ARTICLE 2.  CREDIT FACILITIES.

      2.1   REVOLVING LOAN FACILITY.

      (a) COMMITMENT. Each Bank severally agrees, on the terms and conditions
set forth in this Agreement and for the purposes set forth in Section 5.4, to
make Revolving Credit Advances to the Borrower as such Bank's ratable share of
Revolving Credit Borrowings requested by the Borrower from time to time on any
Business Day during the period from the date of this Agreement until the
Revolving Credit Commitment Termination Date provided that (i) the outstanding
principal amount of Revolving Credit Advances made by such Bank plus such Bank's
ratable share of the Letter of Credit Exposure shall not exceed such Bank's
Revolving Credit Commitment and (ii) before the Borrowing Base Termination
Condition occurs, the outstanding principal amount of the Revolving Credit Loan
after giving effect to any Borrowing Request pursuant to which such Bank shall
make a Revolving Credit Advance plus the Letter of Credit Exposure shall not
exceed the Borrowing Base. On the date this Agreement becomes effective under
Section 3.1, the outstanding principal amount of each Bank's Advances (as
defined in the Existing Credit Agreement) less such Bank's Term Loan Commitment
shall be automatically converted into, and be deemed to be made as, a Revolving
Credit Advance. Except as provided in the prior sentence, Revolving Credit
Borrowings must be made in an amount equal to or greater than the applicable
Minimum Borrowing Amount and be made in multiples of the Minimum Borrowing
Multiple. Within the limits expressed in this Agreement, the Borrower may from
time to time borrow, prepay, and reborrow Revolving Credit Borrowings. The
indebtedness of the Borrower to the Banks resulting from the Revolving Credit
Advances made by the Banks shall be evidenced by Revolving Credit Notes made by
the Borrower.

      (b) REDUCTION OF COMMITMENTS. The Borrower shall have the right, upon at
least 10 days' irrevocable written notice to the Agent, to terminate in whole or
reduce the unused portion of the Commitments (such reductions to be apportioned
ratably among each Bank's Commitment); PROVIDED that each partial reduction
shall be in the aggregate amount of $5,000,000 or in integral multiples of
$1,000,000 in excess thereof. Any such reduction of the Commitments shall be
irrevocable, and amounts by which the Commitments are reduced hereunder shall
not be available for Advances following such reduction. Upon reduction of the
Commitments under this paragraph, the commitment fee provided for in Section
2.4(b) shall thereafter be computed on the basis of the Commitments, as so
reduced. All Advances outstanding on the date of any reduction in the
Commitments are subject to prepayment in accordance with Section 2.1(d)(ii)
below.

      (c) METHOD OF ADVANCING. Each Revolving Credit Borrowing shall be made
pursuant to a Borrowing Request given by the Borrower to the Agent in writing or
by telecopy not later than the time required pursuant to Section 2.5(a) to
select the interest rate basis for the Revolving Credit Borrowing. Each
Borrowing Request shall be fully completed and shall specify the information
required therein, and shall be irrevocable and binding on the Borrower.

                                      -21-
<PAGE>
      (d)   PREPAYMENT.

         (i) The Borrower may prepay the outstanding principal amount of the
      Revolving Loan pursuant to written notice given by the Borrower to the
      Agent in writing or by telecopy not later than 1:00 p.m. (local time at
      the Applicable Lending Office of the Agent) (A) on the third Business Day
      before the date of the proposed prepayment, in the case of the prepayment
      of any portion of the Revolving Loan which is comprised of LIBOR Tranches,
      or (B) on the same Business Day of the proposed prepayment, in the case of
      the prepayment of any portion of the Revolving Loan comprised solely of
      Prime Rate Tranches. Each such notice shall specify the principal amount
      and the Tranches of the Revolving Loan which shall be prepaid, the date of
      the prepayment, and shall be irrevocable and binding on the Borrower.
      Prepayments of the Revolving Loan shall be made in integral multiples of
      the Minimum Borrowing Multiple. If the prepayment would cause the
      aggregate outstanding principal amount of any LIBOR Tranche comprising the
      Revolving Loan or the aggregate outstanding principal amount of all Prime
      Rate Tranches comprising the Revolving Loan, to be less than the Minimum
      Tranche Amount, the prepayment must be in an amount equal to the entire
      outstanding principal amount of such LIBOR Tranche under the Revolving
      Loan or the entire outstanding principal amount of all such Prime Rate
      Tranches under the Revolving Loan, as the case may be. Upon receipt of any
      notice of prepayment, the Agent shall give prompt notice of the intended
      prepayment to the Banks. For each such notice given by the Borrower, the
      Borrower shall prepay the Revolving Loan in the specified amount on the
      specified date as set forth in such notice. The Borrower shall have no
      right to prepay any principal amount of the Revolving Loan except as
      provided in this Section 2.1(d)(i).

        (ii) If the aggregate outstanding principal amount of the Revolving Loan
      plus the Letter of Credit Exposure ever exceeds the Commitment or, before
      the Borrowing Base Termination Condition occurs, the Borrowing Base, the
      Borrower shall, to the extent of such excess, immediately prepay to the
      Agent for the ratable benefit of the Banks the outstanding principal of
      the Revolving Loan, and, if the Revolving Loan has been repaid in full,
      make deposits into the Letter of Credit Collateral Account to provide cash
      collateral for the Letter of Credit Exposure, such that such excess is
      eliminated.

       (iii) Each prepayment of principal of any LIBOR Tranche under the
      Revolving Loan pursuant to this Section 2.1(d) shall be accompanied by
      payment of all accrued but unpaid interest on the principal amount prepaid
      and any amounts required to be paid pursuant to Section 2.6 as a result of
      such prepayment.

      (e) REPAYMENT. The Borrower shall pay to the Agent for the ratable benefit
of the Banks the aggregate outstanding principal amount of the Revolving Loan on
the Revolving Credit Maturity Date.

of this Agreement until the Revolving Credit Maturity Date provided that (i) the
Letter of Credit Exposure shall not exceed the Letter of Credit Sublimit and
(ii) the aggregate outstanding principal amount of Revolving Credit Advances
plus the Letter of Credit Exposure shall not exceed the aggregate amount of the
Commitments or, before the Borrowing Base Termination Condition occurs, the

months after its issuance date, and each Letter of Credit which is
self-extending beyond its expiration date must be cancelable upon at least 30
days notice given by the Issuing Bank to the beneficiary of such Letter of
Credit. No Letter of Credit may have an expiration date later than 12 months
after the Revolving Credit Maturity Date unless approved by the Issuing Bank,
the Agent, and the Banks. Each Letter of Credit must be in form and substance
acceptable to the Issuing Bank. The indebtedness of the Borrower to the Issuing
Bank resulting from Letters of Credit requested by the Borrower shall be
evidenced by the Letter of Credit Applications made by the Borrower.

      (b) REQUESTING LETTERS OF CREDIT. Each Letter of Credit shall be issued,
increased, or extended pursuant to a Letter of Credit Application or Letter of
Credit Application Amendment, as applicable, given by the Borrower to the
Issuing Bank in writing or by telecopy promptly confirmed in writing, such
Letter of Credit Application or Letter of Credit Application Amendment being
given not later than 10:00 a.m. (local time at the Applicable Lending Office of
the Agent) on the third Business Day before the date of the proposed issuance,
increase, or extension of the Letter of Credit. Each Letter of Credit
Application or Letter of Credit Application Amendment shall be fully completed
and shall specify the information required therein (including the proposed form
of the Letter of Credit or change thereto), and shall be irrevocable and binding
on the Borrower. The Issuing Bank shall give prompt notice of the Letter of
Credit Application or Letter of Credit Application Amendment to the Agent, and
the Agent shall promptly inform the Banks of the proposed Letter of Credit or
change thereto. Subject to the satisfaction of all applicable conditions
precedent, the Issuing Bank shall before close of business on the date requested
by the Borrower for the issuance, increase, or extension of such Letter of
Credit issue, increase, or extend such Letter of Credit to the specified
beneficiary. Upon the date of the issuance, increase, or extension of a Letter
of Credit, the Issuing Bank shall be deemed to have sold to each other Bank and
each other Bank shall be deemed to have purchased from the Issuing Bank a
ratable participation in the related Letter of Credit. The Issuing Bank shall
notify the Agent of each Letter of Credit issued, increased, or extended and the
date and amount of each Bank's participation in such Letter of Credit, and the
Agent shall in turn notify the Banks.

      (c REIMBURSEMENTS FOR LETTERS OF CREDIT. With respect to any Letter of
Credit and in accordance with the related Letter of Credit Application, the
Borrower agrees to pay to the Issuing Bank on demand of the Issuing Bank any
amount due to the Issuing Bank under such Letter of Credit Application (provided
that fees due with respect to such Letter of Credit shall be payable as
specified in Section 2.4(c)). If the Borrower does not pay upon demand of the
Issuing Bank any amount due to the Issuing Bank under any Letter of Credit
Application, in addition to any rights the

                                      -23-
<PAGE>
Issuing Bank may have under such Letter of Credit Application, the Issuing Bank
may upon written notice to the Agent request the satisfaction of such obligation
by the making of a Revolving Credit Borrowing. Upon such request, the Borrower
shall be deemed to have requested the making of a Revolving Credit Borrowing in
the amount of such obligation and the transfer of the proceeds thereof to the
Issuing Bank. Such Revolving Credit Borrowing shall be comprised of a Prime Rate
Tranche. The Agent shall promptly forward notice of such Borrowing to the
Borrower and the Banks, and each Bank shall, in accordance with the procedures
of Section 2.10, other than limitations on the size of Revolving Credit
Borrowings, and notwithstanding the failure of any conditions precedent, make
available such Bank's ratable share of such Revolving Credit Borrowing to the
Agent, and the Agent shall promptly deliver the proceeds thereof to the Issuing
Bank for application to such Bank's share of the obligations under such Letter
of Credit. The Borrower hereby unconditionally and irrevocably authorizes,
empowers, and directs the Issuing Bank to make such requests for Revolving
Borrowings on behalf of the Borrower, and the Banks to make Revolving Credit
Advances to the Agent for the benefit of the Issuing Bank in satisfaction of
such obligations. The Agent and each Bank may record and otherwise treat the
making of such Revolving Credit Borrowings as the making of a Revolving Credit
Borrowing to the Borrower under this Agreement as if requested by the Borrower.
Nothing herein is intended to release the Borrower's obligations under any
Letter of Credit Application, but only to provide an additional method of
payment therefor. The making of any Revolving Credit Borrowing under this
Section 2.2(c) shall not constitute a cure or waiver of any Default or Event of
Default caused by the Borrower's failure to comply with the provisions of this
Agreement or any Letter of Credit Application.

      (d PREPAYMENTS OF LETTERS OF CREDIT. In the event that any Letters of
Credit shall be outstanding according to their terms after the Revolving Credit
Maturity Date, the Borrower shall pay to the Agent an amount equal to the Letter
of Credit Exposure allocable to such Letters of Credit to be held in the Letter
of Credit Collateral Account and applied in accordance with paragraph (g) below.

      (e OBLIGATIONS UNCONDITIONAL. The obligations of the Borrower and each
Bank under this Agreement and the Letter of Credit Applications to reimburse the
Issuing Bank for draws under Letters of Credit and to make other payments due in
respect of Letters of Credit shall be unconditional and irrevocable, and shall
be paid strictly in accordance with the terms of this Agreement and the Letter
of Credit Applications under all circumstances, including: (i) any lack of
validity or enforceability of any Letter of Credit Document; (ii) any amendment,
waiver, or consent to departure from any Letter of Credit Document; (iii) the
existence of any claim, set-off, defense, or other right which the Borrower or
any Bank may have at any time against any beneficiary or transferee of any
Letter of Credit (or any Persons for whom any such beneficiary or any such
transferee may be acting), the Issuing Bank, or any other person or entity,
whether in connection with the transactions contemplated in this Agreement or
any unrelated transaction; (iv) any statement or any 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 (v) payment by the Issuing Bank under any Letter of Credit
against presentation of a draft or certificate which does not comply with the
terms of such Letter of Credit; provided, however, that nothing contained in
this paragraph (d) shall be deemed to constitute a waiver of any remedies of the
Borrower or any Bank in connection with the Letters of Credit or the Borrower's
or such Bank's rights under paragraph (e) below.

                                      -24-

      (f LIABILITY OF ISSUING BANK. The Issuing Bank shall not be liable or
responsible for: (i) the use which may be made of any Letter of Credit or any
acts or omissions of any beneficiary or transferee in connection therewith; (ii)
the validity, sufficiency, or genuineness of documents related to Letters of
Credit, or of any endorsement thereon, even if such documents should prove to be
in any or all respects invalid, insufficient, fraudulent, or forged; (iii)
payment by the Issuing Bank against presentation of documents which do not
strictly comply with the terms of a Letter of Credit, including failure of any
documents to bear any reference or adequate reference to the relevant Letter of
Credit; or (iv) any other circumstances whatsoever in making or failing to make
payment under any Letter of Credit (INCLUDING THE ISSUING BANK'S OWN
NEGLIGENCE); except that the Issuing Bank shall be liable to the Borrower or any
Bank to the extent of any direct, as opposed to consequential, damages suffered
by the Borrower or such Bank which the Borrower or such Bank proves were caused
by (A) the Issuing Bank's gross negligence or willful misconduct in determining
whether documents presented under a Letter of Credit comply with the terms of
such Letter of Credit, (B) the Issuing Bank's willful failure to make or delay
in making lawful payment under any Letter of Credit after the presentation to it
of documentation strictly complying with the terms and conditions of such Letter
of Credit, or (C) the Issuing Bank's negligence in the handling of money.

      (g    LETTER OF CREDIT COLLATERAL ACCOUNT.

        (ii So long as no Event of Default exists, (A) the Agent shall apply the
      funds held in the Letter of Credit Collateral Account only to the
      reimbursement of any reimbursement obligations and other obligations under
      Letter of Credit Documents, (B) the Agent shall release to the Borrower at
      the Borrower's written request funds held in the Letter of Credit
      Collateral Account in an amount up to but not exceeding the excess, if any
      (immediately prior to the release of any such funds), of the total amount
      of funds held in the Letter of Credit Collateral Account over the Letter
      of Credit Exposure, and (C) the Agent shall, at the unanimous written
      direction of the Banks in their sole discretion, at any time release to
      the Borrower any funds held in the Letter of Credit Collateral Account.
      During the existence of any Default or Event of Default, the Agent may
      apply any funds held in the Letter of Credit Collateral Account to any
      Credit Obligations in any order determined by the Agent, regardless of any
      Letter of Credit Exposure which may remain outstanding.

       (iii Funds held in the Letter of Credit Collateral Account shall be
      invested in

                                      -25-
<PAGE>
      money market funds of the Agent or in another investment if mutually
      agreed upon by the Borrower and the Agent, but the Agent shall have no
      other obligation to make any other investment of the funds therein. The
      Agent shall exercise reasonable care in the custody and preservation of
      any funds held in the Letter of Credit Collateral Account and shall be
      deemed to have exercised such care if such funds are accorded treatment
      substantially equivalent to that which the Agent accords its own property,
      it being understood that the Agent shall not have any responsibility for
      taking any necessary steps to preserve rights against any parties with
      respect to any such funds.

      (h EXISTING LETTERS OF CREDIT. Upon the date of the execution of this
Agreement, the Issuing Bank shall be deemed to have sold to each other Bank and
each other Bank shall be deemed to have purchased from the Issuing Bank a
ratable participation in each Existing Letter of Credit, which shall thereafter
be treated as a Letters of Credit under this Agreement for all purposes. The
Issuing Bank shall arrange with the Agent and the Banks to prorate and ratably
distribute to the Banks the fees previously paid to the Issuing Bank with
respect to such Existing Letters of Credit.

      2.3   TERM LOAN FACILITY.

      (a COMMITMENT FOR TERM LOAN. On the date this Agreement becomes effective
under Section 3.1, an amount of each Bank's Advances (as defined in the Existing
Credit Agreement) equal to such Bank's Term Loan Commitment shall be
automatically converted into, and be deemed to be made as, a Term Loan Advance.
The Term Loan Commitment is not revolving and therefore Term Loan Advances that
have been made and then prepaid may not be readvanced. The indebtedness of the
Borrower to the Banks resulting from the Term Loan Advances made by the Banks
shall be evidenced by Term Loan Notes made by the Borrower.

      (b METHOD OF ADVANCING. The Term Loan Borrowing shall be made pursuant to
the Borrowing Request given by the Borrower to the Agent in writing or by
telecopy not later than the time required pursuant to Section 2.5(a) to select
the interest rate basis for the Term Loan Borrowing. The Borrowing Request shall
be fully completed and shall specify the information required therein, and shall
be irrevocable and binding on the Borrower.

      (c    PREPAYMENT.

         (i The Borrower may prepay the outstanding principal amount of Term
      Loan pursuant to written notice given by the Borrower to the Agent in
      writing or by telecopy not later than (A) 1:00 p.m. (local time at the
      Applicable Lending Office of the Agent) on the third Business Day before
      the date of the proposed prepayment, in the case of the prepayment of any
      portion of Term Loan which is comprised of LIBOR Tranches, or (B) 11:00
      a.m. (local time at the Applicable Lending Office of the Agent) on the
      same Business Day of the proposed prepayment, in the case of the
      prepayment of any portion of Term Loan comprised solely of the Prime Rate
      Tranche. Each such notice shall specify the principal amount and Tranche
      or Tranches of Term Loan which shall be prepaid, the date of the
      prepayment, and shall be irrevocable and binding on the Borrower. Partial
      prepayments of the Term Loan shall be made in a minimum amount equal to or
      greater than the Minimum Borrowing Amount, shall not cause any Tranche to
      be less than the Minimum

                                      -26-
<PAGE>
      Tranche Amount, and shall not cause the outstanding principal amount of
      Term Loan to be less than the Minimum Borrowing Amount. Upon receipt of
      any notice of prepayment, the Agent shall give prompt notice of the
      intended prepayment to the Banks. For each such notice given by the
      Borrower, the Borrower shall prepay Term Loan in the specified amount on
      the specified date as set forth in such notice. The Borrower shall have no
      right to prepay any principal amount of Term Loan except as provided in
      this Section 2.3(c)(i).

        (ii The Borrower shall prepay the outstanding principal amount of the
      Term Loan (A) within 60 days after it has received notice from the Agent
      that the outstanding principal amount of the Term Loan exceeds the Term
      Loan Borrowing Base, by at least the amount of such excess; (B) on the
      Business Day after the closing of sale of any assets (including stock of a
      Subsidiary of the Borrower) with gross sale proceeds attributable to any
      single sale (whether in one or more related transactions) of more than
      $5,000,000, by an amount equal to the Net Cash Proceeds from such sale;
      (C) (i) when an Event of Default has occurred and is continuing, on the
      first Business Day after the occurrence of such Event of Default or the
      Borrower's receipt thereof, 100% of the Net Cash Proceeds the Borrower or
      any of its Subsidiaries receives from a casualty insurance policy or
      condemnation award, to the extent that the same equals or exceeds
      $1,000,000, while an Event of Default has occurred and is continuing or
      received before such occurrence, but has not been reinvested in the
      replacement assets as of the date of such occurrence and (ii) on the 185th
      day after receipt of thereof, 100% of the Net Cash Proceeds the Borrower
      or any of its Subsidiaries receives from an insurance policy or
      condemnation award that are not reinvested in replacement assets of
      comparable value and utility (or committed to be so reinvested) within six
      months after receipt of such insurance proceeds or condemnation award; and
      (D) on the first Business day after the receipt thereof, 50% of the Net
      Cash Proceeds from any Equity Issuance.

       (iii Each prepayment of principal on a LIBOR Tranche pursuant to this
      Section 2.3(c) shall be accompanied by payment of any amounts required to
      be paid pursuant to Section 2.6 as a result of such prepayment.

        (iv Each prepayment of principal pursuant this Section 2.3(c) shall be
      applied to the required principal payments on Term Loan in the inverse
      order of maturity; PROVIDED that any prepayment required to be made within
      60 days after receipt of the appraisals required pursuant to Section
      5.2(d) hereof shall instead be applied to reduce, on a pro rata basis,
      each remaining principal payment on the Term Loan.

      (d REPAYMENT. The Borrower shall repay to the Agent for the ratable
benefit of the Banks the outstanding principal amount of the Term Loan in equal
monthly principal installments of $595,238.10 (as such amount may be ratably
reduced by the proviso set forth above in Section 2.3(c)(iv), which shall be due
any payable on the last day of each month beginning with July 31, 2000 and
until, but not including, the Term Loan Maturity Date. The Borrower shall repay
to the Agent for the ratable benefit of the Banks the outstanding principal
amount of Term Loan on the Term Loan Maturity Date.

      2.4   FEES.

      (a UPFRONT FEES. Subject to Section 2.5(d), the Borrower shall pay to the
Agent for the ratable benefit of each Bank an upfront fee for such Bank equal to
the product of (i) the Commitments of such Bank multiplied by (ii) 0.25%.

      (b COMMITMENT FEES. The Borrower shall pay to the Agent for the ratable
benefit of the Banks a commitment fee in an amount equal to the product of (i)
the Applicable Margin for Commitment Fees multiplied by (ii) the average daily
amount by which (x) the aggregate amount of the Commitments exceeds (y) the
outstanding principal amount of the Revolving Loan plus the Letter of Credit
Exposure. The commitment fee shall be due and payable quarterly in arrears on
the last day of each calendar quarter commencing June 30, 2000 and on the
Revolving Credit Maturity Date.

      (c FEES FOR LETTERS OF CREDIT. For each Letter of Credit issued by the
Issuing Bank, the Borrower shall pay to the Agent for the ratable benefit of the
Banks a letter of credit fee equal to the Applicable Margin for Letter of Credit
fees per annum in effect from time to time on the original face amount of such
Letter of Credit for the stated term of such Letter of Credit. In addition, for
each Letter of Credit issued by the Issuing Bank, the Borrower shall pay to the
Agent for the benefit of the Issuing Bank a fronting fee of 0.125% per annum on
the original face amount of such Letter of Credit for the stated term of such
Letter of Credit, with a minimum fee of $500. The Borrower shall pay such letter
of credit fees for each Letter of Credit quarterly in arrears within ten days
after when billed therefor by the Issuing Bank. The Borrower shall have no right
to any refund of letter of credit fees previously paid by the Borrower,
including any refund claimed because the Borrower cancels any Letter of Credit
prior to its expiration date.

      (d AGENT FEE LETTER. The Borrower shall pay to the parties specified
therein the fees and other amounts payable under Agent Fee Letter and the letter
dated March 13, 2000 between the Agent and the Borrower.

      2.5   INTEREST.

      (a  ELECTION OF INTEREST RATE BASIS. The Borrower may select the interest
rate basis for each Borrowing in accordance with the terms of this Section
2.5(a):

         (i Under the Borrowing Request provided to the Agent in connection with
      the making of each Borrowing under the Revolving Loan, the Borrower shall
      select the amount and the Type of the Tranches, and for each LIBOR Tranche
      selected, any permitted Interest Period for each such LIBOR Tranche, which
      will comprise such Borrowing, provided that (A) at no time shall there be
      more than eight separate LIBOR Tranches outstanding under the Revolving
      Loan and (B) each Tranche must be in a principal amount equal to or
      greater than the Minimum Tranche Amount and be made in multiples of the
      Minimum Tranche Multiple. Such interest rate elections must be provided to
      the Agent in writing or by telecopy not later than 10:00 a.m. (local time
      at the Applicable Lending Office of the Agent) (A) on the third Business
      Day before the date of any proposed Borrowing comprised of a LIBOR
      Tranche, or (B) on the same day of any proposed Borrowing

                                      -28-
<PAGE>
      comprised solely of a Prime Rate Tranche. The Agent shall promptly forward
      copies of such interest rate elections to the Banks. In the case of any
      Borrowing comprised of a LIBOR Tranche, upon determination by the Agent,
      the Agent shall promptly notify the Borrower and the Banks of the
      applicable interest rate for such Tranche.

        (ii With respect to any Tranche under the Revolving Loan, the Borrower
      may continue or convert any portion of any LIBOR Tranche or Prime Rate
      Tranche to form new LIBOR Tranches or Prime Rate Tranches under the
      Revolving Loan in accordance with this paragraph. Each such continuation
      or conversion shall be made pursuant to a Continuation/Conversion Request
      given by the Borrower to the Agent in writing or by telecopy not later
      than 12:00 noon (local time at the Applicable Lending Office of the Agent)
      on the third Business Day before the date of the proposed continuation or
      conversion. Each Continuation/Conversion Request shall be fully completed
      and shall specify the information required therein, and shall be
      irrevocable and binding on the Borrower. The Agent shall promptly forward
      notice of the continuation or conversion to the Banks. In the case of any
      continuation or conversion into LIBOR Tranches, upon determination by the
      Agent, the Agent shall notify the Borrower and the Banks of the applicable
      interest rate. Continuations and conversions of Tranches shall be made in
      integral multiples of the Minimum Tranche Multiple. No continuation or
      conversion shall be permitted if such continuation or conversion would
      cause the aggregate outstanding principal amount of any LIBOR Tranche
      which would remain outstanding or the aggregate outstanding principal
      amount of all Prime Rate Tranches which would remain outstanding to be
      less than the Minimum Tranche Amount. At no time shall there be more than
      eight separate LIBOR Tranches outstanding under the Revolving Loan. Any
      conversion of an existing LIBOR Tranche is subject to Section 2.5. Subject
      to the satisfaction of all applicable conditions precedent, the Agent and
      the Banks shall before close of business on the date requested by the
      Borrower for the continuation or conversion, make such continuation or
      conversion.

       (iii At the end of the Interest Period for any LIBOR Tranche, if the
      Borrower has not continued or converted such LIBOR Tranche into new
      Tranches as provided for in paragraph (ii) above, the Borrower shall be
      deemed to have continued such LIBOR Tranche as a Prime Rate Tranche. Each
      Prime Rate Tranche shall continue as a Prime Rate Tranche unless the
      Borrower converts such Prime Rate Tranche as provided for in paragraph
      (ii) above.

      (b LIBOR TRANCHES. Each LIBOR Tranche shall bear interest during its
Interest Period at a per annum interest rate equal to the lesser of (i) the
Highest Lawful Rate or (ii) the sum of the LIBOR for such Tranche plus the
Applicable Margin for LIBOR Tranches in effect from time to time. The Borrower
shall pay to the Agent for the ratable benefit of the Banks all accrued but
unpaid interest on each LIBOR Tranche on the last day of the applicable Interest
Period for such LIBOR Tranche (and with respect to LIBOR Tranches with Interest
Periods of greater than three months, on the date which is three months after
the first date of the Interest Period for such LIBOR Tranche), when required
upon prepayment as specified elsewhere in this Agreement, on any date when any
portion of any LIBOR Tranche is prepaid (but only to the extent of the portion
of any such LIBOR Tranche is prepaid), and on the Revolving Credit Maturity Date
and the Term Loan Maturity Date.

                                      -29-
<PAGE>
      (c PRIME RATE TRANCHES. Each Prime Rate Tranche shall bear interest at a
per annum interest rate equal to the lesser of (i) the Highest Lawful Rate or
(ii) the Adjusted Prime Rate in effect from time to time plus the Applicable
Margin for Prime Rate Tranches in effect from time to time. The Borrower shall
pay to the Agent for the ratable benefit of the Banks all accrued but unpaid
interest on outstanding Prime Rate Tranches on the last day of each calendar
quarter, when required upon prepayment as specified elsewhere in this Agreement,
on any date all Prime Rate Tranches are prepaid in full, and on the Revolving
Credit Maturity Date and the Term Loan Maturity Date.

      (d    USURY PROTECTION.

         (i Nothing contained in this Agreement or the Notes shall require the
      Borrower to pay interest at a rate exceeding the Highest Lawful Rate. Each
      provision in the Credit Documents and any other agreement executed in
      connection herewith is expressly limited so that in no event whatsoever
      shall the amount paid thereunder, or otherwise paid, by the Borrower for
      the use, forbearance or detention of the money to be loaned under this
      Agreement, exceed that amount of money which would cause the effective
      rate of interest thereon to exceed the Highest Lawful Rate, and all
      amounts payable under the Credit Documents or any other agreement executed
      in connection herewith, or otherwise payable in connection therewith,
      shall be subject to reduction so that such amounts paid or payable for the
      use, forbearance or detention of money to be loaned under this Agreement
      shall not exceed that amount of money which would cause the effective rate
      of interest thereon to exceed the Highest Lawful Rate.

        (ii If the amount of interest payable for the account of any Bank on any
      interest payment date in respect of the immediately preceding interest
      computation period, computed pursuant to this Section 2.5, would exceed
      the maximum amount permitted by applicable law to be charged by such Bank,
      the amount of interest payable for its account on such interest payment
      date shall be automatically reduced to such maximum permissible amount.

       (iii If the amount of interest payable for the account of any Bank in
      respect of any interest computation period is reduced pursuant to clause
      (d)(ii) above and the amount of interest payable for its account in
      respect of any subsequent interest computation period, computed pursuant
      to this Section 2.5, would be less than the maximum amount permitted by
      applicable law to be charged by such Bank, then the amount of interest
      payable for its account in respect of such subsequent interest computation
      period shall be automatically increased to the maximum amount permitted by
      applicable law to be charged by such Bank; PROVIDED that at no time shall
      the aggregate amount by which interest paid for the account of any Bank
      has been increased pursuant to this clause (d)(iii) exceed the aggregate
      amount by which interest paid for its account has theretofore been reduced
      pursuant to clause (d)(ii) of this Section.

        (iv In the event that maturity of the loans made hereunder is
      accelerated for any reason, or in the event of any required or permitted
      prepayment of such loans, then such consideration that constitutes
      interest payable for the account of any Bank shall never include

                                      -30-
<PAGE>
      more than the maximum amount permitted by applicable law to be charged by
      such Bank and excess interest, if any, payable for the account of such
      Bank pursuant to its Note, this Agreement or otherwise shall be canceled
      automatically as of the date of such acceleration or prepayment and, if
      theretofore paid, shall be credited on the loans made hereunder by such
      Bank (or, to the extent in excess of such loans, refunded by such Bank to
      the Borrower).

         (v It is further agreed that, without limitation of the foregoing, all
      calculations of the rate of interest contracted for, charged or received
      for the account of any Bank under the Note held by it, under this
      Agreement, under any other agreement executed in connection herewith or
      otherwise in connection with the loans made hereunder by or the Commitment
      of such Bank for the purpose of determining whether such rate exceeds the
      Highest Lawful Rate, shall be made, to the extent permitted by applicable
      usury law (now or hereafter enacted), by amortizing, prorating and
      spreading in equal parts during the period of the full stated terms of the
      loans evidenced by such Note all interest at any time contracted for,
      charged or received by such Bank in connection therewith.

      2.6 BREAKAGE COSTS. If (i) any payment of principal on or any conversion
of any LIBOR Tranche is made on any date other than the last day of the Interest
Period for such LIBOR Tranche, whether as a result of any voluntary or mandatory
prepayment, any acceleration of maturity, or any other cause, (ii) any payment
of principal on any LIBOR Tranche is not made when due, or (iii) any LIBOR
Tranche is not borrowed, converted, or prepaid in accordance with the respective
notice thereof provided by the Borrower to the Agent, whether as a result of any
failure to meet any applicable conditions precedent for borrowing, conversion,
or prepayment, the permitted cancellation of any request for borrowing,
conversion, or prepayment, the failure of the Borrower to provide the respective
notice of borrowing, conversion, or prepayment, or any other cause not specified
above which is created by the Borrower, then the Borrower shall pay to each Bank
upon demand any amounts required to compensate such Bank for any losses, costs,
or expenses, including lost profits and administrative expenses, which are
reasonably allocable to such action, including losses, costs, and expenses
related to the liquidation or redeployment of funds acquired or designated by
such Bank to fund or maintain such Bank's ratable share of such LIBOR Tranche or
related to the reacquisition or redesignation of funds by such Bank to fund or
maintain such Bank's ratable share of such LIBOR Tranche following any
liquidation or redeployment of such funds caused by such action. A certificate
as to the amount of such loss, cost, or expense detailing the calculation
thereof and certifying that such Bank customarily charges such amounts to its
other customers in similar circumstances submitted by such Bank to the Borrower
shall be conclusive and binding for all purposes, absent manifest error.

      2.7   INCREASED COSTS.

      (a COST OF FUNDS. If due to either (i) any introduction of, change in, or
change in the interpretation of any law or regulation after the date of this
Agreement or (ii) compliance with any guideline or request from any central bank
or other governmental authority having appropriate jurisdiction (whether or not
having the force of law) given after the date of this Agreement, there shall be
any increase in the costs of any Bank allocable to (x) committing to make any
Advance or obtaining funds for the making, funding, or maintaining of such
Bank's ratable share of any LIBOR

                                      -31-
<PAGE>
Tranche in the relevant interbank market or (y) committing to make Letters of
Credit or issuing, funding, or maintaining Letters of Credit (including any
increase in any applicable reserve requirement specified by the Federal Reserve
Board, including those for emergency, marginal, supplemental, or other
reserves), then the Borrower shall pay to such Bank upon demand any amounts
required to compensate such Bank for such increased costs, such amounts being
due and payable upon demand by such Bank. A certificate as to the cause and
amount of such increased cost detailing the calculation of such cost and
certifying that such Bank customarily charges such amounts to its other
customers in similar circumstances submitted by such Bank to the Borrower shall
be conclusive and binding for all purposes, absent manifest error.
Notwithstanding the foregoing, the Borrower shall not be obligated to pay any
such amounts that accrued more than 90 days prior to delivery of such
certificate to the Borrower.

      (b CAPITAL ADEQUACY. If, due to either (i) any introduction of, change in,
or change in the interpretation of any law or regulation after the date of this
Agreement or (ii) compliance with any guideline or request from any central bank
or other governmental authority having appropriate jurisdiction (whether or not
having the force of law) given after the date of this Agreement, there shall be
any increase in the capital requirements of any Bank or its parent or holding
company allocable to (x) committing to make Advances or making, funding, or
maintaining Advances or (y) committing to make Letters of Credit or issuing,
funding, or maintaining Letters of Credit, as such capital requirements are
allocated by such Bank, then the Borrower shall pay to such Bank upon demand any
amounts required to compensate such Bank or its parent or holding company for
such increase in costs (including an amount equal to any reduction in the rate
of return on assets or equity of such Bank or its parent or holding company),
such amounts being due and payable upon demand by such Bank. A certificate as to
the cause and amounts detailing the calculation of such amounts and certifying
that such Bank customarily charges such amounts to its other customers in
similar circumstances submitted by such Bank to the Borrower shall be conclusive
and binding for all purposes, absent manifest error. Notwithstanding the
foregoing, the Borrower shall not be obligated to pay any such amounts that
accrued more than 90 days prior to delivery of such certificate to the Borrower.

      2.8 ILLEGALITY. Notwithstanding any other provision in this Agreement, if
it becomes unlawful for any Bank to obtain deposits or other funds for making or
funding such Bank's ratable share of any LIBOR Tranche in the relevant interbank
market, such Bank shall so notify the Borrower and the Agent and such Bank's
commitment to create LIBOR Tranches shall be suspended until such condition has
passed, all LIBOR Tranches applicable to such Bank shall be converted to Prime
Rate Tranches as of the end of each applicable Interest Period or earlier if
necessary, and all subsequent requests for LIBOR Tranches shall be deemed to be
requests for Prime Rate Tranches with respect to such Bank.

                                      -32-
<PAGE>
      2.9 MARKET FAILURE. Notwithstanding any other provision in this Agreement,
if the Agent determines that: (a) quotations of interest rates for the relevant
deposits referred to in the definition of "LIBOR" are not being provided in the
relevant amounts, or maturities for purposes of determining the rate of interest
referred to in the definition of "LIBOR" or (b) the relevant rates of interest
referred to in the definition of "LIBOR" which are used as the basis to
determine the rate of interest for LIBOR Tranches are not likely to adequately
cover the cost to any Bank of making or maintaining such Bank's ratable share of
any LIBOR Tranche, then if the Agent so notifies the Borrower, the commitment of
the Banks to make any Borrowing comprised of LIBOR Tranches shall be suspended
until such condition has passed, all LIBOR Tranches shall be converted to Prime
Rate Tranches as of the end of each applicable Interest Period or earlier if
necessary, and all subsequent requests for LIBOR Tranches shall be deemed to be
requests for Prime Rate Tranches.

      2.10  ADVANCING AND PAYMENTS GENERALLY; COMPUTATIONS.

      (a ADVANCING PROCEDURES. Time is of the essence in this Agreement and the
Credit Documents. All advances hereunder shall be made in Dollars. Upon receipt
of any Borrowing Request by the Agent, the Agent shall promptly forward notice
of the Borrowing to the Banks. Subject to the satisfaction of the applicable
conditions precedent, each Bank shall, before 1:00 p.m. (local time at the
Applicable Lending Office of the Agent) on the date of the requested Borrowing,
make available from its Applicable Lending Office to the Agent at the Agent's
Applicable Lending Office, in immediately available funds, such Bank's ratable
share of such Borrowing. Subject to the satisfaction of all applicable
conditions precedent, after receipt by the Agent of such funds, the Agent shall,
by 4:00 p.m. (local time at the Applicable Lending Office of the Agent) on the
date requested for such Borrowing, make such Borrowing available to the Borrower
in immediately available funds at any account of Borrower which is designated in
writing by the Borrower to the Agent.

      (b AGENT RELIANCE ON BANKS IN ADVANCING. Unless the Agent shall have
received notice from a Bank before the date of any Borrowing that such Bank
shall not make available to the Agent such Bank's ratable share of such
Borrowing, the Agent may assume that such Bank has made its ratable share of
such Borrowing available to the Agent on the date of such Borrowing in
accordance with this Agreement and the Agent may, in reliance upon such
assumption, make available to the Borrower on such date a corresponding amount.
If and to the extent that such Bank shall not have so made its ratable share of
such Borrowing available to the Agent, such Bank agrees that it shall pay
interest on such amount for each day from the date such amount is made available
to the Borrower by the Agent until the date such amount is paid to the Agent by
such Bank at the Federal Funds Rate in effect from time to time, provided that
with respect to such Bank if such amount is not paid by such Bank by the end of
the second day after the Agent makes such amount available to the Borrower, the
interest rates specified above shall be increased by a per annum amount equal to
2.00% on the third day and shall remain at such increased rate thereafter.
Interest on such amount shall be due and payable by such Bank upon demand by the
Agent. If such Bank shall pay to the Agent such amount and interest as provided
above, such amount so paid shall constitute such Bank's Advance as part of such
Borrowing for all purposes of this Agreement even though not made on the same
day as the other Advances comprising such Borrowing. In the event that such Bank
has not repaid such amount by the end of the fifth day after such amount was
made available to the Borrower, the Borrower agrees to repay to the Agent on
demand such amount, together with interest on such amount for each day from the
date such amount was made available to the Borrower until

                                      -33-
<PAGE>
the date such amount is repaid to the Agent at the interest rate charged to the
Borrower for such Borrowing under the terms of this Agreement. The failure of
any Bank to make available its ratable share of any Borrowing shall not relieve
any other Bank of its obligation, if any, to make available its ratable share of
such Borrowing. No Bank shall be responsible for the failure of any other Bank
to honor such other Bank's obligations hereunder, including any failure to make
available any funds as part of any Borrowing.

      (c PAYMENT PROCEDURES. Time is of the essence in this Agreement and the
Credit Documents. All payments hereunder shall be made in Dollars. The Borrower
shall make each payment under this Agreement and under the Notes not later than
1:00 p.m. (local time at the Applicable Lending Office of the Agent) on the day
when due to the Agent at the Agent's Applicable Lending Office in immediately
available funds. All payments by the Borrower hereunder shall be made without
any offset, abatement, withholding, deduction, counterclaim, or reduction. Upon
receipt of payment from the Borrower of any principal, interest, or fees due to
the Banks, the Agent shall promptly after receipt thereof distribute to the
Banks their ratable share of such payments for the account of their respective
Applicable Lending Offices. If and to the extent that the Agent shall not have
so distributed to any Bank its ratable share of such payments, the Agent agrees
that it shall pay interest on such amount for each day after the day when such
amount is made available to the Agent by the Borrower until the date such amount
is paid to such Bank by the Agent at the Federal Funds Rate in effect from time
to time, provided that if such amount is not paid by the Agent by the end of the
third day after the Borrower makes such amount available to the Agent, the
interest rates specified above shall be increased by a per annum amount equal to
2.00% on the fourth day and shall remain at such increased rate thereafter.
Interest on such amount shall be due and payable by the Agent upon demand by
such Bank. Upon receipt of other amounts due solely to the Agent, the Issuing
Bank, or a specific Bank, the Agent shall distribute such amounts to the
appropriate party to be applied in accordance with the terms of this Agreement.

      (d AGENT RELIANCE. Unless the Agent shall have received written notice
from the Borrower prior to any date on which any payment is due to the Banks
that the Borrower shall not make such payment in full, the Agent may assume that
the Borrower has made such payment in full to the Agent on such date and the
Agent may, in reliance upon such assumption, cause to be distributed to each
Bank on such date an amount equal to the amount then due such Bank. If and to
the extent the Borrower shall not have so made such payment in full to the
Agent, each Bank shall repay to the Agent forthwith on demand such amount
distributed to such Bank, together with interest thereon from the date such
amount is distributed to such Bank until the date such Bank repays such amount
to the Agent, at an interest rate equal to, the Federal Funds Rate in effect
from time to time, provided that with respect to such Bank, if such amount is
not repaid by such Bank by the end of the second day after the date of the
Agent's demand, the interest rates specified above shall be increased by a per
annum amount equal to 2.00% on the third day after the date of the Agent's
demand and shall remain at such increased rate thereafter.

      (e SHARING OF PAYMENTS. Each Bank agrees that if it should receive any
payment (whether by voluntary payment, by realization upon security, by the
exercise of the right of setoff or banker's lien, by counterclaim or cross
action, by the enforcement of any right under the Credit Documents, or
otherwise) in respect of any obligation of the Borrower to pay principal,
interest, fees, or any other obligation incurred under the Credit Documents in a
proportion greater than the total

                                      -34-
<PAGE>
amount of such principal, interest, fees, or other obligation then owed and due
by the Borrower to such Bank bears to the total amount of principal, interest,
fees, or other obligation then owed and due by the Borrower to all of the Banks
immediately prior to such receipt, then such Bank receiving such excess payment
shall purchase for cash without recourse from the other Banks an interest in the
obligations of the Borrower to such Banks in such amount as shall result in a
participation by all of the Banks, in proportion with the Banks' respective pro
rata shares, in the aggregate unpaid amount of principal, interest, fees, or any
such other obligation, as the case may be, owed by the Borrower to all of the
Banks; provided that if all or any portion of such excess payment is thereafter
recovered from such Bank, such purchase shall be rescinded and the purchase
price restored to the extent of such recovery, in proportion with the Banks'
respective pro rata shares, but without interest.

      (f AUTHORITY TO CHARGE ACCOUNTS. The Agent, if and to the extent payment
owed to the Agent or any Bank is not made when due, may charge from time to time
against any account of the Borrower with the Agent any amount so due. The Agent
agrees promptly to notify the Borrower after any such charge and application
made by the Agent provided that the failure to give such notice shall not affect
the validity of such charge and application.

      (g INTEREST AND FEES. Unless expressly provided for in this Agreement, all
computations of interest and fees shall be made on the basis of a 360 day year,
in each case for the actual number of days (including the first day, but
excluding the last day) occurring in the period for which such interest or fees
are payable; provided, however, that if the use of a 360 day year would cause
the interest contracted for, charged, or received hereunder to exceed the
Highest Lawful Rate, such computations shall instead be made on the basis of a
year of 365 or 366 days, as the case may be. Each determination by the Agent of
an interest rate or fee shall be conclusive and binding for all purposes, absent
manifest error.

      (h PAYMENT DATES. Whenever any payment shall be stated to be due on a day
other than a Business Day, such payment shall be made on the next succeeding
Business Day, and such extension of time shall in such case be included in the
computation of payment of interest or fees, as the case may be. If the time for
payment for an amount payable is not specified in this Agreement or in any other
Credit Document, the payment shall be due and payable on demand by the Agent or
the applicable Bank.

      2.11  TAXES.

      (a NO DEDUCTION FOR CERTAIN TAXES. Any and all payments by the Borrower
shall be made free and clear of and without deduction for any and all present or
future taxes, levies, imposts, deductions, charges, or withholdings, and all
liabilities with respect thereto, other than taxes imposed on the income of and
franchise taxes imposed on the Agent, any Bank, or the Applicable Lending Office
thereof by any jurisdiction in which any such entity is a citizen or resident or
any political subdivision of such jurisdiction (all such nonexcluded taxes,
levies, imposts, deductions, charges, withholdings, and liabilities being
hereinafter referred to as "Taxes"). If the Borrower shall be required by law to
deduct any Taxes from or in respect of any sum payable to the Agent, any Bank,
or the Applicable Lending Office thereof, (i) the sum payable shall be increased
as may be necessary so that, after making all required deductions (including
deductions applicable to additional sums payable under this Section 2.11), such
Person receives an amount equal to the sum it would have received had no such
deductions been made; (ii) the Borrower shall make such deductions; and (iii)
the Borrower shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable law.

      (b OTHER TAXES. The Borrower agrees to pay any present or future stamp or
documentary taxes or any other excise or property taxes, charges, or similar
levies which arise from any payment made or from the execution, delivery, or
registration of, or otherwise with respect to, this Agreement or the other
Credit Documents (other than those which become due as a result of any Bank
joining this Agreement as a result of any Assignment and Acceptance, which shall
be paid by the Bank which becomes a Bank hereunder as a result of such
Assignment and Acceptance).

      (c FOREIGN BANK WITHHOLDING EXEMPTION. Each Bank and Issuing Bank that is
not incorporated under the laws of the United States of America or a state
thereof agrees that it shall deliver to the Borrower and the Agent (i) two duly
completed copies of United States Internal Revenue Service Form 1001 or 4224 or
successor applicable form, as the case may be, certifying in each case that such
Bank is entitled to receive payments under this Agreement and the Notes payable
to it, without deduction or withholding of any United States federal income
taxes, (ii) if applicable, an Internal Revenue Service Form W-8 or W-9 or
successor applicable form, as the case may be, to establish an exemption from
United States backup withholding tax, and (iii) any other governmental forms
which are necessary or required under an applicable tax treaty or otherwise by
law to reduce or eliminate any withholding tax, which have been reasonably
requested by the Borrower. Each Bank which delivers to the Borrower and the
Agent a Form 1001 or 4224 and Form W-8 or W-9 pursuant to the next preceding
sentence further undertakes to deliver to the Borrower and the Agent two further
copies of the said letter and Form 1001 or 4224 and Form W-8 or W-9, or
successor applicable forms, or other manner of certification, as the case may
be, on or before the date that any such letter or form expires or becomes
obsolete or after the occurrence of any event requiring a change in the most
recent letter and form previously delivered by it to the Borrower and the Agent,
and such extensions or renewals thereof as may reasonably be requested by the
Borrower and the Agent certifying in the case of a Form 1001 or 4224 that such
Bank is entitled to receive payments under this Agreement without deduction or
withholding of any United States federal income taxes. If an event (including
without limitation any change in treaty, law or regulation) has occurred prior
to the date on which any delivery required by the preceding sentence would
otherwise be required which renders all such forms inapplicable or which would
prevent any

                                      -36-
<PAGE>
Bank from duly completing and delivering any such letter or form with respect to
it and such Bank advises the Borrower and the Agent that it is not capable of
receiving payments without any deduction or withholding of United States federal
income tax, and in the case of a Form W-8 or W-9, establishing an exemption from
United States backup withholding tax, such Bank shall not be required to deliver
such letter or forms. The Borrower shall withhold tax at the rate and in the
manner required by the laws of the United States with respect to payments made
to a Bank failing to provide the requisite Internal Revenue Service forms in a
timely manner. Each Bank which fails to provide to the Borrower in a timely
manner such forms shall reimburse the Borrower upon demand for any penalties
paid by the Borrower as a result of any failure of the Borrower to withhold the
required amounts that are caused by such Bank's failure to provide the required
forms in a timely manner.

      5.3   INSPECTION.

            (a) Prior to the occurrence of the Borrowing Base Termination
Condition, each Bank (by any of its officers, employees or agents) shall have
the right (which right shall not be exercised more than once during any calendar
quarter so long as no Event of Default shall have occurred and be continuing),
to the extent that the exercise of such right shall be within the control of any
Credit Party, at any time or times during normal business hours to (i) visit the
properties of any Credit Party, inspect the Collateral and the other assets of
any Credit Party and inspect and make extracts from the books and records of any
Credit Party, including, but not limited to, management letters prepared by
independent accountants, all during customary business hours at such premises,
(ii) discuss any Credit Party's business, assets, liabilities, financial
condition, results of operations and business prospects, insofar as the same are
reasonably related to the rights of the Agents or the Banks hereunder or under
any of the Credit Documents, with any Credit Party's (A) principal officers, (B)
independent accountants and other professionals providing services to any Credit
Party, and (C) any other Person (except that any such discussion with any third
parties shall be conducted only in accordance with the Bank's standard operating
procedures relating to the maintenance of confidentiality of confidential
information of borrowers and the Borrower shall have received prior written
notice of, and the opportunity to participate in, any such discussion with any
independent accountant, any other professional, or any other Person), and (iii)
verify the amount, quantity, value and condition of, or any other matter
relating to, any of the Collateral and in this connection to review, audit and
make extracts from all records and files related to any of the Collateral. Each
Credit Party will deliver or cause to be delivered to such Bank any instrument
necessary to authorize an independent accountant or other professional to have
discussions of the type outlined above with such Bank or for such Bank to obtain
records from any service bureau maintaining records on behalf of such Credit
Party.

            (b) Following the occurrence of the Borrowing Base Termination
Condition, the Borrower shall cause each Restricted Entity to permit the Agent
and the Banks to visit and inspect any of the properties of such Restricted
Entity, to examine all of such Person's books of account, records, reports, and
other papers, to make copies and extracts therefrom, and to discuss their
respective affairs, finances, and accounts with their respective officers,
employees, and independent public accountants all at such reasonable times and
as often as may be reasonably requested provided that the Borrower is given at
least one Business Day advance notice thereof and reasonable opportunity to be
present when independent public accountants or other third parties are
contacted.

      5.4 USE OF PROCEEDS. The proceeds of Advances and Letters of Credit shall
be used by the Borrower only for general corporate and working capital purposes,

      5.5 FINANCIAL COVENANTS. The Agent shall determine compliance with the
following financial covenants based upon the most recent financial statements

(plus, without duplication, the consolidated Adjusted EBITDA for such period of
any Person or assets acquired by the Borrower by Acquisition during such period
to the extent permitted or required below), to be greater than the amounts set
forth in the table below for the corresponding periods set forth below:

same business as the Borrower or any of the Restricted Entities, and (vi) the
transaction is not hostile, as reasonably determined by the Majority Banks;

      (c) any Restricted Entity organized under a jurisdiction of the United
States may sell, lease, assign, transfer, or otherwise dispose of any or all of

      (d) the Borrower and the other Restricted Entities may sell Property (i)
in the ordinary course of business, (ii) in an amount not to exceed in the

permit any other Restricted Entity to enter into any transaction directly or
indirectly with or for the benefit of an Affiliate except transactions with an
Affiliate for the leasing of property, the rendering or receipt of services, or

      5.16 ENVIRONMENTAL COMPLIANCE. The Borrower shall and shall cause each
Restricted Entity to comply with all Environmental Laws and obtain and comply
with all related permits necessary for the ownership and operation of any such
Person's properties which the failure to comply with could reasonably be

each Restricted Entity to promptly disclose to the Banks any notice to or
investigation of such Persons for any violation or alleged violation of any
Environmental Law in connection with any such Person's presently or previously
owned properties which represent liabilities which could reasonably be expected

Restricted Entity to pay and discharge, before the same shall become delinquent,
(a) all taxes, assessments, levies, and like charges imposed upon any such
Person or upon any such Person's income, profits, or property by authorities

thereto except for tax payments being contested in good faith for which adequate
reserves have been made and reported in accordance with GAAP and which could not
reasonably be expected to have a Material Adverse Effect, (b) all lawful claims
which are secured by or which, if unpaid, would by law become secured by a Lien
upon any such Person's property, and (c) all trade payables and current
operating liabilities, unless the same are less than 90 days past due or are

Restricted Entities whose stock is not pledged to the Agent exceeds 5% of the
consolidated assets of the Borrower, the Borrower shall, within 30 days of the
earlier of knowledge of such excess by the Borrower or notice from the Agent,
provide Pledge Agreements with respect to additional foreign Subsidiaries
sufficient to cure such excess to the reasonable satisfaction of the Agent. In
connection with the foregoing, the Borrower shall provide corporate
documentation and opinion letters reasonably satisfactory to the Agent

to the Borrower's receipt of notice to the contrary from the Agent, make
withdrawals from the Revenue Accounts to pay operating costs and expenses or to
other bank accounts used to pay operating costs and expenses. After the
Borrower's receipt of notice from the Agent, all amounts deposited in the
Revenue Accounts shall be applied to the payment of the Secured Obligations or
retained by the Agent as collateral for the Obligations. The Agent does not
waive or relinquish any of its rights or interests arising under the Credit

under this Agreement and the Credit Documents, irrespective of whether or not
the Agent or such Bank shall have made any demand under this Agreement or the
Credit Documents and although such obligations may be contingent and unmatured.
The Agent and each Bank, as the case may be, agrees promptly to notify the
Borrower after any such setoff and application made by such party provided that
the failure to give such notice shall not affect the validity of such setoff and
application.

      6.7 ACTIONS UNDER CREDIT DOCUMENTS. Following an Event of Default, the

course of dealing and no delay in exercising any right, power, or remedy
conferred to the Agent or the Banks in this Agreement and the Credit Documents,

            than reimbursement obligations with respect to draws under Letters
            of Credit), and indemnifications of the Agent that are due and
            payable under the Credit Documents;

            Then, ratably to the payment of the costs, expenses, reimbursements
            (other than reimbursement obligations with respect to draws under

            Obligations not yet due and payable shall be promptly paid over to
            the Borrower or to whomever may be lawfully entitled to receive such
            surplus. All applications shall be distributed in accordance with
            Section 2.10(a).

ARTICLE 7.  THE AGENT AND THE ISSUING BANK

      7.1 AUTHORIZATION AND ACTION. Each Bank hereby appoints and authorizes the
Agent to

                                      -54-
<PAGE>
take such action as agent on its behalf and to exercise such powers under this
Agreement as are delegated to the Agent by the terms hereof and of the other
Credit Documents, together with such powers as are reasonably incidental
thereto. Statements under the Credit Documents that the Agent may take certain
actions, without further qualification, means that the Agent may take such
actions with or without the consent of the Banks or the Majority Banks, but
where the Credit Documents expressly require the determination of the Banks or
the Majority Banks, the Agent shall not take any such action without the prior
written consent thereof. As to any matters not expressly provided for by this
Agreement or any other Credit Document (including, without limitation,
enforcement or collection of the Notes), the Agent shall not be required to
exercise any discretion or take any action, but shall be required to act or to
refrain from acting (and shall be fully protected in so acting or refraining
from acting) upon the written instructions of the Majority Banks, and such
instructions shall be binding upon all Banks and all holders of Notes; provided,
however, that the Agent shall not be required to take any action which exposes
the Agent to personal liability or which is contrary to this Agreement, any
other Credit Document, or applicable law.

      7.2 RELIANCE, ETC. Neither the Agent, the Issuing Bank, nor any of their
respective Related Parties (for the purposes of this Section 7.2, collectively,
the "Indemnified Parties") shall be liable for any action taken or omitted to be
taken by any Indemnified Party under or in connection with this Agreement or the
other Credit Documents, INCLUDING ANY INDEMNIFIED PARTY'S OWN NEGLIGENCE, except
for any Indemnified Party's gross negligence or willful misconduct. Without
limitation of the generality of the foregoing, the Agent and the Issuing Bank:
(a) may treat the payee of any Note as the holder thereof until the Agent
receives written notice of the assignment or transfer thereof signed by such
payee and in form satisfactory to the Agent; (b) may consult with legal counsel
(including counsel for the Borrower), independent public accountants, and other
experts selected by it and shall not be liable for any action taken or omitted
to be taken in good faith by it in accordance with the advice of such counsel,
accountants, or experts; (c) makes no warranty or representation to any Bank and
shall not be responsible to any Bank for any statements, warranties, or
representations made in or in connection with this Agreement or the other Credit
Documents; (d) shall not have any duty to ascertain or to inquire as to the
performance or observance of any of the terms, covenants, or conditions of this
Agreement or any other Credit Document on the part of the Credit Parties or to
inspect the property (including the books and records) of the Credit Parties;
(e) shall not be responsible to any Bank for the due execution, legality,
validity, enforceability, genuineness, sufficiency, or value of this Agreement
or any other Credit Document; and (f) shall incur no liability under or in
respect of this Agreement or any other Credit Document by acting upon any
notice, consent, certificate, or other instrument or writing (which may be by
telecopier or telex) reasonably believed by it to be genuine and signed or sent
by the proper party or parties.

      7.3 AFFILIATES. With respect to its Commitments, the Advances made by it,
its interests in the Letters of Credit, and the Notes issued to it, the Agent
and the Issuing Bank shall have the same rights and powers under this Agreement
as any other Bank and may exercise the same as though it were not the Agent. The
term "Bank" or "Banks" shall, unless otherwise expressly indicated, include the
Agent and the Issuing Bank in their individual capacity. The Agent, the Issuing
Bank, and their respective Affiliates may accept deposits from, lend money to,
act as trustee under indentures of, and generally engage in any kind of business
with, any Credit Party, and any Person who may do business with or own
securities of any Credit Party, all as if the Agent were not an agent

                                      -55-
<PAGE>
hereunder and the Issuing Bank were not the issuer of Letters of Credit
hereunder and without any duty to account therefor to the Banks.

      7.4 BANK CREDIT DECISION. Each Bank acknowledges that it has,
independently and without reliance upon the Agent or any other Bank and based on
the Initial Financial Statements and such other documents and information as it
has deemed appropriate, made its own credit analysis and decision to enter into
this Agreement. Each Bank also acknowledges that it shall, independently and
without reliance upon the Agent or any other Bank and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own credit decisions in taking or not taking action under this Agreement.

      7.5 EXPENSES. To the extent not paid by the Borrower, each Bank severally
agrees to pay to the Agent and the Issuing Bank on demand such Bank's ratable
share of the following: (a) all reasonable out-of-pocket costs and expenses of
the Agent and the Issuing Bank in connection with the preparation, execution,
delivery, administration, modification, and amendment of this Agreement and the
other Credit Documents, including the reasonable fees and expenses of outside
counsel for the Agent and the Issuing Bank with respect to advising the Agent
and the Issuing Bank as to their respective rights and responsibilities under
this Agreement and the Credit Documents, and (b) all out-of-pocket costs and
expenses of the Agent and the Issuing Bank in connection with the preservation
or enforcement of the rights of the Agent, the Issuing Bank, and the Banks under
this Agreement and the other Credit Documents, whether through negotiations,
legal proceedings, or otherwise, including fees and expenses of counsel for the
Agent and the Issuing Bank. The provisions of this paragraph shall survive the
repayment and termination of the credit provided for under this Agreement and
any purported termination of this Agreement which does not expressly refer to
this paragraph.

      7.6 INDEMNIFICATION. To the extent not reimbursed by the Borrower, each
Bank severally agrees to protect, defend, indemnify, and hold harmless the
Agent, the Issuing Bank, and each of their respective Related Parties (for the
purposes of this Section 7.6, collectively, the "Indemnified Parties"), from and
against all demands, claims, actions, suits, damages, judgments, fines,
penalties, liabilities, settlements, and out-of-pocket costs and expenses,
including reasonable costs of attorneys and related costs of experts such as
accountants (collectively, the "Indemnified Liabilities"), actually incurred by
any Indemnified Party which are related to any litigation or proceeding relating
to this Agreement, the Credit Documents, or the transactions contemplated
thereunder, INCLUDING ANY INDEMNIFIED LIABILITIES CAUSED BY ANY INDEMNIFIED
PARTY'S OWN NEGLIGENCE, but not Indemnified Liabilities which are a result of
any Indemnified Party's gross negligence or willful misconduct. The provisions
of this paragraph shall survive the repayment and termination of the credit
provided for under this Agreement and any purported termination of this
Agreement which does not expressly refer to this paragraph.

      7.7 SUCCESSOR AGENT AND ISSUING BANK. The Agent or the Issuing Bank may
resign at any time by giving written notice thereof to the Banks and the
Borrower and may be removed at any time with or without cause by the Majority
Banks upon receipt of written notice from the Majority Banks to such effect.
Upon receipt of notice of any such resignation or removal, the Majority Banks
shall have the right to appoint a successor Agent or Issuing Bank with the
consent of the Borrower, which consent shall not be unreasonably withheld. If no
successor Agent or Issuing Bank shall have been

                                      -56-
<PAGE>
so appointed by the Majority Banks with the consent of the Borrower, and shall
have accepted such appointment, within 30 days after the retiring Agent's or
Issuing Bank's giving of notice of resignation or the Majority Banks' removal of
the retiring Agent or Issuing Bank, then the retiring Agent or Issuing Bank may,
on behalf of the Banks and the Borrower, appoint a successor Agent or Issuing
Bank, which shall be, in the case of a successor agent, a commercial bank
organized under the laws of the United States of America or of any State thereof
and having a combined capital and surplus of at least $500,000,000 and, in the
case of the Issuing Bank, a Bank. Upon the acceptance of any appointment as
Agent or Issuing Bank by a successor Agent or Issuing Bank, such successor Agent
or Issuing Bank shall thereupon succeed to and become vested with all the
rights, powers, privileges, and duties of the retiring Agent or Issuing Bank,
and the retiring Agent or Issuing Bank shall be discharged from any duties and
obligations under this Agreement and the other Credit Documents after such
acceptance, except that the retiring Issuing Bank shall remain the Issuing Bank
with respect to any Letters of Credit outstanding on the effective date of its
resignation or removal and the provisions affecting the Issuing Bank with
respect to such Letters of Credit shall inure to the benefit of the retiring
Issuing Bank until the termination of all such Letters of Credit. After any
Agent's or Issuing Bank's resignation or removal hereunder as Agent or Issuing
Bank, the provisions of this Article 7 shall inure to such Person's benefit as
to any actions taken or omitted to be taken by such Person while such Person was
Agent or Issuing Bank under this Agreement and the other Credit Documents.

ARTICLE 8.  MISCELLANEOUS.

      8.1 EXPENSES. The Borrower shall pay on demand of the applicable party
specified herein (a) all reasonable out-of-pocket costs and expenses of the
Agent and the Issuing Bank in connection with the preparation, execution,
delivery, administration, modification, and amendment of this Agreement and the
other Credit Documents, including the reasonable fees and expenses of outside
counsel for the Agent and the Issuing Bank, but not for each Bank, and (b) all
out-of-pocket costs and expenses of the Agent, the Issuing Bank, and each Bank
in connection with the preservation or enforcement of their respective rights
under this Agreement and the other Credit Documents following any Event of
Default, whether through negotiations, legal proceedings, or otherwise,
including fees and expenses of counsel for the Agent, the Issuing Bank, and each
Bank. The provisions of this paragraph shall survive the repayment and
termination of the credit provided for under this Agreement and any purported
termination of this Agreement which does not expressly refer to this paragraph.

      8.2   INDEMNIFICATION.

      (a) The Borrower agrees to protect, defend, indemnify, and hold harmless
the Agent, the Issuing Bank, each Bank, and each of their respective Related
Parties (for the purposes of this Section 8.2, collectively, the "Indemnified
Parties"), from and against all demands, claims, actions, suits, damages,
judgments, fines, penalties, liabilities, settlements, and out-of-pocket costs
and expenses, including reasonable costs of attorneys and related costs of
experts such as accountants (collectively, the "Indemnified Liabilities"),
actually incurred by any Indemnified Party which are related to any litigation
or proceeding relating to this Agreement, the Credit Documents, or the
transactions contemplated thereunder, INCLUDING ANY INDEMNIFIED LIABILITIES
CAUSED BY ANY INDEMNIFIED PARTY'S OWN NEGLIGENCE, but not Indemnified

                                      -57-
<PAGE>
Liabilities which are a result of any Indemnified Party's gross negligence or
willful misconduct. The provisions of this paragraph shall survive the repayment
and termination of the credit provided for under this Agreement and any
purported termination of this Agreement which does not expressly refer to this
paragraph.

      (b) Within a reasonable period of time after any Indemnified Party
receives actual notice of the assertion of any claim or the commencement of any
action, or any threatened claim or action, which is covered by this Section 8.2,
such Indemnified Party shall, if indemnification with respect thereof is
intended to be sought from the Borrower under this Section 8.2, notify the
Borrower of such claim or action; provided that the failure to so notify the
Borrower shall not relieve the Borrower from any liability which the Borrower
may have to such Indemnified Party hereunder. If any such claim or action shall
be brought or threatened against an Indemnified Party by a third party, the
Borrower shall be entitled to participate in the defense thereof so long as no
Event of Default exists. No consent order or settlement shall be entered into by
an Indemnified Party with respect to any such third party claim or action prior
to notification of and consultation with the Borrower, so long as no Event of
Default exists; provided that the failure to so notify or consult with the
Borrower shall not relieve the Borrower from any liability which the Borrower
may have to such Indemnified Party hereunder.

      8.3 MODIFICATIONS, WAIVERS, AND CONSENTS. No modification or waiver of any
provision of this Agreement or the Notes, nor any consent required under this
Agreement or the Notes, shall be effective unless the same shall be in writing
and signed by the Agent and Majority Banks and the Borrower, and then such
modification, waiver, or consent shall be effective only in the specific
instance and for the specific purpose for which given; provided, however, that
no modification, waiver, or consent shall, unless in writing and signed by the
Agent, all the Banks, and the Borrower do any of the following: (a) waive any of
the conditions specified in Section 3.1 or 3.2, (b) increase the Commitments of
the Banks, (c) forgive or reduce the amount or rate of any principal, interest,
fees, or other amounts payable under the Credit Documents, or postpone or extend
the time for payment thereof, (d) release any Guaranty or any material amount of
collateral securing the Credit Obligations, or (e) change the percentage of
Banks required to take any action under this Agreement, the Notes, or the other
Credit Documents, including any amendment of the definition of "Majority Banks"
or of this Section 8.3; PROVIDED however that upon any Permitted Sale of
Property constituting collateral securing the Credit Obligations, the liens
securing such collateral shall be released by the Agent in accordance with
Section 4.05 of the Security Agreements, without requirement for the consent of
the Banks. No modification, waiver, or consent shall, unless in writing and
signed by the Agent or the Issuing Bank affect the rights or obligations of the
Agent or the Issuing Bank, as the case may be, under the Credit Documents. The
Agent shall not modify or waive or grant any consent under any other Credit
Document if such action would be prohibited under this Section 8.3 with respect
to the Credit Agreement or the Notes.

      8.4 SURVIVAL OF AGREEMENTS. All representations, warranties, and covenants
of the Borrower in this Agreement and the Credit Documents shall survive the
execution of this Agreement and the Credit Documents and any other document or
agreement.

      8.5 ASSIGNMENT AND PARTICIPATION. This Agreement and the Credit Documents
shall bind and inure to the benefit of the Borrower and their respective
successors and assigns and the Agent and the Banks and their respective
successors and assigns. The Borrower may not assign its rights

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

the obligations which by the terms of this Agreement are required to be

<PAGE>
copy of each Assignment and Acceptance delivered to and accepted by it and a
register for the recordation of the names and addresses of the Banks and the
Commitments of each Bank from time to time (the "Register"). The entries in the
Register shall be conclusive and binding for all purposes, absent manifest
error, and the Borrower, the Agent, the Issuing Bank, and the Banks may treat
each Person whose name is recorded in the Register as a Bank hereunder for all
purposes of this Agreement. The Register shall be available for inspection by

assignment, the Agent shall, if such Assignment and Acceptance has been
completed in the appropriate form, (i) accept such Assignment and Acceptance,
(ii) record the information contained therein in the Register, and (iii) give
prompt notice thereof to the Borrower. Within five Business Days after its
receipt of such notice, the Borrower shall execute and deliver to the Agent in
exchange for the surrendered Notes a new Note to the order of such Eligible
Assignee in an amount equal to the Commitment assumed by it pursuant to such
Assignment and Acceptance and, if such Bank has retained any Commitment
hereunder, a new Note to the order of such Bank in an amount equal to the
Commitment retained by it hereunder. Such new Notes shall be dated the effective
date of such Assignment and Acceptance and shall be in the appropriate form.

      (e) PARTICIPATION. Each Bank may sell participations to one or more banks
or other entities in or to all or a portion of its rights and obligations under
this Agreement (including, without limitation, all or a portion of its
Commitments, the Advances owing to it, its participation interest in the Letters
of Credit, and the Notes held by it); provided, however, that (i) such Bank's

obligations, (iii) such Bank shall remain the holder of any such Notes for all

such Bank shall not require the participant's consent to any matter under this
Agreement, except for change in the principal amount of the Notes, reductions in

      16b-3 promulgated under the Act ("Rule l6b-3") no amendment to the Plan
      shall be adopted without further approval by the holders of at least a
      majority of the shares of Common Stock present, or represented, and
      entitled to vote at a meeting held for such purpose, and provided further,
      that if and to the extent required for the Plan to comply with Rule 16b-3,
      no amendment to the Plan shall be made more than once in any six-month
      period that would change the amount, price or timing of the grants of
      Awards or Stock Options hereunder other than to comport with changes in
      the Code, ERISA, or the regulations thereunder.

      The Plan may be terminated at any time by the Board or by the approval by
      the holders of at least a majority of the shares of Common Stock present,
      or represented, and entitled to vote at a meeting held for such purpose.

Section 12. Withholding Taxes

      No later than the date as of which an amount first becomes includible in
      the gross income of the Participant for Federal income tax purposes with
      respect to any Award under the Plan or with respect to any exercise of any
      Stock Option granted under the Plan, the Participant shall pay to the
      Company, or make arrangements satisfactory to the Company regarding the
      payment of, any Federal, state, local or foreign taxes of any kind
      required by law to be withheld. Such withholding obligations may be
      settled with Common Stock, including Common Stock that is part of the
      Award or that is received upon the exercise of the Stock Option that gives
      rise to the withholding requirement. The obligations of the Company under
      the Plan shall be conditional upon such payment or arrangements, and the
      Company shall, to the extent permitted by law, have the right to deduct
      any such taxes from any payment otherwise due to the Participant. The
      Company may establish such procedures as it deems appropriate, including
      the making of irrevocable elections or the timing of the use of Common
      Stock, for the settlement of its withholding obligations.

Section 13. Effect of Change in Control

      Notwithstanding any other provision of the Plan to the contrary, in the
      event of a Change in Control, any Stock options outstanding and not then
      exercisable and vested as of the date such Change in Control is determined
      to have occurred, shall become fully exercisable and vested to the full
      extent of the original grant. During the 60-day period from and after a
      change in Control (the "Exercise Period"), a Participant who holds an
      Award or a Stock Option shall have the right, in lieu (in the case of a
      Stock Option) of the payment of the exercise price for the shares of
      Common Stock being purchased under the Stock option, by giving notice to
      the Company, to elect (within the Exercise Period) to surrender all or
      part
<PAGE>
      of an Award or a Stock Option to the Company and to receive cash, within
      30 days of such notice, in an amount equal to (a) in the case of a Stock
      Option, the amount by which the Change in Control Price per share of
      Common Stock on the date of such election shall exceed the exercise price
      per share of Common Stock under the Stock Option (the "Spread") multiplied
      by the number of shares of Common Stock granted under the Stock Option as
      to which the right granted under this Section shall have been exercised,
      or (b) in the case of an Award, an amount equal to the Change in Control
      Price multiplied by the number of shares of Common Stock granted pursuant
      to such Award as to which the right granted under this Section shall have
      been exercised. Notwithstanding the foregoing, if any right granted
      pursuant to this Section 13 would make a Change on Control transaction
      ineligible for pooling-of-interests accounting under APB No. 16 that but
      for the nature of such grant would otherwise be eligible for such
      accounting treatment, the Board shall have the ability to substitute for
      the cash payable pursuant to such right Common Stock with a Fair Market
      Value equal to the cash that would otherwise be payable hereunder.

Section 14. Effect of Termination for Cause

      If a Participant incurs a termination of membership on the Board for
      cause, such Participant's Stock Options shall be automatically cancelled
      immediately. Unless otherwise determined by the Board, for purposes of the
      Plan "cause" shall mean (i) the conviction of the Participant for
      commission of a felony under Federal law or the law in the state in which
      such action occurred, or (ii) dishonesty in the course of fulfilling the
      Participant's duties as a director.

Section 15. Adjustments Upon Changes in Capitalization

      In the event of any change in corporate capitalization, such as a stock
      split or a corporate transaction, such as any merger, consolidation,
      separation, including a spin-off, or other distribution of stock or
      property of the Company, any reorganization (whether or not such
      reorganization comes within the definition of such term in Section 368 of
      the Code) or any partial or complete liquidation of the Company, the
      Committee or Board may make such substitution or adjustments in the
      aggregate number and class of shares reserved for issuance under the Plan,
      in the number, kind and option price of shares subject to outstanding
      Stock Options, in the number and kind of shares subject to other
      outstanding Awards granted under the Plan and/or such other equitable
      substitution or adjustments as it may determine to be appropriate in its
      sole discretion; provided, however, that the number of shares subject to
      any Award shall always be a whole number.

Section 16. Regulatory Matters

      The Plan is intended to be construed so that participation in the Plan
      will be exempt from Section 16(b) of the Act, pursuant to Rule 16b-3 as
      promulgated thereunder, as may be further amended or interpreted by the
      Securities and Exchange Commission. In the event that any provision of the
      Plan shall be deemed not to be in compliance with the Rules in order to
      enjoy the exemption from the Act, such provision shall be deemed of no
      force or effect and the remaining provisions of the Plan shall remain in
      effect.
