          Contract is to be taken as including the maximum  bonus,  the standard
          bonus or no bonus;

     and shall authorise the UK Board to enter on the Savings Contract  proposal
     form such monthly savings contribution, not exceeding the maximum stated on
     the  application  form,  as shall be  determined  pursuant to Rule 4 below.
     Subject to the  aforesaid  the  invitation  may be given in such manner and
     form as the UK Board may from time to time prescribe.

3.4  Each application shall be deemed to be for an Option over the largest whole
     number of Plan  Shares  which can be bought at the  Option  Price  with the
     expected  repayment under the related  Savings  Contract at the appropriate
     Bonus Date.

3.5  Each application shall be valid only if:-

          discretion allow.

4.    Adjustment of Application

4.1  If the UK Company receives valid  applications for Option over an aggregate
     number of Plan  Shares  which would cause any of the limits in Rule 9 to be
     exceeded then the following steps shall be carried out  successively to the
     extent necessary to eliminate the excess:-

     (A)  each  election for the maximum  bonus to be included in the  repayment
          under the Savings  Contract shall be deemed to be an election for only
          the standard bonus to be so included;

     (B)  each  election for a bonus to be included in the  repayment  under the
          Savings  Contract  shall be deemed to be an election  for no bonus (or
          only part of the bonus) to be so included;

     (C)  the excess over(pound)5 of the monthly savings  contribution chosen by
          each applicant shall be reduced pro rata to the extent necessary; and

     (D)  applications shall be selected by lot, each based on a monthly savings
          contribution  of(pound)5  and the  inclusion of no bonus in the amount
          applied in the purchase of Shares.

4.2  Each  application  shall be deemed to have been  modified  o  withdrawn  in
     accordance  with the  application  of the foregoing  provisions  and the UK
     Board shall  complete  each Savings  Contract  proposal form to reflect any
     reduction in monthly savings contributions resulting therefrom.

5.   Deductions of SAYE Contributions

Contributions  to any  Savings  Contract  shall be  payable  by means of regular
deductions from the wage or salary remitted by the UK Company or a Subsidiary to
the Eligible  Employee's  account with the Appointed  Authority PROVIDED THAT if
and so long as payment by such means is rendered  temporarily  impracticable  by
reason of maternity leave,  prolonged sick leave or other similar circumstances,
the Eligible Employee may pay such  contributions by any reasonable means agreed
between  the UK  Company  or the  Subsidiary,  the  Eligible  Employee  and  the
Appointed Authority.

6.    Grant of Options

Not later than 30 days after the day the  invitations  to apply for Options were
issued  pursuant to Rule 3 (or 42 days in the event of an adjustment  under Rule
4) the UK Board  shall  grant,  or  procure  the  grant  of,  an  Option to each
applicant  who is still an Eligible  Employee over the number of Plan Shares for
which,  pursuant  to Rule  3.5  (and  subject  to Rule 4) he is  deemed  to have
applied.

statement to the effect of Rule 8.

8.    Non-Transferability of Options

An Option and an invitation  shall be personal to the Eligible  Employee to whom
it is  granted or made and shall not be capable  of  assignment.  Any  purported
charge,  pledge,  assignment,  disposal of or dealing with an Option shall cause
the Option to lapse forthwith.

9.    Limitations on Grants

9.1  The UK Board may, at the direction of the Board, before issuing invitations
     on any occasion,  determine a limit on the number of Ordinary  Shares which
     are to be available in respect of that  invitation  in order to ensure that
     Ordinary Shares remain available for subsequent invitations.

9.2  No Option shall be granted to an Eligible  Employee if the monthly  savings
     contribution under the related Savings Contract,  when added to the monthly
     savings  contributions  then being made under any other  Savings  Contract,

               of the  Company  (other  than that which is already  owned by it)

               will have Control of the Company; or

          (2)  a general  offer to  acquire  all the  Ordinary  Shares  (or such
               Ordinary  Shares  as are  not  already  owned  by  the  Acquiring
               Company); or

     (B)  obtains   Control  of  the  Company  in  pursuance  of  compromise  or

     during the  Appropriate  Period (and with the  agreement  of the  Acquiring
     Company) be released by the  Participant  for a new Option which  satisfies
     the conditions that it:-

     (A)  is over shares in the Acquiring Company or a company which has Control
          of the Acquiring  Company which  satisfy the  conditions  specified in
          paragraphs  10 to 14 inclusive  of Schedule 9 (and the terms  Ordinary
          Shares and Plan  Shares in this Plan  shall  thereafter  be  construed
          accordingly);

     (B)  is the  right  to  acquire  such  number  of  Plan  Shares  as have on
          acquisition  of the new Option an aggregate  market value equal to the

          old Option; and

          references  to the  Company  in Rule 10,  11,  12,  13, 14, 15 and the
          definitions shall, unless the context otherwise requires, be deemed to
          refer to the  Acquiring  Company  or, as the case may be, to the other
          company over whose shares the new Option is granted.

     The new  Option  shall for all other  purposes  of the Plan be  treated  as
     having been acquired at the same time as the old Option in respect of which
     it is granted.

12.3 The  provisions  of  this  Rule  12  shall  apply  with  any  consequential
     amendments  in the event  that  Control  of the  Acquiring  Company  itself

     in respect of which he wishes to exercise the Option and accompanied by the

     of repayment  under the related Savings  Contract).  Such notice shall take
     effect on the date of its receipt by the UK Company.

14.4 Subject to any necessary consents and to an Option having been exercised in
     accordance  with the  provisions  of this Rule 14, the UK Company  shall as
     soon as  practicable  and in any  event not  later  than 30 days  after the
     exercise  of an  Option  procure  an  allotment  or  the  transfer  to  the
     Participant of the number of Plan Shares specified in the notice exercising
     the Option.

14.5 For the  purposes  of Rule 14.3  above,  any  repayment  under the  Savings

     such allotment,  save that any allotment made after the earlier of the date
     of announcement of a proposed dividend or other distribution and the Record
     Date of a proposed dividend or other  distribution shall be made upon terms

Massachusetts 02110-2190 (the "Seller").

                                    Recitals

                  Operations (collectively, the "Intellectual Property");

         (vi)     all confidential and proprietary information relating
                  primarily to the Operations, including, without limitation,

the Unassigned Agreement. Notwithstanding anything to the contrary herein, the
Seller's obligations pursuant to this Section 1.1(b) shall be subject to those
limitations applicable to other Transition Services as provided in Sections
9.7(a), (b) and (c).

                  ordinary course of business;

         (ii)     the Seller's corporate, accounting and financial records

                  service marks, service mark registrations, trademarks,
                  trademark registrations and applications for trademark and
                  service mark registration, except those names listed on
                  Schedule 1.1(a)(v);

         (vi)     claims processed by the Division or submitted to the Division
                  for processing prior to the Closing Date;

         (vii)    all demands, claims, actions or causes of action which the
                  Seller may have against any person;

Payment"). The shares of Buyer Common Stock comprising the Stock Payment are
referred to in this Agreement as the "Shares".

<PAGE>

               (b) The Cash Payment must be paid by the Buyer to the Seller at
the Closing and must be paid by wire transfer of immediately available funds.
The Buyer shall deliver, or cause to be delivered, to the Seller at the Closing,
a duly executed stock certificate representing the Stock Payment.

               (c) If the price per Share, net of any underwriting commissions
and discounts, payable to the Seller (the "Per Share Sales Price") in connection
with the underwritten public offering pursuant to the Registration Statement (as
defined below) is less than $69.0219 then, not later than five (5) Business Days
after the closing pursuant to the underwriting agreement executed in connection
with such offering, the Buyer will pay to the Seller an amount equal to (x) the
difference between $69.0219 and the Per Share Sales Price multiplied by (y)
one-half of the total number of Shares issued to the Seller as the Stock
Payment, in immediately available funds by wire transfer to an account
designated by the Seller.

         1.4 Assumption of Liabilities; Etc.

               (a) At the Closing, the Buyer shall execute and deliver an
Instrument of Assumption of Liabilities (the "Instrument of Assumption")
pursuant to which it shall assume and agree to perform, pay and discharge the
liabilities, obligations and commitments of the Seller under (i) the Required
Contracts and (ii) all Consent Contracts assigned to the Buyer pursuant to
Section 1.2, which involve payments or receipts by the Seller, in the ordinary
course and consistent with the past practice of the Seller and in compliance
with law as applicable to the Buyer, to the extent that such liabilities relate
to or arise out of the use of the Acquired Assets by or for the Buyer (each such
liability being hereinafter referred to singly as an "Assumed Liability" and all
such liabilities being hereinafter referred to collectively as the "Assumed
Liabilities").

               (b) At the Closing, the Buyer shall not assume or agree to
perform, pay or discharge, and the Seller shall remain unconditionally liable
for, all claims, obligations, liabilities and commitments, fixed or contingent,
of the Seller other than the Assumed Liabilities, including all claims,
obligations, liabilities and commitments, fixed or contingent other than the
Assumed Liabilities, incurred in connection with owning, operating or otherwise
relating to the Division prior to the Closing (the "Excluded Liabilities").
Without limiting the foregoing, the Excluded Liabilities shall be deemed to
include, and the Buyer is not assuming, and shall have no obligation to
discharge or otherwise defend, any claims, obligation, liability or commitment
(i) with respect to the conduct of the Operations or any business of the
Division prior to the Closing Date, (ii) under any employee plans of the Seller,
(iii) relating to any environmental law relating to the Operations or the
Division prior to the Closing Date, (iv) based upon or arising out of any
illegal, tortious or wrongful actions of the Seller, (v) relating to Taxes now
or hereafter owed by the Seller or any affiliate of the Seller, or attributable
to the Acquired Assets or the Division, relating to any period, or any portion
of any period, ending at or prior to the Closing, (vi) relating to the Seller's
obligations under the Transaction Documents, (vii) relating to the Seller's
agreements with Electronic Data Systems, (viii) relating to or arising out of
any obligation to provide any compensation or benefits to any employee or
consultant of the Seller with respect to any work performed other than as an
employee or consultant of the Buyer or (ix) relating to or arising out of any
indebtedness for borrowed money of the Seller; provided, however, the Buyer
shall be responsible for the obligations referenced in Section 1.7 with respect
to which, and to the extent that, the Buyer has received a pro-rated benefit
therefrom pursuant to such Section 1.7.

                                       4

         1.5 Allocation of Purchase Price and Assumed Liabilities. The Purchase
Price will be allocated prior to the Closing as agreed upon by the parties
acting reasonably and in good faith. Such allocations provided for therein will
be made in accordance with the provisions of Section 1060 of the Internal
Revenue Code of 1986, as amended (the "Code"), and shall be binding upon the
Buyer and the Seller for tax purposes. The Buyer and the Seller also each agree
to prepare IRS form 8594 in accordance with the foregoing and to file such form
in accordance with Section 1060 of the Code.

         1.6 The Closing. The Closing shall take place at the offices of
Goodwin, Procter & Hoar LLP, Exchange Place, Boston, Massachusetts at 9:00 a.m.
Boston time on the last to occur of (i) February 29, 2000, (ii) the date on
which the early termination or expiration of the waiting period under the HSR
Act occurs or at such other place, time or date as may be mutually agreed upon
in writing by the parties hereto, (iii) the date next following the expiration
of thirty days after the Seller's delivery to the Office of the Massachusetts
Attorney General (the "Attorney General") of written notice given pursuant to
Section 8A of Chapter 180 of the Massachusetts General Laws (the "Massachusetts
Notice") concerning the transaction contemplated by this Agreement without any
objection to that transaction having been expressed by the Attorney General to
the Seller or, if any such objection shall have been expressed by the Attorney
General within that thirty-day period, the date next following the date upon
which all objections to the transaction expressed by the Attorney General in
response to the Massachusetts Notice shall have been withdrawn (the expiration
of the above thirty-day period without any such objection by the Attorney
General or the withdrawal of all such objections by the Attorney General being
hereinafter referred to as "Satisfaction of the Massachusetts Requirements")
(the "Closing Date").

         1.7 Proration.

                  (a) The following items will be prorated between the Buyer and
the Seller as of the Closing Date:

         (i)      prepaid lease and service contracts, including amounts
                  deposited as security in connection with any lease or other
                  contract, and other items assumed by the Buyer;

         (ii)     prepaid charges for licenses assigned by the Seller to the
                  Buyer; and

         (iii)    all other items customarily prorated and adjusted in
                  connection with the sale of property of the type contemplated
                  by this Agreement.

         All prorations required under this Section 1.7 shall be allocated so
that items relating to time periods prior to the Closing Date will be allocated
to the Seller and items relating to time periods beginning on or after the
Closing Date will be allocated to the Buyer.

                  (b) The Seller shall provide the Buyer in writing with its
good faith estimate of the amount payable to the Buyer or the Seller, as the
case may be, under Sections 1.7(a) not later than fifteen (15) days prior to the
Closing Date. The Buyer and the Seller shall agree upon an

                                       5

<PAGE>

estimate of the adjustments to be made to the Purchase Price for purposes of
determining the amount payable on the Closing Date. Within thirty (30) days
after the Closing Date, the Seller shall provide the Buyer a closing statement
(the "Seller's Closing Statement") which shall contain an explanatory letter
with back-up information, in each case setting forth the Seller's good faith
calculation of the adjustments to the Purchase Price or other amounts due
pursuant to Section 1.7 hereof. Within thirty (30) days after the Buyer's
receipt of the Seller's Closing Statement, the Buyer shall remit such amount to

Buyer and the Seller shall thereafter negotiate in good faith to resolve any
disagreements concerning the adjustments contemplated hereunder.

the Buyer shall:

         (i)      prepare and file with the SEC the Registration Statement with

<PAGE>

                  been sold, prepare any other similar offering documents that
                  may be required by law, and comply with the provisions of the
                  Securities Act with respect to the disposition of all
                  securities covered by such registration statement or offering
                  documents during such period in accordance with the intended
                  methods of disposition;

         (iii)    furnish to the Seller such number of copies of such

                  the prospectus included in such Registration Statement
                  (including each preliminary prospectus) and such other
                  documents as the Seller may reasonably request in order to
                  facilitate the disposition of the Offered Shares;

         (iv)     use its best efforts to register or qualify the Offered Shares
                  under such other securities or blue sky laws of such
                  jurisdictions of the United States as the Seller reasonably
                  requests and do any other related acts that may be reasonably
                  necessary to enable the Seller to consummate the disposition
                  in such jurisdictions (provided that the Buyer will not be
                  required to (A) qualify generally to do business in any
                  jurisdiction where it would not otherwise be required to
                  qualify but for this Section 1.8(d)(iv), or (B) consent to
                  general service of process in any such jurisdiction);

         (v)      notify the Seller, at any time when a prospectus relating
                  thereto is or would be required to be delivered under the
                  Securities Act, of the happening of any event as a result of
                  which the prospectus included in such Registration Statement
                  or any other similar offering document contains an untrue
                  statement of a material fact or omits any fact necessary to
                  make the statements therein not misleading, and the Buyer will
                  prepare a supplement or amendment to such prospectus or other
                  document so that, as thereafter delivered to the purchasers of
                  the Offered Shares, such prospectus or other document will not
                  contain any untrue statement of a material fact or omit any
                  fact necessary to make the statements therein not misleading;

         (vi)     cause all the Offered Shares to be listed on each securities
                  exchange or quotation system on which the Buyer Common Stock
                  is then listed;

         (vii)    provide a transfer agent and registrar for all the Offered
                  Shares not later than the effective date of such Registration
                  Statement;

         (viii)   enter into such customary agreements (including underwriting
                  agreements on customary terms) and take all such other actions
                  as the Seller or the underwriters reasonably request in order
                  to expedite or facilitate the disposition of the Offered
                  Shares

                                       8

<PAGE>

                  (including, without limitation, effecting a stock split or a
                  combination of shares);

         (ix)     make available for inspection by the Seller, any underwriter
                  participating in the disposition pursuant to such Registration
                  Statement, and any attorney, accountant or any other agent
                  retained by the Seller or any underwriter, all financial and
                  other records, pertinent corporate documents and properties of
                  the Buyer, and cause the Buyer's officers, directors and
                  employees to supply all information reasonably requested by
                  the Seller, any underwriter, attorney, accountant or agent in
                  connection with such Registration Statement;

         (x)      obtain a comfort letter from the Buyer's independent
                  accountants in customary form and covering such matters of the
                  type customarily covered by comfort letters and an opinion
                  from the Buyer's counsel in customary form covering such
                  matters normally covered in a public issuance of securities,
                  in each case addressed to the Seller and underwriters.

               (e) The Offered Shares will be sold pursuant to an underwritten
public offering in connection with which the Buyer shall have the right to
select the managing underwriter or underwriters; provided, however, the Seller
shall have the right to approve (i) such underwriter or underwriters and (ii)
the pricing term of such offering, including underwriting discounts and
commissions, such approval not to be reasonably withheld or delayed.

               (f) The Buyer shall pay all expenses incident to the sale of the
Offered Shares pursuant to the Registration Statement, including without
limitation, all registration and filing fees (including filing fees with respect
to the National Association of Securities Dealers, Inc.), all fees and expenses
of complying with state securities or "blue sky" laws, all printing expenses,
all listing fees, all registrars' and transfer agents' fees, the fees and
disbursements of counsel for the Buyer and of its independent certified public
accountants, including the expenses of any special audits and/or "comfort"
letters required by or incident to such performance and compliance, the fees and
disbursements of one counsel to the Seller and all underwriting discounts and
commissions.

               (g) It is a condition precedent to the obligations of the Buyer
to file the Registration Statement that the Seller (i) furnish to the Buyer such
information regarding the Seller and the Shares as the Buyer may reasonably
request and as may be required in connection with the action to be taken by the
Buyer and (ii) accept the reasonable terms of the underwriting of such offering
that have been agreed upon between the Buyer and the managing underwriter.

               (h) In connection with the registration of the Offered Shares
under the Securities Act pursuant to the terms of this Agreement, the Buyer will
indemnify and hold harmless and pay and reimburse the Seller, each underwriter
of such Shares thereunder and each other person, if any, who controls the Seller
or each such underwriter within the meaning of the Securities Act, and their
respective officers, directors, members, shareholders, employees, agents and
affiliates against any losses, claims, damages or liabilities, joint or several,
including without limitation,

                                       9

<PAGE>

costs of defense and fees and expenses of legal counsel, as and when incurred,
to which the Seller, underwriter or controlling person and their respective
officers, directors, members, shareholders, employees, agents and affiliates,
may become subject under the Securities Act or otherwise insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of any material
fact contained in the Registration Statement or any preliminary prospectus or
final prospectus contained therein, or any amendment or supplement thereof, or
arise out of or are based upon the omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein in light of the circumstance in which they were made not
misleading, or any violation of the Securities Act, the Exchange Act or any
state securities or blue sky laws, or any rule or regulation thereunder, and
will reimburse the Seller, each such underwriter and each such controlling
person and their respective officers, directors, members, shareholders,
employees, agents and affiliates, for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action; provided that the Buyer will not be liable
to the Seller, any such underwriter and any such controlling or other person
referred to above in any such case if and to the extent that any such loss,
claim, damage or liability arises out of or is based upon the Buyer's reliance
on an untrue statement or alleged untrue statement or omission or alleged
omission so made in conformity with information furnished in writing by the
Seller, such underwriter or such controlling or other person referred to above
in writing specifically stating that it is for use in such Registration
Statement or prospectus. Notwithstanding the foregoing, the indemnity provided
in this Section 1.8 shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or expense if such settlement is effected without
the consent of such indemnifying party (which consent shall not be unreasonably
withheld or delayed).

               (i) In connection with the registration of the Shares under the
Securities Act pursuant hereto, the Seller will indemnify and hold harmless the
Buyer, each person, if any, who controls the Buyer within the meaning of the
Securities Act, each officer of the Buyer who signs the Registration Statement,
each director of the Buyer, each underwriter and each person who controls any
such underwriter within the meaning of the Securities Act against all losses,
claims, damages or liabilities, joint or several, as and when incurred, to which
the Buyer or such officer, director, underwriter or controlling person may
become subject under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon reliance on any untrue statement or alleged untrue statement of
any material fact contained in the Registration Statement or any preliminary
prospectus or final prospectus contained therein, or any amendment or supplement
thereof, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, and will reimburse the Buyer and each
such officer, director, underwriter and controlling person for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided that the
Seller will be liable hereunder in any such case if and only to the extent that
any such loss, claim, damage or liability (or any action in respect thereof)
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in reliance upon and in conformity with the
Financial Statements, or information furnished in writing by the Seller, such
underwriter or such controlling or other person referred to above in writing
specifically stating that it is for use in such Registration Statement or
prospectus, and provided that the liability of the Seller hereunder

                                       10

<PAGE>

shall be limited to the net proceeds received by the Seller from the sale of
Shares covered by such Registration Statement. Notwithstanding the foregoing,
the indemnity provided in this Section 1.8 shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or expense if such
settlement is effected without the consent of such indemnifying party (which
consent shall not be unreasonably withheld or delayed).

               (j) Promptly after receipt by an indemnified party hereunder of
notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party hereunder,
notify the indemnifying party in writing thereof, but the omission so to notify
the indemnifying party shall not relieve it from any liability which it may have
to such indemnified party other than under this Section 1.8 and shall only
relieve it from any liability which it may have to such indemnified party under
this Section 1.8 if and to the extent the indemnifying party is materially
prejudiced by such omission. In case any such action shall be brought against
any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate in
and, to the extent it shall wish, to assume and undertake the defense thereof
with counsel reasonably satisfactory to such indemnified party, and, after
notice from the indemnifying party to such indemnified party of its election so
to assume and undertake the defense thereof, the indemnifying party shall not be
liable to such indemnified party under this Section 1.8 for any legal expenses
subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation and of liaison with counsel
so selected; provided that if the defendants in any such action include both the
indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded based upon written advice of its own counsel that
there may be reasonable defenses available to it which are different from or
additional to those available to the indemnifying party or if the interests of
the indemnified party reasonably may be deemed to conflict with the interests of
the indemnifying party, the indemnified party shall have the right to select a
separate counsel and to assume such legal defenses and otherwise to participate
in the defense of such action, with the expenses and fees of such separate
counsel and other expenses related to such participation to be reimbursed by the
indemnifying party as incurred.

               (k) In order to provide for just and equitable contribution to
joint liability under the Securities Act in any case in which either (i) the
Seller or any controlling person of the Seller makes a claim for indemnification
pursuant to this Section 1.8 but it is judicially determined (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration
of time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding the fact that
this Section 1.8 provides for the indemnification in such case, or (ii)
contribution under the Securities Act may be required on the part of the Seller
or any such controlling person in circumstances for which indemnification is
provided under this Section 1.8, then, in each such case, the Buyer and the
Seller will contribute to the aggregate losses, claims, damages or liabilities
to which they may be subject (after contribution from others) (i) in such
proportion as is appropriate to reflect the relative fault of the Buyer and the
Seller in connection with the statements or omissions which resulted in such
loss, claim, damage or liability, or action in respect thereof, as well as any
other relevant equitable considerations (the relative fault of the Buyer and the
Seller to be determined by reference to, among other things, whether the untrue
or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Buyer
or the Seller and the parties' relative intent, knowledge, access to information
and opportunity to

                                       11

<PAGE>

correct or prevent such statement or omission) or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in
such proportion as shall be appropriate to reflect the relative benefits
received by the Buyer and the Seller from the offering of the securities covered
by such Registration Statement; provided that, in any such case, (A) the Seller
will not be required to contribute any amount in excess of the public offering
price of all of the Shares offered by it pursuant to such Registration Statement
and (B) no person or entity guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) will be entitled to contribution
from any person or entity who was not guilty of such fraudulent
misrepresentation.

               (l) With a view to making available the benefits of certain rules
and regulations of the SEC which may permit the sale of the Shares to the public
without registration, the Buyer agrees to:

         (i)      make and keep public information available as those terms are
                  understood and defined in Rule 144 under the Securities Act,
                  at all times;

         (ii)     file with the SEC in a timely manner all reports and other
                  documents required of the Buyer under the Securities Act and
                  the Exchange Act at any time after the Closing Date; and

         (iii)    so long as the Seller owns any Shares, furnish to the Seller
                  forthwith upon request (at any time after the Closing Date) a
                  written statement by the Buyer as to its compliance with the
                  reporting requirements of Rule 144, and of the Securities Act
                  and the Exchange Act, a copy of the most recent annual or
                  quarterly report of the Buyer, and such other reports and
                  documents so filed as the Seller may reasonably request in
                  availing itself of any rule or regulation of the SEC allowing
                  the Seller to sell any such Shares without registration.

         1.9 The Seller's Contingent Rights to Put Shares to the Buyer.

               (a) Subject to Sections 1.8(e) and 18(g), if, for any reason, the
Registration Statement has not been declared effective on or before November 15,
2000 then the Seller shall have the right to demand (the "Offered Share Put")
that the Buyer purchase, at a price of $69.0219 per Share, up to 325,984 Shares
(the Shares tendered pursuant to the Offered Share Put shall be herein referred
to as the "First Put Shares"). The Seller shall notify the Buyer in writing of
its intention to exercise the Offered Share Put not later than prior to the
close of business on November 22, 2000, after which time the Offered Share Put
shall expire and be of no further force or effect. Within five Business Days
after the Seller notifies the Buyer of its exercise of the Offered Share Put,
the Seller shall deliver to the Buyer the certificates representing the First
Put Shares, free and clear of all liens, together with stock powers duly
endorsed to the Buyer on behalf of the Seller and, within two Business Days of
such delivery, the Buyer shall pay to the Seller an amount equal to (x) the
number of First Put Shares multiplied by (y) $69.0219, in immediately available
funds by wire transfer to an account designated by Seller.

                                       12

<PAGE>

               (b) Subject to Sections 1.8 (e) and 1.8(g), if, for any reason,
the Registration Statement has not been declared effective on or before December
29, 2000 then the Seller shall have the right to demand (the "Remaining Share
Put") that the Buyer purchase, for a price equal to the average closing price
per Share on the NASDAQ National Market for the ten successive trading days
ending on December 29, 2000 (the "Second Put Price") up to all of the Shares
then still held by the Seller (the Shares tendered pursuant to the Remaining
Share Put shall be herein referred to as the "Second Put Shares"). The Seller
shall notify the Buyer of its intention to exercise the Remaining Share Put not
later than prior to the close of business on January 5, 2001, after which time
the Remaining Share Put shall expire and be of no further force or effect.
Within five Business Days after the Seller notifies the Buyer of its exercise of
the Remaining Share Put the Seller shall deliver to the Buyer the certificates
representing the Second Put Shares, free and clear of all liens, together with
stock powers duly endorsed to the order of the Buyer on behalf of the Seller
and, within two Business Days of such delivery, the Buyer shall pay to the
Seller an amount (the "Second Put Amount") equal to (x) the number of Second Put
Shares multiplied by (y) the Second Put Price, in immediately available funds by
wire transfer to an account designated by the Seller. Notwithstanding the
foregoing, at the option of the Buyer, in lieu of purchasing the Second Put
Shares the Buyer may arrange for the Seller to sell the Second Put Shares to a
third party if (x) such third party agrees to purchase the Second Put Shares on
terms no less favorable, including with respect to timing, than the Remaining
Share Put and (y) in the reasonable opinion of counsel to the Seller, such sale
would not violate the Securities Act.

         1.10 Additional Registration Right.

               (a) To the extent that (x) the Offered Shares represent less than
all of the Shares, (y) all of the Offered Shares shall have been sold pursuant
to the Registration Statement, (z) the number of Shares not sold pursuant to the
Registration Statement shall equal not less than 162,992 Shares, and subject to
the provisions of this Section 1.10, the Seller shall have the right,
exercisable on or after June 4, 2001, to request that the Buyer file a second
registration statement (the "Second Registration Statement") with respect to not
less than 162,992 Shares (the Shares with respect to which such Second
Registration Statement is requested being referred to herein as the "Second
Registration Shares") for resale pursuant to an underwritten public offering and
the Buyer shall use its reasonable best efforts to file such Second Registration
Statement within 90 days after such request by the Seller.

               (b) Notwithstanding anything herein to the contrary, the Buyer
shall have the option to postpone and delay the filing or the effectiveness of
the Second Registration Statement, if the board of directors of the Buyer
reasonably determines in good faith that such registration would (i) interfere
with any material third party transaction then being pursued by the Buyer or any
of its affiliates or (ii) require the disclosure of material information
concerning the Buyer that is not yet publicly available; provided, however,
that, the Buyer shall, if required pursuant to Section 1.10(a), file the Second
Registration Statement not later than 180 days after a request by the Seller.

               (c) The provisions of Section 1.8(a), (b), (c), (d), (e), (g),

fees, that the Buyer would have incurred pursuant to Section 1.8(f) but
did not incur because the Second Registration Shares were not Offered Shares,
which shall be paid for by the Buyer.

               (e) The Seller's rights under Sections 1.9 and 1.10 shall not be
assignable.

         1.11 Reserved Rights in Names. The Buyer understands that the
Seller has been doing and will continue to do business under the name "Blue
Cross and Blue Shield" and has used, and will continue to use, and to protect
and defend its rights to use, corporate names, trade names, trademarks and
service marks employing the words "Blue Cross and Blue Shield" and the like,
both singly and in combination with other words and symbols, in connection with
its current and future businesses. It is understood and agreed that the Seller
does not, in or pursuant to this Agreement, sell, convey, assign, transfer or
grant to the Buyer, either expressly or by implication or otherwise, any right,
license or authorization to use "Blue Cross and Blue Shield" or any other
corporate name, trade name, trademark or service mark other than those that are
included in Section 1.1(a)(v) to the Seller's Disclosure Schedule.
Notwithstanding anything to the contrary herein, after the Closing the Buyer
may, in its promotional literature and correspondence, (i) disclose that, under
the terms of this Agreement, the Buyer has succeeded the Seller in the operation
of the Division and (ii) describe the Buyer's rights under the terms of the
Services Agreement and refer to the Seller in connection therewith.

judgment lien searches and Uniform Commercial Code lien searches.

Seller, in its sole discretion, may not comply with the provisions of any bulk
sales laws of any state, if any or if applicable, to the transaction
contemplated hereby.

         1.14 Further Assurances. At any time and from time to time after the
Closing, at the Buyer's request and without further consideration, the Seller
promptly shall execute and deliver such instruments of sale, transfer,
conveyance, assignment, notice and confirmation, and take such other action as
the Buyer may reasonably request to more effectively transfer, convey and assign
to the Buyer, and to confirm the Buyer's title to, all of the Acquired Assets,
to put the Buyer in actual possession and operating control thereof, to assist
the Buyer in exercising all rights with respect thereto, and to carry out the
purpose and intent of this Agreement. The Seller agrees that it will promptly
transfer or deliver to the Buyer from time to time, any cash or other property
that the Seller may receive after the Closing Date with respect to any claims,
contracts, licenses, leases, commitments, sales orders, purchase orders,
receivables of any character or any other items that may arise after the Closing
and that are included in the Acquired Assets. The Buyer agrees that it will
promptly transfer or deliver to the Seller from time to time, any cash or other

         1.15 Restrictive Legend.

               (a) Each certificate representing the Shares shall, and in each
case, subject to the provisions of and in compliance with this Agreement, be
stamped or otherwise imprinted with legends substantially in the following form:

                  "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES
                  ACT OF 1933 AND MAY NOT BE TRANSFERRED OR OTHERWISE DISPOSED
                  OF UNLESS IT HAS BEEN REGISTERED UNDER THAT ACT OR AN
                  EXEMPTION FROM REGISTRATION IS AVAILABLE."

                  "IN ADDITION, THE SHARES REPRESENTED BY THIS CERTIFICATE ARE
                  SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AS SET FORTH IN AN
                  ASSET PURCHASE AGREEMENT DATED AS OF FEBRUARY 14, 2000 AS IT
                  MAY BE AMENDED FROM TIME TO TIME, A COPY OF WHICH IS ON FILE
                  AT THE PRINCIPAL EXECUTIVE OFFICES OF THE ISSUER. NO
                  REGISTRATION OF TRANSFER OF THESE SHARES WILL BE MADE ON THE
                  BOOKS OF THE ISSUER UNLESS AND UNTIL SUCH RESTRICTIONS SHALL
                  HAVE ELAPSED OR BEEN SATISFIED OR COMPLIED WITH."

         Upon request of the Seller, and subject to the restrictions in Section
1.8(b), the Buyer will remove the foregoing legend from the certificate or issue
to the Seller a new certificate therefor free of any transfer legend, if, in
conjunction with such request, the Buyer receives either the opinion referred to
in Section 1.13(b) or the "no action" letter referred to in Section 1.13(b) to
the effect that any transfer by the Seller of the Shares represented by the
certificate will not violate the Securities Act and applicable state securities
laws.

               (b) Prior to any proposed transfer of the Shares (other than
pursuant to a Registration Statement), the Seller will give written notice to
the Buyer of its intention to effect such transfer. Each such notice must
describe the manner and circumstances of the proposed transfer in sufficient
detail, and must be accompanied (except in transaction in compliance with Rule
144) by either (i) a written opinion of Goodwin, Procter & Hoar LLP or legal
counsel who is reasonable satisfactory to the Buyer, addressed to the Buyer and
reasonably satisfactory in form and substance to the Buyer's counsel, to the
effect that the proposed transfer of the Shares may be effected without
registration under the Securities Act, or (ii) a "no action" letter from the SEC
to the effect that the proposed transfer of such securities without registration
will not result in a recommendation by the staff of the SEC that action be taken
with respect thereto, whereupon the Seller shall be entitled to transfer such
Shares in accordance with the terms of the notice delivered to the Buyer. Other
than Shares transferred pursuant to a Registration Statement, each certificate
evidencing the Shares transferred as above will bear the appropriate legend set
forth in Section 1.13(a), except that such certificate shall not bear such
legend to the extent applicable under the Securities Act if the opinion of
counsel or "no action" letter referred to above is to the further effect that
such legend is not required in order to establish compliance with any provisions
of the Securities Act.

entity or organization.

         2.1 Organization. The Seller is a non-profit hospital service
corporation and medical services corporation duly organized and validly existing
under the laws of the Commonwealth of Massachusetts with full corporate power
and authority to own, lease and operate the Acquired Assets, to execute and
deliver this Agreement and the agreements contemplated herein, and to consummate
the transactions contemplated hereby and thereby. Except as set forth in Section
2.1 to the Seller's Disclosure Schedule (the "Seller's Disclosure Schedule"),
the Seller does not own any subsidiary or interests in any corporation,
partnership, joint venture or other entity that participate in, or are
competitive with, the business of the Division.

         2.2 Authorization. The Seller has full right, authority and power to
enter into this Agreement, the Services Agreement, the Bill of Sale and the
Instrument of Assumption of Liabilities (collectively, the "Transaction
Documents") and to consummate the transactions contemplated hereby and thereby.
The execution, delivery and performance by the Seller of this Agreement and the
Transaction Documents has been duly authorized by all necessary corporate action
of the Seller, and no other corporate action on the part of the Seller is
required in connection therewith.

         This Agreement and each Transaction Document constitutes, or when
executed and delivered will constitute, the valid and binding obligation of the
Seller enforceable in accordance with its terms, except as enforcement may be
limited by bankruptcy, insolvency or similar laws affecting creditors' rights
generally and by general principles of equity. The execution, delivery and
performance by the Seller of each Transaction Document:

               (a) does not and will not violate any provision of the Seller's
organization documents;

               (b) does not and will not violate any material laws, rules or
regulations of the United States, or any state or other jurisdiction (including
but not limited to any agency, bureau, division or commission thereof) relating
to the Acquired Assets, the Operations or the Assumed Liabilities;

               (c) does not and will not, in any material respect, conflict with
or result in a breach of, constitute a default under, accelerate any obligation
under, or give rise to a right of termination, cancellation or acceleration or
to a loss of benefit under, or result in the creation of any lien, claim,
encumbrance, security interest, option, charge or restriction of any kind upon
any of the Acquired Assets under any material (with respect to the Seller and
the Acquired Assets, individually or collectively) indenture, instrument,
mortgage, lien or other agreement to which the Seller is a party and by which
any of the Acquired Assets is bound or to which any of the Operations are
subject; or

                                       16

claims, liabilities, liens, pledges, charges, collateral assignments, preemptive
or refusal rights, security interests, encumbrances and equities of any kind
affecting the Operations or the Acquired Assets (collectively, the
"Encumbrances"). The Seller is, and at the Closing will be, the true and lawful
owner of such Acquired Assets, and will have the right to sell and transfer to
the Buyer good, clear, record and marketable title to such Acquired Assets, free
and clear of all Encumbrances other than those agreed to by the parties and set
forth on Section 2.3 to the Seller's Disclosure Schedule. The delivery to the
Buyer of the instruments of transfer of ownership contemplated by this Agreement
will vest good and marketable or merchantable title to such Acquired Assets
which are tangible assets in the Buyer, free and clear of all Encumbrances other
than those agreed to by the parties and set forth in Section 2.3 to the Seller's
Disclosure Schedule.

         2.4 Litigation. Except as set forth in Section 2.4 to the Seller's
Disclosure Schedule, the Seller is not a party to, or to the best of the
Seller's knowledge threatened with, and none of the Acquired Assets or
Operations are subject to, any litigation, suit, action, investigation,
arbitration, proceeding, controversy or material claim before any court,
regulatory body, administrative agency or other governmental authority relating
to or affecting the Acquired Assets or Operations or which, if adversely
determined, would have a material adverse effect on the Acquired Assets or
Operations. The Seller is not in violation of or in default with respect to any
judgment, order, writ, injunction, decree or rule of any court, regulatory body,
administrative agency or governmental authority or any regulation of any
administrative agency or governmental authority relating to or affecting the
Acquired Assets or Operations. The parties acknowledge that the list delivered
pursuant to this Section 2.4 is for informational purposes only and the Buyer is
not assuming any claim, obligation or other liability related to the matters
described thereby. Within the 3-year period immediately preceding the date of
this Agreement, no PTG Employee has ever brought any employee-related charges or
complaints against the Seller before any governmental department or agency and,
to the knowledge of the Seller, there are no facts upon which any such charges
or complaints could be based.

substantially good operating condition and repair in all material respects,
normal wear and tear excepted.

         2.6 Assigned Contracts. Except as set forth in Section 2.6 to the
Seller's Disclosure Schedule:

         (a) each Required Contract and Consent Contract that is assigned to the
Buyer (such Required Contracts and Consent Contracts being collectively referred

agreement of the Seller and, to the best knowledge, of each of the other parties
thereto;

         (b) the Seller has not failed to fulfill any of its material
obligations required to be performed pursuant to the Assigned Contracts to the
extent that any such failure, alone or together with any other such failure, may
have a material adverse effect on the Operations or the Buyer's ability to
perform its obligations under the Services Agreement;

                                       17

<PAGE>

         (c) the Seller is not in breach of or default under any Assigned
Contract in any material respect, and no event has occurred which with the
passage of time or giving of notice or both would constitute, in any material
respect, a default, result in a loss of rights or result in the creation of any
lien, charge or encumbrance, thereunder or pursuant thereto;

         (d) to the best of the Seller's knowledge, there is no existing
material breach or default by any other party to any Assigned Contract, and no
event has occurred which with the passage of time or giving of notice or both
would constitute a material default by such other party, result in a material
loss of rights or result in the creation of any material lien, charge or
encumbrance thereunder or pursuant thereto; and

         (e) the continuation, validity and effectiveness of each Assigned
Contract will not be affected by the transfer from the Seller to the Buyer under
this Agreement.

         The representations contained in this Section 2.6 regarding the Consent
Contracts that are assigned to the Buyer are not made by the Seller at the time
of execution and delivery of this Agreement but will be made as of the Closing
Date.

         2.7 Compliance with Agreements and Laws. The Seller has all material
licenses, permits and certificates from federal, state and local authorities
necessary to own and operate the Acquired Assets, to conduct the Operations, and
to enter into and perform the Seller's obligations under the Services Agreement.
The Seller is not in violation, in any material respect, of any law, regulation
or ordinance (including, without limitation, laws, regulations or ordinances

or the Operations that it was required to file. All such Tax Returns were
correct and complete in all material respects. All Taxes owed by the Seller with

Assets that arose in connection with any failure (or alleged failure) to pay any
Tax.

Seller shall afford the officers, attorneys, accountants and other authorized
representatives of the Buyer free and full access upon reasonable notice and
during normal business hours to all management personnel, offices, properties,

to contain confidential commercial and financial information. Accordingly, the
parties agree to maintain the same as confidential, except as may be required by
law or as required to be disclosed under Sections 2.10, 3.3 and 9.3 hereof.
Notwithstanding anything to the contrary in this Agreement, the Seller

MMC shall make a reasonable effort to seek confidential treatment of any part of
such Transaction Document as the Seller reasonably requests.

any of the PTG Employees for severance pay and related benefits to the extent
set forth on Schedule 7(c) which result from the failure of the Buyer to comply
with the Buyer's obligations under Section 7(a) or from the

                                       24

incurred by the Buyer Indemnified Parties in connection with each and all of the
following:

                                       29

<PAGE>

               (a) any breach by the Seller of any representation or warranty of
the Seller in this Agreement;

               (b) any breach of any covenant, agreement or obligation of the
Seller contained in this Agreement;

               (c) fraud or any misrepresentation contained in any statement,
certificate or schedule furnished by the Seller pursuant to this Agreement and
referred to herein;

               (d) the Excluded Assets;

               (e) the Excluded Liabilities;

               (f) failure by the Seller to comply with the provisions of any

               (g) the Acquired Assets, the Division and the Operations prior to
the Closing.

Notwithstanding the provisions of Section 11.1(a), the Buyer's recourse for any
breach of the Seller's representation and warranty under Section 2.11(a) will be
limited to the Buyer's remedies with respect to any breach by the Seller of its
obligations under the provisions of Section 12.7. The provisions of Section
11.1(e), above, shall not in any way reduce the Buyer's obligations to the
Seller under Section 7, above.

         11.2 By the Buyer. The Buyer agrees to indemnify and hold harmless the
Seller, its officers, directors and employees (collectively, the "Seller
Indemnified Parties") from any and all claims, damages, liabilities, costs and
expenses (including, without limitation, settlement costs and any legal,
accounting or other expenses for investigating or defending any actions or
threatened actions) reasonably incurred by the Seller Indemnified Parties in
connection with each and all of the following:

               (a) any breach by the Buyer of any representation or warranty in
this Agreement;

               (b) any breach of any covenant, agreement or obligation of the
Buyer contained in this Agreement;

               (c) fraud or any misrepresentation contained in any statement,
certificate or schedule furnished by the Buyer pursuant to this Agreement and
referred to herein;

               (d) any claims against, or liabilities or obligations of, the

to this Agreement, as Assumed Liabilities; and

               (e) claims or liabilities with respect to the Acquired Assets and
the Operations that result solely from activities of the Buyer after the
Closing.

         It is agreed that the Buyer shall not be required to indemnify the
Seller hereunder if and to the extent the claim with respect to the Acquired
Assets or Assumed Liabilities arises from the Seller's breach of any
representation, warranty, covenant, agreement or obligation contained in this
Agreement.

                                       30

<PAGE>

         11.3 Claims for Indemnification. Whenever any claim shall arise for
indemnification hereunder the party seeking indemnification (the "Indemnified
Party"), shall promptly notify the party from whom indemnification is sought
(the "Indemnifying Party") of the claim and, when known, the facts constituting
the basis for such claim. In the event of any such claim for indemnification
hereunder resulting from or in connection with any claim or legal proceedings by
a third-party, the notice to the Indemnifying Party shall specify, if known, the
amount or an estimate of the amount of the liability arising therefrom. The
Indemnified Party shall not settle or compromise any claim by a third party for
which it is entitled to indemnification hereunder without the prior written
consent of the Indemnifying Party, which shall not be unreasonably withheld,
unless suit shall have been instituted against it and the Indemnifying Party
shall not have taken control of such suit after notification thereof as provided
in Section 11.4 of this Agreement.

         11.4 Defense by Indemnifying Party. In connection with any claim giving
rise to indemnity hereunder resulting from or arising out of any claim or legal
proceeding by a person who is not a party to this Agreement, the Indemnifying
Party at its sole cost and expense may, upon written notice to the Indemnified
Party, assume the defense of any such claim or legal proceeding if it
acknowledges to the Indemnified Party in writing its obligations to indemnify
the Indemnified Party with respect to all elements of such claim. The
Indemnified Party shall be entitled to participate in (but not control) the
defense of any such action, with its counsel and at its own expense, provided,
however, that the Indemnifying Party may not settle any such action without the
prior consent of the Indemnified Party, which consent shall not be unreasonably
withheld. If the Indemnifying Party does not assume the defense of any such
claim or litigation resulting therefrom within 30 days after the date such claim
is made, (a) the Indemnified Party may defend against such claim or litigation,
in such manner as it may deem appropriate, including, but not limited to,
settling such claim or litigation, after giving notice of the same to the
Indemnifying Party, on such terms as the Indemnified Party may deem appropriate,
and (b) the Indemnifying Party shall be entitled to participate in (but not
control) the defense of such action, with its counsel and at its own expense. If
the Indemnifying Party thereafter seeks to question the manner in which the
Indemnified Party defended such third-party claim or the amount or nature of any
such settlement (or the legal fees and costs related thereto), the Indemnifying
Party shall have the burden to prove by a preponderance of the evidence that the
Indemnified Party did not defend or settle such third-party claim in a
reasonably prudent manner.

         11.5 Payment of Indemnification Obligation.

               (a) Subject to Section 11.5(d), the maximum amount the Seller
shall be liable to pay to the Buyer pursuant to this Section 11 shall be limited
to an amount equal to $15 million.

               (b) Subject to Section 11.5(d), the Seller shall not be obligated
to pay any amount to the Buyer pursuant to this Section 11 until the aggregate
liability due exceeds $250,000, and in any event only the amount of such excess
liability shall be recoverable thereafter, subject to the terms and limitations
contained herein.

               (c) All indemnification by the Buyer or the Seller hereunder

<PAGE>

               (d) The provisions of Sections 11.5(a) and (b) and 11.6 shall not
apply to recoveries relating to the Excluded Assets or the Excluded Liabilities
or to matters arising out of the operation of the Division prior to the Closing,
all of which shall remain indefinitely the sole and exclusive responsibility of
the Seller.

         11.6 Survival of Representations; Claims for Indemnification. All
representations, warranties and covenants made by the parties herein or in any
instrument or document furnished as a Schedule hereto shall survive the Closing.
All rights of an Indemnified Party to assert a claim for indemnification under
this Section 11 on account of a breach of representation or warranty shall
expire on the date which is 18 months after the Closing Date, except for claims,
if any, asserted in writing prior to such date, which shall survive until
finally resolved and satisfied in full, provided that the Indemnified Party uses
reasonable efforts to make a claim for and pursue its rights under this Section
11. Notwithstanding the foregoing, the Excluded Assets and the Excluded
Liabilities shall remain indefinitely the sole and exclusive responsibility of
the Seller; and, after the Closing, the Acquired Assets and Assumed Liabilities
shall remain indefinitely the sole and exclusive responsibility of the Buyer. In
furtherance of the foregoing, and not in limitation thereof, (a) the Buyer
Indemnified Parties shall be entitled to assert a claim for indemnification from
the Seller at any time after the Closing with respect to the full amount of any
claims, damages, liabilities, costs and expenses in connection with the Excluded
Assets and the Excluded Liabilities and (b) the Seller Indemnified Parties shall
be entitled to assert a claim for indemnification from the Buyer at any time
after the Closing with respect to the full amount of any claims, damages,
liabilities, costs and expenses in connection with the Assumed Liabilities.

12. Additional Agreements.

         12.1 Proprietary Information.

               (a) The Seller shall hold in confidence, and use its reasonable
efforts to have all of its officers, directors and personnel hold in confidence,
all knowledge and information of a secret or confidential nature, including,
without limitation, the know-how, with respect to the Operations or Assumed
Liabilities and shall not disclose, publish or make use of the same without the
written consent of the Buyer, except to the extent that such use is necessary
for the Seller's compliance with its obligations under the Services Agreement
and to the extent that such information shall have become public knowledge other
than by breach of this Agreement by the Seller.

               (b) The Seller agrees that the remedy at law for any breach of
this Section 12.1 and of Section 12.6, below, would be inadequate and that the
Buyer shall be entitled to injunctive relief in addition to any other remedy it
may have upon breach of any provision of this Section 12.1 or of Section 12.6.

12.2     Sharing of Data.

               (a) The Seller shall have the right following the Closing Date to
have reasonable access to such books, records and accounts as are transferred to
the Buyer pursuant to the terms of this Agreement for the limited purposes of
concluding its involvement in the Acquired Assets

                                       32

<PAGE>

prior to the Closing Date and for complying with its obligations under
applicable tax or other laws and regulations.

               (b) The Seller and the Buyer agree that from and after the
Closing Date they shall reasonably cooperate fully with each other to facilitate
the transfer of the Acquired Assets from the Seller to the Buyer and the
operation thereof by the Buyer.

12.3 Cooperation in Litigation. Each party hereto will fully cooperate
with the other in the defense or prosecution of any litigation or proceeding
already instituted or which may be instituted hereafter against or by such party
relating to or arising out of the conduct of the business of the Seller prior to
or after the Closing Date (other than litigation arising out the transactions
contemplated by this Agreement). The party requesting such cooperation shall pay
the out-of-pocket expenses (including legal fees and disbursements) of the party
providing such cooperation and of its officers, directors, employees and agents
reasonably incurred in connection with providing such cooperation, but shall not
be responsible to reimburse the party providing such cooperation for such
party's time spent in such cooperation or the salaries or costs of fringe
benefits or similar expenses paid by the party providing such cooperation to its
officers, directors, employees and agents while assisting in the defense or
prosecution of any such litigation or proceeding.

         12.4 Non-Competition and Non-Solicitation.

               (a) For a period of five years after the Closing, the Seller
shall not, and will cause its affiliates not to, engage directly or indirectly
in any business that competes with the Operations as conducted on the Closing
Date; provided, however, that nothing in this Agreement shall prohibit the
Seller, from exercising any or all of its rights under the Services Agreement.

               (b) Each Party shall not, and shall not permit any of its
affiliates to, directly or indirectly, recruit, solicit, or induce (or in any
way assist another person or enterprise in recruiting, soliciting or inducing)
any employee or agent of the other party or any of its affiliates (including,
with respect to the Buyer, without limitation, any PTG Employees who are
employed by the Buyer in connection herewith) to terminate his or her employment
or other relationship with the other party or any of its affiliates during the
period commencing on the Closing Date and terminating on the fifth anniversary
of the date of the Services Agreement. The Seller may not, during the period
commencing on the Closing Date and ending on the first anniversary of the
Closing Date, hire any PTG Employee who accepts an offer of employment by the
Buyer in accordance with the Buyer's obligations under Section 7(a), above.
Nothing in this Section 12.4 shall limit the Buyer from hiring any PTG Employee
as contemplated under Section 7(a). For a period of one year from the Closing
Date, the Buyer shall not, and shall not permit any of its affiliates to,
directly or indirectly, solicit the employment of any PTG Employee who receives
any severance pay or related benefit from the Seller. For purposes of this
Section 12.4, the sole act of placing an advertisement in a newspaper
advertising for an employment position shall not constitute an act of
recruiting, soliciting or inducing.

               (c) Each party acknowledges that the covenants set forth in this
Section 12.4 are an essential element of this Agreement and that, but for the
agreement of the party to comply with these covenants, the other party would not
have entered into this Agreement. The existence of any claim or cause of action
which a party may have against the other party shall not

                                       33

<PAGE>

constitute a defense or bar to the enforcement of any of the covenants set forth
in this Section 12.4. Each party has consulted with its counsel and, after such
consultation, agrees that the covenants set forth in this Section 12.4 are
reasonable and proper.

               (d) Each party agrees that the remedy at law for any breach of
this Section 12.4 would be inadequate and that the other party shall be entitled
to injunctive relief in addition to any other remedy it may have upon breach of
this Section 12.4.

         12.5 Covenant Not to Discontinue to Use Services. Subject to the rights
and remedies, including, without limitation, the termination rights provided for
under the Services Agreement, the Seller agrees that during the term of the
Services Agreement, it shall continue to purchase from the Buyer the services
that are provided to the Seller by the Division or the Operations to the Seller
as of the Closing Date.

         12.6 Enforcement of Confidentiality Agreements. If either the Buyer, or
the Seller, in its reasonable opinion, shall believe that a party who considered
the purchase of the Operations or the Acquired Assets (a "Third-Party Bidder")
has committed a breach of a confidentiality agreement between such Third-Party
Bidder and the Seller that party shall promptly inform the other in writing, in
which event, the Buyer may request that the Seller enforce the remedies
available to it under such confidentiality agreement provided that the Buyer
furnishes the Seller with all necessary information that the Buyer may have with
respect to the alleged breach. In the event of such a request referred to in the
previous sentence, the Seller shall review the information supplied by the Buyer
and make such independent investigations as it may determine necessary or
desirable and inform the Buyer, in confidence and within a reasonable amount of
time after the request by the Buyer, whether or not, in the reasonable opinion
of the Seller, there has been a breach by a Third-Party Bidder of a
confidentiality agreement with the Seller. Thereafter, the Seller shall, in
consultation with the Buyer, use its best efforts to enforce its available
remedies against the Third-Party Bidder. The Buyer shall indemnify and hold
harmless the Seller for any and all liabilities or expenses incurred by the
Seller in connection with the actions taken by the Seller pursuant to this
Section 12.6.

         12.7 Breach of Representation in Section 2.11. If either party shall
reasonably determine, before the Second Anniversary, that the representation set
forth in Section 2.11(a) is incomplete or inaccurate, the Seller shall use its
reasonable best efforts to use or make available to the Buyer, until the Second
Anniversary, the asset, contract or service comprising such deficiency as a
Transition Service in accordance with the provisions of the Service Agreement
and Sections 9.7 (b) and (c).

13. Termination of Agreement.

         13.1 Termination by Lapse of Time. This Agreement shall terminate at
5:00 p.m., Boston time, on March 31, 1999, if the transactions contemplated
hereby have not been consummated, unless such date is extended by the written
consent of all of the parties hereto. No party shall be relieved of any
liability for breach of this Agreement due to such termination.

         13.2 Termination by Failure to Agree Upon the Services Agreement and
the Portal Agreement. If, despite their reasonable best efforts, in good faith,
to reach agreement by March

                                       34

<PAGE>

17, 2000, upon all terms of the Services Agreement and of the Portal Agreement
as referred to in Section 9.7 and 9.8, either of the parties may terminate this
Agreement.

terminated by the mutual written agreement of the parties hereto.

         13.4 Termination by Reason of Breach. This Agreement may be terminated
by the Seller, if at any time prior to the Closing there shall occur a material
breach of any of the representations, warranties or covenants of the Buyer or
the failure by the Buyer to perform any material condition or obligation
hereunder, and may be terminated by the Buyer if at any time prior to the
Closing there shall occur a material breach of any of the representations,
warranties or covenants of the Seller or the failure of the Seller to perform
any material condition or obligation hereunder.

         13.5 Termination by Change of Control. This Agreement may be terminated
by the Seller, if at any time prior to the Closing there shall occur a Change of
Control of the Buyer. As used in this Agreement "Change of Control" with respect
to the Buyer means any of the following:

               (a) any "person" or "group" (as such terms are used in Sections
13(d) and 14(d) of the Exchange Act other than MMC, is or becomes the
"beneficial owner" (as defined in Rules 13d-3 and 13d-5 under the Exchange Act,
except that a Person should be deemed to have beneficial ownership of all
securities that such Person has the right to acquire, whether such right is
exercisable immediately or only after the passage of time), directly or
indirectly, of more than 50% of the capital stock of the Buyer pursuant to which
the holders thereof have the general voting power under ordinary circumstances
to elect at least of majority of the board of directors, managers or trustees of
the Buyer;

               (b) the Buyer consolidates with, or mergers with or into, another
person or conveys, transfers, leases or otherwise disposes of all or
substantially all of its assets to any person, or any person consolidates with,
or merges with or into, the Buyer, in any such event pursuant to a transaction
in which the outstanding voting stock of the Buyer is converted into or
exchanged for cash, securities or other property;

               (c) at any time prior to the Closing Date, individuals who at the
date of this Agreement constituted the Board of Directors of the Buyer cease for
any reason to constitute a majority of the Board of Directors of the Buyer then
in office; or

               (d) the Buyer is liquidated or dissolved or adopts a plan of
liquidation or dissolution.

Notwithstanding anything to the contrary herein, consummation of the
transactions contemplated by the Agreement and Plan of Merger dated February 13,
2000, between Healtheon/Web MD Corp. and the Buyer, as it may be amended from
time to time, and the Agreement and Plan of Merger between Healtheon/Web MD
Corp. and Medical Manager Corporation, as it may be amended from time to time,
shall be deemed to not constitute a Change of Control of the Buyer for the
purposes of this Section 13.5 and will not give rise to any right of the Seller
to terminate this Agreement, the Services Agreement or the Portal Agreement.

                                       35

<PAGE>

         13.6 No Recourse. In the event of a termination pursuant to Sections

against the other party.

22. Severability.

         In case any of the provisions contained in this Agreement shall for any
reason be held to be invalid, illegal or unenforceable in any respect, any such

illegal or unenforceable provision had been limited or modified (consistent with
its general intent) to the extent necessary to make it valid, legal and
enforceable, or if it shall not be possible to so limit or modify such invalid,
illegal or unenforceable provision or part of a provision, this Agreement shall

provision had never been contained in this Agreement.

which shall be deemed to be an original, but all of which shall be one and the
