                              EMPLOYMENT AGREEMENT
                                       OF
                               GREGORY T. STEVENS


         THIS EMPLOYMENT AGREEMENT ("Agreement") is entered into between ENVOY
Corporation, a Tennessee corporation ("Company"), and Gregory T. Stevens
("Executive"), effective as of April 1, 1998 (the "Effective Date"). The Company
and the Executive are sometimes referred to herein as the "Parties".

         In consideration of the mutual covenants contained in this Agreement
and other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, and intending to be legally bound, the parties hereby agree
as follows:

1.       Employment:  The Company hereby employs the Executive and the Executive
hereby accepts employment with the Company upon terms and conditions set 
forth herein.

2.       Duties and Responsibilities:

         2.1 Extent of Service: The Executive shall, during the term of this
Agreement, devote such of his entire time, attention, energies and business
efforts ("Business Efforts") to his duties as an Executive of the Company as are
reasonably necessary to carry out his duties specified in Paragraph 2.2 below.
The Executive shall not, during the term of this Agreement, engage in any other
business activity (whether or not such business activity is pursued for gain,
profit or other pecuniary advantage) if such business activity would impair the
Executive's ability to carry out his duties hereunder. This Paragraph 2.1,
however, shall not be construed to prevent the Executive from investing his
personal assets as a passive investor.

         2.2 Position and Duties: The Executive shall serve the Company as Vice
President, General Counsel and Secretary and, in such capacities, shall be the
chief legal officer for the Company and its affiliates and shall have principal
responsibility for all legal matters relating to the Company Business (as
defined in Section 9.1 below). In furtherance hereof, the parties agree that a
significant portion of the Executive's responsibilities shall include those
legal matters typically associated with being the chief legal officer of a
publicly traded company. The Executive shall perform, faithfully and diligently,
the services and functions relating to such offices or otherwise reasonably
incident to such offices as may be designated from time to time by the Board of
Directors of the Company; provided that all such services and functions shall be
reasonable and within the Executive's area of expertise; and provided further
that the Executive shall be physically capable of performing the same.

         2.3 Place of Employment: During the term of this Agreement, the
Executive's primary place of employment shall be in Nashville, Tennessee, unless
otherwise mutually agreed by the



   2



Company and Executive. During the term of this Agreement, the Company will
provide the Executive with a private office and other customary staff support
services, all as are commensurate with the services and functions to be
performed by him hereunder.

3. Salary and Other Benefits: Subject to the terms and conditions of this
Agreement:

         3.1 Salary: As compensation for his services under and during the term
of his employment under this Agreement, the Executive shall be paid an annual
salary of not less than $137,500, payable in accordance with the then current
payroll policies of the Company. Such salary shall be subject to increase by the
Board of Directors of the Company (or the appropriate committee thereof) at the
beginning of each calendar year, or otherwise as consistent with the timing of
employee pay increases. The annual salary shall be payable pursuant to this
Paragraph 3.1 in accordance with the Company's regular payroll practices from
time to time (hereinafter sometimes referred to as his "Base Salary").

         3.2 Other Benefits: As long as the Executive is employed by the
Company, the Executive shall be entitled to receive the following benefits in
addition to his Base Salary:

                  (a) The Executive shall have the right to participate in all
         group benefit plans of the Company (including without limitation,
         disability, accident, medical, life insurance, hospitalization and
         pension) and stock and other incentive plans (including without
         limitation stock option, stock appreciation or other similar stock
         based plans), all in accordance with the Company's regular practices
         with respect to its senior management employees.

                  (b) The Executive shall be entitled to reimbursement from the
         Company for reasonable out-of-pocket expenses incurred by him in the
         course of the performance of his duties hereunder. Executive also shall
         be entitled to reimbursement for professional fees and expenses,
         including without limitation bar association dues and continuing legal
         education seminar fees, as are customary to maintain his position and
         standing as a licensed attorney in the State of Tennessee and in his
         areas of expertise.

                  (c) The Company shall pay Executive an annual bonus, payable
         during the first quarter of each year, or otherwise as consistent with
         the timing of the payment of other employee bonuses, based on the
         previous year's performance, of up to 20% (or such additional amount as
         may otherwise be determined by the Board of Directors) of his then
         current Base Salary (the "Bonus"), subject to performance criteria
         established by the Board of Directors.

                  (d) The Executive shall be entitled to such vacation, holidays
         and other paid or unpaid leaves of absence as are consistent with the
         Company's other senior management employees. Executive shall be
         entitled to twenty-eight (28) days of paid vacation each



                                        2

   3



         year. This vacation allowance shall be cumulative from year to year,
         but shall be limited to six (6) weeks accumulation. Executive
         recognizes the essential nature of his duties and hereby agrees the
         maximum amount of vacation time to be taken shall not exceed
         twenty-eight (28) consecutive days.

4.    Term: The term of this Agreement shall be for an initial period of thirty
(30) months following the Effective Date (the "Initial Term"), and shall
thereafter automatically be extended for additional periods of one year on a
yearly basis, unless on or before 60 days prior to the expiration of any
subsequent year period, either the Executive or the Company gives the other
party notice that the term of this Agreement will not be so extended, in which
case the term of this Agreement will end at the end of such period as designated
in the notice.

5.    Termination and Resignation: During the Initial Term, the Company shall 
have the right to terminate the Executive's employment hereunder at any time
only for Cause. Following the Initial Term, the Company shall have the right to
terminate Executive's employment hereunder at any time and for any reason. Upon
any termination by the Company, the Executive shall be entitled to receive from
the Company prompt payment of the amounts determined pursuant to Paragraph 6.
The Executive shall have the right to terminate his employment hereunder at any
time by resignation, and he shall thereupon be entitled to receive from the
Company prompt payment of the amount determined pursuant to Paragraph 6 below.

6.    Certain Payments Upon Termination and Resignation:

      6.1 Pro Rata Payments: If (a) the Company at any time terminates the
Executive's employment for Cause (as defined in Section 6.3 below) or (b) the
Executive voluntarily resigns for any reason other than because of an uncured
material breach by the Company of any term of this Agreement prior to a Change
in Control (as defined in Section 7.3(c) below), then in each case the Executive
shall be entitled to receive only his Base Salary and any other accrued benefits
due Executive in accordance with Paragraph 3.2(a) on a pro rata basis to the
date of termination plus reimbursement of expenses through the date of
termination in accordance with Paragraph 3.2(b). If the Executive at any time
dies or becomes disabled (being defined as the inability of the Executive to
perform his normal employment duties for the remainder of the term of this
Agreement because of either physical or mental incapacity), the Executive shall
be entitled to receive only his Base Salary and any other accrued benefits due
Executive in accordance with Paragraph 3.2(a) on a pro rata basis and
reimbursement of expenses in accordance with Paragraph 3.2(b) to the date of
termination or resignation. For purposes of this Paragraph 6.1, "pro rata" shall
mean the product of the Executive's annual Base Salary that would have been
payable had the Executive's employment not terminated multiplied by a fraction
the denominator of which is 365 and the numerator of which is the number of days
during the calendar year that have passed through the date of the termination of
the Executive's employment.

   4



         6.2 Base Salary Payment: If (a) the Company terminates this Agreement
or the Executive's employment without Cause or (b) the Executive resigns because
of the uncured material breach by the Company of any term of this Agreement,
then in each case the Executive shall be entitled to receive his Base Salary for
a period of six months following such termination, payable on a pro rata basis,
in accordance with the Company's regular payroll practices. Furthermore, if
Executive has not secured regular full-time employment within the six month
period following such termination date, the Company will continue to pay his
current Base Salary for up to an additional six months or until such time as
Executive secures regular full-time employment, whichever is the earlier to
occur. The additional six months pay will be evaluated on a monthly basis.
Following such termination and in furtherance hereof, Executive agrees to
actively seek new regular full-time employment, to provide the Company evidence
of his efforts to secure new regular full-time employment and to promptly notify
the Company if he secures such employment.

         6.3 Definition of Cause: Termination by the Company of the Executive's
employment for "Cause" shall mean termination (a) upon the willful
misappropriation of funds or properties of the Company; (b) the willful
contravention of the standards referred to in the last sentence of Paragraph 8
below; (c) Executive's gross negligence in the performance of his duties
hereunder, intentional nonperformance or misperformance of such duties, or
refusal to abide by or comply with the directives of the Board of Directors, his
superior officers, the Company's policies and procedures, which actions continue
for a period of at least five days after receipt by the Executive of written
notice of the need to cure or cease; (d) Executive's willful dishonesty, fraud,
or misconduct with respect to the business or affairs of the Company; and (e)
Executive's conviction of a felony or other crime involving moral turpitude. For
purposes of this definition, no act, or failure to act, on the Executive's part
shall be considered "willful" unless done, or omitted to be done, by the
Executive not in good faith and without reasonable belief that the Executive's
action or omission was in the best interest of the Company.

7.       Effect of Change in Control:

         (a) Contemporaneously with the occurrence of a Change in Control of the
Company, all outstanding options previously granted to the Executive under any
then existing Company stock option, stock appreciation or other employee
incentive plan that are not otherwise exercisable by the Executive at the time
the Change in Control of the Company occurs shall immediately vest and remain
exercisable for a period of no less than 90 days from such date.

         (b) Following a Change in Control, if (i) the Company fails to cure a
material breach hereunder by the Company or (ii) Executive's duties,
responsibilities or authority are materially different than prior to the Change
in Control, then in each case, the Executive will be entitled, in his sole
discretion, to voluntarily resign at any time thereafter and receive the Base
Salary payments as set forth in Section 6.2 plus an amount equal to Executive's
then current Bonus amount. Furthermore, if not previously vested in accordance
with subsection (a) above, all


                                        4

   5



outstanding options previously granted to the Executive under any then existing
stock option, stock appreciation or other employee incentive plan of the Company
(or any successor plan) that are not otherwise exercisable by the Executive
shall immediately vest and remain exercisable by Executive for a period of no
less than 90 days from such date.

         (c) A "Change in Control" shall be conclusively deemed to have occurred
if (and only if) any of the following shall have taken place: (i) a change in
control is reported by the Company in response to either Item 6(e) of Schedule
14A of Regulation 14A promulgated under the Securities Exchange Act of 1934, as
amended ("Exchange Act"), or Item 1 of Form 8-K promulgated under the Exchange
Act; (ii) any person (as such term is used in Section 13(d) and 14(d)(2) of the
Exchange Act) is or becomes the beneficial owner (as defined in Rule 13d-3 under
the Exchange Act) directly or indirectly, of securities of the Company
representing forty percent or more of the combined voting power of the Company's
then outstanding securities; or (iii) following the election or removal of
directors, a majority of the Board consists of individuals who were not members
of the Board two years before such election or removal, unless the election of
each director who was not a director at the beginning of such two-year period
has been approved in advance by directors representing at least a majority of
the directors then in office who were directors at the beginning of the two-year
period.

8.       Preservation of Business; Fiduciary Responsibility: The Executive shall
use his reasonable best efforts to preserve the business and organization of the
Company, to keep available to the Company the services of present employees and
to preserve the business relations of the Company with suppliers, distributors,
customers and others. The Executive shall not commit any act, or in any way
assist others to commit any act, which could reasonable be expected to injure
the Company in any material respect. So long as the Executive is employed by the
Company, the Executive shall observe and fulfill proper standards of fiduciary
responsibility attendant upon his service and office.

9.       Restrictive Covenants:

         9.1 Covenants Against Competition: Executive acknowledges that (a) the
business of the Company and its affiliates is as described in the Company's
annual report on Form 10-K as filed with the Securities and Exchange Commission
for its fiscal year ended December 31, 1997, and thereafter as described in each
successive annual report on Form 10-K filed by the Company (the "Company
Business"); and (b) Executive's work relating to Company Business will bring him
into close contact with many confidential matters not readily available to the
public.

         9.2 Non-Compete: During the term of this Agreement and for a period of
one (1) year following the termination of Executive's employment with the
Company (including any renewal periods as provided in Paragraph 4), whether
Executive's employment terminates pursuant to the provisions of Paragraph 5 of
this Agreement or otherwise (collectively, the "Restricted Period"), Executive
covenants and agrees that he will not, without the express approval of the Board
of


                                        5

   6



Directors, anywhere in the continental United States engage in any business, as
an individual, partner, shareholder, officer, director, principal, agent,
employee, trustee or consultant, if such business is competitive with the
Company Business; provided, however, that Executive may (a) own, directly or
indirectly, solely as an investment, securities of any entity if Executive (i)
is not a controlling person with respect to such entity and (ii) does not,
directly or indirectly, own five percent or more of any class of the securities
of such entity and (b) nothing in this Section 9.2 shall be deemed to prohibit
Executive from engaging in the private practice of law during the Restricted
Period.

         9.3 Trade Secrets; Confidential Information: Executive covenants and
agrees that at all times during and after the Restricted Period, he shall keep
secret and not disclose to others or appropriate to his own use or the use of
others any trade secrets, or secret or confidential information or knowledge
pertaining to the Company Business or the affairs of the Company or any of its
affiliates including without limitation trade know-how, trade secrets,
consultant contracts, customer lists, pricing policies, operational methods,
marketing plans or strategies, product development techniques or plans, business
acquisition plans, new personnel acquisition plans, technical processes, designs
and design projects, inventions and research projects. Information shall not be
deemed confidential or secret for purposes of this Agreement if it is generally
known in the industry.

         9.4 Executives of the Company: During the Restricted Period, Executive
shall not directly or indirectly hire away or solicit to hire away from the
Company or any of its affiliates any employee of the Company Business or its
affiliates.

         9.5 Property of the Company: All memoranda, notes, lists, records and
other documents (and all copies thereof) made or compiled by Executive relating
to the Company Business or made available to Executive during his employment by
the Company concerning the business or affairs of the Company Business or any of
its affiliates, other than any of such which may also pertain personally to
Executive or were derived from or constitute legal form documents made or
developed by Executive in his capacity as an attorney, shall be the exclusive
property of the Company and shall be delivered to the Company promptly upon the
termination of Executive's employment with the Company or at any other time on
request by the Board of Directors of the Company or such affiliates.

         9.6 Rights and Remedies Upon Breach: If Executive breaches, or
threatens to commit a breach of, any of the provisions of Paragraphs 9.2 through
9.5 of this Agreement (collectively, the "Restrictive Covenants"), the Company
shall have the following rights and remedies, each of which shall be independent
of the other and severally enforceable, and all of which shall be in addition
to, and not in lieu of, any other rights and remedies available to the Company:
(a) the right and remedy to have any of the Restrictive Covenants specifically
enforced by any court having jurisdiction and in Tennessee by an arbitration
panel as provided in Paragraph 12 of this Agreement, it being hereby
acknowledged and agreed by Executive that any such breach or


                                        6

   7



threatened breach will cause irreparable injury to the Company and that money
damages will not provide an adequate remedy to the Company; and (b) the right
and remedy to require Executive to account for and pay over to the Company all
compensation, profits, monies, accruals, increments or other benefits derived or
received by Executive as a result of any transactions constituting a breach of
any of the Restrictive Covenants, and Executive shall account for and pay over
such benefits to the Company.

         9.7 Severability of Restrictive Covenants: If it is determined that any
of the Restrictive Covenants, or any part thereof, is invalid or unenforceable,
the remainder of the Restrictive Covenants shall not thereby be affected and
shall be given full effect, without regard to the invalid portions. If it is
determined that any of the Restrictive Covenants, or any part thereof, is
unenforceable because of the duration of such provision, the geographical area
covered thereby, or any other determination of unreasonableness of the
provision, the arbitration panel making such determination shall have the power
to reduce the duration, area or scope of such provision and, in its reduced
form, such provision shall then be enforceable and shall be enforced.

10.      Notice: All notices, requests, demands and other communications given 
under or by reason of this Agreement shall be in writing and shall be deemed
given when delivered in person, by facsimile or other electronic transmission or
when mailed, by certified mail (return receipt requested), postage prepaid,

12.      Arbitration: Any dispute or controversy arising under or in connection
with this Agreement shall be settled by arbitration in Nashville, Tennessee. In
the proceeding, the Executive shall select one arbitrator, the Company shall

accordance with the rules of the American Arbitration Association. Judgment may
be entered on the arbitrators' award in any court having jurisdiction.

waiver, change, modification, extension or discharge is sought.

15.      Severability: If any provision of the Agreement is rendered or declared
illegal or unenforceable by reason of any existing or subsequently enacted
legislation or by the decision of any arbitrator or by decree of a court of last
resort, the Parties shall promptly meet and negotiate substitute provisions for
those rendered or declared illegal or unenforceable to preserve the original
intent of this Agreement to the extent legally possible, but all other
provisions of this Agreement shall remain in full force and effect.

16.      Assignments: The Company may assign (whether by operation of law or

respect to assignments, this Agreement shall be binding upon the Executive and 
his heirs, executors,

administrators, legal representatives and assigns and upon the Company and
respective successors and assigns.

18.      Execution: This Agreement may be executed in multiple counterparts each

the same instrument.
