                                                         As of February 23, 2000

The Purchasers named on the signature pages hereto


Ladies and Gentlemen:

         Sylvan Learning Systems, Inc., a Maryland corporation (the "Company"),
agrees with each of the purchasers named on the signature pages hereto (each, a
"Purchaser") as follows:

1.       PRELIMINARY MATTERS.

1.1      AUTHORIZATION OF DEBENTURES.

         The Company has authorized the issue and sale of $100,000,000 aggregate
principal amount of its 5% Convertible Subordinated Debentures due 2010 (the
"DEBENTURES"), such term to include any such Debentures issued in substitution
therefor pursuant to the terms of the Indenture. The Debentures shall be issued
pursuant to an Indenture substantially in the form set out in Exhibit 1. Certain
capitalized terms used in this Agreement are defined in Schedule A; references
to a "Schedule" or an "Exhibit" are, unless otherwise specified, to a Schedule
or an Exhibit attached to this Agreement.

1.2      ISSUE TAXES.

         The Company agrees to pay all taxes (other than taxes in the nature of
income, franchise or gift taxes) and governmental fees in connection with the
issuance, sale, delivery or transfer by the Company to the Purchasers of the
Debentures and the execution and delivery of this Agreement and the Other
Agreements and any modification of any of this Agreement or the Other Agreements
and will save each and all of the Purchasers harmless without limitation as to
time against any and all liabilities with respect to all such taxes and fees.
The obligations of the Company under this Section 1.2 are in addition to any
other obligations of the Company contained elsewhere in this Agreement and shall
survive the payment or prepayment of the Debentures, at maturity, upon
redemption or otherwise and the termination of this Agreement and the Other
Agreements.

1.3      DIRECT PAYMENT.

         Notwithstanding any provision to the contrary in the Indenture or the
Debentures, the Company will pay or cause to be paid all amounts payable with
respect to any Debenture held by the Purchasers (without any presentment of such
Debenture and without any notation of such payment being made thereon) by
crediting (before 12:00 Noon, New York time), by Federal funds bank wire
transfer in same day funds to such holder's account in any bank in the United
States of America as may be designated


                                       1


and specified in writing by such holder at least two Business Days prior
thereto. Each Purchaser's initial bank account for this purpose is on SCHEDULE
1.3 hereto.

1.4      REPLACEMENT DEBENTURES.

         If a mutilated Debenture that is a Transfer Restricted Security (as
defined in the Indenture) is surrendered to the Company or if a Purchaser or any
other institutional holder (or nominee thereof) of a Debenture that is a
Transfer Restricted Security claims and submits an affidavit or other evidence,
satisfactory to the Company, to the effect that the Debenture has been lost,
destroyed or wrongfully taken, the Company shall issue a replacement Debenture
without the need to post any bond, and no further indemnity shall be required as
a condition to the execution and delivery of a new Debenture other than the
unsecured written agreement of such owner reasonably satisfactory to the
Company, to indemnify the Company. With respect to any Debenture that is not a
Transfer Restricted Security which is surrendered to the Company or which is
claimed by the Purchaser or its holder to be lost, destroyed or wrongfully
taken, the Company may require the Purchaser or such holder to post a bond
against any loss arising in connection therewith as a condition to the execution
and delivery of a new Debenture and to indemnify the Company, in each case, to
the extent provided in the Indenture.

1.5      INDEMNIFICATION.

                  (a) In addition to all other sums due hereunder or provided
         for in this Agreement or any Other Agreement and any and all
         obligations of the Company to indemnify any Purchaser hereunder or
         under any Other Agreement, the Company hereby agrees, without
         limitation as to time, to indemnify each Purchaser, each Affiliate of
         each Purchaser and each director, officer, employee, counsel, agent or
         representative of each Purchaser and its Affiliates (collectively, the
         "INDEMNIFIED PARTIES") against, and hold it and them harmless from, to
         the fullest extent lawful, all losses, claims, damages, liabilities,
         costs (including, without limitation, costs of preparation and
         attorneys' fees and disbursements) and expenses, including expenses of
         investigation (collectively, "LOSSES"), incurred by it or them and
         arising out of or in connection with this Agreement or any Other
         Agreement, or the Transactions, regardless of whether the Transactions
         are consummated and regardless of whether any Indemnified Party is a
         formal party to any proceeding; PROVIDED, that the Company shall not be
         liable to any Indemnified Party for any Losses to the extent that it
         shall be finally determined by a court of competent jurisdiction (which
         determination is not subject to appeal or review) that such Losses
         arose from the gross negligence or willful misconduct of such
         Indemnified Party, which (i) is independent of any wrongful act by the
         Company, its Affiliates or any of its representatives and (ii) was not
         taken by such Indemnified Party in reliance upon any of the
         representations, warranties, covenants or promises of the Company
         herein or in the Other Agreements, including (without limitation) the
         certificates delivered by the Company pursuant hereto or thereto. The
         Company agrees to reimburse each Indemnified Party promptly for all
         such Losses as they are incurred by such Indemnified Party (regardless
         of whether it is or may be ultimately determined that such Indemnified
         Party is not entitled to indemnification hereunder), subject to
         repayment in the event that the Indemnified Party is ultimately
         determined not entitled to indemnification hereunder (as finally
         determined by a court of competent jurisdiction (which determination is
         not subject to review or appeal)). The obligations of the Company to
         each Indemnified Party hereunder shall be separate obligations, and the
         Company's liability to any such Indemnified Party hereunder shall not
         be extinguished solely because any other Indemnified Party is not
         entitled to indemnity hereunder. The obligations of each Indemnifying
         Party under this Section 1.5 shall survive the payment or prepayment of
         the Debentures, at maturity, upon acceleration, redemption or
         otherwise, the


                                       2


         redemption or repurchase of any Common Stock, any transfer of the
         Debentures or Common Stock by any Purchaser and the termination of this
         Agreement or any of the Other Agreements.

                  (b) In case any action, claim or proceeding shall be brought
         against any Indemnified Party with respect to which indemnity may be
         sought hereunder, such Indemnified Party shall promptly notify the
         Company in writing and the Company shall assume the defense thereof,
         including the employment of counsel reasonably satisfactory to such
         Indemnified Party and payment of all fees and expenses incurred in
         connection with the defense thereof; PROVIDED, that the failure to so
         notify the Company shall not affect any obligation it may have to any
         Indemnified Party under this Agreement or otherwise except to the
         extent that (as finally determined by a court of competent jurisdiction
         (which determination is not subject to review or appeal)) such failure
         materially and adversely prejudiced the Company. The Company shall not,
         without the Indemnified Party's prior written consent, consent to entry
         of any judgment or settle or compromise any pending or threatened
         claim, action or proceeding in respect of which indemnification or
         contribution may be sought hereunder unless the foregoing contains an
         unconditional release, in form and substance reasonably satisfactory to
         the Indemnified Parties, of the Indemnified Parties from all liability
         and obligation arising therefrom. Each Indemnified Party shall have the
         right to employ separate counsel in such action, claim or proceeding
         and participate in the defense thereof, but the fees and expenses of
         such counsel shall be at the expense of each Indemnified Party unless:
         (i) the Company has agreed to pay such expenses; or (ii) the Company
         has failed to promptly assume the defense and employ counsel reasonably
         satisfactory to such Indemnified Party; or (iii) the named parties to
         any such action, claim or proceeding (including any impleaded parties)
         include any Indemnified Party and the Company or an Affiliate of the
         Company, and such Indemnified Party shall have been advised by counsel
         that either (x) there may be one or more legal defenses available to it
         that are different from or in addition to those available to the
         Company or such Affiliate or (y) a conflict of interest may exist if
         such counsel represents such Indemnified Party and the Company or its
         Affiliate; PROVIDED that, if such Indemnified Party notifies the
         Company in writing that it elects to employ separate counsel in the
         circumstances described in clause (ii) or (iii) above, the Company
         shall not have the right to assume the defense thereof and such counsel
         shall be at the expense of the Indemnifying Parties.

                  Notwithstanding any other provision hereof the Company shall
         not (i) in connection with any one such action or proceeding, be
         responsible hereunder for the fees and expenses of more than one such
         firm of separate counsel (in addition to any local counsel), which
         counsel shall be designated by such Indemnified Party, (ii) be liable
         for any settlement of any such action effected without its written
         consent (which shall not be unreasonably withheld or delayed), or (iii)
         be responsible hereunder for attorneys' fees or expenses incurred by
         the Indemnified Parties in excess of $500,000 in the aggregate other
         than 50% of such attorneys' fees and expenses in excess of $1,000,000.

                  (c) If the indemnification provided for in this Section 1.5 is
         unavailable to, or insufficient to hold harmless, any Indemnified Party
         in respect of any Losses referred to herein, then the Company shall
         contribute to the amount paid or payable by such Persons as a result of
         such Losses in such proportion as is appropriate to reflect the
         relative fault of the Company, its subsidiaries and Affiliates, on the
         one hand, and such Indemnified Party, on the other hand, in connection
         with the actions which resulted in such Losses, as well as any other
         relevant equitable considerations. The amount paid or payable by any
         such Person as a result of the Losses referred to above shall be deemed
         to include any legal or other fees or expenses reasonably incurred by
         such Person in connection with any investigation, lawsuit or legal or
         administrative action or proceeding.

                  (d) The parties hereto agree that it would not be just and
         equitable if contribution pursuant to this Section 1.5 were determined
         by pro rata allocation or by any other method of


                                       3


         allocation which does not take account of the equitable considerations
         referred to in the immediately preceding paragraph. No Person guilty of
         fraudulent misrepresentation (within the meaning of Section 11(f) of
         the Securities Act) shall be entitled to contribution from any Person
         who is not guilty of such fraudulent misrepresentation.

2.       SALE AND PURCHASE OF DEBENTURES.

         Subject to the terms and conditions of this Agreement, the Company will
issue and sell to each Purchaser, and each Purchaser will severally purchase
from the Company, at the Closing, Debentures in the respective amounts as set
forth in Schedule 2 at a purchase price of 100% of the principal amount thereof.
In connection with the Transactions, the Company shall pay to the Persons
designated by Apollo Management IV, L.P. ("APOLLO MANAGEMENT") a closing fee
equal to 1% of the aggregate principal amount of Debentures purchased by the
Purchasers (the "CLOSING FEE").

3.       CLOSING.

         The sale and purchase of the Debentures shall occur at the offices of
Venable, Baetjer and Howard, LLP, 1800 Mercantile Bank and Trust Building, 2
Hopkins Plaza, Baltimore, Maryland 21201, at 9:00 a.m., local time, at a closing
(the "CLOSING"), which shall occur as soon as practicable after satisfaction or
waiver of each of the conditions to closing set forth herein (but in no event
prior to March 20, 2000) or on such other Business Day thereafter as may be
agreed upon by the Company and Apollo Management. The date on which the Closing
occurs is referred to herein as the "CLOSING DATE." At the Closing (a) the
Company will deliver to each Purchaser the Debentures to be purchased by such
Purchaser in the form of a single Debenture (or such greater number of
Debentures as Apollo Management may request), dated the Closing Date, and
registered in such Purchaser's name (or in the name of such Purchaser's
nominee), against delivery by such Purchaser to the Company of immediately
available funds in the amount of the purchase price therefor by wire transfer to
such bank account as the Company shall have notified Apollo Management in
writing and (b) the Company shall pay the Closing Fee in immediately available
funds by wire transfer to such bank accounts as Apollo Management shall have
notified the Company in writing. If at the Closing the Company shall fail to
tender such Debentures to such Purchaser or pay the Closing Fee as provided
above in this Section 3, or any of the conditions specified in Section 4 shall
not have been fulfilled to such Purchaser's reasonable satisfaction, such
Purchaser shall, at its election, be relieved of all further obligations under
this Agreement, without thereby waiving any rights it may have by reason of such
failure or such nonfulfillment.

4.       CONDITIONS TO CLOSING.

         Each Purchaser's obligation to purchase and pay for the Debentures to
be sold to such Purchaser at the Closing is subject to the fulfillment or
waiver, prior to or at the Closing, of the following conditions:

4.1      REPRESENTATIONS AND WARRANTIES.

         proceeding at law or in equity).

                  (b) Each of the Other Agreements has been duly authorized by
         the Company and, on the Closing Date, will have been validly executed
         and delivered by the Company. When each Other Agreement has been duly

         Common Stock, or other ownership interests, issuable or reserved for
         issuance upon exercise of subscriptions, rights, warrants, options,
         calls, convertible securities, commitments of sale or Liens related to
         or entitling any person to purchase or otherwise to acquire any shares
         of the capital stock of the Company (and the exercise price thereof).

         legal entity duly organized, validly existing and in good standing

         and is in good standing in each jurisdiction in which such
         qualification is required by law, other than those jurisdictions as to

         individually or in the aggregate, reasonably be expected to have a
         Material Adverse Effect. Each such Subsidiary has the power and
         authority to own or hold under lease the properties it purports to own
         or hold under lease and to transact the business it transacts and
         proposes to transact.

                  (a) The Company has filed all required forms, reports and
         documents with the SEC since January 1, 1995 (the "SEC DOCUMENTS"),
         each of which complied in all material respects with all of the
         requirements of the Securities Act or the Exchange Act, as applicable,
         and did not contain any untrue statement of a material fact or omit to
         state any material fact required to be contained therein or necessary

         adjustments).

                  (b) The Company's unaudited financial statements attached as
         Schedule 5.5(b), were prepared on the same basis as the financial
         statements contained in the SEC Documents and fairly present the
         consolidated financial position of the Company and its Subsidiaries as

         operations and cash flow for the respective periods, and have been
         prepared in accordance with GAAP consistently applied throughout the
         periods involved, except such statements do not contain footnotes or
         related schedules. Since December 31, 1999, there has been no material
         adverse change in the business, operations, properties, prospects or
         condition (financial or otherwise) of the Company or any of its
         Subsidiaries. Since December 31, 1999, the Company has conducted its
         business in the usual, regular and ordinary course.

                  (c) The Company's budget for 2000 attached as Schedule 5.5(c)
         was prepared in good faith based on assumptions and projections
         believed to have been reasonable at the time made and were prepared in
         all material respects consistent with past accounting practices.

Adverse Effect.

         Company or any Subsidiary or any property of the Company or any
         Subsidiary before or by any Governmental Authority that, individually

         all Environmental Laws, except where such non-compliance could not,
         singly or in the aggregate, reasonably be expected to have a Material

         received any notice that alleges that the Company or its Subsidiaries
         is not in compliance with any Environmental Laws, and to the best of
         the Company's knowledge, there are no circumstances that may prevent or
         interfere with such compliance in the future.


                                       9


                  (b) There is no Environmental Claim pending or threatened, to

         Environmental Claim the Company or its Subsidiaries has retained or
         assumed either contractually or by operation of law, and to the best of

         benefits) pending or to the knowledge of the Company threatened with
         respect to any Plan, the assets of any trust thereunder, or the Plan
         sponsor or the Plan administrator with respect to the design or
         operation of any Plan. Each Plan which is intended to be "qualified"
         within the meaning of section 401(a) of the Code has received a
         favorable determination letter from the Internal Revenue Service with
         respect to its tax-qualified status and to the knowledge of the
         Company, nothing has occurred since the date of the most recent
         applicable determination letter that would adversely affect the
         tax-qualified status of any such Plan;

                  (d) The consummation of the Transactions will not, either

         Affiliate, the Company has operated and administered each Plan in
         substantial compliance with all applicable Laws.

                  (f) None of the Company, any of its Subsidiaries, any ERISA
         Affiliate, any of the ERISA Plans, any trust created thereunder, nor to
         the Company's knowledge, any trustee or administrator thereof has

shall not prohibit the Company or any other holder of Debentures from contesting
any such reproduction to the same extent that it could contest the original, or
from introducing evidence to demonstrate the inaccuracy of any such
reproduction.

12.      SUBSTITUTION OF PURCHASER.

         Each Purchaser shall have the right to substitute any designee
reasonably acceptable to the Company as the purchaser of the Debentures that
such Purchaser has agreed to purchase hereunder, by written notice to the
Company. Any affiliate of a Purchaser shall be deemed acceptable to the Company.
Upon receipt of such notice, wherever the word "Purchaser" is used in this
Agreement (other than in this Section 12), such word shall be deemed to refer to
such designee in lieu of such Purchaser.

13.      MISCELLANEOUS.

13.1     SUCCESSORS AND ASSIGNS.

         All covenants and other agreements contained in this Agreement by or on
behalf of any of the parties hereto bind and inure to the benefit of their
respective successors and assigns (including, without limitation, any permitted
subsequent holder of a Debenture) whether so expressed or not.

13.2     SEVERABILITY.

         Any provision of this Agreement that is prohibited or unenforceable in
any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall (to the full extent permitted by law) not invalidate or
render unenforceable such provision in any other jurisdiction.

13.3     CONSTRUCTION.

         Each covenant contained herein shall be construed (absent express
provision to the contrary) as being independent of each other covenant contained
herein, so that compliance with any one covenant shall not (absent such an
express contrary provision) be deemed to excuse compliance with any other
covenant. Where any provision herein refers to action to be taken by any Person,
or which such Person is prohibited from taking, such provision shall be
applicable whether such action is taken directly or indirectly by such Person.

13.4     COUNTERPARTS.

which shall be an original but all of which together shall constitute one
instrument. Each counterpart may consist of a number of copies hereof, each
signed by less than all, but together signed by all, of the parties hereto.

13.5     GOVERNING LAW; SUBMISSION TO JURISDICTION;.

         THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF MARYLAND, WITHOUT REGARD TO THE CONFLICT OF LAW RULES
THEREOF. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY SUBMITS TO THE
JURISDICTION OF ANY MARYLAND STATE COURT SITTING IN THE CITY OF BALTIMORE OR ANY

OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY
SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT AND ANY CLAIM THAT ANY
SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN
INCONVENIENT FORUM.

13.6     CONFIDENTIALITY.

         The terms of this Agreement shall remain confidential until all parties
to this Agreement agree in writing to the extent and form of disclosure.
