                      ADDENDUM NO. 1 TO SUBLEASE AGREEMENT

This Addendum No. 1 (the "Addendum") dated as of September 1, 2003, is made and
entered into by and between TriPath Imaging, Inc., a Delaware corporation (as
the Successor in interest to AutoCyte, Inc., as the Successor in interest to
Neopath, Inc.) ("Sublandlord") and Antioch Bible Church ("Subtenant") with
reference to the Sublease Agreement (the "Sublease") dated August 31, 1999
originally entered into between Sublandlord and Subtenant. All terms defined in
the Sublease shall have the same meanings when used in this Addendum with
initial letters capitalized.

WHEREAS, Subtenant is in arrears to Sublandlord for about 3 months' Rent under
the Sublease and desires some additional time to pay Sublandlord the amount in
arrears; and

WHEREAS, Sublandlord is willing to grant Subtenant additional time to pay the
amount in arrears provided that certain terms and conditions are met.

NOW THEREFORE, in consideration of the mutual covenants herein contained, the
Sublandlord and Subtenant hereby agree as follows:

1.       Section 1 of the Sublease shall be amended as follows: Add the
         following text as the second sentence: "Sublandlord shall have the
         right at any time during the Term to utilize between 3,000 and 5,000
         square feet of the warehouse portion of the Premises for the
         Sublandlord's own use at no cost to Sublandlord, subject to a mutually
         agreed upon plan for access and security."

2.       Section 4.2 (a) of the Sublease shall be amended as follows:
         Period:                                 Base Monthly Rent:

         October 1, 1999 - December 31, 2002     $28,000.00
         January 1, 2003 - August 31, 2003       $28,000.00 plus Consumer Price
                                                 Increase
         September 1, 2003 - December 31, 2004   $25,000.00*

         * The Base Monthly Rent shall include the Operating Expenses as defined
         in Section 5 of the Sublease and further defined in Section 4 of the
         Master Lease.

3.       Subtenant acknowledges and agrees that it owes Sublandlord $107,044 for
         past due Rent through August 31, 2003 under the Sublease. In
         consideration of Sublandlord agreeing not to bring an action against
         Subtenant for failure to pay the Rent in accordance with the terms of
         the Sublease, Subtenant agrees to pay Sublandlord $7,136.27 per month
         starting September 1, 2003 through December 31, 2004 with payments to
         be made in accordance with Section 4.1 of the Sublease. Notwithstanding
         the foregoing, in the event that Subtenant defaults on 4 monthly past
         due Rent payments, Subtenant shall pay Sublandlord immediately on
         demand the amount of all past due Rent and other losses and damages
         which Landlord may suffer as a result of Subtenant's default.

The Sublease, as amended by this Addendum, shall remain in full force and effect
in accordance with its terms. The Sublease is and shall be at all times subject
to and subordinate to the Master Lease.

IN WITNESS WHEREOF, the parties have hereunto set their hands and seals the day
and year first above written.
