              (e)    The words "hereof", "herein" and "hereunder" and words of

       SECTION 2. AMOUNT AND TERMS OF LOAN COMMITMENTS

       2.1    Revolving Credit Commitment. Subject to the terms and conditions
hereof, the Lender agrees to make revolving credit loans (individually, a
"Revolving Credit Loan" and, collectively, the "Revolving 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 use the

Revolving Credit Commitment by borrowing, paying the Revolving Credit Loans in
whole or in part, and reborrowing, all in accordance with and subject to the
terms and conditions of this Agreement, including Subsection 2.10.

       2.2    Revolving Credit Note. The Revolving Credit Loans made by the
Lender shall be evidenced by, and payable with interest in accordance with, the
Third Amended and Restated Revolving Credit Note dated May 15, 2000 (as amended,
modified, extended, renewed, supplemented or replaced from time to time, the
"Revolving Credit Note"), payable to the order of the Lender. The date and
amount of each Revolving Credit Loan made by the Lender, and the date and amount
of each payment or prepayment of principal thereof, as reflected on the Lender's
books and records with respect to the Revolving Credit Note, shall constitute
prima facie evidence, absent manifest error, of the accuracy of the information
so reflected. The Revolving Credit Note shall (a) be stated to mature on the
Revolving Credit Termination Date and (b) bear 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).

       2.3    Procedure for Revolving Credit Borrowing.

              (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 2.3(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)    Effective November 1, 2000, 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 on and
after November 1, 2000 if the Revolving Credit Loan would cause the total
principal amount of Revolving Credit Loans made and outstanding to exceed the
lesser of $2,500,000 or the then current Borrowing Base. Even if the total
principal amount of Revolving

Credit Loans outstanding shall at any time and for any reason exceed the lesser
of $2,500,000 or the then current Borrowing Base, 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 lesser
of $2,500,000 or the then current Borrowing Base, 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. The Borrower agrees to pay to the Lender a facility
fee from and including May 15, 2000 to the Revolving Credit Termination Date,
computed at the rate set forth below on the average daily amount of the
Revolving Credit Maximum Amount during the period for which payment is made,
payable monthly in arrears on the first day of each month, commencing on June 1,
2000, and on the Revolving Credit Termination Date or such earlier date as the
Revolving Credit Commitment shall terminate as provided herein.

              (a)    During monthly periods when the Revolving Credit Maximum
Amount exceeds or equals $3,000,000, the Facility Fee shall be 3% per annum.

              (b)    During monthly periods when the Revolving Credit Maximum
Amount is less than $3,000,000, the Facility Fee shall be 1% per annum.

       If the Borrower fully repays all debt under the Revolving Credit
Facility, terminates or cancels all Letters of Credit, and terminates all Credit
Facilities, by September 30, 2000, the Lender shall refund to the Borrower 75%
of all facility fees paid by the Borrower since June 1, 2000.

       If the Borrower fully repays all debt under the Revolving Credit
Facility, terminates or cancels all Letters of Credit, and terminates all Credit
Facilities, by December 15, 2000, the Lender shall refund to the Borrower 50% of
all facility fees paid by the Borrower since June 1, 2000.

       The Borrower will, effective with the payment due on June 1, 2000, no
longer have to pay an unused facility fee.

       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.

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.

              (c)    The Borrower shall pay to the Lender all Prepayment
Sources, to the extent required under this Agreement, and which are
characterized as Standard Prepayments, and which shall permanently reduce the
amount of Revolving Credit Loans available to the Borrower. The Borrower's
failure to receive any Prepayment Source by the date necessary to reduce the
Revolving Credit Maximum Amount as required by this Agreement shall not relieve
the Borrower of its obligation to permanently reduce the amount outstanding
under the Revolving Credit Facility by the dates and in the amounts as required
in this Agreement.

              (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 deleted).

       2.16   Payments. All payments (including prepayments) to be made by the
Borrower under this Agreement, the Note or any other Credit Document, whether on
account of principal, interest, fees, expenses or other amounts, shall be made
without deduction, setoff or 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.

       2.18   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 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.

       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
$3,300,000 through and including July 31, 2000, and $2,575,000 thereafter. 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, from and after September 30, 2000, no Letter
of Credit (including any renewal or extension thereof, whether or not automatic)
shall have an expiry date which is later than six months following the Revolving
Credit Termination Date; 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.

              (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 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.

              (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

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.

       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

                     (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 in respect of
obligations of the Borrower.

       3.9    Inconsistency in Documents. In the event of any conflict or
inconsistency between any provision of any L/C Agreement, or the interpretation
or construction thereof, and any provision of this Agreement, or the
interpretation or construction thereof, then the provision of this Agreement, or
the interpretation or construction thereof, shall control.

       3.10   Cash Collateral for Letters of Credit.

              (a)    Beginning on August 1, 2000, and each month thereafter
until the amount on deposit in the Cash Collateral Account equals 110% of the
face amount of all Letters of Credit, the Borrower shall deposit $250,000 into
an interest-bearing account maintained at the Lender (the "Cash Collateral
Account"). The sums on deposit in the Cash Collateral Account shall secure
payment of all Letters of Credit.

              (b)    In addition to and not in substitution of the Borrower's
payment obligations set forth in Subsection 3.10(a) above, the Borrower shall
pay to the Lender, for deposit into the Cash Collateral Account, all Excess

              (b)    the statement of income and retained earnings of the
Borrower for the quarterly accounting period of the Borrower ended January 31,

such quarterly accounting period and for the current fiscal year of the Borrower

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

other condition of the Borrower from the date of the most recent financial

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

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

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

Documents or any of the transactions contemplated hereby or thereby, or (b)

expected to have a Material Adverse Effect.

Borrower.

       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 fair
valuation, of the Borrower will, as of such date, 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.

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.

              (c)    With respect to each employee welfare benefit plan, as
defined in Section 3(1) of ERISA (a "Welfare Plan"), established or maintained

Borrower nor, to the actual knowledge of any director or officer of the Borrower
or any Subsidiary of the Borrower, any other Person who or which is a party in
interest as defined in Section 3(14) of ERISA, has acted or failed to act with
respect to the Welfare Plan in any manner which constitutes a breach of
fiduciary responsibility within the meaning of Title I, Subtitle B, Part 4 of

of ERISA, or any other violation of ERISA;

and other requirements of the Code and ERISA.

              (e)    There are no actions, suits or claims pending or, to the
best knowledge of the Borrower or any Subsidiary of the Borrower, threatened

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

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 all
Revolving Credit Loans for working capital and to fund a limited amount of
Capital Expenditures.

       4.19   CLCQ and Delta College.

              (a)    Each of CLCQ and Delta College (i) is a Quebec corporation
duly organized, validly existing and in good standing, (ii) 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, (iii) is duly
qualified to conduct business and is in good standing in each jurisdiction in
which such qualification is required by applicable Requirement of Law, and (iv)
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.

              (b)    The authorized capital stock of CLCQ consists of two (2)
classes, namely Common Shares, having voting rights, and Dividend Access Shares,
having no voting rights except as provided in Sections 10.1, 11.1 and 12.2 of
the Articles of Incorporation of CLCQ. All of the issued and outstanding capital
stock of each class of CLCQ stock is legally and beneficially owned by the
persons and in the amounts set forth in Exhibit F attached hereto. All of the
issued and outstanding capital stock of each class of Delta College is legally
and beneficially owned by CLCQ, with the discretionary power and right to
exercise all rights and privileges, including voting rights, with respect
thereto.

              (c)    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 CLCQ
or Delta College or against any of their properties or revenues which, if
determined adversely to CLCQ or Delta College, as the case may be, 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 CLCQ or
Delta College and any employees of CLCQ or Delta College, respectively, or
between CLCQ or Delta College and any union or other collective bargaining unit
representing employees of CLCQ or Delta College, respectively, which could
reasonably be expected to have a Material Adverse Effect.

              (d)    Neither CLCQ nor Delta College is in default under or with
respect to any Contractual Obligation in any respect which could reasonably be
expected to have a Material Adverse Effect. The sum of the assets of each of
Delta College and CLCQ, at a fair valuation, exceeds the debts of CLCQ and Delta
College, respectively, exclusive, in the case of Delta College, of debts of
Delta College to the Borrower or CLCQ. The present fair salable value of the
assets of each of CLCQ and Delta College is greater than the amount required to
pay the liability on the debts of CLCQ and Delta College, respectively, as such
debts become absolute and matured, exclusive, in the case of Delta College, of
debts of Delta College to the Borrower or CLCQ. Each of CLCQ and Delta College
has 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.

              (e)    Each of CLCQ and Delta College has good title to all of its
property, and none of such property is subject to any Lien, except as permitted
by Subsection 7.3.

              (f)    To the Borrower's knowledge: (i) no Hazardous Substance has
been released, discharged, spilled, emitted or disposed of on any Obligor Use
Property by CLCQ or Delta College or under any circumstances as a result of
which CLCQ or Delta College would be liable or financially responsible for
damages or the cost of remediation or clean-up; (ii) there is no existing
Hazardous Substance Contamination of any Obligor Use Property which was caused
by CLCQ or Delta College or under circumstances as a result of which CLCQ or
Delta College would be liable or financially responsible for damages or the cost
of remediation or clean-up; (iii) all operations now or previously conducted on
Obligor Use Property by CLCQ or Delta College comply with all Environmental
Laws; (iv) no underground storage tanks have been installed on any Obligor Use
Property by CLCQ or Delta College or under circumstances as a result of which
CLCQ or Delta College would be liable or financially responsible for damages or
the cost of removal, remediation or clean-up; and (v) neither CLCQ nor Delta
College has received, and neither CLCQ nor Delta College is aware of, any
Environmental Claim against, relating to or affecting in any way CLCQ or Delta
College or the use of any Obligor use Property by CLCQ or Delta College or any
operations conducted on any Obligor Use Property by CLCQ or Delta College.

              (g)    Each of CLCQ and Delta College has filed or caused to be
filed all tax returns which are required to be filed by it, and each of CLCQ and
Delta College has paid all taxes shown to be due and payable on said returns 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 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 CLCQ or
Delta College, as applicable), and, to the knowledge of the Borrower, no claim
is being asserted with respect to any such tax, fee or other charge. No tax lien
has been filed against CLCQ or Delta College or any of their assets.

       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 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

amended to include such Additional/More Restrictive Provisions. If such credit

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

       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 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 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.

              (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.

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

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 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

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 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

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   Waiver by Lender. Subject to compliance with each and every
closing condition set forth in Section 5, the Lender waives (as to (a), (b) and
(c), such waiver shall be a point-in-time waiver) the Borrower's failure to

ITEM 3.  LEGAL PROCEEDINGS

     Active Litigation

     On May 5, 1998, a class action lawsuit was filed against CLC in the
Superior Court of New Jersey in Bergen County, New Jersey. The complaint
alleges, among other things, that CLC Learning Centers in 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 CLC at CLC's New Jersey locations for which they incurred tuition
expenses. On December 6, 1999, CLC 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. CLC is unable to
estimate the outcome of the matter or any potential liability.

     On July 9, 1999, a class action lawsuit was filed against CLC 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
six years of July 9, 1999, who have not obtained employment in a
computer-related job through our placement services. On August 2, 1999, the case
was removed to the United States District Court for the Eastern District of
Pennsylvania. On October 12, 1999, the United States District Court for the
Eastern District of Pennsylvania remanded the case to the Court of Common Pleas
in Philadelphia County, Pennsylvania. 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. CLC is
unable to estimate the outcome of the matter or any potential liability.

     Between June 1, 1998 and October 31, 1999, CLC was named as defendant in
three other lawsuits in Texas and New Jersey by individual students or groups of
students who formerly attended one of CLC's Learning Centers. In two of these
lawsuits, various present and former officers, directors and employees of CLC
have also been named as defendants. The complaints allege, among other things,
that CLC's 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. CLC is unable to estimate the
outcome of these matters or any potential liability.

     In addition to the lawsuits discussed above, CLC is a defendant in a number
of civil lawsuits involving current and former employees, which we consider
incidental to our business and unlikely to have a material effect on our future
operations. However, there can be no assurance that these matters will not have
a material adverse effect on CLC's results of operations in a future period,
depending in part on the results for such period.

     CLC intends to defend itself vigorously in the lawsuits referred to above;
however, there can be no assurance that CLC will be successful in defending
itself in any of these proceedings. Even if CLC prevails on the merits in such
litigation, CLC expects to incur significant legal and other defense costs as a
result of such proceedings. These proceedings could involve substantial
diversion of the time of some members of management, and an adverse
determination in, or settlement of, such litigation could involve the payment of
significant amounts, or could include terms in addition to such payments, which
could have a severe impact on CLC's business, financial condition and results of
operations.

     There can be no assurance that additional legal proceedings will not be
filed or that adverse action will not be initiated against CLC, either by
federal or state regulators, or other parties. Any such legal proceedings or
adverse action could have a severe impact on our business, financial condition
and results of operations.

     Settled Litigation

     During fiscal year 1999 and 2000, CLC was named as defendant in five other
lawsuits in California, Michigan, Texas and Virginia by individual students or
groups of students who formerly attended one of its Learning Centers. The
complaints allege, among other things, that CLC's 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.
During the course of fiscal 2000, these cases were settled resulting in payments
to the former students of immaterial amounts. Settlement expenses are combined
with legal fees and included within general and administrative expenses in the
consolidated financial statements.

     In addition to the student lawsuits, the Attorney General of Illinois filed
a complaint against CLC in Circuit Court in Cook County, Illinois, on March 10,
1998, asserting that CLC had violated the Illinois Private Business and
Vocational Schools Act and the Illinois Consumer Fraud and Deceptive Business
Practices Act (the "Acts") at its Schaumburg, Illinois Learning Center. The
complaint alleged that at the Schaumburg Learning Center, CLC failed to provide
certain educational services and resources and misrepresented certain
information respecting services, resources, occupational opportunities and
student outcomes. On June 8, 1998, CLC reached an agreement with the Attorney
General settling the litigation in the form of a final judgment and Consent
Decree approved by the court ("Consent Decree"). The settlement includes payment
of a voluntary contribution of $90,000 to the Attorney General's consumer
education fund, a provision annually for a four year period of $95,000 worth of
computer hardware and software to schools, programs, community sites and other
non-profit and public institutions in the Chicago area designated by the
Attorney General, and $10,000 worth of training in computer skills annually at
CLC's Schaumburg or Chicago Learning Centers for teachers and other community
based personnel to enable them to make effective use of the computer equipment.
CLC also agreed to take certain measures to assure compliance with state
regulatory requirements, and to establish an ombudsman program and binding
arbitration for the resolution of certain student complaints. CLC has
implemented the measures called for under the first and second years of the
Consent Decree. Failure by CLC to continue to comply with the terms of the
Consent Decree could result in adverse action against the Learning Centers
located in Illinois, including suspension or termination of our licenses to
operate within Illinois and other sanctions. The loss of operating authority in
Illinois could have a material adverse effect on CLC.

time amended, the "Assignment") pursuant to which the Borrower has assigned and
granted to the Lender a security interest in all deposit accounts now or

________________ , _____________ , and ______________ (collectively, the
"Deposit Accounts"). Copies of the Assignment and the Security Agreement are
enclosed herewith.
