adjustments). It is agreed that Two Dollars ($2.00) is the fair market value of
a share as of the effective date hereof. Said Options shall vest and become
exercisable in accordance with the following schedule and shall remain
exercisable through the fourth anniversary of the effective

date of this Agreement, at which time such Options shall expire unless earlier
terminated in accordance with the provisions hereof. Such Options shall include
a provision requiring Executive to execute and deliver a copy of the Restated

         At the effective time and date of a registration statement filed under
the 1993 Act for a public offering of any series of ETI's shares, one-half (1/2)
of the Options held by Executive which then have not vested and become
exercisable under the above vesting schedule will immediately vest and become
exercisable. All Options shall vest and become exercisable upon a Change of
Control of ETI which occurs subsequent to the effective time and date of a
registration statement filed under the Securities Act of 1933 ("1933 Act") for a
public offering of any series of ETI's shares. For purposes of this Section
1.5(a), a "Change of Control" shall mean a change of the possession, direct or
indirect, of the power to direct or cause the direction of management and
policies of ETI, whether through ownership of voting securities, by contract
(other than a commercial contract for goods or non-management services), or
otherwise. Without limitation, a Change of Control shall be deemed to have
occurred if any person or entity that is not on the date hereof the beneficial
owner of any securities of ETI becomes the beneficial owner, directly or
indirectly, of 20% or more of the combined voting power of ETI's outstanding
voting securities ordinarily having the right to vote for the election of
directors of ETI.

         (b)      Return of Options and Repurchase of Shares. (i) In the event
that Executive voluntarily resigns his employment with ETI prior to February 2,
2000, all then outstanding Options that have been issued to Executive shall be
canceled as of the date of Executive's notice of voluntary resignation. In the
event that Executive voluntarily resigns his employment with ETI after February
1, 2000, all then outstanding and exercisable options shall remain exercisable
in full for a period of 120 days after the date of such notice of voluntary
resignation. ETI shall have the option at its sole discretion to purchase any
unexercised Options from the Executive at a price per share equal to the
difference between the exercise price of such Options and the per share

                                     - 3 -
<PAGE>   5

Fair Market Value of the shares of Common Stock underlying such Options
determined as of or before the thirtieth (30th) day following the date such
notice of voluntary resignation was given, with the Fair Market Value of such
shares of Common Stock to be determined in the manner set forth in clause (iv)
of this Subsection 1.5(b) set forth below. Furthermore, in the event Executive
voluntarily resigns his employment with ETI and no registration statement filed
under the 1933 Act for a public offering of any series of ETI's shares has
become effective, then ETI in its sole discretion may purchase any shares of
Common Stock previously obtained by Executive upon his exercise of any Options
for an amount equal to the Fair Market Value of such shares of Common Stock. Any
such repurchase of shares by ETI shall be accomplished within 180 days after
ETI's receipt of such notice of resignation.

                  (ii)     In the event that Executive's employment with ETI
shall be terminated by ETI for Cause after February 1, 1999 or at any time
without Cause, all then outstanding and unexercised Options shall become
exercisable in full as of the date such notice of termination was given by ETI
and shall remain exercisable in full for a period of 120 days after the date
such notice of termination was given. ETI shall have the option at its sole
discretion to purchase any unexercised Options from the Executive at a price per
share equal to the difference between the exercise price of such Options and the
per share Fair Market Value of the shares of Common Stock underlying such
Options determined as of or before the thirtieth (30th) day following the date
such notice of termination was given by ETI, with the Fair Market Value of such
shares of Common Stock to be determined in the manner set forth in clause (iv)
of Subsection 1.5(b) appearing below. Furthermore, if no registration statement
filed under the 1933 Act for a public offering of any series of ETI's Common
Stock has become effective, then ETI in its sole discretion may repurchase any
shares of Common Stock previously obtained by Executive upon the exercise of any
Options for an amount equal to the Fair Market Value of such shares of the
shares of Common Stock. Any such repurchase of the shares of Common Stock shall
be accomplished within 180 days after the date such notice of termination was
given by ETI.

                  (iii)    In the event Executive's employment with ETI shall be
terminated by ETI for Cause on or before February 1, 1999, all then outstanding
Options will be canceled, and, if no registration statement filed under the 1933
Act for a public offering of any series of ETI's Common Stock has become
effective, then ETI in its sole discretion may repurchase any shares of Common
Stock previously obtained by Executive upon his exercise of any Options for an
amount equal to the aggregate amount paid by Executive to ETI in connection with
the exercise price of such Options plus interest at eight percent per annum for
the period Executive owned the Common Stock. Any such repurchase of the shares
of Common Stock shall be accomplished within 180 days after such notice of
termination.

                  (iv)     The Fair Market Value of a share of Common Stock,
Series D on the date specified by ETI shall mean (i) the closing sales price of
the Common Stock of ETI on such date on the national securities exchange
(treating the NASDAQ National Market System as a national securities exchange)
having the greatest volume of trading in the Common Stock during the thirty (30)
day period preceding the day the value is to

                                     - 4 -
<PAGE>   6

be determined or, if such exchange was not open for trading on such date, the
next preceding date on which it was open; (ii) if the Common Stock is not traded
on any national securities exchange, the average of the closing high bid and low
asked prices of the Common Stock on the over-the-counter market, in arms-length
transactions not involving an affiliate of ETI, on the day such value is to be
determined, or in the absence of closing bids on such day, the closing bids on
the next preceding day on which there were bids; (iii) if the Common Stock also
is not traded on the over-the-counter market, the average net proceeds per share
received or the price paid by ETI with respect to shares of Common Stock of any
series sold or purchased by ETI in arms length transactions during the ninety
(90) days preceding the day the value is to be determined; or (iv) if no such
purchase or sale transactions by ETI have occurred within such ninety (90) day
period, the fair market value as determined in good faith by the Board of
Directors of ETI based on (a) such relevant facts as may be available to such
Board, which may include opinions of independent experts, the price at which
recent purchases or sales have been made by third parties, the book value of the
per share, and the ETI's current and future earnings or (b) an independent
appraisal, conducted at ETI's expense, by a qualified financial appraiser who is
reasonably satisfactory to both ETI and Executive, provided that the selection
of method (a) or (b) shall be by mutual agreement of the Board and Executive.

         (c)      Initial Public Offering. In the event that ETI shall undertake
an initial public offering ("IPO") of any series of its stock, pursuant to which
it files a registration statement in accordance with the 1933 Act, notice of the
filing of such registration statement shall be provided to Executive, and upon
the effective date of such registration statement (i) pursuant to and in
accordance with the Restated Shareholders Agreement, each one (1) outstanding
share of Common Stock, Series D will become one (1) share of Common Stock with
all rights of a share of Common Stock, Series A, (ii) pursuant to and in
accordance with Section 1.5(a) above, one-half (1/2) of the Executive's then
unvested Option shall immediately vest and become exercisable, and (iii) ETI
shall have no right to repurchase any shares of Common Stock obtained by his
exercise of any Options.

         Section 1.6       Member of Board. Executive will be elected to the
Board of Directors of ETI at the first regularly scheduled Board meeting
following the effective date hereof.

         Section 1.7       Business Expenses. Executive shall be entitled to
reimbursement of all ordinary and necessary business expenses reasonably
incurred for business travel, communications (including cell phone and pager),
entertainment and meals in connection with the performance of Executive's duties
under this Agreement in accordance with ETI's established policies for
reimbursement of business expenses including an automobile allowance of Five
Hundred Dollars ($500) per month. ETI will also pay the initiation fees,
membership dues and assessments for Executive's family membership in a club in
the Atlanta area acceptable to ETI and Executive which would permit Executive to
engage in business entertainment for the benefit of ETI. ETI expects Executive
to attend and participate in continuing education seminars and courses with
respect to the health industry and business management related to his

                                     - 5 -

acknowledges that all records, files, data, documents and the like relating to
suppliers, customers, costs, prices, systems, methods, personnel, technology and

During the term of his employment with ETI, and for a period of one (1) year
thereafter, Executive shall not directly or indirectly, through one or more
intermediaries or otherwise, solicit, direct or appropriate, or attempt to
solicit, direct or appropriate any individual or entity which was, at the time
of termination of Executive's employment, a customer or client of ETI for the
purpose of providing a service or product to such customer or client which is

at the time of termination of Executive's employment with ETI; provided,
however, that nothing in this Section 2.2 shall prohibit Executive from

                                     - 6 -

acquiring or holding, for investment purposes only, less than five percent (5%)

                            TERMINATION OF EMPLOYMENT

         Section 3.1       Termination by Company. Executive's employment may be
terminated by ETI by giving notice during the term of this Agreement upon the
occurrence of one or more of the following events:

         (a)      Executive's death or disability which renders Executive
incapable of performing his duties for more than one hundred twenty (120)
calendar days in one calendar year or within consecutive calendar years
(termination under this Section 3.1(a) shall be deemed termination without
Cause);

         (b)      for any reason following a determination by the Board of
Directors of ETI to terminate Executive's employment (termination under this
Section 3.1(b) shall be deemed termination without Cause); or

         (c)      "for Cause," which for purposes of this Agreement shall mean
that the Executive shall have committed or engaged in:

                  (i)      an intentional act of fraud, embezzlement or theft in
connection with his duties or in the course of his employment with ETI;

                  (ii)     any intentional wrongful damage to any material

<PAGE>   9

                  (iv)     a felony or any similar crime involving dishonesty or
moral turpitude;

                  (v)      the habitual and debilitating use of alcohol or
drugs; or

                  (vi)     the failure of the Executive to meet performance
expectations, as determined and articulated by a majority of the members of
ETI's Board of Directors other than Executive; provided, however, that in the
event of this clause (vi) being the sole reason for a termination for Cause,
Executive shall have the cure provisions and rights provided for in Section
3.1(d) hereof and clause (ii) of Section 3.2(c) hereof.

         (d)      In the event of a determination by ETI's Board of Directors to
terminate Executive's employment under clause (vi) of Section 3.1(c) based
solely on the failure of Executive to meet performance expectations, then ETI
shall furnish to Executive in writing a notice of proposed termination setting
forth a specific statement of the deficiencies in his performance. Executive
shall then have a period of ninety (90) days after the giving of such written
notice of proposed termination by ETI in which to attempt to effect a cure of
the specified deficiencies. If at the end of such ninety (90) day period no such
cure has been effected to the reasonable satisfaction of the Board of Directors
of ETI, then Executive's employment shall be terminated as of the end of such
ninety (90) day period. ETI shall be obligated to provide to Executive only one
such notice of proposed termination, and if subsequent to effecting a cure of
specified deficiencies the Executive is determined by the Board of Directors to
have again failed to meet performance expectations, then his employment may be
terminated immediately upon ETI's giving of notice of termination to Executive
which specifies his deficiencies in performance.

         Section 3.2       Severance. For purposes of this Agreement,
Executive's entitlement to any severance payments upon termination of his
employment shall be as set forth below:

         (a)      Termination Without Cause. Executive shall be entitled to 12
months salary continuation, payable in bi-weekly installments, and continued
participation in ETI's group health and dental insurance program upon the timely
periodic payment of the amount required by ETI for employees to maintain family
coverage for such programs, as severance pay in the event that the Executive's
employment is terminated without Cause, commencing as of the date of Executive's
death or disability for purposes of Section 3.1(a), or the date specified in a
notice given under Section 3.1(b).

         (b)      Voluntary Termination. Executive shall not receive any
severance pay in the event that he voluntarily resigns his employment with ETI
unless such severance pay is approved by the Board of Directors of ETI in its
sole discretion. Executive shall provide a minimum of thirty (30) days prior
notice to the CEO of his resignation. In the event Executive shall provide
thirty (30) days prior written notice of his intent to resign, ETI may accept
such resignation effective as of any date during such thirty (30) day period as
ETI deems appropriate, provided that Executive shall receive from ETI his salary
and be entitled to participate at ETI's expense in any Company sponsored

                                     - 8 -

benefit programs in which he was a participant as of the effective date of his
resignation for the duration of such thirty (30) day period.

         (c)      For Cause. Executive shall not be entitled to any severance
pay whatsoever in the event that his employment is terminated "for Cause"
pursuant to Section 3.1 (c) of this Agreement, unless (i) severance pay is
approved by the Board of Directors of ETI in its sole discretion, or (ii)
Executive's employment is terminated based solely on nonperformance pursuant to
clause (vi) of Section 3.1(c), in which event Executive shall be entitled to
three (3) months salary continuation and continued participation in ETI's group
health and dental insurance program upon timely periodic payment of the amount
required by ETI for employees to maintain family coverage for such programs.

the application of such provision to any other person or circumstances shall not
be affected, and the provision so held to be invalid, unenforceable or otherwise

Mr. K. Robert Draughon
Healtheon/WebMD Corporation
3399 Peachtree Street NE

Atlanta, Georgia 30326

Dear Rob:

         The purpose of this letter is to evidence the agreement between you and
Healtheon/WebMD Corporation (the "Company") concerning changes to your
employment arrangements with the Company.

         This letter is intended as an amendment to your existing employment
arrangement, whether or not in writing, with the Company or its subsidiaries. To
the extent this letter is inconsistent with those arrangements, this letter will
govern.

         1.       DUTIES AND RESPONSIBILITIES.

         (a)      IN GENERAL. You shall have all of the responsibilities,
duties, powers and authorities which are consistent with your position as
Executive Vice President, Business Development of the Company, and in this
regard shall be responsible for all business development affairs of the Company
and its subsidiaries, and shall have such other reasonable and lawful
responsibilities commensurate with your position as shall be assigned to you by
the Chief Executive Officer of the Company (or Co-Chief Executive Officers, if
there are more than one), all of which shall be consistent with the
responsibilities of similarly situated executives of comparable companies in
similar lines of business.

         (b)      REPORTING RELATIONSHIPS. You will report directly and solely
to the Chief Executive Officer of the Company or Co-Chief Executive Officers if
there shall be more than one. All other employees of the Company and its
subsidiaries whose principal function is the performance of business development
will report directly to you.

         (c)      BASE OF OPERATIONS; RESIDENCE. Your base of operations shall
be in Atlanta, Georgia.

         2.       BASE SALARY; BONUS. Effective on the date hereof your annual
base salary is increased to $450,000, which amount shall be subject to increase
upon periodic review by the

<PAGE>   3

Company. You shall also be entitled to participate in any bonus program
established for the benefit of senior executive officers of the Company.

         3.       ADDITIONAL OPTION GRANTS. On September 12, 2000, the
Compensation Committee of the Board of Directors of the Company granted to you
additional stock options to acquire 250,000 shares of the common stock of the
Company at an exercise price of $16.125 per share (the "New Options"). The New
Options were granted under the Company's 2000 Long-Term Incentive Plan (the
"Plan"), which together with the terms contained in this letter, sets forth the
terms and conditions of the New Options and is incorporated herein by reference.
The New Options are non-qualified stock options and have a term of ten years
from the date of grant. The New Options will vest and become exercisable as to
1/48th of the shares covered thereby on the 12th day each month from October
2000 to and including September 2004, subject to Section 4 below.

         4.       ACCELERATED VESTING AND SEVERANCE COMPENSATION FOLLOWING
TERMINATION. Upon the termination of your employment as a result of the event
described in the first column below, your Equity Compensation (defined below)
shall vest as set forth in the corresponding second column (vesting to include
the waiver of repurchase rights with respect to any restricted stock) and you
shall become entitled to severance compensation and benefits as set forth in the
corresponding third column, except that to the extent that the provisions of the
plans or written agreements under which Equity Compensation has previously been
awarded to you currently provide for vesting, post-termination exercisability,
or severance compensation and benefits more favorable to you than those
described in this Section 4, those provisions shall apply.

</TABLE>

         For purposes of this Section 4, the following definitions shall apply:

         (a)      "Cause" shall mean (i) your willful and continued failure to
                  perform substantially your duties with the Company (other than
                  any such failure resulting from incapacity due to physical or
                  mental illness, and specifically excluding any failure, after
                  reasonable efforts, to meet performance expectations), after a
                  written demand for substantial performance is delivered to you
                  by the Chief Executive Officer or the Board of Directors of
                  the Company which specifically identifies the manner in which
                  the Chief Executive Officer or the Board believes that you
                  have not substantially performed your duties, or (ii) your
                  willful engaging in illegal conduct or gross misconduct which
                  is materially and demonstrably injurious to the Company. For
                  purposes of this provision, no act or failure to act, shall be
                  considered "willful" unless

                                     - 3 -
<PAGE>   5

                  it is done, or omitted to be done, by you in bad faith or
                  without reasonable belief that your action or omission was in
                  the best interests of the Company.

         (b)      "Good Reason" shall mean any of the following, without your
                  written consent, (i) a diminution in your position, authority,
                  duties or responsibilities, (ii) a requirement that you report
                  to any person other than the Chief Executive Officer, or
                  Co-Chief Executive Officers if there are more than one, of the
                  Company, (iii) a reduction in your compensation or fringe
                  benefits, (iv) a breach by the Company of this letter or any
                  other material agreement between you and the Company, or (v) a
                  change in the location from which you are required to perform
                  your services to the Company. If you believe any of the above
                  events or circumstances has occurred, you shall give the
                  Company notice of such event or circumstance. The Company
                  shall have 30 days after such notice to cure any claimed event
                  or circumstance of Good Reason. The Company shall notify you
                  of the timely cure of any claimed event or circumstance of
                  Good Reason and the manner in which such cure was effected,
                  and upon receipt of such written notice of cure from the
                  Company and implementation of an effective cure by the Company
                  within such 30 day period, any notice by you of termination
                  based on such claimed Good Reason shall be deemed withdrawn.

         (c)      "Equity Compensation" shall mean all of your outstanding
                  options to acquire common and other stock of the Company
                  (including without limitation the New Options), all of your
                  restricted stock of the Company, and all of your other
                  contingent compensation subject to vesting, in each case
                  whether currently owned or hereafter acquired by you.

         5.       GROSS-UP PAYMENT.

                  (i)      Anything in this letter to the contrary or any
termination of the Equity Compensation notwithstanding, in the event it shall be
determined that any payment or distribution or benefit received or to be
received by you pursuant to the terms of this letter or any other payment or
distribution or benefit made or provided by the Company, or any of its
subsidiaries and affiliates, to or for your benefit (whether pursuant to this
letter or otherwise and determined without regard to any additional payments
required under this Paragraph 5) (a "Payment") would be subject to the excise
tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended
(the "Code") or any interest or penalties are incurred by you with respect to
such excise tax (such excise tax, together with any such interest and penalties,
is hereinafter collectively referred to as the "Excise Tax"), then you shall be
entitled to receive an additional payment (a "Gross-Up Payment") in an amount
such that after payment by you of all taxes (including any interest or penalties
imposed with respect to such taxes), including, without limitation, any income
and employment taxes (and any interest and penalties imposed with respect
thereto) and the Excise Tax imposed upon the Gross-Up Payment, you retain an
amount of the Gross-Up Payment equal to the sum of (x) the Excise Tax imposed
upon the Payments and (y) the product of any deductions actually disallowed
under Section 68 of the Code solely as a direct result of the inclusion of the
Gross-Up Payment in your adjusted gross income and the highest applicable
marginal rate of federal income taxation for the calendar year in which the
Gross-Up Payment is to be made. For purposes of determining the amount of the
Gross-Up Payment, you shall be deemed to (i) pay federal income taxes at the
highest marginal rates of

                                     - 4 -
<PAGE>   6

federal income taxation for the calendar year in which the Gross-Up Payment is
to be made and (ii) pay applicable state and local income taxes at the highest
marginal rate of taxation for the calendar year in which the Gross-Up Payment is
to be made, net of the maximum reduction in federal income taxes which could be
obtained from deduction of such state and local taxes.

                  (ii)     Subject to the provisions of Paragraphs 5(i) and
5(iii), all determinations required to be made under this Paragraph 5, including
whether and when a Gross-Up Payment is required and the amount of such Gross-Up
Payment and the assumptions to be utilized in arriving at such determination,
shall be made by the Company's certified public accounting firm (the "Accounting
Firm"), which shall provide detailed supporting calculations both to the Company
and you within 15 business days of the receipt of notice from you or the Company
that there has been a Payment, or such earlier time as is requested by the
Company. All fees and expenses of the Accounting Firm shall be borne solely by
the Company. Any Gross-Up Payment, as determined pursuant to this Paragraph 5,
shall be paid by the Company to you within five days of the receipt of the
Accounting Firm's determination. Any determination by the Accounting Firm shall
be binding upon the Company and you. As a result of the uncertainty in the
application of Section 4999 of the Code at the time of the initial determination
by the Accounting Firm hereunder, it is possible that Gross-Up Payments which
will not have been made by the Company should have been made ("Underpayment"),
consistent with the calculations required to be made hereunder. In the event
that the Company exhausts its remedies pursuant to Paragraph 5(iii) and you
thereafter are required to make a payment of any Excise Tax, the Accounting Firm
shall determine the amount of the Underpayment that has occurred and any such
Underpayment shall be promptly paid by the Company to or for your benefit.

                  (iii)    You shall notify the Company in writing of any claim
by the U.S. Internal Revenue Service (the "IRS") that, if successful, would
require the payment by the Company of the Gross-Up Payment. Such notification
shall be given as soon as practicable but no later than ten business days after
you are informed in writing of such claim and shall apprise the Company of the
nature of such claim and the date on which such claim is requested to be paid.
You shall not pay such claim prior to the expiration of the 30-day period
following the date on which you gave such notice to the Company (or such shorter
period ending on the date that any payment of taxes with respect to such claim
is due). If the Company notifies you in writing prior to the expiration of such
period that it desires to contest such claim, you shall:

                  (a)      give the Company any information reasonably requested
by the Company relating to such claim;

                  (b)      take such action in connection with contesting such
claim as the Company shall reasonably request in writing from time to time,
including, without limitation, accepting legal representation with respect to
such claim by an attorney reasonably selected by the Company; and

                  (c)      cooperate with the Company in good faith in order
effectively to contest such claim;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall

                                     - 5 -
<PAGE>   7

indemnify and hold you harmless, on an after-tax basis, for any Excise Tax or
income and employment tax (including interest and penalties with respect
thereto) imposed as a result of such representation and payment of costs and
expenses. Without limitation on the foregoing provisions of this Paragraph
5(iii), the Company shall control all proceedings taken in connection with such
contest and, at its sole option, may pursue or forgo any and all administrative
appeals, proceedings, hearings and conferences with the taxing authority in
respect of such claim and may, at its sole option, either direct you to pay the
tax claimed and sue for a refund or contest the claim in any permissible manner,
and you shall agree to prosecute such contest to a determination before any
administrative tribunal, in a court of initial jurisdiction and in one or more
appellate courts, as the Company shall determine; provided, however, that if the
Company directs you to pay such claim and sue for a refund, the Company shall
advance the amount of such payment to you, on an interest-free basis and shall
indemnify and hold you harmless, on an after-tax basis, from any Excise Tax or
income and employment tax (including interest or penalties with respect thereto)
imposed with respect to such advance or with respect to any imputed income with
respect to such advance; and provided further, that any extension of the statute
of limitations relating to payment of taxes for your taxable year with respect
to which such contested amount is claimed to be due is limited solely to such
contested amount. Furthermore, the Company's control of the contest shall be
limited to issues with respect to which a Gross-Up Payment would be payable
hereunder and you shall be entitled to settle or contest, as the case may be,
any other issue (an "Other Issue") raised by the IRS or any other taxing
authority; provided, however, that if, solely as a result of any contest by the
Company pursuant to this Paragraph 5(iii), your ability to settle or otherwise
resolve any such Other Issue is delayed, then the Company will reimburse you, on
an after-tax basis, for any additional interest incurred by you as a result of
such delay.

                  (iv)     If, after the receipt by you of an amount advanced by
the Company pursuant to Paragraph 5(iii), you becomes entitled to receive any
refund with respect to such claim, you shall (subject to the Company's complying
with the requirements of Paragraph 5(iii) promptly pay to the Company the amount
of such refund (together with any interest paid or credited thereon after taxes
applicable thereto). If, after the receipt by you of an amount advanced by the
Company pursuant to Paragraph 5(iii), a determination is made that you shall not
be entitled to any refund with respect to such claim and the Company does not
notify you in writing of its intent to contest such denial of refund prior to
the expiration of 30 days after such determination, then such advance shall be
forgiven and shall not be required to be repaid and the amount of such advance
shall offset, to the extent thereof, the amount of Gross-Up Payment required to
be paid.

         6.       RESTRICTIONS ON YOUR CONDUCT.

                  (a)      GENERAL. You understand and agree that the purpose of
the provisions of this Paragraph 6 is to protect legitimate business interests
of the Company, as more fully described below, and is not intended to eliminate
your post-employment competition with the Company per se, nor is it intended to
impair or infringe upon your right to work, earn a living, or acquire and
possess property from the fruits of your labor. You hereby acknowledge that the
post-employment restrictions set forth in this Paragraph 6 are reasonable and
that they do not, and will not, unduly impair your ability to earn a living
after the termination of this Agreement. Therefore, subject to the limitations
of reasonableness imposed by law, you shall be subject to the restrictions set
forth in this Paragraph 6.

                           (ii)     Restriction on Relationships with Protected
Customers. You understand and agree that the relationship between the Company
and each of its Protected Customers constitutes a valuable asset of the Company
and may not be converted to your own use. Accordingly, you hereby agrees that,
during the Restricted Period, you shall not, without the prior written consent
of the Company, directly or indirectly, on your own behalf or as a Principal or
Representative of any Person, solicit, divert, take away or attempt to solicit,
divert or take away a Protected Customer for the purpose of providing or selling
Competitive Services; provided, however, that the prohibition of this covenant
shall apply only to Protected Customers with whom you had Material Contact on
the Company's behalf during the twelve (12) months immediately preceding the
termination of your employment. For purposes of this Agreement, you had
"MATERIAL CONTACT" with a Protected Customer if (a) you had direct business

event you breach, or threaten to commit a breach of, any of the provisions of
the Restrictive Covenants, the Company shall have the right and remedy to
enjoin, preliminarily and permanently, you from violating or threatening to
violate the Restrictive Covenants and to have the Restrictive Covenants
specifically enforced by any court of competent jurisdiction, it being agreed
that any breach or threatened breach of the Restrictive Covenants would cause
irreparable injury to the Company and that money damages would not provide an
adequate remedy to the Company. Such right and remedy shall be in addition to,
and not in lieu of, any other rights and remedies available to the Company at
law or in equity. In addition, the Restricted Period shall be extended for the
period of any such breach or threatened breach.

                           (ii)     Severability of Covenants. You acknowledge
and agree that the Restrictive Covenants are reasonable and valid in time and
scope and in all other respects. The covenants set forth in this Agreement shall
be considered and construed as separate and independent covenants. Should any
part or provision of any covenant be held invalid, void or unenforceable in any
court of competent jurisdiction, such invalidity, voidness or unenforceability
shall not render invalid, void or unenforceable any other part or provision of
this Agreement. If any portion of the foregoing provisions is found to be
invalid or unenforceable by a court of competent jurisdiction because its
duration, the territory, the definition of activities or the definition of
information covered is considered to be invalid or unreasonable in scope, the
invalid or unreasonable term shall be redefined, or a new enforceable term
provided, such that the intent of the Company and you in agreeing to the
provisions of this Agreement will not be impaired and the provision in question
shall be enforceable to the fullest extent of the applicable laws.

         7.       MISCELLANEOUS. This letter constitutes the entire agreement
of the parties and shall supercede any and all previous contracts, arrangements
or understandings between the parties relating to the subject matter hereof, and
shall not be amended except in writing signed by each of the parties. This
Agreement shall be governed and construed in accordance with the laws of the
State of Delaware.
