2.       AMOUNT AND TERMS OF REVOLVING CREDIT LOANS AND TERM LOANS.
         ---------------------------------------------------------

         2.1      Revolving Credit Loans.
                  ----------------------

                  Subject to the terms and conditions hereof, each Lender
severally agrees to make revolving credit loans (each a "Revolving Credit Loan"
and, as the context may require, collectively with all Revolving Credit Loans of
such Lender and with the Revolving Credit Loans of all other Lenders, the
"Revolving Credit Loans") to the Borrower from time to time during the Revolving
Credit Commitment Period, in an aggregate outstanding principal amount at any
one time outstanding not to exceed such Lender's Revolving Credit Commitment. At
no time shall the aggregate outstanding principal amount of the Revolving Credit
Loans of all Lenders exceed the Aggregate Revolving Credit Commitments. During
the Revolving Credit Commitment Period, the Borrower may borrow, prepay in whole
or in part and reborrow under the Revolving Credit Commitments, all in
accordance with the terms and conditions of this Agreement. Subject to the
provisions of Section 2.1.3, Revolving Credit Loans may be (a) Target Rate
Advances, (b) LIBOR Advances, or (c) a combination thereof, provided that the
aggregate outstanding principal amount of all Target Rate Advances shall not
exceed the Maximum Target Rate Advances Amount and the aggregate outstanding
principal amount of all LIBOR Advances shall not exceed the Maximum LIBOR
Advances Amount. The Borrower covenants that it will not request any borrowing
under the Revolving Credit Loans that would cause the aggregate outstanding
principal amounts of the Revolving Credit Loans to exceed the aforesaid
limitations. Any termination of the Revolving Credit Loans, whether by
expiration of the Commitment Period or as a result of the existence or
continuance of any Event of Default, shall relieve each Lender of the Lender's
obligation hereunder to lend money or to make financial accommodations to or for
the Borrower and for any of its accounts, but shall in no way release,
terminate, discharge or excuse the Borrower from its absolute duty to pay or
perform any or all of its obligations under this Agreement. The application of
the preceeding sentence is intended to apply as long as any sums remain
outstanding, due or owing under any Revolving Credit Loan.

                  2.1.1 Revolving Credit Notes. The Revolving Credit Loans made
by a Lender shall be evidenced by a Revolving Loan Note of the Borrower, the
terms and conditions of which are incorporated herein by reference. The (i) date
and amount of each Revolving Credit Loan made by a Lender, (ii) its character as
a Target Rate Advance, a LIBOR Advance, or a combination thereof, (iii) the
interest rates and periods that such rates are applicable, and (iv) each payment
and prepayment of principal and/or interest, shall be recorded by such Lender on
its books and records, but any failure of such Lender to make any such
recordation or endorsement shall not affect the obligations of the Borrower to
make payment when due of any amount owing under the Loan Documents. All
repayments shall be credited to the balances due under a Lender's Revolving
Credit Loans in accordance with the normal and customary practices of the
Lender. Interest accrued under a Lender's Revolving Credit Loans shall be
computed on the outstanding balances as reflected on the Lender's books and
records.

                  2.1.2 Procedure for Borrowing. The Borrower may borrow under
the Revolving Credit Commitments on any Business Day during the Revolving Credit
Commitment Period, provided, however, that the Borrower shall notify the Agent
(by telephone or telecopy) no later than 11:00 A.M. on the requested Borrowing
Date, specifying (A) the aggregate principal amount to be borrowed under the
Revolving Credit Commitments, (B) whether the Advance is to be a Target Rate
Advance or a LIBOR Advance (if no interest rate option is specified, then the
Borrower shall be deemed to have specified the Target Rate Advance option) and
(C) the requested Borrowing Date. Each such notice shall be irrevocable and
confirmed immediately by delivery to the Agent of a Borrowing Request. The Agent
and each Lender shall be authorized to rely upon any Borrowing Request made by
any representative of the Borrower as constituting an authorized Borrowing
Request under the Revolving Credit Loans by the Borrower. Upon receipt of each
notice of borrowing from the Borrower, the Agent shall promptly notify each
Lender thereof. Subject to the provisions of Section 2.1.3 hereof and its
receipt of the notice referred to in the preceding sentence, each Lender will
make the amount of its Revolving Credit Commitment Percentage of each borrowing
of Revolving Credit Loans available to the Borrower not later than 3:00 P.M. on
the relevant Borrowing Date requested by the Borrower, in funds immediately
available to the Borrower, by crediting an account of the Borrower maintained
with Agent for such purpose with the amount of such borrowing.

                  2.1.3 Attribution of Target Rate Advances and LIBOR Advances.
All Target Rate Advances shall be made solely by Agent in its capacity as a
Lender. All LIBOR Advances shall be made by the Lenders on a pro rata basis in
accordance with their respective LIBOR Advances Commitment Percentages. For
example, by way of illustration only, assuming the aggregate outstanding
principal amount of all Revolving Credit Loans is $10,000,000, of which
$3,000,000 constitute Target Rate Advances made solely by Agent in its capacity
as a Lender, and $7,000,000 constitute LIBOR Advances, then: (i) $3,920,000 (56
percent of $7,000,000) of the LIBOR Advances shall be made by the Agent in its
capacity as a Lender, and (ii) $3,080,000 (44 percent of $7,000,000) of the
LIBOR Advances shall be made by Fulton Bank.

                  2.1.4 Repayment. Payments of principal, interest and other
amounts due and owing under each Revolving Credit Note shall be made by the
Borrower to the Agent for the account of the respective Lender in immediately
available funds as and when provided in Section 2.4(c) with respect to interest,
and with respect to principal, as and when provided in such Revolving Credit
Note or as otherwise provided in this Agreement. The Agent will promptly remit
to each Lender its pro rata share of all Collections when received by the Agent,
together with interest at the Federal Funds Rate from the date received until
remitted, subject to the following:

                  (a) After deduction of reasonable expenses and other charges
         incurred by the Agent and reimbursable by the Borrower, Collections
         shall be applied first to the payment of all accrued but unpaid
         interest then due and payable in the order of maturity of the
         installments of such interest on a pro rata basis in relation to the
         respective aggregate amounts of accrued but unpaid interest on each
         Lender's Revolving Credit Loans constituting LIBOR Advances, and the
         balance, if any, to the payment to Agent in its capacity as a Lender of
         all accrued but unpaid interest then due and payable on all Target Rate
         Advances; and

                  (b) Second, to the repayment of all amounts of principal on a
         pro rata basis in relation to the respective outstanding principal
         balance of each Lender's Revolving Credit Loans constituting LIBOR
         Advances, and the balance, if any, to the payment to the Agent in its
         capacity as a Lender of the outstanding principal balance of Target
         Rate Advances; provided, however, that principal amounts constituting
         LIBOR Advances may be repaid only on the last day of the respective
         Interest Period applicable to such LIBOR Advance and, if repayment of a
         LIBOR Advance does not occur on the last day of the respective Interest
         Period and the Borrower has not otherwise provided the Agent with
         timely notice of the conversion of such LIBOR Advance to a Target Rate
         Advance in accordance with Section 2.1.5 of this Agreement, then such
         LIBOR Advance shall be deemed to constitute a renewed LIBOR Advance for
         a successive thirty (30) day Interest Period. Outstanding principal
         amounts constituting Target Rate Advances may be repaid at any time and
         Collections not otherwise applied to reimbursed expenses and charges,
         interest or principal amounts constituting LIBOR Advances as provided
         in the foregoing provisions of this Section 2.1.4 shall be paid to
         Agent in its capacity as a Lender as repayments of Target Rate
         Advances; and

                  (c) Notwithstanding the provisions of Sections 2.1.4(a) and
         (b) above, following the occurrence of an Event of Default and the
         acceleration by the Lenders of the amounts due under the Notes, the
         Agent shall distribute Collections, after deduction of reasonable
         expenses and other charges incurred by the Agent and reimbursable by
         the Borrower, to the Lenders on a pro rata basis in relation to the
         respective aggregate outstanding principal balance of each Lender's
         Loans to the aggregate outstanding principal balance of all Loans.

                  2.1.5 Conversions. The Borrower may elect from time to time to
convert Target Rate Advances to LIBOR Advances by giving the Agent irrevocable
notice of such election no later than 12:00 Noon, three (3) Business Days prior
to the date of such conversion, specifying the amount to be so converted. In
addition, the Borrower may elect from time to time to convert LIBOR Advances to
Target Rate Advances by giving the Agent irrevocable notice of such election no
later than 12:00 Noon, one (1) Business Day prior to such conversion, provided
that any such conversation of LIBOR Advances to Target Rate Advances shall only
be made on a Business Day and only on the last day of the Interest Period
applicable to the LIBOR Advances which are to be converted to Target Rate
Advances. The Agent shall promptly provide the Lenders with notice of any such
election. LIBOR Advances and Target Rate Advances may be converted pursuant to
this Section in whole or in part. Notwithstanding anything in this Section to
the contrary, no conversion will be effected, if the Borrower or the Agent has
knowledge that a Default or Event of Default has occurred and is continuing
either (i) at the time the Borrower notifies the Agent of its election to
convert or (ii) on the requested Conversion Date.

                  2.1.6 Duration of the Revolving Credit Loans. All sums
outstanding under the Loans shall be paid in full and the Revolving Credit Loans
shall expire on the Revolving Credit Maturity Date.

         2.2      Term Loans.
                  ----------

                  Subject to the terms and conditions hereof, Borrower shall
have the option, exercisable by written notice (each a "Term Loan Notice") to
the Agent received at any time and from time to time prior to the Revolving
Credit Maturity Date at least three (3) Business Days prior to the requested
date of conversion, to convert all or a part of the outstanding principal
balance of the Revolving Credit Loans constituting LIBOR Advances, in the amount
or amounts specified in such Term Loan Notice, to one or more term loans (each a
"Term Loan" and, as the context may require, collectively with all Term Loans of
a Lender and with the Term Loans of all other Lenders, the "Term Loans") payable
in not more than sixty (60) consecutive equal monthly installment payments of
principal, plus accrued and unpaid interest. At no time, however, shall the
aggregate original principal amount of the Term Loans of any Lender then
outstanding, together with the aggregate outstanding principal amount of the
Revolving Credit Loans of such Lender, exceed such Lender's Revolving Credit
Commitment; nor shall the aggregate original principal amount of the Term Loans
of all Lenders outstanding, together with the aggregate outstanding principal
amount of the Revolving Credit Loans of all Lender's, exceed the Aggregate
Revolving Credit Commitments. For purposes of accruing interest on the
outstanding principal balance of each and every Term Loan, each such Term Loan
shall be deemed to be comprised solely of LIBOR Advances.

                  2.2.1 Term Loan Notes. The Term Loans made by a Lender shall
be evidenced by a Term Loan Note of the Borrower, substantially in the form of
Exhibit B hereto, with appropriate insertions therein as to date, principal
amount and identity of the Lender, the terms and conditions of which shall be
incorporated herein by reference. Each such Term Loan Note will supplement and
be in addition to, but not supersede or replace, the Revolving Loan Notes.

                  2.2.2 Attribution of Term Loan Amounts. Upon receipt of a Term
Loan Notice, the Agent shall promptly determine the pro rata amount of the
principal amount specified to be converted that is to be attributable to each
Lender, such that the aggregate original principal amounts of each Lender's Term
Loans when made, together with the aggregate outstanding principal balance of
each Lender's Revolving Credit Loans at that time, shall equal in amount each
such Lender's Revolving Credit Commitment Percentage of the aggregate original
principal amounts of all Lenders Term Loans, together with the aggregate
outstanding principal balance of all Lender's Revolving Credit Loans.

                  2.2.3 Duration of Term Loans. Notwithstanding the expiration
of the Revolving Credit Commitment Period, all sums outstanding under the Term
Loans shall be paid in full in accordance with the terms and conditions of the
respective Term Loan Note.

         2.3      Prepayments of the Loans.
                  ------------------------

                  The Borrower may, at its option, prepay Target Rate Advances,
in whole or in part, without premium or penalty, at any time and from time to
time. The Borrower may pay a LIBOR Advance, in whole or in part, only at the end
of the Interest Period applicable to such LIBOR Advance.

         2.4      Interest Rate and Payment Dates.
                  -------------------------------

(a) Prior to Maturity. Except as otherwise provided in Section 2.4(b), prior to
maturity the Loans shall bear interest on the outstanding principal balances
thereof at the applicable interest rate or rates per annum set forth below.

               Advances                          Rate
               --------                          ----
        Target Rate Advance             Target Rate plus the Applicable Margin

        LIBOR Advance                   LIBOR plus the Applicable Margin

                  (b) Event of Default. After the occurrence and during the
continuance of an Event of Default, the outstanding principal balance of the
Loans and any overdue interest or other amount payable under the Loan Documents
shall bear interest at a rate per annum equal to two percent (2%) plus the rate
which would otherwise be applicable under Section 2.4(a) of this Agreement.

                  (c) General. Interest shall be calculated on the basis of a
three hundred sixty (360) days per year factor applied to the actual days on
which there exists an outstanding principal balance on a Loan. Interest shall be
payable in the case of Revolving Credit Loans in arrears on the first day of
each month during the Revolving Credit Commitment Period in respect of Target
Rate Advances, on the last day of the applicable Interest Period in respect of
LIBOR Advances, and on the Revolving Credit Maturity Date. Interest shall be
payable in the case of Term Loans in arrears on the last day of each successive
Interest Period during the term of the respective Term Loan Note and the
maturity date thereof. Any change in the interest rate on a Loan resulting from
a change in the Target Rate shall become effective as of the opening of business
on the day on which such change shall become effective. The Agent shall notify
the Borrower of the effective date and the amount of each such change in the
Target Rate, but any failure to so notify shall not in any manner affect the
obligation of the Borrower to pay interest on the Loans in the amounts and on
the dates required. Each determination of the Target Rate and LIBOR, as the case
may be, by the Agent pursuant to this Agreement shall be conclusive and binding
on the Borrower absent manifest error. At no time shall the interest rate
payable on the Loans of any Lender, together with all other amounts payable
under the Loan Documents to the extent the same are construed to constitute
interest, exceed the Highest Lawful Rate applicable to such Lender. If interest
payable to a Lender on any date would exceed the maximum amount permitted by the
Highest Lawful Rate applicable to such Lender, such interest payment shall
automatically be reduced to such maximum permitted amount, and interest for any
subsequent period, to the extent less than the maximum amount permitted for such
period by the Highest Lawful Rate, shall be increased by the unpaid amount of
such reduction. Any interest actually received for any period in excess of such
maximum allowable amount for such period shall be deemed to have been applied as
a prepayment of the Loans. The Borrower acknowledges that to the extent interest
payable on a Loan is based on the Target Rate or LIBOR, such rates are only some
of the bases for computing interest on loans made by the Lenders, and by basing
interest payable on any of such rates, the Lenders have not committed to charge,
and the Borrower has not in any way bargained for, interest based on a lower or
the lowest rate at which the Lenders may now or in the future make loans to
other borrowers.

         2.5      Use of Proceeds.
                  ---------------

                  (a) The proceeds of the Loans shall be used for working
capital and general corporate purposes including, without limitation, financing
Acquisitions (subject, however, to the conditions of Section 6.2).

                  (b) To the extent that the Agent, in its sole discretion,
determines that funds are available under the Revolving Credit Commitments, each
Lender agrees to severally issue standby letters of credit on behalf of the
Borrower upon request, subject to such terms and conditions as may be required
and approved by the Agent and the Lenders in their collective discretion,
including without limitation, the terms of the letters of credit and the terms
of repayment to be set forth in separate reimbursement agreements in form and
substance acceptable to the Agent and the Lenders. The Agent shall attribute
between or among the Lenders the amounts of letters of credit requested by the
Borrower as if such letters of credit were Term Loans to be attributed pursuant
to Section 2.2.2.

         2.6      Fees.
                  ----

                  (a) The Borrower agrees to pay to the Agent an "Unused
Facility Fee" equal to 15 basis points (0.15%) per annum (calculated on the
basis of a 360 day year for the actual days elapsed) of the unused portion of
the Maximum LIBOR Advances Amount (such unused portion being determined by
subtracting the aggregate amount of all outstanding LIBOR Advances on the
applicable date of determination from the Maximum LIBOR Advances Amount). For
purposes of calculating the unused portion of the Maximum LIBOR Advances Amount,
Letters of Credit made under the Loans and the original principal amounts of
Term Loans then outstanding shall be deemed to be used portions of the Maximum
LIBOR Advances Amount. The Unused Facility Fee shall be paid in immediately
available funds and shall be calculated on the basis of the average daily unused
portion of the Maximum LIBOR Advances Amount and shall be payable quarterly in
arrears and on the Revolving Credit Maturity Date. When received, the Agent will
promptly remit to each Lender its pro rata share of the Unused Facility Fee
based upon such Lender's Revolving Credit Commitment Percentage.

                  (b) If the Lenders are requested to issue standby letters of
credit pursuant to Section 2.5(b) of this Agreement, a separate letter of credit
fee equal in amount to one percent (1.00%) of the aggregate amounts of the
letters of credit shall be due and payable by the Borrower to the Lender upon
the issuance of the letters of credit and at each anniversary of the issuance
date occurring during the terms of the letters of credit.

                  (c) All such fees shall be the absolute property of the
Lenders upon payment. Payment of such fees shall not be considered payment of
any of the Lenders' expenses incurred in connection with the Loans. No portion
of such fees shall be refunded in the event the Borrower prepays any Loan
including, without limitation, any prepayment of the Borrower's obligations
under a letter of credit reimbursement agreement, whether in whole or in part.

         2.7      Agent's Records.
                  ---------------

                  The Agent's records with respect to the Loans, the interest
rates applicable thereto, each payment by the Borrower of principal and interest
on the Loans, and fees, expenses and any other amounts due and payable in
connection with the Loan Documents shall be presumptively correct absent
manifest error as to the amount of the Loans, the amount of principal and
interest paid by the Borrower in respect of each Loan and as to the other
information relating to the Loans, and amounts paid and payable by the Borrower
hereunder and under the Notes and other Loan Documents.

                           (iii) Worker's compensation insurance (including
                  employer's liability insurance, if requested by Agent) for all
                  employees of Borrower in such amount as is reasonably
                  satisfactory to Agent, or if such limits are established by
                  law, in such amounts;

                           (iv)  Directors  and  Officers  liability   insurance
                                 to a limit of not less than $3,000,000.

                           (v) Such other insurance, and in such amounts, as may
                  from time to time be reasonably required by Agent against the
                  same or other hazards.

                  (b) All policies of insurance required by the terms of
paragraph (a) shall contain an endorsement or agreement by the insurer that any
loss shall be payable in accordance with the terms of such policy
notwithstanding any act or negligence of Borrower which might otherwise result
in forfeiture of such insurance and the further agreement of the insurer waiving
all rights of set-off, counterclaim or deduction against Borrower.

                  (c) All policies of insurance shall be issued by companies and
in amounts reasonably satisfactory to Agent. All policies of insurance shall
have attached thereto a lender's clause in favor of Agent, and in form
reasonably satisfactory to Agent, providing that the Agent shall not be subject
to contribution, and a lender's loss payable endorsement for benefit of Agent,
all of a form satisfactory to Agent. Borrower shall furnish Agent with a signed
duplicate original policy with respect to all required insurance coverage. If
Agent consents to Borrower providing any of the required insurance through
blanket policies carried by Borrower and covering more than one location, then
Borrower shall furnish Agent with a signed certificate of insurance for each
such policy setting forth the coverage, the limits of liability, the name of the
carrier, the policy number, and the expiration date, and listing Agent as lender
or loss payee. At least twenty (20) days prior to the expiration of each such
policy, Borrower shall furnish Agent with evidence satisfactory to Agent of
payment of premium and the reissuance of a policy continuing insurance in force
as required by this Agreement. All such policies, including policies for any
amount carried in excess of the required minimum and policies not specifically
required by Agent, shall be in form satisfactory to Agent, shall be maintained
in force and effect, shall be assigned and delivered to Agent, with premiums
prepaid as collateral security for payment of the indebtedness secured hereby,
and shall contain a provision that such policies will not be canceled or
materially amended which term shall include any reduction in the scope or limits
of coverage, without at least ten (10) days prior written notice to Agent. If
the insurance, or any part thereof, shall expire, or be withdrawn, or become
void or unsafe by reason of Borrower's breach of any condition thereof, or
become void or unsafe by reason of the value or impairment of the capital of any
company in which the insurance may then be carried, or if for any reason
whatever the insurance shall be reasonably deemed by Agent to be unsatisfactory,
Borrower shall obtain new insurance reasonably satisfactory to Agent.

                  (d) In the event the Borrower fails to provide, maintain, keep
in force or deliver or furnish to Agent the policies of insurance required by
this Agreement, Agent may procure such insurance or single-interests insurance
for such risks covering Agent 's interest, and Borrower will pay all premiums
thereon promptly upon demand by Agent, and until such payment is made by
Borrower, the amount of all such premiums, together with interest thereon at the
rate specified in the Note.

                  (e) In the event of loss in excess of $100,000.00, Borrower
will give immediate notice thereof to Agent, and Agent may make proof of loss if
not made promptly by Borrower. Each insurance company concerned is hereby
authorized and directed to make payment under such insurance, including return
of unearned premiums, directly to Agent instead of to Borrower and Agent
jointly, and Borrower appoints Agent irrevocably, as Borrower's attorney-in-fact
to endorse any draft therefor. If otherwise, such policies, including all right,
title and interest of the Borrower thereunder, shall become the absolute
property of the Agent.

                  ---------------

delivered by the Borrower to the Agent pursuant to this Agreement, contains or
will contain any untrue statement of a material fact or omits or will omit to
state any material fact necessary to make the statements made not misleading.


8.       DEFAULT.
         -------

         8.1      Events of Default.
                  -----------------

                  If any one or more of the following Events of Default, each
constituting an "Event of Default," shall occur, the obligations of the Lenders
to make Advances shall cease and the entire unpaid balance of the principal of
and interest on the Loans shall immediately become due and payable in the case
of (g) or at the option of the Agent in all other cases, without notice,
presentment, protest or demand (all of which are expressly waived by the
Borrower) to the Borrower being required except as specified below:

                           (a) Failure of the  Borrower to make any payment of
                               principal  or interest in respect of any Loan
                               within 10 days after it is due; or

                           (b) The failure of the Borrower to pay the amount by
                  which the aggregate outstanding principal amount of all Loans
                  exceeds Aggregate Revolving Credit Commitments within two (2)
                  Business Days after written notice thereof shall have been
                  given by the Agent to the Borrower; or

                           (c) Failure by the Borrower or any Guarantor to
                  perform any other term, condition or covenant of this
                  Agreement, the Notes, any Loan Document or any other
                  agreement, instrument or document delivered pursuant hereto or
                  in connection herewith or therewith, which shall remain
                  unremedied for the period of thirty (30) days after written
                  notice thereof shall have been given by the Agent to the
                  Borrower; provided, however, if such failure be such that it
                  cannot be corrected within thirty (30) days, it shall not be
                  an Event of Default if, in the reasonable discretion of the
                  Agent, the Borrower is taking appropriate corrective action to
                  cure the failure and such failure will not impair the ability
                  of the Borrower to pay or perform the Borrower's obligations
                  under the Loan Documents; or

                           (d) Default is made with respect to any evidence of
                  indebtedness for borrowed money of the Borrower to any Person,
                  whether now existing or hereafter created, if as a result of
                  such default the maturity of such evidence of indebtedness is
                  accelerated, or any such indebtedness, if owed to the Agent or
                  any Lender, is not paid when due and payable; or

                           (e) A material breach of or material default by the
                  Borrower under the terms, covenants or conditions of any
                  agreements, loans or other transactions of the Borrower with
                  the Agent or any other lender, after the expiration of any
                  applicable grace or cure period; or

                           (f) Any representation or warranty made in writing to
                  the Agent and/or the Lenders in this Agreement, the Notes or
                  other Loan Documents or in connection with the making of any
                  Loan or any certificate, statement or report made in
                  compliance with this Agreement, shall have been false in any
                  material respect when made; or

                           (g) The Borrower or any Guarantor or endorser or
                  surety thereof shall make an assignment for the benefit of
                  creditors, file a petition under the Federal Bankruptcy Code
                  or any similar law, state or federal, be adjudicated insolvent
                  or bankrupt, petition or apply to any tribunal for the
                  appointment of a receiver, or trustee or a custodian for it or
                  a substantial part of its assets, or shall commence any
                  proceeding under any bankruptcy, reorganization, arrangement,
                  readjustment of debt, dissolution, or liquidation law or
                  statute of any jurisdiction, whether now or hereafter in
                  effect; or if there shall have been filed any such petition or
                  application, or any such petition or application, or any such
                  proceeding shall have been commenced against it, which remains
                  undismissed for a period of sixty (60) days or more; or the
                  Borrower or any endorser or surety by any act or omission
                  shall indicate its consent to approval of or acquiescence in
                  any such petition, application or proceeding or the
                  appointment of a receiver, or trustee or a custodian for it or
                  any substantial part of any of its properties, or shall suffer
                  any such receivership, trusteeship, or custodianship to
                  continue undischarged for a period of sixty (60) days or more;
                  or

                           (h) Any judgment against the Borrower in excess of
                  $500,000.00, or any attachment, levy or execution against any
                  of its properties in excess of $500,000.00 shall remain
                  unpaid, unstayed on appeal, undischarged, unbonded or
                  undismissed for a period of thirty (30) days or more; or

                           (i) The Borrower shall be unable, or admit its
                  inability, to meet its obligations as they come due or failure
                  of the Borrower generally to pay its debts as they become due;
                  or

                           (j) Occurrence, in Agent's sole and independent
                  discretion, reasonably exercised, of a material adverse change
                  in the business, properties or financial condition of the
                  Borrower, or an event or condition which, in Agent's sole and
                  independent discretion reasonably exercised would be expected
                  to result in such a material adverse change.

         8.2      Remedies.
                  --------

                  In the event of the occurrence and during the continuation of
any Event of Default, the Agent may, but shall not be required to (i) proceed to
apply to the payment of the Loans the balance to the credit of any account or
accounts maintained with any Lender by the Borrower and all property of Borrower
now or at any time in any Lender's possession in any capacity whatsoever
(set-off) and (ii) the obligation of any Lender to make loans or otherwise
extend credit to the Borrower shall immediately terminate. The Agent may
exercise any other right or remedy provided pursuant to the Loan Documents and
hereby granted or allowed to it by law, and each and every right and remedy
provided pursuant to the Loan Documents and hereby granted to the Agent or any
Lender or allowed to one or the other by law shall be cumulative and not
exclusive the one of the other, and may be exercised by the Agent from time to
time and as often as may be necessary. The Agent shall have at any time, in its
discretion, the right to enforce collection and payment by appropriate action or
proceedings, and the net amounts received therefrom, after deduction of all
costs and expenses incurred in connection therewith, shall be applied on account
of the Loan and any other indebtedness or liabilities of the Borrower aforesaid,
all without notice to the Borrower. The Agent shall not be required to marshall
any security or guarantees or to resort to the same in any particular order.


9.       THE AGENT.
         ---------

         9.1      Appointment.
                  -----------

                  Each Lender hereby irrevocably designates and appoints
Allfirst Bank, as the Agent of such Lender under the Loan Documents and each
such Lender hereby irrevocably authorizes Allfirst Bank, as the Agent for such
Lender, to take such action on its behalf under the provisions of the Loan
Documents and to exercise such powers and perform such duties as are expressly
delegated to the Agent by the terms of the Loan Documents, together with such
other powers as are reasonably incidental thereto. Notwithstanding any provision
to the contrary elsewhere in any Loan Document, the Agent shall not have any
duties or responsibilities, except those expressly set forth therein, or any
fiduciary relationship with any Lender, and no implied (or express) covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into the Loan Documents or otherwise exist against the Agent, whether arising
under principles of agency or otherwise under applicable law. The term "Agent"
is used merely as a matter of market custom, and is intended to create or
reflect only an administrative relationship among independent contracting
parties.

         9.2      Administration.

                  In the course of its administration of the Loans and the Loan
Documents, the Agent may, without notice to or consent of the Lenders, in its
sole discretion except as otherwise provided below, exercise or refrain from
exercising any powers or rights vested in the Agent under the Loan Documents or
any document relating thereto or which the Agent may be entitled to assert at
law or in equity or otherwise enforce or refrain from enforcing the obligations
of the Borrower. Notwithstanding the foregoing, the Agent will not, without the
consent of all of the Lenders: (i) consent to the reduction of (A) any amount
due and owing by the Borrower pursuant to the Loan Documents, (B) any rate of
interest payable under the Loan Documents, or (C) the rate at which fees accrue
under the Loan Documents; (ii) increase the amounts of or reinstate any Loan
other than such reinstatement as is provided in the Loan Documents; (iii) extend
the maturity date of any Loan; (iv) postpone the due date for any payment to be
made by Borrower pursuant to the Loan Documents; (vi) consent to or waive any
failure by the Borrower to pay money to the Lenders if such failure would
otherwise constitute an Event of Default under the Loan Documents; (vii) waive
any Event of Default under the Loan Documents; (viii) waive compliance with any
of the terms and conditions of the Loan Documents; (ix) give or withhold
consents to or approvals of any action or failure to act by the Borrower; (x)
change the definition of "Required Lenders"; (xi) release any Guarantor from
Liability under its respective Guaranty and Suretyship Agreement; or (xii) amend
this Section 9.2 or any other provision of this Agreement providing for consent
or other action by the Required Lenders; provided, however, that items (viii)
and (ix) shall require the consent of the Required Lenders only. Notwithstanding
any other provision to the contrary, Agent agrees to promptly provide to each
Lender a copy of each report, certificate or other notice or request received
from or on behalf of Borrower or any Guarantor pursuant to Sections 5.1, 5.2
and/or 5.3 of this Agreement or otherwise, as well as a copy of each notice the
Agent provides to the Borrower or any Guarantor pursuant to this Agreement or
any other Loan Document.

         9.3      Delegation of Duties.
                  --------------------

                  The Agent may execute any of its duties under the Loan
Documents by or through agents or attorneys-in-fact and shall be entitled to
rely upon the advice of counsel concerning all matters pertaining to such
duties. The Agent shall not be responsible for the negligence or misconduct of
any such agent or attorney-in-fact in the absence of the Agent's own gross
negligence or willful misconduct.


<PAGE>



         9.4      Exculpatory Provisions.
                  ----------------------

                  Neither the Agent nor any of its officers, directors,
employees, agents, attorneys-in-fact or affiliates shall be (i) liable for any
action lawfully taken or omitted to be taken by it or such Person under or in
connection with the Loan Documents (except for its own gross negligence or
willful misconduct), or (ii) responsible in any manner to any of the Lenders for
any recitals, statements, representations or warranties made by the Borrower or
any Guarantor or any officer thereof contained in the Loan Documents or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Agent under or in connection with, the Loan Documents or for
the value, validity, effectiveness, genuineness, enforceability or sufficiency
of any of the Loan Documents or for any failure of the Borrower or any other
Person to perform its obligations thereunder. The Agent shall not be under any
obligation to any Lender to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, the Loan
Documents, or to inspect the properties, books or records of any Loan Party. The
Agent shall not be under any liability or responsibility whatsoever, as Agent,
to the Borrower or any other Person as a consequence of any failure or delay in
performance, or any breach, by any Lender of any of its obligations under any of
the Loan Documents.

         9.5      Reliance by Agent.
                  -----------------

                  The Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, opinion, letter, cablegram, telegram, telecopy, telex or
teletype message, statement, order or other document or conversation believed by
it to be genuine and correct and to have been signed, sent or made by the proper
Person or Persons and upon advice and statements of legal counsel (including,
without limitation, counsel to the Borrower), independent accountants and other
experts selected by the Agent. The Agent may treat each Lender, or the Person
designated in the last notice filed with it under this Section, as the holder of
all of the interests of such Lender in its Loans and in its Notes until written
notice of transfer, signed by such Lender (or the Person designated in the last
notice filed with the Agent) and by the Person designated in such written notice
of transfer, in form and substance satisfactory to the Agent, shall have been
filed with the Agent. The Agent shall not be under any duty to examine or pass
upon the validity, effectiveness or genuineness of the Loan Documents or any
instrument, document or communication furnished pursuant thereto or in
connection therewith, and the Agent shall be entitled to assume that the same
are valid, effective and genuine, have been signed or sent by the proper parties
and are what they purport to be. The Agent shall be fully justified in failing
or refusing to take any action under the Loan Documents unless it shall first
receive such advice or concurrence of the Required Lenders as it deems
appropriate and, if it so requests, it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action. The
Agent shall in all cases be fully protected in acting, or in refraining from
acting, under the Loan Documents in accordance with a request or direction of
the Required Lenders, and such request or direction and any action taken or
failure to act pursuant thereto shall be binding upon all the Lenders and all
future holders of the Notes. Where this Agreement expressly permits or prohibits
an action unless the Required Lenders otherwise determine, the Agent shall, and
in all other instances, the Agent may, but shall not be required to, initiate
any solicitation for the consent or a vote of the Lenders.

         9.6      Notice of Default.
                  -----------------

                  The Agent shall not be deemed to have knowledge or notice of
the occurrence of any Event of Default, except with respect to default in the
payment of principal, interest and fees required to be paid to the Agent for the
account of the Lenders, unless the Agent has received written notice thereof
from a Lender or the Borrower referring to this Agreement, describing such Event
of Default and stating that such notice is a "notice of default." In the event
that the Agent receives such a notice, the Agent shall promptly give notice
thereof to the Lenders. The Agent shall take such action with respect to such
Default or Event of Default as shall be reasonably directed by the Required
Lenders, provided, however, that unless and until the Agent shall have received
such directions, the Agent may (but shall not be obligated to) take such action,
or refrain from taking such action, with respect to such Default or Event of
Default as it shall deem to be in the best interests of the Lenders.

         9.7      Non-Reliance on Agent and Other Lenders.
                  ---------------------------------------

                  Each Lender expressly acknowledges that neither the Agent nor
any of its respective officers, directors, employees, agents, attorneys-in-fact
or affiliates ("Agent-Related Persons") has made any representations or
warranties to it and that no act by the Agent or any Agent-Related Person
hereinafter, including any review of the affairs of the Borrower or any other
Person, shall be deemed to constitute any representation or warranty by the
Agent to any Lender. Each Lender represents to the Agent that it has,
independently and without reliance upon the Agent or any other Lender, and based
on such documents and information as it has deemed appropriate, made its own
evaluation of and investigation into the business, operations, property,
financial and other condition and creditworthiness of the Borrower and the
Guarantors and made its own decision to enter into this Agreement. Each Lender
also represents that it will, independently and without reliance upon the Agent
or any other Lender, and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit analysis,
evaluations and decisions in taking or not taking action under any Loan
Document, and to make such investigation as it deems necessary to inform itself
as to the business, operations, property, financial and other condition and
creditworthiness of the Borrower and the Guarantors. Except for notices, reports
and other documents expressly required to be furnished to the Lenders by the
Agent hereunder, the Agent shall not have any duty or responsibility to provide
any Lender with any credit or other information concerning the business,
operations, property, financial and other condition or creditworthiness of the
Borrower and the Guarantors which may come into the possession of the Agent or
any of its officers, directors, employees, agents, attorneys-in-fact or
affiliates.

         9.8      Indemnification.
                  ---------------

                  Each Lender agrees to indemnify and reimburse the Agent in its
capacity as such (to the extent not promptly reimbursed by the Borrower and
without limiting the obligation of the Borrower or any Guarantor) upon demand,
pro rata according to its Revolving Credit Commitment, from and against any and
all liabilities, obligations, claims, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind whatsoever
(including, without limitation, any amounts paid to the Lenders (through the
Agent) by the Borrower pursuant to the terms of the Loan Documents, that are
subsequently rescinded or avoided, or must otherwise be restored or returned)
which may at any time (including, without limitation, at any time following the
payment of the Notes) be imposed on, incurred by or asserted against the Agent
in any way relating to or arising out of the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, the Loan Documents or any other documents
contemplated by or referred to therein or the transactions contemplated thereby
or any action taken or omitted to be taken by the Agent under or in connection
with any of the foregoing to the extent the Agent is not reimbursed for such
expenses by or on behalf of the Borrower; provided, however, that no Lender
shall be liable for the payment of any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements to the extent resulting solely from the gross negligence or
willful misconduct of the Agent. The agreements in this Section shall survive
the payment of all amounts payable under the Loan Documents, the termination of
the Aggregate Revolving Credit Commitments and the resignation of the Agent.

         9.9      Agent in Its Individual Capacity.
                  --------------------------------

                  Allfirst Bank and its respective affiliates may make loans to,
accept deposits from, issue letters of credit for the account of, and generally
engage in any kind of business with, the Borrower and/or any Guarantor as though
Allfirst Bank was not Agent hereunder and without notice to or consent of any
Lender. The Lenders acknowledge that pursuant to such activities, Allfirst Bank
or its affiliates may receive information regarding the Borrower or a Guarantor
(including information that may be subject to confidentiality obligations in
favor of the Borrower or such Guarantor) and acknowledge that the Agent shall be
under no obligation to provide such information to them. With respect to
Allfirst Bank's Revolving Credit Commitment and the Notes issued to Allfirst
Bank hereunder, Allfirst Bank shall have the same rights and powers under the
Loan Documents as any Lender and may exercise the same as though it was not the
Agent, and the terms "Lender" and "Lenders" shall in each case include Allfirst
Bank in its individual capacity.

         9.10     Successor Agent.
                  ---------------

                  If at any time the Agent deems it advisable, in its sole
discretion, it may submit to each of the Lenders a written notice of its
resignation as Agent under this Agreement, such resignation to be effective upon
the earlier of (i) the written acceptance of the duties of the Agent under the
Loan Documents by a successor Agent and (ii) on the 30th day after the date of
such notice. Upon any such resignation, the Required Lenders shall have the
right to appoint from among the Lenders a successor Agent. If no successor Agent
shall have been so appointed by the Required Lenders and accepted such
appointment in writing within 30 days after the retiring Agent's giving of
notice of resignation, then the retiring Agent may, on behalf of the Lenders,
appoint a successor Agent, which successor Agent shall be a commercial bank
organized under the laws of the United States of America or any State thereof.
Upon the acceptance of any appointment as Agent hereunder by a successor Agent,
such successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent's rights, powers, privileges and duties as Agent under the Loan Documents
shall be terminated. The Borrower and the Lenders shall execute such documents
as shall be necessary to effect such appointment. After any retiring Agent's
resignation hereunder as Agent, the provisions of the Loan Documents shall inure
to its benefit as to any actions taken or omitted to be taken by it while it was
Agent under the Loan Documents. If at any time hereunder there shall not be a
duly appointed and acting Agent, the Borrower agrees to make each payment due
under the Loan Documents directly to the Lenders entitled thereto during such
time.

                  No modification or waiver of any provision of this Agreement,
the Notes, the other Loan Documents or other instruments or consent to any
departure by the Borrower from any of the terms or conditions thereof, shall in
any event be effective unless it shall be in writing and signed by the Agent
(and, but only to the extent specifically required by Section 9.2, each Lender)
and the Borrower, and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. No notice to or demand on
the Borrower in any case shall, of itself, entitle the Borrower to any other or
further notice or demand in similar or other circumstances.

         10.3     Rights Cumulative.
                  -----------------

                  Each and every right granted to the Agent or a Lender
hereunder or under any other document delivered hereunder or in connection
herewith, or allowed one or the other by law or equity, shall be cumulative and
may be exercised from time to time. No failure on the part of the Agent to
exercise, and no delay in exercising, any right shall operate as a waiver
thereof, nor shall any single or partial exercise of any right preclude any
other or future exercise thereof or the exercise of any other right.

         10.4     Construction and Severability.
                  -----------------------------

                  This Agreement, the Notes and the other Loan Documents and the
rights and obligations of the parties shall be construed and interpreted in
accordance with the laws of the Commonwealth of Pennsylvania. The provisions of
this Agreement are severable and if any clause or provision shall be held
invalid or unenforceable in whole or in part in any jurisdiction, then such
invalidity or unenforceability shall affect only such clause or provision, or
part thereof, in such jurisdiction and shall not in any manner affect such
clause or provision in any other jurisdiction, or any other clause or provision
in this Agreement in any jurisdiction.

         10.5     Conflict of Documents.
                  ---------------------

                  The provisions of this Agreement are in addition to, and not
in limitation of, the provisions of the Notes and the other Loan Documents. In
the event of conflict between the provisions of this Agreement and the
provisions of the Notes or any Loan Document, the provisions of this Agreement
shall prevail.

         10.8     Binding Effect.
                  --------------

                  This Agreement and any other documents and instruments
delivered or required to be delivered pursuant hereto shall inure to the benefit
of and shall be binding upon the parties hereto and their heirs, executors,
administrators, personal representatives, successors and permitted assigns of
the parties hereto. The Borrower may not assign its rights or obligations
hereunder without the prior written consent of Agent and all of the Lenders.

         10.9     Participations and Assignments.
                  ------------------------------

                  (a) Each Lender with the prior written consent of the Agent
and the Borrower (which consent of the Borrower shall not be unreasonably
withheld and shall not be required upon the occurrence and during the
continuance of an Event of Default), shall have the right to assign all or any
part of such Lender's Loans, Revolving Credit Commitment and Notes, on a pro
rata basis, to any other lender; provided, however, notwithstanding the
foregoing, that any such assignment by Fulton Bank and each Fulton Affiliate (as
hereinafter defined) shall be permitted without such consent if made to a Fulton
Affiliate. For the purposes of Section 10.9, the term "Fulton Affiliate" shall
mean any commercial bank organized under the laws of the United States of
America or any State thereof that is, directly or indirectly, wholly-owned by
the entity that is Fulton Bank's "ultimate parent entity" as such term is
defined in 16 CFR ss.801.1. For each assignment, the parties to such assignment
shall execute and deliver to the Agent for its acceptance and recording an
Assignment and Acceptance Agreement. Upon such execution, delivery, acceptance
and recording by the Agent, from and after the effective date specified in such
Assignment and Acceptance Agreement, the assignee thereunder shall be a party
hereto and, to the extent provided in such Assignment and Acceptance Agreement,
the assignor Lender thereunder shall be released from its obligations under the
Loan Documents. The Borrower agrees upon written request of the Agent and at the
Borrower's expense to execute and deliver (1) to such assignee, Notes, dated the
effective date of such Assignment and Acceptance Agreement, in an aggregate
principal amount equal to the Loans assigned to, and Revolving Credit Commitment
assumed by, such assignee and (2) to such assignor Lender, Notes, dated the
effective date of such Assignment and Acceptance Agreement, in an aggregate
principal amount equal to the balance of such assignor Lender's Loans and
Revolving Credit Commitment, if any, and each assignor Lender shall cancel and
return to the Borrower its existing Notes. Upon any such assignment, the
applicable Revolving Credit Commitment and Revolving Credit Commitment
Percentages set forth in Exhibit A shall be adjusted accordingly by the Agent
and a new Exhibit A shall be distributed by the Agent to the Borrower and each
Lender.

                  (b) Each Lender may grant participations in all or any part of
its Loans, its Notes and its Revolving Credit Commitment to one or more lenders,
provided that (i) such Lender's obligations under the Loan Documents shall
remain unchanged, (ii) such Lender shall remain solely responsible to the other
parties to the Loan Documents for the performance of such obligations, (iii) the
Borrower, the Agent and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under the Loan Documents, (iv) no sub-participations shall be
permitted and (v) the voting rights of any holder of any participation shall be
limited to decisions that only do any of the following: (A) subject the
participant to any additional obligation, (B) reduce the principal of, or
interest on the Notes or any fees or other amounts payable hereunder to the
extent such participant has an interest therein, (C) postpone any date fixed for
the payment of principal of, or interest on, the Notes or any fees or other
amounts payable hereunder to the extent such participant has an interest
therein; provided, however, notwithstanding the foregoing, that any such
participation granted by Fulton Bank and each Fulton Affiliate shall require the
prior written consent of the Agent if made to any lender other than a Fulton
Affiliate.

         10.10    Indemnification by the Borrower.
                  -------------------------------

                  In addition to all amounts payable hereunder, the Borrower
shall protect, indemnify, and save harmless the Agent, each Lender and their
respective officers, employees and agents (collectively, the "Indemnitees")
against and from any and all liabilities, suits, actions, claims, demands,
losses, expenses and costs of every kind and nature incurred by, or asserted or
imposed against any Indemnitee by reason of (a) any accident, injury (including
death) or damage to any person or property, however caused (other than the
negligence or willful misconduct of such Indemnitee), resulting from, connected
with or growing out of any act of commission or omission of the Borrower, or any
officers, employees, agents, assignees, contractors or subcontractors of the
Borrower, or (b) any untrue statement by the Borrower or any of its officers,
employees or agents of a material fact or any omission by the Borrower or any of
its officers, employees or agents to state a material fact necessary in order to
make any statements made, in light of the circumstances under which they were
made, not misleading and made in connection with the Loans and the transactions
contemplated by this Agreement; and, in any such case, regardless of whether
such liabilities, suits, actions, claims, demands, damages, losses, expenses and
costs be against, or be suffered or sustained by, any Indemnitee, or be against,
or be suffered or sustained by, legal entities, officers, agents, or other
persons to whom an Indemnitee may become liable therefor. The Borrower may, and
if so requested by the Indemnitee shall, undertake to defend, at its sole cost
and expense, any and all suits, actions and proceedings brought against such
Indemnitee in connection with any of the matters indemnified against in this
Section. The Agent and each Lender agree to give the Borrower timely notice of
and shall forward to the Borrower every demand, notice, summons or other process
received with respect to any claim or legal proceeding within the purview
hereof, but the failure to give such notice shall not affect an Indemnitee's
rights to indemnification hereunder unless the failure to give notice shall have
deprived the Borrower of a reasonable opportunity to contest any such matter. If
the indemnification provided for herein is held by a court to be unavailable or
is insufficient to hold harmless the Indemnitees in respect of any losses,
claims, damages or liabilities (or actions in respect thereof), then the
Borrower shall contribute to the amount paid or payable by the Indemnitees as a
result of the losses, claims, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect the relative fault of
the Borrower on the one hand and the Indemnitees on the other hand, as well as
any other relevant equitable considerations. The provisions of this Section
shall survive the expiration of the Revolving Credit Commitment Period, the
repayment, satisfaction or discharge of the Loans, and the Resignation of the
Agent or replacement of any Lender.

         10.11    Integration.
                  -----------

                  All Exhibits to a Loan Document shall be deemed to be a part
thereof. The Loan Documents embody the entire agreement and understanding among
the Borrower, the Agent, the Lenders and the other parties thereto with respect
to the subject matter thereof and supersede all prior agreements and
understandings among the Borrower, the Agent, the Lenders and the other parties
with respect to the subject matter thereof including, without limitation, those
portions of that certain Credit Agreement dated February 16, 1999 by and between
The First National Bank of Maryland, a division of FMB Bank (a predecessor to
Allfirst Bank), as the same has been amended and supplemented, and the related
Loan Documents, specifically relating to the Revolving Loan as defined therein;
provided, however, that the provisions of said prior Credit Agreement and the
related Loan Documents, to the extent the same apply to the Mortgage Loan as
defined therein, shall continue in full force and effect.

         10.12    Waiver of Trial by Jury.
                  -----------------------

                  THE AGENT, EACH LENDER AND THE BORROWER HEREBY KNOWINGLY,
VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHT EITHER OF THEM MAY HAVE TO A TRIAL
BY JURY IN RESPECT OF ANY LITIGATION ARISING OUT OF, UNDER OR IN CONNECTION WITH
THE LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREIN. FURTHER, THE
BORROWER HEREBY CERTIFIES THAT NO REPRESENTATIVE OR AGENT OF THE AGENT OR ANY
LENDER, OR COUNSEL THERETO, HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE
AGENT OR ANY LENDER WOULD NOT, IN THE EVENT OF SUCH LITIGATION, SEEK TO ENFORCE
THIS WAIVER OF RIGHT TO JURY TRIAL PROVISION. THE BORROWER ACKNOWLEDGES THAT THE
AGENT AND THE LENDERS HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, INTER
ALIA, THE PROVISIONS OF THIS SECTION.

         10.13    Jurisdiction and Venue.

                  The Borrower hereby irrevocably consents to the exclusive
jurisdiction of any state or federal court for the county or judicial district
where the Agent's office indicated in Section 10.6 of this Agreement is located,
and consents that all service of process be sent by nationally recognized
overnight courier service directed to the Borrower at the Borrower's address set
forth herein and service so made will be deemed to be completed on the business
day after deposit with such courier; provided that nothing contained in this
Agreement will prevent the Agent or any Lender from bringing any action,
enforcing any award or judgment or exercising any rights against the Borrower
individually, against any security or against any property of the Borrower
within any other country, state or other foreign or domestic jurisdiction. The
Agent and the Borrower agree that the venue provided above is the most


<PAGE>


convenient forum for both the Agent and the Borrower. The Borrower waives any
objection to venue and any objection based on a more convenient forum in any
action instituted under this Agreement.

         The Borrower acknowledges that it has read and understands all the
provisions of this Agreement, including Waiver of Trial by Jury, and has been
advised by counsel as necessary or appropriate.

         IN WITNESS WHEREOF, the parties hereto, intending to be legally bound,
have caused this Agreement to be duly executed on its respective behalf on the
date first set forth above.
