                          1998, among UNION PACIFIC RESOURCES GROUP INC., a
                          Utah corporation (the "Borrower"), the Banks (as
                          hereinafter defined), and CHASE BANK OF TEXAS, N.A.,
                          as Administrative Agent (as hereinafter defined).


                                   ARTICLE I

                        Definitions and Accounting Terms

                 SECTION 1.01.  Certain Defined Terms.  As used in this
Agreement, the following terms shall have the following meanings (such meanings
to be equally applicable to both the singular and plural forms of the terms
defined):

                 "Accepting Banks" has the meaning specified in Section
2.10(a)(i).

                 "Administrative Agent" means Chase Bank of Texas, N.A. and its
permitted successor or successors as administrative agent for the Banks under
this Agreement.

                 "Advance" means any Contract Advance or Competitive Advance.

                 "Affiliate" of a Person means any other individual or entity
who directly or indirectly controls, is controlled by, or is under common
control with that Person; provided that, for purposes of Article IV(k) and
Section 5.02(g) hereof, the Subsidiaries of Borrower shall not be considered
Affiliates of the Borrower or any Subsidiary (including any Restricted
Subsidiary), and Borrower shall not be considered an Affiliate of a Subsidiary
(including any Restricted Subsidiary).  For purposes of such definition,
"control," "controlled by," and "under common control with" mean the
possession, directly or indirectly, of the power to direct or cause the
direction of the management or policies of a Person (whether through ownership
of voting securities or other interests, by contract or otherwise).

                 "Agreement" means this Agreement, as amended, modified and
supplemented from time to time, including, without limitation, any such
supplement in respect of Competitive Advances under Section 2.03.

                 "Alternate Base Rate" means, for any day, a rate per annum
equal to the lesser of (a) the Maximum Rate and (b) the greatest of (i) the
Prime Rate in effect on such day, (ii) the Base CD Rate in effect on such day
plus 1% and (iii) the Federal Funds Effective Rate in effect on such day plus
1/2 of 1%.  For purposes hereof, "Prime Rate" means the rate of interest per
annum, publicly announced from time to time by the Administrative Agent as its
prime rate in effect at its principal office in New York City (which prime rate
may not necessarily represent the lowest or best rate actually charged to a
customer); each change in the Prime Rate shall be effective on the date such
change is publicly announced as effective.  "Base CD Rate" means the sum of (a)
the product of (i) the Three-Month Secondary CD Rate and (ii) 1.00 plus the
Domestic Reserve Percentage and (b) the Assessment Rate.  "Three-Month
Secondary CD Rate" means, for any day, the secondary market rate for
three-month certificates of deposit reported as being in effect on such day
(or, if such day shall not be a Business Day, the next preceding Business Day)
by the Board through the public information telephone line of the Federal
Reserve Bank of New York (which rate will, under the current practices of the
Board, be published in Federal Reserve Statistical Release H.15(519) during the
week following such day), or, if such rate shall not be so reported on such day
or such next preceding Business Day, the average (rounded upwards, if

rating in effect, and in the absence of such amendment the Applicable Margin
will be determined by reference to the available rating; (c) if the ratings
established by Moody's and S&P shall fall within different Categories, the
Applicable Margin shall be determined by reference to the numerically lower
Category (for example, if the rating from S&P is in Category 1 and the rating
from Moody's is in Category 2, the Applicable Margin shall be determined by
reference to Category 1); and (d) if any rating established by Moody's or S&P
shall be changed (other than as a result of a change in the rating system of

such change is first announced by the rating agency making such change. Each
change in the Applicable Margin shall apply during the period commencing on the
effective date of such change and ending on the date immediately preceding the
effective date of the next such change.  If the rating system of either Moody's
or S&P shall change, the Borrower and the Banks shall negotiate in good faith
to amend the references to specific ratings in this definition to reflect such
changed rating system.  If both Moody's and S&P shall cease to be in the
business of rating corporate debt obligations, the Borrower and the Banks shall
negotiate in good faith to agree upon a substitute rating agency and to amend
the references to specific ratings in this definition to reflect the ratings
used by such substitute rating agency.

amount not to exceed at any time outstanding the amount set opposite such

Section 2.01, the Borrower may from time to time borrow under this Section

                                                                              12

12:00 noon (New York City time) on the date of any such Contract Borrowing,
make available for the account of its Applicable Lending Office to the
Administrative Agent at its address referred to in Section 8.02, in same day
funds, such Bank's ratable portion of such Contract Borrowing.  Upon the
Administrative Agent's receipt of such funds and upon fulfillment of the
applicable conditions set forth in Article III, the Administrative Agent will
make such funds available to the Borrower at the Administrative Agent's
aforesaid address.

                 (b)  Each Notice of Contract Borrowing shall be irrevocable
and binding on the Borrower.  In the case of any Contract Borrowing which the
related Notice of Contract Borrowing specifies is to be comprised of Eurodollar
Rate Contract Advances, the Borrower shall indemnify each Bank against any
loss, cost or expense incurred by such Bank as a result of any failure by the
Borrower to complete such Borrowing (whether or not due to a failure to fulfill
on or before the date specified in such Notice of Contract Borrowing the
applicable conditions set forth in Article III), such losses, costs and
expenses to include, without limitation, any loss (including loss of
anticipated profits), cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Bank to fund the
Contract Advance to be made by such Bank as part of such Contract Borrowing
when such Contract Advance, as a result of such failure, is not made on such
date.

                 (c)  Unless the Administrative Agent shall have received
notice from a Bank prior to the date of any Contract Borrowing that such Bank
will not make available to the Administrative Agent such Bank's ratable portion
of such Contract Borrowing, the Administrative Agent may assume that such Bank
has made such portion available to the Administrative Agent on the date of such
Contract Borrowing in accordance with Section 2.02(a) and the Administrative
Agent may, in reliance upon such assumption, make available to the Borrower on
such date a corresponding amount.  If and to the extent that such Bank shall
not have so made such ratable portion available to the Administrative Agent,
such Bank and the Borrower severally agree to repay to the Administrative Agent
forthwith on demand such corresponding amount, together with interest thereon,
for each day from the date such amount is made available to the Borrower until
the date such amount is repaid to the Administrative Agent, at (i) in the case
of the Borrower, the interest rate applicable at the time to Contract Advances
comprising such Contract Borrowing and (ii) in the case of such Bank, an
interest rate equal at all times to the Federal Funds Effective Rate.  If such
Bank shall repay to the Administrative Agent such corresponding amount, such
amount so repaid shall constitute such Bank's Contract Advance as part of such
Contract Borrowing for purposes of this Agreement.

                 (d)  The failure of any Bank to make the Contract Advance to
be made by it as part of any Contract Borrowing shall not relieve any other
Bank of its obligation, if any, hereunder to make its Contract Advance on the
date of such Contract Borrowing, but no Bank shall be responsible for the
failure of any other Bank to make the Contract Advance to be made by such other
Bank on the date of any Contract Borrowing.

Section 2.03 from time to time on any Business Day during the period from the
Closing Date until the Termination Date, in each case on the terms and
conditions hereinafter set forth; provided, however, that at no time shall the
aggregate amount of Contract Advances (other than Term Advances) and
Competitive Advances outstanding exceed the aggregate amount of the
Commitments.  Each Competitive Borrowing shall consist of Competitive Advances
of the same Type made on the same day.

                 (i)  The Borrower may request a Competitive Borrowing under
         this Section 2.03 by delivering to the Administrative Agent (A) in the
         case of a Borrowing consisting of Fixed Rate Competitive Advances, by
         not later than 10:00 a.m. (New York City time) on the Business Day
         prior to the day of the proposed Competitive Borrowing, and (B) in the

         excess thereof) of such Competitive Borrowing, (4) maturity date for

         shall in turn promptly deliver (by cable or telecopy) to each Bank a
         notice of competitive bid request (a "Notice of Competitive Bid
         Request"), in substantially the form of Exhibit A-3, notifying the

         the Borrower and of the terms contained in such Notice of Competitive
         Borrowing.

                 (ii)  Each Bank shall, if, in its sole discretion, it elects
         to do so, irrevocably offer to make one or more Competitive Advances
         to the Borrower as part of such proposed Competitive Borrowing at a

         Competitive Borrowing specified in the Notice of Competitive Borrowing
         delivered with respect thereto, of the maximum amount of each
         Competitive Advance which such Bank would be willing to make as part
         of such proposed Competitive Borrowing (which amount may, subject to
         the proviso to the first sentence of this Section 2.03(a), exceed such
         Bank's Commitment), the rate or rates of interest therefor (and
         whether reserves are included therein) and such Bank's Applicable

                 paragraph (ii) above) to be made by each Bank as part of such

                 Administrative Agent notice to that effect; provided, however,
                 that the aggregate amount of such offers accepted by the
                 Borrower shall be equal at least to $10,000,000 or an integral
                 multiple of $5,000,000 in excess thereof.  Each such notice of
                 competitive bid acceptance/rejection (a "Competitive Bid
                 Accept/Reject Letter") from the Borrower shall be in a form
                 substantially similar to Exhibit A-5.

                 (iv)  If the Borrower notifies the Administrative Agent that
         such Competitive Borrowing is canceled pursuant to paragraph (iii)(A)
         above, the Administrative Agent shall give prompt notice (by cable or
         telecopy) thereof to the Banks, and such Competitive Borrowing shall
         not be made.

                 (v)  If the Borrower accepts one or more of the offers made by
         any Bank or Banks pursuant to paragraph (iii)(B) above, such offer or
         offers and the Notice of Competitive Borrowing in respect thereof
         shall constitute a supplement to this Agreement in respect of such
         Competitive Borrowing and the Competitive Advances made pursuant
         thereto, and the  Administrative Agent shall in turn promptly notify
         (A) each Bank that has made an offer as described in paragraph (ii)
         above of the date and aggregate amount of such Competitive Borrowing,
         the interest rate thereon, and whether or not any offer or offers made
         by such Bank pursuant to paragraph (ii) above have been accepted by
         the Borrower, and (B) each Bank that is to make a Competitive Advance
         as part of such Competitive Borrowing (a "Participating Bank" as to
         such Competitive Borrowing) of the amount of each Competitive Advance
         to be made by such Bank as part of such Competitive Borrowing and the
         maturity date for the repayment of each such Competitive Advance
         (together with a confirmation of the Administrative Agent's
         understanding of the interest rate and any other terms applicable to
         each such Competitive Advance; the Administrative Agent shall assume,
         unless notified by such Bank to the contrary, that its understanding
         of such information is correct).  Each such Participating Bank shall,
         before 12:00 noon (New York City time) on the date of such Competitive
         Borrowing specified in the notice received from the Administrative
         Agent pursuant to clause (A) of the preceding sentence, make available
         for the account of its Applicable Lending Office to the Administrative
         Agent (at its address referred to in Section 8.02) such Bank's portion
         of such Competitive Borrowing, in same-day funds.  Upon fulfillment of
         the applicable conditions set forth in Article III and after receipt
         by the Administrative Agent of such funds, the Administrative Agent
         will make such funds available to the Borrower at the Administrative
         Agent's aforesaid address.  Promptly after each Competitive Borrowing,
         the Administrative Agent will notify each Bank of the amount of the
         Competitive Borrowing, such Bank's Competitive Reduction resulting
         therefrom, and the date upon which such Competitive Reduction
         commenced and is anticipated to terminate.

                 (b)  Within the limits and on the conditions set forth in this
Section 2.03, the Borrower may from time to time borrow under this Section
2.03, repay pursuant to Section 2.07(b), prepay under Section 2.07(c) and
reborrow under this Section 2.03.

                 SECTION 2.04.  Conversion and Continuation of Contract
Borrowings.  (a)  The Borrower shall have the right at any time upon prior
irrevocable notice to the Administrative Agent (i) not later than 12:00 noon
(New York City time), one Business Day prior to conversion, to convert any
Borrowing consisting of Eurodollar Rate Contract Advances into a Borrowing
consisting of Alternate Base Rate Advances, (ii) not later than 10:00 a.m. (New
York City time), three Business Days prior to conversion or continuation, to
convert any Borrowing consisting of Alternate Base Rate Advances into a
Borrowing consisting of Eurodollar Rate Contract Advances or to continue any
Borrowing consisting of Eurodollar Rate Contract Advances for an additional
Interest Period and (iii) not later than 10:00 a.m. (New York City time), three
Business Days prior to conversion, to convert the Interest

                                                                              15

Period with respect to any Borrowing consisting of Eurodollar Rate Contract
Advances to another permissible Interest Period, subject in each case to the
following:

                 (i) each conversion or continuation shall be made pro rata
         among the Banks in accordance with the respective principal amounts of
         the Advances comprising the converted or continued Contract Borrowing;

                 (ii) if less than all the outstanding principal amount of any
         Contract Borrowing shall be converted or continued, the aggregate
         principal amount of such Contract Borrowing converted or continued
         shall be in an amount of $10,000,000 or an integral multiple of
         $5,000,000 in excess thereof;

                 (iii) accrued interest on an Advance (or portion thereof)
         being converted shall be paid by the Borrower at the time of
         conversion;

                 (iv) if any Borrowing consisting of Eurodollar Rate Contract
         Advances is converted at a time other than at the end of the Interest
         Period applicable thereto, the Borrower shall pay, upon demand, any
         amounts due to the Banks pursuant to Section 8.04(b) as a result of
         such conversion;

                 (v) any portion of a Contract Borrowing maturing or required
         to be repaid in less than one month may not be converted into or
         continued as a Borrowing consisting of Eurodollar Rate Contract
         Advances;

                 (vi) any portion of a Borrowing consisting of Eurodollar Rate
         Contract Advances which cannot be converted into or continued as such
         by reason of clause (v) above shall be automatically converted at the
         end of the Interest Period in effect for such Borrowing into a
         Borrowing consisting of Alternate Base Rate Advances; and

                 (vii) no Interest Period may be selected for any Borrowing
         consisting of Eurodollar Rate Contract Advances that would end later
         than the Maturity Date.

                 (b)  Each notice pursuant to clause (a) of this Section shall
be irrevocable and shall refer to this Agreement and specify (i) the identity
and amount of the Contract Borrowing that the Borrower requests be converted or
continued, (ii) whether such Contract Borrowing is to be converted to or
continued as a Borrowing consisting of Eurodollar Rate Contract Advances or
Alternate Base Rate Advances, (iii) if such notice requests a conversion, the
date of such conversion (which shall be a Business Day), and (iv) if such
Contract Borrowing is to be converted to or continued as a Borrowing consisting
of Eurodollar Rate Contract Advances, the Interest Period with respect thereto.
If no Interest Period is specified in any such notice with respect to any
conversion to or continuation as a Borrowing consisting of Eurodollar Rate
Contract Advances, the Borrower shall be deemed to have selected an Interest
Period of one month's duration.  The Administrative Agent shall advise the
other Banks of any notice given pursuant to this Section 2.04(b) and of each
Bank's portion of any converted or continued Contract Borrowing.  If the
Borrower shall not have given notice in accordance with this Section 2.04(b) to
continue any Contract Borrowing into a subsequent Interest Period (and shall
not otherwise have given notice in accordance with this Section 2.04 to convert
such Contract Borrowing), such Contract Borrowing shall, at the end of the
Interest Period applicable thereto (unless repaid pursuant to the terms
hereof), automatically be continued into a new Interest Period as a Borrowing
consisting of Alternate Base Rate Advances.

                 SECTION 2.05.  Fees.  (a)  Facility Fees.  Borrower shall pay
to each Bank, through the Administrative Agent, a facility fee (the "Facility
Fee") on the average daily amount of the Commitment of such Bank (whether used
or unused) (or, after such Bank's Commitment has terminated, on the outstanding
principal amount of Contract Advances made by such Bank) for the period from
and including the Closing Date up to, but excluding, the later of the Maturity
Date and the date of repayment of all outstanding Contract Advances, at a rate
per annum equal to the Applicable Margin for Facility Fees.  Accrued Facility
Fees shall be payable in arrears,

                                                                              16

commencing on the last day of the calendar quarter in which the Closing Date
occurs, and thereafter, quarterly on the last day of each March, June,
September and December and on the Maturity Date; provided that any Facility
Fees accruing after the Termination Date shall be payable contemporaneously
with accrued interest on the Contract Advances on which such Facility Fees have
accrued.

                 (b)  Fees of Administrative Agent.  Borrower shall pay to
Administrative Agent, solely for its own account, the fees described in the
separate letter agreement dated September 2, 1998, between Borrower and
Administrative Agent on the dates specified therein.

                 SECTION 2.06.  Reduction or Termination of the Commitments.
(a)  Unless previously terminated, the Commitments shall terminate on the
Termination Date.

                 (b)  The Borrower shall have the right, upon at least three
Business Days' irrevocable notice to the Administrative Agent, to terminate in
whole or reduce ratably in part the respective Commitments of the Banks;
provided, however, that (i) each partial reduction shall be in the aggregate
amount of $10,000,000 or in an integral multiple of $5,000,000 in excess
thereof, and (ii) no such termination or reduction shall be made which would
reduce the Commitments to an amount less than the aggregate outstanding
principal amount of the Advances.  The Administrative Agent shall promptly
thereafter notify each Bank of such termination or reduction.

                 SECTION 2.07.  Repayment of Advances; Prepayment.  (a)  The
Borrower shall repay to the Administrative Agent for the account of each Bank
the principal amount of each Contract Advance made by each Bank on the Maturity
Date.

                 (b)  The Borrower shall repay to the Administrative Agent, for
the account of each Participating Bank which has made a Competitive Advance, on
the maturity date of each Competitive Advance (such maturity date being that
specified by the Borrower for repayment of such Competitive Advance in the
Notice of Competitive Borrowing delivered with respect thereto) the then unpaid
principal amount of such Competitive Advance.

                 (c)  The Borrower may, on notice given to the Administrative
Agent (i) in the case of Alternate Base Rate Advances, not later than 11:00
a.m. (New York City time) one Business Day prior to the day of the proposed
prepayment, and (ii) in the case of Eurodollar Rate Contract Advances, not
later than 11:00 a.m. (New York City time) on the third Business Day prior to
the day of the proposed prepayment, stating the proposed date and aggregate
principal amount of the prepayment, and if such notice is given, the Borrower
shall, prepay the outstanding principal amounts of the Contract Advances
constituting part of the same Contract Borrowing in whole or ratably in part;
provided, however, that any such partial prepayment shall be in an aggregate
principal amount not less than $10,000,000, or in an integral multiple of
$5,000,000 in excess thereof.  The Borrower may not prepay any principal amount
of any Competitive Advance unless the Participating Bank making such
Competitive Advance shall have expressly agreed thereto.  The Administrative
Agent shall promptly notify each Bank of any prepayments pursuant to this
Section 2.07(c) promptly after any such prepayment.  The Borrower shall have no
right to prepay any principal amount of any Advance except as expressly set
forth in this Section 2.07.

                 (d)  On the date of any reduction or termination of the
Commitments, the Borrower shall pay or prepay so much of the Contract Advances
(other than Term Advances) as shall be necessary in order that the aggregate
principal amount of outstanding Advances (other than Term Advances) shall not
exceed the Commitments after giving effect to such reduction.  In the event
that, after giving effect to the prepayment of Contract Advances pursuant to
this paragraph, there remain outstanding Competitive Advances in a principal
amount greater than the Commitments, the Borrower shall not be required to
prepay such Competitive Advances unless Banks holding such Competitive Advances
request prepayment, in which event the Borrower shall prepay such Competitive
Advances; provided that the Borrower shall not be required to so prepay
Competitive Advances after the outstanding principal amount of Competitive
Advances has been reduced to the amount of the Commitments.

                 (e)  Any prepayment of Eurodollar Rate Contract Advances
pursuant to any paragraph of this Section shall be subject to the provisions of
Section 8.04(b) hereof.

                 SECTION 2.08.  Interest.  The Borrower shall pay interest on
each Advance made by each Bank from the date of such Advance until paid in
full, at the following rates per annum:

                 (a)  Contract Advances.  If such Advance is a Contract
         Advance, the Applicable Rate from time to time for such Contract
         Advance from the date of such Advance until the last day of the last
         Interest Period therefor, payable on the last day of each Interest
         Period and, in the case of any Interest Period longer than three
         months, on the last day of such three-month period, as the case may
         be.

                 (b)  Competitive Advances.  If such Advance is a Competitive
         Advance, a rate per annum equal at all times from the date of such
         Advance until the maturity thereof to the rate of interest for such
         Competitive Advance specified by the Participating Bank making such
         Competitive Advance in its Competitive Bid with respect thereto
         delivered pursuant to Section 2.03(a)(ii) above, payable on the
         proposed maturity date specified by the Borrower for such Competitive
         Advance in the related Notice of Competitive Borrowing delivered
         pursuant to Section 2.03(a)(i) above; provided that in the case of
         Advances with maturities of greater than three months, interest shall
         be payable at the end of each three-month period for such Advance.

                 (c)  Default Amounts.  In the case of any past-due amounts of
         the principal of, or (to the fullest extent permitted by law) interest
         on, any Advance, from the date such amount becomes due until paid in
         full, payable on demand, a rate per annum equal at all times to 2%
         above the Alternate Base Rate (or the Eurodollar Rate in the case of
         any outstanding Eurodollar Rate Advances until the end of their
         respective Interest Periods) in effect from time to time.

                 SECTION 2.09.  Alternate Rate of Interest.  If Banks having
more than 66-2/3% of the sum of the Commitments and the Term Advances shall, at
least one Business Day before the date of any requested Borrowing (including
any requested conversion or continuation of any Borrowing), notify the
Administrative Agent that the Eurodollar Rate for any Eurodollar Rate Advances
comprising such Borrowing will not adequately reflect the cost to such Banks of
making or funding their respective Advances for such Borrowing, the right of
the Borrower to select Advances of such Type for such Borrowing or any
subsequent Borrowing shall be suspended until the Administrative Agent shall
notify the Borrower and the Banks that the circumstances causing such
suspension no longer exist, and (a) any request by the Borrower for a
Eurodollar Rate Competitive Advance shall be of no force and effect and shall
be denied by the Administrative Agent and (b) any request by the Borrower for a
Eurodollar Rate Contract Advance shall be deemed to be a request for an
Alternate Base Rate Advance.

                 SECTION 2.10.  Optional Extension of Termination Date.  (a)
Optional Extension Procedures.  The Borrower may, upon notice (by telephone
(confirmed in writing promptly thereafter) or telecopy) received by the
Administrative Agent (which shall advise each Bank thereof as soon as
practicable thereafter) not earlier than 60 days and not later than 50 days
prior to the initial Termination Date, request (an "Extension Request") that
the Banks extend the Termination Date for an additional 364 days from the
initial Termination Date.

                 (i)  Banks' Response to Extension Request.  The Banks may, at
         their option, accept or reject such Extension Request by giving
         written notice to Administrative Agent delivered no earlier than 30
         days prior to (but no later than 20 days prior to) the initial
         Termination Date (the "Response Date").  If any Bank shall fail to
         give such notice to Administrative Agent by the Response Date, such
         Bank shall be deemed to have rejected the requested extension.  If the
         Extension Request is not consented to by Banks holding at least 51% of
         the Commitments by the Response Date, the Extension Request will be
         rejected, and the Termination Date will not be extended.  If the Banks
         holding at least 51% of the Commitments consent to the Extension
         Request by the Response Date, the Termination Date for those Banks
         consenting to the extension (for purposes of this Section 2.10(a), the
         "Accepting Banks") shall be automatically extended to the date which
         is the 364th day after the initial Termination Date.

                                                                              18

                 (ii)  Additional Procedures To Extend the Rejected Amount.  If
         the Extension Request is consented to by Banks holding not less than
         51% of the Commitments, but fewer than all Banks (any Bank not
         consenting to the Extension Request being referred to as a "Rejecting
         Bank"), then Administrative Agent shall, within 48 hours of making
         such determination, notify the Accepting Banks and Borrower of the
         aggregate Commitments held by the Rejecting Banks (the "Rejected
         Amount").  Each Accepting Bank shall have the right, but not the
         obligation, to elect to increase its respective Commitment by an
         amount not to exceed the Rejected Amount, which election shall be made
         by notice from each Accepting Bank to the Administrative Agent given
         not later than five days after the date notified by Administrative
         Agent, specifying the amount of such proposed increase in such
         Accepting Bank's Commitment.  If the aggregate amount of the proposed
         increases in the Commitments of all Accepting Banks making such an
         election does not equal or exceed the Rejected Amount, then Borrower
         shall have the right to add one or more financial institutions (which
         are not Rejecting Banks and which are Eligible Assignees) as Banks
         (each a "Purchasing Bank") to replace such Rejecting Banks, which
         Purchasing Banks shall have aggregate Commitments not greater than
         those of the Rejecting Banks (less any increases in the Commitments of
         Accepting Banks, as described in the following clause (iii)).  The
         transfer of Commitments and outstanding Borrowings from Rejecting
         Banks to Purchasing Banks or Accepting Banks shall take place (on or
         prior to the initial Termination Date) on the effective date of, and
         pursuant to the execution, delivery and acceptance of, an Assignment
         and Acceptance in accordance with the procedures set forth in Section
         8.07.

                 (iii)  Adjustments to, and Terminations of, Commitments.  (A)
         If less than 100% of the Commitments are extended (whether by virtue
         of Borrower's failure to request an extension of the total Commitments
         or by virtue of any Bank not consenting to any Extension Request),
         then the Commitments shall automatically be reduced on the initial
         Termination Date by an amount equal to (as the case may be) (i) the
         portion of the Commitments not requested to be extended by Borrower in
         its Extension Request or (ii) the amount of the Rejected Amount (to
         the extent not replaced by Accepting Banks or Purchasing Banks
         pursuant to the procedures set forth in the foregoing Section
         2.10(a)(ii)).  Notwithstanding the foregoing, each Rejecting Bank's
         outstanding Contract Advances (after giving effect to the replacement
         of the Rejected Amount by Accepting Banks or Purchasing Banks pursuant
         to Section 2.10(a)(ii)) may, at the Borrower's option, be continued as
         Term Advances as provided in Section 2.18.

                 (B)  If the aggregate amount of the proposed increases in the
         Commitments of all Accepting Banks making an election to increase
         their respective Commitments is in excess of the Rejected Amount, then

                          (i) the Rejected Amount shall be allocated pro rata
                 among such Accepting Banks based on the respective amounts of
                 the proposed increases to Commitments elected by such
                 Accepting Banks; and

                          (ii) the respective Commitments of each such
                 Accepting Bank shall be increased by the respective amount
                 allocated pursuant to clause (i) of this Section
                 2.10(a)(iii)(B), such that, after giving effect to the
                 approved extensions and all such terminations and increases,
                 no reduction will occur in the aggregate amount of the
                 Commitments (subject to Section 2.06(c)).

                 (C)  If the aggregate amount of the proposed increases to the
         Commitments of all Accepting Banks making such an election to so
         increase their respective Commitments equals the Rejected Amount, then
         the respective Commitments of such Accepting Banks shall be increased
         by the respective amounts of their proposed increases, such that,
         after giving effect to the approved extensions and all such
         terminations and increases, no reduction will occur in the aggregate
         amount of the Commitments (subject to Section 2.06(c)).

                 (D)  If the aggregate amount of the proposed increases to the
         Commitments of all Accepting Banks making such an election is less
         than the Rejected Amount, then

                          (i) the respective Commitments of each such Accepting
                 Bank shall be increased by the respective amount of its
                 proposed increase; and

                          (ii) the amount of the Commitments shall be reduced
                 in the amount of the Rejected Amount (to the extent not
                 replaced by the Accepting Banks or the Purchasing Banks, if
                 any).

                 (E)  Any reduction or termination of Commitments required by
         this Section shall be effective on the initial Termination Date
         immediately prior to determining whether any further reduction of
         Commitments is required by Section 2.06(c).

                 (b)  Acknowledgments Regarding Obligations To Renew.  Borrower
acknowledges that (i) neither Administrative Agent nor any Bank has made any
representations to Borrower regarding its intent to agree to any extensions set
forth in this Section and (ii) neither Administrative Agent nor any Bank shall
have any obligation to extend the Termination Date.

                 (c)  Payment to Rejecting Banks.  If, after giving effect to
any transfer of a Rejecting Bank's Commitment to an Accepting Bank or a
Purchasing Bank under Section 2.10(a)(ii) above, there are any amounts, other
than Contract Advances continued as Term Advances pursuant to Section 2.18 (and
accrued interest thereon), owed by Borrower to such Rejecting Bank under the
Loan Papers, then such amount is due and payable by Borrower to such Rejecting
Bank on the initial Termination Date.

                 SECTION 2.11.  Increased Costs; Increased Capital.  (a)  If
due to either (i) the introduction of or any change after the date hereof
(other than any change by way of imposition or increase of reserve requirements
included in the Eurodollar Rate Reserve Percentage) in or in the interpretation
of any law or regulation or (ii) the compliance with any guideline or request
received from any central bank or other governmental authority after the date
hereof (whether or not having the force of law), there shall be any increase in
the cost to any Bank of agreeing to make or making, funding, or maintaining
Eurodollar Rate Advances, then the Borrower shall from time to time, upon
demand by such Bank (with a copy of such demand to the Administrative Agent),
pay to the Administrative Agent for the account of such Bank additional amounts
sufficient to compensate such Bank for such increased cost.  Increased costs
shall not include income, stamp, or other taxes, imposts, duties, charges,
fees, deductions, or withholdings imposed, levied, collected, withheld, or
assessed by the United States of America or any political subdivision or taxing
authority thereof or therein (including Puerto Rico) or of the country in which
any Bank's principal office or Applicable Lending Office may be located or any
political subdivision or taxing authority thereof or therein.  Each Bank agrees
that, upon the occurrence of any event giving rise to a demand under this
Section 2.11(a) with respect to the Eurodollar Lending Office of such Bank, it
will, if requested by the Borrower and to the extent permitted by law or the
relevant governmental authority, endeavor in good faith and consistent with its
internal policies to avoid or minimize the increase in costs resulting from
such event by endeavoring to change its Eurodollar Lending Office; provided,
however, that such avoidance or minimization can be made in such a manner that
such Bank, in its sole determination, suffers no economic, legal, or regulatory
disadvantage.  A certificate as to the amount of and specifying in reasonable
detail the basis for such increased cost, submitted to the Borrower and the
Administrative Agent by such Bank, shall constitute such demand and shall, in
the absence of manifest error, be conclusive and binding for all purposes.

                 (b)  If either (i) the introduction after the date hereof of,
or any change after the date hereof in or in the interpretation of, any law or
regulation or (ii) the compliance by any Bank with any guideline or request
received from any central bank or other governmental authority after the date
hereof (whether or not having the





<PAGE>   24
                                                                              20

force of law), affects or would affect the amount of capital required or
expected to be maintained by such Bank or any corporation controlling such Bank
and such Bank determines that the amount of such capital is increased by or
based upon the existence of its Advances or Commitment, then the Borrower
shall, from time to time, upon demand by such Bank (with a copy of such demand
to the Administrative Agent), immediately pay to the Administrative Agent for
the account of such Bank additional amounts sufficient to compensate such Bank
to the extent that such Bank determined such increase in capital to be
allocable to the existence of such Bank's Advances or Commitment.  A
certificate as to the amount of such increased capital and specifying in
reasonable detail the basis therefor, submitted to the Borrower and the
Administrative Agent by such Bank, shall constitute such demand and shall, in
the absence of manifest error, be conclusive and binding for all purposes.
Each Bank shall use all reasonable efforts to mitigate the effect upon the
Borrower of any such increased capital requirement and shall assess any cost
related to such increased capital on a nondiscriminatory basis among the
Borrower and other borrowers of such Bank to which it applies and such Bank
shall not be entitled to demand or be compensated for any increased capital
requirement unless it is, as a result of such law, regulation, guideline, or
request, such Bank's policy generally to seek to exercise such rights, where
available, against other borrowers of such Bank.

                 (c)  Notwithstanding the foregoing provisions of this Section
2.11, (i) the Borrower shall not be required to reimburse any Bank for any
increased costs incurred more than three months prior to the date that such
Bank notifies the Borrower in writing thereof and (ii) in the event any Bank
grants a participation or assignment in an Advance pursuant to Section 8.07,
the Borrower shall not be obligated to reimburse for increased costs with
respect to such Advance to the extent that the aggregate amount thereof exceeds
the aggregate amount for which the Borrower would have been obligated if such
Bank had not made such participation or assignment.

                 SECTION 2.12.  Additional Interest on Eurodollar Rate
Advances.  The Borrower shall pay to the Administrative Agent for the account
of each Bank any costs which such Bank determines are attributable to such
Bank's compliance with regulations of the Board requiring the maintenance of
reserves with respect to liabilities or assets consisting of or including
Eurocurrency Liabilities.  Such costs shall be paid to the Administrative Agent
for the account of such Bank in the form of additional interest on the unpaid
principal amount of each Eurodollar Rate Advance of such Bank, from the date of
such Advance until such principal amount is paid in full, at an interest rate
per annum equal at all times to the remainder obtained by subtracting (i) the
Eurodollar Rate for the applicable period for such Advance from (ii) the rate
obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus
the Eurodollar Rate Reserve Percentage of such Bank for such period, payable on
each date on which interest is payable on such Advance.  Such additional
interest shall be determined by such Bank and notified to the Borrower and the
Administrative Agent.  A certificate setting forth the amount of such
additional interest, submitted to the Borrower and the Administrative Agent by
such Bank, shall be conclusive and binding for all purposes, absent manifest
error.

                 SECTION 2.13.  Change in Legality.  If any Bank (as used in
this paragraph, a "Notifying Bank") shall, at least three Business Days before
the date of any requested Borrowing consisting of Eurodollar Rate Advances
notify the Administrative Agent that the introduction of or any change in or in
the interpretation of any law or regulation makes it unlawful, or that any
central bank or other governmental authority asserts that it is unlawful, for
such Notifying Bank or its Applicable Lending Office to perform its obligations
hereunder to make, fund or maintain Eurodollar Rate Advances hereunder, the
right of the Borrower to select Advances of such Type from such Notifying Bank
for such Borrowing or any subsequent Borrowing shall be suspended until such
Notifying Bank shall notify the Administrative Agent that the circumstances
causing such suspension no longer exist; provided that during the period when
such obligation of such Notifying Bank is suspended, any Borrowing consisting
of Eurodollar Rate Advances shall not exceed the Commitments of the other Banks
less the aggregate amount of any Advances (including Competitive Advances) then
outstanding, and shall be made by the other Banks pro rata according to their
respective Commitments; provided further if any such request for a Eurodollar
Rate Advance is made in respect of a Borrowing that includes a Term Advance of
the Notifying Bank, then the immediately preceding proviso shall not apply to
such Term Advance and (i) such Term Advance shall remain outstanding, (ii) any
request for the conversion or continuation of all or any portion of such
Notifying Bank's Term





<PAGE>   25
                                                                              21

Advance as a Eurodollar Rate Advance shall be ineffective (but shall be
effective for the other Term Advances included in such Borrower) and (iii) such
Notifying Bank's Term Advance included in such Borrowing shall continue as an
Alternate Base Rate Advance.

                 SECTION 2.14.  Payments and Computations.  (a)  The Borrower
shall make each payment hereunder from a bank account of the Borrower located
in the United States not later than 11:00 a.m. (New York City time) on the day
when due in U.S. dollars to the Administrative Agent at its address referred to
in Section 8.02 in same-day funds.  The Administrative Agent will promptly
thereafter cause to be distributed like funds to the Banks entitled thereto for
the account of their respective Applicable Lending Offices, in each case to be
applied in accordance with the terms of this Agreement.

                 (b)  All computations of interest based on the Alternate Base
Rate shall be made by the Administrative Agent on the basis of a year of 365 or
366 days, as the case may be, when determined by reference to the Prime Rate
and on the basis of a year of 360 days at all other times; and all computations
of fees and of interest based on the Eurodollar Rate or the Fixed Rate shall be
made by the Administrative Agent on the basis of a year of 360 days, in each
case for the actual number of days (including the first day but excluding the
last day) occurring in the period for which such interest or fees are payable.
Each determination by the Administrative Agent of an interest rate hereunder
shall be conclusive and binding for all purposes, absent manifest error.

                 (c)  Whenever any payment hereunder shall be stated to be due
on a day other than a Business Day, such payment shall be made on the next
succeeding Business Day, and such extension of time shall be included in the
computation of payment of interest or fees, as the case may be; provided,
however, that if such extension would cause payment of interest on or principal
of Eurodollar Rate Advances to be made in the next following calendar month,
such payment shall be made on the next preceding Business Day.

                 (d)  Unless the Administrative Agent shall have received
notice from the Borrower prior to the date on which any payment is due to the
Banks hereunder that the Borrower will not make such payment in full, the
Administrative Agent may assume that the Borrower has made such payment in full
to the Administrative Agent on such date and the Administrative Agent may, in
reliance upon such assumption, cause to be distributed to each Bank on such due
date an amount equal to the amount then due such Bank.  If and to the extent
the Borrower shall not have so made such payment in full to the Administrative
Agent, each Bank shall repay to the Administrative Agent forthwith on demand
such amount distributed to such Bank together with interest thereon, for each
day from the date such amount is distributed to such Bank until the date such
Bank repays such amount to the Administrative Agent, at the Federal Funds
Effective Rate.

                 (e)  Each Bank shall maintain on its books a loan account in
the name of the Borrower in which shall be recorded all Advances made by such
Bank to the Borrower, the interest rate, and the maturity date of each such
Advance and all payments of principal and interest made by the Borrower with
respect to such Advances.  The obligation of the Borrower to repay the Advances
made by each Bank and to pay interest thereon shall be evidenced by the entries
from time to time made in the loan account of such Bank maintained pursuant to
this Section 2.14(e); provided that the failure to make an entry with respect
to an Advance shall not affect the obligations of the Borrower hereunder with
respect to such Advance.  In case of any dispute, action or proceeding relating
to any Advance, the entries in such loan account shall be prima facie evidence
of the amount of such Advance and of any amounts paid or payable with respect
thereto.

                 (f)  The Administrative Agent shall maintain on its books a
set of accounts in which shall be recorded all Advances made by the Banks to
the Borrower, the interest rates, and maturity dates of such Advances and all
payments of principal and interest made thereon.  In case of any discrepancy
between the entries in the Administrative Agent's books and the entries in any
Bank's books, such Bank's records shall be considered correct, in the absence
of manifest error.

                                                                              22

                 SECTION 2.15.  Taxes on Payments.  (a)  All payments made by
the Borrower under this Agreement shall be made free and clear of, and without
reduction for or on account of, any income, stamp, or other taxes, imposts,
duties, charges, fees, deductions, or withholdings, imposed, levied, collected,
withheld, or assessed by the United States of America (or by any political
subdivision or taxing authority thereof or therein) as a result of (i) the
introduction after the date hereof of any law, regulation, treaty, directive,
or guideline (whether or not having the force of law), or (ii) any change after
the date hereof in any law, regulation, treaty, directive, or guideline
(whether or not having the force of law), or (iii) any change after the date
hereof in the interpretation or application of any law, regulation, treaty,
directive, or guideline (whether or not having the force of law), or (iv) any
such taxes, imposts, duties, charges, fees, deductions, or withholdings being
imposed, levied, collected, withheld, or assessed at a greater rate than the
rate that would have been applicable had such an introduction or change not
been made, but only to the extent of the increase in such rate ("Withholding
Taxes").  If any Withholding Taxes are required to be withheld from any amounts
payable to or for the account of any Bank hereunder, the amounts so payable to
or for the account of such Bank shall be increased to the extent necessary to
yield to such Bank (after payment of all Withholding Taxes) interest or any
such other amounts payable hereunder at the rates or in the amounts payable to
or for the account of such Bank under this Agreement prior to such introduction
or change.  Whenever any Withholding Tax is payable by the Borrower, as
promptly as possible thereafter, the Borrower shall send to the Administrative
Agent, for the account of such Bank, a certified copy of an original official
receipt showing payment thereof.  If the Borrower fails to pay any Withholding
Taxes when due to the appropriate taxing authority or fails to remit to the
Administrative Agent, for the account of any Bank the required receipts or
other required documentary evidence, the Borrower shall indemnify such Bank or
the Administrative Agent for any incremental taxes, interest, or penalties
(including any Withholding Taxes imposed or asserted on or attributable to
amounts payable under this Section) that may become payable by such Bank or the
Administrative Agent as a result of any such failure.

                 (b)  At least four Business Days prior to the first Borrowing
or, if the first Borrowing does not occur within thirty days after the date of
execution of this Agreement, by the end of such thirty-day period, each Bank
that is organized outside the United States agrees that it will deliver to the
Borrower and the Administrative Agent two duly completed copies of United
States Internal Revenue Service Form 1001 (or such other documentation or
information as may, under applicable United States Federal income tax statutes
or regulations, be required in order to claim an exemption or reduction from
United States income tax withholding by reason of an applicable treaty with the
United States, such documentation or other information being hereafter referred
to as "Form 1001") or Form 4224 (or such other documentation or information as
may, under applicable United States Federal income tax statutes or regulations,
be required in order to claim an exemption from United States income tax
withholding for income that is effectively connected with the conduct of a
trade or business within the United States, such documentation or other
information being hereafter referred to as "Form 4224"), as the case may be, in
the case of a Bank claiming exemption from U.S. Federal withholding tax under
Section 871(h) or 881(c) of the Code with respect to payments of "portfolio
interest", a Form W-8, or any subsequent versions thereof or successors thereto
(and, if such Bank delivers a Form W-8, a certificate representing that such
Bank is not a bank for purposes of Section 881(c) of the Code, is not a
10-percent shareholder of the Borrower (within the meaning of Section
871(h)(3)(B) of the Code) and is not a controlled foreign corporation related
to the Borrower (within the meaning of Section 864(d)(4) of the Code)),
indicating in each case that such Bank is either entitled to receive payments
under this Agreement without deduction or withholding of any United States
Federal income taxes or, as the case may be, is subject to such limited
deduction or withholding.  Each Bank which delivers to the Borrower and the
Administrative Agent such forms pursuant to the next preceding sentence further
undertakes to deliver to the Borrower and the Administrative Agent two further
copies of such forms, or successor applicable form or certificate, as the case
may be, as and when the previous form filed by it hereunder shall expire or
shall become incomplete or inaccurate in any respect, unless in any of such
cases an event has occurred prior to the date on which any such delivery would
otherwise be required which renders such form inapplicable.

                 (c)  If at any time any Bank by reason of payment by the
Borrower of any Withholding Taxes obtains a credit against, or return or
reduction of, any tax payable by it, or any other currently realized tax
benefit, which it would not have enjoyed but for such payment ("Tax Benefit"),
such Bank shall thereupon pay to the





<PAGE>   27
                                                                              23

Borrower the amount which such Bank shall certify to be the amount that after
payment, will leave such Bank in the same economic position it would have been
in had it received no such Tax Benefit ("Equalization Amount"); provided,
however, that if such Bank shall subsequently determine that it has lost the
benefit of all or a portion of such Tax Benefit, the Borrower shall promptly
remit to such Bank the amount certified by such Bank to be the amount necessary
to restore such Bank to the position it would have been in if no payment had
been made pursuant to this Section 2.15(c); provided further, however, that if
such Bank shall be prevented by applicable law from paying the Borrower all or
any portion of the Equalization Amount owing to the Borrower such payment need
not be made to the extent such Bank is so prevented and the amount not paid
shall be credited to the extent lawful against future payment owing to such
Bank; provided further, however, that the aggregate of all Equalization Amounts
paid by any Bank shall in no event exceed the aggregate of all amounts paid by
the Borrower to such Bank in respect of Withholding Taxes plus, in the case of
a Tax Benefit that occurs by reason of a refund interest actually received from
the relevant taxing authority with respect to such refund.  A certificate
submitted in good faith by the Bank pursuant to this Section 2.15(c) shall be
deemed conclusive absent manifest error.

                 (d)  In the event a Bank shall become aware that the Borrower
is required to pay any additional amount to it pursuant to Section 2.15(a),
such Bank shall promptly notify the Administrative Agent and the Borrower of
such fact and shall use reasonable efforts, consistent with legal and
regulatory restrictions, to change the jurisdiction of its Applicable Lending
Office if the making of such change (i) would avoid the need for, or reduce the
amount of, any such additional amounts that may thereafter accrue, (ii) would
not, in the good faith determination of such Bank, be disadvantageous for
regulatory or competitive reasons to such Bank, and (iii) would not require
such Bank to incur any cost or forego any economic advantage for which the
Borrower shall not have agreed to reimburse and indemnify such Bank.

                 (e)  Notwithstanding the foregoing provisions of this Section
2.15, in the event any Bank grants a participation in any Advance pursuant to
Section 8.07, the Borrower shall not be obligated to pay any taxes, imposts,
duties, charges, fees, deductions, or withholdings to the extent that the
aggregate amount thereof exceeds the aggregate amount for which the Borrower
would have been obligated if such Bank had not granted such participation.

                 SECTION 2.16.  Sharing of Payments, Etc.  If any Bank shall
obtain any payment (whether voluntary, involuntary, through the exercise of any
right of setoff or otherwise) on account of the Contract Advances made by it
(other than pursuant to Sections 2.11, 2.15, 2.17, 8.04, or 8.07(g) hereof) in
excess of its ratable share of payments on account of the Contract Advances
obtained by all the Banks, then such Bank shall forthwith purchase from the
other Banks through the Administrative Agent such participations in the
Contract Advances made by them as shall be necessary to cause such purchasing
Bank to share the excess payment ratably with each of them; provided, however,
that, if all or any portion of such excess payment is thereafter recovered from
such purchasing Bank, such purchase from each Bank shall be rescinded, and such
Bank shall repay to the purchasing Bank the purchase price to the extent of
such recovery, together with an amount equal to such Bank's ratable share
(according to the proportion that (i) the amount of such Bank's required
repayment bears to (ii) the total amount so recovered from the purchasing Bank)
of any interest or other amount paid or payable by the purchasing Bank in
respect of the total amount so recovered. The Borrower agrees that any Bank so
purchasing a participation from another Bank pursuant to this Section 2.16 may,
to the fullest extent permitted by law, exercise all its rights of payment
(including the right of setoff) with respect to such participation as fully as
if such Bank were the direct creditor of the Borrower in the amount of such
participation.

                 SECTION 2.17.  Removal of a Bank.  The Borrower shall have the
right, by giving at least 15 Business Days' prior notice in writing to the
affected Bank and the Administrative Agent, at any time when no Event of
Default and no event which with the passage of time or the giving of notice or
both would become an Event of Default has occurred and is then continuing, to
remove as a party hereto any Bank having a credit rating of C/D (or its
equivalent) or lower by Thomson BankWatch, Inc. (or any successor thereto),
such removal to be effective as of the date specified in such notice from the
Borrower (a "Removal Date"), which date, for any





<PAGE>   28
                                                                              24

Eurodollar Rate Contract Advance, shall be the last day of an Interest Period
and, for any Competitive Advance, shall be the maturity date of such
Competitive Advance; provided that no such Bank may be removed if it does not
have a Commitment at the time.  On any Removal Date, the Borrower shall repay
all the outstanding Advances (other than Term Advances, if any) of the affected
Bank applicable to such Removal Date, together with all accrued interest, fees,
and all other amounts owing hereunder to such Bank.  Upon each such Removal
Date and receipt of the related payment referred to above, the Commitment
relating to the Advances so paid on such Removal Date, together with all unused
Commitment, of such affected Bank shall terminate, and such Bank shall cease
thereafter to constitute a Bank hereunder (other than with respect to any Term
Advances of such Bank).  The Borrower shall have the right to offer to one or
more Banks the right to increase their Commitments up to, in the aggregate for
all such increases, the Commitment of any Bank which is removed pursuant to the
foregoing provisions of this Section 2.17 (such Commitment being herein called
an "Unallocated Commitment") effective on the relevant Removal Date, it being
understood that no Bank shall be obligated to increase its Commitment in
response to any such offer.  The Borrower shall also have the right to offer
all or any portion of an Unallocated Commitment to one or more Eligible
Assignees not parties hereto having a credit rating higher than C/D (or its
equivalent) by Thomson BankWatch, Inc. (or any successor thereto), and, upon
each such bank's acceptance of such offer and execution and delivery of an
instrument agreeing to the terms and conditions hereof (including, without
limitation, the provisions of Section 8.07 regarding Bank assignments), each
such bank shall become a Bank hereunder with a Commitment in an amount
specified in such instrument.  The obligations of the Borrower described in
Sections 2.11, 8.04, and 8.15 shall survive for the benefit of any Bank removed
pursuant to this Section 2.17 notwithstanding such removal.

                 SECTION 2.18.  Extension of Maturity Date.  (a) If the initial
Termination Date shall be extended pursuant to Section 2.10, then the initial
Maturity Date shall automatically be extended to the date 364 days after the
initial Termination Date (the "Extended Maturity Date").

                 (b)  If the initial Termination Date shall not be extended
pursuant to Section 2.10, then (unless an Event of Default has occurred and is
continuing) the Borrower may elect to extend the initial Maturity Date to the
Extended Maturity Date by delivering notice of such extension (a "Maturity Date
Extension Notice") to the Administrative Agent (which shall promptly deliver a
copy of such Maturity Date Extension Notice to each Bank) not later than 15
days prior to the Termination Date.  If a Maturity Date Extension Notice shall
be delivered in accordance with this paragraph, then (i) the initial Maturity
Date shall be automatically extended to the Extended Maturity Date, (ii) the
principal amount of all Contract Advances outstanding on the Termination Date
shall remain outstanding as term advances (the "Term Advances") which mature on
the Extended Maturity Date, (iii) all Competitive Advances shall be paid in
full on or prior to the Termination Date and (iv) all Commitments shall
terminate on the Termination Date.

                 (c)  If the initial Termination Date shall be extended
pursuant to Section 2.10, but there shall remain a Rejected Amount (after
giving effect to any replacements by Accepting Banks and Purchasing Banks
pursuant to Section 2.10), then (unless an Event of Default has occurred and is
continuing) the Borrower may elect to extend the initial Maturity Date with
respect to outstanding Contract Advances of Rejecting Banks to the Extended
Maturity Date by delivering a Maturity Date Extension Notice to the
Administrative Agent (which shall promptly deliver a copy of such Maturity Date
Extension Notice to the Rejecting Banks) not later than 15 days prior to the
initial Termination Date.  If a Maturity Date Extension Notice shall be
delivered in accordance with this paragraph, then (i) the Termination Date with
respect to the Commitments of the Accepting Banks and any Purchasing Banks
shall be extended in accordance with Section 2.10, (ii) the Commitments of the
Rejecting Banks (after giving effect to replacements by Accepting Banks and
Purchasing Banks pursuant to Section 2.10) shall terminate, (iii) the initial
Maturity Date shall be extended to the Extended Maturity Date, (iv) subject to
Section 2.07(e), the principal amount of all Contract Advances of the Rejecting
Banks outstanding on the initial Termination Date (after giving effect to
replacements by Accepting Banks and Purchasing Banks pursuant to Section 2.10)
shall remain outstanding as Term Advances which mature on the Extended Maturity
Date and (v) all Competitive Advances of Rejecting Banks shall be paid in full
on or prior to the initial Termination Date; provided that (A) Contract
Advances of Banks other then Rejecting Banks, including Contract Advances made
pursuant to





<PAGE>   29
                                                                              25

Section 2.01 after the initial Termination Date shall not be deemed Term
Advances and (B) the sum of the principal amount of the Term Advances and the
Commitments immediately after giving effect to the provisions of this Section
and Section 2.10 on the initial Termination Date, shall not exceed the
aggregate amount of Commitments immediately prior to giving effect to such
provisions on the initial Termination Date.

                 (d)  If any Contract Advance shall remain outstanding as a
Term Advance pursuant to paragraph (b) or (c) above, such Term Advance shall
continue to constitute a Contract Advance for all purposes of this Agreement.


                                  ARTICLE III

                             Conditions of Lending

until the date on which each of the following conditions is satisfied (or
waived in accordance with Section 8.01):

                 (a)  The Administrative Agent (or its counsel) shall have

         Agreement signed on behalf of such party or (ii) written evidence
         satisfactory to the Administrative Agent (which may include telecopy
         transmission of a signed signature page of this Agreement) that such
         party has signed a counterpart of this Agreement.

                 (b)  The Administrative Agent shall have received a favorable

         and dated the Closing Date) of (i) Joseph A. LaSala, Jr., counsel for
         the Borrower, substantially in the form of Exhibit C-1 and (ii) Morgan

         in the form of Exhibit C-2, in each case covering such other matters
         relating to the Borrower, the Loan Papers or the Transactions as the
         Majority Banks shall reasonably request.  The Borrower hereby requests
         such counsel to deliver such opinions.

                 (c)  The Administrative Agent shall have received such
         documents and certificates as the Administrative Agent or its counsel

         including, to the extent invoiced, reimbursement or payment of all
         out-of-pocket expenses required to be reimbursed or paid by the
         Borrower hereunder.

                 (f)  All consents and approvals required to be obtained from
         any governmental authority or other Person in connection with the
         Transactions shall have been obtained, except to the extent that
         failure to obtain any such consent or approval, individually or in the
         aggregate, could not reasonably be expected to have a material adverse
         effect on the business, assets, operations, financial condition or
         prospects of the Borrower and its Subsidiaries, taken as a whole.

                 (g)  The Previous Credit Agreements shall have been terminated
         and all amounts outstanding thereunder shall have been or shall
         simultaneously be repaid (or in the case of banker's acceptances
         listed on Schedule V hereto, shall be deemed to have been issued under
         the Credit Agreement described in clause (a) of the definition of
         "Other Credit Agreements"), except that the Credit Agreement referred
         to in clause (d)(i) of the definition of Previous Credit Agreements
         shall be terminated and all amounts outstanding thereunder shall be
         repaid on or prior to December 1, 1998.

                 (h)  There shall not be any litigation, administrative
         proceedings or other legal or regulatory actions pending or threatened
         which individually or in the aggregate (i) prevent or impose
         materially adverse conditions upon any of the Transactions or (ii)
         could reasonably be expected to have a material adverse effect on the
         business, assets, operations, financial condition or prospects of the
         Borrower and its Subsidiaries, taken as a whole.

                 (i)  The consummation of the Transactions shall not (i)
         violate any applicable law, statute, rule or regulation or (ii)
         conflict with, or result in a default under, or any right to terminate
         or renegotiate, any material Debt or contract of the Borrower or any
         of its Subsidiaries.

                 (j)  The Other Credit Agreements shall have become or shall
         simultaneously become effective.

The Administrative Agent shall notify the Borrower and the Banks of the Closing
Date, and such notice shall be conclusive and binding.  Notwithstanding the
foregoing, the obligations of the Banks to make Advances hereunder shall not
become effective unless each of the foregoing conditions is satisfied (or
waived pursuant to Section 8.01) at or prior to 3:00 p.m., New York City time,
on November 4, 1998 (and, in the event such conditions are not so satisfied or
waived, the Commitments shall terminate at such time).

                 SECTION 3.02.  Conditions Precedent to Each Borrowing.  The
obligation of each Bank to make an Advance in connection with any Borrowing
(including without limitation, the initial Borrowing) shall be subject to the
further conditions precedent that on the date of such Borrowing, (i)
Administrative Agent shall have received a Notice of Contract Borrowing or
Notice of Competitive Borrowing, executed and completed by a Financial Officer
of the Borrower, and (ii) the following statements shall be true (and each of
the giving of the applicable Notice of Contract Borrowing or Notice of
Competitive Borrowing and the acceptance by the Borrower of the proceeds of
such Borrowing shall constitute a representation and warranty by the Borrower
that on the date of such Borrowing such statements are true):

                 (a) the representations and warranties contained in Article IV
         (excluding for all Borrowings, other than the initial Borrowings,
         those contained in subsections (f), (j), (k) and (l) thereof) are
         correct on and as of the date of such Borrowing, before and after
         giving effect to such Borrowing and to the application of the proceeds
         therefrom, as though made on and as of such date; and

                 (b) no event has occurred and is continuing, or would result
         from such Borrowing or from the application of the proceeds therefrom,
         which constitutes an Event of Default.


                                   ARTICLE IV

                         Representations and Warranties

                 The Borrower represents and warrants as follows:

                 (a)  The Borrower is a corporation duly organized, validly
         existing and in good standing under the laws of the State of Utah.

                                                                              27

                 (b)  The Transactions are within the Borrower's corporate
         powers, have been duly authorized by all necessary corporate action,
         and do not contravene (i) the Borrower's charter or by-laws or (ii)
         any law or any contractual restriction binding on or affecting the
         Borrower.

                 (c)  No authorization or approval or other action by, and no
         notice to or filing with, any governmental authority, regulatory body,
         or other Person is required for the due execution, delivery and
         performance by the Borrower of this Agreement and the consummation by
         the Borrower of the Transactions, except such as have been duly
         obtained or made and are in full force and effect.

                 (d)  This Agreement is the legal, valid and binding obligation
         of the Borrower enforceable against the Borrower in accordance with
         its terms.

                 (e)  (i)  The statement of consolidated financial position of
         the Borrower and its consolidated Subsidiaries as of December 31,
         1997, and the related statements of consolidated income and
         consolidated changes in common stockholders' equity of the Borrower
         and its consolidated Subsidiaries for the fiscal year then ended,
         copies of which have been furnished to each Bank, fairly present the
         financial condition of the Borrower and its consolidated Subsidiaries
         as at such date and present the financial condition of the Borrower
         and its consolidated Subsidiaries for the period ended on such date,
         all in accordance with generally accepted accounting principles
         consistently applied.

                 (ii)  The statement of consolidated financial position of the
         Borrower and its consolidated Subsidiaries as of June 30, 1998, and
         the related statements of consolidated income and consolidated changes
         in common stockholders' equity of the Borrower and its consolidated
         Subsidiaries for the fiscal quarter then ended, copies of which have
         been furnished to each Bank, fairly present the financial condition of
         the Borrower and its consolidated Subsidiaries as at such date and
         present the financial condition of the Borrower and its consolidated
         Subsidiaries for the period ended on such date, all in accordance with
         generally accepted accounting principles consistently applied, and
         since June 30, 1998, there has been no material adverse change in such
         condition or operations.

                 (f)  There is no pending or threatened action or proceeding
         affecting the Borrower or any of its consolidated Subsidiaries before
         any court, governmental agency or arbitrator, (i) which purports to
         affect the legality, validity or enforceability of the Transactions or
         (ii) except as set forth in public documents filed with the Securities
         and Exchange Commission or otherwise disclosed publicly on or prior to
         the Closing Date, which may be reasonably expected to materially
         adversely affect the financial condition or operations of the Borrower
         or any of its Subsidiaries, taken as a whole.

                 (g)  After applying the proceeds of each Advance, not more
         than 25% of the value of the assets of the Borrower and its
         Subsidiaries (as determined in good faith by the Borrower) that are
         subject to Section 5.02(a) will consist of or be represented by Margin
         Stock.

                 (h)  The Borrower is not engaged in the business of extending
         credit for the purpose of purchasing or carrying Margin Stock and no
         proceeds of any Advance will be used for any purpose which violates
         the provisions of the regulations of the Board.  If requested by any
         Bank or the Administrative Agent, the Borrower will furnish to the
         Administrative Agent and each Bank a statement in conformity with the
         requirements of Federal Reserve Form U-1 referred to in Regulation U,
         the statements made in which shall be such, in the opinion of each
         Bank, as to permit the transactions contemplated hereby in accordance
         with Regulation U.

                 (i)  No Termination Event has occurred nor is reasonably
         expected to occur with respect to any Plan which may materially
         adversely affect the financial condition or operations of the Borrower
         and its Subsidiaries, taken as a whole.  Neither the Borrower nor any
         of its ERISA Affiliates has incurred nor





<PAGE>   32
                                                                              28

         reasonably expects to incur any withdrawal liability under ERISA to
         any Multiemployer Plan which may reasonably be expected to materially
         adversely affect the financial condition or operations of the Borrower
         and its Subsidiaries, taken as a whole.  Schedule B (Actuarial
         Information) to the 1994 annual report (Form 5500 Series) with respect
         to each Plan, copies of which have been filed with the Internal
         Revenue Service and furnished to each Bank, is complete and accurate
         in all material respects and in all material respects fairly presents
         the funding status of each Plan.  No Reportable Event has occurred and
         is continuing with respect to any Plan which may materially adversely
         affect the financial condition or operations of the Borrower and its
         Subsidiaries, taken as a whole.

                 (j)  On the date of the initial Borrowing, and after giving
         effect to the Transactions, Borrower is Solvent.  For purposes hereof,
         "Solvent" means, as to a Person, that (i) the aggregate fair market
         value of such Person's assets exceeds its liabilities (whether
         contingent, subordinated, unmatured, unliquidated, or otherwise), (ii)
         such Person has sufficient cash flow to enable it to pay its Debts as
         they mature, and (iii) such Person does not have unreasonably small
         capital to conduct such Person's business.  In computing the amount of
         contingent liabilities at any time, for purposes of determining
         solvency, it is intended that such liabilities will be computed at the
         amount which, in light of all the facts and circumstances existing at
         such time, represents, the amount that can reasonably be expected to
         become an actual or matured liability.

                 (k)  Except as disclosed in public documents filed with the
         Securities and Exchange Commission or otherwise disclosed publicly on
         or prior to the Closing Date, neither Borrower nor any Restricted
         Subsidiary is a party to a material transaction with any of its
         Affiliates, other than transactions in the ordinary course of business
         and upon fair and reasonable terms not materially less favorable than
         the Borrower or such Restricted Subsidiary could obtain or could
         become entitled to in an arm's-length transaction with a Person that
         was not its Affiliate.

                 (l)  The proportion that the combined EBITDAX of the Borrower
         and the Principal Subsidiaries bears to the consolidated EBITDAX for
         the Borrower and its Subsidiaries is not less than 80%.

                 (m) Any reprogramming required to permit the proper
         functioning, in and following the year 2000, of (i) the Borrower's and
         its Subsidiaries' computer systems and (ii) equipment containing
         embedded microchips (including systems and equipment supplied by
         others) and the testing of all such systems and equipment, as so
         reprogrammed, will be completed by September 1, 1999.  The cost to the
         Borrower and the Subsidiaries of such reprogramming and testing and of
         the reasonably foreseeable consequences of year 2000 to the Borrower
         and its Subsidiaries (including, without limitation, reprogramming
         errors) will not, taken as a whole, result in an Event of Defaults or
         a material adverse effect on the Borrower and its Subsidiaries taken
         as a whole.  Except for such of the reprogramming referred to in the
         preceding sentence as may be necessary, the computer and management
         information systems of the Borrower and its Subsidiaries are and, with
         ordinary course upgrading and maintenance, will continue for the term
         of this Agreement to be, sufficient to permit the Borrower and its
         Subsidiaries to conduct their respective businesses without material
         adverse effect on the Borrower and its Subsidiaries taken as a whole.

                           Covenants of the Borrower

                 SECTION 5.01.  Affirmative Covenants.  So long as any Advance
shall remain unpaid or any Bank shall have any Commitment hereunder, the
Borrower will, and, in the case of Section 5.01(a), will cause its Subsidiaries
to, unless the Majority Banks shall otherwise consent in writing:

                 (a)  Keep Books; Corporate Existence; Maintenance of
Properties; Compliance with Laws; Insurance.

                          (i)   keep proper books of record and account, all in
                 accordance with generally accepted accounting principles;

                          (ii)  preserve and keep in full force and effect its
                 existence, and preserve and keep in full force and effect its
                 licenses, rights and franchises to the extent it deems
                 necessary to carry on its business;

                          (iii) maintain and keep, or cause to be maintained
                 and kept, its properties in good repair, working order and
                 condition, and from time to time make or cause to be made all
                 needful and proper repairs, renewals, replacements and
                 improvements, in each case to the extent it deems necessary to
                 carry on its business;

                          (iv)  use its reasonable efforts to comply in all
                 material respects with all material applicable statutes,
                 regulations, and orders of, and all material applicable
                 restrictions imposed by, any governmental agency in respect of
                 the conduct of its business and the ownership of its
                 properties, to the extent it deems necessary to carry on its
                 business, except such as are being contested in good faith by
                 appropriate proceedings;

                          (v) insure and keep insured its properties in such
                 amounts (and with such self insurance and deductibles) as it
                 deems necessary to carry on its business and to the extent
                 available on premiums and other terms which the Borrower or
                 any Subsidiary, as the case may be, deems appropriate.  Any of
                 such insurance may be carried by, through, or with any captive
                 or affiliated insurance company or by way of self-insurance as
                 the Borrower or any Subsidiary, as the case may be, deems
                 appropriate; and

                          (vi)  use the proceeds of Advances for general
                 corporate purposes (including the replacement of the Previous
                 Credit Agreements) and to repurchase or refinance, from time
                 to time, commercial paper issued by the Borrowers.
                                                                            
         Nothing in this subsection shall prohibit the Borrower or any of its
         Subsidiaries from discontinuing any business, forfeiting any license,
         right or franchise or discontinuing the operation or maintenance of
         any of its properties to the extent it deems appropriate in the
         conduct of its business.

                 (b)  Reporting Requirements.  Furnish to the Banks:

                          (i) as soon as available and in any event within 60

                 financial condition of the Borrower and its consolidated
                 Subsidiaries as at the end of such quarter and the related
                 statements of income and retained earnings of the Borrower and
                 its consolidated Subsidiaries for the period commencing at the
                 end of the previous fiscal year and ending with the

                                                                              30

                 end of such quarter, certified by a principal financial or
                 accounting officer of the Borrower; provided that the Borrower
                 may deliver, in lieu of the foregoing, the quarterly report of
                 the Borrower for such fiscal quarter on Form 10-Q filed with
                 the Securities and Exchange Commission or any governmental
                 authority succeeding to the functions of such Commission, but
                 only so long as the financial statements contained in such
                 quarterly report on Form 10-Q relate to the same companies and
                 are substantially the same in content as the financial
                 statements referred to in the preceding provisions of this
                 clause (i);

                          (ii) as soon as available and in any event within 90
                 days after the end of each fiscal year of the Borrower, a copy
                 of the annual report for such year for the Borrower and its
                 Subsidiaries, containing the audited consolidated financial
                 statements of the Borrower and its consolidated Subsidiaries
                 for such year and accompanied by an auditors' report of
                 Deloitte & Touche or other independent public accountants of
                 nationally recognized standing that such financial statements
                 were prepared in accordance with generally accepted accounting
                 standards and present fairly the consolidated financial
                 condition of the Borrower and its consolidated Subsidiaries
                 and results of operations of the Borrower and its consolidated
                 Subsidiaries;

                          (iii) promptly after the sending or filing thereof,
                 copies of all reports which the Borrower sends to its
                 stockholders generally, and copies of all reports and
                 registration statements (without exhibits) which the Borrower
                 files with the Securities and Exchange Commission or any
                 national securities exchange (other than registration
                 statements relating to employee benefit plans);

                          (iv) promptly after the filing or receiving thereof,
                 copies of any notices of any of the events set forth in
                 Section 4043(b) of ERISA or the regulations thereunder which
                 the Borrower or any Subsidiary files with the PBGC, or which
                 the Borrower or any Subsidiary receives from the PBGC to the
                 effect that proceedings or other action by the PBGC is to be
                 instituted;

                          (v) such other information respecting the condition
                 or operations, financial or otherwise, of the Borrower or any
                 of its Subsidiaries as any Bank through the Administrative
                 Agent may from time to time reasonably request; and

                          (vi) at any time the Borrower is not a
                 publicly-reporting company, upon the request of Administrative
                 Agent (and in a form acceptable to Administrative Agent), such
                 information respecting the condition or operations, financial
                 or otherwise, of the Borrower or any of its Subsidiaries as
                 the Borrower would have included in any reports filed with the
                 Securities and Exchange Commission if it had continued to be a
                 publicly-reporting company.

                 (c)  Notices.  Promptly give notice to the Administrative
Agent and each Bank:

                          (i) of the occurrence of any Event of Default or any
                 event which, with the giving of notice or the passage of time,
                 or both, would become an Event of Default; and

                          (ii) of the commencement of any litigation,
                 investigation, or proceeding affecting the Borrower or any of
                 its Subsidiaries before any court, governmental authority or
                 arbitrator which, in the reasonable judgment of the Borrower,
                 could have a material adverse effect on the business,
                 operations, property, or financial or other condition of the
                 Borrower and its Subsidiaries, taken as a whole.

         Each notice pursuant to this subsection shall be accompanied by a

                          (i) concurrently with the delivery of the financial
                 statements referred to in Section 5.01(b)(ii), a letter signed
                 by the independent public accountants, certifying such
                 financial statements to the effect that, in the course of the
                 examination upon which their report for such fiscal year was
                 based (but without any special or additional audit procedures
                 for that purpose other than review of the terms and provisions
                 of this Agreement), they did not become aware of any Event of
                 Default involving financial or accounting matters or any
                 condition or event which, after notice or lapse of time, or
                 both, would constitute such an Event of Default, or, if such
                 accountants became aware of any such Event of Default or other
                 condition or event, specifying the nature thereof; and

                          (ii) concurrently with the delivery of the financial

                 its covenants and other agreements, and satisfied every
                 condition, contained in this Agreement to be observed,
                 performed, or satisfied by it, and that such officer has
                 obtained no knowledge of any Event of Default or any event
                 which, with notice or lapse of time, or both, would become an
                 Event of Default, except as specified in such certificate.

                 SECTION 5.02.  Negative Covenants.  So long as any Advance
shall remain unpaid or any Bank shall have any Commitment hereunder, the
Borrower will not, without the written consent of the Majority Banks:

                 (a)  Liens, Etc.  (i) Create, assume, incur or suffer to
         exist, or permit any Subsidiary to create, assume, incur, or suffer to

         owned or hereafter acquired, of any Subsidiary, to secure any Debt of
         the Borrower or any other Person (other than the Advances made
         hereunder), without in any such case making effective provision
         whereby all of the Advances made hereunder shall be directly secured
         equally and ratably with such Debt, excluding, however, from the
         operation of the foregoing provisions of this paragraph (i) any Lien
         upon capital stock or indebtedness of any corporation existing at the
         time such corporation becomes a Subsidiary, or existing upon capital
         stock or indebtedness of a Subsidiary at the time of acquisition of
         such capital stock or indebtedness, and any extension, renewal, or
         replacement (or successive extensions, renewals, or replacements) in
         whole or in part of any such Lien; provided, however, that the
         principal amount of Debt secured thereby shall not exceed the
         principal amount of Debt so secured at the time of such extension,
         renewal, or replacement; and; provided further that such Lien shall be
         limited to all or such part of the capital stock or indebtedness which
         secured the Lien so extended, renewed, or replaced;

                 (ii) create, assume, incur, or suffer to exist, or permit any
         Restricted Subsidiary to create, assume, incur or suffer to exist, any
         Lien upon any Principal Property, whether owned or leased on the date
         hereof or hereafter acquired, to secure any Debt of the Borrower or
         any other Person (other than the Advances made hereunder), without in
         any such case making effective provision whereby all of the Advances
         made hereunder shall be directly secured equally and ratably with such
         Debt, excluding, however, from the operation of the foregoing
         provisions of this paragraph (ii):

                                  (A) any Lien upon property owned or leased by
                          any corporation existing at the time such corporation
                          becomes a Restricted Subsidiary, so long as such Lien
                          covers, either (x) the assets so encumbered
                          immediately prior to an acquisition of the Restricted
                          Subsidiary or (y) assets substituted for any assets
                          described in clause (x) preceding (the "acquired
                          assets"), so long as the approximate fair market
                          value of the substituted assets does not exceed the
                          approximate fair market value of the acquired assets
                          for which the substitution is being made;

                          or within 180 days after, the acquisition of such
                          property for the purpose of financing all or any part
                          of the purchase price thereof, so long as such Lien

                                  (D) any Lien securing Debt of a Restricted
                          Subsidiary owing to the Borrower or to another
                          Restricted Subsidiary;

                                  (E) any Lien existing on the date of
                          execution of this Agreement and set forth on Schedule
                          III hereto;

                                  (F) Liens created in favor of Banks to secure
                          the Obligation;

                                  (G) any Liens securing Debt of the Borrower
                          under the Other Credit Agreements, so long as the
                          Banks are granted Liens of equal priority upon any
                          property to which such Liens under the Other Credit
                          Agreements attach; and

                                  (H) any extension, renewal, or replacement
                          (or successive extensions, renewals, or replacements)
                          in whole or in part of any Lien referred to in the
                          foregoing clauses (A) to (G), inclusive; provided,
                          however, that the principal amount of Debt secured
                          thereby shall not exceed the principal amount of Debt
                          so secured at the time of such extension, renewal, or
                          replacement; and; provided further that such Lien
                          shall be limited to all or such part of the property
                          which secured the Lien so extended, renewed, or
                          replaced (plus improvements on such property).

                 Notwithstanding the foregoing provisions of this paragraph
                 (ii), the Borrower may, and may permit any Restricted
                 Subsidiary to, create, assume, incur, or suffer to exist any
                 Lien upon any Principal Property which is not excepted by
                 clauses (A) through (F), above, without equally and ratably
                 securing the Advances; provided that the aggregate amount of
                 Debt then outstanding secured by such Lien and all similar
                 Liens does not exceed the greater of (i) $150,000,000, and
                 (ii) 10% of the total consolidated stockholders' equity of the
                 Borrower as shown on the most recently audited consolidated
                 balance sheet required to be delivered to the Banks pursuant
                 to Section 5.01(b)(ii).  For the purpose of this paragraph
                 (ii), the following types of transactions shall not be deemed
                 to create a Lien to secure any Debt:

                                  (A) the sale or other transfer of (y) any
                          oil, gas, or minerals in place for a period of time
                          until, or in an amount such that, the purchaser will
                          realize therefrom a specified amount of money
                          (however determined) or a specified amount of such
                          oil, gas, or minerals, or (z) any other interest in
                          property of the character commonly referred to as a
                          "production payment"; and

                                  (B) any Lien in favor of the United States of
                          America or any state thereof, or any other country,
                          or any political subdivision of any of the foregoing,
                          to secure partial, progress, advance or other
                          payments pursuant to the provisions of any contract
                          or statute,

                          or any Lien upon property of the Borrower or a
                          Restricted Subsidiary intended to be used primarily
                          for the purpose of, or in connection with, air or
                          water pollution control; provided that no such Lien
                          shall extend to any other property of the Borrower or
                          a Restricted Subsidiary.

                 (b)  Debt.  (i) Permit Union Pacific Resources Inc., a
         Canadian corporation and wholly owned Subsidiary of the Borrower, or
         any of its Subsidiaries (collectively, the "Designated Subsidiaries")
         to incur any Debt which would result in the aggregate principal amount
         of Debt (other than Debt to the Borrower or any other Subsidiary) of
         all the Designated Subsidiaries, on a consolidated basis, exceeding
         US$1,400,000,000; and

                 (ii)   permit any of its Subsidiaries (other than the
         Designated Subsidiaries) to incur any Debt which would result in the
         aggregate principal amount of Debt (other than (A) Debt to the
         Borrower or any other Subsidiary and (B) Debt represented by the UPRCC
         Notes) of all Subsidiaries (other than the Designated Subsidiaries),
         on a consolidated basis, exceeding US$150,000,000; provided that in
         the event that the UPRCC Notes are issued, the Borrower shall apply
         75% of the Net Proceeds received by UPRCC from the issuance of the
         UPRCC Notes to (x) permanently and ratably reduce the Commitments
         and/or (y) repay Debt of the Designated Subsidiaries and reduce the
         amount of the maximum permitted Debt of the Designated Subsidiaries as
         set forth in clause (i) of this Section by an amount equal to such
         repayment.

                 (c)  Restriction on Fundamental Changes of the Borrower.
         Enter into any transaction of merger or consolidation, or convey,
         transfer, or lease its properties and assets substantially as an
         entirety to any Person, unless:

                          (i) either (A) Borrower (in any merger or
                 consolidation involving Borrower) is the surviving entity, or
                 (B) the corporation formed by such consolidation or into which
                 the Borrower is merged or the Person which acquires by
                 conveyance or transfer, or which leases, the properties and
                 assets of the Borrower substantially as an entirety (the
                 "Successor Corporation") shall either (x) immediately after
                 giving effect to such merger, consolidation, conveyance,
                 transfer or lease, have then-effective ratings (or implied
                 ratings) published by Moody's and S&P applicable to such
                 Successor Corporation's senior, unsecured,
                 non-credit-enhanced, long term indebtedness for borrowed
                 money, which ratings shall be Baa3 or higher (if assigned by
                 Moody's) or BBB- or higher (if assigned by S&P), or (y) be
                 acceptable to Majority Banks in their reasonable
                 determination;

                          (ii) any Successor Corporation shall be a corporation
                 organized and existing under the laws of the United States of
                 America, any state thereof or the District of Columbia, and
                 shall expressly assume, by amendment to this Agreement
                 executed by the Borrower and such Successor Corporation and
                 delivered to the Administrative Agent, the due and punctual
                 payment of the principal of, and interest on, the Advances
                 made hereunder and any other amounts payable under this
                 Agreement and the performance or observance of every covenant
                 hereof on the part of the Borrower or such Principal
                 Subsidiary to be performed or observed;

                          (iii) immediately after giving effect to such
                 transaction, no Event of Default and no event which, with
                 notice or lapse of time, or both, would become an Event of
                 Default, shall have occurred and be continuing;

                          (iv) if, as a result of any such consolidation or
                 merger or such conveyance, transfer or lease, properties or
                 assets of the Borrower or any Principal Subsidiary would
                 become subject to a Lien which would not be permitted by
                 Section 5.02(a), the Borrower, the Principal Subsidiary or the
                 Successor Corporation, as the case may be, shall take such
                 steps as shall be necessary

                 effectively to secure the Advances made hereunder equally and
                 ratably with (or prior to) all Debt secured thereby; and

                          (v) the Borrower shall have delivered to the
                 Administrative Agent a certificate signed by an executive
                 officer of the Borrower and a written opinion of counsel
                 satisfactory to the Administrative Agent (who may be counsel
                 to the Borrower), each stating that such transaction and such
                 amendment to this Agreement comply with this Section 5.02(c)
                 and that all conditions precedent herein provided for relating
                 to such transaction have been satisfied.

                 (d)  Prohibition on Sale of UPRC Stock and Fundamental Changes
         of UPRC.  (i) Convey, sell, assign, or otherwise transfer (or permit
         any Subsidiary to so convey, sell, assign or transfer) all or any of
         the shares of capital stock of Union Pacific Resources Company
         ("UPRC") or any Successor Subsidiary (as hereinafter defined) now
         owned or hereafter acquired by the Borrower or any Subsidiary and (ii)
         permit UPRC or any Successor Subsidiary (as hereinafter defined) to
         enter into any transaction of merger or consolidation with, or to
         convey, transfer or lease its properties substantially as an entirety
         to, any Person, other than mergers or consolidations with, or
         conveyances, transfers or leases to, Borrower or any other Subsidiary.
         For purposes of this subsection, "Successor Subsidiary" shall mean any
         Subsidiary which is formed by any merger or consolidation of UPRC or
         which acquires by conveyance, transfer or lease substantially all the
         properties of UPRC or any Successor Subsidiary.

                 (e)  Ratio of Maximum Total Debt to Consolidated EBITDAX.
         Permit the ratio (calculated at the end of each fiscal quarter of the
         Borrower) that (i) the aggregate amount of the consolidated Debt of
         Borrower and its consolidated Subsidiaries bears to (ii) consolidated
         EBITDAX of the Borrower and its consolidated Subsidiaries (for the
         period of four consecutive fiscal quarters then ended) to be more than
         3.25:1.00.  For purposes of determining compliance with this covenant
         with respect to four-quarter periods ended on or prior to December 31,
         1998, data of Norcen shall be included in the calculation of
         consolidated EDITDAX of the Company and its consolidated Subsidiaries.

                 (f)  Compliance with ERISA.  To the extent that any event or
         action set forth in clauses (i) through (iv) below would subject the
         Borrower and its Subsidiaries, taken as a whole, to any material
         liability to the PBGC or otherwise,

                          (i) terminate, or permit any Subsidiary to terminate,
                 any Plan;

                          (ii) engage in, or permit any Subsidiary to engage
                 in, any "prohibited transaction" (as defined in Section 4975
                 of the Code) involving any Plan;

                          (iii) incur or suffer to exist, or permit any
                 Subsidiary to incur or suffer to exist, any "accumulated
                 funding deficiency" (as defined in Section 302 of ERISA),
                 whether or not waived, involving any Plan; or

                          (iv) allow or suffer to exist, or permit any
                 Subsidiary to allow or suffer to exist, any event or condition
                 which presents a risk of incurring a liability to the PBGC by
                 reason of termination of any Plan.

                 (g)  Affiliate Transactions.  Enter into (or permit any
         Restricted Subsidiary to enter into) any material transaction with any
         of its Affiliates, other than any transaction described in public
         documents filed with the Securities and Exchange Commission or
         otherwise disclosed publicly prior to the Closing Date, or any
         transaction in the ordinary course of business and upon fair and
         reasonable terms not materially less favorable than Borrower or such
         Restricted Subsidiary could obtain or could be entitled to in an
         arm's-length transaction with a Person that was not its Affiliate.

                 (h)  Principal Subsidiaries.  Permit the combined EBITDAX of
         the Borrower and the Principal Subsidiaries to be less than 80% of the

                               Events of Default

                 If any of the following events ("Events of Default") shall 
occur and be continuing:

                 (a) the Borrower shall fail to pay any principal of any
         Advance when the same becomes due and payable; provided that if any
         such failure shall result from the malfunctioning or shutdown of any
         wire transfer or other payment system employed by the Borrower to make
         such payment or from an inadvertent error of a technical or clerical
         nature by the Borrower or any bank or other entity employed by the
         Borrower to make such payment, no Event of Default shall result under
         this paragraph (a) during the period (not in excess of two Business
         Days) required by the Borrower to make alternate payment arrangements;
         or

                 (b)  the Borrower shall fail to pay any interest on any
         Advance or any fee payable hereunder or under any agreement executed
         in connection herewith when the same becomes due and payable and such
         failure shall remain unremedied for ten days; or

                 (c) any representation or warranty made by the Borrower herein
         or by the Borrower (or any of its officers) in connection with this
         Agreement (including, without limitation, any representation or
         warranty deemed made by the Borrower at the time of any Advance
         pursuant to Article III) shall prove to have been incorrect in any
         material respect when made or deemed made; or

                 (d) the Borrower shall fail to perform or observe any other
         term, covenant, or agreement contained in this Agreement on its part
         to be performed or observed if such failure shall remain unremedied
         for 30 days after written notice thereof shall have been given to the
         Borrower by the Administrative Agent or any Bank; or

                 (e) (i) the Borrower or any Principal Subsidiary shall fail to
         pay any amount of principal or interest when due (or within any
         applicable grace period) with respect to any Debt of the Borrower or
         any Principal Subsidiary, whether such Debt now exists or shall
         hereafter be created, in an aggregate outstanding principal amount
         exceeding $50,000,000 ("Material Debt") or (ii) an event of default as
         defined in any mortgage, indenture, or instrument under which there
         may be issued, or by which there may be secured or evidenced, any Debt
         of the Borrower or any Principal Subsidiary, whether such Debt now
         exists or shall hereafter be created, shall happen and shall result in
         Material Debt becoming or being declared due and payable prior to the
         date on which it would otherwise become due and payable, and such
         declaration shall not be rescinded or annulled; or

                 (f) (i) the Borrower or any Principal Subsidiary shall
         commence any case, proceeding, or other action, or make any filing (A)
         under any existing or future law of any jurisdiction, domestic or
         foreign, relating to bankruptcy, insolvency, reorganization, or relief
         of debtors, seeking to have an order for relief entered with respect
         to it, or seeking to adjudicate it a bankrupt or insolvent, or seeking
         reorganization, arrangement, adjustment, winding-up, liquidation,
         dissolution, composition, or other relief with respect to it or its
         debts, or (B) seeking appointment of a receiver, trustee, custodian,
         or other similar official for it or

         for all or any substantial part of its assets, or the Borrower or any
         Principal Subsidiary shall make a general assignment for the benefit
         of its creditors; or

                 (ii) there shall be commenced against the Borrower or any
         Principal Subsidiary any case, proceeding or other action of a nature
         referred to in clause (i) above which (A) results in the entry of an
         order for relief or any such adjudication or appointment or (B)
         remains undismissed, undischarged, or unbonded for a period of 60
         days; or

                          (iii) there shall be commenced against the Borrower
                 or any Principal Subsidiary any case, proceeding, or other
                 action seeking issuance of a warrant of attachment, execution,
                 distraint, or similar process against all or any substantial
                 part of its assets which results in the entry of an order for
                 any such relief which shall not have been vacated, discharged,
                 or stayed or bonded pending appeal within 60 days from the
                 entry thereof; or

                          (iv) the Borrower or any Principal Subsidiary shall
                 take any action in furtherance of or indicating its consent
                 to, approval of, or acquiescence in, any of the acts set forth
                 in clause (i), (ii), or (iii) above; or

                          (v) the Borrower or any Principal Subsidiary shall
                 generally not, or shall be unable to, or shall admit in
                 writing its inability to, pay its debts as they become due;

                 (g) a Material Plan shall fail to maintain the minimum funding
         standards required by Section 412 of the Code for any plan year or a
         waiver of such standard is sought or granted under Section 412(d), or
         a Material Plan is, shall have been, or will be terminated or the
         subject of termination proceedings under ERISA, or the Borrower or any
         of its Subsidiaries or any ERISA Affiliate has incurred or will incur
         a liability to or on account of a Material Plan under Sections 4062,
         4063, or 4064 of ERISA, and there shall result from any such event
         either a liability or a material risk of incurring a liability to the
         PBGC or a Material Plan (or a related trust) which will have a
         material adverse effect upon the business, operations or the condition
         (financial or otherwise) of the Borrower and its Subsidiaries, taken
         as a whole;

                 (h) the Borrower or any ERISA Affiliate shall have been
         notified by the sponsor of a Multiemployer Plan that it has incurred
         withdrawal liability to such Multiemployer Plan in an amount which,
         when aggregated with all other amounts required to be paid to
         Multiemployer Plans in connection with withdrawal liabilities
         (determined as of the date of such notification), will have a material
         adverse effect upon the business, operations, or the condition
         (financial or otherwise) of the Borrower and its Subsidiaries, taken
         as a whole; or

                 (i) any "Event of Default" described in either of the Existing
         Credit Agreements shall occur; then, and in any such event, the
         Administrative Agent

                 (i) shall at the request, or may with the consent, of the
         Majority Banks, by notice to the Borrower, declare the obligation of
         each Bank to make Advances to be terminated, whereupon the same shall
         forthwith terminate;

                 (ii) shall at the request, or may with the consent, of Banks
         owed at least 51% of the then aggregate unpaid principal amount of the
         Advances owing to Banks, by notice to the Borrower, declare the
         Advances, all interest thereon and all other amounts payable under
         this Agreement to be forthwith due and payable, whereupon the
         Advances, all such interest and all such amounts shall become and be
         forthwith due and payable, without presentment, demand, protest,
         notice of intention to accelerate, notice of acceleration, or further
         notice of any kind, all of which are hereby expressly waived by the
         Borrower; and

                 (iii) shall at the request, or may with the consent, of  the
         Majority Banks, exercise any and all other legal and equitable rights
         afforded by the Loan Papers, applicable law, or in equity, including,
         but not limited to, the right to bring suit or other proceedings for
         specific performance or otherwise in aid of any right granted to
         Administrative Agent or any Bank hereunder; provided, however, that in
         the event of an actual or deemed entry of an order for relief with
         respect to the Borrower or any of its Subsidiaries under the Federal
         Bankruptcy Code, (A) the obligation of each Bank to make Advances
         shall automatically be terminated and (B) the Advances, all such
         interest and all such amounts shall automatically become and be due
         and payable, without presentment, demand, protest, or any notice of
         any kind, all of which are hereby expressly waived by the Borrower.


                                  ARTICLE VII

                            The Administrative Agent

                 SECTION 7.01.  Authorization and Action.  Each Bank hereby
appoints and authorizes the Administrative Agent to take such action as
administrative agent on its behalf and to exercise such powers under this
Agreement as are delegated to the Administrative Agent by the terms hereof,
together with such powers as are reasonably incidental thereto.  As to any
matters not expressly provided for by this Agreement (including, without
limitation, enforcement or collection of the amounts due hereunder), the
Administrative Agent shall not be required to exercise any discretion or take
any action, but shall be required to act or to refrain from acting (and shall
be fully protected in so acting or refraining from acting) upon the
instructions of the Majority Banks, and such instructions shall be binding upon
all Banks and all holders of Advances; provided, however, that the
Administrative Agent shall not be required to take any action which exposes the
Administrative Agent to personal liability or which is contrary to this
Agreement or applicable law.  The Administrative Agent agrees to give to each
Bank prompt notice of each notice given to it by the Borrower pursuant to the
terms of this Agreement.

                 SECTION 7.02.  Administrative Agent's Reliance, Etc.  Neither
the Administrative Agent nor any of its directors, officers, agents, or
employees shall be liable for any action taken or omitted to be taken by it or
them under or in connection with this Agreement, except for its or their own
gross negligence or wilful misconduct. Without limitation of the generality of
the foregoing, the Administrative Agent:

                 (i) may consult with legal counsel (including counsel for the
         Borrower), independent public accountants, and other experts selected
         by it and shall not be liable for any action taken or omitted to be
         taken in good faith by it in accordance with the advice of such
         counsel, accountants or experts;

                 (ii) makes no warranty or representation to any Bank and shall
         not be responsible to any Bank for any statements, warranties, or
         representations made in or in connection with this Agreement;

                 (iii) shall not have any duty to ascertain or to inquire as to
         the performance or observance of any of the terms, covenants or
         conditions of this Agreement on the part of the Borrower or to inspect
         the property (including the books and records) of the Borrower;

                 (iv) shall not be responsible to any Bank for the due
         execution, legality, validity, enforceability, genuineness,
         sufficiency or value of this Agreement or any other instrument or
         document furnished pursuant hereto; and

                 (v) shall incur no liability under or in respect of this
         Agreement by acting upon any notice, consent, certificate or other
         instrument or writing (which may be by telecopy, telegram or cable)
         believed by it to be genuine and signed or sent by the proper party or
         parties.

                 SECTION 7.03.  Administrative Agent and Affiliates.  With
respect to its Commitment, Chase Bank of Texas, N.A. shall have the same rights
and powers under this Agreement as any other Bank, and may exercise the same as
though it were not the Administrative Agent and the term "Bank" or "Banks"
shall, unless otherwise expressly indicated, include Chase Bank of Texas, N.A.
in its individual capacity.  Chase Bank of Texas, N.A. and its affiliates may
accept deposits from, lend money to, act as trustee under indentures of, and
generally engage in any kind of business with, the Borrower, any of its
Subsidiaries and any Person who may do business with or own securities of the
Borrower or any such Subsidiary, all as if Chase Bank of Texas, N.A. were not
the Administrative Agent and without any duty to account therefor to the Banks.

                 SECTION 7.04.  Bank Credit Decision.  Each Bank acknowledges
that it has, independently and without reliance upon the Administrative Agent
or any other Bank and based on the financial statements referred to in Article
IV and such other documents and information as it has deemed appropriate, made
its own credit analysis and decision to enter into this Agreement.  Each Bank
also acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Bank and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement.

                 SECTION 7.05.  Indemnification.  The Banks agree to indemnify
the Administrative Agent, acting in its agency capacity, (to the extent not
reimbursed by the Borrower), ratably as computed as set forth below from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever which may be imposed on, incurred by or asserted against the
Administrative Agent in any way relating to, or arising out of, this Agreement
or any action taken or omitted by the Administrative Agent under this
Agreement; provided that no Bank shall be liable to the Administrative Agent
for any portion of such liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements resulting from the
Administrative Agent's gross negligence or wilful misconduct.  Without
limitation of the foregoing, each Bank agrees to reimburse the Administrative
Agent promptly upon demand for its ratable share of any out-of-pocket expenses
(including counsel fees) incurred by the Administrative Agent in connection
with the preparation, execution, delivery, administration, modification,
amendment or enforcement (whether through negotiations, legal proceedings, or
otherwise) of, or legal advice in respect of rights or responsibilities under,
this Agreement, to the extent that the Administrative Agent is not reimbursed
for such expenses by the Borrower.  For purposes of this Section 7.05, ratable
allocations among the Banks shall be made (i) in respect of any demand by the
Administrative Agent prior to termination of the Commitments, according to the
respective amounts of their Commitments and outstanding Term Advances and (iii)
thereafter according to the respective principal amounts of the Advances then
outstanding to them.

                 SECTION 7.06.  Successor Administrative Agent.  The
Administrative Agent may resign at any time by giving written notice thereof to
the Banks and the Borrower and may be removed at any time with or without cause
by the Majority Banks.  Upon any such resignation or removal, the Majority
Banks shall have the right to appoint a successor Administrative Agent with the
consent of the Borrower (which consent shall not be required if at the time of
such appointment any Event of Default or an event which with the passage of
time or the giving of notice or both would become an Event of Default has
occurred and is continuing).  If no successor Administrative Agent shall have
been so appointed by the Majority Banks, and shall have accepted such
appointment, within 30 days after the retiring Administrative Agent's giving of
notice of resignation or the Majority Banks' removal of the retiring
Administrative Agent, then the retiring Administrative Agent may, on behalf of
the Banks, appoint a successor Administrative Agent, which shall be a
commercial bank organized or licensed under the laws of the United States of
America or of any state thereof and having a combined capital and surplus of at
least $500,000,000.  Upon the acceptance of any appointment as Administrative
Agent hereunder by a successor Administrative Agent, such successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Administrative Agent, and
the retiring Administrative Agent shall be discharged from its duties and
obligations under this Agreement.  After any retiring Administrative Agent's





<PAGE>   43
                                                                              39

resignation or removal hereunder as Administrative Agent, the provisions of
this Article VII shall inure to its benefit as to any actions taken or omitted
to be taken by it while it was Administrative Agent under this Agreement.


                                  ARTICLE VIII

                                 Miscellaneous

                 SECTION 8.01.  Amendments, Etc.  No amendment or waiver of any
provision of this Agreement nor consent to any departure by the Borrower
therefrom, shall in any event be effective, unless the same shall be in writing
and signed by the Majority Banks, and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given; provided, however, that no amendment, waiver, or consent shall, unless
in writing and signed by all the Banks, do any of the following:  (a) waive any
of the conditions specified in Section 3.01 or 3.02 (if and to the extent that
the Borrowing which is the subject of such waiver would involve an increase in
the aggregate outstanding amount of Advances over the aggregate amount of
Advances outstanding immediately prior to such Borrowing), (b) increase, or
(except as provided in Section 2.10) extend the scheduled termination of, the
Commitments of the Banks or subject the Banks to any additional obligations,
(c) reduce the principal of, or interest on, the Advances or any fees or other
amounts payable hereunder, (d) postpone any date fixed for any payment of
principal of, or interest on, the Advances or any fees or other amounts payable
hereunder, (e) make any change which would alter the percentage of the
Commitment, or of the aggregate unpaid principal amount of the Advances, or the
number of Banks, which shall otherwise be required for the Banks or any of them
to take any action hereunder, or (f) amend this Section 8.01, and; provided
further that no amendment, waiver or consent shall, unless in writing and
signed by the Administrative Agent in addition to the Banks required above to
take such action, affect the rights or duties of the Administrative Agent under
this Agreement.

                 SECTION 8.02.  Notices, Etc.  All notices and other
communications provided for hereunder shall be in writing (including telecopy,
telegraphic or cable communication) and telecopied, mailed, telegraphed, cabled
or delivered, if to the Borrower, at its address at P.O. Box 7, 801 Cherry

to the telegraph company, or delivered to the cable company, respectively,
except that notices and communications to the Administrative Agent pursuant to
Article II or VII shall not be effective until received by the Administrative
Agent.  The Administrative Agent shall be entitled to rely on any oral notice
made pursuant to Section 2.03(a)(v) believed by it to be genuine and made by
the proper party or parties, and the Borrower and the Banks, as the case may
be, agree to be conclusively bound by the Administrative Agent's records in
respect of any such notice.

                 SECTION 8.03.  No Waiver; Remedies.  No failure on the part of
any Bank or the Administrative Agent to exercise, and no delay in exercising,
any right hereunder shall operate as a waiver thereof; nor shall any single or
partial exercise of any such right preclude any other or further exercise
thereof or the exercise of any other right.  The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

                                                                              40

                 SECTION 8.04.  Costs, Expenses and Taxes.  (a)  The Borrower

In addition, the Borrower agrees to pay any present or future stamp or
documentary taxes or any other excise or property taxes, charges, or similar
levies which arise from the execution and delivery of this Agreement and agrees
to save the Administrative Agent and each Bank harmless from and against any
and all liabilities with respect to or resulting from any delay in paying or
omission to pay such taxes.

                 (b)  If any payment of principal of any Eurodollar Rate
Contract Advance or Competitive Advance is made by the Borrower to or for the
account of a Bank other than on the last day of the Interest Period for such
Contract Advance, or on the maturity date of such Competitive Advance, as the
case may be, or as a result of a payment pursuant to Section 2.07, or as a
result of acceleration of the maturity of the Advances pursuant to Article VI,
or for any other reason, or by an Eligible Assignee to a Bank other than on the
last day of the Interest Period (or the final maturity date in the case of a
Competitive Advance) for such Advance upon an assignment of rights and
obligations under this Agreement pursuant to Section 8.07 as a result of a
demand by the Borrower pursuant to Section 8.07(a), or an assignment of rights
and obligations under this Agreement pursuant to Section 2.17 as a result of a
demand by the Borrower, or if the Borrower fails to convert or continue any
Contract Advance hereunder after irrevocable notice of such conversion or
continuation has been given pursuant to Section 2.04, the Borrower shall, upon
demand by such Bank (with a copy of such demand to the Administrative Agent),
pay to the Administrative Agent for the account of such Bank any amounts
required to compensate such Bank for any additional losses, costs or expenses
which it may reasonably incur as a result of such payment or failure,
including, without limitation, any loss (excluding loss of anticipated
profits), cost or expense incurred by reason of the liquidation or reemployment
of deposits or other funds acquired by such Bank to fund or maintain such
Advance.  A certificate of such Bank setting forth the amount demanded
hereunder and the basis therefor shall, in the absence of manifest error, be
conclusive and binding for all purposes.

                 SECTION 8.05.  Right of Set-off.  Upon (i) the occurrence and
during the continuance of any Event of Default and (ii) the making of the
request or the granting of the consent specified by Article VI to authorize the
Administrative Agent to declare the Advances due and payable pursuant to the
provisions of Article VI, each Bank is hereby authorized at any time and from
time to time, to the fullest extent permitted by law, to set-off and apply any
and all deposits (general or special, time or demand, provisional or final) at
any time held and other indebtedness at any time owing by such Bank to or for
the credit or the account of the Borrower against any and all of the Obligation
of the Borrower now or hereafter existing under this Agreement and the Advances
made by such Bank, irrespective of whether or not such Bank shall have made any
demand under this Agreement and although such obligations may be unmatured.
Each Bank agrees promptly to notify the Borrower and the Administrative Agent
after any such set-off and application made by such Bank; provided that the
failure to give such notice shall not affect the validity of such set-off and
application.  The rights of each Bank under this Section 8.05 are in addition
to other rights and remedies (including, without limitation, other rights of
set-off) which such Bank may have.

                 SECTION 8.06.  Binding Effect.  This Agreement shall become
effective when it shall have been executed by the Borrower and the
Administrative Agent and when the Administrative Agent shall have been notified
by each Bank that such Bank has executed it and thereafter shall be binding
upon and inure to the benefit of the Borrower, the Administrative Agent and
each Bank and their respective successors and assigns.

                 SECTION 8.07.  Assignments and Participations.  (a)  Each Bank
may and, if demanded by the Borrower pursuant to subsection (g) hereof, shall
assign to one or more banks or other entities all or a portion of its rights
and obligations under this Agreement (including, without limitation, all or a
portion of its Commitment and the Advances owing to it); provided, however,
that (i) each such assignment shall be of a constant, and not a varying,
percentage of all of the rights and obligations of the assigning Bank under
this Agreement (except that Term Advances and Commitments may be assigned
separately), (ii) in the case of a partial assignment, the amount of the
Commitment or Term Advances of the assigning Bank being assigned pursuant to
each such assignment (determined as of the date of the Assignment and
Acceptance with respect to such assignment) shall in no event be less than
$10,000,000 and shall be an integral multiple of $5,000,000, (iii) each such
assignment shall be to an Eligible Assignee, and (iv) the parties to each such
assignment shall execute and deliver to the Administrative Agent, for its
acceptance and recording in the Register (as defined in Section 8.07(c)), an
Assignment and Acceptance, together with a processing fee of $3,500.  Upon such
execution, delivery, acceptance, and recording, from and after the effective
date specified in each Assignment and Acceptance, which effective date shall be
at least three Business Days after the execution thereof, (x) the assignee
thereunder shall be a party hereto and, to the extent that rights and
obligations hereunder have been assigned to it pursuant to such Assignment and
Acceptance, have the rights and obligations of a Bank hereunder, and (y) the
Bank assignor thereunder shall, to the extent that rights and obligations
hereunder have been assigned by it pursuant to such Assignment and Acceptance,
relinquish its rights and be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all or the remaining
portion of an assigning Bank's rights and obligations under this Agreement,
such Bank shall cease to be a party hereto).  Notwithstanding the foregoing
(unless such assignment is being made on demand of the Borrower pursuant to
subsection (g)), any Bank assigning its rights and obligations under this
Agreement may retain any Competitive Advances made by it outstanding at such
time, and in such case shall retain its rights hereunder in respect of any
Advances so retained until such Advances have been repaid in full in accordance
with this Agreement.

                 (b)  By executing and delivering an Assignment and Acceptance,
the Bank assignor thereunder and the assignee thereunder confirm to and agree
with each other and the other parties hereto as follows:

                 (i) other than as provided in such Assignment and Acceptance,
         such assigning Bank makes no representation or warranty and assumes no
         responsibility with respect to any statements, warranties or
         representations made in or in connection with this Agreement or the
         execution, legality, validity, enforceability, genuineness,
         sufficiency or value of this Agreement or any other instrument or
         document furnished pursuant hereto;

                 (ii) such assigning Bank makes no representation or warranty
         and assumes no responsibility with respect to the financial condition
         of the Borrower or the performance or observance by the Borrower of
         any of its obligations under this Agreement or any other instrument or
         document furnished pursuant hereto;

                 (iii) such assignee confirms that it has received a copy of
         this Agreement, together with copies of the financial statements
         referred to in subsection (e) of Article IV and such other documents
         and information as it has deemed appropriate to make its own credit
         analysis and decision to enter into such Assignment and Acceptance;

                 (iv) such assignee will, independently and without reliance
         upon the Administrative Agent, such assigning Bank or any other Bank
         and based on such documents and information as it shall deem
         appropriate at the time, continue to make its own credit decisions in
         taking or not taking action under this Agreement;

                 (v) such assignee confirms that it is an Eligible Assignee,
         except for any required consent of the Borrower and Administrative
         Agent;





<PAGE>   46
                                                                              42

                 (vi) such assignee appoints and authorizes the Administrative
         Agent to take such action as Administrative Agent on its behalf and to
         exercise such powers under this Agreement as are delegated to the
         Administrative Agent by the terms hereof, together with such powers as
         are reasonably incidental thereto; and

                 (vii) such assignee agrees that it will perform in accordance
         with their terms all the obligations which by the terms of this
         Agreement are required to be performed by it as a Bank.

                 (c)  The Administrative Agent shall maintain at its address
referred to in Section 8.02 a copy of each Assignment and Acceptance delivered
to and accepted by it and a register for the recordation of the names and
addresses of the Banks and the Commitment of, and principal amount of the
Advances owing to, each Bank from time to time (the "Register").  The entries
in the Register shall be conclusive and binding for all purposes, absent
manifest error, and the Borrower, the Administrative Agent and the Banks may
treat each Person whose name is recorded in the Register as a Bank hereunder
for all purposes of this Agreement.  The Register shall be available for
inspection by the Borrower or any Bank at any reasonable time and from time to
time upon reasonable prior notice.

                 (d)  Upon its receipt of an Assignment and Acceptance executed
by an assigning Bank and an assignee that it is an Eligible Assignee, the
Administrative Agent shall, if such Assignment and Acceptance has been
completed and is in substantially the form of Exhibit B hereto, and if the
processing fees required by Section 8.07 have been paid to Administrative
Agent, (i) accept such Assignment and Acceptance, (ii) record the information
contained therein in the Register, (iii) give prompt notice thereof to the
Borrower and (iv) send a copy thereof to the Borrower.

                 (e)  Each Bank may sell participations to one or more banks or
other entities in or to all or a portion of its rights and obligations under
this Agreement (including, without limitation, all or a portion of its
Commitment and the Advances owing to it); provided, however, that (i) such
Bank's obligations under this Agreement (including, without limitation, its
Commitment to the Borrower hereunder) shall remain unchanged, (ii) such Bank
shall remain solely responsible to the other parties hereto for the performance
of such obligations and (iii) the Borrower, the Administrative Agent and the
other Banks shall continue to deal solely and directly with such Bank in
connection with such Bank's rights and obligations under this Agreement and;
provided further, however, that such Bank shall not agree with any such bank or
other financial institution to permit such bank or other financial institution
to enforce the obligations of the Borrower relating to the Advances or to
approve of any amendment, modification or waiver of any provision of this
Agreement (other than amendments, modifications, or waivers with respect to any
decrease in any fees payable hereunder or the amount of principal or rate of
interest which is payable in respect of such Advances or any extension of the
dates fixed for the payment thereof).

                 (f)  Any Bank may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
8.07, disclose to the assignee or participant or proposed assignee or
participant, any information relating to the Borrower furnished to such Bank by
or on behalf of the Borrower; provided that prior to any such disclosure, the
assignee or participant or proposed assignee or participant, if not an Eligible
Assignee, shall agree to preserve the confidentiality of any confidential
information relating to the Borrower received by it from such Bank.

                 (g)  If any Bank shall make demand for payment under or shall
notify the Borrower that it is affected by an event described in Section 2.11
or 2.15 hereunder or shall notify the Administrative Agent pursuant to Section
2.13 hereunder, then within 15 days after such demand or such notice, the
Borrower may (i) demand that such Bank assign in accordance with this Section
8.07 to one or more Eligible Assignees, designated by the Borrower all (but not
less than all) of such Bank's Commitment and the Advances owing to it within
the next succeeding 30 days; provided that if any such Eligible Assignee
designated by the Borrower shall fail to consummate such assignment on terms
acceptable to such Bank, or if the Borrower shall fail to designate any such
Eligible Assignees for all or part of such Bank's Commitment or Advances, then
such Bank may assign such





<PAGE>   47
                                                                              43

Commitment or Advances to any other Eligible Assignee in accordance with this
Section 8.07 during such 30-day period or (ii) so long as no Event of Default
has occurred and is continuing, terminate all (but not less than all) of such
Bank's Commitment and repay all (but not less than all) of such Bank's Advances
not so assigned on or before such 30th day in accordance with Sections 2.06 and
2.07(c) hereof (but without the requirements stated therein for ratable
treatment of the Banks).  Nothing in this Section 8.07(g) shall relieve the
Borrower of its obligations for payment under Section 2.11 or 2.15 arising
prior to an assignment or termination pursuant hereto.

                 (h)  Any Bank may at any time assign all or any portion of its
rights under this Agreement to a Federal Reserve Bank; provided that no such
assignment shall release a Bank from any of its obligations hereunder.  In
connection with any such assignment or proposed assignment, the Borrower will,
promptly upon the request of any Bank, execute and deliver to such Bank a note
evidencing the Borrower's obligations hereunder, in a form mutually
satisfactory to the Borrower and such Bank.

                 (i)  This Section 8.07 sets forth the exclusive manner by
which a Bank may assign its rights and obligations hereunder or sell
participations in or to its rights and obligations hereunder.

                 (j)  Each Bank agrees to notify the Borrower of any assignment
of or grant of a participating interest in any Advance and of the identity of
the assignee or participant.

                 (k)  The Borrower may not assign or delegate any rights or
obligations hereunder without the prior written consent of each Bank.

                 (l)  Notwithstanding anything to the contrary contained
herein, any Bank (a "Granting Bank") may grant to a special purpose funding
vehicle (an "SPC") sponsored by such Granting Bank, identified as such in
writing from time to time by the Granting Bank to the Administrative Agent and
the Borrower, the option to provide to the Borrower all or any part of any
Advance that such Granting Bank would otherwise be obligated to make to the
Borrower pursuant to this Agreement; provided that (i) nothing herein shall
constitute a commitment by any SPC to make any Advance, (ii) if an SPC elects
not to exercise such option or otherwise fails to provide all or any part of
such Advance, the Granting Bank shall be obligated to make such Advance
pursuant to the terms hereof.  The making of an Advance by an SPC hereunder
shall utilize the Commitment of the Granting Bank to the same extent, and as
if, such Advance were made by such Granting Bank.  Each party hereto hereby
agrees that no SPC shall be liable for any indemnity or similar payment
obligation under this Agreement (all liability for which shall remain with the
Granting Bank).  In furtherance of the foregoing, each party hereto hereby
agrees (which agreement shall survive the termination of this Agreement) that,
prior to the date that is one year and one day after the payment in full of all
outstanding commercial paper or other senior indebtedness of any SPC, it will
not institute against, or join any other person in instituting against, such
SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings under the laws of the United States or any State thereof.  In
addition, notwithstanding anything to the contrary contained in this Section
8.07, any SPC may (i) with notice to, but without the prior written consent of,
the Borrower and the Administrative Agent and without paying any processing fee
therefor, assign all or a portion of its interests in any Advances to the
Granting Bank or to any financial institutions (consented to by the Borrower
and Administrative Agent) providing liquidity and/or credit support to or for
the account of such SPC to support the funding or maintenance of Advances and
(ii) disclose on a confidential basis any non-public information relating to
its Advances to any rating agency, commercial paper dealer or provider of any
surety, guarantee or credit or liquidity enhancement to such SPC.

                 SECTION 8.08.  GOVERNING LAW.  THIS AGREEMENT SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
YORK.

                 SECTION 8.09.  Exceptions to Covenants.  The Borrower may not
take or fail to take any action that is permitted as an exception to any of the
covenants contained in any Loan Paper if that action or omission would result
in the breach of any other covenant contained in any Loan Paper.





<PAGE>   48
                                                                              44

                 SECTION 8.10.  Survival.  All covenants, agreements,
undertakings, representations and warranties made in any of the Loan Papers
survive all closings under the Loan Papers until payment in full of the
Obligation and termination of this Agreement, except that Sections 2.11, 2.12,
2.15, 7.05, 8.04 and 8.15 (together with any other provisions in the Loan
Papers which expressly provides that it shall survive termination of this
Agreement) shall survive termination of this Agreement; and such covenants,
agreements, undertakings, representations and warranties, except as otherwise
indicated, are not affected by any investigation made by any party.

                 SECTION 8.11.  Invalid Provisions.  Any provision in any Loan
Paper held to be illegal, invalid, or unenforceable is fully severable; the
appropriate Loan Paper shall be construed and enforced as if that provision had
never been included; and the remaining provisions shall remain in full force
and effect and shall not be affected by the severed provision.  Administrative
Agent, Banks and the Borrower party to the affected Loan Paper agree to
negotiate in good faith the terms of a replacement provision as similar to the
severed provision as may be possible and be legal, valid and enforceable.

                 SECTION 8.12.  Maximum Rate.  Regardless of any provision
contained in any Loan Paper, no Bank shall ever be entitled to contract for,
charge, take, reserve, receive or apply as interest on the Obligation, or any
part thereof, any amount in excess of the Maximum Rate, and, if Banks ever do
so, then any excess shall be deemed a partial prepayment of principal and
treated hereunder as such and any remaining excess shall be refunded to the
Borrower. In determining if the interest paid or payable exceeds the Maximum
Rate, the Borrower and Banks shall, to the maximum extent permitted under
applicable law, (a) treat all Borrowings as but a single extension of credit
(and Banks and Borrower agree that such is the case and that provision herein
for multiple Borrowings is for convenience only), (b) characterize any
nonprincipal payment as an expense, fee, or premium rather than as interest,
(c) exclude voluntary prepayments and the effects thereof, and (d) amortize,
prorate, allocate, and spread the total amount of interest throughout the
entire contemplated term of the Obligation; provided that if the Obligation is
paid and performed in full prior to the end of the full contemplated term
thereof, and if the interest received for its actual period of existence
thereof exceeds the Maximum Amount, Banks shall refund any excess (and Banks
shall not, to the extent permitted by law, be subject to any penalties provided
by any laws for contracting for, charging, taking, reserving, or receiving
interest in excess of the Maximum Amount).

                 SECTION 8.13.  Execution in Counterparts.  This Agreement may
be executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.

                 SECTION 8.14.  Not in Control.  Nothing in any Loan Paper
gives or may be deemed to give to Administrative Agent or any Bank the right to
exercise control over the Borrower or any Subsidiary's Principal Property,
other assets, affairs or management or to preclude or interfere with the
Borrower or any Subsidiary's compliance with any law or require any act or
omission by the Borrower or any Subsidiary that may be harmful to Persons or
property. Any materiality or substantiality qualifier of any representation,
warranty, covenant, agreement or other provision of any Loan Paper is included
for credit documentation purposes only and does not imply, and shall not be
deemed to mean, that Administrative Agent or any Bank acquiesces in any
noncompliance by the Borrower or any Subsidiary with any law, document, or
otherwise or does not expect the Borrower or any Subsidiary to promptly,
diligently and continuously carry out all appropriate removal, remediation,
compliance, closure or other activities required or appropriate in accordance
with all Environmental Laws.

                 SECTION 8.15.  INDEMNIFICATION.  THE BORROWER SHALL INDEMNIFY,
PROTECT, AND HOLD THE ADMINISTRATIVE AGENT, CHASE SECURITIES INC., EACH BANK,
AND THEIR RESPECTIVE AFFILIATES, PARENTS, AND SUBSIDIARIES, AND EACH OF THE
FOREGOING PARTIES' RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, REPRESENTATIVES,
AGENTS, SUCCESSORS, ASSIGNS, AND ATTORNEYS (COLLECTIVELY, THE "INDEMNIFIED
PARTIES") HARMLESS FROM AND AGAINST ANY AND ALL PRESENT AND FUTURE, KNOWN AND
UNKNOWN, FIXED AND

CONTINGENT, LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS,
JUDGMENTS, SUITS, CLAIMS, AND PROCEEDINGS AND ALL REASONABLE AND NECESSARY
COSTS, EXPENSES (INCLUDING, WITHOUT LIMITATION, ALL REASONABLE ATTORNEYS' FEES
AND LEGAL EXPENSES, AND AMOUNTS PAID IN SETTLEMENT WHETHER OR NOT SUIT IS
BROUGHT), AND DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER (THE "INDEMNIFIED
LIABILITIES") WHICH MAY AT ANY TIME BE IMPOSED ON, INCURRED BY, OR ASSERTED
AGAINST THE INDEMNIFIED PARTIES, IN ANY WAY RELATING TO OR ARISING OUT OF (A)
ANY LOAN PAPERS OR TRANSACTION CONTEMPLATED BY ANY LOAN PAPER (INCLUDING,
WITHOUT LIMITATION, THE ACQUISITION), OR (B) ANY INDEMNIFIED PARTY'S SOLE OR
CONCURRENT ORDINARY NEGLIGENCE ARISING IN CONNECTION WITH ANY LOAN PAPER OR ANY
TRANSACTION CONTEMPLATED BY ANY LOAN PAPER, TO THE EXTENT THAT ANY OF THE
INDEMNIFIED LIABILITIES AS TO ANY INDEMNIFIED PARTY RESULTS, DIRECTLY OR
INDIRECTLY, FROM ANY CLAIM MADE, OR ACTION, SUIT, OR PROCEEDING COMMENCED BY OR
ON BEHALF OF ANY PERSON OTHER THAN BY SUCH INDEMNIFIED PARTY; PROVIDED THAT,
THE BORROWER SHALL HAVE NO OBLIGATION HEREUNDER TO ANY INDEMNIFIED PARTY WITH
RESPECT TO ANY INDEMNIFIED LIABILITY ARISING FROM THE FRAUD, GROSS NEGLIGENCE,
OR WILFUL MISCONDUCT OF SUCH INDEMNIFIED PARTY OR ANY ASSOCIATED PERSON OF SUCH
INDEMNIFIED PARTY.  AS USED IN THIS PARAGRAPH, THE TERM "ASSOCIATED PERSON"
MEANS, WITH RESPECT TO ANY PERSON, THE AFFILIATES, PARENTS, SUBSIDIARIES,
DIRECTORS, OFFICERS, EMPLOYEES, REPRESENTATIVES, AGENTS, SUCCESSORS, ASSIGNS,
AND ATTORNEYS OF SUCH PERSON, OR OF ANOTHER PERSON OF WHICH SUCH PERSON IS ALSO
AN ASSOCIATED PERSON.  THE PROVISIONS OF AND UNDERTAKINGS AND INDEMNIFICATION
SET FORTH IN THIS SECTION SHALL SURVIVE THE SATISFACTION AND PAYMENT OF THE
OBLIGATION AND TERMINATION OF THIS AGREEMENT.  THE BORROWER MAY, AT ITS OWN
COST AND EXPENSE, PARTICIPATE IN THE DEFENSE IN ANY PROCEEDING INVOLVING ANY
INDEMNIFIED LIABILITY.  IF NO EVENT OF DEFAULT EXISTS, THE BORROWER MAY ASSUME
THE DEFENSE IN THAT PROCEEDING ON BEHALF OF THE APPLICABLE INDEMNIFIED PARTIES,
INCLUDING THE EMPLOYMENT OF COUNSEL IF FIRST APPROVED (WHICH APPROVAL MAY NOT
BE UNREASONABLY WITHHELD) BY THE APPLICABLE INDEMNIFIED PARTIES.  IF THE
BORROWER ASSUMES ANY DEFENSE, IT SHALL KEEP THE APPLICABLE INDEMNIFIED PARTIES
FULLY ADVISED OF THE STATUS OF, AND SHALL CONSULT WITH THOSE INDEMNIFIED
PARTIES BEFORE TAKING ANY MATERIAL POSITION IN RESPECT OF, THAT PROCEEDING.  IF
THE BORROWER CONSENTS OR IF ANY INDEMNIFIED PARTY REASONABLY DETERMINES THAT AN
ACTUAL CONFLICT OF INTEREST EXISTS BETWEEN THE BORROWER AND THAT INDEMNIFIED
PARTY WITH RESPECT TO THE SUBJECT MATTER OF THE PROCEEDING OR THAT THE BORROWER
IS NOT DILIGENTLY PURSUING THE DEFENSE, THEN (I) THAT INDEMNIFIED PARTY MAY, AT
THE BORROWER'S EXPENSE, EMPLOY COUNSEL TO REPRESENT INDEMNIFIED PARTY THAT IS
SEPARATE FROM COUNSEL FOR THE BORROWER OR ANY OTHER PERSON IN THAT PROCEEDING
AND (II) THE BORROWER IS NO LONGER ENTITLED TO ASSUME THE DEFENSE ON BEHALF OF
THAT INDEMNIFIED PARTY.  THE BORROWER MAY NOT AGREE TO THE SETTLEMENT OF ANY
INDEMNIFIED LIABILITY WITHOUT THE PRIOR WRITTEN CONSENT OF THE APPLICABLE
INDEMNIFIED PARTIES UNLESS THAT SETTLEMENT FULLY RELIEVES THOSE INDEMNIFIED
PARTIES OF ANY LIABILITY WHATSOEVER FOR THAT INDEMNIFIED LIABILITY.

                 SECTION 8.16.  ENTIRETY.  THE LOAN PAPERS REPRESENT THE FINAL
AGREEMENT BETWEEN THE BORROWER, BANKS AND ADMINISTRATIVE AGENT AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL
AGREEMENTS BY SUCH PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN SUCH
PARTIES.

                 SECTION 8.17.  WAIVER OF JURY TRIAL.  EACH PARTY HERETO HEREBY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY
HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING
OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY
(WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY).  EACH PARTY HERETO (A)
CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE
EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES
THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS
AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS
SECTION.


                 IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be executed by their respective officers thereunto duly
