[The provisions of this Article supersede all of Article 37 of the General Conditions of the Contract except the first sentence.]

If the Owner should terminate the contract under the first sentence of Article 37 of the General Conditions of the Contract, he shall reimburse the Contractor for the balance of all payments made by him under Article 5, plus a fee computed upon the cost of the work to date at the rate of percentage named in Article 4 hereof, or if the Contractor's fee be stated as a fixed sum, the Owner shall pay the Contractor, such an amount as will increase the payments on account of his fee to a sum which bears the same ratio to the said fixed sum as the cost of the work at the time of termination bears to a reasonable estimated cost of the work completed, and the Owner shall also pay to the Contractor fair compensation, either by purchase or rental, at the election of the Owner, for any equipment retained. In case of such termination of the contract the Owner shall further assume and become liable for all obligations, commitments and unliquidated claims that the Contractor may have theretofore, in good faith, undertaken or incurred in connection with said work and the Contractor shall, as a condition of receiving the payments mentioned in this Article, execute and deliver all such' papers and take all such steps, including the legal assignment of his contractual rights, as the Owner may require for the purpose of fully vesting in him the rights and benefits of the Contractor under such obligations or commitments.

The Contractor and the Owner for themselves, their successors, executors, administrators and assigns hereby agree to the full performance of the covenants herein contained.

In witness whereof, they have executed this agreement the day and year first above written.
