                                            or indirect legal liability of MedImmune arising out of the

                                    (CONFIDENTIAL TREATMENT REQUESTED).

                                    accordance with requirements which shall be specified by the Contractor in
                                    Subcontractor agreements approved by MedImmune.  The Contractor shall
                                    indemnify MedImmune for any loss suffered by it for the Contractor's failure
                                    to require a Subcontractor to be so insured.

                           .6       Certificates of Insurance acceptable to MedImmune shall be filed with
                                    MedImmune prior to the commencement of the Work.  These Certificates shall
                                    contain a provision that coverages afforded under the policies will not be
                                    cancelled or modified until at least thirty days prior written notice has been
                                    given to MedImmune.  The compliance by the Contractor with insurance
                                    requirements in Sections 11.1 and 11.3 shall not relieve the Contractor from
                                    liability under the indemnification provisions of Section 3.18.  If any of the
                                    foregoing insurance coverages are required to remain in force after final
                                    payment and are reasonably available, an additional certificate evidencing
                                    continuation of such coverage shall be submitted with the final Application
                                    for Payment as required by Subparagraph 9.10.2

                           11.4.1.3  If the property insurance requires minimum deductibles and such deductibles
                                     are identified in this Contract, the Contractor shall pay losses, damages,
                                     costs, etc. not covered because of such deductibles.  If the Owner or
                                     insurer increases the required minimum deductibles above amounts so
                                     identified or if the Owner elects to purchase this insurance with higher
                                     minimum deductible amounts, the Owner shall be responsible for payment of
                                     the additional losses, damages, costs, etc. not covered because of such
                                     increased or voluntary deductibles.  The minimum deductible requirement of
                                     this contract shall be set at (CONFIDENTIAL TREATMENT REQUESTED).

                           11.4.11  Assistance and Cooperation

                                    The Contractor agrees to assist and cooperate in every possible manner in
                                    connection with the adjustment of all claims arising out of Work provided for
                                    under the contract and to cooperate with any insurance carrier in all claims
                                    and demands arising out of such operations which the insurance carrier is
                                    called upon to adjust.

                           11.4.12  Additionals or Alternations to Insurance

                                    The Contractor has the right to maintain at its own expense any additional
                                    kinds of insurance or to increase limits above those set forth in  this
                                    Article.  If so requested by MedImmune, Contractor shall alter the kinds of
                                    its insurance and/or increase the limits thereof, and any such change shall be
                                    at the expense of MedImmune, but only to the extent that such expense is
                                    applicable to the Contract.

At no time shall the recovery exceed the stipulated sum.

If the financial condition of the Contractor becomes unsatisfactory to MedImmune, or if the Contractor persistently or repeatedly
refuses or fails, except in cases for which extension of time is provided, to supply enough properly skilled workers or proper
materials, or if it fails to make prompt payment to Subcontractors for materials or labor, or persistently disregards laws,
ordinances, rules, regulations or orders of any public authority having jurisdiction, or otherwise is guilty of a substantial
violation of a provision of the Contract Documents, then MedImmune, upon certification by the Engineer that sufficient cause exists
to justify such action, may, without prejudice to any right or remedy and after giving the Contractor and its surety, if any, seven
(7) days' written notice, terminate the employment of the Contractor and take possession of the site and may finish the Work by
whatever method it may deem expedient. In such case, the Contractor shall not be entitled to receive any further payment until the
Work is finished.

34. Article 15 - Add the following as Article 15:
In connection with the Work that the Contractor will undertake under this Contract, it can be expected that certain secret and
confidential information will be furnished or made available to the Contractor by MedImmune, or will be developed by the Contractor
for MedImmune. Such information shall be treated by the Contractor as confidential and used solely in connection with the Work the
Contractor is to perform. The Contractor shall not use it for its own benefit and shall use all reasonable precautions to retain it
in confidence and prevent its disclosure to others.

Such information shall not be disclosed to anyone other than the Contractor's employees, subcontractors, or agents who need such
information to be able to perform the Work to be done under this Contract.

To insure that this responsibility is met, the Contractor shall instruct all persons who engage in work under this Contract,
including but not limited to subcontractors, that they shall keep such information confidential regardless of whether their
relationship with the Contractor is terminated at some future time and, if MedImmune so requests, the Contractor agrees to have such
persons (including, but not limited to subcontractors) who engage in work under this Contract execute agreements in a form
acceptable to MedImmune to insure that such confidentiality is maintained.

The above restrictions shall not apply to any information which the Contractor can demonstrate was (a) part of the public knowledge
or literature, or already known to the Contractor on the date it was disclosed to the Contractor by MedImmune, or (b) subsequent to
the time of disclosure became part of the public knowledge or literature through no fault of the Contractor, or was rightfully
disclosed to the Contractor by a third party.
