NOW, THEREFORE, the parties hereto, for good and valuable
consideration and intending to be legally bound, agree as follows:

1.     The Landlord and Tenant agree to reduce the 24,050 square foot
area currently leased by Tenant to a total area leased by Tenant of
15,200 square feet as shown on the attached Addendum "D-1".

2.     Tenant acknowledges that Tenant will perform all improvements

space from the area to be returned to Landlord including but not
limited to:

   a.   dividing the electric (separate);
   b.   separating the HVAC;
   c.   removing computer wires from the ceiling;
   d.   installing the demising walls;
   e.   obtaining a building permit from the Township of West Windsor;
   f.   obtaining the necessary architectural drawings.

     The Effective Date shall be the latter to occur of (i) June 30,
2006, which is the original expiration date of this Lease, or (ii) the
date Tenant obtains its final certificate of occupancy for the reduced
space but in no event later than August 31, 2006.

     The area to be returned to Landlord shall be returned to Landlord
in "broom clean" condition with all Tenant's equipment and fixtures
removed, including the modular office located at the front right
corner of the 2nd floor and as otherwise required by Paragraph Fifth
of the Lease.

     If any tenant who leases either a portion of or the entire area
returned to Landlord requires access to the existing telephone and
electric rooms, Tenant will make the areas available to the new
tenant(s) at no cost to the tenant(s).

3.     A new five (5) year term for the 15,200 square feet shall
commence upon the Effective Date and terminate five (5) lease years
thereafter.  The rents for the new five (5) year term shall be as
follows:

Year 1 - $174,800.04 per year/$14,566.67 per month/$11.50 per RSF

Year 5 - $205,200.00 per year/$17,100.00 per month/$13.50 per RSF

All of the above monthly installments of rent shall be due on the
first day of each month.  Tenant further understands that the above
figures do not include the taxes, insurance and maintenance
reimbursements and the management fee (TIM) as called for in Paragraph
31st of the above Lease, which shall continue to be due and payable
based upon the reduced area of 15,200 square feet, in addition to the
rent.

     Windsor Business Park currently consists of four (4) buildings
totaling approximately 93,023 rentable square feet, which will change
from time to time as additional buildings are constructed or the
existing buildings are altered.  A fifth approximately 26,466 rentable
square foot building has been approved and will be constructed as the
third building on Block 21.04 Lot 1 where shown on the attached
Addendum "B-1".  It is agreed between the Landlord and the Tenant that
the Tenant's pro rata share of taxes insurance and maintenance
reimbursement to be paid by Tenant to Landlord is currently as
follows:

            Maintenance.  Tenant's pro rata share for the maintenance
reimbursements to be paid by Tenant to Landlord which is currently
based on the four (4) buildings at Windsor Business Park will be
reduced to 16.34% (15,200 SF divided by 93,023 SF).  Tenant's pro rata
share will be revised when a third approximately 26,466 rentable
square foot building is constructed on Block 21.04 Lot 1.

            Insurance.  Tenant's pro rata share of the insurance
reimbursement to be paid by Tenant to Landlord is currently based on

Block 21.04 Lot 1.

            Taxes.  Tenant's pro rata share for the real estate taxes
and assessments reimbursement to be paid by Tenant to Landlord which
is currently based on the two buildings (Building 3 and Building 4) on
Block 24.01 Lot 1 at Windsor Business Park will be changed to 35.14%
(15,200 SF divided by 43,253 SF).  Tenant's pro rata share will be
revised when a third approximately 26,466 rentable square foot
building is constructed on Block 21.04 Lot 1.

4.     The Option to Renew the Lease set forth in Paragraph 68th of
Addendum "A" to Lease is intentionally deleted.

5.     Upon the Effective Date, Tenant shall release all right and
interest in the balance of its premises other than the 15,200 square
foot space, and Landlord and Tenant do hereby mutually release each
other and their officers, directors, employees, subsidiaries and
affiliates, successors and assigns of and from all liability,
responsibilities, claims, demands, actions and causes of action of
every kind and nature whatsoever ("Claims") arising out of Tenant's

and hold Landlord harmless from any and all loss, liabilities,
expenses, costs, claims or damages by any person or firm claiming to
have negotiated or brought about this lease extension.   Landlord will
give prompt notice to Tenant after any such claim is made by any
broker.

7.     This confirms that Landlord will continue to hold the security
deposit of $775.00 pursuant to Paragraph Twenty-second of the Lease.

8.     Except as expressly modified by this Addendum, the terms and
conditions of the Lease shall remain in full force and effect, without
change.  This Addendum shall be binding upon, and shall inure to the
benefit of, the parties hereto and their respective successors and
assigns.

IN WITNESS WHEREOF, the parties hereto have caused this Addendum to be
executed by their duly authorized representatives.
