                                  THE COMPANY

     Sylvan Learning Systems, Inc. (the "Company" or "Sylvan") is a leading
international private provider of educational and testing services.  The Company
delivers a broad array of supplemental and remedial educational services and
computer-based testing through three principal divisions.  The Core Educational
Services division designs and delivers individualized tutorial services to
school-age children and adults at 669 franchised and Company-owned Sylvan
Learning Centers.  Sylvan Prometric, the Company's testing services division,
administers computer-based tests for major organizations, corporations,
professional associations and governmental agencies through its worldwide
network of Testing Centers.  The Contract Educational Services division provides
Sylvan's core educational services under federal and state funding programs to
more than 12,000 students in 89 public schools and more than 38,000 students in
507 non-public schools (including Educational Inroads) and provides on-site
educational and training services to employees of large corporations.  Since
1994, the Company has substantially expanded its business through a combination
of internal growth and acquisitions and has increased revenue and operating
income from $68.7 million and $3.4 million, respectively, in 1994 to $181.9
million and $22.7 million, respectively, in 1996.  Sylvan's 1996 systemwide
revenues were approximately $310.3 million, consisting of $165.1 million from
core educational services ($139.5 million from franchised Learning Centers and
$25.6 million from Company-owned Learning Centers, product sales and franchise
sales fees), $87.0 million from testing services and $58.2 million from contract
educational services.

     Core Educational Services.  The Company's Core Educational Services
division provides supplemental instruction in reading, mathematics and reading
readiness and features an extensive series of standardized diagnostic tests,
individualized instruction, a student motivational system and continued
involvement from both parents and the child's regular school teacher.  As of
September 30, 1997, the Company or its franchisees operated 669 Learning Centers
in 49 states, five Canadian provinces, Hong Kong, South Korea and Guam, with 403
franchisees owning and operating 628 Sylvan Learning Centers and Sylvan owning
and operating 41 Learning Centers.

     Sylvan Prometric Testing Services.  As of September 30, 1997, Sylvan or its
authorized representatives operated 1,908 Testing Centers, 1,207 of which were
located in North America and the remainder in 97 foreign countries.  The Company
enters into contracts directly with various professional licensure, educational
and information technology ("IT") businesses, organizations and agencies, under
which Sylvan receives a fee based upon the number of tests given for those
customers.  Principal customers for the Company's testing services are
Educational Testing Services ("ETS") and, in the IT industry, Microsoft Corp.
and Novell, Inc.  IT customers sponsor worldwide certification programs for
various professionals such as network administrators and engineers, service
technicians and instructors.  Sylvan has been designated as the exclusive
commercial provider of computer-based tests administered by ETS (excluding the
SAT and PSAT) and operates 47 testing centers in 33 countries to facilitate
delivery of international testing for ETS.  The Company also provides testing
services for organizations responsible for licensing broker-dealers, pilots,
aviation mechanics, computer professionals and medical laboratory technicians.
Through the Company's December 1996 acquisition of Wall Street Institute
International B.V. and its affiliates ("Wall Street"), Sylvan now provides live
and computer-based English instruction and testing in Europe and Latin America
through a network of more than 180 franchised and Company-owned centers.

     Contract Educational Services; PACE; Sylvan-at-Work; Caliber Learning
Network, Inc.  Sylvan provides educational services under federal and various
state funding programs to students in 89 public and 507 non-public schools.
Sylvan provides educational and training services to large corporations
throughout the United States, including racial and gender workplace diversity
training and skills improvement programs such as writing, advanced reading,
listening and public speaking, through its wholly-owned subsidiary, The PACE
Group ("PACE"), and the Company's Sylvan-at-Work program.  In November 1996,
Caliber Learning Network, Inc. was formed as a joint initiative of Sylvan and
MCI Telecommunications Corporation to become a worldwide distribution network of
professional education centers equipped with satellite-based video conferencing
and computer network capabilities.  Sylvan currently owns a 10 percent interest
in Caliber Learning Network and has the option to acquire a majority interest in
the future.

Item 15.  Indemnification of Directors and Officers.

     The Company's Charter provides that, to the fullest extent that limitations
on the liability of directors and officers are permitted by the Maryland General
Corporation Law, no director or officer of the Company shall have any liability
to the Company or its stockholders for monetary damages.  The Maryland General
Corporation Law provides that a corporation's charter may include a provision
which restricts or limits the liability of its directors or officers to the
corporation or its stockholders for money damages except: (1) to the extent that
it is provided 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 (2) to the extent that a
judgment or other final adjudication adverse to the person is entered in a
proceeding based on a finding in the proceeding 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 Company's
Charter and By-laws provide that the Company shall indemnify and advance
expenses to its currently acting and its former directors to the fullest extent
permitted by the Maryland General Corporation Law and that the Company shall
indemnify and advance expenses to its officers to the same extent as its
directors and to such further extent as is consistent with law.

     The Charter and By-laws provides that the Company will indemnify its
directors and officers and may indemnify employees or agents of the Company to
the fullest extent permitted by law against liabilities and expenses incurred in
connection with litigation in which they may be involved because of their
offices with the Company.  In addition, the Company's Charter provides that its
directors and officers will not be liable to stockholders for money damages,
except in limited instances.  However, nothing in the Charter or By-laws of the
Company protects or indemnifies a director, officer, employee or agent against
any liability to which he would otherwise be subject by reason of willful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of his office.  To the extent that a director has been
successful in defense of any proceeding, the Maryland General Corporation Law
provides that he shall be indemnified against reasonable expenses incurred in
connection therewith.

*    Incorporated by reference from the Registrant's Registration Statement on
      Form S-1 (No. 33-69558), filed on September 28, 1993.

**   Incorporated by reference from the Company's Annual Report on Form 10-K for
      the Year ended December 31, 1996.

Item 17.  Undertakings.

     (a) 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 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange 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.

     (b) 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 

                                     II-2
<PAGE>
 
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, suite 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.

     (c) The undersigned Registrant hereby undertakes that:

         (1)  For purposes of determining any liability under the Securities Act
of 1933, the information omitted from the form of prospectus filed as part of
this Registration Statement in reliance upon Rule 430A and contained in a form
of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
497(h) under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.

         (2)  For the purpose of determining any liability under the Securities
Act of 1933, each post-effective amendment that contains a form of prospectus
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.

     (d) 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 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 in contained in periodic reports filed 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.

                            ASSET PURCHASE AGREEMENT
                            ------------------------

           THIS ASSET PURCHASE AGREEMENT (this "Agreement"), dated as of the 1st
day of December, 1997, by and among SYLVAN LEARNING SYSTEMS, INC., a Maryland
corporation ("Buyer"), BLOCK TESTING SERVICES L.P., a Delaware limited
partnership ("Block") and BLOCK STATE TESTING SERVICES L.P., a Delaware limited
partnership ("Block State"; and, together with Block, the "Companies").

                                R E C I T A L S:
                                - - - - - - - - 

           WHEREAS, the Companies are engaged in the business of designing,
marketing, selling, distributing and administering paper and pencil tests and
the licensing of individuals thereto (the "Business"); and

           WHEREAS, Buyer desires to acquire, and Sellers desire to sell, the
Assets (as described on Schedule A, attached hereto), for a purchase price which
is established herein, all upon the terms and conditions hereinafter set forth.

           NOW, THEREFORE, and in consideration of the mutual premises and
representations, warranties and covenants and other good and valuable
consideration, the receipt and sufficiency of which being acknowledged, the
parties agree as follows:

           1. SALE AND PURCHASE.  On the Closing Date (as defined in Section 4 
              -----------------  
hereof), in reliance on the representations, warranties, and agreements of the
parties, and on the terms and subject to the conditions set forth herein, the
Companies shall sell, convey, transfer, assign and deliver to Buyer, the Assets,
free and clear of all Encumbrances (as defined in Section 5B hereof), except for
those Encumbrances arising in connection with the Assumed Liabilities (as
defined below). The Assets shall not include those assets identified on Schedule
B, attached hereto (the "Excluded Assets"). Buyer is not assuming any liability
or obligation of the Companies of any nature whatsoever, except as expressly set
forth in Schedule C hereto (the "Assumed Liabilities"). The Companies shall
remain liable and responsible for all obligations and liabilities not expressly
assumed by Buyer hereunder.

           2. PURCHASE PRICE.    The purchase price (the "Purchase Price") for
              --------------    
the Assets shall be Three Hundred Fifteen Thousand Six Hundred Sixty-nine
(315,669) shares of Buyer's common stock, $0.01 par value (collectively, the
"SLS Stock"). Within ten (10) days after the Closing Date, but not before
January 1, 1998, Buyer shall deliver certificates representing an additional
aggregate of 171,279 shares of SLS Stock to Dr. James A. Bax, Dr. Anthony W.
Mitchell and Sue J. Mitchell, as directed by such persons' counsel. Buyer will
also indemnify and hold the Companies harmless from any liability or obligation
of any nature arising out of the promissory notes issued to Laura Jane Bax and
James A. Bax by NAI Merger Corp., and guaranteed by Block.

     No fractional shares of SLS Stock, and no cash in lieu thereof, shall be
issued or delivered in connection with the transactions contemplated by this
Agreement.  When issued, the SLS Stock will be fully paid and non-assessable.

     Notwithstanding anything herein to the contrary, Buyer shall use its best
efforts to file, by March 31, 1998, a registration statement on Form S-3
covering the sale from time to time of the SLS Stock, and shall use its best
efforts to cause the Registration Statement to become effective and to maintain
its effectiveness until the earlier of (i) such time as all of the SLS Stock has
been sold pursuant thereto and (ii) such time as the SLS Stock is eligible for
transfer without restriction pursuant to Rule 144(k) under the Securities Act of
1933, as amended (the "1933 Act") as if not held by an affiliate of Buyer.
Buyer will also furnish to Block with respect to the SLS Stock so registered
under the Registration Statement such number of copies of prospectuses and
preliminary prospectuses in conformity with the 

                                       1
<PAGE>
 
requirements of the 1933 Act and such other documents as Block may reasonably
request in order to facilitate the public sale or other disposition of all or
any of the SLS Stock by Block, provided, however, that the obligation of Buyer
to deliver copies of prospectuses or preliminary prospectuses to Block shall be
subject to the receipt by Buyer of reasonable assurances from Block that Block
will comply with the applicable provisions of the 1933 Act and of such other
securities or blue sky laws as may be applicable in connection with any use of
such prospectuses or preliminary prospectuses. Buyer will file documents
required of Buyer to register or qualify under the securities or blue sky laws
for Block to offer and sell the SLS Stock in all states reasonably requested,
provided, however, that Buyer shall not be required to qualify to do business or
consent to service of process in any jurisdiction in which it is not now so
qualified or has not so consented. Buyer shall promptly notify Block of the
happening of any event of which Buyer has knowledge which results in the
prospectus included in the registration statement, if any, containing an untrue
statement of a material fact or omitting to state a material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading, and Buyer will use its
best efforts to prepare a supplement or amendment to the registration statement
to correct such untrue statement or omission, and deliver a number of copies of
such supplement or amendment to Block as may be reasonably requested. Buyer will
notify Block of the issuance by the Securities and Exchange Commission ("SEC")
of any stop order or other suspension of effectiveness of the registration
statement at the earliest possible time. Buyer will permit Block's counsel to
review the registration statement and all amendments and supplements thereto, at
Block's cost, for a reasonable period time prior to Buyer's filing with the SEC.
Buyer shall bear all expenses in connection with the obligations described in
this Section and the registration of the SLS Stock pursuant to a registration
statement, including registration, listing and filing fees and expenses of
complying with the securities and blue sky laws, brokerage commissions,
placement agent fees, underwriting discounts and fees and expenses, if any, of
counsel or other advisers to Buyer and Block only as the same applies to the
registration contemplated by this Section; provided, however, that such fees and
expenses shall not include brokerage commissions incurred by Block upon the sale
of any of the SLS Stock. Other than as described in this Section, Buyer is under
no other obligations to (i) register any of the SLS Stock on behalf of Block
under the 1933 Act (ii) conduct, arrange or coordinate any distribution of the
SLS Stock, (iii) retain any underwriters in connection with the negotiation
and/or distribution of the SLS Stock or (iv) assist Block in complying with any
exemption from registration of the SLS Stock under the 1933 Act.

     At all times that any of the SLS Stock remains outstanding, Buyer shall
comply with the requirements of Rule 144 under the 1933 Act regarding the
availability of current public information to the extent required to enable any
holder of SLS Stock to sell such shares without registration under the 1933 Act
pursuant to Rule 144.

     The Purchase Price shall be allocated for Federal Income Tax purposes among
the Assets in accordance with Exhibit 1, and each party agrees that, to the
extent permitted by law, it or he shall account for the sale of the Assets in a
manner consistent with such allocation.

           3. PAYMENT OF PURCHASE PRICE.  In full consideration for the 
              -------------------------  
purchase and sale of the Assets pursuant to this Agreement, on January 5, 1998,
Buyer shall pay to Block the entire Purchase Price.

           4. CLOSING.  The consummation of the transactions contemplated 
              -------      
hereby (the "Closing") shall take place within five (5) days after all
conditions precedent have been satisfied, but not later than December 31, 1997,
at 9:00 A.M. (the "Closing Date") at Buyer's offices, or otherwise, on such
other date or place as the parties hereto may mutually agree. The Closing shall
be deemed to be effective for financial accounting purposes at 8:00 a.m. on
December 1, 1997.

           5. THE COMPANIES' REPRESENTATIONS, WARRANTIES, COVENANTS AND 
              ---------------------------------------------------------

                  -------------   
hereto to be executed and delivered by each of the Companies have been duly
authorized by all necessary action and constitute the valid and binding
obligations of each, enforceable in accordance with their respective terms. The
individuals executing this Agreement and the other documents executed in
connection herewith individually and on behalf of each of the Companies have
been duly authorized and have the legal capacity to execute all of such
documents in such capacities. Neither the execution and delivery hereof nor any

provisions hereof or thereof, will: (i) conflict with or result in a material
breach of either of the Companies' charter or formation documents; (ii) violate
in any material respect any statute, law, rule or regulation or any order, writ,
injunction or decree of any court or governmental authority; or (iii) violate or
conflict with or constitute a default in any material respect under (or give

under), any agreement or writing of any nature to which either of the Companies
is a party or by which the Assets may be bound or affected, or result in the
creation of any Encumbrance against or upon any of the Assets under any
agreement or writing to which either of the Companies is a party or by which any
of them or their respective assets may be bound or affected, or (iv) impair or
in any way limit any governmental or official license, approval, permit or
authorization of either of the Companies; provided, however that the Companies
and NAI hereby state, and Buyer acknowledges, that the transfer of the contracts
held by each may be subject to immediate termination because of the transfer
contemplated hereby. Except as disclosed to Buyer, including the consent of the
customers of the Companies which have a written contract with either, no consent
or approval of or notification to any Person is necessary or required in
connection with the execution and delivery by either of the Companies of this
Agreement or any writing relating hereto or the consummation of the transactions
contemplated hereby or thereby.

              d.  Financial Statements.
                  -------------------- 

                        i. The Companies have delivered to Buyer the
consolidated balance sheets and the related statements of income, changes in
shareholders' equity and changes in shareholders' equity and changes in
financial position of both of the Companies, and the notes thereto and the
auditor's report thereon, if applicable, as at and for the fiscal year ended
December 31, 1996 (collectively, the "Historical Financials"). The Historical
Financials are true, correct and complete and present fairly the financial
position of the Companies and the results of their operations, retained earnings
and changes in financial positions as at the dates thereof and for the periods
covered thereby, do not include or omit to state any material fact which renders
them misleading, and have been prepared in conformity with generally accepted
accounting principles applied on a consistent basis, except as may be disclosed
in the reports relating thereto. At the Closing, the Companies and NAI shall
deliver to Buyer a consolidated balance sheet dated as of November 30, 1997 (the
"Closing Balance Sheet") based on the best knowledge and good faith of the
Companies, which shall be prepared on a basis consistent with the Historical
Financials and in accordance with the provisions hereof.

                        ii. Except as indicated to Buyer, the statements of
income included in the Historical Financials do not contain any items of special
or nonrecurring income, and the balance sheets included in the Historical
Financials do not, and the Closing Balance Sheet will not reflect any write-up
or revaluation increasing the book value of any asset.

              e.  Liabilities.
                  ----------- 

                        i. Except as disclosed therein, the liabilities on the
Historical Financials consisted, and the liabilities on the Closing Balance
Sheet will consist, solely of obligations and liabilities incurred by the
Companies either (A) in the ordinary and regular course of Business to Persons
which are not affiliated with the Companies, or (B) in connection with the
purchase by the business of NAI and HHB.

                        ii. As of November 30, 1997 in connection with the
Business, neither of the Companies or NAI will have, any liability or obligation
of any nature whatsoever, including, without limitation, known or unknown, fixed
or contingent, accrued, absolute, matured or unmatured, or any "loss
contingencies" 

                                       4

considered "probable" or "reasonably possible" within the meaning of the
Financial Accounting Standards Board's ("FASB") Statement of Financial
Accounting Standards No. 5, which were not or will not be recorded on the
Historical Financials or the Closing Balance Sheet, as the case may be, or (in
the case of liabilities not required to be recorded on such financial statements
in accordance with generally accepted accounting principles applied on a
consistent basis) specifically disclosed in the footnotes to the Closing Balance
Sheet or otherwise disclosed to Buyer.

                        iii. All reserves and allowances included or to be
included in the Historical Financials and the Closing Balance Sheet are, and
will be, adequate, appropriate and reasonable (in accordance with generally
accepted accounting principles), as has been required by the Companies' outside
auditors.

              f.  Absence of Changes.  Except as otherwise indicated to Buyer 
                  ------------------   
on Schedule 5F, attached hereto, the Business has been operated only in the
ordinary and regular course and there has not been, since June 30, 1997 and

change in its condition, financial or otherwise; (ii) any material and adverse
damage, destruction or loss, whether or not covered by insurance; (iii) other

$100,000.00; (iv) any transfer or application of any assets of either the
Companies or NAI to the payment of any amount payable to or for the benefit of

directly or indirectly, by any owner or by any member of the family of any
owner; (v) any declaration, setting aside or payment of any dividend or other
distribution in respect of any shares of capital stock of the Companies or NAI,
or any direct or indirect redemption, purchase or other acquisition of any such

the Business or any threat of the foregoing; (vii) any sale, transfer or other

           11. CLOSING NOT A WAIVER.  The fact that the parties have chosen to 
               --------------------   
consummate the transactions contemplated hereby shall not act or be deemed or
construed as a waiver of either party or estop either party from pursuing their
respective rights to indemnification hereunder or other remedies for any reason
whatsoever.

           12. POST-CLOSING COVENANTS.
               ---------------------- 

                a.  Restrictive Covenants.
                    --------------------- 

                        i.  Non-disclosure.  Each of the Companies acknowledges
that it has been and will be entrusted with trade secrets, marketing, operating
and strategic plans, customer and supplier lists, proprietary information and
other confidential or specialized data and/or information relative to the
Business, whether now existing or to be developed or created after the Closing
Date (collectively, "Trade Secrets"). Each of the Companies covenants and agrees
that each shall at all times after the date hereof hold in strictest confidence
any and all Trade Secrets that may have come or may come into its possession or
within its knowledge concerning or related to the products, services, processes,
businesses, suppliers, customers and clients of each of the Companies in
connection with the Business and the Assets. Each of the Companies covenants and
agrees that neither it nor any Person controlled by it will for any reason,
directly or indirectly, for itself or for the benefit of any other Person, use,
copy, divulge or otherwise disseminate or disclose any of the Trade Secrets
owned or used by, or licensed to, the Companies or any of their affiliates or
otherwise relating to the Companies or the Business, provided that each of the
Companies may disclose Trade Secrets pursuant to an order by a court of
competent jurisdiction, provided, further, that each of the Companies shall give
Buyer notice of such order and any court pleading requesting such disclosure, in
order to provide Buyer with an opportunity to prevent such disclosure or procure
an appropriate protective order.

                        ii.  Customers.  Each of the Companies acknowledges that
customers and customer accounts of the Companies comprising the Assets will,
after the Closing, at all times be the sole and separate property of Buyer, in
which neither of the Companies have any rights whatsoever, and all activities of
or work performed by neither of the Companies for or on behalf of Buyer in the
future will be performed solely for the benefit of Buyer and the goodwill
resulting from such efforts by any of the Companies is and at all times will be
the sole and separate property of Buyer, which goodwill is intended to be
protected, in part, by this Section.

                        iii.  Non-Solicitation; Non-Hire.  Each of the Companies
agrees that from the Closing Date and continuing for a period (the "Non-Compete
Period") of five (5) years from the Closing Date, neither they nor any person or
enterprise controlled by them will solicit or, without Buyer's prior written
consent, hire, for employment or any other reason any person who, at any time
within one (1) year prior to the time of the act of solicitation, or hire, was
employed by Buyer or either of the Companies or NAI.

                        iv.  Non-Competition by Companies.  During the Non-
Compete Period, each of the Companies agree that none of them nor any person or
enterprise controlled by them will become a stockholder, director, officer,
agent, employee or representative of or consultant to a corporation or member of
a partnership, engage as a sole proprietor in any business, act as a consultant
to any of the foregoing or otherwise engage, directly or 

                                       12
<PAGE>
 
indirectly, in any enterprise which competes with the Business anywhere in the
continental United States; provided, however, that the foregoing shall not
prohibit (i) the ownership of less than two percent (2%) of the outstanding
shares of the stock of any corporation engaged in any business, which shares are
regularly traded on a national securities exchange or in any over-the-counter
market, and (ii) the ownership and operation of Registry Services International,
L.P..

                        v.  Relief, Reformation; Severability.  The parties
agree that the covenants contained in this Section 12A are separate and are
reasonable in their scope and duration and may be enforced by specific
performance or otherwise. The parties shall not raise any issue of
reasonableness as a defense in any proceeding to enforce any of the covenants
herein. Notwithstanding the foregoing, in the event that a covenant included in
this Section 12A shall be deemed by any court to be unreasonably broad in any
respect, the court which makes such finding shall modify such covenant for the
purpose of making such covenant reasonable in scope and duration. The validity,
legality or enforceability of the remaining provisions of this Agreement shall
not be affected by any such modification.

                        vi.  Remedies.  The parties acknowledge that any breach
of the restrictive covenants herein will cause irreparable harm to the other,
and that such harm will be difficult if not impossible to ascertain. Therefore,
if any action or proceeding is commenced by or on behalf of any party to enforce
the provisions hereof, such party shall be entitled to equitable relief,
including injunction, against any actual or threatened breach hereof, and any
damages arising therefrom including, without limitation, reasonable fees of its
attorneys and their support staff and all other costs and expenses incurred by
the other party in good faith in connection therewith without bond and without
liability should such relief be denied, modified or vacated. Neither the right
to obtain such relief nor the obtaining of such relief shall be exclusive of or
preclude any party from any other remedy. Each party hereby waives the claim or
defense to an action for equitable relief by the other that the other has an
adequate remedy at law or has not been or is not being irreparably injured by
such breach. FURTHERMORE, EACH PARTY HEREBY WAIVES ANY RIGHT TO HAVE A JURY
PARTICIPATE IN RESOLVING ANY DISPUTE OF ANY NATURE ARISING OUT OF, CONNECTED
WITH, RELATED OR INCIDENTAL TO THE RESTRICTIVE COVENANTS CONTAINED IN SECTION
12A HEREOF. INSTEAD, ANY DISPUTES RESOLVED IN COURT WILL BE RESOLVED IN A BENCH
TRIAL WITHOUT A JURY.

           13. INDEMNIFICATION.
               --------------- 

                a.  The Companies jointly and severally agree to indemnify and
hold harmless Buyer against any and all damages, losses, settlement payments,
obligations, liabilities, claims, actions, causes of action, suits, proceedings,
costs of investigations, demands, assessments, judgments, Encumbrances and costs
and expenses (including, without limitation, attorneys' fees, interest,
penalties and all costs associated therewith incurred by such party in good
faith) (collectively, "Losses") suffered, sustained, incurred or paid by any
indemnified party, to which such indemnified party may become subject under any
federal, state or local law, rule or regulation, at common law or otherwise
(including in settlement of any litigation), only to the extent that such Losses
(or actions in respect thereof) exceed in the aggregate $250,000 (net of
insurance proceeds paid with respect thereto and tax benefits derived therefrom)
and arise out of or are based upon (i) any untrue or inaccurate statement made
by either of the Companies herein, including the information included in any
Exhibit hereto; (ii) the claims of any broker or finder engaged by either of the
Companies; (iii) the nonfulfillment or breach or alleged nonfulfillment or
breach of any agreement or covenant of any of the Companies; (iv) the assertion
against any indemnified party or any of their assets of any liability or
obligation of any of the Companies which is not an Assumed Liability or related
to an Assumed Liability; and (v) all currently outstanding matters of
litigation, or claims currently threatened against either of the Companies; and
will reimburse each indemnified party for any legal or other cost or expense
incurred by such party in good faith in connection with investigating or
defending any such loss, claim, damage, liability or action. Notwithstanding
anything herein to the contrary, the Companies shall have no indemnity
obligation whatsoever to Buyer based in whole or in part because of the failure
to procure consents to the assignments of any of the Contracts from the
Companies to Buyer. The indemnity obligation described in this Section 13A shall
be the sole and exclusive remedy of Buyer, and shall not survive the Closing.

                                       13
<PAGE>
 
                b.  Buyer will indemnify and hold harmless each of the Companies
against any and all Losses suffered, sustained, incurred or paid by any
indemnified party, to which such indemnified party may become subject under any
federal, state or local law, rule or regulation, at common law or otherwise
(including in settlement of any litigation), insofar as such Losses (or actions
in respect thereof) arise out of or are based upon (i) any untrue or inaccurate
statement or alleged untrue or inaccurate statement of any material fact made by
Buyer herein, including the information included in any Exhibit hereto; (ii) the
claims of any broker or finder engaged by Buyer; (iii) the nonfulfillment or
breach or alleged nonfulfillment or breach of any agreement or covenant of
Buyer, and; (iv) the assertion against any indemnified party or any of their
assets of any liability or obligation of Buyer, or relating to Buyer's
operations or any of its assets, including the Assumed Liabilities; and will
reimburse each indemnified party for any legal or other expenses reasonably
incurred by such party in connection with investigating or defending any such
loss, claim, damage, liability or action. The indemnity obligation described in
this Section 13B shall be the sole and exclusive remedy of the Companies.

matters described above, and that this paragraph shall be grounds for dismissal
of any court action commenced by any party with respect to a dispute arising out
of such matters.

     THE PARTIES AGREE THAT ANY ARBITRATION SHALL BE GOVERNED BY AND PURSUANT TO
THE FEDERAL ARBITRATION ACT, AS AMENDED, AND THE RULES AND REGULATIONS

criticize or denigrate the talents, skills, prospects, abilities, integrity or
character of the other parties hereto, or such parties' management, directors,
employees, agents or representatives (including those of Buyer's affiliates).
The provisions of this Section shall survive the execution and termination
hereof, irrespective of the reason for such termination.

                q.  Non-Recourse Obligations.  Buyer specifically acknowledges 
                    ------------------------  
and agrees that, notwithstanding any provision to the contrary contained in this
Agreement, except as set forth below in the paragraph preceding the signature
block of NAI, its only recourse for enforcement of the covenants and agreements
of the Companies contained herein, shall be against the Assets of the Companies
and that all of such covenants and agreements of the Companies contained herein,
including without limitation the indemnity obligations of the Companies
contained in Section 13 hereof, are and shall be non-recourse to both the
general and limited partners of the Block. The foregoing shall in no way be

corporation ("Sub"), Block, NAI, Bax & Associates, Inc., a Florida corporation

the Companies and Buyer and their respective counsel, and each provision hereof
has been subject to the mutual consultation, negotiation and agreement of such
parties and counsel, and shall not be construed for or against any party hereto.

on the part of any Person (as defined below), Block, as holder of all of the
issued and outstanding shares of stock of NAI (collectively, the "Shares"),

     No fractional shares of SLS Stock, and no cash in lieu thereof, shall be
issued or delivered in connection with the transactions contemplated by this
Agreement.  When issued, the SLS Stock will be fully paid and non-assessable.

     Notwithstanding anything herein to the contrary, Sylvan shall use its best
efforts to file, by March 31, 1998, a registration statement on Form S-3
covering the sale from time to time of the SLS Stock, and shall use its best
efforts to cause the Registration Statement to become effective and to maintain
its effectiveness until the earlier of (i) such time as all of the SLS Stock has
been sold pursuant thereto and (ii) such time as the SLS Stock is eligible for
transfer without restriction pursuant to Rule 144(k) under the Securities Act of
1933, as amended (the "1933 Act") as if not held by an affiliate of Sylvan.
Sylvan will also furnish to Block with respect to the SLS Stock so registered
under the Registration Statement such number of copies of prospectuses and
preliminary prospectuses in conformity with the requirements of the 1933 Act and
such other documents as Block may reasonably request in order to facilitate the
public sale or other disposition of all or any of the SLS Stock by Block,
provided, however, that the obligation of Sylvan to deliver copies of
prospectuses or preliminary prospectuses to Block shall be subject to the
receipt by Sylvan of reasonable assurances from Block that Block will comply
with the applicable provisions of the 1933 Act and of such other securities or
blue sky laws as may be applicable in connection with any use of such
prospectuses or preliminary prospectuses.  Sylvan will file documents required
of Sylvan to register or qualify under the securities or blue sky laws for Block
to offer and sell the SLS Stock in all states reasonably requested, provided,
however, that Sylvan shall not be required to qualify to do business or consent
to service of process in any jurisdiction in which it is not now so qualified or
has not so consented.  Sylvan shall promptly notify Block of the happening of
any event of which Sylvan has knowledge which results in the prospectus included
in the registration statement, if any, containing an untrue statement of a
material fact or omitting to state a material fact required to be stated therein
or necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, and Sylvan will use its best efforts
to prepare a supplement or amendment to the registration statement to correct
such untrue statement or omission, and deliver a number of copies of such
supplement or amendment to Block as may be reasonably requested.  Sylvan will
notify Block of the issuance by the Securities and Exchange Commission ("SEC")
of any stop order or other suspension of effectiveness of the registration
statement at the earliest possible time.  Sylvan will permit Block's counsel to
review the registration statement and all amendments and supplements thereto, at
Block's cost, for a reasonable period time prior to Sylvan's filing with the
SEC.  Sylvan shall bear all expenses in connection with the obligations
described in this Section and the registration of the SLS Stock pursuant to a
registration statement, including registration, listing and filing fees and
expenses of complying with the securities and blue sky laws, brokerage
commissions, placement agent fees, underwriting discounts and fees and expenses,
if any, of counsel or other advisers to Sylvan and Block only as the same
applies to the registration contemplated by this Section; provided, however,
that such fees and expenses shall not include brokerage commissions incurred by
Block upon the sale of any of the SLS Stock.  Other than as described in this
Section, Sylvan is under no other obligations to (i) register any of the SLS
Stock on behalf of Block under the 1933 Act (ii) conduct, arrange or coordinate
any distribution of the SLS Stock, (iii) retain any underwriters in connection
with the negotiation and/or distribution of the SLS Stock or (iv) assist Block
in complying with any exemption from registration of the SLS Stock under the
1933 Act.

     At all times that any of the SLS Stock remains outstanding, Sylvan shall
comply with the requirements of Rule 144 under the 1933 Act regarding the
availability of current public information to the extent required to enable any
holder of SLS Stock to sell such shares without registration under the 1933 Act
pursuant to Rule 144.

     3.  DELIVERY OF SLS STOCK.  All of the SLS Stock shall be deemed issued as
         ---------------------

     10.  POST-CLOSING COVENANTS.
          ---------------------- 

           a.  Restrictive Covenants.
               --------------------- 

                 i.   Non-disclosure.  Each of the Companies acknowledges that
it has been and will be entrusted with trade secrets, marketing, operating and
strategic plans, customer and supplier lists, proprietary information and other
confidential or specialized data and/or information relative to the Business,
whether now existing or to be developed or created after the Closing Date
(collectively, "Trade Secrets"). Each of the Companies covenants and agrees that
each shall at all times after the date hereof hold in strictest confidence any
and all Trade Secrets that may have come or may come into its possession or
within its knowledge concerning or related to the products, services, processes,
businesses, suppliers, customers and clients of each of the Companies in
connection with the Business and the Assets. Each of the Companies covenants and
agrees that neither it nor any Person controlled by it will for any reason,
directly or indirectly, for itself or for the benefit of any other Person, use,
copy, divulge or otherwise disseminate or disclose any of the Trade Secrets
owned or used by, or licensed to, the Companies or any of their affiliates or
otherwise relating to the Companies or the Business, provided that each of the
Companies may disclose Trade Secrets pursuant to an order by a court of
competent jurisdiction, provided, further, that each of the Companies shall give
Sylvan notice of such order and any court pleading requesting such disclosure,
in order to provide Sylvan with an opportunity to prevent such disclosure or
procure an appropriate protective order.

                 ii.  Customers.  Each of the Companies acknowledges that
customers and customer accounts of the Companies comprising the Assets will,
after the Closing, at all times be the sole and separate property of Sylvan, in
which neither of the Companies have any rights whatsoever, and all activities of
or work performed by neither of the Companies for or on behalf of Sylvan in the
future will be performed solely for the benefit of Sylvan and the goodwill
resulting from such efforts by any of the Companies is and at all times will be
the sole and separate property of Sylvan, which goodwill is intended to be
protected, in part, by this Section.

                 iii. Non-Solicitation; Non-Hire. Each of the Companies agrees
that from the Closing Date and continuing for a period (the "Non-Compete
Period") of five (5) years from the Closing Date, neither they nor any person or
enterprise controlled by them will solicit or, without Sylvan's prior written
consent, hire, for employment or any other reason any person who, at any time
within one (1) year prior to the time of the act of solicitation, or hire, was
employed by Sylvan or either of the Companies.

                 iv.  Non-Competition by Companies. During the Non-Compete
Period, each of the Companies agree that none of them nor any person or
enterprise controlled by them will become a stockholder, director, officer,
agent, employee or representative of or consultant to a corporation or member of
a partnership, engage as a sole proprietor in any business, act as a consultant
to any of the foregoing or otherwise engage, directly or indirectly, in any
enterprise which competes with the Business anywhere in the continental United
States; provided, however, that the foregoing shall not prohibit (i) the
ownership of less than two percent (2%) of the outstanding shares of the stock
of any corporation engaged in any business, which shares are regularly traded on
a national securities exchange or in any over-the-counter market, and (ii) the
ownership and operation of Registry Services International, L.P.

                 v.   Relief, Reformation; Severability. The parties agree that
the covenants contained in this Section 12A are separate and are reasonable in
their scope and duration and may be enforced by specific performance or
otherwise. The parties shall not raise any issue of reasonableness as a defense
in any proceeding to enforce any of

                                       12
<PAGE>
 
the covenants herein. Notwithstanding the foregoing, in the event that a
covenant included in this Section 12A shall be deemed by any court to be
unreasonably broad in any respect, the court which makes such finding shall
modify such covenant for the purpose of making such covenant reasonable in scope
and duration. The validity, legality or enforceability of the remaining
provisions of this Agreement shall not be affected by any such modification.

                 vi.  Remedies.  The parties acknowledge that any breach of the
restrictive covenants herein will cause irreparable harm to the other, and that
such harm will be difficult if not impossible to ascertain. Therefore, if any
action or proceeding is commenced by or on behalf of any party to enforce the
provisions hereof, such party shall be entitled to equitable relief, including
injunction, against any actual or threatened breach hereof, and any damages
arising therefrom including, without limitation, reasonable fees of its
attorneys and their support staff and all other costs and expenses incurred by
the other party in good faith in connection therewith without bond and without
liability should such relief be denied, modified or vacated. Neither the right
to obtain such relief nor the obtaining of such relief shall be exclusive of or
preclude any party from any other remedy. Each party hereby waives the claim or
defense to an action for equitable relief by the other that the other has an
adequate remedy at law or has not been or is not being irreparably injured by
such breach. FURTHERMORE, EACH PARTY HEREBY WAIVES ANY RIGHT TO HAVE A JURY
PARTICIPATE IN RESOLVING ANY DISPUTE OF ANY NATURE ARISING OUT OF, CONNECTED
WITH, RELATED OR INCIDENTAL TO THE RESTRICTIVE COVENANTS CONTAINED IN SECTION
12A HEREOF. INSTEAD, ANY DISPUTES RESOLVED IN COURT WILL BE RESOLVED IN A BENCH
TRIAL WITHOUT A JURY.

costs of investigations, demands, assessments, judgments, Encumbrances and costs
and expenses (including, without limitation, attorneys' fees, interest,
penalties and all costs associated therewith incurred by such party in good
faith) (collectively, "Losses") suffered, sustained, incurred or paid by any
indemnified party, to which such indemnified party may become subject under any
federal, state or local law, rule or regulation, at common law or otherwise
(including in settlement of any litigation), only to the extent that such Losses
(or actions in respect thereof) exceed in the aggregate $250,000 (net of
insurance proceeds paid with respect thereto and tax benefits derived therefrom)
and arise out of or are based upon (i) any untrue or inaccurate statement made
by either of the Companies herein, including the information included in any
Exhibit hereto; (ii) the claims of any broker or finder engaged by either of the
Companies; (iii) the nonfulfillment or breach or alleged nonfulfillment or

obligation of any of the Companies which is not an Assumed Liability or related

litigation, or claims currently threatened against either of the Companies; and
will reimburse each indemnified party for any legal or other cost or expense
incurred by such party in good faith in connection with investigating or
defending any such loss, claim, damage, liability or action. Notwithstanding
anything herein to the contrary, the Companies shall have no indemnity
obligation whatsoever to Sylvan based in whole or in part because of the failure
to procure consents to the assignments of any of the Contracts from the
Companies to Sylvan. The indemnity obligation described in this Section 13A
shall be the sole and exclusive remedy of Sylvan, and shall not survive the
Closing.

           b.  Sylvan will indemnify and hold harmless each of the Companies
against any and all Losses suffered, sustained, incurred or paid by any
indemnified party, to which such indemnified party may become subject under any
federal, state or local law, rule or regulation, at common law or otherwise
(including in settlement of any litigation), insofar as such Losses (or actions
in respect thereof) arise out of or are based upon (i) any untrue or inaccurate
statement or alleged untrue or inaccurate statement of any material fact made by
Sylvan herein, including the information included in any Exhibit hereto; (ii)
the claims of any broker or finder engaged by Sylvan; (iii) the nonfulfillment
or breach or alleged nonfulfillment or breach of any agreement or covenant of
Sylvan, and; (iv) the assertion against any indemnified party or any of their
assets of any liability or obligation of Sylvan, or relating to Sylvan's
operations or any of its assets, including the Assumed Liabilities; and will
reimburse each indemnified party 

                                       13
<PAGE>
 
for any legal or other expenses reasonably incurred by such party in connection
with investigating or defending any such loss, claim, damage, liability or
action. The indemnity obligation described in this Section 13B shall be the sole
and exclusive remedy of the Companies.

                        AGREEMENT FOR PURCHASE OF STOCK

     Agreement for Purchase of Stock (this "Agreement"), effective as of October
1, 1997 by and among Sylvan Learning Systems, Inc., a Maryland corporation (the
"Purchaser") and Leslie Zalk, Kathleen Gillan, Carleen Garza, Evelyn M. Tuey,
Stephanie Thomas, Merida M. Phillips, Kay L. Bennett, and Patricia McSwain (the
"Stockholders").

                                  WITNESSETH:

     The Stockholders, in aggregate, own seventy-five percent (75.0%) of all of
the issued and outstanding capital stock of PMZ, Inc., a California corporation
(the "Company").  The remaining 25% is owned by Purchaser.  The Purchaser and
Stockholders wish to enter into an agreement for the acquisition of
Stockholders' interest and stock in the Company, and Purchaser makes such
acquisition as part of its plan and effort to acquire the Company and all shares
outstanding therein in a transaction or series of transactions qualifying as a
tax-free reorganization under Section 368(a)(1)(A) of the Code.

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

     1. REPRESENTATIONS AND WARRANTIES OF THE PURCHASER.  The Purchaser hereby
represents and warrants to the Stockholders as follows:

          1.1  Organization and Standing.  The Purchaser is a corporation duly
               -------------------------                                      
organized, validly existing and in good standing under the laws of the State of
Maryland and has the corporate power to carry on its business as it is now being
conducted and to own or hold under lease the properties and assets it now owns
or holds under lease.  The Purchaser has at all times in the past operated and
used its assets in material compliance with, and currently is not in violation
of, and has obtained all material licenses and permits required by, any law,
rule or regulation.

Stockholders copies of the Purchaser's audited consolidated financial statements
for the fiscal years ended December 31, 1995 and 1996 and unaudited consooidated
financial statements for the six month period ending June 30, 1997.  These
financial statements are true and complete in all material respects, have been
prepared in accordance with generally accepted accounting principles ("GAAP")
consistently followed throughout the periods covered by such statements (except
as may be stated in the explanatory notes to such statements), and present
fairly the consolidated financial position and results of operations of the
Purchaser at the dates of such statements and for the periods covered thereby.
The Purchaser also has delivered to the Stockholders copies of its Annual Report
on Form 10-K for the year ended December 31, 1996, its proxy statement dated
June 7, 1997, and all other reports or documents required to be filed with the
Securities and Exchange Commission pursuant to Sections 13(a) or 15(d) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), after the
filing of such Annual Report on Form 10-K and prior to the date of this
Agreement.

          1.3  No Conflict With Other Documents.  Neither the execution and
               --------------------------------                            
delivery of this Agreement nor the carrying out of the transactions contemplated
hereby will result in any violation, termination or modification of, or be in
conflict with, the Purchaser's Charter or By-Laws, or, any terms of any
contract, instrument or other agreement to which the Purchaser is a party or by
which it or any of its properties is bound or affected, or any law, rule,
regulation, license, permit, judgment, decree or order applicable to the
Purchaser or by which any of its properties or assets are bound or affected, or
result in any breach of or constitute a default (or with notice or lapse of time
or both would become a default) under, or give to others any rights of
termination, amendment, acceleration or 

                                       1

cancellation, or result in the creation of any lien, charge or encumbrance upon
any of its properties or assets, except where such event or occurrence would
not, singly or in the aggregate, have a material adverse on the Purchaser.

          1.4  Brokers and Advisors.  The Purchaser has taken no action which
               --------------------                                          
would give rise to a valid claim against any party hereto for a brokerage
commission, finder's fee, counseling or advisory fee, or like payment.


          1.5  Validity of Common Stock.  The shares of Purchaser's Common Stock
               ------------------------

               ----------------------------------                             
Purchaser is aware of no events, actions or conditions which would prevent the
Purchaser from being able to comply with the provisions of Section 11.1(a) of
this Agreement, and will use its best efforts to continue to be eligible to
comply with the provisions of Section 11.1(a).

          1.7  Authority.  The execution, delivery and performance of this
               ---------

               -----------------------                                    
events or conditions relating to the Purchaser which would preclude the
Stockholders from treating the   share exchange as a tax-free reorganization
under Section 368(a)(1)(A) of the Code.

</TABLE>

     plus any additional retail Sylvan Learning Centers that Purchaser shall
establish in the territory covered by Sylvan License Agreements 543 and 595 as
of the Closing.  Net earnings shall be calculated on the accrual method, center
by center, in accordance with generally accepted accounting principles,
consistently applied from 1997 to 1998, and shall mean (whether any center has,
in fact, a profit or a loss) the yearly revenues attributable to all operations

                                       7
<PAGE>
 
conducted in those centers less the sum of 1) all operating expenses directly
incurred in operating the centers 2) advertising expenses incurred by Purchaser
and allocated to the centers for local, Los Angeles co-op and national
advertising contributions, 3) depreciation and amortization charges against
capitalized items in the centers and intangibles on the books for the centers
and 4) direct internal administrative overhead expense incurred by Purchaser for
supervision of the corporate retail centers in accordance with Purchaser's
previous practices in charging such expenses to Purchaser's retail Sylvan
Learning centers (i.e. the K. Killian and staff overhead account).  Revenues
attributable to any STC operations shall be calculated as though the STC in the
center had been operated as an STC Agent-operated center.  None of Purchaser's
revenues or expenses attributable to Mindsurf operations or public/non-public
school contract services shall be taken into account in determining PMZ Retail
Group net earnings.  The $600,000 net earnings target shall be subject to
ratable adjustment (upwards or downwards) in the event any of the Learning
Centers listed above is sold prior to December 31, 1998 by taking into account
that center's contribution to calendar year 1997 net earnings (stated on an
accrual basis) for all of the centers combined.  By way of example, if a center
contributed 20% of the total centers' net earnings for 1997, and is sold January
1, 1998, then the $600,000 net earnings target will be reduced by $120,000 (20%
of $600,000). If a center had a loss in 1997 equal to -5% of the total centers'
net earnings for 1997, and is sold January 1, 1998, the $600,000 net earnings
target will be increased by $30,000 (5% of $600,000).

agree to sell, and the Purchaser agrees to buy, at the Closing, the

1, 19989 if the audited financial statement for the PMZ Retail Group Sylvan
Learning Centers reflects that the ending balance of deferred tuition revenues
as of 12/31/97 is less than $350,000.

by this Agreement shall take place at the offices of the Company in Irvine,

               -----------------------------------                          
covenant and agree severally, but not jointly, to indemnify and hold harmless
the Purchaser and its respective successors and assigns, at all times from and
after the date of Closing against and in respect of the following:

                                       9
<PAGE>
 
               (i)    any liability, loss, damage, cost or expense resulting
     from any misrepresentation, breach of representation or warranty or breach
     or non-fulfillment of any agreement or covenant on the part of the
     Stockholders under this Agreement, or from any inaccuracy or
     misrepresentation in or omission from any certificate or other instrument
     or document furnished or to be furnished by the Company or the Stockholders
     hereunder;

               (ii)   To the extent not accrued or reflected in the Financial
     Statements covering the period prior to the Closing, any liabilities or
     obligations of the Company or the Stockholders arising from operations of
     the Company prior to the Closing, including but not limited to federal,
     state or local income tax or, any personal property, FICA, withholding,
     excise, unemployment, sales or franchise taxes.

               (iii)  all claims, actions, suits, proceedings, demands,
     assessments, judgments, costs, reasonable attorneys' fees and expenses of
     any nature incident to any of the matters indemnified against pursuant to
     this Section 9.1, including, without limitation, all such costs and
     expenses incurred in the defense thereof or in the enforcement of any
     rights of the Purchaser hereunder.

     Each stockholder's liability under this Section 9.1 and Section 11.3 shall
be limited to their respective percentage shown on Schedule 1.2 hereof, and in
no event shall any individual stockholder's liability exceed the result of
multiplying such percentage times $903,000.

               9.2.  Notice and Defense.  The Purchaser shall notify the
                     ------------------
Stockholders of any asserted liability, damage, loss or expense claimed to give
rise to indemnification hereunder and the Stockholders shall have an initial
right to defend, compromise and settle such matter provided that the Purchaser
is fully protected from any liability, loss damage, cost or expense in
connection therewith. Within ten (10 days of receipt of such notice,
Stockholders shall respond in writing as to whether Stockholders will engage
counsel at Stockholders' expense to defend the claim. If Stockholders do not
respond, or affirmatively decline to defend the claim or disputes its obligation
to indemnify, the Purchaser shall then have, at its election, the right to
compromise or defend any such matter at the Stockholders' sole cost and expense
through counsel chosen by the Purchaser and reasonably acceptable to the
Stockholders; provided, however, that any such compromise or defense shall be
conducted in a manner which is reasonable and the Stockholders shall in all
events have a right to veto any such compromise or defense which might increase
the potential liability of, or create a new liability for, the Stockholders
(other than under Section 9.1). Each party agrees in all cases to cooperate with
the defending party and its or his counsel in the compromise of or defending of
any such liabilities or claims. In addition, the non defending party shall at
all times be entitled to monitor such defense through the appointment, at its or
his own cost and expense, of advisory counsel of its own choosing. As to any
claim paid by the Purchaser for which any of the Stockholders has indemnity
liability under this Section 9, and which the Stockholder does not reimburse
Purchaser within five (5) days following demand for reimbursement by Purchaser,
Purchaser may (if it is then holding any of such Stockholder's Purchaser Common
Stock) offset the amount of the Stockholder's liability on the claim paid
against the shares of such Purchaser Common Stock retained by Purchaser,
canceling that number of shares that then have a fair market value equal to the
amount paid (for purposes of this section, fair market value shall mean the
closing price of the stock as reported by the Wall Street Journal for the
trading date immediately preceding the day reimbursement from the Stockholder is
due). For purposes of determining the stockholder's liability for a shortfall in
1998 net earnings under the covenant of Section 4.6, each stockholder's
liability shall equal the product of multiplying their respective percentage
interest shown in Schedule 1.2 times 35/60ths times the total amount by which
$600,000 exceeds actual net earnings, but in no event shall any stockholders'
liability pursuant to Section 4.6 exceed the value of the shares held by
Purchaser at the time the liability is determined.

               9.3.  Indemnification by the Purchaser.  From and after the
                     --------------------------------
Closing Date, the Purchaser hereby covenants and agrees to indemnify and hold
harmless the Stockholders against and in respect of the following:

                     (i) any liability, loss, damage, cost or expense resulting
from any misrepresentation, breach of warranty or non-fulfillment of any
agreement or covenant on the part of Purchaser under this Agreement, or

                                      10
<PAGE>
 
from any misrepresentation in or omission from any certificate or other
instrument or document furnished or to be furnished by the Purchaser hereunder;
and

                (ii)   Any liabilities or obligations of the Company arising
from operations of the Company after the Closing, including but not limited to
federal, state or local income tax or, any personal property, FICA, withholding,
excise, unemployment, sales or franchise taxes.

                (iii)  all claims, actions, suits, proceedings, demands,
assessments, judgments, costs, reasonable attorneys' fees and expenses of any
nature incident to any of the matters indemnified against pursuant to this
Section 9.3, including without limitation, all such costs and expenses incurred
in the defense thereof or in the enforcement of any rights of the Stockholders
hereunder.

     The Stockholders shall notify the Purchaser of any asserted liability,
damage, loss or expense claimed to give rise to indemnification hereunder and
thereafter the Purchaser shall have the right to defend, compromise and settle
such matter provided that the Stockholders are fully protected from any
liability, loss, damage, cost or expense in connection therewith.

sentence, neither the Purchaser, on the one hand, nor the Stockholders, on the
other, shall have any liability with respect to any matter if notice of a claim
has not been provided on or prior to December 31, 1998.  Notwithstanding the

one hand, or the Company or the Stockholders, on the other hand, may have which
arises from any fraud or willful misconduct on the part of the Stockholders or
the Company, or any representative of either, on the one hand, and the Purchaser
or any representative of it, on the other hand, shall continue in full force and
effect without limitation until expiration of the statute of limitations
applicable thereto.

indemnified party shall be entitled to indemnification for all losses sustained,
incurred, paid or required to be paid by such indemnified party in excess of the
$9,000; and in no event shall any party to this Agreement be entitled to
indemnification for a single loss or an aggregate of several losses which
exceeds $903,000.

Stock is required to be delivered under the Securities Act, any event has
occurred the result of which is that any such prospectus then in effect would

any material fact necessary to make the statements therein not misleading in
light of the circumstances in which they were made;

                (e) advise the Stockholders, promptly after it shall receive

now so qualified or has not so consented; and

                (h) bear all expenses in connection with the procedures in
paragraphs (a) through (g) of this Section 11.1 and the registration of the
Purchaser Common Stock pursuant to each of the Shelf Registration Statements,
other than fees and expenses, if any, of counsel or other advisers to the
Stockholders.

covenant on the part of Buyer under this Agreement, or from any
misrepresentation in or omission from any certificate or other instrument or
document furnished or to be furnished by the Buyer hereunder; and

           (ii) any damage, loss or claim which arises out of any liabilities or
obligations of the Buyer, included but not limited to federal, state or local
income taxes, FICA, withholding, excise, unemployment, sales or franchise taxes,

including without limitation, all such costs and expenses incurred in the
defense thereof or in the enforcement of any rights of the Stockholders
hereunder.

           The Stockholders shall notify the Buyer of any asserted liability,
damage, loss or expense claimed to give rise to indemnification hereunder and

           C.   No Conflict With Other Documents.  Neither the execution and
                --------------------------------                            
delivery of this Agreement nor the carrying out of the transactions contemplated
hereby will result in any violation, termination or modification of, or be in
conflict with, the Buyer's Charter or By-Laws, or, any terms of any contract,
instrument or other agreement to which the Buyer is a party or by which it or
any of its properties is bound or affected, or any law, rule, regulation,
license, permit, judgment, decree or order applicable to the Buyer or by which
any of its properties or assets are bound or affected, or result in any breach
of or constitute a default (or with notice or lapse of time or both would become
a default) under, or give to others any rights of termination, amendment,
acceleration or cancellation, or result in the creation of any lien, charge or
encumbrance upon any of its properties or assets, except where such event or
occurrence would not, singly or in the aggregate, have a material adverse on the
Buyer.

           D.   Brokers and Advisors.  The Buyer has taken no action which would
                --------------------

be issued and delivered by the Buyer in connection with the acquisition of the

                ----------------------------------                             
Buyer is aware of no events, actions or conditions which would prevent the Buyer
from being able to comply with the provisions of Section 11.1(a) of this
Agreement, and will use its best efforts to continue to be eligible to comply
with the provisions of Section 11.1(a).
 
           G.   Registration Statement on Form S-3.  The Buyer will use its best
                ----------------------------------                              
efforts to meet the requirements for eligibility set forth in paragraph A. of

     10.2  The Seller and each of the Stockholders hereby jointly and severally
represent and warrant to the Buyer as follows:

           A.   Investment Intent.  It is understood that the shares of Sylvan
                -----------------                                             
Common Stock to be delivered to the Seller pursuant to this Agreement are not
being registered, for purposes of the transactions hereunder, under the
Securities Act of 1933, as amended (the "Securities Act") or any state
securities laws, and the shares are being delivered without registration in
reliance upon an exemption from the registration requirements of the Securities
Act or any state securities laws.  The Seller is acquiring the Sylvan Common
Stock hereunder only for its own account and not with any intention of making,
or with a view to, or for sale in connection with, any distribution thereof
within the meaning of the Securities Act unless such shares first are registered
under the Securities Act.

                                       8
<PAGE>
 
                In connection with the foregoing, the Seller and each of the
Stockholders hereby represen and warrant that:

                (a)   each has reviewed, discussed and evaluated the information
delivered under Section 10.1 B and has had the opportunity to ask questions of,
and receive answers from, executive officers of the Buyer concerning the terms
and conditions of this Agreement and to obtain any additional information which
such Stockholder considered necessary to verify the accuracy of the information
delivered under Section 10.1 B;

                (b)   each understands that it must bear the economic risks of
the investment in Sylvan Common Stock to be made hereunder for an indefinite
period of time because such stock has not been registered under the Securities
Act and, therefore, may not be sold until such stock subsequently is registered
under the Securities Act or an exemption from registration is available; and

                (c)   each has sufficient knowledge and experience in financial
and business matters to enable them to be capable of evaluating the merits and
the risks of the exchange of the Sylvan Common Stock for the business sold under
this Agreement and their prospective investment in the Buyer.

           B.   Legends.  It is understood and agreed that, to implement the
               -------                                                     
requirements of the Securities Act and state securities laws and evidence the
restrictions upon transfer contained in this Agreement, the Buyer will cause a
legend to be conspicuously noted on the certificates representing the Sylvan
Common Stock deliverable hereunder, and that the Buyer will issue stop transfer
instructions to its transfer agent, to the effect that such stock has not been
registered under the Securities Act and that no transfer may take place except
as permitted by Section 11 of this Agreement and after delivery of an opinion of
Buyer's counsel to the effect that registration thereof for the purpose of
transfer is not required under the Securities Act or that the stock proposed to
be transferred has been effectively registered for that purpose under the
Securities Act.

           C.   No Agreements with Respect to Purchaser Common Stock.  Neither
                ----------------------------------------------------          
Seller nor any of the Stockholders has entered into any agreement or
understanding with anyone for the sale, at Stockholder's or Seller's option or
otherwise, of any of the Sylvan Common Stock to be delivered hereunder to Seller
at the Closing.

11.  REGISTRATION RIGHTS:

     11.1  Registration Procedures and Expenses.  Buyer shall:
           ------------------------------------               

           (a)  as soon as practicable after the closing date but not later than
ninety (90) days after the closing date, prepare and file with the Securities
and Exchange Commission (the "Commission") a registration statement on Form S-3
which meets the requirements of Rule 415 promulgated under the Securities Act (a
"Shelf Registration Statement") covering the sale by the Seller from time to
time of the shares of the Sylvan Common Stock received by the Seller under this
Agreement. Buyer may extend its obligation to file a registration statement only
if Buyer advises Seller or the Stockholders that there is a pending, but
unannounced transaction or development which Sylvan determines is not then
appropriate for disclosure, and that registration of Seller's Sylvan Common
Stock would require such disclosure.

           (b)  use its best efforts, subject to receipt of necessary
information from the Seller, to cause each of the Shelf Registration Statements
to become effective;

                                       9
<PAGE>
 
           (c)  prepare and file with the Commission such amendments and
supplements to the Shelf Registration Statements and the prospectus used in
connection therewith as may be necessary to keep the Shelf Registration
Statements effective until the earlier of the date on which the Sylvan Common
Stock registered by such Shelf Registration Statement has been sold, or one year
from the date of the initial filing thereof;

           (d)  during the period referred to in (c) above, prepare and promptly
file with the Commission, and promptly notify the Seller of the filing of, such
amendment or supplement to each such Shelf Registration Statement and the
prospectus as may be necessary to correct any statements or omissions if, at any
time when a prospectus relating to the Sylvan Common Stock is required to be
delivered under the Securities Act, any event has occurred the result of which
is that any such prospectus then in effect would include or incorporate an
untrue statement of a material fact or omit to state any material fact necessary
to make the statements therein not misleading in light of the circumstances in
which they were made;

           (e)  advise the Seller, promptly after it shall receive notice or
obtain knowledge thereof, of the issuance of any stop order by the Commission
suspending the effectiveness of any of such Shelf Registration Statements or the
initiation or threatening of any proceeding for that purpose and promptly use
its diligent best efforts to prevent the issuance of any stop order and to
obtain its withdrawal if such stop order should be issued;

           (f)  furnish to the Seller with respect to the Sylvan Common Stock
registered under any of the Shelf Registration Statements such number of copies
of prospectuses and preliminary prospectuses in conformity with the requirements
of the Securities Act and such other documents as the Seller may reasonably
request (but in no event more than 100), in order to facilitate the public sale
or other disposition of all or any of the registered Sylvan Common Stock by the
Seller; provided, however, that the obligation of Buyer to deliver copies of
        --------  -------          
prospectuses or preliminary prospectuses to the Seller shall be subject to the
receipt by Buyer of reasonable assurances from the Seller that the Seller will
comply with the applicable provisions of the Securities Act and of such other
securities or blue sky laws as may be applicable in connection with any use of
such prospectuses or preliminary prospectuses;

           (g)  file documents required of Buyer for normal blue sky clearance
in states reasonably specified in writing by the Seller, provided, however, that
Buyer shall not be required to qualify to do business or consent to service of
process in any jurisdiction in which it is not now so qualified or has not so
consented; and

           (h)  bear all expenses in connection with the procedures in
paragraphs (a) through (g) of this Section 11.1 and the registration of the
Sylvan Common Stock pursuant to each of the Shelf Registration Statements, other
than fees and expenses, if any, of counsel or other advisers to the Seller.

     11.2  Engagement of Underwriters.  The parties hereto agree that the Buyer
           --------------------------                                          
shall have no obligation to (i) conduct, arrange or coordinate any distribution
or sales activities on behalf of the Seller with respect to the Sylvan Common
Stock other than as set forth in Section 11.1 above or (ii) retain any
underwriter(s) in connection with the registration and/or distribution of the
Sylvan Common Stock pursuant to this Section 11.  The Seller agrees that any
underwriter(s) or counsel engaged in connection with the registration or
distribution of the Sylvan Common Stock required to be registered pursuant to
this Section 11 will be retained by and at the sole expense of the Seller and
agrees further that any discounts or commissions payable to such underwriter(s)
shall also be an expense solely of the Seller.  In the event the Seller engages
one or more underwriters pursuant to this Section 11.2, the Seller shall enter
into an underwriting agreement with the managing or lead managing underwriter in
the form customarily used by such underwriter with such changes thereto as the
parties thereto shall agree; and, further, shall provide to such underwriter any
documents or other information as is necessary, in the underwriter's reasonable
opinion, to facilitate the effectiveness of the Shelf Registration Statement and
the completion of the distribution of the Sylvan Common Stock so registered.

           -------------------------------------------------------------        
hereby agrees to indemnify the Seller and each Stockholder against liability
arising out of or based upon any untrue statement or alleged untrue statement of
material fact in any of the Shelf Registration Statements filed by Buyer

                  Re:      Registration Statement on Form S-3
                           ----------------------------------

     Dear Sirs:

     We have acted as counsel to Sylvan Learning Systems, Inc., a Maryland
corporation (the "Company"), in connection with the Company's Registration
Statement on Form S-3 (the "Registration Statement") filed on the date hereof
with the Securities and Exchange Commission (the "Commission") under the
Securities Act of 1933, as amended (the "Act").  The Registration Statement
relates to 660,908 shares of the Company's Common Stock, par value $.01 per
share (the "Shares"), which were previously issued by the Company and are being
registered for resale by the holders thereof.

     In this capacity, we have examined the Company's Charter and By-Laws, the
proceedings of the Board of Directors of the Company relating to the issuance of
the Shares and such other documents, instruments and matters of law as we have
deemed necessary to the rendering of this opinion.  In such examination, we have
assumed the genuineness of all signatures, the authenticity of all documents
submitted to us as originals, and the conformity with originals of all documents
submitted to us as copies.

     Based upon the foregoing, we are of the opinion and advise you that each of
the Shares described in the Registration Statement has been duly authorized and
validly issued and is fully paid and nonassessable.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.  In giving our consent, we do not thereby admit that we
are in the category of persons whose consent is required under Section 7 of the
Act or the Rules and Regulations of the Commission thereunder.

                                    Very truly yours,
