             whether on the date fixed for payment or by acceleration or
             otherwise; provided, however, that failure to pay any
             principal or interest when due shall not be an Event of
             Default if such overdue payment is paid within ten business
             days of such due date; or

                      (b) if  Borrower or any other authorized person or entity

             winding up of Borrower; or

                      (c) if Borrower shall make a general assignment for
             the benefit of creditors or consent to the appointment of a
             receiver, liquidator, custodian, or similar official of all or
             substantially all of its properties, or any such official is

             commence any action or proceeding or take advantage of or file
             under any federal or state insolvency statute, including,
             without limitation, the United States Bankruptcy Code or any
             political subdivision thereof, seeking to have an order for

             bankrupt or insolvent, or seeking reorganization, arrangement,
             adjustment, liquidation, dissolution,

                      (d) there shall be commenced against Borrower any
             action or proceeding of the nature referred to in paragraph
             (c) above or seeking issuance of a warrant of attachment,
             execution, distraint, or similar process against all or any
             substantial part of the property of Borrower, which results in
             the entry of an order for relief which remains undismissed,
             undischarged or unbonded for a period of sixty days; or

                      (e) Borrower enters into an agreement to acquire a
             business other than SpaceLogix without the consent of SpaceLogix."

delivered hereunder shall be governed by and construed in accordance with the
