tenant or Tenant's subsidiary or
                          affiliate shall lease other Premises from Landlord,
                          any default under such other leases shall be deemed
                          to be a default under this Lease and Landlord may
                          enforce all rights and remedies for an Event of
                          Default herein.

         13.2    NOTICE, TERMINATION:

                 Landlord at any time after the happening of an Event of
                 Default may declare an Event of Default by written notice to
                 Tenant specifying the Event(s) of Default.  In the same or a
                 later written notice Landlord may elect that this Lease
                 terminate at 5:00 p.m. on the date listed by Landlord.  The
                 date will be at least five (5) days after the giving of the
                 termination notice (including the termination date).  On the
                 date in the notice, subject





                                     -8-
   11

                 to Paragraph 13.4, the Lease and all interests demised will
                 terminate and all rights of the Tenant shall cease.  The
                 termination will not take place if before the stated date and
                 time:

                 (i)      Tenant has paid all arrears of fixed minimum rent and
                          additional rent and all other amounts payable by
                          Tenant (together with interest pursuant to Paragraph
                          24.10) and as additional rent all expenses
                          (including, without limitation, attorney's fees and
                          expenses) incurred by Landlord due to any default by
                          Tenant, (the "arrearages"), and

                 (ii)     All other defaults have been cured to the
                          satisfaction of Landlord.

         13.3    REPOSSESSION, RELETTING:  After notice of an Event of Default,
                 whether before or after a termination as provided in Paragraph
                 13.2, Landlord, without further notice and with no liability
                 to Tenant, may repossess the Premises, by summary proceedings,
                 ejectment or otherwise, and remove Tenant and all other
                 persons and any and all property from the Premises.  After
                 such repossession, Landlord may (but is under no obligation
                 to) relet the Premises, any part thereof, or the Premises with
                 additional premises, on account of Tenant (until Landlord
                 makes demand for final damages), in Tenant's or Landlord's
                 name, without notice to Tenant, for a term (which may be more
                 or less than the period which would have been the balance of
                 the term of this Lease) and on conditions (including
                 concessions, periods of rent free use, or alterations) and for
                 purposes which Landlord determines and Landlord may receive
                 the rents.  landlord is not liable for failure to collect any
                 rent due upon any such reletting.

         13.4    SURVIVAL OF TENANT'S OBLIGATIONS, DAMAGES:  No provisions in
                 Paragraphs 13.1, 13.2 and 13.3, will relieve Tenant of its
                 liability and obligations under this Lease, all of which will
                 survive.  Landlord will not be deemed to accept a surrender of
                 Tenant's lease or otherwise discharge Tenant because Landlord
                 takes or accepts possession of the Premises or exercises
                 control over them as provided.  Acceptance of surrender and
                 discharge may be done only by an instrument executed on behalf
                 of Landlord by its duly authorized officer or employee.

                 In the event of termination or repossession following an Event
                 of Default, Tenant will pay to Landlord the Arrearages up to
                 the earlier of the date of termination or repossession.
                 Further, Tenant until the end of what would have been the term
                 of this Lease in the absence of termination and whether or not
                 the Premises or any part have been relet, is liable to
                 Landlord for, and will pay to Landlord, as liquidated and
                 agreed "Current Damages" for Tenant's default:

                 (a)      The Fixed Minimum Rent and all additional rent and
                          other charges payable by Tenant or which would be
                          payable if this Lease had not terminated, plus all
                          Landlord's expenses in connection with any reletting,
                          including, without limitation, repossession costs,
                          brokerage commissions, legal expenses, attorney's
                          fees, expenses of employees, alteration costs, and
                          expenses of preparation for such reletting.

                 (b)      The net proceeds, if any, of any reletting on account
                          of Tenant pursuant to Paragraph 13.3.  If the
                          Premises have been relet with additional premises,
                          the net proceeds, if any, of reletting shall be
                          prorated.

                 Tenant shall pay Current Damages to Landlord monthly on the
                 days on which the Fixed Minimum Rent would have been payable
                 if the Lease were not terminated, and Landlord is entitled to
                 recover from Tenant each month.  After termination under
                 Paragraph 3.2, whether or not Landlord has collected Current
                 Damages, Tenant will pay to Landlord on demand, as liquidated
                 and agreed "Final Damages" for Tenant's default and in lieu of
                 all Current Damages beyond the date of demand, an amount equal
                 to the present cash value on the date of demand on the Fixed
                 Minimum Rent and additional rent and other charges which would
                 have been payable from the date of demand for what would have
                 been the unexpired term of this Lease if it has not been
                 terminated plus the Arrearages to the earlier of the date of
                 termination or repossession and Current Damages up to the date
                 of demand which remain unpaid.

                 If any statute or rule of law governing a proceeding in which 
                 Final Damages are to be proved validly limits the amount to 
                 an amount less than that provided for, Landlord is entitled to 
                 the maximum amount allowable under the statute or rule of law.
                 The discount rate of interest shall be as provided in 
                 Paragraph 24.10.

14.      CONDEMNATION:

         14.1    PERMANENT CONDEMNATION:  If the Premises or any portion are
                 taken under the power of eminent domain, or sold under the
                 threat of the exercise of the power (both called
                 "Condemnation"), this Lease will terminate as to the part
                 taken as of the first date the condemning authority takes
                 either title or possession.  If the portion of the Premises
                 taken is more than twenty-five (25%) percent or makes the
                 balance unfit for Tenant's use, Tenant has the option to
                 terminate this Lease as of the date the condemning authority
                 takes possession.  The option will be exercised in writing as
                 follows:

                 (i)      Within thirty (30) days after the condemning
                          authority has taken possession.

                 (ii)     Absent notice, within ten (10) days after the
                          condemning authority has taken possession.

                 If Tenant does not terminate, this Lease will remain in full
                 force and effect as to the portion of the Premises remaining.
                 The rent will be proportionately reduced.

                 Any award for Condemnation is the Landlord's whether the award
                 is made as compensation for diminution in value of the
                 leasehold or for the taking of the fee, or as severance
                 damages.  Tenant is entitled to any award for damage to
                 Tenant's trade fixtures and removable personal property and
                 moving expenses.  If this Lease is not terminated, Landlord,
                 to the extent of severance damages received, will repair
                 damage to the Premises caused by Condemnation except to the
                 extent that Tenant has been reimbursed by the condemning
                 authority.  Tenant will pay any amount in excess of the
                 severance damages required to complete the repair.

         14.2    TEMPORARY CONDEMNATION:  Upon Condemnation of all or a part of
                 the Premises for temporary use, this Lease will continue
                 without change or abatement in Tenant's obligations, as
                 between Landlord and Tenant.  Tenant is entitled to the award
                 made for the use.  If the Condemnation extends beyond the term
                 of the Lease, the award will be prorated between the Landlord
                 and the Tenant as of the expiration date of the term.  The
                 Tenant is responsible for the cost of any restoration work
                 required to place the Premises in the condition they were in
                 prior to Condemnation unless the release of the Premises
                 occurs after termination.  In such case, Tenant will assign to
                 the Landlord any claim it may have against the condemning
                 authority.  If Tenant has received restoration funds, it will
                 give the funds to Landlord within fifteen (15) days after
                 demand.

15.      FORCE MAJEURE:  If Landlord's performance of any obligations under any
         provision in this Lease is delayed by an act or neglect of Tenant, Act
         of God, strike, labor dispute, unavailability of materials, boycott,
         governmental restrictions, riots, insurrection, war, catastrophe, or
         act of the public enemy, the period for the beginning or completion of
         the (cont.) obligation is extended for a period equal to the delay.

16.      SUBORDINATION:  This Lease, at Landlord's option, will be subordinate
         to any form of security now or later placed on the property and to all
         advances made on the security and to all renewals, modifications,
         consolidations, replacements and extensions.  Tenant's right to quiet
         possession of the Premises will not be disturbed if Tenant is not in
         default under this Lease, unless it is otherwise terminated under the
         terms.  If any mortgagee, trustee or ground lessor elects to have this
         Lease prior to the lien of its security, and gives written notice to
         Tenant, the Lease will be deemed prior to the security, whether dated
         before or after the date of the security, or the recording date.
         Tenant agrees to execute any required documents, and Tenant
         irrevocably appoints Landlord as Tenant's attorney-in-fact to do so,
         if Tenant fails to so execute within ten (10) days after written
         demand.

17.      ESTOPPEL CERTIFICATE:  Tenant, after not less than ten (10) days prior
         written notice from Landlord, will deliver to Landlord a written
         statement (i) certifying that this Lease is unmodified and in full
         force and effect (or, if modified, stating the nature of the
         modification and certifying that this Lease, as so modified, is in
         full force and effect) and the


                                     -10-
   13

         date to which the rent and other charges are paid in advance, if any,
         (ii) stating the amount of the security deposit, if any, held by
         Landlord and (iii) acknowledge that there are not, to Tenant's
         knowledge, any uncured defaults on the part of Landlord, or stating
         any claimed defaults.  The statement may be relied upon by any
         prospective purchaser or lender of the Premises.

         Tenant's failure to deliver the statement within said time will be
         conclusive upon Tenant (i) that this Lease is in full force and
         effect, without modification except as may be represented by Landlord,
         (ii) that any security deposit is as represented by Landlord, (iii)
         that there are no uncured defaults in Landlord's performance, and (iv)
         that not more than one month's rent has been paid in advance.

         If Landlord desires to sell or finance or refinance all or part of the
         Premises, Tenant agrees to deliver to any proposed purchaser or lender
         named by Landlord all financial statements of Tenant as may be
         reasonably required by the proposed purchaser or lender.  The
         statements will include the past three years' financial statements of
         Tenant.  All financial statements will be received by Landlord in
         confidence and will be used only for these purposes.

18.      CORPORATE AUTHORITY:  If Tenant is a corporation, each individual
         executing this Lease on behalf of the corporation represents and
         warrants that he is duly authorized to execute and deliver this Lease
         on behalf of the corporation, in accordance with a duly adopted
         resolution of the Board of Directors of the corporation, or in
         accordance with the bylaws of the corporation, and that this Lease is
         binding upon the corporation.

19.      NOTICES:  All notices required or permitted under this Lease shall be
         in writing and shall be deemed duly given if sent by United States
         certified or registered mail, return receipt requested, or by Federal
         Express or other major overnight courier that provides evidence of
         delivery, addressed to Landlord or Tenant, respectively, at the
         addresses provided in the Information Schedule.

         Either party by notice as provided above may change the address for
         notices and/or payment of rent.

20.      BROKER'S FEE:  Landlord and Tenant represent and warrant to each other
         that except as listed in the Information Schedule, no broker, agent or
         finder has been employed by or in connection with this Lease and no
         commissions are payable by it to any person.  Tenant and Landlord each
         agree to indemnify, defend and save harmless the other from any
         expenses of claim for fees or commissions resulting from the
         indemnifying party having dealt with any broker, agent or finder in
         negotiating this Lease.  Landlord and Tenant acknowledge that the
         broker(s) in this transaction are as listed in the Information
         Schedule and that payments of commissions will be in accordance with
         their respective agreements.  Tenant represents it did not deal with
         any other broker, agent or finder purporting to represent Landlord.

21.      LANDLORD'S ACCESS:  Landlord and Landlord's agents have the right to
         enter the Premises at reasonable times for the purpose of inspecting,
         showing the Premises to prospective purchasers, tenants, lenders, and
         making alterations, repairs, improvements or additions to the Premises
         or to the Building that Landlord deems necessary or desirable.
         Landlord may place any ordinary "For Sale" or "For Lease" signs on the
         Premises or the Building, without rebate of rent liability.

22.      LANDLORD'S LIABILITY:  The term "Landlord" means only the owner or
         owners of the fee title at the time in question.  If the Landlord (or
         the then grantor) transfers any title or interest, from and after the
         date of transfer the Landlord (or the then grantor) is relieved of all
         liability for Landlord's obligations.  Any Security Deposit not
         delivered to the grantee is excepted.  Landlord's obligations under
         this Lease shall thereafter be binding on Landlord's successors and
         assigns.  Tenant agrees to attorn to any transferee or lender of
         Landlord.

23.      LANDLORD'S RIGHT:  If Tenant fails to make any required payment or
         defaults in performing any other term in this Lease, Landlord may, but
         need not (and without waiving the default), make such payment or
         remedy other defaults for Tenant's account and at Tenant's expense,
         immediately and without notice in case of emergency, otherwise on five
         (5) days written notice to Tenant.  The costs, with interest under
         Article 24.10, and with a charge equaling fifteen (15%) percent of the
         cost (to cover Landlord's overhead), in due as additional rent with
         Tenant's next fixed minimum rent installment.

24.      MISCELLANEOUS:

         24.1    TIME OF ESSENCE:  Time is of the essence under this Lease.

         24.2    COVENANTS AND CONDITIONS:  Each provision of this Lease
                 performable by Tenant is both a covenant and a condition.

         24.3    CAPTIONS:  Article and paragraph captions are only for
                 convenience.

         24.4    INCORPORATION OF PRIOR AGREEMENTS, AMENDMENTS:  This Lease
                 contains all agreements of the parties with respect to any
                 matter mentioned.  No prior agreement or understanding is
                 effective after execution of this Lease.  This Lease may be
                 modified in writing only, signed by the parties.  The Exhibits
                 listed on the Information Schedule and attached to this Lease
                 are part of this Lease as fully as if placed in the body of
                 the Lease.

         24.5    CUMULATIVE REMEDIES:  No remedy or election is exclusive but,
                 wherever possible, is cumulative with all other remedies of
                 law or in equity.

         24.6    SEVERABILITY:  The invalidity of any provision of this Lease
                 as determined by a court of competent jurisdiction, shall not
                 affect the validity of any other provision.  The valid
                 portions of the Lease shall be interpreted together to
                 accomplish the intent of the parties.

         24.7    MERGER:  The voluntary or other surrender by Tenant or a
                 mutual cancellation will work a merger, and at Landlord's
                 option, will terminate existing subtenancies or operate as an
                 assignment of subtenancies.

         24.8    HOLDING OVER:  If Tenant retains possession after the Lease
                 Term expires, without the written consent of Landlord, the
                 occupancy will be a tenancy from month to month at a rent in
                 the amount of twice the last fixed minimum rent plus all
                 additional rent and other charges payable, and upon all other
                 terms contained herein.  Any options (i.e. renewal, expansion)
                 and rights of first refusal contained in the Lease are
                 terminated in the event of a holdover tenancy.

         24.9    WAIVERS:  Waiver by Landlord of any provision is not a waiver
                 of any other provision or of any subsequent breach by Tenant
                 of the same or any other provision.  Landlord's consent or
                 approval in the future.  The acceptance of rent by Landlord is
                 not a waiver of any breach by Tenant other than the failure of
                 Tenant to pay the particular rent accepted, regardless of
                 whether Landlord knows of such a breach.

         24.10   INTEREST ON PAST DUE OBLIGATIONS:  Any amount due to Landlord
                 not paid when due will bear interest from the date due at the
                 prime lending rate in effect from time to time at the Chase
                 Manhattan Bank, N.A., in New York City, or the highest rate of
                 interest payable under the law, whichever is lower.  Payment
                 of interest will not cure any default by Tenant under this
                 Lease except as expressly provided.

         24.11   ATTORNEY'S FEES:  If either party brings an action regarding
                 terms or rights under this Lease, the prevailing party in any
                 action, on trial or appeal, is entitled to reasonable
                 attorney's fees as fixed by the court to be paid by the losing
                 party.  The term "attorney's fees" shall include, but is not
                 limited to, reasonable attorney's fees incurred in any and all
                 judicial, bankruptcy, reorganization, administrative or other
                 proceeding, including appellate proceedings, whether the
                 proceedings arise before or after entry of a final judgment
                 and all costs and disbursements in connection with the matter.

         24.12   WAIVER OF JURY TRIAL:  Landlord and Tenant each waive trial by
                 jury in any action, proceeding, or counterclaim brought by
                 either of the parties to this Lease against the others on any
                 matter whatsoever arising out of or in any way connected with
                 this Lease or its termination, the relationship of Landlord
                 and Tenant,



                                     -12-
   15

                 Tenant's use or occupancy of the Premises, and/or any claim of
                 injury or damage and any emergency statutory or any other
                 statutory remedy.

         24.13   RECORDING:  Tenant will not record this Lease without
                 Landlord's written consent.  Any recordation, at Landlord's
                 option, will constitute a non-curable default of Tenant.

         24.14   SIGNS AND AUCTIONS:  Tenant shall not place any sign upon or
                 conduct any auction on the Premises without Landlord's prior
                 written consent.

         24.15   SECURITY:  Tenant acknowledges that the rents reserved in this
                 Lease do not include the cost of security guards or other
                 security measures, and that Landlord has no obligation to
                 provide such services.  Tenant assumes all responsibility for
                 the protection of Tenant, its agents, employees and invitees
                 from acts of third parties.

         24.16   RELOCATION OF TENANT:  Landlord reserves the right, at its
                 sole option, to relocate Tenant to a comparable space (the
                 Relocation Space) in the Industrial Park.  Landlord may use
                 decorations and materials from the Premises or other materials
                 in making the Relocation Space comparable to the Premises.
                 Neither the Fixed Minimum Rent nor the Tenant's Share
                 percentage shall be changed on account of the move unless it
                 is raised or reduced in accordance with the share percentage
                 for the Relocation Space.  Tenant agrees that no rights
                 granted in this Lease shall be deemed breached by Landlord's
                 exercise of rights under this paragraph.  Landlord shall pay
                 the decoration costs, moving expenses for furniture, fixtures
                 and equipment, utility hookup charges and reasonable actual
                 out-of-pocket expenses incurred by Tenant.

         24.17   EASEMENTS AND RESTRICTIVE COVENANTS:  Landlord reserves the
                 right of grant and record easements, cross-easements, rights,
                 restrictive covenants and conditions and dedications which it
                 deems necessary or desirable.  The grants will not
                 unreasonably interfere with Tenant's use of the Premises.
                 Tenant agrees to promptly execute documents requested by
                 Landlord.  Failure to execute will be a material breach under
                 this Lease.

         24.18   RULES AND REGULATIONS:  Tenant will comply with Landlord's
                 rules and regulations respecting the Industrial Park.  Notice
                 of the rules and regulations will be posted or given to
                 Tenant.

         24.19   BINDING EFFECT, CHOICE OF LAW:  Subject to provisions
                 restricting assignment or subletting and to the provisions of
                 Paragraph 22, this Lease will bind the parties, their personal
                 representatives, successors and assigns.  This Lease shall be
                 governed by the laws of the state in which the Premises are
                 located.

         24.20   ABSENCE OF OPTION:  The submission of this Lease for
                 examination does not constitute a reservation of or an option
                 for the Premises and this Lease becomes effective only upon
                 execution by Landlord.

25.      SPECIAL STIPULATIONS:  Insofar as the following Special Stipulations
         conflict with any of the foregoing provisions, the following Special
         Stipulations shall control.  Special Stipulations, if any, are
         attached hereto and made a part of this Agreement as Exhibit "E".

1.  Landlord hereby agrees to proceed with reasonable diligence to complete
    construction of the Premises or otherwise to prepare the Premises for
    Tenant's occupancy in accordance with the Plans and Specifications.  Tenant
    shall have no right to occupy the Premises until Landlord has notified
    Tenant, in writing, that the work to be done by Landlord has been
    substantially completed, except for minor finishing operations or items
    necessary awaiting performance of any work done by Tenant.  Prior to
    performance of any work to be done by Tenant, a punch list will be prepared
    by Landlord or representative of Landlord, and Tenant.  However, Tenant
    shall have the right to make periodic inspections of the construction, so
    long as Tenant gives Landlord prior notification and complies with
    Landlord's safety rules.  Notwithstanding anything herein to the contrary,
    payment of rental hereunder and Tenant's tenancy shall commence November 1,
    1993 provided that all work required to be performed by Landlord has been
    substantially completed except for punch list items.

2.  Subject to the provisions of the Lease and except as otherwise provided in
    this Lease to the contrary, if Landlord, for any reason whatsoever, shall
    fail to complete a portion of its work in the Premises or to deliver
    possession of the Premises on or before November 1, 1993, this Lease shall
    not be void or voidable, nor shall Landlord be deemed to be in default
    hereunder or in any way liable to Tenant for any loss or damage resulting
    therefrom; provided, however, the Commencement Date of the Term and if
    substantial completion of Landlord's work as hereinabove provide, and the
    termination date of the Term shall be extended for an additional period
    equal to the delay.  In the event Landlord is unable to substantially
    complete Landlord's Work and Tenant is unable to occupy Premises by
    December 31, 1993, Tenant may terminate this Agreement, force majeure
    excepted.

3.  Landlord hereby covenants and agrees to complete the Tenant fit-up and
    finish work (the "Landlord's Work") for the Premises in accordance with the
    Plans and Specifications, provided, however, that Tenant shall be
    responsible for and hereby covenants and agrees to pay any costs without
    limitation incurred by Landlord in completing such Lease fit-up and finish
    work due to any changes in Plans and Specification made after execution of
    this Lease by Tenant.  Landlord warrants that all of such build-out of the
    Premises shall also comply with all laws, orders, ordinances and
    regulations of federal, state, country and municipal authorities having
    jurisdiction over the Premises and Landlord shall promptly comply with any
    directive order or citation made pursuant to such laws during the term of
    this lease.

4.  By occupying the Premises, Tenant shall be deemed to have accepted the
    Premises "as is" and to have acknowledged that the Premises are suited for
    the uses intended by Tenant and that Landlord has complied with all of its
    covenants and obligations with respect to completion of the Premises and
    delivery thereof to Tenant; provided, however, (i) Tenant shall have five
    (5) days after the Commencement Date in which to deliver its "punch list"
    to Landlord and Landlord shall have fifteen (15) days of delivery of the
    "punch list" to begin correcting any defects noted on Tenant's punch list
    which denote items not completed in accordance with the Plans and
    Specifications and diligently pursue their completion: and (ii) Landlord
    shall warrant said construction against defects for one (1) year.  In the
    event of any dispute concerning work performed or required to be performed
    in the Premises by Landlord, the matter in dispute shall be submitted to
    the architect for the Premises for determination, and his determination
    with respect thereto as evidenced by his certificate shall be binding on
    Landlord and Tenant.

5.  Within ten (10) days from the date of execution of the Lease, Landlord
    shall provide Tenant with complete Plans and Specifications for the
    Premises for Tenant's review and approval.  Tenant shall return Plans and
    Specifications approved within five (5) days of receipt of Plans and
    Specifications.

                            SPECIAL STIPULATIONS TO
                      STANDARD INDUSTRIAL LEASE AGREEMENT




BETWEEN:         NATIONAL LIFE INSURANCE COMPANY (LANDLORD)

AND              SPECTRX, INC.

DATED:           SEPTEMBER __, 1993




1.  COMMON AREA MAINTENANCE: Tenant shall pay Landlord Three Hundred Nine and
    16/100 Dollars, ($309.16) per month with the monthly fixed minimum rent
    which is the Landlord's estimate of Tenant's share of the cost of common
    Area Maintenance for 1992 in accordance with paragraph 5.2.

2.  Tenant agrees to adhere to Plaza 85 Business Park Regulations as attached
    hereto and made a part of this Lease.

3.  Tenant agrees to adhere to Plaza 85 Business Park Signage Criteria as
    attached hereto and made a part of this Lease.

4.  Various construction materials may contain items that have been or may in
    the future be determined to be hazardous (toxic) or undesirable and may
    need to be specially treated/handled or removed.  For example, some
    transformers and other electrical components contain PCBs, and asbestos has
    been used in components such as fire-proofing, heating and cooling systems,
    air duct insulation, spray-on and tile acoustical materials, linoleum,
    floor tiles, roofing, dry wall and plaster.  Due to prior or current uses
    of the Property or in the area, the Property may have hazardous or
    undesirable metals, minerals, chemicals, hydrocarbons, or biological or
    radioactive items in soil, water, building components above or below ground
    containers or elsewhere in areas that may or may not be accessible or
    noticeable.  Such items may leak or other wise be released.  Real estate
    agents have no expertise in the detection or correction of hazardous or
    undesirable items.  Expert inspections are necessary.  Current or future
    laws may require clean up by past, present and/or future owners and/or
    operators.  It is the responsibility of the Seller/Landlord and
    Buyer/Tenant to retain qualified experts to detect and correct such matters
    and to consult with legal counsel of their choice to determine what
    provisions, if any, they may wish to include in transaction documents
    regarding the Property.

5.  AMERICANS WITH DISABILITIES ACT DISCLOSURE: The United States Congress has
    recently enacted the Americans With Disabilities Act. Among other things,
    this act is intended to make many business establishments equally
    accessible to persons with a variety of disabilities; modifications to real
    property may be required. State and local laws also may mandate changes.
    The real estate brokers in this transaction are not qualified to advise you
    as to what, if any, changes may be required now, or in the future. Owners
    and tenants should consult the attorneys and qualified design professionals
    of their choice for information regarding these matters. Real estate
    brokers cannot determine which attorneys or design professionals have the
    appropriate expertise in this area.

              1-12                         $3.75                      $3,050.94

             25-36                         $5.25                      $4,271.31
             37-60                         $5.50                      $4,474.71
           

7.  Tenant will have the right to terminate this Lease after the anniversary of
    the Thirty Sixth (36th) full calendar month of this Lease, with One Hundred
    Eighty (180) days prior written notice, provided Tenant is not in default
