                  AGREEMENT  AND PLAN OF MERGER,  dated as of December  21, 1999
(the "Agreement") among AMERICA ONLINE, INC., a Delaware corporation ("Parent"),
MQ ACQUISITION,  INC., a Delaware  corporation and a wholly owned  subsidiary of
Parent  ("Merger  Sub"),  and  ANATOLIA,   INC.,  a  Delaware  corporation  (the
"Company").

                  WHEREAS, the Boards of Directors of Parent, Merger Sub and the
Company  have  each  determined  that  it is in  the  best  interests  of  their
respective  Stockholders  for Parent to acquire the  Company  upon the terms and
subject to the conditions set forth herein;

                  WHEREAS,  in  furtherance of such  acquisition,  the Boards of
Directors of Parent,  Merger Sub and the Company  have each  approved the merger
(the "Merger") of Merger Sub with and into the Company,  in accordance  with the
General Corporation Law of the State of Delaware (the "DGCL") and subject to the
conditions  set forth  herein,  which Merger will result in, among other things,
the Company becoming a wholly owned subsidiary of Parent;

                  WHEREAS,  as  a  condition  to  the  willingness  of,  and  an
inducement   to,   Parent  and   Merger  Sub  to  enter  into  this   Agreement,
contemporaneously  with the  execution and delivery of this  Agreement,  certain
holders of Company  Common  Stock (as  defined  herein),  are  entering  into an
agreement dated as of the date hereof (the "Stockholders Agreement") in the form
of Exhibit A attached  hereto,  providing  for certain  actions  relating to the
transactions contemplated by this Agreement;

                  WHEREAS,  as  a  condition  to  the  willingness  of,  and  an
inducement   to,   Parent  and   Merger  Sub  to  enter  into  this   Agreement,
contemporaneously with the execution and delivery of this Agreement, the Company
is  entering  into a Stock  Option  Agreement  dated as of the date  hereof (the
"Option Agreement") in the form of Exhibit B attached hereto, granting Parent an
irrevocable  option to purchase  up to that  number of shares of Company  Common
Stock as shall represent 10% (by voting power) of the total outstanding  Company
Common Stock, on the terms and subject to the conditions set forth therein;

                  WHEREAS, for federal income tax purposes,  it is intended that
the Merger  shall  qualify as a tax-free  reorganization  within the  meaning of
Section  368(a) of the Internal  Revenue Code of 1986,  as amended (the "Code");
and

                  WHEREAS,  for  accounting  purposes,  it is intended  that the
Merger shall qualify for "pooling-of-interests" treatment.

                  NOW,  THEREFORE,  in  consideration  of the  foregoing and the
mutual representations,  warranties,  covenants and agreements herein contained,
and  intending to be legally bound  hereby,  Parent,  Merger Sub and the Company
hereby agree as follows:


                                       1





                                    ARTICLE I

                                   THE MERGER

                  1.1  The Merger.  At the Effective Time (as defined in Section
1.2) and subject to and upon the terms and  conditions of this Agreement and the
DGCL, (a) Merger Sub shall be merged with and into the Company, (b) the separate
corporate existence of Merger Sub shall cease, and (c) the Company shall, as the
surviving  corporation in the Merger,  continue its existence under Delaware law
as a wholly owned subsidiary of Parent. The Company as the surviving corporation
after  the  Merger  is  hereinafter  sometimes  referred  to as  the  "Surviving
Corporation."

                  1.2  Effective Time.  As promptly  as  practicable  after  the
satisfaction or, to the extent permitted hereunder, waiver of the conditions set
forth in Article VI, the parties hereto shall cause the Merger to be consummated
by filing a  certificate  of  merger  (the  "Certificate  of  Merger")  with the
Secretary  of State of the State of  Delaware,  in such form as  required by and
executed in  accordance  with the relevant  provisions of the DGCL (the date and
time of such  filing,  or such  later date and time as may be  specified  in the
Certificate of Merger by mutual agreement of Parent, Merger Sub and the Company,
being the "Effective Time").

                  1.3  Effect of the Merger.   At the Effective Time, the effect
of the Merger  shall be as provided in the  applicable  provisions  of the DGCL,
including Section 259 thereof. Without limiting the generality of the foregoing,
and subject thereto,  at the Effective Time, all the assets,  property,  rights,
privileges,  immunities,  powers and  franchises  of the  Company and Merger Sub
shall vest in the Surviving Corporation,  and all debts,  liabilities and duties
of the Company and Merger Sub shall become the debts,  liabilities and duties of
the Surviving Corporation.

                  1.4  Certification of  Incorporation; Bylaws. Unless otherwise
determined  by Parent prior to the Effective  Time,  at the  Effective  Time and
without  any  further  action  on  the  part  of the  parties  hereto,  (a)  the
Certificate  of  Incorporation  of  Merger  Sub  shall  be  the  Certificate  of
Incorporation of the Surviving  Corporation until thereafter amended as provided
by the DGCL;  provided that Article First of the Certificate of Incorporation of
Merger Sub shall be amended to read in its entirety as follows: "The name of the
corporation  is  "MapQuest.com,  Inc." and (b) the Bylaws of Merger Sub shall be
the Bylaws of the Surviving  Corporation until thereafter amended as provided by
the DGCL.

                  1.5   Directors and  Officers.  The directors  of  Merger  Sub
immediately  prior to the Effective  Time shall be the initial  directors of the
Surviving Corporation, each to hold office in accordance with the Certificate of
Incorporation and the Bylaws of the Surviving Corporation until their respective
successors  are duly elected or appointed  and  qualified or until their earlier
death,  resignation  or removal in accordance  with the Surviving  Corporation's
Certificate of Incorporation and Bylaws. The officers of the Company immediately
prior to the Effective Time shall be the initial officers of the Surviving
Corporation.

                                     2



                  1.6  Conversion of Company Common Stock, Etc. At the Effective
Time,  by virtue of the Merger and without any action on the part of the parties
hereto or the holders of the following securities:

         (a) Subject to the  provisions  of this Article I, each share of Common
Stock,  par value $.001 per share,  of the Company (the "Company  Common Stock")
issued and outstanding  immediately  prior to the Effective Time (other than any
shares of the Company  Common  Stock to be canceled  pursuant to Section 1.7 and
subject to Section 1.10 and Section 1.1) will be  converted  automatically  into
the right to  receive  0.31558  of a fully  paid and  nonassessable  share  (the
"Exchange  Ratio") of the Common  Stock,  par value $0.01 per share (the "Parent
Common Stock"), of Parent (and a related portion of a Parent Right in accordance
with Section 1.6(b) hereof)(the "Merger Consideration").

         (b) Each share of the Parent Common Stock to be issued upon  conversion
of the Company Common Stock in accordance  with Section 1.6(a) shall include the
corresponding  percentage  of a right (a "Parent  Right") to purchase  shares of
Series A-1  Junior  Participating  Preferred  Stock,  $.01 par value,  of Parent
pursuant  to the Rights  Agreement  dated as of May 12,  1998,  as amended  (the
"Parent  Rights  Agreement"),  between  Parent and  BankBoston,  N.A., as Rights
Agent.  Prior  to  the  Distribution  Date  (as  defined  in the  Parent  Rights
Agreement), all references in this Agreement to the Parent Common Stock shall be
deemed to include Parent Rights.

         (c) Each share of the  Company  Common  Stock  issued  and  outstanding
immediately  prior to the  Effective  Time shall  automatically  be redeemed and
canceled and shall cease to exist, and each holder of a certificate representing
any such  Company  Common  Stock  shall  cease to have any rights  with  respect
thereto,  except the right to receive the Merger  Consideration  and any cash in
lieu of  fractional  shares  of  Parent  Common  Stock to be  issued  or paid in
consideration  therefor upon surrender of such  certificate  in accordance  with
Section 1.12 hereof, without interest.

                  1.7  Cancellation of Treasury Stock and Parent-Owned Stock.

         (a) Each share of the Company  Common Stock held in the treasury of the
Company, if any, and each share of Company Common Stock, if any, owned by Parent
or Merger Sub, in each case  immediately  prior to the Effective Time,  shall be
canceled  and  extinguished  without  any  conversion  thereof and no payment or
distribution shall be made with respect thereto.


                                       3




                  1.8   Stock Options and Warrants.

         (a) At the Effective Time, all options to purchase Company Common Stock
then  outstanding  under the  Company's  1995 Stock Option Plan, as amended (the
"1995 Plan"),  the  Company's  1999 Stock Plan, as amended (the "1999 Plan" and,
together  with the 1995 Plan,  the  "Option  Plans") by virtue of the Merger and
without any action on the part of the holder thereof, shall be assumed by Parent
in accordance with Section 5.5.

         (b)      The Company and its Board of Directors shall promptly take all
actions  necessary to ensure that  following the Effective Time no holder of any
options or other  rights  pursuant to, nor any  participant  in or party to, the
Option  Plans or any other  Employee  Plan (as  defined  herein) or other  plan,
program,  arrangement,  agreement or other commitment providing for the issuance
or grant of any  interest in respect of the capital  stock of the Company or any
Subsidiary  of the Company  will have any rights  thereunder  to acquire  equity
securities,  or any right to payment in  respect  of the equity  securities,  of
Parent, the Company, or the Surviving  Corporation or any of their Subsidiaries,
except as provided herein.

                  1.9  Capital Stock of Merger Sub.  Each share of Common Stock,
par value $0.01 per share,  of Merger Sub (the "Merger Sub Common Stock") issued
and outstanding  immediately  prior to the Effective Time shall be automatically
converted into one validly issued,  fully paid and nonassessable share of common
stock of the Surviving  Corporation and shall  thereafter  constitute all of the
issued and outstanding  capital stock of the Surviving  Corporation.  Each stock
certificate  of Merger  Sub  evidencing  ownership  of any  shares of Merger Sub
Common  Stock shall  continue to  evidence  ownership  of such shares of capital
stock of the Surviving Corporation.

                  1.10   Adjustments to  Exchange Ratio.  Without  limiting  any
other  provision  of this  Agreement,  the  Exchange  Ratio shall be adjusted to
reflect  fully the effect of any stock  split,  reverse  split,  stock  dividend
(including any dividend or  distribution of securities  convertible  into Parent
Common Stock or Company Common Stock), reorganization, recapitalization or other
like  change  with  respect  to Parent  Common  Stock or  Company  Common  Stock
occurring after the date hereof and prior to the Effective Time.

                  1.11 Fractional Shares.  No certificates or scrip representing
fractional  shares of Parent Common Stock shall be issued in connection with the
Merger, and such fractional  interests will not entitle the owner thereof to any
rights of a Stockholder  of Parent.  In lieu  thereof,  each holder of shares of
Company Common Stock exchanged pursuant to Section 1.6 or of options or warrants
exchanged  pursuant  to Section  1.8(b) who would  otherwise  be  entitled  to a
fraction of a share of Parent  Common Stock (after  aggregating  all  fractional
shares of Parent  Common Stock to have been  otherwise  received by such holder)
shall  receive from Parent an amount of cash  (rounded down to the nearest whole
cent and without  interest)  equal to the product of such  fractional  part of a
share of Parent Common Stock multiplied by the average


                                      4





closing price per share of Parent Common Stock  (rounded to the nearest cent) on
the New York Stock  Exchange,  Inc. (the "NYSE") (as reported in the Wall Street
Journal, or, if not reported therein, any other authoritative source selected by
Parent)  for the 20 trading  days ending on the third  trading  day  immediately
prior to (and excluding the date of) the Effective Time.

                  1.12     Surrender of Certificates.

         (a) Exchange Agent. Prior to the Effective Time, Parent shall designate
a bank or trust company to act as the Exchange Agent in the Merger.

         (b) Parent to Provide  Common Stock.  When and as needed,  Parent shall
make  available  to the  Exchange  Agent for  exchange in  accordance  with this
Article I, through such  reasonable  procedures as Parent may adopt,  sufficient
shares of Parent Common Stock to be exchanged pursuant to Section 1.6.

         (c)  Exchange  Procedures.  Promptly  after  the  Effective  Time,  the
Surviving  Corporation  shall  cause to be mailed to each  holder of record of a
certificate or  certificates  (the  "Certificates")  that  represented as of the
Effective  Time  outstanding  shares of  Company  Common  Stock to be  exchanged
pursuant to Section  1.6, a letter of  transmittal  (which  shall  specify  that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon delivery of the  Certificates to the Exchange Agent and shall be
in such form and have such other  provisions as Parent may  reasonably  specify)
and  instructions  for use in effecting  the  surrender of the  Certificates  in
exchange for  certificates  representing  shares of Parent  Common  Stock.  Upon
surrender of a Certificate to the Exchange  Agent,  together with such letter of
transmittal,  duly  completed  and  validly  executed  in  accordance  with  the
instructions  thereto,  and such other documents as may be required  pursuant to
such  instructions,  the holder of such Certificate shall be entitled to receive
in exchange  therefor a certificate  representing  the number of whole shares of
Parent Common Stock and payment in lieu of  fractional  shares which such holder
has the right to receive  pursuant to Sections 1.6 and 1.11, after giving effect
to any required (as defined  herein) Tax  withholdings,  and the  Certificate so
surrendered  shall  forthwith be canceled.  At any time following 6 months after
the Effective  Time, all or any number of shares of Parent Common Stock (and any
or all cash  payable  in lieu of  fractional  shares  of  Parent  Common  Stock)
deposited  with or made  available  to the  Exchange  Agent  pursuant to Section
1.12(b),   which  remain  undistributed  to  the  holders  of  the  Certificates
representing  shares of Company Common Stock,  shall be delivered to Parent upon
demand,  and  thereafter  such holders of  unexchanged  shares of Company Common
Stock shall be entitled to look only to Parent  (subject to abandoned  property,
escheat or other similar laws) only as general creditors thereof with respect to
the  shares of Parent  Common  Stock for  payment  upon due  surrender  of their
Certificates.

         (d) Distributions  With Respect to Unexchanged  Shares. No dividends or
other  distributions  declared or made after the Effective  Time with respect to
shares


                                        5





of Parent Common Stock with a record date after the Effective  Time will be paid
to the holder of any unsurrendered  Certificate with respect to the whole shares
of Parent  Common Stock  represented  thereby until the holder of record of such
Certificate  shall  surrender  such  Certificate.  Subject  to  applicable  law,
following  surrender of any such Certificate,  there shall be paid to the record
holder of the  certificates  representing  whole  shares of Parent  Common Stock
issued in exchange  therefor,  without interest,  at the time of such surrender,
the amount of  dividends  or other  distributions  with a record  date after the
Effective  Time and  payable  between  the  Effective  Time and the time of such
surrender with respect to such whole shares of Parent Common Stock.

         (e) Transfers of  Ownership.  If any  certificate  for shares of Parent
Common  Stock is to be  issued  in a name  other  than  the  name in  which  the
Certificate  surrendered  in  exchange  therefor  is  registered,  it  will be a
condition of the issuance  thereof that (i) the Certificate so surrendered  will
be properly  endorsed  and  otherwise  in proper form for  transfer and that the
Person  requesting  such  exchange  will have paid any  transfer  or other Taxes
required by reason of the issuance of a certificate  for shares of Parent Common
Stock in a name other than the name of the registered  holder of the Certificate
surrendered or (ii)  established  to the  satisfaction  of Parent,  or any agent
designated by Parent, that such Tax has been paid or is not applicable.

         (f) No  Liability.  Notwithstanding  anything  to the  contrary in this
Agreement,  none of the Exchange Agent,  Parent, the Merger Sub or the Surviving
Corporation  shall be liable to a holder of a Certificate  for any Parent Common
Stock (and any cash payable for fractional  shares of Parent Common Stock or any
other  amount  due, if any) that was  properly  delivered  to a public  official
pursuant to any applicable abandoned property, escheat or similar Law.

         (g)  Withholding of Tax.  Parent or the Exchange Agent will be entitled
to deduct and withhold from the consideration otherwise payable pursuant to this
Agreement  to any holder of Company  Common Stock such amounts as Parent (or any
Affiliate  thereof) or the Exchange Agent shall determine in good faith they are
required to deduct and withhold with respect to the making of such payment under
the Code, or any provision of federal,  state,  local or foreign Tax Law. To the
extent  that  amounts  are so withheld  by Parent or the  Exchange  Agent,  such
withheld  amounts will be treated for all  purposes of this  Agreement as having
been paid to the  holder of the  Company  Common  Stock in  respect of whom such
deduction and withholding were made by Parent.

                  1.13  Further Ownership  Rights in Company  Common Stock.  All
shares of Parent  Common Stock issued upon the surrender for exchange of Company
Common Stock in accordance  with the terms of this Article I (including any cash
paid  in  respect  thereof)  shall  be  deemed  to  have  been  issued  in  full
satisfaction  of all rights  pertaining  to such Company  Common  Stock.  At the
Effective  Time, the stock  transfer  books of the Company shall be closed,  and
thereafter  there shall be no further  registration  of  transfers  of shares of
Company Common Stock

                                      6






on the records of the Surviving Corporation.  From and after the Effective Time,
the holders of  Certificates  evidencing  ownership of shares of Company  Common
Stock  outstanding shall cease to have any rights with respect to such shares of
Company  Common  Stock except as  otherwise  provided for herein.  If, after the
Effective Time,  Certificates are presented to the Surviving Corporation for any
reason, they shall be canceled and exchanged as provided in this Article I.

                  1.14 Closing. Unless this Agreement shall have been terminated
and the transactions  contemplated by this Agreement  abandoned  pursuant to the
provisions  of Article  VII,  and subject to the  provisions  of Article VI, the
closing of the Merger  (the  "Closing")  will take place at 10:00 a.m.  (Eastern
time) on a date (the "Closing  Date") to be mutually agreed upon by the parties,
which  date  shall be not  later  than the  third  Business  Day  after  all the
conditions  set forth in  Article  VI shall  have been  satisfied  (or waived in
accordance  with  Section  7.5,  to the extent the same may be  waived),  unless
another time and/or date is agreed by the parties hereto. The Closing shall take
place at the offices of Simpson Thacher & Bartlett,  425 Lexington  Avenue,  New
York, New York or such other place as the parties hereto otherwise agree.

                  1.15 Lost, Stolen or Destroyed Certificates.  In the event any
Certificates  evidencing  Company  Common Stock shall have been lost,  stolen or
destroyed,  the Exchange Agent shall issue in exchange for such lost,  stolen or
destroyed  Certificates,  upon the  making of an  affidavit  of that fact by the
holder  thereof,  such  shares of Parent  Common  Stock and cash for  fractional
shares, if any, as may be required pursuant to Section 1.11; provided,  however,
that Parent may, in its discretion and as a condition  precedent to the issuance
thereof,  require the owner of such lost,  stolen or destroyed  certificates  to
deliver a bond in such sum as it may reasonably  direct as indemnity against any
claim that may be made against  Parent or the Exchange Agent with respect to the
Certificates alleged to have been lost, stolen or destroyed.

                  1.16  Tax  Consequences. For federal income tax purposes,  the
parties intend that the Merger be treated as a reorganization within the meaning
of Section 368(a) of the Code, and that this Agreement  shall be, and is hereby,
adopted as a plan of reorganization for purposes of Section 368 of the Code. The
parties  shall  not  take a  position  on any Tax  Return  (as  defined  herein)
inconsistent with this Section 1.16.

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

entitled to receive any payment or other value based on the  revenues,  earnings
or financial  performance,  stock price  performance  or other  attribute of the
Company  or any of its  Subsidiaries  or  assets  or  calculated  in  accordance

Stockholders  is a party or by which any of them is bound  with  respect  to the
issuance, holding,  acquisition,  voting or disposition of any shares of capital
stock of the Company or any of its Subsidiaries.

                  2.4  Authority; Enforceability.  The Company has all necessary
corporate  power and  authority  to execute and  deliver  this  Agreement,  each
Related Agreement (as defined herein) to which it is a party and each instrument
required to be executed and  delivered by it at the Closing,  and to perform its
obligations   hereunder  and  thereunder  and  to  consummate  the  transactions
contemplated  hereby and thereby.  The  execution and delivery by the Company of
this  Agreement  and  each  Related  Agreement  to  which  it  is a  party,  the
performance of its obligations hereunder and thereunder, and the consummation by
the Company of the transactions  contemplated hereby and thereby, have been duly
and  validly   authorized  by  all  corporate  action  and  no  other  corporate
proceedings on the part of the Company are necessary to authorize this

                                     10






Agreement or any Related  Agreement to which it is a party or to consummate  the
transactions  so  contemplated  (other  than,  with  respect to the Merger,  the
approval  and  authorization  of this  Agreement  by votes of the  holders  of a
majority of the outstanding Company Common Stock in accordance with Delaware law
and the Company's  Certificate of  Incorporation  and Bylaws) herein or therein.
Each of this  Agreement  and Related  Agreements to which it is a party has been
duly and validly  executed and  delivered  by the Company and,  assuming the due
authorization,  execution  and  delivery  thereof  by  Parent  and  Merger  Sub,
constitutes a legal,  valid and binding  obligation  of the Company  enforceable
against the Company in accordance with its terms.

                  2.5  Required Vote.   As of the  date hereof  and,  except  as

Agreements to which it is a party and the other transactions contemplated hereby
and  thereby to the  Stockholders  of the Company  and (iv)  directed  that this
Agreement be submitted to the Stockholders of the Company for their approval and
authorization.  The affirmative vote of a majority of all outstanding  shares of
Company  Common  Stock is the only vote of the holders of any class or series of
capital stock of the Company  necessary to approve and authorize this Agreement,
the  Merger,  the Related  Agreements  and the other  transactions  contemplated
hereby and thereby.  As of December 20, 1999,  the holders of the Company Common
Stock that are parties to the Stockholders  Agreement own  (beneficially  and of
record) and have the right to vote, in the aggregate, approximately 75.0% of the
total issued and outstanding Company Common Stock.

                  2.6  No Conflict; Required Filings and Consents.

notice or lapse of time or both  would  become a default)  under,  or impair the
Company's or any of its Subsidiaries'  rights or alter the rights or obligations
of any  third  party  under,  or give  to  others  any  rights  of  termination,
amendment,  acceleration or cancellation of, or result in the creation of a Lien
on any of the  properties  or assets of the  Company or any of its  Subsidiaries
pursuant to, any note, bond, mortgage, indenture, Contract, permit, franchise or
other instrument or obligation

in  accordance  with  Delaware  law or (C) where  the  failure  to  obtain  such

         Stockholders,  directors,  officers, employees or agents of the Company
         that will result in any  obligation  (absolute  or  contingent)  of the
         Company or any of its  Subsidiaries  to make any payment to any current
         or former Stockholders, directors, officers, employees or agents of the
         Company   following   either  the   consummation  of  the  transactions

each case except that the enforcement  thereof may be limited by (A) the effects
of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and

passage of time or both, would  constitute such a default,  breach or violation.

Section 2.7 and the disclosures  made pursuant  thereto will not be construed or

except,  in the  case of  clauses  (ii) and  (iii),  for any  such  failures  of

in the  aggregate,  reasonably  be expected to have a Material  Adverse  Effect,
neither the  Company  nor any of its  Subsidiaries  has  received  notice of any
revocation or modification of any federal,  state, local or foreign Governmental
Authority,  any Approval of any federal,  state,  local or foreign  Governmental

thereto (including all applicable  requirements for notification,  reporting and
disclosure to participants of the Department of Labor,  Internal Revenue Service
or  Secretary of the  Treasury);  the Company and each of its  Subsidiaries  and
ERISA  Affiliates  have  performed  in all  material  respects  all  obligations
required to be performed by them under each Employee Plan and are not in default
under or violation  of, and have no Knowledge of any default or violation by any
other Person with  respect to, any of the Employee  Plans;  each  Employee  Plan

         (c) No Employee Plan is an "employee  pension benefit plan" (within the
meaning of Section 3(2) of ERISA) subject to Title IV of ERISA,  and neither the
Company  nor any  Subsidiary  or ERISA  Affiliate  has ever  partially  or fully

Security  Act,  to the  extent  such  requirements  are  applicable.  Except  as
disclosed in Section  2.13(d) of the Company  Disclosure  Schedule,  no Employee
Plan or written or oral agreement  exists which obligates the Company to provide
health  care  coverage,  medical,  surgical,  hospitalization,  death or similar
benefits  (whether  or not  insured) to any  employee or former  employee of the
Company  or  any  of  its  Subsidiaries  following  such  employee's  or  former

Schedule,  (i) no event has occurred and no condition  exists that would subject
the  Company or any of its  Subsidiaries,  either  directly  or by reason of its
affiliation with any ERISA Affiliate,  to any Tax, fine, Lien,  penalty or other
liability  imposed by ERISA; (ii) for each Employee Plan with respect to which a
Form 5500 has been filed,  no material  change has occurred  with respect to the
matters  covered  by the most  recent  Form  since  the date  thereof;  (iii) no

Affiliates has taken or agreed to take any action,  failed to take any action or
is aware of any fact or  circumstance  that would  prevent  (i) the Merger  from
being treated for financial  accounting  purposes as a "pooling of interests" in
accordance  with GAAP and the  Regulations  of the SEC or (ii) the  Merger  from
constituting a reorganization within the meaning of Section 368(a) of the Code.

         (c) The Company has no knowledge of any reason why it may not receive a
letter  from  Ernst & Young LLP (the  "Company's  Accountants")  dated as of the
Closing  Date and  addressed to the Company in which the  Company's  Accountants
will concur with the Company  management's  conclusion that no conditions  exist
related to the Company that would preclude Parent from accounting for the Merger
as a "pooling of interests."

         (d) Section 2.24(d) of the Company Disclosure  Schedule contains a true
and complete  list of all Persons who, to the  Knowledge of the Company,  may be
deemed to be Affiliates of the Company,  excluding all of its  Subsidiaries  but
including all directors and executive officers of the Company.

                  2.24  Brokers.  No  broker,  financial   advisor,   finder  or

transactions  contemplated by this Agreement based upon  arrangements made by or
on behalf of the Company,  except for  BancBoston  Robertson  Stephens Inc. (the

complete copy of, all agreements  between the Company and the Company  Financial
Advisors pursuant to which such Person would be entitled to any payment relating

neither the  Company  nor any of its  Subsidiaries  nor any  director,  officer,

funds  for  unlawful  contributions,  gifts,  entertainment  or  other  unlawful
payments relating to political  activity,  (ii) made any unlawful payment to any
foreign  or  domestic  government  official  or  employee  or to any  foreign or
domestic  political  party or campaign or violated any  provision of the Foreign

made any payment,  entered into any agreement or  arrangement or taken any other
action in violation of Section  1128B(b) of the Social Security Act, as amended,

Stockholders or other Affiliates of the Company and its Subsidiaries,  or any of
their respective  Affiliates or family members, on the other (except for amounts
due as normal salaries and bonuses and in reimbursement  of ordinary  expenses),
and (ii) except for the Outstanding  Employee Options, at the Closing,  all such
Contracts, transactions, indebtedness and other arrangements shall be terminated

                  2.27  Opinion of Financial Advisor.  The  Company has received
the written opinion of the Company Financial Advisors to the effect that, in its

Company has provided copies of such opinion to Parent.

                  2.28  Disclaimer of Other Representation  and Warranties.  The

                                   ARTICLE III

             REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB

                  Parent and Merger Sub hereby, jointly and severally, represent
and warrant to the Company as follows:

                                      30






                  3.1 Organization and Qualification.  Each of Parent and Merger
Sub is a corporation duly organized, validly existing and in good standing under
the  laws of  Delaware.  Parent  has  all  the  requisite  corporate  power  and
authority,  and is in possession of all  Approvals  necessary to own,  lease and
operate  its  properties  and to  carry  on  its  business  as it is  now  being
conducted,  except  where the failure to be so  qualified,  existing and in good
standing or to have such power,  authority and Approvals could not, individually
or in the aggregate,  reasonably be expected to have a Material  Adverse Effect.
Each of  Parent  and  Merger  Sub is duly  qualified  or  licensed  as a foreign
corporation to do business,  and is in good standing, in each jurisdiction where
the character of the properties owned, leased or operated by it or the nature of
its activities makes such qualification or licensing necessary,  except for such
failures to be so duly  qualified  or licensed and in good  standing  that could
not, either  individually or in the aggregate,  reasonably be expected to have a
Material  Adverse  Effect.  Merger Sub is a  newly-formed  single purpose entity
which has been formed  solely for the  purposes of the Merger and will not carry
on any business or engage in any activities other than those reasonably  related
to the Merger.

                  3.2   Capitalization.

         (a) As of the date  hereof,  the  authorized  capital  stock of  Parent
consists of (i)  6,000,000,000  shares of Parent  Common  Stock of which,  as of
December  21,  1999,   approximately   2,270,342,472   shares  were  issued  and
outstanding,  and (ii) 5,000,000  shares of preferred  stock, par value $.01 per
share,   including  500,000  reserved  for  issuance  under  the  Parent  Rights
Agreement,  of which  none are  issued or  outstanding.  All of the  outstanding
shares of Parent  Common  Stock are,  and all shares to be issued as part of the
Merger  Consideration  will be, when issued in accordance with the terms hereof,
duly authorized, validly issued, fully paid and nonassessable.

         (b) As of the date hereof,  the authorized  capital stock of Merger Sub
consists of 1,000  shares of Merger Sub Common  Stock,  of which 1,000 shares of
Merger Sub Common Stock are outstanding. All of the outstanding shares of Merger
Sub Common Stock are owned by Parent.

                  3.3  Authority; Enforceability.  Each of Parent and Merger Sub
has all  requisite  corporate  power and  authority  to execute and deliver this
Agreement and each instrument required hereby to be executed and delivered by it
at the Closing,  to perform its  obligations  hereunder  and  thereunder  and to
consummate the transactions  contemplated hereby and thereby.  The execution and
delivery by each of Parent and Merger Sub of this Agreement and each  instrument
required  hereby to be executed  and  delivered  by Parent and Merger Sub at the
Closing  and the  performance  of their  respective  obligations  hereunder  and
thereunder  have been duly and validly  authorized  by the Board of Directors of
each of Parent and Merger  Sub and by Parent as the sole  Stockholder  of Merger
Sub.  Except  for  filing  of the  Certificate  of  Merger,  no other  corporate
proceedings on the part of Parent or Merger Sub are necessary to authorize the

                                     31






consummation of the transactions  contemplated  hereby.  This Agreement has been
duly executed and  delivered by each of Parent and Merger Sub and,  assuming due
authorization,  execution  and  delivery  hereof by the Company,  constitutes  a
legal,  valid  and  binding  obligation  of  each  of  Parent  and  Merger  Sub,
enforceable against each of Parent and Merger Sub in accordance with its terms.

                  3.4   No Conflict; Required Filings and Consents.

         (a) The  execution  and  delivery  by  Parent  and  Merger  Sub of this
Agreement do not, and the  performance of this Agreement by Parent or Merger Sub
shall not, (i) conflict  with or violate the  Certificate  of  Incorporation  or
Bylaws of Parent or the Certificate of Incorporation or Bylaws of Merger Sub, or
(ii) conflict with or violate any Law or Order in each case applicable to Parent
or Merger Sub or by which its or any of their respective  properties is bound or
affected,  except in the case of clause (ii) above,  for any such  conflicts  or
violations  that could not,  individually  or in the  aggregate,  reasonably  be
expected to have a Material Adverse Effect.

         (b) The  execution  and  delivery  by  Parent  and  Merger  Sub of this
Agreement do not, and the performance by Parent and Merger Sub of this Agreement
shall not,  require  Parent or Merger Sub to obtain the Approval of, observe any
waiting  period  imposed  by, or make any filing  with or  notification  to, any
Governmental  Authority,  domestic or foreign,  except for (A)  compliance  with
applicable  requirements of the Securities Act, the Exchange Act, Blue Sky Laws,
or  the  pre-Merger  notification   requirements  of  the  HSR  Act  or  Foreign
Competition Laws, (B) the filing of the Certificate of Merger in accordance with
Delaware  law,  (C) the filing of a listing  application  or other  documents as
required by the NYSE or (D) where the failure to obtain  such  Approvals,  or to
make such filings or notifications,  would not individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect.

                  3.5   SEC Filings; Financial Statements.

         (a) Parent has filed all  reports  and  documents  required to be filed
with the SEC since  January 1, 1999  (collectively,  the "Parent  SEC  Reports")
pursuant to the federal  securities  Laws and Regulations of the SEC promulgated
thereunder,  and all Parent SEC Reports have been filed in all material respects
on a timely  basis.  The Parent SEC Reports  were  prepared in  accordance,  and
complied as of their respective filing dates in all material respects,  with the
requirements of the Exchange Act and the Regulations  promulgated thereunder and
did not at the time they were  filed (or if amended  or  superseded  by a filing
prior to the date hereof,  then on the date of such  filing)  contain any untrue
statement  of a material  fact or omit to state a material  fact  required to be
stated  therein or necessary  in order to make the  statements  therein,  in the
light of the circumstances under which they were made, not misleading.


                                      32






         (b) Each of the consolidated financial statements  (including,  in each
case, any related notes thereto) contained in Parent SEC Reports (i) complied in
all material respects with applicable accounting  requirements and the published
Regulations  of the SEC with respect  thereto,  (ii) were prepared in accordance
with GAAP  (except,  in the case of unaudited  statements,  as permitted by Form
10-Q of the SEC) applied on a consistent  basis  throughout the periods involved
(except as may be  expressly  described  in the notes  thereto) and (iii) fairly
presents  the  consolidated  financial  position of Parent as at the  respective
dates thereof and the consolidated  results of its operations and cash flows for
the periods  indicated,  except that the unaudited interim financial  statements
included in the  Company's  Form 10-Q  reports were or are subject to normal and
recurring  year-end  adjustments  that have not been and are not  expected to be
material in amount to Parent.

                  3.6   Absence of Litigation.  Except  as  described in Section
3.6 of the Parent Disclosure  Schedule or expressly  described in the Parent SEC
Reports  filed and  publicly  available  prior to the date  hereof,  there is no
Litigation  pending  on behalf of or  against  or, to the  Knowledge  of Parent,
threatened against Parent,  any of its Subsidiaries,  or any of their respective
properties or rights,  before or subject to any Court or Governmental  Authority
which  if  adversely  determined  would,   individually  or  in  the  aggregate,
reasonably be expected to have a Material Adverse Effect. Neither Parent nor any
of its  Subsidiaries  is subject to any  outstanding  Litigation or Order which,
individually  or in the  aggregate,  has had or could  reasonably be expected to
have a Material Adverse Effect.

                  3.7  Registration Statement; Proxy Statement/Prospectus.  None
of the  information  supplied  by  Parent  for  inclusion  in  the  Registration
Statement  shall,  at the time such  document is filed,  at the time  amended or
supplemented, or at the time the Registration Statement is declared effective by
the SEC,  contain any untrue  statement of a material  fact or omit to state any
material  fact  required to be stated  therein or necessary in order to make the
statements  therein,  in light of the circumstances  under which they were made,
not misleading.  None of the information supplied by Parent for inclusion in the
Proxy  Statement  shall,  on the date the Proxy Statement is first mailed to the
Stockholders of the Company, at the time of Company Stockholders' Meeting and at
the Effective Time,  contain any untrue  statement of a material fact or omit to
state any material fact required to be stated therein necessary in order to make
the statements therein, in light of the circumstances under which they are made,
not false or misleading.  The  Registration  Statement will comply as to form in
all material respects with the provisions of the Securities Act. Notwithstanding
the foregoing, Parent makes no representation, warranty or covenant with respect
to  any  information   supplied  by  the  Company  which  is  contained  in  the
Registration Statement or Proxy Statement.

                  3.8  Pooling; Tax Matters. To the Knowledge of Parent, neither
Parent and Merger  Sub nor any of their  Affiliates  has taken or agreed to take
any action or failed to take any action  that would  prevent (a) the Merger from
being treated for financial accounting purposes as

                                    33






a "pooling of interests" in accordance  with GAAP and the Regulations of the SEC
or (b) the Merger  from  constituting  a  reorganization  within the  meaning of
Section 368(a) of the Code.

not, nor shall it permit any of its Affiliates or Subsidiaries  to, nor shall it

other equity securities of the Company or any Material  Subsidiary  representing

benefits to Parent or its Affiliates of the  transactions  contemplated  hereby.
The Company shall immediately cease and cause to be terminated,  and shall cause
its Subsidiaries and all Company  Representatives  to immediately  terminate and
cause to be  terminated,  all  existing  discussions  or  negotiations  with any

         (b)  Notwithstanding  the  foregoing,  the Company may  participate  in
discussions or  negotiations  with, or furnish  information  with respect to the
Company pursuant to a confidentiality  agreement with terms no less favorable to
the Company  than those in effect  between the Company and Parent to, any Person
if and only if (x) such Person has  submitted an  unsolicited  bona fide written
Acquisition  Proposal  to the  Company's  Board of  Directors,  (y)  neither the
Company  nor any of the  Company  Representatives  shall have  violated  Section
4.2(a)  and (z) the  Board of  Directors  of the  Company  (i)  determines  by a
majority  vote in its good  faith  judgment,  after  consultation  with  outside
counsel,  that taking such action is required to satisfy the fiduciary duties of
such Board under applicable Law and (ii) provides prior written notice to Parent
of its decision to so participate or furnish.

         (c) Except as set forth in the following sentence, neither the Board of
Directors  of the  Company  nor any  committee  thereof  shall  (1)  approve  or
recommend,  or propose to approve or recommend,  any Acquisition  Proposal other
than the  Merger,  (2)  withdraw or modify or propose to withdraw or modify in a
manner  adverse to Parent or Merger Sub its  approval or  recommendation  of the
Merger,  this  Agreement or the  transactions  contemplated  hereby,  (3) upon a
request by Parent to reaffirm its approval or  recommendation  of this Agreement
or the  Merger,  fail to do so within two  Business  Days after such  request is
made,  (4)  approve,  enter,  or  permit or cause the  Company  or any  Material
Subsidiary  to  enter,  into any  letter  of  intent,  agreement  in  principle,
acquisition  agreement or other  similar  agreement  related to any  Acquisition
Proposal,  or (5) resolve or announce its intention to do any of the  foregoing.
The immediately preceding sentence  notwithstanding,  in the event that prior to
the Company Stockholders' Meeting the Board of Directors of the Company receives
a Superior  Proposal (as defined herein),  the Board of Directors of the Company
may (i)  withdraw  or  modify,  or propose to  withdraw  or modify,  in a manner
adverse to Parent or Merger Sub its  approval or  recommendation  of the Merger,
this Agreement or the transactions  contemplated  hereby,  (ii) fail to reaffirm
its  approval  or  recommendation  of this  Agreement  or the Merger  within two
Business  Days after a request by Parent to do so, or (iii)  resolve or announce
its intention to do any of the actions set forth in the preceding clauses (i) or
(ii), if (x) after consultation with outside counsel, such Board determines by a
majority vote of directors in their good faith  judgment that taking such action
is required to satisfy the fiduciary  duties of such Board under  applicable Law
and (y) the Company  furnishes Parent two Business Days' prior written notice of
the taking of such action  (which  notice  shall  include a  description  of the
material terms and  conditions of the Superior  Proposal and identify the person
making the same).  For purposes of this  Agreement,  (A)  "Material  Subsidiary"
means any Subsidiary of the Company whose consolidated  revenues,  net income or
assets  constitute  20% or more of the  revenues,  net  income  or assets of the
Company  and its  Subsidiaries  taken  as a whole,  and (B) the  term  "Superior
Proposal"  means  any  bona  fide  Acquisition  Proposal  to  effect  a  merger,
consolidation or sale of all or substantially all

                                    38






of the assets or capital  stock of the Company which is on terms which the Board
of Directors of the Company  determines  by a majority  vote of its directors in
their good faith  judgment  (based on the written  opinion,  with only customary
qualifications,  of a financial advisor of nationally recognized reputation that
the consideration provided in such Acquisition Proposal likely exceeds the value
of the consideration  provided for in the Merger), after taking into account all
relevant  factors,  including any conditions to such Acquisition  Proposal,  the
form of consideration  contemplated by such Acquisition Proposal,  the timing of
the  closing  thereof,  the risk of  nonconsummation,  the ability of the Person
making the Acquisition Proposal to finance the transactions contemplated thereby
and any required filings or Approvals,  to be more favorable to the Stockholders
of the Company than the Merger (or any revised proposal made by Parent).

         (d) In  addition to the other  obligations  of the Company set forth in
this Section 4.2, the Company  shall  immediately  advise  Parent  orally and in
writing of any request for information with respect to any Acquisition Proposal,
or any inquiry with respect to or which could result in an Acquisition Proposal,
the material  terms and  conditions  of such  request,  Acquisition  Proposal or
inquiry,  and the  identity of the Person  making the same.  The  Company  shall
inform  Parent on a prompt and  current  basis of the status and  content of any
discussions  regarding  any  Acquisition  Proposal  with a  third  party  and as
promptly as  practicable  of any change in the price,  structure  or form of the
consideration  or material  terms of and  conditions  regarding any  Acquisition
Proposal or of any other developments or circumstances which could reasonably be
expected to culminate in the taking of any of the actions referred to in Section
4.2(c).  Nothing  contained  in this Section  4.2(d) shall  prevent the Board of
Directors  of the  Company  from  complying  with  Rule  14d-9  and  Rule  14e-2
promulgated under the Exchange Act.


                                    ARTICLE V

                              ADDITIONAL AGREEMENTS

         (a) The Company shall, promptly following the date hereof,  prepare and
file with the SEC a Proxy  Statement  relating to the Merger and this Agreement,
obtain and  furnish  the  information  required to be included by the SEC in the
Proxy  Statement  and  respond  promptly  to any  comments  made by the SEC with
respect to the Proxy Statement, and cause the Proxy Statement and the prospectus
to be  included  in the  Registration  Statement,  including  any  amendment  or
supplement thereto, to be mailed to its Stockholders at the earliest practicable
date after the  Registration  Statement  is declared  effective  by the SEC. The
Company shall use all reasonable efforts to obtain the necessary approval of the
Merger and this  Agreement by its  Stockholders.  Unless the Company  shall have
taken action  permitted by the second  sentence of Section  4.2(c),  the Company
shall not file with or supplementally provide to the SEC or mail to

                                       39






its  Stockholders  the Proxy  Statement or any amendment or  supplement  thereto
without Parent's prior consent, which consent shall not be unreasonably withheld
or  delayed.  The  Company  shall  allow  Parent's  full  participation  in  the
preparation of the Proxy  Statement and any amendment or supplement  thereto and
shall consult with Parent and its advisors  concerning any comments from the SEC
with respect thereto.

         (b) Parent shall prepare and file with the SEC a Registration Statement
on Form S-4, in which the Proxy Statement shall be included as a prospectus, and
the parties  hereto shall use all  reasonable  efforts to have the  Registration
Statement  declared  effective by the SEC as promptly as practicable  after such
filing.  Parent shall obtain and furnish the information required to be included
in the Registration Statement and, after consultation with the Company,  respond
promptly  to any  comments  made by the SEC  with  respect  to the  Registration
Statement.

         (c) The Proxy Statement shall include the  recommendation  of the Board
of Directors of the Company in favor of approval and adoption of this  Agreement
and the Merger,  except to the extent that the Company  shall have  withdrawn or
modified  its  recommendation  of this  Agreement  or the Merger as permitted by
Section 4.2(c).

         (d) Parent and the Company shall, as promptly as practicable,  make all
necessary  filiIngs with respect to the Merger under the  Securities Act and the
Exchange Act and the  Regulations  thereunder and under  applicable  Blue Sky or
similar securities Laws, and shall use all reasonable efforts to obtain required
Approvals with respect thereto.

         (e) Each party  hereto  agrees to furnish  all  information  concerning
itself  as  may be  reasonably  required  to  prepare  the  Proxy  Statement  or
Registration  Statement or to make such filings pursuant to Section 5.1(d). Each
party  hereto  agrees to correct any  information  provided by it for use in the
Proxy Statement or Registration Statement that has become false or misleading in
any material respect.

                  5.2  Meeting  of  Company's Stockholders.   The  Company shall
promptly after the date hereof take all action  necessary in accordance with the
DGCL and its Certificate of  Incorporation  and Bylaws to duly call, give notice
of and (unless Parent requests otherwise) hold the Company  Stockholders Meeting
as soon as practicable following the date upon which the Registration  Statement
becomes  effective and shall consult with Parent in connection  therewith.  Once
the Company Stockholders' Meeting has been called and noticed, the Company shall
not postpone or adjourn (other than for the absence of a quorum and then only to
a future date specified by Parent) the Company Stockholders' Meeting without the
consent of Parent.  The Board of Directors of the Company has declared that this
Agreement is advisable and, subject to Section 4.2(c), shall recommend that this
Agreement and the transactions contemplated hereby be approved and authorized by
the  Stockholders of the Company and include in the  Registration  Statement and
Proxy  Statement a copy of such  recommendations;  provided,  however,  that the
Board  of  Directors  of  the  Company  shall  submit  this   Agreement  to  the
Stockholders of the

                                     40






Company  whether  or not the  Board  of  Directors  of the  Company  at any time
subsequent  to making such  declaration  takes any action  permitted  by Section
4.2(c). The Company shall solicit from its Stockholders  proxies in favor of the
Merger and shall take all other action necessary or advisable to secure the vote
or consent of its  Stockholders  to  authorize  and approve the Merger.  Without
limiting  the  generality  of the  foregoing,  (i) the  Company  agrees that its
obligation  to  duly  call,  give  notice  of,  convene  and  hold  the  Company
Stockholders'  Meeting as required by this Section 5.2, shall not be affected by
the   withdrawal,   amendment  or   modification  of  the  Board  of  Directors'
recommendation  of approval and adoption of this Agreement and the  transactions
contemplated hereby, and (ii) the Company agrees that its obligations under this
Section 5.2 shall not be affected by the commencement,  public proposal,  public
disclosure or communication to the Company of any Acquisition Proposal.

                  5.3   Access to Information; Confidentiality.

         (a) Upon reasonable  notice, the Company shall (and shall cause each of
its Subsidiaries to) afford to the officers, employees, accountants, counsel and
other    representatives   and   agents   of   Parent   (collectively    "Parent
Representatives"),  reasonable access,  during the period prior to the Effective
Time, to all its  properties,  books,  Contracts,  commitments  and records and,
during such period,  the Company shall (and shall cause each of its Subsidiaries
to)  furnish  promptly to the other all  information  concerning  its  business,
properties,  books, Contracts,  commitments,  record and personnel as Parent may
reasonably request.  The Company shall (and shall cause each of its Subsidiaries
to) make available to the other party the appropriate individuals for discussion
of such  entity's  business,  properties  and  personnel as Parent or the Parent
Representatives  may  reasonably  request.  No  investigation  pursuant  to this
Section  5.3(a) shall affect any  representations  or  warranties of the parties
herein or the conditions to the obligations of the parties hereto.

         (b) Parent  shall keep all  information  obtained  pursuant  to Section
5.3(a)   confidential  in  accordance   with  the  terms  of  the   Confidential
Non-Disclosure   Agreement,   dated   October  5,  1999  (the   "Confidentiality
Agreement"),   between  Parent  and  the  Company.  Anything  contained  in  the
Confidentiality  Agreement  to the  contrary  notwithstanding,  the  Company and
Parent  hereby  agree that each such party may issue  press  release(s)  or make
other public announcements in accordance with Section 5.10.

                  5.4   Reasonable Best Efforts; Further Assurances.

         (a) Upon the  terms and  subject  to the  conditions  set forth in this
Agreement,  each party hereto shall use its reasonable  best efforts to take, or
cause to be taken,  all actions,  and do, or cause to be done, and to assist and
cooperate with the other party or parties in doing, all things necessary, proper
or advisable to consummate and make effective,  in the most  expeditious  manner
practicable,  the Merger and the other transactions  contemplated hereby, and by
the Related  Agreements.  The Company and Parent shall use its  reasonable  best
efforts to (i)

                                    41






as promptly as practicable, obtain all Approvals (including those referred to in
Sections  2.6(a)  and  2.6(b) and  Sections  2.6(a)  and  2.6(b) of the  Company
Disclosure  Schedule),  and the Company and Parent shall make all filings  under
applicable  Law required in  connection  with the  authorization,  execution and
delivery of this  Agreement  and the Option  Agreement by the Company and Parent
and the  consummation  by  them  of the  transactions  contemplated  hereby  and
thereby,  including the Merger (in connection  with which Parent and the Company
will  cooperate  with  each  other in  connection  with the  making  of all such
filings,  including  providing  copies of all such  documents to the  non-filing
party and its  advisors  prior to filings  and,  if  requested,  will accept all
reasonable additions,  deletions or changes suggested in connection  therewith);
(ii) furnish all information  required for any application or other filing to be
made pursuant to the DGCL or any other Law or any applicable  Regulations of any
Governmental Authority (including all information required to be included in the
Proxy  Statement  or  the   Registration   Statement)  in  connection  with  the
transactions  contemplated  by this  Agreement and the Related  Agreements;  and
(iii) lift,  rescind or mitigate  the effects of any  injunction  or other Order
adversely   affecting  the  ability  of  any  party  hereto  to  consummate  the
transactions contemplated hereby and thereby and to prevent, with respect to any
threatened  or such  injunction  or other Oder,  the issuance or entry  thereof,
provided,  however, that neither Parent nor any of its Affiliates shall be under
any obligation to (x) make proposals,  execute or carry out agreements or submit
to  Orders  providing  for the sale or other  disposition  or  holding  separate
(through the  establishment of a trust or otherwise) of any assets or categories
of assets of Parent,  any of its  Affiliates,  including its  Subsidiaries,  the
Company or the  holding  separate  of the  Company  Common  Stock or imposing or
seeking  to  impose  any  limitation  on the  ability  of  Parent  or any of its
Affiliates,  including its  Subsidiaries,  to conduct their business or own such
assets or to acquire,  hold or  exercise  full  rights of  ownership  of Company
Common  Stock,  or (y)  otherwise  take  any  step to  avoid  or  eliminate  any
impediment which may be asserted under any Law governing competition, monopolies
or restrictive  trade  practices  which,  in the reasonable  judgment of Parent,
might result in a limitation of the benefit  expected to be derived by Parent as
a result of the transactions  contemplated  hereby or might adversely affect the
Company or Parent or any of Parent's  Affiliates,  including  its  Subsidiaries.
Neither  party  hereto  will  take  any  action  which  results  in  any  of the
representations or warranties made by such party pursuant to Articles II or III,
as the case may be, becoming untrue or inaccurate in any material respect.

         (b) The  parties  hereto  shall use their  reasonable  best  efforts to
satisfy or cause to be satisfied all of the  conditions  precedent  that are set
forth  in  Article  VI,  as  applicable  to  each  of  them,  and to  cause  the
transactions  contemplated  by this  Agreement  to be  consummated.  Each  party
hereto,  at the  reasonable  request of another party hereto,  shall execute and
deliver such other  instruments and do and perform such other acts and things as
may be necessary or desirable for effecting  completely the consummation of this
Agreement  and the  transactions  contemplated  hereby.  In  furtherance  of the
foregoing, Parent shall use its reasonable best efforts to assist the Company in
satisfying  the  condition  set forth in Section  6.2(g),  including  reasonably
responding  to Company  requests  in  connection  with its efforts to retain the
employees  identified in Section 6.2(g) of the Parent Disclosure Schedule and to
satisfy such condition;

                                          42






provided,  however,  that Parent  shall not be  obligated  to pay or promise any
monies or additional compensation pursuant to this sentence.

         (c) The Company and Parent shall cooperate with one another:

               (i) in  connection  with  the  preparation  of  the  Registration
          Statement and the Proxy Statement;

               (ii) in connection with the preparation of any filing required by
          the HSR Act or any Foreign Competition Laws;

               (iii) in  determining  whether any action by or in respect of, or
          filing with,  any  Governmental  Authority  or other third  party,  is
          required, or any Approvals are required to be obtained from parties in
          connection  with the  consummation  of the  transactions  contemplated
          hereby;

               (iv) in seeking any  Approvals or making any  filings,  including
          furnishing  information  required in connection  therewith or with the
          Registration  Statement or the Proxy Statement,  and seeking timely to
          obtain any such Approvals, or making any filings;

               (v) in  connection  with the  listing  on the NYSE of the  Parent
          Common Stock to be issued in the Merger; and

               (vi) in order  to  facilitate  the  achievement  of the  benefits
          reasonably anticipated from the Merger.

         (d) The  Company  shall use its  reasonable  best  efforts to cause its
Affiliates and other Persons to transfer and assign all rights necessary for the
Company  to  continue  to  conduct  its  business   consistent  with  historical
operations and as currently conducted, pursuant to documentation and in a manner
reasonably acceptable to Parent.

                  5.5      Stock Options and Stock Plan; Options

         (a) At the Effective Time, each Outstanding  Employee  Option,  whether
vested or unvested,  will be assumed by Parent.  Each such Outstanding  Employee
Option so assumed by Parent under this Agreement  shall continue to have, and be
subject to, the same terms and conditions set forth in the Option Plans,  option
agreements thereunder and other relevant documentation  immediately prior to the
Effective Time, except that such Outstanding Employee Option will be exercisable
solely  for that  number of whole  shares of Parent  Common  Stock  equal to the
product of the number of shares of Company  Common  Stock that were  purchasable
under such Outstanding Employee Option immediately prior to the Effective Time

                                    43






multiplied  by the Exchange  Ratio,  rounded down to the nearest whole number of
shares of Parent Common Stock,  and the per-share  exercise price for the shares
of Parent  Common  Stock  issuable  upon  exercise of such  assumed  Outstanding
Employee  Option  will be equal  to the  quotient  determined  by  dividing  the
exercise  price per share of  Company  Common  Stock at which  such  Outstanding
Employee Option was exercisable  immediately  prior to the Effective Time by the
Exchange  Ratio,  and rounding the  resulting  exercise  price up to the nearest
whole cent.

         (b) Parent shall reserve for issuance a sufficient  number of shares of
Parent Common Stock for delivery upon exercise of Outstanding  Employee  Options
assumed by Parent under this Agreement. Parent shall file as soon as practicable
after  the  Effective  Date a  registration  statement  on Form  S-8  under  the
Securities  Act covering the shares of Parent  Common  Stock  issuable  upon the
exercise  of the  Outstanding  Employee  Options  assumed by Parent  pursuant to
Section 5.5(a),  and shall use its reasonable efforts to cause such registration
statement to become  effective as soon thereafter as practicable and to maintain
such  registration  in effect until the exercise or  expiration  of such assumed
Outstanding Employee Options.

         (c)  The  vesting  of  each  Outstanding   Employee  Option  shall  not
accelerate as a result of, or in connection with, the transactions  contemplated
hereby,  except to the extent required by the existing terms of the 1995 Plan or
option  agreement  pursuant to which it was granted.  In  addition,  the Company
shall  ensure that no  discretion  is exercised by the Board of Directors or any
committee  thereof or any other body or Person so as to cause the vesting of any
Outstanding  Employee  Option or any other warrant or right to acquire shares of
Company Common Stock to accelerate.

         (d) On and after the date  hereof,  the  Company  shall  ensure that no
offerings are made with respect to the Purchase Plan,  that no employee  payroll
deductions  are allowed under the Purchase Plan, and that no options to purchase
Company  Common  Stock shall be granted (or to be  granted)  under the  Purchase
Plan.

                  5.6      Employee Benefits.

         (a) Parent agrees that  individuals  who are employed by the Company or
any  Subsidiary of the Company  immediately  prior to the  Effective  Time shall
become employees of the Surviving  Corporation or one of its  Subsidiaries  upon
the  Effective  Time  (each such  employee,  a  "Company  Employee");  provided,
however, that this Section 5.6(a) shall not be construed to limit the ability of
the  Company or any of its  Subsidiaries  to  terminate  the  employment  of any
Company Employee at any time.

         (b) After the Effective Time and on a schedule  determined by Parent in
connection  with its  integration of its business with that of the Company,  the
Company Employees shall be eligible to participate in the employee benefit plans
of  Parent to the same

                                    44






extent as any similarly situated and geographically  located employee of Parent.
The  Company Employees will be allowed credit for their service with the Company
and its Subsidiaries for purposes of vesting, calculating the number of vacation
days to  which  such  employees  are  entitled,  subject  to a  maximum  of five
incremental days of vacation,  and  participation  only (and not for entitlement
(except as provided with respect to vacation) or benefit accrual purposes), with
respect to the  employee  benefit  plans in which  such  Company  Employees  are
allowed by Parent to participate following the Effective Time.

         (c) If requested by Parent in writing prior to the Effective  Time, the
Company shall cause to be adopted prior to the Effective Time resolutions of the
Company's  Board  of  Directors  to  cease  all  contributions  to the  Anatolia
Retirement  Savings Plan (the "401(k) Plan"),  and to terminate the 401(k) Plan,
immediately  prior to the Effective Time. Such resolutions shall provide (to the
extent  required under Section 411 of the Code) that all  participants  shall be
fully vested in their account  balances under the 401(k) Plan. Such  resolutions
shall also authorize  distributions  of 401(k) Plan balances to participants (to
the  extent  permitted  under  Section  401(k)  (10)  of the  Code)  as  soon as
practicable following the Company's receipt from the Internal Revenue Service of
a favorable  determination  letter  regarding  the  tax-qualified  status of the
401(k) Plan  following its  termination.  The Company shall deliver to parent an
executed  copy  of such  resolutions  as soon  as  practicable  following  their
adoption  by  Company's  Board of  Directors  and shall  fully  comply with such
resolutions.

                  5.7  Pooling; Reorganization.

         (a) The Company  shall not  knowingly  take,  or  knowingly  permit any
controlled  Affiliate of the Company to take,  any action that could prevent the
Merger from being treated (i) for financial accounting purposes as a "pooling of
interests"  under GAAP;  it being  understood  and agreed that if the  Company's
Accountants  advise the Company in writing that such an action would not prevent
the Merger from being so treated, such action will be conclusively deemed not to
constitute a breach of this Section 5.7 or (ii) as a "reorganization withing the
meaning of Section 368 of the Code.

         (b) The  Company  shall use its  reasonable  best  efforts to obtain an
executed  affiliate pooling agreement  substantially in the form attached hereto
as Exhibit C (each, a "Company  Affiliate  Pooling  Agreement") from each of the
Persons  identified  in  Section  2.24(d)  of the  Company  Disclosure  Schedule
concurrently  with the execution of this Agreement and thereafter from any other
person who may be deemed an affiliate of the Company  regarding  compliance with
Rule 145 under the Securities Act and the requirements for accounting  treatment
of the Merger as a "pooling of interests."

         (c) Parent shall not knowingly take or knowingly  permit any controlled
Affiliate of Parent to take, any action that could prevent the Merger from being
treated (i) for financial  accounting purposes as a "pooling of interests" under
GAAP;  it  being  understood

                                      45






and  agreed  that  if  Ernst  &  Young  LLP,  Parent's  independent  accountants
("Parent's  Accountants"),  advises  Parent in writing that such an action would
not prevent the Merger from being so treated,  such action will be  conclusively
deemed  not  to  constitute  a  breach  of  this  Section  5.7;  or  (ii)  as  a
"reorganization" within the meaning of Section 368 of the Code.

         (d)  Parent  shall use its  reasonable  efforts  to obtain an  executed
affiliate pooling agreement containing substantially the substance of the second
and third paragraphs of the Company Affiliate Pooling Agreement from each of the
Persons identified in Section 5.7(d) of the Parent Disclosure Schedule regarding
compliance  with the  requirements  for accounting  treatment of the Merger as a
"pooling of interests."

                  5.8  Notification of Certain Matters.

         (a) The Company  shall give prompt  notice to Parent,  and Parent shall
give prompt notice to the Company, of the occurrence, or non-occurrence,  of any
event the occurrence, or non-occurrence,  of which results in any representation
or  warranty  contained  in this  Agreement  to be untrue or  inaccurate  in any
material respect (or, in the case of any representation or warranty qualified by
its terms by materiality or Material  Adverse Effect,  then untrue or inaccurate
in any  respect)  and any failure of the  Company,  Parent or Merger Sub, as the
case may be, to comply with or satisfy in any  material  respect  any  covenant,
condition  or  agreement  to be  complied  with or  satisfied  by it  hereunder;
provided,  however, that the delivery of any notice pursuant to this Section 5.8
shall not limit or  otherwise  affect the  remedies  available  hereunder to the
party receiving such notice.

         (b) Each of the  Company  and Parent  shall give  prompt  notice to the
other of (i) any notice or other communication from any Person alleging that the
Approval of such Person is or may be required in  connection  with the Merger or
the  Related  Agreements,  (ii)  any  notice  or  other  communication  from any
Governmental  Authority in connection with the Merger or the Related Agreements,
(iii) any  Litigation,  relating to or  involving  or  otherwise  affecting  the
Company or its  Subsidiaries or Parent that relates to the Merger or the Related
Agreements; (iv) the occurrence of a default or event that, with notice or lapse
of time or both,  will  become a default  under any  Material  Agreement  of the
Company; and (v) any change that could reasonably be expected to have a Material
Adverse  Effect on the  Company  or  Parent or is likely to delay or impede  the
ability  of  either  Parent  or  the  Company  to  consummate  the  transactions
contemplated  by this  Agreement or the Related  Agreements  or to fulfill their
respective obligations set forth herein or therein.

the  transactions  contemplated  hereby or (iii)  required to prevent a Material
Adverse Effect on the Company or Parent from occurring.  If any party shall fail
to  obtain  any such  consent  from a third  Person,  such  party  shall use its
reasonable best efforts,  and will take any such actions reasonably requested by
the other  parties,  to limit the  adverse  effect  upon the Company and Parent,
their respective  Subsidiaries,  and their respective businesses  resulting,  or
which would result  after the  Effective  Time,  from the failure to obtain such
consent.

                  5.9  Listing on the New York Stock.  Exchange Parent shall use
its reasonable best efforts to cause the Parent Common Stock to be issued in the
Merger and pursuant to Parent's  options to be issued pursuant to Section 5.5 to
be approved  for listing on the NYSE,  subject to official  notice of  issuance,
prior to the Effective Time.

                  5.10   Public Announcements.  Parent  and  the  Company  shall
consult with and obtain the approval of the other party before issuing any press
release  or  other  public  announcement  with  respect  to the  Merger  or this
Agreement and shall not issue any such press release prior to such  consultation
and approval,  except as may be required by Law or any listing agreement related
to the trading of the shares of either party on any national securities exchange
or national  automated  quotation  system,  in which case the party proposing to
issue  such  press  release  or make  such  public  announcement  shall  use its
reasonable  best  efforts to consult in good faith with the other  party  before

                  5.11  Takeover Laws.  If any  form of  anti-takeover  statute,
Regulation or charter provision or Contract is or shall become applicable to the
Merger or the transactions contemplated hereby or by the Related Agreements, the
Company and the Board of Directors of the Company shall grant such Approvals and
take such actions as are  necessary  under such Laws and  provisions so that the
transactions  contemplated  hereby and thereby may be consummated as promptly as
practicable  on the terms  contemplated  hereby and thereby and otherwise act to
eliminate  or  minimize  the effects of such Law,  provision  or Contract on the
transactions contemplated hereby or thereby.

                  5.12  Accountant's Letters.

delivered to Parent a "comfort"  letter of the  Company's  Accountants,  dated a
date  within  two  business  days  before  the  date on which  the  Registration
Statement  shall become  effective and  addressed to Parent and the Company,  in
form and substance reasonably  satisfactory and customary in scope and substance
for letters  delivered by  independent  public  accountants  in connection  with
registration statements similar to the Form S-4.

         (b)  Parent  shall  use its  reasonable  best  efforts  to  cause to be
delivered to the Company a "comfort" letter of Parent's Accountants dated a date
within two  business  days

                                      47






before the date on which the  Registration  Statement shall become effective and
addressed  to  Parent  and  the  Company,  in  form  and  substance   reasonably
satisfactory  and  customary  in scope and  substance  for letters  delivered by
independent  public  accountants  in  connection  with  registration  statements
similar to the Form S-4.

                  5.13  Indemnification; Directors and Officer Insurance.

         (a) All rights to  indemnification,  advancement of Litigation expenses
and  limitation  of personal  liability  existing in favor of the  directors and
officers of the Company and its  Subsidiaries  under the provisions  existing on
the date hereof in their  respective  certificates of  incorporation,  bylaws or
similar organizational  documents,  as well as related director  indemnification
agreements  in  accordance  with their terms in  existence  on the date  hereof,
shall,  with  respect to any matter  existing  or  occurring  at or prior to the
Effective Time  (including the  transactions  contemplated  by this  Agreement),
survive the Effective Time for a period of not less than six years.

         (b) Parent shall cause to be maintained  for a period of six years from
the Effective Time the Company's current directors and officers insurance policy
(the  "Company's  D&O  Insurance")  to the extent that it provides  coverage for
events  occurring  prior to the Effective Time for all Persons who are directors
and officers of the Company on the date of this Agreement, so long as the annual
premium  therefor would not be in excess of 150% of the last annual premium paid
prior to the date of this Agreement (such amount, the "Maximum  Premium").  Upon
request by Parent,  the Company shall use its reasonable  best efforts to extend
coverage  under the  Company's  D&O  Insurance by obtaining a three-year  "tail"
policy  (provided,  that the lump sum payment to purchase such coverage does not
exceed  three times the Maximum  Premium) and such "tail"  policy shall  satisfy
Parent's obligations under this Section 5.13(b). Parent's obligations under this
Section  5.13(b)  shall also be  satisfied  if Parent's  directors  and officers
insurance provides (or is amended to provide) substantially similar coverage for
events  occurring  prior to the Effective Time for Persons who are directors and
officers of the Company on the date of this Agreement. If the Company's existing
directors and officers insurance expires,  is terminated or canceled during such
three-year  period or a "tail" policy cannot be purchased on the terms set forth
above and Parent cannot or determines not to satisfy its obligations  under this
Section  5.13(b)  pursuant  to the  preceding  sentence,  Parent  shall  use its
reasonable  best efforts to cause to be obtained as much  directors and officers
insurance as can be obtained for the  remainder of such period for an annualized
premium not in excess of the Maximum  Premium,  on terms and  conditions no less
advantageous than the Company's D&O Insurance.  The Company represents to Parent
that the last annual  premium  paid prior to the date of this  Agreement  is not
greater than $500,000.

         (c) The  provisions  of this  Section  5.13 are  intended to be for the
benefit of, and shall be enforceable by, each Person entitled to indemnification
hereunder and the heirs and representatives of such Person.


                                     48






                  5.14   Stockholders  Agreement.  The  Company  shall  use  its
reasonable  best  efforts,  on behalf of Parent and  pursuant  to the request of
Parent, to cause each Stockholder of the Company named on the signature pages to
the Stockholders  Agreement to execute and deliver to Parent,  concurrently with
the execution of this Agreement, and to comply with, the Stockholders Agreement.

necessary to effectuate the provisions of such Stockholders Agreement.

                  5.15   Option Agreement.  Contemporaneously with the execution
and delivery of this Agreement,  the Company shall deliver to Parent an executed
version of the Option  Agreement.  The  Company  agrees to fully  perform to the
fullest extent permitted under  applicable Law its obligations  under the Option
Agreement.

                  5.16  Release Agreements. The Company shall use its reasonable
best  efforts,  on behalf of Parent and  pursuant to the  request of Parent,  to
cause each of the Persons  identified  in Section 5.16 of the Parent  Disclosure
Schedule  to  execute  and  deliver  to Parent,  and to comply  with,  a release
agreement in the form of Exhibit D attached  hereto (the  "Release  Agreements")
prior to the Effective Time,  providing for, among other things,  release of the
Company,  Parent and the Surviving  Corporation and their respective  Affiliates
from any and all  claims,  known and  unknown,  that such Person has or may have
against such Persons through the Effective Time.

                  5.17    Optionholder  Letters.   The  Company  shall  use  its
reasonable best efforts to cause each of the Persons  identified in Section 5.17
of  the  Parent   Disclosure   Schedule   to  execute   and  deliver  a  written
acknowledgment, in form and substance satisfactory to Parent, acknowledging that
the options to purchase  Company  Common Stock issued to such Person were issued
at the times  and in the  amounts  set forth  below  such  Persons  name in such
Section  5.17,  notwithstanding  anything  contained  in the  option  agreements
relating to such options or contained in the Company's or such Person's records.

Section,  subsection,  Schedule or Exhibit to this  Agreement  unless  otherwise

shall be deemed in each case to be followed by the words  "without  limitation."
The word "herein" and similar  references mean,  except where a specific Section
or Article  reference is expressly  indicated,  the entire Agreement rather than
any  specific  Section  or  Article.  The  table of  contents  and the  headings
contained in this Agreement are for reference purposes only and shall not affect
in any way the meaning or interpretation of this Agreement.

                  8.6  Severability. If any  term  or  other  provision  of this
Agreement is invalid, illegal or incapable of being enforced by any rule of Law,
or public policy,  all other  conditions and provisions of this Agreement  shall
nevertheless  remain in full force and effect so long as the  economic  or legal
substance of the transactions  contemplated hereby is not affected in any manner
adverse to any party. Upon such  determination  that any term or other provision
is invalid,  illegal or incapable of being  enforced,  the parties  hereto shall
negotiate  in good faith to modify this  Agreement  so as to effect the original
intent of the parties as closely as possible in an acceptable  manner to the end
that transactions contemplated hereby are fulfilled to the extent possible.

                  8.7     Entire Agreement.   This  Agreement  and  the  Related
Agreements (including  all exhibits and schedules  hereto and thereto) and other
documents and instruments delivered in


                                     61






connection  herewith  constitute  the entire  agreement and supersedes all prior
agreements and undertakings  (other than the  Confidentiality  Agreement),  both
written and oral, among the parties, or any of them, with respect to the subject
matter hereof and thereof.

                  8.8  Assignment.  This  Agreement shall  not  be  assigned  by
operation of Law or otherwise,  except that Parent and Merger Sub may assign all
or any of  their  rights  hereunder  to any  Affiliate,  provided,  that no such
assignment shall relieve the assigning party of its obligations hereunder.

                  8.9  Parties in Interest. This Agreement shall be binding upon
and inure solely to the benefit of each party hereto,  and,  except as set forth
in Section 5.13, nothing in this Agreement,  express or implied,  is intended to
or shall confer upon any other Person any right, benefit or remedy of any nature
whatsoever under or by reason of this Agreement.

                  8.10 Failure or Indulgence Not Waiver; Remedies Cumulative. No
failure or delay on the part of any party  hereto in the  exercise  of any right
hereunder  will  impair  such  right  or be  construed  to be a  waiver  of,  or
acquiescence in, any breach of any representation, warranty or agreement herein,
nor will any single or partial  exercise  of any such  right  preclude  other or
further exercise thereof or of any other right. All rights and remedies existing
under this  Agreement are cumulative to, and not exclusive to, and not exclusive
of, any rights or remedies otherwise available.

                  8.11 Governing Law; Enforcement. This Agreement and the rights
and duties of the parties  hereunder  shall be  governed  by, and  construed  in
accordance  with,  the Law of the  State of New York.  The  parties  agree  that
irreparable  damage would occur in the event that any of the  provisions of this
Agreement or any Related  Agreement were not performed in accordance  with their
specific terms or were  otherwise  breached.  It is accordingly  agreed that the
parties shall be entitled to an injunction or injunctions to prevent breaches of
this Agreement or any Related  Agreement and to enforce  specifically  the terms
and  provisions  of this  Agreement  or any  Related  Agreement  in the  Federal
District Court for the Southern  District of New York, this being in addition to
any other  remedy to which they are  entitled at law or in equity.  In addition,
each of the  parties  hereto,  (a)  consents  to submit  itself to the  personal
jurisdiction of the Federal District Court for the Southern District of New York
in the event any dispute arises out of this  Agreement or any Related  Agreement
or any transaction  contemplated hereby or thereby,  (b) agrees that it will not
attempt to deny or defeat such personal  jurisdiction by motion or other request
for leave  from any such  court,  (c)  agrees  that it will not bring any action
relating  to  this  Agreement  or  any  Related  Agreement  or  any  transaction
contemplated  hereby or thereby in the Federal  District  Court for the Southern
District  of New York and (d) waives any right to trial by jury with  respect to
any action related to or arising out of this  Agreement or Related  Agreement or
any transaction contemplated hereby or thereby.

on any  applicable  record date to, from time to time, at the request of Parent,
at any meeting  (whether  annual or special and whether or not an  adjourned  or
postponed  meeting)  of  stockholders  of the  Company,  however  called,  or in
connection with any written consent of the holders of Company Common Stock,  (a)
if a meeting is held, appear at such meeting or otherwise cause the Shares to be
counted as present thereat for purposes of  establishing a quorum,  and (b) vote
or  consent  (or cause to be voted or  consented),  in  person or by proxy,  all
Shares,  and any  other  voting  securities  of the  Company  (whether  acquired
heretofore or hereafter) that are  beneficially  owned or held of record by such
Stockholder or as to which such  Stockholder  has,  directly or indirectly,  the
right to vote or direct the voting, in favor of the approval and adoption of the
Merger Agreement, the Merger and any action required in furtherance thereof.

                  1.2 Grant of Proxy.  In  furtherance  and not in limitation of
the foregoing,  each Stockholder hereby grants to, and appoints, Parent and each
of J. Michael  Kelly and Paul T.  Cappuccio in their  respective  capacities  as
officers of Parent,  and any individual who shall hereafter  succeed to any such
officer of Parent, and any other designee of Parent,  each of them individually,
its irrevocable proxy and attorney-in-fact  (with full power of substitution and
resubstitution)  to vote  the  Shares  as  indicated  in this  Article  I.  Each
Stockholder  intends this proxy to be  irrevocable  and coupled with an interest
and will take such further  action and execute such other  instruments as may be
necessary  to  effectuate  the intent of this  proxy.  Each  Stockholder  hereby
revokes any and all previous proxies with respect to such  Stockholder's  Shares
or any other voting securities of the Company that relate to the approval of the
Merger Agreement.

                  1.3 No Ownership Interest. Nothing contained in this Agreement
shall be deemed to vest in Parent any direct or indirect  ownership or incidence
of  ownership  of or with  respect to any  Shares.  All  rights,  ownership  and
economic  benefits of and  relating  to the Shares  shall  remain  vested in and
belong to the  Stockholders,  and  Parent  shall  have no  authority  to manage,
direct,  superintend,  restrict,  regulate,  govern,  or  administer  any of the
policies or  operations  of the Company or exercise  any power or  authority  to
direct the Stockholders in the voting of any of the Shares,  except as otherwise
provided  herein,  or  in  the  performance  of  the  Stockholders'   duties  or
responsibilities as stockholders of the Company.

                  1.4 Evaluation of Investment.  Each Stockholder,  by reason of
its knowledge and experience in financial and business matters,  believes itself
capable of evaluating the merits and risks of the investment in shares of Parent
Common Stock contemplated by the Merger Agreement.

                  1.5 Documents Delivered. Each Stockholder acknowledges receipt
of copies


                                      A-2





of the  following  documents:  (a) the Merger  Agreement  and all  exhibits  and
schedules  thereto,  (b) the Option Agreement,  (c) the Distribution  Agreement,
dated as of the date hereof, between Parent and the Company, (d) Parent's Annual
Report on Form 10-K for the fiscal year ended June 30, 1999,  (e) Parent's Proxy
Statement  dated  September 22, 1999,  and (f) each report filed with the SEC by
Parent  on Forms  8-K and  10-Q  since  June 30,  1999.  Each  Stockholder  also
acknowledges that such Stockholder possesses all the information relating to the
Company which such Stockholder deems relevant or material to such  Stockholder's
investment  in Parent  Common  Stock  should the Merger be  consummated  and its
entering into this Agreement.

                  1.6  No  Inconsistent  Agreements.   Each  Stockholder  hereby
covenants  and agrees that,  except as  contemplated  by this  Agreement and the
Merger  Agreement,  the Stockholder (a) has not entered,  and shall not enter at
any time while this Agreement  remains in effect,  into any voting  agreement or
voting trust with  respect to the Shares and (b) has not granted,  and shall not
grant at any time while this  Agreement  remains in effect,  a proxy or power of
attorney with respect to the Shares,  in either case, which is inconsistent with
such Stockholder's obligations pursuant to this Agreement.

the HSR Act, none of the execution, delivery or performance of this Agreement by

hereby nor compliance by it with any of the  provisions  hereof will (i) require
any filing with, or Approval of, any  Governmental  Authority,  (ii) result in a
violation  or breach of, or  constitute  (with or without due notice or lapse of
time or both) a default  (or give rise to any right of  termination,  amendment,

hereof,  and  sole  power  to  agree  to all of the  matters  set  forth in this
Agreement,  in each case with respect to all of such Stockholder's Shares on the
Closing  Date,  with no  limitations,  qualifications  or  restrictions  on such
rights,  subject to  applicable  federal  securities  laws and the terms of this
Agreement. Such Stockholder has good and marketable title to its Existing Shares
and at all times  during the term hereof and on the Closing  Date will have good
and  marketable  title to its  Shares,  free and clear of all Liens,  and,  upon
delivery  thereof to Merger Sub against delivery of the  consideration  therefor
pursuant to the Merger  Agreement,  good and marketable title thereto,  free and
clear of all Liens  (other  than any  arising  as a result of  actions  taken or
omitted by Merger Sub), will pass to Merger Sub.

                  2.4 No Finder's Fees. Except as previously disclosed to Parent
in writing, no broker,  investment banker,  financial advisor or other Person is
entitled to any broker's,  finder's, financial advisor's or other similar fee or

based upon arrangements made by or on behalf of such Stockholder.

               2.5 No Group. Each Stockholder is acting individually and not
as part of a "group" as defined in the Exchange Act.

                                 OTHER COVENANTS

                  3.1      Further Agreements of Stockholders.

                  (a)  Each  Stockholder,  severally  and  not  jointly,  hereby
agrees,  while this Agreement is in effect,  and except as contemplated  hereby,
not to sell, transfer, pledge, encumber, assign or otherwise dispose of, enforce
or permit the execution of the provisions of


                                      A-4

Shares,  any Shares acquired after the date hereof,  any securities  exercisable
for or  convertible  into  Company  Common  Stock or any  interest in any of the
foregoing,  except  for  sales  completed  earlier  than  30 days  prior  to the
Effective Time.

                  (b) Each Stockholder shall not request that the Company or its
transfer  agent   register  the  transfer   (book-entry  or  otherwise)  of  any
certificate or uncertificated  interest  representing any of such  Stockholder's
Shares,  and hereby  consents to the entry of stop transfer  instructions by the
Company of any transfer of such  Stockholder's  Shares,  unless such transfer is
made in compliance with this Agreement.

                  (c) In the event of a stock dividend or  distribution,  or any
change  in the  Company  Common  Stock  by  reason  of  any  stock  dividend  or
distribution,  or any change in the Company  Common Stock by reason of any stock
dividend,  split-up,  recapitalization,  combination,  exchange of shares or the
like,  the term  "Shares"  shall be deemed to refer to and include the Shares as
well as all such stock dividends and  distributions and any shares into which or

shall be entitled to receive any cash  dividend  paid by the Company  during the
term of this Agreement  until the Shares are canceled in the Merger or purchased
hereunder.

                  (d) Each  Stockholder  shall not,  nor shall it  authorize  or
permit any Affiliate,  director,  officer,  employee,  or any investment banker,
attorney  or  other  advisor,  agent  or  representative  of,  such  Stockholder
(collectively,  the "Representatives") to, directly or indirectly,  (i) solicit,
facilitate,  initiate or encourage,  or take any action to solicit,  facilitate,
initiate or  encourage,  any  inquiries or  communications  or the making of any
proposal or offer that constitutes or may constitute an Acquisition Proposal, or
(ii)  participate or engage in any discussions or negotiations  with, or provide
any information to, or take any action with the intent to facilitate the efforts
of, any Person  concerning any possible  Acquisition  Proposal or any inquiry or
communication  which might be reasonably be expected to result in an Acquisition
Proposal.  From and after the date hereof,  each Stockholder  shall  immediately
cease and terminate,  and shall cause its  Representatives  to immediately cease
and cause to be terminated,  all existing  discussion or  negotiations  with any
Persons  conducted  heretofore  with  respect  to, or that could  reasonably  be
expected to lead to, an Acquisition Proposal.

                  (e) Each  Stockholder  covenants  and  agrees  with the  other
Stockholders  and for the benefit of the Company  (which  shall be a third party
beneficiary  of  this  Section  3.1(e))  to  comply  with  and  perform  all its
obligations under this Agreement.

                  (f)  From  and  after  the   Effective   Time,   each  of  the
Stockholders  waives,  agrees not to enforce and  releases  the Company from any

                                  MISCELLANEOUS

                  4.1  Termination.  This Agreement shall terminate and no party

         (b) If to any of the Stockholders, to it at the address set forth under
its name on the signature pages hereto or to such other address  as the party to
whom notice is to be given may have  furnished  to the other party in writing in
accordance  herewith.  All such notices or communications  shall be deemed to be
received (i) in the case of personal delivery,  nationally  recognized overnight
courier or registered  or certified  mail, on the date of such delivery and (ii)

receipt.

                  4.5 Interpretation. When a reference is made in this Agreement
to Sections,  subsections,  Schedules or Exhibits,  such reference shall be to a
Section,  subsection,  Schedule or Exhibit to this  Agreement  unless  otherwise
indicated.  The words  "include,"  "includes" and  "including"  when used herein
shall be deemed in each case to be followed by the words  "without  limitation."
The word "herein" and similar  references mean,  except where a specific Section
or Article  reference is expressly  indicated,  the entire Agreement rather than
any  specific  Section  or  Article.  The  table of  contents  and the  headings
contained in this Agreement are for reference purposes only and shall not affect
in any way the meaning or interpretation of this Agreement.

                  4.6  Severability.  If any  term or  other  provision  of this
Agreement is invalid, illegal or incapable of being enforced by any rule of Law,
or public policy,  all other  conditions and provisions of this Agreement  shall
nevertheless remain in full force and effect so long as the



                                      A-7






economic  or legal  substance  of the  transactions  contemplated  hereby is not
affected in any manner adverse to any party.  Upon such  determination  that any
term or other provision is invalid,  illegal or incapable of being enforced, the
parties  hereto shall  negotiate in good faith to modify this Agreement so as to
effect  the  original  intent  of the  parties  as  closely  as  possible  in an
acceptable manner to the end that transactions contemplated hereby are fulfilled
to the extent possible.

                  4.7  Entire  Agreement;  No Third  Party  Beneficiaries.  This
Agreement,  the Merger Agreement and the other Related Agreements constitute the
entire agreement and supersedes all prior agreements and  understandings  (other
than the  Confidentiality  Agreement),  both written and oral, among the parties
with respect to the subject  matter  hereof and thereof,  and is not intended to
confer  upon any Person  other than the  parties  hereto any rights or  remedies
hereunder.

                  4.8 Amendments;  Assignment. This Agreement may not be amended
except by written agreement by all the parties.  This Agreement shall be binding
upon and inure to the benefit of the parties and their respective successors and
permitted  assigns.  Neither this Agreement nor any of the rights,  interests or
obligations under this Agreement shall be assigned,  in whole or in part, by any
of the parties without the prior written  consent of the other parties,  and any
purported  assignment  without such consent shall be void;  provided that Parent
may assign its rights and obligations hereunder to any direct or indirect wholly
owned subsidiary of Parent without such consent.

                  4.9 Failure or Indulgence Not Waiver; Remedies Cumulative.  No
failure or delay on the part of any party  hereto in the  exercise  of any right
hereunder  will  impair  such  right  or be  construed  to be a  waiver  of,  or
acquiescence in, any breach of any representation, warranty or agreement herein,
nor will any single or partial  exercise  of any such  right  preclude  other or
further exercise thereof or of any other right. All rights and remedies existing
under this  Agreement are cumulative to, and not exclusive to, and not exclusive
of, any rights or remedies otherwise available.

                  4.10 Governing Law; Enforcement. This Agreement and the rights
and duties of the parties  hereunder  shall be  governed  by, and  construed  in
accordance  with,  the Law of the  State of New York.  The  parties  agree  that
irreparable  damage would occur in the event that any of the  provisions of this
Agreement  were not performed in accordance  with their  specific  terms or were
otherwise breached.  It is accordingly agreed that the parties shall be entitled
to an injunction or  injunctions  to prevent  breaches of this  Agreement and to
enforce  specifically  the terms and provisions of this Agreement in the Federal
District Court for the Southern  District of New York, this being in addition to
any other  remedy to which they are  entitled at law or in equity.  In addition,
each of the  parties  hereto,  (a)  consents  to submit  itself to the  personal
jurisdiction of the Federal District Court for the Southern District of New York
in the  event  any  dispute  arises  out of this  Agreement  or any  transaction
contemplated  hereby, (b) agrees that it will not attempt to deny or defeat such
personal  jurisdiction by motion or other request for leave from any such court,
(c) agrees that it will not bring any action relating to this


                                      A-8






Agreement  or any  transaction  contemplated  hereby in any court other than the
Federal District Court for the Southern  District of New York and (d) waives any
right to trial by jury with  respect to any action  related to or arising out of
this Agreement or any transaction contemplated hereby.

                  4.11  Counterparts.  This  Agreement may be executed in one or
more counterparts, and by the different parties hereto in separate counterparts,
each of which when  executed  shall be deemed to be an original but all of which
taken together shall constitute one and the same agreement.

                                                 to Agreement and Plan of Merger



                  STOCK  OPTION  AGREEMENT,  dated as of December  21, 1999 (the
"Agreement"),  between AMERICA ONLINE, INC., a Delaware corporation  ("Parent"),
and MAPQUEST.COM, INC., a Delaware corporation (the "Company").

                  WHEREAS,  Parent,  the Company  and MQ  Acquisition,  Inc.,  a
Delaware  corporation  and a wholly owned  subsidiary of Parent  ("Merger Sub"),
are,  concurrently  with the execution and delivery of this Agreement,  entering
into an Agreement  and Plan of Merger,  dated as of the date hereof (the "Merger
Agreement;" capitalized terms used without definition herein having the meanings
assigned to them in the Merger Agreement), pursuant to which the Merger Sub will
merger with and into the Company (the "Merger"); and

                  WHEREAS, as a condition to their willingness to enter into the
Merger  Agreement,  Parent and Merger Sub have required that the Company  agree,
and  believing it to be in the best  interests  of the Company,  the Company has
agreed,  among  other  things,  to grant to Parent the  Option  (as  hereinafter
defined) to purchase  shares of common stock,  par value $.001 per share, of the
Company  ("Company  Common  Stock") at a price per share  equal to the  Exercise
Price (as hereinafter defined).

                  NOW  THEREFORE,  in  consideration  of the  foregoing  and the
mutual representations,  warranties,  covenants and agreements herein contained,
and intending to be legally bound hereby, the parties hereto agree as follows:


                                    ARTICLE I

                            OPTION TO PURCHASE SHARES

                  1.1      Grant of Option.

                  (a) The Company hereby grants to Parent an irrevocable  option
to  purchase,  in  whole  or in  part,  an  aggregate  of up to  3,571,661  duly
authorized,  validly  issued,  fully  paid and  nonassessable  shares of Company
Common Stock (representing 10% of the outstanding shares of Company Common Stock
as of the date  hereof)  on the terms and  subject to the  conditions  set forth
herein (the "Option");  provided,  however, that in no event shall the number of
shares of Company Common Stock for which this Option is  exercisable  exceed 10%
of the issued and  outstanding  shares of  Company  Common  Stock at the time of
exercise  without  giving  effect  to the  issuance  of any  Option  Shares  (as
hereinafter  defined).  The number of shares of Company Common Stock that may be
received  upon the exercise of the Option and the Exercise  Price are subject to
adjustment as herein set forth.


                                      B-1





                  (b) In the event that any additional  shares of Company Common
Stock  are  issued  or  otherwise  become  outstanding  after  the  date of this
Agreement  (other than pursuant to this  Agreement and other than pursuant to an
event  described in Section 3.1 hereof),  the number of shares of Company Common
Stock  subject to the Option shall be increased  so that,  after such  issuance,
such number together with any shares of Company Common Stock  previously  issued
pursuant hereto, equals 10% of the number of shares of Company Common Stock then
issued and  outstanding  without  giving effect to any shares  subject or issued
pursuant to the Option. Nothing contained in this Section 1.1(b) or elsewhere in
this Agreement  shall be deemed to authorize the Company to breach any provision
of the Merger  Agreement.  As used herein,  the term "Option  Shares"  means the
shares of Company Common Stock issuable pursuant to the Option, as the number of
such shares shall be adjusted pursuant to the terms hereof.

                  1.2      Exercise of Option.

                  (a) The Option  may be  exercised  by  Parent,  in whole or in
part, at any time, or from time to time,  commencing  upon the Exercise Date and
prior to the Expiration Date. As used herein, the term "Exercise Date" means the
date on which Parent becomes entitled to receive the Termination Fee pursuant to
Section 7.3(b) of the Merger  Agreement.  As used herein,  the term  "Expiration
Date" means the first to occur prior to Parent's exercise of the option pursuant
to Section 1.2(b) of:

                  (i) the Effective Time;

                  (ii) written notice of termination of this Agreement by Parent
to  the  Company;

                  (iii)  the  termination  of  the  Merger  Agreement  under
circumstances where the Termination Fee could not become payable; or

                  (iv)  the  date  that  is  twelve  months  from  the  date  of
termination of the Merger Agreement.

Notwithstanding  the  termination  of the  Option,  Parent  shall be entitled to
purchase  those Option  Shares with respect to which it may have  exercised  the
Option in accordance with the terms hereof prior to the Expiration Date, and the
termination  of the Option will not affect any rights  hereunder  which by their
terms do not terminate or expire prior to or at the Expiration Date.

                  (b) In the event Parent wishes to exercise the Option,  Parent
shall send a written  notice to the Company of its  intention to so exercise the
Option (a "Notice"), specifying the number of Option Shares to be purchased (and
the denominations of the certificates,  if more than one), whether the aggregate
Exercise  Price will be paid in cash or by  surrendering a portion of the Option
in accordance with Section 1.3(b) or a combination thereof, and the place in the
United States, time and date of the closing of such purchase (the "Option

                                      B-2






Closing;" and the date of such Closing,  the "Option Closing Date"),  which date
shall not be less than two Business  Days nor more than ten  Business  Days from
the date on which a Notice is delivered; provided, that the Option Closing shall
be held only if (i) such  purchase  would  not  otherwise  violate  or cause the
violation of, any applicable material Law (including the HSR Act or the rules of
the National  Association of Securities Dealers,  Inc. (the "NASD")) and (ii) no
material Law or Order shall have been  promulgated,  enacted,  entered  into, or
enforced by any Court or Governmental  Authority which prohibits delivery of the
Option Shares, whether temporary,  preliminary or permanent;  provided, however,
that the parties hereto shall use their  reasonable best efforts to (x) make all
necessary  filings  and  obtain  all  Approvals  and to  comply  with  any  such
applicable  Law and (y) have any such Order vacated or  reversed).  In the event
the Option Closing is delayed  pursuant to clause (i) or (ii) above,  the Option
Closing  shall be within five  business  days  following  the  cessation of such
restriction,  violation,  Law or Order, as the case may be;  provided,  further,
that, notwithstanding any prior Notice, Parent shall be entitled to rescind such
Notice and shall not be obligated to purchase  any Option  Shares in  connection
with such exercise upon written notice to such effect to the Company.

                  (c) At any Option  Closing,  (i) the Company  shall deliver to
Parent all of the Option Shares to be purchased by delivery of a certificate  or
certificates  evidencing such Option Shares in the  denominations  designated by
Parent  in the  Notice,  and (ii) if the  Option  is  exercised  in part  and/or
surrendered in part to pay the aggregate  Exercise Price, the Company and Parent
shall execute and deliver an amendment to this  Agreement  reflecting the Option
Shares for which the Option has not been exercised and/or surrendered. If at the
time of issuance of any Option Shares  pursuant to an exercise of all or part of
the  Option  hereunder,  the  Company  shall  have  issued  any  rights or other
securities which are attached to or otherwise associated with the Company Common
Stock,  then each  Option  Share  issued  pursuant to such  exercise  shall also
represent such rights or other securities with terms  substantially  the same as
and at least as favorable to Parent as are provided under any shareholder rights
agreement  or similar  agreement  of the Company  then in effect.  At the Option
Closing,  Parent  shall  pay to the  Company  by wire  transfer  of  immediately
available  funds to an account  specified by the Company to Parent in writing at
least two  Business  Days  prior to the Option  Closing  an amount  equal to the
Exercise  Price  multiplied  by the number of Option  Shares to be purchased for
cash  pursuant to this  Article I;  provided  that the failure or refusal of the
Company to specify an account shall not affect the Company's obligation to issue
the Option Shares.

                  (d) Upon the  delivery  by Parent to the Company of the Notice
and the  tender  of the  applicable  aggregate  Exercise  Price  in  immediately
available funds or the requisite  portion of the Option,  Parent shall be deemed
to be the holder of record of the Option  Shares  issuable  upon such  exercise,
notwithstanding that the stock transfer books of the Company may then be closed,
that  certificates  representing  such  Option  Shares  may not then  have  been
actually  delivered to Parent, or the Company may have failed or refused to take
any action required of it hereunder. The Company shall pay all expenses that may
be payable in connection  with the  preparation,  issuance and delivery of stock
certificates  under  this  Section  1.2 in the name of Parent or its  designees,
stock certificates or a substitute option agreement in the name of the assignee,
transferee or designee of Parent and any filing fees and other expenses  arising
from the


                                      B-3





performance of the transactions  contemplated hereby,  including pursuant to the
HSR Act.

                  1.3 Payments.

                  (a) The  purchase  and sale of the Option  Shares  pursuant to
Section 1.2 of this  Agreement  shall be at a purchase price equal to $27.00 per
Share  (as such  amount  may be  adjusted  pursuant  to the  terms  hereof,  the
"Exercise Price"), payable at Parent's option in cash, by surrender of a portion
of the Option in accordance with Section 1.3(b), or a combination thereof.

                  (b) Parent may elect to purchase Option Shares  issuable,  and
pay some or all of the aggregate Exercise Price payable, upon an exercise of the
Option by  surrendering  a portion of the Option with  respect to such number of
Option  Shares as is determined  by dividing the (i)  aggregate  Exercise  Price
payable in respect of the number of Option Shares being purchased in such manner
by (ii) the  excess of the Fair  Market  Value (as  defined  below) per share of
Company  Common Stock as of the last trading day  preceding  the Option  Closing
Date over the per share  Exercise  Price.  The "Fair Market  Value" per share of
Company  Common Stock shall be (i) if the Company  Common Stock is listed on the
Nasdaq  National  Market  ("NASDAQ"),  national  securities  exchange  or  other
nationally  recognized exchange or trading system as of the Option Closing Date,
the  average of last  reported  sale  prices per share of Company  Common  Stock
thereon for the 10 trading days  immediately  preceding the Option Closing Date,
or (ii) if the Company  Common  Stock is not listed on the NASDAQ,  any national
securities exchange or other nationally recognized exchange or trading system as
of the Option  Closing  Date,  the amount  determined  by a mutually  acceptable
independent  investment  banking firm as the value per share the Company  Common
Stock  would have if  publicly  traded on a  nationally  recognized  exchange or
trading  system  (assuming  the  absence of  unusual  market  conditions  and no
discount for minority interest, illiquidity or restrictions on transfer.


                                   ARTICLE II

                         REPRESENTATIONS AND WARRANTIES

                  2.1  Representations  and Warranties of Parent.  Parent hereby
represents and warrants to the Company that any Option Shares acquired by Parent
upon  exercise  of the  Option  will  not be  taken  with a view  to the  public
distribution thereof and will not be transferred or otherwise disposed of except
in a transaction  registered or exempt from  registration  under the  Securities
Act.

                  2.2 Representations and Warranties of the Company. The Company
hereby represents and warrants to Parent as follows:

                  (a)  Due  Authorization;  Good  Standing.  The  execution  and
delivery of this Agreement and the consummation of the transactions contemplated
hereby (including the


                                      B-4





issuance and exercise of the Option)  have been duly and validly  authorized  by
the Board of Directors of the Company and no other corporate  proceedings on the
part of the Company are necessary to authorize  this  Agreement or to consummate
the transactions  contemplated  hereby. This Agreement has been duly and validly
executed and delivered by the Company and constitutes a legal, valid and binding
obligation of the Company,  enforceable  against the Company in accordance  with
its terms. The Company is a corporation duly organized,  validly existing and in
good  standing  under the laws of the State of  Delaware  and has all  requisite
corporate power and authority to execute and deliver this Agreement.

                  (b)  Option  Shares.  The  Company  has  taken  all  necessary
corporate and other action to authorize and reserve for issuance,  and to permit
it to issue,  the Option Shares and all  additional  shares or other  securities
which may be issued pursuant to Section 3.1 upon exercise of the Option, and, at
all times  from the date  hereof  until such time as the  obligation  to deliver
Option  Shares  hereunder  terminates,  will have  reserved  for  issuance  upon
exercise  of the Option the Option  Shares and such other  additional  shares or
securities,  if any. All of the Option Shares and all additional shares or other
securities  or property  which may be issuable  pursuant  to Section  3.1,  upon
exercise of the Option and issuance  pursuant hereto,  shall be duly authorized,
validly issued, fully paid and nonassessable,  shall be delivered free and clear
of all  Liens  of any  nature  whatsoever,  and  shall  not  be  subject  to any
preemptive or similar right of any Person.

                  (c) No Conflict;  Required Filings and Consents. The execution
and delivery by the Company of this  Agreement do not,  and the  performance  of
this  Agreement  shall not,  (i)  conflict  with or violate the  Certificate  of
Incorporation or Bylaws of the Company, (ii) conflict with or violate any Law or
Order in each case  applicable  to the  Company  or by which its  properties  or
assets is bound or  affected,  or (iii)  result in any breach or violation of or
constitute  a default  (or an event  that  with  notice or lapse of time or both
would  become a  default)  under,  or impair the  Company's  rights or alter the
rights or obligations of any third party under,  or give to others any rights of
termination,  amendment,  acceleration  or  cancellation  of,  or  result in the
creation of a Lien on any of the  properties  or assets of the Company  pursuant
to, any note, bond, mortgage,  indenture,  contract,  agreement, lease, license,
permit,  franchise or other  instrument  or obligation to which the Company is a
party or by which the Company or its  properties or assets is bound or affected,
except  in the case of  clause  (ii) or  (iii)  above,  for any such  conflicts,
breaches, violations, defaults or other occurrences that would not, individually
or in the aggregate,  reasonably be expected to have a Material  Adverse Effect.
The  execution  and  delivery by the Company of this  Agreement  do not, and the
performance  of this  Agreement  shall not,  require the Company to,  obtain any
Approval of any Person or Approval of, observe any waiting period imposed by, or
make any filing with or notification to, any Governmental Authority, domestic or
foreign,  except for compliance with  applicable  requirements of the Securities
Act,  the  Exchange  Act  and  Blue  Sky  Laws,  the   pre-Merger   notification
requirements of the HSR Act or Foreign  Competition Laws or where the failure to
obtain such  Approvals,  or to make such  filings or  notifications,  could not,
individually  or in the  aggregate,  reasonably  be  expected to have a Material
Adverse Effect.

                  (d) Takeover Laws.  The Board of Directors of the Company has,
prior to the date hereof, approved this Agreement,  the Merger Agreement and the
Merger  and the other  transactions  contemplated  hereby and  thereby  and such
approval is  sufficient to render  inapplicable  to this  Agreement,  the Merger
Agreement,  the  Merger  and any  other  transactions  contemplated  hereby  and
thereby,  the  restrictions of Section 203 of the DGCL. No Delaware law or other
takeover  statute  or  similar  Law  and  no  provision  of the  Certificate  of
Incorporation  or Bylaws of the Company or any  Material  Agreement to which the
Company is a party (a) would or would purport to impose restrictions which might
adversely affect or delay the  consummation of the transactions  contemplated by
this  Agreement,  or (b) as a result  of the  consummation  of the  transactions
contemplated  by this  Agreement,  the Company or the Surviving  Corporation  by
Parent or Merger  Sub (i)  would or would  purport  to  restrict  or impair  the
ability of Parent to vote or otherwise exercise the rights of a shareholder with
respect to  securities  of the  Company or any of its  Subsidiaries  that may be
acquired or  controlled  by Parent or (ii) would or would purport to entitle any
Person to acquire securities of the Company.


                                   ARTICLE III

                    ADJUSTMENT UPON CHANGES IN CAPITALIZATION

                  3.1 Adjustment Upon Changes in Capitalization.  In addition to
the  adjustment  in the  number of shares of  Company  Common  Stock that may be
purchased upon exercise of the Option pursuant to Section 1.1 of this Agreement,
the number of shares of Company  Common  Stock  that may be  purchased  upon the
exercise of the Option and the  Exercise  Price  shall be subject to  adjustment
from time to time as provided in this Section 3.1. In the event of any change in
the number of issued and outstanding shares of Company Common Stock by reason of
any stock dividend, split-up, merger, recapitalization, combination, conversion,
exchange  of  shares,  spin-off  or other  change in the  corporate  or  capital
structure  of the Company  which would have the effect of diluting or  otherwise
diminishing  Parent's rights hereunder,  the number and kind of Option Shares or
other securities  subject to the Option and the Exercise Price therefor shall be
appropriately adjusted so that Parent shall receive upon exercise (or, if such a
change occurs between  exercise and Option Closing,  upon Option Closing) of the
Option the number and kind of shares or other securities or property that Parent
would have  received in respect of the Option  Shares that Parent is entitled to
purchase  upon  exercise of the Option if the Option had been  exercised (or the
purchase thereunder had been consummated,  as the case may be) immediately prior
to such event or the record date for such event,  as  applicable.  The rights of
Parent  under this  Section  shall be in addition to, and shall in no way limit,
its  rights  against  the  Company  for  breach of any  provision  of the Merger
Agreement.


                                   ARTICLE IV

                               REGISTRATION RIGHTS

                  4.1 Registration of Option Shares Under the Securities Act.


                                      B-6





                  (a) If  requested  by Parent at any time and from time to time
after  receipt  by Parent of Option  Shares  (the  "Registration  Period"),  the
Company shall use its reasonable best efforts,  as promptly as  practicable,  to
effect the registration under the Securities Act and any applicable state law (a
"Demand  Registration")  of such number of Option Shares owned by or issuable to
Parent in accordance with the method of sale or other  disposition  contemplated
by Parent,  including  a "shelf"  registration  statement  under Rule 415 of the
Securities Act or any successor provision, and to obtain all consents or waivers
of other  parties  that are  required  therefor.  Except with  respect to such a
"shelf" registration,  the Company shall keep such Demand Registration effective
for a period of not less than nine  months,  unless,  in the written  opinion of
counsel to the  Company,  which  opinion  shall be delivered to Parent and which
shall be  satisfactory  in form and  substance to Parent and its  counsel,  such
registration  under the Securities Act is not required in order to lawfully sell
and  distribute  such Option Shares in the manner  contemplated  by Parent.  The
Company  shall only have the  obligation  to effect  four  Demand  Registrations
pursuant  to this  Section  4.1;  provided,  that only  requests  relating  to a
registration  statement that has become effective under the Securities Act shall
be counted for purposes of determining the number of Demand  Registrations made.
The Company  shall be entitled  to  postpone  for up to 90 days from  receipt of
Parent's  request  for a Demand  Registration  the  filing  of any  registration
statement  in  connection  therewith  if the Board of  Directors  of the Company
determines in its good faith reasonable  judgment,  that such registration would
materially  interfere  with or  require  premature  disclosure  of,  and  have a
material adverse effect on, any material  acquisition,  reorganization  or other
transaction  involving the Company or any other  material  contract under active
negotiation by the Company;  provided, that the Company shall not have postponed
any Demand Registration pursuant to this sentence during the twelve month period
immediately  preceding  the date of delivery  of  Parent's  request for a Demand
Registration.

                  (b) If the Company effects a registration under the Securities
Act of Company Common Stock for its own account or for any other stockholders of
the Company (other than on Form S-4 or Form S-8, or any successor form),  Parent
shall  have the  right  to  participate  in such  registration  (an  "Incidental
Registration"  and,  together  with a Demand  Registration,  a  "Registration");
provided,  however,  that, if the managing  underwriters of such offering advise
the  Company in writing  that in their  opinion  the number of shares of Company
Common Stock  requested to be included in such Incidental  Registration  exceeds
the number which can be sold in such offering, the Company shall include therein
(i) first all shares  proposed  to be  included  therein by the Company and (ii)
second the shares  requested to be included  therein by Parent pro rata with the
shares intended to be included therein by any other  stockholder of the Company.
Participation  by Parent in any  Incidental  Registration  shall not  affect the
obligation of the Company to effect Demand Registrations under this Section 4.1.
The Company may withdraw any  registration  under the  Securities Act that gives
rise to an Incidental Registration without the consent of Parent.

                  (c) In  connection  with  any  Registration  pursuant  to this
Section  4.1,  (i) the  Company  and  Parent  shall  provide  each other and any
underwriter  of  the  offering  with  customary   representations,   warranties,
covenants, indemnification and contribution obligations



                                      B-7





in connection with such Registration,  and (ii) the Company shall use reasonable
best  efforts to cause any Option  Shares  included in such  Registration  to be
approved for listing on NASDAQ or any national  securities  exchange  upon which
the  Company's  securities  are then  listed,  subject  to  official  notice  of
issuance,  which notice shall be given by the Company upon  issuance.  The costs
and  expenses  incurred  by the  Company  in  connection  with any  Registration
pursuant  to  this  Section  4.1   (including  any  fees  related  to  Blue  Sky
qualifications and SEC filing fees) (the "Registration Expenses") shall be borne
by the  Company,  excluding  legal fees of  Parent's  counsel  and  underwriting
discounts  or  commissions  with  respect to Option  Shares to be sold by Parent
included in a Registration.


                                    ARTICLE V

                      REPURCHASE RIGHTS; SUBSTITUTE OPTIONS

                  5.1      Repurchase Rights.

                  (a)  Subject  to  Section  6.1,  at any time on or  after  the
Exercise Date and prior to the Expiration Date, Parent shall have the right (the
"Repurchase  Right") to require  the Company to  repurchase  from Parent (i) the
Option or any part  thereof as Parent  shall  designate  at a price (the "Option
Repurchase Price") equal to the amount, subject at the sole discretion of Parent
to clause  (iii) of  Section  6.1(a),  by which (A) the  Market/Offer  Price (as
defined  below)  exceeds (B) the  Exercise  Price,  multiplied  by the number of
Option Shares as to which the Option is to be  repurchased  and (ii) such number
of the Option  Shares as Parent shall  designate  at a price (the "Option  Share
Repurchase  Price") equal to the Market/Offer  Price multiplied by the number of
Option  Shares so  designated.  The term  "Market/Offer  Price"  shall  mean the
highest of (i) the highest  price per share of Company  Common Stock  offered or
paid in any Acquisition Proposal or any acquisition by any Person or group, in a
single transaction or a series of related transactions, after the date hereof of
10% or more of the outstanding shares of capital stock of the Company,  (ii) the
highest  closing price for shares of Company  Common Stock during the 30 trading
days  immediately  preceding  the date Parent  gives the  Repurchase  Notice (as
hereinafter  defined),  or (iii) in the event of a sale of all or  substantially
all of the Company's assets, the sum of the net price paid in such sale for such
assets plus the current  market value of the remaining net assets of the Company
as determined  by a nationally  recognized  investment  banking firm selected by
Parent and reasonably acceptable to the Company, divided by the number of shares
of Company Common Stock issued and  outstanding at the time of such sale,  which
determination,  absent manifest  error,  shall be conclusive for all purposes of
this  Agreement.   In  determining  the   Market/Offer   Price,   the  value  of
consideration  other than cash shall be  determined  by a nationally  recognized
investment  banking firm  selected by Parent and  reasonably  acceptable  to the
Company, which determination, absent manifest error, shall be conclusive for all
purposes of this Agreement.

                  (b) Parent shall exercise its  Repurchase  Right by delivering
to the Company written notice (a "Repurchase Notice") stating that Parent elects
to require the


                                      B-8





Company to repurchase all or a portion of the Option and/or the Option Shares as
specified  therein.  The  closing  of  the  Repurchase  Right  (the  "Repurchase
Closing")  shall  take place in the  United  States at the place,  time and date
specified  in the  Repurchase  Notice,  which  date  shall  not be less than two
business  days  nor more  than  ten  business  days  from the date on which  the
Repurchase  Notice is  delivered.  At the  Repurchase  Closing,  subject  to the
receipt of a writing evidencing the surrender of the Option and/or  certificates
representing  Option  Shares,  as the case may be, the Company  shall deliver to
Parent the Option Repurchase Price therefor or the Option Share Repurchase Price
therefor,  as the case may be, or the  portion  thereof  that the Company is not
then prohibited under  applicable law and regulation from so delivering.  At the
Repurchase  Closing,  (i) the Company shall pay to Parent the Option  Repurchase
Price for the  portion of the Option  which is to be  repurchased  or the Option
Shares  Repurchase  Price for the number of Option Shares to be repurchased,  as
the case may be, by wire transfer of immediately  available  funds to an account
specified by Parent at least 24 hours prior to the  Repurchase  Closing and (ii)
if the Option is repurchased  only in part, the Company and Parent shall execute
and deliver an  amendment to this  Agreement  reflecting  the Option  Shares for
which the Option is not being repurchased.

                  (c) To  the  extent  that  the  Company  is  prohibited  under
applicable law or regulation from  repurchasing the portion of the Option or the
Option  Shares  designated  in  such  Repurchase   Notice,   the  Company  shall
immediately  so notify  Parent and  thereafter  deliver,  from time to time,  to
Parent  the  portion  of the  Option  Repurchase  Price  and  the  Option  Share
Repurchase Price, respectively, that it is no longer prohibited from delivering,
within  five  business  days after the date on which the Company is no longer so
prohibited; provided, however, that if the Company at any time after delivery of
a Repurchase Notice is prohibited under applicable Law from delivering to Parent
the full amount of the Option  Repurchase  Price and the Option Share Repurchase
Price for the Option or Option Shares to be  repurchased,  respectively,  Parent
may rescind the exercise of the Repurchase  Right,  whether in whole, in part or
to the extent of the prohibition,  and, to the extent rescinded,  no part of the
amounts,  terms or the rights  with  respect to the Option or  Repurchase  Right
shall be changed or affected as if such Repurchase Right was not exercised.

                  5.2      Substitute Option.

                  (a) In the event that the Company enters into an agreement (i)
to  consolidate  with or  merge  into  any  person,  other  than  Parent  or any
Subsidiary  of Parent  (each an "Excluded  Person"),  and the Company is not the
continuing or surviving  corporation of such  consolidation  or merger,  (ii) to
permit any Person,  other than an Excluded Person, to merge into the Company and
the Company shall be the continuing or surviving or acquiring corporation,  but,
in connection with such merger,  the then  outstanding  shares of Company Common
Stock shall be changed into or exchanged  for stock or other  securities  of any
other  Person or cash or any other  property or the then  outstanding  shares of
Company  Common  Stock shall after such  merger  represent  less than 50% of the
outstanding shares and share equivalents of the merged or acquiring company,  or
(iii) to sell or otherwise  transfer all or  substantially  all of its assets to
any Person,  other than an Excluded  Person,  then,  and in each such case,  the
agreement governing



                                      B-9





such transaction  shall make proper provision so that,  unless earlier exercised
by Parent,  the Option shall,  upon the consummation of any such transaction and
upon the terms and conditions set forth herein,  be converted into, or exchanged
for,  an option (the  "Substitute  Option")  for  Substitute  Option  Shares (as
hereinafter  defined),  at the election of Parent,  of either (x) the  Acquiring
Corporation  (as  hereinafter  defined)  or (y) any  Person  that  controls  the
Acquiring Corporation.

                  (b) The  Substitute  Option  shall  have the same terms as the
Option;  provided,  however,  that if the terms of the Substitute Option cannot,
because of  applicable  Law, be the same as the  Option,  such terms shall be as
similar as possible and in no event less advantageous to Parent than the Option.
The issuer of the Substitute Option shall enter into an agreement with Parent in
substantially the same form and terms as this Agreement  (including the terms of
this  Article  V) to  memorialize  the  terms  of  the  Substitute  Option.  The
Substitute  Option shall be  exercisable  for such number of  Substitute  Option
Shares as is equal to the Market/Offer  Price multiplied by the number of shares
of Company Common Stock for which the Option was exercisable  immediately  prior
to the event described in the first sentence of Section  5.2(a),  divided by the
Average Price (as  hereinafter  defined).  The exercise  price of the Substitute
Option per  Substitute  Option Share shall then be equal to the  Exercise  Price
multiplied  by a fraction,  the numerator of which shall be the number of shares
of Company Common Stock for which the Option was exercisable  immediately  prior
to the  event  described  in the  first  sentence  of  Section  5.2(a)  and  the
denominator  of which shall be the number of Substitute  Option Shares for which
the Substitute Option is exercisable.

                  (c) In addition to any other  restrictions  or covenants,  the
Company  agrees  that it shall not enter or agree to enter into any  transaction
described in Section 5.2(a) unless the Acquiring Corporation and any Person that
controls the Acquiring  Corporation assume in writing all the obligations of the
Company  hereunder  and agree  for the  benefit  of  Parent to comply  with this
Article V.

                  (d) For purposes of this Section 5.2, the following terms have
the meanings indicated:

                  "Acquiring  Corporation"  shall  mean  (i) the  continuing  or
surviving  Person of a  consolidation  or merger with the Company (if other than
the Company), (ii) the Company in a consolidation or merger in which the Company
is the continuing or surviving or acquiring person,  and (iii) the transferee of
all or substantially all of the Company's assets.

                  "Substitute  Option  Shares"  shall mean the shares of capital
stock (or similar equity  interest) with the greatest voting power in respect of
the election of directors (or other persons similarly  responsible for direction
of the business and affairs) of a Person.

                  "Average  Price"  shall  mean the  average  closing  price per
Substitute

                                      B-10






Option Share, on the principal trading market on which such shares are traded as
reported by a nationally  recognized source, for the 30 trading days immediately
preceding the consolidation,  merger or sale in question, but in no event higher
than the closing price of the Substitute Option Shares on such market on the day
preceding such consolidation,  merger or sale; provided,  that if the Company is
the issuer of the  Substitute  Option,  the Average Price shall be computed with
respect to a share of common stock issued by the Person merging into the Company
or by any entity which  controls or is controlled by such person,  as Parent may
elect.


                                   ARTICLE VI

                                  MISCELLANEOUS

                  6.1      Total Profit.

                  (a) Notwithstanding any other provision of this Agreement,  in
no  event  shall  Parent's  Total  Profit  (as   hereinafter   defined)   exceed
$34,600,000,  less the amount of any  Termination  Fee paid  pursuant to Section
7.2(b) of the Merger  Agreement,  and, if it otherwise would exceed such amount,
Parent,  at its sole  election,  shall either (i) reduce the number of shares of
Company  Common Stock  subject to this  Option,  (ii) deliver to the Company for
cancellation  Option  Shares  previously  purchased  by Parent,  (iii) limit the
amount of the Option Repurchase Price or the Option Share Repurchase Price, (iv)
pay  cash to the  Company,  or (v) any  combination  thereof,  so that  Parent's
actually  realized  Total  Profit shall not exceed such amount after taking into
account the foregoing actions.

                  (b) As used  herein,  the term "Total  Profit"  shall mean the
aggregate  amount (before taxes) of the  following:  (i) the amount  received by
Parent  pursuant  to the  Company's  repurchase  of the Option  (or any  portion
thereof)  pursuant  to  Section  5.1,  (ii) (x) the  amount  received  by Parent
pursuant to the Company's  repurchase of Option Shares  pursuant to Section 5.1,
less (y) Parent's purchase price for such Option Shares,  (iii) (x) the net cash
amounts  received by Parent  pursuant to any consummated  arm's-length  sales of
Option  Shares  (or any other  securities  into  which  such  Option  Shares are
converted or exchanged) to any unaffiliated  party,  less (y) Parent's  purchase
price of such Option Shares, (iv) any amounts received by Parent pursuant to any
consummated arm's-length transfers of the Option (or any portion thereof) to any
unaffiliated  party, and (v) any amount equivalent to the foregoing with respect
to the Substitute Option.

                  6.2  Further  Assurances.  From  time to  time,  at the  other
party's  request and without  further  consideration,  each party  hereto  shall
execute and deliver such  additional  documents and take all such further action
as may be necessary or desirable to consummate the transactions  contemplated by
this  Agreement,  including,  without  limitation,  to vest in  Parent  good and
marketable  title,  free and clear of all Liens, to any Option Shares  purchased
hereunder.


                                      B-11






                  6.3 Division of Option;  Lost Options.  The Agreement (and the
Option  granted  hereby) are  exchangeable,  without  expense,  at the option of
Parent,  upon  presentation  and  surrender of this  Agreement at the  principal
office of the Company,  for other agreements  providing for Options of different
denominations  entitling the holder  thereof to purchase,  on the same terms and
subject to the same  conditions  as are set forth  herein,  in the aggregate the
same number of Option Shares purchasable hereunder.  Upon receipt by the Company
of evidence  reasonably  satisfactory to it of the loss, theft or destruction or
mutilation of this Agreement, and (in the case of loss, theft or destruction) of
reasonably satisfactory indemnification,  and upon surrender and cancellation of
this  Agreement,  if  mutilated,  the  Company  will  execute  and deliver a new
agreement of like tenor and date.


                  6.4      Certain Filings; Listing.

                  (a) If so requested by Parent, promptly after the date hereof,
the Company shall make all filings which are required  under the HSR Act and any
applicable  Law,  and the  parties  shall  furnish to each other such  necessary
information and reasonable assistance as may be requested in connection with the
preparation of filings and submissions to any Governmental Authority, including,
without  limitation,  filings  under  the  provisions  of the  HSR  Act  and any
applicable   Law.  The  Company   shall   supply   Parent  with  copies  of  all
correspondence,  filings  or  communications  (or  memoranda  setting  forth the
substance thereof) between the Company and its  representatives  and the Federal
Trade Commission, the Department of Justice and any other Governmental Authority
and members of their  respective  staff with respect to this  Agreement  and the
transactions contemplated hereby.

                  (b) If the Company Common Stock or any other  securities to be
acquired  upon exercise of the Option are then listed on NASDAQ (or any national
securities exchange or other nationally  recognized exchange or trading system),
the Company,  upon the request of parent,  will promptly file an  application to
list the shares of Company Common Stock or such other  securities to be acquired
upon  exercise of the Option on NASDAQ (and any such other  national  securities
exchange or other nationally recognized exchange or trading system) and will use
reasonable  best  efforts to obtain  approval  of such  listing as  promptly  as
practicable.

                  6.5  Notices.  All notices or other  communications  which are
required or permitted  hereunder shall be in writing and sufficient if delivered
personally or sent by nationally  recognized  overnight courier or by registered

mail,  with a copy  thereof  to be  delivered  or sent as  provided  above or by

                  6.6 Interpretation. When a reference is made in this Agreement
to Sections,  subsections,  Schedules or Exhibits,  such reference shall be to a
Section,  subsection,  Schedule or Exhibit to this  Agreement  unless  otherwise
indicated.  The words  "include,"  "includes" and  "including"  when used herein
shall be deemed in each case to be followed by the words  "without  limitation."
The word "herein" and similar  references mean,  except where a specific Section
or Article  reference is expressly  indicated,  the entire Agreement rather than
any  specific  Section  or  Article.  The  table of  contents  and the  headings
contained in this Agreement are for reference purposes only and shall not affect
in any way the meaning or interpretation of this Agreement.

                  6.7  Severability.  If any  term or  other  provision  of this
Agreement is invalid, illegal or incapable of being enforced by any rule of Law,
or public policy,  all other  conditions and provisions of this Agreement  shall
nevertheless  remain in full force and effect so long as the  economic  or legal
substance of the transactions  contemplated hereby is not affected in any manner
adverse to any party. Upon such  determination  that any term or other provision
is invalid,  illegal or incapable of being  enforced,  the parties  hereto shall
negotiate  in good faith to modify this  Agreement  so as to effect the original
intent of the parties as closely as possible in an acceptable  manner to the end
that transactions contemplated hereby are fulfilled to the extent possible.

                  6.8  Entire  Agreement;  No Third  Party  Beneficiaries.  This
Agreement  constitutes the entire  agreement and supersedes all prior agreements
and understandings, both written and oral, among the parties with respect to the
subject matter hereof,  and is not intended to confer upon any Person other than
the parties hereto any rights or remedies hereunder.

                  6.9 Amendments;  Assignment. This Agreement may not be amended
except by written agreement by all the parties.  This Agreement shall be binding
upon and inure to the benefit of the parties and their respective successors and
permitted  assigns.  Neither this Agreement nor any of the rights,  interests or
obligations under this Agreement shall be assigned,  in whole or in part, by any
of the parties without the prior written  consent of the other parties,  and any
purported assignment without such consent shall be void;  provided,  that Parent
may assign its rights and obligations hereunder to any direct or indirect wholly
owned subsidiary of Parent without such consent.

                  6.10 Failure or Indulgence Not Waiver; Remedies Cumulative. No
failure or delay on the part of any party  hereto in the  exercise  of any right
hereunder  will  impair  such  right  or be  construed  to be a  waiver  of,  or
acquiescence in, any breach of any representation, warranty or agreement herein,
nor will any single or partial  exercise  of any such  right  preclude  other or
further exercise thereof or of any other right. All rights and remedies existing
under this  Agreement are cumulative to, and not exclusive to, and not exclusive
of, any rights or remedies otherwise available.

                  6.11 Governing Law; Enforcement. This Agreement and the rights
and duties of the parties  hereunder  shall be  governed  by, and  construed  in
accordance with, the Law



                                      B-14





of the State of New York. The parties agree that irreparable  damage would occur
in the event that any of the  provisions of this Agreement were not performed in
accordance  with  their  specific  terms  or  were  otherwise  breached.  It  is
accordingly  agreed that the  parties  shall be  entitled  to an  injunction  or
injunctions to prevent  breaches of this  Agreement and to enforce  specifically
the terms and provisions of this Agreement in the Federal District Court for the
Southern  District of New York,  this being in  addition to any other  remedy to
which they are entitled at law or in equity.  In  addition,  each of the parties
hereto,  (a)  consents  to submit  itself to the  personal  jurisdiction  of the
Federal  District  Court for the Southern  District of New York in the event any
dispute arises out of this Agreement or any transaction contemplated hereby, (b)
agrees that it will not attempt to deny or defeat such personal  jurisdiction by
motion or other  request for leave from any such court,  (c) agrees that it will
not bring any action relating to this Agreement or any transaction  contemplated
hereby in any court  other  than the  Federal  District  Court for the  Southern
District  of New York and (d) waives any right to trial by jury with  respect to
any action  related  to or  arising  out of this  Agreement  or any  transaction
contemplated hereby.

                  6.12  Counterparts.  This  Agreement may be executed in one or
more counterparts, and by the different parties hereto in separate counterparts,
each of which when  executed  shall be deemed to be an original but all of which
taken together shall constitute one and the same agreement.

                               AFFILIATE AGREEMENT

                                December 21, 1999

America Online, Inc.
22000 AOL Way
Dulles, Virginia 20166

Ladies and Gentlemen:

                  The  undersigned has been advised that, as of the date hereof,
the  undersigned  may be deemed to be an  "affiliate" of  MapQuest.com,  Inc., a
Delaware  corporation (the  "Company"),  as that term is defined for purposes of
paragraphs  (c) and (d) of Rule 145 of the  Regulations  of the  Securities  and
Exchange  Commission  (the "SEC") under the  Securities  Act of 1933, as amended
(the "Securities Act").

                  Pursuant  to the terms and subject to the  conditions  of that
certain  Agreement  and Plan of Merger  by and among  America  Online,  Inc.,  a
Delaware corporation ("Parent"),  MQ Acquisition,  Inc., a newly formed Delaware
corporation  and a wholly owned  subsidiary of Parent  ("Merger  Sub"),  and the
Company, dated as of December 21, 1999 (the "Merger Agreement"),  providing for,
among  other  things,  the merger of Merger Sub with and into the  Company  (the
"Merger"), the undersigned will be entitled to receive shares of common stock of
Parent or options or  warrants  to acquire  Parent  Common  Stock  (collectively
"Parent  Common Stock") in exchange for shares of common stock of the Company or
options or warrants  to acquire  Company  Common  Stock  (collectively  "Company
Common  Stock") owned by the  undersigned at the Effective Time of the Merger as
determined  pursuant  to the Merger  Agreement.  Capitalized  terms used but not
defined herein are defined in the Merger  Agreement and are used herein with the
same meanings ascribed to them therein.

                  The  undersigned  understands  that the Merger will be treated
for financial accounting purposes as a "pooling of interests" in accordance with
GAAP and that the staff of the SEC has issued certain  guidelines that should be
followed to ensure the  application  of pooling of interests  accounting  to the
Merger.

                  In consideration of the agreements contained herein,  Parent's
reliance on this letter in connection  with the  consummation  of the Merger and
for other good and valuable consideration,  the receipt and sufficiency of which
are hereby acknowledged, the undersigned hereby agrees that the undersigned will
not make any sale, pledge, transfer or other disposition

                                      C-1






of, or hedge or reduce its risk with respect to, (i) Company Common Stock during
the period  from the 30th day prior to the  Effective  Time until the earlier of
the Effective  Time or the  termination  of the Merger  Agreement or (ii) Parent
Common  Stock now owned or  hereafter  acquired by the  undersigned,  including,
without  limitation,  Parent  Common  Stock to be  received  by the  undersigned
pursuant to the Merger,  until such time as financial statements that include at
least 30 days of combined  operations of the Company and Parent after the Merger
will have been publicly  reported,  unless the  undersigned  delivers to Parent,
prior to any such sale, transfer or other disposition, written advice from Ernst
& Young LLP,  independent  public accountants for Parent, or a written no-action
letter  from  the  accounting  staff  of the  SEC,  in  either  case in form and
substance  reasonably  satisfactory  to Parent,  to the  effect  that such sale,
transfer or other  disposition  will not cause the Merger not to be treated as a
"pooling of interests" for financial accounting purposes in accordance with GAAP
and the Regulations of the SEC.

                  The undersigned  has been advised that the offering,  sale and
delivery of the shares of Parent  Common Stock  pursuant to the Merger will have
been  registered  with  the  SEC  under  the  Securities  Act on a  Registration
Statement on Form S-4. The  undersigned  also has been advised,  however,  that,
because the  undersigned  may be deemed to be an Affiliate of the Company at the
time the Merger is  submitted  for a vote of the  stockholders  of the  Company,
Parent Common Stock  received by the  undersigned  pursuant to the Merger can be
sold by the undersigned only (i) pursuant to an effective registration statement
under  the  Securities  Act,  (ii) in  conformity  with  the  volume  and  other
limitations of Rule 145 promulgated by the SEC under the Securities Act or (iii)
in reliance  upon an exemption  from  registration  that is available  under the
Securities Act.

                  The  undersigned   also   understands   that  "stop  transfer"
instructions  will be given to the transfer  agent for the Company  Common Stock
with  respect  to  shares of the  Company  Common  Stock now owned or  hereafter
acquired by the  undersigned  and that there will be placed on the  certificates
representing such shares of Company Common Stock, or any substitutions therefor,
a legend stating in substance as follows:

"These  shares  may be  transferred  only in  accordance  with  the  terms of an
Affiliate  Agreement  between  the  original  holder of such  shares and America
Online,  Inc., a copy of which agreement is on file at the principal  offices of
Anatolia, Inc."

It is understood and agreed that the legend set forth above will be removed upon
surrender  of  certificates  bearing  such  legend  by  delivery  of  substitute
certificates  without such legend (i) if the undersigned  will have delivered to
Parent the above-referenced advice of Ernst & Young LLP, or the above-referenced
no-action  letter  from  the  accounting  staff  of the  SEC or  (ii)  upon  the
termination of the Merger Agreement.

                  The  undersigned   also   understands   that  "stop  transfer"
instructions  will be given to the transfer  agent for Parent  Common Stock with
respect to shares of Parent Common Stock now owned or hereafter  acquired by the
undersigned (other than shares of Parent Common Stock to


                                      C-2





be  received by the  undersigned  pursuant to the Merger) and that there will be
placed on the certificates  representing  such shares of Parent Common Stock, or
any substitutions therefor, a legend stating in substance as follows:

"These  shares  may be  transferred  only in  accordance  with  the  terms of an
Affiliate  Agreement  between  the  original  holder of such  shares and America
Online,  Inc., a copy of which agreement is on file at the principal  offices of
America Online, Inc."

It is understood and agreed that the legend set forth above will be removed upon
surrender  of  certificates  bearing  such  legend  by  delivery  of  substitute
certificates  without such legend (i) if the undersigned  will have delivered to
Parent the above-referenced  advice of Ernst & Young LLP or the above-referenced
no-action  letter  from  the  accounting  staff  of the  SEC or  (ii)  upon  the
termination of the Merger Agreement.

                  The  undersigned   also   understands   that  "stop  transfer"
instructions  will be given to the transfer  agent for Parent  Common Stock with
respect  to shares of Parent  Common  Stock to be  received  by the  undersigned
pursuant  to the  Merger  and that  there  will be  placed  on the  certificates
representing such shares of Parent Common Stock, or any substitutions  therefor,
a legend stating in substance as follows:

"These shares were issued in a transaction to which Rule 145  promulgated  under
the Securities Act of 1933, as amended, applies. These shares may be transferred
only in  accordance  with the  terms of such  Rule  and an  Affiliate  Agreement
between the original holder of such shares and America  Online,  Inc., a copy of
which agreement is on file at the principal offices of America Online, Inc."

It is understood and agreed that the legend set forth above will be removed upon
surrender  of  certificates  bearing  such  legend  by  delivery  of  substitute
certificates  without  such legend if the  undersigned  will have  delivered  to
Parent an opinion of counsel, in form and substance  reasonably  satisfactory to
Parent, to the effect that (i) the sale or disposition of the shares represented
by the  surrendered  certificates  may be effected  without  registration of the
offering,  sale and delivery of such shares under the  Securities  Act, (ii) the
shares to be so transferred may be publicly  offered,  sold and delivered by the
transferee  thereof without  compliance with the registration  provisions of the
Securities  Act and (iii) the  undersigned  will have  delivered  to Parent  the
above-referenced  advice of Ernst & Young LLP or the above-referenced  no-action
letter from the accounting staff of the SEC.

                  Parent agrees that it will not unreasonably  refuse to consent
to, or unreasonably delay, the removal of the foregoing legends.

                  By its execution  hereof,  Parent agrees that it will, as long
as  the  undersigned  owns  any  Parent  Common  Stock  to be  received  by  the
undersigned  pursuant to the Merger,  take all reasonable efforts to make timely
filings with the SEC of all reports required to be filed by it

                                      C-3






pursuant to the Exchange Act of 1934, as amended, and will promptly furnish upon
written  request of the  undersigned a written  statement  confirming  that such
reports have been so timely filed.
