                  shares of common capital stock previously granted to the
                  Employee. The loan is evidenced by a promissory note in such
                  amount and will be secured by the common capital stock
                  granted.

                          3.4.2 PRIVATE OPTIONS. The Employee was previously

                  stock pursuant to the following provisions.

                                    a. The Company agrees to cause its

                          (in addition to 46,384 shares currently owned by the
                          Employee), with the understanding that securities
                          counsel for the Company shall prepare a definitive
                          Stock Option Agreement with such terms and conditions
                          as they deem appropriate, but specifically to include

                                   buy the shares of common capital stock for
                                   the Private Option Price and, if necessary,
                                   that the Company join in such Stock Option
                                   Agreement;

                                   to the Company shall dictate (which may
                                   necessitate a nominal initial consideration
                                   for grant of the options)


                           3.4.3 IPO OPTIONS. In connection with the Company's
                  initial public offering on April 6, 1999, the Employee was

Date, the Chief Executive Officer will review Employee's performance and
compensation hereunder (including salary, bonus, and stock options and/or other
equity incentives) and will approve an increase in such compensation of not less
than 5% annually, but will not have authority, as the result of such review, to
decrease any portion of such compensation without the written consent of
Employee.

         4. CHANGE OF CONTROL. In the event of a Change in Control of the
Company (as defined below), all options then granted to Employee which are
unvested at the date of the Change in Control will be immediately vested. In
addition, in the event of a termination of Employee's employment for any reason
(other than as set forth in Section 5.1(f)) following a Change of Control, the
Company will promptly pay Employee, in addition to the amounts required under
Section 5.2(a), a lump-sum severance amount payable immediately upon such
termination of employment, equal to one-half of his then current annual salary.
This payout shall be in lieu of any amount which may otherwise be due under
Section 5.2(b).

         As used herein, a "Change of Control" of the Company shall be deemed to
have occurred:

         (a) Upon the consummation, in one transaction or a series of related
transactions, of the sale or other transfer of voting power (including voting
power exercisable on a contingent or deferred basis as immediately exercisable
voting power) representing effective control of the Company to a person or group
of related persons who, on the date of this Agreement, is not affiliated (within
the meaning of the Securities Act of 1933) with the Company, whether such sale
or transfer results from a tender offer or otherwise; or

<PAGE>

         (b) Upon the consummation of a merger or consolidation in which the
Company is a constituent corporation and in which the Company's stockholders
immediately prior thereto will beneficially own, immediately thereafter,
securities of the Company or any surviving or new corporation resulting
therefrom having less than a majority of the voting power of the Company or any
such surviving or new corporation; or

         (c) Upon the consummation of a sale, lease, exchange, or other transfer
or disposition by the Company of all or substantially all its assets to any
person or group of related persons.

         5. TERMINATION.

                  5.1 TERMINATION EVENTS. The employment hereunder will
terminate upon the occurrence of any of the following events:

                  (a)   Employee dies;

                  (b) The Company, by written notice to Employee or his personal
representative, discharges Employee due to the inability to perform the duties
assigned to him hereunder for a continuous period exceeding 90 days by reason of
injury, physical or mental illness, or other disability, which condition has
been certified by a physician; provided, however, that prior to discharging
Employee due to such disability, the Company shall give a written statement of
findings to Employee or his personal representative setting forth specifically
the nature of the disability and the resulting performance failures, and
Employee shall have a period of ten (10) days thereafter to respond in writing
to the Company's findings;

                  (c) Employee is discharged by the Company for cause. As used
in this Agreement, the term "cause" shall mean:

                           (i) Employee's conviction of (or pleading guilty or
NO LO CONTENDERE to) a felony or misdemeanor involving dishonesty or moral
turpitude; or

                           (ii) (a) the willful and continued failure of
Employee to substantially perform his duties with the Company (other than any
such failure resulting from illness or disability) after a demand for
substantial performance is requested by the Company's Chief Executive Officer,
which specifically identifies the manner in which it is claimed Employee has not
substantially performed his duties, or (b) Employee is willingly engaged in
misconduct which has a direct and material adverse monetary effect on the
Company. For purposes of this subpart (ii) no act or failure to act on
Employee's part shall be considered "willful" unless done, or omitted to be
done, by Employee not in good faith and without reasonable belief that
Employee's actions were in the best interest of the Company. No termination
shall be effected for cause pursuant to this subpart (ii) unless Employee has
been provided with specific information as to the acts or omissions which form
the basis of the allegation of cause, and Employee has had an opportunity to be
heard, with counsel if he so desires, before the Board of Directors and such
Board determines in good faith that Employee was guilty of conduct constituting
"cause" as herein defined, specifying the particulars thereof in detail;

<PAGE>

                  (d) Employee is discharged by the Chief Executive Officer of
the Company without cause, which the Company may do at any time upon notice to
Employee;

                  (e) Employee voluntarily terminates his employment due to
either (i) a default by the Company in the performance of any of its obligations
hereunder, or (ii) an Adverse Change in Duties (as defined below), which default
or Adverse Change in Duties remains unremedied by the Company for a period of
ten (10) days following its receipt of written notice thereof from Employee; or

                  (f) Employee voluntarily terminates his employment for any
reason other than the Company's default or an Adverse Change in Duties, which
Employee may do at any time with at least 30 days advance written notice.

         As used herein, "Adverse Change in Duties" means an action or series of
actions taken by the Company, without Employee's prior written consent, which
results in:

                  (1) A change in Employee's reporting responsibilities, titles,
job responsibilities, or offices, which, in Employee's reasonable judgment,
results in a diminution of his status, control, or authority;

                  (2) The assignment to Employee of any positions, duties, or
responsibilities which, in Employee's reasonable judgment, are inconsistent with
Employee's positions, duties, and responsibilities or status with the Company;

                  (3) A requirement by the Company that Employee be based or
perform his duties anywhere other than (i) at the Company's corporate office
location on the date of this Agreement, or (ii) if the Company's corporate
office location is moved after the date of this Agreement, at a new location
that is no more than 60 miles from such prior location; or

                  (4) A failure by the Company (i) to continue in effect any
material benefit, whether or not qualified, or other compensation, bonus, or
incentive plan in effect on the date of this Agreement or subsequently adopted,
(ii) to continue Employee's participation in such benefits or plans at the same
level or to the same extent as on the Commencement Date or, with respect to
subsequently adopted benefits or plans, on the date of the initial
implementation thereof, or (iii) to provide for Employee's participation in any
newly adopted benefits or plans at a level commensurate, in Employee's
reasonable judgment, with that of other top executives of the Company.

         5.2 EFFECTS OF TERMINATION.

                  (a) Upon termination of Employee's employment hereunder for
any reason, the Company will promptly pay Employee all compensation owed to
Employee and unpaid through the date of termination (including, without
limitation, salary and employee expense reimbursements).

<PAGE>

                  (b) In addition (except in a situation where severance is due
pursuant to Section 4), if Employee's employment is terminated under Sections
5.1(a), (b), (d), or (e), the Company shall also pay Employee, immediately upon
such termination of employment, a lump-sum severance amount equal to his then
current annual salary.

                  (c) Upon termination of Employee's employment hereunder for
any reason, Employee agrees that for the one year period following the
Termination Event:

                           (i) Employee will not directly or indirectly, whether
for his own account or as an individual, employee, director, consultant, or
advisor, or in any other capacity whatsoever, provide services to any other
person, firm, corporation, or other business enterprise which is involved in
claims processing or other healthcare related matters unless he obtains the
prior written consent of the Chief Executive Officer.

                           (ii) Employee will not directly or indirectly
encourage or solicit, or attempt to encourage or solicit, any individual to
leave the Company's employ for any reason or interfere in any other manner with
the employment relationships at the time existing between the Company and its
current or prospective employees.

                           (iii) Employee will not induce or attempt to induce
any customer, supplier, distributor, licensee, or any other business relation of
the Company to cease doing business with the Company or in any way interfere
with the existing business relationship between any such customer, supplier,
distributor, licensee, or any other business relation and the Company.

         Employee acknowledges that monetary damages may not be sufficient to
compensate the Company for any economic loss which may be incurred by reason of
breach of the foregoing restrictive covenants. Accordingly, in the event of any
such breach, the Company shall, in addition to any remedies available to the
Company at law, be entitled to obtain equitable relief in the form of an
injunction precluding Employee from continuing to engage in such breach.

         If any restriction set forth in this paragraph is held to be
unreasonable, then Employee and the Company agree, and hereby submit, to the
reduction and limitation of such prohibition to such area or period as shall be
deemed reasonable.

substantially all of the Company's assets.
