(2) Paragraph (1) of the special condition of the construction contract added pursuant to the instant first amendment agreement (hereinafter “paragraph (1) of the special condition of the construction contract”) is null and void by unfairly restricting the Plaintiff’s contractual interests, and the instant liquidated damages calculated based thereon are unreasonable.
