corporation ("NEC") (the "Merger") (24,516,622 shares based on the number of
shares of Sylvan Common Stock outstanding on March 17, 1997) (the "Share
Issuance"), pursuant to the Agreement and Plan of Reorganization dated as of
March 12, 1997 (the "Merger Agreement") by and between Sylvan and NEC; (ii)
amend Sylvan's Charter to reduce the term served by directors of Sylvan from
three years to one year and to eliminate separate classes of Sylvan directors
(the "Directors Amendment"); (iii) amend Sylvan's Charter to increase the number
of authorized shares of Sylvan Common Stock from 40,000,000 shares to 90,000,000
shares (the "Common Shares Amendment"); (iv) amend Sylvan's Charter to increase
from 250,000 shares to 400,000 shares the number of shares of Preferred Stock of
Sylvan, $.01 par value per share, which are designated as Junior Participating
Preferred Stock (the "Preferred Shares Amendment" and, together with the
Directors Amendment and the Common Shares Amendment, the "Charter Amendments");
(v) amend Sylvan's Amended and Restated 1993 Stock Option Plan (the "1993 Plan")
to provide for an increase of 2,575,000 shares in the total number of shares of
Sylvan Common Stock currently authorized for issuance under the 1993 Plan (which
would increase the total number of shares authorized for issuance pursuant to
the 1993 Plan from 2,625,000 to 5,200,000) (the "1993 Plan Amendment"); (vi)
amend Sylvan's 1996 Senior Management Stock Option Plan (the "Management Plan")
to provide for an increase of 1,000,000 shares in the total number of shares of
Sylvan Common Stock currently authorized for issuance under the Management Plan
(which would increase the total number of shares authorized for issuance
pursuant to the Management Plan from 2,250,000 to 3,250,000) (the "Management
Plan Amendment" and, together with the 1993 Plan Amendment, the "Plan
Amendments"); (vii) elect to the Sylvan Board of Directors, effective upon the
consummation of the Merger, each of Sam Yau, Richard C. Blum, David C. Jones,
and Michael R. Klein (each of whom is currently an NEC director), and R.
Christopher Hoehn-Saric, Douglas L. Becker, R. William Pollock, Nancy A. Cole,
Donald V. Berlanti and J. Phillip Samper (collectively, the "Merger Nominees"),
to serve until the next Annual Meeting of Sylvan stockholders and until their
successors are elected and qualify; (viii) elect to the Sylvan Board of
Directors, in the event the Merger is terminated, or the Merger Nominees are not
elected, each of R. Christopher Hoehn-Saric, Douglas L. Becker, J. Phillip
Samper, Donald V. Berlanti, Nancy A. Cole, James H. McGuire and R. William
Pollock (the "Contingent Nominees" and, together with the Merger Nominees, the
"Sylvan Board Nominees"), to serve until the next Annual Meeting of Sylvan
stockholders and until their successors are elected and qualify; (ix) ratify and
confirm the selection of Ernst & Young LLP as Sylvan's independent auditors for
the year ending December 31, 1997 (the "Auditor Confirmation"); and (x) transact
such other matters as may properly come before the Sylvan stockholders at the
Sylvan Annual Meeting.  Approval of the Share Issuance by Sylvan stockholders is
a condition to consummation of the Merger.  Only holders of record of Sylvan
Common Stock at the close of business on May 9, 1997 (the "Sylvan Record Date")
are entitled to notice of, and to vote at, the Sylvan Annual Meeting or any
adjournment or postponement thereof.  At the close of business on the Sylvan
Record Date, ____________ shares of Sylvan Common Stock were outstanding (the
"Sylvan Record Shares"), which constituted the only outstanding voting
securities of Sylvan.

     In the Merger, among other things, each outstanding share of NEC Common
Stock, other than NEC Common Stock held by NEC or held by Sylvan, Merger Sub or
any other wholly-owned subsidiary of Sylvan, will be converted into the right to
receive 0.58 of a share of Sylvan Common Stock (the "Initial Conversion Ratio");
provided, however, that the Initial Conversion Ratio may be adjusted upward in
the event (i) the average closing
<PAGE>
 
price of Sylvan Common Stock over a period of ten (10) trading days immediately
preceding the consummation of the Merger (the "Average Share Price") is less
than $29.86 per share (the "Trigger Price"), (ii) NEC has exercised its option
(a "Termination Option") to terminate the Merger Agreement because the Average
Share Price is less than the Trigger Price and (iii) Sylvan has elected to
exercise its option (the "Adjustment Option") to adjust the Initial Conversion
Ratio to equal the quotient of (A) the Trigger Price multiplied by the Initial
Conversion Ratio divided by (B) the Average Share Price (the "Adjusted
                 ------- --                
Conversion Ratio"). Assuming the number of shares of Sylvan Common Stock
outstanding on the Closing Date is no greater than the number of shares of
Sylvan Common Stock outstanding on March 17, 1997, Sylvan will not, in any
event, exercise its Adjustment Option to increase the Adjusted Conversion Ratio
above 0.5945. Approval of the Share Issuance by Sylvan stockholders is a
condition precedent to consummation of the Merger. Upon consummation of the
Merger, NEC will become a wholly-owned subsidiary of Sylvan. If the Sylvan
stockholders fail to approve the Share Issuance at the Sylvan Annual Meeting,
Sylvan will be required to pay NEC a $10 million termination fee unless NEC were
to otherwise give Sylvan cause to terminate the Merger.

     The Sylvan Board of Directors has carefully reviewed and considered the
terms and conditions of the proposed Merger, as well as a number of other
factors, including the opinion of Alex. Brown & Sons Incorporated ("Alex.
Brown") to the effect that, from a financial point of view, the Initial
Conversion Ratio in the Merger is fair to Sylvan.  The full text of the written
opinion of Alex. Brown, which sets forth a description of the matters
considered, assumptions made and limits on review undertaken by Alex. Brown, is
attached to the accompanying Joint Proxy Statement/Prospectus as Annex II.  The
Sylvan Board of Directors has carefully reviewed and considered the terms and
conditions of the proposed Merger, the Merger Agreement, the Share Issuance and
the other transactions contemplated thereby.  THE SYLVAN BOARD OF DIRECTORS HAS
APPROVED THE SHARE ISSUANCE PURSUANT TO THE MERGER AGREEMENT AND THE OTHER
TRANSACTIONS CONTEMPLATED THEREBY, AND RECOMMENDS THAT SYLVAN STOCKHOLDERS VOTE
FOR APPROVAL OF THE (I) SHARE ISSUANCE, (II) CHARTER AMENDMENTS AND (III) PLAN
AMENDMENTS PROPOSALS AND FOR ELECTION OF THE MERGER NOMINEES.

     THE SYLVAN BOARD OF DIRECTORS ALSO RECOMMENDS THAT SYLVAN STOCKHOLDERS VOTE
FOR (I) ELECTION OF THE CONTINGENT NOMINEES AND (II) AUDITOR CONFIRMATION
PROPOSALS.

     The accompanying Notice of Annual Meeting and Joint Proxy
Statement/Prospectus more fully describe the matters to be acted on at the
Sylvan Annual Meeting and include other information about Sylvan and NEC.

Dear Stockholder:

     You are cordially invited to attend a Special Meeting of Stockholders (the
"NEC Special Meeting") of National Education Corporation ("NEC") to be held at
10:00 am., local time, on June 25, 1997, at the ________.  At the NEC Special
Meeting, you will be asked to consider and vote upon a proposal (the "Merger
Proposal") to approve the merger of [Newco, Inc.], a Delaware corporation
("Merger Sub"), a wholly-owned subsidiary of Sylvan Learning Systems, Inc., a
Maryland corporation ("Sylvan"), with and into NEC (the "Merger") pursuant to
the Agreement and Plan of Reorganization dated as of March 12, 1997, by and
between Sylvan and NEC (the "Merger Agreement").

     In the Merger, among other things, each outstanding share of NEC Common
Stock (other than NEC Common Stock held by NEC or held by Sylvan, Merger Sub or
any other wholly-owned subsidiary of Sylvan) will be converted into the right to
receive 0.58 of a share of Sylvan Common Stock (the "Initial Conversion Ratio");
provided, however, that the Initial Conversion Ratio may be adjusted upward in
the event (i) the Average Share Price is less than the Trigger Price, (ii) NEC
has exercised its option (a "Termination Option") to terminate the Merger
Agreement because the Average Share Price is less than the Trigger Price and
(iii) Sylvan has elected to exercise its option (the "Adjustment Option") to
adjust the Initial Conversion Ratio to equal the quotient of (A) the Trigger
Price multiplied by the Initial Conversion Ratio divided by (B) the Average
                                                 ------- --               
Share Price (the "Adjusted Conversion Ratio").  Assuming the number of shares of
Sylvan Common Stock outstanding on the Closing Date is no greater than the
number of shares of Sylvan Common Stock outstanding on March 17, 1997, Sylvan
will not, in any event, exercise its Adjustment Option to increase the Adjusted
Conversion Ratio above 0.5945, a ratio above which NEC would own greater than
50% of the outstanding stock of the combined company.  Approval of the Merger
Proposal by NEC stockholders is a condition to consummation of the Merger.  Upon
consummation of the Merger, NEC will become a wholly-owned subsidiary of Sylvan.
If the NEC Stockholders do not approve the Merger Proposal at the NEC Special
Meeting, NEC will be required to pay Sylvan a $10 million termination fee unless
Sylvan were to otherwise give NEC cause to terminate the Merger.

     The NEC Board of Directors has received the written opinion of BZW, the
investment banking division of Barclays Bank PLC ("BZW") to the effect that the
consideration to be received by holders of NEC Common Stock in the Merger is
fair to stockholders of NEC other than Sylvan, Merger Sub or any other wholly-
owned subsidiary of Sylvan.  The full text of the written opinion of BZW, which
sets forth a description of the matters considered, assumptions made and limits
on review undertaken by BZW, is attached to the accompanying Joint Proxy
Statement/Prospectus as Annex III.  The Board of Directors of NEC has carefully
reviewed and considered the terms and conditions of the proposed Merger, the
Merger Agreement and the other transactions contemplated thereby.  THE NEC BOARD
OF DIRECTORS HAS APPROVED THE MERGER PURSUANT TO THE MERGER AGREEMENT AND THE
TRANSACTIONS CONTEMPLATED THEREBY, AND RECOMMENDS THAT NEC STOCKHOLDERS VOTE FOR
APPROVAL OF THE MERGER PROPOSAL.

Statement/Prospectus more fully describe the matters to be acted on at the NEC
Special Meeting and include other information about Sylvan and NEC.  Please give
this information your careful attention.

            William Pollock, Nancy A. Cole, Donald V. Berlanti and J. Phillip
            Samper (collectively, the "Merger Nominees"), to serve until the
            next Annual Meeting of Sylvan stockholders and until their
            successors are elected and qualify;

    (viii)  elect to the Sylvan Board of Directors in the event the Merger is
            terminated or the Merger Nominees are not elected, each of R.
            Christopher Hoehn-Saric, Douglas L. Becker, J. Phillip Samper,
            Donald V. Berlanti, Nancy A. Cole, James H. McGuire and R. William
            Pollock (the "Contingent Nominees" and, together with the Merger
            Nominees, the "Sylvan Board Nominees"), to serve until the next
            Annual Meeting of Sylvan stockholders and until their successors are
            elected and qualify;

      (ix)  ratify and confirm the selection of Ernst & Young LLP as Sylvan's
            independent auditors for the year ending December 31, 1997 (the
            "Auditor Confirmation"); and

       (x)  transact such other matters as may properly come before the Sylvan
            stockholders at the Sylvan Annual Meeting.

Approval of the Share Issuance by Sylvan stockholders is a condition to
consummation of the Merger.  See "PROPOSAL I:  THE SHARE ISSUANCE AND THE
MERGER--The Merger Agreement--Conditions Precedent to the Merger."  Only holders
of record of Sylvan Common Stock at the close of business on May 9, 1997 (the
"Sylvan Record Date") are entitled to notice of, and to vote at, the Sylvan
Annual Meeting or any adjournment or postponement thereof.  At the close of
business on the Sylvan Record Date, ______________ shares of Sylvan Common Stock
were outstanding, which constituted the only outstanding voting securities of
Sylvan.  See "INFORMATION CONCERNING THE SYLVAN ANNUAL MEETING."

     This Joint Proxy Statement/Prospectus also is being furnished to the
stockholders of NEC in connection with the solicitation of proxies by the NEC
Board from holders of shares of common stock, par value $.01 per share ("NEC
Common Stock"), for use at a special meeting of stockholders of NEC (the "NEC
Special Meeting," and together with the Sylvan Annual Meeting, the "Meetings")
to be held to consider and vote upon a proposal to approve the Merger, the
Merger Agreement and the transactions contemplated thereby.  UPON CONSUMMATION
OF THE MERGER, NEC WILL BECOME A WHOLLY-OWNED SUBSIDIARY OF SYLVAN.  Approval of
the Merger by NEC stockholders is a condition to consummation of the Merger.
See "PROPOSAL I:  THE SHARE ISSUANCE AND THE MERGER--The Merger
Agreement--Conditions Precedent to the Merger."  Only holders of record of NEC
Common Stock at the close of business on May 9, 1997 (the "NEC Record Date"),
are entitled to notice of, and to vote at, the NEC Special Meeting or any
adjournment or postponement thereof.  At the close of business on the NEC Record
Date, _____________ shares of NEC Common Stock were outstanding, which
constituted the only outstanding voting securities of NEC.  See "INFORMATION
CONCERNING THE NEC SPECIAL MEETING."

     In the Merger, each outstanding share of NEC Common Stock (other than NEC
Common Stock held by NEC or held by Sylvan, Merger Sub or any other wholly-owned
subsidiary of Sylvan) will be converted into the right to receive 0.58 of a
share of Sylvan Common Stock (the "Initial Conversion Ratio"); provided,
however, that 

                                      -ii-
<PAGE>
 
the Initial Conversion Ratio may be adjusted upward in the event (i) the average
closing price of Sylvan Common Stock over a period of ten (10) trading days
preceding the consummation of the Merger (the "Average Share Price") is less
than $29.86 per share (the "Trigger Price"), (ii) NEC has exercised its option
(the "Termination Option") to terminate the Merger Agreement because the Average
Share Price is less than the Trigger Price and (iii) Sylvan has elected to
exercise its option (the "Adjustment Option") to adjust the Initial Conversion
Ratio to equal the quotient of (A) the Trigger Price multiplied by the Initial
Conversion Ratio divided by (B) the Average Share Price (the "Adjusted
                 ------- --                
Conversion Ratio"). Assuming the number of shares of Sylvan Common Stock
outstanding on the Closing Date is no greater than the number of shares of
Sylvan Common Stock outstanding on March 17, 1997, Sylvan will not, in any
event, exercise its Adjustment Option to increase the Adjusted Conversion Ratio
above 0.5945. A copy of the Merger Agreement is attached to this Joint Proxy
Statement/Prospectus as Annex I and is incorporated by reference herein. See
"RISK FACTORS" BEGINNING ON PAGE 26 FOR A DISCUSSION OF CERTAIN FACTORS WHICH
SHOULD BE CONSIDERED BY THE STOCKHOLDERS OF SYLVAN AND NEC.

     In the event that either the NEC stockholders or the Sylvan stockholders do
not approve the Merger or the Share Issuance, as the case may be, the party
whose stockholders fail to approve the applicable proposal (the "Non-Approving
Party") will be required to pay a $10 million termination fee to the party whose
stockholders did approve the transaction (the "Approving Party") assuming the
Approving Party did not otherwise give the Non-Approving Party cause to
terminate the Merger Agreement.  See "PROPOSAL I:  THE SHARE ISSUANCE AND THE
MERGER--The Merger Agreement--Termination" and "--Termination Fee."

     This Joint Proxy Statement/Prospectus also constitutes the prospectus of
Sylvan with respect to the shares of Sylvan Common Stock to be issued in
exchange for all of the outstanding shares of NEC Common Stock in connection
with the Merger, as described herein.  Sylvan Common Stock is listed and traded
on the Nasdaq National Market ("Nasdaq") under the symbol "SLVN".  NEC Common
Stock is listed and traded on the New York Stock Exchange ("NYSE") and the
Pacific Stock Exchange ("PSE") under the symbol "NEC".  This Joint Proxy
Statement/Prospectus and the accompanying forms of proxy are first being sent to
holders of Sylvan Common Stock and NEC Common Stock on or about May 20, 1997.

                           FORWARD-LOOKING STATEMENTS

     Certain statements in the Summary and under the captions "RISK FACTORS,"
"PROPOSAL I:  THE SHARE ISSUANCE AND THE MERGER--Reasons of Sylvan for the
Merger; Recommendations of the Sylvan Board," "--Reasons of NEC for the Merger;
Recommendations of the NEC Board" and "HISTORICAL AND PRO FORMA COMBINED
SELECTED FINANCIAL INFORMATION" elsewhere in this Joint Proxy
Statement/Prospectus, constitute "forward-looking statements" within the meaning
of the Private Securities Litigation Reform Act of 1995.  Such forward-looking
statements involve known and unknown risks, uncertainties and other factors
which may cause the actual results, performance, or achievements of the combined
company to be materially different from any future results, performance or
achievements expressed or implied by such forward-looking statements.  These
forward-looking statements were based on various factors and were derived
utilizing numerous important assumptions and other important factors that could
cause actual results to differ materially from those in the forward-looking
statements.  Important assumptions and other important factors that could cause
actual results to differ materially from those in the forward-looking statements
include, but are not limited to: uncertainty as to the combined company's future
profitability; the combined company's ability to develop and implement
operational and financial systems to manage rapidly growing operations;
competition in Sylvan's and NEC's existing and potential future lines of
business; the combined company's ability to integrate and successfully operate
acquired businesses and the risks associated with such businesses; the combined
company's ability to obtain financing on acceptable terms to finance the
combined company's growth strategy and for the combined company to operate
within the limitations imposed by financing arrangements; uncertainty as to the
future profitability of acquired businesses; trends in the education services
market; competitive pressures; new product development and technological change;
changes in relationships with customers, academic institutions or other business
associates; changes in the regulatory environment; outcome of pending litigation
and regulatory inquiries; and the impact of accounting policies required to be
adopted in the near future.  Other factors and assumptions not identified above
were also involved in the derivation of these forward-looking statements, and
the failure of such other assumptions to be realized as well as other factors
may also cause actual results to differ materially from those projected.
Neither Sylvan nor NEC assume any obligation to update these forward-looking
statements to reflect actual results, changes in assumptions or changes in other
factors affecting such forward-looking statements.

                                    SUMMARY

     The following is a summary of certain information contained elsewhere in
this Joint Proxy Statement/Prospectus. This summary is not intended to be
complete and reference is made to, and this summary is qualified in its entirety
by, the more detailed information contained in this Joint Proxy
Statement/Prospectus, the Annexes hereto and the documents incorporated herein
by reference. Stockholders of both Sylvan and NEC are encouraged to review
carefully this Joint Proxy Statement/Prospectus and the Annexes hereto, and the
documents incorporated herein by reference, in their entirety. On September 27,
1996, the Sylvan Board of Directors declared a three-for-two stock split in the
form of a stock dividend to stockholders of record on October 7, 1996, which was
distributed on November 7, 1996 (the "Sylvan Stock Split"). All references in
this Joint Proxy Statement/Prospectus to historical share and per share data for
Sylvan have been retroactively adjusted to reflect the Sylvan Stock Split.
Capitalized terms used in this Summary and not defined shall have the meanings
ascribed to them elsewhere in this Joint Proxy Statement/Prospectus.

THE MERGER AND THE COMPANIES

     THE MERGER

     Under the terms of the Merger Agreement, Sylvan will acquire NEC in a 
stock-for-stock transaction to be accounted for as a pooling-of-interests.
Sylvan will issue 0.58 shares of its Common Stock for each share of NEC Common
Stock outstanding (the "Initial Conversion Ratio"); provided, however, that if
the Average Share Price is less than $29.86 per share, each of NEC and Sylvan
can exercise an option (the "Termination Option") to terminate the Merger
Agreement and the Merger; and provided, further, that should NEC exercise its
Termination Option, Sylvan can exercise an option (the "Adjustment Option") to
force NEC to revoke the exercise of its Termination Option if Sylvan increases
the Initial Conversion Ratio to the Adjusted Conversion Ratio. For example, if
the Average Share Price is $29.13 ($____ higher than the per share closing price
of the Sylvan Common Stock on the trading day preceding the date of this Joint
Proxy Statement/Prospectus), the Adjusted Conversion Ratio would be 0.5945.
Assuming that the number of shares of Sylvan Common Stock outstanding on the
Closing Date equals the number of shares of Sylvan Common Stock outstanding on
March 17, 1997, Sylvan will not, in any event, increase the Adjusted Conversion
Ratio above 0.5945. Assuming the Initial Conversion Ratio is used, following the
Merger, stockholders of NEC would hold approximately 46% of the outstanding
common stock of Sylvan. The Merger Agreement contemplates that the Sylvan Board
of Directors following the Merger would be comprised of 10 persons, including
Messrs. Douglas L. Becker and R. Christopher Hoehn-Saric, the current Co-Chief
Executive Officers of Sylvan, Mr. Sam Yau, the current Chief Executive Officer
of NEC, three additional NEC directors and four other current members of the
Sylvan Board of Directors. See "PROPOSALS VII AND VIII: ELECTIONS OF SYLVAN
BOARD NOMINEES."

REASONS FOR THE MERGER

     After consulting with management and its advisors and considering various
factors, each of the Sylvan Board of Directors and the NEC Board of Directors

and strengths of Sylvan and NEC will enhance the competitive position of, offer
potential cost savings and opportunities for other synergies to, and provide a
platform for continued growth, both internally and through acquisitions, for the
combined company. See "PROPOSAL I: THE SHARE ISSUANCE AND THE MERGER--Reasons of

______________
(1)  The pro forma statement of operations of Sylvan for the year ended December
     31, 1996 includes the pro forma effects of the acquisition of Wall Street
     Institute Group ("WSI"). WSI was acquired by Sylvan on December 1, 1996 in
     a transaction accounted for as a purchase. See the Current Report on Form 
     8-K/A of Sylvan dated April 10, 1997 and incorporated herein by reference
     in this Joint Proxy/Prospectus.

(2)  Pro forma combined earnings (loss) per share amounts are based on the
     weighted average number of shares assumed to be outstanding during the
     period, adjusted to give effect to the issuance of approximately 20.7
     million shares of Sylvan Common Stock constituting the Share Issuance and
     the conversion of other outstanding dilutive securities using the Initial
     Conversion Ratio. In computing earnings per share in 1996, pro forma net
     income is reduced by the estimated additional amortization that would
     result from the payment of certain contingent consideration related to the
     acquisition by Sylvan of PACE in 1995, as discussed in Note 6 to the
     Unaudited Pro Forma Condensed Combined Financial Statements.

(3)  As discussed further in the introduction to Unaudited Pro Forma Condensed
     Combined Financial Statements, the pro forma condensed combined balance
     sheet includes, in accordance with the Commission's reporting rules, the
     estimated effects of events that are directly attributable to the Merger.
     Therefore, the pro forma condensed combined balance sheet reflects a pro
     forma adjustment, net of related taxes, of $43.3 million, for the estimated
     amount of transaction costs, termination benefits, and restructuring
     charges, as discussed in Note 1 to the Unaudited Pro Forma Condensed
     Combined Financial Statements.

THE MERGER

     General.  If the Sylvan stockholders approve the Share Issuance and the NEC
stockholders approve the terms of the Merger Agreement, including the Merger,
and all other conditions to the Merger are satisfied or waived, Merger Sub will
be merged with and into NEC, with NEC being the surviving corporation after the
Merger (the "Surviving Corporation") and becoming a wholly-owned subsidiary of
Sylvan, effective at the time the Certificate of Merger is filed with the
Secretary of State of the State of Delaware (the "Effective Time").

     Upon consummation of the Merger pursuant to the Merger Agreement, each
outstanding share of NEC Common Stock, other than NEC Common Stock held by NEC
or held by Sylvan, Merger Sub or any other wholly-owned subsidiary of Sylvan,
will be converted into the right to receive 0.58 of a share of Sylvan Common
Stock (the "Initial Conversion Ratio"); provided, however, that the Initial
Conversion Ratio may be increased to the Adjusted Conversion Ratio if (i) the
Average Share Price is less than the Trigger Price, (ii) NEC has exercised its
Termination Option and (iii) Sylvan has exercised its Adjustment Option. An
Average Share Price of $29.13 ($___ higher than the per share closing price of
the Sylvan Common Stock on the trading day immediately preceding the printing of
this Joint Proxy Statement/Prospectus) would yield an Adjusted Conversion Ratio
of 0.5945, resulting in the issuance by Sylvan of an aggregate of ______ shares
of Sylvan Common Stock to the holders of NEC Common Stock outstanding on the
Record Date. Assuming the number of shares of Sylvan Common Stock outstanding on
the Closing Date is no greater than the number of shares of Common Stock
outstanding on March 17, 1996, Sylvan will not, in any event, exercise its
Adjustment Option if the Average Share Price is below $29.13. See "PROPOSAL I:
THE SHARE ISSUANCE AND THE MERGER--The Merger Agreement--Conversion of Shares."

     ALTHOUGH THE INITIAL CONVERSION RATIO MAY BE INCREASED DEPENDING ON THE
EXTENT THE AVERAGE SHARE PRICE IS LESS THAN $29.86, THE MARKET PRICE OF SYLVAN
COMMON STOCK MAY FLUCTUATE AND, ON THE CLOSING DATE, THE DATE SHARES OF SYLVAN
COMMON STOCK ARE RECEIVED BY HOLDERS OF NEC COMMON STOCK, OR THE DATE ON WHICH
SUCH SHARES OF SYLVAN COMMON STOCK ARE EVENTUALLY SOLD, MAY BE MORE OR LESS THAN
THE PRICE OF SYLVAN COMMON STOCK AS OF THE DATE OF THIS JOINT PROXY
STATEMENT/PROSPECTUS.

     In lieu of any fractional shares of Sylvan Common Stock, each holder of NEC
Common Stock who otherwise would be entitled to receive a fractional share of
Sylvan Common Stock will be paid an amount in cash equal to the Average Share
Price of Sylvan Common Stock as of _____________ multiplied by the fractional
share interest to which such NEC stockholder is entitled. See "PROPOSAL I: THE
SHARE ISSUANCE AND THE MERGER--The Merger Agreement--Exchange Procedures."

     Background of the Merger. For information concerning the background of the
Merger, see "PROPOSAL I: THE SHARE ISSUANCE AND THE MERGER--Background of the
Merger."

     Recommendations of the Sylvan Board of Directors.  The Sylvan Board of
Directors has unanimously concluded that the terms of the Merger Agreement,
including the Merger and the Share Issuance, are fair to, and in the best
interests of, Sylvan and its stockholders and unanimously recommends that Sylvan
stockholders vote FOR approval of the Share Issuance. For a discussion of the
factors considered by the Sylvan Board of Directors in reaching its decision to
approve and recommend to Sylvan stockholders the Share Issuance, see "PROPOSAL
I: THE SHARE ISSUANCE AND THE MERGER--Reasons of Sylvan for the Merger;
Recommendation of the Sylvan Board."

Brown") acted as financial advisor to Sylvan in connection with the Merger. On

Initial Conversion Ratio in the Merger is fair to Sylvan. Alex. Brown
subsequently confirmed its earlier opinion by delivery of its written opinion
dated as of March 12, 1997. A copy of the written opinion of Alex. Brown, which
sets forth a discussion of the assumptions made, matters considered and
limitations on the review undertaken by Alex. Brown, is attached hereto as Annex
II and is incorporated herein by reference. See "PROPOSAL I: THE SHARE ISSUANCE
AND THE MERGER--Sylvan Financial Advisor."

     Recommendations of the NEC Board. The NEC Board has unanimously concluded
that the Merger is advisable and in the best interests of NEC and its
stockholders and unanimously recommends that NEC stockholders vote FOR approval
of the Merger Proposal. See "PROPOSAL I: THE SHARE ISSUANCE AND THE
MERGER--Reasons of NEC for the Merger; Recommendation of the NEC Board."

     Financial Advisors to NEC. BZW, the investment banking division of Barclays
Bank PLC ("BZW"), acted as financial advisor to NEC in connection with NEC's
consideration of the Merger, the Merger Agreement and the other transactions
contemplated thereby. On March 11, 1997, BZW delivered its oral opinion to the
NEC Board that as of the date of such opinion, the Initial Conversion Ratio
pursuant to the Merger Agreement was fair to the holders of NEC Stock other than
Sylvan, Merger Sub or any other wholly-owned subsidiary of Sylvan. BZW
subsequently confirmed its earlier opinion by delivery of its written opinion
dated as of March 12, 1997.

     The full text of the written opinion of BZW, which sets forth assumptions
made, matters considered and limitations on the review undertaken in connection
with the opinion is attached hereto as Annex III and is incorporated herein by
reference. Holders of NEC Common Stock are urged to, and should, read such
opinion in its entirety. See "PROPOSAL I: THE SHARE ISSUANCE AND THE MERGER--NEC
Financial Advisor."

     Conditions to the Merger. The obligations of Sylvan and NEC to consummate
the Merger are subject to the satisfaction or waiver (where permissible) of
various conditions, including, among others, (i) approval of the Share Issuance
by the holders of the outstanding shares of Sylvan Common Stock and approval of
the Merger Proposal by the holders of the outstanding shares of NEC Common
Stock, each by the requisite vote under applicable law, (ii) receipt by Sylvan
of a letter from Ernst & Young LLP, its independent auditors, and receipt by NEC
of a letter from Price Waterhouse LLP, its independent accountants, each to the
effect that subject to customary qualifications, no event has occurred with
respect to Sylvan or NEC, as applicable, which would preclude the Merger from
being treated as a pooling-of-interests under Accounting Principles Board
Opinion No. 16 (in each case, a "Pooling Letter"), (iii) receipt by Sylvan and
NEC of opinions of their respective tax counsel to the effect that, inter alia,
on the basis of representations made by Sylvan and NEC and referred to therein,
for U.S. federal income tax purposes, the Merger will qualify as a tax-free
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986, as amended (the "Code"), and that Sylvan, Merger Sub and NEC will each
be a party to the reorganization and (iv) certain other conditions. See
"PROPOSAL I: THE SHARE ISSUANCE AND THE MERGER--The Merger Agreement--Conditions
Precedent to the Merger."

     Termination of the Merger Agreement. The Merger Agreement may be terminated
by Sylvan or NEC under certain circumstances, including either Sylvan's or NEC's
exercise of the Termination Option; provided, however, that Sylvan can prevent
termination after NEC has exercised the Termination Option if Sylvan elects to
exercise its Adjustment Option. If the Merger is terminated due to a material
breach of the Merger Agreement or failure to obtain stockholder approval by
either Sylvan or NEC, the breaching or non-approving party may be required to
pay to the other a termination fee of $10,000,000 assuming the non-breaching or
approving party did not otherwise give the non-approving party cause to
terminate the Merger Agreement. Under certain other circumstances, NEC may be
required to pay Sylvan an additional amount of liquidated damages of
$20,000,000, or an aggregate termination fee of $30,000,000. See "PROPOSAL I:
THE SHARE ISSUANCE AND THE MERGER--The Merger Agreement--Termination" and
"--Termination Fee."

     Regulatory Matters. Under the Hart-Scott-Rodino Antitrust Improvements Act
of 1976, as amended, (the "HSR Act"), and the rules that have been promulgated
thereunder by the Federal Trade Commission ("FTC"), the Merger may not be
consummated unless certain filings have been submitted to the Antitrust Division
of the United States Department of Justice (the "Antitrust Division") and the
FTC and certain waiting period requirements have been satisfied. On March 26,
1997, Sylvan and NEC submitted the required filings to the FTC and the Antitrust
Division relating to the Merger. On April __, 1997, Richard C. Blum, a Director
of NEC and an affiliate of a principal stockholder of NEC ("Blum"), submitted
the required filings to the FTC and the Antitrust Division relating to Blum's
acquisition of more than $15 million of Sylvan Common Stock in the proposed
Merger. On April 25, 1997 and May __, 1997, the respective waiting periods under
the HSR Act expired. See "PROPOSAL I: THE SHARE ISSUANCE AND THE MERGER--
Regulatory Matters."

     Certain Federal Income Tax Consequences. Each of Sylvan and NEC has
received an opinion from its tax counsel to the effect that, among other things,
the Merger will constitute a "reorganization" within the meaning of Section
368(a) of the Code and no gain or loss will be recognized by the stockholders of
NEC upon the exchange of their shares of NEC Common Stock solely for shares of
Sylvan Common Stock pursuant to the Merger, except with respect to cash, if any,
received in lieu of fractional shares of Sylvan Common Stock. It is a condition
to the consummation of the Merger that each such opinion of tax counsel be
confirmed on and as of the Closing Date. NEC stockholders are urged to consult
their own tax advisors as to the specific tax consequences of the Merger. See
"PROPOSAL I: THE SHARE ISSUANCE AND THE MERGER--Certain Federal Income Tax
Consequences" and "PROPOSAL I: THE SHARE ISSUANCE AND THE MERGER--The Merger
Agreement--Conditions Precedent to the Merger."

     Accounting Treatment. It is intended that the Merger will be accounted for
as a pooling-of-interests under generally accepted accounting principles.
Consummation of the Merger is conditioned upon receipt by each of Sylvan and NEC
of a Pooling Letter from its independent auditors. See "PROPOSAL I: THE SHARE
ISSUANCE AND THE MERGER--Accounting Treatment."

     Appraisal Rights. Under the Delaware General Corporation Law ("DGCL"), the
holders of NEC Common Stock will not have dissenters' appraisal rights in
connection with the Merger Agreement and the consummation of the Merger. Under
the Maryland General Corporation Law ("MGCL"), the holders of Sylvan Common
Stock will not have objecting stockholders' appraisal rights in connection with
the Share Issuance and the consummation of the Merger. See "PROPOSAL I: THE
SHARE ISSUANCE AND THE MERGER--Appraisal Rights" and "PROPOSAL I: THE SHARE
ISSUANCE AND THE MERGER--Comparative Rights of Stockholders of Sylvan and
NEC--Appraisal Rights."

     Interests of Certain Persons in the Merger. Stockholders of NEC should be
aware that certain directors and officers of NEC have interests in the Merger
that are in addition to and potentially in conflict with the interests of
stockholders of NEC. See "PROPOSAL I: THE SHARE ISSUANCE AND THE MERGER--
Interests of Certain Persons in the Merger" and "PROPOSALS VII AND VIII:
ELECTIONS OF SYLVAN BOARD NOMINEES--Merger Nominees."

     Comparative Rights of Stockholders of Sylvan and NEC. As a result of the
Merger, shares of NEC Common Stock, which are issued by a Delaware corporation,
will be converted into the right to receive shares of Sylvan Common Stock, which
are issued by a Maryland corporation. There are differences between the rights
of NEC stockholders and the rights of Sylvan stockholders. These differences
result from (i) differences between the MGCL and the DGCL and (ii) differences
between the governing instruments of NEC and Sylvan. For a discussion of certain
differences between the rights of NEC stockholders and the rights of Sylvan
stockholders, see "PROPOSAL I: THE SHARE ISSUANCE AND THE MERGER--Comparative
Rights of Stockholders of Sylvan and NEC."

CHARTER AMENDMENTS

     At the Sylvan Annual Meeting, Sylvan stockholders will be asked to consider
and vote upon proposals to amend Sylvan's Charter to (i) reduce the term served
by Sylvan directors from three years to one year and to eliminate separate
classes of Sylvan directors (the "Directors Amendment"), (ii) increase from
40,000,000 to 90,000,000 the number of authorized shares of Sylvan Common Stock
(the "Common Shares Amendment") and (iii) increase from 250,000 to 400,000 the
number of shares of Preferred Stock of Sylvan, $.01 par value per share, which
are designated as Junior Participating Preferred Stock (the "Preferred Shares
Amendment" and, together with the Directors Amendment and the Common Shares
Amendment, the "Charter Amendments"). Stockholders of Sylvan should carefully
evaluate the matters set forth under "PROPOSALS II, III AND IV: CHARTER
AMENDMENTS."

PLAN AMENDMENTS

    At the Sylvan Annual Meeting, Sylvan stockholders will be asked to consider
and vote upon proposals to amend (i) the 1993 Plan to provide for an increase of
2,575,000 shares in the total number of shares of Sylvan Common Stock currently
authorized for issuance under the 1993 Plan and (ii) the Management Plan to
provide for an increase of 1,000,000 shares in the total number of shares of
Sylvan Common Stock currently authorized for issuance under the Management Plan.
Approval of each of the Plan Amendments would increase to 5,200,000 and
3,250,000 the total number of shares authorized for issuance under the 1993 Plan
and the Management Plan, respectively. As of April 1, 1997, 129,597 shares and
1,215,000 shares remained available for grant pursuant to the 1993 Plan and the
Management Plan, respectively. Stockholders of Sylvan should carefully evaluate
the matters set forth under "PROPOSALS V AND VI: PLAN AMENDMENTS."

SYLVAN BOARD NOMINEES

     At the Sylvan Annual Meeting, Sylvan stockholders will be asked to consider
and vote upon proposals to elect the Merger Nominees, with such elections to
become effective upon consummation of the Merger, and to elect to the Sylvan
Board of Directors the Contingent Nominees in the event the Merger is terminated
or the Merger Nominees are not elected at the Sylvan Annual Meeting.
Stockholders of Sylvan should carefully evaluate the matters set forth under
"PROPOSAL FOR PLAN AMENDMENTS" and "PROPOSALS VII AND VIII: ELECTIONS OF SYLVAN
BOARD NOMINEES."

                                 RECENT EVENTS

Sylvan's Agreement to Acquire Inroads

         On April 17, 1997, Sylvan entered into a definitive agreement to 
acquire 100% of the stock of I-R, Inc. and Independent Child Study Teams, Inc. 
(collectively "Inroads") in two merger transactions that would be accounted for 
as poolings-of-interests. Inroads, which is privately held, had revenues of 
approximately $24 million in 1996. To consummate the transaction, Sylvan will 
issue approximately 1.4 million shares of Common Stock. The transaction is 
expected to close by the end of May 1997. If the average price of Sylvan's 
Common Stock is less than $22 for the 15 trading days prior to closing, Sylvan 
may either adjust the number of shares issuable to equal $31.1 million in then 
market value or terminate the agreement.

         Inroads provides remedial educational services to non-public school
systems, funded by the Federal Title I program and similar state funded
programs. Inroads has school contracts in New Jersey, Maryland, Louisiana, and
Washington, D.C., among others.

Harcourt Tender Offer Announcement for NEC Common Stock

         On April 16, 1997, Harcourt General, Inc. ("Harcourt") announced that 
it would commence an all-cash tender offer for all of the outstanding NEC Common
Stock at a price of $19.50 per share. Harcourt indicated that its offer has a 
total transaction value of approximately $740 million. Harcourt also announced 
that the tender offer will be subject to customary conditions and the 
termination of the Merger Agreement but is not subject to any financing 
contingencies. The complete terms and conditions of the tender offer are 
expected to be set forth in offering documents which will be filed by Harcourt 
with the Securities and Exchange Commission. Harcourt further stated that it 
intends to effect a merger in which holders of all shares of NEC Common Stock 
that are not tendered would receive the same cash price paid in the tender 
offer.

         Harcourt also announced its intention, subject to its ability to 
effectuate a merger with NEC, to seek to acquire the outstanding shares of 
common stock of Steck-Vaughn Publishing Corporation ("SVPC") not currently owned
by NEC at a price per share of $14.00. Harcourt, however, did not disclose the
manner by which it would seek to acquire the SVPC shares or the timing of any
such acquisition.

(1)  Prior to February 1, 1991, the Sylvan Learning Centers business was
     conducted by Sylvan Learning Corporation (the "Predecessor"). On February
     1, 1991, the Predecessor contributed the Sylvan Learning Centers business
     to Sylvan KEE Systems, a Maryland general partnership (the "Partnership")
     in exchange for a 50% partnership interest, and Sylvan contributed its
     computer training software development business to the Partnership in
     exchange for the other 50% partnership interest. On January 26, 1993,
     Sylvan acquired the Predecessor and dissolved the Partnership. On September
     3, 1993, Sylvan sold its computer training software development business.

     During 1994, Sylvan acquired by merger all of the outstanding stock of
     Learning Services, Inc. ("LSI") and all of the outstanding stock of Loralex
     Corporation ("Loralex"). These companies owned and operated a total of nine
     Sylvan Learning Centers located in the Northeast United States and Florida.

     On February 17, 1995, Sylvan acquired by merger all of the outstanding
     stock of Remedial Education and Diagnostic Services, Inc. and READS, Inc.
     (collectively, "READS"). READS is based in Philadelphia, Pennsylvania and
     provides remedial and education services, psychological, diagnostic and
     counseling services, career awareness training, and a variety of consulting
     services. Services are delivered under contracts with school districts,
     county-wide educational agencies and municipalities in the Eastern United
     States.

     The READS, Loralex and LSI acquisitions have been accounted for by Sylvan
     as poolings-of-interests and, accordingly, Sylvan's financial statements
     have been restated for all periods presented to include the results of
     operations of READS, LSI and Loralex.

(2)  All share and per share data have been restated to retroactively reflect a
     3-for-2 stock split of the Sylvan Common Stock effected at the close of
     business on November 7, 1996.

(3)  Sylvan has reclassified certain operating expenses previously included in
     general and administrative expense to division-specific expense categories.
     This change has been reflected for all periods presented.

(4)  Represents Sylvan's computer training software development business which
     was sold in September 1993 and a Canadian computer training business, 80.1%
     of which was sold in 1992.

(5)  Represents the $350,000 gain on extinguishment of a $3.5 million debt to
     Learning Centers, Inc., and a $527,000 loss on an extinguishment of $5.0
     million of notes payable to stockholders.

(6)  On December 1, 1996, Sylvan acquired Wall Street Institute Group ("WSI") in
     a transaction accounted for as a purchase. For information regarding the
     pro forma effects of this transaction on the 1996 Statement of Operations
     of Sylvan, see Sylvan's Current Report on Form 8-K/A dated April 10, 1997,
     incorporated by reference herein.

(2)  Represents the adoption by NEC in 1994 of a new accounting pronouncement at
     ICS Learning Systems, Inc. which resulted in the amortization of the
     deferred marketing balance as of December 31, 1993 into 1994 of
     $19,836,000, and a charge of $7,574,000 resulting from increased selling
     and marketing spending above the amortization that would have been expensed
     in accordance with NEC's previous accounting policy. The remaining deferred
     marketing balance at December 31, 1994 was amortized in 1995.

(3)  Represents the write-off of in-process research and development due to the
     acquisition of Edunetics by Steck-Vaughn Publishing Corporation ("SVPC") in

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

     The following unaudited pro forma condensed combined financial statements
are presented to reflect the estimated impact on the historical consolidated
financial statements of Sylvan of the Merger and the issuance of approximately
20.7 million shares of Sylvan Common Stock based on the Initial Conversion Ratio
multiplied by the 35,647,483 shares of NEC Common Stock outstanding as of March
31, 1997, constituting the Share Issuance. The Merger will be accounted for as a
pooling-of-interests.

     The unaudited pro forma condensed combined statements of operations for
each of the three years in the period ended December 31, 1996 and for the three
month periods ended March 31, 1996 and 1997 assume that the Merger had been
consummated at the beginning of the earliest year presented (January 1, 1994).
The unaudited pro forma condensed combined statements of operations for the year
ended December 31, 1996 and the three months ended March 31, 1996 also give
effect to Sylvan's acquisition of Wall Street Institute Group on December 1,
1996 as if this acquisition, which was accounted for as a purchase, occurred on
January 1, 1996. The pro forma condensed combined balance sheet at December 31,
1996 assumes that the Merger had been consummated on December 31, 1996.

     The pro forma condensed combined statements of operations include pro forma
adjustments that give effect to factually supportable recurring reductions of
expenses resulting from the consolidation of operations of the combining
companies. These pro forma condensed combined statements of operations exclude
(i) the positive effects of potential increased revenues or operating synergies
and cost savings which may be achieved upon combining the resources of the
companies, (ii) investment banking, legal, and miscellaneous transaction costs
of the Merger, currently estimated to be $10.8 million on a pre-tax and after-
tax basis, (iii) costs associated with termination benefits of certain employees
and directors of NEC, currently estimated to be $8.7 million on a pre-tax basis
and $5.2 million on an after-tax basis, and (iv) costs associated with the
consolidation and restructuring of combined operations, currently estimated to
be $40.8 million on a pre-tax basis and $27.3 million on an after-tax basis. The
total charges of $60.3 million ($43.3 million after-tax) for these non-recurring
items directly attributable to the Merger will be recorded in the quarter in
which the Merger is consummated, which is expected to occur in the second
quarter of 1997.

     The pro forma condensed combined balance sheet at December 31, 1996
includes, in accordance with the Commission's reporting rules, the estimated
effects of events that are directly attributable to the Merger, whether of a
recurring or non-recurring nature, that can be reasonably estimated and are
factually supportable. Therefore, the pro forma condensed combined balance sheet
reflects a pro forma adjustment, net of related taxes, of $43.3 million, for the
estimated amounts of transaction costs, termination benefits, and restructuring
charges, as discussed above.

     The historical statement of operations classifications for Sylvan and NEC
have been reclassified to present the expected classifications upon consummation
of the Merger. Sylvan's revenues have primarily been service related
(educational and testing), while NEC's revenues are primarily related to
education and training contracts which include the offering of training
materials and related support services and supplemental educational products.
Sylvan does not expect any material adjustments of historical financial
statements from conforming accounting policies of Sylvan and NEC.

     The unaudited pro forma condensed combined financial statements are based
on the estimates and assumptions set forth in the notes to such statements. The
pro forma adjustments made in connection with the development of the pro forma
information are preliminary and have been made solely for purposes of developing
the pro forma information necessary to comply with the disclosure requirements
of the Commission. The unaudited pro forma condensed combined financial
statements do not purport to be indicative of the consolidated results of
operations of future periods or the consolidated financial position or the
results that actually would have been reported had Sylvan and NEC been a single
entity during the periods presented. Further, there can be no assurance that
Sylvan will not incur non-recurring charges in excess of the $43.3 million of
after-tax charges currently estimated, as discussed above.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

(1) Merger-Related Non-Recurring Charges. In connection with the acquisition of
    ------------------------------------
    NEC, Sylvan expects to incur certain non-recurring charges of $60.3 million,
    with an after-tax effect of $43.3 million. These charges include estimated
    transaction costs of Sylvan and NEC of $10.8 million pre-tax and after-tax,
    costs associated with termination benefits of certain employees and
    directors of NEC of $8.7 million pre-tax and $5.2 million after-tax, and
    costs associated with the consolidation and restructuring of combined
    operations of $40.8 million pre-tax and $27.3 million after tax.

    Consolidation and restructuring charges consist of asset impairment charges
    and estimated obligations resulting from the Merger. Impairment charges
    relate primarily to inventory, property and equipment, goodwill, and
    deferred contract costs. A pre-tax impairment of inventory, property and
    equipment and other assets of $6.8 million is expected to result from the
    loss from abandonment or sale of certain inventory, equipment, leasehold
    improvements, capitalized internal use software, and other assets of Sylvan
    and NEC. Sylvan expects to write-down goodwill by approximately $15.0
    million to record impairments related to certain businesses that are
    expected to be restructured as a result of the Merger. Sylvan also expects,
    as a result of the Merger, to renegotiate or cancel certain contracts with
    non-affiliated computer-based testing centers for which advance payments of
    $10.0 million were recorded as deferred contract costs at December 31, 1996.

    Sylvan also expects to incur pre-tax obligations of $9.0 million related to
    lease and contract terminations and payments to certain franchisees for
    potential infringement of franchise rights as a result of the Merger.

    The pre-tax amount of all estimated non-recurring charges of $60.3 million
    was reduced by the estimated tax effect of $17.0 million. The tax effect was
    determined by estimating the effective tax rate associated with these
    charges at the consummation date.

(2) Pooling Adjustment.  Adjustment to properly reflect the par value of
    ------------------                                                  
    outstanding shares after the Merger.

(3) Sylvan 1996 Pro Forma Statement of Operations.  The statement of operations
    ---------------------------------------------                              
    of Sylvan for the year ended December 31, 1996 includes the pro forma
    effects of the acquisition of Wall Street Institute Group ("WSI").  WSI was
    acquired by Sylvan on December 1, 1996 in a transaction accounted for as a
    purchase.  See the Current Report on Form 8-K/A of Sylvan dated April 10,
    1997 and incorporated by reference in this Joint Proxy Statement/Prospectus.

(4) Compensation and Facility Cost Adjustments.  Upon the consummation of the
    ------------------------------------------                               
    merger, Sylvan will terminate certain identified employees of NEC and close
    NEC's corporate headquarters in Irvine, California.  These factually
    supportable  expense reductions will be offset by expense increases caused
    by the relocation of certain functions to Sylvan's headquarters in
    Baltimore, Maryland.  The pro forma adjustments adjust the statement of
    operations for the estimated effects of these actions as if they occurred on
    January 1, 1994.

(5) Income Taxes.  All pro forma adjustments relate to expenses incurred by NEC.
    ------------
    Accordingly, the provision for income taxes has been adjusted for the
    estimated effect of pro forma adjustments using the 1996 effective rate of
    NEC of approximately 10%.  This effective rate is substantially lower than
    the federal statutory tax rate of 34% due primarily to the existence of
    significant operating loss carry forwards and related valuation allowances.
    See the 1996 Annual Report on Form 10-K of NEC incorporated by reference
    herein.

(6) Earnings (Loss) Per Share.  Pro forma combined earnings (loss) per share
    --------------------------                                              
    amounts are based on the weighted average number of shares assumed to be
    outstanding during the period, adjusted to give effect to the Share Issuance
    and the conversion of other outstanding dilutive securities using the
    Initial Conversion Ratio.  In computing earnings (loss) per share in 1995
    and 1996, pro forma net income (loss) is reduced by the estimated additional
    amortization that would result from the payment of certain contingent
    consideration to the former shareholders of PACE, acquired by Sylvan in
    1995.  See the 1996 Annual Report on Form 10-K of Sylvan incorporated by
    reference herein.

and book value for NEC on an unaudited per share equivalent pro forma basis.
Pro forma combined earnings per share is derived from the pro forma condensed
combined financial statements presented elsewhere herein, which gives effect to
the Merger on the pooling of interests accounting method as if the Merger had
occurred on January 1, 1994 and combines the results of NEC and Sylvan for each
of the periods presented. The equivalent pro forma combined per NEC share data
is calculated by multiplying the pro forma combined per Sylvan share amounts by
the Initial Conversion Ratio of 0.58:1.0. Book value per share has been adjusted
to include the shares of Sylvan Common Stock to be issued in the Merger, and
assumes that the Merger had been effective at the end of the period presented.
The information set forth below should be read in conjunction with the
consolidated financial statements of NEC and Sylvan incorporated by referenced
in this Joint Proxy Statement/Prospectus and the "Unaudited Pro Forma Condensed
Combined Financial Statements," in each case including the notes thereto. The
pro forma information presented herein is for illustrative purposes only and
does not purport to be indicative of the consolidated results of operations of
future periods, the consolidated financial position or the results that would
have actually been reported had Sylvan and NEC been a single entity during the
periods presented.

(1) The historical book value per share is computed by dividing shareholders'
    equity by the number of shares of common stock outstanding at the end of the
    respective period.

(2) The pro forma statement of operations of Sylvan for the year ended December
    31,1996 includes the pro forma effects of Wall Street Institute Group
    ("WSI").  WSI was acquired by Sylvan on December 1, 1996 in a transaction
    accounted for as a purchase.  See the Current Report on Form 8-K/A of Sylvan
    dated April 10, 1997 and incorporated herein by reference in this Joint
    Proxy Statement/Prospectus.

(3) Pro forma combined earnings (loss) per share amounts are based on the
    weighted average number of shares assumed to be outstanding during the
    period, adjusted to give effect to the Share Issuance and the conversion of
    other outstanding dilutive securities using the Initial Conversion Ratio.

    in 1995 and 1996, pro forma net income (loss) is reduced by the estimated
    additional amortization that would result from the payment of certain
    contingent consideration as discussed in Note 6 to the Unaudited Pro Forma
    Condensed Combined Financial Statements.

(4) As discussed further in the introduction to Unaudited Pro Forma Condensed
    Combined Financial Statements, the pro forma condensed combined balance
    sheet includes, in accordance with the Commission's reporting rules, the
    estimated effects of events that are directly attributable to the Merger.
    Therefore, the pro forma condensed combined balance sheet reflects a pro
    forma adjustment, net of related taxes, of $43.3 million, for the estimated
    amounts of transaction costs, termination benefits, and restructuring
    charges, as discussed in Note 1 to the Unaudited Pro Forma Condensed
    Combined Financial Statements. The pro forma book value per share is
    computed by dividing pro forma stockholders' equity, including the effects
    of these adjustments, by the pro forma number of shares of common stock
    outstanding at the end of each period.

(5) The equivalent pro forma combined NEC share amounts are calculated by
    multiplying the pro forma combined per Sylvan share by the Initial
    Conversion Ratio of 0.5800 share of NEC Common Stock for each share of
    Sylvan Common Stock.

________________
(a)  Price information on Sylvan Common Stock reflects the impact of the Sylvan
     Stock Split.

     On March 11, 1997, the last trading day before the announcement of the
Merger Agreement, the last reported per share sales price of the Sylvan Common
Stock as reported on Nasdaq and the NEC Common Stock as reported on the NYSE
Composite Tape was $35.125 and $17.125 per share, respectively. Assuming the NEC
Special Meeting and the Merger had occurred on such date, the equivalent market
value per share of NEC Common Stock would have been $20.37 on such date. On
April __, 1997, the last trading day before the printing of this Joint Proxy
Statement/Prospectus, the last reported per share sales price of Sylvan Common
Stock and NEC Common Stock was $______ and $__________, respectively. Assuming
the Closing Date were _________, 1997, the Average Share Price would have been
$______, triggering either party's Termination Option and Sylvan's Adjustment
Option. Sylvan will not exercise its Adjustment Option if the Average Per Share
Price is lower than $29.13. See "THE MERGER AGREEMENT--Termination." The market
prices of shares of Sylvan Common Stock and NEC Common Stock are subject to
fluctuation. As a result, Sylvan and NEC stockholders are encouraged to obtain
current market quotations.

     Neither Sylvan nor NEC has declared or paid any cash dividends on the
Common Stock.  Sylvan currently intends to retain its earnings for future growth
and, therefore, does not anticipate paying cash dividends in the foreseeable
future.

                                 RISK FACTORS

FLUCTUATION IN VALUE OF MERGER CONSIDERATION

     The number of shares of Sylvan Common Stock to be issued in the Merger is
subject to increase, at the option of Sylvan (subject to NEC's right to
terminate the Merger if Sylvan does not adjust the Initial Conversion Ratio).
Assuming the Merger were scheduled to have occurred on _________, 1997, the date
prior to the printing of this Joint Proxy Statement/Prospectus, the Average
Share Price would have been $_____, triggering NEC's option to terminate the
Merger Agreement unless Sylvan increases the Conversion Ratio from 0.58 to
__________.  If the Conversion Ratio were to be so adjusted, the maximum number
of shares of Sylvan Common Stock issuable to NEC stockholders would be
________________.

     ALTHOUGH THE INITIAL CONVERSION RATIO WILL BE BASED ON THE AVERAGE SHARE
PRICE OF SYLVAN COMMON STOCK, THE MARKET PRICE OF SYLVAN COMMON STOCK MAY
FLUCTUATE AND, ON THE DATE OF THE EFFECTIVE TIME, THE DATE OF RECEIPT OF SHARES
OF SYLVAN COMMON STOCK BY HOLDERS OF NEC COMMON STOCK, OR THE DATE ON WHICH SUCH
SHARES OF SYLVAN COMMON STOCK ARE EVENTUALLY SOLD, MAY BE MORE OR LESS THAN THE
AVERAGE SHARE PRICE OF SYLVAN COMMON STOCK OVER THE PRICING PERIOD.

     In addition, a portion of the shares of Sylvan Common Stock issued in
connection with Sylvan's December 1995 acquisition of Drake Prometric, L.P. will
be freely transferable beginning in April 1997 and additional shares will become
salable at that time, subject to the volume and manner of sale limitations of
Rule 144 of the Securities Act of 1933, as amended. One-year registration rights
relating to all of these shares begins on October 31, 1997. Public availability
of these shares of Sylvan Common Stock may adversely affect the market price of
the Sylvan Common Stock before the Merger, with or without triggering the above-
described rights to terminate the Merger or adjust the Initial Conversion Ratio,
and after the Merger.

UNCERTAINTIES IN INTEGRATING BUSINESS OPERATIONS AND ACHIEVING COST SAVINGS

     In determining that the Merger is in the best interests of its
stockholders, each of the Sylvan Board and the NEC Board considered potential
synergies, efficiencies and cost savings as a result of the combination of
Sylvan's and NEC's operations.  The integration of operations following the
Merger will present significant management challenges.  Specifically, the
integration of operations will require the dedication of management resources
which will temporarily detract from attention to the day-to-day business of the
combined company.  Also, the process of combining the two organizations may
cause an interruption of, or a loss of momentum in, the activities of either or
both of the companies' businesses, which could have a material adverse effect on
the operating results of the combined company.  Thus, there can be no assurance
that the combined company will be able to manage the combined operations
effectively or realize any of the anticipated benefits of the Merger, including
synergies of operations or efficiencies from the elimination of duplicative
functions.  Nor can there can be any assurance as to when, if ever, the
successful integration of operations will be accomplished.

COMPETITION

     There is significant and increasing competition in the remedial,
supplemental and distance learning and professional education marketplaces.  In
addition, an increasing number of private, for-profit organizations; public and
non-public schools; and existing colleges and universities are establishing or
may hereafter establish their own supplemental education programs.  Many of
these organizations have greater financial resources than the combined company.

                                      -26-
<PAGE>
 
FOREIGN EXCHANGE RISK

     A significant portion of the combined company's revenues are generated from
operations outside of the United States, and are billed and collected in
denominations other than the U.S. dollar.  Accordingly, significant fluctuations
in exchange rates between the U.S. dollar and other currencies in which the
combined company does business could have an adverse effect on the combined
company's financial performance.

PROPRIETARY RIGHTS

     The success of Sylvan and NEC and, after the Merger, the combined company,
and their ability to compete are dependent in major part upon their creation of
proprietary products and properties.  Sylvan and NEC rely upon trademark,
service marks, trade secret, patent and copyright laws, in addition to
confidentiality and licensing agreements, to establish and protect their
proprietary rights in intellectual property.  The policy of Sylvan and NEC and,
after the Merger, the combined company, is and will continue to be to seek to
control access to and distribution of proprietary information through
confidentiality agreements with relevant third parties.  Despite these
precautions, it may be possible for a third party to copy or otherwise obtain
and use the proprietary products and documentation without authorization, or to
develop similar products and documentation independently.  In addition,
effective copyright and trade secret protection may be unavailable or limited in
certain venues.  To license its products, Sylvan and NEC and, after the Merger,
the combined company, intend to continue to rely on the license agreements, the
legal efficacy of which may not prove to protect them fully, and which may be
unenforceable under the laws of certain jurisdictions.  Despite efforts to
protect aspects of the products of Sylvan and NEC and, after the Merger, the
combined company, unauthorized parties may attempt to copy aspects of the
products of Sylvan and NEC and, after the Merger, the combined company, or to
obtain and use information that they, or any of the them, regard as proprietary.
Unauthorized use of such products and information is difficult to detect and
police, and there can be no assurance that the steps taken will prevent
misappropriation of products and information of Sylvan and NEC and, after the
Merger, the combined company.  In addition, litigation may be necessary in the
future to enforce the combined company's intellectual property rights, to
protect its trade secrets, to determine the validity and scope of the
proprietary rights of others, or to defend against claims of infringement or
invalidity.  Such litigation could result in substantial costs and diversion of
resources and could have a material adverse effect on the business, operating
results and financial condition of Sylvan or NEC or, after the Merger, the
combined company.  There can be no assurance that any patents, trademarks,
service marks or copyrights issued to Sylvan and NEC or, after the Merger, the
combined company will not be invalidated or circumvented or otherwise be
insufficient to protect their proprietary rights.

     NEC relies and, after the Merger, the combined company will continue to
rely upon certain technology and intellectual property rights that they license
from third parties.  There can be no assurance that these third-party licenses
are or will continue to be available on commercially reasonable terms or at all.
The loss of or inability to obtain or to retain any of these technology or
intellectual property rights could materially adversely affect the business,
operating results and financial condition of Sylvan or NEC or, after the Merger,
the combined company.

DEPENDENCE ON KEY PERSONNEL

     The combined company is dependent in large part on the experience and
knowledge of key personnel including R. Christopher Hoehn-Saric and Douglas L.
Becker (the Co-Chief Executive Officers of Sylvan), Sam Yau (the Chief Executive
Officer of NEC), B. Lee McGee (the Chief Financial Officer of Sylvan) and the
Presidents of the three operating divisions of each of Sylvan and NEC.  The
loss of services of these key individuals could have a material adverse effect
on the combined company.  The success of the combined company is also dependent
upon the continued service of, and its ability to attract and retain highly
qualified technical, marketing, sales and management personnel.  The competition
for such personnel is intense.  The failure to recruit and retain additional or
substitute key personnel in a timely manner could have an adverse effect on the
performance of the combined company.  Sylvan maintains an aggregate of $4.5
million of key man life insurance for each of Messrs. Hoehn-Saric

                                      -27-
<PAGE>
 
and Becker and $3.0 million of key man life insurance for Mr. McGee. NEC
maintains $5.0 million of key man life insurance for Mr. Yau.

RISKS RELATED TO SYLVAN'S OPERATIONS

     Dependence on Profitable Franchise Operations; Dependence on Franchisees
for Technology Centers.  More than 90% of Sylvan Learning Centers are currently
operated by franchisees.  Sylvan's revenues from franchised Learning Centers
depend on the franchisees' ability to operate their Learning Centers profitably
and adhere to Sylvan's standards.  Although Sylvan has a quality review process,
it cannot be certain that franchisees will conduct their operations profitably
or in accordance with Sylvan's guidelines.  The closing of unprofitable Learning
Centers or the failure of franchisees to comply with Sylvan policies could
adversely affect its reputation and business prospects.

     If Sylvan is unable to attract new franchisees meeting its standards or to
convince existing franchisees to open additional Learning Centers, any growth in
royalties from franchised Learning Centers will depend solely upon increases in
revenues at existing Learning Centers.

     Limitations from Franchise Regulation.  Sylvan is subject to federal and
state laws regulating the offer and sale of franchises.  These laws impose
registration and extensive disclosure requirements on the offer and sale of
franchises.  These laws frequently apply substantive standards to the
relationship between franchisor and franchisee and limit the ability of a
franchisor to terminate or refuse to renew a franchise.  State franchise laws
may delay or prevent Sylvan from terminating a franchise or withholding consent
to renewal or transfer of a franchise, and Sylvan may, therefore, be required to
retain a poorly performing franchisee and may be unable to replace the
franchisee, which could have an adverse effect on franchise royalties.  In
addition, the nature and effect of any future legislation or regulation on
Sylvan's franchise operations cannot be predicted.

     Importance of Computer-Based Testing.  A significant amount of the growth
in Sylvan's revenues and profits is projected to result from computer-based
testing services.  The termination, nonrenewal or material modification of
Sylvan's contracts with ETS, Novell or Microsoft or any other significant
agreements to provide computer-based testing services would have a materially
adverse effect on Sylvan's results of operations and prospects for growth.

     Sylvan only began providing computer-based testing services in late 1991,
and there can be no assurance that computer-based testing will receive
sufficient market acceptance to cause test administrators to continue to offer
computer-based tests or convert additional tests to computer-based versions in
the near future.  Furthermore, there can be no assurance that events beyond the
control of both Sylvan and test administrators, such as testing security
concerns, will not reduce or limit market acceptance of computer-based testing
or discourage test administrators from continuing to offer computer-based tests
or converting additional tests to a computer-based format.

     Limited Title I Experience.  A significant amount of Sylvan's growth also
is projected to result from its contract educational services.  Sylvan has
provided educational services funded under federal Title I and similar state
programs only since the spring of 1993, when Sylvan's Title I program was first
offered in public schools in Baltimore, Maryland.  Since 1993, the number of
public schools in Baltimore in which Sylvan's services are offered has increased
significantly.  Sylvan also currently provides Title I services to students
attending non-public schools, pursuant to contracts between local public school
authorities and entities recently acquired by Sylvan.  There can be no assurance
that contracts with existing school districts will be renewed or that Sylvan
will obtain contracts with other school districts.  The majority of Sylvan's
contracts contain provisions for cancellation by school district officials based
on certain factors, including funding constraints.

     Limited Title I Market for Federal-Funded Contract Services; Possible
Opposition to Services; Legislative Reauthorization of Title I.  The market for
Sylvan's Title I services is effectively limited to the nation's larger school

                                      -28-
<PAGE>
 
districts, in which the population of students eligible for Title I services and
per pupil Title I expenditures make Sylvan's services cost-effective.  Many
educators and policy makers have criticized the "pullout" approach, whereby
Title I or similar services are provided in a separate classroom during regular
school hours.  This approach is the method currently prescribed by the Baltimore
City Schools, as well as by other school districts in which Sylvan currently
provides Title I services, and also is the method prescribed by many other
school districts that are potential clients of Sylvan.  School districts to
which Sylvan now provides educational services under contract may decide not to
renew existing contracts, and other school districts may decide not to use
Sylvan's services because government agencies, parents and collective bargaining
units representing teachers and aides may oppose Sylvan's Title I or similar
programs based on the nature of Sylvan's teaching method or the potential threat
to teacher and aide employment.

     Enactment of the Improving America's School Act of 1994 reauthorized the
Chapter I program for an additional five years, effective July 1, 1995, under
the name Title I of the Elementary and Secondary Education Act ("Title I").
Title I includes at least three substantive  changes which potentially could
have a material adverse effect on Sylvan.  First, Title I provides greater
impetus for school districts to implement schoolwide programs aimed at boosting
achievement of disadvantaged children by improving a school's overall program.
Sylvan currently provides "pullout" as opposed to schoolwide services.  Second,
Title I may reduce the reliance of school districts on standardized tests as a
means of measuring student performance, by requiring states to develop and apply
assessments involving multiple measures of student performance.  Sylvan's
services now include the provision of standardized tests to measure student
performance.  Third, Title I may cause reductions in the extent of services
available to disadvantaged students attending non-public schools, rather than
(as under Chapter I) reduction in the number of disadvantaged students attending
non-public schools who are entitled to receive services.  Sylvan cannot
accurately predict the likely impact these substantive changes will have on
Sylvan's contracts to provide Title I services or Sylvan's ability to have those
contracts renewed or its ability to enter into contracts with additional school
districts.

RISKS RELATED TO NEC'S OPERATIONS

     Product Development and Distribution; Dependence on New, Updated and
Licensed Products.  Revenue growth for NEC is dependent upon the successful
development and distribution of a substantial number of new courses and products
each year, as well as the successful revision and updating of existing products.
While NEC has entered into certain arrangements to provide for the timely
development of new products and for the licensing of courses and products from
third parties and NEC makes substantial investments in product development and
product acquisition, and is constantly looking for new product opportunities,
there is no assurance that it will be successful in these efforts in the future.
Failure to timely obtain or develop competitive new products, the loss of access
to third party courses and products, and the loss of relationships with
distributors likely would have a material adverse effect on NEC's financial
performance and prospects for growth.

     Shifts in the Marketplace and Technology.  The market for media-based
training products is growing.  However, no assurance can be given this market
will continue to grow.  A reversal in this trend toward media-based training
products with a shift toward instructor-led training or otherwise could have an
adverse effect on NEC's financial performance.  In addition, many of NEC's
products are technology-based and are delivered to the learner in a computer-
based format using currently available technology, such as CD-ROM.  Although NEC
believes that it is well positioned to incorporate advances in technology into
its products and the delivery of its products, there can be no assurance that
changes in technology, such as rapid development of internet, satellite or other
electronically deployable products, will not cause NEC's products or the methods
of delivery of its products to become obsolete, and thereby require a
significant investment to keep NEC's products and methods of delivery current.
Failure to timely and effectively respond to such technology changes could have
an adverse effect on NEC's operating results.

     Volatility of Media Costs.  The ability of ICS Learning Systems, Inc.
("ICS") to attract new students is dependent, in large part, on the success of
its advertising efforts.  The cost of television time, in particular, which
represents approximately 30% of ICS's annual advertising expenditures, is more
volatile than the advertising cost of

                                      -29-
<PAGE>
 
other media. To date, ICS has been able to purchase favorably priced
"preemptive" television time, "remnant" print space, and other advertising at
attractively negotiated rates. From time to time, ICS has faced increased
competition for such advertising outlets. Higher costs and reduced advertising
availability resulting from such competition, as well as general rate increases,
would raise the cost of attracting new students and could have an adverse effect
on ICS's operating results.

     Regulation of Home Study Schools.  ICS is subject to the regulations of the
Federal Trade Commission, certain licensing standards, including the regulations
of the State of Pennsylvania State Board of Private Licensed Schools, the
accreditation standards of the Distance Education Training Council and various
foreign, federal and state laws and regulations, including the Council for the
Accreditation of Correspondence Colleges of the United Kingdom.  Failure to
maintain these required licenses and accreditations would have a material
adverse effect on ICS's business.  To date, ICS has been successful in
addressing inquiries; however, an adverse action by an entity with regulatory,
licensing or accreditation authority would have a material adverse effect on
ICS's business.  To the extent that other states are successful in subjecting
ICS to their regulatory framework, such regulation could significantly increase
the administration and operating costs of ICS.  ICS cannot predict the nature or
effect of future legislation or regulation on its business operations or
financial condition.

     Conversion of Sales Leads and Course Completion.  ICS's sales and
profitability depend, in significant part, on its ability to convert sales leads
(i.e., inquiries prompted by its advertising and promotional materials) into
enrollments and to motivate its students to progress in and complete courses.
While ICS believes it has developed a cost- effective direct marketing system
and that its course materials and multiple media instruction, testing and
delivery methods are designed to encourage its students to maintain a continued
relationship with ICS through course progression and completion, there can be no
assurance that ICS will be able to maintain or improve its conversion and/or its
course completion rates.  A decline in conversion or completion rates would have
an adverse effect on ICS's financial performance.

     Sales and Use Taxes; Interstate Commerce.  Various states are seeking to
impose sales or use taxes on interstate activities of direct response marketers.
Legal issues relate, among other things, to the required nexus of a business
with a particular state, which may permit the state to require a business to
collect such taxes.  ICS's correspondence school business does not maintain any
domestic offices or sales representatives for its programs outside the
Commonwealth of Pennsylvania and does not collect sales tax on its tuition
payments from its students outside of Pennsylvania.  The imposition of sales tax
on program tuition would have a negative effect on enrollment levels and would
increase administrative expenses.  There can be no assurance that in the future,
ICS will not be required to collect such taxes.

     Product Development; Dependence on New and Updated Products.  ICS's revenue
growth is dependent in significant part on ICS's expansion into new market
niches, particularly technology and professional market segments.  Successful
expansion into new market segments, such as the technology and professional
market segments, is dependent upon ICS's successful development of a number of
new courses and products each year and the successful revision and updating of
existing products.  There can be no assurance that new courses will be timely
developed or that existing courses will be timely revised or updated.  Also,
there can be no assurance that new and revised or updated courses will compete
effectively with products offered by ICS's competitors.  Failure to timely
develop new products or revise or update existing products will have a material
adverse effect on ICS's financial performance.

     Government Budgets.  Most funding of educational materials is dependent on
government support from one or more sources.  The purchase of educational
materials in the elementary, high school and library markets is generally funded
via state and local taxation revenues.  Many special education and adult
education programs are dependent to a significant extent on federal funding.
Budget deficits affecting federal, state and local governments may limit the
availability of funding for educational programs and libraries.  Future
constraints on educational funding could have an adverse effect on the business
of Steck-Vaughn Publishing Corporation ("SVPC").

                                      -30-

     Decentralization of Purchasing Decisions.  Previously, most decisions for
the purchase of educational materials were made at the school district level.
In recent years, the purchasing decision for many types of educational
materials, particularly supplemental educational materials, has been
increasingly delegated to the school level and the individual teacher level.
Although SVPC believes it is well positioned to compete effectively in the
decentralized environment, failure to effectively identify and reach the
purchasing decision makers could adversely affect SVPC's business.
Additionally, in large part because of the decentralization of educational
product purchasing decision, there is an increasing need to develop new or
alternate channels of distribution to reach effectively the ultimate purchasing
decision makers.  Failure by SVPC to develop such new or alternate channels of
distribution would likely adversely affect its financial performance.

     Seasonality of Revenues.  A disproportionate amount of SVPC's revenues are
generated in the third quarter because most of SVPC's customers purchase
educational materials in the summer months in anticipation of classes commencing
in the fall; and a disproportionate amount of the revenues of National Education
Training Group, Inc. ("NETG") are generated in the fourth quarter principally
because of renewal of annual contracts concentrated during that period.  Failure
of SVPC and NETG to achieve anticipated third and fourth quarter revenues in a
particular year, respectively, would likely adversely affect the operating
results of NEC for that year.

NO DIVIDENDS

     Sylvan has never declared or paid cash dividends.  Sylvan currently expects
to retain its earnings for its business and does not anticipate paying dividends
at any time in the foreseeable future.  The decision whether to apply legally
available funds to the payment of dividends on Sylvan Common Stock will be made
by the Sylvan Board of Directors from time to time in the exercise of its
business judgment.  See "COMPARATIVE STOCK PRICES."

POTENTIAL EFFECTS OF CERTAIN SYLVAN ANTI-TAKEOVER PROVISIONS

     Certain provisions of the Sylvan Charter and By-Laws may have the effect of
making more difficult an acquisition of Sylvan in a transaction that is not
approved by the Sylvan Board of Directors.  For example, the Sylvan Board of
Directors is given the power to issue up to 10,000,000 shares of Preferred Stock
of Sylvan in one or more series, and to fix the rights and preferences as to any
such series, without further authorization of the holders of Sylvan Common
Stock.  In addition, unless the Directors Amendment is approved, the Sylvan
Board of Directors will continue to be divided into three classes, each of which
serves for a staggered three-year term, making it more difficult for a third
party to gain control of the Sylvan Board of Directors.  Also, in September
1996, the Sylvan Board of Directors adopted a shareholders rights plan.  These
Charter and By-Laws provisions and adoption of a "poison pill" generally are
designed to permit Sylvan to develop its businesses and foster its long-term
growth without the disruption caused by the threat of a takeover not deemed by
the Sylvan Board of Directors to be in the best interests of Sylvan and its
stockholders.  They may also have the effect of discouraging a third party from
making a tender offer or otherwise attempting to obtain control of Sylvan even
though such an attempt might be economically beneficial to Sylvan and its
stockholders.  See "PROPOSAL I:  THE SHARE ISSUANCE AND THE MERGER--Comparative
Rights of Stockholders of Sylvan and NEC," and "--Description of Sylvan Capital
Stock--Preferred Stock."

CERTAIN LITIGATION

     On March 13, 1997, a purported class action complaint was filed in Orange
Country Superior Court in Santa Ana, California, seeking to enjoin the Merger
and alleging breach of fiduciary duty by NEC's directors in connection with
their approval of the Merger Agreement and the Merger.  There can be no
assurance that such plaintiffs will not be successful, and neither NEC nor
Sylvan can estimate, based on facts available as of the date of this Joint Proxy
Statement/Prospectus, the possible adverse effects if such plaintiffs are
successful, which could include the inability to consummate the Merger,
rescission of the Merger and monetary damages.

CONFLICTS OF INTEREST

     Certain members of the NEC management and NEC Board of Directors have
interests in the Merger that are in addition to and potentially in conflict with
the interests of the NEC stockholders generally.  The NEC Board of Directors was
aware of these interests and considered them, among other things, in approving
the Merger Agreement and the Merger.  See "PROPOSAL I:  THE SHARE ISSUANCE AND
THE MERGER--Interests of Certain Persons in the Merger."

               INFORMATION CONCERNING THE SYLVAN ANNUAL MEETING

PURPOSE, TIME AND PLACE

     This Joint Proxy Statement/Prospectus is being furnished to stockholders of
Sylvan in connection with the solicitation of proxies by the Sylvan Board from
holders of Sylvan Common Stock for use at the Annual Meeting to be held on June
26, 1997 at 10:00 a.m., local time, at 1000 Lancaster Street, Baltimore,
Maryland 21202 or at any adjournments or postponements thereof.  At the Sylvan
Annual Meeting, holders of Sylvan Common Stock will be asked to consider and
vote upon proposals to approve the: (i) Share Issuance pursuant to the Merger
Agreement;  (ii) Directors Amendment; (iii) Common Shares Amendment; (iv)
Preferred Shares Amendment; (v) 1993 Plan Amendment; (vi) Management Plan
Amendment; (vii) election of the Merger Nominees; (viii) election of the
Contingent Nominees; (ix) Auditor Confirmation; and (x) such other matters as
may properly come before the Sylvan stockholders at the Sylvan Annual Meeting.
Approval of the Share Issuance by Sylvan stockholders is a condition to
consummation of the Merger.  See "PROPOSAL I:  THE SHARE ISSUANCE AND THE
MERGER--The Merger Agreement--Conditions Precedent to the Merger."  Only holders
of record of Sylvan Common Stock at the close of business on the Sylvan Record
Date are entitled to notice of, and to vote at, the Sylvan Annual Meeting.  At
the close of business on the Sylvan Record Date, ____________ shares of Sylvan
Common Stock were outstanding, which constituted the only outstanding voting
securities of Sylvan.

RECORD DATE; QUORUM; REQUIRED VOTE

     The Sylvan Record Date has been fixed at the close of business on May 9,
1997.  Only holders of record of Sylvan Common Stock at the close of business on
the Sylvan Record Date will be entitled to notice of, and to vote at, the Sylvan
Annual Meeting or any adjournment or postponement thereof.  At the close of
business on the Sylvan Record Date, ______________ shares of Sylvan Common Stock
were issued and outstanding and were held by approximately _________ holders of
record.  The Sylvan Common Stock constitutes the only outstanding class of
voting securities of Sylvan, and each share of Sylvan Common Stock is entitled
to one vote on each matter to be acted upon or which may come before the Sylvan
Annual Meeting.  Votes may be cast at the Sylvan Annual Meeting in person or by
proxy.  See "--Proxies."

     The presence at the Sylvan Annual Meeting, either in person or by proxy, of
stockholders entitled to a majority of all votes entitled to be cast will
constitute a quorum to transact business at the Sylvan Annual Meeting.  If a
quorum is not present at the Sylvan Annual Meeting, the stockholders who are
present and entitled to vote at the Sylvan Annual Meeting may adjourn the Sylvan
Annual Meeting from time to time to a date nor more than 120 days after the
original record date without notice other than announcement at the Sylvan Annual
Meeting until a quorum is present.

     The affirmative vote of the holders of a majority of the shares of Sylvan
Common Stock voting on each of the Share Issuance and the Plan Amendments (where
the total number of votes cast on the respective proposal represents over 50% of
all shares of Sylvan Common Stock outstanding on the Sylvan Record Date and
entitled to vote) is required to approve these Sylvan Proposals.  Abstentions
will have the same effect as votes cast against the Share Issuance or either of
the Plan Amendments, as the case may be.  However, broker non-votes (i.e.,
shares held by brokers in street name that are not entitled to vote at the
Sylvan Annual Meeting due to the absence of specific instructions from the
beneficial owners of such shares) will be disregarded and will have no effect on
the votes on the Share Issuance or either of the Plan Amendments.

     The affirmative vote of the holders of at least a majority of the total
outstanding shares of Sylvan Common Stock on the Sylvan Record Date is required
to approve each of the Charter Amendments.  Under the MGCL, in determining
whether the proposal to approve each of the Charter Amendments has received the
requisite number of affirmative votes, abstentions and broker non-votes will be
counted and will have the same effect as a vote against such proposal.

                                      -33-
<PAGE>
 
     A plurality of votes cast in the election for the Sylvan Board Nominees is
necessary for their election.  Broker non-votes will not be counted as shares
present and voting at the Sylvan Annual Meeting for purposes of determining
whether the Sylvan Board Nominees received a plurality.

     As of the close of business on the Sylvan Record Date, Sylvan directors and
executive officers and their affiliates may be deemed to be the beneficial
owners of ____ outstanding shares (excluding shares underlying stock options) of
Sylvan Common Stock, or approximately __% of the then outstanding shares of
Sylvan Common Stock.  It is expected that such executive officers and directors
of Sylvan will vote for approval of each of the Sylvan Proposals.  See
"PROPOSALS VII AND VIII:  ELECTIONS OF SYLVAN BOARD NOMINEES--STOCK OWNERSHIP OF
CERTAIN BENEFICIAL OWNERS, DIRECTORS AND MANAGEMENT--Sylvan."

   THE SYLVAN BOARD UNANIMOUSLY RECOMMENDS THAT SYLVAN STOCKHOLDERS VOTE FOR
                   APPROVAL OF EACH OF THE SYLVAN PROPOSALS.

PROXIES

     Shares of Sylvan Common Stock represented by properly executed proxies
received in time for the Sylvan Annual Meeting will be voted at the Sylvan
Annual Meeting in the manner specified on such proxies.  Proxies which are
properly executed but which do not contain voting instructions will be voted FOR
approval for each of the Sylvan Proposals.  It is not expected that any matter
other than those contemplated by the Sylvan Proposals will be brought before the
Sylvan Annual Meeting; however, if other matters are properly presented, the
persons named in such proxy will have authority to vote in accordance with their
judgment on any other such matter, including without limitation, any proposal to
adjourn or postpone the meeting or otherwise concerning the conduct of the
meeting.  If a proxy is returned which specifies a vote against the Share
Issuance, such discretionary authority will not be used to adjourn the Sylvan
Annual Meeting in order to solicit additional votes in favor of the Share
Issuance.

     The grant of a proxy on the enclosed Sylvan proxy card does not preclude a
stockholder from voting in person at the Sylvan Annual Meeting.  A stockholder
may revoke a proxy at any time prior to its exercise by (i) delivering, prior to
the Sylvan Annual Meeting, to Douglas L. Becker, Secretary, Sylvan Learning
Systems, Inc., 1000 Lancaster Street, Baltimore, Maryland 21202, a written
notice of revocation bearing a later date or time than the proxy; (ii)
delivering to the Secretary of Sylvan a duly executed proxy bearing a later date
or time than the revoked proxy; or (iii) attending the Sylvan Annual Meeting and
voting in person.  Attendance at the Sylvan Annual Meeting will not by itself
constitute revocation of a proxy.

     Sylvan will bear the cost of solicitation of proxies from its stockholders,
except that Sylvan and NEC intend to share equally the cost of preparing and
printing this Joint Proxy Statement/Prospectus relating to the Share Issuance
and the Merger, including related filing fees.  In addition to solicitation by
mail, the directors, officers and employees of Sylvan and its subsidiaries may
solicit proxies from stockholders of Sylvan by telephone, telegram or in person.
Arrangements will also be made with brokerage houses and other custodians,
nominees and fiduciaries for the forwarding of solicitation material to the
beneficial owners of stock held of record by such persons, and Sylvan will
reimburse such custodians, nominees and fiduciaries for their reasonable out-of-
pocket expenses in connection therewith.

     In addition, Sylvan has retained D.F. King & Company, Inc. ("D.F. King") to
assist Sylvan in the solicitation of proxies from stockholders in connection
with the Sylvan Annual Meeting.  D.F. King will receive a fee of $________
as compensation for its services and reimbursement of its out-of-pocket expenses
in connection therewith.  Sylvan has agreed to indemnify D.F. King against
certain liabilities arising out of or in connection with its engagement.

     Representatives of Ernst & Young LLP are expected to be present at the
Sylvan Annual Meeting, where they will have the opportunity to make a statement
if they desire to do so and will be available to respond to appropriate
questions.

                PROPOSAL I:  THE SHARE ISSUANCE AND THE MERGER

     The discussion in this Joint Proxy Statement/Prospectus of the Merger and
the description of the principal terms of the Merger Agreement are subject to
and qualified in their entirety by reference to the Merger Agreement, a copy of
which is attached to this Joint Proxy Statement/Prospectus as Annex I and is
incorporated herein by reference.

BACKGROUND OF THE MERGER

     During the past two years, NEC, with the assistance of BZW, has engaged in
a continued review of various strategic alternatives in each of its three major
business segments.  The review centered on growth opportunities, potential joint
venture partners, acquisitions and start-up opportunities.  From time to time
during this period, representatives of various companies approached NEC on an
informal basis to express interest in exploring various strategic alternatives
with NEC or one of the various operating subsidiaries of NEC.

     Beginning in January 1996, Mr. Sam Yau, President and Chief Executive
Officer of NEC, had several discussions with Douglas L. Becker, President and
Co-Chief Executive Officer of Sylvan, regarding various strategic alternatives
between ICS Learning Systems, Inc. ("ICS") and Sylvan, at which time Sylvan
executed a confidentiality agreement with NEC.  On January 30, 1996, BZW
delivered a private placement memorandum to Sylvan in response to Sylvan's
interest in a possible investment in NEC.  After reviewing this private
placement memorandum, Sylvan concluded its interest was mainly in ICS. On
February 8, 1996, a meeting attended by BZW, Messrs. Yau and Keisling of NEC,
and Messrs. Hoehn-Saric and Becker of Sylvan was held in Dallas, Texas regarding
a possible investment by Sylvan in ICS. On February 16, 1996, Sylvan sent an
initial proposal letter to NEC regarding an investment by Sylvan in ICS. During
the next several months, Messrs. Becker and Yau exchanged correspondence and met
informally in New York on May 15, 1996 to continue those discussions. On July
25, 1996, a meeting was held in Dallas, Texas between Messrs. Yau and Becker,
Sylvan's Co-Chief Executive Officer where possible strategic alternatives
between Sylvan and ICS and Sylvan and NETG were explored in general terms. On
that date, the companies executed confidentiality agreements. However, neither
party found the strategic alternatives suggested by the other to have enough
merit to pursue negotiations on a more formal basis after September 1996. Based
on those discussions, neither party took any further actions relating to an
investment by Sylvan in NEC, ICS or NETG. On October 2, 1996, Mr. Yau wrote to
Mr. Becker formally terminating discussions between NEC and Sylvan relating to a
possible investment by Sylvan in ICS.

     To further evaluate the alternatives available to NEC, the management of
NEC made various contacts with third parties to test the level of market
interest in a strategic transaction involving NEC, as well as an ongoing review
of strategic alternatives.  NEC management and its financial advisors solicited
preliminary indications of interest from several companies for a strategic
alliance with NEC to compare the value indicated by this market test against
NEC's ability to realize value for its stockholders by pursuing other
alternatives.  NEC's financial advisors and management identified companies that
they believed would be possible strategic partners, and prepared an analysis of
NEC and the market for its securities to provide a basis for evaluating any
indications of interest that might be received by NEC.

     Mr. Yau contacted Mr. Becker in early December, suggesting another meeting
to discuss possible synergistic marketing opportunities between Sylvan and ICS
and NETG.  On December 12, 1996, Messrs. Becker and Yau met with the Presidents
of NETG and ICS to discuss these matters.

     On January 3, 1997, Messrs. Yau and Becker discussed for the first time the
possibility of a business combination between Sylvan and NEC, which discussion
was followed by a letter on January 13, 1997 from Mr. Becker to Mr. Yau
formalizing Sylvan's proposal to combine the businesses of NEC and Sylvan.  On
January 23, 1997, the NEC Board of Directors was informed of the results of
several exploratory meetings and discussions regarding the possibility of
certain strategic transactions involving NEC and Sylvan and authorized and

                                      -38-
<PAGE>
 
directed management to continue discussions with Sylvan regarding a business
combination between the two companies.  On January 24, 1997, Mr. Becker met with
Mr. Yau in California.  Mr. Becker indicated at this meeting that Sylvan was
interested in continuing discussions only if Sylvan's stockholders were to
retain majority voting power of any combined entity.

     Sylvan retained Alex. Brown on January 10, 1997 to act as Sylvan's
financial advisor in connection with Sylvan's review and negotiation of possible
business combinations with certain businesses, including the possible merger
with NEC and the rendering of its opinion to Sylvan's Board as to the fairness,
from a financial point of view, to Sylvan in connection with any such
transactions.  During the month of January 1997, Alex. Brown held discussions
with Sylvan senior management and delivered to them various analyses relating to
NEC and a possible business combination with NEC.

     On January 28, 1997, NEC senior management and BZW met by telephone
conference with Sylvan senior management and Alex. Brown to evaluate more
thoroughly a potential acquisition of NEC by Sylvan. During the week following
this conference call, negotiations and preliminary due diligence continued. On
January 31, 1997, NEC executed mutual confidentiality agreements with Sylvan. On
February 3 and 4, 1997, NEC and Sylvan and legal counsel exchanged due diligence
documents. On February 4, 1997, Alex. Brown and BZW met in New York to discuss
the potential merger. On February 6, 1997, Mr. Philip C. Maynard, Vice
President, General Counsel and Secretary of NEC, reviewed due diligence
materials in Baltimore provided by Sylvan and its legal counsel. On the weekend
of February 7, 1997, members of Sylvan and NEC management met in Baltimore to
give divisional management presentations and discussed possible synergies if the
businesses were combined. On February 9, 1997, representatives of Alex. Brown
met with members of Sylvan's senior management to review various analyses of
NEC. On February 10, 1997, those joint management presentations were delivered
at a combined meeting of representatives of the Boards of Directors of both
companies. During the weekend of February 7, 1997, NEC senior management and BZW
and Sylvan senior management and Alex. Brown met in Baltimore to discuss
financial due diligence. Negotiations continued, with Alex. Brown and BZW
meeting in New York to discuss specific terms on February 12, 1997. On February
17, 1997, Alex. Brown, on behalf of Sylvan, submitted a formal proposal to
acquire NEC in a stock-for-stock, tax-free transaction to be accounted for as a
pooling-of-interests. From February 24, 1997 through March 11, 1997, Sylvan and
NEC and their independent auditors conducted vigorous financial and accounting
due diligence in Austin, Baltimore, Irvine, Scranton and Chicago. During this
time, General Counsel and outside legal counsel for each of NEC and Sylvan
conducted in-depth legal due diligence. On February 25, 1997, Sylvan's legal
counsel delivered a draft merger agreement to NEC.

     From February 12 to March 12, 1997, there continued to be extensive arm's-
length negotiations regarding, among other things, the Initial Conversion Ratio,
the circumstances under which a termination fee would be payable and the price
of Sylvan Common Stock at which either party could terminate the Merger
Agreement.

     On February 19, 1997 at a regularly scheduled NEC Board Meeting, the NEC
Board discussed a number of issues, including the potential merger.

     At an NEC Board of Directors meeting held on March 6, 1997, NEC's
management reported on the status of discussions with Sylvan.  At the same NEC
Board meeting, BZW discussed its views on the business and operations of Sylvan,
discussed various analyses relating to the Merger and answered questions
regarding such analyses and prior analyses that had been discussed with the NEC
Board of Directors.  Additionally, on March 6, 1997, representatives of Alex.
Brown made a presentation to senior management and members of the Board of
Directors and discussed with them various analyses relating to the Merger.
Management of each of NEC and Sylvan, along with their respective legal and
financial advisors, continued negotiations until March 11, 1997, including a
meeting on March 9, 1997 in Baltimore, at which time the draft Merger Agreement
was presented to the Boards of Directors of NEC and Sylvan for their respective
reviews.

     On March 11, 1997, each of Sylvan and NEC held a Board of Directors
meeting.  Representatives of Alex. Brown attended by telephone the Sylvan Board
Meeting and orally opined to the Sylvan Board of Directors that, as

                                      -39-
<PAGE>
 
of such date and subject to the review of the definitive agreement, the Initial
Conversation Ratio pursuant to the draft Merger Agreement was fair from a
financial viewpoint to Sylvan. A partner of Piper & Marbury L.L.P. also attended
the meeting by conference call and answered questions of the Board relating to
the terms of the Merger Agreement. At this meeting, the Sylvan Board of
Directors approved the Merger and the draft Merger Agreement, subject to
finalization by Sylvan's senior management and advisors. At the NEC Board of
Directors meeting, NEC's legal advisors reported to the NEC Board of Directors
that NEC and Sylvan had negotiated a nearly final draft of the Merger Agreement
and reviewed its terms with the NEC Board of Directors. The NEC Board of
Directors received the oral opinion of BZW that, as of such date and subject to
review of the definitive Merger Agreement, the Initial Conversion Ratio pursuant
to the draft Merger Agreement was fair, from a financial point of view, to the
holders of shares of NEC Common Stock (other than Sylvan, Merger Sub or any
other wholly-owned subsidiary of Sylvan).  The NEC Board of Directors objected
to the termination fee and certain other provisions of the draft Merger
Agreement.  The NEC Board of Directors agreed to adjourn for several hours to
give its management and advisors an opportunity to renegotiate with Sylvan the
terms in the draft Merger Agreement unacceptable to the NEC Board of Directors.
NEC's legal counsel related to Sylvan's legal counsel the objections of the NEC
Board of Directors to the draft Merger Agreement.  After consultation with its
outside counsel and Alex. Brown, Sylvan agreed to revise certain provisions of
the draft Merger Agreement and very early on the morning of the March 12, 1997
presented a final draft Merger Agreement to NEC.  The NEC Board of Directors
reconvened upon receipt of the revised draft Merger Agreement.  Upon discussion
with its outside legal counsel and BZW about the impact of the revisions, the
NEC Board of Directors approved the Merger and the revised draft Merger
Agreement.  The definitive Merger Agreement was executed and delivered by NEC
and Sylvan at approximately 7:00 a.m., eastern time, on March 12, 1997.  On
March 12, 1997, Alex. Brown and BZW confirmed in writing the oral opinions they
had given on March 11, 1997 to Sylvan and NEC, respectively.

REASONS OF SYLVAN FOR THE MERGER; RECOMMENDATION OF THE SYLVAN BOARD

     THE SYLVAN BOARD OF DIRECTORS HAS UNANIMOUSLY CONCLUDED THAT THE MERGER IS
FAIR TO AND IN THE BEST INTERESTS OF SYLVAN AND ITS STOCKHOLDERS AND RECOMMENDS
THAT SYLVAN'S STOCKHOLDERS VOTE TO APPROVE THE SHARE ISSUANCE.  As discussed
below, Sylvan believes that the strategic fit and strengths of Sylvan and NEC
will enhance Sylvan's competitive position, offer potential cost savings and
opportunities for other synergies, and provide a platform for continued growth,
both internally and through acquisitions.  In reaching its determination, the
Sylvan Board of Directors consulted with management, as well as its advisors,
and considered various factors, including:

     (1) the business, assets, management, competitive position and prospects of
Sylvan and NEC, including the analysis, judgment and advice of Sylvan management
with respect thereto, the synergy opportunities for a combined Sylvan-NEC, the
quality of NEC's assets, the complementary management teams, and the expected
strong competitive position of the combined entity;

     (2) the financial condition, cash flows and results of operations of Sylvan
and NEC, both on a historical and a prospective basis, including the strong
results of operations and cash flows of the combined entity and the accretive
nature of the Merger;

     (3) NEC's strengths in the educational services industry, including but not
limited to its expertise in direct marketing, product development and marketing
of educational products and computer-based training products;

     (4) the significant potential enhancement of the strategic and market
position of the combined entity beyond that achievable by Sylvan alone,
particularly in computer-based training and direct marketing of educational
products and services, both of which offer significant new growth opportunities
for the combined company, and the increase in international business
opportunities expected to result from the combination of the two companies;

                                      -40-
<PAGE>
 
     (5) historical market prices and trading information with respect to Sylvan
Common Stock and NEC Common Stock and the Initial Conversion Ratio to be used as
a basis for converting NEC Common Stock into Sylvan Common Stock;

     (6) the terms and conditions of the Merger Agreement, including the form
and amount of consideration, that the consideration was fair to Sylvan, that
although the Initial Conversion Ratio was subject to increase, Sylvan was
entitled to terminate the Agreement if the Average Share Price is below $29.86,
that the transaction was structured as a stock-for-stock merger and that the
representations and warranties given by NEC were reasonable (See "PROPOSAL I:
THE SHARE ISSUANCE AND THE MERGER The Merger Agreement");

     (7) detailed financial analyses and presentations of Alex. Brown, Sylvan's
financial advisor in connection with the Merger, and its opinion that the
Initial Conversion Ratio in the Merger is fair, from a financial point of view,
to Sylvan (See PROPOSAL I:  THE SHARE ISSUANCE AND THE MERGER Sylvan Financial
Advisor");

     (8) the intended treatment of the Merger as a tax-free reorganization under
the Code and the condition to Sylvan's obligation under the Merger Agreement
that Sylvan receive an opinion from its tax counsel as to the tax-free nature of
the Merger (See "PROPOSAL I:  THE SHARE ISSUANCE AND THE MERGER Certain Federal
Income Tax Consequences" and "PROPOSAL I:  THE SHARE ISSUANCE AND THE MERGER The
Merger Agreement Conditions Precedent to the Merger");

     (9) the intended treatment of the Merger as a pooling-of-interests for
financial reporting and accounting purposes and the condition to Sylvan's
obligation under the Merger Agreement that Sylvan and NEC receive Pooling
Letters from their respective independent auditors.  (See "PROPOSAL I:  THE
SHARE ISSUANCE AND THE MERGER The Merger Agreement Conditions Precedent to the
Merger");

     (10) the increased asset and earnings base and diversification of
businesses of the combined company, which should mitigate the risk of earnings
instability; and

     (11) the opportunity to achieve a larger and more stable platform to
continue to make strategic acquisitions.

     The foregoing discussion of the factors considered by the Sylvan Board of
Directors is not intended to be exhaustive.  In view of the wide variety of
factors considered in connection with its evaluation of the Merger, the Sylvan
Board did not quantify or assign any relative weights to the factors considered
in reaching its determination, although its individual members may have given
different weights to different factors.

     THE SYLVAN BOARD HAS UNANIMOUSLY CONCLUDED THAT THE MERGER IS FAIR TO,
         AND IN THE BEST INTERESTS OF, SYLVAN AND ITS STOCKHOLDERS AND
              UNANIMOUSLY RECOMMENDS THAT SYLVAN STOCKHOLDERS VOTE
                      FOR APPROVAL OF THE SHARE ISSUANCE.

SYLVAN FINANCIAL ADVISOR

     Sylvan retained Alex. Brown on January 10, 1997 to act as Sylvan's
financial advisor in connection with Sylvan's review and negotiation of possible
business combinations with certain businesses, including the possible merger
with NEC and the rendering of its opinion to Sylvan's board as to the fairness,
from a financial point of view, to Sylvan, in connection with any such
transaction.

     At the March 11, 1997 meeting of the Sylvan Board of Directors,
representatives of Alex. Brown made a presentation by telephone with respect to
the Merger and rendered to Sylvan's Board its oral opinion, confirmed in writing
on March 12, 1997 (the "Alex. Brown opinion"), that, as of such date, and
subject to the assumptions made, 

                                      -41-
<PAGE>
 
matters considered and limitations set forth in such opinion and summarized
below, the initial Conversion Ratio was fair, from a financial point of view, to
Sylvan. All information and analyses, other than the Merger Agreement dated as
of March 12, 1997, were as of March 10, 1997. No limitations were imposed by
Sylvan on the scope of Alex. Brown's investigation or the procedures to be
followed by Alex. Brown in rendering its opinion.

     THE FULL TEXT OF THE ALEX. BROWN OPINION IS ATTACHED AS ANNEX II TO THIS
JOINT PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE.
SYLVAN SHAREHOLDERS ARE URGED TO READ THE ALEX. BROWN OPINION IN ITS ENTIRETY
FOR A DISCUSSION OF ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS PLACED
ON THE REVIEW UNDERTAKEN BY ALEX. BROWN IN RENDERING ITS OPINION.  ALEX. BROWN
WAS NOT REQUESTED TO AND DID NOT MAKE ANY RECOMMENDATION TO THE SYLVAN BOARD AS
TO THE FORM OR AMOUNT OF THE CONSIDERATION TO BE PAID BY SYLVAN IN THE MERGER,
WHICH WAS DETERMINED THROUGH ARM'S-LENGTH NEGOTIATIONS BETWEEN THE PARTIES.  IN
ARRIVING AT ITS OPINION, ALEX. BROWN DID NOT ASCRIBE A SPECIFIC RANGE OF VALUE
TO NEC, BUT RATHER MADE ITS DETERMINATION AS TO THE FAIRNESS, FROM THE FINANCIAL
POINT OF VIEW TO SYLVAN, OF THE INITIAL CONVERSION RATIO ON THE BASIS OF THE
FINANCIAL AND COMPARATIVE ANALYSES DESCRIBED BELOW.  THE ALEX. BROWN OPINION IS
FOR THE USE AND BENEFIT OF THE SYLVAN BOARD AND WAS RENDERED TO THE SYLVAN BOARD
IN CONNECTION WITH THE SYLVAN BOARD'S CONSIDERATION OF THE MERGER.  THE ALEX.
BROWN OPINION IS NOT INTENDED TO BE AND DOES NOT CONSTITUTE A RECOMMENDATION TO
ANY STOCKHOLDER OF SYLVAN OR NEC AS TO HOW SUCH STOCKHOLDER SHOULD VOTE WITH
RESPECT TO THE SHARE ISSUANCE OR THE MERGER PROPOSAL.  ALEX. BROWN WAS NOT
REQUESTED TO OPINE AS TO, AND ITS OPINION DOES NOT ADDRESS, SYLVAN'S UNDERLYING
BUSINESS DECISION TO PROCEED WITH OR EFFECT THE MERGER. THE SUMMARY OF THE ALEX.
BROWN OPINION SET FORTH IN THIS JOINT PROXY STATEMENT/PROSPECTUS IS QUALIFIED IN
ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE ALEX. BROWN OPINION.

     It should be understood that, although subsequent developments may affect
the Alex. Brown Opinion, Alex. Brown does not have any obligation to update,
revise, or reaffirm its opinion, and Sylvan's obligation to consummate the
Merger is not conditioned upon an update of the Alex. Brown Opinion.  However,
Sylvan's obligation to consummate the Merger is conditioned upon the Alex. Brown
Opinion not having been withdrawn.

     In connection with its opinion, Alex. Brown reviewed and analyzed: (i) the
Merger Agreement and specific terms of the Merger, (ii) certain publicly
available financial and other information concerning NEC and Sylvan that Alex.
Brown believed to be relevant to its analysis, (iii) certain financial and other
information with respect to the business, operations and prospects of NEC
furnished to Alex. Brown by NEC, including certain presentations made by NEC
management to Sylvan, certain internal analyses prepared by NEC, and projections
of future financial performance of NEC prepared by NEC management, (iv) certain
financial and other information with respect to the business, operations and
prospects of Sylvan furnished to Alex. Brown by Sylvan, including certain
internal analyses prepared by Sylvan and projections of future financial
performance of Sylvan prepared by Sylvan management, (v) the publicly reported
prices and trading activity for the Common Stock of both Sylvan and NEC, (vi) a
comparison of certain publicly-available financial and stock market information
for Sylvan and NEC with similar information for certain other educational
services companies whose securities are publicly traded, (vii) the potential pro
forma impact on Sylvan of the Merger, (viii) a comparison of the financial terms
of the Merger with the publicly-reported financial terms of certain other
business combinations in the educational services industry, and (ix) other
studies, analyses and factors as Alex. Brown deemed appropriate.  In addition,
Alex. Brown had discussions with the management of NEC and Sylvan concerning the
respective businesses, operations, assets, financial conditions and prospects of
their respective companies and the strategic benefits expected to result from a
combination of their businesses and considered such other matters as Alex. Brown
deemed appropriate.  Alex. Brown also considered general economic, market, and
financial conditions as of March 10, 1997.

     In conducting its review and arriving at its opinion, Alex. Brown assumed
and relied upon the accuracy, completeness and fairness of the financial and
other information used by Alex. Brown, including publicly available information,
without assuming any responsibility for the independent verification of such
information and further relied upon the assurances of the management of NEC and
Sylvan that they are not aware of any omitted material facts that would make
such information inaccurate or misleading.

                                      -42-
<PAGE>
 
     With respect to the financial projections of NEC, with the consent of
Sylvan, Alex. Brown assumed that such projections were reasonably prepared on a
basis reflecting the best currently available estimates and judgments of the
management of NEC as to the future financial performance of NEC and that NEC
will perform substantially in accordance with such projections.  With respect to
the financial projections for Sylvan, upon advice of Sylvan, Alex. Brown assumed
that such projections were reasonably prepared on a basis reflecting the best
currently available estimates and judgments of the management of Sylvan as to
the future financial performance of Sylvan and that Sylvan will perform
substantially in accordance with such projections.  The financial projections of
Sylvan and NEC that were provided to Alex. Brown were utilized and relied upon
by Alex. Brown in the Contribution Analysis, Discounted Cash Flow Analysis, and
the Pro Forma Earnings Analysis summarized below.  In performing its analysis,
Alex. Brown made adjustments to certain historical periods for unusual, one-time
and nonrecurring items.

     In arriving at its opinion, Alex. Brown did not conduct a physical
inspection of the properties or facilities of NEC or Sylvan and did not make or
obtain any evaluations or appraisals of the assets or liabilities of NEC or
Sylvan.  Upon the advice of Sylvan and its legal and accounting advisors, Alex.
Brown assumed that the Merger would qualify (i) for pooling-of-interests
accounting treatment and (ii) as a reorganization within the meaning of Section
368(a) of the Internal Revenue Code of 1986, as amended, and therefore as a tax-
free transaction to the stockholders of NEC.  Alex. Brown's opinion necessarily
is based upon market, economic and other conditions as they existed on, and
could be evaluated as of, March 10, 1997.

     In connection with the preparation and delivery of its opinion to the
Sylvan Board, Alex. Brown performed a variety of financial and comparative
analyses as summarized below.  The preparation of a fairness opinion involves
various determinations as to the most appropriate and relevant methods of
financial, and comparative analysis and the application of those methods to the
particular circumstances and, therefore, such an opinion is not readily
susceptible of summary description.  Furthermore, in arriving at its opinion,
Alex. Brown did not attribute any particular weight to any analysis or factor
considered by it, but rather made qualitative judgments as to the significance
and relevance of each analysis and factor.  Accordingly, Alex. Brown believes
that its analyses must be considered as a whole and that considering any portion
of such analyses and factors, without considering all analyses and factors,
could create a misleading or incomplete view of the process underlying its
opinion.  In performing its analyses, Alex. Brown considered general economic,
market and financial conditions and other matters, many of which are beyond the
control of Sylvan and NEC.  Any estimates contained in these analyses are not
necessarily indicative of actual values or predictive of future results or
values, which may be significantly more or less favorable than as set forth
therein.  Accordingly, such analyses and estimates are inherently subject to
substantial uncertainty.  In addition, analyses relating to the value of
businesses do not purport to be appraisals or to reflect the prices at which
businesses actually may be sold.  Furthermore, no opinion is being expressed as
to the prices at which shares of Sylvan or NEC Common Stock may trade at any
future time.

     Historical Financial Position.  In rendering its opinion, Alex. Brown
reviewed and analyzed the historical and current financial condition of Sylvan
and NEC which included (i) an assessment of each of Sylvan's and NEC's recent
financial statements; (ii) an analysis of each of Sylvan's and NEC's revenue,
growth and operating performance trends; and (iii) an assessment of each of
Sylvan's and NEC's margin changes and leverage based on the audited financial
statements for each company for the fiscal years ended December 31, 1994 and
1995, and unaudited financial statements for the 12 months ended December 31,
1996.

     Historical Stock Price Performance.  Alex. Brown reported to the Sylvan
Board that it reviewed and analyzed the daily closing per share market prices
and trading volume, for each of Sylvan's and NEC's Common Stock, from January 1,
1996 through March 7, 1997.  Alex. Brown also reported that it reviewed the
daily closing per share market prices of the Sylvan Common Stock and NEC Common
Stock and compared the movement of such daily closing prices with the movement
of the S&P 500 average over the period from January 1, 1996 through March 7,
1997.  Alex. Brown noted and reported that, on a relative basis, both Sylvan and
NEC outperformed the S&P 500 during that period.  Alex. Brown further noted
that, on a relative basis, and for the period January 1, 1996 to March 7, 1997
taken as a whole, the Common Stock of NEC and Sylvan performed in a comparable
manner.  

                                      -43-
<PAGE>
 
Alex. Brown also reviewed the daily closing per share market prices of Sylvan
Common Stock and NEC Common Stock and compared the movement of such closing
prices with the movement of a composite average of selected educational services
companies (consisting of Apollo Group, Inc., CBT Group plc, DeVry, Inc., ITT
Education Services, Inc., Learning Tree International, Inc., and Nobel Education
Dynamics, Inc. (collectively, the "Selected Companies")) over the period from
January 1, 1996 through March 7, 1997. Alex. Brown noted and reported that, on a
relative basis, and for the period taken as a whole, both Sylvan and NEC
performed in a comparable manner to the composite average of the Selected
Companies.

     Contribution Analysis.  Alex. Brown reported to the Sylvan Board its
analysis of the relative contribution of Sylvan and NEC, as compared to Sylvan's
relative fully-diluted ownership of approximately 52.7% of the fully diluted
equity capital of the combined company, to the estimated pro forma income
statement of the combined company.  This analysis showed that on an estimated
pro forma combined basis (excluding (i) the effect of any synergies that may be
realized as a result of the Merger, and (ii) any non-recurring expenses relating
to the Merger, and after adjusting for the effect of any one-time, unusual and
nonrecurring charges at both companies for the twelve months ended December 31,
1996), based on the twelve-month period ending December 31, 1996, Sylvan and NEC
would account for approximately 35.2% and 64.8%, respectively, of the combined
company's estimated pro forma 1996 revenue, approximately 41.7% and 58.3%,
respectively, of the combined company's estimated pro forma adjusted 1996
operating income, and approximately 48.0% and 52.0%, respectively, of the
combined company's estimated pro forma adjusted 1996 net income, after assuming
(i) full taxation of NEC's results and (ii) the conversion of NEC's outstanding
convertible debentures as of January 1, 1996.

     Based on management estimates for Sylvan and the average estimate of
selected brokers' reports for NEC for the twelve month period ending December
31, 1997, this analysis showed that on an estimated pro forma combined basis
(excluding (i) the effect of any synergies that may be realized as a result of
the Merger, and (ii) any non-recurring expenses relating to the Merger), based
on the twelve-month period ending December 31, 1997, Sylvan and NEC would
account for approximately 39.5% and 60.5%, respectively, of the company's
estimated pro forma 1997 revenue, and approximately 42.2% and 57.8%,
respectively, of the combined company's estimated pro forma 1997 operating
income.

     In its analysis of contributions to estimated pro forma net income for the
twelve month periods ending December 31, 1997 and December 31, 1998, Alex. Brown
calculated the estimated pro forma net income of the combined company in two
manners.  First it calculated the net income of the combined company based on
mean the Institutional Brokers Estimating System ("IBES") estimates for the net
income for Sylvan and NEC.  This analysis showed that on an estimated pro forma
combined basis (excluding (i) the effect of any synergies that may be realized
as a result of the Merger, and (ii) any non-recurring expenses relating to the
Merger), based on the twelve-month periods ending December 31, 1997 and December
31, 1998, Sylvan and NEC would account for approximately 44.6% and 55.4%,
respectively, of the combined company's estimated pro forma 1997 net income, and
approximately 48.3% and 51.7%, respectively, of the company's estimated pro
forma 1998 net income.

     Alex. Brown also calculated the combined company's estimated pro forma net
income for the twelve month periods ending December 31, 1997 and December 31,
1998 based on mean IBES estimates for Sylvan and on management projections for
NEC, adjusted for the effect of the full taxation of NEC's results, and assuming
the conversion of NEC's outstanding convertible debentures on January 1 of each
year.  This analysis showed that on an estimated pro forma combined basis
(excluding (i) the effect of any synergies that may be realized as a result of
the Merger, and (ii) any non-recurring expenses relating to the Merger), based
on the twelve-month periods ending December 31, 1997 and December 31, 1998,
Sylvan and NEC would account for approximately 48.3% and 51.7%, respectively, of
the combined company's pro forma 1997 net income, and approximately 50.1% and
49.9%, respectively, of the company's estimated pro forma 1998 net income.

     Analysis of Certain Other Publicly Traded Companies.  This analysis
examines a company's valuation in the public market as compared to the valuation
in the public market of other selected publicly traded companies.  Alex. Brown
compared certain financial information (based on the commonly used valuation
measurements 

                                      -44-
<PAGE>
 
described below) relating to Sylvan and NEC to certain corresponding information
from the Selected Companies. Such financial information included, among other
things, (i) common equity market valuation; (ii) operating performance; (iii)
ratios of common equity market value as adjusted for debt and cash ("Enterprise
Value") to revenues, earnings before interest expense and income taxes ("EBIT"),
and earnings before interest expense, income taxes and depreciation and
amortization ("EBITDA"), each for the latest reported twelve month period as
derived from publicly available information; and (iv) ratios of common equity
market prices per share ("Equity Value") to historical and estimated earnings
per share ("EPS"). The financial information used in connection with the
multiples provided below with respect to Sylvan, NEC and the Selected Companies
was based on the latest reported twelve month period for each company as derived
from publicly available information and on estimated EPS for calendar years 1997
and 1998 as reported by IBES.

     Alex. Brown noted that, on a trailing twelve month basis, the multiple of
Enterprise Value to revenues was 5.6x for Sylvan and 2.4x for NEC, compared to a
range of 1.2x to 18.5x, with a mean of 3.4x, for the Selected Companies; the
multiple of Enterprise Value to EBIT was 35.9x for Sylvan and 19.7x for NEC,
compared to a range of 11.1x to 93.9x, with a mean of 26.4x, for the Selected
Companies.  The mean multiples of Enterprise Value to revenues and EBIT excluded
the Enterprise Value multiples of CBT Group plc.

     Alex. Brown further noted that the multiple of Equity Value to trailing
twelve month EPS was 52.3x for Sylvan and 26.0x for NEC, compared to a range of
25.6x to 86.7x, with a mean of 42.1x, for the Selected Companies; the multiple
of Equity Value to estimated calendar year 1997 EPS was 38.8x for Sylvan and
20.1x for NEC, compared to a range of 23.0x to 56.1x, with a mean of 39.0x, for
the Selected Companies; and the multiple of Equity Value to estimated calendar
year 1998 EPS was 28.5x for Sylvan and 16.3x for NEC, compared to a range of
17.0x to 38.0x, with a mean of 29.1x, for the Selected Companies.  The mean
multiples of Equity Value to trailing twelve month EPS excluded the Equity Value
multiples of CBT Group plc.

     As a result of the foregoing procedures, Alex. Brown reported to the Sylvan
Board that the multiples for Sylvan and NEC were generally within the range of
the multiples for the Selected Companies.  EPS projections for the Selected
Companies, Sylvan and NEC were based on IBES estimates as of March 10, 1997.
The IBES EPS estimates, as of March 10, 1997, for the calendar year 1997 for
Sylvan was $0.90 and for NEC was $0.80 and for the calendar year 1998 for Sylvan
was $1.23 and for NEC was $0.98.

     Analysis of Selected Mergers and Acquisitions.  Alex. Brown reviewed with
the Sylvan Board the financial terms, to the extent publicly available, of 25
proposed, pending or completed mergers and acquisitions since April 1, 1992 in
the educational services industry (the "Selected Transactions").  Alex. Brown
calculated various financial multiples based on certain publicly available
information for each of the Selected Transactions, and compared them to
corresponding financial multiples for the Merger, based on the Initial
Conversion Ratio of 0.58.  The Selected Transactions reviewed, in reverse
chronological order of public announcement, were: Educateif/NEC (January 1997),
Wall Street Institute/Sylvan (January 1997), Edmark Corporation/IBM (November
1996), True North Corporation/Franklin Quest Co. (August 1996), CRT
Group/Education Technology LLC (August 1996), Becker CPA Review/DeVry, Inc.
(June 1996), Edunetics/NEC (April 1996), Westcott Communications, Inc./K-III
Communications, Inc. (April 1996), J3 Learning Corporation/Gartner Group (April
1996), NTC Publishing Group/Tribune Co. (February 1996), Educational Publishing
Corp./Tribune Co. (January 1996), Dataquest/Gartner Group (December 1995),
Personal Training Systems, Inc./CBT Group plc (November 1995), Drake
Prometric/Sylvan (August 1995), Time Systems Inc./Franklin Quest Co. (March
1995), The PACE Group/Sylvan (February 1995), READS, Inc./Sylvan (February
1995), Whittle Communications/K-III Communications (August 1994), The Wright
Group/Tribune Co. (January 1994), McDougal Littel & Co./Houghton Mifflin Co.
(January 1994), Shipley Associates/Franklin Quest Co. (December 1993), Macmillan
Inc./Paramount Communications (November 1993), TI-IN Network/Westcott
Communications (April 1993), Berlitz International/Fukutake Publishing Co.
(August 1992), and Wicat Systems/Jostens Inc. (April 1992).  Alex. Brown noted
that the multiple of adjusted purchase price (value of consideration paid for
common equity adjusted for debt, preferred stock and cash) to NEC's trailing
twelve month revenues was 2.9x for the Merger versus a range of  0.6x to 5.0x,
with a mean of 2.0x, for the Selected Transactions, and the multiple of adjusted
purchase price to NEC's trailing twelve month 

                                      -45-
<PAGE>
 
adjusted EBIT was 24.2x for the Merger versus a range of 5.9x to 46.0x, with a
mean of 18.1x, for the Selected Transactions. Alex. Brown further noted that the
multiple of the equity purchase price to NEC's adjusted and fully-taxed trailing
twelve month net income (after assuming the conversion of NEC's outstanding
convertible debentures as of January 1, 1996) was 46.2x for the Merger versus a
range of 8.2x to 73.6x, with a mean of 31.2x, for the Selected Transactions. All
multiples for the Selected Transactions were based on public information
available at the time of announcement of such transaction, without taking into
account differing economic, market and other conditions during the five year
period during which the Selected Transactions occurred, or the facts and
circumstances of any of the companies involved.

     Historical Exchange Ratio and Premium Analysis.  Alex. Brown reported to
the Sylvan Board that it reviewed and analyzed the historical ratio of the daily
per share market closing prices of NEC Common Stock divided by the corresponding
prices of the Sylvan Common Stock over the 30, 60 and 90 trading day periods
prior to, and as of March 10, 1997.  Such average exchange ratios for the
aforementioned time periods and as of such date were 0.418, 0.469, 0.483, and
0.459, respectively.  Alex. Brown then calculated the respective premiums over
such average daily exchange ratios represented by the Initial Conversion Ratio
of 0.58, which for the same time periods and as of such date were 38.7%, 23.7%,
20.1%, and 26.4%, respectively.

     Alex. Brown also reviewed the premiums received by target shareholders in
62 selected stock-for-stock transactions accounted for as pooling-of-interests,
with a value of over $250 million, and which occurred in the period January 1,
1996 through March 3, 1997.  The data for this analysis was obtained from
Securities Data Corporation.  Alex. Brown noted that the average premiums
received compared to the reported closing market per share prices for the target
companies four weeks and one day prior to the transaction announcement dates
were 40.0% and 30.9% respectively.  Alex. Brown also noted, that based on the
reported closing market per share prices of Sylvan and NEC stock on March 10,
1997, the price premium represented by the Initial Conversion Ratio was 26.4%.

     Discounted Cash Flow Analysis.  Alex. Brown reported to the Sylvan Board
that it performed a discounted cash flow analysis for NEC.  The discounted cash
flow approach values a business based on the current value of the future cash
flow that the business will generate.  To establish a current value under this
approach, future cash flow must be estimated and an appropriate discount rate
determined.  Alex. Brown used estimates of projected financial performance for
NEC for the years 1997 through 2001 prepared in the following manner:  (i)
projections for the years 1997 and 1998 were provided by NEC management, and
were adjusted to give effect to the full taxation of NEC's results and the
conversion of NEC's outstanding convertible debentures; (ii) projections for the
years 1999 through 2001 were prepared by Alex. Brown in a manner consistent with
the 1997 and 1998 projections, which were then reviewed by and consented to by
the management of Sylvan.  Alex. Brown aggregated the present value of the cash
flows through 2001 with the present value of a range of terminal values.  Alex.
Brown discounted these cash flows at discount rates ranging from 12.0% to 16.0%.
The terminal value was computed based on projected EBITDA in calendar year 2001
and a range of terminal multiples of 15.0x to 17.0x.  Alex. Brown arrived at
such discount rates based on its judgment of the weighted average cost of
capital of publicly traded educational services companies, and arrived at such
terminal values based on its review of the trading characteristics of the Common
Stock of the Selected Companies.  This analysis indicated a range of values of
$22.52 to $30.04 per share, based on NEC's fully diluted shares outstanding.

     Pro Forma Combined Earnings Analysis. Alex. Brown reported to the Sylvan
Board that it analyzed certain estimated pro forma effects of the Merger. Based
on such analysis, Alex. Brown computed the resulting estimated
accretion/dilution to the combined company's EPS estimate for the fiscal year
ending 1997 and 1998, pursuant to the Merger before taking into account any
potential cost savings and other synergies that Sylvan and NEC could achieve if
the Merger were consummated and before any non-recurring costs relating to the
Merger. On this basis, Alex. Brown estimated that on this basis the Merger would
be approximately 10.1% accretive and 8.9% accretive to the combined company's
fully diluted EPS for the fiscal years ending 1997 and 1998, respectively,
calculated based on IBES estimates for net income of Sylvan and IBES estimates
for net income of NEC fully taxed and assuming the conversion of NEC's
outstanding convertible debentures. Alex. Brown also estimated that before 

                                      -46-
<PAGE>
 
taking into account any potential cost savings and other synergies and before
certain non-recurring costs relating to the Merger, the Merger would be
approximately 19.4% and 13.1% accretive to the combined company's fully diluted
estimated pro forma EPS for the fiscal years ending 1997 and 1998, respectively,
calculated based on unadjusted IBES estimates for Sylvan and NEC.

     Relevant Market and Economic Factors.  In rendering its opinion, Alex.
Brown considered, among other factors, the condition of the U.S. stock markets,
particularly in the educational services sector, and the current level of
economic activity.

     No company used in the analysis of other publicly traded companies nor any
transaction used in the analysis of selected mergers and acquisitions summarized
above is identical to Sylvan, NEC or the Merger.  Accordingly, Alex. Brown's
analyses do not take into account differences in the financial and operating
characteristics of the Selected Companies and the companies in the Selected
Transactions and other factors that would affect the public trading value of the
Selected Companies and the Selected Transactions, respectively.

     While the foregoing summary describes the analyses and factors that Alex.
Brown deemed material in its presentation to the Sylvan Board of Directors, it
is not a comprehensive description of all analyses and factors considered by
Alex. Brown.  The preparation of a fairness opinion is a complex process that
involves various determinations as to the most appropriate and relevant methods
of financial analysis and the application of these methods to the particular
circumstances, and, therefore, such an opinion is not readily susceptible to
summary description.  Furthermore, in arriving at its opinion, Alex. Brown did
not attribute any particular weight to any analysis or factor considered by it,
but rather made qualitative judgments as to the significance and relevance of
each analysis and factor.  Accordingly, Alex. Brown believes that its analyses
must be considered as a whole and that selecting portions of its analyses and of
the factors considered by it, without considering all analyses and factors,
would create an incomplete view of the evaluation process underlying the Alex.
Brown Opinion.  In performing its analyses, Alex. Brown considered general
economic, market and financial conditions and other matters, many of which are
beyond the control of Sylvan and NEC.  The analyses performed by Alex. Brown are
not necessarily indicative of actual values or future results, which may be
significantly more or less favorable than those suggested by such analyses.
Accordingly, such analyses and estimates are inherently subject to substantial
uncertainty.   Additionally, analyses relating to the value of a business do not
purport to be appraisals or to reflect the prices at which the business actually
may be sold.  Furthermore, no opinion is being expressed as to the prices at
which shares of Sylvan or NEC Common Stock may trade at any future time.

     Alex. Brown is an internationally recognized investment banking firm and,
as a customary part of its investment banking activities, is regularly engaged
in the evaluation of businesses and their securities in connection with mergers
and acquisitions, negotiated underwritings, competitive bids, secondary
distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes.  The Sylvan Board selected Alex.
Brown based upon its qualifications, reputation, experience and expertise with
respect to merger transactions in general and the valuation of educational
services companies in particular.

     As compensation for its services in connection with the Merger, Sylvan has
paid Alex. Brown a retainer fee of $100,000 (the "Retainer Fee") and has agreed
to pay Alex. Brown a fee of $250,000 upon delivery of its opinion (an "Opinion
Fee"). The fee for Alex. Brown's services is not contingent upon Alex. Brown's
conclusions.  Additionally, Sylvan has agreed to pay Alex. Brown a fee
(including the Retainer Fee and the Opinion Fee), upon consummation of the
Merger, of approximately $3.9 million.  In addition, Sylvan has agreed to
reimburse Alex. Brown for reasonable out-of-pocket expenses incurred in
connection with the Merger, excluding the fees and disbursements of its legal
counsel.  Sylvan has agreed to indemnify Alex. Brown for certain costs,
expenses, losses, claims, damages, and liabilities that may arise out of its
engagement by Sylvan as financial advisor and the rendering of its opinion.

     Alex. Brown is acting as financial advisor to Sylvan in connection with the
Merger.  Alex. Brown has also performed various investment banking services for
Sylvan in the past and has received customary fees for such 

                                      -47-
<PAGE>
 
services. The terms of such fee arrangements with Alex. Brown, which are
customary in transactions of this nature, were negotiated at arm's length
between Sylvan's Board of Directors and Alex. Brown. Alex. Brown has acted as
financial advisor to Sylvan in connection with various capital raising
transactions and other matters, including serving as the lead-managing
underwriter in the December, 1993 initial public offering of the Common Stock of
Sylvan, as the lead managing underwriter in the December, 1995 follow-on
offering of the Common Stock of Sylvan, and as financial advisor to Sylvan in
its December, 1995 acquisition of Drake Prometric, L.P. In the ordinary course
of its business, Alex. Brown may actively trade in the debt and equity
securities of Sylvan and NEC for its own account and for the accounts of its
customers and, accordingly, may at any time hold a long or short position in
such securities. Alex. Brown maintains a market in the Common Stock of Sylvan
and regularly publishes research reports regarding the educational services
industry and the businesses and securities of Sylvan and other publicly traded
companies in the educational services industry.

REASONS OF NEC FOR THE MERGER; RECOMMENDATION OF THE NEC BOARD

     THE NEC BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT, HAS DETERMINED
UNANIMOUSLY THAT THE MERGER AND THE TERMS AND CONDITIONS OF THE MERGER AGREEMENT
ARE ADVISABLE AND FAIR AND IN THE BEST INTERESTS OF NEC AND ITS STOCKHOLDERS AND
RECOMMENDS THAT HOLDERS OF SHARES OF NEC COMMON STOCK VOTE FOR APPROVAL AND
ADOPTION OF THE MERGER AGREEMENT.

     On March 12, 1997, the Board of Directors of NEC unanimously approved the
Merger Agreement and the Merger, determined that the terms of the Merger
Agreement are fair to, and that the Merger is in the best interests of NEC and
its stockholders and, therefore, recommends that the holders of NEC Common Stock
VOTE FOR approval of the Merger Agreement.

     In reaching its determination to approve the Merger, the NEC Board has
identified the following potential benefits of the Merger that it believes will
contribute to the success of the combined company and will benefit NEC
stockholders:

          (1)  the combination of Sylvan and NEC should create a company with
     greater financial strength and stability and with operating units that
     should be able to leverage the strengths of one another to a greater extent
     than would be possible on a standalone or looser strategic alliance basis.
     For example, Sylvan's consumer operations provide an attractive opportunity
     to market content created by NEC's ICS, SVPC and NETG units.  Similarly,
     ICS may provide an outlet for Sylvan to market its supplemental education
     programs though new channels of distribution (e.g., direct response
     marketing) not currently being exploited by Sylvan.

          (2)  the combined company may be able to achieve synergistic benefits
     through the complement of existing and planned products and services.
     Additionally, the Merger may result in significant financial and
     administrative synergies, including elimination of maintaining NEC's status
     as a public reporting company and overhead reductions.

          (3)  the combined company will be a strong market leader in the
     supplemental education business.  As a result, the Sylvan brand name should
     achieve even greater recognition and provide opportunities to leverage that
     name recognition and stature to continue to grow and expand, both through
     internal growth and acquisitions.

          (4)  the management of the combined company will have greater depth
     and expertise. Additionally, the Merger Agreement contemplates that Sam
     Yau, Chief Executive Officer of NEC, and each of the operating heads of
     NEC's business units would remain in place in charge of their respective
     businesses.

                                      -48-
<PAGE>
 
     In reaching its decision to approve the Merger Agreement, and to recommend
that NEC's stockholders vote to approve the Merger and adopt the Merger
Agreement, the NEC Board considered a number of other factors, including, among
other things, the following:

          (1)  the business, operations, properties, assets, financial condition
     and operating results of NEC and NEC's future prospects as an independent
     entity, compared to the effect of a combination with Sylvan, in light of
     the financial condition and prospects of NEC and the current economic and
     business environment, including, but not limited to (i) other possible
     strategic alternatives for NEC, including continuing to execute its stand-
     alone business plan or engaging in various restructuring strategies
     involving the disposition of all or parts of certain of NEC's businesses,
     and (ii) the potential for increased value in the combined Sylvan/NEC
     enterprise, as compared to NEC alone, including synergies and enhanced
     capabilities for entering new educational market niches;

          (2)  reports, analyses and opinions of NEC's management and NEC's
     financial advisor with respect to their due diligence investigations and
     analysis of publicly available information concerning the businesses,
     technology, products, operations, financial condition and prospects of
     Sylvan and that on a combined basis with Sylvan, the companies could create
     new avenues for earnings growth;

          (3)  the presentation by BZW with respect to its financial analysis of
     NEC and Sylvan and the oral opinion of BZW as to the fairness, from a
     financial point of view, of the Initial Conversion Ratio pursuant to the
     Merger Agreement to the holders of shares of NEC Common Stock (see "---
     Opinion of NEC Financial Advisor");

          (4)  the fact that the Initial Conversion Ratio represented a premium
     of approximately 20% to the market value of NEC Common Stock on March 11,
     1997, the last NYSE trading day prior to the decision of the NEC Board to
     authorize execution of the definitive Merger Agreement;

          (5)  recent and current market prices of the Sylvan Common Stock,
     including factors affecting the trading range for Sylvan Common Stock prior
     to the announcement of the transaction and the belief that the Merger
     presented an opportunity for NEC's stockholders to realize future equity
     appreciation based on the NEC Board's perception of the more favorable
     prospects of the combined entity;

          (6)  the fact that the $17.32 value of each share of NEC Common Stock
     would be maintained so long as the average price of Sylvan Common Stock
     during the Pricing Period did not fall below $29.86 per share, that the
     $17.32 value could be increased if the price increase of Sylvan Common
     Stock prior to the Merger exceeded $29.86 per share and that the NEC Board
     reserved the right, but is not obligated, to terminate the Merger Agreement
     if the Average Share Price of Sylvan Common Stock falls below $29.86;

          (7)  the terms and conditions of the Merger Agreement, which were the
     product of extensive arm's-length negotiations, including the circumstances
     of reaching the Initial Conversion Ratio, the conditions to closing and
     rights to termination and certain protections for employees of NEC (see
     "---The Merger Agreement");

          (8)  the compatibility of the respective business philosophies of
     Sylvan and NEC, including the apparent compatibility of senior officers at
     the various operating subsidiaries of Sylvan and NEC;

          (9)  the provisions of the Merger Agreement that permit NEC to
     consider additional bona fide third party offers to acquire NEC and permit
     NEC to provide information to and negotiate with such parties and to
     terminate the Merger Agreement, subject to the payment of significant fees
     and expenses to Sylvan, if prior to the effective time of the Merger the
     NEC Board terminates the Merger Agreement or withdraws or modifies in a
     manner adverse to Sylvan its recommendation pursuant to the NEC Board's
     fiduciary duties (see "---The Merger Agreement---No Solicitation,"
     "---Termination" and "---Termination Fee");

                                      -49-
<PAGE>
 
          (10) the opportunity for NEC stockholders to participate, as holders
     of Sylvan Common Stock, in a larger company of which former NEC
     stockholders would hold approximately 46%, of the outstanding common stock
     of the combined company following the Merger (assuming the Initial
     Conversion Ratio), and to do so by means of a transaction which is designed
     to be tax-free to NEC's stockholders and which would be treated as a
     pooling-of-interests transaction for accounting purposes; and

          (11) the conditions to consummation of the Merger, including the
     requirement that the Merger Agreement is approved by the holders of a
     majority of the outstanding voting power of the NEC Common Stock and that
     the issuance of Sylvan Common Stock in the Merger is conditioned upon the
     requisite vote of the Sylvan stockholders pursuant to the Nasdaq rules or
     applicable law.

     The Board also considered a variety of negative factors in its
deliberations concerning the Merger, including the following factors:

          (1)  the risk that the Average Share Price of Sylvan Common Stock
     prior to the Merger could fall to as low as $29.86, without a right to
     terminate the Merger Agreement and without an adjustment to the Initial
     Conversion Ratio per share, resulting in decreased value of each share of
     NEC Common Stock;

          (2)  the risk that the Average Share Price of Sylvan Common Stock
     during the Pricing Period could fall below $29.86 and either (i) the NEC
     Board may elect not to terminate the Merger Agreement in which case the
     Initial Conversion Ratio will remain in place and the implied value per
     share of NEC Common Stock will be less than $17.32, or (ii) the NEC Board
     may elect to terminate the Merger Agreement in which case either (a) the
     Sylvan Board may allow the Merger Agreement to terminate, or (b) the Sylvan
     Board may increase the Initial Conversion Ratio, provided however, the
     Sylvan Board will not increase the Initial Conversion Ratio beyond .5945
     regardless of the Average Share Price for the Sylvan Common Stock during
     the Pricing Period;

          (3)  the potential impact of the Merger on the interests of NEC's
     customers, suppliers, employees, and the communities in which NEC has
     operated, including the negative impact resulting from cost saving
     initiatives and the impact resulting from being a stockholder in a larger,
     more dynamic combined company;

          (4)  the degree of risk that the synergies and cost savings
     anticipated to be achieved in the Merger would not be achieved, and that
     the operations of the two companies would not be successfully integrated;

          (5)  the risk that key NEC management personnel might not remain with
     NEC after announcement of the Merger;

          (6)  the risk that Sylvan would be unable to maintain its recent level
     of earnings growth;

          (7)  the adverse effects on NEC's business, operations and financial
     condition should it not be possible to consummate the Merger following
     public announcement that the Merger Agreement had been entered into;

          (8)  the interests that the NEC management and the NEC Board of
     Directors may be deemed to have in the Merger that are in addition to their
     interests as stockholders of NEC generally (see "---Interests of Certain
     Persons in the Merger"); and

          (9)  the other risks associated with Sylvan's businesses described
     above under "RISK FACTORS."

     The foregoing discussion of the information and factors considered by the
NEC Board of Directors is not intended to be exhaustive.  In view of the wide
variety of factors considered in connection with its evaluation of the Merger,
the NEC Board of Directors did not quantify or otherwise assign relative weights
to the specific factors considered in reaching its determination, although
individual members of the NEC Board of Directors may have given different
weights to different factors.  In the course of its deliberations, the NEC Board
of Directors did not establish a range of value for NEC; however, based on the
factors outlined above, including the advice of its financial advisor, BZW, the
NEC Board of Directors determined that the Merger is advisable and in the best
interests of NEC and its stockholders.  The NEC Board of Directors voted
unanimously to recommend to the holders of NEC Common Stock that the Merger
Agreement be approved.  For a discussion of the interests of certain members of
NEC's management and the NEC Board of Directors in the Merger, see "---Interests
of Certain Persons in the Merger."

NEC FINANCIAL ADVISOR

     NEC retained BZW to act as its financial advisor in connection with the
Merger and to render an opinion as to the fairness of the Initial Conversion
Ratio to the holders of NEC Common Stock from a financial point of view.  The
full text of BZW's written opinion dated March 12, 1997 (the "BZW Opinion") is
attached to this Joint Proxy Statement/Prospectus as Annex III and is
incorporated herein by reference, and the summary of the opinion set forth below
is qualified in its entirety by reference to the full text of such opinion.
Stockholders of NEC are urged to read such opinion carefully and in its entirety
for a description of the procedures followed, the factors considered, the
assumptions made and the scope of review undertaken, as well as the limitations
on the review undertaken, by BZW in rendering its opinion.

     At the March 11, 1997 meeting of NEC's Board of Directors, BZW delivered
its oral opinion, which subsequently was confirmed by the BZW Opinion, that, as
of such date and based on the matters described therein, the Initial Conversion
Ratio was fair to the holders of NEC Common Stock from a financial point of
view.  BZW did not recommend to NEC's Board of Directors that any specific
exchange ratio should constitute the Initial Conversion Ratio.  No limitations
were imposed by NEC's Board of Directors on BZW with respect to the
investigations made or procedures followed by it in furnishing its opinion.  The
BZW Opinion addresses only the fairness of the Initial Conversion Ratio to the
holders of NEC Common Stock, from a financial point of view, and does not
constitute a recommendation to any such holder of NEC Common Stock as to how
such holder should vote at the Special Meeting.  BZW expressed no opinion as to
the tax consequences of the Merger, and the BZW Opinion does not take into
account the particular tax status or position of any holder of NEC Common Stock.
BZW did not express any opinion as to what the value of the Sylvan Common Stock
actually will be when issued to holders of NEC Common Stock pursuant to the
Merger or the price at which the Sylvan Common Stock will trade subsequent to
the Merger.  In furnishing its opinion, BZW was not engaged as an agent or
fiduciary of NEC's stockholders or any other third party.

     In connection with the preparation of the BZW Opinion, BZW, among other
things: (i) reviewed financial information concerning NEC and Sylvan furnished
to it by both companies, including certain internal financial analyses and
forecasts prepared by the management of NEC and Sylvan; (ii) reviewed publicly
available information concerning NEC, including NEC's Annual Report on Form 10-K
for the year ended December 31, 1995, NEC's Quarterly Reports on Form 10-Q for
the fiscal quarters ended March 31, 1996, June 30, 1996, and September 30, 1996,
respectively, NEC's 1995 Proxy Statement and Annual Report to Stockholders,
various earnings and other public announcements made by NEC and various
published industry and market analyst reports concerning NEC and the NEC Common
Stock; (iii) reviewed publicly available information concerning Sylvan,
including the Sylvan Annual Report on Form 10-K for the year ended December 31,
1995, Sylvan's Quarterly Reports on Form 10-Q for the fiscal quarters ended
March 31, 1996, June 30, 1996, and September 30, 1996, Sylvan's 1995 Proxy
Statement and Annual Report to Stockholders, various earnings and other public
announcements made by Sylvan and various published industry and market analyst
reports concerning Sylvan and the Sylvan Common Stock; (iv) held discussions
with the senior management of NEC and Sylvan concerning the businesses, past and
current business operations, financial condition and future prospects of both
companies, 

                                      -51-
<PAGE>
 
independently and combined; (v) reviewed the stock price and trading history of
the NEC Common Stock and the Sylvan Common Stock; (vi) reviewed the valuation of
selected publicly traded companies which BZW deemed comparable to NEC and
Sylvan; (vii) compared the financial terms of the Merger with selected other
transactions which BZW deemed relevant; (viii) analyzed the pro forma earnings
per share of the combined company; (ix) prepared discounted cash flow analyses
of NEC and Sylvan; (x) reviewed the Merger Agreement; and (xi) made such other
studies and inquiries, and reviewed such other data, as BZW deemed relevant. It
should be noted, however, that BZW did not consider Sylvan's pending acquisition
of Independent Child Study Teams, Inc. and I-R, Inc. in connection with the
preparation of the BZW Opinion.

     As noted above, certain internal management projections were provided by
NEC and Sylvan to BZW for purposes of its analysis in arriving at the BZW
Opinion.  As a matter of course, neither NEC nor Sylvan publishes or makes
generally available internal projections or forecasts as to its future
performance, earnings or financial condition, and such information was not
prepared with a view to public disclosure or in accordance with applicable
accounting guidelines.  These forecasts were based on numerous variables and
assumptions which are inherently uncertain, difficult to predict and may not be
within the control of NEC or Sylvan, including without limitation economic and
competitive conditions.  Consequently, actual results may differ materially from
those set forth in such forecasts.

     The following paragraphs summarize the material quantitative and
qualitative analyses performed by BZW in arriving at the BZW Opinion but do not
purport to be a complete description of the analyses performed by BZW.  BZW
reviewed information that was based on the financial condition of NEC and Sylvan
as of a date or dates shortly before the Merger Agreement was executed as of
March 12, 1997 and based on available stock price information through the close
of trading on the NYSE and the NASDAQ Stock Market, respectively, on March 7,
1997.

     Exchange Ratio Analysis.  BZW reviewed the exchange ratio of each share of
Sylvan Common Stock for each share of NEC Common Stock implied by the daily
closing sale prices of NEC Common Stock and Sylvan Common Stock since March 8,
1995.  BZW noted that the average implied exchange ratio since March 8, 1995 was
0.4875, with a high of 0.8484 on May 17, 1996, a low of 0.2292 on March 9, 1995,
and a current ratio of 0.4270 at March 7, 1997.  BZW also noted that the average
implied exchange ratio since January 3, 1997 was 0.4467.  In addition, BZW
reviewed the premiums represented by the Initial Conversion Ratio compared to
the implied exchange ratios based on the average closing sale prices of the NEC
Common Stock and the Sylvan Common Stock for the trailing one, two, six, twelve
and twenty-four month periods prior to March 7, 1997.  Such premiums (discounts)
were 46%, 32%, 7%, (2%), and 19%, respectively.

     Stock Price and Trading Analysis.  BZW reviewed the trading activity,
including price and volume, of the NEC Common Stock and the Sylvan Common Stock
since March 8, 1995.  With respect to NEC, BZW noted that, since March 8, 1995,
the daily closing sale prices of the NEC Common Stock ranged from a high of
$22.13 on May 17, 1996 to a low of $2.75 on March 9, 1995.  With respect to
Sylvan, BZW noted that, since March 8, 1995, the daily closing sale prices of
the Sylvan Common Stock ranged from a high of $37.13 on February 21, 1997 to a
low of $11.08 on April 20, 1995.  BZW also reviewed the premium represented by
the Initial Conversion Ratio of 0.5800 in the Merger and the implied $20.37 per
share value of NEC based on Sylvan's closing stock price of $35.13 on March 7,
1997, compared to simple average historical closing share prices for the NEC
Common Stock for the trailing one, two, six, twelve and twenty-four month
periods prior to such date.  Such premiums were 43%, 44%, 31%, 31% and 85%.

     Contribution Analysis.  BZW compared the relative contributions of NEC and
Sylvan to the pro forma historical and estimated combined revenue, operating
income, and net income of the combined company for the years ended December
1996, 1997 and 1998.  For such periods, BZW noted that NEC would contribute:
65%, 62% and 58%, respectively, of pro forma combined revenue; 58%, 57% and 54%,
respectively, of pro forma combined operating income; 57%, 65% and 53%,
respectively, of pro forma combined net income, including the utilization 

                                      -52-
<PAGE>
 
of NEC's net operating losses and certain other non-recurring tax benefits and
excluding other nonrecurring items; and 50%, 48% and 48%, respectively, of pro
forma combined net income on a "fully taxed" basis and excluding other
nonrecurring items. BZW noted that, immediately following consummation of the
Merger, stockholders of NEC and Sylvan would own approximately 46% and 54%,
respectively, of the common stock of the pro forma combined company.

     Selected Comparable Company Analysis.  BZW compared certain income
statement parameters of NEC with those pertaining to companies deemed by BZW to
be comparable to NEC for the most recent trailing 12-month period.  BZW also
compared estimated earnings per share for the 12-month period ending December
31, 1997 ("Calendar 1997") .  The companies examined included Apollo Group,
Inc., CBT Group PLC, Computer Learning Centers, Inc., DeVry, Inc., Education
Management Corp., Houghton Mifflin Co., ITT Educational Services, Inc., Learning
Tree International, Inc., Nobel Education Dynamics, Scholastic Corp., Strayer
Education, Inc., Sylvan and Youth Services International, Inc. (collectively,
the "NEC Comparable Companies").  Financial data compared, for the most recent
trailing 12-month period, included equity market capitalization, enterprise
value (i.e., equity market capitalization plus debt plus preferred shares plus
minority interest less cash and cash equivalents), revenues, operating income,
net income, earnings per share, operating margin, and net margin.  Financial
data compared for Calendar 1997 were projected earnings per share as reported by
third party sources.  Multiples compared for the most recent trailing 12-month
period included enterprise value to revenue, enterprise value to operating
income, and price per share to earnings per share.  For calendar 1997, BZW
compared multiples of price per share to projected earnings per share.

     Based on enterprise value to revenue multiples ranging from 5.6x to 0.7x
for the most recent trailing 12-month period obtained for the NEC Comparable
Companies, and after adjusting for NEC's net debt, BZW determined a range of
reference values for the NEC Common Stock of $41.20 to $2.70 with a median of
$15.27.  Based on enterprise value to operating income multiples, for the most
recent trailing 12-month period, ranging from 43.2x to 8.5x for the NEC
Comparable Companies, and after adjusting for NEC's net debt, BZW determined a
range of reference values for the NEC Common Stock of $36.65 to $4.96 with a
median of $16.74.  Based on the NEC Comparable Companies' price per share to
earnings per share multiples ranging from 58.1x to 10.2x for the most recent
trailing 12-month period, and the NEC Comparable Companies' estimated price per
share to earnings per share multiples ranging from 57.1x to 18.3x for estimated
Calendar 1997, BZW determined a range of reference values for the NEC Common
Stock of $24.98 to $4.39 with a median of $17.97, and a range of $33.12 to
$10.61 with a median of $17.57, respectively.  By comparison, based on Sylvan's
$35.13 closing stock price on March 7, 1997, BZW noted that the Initial
Conversion Ratio would represent a value of approximately $20.37 per share of
NEC Common Stock.

     Component Valuation.  BZW derived a reference value range for the NEC
Common Stock based on the three primary components of NEC's operations:
educational publishing, educational services and software training and
development.  BZW's analysis was based on internal estimates of NEC's projected
1997 financial performance by business component.  To value NEC's respective
components, BZW applied a range of share price to Calendar 1997 earnings per
share multiples to the estimated 1997 net income of NEC's respective components.
The estimated calendar 1997 earnings per share amounts for the selected
comparable company multiples utilized in this analysis were as reported by third
party sources.  Selected educational publishing companies deemed comparable by
BZW included Houghton Mifflin Co., John Wiley & Sons, Inc., Plenum Publishing,
and Scholastic Corp. Selected educational services companies deemed comparable
by BZW included Apollo Group, Computer Learning Centers, Inc. DeVry, Inc.,
Educational Management Corp., ITT Educational Services, Inc., Scholastic Corp.,
Strayer Education, Inc., TRO Learning Inc. and Sylvan.  Selected software and
training development companies deemed comparable by BZW included CBT Group plc,
Computer Learning Centers, Inc. Gartner Group, Inc. and Learning Tree
International, Inc.  Based on the analysis described above, BZW determined a
range of reference values for the NEC Common Stock of $26.60 to $13.11 with a
median of $19.61. In addition, BZW conducted a theoretical break-up analysis
based on the component valuation described above, adjusted to include estimated
acquisition premiums and the subsequent estimated tax liabilities that would be
incurred by NEC upon liquidation of NEC on a component basis. Based on this
analysis, BZW determined a range of reference values for the NEC Common Stock

                                      -53-
<PAGE>
 
of $21.38 to $12.90 with a median of $17.00. By comparison, based on Sylvan's
$35.13 closing stock price on March 7, 1997, BZW noted that the Initial
Conversion Ratio would represent a value of approximately $20.37 per share of
NEC Common Stock.

     Selected Comparable Transaction Analysis.  BZW analyzed publicly available
information for selected pending or completed mergers and acquisitions within
the education industry (including educational publishing, educational services,
and software training and development).  In examining these transactions, BZW
analyzed certain financial parameters of the acquired company relative to the
consideration offered.  Financial parameters compared included consideration
offered plus net debt assumed ("total consideration") to the trailing 12-months'
revenue prior to the date of the transaction.  The acquisitions reviewed
included Houghton Mifflin Co./McDougal Littel & Co. (March 1994), Pearson
PLC/Software Toolworks, Inc. (May 1994), Bain Capital, L.P./Jostens Learning
Corp. (June 1995), National Education Corp./Edunetics (December 1995), Softkey
International Inc./Learning Co. (December 1995), Softkey International Inc./MECC
(December 1995), ADP Corp./Sandy Corp. (December 1995), Tribune Co./NTC
Publishing Group (March 1996), Pearson PLC/Harper Collins Education (April
1996), DeVry Inc./Becker CPA Review (June 1996), Thomson Corp./West Publishing
Co. (June 1996), CUC International Inc./Davidson Associates, Inc. (July 1996),
CUC International Inc./Sierra On-Line Inc. (July 1996), Gartner Group/J3
Learning Corp. (August 1996), Educational Technology/CRT Group (August 1996),
IBM Corp./Edmark (December 1996), Sylvan/Wall Street Institute (January 1997)
and Kohlberg Kravis Roberts & Co./KinderCare Learning Centers Inc. (February
1997) (collectively, the "Education Transactions").

     Based on total consideration to the trailing 12-month revenue multiples
obtained with respect to the selected transactions, ranging from 2.1x to 4.1x,
BZW determined a range of reference values for NEC Common Stock of $28.48 to
$13.58, with a median of $20.29.  By comparison, based on Sylvan's $35.13
closing stock price on March 7, 1997, BZW noted that the Initial Conversion
Ratio would represent a value of approximately $20.37 per share of NEC Common
Stock.

     Discounted Cash Flow Analysis.  BZW performed certain discounted cash flow
analyses to estimate the present value of the stand-alone, unlevered (before
interest expense), after-tax cash flows of the financial projections prepared by
the management of NEC.  BZW first discounted the projected, unlevered, after-tax
cash flows from January 1, 1997 through December 31, 2001, using a range of
discount rates from 12.7% to 16.7%.  The range of discount rates was based on
NEC's weighted average cost of capital as estimated  by BZW.  NEC's unlevered
after-tax cash flows were calculated as the after-tax operating earnings of NEC
after adding back non-cash expenses and deducting uses of cash not reflected in
the income statement.  BZW then added to the present value of the cash flows an
assumed terminal value of NEC at December 31, 2001, discounted to present value
using the same range of discount rates.  The terminal value was computed by
multiplying NEC's projected tax effected earnings before interest in the fiscal
year ending December 31, 2001 by terminal multiples ranging from 20.0x to 25.0x.
The range of terminal multiples was selected by BZW based on its judgment and
experience.  Based on this analysis, BZW obtained a range of reference values
for NEC Common Stock, as of December 31, 1996, of $27.95 to $18.83 with a median
of $23.15.  By comparison, based on Sylvan's $35.13 closing stock price on March
7, 1997, BZW noted that the Initial Conversion Ratio would represent a value of
approximately $20.37 per share of NEC Common Stock.

     Pro Forma Earnings Analysis.  BZW analyzed estimated 1997 and 1998 earnings
per share of NEC Common Stock and Sylvan Common Stock, based on financial
projections provided by the respective managements, and estimated the 1997 and
1998 pro forma earnings per share of the combined company based on the Initial
Conversion Ratio and excluding non-recurring items.  This analysis indicated
that, in the absence of synergies and before utilization of NEC's net operating
losses and certain other non-recurring tax benefits, the pro forma earnings per
share of the combined company, as compared to Sylvan as a stand-alone entity,
would increase.

     General.  The preparation of fairness opinions involves various
determinations as to the most appropriate and relevant quantitative and
qualitative methods of financial analysis and the application of those methods
to the particular circumstances; therefore, such opinions are not readily
susceptible to summary description.  In arriving at

                                      -54-
<PAGE>
 
its opinion, BZW did not attribute any particular weight to any analysis or
factor considered by it, but rather made qualitative judgments as to the
significance and relevance of each analysis and factor. Accordingly, BZW
believes that its analyses must be considered as a whole and that considering
any portion of such analyses and current factors could create a misleading or
incomplete view of the process underlying its opinion. In its analyses, BZW made
numerous assumptions with respect to industry performance, general business and
other conditions and matters, many of which are beyond the control of NEC and
Sylvan. Any estimates contained in these analyses are not necessarily indicative
of actual values or predictive of future results or values, which may be
significantly more or less favorable than as set forth therein. In addition,
analyses relating to the value of businesses do not purport to be appraisals or
to reflect the prices at which businesses actually may be sold. Accordingly,
such analyses and estimates are inherently subject to substantial uncertainty.
BZW's opinion and financial analyses were only one of many factors considered by
the NEC Board in its evaluation of the Merger and should not be viewed as
determinative of the views of the NEC Board or management with respect to the
Initial Conversion Ratio or the Merger.

     In arriving at its opinion, BZW did not independently verify any of the
foregoing information and relied on all such information being complete and
accurate in all material respects. Furthermore, BZW did not obtain any
independent appraisal of the properties or assets of NEC or Sylvan. With respect
to the financial and operating forecasts (and the assumptions and bases
therefore), estimates and analyses provided to BZW by NEC and Sylvan, BZW
assumed that such projections, estimates and analyses were reasonably prepared
in good faith and represent the best currently available estimates and judgments
of the respective management of NEC and Sylvan as to the future financial
performance of both companies. BZW noted, among other things, that its opinion
is necessarily based upon market, economic and other conditions existing as of
the date of the opinion and information available to BZW as of the date thereof.

     While BZW selected the NEC Comparable Companies and the Sylvan Comparable
Companies based on the similarities in markets served and businesses conducted,
no company examined in the analysis of selected publicly traded companies is
identical to NEC or Sylvan.  Similarly, no transaction examined in the
Educational Transactions is identical to the Merger.

     BZW was retained based on BZW's experience as a financial advisor in
connection with mergers and acquisitions and in securities valuations generally,
as well as BZW's investment banking relationship and familiarity with NEC.  BZW,
and certain of its affiliates, have provided investment banking and commercial
banking services to NEC from time to time and have received fees for those
services.  Among other things, Barclays Bank PLC, of which BZW is a division, is
the lender under NEC's $50 million revolving credit facility.  In connection
with the Merger, Barclays Bank PLC will be entitled to receive a termination fee
of $250,000 in respect of the early termination of the revolving credit
facility.

     NEC engaged BZW pursuant to a letter agreement dated February 26, 1997 (the
"Advisory Agreement").  The Advisory Agreement provides that, for its services,
BZW is entitled to receive a monthly retainer, reimbursement of its out-of-
pocket expenses and, contingent upon consummation of the Merger, a fee of $4.0
million less the aggregate amount of fees paid to BZW as retainer under the
Advisory Agreement and an engagement letter dated November 21, 1995 regarding
certain investment banking services provided to NEC.  The aggregate amount of
such retainer fees as of March 12, 1997 was $390,000.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The following is a summary of the material Federal income tax consequences
of the Merger. The discussion set forth below is based on currently existing
provisions of the Code, Treasury Regulations thereunder, current administrative
rulings and court decisions. All of the foregoing are subject to change and any
such change could affect the continuing validity of this discussion. The
discussion does not purport to address all of the tax consequences applicable to
a particular stockholder. In particular, the discussion does not address the
special tax rules that may apply to particular categories of stockholders of NEC
Common Stock subject to special treatment

                                      -55-
<PAGE>
 
under the Code, such as foreign holders or holders whose stock was acquired in
connection with stock option plans, stock purchase plans or other compensation
transactions. In addition, the following discussion does not address the tax
consequences of the Merger under foreign, state or local tax laws or the tax
consequences of transactions effected prior to or subsequent to the Merger
(whether or not such transactions are in connection with the Merger). EACH NEC
STOCKHOLDER IS URGED TO CONSULT HIS, HER OR ITS TAX ADVISORS AS TO THE SPECIFIC
TAX CONSEQUENCES OF THE MERGER, INCLUDING THE APPLICABLE FEDERAL, STATE, LOCAL
AND FOREIGN TAX CONSEQUENCES OF THE MERGER IN HIS, HER OR ITS PARTICULAR
CIRCUMSTANCES.

     Sylvan has received an opinion from Ernst & Young LLP, its independent
auditors, and NEC has received an opinion from its outside legal counsel, Irell
& Manella LLP, each dated as of the date of this Joint Proxy
Statement/Prospectus, to the effect that, on the basis of facts, representations
and assumptions set forth in such opinions, for federal income tax purposes: (i)
the Merger will constitute a "reorganization" within the meaning of Section
368(a) of the Code, and Sylvan, Merger Sub and NEC will each be a party to such
reorganization within the meaning of Section 368(b) of the Code; (ii) no gain or
loss will be recognized by Sylvan or NEC as a result of the Merger; (iii) no
gain or loss will be recognized by the stockholders of NEC upon the exchange of
their shares of NEC Common Stock solely for shares of Sylvan Common Stock
pursuant to the Merger, except with respect to cash, if any, received in lieu of
fractional shares of Sylvan Common Stock; (iv) the aggregate tax basis of the
shares of Sylvan Common Stock received solely in exchange for shares of NEC
Common Stock pursuant to the Merger (including fractional shares of Sylvan
Common Stock for which cash is received) will be the same as the aggregate tax
basis of the shares of NEC Common Stock exchanged therefor; (v) the holding
period for shares of Sylvan Common Stock received in exchange for shares of NEC
Common Stock pursuant to the Merger will include the holding period of the
shares of NEC Common Stock exchanged therefor, provided such shares of NEC
Common Stock were held as capital assets by the stockholder at the Effective
Time; and (vi) a stockholder of NEC who receives cash in lieu of a fractional
share of Sylvan Common Stock will recognize a gain or loss equal to the
difference, if any, between such stockholder's tax basis in such fractional
share (as described in clause (iv) above) and the amount of cash received.  It
is a condition to the consummation of the Merger that each opinion of counsel be
confirmed on and as of the Closing Date.

     In rendering and confirming such opinions, Ernst & Young LLP and Irell &
Manella LLP may receive and rely upon representations contained in certificates
(and confirmations thereof) of Sylvan, NEC and others.

ACCOUNTING TREATMENT

     The Merger is intended to qualify as a "pooling-of-interests" transaction
for accounting and financial reporting purposes. The Merger Agreement provides
that it is a condition to each of Sylvan's and NEC's respective obligations to
consummate the Merger that Sylvan and NEC receive Pooling Letters from Ernst &
Young LLP and Price Waterhouse LLP, respectively, at the Effective Time. See 
"--The Merger Agreement--Conditions to the Merger." Under "pooling-of-interests"
accounting, as of the Effective Time, the assets and liabilities of NEC would be
added to those of Sylvan at their recorded book values and the stockholders'
equity accounts of NEC would be combined on Sylvan's consolidated balance sheet.
On a pooling-of-interests accounting basis, income and other financial
statements of Sylvan issued after consummation of the Merger would be restated
retroactively to reflect the consolidated combined financial position and
results of operations of Sylvan and NEC as if the Merger had

                                      -56-
<PAGE>
 
taken place prior to the periods covered by such financial statements. The
unaudited pro forma financial information contained in this Joint Proxy
Statement/Prospectus has been prepared using the pooling-of-interests accounting
method to account for the Merger. See "HISTORICAL AND PRO FORMA SELECTED
FINANCIAL INFORMATION."

APPRAISAL RIGHTS

     Under the MGCL, the holders of Sylvan Common Stock will not have objecting
stockholders' appraisal rights in connection with the Share Issuance, the Merger
Agreement and the consummation of the Merger.  Under the DGCL, the holders of
NEC Common Stock will not have dissenters' appraisal rights in connection with
the Merger Agreement and the consummation of the Merger.  See "Comparative
Rights of Stockholders of Sylvan and NEC--Appraisal Rights."

INTERESTS OF CERTAIN PERSONS IN THE MERGER

     Certain members of NEC management and the NEC Board have certain interests
in the Merger that are in addition to and potentially in conflict with the
interests of stockholders of NEC generally.  The NEC Board of Directors was
fully aware of these interests of management and the NEC Board of Directors and
considered them, among other matters, in approving the Merger Agreement and the
transactions contemplated thereby.

     Merger Nominees.  Pursuant to the Merger Agreement, Sylvan has nominated
each of Sam Yau, Chief Executive Officer and President of NEC, David C. Jones,
Chairman of the Board of NEC, Richard C. Blum, Chairman of Richard C. Blum and
Associates, L.P., a merchant banking firm, and a director of NEC and Michael R.
Klein, a partner at the law firm of Wilmer, Cutler & Pickering and a director of
NEC, for election to the Sylvan Board of Directors effective upon the
consummation of the Merger.  In addition, upon consummation of the Merger, Mr.
Yau will serve as Co-Chief Executive Officer of Sylvan.

     Directors' and Officers' Insurance; Limitation of Liability of NEC
Directors and Officers.  The Merger Agreement requires NEC and Sylvan, after the
Effective Date (the "Indemnifying Parties") to indemnify, defend and hold
harmless, as and to the fullest extent permitted by law, each present and former
director or officer of NEC and its subsidiaries (each an "Indemnified Party")
against any losses, claims, damages, liabilities, costs, expenses (including
reasonable attorneys' fees and expenses in advance of the final disposition of
any claim, suit, proceeding or investigation to each Indemnified Party to the
fullest extent permitted by law upon receipt of an undertaking from such
Indemnified Party to repay such advanced expenses if it is finally and
unappealably determined that such Indemnified Party was not entitled to such
indemnification), judgments, fines and amounts paid in settlement with approval
of the Indemnifying Parties (which approval shall not be unreasonably withheld
of or in connection with any such claim, action, suit, proceeding or
investigation based in whole or in part on or arising in whole or in part out of
(i) his or her actions as such a director or officer or (ii) the Merger
Agreement or the transactions contemplated thereby.  In the event of any such
threatened or actual claim, action, suit, proceeding or investigation (whether
arising before or after the Effective Date), (i) the Indemnifying Parties shall
pay all reasonable fees and expenses of such counsel for the Indemnified Parties
promptly as statements therefore are received, and (ii) the Indemnified Parties
will use all reasonable efforts to assist in the defense of any such matter,
provided that no settlement for which the Indemnified Parties would be liable
will be effected without prior written consent.  The by-laws of NEC also provide
for the indemnification of NEC directors and officers to the fullest extent
permitted by law.

     The Merger Agreement requires that Sylvan shall, to the extent such
insurance is available, cause the persons serving as officers and directors of
NEC immediately prior to the Effective Date to be covered for a period of five
years from the Effective Date by the directors' and officers' liability
insurance policy maintained by NEC (provided that Sylvan and NEC may substitute
therefor policies of at least the same coverage and amounts containing terms and
conditions which are not less advantageous to such directors and officers of NEC
than the terms and conditions of such existing policy); provided, however, that
the surviving corporation will not be

                                      -57-
<PAGE>
 
obligated to make annual premium payments for such insurance to the extent such
annual premiums exceed 125% of the annual premiums payable in 1996 (on an
annualized basis) by NEC for such insurance. The Merger Agreement also provides
that in the event Sylvan is not the surviving corporation of a merger or
consolidation with, or transfers all or substantially all of its assets to,
another entity, Sylvan will make proper provisions so that its successors and
assigns assume the foregoing indemnification and insurance obligations.

     Employment, Non-Competition and Continuity Agreements.  As a condition to
the Merger, Mr. Sam Yau, and the Presidents of ICS, NETG and SVPC must enter
into employment agreements with Sylvan replacing their current agreements with
NEC.  Mr. Yau's replacement employment agreement will provide for employment for
a period commencing at the Effective Time and will include customary non-compete
and non-solicitation provisions extending for a certain period after termination
of his employment with Sylvan.  Mr. Yau's initial annual salary under this
agreement will be $375,000.  Messrs. Keisling and Moran and Ms. Kopec, the
Presidents of the NEC Subsidiaries have agreed to enter into employment
agreements with Sylvan on terms satisfactory to such individuals and to Sylvan,
including customary non-solicitation and non-compete provisions.  In addition,
Sylvan and Messrs. Keith Ogata, NEC's Vice President and Chief Financial
Officer, and Philip C. Maynard, NEC's Vice President and General Counsel both of
whose employment will terminate following a reasonable and mutually agreeable
transition period following consummation of the Merger, have agreed to enter
into continuity agreements with respect to their provision of services during
the transition period and continuation of certain of their benefits after the
Merger.

     Although still under discussion, Mr. Yau will be granted a long-term
incentive compensation package, including stock options, that will be designed
to align Mr. Yau's financial interests with the interests of the Sylvan
stockholders and to provide Mr. Yau an opportunity for value creation based upon
performance similar to the value creation opportunities received by Messrs. Yau,
Becker and Hoehn-Saric in their prior assignments and positions.  Thereafter,
Mr. Yau will be considered for further option awards and participation in other
equity programs when and as other Sylvan executives are considered for and
granted such option awards and other equity participation opportunities.

     NEC Stock Option Plans.  Upon the consummation of the Merger, the NEC Stock
Option Plans and the options granted thereunder shall be deemed to have been
adopted by Sylvan and shall continue as separate plans and options of Sylvan.
Holders of outstanding options to purchase shares of NEC Common Stock ("NEC
Stock Options") shall be entitled to exercise those NEC Stock Options for a
number of shares of Sylvan Common Stock equal to the product of (A) the number
of shares of NEC Common Stock underlying the NEC Stock Option and (B) the
Initial Conversion Ratio or the Adjusted Conversion Ratio, as applicable (the
"Sylvan Option Shares").  The per share exercise price of the Sylvan Options
Shares shall be equal in value to the NEC Stock Option exercise price set forth
in the agreement pursuant to which the NEC Stock Option was granted divided by
the Initial Conversion Ratio or the Adjusted Conversion Ratio, as applicable.
After the Effective Time, no further grants shall be made under the NEC Stock
Option Plans.

     NETG Stock Option Plans.  The NETG Stock Option Plans provide that upon a
change of control, all options granted pursuant to such plans shall immediately
terminate.  However, Sylvan has agreed that, from and after the Effective Time,
then outstanding NETG Stock Options and the related NETG Stock Option Plans
shall continue.

     SVPC Stock Option Plans.  The SVPC stock options and the related SVPC Stock
Option Plans will remain in effect upon consummation of the Merger.

     Options Granted Pursuant to Employment Agreements. Pursuant to the
employment agreement entered into between Mr. Yau and NEC as of March 1, 1995,
Mr. Yau was granted certain options to acquire shares of NEC Common Stock. Mr.
Yau was granted an initial option to purchase 500,000 shares of NEC Common Stock
at the March 17, 1995 closing price (the "Initial Option"). The Initial Option
vests in 36 equal monthly installments commencing on June 1, 1995. In addition,
for a period of 30 days commencing on May 8, 1995, Mr. Yau was

                                      -58-
<PAGE>
 
granted the opportunity to purchase up to 240,000 shares of NEC Common Stock at
the March 17, 1995 closing price with a concomitant grant of options by NEC for
Mr. Yau to purchase two and one-half shares of NEC Common Stock for every share
of NEC Common Stock purchased during the 30 day period (the "Additional
Options"). Pursuant to this agreement, Mr. Yau purchased 240,000 shares of NEC
Common Stock and was granted 600,000 Additional Options, all of which had vested
by the end of the second quarter of 1996.

     Upon the consummation of the Merger, the unvested portion of the Initial
Options will vest.  Accordingly, Mr. Yau will be entitled to exercise
approximately 153,000 Initial Options not otherwise exercisable until July 1,
1997 and monthly thereafter until May 1, 1998,  all such options having an
exercise price of $3.00 per share.  Exercise of these Initial and Additional
Options will be settled by delivery of Sylvan Common Stock in the same manner as
the settlement of NEC Stock Options described above.  As of the Effective Time,
Initial and Additional Options will have an estimated aggregate value of
$15,751,000 (exclusive of the exercise price), assuming the Initial Conversion
Ratio is applicable and assuming the per share value of the Sylvan Common Stock
at the Effective Time is $29.86.

     Officer, Key Employee and Inside Director Stock Options and Restricted
Stock Awards.  Executive and key employees, including employee-directors, of NEC
are eligible to receive stock options and shares of Restricted Stock (the
"Incentive Awards") pursuant to the NEC Amended and Restated 1990 Stock Option
and Incentive Plan (the "Executives Award Plan").  Upon approval of the Merger
by the NEC stockholders, all outstanding Incentive Awards become immediately
vested or otherwise free from restrictions in their entirety.  Accordingly,
immediately after the NEC Stockholders approve the Merger, NEC option plan
participants will be entitled to exercise 965,390 options to purchase shares of
NEC Common Stock, (which will be converted to Sylvan Options as described above)
at a weighted average per share exercise price of $8.47 which would not
otherwise have become exercisable until various times after the Closing.
Specifically, of the 965,390 options that will vest on an accelerated basis,
142,022, 339,755, 192,188, 174,015 and 57,410 would otherwise have become
exercisable during 1997, 1998, 1999, 2000, and 2001, respectively.  These
options will be settled by delivery of Sylvan Common Stock in the same manner as
the settlement of NEC Stock Options as described above.

     Outside Directors' Stock Options.  Options to purchase an aggregate of
142,000 shares of NEC Common Stock, at a weighted average exercise price of
$7.76 per share, have been granted to NEC's non-employee directors pursuant to
the NEC Amended and Restated 1991 Directors' Stock Option and Award Plan (the
"NEC Directors Option Plan").  Upon approval of the Merger by the NEC
stockholders, all outstanding but unvested options granted under the Directors
Option Plan (22,500 options having a weighted average exercise price of $14.16
per share) become immediately exercisable in full.  In the event the Merger is
consummated, these options will be settled by delivery of Sylvan Common Stock in
the same manner as the settlement of NEC Stock Options, as described above.

     Supplemental Executive Retirement Plan.  NEC has in effect an unfunded
Supplemental Executive Retirement Plan ("SERP") which provides for supplemental
retirement income benefits as early as age 60 after completing at least six
years of service for certain of its current and former executive officers
including Messrs. Yau, Ogata, and Maynard.  A participant in the SERP will
receive maximum lifetime retirement income benefits in the amount of 60% of
average earnings (reduced by the amount of a participant's primary social
security benefits) multiplied by the participant's credited service percentage
under the SERP.  The credited service percentage vests at a rate of 10% per year
beginning with the sixth year of credited service and become fully vested after
15 years of credited service.

     In the event of a change of control, the SERP provides that, if a
participant's employment is terminated voluntarily or involuntarily within two
years of such change of control of NEC ("Timely Termination"), the participant
is entitled to receive accelerated vesting and payout of SERP retirement
benefits in a single lump sum. Such lump sum settlement shall be equal to the
actuarial present value of full retirement benefits, assuming that the
participant's employment had continued to age 65, the participant's earnings had
remained unchanged to age 65 and the participant was 65 for purposes of
calculating social security benefits. The participant's earnings are determined
by using the participant's highest annual earnings during the three year period
prior to the change of control. Sylvan

                                      -59-
<PAGE>
 
has agreed that executives will be eligible for benefits under the SERP without
Timely Termination; provided, that (i) SERP participants who remain employees
after the Merger will be entitled to payment of SERP retirement benefits, with
interest from the Effective Date, only upon termination of such participant's
employment and (ii) there will be no further accrual of additional benefits from
and after the Merger. Estimated lump sum payments to which Messrs. Yau, Ogata,
and Maynard are expected to be entitled are approximately: $2,171,000, $805,000
and $586,000, respectively; and all participants as a group (five persons in
total), $5,323,000.

REGULATORY MATTERS

     Under the HSR Act, and the rules that have been promulgated thereunder by
the FTC, the Merger may not be consummated unless certain filings have been
submitted to the Antitrust Division and the FTC and certain waiting period
requirements have been satisfied.  On March 26, 1997, Sylvan and NEC submitted
the to the FTC and the Antitrust Division the filings required to be made in
connection with the Merger. On April 25, 1997, the waiting period under the HSR
Act relating to the Sylvan and NEC filing will expire. Richard C. Blum, a
director and principal stockholder of NEC is deemed under the HSR Act to be
"acquiring" Sylvan by virtue of the expected value of the Sylvan Common Stock as
to which he would acquire beneficial ownership as a result of the Merger and
because he is a Merger Nominee. Accordingly, Mr. Blum was required to make, and
on April __, 1997 made, certain filings with the FTC and Antitrust Division. On

     Under the Merger Agreement, Sylvan and NEC have agreed to use all
reasonable efforts to obtain all necessary material permits, licenses,
franchises and other governmental authorizations necessary or advisable to
complete or effect the Merger.  It is a condition to the parties' respective
obligations to consummate the Merger that all necessary material consents,
approvals, actions of, filings with and notice to any governmental authority or
public or private third parties be obtained.

NASDAQ STOCK MARKET LISTING

     Sylvan has filed an application to list the shares of Sylvan Common Stock
to be issued in connection with the Merger on Nasdaq.

DELISTING AND DEREGISTRATION OF NEC COMMON SHARES

     If the Merger is consummated, the shares of NEC Common Stock will be
delisted from the NYSE and PSE and those shares will be deregistered under the
Exchange Act.

CERTAIN FEDERAL SECURITIES LAWS CONSEQUENCES

     All shares of Sylvan Common Stock issued in connection with the Merger will
have been registered under the Securities Act.  Such shares will be freely
transferable, except that shares received by any person who may be deemed to be
an affiliate within the meaning of Rule 145 of the rules and regulations
promulgated under the Securities Act (each such person being an "Affiliate") of
NEC may not be resold except in transactions permitted by such Rule 145 or as
otherwise permitted under the Securities Act.

     Pursuant to the Merger Agreement, NEC and Sylvan agreed to deliver to each
other a list of those persons who were, in their respective reasonable judgment,
on the date of execution of the Merger Agreement, Affiliates of NEC and Sylvan,
respectively.  NEC and Sylvan have agreed to provide each other with such
information and documents as Sylvan shall reasonably request for purposes of
reviewing such list.  NEC is obligated under the Merger Agreement to use its
best efforts to deliver or cause to be delivered to Sylvan, prior to the
Effective Time, a written agreement substantially in the form agreed to by NEC
and Sylvan, executed by each of the Affiliates of NEC identified in the
foregoing list and by any person who shall have become an Affiliate of NEC
subsequent to the delivery of such list, to the effect that such Affiliate of
NEC will not sell, transfer, exchange, pledge or otherwise

                                      -60-

dispose of, or make any offer or agreement relating to any of the foregoing with
respect to, any shares of Sylvan Common Stock such person acquires in connection
with the Merger except as permitted under Rule 145 of the Securities Act.

THE MERGER AGREEMENT

     The following is a summary of certain material terms of the Merger
Agreement.  The following summary does not purport to be complete and is
qualified in its entirety by reference to the Merger Agreement, which is
attached as Annex I to this Joint Proxy Statement/Prospectus and is incorporated
herein by reference.

     GENERAL

     If the respective approval of (i) Sylvan's stockholders with respect to the
Share Issuance by the requisite vote under applicable law and (ii) NEC's
stockholders with respect to the Merger and the Merger Agreement are obtained,
and all other conditions to the Merger are satisfied or waived, Merger Sub will
be merged with and into NEC, with NEC being the surviving corporation after the
Merger and a wholly-owned subsidiary of Sylvan.  The date on which the closing
of the Merger occurs is referred to herein as the "Closing Date."

     CONVERSION SHARES

     Conversion Ratio.  In the Merger, among other things, each outstanding
share of NEC Common Stock, other than NEC Common Stock held by NEC or held by
Sylvan, Merger Sub or any other wholly-owned subsidiary of Sylvan, will be
converted into the right to receive 0.58 of a share of Sylvan Common Stock (the
"Initial Conversion Ratio"); provided, however, that the Initial Conversion
Ratio may be adjusted upward in the event (i) the average closing price of
Sylvan Common Stock (the "Average Share Price") over a period of ten (10)
trading days preceding the consummation of the Merger (the "Pricing Period") is
less than $29.86 per share (the "Trigger Price"), (ii) the NEC Board has
exercised its option (the "Termination Option") to terminate the Merger
Agreement because the Average Share Price is less than the Trigger Price and
(iii) Sylvan has exercised its option (the "Adjustment Option") to adjust the
Initial Conversion Ratio to equal the quotient of (A) the Trigger Price
multiplied by the Initial Conversion Ratio divided by (B) the Average Share
                                           ------- --                      
Price (the "Adjusted Conversion Ratio").  Assuming the number of shares of
Sylvan Common Stock outstanding on the Closing Date equals the number of shares
of Sylvan Common Stock outstanding on March 17, 1997, Sylvan will not, in any
event, increase the Adjusted Conversion ratio above 0.5945.

     The following table illustrates the effect on the Conversion Ratio using a
range of assumed Average Share Prices:

<TABLE>

</TABLE>

     Fractional Shares.  No certificates for fractional shares of Sylvan Common
Stock will be issued in the Merger, and to the extent that an outstanding share
of NEC Common Stock would otherwise have become a fractional share of Sylvan
Common Stock, the holder thereof, upon presentation of such fractional share
interest represented by an appropriate certificate for NEC Common Stock to the
Exchange Agent as described under "Exchange Procedures" below, will be entitled
to receive a cash payment therefor in an amount equal to the product of (i) the
Average Share Price and (ii) the fractional share interest to which the holder
would otherwise be entitled.

                                      -61-
<PAGE>
 
     NEC Stock Options.  The Merger Agreement provides that following the
Effective Time, each holder of outstanding options to purchase shares of NEC
Common Stock (a "NEC Stock Option") under the NEC option plans, whether vested
or unvested, shall be entitled to exercise such NEC Stock Options at such time
as the holder thereof would otherwise have been entitled to exercise such NEC
Stock Options for a number of shares of Sylvan Common Stock equal to (A) the
number of shares of NEC Common Stock underlying the NEC Stock Options multiplied
by the Conversion Ratio ("Sylvan Option Shares") by payment of consideration
equal in value to the per share NEC Stock Option exercise price set forth in the
agreement pursuant to which the NEC Stock Option was granted divided by the
Conversion Ratio multiplied by the number of Sylvan Option Shares being issued.

     NEC Convertible Debentures.  NEC is a party to an Indenture, dated as of
May 15, 1986, with Continental Illinois National Bank and Trust Company of
Chicago, pursuant to which NEC issued $57.5 million, 6 1/2% Convertible
Subordinated Debentures (the "NEC Convertible Debentures") of which $54.6
million is currently outstanding.  The debentures are convertible to NEC Common
Stock at $25.00 per share.  The Merger Agreement provides that each of NEC and
Sylvan will use their best efforts to cause the Trustee of the Indenture to
amend the Indenture, effective at the Effective Time, so that Sylvan assumes
NEC's rights and obligations thereunder and, so that NEC's obligations in
respect of outstanding NEC Convertible Debentures may be canceled.  In the event
that the Indenture is amended as described, upon the consummation of the Merger,
each holder of the outstanding NEC Convertible Debentures ($_____ principal
amount on the NEC Record Date) will have the right to convert such NEC
Convertible Debentures into a number of shares of Sylvan Common Stock equal to
the product of (A) the number of shares of NEC Common Stock into which the NEC
Convertible Debentures would have been convertible had the Merger not occurred
(which is equal to the value of the NEC Convertible Debentures divided by
$25.00, the per share conversion price) multiplied by (B) the Initial Conversion
                                        ---------- --                          
Ratio or the Adjusted Conversion Ratio, as applicable.

     NEC does not believe that the change in conversion rights on the NEC
Convertible Debentures will constitute an "exchange" within the meaning of the
applicable regulations promulgated under the Internal Revenue Code.  Were the
modification to constitute an exchange, NEC could recognize discharge of
indebtedness income in an amount equal to the excess of the original issue price
of the NEC Convertible Debentures over their fair market value on the date of
consummation of the Merger.  Such discharge of indebtedness income would have no
immediate tax impact, but would reduce NEC's net operating loss carryovers.  NEC
would, however, be entitled to additional interest deductions over the remaining
life of such debentures in an amount equal to any discharge of indebtedness
income.

     Pursuant to a Debenture Purchase Agreement dated February 15, 1991, NEC
issued $20 million senior subordinated convertible debentures, which in
September of 1995 were converted into 5,020,636 shares of NEC Common Stock (the
"Debentures Shares").  Pursuant to its obligations under the Debenture Purchase
Agreement as amended, NEC has filed, and maintained the effectiveness of, a
Registration Statement with the SEC with respect to the Debentures Shares.  No
later than 90 days after the Effective Time, Sylvan has agreed to file a
Registration Statement on Form S-3 relating to the shares of Sylvan Common Stock
which will be issued in respect of shares of NEC Common Stock issued upon
conversion of the Debentures in the fall of 1995, replacing the NEC Form S-3
registration statement on file for such shares.

     Conversion of Merger Sub Common Stock.  Each share of common stock, par
value $.01 per share, of Merger Sub issued and outstanding immediately prior to
the Effective Time will be converted into one share of common stock, without par
value, of NEC as the Surviving Corporation.  Such newly issued shares will
thereupon constitute all of the issued and outstanding capital stock of the
Surviving Corporation.

     EXCHANGE PROCEDURES

     Promptly following the Effective Time, Sylvan will make available to the
Surviving Corporation for deposit with __________________ (the "Exchange
Agent"), for the benefit of and to be distributed to the holders of certificates

                                      -62-
<PAGE>
 
of NEC Common Stock, certificates representing the number of duly authorized
shares of Sylvan Common Stock to be issued in connection with the Merger (and
cash in lieu of fractional shares of Sylvan Common Stock).

     As soon as reasonably practicable after the Effective Time, the Exchange
Agent will mail a form of transmittal letter to the holders of certificates
representing shares of NEC Common Stock.  The form of transmittal letter will
contain instructions with respect to the surrender of such certificates in
exchange for shares of Sylvan Common Stock (and cash in lieu of fractional
shares of Sylvan Common Stock, if applicable).

NEC STOCK CERTIFICATES SHOULD NOT BE RETURNED WITH THE ENCLOSED PROXY CARD AND
SHOULD NOT BE FORWARDED TO THE EXCHANGE AGENT EXCEPT WITH A TRANSMITTAL FORM
WHICH WILL BE PROVIDED TO HOLDERS FOLLOWING THE EFFECTIVE TIME.

     After the Effective Time, there will be no further transfers on the records
of NEC of certificates representing shares of NEC Common Stock, and if such
certificates are presented to the Surviving Corporation for transfer, they shall
be canceled and exchanged for the consideration properly payable pursuant to the
Merger Agreement.  The rights of the NEC stockholders to cause the Surviving
Corporation to exchange their shares of NEC Common Stock for shares of Sylvan
Common Stock (and cash in lieu of fractional shares) expires one year from the
Effective Time.  Thereafter, these NEC stockholders are required to request
exchange from Sylvan.

     No dividends or other distributions declared or made with respect to Sylvan
Common Stock with a record date after the Effective Time will be paid to the
holder of any certificate representing shares of NEC Common Stock until such
certificate has been surrendered for exchange.  Holders of certificates
representing shares of NEC Common Stock will be paid the amount of dividends or
other distributions with a record date after the Effective Time, which dividends
or distributions theretofore had been payable, after surrender of such
certificates, without any interest thereon.

     Neither Sylvan nor the Surviving Corporation will be liable to any former
holder of shares of NEC Common Stock for any number of shares or amount of cash
payable in lieu of fractional share interests delivered to a public official
pursuant to any applicable abandoned property, escheat or similar laws.

     For a description of the differences between the rights of the holders of
Sylvan Common Stock and NEC Common Stock, see "COMPARATIVE RIGHTS OF
STOCKHOLDERS OF SYLVAN AND NEC."

     EFFECTIVE TIME

     On the Closing Date, the parties shall file a Certificate of Merger with
the Secretary of State of the State of Delaware, and the Merger will become
effective at the time of such filing (the "Effective Time").

     REPRESENTATIONS AND WARRANTIES

     The Merger Agreement contains various customary representations and
warranties of the parties, none of which will survive the consummation of the
Merger, made as of the date of the Merger Agreement and to be made as of the
Effective Time, including, among other things, representations from all parties

writing or otherwise to take, any of the actions described above or any action

Merger Agreement untrue or incorrect as of the date when made.

     DIRECTORS' AND OFFICERS' INDEMNIFICATION AND INSURANCE

     The Merger Agreement provides that NEC, and from and after the Effective
Time, Sylvan will maintain all rights of indemnification existing in favor of
directors, officers and employees of NEC or any of its subsidiaries or any
person who becomes an officer or director of NEC or any of its subsidiaries
prior to the Effective Time, to the full extent permitted by applicable law.

     In addition, Sylvan has agreed that directors' and officers' liability
insurance policies maintained by NEC and its subsidiaries on the date of the
Merger Agreement will be maintained in effect until the fifth anniversary of the
Effective Time; provided, however, that Sylvan or the Surviving Corporation will
not be obligated to expend any amount per annum in excess of one hundred and
twenty-five percent (125%) of the aggregate premiums payable by NEC and its
subsidiaries in 1996 in order to maintain or procure such insurance coverage.

     APPOINTMENT OF DIRECTORS

     The Merger Agreement provides that Sylvan will use its best efforts to
cause the Sylvan Board to invite Mr. Sam Yau and three other NEC directors to
become members of the Sylvan Board, effective upon consummation of the Merger.

     NO SOLICITATION

     Pursuant to the Merger Agreement, NEC has agreed that, prior to the
Effective Time, NEC, its affiliates and their respective officers, directors,
employees, representatives and agents shall immediately cease existing
discussions or negotiations, if any, with any parties with respect to any
acquisition (other than the transactions

                                      -65-
<PAGE>
 
contemplated by the Merger Agreement or by any acquisition agreements or
negotiations described in NEC's Disclosure Statement or in its SEC reports) of
all or any material portion of the assets of, or any equity interest in, NEC or
any of its material subsidiaries or any business combination with NEC or any of
its material subsidiaries. Additionally, NEC agreed that, prior to the Effective
Time, neither NEC nor any of its affiliates nor the respective officers,
directors, employees, representatives or agents of either, will (i) solicit,
initiate, encourage, or furnish information in response to any inquiries or
proposals that constitute, or could reasonably be expected to lead to, a
proposal or offer for a merger, consolidation, business combination, sale of
substantial assets, sale of shares of capital stock (including without
limitation by way of a tender offer or similar transactions involving NEC, other
than the transactions contemplated by the Merger Agreement) (any of the
foregoing transactions being referred to as an "Acquisition Transaction"), (ii)
engage in negotiations or discussions concerning, or provide any non-public
information to any person or entity relating to, any Acquisition Transaction, or
(iii) agree to approve or recommend any Acquisition Transaction; except, with
respect to clauses (i) (as to the furnishing of information only) (ii) and
(iii), where the NEC Board has received the written opinion of Irell & Manella
LLP to the effect that the failure of the NEC Board to so act would constitute a
violation of the NEC Board's fiduciary responsibilities to the holders of the
NEC Common Stock under the DGCL (it being understood that for this purpose, the
failure to respond to an acquisition proposal which in the judgment of the NEC
Board and BZW is superior, from a financial point of view, to the NEC
stockholders may be deemed to be a breach of such fiduciary duty). The Merger
Agreement provides that if NEC shall nevertheless receive any indications of
interest or proposals with respect to any Acquisition Transactions, it shall
provide a copy of any such written proposal to Sylvan immediately after receipt
thereof by NEC or any of its representatives or agents.

     CONDITIONS PRECEDENT TO THE MERGER

     In addition to the approval of the Share Issuance by the stockholders of
Sylvan by the requisite vote under applicable law, and the approval of the
Merger Proposal by the stockholders of NEC, the obligations of NEC and Sylvan to
effect the Merger are subject to the fulfillment or waiver of certain conditions
specified in the Merger Agreement, including, among others: (i) the continuing
accuracy of the representations and warranties of the respective parties
contained in the Merger Agreement; (ii) the performance and compliance in all
material respects by the respective parties of all obligations under the Merger
Agreement required to be performed on or prior to the consummation of the
Merger; (iii) the absence of any injunction or other order by any federal or
state court preventing consummation of the Merger, (iv) the applicable period
under the HSR Act having expired or been terminated; (v) authorization of the
shares of Sylvan Common Stock issuable to NEC's stockholders for listing on
Nasdaq and the acceptance of the Listing Application by Nasdaq; (vi) the receipt
of Pooling Letters from Ernst & Young LLP and Price Waterhouse LLP and (viii)
the receipt of an opinion from Ernst & Young LLP by Sylvan and from Irell &
Manella LLP by NEC relating to the tax-free status of the Merger.

     Furthermore, the obligation of Sylvan to effect the Merger is subject to
the fulfillment or waiver of additional conditions specified in the Merger
Agreement, including (i) Sylvan shall have received all state securities or
"blue sky" permits and other authorizations necessary to issue shares of Sylvan
Common Stock pursuant to the Merger, (ii) the prior employment agreements
between NEC or any of the NEC Subsidiaries and each of Sam Yau, Anita Kopec,

entitled to any severance payments on account of the Merger, (iii) Mr. Yau shall
have entered into a replacement employment agreement which includes customary
non-compete and non-solicitation provisions, (iv) each of Messrs. Keisling and
Moran and Ms. Kopec shall have entered into replacement employment agreements in

satisfactory to Sylvan with respect to continuation of their right to benefits
under NEC's SERP Plan and other benefits theretofore provided to such

participant's employment with the Company must be terminated voluntarily or
involuntarily within two years of a change of control in order to receive
accelerated vesting and payout of SERP retirement benefits for those NEC SERP
participants who are currently active employees of NEC or a NEC subsidiary and
who otherwise would be entitled to accelerated vesting if they did terminate
their employment

                                      -66-
<PAGE>
 
within two years of a change of control, (vii) SVPC and Anita Kopec shall have
amended the option agreements between them so that the options thereunder shall
not vest as a result of the Merger, (viii) NEC shall have taken or caused to be
taken all steps and actions reasonably required by Sylvan, on advice of its
counsel, with respect to the termination or amendment of NEC Employee Plans,
including delivering notices and filing such documents as counsel to Sylvan
deems reasonably necessary and (ix) NEC shall have obtained a letter of credit,
performance bond or other substantial evidence of financial security, in each
instance in form and substance reasonably acceptable to Sylvan regarding
performance obligations of Kaleidoscope Inc. to NEC.

     TERMINATION

     The Merger Agreement may be terminated by mutual written consent of the
parties.  NEC and Sylvan each has the option to terminate the Merger Agreement
if the Average Share Price is less than the Trigger Price; provided however,
that NEC may not exercise its Termination Option if Sylvan exercises its
Adjustment Option to increase the Initial Conversion Ratio to the Adjusted
Conversion Ratio.  Assuming the number of shares of Sylvan Common Stock
outstanding on the Closing Date is no greater than the number of shares
outstanding on the Sylvan Record Date, Sylvan will not exercise its Adjustment
Option if such exercise would result in an Adjusted Conversion Ratio which is
higher than 0.5945.

     The Merger Agreement may also be terminated by either NEC or Sylvan if (i)
the Merger shall not have been consummated by September 30, 1997 (provided that
the right to terminate the Merger Agreement under this provision shall not be
available to any party whose failure to fulfill any obligation under the Merger
Agreement has been the cause of, or resulted in, the failure of the Merger to
occur on or before such date); (ii) a court of competent jurisdiction or other
governmental entity shall have issued a nonappealable final order, decree or
ruling or taken any other action, in each case having the effect of permanently
restraining, enjoining or otherwise prohibiting the Merger, except, if the party
relying on such order, decree or ruling or other action has not complied with
its obligations under the Merger Agreement; (iii) at the NEC Special Meeting
(including any adjournment or postponement thereof), the requisite vote of the
stockholders of NEC in favor of the Merger Agreement and the Merger shall not
have been obtained, or if at the Sylvan Annual Meeting (including any
adjournment or postponement thereof), the requisite vote of the stockholders of
Sylvan in favor of the Share Issuance shall not have been obtained; (iv) if
there has been a material breach of any representation, warranty, covenant or
agreement on the part of the other party set forth in the Merger Agreement,
which breach shall not have been cured in the case of a representation or
warranty, prior to the Closing or, in the case of a covenant or agreement,
within 20 business days following receipt by the breaching party of written
notice of such breach from the other party.

     Sylvan can terminate the Merger Agreement if the NEC Board shall have
withdrawn or modified its recommendation of the Merger Agreement or the Merger,
or shall have resolved to do any of the foregoing, for any reason other than the
occurrence of an event relating to Sylvan which has a Material Adverse Effect on
Sylvan, or if NEC fails to call and hold the NEC Special Meeting within forty
(40) days after the SEC declares effective the Registration Statement of which
this Joint Proxy Statement/Prospectus forms a part.

     NEC can terminate the Merger Agreement if the Sylvan Board shall have
withdrawn or modified its recommendation of the Share Issuance or shall have
resolved to do any of the foregoing, for any reason other than the occurrence of
an event relating to NEC which has a Material Adverse Effect on NEC or Sylvan
fails to call and hold the Sylvan Annual Meeting within forty (40) days after
the SEC declares effective the Registration Statement of which this Joint Proxy
Statement/Prospectus forms a part.

     TERMINATION FEE

     The Merger Agreement provides that if the Merger Agreement is terminated by
NEC due to Sylvan's failure to receive the requisite vote for approval of the
Merger Agreement and the Merger at the Sylvan Annual Meeting or if Sylvan has
materially breached any representation, warranty, covenant or agreement set
forth in the Merger Agreement, which breach shall not have been cured in the
case of a representation or warranty, prior to the

                                      -67-
<PAGE>
 
Closing Date or, in the case of a covenant or agreement, within 20 business days
following receipt by Sylvan of written notice of such breach from NEC, then
Sylvan shall pay NEC a termination fee of $10,000,000.

     In the event that the Merger Agreement is terminated by Sylvan due to (i)
NEC's Board of Directors having withdrawn or modified its recommendation of the
Merger Agreement or the Merger, or shall have resolved to do any of the
foregoing, for any reason other than the occurrence of an event relating to
Sylvan which has a Material Adverse Effect on Sylvan or (ii) NEC's failure to
call and hold the NEC Special Meeting within 40 days after the SEC declares the
S-4 effective, then NEC shall pay Sylvan a termination fee of $30,000,000.

     If Sylvan terminates the Merger Agreement (i) as a result of the failure to
receive the requisite vote for approval of the Merger Agreement and the Merger
by the stockholders of NEC at the NEC Special Meeting or (ii) after a material
breach by NEC of the Merger Agreement; then NEC shall pay Sylvan $10,000,000
provided, however, in the event that NEC shall have consummated an Acquisition
Transaction in which NEC or substantially all of its assets are acquired (even
if the acquisition is structured so that NEC or one of its subsidiaries is the
survivor in the transaction) by a party other than Sylvan or any of its
affiliates at any time on or before the expiration of eight calendar months from
Sylvan's termination under clauses (i) and (ii) above, NEC shall, or shall cause
its successor to pay Sylvan an additional amount of liquidated damages equal to
$20,000,000 for a total termination fee of $30,000,000.

     AMENDMENT; WAIVER

     The Merger Agreement may be amended by action taken by or on behalf of the
respective boards of directors of the parties thereto at any time prior to or
after the approval of the stockholders of NEC and Sylvan has been obtained, but
after such approval, no amendment shall be made which requires the further
approval of such stockholders under applicable law without such further
approval.  The Merger Agreement may not be amended except by an instrument in
writing signed on behalf of the parties thereto.

     At any time prior to the Effective Time, any of the parties to the Merger
Agreement may, to the extent permitted by applicable law: (i) extend the time
for the performance of any of the obligations or other acts of the other party;
(ii) waive any inaccuracies in the representations and warranties of the other
party thereto or in any document delivered pursuant to the Merger Agreement; or
(iii) waive compliance with any of the covenants, agreements or conditions of
the other party contained in the Merger Agreement.

     EXPENSES

     Subject to the termination fee provisions, the Merger Agreement provides
that each party thereto will pay its own expenses in connection with the Merger
except that Sylvan and NEC shall share equally all fees and expenses, other than
attorneys' fees, incurred in relation to the printing and filing of this Joint
Proxy Statement/Prospectus (including any related preliminary materials) and the
S-4 (including financial statements and exhibits) and any amendments or
supplements.  Sylvan shall pay the filing fees applicable to the S-4, and NEC
shall pay the filing fees applicable to this Joint Proxy Statement Prospectus.

DESCRIPTION OF SYLVAN CAPITAL STOCK

     GENERAL

     The authorized capital stock of Sylvan consists of 50,000,000 shares,
40,000,000 of which are classified as Common Stock, $.01 par value, and
10,000,000 of which are classified as preferred stock, par value $.01 per share,
with 250,000 shares designated as Series A Junior Participating Preferred Stock.
If the Common Shares Amendment is adopted at the Sylvan Annual Meeting, and
Articles of Amendment are filed with the Maryland State Department of
Assessments and Taxation (the "SDAT"), the number of shares of authorized Sylvan
Common Stock will increase to 90,000,000 shares.  If the Preferred Shares
Amendment is adopted at the Sylvan Annual Meeting 

                                      -68-
<PAGE>
 
and Articles Supplementary are filed with the SDAT, the number of shares of
Preferred Stock designated as Series A Junior Participating Preferred Stock will
increase to 400,000 shares. As of the Sylvan Record Date, __________ shares of
Sylvan Common Stock were outstanding and held of record by ______ stockholders.
There were no shares of Preferred Stock outstanding on the Sylvan Record Date.

     COMMON STOCK

     Holders of Sylvan Common Stock are entitled to one vote for each share held
of record on all matters on which stockholders are entitled to vote.  There are
no cumulative voting rights and holders of Sylvan Common Stock have no
preemptive rights.  All issued and outstanding shares of Sylvan Common Stock are
validly issued, fully paid and non-assessable.  Holders of Common Stock are
entitled to such dividends as may be declared from time to time by the Sylvan
Board out of funds legally available for that purpose.  Upon liquidation,
dissolution or winding up, whether voluntary or involuntary, holders of Sylvan
Common Stock are entitled to share pro rata in the assets of Sylvan remaining
after payment in full of all its liabilities and obligations, including payment
of the liquidation preference, if any, of any preferred stock then outstanding.

     PREFERRED STOCK

     Blank Check Preferred Stock.  The Sylvan Board, without further action by
the stockholders, is authorized to issue preferred stock in one or more series
and to designate as to any such series the preferences, conversion or other
rights, voting powers, restrictions, limitations as to dividends,
qualifications, or terms or conditions of redemption.  The rights of the holders
of Sylvan Common Stock will be subject to, and may be adversely affected by, the
rights of the holders of any preferred stock that may be issued in the future.
Issuance of a new series of preferred stock, while providing desirable
flexibility in connection with possible acquisitions or other corporate
purposes, could have the effect of making it more difficult for a third party to
acquire, or of discouraging a third party from acquiring, a majority of the
outstanding voting stock of Sylvan.  Sylvan has no present plans to issue any
new series of preferred stock.

     Series A Junior Participating Preferred Stock.  Holders of Series A Junior
Participating Preferred Stock ("Series A Preferred Stock") are entitled to
receive in preference to holders of Sylvan Common Stock and of any other junior
stock, when, as and if declared by the Sylvan Board, quarterly cash dividends,
if such dividends are in arrears for six consecutive quarters, holders of Series
A Preferred Stock may remove two members of the Sylvan Board and elect their
replacements.  Each share of Series A Preferred Stock is entitled to 100 votes
on all matters submitted to a shareholder vote, voting together as a single
class with holders of Sylvan Common Stock.  Upon liquidation, dissolution or
winding up, holders of Series A Preferred Stock shall receive $100 per share
plus accrued and unpaid dividends, provided that such holders are entitled to
receive an aggregate amount per share equal to 100 times the aggregate amount to
be distributed to holders of priority stock or Sylvan Common Stock, subject to
adjustment in certain circumstances.  If Sylvan should consolidate, merge, or
enter into any other transaction in which shares of Sylvan Common Stock are
exchanged for or changed into other consideration, the Series A Preferred Stock
shall be similarly exchanged or changed in an amount per share equal to 100
times such consideration.  The Series A Preferred Stock ranks junior to all
other Sylvan Preferred Stock unless the terms of such other Sylvan Preferred
Stock provide otherwise.

     BUSINESS COMBINATIONS AND CONTROL SHARE ACQUISITION PROVISIONS OF MARYLAND
     GENERAL CORPORATION LAW

     Section 3-602 of the MGCL provides that, subject to certain exceptions
specified therein, any holder of 10% or more of the voting stock of a Maryland
corporation after the corporation has 100 or more beneficial owners (an
"interested stockholder") may not engage in any business combination with the
corporation for a five-year period following the date that such stockholder
becomes an interested stockholder unless prior to such date, the board of
directors of the corporation approved the 10% acquisition.  After such five-year
period, any such business combination must be recommended by the board of
directors of the corporation and approved by the affirmative 

                                      -69-
<PAGE>
 
vote of at least 80% of the outstanding voting stock and 662/3% of the
outstanding voting stock which is not owned by the interested stockholder,
unless certain fair price and other conditions are met. Under certain
circumstances, Section 3-602 makes it more difficult for a person who would be
an interested stockholder to effect various business combinations with a
corporation for a five-year period. Such provisions could make it more difficult
to accomplish transactions which Sylvan's stockholders may otherwise deem to be
in their best interests. Such provisions may also have the effect of preventing
changes in the management of Sylvan.

     Subtitle 7 of Title 3 of the MGCL provides that "control shares" of a
Maryland corporation acquired in a "control share acquisition" have no voting
rights except to the extent approved by a vote of two-thirds of the votes
entitled to be cast on the matter, excluding shares of stock owned by the
acquiror or by the officers or directors who are also employees of the
corporation.  Control shares are voting shares of stock which, if aggregated
with all other shares of stock previously acquired by such a person, would
entitle the acquiror to exercise voting power in electing directors within one
of the following ranges of voting power: (i) 20% or more but less than 33 1/3%;
(ii) 33 1/3% or more but less than a majority; or (iii) a majority of all voting
power.  Control Shares do not include shares of stock an acquiring person is
entitled to vote as a result of having previously obtained stockholder approval.
A control share acquisition means, subject to certain exceptions, the
acquisition of, ownership of or the power to direct the exercise of voting power
with respect to, control shares.

     A person who has made or proposes to make a control share acquisition, upon
satisfaction of certain conditions (including an undertaking to pay expenses),
may compel the board of directors to call a special meeting of stockholders to
be held within 50 days of demand therefor to consider the voting rights of the
shares.  If no request for a meeting is made, the corporation may itself present
the question at any stockholders' meeting.  Subject to certain conditions and
limitations, the corporation may redeem any or all of the control shares (except
those for which voting rights have previously been approved) for fair value
determined, without regard to the absence of voting rights, as of the date of
the last control share acquisition by the acquiring person or of any meeting of
stockholders at which the voting rights of such shares are considered.  If
voting rights for control shares are approved at a stockholders' meeting and the
acquiror becomes entitled to vote a majority of the shares entitled to vote, all
other stockholders may exercise appraisal rights.  The fair value of the stock
as determined for purposes of such appraisal rights may not be less than the
highest price per share paid in the control share acquisition, and certain
limitations and restrictions otherwise applicable to the exercise of objecting
stockholders' rights do not apply in the context of a control share acquisition.

     The control share acquisition statute does not apply to stock acquired in a
merger, consolidation or stock exchange if the corporation is a party to the
transaction, or to acquisitions previously approved or exempted by a provision
in the Charter or By-Laws of the corporation.  The application of the Control
Share Acquisition Statute to Sylvan could have the effect of discouraging offers
to acquire Sylvan and of increasing the difficulty of consummating any such
offer.

     LIMITATIONS ON CHANGE OF CONTROL

     Sylvan is a party to certain employment agreements, each of which contain
provisions with respect to a change in control of Sylvan.  In addition, certain
provisions of Sylvan's Charter may inhibit changes in control of Sylvan.  See
"PROPOSAL I: THE SHARE ISSUANCE AND THE MERGER--Description Of Sylvan Capital
Stock--Limitations on Change of Control" and "RISK FACTORS--Potential Effects of
Certain Anti-Takeover Provisions."

     TRANSFER AGENT

     Boston EquiServ is the Registrar and Transfer Agent for Sylvan Common
Stock.

COMPARATIVE RIGHTS OF STOCKHOLDERS OF SYLVAN AND NEC

     Upon consummation of the Merger, the stockholders of NEC, a Delaware
corporation, will become stockholders of Sylvan, a Maryland corporation.
Accordingly, the rights of stockholders of NEC following the Merger will be
governed by Maryland law, as well as the Sylvan Amended and Restated Charter and
Amended & Restated By-Laws.

     The following is a summary of the material differences between the rights
and privileges of NEC stockholders and those of Sylvan stockholders.  References
to the "DGCL" are to the General Corporation Law of Delaware, while references
to the "MGCL" are to the General Corporation Law of Maryland.  This summary is
not meant to be relied upon as an exhaustive description of such differences and
is qualified in its entirety by reference to the Sylvan Amended and Restated
Charter (the "Sylvan Charter") and Amended & Restated By-Laws, the NEC Restated
Certificate of Incorporation (the "NEC Charter") and By-Laws, the DGCL and the
MGCL.

     ACTION BY WRITTEN CONSENT OF STOCKHOLDERS

     Sylvan.  Consistent with Sylvan's By-Laws, any action required or permitted
to be taken at a meeting of stockholders may be taken without a meeting if all
stockholders entitled to vote consent to the action in writing and any
stockholder entitled to notice of the meeting but not entitled to vote at the
meeting provides a written waiver of any right to dissent.

     NEC.  Under the NEC Charter, any action required or permitted to be taken
by the stockholders must be taken at an annual or special meeting of
stockholders and may not be taken by consent in writing.

     AMENDMENT OF CHARTER DOCUMENTS AND BY-LAWS

     Sylvan.  Under the MGCL, unless otherwise provided in a corporation's
charter, a proposed charter amendment requires an affirmative vote of two-thirds
of all the votes entitled to be cast on the matter.  However, the Sylvan Charter
provides that the affirmative vote of the holders of a majority of the total
number of shares of outstanding Sylvan stock entitled to vote thereon is
sufficient to amend the Sylvan Charter.  Under the MGCL, the power to adopt,
alter, and repeal the by-laws is vested in the stockholders, except to the
extent that the charter or the by-laws vest such power in the board of
directors.  The Sylvan By-Laws provide that they may be amended by the Sylvan
Board without the approval or consent of the stockholders, but shall be subject
to repeal by the affirmative vote of the holders of a majority of the common
stock then entitled to vote and may be amended by the stockholders by the
affirmative vote of the holders of a majority of the common stock then entitled
to vote.

     NEC.  The DGCL provides that an amendment to a corporation's certificate of
incorporation requires the recommendation of the corporation's board of
directors, the approval of a majority of all shares entitled to vote thereon
unless a higher vote is required in the corporation's certificate of
incorporation, voting together as a single class, and the approval of a majority
of the outstanding stock of each class entitled to vote thereon.  Article 11 of
NEC's Charter, relating to certain business combinations, may only be amended by
the affirmative vote of the holders of NEC capital stock representing 75% of all
votes entitled to be cast in the election of directors.  The NEC By-Laws may be
amended by a majority of the whole NEC Board and may also be amended by the
affirmative vote of the holders of not less than two-thirds of the issued and
outstanding shares of NEC.

     BUSINESS COMBINATIONS

     Sylvan.  Generally, under the MGCL, the approval by the affirmative vote of
two-thirds of all the votes entitled to be cast on the matter is required for
mergers, consolidations, share exchanges, and any transfers of all or
substantially all of the assets of a corporation, unless the charter increases
or reduces the vote to not less than a majority.  The Sylvan Charter alters the
two-thirds vote requirement by providing that the affirmative vote of the
holders of a majority of the total number of shares of outstanding Sylvan stock
entitled to vote thereon is sufficient.

                                      -71-
<PAGE>
 
     Subtitle 6 of Title 3 of the MGCL prohibits any business combination
(defined to include a variety of transactions, including mergers,
consolidations, share exchanges, sales or dispositions of assets, issuances of
stock, liquidations, reclassification and benefits from the corporation,
including loans or guarantees) between a Maryland corporation and any interested
stockholder (defined generally as any person who, directly or indirectly,
beneficially owns 10% or more of the outstanding voting stock of the
corporation) for a period of five years after the date in which the interested
stockholder became an interested stockholder.  After such five-year period, a
business combination between a Maryland corporation and such interested
stockholder is prohibited unless either certain "fair-price" provisions are
complied with or the business combination is approved by certain supermajority
stockholder votes.  The MGCL restrictions do not apply to a business combination
with an interested stockholder if such business combination is approved or
exempted from the MGCL by a resolution of the board of directors adopted prior
to the date on which the interested stockholder became an interested
stockholder.  The Sylvan Board did not adopt such a resolution prior to the
execution of the Merger Agreement [confirm this].

     A Maryland corporation also may adopt an amendment to its charter electing
not to be subject to the business combination provisions of the MGCL in whole or
in part.  Any such amendment generally must be approved by the affirmative vote
of at least 80% of the votes entitled to be cast by all holders of outstanding
shares of voting stock and two-thirds of the votes entitled to be cast by
holders of outstanding shares of voting stock who are not interested
stockholders.  No such amendment to the Sylvan Charter has been adopted.

     NEC.  Section 203 of the DGCL ("Section 203") prohibits a Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" (as defined below) for three years following the time that such
person becomes an interested stockholder.  With certain exceptions, an
interested stockholder is a person or group who or which owns 15% or more of the
corporation's outstanding voting stock (including any rights to acquire stock
pursuant to an option, warrant, agreement, arrangement or understanding, or upon
the exercise of conversion or exchange rights, and stock with respect to which
the person has voting rights only), or is an affiliate or associate of the
corporation and was the owner of 15% or more of the corporation's voting stock
at any time within the previous three years.

     For purposes of Section 203, the term "business combination" is defined
broadly to include mergers with or caused by the interested stockholder; sales
or other dispositions to the interested stockholder (except proportionately with
the corporation's other stockholders) of assets of the corporation or a
subsidiary equal to 10% or more of the aggregate market value of the
corporation's consolidated assets or its outstanding stock; the issuance or
transfer by the corporation or a subsidiary of stock of the corporation or such
subsidiary to the interested stockholder (except for transfers in a conversion
or exchange or a pro rata distribution or certain other transactions, none of
which increase the interested stockholder's proportionate ownership of any class
or series of the corporation's or such subsidiary's stock); and receipt by the
interested stockholder (except proportionately as a stockholder), directly or
indirectly, of any loans, advances, guarantees, pledges or other financial
benefits provided by or through the corporation or a subsidiary.

     The three-year moratorium imposed on business combinations by Section 203
does not apply if: (i) prior to the time on which such stockholder becomes an
interested stockholder the board of directors approves either the business
combination or the transaction which resulted in the person becoming an
interested stockholder, (ii) the interested stockholder owns 85% of the
corporation's voting stock upon consummation of the transaction which made him
an interested stockholder (excluding shares held by certain affiliates of the
corporation and certain employee stock plans); or (iii) at or subsequent to the
time such person becomes an interested stockholder, the business combination is
approved by both the board of directors and 66 2/3% of the outstanding voting
stock of the corporation (excluding shares held by the interested stockholder).

     Section 203 only applies to Delaware corporations which have a class of
voting stock that is listed on a national securities exchange, is quoted on
Nasdaq or is held of record by more than 2,000 stockholders.  A Delaware
corporation may elect in its original certificate of incorporation, or by
amending its certificate of incorporation or bylaws, that it will not be
governed by Section 203.  Any such amendment must be approved by the
stockholders 

                                      -72-
<PAGE>
 
and, in the case of a bylaw amendment, may not be further amended by the board
of directors. NEC is subject to the provisions of Section 203 and has not
elected to opt out from being governed by Section 203.

     APPRAISAL RIGHTS

     Sylvan.  Under the MGCL, except as otherwise provided by the MGCL,
objecting stockholders have the right to demand and receive payment of the "fair
value" of their stock in the event of (i) a merger or consolidation, (ii) a
share exchange, (iii) a transfer of all or substantially all assets not in the
ordinary course of business, (iv) an amendment to the charter which alters the
contract rights, as expressly set forth in the charter, of any outstanding stock
and which substantially adversely affects the stockholder's rights, unless the
right to do so is preserved by the charter (which it is not, in the case of
Sylvan), (v) certain business combinations or (vi) after an approval by the
stockholders of voting rights for control shares which constitute a majority of
the voting power of the corporation.  However, except as otherwise provided by
the MGCL, stockholders do not have appraisal rights if, among other things, the
stock is listed on a national securities exchange: (i) with respect to a merger
of a 90% or more owned subsidiary into its parent, on the date notice of such
merger is given or waived, or (ii) with respect to any other transaction, on the
record date for determining stockholders entitled to vote on the transaction.

     NEC.  The DGCL provides for dissenters' appraisal rights only in the case
of a statutory merger or consolidation of the corporation where the petitioning
stockholder has neither voted in favor of nor consented in writing to the
transaction.  In addition, under DGCL Section 262, no dissenters' appraisal
rights are available where the corporation is to be the surviving corporation
and a vote of its stockholders is not required under DGCL Section 251(f).  There
are no dissenters' appraisal rights for shares of stock listed on a national
securities exchange or designated as a national market system security on an
interdealer quotation system or held by more than 2,000 holders of record,
unless such stockholders would be required to accept anything other than shares
of stock of the surviving corporation, shares of another corporation so listed
or designated or held by such number of holders of record, cash in lieu of
fractional shares of such stock or any combination thereof.

     PREEMPTIVE RIGHTS

     Neither NEC nor Sylvan stockholders have preemptive rights with respect to
issuances of capital stock.

     INDEMNIFICATION

     Sylvan.  Under the MGCL, a corporation may indemnify any director or
officer made a party to any proceeding unless it is established that (i) the
director's or officer's act or omission was material to the cause of action and
was committed in bad faith or resulted from active and deliberate dishonesty,
(ii) the director or officer actually received an improper personal benefit in
money, property or services, or (iii) in the case of criminal proceedings, the
director or officer had reasonable cause to believe the act or omission was
unlawful.  The Sylvan Charter provides that Sylvan will indemnify its directors
and its officers to the full extent required or permitted by Maryland law.

     The MGCL states that a determination must be made that a director or
officer has met the required standard of conduct before the director or officer
may be indemnified.  The determination may be made by a majority vote of
disinterested directors, by special legal counsel (selected by the disinterested
directors) or by the stockholders.

     The MGCL also establishes several mandatory rules requiring and prohibiting
indemnification.  A director or officer who is successful, on the merits or
otherwise, in any proceeding must be indemnified by the corporation for
reasonable expenses (including attorneys' fees).  In a stockholder derivative
suit, a corporation may not indemnify a director or officer if he or she is
adjudged liable to the corporation.  Moreover, a corporation may not indemnify a
director or officer who is adjudged to be liable, in any proceeding, for a
personal benefit that was improperly received.

                                      -73-
<PAGE>
 
     The MGCL permits a corporation to advance reasonable expenses to directors
and officers upon the director's or officer's written affirmation of his or her
good faith belief that he or she has met the required standard of conduct and
after undertaking to repay the corporation if it is determined that the standard
has not been met.  Under the Sylvan Charter, a director or officer is entitled
to payment of expenses in advance of the final disposition of a proceeding to
the full extent permitted by Maryland law.

     NEC.  Section 145 of the DGCL authorizes a Delaware corporation to
indemnify any person who was, is, or is threatened to be made, a party in any
civil, criminal, administrative or investigative threatened, pending or
completed action, suit or proceeding (other than an action by or in the right of
a corporation) by reason of the fact that he is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another entity, for
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by such person in connection with
any threatened, pending or completed action, suit or proceeding.  With respect
to actions by or in the right of a corporation, the DGCL authorizes
indemnification of such person for expenses (including attorneys' fees) actually
and reasonably incurred by him in connection with the defense or settlement of
such action or suit.  To be entitled to indemnification, a person must have
acted in good faith and in a manner he or she reasonably believed to be in, or
not opposed to, the best interests of the corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe such conduct
was unlawful.  With respect to actions by or in the right of the corporation,
court approval is required for indemnification relating to any claim as to which
a person has been adjudged liable to the corporation.

     The DGCL requires indemnification for expenses actually and reasonably
incurred by any director, officer, employee or agent in connection with a
proceeding against such person for actions in such capacity to the extent that
the person has been successful on the merits or otherwise.  Advancement of
expenses is permitted, but not required, by the DGCL.  A director or officer
must undertake to repay such expenses if it is ultimately determined that he or
she is not entitled to indemnification.  The disinterested members of the board
(or independent legal counsel or stockholders) must determine, in each instance
where indemnification is not required by the DGCL, that such director, officer,
employee or agent is entitled to indemnification.  The DGCL provides that the
statutory indemnification is not exclusive.

     The NEC By-Laws  provide for indemnification of officers and directors as
permitted by Section 145 of the DGCL provided that such proceeding for which
indemnification is sought was authorized by the NEC Board of Directors.  NEC has
also entered into Indemnification Agreements with its officers and directors
providing for indemnification to the maximum extent permitted by law.

     LIMITATION OF PERSONAL LIABILITY OF DIRECTORS

     Sylvan.  The MGCL provides that a corporation's charter may include a
provision eliminating or limiting the personal liability of a director or
officer to the corporation or its stockholders for money damages except (i) to
the extent that it is proved that the person actually received an improper
benefit or profit in money, property or services, for the amount of the benefit
or profit in money, property, or services actually received or (ii) to the
extent that a court finds that the person's action, or failure to act, was the
result of active and deliberate dishonesty and was material to the cause of
action adjudicated in the proceeding.  The Sylvan Charter provides that its
directors and officers shall have no personal liability to Sylvan or its
stockholders for money damages to the fullest extent permitted by Maryland law.

     NEC.  Section 102(b)(7) of the DGCL allows a Delaware corporation to limit
or eliminate the personal liability of directors to a corporation and its
stockholders for monetary damages for breach of fiduciary duty as a director
subject to certain limitations.  The NEC Charter provides for the limitation of
liability as permitted by Section 102(b)(7) of the DGCL.

                                      -74-
<PAGE>
 
     CLASSIFIED BOARD OF DIRECTORS

     Sylvan.  The MGCL permits, but does not require, a classified board of
directors.  The Sylvan Charter and By-Laws provide for three classes of
directors, with each class elected for a term of three years and consisting, as
nearly as possible, of one-third of the total number of directors on the Board.
The Sylvan By-Laws provide that Sylvan shall have nine directors, a number which
may be amended in accordance with the By-Laws or Charter.  At each annual
meeting of Sylvan stockholders one class of directors is elected for a three-
year term.  Classification of directors has the effect of making it more
difficult for stockholders to change the composition of a board of directors.
At least two annual meetings of stockholders, instead of one, will generally be
required to effect a change in the majority of a classified board.  Such a delay
may help ensure that incumbent directors, if confronted by a holder attempting
to force a proxy contest, a tender or exchange offer or other extraordinary
corporate transaction, would have sufficient time to review the proposal as well
as any available alternatives to the proposal and to act in what they believe to
be the best interests of the stockholders.  On the other hand, the
classification of directors may delay, defer or prevent a takeover attempt that
a stockholder might consider in its best interest.  If the Directors Amendment
is approved at the Sylvan Annual Meeting, Sylvan directors will serve one-year
terms and the Sylvan Board of Directors will no longer be classified.

     NEC.  The DGCL permits, but does not require, a classified board of
directors.  The NEC Board is divided into three classes, with each class elected
for a term of three years and consisting, as nearly as possible, of one-third of
the total number of directors on the Board.  The NEC By-laws provide that NEC
shall have ten directors, a number which may be amended by the Board of
Directors.  Currently, pursuant to NEC Board resolutions, NEC has 11 directors.

     CUMULATIVE VOTING FOR DIRECTORS

     Neither NEC nor Sylvan uses cumulative voting in the election of directors.

     REMOVAL OF DIRECTORS

     Sylvan.  Under the MGCL, except as otherwise provided in a corporation's
charter or by-laws, the stockholders generally may remove any director, with or
without cause, by the affirmative vote of a majority of all the votes entitled
to be cast for the election of the directors.  The Sylvan By-Laws provide that a
director may only be removed for cause.

     NEC.  Under the DGCL, the affirmative vote of a majority of the shares
entitled to vote at the election of directors is required to remove directors,
with or without cause.

     NEWLY CREATED DIRECTORSHIPS AND VACANCIES

     Sylvan.  Consistent with the MGCL, the Sylvan By-Laws provide that any
vacancy on the Board of Directors may be filled by vote of a majority of the
remaining directors then in office, although less than a quorum, or by a sole
remaining director or by the stockholders, if not filled by the directors.  Any
vacancy on the Board of Directors that results from an increase in the number of
directors may be filled only by the stockholders at an annual meeting or a
special meeting called for that purpose.  Any director elected by the directors
then in office to fill a vacancy shall serve until the next annual meeting of
stockholders, and until his successor is elected and qualifies.  A director
elected by the Board of Directors to fill a vacancy serves until the next annual
meeting of stockholders and until his successor is elected and qualified.  A
director elected by the stockholders to fill a vacancy which results from the
removal of a director serves for the balance of the term of the removed
director.

     NEC.  If the position of any director of NEC is or becomes vacant or if the
number of directors shall be increased, a majority of the directors of NEC
remaining in office, although less than a quorum or the stockholders may fill
the vacancy or newly created directorship.  Any director chosen shall hold
office until the next election of 

                                      -75-
<PAGE>
 
the class for which such direction shall have been chosen, and until his
successor shall be elected and qualified. If the Board is expanded, the new
positions shall be allocated among the various classes of directors, so that
such classes shall remain as nearly equal in number as possible.

     SPECIAL MEETINGS

     Sylvan.  The Sylvan By-Laws provide that special meetings of stockholders
may be called by the Board of Directors, the President, the Chief Executive
Officer, or by the Secretary upon the written request of stockholders entitled
to cast at least 25% of all votes entitled to be cast at the meeting.

     NEC.  A special meeting of stockholders of NEC may be called by the Chief
Executive Officer, and shall be called by the Chief Executive Officer, the
Chairman of the Board, or Secretary upon the order of the Board.

     INSPECTION RIGHTS

     Sylvan.  Under the MGCL any stockholder has the right to inspect and copy
by-laws, minutes of stockholder proceedings, annual statements of affairs,
voting trust agreements on file, and statements showing all stock and securities
issued by the corporation during a specified period of not more than twelve
months before the date of the request.  In addition, one or more persons who
together are and for at least the last six (6) months have been stockholders of
record of at least 5% of the outstanding stock of any class may inspect and copy
the corporation's books of account and stock ledger.

     NEC.  Under the DGCL, any stockholder, following a written request, has the
right to inspect and copy the corporation's books and records, including the
stock ledger and stockholder list, during normal business hours for a proper
purpose reasonably related to such person's interest as a stockholder.

     DIVIDENDS AND DISTRIBUTIONS

     Sylvan.  Under the MGCL, a board of directors may authorize a corporation
to make distributions to its stockholders, subject to any restrictions in its
charter and as provided under the MGCL.  Under the MGCL, no distribution is
permitted, however, if, after giving effect to the distribution, the corporation
would not be able to pay its indebtedness as the indebtedness becomes due in the
ordinary course of business or the corporation's total assets would be less than
the sum of its total liabilities plus, unless the charter permits otherwise, the
amount needed, if the corporation were to be dissolved at the time of the
distribution, to satisfy the preferential rights upon dissolution of
stockholders whose preferential rights on dissolution are superior to those
receiving the distribution.

     NEC.  The DGCL provides that, subject to any restrictions in a
corporation's certificate of incorporation, dividends may be declared from a
corporation's surplus or, if there is no surplus, from its net profits for the
fiscal year in which the dividend is declared and the preceding fiscal year.
However, if the corporation's capital (generally defined in the DGCL as the sum
of the aggregate par value of all shares of the corporation's capital stock,
where all such shares have a par value and the board of directors has not
established a higher level of capital) has been diminished to an amount less
than the aggregate amount of the capital represented by the issued and
outstanding stock of all classes having a preference upon the distribution of
assets, dividends may not be declared and paid out of such net profits until the
deficiency in such capital has been repaired.

     RIGHTS AGREEMENT

     Sylvan.  On September 27, 1996, the Sylvan Board adopted the Rights
Agreement dated October 7, 1996.  The "Rights" provided for thereunder represent
the right to purchase one-hundredth of a share of Series A Junior Participating
Preferred Stock, par value $.01 per share, of Sylvan.

     NEC.  NEC does not have a shareholder rights or similar plan.

                 PROPOSALS II, III AND IV:  CHARTER AMENDMENTS

     On _____________, 1997, the Sylvan Board unanimously approved a resolution
to amend the Sylvan Charter to increase the number of authorized shares of
Sylvan Common Stock from 40,000,000 shares to 90,000,000 shares, to increase
from 250,000 to 400,000 the number of shares of Preferred Stock designated as
Series A Junior Preferred Stock and to amend the Sylvan Charter to decrease the
term served by directors from three years to one year and eliminating classes of
directors.  Sylvan has currently authorized 50,000,000 shares of capital stock,
of which 40,000,000 are classified as common stock and 10,000,000 are classified
as preferred stock.  If the Shares Amendment is approved, Sylvan would be
authorized to issue up to 90,000,000 shares of common stock.

COMMON SHARES AMENDMENT

     The Common Shares Amendment would revise Article Fifth of the Sylvan
Charter to read, in its entirety, as follows:

          "The total number of shares of stock of all classes which the
     Corporation has authority to issue is 100,000,000 shares, having an
     aggregate par value of $1,000,000, of which 90,000,000 shares, par value of
     $.01 per share, amounting in aggregate par value to $900,000, shall be
     Common Stock, and 10,000,000 shares, par value of $.01 per share, amounting
     in aggregate par value to $100,000, shall be Preferred Stock."

     The increase in the number of authorized shares of Sylvan Common Stock will
provide additional shares for issuance, without the delay and expense of further
stockholder approval at such time or times and for such proper corporate
purposes as the Sylvan Board may in the future deem advisable.  Such shares may
be issued if and when the Sylvan Board decides it is in the best interest of
Sylvan to do so which may include, without limitation, issuances (i) as part of
an acquisition transaction (as in the case of the Merger); (ii) to obtain funds
through the sale of Sylvan Common Stock; (iii) to declare a stock split or stock
dividend; (iv) in respect of the 1993 Plan, the Management Plan or other
employee benefit or stock plan; or (v) for other purposes.  Unless required by
applicable law, the rules of Nasdaq, the Sylvan Charter or the Sylvan By-Laws,
it is not anticipated that Sylvan will solicit the votes of stockholders prior
to the issuance of Sylvan Common Stock for any of the purposes described above.

PREFERRED SHARES AMENDMENT

     The Shares Amendment would revise Article Second of the Articles
Supplementary of the Sylvan Charter to read, in its entirety, as follows:

          "1.  Designation and Amount.  The shares of such series shall be
               ----------------------
     designated as "Series A Junior Participating Preferred Stock" (the "Series
     A Preferred Stock") and the number of shares constituting such series shall
     be 400,000, subject to increase or decrease by action of the Board of
     Directors effectuated by further Articles Supplementary."

DIRECTORS AMENDMENT

     The Directors Amendment would revise Article Seventh of the Sylvan Charter
to read, in its entirety, as follows:

          "The number of directors of the Corporation shall be seven, which
     number may be increased or decreased pursuant to the Charter of the
     Corporation or the By-Laws of the Corporation, but shall never be less than
     the minimum number permitted by the General Laws of the State of Maryland
     now or hereafter in force."

       THE SYLVAN BOARD UNANIMOUSLY RECOMMENDS THAT SYLVAN STOCKHOLDERS
                   VOTE FOR EACH OF THE CHARTER AMENDMENTS.

                     PROPOSALS V AND VI:  PLAN AMENDMENTS

1993 PLAN AMENDMENT

     The Sylvan Board of Directors, pursuant to the recommendation of its
Compensation Committee, amended the 1993 Employee Stock Option Plan (the "1993
Plan") after the 1996 Annual Meeting on July 13, 1996, September 27, 1996, and
March 6, 1997, to increase the number of shares of Common Stock available for
award thereunder by 150,000, 225,000 and 200,000 shares, respectively
(collectively, the "1993 Plan Amendment").  Before these three amendments, the
total number of shares for award thereunder authorized under the 1993 Plan was
2,625,000 shares and, upon approval of the 1993 Plan Amendment, will be
5,200,000 shares.  As of the Sylvan Record Date, options for ______________
shares were outstanding under the 1993 Plan.  The Compensation Committee
recommended the increases for the primary purpose of rewarding key employees for
past performance and giving key employees, including those joining Sylvan as new
hires as a result of the Merger, acquisitions or otherwise, incentive to perform
at a high standard in the future.

     All full-time employees, including executive officers, of Sylvan are
eligible to participate in the 1993 Plan.  The Compensation Committee determines
which of the eligible employees should receive options and, in the Committee's
discretion associated stock appreciation rights, under the 1993 Plan based on
certain performance criteria determined by the Compensation Committee.  In
addition, the Compensation Committee determines the type of option (incentive or
non-qualified, or both) to be granted, the number of shares subject to each
option, the rate of option exercisability and, subject to certain provisions,
the option price and duration of the option.  The per share exercise price for
options granted under the 1993 Plan must be equal to at least 100% of the per
share fair market value of the Common Stock underlying the options on the date
of grant.  The options granted under the 1993 Plan can be exercised through
payment of cash, or by a cashless exercise or a combination of both.  On the
Sylvan Record Date, the aggregate market value of the ______________ shares of
Common Stock underlying outstanding options on that date under the 1993 Plan was
$_____________.

     On the Sylvan Record Date, employees who were not executive officers of
Sylvan held ____________ of the ________ options outstanding at that date under
the 1993 Plan, with executive officers holding the remaining options outstanding
on that date.

MANAGEMENT PLAN AMENDMENT

     The Sylvan Board of Directors, pursuant to the recommendation of its
Compensation Committee, amended the 1996 Senior Management Stock Option Plan
(the "Management Plan") on April __, 1997, to increase the number of shares of
Common Stock available for award thereunder by ___________ shares, the
"Management Plan Amendment"). Before the Management Plan Amendment, the total
number of shares for award thereunder authorized under the Management Plan was
2,250,000 shares and, upon approval, will be 3,250,000 shares. Pursuant to the
Management Plan, stock options may be granted which qualify under the Internal
Revenue Code as incentive stock options as well as stock options that do not
qualify as incentive stock options. Only Sylvan's Co-Chief Executive Officers
and Chairman of the Board, Chief Financial Officer, and other Senior Executive
Officers, currently a total of three individuals (and after the Merger a total
of seven individuals), are eligible to receive options under the Management
Plan. On _____________, 1997, the Board of Directors granted to the Co-Chief
Executive Officers and Chief Financial Officer _______, _______________ and
_____________ options, respectively under the Management Plan. As of the Sylvan
Record Date, options for ______________ shares were outstanding under the
Management Plan at a weighted average exercise price of $______ per share. The
Compensation Committee recommended the increases for the primary purpose of
rewarding Sylvan's senior executive officers for past performance and giving
them incentive to perform at a high standard in the future.

     The Compensation Committee determines which of the eligible employees
should receive options and, in the Compensation Committee's discretion
associated stock appreciation rights, under the Management Plan based on

                                      -78-
<PAGE>
 
certain performance criteria determined by such Committee. In addition, the
Compensation Committee determines the type of option (incentive or non-
qualified, or both) to be granted, the number of shares subject to each option,
the rate of option exercisability and, subject to certain provisions, the option
price and duration of the option. The per share exercise price for incentive
stock options granted under the Management Plan must be equal to at least 100%
of the per share fair market value of the Common Stock underlying the options on
the date of grant. The option price for non-qualified options granted under the
Management Plan must be equal to at least 85% of the fair market value of the
Sylvan Common Stock as of the date the option is granted. The options granted
under the Management Plan can be exercised through payment of cash, or by a
cashless exercise or a combination of both. The Sylvan Board has interpreted the
terms of the Management Plan allowing payment of the option price in Sylvan
Common Stock to permit "pyramiding" of shares in successive exercises. On the 
Sylvan Record Date, the aggregate market value of the 1,035,000 shares of Common
Stock underlying outstanding options on that date under the Management Plan was 
$ ______________.

INTERESTS OF CERTAIN PERSONS IN THE PLAN AMENDMENTS

     Except as set forth on the table below, awards under the 1993 Plan and the
Management Plan will be granted at the sole discretion of the Compensation
Committee of the Sylvan Board of Directors and performance criteria, if any, may
vary from year to year and from participant to participant.  Therefore, benefits
under the 1993 Plan and the Management Plan are generally not determinable.  In
the event that the Management Plan Amendment is approved at the Sylvan Annual
Meeting, the following table sets forth certain information regarding stock
option grants that Sylvan has agreed to make pursuant to employment contracts
with certain NEC executive officers:

INFORMATION REGARDING THE SYLVAN BOARD, COMMITTEES AND REMUNERATION

     During calendar year 1996, there were seven meetings of the Board of
Directors of Sylvan.  Each director attended at least 80% of the combined total
number of meetings of the Board and Board committees of which he was a member
except for Richard P. Campbell who attended two meetings prior to his
resignation.  The Sylvan Board has an Audit Committee and a Compensation
Committee.

     The Audit Committee meets with Sylvan's independent accountants to review
whether satisfactory accounting procedures are being followed by Sylvan and
whether its internal accounting controls are adequate, to monitor non-audit
services performed by the independent accountants and review fees charged by the
independent accountants.  The Audit Committee also recommends to the Board of
Directors the selection of independent accountants.  During 1996, non-employee
directors, Richard P. Campbell, Jr., G. Cook Jordan, Jr. and Patrick A. Hopf,
were the members of the Audit Committee.  Messrs. Samper and McGuire replaced
Messrs. Campbell and Jordan upon their resignations from the Sylvan Board during
1996.  There were three meetings of the Committee during fiscal year 1996.

     The Compensation Committee establishes the compensation for executive
officers of Sylvan and generally reviews benefits and compensation for all
officers and employees.  It also administers Sylvan's stock option plans.
During 1996, non-employee directors, Richard P. Campbell, Jr., J. Phillip
Samper, and Donald V. Berlanti, were the members of the Compensation Committee,
which met on two occasions.  The report of the Compensation Committee required
by the rules of the Securities and Exchange Commission (SEC) is included in this
Joint Proxy Statement/Prospectus.

     Directors who are not employees of Sylvan receive options to purchase
common stock of the Company under the 1993 Director Stock Option Plan.
Otherwise, directors do not receive compensation for service on the Sylvan Board
or any committee thereof, but are reimbursed for their out-of-pocket expenses in
connection with attending meetings.  Under the 1993 Director Stock Option Plan,
each non-employee director, upon appointment, election, or re-election to the
Sylvan Board, and who continues to serve on the Sylvan Board as of the date of
an annual meeting at which directors are elected or re-elected, is granted an
option to purchase 11,250 shares of Sylvan Common Stock at an exercise price
equal to the fair market value of the stock on the date of the grant.  In 1996,
no options were granted under this plan, and no options are available for grant.
No director shall receive an option to purchase more than 11,250 shares in any
calendar year, and no director shall be granted options to purchase more than
33,750 shares in total under the plan.

     All officers have made timely filings of all change in beneficial ownership
declarations required by the SEC during the year ended December 31, 1996.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION IN COMPENSATION
DECISIONS

     None of the directors serving on the Compensation Committee are employees
of Sylvan, and neither the Chief Executive Officer nor any of the named
Executive Officers have served on the Compensation Committee.  No

       Compensation Committee Report.


          Introduction.  The Compensation Committee consists of three outside
directors, none of whom has ever been an officer or employee of the Company.
The function of the Compensation Committee is to recommend to the Board of
Directors policies regarding the Company's compensation of, and to recommend
specific compensation for, the Company's executive officers.  The Compensation
Committee's responsibilities also include administering the Company's stock
option plans and making decisions regarding option grants to officers and other
key employees.  The Committee also periodically reviews the Company's employee
benefit plans that are intended to qualify under Section 401 of the Internal
Revenue Code to determine whether any changes to those plans may be appropriate.
The Compensation Committee meets at least once a year to review management
performance and compensation and to recommend to the Board bonuses and option
grants for current personnel. The Compensation Committee also meets on an as-
needed basis to recommend compensation for newly created or expanded executive
positions.

          In February 1996, the Committee engaged an independent management
consulting firm to review the compensation of the Company's Co-CEOs and to
advise the Committee as to the appropriate level of base salary, short term and
long term incentive compensation, based on comparable public companies' plans
and the consultants' experience in assisting public companies to establish
management compensation plans.

          Compensation Philosophy and Approach.  The principal elements of the
Company's Executive Compensation Program consist of both annual and long-term
compensation, including base salary and annual incentive cash bonuses and, at
appropriate times, long-term incentive compensation in the form of stock
options.  The Committee has put primary emphasis on long-term incentive stock
options based upon their belief that the Co-CEOs should have a significant
portion of their compensation contingent upon increases in the market price of
the Company's Common Stock.  Aided by the review by the management consulting
firm, the Compensation Committee continues to believe that this approach and
philosophy is appropriate.

                                      -86-
<PAGE>
 
          Base Salaries.  The Company's executive officer base salary levels are
submitted for approval by the Board based on the Compensation Committee
recommendations.  In establishing compensation for the Company's executive
officers, the Compensation Committee utilized recommendations of the management
consulting firm.  Based on the management consulting firm's analysis of
executive compensation the salaries of the Co-CEOs was $250,000 in 1996.

          Annual Incentive Cash Bonus.  In addition to base salaries, executive
officers of the Company are eligible to receive annual cash bonuses, at the
discretion of the Board of Directors.  Cash bonuses are determined on the basis
of (a) the overall financial performance of the Company, and (b) annual personal
performance objectives for each officer, established by the Compensation
Committee at the beginning of the year.

          Long-term Incentive Stock Options.  Options are granted to executive
officers and other key employees whom the Compensation Committee determines to
be essential to the future growth and profitability of the Company.  Based upon
performance criteria similar to those applicable to the cash bonus payment, the
Compensation Committee determines the employees to whom options will be granted,
the number of shares covered by each grant, the exercise price and vesting
period for each grant.  The Compensation Committee typically grants stock
options with relatively long vesting periods, creating strong incentives for
recipients of stock option grants to remain in the employ of the Company.

          Messrs. Hoehn-Saric and Becker, the Co-Chief Executive Officers and
Mr. McGee, the Chief Financial Officer, have been entitled to annual stock
option grants under the Company's 1993 Management Stock Option Plan based on the
Company's performance as compared to profitability targets established by the
Compensation Committee and received grants in 1996 from the shareholder approved
1996 Senior Management Plan.  No additional options have been granted from this
plan to date.  

          Equity Position in Caliber Learning Network, Inc.  In July of 1996 the
Board of Directors approved the formation of an entity to pursue an opportunity
identified by Senior Management for establishing an international distribution
network of adult professional education services.  The Board considered many
options for how to best structure the entity needed to pursue this opportunity.
Aided by the review of the independent management consulting firm of the Co-
CEOs' compensation it was concluded that the Co-CEOs receive an equity ownership
of 35% (17.5% each) of the entity as part of their overall compensation package.
Subsequently, the Board and Co-CEOs concluded that securing a strategic partner
for pursuing this opportunity was critical.  In October 1996, Caliber Learning
Network, Inc. was established with MCI as the strategic partner and investor.
The Co-CEOs' equity ownership was diluted based on MCI's investment to 28% (14%
each) in October 1996.  Messrs. Becker and Hoehn-Saric receive no additional
compensation as members of Caliber's board or for their executive position in
Caliber.

          CEO's and President's Compensation.  Mr. Hoehn-Saric has served as
Chief Executive Officer and Chairman of the Board since April 1993, and served
as President from 1988 to 1993.  Mr. Becker has served as President of the
Company since April 1993, and served as CEO of the Sylvan Learning Center
division of the Company from February 1991 to April 1993.  In December 1995, Mr.
Becker was named Co-Chief Executive Officer of the Company and continues to
serve as President of the Company.

          Messrs. Becker and Hoehn-Saric executed employment agreements in 1996
with initial terms ending December 31, 1998.

          Messrs. Hoehn-Saric and Becker, the Co-Chief Executive Officers, may
earn incentive cash bonuses based on the Company's actual annual financial
performance as compared to the annual operating budget and the accomplishment of
specific objectives established at the beginning of the year by the Compensation
Committee.  Financial performance accounts for 80% of the potential bonus and
the remaining 20% is based on the 

                                      -87-
<PAGE>
 
subjective determination by the Committee as to accomplishment of the specific
objectives. A financial performance bonus may be paid if at least 80% of the
financial performance objectives are achieved but is reduced from the target
bonus amount by a formula based on the percentage of the financial performance
objectives that are actually achieved. A bonus of up to 150% of the target bonus
amount can be earned if actual financial performance results were 200% of the
objectives.

          In April 1997, the Compensation Committee recommended, and the Board
of Directors approved, cash bonuses for Messrs. Hoehn-Saric and Becker of
$112,500 each. These bonuses were based on financial performance and
accomplishment of specific objectives in 1996 as described above.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     Ms. Nancy Cole, director, is the President of Educational Testing Service
and serves on its Board of Trustees. Educational Testing Service owns 425,810
shares of stock in Sylvan Learning Systems, Inc. In the ordinary course of its
business, the Company entered into both a domestic and international contract
with Educational Testing Service for the delivery of testing domestically and
delivery and development of a testing network internationally. The Company
generated $19.6 million, $17.3 million and $10.3 million revenues in calendar
year 1996, 1995, and 1994 respectively, from these ETS contracts.

     In July of 1996 the Board of Directors approved the formation of an entity
to pursue an opportunity identified by Senior Management for establishing an
international distribution network of adult professional education services. The
Board considered many options for how to best structure the entity needed to
pursue this opportunity. Aided by the review of the independent management
consulting firm of the Co-CEOs' compensation it was concluded that the Co-CEOs
receive an equity ownership of 35% (17.5% each) of the entity as part of their
overall compensation package. Subsequently, the Board and Co-CEOs concluded that
securing a strategic partner for pursuing this opportunity was critical. In

     AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") dated as of March
12, 1997, by and among Sylvan Learning Systems, Inc., a Maryland corporation
(the "Purchaser") and National Education Corporation, a Delaware corporation
(the "Company").

                              - - - - - - - - - - 

     The Purchaser and the Company have reached an agreement to combine their
companies through a merger (the "Merger") of a wholly-owned Maryland subsidiary,
to be formed of the Purchaser ("Newco") with and into the Company in a
transaction qualifying as a pooling of interests under applicable accounting
rules and a tax-free reorganization under Sections 368(a) of the Internal
Revenue Code of 1986, as amended.  As a result of the Merger, each outstanding
share of the Company's Common Stock shall be converted into 0.58 shares of the
Purchaser's Common Stock (the "Exchange Ratio").  The Purchaser and the Company
wish to enter into a definitive agreement setting forth the terms and conditions
of the Merger.

     Accordingly, in consideration of the foregoing and of the covenants,
agreements, representations and warranties hereinafter contained, the Purchaser
and the Company hereby agree as follows:

     1.  REPRESENTATIONS AND WARRANTIES OF THE PURCHASER.  The Purchaser hereby

represents and warrants to the Company that the statements contained in this
Article I are true and correct, except as set forth in the disclosure schedule
delivered by the Purchaser to the Company on or before the date of this
Agreement (the "Purchaser Disclosure Schedule").  The Purchaser Disclosure

good standing under the laws of the jurisdiction of its incorporation and has
all requisite corporate power and authority to own, lease and operate its
properties and to carry on its businesses as now being conducted, except where
the failure to be so organized, existing and in good standing or to have such

individually or in the aggregate, have a material adverse effect on the
business, assets (whether tangible or intangible), financial condition, results
of operations or business prospects ("Material Adverse Effect") of Sylvan.  The
Purchaser has heretofore delivered to the Company accurate and complete copies
of the Purchaser's Certificate of Incorporation and By-Laws, as currently in

in good standing would not, individually or in aggregate, have a Material
Adverse Effect on Sylvan.

law or any federal, state or local tax liabilities due or to become due whether

         1.15.  Contracts.
                --------- 

                (a) Neither the Purchaser nor any of the Purchaser Subsidiaries
is a party to or subject to: (i) any employment contract with any officer,
consultant, director or employee; (ii) any plan or contract or arrangement
providing for bonuses, pensions, options, deferred compensation, retirement
payments, profit sharing, or the like; (iii) any contract or agreement with any
labor union; (iv) any contract, agreement, instrument or other document that
would be required to be filed as an exhibit to a Registration Statement on Form
S-1 were the Purchaser or any of the Purchaser Subsidiaries to file such a
Registration Statement on the date of this Agreement, (v) any contract,
agreement, instrument or other document not entered into by the Purchaser or any

the Purchaser or any of the Purchaser Subsidiaries is required to make annual
payments to any third party in excess of $500,000 or (vi) any agreement, voting
trust, understanding or arrangement, written or oral, concerning the election of
directors. Neither the Purchaser nor any of the Purchaser Subsidiaries has
breached, or received in writing any claim or threat that it has breached, any
of the terms or conditions of any agreement, contract or commitment referred to
in the prior sentence ("Purchaser Material Contracts") in such a manner as would
permit any other party to cancel or terminate the same or would permit any other
party to seek material damages from the Purchaser or any of the Purchaser
Subsidiaries under any Purchaser Material Contract. Each Purchaser Material
Contract that has not expired or been terminated is in full force and effect and
is not subject to any material default thereunder of which the Purchaser is
aware by any party obligated to the Purchaser or any of the Purchaser
Subsidiaries pursuant to the Purchaser Material Contract.

                (b) The consummation of the Merger and the transactions
contemplated by this Agreement will not cause a default under, or provide any
right of termination or modification with respect to, any Purchaser Material
Contract which default, termination or modification would have a Material
Adverse Effect on Sylvan.

         1.16.  Customers and Suppliers.  Neither the Purchaser nor any of the
                -----------------------                                       
Purchaser Subsidiaries has received notice that, nor do any of them have
knowledge or any reason to believe that, any customer that represented 5% or
more of Purchaser's consolidated revenues in any of the past three years will
not continue to do business with the Purchaser or the Purchaser Subsidiaries at
volumes consistent with past practices subsequent to the Merger.  Neither the
Purchaser nor any of the Purchaser Subsidiaries has any outstanding purchase
contracts or commitments or unaccepted purchase orders which are in excess of
the normal, ordinary and usual requirements of its business.  No entity which is
now supplying, or during 1996 supplied, to the Purchaser or the Purchaser
Subsidiaries products and services has reduced or otherwise discontinued, or
threatened to reduced or discontinue, supplying such items to the Purchaser or
the Purchaser Subsidiaries on reasonable terms, except for such reductions or
discontinuations which would not have a Material Adverse Effect on Sylvan.

         1.17.  Tax Matters.
                ----------- 

                (a) For the purposes of this Agreement, a "Tax" or,
collectively, "Taxes," means any and all material federal, state, local and
foreign taxes, assessments and other governmental charges, duties, impositions
and liabilities, including taxes based upon or measured by gross receipts,
income, profits, sales, use and occupation, and value added, ad valorem,
transfer, franchise, withholding, payroll, recapture, employment, excise and
property taxes, together with all interest, penalties and additions imposed with
respect to such amounts and any obligations under any agreements or arrangements
with any other person or entity with respect to such amounts and including any
liability for taxes of a predecessor entity.

                (b) The Purchaser and the Purchaser Subsidiaries have accurately
prepared and timely filed all material federal, state, local and foreign
returns, estimates, information statements and reports required to be filed at
or before the Effective Time ("Returns") relating to any and all Taxes
concerning or attributable to the Purchaser, any of the Purchaser Subsidiaries
or any of their operations or assets, and such Returns are true and correct in
all material respects and have been completed in all material respects in
accordance with applicable law; and copies of all Returns of the Purchaser and
the Purchaser Subsidiaries for the past three years have been or will be
provided by the Purchaser to the Company.

                (c) The Purchaser and each of the Purchaser Subsidiaries as of
the Effective Time: (i) will have paid all Taxes any of them is required to pay
prior to the Effective Time, (ii) will have withheld with respect to their
employees all federal and state income taxes, FICA, FUTA and other Taxes
required to be withheld, and (iii) will have collected all sales and use taxes
on account of sales by the Purchaser or any Purchaser Subsidiary or the use of
any of their products, except in each instance where any failure to make such
payment or withholding would not be reasonably likely to have a Material Adverse
Effect on Sylvan.

                (d) There is no Tax deficiency outstanding, proposed or assessed
against the Purchaser or any of the Purchaser Subsidiaries that is not reflected
as a liability on the Purchaser Financial Statements nor has the Purchaser or
any of the Purchaser Subsidiaries executed any waiver of any statute of
limitations on or extending the period for the assessment or collection of any
Tax.

         1.18.  Title to Properties; Absence of Liens and Encumbrances, Etc. The
                ------------------------------------------------------------
Purchaser Disclosure Schedule includes a true and complete list of all real
property owned by the Purchaser or the Purchaser Subsidiaries and real property
leased by the Purchaser or the Purchaser Subsidiaries pursuant to leases
providing for the occupancy, in each case, of not less than 20,000 square feet
("Material Leases") and the name of the lessor, the date of the Material Lease
and each amendment to the Material Lease and the aggregate annual rental or
other fee payable under any such Material Lease. The Purchaser and the Purchaser
Subsidiaries have good and marketable title to all their owned properties and
assets, real and personal, in each case free and clear of all liens,
encumbrances and imperfections of title, except those liens, encumbrances or
imperfections of title which individually or in the aggregate would not have a
Material

                                      -10-
<PAGE>
 
Adverse Effect on Sylvan. Neither the Purchaser nor any of the Purchaser
Subsidiaries has received any notice of violation of any applicable zoning laws,
orders, regulations, or requirements relating to its operations or properties it
owns or leases which has not been complied with, nor any proposed changes in any
such laws, orders or regulations which might have a Material Adverse Effect on
Sylvan. The Purchaser has no knowledge of any threatened or impending
condemnation by any Government Entity of any properties owned or leased by the
Purchaser or the Purchaser Subsidiaries. All Material Leases are in good
standing, valid and effective in accordance with their respective terms, and
neither the Purchaser nor any Purchaser Subsidiary is in default under any of
such leases, except where the lack of such good standing, validity and
effectiveness or the existence of such default would not have a Material Adverse
Effect on Sylvan.

         1.19.  Pension and Employee Benefit Plans.
                ---------------------------------- 
 
                (a) The Purchaser has set forth on the Purchaser Disclosure
Schedule all employee benefit plans (as defined in Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA")) and all bonus,
stock option, stock purchase, incentive, deferred compensation, supplemental
retirement, severance and other similar employee benefit plans, and all
unexpired severance agreements, written or otherwise, for the benefit of, or
relating to, any current or former employee of the Purchaser or any of the
Purchaser Subsidiaries or any trade or business (whether or not incorporated)
which is a member or which is under common control with the Purchaser within the
meaning of Section 414 of the Code (an "ERISA Affiliate") (together, the
"Purchaser Employee Plans").

                (b) With respect to each Purchaser Employee Plan, the Purchaser
has made or will make available to the Company, a true and correct copy of (i)
the most recent annual report (Form 5500) filed with the Internal Revenue
Service ("IRS"), (ii) such Purchaser Employee Plan, (iii) each trust agreement
and group annuity contract, if any, relating to such Purchaser Employee Plan and
(iv) the most recent actuarial report or valuation relating to a Purchaser
Employee Plan subject to Title IV of ERISA.

                (c) With respect to the Purchaser Employee Plans, individually
and in the aggregate, no event has occurred, and to the knowledge of the
Purchaser there exists no condition or set of circumstances, in connection with
which the Purchaser could be subject to any liability under ERISA, the Code or
any other applicable law that is reasonably likely to have a Material Adverse
Effect on Sylvan.

                (d) With respect to the Purchaser Employee Plans, individually
and in the aggregate, there are no funded benefit obligations for which
contributions have not been made or properly accrued and there are no unfunded
benefit obligations which have not been accounted for by reserves, or otherwise
properly footnoted in accordance with generally accepted accounting principles,
on the Purchaser Financial Statements, which obligations are reasonably expected
to have a Material Adverse Effect on Sylvan.

                                      -11-
<PAGE>
 
                (e) Except as provided for in this Agreement, neither the
Purchaser nor any of the Purchaser Subsidiaries is a party to any oral or
written (i) union or collective bargaining agreement, (ii) agreement with any
officer or other key employee of the Purchaser or any of the Purchaser
Subsidiaries, the benefits of which are contingent, or the terms of which are
materially altered, upon the occurrence of a transaction involving the Purchaser
of the nature contemplated by this Agreement, (iii) agreement with any officer
providing any term of employment or compensation guarantee extending for a
period longer than one year from the date hereof, providing for the payment of
compensation in excess of $100,000 per annum or providing for severance benefits
or other benefits upon or following termination of employment, or (iv) agreement
or plan, including any stock option plan, stock appreciation right plan,
restricted stock plan or stock purchase plan, any of the benefits of which will
be increased, or the vesting of the benefits of which will be accelerated, by
the occurrence of any of the transactions contemplated by this Agreement or the
value of any of the benefits of which will be calculated on the basis of any of
the transactions contemplated by this Agreement.

                (f) Each of the Purchaser Employee Plans which is intended to
qualify under Section 401 of the Code is designated on the Purchaser Disclosure
Schedule as being a qualified plan (the Plans so designated being hereinafter
referred to as the "Purchaser Qualified Plans"). Each Purchaser Qualified Plan
is qualified under Section 401(a) of the Code and is the subject of a currently
effective determination letter from the Internal Revenue Service confirming such
qualification. True and correct copies of all determination letters from the
Internal Revenue Service with respect to the Purchaser Qualified Plans which
were issued after the effective date of ERISA have been or will be delivered to
the Purchaser. With respect to each Purchaser Qualified Plan, the Purchaser has
not obtained a waiver of any minimum funding requirements imposed by ERISA or
the Code in respect of such Purchaser Qualified Plan, and has not incurred any
liability to the Pension Benefit Guaranty Corporation in connection with any
such Purchaser Qualified Plan. As of the date hereof, the value of the assets in
each of the Purchaser Qualified Plans which is a defined benefit plan exceeds
the present value of accrued benefits of all participants in such Plan when such
benefits are valued on a termination basis using Pension Benefit Guaranty
Corporation interest and other assumptions. No "reportable event," as such term
is defined in ERISA and in regulations issued thereunder, has occurred with
respect to any of the Purchaser Qualified Plans since the effective date of
ERISA.

               (g) The Purchaser has identified to the Company which, if any, of
the Purchaser Employee Plans are multi-employer pension plans (as defined by
ERISA) and the number of employees of Sylvan who participated in multi-employer
plans during the year ended December 31, 1996. Since April 29, 1980, neither the
Purchaser nor any of the Purchaser Subsidiaries has, with respect to any multi-
employer plan, suffered or otherwise caused a "complete withdrawal" or "partial
withdrawal" (as such terms are defined by ERISA).

         1.20.  Foreign Corrupt Practices Act. Neither the Purchaser nor any of
                -----------------------------                                
the Purchaser Subsidiaries, nor any director, officer, agent, employee,
consultant, or any other person associated with or acting on behalf of any of
them, has engaged or is engaged in any course of conduct, or is a party to any
agreement or involved in any transaction, which has or would give 

                                      -12-
<PAGE>
 
rise to a violation of the Foreign Corrupt Practices Act of 1977 or any other
United States statute or regulation governing the conduct of business abroad by
United States corporations and their subsidiaries.

         1.21.  Insurance. The Purchaser Disclosure Schedule lists the insurance
                ---------                                                    
currently carried by the Purchaser and the Purchaser Subsidiaries in respect of
their respective properties and operations, including, without limitation,
information as to limits of coverage, deductibles, annual premium requirements
and expiration dates with respect to product liability, general liability,
umbrella liability, contractual liability, employers' liability, automobile
liability, workers' compensation, property and casualty, business interruption
and other insurance carried by the Purchaser and the Purchaser Subsidiaries
(collectively, the "Purchaser Insurance"). All Purchaser Insurance continues to
be in full force and effect, and the Purchaser and the Purchaser Subsidiaries
are in compliance with all requirements and provisions thereof. None of the
Purchaser Insurance is subject to any retroactive rate or audit adjustments or
co-insurance arrangements. The Purchaser has no reason to believe that any such
Purchaser Insurance will not be renewed upon the expiration thereof at premiums
substantially equivalent to those currently being paid by the Purchaser and the
Purchaser Subsidiaries. The Purchaser Insurance heretofore and currently carried
by the Purchaser and the Purchaser Subsidiaries were and are consistent with
types and amounts of coverages customarily carried by similarly situated
companies.

         1.22.  No Pending Transactions. Except for the transactions
                -----------------------                                     
contemplated by this Agreement and the Other Acquisitions (as hereinafter
defined in Section 3.3), neither the Purchaser nor any of the Purchaser
Subsidiaries is a party to or bound by or the subject of any agreement,
undertaking, commitment or discussion with another party with respect to any
Acquisition Transaction (as hereinafter defined in Section 3.2).

         1.23.  Disclosure. No representation or warranty made by the Purchaser
                ----------                                                     
in this Agreement and no statement contained in a certificate, schedule, list or
other instrument or document specified in or delivered pursuant to this
Agreement, whether heretofore furnished to the Purchaser or hereafter required
to be furnished to the Purchaser, contains or will contain any untrue statement
of a material fact or omits or will omit to state any material fact necessary to
make the statements contained herein or therein not misleading.

         1.24.  Transactions with Affiliates. Neither the Purchaser nor any of
                ----------------------------                             
the Purchaser Subsidiaries is a party to any transaction with any (i) current or
former officer or director of the Purchaser or any of the Purchaser
Subsidiaries, or (ii) any parent, spouse, child, brother, sister or other family
relation of any such officer or director or (iii) any corporation, partnership
or other entity of which any such officer or director or any such family
relation is an officer, director, partner or greater than 10% stockholder (based
on percentage ownership of voting stock) or (iv) any "affiliate" or "associate"
of any such persons or entities (as such terms are defined in the rules and
regulations promulgated under the Securities Act), including, without
limitation, any transaction involving a contract, agreement or other arrangement
providing for the employment of, furnishing of materials, products or services
by, rental of real or personal property from, or otherwise requiring payments
to, any such person or entity.

         1.25.  Pooling of Interests.  To the best of its knowledge, neither the
                --------------------                                            
Purchaser, any of the Purchaser Subsidiaries nor any affiliate of Sylvan has,
through the date of this Agreement, taken or agreed to take any action which
would prevent the Purchaser from accounting for the business combination to be
effected by the Merger as a pooling of interests.

         1.26.  Opinion of Financial Advisor.  The financial advisor to the
                ----------------------------                               
Purchaser, Alex. Brown & Sons Incorporated, has delivered to the Purchaser an
opinion dated the date of this Agreement to the effect that the Exchange Ratio
is fair, from a financial point of view, to Purchaser.

     2.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company hereby
represents and warrants to the Purchaser that the statements contained in this
Article II are true and correct, except as set forth in the disclosure schedule
delivered by the Company to the Purchaser on or before the date of this
Agreement (the "Company Disclosure Schedule").  The Company Disclosure Schedule
shall be arranged in sections corresponding to the numbered and lettered
sections contained in this Article II.  The disclosure in any paragraph shall be
deemed to constitute disclosure for all sections in this Article II.

collectively the "Corporation") is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation and has all requisite corporate power and authority to own, lease
and operate its properties and to carry on its businesses as now being
conducted, except where the failure to be so organized, existing and in good
standing or to have such power and authority would not, and reasonably could not
be expected to, individually or in the aggregate, have a Material Adverse Effect
on the Corporation. The Company has heretofore delivered to the Purchaser
accurate and complete copies of the Company's Certificate of Incorporation and
By-Laws, as currently in effect, and promptly will deliver to the Purchaser
accurate and complete copies of the Articles or Certificate of Incorporation and
By-Laws, as currently in effect, of each of the Company Subsidiaries. The
Company's Disclosure Schedule includes a list of each of the Company
Subsidiaries.

               (b) Each of the Company and the Company Subsidiaries is duly
qualified or licensed and in good standing to do business in each jurisdiction
in which the property owned, leased or operated by it or the nature of the
business conducted by it makes such qualification or licensing necessary, except
in such jurisdictions where the failure to be so duly qualified or licensed and
in good standing would not, individually or in aggregate, have a Material
Adverse Effect on the Corporation.

case of any unaudited financial statements to normal recurring year-end audit
adjustments, which are not expected to be material in amount). Since January 1,
1996, the Company has not made any material changes in the accounting policies
applied to the Company Audited Financial Statements, and no such changes are
currently contemplated nor, to the best of the Company's knowledge, required
under generally accepted accounting principles or the Commission's Regulation 
S-X. The restructuring charges and losses from discontinued operations shown on
the Company Financial Statements have been properly recorded in accordance with
generally accepted accounting principles, represent management's best estimate
of the cost of discontinuing the operations to which such charges relate, and,
to the best of the Company's knowledge, there will be no further charges other
than those already accrued on the Company Financial Statements as a result of
the discontinuation of such operations.

               (b) The Company has heretofore delivered to the Purchaser copies
of: (i) the financial statements of Steck-Vaughn Publishing Corporation ("Steck-
Vaughn") as of and for the years ended December 31, 1993, 1994 and 1995, which
have been audited by Price Waterhouse, independent public accountants (the
"Steck-Vaughn Audited Financial Statements"), and (ii) Steck-Vaughn's unaudited
consolidated financial statements as of and for the twelve months ended December
31, 1996, (the "Steck-Vaughn Unaudited Financial Statements"). The Steck-Vaughn
Audited Financial Statements and Steck-Vaughn Unaudited Financial Statements
(collectively, the "Steck-Vaughn Financial Statements") fairly present, in
conformity with generally accepted accounting principles applied on a consistent
basis by the Company (except as may be indicated in the notes thereto), the
consolidated financial position of Steck-Vaughn and its consolidated
subsidiaries as of the dates thereof and their consolidated results of
operations and cash flows for the periods then ended (subject in the case of any

                                      -16-
<PAGE>
 
unaudited interim financial statements to normal recurring year-end audit
adjustments, which are not expected to be material in amount).

               (c) The Company has heretofore delivered to the Purchaser
complete copies of all periodic reports, statements and other documents
(including Exhibits thereto) that the Company and Steck-Vaughn have filed with
the Commission under the Exchange Act since January 1, 1992 (collectively, the
"Company SEC Reports"). All Company SEC Reports required to be filed with the
Commission by the Company and Steck-Vaughn during the twelve months preceding
the date of this Agreement were filed in a timely manner and complied in all
material respects with the applicable requirements of the Exchange Act and the
rules and regulations promulgated thereunder. At the time filed with the SEC, no
Company SEC Report contained any untrue statement of a material fact or omitted
to state any material fact required to be stated therein or necessary in order
to make the statements therein, in light of the circumstances under which they
were made, not misleading.

         2.4.  No Undisclosed Liabilities.

liabilities or obligations (whether accrued, absolute or contingent), of the
character which, under generally accepted accounting principles, should be
accrued, shown, disclosed or indicated in a consolidated balance sheet of the
Company or explanatory notes or information supplementary thereto, including
without limitation, any liabilities resulting from failure to comply with any
law or any federal, state or local tax liabilities due or to become due whether
(a) incurred in respect of or measured by income for any period ending on or
prior to the close of business on such dates, or (b) arising out of transactions
entered into, or any state of facts existing, on or prior thereto.

               (b) Except as and to the extent reflected or reserved against in

liabilities or obligations (whether accrued, absolute or contingent), of the
character which, under generally accepted accounting principles, should be
accrued, shown, disclosed or indicated in a consolidated balance sheet of Steck-
Vaughn or explanatory notes or information supplementary thereto, including
without limitation, any liabilities resulting from failure to comply with any
law or any federal, state or local tax liabilities due or to become due whether
(a) incurred in respect of or measured by income for any period prior to the
close of business on such dates, or (b) arising out of transactions entered
into, or any state of facts existing, prior thereto.

Material Adverse Effect on the Company, and (iii) the Company and the Company
Subsidiaries have conducted their businesses only in the ordinary course and in
a manner consistent with prior practice.

         2.6.  No Default. Neither the Company nor any of the Company
               ----------

order, writ, injunction, decree, law, statute, rule or regulation applicable to
the Company, any of the Company Subsidiaries or any of their respective

of the transactions contemplated by this Agreement, and (ii) neither the Company

injunction or decree which, insofar as can be reasonably foreseen, individually
or in the aggregate, in the future could have a Material Adverse Effect on the

contemplated hereby. Except as noted on the Company Disclosure Schedule, all
claims listed thereon are covered by the Company's liability insurance (subject
to applicable deductibles not in excess of $500,000) and are being defended by
and at the cost of the Company's liability insurance carrier.

trademarks, service marks and copyrights held by the Company or any of the
Company Subsidiaries are valid and subsisting. Neither the Company nor any of

or other proprietary right of any third party; and (ii) has any knowledge that

owned or leased by the Company or the Company Subsidiaries. All Material Leases
are in good standing, valid and effective in accordance with their respective
terms, and neither the Company nor any Company Subsidiary is in default under
any of such leases, except where the lack of such good standing, validity and
effectiveness or the existence of such default would not have a Material Adverse
Effect on the Corporation.

and in the aggregate, no event has occurred, and to the knowledge of the Company
there exists no condition or set of circumstances, in connection with which the

and in the aggregate, there are no funded benefit obligations for which
contributions have not been made or properly accrued and there are no unfunded

                  (e)   Except as provided for in this Agreement, neither the
Company nor any of the Company Subsidiaries is a party to any oral or written
(i) union or collective bargaining agreement, (ii) agreement with any officer or
other key employee of the Company or any of the Company Subsidiaries, the
benefits of which are contingent, or the terms of which are materially altered,
upon the occurrence of a transaction involving the Company of the nature
contemplated by this Agreement, (iii) agreement with any officer providing any
term of employment or compensation guarantee extending for a period longer than
one year from the date hereof, providing for the payment of compensation in
excess of $100,000 per annum or providing for severance benefits or other
benefits upon or following termination of employment, or (iv) agreement or plan,
including any stock option plan, stock appreciation right plan, restricted stock
plan or stock purchase plan, any of the benefits of which will be increased, or
the vesting of the benefits of which will be accelerated, by the occurrence of
any of the transactions contemplated by this Agreement or the value of any of
the benefits of which will be calculated on the basis of any of the transactions
contemplated by this Agreement.

                  (f)   Each of the Company Employee Plans which is intended to
qualify under Section 401 of the Code is designated on the Company Disclosure
Schedule as being a qualified plan (the Plans so designated being hereinafter
referred to as the "Company Qualified Plans"). Each Company Qualified Plan is
qualified under Section 401(a) of the Code and is the subject of a currently
effective determination letter from the Internal Revenue Service confirming such
qualification. True and correct copies of all determination letters from the
Internal Revenue Service with respect to the Company Qualified Plans which were
issued after the effective date of ERISA have been or will be delivered to the
Purchaser. With respect to each Company Qualified Plan, the Company has not
obtained a waiver of any minimum funding requirements imposed by ERISA or the
Code in respect of such Company Qualified Plan, and has not incurred any
liability to the Pension Benefit Guaranty Corporation in connection with any
such Company Qualified Plan. As of the date hereof, the value of the assets in
each of the Company Qualified Plans which is a defined benefit plan exceeds the
present value of accrued benefits of all participants in such Plan when such
benefits are valued on a termination basis using Pension Benefit Guaranty
Corporation interest and other assumptions. No "reportable event," as such term
is defined in ERISA and in regulations issued thereunder, has occurred with
respect to any of the Company Qualified Plans since the effective date of ERISA.

                  (g)   The Company has identified to the Purchaser which, if
any, of the Company Employee Plans are multi-employer pension plans (as defined
by ERISA) and the number of employees of the Corporation who participated in
multi-employer plans during the year ended December 31, 1996. Since April 29,
1980, neither the Company nor any of the Company Subsidiaries has, with respect
to any multi-employer plan, suffered or otherwise caused a "complete withdrawal"
or "partial withdrawal" (as such terms are defined by ERISA).

           2.20.  Foreign Corrupt Practices Act.  Neither the Company nor any 
                  ----------------------------- 
of the Company Subsidiaries, nor any director, officer, agent, employee,
consultant, or any other person associated with or acting on behalf of any of
them, has engaged or is engaged in any course of conduct, or is a party to any
agreement or involved in any transaction, which has or would give rise to a
violation of the Foreign Corrupt Practices Act of 1977 or any other United
States statute or regulation governing the conduct of business abroad by United
States corporations and their subsidiaries.

           2.21.  Insurance.  The Company Disclosure Schedule lists the 
                  --------- 
insurance currently carried by the Company and the Company Subsidiaries in
respect of their respective properties and operations, including, without
limitation, information as to limits of coverage, deductibles, annual premium
requirements and expiration dates with respect to product liability, general
liability, umbrella liability, contractual liability, employers' liability,
automobile liability, workers' compensation, property and casualty, business
interruption and other insurance carried by the Company and the Company
Subsidiaries (collectively, the "Company Insurance"). All Company Insurance
continues to be in full force and effect, and the Company and the Company
Subsidiaries are in compliance with all requirements and provisions thereof.
None of the Company Insurance is subject to any retroactive rate or audit
adjustments or co-insurance arrangements. The Company has no reason to believe
that any such Company Insurance will not be renewed upon the expiration thereof
at premiums substantially equivalent to those currently being paid by the
Company and the Company Subsidiaries. The Company Insurance heretofore and
currently carried by the Company and the Company Subsidiaries were and are
consistent with types and amounts of coverages customarily carried by similarly
situated companies.

           2.22.  No Pending Transactions.  Except for the transactions 
                  -----------------------
contemplated by this Agreement and the Company Acquisitions (as hereinafter
defined in Section 3.1), neither the Company nor any of the Company Subsidiaries
is a party to or bound by or the subject of any agreement, undertaking,
commitment or discussion with another party with respect to an Acquisition
Transaction (as hereinafter defined in Section 3.2).

           2.23.  Disclosure.  No representation or warranty made by the 
                  ----------
Company in this Agreement and no statement contained in a certificate, schedule,
list or other instrument or document specified in or delivered pursuant to this
Agreement, whether heretofore furnished to the Purchaser or hereafter required
to be furnished to the Purchaser, contains or will contain any untrue statement
of a material fact or omits or will omit to state any material fact necessary to
make the statements contained herein or therein not misleading.

           2.24.  Transactions with Affiliates.  Neither the Company nor any 
                  ----------------------------  
of the Company Subsidiaries is a party to any transaction with any (i) current
or former officer or director of the Company or any of the Company Subsidiaries,
or (ii) any parent, spouse, child, brother, sister or other family relation of
any such officer or director or (iii) any corporation, partnership or other
entity of which any such officer or director or any such family relation is an
officer, director, partner or greater than 10% stockholder (based on percentage
ownership of voting stock) or (iv) any "affiliate" or "associate" of any such
persons or entities (as such terms

                                      -26-
<PAGE>
 
are defined in the rules and regulations promulgated under the Securities Act),
including, without limitation, any transaction involving a contract, agreement
or other arrangement providing for the employment of, furnishing of materials,
products or services by, rental of real or personal property from, or otherwise
requiring payments to, any such person or entity.

           2.25.  Pooling of Interests.  To the best of its knowledge, neither 
                  --------------------
the Company, any of the Company Subsidiaries nor any affiliate of the
Corporation has, through the date of this Agreement, taken or agreed to take any
action which would prevent the Purchaser from accounting for the business
combination to be effected by the Merger as a pooling of interests.

           2.26.  Opinion of Financial Advisor.  The financial advisor to the 
                  ----------------------------
Company, BZW, the investment banking division of Barclays Bank PLC ("BZW"), has
delivered to the Company an opinion dated the date of this Agreement to the
effect that the aggregate Merger consideration to be received by the holders of
the issued and outstanding shares of Company Common Stock is fair in the
aggregate from a financial point of view to the holders of the Company Common
Stock as a group.

           2.27.  Section 203 of the DGCL Not Applicable.  The Boards of 
                  -------------------------------------- 
Directors of the Company and the Company Subsidiaries have taken all action so
that the restrictions contained in Section 203 of the DGCL applicable to a
"business combination" (as defined in Section 203) will not apply to the
execution, delivery or performance of this Agreement or the consummation of the
Merger, the other transactions contemplated by this Agreement or any other
transaction between the Purchaser or any of its subsidiaries and the Company or
any of its subsidiaries.

     SECTION 3.   COVENANTS.

           3.1    Conduct of Business of the Company.  Except as contemplated

aggregate, do not result in a material increase in benefits or compensation
expense to it, and as required under existing agreements or in the ordinary
course of business generally consistent with past practice) increase in any
manner the compensation or fringe benefits of any director, officer or employee

           3.2.   No Solicitation.  The Company, its affiliates and their 
                  --------------- 
respective officers, directors, employees, representatives and agents (i) shall
immediately cease any existing discussions or negotiations, if any, with any
parties with respect to any acquisition (other than the 

                                      -29-
<PAGE>
 
transactions contemplated by this Agreement or the Company Acquisitions) of all
or any material portion of the assets of, or any equity interest in, the Company
or any of the Company Subsidiaries or any business combination with the Company
or any of the Company Subsidiaries, (ii) shall not solicit, initiate, encourage,
or furnish information in response to any inquiries or proposals that
constitute, or could reasonably be expected to lead to, a proposal or offer for
a merger, consolidation, business combination, sale of substantial assets, sale
of shares of capital stock (including without limitation by way of a tender
offer or similar transactions involving the Company, other than the transactions
contemplated by this Agreement) (any of the foregoing transactions being

engage in negotiations or discussions concerning, or provide any non-public
information to any person or entity relating to, any Acquisition Transaction, or
(iv) shall not agree to, approve or recommend any Acquisition Transaction;
except, with respect to clauses (ii) (as to the furnishing of information only)
(iii) and (iv), where the Board of Directors of the Company has received the
written opinion of Irell & Manella LLP to the effect that the failure of the
Board of Directors to so act would constitute a violation of the Board of
Directors' fiduciary responsibilities to the holders of the Company Common Stock
under the DGCL (it being understood that for this purpose, the failure to
respond to an Acquisition Proposal which in the judgment of the Company's Board
of Directors and BZW is superior, from a financial point of view, to the
Company's stockholders may be deemed to be a breach of such fiduciary duty). If
the Company shall nevertheless receive any indications of interests or proposals
with respect to any Acquisition Transactions, it shall provide a copy of any
such written proposal to the Purchaser immediately after receipt thereof by the
Company or any of its representatives or agents.

           3.3.   Conduct of Business of the Purchaser.  Except as contemplated
                  ------------------------------------

having business dealings with it, to the end that its goodwill and ongoing

other person or entity (other than to subsidiaries of the Purchaser or advances
to employees in the ordinary course of business consistent with past practice
and in amounts not material to the maker of such loan or advance); (iv) pledge
or otherwise encumber shares of capital stock of the Purchaser or any of the
Purchaser Subsidiaries; or (v) mortgage or pledge any of its material assets,
tangible or intangible, or create or suffer to exist any material Lien
thereupon;

                  (e)   except as may be required by law or as contemplated by
this Agreement or the Other Acquisitions, enter into, adopt or amend or
terminate any bonus, profit sharing, compensation, severance, termination, stock
option, stock appreciation right, restricted stock, performance unit, stock
equivalent, stock purchase agreement, pension, retirement, deferred

plan, fund or other arrangement for the benefit or welfare of any director,
officer or employee in any manner, or (except for normal increases in the

would make any of the representations or warranties of the Purchaser and
Acquisition contained in this Agreement untrue or incorrect as of the date when
made.

           3.4.   Access to Information.
                  --------------------- 

                  (a)   Between the date hereof and the Effective Time, the
Company and the Purchaser will give each other and their respective authorized
representatives reasonable access to all employees, plants, offices, warehouses
and other facilities and to the other's books and records and those of the
other's subsidiaries, will permit each other to make such inspections as the
requesting party may reasonably request and will cause each other's officers and
those of the other's subsidiaries to furnish the requesting party with such

Agreement, the Purchaser and the Company shall prepare and shall cooperate with
the other in preparing and shall file with the Commission the Joint Proxy

provided that the Purchaser shall not be obligated to agree to account for the
Merger as a "purchase" in order to have the S-4 declared effective by the

this Agreement; (iii) contesting any legal proceeding relating to the Merger;
and (iv) the execution of any additional instruments necessary to consummate the
transactions contemplated hereby.

           3.7.   Public Announcements.  The Purchaser and the Company will 
                  -------------------- 
consult with each other before issuing any press release or otherwise making any
public statements with respect to the Merger or this Agreement, and shall not
issue any such press release or make any such public statement prior to such
consultation, except as may be required by applicable law or pursuant to the
rules of the Commission or the Purchaser's listing agreement with the Nasdaq
Stock Market and the Company's listing agreement with the New York Stock
Exchange, Inc.

           3.8.   Stockholders Meetings.
                  --------------------- 

                  (a)   The Company and the Purchaser each shall call a meeting
of its respective stockholders to be held as promptly as practicable for the
purpose of voting, in the case of the Company, upon this Agreement and the
Merger and, in the case of the Purchaser, upon (i) the issuance of shares of
Purchaser Common Stock pursuant to the Merger, (ii) amendment of the Purchaser's
Charter for the purpose of increasing the number of authorized shares of
Purchaser Common Stock to 90,000,000 and (iii) election of the four nominees
submitted by the Company to the Purchaser prior to the execution of this
Agreement to the Purchaser Board of Directors (collectively, the "Purchaser
Voting Proposal"). The Company and the Purchaser will, through their respective
Boards of Directors, recommend to their respective stockholders approval of such
matters and will coordinate and cooperate with respect to the timing of such
meetings and shall use their best efforts to hold such meetings on the same day
and as soon as practicable after the date hereof. Each party shall use all
reasonable efforts to solicit from its stockholders proxies in favor of such
matters.

                  (b)   The Purchaser shall also propose to its stockholders at
the Purchaser Stockholders' Meeting, as a proposal separate from the Purchaser
Voting Proposal, an increase in the number of shares of the Purchaser Common
Stock reserved for issuance under one or more of the Purchaser's employee stock
option plans by an aggregate of 4,000,000 shares. The approval by the
Purchaser's stockholders of such additional proposal, however, shall not be a
condition to the closing of the Merger under this Agreement.

           3.9.   Tax-Free Reorganization.  The Purchaser and the Company shall
                  ----------------------- 
each use its best efforts to cause the Merger to be treated as a reorganization
within the meaning of Section 368(a) of the Code.

           3.10   Pooling Accounting.  The Purchaser and the Company shall each
                  ------------------
use its best efforts to cause the business combination to be effected by the
Merger to be accounted for as a pooling of interests. Each of the Purchaser and
the Company shall use its best efforts (i) to cause its respective Affiliates
(as defined in Section 3.11 below) not to take any action that would adversely
affect the ability of the Purchaser to account for the business combination to
be effected by the Merger as a pooling of interests and (ii) to cause its
respective Affiliates to sign and deliver to the Purchaser a customary "pooling
letter" in form and substance agreed upon by the Company and the Purchaser.

           3.11.  Affiliate Agreements.  Upon the execution of this Agreement, 
                  --------------------
the Purchaser and the Company will provide each other with a list of those
persons who are, in their respective reasonable judgment, "affiliates" of the
Purchaser or the Company, respectively, within the meaning of Commission Rule
145 (each such person who is such an "affiliate" is referred to as an
"Affiliate"). The Purchaser and the Company shall provide each other such
information and documents as the other shall reasonably request for purposes of
reviewing such list and shall notify the other party in writing regarding any
change in the identity of its Affiliates prior to the Effective Time. The
Company shall use its best efforts to deliver or cause to be delivered to the
Purchaser by April 15, 1997 (and in any case shall deliver to the
Purchaser prior to the Effective Time) from each of the Affiliates of the
Company, an executed Affiliate Agreement, in form and substance satisfactory to
the Purchaser and the Company, by which such Affiliate of the Company agrees to
comply with the applicable requirements of Rule 145 ("Affiliates Agreement").
The Purchaser shall be entitled to place appropriate legends on the certificates
evidencing any of the Purchaser Common Stock to be received by such Affiliates
of the Company pursuant to the terms of this Agreement, and to issue appropriate
stop transfer instructions to the transfer agent for the Purchaser Common Stock,
consistent with the terms of the Affiliates Agreements.

           3.12.  NASDAQ Quotation.  The Purchaser shall file an Application for
                  ----------------                                              
Listing of Additional Shares with the Nasdaq Stock Market (National Market)
prior to the Effective Time and will otherwise use its best efforts to cause the
shares of the Purchaser Common Stock to be issued in the Merger to be approved
for quotation on the Nasdaq Stock Market (National Market), subject to official
notice of issuance.

           3.13   Brokers or Finders.  Each of the Purchaser and the Company
                  ------------------                                        
represents, as to itself, and the Purchaser Subsidiaries and Affiliates of the
Purchaser, in the case of the Purchaser, and the Company Subsidiaries and
Affiliates of the Company, in the case of the Company, that no agent, broker,
investment banker, financial advisor or other firm or person is or will be
entitled to any broker's or finder's fee or any other commission or similar fee
in connection with any of the transactions contemplated by this Agreement,
except BZW, whose fees and expenses will be paid by the Company in accordance
with the Company's agreement 

                                      -35-
<PAGE>
 
with such firm (copies of which have been delivered by the Company to the
Purchaser prior to the date of this Agreement), and Alex. Brown & Sons
Incorporated, whose fees and expenses will be paid by the Purchaser in
accordance with the Purchaser's agreement with such firm (copies of which have
been delivered by the Purchaser to the Company prior to the date of this
Agreement), and each of the Purchaser and the Company agrees to indemnify and
hold the other harmless from and against any and all claims, liabilities or
obligations with respect to any other fees, commissions or expenses asserted by
any person on the basis of any agreement, act or statement alleged to have been
made by such party, its Affiliates and, in the case of the Purchaser, the
Purchaser Subsidiaries, and the Company Subsidiaries, in the case of the
Company.

     3.14  Indemnification.
           --------------- 

           (a) The Company shall and, the Purchaser shall, from and after the
Effective Time, indemnify, defend and hold harmless each person who is now, or
has been at any time prior to the date of this Agreement or who becomes prior to
the Effective Time, an officer or director of the Company or any of the Company
Subsidiaries (the "Indemnified Parties") against all losses, claims, damages,
costs, expenses, liabilities or judgments or amounts that are paid in settlement
with the approval of the indemnifying party (which approval shall not be
unreasonably withheld) of or in connection with any claim, action, suit,
proceeding or investigation based in whole or in part on or arising in whole or
in part out of the fact that such person is or was a director or officer, of the
Company or any of the Company Subsidiaries, whether pertaining to any matter
existing or occurring at or prior to the Effective Time and whether asserted or
claimed prior to, or at or after, the Effective Time ("Indemnified Liabilities")
including, without limitation, all losses, claims, damages, costs, expenses,
liabilities or judgments based in whole or in part on, or arising in whole or in
part out of, or pertaining to this Agreement or the transactions contemplated
hereby, in each case to the full extent a corporation is permitted under the
DGCL or the Maryland General Corporation Law, as the case may be, to indemnify
its own directors and officers.  The Company or the Purchaser, as the case may
be, will pay expenses in advance of the final disposition of any such action or
proceeding to each Indemnified Party to the full extent permitted by law upon
receipt of any undertaking contemplated by Section 145(e) of the DGCL.  Without
limiting the foregoing, in the event any such claim, action, suit, proceeding or
investigation is brought against any Indemnified Party (whether arising before
or after the Effective Time), (i) the Indemnified Parties may retain counsel
satisfactory to them and the Company (or them and the Purchaser after the
Effective Time), (ii) the Company (or, after the Effective Time, the Purchaser)
shall pay all reasonable fees and expenses of such counsel for the Indemnified
Parties promptly as statements therefor are received, and (iii) the Company (or,
after the Effective Time, the Purchaser) will use all reasonable efforts to
assist in the defense of any such matter, provided that neither the Company nor
the Purchaser shall be liable for any settlement of any claim effected without
its written consent, which consent shall not be unreasonably withheld.  Any
Indemnified Party wishing to claim indemnification under this Section 3.14, upon
learning of any such claim, action, suit, proceeding or investigation, shall
promptly notify the Company or the Purchaser (but the failure 

                                      -36-
<PAGE>
 
so to notify an Indemnifying Party shall not relieve it from any liability which
it may have under this Section 3.14 except to the extent such failure prejudices
such party), and shall deliver to the Company (or, after the Effective Time, the
Purchaser) the undertaking contemplated by the DGCL or the Maryland General
Corporation Law, as the case may be. The Indemnified Parties as a group may
retain only one law firm to represent them with respect to each such matter
unless there is, under applicable standards of professional conduct, a conflict
on any significant issue between the positions of any two or more Indemnified
Parties.

          (b) For a period of five years after the Effective Time, the Purchaser
shall use reasonable efforts to maintain in effect, if available, directors' and
officers' liability insurance covering those persons who are currently covered
by the Company's directors' and officers' liability insurance policy (a copy of
which has heretofore been delivered to the Purchaser) on terms and in an amount
comparable to those now applicable to directors and officers of the Company;
provided, however, that in no event shall the Purchaser be required to expend in
any year in excess of 125% of the current premium being paid by the Company for
such coverage.

          (c) In the event that the Purchaser or any of its respective
successors and assigns consolidates with or merges into any other person and
shall not be the continuing or surviving corporation or entity of such
consolidation or merger or transfers and conveys all or substantially all of its
property and assets to any person, then, and in each case, proper provisions
shall be made so that the successors and assigns of the Purchaser assume the
obligations set forth in this Section 3.14.

          (d) The provisions of this Section 3.14 are intended to be for the
benefit of, and shall be enforceable by, each Indemnified Party, his or her
heirs and representatives, and may not be amended, altered or repealed without
the written consent of any affected Indemnified Party.

     3.15.  Voting Agreements.  The Company shall use its best efforts to cause
            -----------------                                                  
each person who is identified as an Affiliate of the Company to execute and
deliver to the Purchaser a Voting Agreement substantially in the form attached
hereto as Exhibit   within ten (10) days from the date that the Joint Proxy
Statement is mailed to the Company's and the Purchaser's stockholders.  The
Purchaser shall use its best efforts to cause each person who is identified as
an Affiliate of the Purchaser to execute and deliver to the Company a Voting
Agreement substantially in the form attached hereto as Exhibit     within ten
(10) days from the date that the Joint Proxy Statement is mailed to the
Company's and the Purchaser's stockholders.

     3.16.  Notification of Certain Matters.  The Company shall give prompt
            -------------------------------                                
notice to the Purchaser, and the Purchaser shall give prompt notice to the
Company, of (i) the occurrence or nonoccurrence of any event, the occurrence or
nonoccurrence of which would be likely to cause any representation or warranty
contained in this Agreement to be untrue or inaccurate in any material respect
at or prior to the Effective Time (as defined below), and (ii) any material
failure of the Company or the Purchaser, as the case may be, to comply with or
satisfy any 

                                      -37-
<PAGE>
 
covenant, condition or agreement to be complied with or satisfied by it
hereunder; provided, however, that the delivery of any notice pursuant to this
Section 3.16 shall not cure such breach or non-compliance or limit or otherwise
affect the remedies available hereunder to the party receiving such notice.

     3.17  Election to the Purchaser Board of Directors.  The Purchaser shall
           --------------------------------------------                      
take such action as is necessary to cause the size of its Board of Directors to
increase to ten (10) persons, six (6) of which shall be:  Douglas L. Becker, R.
Christopher Hoehn-Saric, William Pollock (or his designee), Nasser Kazeminy (or
his designee), Sam Yau and the designee of Educational Testing Services.  Of the
remaining four (4) persons, three (3) will be selected by the Company from the
Company's existing Board of Directors and the final person will be selected by
the Purchaser from the Purchaser's existing Board of Directors.  It is
understood that the Purchaser may decide to eliminate its classified Board of
Directors in connection with the Merger, in which event each director would
serve a one year term.  However, if the Purchaser decides to maintain its
classified Board of Directors, the Company's nominees and Sam Yau shall be
elected to serve for varying terms corresponding to each of the three classes of
directors such that not more than two Company nominees are included in any one
class.

     3.18  Registration Statement on Form S-3.  As soon as practicable after the
           ----------------------------------                                   
end of the thirtieth day following the Effective Date, but in no event later
than 90 days following the Effective Date, the Purchaser shall file with the
Commission a Registration Statement on Form S-3 (the "Form S-3") relating to the
shares of the Purchaser Common Stock issued in respect of those shares of
Company Common Stock issued upon conversion of the Debentures in the fall of
1995 which remain subject to an effective registration statement on Form S-3
filed with the SEC by the Company (the "Debenture Shares").  Further, the
Purchaser shall take all steps reasonably necessary to maintain the
effectiveness of the Form S-3 until such time as the holders of such Debenture
Shares are permitted to sell such Debenture Shares without regard to the volume
restrictions under Rule 144 or Rule 145 under the Securities Act.

     3.19  Amendment to Indenture.  Each of the Purchaser and the Company will
           ----------------------                                             
use its best efforts to cause the Trustee under the Indenture relating to the
Debentures to amend the Indenture, effective at the Effective Time, such that
the Purchaser assumes the rights and obligations of the Company thereunder.

     3.20  Employment, Non-Compete and Continuity Agreements.  The Company will
           -------------------------------------------------                   
use its best efforts to cause each of Jerry Nine, Roy Sunley and James L'Allier
to have entered into employment agreements in form and substance satisfactory to
the Purchaser, which employment agreements shall include non-competition
agreements during and following termination or expiration of such employment
agreements and which shall be replacement agreements to the employment
agreements between said individuals and the Company or a Company Subsidiary.

                                      -38-
<PAGE>
 
     3.21.  Cause Conditions to be Satisfied.  Each of the Purchaser and the
            --------------------------------                                
Company will use its best efforts to cause all of the conditions described in
Section 5 of this Agreement to be satisfied (to the extent such matters
reasonably are within its control).

     3.22.  Publication of Combined Results of Operations.  As soon as
            ---------------------------------------------             
practicable after the end of the thirtieth day following the Effective Date, the
Purchaser shall publish results of operations of the Purchaser, including those
of the Company, for such 30 day period sufficient to permit Affiliates to make
sales of the Purchaser's Common Stock received in the Merger without adversely
affecting the pooling of interests accounting treatment for the Merger.

  4. MERGER OF THE PURCHASER AND NEWCO.  Subject to the terms and conditions
of this Agreement, the Purchaser and the Company agree to effect the following
transactions at the closing:

     4.1.  Conditions.  The Purchaser and the Company will deliver to the other
           ----------                                                          
appropriate evidence of the satisfaction of the conditions to their respective
obligations hereunder.

     4.2.  Merger.  The Merger shall have the effects set forth under the
           ------                                                        
General Corporation Law of Maryland and the DGCL.  Without limiting the
generality of the foregoing and subject thereto, at the Effective Time (the time
immediately after which the Articles of Merger have been accepted for record by
the SDAT and the Certificate of Merger has been accepted for record by the
Delaware Secretary of State), Newco will be merged with and into the Company,
which shall survive the Merger; and all the properties, rights, privileges,
powers and franchises of the Company and Newco shall vest in the Company, as the
surviving corporation in the Merger, and all debts, liabilities and duties of
the Company and Newco shall become the debts, liabilities and duties of the
Company, as the surviving corporation in the Merger.

     4.3.  Conversion of the Shares of Company and Newco Common Stock.  (a)  As
           ----------------------------------------------------------          
a result of the Merger and without any action by the holders thereof, each share
of Company Common Stock issued and outstanding immediately prior to the Merger
(excluding shares held by the Company as treasury stock, if any, which shares
shall be canceled and extinguished), and all rights in respect thereof, shall be
converted into 0.58 shares of Purchaser Common Stock (the "Exchange Ratio").
Each share of Purchaser Common Stock issued pursuant to the Merger shall be
fully paid and non-assessable.  From and after the Effective Time, each
certificate which theretofore represented shares of Company Common Stock shall
evidence ownership of shares of Purchaser Common Stock on the basis hereinabove
set forth, and the conversion shall be complete and effective at the Effective
Time without regard to the date or dates on which outstanding certificates
representing converted shares of Company Common Stock may be surrendered for
exchange for certificates representing shares of Purchaser Common Stock.

          (b) As a result of the Merger and without any action by the holders
thereof, each share of Newco Common Stock issued and outstanding immediately
prior to the 

                                      -39-
<PAGE>
 
Merger, and all rights in respect thereof, shall be converted into one share of 
Common Stock of the Company, as the surviving corporation in the Merger.
 
     4.4.  Fractional Shares.  No fractional shares of Purchaser Common Stock
           -----------------                                                 
will be issued in connection with the Merger.  As a mechanical device for
rounding fractional interests to whole shares, in any case where the conversion
ratio provided for in Section 6.4 indicates that any holder of Company Common
Stock would otherwise be entitled to delivery of a fractional share of Purchaser
Common Stock, such holder shall be entitled to receive a cash payment with
respect to such fraction of a share to which such holder otherwise would be
entitled.  Such cash payment shall be equal to the product obtained by
multiplying the fraction of a share to which the holder thereof otherwise would
be entitled by the average closing price of the Purchaser Common Stock on the
Nasdaq Stock Market (National Market) for the ten (10) trading days immediately
preceding the Effective Time.

     4.5   Exchange of Shares of Company Common Stock.
           ------------------------------------------ 

           (a) Prior to the Effective Time, the Purchaser shall designate a bank
or trust company reasonably acceptable to the Company to act as Exchange Agent
in connection with the Merger (the "Exchange Agent") pursuant to an exchange
agency agreement providing for the matters set forth in this Section 4.5, and
otherwise reasonably satisfactory to the Company.  At or prior to the Effective
Time, the Purchaser shall deposit with the Exchange Agent certificates
representing the shares of the Purchaser Common Stock issuable pursuant to
Section 4.3 in exchange for the shares of Company Common Stock (the "Exchange
Fund").

           (b) Promptly after the Effective Time, the Exchange Agent shall mail
to each record holder, as of the Effective Time, of an outstanding certificate
or certificates which immediately prior to the Effective Time represented shares
of the Company Common Stock (the "Certificates"), a form letter of transmittal
(which shall specify that delivery shall be effected, and risk of loss and title
to the Certificates shall pass, only upon proper delivery of the Certificates to
the Exchange Agent) and instructions for use in effecting the surrender of the
Certificates in exchange for certificates representing shares of the Purchaser
Common Stock.  Upon surrender to the Exchange Agent of a Certificate, together
with a duly executed letter of transmittal and any other required documents, the
holder of such Certificate shall receive in exchange therefor (as promptly as
practicable) a certificate representing that number of whole shares of Purchaser
Common Stock which such holder has the right to receive pursuant to this Section
4, and the Certificate so surrendered shall forthwith be canceled.  If a
transfer of ownership of shares of Company Common Stock which was not previously
registered on the Company's transfer records occurs or is requested, a
certificate representing the appropriate number of shares of Purchaser Common
Stock may be issued to the transferee if the Certificate so surrendered is
properly endorsed or otherwise in proper form for transfer, provided that the
signatures on the Certificate or any related stock power shall be properly
guaranteed and the person requesting such transfer shall pay any transfer or
other taxes required by reason of such transfer.  Until surrendered in
accordance with the provisions of this Section 4.5(b), each Certificate (other
than Certificates representing shares of Company Common Stock held in the

                                      -40-
<PAGE>
 
Company's treasury or by the Purchaser or any subsidiary of the Company or the
Purchaser, shall represent for all purposes only the right to receive for each
share of Company Common Stock represented thereby shares of Purchaser Common
Stock and cash in lieu of fractional shares, all as provided for under this
Agreement.

          (c) After the Effective Time, there shall be no transfers on the stock
transfer books of the Purchaser of the shares of Company Common Stock which were
outstanding immediately prior to the Effective Time.  If, after the Effective
Time, Certificates are presented to the Purchaser, they shall be canceled and
exchanged as provided for, and in accordance with the procedures set forth, in
this Section 4.

          (d) From and after the Effective Time, the holders of Certificates
evidencing ownership of shares of Company Common Stock outstanding immediately
prior to the Effective Time shall cease to have any rights with respect to such
shares of Company Common Stock, except as otherwise provided herein or by
applicable law.  Such holders shall have no rights, after the Effective Time,
with respect to such shares of Company Common Stock except to surrender such
Certificates in exchange for shares of Purchaser Common Stock as provided for
under this Agreement.

          (e) Any portion of the Exchange Fund which remains undistributed to
the stockholders of the Company for one year after the Effective Time shall be
delivered to the Purchaser, upon demand, and any stockholders of the Company who
have not previously complied with this Section 4.5 shall thereafter look only to
the Purchaser for delivery of shares of Purchaser Common Stock, any cash in lieu
of fractional shares of Purchaser Common Stock and any dividends or
distributions with respect to Purchaser Common Stock (without interest thereon).

          (f) Neither the Purchaser nor the Company shall be liable to any
holder of shares of Company Common Stock or Purchaser Common Stock, as the case
may be, for such shares (or dividends or distributions with respect thereto)
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law.

     4.6. Issuance of Shares in Another Name. If any certificate for shares of
          ----------------------------------
Purchaser Common Stock is to be issued in a name other than the exact name in
which the certificate surrendered is exchange therefore is registered, it shall
be a condition of the issuance thereof that the certificate so surrendered shall
be properly endorsed and otherwise in proper form for transfer and that the
person requesting such exchange pay to the Exchange Agent any transfer or other
taxes required by reason thereof or establish to the satisfaction of the
Exchange Agent that such tax has been paid or is not payable.

     4.7. The Company Transfer Books Closed and Stock Delisted. At the
          ----------------------------------------------------
Effective Time, the stock transfer books of the Company shall be deemed closed,
and no transfer of shares of Company Common Stock shall be made thereafter. The
Company shall notify the National Association of Securities Dealers, Inc. and
the New York Stock Exchange, Inc., and

                                      -41-
<PAGE>
 
each transfer agent and registrar for the shares of Company Common Stock, at
least ten (10) days before the Effective Time that no transfer of shares will be
made after that date. In anticipation of the Effective Time, the Company shall
do all such things necessary to cause trading in its shares to be terminated
simultaneously with the Effective Time.

     4.8.  Stock Options. From and after the Effective Time, the Company Options
           -------------
and the option plans related thereto shall be deemed to have been adopted by the
Purchaser and shall continue thereafter as separate stock options and separate
stock option plans of the Company, subject to amendment or termination as
provided therein, and to the following: (i) the then outstanding options to
purchase shares of Company Common Stock under such stock option plans shall
relate, without change in their terms and conditions, to the number of shares of
Purchaser Common Stock into which such Company shares would have been
convertible if the Company Options had been exercised prior to the Effective
Time, rounded to the nearest whole share, (ii) such stock options plans shall
continue in effect only with respect to the Company Options then outstanding,
and no further grants shall be made thereunder, and (iii) the exercise period of
all Company Options that would otherwise terminate earlier shall be extended
until the later of 90 days following satisfaction of the covenant specified in
Section 3.20 or 90 days following registration of Purchaser's Common Stock
underlying the Company Options on the Commission's Form S-8. From and after the
Effective Time, the then outstanding stock options and related stock option
plans of NETG shall continue. Holders of such outstanding NETG options shall
execute individual agreements confirming such continuation of such outstanding
options and plans.

     4.9.  Adjustments. If after the date of this Agreement and prior to the
           -----------
Effective Time the Purchaser shall declare a stock dividend upon, or subdivide,
split up, reclassify or combine the Purchaser Common Stock, and the record date
for such action shall occur prior to the Effective Time, then upon the
effectiveness of the Merger, the number of shares of Purchaser Common Stock to
be delivered for each share of Company Common Stock shall be adjusted so that
each holder of shares of Company Common Stock shall be entitled to receive such
number of shares of Purchaser Common Stock that it would own, or be entitled to
own, if the Effective Time had occurred immediately prior to the occurrence of

vote of the stockholders of the Purchaser in favor of the Purchaser Voting
Proposal shall not have been obtained; or

          (e) by the Purchaser, if (i) the Board of Directors of the Company
shall have withdrawn or modified its recommendation of this Agreement or the
Merger, or shall have resolved to do any of the foregoing, for any reason other
than the occurrence of an event relating to Sylvan which has a Material Adverse
Effect on Sylvan, or (ii) the Company fails to call and hold the Company
Stockholders' Meeting within forty (40) days after the Commission declares the

          (f) by the Company, if (i) the Board of Directors of the Purchaser

than the occurrence of an event relating to the Company which has a Material
Adverse Effect on the Company or (ii) the Purchaser fails to call and hold the
Purchaser Stockholders' Meeting within forty (40) days after the Commission
declares the S-4 effective;

          (g) by the Purchaser or the Company, as the case may be, if there has
been a material breach of any representation, warranty, covenant or agreement on
the part of the other party set forth in this Agreement, which breach shall not
have been cured in the case of a representation or warranty, prior to the
Closing or, in the case of a covenant or agreement, within 20 business days

termination results from the willful breach by a party of any of its
representations, warranties or covenants set forth in this Agreement; provided
that, the provisions of Sections 3.4(b), 3.13 and 6.3 of this Agreement shall
remain in full force and effect and survive any termination of this Agreement.

the requisite vote for approval of this Agreement and the Merger by the
stockholders of the Company at the Company Stockholders' Meeting or (B) pursuant
to Section 6.1(g) after a material breach by the Company of this Agreement;
provided, however, in the event the Company shall have consummated an
Acquisition Transaction in which the Company or substantially all of its assets
are acquired (even if the acquisition is structured so that the Company or one
of its subsidiaries is the survivor in the transaction) by a party other than
the Purchaser or any of its affiliates (in any case, a "Third Party
Acquisition") at any time on or before the expiration of eight calendar months
from the Purchaser's termination under clauses (A) and (B) of this paragraph
6.3(b)(ii), the Company shall, or shall cause its successor to pay the Purchaser
an additional amount of liquidated damages equal to $20,000,000.

          (c) As reimbursement for expenses incurred by the Company relating to
the transactions contemplated by this Agreement prior to termination and as

determine with certainty in the event of such termination), the Purchaser shall
pay the Company a fee equal to $10,000,000 upon the termination of this
Agreement by the Company pursuant to (i) Section 6.1(d) as a result of the
failure to receive the requisite vote for approval of this Agreement and the
Merger by the stockholders of the Purchaser at the Purchaser Stockholders'
Meeting or (ii) pursuant to Section 6.1(g) after a material breach by the
Purchaser of this Agreement.

           (d) The expenses and fees, if applicable, payable pursuant to

first to occur of the events described therein; provided that, in no event shall
the Company (or its successor) or the Purchaser, as applicable, be required to
pay any expenses or termination fees, if applicable, to the other party, if,
immediately prior to the termination of this Agreement, the terminating party
was in breach of any of its material obligations under this Agreement. The
payments provided in this Section 6.3 shall be the exclusive remedy for any
breach of this Agreement.

     6.4.  Amendment.  This Agreement may be amended by action taken by the
           ---------                                                       
Company and the Purchaser at any time before or after Purchaser Stockholder

amended except by an instrument in writing signed on behalf of the parties
hereto.

     6.5.  Extension; Waiver.  At any time prior to the Effective Time, each

waive any inaccuracies in the representations and warranties of the other party
contained herein or in any document, certificate or writing delivered pursuant
hereto, or (iii) waive compliance by the other party with any of the agreements
or conditions contained herein.  Any agreement on the part of either party
hereto to any such extension or waiver shall be valid only if set forth in an
instrument in writing signed on behalf of such party, and the failure of either

              ANNEX II:  ALEX. BROWN & SONS INCORPORATED OPINION

                                                                  March 12, 1997

Sylvan Learning Systems, Inc.
1000 Lancaster St.
Baltimore, MD 21202

Dear Members of the Board of Directors:

     Sylvan Learning Systems, Inc. ("Sylvan" or the "Company") and National
Education Corporation ("NEC"), a Delaware Corporation, have entered into an
Agreement and Plan of Reorganization dated as of March 12, 1997 (the
"Agreement").  Pursuant to the Agreement, the implementation of which is
contingent on approval by both Sylvan's and NEC's stockholders, Sylvan and NEC
will combine their companies through a merger of a newly formed subsidiary of
Sylvan into NEC (the "Merger").   As a result of the Merger, each share of NEC
common stock issued and outstanding immediately prior to the effective time of
the Merger will be converted into 0.58 shares (the "Exchange Ratio") of common
stock of Sylvan.  We have assumed, with your consent, that the Merger will
qualify for pooling-of-interests accounting treatment and as a tax free
reorganization for federal income tax purposes.  You have requested our opinion
as to whether the Exchange Ratio is fair, from a financial point of view, to
Sylvan.

     Alex. Brown & Sons Incorporated ("Alex. Brown"), as a customary part of its
investment banking business, is engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, private placements and valuations for estate, corporate and other
purposes.  We have acted as financial advisor to the Board of Directors of
Sylvan in connection with the transaction described above and will receive a fee
for our services, a portion of which is contingent upon the consummation of the
Merger and a portion of which becomes payable upon the delivery of this opinion.
We have acted as financial advisor to Sylvan in the past in connection with
various capital raising transactions and other matters, including serving as the
lead-managing underwriter in the December, 1993  initial public offering of the
common stock of Sylvan, as the lead managing underwriter in the December, 1995
follow-on offering of the common stock of Sylvan, and as financial advisor to
Sylvan in its December, 1995 acquisition of Drake Prometric, L.P.  Alex. Brown
maintains a market in the common stock of Sylvan and regularly publishes
research reports regarding the educational services industry and the businesses
and securities of Sylvan and other publicly owned companies in the educational
services industry.  In the ordinary course of business, Alex. Brown may actively
trade the securities of both the Company and NEC for our own account and the
account of our customers and, accordingly, may at any time hold a long or short
position in such securities.

     In connection with this opinion, we have reviewed certain publicly
available financial information and other information concerning Sylvan and NEC
and certain internal analyses and other information furnished to us by Sylvan
and NEC.   We have also held discussions with the members of the senior
managements of Sylvan and NEC regarding the businesses and prospects of their
respective companies and the joint prospects of a combined company.  In
addition, we have (i) reviewed the reported prices and trading activity for the
common stock of both Sylvan and NEC, (ii) compared certain financial and stock
market information for Sylvan and NEC with similar information for certain other
companies in the educational services industry whose securities are publicly
traded, (iii) reviewed the financial terms of certain recent business
combinations in the educational services industry, (iv) reviewed the terms of
the Agreement, and (v) performed such other studies and analyses and considered
such other factors as we deemed appropriate.

     We have not independently verified the information described above and for
purposes of this opinion have assumed the accuracy, completeness and fairness
thereof.  With respect to the information relating to the prospects of Sylvan
and NEC, we have assumed that such information reflects the best currently
available judgments and 
<PAGE>
 
estimates of the managements of Sylvan and NEC as to the likely future financial
performances of their respective companies and of the combined entity. In
addition, we have not made nor been provided with an independent evaluation or
appraisal of the assets or liabilities of Sylvan and NEC, nor have we been
furnished with any such evaluations or appraisals. Our opinion is based on
market, economic and other conditions as they exist and can be evaluated as of
the date of this letter.

     Our advisory services and the opinion expressed herein were prepared solely
for the use of the Board of Directors of Sylvan and do not constitute a
recommendation to any stockholder as to how such stockholder should vote in
connection with the Merger.  We hereby consent, however, to the inclusion of
this opinion in its entirety as an exhibit to any proxy or registration
statement distributed in connection with the Merger.

     Based upon and subject to the foregoing, it is our opinion that, as of the
date of this letter, the Exchange Ratio is fair, from a financial point of view,
to Sylvan.

                                   Very truly yours,

                                   /s/ SCOTT A. WIELER

March 12, 1997


Board of Directors
National Education Corporation
2601 Main Street/Suite 700
Irvine, CA   92614

Members of the Board of Directors:

You have asked our opinion with respect to the fairness to holders of National
Education Corporation ("NEC") common stock ("NEC Common Stock"), from a
financial point of view and as of the date hereof, of the exchange ratio (the
"Exchange Ratio") of .580 shares of Sylvan Learning Systems, Inc. ("Sylvan")
common stock ("Sylvan Common Stock") for each issued and outstanding share of
NEC Common Stock in the Merger described below, pursuant to the Agreement and
Plan of Reorganization, dated as of March 12, 1997, by and between NEC and
Sylvan (the "Agreement").

Under the terms of the Agreement, a wholly-owned subsidiary of Sylvan will merge
with and into NEC (the "Merger"), and upon consummation of the Merger, NEC will
become a wholly-owned subsidiary of Sylvan and the holders of NEC Common Stock
will become holders of Sylvan Common Stock.  As a result of the Merger, each
issued and outstanding share of NEC Common Stock will be converted into .580 of
one fully paid and nonassessable share of Sylvan Common Stock.  Outstanding
options to acquire NEC Common Stock will be converted into options to acquire
Sylvan Common Stock on similar terms.  The Merger is intended to qualify as a
tax-free reorganization within the meaning of Section 368(a) of the Internal
Revenue Code of 1986, as amended.  The terms and conditions of the Merger are
set out more fully in the Agreement.

For purposes of this opinion we have:  (i) reviewed financial information on NEC
and Sylvan furnished to us by both companies, including certain internal
financial analyses and forecasts prepared by the management of NEC and Sylvan;
(ii) reviewed publicly available information with respect to each of NEC and
Sylvan; (iii) held discussions with the senior management of NEC and Sylvan
concerning the businesses, past and current business operations, financial
condition and future prospects of both companies, independently and combined;
(iv) reviewed the stock price and trading history of NEC and Sylvan; (v)
reviewed the valuations of publicly traded companies which we deemed comparable
to NEC and Sylvan; (vi) compared the financial terms of the Merger with other
transactions which we deemed relevant; (vii) analyzed the pro forma earnings per
share of the combined company; (viii) prepared discounted cash flow analyses of
NEC and Sylvan; (ix) reviewed the Agreement; and (x) made such other studies and
inquiries, and reviewed such other data, as we deemed relevant.

In connection with our opinion, we have not, however, independently verified any
of the foregoing information and have relied on all such information being
complete and accurate in all material respects.  Furthermore, we did not obtain
any independent appraisal of the properties or assets and liabilities of NEC or
Sylvan.  With respect to the financial and operating forecasts of NEC and Sylvan
which we have reviewed, we have assumed that such forecasts have been reasonably
prepared in good faith on the basis of reasonable assumptions, reflect the best
available estimates and judgments of such respective managements and that such
projections and forecasts will be realized in the amounts and in the time
periods currently estimated by the managements of NEC and Sylvan.  We have also
assumed that the Merger will be accounted for as a "pooling of interests" under
generally accepted accounting 

                                       1
<PAGE>
 
principles. This opinion is necessarily based upon market, economic, and other
conditions that exist and can be evaluated as of the date of this letter, and on
information available to us as of the date hereof. We are not expressing any
opinion as to what the value of Sylvan Common Stock actually will be when issued
to NEC shareholders pursuant to the Merger or the price at which Sylvan Common
Stock will trade subsequent to the Merger.

BZW has provided certain investment banking and corporate banking services to
NEC from time to time, and has received fees for those services.  Furthermore,
BZW has acted as financial advisor to NEC in connection with the Merger for fees
which are due and payable contingent upon the closing of the Merger.

Our opinion is directed to the Board of Directors of NEC and is not intended to
be and does not constitute a recommendation to any stockholder of NEC as to how
such stockholder should vote on the proposed Merger.

Based upon and subject to the foregoing considerations, it is our opinion that,
as of the date hereof, the Exchange Ratio is fair to holders of NEC Common Stock
from a financial point of view.

Very truly yours,
BZW

                                    PART II

                    INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     (a)  Section 2-418 of the Corporations and Associations Article of the
Annotated Code of Maryland permits a corporation to indemnify its present and
former directors, among others, against judgments, penalties, fines, settlements
and reasonable expenses actually incurred by them in connection with any
proceeding to which they may be made a party by reason of their services in
those or other capacities, unless it is established that (a) the act or omission
of the director or officer was material to the matter giving rise to such
proceeding and (i) was committed in bad faith or (ii) was the result of active
and deliberate dishonesty; or (b) the director or officer actually received an
improper personal benefit in money, property, or services; or (c) in the case of
any criminal proceeding, the director or officer had reasonable cause to believe
that the act or omission was unlawful.  Maryland law permits a corporation to
indemnify a present and former officer to the same extent as a director, and to
provide additional indemnification to an officer who is not also a director.  In
addition, Section 2-418(f) of the Corporations and Associations Article of the
Annotated Code of Maryland permits a corporation to pay or reimburse, in advance
of the final disposition of a proceeding, reasonable expenses (including
attorney's fees) incurred by a present or former director or officer made a
party to the proceeding by reason of his service in that capacity, provided that
the corporation shall have received (a) a written affirmation by the director or
officer of his good faith belief that he has met the standard of conduct
necessary for indemnification by the corporation; and (b) a written undertaking
by or on his behalf to repay the amount paid or reimbursed by the corporation if
it shall ultimately be determined that the standard of conduct was not met.

     The Registrant has provided for indemnification of directors, officers,
employees, and agents in Article Eighth, Section (5) of its charter, as amended.
This provision reads as follows:

          (5)  The Corporation shall indemnify (a) its directors to the 
     full extent provided by the general laws of the State of Maryland now
     or hereafter in force, including the advance of expenses under the
     procedures provided by such laws; (b) its officers to the same extent
     it shall indemnify its directors; and (c) its officers who are not
     directors to such further extent as shall be authorized by the Board
     of Directors and be consistent with law. The foregoing shall not limit
     the authority of the Corporation to indemnify other employees and
     agents consistent with law.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of whether such indemnification by it is against
public policy as expressed in the Securities Act and will be governed by the
final adjudication of such issue.

     (b)  Under Maryland law, a corporation is permitted to limit by provision
in its articles of incorporation the liability of directors and officers, so
that no director or officer of the corporation shall be liable to the
corporation or to any stockholder for money damages except to the extent that
(i) the director or officer actually received an improper benefit in money,
property, or services, for the amount of the benefit or profit in money,
property or services actually received, or (ii) a judgment or other final
adjudication adverse to the director or officer is entered in a proceeding based
on a finding in the proceeding that the director's or officer's action, or
failure to act, was the result of active and deliberate dishonesty and was
material to the cause of action adjudicated in the proceeding.

     Prospectus forming a part of this Registration Statement.

ITEM 22.  UNDERTAKINGS.

     (a)  The undersigned registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement;

               (i)   To include any prospectus required by Section 10(a)(3) of
          the Securities Act of 1933, as amended (the "Securities Act");

               (ii)  To reflect in the prospectus any facts or events arising
          after the effective date of the registration statement (or the most
          recent post-effective amendment thereof) which, individually 

                                      II-2
<PAGE>
 
          or in the aggregate, represent a fundamental change in the
          information set forth in the registration statement;

               (iii)  To include any material information with respect to the
          plan of distribution not previously disclosed in the registration
          statement or any material change to such information in the
          registration statement;

               Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do
          not apply if the information required to be included in a post-
          effective amendment by those paragraphs is contained in periodic
          reports filed with or furnished to the Commission by the registrant
          pursuant to Section 13 or 15(d) of the Securities Exchange Act of
          1934, as amended (the "Exchange Act") that are incorporated by
          reference in the registration statement.

          (2)  That for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

          (3)  To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

     (b)  The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and where interim financial information required to be presented by
Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

     (c)  The undersigned registrant hereby undertakes to respond to requests
for information that is incorporated by reference into the prospectus pursuant
to Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

     (d)  The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

     (e)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

     (f)  The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in the registration
statement shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.
