          Equipment subject to this Program.

          Contract Provisions. The Contract [is in the form of Exhibit A hereto,
          -------------------
     has not been modified or amended from such form, and] unconditionally
     provides that:

          1 . The terms of the Contract conform to the terms specified in the
          Contract Summary section of this Restated Supplement;

          respect to the Equipment in an amount not less than the greater of the
          replacement cost of or Investment Balance of such Equipment. The

          Equipment.


                                       3


     3.  Fee Per Scan Information.  Hologic agrees to provide SBCC with meter
         ------------------------
     counts and information upon which billings may be rendered for Fee Per Scan
     Contracts.  Hologic acknowledges that SBCC may rely upon such information
     in billing for and allocating Payments due under Fee Per Scan Contracts.
     SBCC may use whatever means as are available to it to obtain and verify
     such information if not so provided by Hologic, and Hologic will reimburse
     SBCC for all costs and expenses incurred in connection therewith.

     4.  Non-Performing and Terminated Contracts, Repositioning. If a Contract
         --------------------------------------------------------
     becomes a Non-Performing Contract or the Contract is terminated prior to
     its initial scheduled term (but not terminated in connection with a
     prepayment in full or conversion to a Converted Contract) and upon Buyer's
     request or at Seller's option, with Buyer's consent (which will not be
     unreasonably withheld), Seller will "Reposition" the Equipment
                                         ------------
     covered by the Contract by (i) recovering possession of the Equipment and
     (ii) attempting to place such Equipment with a different lessee, user or
     purchaser in the same manner as if the Seller were Remarketing the
     Equipment under paragraph 5 of this Restated Supplement. Upon Seller's
     successful Repositioning of Equipment, any resulting lease or rental
     contract will constitute a replacement for the Contract originally relating
     to the Equipment and any payments under the new contract will be treated
     and applied as Payments with respect to the Equipment (any payments in
     excess of the applicable Attributed Rentals will however, be applied first
     against any future Attributed Rentals for which there is no corresponding
     required payment under the replacement contract). Upon the successful
     Repositioning of any Equipment by sale, the proceeds of such sale will be
     applied in an inverse order of maturity against the unpaid Investment
     Balance for the Equipment.

     5.  Remarketing. The following provisions will apply with respect to
         -------------
     Contracts and Equipment covered by this Restated Supplement:

               (a) Appointment, Priority.  Buyer hereby appoints Seller as its
                   ---------------------
         agent, to Remarket Equipment covered by this Restated Supplement for a
         term commencing with the date of this Restated Supplement and
         continuing until each item of Equipment subject to Remarketing is sold
         to the then Obligor or other end user, and the provisions of this
         Section will apply with respect to the Remarketing of Equipment during
         such term. The terms "Remarket" or "Remarketing" as used herein will
                              ----------    -------------
         mean the re-lease, rental, lease and sale of Equipment as provided in
         this Section 3, on prices, terms and conditions acceptable to Buyer.
         Seller shall use its best efforts to Remarket Equipment. No priority
         is required to be given by Seller to Remarket Equipment owned by
         Buyer, but Seller shall not discriminate against Buyer in favor of any
         new or used equipment or upgrades owned managed or remarketed by
         Seller. Seller will not replace any Equipment owned by Buyer with
         Equipment owned by Seller or any other third party that performs,
         substantially the same functions as Buyer's Equipment (e.g. no "like
         for like" replacements).

          Off-Lease Equipment and with prior notice to Seller, Buyer may arrange
          sales to brokers or dealers. If Buyer arranges a sale of such
          Equipment and notifies Seller before Seller Remarkets such Equipment
          to an end-user, Buyer will be free to conclude such sale. Further, if
          any item of Equipment subject to Remarketing due to the occurrence of

          Buyer may, upon ten (10) days prior written notice, notify Seller of
          Buyer's intention to Remarket such Equipment. If Seller fails to
          Remarket the item within such ten (10) days, Buyer or its designee may
          remarket such item of Equipment on its own behalf. In the event Buyer
          arranges a sale of Equipment to a broker or dealer or undertakes to
          remarket any Equipment, Seller shall only be entitled to receive
          payment of its permitted costs and expenses as provided under Section
          3(h). Seller will not be entitled to any other compensation in
          connection with the Remarketing of such Equipment and all Remarketing
          Proceeds will be for the Buyer's account. Notwithstanding any sale to
          a broker or dealer or any undertaking to remarket by Buyer, Seller
          agrees that it will make available to Buyer and to any lessee,
          purchaser or user of Equipment, at prevailing commercial rates, all
          services, parts, attachments, maintenance and upgrades as it generally
          makes available to owners or users of similar equipment.

               (k) Overseas Transactions. If conversion of the Equipment to a
                   ---------------------
          different model or modification of the Equipment to allow its use in
          any country other than the United States is required in connection
          with any remarketing, Seller will undertake such conversion, with
          Buyer's prior written approval, but the cost thereof will be paid by
          Buyer. Buyer may require that some or all of such Off-Lease Equipment
          be transported by Seller to destinations outside the United States. In
          the event Buyer requests that Equipment be transported outside the
          United States, then Buyer will be responsible for the costs of such
          transportation.

     4.   Application of Remarketing Proceeds: Revenue Sharing. All REMARKETING
          -----------------------------------------------------
     PROCEEDS DERIVED FROM THE REMARKETING OF EQUIPMENT COVERED BY THIS RESTATED
     SUPPLEMENT net of any costs payable to Seller under Section 5(h), will be
     applied in an inverse order of maturity against the unpaid Investment
     Balance for the Equipment.  Provided that Seller continues to Remarket
     Equipment which is subject to this Restated Supplement; after the
     Investment Balance for such Equipment has been reduced to zero, all
     Remarketing Proceeds, and other proceeds received by Buyer from or on
     account of such Equipment and/or related Contracts shall be payable as
     follows and in the following order:

          (a) To the payment of all unpaid sums due and payable to Buyer from
     Seller; then

          (b) 30% to Buyer and 70% to Seller.

                                       8

successors and assigns. Buyer and Seller each acknowledge that the Master
Agreement is in full force and effect and ratify the same. Except as

Supplement.
