If the Owner, the Contractor and the Surety agree, the Contractor shall be allowed a reasonable time to perform the Construction Contract, but such an agreement shall not waive the Own- er's right, if any, subsequently to declare a Contractor Default; and 3.2 The Owner has declared a Contractor Default and for- mally terminated the Contractor's right to complete the contract. Such Contractor Default shall not be declared earlier than twenty days after the Contractor and the Sur- ety have received notice as provided in Subparagr<!-ph 3.1; and 3.3 The Owner has agreed to pay the Balance of the Contract Price to the Surety in accordance with the terms of the Construction Contract or to a contractor selected to per- form the Construction Contract in accordance with the terms of the contract with the Owner. 4 When the Owner has satisfied the conditions of Paragraph 3, the Surety shall promptly and at the Surety's expense take one of the following actions: 4.1 Arrange for the Contractor, with consent of the Owner, to perform and complete the Construction Contract; or 4.2 Undertake to perform and complete the Construction Contract itself, through its agents or through independent contractors; or 4.3 Obtain bids or negotiated proposals from qualified con- tractors acceptable to the Owner for a contract for per- formance and completion of the Construction Contract, arrange for a contract to be prepared for execution by the Owner and the contractor selected with the Owner's con- currence, to be secured with performance and payment bonds executed by a qualified surety equivalent to the - bonds issued on the Construction Contract, and pay to the Owner the amount of damages as described-in Para- graph 6 in excess of the Balance of the Contract Price incurred by the Owner resulting from the Contractor's I default; or 4.4 ' Waive its right to perform and complete, arrange for com- pletion, or obtain a new contractor and with reasonable promptness under the circumstances: .1 After investigatio{l, determine the amount for which it may be liable to the Owner and, as soon as practicable after the amount is determined, tender payment therefor to the Owner; or .2 Deny liability in whole or in part and notify the Owner citing reasons therefor. 5 If the Surety does not proceed as provided in Paragraph 4 with reasonable promptness, the Surety shall be deemed to be in default on this Bond fifteen days after receipt of an additional written notice from the Owner to the Surety demanding that the Surety perform its obligations under this Bond, and the Owner shall be entitled to enforce any remedy available to the Owner.
