The term "common facilities" as used herein shall be construed to include those
facilities within the commercial center which are for the nonexclusive use of
Lessee in common with other authorized users, and shall include, but not be
limited to, sidewalks, parking areas, planted areas, open means of ingress and
egress and any signage advertising the common name given to the commercial
center.

     demised premises for Lessee's use and occupancy as shown on said Exhibit A,
     such demised premises to be constructed in accordance with plans and





     specifications to be prepared by Lessor, at Lessor's sole expense, and 
     approved by Lessee.

B.   Commencement of construction. Lessor will commence the construction of such

     be in a form substantially similar to the attached Exhibit "C."

C.   Construction delays and work stoppages. No delay in the completion of the
     construction herein required of Lessor, caused by government regulations,
     inability to procure labor or materials, strikes, acts of God, or other
     causes similar or dissimilar beyond the control of Lessor shall be a basis
     of a claim of lack of diligence on the part of Lessor.

     hours after receipt of written notice of any material violation by Lessee
     or its employees or agents of any such rules or regulations to cure such
     violation such failure shall constitute a default under this lease.

     perils covered by the insurance provided for in Section Seventeen A and D
     of this lease, notwithstanding the fact that such peril shall have been
     caused by the fault or negligence of the other party or anyone for whom

                                SECTION THIRTEEN
                   CASUALTY DAMAGE; REPAIR; ABATEMENT OF RENT

A.   Use of partially damaged premises. In the event of partial damage or
     destruction of the demised premises Lessee shall continue to utilize the
     premises for the operation of its business to the extent that it may be
     practicable to do so.

B.   Right to terminate on destruction of premises where damage exceeds one-half
     of reconstruction cost. Either party hereto shall have the right to
     terminate this lease if, during the last nine (9) months of the term
     hereof, the demised premises are damaged to an extent exceeding one-half of
     the reconstruction cost of such restored building as a whole; provided
     that, in such an event, such termination of this lease shall be effected by
     written notice to that effect to the other party delivered within thirty
     (30) days of the happening of such casualty causing the damage.

C.   Repairs by Lessor. If the demised premises shall, either prior to the
     beginning of or during the term hereof, be damaged or destroyed by fire or
     by any other cause whatsoever beyond Lessee's control, Lessor, except as
     hereinafter otherwise provided, shall immediately on receipt of insurance
     proceeds paid in connection with such casualty insurance, but in no event
     later than ninety (90) days after such damage has occurred, proceed to
     repair or rebuild same, including any additions or improvements made by
     Lessor or by Lessee with Lessor's consent, on the same plan and design as
     existed immediately before such damage or destruction occurred, subject to
     such delays as may be reasonably attributable to governmental restrictions
     or failure to obtain materials or labor, or other causes whether similar or
     dissimilar, beyond the

                                        9





     control of Lessor. Materials used in repair shall be nearly like original
     materials as may be reasonably procured in regular channels of supply.
     Notwithstanding the foregoing, all said repairs must be substantially
     completed within two hundred seventy (270) days from the date of casualty
     or Lessee has the right to terminate this lease. Lessee's right to
     terminate this lease shall be exercised in writing on or before the two
     hundred seventy-fifth (275th) day from the date of casualty or it shall
     automatically be deemed to be waived.

     Whenever a strike, act of God or cause, beyond the power of the party
     affected to control, causes delay, the period of such delay so caused shall
     be added to the period limited in this lease for the completion of such
     work, reconstruction or replacement.

D.   Reduction of rent during repairs. In the event Lessee continues to conduct
     its business during the making of repairs, the fixed minimum monthly rental
     will be equitably reduced in the proportion that the unusable part of the
     demised premises bears to the whole thereof but no change shall be made in
     the method of computing the additional rental and additional charges due
     from Lessee under the terms of this lease.

     No rent shall be payable while the demised premises are thirty percent
     (30%) or more untenantable pending the repair of casualty damage.

E.   Repair or replacement of fixtures. Lessee shall be responsible for the
     replacement or repairs of its fixtures in the demised premises which may be
     damaged or destroyed by fire or any other cause whatsoever.

                                SECTION FOURTEEN

Lessee shall pay before delinquency all taxes levied or assessed on Lessee's
fixtures, equipment and personal property in and on the demised premises,
whether or not affixed to the real property.

If at any time after any tax or assessment has become due or payable, Lessee or
its legal representative neglects to pay such tax or assessment, Lessor shall be
entitled to pay the same at any time thereafter and such amount so paid by
Lessor shall be deemed to be additional rent for the leased premises, due and
payable by Lessee.

Lessor shall initially pay all general real estate taxes and special assessments
levied and/or assessed against the lot and building in which the demised
premises is situated, the parking areas and landscaped areas associated with
that building and the entire commercial center during the term of this lease,
subject, however, to Lessee's reimbursement of said charges as is provided in
Section Four of this lease.

                                SECTION SEVENTEEN
                                    INSURANCE

A.   Insurance companies. All policies of insurance to be kept and maintained in
     force by the respective parties hereto shall be obtained from good and
     solvent insurance companies reasonably satisfactory to Lessor with Lessor
     named as an additional insured party under the liability insurance. Lessee
     shall annually provide Lessor, on the anniversary date of this lease, with
     a certificate naming Lessor as said additional insured party.


                                       11





B.   Lessee to obtain liability insurance. Lessee shall, at its own expense, at
     all times during the term of this lease, maintain in force a policy or
     policies of insurance, written by one or more responsible insurance
     carriers which will insure Lessor and Lessee against liability for injury
     to or death of persons or loss of damage to property occurring in or about
     the demised premises. The liability under such insurance shall not be less
     than One Million Dollars ($1,000,000) for any one person killed or injured,
     One Million Dollars ($1,000,000) for any one accident, and Five Hundred
     Thousand Dollars ($500,000) property damage.

C.   Lessee to obtain fire insurance on its fixtures and equipment. Lessee shall
     maintain in force, at all times during the term of this lease, on all of
     its fixtures and equipment in the demised premises, such policies as it
     deems adequate for the repair and replacement thereof.

D.   Lessor to obtain fire insurance on premises. Lessor shall maintain in force
     and shall pay for, at all times the term of this lease, policies of
     casualty insurance in such amounts as shall be determined solely by Lessor.

E.   Lessee's waiver of Lessor's casualty insurance proceeds. In the event the
     demised premises shall be damaged or destroyed by fire, or other casualty
     so insured against, Lessee shall claim no interest in any insurance
     settlement arising out of any such loss and shall execute any and all
     documents required by Lessor or the insurance company or companies that may
     be necessary for use in connection with settlement of any such loss by
     Lessor.

                                SECTION EIGHTEEN
                    TRANSFER OR PLEDGE OF LEASEHOLD INTEREST

Lessee shall not assign this lease or any interest therein, or sublet the
demised premises or any part thereof, or license the use of any portion of the
demised premises or business conducted thereon or therein, or encumber or
hypothecate this lease, without first obtaining the written consent of Lessor,
which consent will not be unreasonably withheld, conditioned or delayed. Any
assignment, subletting, licensing, encumbering or hypothecating of this lease
without such prior written consent shall, at the option of Lessor, immediately
terminate this lease. Notwithstanding the foregoing, the parties agree (i)
Lessee may assign this lease or sublet the demised premises to any affiliate of
Lessee which has substantially common ownership as Lessee ("Affiliate") without
Lessor's written consent; and (ii) in the event Lessee assigns this lease or
sublets the demised premises to an Affiliate any profit derived by Lessee from
said assignment or sublet shall inure to the benefit of Lessee.


                                       12





                                SECTION NINETEEN
                              SURRENDER OF PREMISES

Lessee shall, at the termination of this lease, vacate the demised premises in
as good condition as it was at the time of entry thereon by Lessee, except for
reasonable use and wear thereof, acts of God, or damage by casualty beyond the
control of Lessee, and on vacating shall leave the demised premises free and
clear of all rubbish and debris.

                                 SECTION TWENTY
                            INDEMNIFICATION OF LESSOR

A.   Liens and encumbrances. Lessor and Lessee respectively (respectively, the
     "Indemnifying Party") shall indemnify the other and the premises herein
     demised and all improvements placed thereon against all claims, liens,
     claims of lien, demands, charges, encumbrances or litigation arising
     directly or indirectly out of or by reason of any work or activity of the
     Indemnifying Party on the demised premises, and shall forthwith and within
     fifteen (15) days after the filing of any lien for record fully pay and
     satisfy the same, and shall reimburse the other party for all loss, damage
     and expense, including reasonable attorneys' fees, which it may suffer or
     be put to by reason of any such claims of lien, demands, charges,
     encumbrances or litigation.

     In the event the Indemnifying Party shall fail to pay and fully discharge
     any claim, lien, claims of lien, demand, charge, encumbrance or litigation,
     or should proceedings be instituted for the foreclosure of any lien or
     encumbrance, the other party shall have the right, at its option, at any
     time after the expiration of such 15-day period, to pay the same or any
     portion thereof, with or without the costs and expenses claimed by such
     claimant, and in making such payment the other party shall be the sole
     judge of the legality thereof. All amounts so paid by the other party shall
     be repaid by the Indemnifying Party to the other party on demand, together
     with interest thereon at the rate of eighteen percent (18%) per annum, from
     the date of payment by the other party until repayment is fully made.

B.   Personal injuries, violation of law. Excluding intentional or negligent
     acts of Lessor, Lessee shall indemnify Lessor and its members against any
     cost, liability or expense arising out of any claims of any person or
     persons whatsoever by reason of the use or misuse of the demised premises,
     parking area or common facilities by Lessee or any person or persons
     holding under Lessee, and shall indemnify Lessor against any penalty,
     damage or charge incurred or imposed by reason of any violation of law or
     ordinance by Lessee or any person or persons holding under Lessee, against
     any costs, damage or

                                       13





     expense arising out of the death of or injury to any person or persons
     holding under Lessee.

                               SECTION TWENTY-ONE
                             SUBORDINATION OF LEASE

Upon receipt of a reasonably acceptable non-disturbance agreement, Lessee shall
execute any instrument permitting mortgages or deeds of trust to be placed on
the lot and building in which the demised premises is located or any part
thereof as security for any indebtedness, and subordinate this lease to such
mortgages or trust deeds, if required to do so by the secured party.

Lessee shall have the right to make payment of any defaults under any mortgage,
trust deeds or liens of record on the demised premises, and to receive
reimbursement for such payment by deduction and credit from and against rentals
becoming due hereunder.

                               SECTION TWENTY-TWO
                              ESTOPPEL CERTIFICATE

Lessee agrees to at any time and from time to time, within twenty (20) days
after Lessee's receipt of Lessor's written request, to execute, acknowledge and
deliver without charge to Lessor a written instrument, certifying the
commencement date of the term of this lease, that Lessee has accepted possession
of the demised premises and is open for business, that this lease is unmodified
and in full force and effect (or if there have been modifications, that it is in
full force and effect as modified and stating the modifications), the dates to
which base rent, additional rent and other charges have been paid in advance, if
any, and stating whether or not to the best knowledge of the signer of such
certificate, Lessor is in default in the performance of any covenant, agreement
or condition contained in this lease and, if so, specifying each such default of
which the signer may or should have knowledge, and certifying such other matters
as may be reasonably requested by Lessor ("Estoppel Certificate").

Lessee's failure to deliver an Estoppel Certificate to Lessor within twenty (20)
days after Lessor's written request therefor, shall at the option of Lessor, be
conclusive upon Lessee that: (1) this lease is in full force and effect without
modification except as may be represented by Lessor; (2) that there are no
uncured defaults in Lessor's performance; and (3) that no more than one (1)
month's rent has been paid in advance.


                                       14





                              SECTION TWENTY-THREE
                          LESSOR'S RIGHT OF INSPECTION

Upon notice, except in the case of emergencies, Lessor shall have access to the
demised premises, and each part thereof, during Lessee's regular business hours
and at any time thereafter for the purpose of inspecting the same, making
repairs and posting notices which Lessor may deem to be for the protection of
Lessor or the demised property.

                               SECTION TWENTY-FOUR
                            DEFAULT AND LATE CHARGES

A.   Lessor's right to repossess, operate, or relet. If the rental reserved by
     this lease or other charges to be paid hereunder by Lessee, or any part
     thereof, are not paid when due and shall remain unpaid for a period of ten
     (10) days after notice thereof in writing, or if Lessee shall fail to
     promptly perform any other covenant, condition, or provision by it to be
     performed hereunder and such failure shall continue for a period of ten
     (10) days after receipt of notice in writing specifying the nature of such
     failure, or if Lessee abandons the demised premises and ceases to pay rent,
     then, and in any such event, Lessee shall be deemed to be in default and
     Lessor, without further notice, may at its option re-enter and take
     possession of the demised premises, including all improvements thereon and
     fixtures and equipment owned or leased by Lessee and located at, in or
     about the same, and take, operate or relet the same in whole or in part for
     the account of Lessee at such rental and on such agreement and conditions
     and to such tenant or tenants as Lessor in good faith may deem proper for a
     term not exceeding the unexpired period of the full term of this lease.
     Lessor shall receive all proceeds and rent accruing from such operation or
     reletting of the demised premises or fixtures and equipment and shall apply
     the same first to the payment of all costs and expenses incurred by Lessor
     in obtaining possession and in the operation or reletting of the demised
     premises or fixtures and equipment, including reasonable attorneys' fees,
     commissions, and collection fees, and any alterations or repairs reasonably
     necessary to enable Lessor to operate or relet the premises or fixtures and
     equipment and to the payment of all such amounts as may be due or become
     payable under the provisions of this lease, and the balance remaining, if
     any, at the expiration of the full term of this lease or on the sooner
     termination thereof by written notice of termination given by Lessor to
     Lessee shall be paid over to Lessee. Upon three (3) days' notice to Lessee,
     Lessor may dispose of any personal property of Lessee located at the
     demised premises at the time of any default without incurring any liability
     for such a disposition. Notwithstanding anything contained herein to the
     contrary, it is understood and agreed that in the event Lessee's default
     hereunder cannot be completely cured within said ten (10) day period but
     Lessee has diligently

                                       15





     commenced curing the subject default, Lessee may with reasonable diligence
     and in good faith proceed to remedy or cure the subject default.

B.   Late Charges. If the rental reserved by this lease or other charges to be
     paid hereunder by Lessee, or any part thereof, are not paid when due, late
     charges in the amount of five percent (5%) of the basic monthly rent shall
     be immediately due for each ten-day period, commencing the first (1st) day
     of the applicable month, that the rental or other charges, or any part
     hereof, remain unpaid.

C.   Repossession or reletting not a termination, Lessor's right to terminate
     not forfeited. No re-entry, repossession, operation or reletting of the
     demised premises or of fixtures and equipment shall be construed as an
     election by Lessor to terminate this lease unless a written notice of such
     intention is given by Lessor to Lessee, and notwithstanding any such
     operation or reletting without terminating this lease, Lessor may at any
     time thereafter elect to terminate this lease in the event at such time
     Lessee remains at default hereunder.

D.   Lessee's obligation to pay deficiencies. In the event the proceeds or
     rentals received by Lessor under the provisions of this section are
     insufficient to pay all costs and expenses and all amounts due and becoming
     due hereunder, Lessee shall pay to Lessor on demand such deficiency as may
     from time to time occur or exist.

E.   Lessor's right to perform Lessee's duties at Lessee's cost. Notwithstanding
     any provision as to notice contained in this lease, if in the judgment of
     Lessor the continuance of any material default by Lessee, other than for
     the payment of money, for the full period of the notice otherwise provided
     for will jeopardize the premises or the rights of Lessor, Lessor may,
     without notice, elect to perform those acts in respect of which Lessee is
     in material default, at the expense of Lessee, and Lessee shall thereupon
     reimburse Lessor, with interest at the rate of eighteen percent (18%) per
     annum, on five (5) days notice by Lessor to Lessee.

F.   Lessor's right to terminate lease. In the event of Lessee's material
     default as stated herein, Lessor may, at its option, on five (5) days
     notice, terminate this lease and any and all interest of Lessee hereunder,
     and may thereupon immediately re-enter and take possession of the demised
     premises.

G.   Lessor's right on termination to recover amount equal to rent reserved. If
     this lease is terminated by Lessor by reason of any material default by
     Lessee, Lessor shall be entitled to recover from Lessee, at the time of
     such termination, the excess, if any, of the amount of rent reserved in
     this lease for the balance

                                       16





     of the term thereof over the then reasonable rental value of the premises
     for the same period. It is agreed that the "reasonable rental value" shall
     be the amount of rental which Lessor can obtain as rent for the remaining
     balance of the term.

H.   Lessor's and Lessee's remedies cumulative. Each and all of the remedies
     given to Lessor and Lessee in this lease or by law shall be cumulative, and
     the exercise of one right or remedy by either party shall not impair that
     party's right to exercise any other right or remedy it may possess.

I.   Lessee's waiver of claims against Lessor. Lessee hereby waives all claim or
     demand for damages that may be caused by Lessor in lawfully and rightfully
     re-entering and taking possession of the demised premises as hereinabove
     provided, and all claim or demand for damages which may result from the
     destruction of or damage to the demised premises and all claim or demand
     for damages or loss of property belonging to Lessee as may be in or on the
     premises at the time of such re-entry, assuming Lessor has used reasonable
     care when re-entering and taking possession of the demised premises.

J.   Limitation of notice period by governmental order. Notwithstanding any
     provision as to notice in this section, if Lessee is required to comply
     with any governmental regulation or order within a period less than that to
     which Lessee would otherwise be entitled to notice, Lessee shall not be
     entitled to notice beyond the period within which such compliance may be
     required by such regulation or order.

                               SECTION TWENTY-FIVE
                             EXPENSES OF ENFORCEMENT

Should Lessor or Lessee incur any expenses in enforcing any provision of this
lease the defaulting party shall pay to the non-defaulting party all expenses so
incurred, including reasonable attorneys' fees and court costs.

                               SECTION TWENTY-SIX
                              EFFECT OF BANKRUPTCY

If at any time during the term of this lease there shall be filed by or against
Lessee in any court, pursuant to any statute either of the United States or any
state, petition in bankruptcy or insolvency or for reorganization or for the
appointment of a receiver or trustee of all or a portion of Lessee's property,
or if Lessee makes an assignment for the benefit of creditors, Lessee shall have
breached this lease, and this lease, at the option of Lessor exercised after
expiration of the period provided below, may be cancelled and terminated,
provided such petition in bankruptcy or insolvency or for reorganization or for
the appointment of a receiver or trustee shall continue for a

                                       17





period of ten (10) days. In such event neither Lessee, nor any person claiming
through or under Lessee by virtue of any statute or of any statute or of an
order of any court, shall be entitled to possession or to remain in possession
of the demised premises, but shall forthwith quit and surrender the premises.

                              SECTION TWENTY-SEVEN
                                 EMINENT DOMAIN

A.   Over certain percentage taken. In the event twenty-five percent (25%) or
     more of the area of the demised premises shall be taken for a public or
     quasi-public use this lease shall terminate as of the date of the actual
     physical taking, and the parties shall thereupon be released from any and
     all further liability hereunder.

B.   Less than a certain percentage taken. In the event of a partial taking of
     less than twenty-five percent (25%) of the area of the demised premises,
     Lessor shall, with reasonable diligence, proceed at its own expense to
     reconstruct or repair the demised premises and place the same in a
     tenantable condition within ninety (90) days after the date of the actual
     physical taking, provided, however, that if fifty percent (50%) or more of
     the area of the commercial center as a whole is taken, Lessor alternatively
     may elect to terminate this lease notwithstanding that less than
     twenty-five percent (25%) of the area of the demised premises were taken.
     In the event of such termination the parties hereto shall be released from
     any and all further liability under this lease.

C.   Abatement of rent. During any reconstruction or repairing as hereinabove
     provided, Lessee shall be required to pay only that proportion of the fixed
     minimum monthly rental herein reserved as the area of the demised premises
     remaining in a tenantable condition during such reconstruction or repairing
     bears to the entire area herein leased. On completion of such
     reconstruction or repairing, the fixed minimum monthly rental herein
     reserved shall be adjusted in the proportion that the reconstructed demised
     premises bear to the original demised premises, and thereafter Lessee shall
     be required to pay such adjusted fixed minimum monthly rental in accordance
     with the provisions of this lease.

     There shall be no abatement of any rental due until such time as there
     shall be an actual physical possession of that portion of the demised
     premises taken, and in no event shall there be any change made in the
     method of computing the percentage rental, and there shall be no reduction
     of percentage rental.

D.   Right to condemnation award. Any award made in any condemnation proceeding
     for the taking of any part or all of the demised premises shall be the sole
     property of and be paid to Lessor.


                                       18





                              SECTION TWENTY-EIGHT
                                 QUIET ENJOYMENT

Lessor hereby covenants and warrants that, subject to any trust deeds or
mortgages now of record or hereafter placed on record, it is the owner of the
demised premises and that Lessee, on payment of rents herein provided for and
performance of the provisions hereof on its part to be performed, shall and may
peacefully possess and enjoy the demised premises during the term hereof without
any interruption or disturbance.

                               SECTION TWENTY-NINE
                                WAIVER OF BREACH

No waiver of any breach or breaches of any provision of this lease shall be
construed to be a waiver of any preceding or succeeding breach of such provision
or of any other provision hereof.

                                 SECTION THIRTY
                               TIME OF THE ESSENCE

Time is of the essence of each and every provision hereof.

                               SECTION THIRTY-ONE
                          HEADINGS FOR CONVENIENCE ONLY

                                    PRONOUNS

Feminine or neuter pronouns shall be substituted for those of masculine form or
vice versa, and the plural shall be substituted for the singular number or vice
versa in any place or places in which the context may require such substitution
or substitutions.

                              SECTION THIRTY-THREE
                           AMENDMENTS TO BE IN WRITING

This lease may be modified or amended only by a writing duly authorized and
executed by both Lessor and Lessee. It may not be amended or modified by oral
agreements or understandings between the parties unless the same shall be
reduced to writing duly authorized and executed by both Lessor and Lessee.

                               SECTION THIRTY-FOUR
                                  PARTIES BOUND

Each and every provision of this lease shall bind and shall inure to the benefit
of the parties hereto and their legal representatives. The term "legal
representatives" is used in this lease in its broadest possible meaning and
includes, in addition to executors and administrators, every person,
partnership, corporation or association succeeding to the interest or to any
part of the interest in or to this lease or in or to the leased premises, of
either Lessor or Lessee herein, whether such succession results from the act of
a party in interest, occurs by operation of the law or is the effect of the
operation of law together with the act of such party. Each and every agreement
and condition of this lease by Lessee to be performed shall be binding on all
assignees, subtenants, concessionaires, and/or licensees of Lessee; provided
however, that this provision shall not be deemed to supersede the restrictions
on assignment, subletting or licensing imposed by Section Eighteen entitled
"Transfer or Pledge of Leasehold Interest."

                               SECTION THIRTY-FIVE
                                  HOLDING OVER

No holding over and continuation of any business by Lessee after the expiration
of the term hereof shall be considered to be a renewal or extension of this
lease unless written approval of such holding over and a definite agreement to
such effect is signed by Lessor defining the length of such additional term. Any
holding over without the consent of Lessor shall be considered to be a
day-to-day tenancy at a rental of one hundred fifty percent (150%) of the fixed
minimum monthly rental provided herein, computed on the basis of a 30-day month.

                               SECTION THIRTY-SIX
                                     NOTICES
