      satisfy such conditions upon request from the Lenders forthwith or within
      such time limit as the Facility Agent may agree.

4.    DISBURSEMENT OF ADVANCES

4.1   GENERAL

      Subject to the terms of this Agreement (including, but not limited to, the
      conditions set forth in Clause 3):

      (i)   subject to sub-paragraph (ii) of this Clause 4.1, Advances
            under the Tranche A Facility, the Tranche B Facility and the Tranche
            C Facility may be drawn by the Borrower in a maximum principal
            amount up to but not exceeding the Available Facility Amount of the
            relevant Facility on the Drawdown Date of the relevant Advance when
            requested by the Borrower from time to time during the Availability
            Period; and

      (ii)  with effect from the Tranche C Availability Commencement Date
            Advances shall be made under each of the Facilities in the
            proportions PRO RATA which the Available Facility Amount of each
            such Facility bears to the Total Available Facility Amounts of all
            the Facilities on the Drawdown Date of such Advances.

4.2   PROCEDURE

      When the Borrower wishes to draw any Advance under any of the Facilities,
      it shall deliver to the Facility Agent a Drawing Request substantially in
      the form of Schedule 4 appropriately completed, to be received by the
      Lender not later than 11:00am (London time), seven (7) Banking Days prior
      to the date of drawing of the Advance, specifying in respect of the
      proposed Drawing:

      (a)   the date of the Drawing  (which must be a Banking Day during
            the Availability Period);

      (b)   the principal amount of the Advance in US Dollars; and

      (c) the Facility under which the Drawing is requested.

      The Borrower may deliver a Drawing Request setting out a schedule of
      requested Pre-delivery Advances subject to the satisfaction of the
      conditions specified in this Agreement on the Drawdown Date of such
      Advances and, in particular, Clause 3.2. Subject to the terms of this
      Agreement, such Drawing Request shall be irrevocable and the Borrower
      shall be bound to borrow in accordance with such Drawing Request. The
      Facility Agent shall promptly notify each Lender of such Drawing Request.
      The Borrower may not deliver a Drawing Request hereunder until after
      satisfaction of the other conditions precedent (including those applicable
      to the relevant Facility) set out in Clause 3.

                                     - 24 -

4.3   TRANSFER OF FUNDS

      Subject as otherwise provided herein each Lender shall on the relevant
      Drawdown Date make available to the Facility Agent in US Dollars in the
      manner and to the account provided for in Clause 9.2 the amount of its
      participation in the relevant Advance in the proportion which its
      Commitment in respect of the Facility under which such Advance is drawn
      bears to the Total Commitments in respect of such Facility. The Borrower
      irrevocably and unconditionally instructs and authorises the Facility
      Agent to make each Advance upon and subject to the terms hereof:

      (i)   in the case of an Advance made or to be made for the purpose
            specified in Clause 2.2(i) by paying the proceeds thereof (or such
            proportion thereof as is not in reimbursement of amounts already
            paid by the Borrower) by disbursement to the Builder;

      (ii)  in the case of an Advance made or to be made for the purpose
            specified in Clause 2.2(ii) by disbursement to the Sister Company in
            accordance with the Inter-Company Loan Agreement;

      (iii) in the case of an Advance made or to be made for the purposes
            specified in Clause 2.2(iii), 2.2(iv), 2.2(v), 2.2(vi) or 2.2(vii)
            by disbursement to the Borrower of amounts paid or payable by the
            Borrower in respect of the matters specified in such sub-clauses

      and upon such disbursement of any amount the Lenders shall be deemed in
      proportion to the respective amounts made available by them to the
      Facility Agent to have made to the Borrower an Advance in US Dollars in
      the amount of the amount so disbursed which shall satisfy PRO TANTO the
      obligations of such Lenders to lend such amount to the Borrower hereunder
      and shall reduce accordingly the amount of the Commitments and of such
      Facility available for drawing.

4.4   CAPITALISATION OF INTEREST

      Subject as provided in Clause 5.2(ii) on each Interest Capitalisation Date
      the Borrower shall be deemed to have served a Drawing Request requesting
      an Advance (an "INTEREST CAPITALISATION ADVANCE") in respect of each
      Advance outstanding on such Interest Capitalisation Date in the amount of
      interest to be capitalised on such outstanding Advance on such Interest
      Capitalisation Date in accordance with Clause 5.2. Each Interest
      Capitalisation Advance shall be deemed to have been requested from those
      Lenders who have participated in the Advances (or to whom participations
      in such Advances have been transferred in accordance with the Transfer
      Certificates pursuant to which they become Lenders hereunder) to which it
      relates (and shall be deemed to be drawn under the Facility or Facilities
      under which such Advances were drawn) and (subject to Clause 4.5) such
      Lenders shall be deemed to have made to the Borrower an Interest
      Capitalisation Advance in US Dollars in the amount of such interest which
      shall (i) increase the amount of the Loan by such amount; (ii) satisfy PRO
      TANTO the obligations of such Lenders PRO RATA in proportion to their
      respective participations in such Advance to lend such amount to the
      Borrower hereunder; and (iii) reduce accordingly the amount of their
      Commitments and of such Facility available for drawing. The Facility Agent

                                     - 25 -

      shall calculate, and notify the relevant Lenders and the Borrower of the
      amount of each Interest Capitalisation Advance and of such Lenders'
      respective participations therein.

4.5   FACILITY LIMIT

      Interest on the Advances will not be capitalised if this would cause the
      amount of the Loan to exceed the Total Facilities Amount. Accordingly, if
      on any Interest Capitalisation Date as a result of the application of
      Clause 4.4 and of Clause 5.2 the aggregate amount of all Advances exceeds
      (or, if an Interest Capitalisation Advance were made or deemed to be made
      pursuant to Clause 4.4 the aggregate of all Advances would exceed) the
      Total Facilities Amount the Borrower shall pay to the Facility Agent for
      the account of the Lenders by way of a payment of interest the amount of
      interest which would otherwise have been capitalised by means of such
      Interest Capitalisation Advance.

4.6   CANCELLATION

      Any portion of the Total Commitments in respect of any Facility not
      advanced hereunder on or prior to the last day of the Availability Period
      shall be reduced automatically to nil immediately thereafter and shall not
      thereafter be available for drawing.

4.7   FAILURE TO DRAW

      If for any reason (other than a default by a Lender or a Lender's bank)
      the Advance is not made hereunder after a Drawing Request therefor has
      been given pursuant to Clause 4.2, the Borrower will pay to the Facility
      Agent for the account of the relevant Lenders such amount as the Facility
      Agent may certify in reasonable detail (such certification to be
      conclusive in the absence of manifest error) as necessary to compensate it
      for any resulting loss or expense on account of funds acquired, contracted
      for or utilised in order to fund the Advance.

5.    INTEREST

5.1   RATE

      Interest shall accrue on the Loan from the respective Drawdown Dates of
      each Advance comprising the Loan until actual repayment (i) in respect of
      the period prior to the Yard Delivery Date at the rate of 12.5% per annum
      and (ii) thereafter, at the rate of 11% per annum.

5.2   CAPITALISATION AND PAYMENT OF INTEREST

      (i)   Subject to paragraph (i) below interest accruing prior to the
            Charterparty Commencement Date shall be capitalised in accordance
            with this Clause and the other provisions of this Agreement. On each
            Interest Capitalisation Date interest which has accrued on the Loan
            shall be capitalised and added to the amount of the Loan in
            accordance with Clause 4.4 so that the principal amount of the Loan
            shall thereafter be deemed for all purposes (including, but not
            limited to, the calculation of interest) to comprise and to include
            the principal amount advanced hereunder and the amount of such
            capitalised interest deemed to have been advanced.

                                     - 26 -

      (ii)  Interest accruing on all Tranche A Advances during the period from
            the Bridging Loan Repayment Date until the Charterparty Commencement
            Date shall not be capitalised but shall be paid in arrears on each
            Interest Capitalisation Date.

5.3   DEFAULT RATE

      Without affecting any other remedy of the Lenders or the Agents hereunder,
      the Borrower will pay interest on the Loan or any part thereof or interest
      thereon or other sum due under this Agreement or any of the Security
      Documents which is not paid on the due date for payment thereof for each
      day during the period of such default at such annual rate as is
      conclusively certified by the Facility Agent to the Borrower to be equal
      to the aggregate of (1) two per cent (2%) per annum and (2) the higher of
      (a) the rate quoted by the Facility Agent as the arithmetic mean quoted by
      the Lenders (or, in the absence of such quotation from any Lender
      determined by the Facility Agent) (weighted by reference to the
      participations of the Lenders in the overdue payment in question) as being
      the rates at which each such Lender was (or would have been), at or about
      11.00am (London time) on the date of acquisition of the relevant deposits,
      able in accordance with its usual practices to fund in US Dollars from its
      principal bankers on an overnight or call basis or for such period or
      periods as such Lender may determine and in amounts equivalent to, or
      comparable with, the amount of the Loan or relevant part thereof or
      interest thereon or other sum due in respect thereof as aforesaid in
      respect of which default has been made and (b) 11%. Interest payable by
      the Borrower as aforesaid shall be payable on demand by the Facility Agent
      and shall be compounded at such intervals as the Facility Agent may
      determine.

5.4   DAY COUNT FRACTION

      All interest is respect of Advances and the Loan shall accrue from day to
      day (after as well as before judgment) on the basis of a year of 360 days
      and for the actual number of days elapsed.

6.    REPAYMENT AND PREPAYMENT

6.1   CONSOLIDATION OF ADVANCES

      In addition and without prejudice to any other provision of this
      Agreement, with effect from the Charterparty Commencement Date all
      Advances drawn under the Facilities and then comprising the Loan shall be
      consolidated and treated as a single amount for all purposes of this
      Agreement.

6.2   REPAYMENT INSTALMENTS

      The Borrower shall repay an amount equal to 85% of the Loan outstanding on
      the Charterparty Commencement Date after the capitalisation of interest on
      such date in accordance with Clause 5.2 together with the interest
      accruing on the Loan during the period of such repayments by means of
      eighty-four (84) equal payments, one such payment being payable on each
      Repayment Date in the amount of the Repayment Instalment (comprising a
      proportion of the principal of the Loan repayable on each such date and
      the interest element payable on each such date) specified in respect of
      such Repayment Date in the Repayment Schedule delivered by the Facility
      Agent pursuant to Clause 6.4. The Repayment Dates shall be the fifth day
      of the second month next

                                     - 27 -

      and the 83 dates falling at consecutive monthly intervals thereafter.

6.3   BALLOON PAYMENT

      The remaining 15% of the Loan outstanding on the Charterparty Commencement
      Date as aforesaid shall be repaid by a single payment on the Final
      Repayment Date.

6.4   REPAYMENT SCHEDULE

      The Facility Agent shall prepare, within fourteen (14) Banking Days after
      the Charterparty Commencement Date, a repayment schedule in the form of
      the Repayment Schedule set out in Schedule 2 setting forth the specific
      Repayment Dates and the specific amounts of each Repayment Instalment,
      comprising a proportion of the principal of the Loan repayable on each
      such date and the interest element payable on each such date, which shall
      form an integral part hereof upon notification thereof to the Borrower.

6.5   REBORROWING

      No amount repaid may be reborrowed by the Borrower.

6.6   PREPAYMENT

      The Borrower may upon giving the Facility Agent not less than 90 days'
      prior written notice prepay the whole or part of the Loan subject to and
      in accordance with Clauses 6.8 and 18. Save as expressly permitted or
      required under the terms of this Agreement the Borrower may not prepay any
      part of the Loan.

6.7   TOTAL LOSS OF THE RIG

      In the event that the Rig becomes a Total Loss at any time, the whole of
      the insurance proceeds or other compensation payable in respect of such
      Total Loss will be paid to the Security Agent (as assignee(s) and chargee
      thereof under the Rig Construction Contract and Refund Guarantee
      Assignment, the Rig Mortgage and associated Deed of Covenants, the
      Mortgage Debenture and the Insurances Assignment). In the event that any
      of the said insurance proceeds or other compensation are received in any
      currency other than US Dollars, the Facility Agent on behalf of the
      Lenders will be entitled (and is hereby authorised) at the cost of the
      Borrower to convert the same into US Dollars at the Facility Agent's
      principal banker's spot rate of exchange applicable at the relevant time.
      The whole amount of such insurance proceeds or other compensation
      (converted into US Dollars, if appropriate) will be applied by the
      Facility Agent in or towards prepayment of the Loan subject to and in
      accordance with Clauses 6.8 and 18 and any excess shall be paid to the
      Borrower. If the amount thereof is less than the Outstanding Indebtedness
      the Borrower shall on demand pay to the Facility Agent for the account of
      the Lenders the amount of such shortfall.

6.8   CONDITIONS APPLICABLE

      Prepayment of the Loan made under Clauses 6.6 or 6.7 will be made together
      with accrued interest to the date of prepayment together with all other
      amounts which may be payable under this Agreement and the other Security
      Documents. On any such

                                     - 28 -

      prepayment the Borrower will additionally pay such further amount as will
      indemnify the Agents and the Lenders against all funding or other fees,
      costs, charges, losses, demands and expenses sustained or incurred as a
      consequence of such prepayment, including (but not limited to) any such
      sustained or incurred in liquidating deposits taken to fund the amount so
      prepaid or sustained or incurred in connection with the cancellation,
      reduction or re-arrangement of any interest rate swap, hedge transaction
      or other funding or financing agreement or arrangement which the Agents
      and/or any of the Lenders may have arranged or entered into for the
      purpose of funding the amount so prepaid (and the Borrower hereby
      acknowledges that the Agents and the Lenders may effect such arrangements
      as the Agents and/or any of the Lenders may in their discretion consider
      appropriate), and the certificate of the relevant Agent or Lender as to
      the amount of such fees, costs, charges, losses, demands, expenses and
      shall in the absence of manifest error be final and conclusive and binding
      on the Borrower.

      provision of this Agreement shall (subject always to any appropriation by

            the Existing Lender;

      (iii) the rights of the Existing Lender against the existing Parties and
            vice versa (the "DISCHARGED RIGHTS") will be cancelled; and

      supplied by it or on its behalf in connection with any Security Document,
      each Lender confirms that it has itself been, and will at all times
      continue to be, solely responsible for making its own independent
      investigation and appraisal of the business, financial condition,
      prospects, creditworthiness, status and affairs of the Borrower, the
      Guarantors or any other person

                                     - 58 -

      and has not relied, and will not at any time rely, on the Facility Agent
      or any other Lender:-

      (i)   to provide it with any information relating to the business,
            financial condition, prospects, creditworthiness, status or affairs
            of the Borrower, the Guarantors or any other person, whether coming
            into its possession before or after the drawing of the Facility
            (except as stated in Clause 19.2 or as provided otherwise in this
            Agreement); or

      (ii)  to check or enquire into the adequacy, accuracy, completeness or
            reasonableness of any representation, warranty, valuation,
            statement, projection, assumption or information at any time
            provided by or on behalf of the Borrower, the Guarantors or any
            other person under or in connection with any Security Document
            (whether or not that information has been or is at any time
            circulated to it by the Facility Agent); or

      (iii) to assess or keep under review the business, financial condition,
            prospects, creditworthiness, status or affairs of the Borrower, the
            Guarantors or any other person.

19.8  LENDERS' INDEMNITY

      To the extent that the Borrower or either of the Guarantors do not do so
      on demand or are not obliged to do so, each Lender shall on demand
      indemnify the Facility Agent in the proportion borne by its Outstandings
      to all the Outstandings at the relevant time (or, if there are then no
      Outstandings, in the proportion borne by its Commitments to the Total
      Commitments) against any cost, expense or liability mentioned in Clause 16
      (Fees and Expenses) or sustained or incurred by the Facility Agent in
      complying with any instructions from the Majority Lenders or otherwise
      sustained or incurred by it (in its capacity as an Agent) in connection
      with its duties, obligations and responsibilities under the Security
      Documents except routine administrative costs and expenses of the Facility
      Agent or to the extent that they are sustained or incurred as a result of
      the gross negligence or wilful misconduct of the Facility Agent or any of
      its personnel or agents.

19.9  CHANGE OF AGENTS

      Notwithstanding the irrevocable appointments in Clause 19.1, the Facility
      Agent may resign at any time if it gives at least 30 days' notice in
      writing to the Borrower and the Lenders and the Facility Agent may at any
      time be removed by the Majority Lenders giving not less than 30 days'
      notice to the Facility Agent. However, no resignation or removal shall be
      effective until the successor has been appointed and accepted its
      appointment in accordance with this Clause 19.9. The Majority Lenders may
      appoint a successor to the resigning or removed Facility Agent but, if the
      successor has not been so appointed and accepted its appointment within 15
      days after the date of the notice of resignation or, as the case may be,
      removal, the resigning Facility Agent and the Majority Lenders may appoint
      a successor Facility Agent. Any appointment of a successor must be in
      writing, signed by the person(s) appointing that successor and delivered
      to that successor. Any acceptance of such appointment must be in writing,
      signed by the person appointed and delivered to the person(s) appointing
      that successor. The other parties to this Agreement shall be promptly
      informed of the acceptance by a successor Facility Agent. Upon the
      successor accepting its appointment, the resigning or, as the case may

                                     - 59 -

      be, the removed facility Agent shall be automatically discharged from any
      further obligation under the Security Documents and its successor and each
      of the other parties to the Security Documents shall have the same rights
      and obligations among themselves as they would have had if the successor
      had been the original Facility Agent party to this Agreement and the other
      Security Documents. The resigning or, as the case may be, the removed
      Facility Agent shall provide its successor with (or with copies of) such
      records as its successor requires to carry out its duties under the
      Security Documents.

19.10 SIGNING OF TRANSFER CERTIFICATES

      The Borrower, the Security Agent and each Lender (except for the Existing
      Lender and the New Lender seeking the relevant assignment and/or novation)
      irrevocably authorises the Facility Agent to sign each Transfer
      Certificate on their behalf.

19.11 ACCEPTANCE OF TITLE

      The Facility Agent may accept without investigation, requisition or
      objection such title as any person may have to the undertakings, property
      and assets which are subject to the Security Documents and shall not be
      bound or concerned to examine or enquire into nor be liable to any other
      Secured Party or any other person for any defect or failure in the title
      of any person whether such defect or failure was known to the Facility
      Agent or might have been discovered upon examination or enquiry and
      whether capable of remedy or not nor for any failure on the part of the
      Facility Agent to give notice to any third party of the Security Documents
      to which it is party or otherwise perfect or register the security thereby
      created.

19.12 THE BORROWER AND THE FACILITY AGENT

      The Borrower shall be entitled to rely on any direction, instruction,
      certificate, document or other communication made by the Facility Agent
      and shall not be required to enquire whether it is made with the authority
      of the Lenders, and performance of any obligation arising under this
      Agreement or the Security Documents in reliance on any such shall be
      deemed to be proper performance of the obligation in question.

19.13 AGENT OF THE LENDERS

      Save as expressly provided in the Security Documents, the Facility Agent
      is appointed hereunder and thereunder solely as the agent of the Lenders,
      and the foregoing provisions of this Clause 19 (The Agents) apply solely
      to the Facility Agent in their capacity as agent for the Lenders.

19.14 AGENT'S KNOWLEDGE

      Information obtained by the Facility Agent in any capacity other than in
      its capacity as Facility Agent and or through any department other than
      the department having specific responsibility for the administration of
      the Loan and the Security Documents shall not be imputed to the Facility
      Agent.

                                     - 60 -

19.15 AMENDMENTS

      The Facility Agent may (except where any other authority is required for
      the same by the express provisions of the Financing Documents) grant
      waivers or consents or vary the terms of the Financing Documents only if
      the same has been authorised by the Majority Lenders. Any such waiver,
      consent or variation so authorised and effected by the Facility Agent
      shall be binding on all the Lenders and the Facility Agent shall be under
      no liability whatsoever in respect of any such wavier, consent or
      variation. This Clause 19.15 shall not authorise, except with the prior
      consent of all the Lenders:

      (a)   any change in the manner in which interest is calculated or paid
            under this Agreement in respect of the Loan;

      (b)   any extension of the date for, or alteration in the amount or
            currency of, any payment of principal, interest, fee, commission or
            any other amount payable under the Financing Documents in respect of
            the Loan;

      (c)   any increase in any Lender's Commitment in respect of the
            Facilities;

      (d)   any extension of a date on which a payment of principal must be paid
            in respect of the Loan; or

      (e)   any variation of the definition of Majority Lenders, and this Clause
            19.15 shall not authorise, except with the prior consent of all the
            Lenders;

      (g)   any variation of:

            (i)   Clause 14.1 (ILLEGALITY), 20.2 (PRO RATA SHARING); or

            (ii)  this Clause 19.17,

      (h)   any extension of the Availability Period; or

      (i)   any amendment of any provision of the Financing Documents which
            contemplates the need for the consent or approval of each Lender.

19.16 THE SECURITY AGENT

      The Lenders will appoint the Security Agent to act as security agent in
      accordance with the Security Trust Deed.

20.   SET-OFF/PRO-RATA SHARING

20.1  SET OFF

      The Borrower authorises the Facility Agent and each of the Lenders to
      apply (without prior notice) any credit balance (whether or not then due)
      to which the Borrower is at any time beneficially entitled on any account
      at, any sum held to its order by and/or any liability or obligation
      (whether or not matured) of, any office of the Facility Agent or such
      Lender in or towards satisfaction of any sum then due and payable by it to
      the Facility Agent or such Lender under the Security Documents and unpaid
      and, for that

                                     - 61 -

      purpose, to convert one currency into another (provided that nothing in
      this Clause 20.1 shall be effective to create a charge, and provided
      further that any credit balance, sum and/or liability or obligation as
      aforesaid shall be held by the Facility Agent or, as the case may be, such
      Lender pursuant to or in connection with the Security Documents). No party
      shall be obliged to exercise any of its rights under this Clause 20.1,
      which shall be without prejudice and in addition to any right of set-off,
      combination of accounts, lien or other right (including the benefit of the
      Security Documents) to which it is at any time otherwise entitled (whether
      by operation of law, contract or otherwise). Each Lender shall notify the
      Facility Agent and the Borrower forthwith upon the exercise or purported
      exercise of any right of set-off giving full details in relation thereto
      and the Facility Agent shall inform the other Lenders forthwith.

20.2  PRO-RATA SHARING

      If at any time the proportion received or recovered (whether by direct
      payment, by exercise of any right of set-off, combination of accounts or
      lien, or otherwise) by any Lender in respect of the total sum which has
      become due to it from the Borrower or either of the Guarantors under the
      Security Documents before that time exceeds the proportion received or
      recovered by the Lender(s) receiving or recovering the smallest proportion
      (if any), then:-

      (i)   such Lender shall promptly notify the Facility Agent and within 2
            Banking Days after receiving a request from the Facility Agent, that
            Lender shall pay to the Facility Agent an amount equal to the excess
            and the Facility Agent shall notify the Borrower or the relevant
            Guarantor, as the case may be, of the receipt of such amount;

      (ii)  the Facility Agent shall promptly distribute that payment as if it
            were made by the Borrower or the relevant Guarantor, as the case may
            be; and

      (iii) as between the Borrower and the Lenders, that excess amount shall be
            treated as having been paid to the Lenders to which (and in the
            proportions in which) it is distributed under (ii) above, rather
            than as having been paid to that Lender.

      Within 2 Banking Days after any Lender receives or recovers any such sum
      otherwise than by payment through the Facility Agent, that Lender shall
      notify the Facility Agent of the amount and currency so received or
      recovered, how it was received or recovered and whether it represents
      principal, interest or other sums. If all or part of any amount so
      received or recovered by that Lender (the "RELEVANT LENDER") required
      thereafter to be repaid to the Borrower or another obligor, as the case
      may be, has to be refunded by it (with or without interest), each Lender
      to whom any part of that amount has been distributed shall repay to the
      Facility Agent for the account of the Relevant Lender (within 2 Banking
      Days after receiving a request from the Facility Agent on behalf of the
      Relevant Lender) its proportionate share of the amount to be repaid to the
      Borrower or, as the case may be, other obligor and of any interest
      required to be paid by the Relevant Lender on that amount in respect of
      all or any part of the period from the date of the relevant distribution
      to the date of that payment to the Relevant Lender.

      Any amount received or recovered by a Lender under a novation, assignment,
      sub-participation or the like shall be ignored for the purpose of this
      Clause 20.2. Furthermore, a Lender shall not be obliged to share any
      amount which it has (i) alone

                                     - 62 -

      received on its own account under Clause 14 (Changes in Circumstances) or
      (ii) received or recovered as a result of taking legal proceedings with
      any other Lender which had an opportunity to participate in those legal
      proceedings but did not do so and did not take separate legal proceedings.

      The provisions of this Clause 20.2 shall not, and shall not be construed
      so as to, constitute a charge by a Lender over all or any part of a sum
      received or recovered by it in the circumstances mentioned in Clause 20.2.

20.3  FLOOR GUARANTEE

      For the avoidance of doubt, nothing contained in this Clause 20 shall in
      any way restrict the Initial Lenders or other Beneficiaries under (and as
      defined in) the Floor Guarantee from recovering and retaining for their
      own exclusive benefit amounts received or recovered by them under or in
      respect of the Floor Guarantee.
