         Healtheon/WebMD  through  the merger of  OnHealth  with and into Merger
         Corp,  with OnHealth as the surviving  corporation  and thus becoming a

         including  (i)  approval  by the  stockholders  of  OnHealth  and  (ii)
         expiration   or   termination   of  the   waiting   period   under  the
         Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

                  In connection  with the Merger,  the  stockholders  and option
         holders of  OnHealth  set forth in the table  below have  entered  into
         voting  agreements,  dated as of February 15,  2000,  pursuant to which

                          AGREEMENT AND PLAN OF MERGER

         THIS  AGREEMENT  AND  PLAN OF  MERGER  (this  "AGREEMENT")  is made and
entered into as of February 15, 2000, by and among  HEALTHEON/WEBMD  CORPORATION
("HEALTHEON/WEBMD"),   a  Delaware  corporation;  TECH  ACQUISITION  Corporation
("MERGER  CORP"),  a Washington  corporation  and a wholly owned  subsidiary  of
Healtheon/WebMD;   and  ONHEALTH  NETWORK  COMPANY  ("COMPANY"),   a  Washington
corporation.


                                    PREAMBLE:

         This   Agreement   provides   for  the   acquisition   of   Company  by
Healtheon/WebMD  by means of the  merger of Merger  Corp with and into  Company,
pursuant  to which the  outstanding  shares of  Company  Common  Stock  shall be
converted into the right to receive shares of  Healtheon/WebMD  Common Stock and
Company shall become a wholly owned subsidiary of Healtheon/WebMD.  The Board of
Directors  of  Healtheon/WebMD  has  determined  that  the  Merger  is  fair  to
Healtheon/WebMD  and the holders of  Healtheon/WebMD  Common Stock and is in the
best interests of Healtheon/WebMD and such stockholders.  The Board of Directors
of  Company  (i) has  determined  that the  merger of Merger  Corp with and into
Company is fair to Company and the holders of shares of Company Common Stock and

and determined to be advisable this Agreement and the transactions  contemplated
hereby has  recommended  that the  stockholders of Company adopt this Agreement.
The Board of Directors of Merger Corp has  determined  that the merger of Merger
Corp with and into Company is in the best  interests of Merger Corp and its sole

Merger as the sole  stockholder of Merger Corp. For Federal income tax purposes,
it is  intended  that the  merger of Merger  Corp  with and into  Company  shall
qualify as a reorganization under the provisions of Section 368(a) of the United

this Agreement.

         NOW,   THEREFORE,   in  consideration  of  the  above  and  the  mutual
representations,  warranties,  covenants and  agreements  set forth herein,  the
parties agree as follows:

                                    ARTICLE 3
                           MANNER OF CONVERTING SHARES

         3.1 CONVERSION OF SHARES.  Subject to the provisions of this Article 3,
at the  Effective  Time,  by virtue of the Merger and  without any action on the
part of the Parties or the stockholders of any of the Parties, the shares of the
constituent corporations of the Merger shall be converted as follows:

                  (a)  CONVERSION  OF MERGER  CORP COMMON  STOCK.  Each share of
Merger Corp Common Stock issued and  outstanding  at the Effective Time shall be
converted  into  and  become  one (1)  fully  paid  and  nonassessable  share of
Surviving Corporation Common Stock.

                  (b) CONVERSION OF COMPANY COMMON STOCK.  Excluding shares held
by stockholders  who perfect their statutory  dissenters'  rights as provided in
Section 3.3 of this  Agreement,  each share of Company  Common  Stock issued and
outstanding  at the Effective  Time shall cease to be  outstanding  and shall be
converted  into  and  exchanged  for the  right to  receive  .189435  shares  of
Healtheon/WebMD Common Stock (as adjusted by Section 3.2, the "EXCHANGE RATIO").

                  (c) FRACTIONAL SHARES. No certificates representing fractional
shares of Healtheon/WebMD Common Stock will be issued as a result of the Merger.
Each  holder of shares of Company  Common  Stock who would  otherwise  have been
entitled to receive a fraction of a share of Healtheon/WebMD Common Stock (after
aggregating all fractional shares of Healtheon/WebMD Common Stock that otherwise
would be received by such holder)  shall,  upon  surrender of such Company stock
certificates,  receive from  Healtheon/WebMD  an amount of cash  (rounded to the
nearest  whole  cent),  without  interest,  equal  to the  product  obtained  by
multiplying  (i) such  fractional  share  interest  to which such  holder  would
otherwise be entitled by (ii) the average of the high and low sales prices for a
share of Healtheon/WebMD  Common Stock on the National Association of Securities
Dealers Automated Quotation System ("NASDAQ") Composite  Transaction Tape on the
first trading day immediately following the Effective Time.

         3.2  ANTI-DILUTION  PROVISIONS.  In the event  the  number of shares of
Healtheon/WebMD  Common Stock issued and outstanding prior to the Effective Time
changes  as  a  result  of  a  stock   split,   stock   dividend,   subdivision,
reclassification,   recapitalization,   combination   of   shares   or   similar
recapitalization  with respect to such stock (an "ANTI-DILUTION  EVENT") and the
record date  therefor (in the case of a stock  dividend) or the  effective  date
thereof  (in the case of a stock split or similar  recapitalization  for which a
record  date is not  established)  shall  be prior to the  Effective  Time,  the
Exchange Ratio shall be correspondingly  adjusted so that each holder of Company
Common  Stock  will  receive  in the  Merger  the same  proportionate  amount of
Healtheon/WebMD  Common  Stock  that such  holder  would have been  entitled  to
receive if the Effective Time had been immediately  prior to such  Anti-Dilution
Event.

         3.3 DISSENTING  SHARES.  Any holder of shares of Company  Capital Stock
who perfects its  dissenters'  rights in accordance  with and as contemplated by
Section  23B.13.210  of the WBCA  shall not be  converted  into  Healtheon/WebMD
Common  Stock but instead  shall be entitled to receive  such  consideration  as
determined  pursuant  to such  provision  of the  WBCA;  provided,  that no such
payment  shall be made to any  dissenting  stockholder  unless  and  until  such
dissenting  stockholder has complied with the applicable  provisions of the WBCA
and  surrendered to the Surviving  Corporation  the  certificate or certificates
representing  the shares for which  payment is being  made.  In the event that a
dissenting  stockholder of Company fails to perfect, or effectively withdraws or
loses,  its  right to  appraisal  and  payment  for its  shares  under the WBCA,
Healtheon/WebMD  shall issue and deliver the number of shares of Healtheon/WebMD
Common  Stock to which such  holder of shares of  Company  Capital  Stock  would
otherwise be entitled under this Article 3 (without  interest) upon surrender by
such holder of the  certificate  or  certificates  representing  such shares (or
compliance with Section 4.3) held by such holder.

         3.4      CONVERSION OF COMPANY OPTIONS.

                  (a) At the Effective  Time, each  outstanding  Company Option,
whether or not  exercisable,  shall be  converted  into and become  rights  with
respect to  Healtheon/WebMD  Common  Stock,  and  Healtheon/WebMD  shall  assume
Company's  obligations  with  respect to each  Company  Option  and the  related
Company Stock Plan, in accordance with its terms, except that from and after the
Effective  Time, (i)  Healtheon/WebMD  and its  compensation  committee shall be
substituted  for Company  and the  committee  of  Company's  Board of  Directors
(including,   if   applicable,   the  entire  Board  of  Directors  of  Company)
administering  the Company Stock Plan, if any,  under which such Company  Option
was  granted  or  otherwise  governed,  (ii)  each  Company  Option  assumed  by
Healtheon/WebMD  may be exercised  solely for shares of  Healtheon/WebMD  Common
Stock,  (iii) the number of shares of  Healtheon/WebMD  Common Stock  subject to



                                       4
<PAGE>

such Company Option shall be equal to the number of whole shares (rounded to the
nearest  whole  share) of Company  Common Stock  subject to such Company  Option
immediately  prior to the Effective Time multiplied by the Exchange Ratio,  (iv)
the per share exercise price under each such Company Option shall be adjusted by
dividing  the per share  exercise  price under each such  Company  Option by the
Exchange Ratio and rounding to the nearest whole cent, and (v) all references in
the Company  Stock Plans and the stock option  certificates  and  agreements  to
Company  (or its  predecessors)  shall be  deemed  to refer to  Healtheon/WebMD.
Notwithstanding  the  provisions of clauses (iii) and (iv) of the first sentence
of this Section 3.4(a), each Company Option which is an "incentive stock option"
shall be adjusted as required by Section 424 of the Internal  Revenue Code,  and
the regulations promulgated thereunder,  so as not to constitute a modification,
extension  or  renewal of such  Company  Option,  within the  meaning of Section
424(h) of the Internal Revenue Code.

                  (b)  As  soon  as  practicable   after  the  Effective   Time,
Healtheon/WebMD  shall  deliver to the  holders of Company  Options  appropriate
documentation  evidencing the foregoing  assumption by  Healtheon/WebMD  of such
Company Options and the related Company Stock Plan and the agreements evidencing
such Company  Options shall  continue in effect on the same terms and conditions
(subject to adjustments  required by this Section 3.4 after giving effect to the
Merger and the  provisions set forth above).  Healtheon/WebMD  shall comply with
the terms of the  Company  Stock  Plans and ensure,  to the extent  lawful,  and
subject to the  provisions of the  applicable  Company Stock Plan,  that Company
Options which  qualified as incentive  stock options prior to the Effective Time
of the Merger continue to qualify as incentive stock options after the Effective
Time of the Merger.

                  (c) Healtheon/WebMD  shall take all corporate action necessary
to reserve for issuance a sufficient number of shares of Healtheon/WebMD  Common
Stock for delivery upon the exercise of Company Options.

                  (d)  Healtheon/WebMD  agrees to file,  if available for use by
Healtheon/WebMD,  a  registration  statement  on  Form  S-8 for  the  shares  of
Healtheon/WebMD  Common Stock  issuable  with respect to the Company  Options as
soon as is reasonably  practicable  after the Effective  Time and shall maintain
the effectiveness of such registration  statement  thereafter for so long as any
such Company Options remain outstanding.

         3.5      COMPANY WARRANTS.

                  (a) At the Effective  Time,  Healtheon/WebMD  shall assume the
obligations of Company under the Company  Warrants  outstanding at the Effective
Time, whether or not the Company Warrants are then exercisable.  Thereafter, the
Company  Warrants shall  represent the right to receive upon exercise the number
of  shares of  Healtheon/WebMD  Common  Stock  equal to the  product  of (i) the
Exchange  Ratio and (ii) the number of shares of Company  Common Stock for which
such  Company  Warrant  could  have  been  exercised  immediately  prior  to the
Effective Time,  with such product  rounded to the nearest whole share.  The per
share  exercise  price  under each such  Company  Warrant  shall be  adjusted by
dividing the per share  exercise  price under each such  Company  Warrant by the
Exchange  Ratio and rounding to the nearest whole cent.  At the Effective  Time,
(i) all references in the instruments evidencing the Company Warrants to Company
shall be  deemed  to refer to  Healtheon/WebMD  and (ii)  Healtheon/WebMD  shall
assume all of Company's  obligations under such instruments with respect to such
Company Warrants as so amended.

                  (b) As soon as  practicable  after the  Effective  Time of the
Merger,  Healtheon/WebMD  shall  deliver to the holders of the Company  Warrants
documentation  evidencing the foregoing  assumption by  Healtheon/WebMD  of such
Company Warrants.

                  (c) Healtheon/WebMD  shall take all corporate action necessary

pursuant to Section  4.1(d)  (such  certificates  for shares of  Healtheon/WebMD
Common Stock,  together with the amount of any dividends or other  distributions
payable with respect thereto and any cash payable in lieu of fractional  shares,

The Exchange Fund shall not be used for any other purpose.

                  (c) EXCHANGE  PROCEDURES.  Promptly after the Effective  Time,

of any fractional  shares  pursuant to Section 3.1(d) and any dividends or other
distributions  pursuant to Section  4.1(d),  (i) 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
Healtheon/WebMD  and Company may reasonably agree) and (ii) instructions for use

<PAGE>

cancellation  to the  Exchange  Agent or to such other agent or agents as may be
appointed by  Healtheon/WebMD,  together with such letter of  transmittal,  duly
completed and validly executed in accordance with the instructions  thereto, the
holders of such  Certificates  shall be entitled to receive in exchange therefor
certificates  representing the number of whole shares of Healtheon/WebMD  Common
Stock which such holder has the right to receive under Section 3.1(b) in respect
of the shares of Company Common Stock formerly  represented by such  Certificate
and payment in lieu of  fractional  shares  which such holders have the right to
receive pursuant to Section 3.1(d),  and any dividends or distributions  payable

which such shares of Company Common Stock shall have been so converted  pursuant
to  Section  3.1(b)  and the right to  receive  an amount in cash in lieu of the
issuance of any  fractional  shares in  accordance  with Section  3.1(d) and any
dividends or distributions payable pursuant to Section 4.1(d).

                  (d)  DISTRIBUTIONS  WITH  RESPECT TO  UNEXCHANGED  SHARES.  No
dividends  or  other  distributions  declared  or made  after  the  date of this
Agreement with respect to Healtheon/WebMD  Common Stock with a record date after
the Effective Time will be paid to the holders of any unsurrendered Certificates
(other than  holders of shares to be canceled  pursuant to Sections  3.3 of this
Agreement)  with  respect  to  the  shares  of   Healtheon/WebMD   Common  Stock
represented  thereby  until the  holders  of record of such  Certificates  shall

any such Certificates,  the Exchange Agent or  Healtheon/WebMD  shall deliver to
the record holders thereof,  without interest,  certificates  representing whole
shares of  Healtheon/WebMD  Common Stock issued in exchange therefor pursuant to
Section 3.1(b) hereof along with payment in lieu of fractional  shares  pursuant
to  Section  3.1(d)  hereof  and the  amount  of any  such  dividends  or  other
distributions  with a record date after the Effective  Time payable with respect

                  (e)  TRANSFERS OF  OWNERSHIP.  If  certificates  for shares of
Healtheon/WebMD Common Stock are to be issued in a name other than that in which
the Certificates  surrendered in exchange therefor are registered,  it will be a
condition of the issuance  thereof that the  Certificates so surrendered will be
properly endorsed and otherwise in proper form for transfer and that the persons
requesting  such  exchange  will  have  paid  to  Healtheon/WebMD  or any  agent
designated by it any transfer or other taxes  required by reason of the issuance
of  certificates  for shares of  Healtheon/WebMD  Common Stock in any name other
than  that  of  the  registered  holder  of  the  Certificates  surrendered,  or
established to the satisfaction of Healtheon/WebMD or any agent designated by it
that such tax has been paid or is not payable.

                  (f)  REQUIRED   WITHHOLDING.   Each  of  the  Exchange  Agent,
Healtheon/WebMD  and the Surviving  Corporation  shall be entitled to deduct and
withhold from any  consideration  payable or otherwise  deliverable  pursuant to
this  Agreement  to any  holder or former  holder of Company  Common  Stock such
amounts as may be  required  to be  deducted  or  withheld  therefrom  under the

<PAGE>

Internal Revenue Code or under any provision of state,  local or foreign tax law
or under any other applicable legal requirement.  To the extent such amounts are
so deducted or withheld,  such amounts  shall be treated for all purposes  under
this  Agreement  as having  been paid to the person to whom such  amounts  would
otherwise have been paid.

                  (g) TERMINATION OF EXCHANGE FUND, NO LIABILITY. Any portion of
the Exchange Fund  (including  the proceeds of any  investments  thereof and any
Healtheon/WebMD  Common  Stock) that remains  unclaimed by the  stockholders  of
Company for 180 days after the Effective Time shall be paid to  Healtheon/WebMD.
Any stockholders of Company who have not theretofore  complied with this Article
4 shall thereafter look only to  Healtheon/WebMD  for payment of their shares of
Healtheon/WebMD  Common Stock and any cash, dividends and other distributions in
respect  thereof  payable  and/or  issuable  pursuant to Section  3.1(b) or this
Article 4 upon due  surrender of their  Certificates  (or  affidavits of loss in
lieu  thereof),  in each case,  without any  interest  thereon.  Notwithstanding
anything to the  contrary in this  Section  4.1,  neither  the  Exchange  Agent,
Healtheon/WebMD,  the Surviving Corporation nor any party hereto shall be liable
to a holder of shares of  Healtheon/WebMD  Common Stock or Company  Common Stock
for any amount  properly paid to a public  official  pursuant to any  applicable
abandoned property, escheat or similar Law.

         4.2 NO FURTHER  TRANSFERS OF COMPANY  COMMON  STOCK.  At the  Effective
Time,  the stock  transfer  books of Company  shall be closed and no transfer of
Company  Common  Stock by any such former  holder  shall  thereafter  be made or
recognized.  There shall be no further  recordation  of  transfers  on the stock
books of the Surviving  Corporation of shares of Company Common Stock which were
outstanding immediately prior to the Effective Time. If after the Effective Time
Certificates  are presented to the Surviving  Corporation  for any reason,  they
shall be exchanged as provided in this Article 4.

         4.3  LOST,  STOLEN  OR  DESTROYED   CERTIFICATES.   In  the  event  any
Certificates 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
Healtheon/WebMD  Common Stock,  cash for  fractional  shares,  if any, as may be
required  pursuant to Section 3.1(d) and any dividends or distributions  payable
pursuant to Section  4.1(d);  PROVIDED,  HOWEVER the Exchange  Agent 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 an indemnity
against  any  claim  that  may  be  made  against  the  Surviving   Corporation,
Healtheon/WebMD,  Company or the Exchange Agent with respect to the Certificates
alleged to have been lost, stolen or destroyed.

         4.4 RIGHTS OF FORMER  STOCKHOLDERS.  Former  stockholders  of record of
Company will not be entitled to vote or give their  consent  after the Effective
Time at any meeting or action by written consent of Healtheon/WebMD stockholders
until such  holders  have  exchanged  their  certificates  representing  Company
Capital  Stock  (other than  Company  Common  Stock to be  canceled  pursuant to
Sections 3.3 of this Agreement) for  certificates  representing  Healtheon/WebMD
Common Stock in accordance with the provisions of this Agreement.

acceleration  of  such  Company  Warrants  in the  context  of the  transactions
contemplated hereby. The Company Options that have been designated as "incentive
stock options" under the Company Stock Plans or Contracts pursuant to which such
Company  Options were granted were authorized and granted in accordance with the
rules applicable to incentive stock options under the Internal Revenue Code.

                  (c) Except for the Company  Options,  the Company Warrants and
as set forth in Section 5.3(c) of the Company  Disclosure  Letter,  there are no
outstanding warrants,  options, rights, calls or other commitments of any nature
to which Company is a party relating to Company  Common Stock,  and there are no
outstanding securities of Company convertible into or exchangeable for shares of
Company Common Stock or any other capital stock  (together with Company  Options
and Company  Warrants,  the "COMPANY EQUITY RIGHTS").  All Company Equity Rights


                                       10

were issued or granted in compliance with the 1933 Act and all applicable  state
securities  Laws,  except  where the failure to comply  would not have a Company
Material Adverse Effect.

                  (d) To  the  Knowledge  of  Company,  other  than  the  Voting
Agreements entered into pursuant to Section 8.15, there are no voting agreements
or voting trusts  between or among any Person or Persons  relating to Company or
the Company Common Stock.  Except for the Company Options,  the Company Warrants
and as set forth in Section 5.3(c) of the Company Disclosure Letter,  Company is
not  obligated to issue or  repurchase  any shares of Company  Capital  Stock or
Company  Equity  Rights  for any  purpose  and no Person  has  entered  into any
Contract  (whether  preemptive  or  contractual)  with Company for the purchase,
subscription or issuance of any unissued shares or other  securities of Company,
whether now or in the future.

                  (e)  In  Company's  reasonable  judgement,   each  Stockholder
executing a Voting  Agreement is an  affiliate of Company  within the meaning of
Rule 145 under the 1933 Act. The shares of Company  Common Stock  subject to the
Voting Agreements, together with the Company Common Stock issuable upon exercise
of the Healtheon/WebMD  Warrants (as defined in Section 8.16), are sufficient to
approve  the  Merger  and the  Agreement  for all  purposes  under  the WBCA and
Company's  Certificate of Incorporation and Bylaws,  regardless of the extent to
which Company  Options,  Company  Warrants or other Company Equity Rights may be
exercised after the date hereof.

                  (f) On a fully  exercised  (for cash) and converted to Company
Common Stock basis, the number of shares of Company Common Stock  outstanding on
the date hereof would be 31,077,335.  The weighted average exercise price of the
Company Options and Company  Warrants  outstanding on the date hereof is no less
than $6.80 per share of Company Common Stock.

         5.4 COMPANY SUBSIDIARIES.  Section 5.4 of the Company Disclosure Letter
sets forth a list of all Subsidiaries of Company.  Each Subsidiary of Company is
a corporation duly incorporated, validly existing and in good standing under the
laws of its jurisdiction of  incorporation  or organization.  Each Subsidiary of
Company has the corporate  power and authority to carry on its business as it is
now being  conducted.  Each Subsidiary of Company is duly qualified as a foreign
corporation  authorized  to do  business,  and  is in  good  standing,  in  each
jurisdiction  where the character of its properties owned or held under lease or
the nature of its activities makes such  qualification  necessary,  except where
the  failure to be so  qualified  or in good  standing  would not have a Company
Material Adverse Effect. All of the outstanding shares of capital stock or other
equity interests in each of Company's Subsidiaries have been validly issued, are
fully  paid and  nonassessable,  and,  except  as set forth in the  Company  SEC
Documents,  are owned by Company or another Subsidiary of Company free and clear
of all Liens, and none are subject to preemptive rights. Neither Company nor any
of its  Subsidiaries  has any equity or  similar  interest  in any other  Person
(other than Company's investments in its Subsidiaries).

case may be, and the  Subsequent  Company SEC Documents  (including  any and all
financial  statements  included therein) will not contain when filed, any untrue
statement  of a Material  fact with respect to Company and its  Subsidiaries  or
omit to state any  Material  fact with  respect to Company and its  Subsidiaries
required to be stated  therein or necessary to make the statements  therein,  in
light of the circumstances under which they were made not misleading.

consistent  with past practice,  except for such business and operations as have
not  resulted and would not result in a Company  Material  Adverse  Effect,  and

         5.16     BENEFIT PLANS.

                  (a) Section 5.16 of the Company  Disclosure  Letter sets forth
the name of each  Company  Plan (as defined  below) and of each bonus,  deferred
compensation  (together  with  a  list  of  participants   therein),   incentive
compensation,  profit  sharing,  salary  continuation  (together  with a list of
participants therein),  employee benefit, fringe benefit, stock purchase,  stock
option,  employment,  severance,  termination,  golden parachute,  consulting or
supplemental   retirement  plan  or  agreement   relating  to  Company  and  its
Subsidiaries or to their employees or independent contractors (collectively, the
"BENEFIT  PLANS"),  true copies of which have  heretofore been made available to
Healtheon/WebMD.  Company has also delivered to Healtheon/WebMD  true,  complete
and correct  copies of (1) each Benefit  Plan (or, in the case of any  unwritten
Benefit Plans,  descriptions thereof), (2) the two most recent annual reports on
Form 5500 (including all schedules and  attachments  thereto) filed with the IRS
with respect to each Benefit Plan (if any such report was required by applicable
Law), (3) the most recent  summary plan  description  (or similar  document) for
each  Benefit  Plan for which such a summary  plan  description  is  required by
applicable Law or was otherwise  provided to plan  participants or beneficiaries
and (4) each trust agreement and insurance or annuity  contract or other funding
or financing  arrangement  relating to any Benefit  Plan.  Each Company Plan and


                                       18
<PAGE>

Benefit Plan has been  administered in all Material  respects in accordance with
its terms and complies in all Material respects with ERISA, the Internal Revenue
Code and all other applicable Laws. All contributions to, and payments from, the
Benefit  Plans that may have been  required  to be made in  accordance  with the
terms of the Benefit Plans, any applicable  collective bargaining agreement and,
when  applicable,  Section 302 of ERISA or Section 412 of the  Internal  Revenue
Code, have been timely made. All such  contributions  to, and payments from, the
Benefit  Plans,  except those payments to be made from a trust  qualified  under
Section  401(a) of the Internal  Revenue Code,  for any period ending before the
Effective  Time  that are not yet,  but will be,  required  to be made,  will be
properly  accrued and  reflected  in the balance  sheet  included in the Company
Financial Statements.  No "reportable event" (within the meaning of Section 4043
of ERISA) has  occurred  with  respect to any Company  Plan for which the 30-day
notice  requirement  has  not  been  waived  (other  than  with  respect  to the
transactions  contemplated  by this  Agreement);  neither Company nor any of its
ERISA Affiliates has withdrawn from any Company Plan under Section 4063 of ERISA
or Company  Multiemployer  Plan (as defined below) under Section 4203 or 4205 of
ERISA or has taken, or is currently considering taking, any action to do so; and
no action has been taken,  or is currently  being  considered,  to terminate any
Company  Plan  subject  to Title IV of ERISA.  No  Company  Plan,  nor any trust
created  thereunder,  has  incurred any  "accumulated  funding  deficiency"  (as
defined in Section 302 of ERISA),  whether or not waived.  As of the most recent
valuation  date for each  Company  Plan  that is a  "defined  benefit  plan" (as
defined in Section 3(35) of ERISA (hereinafter a "DEFINED BENEFIT Plan")), there
was not any amount of  "unfunded  benefit  liabilities"  (as  defined in Section
4001(a)(18) of ERISA) under such Defined  Benefit Plan, and Company is not aware
of any facts or circumstances  that would Materially change the funded status of
any such Defined Benefit Plan. Company has furnished to Healtheon/WebMD the most
recent  actuarial report or valuation with respect to each Defined Benefit Plan.
The information  supplied to the plan actuary by Company and any ERISA Affiliate
(as defined below) for use in preparing those reports or valuations was complete
and accurate in all Material  respects and Company has no reason to believe that
the conclusions expressed in those reports or valuations are incorrect.  Neither
Company nor any ERISA  Affiliate has (a) engaged in a  transaction  described in
Section 4069 of ERISA that could subject  Company to liability at any time after
the date hereof or (b) acted in a manner that could,  or failed to act so as to,
result in Material fines, penalties,  taxes or related charges under (x) Section
502(c)(i)(1)  of  ERISA,  (y)  Section  4071 of ERISA or (z)  Chapter  43 of the
Internal Revenue Code. There are no Material  (individually or in the aggregate)
actions, suits or claims pending or, to the Knowledge of Company,  threatened in
writing  (other than routine  claims for  benefits)  with respect to any Company
Plan or  Benefit  Plan.  Neither  Company  nor any of its ERISA  Affiliates  has
incurred or could  reasonably be expected to incur any Material  liability under
or pursuant  to Title IV of ERISA that has not been  satisfied  in full.  To the
Knowledge of Company, no Material non-exempt prohibited  transactions  described
in  Section  406 of ERISA or  Section  4975 of the  Internal  Revenue  Code have
occurred.  All Company  Plans that are  intended to be qualified  under  Section
401(a) of the  Internal  Revenue  Code have  received a favorable  determination
letter as to such qualification from the IRS, and no event has occurred,  either
by reason of any action or failure to act,  which could be expected to cause the
loss of any such  qualification,  and Company is not aware of any reason why any
Company  Plan and Benefit Plan is not so  qualified  in  operation.  Company has


                                       19
<PAGE>

delivered to Healtheon/WebMD (i) a copy of the most recent  determination letter
received  with  respect  to each  Company  Plan for which such a letter has been
issued, as well as a copy of any pending application for a determination  letter
and  (ii)  a list  of all  Company  Plan  amendments  as to  which  a  favorable
determination  letter has not yet been  received.  None of  Company,  any of its
ERISA Affiliates or, to the Knowledge of Company, any trustee,  administrator or
other  fiduciary  of any Benefit Plan or any agent of any of the  foregoing  has
engaged in any transaction or acted in a manner that could, or has failed to act
so  as  to,  subject   Company,   any  such  ERISA  Affiliate  or  any  trustee,
administrator  or other  fiduciary  to any  Material  liability  for  breach  of
fiduciary duty under ERISA or any other  applicable law. Neither Company nor any
of its ERISA Affiliates knows or has been notified by any Company  Multiemployer
Plan that such Company  Multiemployer  Plan is currently  in  reorganization  or
insolvency under and within the meaning of Section 4241 or 4245 of ERISA or that
such Company  Multiemployer  Plan  intends to  terminate or has been  terminated
under  Section  4041A of ERISA.  As used  herein:  (i)  "COMPANY  PLAN"  means a
"pension  plan" (as  defined  in  Section  3(2) of ERISA,  other  than a Company
Multiemployer  Plan) or a "welfare  plan" (as defined in Section  3(l) of ERISA)
established or maintained by Company or any Person that,  together with Company,
is treated as a single  employer  under Section  414(b),  (c), (m) or (o) of the
Internal Revenue Code (each, an "ERISA AFFILIATE") or to which Company or any of
its ERISA Affiliates has contributed in the last six years or otherwise may have
any  liability;  and (ii) "COMPANY  MULTIEMPLOYER  PLAN" means a  "multiemployer
plan" (as defined in Section 4001(a)(3) of ERISA) to which Company or any of its
ERISA  Affiliates  is or has been  obligated to contribute or otherwise may have
any liability.

                  (b) Except as contemplated by this Agreement, the consummation
of the transactions  contemplated by this Agreement will not, either alone or in
combination with any other event that is reasonably likely to occur, (A) entitle
any  current or former  director,  officer or  employee of Company or any of its
ERISA  Affiliates to severance  pay,  golden  parachute  payments,  unemployment
compensation  or any  other  payment,  except  as  expressly  provided  in  this
Agreement,  or (B)  accelerate  the time of payment or vesting,  or increase the
amount of compensation due any such director, officer or employee.

                  (c) The list of welfare  plans in Section  5.16 of the Company
Disclosure  Letter  discloses  whether each welfare plan is (i)  unfunded,  (ii)
funded  through a  "welfare  benefit  fund",  as such term is defined in Section
419(e)  of the  Internal  Revenue  Code,  or other  funding  mechanism  or (iii)
insured.  Each such welfare plan may be amended or terminated  without  Material
liability to Company at any time after the Effective Time. Company and its ERISA
Affiliates comply in all Material  respects with the applicable  requirements of
Section  4980B(f) of the Internal Revenue Code with respect to each Benefit Plan
that is a group health plan,  as such term is defined in Section  5000(b)(1)  of
the Internal Revenue Code.

         5.17 BOARD  APPROVAL.  The Board of Directors of Company has, as of the
date of this  Agreement,  (a) determined  that the Merger is fair to, and in the
best interests of Company and its Stockholders,  and (b) approved and determined

recommended that the Stockholders of Company adopt this Agreement.

Healtheon/WebMD  Registration  Statement and filing any notices  required  under
state  securities  laws in  accordance  with  Section  8.1;  and (v) such  other
Consents, registrations and filings the failure of which to obtain or make would
not have a Company Material Adverse Effect.

Subsidiaries,  whether or not  reflected  in the  Company  Financial  Statements
represent  in all  Material  respects  sales  made  in the  ordinary  course  of
business,  and the reserves shown on the Company Financial  Statements have been
established in accordance with GAAP, consistently applied, and are considered by
management of Company and Company to be adequate.

         5.20 TAX TREATMENT.  Neither  Company nor, to the Knowledge of Company,
any  Affiliate of Company has taken any action or has any  Knowledge of any fact
or circumstance  that is reasonably likely to prevent the Merger from qualifying
as a reorganization within the meaning of Section 368(a) of the Internal Revenue
Code.

         5.21  AFFILIATE  TRANSACTIONS.  Except as set forth in the  Company SEC

revenues  received by Company from each such Customer during 1999.  Company does
not have any  Knowledge of any oral or written  notice from any of the Customers
stating that such Customer intends to terminate its business  relationship  with
Company or Materially reduce the volume of business it does with Company.

under the WBCA,  from a financial point of view, a written copy of which will be

                              ADDITIONAL AGREEMENTS

         8.1      STOCKHOLDER APPROVAL; REGISTRATION STATEMENT.

                  (a) Unless this Agreement is terminated in accordance with its
terms,  the Board of Directors  of Company  shall  unanimously  recommend to the
Stockholders  that  the  Stockholders  vote in  favor  of the  adoption  of this
Agreement  and the Merger and the Board of  Directors  and  officers  of Company
shall use their reasonable best efforts to obtain such  Stockholders'  approval.
Regardless of whether the Board of Directors of Company  recommends or withdraws
its  recommendation  to the Stockholders  that the Stockholders vote in favor of
the  adoption  of this  Agreement  and the  Merger,  unless  this  Agreement  is
terminated  in  accordance  with Section  10.1 hereof,  Company and its Board of
Directors  shall take all action  necessary and in accordance  with the WBCA and
its  Charter  and  Bylaws to  convene a meeting  of  Company's  Stockholders  to
consider adoption and approval of this Agreement and approval of the Merger (the
"STOCKHOLDERS  MEETING")  to be held as promptly as  practicable,  in any event,
within 30 days after the declaration of the effectiveness of the Healtheon/WebMD
Registration Statement.  Company will use its reasonable best efforts to solicit
from its  Stockholders  proxies in favor of the  adoption  and  approval of this


                                       29
<PAGE>

Agreement  and the  approval  of the  Merger,  and will  take all  other  action
necessary  or  advisable  to  secure  the vote or  consent  of its  Stockholders
required  by the  WBCA to  obtain  such  approvals  and  shall  ensure  that the
Stockholders Meeting is called, noticed,  convened, held and conducted, and that
all proxies solicited by Company in connection with the Stockholders Meeting are
solicited,  in compliance with the WBCA,  Company's Charter and Bylaws,  and all
other  applicable  legal  requirements.  The Board of  Directors  of the Company
(including any committee thereof) may not withdraw,  amend or modify, or propose
to withdraw or modify,  in a manner adverse to  Healtheon/WebMD  the approval or
recommendation by the Company Board of Directors of this Agreement or the Merger
unless,  following  the  receipt of a Superior  Proposal  (as defined in Section
8.7(c),  below),  in the  reasonable  good faith  judgment of the Company Board,
after  consultation  with outside legal  counsel,  the failure to do so would be
inconsistent  with its  fiduciary  duties to the  Company's  Stockholders  under
applicable law; PROVIDED,  HOWEVER,  that, the Board of Directors of the Company
shall submit this Agreement to the Company's stockholders for approval,  whether
or not the Board of Directors of the Company at any time  subsequent to the date
hereof  determines that this Agreement is no longer advisable or recommends that
the stockholders of the Company reject it or otherwise modifies or withdraws its
recommendation.  Unless the Board of Directors of the Company has  withdrawn its
recommendation of this Agreement in compliance  herewith,  the Company shall use
its best efforts to solicit from stockholders of the Company proxies in favor of
the  approval and  adoption of this  Agreement  and the Merger and to secure the
vote or  consent  of  stockholders  required  by the  WBCA and its  Articles  of
Incorporation and Bylaws to approve and adopt this Agreement and the Merger.

                  (b) Subject to Section 8.1(a), the Proxy  Statement/Prospectus
shall  include a statement  to the effect that the Board of Directors of Company
has recommended that the Stockholders vote in favor of the approval and adoption
of the Agreement and the Merger.  Notwithstanding  anything permitted by Section
8.1(a),  neither  Company nor its Board of Directors  shall take any action that
would cause any Voting  Agreement to be  unenforceable  in  accordance  with its
terms under applicable law.

                  (c) (i) As promptly as reasonably possible after the execution
of this  Agreement,  Company and  Healtheon/WebMD  shall prepare and cause to be
filed  with the SEC the Proxy  Statement/Prospectus  and  Healtheon/WebMD  shall
prepare  and  cause to be filed  with the SEC the  Healtheon/WebMD  Registration
Statement  in  which  the  Proxy  Statement/Prospectus  will  be  included  as a
prospectus.  Each of the Parties hereto shall provide promptly to the other such
information  concerning its business and financial statements and affairs as, in
the reasonable  judgment of the providing Party or its counsel,  may be required
or  appropriate  for  inclusion  in  the  Proxy   Statement/Prospectus  and  the
Healtheon/WebMD  Registration  Statement  or in any  amendments  or  supplements
thereto,  and to cause its counsel and  auditors to  cooperate  with the others'
counsel and auditors in  preparation of the Proxy  Statement/Prospectus  and the
Healtheon/WebMD  Registration  Statement.  Healtheon/WebMD  will  respond to any
comments  to the  SEC,  will use its  respective  commercially  reasonable  best
efforts to have the  Healtheon/WebMD  Registration  Statement declared effective
under the 1933 Act as promptly as reasonably  practicable  after such filing and


                                       30
<PAGE>

Company  will  cause the Proxy  Statement/Prospectus  to be mailed to  Company's
Stockholders  at  the  earliest   practicable  time  after  the  Healtheon/WebMD
Registration  Statement  is declared  effective  by the SEC.  Whenever any event
occurs which is required to be set forth in an amendment  or  supplement  to the
Proxy  Statement/Prospectus or the Healtheon/WebMD  Registration Statement,  the
Parties  hereto,  as the case may be,  will  promptly  inform the other  Parties
hereto of such  occurrence  and cooperate in filing with the SEC or its staff or
any other governmental officials, and/or mailing to Company's Stockholders, such
amendment or supplement.

                           (ii)     Each Party hereto hereby covenants that none
of the  information  to be  supplied  by it or on its  behalf for  inclusion  or
incorporation by reference in the Healtheon/WebMD  Registration  Statement will,
at the time such Healtheon/WebMD  Registration Statement becomes effective under
the 1933 Act,  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 not misleading.  Each Party hereto hereby covenants that
none of the  information  to be supplied by it or on its behalf for inclusion or
incorporation by reference in the Proxy  Statement/Prospectus  will, at the time
such  documents  are  filed,  when  such  documents  are  first  mailed  to  the
Stockholders  of  Company,  at the time of the  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 or necessary in order to make
the  statements  therein,  in light of the  circumstances  under which they were
made,  not  misleading.  The  Healtheon/WebMD  Registration  Statement and Proxy
Statement/Prospectus  will comply as to form in all Material  respects  with the
provisions  of the 1933 Act and the 1934 Act, as  applicable,  and the rules and
regulations promulgated by the SEC thereunder.

                  (d) Company shall cause its certified  public  accountants  to
deliver a comfort letter,  in form and substance  customary for  transactions of
this type and reasonably  satisfactory to  Healtheon/WebMD,  with respect to any
financial  information  relating  to  Company  included  in the  Healtheon/WebMD
Registration  Statement.  In the event that the  Company  has not filed its 1999
audited  financial  statements  with the SEC on or before  March 31,  2000,  the
Company  will  deliver to  Healtheon/WebMD  customary  review  letters  from its
auditors with respect to each of the first three fiscal quarters of 1999.

any such  Party to agree to any  Material  divestiture  by  itself or any of its
Affiliates  of shares of capital  stock or of any  business  or  Assets,  or the
imposition  of any Material  limitation on the ability of any of them to conduct
their businesses or to own or exercise control of such Assets or stock.

                  (b)  Healtheon/WebMD  shall use  commercially  reasonable best

other  may  reasonably  request,  provided  that  such  investigation  shall  be
reasonably  related  to the  transactions  contemplated  hereby  and  shall  not
interfere  unnecessarily  with normal  operations.  No  information or Knowledge

being a subsidiary of Company; or (D) any liquidation or dissolution of Company.
Company  and its  subsidiaries  will  immediately  cease  any  and all  existing
activities,  discussions or negotiations with any parties  conducted  heretofore
with respect to any Company  Acquisition  Proposal.  Company agrees that it will
take all necessary steps to promptly inform the individuals or entities referred
to in the first sentence of this Section 8.7(a) of the obligations undertaken in
this Section  8.7(a).  Company also agrees that if it has not already done so it
will promptly request each person that has heretofore executed a confidentiality
agreement in  connection  with its  consideration  of acquiring it or any of its
subsidiaries to return all confidential information heretofore furnished to such
person by or on behalf of it or any of its  subsidiaries.  Without  limiting the
foregoing,  it is understood that any violation of the restrictions set forth in
this Section  8.7(a) by any  officer,  director or employee of Company or any of
its  subsidiaries  or any  investment  banker,  attorney  or  other  advisor  or
representative  of  Company or any of its  subsidiaries  shall be deemed to be a
breach of this Section 8.7(a) by Company.

                  (b) In  addition  to the  obligations  of Company set forth in
paragraph   (a)  of  this  Section  8.7,   Company  shall   immediately   advise
Healtheon/WebMD  orally and in writing of any request for  information  or other
inquiry  which  Company  reasonably  believes may lead to a Company  Acquisition
Proposal, the material terms and conditions of such request, Company Acquisition
Proposal or  inquiry,  and the  identity of the person or group  making any such
request,   Company   Acquisition   Proposal  or  inquiry.   Company   will  keep
Healtheon/WebMD  informed as promptly as practicable in all material respects of
the status and details  (including  material  amendments  or  proposed  material
amendments) of any such request, Company Acquisition Proposal or inquiry.

                  (c)  Notwithstanding  subsections  (a) and  (b),  above,  that
nothing contained in this Section 8.7 shall prevent the Company or the Company's
Board of Directors from furnishing  non-public  information to, or entering into
discussions or negotiations  with, any person in connection with an unsolicited,
bona fide written Company  Acquisition  Proposal by such person,  if and only to
the extent that (1) such person has made a written proposal to the Company Board
of Directors to consummate a Company Acquisition Proposal, (2) the Company Board
of Directors  determines in good faith,  after  consultation  with the Company's
financial advisor,  that such Company Acquisition Proposal is reasonably capable
of  being  completed  on  substantially  the  terms  proposed,   and  would,  if


                                       34
<PAGE>

consummated,  result in a transaction  that would  provide  greater value to the
holders  of  Company  Common  Stock than the  transaction  contemplated  by this
Agreement (a "SUPERIOR PROPOSAL"), (3) the failure to take such action would, in
the  reasonable  good faith  judgment of the Company Board of  Directors,  after
consultation  with outside legal  counsel,  be  inconsistent  with its fiduciary
duties to the  Company's  stockholders  under  applicable  law, and (4) prior to
furnishing  such  non-public  information  to, or entering into  discussions  or
negotiations  with, such person or entity, the Company receives from such person
an executed confidentiality and standstill agreement with material terms no less
favorable  to the  Company  than  those  contained  in the  Confidentiality  and
Nonsolicitation  Agreement between Company and Healtheon/WebMD dated February 9,
2000. The Company agrees not to release any party to, or waive any provision of,
any standstill agreement to which it is a party or any confidentiality agreement
between it and another  person who has made, or who may reasonably be considered
likely to make, a Company Acquisition Proposal,  unless the failure to take such
action would, in the reasonable good faith judgment of the Company Board,  after
consultation  with outside legal  counsel,  be  inconsistent  with its fiduciary
duties to the Company's stockholders under applicable law.

                  Nothing  contained in this Section 8.7 shall prohibit  Company
from taking and disclosing to its  stockholders a position  contemplated by Rule
14e-2(a)  promulgated  under the Exchange Act or from making any  disclosure  to
Company's  stockholders if, in the good faith judgment of the Board of Directors
of Company,  after  consultation  with outside  counsel,  failure so to disclose
would be inconsistent with its obligations under applicable law.

         8.8 TAX TREATMENT. Each of the Parties undertakes and agrees to use its
reasonable efforts to take no action which would cause the Merger not to qualify
for treatment as a "reorganization"  within the meaning of Section 368(a) of the
Internal Revenue Code for federal income tax purposes.

         8.9      EMPLOYEE BENEFITS.

                  (a)  Following  the  Effective  Time,   Healtheon/WebMD  shall
provide to  officers  and  employees  of Company and its  Subsidiaries  employee
benefits  based on the  positions  they hold  with  Healtheon/WebMD  and/or  its
Subsidiaries  after the Effective Time under employee benefit plans on terms and
conditions which are substantially similar in the aggregate to those provided by
Healtheon/WebMD  and its Subsidiaries to their similarly  situated  officers and
employees  after the  Effective  Time.  With  respect to any  benefits  plans of
Healtheon/WebMD  or its  Subsidiaries  in which the  officers  and  employees of
Company   and  its   Subsidiaries   participate   after  the   Effective   Time,
Healtheon/WebMD  shall,  or shall cause the Surviving  Corporation to: (i) waive
any  limitations as to pre-existing  conditions,  exclusions and waiting periods
with respect to  participation  and  coverage  requirements  applicable  to such
officers and employees  under any welfare  benefit plan in which such  employees
may be eligible to participate after the Effective Time (provided, however, that
no such waiver  shall apply to a  pre-existing  condition of any such officer or
employee who was, as of the Effective  Time,  excluded from  participation  in a
Company  benefit plan by nature of such  pre-existing  condition),  (ii) provide
each such officer and employee with credit for any  co-payments  and deductibles


                                       35
<PAGE>

paid prior to the  Effective  Time during the year in which the  Effective  Time
occurs in satisfying any  applicable  deductible or  out-of-pocket  requirements
under any  welfare  benefit  plan in which such  employees  may be  eligible  to
participate  after the  Effective  Time,  and (iii)  other than with  respect to
vesting credit with respect to Healtheon/WebMD  options granted to such officers
and employees, recognize all service of such officers and employees with Company
and its  Subsidiaries  (and  their  respective  predecessors)  for all  purposes
(including  without limitation  purposes of eligibility to participate,  vesting
credit,  entitlement for benefits,  and benefit  accrual) in any benefit plan in
which such  employees may be eligible to participate  after the Effective  Time,
except to the extent  such  treatment  would  result in  duplicative  accrual of
benefits for the same period of service.

                  (b) Not later than the day  immediately  prior to the  Closing
Date  (the  "TERMINATION  DATE"),  Company  shall  cause  (i)  the  adoption  of
appropriate  resolutions  which  terminate each retirement plan of Company which
qualifies or is intended to qualify under Section 401(a) of the Internal Revenue
Code (each, an "COMPANY RETIREMENT PLAN"), effective as of the Termination Date,
(ii) the  cessation of all employee  salary  deferral  contributions  under each
Company  Retirement  Plan,  effective as of the Termination  Date, and (iii) the
adoption of  appropriate  resolutions,  contemporaneously  with the  adoption of
resolutions  identified  in clause (i) above,  which  reserve the right to amend
each Company Retirement Plan notwithstanding such applicable plan's termination.
Company   represents  and  warrants  that  all  contributions  to  each  Company
Retirement Plan with respect to eligible Company employees which are required to
be made by the time set forth in such  Company  Retirement  Plan or under  ERISA
(which  evidences,  in part, each Company  Retirement  Plan) with respect to the
period  ending  December  31,  1999,  have  been paid to each  applicable  trust
relating to a given Company  Retirement  Plan,  and that all such  contributions
required to be made by such time in such  Company  Retirement  Plan section with
respect to the  period  ending on the  Closing  Date will have been made to such
trust on or before the Closing Date.  Nothing in this  Agreement  shall give any
employee of Company  any  third-party  beneficiary  or other  rights  under this
Agreement.

         8.10 BLUE SKY LAWS. Healtheon/WebMD shall take such reasonable steps as
may be  necessary  to  comply  with  the  securities  and  blue  sky laws of all
jurisdictions   which  are   applicable   to  the  issuance  of  the  shares  of
Healtheon/WebMD  Common Stock in connection  with the Merger.  Company shall use
its reasonable commercial efforts to assist  Healtheon/WebMD as may be necessary
to register, or qualify for valid exemptions from, the issuance of the shares of
Healtheon/WebMD  Common  Stock in the Merger under the  securities  and blue sky
laws of all jurisdictions which are applicable in connection with such issuance.

         8.11 NON-SOLICITATION OF EMPLOYEES. Until the Effective Time or, in the
event this  Agreement is  terminated  without  completion  of the Merger,  for a
period of one (1) year from the date  hereof,  none of the Parties  will solicit
for  employment  any current  employee of the other Parties or any Subsidiary of
the other Parties unless such employee has been terminated  previously by his or
her employer nor make any offer to such employee  without prior notice to his or
her  employer;  provided  that  in no  event  will a  general  solicitation  for


                                       36
<PAGE>

employment which is not principally  directed at Company  employees  (whether by
general  advertisement in any media or otherwise) be a violation of this Section
8.11.

         8.12 PRESS RELEASES.  Prior to the Effective Time,  Healtheon/WebMD and
Company  shall consult with each other as to the form and substance of any press
release  or other  public  disclosure  related  to this  Agreement  or any other
transaction  contemplated  hereby and no Party shall issue any press  release or
make any other public disclosure without the prior approval of the other Parties
(which approval shall not be unreasonably withheld or delayed);  provided,  that
nothing in this  Section  8.12 shall be deemed to prohibit any Party from making
any  disclosure  which its counsel  deems  necessary  or  advisable  in order to
satisfy such Party's disclosure obligations imposed by Law.

         8.13     DIRECTORS AND OFFICERS INDEMNIFICATION.

                  (a)  Healtheon/WebMD  and  Company  agree  that all  rights to
indemnification  and exculpation  now existing in favor of any employee,  agent,
director or officer of Company and its Subsidiaries (the "INDEMNIFIED PARTIES"),
as  provided  in their  respective  charters  or  Bylaws  and  their  respective
Indemnification Agreements,  shall survive the Merger and shall continue in full
force and effect for a period of 3 years after the Effective Time; provided that
in the event any claim or claims are asserted or made within such 3 year period,
all rights to  indemnification in respect of any such claim shall continue until
final disposition of such claim.  Healtheon/WebMD hereby agrees, effective as of
the  Effective  Time, to guarantee  Company's  indemnification  and  exculpation
obligations  existing  in favor  of the  Indemnified  Parties,  as  provided  in
Company's and its  Subsidiaries'  respective  applicable  Charters or Bylaws and
their respective  Indemnification  Agreements,  for the period of time set forth
under this Section 8.13(a).

                  (b)  Healtheon/WebMD  agrees that from and after the Effective
Time, the Surviving Corporation shall cause the policies of director and officer
liability  insurance  maintained  by  the  Company  on  the  date  hereof  to be
maintained in effect for the period of time  directors and officers are entitled
to  indemnification  under Section  8.13(a)  above;  provided that the Surviving
Corporation  may  substitute  therefor  policies  of at least the same  coverage
containing  terms  and  conditions  which  are  no  less   advantageous  to  the
Indemnified  Parties,  provided that such  substitution  shall not result in any
gaps or lapses in  coverage  with  respect  to  matters  occurring  prior to the
Effective Time; and provided,  further, that the Surviving Corporation shall not
be  required  to pay an annual  premium  in  excess  of 150% of the last  annual
premium paid by Company prior to the date hereof (the "MAXIMUM  AMOUNT")  (which
premium is set forth in Section 8.13 of the Company Disclosure  Letter),  and if
the Surviving  Corporation  is unable to obtain the  insurance  required by this
Section  8.13  for the  Maximum  Amount,  it  shall  obtain  as much  comparable
insurance as possible for an annual premium equal to the Maximum Amount.

                  (c) In the event  Healtheon/WebMD  merges or is  acquired in a
transaction in which it is not the surviving corporation,  or if Healtheon/WebMD
sells  substantially  all of  its  assets,  Healtheon/WebMD  will  cause  proper
provision to be made in such transaction so that Healtheon/WebMD's  successor or


                                       37
<PAGE>

acquiror  will  assume the  obligations  set forth in  Sections  8.13(a) and (b)
above.  The parties  agree that  Company's  directors and officers are the third
party beneficiaries of, and entitled to enforce,  the provisions of this Section
8.13.

         8.14 COMPANY AFFILIATES;  RESTRICTIVE LEGEND; RESTRICTIONS ON TRANSFER.
Not later than 30 days prior to the Company Stockholders Meeting,  Company shall
deliver to  Healtheon/WebMD  a list of those persons who may be deemed to be, in
Company's  reasonable  judgment  at the time this  Agreement  is  submitted  for
adoption  by the  Stockholders  of  Company,  affiliates  of Company  within the
meaning  of  Rule  145  promulgated  under  the  1933  Act  (each  a  "RULE  145
AFFILIATE").  Company will provide  Healtheon/WebMD  with such  information  and
documents as Healtheon/WebMD  reasonably requests for purposes of reviewing such
list. Healtheon/WebMD will give stop transfer instructions to its transfer agent
with respect to any Healtheon/WebMD Common Stock received pursuant to the Merger
by Company  Stockholders who are Rule 145 Affiliates and there will be placed on
the  certificates   representing  such  Healtheon/WebMD  Common  Stock,  or  any
substitution therefor, a legend stating in substance:

                  "THE SHARES  REPRESENTED BY THIS  CERTIFICATE WERE ISSUED IN A
         TRANSACTION TO WHICH RULE 145  PROMULGATED  UNDER THE SECURITIES ACT OF
         1933, AS AMENDED, APPLIES AND MAY ONLY BE TRANSFERRED (A) IN CONFORMITY
         WITH RULE 145(d)  UNDER SUCH ACT, OR (B) IN  ACCORDANCE  WITH A WRITTEN
         OPINION OF  COUNSEL,  REASONABLY  ACCEPTABLE  TO THE ISSUER IN FORM AND
         SUBSTANCE  THAT SUCH  TRANSFER  IS EXEMPT FROM  REGISTRATION  UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED."

Healtheon/WebMD  will consider in good faith a request from a Rule 145 Affiliate
to remove such legend that is received on or after the one year  anniversary  of
the Closing Date.

         8.15 VOTING AGREEMENTS;  NOTICE OF RECORD DATE. Simultaneously with the
execution and delivery of this Agreement,  each of the Persons listed in Section
8.15 of the  Company  Disclosure  Letter has  executed  and  delivered  a Voting
Agreement in the form of EXHIBIT  8.15 hereto  pursuant to which such Person has
agreed,  among other things, to vote all shares of Company Capital Stock held of

Person  has been  granted  a proxy in favor of the  Merger  at the  Stockholders
Meeting (the "VOTING AGREEMENTS").  As soon as reasonably  practicable after the
date hereof,  the Company shall use its reasonable best efforts to cause each of
Ronald Stevens, Robert N. Goodman and Rebecca Farwell to execute an agreement in
favor of  Healtheon/WebMD  to exercise their Company Options upon the request of
Healtheon/WebMD, provided that Healtheon/WebMD shall (a) loan the funds required
for  such  exercise  and  (b)  indemnify   such  persons  for  any  adverse  tax
consequences  resulting from such exercise,  all on terms mutually acceptable to
the respective  parties.  Prior to 10 a.m.  eastern time on the official  record
date set by the Board of Directors of the Company for the Stockholders  entitled
to notice of and to vote at the special  meeting of the  Stockholders  taken for


                                       38
<PAGE>

the purposes of voting on the approval of the Merger (the  "Record  Date"),  the
Company shall provide  Healtheon/WebMD with notice of the total number of issued
and outstanding shares of Company Common Stock as of 10 a.m. eastern time on the
Record Date.

         8.16 LOAN AGREEMENT AND WARRANT.  Simultaneously with the execution and
delivery of this Agreement,  the Company and  Healtheon/WebMD  shall execute and
deliver a Loan Agreement in the form of EXHIBIT 8.16A (the "LOAN AGREEMENT") and
in connection therewith the Company shall issue and deliver to Healtheon/WebMD a

meaning of 368(a) of the Internal  Revenue Code,  which opinion shall be in form
and  substance   reasonably   satisfactory  to   Healtheon/WebMD   and  Company,
respectively;  provided,  however, that if counsel to either  Healtheon/WebMD or
Company does not render such opinion, this condition shall nonetheless be deemed
to be satisfied with respect to such Party if counsel to the other Party renders

there is a  reasonable  probability  that there will be a material  delay in the
effectiveness of the registration  statement filed, or contemplated to be filed,

         of the  Shares  or the  granting  of any  proxy,  except  for any  such
         encumbrances or proxies arising hereunder.

         4.       GRANT OF IRREVOCABLE PROXY; APPOINTMENT OF PROXY.

                  (a)  The  Stockholder   hereby   irrevocably  grants  to,  and

         Healtheon/WebMD,  W. Michael Long, Chairman and Chief Operating Officer
         of Healtheon/WebMD, Robert Draughon, Vice President of Healtheon/WebMD,
         and Jack  Dennison,  Vice President of  Healtheon/WebMD,  or any one of
         them, in their  respective  capacities as officers of  Healtheon/WebMD,
         and any  individual who shall  hereafter  succeed to any such office of
         Healtheon/WebMD, and each of them individually, the Stockholder's proxy
         and attorney-in-fact (with full power of substitution),  for and in the
         name,  place and stead of the  Stockholder,  to vote the  Stockholder's
         Shares at any meeting of  stockholders  of Company  (including  without
         limitation the Company  Stockholders  Meeting),  or at any  adjournment
         thereof or in any other  circumstances  upon  which a vote,  agreement,
         consent  or other  approval  is  sought,  on the  matters  set forth in
         Section 2 hereof  and to request  in  writing  in  accordance  with the
         Bylaws of Company,  or other appropriate  manner, that the President or
         Secretary  of Company  call a special  meeting of the  stockholders  of
         Company  to vote on the  matters  set forth in  Section 2 hereof.  Such
         attorney-in-fact  may evidence the taking of any action,  giving of any
         consent or the voting of the Shares by the execution of any document or
         instrument for such purpose in the name of the Stockholder.

                  (b) The  Stockholder  represents  that  any  proxies  given in
         respect of the Stockholder's  Shares prior to the granting of the proxy
         set  forth in this  Agreement  are not  irrevocable,  and that any such
         proxies are hereby revoked.

                  (c) The Stockholder  hereby affirms that the irrevocable proxy
         set forth in this Section 4 is given in  connection  with the execution
         of the Merger  Agreement,  and that such irrevocable  proxy is given to
         secure  the  performance  of the duties of the  Stockholder  under this
         Agreement.  The Stockholder hereby further affirms that the irrevocable
         proxy is coupled  with an interest  and may under no  circumstances  be
         revoked.  The  Stockholder  hereby  ratifies and confirms all that such
         irrevocable proxy may lawfully do or cause to be done by virtue hereof.
         SUCH  IRREVOCABLE  PROXY IS EXECUTED AND INTENDED TO BE  IRREVOCABLE IN

         5. CERTAIN EVENTS.  The Stockholder  agrees that this Agreement and the
obligations  hereunder  shall  attach to the  Stockholder's  Shares and shall be
binding upon any person or entity to which legal or beneficial ownership of such
Shares shall pass,  whether by operation of law or otherwise,  including without
limitation the  Stockholder's  successors or assigns.  In the event of any stock
split, stock dividend, merger, reorganization,  recapitalization or other change
in the capital structure of Company,  or the acquisition of additional shares of
Company Capital Stock or other voting  securities of Company by any Stockholder,
the number of Shares  subject to the terms of this  Agreement  shall be adjusted
appropriately  and this Agreement and the obligations  hereunder shall attach to
any  additional  shares of Company  Capital Stock or other voting  securities of
Company issued to or acquired by the Stockholder.

         6.  FURTHER   ASSURANCES.   The  Stockholder  shall,  upon  request  of
Healtheon/WebMD and Merger Corp execute and deliver any additional documents and
take such further  actions as may  reasonably be deemed by  Healtheon/WebMD  and
Merger Corp to be necessary or desirable to carry out the provisions  hereof and
to vest the power to vote such Stockholder's Shares as contemplated by Section 4
in  Healtheon/WebMD  and the other irrevocable  proxies described therein at the
expense of Healtheon/WebMD.

         7. TERMINATION.  This Agreement,  and all rights and obligations of the
parties hereunder;  including without limitation, the proxy set forth in Section
4,  shall  terminate  upon the first to occur of (i) the  Effective  Time of the
Merger,  (ii)  the date  upon  which  the  Merger  Agreement  is  terminated  in
accordance with its terms or (iii) October 31, 2000.

         8.       MISCELLANEOUS.

                  (a)  This   Agreement   may  be   executed   in  two  or  more
         counterparts,  all of  which  shall  be  considered  one and  the  same
         agreement.

                  (b) This Agreement  (including  the documents and  instruments
         referred to herein)  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.

                  (c) This  Agreement  shall be governed  by, and  construed  in
         accordance with, the laws of the State of Washington, regardless of the
         laws  that  might  otherwise  govern  under  applicable  principles  of
         conflicts of laws thereof.

                  (d) Neither this Agreement nor any of the rights, interests or
         obligations  under this  Agreement  shall be  assigned,  in whole or in
         part, by operation of law or otherwise,  by any of the parties  without
         the prior  written  consent of the other  parties.  Any  assignment  in
         violation of the foregoing shall be void.

                  (e) The Stockholder agrees that irreparable damage would occur
         and that  Healtheon/WebMD,  Merger  Corp or Company  would not have any
         adequate  remedy at law 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 Healtheon/WebMD,
         Merger  Corp  or  Company   shall  be  entitled  to  an  injunction  or
         injunctions  to prevent  breaches by the  Stockholder of this Agreement
         and to enforce specifically the terms and provisions of this Agreement,
         this being in addition to any other  remedy to which they are  entitled
         at law or in equity.

                  (f) If any term, provision, covenant or restriction herein, or
         the application thereof to any circumstance,  shall, to any extent, (i)
         be held by a court of  competent  jurisdiction  to be invalid,  void or
         unenforceable  or (ii) would  preclude the Merger from  qualifying as a
         reorganization  within the  meaning of Section  368(a) of the  Internal
         Revenue Code of 1986,  as amended,  such term,  provision,  covenant or
         restriction shall be modified or voided, as may be necessary to achieve
         the intent of the parties to the extent possible,  and the remainder of
         the  terms,  provisions,  covenants  and  restrictions  herein  and the
         application  thereof to any other  circumstances,  shall remain in full
         force  and  effect,  shall  not in any  way be  affected,  impaired  or
         invalidated,  and shall be enforced to the fullest extent  permitted by
         law.

                  (g) No  amendment,  modification  or waiver in respect of this
         Agreement  shall be  effective  against any party unless it shall be in
         writing and signed by such party.
