(z) the Security Agent (such two loan agreements being hereinafter sometimes
together called the "LOAN AGREEMENTS") and (2) all other documentation referred
to in the Loan Agreements.

WHEREAS:

A.    The Additional Funding and Guarantee Agreement included certain provisions
      to the following effect:

      (1)   Each Sponsor gave an undertaking to MC1 and MC2 that, on or prior to
            the Bridging Loan Repayment Date, it would, in its Several
            Proportion, make Sponsors' Funds available to the Borrowers in the
            aggregate principal amount of US$100,000,000 (comprising
            US$47,000,000 to be made available to Petrodrill Six and
            US$53,000,000 to be made available to Petrodrill Seven).

      (2)   Each Sponsor severally guaranteed to MC1 the due and punctual
            payment by MC2 of such Sponsor's Several Proportion of the Bridging
            Loans (in all respects in accordance with the Bridging Loan
            Agreement) and the payment of all interest in respect thereof
            (including interest capitalized in accordance with the terms
            thereof).

      (3)   MC2 gave each of the Sponsors an option (exercisable on the terms
            and in the manner, and subject to the conditions, specified in the
            Additional Funding and Guarantee Agreement) to require MC2 to
            transfer to each Sponsor such Sponsor's

            Several Proportion of the whole (but, save as provided in the
            Additional Funding and Guarantee Agreement, not part only) of the
            MC2 Participations.

      (4)   MC2 gave an undertaking to the Sponsors that any amounts received
            and retained by MC2 from the Sponsors in respect of the exercise of
            such options would be applied pro tanto in or towards repayment to
            MC1 of the Bridging Loans.

B.    Instead of arranging for a transfer to the Sponsors of the whole of the
      MC2 Participations (as envisaged by Clause 3 of the Additional Funding and
      Guarantee Agreement), the Sponsors have made arrangements for the whole of
      the MC2 Participations to be transferred to Amethyst with effect from 1
      November 1999 in consideration of the payment by Amethyst to MC2 of the
      Transfer Price.

NOW IT IS HEREBY AGREED as follows:

      (2)   notwithstanding Clause 15.3 of the Loan Agreements, the Trustee, the
            Collateral Agent or any other beneficiary under a Security Document

            Clause 15.4 of the relevant Loan Agreement, except to the extent
            modified by this Deed to, among other things, eliminate the strict
            requirement that the transferee be a Qualifying Lender, so that

            with a principal place of business in any country which is a member
            of OECD managing or owning a minimum of $100 million in assets

            Trustee, the Collateral Agent and any other beneficiary under the
            Security Documents shall not have any obligation or duty to MC1,

            the Trustee directly shall be entitled to exercise any and all
            voting and other consensual rights of Amethyst pertaining to the MC2
            Participations and the Mitsubishi Documents.
