                          TO BE HELD ON JULY 29, 1998
 
     This Proxy Statement is furnished to holders of the common stock ("Common
Stock") of Medirisk, Inc., a Delaware corporation ("Medirisk" or the "Company"),
in connection with the solicitation of proxies by the Company's Board of
Directors from holders of the outstanding shares of Common Stock at the 1998
Annual Meeting of Stockholders to be held at 10:30 A.M., local time, at the
principal executive offices of the Company at Two Piedmont Center, Suite 400,
3565 Piedmont Road, N.E., Atlanta, Georgia, on Wednesday, July 29, 1998, and at
any adjournments thereof (the "Annual Meeting").
 
     The Annual Meeting will be held for the following purposes:
 
          (i) To elect two persons to serve as directors of the Company;
 
          (ii) To approve the Medirisk, Inc. 1998 Employee Stock Purchase Plan;
 
          (iii) To approve the Medirisk, Inc. 1998 Long-Term Incentive Plan;
 
          (iv) To approve the issuance of Common Stock or Series 1998-A
     Preferred Stock by the Company to the former shareholders of
     Healthdemographics, a corporation recently acquired by the Company, to the
     extent such issuance could result in the Company's issuing more than twenty
     (20%) percent of the issued and outstanding Common Stock of the Company as
     of March 31, 1998, as such approval is required by the listing requirements
     of the Nasdaq Stock Market's National Market (the "Healthdemographics
     Issuance"); and
 
          (v) To consider and act upon such other business as may properly come
     before the Annual Meeting or any adjournments thereof.
 
     This Proxy Statement and the accompanying Proxy are first being mailed to
stockholders of the Company on or about June   , 1998. The Company's Annual
Report for the fiscal year ended December 31, 1997, including financial
statements, is being sent to stockholders with this Proxy Statement.
 
STOCKHOLDERS ENTITLED TO VOTE
 
     Only record holders of the Common Stock at the close of business on June
19, 1998 (the "Record Date") will be entitled to notice of, and to vote at, the
Annual Meeting. On the Record Date there were [     ] shares of Common Stock
issued and outstanding held by approximately [     ] stockholders of record.
Notwithstanding the Record Date specified above, the Company's stock transfer
books will not be closed, and shares may be transferred after the Record Date.
However, all votes must be cast in the names of stockholders of record on the
Record Date.
 
QUORUM AND VOTING REQUIREMENTS
 
     Pursuant to the Company's Certificate of Incorporation, as amended (the
"Certificate of Incorporation"), holders of Common Stock will be entitled to one
vote for each share held. The election of directors requires the affirmative
vote of a plurality of the shares of Common Stock represented and entitled to
vote at the Annual Meeting, provided a quorum is present; therefore, abstentions
and "broker nonvotes" (which occur when shares held by brokers or nominees for
beneficial owners are voted on some matters but not on others) will have no
effect. With respect to the election of directors, stockholders may (i) vote in
favor of both of the nominees, (ii) withhold authority to vote for both of the
nominees or (iii) withhold authority to vote for one of the nominees, but vote
in favor of the other nominee. Pursuant to the Company's Bylaws (the "Bylaws"),
a
 
                                        1
<PAGE>   5
 
majority of the shares of Common Stock must be present to establish a quorum.
For purposes of determining the presence of a quorum, abstentions will be
counted as present, but broker nonvotes will not be counted.
 
     The Company believes that approximately [     ] shares owned or controlled
on the Record Date by the directors and executive officers of the Company (or by
companies or funds affiliated with directors of the Company), constituting
approximately [     .     ]% of the outstanding Common Stock, will be voted in
favor of each of the proposals.
 
     The approval of each of the Medirisk, Inc. 1998 Employee Stock Purchase
Plan (the "Employee Stock Purchase Plan"), the Medirisk, Inc. 1998 Long-Term
Incentive Plan (the "Long-Term Incentive Plan") and the Healthdemographics
Issuance requires the affirmative vote of a majority of the shares of Common
Stock represented and entitled to vote at the Annual Meeting, provided a quorum
is present; therefore, abstentions and "broker nonvotes" will have no effect.
With respect to the approval of each of the Employee Stock Purchase Plan, the
Long-Term Incentive Plan and the Healthdemographics Issuance, stockholders may
(i) vote for the approval of such plan and/or issuance, (ii) vote against such
plan and/or issuance or (iii) abstain.
 
PROXIES
 
     If the enclosed Proxy is executed, returned in time and not revoked, the
shares represented thereby will be voted in accordance with the instructions
indicated in such Proxy. IF NO INSTRUCTIONS ARE INDICATED, PROXIES WILL BE VOTED
(I) FOR THE ELECTION OF BOTH NOMINEES FOR DIRECTOR OF THE COMPANY, (II) FOR THE
APPROVAL OF THE MEDIRISK, INC. 1998 EMPLOYEE STOCK PURCHASE PLAN, (III) FOR THE
APPROVAL OF THE MEDIRISK, INC. 1998 LONG-TERM INCENTIVE PLAN, (IV) FOR THE
APPROVAL OF THE HEALTHDEMOGRAPHICS ISSUANCE, AND (V) IN THE BEST JUDGMENT OF
SUCH PROXIES AS TO ANY OTHER MATTERS WHICH MAY PROPERLY COME BEFORE THE ANNUAL
MEETING OR ANY ADJOURNMENTS THEREOF.
 
     A stockholder who has given a Proxy may revoke it at any time prior to its
exercise at the Annual Meeting by either (i) giving written notice of revocation
to the Secretary of the Company, (ii) properly submitting to the Company a duly
executed Proxy bearing a later date, or (iii) appearing at the Annual Meeting

                                   PROPOSAL 1
                             ELECTION OF DIRECTORS
 
     The Company's Bylaws provide that the Company's Board of Directors shall
consist of not less than three and not more than twelve individuals, with the
exact number to be determined by resolution of a majority of the Board of
Directors. The Board of Directors has by resolution set the number of directors
at six. The Company's Bylaws provide that the Board of Directors shall consist
of three classes of directors serving staggered terms of office, with each class
to consist, as nearly as possible, of one-third of the total number of directors
constituting the entire Board of Directors. Upon the expiration of the term of
office for a class of directors, the nominees for that class will be elected for
a three-year term to serve until the election and qualification of their
successors. The two current Class 2 directors, Michael J. Finn and James K.
Murray, III, have been nominated for re-election at the Annual Meeting for a
three-year term. The Class 3 and Class 1 directors, named below, have one year
and two years, respectively, remaining on their terms of office and will not be
voted upon at the Annual Meeting.
 
     It is the intention of the persons named as proxies to vote the Proxies for
election of each of Mr. Finn and Mr. Murray as a Class 2 director of the
Company, unless stockholders direct otherwise in their Proxies. Each Class 2
director will be elected to hold office until the 2001 Annual Meeting of
Stockholders or until his earlier death, resignation or removal. Each of Mr.
Finn and Mr. Murray has consented to continue to serve as a director of the
Company if re-elected. In the unanticipated event that Mr. Finn or Mr. Murray
refuses or is unable to serve as a director, the Board of Directors, in its
discretion, may designate a substitute nominee or nominees (in which case the
persons named as proxies will vote all valid Proxies for the election of such
substitute nominee or nominees), allow the vacancy or vacancies to remain open
until the Board locates a suitable candidate or candidates or by resolution
reduce the authorized number of directors. The Board of Directors has no reason
to believe that either of the nominees will be unable or will decline to serve
as a director.

bonuses and other compensation for the Company's executive officers and for
administering the Company's Stock Incentive Plans (other than the Medirisk, Inc.

Committee did not formally meet, but took action by written consent on five

     Nonmanagement Directors' Stock Option Plan Committee.  The Nonmanagement
Directors' Stock Option Plan Committee, which is comprised of Messrs. Kaiser and

     The Board of Directors as a whole functions as the nominating committee to
select management's nominees for election as directors of the Company. The Board
of Directors will consider nominees submitted
 
                                        6
<PAGE>   10

     During 1997, the Board of Directors met five times. Each director, during
the period he was a director, attended at least 75% of the meetings of the Board
of Directors and at least 75% of the total number of all meetings of all of the
committees on which he served.
 
DIRECTOR COMPENSATION
 
     Members of the Board of Directors who are not officers of the Company
receive (i) an annual retainer of $5,000; (ii) a fee of $1,000 for each meeting
of the Board of Directors that such member attends in person; (iii) a fee of
$250 for each meeting of the Board of Directors that such member attends by
telephone; and (iv) a fee of $250 for each meeting of a committee of the Board
of Directors that such member attends in person or by telephone.
 
     The Company has also established the Medirisk, Inc. Nonmanagement
Directors' Stock Option Plan (the "Directors' Plan"), which provides for the
issuance of nonqualified stock options to directors of the Company who are not
employed by the Company. Messrs. Cowan, Finn, Murray and Pinkas and Dr.
McClatchey are eligible to participate in the Directors Plan. Pursuant to the
Directors' Plan, in 1997 each eligible director received an initial grant of
10,000 options upon the completion of the Company's initial public offering at a
price equal to $11.00, the initial public offering price, and a further grant of
5,000 options on December 31, 1997, at a price also equal to $11.00, which was
the per share closing price on that date for shares of Common Stock on the
Nasdaq National Market. The Directors' Plan provides that each eligible director
who is first elected or appointed to serve as a director following the Company's
initial public offering will be granted an option as of the first business day
following his or her first day of service as a director to purchase 10,000
shares of Common Stock. An option granted under either of the foregoing
circumstances is hereinafter referred to as an "Initial Option." Thereafter,
each eligible director will be granted as of the last business day of each
fiscal year an option to purchase 5,000 shares of Common Stock (an "Annual
Option"), provided that the eligible director continues to serve as director as
of the last business day of that fiscal year. In addition, each eligible
director will be granted, as of the date of exercise of any Initial Option or
Annual Option, an option to purchase a number of shares equal to the number, if
any, of the shares of Common Stock tendered in payment of the exercise price as
described below, provided that the optionee is a member of the Board of
Directors as of the exercise date. No options will be granted to an eligible
director who is otherwise precluded from receiving a grant of Common Stock. If
the remaining number of shares reserved for issuance under the Directors' Plan
is insufficient to grant options for the appropriate number of shares to all
eligible directors as of any grant date, then no options will be granted as of
that grant date.
 
     The exercise price of an option will be equal to the fair market value of a
share of Common Stock on the date of grant. All options granted under the
Directors' Plan will become exercisable in one-third increments over three years
following the date of grant, provided, however, that in the event of a
director's death or disability, any such option will become exercisable
immediately in full upon the later of (i) the optionee's death or disability or
(ii) six months following the date of grant. The Directors' Plan is administered
by the Nonmanagement Directors' Stock Option Plan Committee.

Plan, awards are permitted to be granted in the form of nonqualified stock
options, incentive stock options, stock appreciation rights and shares of
restricted stock. In addition, the 1996 Incentive Plan provides for several
types of equity-based incentive compensation awards, namely performance units,
performance shares, phantom stock, unrestricted bonus stock and dividend
equivalent rights.
 
     The 1996 Incentive Plan will be administered by the Compensation Committee
of the Board of Directors. The Compensation Committee will determine the persons
to whom, and the times at which, awards will be granted, the type of awards to
be granted and all other related terms and conditions of the awards, subject to
certain limitations set forth in the 1996 Incentive Plan. All officers and key
employees of the Company and its affiliates are eligible to participate in the
1996 Incentive Plan.
 
     A total of 580,645 shares of Common Stock are reserved for issuance
pursuant to the 1996 Incentive Plan. In the event of a Change in Control of the
Company (as defined in the 1996 Incentive Plan), stock incentives will become
fully vested without regard to the exercisability of the award or any other
conditions or restrictions. In connection with the Company's initial public
offering, the Company caused all then-existing outstanding options (which had
not been issued under any plan) to be surrendered in exchange for options with
identical terms issued under the 1996 Incentive Plan. As of March 24, 1998,
there were options for 523,023 shares of Common Stock outstanding under the 1996
Incentive Plan.
 
     Medirisk Nonmanagement Directors' Stock Option Plan.  The Medirisk, Inc.
Nonmanagement Directors' Stock Option Plan provides for the issuance of
nonqualified stock options to directors of the Company who are not employed by
or otherwise affiliated with the Company ("eligible" directors). A total of
100,000 shares of Common Stock are reserved for issuance pursuant to the
Directors' Plan. The effective date of the Directors' Plan (the "Effective
Date") was January 28, 1997, the effective date of the Company's initial public
offering. See "Director Compensation."
 
     New Plans.  The Board of Directors has adopted, subject to stockholder
approval, the Medirisk, Inc. 1998 Employee Stock Purchase Plan and the Medirisk,
Inc. 1998 Long-Term Incentive Plan. Descriptions of such plans appear below
under Proposal 2 - "Approval of the Medirisk, Inc. 1998 Employee Stock Purchase
Plan" and Proposal 3 - "Approval of the Medirisk, Inc. 1998 Long-Term Incentive
Plan."

EMPLOYMENT AGREEMENT
 
     Mark A. Kaiser is a party to an employment agreement dated as of May 31,
1996, with Medirisk pursuant to which he serves as Chairman of the Board of
Directors and Chief Executive Officer of the Company (the "Employment
Agreement"). The Employment Agreement is for an initial term of three years,
commencing on May 31, 1996, with automatic one-year renewals thereafter, unless
either party gives 60 days' advance notice of nonrenewal. The Employment
Agreement provides for an initial annual base salary of $190,000, which may be
increased annually at the discretion of the Compensation Committee of the
Company, and an annual target bonus equal to 50% of his base salary for the
applicable year, determined based upon Medirisk's performance with respect to
goals established by the Compensation Committee. Mr. Kaiser is also entitled to
participate in all of the Company's employee benefit plans. In addition, under
the Employment Agreement Mr. Kaiser was granted options to purchase up to 32,480
shares of Common Stock at $0.64 per share in 1996 and an additional 32,480
shares of Common Stock at $7.50 per share in May 1997. The Employment Agreement
provides that the Company shall grant Mr. Kaiser additional options to purchase
32,480 shares on each of the first and second anniversaries of the date of the
agreement. These subsequent options will have an exercise price equal to the
fair market value of the Common Stock on the date of grant. All of the options
granted under the Employment Agreement vest ratably over five years from the
date of grant or immediately upon the sale or other change of control involving
the Company. The Employment Agreement contains a nondisclosure covenant, as well
as covenants not to divert business or employees from the Company for one year
following termination. In the event Mr. Kaiser terminates his employment for
good reason, as defined in the Employment Agreement (which includes a voluntary
termination by Mr. Kaiser one year after a change of control involving the
Company), or if Medirisk terminates his employment other than for good cause, as
defined in the Employment Agreement, Mr. Kaiser shall be entitled to continue to
receive his base salary and all benefits until the later of May 31, 1999, or one
year from the date of termination.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     James K. Murray, III, was a member of the Compensation Committee for a
portion of 1997, during which period he was also an Executive Vice President of
HPSC. Prior to Mr. Murray's joining the Board of Directors, the Company and HPSC
entered into a Securities Purchase Agreement, (the "Securities Purchase
Agreement") pursuant to which the Company issued to HPSC 280,623 shares of
Series B Convertible Preferred Stock for $2.0 million and Senior Subordinated
Notes in an original principal amount equal to $6.9 million at par. At that
time, the Company and HPSC entered into a Registration Rights Agreement giving
HPSC certain demand and piggyback registration rights, a Shareholders' Agreement
and Warrant Agreement. Pursuant to the Securities Purchase Agreement, HPSC has
the right to name one person to be nominated to the Company's Board of Directors
so long as HPSC owns or has the right to acquire at least 162,400 shares of
Common Stock. In connection with the Company's initial public offering, during
1997 the Company repaid the HPSC Senior Subordinated Notes, and the Series B
Convertible Preferred Stock was automatically converted into 182,292 shares of
Common Stock.
 
         REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS
 
     Decisions and recommendations regarding the compensation of the Company's
executives are made by the Compensation Committee which is composed entirely of
directors who do not serve as officers or employees of the Company. Set forth
below is a report of the members of the Compensation Committee during 1997
concerning the Company's compensation policies for 1997. The following report is
not subject to incorporation by reference in any filings heretofore or hereafter
made by the Company under the Securities Act of 1933, as amended, or the
Securities Exchange Act of 1934, as amended.
 
     Prior to the Company's initial public offering, the Compensation Committee
was comprised of Messrs. Pinkas, Finn and Murray. From February 4, 1997 through
December 31, 1997, the Committee was comprised of Messrs. Pinkas and Cowan.
 
                                       11
<PAGE>   15
 
     The Compensation Committee of the Board of Directors establishes
compensation policies and programs for the Company's Chief Executive Officer and
other senior management. The Compensation Committee establishes base
compensation (subject to any employment agreements that are in place), approves
increases in base compensation and determines bonus compensation (subject to any
employment agreements that are in place) for the Company's Chairman of the Board
and Chief Executive Officer and its Chief Financial Officer and has authority to
approve the recommendations of senior management regarding annual base and bonus
compensation for all other officers and senior employees of the Company. The
Compensation Committee also has exclusive authority to approve stock option (and
other stock incentive) grants to all executive officers and employees. The
Compensation Committee considers both internal and external data in determining
officers' compensation, including relevant industry executive compensation data.
 
COMPENSATION PHILOSOPHY
 
     The Company's compensation philosophy is for a substantial portion of the
annual compensation of each executive officer to be contingent on the
performance of the Company, as well as the individual contributions of each
officer. As a result, much of each executive officer's compensation is "at
risk," with annual bonus compensation (upon attaining 100% or more of target
levels) accounting for not less than 20% of total cash compensation for senior
management. The purpose of this philosophy is to align the executive's
compensation closely with the Company's achievement of both annual and
long-range objectives, thereby serving the interests of stockholders. The
Company also seeks to provide competitive compensation packages when compared to
companies of a similar size in similar industries, which assists the Company in
attracting and retaining highly qualified executives.
 
COMPENSATION PROGRAM
 
     The Company's executive compensation program has three major components,
all of which are intended to implement the Company's compensation philosophy:
 
          1. Base Salary.  Base annual salary for the Chairman of the Board and
     Chief Executive Officer is established by employment contract and is
     reviewed annually. Base salary for other executive officers is established
     when the officer is employed and is reviewed annually. In establishing and
     reviewing base salaries, the Compensation Committee bases its decisions on
     competitive pay practices of comparable companies, the skills and
     performance of the individual executive, the needs and resources of the
     Company, and the expenses that would be incurred by the Company in
     recruiting a new executive to fill a vacated position.
 
          2. Cash Bonuses.  The Company makes annual cash bonuses available to
     its senior management based upon the attainment of specified business and
     personal goals. Bonuses paid in 1997 were based on executives' performance
     in 1996, and the amounts of such bonuses were based on the Compensation
     Committee's subjective assessment of the Company's and the executive's
     performance in 1996.
 
          In 1997, the Compensation Committee adopted an incentive compensation
     program for the Company's executive officers (Messrs. Kaiser, Goins and
     Rodwick). The program was intended to provide cash incentive bonuses based
     on the Company's achievement of short-term goals that were consistent with
     the Company's long-term goals and to promote the Company's compensation
     philosophy that a substantial portion of executive compensation be at risk.
     It was the Compensation Committee's subjective assessment that an incentive
     bonus equal to 50% of base salary (the level established for Mr. Kaiser in
     his employment agreement) was an appropriate percentage for all executive
     officers to have at risk on an annual basis. The annual bonus under the
     incentive compensation program was to be based on the Company's performance
     measured by targeted earnings-per-share for 1997. If the actual performance
     for 1997 was less than the target, the bonus would be reduced, and if the
     actual performance for 1997 was greater than the target, the bonus would be
     increased. The Company met the earnings-per-share targets established in
     the 1997 incentive compensation program, and bonuses will be paid to
     Messrs. Kaiser and Goins in 1998 in accordance with the program. In light
     of his resignation, Mr. Rodwick will not receive any bonus under the 1997
     incentive compensation program.
 
                                       12
<PAGE>   16
 
          The Compensation Committee has adopted a similar incentive
     compensation plan for Messrs. Kaiser, Goins and Rawls for the year 1998.
 
          3. Equity-Based Incentive Compensation.  The Company provides
     equity-based incentives to key employees through the Medirisk, Inc. 1996
     Stock 1996 Incentive Plan (the "1996 Incentive Plan"). The 1996 Incentive
     Plan is administered by the Compensation Committee. As a general practice,
     the Compensation Committee approves grants of stock options to key
     employees commensurate with their positions when they join the Company and
     considers additional discretionary grants on an annual basis based on
     performance.
 
     All options granted since the Company's initial public offering in January
1997 (including the options granted in 1997 to Messrs. Kaiser and Goins, as
discussed below) have been granted with an exercise price equal to the fair
market value of the Common Stock on the date of grant (with fair market value
being equal to the closing price of a share of Common Stock as quoted on the
Nasdaq National Market). The Compensation Committee believes that this pricing
practice will generally continue in the future. Historically, all options have
vested over five years from the date of grant to provide incentive to key
employees to remain with the Company, and the Compensation Committee intends to
continue this practice. The Compensation Committee has the authority to shorten
this vesting period in its discretion. The purpose of the 1996 Incentive Plan is
to provide the economic incentives of ownership, create management incentives to
improve stockholder value and, through the use of vesting periods, to encourage
executives to remain with the Company and focus on long-term results. The
Company has not granted stock appreciation rights, restricted stock awards or
long-term incentive bonuses, but the 1996 Incentive Plan permits grants of these
types of incentives.
 
     The Company and Mark A. Kaiser, Chairman of the Board, Chief Executive
Officer and President of the Company, entered into a three-year Employment
Agreement effective on May 31, 1996. As required by that Employment Agreement,
on June 2, 1997, the Company granted 32,480 options to Mr. Kaiser with an
exercise price of $7.50 per share. The Employment Agreement also requires the
Company to grant an additional 32,480 options on May 31, 1998. During 1997 the
Compensation Committee also approved grants of a total of 42,520 options to
Kenneth M. Goins, Jr., Executive Vice President and Chief Financial Officer of
the Company, 16,240 of which have an exercise price of $7.625 per share, and the
remaining 26,280 of which have an exercise price of $10.50 per share. All
options granted to Messrs. Kaiser and Goins in 1997 vest over five years from
the date of grant, subject to acceleration upon a change in control of the
Company.
 
OTHER EXECUTIVE COMPENSATION
 
     The Company's executives also participate in the benefit programs that are
available to all of the Company's employees, including a 401(k) savings plan
(which permits matching contributions), medical, and life and disability
insurance benefits. The Company does not maintain any other pension or
retirement programs. The Company generally does not provide executive
perquisites such as club memberships.
 
     The Securities and Exchange Commission requires all Compensation Committees
to discuss how they intend to deal with the cap on deductibility of compensation
over $1.0 million for executive officers. Given the Company's current
compensation levels, the Compensation Committee does not believe it is necessary
to consider this issue at this time. The Company intends to take necessary steps
to ensure that its compensation policies maximize the deductibility of
compensation paid to executives; however, the Compensation Committee may
determine that nondeductible payments are appropriate in light of a particular
executive's performance or particular circumstances.
 
CHIEF EXECUTIVE OFFICER'S COMPENSATION
 
     Mr. Kaiser's 1997 compensation was derived from commitments under his
Employment Agreement. The Compensation Committee approved a discretionary
increase in Mr. Kaiser's base salary to $202,000 (a 6.3% increase over his prior
base salary for 1996) in February 1997. In approving such increase, the
Compensation Committee considered its experience with, and knowledge of, the
compensation of chief executive officers of similar companies, as well as Mr.
Kaiser's importance to the Company and its operations. At that time Mr. Kaiser
also received bonus compensation of $95,000 (which represented 50% of his 1996
base salary) in
                                       13
<PAGE>   17
 
recognition of his efforts in overseeing and completing the Company's initial
public offering and the implementation of the Company's 1996 operating plan. Mr.
Kaiser's target annual bonus of 50% of base salary is established in the
Employment Agreement. The Employment Agreement also provides that the amount of
bonus is determined upon the Company's performance with respect to goals
established by the Compensation Committee. Pursuant to the Employment Agreement,
the Company granted Mr. Kaiser 32,480 options in June 1997 as discussed above.
When it approved the Employment Agreement, the Compensation Committee determined
that these additional equity-based compensation awards were necessary for the
retention of Mr. Kaiser and to provide added incentive to achieve the Company's
short-term and long-term goals.

                       1998 EMPLOYEE STOCK PURCHASE PLAN
 
     The Board of Directors on March 11, 1998 adopted, subject to stockholder
approval at the Annual Meeting, the Medirisk, Inc. 1998 Employee Stock Purchase
Plan (the "Employee Stock Purchase Plan"). If approved by the stockholders at
the Annual Meeting, the Employee Stock Purchase Plan will be effective as of its
adoption by the stockholders.
 
     A summary of the Employee Stock Purchase Plan is set forth below. The
summary is qualified in its entirety by reference to the full text of the
Employee Stock Purchase Plan attached to this Proxy Statement as Exhibit "A."
 
                                       15
<PAGE>   19
 
GENERAL
 
     The purpose of the Employee Stock Purchase Plan is to encourage employees
of the Company and any participating subsidiaries to acquire a proprietary
interest, or to increase their existing proprietary interest, in the Company.
The Board of Directors believes that employee ownership of the Company's Common
Stock will serve as an incentive, encouraging employees to continue employment
and to perform diligently their duties as employees.
 
     The Employee Stock Purchase Plan is proposed to be adopted with 200,000
shares available for purchase.
 
ELIGIBILITY
 
     Each employee of the Company and each employee of any designated subsidiary
corporation of the Company that has adopted the Employee Stock Purchase Plan for
the benefit of its employees (the Company and each such other corporation being
referred to herein as a "Participating Company") is eligible to participate in
the Employee Stock Purchase Plan, provided such employee: (i) is regularly
scheduled to work at least twenty (20) hours each week and at least five (5)
months in the calendar year, and (ii) immediately after the grant of an option
to him under the Employee Stock Purchase Plan would own less than five percent
of the total combined voting power or value of all classes of stock of the
Company or any of its subsidiaries. As of June 10, 1998, there were
approximately 245 employees eligible to participate in the Employee Stock
Purchase Plan.
 
     An eligible employee may elect to become a participant in the Employee
Stock Purchase Plan by filing with the Compensation Committee of the Board of
Directors of the Company an election form authorizing specified regular payroll
deductions over the next succeeding purchase period. Unless an employee files a
new election form or withdraws from the Employee Stock Purchase Plan, the
election form continues from one purchase period to succeeding purchase periods
as long as the Employee Stock Purchase Plan remains in effect. An employee may
authorize payroll deductions in an amount not less than one (1%) percent but not
more than ten (10%) percent of the employee's total compensation, including base
pay or salary and any bonuses or commissions. Deductions may not be increased or
decreased during a purchase period, but a participant may withdraw in full from
the Employee Stock Purchase Plan at any time. A participant may not make cash
contributions or payments to the Employee Stock Purchase Plan.
 
ADMINISTRATION
 
     The Compensation Committee of the Board of Directors will have the
authority to interpret and construe all provisions of the Employee Stock
Purchase Plan and will have general responsibility for the administration of the
Plan, including the authority to appoint an administrator for the Plan (the
"ESPP Administrator").
 
SHARES SUBJECT TO PLAN
 
     Shares subject to the Employee Stock Purchase Plan may be authorized but
unissued shares or shares that were once issued and subsequently reacquired by
the Company. The total number of shares of Common Stock for which options may be
granted under the Employee Stock Purchase Plan is 200,000 shares, subject to
adjustment in accordance with the Employee Stock Purchase Plan.
 
TERMS AND CONDITIONS OF PARTICIPATION
 
     Participant Accounts.  The ESPP Administrator will establish a bookkeeping
account for each participant and credit such participant's payroll deductions to
his account. Any funds actually held in accounts will remain part of the general
assets of the Company and may be used by the Company for any corporate purpose.
No interest will accrue or be paid on any payroll deductions contributed to the
Employee Stock Purchase Plan or credited to the account of any participant.
 
     Purchase Periods.  Under the Employee Stock Purchase Plan, the purchase
periods during which payroll deductions will be accumulated under the Employee
Stock Purchase Plan are the three-month periods commencing on or about January
1, April 1, July 1 and October 1 of each calendar year. The first purchase
                                       16
<PAGE>   20
 
period commencing after the effective date of the Employee Stock Purchase Plan
will be the three-month period from October 1, 1998, through December 31, 1998.
 
     Grant of Options.  On the first business day of each purchase period, the
Company will grant to each participant in the Employee Stock Purchase Plan an
option to purchase on the last day of such purchase period whole shares of
Common Stock. The participant will be entitled to exercise such option to the
extent of the participant's accumulated payroll deductions on the last day of
such purchase period; provided, however, that the maximum number of shares of
Common Stock that the participant will be eligible to purchase with respect to
each of the first four purchase periods is 1,250 shares per period. If the
participant's accumulated payroll deductions on the last day of each of the
initial four purchase periods would enable the participant to purchase more than
1,250 shares with respect to such period, the excess of the amount of the
accumulated payroll deductions over the aggregate purchase price of the 1,250
shares will be refunded to the participant, without interest. The Option Price
for each purchase period will be the lesser of (i) 85% of the fair market value
of the Common Stock on the first business day of the purchase period, or (ii)
85% of the fair market value of the Common Stock on the last business day of the
purchase period.
 
     Exercise of Options.  Each eligible employee who continues to be a
participant in the Employee Stock Purchase Plan on the last business day of a
purchase period will be deemed to have exercised his option on such date for
such number of full shares of Common Stock as his accumulated payroll deductions
on such date will pay for at the Option Price, subject to the 1,250-share limit
of the option for each of the first four purchase periods. Only full shares of
Common Stock may be purchased under the Employee Stock Purchase Plan. Unused
payroll deductions remaining in an employee's account at the end of a purchase
period (other than amounts refunded to the employee as set forth above) will be
carried forward to the succeeding purchase period, without interest.
 
     Special Limitations.  No option will be granted to a participant if such
option, when combined with all other options granted under all of the Code,
employee stock purchase plans of the Company maintained in accordance with
Section 423 of the Code, its parents and its subsidiary corporations, would
permit such participant to purchase shares of Common Stock of the Company having
a fair market value in excess of $25,000 per year.
 
     Withdrawals.  An employee may withdraw from the Employee Stock Purchase
Plan at any time prior to the last business day of each purchase period by
delivering a withdrawal notice to the ESPP Administrator, in which event the
Company will refund the entire balance of the employee's deductions not
previously used to purchase stock under the Employee Stock Purchase Plan. To
re-enter the Employee Stock Purchase Plan, an employee who has previously
withdrawn must file a new authorization at least ten (10) days before the
beginning date of the next purchase period. A participant who elects to withdraw
from the Employee Stock Purchase Plan may not participate again until the
beginning of the next purchase period.
 
     Adjustments.  If the shares of Common Stock are subdivided or combined into
a greater or smaller number of shares or if, upon a reorganization, split-up,
liquidation, recapitalization or the like of the Company, shares of Common Stock
are exchanged for other securities of the Company, each optionee will be
entitled to purchase such number of shares of Common Stock or amount of other
securities of the Company as were exchangeable for the number of shares of
Common Stock such optionee would otherwise have been entitled to purchase, and
appropriate adjustments will be made in the exercise price per share to reflect
such subdivision, combination or exchange. In the event of a stock dividend,
each optionee upon exercising such an option will be entitled to receive the
shares as to which he or she is exercising the option and the stock dividend on
such shares. In any of the above events, appropriate adjustments will also be
made to the number of shares available for purchase under the Employee Stock
Purchase Plan. Any of the above adjustments will be made only to the extent that
they will not require stockholder approval under Section 423(b)(2) of the Code.
In the event of an acquisition of the Company or substantially all of its stock
or assets, each optionee shall be entitled to receive at the end of the
applicable purchase period, upon the exercise of such purchase right for each
share Common Stock as to which such purchase right shall be exercised, as nearly
as reasonably may be determined, the cash, securities, or property which a
holder of one (1) share of the Common Stock was entitled to receive upon and at
the time of such transaction. The Board of Directors will take such steps in
connection with such
 
                                       17
<PAGE>   21
 
transactions as the Board deems necessary or appropriate to assure that the
foregoing provision shall thereafter be applicable, as nearly as reasonably may
be determined, in relation to the cash, securities, or property which the holder
of such purchase right may thereafter be entitled to receive. In lieu of the
foregoing, the Compensation Committee may terminate the Employee Stock Purchase
Plan in accordance with the terms thereof.
 
     Delivery of Common Stock; Stockholder Rights.  As soon as practicable after
the end of each purchase period, the Company will issue to each participant the
shares of Common Stock of the Company, if any, purchased for such participant.
During such time, if any, as the Company participates in a direct registration
system, shares of Common Stock so issued shall be directly registered in the
name of the participant. If the Company does not participate in a direct
registration system, then until distribution of the shares from the Employee
Stock Purchase Plan is requested by a participant, stock certificates evidencing
the participant's shares of Common Stock acquired upon exercise of a Purchase
Right shall be held by the ESPP Administrator as the nominee for the
participant. These shares shall be credited to the participant's account.
Certificates shall be held by the ESPP Administrator as nominee for participants
solely as a matter of convenience. A participant shall have all ownership rights
as to the shares credited to his or her account, and neither the ESPP
Administrator nor the Company shall have any ownership or other rights of any
kind with respect to any such certificates or the shares represented thereby.
 
     Restrictions on Transfer.  An employee's rights under the Employee Stock
Purchase Plan may not be transferred other than by will or the laws of descent
and distribution. Any option granted under the Employee Stock Purchase Plan to
an employee may be exercised, during the employee's lifetime, only by the
employee.
 
     Termination of Employee's Rights.  An employee's rights under the Employee
Stock Purchase Plan will terminate when he ceases to be an employee because of
retirement, voluntary or involuntary termination, resignation, lay-off,
discharge, death, change of status or for any other reason, except that if an
employee is on a leave of absence from work during the last three months of any
purchase period, he will be deemed to be a participant in the Employee Stock
Purchase Plan on the last day of that purchase period. A withdrawal notice will
be considered as having been received from the employee on the day his
employment ceases, and all payroll deductions not used to purchase stock will be
refunded. If an employee's payroll deductions are interrupted by any legal
process, a withdrawal notice will be considered as having been received from the
employee an the day the interruption occurs.
 
TERMINATION AND AMENDMENT
 
     The Employee Stock Purchase Plan has no pre-established expiration date and
may be terminated at any time by the Compensation Committee, but such
termination will not affect options then outstanding. The Employee Stock
Purchase Plan will terminate in any case when all or substantially all of the
unissued shares of stock reserved for the purposes of the Employee Stock
Purchase Plan have been purchased. If at any time shares of stock reserved for
the Employee Stock Purchase Plan remain available for purchase but not in
sufficient number to satisfy all then unfilled purchase requirements, the
available shares will be apportioned among participants in proportion to their
options and the Employee Stock Purchase Plan will terminate. Upon termination,
all payroll deductions not used to purchase stock will be refunded. The
Compensation Committee may from time to time amend the Employee Stock Purchase
Plan provided that, without the approval of the stockholders, no amendment may
(i) increase the number of shares that may be issued or change the class of
employees eligible to receive options under the Employee Stock Purchase Plan or
(ii) cause Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), to become inapplicable to the Employee Stock Purchase Plan.
 
FEDERAL INCOME TAX EFFECTS
 
     The Employee Stock Purchase Plan is intended to qualify for the favorable
federal income tax consequences of Code Section 423. Neither the grant nor the
exercise of options granted under the Employee Stock Purchase Plan will have a
tax impact on the participant or the Company. A participant receives a tax basis
in the purchased stock equal to his own contributions. If a participant disposes
of the stock acquired upon
 
                                       18
<PAGE>   22
 
the exercise of his options after at least two years from the date of grant and
one year from the date of exercise (the "required holding period"), then the
participant will recognize as ordinary income the amount by which the lesser of
(i) the fair market value of the stock at the time of disposition, or (ii) the
fair market value of the stock at the date of grant (i.e., at the beginning of
the purchase period) exceeds the participant's tax basis in such stock. Any gain
in addition to this amount will be treated as a capital gain. If a participant
holds stock at the time of his death, the required holding period will
automatically be deemed to have been satisfied and ordinary income must be
realized by the participant in the amount by which the lesser of (i) the fair
market value of the stock at the time of death, or (ii) the fair market value of
the stock at the date of grant (i.e., at the beginning of the purchase period)
exceeds the participant's tax basis in such stock. The Company will not be
entitled to a deduction if the holding period requirements are satisfied.
 
     If a participant disposes of stock before the expiration of the required
holding period, then the participant must recognize as ordinary income the
excess of the fair market value of the stock on the date of exercise of the
option over the participant's tax basis in such stock. Any additional gain will
be treated as long-term or short-term capital gain or loss, as the case may be.
The Company will be allowed a deduction equal to the amount of ordinary income
recognized by the participant (subject to the provisions of Section 162(m) of
the Code).
 
     At the time the option is exercised, in whole or in part, or at the time
some or all of the Common Stock issued under the Employee Stock Purchase Plan is
disposed of, the participant must make adequate provision for the Company's
federal, state or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of such stock. At any time, the
Company may, but will not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the participant.
 
RESTRICTIONS ON RESALE
 
     If an employee is not an "affiliate" of the Company, he may resell the
Common Stock acquired under the Employee Stock Purchase Plan without compliance
with the requirements of Rule 144 of the Exchange Act ("Rule 144"). Otherwise,
resales of Common Stock acquired under the Employee Stock Purchase Plan may be
sold only in compliance with all of the provisions of Rule 144, other than the
one-year holding period requirement, or pursuant to a separate registration for
the sale of such shares. In general, under Rule 144, an "affiliate" (which term
includes executive officers and directors of the Company and persons whose
shares are aggregated with such affiliate) is entitled to sell within any
three-month period a number of shares (including shares received other than
pursuant to the Employee Stock Purchase Plan) that does not exceed the greater
of one percent of the then-outstanding shares of the Company's Common Stock or
the average weekly trading volume in the Nasdaq National Market during the four
calendar weeks preceding the sale.
 
BENEFITS TO NAMED EXECUTIVE OFFICERS AND OTHERS
 
     Directors who are not employees are not entitled to participate in the
Employee Stock Purchase Plan. Participation in the Employee Stock Purchase Plan
is entirely voluntary. Therefore, it is not presently possible to determine the
benefits or amounts that will be received pursuant to the Employee Stock
Purchase Plan by the following persons: (i) the Named Executive Officers, (ii)
all current executive officers as a group, or (iii) all employees, including all
current officers who are not executive officers, as a group.
 
VOTE REQUIRED
 
     The affirmative vote of the holders of a majority of the shares present or
represented by proxy and entitled to vote at the Annual Meeting on this proposal
will constitute approval of the Employee Stock Purchase Plan.
 
     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE PROPOSAL TO
APPROVE THE MEDIRISK, INC. 1998 EMPLOYEE STOCK PURCHASE PLAN.
 
                                       19

                                   PROPOSAL 3
                         APPROVAL OF THE MEDIRISK, INC.
                         1998 LONG-TERM INCENTIVE PLAN
 
     The Company currently maintains the Medirisk, Inc. 1996 Stock Incentive
Plan, under which stock options, stock purchase rights and restricted stock may
be awarded to employees, officers, consultants and directors of the Company.
There are currently 11,080 shares remaining available for awards under the 1996
Incentive Plan. On March 11, 1998, the Board of Directors adopted the Medirisk,
Inc. 1998 Long-Term Incentive Plan (the "Long-Term Incentive Plan"), subject to
stockholder approval, at the Annual Meeting. If the stockholders approve the
Incentive Plan, the Company will grant awards for the remaining shares available
under the 1996 Incentive Plan. The Company has reserved 500,000 shares of its
Common Stock for issuance in connection with options and awards under the
Long-Term Incentive Plan. If approved by the stockholders at the Annual Meeting,
the Long-Term Incentive Plan will be effective as of its adoption by the
stockholders.
 
     A summary of the Long-Term Incentive Plan is set forth below. The summary
is qualified in its entirety by reference to the full text of the Long-Term
Incentive Plan attached to this Proxy Statement as Exhibit "B."
 
GENERAL
 
     The purpose of the Long-Term Incentive Plan is to promote the success, and
enhance the value, of the Company by linking the personal interests of
employees, officers, consultants and directors to those of the stockholders, and
by providing such persons with an incentive for outstanding performance. As of
June 10, 1998, there were approximately 250 persons eligible to participate in
the Long-Term Incentive Plan.
 
     The Long-Term Incentive Plan authorizes the granting of awards ("Awards")
to employees, officers, consultants and directors of the Company or its
affiliated companies in the following forms: (i) options to purchase shares of
Common Stock ("Options"), which may be incentive stock options or nonqualified
stock options, (ii) stock appreciation rights ("SARs"); (iii) performance units
("Performance Units"); (iv) restricted stock ("Restricted Stock"); (v) dividend
equivalents ("Dividend Equivalents"); and (vi) other stock-based awards.
 
     Pursuant to Code Section 162(m), the Company may not deduct compensation in
excess of $1 million paid to the Chief Executive Officer and the four next most
highly compensated executive officers of the Company. The Long-Term Incentive
Plan is designed to comply with Code Section 162(m) so that the grant of Options
and SARs under the plan, and other Awards, such as Performance Units, that are
conditioned on the performance goals described in the plan, will be excluded
from the calculation of annual compensation for purposes of Code Section 162(m)
and will be fully deductible by the Company.
 
     Subject to adjustment as provided in the Long-Term Incentive Plan, the
aggregate number of shares of Common Stock reserved and available for Awards or
which may be used to provide a basis of measurement for or to determine the
value of an Award (such as with a SAR or Performance Unit) is 500,000, of which
no more than 20% may be granted in the form of restricted stock awards. The
maximum number of shares of Common Stock with respect to one or more Options
and/or SARs that may be granted during any one calendar year under the Long-Term
Incentive Plan to any one participant is 100,000. The maximum fair market value
(measured as of the date of grant) of any Awards other than Options and SARs
that may be received by a participant (less any consideration paid by the
participant for such Award) during any one calendar year under the Incentive
Plan is $1,000,000.00.
 
ADMINISTRATION
 
     The Long-Term Incentive Plan will be administered by the Compensation
Committee of the Board of Directors of the Company. The Compensation Committee
has the power, authority and discretion to designate participants; determine the
type or types of Awards to be granted to each participant and the terms and
conditions thereof; establish, adopt or revise any rules and regulations as it
may deem necessary or advisable to administer the Long-Term Incentive Plan; and
make all other decisions and determinations that may be
 
                                       20
<PAGE>   24
 
required under, or as the Compensation Committee deems necessary or advisable to
administer, the Long-Term Incentive Plan.
 
AWARDS
 
     Stock Options.  The Compensation Committee is authorized to grant Options,
which may be incentive stock options ("ISOs") or nonqualified stock options
("NQSOs"), to participants. All Options will be evidenced by a written Award
Agreement between the Company and the participant, which will include such
provisions as may be specified by the Compensation Committee. The terms of any
ISO must meet the requirements of Code Section 422.
 
     Stock Appreciation Rights.  The Compensation Committee may grant SARs to
participants. Upon the exercise of a SAR, the participant has the right to
receive the excess, if any, of: the fair market value of one share of Common
Stock on the date of exercise, over the grant price of the SAR as determined by
the Compensation Committee, which will not be less than the fair market value of
one share of Common Stock on the date of grant in the case of any SAR related to
an ISO. All awards of SARs will be evidenced by an Award Agreement, reflecting
the terms, methods of exercise, methods of settlement, form of consideration
payable in settlement, and any other terms and conditions of the SAR, as
determined by the Compensation Committee at the time of grant.
 
     Performance Units.  The Compensation Committee may grant Performance Units
to participants on such terms and conditions as may be selected by the
Compensation Committee. The Compensation Committee will have the complete
discretion to determine the number of Performance Units granted to each
participant and to set performance goals and other terms or conditions to
payment of the Performance Units in its discretion which, depending on the
extent to which they are met, will determine the number and value of Performance
Units that will be paid to the participant.
 
     Restricted Stock Awards.  The Compensation Committee may make awards of
Restricted Stock to participants, which will be subject to such restrictions on
transferability and other restrictions as the Compensation Committee may impose
(including, without limitation, limitations on the right to vote Restricted
Stock or the right to receive dividends, if any, on the Restricted Stock).
 
     Dividend Equivalents.  The Compensation Committee is authorized to grant
Dividend Equivalents to participants subject to such terms and conditions as may
be selected by the Compensation Committee. Dividend Equivalents entitle the
participant to receive payments equal to dividends with respect to all or a
portion of the number of shares of Common Stock subject to an Award, as
determined by the Compensation Committee. The Compensation Committee may provide
that Dividend Equivalents be paid or distributed when accrued or be deemed to
have been reinvested in additional shares of Common Stock, or otherwise
reinvested.
 
     Other Stock-Based Awards.  The Compensation Committee may, subject to
limitations under applicable law, grant to participants such other Awards that
are payable in, valued in whole or in part by reference to, or otherwise based
on or related to shares of Common Stock, as deemed by the Compensation Committee
to be consistent with the purposes of the Long-Term Incentive Plan, including
without limitation shares of Common Stock awarded purely as a "bonus" and not
subject to any restrictions or conditions, convertible or exchangeable debt
securities, other rights convertible or exchangeable into shares of Common
Stock, and Awards valued by reference to book value of shares of Common Stock or
the value of securities of or the performance of specified affiliated companies
of the Company. The Compensation Committee will determine the terms and
conditions of any such Awards.
 
     Performance Goals.  The Compensation Committee may determine that any Award
will be determined solely on the basis of (a) the achievement by the Company or
a parent or subsidiary of a specified target return, or target growth in return,
on equity or on assets, (b) the Company's or a parent's or subsidiary's stock
price, (c) the achievement by an individual or a business unit of the Company or
a parent or subsidiary of a specified target, or target growth in, revenues, net
income or earnings per share, or (d) any combination of the goals set forth in
(a) through (c) above. If an Award is made on such basis, the Compensation
Committee
 
                                       21
<PAGE>   25
 
must establish goals prior to the beginning of the period for which such
performance goal relates (or such later date as may be permitted under Code
Section 162(m)), and the Compensation Committee may for any reason reduce (but
not increase) any Award, notwithstanding the achievement of a specified goal.
Any payment of an Award granted with performance goals will be conditioned on
the written certification of the Compensation Committee in each case that the
performance goals and any other material conditions were satisfied.
 
     Limitations on Transfer; Beneficiaries.  No unexercised or restricted Award
will be assignable or transferable by a participant other than by will or the
laws of descent and distribution or, except in the case of an ISO, pursuant to a
qualifying domestic relations order; provided, however, that the Compensation
Committee may (but need not) permit other transfers where the Compensation
Committee concludes that such transferability (i) does not result in accelerated
taxation, (ii) does not cause any Option intended to be an ISO to fail to be
described in Code Section 422(b), and (iii) is otherwise appropriate and
desirable, taking into account any factors deemed relevant, including without
limitation, any state or federal tax or securities laws or regulations
applicable to transferable Awards. A participant may, in the manner determined
by the Compensation Committee, designate a beneficiary to exercise the rights of
the participant and to receive any distribution with respect to any Award upon
the participant's death.
 
     Acceleration Upon Certain Events.  Upon the participant's death or
disability, all outstanding Options, SARs, and other Awards in the nature of
rights that may be exercised will become fully exercisable and all restrictions
on outstanding Awards will lapse. Any Options or SARs will thereafter continue
or lapse in accordance with the other provisions of the Long-Term Incentive Plan
and the Award Agreement. In the event of a Change in Control of the Company (as
defined in the Long-Term Incentive Plan), all outstanding Options, SARs, and
other Awards in the nature of rights that may be exercised will become fully
vested and all restrictions on all outstanding Awards will lapse. In the event
of the occurrence of any circumstance, transaction or event not constituting a
Change in Control but which the Board of Directors deems to be, or to be
reasonably likely to lead to, an effective change in control of the Company, the
Compensation Committee or the Board may in its sole discretion declare all
outstanding Options, SARs, and other Awards in the nature of rights that may be
exercised to become fully vested, and/or all restrictions on all outstanding
Awards to lapse, in each case as of such date as the Compensation Committee or
the Board may, in its sole discretion, declare, which may be on or before the
consummation of such transaction or event.
 
TERMINATION AND AMENDMENT
 
     With the approval of the Board, at any time and from time to time, the
Compensation Committee may terminate, amend or modify the Long-Term Incentive
Plan without shareholder approval; provided, however, that the Compensation
Committee may condition any amendment on the approval of shareholders of the
Company if such approval is necessary or deemed advisable with respect to tax,
securities or other applicable laws, policies or regulations. No termination,
amendment, or modification of the Long-Term Incentive Plan may adversely affect
any Award previously granted under the Incentive Plan, without the written
consent of the participant.
 
CERTAIN FEDERAL INCOME TAX EFFECTS
 
     Nonqualified Stock Options.  Under present federal income tax regulations,
there will be no federal income tax consequences to either the Company or the
participant upon the grant of a nondiscounted NQSO. However, the participant
will realize ordinary income on the exercise of the NQSO in an amount equal to
the excess of the fair market value of the Common Stock acquired upon the
exercise of such option over the exercise price, and the Company will receive a
corresponding deduction (subject to the provisions of Section 162(m) of the
Code). A subsequent sale or exchange of such shares will result in gain or loss
measured by the difference between (i) the exercise price, increased by any
compensation reported upon the participant's exercise of the option, and (ii)
the amount realized on such sale or exchange. Such gain or loss will be capital
in nature if the shares were held as a capital asset and will be long-term if
such shares were held for the applicable long-term capital gain holding period.
 
                                       22
<PAGE>   26
 
     Incentive Stock Options.  Under present federal income tax regulations,
there will be no federal income tax consequences to either the Company or the
participant upon the grant of an ISO or the exercise thereof by the participant.
If the participant holds the shares of Common Stock for the greater of two years
after the date the Option was granted or one year after the acquisition of such
shares of Common Stock (the "required holding period"), the difference between
the aggregate exercise price and the amount realized upon disposition of the
shares of Common Stock will constitute a capital gain or loss, and the Company
will not be entitled to a federal income tax deduction. If the shares of Common
Stock are disposed of in a sale, exchange or other "disqualifying disposition"
during the required holding period, the participant will realize taxable
ordinary income in an amount equal to the excess (if any) of the fair market
value of the Common Stock purchased at the time of exercise (or, if less, the
amount realized on the disposition of the shares) over the aggregate exercise
price, and the Company will be entitled to a federal income tax deduction equal
to such amount (subject to the provisions of Section 162(m) of the Code). Upon
exercise of an ISO, the participant may be subject to alternative minimum tax on
certain items of tax preference. If an ISO is exercised at a time when it no
longer qualifies as an incentive stock option, the option will be treated as an
NQSO.
 
     SARs.  Under present federal income tax regulations, a participant
receiving a nondiscounted SAR will not recognize income, and the Company will
not be allowed a tax deduction, at the time the Award is granted. When a
participant exercises the SAR, the amount of cash and the fair market value of
any shares of Common Stock received will be ordinary income to the participant
and will be allowed as a deduction for federal income tax purposes to the
Company.
 
     Performance Units.  Under present federal income tax regulations, a
participant receiving Performance Units will not recognize income and the
Company will not be allowed a tax deduction at the time the Award is granted.
When a participant receives payment of Performance Units, the amount of cash and
the fair market value of any shares of Common Stock received will be ordinary
income to the participant, and the Company will be entitled to a corresponding
tax deduction at that time.
 
     Restricted Stock.  Under present federal income tax regulations, and unless
the participant makes an election to accelerate recognition of the income to the
date of grant, a participant receiving a Restricted Stock Award will not
recognize income, and the Company will not be allowed a tax deduction, at the
time the Award is granted. When the restrictions lapse, the participant will
recognize ordinary income equal to the fair market value of the Common Stock,
and the Company will be entitled to a corresponding tax deduction at that time.
 
BENEFITS TO NAMED EXECUTIVE OFFICERS AND OTHERS
 
     As of June 10, 1998, no awards had been granted or approved for grant under
the Long-Term Incentive Plan. Any future awards will be made at the discretion
of the Committee. Therefore, it is not presently possible to determine with
respect to (i) the Named Executive Officers, (ii) all current executive
officers, as a group, (iii) all current directors who are not executive
officers, as a group, or (iv) all employees, including all current officers who
are not executive officers, as a group, either the benefits or amounts that will
be received by such persons or groups pursuant to the Long-Term Incentive Plan
or the benefits or amounts that would have been received by such persons or
groups under the Long-Term Incentive Plan if it had been in effect during the
last fiscal year.
 
ADDITIONAL INFORMATION
 
     The closing price of the Common Stock, as reported by the Nasdaq National
Market on June 10, 1998, was $19.375.

                                   PROPOSAL 4
APPROVAL, FOR PURPOSES OF THE LISTING REQUIREMENTS OF THE NASDAQ STOCK MARKET'S
NATIONAL MARKET, OF THE ISSUANCE OF COMMON STOCK OR SERIES 1998-A PREFERRED
STOCK BY THE COMPANY TO THE FORMER SHAREHOLDERS OF HEALTHDEMOGRAPHICS, A
CORPORATION RECENTLY ACQUIRED BY THE COMPANY, TO THE EXTENT SUCH ISSUANCE COULD
RESULT IN THE COMPANY ISSUING MORE THAN TWENTY PERCENT (20%) OF THE ISSUED AND
OUTSTANDING COMMON STOCK OF THE COMPANY AS OF MARCH 31, 1998 IN CONNECTION WITH
THE ACQUISITION OF HEALTHDEMOGRAPHICS (THE "HEALTHDEMOGRAPHICS ISSUANCE").
 
GENERAL
 
     On March 26, 1998 the Company, Healthdemographics, Inc., a Delaware
corporation and a wholly-owned subsidiary of the Company ("Merger Sub"),
Healthdemographics, a California corporation ("Healthdemographics"), and certain
shareholders of Healthdemographics entered into an Acquisition Agreement and
Plan of Merger (the "Merger Agreement"). Under the Merger Agreement, the Company
acquired Healthdemographics through the merger (the "Merger") of
Healthdemographics with and into Merger Sub, with Merger Sub surviving as a
wholly-owned subsidiary of the Company. In consideration for acquiring all of
the issued and outstanding stock of Healthdemographics in the Merger, the
Company (i) issued 171,315 shares of its $0.001 par value Common Stock, (ii)
paid approximately $2.7 million in cash, (iii) assumed Healthdemographics net
liabilities, and (iv) agreed to pay certain additional consideration (the
"Contingent Consideration") to the former shareholders of Healthdemographics, if
Healthdemographics achieves certain operating income objectives. A copy of the
Merger Agreement is attached to this Proxy Statement as Exhibit "C".
 
BACKGROUND OF THE MERGER
 
     Beginning in September 1997, the Company began preliminary research on
Healthdemographics. Specifically, the Company studied the scope and strength of
the market for Healthdemographics' products and the ability of
Healthdemographics to compete with other companies providing similar
decision-support software.
 
     On November 21, 1997, the Company sent a letter to P. Timothy Garton,
President of Healthdemographics, to schedule a meeting between the Company and
Healthdemographics. Representatives of the Company and Healthdemographics met in
December 1997, and following exchanges of additional information, the Company
and Healthdemographics entered into a Confidentiality Agreement dated December
31, 1997.
 
     In February 1998 representatives of the Company traveled to San Diego to
perform due diligence on Healthdemographics. In February and March 1998,
representatives of the Company continued to conduct due diligence and began
preliminary negotiations of acquisition terms and documents with representatives
of Healthdemographics. On March 11, 1998, the Board of Directors of the Company
approved the acquisition subject to the resolution of a number of issues,
including final transaction structure.
 
     In late March 1998, representatives of Healthdemographics met with
representatives of the Company to resolve remaining issues, including the
initial consideration and earn-out consideration to be paid, final transaction
structure, employment issues and noncompetition agreements. The parties resolved
these issues, and acquisition documents were executed on March 26, 1998.
 
     On March 31, 1998, after the satisfaction of various closing conditions and
the filing of a Certificate of Merger with the Secretaries of State of
California and Delaware, the Merger was completed. Following the close of the
Nasdaq Stock Market on March 31, 1998, the Company issued a press release to
announce the closing of the Merger.

REASONS FOR THE MERGER
 
     In reaching its decision to approve the Merger Agreement and the
transactions contemplated thereby, the Board of Directors of the Company
consulted with management of the Company and various advisors and independently
considered a number of factors. In view of the variety of factors considered in
its evaluation of the Merger, the Board of Directors did not find it practicable
to, and did not, quantify or otherwise attempt to assign relative weights to the
specific factors considered in reaching its determination. Factors considered
include the following:
 
          (i) The products offered by Healthdemographics will allow the Company
     to expand the Company's market performance products and customer base.
 
          (ii) By forecasting demand for healthcare services,
     Healthdemographics' products will allow the Company's customers to make
     more informed business decisions regarding strategic planning and marketing
     planning and analysis.
 
          (iii) The opportunities for economies of scale and operating
     efficiencies that should result from the Merger including the integration
     of information systems and support functions.
 
          (iv) The belief that the combination of Healthdemographics products
     and management team with the financial resources and experience of the
     Company will provide a significant opportunity for the expansion of
     Healthdemographics, products and customer base.
 
          (v) On the basis of the relative earnings of both companies and the
     exchange ratio, the Company believed the Merger would be accretive to its
     current stockholders in the near term, and would be more so in the future
     if certain synergies are achieved.
 
          (vi) By including in the Merger Agreement incentive for future growth
     through the payment of the Contingent Consideration, the Company has
     provided the Healthdemographics' management team incentive to continue to
     expand Healthdemographics' operating income.
 
CONSIDERATION ISSUED IN THE MERGER
 
     At the effective time of the Merger, each share of Healthdemographics
capital stock was converted into (i) the right to receive its pro rata portion
of the aggregate merger consideration in cash and stock, and (ii) the right to
receive the Contingent Consideration. The aggregate initial consideration issued
and delivered to shareholders of Healthdemographics was 171,315 shares of Common
Stock and approximately $2.7 million in cash.
 
     The payment of the Contingent Consideration is contingent upon
Healthdemographics achieving certain quarterly operating income targets. The
parties negotiated these operating income targets at arm's length prior to
entering into the Merger Agreement. The Contingent Consideration payable by the
Company is a multiple of Healthdemographics' operating income over predetermined
operating income targets. The predetermined targets were established based on
the Company's projections concerning Healthdemographics' business and growth.
The multiple to be applied to operating income in excess of these targets varies
according to the amount, if any, by which actual operating income exceeds the
predetermined targets. Payments of Contingent Consideration will be made 50% in
cash and 50% in either Common Stock or Series 1998-A Preferred Stock. The
Company's obligation to make the Contingent Consideration payments extends
through the year 2000. There is no minimum Contingent Consideration guaranteed,
and the former shareholders of Healthdemographics could receive no additional
payments. In addition, there is no upper limit on the Contingent Consideration.
 
     As noted above, the Contingent Consideration will be payable in a
combination of cash and Common Stock or Series 1998-A Preferred Stock. The
Series 1998-A Preferred Stock will be issuable only if, at the time a payment of
Contingent Consideration is due, the market price for Common Stock is less than
$22.6094 per share. If the Series 1998-A Preferred Stock is issued, it will be
issued at its liquidation preference of $10,000 per share.

DESCRIPTION OF SERIES 1998-A PREFERRED STOCK
 
     To satisfy the Company's obligation to make payments of Contingent
Consideration in stock of the Company in order to preserve the tax treatment of
the Merger, the Company's Board of Directors created a new series of Preferred
Stock of the Company, par value $0.001, designated as the Series 1998-A
Preferred Stock. The Board of Directors designated 5,000 of the previously
undesignated shares of Preferred Stock as Series 1998-A Preferred Stock. The
principal features of the Series 1998-A Preferred Stock, which will apply if it
is issued and until its conversion, are summarized below. The following
description of the Series 1998-A Preferred Stock is only a summary of certain
provisions and is qualified in its entirety by reference to the copy of the
Certificate of Designation for the Series 1998-A Preferred Stock attached as
Exhibit "D" to this Proxy Statement (the "Certificate of Designation").
 
     Dividends:  The holders of Series 1998-A Preferred Stock are entitled to
receive cash dividends payable before any dividends are paid to holders of
Common Stock or any other securities ranking junior to the Series 1998-A
Preferred Stock at the rate of 5% per annum of the initial liquidation
preference per share of the Series 1998-A Preferred Stock ($10,000). Dividends
on the Series 1998-A Preferred Stock accrue from and after the date shares are
issued and are payable annually on December 31 of each year. The Company may, in
the discretion of the Board of Directors, declare and pay dividends or
distributions, or make provision for the payment thereof, on Common Stock or any
security ranking junior to the Series 1998-A Preferred Stock, but only if all
accrued dividends on the Series 1998-A Preferred Stock have been paid in full
prior to the date of any such declaration, payment or provision.
 
     Liquidation Rights:  Upon any liquidation, dissolution and winding up of
the Company, holders of Series 1998-A Preferred Stock will be entitled to
receive, from the assets of the Company available for distribution to
stockholders of the Company, an amount equal to $10,000 per share plus any
accrued and unpaid dividends on the Series 1998-A Preferred Stock (the
"Liquidation Preference") before any distribution is made to holders of Common
Stock or any other class of stock ranking junior upon liquidation, dissolution
and winding up to the Series 1998-A Preferred Stock.
 
     Voting Rights:  Each share of Series 1998-A Preferred Stock is entitled to
a number of votes equal to the number of shares of Common Stock into which such
share of Series 1998-A Preferred Stock is then convertible. Except as otherwise
provided by the Delaware General Corporation law, the holders of Series 1998-A
Preferred Stock will vote together with the holders of Common Stock as a single
class on all matters on which the holders of Common Stock are entitled to vote.
 
     Redemption:  Beginning on the fifth anniversary of any issue date of shares
of Series 1998-A Preferred Stock, the Company may, but is not required to,
redeem all of the shares of Series 1998-A Preferred Stock that were issued on
such issue date and that remain outstanding. Effective as of the twentieth
anniversary of each issue date of shares of Series 1998-A Preferred Stock, the
Company is required to redeem all of the shares of Series 1998-A Preferred Stock
that were issued on such issue date and that remain outstanding. Upon any
redemption of the Series 1998-A Preferred Stock, the Company will pay in cash
the Liquidation Preference in effect on the date established for redemption, and
dividends shall cease to accrue on that date. The Company will not establish any
retirement or sinking fund for the redemption of the Series 1998-A Preferred
Stock.
 
     Conversion:  Each share of Series 1998-A Preferred Stock is subject to
automatic conversion into Common Stock if, at any time, the Market Value (as
defined in the Certificate of Designation) of Common Stock equals or exceeds
$22.6094 (the "Conversion Price"). In such event, each share of Series 1998-A
Preferred Stock will, automatically and without action on the part of the holder
or the Company, be converted into a number of shares of Common Stock that
results from dividing the Liquidation Preference in effect at the time by the
Conversion Price. To protect against dilution, the Conversion Price is subject
to adjustment if the Company effects a subdivision or combination of Common
Stock (whether by stock split, stock dividend or otherwise). The Conversion
Price and securities issuable upon conversion are also subject to adjustment if
the company (i) conducts a capital reorganization of Common Stock, (ii) engages
in a merger, consolidation or statutory share exchange in which the stockholders
of the Company prior to such transaction own less than
 
                                       26
<PAGE>   30
 
a majority of the voting stock of the resulting, surviving or exchanging
corporation, or (iii) sells all or substantially all of its properties or assets
or capital stock.
 
     Rank:  The Series 1998-A Preferred Stock ranks prior to Common Stock with
respect to the payment of dividends and distributions of assets upon the
dissolution, liquidation and winding up of the Company. The Board of Directors
may at any time and from time to time include additional shares in the
designation of the Series 1998-A Preferred Stock, designate one or more series
or classes of preferred stock with liquidation preferences, voting rights,
dividend rights and other rights and privileges senior to the Series 1998-A
Preferred Stock without the vote or consent of, or notice to, the holders of
Series 1998-A Preferred Stock.
 
FRACTIONAL SHARES
 
     No certificates representing fractional shares of Common Stock were issued
as a result of the Merger. Any fractional interest to which a former shareholder
of Healthdemographics was entitled was satisfied through the payment of cash in
an amount equal to such fractional part of a share of Common Stock multiplied by
$22.6094.
 
EFFECT OF THE MERGER ON THE COMPANY'S SHAREHOLDERS
 
     Consummation of the Merger and the issuance of Common Stock in connection
with the Merger did not result in any change in the rights of the holders of
Common Stock under the provisions of the General Corporation Law of the State of
Delaware or the Company's Certificate of Incorporation or Bylaws. Although the
rights of the Common Stock were not modified as a result of the Merger, the
Series 1998-A Preferred Stock that may be issued as Additional Consideration has
rights and preferences superior to the rights of Common Stock.
 
CERTAIN FEDERAL TAX CONSEQUENCES
 
     The following discussion is a summary of certain of the federal income tax
consequences of the Merger This discussion is not a complete description of all
the consequences of the Merger. Each Healthdemographics shareholder's individual
circumstances may affect the tax consequences of the Merger to him or her. For
example, the discussion does not address the effect of the Merger to certain
classes of taxpayers, including, without limitation, shareholders of
Healthdemographics who held their stock other than as a capital asset, who
received their stock upon the exercise of employee stock options or otherwise as
compensation, and shareholders who were foreign persons, insurance companies,
financial institutions or securities dealers. In addition, no information is
provided herein with respect to the tax consequences of the Merger under
applicable foreign, state or local laws. Accordingly, each shareholder of
Healthdemographics is urged to consult his or her own tax advisor as to the
specific federal income tax consequences to such shareholder, based on his or
her own particular status and circumstances, and also as to any state, local,
foreign or other tax consequences arising out of the Merger to him or her.
 
     The discussion is based on the Internal Revenue Code of 1986, as amended
(the "Code"), regulations and rulings as now in effect or proposed thereunder,
current administrative rulings and practice, and judicial precedent, all of
which are subject to change. Any such change, which may or may not be
retroactive, could alter the tax consequences discussed herein. Furthermore,
there can be no assurance that the Internal Revenue Service will not take a view
contrary to those expressed herein. In the discussion below, all Section
references are to the Code, and the term Company Stock refers to shares of stock
of the Company issued in the Merger as consideration, whether at of the time the
Merger became effective, or later as Contingent Consideration.
 
     Based on presently applicable federal income tax law, the Merger had the
following federal income tax consequences:
 
          (i) The Merger qualified as a reorganization within the meaning of
     Section 368(a) of the Code and each of Company, Healthdemographics and
     Merger Sub was a party to the reorganization within the meaning of Section
     368(b) of the Code.
 
                                       27
<PAGE>   31
 
          (ii) No gain or loss was recognized by Company, Healthdemographics or
     Merger Sub as a consequence of the Merger.
 
          (iii) No loss was or will be recognized by shareholders of
     Healthdemographics upon the exchange of Healthdemographics shares of stock
     for shares of Company Stock and any cash consideration received in the
     Merger. Subject to the opinion set forth in paragraph (iv) below, gain, if
     any, will be recognized by each shareholder of Healthdemographics in an
     amount equal to the excess of the fair market value of Company Stock
     received plus any cash consideration received over such shareholder's tax
     basis in the Healthdemographics shares exchanged therefor, but not in
     excess of the total cash received. The general rule is that any such gain
     will be treated as capital gain but if the exchange has the effect of a
     distribution of a dividend, then the amount of gain recognized, that is not
     in excess of the shareholder's ratable share of the undistributed earnings
     and profits of Healthdemographics, will be treated as a dividend, rather
     than capital gain. The determination of whether the exchange has the effect
     of the distribution of a dividend will be made on a shareholder by
     shareholder basis. The exchange will not have the effect of the
     distribution of a dividend, provided that one of the safe-harbors of
     Section 302(b) of the Code is met or the distribution otherwise is
     considered not to have the effect of a dividend. Most shareholders of
     Healthdemographics likely will meet the "substantially disproportionate"
     safe-harbor of Section 302(b)(2) of the Code, and thus have their gain
     treated as capital gain. The substantially disproportionate test will be
     met if after the transaction Healthdemographics shareholder will own less
     than fifty percent (50%) of all Company Stock and if his or her percentage
     ownership of Company Stock after the transaction is less than eighty
     percent (80%) of what his or her percentage ownership of Company Stock
     would have been if Company Stock instead of cash consideration had been
     received by the shareholder in connection with the Merger, in each case
     determined with application of Section 318 of the Code attributing stock
     ownership among family members and related entities.
 
          (iv) To the extent any portion of the Contingent Consideration is
     treated as interest, such amount will be treated as taxable ordinary income
     to shareholders of Healthdemographics.
 
          (v) A shareholder of Healthdemographics who receives cash in the
     Merger in lieu of a fractional share interest in Healthdemographics Stock,
     or because of the exercise of the right to dissent, would be treated as
     having received cash in redemption of the Company Stock that would have
     been received by such shareholder had Company Stock been issued instead of
     cash, subject to the provisions of Section 302 of the Code. The receipt of
     cash by such shareholder generally should result in capital gain or loss
     equal to the difference between the amount of cash received and the
     shareholder's basis in the shares of Healthdemographics stock, or
     fractional interest in a share of Healthdemographics stock.
 
          (vii) Except to the extent any Company Stock is treated as interest,
     the holding period of the Company Stock received by a shareholder of
     Healthdemographics includes the holding period of the Healthdemographics
     stock surrendered in exchange therefor, provided the Healthdemographics
     stock was held as a capital asset on the date of the exchange.
 
     Although not entirely clear, the basis of the Company Stock received by a
shareholder of Healthdemographics in the Merger (other than Company Stock
treated as interest) should, in the aggregate, be the same as the aggregate
basis of the Healthdemographics Stock surrendered in exchange therefor (less the
basis allocated to any fractional share of Company Stock settled by cash
payment), decreased by any cash received, and increased by the amount treated as
a dividend, the amount of the gain recognized by such shareholder with respect
to the Merger, and any portion of the Contingent Consideration treated as
interest. Until the final payment of the Company Common or Preferred Stock
issued as Contingent Consideration has been made, such basis should be
determined as though the maximum number of shares of Company Stock that the
shareholder of Healthdemographics reasonably estimates she or he will receive
had been issued (not including any shares of Company Stock treated as interest)
under the Agreement to the shareholder as Contingent Consideration.
 
     The Merger Agreement provides that notwithstanding any provisions of the
Merger Agreement, the aggregate consideration issued in the Merger will consist
not less than fifty percent (50%) of Company Stock. The discussion above assumes
that such fifty percent (50%) computation is based on the value of the
                                       28
<PAGE>   32
 
Company Stock at the time of its issuance as consideration in the merger. The
tax consequences above may not obtain if this assumption is not valid.
 
NONCOMPETITION AGREEMENTS AND EMPLOYMENT AGREEMENTS
 
     The Company entered into Noncompetition Agreements with P. Timothy Garton
and Michael D. Chermak. Pursuant to the terms of these Noncompetition
Agreements, Messrs. Chermak and Garton agreed for a period of five years
following the execution date of the Merger Agreement (i) not to compete with the
Company in the development, implementation, marketing or sale of software,
databases or other tools relating to the collection, maintenance or utilization
of data concerning the supply of, and demand for, healthcare related products
and services; (ii) not to hire, solicit or attempt to hire or solicit any
employee of the Company on behalf of another company; (iii) enter into or
attempt to enter into any business substantially similar to the business
operated by Healthdemographics; and (iv) not to directly or indirectly divulge
any of the Company's confidential information.
 
     The Company also entered into Employment Agreements with Mr. Chermak (the
"Chermak Agreement") and Mr. Garton (the "Garton Agreement"). The Chermak
Agreement provides that Mr. Chermak will serve as the Vice President and General
Manager of Healthdemographics, Inc. until March 31, 2001. Under the Chermak
Agreement, the Company will pay Mr. Chermak an annual base salary of $125,000 in
accordance with the Company's current payroll practices. Any increase in Mr.
Chermak's salary, as well as the payment of any bonuses and the grant of any
stock options to Mr. Chermak, must be approved by the Board of Directors of the
Company. In addition, Mr. Chermak will be entitled to certain fringe benefits as
part of his employment, including reimbursement for reasonable and necessary
business expenses, four weeks of paid vacation per year and participation in the
Company's standard benefit programs. The Company may terminate Mr. Chermak's
employment at any time prior to March 31, 2001 for cause or upon the disability
of Mr. Chermak. If the Company terminates Mr. Chermak without cause prior to
March 31, 2001, Mr. Chermak shall be entitled to receive his base salary for the
remainder of the term of the agreement payable periodically in accordance with
the Company's payroll procedures.
 
     The Garton Agreement provides that Mr. Garton will serve as the President
of Healthdemographics, Inc. until March 31, 2001. Under the Garton Agreement,
the Company will pay Mr. Garton an annual base salary of $125,000 payable in
accordance with the Company's current payroll practices. Any increase in Mr.
Garton's salary, as well as the payment of any bonuses and the grant of any
stock options to Mr. Garton, must be approved by the Board of Directors of the
Company. In addition, Mr. Garton will be entitled to certain fringe benefits as
part of his employment, including reimbursement for reasonable and necessary
business expenses, four weeks of paid vacation per year and participation in the
Company's standard benefit programs. The Company may terminate Mr. Garton's
employment at any time prior to March 31, 2001 for cause or upon the disability
of Mr. Garton. If the Company terminates Mr. Garton without cause prior to March
31, 2001, Mr. Garton shall be entitled to receive his base salary for the
remainder of the term of the agreement payable periodically in accordance with
the Company's payroll procedures.
 
INTERESTS OF CERTAIN PERSONS IN THE TRANSACTION
 
     At the closing date, there was no material relationship between the Company
and Healthdemographics or any of the Healthdemographics shareholders, or any of
their respective affiliates, officers, directors or associates, except for a
$300,000 working capital loan that the Company made to Healthdemographics during
the acquisition discussions to fund current obligations of Healthdemographics.
This working capital loan was extinguished with a portion of the proceeds of the
Merger.
 
INDEMNIFICATION
 
     P. Timothy Garton and Michael D. Chermak, former shareholders, officers and
directors of Healthdemographics, have agreed jointly and severally to indemnify
and hold the Company and Merger Sub harmless against any losses and expenses,
including reasonable attorney's fees, arising out of (i) the breach of any
representation or warranty of Healthdemographics, and (ii) the nonfulfillment or
breach of any covenant
 
                                       29
<PAGE>   33
 
or agreement of Healthdemographics. In addition, each shareholder of
Healthdemographics has agreed, severally and not jointly, to indemnify and hold
harmless the Company and Merger Sub against any losses and expenses, including
reasonable attorney's fees arising out of (i) the breach of any representation
or warranty made by each shareholder, and (ii) the non-fulfillment of any
covenant or agreement by the former shareholders of Healthdemographics. The
Company and Merger Sub have agreed to indemnify and hold harmless the former
shareholders of Healthdemographics against any losses and expenses, including
reasonable attorney's fees, arising out of (i) the breach of any representation
or warranty of the Company and Merger Sub, and (ii) the non-fulfillment of any
covenant or agreement of the Company and Merger Sub. No initial claim for
indemnification with respect to any alleged misrepresentation or breach of
warranty may be made by any party after October 31, 2002, except that the
Company may bring claims prior to the seventh anniversary of the closing date
for breaches of certain agreed upon representations, warranties and covenants.
In addition, no claim for indemnification with respect to any alleged
misrepresentation or breach of warranty may be brought by the Company until the
aggregate amount of any loss or claim for which indemnification is sought
exceeds $100,000, and then indemnification may be asserted for amounts up to and
in excess of $100,000. No former shareholders of Healthdemographics shall be
required to satisfy an indemnification obligation in excess of 100% of the
aggregate value of the consideration received by such shareholder, and the
Company and Merger Sub shall not be required to satisfy an indemnification
obligation in excess of 100% of the aggregate value of all consideration paid by
the Company to the former shareholders of Healthdemographics. In order to
satisfy the indemnification obligations of the former shareholders of
Healthdemographics, the Company has the right to offset the amount of any
indemnification obligations owed to the Company against the payment of the
Contingent Consideration.
 
REGULATORY APPROVALS
 
     Neither the Company nor Healthdemographics was required to comply with any
material federal or state regulatory requirements in connection with the Merger.
As noted above, the Merger has been already consummated, and this approval is
sought solely in connection with the potential Healthdemographics Issuance in
payment of Contingent Consideration.
 
ACCOUNTING TREATMENT
 
     The Merger was accounted for using the purchase method of accounting. The
Merger resulted in estimated purchased in-process research and development costs
of approximately $5.3 million, estimated acquired products of approximately
$500,000, and estimated excess of cost over net assets acquired of approximately
$1.1 million. The Contingent Consideration paid, if any, will be added to the
excess of cost over net assets acquired and amortized prospectively.
 
VOTE REQUIRED
 
     For companies listed on the Nasdaq Stock Market's National Market, the
National Association of Securities Dealers, Inc. (the "NASD"), requires
shareholder approval if the listed company issues more than 20% of the company's
outstanding shares of common stock and voting power in connection with a
transaction. At the effective time of the Merger, the Company did not issue more
than 20% of its outstanding Common Stock or voting power. However, because the
payment of the Contingent Consideration to the former shareholders of
Healthdemographics may result in the issuance by the Company of more than 20% of
the Company's outstanding Common Stock, the shareholders of the Company are
being asked to approve the issuance by the Company of any additional shares of
Common Stock in excess of 20% of the outstanding Common Stock of the Company as
of March 31, 1998. The affirmative vote of the holders of a majority of the
shares present or represented by proxy and entitled to vote at the Annual
Meeting on this proposal will constitute approval of the Healthdemographics
Issuance.
 
     FOR THE REASONS SET FORTH ABOVE, THE BOARD OF DIRECTORS UNANIMOUSLY
RECOMMENDS A VOTE "FOR" THE PROPOSAL TO APPROVE THE HEALTHDEMOGRAPHICS ISSUANCE.

                                MATERIAL CHANGES
 
     Since December 31, 1997, in addition to the acquisition of
Healthdemographics, the Company has experienced the following material changes:
 
RECENT ACQUISITION
 
     On May 28, 1998, the Company acquired by merger all of the capital stock of
Successful Solutions, Inc., a Georgia corporation ("Successful Solutions"), for
190,000 shares of the Company's $0.001 par value per share common stock (the
"Common Stock") and approximately $2.9 million in cash (the "Acquisition").
Contingent Consideration in stock and cash is payable if Successful Solutions
achieves certain performance objectives. Medirisk expects to record a
nonrecurring charge of approximately $4.0 million in the second quarter of 1998
relating to acquired in-process research and development costs and approximately
$400,000 during 1998 for planned integration costs. The Company will account for
the Acquisition as a purchase transaction. The Acquisition was made pursuant to
an Acquisition Agreement and Plan of Merger dated as of May 28, 1998 by and
among the Company, a newly formed merger subsidiary of the Company, Successful
Solutions and the shareholders of Successful Solutions (the "Acquisition
Agreement").
 
     To finance the cash portion of the purchase price, the Company used
borrowings under its existing resolving credit facility with NationsBank. As a
result of these borrowings, at May 28, 1998 the Company had $9.8 million in
borrowings outstanding under its credit facility.
 
     The Company and Successful Solutions also entered into Employment
Agreements with a senior executive of Successful Solutions. The purchase price
and other terms of the Acquisition were determined as a result of arms' length
negotiations between unrelated parties. At the closing date, there was no
material relationship between the Company and Successful Solutions or any of the
Successful Solutions shareholders, or any of their respective affiliates,
officers, directors or associates.

PUBLIC OFFERING
 
     On June 10, 1998, the Company's Registration Statement on Form S-3 with
respect to an offering by the Company and certain selling stockholders of an
aggregate of 2,500,000 shares of Common Stock (2,250,000 being offered by the
Company and 250,000 by the selling stockholders) was declared effective. On June
16, 1998, the offering was consummated, and the Company received net proceeds of
$41,118,750, $9.8 million of which was used to repay outstanding indebtedness
under the Company's revolving credit facility with NationsBank.

     3.1 ELIGIBILITY.  Each Employee who is an Employee regularly scheduled to
work at least twenty (20) hours each week and at least five (5) months each
calendar year shall be eligible to participate in the Plan as of the later of:

                                       A-2
<PAGE>   44
 
Notwithstanding the foregoing, no Employee shall be granted a Purchase Right for
an Offering Period if, immediately after the grant, the Employee would own
stock, and/or hold outstanding options to purchase stock, possessing five (5%)
percent or more of the total combined voting power or value of all classes of
stock of the Corporation or any Subsidiary. For purposes of this Section, the

                                   ARTICLE IV
 
                                STOCK AVAILABLE
 
     4.1 IN GENERAL.  Subject to the adjustments in Sections 4.2 and 4.3, an
aggregate of two hundred thousand (200,000) shares of Common Stock shall be
available for purchase by Participants pursuant to the provisions of the Plan.
These shares may be authorized and unissued shares or may be shares issued and
subsequently acquired by the Corporation. If a Purchase Right under the Plan
expires or terminates for any reason without having been exercised in whole or
part, the shares subject to such Purchase Right that are not purchased shall
again be available for subsequent Purchase Right grants under the Plan. If the
total number of shares of Common Stock for which Purchase Rights are exercised
on any Purchase Date exceeds the maximum number of shares then available under
the Plan, the Committee shall make a pro rata allocation of the shares available
in as nearly a uniform manner as shall be practicable and as it shall determine
to be equitable, and the balance of the cash credited to Participants' accounts
shall be distributed to the Participants as soon as practicable.
 
     4.2 ADJUSTMENT IN EVENT OF CHANGES IN CAPITALIZATION.  In the event of a
stock dividend, stock split or combination of shares, recapitalization or other
change in the Corporation's capitalization or other distribution with respect to
holders of the Corporation's Common Stock other than normal cash dividends, an
automatic adjustment shall be made in the number and kind of shares as to which
outstanding Purchase Rights or portions thereof then unexercised shall be
exercisable and in the available shares set forth in Section 4.1, so that the
proportionate interest of the Participants shall be maintained as before the
occurrence of such event. This adjustment in outstanding Purchase Rights shall
be made without change in the total price applicable to the unexercised portion
of such Purchase Rights and with a corresponding adjustment in the Purchase
Price per share; provided, however, that in no event shall any adjustment be
made that would cause any Purchase Right to fail to qualify as an option
pursuant to an employee stock purchase plan within the meaning of Section 423 of
the Code.
 
     4.3 DISSOLUTION, LIQUIDATION, OR MERGER.  Upon the dissolution or
liquidation of the Corporation, or upon a reorganization, merger, or
consolidation of the Corporation with one or more corporations in which the
Corporation is not the surviving corporation, or upon a sale of substantially
all of the property or stock of the Corporation to another corporation, the
holder of each Purchase Right then outstanding under the Plan shall be entitled
to receive at the next Purchase Date upon the exercise of such Purchase Right
for each share as to which such Purchase Right shall be exercised, as nearly as
reasonably may be determined, the cash, securities, or property which a holder
of one (1) share of the Common Stock was entitled to receive upon and at the
time
 
                                       A-3
<PAGE>   45
 
of such transaction. The Board shall take such steps in connection with these
transactions as the Board deems necessary or appropriate to assure that the
provisions of this Section shall thereafter be applicable, as nearly as
reasonably may be determined, in relation to the cash, securities, or property
which the holder of the Purchase Right may thereafter be entitled to receive. In
lieu of the foregoing, the Committee may terminate the Plan in accordance with
Section 8.2.
 
                                   ARTICLE V
 
                           PURCHASE RIGHT PROVISIONS
 
     5.1 PURCHASE PRICE.  The Purchase Price of a share of Common Stock
purchased for a Participant pursuant to each exercise of a Purchase Right shall
be the lesser of:
 
          (a) Eighty-five (85%) percent of the Fair Market Value of a share of
     Common Stock on the Offering Date (or if such date is not a regular
     business day, then on the first business day following the Offering Date);
     or
 
          (b) Eighty-five (85%) percent of the Fair Market Value of a share of
     Common Stock on the Purchase Date (or if such date is not a regular
     business day, then on the first business day preceding the Purchase Date).
 
     5.2 CALENDAR YEAR $25,000 LIMIT.  Notwithstanding anything else contained
herein, no Employee may be granted a Purchase Right which permits such Employee
rights to purchase Common Stock under this Plan and any other qualified employee
stock purchase plan (within the meaning of Code Section 423) of the Corporation
and its Subsidiaries to accrue at a rate which exceeds $25,000 of the Fair
Market Value of such Common Stock for each calendar year in which a Purchase
Right is outstanding at any time. For purposes of this Section, Fair Market
Value shall be determined as of the Offering Date.
 
     5.3 LIMITS FOR FIRST FOUR OFFERING PERIODS.  Notwithstanding anything else
contained herein, the maximum number of shares of Common Stock that a
participant shall be eligible to purchase with respect to each of the first four
(4) Offering Periods under the Plan is 1,250 shares per Offering Period.
 
                                   ARTICLE VI
 
                            PURCHASING COMMON STOCK
 
     6.1 PARTICIPANT'S ACCOUNT.  The Administrator shall establish a book
account in the name of each Participant. As discussed in Section 6.2 below, a
Participant's payroll deductions shall be credited to the Participant's account,
without interest, until such cash is withdrawn, distributed, or used to purchase
Common Stock as described below.
 
     During such time, if any, as the Corporation participates in a Direct
Registration System, shares of Common Stock acquired upon exercise of a Purchase
Right shall be directly registered in the name of the Participant. If the
Corporation does not participate in a Direct Registration System, then until
distribution is requested by a Participant pursuant to Article VII, stock
certificates evidencing the Participant's shares of Common Stock acquired upon
exercise of a Purchase Right shall be held by the Administrator as the nominee
for the Participant. These shares shall be credited to the Participant's
account. Certificates shall be held by the Administrator as nominee for
Participants solely as a matter of convenience. A Participant shall have all
ownership rights as to the shares credited to his or her account, and neither
the Administrator nor the Corporation shall have any ownership or other rights
of any kind with respect to any such certificates or the shares represented
thereby.
 
     All cash received or held by the Corporation under the Plan may be used by
the Corporation for any corporate purpose. The Corporation shall not be
obligated to segregate any assets held under the Plan.
 
     6.2 PAYROLL DEDUCTIONS; DIVIDENDS.  (a) Payroll Deductions.  By submitting
a Request Form at any time during an Offering Period (or in the case of the
first Offering Period, on or after 1 August 1998 for payroll
 
                                       A-4
<PAGE>   46
 
deductions beginning on or after 1 October 1998) in accordance with rules
adopted by the Committee, an Employee eligible to participate in the Plan under
Section 3.1 may authorize a payroll deduction to purchase Common Stock under the
Plan for the Offering Period. The payroll deduction shall be effective on the
first pay period commencing at least thirty (30) days after receipt of the
Request Form by the Administrator. The payroll deduction shall be in any whole
percentage up to a maximum of ten percent (10%) of such Employee's Compensation
payable each pay period, and at any other time an element of Compensation is
payable. A Participant's payroll deduction shall not be less than one (1%)
percent of such Employee's Compensation payable each payroll period.
 
     (b) Dividends.  Dividends paid on Common Stock which are credited to a
Participant's account as of the dividend payment date shall be paid to the
Participant as soon as practicable.
 
     6.3 DEDUCTION CHANGES AND DISCONTINUANCE.  A Participant may increase,
decrease or completely discontinue his or her payroll deductions by filing a new
Request Form with the Administrator. This increase, decrease or discontinuance
shall be effective on the first pay period commencing at least thirty (30) days
after receipt of the Request Form by the Administrator. A Participant who
discontinues his or her payroll deductions may not resume participation in the
Plan until the following Offering Period.
 
     Any amount held in the Participant's account after the effective date of
the discontinuance of his or her payroll deductions will either be refunded or
used to purchase Common Stock in accordance with Section 7.1.
 
     6.4 LEAVE OF ABSENCE; TRANSFER TO INELIGIBLE STATUS.  If a Participant
either begins a leave of absence, is transferred to employment with a Subsidiary
not participating in the Plan, or remains employed with an Employer but is no
longer eligible to participate in the Plan, the Participant shall cease to be
eligible for payroll deductions to his or her account pursuant to Section 6.2.
The cash standing to the credit of the Participant's account shall become
subject to the provisions of Section 7.1.
 
     If the Participant returns from the leave of absence before being deemed to
have ceased employment with the Employer under Section 3.2, or again becomes
eligible to participate in the Plan, the Request Form, if any, in effect
immediately before the leave of absence or disqualifying change in employment
status shall be deemed void and the Participant must again complete a new
Request Form to resume participation in the Plan.
 
     6.5 AUTOMATIC EXERCISE.  Unless the cash credited to a Participant's
account is withdrawn or distributed as provided in Article VII, his or her
Purchase Right shall be deemed to have been exercised automatically on each
Purchase Date, for the purchase of the number of full shares of Common Stock
which the cash credited to his or her account at that time will purchase at the
Purchase Price. The cash balance, if any, remaining in the Participant's account
at the end of an Offering Period shall be carried over to the next Offering
Period, without interest. The amount of cash that may be used to purchase shares
of Common Stock may not exceed the Compensation restrictions set forth in
Section 6.2.
 
     If the cash credited to a Participant's account on the Purchase Date
exceeds the applicable Compensation restrictions of Section 6.2 or exceeds the
amount necessary to purchase the maximum number of shares of Common Stock
available during the Offering Period, such excess cash shall be refunded to the
Participant. The excess cash may not be used to purchase shares of Common Stock
under the Plan nor retained in the Participant's account for a future Offering
Period.
 
     Each Participant shall receive a statement on at least an annual basis
indicating the number of shares credited to his or her account under the Plan.
 
     6.6 LISTING, REGISTRATION, AND QUALIFICATION OF SHARES.  The granting of
Purchase Rights for, and the sale and delivery of, Common Stock under the Plan
shall be subject to the effecting by the Corporation of any listing,
registration, or qualification of the shares subject to that Purchase Right upon
any securities exchange or under any federal or state law, or the obtaining of
the consent or approval of any governmental regulatory body deemed necessary or
desirable for the issuance or purchase of the shares covered.

     7.1 DISCONTINUANCE OF DEDUCTIONS; LEAVE OF ABSENCE; TRANSFER TO INELIGIBLE
STATUS.  In the event of a Participant's complete discontinuance of payroll
deductions under Section 6.3 or a Participant's leave of absence or transfer to
an ineligible status under Section 6.4, the cash balance then standing to the
credit of the Participant's account shall be:
 
          (a) returned to the Participant, in cash, without interest, as soon as
     practicable, upon the Participant's written request received by the
     Administrator at least thirty (30) days before the next Purchase Date; or
 
          (b) held under the Plan and used to purchase Common Stock for the
     Participant under the automatic exercise provisions of Section 6.5.
 
     7.2 IN-SERVICE WITHDRAWALS.  During such time, if any, as the Corporation
participates in a Direct Registration System, shares of Common Stock acquired
upon exercise of a Purchase Right shall be directly registered in the name of
the Participant and the Participant may withdraw certificates in accordance with
the applicable terms and conditions of such Direct Registration System. If the
Corporation does not participate in a Direct Registration System, (i) a
Participant may, while an Employee of the Corporation or any Subsidiary,
withdraw certificates for some or all of the shares of Common Stock credited to
his or her account at any time, upon thirty (30) days' written notice to the
Administrator, and (ii) each Participant shall be permitted only one withdrawal
under this Section each calendar quarter. If a Participant requests a
distribution of only a portion of the shares of Common Stock credited to his or
her account, the Administrator will distribute the oldest securities held in the
Participant's Account first, using a first in-first out methodology.
 
     7.3 TERMINATION OF EMPLOYMENT FOR REASONS OTHER THAN DEATH.  If a
Participant terminates employment with the Corporation and the Subsidiaries for
reasons other than death, the cash balance in the Participant's account shall be
returned to the Participant in cash, without interest, as soon as practicable.
Certificates for the shares of Common Stock credited to his or her account shall
be distributed to the Participant as soon as practicable, unless the Corporation
then participates in a Direct Registration System, in which case, the
Participant shall be entitled to evidence of ownership of such shares in such
form as the terms and conditions of such Direct Registration System permit.
 
     7.4 DEATH.  In the event a Participant dies, the cash balance in his or her
account shall be distributed to the Participant's beneficiary, in cash, without
interest, as soon as practicable. Certificates for the shares of Common Stock
credited to the Participant's account shall be distributed to the beneficiary as
soon as practicable, unless the Corporation then participates in a Direct
Registration System, in which case, the beneficiary shall be entitled to
evidence of ownership of such shares in such form as the terms and conditions of
such Direct Registration System permit.
 
     In the event of the Participant's death, the Participant's beneficiary
shall be the person or entity identified on the Participant's employee data
record maintained by the Corporation or on such other form as determined by the
Administrator. This designation of beneficiary may be changed by the Participant
in accordance with procedures established by the Administrator.
 
     7.5 REGISTRATION.  Whether represented in certificate form or by direct
registration pursuant to a Direct Registration System, shares of Common Stock
acquired upon exercise of a Purchase Right shall be directly registered in the
name of the Participant or, if the Participant so indicates on the Request Form,
(a) in the Participant's name jointly with a member of the Participant's family,
with the right of survivorship, (b) in the name of a custodian for the
Participant (in the event the Participant is under a legal disability to have
stock issued in the Participant's name), or (c) in a manner giving effect to the
status of such shares as community property. No other names may be included in
the Common Stock registration. The Corporation shall pay all issue or transfer
taxes with respect to the issuance or transfer of shares of such Common Stock,
as well as all fees and expenses necessarily incurred by the Corporation in
connection with such issuance or transfer.

Plan, in full or in part, at any time and from time to time; provided, however,
that no amendment or modification shall:
 
          (a) affect any right or obligation with respect to any grant
     previously made, unless required by law, or
 
          (b) unless previously approved by the stockholders of the Corporation,
     where such approval is necessary to satisfy federal securities laws, the
     Code, or rules of any stock exchange on which the Corporation's Common
     Stock is listed:
 
             (1) in any manner materially affect the eligibility requirements

     The purpose of this Medirisk, Inc. 1998 Long-Term Incentive Plan (the
"Plan") is to promote the success, and enhance the value, of Medirisk, Inc. (the
"Corporation"), by linking the personal interests of its employees, officers and
directors to those of Corporation stockholders and by providing its employees,
officers and directors with an incentive for outstanding performance. The Plan
is further intended to provide flexibility to the Corporation in its ability to
motivate, attract, and retain the services of employees, officers and directors
upon whose judgment, interest, and special effort the successful conduct of the
Corporation's operation is largely dependent. Accordingly, the Plan permits the
grant of incentive awards from time to time to selected employees, officers and
directors

                                 EFFECTIVE DATE

by the Board. However, the Plan shall be submitted to the stockholders of the
Corporation for approval within twelve (12) months of the Board's approval
thereof. No Incentive Stock Options granted under the Plan may be exercised
prior to approval of the Plan by the stockholders, and if the stockholders fail
to approve the Plan within twelve months of the Board's approval hereof, any
Incentive Stock Options previously granted hereunder shall be automatically
converted to Nonqualified Stock Options without any further act. In the
discretion of the Committee, Awards may be made to Covered Employees which are
intended to constitute qualified performance-based compensation under Code
Section 162(m). Any such Awards shall be contingent upon the stockholders having
approved the Plan.

          (a) Exercise Price.  The exercise price per share of Stock under an
     Option shall be determined by the Committee.

     the time or times at which an Option may be exercised in whole or in part.

     exercised. The Committee may waive any exercise provisions at any time in
     whole or in part based upon factors as the Committee may determine in its
     sole discretion so that the Option becomes exercisable at an earlier date.
 
                                       B-5
<PAGE>   55
 
          (c) Payment.  The Committee shall determine the methods by which the
     exercise price of an Option may be paid, the form of payment, including,
     without limitation, cash, shares of Stock, or other property (including
     "cashless exercise" arrangements), and the methods by which shares of Stock
     shall be delivered or deemed to be delivered to Participants; provided,
     however, that if shares of Stock are used to pay the exercise price of an
     Option, such shares must have been held by the Participant for at least six
     (6) months. Without limiting the power and discretion conferred on the
     Committee pursuant to the preceding sentence, the Committee may, in the
     exercise of its discretion, but need not, allow a Participant to pay the
     Option price by directing the Corporation to withhold from the shares of
     Stock that would otherwise be issued upon exercise of the Option that
     number of shares having a Fair Market Value on the exercise date equal to
     the Option price, all as determined pursuant to rules and procedures
     established by the Committee.
 
          (d) Evidence of Grant.  All Options shall be evidenced by a written
     Award Agreement between the Corporation and the Participant. The Award
     Agreement shall include such provisions, not inconsistent with the Plan, as
     may be specified by the Committee.
 
     7.2 INCENTIVE STOCK OPTIONS.  The terms of any Incentive Stock Options
granted under the Plan must comply with the following additional rules:
 
          (a) Exercise Price.  The exercise price per share of Stock shall be
     set by the Committee, provided that the exercise price for any Incentive
     Stock Option shall not be less than the Fair Market Value as of the date of
     the grant.
 
          (b) Exercise.  In no event may any Incentive Stock Option be
     exercisable for more than ten (10) years from the date of its grant.
 
          (c) Lapse of Option.  An Incentive Stock Option shall lapse under the
     earliest of the following circumstances; provided, however, that the
     Committee may, prior to the lapse of the Incentive Stock Option under the
     circumstances described in paragraphs (3), (4) and (5) below, provide in
     writing that the Option will extend until a later date, but if Option is
     exercised after the dates specified in paragraphs (3), (4) and (5) below,
     it will automatically become a Nonqualified Stock Option:
 
             (1) The Incentive Stock Option shall lapse as of the option
        expiration date set forth in the Award Agreement.
 
             (2) The Incentive Stock Option shall lapse ten (10) years after it
        is granted, unless an earlier time is set in the Award Agreement.
 
             (3) If the Participant terminates employment for any reason other
        than as provided in paragraph (4) or (5) below, the Incentive Stock
        Option shall lapse, unless it is previously exercised, three months
        after the Participant's termination of employment; provided, however,
        that if the Participant's employment is terminated by the Corporation
        for cause or by the Participant without the consent of the Corporation,
        the Incentive Stock Option shall (to the extent not previously
        exercised) lapse immediately.
 
             (4) If the Participant terminates employment by reason of his
        Disability, the Incentive Stock Option shall lapse, unless it is
        previously exercised, one year after the Participant's termination of
        employment.
 
             (5) If the Participant dies while employed, or during the
        three-month period described in paragraph (3)or during the one-year
        period described in paragraph (4) and before the Option otherwise
        lapses, the Option shall lapse one (1) year after the Participant's
        death. Upon the Participant's death, any exercisable Incentive Stock
        Options may be exercised by the Participant's beneficiary, determined in
        accordance with Section 13.6.
 
     Unless the exercisability of the Incentive Stock Option is accelerated as
provided in Article XIII, if a Participant exercises an Option after termination
of employment, the Option may be exercised only with respect to the shares that
were otherwise vested on the Participant's termination of employment.

     (d) Individual Dollar Limitation.  The aggregate Fair Market Value
(determined as of the time an Award is made) of all shares of Stock with respect
to which Incentive Stock Options are first exercisable by a Participant in any
calendar year may not exceed One Hundred Thousand and No/100 ($100,000.00)
Dollars.
 
     (e) Ten Percent Owners.  No Incentive Stock Option shall be granted to any
individual who, at the date of grant, owns stock possessing more than ten (10%)
percent of the total combined voting power of all classes of stock of the
Corporation or any Parent or Subsidiary unless the exercise price per share of
such Option is at least one hundred ten (110%) percent of the Fair Market Value
per share of Stock at the date of grant and the Option expires no later than
five (5) years after the date of grant.
 
     (f) Expiration of Incentive Stock Options.  No Award of an Incentive Stock
Option may be made pursuant to the Plan after the day immediately prior to the
tenth (10th) anniversary of the Effective Date.
 
     (g) Right to Exercise.  During a Participant's lifetime, an Incentive Stock
Option may be exercised only by the Participant or, in the case of the
Participant's Disability, by the Participant's guardian or legal representative.
 
     (h) Directors.  The Committee may not grant an Incentive Stock Option to a
nonemployee director. The Committee may grant an Incentive Stock Option to a
director who is also an employee of the Corporation or Parent or Subsidiary but
only in that individual's position as an employee and not as a director.

                           STOCK APPRECIATION RIGHTS
 
     The Committee is authorized to grant SARs to Participants on the following
terms and conditions:
 
          (a) Right to Payment.  Upon the exercise of a Stock Appreciation
     Right, the Participant to whom it is granted has the right to receive the
     excess, if any, of:
 
             (1) The Fair Market Value of one (1) share of Stock on the date of
        exercise; over
 
             (2) The grant price of the Stock Appreciation Right as determined
        by the Committee, which shall not be less than the Fair Market Value of
        one (1) share of Stock on the date of grant in the case of any SAR
        related to an Incentive Stock Option.
 
          (b) Other Terms.  All awards of Stock Appreciation Rights shall be
     evidenced by an Award Agreement. The terms, methods of exercise, methods of
     settlement, form of consideration payable in settlement, and any other
     terms and conditions of any Stock Appreciation Right shall be determined by
     the Committee at the time of the grant of the Award and shall be reflected
     in the Award Agreement.
 
                                   ARTICLE IX
 
                               PERFORMANCE SHARES
 
     9.1 GRANT OF PERFORMANCE SHARES.  The Committee is authorized to grant
Performance Shares to Participants on such terms and conditions as may be
selected by the Committee. The Committee shall have the complete discretion to
determine the number of Performance Shares granted to each Participant. All
Awards of Performance Shares shall be evidenced by an Award Agreement.
 
     9.2 RIGHT TO PAYMENT.  A grant of Performance Shares gives the Participant
rights, valued as determined by the Committee, and payable to, or exercisable
by, the Participant to whom the Performance Shares are granted, in whole or in
part, as the Committee shall establish at grant or thereafter. The Committee
shall set performance goals and other terms or conditions to payment of the
Performance Shares in its discretion which, depending on the extent to which
they are met, will determine the number and value of Performance Shares that
will be paid to the Participant.
 
     9.3 OTHER TERMS.  Performance Shares may be payable in cash, Stock, or
other property, and have such other terms and conditions as determined by the
Committee and reflected in the Award Agreement.

                            RESTRICTED STOCK AWARDS
 
     10.1 GRANT OF RESTRICTED STOCK.  The Committee is authorized to make Awards
of Restricted Stock to Participants in such amounts and subject to such terms
and conditions as may be selected by the Committee. All Awards of Restricted
Stock shall be evidenced by a Restricted Stock Award Agreement.
 
     10.2 ISSUANCE AND RESTRICTIONS.  Restricted Stock shall be subject to such
restrictions on transferability and other restrictions as the Committee may
impose (including, without limitation, limitations on the right to vote
Restricted Stock or the right to receive dividends on the Restricted Stock).
These restrictions may lapse separately or in combination at such times, under
such circumstances, in such installments, upon the satisfaction of performance
goals or otherwise, as the Committee determines at the time of the grant of the
Award or thereafter.
 
     10.3 FORFEITURE.  Except as otherwise determined by the Committee at the
time of the grant of the Award or thereafter, upon termination of employment
during the applicable restriction period or upon failure to satisfy a
performance goal during the applicable restriction period, Restricted Stock that
is at that time subject to restrictions shall be forfeited and reacquired by the
Corporation; provided, however, that the Committee may provide in any Award
Agreement that restrictions or forfeiture conditions relating to Restricted
Stock will be waived in whole or in part in the event of terminations resulting
from specified causes, and the Committee may in other cases waive in whole or in
part restrictions or forfeiture conditions relating to Restricted Stock.
 
     10.4 CERTIFICATES FOR RESTRICTED STOCK.  Restricted Stock granted under the
Plan may be evidenced in such manner as the Committee shall determine. If
certificates representing shares of Restricted Stock are registered in the name
of the Participant, certificates must bear an appropriate legend referring to
the terms, conditions, and restrictions applicable to such Restricted Stock.
 
                                   ARTICLE XI
 
                              DIVIDEND EQUIVALENTS
 
     The Committee is authorized to grant Dividend Equivalents to Participants
subject to such terms and conditions as may be selected by the Committee.
Dividend Equivalents shall entitle the Participant to receive payments equal to
dividends with respect to all or a portion of the number of shares of Stock
subject to an Award, as determined by the Committee. The Committee may provide
that Dividend Equivalents be paid or distributed when accrued or be deemed to
have been reinvested in additional shares of Stock, or otherwise reinvested.
 
                                  ARTICLE XII
 
                            OTHER STOCK-BASED AWARDS
 
     The Committee is authorized, subject to limitations under applicable law,
to grant to Participants such other Awards that are payable in, valued in whole
or in part by reference to, or otherwise based on or related to shares of Stock,
as deemed by the Committee to be consistent with the purposes of the Plan,
including without limitation shares of Stock awarded purely as a "bonus" and not
subject to any restrictions or conditions, convertible or exchangeable debt
securities, other rights convertible or exchangeable into shares of Stock, and
Awards valued by reference to book value of shares of Stock or the value of
securities of or the performance of specified Parents or Subsidiaries. The
Committee shall determine the terms and conditions of such Awards.

                                  ARTICLE XIII
 
                        PROVISIONS APPLICABLE TO AWARDS
 
     13.1 STAND-ALONE, TANDEM AND SUBSTITUTE AWARDS.  Awards granted under the
Plan may, in the discretion of the Committee, be granted either alone or in
addition to, in tandem with, or in substitution for, any other Award granted
under the Plan. If an Award is granted in substitution for another Award, the
Committee may require the surrender of such other Award in consideration of the
grant of the new Award. Awards granted in addition to or in tandem with other
Awards may be granted either at the same time as or at a different time from the
grant of such other Awards.
 
     13.2 EXCHANGE PROVISIONS.  The Committee may at any time offer to exchange
or buy out any previously granted Award for a payment in cash, Stock, or another
Award (subject to Article XIV), based on the terms and conditions the Committee
determines and communicates to the Participant at the time the offer is made.
 
     13.3 TERM OF AWARD.  The term of each Award shall be for the period as
determined by the Committee, provided that in no event shall the term of any
Incentive Stock Option or a Stock Appreciation Right granted in tandem with the
Incentive Stock Option exceed a period of ten (10) years from the date of its
grant (or, if Section 7.2(e) applies, five (5) years from the date of its
grant).
 
     13.4 FORM OF PAYMENT FOR AWARDS.  Subject to the terms of the Plan and any
applicable law or Award Agreement, payments or transfers to be made by the
Corporation or a Parent or Subsidiary on the grant or exercise of an Award may
be made in such form as the Committee determines at or after the time of grant,
including without limitation, cash, Stock, other Awards, or other property, or
any combination, and may be made in a single payment or transfer, in
installments, or on a deferred basis, in each case determined in accordance with
rules adopted by, and at the discretion of, the Committee.
 
     13.5 LIMITS ON TRANSFER.  No right or interest of a Participant in any
unexercised or restricted Award may be pledged, encumbered, or hypothecated to
or in favor of any party other than the Corporation or a Parent or Subsidiary,
or shall be subject to any lien, obligation, or liability of such Participant to
any other party other than the Corporation or a Parent or Subsidiary. No
unexercised or restricted Award shall be assignable or transferable by a
Participant other than by will or the laws of descent and distribution or,
except in the case of an Incentive Stock Option, pursuant to a domestic
relations order that would satisfy Section 414(p)(1)(A) of the Code if such
Section applied to an Award under the Plan; provided, however, that the
Committee may (but need not) permit other transfers where the Committee
concludes that such transferability (i) does not result in accelerated taxation,
(ii) does not cause any Option intended to be an incentive stock option to fail
to be described in Code Section 422(b), and (iii) is otherwise appropriate and
desirable, taking into account any factors deemed relevant, including without
limitation, state or federal tax or securities laws applicable to transferable
Awards.
 
     13.6 BENEFICIARIES.  Notwithstanding Section 13.5, a Participant may, in
the manner determined by the Committee, designate a beneficiary to exercise the
rights of the Participant and to receive any distribution with respect to any
Award upon the Participant's death. A beneficiary, legal guardian, legal
representative, or other person claiming any rights under the Plan is subject to
all terms and conditions of the Plan and any Award Agreement applicable to the
Participant, except to the extent the Plan and Award Agreement otherwise
provide, and to any additional restrictions deemed necessary or appropriate by
the Committee. If no beneficiary has been designated or survives the
Participant, payment shall be made to the Participant's estate. Subject to the
foregoing, a beneficiary designation may be changed or revoked by a Participant
at any time provided the change or revocation is filed with the Committee.
 
     13.7 STOCK CERTIFICATES.  All Stock certificates delivered under the Plan
are subject to any stop-transfer orders and other restrictions as the Committee
deems necessary or advisable to comply with federal or state securities laws,
rules and regulations and the rules of any national securities exchange or
automated quotation system on which the Stock is listed, quoted, or traded. The
Committee may place legends on any Stock certificate to reference restrictions
applicable to the Stock.

<PAGE>   59
 
     13.8 ACCELERATION UPON DEATH OR DISABILITY.  Notwithstanding any other
provision in the Plan or any Participant's Award Agreement to the contrary, upon
the Participant's death or Disability during his employment or service as a
director, all outstanding Options, Stock Appreciation Rights, and other Awards
in the nature of rights that may be exercised shall become fully exercisable and
all restrictions on outstanding Awards shall lapse. Any Option or Stock
Appreciation Rights Awards shall thereafter continue or lapse in accordance with
the other provisions of the Plan and the Award Agreement. To the extent that
this provision causes Incentive Stock Options to exceed the dollar limitation
set forth in Section 7.2(d), the excess Options shall be deemed to be
Nonqualified Stock Options.
 
     13.9 ACCELERATION UPON A CHANGE-IN-CONTROL.  Except as otherwise provided
in the Award Agreement, upon the occurrence of a Change-in-Control, all
outstanding Options, Stock Appreciation Rights, and other Awards in the nature
of rights that may be exercised shall become fully exercisable and all
restrictions on outstanding Awards shall lapse; provided, however, that such
acceleration will not occur if, in the opinion of the Company's accountants,
such acceleration would preclude the use of "pooling of interest" accounting
treatment for a Change-in-Control transaction that (a) would otherwise qualify
for such accounting treatment, and (b) is contingent upon qualifying for such
accounting treatment. To the extent that this provision causes Incentive Stock
Options to exceed the dollar limitation set forth in Section 7.2(d), the excess
Options shall be deemed to be Nonqualified Stock Options.
 
     13.10 ACCELERATION UPON CERTAIN EVENTS NOT CONSTITUTING A
CHANGE-IN-CONTROL.  In the event of the occurrence of any circumstance,
transaction or event not constituting a Change-in-Control (as defined in Article
III) but which the Board of Directors deems to be, or to be reasonably likely to
lead to, an effective Change-in-Control of the Company of a nature that would be
required to be reported in response to Item 6(e) of Schedule 14A of the 1934
Act, the Committee may in its sole discretion declare all outstanding Options,
Stock Appreciation Rights, and other Awards in the nature of rights that may be
exercised to be fully exercisable, and/or all restrictions on all outstanding
Awards to have lapsed, in each case, as of such date as the Committee may, in
its sole discretion, declare, which may be on or before the consummation of such
transaction or event. To the extent that this provision causes Incentive Stock
Options to exceed the dollar limitation set forth in Section 7.2(d), the excess
Options shall be deemed to be Nonqualified Stock Options.
 
     13.11 ACCELERATION FOR ANY OTHER REASON.  Regardless of whether an event
has occurred as described in Section 13.9 or 13.10 above, the Committee may in
its sole discretion at any time determine that all or a portion of a
Participant's Options, Stock Appreciation Rights, and other Awards in the nature
of rights that may be exercised shall become fully or partially exercisable,
and/or that all or a part of the restrictions on all or a portion of the
outstanding Awards shall lapse, in each case, as of such date as the Committee
may, in its sole discretion, declare. The Committee may discriminate among
Participants and among Awards granted to a Participant in exercising its
discretion pursuant to this Section 13.11.
 
     13.12 EFFECT OF ACCELERATION.  If an Award is accelerated under Section
13.9 or 13.10, the Committee may, in its sole discretion, provide (i) that the
Award will expire after a designated period of time after such acceleration to
the extent not then exercised, (ii) that the Award will be settled in cash
rather than Stock, (iii) that the Award will be assumed by another party to the
transaction giving rise to the acceleration or otherwise be equitably converted
in connection with such transaction, or (iv) any combination of the foregoing.
The Committee's determination need not be uniform and may be different for
different Participants whether or not such Participants are similarly situated.
 
     13.13 PERFORMANCE GOALS.  The Committee may determine that any Award
granted pursuant to this Plan to a Participant (including, but not limited to,
Participants who are Covered Employees) shall be determined solely on the basis
of (a) the achievement by the Corporation or a Parent or Subsidiary of a
specified target return, or target growth in return, on equity or assets, (b)
the Corporation's, Parent's or Subsidiary's stock price, (c) the achievement by
a business unit of the Corporation, Parent or Subsidiary of a specified target,
or target growth in, net income or earnings per share, or (d) any combination of
the goals set forth in (a) through (c) above. Furthermore, the Committee
reserves the right for any reason to reduce (but not increase) any Award,
notwithstanding the achievement of a specified goal. If an Award is made on such
basis, the Committee shall establish goals prior to the beginning of the period
for which such performance goal
 
                                      B-10
<PAGE>   60
 
relates (or such later date as may be permitted under Code Section 162(m) or the
regulations thereunder). Any payment of an Award granted with performance goals
shall be conditioned on the written certification of the Committee in each case
that the performance goals and any other material conditions were satisfied.
 
     13.14 TERMINATION OF EMPLOYMENT.  Whether military, government or other
service or other leave of absence shall constitute a termination of employment
shall be determined in each case by the Committee at its discretion, and any
determination by the Committee shall be final and conclusive. A termination of
employment shall not occur in a circumstance in which a Participant transfers
from the Corporation to one of its Parents or Subsidiaries, transfers from a
Parent or Subsidiary to the Corporation, or transfers from one Parent or
Subsidiary to another Parent or Subsidiary.
 
     13.15 LOAN PROVISIONS.  With the consent of the Committee, the Corporation
may make, guarantee or arrange for a loan or loans to a Participant with respect
to the exercise of any Option granted under this Plan and/or with respect to the
payment of the purchase price, if any, of any Award granted hereunder and/or
with respect to the payment by the Participant of any or all federal and/or
state income taxes due on account of the granting or exercise of any Award
hereunder. The Committee shall have full authority to decide whether to make a
loan or loans hereunder and to determine the amount, terms and provisions of any
such loan or loans, including the interest rate to be charged in respect of any
such loan or loans, whether the loan or loans are to be made with or without
recourse against the borrower, the terms on which the loan is to be repaid and
the conditions, if any, under which the loan or loans may be forgiven.
 
                                  ARTICLE XIV
 
                          CHANGES IN CAPITAL STRUCTURE
 
     In the event a stock dividend is declared upon the Stock, the shares of
Stock then subject to each Award shall be increased proportionately without any
change in the aggregate purchase price therefor. In the event the Stock shall be
changed into or exchanged for a different number or class of shares of stock or
securities of the Corporation or of another corporation, whether through
reorganization, recapitalization, reclassification, stock split-up, combination
of shares, merger or consolidation, there shall be substituted for each such
share of Stock then subject to each Award the number and class of shares into
which each outstanding share of Stock shall be so exchanged, all without any
change in the aggregate purchase price for the shares then subject to each
Award.
 
                                   ARTICLE XV
 
                    AMENDMENT, MODIFICATION AND TERMINATION
 
     15.1 AMENDMENT, MODIFICATION AND TERMINATION.  The Board may, at any time
and from time to time, amend, modify or terminate the Plan without stockholder
approval; provided, however, that the Board or Committee may condition any
amendment or modification on the approval of stockholders of the Corporation if
such approval is necessary or deemed advisable with respect to tax, securities
or other applicable laws, policies or regulations.
 
     15.2 AWARDS PREVIOUSLY GRANTED.  At any time and from time to time, the
Committee may amend, modify or terminate any outstanding Award without approval
of the Participant; provided, however, that such amendment, modification or
termination shall not, without the Participant's consent, reduce or diminish the
value of such Award determined as if the Award had been exercised, vested,
cashed in or otherwise settled on the date of such amendment or termination. No
termination, amendment, or modification of the Plan shall adversely affect any
Award previously granted under the Plan, without the written consent of the
Participant.

                               GENERAL PROVISIONS
 
     16.1 NO RIGHTS TO AWARDS.  No Participant or employee, officer or director
shall have any claim to be granted any Award under the Plan, and neither the
Corporation nor the Committee is obligated to treat Participants and employees,
officers or directors uniformly.
 
     16.2 NO STOCKHOLDER RIGHTS.  No Award gives the Participant any of the
rights of a stockholder of the Corporation unless and until shares of Stock are
in fact issued to such person in connection with such Award.
 
     16.3 WITHHOLDING.  The Corporation or any Parent or Subsidiary shall have
the authority and the right to deduct or withhold, or require a Participant to
remit to the Corporation, an amount sufficient to satisfy federal, state, and
local taxes (including the Participant's FICA obligation) required by law to be
withheld with respect to any taxable event arising as a result of the Plan. With
respect to withholding required upon any taxable event under the Plan, the
Committee may, at the time the Award is granted or thereafter, require that any
such withholding requirement be satisfied, in whole or in part, by withholding
shares of Stock having a Fair Market Value on the date of withholding equal to
the amount to be withheld for tax purposes, all in accordance with such
procedures as the Committee establishes.
 
     16.4 NO RIGHT TO EMPLOYMENT OR DIRECTORSHIP.  Nothing in the Plan or any
Award Agreement shall interfere with or limit in any way the right of the
Corporation or any Parent or Subsidiary to terminate any Participant's
employment or status as an officer, director or consultant at any time, nor
confer upon any Participant any right to continue as an employee, officer,
director or consultant of the Corporation or any Parent or Subsidiary.
 
     16.5 UNFUNDED STATUS OF AWARDS.  The Plan is intended to be an "unfunded"
plan for incentive and deferred compensation. With respect to any payments not
yet made to a Participant pursuant to an Award, nothing contained in the Plan or
any Award Agreement shall give the Participant any rights that are greater than
those of a general creditor of the Corporation or any Parent or Subsidiary.
 
     16.6 RELATIONSHIP TO OTHER BENEFITS.  No payment under the Plan shall be
taken into account in determining any benefits under any pension, retirement,
savings, profit sharing, group insurance, welfare or benefit plan of the
Corporation or any Parent or Subsidiary unless provided otherwise in such other
plan.
 
     16.7 EXPENSES.  The expenses of administering the Plan shall be borne by
the Corporation and its Parents or Subsidiaries.
 
     16.8 TITLES AND HEADINGS.  The titles and headings of the Sections in the
Plan are for convenience of reference only, and in the event of any conflict,
the text of the Plan, rather than such titles or headings, shall control.
 
     16.9 GENDER AND NUMBER.  Except where otherwise indicated by the context,
any masculine term used herein also shall include the feminine; the plural shall
include the singular and the singular shall include the plural.
 
     16.10 FRACTIONAL SHARES.  No fractional shares of Stock shall be issued and
the Committee shall determine, in its discretion, whether cash shall be given in
lieu of fractional shares or whether such fractional shares shall be eliminated
by rounding up.
 
     16.11 GOVERNMENT AND OTHER REGULATIONS.  The obligation of the Corporation
to make payment of awards in Stock or otherwise shall be subject to all
applicable laws, rules, and regulations, and to such approvals by government
agencies as may be required. The Corporation shall be under no obligation to
register under the 1933 Act, or any state securities act, any of the shares of
Stock paid under the Plan. The shares paid under the Plan may in certain
circumstances be exempt from registration under the 1933 Act, and the
Corporation may restrict the transfer of such shares in such manner as it deems
advisable to ensure the availability of any such exemption.

     16.12 GOVERNING LAW.  To the extent not governed by federal law, the Plan
and all Award Agreements shall be construed in accordance with and governed by
the laws of the State of Delaware.
 
     16.13 ADDITIONAL PROVISIONS.  Each Award Agreement may contain such other
terms and conditions as the Committee may determine, provided that such other
terms and conditions are not inconsistent with the provisions of the Plan.
 
     16.14 CODE SECTION 162(M).  The deduction limits of Code Section 162(m) and
the regulations thereunder shall not apply to compensation payable under the
Plan until the expiration of the reliance period described in Treasury
Regulation 1.162-27(f) or any successor regulation.

                    ACQUISITION AGREEMENT AND PLAN OF MERGER
 
     THIS ACQUISITION AGREEMENT AND PLAN OF MERGER (this "Agreement"), is made
this 26th day of March 1998, by and among Medirisk, Inc., a Delaware corporation
("Medirisk"), HEALTHDEMOGRAPHICS, INC., a Delaware corporation and wholly-owned
subsidiary of Medirisk ("Merger Sub"), HEALTHDEMOGRAPHICS, a California
corporation (the "Company"), and those shareholders of the Company executing and
delivering this Agreement (all of the shareholders of the Company being
collectively referred to as the "Shareholders," and each individually as a
"Shareholder").
 
                             W I T N E S S E T H :
 
     WHEREAS, the parties desire to enter into this Agreement pursuant to which
the Company will merge with and into Merger Sub, such that Medirisk will

     1.6 TAX EFFECT.  Medirisk, the Company and the Signing Shareholders intend
the Merger be a reorganization within the meaning of Section 368 of the Internal
Revenue Code of 1986, as amended (a "Reorganization" and the "Code,"
respectively). In connection with that intention, the persons indicated below
make the following representations and warranties.
 
     (a) The Company represents and warrants to Medirisk and Merger Sub that,
except as otherwise disclosed in the Schedules to this Agreement, the Company
has not taken or agreed to take any action, nor does the Company have any
Knowledge of any fact or circumstance that is reasonably likely to prevent the
Merger from qualifying as a Reorganization. The Company agrees to use reasonable
efforts to cause the Merger to qualify, and not to take action which would cause
the Merger not to qualify, as a Reorganization. As used in this Agreement, when
any statement is made to the "Knowledge" of a person, it means to the actual
knowledge of such person without any duty on the part of such person to
independently investigate or confirm the accuracy of such statement.
 
     (b) Medirisk and the Merger Sub represent and warrant to the Company and
the Shareholders of the Company that, except as otherwise disclosed in the
Schedules to this Agreement, neither Medirisk nor the Merger Sub has taken or
agreed to take any action, nor do either of Medirisk or the Merger Sub have any
Knowledge of any fact or circumstance that is reasonably likely, to prevent the
Merger from qualifying as a Reorganization. Medirisk and the Merger Sub agree to
use reasonable efforts to cause the Merger to qualify, and not to take action
which would cause the Merger not to qualify, as a Reorganization; provided,
however, that nothing in this Section 1.6 shall affect the Shareholders' right
to receive the Additional Consideration as described in this Agreement.
 
     (c) Medirisk, the Merger Sub, the Company and the Signing Shareholders
understand that (i) neither Medirisk, the Merger Sub, the Company, nor any of
the Shareholders makes any representation or warranty that the Merger will be
regarded as a Reorganization, (ii) the Closing is not subject to a condition
that an Internal Revenue Service ruling or tax opinion be obtained as to the
federal income tax consequences of this Agreement or the Merger, and (iii)
Medirisk, the Merger Sub, the Company and the Shareholders will rely solely upon
their respective advisors for advice concerning the tax consequences of the
Merger.
 
     (d) The Company represents that, in the Merger, Merger Sub will acquire
assets representing at least ninety percent (90%) of the fair market value of
the net assets and at least seventy percent (70%) of the fair market value of
the gross assets held by the Company immediately prior to the Merger. For this
purpose, all redemptions and distributions (except for regular, normal
dividends) made by the Company immediately preceding the Merger and all amounts
paid out of the assets of the Company as Reorganization expenses will be
considered as assets held by the Company immediately prior to the Merger. In
addition, assets disposed of in contemplation of the Merger will be considered
as assets held by the Company immediately prior to the Merger.
 
     (e) The Company warrants that the liabilities of the Company to be assumed
by Merger Sub or Medirisk in the Merger (and the liabilities to which the assets
to be transferred are subject) were incurred or will be incurred by the Company
in the ordinary course of its business.
 
                                       C-3
<PAGE>   66
 
     (f) Medirisk and Merger Sub warrant that there is not now, nor will there
be at the time of the Merger Effective Time, any intercorporate indebtedness
existing between the Company and Medirisk or between Company and Merger Sub that
was issued, acquired, or will be settled at a discount.
 
     (g) The Company represents that the Shareholders will pay, or reimburse the
Company as provided in Section 10.5 below, direct costs and expenses incurred by
the Shareholders, or by the Company on their behalf, in connection with the
Merger. Medirisk, Merger Sub, and the Company will pay their respective
expenses, if any, incurred in connection with the Merger.
 
     (h) Each of Medirisk, Merger Sub and the Company represents that it is not
an Investment Company. As used in this Section 1.6(h), "Investment Company"
means a regulated investment company, a real estate investment trust, or a
corporation 50 percent or more of the value of whose total assets are stock and
securities and 80 percent or more of the value of whose total assets are assets
held for investment. In making the 50-percent and 80-percent determinations
under the preceding sentence, stock and securities in any subsidiary corporation
shall be disregarded and the parent corporation shall be deemed to own its
ratable share of the subsidiary's assets, and a corporation shall be considered
a subsidiary if the parent owns 50 percent or more of the combined voting power
of all classes of stock entitled to vote, or 50 percent or more of the total
value of shares of all classes of stock outstanding.
 
     (i) The Company and the Signing Shareholders represent that the Company is
not under the jurisdiction of a court in a case under Title 11 of the United
States Code, a receivership, foreclosure, or similar proceeding in a federal or
state court.
 
     (j) The Company and the Signing Shareholders represent that the fair market
value of the assets to be transferred from the Company to Merger Sub as a result
of the Merger will equal or exceed the sum of the liabilities of the Company to
be assumed by Merger Sub or Medirisk (plus the amount of liabilities to which
the assets to be transferred are subject).
 
     (k) Medirisk represents the payment of cash to the Shareholders in lieu of
fractional shares of Medirisk Stock will not be a separately bargained for
consideration, but will be undertaken solely for the purpose of avoiding the
expense and inconvenience of issuing and transferring fractional shares, and the
total cash consideration that will be paid to the Company's Shareholders in lieu
of fractional shares of Medirisk Stock will represent less than one (1%) percent
of the total consideration issued in the Merger.
 
     (l) Garton and Chermak severally represent that none of the compensation to
be received by him for services as an employee of the Company represents
separate consideration for, or is allocable to, any of his shares of Company
Stock. Medirisk represents that any compensation to be paid to a
Shareholder-employee who continues as an employee of Medirisk or Merger Sub
subsequent to the Merger will be for services rendered and will be not greater
in amounts than amounts that would be paid to third parties bargaining at arms
length for similar services.
 
     (m) The Company represents that it has no plan or intention to make prior
to the Merger Effective Time, and except as set forth in SCHEDULE 1.6(M), it has
not made, any distributions other than regular, normal dividends to Shareholders
in the three (3) year period prior to the Merger.
 
     (n) The Company represents that except as set forth in SCHEDULE 1.6(N), it
has not reacquired or redeemed any of its stock within the last three years.
 
     (o) The Company represents that at all times during the five-year period
ending on the Merger Effective Time, the fair market value of all of the
Company's United States real property interests was and will have been less than
fifty (50%) percent of the total fair market value of (A) its United States real
property interests, (B) its interests in real property located outside the
United States, and (C) its other assets used or held for use in a trade or
business. For purposes of the preceding sentence, (X) United States real
property interests include all interests (other than an interest solely as a
creditor) in real property and associated personal property (such as movable
walls and furnishings) located in the United States or the Virgin Islands and
interests in any corporation (other than a controlled corporation) owning any
United States real property interest, (Y) the Company is treated as owning its
proportionate share (based on the relative fair market value
 
                                       C-4
<PAGE>   67
 
of its ownership interest to all ownership interests) of the assets owned by any
controlled corporation or any partnership, trust, or estate in which the Company
is a partner or beneficiary, and (Z) any such entity in turn is treated as
owning its proportionate share of the assets owned by any controlled corporation
or any partnership, trust, or estate in which the entity is a partner or
beneficiary. As used in this paragraph, "controlled corporation" means any
corporation at least fifty percent (50%) of the fair market value of the stock
of which is owned by the Company, in the case of a first-tier subsidiary of the
Company, or by a controlled corporation, in the case of a lower-tier subsidiary.
 
     (p) The Company represents that the Company is not a party to, and holds no
assets subject to, a "safe harbor lease" under former Section 168(f)(8) of the
Code and the Regulations thereunder.
 
     (q) The Agreement together with the other agreements to be executed and
delivered in connection with the Closing of the transactions contemplated herein
represent the entire understanding of Company, Medirisk, and Merger Sub with
respect to the Merger.
 
     (r) Medirisk and Merger Sub represent that none of (i) Medirisk, (ii) any
member of Medirisk's affiliated group as defined in Section 1504 of the Code
without regard to Section 1504(b) of the Code, (iii) any corporation in which at
least fifty percent (50%) of the total combined voting power of all classes of
stock entitled to vote or at least fifty percent (50%) of the value of all
classes of stock is owned directly or indirectly by Medirisk or (iv) any entity
that is treated as a partnership for federal income tax purposes and has as an
owner a corporation described in (I), (ii), or (iii) of this paragraph has the
intent at the time of the Closing to acquire or redeem (directly or indirectly)
any Medirisk shares issued in connection with the transactions described herein.
 
     (s) Medirisk and Merger Sub represent and warrant to the Company that
following the Merger, Merger Sub will not issue additional shares of Merger Sub
stock that would result in Medirisk losing control of Merger Sub within the
meaning of Section 368(c) of the Code.
 
     (t) Medirisk represents and warrants to the Company that Medirisk has no
plan or intention to reacquire any of Medirisk's stock issued in the Merger.
 
     (u) Medirisk represents and warrants to the Company that Medirisk has no
plan or intention to: liquidate Merger Sub, merge Merger Sub with and into
another corporation; sell or otherwise dispose of the stock of Merger Sub; or
cause Merger Sub to sell or otherwise dispose of any of the assets of the
Company acquired in the Merger, except for dispositions made in the ordinary
course of business or transfers described in Section 368(a)(2)(C) of the Code.
 
     (v) Medirisk and Merger Sub represent and warrant to the Company that,
following the Merger, Merger Sub will continue the historic business of the
Company or use a significant portion of the Company's business assets in a
business.
 
     (w) Medirisk represents and warrants to the Company that, prior to the
Merger, Medirisk will be in control of Merger Sub within the meaning of Section
368(c) of the Code.

is intended, except for operating systems and third party applications that are
stated in the Owned Software documentation and are readily commercially
available. No Owned Software has been published or disclosed to any other
parties, except as set forth on SCHEDULE 2.10(B) and except pursuant to

Company is required or obligated to pay with respect to Licensed Software. Prior

manner as such Company Software is currently used by the Company. The Company is
not infringing any intellectual property rights of any other person or entity

     7.1 TIME AND PLACE OF CLOSING.  (a) The closing (the "Closing") of the
transactions contemplated by this Agreement will be held on 26 March 1998 or
such other date as the parties may agree. The Closing shall commence at 10:00
a.m. at the offices of Medirisk, Inc., Two Piedmont Center, Suite 400, 3565
Piedmont Road, N.E., Atlanta, Georgia 30305-1502 or at such other time or place

time and date of the Merger solely for accounting purposes shall be 12:01 a.m.
Eastern Time on 23 March 1998 (the "Accounting Effective Date"). By way of
explanation, the parties intend, in light of the de facto control of the
Company's business exerted by Medirisk from and after 23 March 1998, that all
revenue generated after 23 March 1998 shall be for the benefit of Medirisk. The
parties acknowledge that while for accounting purposes the effective date of the
Merger shall be 23 March 1998, no obligations that accrue under contracts or
agreements prior to the Merger Effective Time and no accrued liabilities of the
Company shall be assumed, directly or indirectly, by Medirisk except unless and
until the Merger Effective Time, that no employees or other agents of the
Company shall directly or indirectly become employees or other agents of
Medirisk for any period prior to the Merger Effective Time, and that all
covenants, representations and warranties in the certificates to be provided by
the Shareholders pursuant to Section 5.1 shall be made and dated as of the
Closing Date. Notwithstanding the foregoing, neither the Company nor the
Shareholders shall have any liability nor bear any cost arising from or
associated with Medirisk's inability to account, for any purpose, for the
transaction contemplated hereby on the basis set forth in this Section 7.1(b).

     Shareholders' Representative on behalf of the Shareholders who have
     tendered their certificates representing Company Stock to be allocated
     among such Shareholders as set forth on SCHEDULE 1.5(C) under the heading
     "Allocation of Cash and Medirisk Common Stock Deliverable to

     9.1 METHOD OF TERMINATION.  This Agreement and the transactions

     Medirisk;

     Medirisk or Merger Sub shall (i) fail to perform in any material respect

     warranties or covenants contained herein;
 
          (c) By Medirisk after 31 March 1998, if any Shareholder shall (i) fail
     to perform in any material respect his, her or its agreements contained
     herein required to be performed by him, her or it on or prior to the
     Closing Date, or (ii) materially breach any of his, her or its
     representations, warranties or covenants contained herein;
 
          (d) By the Shareholders' Representative or Medirisk at any time after

<PAGE>   80
 
          (e) By either Medirisk or the Shareholders' Representative if there
     shall be any order, writ, injunction or decree of any court or governmental
     or regulatory agency binding on Medirisk, Merger Sub, the Company or any
     Shareholder, which prohibits or restrains Medirisk, Merger Sub, the Company
     and/or any Shareholder from consummating the Merger hereunder, provided
     that Medirisk and the Shareholders shall have used their reasonable best
     efforts to have any such order, writ, injunction or decree lifted and the
     same shall not have been lifted within ten (10) days after entry, by any
     such court or governmental or regulatory agency.
 
     9.2 NOTICE OF TERMINATION.  Notice of termination of this Agreement, as
provided for in this Article IX, shall be given by the parties so terminating to
the other parties hereto in accordance with Section 10.1 of this Agreement.
 
     9.3 EFFECT OF TERMINATION.  If this Agreement is terminated pursuant to
Section 9.1 hereof, this Agreement shall become void and of no further force and
effect, and each party shall pay the costs and expenses incurred by it in
connection with this Agreement; and, provided the Agreement was not terminated
pursuant to subparagraph (b) or (c) of Section 9.1, no party (or any of its
officers, directors, employees, agents, representatives or shareholders) shall
be liable to any other party for any costs, expenses, damages (direct or
indirect) or loss of anticipated profits. If, however, this Agreement is
terminated pursuant to subparagraphs (b) or (c) of Section 9.1, this Section 9.3
shall not relieve a breaching or defaulting party from any liability to the
other party.
 
     9.4 RISK OF LOSS.  The Company and the Shareholders shall bear all risk of
condemnation, destruction, loss or damage due to fire or other casualty from the
date of this Agreement through the Closing. If the condemnation, destruction,
loss or damage is such that the business of the Company is interrupted or
curtailed or the assets of the Company are materially affected, then Medirisk
shall have the right to terminate this Agreement. If the condemnation,
destruction, loss or damage is such that the business is neither interrupted nor
curtailed or the assets are not materially affected, or if the business of the
Company is curtailed or interrupted or the assets are materially affected and
Medirisk nevertheless forgoes the right to terminate this Agreement, then the
Merger Consideration shall be adjusted at Closing to reflect such condemnation,
destruction, loss or damage to the extent that insurance proceeds are not
sufficient to cover such destruction, loss or damage. If Medirisk, on the one
hand, and the Shareholders, on the other, are unable to agree upon the amount of
such adjustment, then the dispute shall be resolved jointly by the independent
accounting firms then employed by the Company and Medirisk, and if said
accounting firms do not agree, they shall appoint a Designated Accountant (in
the manner prescribed in SCHEDULE 1.5(B)) to make such determination, whose
determination of the dispute shall be final and binding. For purposes of this
Section 9.4 the fees and expenses of the Designated Accountant shall be borne
one-half by Medirisk and one-half by Shareholders.

                                       TO
                         CERTIFICATE OF DESIGNATION OF
                    SERIES 1998-A REDEEMABLE PREFERRED STOCK
 
     1. DESIGNATION.  There is hereby designated a series of preferred stock to
be known as the "Series 1998-A Redeemable Preferred Stock" consisting of Five
Thousand (5,000) shares of the undesignated preferred stock of the Corporation
(the "Series 1998-A Preferred Stock"), which series shall have the following
rights, terms and privileges:
 
     2. DIVIDENDS.  (a) The holders of record of the then outstanding Series
1998-A Preferred Stock shall be entitled to receive when, as and if declared by
the Board of Directors of the Corporation, out of the funds legally available
therefor, cumulative dividends at the annual rate of five percent (5%) per
share. Such dividends shall accrue on each share of Series 1998-A Preferred
Stock from and after the date on which each such share is issued by the
Corporation (the "Issue Date"), shall accrue from day to day, shall be declared
and paid annually on December 31 of each year, and shall be payable in cash.
 
     (b) Subject to the provisions of this Section 2, the Corporation may, in
the Board's discretion, declare and pay dividends or distributions, or make
provision for the payment thereof, on any equity security of the Corporation,
but only if all accrued dividends and distributions on the Series 1998-A
Preferred Stock shall have been paid and made in full prior to the date of any
such declaration, payment, provision or distribution.
 
     3. LIQUIDATION RIGHTS.  (a) In the event of any liquidation, dissolution or
winding up of the affairs of the Corporation, whether voluntary or involuntary,
after payment or provision for payment of the debts and other liabilities and
obligations of the Corporation and payment of the liquidation preference with
shares to any shares of preferred stock of the Corporation ranking senior to
Series 1998-A Preferred Stock upon dissolution, each holder of Series 1998-A
Preferred Stock then outstanding shall be entitled to be paid out of the net
assets of the Corporation available for distribution to the stockholders of the
Corporation prior and in preference to any payment or declaration and setting
apart for payment of any amount in respect of the Common Stock of the
Corporation (the "Common Stock"), an amount equal to the sum of the following:
(i) Ten Thousand Dollars ($10,000.00) per share of Series 1998-A Preferred Stock
held by such holder, and (ii) an amount equal to all accrued and unpaid
dividends thereon, whether or not declared, to and including the date full
payment shall be tendered to the holders of the Series 1998-A Preferred Stock
with respect to such liquidation, dissolution or winding up (clauses (i) and
(ii), collectively the "Series 1998-A Liquidation Preference"); if upon any
liquidation, dissolution or winding up of the Corporation, whether voluntary or
involuntary, the assets to be distributed to the holders of the Series 1998-A
Preferred Stock shall be insufficient to permit the payment to such holders of
the full aggregate amount of the Series 1998-A Liquidation Preference, then all
of the net assets of the Corporation available for distribution to its
shareholders shall be distributed ratably among the holders of the Series 1998-A
Preferred Stock in proportion to the then applicable Series 1998-A Liquidation
Preference.
 
     (b) Upon the completion of the distribution required by Section 3(a) above,
if assets of the Corporation remain to be distributed, the holders of Common
Stock of the Corporation and any shares ranking on liquidation junior to the
Series 1998-A Preferred Stock shall be entitled to the remaining assets of the
Corporation.
 
     (c) Written notice of any such liquidation, dissolution or winding up,
stating a payment date, the place where such payment shall be made, shall be
given to the holders of the Series 1998-A Preferred Stock not later than ten
(10) business days prior to such payment date.
 
     (d) Whenever the distribution provided for in this Section 3 shall be
payable in property other than cash, the value of such distribution shall be the
fair market value of such property as determined in good faith by the
Corporation's Board of Directors.
 
     4. VOTING RIGHTS.  Except as otherwise expressly provided herein or as
required by law, the holders of Series 1998-A Preferred Stock shall be entitled
to vote on all matters upon which holders of Common Stock have the right to vote
and, with respect to such vote, shall be entitled to notice of any meeting of
the
 
                                       D-2
<PAGE>   86
 
Corporation's stockholders in accordance with the bylaws of the Corporation, and
shall be entitled to a number of votes per share of Series 1998-A Preferred
Stock equal to the number of shares of Common Stock into which a share of Series
1998-A Preferred Stock is then convertible as provided in Section 6 below.
Except as otherwise expressly provided herein, or to the extent class or series
voting is otherwise required by law, the holders of Series 1998-A Preferred
Stock and Common Stock shall vote together as a single class and not as separate
classes. Notwithstanding any provision of the Certificate of Incorporation or
the Delaware General Corporation Law, as amended, to the contrary, the Board of
Directors may at any time and from time to time include additional shares in the
designation of Series 1998-A Preferred Stock, designate one or more series or
classes of preferred stock with liquidation preferences, voting rights, dividend
rights and other rights and privileges senior to the Series 1998-A Preferred
Stock without the vote or consent of, or notice to, the holders of the Series
1998-A Preferred Stock.
 
     5. REDEMPTION RIGHTS.  (a) Effective upon the fifth anniversary of any
Issue Date, the Corporation may redeem for cash all, but not less than all, of
the shares of Series 1998-A Preferred Stock issued on such Issue Date that are
then outstanding by giving notice to the holders thereof of such redemption.
Dividends shall cease to accrue on any share of Series 1998-A Preferred Stock
for which notice of redemption has been given by the Corporation as of the date
fixed in such notice for redemption, and such shares to be redeemed shall cease
to be outstanding as of such date and shall represent only the right to receive
the Redemption Price therefor, without interest. With such notice of redemption
the Corporation shall include a letter of transmittal or other instructions
regarding the surrender of certificates representing Series 1998-A Preferred
Stock and the receipt of payment therefor. The redemption price for any shares
redeemed pursuant to this Section 5(b) shall be the Series 1998-A Liquidation
Preference (the "Redemption Price"), and the Redemption Price shall be paid by
the Corporation to the holder of Series 1998-A Preferred Stock upon surrender to
the Corporation of the certificate(s) representing the Series 1998-A Preferred
Stock being redeemed duly endorsed for transfer or accompanied by blank stock
powers.
 
     (b) Effective upon the twentieth anniversary of each Issue Date, the
Corporation shall redeem for cash all, but not less than all, of the shares of
Series 1998-A Preferred Stock issued on such Issue Date that are then
outstanding by giving notice to the holders thereof of such redemption.
Dividends shall cease to accrue on any share of Series 1998-A Preferred Stock
for which notice of redemption has been given by the Corporation as of the date
fixed in such notice for redemption, and such shares to be redeemed shall cease
to be outstanding as of such date upon payment of, or provision for payment of,
the redemption price therefor, and shall represent only the right to receive the
Redemption Price therefor, without interest. With such notice of redemption the
Corporation shall include a letter of transmittal or other instructions
regarding the surrender of certificates representing Series 1998-A Preferred
Stock and the receipt of payment therefor. The redemption price for any shares
redeemed pursuant to this Section 5(b) shall be the Redemption Price, and the
Redemption Price shall be paid by the Corporation to the holder of Series 1998-A
Preferred Stock upon surrender to the Corporation of the certificate(s)
representing the Series 1998-A Preferred Stock being redeemed duly endorsed for
transfer or accompanied by blank stock powers.
 
     6. MANDATORY CONVERSION.  (a) If, while any shares of Series 1998-A
Preferred Stock are outstanding, the Market Value (as defined below) equals or
exceeds the Series 1998-A Conversion Price (as defined below), then each share
of Series 1998-A Preferred Stock shall automatically and without any action on
the part of the holder thereof or the Corporation be converted into a number of
shares of Common Stock that results from dividing the Series 1998-A Liquidation
Preference by the Series 1998-A Conversion Price in effect at the time of
conversion of such Series 1998-A Preferred Stock.
 
     (b) For purposes of this Certificate of Designation, the term "Market
Value" means, on any date, the average of the daily closing prices per share of
Common Stock for the twenty (20) consecutive Trading Days (as defined below)
immediately prior to such date; provided that such twenty (20) consecutive
Trading Days shall in no event include any Trading Day (i) before the first full
Trading Day after the first public announcement of the issuance of a dividend or
other distribution on the Common Stock, or (ii) after the last full Trading Day
prior to the commencement of "ex-dividend" trading on the exchange or market
specified in the following sentence. The closing price for each day shall be the
last sale price or, in case no sale takes place on such day, the average of the
closing bid and asked prices, in either case as reported in the principal
 
                                       D-3
<PAGE>   87
 
consolidated transaction reporting system with respect to the principal national
securities exchange or Nasdaq National Market on which the Common Stock is then
listed or admitted to trading or, if the Common Stock is not so listed or
admitted to trading, the last quoted sale price or, if not so quoted, the
average of the bid and asked prices in the over-the-counter market as reported
by the Nasdaq Stock Market or such other system then in use, or, if on any such
date the Common Stock is not quoted by any such organization, the average
closing bid and asked prices as furnished by a professional market maker making
a market in the Common Stock selected by the Board of Directors of the
Corporation. For purposes of this Certificate of Designation, the term "Trading
Day" means a day on which the principal securities exchange on which the Common
Stock is listed or admitted to trading is open for the transaction of business
or, if the Common Stock is not so listed or admitted to trading, any day other
than a Saturday, Sunday or a day on which banking institutions in the State of
New York are authorized or obligated by law or executive order to close.
 
     (c) For purposes of this Certificate of Designation, the term "Series
1998-A Conversion Price" means $22.6094, adjusted as provided in the next
succeeding sentence. If the Corporation shall at any time or from time to time
after March 31, 1998 effect a subdivision or combination of its outstanding
Common Stock (whether by stock split, stock dividend or otherwise), the Series
1998-A Conversion Price in effect immediately before that subdivision or
combination shall be proportionately adjusted by multiplying the then effective
Series 1998-A Conversion Price by a fraction, (i) the numerator of which is the
number of shares of Common Stock issued and outstanding immediately prior to
such subdivision or combination, and (ii) the denominator of which is the number
of shares of Common Stock issued and outstanding immediately after such
subdivision or combination. The number of shares of Common Stock outstanding at
any time shall, for the purposes of this Section 6(c), include the number of
shares of Common Stock into which any convertible securities of the Corporation
may be converted, or for which any warrant, option or rights of the Corporation
may be exchanged. Any adjustment under this Section 6(c) shall become effective
at the close of business on the date the subdivision or combination becomes
effective.
 
     (d) If at any time or from time to time there shall be (i) a capital
reorganization of the Common Stock (other than a subdivision or combination of
shares provided for in Section 6(c) above) or (ii) a merger, consolidation or
statutory share exchange of the Corporation with or into another corporation in
which consolidation, merger or statutory share exchange persons owning capital
stock of the Corporation immediately prior to the consolidation, merger or share
exchange own less than a majority of the voting stock of the resulting,
surviving or exchanging corporation, or (iii) the sale of all or substantially
all the Corporation's properties and assets or capital stock to any other
person, then, as a part of such reorganization, merger, consolidation, share
exchange or sale (a "Transaction"), provision shall be made so that the holders
of the Series 1998-A Preferred Stock shall receive in the Transaction payment of
the Series 1998-A Liquidation Preference or shall, after the Transaction, be
entitled to receive, upon conversion of the Series 1998-A Preferred Stock, the
number of shares of stock or other securities or property of the Corporation, or
of the successor corporation resulting from the Transaction, to which a holder
of the maximum number of Common Stock into which such Series 1998-A Preferred
Stock would then be converted would have been entitled on the Transaction. In
any such case, appropriate adjustment shall be made in the application of the
provisions of this Section 6 with respect to the rights of the holders of the
Series 1998-A Preferred Stock after the Transaction to the end that the
provisions of this Section 6 (including adjustment of the Series 1998-A
Conversion Price then in effect and the number of shares issuable upon
conversion of the Series 1998-A Preferred Stock) shall be applicable after that
event as nearly equivalent as may be practicable.
 
     (e) The provisions of subsections (c) and (d) of this Section 6 shall apply
to successive issuances, dividends or other distributions, subdivisions and
combinations or Transactions on or of Common Stock after March 31, 1998.
 
     (f) In each case of an adjustment or readjustment of the Series 1998-A
Conversion Price, the Corporation, at its expense, shall cause independent
certified public accountants of recognized standing selected by the Corporation
(who may be the independent certified public accounts then auditing the books of
the Corporation) to compute such adjustment or readjustment in accordance with
this Certificate of Designation and prepare a certificate showing such
adjustment or readjustment, and shall mail such
 
                                       D-4
<PAGE>   88
 
certificate, by first-class mail, postage prepaid, to each registered holder of
the Series 1998-A Preferred Stock at the holder's address as shown in the
Corporation's books.
 
     (g) No fractional shares of Common Stock shall be issued upon conversion of
Series 1998-A Preferred Stock. In lieu of any fractional shares to which the
holder would otherwise be entitled, the Corporation shall pay cash equal to the
product of such fraction multiplied by the Market Value on the date of
conversion. Whether or not fractional shares are issuable upon such conversion
shall be determined on the basis of the total number of shares of Series 1998-A
Preferred Stock held by the holder that is at the time being converted into
Common Stock and the number of shares of Common Stock issuable upon such
aggregate conversion.
 
     (h) The Corporation shall at all times reserve and keep available out of
its authorized but unissued Common Stock such number of shares of Common Stock
as may from time to time be required, at such time, to be issued by the
Corporation upon exercise of all then-exercisable warrants and options to
purchase shares of Common Stock or the right to convert other convertible
securities into shares of Common Stock and such number of shares of Common Stock
as shall from time to time be sufficient to effect the conversion of all
outstanding shares of Series 1998-A Preferred Stock.
 
     (i) Any notice required by the provisions of this Section 6 to be given to
the holders of the Series 1998-A Preferred Stock shall be deemed given when
personally delivered to such holder or five business days after the same has
been deposited in the United States mail, certified or registered mail, return
receipt requested, postage prepaid, and addressed to each holder of record at
this address appearing on the books of the Corporation.
 
     (j) The Corporation will pay all taxes and other governmental charges
(other than taxes measured by the revenue or income of the holders of the Series
1998-A Preferred Stock) that may be imposed in respect of the issue or delivery
of Common Stock upon conversion of the Series 1998-A Preferred Stock.
 
     (k) No Series 1998-A Preferred Stock acquired by the Corporation by reason
of redemption, purchase, conversion or otherwise shall be reissued, and all such
shares shall be canceled, retired and eliminated from the shares which the
Corporation shall be authorized to issue
