     principal balance until the date paid at a rate per annum equal to the Term
     Loan Contract Rate in effect from

     2.3  Revolving Loan
          --------------

          (A)  Establishment of Revolving Loan. Subject to the provisions of
               -------------------------------
     this Agreement, and subject at all times to Bank's right in the exercise of
     its reasonable credit judgment to the creation of reserves for accrued but
     unpaid interest and otherwise as Bank deems necessary or appropriate from
     time to time, Bank shall make such loans to Borrowers (the "Revolving
     Loan") consisting of advances made by Bank against the value of Eligible
     Inventory and Eligible Accounts in such amounts as Borrowers shall request;
     provided, however, that the aggregate unpaid principal of the Revolving
     Loan outstanding at any one time shall not at any time exceed the Revolving
     Loan Borrowing Base.

          (B)  Changes in Revolving Loan Borrowing Base. Bank shall not have the
               ----------------------------------------
     right to change the advance rates set forth in the Revolving Loan Borrowing
     Base or change any other components of the Revolving Loan Borrowing Base
     except upon the occurrence and during the continuance of an Event of
     Default. Each such change shall become effective immediately for the
     purpose of calculating the amounts borrowed by Borrowers under the
     Revolving Loan.

          (C)  Payment. The Revolving Loan shall be payable in full upon the
               -------
     earlier of an Event of Default or March 1, 2002, shall bear interest as
     provided in Section 2.3(D) of this Agreement, and shall be evidenced by,
     and repayable in accordance with, the Revolving Note, but in the absence of
     the Revolving Note shall be evidenced by Bank's record of disbursements and
     repayments, which record shall be subject to Section 2.6 hereof.

          (D)  Interest on Revolving Loan. The Revolving Loan shall bear
               --------------------------
     interest on the unpaid principal balance from time to time outstanding
     until the date paid at a rate per annum equal to the Revolving Loan
     Contract Rate, such interest being payable monthly commencing September 30,
     1999 and continuing thereafter on the last day of each month so long as any
     principal balance remains outstanding. Any increase or decrease in the
     interest rate resulting from a change in the Base Rate shall become
     effective on the date of such change. Interest shall be computed on a 360-
     day year basis based upon the actual number of days elapsed.

     2.4  Unused Line Fee. Until such time as the Revolving Loan is terminated
          ---------------
as provided herein and the Revolving Loan is paid in full, Borrowers shall pay
to Bank an amount (the "Unused

                                       12
<PAGE>

Line Fee") equal to one-quarter of one percent (1/4%) of the difference between
the maximum face amount of the Revolving Loan of $10,000,000 (as of the date of
this Agreement) and the average outstanding principal balance of the Revolving
Loan during such monthly period. The Unused Line Fee shall be determined in
arrears for each month commencing on September 30, 1999 and continuing on the
last day of each month thereafter. The Unused Loan Fee shall be due and payable
commencing October 1, 1999 and continuing on the 1st day of each subsequent
month thereafter.

     2.5  Optional Charge Against Revolving Loan. To the extent Borrowers do not
          --------------------------------------
remit, when due, any payments of interest or, in the case of loans other than
the Revolving Loan, any payment of principal or any other payment required to be
made by Borrowers to Bank pursuant to the terms of any of the Credit Documents,
Bank may make such payment in the exercise of its reasonable discretion by
increasing the outstanding principal balance of the Revolving Loan to prevent
any such amount from becoming past due, but it is expressly acknowledged and
agreed by Borrowers that Bank shall be under no obligation to do so.

     2.6  Accountings.  Any accounting rendered by Bank to Borrowers shall be
          -----------
deemed correct and conclusively binding upon Borrowers unless Borrowers notify
Bank by certified mail, return receipt requested, within thirty (30) calendar
days after the date when each such accounting is received by MNC.

     2.7  All Advances to Constitute One Loan. The Revolving Loan, the Term Loan
          -----------------------------------
and all other amounts owed by Borrowers to Bank under this Agreement, whether or
not evidenced by a promissory note, shall constitute one obligation of
Borrowers, secured by Bank's lien on and security interest in all of the
Collateral. Each Borrower shall be jointly and severally liable to Bank for all
of the Obligations, regardless of whether such Obligations arise as a result of
advances made directly to Borrowers, it being stipulated and agreed that all
monies advanced by Bank hereunder inure to the benefit of Borrowers, and that
Bank is relying on the joint and several liability of Borrowers in extending
credit and otherwise making advances hereunder.

     2.8  Excess Interest.  In no contingency or event whatsoever shall the
          ---------------
interest rate charged pursuant to the terms of this Agreement exceed the highest
rate permissible under any law which a court of competent jurisdiction shall, in
a final determination, deem applicable hereto.  In the event that such a court
determines that Bank has received interest under this Agreement in excess of the
highest applicable rate, such excess interest shall be first applied to any
unpaid principal balance owed by Borrowers, and if the then remaining excess
interest is greater than the unpaid principal balance, Bank shall promptly
refund such excess interest to Borrowers.

     2.9  Revival. To the extent that Borrowers make a payment or payments to
          -------
Bank or to the extent Bank receives any payment or proceeds of the Collateral
for Borrowers' benefit, which payment or proceeds or any part thereof is
subsequently invalidated, declared to be fraudulent or preferential, set aside
and/or required to be repaid to a trustee, receiver, or any other party under
any bankruptcy act, state or federal law, common law or equitable cause, then,
to the extent of such payment or proceeds received, the Obligations or part
thereof intended to be satisfied shall be revived and shall continue in full
force and effect, as if such payment or proceeds had not been received by Bank.

                                       13
<PAGE>

     2.10  Manner of Payments.  On or before the date they become due, Borrowers
           ------------------
shall make payments to Bank in immediately available funds, even if Borrowers
contest any statements rendered by Bank; provided, however, that if any
statement is subsequently proved to be incorrect, Bank, at the option of
Borrowers, promptly shall (A) refund any overpaid amount to Borrowers, or (B)
grant a credit against amounts due for the following period in the appropriate
amount.  As to Obligations which become due and payable other than on a fixed
date by their terms or as a result of demand for payment and/or acceleration on
account of an Event of Default, Borrowers immediately shall pay to Bank such
Obligations in immediately available funds.  Whenever any payment to be made
under this Agreement including, but not limited to, any payment to be made on
any of the Notes, is stated to be due on a day which is not a banking day, such
payment may be made on the next succeeding banking day and such extension of
time in each such case shall be included in the computation of the interest
payable on such Note or such other Obligation.  Unless otherwise provided in
this Agreement, all payments or prepayments made or due under this Agreement
(including, but not limited to, payments with respect to any of the Notes) shall
be made in immediately available funds to Bank prior to 2:00 p.m., Cleveland,
Ohio, time, on the date when due.  Payments received by Bank after 2:00 p.m.,
Cleveland, Ohio, time, shall be deemed to have been made on the next following
banking day.

3.   DEFAULT INTEREST
     ----------------

     Upon and after the occurrence of an Event of Default, and during the
continuation thereof, the Obligations shall bear interest at the Default Rate,
calculated daily on a 360-day year basis, based upon the actual number of days
elapsed.

     sums, proceeds and credits of Borrowers with, and any claims of Borrowers

     4.3  Insurance.  Borrowers shall maintain and pay for insurance including,
          ---------
without limitation, insurance upon all tangible Collateral wherever located, in
storage or in transit in vehicles including goods evidenced by documents,

amounts and with such insurance companies as shall in each instance be

such policies or insurance binders thereof to Bank with satisfactory
endorsements naming Bank as an additional insured and loss payee as its interest
may appear.  In the event Borrowers deliver insurance binders to Bank, then
Borrowers, if requested by Bank, shall deliver the insurance policies relating
thereto to Bank within sixty (60) days of the date of this Agreement.  Each
policy of insurance or endorsement shall contain a provision requiring at least
ten (10) days advance written notice to Bank in the event of cancellation of the
policy for non-payment of premiums and thirty (30) days advance notice to Bank
in the event of cancellation for any other reason or any modification changing
the limits, risks insured against, or deductibles thereto and a clause that the
interest of Bank shall not be impaired or invalidated by any act or neglect of
Borrower or other owner of the Property nor by the occupation of the premises
for purposes more hazardous than are permitted by such policy.  Borrowers shall
promptly deliver to Bank upon request true copies of all reports made to
insurance companies.  Prior to the occurrence of an Event of Default, Borrowers
shall have the right and authority to make and adjust claims under such policies
of insurance.  Upon the occurrence and continuance of an Event of Default,
Borrowers hereby irrevocably make, constitute, and appoint Bank (and all
officers, employees, or agents designated by Bank) as Borrowers' true and lawful
attorney-in-fact and agent, with full power of substitution, such that Bank
shall have the right and authority to make, and adjust claims under such
policies of insurance (provided, however, that Bank shall consult with Borrowers
prior to finally making, settling, or adjusting claims under such policies of
insurance), receive, and endorse the name of Borrowers on, any check, draft,
instrument or other item of payment for the proceeds of such policies of
insurance and make all determinations and decisions with respect to such
policies of insurance or to pay any premium in whole or in part relating

Borrowers hereunder, Bank may (but shall be under no obligation to do so) at any
time or times thereafter maintain such action with respect thereto which Bank
deems advisable. All sums disbursed by Bank in connection therewith including,
without limitation, reasonable attorneys' fees, court costs, expenses and other
charges relating thereto, shall be payable, on demand, and until paid by
Borrowers to Bank, with interest thereon at the Contract Rate, shall be
additional Obligations hereunder secured by the Collateral.

maintaining, and shipping any Collateral, any and all excise, property, sales,

the Collateral, or in respect of the sale thereof, or otherwise in respect of
Borrowers' business operations which, if unpaid, could result in the imposition

          (A) Proceeds. Except for minor petty cash required in the ordinary
              --------
     course of business of Borrowers, all checks, drafts, cash and other
     proceeds realized from the sale of any Inventory or otherwise from the sale
     or other disposition of any of the other Collateral including, but not
     limited to, all proceeds realized from the collection of the Accounts or
     otherwise pursuant to any contract right, note, bill, draft, acceptance,
     chose in action and other like forms of general intangibles, and all
     remittances received by Borrowers with respect to the foregoing, shall,
     upon receipt by Borrowers, be held by Borrowers as trustee of an express
     trust for Bank's sole benefit and subject to immediate deposit (in their
     original form duly endorsed in blank) in a special account over which Bank
     has the sole right and power of withdrawal, maintained at National City
     Bank or such other financial institution acceptable to Bank (such financial
     institution and account being herein referred to as the "Depository Bank"
     and "Depository Account" respectively). The Depository Account shall be
     subject to the written agreement of the Depository Bank to waive any right
     of setoff it might otherwise claim to have against any funds in the
     Depository Account and to otherwise charge any costs relative to the
     Depository Account to Borrowers or such other account(s) as Borrowers may
     maintain with the Depository Bank, such agreement (the "Depository
     Agreement") to be in form and substance acceptable to Bank. Bank assumes no
     responsibility for any claims of accord and satisfaction or release with
     respect to funds which have been deposited in the Depository Account.

          (B) Lockbox. If at any time requested by Bank, Borrowers shall
              -------
     instruct all Account Debtors to mail their payments directly to a
     designated post office lockbox (a "Lockbox") maintained at Borrowers'
     expense, with respect to which only Bank or, should Bank so agree, a
     designated financial institution shall have the right of access and all
     payments so received shall be subject to immediate deposit into the
     Depository Account.

          (C)  Bank's Account. All funds held in the Depository Account shall be
               --------------
     subject to transfer to an account designated by the Bank (the "Bank's
     Account") as set forth in the Depository Agreement or as otherwise
     designated by Bank and the application of any such funds to the payment of
     the Obligations shall not occur until Bank's receipt of such funds in
     cleared federal funds in Bank's Account. The order and method of
     application of such payment to the Obligations shall be in the sole
     discretion of Bank. Upon receipt of notice from Borrowers regarding the
     amount of funds to be transferred from the Depository Account to the Bank's
     Account, Bank shall cause such amount of funds to be transferred to the
     Bank's Account.

          (D)  Notification of Account Debtors. Bank shall have the right upon
               -------------------------------
     an Event of Default to notify Account Debtors and other Persons indebted to
     Borrowers of Bank's interest in any such amounts payable to Borrowers and
     to instruct such Account Debtors and other Persons to remit the same
     directly to Bank. Upon the collection and deposit in Bank's Account of all
     funds arising therefrom (less any costs of collection and other charges or
     expenses incurred in connection therewith as hereinafter provided) in
     cleared federal funds, the same shall be applied to the Obligations.

     Directors of such Borrower (or, in the case of EPIC, by its partners), and

     such Borrower in accordance with their respective terms. The execution,
     delivery and performance of this Agreement and each of the other Credit
     Documents to which a Borrower is a party will not conflict with nor result
     in any breach in any of the provisions of, or constitute a default under,
     or result in the creation of any Lien (other than Permitted Liens) upon any
     Property of such Borrower under the provisions of, a Borrower's applicable
     Certificate of Incorporation, Articles of Incorporation, Partnership
     Agreement, Regulations, Bylaws, or any Material Agreement.

     or (9) other contract, agreement, understanding or arrangement which, if
     individually or in the aggregate as to Sub-paragraphs (1) through (8) above

     reasonably expected to have a Material Adverse Effect.

          (D)  Other Affiliates. Except as disclosed on Exhibit I attached to
               ----------------                         ---------

     Material Agreement, and (4) has not received any notice to the effect that
     it is not in full compliance with any of the requirements of ERISA which,
     if individually or in the aggregate as to Sub-paragraphs (1) through (4)
     above is violated, breached, or terminated for any reason, would have a
     Material Adverse Effect.

          (F)  Litigation and Administrative Proceedings. Except as disclosed on
               -----------------------------------------
     Exhibit J attached to this Agreement, there are (1) no lawsuits, actions,
     ---------
     investigations, or other proceedings pending or, to the best of Borrowers'

     Borrower may have any liability, in any court or before any governmental
     authority, arbitration board, or other tribunal, (2) no material
     grievances, disputes, or controversies outstanding with any union or other
     organization of the employees of any Borrower, or threats of work stoppage,
     strike, or pending demands for collective bargaining. Except as disclosed

        ---------
     injunctions, judgments, or decrees of any court or government agency or

     Property is bound.

          G)  Use of Proceeds. Borrowers' uses of the proceeds of any advances
              ---------------
     made by Bank to Borrowers pursuant to this Agreement are, and will continue
     to be, legal and proper business uses, duly authorized by each Borrower,
     and such uses are and will continue to be consistent with all applicable
     laws and statutes in all material respects, as in effect from time to time.
     No Borrower is engaged in the business of extending credit for the purpose
     of purchasing or carrying margin stock (within the meaning of any
     regulation of the Board of Governors of the Federal Reserve System), and no
     part of the proceeds of any loans to Borrowers will be used to purchase or
     carry (or refinance any borrowing, the proceeds of which were used to
     purchase or carry) any margin stock, or to extend credit to others for the
     purpose of purchasing or carrying margin stock.

          (H)  Intellectual Property. Each Borrower owns, possesses, or has the
               ---------------------
     right to use all the patents, patent applications, trademarks, service
     marks, copyrights, licenses, and rights with respect to the foregoing
     necessary for the conduct of its business without any known conflict with
     the rights of others. All such patents, patent applications, trademarks,
     service marks, trade names, copyrights, licenses and other similar rights
     are listed on Exhibit K attached to this Agreement.
                   ---------

<PAGE>

          (J) Title to Assets. Borrowers have good title to and ownership of
              ---------------
     all Property they purport to own, which, in the case of the Collateral, is
     free and clear of all Liens, except those in favor of Bank and any
     Permitted Liens .

          (K) Financial Statements. The Financial Statements have been prepared
              --------------------
     in accordance with GAAP and in conformity with Borrowers' normal accounting
     practices, policies, and principles which have been consistently applied
     and which fairly present the financial position of Borrowers at such date
     and the results of operations of Borrowers for such period. Except for the
     sale of stock to the Buyers pursuant to the Stock Purchase Agreement and
     the loan from MNP Corporation consisting of Subordinated Debt, there has
     not been any change in the condition, financial or otherwise, of Borrowers
     as shown on Borrowers' most recent interim Financial Statements, and no
     change in the aggregate value of machinery and equipment reflected on
     Borrowers' most recent Financial Statements, except changes in the ordinary
     course of business, none of which individually or in the aggregate will
     have a Material Adverse Effect.

          (L) Accurate and Complete Statements. Neither this Agreement nor any
              --------------------------------
     written statement made by Borrowers in connection with this Agreement
     contains any untrue statement of a material fact or omits a material fact
     necessary to make the statements contained therein or in this Agreement not
     misleading. After due inquiry by Borrowers, there is no known fact which
     Borrowers have not disclosed to Bank which has, or will have, a Material
     Adverse Effect.

          (M) Tax Returns. All Federal, state and local tax returns and other
              -----------
     reports required by law to be filed in respect of the income, business,
     properties and employees of each Borrower have been filed, and all taxes,
     assessments, fees and other governmental charges which are due and payable
     have been paid, except as otherwise permitted herein or the failure to do
     so does not and will not cause or result in a Material Adverse Effect. The
     provision for taxes on the books of each Borrower is adequate for all years
     not closed by applicable statutes and for the current fiscal year.

          (N) Securities Laws. Borrowers' execution and delivery of this
              ---------------
     Agreement and each of the other Credit Documents to which they are a party
     will not directly or indirectly violate or result in a violation of Section
     7 of the Securities Exchange Act of 1934, as amended, or any regulations
     issued pursuant thereto.

     in compliance in all material respects with, (a) the provisions, as
     amended, of the Federal Occupational Safety and Health Act, the National
     Environmental Protection Act, the Resource Conservation and Recovery Act,
     the Clean Air Act, the Clean Water Act, and all rules and regulations
     thereunder and all similar Federal, state and local laws, rules,
     regulations and government orders, and (b) all applicable Federal, state,
     and local laws, rules, regulations and government orders relating to air
     emissions, water discharge, noise emissions, solid or liquid disposal,
     hazardous waste or

     materials handling, storage or disposal, or other environmental, health or
     safety matters, and (2) to Borrower's knowledge, all real property owned or
     leased by Borrowers, and all improvements, equipment or other property
     located thereon or used therein are subject to no material contingent
     liability due to the presence of any hazardous substance, pollutant or
     contaminant (as the terms hazardous substance, pollutant or contaminant are
     defined by the Comprehensive Environmental Response, Compensation and
     Liability Act of 1980, as amended, 42 U.S.C. (S) 9601 et seq. hereinafter
                                                           ------
     "CERCLA"), (3) there are no outstanding citations, notices, or orders of

     occupant, prior tenant, prior subtenant or prior occupant or relating to
     the respective businesses, assets, property, leaseholds, or equipment of
     any Borrower under any such laws, rules, or regulations. Borrowers shall
     immediately notify Bank in the event that any Borrower receives any notice
     or claim from, or makes any notification to, any governmental entity,
     occupant, or private party with regard to any hazardous substances,
     contaminants or pollutants on, from or affecting the real property owned or
     leased by any Borrower, and all improvements, equipment or other property
     located thereon or used therein. Borrowers shall conduct and complete, at
     Borrowers' expense, all investigations, studies, sampling and testing, and
     all remedial, removal and other actions necessary to clean up and remove
     all hazardous substances, hazardous wastes, pollutants or contaminants, on,
     from or affecting the real property owned or leased by any Borrower, and
     all improvements, equipment or other property located thereon or used
     therein, to the extent required by all applicable federal, state or local
     laws, ordinances, rules, regulations, government orders and policies.
     Except as of result of negligent or wrongful actions taken by Bank's
     officers when reviewing, visiting or controlling the Principal Business
     Locations, Borrowers shall indemnify and hold Bank, its directors,
     officers, employees, agents, successors and assigns harmless from and
     against any liability, loss, damage, cost, expense, suit, threatened suit,
     action, threatened action, proceeding or threatened proceeding, directly or
     indirectly, arising out of or attributable to the use, generation, storage,

     or hazardous waste materials or hazardous substances, pollutants or
     contaminants as defined by CERCLA, or other waste-like toxic substances
     discovered at or relating to Borrower's business or other operations or the
     locations where any Borrower previously did, presently does, or in the
     future may, operate its business including, without limitation, claims of
     any Federal, state, or municipal government or quasi-governmental agency,
     or any third person, whether arising under CERCLA, the Resource
     Conservation and Recovery Act, or any other Federal, state or municipal law
     or regulation, or tort, contract or common law applicable at the time of
     closing, including but not limited to reasonable attorneys' and paralegals'
     fees and consultants' fees. Any costs or expenses incurred by Bank for
     which Borrowers are responsible or for which Borrowers have indemnified
     Bank shall be paid to Bank on demand, and failing prompt reimbursement,
     shall be added to the indebtedness secured by this Agreement and earn
     interest at the Default Rate, until paid in full.

          Any actions taken by Bank under this Section are to allow Bank to
     protect its security interest and are not intended to create any obligation
     upon Bank with respect to the operation or ownership of the real property
     owned or leased by any Borrower, or any improvements, equipment or other
     property located thereon or used therein.

     suppliers, whose purchases or supplies, individually or in the aggregate,
     are material to the business of any Borrower, and there exists no present
     condition or state of facts or circumstances which would materially affect

     sales, wholesale dispositions, or sales pursuant to one or more contracts,
     with such notice as may be required by law, in lots or in bulk, for cash or
     on credit, all as Bank, in its reasonable discretion, may deem advisable.
     Borrowers acknowledge and agree that ten (10) days written notice to
     Borrowers of any public or private sale or other disposition of Collateral
     shall be reasonable notice thereof, and such sale shall be at Borrowers'
     premises or at such other locations where the Collateral then is located,
     or as otherwise determined by Bank. Bank shall have the right to conduct
     such sales on Borrowers' premises, without charge therefor, and such sales
     may be adjourned from time to time in accordance with applicable law

     all or any part of the Collateral at public or private sale and, in lieu of
     actual payment of such purchase price, may set off the amount of such price

     Borrowers shall remain liable to Bank therefor.

     funds to the payment of the Obligations shall not occur until Bank's
     receipt of such funds in cleared federal funds in Bank's account.

     interest in any such amounts payable to any Borrower and to instruct such
     Account Debtors and other Persons to remit such amounts directly to Bank,
     and, upon collection of the same and deposit into an account for the
     benefit of Bank all funds arising therefrom (less any costs of collection
     and other charges or expenses incurred in connection therewith as
     hereinafter provided) in cleared Federal funds, the same being subject to
     application to the Obligations.

     10.4 Application of Collateral; Termination of Financing.  Upon the
          ---------------------------------------------------
occurrence and continuance of any Event of Default, Bank may also, with or
without proceeding with sale or foreclosure or demanding payment of the
Obligations, without notice, terminate Bank's further performance under this
Agreement or any other agreement or agreements between Bank and Borrowers,
without further liability or obligation by Bank, and may also, at any time,
appropriate and apply on any Obligations any and all Collateral in the
possession of Bank.  No such termination shall absolve, release or otherwise
affect the liability of Borrowers in respect of transactions had prior to such
termination, nor affect any of the Liens, rights, powers, and remedies of Bank,
but they shall, in all events, continue until all Obligations of Borrowers to
Bank are satisfied.

document referred to herein or therein or contained in any agreement
supplementary hereto or thereto or in any schedule or report given to Bank, or
contained in any other agreement between Bank and Borrowers, heretofore,
concurrently, or hereafter entered into or delivered, shall be deemed cumulative
to and not in derogation or substitution of any of the terms, covenants,
conditions, or agreements of Borrowers herein contained.

     10.6 Cross-Collateral and Cross-Default.  Each of the security interests
          ----------------------------------
and liens granted to Bank by Borrowers pursuant to the Credit Documents or
otherwise shall secure any and all of Borrowers' liabilities and obligations to
Bank under the Credit Documents including, but not limited to, Borrowers'
obligations under the Term Note and the Credit Note. It is further understood
and agreed that a default under either of the Credit Note or the Term Note, or
any of the Credit Documents shall constitute a default under each of the other
Notes and under each or the other Credit Documents. References in any of the
other Credit Documents to events or conditions constituting a default shall in
no way impair Bank's absolute and unconditional right to demand immediate
repayment of the unpaid balance of the Credit Note, notwithstanding the fact
that at the time of such demand there may not exist any event or condition
constituting a default.

     10.7 Successors and Assigns.  This Agreement shall be binding upon and
          ----------------------
inure to the benefit of Borrowers and Bank and their respective successors and
assigns; provided, however, that Borrowers shall not assign any of their rights
under the Credit Documents in whole or in part without the prior written consent
of Bank.

     10.8 Relationship of Borrowers.  The liability of each of the Borrowers
          -------------------------
under this Agreement is joint and several, and absolute and unconditional,
without regard to the liability of any other person, and shall not in any manner
be affected by reason of the partial or complete unenforceability or invalidity
of any obligations under this Agreement or other security or guaranty for any of
the loans and may be enforced without requiring Bank to first resort to any
other right, remedy or security that Bank may have, and that no Borrowers shall
have any right of subrogation, reimbursement or indemnity whatsoever, nor any
right of recourse to security for the debts and obligations of the Borrowers to
Bank unless and until all of such debts and obligations have been paid in full.
No delay in making demand on any one of Borrowers for satisfaction of its
liability hereunder shall prejudice Bank's right to enforce such satisfaction.
Bank in its reasonable discretion may, without any prejudice to its rights under
this Agreement, at any time or times (a) grant any one or more of Borrowers
whatever financial accommodations that Bank may from time to time deem
advisable, even if such Borrower might be in default in any respect under this
Agreement, (b) release any obligor or Collateral or assent to any exchange of
Collateral, if any, irrespective of the consideration, if any, received
therefor, (c) grant any waiver or consent or forbear from exercising any right,
power or privilege that Bank may have to acquire against any one or more of
Borrowers, (d) grant any other indulgence to any obligor, and (e) accept any
Collateral for, or other obligors upon, the obligations described herein.
