11.04  Contractor or Company as the case may be shall promptly give to the other
       party notice in writing of any claim made or proceedings commenced for

       under this Contract. Such notice shall state with as much detail as is
       reasonably practicable the facts and circumstances giving rise to the
       claim and shall be given as soon as possible after the party seeking
       indemnity hereunder (referred to in this Section 11.04 as the
       "Indemnitee") becomes aware of such claim or proceeding. The party
       against whom such indemnity is sought (referred to in this Section 11.04
       as the "Indemnitor") shall confer with the Indemnitee concerning the
       defense of any such claim or proceedings but, subject to the remainder of
       this Section 11.04, the Indemnitor or its insurer shall retain control of
       the conduct of such defense, including but not limited to the selection
       and management of counsel. Notwithstanding the foregoing, however,
       neither party shall effect settlement of or compromise any such claim or
       proceedings without having obtained the prior written consent of the
       other party, but if Indemnitee does not consent to a settlement which the
       Indemnitor is willing to accept, then Indemnitor's liability shall be
       limited to the amount for which the lawsuit could have been settled. The
       Indemnitee may, upon written notice to the Indemnitor and at the
       Indemnitee's sole cost and expense, select its own counsel to participate
       in and be present for the defense of any such claim or proceeding,
       provided such counsel shall not take any action in the course of such
       claim or proceeding to prejudice the defense of such claim or proceeding.

11.05  Neither party shall be responsible or held liable to the other for
       indirect, special, incidental or consequential damages, loss of profits
       or loss of use except to the extent such consequential or

                                       5
<PAGE>

       special damages, loss of profits, loss of production, or loss of use are
       part of a Third Party claim for which a party is seeking contribution or
       indemnification pursuant to this contract. Each party shall be granted an
       extension of time for performance of its obligations under this Contract
       if its performance is delayed due to causes beyond its reasonable
       control.

12.01  Insurance.  Contractor shall at all times during the term of this
       Contract maintain, at its sole cost, the following insurance coverage:

     12.01.01  Workers' Compensation Insurance which complies with all

               damage.

       all policies shall name the Company Group as additional insureds. In
       addition, all of the policies listed above, without exception, shall be

       following language: "The insurers hereby waive their rights of
       subrogation against Amoco Production Company, and BP Exploration & Oil
       Inc. ("Company"), and the other entities and persons of the Company Group
       under that certain Contract No. BPA-00-01905 between Company and CiDRA
       Corporation ("Contractor"), and against any individuals, firms, or

       of this Contract to a third party without the prior written approval of
       Company. If Contractor shall cause any part of the Services hereunder to
       be performed by a subcontractor, Contractor shall remain liable for all
       of its obligations hereunder, and in addition shall require in its
       subcontracts that, with respect to the Services to be performed, the
       subcontractor agrees to extend to Company all rights and privileges which
