shall be contributed to New AB as additional capital.

          (b) Operations in the Ordinary Course.  Each of ABC and New AB
              ---------------------------------                        
covenants and agrees that, except as otherwise provided in this Distribution
Agreement or any Ancillary Agreement, during the period from the date of this

               (ii) ABC shall pay or cause to be paid, or otherwise provide for

     relating to the Transferred Business as to which ABC is a direct obligor,
     if any.

     2.3  Assumption and Satisfaction of Liabilities.  Except as otherwise
          ------------------------------------------                     
specifically set forth in any Ancillary Agreement, at all times from and after
the Distribution Date, New AB shall, and shall cause any and all successors and
assigns to assume, pay, perform and discharge all liabilities relating to the
Transferred Business as and when due.

     2.4  Further Assurances.
          ------------------

          (a) In case at any time after the Distribution Date any further action
is reasonably necessary or desirable to carry out the purposes of this
Distribution Agreement and the Ancillary Agreements, the proper officers of each
party to this Distribution Agreement shall take all such action.  Without
limiting the foregoing, ABC and New AB shall use their commercially reasonable
efforts to obtain all required consents and approvals of third parties, to enter
into all amendatory agreements and to make all filings and applications that may
be required for the consummation of the transactions contemplated by this
Distribution Agreement and the Ancillary Agreements.

          (b) In the event that after the Distribution Date, ABC shall (i)
receive notice from New AB that certain assets or liabilities which properly
relate to the Transferred Business were not transferred to New AB on or before
the Distribution Date, or (ii) determine that certain assets or liabilities of
ABC that constitute assets or liabilities that do not properly relate to the
Transferred Business were transferred in error to New AB on the Distribution
Date, then as promptly as practical thereafter ABC shall transfer and assign
such assets or liabilities to New AB or New AB shall transfer and assign such
assets or liabilities to ABC, as the case may be, without, in any case, the
payment by either party of any consideration therefor.

                                       4
<PAGE>

          (c) Nothing in this Distribution Agreement shall be deemed to require
the transfer of any assets or the assumption of any liabilities which by their
terms or operation of law cannot be transferred; provided, however, that the
parties hereto shall cooperate to seek to obtain any necessary consents or
approvals for the transfer of all assets and liabilities contemplated to be
transferred pursuant to this Distribution Agreement.  In the event that any such
transfer of assets or liabilities has not been consummated as of the
Distribution Date, from and after the Distribution Date the party retaining such
asset shall hold such asset in trust for the use and benefit of the party
entitled thereto (at the expense of the party entitled thereto, with the party
retaining such asset to be promptly reimbursed all reasonable expenses incurred
in holding such asset) or retain such liability for the account of the party by
whom such liability is to be assumed pursuant hereto, as the case may be (at the
expense of the party by which such liability is to be assessed, with the party
retaining such liability to be promptly reimbursed all reasonable expenses
incurred in retaining such liability), and take such other action as may be
reasonably requested by the party to whom such asset is to be transferred, or by
whom such liability is to be assumed, as the case may be, in order to place such
party, insofar as is reasonably possible, in the same position as would have
existed has such asset or liability been transferred as contemplated hereby.  As
and when any such asset or liability becomes transferable, such transfer shall
be effected forthwith.  As of the Distribution Date, each party hereto shall be
deemed to have acquired complete and sole beneficial ownership over all of the
assets held by it, together with all rights, powers and privileges incident
thereto, and shall be deemed to have assumed in accordance with the terms of
this Distribution Agreement all of the liabilities, and all duties, obligations
and responsibilities incident thereto, which such party is entitled to acquire
or required to assume pursuant to the terms of this Distribution Agreement.

     2.5  No Representations or Warranties.  Each of the parties hereto
          --------------------------------                            
understands and agrees that no party hereto is in this Distribution Agreement or
in any other agreement or document contemplated by this Distribution Agreement
or otherwise, making any representation or warranty whatsoever, including,
without limitation, as to title, value or legal sufficiency.  It is also agreed
and understood that all assets either transferred to or retained by the parties,
as the case may be, shall be "as is, where is" and that the party to which such
assets are to be transferred hereunder shall (subject to Section 2.3) bear
economic and legal risk that any conveyances of such assets shall prove to be
insufficient or that such party's title to any such assets shall be other than
good and marketable and free from encumbrances.

     2.6  Guarantees.  Except as may be specified in any Ancillary Agreement,
          ----------                                                        
each of ABC and New AB shall use is best reasonable effort to have, on the
Distribution Date, or as soon as practicable thereafter, ABC removed as
guarantor of or obligor for any liabilities relating to the Transferred
Business.

     2.7  Certain Post-Distribution Transactions.  Each of ABC and New AB shall
          --------------------------------------                              
comply and otherwise not take any action inconsistent with each representation,
covenant and statement made, or to be made, to tax counsel in connection with
such counsel's rendering of an opinion as to certain tax aspects of the
Distribution.

     2.8  Ancillary Agreements.  Effective as of the Distribution Date, each of
          --------------------                                                
ABC and New AB shall enter into the Ancillary Agreements and any other
agreements in respect of the Distribution reasonably necessary or appropriate in
connection with the transactions contemplated thereby and hereby.

          ------------------------------------------                           
(an "Indemnifying Party") is or may be required to pay to any other person (an

reduced (retroactively or prospectively) by an insurance proceeds or other

related Indemnifiable Loss.  Notwithstanding anything herein to the contrary,
indemnification relating to any arrangements between ABC and New AB for the

shall be governed by the terms of such arrangements and not by this Article or
as otherwise set forth in this Distribution Agreement and the Ancillary
Agreements.

     4.5  Procedures for Indemnification.
          ------------------------------

          (a) If a claim or demand is made against an Indemniteee by any person
who is not a party to this Distribution Agreement (a "Third Party Claim") as to
which such Indemnitee is entitled to indemnification pursuant to this
Distribution Agreement, such Indemnitee shall notify the Indemnifying Party in
writing and in reasonable detail of the Third Party Claim promptly (and in any
event within 20 business days) after receipt by such Indemnitee of written
notice of the

                                       6
<PAGE>

Third Party Claim. Thereafter, the Indemnitee shall deliver to the Indemnifying
Party, promptly (and in any event within 20 business days) after Indemnitee's
receipt thereof, copies of all notices and documents received by the Indemnitee
relating to the Third Party Claim.

          (b) If a Third Party Claim is made against an Indemnitee, the
Indemnifying Party shall be entitled to participate in the defense thereof and,
if it so chooses and acknowledges in writing its obligation to indemnify the
Indemnitee therefor, to assume the defense thereof with counsel selected by the
Indemnifying Party.  Should the Indemnifying Party so elect to assume the
defense of a Third Party Claim the Indemnifying Party shall not be liable to the
Indemnitee for legal or other expenses subsequently incurred by the Indemnitee
in connection with the defense thereof.

          (c) If the Indemnifying Party acknowledges in writing liability for
indemnification of a Third Party Claim, then in no event will the Indemnitee
admit any liability with respect to, or settle, compromise or discharge, any
Third Party Claim without the Indemnifying Party's prior written consent.

     4.6  Indemnification Payments.  Indemnification required by this Article IV
          ------------------------

the investigation or defense, as and when bills are received or loss, liability,
claim, damage or expense is incurred.

     4.7  Other Adjustments.  The amount of any indemnification payments shall
          -----------------                                                  
be (i) increased to take into account any net tax cost actually incurred by the
Indemnitee arising from any payments received from the Indemnifying Party
(grossed up for such increase), and (ii) reduced to take account of any tax
benefit or recovery of insurance proceeds actually realized by the Indemnitee
arising from the such indemnification payment.  In computing the amount of such
tax cost or tax benefit, the Indemnitee shall be deemed to recognize all other
items of income, gain, loss, deduction or credit before recognizing any item
arising from the receipt of any payment with respect to any indemnification
payments pursuant to this Distribution Agreement.  In addition, if the amount of
any losses subject to indemnification under this Distribution Agreement, at any
time after payment of such indemnification, be reduced by recovery, settlement
or otherwise, the amount of such reduction, less any expenses incurred in
connection therewith, shall promptly be repaid by the Indemnitee to the
Indemnifying Party, up to the aggregate amount of any payments received from
such Indemnifying Party pursuant to this Distribution Agreement with respect to
such losses.

     4.8  Survival of Indemnities.  The rights and obligations of each of ABC
          -----------------------

                                    --------

     A.  ABC and New AB have entered into a Distribution Agreement dated as of
October 31, 1997 (the "Distribution Agreement"), providing for the contribution

     B.  Following the Contribution, subject to the conditions set forth in the
Distribution Agreement, all issued and outstanding shares of capital stock of
New AB will be distributed (the "Distribution") to the Sole Stockholder.

     C.  During the Transition Period, ABC desires to provide, and New AB
desires to receive, certain management and other corporate services from ABC, as
hereinafter specifically provided (collectively, the "Management Services" and,
individually, a "Management Service"), and the parties desire to set forth
herein the basis on which the Management Services shall be provided to New AB.

     The parties agree as follows:

     1.  Definitions.  Unless the context otherwise requires, capitalized
         -----------
terms not otherwise defined herein shall have the respective meanings given to
them in the Distribution Agreement.

     2.  Management Services.  The specific Management Services to be provided
         -------------------  
by ABC to New AB are comprised of the services more particularly set forth on
Attachment 1 hereto.  Subject to the terms of this Agreement, upon the written
request setting forth additional or amended Management Services to be provided
to New AB made by an Executive Vice President of New AB or a person designated
to act on his behalf in an instrument executed by such New AB Executive Vice
President and delivered to ABC, ABC shall provide each of such additional or
amended Management Services with respect to the Transferred Business in the
manner and to the same general extent as such Management Services have been
provided by ABC in connection with the Transferred Business before the
Contribution.

     3.  Term.  Except with respect to Section 12, the term of this Agreement
         ----
shall commence on the date hereof and terminate (a) at the end of the Transition
Period or (b) on such other date as the parties hereto shall mutually agree in
writing to terminate this Agreement (the "Term").  Services shall be provided

parties.  In addition, New AB shall have the right to terminate a Management
Service or Management Services upon sixty (60) days prior written notice to ABC.
Termination of one or more Management Services by New AB shall not affect the
obligation of ABC to furnish all other Management Services for the remainder of
the Term.

authorized officer of ABC and New AB, the Management Services shall be provided

on Attachment 1.

     5.  Delegation.  ABC may retain the services of such third parties,

necessary or appropriate to facilitate the expeditious discharge of ABC's
responsibilities hereunder.

     6.  Independence.  All employees and representatives of ABC providing
         ------------
Management Services to New AB will be deemed for purposes of all compensation
and employee benefits to be employees or representatives of ABC and not
employees or representatives of New AB. In performing such Management Services,
such employees or representatives will be under the direction, control and
supervision of ABC (and not New AB) and ABC will have the sole right to exercise
all authority with respect to the employment (including termination of
employment), assignment and compensation of such employees and representatives.
ABC shall be solely responsible for the payment of all payroll and withholding
taxes relating to its employees for services provided to New AB during the Term.

     7.  Impracticability.  ABC shall not be required to provide any Management
         ----------------                                                     
Service to the extent the performance or the provision of such Management
Service becomes impracticable as a result of a cause or causes outside of the
reasonable control of ABC, or to the extent the performance of such Management
Service would require ABC to violate applicable laws, rules or regulations or
result in the breach of any license, permit or applicable contract.

     8.  Additional Resources.  In providing the Management Services, ABC
         --------------------
shall not be obligated to:  (i) hire any additional employees, (ii) maintain the
employment of any specific employee, or (iii) purchase, lease or license any
additional equipment or software.

     9.  Force Majeure.  The obligations of ABC under this Agreement are
         -------------
subject to conditions of force majeure, including an act of God, strike or
walkout or other labor dispute, act of a public enemy, war, revolution, riot,
fire, storm, flood, earthquake, embargo and any other cause which is not
reasonably within the control of the party affected thereby.

     10.  Nondisclosure.  In the event that, during the Term and in connection
          ------------- 
with a party's performance of its obligations hereunder, either party shall
receive information concerning the other party hereto which the receiving party
knows, or has reason to believe, is confidential or proprietary to the party to
whom such information relates, the party receiving such information shall take
all reasonable steps to (a) protect and hold such information in confidence and
prevent its disclosure to third parties unless such third parties are under a
duty of confidentiality to the party to which such information relates; and (b)
restrict its use to those purposes consent to in writing by the party to whom
such information relates; provided, however, that the party receiving such
information shall not be required to protect or hold in confidence any
information or data which (i) is or becomes available to the public without the
fault of the receiving party, (ii) is independently developed by the receiving
party, (iii) is disclosed to the receiving party by a third party known to the
receiving party not to be under any duty of confidentiality to the party to whom
such information relates with respect to such information or (iv) except as may
otherwise be required by law. This Section 10 shall not limit the obligation of
the parties under the Distribution Agreement to provide access to records after
the date hereof.

Agreement are consummated, unless specifically provided otherwise in this
Agreement (including all Schedules hereto), each party shall bear and pay all

party may waive compliance by any other party with any term or provision of this
Agreement that such other party was or is obligated to comply with or perform,
provided, however, that such waiver shall not operate as a waiver of, or
estoppel with respect to, any other or subsequent failure. No failure to
exercise and no delay in exercising any right, remedy, or power hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right, remedy, or power hereunder preclude any other or further exercise thereof
or the exercise of any other right remedy, or power provided herein or by law or
in equity. The waiver by any party of the time for performance of any act or
condition hereunder does not constitute a waiver of the act or condition itself.

          --------
Agreement are consummated, unless specifically provided otherwise in this
Agreement (including all Schedules hereto), each party shall bear and pay all

                           VENDOR CONTRACTS AGREEMENT

     THIS VENDOR CONTRACTS AGREEMENT, dated as of October 31, 1997 (the
"Agreement"), is made by and between THE ADVISORY BOARD COMPANY, a Maryland
corporation ("ABC") and THE CORPORATE ADVISORY BOARD COMPANY, a Delaware
corporation ("New AB").

                                    RECITALS
                                    --------

     A.  ABC and New AB have entered into a Distribution Agreement dated as of
October 31, 1997 (the "Distribution Agreement"), providing for the contribution
by ABC of the Transferred Business (as defined therein) to New AB.

     B.  Following the Contribution, subject to the conditions set forth in the
Distribution Agreement, all issued and outstanding shares of capital stock of
New AB will be distributed (the "Distribution") to the Sole Stockholder.

     C.  In the interest of an orderly transition with respect to the transfer
of the Transferred Business to New AB and certain third-party vendor contracts
relating thereto (the "Vendor Contracts"), the parties desire to provide for (i)
the provision during the Transition Period of services pursuant to the Vendor
Contracts (the "Vendor Services") to New AB or ABC as appropriate and (ii) the
appropriate allocation of related costs and expenses relating to such Vendor
Services.

     The parties agree as follows:

     1.  Definitions.  Unless the context otherwise requires, capitalized terms
         -----------
not otherwise defined herein shall have the respective meanings given to them in
the Distribution Agreement.

     2.  Vendor Services.
         ---------------

         (a) The Vendor Contracts are set forth on Attachment 1 hereto. Subject
to the terms of this Agreement, upon the written request setting forth
additional or amended Vendor Services to be provided to New AB made by an
Executive Vice President of New AB or a person designated to act on his behalf
in an instrument executed by such New AB Executive Vice President and delivered
to ABC, ABC shall provide, or cause provision, to New AB of each of the Vendor
Services with respect to the Transferred Business in the manner and to the same
general extent as such Vendor Services have been provided to ABC in connection
with the Transferred Business before the Contribution.

         (b) Costs and expenses relating to Vendor Contracts shall be allocated
as shall be determined by the parties as follows or as otherwise shall be
mutually agreed in writing by the parties:

                (i) Segregate Vendor Contract Invoices:  If invoices relating to
          Vendor Services can be divided to reflect properly the Vendor Services
          provided to ABC and New AB, respectively, such invoices shall be
          segregated and paid directly by the appropriate party to whom the
          related Vendor Services were provided.

                (ii) Reimburse ABC: In the event that invoices relating to
          Vendor Services cannot be segregated and paid as described in
          subparagraph (i) above, New AB shall pay its allocated share directly
          or reimburse ABC for Vendor Services provided to New AB pursuant to
          this Agreement as set forth in Attachment 1.

                                      D-1

     3.  Term.  Except with respect to Section 6, the term of this Agreement
         ----
shall commence on the date hereof and terminate (a) at the end of the Transition
Period or (b) such other date as the parties hereto shall mutually agree in
writing to terminate this Agreement (the "Term").  New AB shall have the right
to terminate a Vendor Service or Vendor Services upon sixty (60) days prior
written notice to ABC.  Termination of one or more Vendor Services by New AB
shall not affect the obligation of ABC to furnish all other Services for the
remainder of the Term.

     4.  Nondisclosure.  In the event that, during the Term and in connection
         -------------
with a party's performance of its obligations hereunder, either party shall
receive information concerning the other party hereto which the receiving party
knows, or has reason to believe, is confidential or proprietary to the party to
whom such information relates, the party receiving such information shall take
all reasonable steps to (a) protect and hold such information in confidence and
prevent its disclosure to third parties unless such third parties are under a
duty of confidentiality to the party to which such information relates; and (b)
restrict its use to those purposes consent to in writing by the party to whom
such information relates; provided, however, that the party receiving such
information shall not be required to protect or hold in confidence any
information or data which (i) is or becomes available to the public without the
fault of the receiving party, (ii) is independently developed by the receiving
party, (iii) is disclosed to the receiving party by a third party known to the
receiving party not to be under any duty of confidentiality to the party to whom
such information relates with respect to such information or (iv) except as may
otherwise be required by law. This Section 4 shall not limit the obligation of
the parties under the Distribution Agreement to provide access to records after
the date hereof.

     5.  Limitation on Liability.  ABC's liability to New AB in connection
         -----------------------
with this Agreement and the Vendor Services to be provided by ABC shall be
limited to actual damages arising from ABC's gross negligence or willful
misconduct in the performance of its duties and responsibilities hereunder;
provided, however, that, in no event shall ABC be liable for any incidental or
consequential damages.

     6.  Indemnity.
         ---------

         (a) ABC agrees to defend, indemnify and hold New AB and its officers,
directors, employees and agents harmless from and against all liabilities,
losses, claims, damages and expenses of any nature, including reasonable
attorneys' fees, that are reasonably incurred by New AB arising out of the
performance of the Services hereunder, except where such liability, loss, claim,
damage or expense shall have been caused by New AB's gross negligence or willful
misconduct in the performance of its duties and responsibilities hereunder.

         (b) New AB agrees to defend, indemnify and hold ABC and its officers,
directors, employees and agents harmless from and against all liabilities,
losses, claims, damages and expenses of any nature, including reasonable
attorneys' fees, that are reasonably incurred by ABC arising out of the
performance of the Services hereunder, except where such liability, loss, claim,

                                      D-2
<PAGE>

damage or expense shall have been caused by ABC's gross negligence or willful
misconduct in the performance of its duties and responsibilities hereunder.

     7.  Mutual Cooperation.  ABC and New AB will provide each other with
         ------------------
information and assistance reasonably necessary to investigate, defend or
prosecute any claims, suits, charges, including but not limited to equal
employment opportunity, workers compensation, insurance and similar claims
brought by or against ABC or New AB relating to either of their businesses. This
provision shall survive termination of this Agreement.

     8.  Third Party Rights.  Nothing in this Agreement, express or implied, is
         ------------------                                                   
intended to confer upon any person (including, without limitation, employees),
other than the parties hereto and their respective successors and assigns, any
rights or remedies of any nature whatsoever under or by reason of this
Agreement.

     9.  Relationship of Parties.  Nothing in this Agreement shall be deemed or
         -----------------------                                              
construed by the parties or any third party as creating the relationship of
principal and agent, partnership or joint venture between the parties, it being
understood and agreed that no provision contained herein, and no act of the
parties, shall be deemed to create any relationship between the parties other
than the relationship of independent contractor nor be deemed to vest any
rights, interest or claims in any third parties.

     10.  Successor and Assigns.  This Agreement shall inure to the benefit of
          ---------------------  
and be binding upon the respective successors and assigns of the parties hereto,
provided that this Agreement may not be assigned by either of the parties hereto
without the prior written consent of the other.

     11.  Notices.  All notices and other communications required or permitted

been duly given if delivered by hand or mailed, postage prepaid or by certified
or registered mail, and addressed to the applicable party at the respective
addresses set forth in the Distribution Agreement (or at such other address for
a party as shall be specified by a like notice).

     12.  Governing Law.  The validity, enforceability and performance of this
          -------------                                                      
Agreement shall be governed by and construed in accordance with the laws of the
State of Maryland (excluding its choice of law rules).

     13.  Entire Agreement.  The parties intend that the terms of this
          ----------------
Agreement, including the attached schedules, shall be the final expression of
their agreement with respect to the subject matter hereof and may not be
contradicted by evidence of any prior or contemporaneous agreement. The parties
further intend that this Agreement shall constitute the complete and exclusive
statement of its terms and that no extrinsic evidence whatsoever may be
introduced in any judicial, administrative or other legal proceedings involving
this Agreement.

     14.  Counterparts.  This Agreement may be executed in counterparts, each of
          ------------                                                         
which shall be deemed an original, but all of which taken together shall
constitute one and the same instrument.

upon the written consent of all of the parties. By an instrument in writing, any
party may waive compliance by any other party with any term or provision of this
Agreement that such other party was or is obligated to comply with or perform,
provided, however, that such waiver shall not operate as a waiver of, or
estoppel with respect to, any other or subsequent failure. No failure to
exercise and no delay in exercising any right, remedy, or power hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right, remedy, or power hereunder preclude any other or further exercise thereof
or the exercise of any other right remedy, or power provided herein or by law or
in equity. The waiver by any party of the time for performance of any act or
condition hereunder does not constitute a waiver of the act or condition itself.

     17.  Expenses.  Whether or not the transactions contemplated in this
          --------
Agreement are consummated, unless specifically provided otherwise in this
Agreement (including all Schedules hereto), each party shall bear and pay all

thereof to any person, place or circumstance, shall be held by a court of
competent jurisdiction to be void, invalid or unenforceable, the remainder of
this Agreement and such provisions as applied to other persons, places or
circumstances shall remain in full force and effect.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed by their duly authorized officers as of the date first above written.
