2.  The Loans.

    2.1   The $15,000,000.00 Revolving Loan.

Promissory Note (the "$15,000,000.00 Note") in the stated principal amount of
$15,000,000.00 dated of even date herewith and made payable to the order of
Lender.  Lender shall, subject to the terms and conditions of this Agreement,
make a Revolving Loan to Borrower that will create indebtedness evidenced by
the $15,000,000.00 Note.  That Revolving Loan will be made by the making of one
or more Advances.  Lender's agreement to make such Revolving Loan establishes a
$15,000,000.00 line of credit (the "$15,000,000.00 Line of Credit"); and each
Advance made under the $15,000,000.00 Line of Credit shall, at the time such
Advance is made, create principal indebtedness evidenced by the $15,000,000.00
Note, in the amount of that Advance.

          2.1.2  Lender shall have no obligation to make any Advance under the
$15,000,000.00 Line of Credit on or after June 10, 1998.  In addition, Lender
shall have no obligation to make an Advance under the $15,000,000.00 Line of
Credit if making that Advance would cause the unpaid principal balance of the
$15,000,000.00 Note to exceed the Current Credit Limit.  As of any particular
date, and until June 10, 1997, the Current Credit Limit





                                       9
   10
shall equal the lesser of (i) $15,000,000.00, or (ii) the Borrowing Base.  As
of any particular date beginning on June 10, 1997, and continuing until June
10, 1998, the Current Credit Limit shall equal the lesser of (i) the amount by
which $15,000,000.00 exceeds the unpaid principal balance of the First Term
Note, or (ii) the Borrowing Base.  Borrower shall not, at any time, allow the
unpaid principal balance of the $15,000,000.00 Note to exceed the Current
Credit Limit.  Borrower shall not at any time allow the sum of the unpaid
principal balances of the First Term Note and the Second Term Note to exceed an
amount equal to the Borrowing Base.

          2.1.3  Within sixty (60) days after Lender receives Borrower's Annual
Audited Financial Statements for Borrower's 1995 fiscal year, Lender will give
Borrower notice of Lender's intentions regarding renewal and extension of the
$15,000,000.00 Line of Credit.  However, Lender shall not be obligated to renew
or extend the $15,000,000.00 Line of Credit on the same terms or on any other
terms.  If Lender fails to give such notice, Borrower's sole remedy shall be to
receive such a notice promptly after Borrower's request therefor.

          2.1.4  Beginning on the date of this Agreement and continuing until
June 10, 1998, a commitment fee shall accrue daily with respect to the unused
portion of the $15,000,000.00 Line of Credit.  The amount of that fee that
shall accrue each day shall equal the product of (i) 1/360 times (ii) .0025
times (iii) the amount by which a certain difference exceeds the outstanding,
unpaid principal balance of the $15,000,000.00 Note, on such day; such certain
difference being the difference produced by subtracting the unpaid, principal
balance of the First Term Note from $15,000,000.00.  On each date when a
payment is due under the $15,000,000.00 Note (or would be due if any accrued
interest were owing thereunder), Borrower shall pay to Lender the accrued,
unpaid portion of such commitment fee.

          2.1.5  If Borrower has not previously paid an initial commitment fee
of $18,750.00 to Lender, in consideration of Lender's agreement to make the
Loans, then Borrower shall promptly pay such initial commitment fee, in cash,
to Lender.

    2.2   The Term Loans.

          2.2.1  Subject to the terms and conditions hereof, Lender shall make,
and Borrower shall accept, the First Term Loan on June 10, 1997.  The First
Term Loan shall be in an amount equal to the lesser of (i) the unpaid,
principal balance of the $15,000,000.00 Note on June 10, 1997, or (ii) the
Borrowing Base on June 10, 1997.  The First Term Loan shall be made by
Borrower's execution and delivery to Lender, and Lender's acceptance of, a
Promissory Note

delivery and acceptance of the First Term Note shall be in renewal and

and Borrower shall accept, the Second Term Loan on June 10, 1998.  The Second

amount by which the Borrowing Base exceeds the unpaid balance of the First Term
Note on June 10, 1998.  The Second Term Loan shall be made by Borrower's
execution and delivery to Lender, and Lender's acceptance of, a Promissory Note
(the "Second Term Note") in the form attached hereto as EXHIBIT "C"; and, the
delivery and acceptance of the Second Term Note shall be in renewal and
extension of unpaid principal indebtedness evidenced by the $15,000,000.00 Note
immediately before the execution and delivery of the Second Term Note.  The
stated principal amount of the Second Term Note shall be the amount of the
Second Term Loan.

    2.3   Prepayments.  Borrower may prepay any and all of the indebtedness
evidenced by one or more of the Notes, in whole or in part, if:  (i) Borrower
simultaneously pays all interest that has accrued on any principal indebtedness

option (the "Rate Option") to designate a LIBO Rate for that Interest Period.
Borrower may exercise the Rate Option by either (i) giving written notice of

                                       11
   12
Option is so exercised, then a LIBO Interest Period of the length specified in
that notice shall begin on the date specified in that notice.  For each LIBO
Interest Period (i.e., an Interest Period with respect to which a Rate Option
has been exercised), the LIBO Rate shall be:

          (i)    Lender's 30-Day LIBO Rate plus the Additional Percentage,

    "90-Day LIBO Rate," and "180-Day LIBO Rate" means the rate so designated by
    Lender and established by Lender from time to time with reference to the
    rate(s) at which deposits in U.S. Dollars are offered to Lender in the
    interbank





                                       12
   13
    eurodollar market, for periods of 30 days, 60 days, 90 days and 180 days,
    respectively; and those rates may not be the lowest rates charged by
    Lender.

          (e)    The Additional Percentage shall be 1.50% unless adjusted in
    accordance with this Paragraph (e).  If, before Borrower's Annual Audited
    Financial Statements for 1996 are available, Borrower advises Lender that,
    in Borrower's opinion, Borrower's operating income (determined in
    accordance with Generally Accepted Accounting Principles) for 1996 will be
    at least $14,000,000.00, then the Additional Percentage shall be adjusted
    to 1.30% effective as of the first day of Borrower's 1997 fiscal year;
    provided, however, that if Borrower's Annual Audited Financial Statements
    for 1996 show that such operating income was not at least $14,000,000.00,
    then such adjustment in the Additional Percentage shall be of no effect, so
    that the Additional Percentage for 1997 shall be 1.50%.  If, before
    Borrower's Annual Audited Financial Statements for 1997 are available,
    Borrower advises Lender that, in Borrower's opinion, Borrower's operating
    income for 1997 will be at least $17,000,000.00, then the Additional
    Percentage shall be adjusted to 1.25% effective as of the first day of
    Borrower's 1998 fiscal year; provided, however, that if Borrower's Annual
    Audited Financial Statements for 1997 show that such operating income was
    not at least $17,000,000.00, then such adjustment in the Additional
    Percentage shall be of no effect, so that the Additional Percentage for
    1998 and each year thereafter shall be 1.50%.  If Borrower's operating
    income for 1997 is at least $17,000,000.00, then the Additional Percentage
    shall be 1.25% thereafter until the date immediately following Borrower's
    first fiscal year, if any, in which its operating income is less than
    $17,000,000.00; and, on such date, the Additional Percentage shall return
    to 1.50% and remain at 1.50% at all times thereafter.  Any calculation of
    accrued interest based on an Additional Percentage that is less than 1.50%
    shall be provisional unless and until a determination is made from
    Borrower's Annual Audited Financial Statements that the Additional
    Percentage was appropriately adjusted.

          (f)    The "Prime-Based Rate" shall be the Prime Rate, except that at
    any time when the Additional Percentage is less than 1.50%, the Prime-Based
    Rate shall be the difference produced by subtracting 0.25% from the Prime
    Rate.

    3.3   Special Provisions Regarding the Contract Rate.  If Lender determines
(which determination shall be presumed correct absent evidence of error):





                                       13
   14
    (i)   Unavailability.  At the beginning of any LIBO Interest Period, that 
          by reason of any one (1) or more circumstances arising on or after the
          date of this Agreement, dollar deposits in an amount substantially
          equal to the unpaid balance of the Loans (and for a period
          substantially equal to the LIBO Interest Period) are not generally
          available in the interbank eurodollar market, or adequate and fair
          means do not exist for ascertaining the LIBO-Based Rate, then the
          Contract Rate during that Interest Period shall equal the Prime- Based
          Rate until Lender notifies Borrower that such circumstances no longer 
          exist.
        
    (ii)  Illegality.  At any time, that the initiation, or continued use, of
          the LIBO-Based Rate as a basis for determining the Contract Rate has
          become unlawful under Lender's good faith interpretation of any law,
          governmental rule, regulation, guideline or order (or would conflict
          with any such rule, regulation, guideline or order not having the
          force of law), or has become impractical as a result of a contingency
          occurring on or after the date of this Agreement which materially and
          adversely affects the interbank eurodollar market, then the Contract
          Rate shall thereafter equal the Prime-Based Rate.

    execution shall not be effectively stayed; or

          (f)    Borrower or Guarantor claims that at any time after the
    Security Effective Date Lender does not, or will not, have a valid,
    first-priority Lien as provided in the Loan Documents, on any Collateral
    purportedly provided by Borrower, or that either this Agreement or any one

                                       25
   26
(1) declare all, or any part, of all Indebtedness evidenced by any of the Notes
to be, and thereupon all the same shall forthwith become, immediately due and
payable; (2) terminate all Commitments; and (3) exercise any and all other
rights pursuant to the Loan Documents.

    8.2   Other Remedies.  In addition to and cumulative of any rights or
remedies provided in Section 8.1 hereof, if any one or more Events of Default
shall have occurred, Lender may proceed to protect and enforce its rights
hereunder by any appropriate proceedings, and the Liens evidenced by the
Security Documents shall be subject to foreclosure in any commercially
reasonable manner.  Lender may also proceed to enforce the specific performance
of any covenant contained in any of the Loan Documents, to enforce the payment
of the Notes, and to enforce any other legal or equitable right provided under
any of the Loan Documents or otherwise existing under any law.

    8.3   Remedies Cumulative.  No remedy, right or power conferred upon Lender
is intended to be exclusive of any other remedy, right or power given hereunder
or now or hereafter existing at law, in equity, or otherwise, and all such
remedies, rights and powers shall be cumulative.

    8.4   Notice and Right to Cure.  Any provisions (other than the last
sentence of this Section 8.4) herein to the contrary notwithstanding, Lender
shall not, as the result of any Curable Event of Default, exercise any remedy
provided in any of the Loan Documents unless Lender has previously given
written notice of that Curable Event of Default to Borrower and that Curable
Event of Default has continued for a certain period (the "Cure Period") after
such written notice was so given.  With respect to each Curable Event of
Default that is a failure to pay, or a default in paying, any amount of money,
the Cure Period shall be ten (10) days; and with respect to all other Curable
Events of Default, the Cure Period shall be thirty (30) days.  As used herein,
"Curable Event of Default" means any Event of Default except any event
described in Subsections (d), (e), (f), (i), (j), (k), (l), or (m) of Section
8.1.  In no event shall Lender have any obligation to advance any funds to
Borrower, at a time when an Event of Default or a Default exists.

9.  Miscellaneous.

    9.1   No Waiver.  Neither Lender's failure to exercise, nor its delay in
exercising, any power or right under the other Loan Documents shall operate as
a waiver thereof.  Neither any single or partial exercise of any such right or
power, nor any abandonment or discontinuance of steps to enforce such a right
or power, shall





                                       26
   27
preclude any other exercise thereof or of any other right or power.  No course
of dealing between Borrower and Lender shall operate as a waiver of any right
of Lender.  No modification or waiver of any provision of any Loan Document,
nor any consent to any departure therefrom, shall be effective unless the same
shall be in writing and signed by the person against whom enforcement thereof
is sought, and then such waiver or consent shall be effective only in the
specific instance for which given.

    9.2   Notices.  All notices under the Loan Documents shall be in writing
and either (i) personally delivered against receipt therefor, (ii) sent by
overnight courier against receipt therefor, or (iii) mailed by registered or
certified United States mail, return receipt requested, addressed as follows:

          (a)    If to Borrower:

                 Steck-Vaughn Company
                 8701 North MoPac, Suite 200
                 Austin, Texas  78759
                 Attention:  Vice President, Finance; with a copy to:

                 National Education Corporation
                 2601 Main Street
                 Irvine, California  92714
                 Attention:  General Counsel

          (b)    If to Lender:

                 NationsBank of Texas, N.A.
                 P.O. Box 908
                 Austin, Texas 78781-0908
                 (Attention:  Ms. Sylvia H. Maggio);

or to such other address of a party hereto as that party may designate by
notice hereunder.  Notices shall be deemed to have been given when personally
delivered or, if mailed, on the next Business Day after mailing.

    9.3   Governing Law.  Each Loan Document shall be governed by and construed
in accordance with the laws of the State of Texas and the United States of
America.  Any legal proceeding against Lender arising out of, or in connection
with, any of the Loan Documents shall be brought in the District Courts of
Travis County, Texas, or in the United States District Court for the Western
District of Texas, Austin Division.

    9.4   Survival; Parties Bound.  All representations, warranties, covenants
and agreements made by or on behalf of





                                       27
   28
Borrower in connection herewith shall survive the execution and delivery of the
Loan Documents, shall not be affected by any investigation made by any Person,
shall bind Borrower and its successors and assigns, and shall inure to the
benefit of Lender and its successors and assigns.  Lender's agreement to make
Loans to Borrower shall not inure to the benefit of any successor or assign of
Borrower.  The term of this Agreement shall be until the final maturity of all
the Notes and the payment of all amounts due under the Loan Documents,
whereupon it shall terminate; provided, however, that if Borrower pays all
amounts owing under the Loan Documents and agrees in writing that Lender has no
further obligations under the Loan Documents, then this Agreement shall
terminate.

    9.5   Counterparts.  This Agreement may be executed in several identical
counterparts, and by the parties hereto on separate counterparts; and each
counterpart, when so executed and delivered, shall constitute an original
instrument.  All such separate counterparts shall constitute but one and the
same instrument.

    9.6   Usury Not Intended; Refund of Any Excess Payments.  It is the intent
of the parties in the execution and performance of this Agreement to contract
in strict compliance with the usury laws of the State of Texas and the United
States of America from time to time in effect.  In furtherance thereof, Lender
and Borrower stipulate and agree that none of the terms and provisions
contained in the Loan Documents shall ever be construed to create a contract to
pay for the use, forbearance or detention of money, interest at a rate in
excess of the Highest Lawful Rate, and that for purposes hereof "interest"
shall include the aggregate of all charges which constitute interest under such
laws and are contracted for, reserved, taken, charged or received under the
Loan Documents. In determining whether or not the interest paid or payable,
under any specific contingency, exceeds the Highest Lawful Rate, Borrower and
Lender shall, to the maximum extent permitted under applicable law, (a) treat
all Loans as but a single extension of credit (and Borrower and Lender agree
that such is the case and that provision herein for multiple Loans and Notes is
for convenience only), (b) characterize any nonprincipal payment as an expense,
fee or premium rather than as interest, (c) exclude voluntary prepayments and
the effects thereof, and (d) "spread" the total amount of interest throughout
the entire contemplated term of the Loans.  The provisions of this paragraph
shall control over all other provisions of the Loan Documents which may be in
apparent conflict herewith.

    9.7   Captions.  The headings and captions appearing in the Loan Documents
have been included solely for convenience and shall not be considered in
construing the Loan Documents.





                                       28
   29
    9.8   Expenses.  Any provision to the contrary notwithstanding, and whether
or not the transactions contemplated by this Agreement shall be consummated,
Borrower shall pay on demand all out-of-pocket expenses (including, without
limitation, the fees and expenses of counsel for Lender) in connection with the
negotiation, preparation, execution, filing, recording, refiling, re-recording,
modification, supplementing and waiver of the Loan Documents and the making,
servicing and collection of the Loans.  Borrower's obligations under this and
the following section shall survive the termination of this Agreement and the
payment of the Notes.

    9.9   Indemnification.  Borrower shall indemnify, defend and hold Lender
harmless from and against any and all loss, liability, obligation, damage,
penalty, judgment, claim, deficiency and expense (including interest,
penalties, attorneys' fees and amounts paid in settlement) to which Lender may
become subject arising out of or based upon the Loan Documents or any Loan,
except for Lender's failure to perform its obligations under the Loan Documents
or any Legal Requirements.

    9.10  Entire Agreement.  The Loan Documents embody the entire agreement
between Borrower and Lender and supersede all prior proposals, agreements and
understandings relating to the subject matter hereof.  Each of Lender and
Borrower certifies that it is relying on no representation, warranty, covenant
or agreement except for those set forth in the Loan Documents.

    9.11  Severability.  If any provision of any Loan Documents shall be
invalid, illegal or unenforceable in any respect under any applicable law, the
validity, legality and enforceability of the remaining provisions shall not be
affected or impaired thereby.

    9.12  Sale or Assignment.  Lender reserves the right, in its sole
discretion, without notice to Borrower, to sell participations in all or any
part of any Loan as long as Lender remains the "lead bank."

    9.13  Loan Agreement Controls.  If there are any conflicts or
inconsistencies among this Agreement and any of the other Loan Documents, this
Agreement shall prevail and control.

    9.14  Commitment.  Lender has no commitment to lend sums to Borrower other
than as specifically set forth herein.

    9.15  Arbitration.

          (a)  Basic Requirements.  Any controversy or claim between or among
    any of the Parties and Lender, including, but not limited to, any claim
    arising out of or relating to this





                                       29
   30
    Agreement or any related agreements or instruments and any claim based on
    or arising from any alleged tort, shall be determined by binding
    arbitration in accordance with the Federal Arbitration Act (or if not
    applicable, the applicable state law), the Rules of Practice and Procedure
    for the Arbitration of Commercial Disputes of Judicial Arbitration and
    Mediation Services, Inc. (J.A.M.S.) and the "Special Rules" set forth
    below.  In the event of any inconsistency, the Special Rules shall control.
    Judgment upon any arbitration award may be entered in any court having
    jurisdiction.  Any one or more of the Parties, and/or Lender, may bring an
    action, including a summary or expedited proceeding, to compel arbitration
    of any controversy or claim to which this Agreement applies, in any court
    having jurisdiction over such action.

          (b)  Special Rules.  The arbitration shall be (i) conducted in the
    city of Borrower's domicile at the time of this Agreement's execution, and
    (ii) administered by J.A.M.S., who will appoint an arbitrator.  If J.A.M.S.
    is unable or legally precluded from administering the arbitration, then the
    American Arbitration Association will serve.  All arbitration hearings will
    be commenced within ninety (90) days of the demand for arbitration; and,
    the arbitrator shall, only upon a showing of cause, be permitted to extend
    the commencement of such hearing for no more than an additional sixty (60)
    days.

          (c)  Reservation of Rights.  Nothing in this Agreement shall be
    deemed to (i) limit the applicability of any otherwise applicable statutes
    of limitation or any waivers contained in this Agreement; or (ii) be a
    waiver by Lender of the protection afforded to it by 12 U.S.C Section 91 or
    any substantially equivalent state law; or (iii) limit the right of Lender
    (a) to exercise self help remedies as permitted by the Texas Uniform
    Commercial Code - Secured Transactions, or (b) to foreclosure of any lien
    or security interest against the Collateral, or (c) to obtain from a court
    provisional or ancillary remedies such as (but not limited to) injunctive
    relief, writ of possession, or the appointment of a receiver.  Lender may
    exercise such self help rights, cause a foreclosure of any such lien or
    security interest, or obtain any such provisional or ancillary remedies
    before, during, or after the pendency of any arbitration proceeding brought
    pursuant to this Agreement.  Neither Lender's exercise of self help
    remedies, nor Lender's institution or maintenance of an action for
    foreclosure or any such provisional or ancillary remedies, shall constitute
    a waiver of the right of any of the Parties, or Lender, to compel
    arbitration of the merits of the





                                       30
   31
    controversy or claim occasioning resort to such exercise, institution or
    maintenance.

    9.16  Waiver of Offset Rights.  Lender shall have no right to offset any of
Borrower's funds or moneys on deposit with Lender against any of Borrower's
liabilities or obligations under the Loan Documents; provided, however that
this Section 9.16 shall not impair or diminish any security interest granted by
Borrower or Lender's rights to enforce any such security interest.

    THIS WRITTEN AGREEMENT REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES
AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES.
