(1) Based upon the total number of options that we granted to our employees
    during 2000.

(2) The estimated grant date present value reflected in the above table is
    determined using the Black-Scholes model. The material assumptions and
    adjustments incorporated in the Black-Scholes model in estimating the value
    of the options reflected in the above table include the following: (a) the
    respective option exercise prices, (b) the exercise of options within three
    and one-half years of the date that they become exercisable, (c) a risk-free
    interest rate of 5.29% per annum and (d) volatility of 1.0. The ultimate
    values of the options will depend on the future market price of our common
    stock which cannot be forecast with reasonable accuracy. The actual value,
    if any, an optionee will realize upon exercise of an option will depend on
    the excess of the market value of our common stock over the exercise price
    on the date the option is exercised. We cannot assure you that the value
    realized by an optionee will be at or near the value estimated by the
    Black-Scholes model or any other model applied to value the options.

(3) Does not include options to purchase shares of Medical Manager common stock
    that we assumed in our merger with Medical Manager and that were converted
    in that merger into options to purchase 3,000,000 shares of our common stock
    at an exercise price of $12.75 per share, 25,000 shares of our common stock
    at an exercise price of $10.00 per share, 25,000 shares of our common stock
    at an exercise price of $14.80 per share, 25,000 shares of our common stock
    at an exercise price of $15.50 per share, 25,000 shares of our common stock
    at an exercise price of $22.90 per share and 585,000 shares of our common
    stock at an exercise price of $13.8462 per share.

(4) Pursuant to a letter agreement that we entered into with Mr. Arnold on
    October 11, 2000 in connection with his resignation as our Co-Chief
    Executive Officer, these options became fully vested and exercisable on that
    date. For more information, see "Compensation arrangements with executive
    officers -- Arrangements with Mr. Arnold" below.

(5) Does not include options to purchase shares of Medical Manager or CareInsite
    common stock that we assumed in our mergers with Medical Manager and
    CareInsite on September 12, 2000 and that were converted in those mergers
    into options to purchase 1,125,000 shares of our common stock at an exercise
    price of $25.80 per share, 1,125,000 shares of our common stock at an
    exercise price of $11.55 per share, 750,000 shares of our common stock at an

shares of our common stock at an exercise price of $52.4519 per share and
585,000 shares of our common stock at an exercise price of $16.8269 per share.

(6) 25% of these options vest and become exercisable on the first anniversary of
    the date of grant and the remainder vest and become exercisable at the rate
    of 1/48(th) per month thereafter for the next three years. These options
    were granted to Ms. Fili-Krushel on May 12, 2000 and to Mr. Draughon on
    April 6, 2000, with respect to options to purchase 100,000 shares, and on
    September 12, 2000, with respect to options to purchase 250,000 shares.

(7) Pursuant to letter agreements that we entered into with Mr. Dennison on
    September 12, 2000 and October 11, 2000, these options became fully vested
    and exercisable when Mr. Dennison resigned on January 26, 2001. For more

DIRECTOR COMPENSATION

     Our directors do not receive any cash fees for their service on our board
or any board committee, but they are entitled to reimbursement for all
reasonable out-of-pocket expenses incurred in connection with their attendance
at board and board committee meetings. All board members are eligible to receive
stock options under our 2000 Long-Term Incentive Plan, and outside directors
receive stock options pursuant to automatic grants of stock options under our
2000 Long-Term Incentive Plan annually on January 1. Prior to the adoption of
our 2000 Long-Term Incentive Plan, board members were eligible to receive stock
options under our 1996 Stock Plan, and outside directors received stock options
pursuant to automatic grants under that plan.

     In January 2000, we granted to Mr. Doerr and to each of the four other
outside directors at that time options to purchase 20,000 shares of our common
stock under the 1996 Stock Plan with an exercise price equal to $37.50 per
share. In November 2000, we granted to Dr. Adler and to each of Messrs. Brooke,

COMPENSATION ARRANGEMENTS WITH EXECUTIVE OFFICERS

  Arrangements with Martin J. Wygod

     Letter agreement.  On June 18, 2000, we entered into a letter agreement
with Martin J. Wygod, who at the time was serving as Medical Manager's and
CareInsite's Chairman, which became effective upon the completion of our mergers
with Medical Manager and CareInsite in September 2000. The letter agreement
provides that if Mr. Wygod's employment with us terminates for any reason, or he
ceases to serve as our Co-Chief Executive Officer or Chief Executive Officer for
any reason, each option held by Mr. Wygod at the time of the mergers, other than
the options granted pursuant to the option agreement described below, will
continue to vest in accordance with the applicable schedule and will otherwise
be treated as if he remained employed through the earlier of the first
anniversary of the last scheduled vesting date for those options or the material
breach by him of the restrictive covenants contained in the letter agreement,
which are described below.

     The letter agreement provides that, except as otherwise permitted, until
the earlier of the second anniversary of the date Mr. Wygod is neither a member
of our board of directors nor our Co-Chief Executive Officer or Chief Executive
Officer or September 2003, Mr. Wygod will not engage in business activities that
are either substantially similar to, or competitive with, the businesses engaged
in by Medical Manager and CareInsite at the time of the mergers. In addition,
until the end of Mr. Wygod's noncompete period, Mr. Wygod is subject to
nonsolicitation and confidentiality provisions.

     Option agreement.  On August 21, 2000, Medical Manager entered into an
amended and restated option agreement with Mr. Wygod, which we assumed upon
completion of the Medical Manager merger. Mr. Wygod was granted options to
purchase shares of Medical Manager common stock, which were converted in the
Medical Manager merger into options to purchase 3,000,000 shares of our common
stock at an exercise price of $12.75 per share.

     The options vest in equal monthly installments commencing on September 1,
2000, except that if Mr. Wygod's employment is terminated due to his death or
disability, by us without "cause" or by Mr. Wygod for "good reason," as those
terms are defined in the option agreement, all unvested options will become
fully vested and exercisable on the date of termination. In addition, if Mr.
Wygod's employment is terminated by us with cause or by Mr. Wygod without good
reason, all unvested options will terminate and be cancelled on the date of
termination. If a "change in control," as defined in the option agreement,
occurs, all unvested options will become fully vested and exercisable on the
date of the change in control. The options are not exercisable following the
tenth anniversary of the date of grant.

     The option agreement contains a tax gross-up provision relating to any
excise taxes that Mr. Wygod incurs by reason of his receipt of any payment that
constitutes an excess parachute payment as defined in Section 280G of the tax
code.

  Arrangements with Jeffrey T. Arnold

     In connection with Jeffrey T. Arnold's resignation as our Co-Chief
Executive Officer in October 2000, we entered into a letter agreement with Mr.
Arnold dated October 11, 2000. Pursuant to the October letter agreement, we paid
Mr. Arnold $4,000,000 and agreed to continue his participation in our benefit
plans until the earlier of the 18-month anniversary of the date of termination
and the date on which Mr. Arnold becomes covered by another comparable plan. Mr.
Arnold's resignation was treated as a

                                        9
<PAGE>   11

termination without cause and, as a result, all of his outstanding options
became fully vested at the time of his resignation and will remain exercisable
for ten years from the applicable date of grant.

     Mr. Arnold is subject to noncompetition, nonsolicitation and
confidentiality provisions. Mr. Arnold is entitled to receive a tax gross-up
payment to the extent of any excise taxes he incurs by reason of his receipt of
any payment that constitutes an excess parachute payment as defined in Section
280G of the tax code.

  Arrangements with Marvin P. Rich

     On June 18, 2000, Medical Manager and CareInsite entered into an amended
and restated employment agreement with Marvin P. Rich, which was subsequently
modified by a letter agreement dated September 11, 2000. We assumed the
obligations of Medical Manager under the employment agreement upon completion of
the Medical Manager merger. The term of the agreement ends on January 4, 2005,
subject to automatic monthly renewal. The employment agreement provides for Mr.
Rich's appointment as President of Medical Manager and Chief Executive Officer
of CareInsite. Upon completion of the mergers, Mr. Rich became our President.
The employment agreement also provides that during the term of his employment,
we will use our best efforts to include Mr. Rich in management's nominees for
election, and recommend his election, as a member of our board of directors. The
employment agreement provides for an annual aggregate base salary of $500,000,
subject to increase at the discretion of the board or the compensation committee
of the board, and an annual aggregate performance bonus of up to $500,000. Each
of Medical Manager and CareInsite made a full recourse loan to Mr. Rich in the
principal amount of $300,000, which loans, together with accrued interest of
approximately $34,000 in the aggregate, were forgiven in full in September 2000
on the completion of the mergers.

     If Mr. Rich resigns for "good reason" or his employment is terminated by us
without "cause," as those terms are defined in his employment agreement, he will
be entitled to continuation of his base salary for three years, continued
participation in our benefit plans for three years or, if earlier, until he is
offered comparable coverage with a subsequent employer, and the aggregate bonus
that would have been payable for three years, based on the highest bonus paid
during the prior three years or, if shorter, during the term of his employment.
In addition, all outstanding options granted to Mr. Rich prior to the completion
of the mergers will become fully vested and immediately exercisable upon the
date of such termination and remain exercisable through the tenth anniversary of
the applicable date of grant.

     Notwithstanding the foregoing, if an event occurs prior to September 12,
2001 that would constitute good reason, Mr. Rich has agreed to remain employed
until September 12, 2001, and he would be entitled to receive the severance
benefits described above upon his resignation after that date, except that his
outstanding options would become fully vested and immediately exercisable at the
time such good reason event occurs. In the event that Mr. Rich is terminated for
cause or resigns prior to September 12, 2001, he would forfeit his outstanding
options and would be required to disgorge any gains realized upon prior exercise
of such options.

     If Mr. Rich's employment is terminated due to his death or disability, he
will be entitled to the same benefits described above, but for four years, and
Mr. Rich's outstanding options granted to him prior to the completion of the
mergers will remain outstanding and continue to vest as if he remained employed
by us until the fourth anniversary of the date of termination. If Mr. Rich's
employment agreement is terminated by us for cause, he will receive only base
salary that was earned but unpaid as of the date of termination.

     The employment agreement contains confidentiality obligations, some of
which survive indefinitely, and nonsolicitation and noncompetition obligations
that end on the second anniversary of the date employment has ceased.

     The employment agreement contains a tax gross-up provision relating to any
excise taxes that Mr. Rich incurs by reason of his receipt of any payment that
constitutes an excess parachute payment as defined in Section 280G of the tax
code.

  Arrangements with Patricia Fili-Krushel

     Patricia Fili-Krushel, our Chief Executive Officer, Consumer Sales and

increase in the discretion of the compensation committee of our board with the
approval of our full board. In addition, Ms. Fili-Krushel will be entitled to an
annual bonus based on performance criteria established from year to year by the
compensation committee, but which will be at least $500,000 for each year during
the term. We will also provide Ms. Fili-Krushel with term life insurance of not
less than $5,000,000.

  Arrangements with K. Robert Draughon

     In connection with the WebMD, Inc. merger, we became party to an employment
agreement effective February 1, 1998 with K. Robert Draughon which, as modified
by a letter agreement dated September 12, 2000, is described below. The
employment agreement provides for Mr. Draughon's appointment as our Executive
Vice President, Business Development. Pursuant to the employment agreement, Mr.
Draughon is to receive an annual base salary of $450,000 and is entitled to
participate in any bonus program established by us for our senior executive
officers.

     Upon termination of Mr. Draughon's employment due to his death or
disability, by us without "cause" or by Mr. Draughon for "good reason," as those
terms are defined in Mr. Draughon's employment agreement, he will be entitled to
continuation of his base salary for twelve months and continuation of benefit
plans for twelve months. In addition, all options granted to Mr. Draughon prior
to December 31, 2000 which have not vested prior to the date of termination will
be vested as of the date of termination and all such options will continue to be
exercisable until the tenth anniversary of the applicable date of grant.

     If Mr. Draughon's employment is terminated by us for cause or by him
without good reason, he is not entitled to any further compensation or benefits.
In addition, any options granted to him prior to December 31, 2000 which have
not vested prior to the date of termination will be forfeited, and any such
options which have vested at that time will continue to be exercisable until the
tenth anniversary of the applicable date of grant.

     The employment agreement contains confidentiality obligations, some of
which survive indefinitely and some of which end on the first anniversary of the
date employment has ceased, and nonsolicitation and noncompetition obligations
that end on the second anniversary of the date employment has ceased.

     The employment agreement contains a tax gross-up provision relating to any
excise taxes that Mr. Draughon incurs by reason of his receipt of any payment
that constitutes an excess parachute payment as defined in Section 280G of the
tax code.

  Arrangements with Jack D. Dennison

     On September 12, 2000, we entered into a letter agreement with Jack D.
Dennison which was modified by a letter agreement dated October 11, 2000.

     Mr. Dennison resigned effective January 26, 2001 and, in accordance with
the terms of the letter agreement, the resignation was mutually agreed to be for
good reason. As a result, Mr. Dennison is entitled to continuation of his base
salary of $450,000 for twelve months and continuation of benefit plans for
twelve months. In addition, all options which were not vested prior to the date
of termination became vested as of that date and all options will continue to be
exercisable until the tenth anniversary of the applicable date of grant.

     The letter agreement contains nonsolicitation and noncompetition
obligations that end on January 26, 2003.

     The letter agreement contains a tax gross-up provision relating to any
excise taxes that Mr. Dennison incurs by reason of his receipt of any payment
that constitutes an excess parachute payment as defined in Section 280G of the
tax code.

ITEM 12.  SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

     The following table sets forth information with respect to the beneficial
ownership of our common stock as of April 9, 2001 by each person known by us to
own beneficially more than 5% of our common stock, each of our directors and
named executive officers and by all of our directors and executive officers as a
group.

     The number and percentage of our shares of common stock owned is based on
357,047,843 shares outstanding as of April 9, 2001. Beneficial ownership is
determined under the rules and regulations of the SEC. Shares of common stock
subject to options or warrants that are currently exercisable or exercisable
within 60 days of April 9, 2001 are deemed to be outstanding and beneficially
owned by the person holding the options or warrants for the purpose of computing
the number of shares beneficially owned and the percentage ownership of that
person. The shares subject to options or warrants held by a person are not
deemed to be outstanding for the purpose of computing the percentage ownership
of any other person. Except as indicated in the footnotes to this table, and
subject to applicable community property laws, these persons have sole voting
and investment power with respect to all shares of our common stock shown as
beneficially owned by them. Unless otherwise indicated, the address of each of
the beneficial owners identified is c/o WebMD Corporation, 669 River Drive,
Center 2, Elmwood Park, New Jersey 07407-1361.

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     Since January 1, 2000, there has not been, nor is there currently proposed,
any transaction or series of similar transactions to which we or any of our
subsidiaries was or is to be a party in which the amount involved exceeds
$60,000 and in which any director, executive officer, holder of more than 5% of
our common stock or any member of the immediate family of any of the foregoing
persons had or will have a direct or indirect material interest other than the
transactions described below.

  Microsoft

     We entered into a five-year strategic alliance with Microsoft in May 1999.
In March 2001, we executed a non-binding letter of intent with Microsoft with
respect to revisions to the relationship. In April 2001, we entered into
definitive agreements with Microsoft to implement the revised relationship. The
original and revised strategic relationships are described below.

     Original strategic relationship.  Under the terms of the original strategic
relationship, WebMD has been developing, hosting and maintaining on our servers
a health channel for MSN and was required to pay Microsoft an aggregate of
$162,000,000 in carriage fees for the distribution of that content. In addition,
Microsoft and WebMD each committed co-marketing funds of $50,000,000 over the
first two years of the term. As of December 31, 2000 and 1999, WebMD had
recognized $30,562,000 and $3,950,000, respectively, as sales and marketing
expense related to the carriage fees.

     Microsoft was required to remit to WebMD 100% of the net revenue over the
term of the agreement from banner and other advertising and e-commerce
transactions generated on the health channel or advertising that Microsoft
placed on WebMD.com each year during the term until we received an amount equal
to that year's carriage fees, including guaranteed minimum amounts of
$22,500,000 in each of the first two years of the term, and was required to
share revenue equally with us after that. We were required to pay Microsoft a
25% commission on the portion of the revenue received up to the annual
guaranteed minimum amounts for all advertisements placed by Microsoft. We
recognized this advertising revenue when Microsoft notified us that
advertisements had been placed on the health channel and billed by Microsoft,
not based on the guaranteed minimum amounts. During 2000 and 1999, we recognized
$5,996,000 and $1,590,000, respectively, net of commissions, related to health
channel advertising.

     Microsoft agreed to sponsor up to 5.0 million subscriber months, for $29.95
per month, of subscriptions to our physician Web site over the term of the
agreement. We were required to pay a $5 per month commission on all
subscriptions placed by Microsoft. During 2000 and 1999, WebMD recorded
$16,114,000 and $1,845,000, respectively, as revenue, net of commissions,
related to subscriptions sponsored by Microsoft.

     WebMD was required to share with Microsoft 50% of net revenue from banner
and other advertising on our physician Web site generated by sponsored
subscriptions until Microsoft received the amount it had

                                        14
<PAGE>   16

incurred for its sponsored subscriptions. Thereafter, WebMD was required to
share 25% of this revenue with Microsoft. In addition, WebMD was required to
share with Microsoft 15% of WebMD's net revenue from e-commerce transactions and
additional services not included in the basic subscription to WebMD's physician
Web site generated by these sponsored subscriptions. There were no obligations
to Microsoft as of December 31, 2000 or 1999 relating to this provision.

     Revised strategic relationship.  To implement the revised relationship, the
parties entered into two definitive agreements. Under the first agreement:

     - Microsoft has agreed to provide performance-based funding tied to the
       roll-out of WebMD's new handheld solution for physicians, which operates
       on a wireless LAN and integrates with the physician's practice management
       system.

     - WebMD has agreed to adopt the PocketPC, Windows 2000 and SQL Server 2000
       as the development platform for our handheld for physicians.

     - WebMD has agreed to make Intergy, our new physician practice management
       system, available to run on Windows 2000 and SQL Server 2000.

     - WebMD has agreed to continue to transition the WebMD.com portal to
       Windows 2000 and SQL Server 2000 when WebMD makes additional investments
       in its portal.

     - Microsoft has agreed to provide consulting services, support and other
       resources in connection with these undertakings.

The term of this agreement is scheduled to expire on December 31, 2004. This
agreement is subject to termination by either party beginning on May 18, 2001 in
the event that the parties have not reached agreement on terms for an
Application Services Agreement, or ASP Agreement, and related documents to
govern deployments by WebMD of Microsoft software on an ASP basis.

     Under the second agreement, WebMD will program the majority of the MSN
health channel, and will have a majority share of revenue derived from
advertising, sponsorship and e-commerce on the MSN health channel site and will
no longer pay carriage fees to Microsoft. The term of this agreement is
scheduled to expire on June 30, 2004.

     As a result of the execution of these agreements, Microsoft will no longer
be responsible for funding the sponsorship of subscriptions to WebMD's physician
portal, and WebMD will not be required to share with Microsoft revenue generated
by physician usage of WebMD's healthcare portals.

     Other.  In connection with the original strategic relationship, Microsoft
acquired shares of common stock and a warrant to purchase shares of common stock
of WebMD, Inc. These securities were converted into securities of our company as
a result of the merger of Healtheon Corporation and WebMD, Inc. in November
1999. As of April 9, 2001, Microsoft owned 11,933,340 shares of our common stock
and a warrant to purchase an additional 13,676,389 shares of our common stock.
The warrant is fully vested and expires on May 12, 2004. Microsoft has
registration rights with respect to the shares that it owns and the shares
issuable upon exercise of its warrant.

  Quintiles

     In connection with our acquisition of Envoy from Quintiles in May 2000, we
entered into a Data Rights Agreement and an Internet Product Development and
Marketing Agreement with Quintiles. Pursuant to the Data Rights Agreement, we
provide certain data to Quintiles through Envoy, which Quintiles uses to provide
market research and related products and services to third parties. The Data
Rights Agreement does not require us to provide data to Quintiles if we are
prohibited from doing so by our contracts with third parties or applicable law.
Data elements that would make the data individually identifiable to a particular
person are required to be removed before the data is provided to Quintiles. The
Data Rights Agreement provides that we are to receive a royalty from Quintiles
based upon the operating income generated from these products. During 2000,
Quintiles did not make any payments to us pursuant

                                        15
<PAGE>   17

to the Data Rights Agreement. Disputes which have arisen with respect to the
obligations of the parties under the Data Rights Agreement are described in
detail in "Legal Proceedings -- Quintiles v. WebMD" on page 24 of our annual
report on Form 10-K.

     The Internet Product Development and Marketing Agreement provides that we
will engage in a collaborative effort with Quintiles to develop, market and
commercialize a portfolio of Internet-based products and services for the
pharmaceutical industry. Quintiles has agreed to pay $100,000,000 for our
development activities and each of us has agreed to share revenue with the other
from the sale of these products and services. During 2000, Quintiles paid us
$929,000 for engineering services. Disputes have arisen with respect to the
obligations of the parties under the Internet Product Development and Marketing
Agreement and we have commenced the dispute resolution procedures provided for
in the Internet Product Development and Marketing Agreement.

  News Corporation

     Pursuant to an agreement signed and publicly announced in December 1999 and
closed in January 2000, WebMD entered into a strategic alliance with The News
Corporation Limited, Fox Entertainment Group and certain of their affiliates,
which we refer to collectively as News Corporation. On December 29, 2000, this
strategic alliance was revised by the parties. The original and revised
strategic relationships are described below.

     Original strategic relationship.  In January 2000, WebMD entered into a
strategic relationship with News Corporation. WebMD received from News
Corporation $100,000,000 in exchange for a 50% interest in a newly formed
international joint venture, WebMD International LLC, domestic and international
advertising and promotion on News Corporation's various properties to be used
over ten years, and a 50% interest in each of The Health Network LLC, a
health-focused cable network, and in Health & Fitness, which operated a
companion Web site, "thehealthnetwork.com." WebMD also entered into a five-year
agreement with News Corporation to provide syndicated, daily broadcast content
for use across various News Corporation properties for cash payments totaling
$12,000,000 annually.

     In connection with the original strategic relationship, we issued News
Corporation 155,951 shares of Series A convertible preferred stock, which were
convertible into 21,282,645 shares of our common stock. In addition, News
Corporation purchased 2,000,000 shares of our common stock for an aggregate
purchase price of $100,000,000.

     Revised strategic relationship.  Under the revised relationship, WebMD
retained the right to receive $205,000,000 in domestic media services over ten
years from News Corporation and will continue to provide content to News
Corporation for use across News Corporation's media properties for the next four
years. News Corporation transferred its 50% interest in WebMD International LLC
to WebMD and was relieved of its commitment to provide any future capital to
WebMD International LLC and its commitment to provide any international media
services. WebMD transferred its interest in The Health Network and Health &
Fitness to News Corporation. WebMD was also relieved of all future capital
commitments to these entities. During 2000, WebMD recognized $21,324,000 in
advertising expense related to the domestic media services provided by News
Corporation and $12,000,000 in revenue for content license fees.

     In connection with the revisions to the relationship, News Corporation
surrendered 155,951 shares of WebMD's Series A convertible preferred stock,
which would have converted into 21,282,645 shares of our common stock. WebMD
granted to News Corporation a warrant to acquire 3,000,000 shares of its common
stock at an exercise price of $15 per share. News Corporation has registration
rights with respect to the shares of common stock issuable upon exercise of the
warrant.

  UnitedHealth Group

     We provide electronic data interchange, or EDI, services through our
ProviderLink and WebMD Practice products to UnitedHealth Group's managed care
providers and customers. We receive a monthly

                                        16
<PAGE>   18

fee for each user site enrolled and a fee per transaction for EDI and
transaction processing services. During 2000, UnitedHealth Group paid us an
aggregate of approximately $19,900,000 related to services, transaction and
license fees. William W. McGuire, M.D., Chief Executive Officer and Chairman of
UnitedHealth Group, was one of our directors until his resignation in January
2000.

  Gleacher & Co.

     Gleacher & Co., formerly Gleacher NatWest, Inc., provided financial
advisory services to WebMD, Inc. prior to the WebMD, Inc. merger and to us after
that merger pursuant to a two-year agreement relating to these services.
Pursuant to that agreement, WebMD, Inc. issued to Gleacher & Co. a warrant to
purchase 1,038,450 shares of its Series D common stock, which we assumed in
connection with the WebMD, Inc. merger. As a result of transfers of portions of
the warrant, Gleacher & Co. currently holds a fully vested warrant to purchase
545,366 shares of our common stock, Luna I Investors, LLC currently holds a
fully vested warrant to purchase 144,231 shares of our common stock, and Eric J.
Gleacher currently holds a fully vested warrant to purchase 418,627 shares of
our common stock, in each case at an exercise price of $8.04 per share. Mr.
Gleacher, who was a member of our board of directors until his resignation in
January 2001, is Chairman and Chief Executive Officer of Gleacher & Co. and a
member of Luna I Investors.

     In 2000, we paid to iXL approximately $356,000 for web development
services. U. Bertram Ellis, Jr., who was a member of our board of directors
until his resignation in September 2000, is the Chairman, Chief Executive
Officer and a stockholder of iXL.

  PTEK Holdings

     We lease space in Atlanta, Georgia from a subsidiary of PTEK Holdings, Inc.
This lease expires in February 2002 and requires monthly payments to PTEK
Holdings of approximately $38,000. We also lease equipment and other personal
property used in our call center from a subsidiary of PTEK Holdings. This lease
expires in February 2002 and requires monthly payments to PTEK Holdings of
approximately $24,000. We provide our subscribers with the option of using PTEK
Holdings' enhanced communications services through our physician portal. Our
agreement with PTEK Holdings is effective until February 2003 and requires
minimum annual payments to PTEK Holdings of $2,500,000 over the term of the
agreement to license its enhanced communications services. The agreement also
requires PTEK Holdings to pay us $1,000,000 per year for exclusivity rights on
our physician portal. In connection with obtaining PTEK Holdings' agreement to
vote for the WebMD, Inc. merger, WebMD, Inc. agreed to use its best efforts to
cause us to honor WebMD, Inc.'s rights and obligations under this agreement,
including provisions regarding exclusivity of telecommunications services.

     William P. Payne, who was one of our directors until his resignation in
September 2000, was Vice Chairman of PTEK Holdings and an employee and the
Chairman of the Board of Orchestrate.com, Inc., a subsidiary of PTEK Holdings.
As Chairman of Orchestrate.com, one of Mr. Payne's principal duties was to
assist us in the development of our business for the purpose of increasing
revenue opportunities for PTEK Holdings. In connection with the WebMD, Inc.
merger, we assumed an agreement between Mr. Payne and WebMD, Inc. effective
until May 2000 pursuant to which, in consideration of Mr. Payne's devotion of up
to 60% of his time directly to our business, we reimbursed PTEK Holdings
$375,000 per year for Mr. Payne's salary, $125,000 per year for Mr. Payne's
minimum bonus and $6,000 per year for Mr. Payne's automobile allowance. We also
reimbursed Mr. Payne for any expenses he incurred prior to that time in
discharging his duties to us.
