   4



         THIS CREDIT AGREEMENT, dated as of December 17, 1996, is made by and
between ROWAN COMPANIES, INC., a Delaware corporation, as the Shipowner, and
CITIBANK, N.A., a national banking association, as the Lender.

                                   BACKGROUND

WHEREAS:

         (A)     by this Agreement, the Lender has established a credit
facility (the "Credit Facility") in the amount of $153,091,000, pursuant to
which the Lender shall, subject to the terms and conditions hereof, extend
financing to the Shipowner (i) for the manufacture, construction, fabrication,
financing and purchase by the Shipowner of the Vessel; (ii) for the payment of
the related Construction Period Interest; and (iii) for the payment of the
Guarantee Fees;

         (B)     the establishment of the Credit Facility is in reliance upon
the commitment of the United States to guarantee the payment of the unpaid
interest on, and the unpaid balance of the principal of, the Floating Rate
Note, including interest accruing between the date of an Indenture Default
under the Floating Rate Note and the payment in full of the Guarantee;

         (C)     a condition to the Lender's extension of the Credit Facility
under this Agreement is the Lender's timely receipt of Certificates Authorizing
Disbursement and issuance of the Guarantee of the Floating Rate Note; and

         (D)     the Credit Facility may be utilized by the Shipowner in
accordance with the terms and conditions of this Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the parties hereto agree as follows:

         SECTION 1.  DEFINITIONS AND PRINCIPLES OF CONSTRUCTION

         1.01    Defined Terms.  For the purposes of this Agreement, unless
otherwise defined herein, defined terms shall have the meanings specified in
Exhibit 1 hereto.

         1.02    Principles of Construction.

         (a)     The meanings set forth for defined terms in this Agreement
shall be equally applicable to both the singular and plural forms of the terms
defined.

         (b)     Unless otherwise specified, all references in this Agreement
to Annexes or Exhibits are to Annexes or Exhibits in or to this Agreement.

                                      -2-


         (c)     The headings of the Sections in this Agreement are included
for convenience only and shall not in any way affect the meaning or
construction of any provision of this Agreement.

         SECTION 2.  THE CREDIT FACILITY

         2.01    Amount.  The Lender hereby establishes the Credit Facility,
upon the terms and conditions set forth in this Agreement, in favor of the
Shipowner in the maximum amount of $153,091,000 (the "Credit Facility Amount"),
to enable the Shipowner to finance: (i) the manufacture, construction,
fabrication, financing and purchase of the Vessel; (ii) Construction Period
Interest; and (iii) the Guarantee Fees.  The Lender will, subject to the terms
and conditions provided herein, be obligated to fund under the Credit Facility
the amount (the "Available Amount") which is equal to the excess, if any, of
the Credit Facility Amount over the outstanding principal amount evidenced by
the Floating Rate Note ("Outstanding Principal").

         2.02    Availability.  Disbursements under the Credit Facility may be
made once a calendar month and up to and including the Final Disbursement Date.
"Final Disbursement Date" shall mean either October 31, 1998 or, if earlier,
the date on which the Available Amount under the Credit Facility is cancelled
in accordance with Section 9.01 or reduced to zero.

         2.03    Disbursements and Minimum Amount of Utilizations.  Upon
satisfaction of Sections 3.01, 5.01 and 5.02, disbursements shall be made by
advances from the Lender to the Shipowner ("Disbursements") in accordance with
Section 3.01.  Notwithstanding anything in this Agreement to the contrary, the
Shipowner may not request a Disbursement under the Credit Facility for an
amount (a) less than the smaller of (i) $1,000,000 or (ii) the Available Amount
or (b) more than the Available Amount.

         2.04    Floating Rate Note.  Disbursements from the Credit Facility
shall become the indebtedness of the Shipowner to the Lender under the Floating
Rate Note.

         SECTION 3.  DISBURSEMENT REQUIREMENTS

         3.01    Disbursement Procedures.  Upon receipt of each Certificate
Authorizing Disbursement at least five Business Days prior to the proposed
disbursement date, the Lender shall disburse funds in accordance with the terms
of such Certificate Authorizing Disbursement to the Shipowner subject to the
terms of this Agreement; provided that, if the Certificate Authorizing
Disbursement and the request for disbursement referred to therein do not
specify a disbursement date, then the disbursement date shall be the fifth
Business Day (or such earlier or later Business Day as is requested by the
Shipowner and is acceptable to the Lender) following the Lender's receipt of
such Certificate Authorizing Disbursement.  Promptly following each
Disbursement, the Lender shall transmit to the Indenture Trustee a copy of the
Certificate Authorizing Disbursement, a confirmation that the Disbursement was
made, and a copy of Exhibit A to the Floating Rate Note, updated to reflect
such Disbursement and other intervening, related events.

         SECTION 4.  TERMS OF THE CREDIT

         4.01    Principal Repayment.  The Shipowner shall repay all
Outstanding Principal in twenty-four (24) approximately equal, successive
semi-annual installments, with each such installment to be payable on a Payment
Date, provided that, on the last Payment Date, the Shipowner shall repay in
full the remaining Outstanding Principal.

                                      -3-


         4.02    Interest Payment.

         (a)     On each Interest Payment Date the Shipowner shall pay interest
on the Outstanding Principal, calculated at an interest rate per annum equal to
the Applicable Interest Rate therefor, as determined for each successive
Interest Period.  The interest rate on such amount shall be determined by the
Indenture Trustee pursuant to the definition of Applicable Interest Rate.  From
time to time, the Lender will confirm LIBOR, Base Rate, and Applicable Interest
Rate to the Indenture Trustee, provided, however, such confirmation shall not
relieve the Indenture Trustee of its obligations under the Indenture to
determine the Applicable Interest Rate.

         (b)     The Shipowner shall pay to the Person entitled to any Unpaid
Amount, on demand, interest on such Unpaid Amount (to the extent permitted by
applicable law) for each Post Maturity Period at an interest rate per annum
equal to the sum (the "Post Maturity Interest Rate") of (1) two percent (2%),
plus (2) the Post Maturity Applicable Interest Rate.  With respect to any
Unpaid Amounts, the "Post Maturity Applicable Interest Rate" shall mean either
(i) LIBOR on the Quotation Date therefor plus during the Construction Period,
nine-twentieths of one percent (0.45%) per annum and thereafter, one-half of
one percent (0.50%) per annum, or (ii) if, for any such Post Maturity Period,
LIBOR cannot be determined, the rate per annum reasonably determined by the
Person to whom such Unpaid Amount is owed before the last day of such Post
Maturity Period to be that which expresses as a percentage rate per annum the
cost which such Person would incur in funding such Unpaid Amount from whatever
source it reasonably deems appropriate for such Post Maturity Period plus
during the Construction Period, nine-twentieths of one percent (0.45%) per
annum and thereafter, one-half of one percent (0.50%) per annum or (iii) if any
such Unpaid Amount is an Accelerated Repayment, then during the first Post
Maturity Period the rate which would have been applicable to such Unpaid Amount
had it not so fallen due.  In the absence of an Indenture Default, any interest
which shall have accrued under this Section 4.02(b) in respect of an Unpaid
Amount shall be due and payable and shall be paid by the Shipowner on demand on
such dates as the Person to whom such Unpaid Amount is owed may specify by
written notice to the Shipowner, or if there is an Indenture Default, any
interest which shall have accrued under this Section 4.02(b) in respect of an
Unpaid Amount shall be due and payable immediately and shall be paid by the
Shipowner without demand and any payment by, or on behalf of, the Shipowner
hereunder shall be governed by Section 7.02 and the provisions of the last
paragraph of Section 9.03.

         As used herein, "Unpaid Amount" means all or any part of principal,
accrued interest, fees or other amounts owing to the Lender under this
Agreement or the Floating Rate Note which is not paid in full when and as due
and payable, whether at Stated Maturity, by acceleration or otherwise, or any
sum due and payable by the Shipowner to the Lender under any judgment of any
court or arbitral tribunal in connection with this Agreement which is not paid
on the date of such judgment; provided, however, that it is agreed that Unpaid
Amount shall not include any part of the principal and interest on the Floating
Rate Note, except that Unpaid Amount shall include all such amounts thereof as
are not paid by the Shipowner as and when they are due but are paid by the
Shipowner prior to payment thereof by the Secretary.  "LIBOR" shall mean, in
relation to any Post Maturity Period (other than the first Post Maturity Period
contemplated by clause (iii) of Section 4.02(b)), the rate of interest per
annum (rounded upward, if necessary, to the nearest 1/16 of 1%) last quoted by
the principal London office of CITIBANK, N.A. prior to the close of business at
such London office on the Quotation Date for the offering to leading banks in
the London interbank market of U.S. Dollar deposits on an overnight basis and
in an amount comparable to the Unpaid Amount to which LIBOR is to apply.
"Accelerated Repayment" shall mean any part of the principal of the Floating
Rate Note which became due and payable on a day other than its Payment Date.
"Post Maturity Period" shall mean with respect to the period from the date an
Unpaid Amount was due until such amount shall have been paid in full, each
successive period, the first of which shall start on the date such Unpaid
Amount was due (or the date of any such judgment or arbitral award, if earlier)
and each other of which shall start on the last day of the preceding such
period, and the duration of each of which shall be one day, or if LIBOR
applies, then from and including the Quotation Date for such Post Maturity
Period to but excluding the next Quotation Date or such other duration selected
by the Person to whom such Unpaid Amount is due, provided, however, that in the
case of any Accelerated Repayment, the first such Post Maturity Period
applicable thereto shall be of a duration equal to the unexpired portion of its
then applicable Interest Period.  "Quotation Date" in relation to any Post
Maturity Period means the day on which quotations would ordinarily be given by
CITIBANK, N.A. in the London interbank market
   7
                                      -4-


for dollar deposits for delivery on the first day of that period, provided,
however, that if, for any such Post Maturity Period, quotations would
ordinarily be given on more than one date, the Quotation Date for that period
shall be the last of those dates.

         4.03    Prepayment.  (a) The Shipowner may from time to time prepay on
any Interest Payment Date all or part of the Outstanding Principal evidenced by
the Floating Rate Note, provided that:  (i) any partial prepayment shall be in
a minimum principal amount of $10,000,000, unless otherwise required by the
Indenture; (ii) the Shipowner shall have given the Lender and the Indenture
Trustee prior written notice of the prepayment (which shall be not less than 40
nor more than 60 days); (iii) the Shipowner shall have paid in full all amounts
due under this Agreement as of the date of such prepayment, including, without
limitation, interest which has accrued to the date of prepayment on the amount
prepaid and all other amounts payable hereunder relating to the prepayment; and
(iv) any amount prepaid hereunder shall not be considered part of the Available
Amount.

         (b)  Upon delivery to the Shipowner and the Secretary of the
instrument satisfying and discharging the Indenture contemplated by Section
12.01 of the Exhibit 1 to the Indenture, all of the Shipowner's indebtedness,
liabilities and obligations under this Agreement and the Fee Letter shall
become immediately due and payable without demand upon, or notice to, the
Shipowner.

         (c)  Notwithstanding any other provision to the contrary herein, the
Shipowner or the Secretary (after the Secretary's assumption of the Floating
Rate Note pursuant to Section 6.09 of Exhibit 1 to the Indenture) may from time
to time prepay all or part of the principal amount of the Floating Rate Note
without any prepayment penalty or premium in accordance with Article III of
Exhibit 1 to the Indenture.

         4.04    Recapture.  (a) The Shipowner shall pay to the Lender, upon
the written request of the Lender, such amounts as shall be sufficient (in the
reasonable judgment of the Lender) to compensate the Lender for any loss,
expense or liability (including, without limitation, any loss, expense or
liability incurred by reason of the liquidation or redeployment of deposits
from third parties or in connection with obtaining funds to make or maintain
any Disbursement) which the Lender reasonably determines is attributable to:

         (i)   any failure to make scheduled payments on a Payment Date or any
payment due in connection with any Redemption; or

         (ii)  any failure by the Shipowner to borrow any advance for which a
Certificate Authorizing Disbursement has been issued; or

         6.02    Taxes.

         (a)     The Shipowner agrees to pay all amounts owing by it under this
Agreement or the Floating Rate Note free and clear of and without deduction for
any and all present and future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding in the case

         (i)     that, if the Shipowner is prevented by operation of law from

amount necessary to yield to the Lender fees or expenses in the amounts
provided for in this Agreement after the provision for the payment of all such
Taxes and Other Taxes;

         (ii)    that the Shipowner shall, at the request of the Lender,

         (iii)  that the Shipowner shall hold the Lender harmless from and
against the full amount of Taxes and Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts
payable under this Section 6.02) and any and all liabilities (including,
without limitation, penalties, interest and expenses) arising from, or with
respect to, any Taxes or Other Taxes (whether or not properly or legally
asserted) and whether paid, or payable, by the Shipowner, the Lender or any
other Person;

         (iv)    that, at the request of the Lender, the Shipowner shall
provide the Lender within the later of thirty (30) calendar days after such
request or thirty (30) calendar days after the payment of such Taxes or Other

         (c)     Notwithstanding anything to the contrary contained herein, the
agreements in this Section 6.02 shall survive the termination of this Agreement
and the payment of the Floating Rate Note and all other amounts due hereunder.

         6.03    Expenses.  The Shipowner agrees, whether or not the
transactions hereby contemplated shall be consummated, to pay, or reimburse the
Lender promptly upon demand for the payment of all reasonable and duly
documented costs and expenses arising in connection with the preparation,
printing, execution, delivery, registration, implementation, modification of or
waiver or consent under this Agreement, the Floating Rate Note or the
Indenture, including, without limitation, the reasonable and duly documented
out-of-pocket expenses of the Lender (incurred in respect of
telecommunications, mail or courier service, travel and the like), and the fees
and expenses of counsel for the Lender.  The Shipowner shall also pay all of
the costs and expenses (including, without limitation, the fees and expenses of
counsel) incurred by or charged to the Lender in connection with the amendment
or enforcement of this Agreement, the Floating Rate Note or the Indenture or
the protection or preservation of any right or claim of the Lender arising out
of this Agreement, the Floating Rate Note or the Indenture.

         6.04    Additional or Increased Costs.

         (a)     If, due to either (i) the introduction of or any change in or
in the interpretation of any law or regulation or (ii) the compliance with any
guideline or request from any central bank or other governmental authority
(whether or not having the force of law), there shall be any increase in the
cost to the Lender of agreeing to make or making, funding or maintaining the
Disbursements or the Credit Facility, then the Shipowner shall from time to
time, upon demand by the Lender, pay to the Lender additional amounts
sufficient to compensate the Lender for such increased cost.

         (b)     If the Lender determines that compliance with any law or
regulation or any guideline or request from any central bank or other
governmental authority (whether or not having the force of law) affects or
would affect the amount of capital required to be maintained by the Lender or
any corporation controlling the Lender and that the amount of such capital is
increased by or based upon the existence of the Lender's commitment to lend
hereunder and other commitments of this type, then, upon demand by the Lender,
the Shipowner shall immediately pay to the Lender, from time to time as
specified by the Lender, additional amounts sufficient to compensate the Lender
or such corporation in the light of such circumstances, to the extent that the
Lender reasonably determines such increase in capital to be allocable to the
existence of the Lender's commitment to lend hereunder.

         (c)     The Lender shall take such reasonable steps as it shall
determine to minimize amounts demanded under this Section 6.04. In the event
that the Lender transfers the booking office of the Credit Facility or the
Floating Rate Note to minimize amounts demanded under this Section 6.04, any
costs and expenses incurred in such transfer shall be paid by the Shipowner.

         (d)     Each demand for payment by the Lender under this Section 6.04
shall be accompanied by a certificate showing in reasonable detail the basis
for the calculation of the amounts demanded, which certificate, in the absence
of manifest error, shall be conclusive and binding for all purposes.

         (e)     The Lender shall notify the Shipowner of any event occurring
after the date of this Agreement which entitles the Lender to compensation
pursuant to this Section 6.04, as promptly as practicable, and in any event
within ninety (90) days after it has knowledge of such event and has determined
that a request for compensation hereunder shall be made.  The Shipowner shall
not be obligated to reimburse the Lender for any loss or cost incurred more
than ninety (90) days prior to delivery of notice to the Shipowner by the
Lender requesting compensation under this Section 6.04.

executory or judicial proceeding; or a bankruptcy, arrangement, readjustment of
debt, dissolution, liquidation or similar executory or judicial proceeding
shall be instituted against the Shipowner and shall remain undismissed,
undischarged or unstayed for a period of thirty (30) days; or

         (d)     an Indenture Default has occurred;

then, and in any such event, and at any time thereafter, if such event is
continuing, and if there is no Indenture Default (or if there is an Indenture
Default, only after the Secretary has received all payments due under the
Secretary's Note and the Mortgage), the Lender (by written notice to the
Shipowner), shall have the right to institute any judicial or other proceedings
under this Agreement to recover all amounts owing under this Agreement.  The
Lender agrees that so long as an Indenture Default exists, all amounts received
during such period from, or on
   16
                                      -13-


behalf of, the Shipowner shall be applied in the manner set forth in Section
7.02.  Notwithstanding an Event of Default, the Lender may not terminate the
Available Amount of the Credit Facility without the Secretary's consent;
provided, however, that the Shipowner's use of the Available Amount of the
Credit Facility shall remain subject to the requirements of Sections 2.02,
3.01, and 5.02.  Except as expressly provided above in this Section 9.03,
presentment, demand, protest and all other notices of any kind are hereby
expressly waived.  Notwithstanding any other provision of this Agreement, if
Section 9.03(c) is applicable, the Lender may file appropriate claims in
connection therewith, but shall apply any funds collected as a consequence of
said filings in accordance with the provisions of Section 7.02 of this
Agreement.

         SECTION 10.  GOVERNING LAW AND JURISDICTION

         10.01     Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

         10.02     Submission to Jurisdiction.  Each of the Shipowner and the
Lender hereby irrevocably agrees that any legal suit, action or proceeding
arising out of or relating to this Agreement, or any of the transactions
contemplated hereby, may be instituted by the other parties hereto in the
Courts of the State of New York or the Federal Courts sitting in the Borough of
Manhattan, City of New York, State of New York.  Each of the Shipowner and the
Lender hereby irrevocably waives, to the fullest extent permitted by law, any
objection which it may have now or hereafter to the laying of the venue or any
objection based on forum non conveniens, or based on the grounds of
jurisdiction with respect to any such legal suit, action or proceeding and
irrevocably submits generally and unconditionally to the jurisdiction of any
such court in any such suit, action or proceeding.  Each of the Shipowner and
the Lender agrees that a judgment, after exhaustion of all available appeals,
in any such action or proceeding shall be conclusive and binding upon it and
may be enforced in any other jurisdiction by suit upon such judgment, a
certified copy of which shall be conclusive evidence of the judgment.  Each of
the Shipowner and the Lender waives personal service of any summons, complaint,
or other process, which service may be made by such or any other means
permitted by New York law.

         10.03     Waiver of Security Requirements.  To the extent the
Shipowner may, in any action or proceeding arising out of or relating to this
Agreement be entitled under applicable law to require or claim that the Lender
post security for costs or take similar action, the Shipowner hereby
irrevocably waives and agrees not to claim the benefit of such entitlement.

         10.04     No Limitation.  Nothing in this Section 10 shall affect the
right of the Lender to serve process in any manner permitted by law or to
commence legal proceedings or otherwise proceed against the Shipowner in any
jurisdiction; provided, however, that except as provided in Section 9.03, in
the event of an Indenture Default, the Lender may not proceed against the
Shipowner without the Secretary's consent unless the Secretary has received
full payment under the Secretary's Note.

         SECTION 11.  MISCELLANEOUS

         11.01     Computations.  Each determination of an interest rate, fee
or other amounts by the Lender or any other Person pursuant to any provision of
this Agreement, the Fee Letter or the Floating Rate Note, in the absence of
manifest error, shall be conclusive and binding on the Shipowner.  All
computations of interest and fees hereunder and under the Floating Rate Note
shall be made on the basis of a year of three hundred sixty-five  (365) days
and actual days elapsed; provided, however, that LIBOR shall be determined on
the basis of a year of 360 days and actual days elapsed.

         11.02     Notices.  Except as otherwise specified, all notices given

         11.03     Disposition of Indebtedness.  Once the Shipowner has
completely drawn down on the Credit Facility and the Available Amount is zero,
the Lender may sell, assign, transfer, negotiate, or otherwise dispose of all
or any part of its interest in all or any part of the Shipowner's indebtedness
under this Agreement and the Floating Rate Note to any party (collectively, a
"Disposition of Indebtedness"), and any such party shall enjoy all the rights
and privileges of the Lender under this Agreement and the Floating Rate Note;
provided, however, that each Disposition of Indebtedness to any Person other
than a domestic Affiliate of the Lender shall require the prior written consent
of the Shipowner (which consent shall not be unreasonably withheld or delayed);
provided, further, however, that the Lender may pledge or grant participation
in all or any part of its interest in all or any part of the Shipowner's
indebtedness under this Agreement and the Floating Rate Note to any party at
any time without the Secretary's prior written consent so long as the Lender's
commitment to lend the Available Amount under this Agreement is not affected
thereby and without the Shipowner's prior written consent.  The Shipowner
shall, at the request of the Lender, execute and deliver to the Lender or to
any party that the Lender may designate, any such further instruments as may be
necessary or desirable to give full force and effect to a Disposition of
Indebtedness by the Lender.

         11.04     Disclaimer.  The Lender shall not be responsible in any way
for the performance of the Construction Contract or any other Shipowner
Document, and no claim against the Shipbuilder or any other Person with respect
to the performance of the Construction Contract will affect the obligations of
the Shipowner under this Agreement or the Floating Rate Note.

         11.05     No Waiver; Remedies Cumulative.  No failure or delay on the
part of the Lender in exercising any right, power or privilege under this
Agreement, the Floating Rate Note or the Indenture and no course of dealing
between or among the Shipowner and the Lender shall operate as a waiver of the
rights of the Shipowner and the Lender against each other under this Agreement;
nor shall any single or partial exercise of any right, power or privilege
hereunder or under the Floating Rate Note or the Indenture preclude the
Shipowner and the Lender from exercising against each other any other right,
power or privilege hereunder.  The rights and remedies expressly provided
herein are cumulative and not exclusive of any rights or remedies which the
Lender would otherwise have.  No notice to or demand on the Shipowner in any
case shall entitle the Shipowner to any other or further notice or demand in
similar or other circumstances or constitute a waiver of the rights of the
Lender under this Agreement to any other or further action in any circumstances
without notice or demand.  Notwithstanding any other provision to the contrary
herein, no provision in this Agreement or any other related agreement preserves
any rights in favor of the parties against the Secretary in the event that
either party fails or delays to exercise any rights, powers, or privileges
under this Agreement, the Floating Rate Note or the Indenture or engages in any
particular course of dealing.

         11.06     Currency.  All payments of principal, interest, fees or
other amounts due hereunder and under the Floating Rate Note shall be made in
Dollars, regardless of any law, rule, regulation or statute, whether now or
hereafter in existence or in effect in any jurisdiction, which affects or
purports to affect such obligations.

         11.07     Severability.  To the extent permitted by applicable law,
the illegality or unenforceability of any provision of this Agreement shall not
in any way affect or impair the legality or enforceability of the remaining
provisions of this Agreement.

         11.08     Amendment or Waiver.  This Agreement may not be changed,
discharged or terminated without the written consent of the parties hereto, and
no provision hereof may be waived without the written consent of the party to
be bound thereby.  There may be no change, discharge, termination or claim of
waiver of the terms of this Agreement without the prior written consent of the
Secretary, who is entitled to enforce his rights under this Agreement as an
intended third party beneficiary to this Agreement.  The parties hereto
acknowledge, however, that nothing in this Agreement creates in either the
Shipowner or the Lender any right whatsoever against the Secretary.
   19
                                      -16-


         11.09     Indemnification.  Without limiting any other rights that the
Lender may have hereunder or under applicable law, the Shipowner hereby agrees
to indemnify the Lender from and against any and all damages, losses, claims,
liabilities and related costs and expenses, including reasonable attorneys'
fees and disbursements (all the foregoing being collectively referred to as
"Indemnified Amounts") awarded against or incurred by the Lender arising out of
or as a result of this Agreement or the Floating Rate Note excluding, however,
Indemnified Amounts to the extent resulting from gross negligence or willful
misconduct on the part of the Lender.  In the event of an Indenture Default,
all amounts received by the Lender pursuant to such indemnification after an
Indenture Default shall be held and paid in the manner required by Section
7.02.

         11.10     Benefit of Agreement.  This Agreement shall be binding upon
and inure to the benefit of and be enforceable by the respective successors and
assigns of the parties hereto; provided, however, that the Shipowner may not
assign any of its rights or obligations hereunder without the prior written
consent of the Lender and, to the extent set forth in paragraph 11.03 hereof,
the Secretary.

         11.11     Waiver of Jury Trial.  Each of the Shipowner and the Lender
waives its respective rights to a trial by jury of any claim or cause of action
based upon or arising out of or related to this Agreement, any assignment or
the transactions contemplated hereby, in any action, proceeding or other
litigation of any type brought by any party against the other parties, whether
with respect to contract claims, tort claims, or otherwise.  Each of the
Shipowner and the Lender agrees that any such claim or cause of action shall be
tried by a court trial without a jury.  Without limiting the foregoing, the
parties further agree that their respective right to a trial by jury is waived
by operation of this section as to any action, counterclaim or other proceeding
which seeks, in whole or in part, to challenge the validity or enforceability
of this Agreement, any assignment or any provision hereof or thereof.  This
waiver shall apply to any subsequent amendments, renewals, supplements or
modifications to this Agreement or any assignment.

         11.12     Execution in Counterparts.  This Agreement may be executed
in any number of counterparts, each of which when so executed shall be deemed
to be an original and all of which when taken together shall constitute one and
the same Agreement.  Delivery of an executed counterpart of a signature page to
this Agreement by facsimile shall be effective as delivery of a manually
executed counterpart of this Agreement.

         11.13     Shipowner Documents.  Notwithstanding the provisions of this
Agreement, in any conflict between this Agreement and the provisions of the
Shipowner Documents, the Shipowner Documents shall govern the agreement between
the parties hereto, but only with respect to the subject matter thereof.
Notwithstanding the previous sentence, any provision in the Indenture (or any
other agreement the Shipowner has entered into with any other Person)
purporting to release the Shipowner of any indebtedness, liability or
obligation shall not apply to any indebtedness, liability or obligation of the
Shipowner hereunder and no termination of the Indenture (or any other agreement
the Shipowner has entered into with any other Person) shall affect the
continued effectiveness of this Agreement, which shall continue in full force
and effect until the Credit Facility has been terminated and all indebtedness,
liabilities and obligations of the Shipowner have been fully discharged and
satisfied, the Floating Rate Note have been paid, satisfied and discharged in
full, and there has elapsed a year and a day from the last payment received
from, or on behalf, of the Shipowner.  However, this Section 11.13 shall have
no affect on the relationships established and the agreements entered into by
the parties to the Shipowner Documents (and such other agreements the Shipowner
has entered into with any other Person), in each case to which the Lender is
not a party in its capacity as the Lender hereunder.

         11.14     Entire Agreement.  This Agreement, the Fee Letter and the
Floating Rate Note contain the entire agreement among the parties hereto
regarding the Credit Facility.

                               SPECIAL PROVISIONS


         THIS TRUST INDENTURE, is dated as of December 17, 1996 (said Trust
Indenture, as the same may be amended, modified or supplemented from time to
time as permitted hereunder, herein called the "Indenture"), is between (i)
ROWAN COMPANIES, INC., a Delaware corporation (herein called the "Shipowner"),
and (ii) CITIBANK, N.A., a national banking association, (said bank, any
successor or assign hereunder, herein called the "Indenture Trustee").

                                   RECITALS:

         A. As provided in Article Fifth hereof, the terms defined in Schedule
A to this Indenture shall have the respective meanings stated in said Schedule;

         B. The Shipowner has duly executed this Indenture, and duly authorized
the issuance hereunder of $153,091,000 principal amount of its Obligations
pursuant to Section 2.03 of Exhibit 1 to this Indenture (herein together with
any Obligations issued in respect thereof pursuant to Sections 2.09, 2.10, 2.12
and 3.10(b) of said Exhibit 1, called the "Obligations") designated "United
States Government Guaranteed Ship Financing Obligations, GORILLA V Series;"

         C.  The Obligations will be issued by the Shipowner to aid in the
financing of the cost of construction of a self-elevating mobile offshore
drilling unit to be named the GORILLA V (the "Vessel");

         D.      To aid in financing the construction of the Vessel, the
Shipowner has entered into a credit agreement (the "Credit Agreement") with
CITIBANK, N.A., a national banking association as Lender, providing for the
delivery of no more than $153,091,000 principal amount of note designated
"United States Government Guaranteed Ship Financing Obligations, GORILLA V
Series";

         E. Under the Authorization Agreement in the form set forth as Exhibit
4 hereto, the Secretary, on behalf of the United States, has agreed and will
agree to execute on the Obligations to be issued, a Guarantee of the payment of
the unpaid interest to the date of such payment on, and the unpaid balance of
the principal of, such Obligation under the provisions of Title XI of the Act,
and the Indenture Trustee is authorized to cause the Guarantees, bearing the
facsimile signature of the Secretary, and the facsimile seal of the United
States Department of Transportation, to be imprinted on the Obligations, and to
authenticate and deliver the Obligations and the Guarantees issued on the
Closing Date and from time to time thereafter, such agreements and
authorizations being subject to the conditions set forth in the Authorization
Agreement;

         F. Pursuant to Section 1104(b)(5) of the Act, the Secretary will
determine that the interest to be borne by the Obligations (exclusive of
charges for the guarantee fee and service charges, if any) is reasonable; and

         G. All actions necessary have been or will be taken in order (1) to
make the Obligations, when executed by the Shipowner, authenticated by the
Indenture Trustee and issued under the Indenture, the valid, binding and legal
obligations of the Shipowner in accordance with their terms, (2) to make the
Guarantees to be endorsed on the

Indenture Trustee and delivered under this Indenture, the valid, binding and
legal obligations of the United States in accordance with their terms, and (3)
to make this Indenture the valid, binding and legal agreement of the parties
hereto in accordance with its terms.

         NOW THEREFORE, in consideration of the premises, of the mutual
covenants herein contained, of the purchase of the Obligations by the Holder
and of other good and valuable consideration, the receipt and adequacy of which
the parties hereby acknowledge, and for the equal and proportionate benefit of

                              CERTAIN REDEMPTIONS

         (a) Scheduled Mandatory Redemption. The Obligations are subject to
redemption at a Redemption Price equal to 100% of the principal amount thereof,
together with interest accrued thereon to the applicable Redemption Date,
through the operation of scheduled repayment providing for the semi-annual
redemption on January 1 and July 1 of each year, commencing January 1, 1999, of
$6,380,000 principal amount of Obligations (or such lesser principal amount of
Obligations as shall then be outstanding), which amount represents
approximately one twenty-fourth (1/24) of the Original Principal Amount of
Obligations, plus interest accrued thereon to the Redemption Date.  There shall
be a final redemption of the remaining outstanding principal on the earlier of
(i) July 1, 2000, or (ii) two (2) years after the Delivery Date.

         Notwithstanding the foregoing provisions of this subsection (a), if
the principal amount of Outstanding Obligations shall be reduced by reason of
any redemption pursuant to Section 3.04 of Exhibit 1 to this Indenture, the
principal amount of Obligations to be redeemed pursuant to this subsection (a)
on each subsequent Redemption Date for such Obligations shall be reduced by an
amount equal to the principal amount of such Obligations retired by reason of
such redemption pursuant to Section 3.04 of Exhibit 1 hereto divided by the
number of Redemption Dates (including the Stated Maturity of such Obligations)
scheduled thereafter to July 1, 2000 (subject to such increase as shall be
necessary so that the total principal amount of Obligations to be redeemed on
any such Redemption Date shall be an integral multiple of $1,000); provided
that, the entire unpaid principal amount of the Outstanding Obligations shall
be paid not later than July 1, 2000.  The Shipowner shall, in accordance with
Section 3.02(d) of Exhibit 1 hereto, promptly after each redemption pursuant to
said Section 3.04, furnish to the Secretary, the Indenture Trustee and each
Holder a revised table of scheduled repayments reflecting the reductions made
pursuant to this subsection (a) as a result of such redemption.

         (b)     Optional Redemption of Obligations Without Premium.
At its option, the Shipowner may without premium,

                 (i) prepay on any Interest Payment Date the Obligation, in
whole or in part, in a minimum principal amount of $10,000,000, at a Redemption
Price equal to 100% of the principal amount thereof together with interest
accrued thereon to the Redemption Date, or

                 (ii) redeem or prepay the Obligation, in whole or in part, on
a Redemption Date designated by the Shipowner, from the proceeds from the
issuance of fixed rate notes.


         (c)     If the Shipowner shall elect to make any such optional
redemptions pursuant to this Article, the Shipowner shall, at least 40 days but
not more than 60 days prior to the date fixed for redemption, deliver to the
Indenture Trustee a Request stating that the Shipowner intends to exercise its
rights as above set forth to make such optional redemptions and specifying the
Redemption Date and the principal amount which the Shipowner intends to redeem
on such date.

indemnity which is satisfactory in form and substance to the Secretary, the
Shipowner, and the Indenture Trustee, executed and delivered by an
institutional Holder having a capital and surplus of at least $100,000,000
shall be considered sufficient indemnity to the Secretary, the Shipowner, and

delivery of any new Obligations or the making of any payment as contemplated by
said Section 2.12.

         (i)     Concerning Payment of the Obligations.  Notwithstanding
anything to the contrary in Exhibit 1 hereto, the Obligations to be issued

         (j)  Concerning Section 3.02.  Section 3.02(c) and (d) are revised to 
read as follows:

         (c) Scheduled Redemptions.  If the Obligations of any series and
         Stated Maturity or the Special Provisions hereof or the Supplemental
         Indenture establishing such series shall so provide, such Obligations
         shall be subject to (i) scheduled redemption through the operation of
         a mandatory redemption schedule, in such amounts, at such times and
         subject to such credits (if any) as may be specified therein, and (ii)
         redemption at the option of the Shipowner, in connection with the
         operation of any such mandatory redemption schedule, in such
         additional amounts and subject to such conditions as may be specified
         therein.

         (d) Adjustments of Redemption Payments.  If the Obligations of any
         series and Stated Maturity or the Special Provisions hereof or of the
         Supplemental Indenture establishing such series provide for an
         adjustment in scheduled redemption payments as a result of any
         redemption or cancellation of Obligations, the Shipowner shall
         recompute the remaining scheduled redemption payments pursuant to such
         provisions and shall, at least 60 days prior to the next Interest
         Payment Date which occurs at least 60 days following any such
         redemption or cancellation of Obligations of such series requiring
         such recomputation, submit to the Secretary for his review such
         recomputation to ascertain compliance with the provisions of such
         Obligations or the Special Provisions hereof or such Supplemental
         Indenture, and table of revised





                                       6
   56


         mandatory redemption schedule payments on the Obligations of such
         series reflecting the adjustments made pursuant to such provisions as
         a result of such redemption or cancellation. Upon advice by the
         Secretary that he finds such recomputation to comply with such
         provisions, the Shipowner shall submit said table to the Indenture
         Trustee and the Indenture Trustee shall promptly submit a copy thereof
         to each Holder of an Obligation of such series.

         (k)     Concerning Section 3.03.  The date required by Section 3.03 of
Exhibit 1 hereto is the earlier of July 1, 2000, or (ii) two (2) years from the

                          which Holders of such Obligations are entitled shall
                          upon the Request of the Shipowner be paid by the

         or settlors of any trust for which the Shipowner is trustee, to the
         extent paid over to it or them) for the payment thereof, and the
         Indenture Trustee or such Paying Agent, as the case may be, shall
         thereupon be relieved from all responsibility to such Holders
         therefor.  No such Request, publication or payment shall be construed

         immediately available funds sufficient for such payment (after taking
         into account any amounts then held by the Indenture Trustee or such
         Paying Agent and available for such payment) with irrevocable

         Obligations shall have the right, by an Act of Obligees, to direct the
         Indenture Trustee:

                        (2) to direct the time, method and place of the
                 exercise of any such right or the enforcement of any such
                 remedy;

         provided that, subject to Section 7.03, the Indenture Trustee shall
         have the right not to take any such action if it shall determine in
         good faith that the action would involve it in personal liability, or
         would be unjustly prejudicial to the Obligees not parties to such
         direction.

         Anything in this Section 6.06(a) to the contrary notwithstanding, the
         Indenture Trustee shall be obligated to demand payment of the

         shall be protected (subject to paragraph (c) of this Section) in

         Officer's Certificate as to the existence or nonexistence of any fact.

         exercise of any of its rights or powers.

         Trustee for, and hold it harmless against, any loss, liability or
         expense which it may incur or suffer without negligence or bad faith
         in acting under this Indenture or the Authorization Agreement. The
         compensation of the Indenture Trustee shall not be limited to the
         compensation provided by law for a trustee acting under an express
         trust.  The obligations of the Shipowner under this Section 7.04 shall
         survive the termination of the Indenture and resignation or removal of
         the Indenture Trustee.

         (x)  Concerning Sections 8.01 and 8.02.  Sections 8.01 and 8.02 are
revised to read as follows:

         SECTION 8.01.  Consolidation, Merger or Sale by Shipowner.  Nothing in
         this Indenture shall prevent any lawful consolidation or merger of the
         Shipowner with or into any other Person, or any sale of the Vessel to
         any other Person lawfully entitled to acquire and operate the Vessel
         or any sale by the Shipowner of all or substantially all of its assets
         to any other Person; provided that, except where the Shipowner shall
         be the Person surviving a merger or consolidation, the Person formed
         by or surviving such consolidation or merger, or to which the sale of
         the Vessel shall be made, shall, by Supplemental Indenture, expressly
         assume the payment of the principal of and interest (and premium, if
         any) on the Outstanding Obligations relating to the Vessel in
         accordance with the terms of the Obligations and of the Indenture and
         shall expressly assume the performance of the agreements of the
         Shipowner in the Indenture; provided further, that to the extent the
         Outstanding Obligations are not so assumed, the Shipowner shall redeem
         or cause to be redeemed the Outstanding Obligations, such redemption
         to be in accordance with the terms of the Obligations and of the
         Indenture.  When a Person so assumes this Indenture and the
         Outstanding Obligations, the Supplemental Indenture shall discharge
         and release the Shipowner from any and all obligations thereunder
         relating to the Outstanding Obligations. In the event of such an
         assumption by a Person to whom the Vessel has been sold (a) such
         Person shall succeed to, and be substituted for, and may exercise
         every right and power of the original Shipowner with the same effect
         as if such successor Shipowner had been named as the Shipowner herein
         and (b) the Outstanding Obligations shall be surrendered to the
         Indenture Trustee for appropriate notation or for the issuance of new
         Obligations in exchange for the Outstanding Obligations in the name of
         the successor Shipowner, as required by the Secretary.

         SECTION 8.02.  Sale of the Vessel by the Secretary.  Nothing contained
         in this Indenture shall prevent the sale of the Vessel to any other
         Person by the Secretary, by a court of law or by the Shipowner
         following, in connection with or in lieu of a foreclosure or similar
         action.  Following any such sale (1) the Person to whom the Vessel has
         been sold may, by Supplemental Indenture, expressly assume the payment
         of principal and interest (and premium, if any) on all of the
         Outstanding Obligations in accordance with the terms of the
         Obligations and the Indenture and shall expressly assume the
         performance of the agreements of the Shipowner in the Indenture; and
         (2) in the event such Person does not so assume, the Secretary shall
         prepay or redeem all of the Outstanding Obligations without premium
         pursuant to Section 3.06 hereof; provided that, the Secretary shall
         allow or permit the sale of the Vessel to the original Shipowner or to
         any affiliate of the original Shipowner only if (i) the Secretary has
         not prepaid or redeemed such Obligations prior to such sale, and (ii)
         such purchaser assumes all of the Outstanding Obligations as
         contemplated by the preceding clause (1).  When a Person so assumes
         this Indenture and all of the Outstanding Obligations, the
         Supplemental Indenture shall discharge and release the Secretary from
         any and all obligations





                                       10
   60


         thereunder in the Secretary's capacity as Shipowner relating to the
         Outstanding Obligations.  In the event of such an assumption by a
         Person to whom the Vessel has been sold (a) such Person shall succeed
         to, and be substituted for, and may exercise every right and power of
         the original Shipowner with the same effect as if such successor
         Shipowner had been named as the Shipowner herein and (b) the
         Outstanding Obligations shall be surrendered to the Indenture Trustee
         for appropriate notation or for the issuance of new Obligations in
         exchange for the Outstanding Obligations in the name of the successor
         Shipowner, as required by the Secretary.  Any such sale or the
         execution of a Supplemental Indenture by an successor Shipowner shall
         not discharge or in any manner affect the obligation of the United
         States to pay the Guarantees pursuant to the terms thereof.
