          2.1. Loans.

          (a) (i) Loans Prior to Maturity  Date.  From and including the date of
          this  Agreement and prior to the Maturity  Date,  each Bank  severally
          agrees,  subject  to the  terms  and  conditions  set  forth  in  this
          Agreement,  to make Loans to the Company  from time to time in amounts
          not to exceed in the aggregate at any one time  outstanding the amount
          of its Available  Commitment.  Subject to the terms of this Agreement,
          the  Company may  borrow,  repay and  reborrow up to the amount of the
          Aggregate Available Commitment at any time prior to the Maturity Date.

          (ii) Loans Upon Draws Under the Second Facility  Letter of Credit.  So
          long as (A) there  exists no Unmatured  Default or Default  under this
          Agreement both before and immediately  after giving effect to any such
          loan, (B) the Second  Facility  Letter of Credit has been  terminated,
          (C) there has been a draw under the Second  Facility Letter of Credit,
          and (D) each Bank has received a duly  completed  and executed  Second
          Facility Loan Note, and subject to the terms of this  Agreement,  each
          Bank severally  agrees to make a term Loan to the Company in an amount
          not to exceed in the  aggregate,  the draw under the  Second  Facility
          Letter of Credit (the "Second Facility  Loan").  Amounts repaid by the
          Company  under  the  Second  Facility  Loan  are  not  entitled  to be
          reborrowed by the Company.

         (b) Ratable Loans.  Each Advance  hereunder shall consist of Loans made
  from  the  several  Banks  ratably  in  proportion  to the  ratio  that  their
  respective Commitments bear to the Aggregate Commitment.

         (c) Rate Options;  Interest  Period  Payments.  Each Advance shall bear
  interest  at either the  Floating  Rate,  the Fixed CD Rate or the  Eurodollar
  Rate, as the Company may select in accordance with the terms of Section 2.l(h)
  of this  Agreement.  Each Advance  shall be paid in full by the Company on the
  last day of the Interest Period applicable thereto.

          (d) Interest Recapture. If at any time the applicable rate of interest
  under the Agreement on any portion of the Obligations (the "Designated  Rate")
  exceeds the Highest  Lawful Rate, the rate of interest on any Advance shall be
  limited to the Highest  Lawful  Rate,  but any  subsequent  reductions  in the
  Designated  Rate  shall not  reduce  the rate of  interest  thereon  below the
  Highest  Lawful  Rate  until the total  amount of  interest  paid and  accrued
  thereon equals the amount of interest which would have accrued  thereon if the
  Designated Rate had at all times been in effect. In the event that at maturity
  (stated  or  by  acceleration  or  otherwise),  or at  final  payment  of  the
  Obligations,  the total  amount of interest  paid and accrued is less than the
  amount of interest which would have accrued if the Designated  Rate had at all
  times been in effect,  then, at such time and to the extent  permitted by law,
  the Company shall pay to the Banks an amount equal to the  difference  between
  (i) the  lesser of the amount of  interest  which  would  have  accrued if the
  Designated  Rate had at all times been in effect  and the  amount of  interest
  which would have  accrued if the Highest  Lawful Rate had at all times been in
  effect, and (ii) the amount of interest actually paid on the Obligations.

          (e) Mandatory Principal Payments.

                (i) If the  Company  shall grant or  implement a material  price
           decrease in MTS Service and the Company shall fail to  demonstrate to
           the  satisfaction  of the Required  Banks,  by projections  employing
           revised revenue  forecasts based upon such price decrease that, after
           giving effect  thereto,  the Company will be in  compliance  with the
           provisions of Section 7.4 for the remaining  term of this  Agreement,
           then the Company shall either (i) make a mandatory  prepayment on the
           Advances  outstanding in such amount as the Required Banks shall deem
           necessary to accomplish compliance with the provisions of Section 7.4
           or (ii) furnish the Banks with cash  collateral in such amount as the
           Required  Banks  shall deem  satisfactory.  Mandatory  payments  made
           pursuant to this Section 2.1.(e)(i) may not be reborrowed.

                (ii)  Upon  any  reduction  in  the   Aggregate   Commitment  in
           accordance with the terms of Section 2.1(f) below,  the Company shall
           immediately  pay any  amount  necessary  to  reduce  the  outstanding
           Obligations  to an  amount  equal  to or  less  than  the  sum of the
           Aggregate  Available  Commitment  plus the Second  Facility Letter of
           Credit or Second  Reimbursement  Obligations,  together with interest
           and fees accrued through such date on such amount repaid.

                (iii) All  outstanding  Obligations  shall be due and payable in
           full on the Maturity Date.

                (iv)  The  Company  may from  time to time  pay all  outstanding
           Floating  Rate  Advances,  or,  in  a  minimum  aggregate  amount  of
           $100,000,  or any  integral  multiple  thereof,  any  portion  of the
           outstanding  Floating  Rate  Advances  upon one Business  Day's prior
           notice  to the  Administrative  Agent  without  penalty  or  premium.
           Subject to the terms of Section  4.3,  the  Company  may from time to
           time pay all Fixed Rate Advances,  or, in a minimum  aggregate amount
           of  $1,000,000,  or any  integral  multiple  of  $100,000  in  excess
           thereof,  any portion of the  outstanding  Fixed Rate  Advances  upon
           three Business Days' prior written notice.

                (v)  All  Reimbursement  Obligations  and  Second  Reimbursement
           Obligations  shall  be due  and  payable  on the  earlier  of (A) the
           Maturity Date or (B) demand by the Administrative Agent.

                (vi) If at any time the Company or any  Subsidiary  sells assets
           or properties not in the ordinary  course of business,  which, in the
           aggregate  for any fiscal year of the Company,  exceeds a gross sales
           price of $500,000, the Company shall immediately make a prepayment on
           the Second Facility Loan (or, if the Second Facility Letter of Credit
           shall not have been drawn upon,  the Company  shall  establish a cash
           collateral  account  with the  Administrative  Agent to secure a draw
           against the Second  Facility  Loan) in an amount equal to 100% of the
           net  proceeds  of each such sale until the Second  Facility  Loan has
           been repaid in full (or is 100% cash collateralized).

         (f) Reduction of Commitment

           (i)  Optional.  The  Company  may  permanently  reduce the  Aggregate
         Commitment in whole,  or in part ratably  among the Banks,  in integral
         multiples of $500,000,  upon at least ten Business Days' written notice
         to the Administrative Agent, which shall specify the amount of any such
         reduction,   provided,  however,  that  the  amount  of  the  Aggregate
         Commitment may not be reduced below the outstanding principal amount of
         the Advances  outstanding  thereunder.  No  reduction in the  Aggregate
         Commitment shall reduce the Facility Letter of Credit Commitment unless
         (A) there are no outstanding Facility Letters of Credit and (B) (I) the
         Company shall designate such Aggregate  Commitment reduction in writing
         to  apply to the  Facility  Letter  of  Credit  Commitment  or (II) the
         Facility  Letter  of  Credit  Commitment  shall be the only part of the
         Aggregate  Commitment  that has not been  reduced to zero.  All accrued
         fees shall be payable on the effective  date of any  termination of the
         Aggregate Commitment.

           (ii) Mandatory.

                (A) Scheduled Reduction.  Notwithstanding any other provision of
         this  Agreement   reducing  the  Aggregate   Commitment  or  otherwise,
         commencing  June 30,  1993 and on each  Payment  Date  thereafter,  the

         forth  opposite the  applicable  Payment Date below until the Aggregate
         Commitment is reduced to zero. the Aggregate  Commitment shall never be
         less  than  zero.  Once  reduced,  the  Aggregate  Commitment  (or  the

          June 30, 1996                                              $650,000
          September 30, 1996                                         $650,000
          December 31, 1996                                          $650,000
          March 31, 1997                                             $812,500
          June 30, 1997                                              $812,500
          September 30, 1997                                         $812,500
          December 31, 1997                            All remaining amounts in
                                                       excess of zero

                    (B) Asset Sales. After the Second Facility Loan is repaid in
          full,  if at any time the Company or any  Subsidiary  sells  assets or
          properties  not in the  ordinary  course of  business,  which,  in the
          aggregate  for any fiscal year of the  Company,  exceeds a gross sales
          price of  $500,000,  the  Aggregate  Commitment  shall be  immediately
          reduced by an amount  equal to 100% of the net  proceeds  of each such
          sale until the Aggregate Commitment is zero.

                    (C) Expiration of Facility  Letters of Credit.  At such time
          as the  Company  permits  all of the  Facility  Letters  of  Credit to
          terminate according to their terms (or such Facility Letters of Credit
          are  replaced  or  substituted  by  Letters  of  Credit  issued  by an
          institution other than  Administrative  Agent), the Facility Letter of
          Credit Commitment shall be reduced to zero.

                    (D) Maturity  Date. The Aggregate  Commitment,  the Facility
          Letter  of  Credit  Commitment  and each  Bank's  Commitment  shall be
          reduced immediately to zero on the Maturity Date.

                    (E)  Expiration  of Second  Facility  Letter of Credit.  The
          Second  Facility  Letter of  Credit  Commitment  shall be  immediately
          reduced to zero on June 30, 1996.

          (g)  Method of  Borrowing.  Not later  than noon  Dallas  time on each
  Borrowing  Date,  each Bank  shall make  available  its Loan or Loans in funds
  immediately  available in Dallas, to the  Administrative  Agent at its address
  specified  on  the   signature   pages  or  to  such  other   address  as  the
  Administrative  Agent requests in writing.  The Administrative Agent will make
  the  funds  so  received  from  the  Banks  available  to the  Company  at the
  Administrative   Agent's   address   set  forth  in   Section   11.18   below.
  Notwithstanding the foregoing provisions of this Section, to the extent that a
  Loan made by a Bank matures on the Borrowing  Date of a requested  Loan,  such
  Bank shall apply the  proceeds of the Loan it is then making to the  repayment
  of the maturing Loan.

          (h) Method of Selecting Rate Options and Interest Periods. The Company
  shall select the Rate Option and Interest  Period  applicable  to each Advance
  from time to time. The Company shall give the Administrative Agent irrevocable
  notice (a  "Borrowing  Notice") to Ms.  Linda  Brown,  telephone  number (214)
  508-3044  (facsimile number (214) 508-2020),  not later than 10:00 a.m. Dallas
  time at least one Business Day before the Borrowing Date of each Floating Rate
  Advance,  two Business  Days before the  Borrowing  Date of each Fixed CD Rate
  Advance and three Business Days before the Borrowing  Date of each  Eurodollar
  Advance, specifying:

           (i) the  Borrowing  Date,  which  shall be a  Business  Day,  of such
               Advance,

           (ii)the aggregate  amount of such Advance and whether such Advance is
               made under the Aggregate Commitment or the Second Facility Loan,

           (iii) the Rate Option selected for such Advance, and

           (iv)in the case of each  Fixed  Rate  Advance,  the  Interest  Period
               applicable thereto.

  Each Fixed Rate Advance  shall bear  interest from and including the first day
  of the Interest Period applicable  thereto to (but not including) the last day
  of such Interest  Period at the interest rate determined as applicable to such
  Fixed Rate Advance.  The Company may not select a Fixed Rate for an Advance if
  there exists a Default or Unmatured Default. The Company shall select Interest
  Periods with respect to Fixed Rate Advances so that it is not necessary to pay
  a Fixed Rate Advance prior to the last day of the applicable  Interest  Period
  in order to repay Advances  because of a mandatory  reduction of the Aggregate
  Commitment pursuant to Section 2.1(f) of this Agreement, or a repayment of the
  Second Facility Loan as provided in Section 2.l(n) hereof.

           (i) Minimum Amount of Each Advance.  Each Fixed Rate Advance shall be
  in the minimum amount of $1,000,000 (and in multiples of $100,000 if in excess
  thereof),  and each Floating  Rate Advance  shall be in the minimum  amount of
  $100,000  (and in  multiples  of  $100,000  if in excess  thereof),  provided,
  however,  that any  Floating  Rate  Advance may be in the amount of the unused
  Aggregate Available Commitment.

           (j) Rate after  Default.  Except as  provided  in the next  sentence,
  after the occurrence and during the  continuance of any Default,  all Advances
  outstanding  hereunder  shall bear  interest  until paid in full at a rate per
  annum equal to the lesser of (i) the  Highest  Lawful Rate and (ii) the sum of
  the  Eurodollar  Rate,  the  Fixed  CD Rate  or the  Floating  Rate  otherwise
  applicable  thereto,  plus two percent per annum. No Fixed Rate Advance may be
  selected by the Company after the occurrence and during the continuance of any
  Default.  In the  case of a Fixed  Rate  Advance  the  maturity  of  which  is
  accelerated,  such Fixed Rate Advance shall bear interest for the remainder of
  the applicable  Interest Period,  at the lesser of (i) the Highest Lawful Rate
  and (ii) the higher of (A) the sum of the rate  otherwise  applicable  to such
  Interest Period plus two percent per annum or (B) the Floating Rate plus three
  percent per annum.

           (k) Notes;  Telephonic  Notices.  Each Bank is hereby  authorized  to
  record the  principal  amount of each of its Loans and each  repayment  on the
  schedule attached to its Note provided, however, that the failure to so record
  shall not affect the Company's obligations under such Note. The Company hereby
  authorizes  the Banks and the  Administrative  Agent to  extend  Advances  and
  effect Rate Option  selections based on telephonic  notices made by any person
  or persons the  Administrative  Agent or any Bank in good faith believes to be
  an Authorized  Officer acting on behalf of the Company.  The Company agrees to
  deliver promptly to the  Administrative  Agent a written  confirmation of each
  telephonic notice signed by an Authorized Officer. If the written confirmation
  differs in any material  respect  from the action taken by the  Administrative
  Agent and the Banks,  the  records of the  Administrative  Agent and the Banks
  shall govern absent manifest error.

          (l) Interest Payment Dates;  Interest Basis.  Interest accrued on each
  Advance shall be payable on the last day of its applicable Interest Period and
  on any date on which the Advance is prepaid,  whether due to  acceleration  or
  otherwise.  Interest  accrued on each Fixed Rate  Advance  having an  Interest
  Period  longer than three months shall also be payable on the last day of each
  three-month  interval during such Interest  Period.  Interest on Floating Rate
  Advances shall be calculated for actual days elapsed on the basis of a 365, or
  when appropriate 366, day year; interest on Fixed Rate Advances and fees shall
  be calculated for actual days elapsed on the basis of a 360-day year. Interest
  shall be  payable  for the day an  Advance  is made but not for the day of any
  payment on the amount paid if payment is received  prior to noon (Dallas time)
  at the place of  payment.  If any  payment of  principal  of or interest on an
  Advance  shall become due on a day which is not a Business  Day,  such payment
  shall  be made on the  next  succeeding  Business  Day  and,  in the case of a
  principal  payment,  such  extension  of time shall be included  in  computing
  interest in connection  with such payment,  provided  that, if any  Eurodollar
  Loan extension shall be payable in the next calendar month,  then such payment
  shall be made on the next preceding Business Day.

           (m)  Notification  of  Advances,   Interest  Rates,  Prepayments  and
  Commitment  Reductions.  Promptly after receipt  thereof,  the  Administrative
  Agent will  notify  each Bank of the  contents  of each  Aggregate  Commitment
  reduction  notice,  Borrowing  Notice  and  repayment  notice  received  by it
  hereunder. The Administrative Agent will notify each Bank of the interest rate
  applicable  to each Fixed Rate Advance  promptly  upon  determination  of such
  interest  rate and will  give each Bank  prompt  notice of each  change in the
  Corporate Base Rate.

          (n) Repayment of the Second  Facility Loan.  The Second  Facility Loan
  shall be repaid in  installments  on the  following  dates in the  amounts set
  forth opposite such dates:

                  Date                                 Amount Due

           December 31, 1997                75% of Initial Amount of Second 
                                                Facility Loan and all other 
                                                Obligations

          (o) Lending Installations. Each Bank may book its Loans at any Lending
  Installation  selected  by such Bank and may change its  Lending  Installation
  from time to time. All terms of this Agreement shall apply to any such Lending
  Installation  and the Notes  shall be deemed held by each Bank for the benefit
  of such Lending  Installation.  Each Bank may, by written,  telex, or telecopy
  notice  to the  Administrative  Agent  and the  Company,  designate  a Lending
  Installation through which Loans will be made by it and for whose account Loan
  payments are to be made.

                   2.2.  Participation  in Facility Letters of Credit and Second
          Facility Letter of Credit.  Each Bank severally  agrees,  on the terms
          and conditions set forth in this Agreement and pursuant to Article III
          hereof,  to  purchase  on the date  hereof  (or on the date  such Bank
          became  a party  to this  Agreement)  participations  in the  Facility
          Letter of Credit  Commitment and the Second Facility Letters of Credit
          Commitment and in each of the Facility  Letters of Credit,  the Second
          Facility  Letters  of  Credit,  Reimbursement  Obligations  and Second
          Reimbursement  Obligations  in an  aggregate  amount not to exceed its
          ratable portion (based upon the ratio such Bank's  Commitment bears to
          the Aggregate Commitment) of the aggregate undrawn face amount of each
          of the  Facility  Letters  of Credit  and  Second  Facility  Letter of
          Credit.

                   2.3. Fees.  The Company  agrees to pay to the  Administrative
          Agent the following fees:

                  (a) subject to Section 11.17  hereof,  for the account of each
                      Bank, a commitment fee equal to 1/2 of 1% per annum on the
                      daily unused  portion of such Bank's  Commitment  from the
                      date hereof to and  including the Maturity  Date,  payable
                      hereafter as it accrues on each Payment Date hereafter and
                      on the Maturity Date;

                  (b) subject to Section 11.17 hereof,  for the ratable  account
                      of each Bank, a per annum fee on each  Facility  Letter of
                      Credit  equal to 2% of the face  amount  of each  Facility
                      Letter of Credit,  payable in accordance  with Section 3.2
                      below;

                  (c) subject to Section  11.17 hereof,  for the  Administrative
                      Agent's  own  account,  such other fees as the Company and
                      the Administrative Agent shall have heretofore agreed upon
                      in writing, dated the date hereof (the "Fee Letter"), and

                  (d) subject to Section 11.17 hereof,  for the ratable  account
                      of each  Bank,  a per  annum  fee on the  Second  Facility
                      Letter  of  Credit  equal to 2% of the face  amount of the
                      Second  Facility  Letter of Credit,  payable in accordance
                      with Section 3.2 below.

                   2.4. Method of Payment. All payments of principal,  interest,
          and fees hereunder shall be made in immediately available funds to the
          Administrative  Agent at the  Administrative  Agent's  address  on the
          signature pages hereto or as otherwise  specified  pursuant to Section
          11.18   hereof  or  at  any   other   Lending   Installation   of  the
          Administrative  Agent specified in writing by the Administrative Agent
          to the Company,  by noon (Dallas  time) on the date when due and shall
          be made  ratably  among  the  Banks.  Each  payment  delivered  to the
          Administrative  Agent for the  account of any Bank shall be  delivered
          promptly by the Administrative  Agent to such Bank in the same type of
          funds which the Administrative Agent received at its address specified
          pursuant  to  Section  11.18  hereof  or at any  Lending  Installation
          specified in a notice received by the  Administrative  Agent from such
          Bank.  The  Administrative  Agent is hereby  authorized  to charge the
          account of the Company maintained with NationsBank for each payment of
          principal, interest and fees as it becomes due hereunder.

                   2.5 Non-Receipt of Funds by the Administrative  Agent. Unless
          the Company or a Bank, as the case may be, notifies the Administrative
          Agent prior to the date on which it is  scheduled  to make  payment to
          the Administrative Agent of (a) in the case of a Bank, the proceeds of
          a Loan or (b) in the case of the  Company,  a  payment  of  principal,
          interest  or fees to the  Administrative  Agent for the account of the
          Banks,   that  it  does  not   intend  to  make  such   payment,   the
          Administrative  Agent may assume that such payment has been made.  The
          Administrative  Agent  may,  but  shall not be  obligated  to make the
          amount of such payment available to the intended recipient in reliance
          upon such assumption. If such Bank or the Company, as the case may be,
          has not in fact made such  payment to the  Administrative  Agent,  the
          recipient  of such  payment  shall,  on demand  by the  Administrative
          Agent, repay to the Administrative  Agent the amount so made available
          together  with  interest  thereon  in  respect  of each day during the
          period commencing on the date such amount was so made available by the
          Administrative  Agent until the date the Administrative Agent recovers
          such amount at a rate per annum equal to (a) in the case of payment by
          a Bank,  the  federal  funds rate for such day (as  determined  by the
          Administrative  Agent) or (b) in the case of payment  by the  Company,
          the interest rate applicable to the relevant Loan.

         SECTION  4.  ARTICLE  III.  ARTICLE  III on pages 23  through 27 of the
  Credit  Agreement  is hereby  amended and  restated in its entirety to read as
  follows:

         3.1. Issuance of Letters of Credit

         (a) Issuance of Facility Letters of Credit.  The Company shall give the
  Issuer not less than three Business Days prior written notice of a request for
  the issuance of a Facility  Letter of Credit.  Until the Maturity  Date,  upon
  receipt of the Company's properly completed and duly executed Applications and
  subject to the terms of such  Applications and to the terms of this Agreement,
  the Issuer agrees to issue Facility Letters of Credit on behalf of the Company
  in an  aggregate  face  amount  not in  excess  of  Facility  Letter of Credit
  Commitment  at any one time  outstanding.  No Facility  Letter of Credit shall
  have a maturity  extending  beyond the earliest of (i) the Maturity  Date,  or
  (ii) such earlier date as may be required to enable the Company to satisfy its
  repayment  obligations  under Section 2.1(e) hereof.  Subject to such maturity
  limitations and so long as no Default or Unmatured Default has occurred and is
  continuing  or would  result from the renewal of a Facility  Letter of Credit,
  the Facility Letters of Credit may be renewed by the Issuer in its discretion.
  The Banks shall  participate  in any liability  under the Facility  Letters of
  Credit and in any unpaid Reimbursement Obligations of the Company with respect
  to any Facility  Letter of Credit ratably  according to the  percentage  their
  Commitment  bears to the  Aggregate  Commitment.  The  amount of the  Facility
  Letters  of  Credit  issued  and  outstanding  and  the  unpaid  Reimbursement
  Obligations  of the Company for such  Facility  Letters of Credit shall reduce
  the amount of  Aggregate  Commitment  available,  so that at no time shall the
  aggregate   outstanding  Advances  together  with  the  sum  of  Reimbursement
  Obligations plus the face amount of all outstanding Facility Letters of Credit
  exceed an amount equal to the Aggregate  Commitment,  and at no time shall the
  sum of all Loans by any Bank,  plus its ratable share of amounts  available to
  be drawn under the  Facility  Letters of Credit and its  ratable  share of the
  unpaid  Reimbursement  Obligations  of the Company in respect of such Facility
  Letters of Credit, exceed its ratable percentage of the Aggregate Commitment.

         (b) Issuance of Second  Facility  Letter of Credit.  The Company  shall
  give the Issuer not less than three  Business Days prior  written  notice of a
  request  for the  issuance  of the  Second  Facility  Letter  of Credit or any
  increase  thereto.  Until  October 31,  1995,  upon  receipt of the  Company's
  properly  completed and duly executed  Application and subject to the terms of
  such  Application  and to the terms of this  Agreement,  the Issuer  agrees to
  issue the  Second  Facility  Letter of Credit on behalf of the  Company  in an
  aggregate face amount not in excess of $9,100,000 at any one time outstanding.
  Until June 20, 1996, upon receipt of the Company's properly completed and duly
  executed  Application and subject to the terms of such  Application and to the
  terms of this  Agreement,  the  Issuer  agrees to  replace or amend the Second
  Facility Letter of Credit on behalf of the Company to an aggregate face amount
  not in excess of Second Facility  Letter of Credit  Commitment at any one time
  outstanding.  The Second  Facility  Letter of Credit shall not have a maturity
  extending  beyond  June  30,  1996 and may not be  renewed.  The  Banks  shall
  participate in any liability under the Second Facility Letter of Credit and in
  any unpaid Second Reimbursement Obligations of the Company with respect to the
  Second  Facility  Letter of Credit ratably  according to the percentage  their
  Commitment bears to the Aggregate Commitment.

         3.2. Letter of Credit Fee.

         (a) Facility Letter of Credit Fees. In  consideration  for the issuance
  of each Facility Letter of Credit and any renewal  thereof,  the Company shall
  pay to the  Administrative  Agent for the account of the Issuer and the Banks,
  ratably in accordance with the percentage that their  Commitment  bears to the
  Aggregate  Commitment,  a letter of credit fee as set forth in Section  2.3(b)
  hereof.  The letter of credit fee shall  accrue  from the date of  issuance of
  each  Facility  Letter of Credit and shall be payable  quarterly in arrears on
  each Payment Date and on the date of  termination  of such Facility  Letter of
  Credit, and upon the Issuer's demand pursuant to Section 3.3 hereof.

         (b) Second  Facility  Letter of Credit  Fee. In  consideration  for the
  issuance of the Second Facility Letter of Credit and any renewal thereof,  the
  Company  shall pay to the  Administrative  Agent for the account of the Issuer
  and the Banks, ratably in accordance with the percentage that their Commitment
  bears to the  Aggregate  Commitment,  a letter of  credit  fee as set forth in
  Section 2.3(d) hereof.  The letter of credit fee shall accrue from the date of
  issuance  of the  Second  Facility  Letter  of  Credit  and  shall be  payable
  quarterly in arrears on each Payment  Date and on the date of  termination  of
  the Second Facility Letter of Credit, and upon the Issuer's demand pursuant to
  Section 3.3 hereof.

          3.3.  Reimbursement   Obligations  and  Second  Reimbursement
          Obligations.

         (a) The Company hereby agrees to reimburse the Issuer, immediately upon
 demand by the Issuer,  and in immediately  available  funds, for any payment or
 disbursement  made by the  Issuer  under any  Facility  Letter of Credit or the
 Second  Facility  Letter of Credit.  Payment  shall be made by the Company with
 interest on the amount so paid or  disbursed  by the Issuer from and  including
 the date  payment  is made  under any  Facility  Letter of Credit or the Second
 Facility Letter of Credit to and including the date of payment, at the Floating
 Rate in effect  from time to time  plus  three  percent  per  annum;  provided,
 however, that (a) with respect to any draw under any Facility Letter of Credit,
 if the  Company  would be  permitted  under the terms of Section  2.1 to borrow
 Advances  in  amounts  at least  equal to its  reimbursement  obligation  for a
 drawing under any Facility Letter of Credit, a Floating Rate Loan by each Bank,
 ratably in an amount equal to the percentage that such Bank's  Commitment bears
 to the Aggregate Commitment,  shall automatically be deemed made on the date of
 any such  payment  or  disbursement  made by the  Issuer in the  amount of such
 obligation and subject to the terms of this Agreement,  and (b) with respect to
 any draw under the Second  Facility  Letter of Credit,  subject to the terms of
 this  Agreement,  the Company  may be  entitled to borrow a term-loan  from the
 Banks in the form of a Second  Facility  Loan in  accordance  with the terms of
 this Agreement.

          (b) The Company  hereby also agrees to pay to the Issuer,  immediately
  upon demand by the Issuer and in immediately  available funds, as security for
  its reimbursement obligations in respect of the Facility Letters of Credit and
  Second  Facility  Letter of Credit under  Section  3.3(a) hereof and any other
  amounts  payable  hereunder and under the Notes, an amount equal to the sum of
  the aggregate  amount  available to be drawn under Facility  Letters of Credit
  and  the  Second  Facility  Letter  of  Credit  then   outstanding   plus  any
  Reimbursement Obligations and Second Reimbursement  Obligations,  irrespective
  of whether any of the Facility Letters of Credit or the Second Facility Letter
  of Credit has been drawn upon,  at the  occurrence  of a Default or  Unmatured
  Default. Any such payments shall be deposited in a separate account designated
  "GCIC Special  Account" or such other  designation  as the Issuer shall elect.
  All such amounts  deposited with the Issuer shall be and shall remain funds of
  the  Company on deposit  with the Issuer and may be  invested by the Issuer as
  the Issuer shall determine.  Such amounts may not be used by the Issuer to pay
  the  drawings  under the  Facility  Letters of Credit and the Second  Facility
  Letter  of  Credit;  however,  such  amounts  may be  used  by the  Issuer  as
  reimbursement  for  Facility  Letter of Credit  or Second  Facility  Letter of
  Credit  drawings which the Issuer has paid.  During the existence of a Default
  or an Unmatured  Default but after the expiry of any Facility Letter of Credit
  or Second  Facility  Letter of Credit that was not drawn upon, the Company may
  direct  the  Administrative  Agent  to use any  cash  collateral  for any such
  expired Facility Letter of Credit or Second Facility Letter of Credit, if any,
  to prepay  Advances in accordance  with Section 2.1. Any amounts  remaining in
  the GCIC Special Account after the date of the expiry of all Facility  Letters
  of Credit and the Second  Facility  Letter of Credit and after all Obligations
  have been paid in full,  shall be repaid to the  Company  promptly  after such
  expiry and such payment in full.

         (c) The obligations of the Company under this Section 3.3 will continue
  until all Facility  Letters of Credit and the Second Facility Letter of Credit
  have  expired  and all  Reimbursement  Obligations  and  Second  Reimbursement
  Obligations  with  respect  thereto  have been paid in full by the Company and
  until all of the other Obligations shall have been paid in full.

         (d) The Company  shall be obligated to reimburse the Issuer upon demand
  for all amounts paid under the Facility  Letters of Credit and Second Facility
  Letter of Credit as set forth in Section 3.3(a) hereof; provided,  however, if
  the Company for any reason fails to reimburse  the Issuer in full upon demand,
  whether by borrowing  Advances to pay such Reimbursement  Obligations,  Second
  Reimbursement  Obligations or otherwise,  the Banks shall reimburse the Issuer
  ratably in accordance with  percentage that each Bank's ratable  percentage of
  the Commitment bears to the Aggregate  Commitment,  for amounts due and unpaid
  from the Company as set forth in Section 3.4 hereof;  provided,  however, that
  no  such  reimbursement  made  by the  Banks  shall  discharge  the  Company's
  obligations to reimburse the Issuer.

         (e) The Company shall  indemnify  and hold the Issuer or any Bank,  its
  officers, directors,  representatives and employees harmless from loss for any
  claim,  demand or liability  which may be asserted  against the Issuer or such
  indemnified  party in connection with actions taken under the Facility Letters
  of Credit or the Second  Facility  Letter of  Credit,  or in  connection  with
  either thereof  (including  losses resulting from the negligence of the Issuer
  or such  indemnified  party),  and shall pay the Issuer for reasonable fees of
  attorneys  (who may be  employees  of the  Issuer)  and  legal  costs  paid or
  incurred by the Issuer in connection  with any matter  related to the Facility
  Letters of Credit or the Second Facility  Letter of Credit,  except for losses
  and liabilities incurred as a direct result of the gross negligence or willful
  misconduct  of the Issuer or such  indemnified  party.  If the Company for any
  reason fails to indemnify or pay the Issuer or such  indemnified  party as set
  forth  herein in full,  the Banks  shall  indemnify  and pay the  Issuer  upon
  demand,  ratably in  accordance  with each Bank's  percentage of the Aggregate
  Commitment,  such amounts due and unpaid from the Company.  The  provisions of
  this Section 3.3(e) shall survive the termination of this Agreement.

         3.4.  Banks'  Obligations.   Each  Bank  agrees,   unconditionally  and
         irrevocably  to  reimburse  the Issuer (to the extent the Issuer is not
         otherwise  reimbursed by the Company in accordance  with Section 3.3(a)
         hereof) on demand for such Bank's ratable  percentage  according to the
         percentage  that  such  Bank's   Commitment   bears  to  the  Aggregate
         Commitment of each draw paid by the Issuer under any Facility Letter of
         Credit or the Second Facility Letter of Credit.  All amounts payable by
         any Bank under this subsection  shall include  interest  thereon at the
         Federal Funds  Effective  Rate, from the date of the applicable draw to
         the date of reimbursement by such Bank. No Bank shall be liable for the
         performance  or  nonperformance  of the  obligations  of any other Bank
         under this  Section.  The  obligations  of the Banks under this Section
         shall continue after the Maturity Date and shall survive termination of
         any Loan Documents.

         3.5. The Issuer's Obligations.

         (a) The Issuer  makes no  representation  or  warranty,  and assumes no
   responsibility  with  respect  to  the  validity,  legality,  sufficiency  or
   enforceability of any Application or any document relative thereto, or to the
   collectibility  thereunder.  The  Issuer  assumes no  responsibility  for the
   financial  condition of the Company or for the  performance of any obligation
   of the Company.  The Issuer may use its discretion with respect to exercising
   or refraining from exercising any rights, or taking or refraining from taking
   any action  which may be vested in it or which it may '  entitled  to take or
   assert with respect to any  Facility  Letter of Credit,  the Second  Facility
   Letter of Credit or any Application.

         (b) The Issuer shall be under no liability to any Bank, with respect to
   anything  the Bank  may do or  refrain  from  doing  in the  exercise  of its
   judgment, the sole liability and responsibility of the Issuer being to handle
   each Bank's share on as favorable a basis as the Issuer handles its own share
   and to  promptly  remit to each  Bank its share of any sums  received  by the
   Issuer   under  any   Application.   The  Issuer  shall  have  no  duties  or
   responsibilities except those expressly set forth herein and those duties and
   liabilities shall be subject to the limitations and  qualifications set forth
   herein.

         (c) Neither the Issuer nor any of its directors, officers, or employees
   shall be liable for any action  taken or omitted  (whether or not such action

   under or in  connection  herewith  or any other  instrument  or  document  in
   connection herewith,  except for gross negligence or willful misconduct.  The
   Issuer shall incur no liability to any Bank or the Company in acting upon any
   notice, document,  order, consent,  certificate,  warrant or other instrument
   believed  by the Issuer to be genuine  or  authentic  and to be signed by the
   proper party.

          Credit,  unless  on the  applicable  Borrowing  Date  or the  date  of

                   (e) All legal matters  incident to the making of such Advance
                       shall be satisfactory  to the Banks and their  respective

          conditions   contained  in  Sections   5.2(a)  and  5.2(b)  have  been
          satisfied.   Any  Bank  may  require  a  duly   completed   Compliance
