     SECTION 2.1 Loans.  Subject to the terms and  conditions  set forth herein,
each Lender  severally  agrees to make loans (each such loan,  a " Loan") to the
Borrower  from time to time on any  Business  Day  during  the  period  from the
Closing Date to the Maturity  Date, in an aggregate  amount not to exceed at any
time  outstanding  the  lesser  of (x)  such  Lender's  Percentage  Share of the
aggregate  amount of the Loans requested by the Borrower on such day and (y) the
amount of such Lender's Commitment;  provided, however, that after giving effect
to any  borrowing,  (i) the  aggregate  Outstanding  Amount of all Loans and L/C

                                       21


Obligations shall not exceed the lesser of (A) the Aggregate Commitments on such
date  and (B)  the  Borrowing  Base  then  in  effect  and  (ii)  the  aggregate
Outstanding  Amount of the Loans of any Lender,  plus such  Lender's  Percentage
Share of the  Outstanding  Amount of all L/C  Obligations  shall not exceed such
Lender's  Commitment or such Lender's  Percentage  Share of the Borrowing  Base.
Within the limits of each  Lender's  Commitment,  and subject to the other terms
and conditions  hereof,  the Borrower may borrow under this Section 2.1,  prepay
under Section 2.4 and reborrow under this Section 2.1.

     SECTION 2.2 Borrowings, Conversions and Continuations of Loans.

     (a) Each  Borrowing,  each  conversion of Loans from one Type to the other,
and  each  continuation  of  Loans  as the  same  Type  shall  be made  upon the
Borrower's  irrevocable prior written notice to the Administrative  Agent in the
form  of a  Notice  of  Advance.  Each  such  notice  must  be  received  by the
Administrative Agent not later than 12:00 p.m., central time, (i) three Business
Days  prior  to  the  requested  date  of any  Borrowing  of,  conversion  to or
continuation  of LIBO Rate Loans or of any conversion of LIBO Rate Loans to Base
Rate Loans,  and (ii) on the requested date of any Borrowing of Base Rate Loans.
Each  Notice  of  Advance  shall be  appropriately  completed  and  signed  by a
Responsible  Officer  of the  Borrower.  Each  Borrowing  of,  conversion  to or
continuation of LIBO Rate Loans shall be in a principal  amount of $1,000,000 or
a  whole  multiple  of  $1,000,000  in  excess  thereof.  Each  Borrowing  of or
conversion  to Base Rate Loans shall be in a  principal  amount of $500,000 or a
whole  multiple  of  $100,000 in excess  thereof.  Each Notice of Advance  shall
specify (i) whether the  Borrower is  requesting a  Borrowing,  a conversion  of
Loans from one Type to the other,  or a continuation  of Loans as the same Type,
(ii) the requested date of the  Borrowing,  conversion or  continuation,  as the
case may be (which shall be a Business Day), (iii) the principal amount of Loans
to be borrowed, converted or continued, (iv) the Type of Loans to be borrowed or
to which existing Loans are to be converted, and (v) if applicable, the duration
of the Interest Period with respect thereto.  If the Borrower fails to specify a
Type of Loan in a Notice of  Advance or if the  Borrower  fails to give a timely
notice requesting a conversion or continuation,  then the applicable Loans shall
be made or continued  as, or converted to, Base Rate Loans.  Any such  automatic
conversion  to Base  Rate  Loans  shall be  effective  as of the last day of the
Interest  Period then in effect with respect to the applicable  LIBO Rate Loans.
If the Borrower  requests a Borrowing of, conversion to, or continuation of LIBO
Rate Loans in any such  Notice of  Advance,  but fails to  specify  an  Interest
Period, it will be deemed to have specified an Interest Period of one month.

     (b)  Following  receipt of a Notice of Advance,  the  Administrative  Agent
shall  promptly  notify each Lender of its  Percentage  Share of the  applicable
Loans,  and if no timely notice of a conversion or  continuation  is provided by
the Borrower,  the Administrative  Agent shall notify each Lender of the details
of any  automatic  conversion  to Base Rate  Loans  described  in the  preceding
subsection.  Each  Lender  shall  make the amount of its Loan  available  to the
Administrative  Agent  in  immediately  available  funds  at the  Administrative
Agent's  Office not later than 2:00 p.m.  central  time,  on the  Business  Day
specified  in  the  applicable  Notice  of  Advance.  Upon  satisfaction  of the
applicable  conditions  set forth in Section 4.2 (and, if such  Borrowing is the

                                       22



initial Credit Extension,  Section 4.1), the Administrative Agent shall make all
funds so  received  available  to the  Borrower in like funds as received by the
Administrative  Agent either by (i) crediting the account of the Borrower on the
books of TD with the amount of such funds or (ii) wire  transfer  of such funds,
in each case in  accordance  with  instructions  provided to the  Administrative
Agent by the Borrower;  provided, however, that if, on the date of the Borrowing
there are L/C Borrowings outstanding,  then the proceeds of such Borrowing shall
be  applied,  first,  to the  payment  in full of any such L/C  Borrowings,  and
second, to the Borrower as provided above. Unless the Administrative Agent shall
have  received  prompt  notice  from a Lender  that  such  Lender  will not make
available to the  Administrative  Agent such Lender's Loans, the  Administrative
Agent  may in its  discretion  assume  that  such  Lender  has made  such  Loans
available to the  Administrative  Agent in accordance  with this section and the
Administrative  Agent may if it chooses, in reliance upon such assumption,  make
such Loan available to the Borrower.  If and to the extent such Lender shall not
so make its Loan  available  to the  Administrative  Agent,  such Lender and the
Borrower severally agree to pay or repay to the Administrative  Agent within two
Business  Days  after  demand  the amount of such Loan  together  with  interest
thereon,  for  each  day from the date  such  amount  is made  available  to the
Borrower  until  the date such  amount  is paid or repaid to the  Administrative
Agent,  to be calculated as to such Lender at the Federal Funds Rate,  and to be
calculated as to the Borrower at the interest rate applicable at the time to the
other Loans made on such date.  If any Lender  fails to make such payment to the
Administrative  Agent within such two Business Day period,  such Lender shall in
addition to such amount pay  interest  thereon,  for each day from the date such
Loan is made  available  to the  Borrower  until the date such amount is paid or
repaid to the Administrative  Agent, at the interest rate applicable at the time
to the other Loans made on such date. The failure of any Lender to make any Loan
to be made by it hereunder  shall not relieve any other Lender of its obligation
hereunder,  if any, to make its Loan, but no Lender shall be responsible for the
failure of any other Lender to make any Loan to be made by such other Lender.

     (c) Except as otherwise  provided herein, a LIBO Rate Loan may be continued
or  converted  only on the last day of the  Interest  Period  for such LIBO Rate
Loan.  During the  existence of a Default,  Event of Default or  Borrowing  Base
Deficiency, no Loans may be requested as, converted to or continued as LIBO Rate
Loans.

     (d) The  Administrative  Agent shall  promptly  notify the Borrower and the
Lenders of the interest rate applicable to any LIBO Rate Loan upon determination
of such interest rate. The determination of the LIBO Rate by the  Administrative
Agent shall be conclusive in the absence of manifest error.  The  Administrative
Agent shall notify the Borrower and the Lenders of any change in TD's prime rate
used in determining the Base Rate promptly following the public  announcement of
such change.

     (e) After giving effect to all  Borrowings,  all  conversions of Loans from
one Type to the other,  and all  continuations  of Loans as the same Type, there
shall not be more than ten LIBO  Interest  Periods  in effect  with  respect  to
Loans.

          or denominated in a currency other than Dollars; or

          with  all  applicable   governmental   restrictions,   policies,   and
          guidelines (whether or not having the force of law) or it subjects the
          Issuing  Bank to any cost not  anticipated  by the Issuing Bank on the
          date hereof;

                                       24



               (G)  the  form  and  terms  of  such  Letter  of  Credit  are not
          acceptable to the Administrative  Agent and Issuing Bank in their sole

     (iii) The Issuing Bank shall be under no  obligation to amend any Letter of

such Letter of Credit in its  amended  form under the terms  hereof,  or (B) the

such Letter of Credit.

Issuing  Bank will  confirm with the  Administrative  Agent (by  telephone or in
writing)  that the  Administrative  Agent has  received a copy of such Letter of
Credit  Application from the Borrower and, if not, the Issuing Bank will provide
the Administrative  Agent with a copy thereof.  Upon receipt by the Issuing Bank
of confirmation  from the  Administrative  Agent that the requested  issuance or
amendment is permitted in accordance with the terms hereof, then, subject to the
terms and  conditions  hereof,  the Issuing Bank shall,  on the requested  date,
issue a Letter of Credit  for the  account  of the  Borrower  or enter  into the
applicable  amendment,  as the case may be, in each case in accordance  with the
Issuing  Bank's usual and customary  business  practices.  Immediately  upon the
issuance  of each Letter of Credit,  each Lender  shall be deemed to, and hereby

                                       25


irrevocably  and  unconditionally  agrees to and hereby does,  purchase from the
Issuing Bank a participation  in such Letter of Credit in an amount equal to the
product of such  Lender's  Percentage  Share  times the amount of such Letter of
Credit.

2.3.3 Drawings and Reimbursements; Funding of Participations.

     (i) Upon any drawing  under any Letter of Credit,  the  Issuing  Bank shall
notify the Borrower and the Administrative  Agent thereof.  Not later than 12:00
p.m.,  central  time,  on the date of any  payment by the  Issuing  Bank under a
Letter of Credit (each such date, an "Honor Date"), the Borrower shall reimburse
the Issuing  Bank  through the  Administrative  Agent in an amount  equal to the
amount of such drawing.  If the Borrower  fails to so reimburse the Issuing Bank
by such time, the Administrative  Agent shall promptly notify each Lender of the
Honor Date, the amount of the unreimbursed drawing (the "Unreimbursed  Amount"),
and such Lender's Percentage Share thereof. In such event, the Borrower shall be
deemed to have  requested a Borrowing  of Base Rate Loans to be disbursed on the
Honor Date in an amount equal to the Unreimbursed Amount,  without regard to the
minimum and multiples  specified in Section 2.2 for the principal amount of Base
Rate Loans, but subject to the amount of the unutilized portion of the lesser of
(x) the Aggregate  Commitments and (y) the Borrowing Base then in effect and the
conditions  set forth in Section  4.2 (other  than the  delivery  of a Notice of
Advance).  Any notice  given by the  Issuing  Bank or the  Administrative  Agent
pursuant to this  Section  2.3.3(i)  may be given by  telephone  if  immediately
confirmed in writing;  provided that the lack of such an immediate  confirmation
shall not affect the conclusiveness or binding effect of such notice.

     (ii) Each Lender  (including  the Lender acting as Issuing Bank) shall upon
any notice from the Administrative Agent pursuant to Section 2.3.3(i) make funds
available to the Administrative Agent for the account of the Issuing Bank at the
Administrative  Agent's  Office in an amount equal to such  Lender's  Percentage
Share of the Unreimbursed  Amount not later than 1:00 p.m., central time, on the
Business Day specified in such notice by the  Administrative  Agent,  whereupon,
subject to the provisions of Section 2.3.3(iii), each Lender that so makes funds
available  shall be deemed to have made a Base Rate Loan to the Borrower in such
amount.  The  Administrative  Agent  shall  remit the funds so  received  to the
Issuing Bank.

     (iii) With respect to any Unreimbursed  Amount that is not fully refinanced
by a Borrowing of Base Rate Loans  because the  conditions  set forth in Section
4.2 cannot be satisfied or for any other reason, the Borrower shall be deemed to
have  incurred  from the  Issuing  Bank an L/C  Borrowing  in the  amount of the
Unreimbursed Amount that is not so refinanced,  which L/C Borrowing shall be due
and payable on demand  (together  with  interest) and shall bear interest at the
Default Rate. In such event, each Lender's payment to the  Administrative  Agent
for the  account of the Issuing  Bank  pursuant  to Section  2.3.3(ii)  shall be
deemed payment in respect of its  participation  in such L/C Borrowing and shall
constitute an L/C Advance from such Lender in satisfaction of its  participation
obligation under this Section 2.3.3.

     (iv) Until  each  Lender  funds its Loan or L/C  Advance  pursuant  to this
Section  2.3.3 to  reimburse  the  Issuing  Bank for any amount  drawn under any

                                     26



Letter of Credit,  interest in respect of such Lender's Percentage Share of such
amount shall be solely for the account of the Issuing Bank.

     (v) Each Lender's obligation to make Loans or L/C Advances to reimburse the
Issuing Bank for amounts drawn under Letters of Credit,  as contemplated by this
Section 2.3.3,  shall be absolute and unconditional and shall not be affected by
any circumstance,  including (A) any set-off, counterclaim,  recoupment, defense
or other right which such Lender may have against the Issuing Bank, the Borrower
or any other Person for any reason whatsoever; (B) the occurrence or continuance
of a  Default  or  Event  of  Default,  or (C) any  other  occurrence,  event or
condition,   whether  or  not  similar  to  any  of  the  foregoing.   Any  such
reimbursement  shall not  relieve  or  otherwise  impair the  obligation  of the
Borrower to reimburse the Issuing Bank for the amount of any payment made by the
Issuing  Bank under any Letter of Credit,  together  with  interest  as provided
herein.

     (vi) If any Lender fails to make available to the Administrative  Agent for
the  account of the Issuing  Bank any amount  required to be paid by such Lender
pursuant to the foregoing provisions of this Section 2.3.3 by the time specified
in Section  2.3.3(ii),  the Issuing  Bank shall be entitled to recover from such
Lender (acting through the  Administrative  Agent), on demand,  such amount with
interest  thereon for the period  from the date such  payment is required to the
date on which such  payment is  immediately  available  to the Issuing Bank at a
rate  per  annum  equal  to (1) for the  first  two  Business  Days  immediately
following the date such payment is required, the Federal Funds Rate from time to
time in effect, and (2) for each day thereafter, the Base Rate from time to time
in effect.  A certificate of the Issuing Bank  submitted to any Lender  (through
the  Administrative  Agent) with respect to any amounts  owing under this clause
(vi) shall be conclusive absent manifest error.

2.3.4 Repayment of Participations.

     (i) At any time after the Issuing Bank has made a payment  under any Letter
of Credit and has received  from any Lender such Lender's L/C Advance in respect
of such payment in accordance  with Section 2.3.3, if the  Administrative  Agent
receives for the account of the Issuing Bank any payment  related to such Letter
of Credit (whether directly from the Borrower or otherwise,  including  proceeds
of Cash Collateral applied thereto by the Administrative  Agent), or any payment
of interest thereon, the Administrative Agent will distribute to such Lender its
Percentage   Share  thereof  in  the  same  funds  as  those   received  by  the
Administrative Agent.

     (ii) If any payment received by the Administrative Agent for the account of
the Issuing  Bank  pursuant to Section  2.3.3 is required to be  returned,  each
Lender shall pay to the Administrative Agent for the account of the Issuing Bank
its  Percentage  Share  thereof  on demand  of the  Administrative  Agent,  plus
interest  thereon  from  the date of such  demand  to the date  such  amount  is
returned by such  Lender,  at a rate per annum equal to (1) with  respect to the
first two Business Days  immediately  following  such demand,  the Federal Funds
Rate from time to time in effect,  and (2) with respect to each day  thereafter,
the Base Rate from time to time in effect.

                                       27




     2.3.5 Obligations Absolute. The obligation of the Borrower to reimburse the
Issuing Bank for each drawing under each Letter of Credit, and to repay each L/C
Borrowing  and each  drawing  under a Letter of Credit that is  refinanced  by a
Borrowing of Loans, shall be absolute,  unconditional and irrevocable, and shall
be paid  strictly  in  accordance  with the  terms of this  Agreement  under all
circumstances, including the following:

          (i) any lack of validity or  enforceability  of such Letter of Credit,
     this Agreement, or any other agreement or instrument relating thereto;

          (ii) the  existence of any claim,  counterclaim,  set-off,  defense or
     other right that the Borrower may have at any time against any  beneficiary
     or any transferee of such Letter of Credit (or any Person for whom any such
     beneficiary or any such transferee may be acting),  the Issuing Bank or any
     other Person,  whether in connection with this Agreement,  the transactions
     contemplated  hereby  or by such  Letter  of  Credit  or any  agreement  or
     instrument relating thereto, or any unrelated transaction;

          (iii) any draft, demand, certificate or other document presented under
     such  Letter  of  Credit  proving  to be  forged,  fraudulent,  invalid  or
     insufficient  in any  respect  or any  statement  therein  being  untrue or
     inaccurate  in any  respect;  or any loss or delay in the  transmission  or
     otherwise  of any document  required in order to make a drawing  under such
     Letter of Credit;

          (iv) any  payment by the  Issuing  Bank  under  such  Letter of Credit
     against  presentation  of a draft or  certificate  that  does not  strictly
     comply with the terms of such Letter of Credit;  or any payment made by the
     Issuing Bank under such Letter of Credit to any Person  purporting  to be a
     trustee in  bankruptcy,  debtor-in-possession,  assignee for the benefit of
     creditors,  liquidator, receiver or other representative of or successor to
     any  beneficiary or any transferee of such Letter of Credit,  including any
     arising in connection with any proceeding under any Debtor Relief Law; or

          (v) any other  circumstance  or happening  whatsoever,  whether or not
     similar to any of the  foregoing,  including  any other  circumstance  that
     might otherwise  constitute a defense  available to, or a discharge of, the
     Borrower.

          The Borrower  shall  promptly  examine a copy of each Letter of Credit
     and each amendment thereto that is delivered to it and, in the event of any
     claim  of   noncompliance   with  the  Borrower's   instructions  or  other
     irregularity,  the Borrower  will  promptly  notify the Issuing  Bank.  The
     Borrower shall be conclusively deemed to have waived any such claim against
     the  Issuing  Bank and its  correspondents  unless  such notice is given as
     aforesaid.

     2.3.6 Role of Issuing Bank;  Indemnity.  Each Lender and the Borrower agree
that, in paying any drawing under a Letter of Credit, the Issuing Bank shall not
have any  responsibility  to obtain any  document  (other than any sight  draft,
certificates  and  documents  expressly  required by the Letter of Credit) or to
ascertain or inquire as to the validity or accuracy of any such  document or the
authority  of  the  Person  executing  or  delivering  any  such  document.   No
Agent-Related Person nor any of the respective  correspondents,  participants or

                                     28

assignees  of the Issuing  Bank shall be liable to any Lender for (i) any action
taken or omitted in  connection  herewith at the request or with the approval of
the Lenders or the Majority  Lenders,  as  applicable;  (ii) any action taken or
omitted in the absence of gross negligence or willful  misconduct;  or (iii) the
due  execution,  effectiveness,  validity or  enforceability  of any document or
instrument related to any Letter of Credit or Letter of Credit Application.  The
Borrower hereby assumes all risks of the acts or omissions of any beneficiary or
transferee  with  respect to its use of any Letter of Credit.  No  Agent-Related
Person, nor any of the respective  correspondents,  participants or assignees of
the  Issuing  Bank,  shall  be  liable  or  responsible  for any of the  matters
described in clauses (i) through (v) of Section  2.3.5.  The Borrower  agrees to
hold Issuing Bank and each Lender harmless and indemnified against any liability
or claim  in  connection  with or  arising  out of the  subject  matter  of this
section,  WHICH INDEMNITY SHALL APPLY WHETHER OR NOT ANY SUCH LIABILITY OR CLAIM
IS IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT
OR OMISSION OF ANY KIND BY ISSUING  BANK OR ANY LENDER,  provided  only that the
Issuing  Bank or such Lender shall not be entitled to  indemnification  for that
portion,  if any, of any liability or claim which is  proximately  caused by its
own individual gross  negligence or willful  misconduct as determined in a final
judgment.  In furtherance  and not in limitation of the  foregoing,  the Issuing
Bank may accept  documents  that  appear on their  face to be in order,  without
responsibility   for  further   investigation,   regardless  of  any  notice  or
information to the contrary,  and the Issuing Bank shall not be responsible  for
the  validity or  sufficiency  of any  instrument  transferring  or assigning or
purporting  to  transfer  or assign a Letter of Credit or the rights or benefits
thereunder  or  proceeds  thereof,  in whole or in part,  which  may prove to be
invalid or ineffective for any reason.  If any Letter of Credit provides that it
is  transferable,  the Issuing Bank shall have no duty to  determine  the proper
identity of anyone  appearing as transferee of such Letter of Credit,  nor shall
the Issuing Bank be charged with  responsibility  of any nature or character for
the validity or correctness of any transfer or successive transfers, and payment
by the Issuing Bank to any purported  transferee or transferees as determined by
the Issuing Bank is hereby  authorized  and approved,  and the Borrower  further
agrees to hold the Issuing Bank and each Lender harmless and indemnified against
any liability or claim in connection with or arising out of the foregoing, WHICH
INDEMNITY  SHALL APPLY WHETHER OR NOT ANY SUCH  LIABILITY OR CLAIM IS IN ANY WAY
OR TO ANY EXTENT  CAUSED,  IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION
OF ANY KIND BY THE ISSUING  BANK OR ANY LENDER,  provided  only that the Issuing
Bank or such Lender shall not be entitled to  indemnification  for that portion,
if any, of any  liability or claim which is caused by its own  individual  gross
negligence  or willful  misconduct.  All of  Borrower's  Obligations  under this
Section 2.3.6 shall survive  termination of the Commitments or of this Agreement
and repayment in full of the Obligations.

     2.3.7  Applicability of ISP98 and UCP. Unless otherwise expressly agreed by
the Issuing  Bank and the  Borrower  when a Letter of Credit is issued,  (i) the
rules of the  "International  Standby Practices 1998" published by the Institute
of International Banking Law & Practice (or such later version thereof as may be
in effect at the time of issuance) shall apply to each standby Letter of Credit,
and (ii) the rules of the Uniform Customs and Practice for Documentary  Credits,
as most recently published by the International  Chamber of Commerce (the "ICC")
at the time of issuance  (including the ICC decision published by the Commission

                                       29



on Banking Technique and Practice on April 6, 1998 regarding the European single
currency (euro)) shall apply to each commercial Letter of Credit.

     2.3.8 Letter of Credit Fees. The Borrower  shall pay to the  Administrative
Agent for the account of each Lender in accordance  with its Percentage  Share a
Letter of Credit fee for each Letter of Credit equal to the LIBOR Spread then in
effect with respect to Loans after giving effect to the L/C Obligations incurred
with  respect to such Letter of Credit  times the actual  daily  maximum  amount
available  to be drawn under such Letter of Credit.  Such fee for each Letter of
Credit shall be due and payable on the last  Business  Day of each March,  June,
September and December,  commencing  with the first such date to occur after the
issuance  of such  Letter of Credit,  and on the  Letter of Credit  Availability
Expiration  Date. If there is any change in the LIBOR Spread during any quarter,
the  actual  daily  amount  of each  Letter  of  Credit  shall be  computed  and
multiplied by the LIBOR Spread with respect to Letters of Credit  separately for
each period during such quarter that such LIBOR Spread was in effect.

     2.3.9 Letter of Credit Fronting Fee and Documentary and Processing  Charges
Payable to Issuing Bank. The Borrower shall pay directly to the Issuing Bank for
its own  account a  fronting  fee in an  amount  equal to 0.25% per annum on the
daily maximum amount available to be drawn thereunder, due and payable quarterly
in arrears on the last Business Day of each March, June, September and December,
commencing  with the first such date to occur after the  issuance of such Letter
of Credit, and on the Letter of Credit  Availability  Expiration Date;  provided
that all  such  fees  shall be  payable  on the  date on which  the  Commitments
terminate  and any such fees  accruing  after the date on which the  Commitments
terminate  shall be payable on  demand.  In  addition,  the  Borrower  shall pay
directly  to the  Issuing  Bank  for its own  account  the  customary  issuance,
presentation,  amendment and other processing fees, and other standard costs and
charges,  of the Issuing Bank relating to letters of credit as from time to time
in  effect.  Such  fees  and  charges  are due and  payable  on  demand  and are
nonrefundable. All participation fees and fronting fees shall be computed on the
basis of a year of 360 days and shall be payable  for the actual  number of days
elapsed (including the first day but excluding the last day).

     2.3.10  Conflict  with  Letter of Credit  Application.  In the event of any
conflict  between  the  terms  hereof  and the  terms of any  Letter  of  Credit
Application, the terms hereof shall control.

     2.3.11 L/C Collateral.

     (a) L/C  Obligations  in Excess of Borrowing  Base or upon  Termination  of
Commitments.  (i) If,  after the making of all  mandatory  prepayments  required
under Section 2.4.2, the aggregate amount of all Loans  outstanding plus all L/C
Obligations  outstanding  excluding L/C  Obligations  secured by cash collateral
pursuant  to this  Section  2.3.11  will  exceed the  Borrowing  Base,  then the
Borrower  will  immediately  pay to the Issuing  Bank an amount in cash equal to
such  excess,  or (ii)  should any L/C  Obligations  remain  outstanding  on the
Maturity Date, then the Borrower will immediately pay the Issuing Bank an amount
in cash equal to the aggregate  amount of such Issuing  Bank's L/C  Obligations.
The  Issuing  Bank will  hold such  amount as  security  for the  remaining  L/C
Obligations  ("L/C  Collateral")  until such L/C Obligations  become Matured L/C
Obligations,  at which time such L/C  Collateral  may be applied to such Matured

                                       30



L/C  Obligations.  Neither this subsection nor the following  subsection  shall,
however,  limit or impair any rights  which the Issuing  Bank may have under any
other document or agreement  relating to any Letter of Credit or L/C Obligation,
including any Letter of Credit of  Application,  or any rights which the Issuing
Bank or Lenders may have to otherwise apply any payments by the Borrower and L/C
Collateral under Section 2.3.11.

     (b) Acceleration of L/C Obligations. If the Obligations or any part thereof
become  immediately  due and payable  pursuant  to Section 8.2 then,  unless the
Majority Lenders  otherwise  specifically  elect to the contrary (which election
may  thereafter  be  retracted  by the  Majority  Lenders at any time),  all L/C
Obligations  shall become  immediately due and payable without regard to whether
or not actual  drawings or payments on the Letters of Credit have occurred,  and
the Borrower shall be obligated to pay to the Issuing Bank immediately an amount
equal to the aggregate L/C Obligations which are then  outstanding.  All amounts
so paid shall first be applied to Matured L/C  Obligations  and then held by the
Issuing Bank as L/C  Collateral  until such L/C  Obligations  become Matured L/C
Obligations,  at which time such L/C Collateral shall be applied to such Matured
L/C Obligations.

     (c) Investment of L/C  Collateral.  Pending  application  thereof,  all L/C
Collateral  shall  be  invested  by the  Issuing  Bank in such  interest-bearing
investments  as the Issuing  Bank may choose in its sole  discretion  reasonably
exercised.  All interest on such  investments  shall be reinvested or applied to
Matured L/C  Obligations.  When all  Obligations  have been  satisfied  in full,
including  all L/C  Obligations,  all  Letters  of Credit  have  expired or been
terminated,  and all of the Borrower's  reimbursement  obligations in connection
therewith  have been  satisfied  in full,  the  Issuing  Bank shall  release any
remaining L/C Collateral.  The Borrower hereby assigns and grants to the Issuing
Bank a  continuing  security  interest in all L/C  Collateral  paid by it to the
Issuing  Bank,  all  investments  purchased  with such L/C  Collateral,  and all
proceeds thereof to secure its Matured L/C Obligations and its Obligations under
this Agreement, the Notes, and the other Loan Documents, and the Borrower agrees
that such L/C  Collateral and  investments  shall be subject to all of the terms
and  conditions of the Mortgage.  The Borrower  further  agrees that the Issuing
Bank  shall have all of the rights and  remedies  of a secured  party  under the
Uniform Commercial Code as adopted in the State of New York with respect to such
security  interest  and that an Event of  Default  under  this  Agreement  shall
constitute a default for purposes of such security interest.

     2.3.12  Calculations.  A written advice setting forth in reasonable  detail
the  amounts  owing under this  section,  submitted  by the Issuing  Bank to the
Borrower or any Lender from time to time,  shall be conclusive,  absent manifest
error, as to the amounts thereof.

     SECTION 2.4 Prepayments.

     2.4.1  Voluntary  Prepayments.   The  Borrower  may,  upon  notice  to  the
Administrative  Agent, at any time or from time to time voluntarily prepay Loans
in whole or in part without  premium or penalty;  provided  that (i) such notice
must be received by the Administrative  Agent not later than 12:00 p.m., central
time,  (A) three  Business  Days  prior to any date of  prepayment  of LIBO Rate
Loans, and (B) on the date of prepayment of Base Rate Loans; (ii) any prepayment
of LIBO Rate  Loans  shall be in a  principal  amount of  $1,000,000  or a whole
multiple of $1,000,000 in excess thereof;  and (iii) any prepayment of Base Rate
Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000
in excess  thereof.  Each such notice shall  specify the date and amount of such

                                     31



prepayment and the Type(s) of Loans to be prepaid. The Administrative Agent will
promptly  notify  each Lender of its  receipt of each such  notice,  and of such
Lender's  Percentage  Share of such  prepayment.  If such notice is given by the
Borrower,  the  Borrower  shall  make such  prepayment  and the  payment  amount
specified in such notice shall be due and payable on the date specified therein.
Any prepayment of a LIBO Rate Loan shall be accompanied by all accrued  interest
thereon,  together with any additional amounts required pursuant to Section 3.5.
Each such prepayment  shall be applied to the Loans of the Lenders in accordance
with their respective Percentage Shares.

     2.4.2  Mandatory  Prepayments.   The  Borrower  shall  make  the  following
prepayments of the Loans:

          (i) Outstandings Exceed Commitments. If for any reason the Outstanding
     Amount of all Loans and L/C  Obligations  at any time exceeds the Aggregate
     Commitments  then in effect,  the Borrower shall first  immediately  prepay
     Loans and second following  repayment of the Loans, Cash  Collateralize the
     L/C Obligations in an aggregate amount equal to such excess.

          (ii) Borrowing Base Deficiency.

               (A) If at any time the aggregate unpaid principal  balance of the
          Loans  plus  the  aggregate  amount  of L/C  Obligations  exceeds  the
          Borrowing Base (a "Borrowing  Base  Deficiency"),  the Borrower shall,
          within thirty (30) days after the  Administrative  Agent sends written
          notice of such fact to the  Borrower,  (1) prepay the principal of the
          Loans  (and,  upon  prepayment  of all  Loans,  shall,  to the  extent
          required, provide L/C Collateral as set forth in Section 2.3.11) in an
          aggregate  amount at least equal to such Borrowing Base Deficiency (in
          this section, a "Mandatory  Prepayment Amount"), or (2) give notice to
          the Administrative  Agent electing to prepay such Mandatory Prepayment
          Amount  in  three  (3) (or  fewer)  monthly  installments.  Each  such
          installment  shall equal or exceed  one-third of such  Borrowing  Base
          Deficiency;  the first such  installment  shall be paid within  thirty
          (30)  days  of  the  giving  of  such  notice  of the  Borrowing  Base
          Deficiency by the Administrative Agent to the Borrower and the two (or
          fewer) subsequent  installments  shall be due and payable at one month
          intervals  thereafter  until such Borrowing  Base  Deficiency has been
          eliminated.

               (B) If (1) at any time during the existence or  continuation of a
          Borrowing  Base  Deficiency,  the  Borrower or any  Guarantor  makes a
          Disposition  of assets  (other  than those  described  in clauses  (a)
          through (d) of Section 7.5  hereof),  or (2) a  Disposition  of assets
          included in the Borrowing Base results in a reduction of the Borrowing
          Base in  accordance  with  Section  7.5(e) such that a Borrowing  Base
          Deficiency occurs,  then, in either case, the Borrower shall, or shall
          cause  such  Guarantor  to,  use  the  Net  Sale  Proceeds  from  such

                                       32



          Disposition  (whether or not such assets are included in the Borrowing
          Base) to prepay  the Loans and upon  prepayment  of all  Loans,  shall
          provide L/C Collateral as set forth in Section 2.3.11,  within one (1)
          Business  Day of receipt of such Net Sale  Proceeds in an amount equal
          to the lesser of 100% of the Net Sale  Proceeds  from the sale of such
          assets  and the full  amount of the  Borrowing  Base  Deficiency  then
          existing or occurring as a result of such disposition.  Application of
          such Net Sales  Proceeds  shall be applied to the principal  amount of
          the Loans  until the Loans are paid in full and then  shall be held as
          L/C  Collateral  in an  amount  equal to the  aggregate  amount of L/C
          Obligations pursuant to Section 2.3.11.

     SECTION 2.5  Reduction  or  Termination  of  Commitments  and Maximum  Loan
Amount. The Borrower may, upon notice to the Administrative Agent, terminate the
Aggregate  Commitments  and  Maximum  Loan  Amount,  or  permanently  reduce the
Aggregate  Commitments  and  Maximum  Loan Amount to an amount not less than the
then Outstanding Amount of all Loans and L/C Obligations;  provided that (i) any
such notice shall be received by the  Administrative  Agent not later than 12:00
p.m.,  central time three (3) Business Days prior to the date of  termination or
reduction,  and (ii) any such partial  reduction shall be in an aggregate amount
of  $5,000,000  or any whole  multiple  of  $1,000,000  in excess  thereof.  The
Administrative  Agent  shall  promptly  notify the Lenders of any such notice of
reduction or termination of the Aggregate  Commitments  and Maximum Loan Amount.
Once  reduced  in  accordance  with this  Section,  the  Commitments  may not be
increased.  Any reduction of the Aggregate  Commitments  shall be applied to the
Commitment of each Lender according to its Percentage Share. All commitment fees
accrued until the effective date of any termination of the Aggregate Commitments
shall be paid on the effective date of such termination.

     SECTION 2.6 Repayment of Loans.  The Borrower shall repay to the Lenders on
the Maturity Date the aggregate  principal  amount of Loans  outstanding on such
date.

     SECTION 2.7 Initial  Borrowing Base. On any date during the period from the
Closing Date to the first Evaluation Date, the Borrowing Base shall be an amount
equal to (i)  $270,000,000,  less (ii) the principal amount of DevX Senior Notes
then  outstanding,  except in the case of a Loan the  proceeds  of which will be
used to purchase and cancel or redeem and cancel any of the DevX Senior Notes in
each case  pursuant to Section 309 of the DevX  Indenture  as  certified  in the
relevant Notice of Advance.

     SECTION 2.8 Subsequent Determinations of Borrowing Base.

     (a)  By  each   Evaluation   Date,   the  Borrower  shall  furnish  to  the
Administrative Agent and each Lender all information, reports and data which the
Administrative Agent has then reasonably requested concerning the Borrower's and
the  Guarantors'   businesses  and  properties  (including  Borrower's  and  the
Guarantors' Oil and Gas Properties and interests and the reserves and production
relating  thereto),  together with the Engineering  Report  described in Section
6.2(g),  if an  Engineering  Report is then due.  Within  thirty (30) days after
receiving  such  information,  reports and data,  or as promptly  thereafter  as
practicable,  the Administrative Agent shall recommend a redetermined  Borrowing
Base to the Lenders. Such recommended Borrowing Base shall become effective upon
the receipt by the  Administrative  Agent of the  approval  of such  recommended
Borrowing Base by Lenders  holding not less than 75% of the aggregate  amount of

                                     33



the Credit  Extensions then  outstanding (or 75% of the Commitments if no Credit
Extensions are outstanding).  If such recommended Borrowing Base is not approved
by  Lenders  holding  not less than 75% of the  aggregate  amount of the  Credit
Extensions then  outstanding (or 75% of the Commitments if no Credit  Extensions
are then  outstanding)  within  ten (10)  days  after the  Administrative  Agent
submits the  recommended  Borrowing Base to the Lenders,  then each Lender shall
submit in writing to the Administrative  Agent, on or within ten (10) days after
the Administrative Agent notifies the Lenders that the Lenders have not approved
any  such  recommended  Borrowing  Base,  such  Lender's  determination  of  the
redetermined Borrowing Base; in such case, the redetermined Borrowing Base shall
be the  highest  amount  approved  by Lenders  holding  not less than 75% of the
aggregate  amount  of the  Credit  Extensions  then  outstanding  (or 75% of the
Commitments if no Credit Extensions are outstanding).  NOTWITHSTANDING  ANYTHING
HEREIN  TO THE  CONTRARY,  WITHOUT  THE  PRIOR  WRITTEN  APPROVAL  OF ALL OF THE
LENDERS, SUCH APPROVAL TO BE IN EACH LENDER'S SOLE DISCRETION,  THE REDETERMINED
BORROWING BASE SHALL NOT BE INCREASED  ABOVE THE AMOUNT OF THE BORROWING BASE IN
EFFECT IMMEDIATELY PRIOR TO SUCH REDETERMINATION. The Administrative Agent shall
by notice to the Borrower and the Lenders  designate the amount of the Borrowing
Base (determined by Lenders holding not less than 75% of the aggregate amount of
Credit  Extensions  then  outstanding  or 75% of the  Commitments  if no  Credit
Extensions  are  then  outstanding  or all of the  Lenders,  as  applicable,  in
accordance with the foregoing  procedures)  available to the Borrower hereunder,
which designation shall take effect  immediately on the date such notice is sent
(a "Determination  Date") and shall remain in effect until but not including the
next date as of which the Borrowing Base is  redetermined.  If the Borrower does
not furnish all such information,  reports and data by the date specified in the
first  sentence  of this  section,  the  Administrative  Agent  may  nonetheless
designate the Borrowing Base at any amount which the Lenders determine,  and may
redesignate  the Borrowing Base from time to time thereafter at any amount which
all  Lenders  redetermine,  until each  Lender  receives  all such  information,
reports and data,  whereupon  Lenders shall  designate a new  Borrowing  Base as
described  above.  The Lenders shall  determine the amount of the Borrowing Base
based upon the loan collateral value which they, in their sole discretion and in
accordance with their respective  normal practices and standards for oil and gas
loans as such practices and standards  exist at the particular  time,  assign to
the various Oil and Gas Properties of the Borrower or the Guarantors at the time
in question and based upon such other factors  (including without limitation the
assets, liabilities, fixed charges, cash flow, business, properties,  prospects,
management  and  ownership  of any  of the  Borrower  or the  Guarantors  or any
Subsidiary  of any of the  Borrower or the  Guarantors)  as they,  in their sole
discretion  and  in  accordance  with  their  respective  normal  practices  and
standards for oil and gas loans as such  practices  and  standards  exist at the
particular time, deem significant.  It is expressly  understood that Lenders and
the  Administrative  Agent have no  obligation  to agree upon or  designate  the
Borrowing Base at any particular amount, whether in relation to the Maximum Loan
Amount  or  otherwise,  and that  the  Lenders'  commitments  to  advance  funds
hereunder is determined by reference to the Borrowing  Base from time to time in
effect, which Borrowing Base shall be used for calculating commitment fees under
Section 2.10(a) and, to the extent permitted by law and regulatory  authorities,
for the purposes of Section 2.15. Additional  redeterminations at the request of
the Lenders,  the  Administrative  Agent or the  Borrower  shall be subject to a
$5,000 engineering fee payable by Borrower to the  Administrative  Agent for its
own account.

                                       34



     (b) The  Borrower  may include  additional  Oil and Gas  Properties  of the
Borrower or the  Guarantors  acquired  from time to time as  Collateral  for the
Obligations,  which may then be included  in the  calculation  of the  Borrowing
Base, by the Borrower (A) giving written notice to the  Administrative  Agent of
such properties to be included, (B) subjecting such properties to Liens securing
the   Obligations   (pursuant  to  Security   Documents   satisfactory   to  the
Administrative  Agent),  (C) including such properties in an Engineering  Report
submitted to the  Administrative  Agent and (D) delivering to the Administrative
Agent title opinions  covering at least 80% of the additional value addressed to
the  Administrative  Agent for the benefit of the Lenders  covering  all of such
properties   and  other  legal   opinions   from  counsel   acceptable   to  the
Administrative  Agent,  in its sole  discretion,  in form,  scope and  substance
acceptable to the Administrative Agent opining favorably as to, among such other
matters as may be required by the  Administrative  Agent,  (1) the Borrower's or
the appropriate  Guarantor's ownership of such properties and (2) matters of the
type covered by the opinions delivered pursuant to Section 4.1(a)(vi).

     (c) In  addition  to  the  any  scheduled  determination  or  discretionary
determination  of the Borrowing Base, the Borrowing Base shall be  automatically
reduced from time to time as set forth in Section 7.5(e).

     SECTION 2.9 Interest.

     (a) Subject to the provisions of subsection  (b) below,  (i) each LIBO Rate
Loan shall bear interest on the  outstanding  principal  amount thereof for each
Interest  Period at a rate per annum  equal to the  Adjusted  LIBO Rate for such
Interest  Period plus the LIBOR Spread;  and (ii) each Base Rate Loan shall bear
interest  on the  outstanding  principal  amount  thereof  from  the  applicable
borrowing  date at a rate per  annum  equal to the Base  Rate plus the Base Rate
Spread.

     (b) While any Event of Default or Borrowing Base Deficiency exists or after
acceleration,  the Borrower  shall pay interest on the  principal  amount of all
outstanding  Obligations  at a fluctuating  interest rate per annum at all times
equal to the Default Rate to the fullest  extent  permitted by  applicable  Law.
Accrued and unpaid interest on past due amounts (including  interest on past due
interest) shall be due and payable upon demand.

     (c)  Interest  on each Loan  shall be due and  payable  in  arrears on each
Interest  Payment  Date  applicable  thereto  and at such other  times as may be
specified herein. Interest hereunder shall be due and payable in accordance with
the  terms  hereof  before  and  after  judgment,   and  before  and  after  the
commencement of any proceeding under any Debtor Relief Law.

     SECTION 2.10 Fees. In addition to certain fees  described in Sections 2.3.8
and 2.3.9:

     (a) Commitment Fee. The Borrower shall pay to the Administrative  Agent for
the account of each Lender in accordance with its Percentage Share, a commitment
fee equal to the  Commitment Fee Rate times the actual daily amount by which the
Aggregate  Commitments exceed the sum of (i) the Outstanding Amount of Loans and
(ii) the Outstanding Amount of L/C Obligations; provided, however, that from the
Closing Date until the First  Evaluation  Date,  the  Borrower  shall pay to the
Administrative  Agent for the  account  of each  Lender in  accordance  with its

                                       35



Percentage  Share,  a commitment  fee equal to the Commitment Fee Rate times the
actual daily amount by which $270,000,000 exceeds the sum of (i) the Outstanding
Amount  of  Loans  and (ii)  the  Outstanding  Amount  of L/C  Obligations.  The
commitment  fee shall  accrue  at all  times  from the  Closing  Date  until the
Maturity  Date and shall be due and  payable  quarterly  in  arrears on the last
Business Day of each March,  June,  September and December,  commencing with the
first such date to occur after the Closing Date,  and on the Maturity  Date. The
commitment  fee shall be  calculated  quarterly in arrears,  and if there is any
change in the  Commitment  Fee Rate with respect to  Commitment  fees during any
quarter,  the actual  daily  amount  shall be  computed  and  multiplied  by the
Commitment Fee Rate with respect to Commitment  fees  separately for each period
during such quarter that such Commitment Fee Rate was in effect.  The commitment
fee shall accrue at all times, including at any time during which one or more of
the conditions in Article IV is not met.

     (b)  Arrangement and Agency Fees. The Borrower shall pay an arrangement fee
to the Arranger for the Arranger's  own account,  and shall pay an agency fee to
the  Administrative  Agent for the  Administrative  Agent's own account,  in the
amounts and at the times specified in the letter  agreement,  dated December 17,
2001 (the "Agent and Arranger Fee Letter"), among the Borrower, the Arranger and
the Administrative Agent. Such fees shall be fully earned when paid and shall be
nonrefundable for any reason whatsoever.

     SECTION 2.11  Computation of Interest and Fees.  Computation of interest on
Base Rate Loans and  Commitment  Fees shall be calculated on the basis of a year
of 365 or 366 days,  as the case may be, and the actual  number of days elapsed.
Computation  of all other types of interest and all fees shall be  calculated on
the basis of a year of 360 days and the  actual  number of days  elapsed,  which
results in a higher yield to the payee  thereof than a method based on a year of
365 or 366  days.  Interest  shall  accrue on each Loan for the day on which the
Loan is made,  and shall not accrue on a Loan, or any portion  thereof,  for the
day on which the Loan or such  portion is paid,  provided  that any Loan that is
repaid on the same day on which it is made shall bear interest for one day.

     SECTION 2.12 Notes and Other Evidence of Debt.

     (a) The  obligation  of the Borrower to repay to each Lender the  aggregate
amount of all Loans made by such Lender (such  Lender's  "Loan"),  together with
interest  accruing  in  connection  therewith,  shall be  evidenced  by a single
promissory  note (such  Lender's  "Note")  made by the Borrower in the amount of
such  Lender's  Commitment  payable  to the order of such  Lender in the form of
Exhibit B with appropriate insertions. Each Lender may record the date, Type (if
applicable),  amount and  maturity of the  applicable  Loans and  payments  with
respect thereto in one or more schedules to its rates or on one or more accounts
or records  maintained  by such  Lender and by the  Administrative  Agent in the
ordinary  course  of  business.  The  accounts  or  records  maintained  by  the
Administrative  Agent and each Lender shall be conclusive  absent manifest error
of the amount of the Credit  Extensions  made by the Lenders to the Borrower and
the  interest  and  payments  thereon.  Any failure so to record or any error in
doing so shall not,  however,  limit or otherwise  affect the  obligation of the
Borrower  hereunder  to pay any amount  owing with  respect to the Loans and L/C
Obligations.

                                       36




     (b) In addition to the accounts and records  referred to in subsection (a),
each Lender and the  Administrative  Agent shall maintain in accordance with its
usual  practice  accounts or records  evidencing the purchases and sales by such
Lender of  participations  in Letters of  Credit.  In the event of any  conflict
between the accounts and records maintained by the Administrative  Agent and the
accounts and records of any Lender in respect of such matters,  the accounts and
records of the Administrative Agent shall control.

     SECTION 2.13 Payments Generally.

     (a) All payments to be made by the Borrower shall be made without condition
or deduction for any  counterclaim,  defense,  recoupment  or setoff.  Except as
otherwise  expressly  provided  herein,  all payments by the Borrower  hereunder
shall be made to the  Administrative  Agent,  for the account of the  respective
Lenders to which such payment is owed, at the  Administrative  Agent's Office in
Dollars and in immediately  available  funds not later than 12:00 noon,  central
time,  on the date  specified  herein.  The  Administrative  Agent will promptly
distribute to each Lender its  Percentage  Share (or other  applicable  share as
provided  herein) of such payment in like funds as received by wire  transfer to
such Lender's Lending Office. All payments received by the Administrative  Agent
after 12:00 noon,  central time, shall be deemed received on the next succeeding
Business Day and any applicable interest or fee shall continue to accrue.

     (b) Subject to the  definition  of "Interest  Period," if any payment to be
made by the Borrower shall come due on a day other than a Business Day,  payment
shall be made on the next  following  Business  Day, and such  extension of time
shall be reflected in computing interest or fees, as the case may be.

     (c) Unless the Borrower or any Lender has notified the Administrative Agent
prior to the date any payment is required to be made by it to the Administrative
Agent hereunder,  that the Borrower or such Lender, as the case may be, will not
make such payment, the Administrative Agent may assume that the Borrower or such
Lender,  as the case may be, has timely made such payment and may (but shall not
be so required to), in reliance thereon,  make available a corresponding  amount
to the Person entitled  thereto.  If and to the extent that such payment was not
in fact made to the Administrative Agent in immediately available funds, then:

          (i) if the  Borrower  failed to make such  payment,  each Lender shall
     forthwith on demand repay to the  Administrative  Agent the portion of such
     assumed  payment  that was made  available  to such  Lender in  immediately
     available  funds,  together with interest thereon (1) in respect of each of
     the first two  Business  Days from and  including  the date such amount was
     made available by the Administrative  Agent to such Lender to the date such
     amount is  repaid  to the  Administrative  Agent in  immediately  available
     funds,  at the Federal  Funds Rate from time to time in effect,  and (2) in
     respect  of each day after the first two days from and  including  the date
     such amount was made available by the  Administrative  Agent to such Lender
     to  the  date  such  amount  is  repaid  to  the  Administrative  Agent  in
     immediately  available funds, at the Base Rate from time to time in effect;
     and


                                       37


          (ii) if any Lender  failed to make such  payment,  such  Lender  shall
     forthwith on demand pay to the  Administrative  Agent the amount thereof in
     immediately  available funds, together with interest thereon for the period
     from the date such amount was made available by the Administrative Agent to
     the  Borrower to the date such amount is  recovered  by the  Administrative
     Agent (the "Compensation  Period") at a rate per annum equal to (1) for the
     first two Business Days of any Compensation  Period, the Federal Funds Rate
     from time to time in effect, and (2) for each other day of any Compensation
     Period, the interest rate applicable to the applicable  Borrowing.  If such
     Lender pays such amount to the Administrative Agent, then such amount shall
     constitute such Lender's Loan included in the applicable Borrowing. If such
     Lender does not pay such amount forthwith upon the  Administrative  Agent's
     demand therefor,  the Administrative  Agent may make a demand therefor upon
     the Borrower,  and the Borrower shall pay such amount to the Administrative
     Agent, together with interest thereon for the Compensation Period at a rate
     per  annum  equal  to the rate of  interest  applicable  to the  applicable
     Borrowing.  Nothing  herein  shall be deemed to relieve any Lender from its
     obligation  to fulfill its  Commitment or to prejudice any rights which the
     Administrative  Agent or the  Borrower  may have  against  any  Lender as a
     result of any default by such Lender hereunder.

     A notice of the  Administrative  Agent to any  Lender  with  respect to any
amount owing under this  subsection  (d) shall be  conclusive,  absent  manifest
error.

     (d) If any Lender makes available to the Administrative Agent funds for any
Loan to be made by such Lender as provided in the  foregoing  provisions of this
Article II, and the conditions to the applicable  Credit  Extension set forth in
Article IV are not satisfied or waived in accordance with the terms hereof,  the
Administrative  Agent shall  return  such funds (in like funds as received  from
such Lender) to such Lender, without interest.

     (e) The  obligations  of the  Lenders  hereunder  to make Loans and to fund
participations  in Letters of Credit are several  and not joint.  The failure of
any  Lender  to make  any Loan or to fund  any  such  participation  on any date
required  hereunder  shall not  relieve  any other  Lender of its  corresponding
obligation  to do so on such date,  and no Lender shall be  responsible  for the
failure of any other Lender to so make its Loan or purchase its participation.

     (f) Nothing  herein  shall be deemed to  obligate  any Lender to obtain the
funds  for any  Loan in any  particular  place  or  manner  or to  constitute  a
representation  by any Lender that it has  obtained or will obtain the funds for
any Loan in any particular place or manner.

     SECTION  2.14 Sharing of  Payments.  If,  other than as expressly  provided
elsewhere herein, any Lender shall obtain on account of the Loans made by it, or
the  participations  in  L/C  Obligations  held  by  it,  any  payment  (whether
voluntary,  involuntary,  through  the  exercise  of any  right of  set-off,  or
otherwise)  in  excess  of  its  ratable  share  (or  other  share  contemplated
hereunder) thereof,  such Lender shall immediately (a) notify the Administrative
Agent of such fact, and (b) purchase from the other Lenders such  participations
in the Loans made by them and/or such subparticipations in the participations in
L/C Obligations held by them, as the case may be, as shall be necessary to cause
such  purchasing  Lender to share the excess  payment in respect of such Loan or

                                       38


such  participations,  as the case may be, pro rata with each of them; provided,
however,  that  if all or any  portion  of such  excess  payment  is  thereafter
recovered  from the  purchasing  Lender,  such purchase  shall to that extent be
rescinded  and each  other  Lender  shall  repay to the  purchasing  Lender  the
purchase  price paid  therefor,  together  with an amount  equal to such  paying
Lender's  ratable share  (according to the  proportion of (i) the amount of such
paying  Lender's  required  repayment to (ii) the total amount so recovered from
the  purchasing  Lender) of any  interest or other amount paid or payable by the
purchasing  Lender in respect of the total  amount so  recovered.  The  Borrower
agrees that any Lender so purchasing a participation from another Lender may, to
the  fullest  extent  permitted  by law,  exercise  all its  rights  of  payment
(including  the right of set-off,  but subject to Section  10.9 with  respect to
such  participation  as fully as if such Lender were the direct  creditor of the
Borrower in the amount of such participation. The Administrative Agent will keep
records (which shall be conclusive and binding in the absence of manifest error)
of participations  purchased under this Section and will in each case notify the
Lenders following any such purchases or repayments. Each Lender that purchases a
participation  pursuant to this Section  shall from and after such purchase have
the  right  to  give  all  notices,  requests,  demands,  directions  and  other
communications  under  this  Agreement  with  respect  to  the  portion  of  the
Obligations  purchased to the same extent as though the  purchasing  Lender were
the original owner of the Obligations purchased.

     SECTION 2.15 Increase in Commitments.

     (a) Upon notice to the  Administrative  Agent (which shall promptly  notify
the Lenders), the Borrower may from time to time, request an increase in the
Aggregate  Commitments up the Maximum Loan Amount or invite additional  Eligible
Assignees  to become  Lenders  pursuant to an  agreement  in form and  substance
satisfactory to the Administrative  Agent, the Issuing Bank and their respective
counsel so as to increase all  commitments  to the Maximum  Loan Amount.  At the
time  of  sending  such  notice,   the  Borrower  (in   consultation   with  the
Administrative  Agent and the Issuing Bank) shall specify the time period within
which each Lender or invitee is requested to respond (which shall in no event be
less than ten  Business  Days from the date of  delivery  of such  notice to the
Lenders).  Each Lender  shall notify the  Administrative  Agent within such time
period whether or not it agrees to increase its  Commitment  and, if so, whether
by an amount equal to, greater than, or less than its  Percentage  Share of such
requested  increase.  Any Lender not responding within such time period shall be
deemed to have declined to increase its Commitment. Anything herein contained to
the contrary notwithstanding,  no Lender shall have any obligation whatsoever to
increase its Commitment hereunder.

     (b) If any Commitments  are increased in accordance with this Section,  the
Administrative Agent and the Borrower shall determine the effective date of such
increase (the  "Increase  Effective  Date").  The  Administrative  Agent and the
Borrower  shall  promptly  notify the  Lenders of the final  allocation  of such
increase  and the  Increase  Effective  Date.  As a condition  precedent to such
increase,  the Borrower shall deliver to the Administrative  Agent a certificate
of each Loan Party dated as of the Increase Effective Date (in sufficient copies
for each  Lender)  signed  by a  Responsible  Officer  of such  Loan  Party  (i)
certifying and attaching the resolutions adopted by such Loan Party approving or
consenting to such increase, and, (ii) in the case of the Borrower,  including a
Compliance  Certificate  demonstrating  pro forma  compliance  with Section 7.13
after giving effect to such increase and (iii) certifying that, before and after

                                       39


giving effect to such increase,  the representations and warranties contained in
Article V are true and correct on and as of the Increase  Effective  Date and no
Default or Event of Default  exists.  The Borrower  shall deliver new or amended
Notes  reflecting the increased  Commitment of the Lenders.  The  Administrative
Agent  shall   distribute  an  amended  Schedule  2.1  (which  shall  be  deemed
incorporated into this Agreement), to reflect any changes therein resulting from
such increase.  The Borrower shall prepay any Loans  outstanding on the Increase
Effective Date (and pay any additional amounts required pursuant to Section 3.5)
to the extent  necessary to keep the outstanding  Loans ratable with any revised
Percentage Shares arising from any nonratable  increase in the Commitments under
this Section.

     (c) This Section  shall  supersede  any  provisions  in Section 10.1 to the
contrary.


                                  ARTICLE III.
                     TAXES, YIELD PROTECTION AND ILLEGALITY

     SECTION 3.1 Taxes.

     (a) Any and all  payments  by the  Borrower  to or for the  account  of the
Administrative  Agent or any Lender under any Loan  Document  shall be made free
and clear of and  without  deduction  for any and all  present or future  taxes,
duties, levies, imposts, deductions,  assessments, fees, withholdings or similar
charges, and all liabilities with respect thereto, excluding, in the case of the
Administrative  Agent and each Lender,  taxes  imposed on or measured by its net
income,  and franchise taxes imposed on it (in lieu of net income taxes), by the
jurisdiction (or any political  subdivision thereof) under the Laws of which the
Administrative  Agent  or such  Lender,  as the  case may be,  is  organized  or
maintains  a  lending  office  (all such  non-excluded  taxes,  duties,  levies,
imposts,  deductions,  assessments,  fees,  withholdings or similar charges, and
liabilities being hereinafter referred to as "Taxes").  If the Borrower shall be
required  by any Laws to deduct any Taxes from or in respect of any sum  payable
under any Loan Document to the  Administrative  Agent or any Lender, (i) the sum
payable  shall be  increased  as  necessary  so that after  making all  required
deductions  (including  deductions  applicable to additional  sums payable under
this Section), the Administrative Agent and such Lender receives an amount equal
to the sum it would have  received had no such  deductions  been made,  (ii) the
Borrower  shall  make such  deductions,  (iii) the  Borrower  shall pay the full
amount  deducted  to the  relevant  taxation  authority  or other  authority  in
accordance with applicable  Laws, and (iv) within 30 days after the date of such
payment,  the Borrower  shall furnish to the  Administrative  Agent (which shall
forward the same to such Lender) the  original or a certified  copy of a receipt
evidencing payment thereof.

     (b) In addition,  the Borrower  agrees to pay any and all present or future
stamp,  court or  documentary  taxes and any other  excise or property  taxes or
charges or similar  levies  which  arise  from any  payment  made under any Loan
Document  or  from  the  execution,   delivery,   performance,   enforcement  or
registration  of, or otherwise  with respect to, any Loan Document  (hereinafter
referred to as "Other Taxes").

     (c) If the  Borrower  shall be required to deduct or pay any Taxes or Other
Taxes from or in  respect  of any sum  payable  under any Loan  Document  to the
Administrative  Agent  or  any  Lender,  the  Borrower  shall  also  pay  to the
Administrative  Agent (for the account of such Lender) or to such Lender, at the

                                       40


time  interest is paid,  such  additional  amount that such Lender  specifies as
necessary  to  preserve  the  after-tax  yield  (after  factoring  in all taxes,
including  taxes  imposed on or measured by net income)  such Lender  would have
received if such Taxes or Other Taxes had not been imposed.

     (d) The Borrower  agrees to  indemnify  the  Administrative  Agent and each
Lender for (i) the full amount of Taxes and Other Taxes  (including any Taxes or
Other Taxes  imposed or asserted by any  jurisdiction  on amounts  payable under
this Section)  paid by the  Administrative  Agent and such Lender,  (ii) amounts
payable  under  Section  3.1(c) and (iii) any  liability  (including  penalties,
interest and expenses) arising  therefrom or with respect thereto,  in each case
whether or not such Taxes or Other Taxes were  correctly  or legally  imposed or
asserted by the relevant Governmental  Authority.  Payment under this subsection
(d) shall be made within 30 days after the date the Lender or the Administrative
Agent makes a demand therefor.

     SECTION 3.2 Illegality.  If any Lender  determines that any Law has made it
unlawful,  or that any Governmental  Authority has asserted that it is unlawful,
for any Lender or its applicable  Lending Office to make,  maintain or fund LIBO
Rate Loans, or materially  restricts the authority of such Lender to purchase or
sell, or to take deposits of, Dollars in the applicable  offshore Dollar market,
or to  determine or charge  interest  rates based upon the LIBO Rate,  then,  on
notice thereof by such Lender to the Borrower through the Administrative  Agent,
any  obligation of such Lender to make or continue LIBO Rate Loans or to convert
Base Rate Loans to LIBO Rate Loans shall be suspended until such Lender notifies
the Administrative  Agent and the Borrower that the circumstances giving rise to
such  determination no longer exist.  Upon receipt of such notice,  the Borrower
shall, upon demand from such Lender (with a copy to the  Administrative  Agent),
prepay or, if  applicable,  convert  all LIBO Rate Loans of such  Lender to Base
Rate  Loans,  either on the last day of the  Interest  Period  thereof,  if such
Lender may  lawfully  continue to maintain  such LIBO Rate Loans to such day, or
immediately, if such Lender may not lawfully continue to maintain such LIBO Rate
Loans.  Upon any such  prepayment  or  conversion,  the Borrower  shall also pay
interest on the amount so prepaid or converted.  Each Lender agrees to designate
a  different  Lending  Office if such  designation  will avoid the need for such
notice and will not, in the good faith  judgment of such  Lender,  otherwise  be
materially disadvantageous to such Lender.

     SECTION 3.3  Inability  to Determine  Rates.  If the  Administrative  Agent
determines in  connection  with any request for a LIBO Rate Loan or a conversion
to or  continuation  thereof that (a) Dollar  deposits are not being  offered to
banks in the applicable  offshore  Dollar market for the  applicable  amount and
Interest Period of such LIBO Rate Loan, (b) adequate and reasonable means do not
exist for determining the LIBO Rate for such LIBO Rate Loan, or (c) the Adjusted
LIBO Rate for such LIBO Rate Loan does not  adequately  and fairly  reflect  the
cost to the Lenders of funding  such LIBO Rate Loan,  the  Administrative  Agent
will promptly notify the Borrower and all Lenders. Thereafter, the obligation of
the Lenders to make or maintain  LIBO Rate Loans  shall be  suspended  until the
Administrative  Agent  revokes  such notice.  Upon  receipt of such notice,  the
Borrower  may  revoke  any  pending  request  for  a  Borrowing,  conversion  or
continuation  of LIBO  Rate  Loans  or,  failing  that,  will be  deemed to have
converted  such request into a request for a Borrowing of Base Rate Loans in the
amount specified therein.

                                     41


     SECTION 3.4 Increased Cost and Reduced Return; Capital Adequacy.

     (a) If any Lender determines that as a result of the introduction of or any
change  in or in the  interpretation  of any Law,  or such  Lender's  compliance
therewith, there shall be any increase in the cost to such Lender of agreeing to
make or making,  funding or maintaining  LIBO Rate Loans or (as the case may be)
issuing or  participating  in Letters of Credit,  or a  reduction  in the amount
received or receivable  by such Lender in  connection  with any of the foregoing
(excluding  for  purposes of this  subsection  (a) any such  increased  costs or
reduction in amount resulting from (i) Taxes or Other Taxes (as to which Section
3.1 shall  govern),  (ii) changes in the basis of taxation of overall net income
or overall gross income by the United States or any foreign  jurisdiction or any
political  subdivision  of either thereof under the Laws of which such Lender is
organized or has its Lending Office, and (iii) reserve requirements utilized, as
to LIBO Rate Loans, in the  determination of the Adjusted LIBO Rate),  then from
time to time  upon  demand  of such  Lender  (with a copy of such  demand to the
Administrative  Agent),  the Borrower  shall pay to such Lender such  additional
amounts as will compensate such Lender for such increased cost or reduction.

     (b) If any Lender  determines  that the  introduction  of any Law regarding
capital  adequacy or any change  therein or in the  interpretation  thereof,  or
compliance by such Lender (or its Lending Office)  therewith,  has the effect of
reducing  the rate of return on the  capital of such  Lender or any  corporation
controlling such Lender as a consequence of such Lender's obligations  hereunder
(taking into  consideration  its policies  with respect to capital  adequacy and
such Lender's desired return on capital),  then from time to time upon demand of
such  Lender  (with a copy of such  demand  to the  Administrative  Agent),  the
Borrower  shall pay to such Lender such  additional  amounts as will  compensate
such Lender for such reduction.

     SECTION 3.5 Funding  Losses.  Upon demand of any Lender (with a copy to the
Administrative  Agent) from time to time, the Borrower shall promptly compensate
such Lender for and hold such  Lender  harmless  from any loss,  cost or expense
incurred by it as a result of:

     (a) any continuation,  conversion,  payment or prepayment of any Loan other
than a Base Rate Loan on a day other  than the last day of the  Interest  Period
for  such  Loan  (whether  voluntary,   mandatory,   automatic,   by  reason  of
acceleration, or otherwise); or

     (b) any  failure by the  Borrower  (for a reason  other than the failure of
such  Lender to make a Loan) to prepay,  borrow,  continue  or convert  any Loan
other  than a Base  Rate  Loan on the  date  or in the  amount  notified  by the
Borrower; or

     (c) any  assignment of a LIBO Rate Loan on a day other than the last day of
the Interest Period  therefor as a result of a request by the Borrower  pursuant
to Section 3.9;

including any loss of anticipated  profits and any loss or expense  arising from
the liquidation or reemployment of funds obtained by it to maintain such Loan or
from fees payable to terminate the deposits from which such funds were obtained.
The Borrower  shall also pay any customary  administrative  fees charged by such
Lender in connection with the foregoing.

                                       42


For purposes of calculating amounts payable by the Borrower to the Lenders under
this Section 3.5, each Lender shall be deemed to have funded each LIBO Rate Loan
made by it at the  LIBO  Rate  for  such  Loan by a  matching  deposit  or other
borrowing in the applicable  offshore Dollar  interbank  market for a comparable
amount and for a  comparable  period,  whether or not such LIBO Rate Loan was in
fact so funded.

     SECTION 3.6 Matters Applicable to all Requests for Compensation.

     (a) A  certificate  of the  Administrative  Agent  or any  Lender  claiming
compensation  under this Article III and setting forth the additional  amount or
amounts  to be paid to it  hereunder  shall  be  conclusive  in the  absence  of
manifest error. In determining  such amount,  the  Administrative  Agent or such
Lender may use any reasonable averaging and attribution methods.

     (b) Upon any Lender's making a claim for compensation  under Section 3.1 or
3.4, the Borrower may remove or replace such Lender in  accordance  with Section
3.9; provided that the Borrower shall have the right to replace such Lender only
if they also replace any other Lender who has made or is making a similar  claim
for compensation under Section 3.1.

     SECTION 3.7 Survival.  All of the Borrower's obligations under this Article
III shall  survive  termination  of the  Commitments  and of this  Agreement and
payment in full of all the other Obligations.

     SECTION 3.8 Foreign  Lenders.  Each Lender that is a "foreign  corporation,
partnership or trust" within the meaning of the Code (a "Foreign  Lender") shall
deliver to the Administrative  Agent, prior to receipt of any payment subject to
withholding  under the Code (or after  accepting  an  assignment  of an interest
herein),  two duly  signed  completed  copies of either  IRS Form  W-8BEN or any
successor  thereto  (relating  to such Person and  entitling  it to an exemption
from, or reduction of, withholding tax on all payments to be made to such Person
by the Borrower  pursuant to this Agreement) or IRS Form W-8ECI or any successor
thereto  (relating  to all  payments to be made to such  Person by the  Borrower
pursuant to this Agreement) or such other evidence  satisfactory to the Borrower
and the Administrative  Agent that such Person is entitled to an exemption from,
or reduction of, U.S.  withholding  tax.  Thereafter and from time to time, each
such  Person  shall  (a)  promptly  submit  to  the  Administrative  Agent  such
additional  duly  completed  and  signed  copies  of one of such  forms (or such
successor  forms as shall be adopted  from time to time by the  relevant  United
States taxing  authorities)  as may then be available  under then current United
States laws and regulations to avoid, or such evidence as is satisfactory to the
Borrower  and  the  Administrative  Agent  of any  available  exemption  from or
reduction of, United States  withholding  taxes in respect of all payments to be
made to such Person by the  Borrower  pursuant to this  Agreement,  (b) promptly
notify the  Administrative  Agent of any  change in  circumstances  which  would
modify or render invalid any claimed  exemption or reduction,  and (c) take such
steps  as shall  not be  materially  disadvantageous  to it,  in the  reasonable
judgment of such  Lender,  and as may be  reasonably  necessary  (including  the
re-designation  of its Lending  Office) to avoid any  requirement  of applicable
Laws that the Borrower make any deduction or withholding  for taxes from amounts
payable to such Person. If such Person fails to deliver the above forms or other
documentation,  then the  Administrative  Agent may  withhold  from any interest
payment to such Person an amount  equivalent to the applicable  withholding  tax
imposed  by  Sections  1441  and 1442 of the  Code,  without  reduction.  If any

                                       43


Governmental  Authority asserts that the  Administrative  Agent did not properly
withhold any tax or other amount from  payments  made in respect of such Person,
such Person shall indemnify the  Administrative  Agent  therefor,  including all
penalties and interest,  any taxes  imposed by any  jurisdiction  on the amounts
payable to the Administrative  Agent under this Section,  and costs and expenses
(including  Attorney Costs) of the  Administrative  Agent. The obligation of the
Lenders under this Section shall survive the payment of all  Obligations and the
resignation or replacement of the Administrative Agent.

     SECTION 3.9 Removal and Replacement of Lenders.

     (a) Under any  circumstances  set forth herein  providing that the Borrower
shall have the right to remove or replace a Lender as a party to this Agreement,
the Borrower may, upon notice to such Lender and the  Administrative  Agent, (i)
remove such Lender by terminating such Lender's  Commitment or (ii) replace such
Lender by causing such Lender to assign its Commitment  (without  payment of any
assignment  fee)  pursuant to Section  10.7.2(a) to one or more other Lenders or
Eligible  Assignees  procured by the Borrower;  provided,  however,  that if the
Borrower  elects to exercise  such right with respect to any Lender  pursuant to
Section 3.6(b), it shall be obligated to remove or replace,  as the case may be,
all Lenders that have made similar requests for compensation pursuant to Section
3.1 or 3.4. The Borrower shall (x) pay in full all principal, interest, fees and
other amounts owing to such Lender through the date of termination or assignment
(including any amounts payable pursuant to Section 3.5), (y) provide appropriate
assurances and indemnities  (which may include letters of credit) to the Issuing
Bank as may  reasonably  require with respect to any  continuing  obligation  to
purchase  participation  interests in any L/C Obligations then outstanding,  and
(z) release  such  Lender from its  obligations  under the Loan  Documents.  Any
Lender  being  replaced  shall  execute  and deliver an Lender  Assignment  with
respect to such Lender's  Commitment  and  outstanding  Credit  Extensions.  The
Administrative  Agent shall  distribute an amended  Schedule 2.1, which shall be
deemed incorporated into this Agreement, to reflect changes in the identities of
the Lenders and adjustments of their respective  Commitments  and/or  Percentage
Shares resulting from any such removal or replacement.

     (b) In order to make all the Lenders'  interests in any outstanding  Credit
Extensions ratable in accordance with any revised Percentage Shares after giving
effect to the removal or  replacement  of a Lender,  the  Borrower  shall pay or
prepay,  if necessary,  on the effective date thereof,  all outstanding Loans of
all Lenders,  together  with any amounts due under Section 3.5. The Borrower may
then request Loans from the Lenders in accordance with their revised  Percentage
Shares.  The Borrower may net any payments required  hereunder against any funds
being  provided  by any Lender or  Eligible  Assignee  replacing  a  terminating
Lender.  The  effect  for  purposes  of this  Agreement  shall be the same as if
separate transfers of funds had been made with respect thereto.

     (c) This  section  shall  supersede  any  provision  in Section 10.1 to the
contrary.

                                       44


                                  ARTICLE IV.

     Security  Documents,  and  together  with  stock  certificates,  membership
     interest certificates or such other certificated security as may be part of

          exist any judgment,  order,  injunction or other  restraint  issued or
          filed with respect to the making of Advances or which could reasonably
          be  expected  to impair  materially  the right or  ability  of each of
          Borrower, Comstock Acquisition Inc. and DevX to effect the Acquisition
          substantially in accordance with the terms and conditions of the Offer
          and to comply with the requirements of Section 6.17 hereof;

          pursuant  to the Offer and have not been  withdrawn,  when  aggregated
          with shares  owned by Borrower or its  Subsidiaries,  constitute  more
          than 90% of the  outstanding  shares of capital stock having  ordinary
          voting power with respect to the election of the board of directors of
          DevX   (including  all  shares  issuable  upon  the  exercise  of  the

     (c) Unless waived by the Administrative Agent, the Borrower shall have paid
all costs and expenses payable to the  Administrative  Agent pursuant to Section
10.4  to  the  extent  invoiced  prior  to or on the  Closing  Date,  plus  such
additional  amounts of costs and expenses as shall constitute the Administrative
Agent's reasonable  estimate of the costs and expenses described in Section 10.4
incurred or to be incurred by it through the closing proceedings  (provided that
such estimate shall not thereafter preclude a final settling of accounts between
the Borrower and the Administrative Agent).

     SECTION 4.2  Conditions to all Credit  Extensions.  The  obligation of each
Lender to honor any  Notice of Advance  or Letter of Credit  Application  (other
than a Notice of  Advance  requesting  only a  conversion  of Loans to the other
Type, or a  continuation  of Loans as the same Type) is subject to the following
conditions precedent:

     (a) The representations and warranties of the Borrower contained in Article
V, or which are  contained  in any  document  furnished  at any time under or in
connection  herewith,  shall be true and  correct  on and as of the date of such
Credit Extension,  except to the extent that such representations and warranties
specifically  refer to an  earlier  date,  in which  case they shall be true and
correct as of such earlier date.

     (b) No Default or Event of Default  shall exist,  or would result from such
proposed Credit Extension.

     (c) The Administrative Agent or, if applicable, the Issuing Bank shall have
received a Notice of Advance or Letter of Credit  Application in accordance with
the requirements hereof.

     (d) The  Administrative  Agent shall have  received,  in form and substance
satisfactory to it, such other assurances,  certificates,  documents or consents
related to the  foregoing as the  Administrative  Agent or the Majority  Lenders
reasonably may require.

     Each Notice of Advance or Letter of Credit Application (other than a Notice
of  Advance  requesting  only a  conversion  of  Loans  to the  other  Type or a
continuation  of Loans as the same  Type)  submitted  by the  Borrower  shall be
deemed to be a  representation  and warranty  that the  conditions  specified in
Sections 4.2 have been satisfied on and as of the date of the applicable  Credit
Extension.

                                   ARTICLE V.
                         REPRESENTATIONS AND WARRANTIES

contemplated  to be employed,  by the Borrower or any Subsidiary  infringes upon
any rights held by any other Person. No claim or litigation regarding any of the

under the Existing Credit Facility.  The Borrower and the Guarantors are engaged
as an integrated  group in the business of oil and gas  exploration  and related
fields, and any benefits to the Borrower or any Guarantor is a benefit to all of
them,  both directly or  indirectly,  inasmuch as the  successful  operation and
condition of the Borrower and the  Guarantors  is dependent  upon the  continued
successful performance of the functions of the integrated group as a whole.

than the amount that would be required to pay its probable  aggregate  liability
on its then existing debts as they become absolute and matured; (b) its or their

                                       53

prior to the  occurrence  of a Default (A) at least eighty  percent (80%) of the
present  value of the  Borrower's  and the  Guarantors'  Oil and Gas  Properties
constituting proved reserves to which value is given in the determination of the

     Administrative Agent, may reasonably request.

     (e) Production Proceeds.  Notwithstanding that, by the terms of the various
Security  Documents,  the  Loan  Parties  are  and  will  be  assigning  to  the
Administrative  Agent,  the Issuing Bank and the Lenders all of the "Production"

covered thereby,  so long as no Event of Default has occurred,  the Loan Parties
may continue to receive from the  purchasers of production  all such  Production
Proceeds,  subject,  however, to the Liens created under the Security Documents,
which Liens are hereby affirmed and ratified. Upon the occurrence of an Event of
Default, the Administrative Agent, the Issuing Bank and the Lenders may exercise

                                       61

Production  Proceeds.  In  no  case  shall  any  failure,  whether  purposed  or
inadvertent,  by the  Administrative  Agent,  the Issuing Bank or the Lenders to
collect  directly any such Production  Proceeds  constitute in any way a waiver,
remission or release of any of their rights  under the Security  Documents,  nor
shall any  release of any  Production  Proceeds by the  Administrative  Agent or
Lenders  to any Loan Party  constitute  a waiver,  remission,  or release of any
other  Production  Proceeds or of any rights of the  Administrative  Agent,  the
Issuing Bank or the Lenders to collect other Production Proceeds thereafter.

                              ADMINISTRATIVE AGENT

     SECTION 9.1 Appointment and Authorization of Administrative Agent.

     (a) Each  Lender  hereby  irrevocably  (subject to Section  9.9)  appoints,
designates and authorizes  the  Administrative  Agent to take such action on its
behalf under the  provisions of this  Agreement and each other Loan Document and
to exercise such powers and perform such duties as are expressly delegated to it
by the terms of this  Agreement or any other Loan  Document,  together with such
powers as are reasonably  incidental  thereto.  Notwithstanding any provision to
the  contrary  contained  elsewhere  herein or in any other Loan  Document,  the
Administrative Agent shall not have any duties or responsibilities, except those
expressly set forth herein, nor shall the Administrative Agent have or be deemed
to have any  fiduciary  relationship  with any  Lender  or  participant,  and no
implied  covenants,   functions,   responsibilities,   duties,   obligations  or
liabilities  shall be read into this  Agreement  or any other Loan  Document  or
otherwise  exist  against  the  Administrative   Agent.   Without  limiting  the
generality of the foregoing sentence,  the use of the term "agent" herein and in
the other Loan  Documents  with  reference  to the  Administrative  Agent is not
intended to connote any  fiduciary  or other  implied (or  express)  obligations
arising under agency doctrine of any applicable law. Instead,  such term is used
merely as a matter of market  custom,  and is intended to create or reflect only
an administrative  relationship between independent  contracting  parties.  Each
Lender hereby agrees to assert no claim against the Administrative  Agent on any
agency theory or any other theory of liability for breach of fiduciary duty, all
of which claims are hereby expressly waived by each Lender.

     (b) The Issuing Bank shall act on behalf of the Lenders with respect to any
Letters of Credit issued by it and the documents associated therewith until such
time  (and  except  for so long) as the  Administrative  Agent  may agree at the
request  of the  Majority  Lenders  to act for the  Issuing  Bank  with  respect
thereto; provided, however, that the Issuing Bank shall have all of the benefits
and immunities (i) provided to the Administrative  Agent in this Article IX with
respect  to any  acts  taken  or  omissions  suffered  by the  Issuing  Bank  in
connection  with  Letters of Credit  issued by it or proposed to be issued by it
and the  application  and  agreements  for letters of credit  pertaining  to the
Letters of Credit as fully as if the term "Administrative Agent" as used in this
Article IX included the Issuing Bank with respect to such acts or omissions, and
(ii) as additionally provided herein with respect to the Issuing Bank.

     SECTION 9.2 Delegation of Duties. The Administrative  Agent may execute any
of its duties  under this  Agreement  or any other Loan  Document  by or through
agents,  employees  or  attorneys-in-fact  and  shall be  entitled  to advice of
counsel and other  consultants or experts  concerning all matters  pertaining to
such  duties.  The  Administrative  Agent  shall  not  be  responsible  for  the

                                       72


negligence or misconduct of any agent or attorney-in-fact that it selects in the
absence of gross negligence or willful misconduct.

     SECTION 9.3 Liability of  Administrative  Agent.  No  Agent-Related  Person
shall (a) be liable for any  action  taken or omitted to be taken by any of them
under or in  connection  with this  Agreement or any other Loan  Document or the
transactions contemplated hereby (except for its own gross negligence or willful
misconduct in connection with its duties expressly set forth herein),  or (b) be
responsible  in any  manner  to any  Lender  or  participant  for  any  recital,
statement,  representation  or  warranty  made by any Loan Party or any  officer
thereof,  contained herein or in any other Loan Document, or in any certificate,
report,  statement or other document referred to or provided for in, or received
by the  Administrative  Agent under or in connection with, this Agreement or any
other Loan Document, or the validity, effectiveness, genuineness, enforceability
or sufficiency of this Agreement or any other Loan Document,  or for any failure
of any  Loan  Party or any  other  party to any Loan  Document  to  perform  its
obligations hereunder or thereunder.  No Agent-Related Person shall be under any
obligation  to any Lender or  participant  to  ascertain or to inquire as to the
observance or performance  of any of the agreements  contained in, or conditions
of, this  Agreement or any other Loan  Document,  or to inspect the  properties,
books or records of any Loan Party or any Affiliate thereof.

     SECTION 9.4 Reliance by Administrative Agent.

     (a) The Administrative  Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing,  communication,  signature,  resolution,
representation,  notice,  consent,  certificate,  affidavit,  letter,  telegram,
facsimile,   telex  or  telephone  message,   statement  or  other  document  or
conversation  believed by it to be genuine and correct and to have been  signed,
sent or made by the proper Person or Persons,  and upon advice and statements of
legal counsel (including counsel to any Loan Party), independent accountants and
other experts selected by the  Administrative  Agent. The  Administrative  Agent
shall be fully  justified  in failing or refusing  to take any action  under any
Loan Document  unless it shall first receive such advice or  concurrence  of the
Majority Lenders as it deems appropriate and, if it so requests,  it shall first
be indemnified to its  satisfaction by the Lenders against any and all liability
and expense  which may be incurred  by it by reason of taking or  continuing  to
take any such  action.  The  Administrative  Agent  shall in all  cases be fully
protected in acting,  or in refraining from acting,  under this Agreement or any
other Loan  Document  in  accordance  with a request or consent of the  Majority
Lenders or all the  Lenders,  if required  hereunder,  and such  request and any
action  taken or failure to act pursuant  thereto  shall be binding upon all the
Lenders and participants. Where this Agreement expressly permits or prohibits an
action unless the Majority Lenders otherwise determine, the Administrative Agent
shall, and in all other instances,  the Administrative  Agent may, but shall not
be  required  to,  initiate  any  solicitation  for the consent or a vote of the
Lenders.

     (b) For purposes of determining compliance with the conditions specified in
Section 4.1, each Lender that has signed this Agreement  shall be deemed to have
consented  to,  approved or accepted or to be satisfied  with,  each document or
other matter either sent by the Administrative Agent to such Lender for consent,
approval,  acceptance or satisfaction, or required thereunder to be consented to
or approved by or acceptable or satisfactory to a Lender.

                                       73


     SECTION 9.5 Notice of Default. The Administrative Agent shall not be deemed
to have  knowledge  or  notice  of the  occurrence  of any  Default  or Event of
Default,  except with respect to defaults in the payment of principal,  interest
and fees required to be paid to the Administrative  Agent for the account of the
Lenders, unless the Administrative Agent shall have received written notice from
a Lender or the Borrower referring to this Agreement, describing such Default or
Event of Default and  stating  that such  notice is a "notice of  default."  The
Administrative  Agent will notify the Lenders of its receipt of any such notice.
The Administrative  Agent shall take such action with respect to such Default or
Event of Default as may be directed by the Majority  Lenders in accordance  with
Article VIII; provided,  however, that unless and until the Administrative Agent
has received any such direction,  the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such  Default or Event of Default as it shall deem  advisable  or in the best
interest of the Lenders.

     SECTION 9.6 Credit  Decision;  Disclosure of Information by  Administrative
Agent.  Each  Lender  acknowledges  that no  Agent-Related  Person  has made any
representation  or warranty to it, and that no act by the  Administrative  Agent
hereinafter taken,  including any consent to and acceptance of any assignment or
review of the  affairs  of any Loan  Party or any  Affiliate  thereof,  shall be
deemed to constitute any representation or warranty by any Agent-Related  Person
to any Lender as to any matter,  including  whether  Agent-Related  Persons have
disclosed  material  information in their possession.  Each Lender represents to
the  Administrative  Agent that it has,  independently and without reliance upon
any  Agent-Related  Person and based on such documents and information as it has
deemed  appropriate,  made  its own  appraisal  of and  investigation  into  the
business,  prospects,  operations,  property,  financial and other condition and
creditworthiness of the Loan Parties and their respective Subsidiaries,  and all
applicable  bank  or  other   regulatory  Laws  relating  to  the   transactions
contemplated  hereby, and made its own decision to enter into this Agreement and
to extend credit to the Borrower hereunder.  Each Lender also represents that it
will, independently and without reliance upon any Agent-Related Person and based
on such  documents and  information  as it shall deem  appropriate  at the time,
continue to make its own credit analysis,  appraisals and decisions in taking or
not taking action under this Agreement and the other Loan Documents, and to make
such  investigations  as it deems necessary to inform itself as to the business,
prospects,   operations,   property,   financial   and   other   condition   and
creditworthiness of the Borrower and the other Loan Parties. Except for notices,
reports and other documents expressly required to be furnished to the Lenders by
the Administrative  Agent herein,  the  Administrative  Agent shall not have any
duty  or  responsibility  to  provide  any  Lender  with  any  credit  or  other
information concerning the business, prospects,  operations, property, financial
and other  condition  or  creditworthiness  of any of the Loan Parties or any of
their  respective   Affiliates  which  may  come  into  the  possession  of  any
Agent-Related Person.

     SECTION 9.7  Indemnification  of Administrative  Agent.  Whether or not the
transactions  contemplated  hereby are consummated,  the Lenders shall indemnify
upon demand each  Agent-Related  Person (to the extent not  reimbursed  by or on
behalf of any Loan Party and without  limiting the  obligation of any Loan Party
to do so),  pro rata,  and hold  harmless  each  Agent-Related  Person  from and
against any and all Indemnified  Liabilities incurred by it; provided,  however,
that no Lender  shall be liable for the payment to any  Agent-Related  Person of

                                       74


any portion of such Indemnified  Liabilities  resulting from such Person's gross
negligence or willful  misconduct;  provided,  however,  that no action taken in
accordance  with the  directions  of the  Majority  Lenders  shall be  deemed to
constitute gross negligence or willful  misconduct for purposes of this Section.
Without   limitation  of  the  foregoing,   each  Lender  shall   reimburse  the
Administrative  Agent  upon  demand  for  its  ratable  share  of any  costs  or
out-of-pocket expenses (including Attorney Costs) 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, any other Loan Document, or any document
contemplated  by or  referred to herein,  to the extent that the  Administrative
Agent is not reimbursed  for such expenses by or on behalf of the Borrower.  The
undertaking in this Section shall survive  termination of the  Commitments,  the
payment of all  Obligations  hereunder and the resignation or replacement of the
Administrative Agent.

     SECTION 9.8  Administrative  Agent in its Individual  Capacity.  TD and its
Affiliates may make loans to, issue letters of credit for the account of, accept
deposits from,  acquire equity  interests in and generally engage in any kind of
banking, trust, financial advisory,  underwriting or other business with each of
the Loan  Parties  and  their  respective  Affiliates  as though TD were not the
Administrative  Agent or the Issuing  Bank  hereunder  and without  notice to or
consent  of  the  Lenders.  The  Lenders  acknowledge  that,  pursuant  to  such
activities,  TD or its  Affiliates  may receive  information  regarding any Loan
Party  or  its  Affiliates  (including   information  that  may  be  subject  to
confidentiality  obligations in favor of such Loan Party or such  Affiliate) and
acknowledge  that the  Administrative  Agent  shall be  under no  obligation  to
provide such  information to them.  With respect to its Loans, TD shall have the
same rights and powers under this Agreement as any other Lender and may exercise
such  rights  and powers as though it were not the  Administrative  Agent or the
Issuing Bank, and the terms "Lender" and "Lenders"  include TD in its individual
capacity.

     SECTION 9.9 Successor  Administrative  Agent. The Administrative  Agent may
resign as  Administrative  Agent  upon 30 days'  notice to the  Lenders.  If the
Administrative  Agent resigns under this Agreement,  the Majority  Lenders shall
appoint from among the Lenders a successor administrative agent for the Lenders.
If no successor administrative agent is appointed prior to the effective date of
the  resignation  of the  Administrative  Agent,  the  Administrative  Agent may
appoint,  after consulting with the Lenders,  a successor  administrative  agent
from among the Lenders.  Upon the  acceptance  of its  appointment  as successor
administrative  agent  hereunder,  such  successor  administrative  agent  shall
succeed to all the  rights,  powers and  duties of the  retiring  Administrative
Agent  and  the  term   "Administrative   Agent"   shall  mean  such   successor
administrative agent and the retiring Administrative Agent's appointment, powers
and duties as  Administrative  Agent  shall be  terminated.  After any  retiring
Administrative  Agent's  resignation  hereunder  as  Administrative  Agent,  the
provisions  of this  Article IX and  Sections  10.4 and 10.5 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. If no successor  administrative agent
has accepted  appointment as  Administrative  Agent by the date which is 30 days
following a retiring Administrative Agent's notice of resignation,  the retiring
Administrative Agent's resignation shall nevertheless thereupon become effective

                                       75


and the  Lenders  shall  perform all of the duties of the  Administrative  Agent
hereunder  until such time, if any, as the Majority  Lenders appoint a successor
agent as provided for above.

     SECTION 9.10 Other Agents; Lead Managers. None of the Lenders identified on
the facing page or signature  pages of this Agreement as a "syndication  agent,"
"documentation agent," "co-agent" or "lead manager" shall have any right, power,
obligation,  liability,  responsibility  or duty under this Agreement other than
those applicable to all Lenders as such. Without limiting the foregoing, none of
the  Lenders  so  identified  shall  have or be  deemed  to have  any  fiduciary
relationship with any Lender.  Each Lender  acknowledges that it has not relied,
and will not rely, on any of the Lenders so identified in deciding to enter into
this Agreement or in taking or not taking action hereunder.

                                   ARTICLE X.
                                  MISCELLANEOUS

     SECTION 10.1  Amendments,  Etc. No amendment or waiver of any  provision of
this  Agreement or any other Loan  Document,  and no consent to any departure by
the Borrower or any other Loan Party  therefrom,  shall be  effective  unless in
writing  signed by the Majority  Lenders and the Borrower and  acknowledged  and
agreed by each other Loan Party, and acknowledged by the  Administrative  Agent,
and each such waiver or consent shall be effective only in the specific instance
and for the specific purpose for which given;  provided,  however,  that no such
amendment,  waiver or consent shall, unless in writing and signed by each of the
Lenders  directly  affected  thereby and by the Borrower,  and  acknowledged and
agreed by each other Loan Party and acknowledged by the Administrative Agent, do
any of the following:

     (a) extend or  increase  the  Commitment  of any Lender (or  reinstate  any
Commitment terminated pursuant to Section 8.2);

     (b)  postpone any date fixed by this  Agreement or any other Loan  Document
for any payment or mandatory  prepayment of principal,  interest,  fees or other

Document;

     (c) reduce the principal of, or the rate of interest  specified  herein on,
any Loan or L/C  Borrowing,  or any fees or other amounts  payable  hereunder or

financial  covenant used in  determining  the Base Rate Spread,  LIBOR Spread or
Commitment Fee Rate that would result in a reduction of any interest rate on any
Loan;

     (d) change the percentage of the Aggregate  Commitments or of the aggregate
unpaid principal  amount of the Loans and L/C Obligations  which is required for
the Lenders or any of them to take any action hereunder;

     (e) increase the Borrowing  Base,  or take any other action which  requires
the signing of all the Lenders pursuant to the terms of this Agreement or of any
other Loan Document,  or change the Percentage Share or Voting Percentage of any
Lender; or

                                       76


     (f) amend this Section,  or Section 2.14, or any provision herein providing
for consent or other action by all the Lenders; or

     (g) permit any termination,  amendment, modification, waiver, or release of
any Guaranty or any provision thereof; or

     (h) release any collateral under any of the Security  Documents,  or permit
any  termination,  amendment,  modification,  waiver or release of any  Security
Document or any provision thereof;

and, provided further, that (i) no amendment, waiver or consent shall, unless in
writing and signed by the Issuing  Bank in addition to the  Majority  Lenders or
all the Lenders,  as the case may be, affect the rights or duties of the Issuing
Bank under this  Agreement or any Letter of Credit  Application  relating to any
Letter of Credit  issued or to be  issued by it;  (ii) no  amendment,  waiver or
consent  shall,  unless in  writing  and signed by the  Administrative  Agent in
addition to the Majority Lenders or all the Lenders,  as the case may be, affect
the rights or duties of the  Administrative  Agent under this  Agreement  or any
other Loan Document; and (iii) the Agent and Arranger Fee Letter may be amended,
or rights or privileges  thereunder  waived,  in a writing  executed only by the
parties thereto.

     SECTION 10.2 Notices and Other Communications; Facsimile Copies.

     (a) General.  Unless otherwise  expressly  provided herein, all notices and
other  communications  provided for hereunder shall be in writing  (including by
facsimile  transmission)  and  mailed,  faxed  or  delivered,  to  the  address,
facsimile  number or (subject to subsection (c) below)  electronic  mail address
specified for notices on Schedule  10.2;  or, in the case of the  Borrower,  the
Administrative  Agent,  or the Issuing  Bank,  to such other address as shall be
designated  by such party in a notice to the other  parties,  and in the case of
any other party, to such other address as shall be designated by such party in a
notice to the Borrower,  the Administrative Agent and the Issuing Bank. All such
notices  and other  communications  shall be deemed to be given or made upon the
earlier to occur of (i) actual receipt by the intended recipient and (ii) (A) if
delivered by hand or by courier, when signed for by the intended recipient;  (B)
if delivered by mail,  four Business  Days after  deposit in the mails,  postage
prepaid; (C) if delivered by facsimile, when sent and receipt has been confirmed
by telephone; and (D) if delivered by electronic mail (which form of delivery is
subject to the provisions of subsection (c) below),  when  delivered;  provided,
however,  that notices and other  communications to the Administrative Agent and
the Issuing Bank  pursuant to Article II shall not be effective  until  actually
received  by such  Person.  Any notice or other  communication  permitted  to be
given,  made or  confirmed  by  telephone  hereunder  shall  be  given,  made or
confirmed by means of a telephone  call to the intended  recipient at the number
specified  on Schedule  10.2,  it being  understood  and agreed that a voicemail
message  shall  in  no  event  be  effective  as  a  notice,   communication  or
confirmation hereunder.

     (b) Effectiveness of Facsimile Documents and Signatures. Loan Documents may
be  transmitted  and/or  signed  by  facsimile.  The  effectiveness  of any such
documents and signatures  shall,  subject to applicable Law, have the same force
and  effect  as  manually-signed  originals  and  shall be  binding  on all Loan
Parties,  the Administrative Agent and the Lenders. The Administrative Agent may

                                       77


also  require  that  any  such  documents  and  signatures  be  confirmed  by  a
manually-signed original thereof; provided, however, that the failure to request
or deliver the same shall not limit the effectiveness of any facsimile  document
or signature.

     (c)  Limited Use of  Electronic  Mail.  Electronic  mail and  internet  and
intranet websites may be used only to distribute routine communications, such as
financial statements and other information, and to distribute Loan Documents for
execution by the parties thereto, and may not be used for any other purpose.

     (d) Reliance by Administrative  Agent and Lenders. The Administrative Agent
and the Lenders  shall be  entitled to rely and act upon any notices  (including
telephonic Notice of Advances) purportedly given by or on behalf of the Borrower
even if (i)  such  notices  were not made in a  manner  specified  herein,  were
incomplete  or were  not  preceded  or  followed  by any  other  form of  notice
specified  herein,  or (ii) the terms  thereof,  as understood by the recipient,
varied  from  any  confirmation  thereof.  The  Borrower  shall  indemnify  each
Agent-Related  Person and each  Lender  from all  losses,  costs,  expenses  and
liabilities   resulting  from  the  reliance  by  such  Person  on  each  notice
purportedly given by or on behalf of the Borrower. All telephonic notices to and
other  communications  with the  Administrative  Agent  may be  recorded  by the
Administrative  Agent,  and each of the parties  hereto hereby  consents to such
recording.

     SECTION 10.3 No Waiver;  Cumulative  Remedies.  No failure by any Lender or
the  Administrative  Agent to  exercise,  and no delay  by any  such  Person  in
exercising,  any right,  remedy, power or privilege hereunder shall operate as a
waiver thereof;  nor shall any single or partial exercise of any right,  remedy,
power or privilege  hereunder  preclude any other or further exercise thereof or
the  exercise  of any other  right,  remedy,  power or  privilege.  The  rights,
remedies,  powers and privileges  herein or therein  provided are cumulative and
not exclusive of any rights, remedies, powers and privileges provided by law.

     SECTION 10.4 Attorney Costs, Expenses and Taxes. The Borrower agrees (a) to
pay or reimburse the Administrative Agent for all costs and expenses incurred in
connection with the development,  preparation, negotiation and execution of this
Agreement and the other Loan  Documents and any  amendment,  waiver,  consent or
other  modification  of the  provisions  hereof and thereof  (whether or not the
transactions   contemplated   hereby  or  thereby  are  consummated),   and  the
consummation  and  administration  of the transactions  contemplated  hereby and
thereby,  including  all  Attorney  Costs,  and  (b)  to pay  or  reimburse  the
Administrative  Agent and each  Lender for all costs and  expenses  incurred  in
connection with the enforcement,  attempted enforcement,  or preservation of any
rights or remedies under this  Agreement or the other Loan Documents  (including
all such costs and expenses  incurred during any "workout" or  restructuring  in
respect  of the  Obligations  and  during any legal  proceeding,  including  any
proceeding  under any Debtor  Relief Law),  including  all Attorney  Costs.  The
foregoing costs and expenses shall include all search, filing, recording,  title
insurance and appraisal  charges and fees and taxes related  thereto,  and other
out-of-pocket  expenses  incurred  by the  Administrative  Agent and the cost of
independent  public  accountants  and  other  outside  experts  retained  by the
Administrative Agent or any Lender. The agreements in this Section shall survive
the termination of the Commitments and repayment of all the other Obligations.

                                       78


     SECTION  10.5   Indemnification  by  the  Borrower.   Whether  or  not  the
transactions  contemplated  hereby  are  consummated,  the  Borrower  agrees  to
indemnify, defend, save and hold harmless each Agent-Related Person, each Lender
and their respective Affiliates, directors, officers, employees, counsel, agents
and attorneys-in-fact (collectively the "Indemnitees") from and against: (a) any
and all claims,  demands,  actions or causes of action that are asserted against
any Indemnitee by any Person (other than the Administrative Agent or any Lender)
relating  directly or indirectly to a claim,  demand,  action or cause of action
that such Person asserts or may assert against any Loan Party,  any Affiliate of
any Loan Party or any of their respective officers or directors; (b) any and all
claims, demands,  actions or causes of action that may at any time (including at
any time following  repayment of the  Obligations and the resignation or removal
of the  Administrative  Agent or the  replacement  of any Lender) be asserted or
imposed  against  any  Indemnitee,  arising  out of or  relating  to,  the  Loan
Documents,  any  predecessor  loan  documents,  the  Commitments,   the  use  or
contemplated use of the proceeds of any Credit Extension, or the relationship of
any Loan Party, the Administrative Agent and the Lenders under this Agreement or
any other Loan Document;  (c) any administrative or investigative  proceeding by
any Governmental  Authority arising out of or related to a claim, demand, action
or cause of action described in subsection (a) or (b) above; and (d) any and all
liabilities (including liabilities under indemnities), losses, costs or expenses
(including  Attorney Costs) that any Indemnitee suffers or incurs as a result of
the  assertion  of  any  foregoing  claim,  demand,  action,  cause  of  action,
litigation or  proceeding,  or as a result of the  preparation of any defense in
connection with any foregoing claim, demand, action, cause of action, litigation
or proceeding,  in all cases, whether or not arising out of the negligence of an
Indemnitee,  and whether or not an Indemnitee is a party to such claim,  demand,
action,   cause  of  action,   litigation  or  proceeding  (all  the  foregoing,
collectively, the "Indemnified Liabilities");  provided that no Indemnitee shall
be entitled to indemnification  for any claim caused by its own gross negligence
or willful misconduct or for any loss asserted against it by another Indemnitee.
The agreements in this Section shall survive the  termination of the Commitments
and repayment of all the other Obligations.

     SECTION 10.6  Payments Set Aside.  To the extent that the Borrower  makes a
payment to the Administrative  Agent or any Lender, or the Administrative  Agent
or any Lender  exercises its right of set-off,  and such payment or the proceeds
of such set-off or any part thereof is subsequently invalidated,  declared to be
fraudulent or  preferential,  set aside or required  (including  pursuant to any
settlement  entered  into by the  Administrative  Agent  or such  Lender  in its
discretion)  to be  repaid  to a  trustee,  receiver  or  any  other  party,  in
connection  with any proceeding  under any Debtor Relief Law or otherwise,  then
(a) to the extent of such recovery,  the  obligation or part thereof  originally
intended to be satisfied shall be revived and continued in full force and effect
as if such payment had not been made or such set-off had not  occurred,  and (b)
each Lender severally agrees to pay to the Administrative  Agent upon demand its
applicable share of any amount so recovered from or repaid by the Administrative
Agent,  plus  interest  thereon  from the date of such  demand  to the date such
payment is made at a rate per annum  equal to (i) with  respect to the first two
Business Days following such demand, the Federal Funds Rate from time to time in
effect, and (2) with respect to each day thereafter,  the Base Rate from time to
time in effect.

     SECTION 10.7 Successors and Assigns; Assignments; Participations.

     10.7.1  Successors and Assigns.  The provisions of this Agreement  shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns permitted hereby, except that the Borrower may not assign
or otherwise  transfer any of its rights or  obligations  hereunder  without the
prior written  consent of each Lender (and any attempted  assignment or transfer
by the Borrower  without such consent  shall be null and void).  Nothing in this
Agreement,  expressed  or implied,  shall be construed to confer upon any Person
(other  than  the  parties  hereto,  their  respective  successors  and  assigns
permitted  hereby  and,  to  the  extent  expressly   contemplated  hereby,  the
Indemnitees) any legal or equitable right, remedy or claim under or by reason of
this Agreement.

10.7.2   Assignments.

     (a) Any  Lender  may  assign  to one or more  Eligible  Assignees  all or a
portion of its rights and obligations  under this Agreement  (including all or a
portion of its Commitment and the Loans (including in all instances for purposes
of this subsection (a),  participations in L/C Obligations) at the time owing to
it);  provided  that (i)  except  in the  case of an  assignment  of the  entire
remaining amount of the assigning Lender's  Commitment and the Loans at the time
owing to it or in the case of an  assignment  to a Lender or an  Affiliate  of a
Lender,  the aggregate amount of the Commitment (which for this purpose includes
Loans outstanding  thereunder,  including as noted above,  participations in L/C
Obligations)  subject  to each such  assignment,  determined  as of the date the
Lender   Assignment  with  respect  to  such  assignment  is  delivered  to  the
Administrative  Agent,  shall not be less  than  $5,000,000  unless  each of the
Administrative  Agent and, so long as no Default has occurred and is  continuing
and so long as in the case of Toronto  Dominion  (Texas) Inc., such Lender shall
have been  reduced to its  "target  hold"  level as  described  in the Agent and
Arranger Fee Letter,  the Borrower  otherwise consents (each such consent not to
be unreasonably withheld or delayed), (ii) each partial assignment shall be made
as an assignment of a  proportionate  part of all the assigning  Lender's rights
and obligations under this Agreement with respect to the Loans or the Commitment
assigned,  except  that this  clause  (ii) shall not  prohibit  any Lender  from
assigning  all or a  portion  of  its  rights  and  obligations  among  separate
Borrowings on a non-pro rata basis,  (iii) the parties to each assignment  shall
execute and deliver to the Administrative  Agent a Lender  Assignment,  together
with a processing  and  recordation  fee of $3,500.  Subject to  acceptance  and
recording thereof by the Administrative Agent pursuant to subsection (c) of this
Section,  from and after the effective date specified in each Lender Assignment,
the Eligible  Assignee  thereunder shall be a party hereto and, to the extent of
the interest assigned by such Lender Assignment, have the rights and obligations
of a Lender under this Agreement,  and the assigning Lender thereunder shall, to
the extent of the interest assigned by such Lender Assignment,  be released from
its obligations  under this Agreement (and, in the case of an Lender  Assignment
covering  all of the  assigning  Lender's  rights  and  obligations  under  this
Agreement, such Lender shall cease to be a party hereto but shall continue to be
entitled to the benefits of Sections  3.7,  10.4 and 10.5).  Upon  request,  the
Borrower (at its expense) shall execute and deliver new or replacement  Notes to
the assigning  Lender and the assignee  Lender.  Any assignment or transfer by a

                                       80


Lender of rights or  obligations  under this Agreement that does not comply with
this  subsection  shall be treated for  purposes of this  Agreement as a sale by
such Lender of a participation in such rights and obligations in accordance with
subsection (d) of this Section.

     (b) The Administrative Agent, acting solely for this purpose as an agent of
the Borrower, shall maintain at the Administrative Agent's Office a copy of each
Lender  Assignment  delivered  to it and a register for the  recordation  of the
names and addresses of the Lenders, and the Commitments of, and principal amount
of the Loans and L/C  Obligations  owing to, each  Lender  pursuant to the terms
hereof from time to time (the "Register").  The entries in the Register shall be
conclusive, and the Borrower, the Administrative Agent and the Lenders may treat
each Person whose name is recorded in the Register  pursuant to the terms hereof
as a Lender hereunder for all purposes of this Agreement, notwithstanding notice
to the contrary.  The Register shall be available for inspection by the Borrower
and any Lender,  at any  reasonable  time and from time to time upon  reasonable
prior notice.

     10.7.3 Participations.

     (a) Any Lender may,  without the consent of, or notice to, the  Borrower or
the  Administrative  Agent,  sell  participations  to one or more banks or other
entities (a  "Participant")  in all or a portion of such Lender's  rights and/or
obligations  under this Agreement  (including all or a portion of its Commitment
and/or the Loans  (including such Lender's  participations  in L/C  Obligations)
owing to it);  provided that (i) such Lender's  obligations under this Agreement
shall remain unchanged,  (ii) such Lender 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 Lenders shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement.  Any agreement or instrument pursuant to which
a Lender sells such a participation  shall provide that such Lender shall retain
the  sole  right  to  enforce  this  Agreement  and to  approve  any  amendment,
modification  or waiver of any provision of this  Agreement;  provided that such
agreement  or  instrument  may provide  that such  Lender will not,  without the
consent of the Participant, agree to any amendment, waiver or other modification
that would (i) postpone any date upon which any payment of money is scheduled to
be paid to such Participant, (ii) reduce the principal,  interest, fees or other
amounts  payable to such  Participant,  or (iii) release any Guarantor  from the
Guaranty.  Subject to subsection (e) of this Section,  the Borrower  agrees that
each Participant  shall be entitled to the benefits of Sections 3.1, 3.4 and 3.5
to the same  extent as if it were a Lender  and had  acquired  its  interest  by
assignment  pursuant to subsection (b) of this Section.  To the extent permitted
by law, each  Participant also shall be entitled to the benefits of Section 10.9
as though it were a Lender,  provided such  Participant  agrees to be subject to
Section 2.14 as though it were a Lender.

     (b) A  Participant  shall not be entitled  to receive  any greater  payment
under Section 3.1 or 3.4 than the applicable  Lender would have been entitled to
receive with respect to the participation  sold to such Participant,  unless the
sale of the  participation to such Participant is made with the Borrower's prior
written  consent.  A  Participant  that  would be a Foreign  Lender if it were a
Lender  shall not be entitled to the benefits of Section 3.1 unless the Borrower
is notified of the  participation  sold to such Participant and such Participant
agrees, for the benefit of the Borrower, to comply with Section 3.8 as though it
were a Lender.

                                       81


     10.7.4  Pledge of Lender's  Interest.  Any Lender may at any time pledge or
assign a  security  interest  in all or any  portion  of its  rights  under this
Agreement  (including  under its Notes,  if any) to secure  obligations  of such
Lender,  including any pledge or assignment to secure  obligations  to a Federal
Reserve Bank;  provided that no such pledge or assignment shall release a Lender
from any of its obligations hereunder or substitute any such pledgee or assignee
for such Lender as a party hereto.

     10.7.5  Consent  to  Assignment.  If  the  consent  of the  Borrower  to an
assignment or to an Eligible Assignee is required hereunder (including a consent
to an assignment which does not meet the minimum assignment  threshold specified
in clause  (i) of the  proviso to the first  sentence  of  Section  10.7.2,  the
Borrower  shall be deemed to have given its consent five Business Days after the
date notice  thereof has been  delivered by the  assigning  Lender  (through the
Administrative  Agent) unless such consent is expressly  refused by the Borrower
prior to such fifth Business Day.

     10.7.6  Definitions  for Section 10.7. As used herein,  the following terms
have the following meanings:

          "Eligible   Assignee"  means  (a)  a  Lender;   (b)  an
          Affiliate of a Lender;  and (c) any other Person (other
          than a natural Person)  approved by the  Administrative
          Agent,  the Issuing Bank,  and, after Toronto  Dominion
          (Texas),  Inc. shall have assigned a sufficient  amount
          of its Commitment (as set forth in Schedule 2.1) to one
          or more Persons (who shall  become  Lenders)  such that
          the Toronto  Dominion  (Texas),  Inc.'s  Commitment has
          been  reduced to an amount not  exceeding  the  "target
          hold"  level set forth in the  Agent and  Arranger  Fee
          Letter,  and provided  that no Default has occurred and
          is continuing,  the Borrower (each such approval not to
          be unreasonably withheld or delayed).

          "Fund" means any Person  (other than a natural  Person)
          that is (or will be)  engaged  in  making,  purchasing,
          holding or otherwise  investing in commercial loans and
          similar  extensions of credit in the ordinary course of
          its business.

               10.7.7 Assignment by TD. Notwithstanding anything to the contrary
          contained  herein, if at any time TD assigns all of its Commitment and
          Loans pursuant to subsection  (b) above,  TD may, upon 30 days' notice
          to the Borrower and the Lenders,  resign as Issuing Bank. In the event
          of any  such  resignation  as  Issuing  Bank,  the  Borrower  shall be
          entitled to appoint  from among the Lenders a successor  Issuing  Bank
          hereunder;  provided,  however,  that no  failure by the  Borrower  to
          appoint  any such  successor  shall  affect the  resignation  of TD as
          Issuing  Bank. TD shall retain all the rights and  obligations  of the
          Issuing  Bank   hereunder  with  respect  to  all  Letters  of  Credit
          outstanding  as of the effective  date of its  resignation  as Issuing
          Bank and all L/C Obligations with respect thereto (including the right
          to require the Lenders to make Base Rate Loans or fund  participations
          in Unreimbursed Amounts pursuant to Section 2.3.3).

                                       82


     SECTION 10.8 Confidentiality.  (a) Each of the Administrative Agent and the
Lenders agrees to maintain the  confidentiality  of the  Information (as defined
below),  except that Information may be disclosed (a) to its and its Affiliates'
directors,  officers, employees and agents, including accountants, legal counsel
and other advisors (it being understood that the Persons to whom such disclosure
is made will be  informed of the  confidential  nature of such  Information  and
instructed to keep such Information  confidential);  (b) to the extent requested
by any regulatory  authority;  (c) to the extent  required by applicable laws or
regulations or by any subpoena or similar legal process;  (d) to any other party
to this Agreement; (e) in connection with the exercise of any remedies hereunder
or any suit, action or proceeding  relating to this Agreement or the enforcement
of  rights  hereunder;   (f)  subject  to  an  agreement  containing  provisions
substantially the same as those of this Section, to (i) any Eligible Assignee of
or Participant  in, or any prospective  Eligible  Assignee of or Participant in,
any of its  rights or  obligations  under this  Agreement  or (ii) any direct or
indirect   contractual   counterparty  or  prospective   counterparty  (or  such
contractual counterparty's or prospective  counterparty's  professional advisor)
to any credit  derivative  transaction  relating to obligations of the Borrower;
(g) with the consent of the  Borrower;  (h) to the extent such  Information  (i)
becomes publicly available other than as a result of a breach of this Section or
(ii)  becomes  available  to  the  Administrative  Agent  or  any  Lender  on  a
nonconfidential  basis  from a source  other  than the  Borrower;  or (i) to the
National   Association   of  Insurance   Commissioners   or  any  other  similar
organization or any nationally  recognized rating agency that requires access to
information  about  a  Lender's  or  its  Affiliates'  investment  portfolio  in
connection  with ratings  issued with respect to such Lender or its  Affiliates.
For the purposes of this Section,  "Information" means all information  received
from the Borrower relating to the Borrower or its business,  other than any such
information  that is  available to the  Administrative  Agent or any Lender on a
nonconfidential basis prior to disclosure by the Borrower; provided that, in the
case of  information  received  from the Borrower  after the date  hereof,  such
information  is  clearly  identified  in  writing  at the  time of  delivery  as
confidential. Any Person required to maintain the confidentiality of Information
as  provided in this  Section  shall be  considered  to have  complied  with its
obligation  to do so if such  Person has  exercised  the same  degree of care to
maintain the  confidentiality of such Information as such Person would accord to
its own confidential information.

     SECTION 10.9 Set-off. In addition to any rights and remedies of the Lenders
provided by law, upon the occurrence and during the  continuance of any Event of
Default,  each Lender is authorized  at any time and from time to time,  without
prior  notice to the  Borrower  or any other Loan Party,  any such notice  being
waived by the  Borrower  (on its own behalf and on behalf of each Loan Party) 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 by,
and other indebtedness at any time owing by, such Lender to or for the credit or
the account of the respective Loan Parties against any and all Obligations owing
to such Lender,  now or hereafter  existing,  irrespective of whether or not the
Administrative  Agent or such Lender shall have made demand under this Agreement
or any other Loan  Document and although such  Obligations  may be contingent or
unmatured.   Each  Lender  agrees  promptly  to  notify  the  Borrower  and  the
Administrative Agent after any such set-off and application made by such Lender;
provided,  however,  that the failure to give such  notice  shall not affect the
validity of such set-off and application.

                                       83


     SECTION 10.10 Interest Rate Limitation.  It is the intention of the parties
hereto to conform strictly to applicable usury laws and,  anything herein to the
contrary notwithstanding, the obligations of the Borrower to each Lender and the
Issuing  Bank under this  Agreement  shall be  subject  to the  limitation  that
payments of interest  shall not be required to the extent that  receipt  thereof
would be contrary to provisions of law  applicable to such Lender or the Issuing
Bank limiting rates of interest which may be charged or collected by such Lender
or the Issuing Bank. Accordingly,  if the transactions contemplated hereby would
be usurious  under  applicable  law (including the Federal and state laws of the
United  States  of  America,  or of any  other  jurisdiction  whose  laws may be
mandatorily  applicable)  with respect to a Lender or the Issuing Bank then,  in
that event,  notwithstanding  anything to the contrary in this Agreement,  it is
agreed as follows:  (i) the  provisions  of this Section  10.10 shall govern and
control;  (ii) the aggregate of all  consideration  which  constitutes  interest
under  applicable  law that is contracted  for,  charged or received  under this
Agreement,  or under any of the  other  aforesaid  agreements  or  otherwise  in
connection with this Agreement by such Lender or the Issuing Bank shall under no
circumstances  exceed the maximum  amount of interest  allowed by applicable law
(such maximum  lawful  interest rate, if any, with respect to such Lender or the
Issuing Bank herein called the "Highest  Lawful Rate"),  and any excess shall be
credited  to the  Borrower  by such  Lender or the  Issuing  Bank  (or,  if such
consideration shall have been paid in full, such excess promptly refunded to the
Borrower);  (iii) all sums  paid,  or agreed  to be paid,  to the  Lender or the
Issuing Bank for the use,  forbearance and detention of the  indebtedness of the
Borrower to such  Lender or the  Issuing  Bank  hereunder  shall,  to the extent
permitted  by  applicable  law, be  amortized,  prorated,  allocated  and spread
throughout the full term of such indebtedness  until payment in full so that the
actual rate of interest is uniform throughout the full term thereof; and (iv) if
at any time the interest provided pursuant to Article II together with any other
fees payable  pursuant to this Agreement and deemed  interest  under  applicable
law,  exceeds that amount  which would have accrued at the Highest  Lawful Rate,
the amount of interest and any such fees to accrue to such Lender or the Issuing
Bank pursuant to this Agreement  shall be limited,  notwithstanding  anything to
the  contrary in this  Agreement  to that amount which would have accrued at the
Highest  Lawful Rate, but any subsequent  reductions,  as applicable,  shall not
reduce the  interest to accrue to such Lender or the  Issuing  Bank  pursuant to
this Agreement  below the Highest Lawful Rate until the total amount of interest
accrued  pursuant to this  Agreement and such fees deemed to be interest  equals
the amount of interest  which  would have  accrued to such Lender or the Issuing
Bank if a varying  rate per annum  equal to the  interest  provided  pursuant to
Article II had at all times been in effect,  plus the amount of fees which would
have been  received  but for the effect of this Section  10.10.  For purposes of
Tex. Fin. Code Ann. Ch. 303, as amended,  to the extent, if any, applicable to a
Lender or the Issuing  Bank,  the Borrower  agrees that the Highest  Lawful Rate
shall be the "weekly  ceiling" as defined in said  Article,  provided  that such
Lender and the Issuing Bank may also rely, to the extent permitted by applicable
laws, on alternative  maximum rates of interest  under other laws  applicable to
such Lender or such Issuer, as the case may be, if greater.  Tex. Fin. Code Ann.
Ch. 346 (which  regulates  certain  revolving credit loan accounts and revolving
tri-party accounts) shall not apply to this Agreement or the Notes.

     SECTION 10.11  Counterparts.  This Agreement may be executed in one or more
counterparts,  each of  which  shall be  deemed  an  original,  but all of which
together shall constitute one and the same instrument.

                                       84


     SECTION   10.12   Survival   of   Representations   and   Warranties.   All
representations  and warranties made hereunder and in any other Loan Document or
other document delivered pursuant hereto or thereto or in connection herewith or
therewith  shall  survive the execution  and delivery  hereof and thereof.  Such
representations  and  warranties  have  been  or  will  be  relied  upon  by the
Administrative  Agent and each Lender,  regardless of any investigation  made by
the  Administrative  Agent or any Lender or on their behalf and  notwithstanding
that the Administrative  Agent or any Lender may have had notice or knowledge of
any Default or Event of Default at the time of any Credit  Extension,  and shall
continue  in full force and  effect as long as any Loan or any other  Obligation
shall  remain  unpaid  or  unsatisfied  or any  Letter of  Credit  shall  remain
outstanding.

     SECTION 10.13  Severability.  Any provision of this Agreement and the other
Loan  Documents  to  which  the  Borrower  is a  party  that  is  prohibited  or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability  without  invalidating the
remaining  provisions  thereof,  and any such prohibition or unenforceability in
any jurisdiction shall not invalidate or render  unenforceable such provision in
any other jurisdiction.

     SECTION 10.14 Governing Law.

     (a) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE  WITH,
THE LAW OF THE  STATE  OF NEW  YORK  APPLICABLE  TO  AGREEMENTS  MADE  AND TO BE
PERFORMED  ENTIRELY  WITHIN SUCH STATE (WITHOUT  GIVING EFFECT TO THE PRINCIPLES
THEREOF  RELATING  TO  CONFLICT  OF LAW  EXCEPT  SECTION  5-1401 OF THE NEW YORK
GENERAL OBLIGATIONS LAW); PROVIDED THAT THE ADMINISTRATIVE AGENT AND EACH LENDER
SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

     (b) ANY LEGAL ACTION OR  PROCEEDING  WITH RESPECT TO THIS  AGREEMENT OR ANY
OTHER  LOAN  DOCUMENT  MAY BE  BROUGHT  IN THE  COURTS  OF THE STATE OF NEW YORK
SITTING IN MANHATTAN OR OF THE UNITED  STATES FOR THE SOUTHERN  DISTRICT OF SUCH
STATE,  AND BY  EXECUTION  AND DELIVERY OF THIS  AGREEMENT,  THE  BORROWER,  THE
ADMINISTRATIVE AGENT AND EACH LENDER CONSENTS,  FOR ITSELF AND IN RESPECT OF ITS
PROPERTY, TO THE NON-EXCLUSIVE  JURISDICTION OF THOSE COURTS. THE BORROWER,  THE
ADMINISTRATIVE AGENT AND EACH LENDER IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING
ANY  OBJECTION  TO THE  LAYING  OF VENUE OR BASED ON THE  GROUNDS  OF FORUM  NON
CONVENIENS,  WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR
PROCEEDING  IN SUCH  JURISDICTION  IN  RESPECT  OF ANY  LOAN  DOCUMENT  OR OTHER
DOCUMENT RELATED THERETO. THE BORROWER, THE ADMINISTRATIVE AGENT AND EACH LENDER
WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE
MADE BY ANY OTHER MEANS PERMITTED BY THE LAW OF SUCH STATE.

     SECTION  10.15  Waiver  of  Right to  Trial  by  Jury.  EACH  PARTY TO THIS
AGREEMENT  HEREBY  EXPRESSLY  WAIVES  ANY  RIGHT TO TRIAL BY JURY OF ANY  CLAIM,

                                       85


DEMAND,  ACTION OR CAUSE OF ACTION ARISING UNDER ANY LOAN DOCUMENT OR IN ANY WAY
CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR
ANY OF THEM WITH  RESPECT  TO ANY LOAN  DOCUMENT,  OR THE  TRANSACTIONS  RELATED
THERETO,  IN EACH CASE WHETHER NOW EXISTING OR  HEREAFTER  ARISING,  AND WHETHER
FOUNDED IN  CONTRACT  OR TORT OR  OTHERWISE;  AND EACH PARTY  HEREBY  AGREES AND
CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED
BY COURT TRIAL WITHOUT A JURY,  AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN
ORIGINAL  COUNTERPART  OR A COPY OF THIS  SECTION  WITH  ANY  COURT  AS  WRITTEN
EVIDENCE OF THE CONSENT OF THE  SIGNATORIES  HERETO TO THE WAIVER OF THEIR RIGHT
TO TRIAL BY JURY.

     SECTION  10.16  Consents to Renewals,  Modifications  and Other Actions and
Events.  This  Agreement and all of the  obligations  of the Borrower  hereunder
shall  remain  in full  force  and  effect  without  regard  to and shall not be
released,  affected or impaired  by: (a) any  amendment,  assignment,  transfer,
modification  of or addition or  supplement  to the  Lenders  Obligations,  this
Agreement,  any Note or any other Loan Document; (b) any extension,  indulgence,
increase in the Lenders  Obligations  or other  action or inaction in respect of
any of the Loan Documents or otherwise with respect to the Lenders  Obligations,
or any  acceptance  of  security  for,  or  guaranties  of,  any of the  Lenders
Obligations or Loan Documents, or any surrender,  release, exchange,  impairment
or alteration of any such security or guaranties  including  without  limitation
the failing to perfect a security  interest in any such  security or  abstaining
from taking  advantage or of realizing  upon any guaranties or upon any security
interest in any such  security;  (c) any default by the Borrower  under,  or any
lack of due execution, invalidity or unenforceability of, or any irregularity or

other Person of any required performance or otherwise of any condition precedent
or  waiver  of  any  requirement  imposed  by any of  the  Loan  Documents,  any
guaranties  or  otherwise  with  respect  to the  Lenders  Obligations;  (e) any
exercise or non-exercise of any right,  remedy, power or privilege in respect of
this Agreement or any of the other Loan Documents; (f) any sale, lease, transfer
or other  disposition  of the assets of the  Borrower  or any  consolidation  or
merger of the Borrower with or into any other Person, corporation, or entity, or
any  transfer or other  disposition  by the  Borrower or any other holder of any
shares of capital stock or other  ownership  interest of the  Borrower;  (g) any
bankruptcy,  insolvency,  reorganization  or similar  proceedings  involving  or
affecting  the  Borrower;  (h) the release or discharge of the Borrower from the
performance or observance of any agreement,  covenant,  term or condition  under
any of the Obligations or contained in any of the Loan Documents by operation of
law; or (i) any other  cause  whether  similar or  dissimilar  to the  foregoing
which,  in the absence of this  provision,  would release,  affect or impair the
Obligations,  covenants,  agreements  and  duties  of  the  Borrower  hereunder,
including without limitation any act or omission by the Administrative Agent, or
the Lenders or any other  Person  which  increases  the scope of the  Borrower's
risk; and in each case  described in this paragraph  whether or not the Borrower
shall  have  notice  or  knowledge  of any of the  foregoing,  each of  which is
specifically waived by the Borrower. The Borrower warrants to the Administrative
Agent and the Lenders that it has adequate  means to obtain from the  Guarantors
on a continuing basis information  concerning the financial  condition and other

                                       86


matters  with  respect  to  the   Guarantors  and  it  is  not  relying  on  the
Administrative Agent or the Lenders to provide such information either now or in
the future.

Loan Documents,  comprises the complete and integrated  agreement of the parties
on the subject matter hereof and thereof and  supersedes  all prior  agreements,
written or oral,  on such  subject  matter.  THIS  AGREEMENT  AND THE OTHER LOAN
DOCUMENTS  REPRESENT  THE FINAL  AGREEMENT  BETWEEN  THE  PARTIES AND MAY NOT BE
CONTRADICTED  BY  EVIDENCE  OF  PRIOR,   CONTEMPORANEOUS,   OR  SUBSEQUENT  ORAL
AGREEMENTS OF THE PARTIES.  THERE ARE NO UNWRITTEN ORAL  AGREEMENTS  BETWEEN THE
PARTIES.


                                       87


     IN WITNESS  WHEREOF,  the parties  hereto have caused this  Agreement to be
duly executed as of the date first above written.
