"Prime Rate"), plus one and three-quarters percent (1.75%) per annum.

     (b)  Subject  to the  terms  and  conditions  hereof,  from the date of the
Promissory  Note in respect  of the  Omniplex  Loan,  the  Principal  Sum of the
Omniplex Loan shall bear interest  until the Omniplex  Maturity Date and payment
in full of the Omniplex  Loan at a rate equal to the Prime Rate plus two percent
(2%) per annum.

     (c) Each  change in the Prime  Rate  shall  automatically  and  immediately
change  the  interest  rate on all  advances  under  the  Equalnet  Loan and the
Omniplex Loan without notice to the Borrower.  All interest  payments under this
Agreement  shall be calculated on a 360-day year basis and shall be based on the
actual number of days that elapse during the interest calculation period.

     5.  Expenses.  Borrower  shall pay upon demand  therefor all  out-of-pocket
expenses of Lender associated with the negotiation, preparation and execution of
this Agreement,  including but not limited to, Lender's  reasonable  legal fees,
audit fees,  appraisal fees and banking fees related  hereto.  All such expenses
shall be netted on the date of this Agreement against the Loan proceeds or added
to the Principal Sum, as the case may be.

     6. Payment of Principal and Interest.

     (a) The  Principal  Sum of the Equalnet  Loan,  or so much thereof as shall
have been advanced by Lender at any time and not thereafter repaid, plus any and
all accrued and unpaid  interest shall be  immediately  due and payable upon the
Stated  Maturity,  whether by demand,  acceleration  or otherwise.  In addition,
accrued  interest on the Equalnet Loan shall be payable by Borrower to Lender on
a monthly  basis in arrears on the first day of each month;  provided,  however,
that one and  three-quarters  percent of the interest due and payable  under the
Equalnet Loan shall be deferred during the period  beginning on the Closing Date
and ending on April 2, 2002, and repaid in equal monthly installments during the
period beginning on April 3, 2002 and ending on April 2, 2003.

     (b) The  Principal  Sum of the Omniplex  Loan,  or so much thereof as shall
have been advanced by Lender at any time and not thereafter repaid, plus any and
all accrued and unpaid  interest shall be  immediately  due and payable upon the
Omniplex  Maturity  Date,  whether  by demand,  acceleration  or  otherwise.  In
addition,  all collections  received through the Lockbox Account and the Blocked
Account in respect of the customers relating to Borrower's  purchase of Omniplex
assets shall be applied to the  Principal  Sum of the Omniplex  Loan,  beginning
June 1,  2005.  Furthermore,  accrued  interest  on the  Omniplex  Loan shall be
payable by Borrower to Lender on a monthly  basis in arrears on the first day of
each month;  provided however that interest on the Principal Sum of the Omniplex
Loan during the period from August 30, 2001, to February 28, 2002,  shall be due
and payable in six (6) equal consecutive monthly  installments,  beginning March
1,  2002,  and  continuing  through  and  including  August 1,  2002.  Each such
installment  shall be in the  amount  of 1/6 of the  amount of the  accrued  and
unpaid  interest on the  Principal  Sum of the Omniplex  Loan as of February 28,
2002.  Except for the period set forth in the  immediately  preceding  sentence,
Lender  shall  apply  all  collections,  as of the date  they are  received  and
collected in the Lockbox,  first against any fees or other charges,  then second
against  accrued  interest,  and then third against the Principal Sum, until all
amounts due under the Loan are paid in full.  The interest rates accruing on the
Principal  Sum of the Equalnet  Loan and the Omniplex  Loan, as the case may be,
shall be separately and collectively termed the "Interest Rates."

     (c) Upon the occurrence of an Event of Default,  including, but not limited
to, an event where an installment of interest or the unpaid principal balance is
not  received  by Lender on or before the date such  payment is due, at Lender's
sole discretion and in addition to Lender's other rights hereunder, Lender shall
have the right,  without any further  notice or demand for payment,  to increase
the applicable Interest Rates to a rate or rates equal to five percentage points


                                      8





(5%) in excess of rate of interest in effect  immediately prior to such Event of
Default.  Upon the occurrence of an Event of Default, at Lender's option, Lender
may add any unpaid accrued interest to the Principal Sum, and such sum will bear
interest  therefrom  until paid at the rate  provided for herein  including  any
increased  Interest  Rates.  In  addition,  in such  event  Borrower  agrees  to
immediately  suspend  the payment of any and all cash  bonuses to any  director,
officer and/or management personnel until such time as Borrower is in compliance
with the terms and conditions of this Agreement.

      7.    Payment.

     (a)  Borrower  shall  expressly  instruct  all of its end  users  and other
payors, including master payors on credit card receipts, to remit payment to the
Lockbox  Account.  Pursuant to this Agreement  and/or the execution of any other
documentation  in connection  herewith or with respect to the Lockbox Account or
the Blocked Account,  Borrower hereby  authorizes  Lender to withdraw funds from
the  Lockbox  Account in order to  satisfy  any  Obligations  then due and owing
Lender by Borrower,  and, to the extent such available  funds are not sufficient
to satisfy the Obligations then due and owing Lender, Borrower shall immediately
remit such payment to Lender,  by wire  transfer,  in lawful money of the United
States of America,  to an account  designated by Lender, or in the event no such
account  has  been  identified,  by  certified  check  payable  to  RFC  Capital
Corporation and delivered at 130 East Chestnut Street, Suite 400, Columbus, Ohio
43215,  Attention:  President or at such other place as Lender may  designate in
writing.

     (b) If Borrower fails to maintain the minimum required Availability Formula
for the Equalnet Loan or Omniplex  Borrowing  Formula for the Omniplex  Loan, as
the case may be, Borrower shall immediately pay to Lender such difference.

      8.    Prepayment; Termination.

     (a)  Borrower may prepay the  Principal  Sum  outstanding  plus accrued but
unpaid interest on the Promissory Notes in whole or in part at any time.  Except
as otherwise  provided  herein,  the amount of any  prepayment  shall be applied
first to satisfy the payment of any fees, costs, charges or expenses incurred by
Lender  in  connection  with  this  Agreement,  including  but  not  limited  to
attorneys'  fees,  then second in reduction of accrued and unpaid  interest,  if
any, and third, in reduction of the Principal Sum.

     (b) Notwithstanding the foregoing, Borrower may terminate this Agreement in
connection  with  Borrower's  prepayment  of the entire  Principal  Sum and upon
Lender's receipt of ninety (90) days prior written notice thereof.  In the event
of any termination of this  Agreement,  Borrower shall be required to discharge,
no later than the effective date of termination,  the Principal Sum, all accrued
and unpaid  interest,  all Obligations and all other amounts owing from Borrower
to Lender  pursuant  to this  Agreement,  whether  any such  amount  and due and
payable at such time,  and any  agreement  or  document  executed  or  delivered
hereunder. The security interest created by Borrower in favor of Lender pursuant
to this Agreement,  and all other rights and remedies of Lender pursuant to this
Agreement,   shall  continue  in  full  force  and  effect  notwithstanding  any
termination of this  Agreement,  until the Principal Sum, all accrued and unpaid
interest,  all  Obligations  and all other  obligations  owing from  Borrower to
Lender are discharged in full.

     9. Use of Proceeds.

     (a) Borrower  hereby  agrees,  represents,  covenants and warrants that all
Loan  proceeds of the Equalnet  Loan received  hereunder  shall be used,  unless
otherwise  agreed  in  writing  with  Lender,   to  (i)  refinance  the  current

      14.   Reporting.

     (a) Borrower shall furnish, or cause to be furnished, to Lender:

          (i) as soon as  available,  and in any event  within 30 days after the
     end of each month of its fiscal  year, a financial  statement,  including a
     balance  sheet and  income  statement,  of  Borrower  as of the end of such
     month, commencing with the August 31, 2001 financial statements,  certified
     by the President,  Chief Executive  Officer or Controller of Borrower,  and
     accompanied by a management narrative summarizing  circumstances and issues
     underlying such results and those facing Borrower on a going forward basis;
     and

          (ii) any and all other reasonably necessary and material documentation
     that Lender may request in writing to Borrower,  including, but not limited
     to,  the  monthly  delivery  by  Borrower  to  Lender of a  Borrowing  Base
     Certificate  in the form that  Lender  shall  provide to  Borrower  and the
     monthly delivery of a Compliance Certificate, the form of which is attached
     hereto as Exhibit A.

     (b) Guarantor shall furnish, our cause to be furnished, to Lender:

          (i) as soon as  available,  and in any event within 45 days of the end
     of  each  quarter  of  its  fiscal  year,   unaudited   consolidating   and
     consolidated  financial  statements,  certified  by  the  President,  Chief
     Executive  Officer  or  Controller  of  Guarantor,  and  accompanied  by  a
     management narrative  summarizing  circumstances and issues underlying such
     results and those facing Guarantor on a going forward basis;

          (ii) as soon as available,  and in any event within 120 days after the
     end of each fiscal year (including the most recent fiscal year then ended),
     audited consolidating and consolidated  financial  statements,  prepared by
     and  accounting  firm  acceptable  to Lender,  accompanied  by a management
     narrative summarizing  circumstances and issues underlying such results and
     those facing Guarantor on a going forward basis; and

          (iii)   any  and  all  other   reasonably   necessary   and   material
     documentation  that Lender may request in writing to Guarantor,  including,
     but not limited to, the monthly delivery of a Compliance  Certificate,  the
     form of  which  is  attached  hereto  as  Exhibit  A.

     15. Indemnification  Obligations.  Borrower shall indemnify and hold Lender
harmless  from and against,  and shall pay to Lender  within ten  business  days
after Borrower's receipt of written demand from Lender, any and all liabilities,
obligations,  losses,  damages,  penalties,  costs,  and expenses of any kind or
nature  that  may  be  imposed  on  Lender  in  any  litigation,  proceeding  or
investigation instituted by any governmental authority or Person with respect to
any aspect of, or any  transaction  contemplated  by, or  referred to in, or any
matter  related to, this  Agreement;  provided,  however,  Borrower shall not be
required  to  indemnify  and hold  Lender  harmless  from any such  liabilities,
obligations,  losses,  damages,  penalties,  costs,  and  expenses  arising from
Lender's gross negligence or willful misconduct.  The failure of Borrower to pay
to Lender any such amounts as required  under this  Section  shall  trigger,  in
addition  to other  rights  and  remedies  available  to it,  Lender's  right to
exercise any of its rights and remedies as more fully set forth in Section 24 of
this Agreement.  The rights and remedies of Lender shall be cumulative,  and any
exercise  of any  right  or  remedy  under  this  Agreement  or  the  underlying


                                      17





documentation toguarantee the Obligations, shall not be deemed to be an election
of that right or remedy to the exclusion of any other right or remedy.

     16.  Further   Assurances.   Borrower   covenants  to  execute  such  other
assignments, security agreements, financing statements, and other documents that
Lender may reasonably deem necessary to further evidence the Obligations,  or to
perfect, extend, or clarify Lender's rights in the Collateral.

     17.  Insurance.  Borrower  shall keep the Inventory  and Equipment  insured
against  all risks of loss or damage from every  cause  whatsoever  for not less
than the full  replacement  value thereof,  and shall carry public liability and
property damage insurance  covering the Inventory and Equipment and their use in
amounts customary for such Inventory and Equipment.  All such insurance shall be
in form and amount acceptable to Lender and name Lender and its assignee as Loss
Payee, as their interest may appear with respect to property damage coverage and
as Additional Insured with respect to public liability coverage.  Borrower shall
pay the premiums  therefor and deliver said policies,  or duplicates  thereof or
certificates  of  coverage  therefor  to Lender,  with long form  Lender's  Loss
Payable  endorsement  upon the policy or policies or by independent  instrument,
that  provides  that no act,  default or breach of warranty or  condition of the
insured or any other person  shall  affect the right of Lender to recover  under
such policy or policies of  insurance  or to pay any premium in whole or in part
relating  thereto,  and that  provides  Lender a right to thirty (30) days prior
written notice before the policy can be altered or canceled  without  obligation
of payment of premiums.  In the event  Borrower  fails to provide such insurance
coverage,  Lender may obtain such coverage for its benefit or for the benefit of
Borrower  and charge  Borrower  therefor.  Borrower  hereby  appoints  Lender as
Borrower's  attorney-in-fact  to make claim for, receive payment of, and execute
and endorse all documents,  checks,  or drafts for loss of damage under any said
insurance  policies and to apply the proceeds in  furtherance of the exercise of
Lender's options as provided herein.

     18.  Guaranty.   Borrower   acknowledges  that  a  certain  amount  of  the
Obligations  are  guaranteed  by  Guarantor  pursuant  to a certain  amended and
restated guaranty agreement dated as of even date herewith (the "Guaranty"), the
form of which is attached hereto as Exhibit B.

     19. Audits. Lender shall have the right, in its sole discretion, to conduct
audits of Borrower up to four times  annually,  and Borrower will provide access
to all of its books and records and such other  information  which  Lender deems
necessary  to evaluate the status of the Loans or of the  Collateral;  provided,
however, that if an Event of Default occurs, Lender shall have the right, in its
sole discretion, to conduct audits of Borrower without limitation. In connection
therewith,  Borrower  will pay to  Lender  all  reasonable  costs  and  expenses
incurred in conjunction therewith.

     20. Confidentiality. Lender, Borrower and Guarantor shall hold confidential
all non-public  information  obtained  pursuant to the  requirements  hereof and
identified as such by Lender, Borrower or Guarantor in accordance with Lender's,
Borrower's  or  Guarantor's   customary  procedures  for  handling  confidential
information  of this  nature  and in  accordance  with safe and  sound  business
practices,  provided that Lender,  Borrower or Guarantor may make disclosures as
required  or  requested  by any  governmental  authority  or any  representative
thereof,  or pursuant to any legal process,  or to its accountants,  lawyers and
other advisors.

     21. Legal and Binding  Agreement.  Borrower and Guarantor  warrant that the
execution and  performance  of this  Agreement  will not violate any judicial or
administrative  order or  governmental  law or  regulation  to which  either  of
Borrower or Guarantor is subject,  and that this Agreement is valid, binding and
enforceable  against  Borrower and Guarantor in every  respect  according to its
terms subject to all applicable laws.

     22. No Consent Required. Borrower and Guarantor warrant that Borrower's and
Guarantor's  execution,  delivery and  performance  of this  Agreement  does not


                                      18





require  the consent of or the giving of notice to any third  party,  including,
but not limited to, any third party payor of accounts, any lender,  governmental
body or regulatory authority.

     23.  Default  Defined.  The  occurrence of any one or more of the following
events shall constitute a default under this Agreement ("Event of Default"):

     (a) Monetary  Default.  The failure of Borrower to pay to Lender any amount
due  hereunder or under the  Promissory  Notes within one day following the date
such amount is due and owing by Borrower to Lender.

     (b)  Default  Under Any  Other  Agreement.  A  default  under (i) any other
agreement,  document or instrument to which Borrower or Guarantor and Lender are
a party, (ii) any other agreement which one or more of Borrower's Affiliates and
Lender  or one or more of  Lender's  affiliates  are a party or (iii)  any other
agreement to which Borrower is a party,  and with respect to (i), (ii) and (iii)
which is not otherwise cured by Borrower or Guarantor, as applicable, within ten
days  following the date upon which  Borrower or Guarantor knew or in good faith
should have known of the occurrence of such Event of Default.

     (c) Breach of  Warranty/Covenant.  The failure of Borrower or  Guarantor to
perform  or observe  any  obligation,  covenant,  agreement,  representation  or
warranty  contained herein or in any document or agreement executed or delivered
in connection herewith within ten days following the date upon which Borrower or
Guarantor  knew or in good  faith  should  have known of the  occurrence  of the
breach at issue.

     (d)  Dissolution/Cessation  of Business.  The  cessation of  Borrower's  or
Guarantor's  business,  Borrower's or Guarantor's  liquidation,  the filing of a
certificate of dissolution by Borrower or Guarantor, or the taking of any action
by Borrower or Guarantor to further a liquidation or dissolution.

     (e)  Creation of Lien.  The  garnishment  or creation of a lien  against or
security  interest  in any of  the  Collateral  (other  than  existing  security
interests as of the date hereof or liens  otherwise  permitted  herein) in which
Borrower has granted a security  interest to Lender pursuant to the terms hereof
which is  otherwise  not  released  or cured by  Borrower  in some other  manner
acceptable to Lender within ten days following the date upon which Borrower knew
or in good faith should have known of the existence of the interest at issue.

     (f) Loss of Licenses.  The loss of license as a final act of any applicable
administrative  or  governmental  authority  required of Borrower to conduct its
business as presently  conducted  and as proposed to be  conducted,  unless such
loss of license would not have a Material Adverse Effect (as defined below).

     (g) Material  Change of  Personnel.  Any additions or  replacements  to the
senior management teams of Borrower or Guarantor are made without Lender's prior
written approval, which consent shall not be unreasonably withheld or delayed.

     (h) Compromise of Security. A Material Adverse Effect or a material adverse
change,  in  Lender's  reasonable  discretion,  has  occurred  in the  financial
condition,  operations or business of Borrower or Guarantor, or the value of the
Collateral or Lender's interest in such Collateral,  which has not been cured by
Borrower or Guarantor,  as  applicable,  within ten days following the date upon
which Borrower or Guarantor,  as  applicable,  knew or in good faith should have
known of the  existence  of the  Material  Adverse  Effect or  material  adverse
change.  "Material  Adverse Effect" means a material adverse effect upon (a) the
business,   condition   (financial  or  otherwise),   operations,   performance,
properties or prospects of Borrower or Guarantor, (b) the ability of Borrower or
Guarantor  to perform its  respective  obligations  under this  Agreement or any


                                      19





document, agreement, guaranty, or instrument executed in connection herewith, or
(c) the  ability  of  Lender to  enforce  the  terms of this  Agreement,  or any
document, agreement, guaranty, or instrument executed in connection herewith.

     24.  Remedies  Upon  Default.  Upon the  occurrence of an Event of Default,
after notice has been provided to Borrower by Lender in accordance  with Section
26 of this  Agreement and after the  expiration of any  applicable  cure period,
Lender may pursue any or all of the  following  remedies,  without  any  further
notice to Borrower, except as required below, to allow Lender to proceed against
the Collateral.

     (a)  Acceleration.  Lender  may  declare  the  entire  amount due under the
Promissory  Notes due and  payable at once.  The  entire  unpaid  balance  shall
continue to accrue  interest at the rate  specified in Section 6 above until all
amounts due hereunder have been paid in full.

     (b) Collection of Collateral. Upon written notice by Lender, Borrower shall
not make any further  attempt to collect or receive  payment with respect to any
of the  Collateral.  Any such  attempt  after the  giving of such  notice  shall
constitute  a  wrongful  conversion  of the  Collateral.  Lender  may  obtain  a
temporary  restraining  order or other  equitable  relief to enforce  Borrower's
obligation to refrain from so impairing Lender's interest in the Collateral.  To
the extent  Borrower  receives any  collections  or payments with respect to the
Collateral,  Borrower shall hold such collections or payments in trust on behalf
of Lender and immediately turn the same over to Lender in the form so received.

     (c)  Repossession.  Lender  may  take  possession  of  any  or  all  of the
Collateral and proceeds thereof.

     (d) Disposition.  Lender may dispose of the Collateral at private or public
sale.  Any required  notice of sale shall be deemed  commercially  reasonable if
given at least five (5) days prior to sale.  Lender  may  adjourn  any public or
private sale to a different  time or place without notice or publication of such
adjournment,  and may  adjourn  any  sale  either  before  or after  offers  are
received.

     (e)  Recovery  of  Proceeds  of  Collateral.  Lender may recover any or all
proceeds of the Collateral from any bank,  court or other custodian who may have
possession  thereof.  Borrower  hereby  authorizes and directs all custodians of
Borrower's  assets to comply with any demand for payment made by Lender pursuant
to this  Agreement,  without  the need of prior  approval or  confirmation  from
Borrower  and  without  making any  inquiry as to the  existence  of an Event of
Default  hereunder or any other matter.  Lender may engage a collection agent to
collect the Collateral for a reasonable percentage commission or under any other
reasonable compensation arrangement.

     (f)  Enforcement  of Rights of  Collection.  Lender  may,  but shall not be
obligated  to,  take such  measures  as Lender  may deem  necessary  in order to
collect or otherwise  liquidate the Collateral.  Without limiting the foregoing,
Lender may institute or continue any  administrative  or judicial action that it
may deem  necessary  in the course of  collecting  and  enforcing  any or all of
Lender's  rights in or under the  Collateral.  Any  administrative  or  judicial
action  or  other  action  taken by  Lender  in the  course  of  collecting  the
Collateral may be taken by Lender in its own name or in Borrower's name.  Lender
may compromise or settle any disputed claims,  which  compromises or settlements
shall be binding upon Borrower.  Lender shall have no duty to pursue  collection
of the Collateral,  and may abandon efforts to collect the Collateral after such
efforts are initiated. All costs and expenses related to collection shall be the
responsibility of Borrower. Any deficiency balance owed Lender by Borrower shall
be a general claim against Borrower.

     (g) Other  Remedies.  Lender may  exercise any right that it may have under
any other  document  evidencing or securing the Loans or otherwise  available to
Lender at law or equity.

     (h) Application of Proceeds. All amounts received by Lender for Borrower's

                                      20





account by  exercise  of its  remedies  hereunder  shall be applied as  follows:
first,  to the  payment of all  expenses  incurred by Lender in  exercising  its
rights hereunder,  including reasonable  attorneys' fees, and any other expenses
due Lender  from  Borrower;  second,  to the  payment of all  interest,  if any,
outstanding under the Promissory Notes in such order as Lender may elect; third,
to the payment of the Principal Sum outstanding  under the Promissory  Notes, in
such order as Lender may elect;  and,  fourth,  any excess to  Borrower or other
party entitled thereto.

     25. Not Partners; No Third Party Beneficiaries. Nothing contained herein or
in any related  document  shall be deemed to render Lender a partner of Borrower
or Guarantor  for any purpose.  This  Agreement  has been  executed for the sole
benefit of Lender and its assignees and affiliates,  and no other third party is
authorized to rely upon Lender's rights  hereunder or to rely upon an assumption
that Lender has or will  exercise its rights  under this  Agreement or under any
document referred to herein.

     26. Notices.

     (a) All  communications  regarding this  Agreement  shall be in writing and
shall be deemed to have been duly given if (i) delivered personally, (ii) mailed

facsimile, if sent in accordance with item (iii) of paragraph (a) above, and (c)

     27. Indulgence Not Waiver. Lender's indulgence in the existence of an Event
of Default  hereunder or any other  departure  from the terms of this  Agreement
shall not prejudice  Lender's rights to declare an Event of Default or otherwise
demand strict compliance with this Agreement.

     28. Cumulative Remedies. The remedies provided Lender in this Agreement are
not  exclusive of any other  remedies  that may be available to Lender under any
other document or at law or equity.

     29.  Term;  Reinstatement.  The  security  interest  granted  herein  shall
continue until all amounts due and owing  hereunder and all amounts  included in
the secured  indebtedness and secured hereby have been irrevocably paid in full.
If, after receipt of payment of all or any part of the Loans,  Lender is for any
reason  required to surrender such payment to any Person because such payment is
invalidated,  declared fraudulent,  set aside, determined to be void or voidable
as a preference or diversion of trust funds,  or for any other reason,  then the
Loans  or part  thereof  intended  to be  satisfied  shall be  revived  and this
Agreement and the security  interests  granted herein or in connection  herewith
shall  continue in full force as if such payment had not been made, and Borrower
shall be liable to  Lender,  and hereby  indemnifies  Lender  against  and holds
Lender harmless from, the amount of such surrendered  payment.  These provisions
shall remain  effective  notwithstanding  any contrary action taken by Lender in
reliance  on such  payment  which  such  action  shall be  deemed  to have  been


                                      22





conditioned on such payment having become final and irrevocable.  The provisions
of this Agreement are  irrevocable.  Upon final and  irrevocable  payment of the
Loans and all amounts  included in the secured  indebtedness  and performance of
all  of  Borrower's  obligations  hereunder,   all  filings  under  the  Uniform
Commercial  Code will be terminated  within a reasonable time and the provisions
of this Agreement shall terminate.

     30. Power of Attorney. Borrower hereby irrevocably constitutes and appoints
Lender and any officer or agent  thereof,  with full power of  substitution,  as
Borrower's  true and lawful  attorney-in-fact  with full  irrevocable  power and
authority in its place and stead and in its name or in Lender's  own name,  from
time to time in Lender's  discretion,  for the purpose of carrying out the terms
of this Agreement, to take any and all appropriate action and to execute any and
all documents and  instruments  that may be necessary or desirable to accomplish
the purposes of this  Agreement  and,  without  limiting the  generality  of the
foregoing,  hereby grants to Lender the power and right,  on behalf of Borrower,
without notice to or assent: (a) to execute,  file and record all such financing
statements,  certificates of title and other  certificates  of registration  and
operation and similar  documents and instruments as Lender may deem necessary or
desirable to protect,  perfect and validate  Lender's  security  interest in the
Collateral;  (b) to  receive,  collect,  take,  indorse,  sign,  and  deliver in
Borrower's  or  Lender's  name,  any and all  checks,  notes,  drafts,  or other
documents or instruments relating to the Collateral; and (c) upon the occurrence
of an Event of Default,  (i) to notify postal  authorities to change the address
for delivery of Borrower's mail to an address designated by Lender, (ii) to open
such mail  delivered to the  designated  address,  (iii) to sign and indorse any
invoices,  freight  or express  bills,  bills of  lading,  storage or  warehouse
receipts,  drafts against  debtors,  assignments,  verifications  and notices in
connection with accounts and other documents relating to the Collateral; (iv) to
commence and prosecute any suits,  actions or proceedings at law or in equity in
any court of  competent  jurisdiction  to  collect  the  Collateral  or any part
thereof  and to enforce  any other  right in respect of any  Collateral;  (v) to
defend any suit,  action or proceeding  brought with respect to any  Collateral;
(vi) to negotiate,  settle,  compromise or adjust any account,  suit,  action or
proceeding described above and, in connection therewith, to give such discharges
or  releases  as Lender  may deem  appropriate;  and (vii)  generally,  to sell,
transfer,  pledge, make any agreement with respect to or otherwise deal with any
of the  Collateral  as fully and  completely  as though Lender were the absolute
owner thereof for all purposes,  and to do, at Lender's  option,  at any time or
from time to time, all acts and things which Lender deems  necessary to protect,
preserve or realize  upon the  Collateral  and the  Lender's  security  interest
therein, in order to effect the intent of this Agreement.

     Borrower hereby ratifies all that said attorneys shall lawfully do or cause
to be done by virtue  hereof.  This power of attorney is a power coupled with an
interest and shall be irrevocable.  The powers  conferred upon Lender  hereunder
are solely to protect its interests in the  Collateral  and shall not impose any
duty upon Lender to exercise any such powers.  Lender shall be accountable  only
for amounts  that Lender  actually  receives as a result of the exercise of such
powers and  neither  Lender nor any of its  officers,  directors,  employees  or
agents shall be  responsible  to Borrower for any act or failure to act,  except
for Lender's own gross  negligence  or willful  misconduct,  as  determined by a
final non-appealable judgment by a court of competent jurisdiction.

     31.  Outstanding  Loans.  The outstanding  principal amount of, and accrued
interest on, the Loans and the Interest  Rate  applicable to the Loans from time
to time,  shall be, at all  times,  ascertained  from the  records of Lender and
shall be conclusive absent manifest error.

     32.  Modifications  and Course of Dealing.  This Agreement  constitutes the
entire  agreement  of  Borrower,  Lender and  Guarantor  relative to the subject
matter hereof.  No modification  of, or supplement to, this Agreement shall bind
Lender  unless in writing  and signed by an  authorized  officer of Lender.  The
enumeration in this Agreement of Lender's rights and remedies is not intended to
be exclusive,  and such rights and remedies are in addition to and not by way of
limitation  of any other  rights or  remedies  that  Lender  may have  under the
Uniform  Commercial  Code or other  applicable  law. No course of dealing and no
delay or failure of Lender to exercise any right, power or privilege under this

                                      23





Agreement,  any other loan document or any other agreement will affect any other
or future  exercise of such right,  power or privilege.  The exercise of any one
right,  power or privilege shall not preclude the exercise of any others, all of
which shall be cumulative. In the 60 days after the execution of this Agreement,
Lender  and  Borrower  agree to  negotiate  in good  faith  with the  intent  of
combining the borrowing  formulas of the various  classifications  of assets and
revenues  (net of Taxes  and  Surcharges)  of  Borrower.  Failure  to reach  any
agreement  in this  regard  shall  have no effect on the  respective  rights and
remedies of the parties to this Agreement.

     33. Assignment and Participation. Neither Borrower nor Guarantor may assign
or transfer  any of its rights or  delegate  any of its  obligations  under this
Agreement.  Lender shall have the right,  from time to time,  without  notice to
Borrower or  Guarantor,  to sell,  assign or otherwise  transfer its interest in
this Agreement and the Loans,  either in whole or in part, to any other party or
enter  into  participation  arrangements  with any  other  party.  Borrower  and
Guarantor  authorize  Lender to deliver to potential  assignees or  participants
Borrower's  and  Guarantor's  financial  information  and all other  information
delivered to Lender pursuant to the terms of this Agreement.

     34. Expenses.  Borrower agrees to pay, and to hold Lender harmless from and
against,  all  expenses  associated  with any  amendments,  waivers or  consents
relating to this  Agreement or any  agreement or document  executed or delivered
hereunder or arising in connection with Lender's  enforcement or preservation of
its rights under this Agreement,  including  expenses  incurred by Lender in the
collection of any of the Loans.

     35. Maximum Charges.  In no event shall the interest rate and other charges
hereunder  exceed  the  highest  rate  permissible  under  law  which a court of
competent jurisdiction shall, in a final determination, deem applicable thereto.
In the event such a court determines that Lender has received interest and other
charges hereunder in excess of the highest rate applicable thereto, Lender shall
promptly refund such excess amount to Borrower,  and the provisions hereof shall
be deemed amended to provide for such permissible rate.

     36. No  Consequential  Damages,  No O No claim may be made by  Borrower  or
Guarantor, or any of their officers,  directors, or agents against Lender or its
affiliates,  directors,  officers, employees, attorneys or agents for agents for
any special,  indirect,  punitive,  or  consequential  damages in respect of any
breach or wrongful  conduct  (whether  the claim  therefor is based in contract,
tort or duty imposed by law) in  connection  with,  arising out of or in any way
related to the transactions  contemplated  and the  relationship  established by
this  Agreement,  or  any  act,  omission,  or  event  occurring  in  connection
therewith,  and Borrower and Guarantor,  hereby waive, release, and agree not to
sue upon any such claim for any such damages, whether or not accrued and whether
or not know or suspected to exist in its favor.  Each of Borrower and  Guarantor
hereby waives any right of offset,  set off or other recoupment  against payment
of the  Obligations  to Lender,  whether now existing or arising  hereafter  and
whether any of the same arises out of any contractual  relationship  between and
among Lender, Borrower and Guarantor,  any act or conduct in respect of the loan
documents or other documents executed in connection herewith or otherwise.

     37. Binding  Effect,  Severability  and Governing Law. This Agreement shall
not be deemed to create  any right in any party  except as  provided  herein and
shall inure to the benefit of, and be binding upon,  the  successors and assigns
of Borrower, Lender and Guarantor. All of Borrower's and Guarantor's obligations
under this Agreement are absolute and unconditional, shall not be subject to any
offset or deduction whatsoever. The provisions of this Agreement are intended to
be  severable.   If  any  provision  of  this   Agreement  is  held  invalid  or
unenforceable  in whole or in part,  such  provision  will be ineffective to the
extent of such invalidity or  unenforceability  without in any manner  effecting
the validity or  enforceability  of the remaining  provisions of this Agreement.
THE  PROVISIONS  OF THIS  AGREEMENT  SHALL BE  GOVERNED  BY,  AND  CONSTRUED  IN
