Buyer will receive a credit at the Closing for all rents payable by Tenants under the Leases as of the Closing and allocable to the period on and after the Closing based upon the actual number of days in the month. No credit shall be given Seller for accrued and unpaid rent or any other non­ current sums due from Tenants until these sums are paid, and Setler shall retain the right to collect any such rent provided Seller does not sue to evict any Tenants or terminate any Leases. Buyer shall cooperate with Seller after the Closing to collect any rent under the Leases which has accrued prior to the Closing; provided, however, Buyer shall not be obligated to sue any Tenants or exercise any legal remedies under the Leases or to incur any expense over and above its own regular collection expenses.

Seller represents and warrants that the schedule of tenant security deposits delivered to Buyer pursuant to the attached Exhibit "G", will be true and correct to Seller's actual knowledge.

7.7.1.5.    CAM Expenses. To the extent that Tenants are reimbursing the landlord under the Leases for common area maintenance and other operating expenses (collectively, "CAM Charges"), CAM Charges shall be prorated at Closing as of the Closing Date on a Lease-by-Lease basis with each party being entitled to receive a portion of the CAM Charges payable under each Lease for the CAM Lease Year (as defined below) in which Closing occurs, which portion shall be equal to the actual CAM Charges incurred during the party's respective periods of ownership of the Property during the CAM Lease Year. As used herein, the term "CAM Lease Year" means the twelve(12) month period as to which annual CAM Charges are owed under each Lease.

If, as of the Closing, Seller has received CAM Charges in excess of the amount that the Tenants will be required to pay, based on the actual CAM Charges as of the Closing, Buyer shall receive a credit against the Purchase Price on the Closing Statement in the amount of such excess. If, as of the Closing, Seller has received CAM Charges that are less than the amount that the Tenants would be required to pay based on the actual CAM Charges as of the Closing, Seller shall be entitled to receive such deficiency when and if such additional payments are made. CAM Charges that are not payable by the Tenants either directly or reimbursable under the Leases shall be prorated between Seller and Buyer and shall be reasonably estimated by the parties if final bills are not available. If final prorations cannot be made at the Closing for any item being prorated, then for any such proration ("Post Closing Proration"), Buyer and Seller agree to allocate such items on a fair and equitable basis as soon as invoices or bills are available and applicable reconciliation with Tenants have been completed, with final adjustment and payment to be made as soon as reasonably possible after the Closing (but in no event later than ninety (90) days after the Closing, except that adjustments arising from any tax protest shall not be subject to such ninety (90) days limitation, but shall be made as soon as reasonably possible), to the effect that income and expenses are received and paid by the parties on an accrual basis with respect to their period of ownership.

7.7.2.    Closing Statement. Prior to the Closing Date, Seller and Escrow Holder shall jointly prepare a closing statement (the"Closing Statement") which shall set forth the costs payable herein and the prorations and credits provided herein and elsewhere in this Agreement. The prorations and credits set forth in the Closing Statement which is signed by each party and delivered at Closing shall be final.

7.7.3.    Items Not Prorated.

Accordingly, there will be no prorations for debt service, insurance or utilities. In the event a meter reading is unavailable for any particular utility, such utility shall be prorated in the manner provided in Section 7.7.1.3 above.

7.7.4.    Indemnification. Buyer and Seller shall each indemnify, protect, defend and hold the other harmless from and against any claim in any way arising from the matters for which the other receives a credit or otherwise assumes responsibility pursuant to this Section 7.7.
