as successor by merger to CORESTATES BANK, N.A. (the "Lender").

                                    RECITALS

             1.     The Lender and the Borrower are parties to a Second
Amended and Restated Credit Agreement dated as of May 15, 2000, which sets
forth the terms and conditions of a credit facility for advances under a line
of credit for working capital, and for the issuance of letters of credit for
the account of the Borrower.

             2.     The debt under the credit facility is evidenced by a Third
Amended and Restated Revolving Credit Note dated May 15, 2000, in the face
amount of $9,200,000.

             3.     Payment of the Third Amended and Restated Revolving Credit

Credit Loans") to the Borrower from time to time during the Revolving Credit
Commitment Period in an aggregate principal amount at any one time outstanding
not to exceed the Revolving Credit Maximum Amount (the "Revolving Credit
Commitment"). During the Revolving Credit Commitment Period, the Borrower may

                                      15

part, and reborrowing, all in accordance with and subject to the terms and
conditions of this Agreement, including Subsection 2.10.

with, the Fourth Amended and Restated Revolving Credit Note dated December 15,
2000 (as amended, modified, extended, renewed, supplemented or replaced from

interest on the unpaid principal amount thereof from time to time outstanding
at the applicable interest rate per annum determined as provided in
Subsections 2.13 and 2.14. Interest on the Revolving Credit Note shall be
payable on the dates specified in Subsection 2.13(f).

funds are transferred between the Operating Account and the Revolving Credit
Loan for credit or debit to the Revolving Credit Loan.

                    (b)    If the Lender determines that the Lender's Sweep
Plus product shall no longer be used for Revolving Credit Loans, the procedure
for borrowing set forth in this Subsection 2.3(b) shall apply. The Lender may
withdraw the Sweep Plus product at any time in the sole and absolute
discretion of the Lender. The Borrower may borrow under the Revolving Credit
Commitment during the Revolving Credit Commitment Period on any Business Day,
provided that the Borrower shall give the Lender irrevocable notice (which
must be received by the Lender prior to 11:00 a.m., McLean, Virginia time) two
Business Days prior to the requested Borrowing Date, specifying (i) the amount
to be borrowed, and (ii) the requested Borrowing Date. Each borrowing pursuant
to the Revolving Credit Commitment shall be in an aggregate principal amount
of One Thousand Dollars ($1,000.00) or a whole multiple thereof. The proceeds
of all Revolving Credit Loans will be made available to the Borrower by the
Lender by transfer of such proceeds in immediately available funds to a
deposit account of the Borrower at the Lender designated for such purpose.

                    (c)    Availability under the Revolving Credit Facility
shall be subject to the delivery to the Lender of a Borrowing Base Certificate
and updated information pertaining to all RICs in the Lender's possession.
Without limiting in any way the provisions of Section 5.2, in no event shall
the Lender be obligated to make a Revolving Credit Loan if the Revolving
Credit Loan would cause the total principal amount of Revolving Credit Loans
made and outstanding to exceed the Revolving Credit Maximum Amount. Even if
the total principal amount of Revolving Credit Loans outstanding shall at any
time and for any reason exceed the

                                      16
<PAGE>   22

Revolving Credit Maximum Amount, the Borrower shall nonetheless be liable for
the entire principal amount of Revolving Credit Loans outstanding, with
interest and other charges, as provided in this Agreement. If the total
principal amount of Revolving Credit Loans shall at any time exceed the
Revolving Credit Maximum Amount, the Borrower shall immediately pay to the
Lender upon demand the amount of such excess, with interest as provided in
this Agreement.

             2.4    Facility Fee. For the months of December, 2000 and January
through August, 2001 the Borrower shall pay to the Lender a Revolving Credit
Facility Fee of 1% per annum of the Revolving Credit Facility Ceiling.
Beginning on September 1, 2001, the Borrower shall pay to the Lender a
Revolving Credit Facility Fee of 2% per annum of the Revolving Credit Facility
Ceiling. Each Revolving Credit Facility Fee shall be payable on the last day
of each month, and shall be calculated based on the highest level of the
Revolving Credit Facility Ceiling during the month.

             2.5    Default Fees. For each Default of which the Lender gives
notice to the Borrower, the Borrower shall pay on demand to the Lender a
$5,000 default fee. For each Default that becomes an Event of Default, the
Borrower shall pay on demand to the Lender a $10,000 default fee. For each
Event of Default for which no cure period is applicable, the Borrower shall
pay to the Lender and immediately be liable for a $15,000 default fee.

             2.6    Payment at Revolving Credit Termination Date. On the
Revolving Credit Termination Date, the Borrower shall pay to the Lender in
full the Revolving Credit Loan Balance, together with all accrued and unpaid
interest thereon.

             2.7    Conversion of Revolving Credit Loans to Convertible Term

             2.10   Principal Payments.

                    (a)    Unless otherwise determined by the Lender, the
terms of the Lender's Sweep Plus Product shall control the manner in which
funds are transferred between the Operating Account and the Revolving Credit
Loan for credit or debit to the Revolving Credit Loan.

                    (b)    If the Lender determines that the Lender's Sweep
Plus Product shall no longer be used for Revolving Credit Loans, the procedure
for borrowing set forth in this Subsection 2.10(b) shall apply. The Borrower
may at any time from time to time pay the principal of Revolving Credit Loans
in whole or in part, upon irrevocable notice to the Lender at least one (1)
Business Day in advance, specifying the date and amount of payment. If any
such payment notice is given by the Borrower, the payment amount specified in
such notice shall be due and payable on the date specified therein.

             2.13   Interest Rates and Payment Dates.

                    (a)    Revolving Credit Loans shall bear interest for the
period from and after the Closing Date on the unpaid principal amount at a
rate per annum equal to the Prime Rate plus 2%.

                    (b)    (intentionally deleted)

                    (c)    (intentionally deleted)

                    (d)    If an Event of Default shall occur, all Revolving
Credit Loans shall, at the Lender's option, bear interest on the unpaid
principal amount thereof at a rate per annum equal to the Prime Rate plus five
percent (5%) per annum.

                    (e)    Except to the extent prohibited by applicable law,
any judgment or order of any Governmental Authority entered for payment of
principal or any other amounts bearing interest under this Agreement shall
bear interest at the rates and calculated in the manner applicable under this
Agreement to such amounts.

                    (f)    Interest shall be payable in arrears on each
Interest Payment Date, and the Borrower authorizes the Lender to debit the
Operating Account for all such interest payments.

             2.14   Computation of Interest and Fees. (a) Facility fees under
Subsection 2.4 and interest in respect of the Loans shall be calculated on the
basis of a 360 day year for the actual days elapsed (including the first but
excluding the last day of the relevant period). Any change in the interest
rate on Loans resulting from a change in the Prime Rate (as a result of a
change in the Prime Rate) shall become effective as of the opening of business
on the day on which such change in the Prime Rate shall become effective.

                    (b)    Each determination of an interest rate by the
Lender pursuant to any provision of this Agreement shall be conclusive and
binding on the Borrower in the absence of manifest error.

             2.15   Inability to Determine Interest Rate.  (intentionally

             2.16   Payments. All payments (including prepayments) to be made

whether on account of principal, interest, fees, expenses or other amounts,
shall be made without deduction, setoff or

                                      18
<PAGE>   24

counterclaim and shall be made at the Lender's office set forth in Subsection
9.3, in lawful money of the United States of America and in immediately
available funds. If any payment hereunder becomes due and payable on a day
other than a Business Day, such payment shall be extended to the next
succeeding Business Day, and, with respect to payments of principal, interest
thereon shall be payable during such extension. The Lender may charge and
deduct from any deposit account of the Borrower at the Lender any amounts
credited to such account and apply the same to pay principal, interest,
service charges, fees (including Default Fees and Facility Fees), expenses or
any other sums or charges due and unpaid under this Agreement, the Note or any
other Credit Documents. The Lender may, in addition to all other rights and
remedies available to it, set off against any Obligations due and unpaid any
sums or property owing to the Borrower by the Lender or held or controlled by
the Lender for the Borrower. The Borrower confirms the Lender's right to a
banker's lien and setoff, and nothing in this Agreement or any other Credit
Document shall be deemed to replace, supercede, limit, waive or prohibit the
Lender's right of banker's lien and setoff.

             2.17   Illegality.  (intentionally deleted).

             2.18   Requirements of Law.

                    (a)    If any generally applicable Requirement of Law or
any change therein or in the interpretation or application thereof or
compliance by the Lender with any request or directive (whether or not having
the force of law) from any central bank or other Governmental Authority
arising from and after the Closing Date:

                           (i)    does or shall subject the Lender to any
additional tax of any kind whatsoever with respect to this Agreement or the
Note, or change the basis of taxation of payments to the Lender of principal,
fees, interest or any other amount payable hereunder (except for changes in
the rate of tax on the overall net income of the Lender);

                           (ii)   does or shall impose, modify or hold
applicable any reserve, special deposit, assessment, capital adequacy,
compulsory loan or similar requirement against assets held by, or deposits or
other liabilities in or for the account of, advances or loans by, or other
credit extended by, or any other acquisition of funds by, any office of the
Lender; or

                            (iii) does or shall impose on the Lender any other
condition;

and the result of any of the foregoing is to increase the cost to the Lender,
by any amount which the Lender deems to be material, of making, renewing or
maintaining advances or extensions of credit or to reduce any amount
receivable hereunder, then, in any such case, the Borrower shall promptly pay
the Lender upon demand any additional amounts necessary to compensate the
Lender for such additional cost or reduced amount receivable reasonably
allocable to this Agreement, together with interest on such additional amounts
from the date demand is made until payment in full thereof at the rate
applicable to Revolving Credit Loans. If the Lender becomes entitled to claim
any additional amounts pursuant to this Subsection, it shall promptly notify
the Borrower of the event by reason of which it has become so entitled. A
certificate as to

                                      19
<PAGE>   25

any additional amounts payable pursuant to the foregoing sentence submitted by
the Lender to the Borrower shall show the means by which such additional
amounts have been calculated and shall be conclusive in the absence of
manifest error. This covenant shall survive the termination of this Agreement
and payment of the Note for a period of 1 year.

                    (b)    If the Lender shall have determined that the
adoption from and after the Closing Date of any generally applicable law,
rule, regulation or guideline regarding capital adequacy, or any change
therein from and after the Closing Date or in the interpretation or
application thereof or compliance by the Lender or any corporation controlling
the Lender with any request or directive regarding capital adequacy (whether
or not having the force of law) from any central bank or Governmental
Authority, including, without limitation, the issuance of any final rule,
regulation or guideline, does or shall have the effect of reducing the rate of
return on the Lender's or such corporation's capital as a consequence of its
obligations hereunder to a level below that which the Lender or such
corporation could have achieved but for such adoption, change or compliance
(taking into consideration the Lender's or such corporation's policies with
respect to capital adequacy) by an amount deemed by the Lender to be material,
then from time to time, within 2 Business Days after submission by the Lender
to the Borrower of a written request therefor showing the means by which such
additional amounts have been calculated and stating in reasonable detail the
reasons therefor, the Borrower shall pay to the Lender such additional amount
or amounts reasonably allocable to this Agreement as will compensate the
Lender for such reduction.

             2.19   Taxes.

                    (a)    All payments made by the Borrower under this
Agreement shall be made free and clear of, and without reduction or
withholding for or on account of, any present or future income, stamp or other
taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now
or hereafter imposed, levied, collected, withheld or assessed by any
Governmental Authority excluding, in the case of the Lender, net income and
franchise taxes imposed on the Lender by the jurisdiction under the laws of
which the Lender is organized or any political subdivision or taxing authority
thereof or therein (all such non-excluded taxes, levies, imposts, deductions,
charges or withholdings being hereinafter called "Taxes"). If any Taxes are
required to be withheld from any amounts payable to the Lender hereunder,
under the Note or under any other Credit Document, the amounts so payable to
the Lender shall be increased to the extent necessary to yield to the Lender
(after payment of all Taxes, including those payable on additional amounts
paid pursuant to this Subsection) interest or other amounts payable hereunder
at the rates or in the amounts specified in this Agreement, the Note or any
other Credit Document. If the Borrower fails to pay any Taxes when due to the
appropriate taxing authority, the Borrower shall indemnify the Lender for any
incremental taxes, interest or penalties that may become payable by the Lender
as a result of any such failure.

                    (b)    The agreements in this Subsection shall survive the
termination of this Agreement and the payment of the Note and all other
amounts payable hereunder and under the other Credit Documents for a period of
1 year.

             2.21   Certain Calculations  (intentionally deleted).

             2.22   Revolving Credit Cash Collateral Account. On December 28,
2000, the Borrower shall deposit $400,000 into the Revolving Credit Cash
Collateral Account. On January 31, 2001, and on February 28, 2001, the
Borrower shall deposit $400,000 into the Revolving Credit Cash Collateral
Account, or the amount necessary to make the amount on deposit in the
Revolving Credit Cash Collateral Account equal 110% of the Revolving Credit
Facility Ceiling, whichever is less. On March 31, 2001, the Borrower shall
deposit into the Revolving Credit Cash Collateral Account the amount necessary
to make the amount on deposit in the account equal to 110% of the Revolving
Credit Facility Ceiling. In addition, if the DOED releases the Borrower from
HCM2 restrictions and thereby releases funds and allows processing of student
loans now pending HCM2 approval, the Borrower shall deposit all such released
funds into the Revolving Credit Cash Collateral Account until the balance
equals 110% of the Revolving Credit Facility Ceiling.

             SECTION 3. LETTERS OF CREDIT

             3.1    Letter of Credit Commitment. Subject to the terms and
conditions hereof, the Lender agrees to issue for the account of the Borrower
standby letters of credit for such purposes, in such amounts, for the benefit
of such Persons and subject to such terms and conditions as may be acceptable
to the Lender in its discretion (individually, as amended, modified, extended,
renewed, supplemented or replaced from time to time, a "Letter of Credit,"
and, collectively, the "Letters of Credit"), from and including the date of
this Agreement to but not including the Revolving Credit Termination Date (the
"L/C Commitment"); provided that the L/C Exposure shall not on any date exceed
$2,138,628.50, less the amount of any Existing L/Cs which are canceled (which
shall occur when the original Letter of Credit is surrendered by the
beneficiary to the Lender with a statement from the beneficiary confirming
that the Letter of Credit is no longer in effect). No Letter of Credit
(including any renewal or extension thereof, whether or not automatic) shall
have an expiry date which is later than the date which is one year after the
date of issuance, renewal or extension of such Letter of Credit; and provided
further that, no Letter of Credit (including any renewal or extension thereof,
whether or not automatic) shall have an expiry date which is later than
September 5, 2002; and provided further that the Lender shall be under no
obligation to issue a new Letter of Credit unless all existing Letters of
Credit shall be cash secured to the extent of 110% of their face amount, and
the new Letter of Credit to be issued would be cash secured to the extent of
110% of its face amount.

             3.2    Procedure for Issuance and Renewal of Letters of Credit.

                    (a)    The Borrower may request the Lender to issue a
Letter of Credit by delivering to the Lender at its office specified in
Subsection 9.3 (i) such L/C Agreements as the Lender may require, completed to
the satisfaction of the Lender, (ii) the proposed form of such Letter of
Credit (which shall comply with the applicable requirements set forth herein)
and (iii) such other certificates and documents and information as the Lender
may reasonably request.

                                      21
<PAGE>   27

                    (b)    The Borrower may request the extension or renewal
of a Letter of Credit issued hereunder which is not automatically renewed in
accordance with the terms contained therein, by giving written notice to the
Lender at least forty-five calendar days prior to the then current expiry date
of such Letter of Credit (provided that the Lender may accommodate notices on
shorter notice in its sole discretion).

             3.3    Reimbursement of the Lender. In the case of each drawing
paid under any Letter of Credit, the Lender shall promptly notify the Borrower
of such drawing and of the amount thereof, and the Borrower (i) shall
reimburse the Lender for the amount of such drawing not later than the close
of business on the first Business Day following the day on which the Borrower
receives notice of such drawing, and (ii) shall pay (A) all charges and
expenses relating to such drawing as may be payable in accordance with
Subsection 3.4 or the applicable L/C Agreements and (B) interest at the rate
specified in Subsection 3.5 on the amount of such drawing for the period
commencing on and including the date of payment of such drawing and ending on
and including the date the Borrower reimburses the Lender for such drawing.
The Borrower authorizes the Lender to debit the L/C Cash Collateral Account
for the amount of any reimbursement or payment obligation under this
Subsection 3.3. Notwithstanding any other provision of this Agreement, the
payment by the Lender of each drawing under a Letter of Credit shall be deemed
to constitute an irrevocable notice of borrowing by the Borrower under
Subsection 2.3 and, at any time after such request, the Lender is irrevocably
authorized by the Borrower to, and the Lender may, make Revolving Credit Loans
to the Borrower in an amount equal to the amount of such payment and any
charges, expenses or interest referred to in the foregoing clauses (A) and
(B), notwithstanding any limitations set forth in Subsection 2.3, and apply
the proceeds of such Revolving Credit Loans in payment of the Borrower's L/C
Reimbursement Obligations and other obligations in connection with such
payment.

             3.4    Commissions, Fees and Charges.

                    (a)    In the case of each issuance, renewal or extension
of any Letter of Credit, the Borrower agrees to pay to the Lender (i) an
issuance fee equal to Five Hundred Dollars ($500.00), and (ii) a commission on
the face amount of such Letter of Credit calculated at the L/C Commission
Rate, based upon a year of 360 days and payable for the actual number of days
in the original term, the renewal term or the extended term of such Letter of
Credit, provided that the amount of such commission shall not be less than Two
Hundred Fifty Dollars ($250.00) per quarter annum (or a portion thereof). The
Borrower shall not be entitled to receive a refund or rebate of any such fees
or commissions in the event of early termination of a Letter of Credit.

                    (b)    Payment of the fees set forth in this Subsection
shall be a condition to the issuance of each Letter of Credit; provided that,
in the case of any automatic renewal or automatic extension of any Letter of
Credit in accordance with the terms thereof, the Borrower shall pay such fees
before the date of such automatic renewal or automatic extension.

                                      22
<PAGE>   28

                    (c)    In addition to the fees referred to above in this
Subsection, the Borrower agrees to pay or reimburse the Lender for such normal
and customary fees, costs and expenses as are incurred or charged by the
Lender or any correspondents of the Lender in issuing, effecting payment
under, maintaining or administering any Letter of Credit (including, without
limitation, amendment fees, correspondent bank fees, reissuance costs and
cancellation fees) upon notice and invoice by the Lender to the Borrower of
such costs and expenses.

             3.5    Interest on Amounts Disbursed under Letters of Credit. The
Borrower agrees to pay to the Lender interest on any and all amounts drawn
under any Letter of Credit until reimbursed in full at a fluctuating rate per
annum equal to the rate applicable to Revolving Credit Loans. Interest accrued
hereunder shall be payable on demand. All payments by the Borrower to the
Lender shall be made in lawful currency of the United States and in
immediately available funds without setoff or counterclaim to the Lender at
its office specified in Subsection 9.3.

             3.6    Computation of Interest and Fees; Payment not on Business
Days.

                    (a)    Any change in any interest rate under this Section
3 resulting from a change in the Prime Rate shall become effective as of the
opening of business on the day on which such change in the Prime Rate becomes
effective.

                    (b)    If any payment under this Section 3 becomes due and
payable on a day which is not a Business Day, the maturity thereof shall be
extended to the next succeeding Business Day, and, in the case of any amount
drawn under a Letter of Credit, interest thereon shall be payable at the then
applicable rate during such extension.

             3.7    Increased Costs. If any generally applicable law or
regulation or other Requirement of Law, or any change in the interpretation or
application thereof by any Governmental Authority charged with the
administration thereof, shall either (a) impose, modify, assess or deem
applicable any reserve, special deposit, assessment, capital adequacy or
similar requirement against letters of credit issued by the Lender or (b)
impose on the Lender any other condition regarding any Letter of Credit, and
the result of any event referred to in clauses (a) or (b) above shall be to
increase the cost to the Lender of issuing or maintaining such Letter of
Credit, then, within ten (10) Business Days after delivery to the Borrower by
the Lender of a certificate as to the fact and amount of such increased cost,
the Borrower shall pay to the Lender such additional amounts reasonably
allocable to this Agreement which shall be sufficient to compensate the Lender
for such increased cost, together with interest on each such amount from the
date such certificate is received by the Borrower until payment in full
thereof at the rate provided in Subsection 3.5. A certificate as to the fact
and amount of such increased cost incurred by the Lender as a result of any
event mentioned in clauses (a) or (b) above, submitted by the Lender to the
Borrower, shall show the means by which such additional amounts have been
calculated and shall be conclusive, absent manifest error. This covenant shall
survive the termination of this Agreement and payment of the Note for a period
of one (1) year.

                                      23

             3.8    Nature of Obligations; Indemnities.

                    (a)    The obligations of the Borrower under this Section
3 shall be absolute and unconditional under any and all circumstances and
irrespective of any setoff, counterclaim or defense to payment which the
Borrower may have or have had against the Lender, any correspondents of the
Lender or any beneficiary of a Letter of Credit; provided that this provision
shall not be deemed a waiver by the Borrower of the assertion of any
compulsory counterclaim. The Borrower assumes all risks of the acts or
omissions of the users of the Letters of Credit and all risks of the misuse of
the Letters of Credit. None of the Lender or any of its correspondents shall
be responsible:

                           (i)    for the form, validity, sufficiency,
accuracy, genuineness or legal effect of any draft drawn under any Letter of
Credit or any document specified in any applications for any of the Letters of
Credit, even if it should in fact prove to be in any or all respects invalid,
insufficient, inaccurate, fraudulent, or forged and even if the Borrower shall
have notified the Lender or any of its correspondents thereof;

                           (ii)   for the validity or sufficiency of any
instrument transferring or assigning or purporting to transfer or assign any
of the Letters of Credit or any of the rights or benefits thereunder or
proceeds thereof in whole or in part, which may prove to be invalid or
ineffective for any reason;

                           (iii)  for failure of any draft to bear any
reference or adequate reference to any of the Letters of Credit, or failure of
any Person to note the amount of any draft on the reverse of any of the
Letters of Credit or to surrender or to take up any of the Letters of Credit
or to send forward any such document apart from drafts as required by the
terms of any of the Letters of Credit, each of which provisions, if contained
in a Letter of Credit itself, it is agreed, may be waived by the Lender;

                           (iv)   for errors, omissions, interruptions or
delays in transmission or delivery of any messages, by mail, cable, telegraph,
telex or otherwise, whether or not in cipher;

                           (v)    for any error, neglect, default, suspension
or insolvency of any correspondents of the Lender;

                           (vi)   for errors in translation or for errors in
interpretation of technical terms;

                           (vii)  for any loss or delay, in the transmission
or otherwise, of any such document or draft or of proceeds thereof;

                           (viii) for any failure of any draft or document
presented under a Letter of Credit to comply with, or for any determination by
the Lender whether the same complies with, the terms of such Letter of Credit;
or

                                      24
<PAGE>   30

                           (ix)   for any other circumstances whatsoever in
making or failing to make payment under a Letter of Credit; provided that the
Borrower shall have a claim against the Lender, and the Lender shall be liable
to the Borrower, to the extent, but only to the extent, of any direct, as
opposed to consequential, damages suffered by the Borrower which the Borrower
proves were caused by the Lender's willful misconduct or gross negligence.
None of the above shall affect, impair or prevent the vesting of any of the
rights or powers of the Lender. The Lender shall have the right to transmit
the terms of the Letter of Credit as requested without translating them.

                    (b)    In furtherance and extension and not in limitation
of the specific provisions in this Section 3, (i) any action taken or omitted
by the Lender or by any of its correspondents under or in connection with any
of the Letters of Credit, if taken or omitted in good faith or pursuant to
instructions of the Borrower, shall be binding upon the Borrower and shall not
put the Lender or any of its correspondents under any resulting liability to
the Borrower and (ii) the Lender may accept documents that appear on their
face to be in order, without responsibility for further investigation,
regardless of any notice or information to the contrary.

                    (c)    The Borrower hereby agrees at all times to protect,
indemnify and save harmless the Lender and its correspondents from and against
any and all claims, actions, suits and other legal proceedings, and from and
against any and all losses, claims, demands, liabilities, damages, costs,
charges, reasonable counsel fees and other expenses which they or any of them
may, at any time, sustain or incur by reason of or in consequence of or
arising out of the issuance of any of the Letters of Credit unless caused by
the Lender's gross negligence or willful misconduct; it being the intention of
the parties that this Agreement shall be construed and applied to protect and
indemnify the Lender and its correspondents against any and all risks involved
in the issuance of all of the Letters of Credit unless caused by the Lender's
gross negligence or willful misconduct, all of which risks, whether or not
foreseeable, being hereby assumed by the Borrower, including, without
limitation, any and all risks of all acts by any Governmental Authority,
domestic or foreign. The Lender and its correspondents shall not in any way be
liable for any failure by any of them or any other Person to pay a draft drawn
under any of the Letters of Credit as a result of any acts, whether rightful
or wrongful, of any Governmental Authority, or any other cause not readily
within their control or the control of their respective correspondents, agents
or sub-agents. Without limiting the generality of the foregoing, the Borrower
shall reimburse the Lender and its correspondents, and shall pay and indemnify
the Lender and its correspondents, against payment of, out-of-pocket costs and
expenses, withholding taxes, liabilities and damages, including, without
limitation, attorneys' fees, incurred or sustained by any of them in
connection with any of the Letters of Credit or by reason of any such failure
to pay. Also, without limiting the generality of the foregoing, the Borrower
shall be responsible for, and shall reimburse the Lender upon demand for, any
and all commissions, fees and other charges paid or payable by the Lender to
any bank which shall be an advising bank or a beneficiary of a Letter of
Credit which shall, in reliance thereon, have issued its own letter of credit

represents and warrants to the Lender that:

             4.1    Financial Condition. The following financial statements of
the Borrower have been delivered to the Lender:

                    (a)    the audited consolidated statement of income and
retained earnings of the Borrower for the fiscal year of the Borrower ended
January 31, 2000, and the audited consolidated statement of cash flows of the
Borrower for such fiscal year, and the audited consolidated balance sheet of
the Borrower as at the end of such fiscal year; and

                    (b)    the statement of income and retained earnings of
the Borrower for the quarterly accounting period of the Borrower ended October
31, 2000, and for the current fiscal year of the Borrower through the end of
such quarterly accounting period, and the statement of cash flows of the
Borrower for such quarterly accounting period and for the current fiscal year
of the Borrower through the end of such quarterly accounting period, and the
balance sheet of the Borrower as at the end of such quarterly accounting
period.

The documents listed in this Subsection 4.1 have been prepared in conformity
with GAAP consistently applied, are correct and complete in all material
respects and present fairly the financial position of the Borrower as of the
dates of such statements and the results of operations of the Borrower for the
periods covered by such statements.

             4.2    No Change. As of the Closing Date, there shall not have
been any material adverse change in the business, operations, property or
financial or other condition of the Borrower from the date of the most recent
financial statements referred to in Subsection 4.1 hereof.

             4.3    Organization and Good Standing; Compliance with Law. The
Borrower (a) is a corporation duly organized, validly existing and in good
standing under the laws of the

                                      26
<PAGE>   32

State of Delaware, (b) has the legal right to own and operate its property, to
lease the property it operates as lessee and to conduct the business in which
it is currently engaged, (c) is duly qualified to conduct business and is in
good standing under the laws of the State of Delaware, the Commonwealth of
Virginia, the Commonwealth of Pennsylvania, the State of Texas, the State of
Illinois, the State of California and each other jurisdiction in which such
qualification is required by applicable law, and (d) is in compliance with all
Requirements of Law except to the extent that the failure to comply therewith
could not, in the aggregate, reasonably be expected to have a Material Adverse
Effect.

             4.4    Authorization; Enforceable Obligations. The Borrower has
the legal right to make, deliver and perform the Credit Documents to which it
is a party and to borrow hereunder and has taken all necessary action to
authorize the borrowings on the terms and conditions of this Agreement and the
Note and to authorize the execution, delivery and performance of the Credit
Documents to which it is a party. No consent or authorization of, filing with
or other act by or in respect of any Governmental Authority is required in
connection with the borrowings hereunder or with the execution, delivery,
performance, validity or enforceability of the Credit Documents to which the
Borrower is a party except those which have been obtained or performed and are
in full force and effect. This Agreement has been, and each other Credit
Document to which it is a party will be, duly executed and delivered on behalf
of the Borrower. This Agreement constitutes, and each other Credit Document to
which it is a party when executed and delivered will constitute, a legal,
valid and binding obligation of the Borrower enforceable against the Borrower
in accordance with its terms, except as enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting the enforcement of creditors' rights generally and by general
equitable principles (whether enforcement is sought by proceedings in equity
or at law).

             4.5    No Legal Bar. The execution, delivery and performance of
the Credit Documents to which the Borrower is a party, the borrowings
hereunder and the use of the proceeds thereof, will not violate any
Requirement of Law or any Contractual Obligation of the Borrower, and will not
result in, or require, the creation or imposition of any Lien on any of its
properties or revenues pursuant to any Requirement of Law or Contractual
Obligation, except as contemplated by the Credit Documents.

             4.6    No Material Litigation; Labor Matters. Except as set forth
in Schedule 4.6, no litigation, proceeding or, to the Borrower's actual
knowledge, investigation of or before any arbitrator or Governmental Authority
is pending or, to the knowledge of the Borrower, threatened by or against the
Borrower or against any of its properties or revenues (a) with respect to any
of the Credit Documents or any of the transactions contemplated hereby or
thereby, or (b) which, if determined adversely to the Borrower, could
reasonably be expected to have a Material Adverse Effect. There are no
strikes, work stoppages, grievance proceedings or other controversies pending
or, to the knowledge and belief of the Borrower, imminent or threatened
between the Borrower and any employees of the Borrower or between the Borrower
and any union or other collective bargaining unit representing employees of
the Borrower which could reasonably be expected to have a Material Adverse
Effect.

             4.8    Ownership of Property; Liens. The Borrower has good title
to all of its property, and none of its property is subject to any Lien,

             4.9    Business Premises. The Borrower does not own, lease,

discharged, spilled, emitted or disposed of on any Obligor Use Property by the
Borrower or under circumstances as a result of which the Borrower would be
liable or financially responsible for damages or the cost of remediation or
clean-up;

                    (b)    there is no existing Hazardous Substance
Contamination of any Obligor Use Property which was caused by the Borrower or

the cost of removal, remediation or cleanup; and

             4.12   Solvency. On the Closing Date and after giving effect to
the borrowings hereunder on such date and to all other Indebtedness being
incurred on such date in connection therewith (a) the sum of the assets, at a

                                      28
<PAGE>   34

exceed the Borrower's debts as reflected in its most current balance sheet,
(b) the present fair saleable value of the assets of the Borrower will, as of
such date, be greater than the amount that will be required to pay the
Borrower's liability on its debts as such debts become absolute and matured,
and (c) the Borrower will have, as of such date, sufficient capital with which
to conduct its business. For purposes of this Subsection, "debt" means
"liability on a claim" and "claim" means any (i) right to payment, whether or
not such right is reduced to judgment, liquidated, unliquidated, fixed,
contingent, matured, unmatured, disputed, undisputed, legal, equitable,
secured or unsecured, or (ii) right to an equitable remedy for breach of
performance if such breach gives rise to a right to payment, whether or not
such right to an equitable remedy is reduced to judgment, fixed, contingent,
matured, unmatured, disputed, undisputed, secured or unsecured.

             4.13   Taxes. The Borrower has filed or caused to be filed all
tax returns which are required to be filed by the Borrower, and the Borrower
has paid all taxes shown to be due and payable on said returns or on any
assessments made against it or any of its property and all other taxes, fees
or other charges imposed on it or any of its property by any Governmental
Authority (other than any taxes the amount or validity of which are currently
being contested in good faith by appropriate proceedings and with respect to
which reserves in conformity with GAAP have been provided on the books of the
Borrower); and no tax lien has been filed and, to the knowledge of the
Borrower, no claim is being asserted with respect to any such tax, fee or
other charge.

                    (a)    No part of the proceeds of any of the Loans will be
used for "purchasing" or "carrying" any "margin stock" within the respective
meanings of each of the quoted terms under Regulation U of the Board of
Governors of the Federal Reserve System as now and from time to time hereafter
in effect or for any purpose which violates the provisions of any Regulations
of the Board of Governors; and

                    (b)    if requested by the Lender, the Borrower will
furnish to the Lender a statement to the foregoing effect in conformity with
the requirements of FR Form U-I referred to in Regulation U.

                    (a)    With respect to each employee pension benefit plan,

Requirements of Law;

the Borrower, nor, to the actual knowledge of any director or officer of the

"party in interest" (as defined in Section 3(14) of ERISA), or a "disqualified
person" (as defined in Section 4975(e)(2) of the Code), has acted or failed to
act with respect to the Retirement Plan in any manner which constitutes a
breach of fiduciary responsibility within the meaning of Title I, Subtitle B,
Part 4 of ERISA, a prohibited transaction within the meaning of Section 4975
of the Code or Sections 406 through 408 of ERISA, or any other material
violation of ERISA;

been funded in accordance with the minimum funding standards described in
Section 412 of the Code and Title I, Subtitle B, Part 3 of ERISA (for which
purpose there is no "accumulated funding deficiency," whether or not waived),
and in accordance with principles that are actuarially sound for such
Retirement Plan.

paid; and

                           (iv)   if the Retirement Plan were terminated, the
termination would qualify under the standard termination procedure, as
described in Section 4041(b) of ERISA (and Part 2617 of the PBGC regulations),
without payment of any additional contributions by the Borrower or any
Subsidiary of the Borrower.

and reports with respect to the Borrower (other than projections) furnished to
the Lender by the Borrower or on behalf of the Borrower were, at the time the
same were so furnished, complete and correct in all material respects, or have
been subsequently supplemented by other information and reports to the extent
necessary to give the Lender a fair and accurate knowledge of the subject
matter in all material respects. All projections with respect to the Borrower
so furnished by the Borrower, as supplemented, were prepared and presented in
good faith, it being recognized by the Lender that such projections as to
future events are not to be viewed as facts and that actual results during the
period or periods covered by any such projections may differ from the
projected results. No fact is known to the Borrower which materially and
adversely affects or in the future may (so far as the Borrower can reasonably
foresee) materially and adversely affect the business, assets or liabilities,
financial condition, results of operations or business prospects of the
Borrower which has not been set forth in the financial statements referred to
in Subsection 4.1 or in such information and reports disclosed in writing to
the Lender prior to the date hereof. No document furnished or statement made
in writing to the Lender by the Borrower in connection with the negotiation,
preparation or execution of this Agreement contains any untrue statement of a
material fact, or omits to state any such material fact necessary in order to
make the statements contained therein not misleading, in either case which has
not been corrected, supplemented or remedied by subsequent documents furnished
or statements made in writing to the Lender.

             4.18   Purpose of Loans. The Borrower shall use the proceeds of

Expenditures, or (c) to make payments to the Lender required by this
Agreement.

             4.19   CLCQ and Delta College. (intentionally deleted)

             4.20   No Intent to File Bankruptcy. The Borrower does not have
any present intent (i) to file any voluntary petition in bankruptcy under any
chapter of the Bankruptcy Code or to have any involuntary petition in
bankruptcy filed against it under any chapter of the Bankruptcy Code or (ii)
in any manner directly or indirectly to seek relief, protection,
reorganization, liquidation, dissolution, or similar relief for debtors under
any federal, state or local law, or in equity, or (iii) in any manner directly
or indirectly to cause any part of the

                                      32
<PAGE>   38

Collateral to be the subject of any bankruptcy or insolvency proceedings or
the property of any bankruptcy or insolvency estate; and the Borrower
acknowledges and agrees that the filing of any such petition or any action
taken by the Borrower to cause the filing of any such petition would be in bad
faith, contrary to the purposes of the Bankruptcy Code, and solely for
purposes of delaying, inhibiting, or interfering with the exercise by the
Lender of its rights and remedies with respect to the Collateral and the
Credit Facilities.

             SECTION 9. MISCELLANEOUS

             9.1    Amendments and Waivers. Neither this Agreement, the Note or
any other Credit Document, nor any terms hereof or thereof may be amended,
modified, extended, renewed, supplemented or replaced except in accordance with
the provisions of this Subsection. The Lender and the Borrower may from time to
time enter into written amendments, modifications, extensions, renewals,
supplements or replacements for the purpose of amending, modifying, extending,
renewing, supplementing or replacing any provisions of this Agreement or the
other Credit Documents or changing in any manner the rights of the parties
hereunder or thereunder or waiving, on such terms and conditions as the Lender
may specify in such instrument, any of the requirements of this Agreement or the
other Credit Documents or any Default or Event of Default and its consequences.
In the case of any waiver, the Borrower and the Lender shall be restored to
their former positions and rights hereunder and under the Note, and any Default
or Event of Default waived shall be deemed to be cured; but no such waiver shall
extend to any subsequent or other Default or Event of Default, or impair any
right consequent thereupon.

             9.2    More Restrictive Provisions. If the Borrower enters into or
becomes bound by any credit agreement, purchase agreement or other agreement,
document or instrument (but not including any statutory requirement or any
requirement imposed by regulatory authorities), or any amendment, modification,
supplement or restatement thereof, which requires the Borrower to comply with
any financial covenants which are in addition to or more restrictive (the
"Additional/More Restrictive Provisions") than the covenants contained in
Section 7, this Agreement shall be deemed to be automatically and immediately
amended to include such Additional/More Restrictive Provisions. If such credit
agreement, purchase agreement or other agreement or document which contains the
Additional/More Restrictive Provisions, or the Additional/More Restrictive
Provisions, are terminated and of no further force or effect, then any amendment
of this Agreement effected as a result of the provisions of this Subsection 9.2
shall be of no further force or effect and this Agreement shall be deemed to be
automatically and immediately amended to conform to the terms of this Agreement
prior to the amendment of this Agreement effected pursuant to this Subsection
9.2 as a result of such Additional/More Restrictive Provisions. If, after an
amendment of this Agreement effected pursuant to this Subsection 9.2 as a result
of Additional/More Restrictive Provisions, such Additional/More Restrictive
Provisions shall be amended or modified and the result of such amendment or
modification is to cause some or all of such Additional/More Restrictive
Provisions to be more restrictive or less restrictive, but in any event more
restrictive than the financial covenants contained in Section 7 prior to such
amendment of this Agreement, then this Agreement shall be deemed to be
automatically and immediately amended to conform to such Additional/More
Restrictive Provisions, as so amended or modified. Upon request of the Lender at
any time or from time to time, the Borrower shall promptly execute and deliver
to the Lender such amendments of this Agreement, and such other agreements,
instruments and documents, as the Lender may request to further memorialize
amendments of this Agreement pursuant to this Subsection 9.2.

failure of any party hereto to provide a copy of any notice, request or demand
to Shaw Pittman or Piper Marbury Rudnick & Wolfe LLP as provided above shall

             9.4    No Waiver; Cumulative Remedies. No failure to exercise and
no delay in exercising, on the part of the Lender, any right, remedy, power or
privilege hereunder or under the Credit Documents, shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder or thereunder preclude any other or further exercise thereof
or the exercise of any other right, remedy, power or privilege. The rights,

                                       54
<PAGE>   60

remedies, powers and privileges herein provided or provided in the other Credit
Documents are cumulative and not exclusive of any rights, remedies, powers and
privileges provided by law.

             9.5    Survival of Representations and Warranties. All
representations and warranties made hereunder, in the other Credit Documents and
in any document, certificate or statement delivered pursuant hereto or in
connection herewith shall survive the execution and delivery of this Agreement
and the Note.

             9.6    Payment of Expenses and Taxes. The Borrower agrees (a) to
pay or reimburse the Lender for all of its costs and expenses incurred in
connection with the development, preparation and execution of, and any
administration, amendment, modification, extension, renewal, supplement or
replacement of, this Agreement, the other Credit Documents and any other
documents prepared in connection herewith or therewith, and the consummation of
the transactions contemplated hereby and thereby, including, without limitation,
the fees and disbursements of counsel to the Lender, (b) to pay or reimburse the
Lender for all of its costs and expenses incurred in connection with the legal
interpretation, enforcement or preservation of any rights under this Agreement,
the other Credit Documents and any such other documents, including, without
limitation, the fees and disbursements of counsel to the Lender, (c) to pay,
indemnify and hold the Lender harmless from, any and all recording and filing
fees and any and all liabilities with respect to, or resulting from any delay in
paying, stamp, excise and other taxes, if any, which may be payable or
determined to be payable in connection with the execution and delivery of, or
consummation of any of the transactions contemplated by, or any amendment,
modification, extension, renewal, supplement or replacement of, or any waiver or
consent under or in respect of, this Agreement, the other Credit Documents and
any such other documents, and (d) to pay, indemnify and hold the Lender harmless
from, any and all other liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever with respect to the execution, delivery, enforcement,
performance and administration of this Agreement, the other Credit Documents and
any such other documents (all of the foregoing, collectively, the "indemnified
liabilities"); provided that the Borrower shall have no obligation hereunder to
the Lender with respect to indemnified liabilities arising from (i) the gross
negligence or willful misconduct of the Lender, or (ii) legal proceedings
commenced against the Lender by any security holder or creditor thereof arising
out of and based upon rights afforded any such security holder or creditor
solely in its capacity as such. The agreements in this Subsection shall survive
the termination of this Agreement and payment of the Note for a period of 2
years. The Borrower authorizes the Lender to debit from the Operating Account
all such payments or reimbursements which the Borrower is required to make under
this Subsection 9.6.

             9.7    Further Assurances, Power of Attorney. The Borrower agrees
promptly to do, make, execute and deliver all such additional and further acts,
things, deeds, assurances, instruments and documents as the Lender may
reasonably request to vest in and assure to the Lender its rights under this
Agreement or any of the other Credit Documents. Borrower hereby appoints Lender
and its designees as attorney-in-fact of Borrower, irrevocably and with power of
substitution, with authority to execute and

                                       55
<PAGE>   61

deliver from time to time, in the name and stead of the Borrower, all documents
which Borrower is required to, but has failed or refused to, execute and deliver
to Lender pursuant to this Agreement or any of the Credit Documents, and with
authority to take all of the actions from time to time on behalf of the
Borrower, and in the name and stead of the Borrower, which Lender is authorized
to take under this Agreement and the Credit Documents or which Lender in its
good faith discretion deems necessary or advisable to cause Borrower to be in
compliance with any of the terms of this Agreement or any of the Credit
Documents or to carry out and enforce this Agreement and the Credit Documents.
The attorney or designee shall not be liable for any acts of commission or
omission nor for any error of judgment or mistake of fact or law which does not
arise from its gross negligence or willful misconduct. This power of attorney is
coupled with an interest and is irrevocable so long as any of the Obligations
remain unpaid or unperformed or there exists any commitment by the Lender which
could give rise to any Obligations.

             9.8    Unenforceability. If any term, provision or condition, or
any part thereof, of this Agreement or any of the other Credit Documents shall
for any reason be found or held invalid or unenforceable by any court or
Governmental Authority, such invalidity or unenforceability shall not affect the
remainder of such term, provision or condition, nor any other term, provision or
condition, and this Agreement and the other Credit Documents shall survive and
be construed as if such invalid or unenforceable term, provision or condition
had not been contained herein or therein; provided, however, that if any rate of
interest provided under this Agreement or any of the other Credit Documents does
or shall exceed the maximum interest rate permitted by law, then such rate of
interest shall immediately be deemed to be reduced to such maximum rate and all
previous payments of interest in excess of the maximum rate shall be deemed to
have been payments in reduction of principal and not of interest.

             9.9    Indemnification Concerning Fees. The Borrower agrees to
indemnify, protect and defend the Lender, and save the Lender harmless, from and
against any and all claims, demands, damages, losses, liabilities, obligations,
penalties, litigation, judgments, suits, actions, proceedings, costs and
expenses (including, without limitation, counsel fees and expenses) of any kind
or nature whatsoever which may at any time be imposed upon, paid or incurred by
or asserted or awarded against the Lender relating to, resulting from or arising
out of any broker's or finder's fee or commission which the Lender did not
directly contract to pay.

             9.10   Waiver of Trial by Jury. Each of the Borrower and the Lender
agrees that any action, suit or proceeding involving any claim, counterclaim or
cross-claim arising out of or in any way relating, directly or indirectly, to
this Agreement or any of the other Credit Documents, or any liabilities, rights
or interests of the Borrower, the Lender or any other Person arising out of or
in any way relating, directly or indirectly, to any of the foregoing, shall be
tried by a court and not by a jury. Each of the Borrower and the Lender hereby
waives any right to trial by jury in any such action, suit or proceeding, with
the understanding and agreement that this waiver constitutes a waiver of trial
by jury of all claims, counterclaims and cross-claims against all parties to
such actions, suits or proceedings, including claims, counterclaims and
cross-claims against parties who are not parties to this Agreement or the other
Credit Documents. This waiver is knowingly, willingly and voluntarily made by
each of the parties hereto, and each of the parties hereto acknowledges and
agrees that this waiver of trial by jury is a material aspect

                                       56
<PAGE>   62

of the agreements among them and that no representations of fact or opinion have
been made by any Person to induce this waiver of trial by jury or to modify,
limit or nullify its effect.

             9.11   Additional Waivers. The Borrower hereby waives, to the
extent the same may be waived under applicable law: (a) notice of acceptance of
this Agreement or any of the other Credit Documents by any other party hereto;
and (b) all claims and causes of action of the Borrower against the Lender for
punitive, exemplary, consequential, special or other indirect or
non-compensatory damages.

             9.12   Successors and Assigns; Transfers of Interests.

                    (a)    This Agreement shall be binding upon and inure to the
benefit of the Borrower, the Lender, all future holders of the Note and their
respective successors and assigns, except that the Borrower may not assign or
transfer any of its rights or obligations under this Agreement without the prior
written consent of the Lender.

                    (b)    The Lender may at any time, in its discretion,
assign, transfer or pledge to any Person, or grant to any Person a security
interest in, this Agreement, any of the other Credit Documents or any of its
rights hereunder or thereunder. In addition, the Lender may sell, in such
amounts, upon such terms and to such Persons as the Lender may determine,
participation in its interests under this Agreement or any of the other Credit
Documents. In the case of each such assignment, transfer, pledge, grant or sale
(i) the Lender may from time to time provide to the assignee, transferee,
pledgee, secured party or participant, any information and documents (or copies
thereof) relating to this Agreement and the other Credit Documents and related
transactions, and relating to the business, assets, operations, business
prospects or financial condition of the Borrower, Subsidiaries of the Borrower
and Other Obligors, and (ii) subject to Requirements of Law, the Lender agrees
to continue to administer this Agreement and the other Credit Documents subject
to compensation of the Lender by such assignees, transferees, pledgees, secured
parties or participants.

             9.13   Counterparts. This Agreement may be executed by one or more
of the parties to this Agreement on any number of separate counterparts and all
of said counterparts taken together shall be deemed to constitute one and the
same instrument.

             9.14   Governing Law. This Agreement, the Note and the other Credit
Documents, and the rights and obligations of the parties hereunder and
thereunder, shall be governed by and construed and interpreted in accordance
with the internal laws of the Commonwealth of Virginia, exclusive of principles
of conflicts of laws.

             9.15   Submission To Jurisdiction. The Borrower hereby irrevocably
and unconditionally:

                    (a)    submits for itself and its property in any legal
action or proceeding relating to this Agreement or any of the other Credit
Documents, or for recognition and enforcement of any judgment in respect
thereof, to the non-exclusive general jurisdiction of the

                                       57
<PAGE>   63

United States District Court for the Eastern District of Virginia or the
Circuit Court of Fairfax County, Virginia;

                    (b)    consents that any such action or proceeding may be
brought in such courts, and waives any objection that it may now or hereafter
have to the venue of any such action or proceeding in any such court or that
such action or proceeding was brought in an inconvenient court and agrees not to
plead or claim the same;

                    (c)    agrees that service of process in any such action or
proceeding may be effected by mailing a copy thereof by registered or certified
mail (or any substantially similar form of mail), postage prepaid, to the
Borrower at its address set forth in Subsection 9.3 or at such other address of
which the Lender shall have been notified pursuant thereto; and

                    (d)    agrees that nothing herein shall affect the right to
effect service of process in any other manner permitted by law or shall limit
the right to sue in any other jurisdiction.

             9.16   Release. The Borrower releases and forever waives and
relinquishes all claims, demands, obligations, liabilities and causes of action
of whatsoever kind or nature, whether known or unknown, which it has, may have,
or might have or assert now or in the future against the Lender and its
directors, officers, employees, attorneys, agents, successors, predecessors and
assigns and any Affiliates, Subsidiaries or related entities of the Lender and
their directors, officers, employees, attorneys, agents, successors,
predecessors and assigns, directly or indirectly, arising out of, based upon, or
in any manner connected with any transaction, event, circumstance, action,
failure to act, or occurrence of any sort or type, whether known or unknown,
which occurred, existed, was taken, permitted, or begun before the execution of
this Agreement.

             9.17   Consent to Relief from Stay. The Borrower acknowledges and
agrees that if the Collateral or any part thereof shall ever become the subject
of any bankruptcy or insolvency estate, then the Lender shall immediately become
entitled, among other relief to which the Lender may be entitled, to obtain upon
ex parte application therefor and without further notice of action of any kind,
(i) an order from the court prohibiting the use by the trustee in bankruptcy or
by the Borrower as debtor in possession of the Lender's "cash collateral" (as
such term is defined in Section 363 of the Bankruptcy Code) in connection with
the Loan, and (ii) an order from the Court granting immediate relief from the
automatic stay pursuant to Section 362 of the Bankruptcy Code so as to permit
the Lender to exercise all of its rights and remedies hereunder, under the other
Loan Documents and at law and in equity, and the Borrower further acknowledges
and agrees that the occurrence or existence of any Event of Default under this
Agreement shall, in and of itself, constitute "cause" for relief from the
automatic stay pursuant to the provisions of Section 362(d)(1) of the Bankruptcy
Code.

             9.18   Other Bankruptcy Relief. The Borrower acknowledges and
agrees that in the event of the filing of any voluntary or involuntary petition
in bankruptcy by or against the Borrower, the Borrower shall not assert or
request any other party to assert that the automatic

                                       58
<PAGE>   64

stay provided by Section 362 of the Bankruptcy Code shall operate or be
interpreted to stay, interdict, condition, reduce, or inhibit the ability of the
Lender to enforce any rights it has by virtue of this Agreement or the other
Loan Documents, or any other rights the Lender has, whether now or hereafter
acquired, against any person or entity which is not a debtor in such bankruptcy
proceedings or against any property owned by any such non-debtor; and further
that, in the event of the filing of any voluntary or involuntary petition in
bankruptcy by or against the Borrower, the Borrower shall not seek a
supplemental stay or any other relief, whether injunctive or otherwise, pursuant
to Section 105 of the Bankruptcy Code or any other provision of the Bankruptcy
Code, to stay, interdict, condition, reduce, or inhibit the ability of the
Lender to enforce any rights it has by virtue of this Agreement or the other
Loan Documents, or at law or in equity, or any other rights the Lender has,
whether now or hereafter acquired, against any person or entity which is not a
debtor in such bankruptcy proceedings, or against any property owned by any such
non-debtor.

             9.19   Forbearance by Lender. Subject to compliance with each and
every closing condition set forth in Section 5, the Lender agrees to forbear
from the exercise of its rights and remedies under the Credit Documents until

   On May 5, 1998, a class action lawsuit was filed against the Borrower in the
Superior Court of New Jersey in Bergen County, New Jersey. The complaint
alleges, among other things, that the Borrower, at its Learning Centers located
in the State of New Jersey, failed to provide certain educational services and
resources, misrepresented certain information respecting services, resources,
occupational opportunities and student outcomes and violated certain provisions
of the New Jersey Consumer Fraud Act. On November 19, 1999, the court certified
a class consisting of all persons who, during the six years immediately
preceding the commencement of this action, had enrolled in a course or courses
of study, education or training provided by the Borrower at its New Jersey
locations for which they incurred tuition expenses. On December 6, 1999, the
Borrower filed a motion with the Appellate Division of the Superior Court of New
Jersey to appeal the November 19, 1999 decision to certify a class. On January
19, 2000, that motion was denied. The Borrower is unable to estimate the outcome
of the matter or any potential liability.

   On July 9, 1999, a class action lawsuit was filed against the Borrower in the
Court of Common Pleas in Philadelphia County, Pennsylvania, on behalf of all
students who attended the Learning Center located on Market Street in
Philadelphia within four years of July 9, 1999, who have not obtained employment
in a computer-related job through the Borrower's placement services. The
complaint alleges, among other things, that this Learning Center failed to
provide certain educational services and resources, misrepresented certain
information respecting services, resources, occupational opportunities and
student outcomes, and violated certain provisions of the Pennsylvania Unfair
Trade Practices and Consumer Protection Law. The Borrower is unable to estimate
the outcome of the matter or any potential liability.

   Between June 1, 1998 and October 31, 1999, the Borrower was named as
defendant in four other lawsuits in Texas and New Jersey by individual students
or groups of students who formerly attended one of its Learning Centers. The
June 1, 1998 lawsuit has been settled. In two of the remaining lawsuits, various
present or former officers, directors and employees of the Borrower were also
named as defendants. In May of 2000, the officers and directors were dismissed
as defendants in these two lawsuits; however, those decisions have been
appealed. The complaints allege, among other things, that the Borrower, at the
affected Learning Centers, failed to provide plaintiffs with certain educational
services and resources and misrepresented certain information respecting
services, resources, and student outcomes and violated certain provisions of the
applicable state consumer laws. The Borrower is unable to estimate the outcome
of these matters or any potential liability.

   In December 1999, the Borrower received a subpoena from the Office of
Inspector General of the Department of Education for the production of various
documents and

                                       63
<PAGE>   69

materials related to the compensation of its admissions representatives and the
calculation of its student loan cohort default rates. The Office of Inspector
General also served subpoenas on the accounting firm that had audited the
Borrower's financial statements and the accounting firm that had performed the
Borrower's Title IV Program compliance audits, for copies of certain of their
audits, work papers and other materials prepared in the course of their work on
the Borrower's behalf. In discussion with the responsible attorney at the U.S.
Department of Justice in December 1999 regarding the December subpoena, the
Borrower's attorney determined that the subpoena was issued with respect to a
qui tam lawsuit filed against the Borrower in Federal District Court in Texas
alleging that the Borrower's compensation of certain employees was not in
compliance with provisions of Title IV of the Higher Education Act. In July
2000, the Borrower received a second subpoena from the Office of Inspector
General seeking certain additional information. The Borrower has responded to
both subpoenas. The Borrower's management believes that the compensation plans
are in compliance with the Higher Education Act.

   In addition to the lawsuits discussed above, the Borrower is a defendant in a
number of civil lawsuits involving current and former employees and other third
parties, which the Borrower considers incidental to its business and unlikely to
have a material effect on the Borrower's future operations. However, there can
be no assurance that these matters will not have a severe impact on the results
of operations of the Borrower in a future period, depending in part on the
results for such period.

   The Borrower intends to defend itself vigorously in the lawsuits referred to
above; however, there can be no assurance that the Borrower will be successful
in defending itself in any of these proceedings. Even if the Borrower prevails
on the merits in such litigation, the Borrower has incurred and expects to
continue to incur significant legal and other defense costs as a result of such
proceedings. These proceedings have involved and could continue to involve
substantial diversion of the time of some members of management. An adverse
determination in, or settlement of, such litigation could involve payment of
significant amounts, or could include terms in addition to such payments, or
could lead to other adverse consequences, including the suspension or
termination of the Borrower's licenses to operate within the respective state,
which would have a severe impact on the Borrower's business, financial condition
and results of operations.

trust, assignments, notices, consents and other documents as Secured Party may

interest in the Collateral and Secured Party's rights under this Agreement. In

as Secured Party may reasonably request, and to do such other things as Secured
Party may reasonably request, in order that all sums due and to become due to
Debtor under or in connection with such contract shall be duly assigned and paid
to Secured Party in accordance with the Federal Assignment of Claims Act and/or

interest in or lien upon any of the Collateral is or will be on file in any

modification or compromise of any kind with respect to any Receivable, other

well as other documents reasonably requested by Secured Party, previously or
hereafter coming into Debtor's possession or control and constituting,
evidencing, securing, guaranteeing or otherwise relating to, any of the
Collateral or proceeds of any of the Collateral;

                        (f)     no check, draft, money order or other item of
payment made or applied on account of any of the Obligations shall constitute a
final payment to Secured Party unless and until the item of payment shall be
honored and finally paid to Secured Party in immediately available funds;

Collateral Account or the Revolving Credit Cash Collateral Account until and
only to the extent that the balance in the L/C Cash Collateral Account exceeds
110% of the L/C Exposure, as defined in the Credit Agreement, and the balance in
the Revolving Credit Cash Collateral Account exceeds 110% of the Revolving
