good faith to cure such default), then Lessor may terminate this lease on not
less than     days' notice to Lessee. On the date specified in such notice the
term of this lease shall terminate, and Lessee shall then quit and surrender the
premises to Lessor, but Lessee shall remain liable as hereinafter provided. If
this lease shall have been so terminated by Lessor, Lessor may at any time
thereafter resume possession of the premises by any lawful means and remove

lease the sum of Nineteen Hundred Dollars ($1,900) as security for the

this lease.

lease commences, whether because of increased rate or valuation, Lessee shall

                  hereinafter provided. If tenant shall default in the timely
                  payment of any item of rent and such default shall continue or
                  be repeated for four consecutive months or for a total of four
                  months in any period of twelve months, or in the performance
                  of any particular term, condition or covenant of this Lease
                  more than six times in any period of twelve (12) months, then,
                  notwithstanding that such defaults shall have been cured
                  within the period after notice, if any, as provided in this
                  Lease.

                  have been given, and the terms shall expire as aforesaid; or
                  (ii) if any execution or attachment shall be issued against
                  tenant or any of tenant's property whereupon the premises
                  shall be taken or occupied or attempted to be taken or
                  occupied by someone other than tenant; then, and in any of

                           rent and other charges payable under this Lease by
                           tenant to landlord to the date upon which this Lease
                           and the demised term shall have expired and come to
                           an end or to the date of re-entry upon the demised

                           reserved in this Lease for the period which otherwise
                           would have constituted the unexpired portion of the
                           demised terms and the net amount, if any, of rents
                           collected under any reletting effected or any part of
                           such period (first deducting from the rents collected
                           under any such reletting of all landlord's expenses
                           in connection with the termination of this Lease or
                           landlord's re-entry upon the demised premises and
                           with such reletting including, but not limited to,
                           all repossession costs, brokerage commissions, legal

                           Lease for payment of installments of rent. Landlord
                           shall be entitled to recover from tenant each monthly
                           deficiency as the same shall arise, and no suit to
                           collect the amount of the deficiency for any month
                           shall prejudice landlord's rights to collect the

                           monthly deficiencies as aforesaid, landlord shall be
                           entitled to recover from tenant, and tenant shall pay
                           to landlord, on demand, as and for

<PAGE>
               liquidated and agreed final damages, a sum equal to the amount by
               which the rent and additional rent reserved in this Lease for the
               period of the demised term, or any part thereof, the amount of
               rent reserved upon such reletting shall be deemed, prima facie,
               to be the fair and reasonable rental value for the part or the
               whole of demised premises so relet during the term of the
               reletting.

b)   If the demised premises, or any part thereof, shall be relet together with
     other space in the building, the rents collected or reserved under any such
     reletting and the expenses of any such reletting shall be equitably
     apportioned for the purposes of this article. Tenant shall in no event be
     entitled to any rents collected or payable under any reletting, whether or
     not such rents shall exceed the rent reserved in this Lease. Solely for the
     purposes of this Article, the term "rent" shall mean the rent in effect
     immediately prior to the date upon which this Lease and the demised term
     shall have expired and come to an end, or the date of re-entry upon the
     demised premises by landlord, as the case may be, plus any additional rent
     payable immediately preceding such event. Nothing contained in this Lease
     shall be deemed to limit or preclude the recovery by landlord from tenant
     of the maximum amount allowed to be obtained as damages by any statute or
     rule of law, or of any sums or damages to which landlord may be entitled.

46. Attorney's Fees

     If tenant shall at any time be in default hereunder, and if landlord shall
institute an action or summary proceeding against tenant based upon such default
and landlord shall be successful, then tenant shall reimburse landlord for the
expenses of attorney's fees and disbursements incurred by landlord. The amount
of such expenses shall be deemed to be "additional rent" hereunder and shall be
due from tenant to landlord on the first day of the month following the
incurring of such expenses.

46. Eminent Domain

     If the whole of the demised premises shall be taken or condemned by any
competent authority for any public or quasi-public use or purpose, then, and in
that event, the terms of this lease shall cease and terminate from the date when
the possession of the part so taken shall be required for such use or purpose,
and without apportionment of the award; however, the tenant shall have the right
to make a claim for fixture damage. If only a part of the demised premises shall
be taken or obtained by any competent authority for any public or quasi-public
use or purpose, and such taking prevents the conduct of the tenant's business,
then, and in that event, a the option of the landlord or tenant, the term of
this Lease shall cease and terminate from the date when the
<PAGE>
possession of the part so taken shall be required for such use or purpose and
without apportionment of the award. The current rental, however, shall in either
case be apportioned.

48.  Environmental Damage

     Tenant covenants that in addition to normal maintenance, he shall take
special care to insure that no damage be caused to the property as a result of
his use of the premises. Tenant agrees that if any environmental damage is
caused to the property as a result of tenants use, tenant will be responsible
for all cleanup costs and damages. This paragraph shall survive the termination
of this lease.

49.  Tenant shall place its garbage in the dumpster at the rear of the property.
No garbage shall be left in the halls or outside the dumpster. Tenant agrees to
comply with all local recycling regulations and tenant further covenants that
ANY TOXIC WASTE OR MEDICAL WASTE SHALL NOT BE PLACED IN THE DUMPSTER BUT SHALL
BE REMOVED BY A LICENSED CONTRACTOR AT TENANTS SOLE COST.

50.  Landlord is responsible for providing heat, air conditioning, electric and
water to the demised premises on business days Monday to Friday from 8 a.m. to
6 p.m.

51.  Tenants security deposit of $1,900 shall be held by Landlord. Landlord
shall have no obligation to segregate security deposit or to pay interest
thereon.

52.  The demised premises are deemed to be 550 sq feet and the (ILLEGIBLE)
proportionate share for the purpose of this lease is deemed to be 12%.

53.  Any individual executing this lease hereby warrants and covenants that they
have the authority to sign this lease and (ILLEGIBLE) their respective entities.

Lessee hereby offers to lease from Lessor the premises situated in the City of
E. Northport, County of Suffolk, State of N.Y., described as 351 Larkfield Rd.,
upon the following TERMS and CONDITIONS:

1. TERM AND RENT. Lessor demises the above premises for a term of Three years,
commencing Jan, 1, 2002, and terminating on Dec, 31, 2004, or sooner as provided
herein at the annual rental of $28,200.00 Dollars ($2,350 per Month), payable in
equal installments in advance on the first day of each month for that month's
rental, during the term of this lease. All rental payments shall be made to
Lessor, at the address specified above.

2. USE. Lessee shall use and occupy the premises for Computer Software Company.
The premises shall be used for no other purpose. Lessor represents that the
premises may lawfully be used for such purpose.

3. CARE AND MAINTENANCE OF PREMISES. Lessee acknowledges that the premises are
in good order and repair, unless otherwise indicated herein. Lessee shall, at
his own expense and at all times, maintain the premises in good and safe
condition, including plate glass, electrical wiring, plumbing and heating
installations and any other system or equipment upon the premises and shall
surrender the same, at termination hereof, in as good condition as received,
normal wear and tear excepted. Lessee shall be responsible for all repairs
required, excepting the roof, exterior walls, structural foundations, and:

                                                                   , which shall

be maintained by Lessor. Lessee shall also maintain in good condition such
portions adjacent to the premises, such as sidewalks, driveways, lawns and
shrubbery, which would otherwise be required to be maintained by Lessor.

4. ALTERATIONS. Lessee shall not, without first obtaining the written consent of
Lessor, make any alterations, additions, or improvements, in, to or about the
premises.

5. ORDINANCES AND STATUTES. Lessee shall comply with all statutes, ordinances
and requirements of all municipal, state and federal authorities now in force,
or which may hereafter be in force, pertaining to the premises, occasioned by
or affecting the use thereof by Lessee.

6. ASSIGNMENT AND SUBLETTING. Lessee shall not assign this lease or sublet any
portion of the premises without prior written consent of the Lessor, which shall
not be unreasonably withheld. Any such assignment or subletting without consent
shall be void and, at the option of the Lessor, may terminate this lease.

7. UTILITIES. All applications and connections for necessary utility services
on the demised premises shall be made in the name of Lessee only, and Lessee
shall be solely liable for utility charges as they become due, including those
for sewer, water, gas electricity, and telephone services.

8. ENTRY AND INSPECTION. Lessee shall permit Lessor or Lessor's agents to enter
upon the premises at reasonable times and upon reasonable notice, for the
purpose of inspecting the same, and will permit Lessor at any time within sixty
(60) days prior to the expiration of this lease, to place upon the premises any
usual "To Let" or "For Lease" signs, and permit persons desiring to lease the
same to inspect the premises thereafter.

9. POSSESSION. If Lessor is unable to deliver possession of the premises at
the commencement hereof, Lessor shall not be liable for any damage caused
thereby, nor shall this lease be void or voidable, but Lessee shall not be
liable for any rent until possession is delivered. Lessee may terminate this
lease if possession is not delivered within      days of the commencement of
the term hereof.

10. INDEMNIFICATION OF LESSOR: Lessor shall not be liable for any damage or
injury to Lessee, or any other person, or to any property, occurring on the
demised premises or any part thereof, and Lessee agrees to hold Lessor harmless
from any claims for damages, no matter how caused.

11. INSURANCE. Lessee, at his expense, shall maintain plate glass and public
liability insurance including bodily injury and property damage insuring Lessee
and Lessor with minimum coverage as follows:

Lessee shall provide Lessor with a Certificate of Insurance showing Lessor as
additional insured. The Certificate shall provide for a ten-day written notice
to Lessor in the event of cancellation or material change of coverage. To the
maximum extent permitted by insurance policies which may be owned by Lessor or
Lessee, Lessee and Lessor, for the benefit of each other, waive any and all
rights of subrogation which might otherwise exist.

<PAGE>
12. EMINENT DOMAIN. If the premises or any part thereof or any estate therein,
or any other part of the building materially affecting Lessee's use of the
premises, shall be taken by eminent domain, this lease shall terminate on the
date when title vests pursuant to such taking. The rent, and any additional
rent, shall be apportioned as of the termination date, and any rent paid for
any period beyond that date shall be repaid to Lessee. Lessee shall not be
entitled to any part of the award for such taking or any payment in lieu
thereof, but Lessee may file a claim for any taking of fixtures and
improvements owned by Lessee, and for moving expenses.

13. DESTRUCTION OF PREMISES. In the event of a partial destruction of the
premises during the term hereof, from any cause, Lessor shall forthwith repair
the same, provided that such repairs can be made within sixty (60) days under
existing governmental laws and regulations, but such partial destruction shall
not terminate this lease, except that Lessee shall be entitled to a
proportionate reduction of rent while such repairs are being made, based upon
the extent to which the making of such repairs shall interfere with the
business of Lessee on the premises. If such repairs cannot be made within said
sixty (60) days, Lessor, at his option, may make the same within a reasonable
time, this lease continuing in effect with the rent proportionately abated as
aforesaid, and in the event that Lessor shall not elect to make such repairs
which cannot be made within sixty (60) days, this lease may be terminated at
the option of either party. In the event that the building in which the demised
premises may be situated is destroyed to an extent of not less than one-third
of the replacement costs thereof, Lessor may elect to terminate this lease
whether the demised premises be injured or not. A total destruction of the
building in which the premises may be situated shall terminate this lease.

14. LESSOR'S REMEDIES ON DEFAULT. If Lessee defaults in the payment of rent, or
any additional rent, or defaults in the performance of any of the other
covenants or conditions hereof, Lessor may give Lessee notice of such default
and if Lessee does not cure any such default within -10- days, after the giving
of such notice (or if such other default is of such nature that it cannot be
completely cured within such period, if Lessee does not commence such curing
within such -10- days and thereafter proceed with reasonable diligence and in
good faith to cure such default), then Lessor may terminate this lease on not
less than     days' notice to Lessee. On the date specified in such notice the
term of this lease shall terminate, and Lessee shall then quit and surrender
the premises to Lessor, but Lessee shall remain liable as hereinafter provided.
If this lease shall have been so terminated by Lessor, Lessor may at any time
thereafter resume possession of the premises by any lawful means and remove
Lessee or other occupants and their effects. No failure to enforce any term
shall be deemed a waiver.

15. SECURITY DEPOSIT. Lessee shall deposit with Lessor on the signing of this
lease the sum of -Forty Seven Hundred- Dollars ($4,700.00) as security for the
performance of Lessee's obligations under this lease, including without
limitation the surrender of possession of the premises to Lessor as herein
provided. If Lessor applies any part of the deposit to cure any default of
Lessee, Lessee shall on demand deposit with Lessor the amount so applied so
that Lessor shall have the full deposit on hand at all times during the term of
this lease.

16. TAX INCREASE. In the event there is any increase during any year of the
term of this lease in the City, County or State real estate taxes over and
above the amount of such taxes assessed for the tax year during which the term
of this lease commences, whether because of increased rate or valuation, Lessee
shall pay to Lessor upon presentation of paid tax bills an amount equal to
-28-% of the increase in taxes upon the land and building in which the leased
premises are situated. In the event that such taxes are assessed for a tax year
extending beyond the term of the lease, the obligation of Lessee shall be
proportionate to the portion of the lease term included in such year.

17. COMMON AREA EXPENSES. In the event the demised premises are situated in a
shopping center or in a commercial building in which there are common areas,
Lessee agrees to pay his pro-rata share of maintenance, taxes, and insurance
for the common area.

18. ATTORNEY'S FEES. In case suit should be brought for recovery of the
premises, or for any sum due hereunder, or because of any act which may arise
out of the possession of the premises, by either party, the prevailing party
shall be entitled to all costs incurred in connection with such action,
including a reasonable attorney's fee.

19. WAIVER. No failure of Lessor to enforce any term hereof shall be deemed to
be a waiver.

20. NOTICES. Any notice which either party may or is required to give, shall be
given by mailing the same, postage prepaid, to Lessee at the premises, or
Lessor at the address specified above, or at such other places as may be
designated by the parties from time to time.

21. HEIRS, ASSIGNS, SUCCESSORS. This lease is binding upon and inures to the
benefit of the heirs, assigns and successors in interest to the parties.

of this lease, Lessee shall have the option to renew the lease for an additional
term of 36 months commencing at the expiration of the initial lease term. All of
the terms and conditions of the lease shall apply during the renewal term except
that the monthly rent shall be increased 8% per annum. The option shall be
exercised by written notice given to Lessor not less than -Ninety- days prior to
the expiration of the initial lease term. If notice is not given in the manner
provided herein within the time specified, this option shall expire.

23. SUBORDINATION. This lease is and shall be subordinated to all existing and
future liens and encumbrances against the property.

following disclosure: "Radon Gas" is a naturally occurring radioactive gas

     premises.

28.      Sign

         The tenant may, subject to the landlord's prior written approval,
     which shall not be unreasonably withheld, erect an outdoor sign on the
     premises to advertise the tenant's business. Any such sign must be in
     compliance with law and with the rules and regulations of all governmental

condone or authorize late payment or rent.

         Any check remitted to the landlord that fails to "clear" in the
banking process for any reason whatsoever, except provable bank error, will
cause a $25.00 service charge to be added to tenant's account as additional
rent and, on the third (3rd) such default, will cause all rent to accelerate,
causing the entire year's rent to be presently due and payable.

31.      Partial Invalidity

circumstances shall to any extent be invalid, the remainder of this Lease or

                           collected under any reletting effected or any part of

                           in connection with the termination of this Lease or

                           shall be entitled to recover from tenant each monthly
                           deficiency as the same shall arise, and no suit to

<PAGE>
               liquidated and agreed final damages, a sum equal to the amount by
               which the rent and additional rent reserved in this Lease for the
               period of the demised term, or any part thereof, the amount of
               rent reserved upon such reletting shall be deemed, prima facie,
               to be the fair and reasonable rental value for the part or the
               whole of demised premises so relet during the term of the
               reletting.

b)   If the demised premises, or any part thereof, shall be relet together with
     other space in the building, the rents collected or reserved under any such
     reletting and the expenses of any such reletting shall be equitably
     apportioned for the purposes of this article. Tenant shall in no event be
     entitled to any rents collected or payable under any reletting, whether or
     not such rents shall exceed the rent reserved in this Lease. Solely for the
     purposes of this Article, the term "rent" shall mean the rent in effect
     immediately prior to the date upon which this Lease and the demised term
     shall have expired and come to an end, or the date of re-entry upon the
     demised premises by landlord, as the case may be, plus any additional rent
     payable immediately preceding such event. Nothing contained in this Lease
     shall be deemed to limit or preclude the recovery by landlord from tenant
     of the maximum amount allowed to be obtained as damages by any statute or
     rule of law, or of any sums or damages to which landlord may be entitled.

46. Attorney's Fees

     If tenant shall at any time be in default hereunder, and if landlord shall
institute an action or summary proceeding against tenant based upon such default
and landlord shall be successful, then tenant shall reimburse landlord for the
expenses of attorney's fees and disbursements incurred by landlord. The amount
of such expenses shall be deemed to be "additional rent" hereunder and shall be
due from tenant to landlord on the first day of the month following the
incurring of such expenses.

47. Eminent Domain

     If the whole of the demised premises shall be taken or condemned by any
competent authority for any public or quasi-public use or purpose, then, and in
that event, the terms of this lease shall cease and terminate from the date when
the possession of the part so taken shall be required for such use or purpose,
and without apportionment of the award; however, the tenant shall have the right
to make a claim for fixture damage. If only a part of the demised premises shall
be taken or condemned by any component authority for any public or quasi-public
use or purpose, and such taking prevents the conduct of the tenant's business,
then, and in that event, at the opinion of the landlord or tenant, the term of
this Lease shall cease and terminate from the date when the
<PAGE>
possession of the part so taken shall be required for such use or purposem and
without apportionment of the award. The current rental, however, shall in either
case be apportioned.

48.  Environmental Damage

     Tenant covenants that in additional to normal maintenance, he shall take
special care to insure that no damage be caused to the property as a result of
his use of the premises. Tenant agrees that if any environmental damage is

for all cleanup costs and damages. This paragraph shall survive the termination
of this lease.

water to the demised premises on business days Monday to Friday from 8 a.m. to

shall have no obligation to segregate security deposit or to pay interest
thereon.

52.  The demised premises are deemed to be 1,600 sq feet and the tenan
proportionate share for the purpose of this lease is deemed to be -28%-.

53.  Any individual executing this lease hereby warrants and covenants that they
have the authority to sign this lease and bind their respective entities.

54.  The second years rent will be $2,941.00 starting Jan, 01, 2003 the third
year's rent will be $2,640.46 starting Jan, 01, 2004.
