apparatus, materials and labor to complete the work in the most substantial and
workmanlike manner according to the Plans and Specifications therefor on file
with the State Engineer and such modifications of the same and other directions
that may be made by the State Engineer as provided herein.

         ARTICLE II - CONTRACT DOCUMENTS: It is further agreed that the
Proposal, Plans, Standard Specifications, Special Provisions, Contract Bond(s)
and any and all Supplementary Agreements, and any and all requirements necessary
to complete the work in a substantial and acceptable manner, and any and all

part of this contract, and shall have the same force and effect as though all of
the same were fully inserted herein.

         ARTICLE III - WARRANTY: The Contractor expressly warrants that he is
free from obligation of any other person or persons for services rendered, or
supposed to have rendered, in the procurement of this contract. He further
agrees that any breach of the Warranty shall constitute adequate cause for the

may retain to its own use from any sums of money due or become due thereunder,
an amount thereof equal to any brokerage, commission, or percentage so paid, or
agreed to be paid.

         ARTICLE IV - TIME OF COMPLETION: The Contractor further covenants and
agrees that all of the said materials shall be furnished and delivered and all

specified time herein. The work shall be free and discharged of all claims and
demands whatsoever for, or on account of any and all labor and materials used or

such case, the Contractor shall become liable for said liquidated damages for
delays commencing from date said extension period shall expire.

writing by the State Engineer. In no event shall the Contractor incur any
liability by reason of any oral direction or instruction that he may be given by

meaning of this Article that all orders, directions, instructions, not contained

         ARTICLE VI - MISUNDERSTANDING OR DECEPTION: The party of the second
part agrees that he has investigated the site of the work and all parts and
appurtenances thereto and hereby waives any right to plead misunderstanding or
deception as to location, character of work or materials, estimates of
quantities or other conditions surrounding or being a part of the work and
understands that the quantities given in the Bidding Schedule are approximate
only, and hereby agrees to accept the quantities as actually placed and finally
determined upon the completion of the work, in accordance with the Contract
Documents.

performance of the work herein embraced, as set forth in the Contract Agreement,
